Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Summary of Significant Accounting Principles

Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. In management’s opinion, the accompanying financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the results for the interim periods presented.

     Interim financial results are not necessarily indicative of results anticipated for the full year. These unaudited financial statements should be read in conjunction with the Company’s 2006 audited financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006, as filed with the Securities and Exchange Commission (SEC) on February 28, 2007.

     The preparation of financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Fiscal Year

     The Company’s fiscal year consists of 52 or 53 weeks ending the Sunday closest to December 31, with quarters of 13 or 14 weeks ending the Sunday closest to March 31, June 30, and September 30. The three months ended April 1, 2007 and April 2, 2006 were both 13 weeks.

Revenue Recognition

     The Company’s revenue is generated primarily from the sale of products and services. Product revenue consists of sales of arrays, reagents, instrumentation, and oligonucleotides (oligos), which are short sequences of DNA. Service and other revenue consists of revenue received for performing genotyping services, extended warranty sales and revenue earned from milestone payments.

     The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price to the buyer is fixed or determinable and collectibility is reasonably assured. In instances where final acceptance of the product or system is required, revenue is deferred until all the acceptance criteria have been met. All revenue is recorded net of any applicable allowances for returns or discounts.

     Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided no significant obligations remain and collection of the receivables is reasonably assured. Revenue from the sale of instrumentation is recognized when earned, which is generally upon shipment. However, in the case of BeadLabs, revenue is recognized upon the completion of installation, training and the receipt of customer acceptance. Revenue for genotyping services is recognized when earned, which is generally at the time the genotyping analysis data is delivered to the customer or as specific milestones are achieved.

     In order to assess whether the price is fixed and determinable, the Company ensures there are no refund rights. If payment terms are based on future performance, the Company defers revenue recognition until the price becomes fixed and determinable. The Company assesses collectibility based on a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If the Company determines that collection of a payment is not reasonably assured, revenue recognition is deferred until the time collection becomes reasonably assured, which is generally upon receipt of payment.

     Sales of instrumentation generally include a standard one-year warranty. The Company also sells separately priced maintenance (extended warranty) contracts, which are generally for one or two years, upon the expiration of the initial warranty. Revenue for extended warranty sales is recognized ratably over the term of the extended warranty period. Reserves are provided for estimated

6

product warranty expenses at the time the associated revenue is recognized. If the Company were to experience an increase in warranty claims or if costs of servicing its warrantied products were greater than its estimates, gross margins could be adversely affected.

     While the majority of its sales agreements contain standard terms and conditions, the Company does enter into agreements that contain multiple elements or non-standard terms and conditions. Emerging Issues Task Force (EITF) No. 00-21, Revenue Arrangements with Multiple Deliverables, provides guidance on accounting for arrangements that involve the delivery or performance of multiple products, services, or rights to use assets within contractually binding arrangements. Significant contract interpretation is sometimes required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, and if so, how the price should be allocated among the deliverable elements, when to recognize revenue for each element, and the period over which revenue should be recognized. The Company recognizes revenue for delivered elements only when it determines that the fair values of undelivered elements are known and there are no uncertainties regarding customer acceptance.

     A third source of revenue, research revenue, consists of amounts performed under government grants, which is recognized in the period during which the related costs are incurred. All revenue is recorded net of any applicable allowances for returns or discounts.

Cash and Cash Equivalents

     Cash and cash equivalents are comprised of short-term, highly liquid investments primarily consisting of commercial paper and money market-type funds.

Investments

     The Company applies Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities, to its investments. Under SFAS No. 115, the Company classifies its investments as “available-for-sale” and records such assets at estimated fair value in the balance sheet, with unrealized gains and losses, if any, reported in stockholders’ equity. As of April 1, 2007, the Company’s excess cash balances were primarily invested in marketable debt securities, including commercial paper, auction rate certificates and corporate bonds and notes, with strong credit ratings or short maturity mutual funds providing similar financial returns. The Company limits the amount of investment exposure as to institutions, maturity and investment type.

Restricted Cash

     As of April 1, 2007, restricted cash, included in cash and cash equivalents, consisted of bank guarantees totaling approximately $2.8 million primarily associated with two sales contracts entered into during 2006 and 2007. Both guarantees are scheduled to be released during 2007. There was no restricted cash as of April 2, 2006.

Stock-Based Compensation

     On January 2, 2006, the Company adopted SFAS No. 123 (revised 2004), Share-Based Payment, which addresses the accounting for stock-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. The Company uses the Black-Scholes-Merton option-pricing model to determine the fair-value of stock-based awards under SFAS No. 123R.

     Net loss per basic and diluted share was increased by $0.14 for the three months ended April 1, 2007 as a result of the adoption of SFAS No. 123R. Stock-based compensation expense capitalized as part of inventory as of April 1, 2007 was approximately $0.3 million. As of April 1, 2007, approximately $107.5 million of total unrecognized compensation cost related to stock options, restricted stock and ESPP shares issued to date is expected to be recognized over a weighted-average period of approximately two and a half years.

     The Company has elected to use the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life, and interest rates. The expected volatility is based on the historical volatility of the Company’s

7

common stock over the most recent period generally commensurate with the estimated expected life of the Company’s stock options, adjusted for the impact of unusual fluctuations not reasonably expected to recur and other relevant factors. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees.

     The assumptions used for the specified reporting periods and the resulting estimates of weighted-average fair value per share of options granted and for stock purchases under the ESPP during those periods are as follows:

	Three Months Ended
	April 1, 2007			April 2, 2006
Interest rate – stock options		4.71 – 4.75	%		4.36 – 4.57	%
Interest rate – stock purchases		4.83 – 4.86	%		4.85 – 4.86	%
Volatility – stock options		69 – 70	%		76 – 77	%
Volatility – stock purchases		75 – 76	%		76	%
Expected life – stock options	6 years			6 years
Expected life – stock purchases	6-12 months			6 – 12 months
Expected dividend yield		0	%		0	%
Weighted average fair value per share of options granted	$	25.82		$	14.91
Weighted average fair value per share of employee stock purchases	$	11.84		$	8.11

Net Loss per Share

     Basic and diluted net loss per share is presented in conformity with SFAS No. 128, Earnings per Share, for all periods presented. In accordance with SFAS No. 128, basic net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share is typically computed using the weighted average number of common and dilutive common equivalent shares from stock options using the treasury stock method. However, for all periods presented, diluted net loss per share is the same as basic net loss per share because the Company reported a net loss and therefore the inclusion of weighted average shares of common stock issuable upon the exercise of stock options and warrants would be anti-dilutive. The following table presents the calculation of weighted-average shares used to calculate basic and diluted net loss per share (in thousands):

	Three Months Ended
	April 1, 2007			April 2, 2006
Weighted-average shares outstanding		53,455			41,515
Less: Weighted-average shares of common stock subject to repurchase		(33	)		(40	)
Weighted-average shares used in calculating basic and diluted net loss per share		53,422			41,475

     The total number of shares excluded from the calculation of diluted net loss per share, prior to application of the treasury stock method, was 9,210,422 and 8,189,566 for the three months ended April 1, 2007 and April 2, 2006, respectively. The total number of warrants excluded from the calculation of diluted net loss per share was 1,894,560 for the three months ended April 1, 2007. These warrants were assumed as part of the Company’s merger with Solexa, Inc. on January 26, 2007.

Comprehensive Income (Loss)

     Comprehensive income (loss) is comprised of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on the Company’s available-for-sale securities, changes in the fair value of derivatives designated as effective cash flow hedges, and foreign currency translation adjustments.

     The components of other comprehensive income (loss) are as follows (in thousands):

	Three Months Ended
	April 1, 2007			April 2, 2006
Net loss	$	(298,076	)	$	(104	)
Foreign currency translation adjustments		136			285
Unrealized loss on investments		(10,824	)		(42	)
Total other comprehensive income (loss)	$	(308,764	)	$	139

Recent Accounting Pronouncements

     In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. This Statement applies only to fair value measurements that are already required or permitted by other accounting standards. Accordingly, this Statement does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning after December 15, 2007. The Company is currently evaluating the impact, if any, the adoption of SFAS No. 157 will have on its consolidated results of operations and financial position.

     In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115. SFAS No. 159 expands the use of fair value accounting but does not affect existing standards which require assets or liabilities to be carried at fair value. Under SFAS No. 159, a company may elect to use fair value to measure accounts and loans receivable, available-for-sale and held-to-maturity securities, equity method investments, accounts payable, guarantees and issued debt. Other eligible items include firm commitments for financial instruments that otherwise would not be recognized at inception and non-cash warranty obligations where a warrantor is permitted to pay a third party to provide the warranty goods or services. If the use of fair value is elected, any upfront costs and fees related to the item must be recognized in earnings and cannot be deferred, e.g., debt issue costs. The fair value election is irrevocable and generally made on an instrument-by-instrument basis, even if a company has similar instruments that it elects not to measure based on fair value. At the adoption date, unrealized gains and losses on existing items for which fair value has been elected are reported as a cumulative adjustment to beginning retained earnings. Subsequent to the adoption of SFAS No. 159, changes in fair value are recognized in earnings. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007 and is required to be adopted by the Company in the first quarter of fiscal 2008. The Company is currently determining whether fair value accounting is appropriate for any of its eligible items and cannot estimate the impact, if any, which SFAS No. 159 will have on its consolidated results of operations and financial condition.

Recently Adopted Accounting Pronouncements

     Effective January 1, 2007, the Company adopted FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in tax positions. FIN No. 48 requires that the Company recognize the impact of a tax position in its financial statements only if that position is more likely than not to be sustained on audit, based on the technical merits of the position. The adoption of FIN No. 48 did not result in an adjustment to the Company’s opening retained earnings since there was no cumulative effect from the change in accounting principle due to the Company maintaining a full valuation allowance against its U.S. deferred tax assets. At the date of adoption, the Company reduced its deferred tax assets and related valuation allowance by approximately $5.1 million for uncertain tax positions. As of April 1, 2007, the Company has reduced its deferred tax assets and related valuation allowance by approximately $6.8 million for uncertain tax positions. Interest and penalties related to uncertain tax positions will be reflected in income tax expense. All of the Company’s tax years remain subject to future examination by the major tax jurisdictions in which it is subject to tax.

2. Acquisition of Solexa, Inc.

     On January 26, 2007, the Company completed its acquisition of Solexa, Inc. (Solexa), a Delaware corporation, in a stock-for-stock merger transaction. The results of Solexa’s operations have been included in the Company’s consolidated financial statements since the acquisition date of January 26, 2007.

     Solexa develops genetic analysis technologies primarily in the United States and the United Kingdom. The combined Company has recently commercialized the Illumina Genome Analyzer System (renamed from the Solexa 1G Analyzer post-merger), which performs DNA sequencing based on Solexa’s proprietary reversible terminator Sequencing-by-Synthesis (SBS) chemistry and Clonal Single Molecule Array technology.

     Pursuant to the merger agreement, Solexa shareholders received 0.344 of a share of the Company’s common stock in exchange for each share of Solexa common stock held. The Company issued approximately 13.1 million shares of its common stock as consideration for this merger. In addition, certain executives at Solexa received change in control bonuses totaling approximately $7.9 million upon consummation of the merger. These bonuses were paid both in cash and in shares of Illumina common stock and were based on a percentage of the amount by which the consideration received by Solexa stockholders as a direct result of the

9

change in control exceeded the sum of $150 million plus the aggregate gross proceeds received by Solexa through sales of equity securities after the effective date of such bonus arrangement. The total number of shares issued in connection with such change in control bonuses was approximately 0.1 million shares of the Company’s common stock.

     Upon the closing of the merger on January 26, 2007, there were approximately 3.7 million shares of the Company’s restricted stock and shares issuable upon the exercise of outstanding options and warrants assumed as part of the acquisition. Total estimated merger consideration also includes approximately $75.3 million, which represents the fair market value of the vested options, warrants and restricted stock assumed. The Company also expects to recognize approximately $14.7 million of non-cash stock-based compensation expense related to unvested stock options and restricted stock at the acquisition date. This expense will be recognized beginning from the acquisition date over a weighted-average period of approximately two years. These awards were valued using the following assumptions as of January 25, 2007 (the measurement date, as discussed below):

Interest rate		4.56 — 5.05	%
Volatility		54.26	%
Expected life	0.35 — 3.98 years
Expected dividend yield		0	%

     The purchase price of the acquisition is as follows (in thousands):

Fair market value of securities issued	$	527,067
Fair market value of change of control bonuses and related taxes		8,182
Transaction costs not included in Solexa net tangible assets acquired		7,902
Fair market value of vested stock options, warrants and restricted stock assumed		75,334
Total purchase price	$	618,485

     The fair value of the Company’s shares used in determining the purchase price was based on the average of the closing price of the Company’s common stock for a range of four trading days, including two days prior to and two days subsequent to January 25, 2007, the measurement date. The measurement date was determined per the guidance in EITF No. 99-12, Determination of the Measurement Date for the Market Price of Acquirer Securities Issued in a Purchase Business Combination. Based on these closing prices, the Company estimated the fair value of its common stock to be $40.1425 per share, which equates to a total fair value of common stock issued of $527.1 million.

Purchase Price Allocation

     The Solexa purchase price was allocated to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date (January 26, 2007). The excess of the purchase price over the fair value of net assets acquired was allocated to goodwill.

10

     The Company believes the fair values assigned to the assets acquired and liabilities assumed were based on reasonable assumptions. The following table summarizes the estimated fair values of net assets acquired (in thousands):

Current assets	$	51,665
Property, plant and equipment, net		6,515
Other assets		786
Current liabilities		(13,244	)
Other long-term liabilities		(1,455	)
Net tangible assets acquired		44,267
Identifiable intangible assets (core technology and customer relationships)		24,400
In-process research and development		303,400
Goodwill		246,418
Total net assets acquired	$	618,485

     The Company’s fair value estimates for the purchase price allocation may change during the allowable allocation period, which is up to one year from the acquisition date, if additional information becomes available.

     In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, the goodwill is not amortized, but will be subject to a periodic assessment for impairment by applying a fair-value-based test. None of this goodwill is expected to be deductible for tax purposes. The Company performs its annual test for impairment of goodwill in May of each year. The Company is required to perform a periodic assessment between annual tests in certain circumstances. The Company has determined there was no impairment of the Solexa goodwill during the first quarter of 2007.

In-Process Research and Development

     The Company allocated $303.4 million of the purchase price to in-process research and development projects. In-process research and development (IPR&D) represents the valuation of acquired, to-be-completed research projects. At the acquisition date, Solexa’s ongoing research and development initiatives were primarily involved with the development of its genetic analysis platform for sequencing and expression profiling. These in-process research and development projects are composed of Solexa’s reversible terminating nucleotide biochemistry platform, referred to as sequencing-by-synthesis (SBS) biochemistry, as well as Solexa’s reagent, analyzer and genomic services related technologies, which were valued at $237.2 million, $44.2 million, $19.1 million and $2.9 million, respectively, at the acquisition date. Although these projects were approximately 95% complete at the acquisition date, they had not reached technological feasibility and had no alternative future use. Accordingly, the amounts allocated to those projects were written off in the first quarter of 2007, the period the acquisition was consummated.

     The values of the research projects were determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting net cash flows from the projects, and discounting the net cash flows to their present value. These cash flows were estimated by forecasting total revenue expected from these products and then deducting appropriate operating expenses, cash flow adjustments and contributory asset returns to establish a forecast of net cash flows arising from the in-process technology. These cash flows were substantially reduced to take into account the time value of money and the risks associated with the inherent difficulties and uncertainties given the projected stage of development of these projects at closing. Due to the nature of the forecast and the risks associated with the projected growth and profitability of the developmental projects, discount rates of 19.5% were considered appropriate for valuation of the IPR&D. The Company believes that these discount rates were commensurate with the projects’ stage of development and the uncertainties in the economic estimates described above.

     If these projects are not successfully developed, the sales and profitability of the combined company may be adversely affected in future periods. The Company believes that the foregoing assumptions used in the IPR&D analysis were reasonable at the time of the acquisition. No assurance can be given, however, that the underlying assumptions used to estimate expected project sales, development costs or profitability, or the events associated with such projects, will transpire as estimated.

Identifiable Intangible Assets

     Acquired identifiable assets include various patents that are separate and distinct from the intellectual property surrounding the SBS biochemistry platform (core technology) as well as customer relationships. These patents are held in both the U.S. and Europe. The Company valued the patents and developed technology utilizing a discounted cash flow model which uses forecasts of future royalty savings and expenses related to the intangible assets. The Company utilized a discount rate of 19.5% when preparing this model. The value of the customer relationships is the benefit derived, based upon estimated cash flows, from having a customer in place versus having to incur the time, cost and foregone cash flow required to develop or replace the customer. The amounts assigned to the core technology and customer relationships are $23.5 million and $0.9 million, respectively. The remaining useful lives of the core technology and customer relationships are ten and three years, respectively.

Goodwill

     Goodwill represents the excess of the Solexa purchase price over the sum of the amounts assigned to assets acquired less liabilities assumed. The Company believes that the acquisition of Solexa will produce the following significant benefits:

• Increased Market Presence and Opportunities. The combination of the Company and Solexa should increase the combined Company’s market presence and opportunities for growth in revenue, earnings and stockholder return. The Company believes that the Solexa technology is highly complementary to the Company’s own portfolio of products and services and will enhance the Company’s capabilities to service its existing customers, as well as accelerate the development of additional technologies, products and services. The Company believes that integrating Solexa’s capabilities with the Company’s technologies will better position the Company to address the emerging biomarker research and development and in-vitro and molecular diagnostic markets. The Company began to recognize revenue from products shipped as a result of this acquisition during the first quarter of 2007.

• Operating Efficiencies. The combination of the Company and Solexa provides the opportunity for potential economies of scale and cost savings.

     The Company believes that these primary factors support the amount of goodwill recognized as a result of the purchase price paid for Solexa, in relation to other acquired tangible and intangible assets, including in-process research and development.

     The following unaudited pro forma information shows the results of the Company’s operations for the specified reporting periods as though the acquisition had occurred as of the beginning of that period (in thousands, except per share data):

	Three Months Ended			Three Months Ended
	April 1, 2007			April 2, 2006
Revenue	$	72,205		$	29,870
Net loss	$	(2,329	)	$	(12,279	)
Basic and diluted net loss per share	$	(0.04	)	$	(0.22	)

     The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the acquisition taken place as of the beginning of the periods presented, or the results that may occur in the future. The pro forma results exclude the $303.4 million non-cash acquired IPR&D charge recorded upon the closing of the acquisition during the first quarter of 2007.

Investment in Solexa

      On November 12, 2006, the Company entered into a definitive securities purchase agreement with Solexa in which the Company invested approximately $50 million in Solexa in exchange for 5,154,639 newly issued shares of Solexa common stock in conjunction with the merger of the two companies. This investment was valued at $67.8 million as of December 31, 2006, which represented a market value of $13.15 per share of Solexa common stock. This investment was eliminated as part of the Company’s purchase accounting upon the closing of the merger on January 26, 2007.

3. Segment Information

     The Company has determined that, in accordance with SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, it operates in one segment as it only reports operating results on an aggregate basis to its chief operating decision maker of the Company.

4. Inventories

     Inventories are stated at the lower of standard cost (which approximates actual cost) or market. Inventory includes raw materials and finished goods that may be used in the research and development process and such items are expensed as consumed. Provisions for slow moving, excess and obsolete inventories are provided based on product life cycle and development plans, product expiration and quality issues, historical experience and inventory levels. The components of net inventories are as follows (in thousands):

	April 1, 2007		December 31, 2006
Raw materials	$	16,725	$	8,365
Work in process		14,640		8,907
Finished goods		4,975		2,897
	$	36,340	$	20,169

5. Goodwill and Intangible Assets

     The Company accounts for goodwill and intangibles under SFAS No. 142, Goodwill and Other Intangible Assets. As such, goodwill and other indefinite-lived intangible assets are not amortized, but are subject to annual impairment reviews, or more frequent reviews if events or circumstances indicate there may be an impairment. The Company performs its test of goodwill annually in May.

     The carrying amount of goodwill was $248.5 million as of April 1, 2007, compared to $2.1 million at December 31, 2006. The increase in goodwill was due to the acquisition of Solexa in January 2007. The $2.1 million balance at December 31, 2006 was related to the acquisition of CyVera in April 2005. This balance is included in goodwill as of April 1, 2007 and there has been no impairment of goodwill as of that date.

     Intangible assets other than goodwill are required to be separated into two categories: finite-lived and indefinite-lived. Intangible assets with finite useful lives are amortized over their estimated useful life, while intangible assets with indefinite useful lives are not amortized. The Company currently has no intangible assets with indefinite lives.

     Following is a summary of the Company’s amortizable intangible assets as of the respective balance sheet dates (in thousands):

	April 1, 2007					December 31, 2006
	Gross Carrying		Accumulated			Gross Carrying		Accumulated
	Amount		Amortization			Amount		Amortization
Acquired intangible assets:
Core technology	$	23,500	$	(392	)	$	—	$	—
Customer relationships		900		(50	)		—		—
Total acquired intangible assets		24,400		(442	)		—		—
Other intangible assets:

Total intangible assets	$	25,344	$	(1,289	)	$	944	$	(836	)

     The increase in the gross carrying amount of the Company’s amortizable intangible assets as of April 1, 2007 was due to the acquisition of Solexa in January 2007. The core technology is being amortized over a ten-year life and customer relationships are being amortized over a three-year life. The amortization of the core technology and customer relationships is excluded from product cost of revenue and is separately classified as amortization of acquired intangible assets on the condensed consolidated statement of operations.

6. Warranties

     The Company generally provides a one-year warranty on instrument systems. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses associated with system sales. This expense is recorded as a component of

13

cost of product revenue. Estimated warranty expenses associated with extended maintenance contracts are recorded as a component of cost of service and other revenue and are recognized ratably over the term of the maintenance contract.

     Changes in the Company’s warranty liability during the specified reporting period are as follows (in thousands):

Balance at December 31, 2006	$	996
Additions charged to cost of revenue		1,402
Repairs and replacements		(810	)

8. Stockholders’ Equity

     As of April 1, 2007, the Company had 53,580,525 shares of common stock outstanding, of which 4,817,328 shares were sold to employees and consultants subject to restricted stock agreements. The restricted common shares vest in accordance with the provisions of the agreements, generally over five years. All unvested shares are subject to repurchase by the Company at the original purchase price. As of April 1, 2007, 32,417 shares of common stock were subject to repurchase. In addition, the Company also issued 12,000 shares for a restricted stock award to an employee under the Company’s 2005 Stock and Incentive Plan based on service performance. These shares vest monthly over a three-year period.

     2005 Stock and Incentive Plan

     In June 2005, the stockholders of the Company approved the 2005 Stock and Incentive Plan (the 2005 Stock Plan). Upon adoption of the 2005 Stock Plan, issuance of options under the Company’s existing 2000 Stock Plan ceased. The 2005 Stock Plan initially provided that an aggregate of up to 11,542,358 shares of the Company’s common stock be reserved and available to be issued. In addition, the 2005 Stock Plan provides for an automatic annual increase in the shares reserved for issuance by the lesser of 5% of the number of outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, 1,200,000 shares or such lesser amount as determined by the Company’s board of directors. As of April 1, 2007, options to purchase 2,560,668 shares remained available for future grant under the 2005 Stock Plan.

     The aggregate intrinsic value of options outstanding and options exercisable as of April 1, 2007 was $134.6 million and $66.7 million, respectively. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the fiscal period, which was $29.30 as of March 30, 2007, and the exercise price multiplied by the number of options outstanding. Total intrinsic value of options exercised was $12.8 million for the three months ended April 1, 2007.

2000 Employee Stock Purchase Plan

     In February 2000, the board of directors and stockholders adopted the 2000 Employee Stock Purchase Plan (the Purchase Plan). A total of 6,233,713 shares of the Company’s common stock have been reserved for issuance under the Purchase Plan. The Purchase Plan permits eligible employees to purchase common stock at a discount, but only through payroll deductions, during defined offering periods.

     The price at which stock is purchased under the Purchase Plan is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. The initial offering period commenced in July 2000. In addition, beginning with fiscal 2001, the Purchase Plan provides for annual increases of shares available for issuance by the lesser of 3% of the number of outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, 1,500,000 shares or such lesser amount as determined by the Company’s board of directors. 61,787 shares were issued under the Purchase Plan during the three months ended April 1, 2007. As of April 1, 2007, there were 4,106,874 shares available for issuance under the Purchase Plan.

Warrants

     In conjunction with its acquisition of Solexa, Inc. on January 26, 2007, the Company assumed 2,244,843 warrants issued by Solexa prior to the acquisition. During the three months ended April 1, 2007, there were 350,283 warrants exercised, resulting in cash proceeds to the Company of approximately $5.3 million.

15

     A summary of the warrants outstanding as of April 1, 2007 is as follows:

Number of Shares	Exercise Price		Expiration Date
126,082	$	78.96		4/29/07
31,989	$	57.62		9/24/08

Treasury Stock

     In conjunction with its issuance of $400 million principal amount of 0.625% Convertible Senior Notes due 2014 on February 16, 2007, the Company repurchased 5.8 million shares of its outstanding common stock for approximately $201.6 million in privately negotiated transactions concurrently with the offering.

     On February 20, 2007, the Company executed a Rule 10b5-1 trading plan to repurchase up to $75.0 million of its outstanding common stock over a period of six months. During the three months ended April 1, 2007, the Company repurchased approximately 1.6 million shares of its common stock under this plan for approximately $50.0 million. In any period, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders’ equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

9. Convertible Senior Notes

     On February 16, 2007, the Company issued $400.0 million principal amount of 0.625% Convertible Senior Notes due 2014 (the Notes), which included the exercise of the initial purchasers’ option to purchase up to an additional $50.0 million aggregate principal amount of Notes. The net proceeds from the offering, after deducting the initial purchasers’ discount and offering expenses, were approximately $390.7 million. The Company will pay 0.625% interest per annum on the principal amount of the Notes, payable semi-annually in arrears in cash on February 15 and August 15 of each year, starting on August 15, 2007. The Notes mature on February 15, 2014.

     The Notes will be convertible into cash and, if applicable, shares of the Company’s common stock, $0.01 par value per share, based on an initial conversion rate, subject to adjustment, of 22.9029 shares per $1,000 principal amount of Notes (which represents an initial conversion price of approximately $43.66 per share), only in the following circumstances and to the following extent: (1) during the five business-day period after any five consecutive trading period (the measurement period) in which the trading price per note for each day of such measurement period was less than 97% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; (2) during any calendar quarter after the calendar quarter ending March 31, 2007, if the last reported sale price of the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; (3) upon the occurrence of specified events; and (4) the notes will be convertible at any time on or after November 15, 2013 through the third scheduled trading day immediately preceding the maturity date.

     In connection with the offering of the notes, the Company entered into convertible note hedge transactions (the hedge) with the initial purchasers and/or their affiliates (the counterparties) entitling the Company to purchase a maximum of 11,451,480 shares of the Company’s common stock at an initial strike price of $43.66 per share, subject to adjustment. In addition, the Company sold to these counterparties warrants to acquire a maximum of 18,322,320 shares of the Company’s common stock (the warrants) at an initial strike price of $62.87 per share, subject to adjustment. The cost of the hedge that was not covered by the proceeds from the sale of the warrants was approximately $46.6 million. The hedge is expected to reduce the potential equity dilution upon conversion of the notes if the daily volume-weighted average price per share of the Company’s common stock exceeds the strike

16

price of the hedge. The warrants could have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock during the measurement period at maturity of the warrants exceeds the strike price of the warrants.

10. Commitments and Long-Term Debt

Deferred Gain / Building Loan

     In July 2000, the Company entered into a ten-year lease to rent space in two newly constructed buildings in San Diego that are now occupied by the Company. That lease contained an option to purchase the buildings together with certain adjacent land that has been approved for construction of an additional building. The Company exercised that option and purchased the properties in January 2002 and assumed a $26.0 million, ten-year mortgage on the property at a fixed interest rate of 8.36%. The Company made monthly payments of $208,974, representing interest and principal, through August 2004.

     In June 2004, the Company entered into a conditional agreement to sell its land and buildings for $42.0 million and to lease back such property for an initial term of ten years. The sale was completed in August 2004 at which time the lease was signed. After the repayment of the remaining $25.2 million debt and other related transaction expenses, the Company received $15.5 million in net cash proceeds. The Company removed the land and net book value of the buildings of $36.9 million from its balance sheet, deferred the resulting $3.7 million gain on the sale of the property, and is amortizing the deferred gain over the ten-year lease term in accordance with SFAS No. 13, Accounting for Leases.

Operating Leases

     In August 2004, the Company entered into a ten-year lease for its San Diego facility after the land and building were sold (as discussed above). Under the terms of the lease, the Company paid a $1.9 million security deposit and monthly rent is set at $318,643 for the first year with an annual increase of 3% in each subsequent year through 2014. The current monthly rent under this lease is $338,048. On February 14, 2007, the Company extended this lease. The terms of the new lease provide for monthly rent increases each year to a maximum of $504,710 per month during the last year of the lease, which is now 2023. Under the terms of the new lease, approximately $1.0 million of the original $1.9 million security deposit was refunded to the Company during the three months ended April 1, 2007. The Company has the option to extend the term of the lease for three additional five-year periods. In accordance with SFAS No. 13, the Company records rent expense on a straight-line basis and the resulting deferred rent is included in other long-term liabilities in the accompanying consolidated balance sheet.

     On February 14, 2007, the Company also entered into an operating lease agreement with BioMed Realty Trust, Inc. (BioMed) to expand into a new office building BioMed will build in San Diego, California. The new building will be used for research and development, manufacturing and administrative purposes. The lease expires 15 years from the date the first phase is occupied (October 1, 2008), subject to the Company’s right to extend the term for up to three additional five-year periods. The Company will begin paying rent once the first phase is occupied, at an initial rate of $114,425 per month, which will increase as the remaining two phases are occupied, based on an initial monthly base rent of $2.80 per rentable square foot. The monthly rent will increase by 5% every 24 months.

     As of April 1, 2007, the Company also leased an office and laboratory facility in Connecticut, additional office, distribution and storage facilities in San Diego, and four foreign facilities located in Japan, Singapore, China and the Netherlands under non-cancelable operating leases that expire at various times through June 2011. These leases contain renewal options ranging from one to five years.

     As part of our acquisition of Solexa on January 26, 2007, we assumed a non-cancelable operating lease for facilities in Hayward, California. One of the buildings is utilized for administrative operations, research and development, as well as genomic services and instrument production. The remaining space may be developed and occupied in phases, depending on growth. The Hayward lease runs through December 2008. We have an option to extend the lease for an additional five-year period, subject to certain conditions. We also lease a facility in Little Chesterford, United Kingdom, which is occupied by Solexa Limited, our wholly-owned subsidiary, which expires in July 2008.

11. Legal Proceedings

     The Company has incurred substantial costs in defending itself against patent infringement claims, and expects to devote substantial financial and managerial resources to protect its intellectual property and to defend against the claims described below as well as any future claims asserted against it.

Affymetrix Litigation

     On July 26, 2004, Affymetrix, Inc. (Affymetrix) filed a complaint in the U.S. District Court for the District of Delaware alleging that the use, manufacture and sale of the Company’s BeadArray products and services, including the Company’s Array Matrix and BeadChip products, infringe six Affymetrix patents. Affymetrix seeks an injunction against the sale of any products that may ultimately be determined to infringe these patents, unspecified monetary damages, interest and attorneys’ fees. On September 15, 2004, the Company filed its answer to Affymetrix’ complaint, seeking declaratory judgments from the court that it does not infringe the Affymetrix patents and that such patents are invalid, and the Company filed counterclaims against Affymetrix for unfair competition and interference with actual and prospective economic advantage.

     On February 15, 2006, the court allowed the Company to file its first amended answer and counterclaims, adding allegations of inequitable conduct with respect to all six asserted Affymetrix patents, violation of Section 2 of the Sherman Act, and unclean hands. In March 2006, Affymetrix notified the Company of its decision to drop one of the six patents from the suit, and of its intention to assert infringement of certain additional claims of the remaining five patents. On June 30, 2006, the court dismissed the patent Affymetrix had sought to withdraw from the suit. Both parties filed summary judgment motions by the July 14, 2006 deadline established by the court, and all such motions have now been stayed or denied. On August 16, 2006, the court issued a ruling on the Markman (claim construction) hearing it held on April 20, 2006. At the parties’ request, the trial was rescheduled to March 5, 2007 from October 16, 2006. In a February 2007 pre-trial order, the court established a multi-phase trial structure. The court explained that it decided to address the Company’s defenses of invalidity and enforceability of the patents-in-suit, as well as the Company’s claims for unfair competition and antitrust violations, in subsequent trials.

     The first phase, which began on March 5, 2007, addressed the issues of infringement and damages. On March 13, 2007, the jury returned a verdict finding infringement of the five patents asserted by Affymetrix. That finding was made without consideration of the validity and enforceability of these five Affymetrix patents. The jury awarded retroactive damages for certain product sales prior to the end of 2005 at a royalty rate of 15% in an amount of approximately $16.7 million. This first-phase verdict remains subject to the Company’s post-trial motions and appeals. A judgment on this verdict has not been entered in the case and the Company does not believe such judgment, along with any final damages award, will be entered until after the subsequent phases of the trial are completed.

     To the extent the Company succeeds in proving some or all of Affymetrix’ patents invalid or unenforceable, the damages amount may be reduced, including to zero, and the court may require a new trial on the damages amount. If the Company is not successful in the subsequent phases, damages may be assessed, in addition to the $16.7 million amount, on post-2005 sales of the Company’s products that were found to infringe the Affymetrix patents. Affymetrix has also asserted that the Company’s products launched post-2005 infringe these patents, but these other products were not at issue in the prior jury trial, and the court has yet to indicate how the issues of infringement and potential damages will be judged for these other products. In addition, Affymetrix is contending that the Company’s infringement was willful, and if a jury finds the Company’s infringement to be willful, the judge will have the discretion to increase any damage award by up to three times. Affymetrix has also contended that it should be awarded its attorney’s fees and pre-judgment interest on any damages award.

     The second phase of the trial, which will include trial as to the validity of the Affymetrix patents being asserted, will be tried before a different jury and is expected to be scheduled later in 2007. The Company’s defense of inequitable conduct, and its counterclaims for tortious interference and unfair competition by Affymetrix, will be addressed in a third phase of the trial. In order for Affymetrix to prevail in the case and receive a judgment in its favor, the patent claims found to have been infringed must also be found to be valid and enforceable in the remaining phases of the trial, and then such findings must be upheld on appeal. The Company believes it has prior art that pre-dates and invalidates the Affymetrix patents. The Company is also claiming that the inventors or their agents engaged in inequitable conduct before the United States Patent and Trademark Office in connection with the prosecution of one or more of the patents in-suit, and the Company believes that this conduct should render the affected patents unenforceable.

18

     In the second and third phases of the trial, the Affymetrix patents will be presumed to be valid and the Company will have the burden of proving, by clear and convincing evidence, that the patents are invalid and/or unenforceable. To the extent the Company is unable to prove invalidity or unenforceability, the court will likely enter a judgment against the Company and assess damages. Affymetrix is also seeking an injunction to prevent the Company from making, selling or offering to sell products that infringe patents that are found valid and enforceable.

     Although the Company believes that it has strong defenses to Affymetrix’ patent claims, the results of litigation are difficult to predict and no assurance can be given that the Company will succeed in proving the patents were not infringed, or are invalid or unenforceable. As discussed above, the judge overseeing the case has discretion over how and when issues in the case will be tried, and over the granting and scope of any injunction against the Company. Any damages award or injunction would be subject to appeal and the Company will carefully consider an appeal at the appropriate time. In such a case, if the Company chooses to appeal, the Company would likely be required to post a bond or provide other security for some or the entire amount of the final damages award during the appeal, and such amount may be material.

     The Company has analyzed the potential for a loss from this litigation in accordance with SFAS No. 5, Accounting for Contingencies. Due to the Company’s beliefs about its position in the case, and because the Company is unable to reasonably estimate the amount of loss the Company would incur if the Company does not prevail, the Company has not recorded a reserve for contingent loss. Should the Company ultimately lose the lawsuit, such result could have a material adverse effect on its consolidated results of operations for the period in which the loss is recorded.

Dr. Anthony W. Czarnik v. Illumina, Inc.

     On June 15, 2005, Dr. Anthony Czarnik, a former employee, filed suit against the Company in the U.S. District Court for the District of Delaware seeking correction of inventorship of certain of the Company’s patents and patent applications, and alleging that the Company committed inequitable conduct and fraud in not naming him as an inventor. Dr. Czarnik seeks an order requiring the Company and the U.S. Patent and Trademark Office to correct the inventorship of certain of the Company’s patents and patent applications by adding Dr. Czarnik as an inventor, a judgment declaring certain of the Company’s patents and patent applications unenforceable, unspecified monetary damages and attorney’s fees. On August 4, 2005, the Company filed a motion to dismiss the complaint for lack of standing and failure to state a claim. While this motion was pending, Dr. Czarnik filed an amended complaint on September 23, 2005. On October 7, 2005, the Company filed a motion to dismiss the amended complaint for lack of standing and failure to state a claim. On July 13, 2006, the court granted the Company’s motion to dismiss the counts of Dr. Czarnik’s complaint dealing with correction of inventorship in pending applications and inequitable conduct. On July 27, 2006, the Company filed its answer to the two remaining counts of the amended complaint (correction of inventorship in issued patents, and fraud). On March 28, 2007, the court issued a Scheduling Order in which it contemplates holding a claim construction hearing in January 2008 if it deems claim construction to be necessary. A trial date has yet to be set for this case. The Company believes it has meritorious defenses against these claims.

12. Collaborative Agreements

deCODE genetics

     In May 2006, the Company and deCODE genetics, ehf. (deCODE) executed a Joint Development and Licensing Agreement (the Development Agreement). Pursuant to the Development Agreement, the parties agreed to collaborate exclusively to develop, validate and commercialize specific diagnostic tests for variants in genes involved in three disease-related pathways: the gene-encoding leukotriene A4 hydrolase, linked to heart attack; the gene-encoding transcription factor 7-like 2 (TCF7L2), linked to type 2 diabetes; and the gene-encoding BARD1, linked to breast cancer. The Company and deCODE are developing diagnostic tests based on these variants for use on the Company’s BeadXpress system.

     Under the agreement, the Company will be responsible for the manufacturing, marketing and selling of the diagnostic products. The companies will share the development costs of these products and split the profits from sales of the diagnostics tests. The Development Agreement may be terminated as to a particular product under development if one party decides to discontinue funding the development of that product, and may be terminated in whole by either party if the other party commits an uncured material breach, files for bankruptcy or becomes insolvent. Under a separate supply agreement, the Company installed instrumentation at deCODE that will enable deCODE to perform whole genome association studies on up to 100,000 samples using the Company’s Sentrix HumanHap300 BeadChips and associated reagents. The Company has deferred approximately $2.0 million of revenue for instruments installed during the third quarter of 2006 under guidance provided by SFAS No. 48, Revenue

19

Recognition When Right of Return Exists. This amount is classified as a long-term liability as of April 1, 2007. The Company has also deferred approximately $1.3 million of costs related to product shipments to deCODE, which are classified as a long-term asset as of April 1, 2007.

13. Investment in Genizon BioSciences Inc.

     In January 2006, Genizon BioSciences Inc. (Genizon), a Canadian company focused on gene discovery, purchased from the Company approximately $1.9 million in equipment and committed to purchase an additional $4.3 million in consumables. Genizon is using Illumina’s HumanHap300 BeadChip along with the Infinium^® assay to perform whole-genome association studies involving thousands of members of the Quebec Founder Population. The goal of the studies is to provide understanding of the genetic origins and mechanisms of common diseases which may then lead to possible drug targets.

     In March 2006, the Company entered into a Subscription Agreement for Secured Convertible Debentures with Genizon. Pursuant to the agreement, the Company purchased a secured convertible debenture (the debenture) of Genizon and certain warrants for CDN$3.5 million (approximately U.S. $3.0 million).

     The debenture is convertible, automatically upon the occurrence of a “liquidity event,” as defined in the debenture, into Class H Preferred Shares of Genizon. Upon the occurrence of certain events, Illumina may be entitled to receive additional shares of Genizon’s Class H Preferred Shares. The debenture matures two years from issuance and bears interest, payable semiannually, at a rate of 5% per annum for the first year and 12.5% per annum for the second year. Unless the debenture is converted before maturity, 112.5% of the principal amount of the debenture is due upon maturity. Illumina also received warrants to purchase 226,721 shares of Genizon Class H Preferred Shares at an exercise price of $1.5437 per share.

     As of April 1, 2007, the debenture was recorded at face value, which is the fair value, and is classified in accordance with SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, as an available-for-sale security.

     The Company concluded that the purchase of the debenture and the concurrent purchase by Genizon of Illumina’s products are “linked” transactions under guidance contained in EITF No. 00-21. Since the transactions are considered “linked,” the Company deferred approximately $3.0 million of revenue (the face value of the Debentures) in the first quarter of 2006, related to the Genizon product shipments. The deferred revenue is classified as a short-term liability as of April 1, 2007. This amount is expected to remain in deferred revenue until Genizon settles the Debenture in cash or when a liquidity event occurs that generates cash or a security that is readily convertible into cash. The Company has deferred approximately $1.1 million of costs related to product shipments to Genizon, in the first quarter of 2006, which is classified as an other current asset as of April 1, 2007. All Genizon shipments that generate revenue over the face value of the debenture will be evaluated under the Company’s revenue recognition policy, which is outlined in Note 1.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

     This discussion and analysis should be read in conjunction with our financial statements and accompanying notes included in this Quarterly Report on Form 10-Q and the financial statements and notes thereto for the year ended December 31, 2006 included in our Annual Report on Form 10-K. Operating results are not necessarily indicative of results that may occur in future periods.

     The discussion and analysis in this Quarterly Report on Form 10-Q contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations and intentions. Words such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” intend,” “may,” “plan,” “potential,” “predict,” “project,” or similar words or phrases, or the negatives of these words, may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. Examples of forward-looking statements include, among others, statements regarding the costs and outcome of our litigation with Affymetrix, the integration of Solexa’s technology with our existing technology, the commercial launch of new products, including products based on Solexa’s and our VeraCode technologies, and the duration which our existing cash and other resources is expected to fund our operating activities.

     Forward-looking statements are subject to known and unknown risks and uncertainties and are based on potentially inaccurate assumptions that could cause actual results to differ materially from those expected or implied by the forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed in the subsection entitled “Item 1A. Risk Factors.” below as well as those discussed elsewhere. Accordingly, you should not unduly rely on these forward-looking statements, which speak only as of the date of this Quarterly Report. We undertake no obligation to publicly revise these forward-looking statements to reflect circumstances or events after the date of this Quarterly Report or to reflect the occurrence of unanticipated events. You should, however, review the factors and risks we describe in the reports we file from time to time with the Securities and Exchange Commission (SEC).

Overview

     We are a leading developer, manufacturer and marketer of next-generation life science tools and integrated systems for the large scale analysis of genetic variation and biological function. Using our proprietary technologies, we provide a comprehensive line of products and services that currently serve the sequencing, genotyping and gene expression markets, and we expect to enter the market for molecular diagnostics. Our customers include leading genomic research centers, pharmaceutical companies, academic institutions, clinical research organizations and biotechnology companies. Our tools provide researchers around the world with the performance, throughput, cost effectiveness and flexibility necessary to perform the billions of genetic tests needed to extract valuable medical information from advances in genomics and proteomics. We believe this information will enable researchers to correlate genetic variation and biological function, which will enhance drug discovery and clinical research, allow diseases to be detected earlier and permit better choices of drugs for individual patients.

Our Technologies

BeadArray Technology

     We have developed a proprietary array technology that enables the large-scale analysis of genetic variation and biological function. Our BeadArray technology combines microscopic beads and a substrate in a simple proprietary manufacturing process to produce arrays that can perform many assays simultaneously. Our BeadArray technology provides a unique combination of high throughput, cost effectiveness, and flexibility. We believe that these features have enabled our BeadArray technology to become a leading platform for the emerging high-growth market of SNP genotyping and expect they will enable us to become a key player in the gene expression market.

VeraCode Technology

     The BeadArray technology is most effective in applications which require mid- to high levels of multiplexing from low to high levels of throughput. Multiplexing refers to the number of individual pieces of information that are simultaneously extracted from one sample. We believe the molecular diagnostics market will require systems which are extremely high throughput and cost effective in the mid- to low-multiplex range. To address this market, we acquired our VeraCode technology through the acquisition of CyVera Corporation in April 2005. We began shipping the BeadXpress system, which uses the VeraCode technology, during the first quarter of 2007, along with several assays for the system.

21

Sequencing Technology

     Our DNA sequencing technology, acquired as part of the Solexa, Inc. (Solexa) merger that was completed on January 26, 2007, is based on use of our sequencing-by-synthesis (SBS) biochemistry. We believe that this technology, which can potentially generate over a billion bases of DNA sequence from a single experiment with a single sample preparation, will dramatically reduce the cost, and improve the practicality, of human resequencing relative to conventional technologies.

Product Developments

     During the first quarter of 2007, we announced the following new product developments:

• High-throughput DNA methylation profiling on the BeadArray platform. This technology is capable of surveying up to 1,536 methylation sites across 96 samples simultaneously. By pairing our BeadArray platform with the GoldenGate assay approach, researchers have the ability to perform genome-wide methylation profiling across multiple areas such as cancer and human embryonic stem cell research. The GoldenGate Methylation Cancer Panel I, the first standard panel, covers 1,505 methylation sites over 800 cancer genes. Shipments of the GoldenGate Methylation Cancer Panel I began during the first quarter of 2007

• BeadXpress System. The BeadXpress Reader System is a high-throughput, dual-color laser detection system that enables scanning of a broad range of multiplexed assays developed using the VeraCode digital microbead technology. Shipments of the BeadXpress System began during the first quarter of 2007.

• Illumina Genome Analyzer. This product can generate more than one billion bases of data in a single run using a massively parallel sequencing approach. The system leverages Solexa sequencing technology and novel reversible terminator chemistry, optimized to achieve unprecedented levels of cost effectiveness and throughput. Shipments of the Illumina Genome Analyzer began during the first quarter of 2007.

• Human 1M BeadChip. This product is expected to combine an unprecedented level of content for both whole-genome and copy number variation (CNV) analysis, along with additional unique, high-value genomic regions of interest — all on a single microarray chip.

• Human 450S BeadChip. This product is expected to enable customers using our HumanHap550 BeadChip to further extend their genetic studies to include the one million content level.

• HumanCNV370-Duo BeadChip. The HumanCNV370-Duo is expected to enable researchers to analyze two samples simultaneously and access novel content for detecting disease-relevant CNV regions.

• Custom methylation application. Custom-content design provides researchers with the flexibility to perform genome-wide methylation profiling specific to individual study goals. Joining our GoldenGate Methylation Cancer Panel I, investigators will have the option to select their favorite genes or gene regions to cost-effectively survey up to 1,536 methylation sites of choice across 96 samples simultaneously.

Critical Accounting Policies and Estimates

General

     Our discussion and analysis of our financial condition and results of operations is based upon our condensed unaudited consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of financial statements requires that management make estimates, assumptions and judgments with respect to the application of accounting policies that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosures of contingent assets and liabilities. Actual results could differ from those estimates. Our significant accounting policies are described in Note 1 to our unaudited condensed consolidated financial statements. Certain accounting policies are deemed critical if 1) they require an accounting estimate to be made based on assumptions that were highly uncertain at the time the estimate was made, and

22

2) changes in the estimate that are reasonably likely to occur, or different estimates that we reasonably could have used would have a material effect on our unaudited condensed consolidated financial statements.

     Management has discussed the development and selection of these critical accounting policies with the Audit Committee of our Board of Directors, and the Audit Committee has reviewed the disclosure. In addition, there are other items within our financial statements that require estimation, but are not deemed critical as defined above. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of the unaudited condensed consolidated financial statements.

Revenue Recognition

     Our revenue is generated primarily from the sale of products and services. Product revenue consists of sales of arrays, reagents, instrumentation and oligonucleotides (oligos), which are short pieces of DNA. Service and other revenue consists of revenue received for performing genotyping services, extended warranty sales and revenue earned from milestone payments.

     We recognize revenue in accordance with the guidelines established by SEC Staff Accounting Bulletin (SAB) No. 104. Under SAB No. 104, revenue cannot be recorded until all of the following criteria have been met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the seller’s price to the buyer is fixed or determinable; and collectibility is reasonably assured. All revenue is recorded net of any applicable allowances for returns or discounts.

     Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided no significant obligations remain and collection of the receivables is reasonably assured. Revenue from the sale of instrumentation is recognized when earned, which is generally upon shipment. However, in the case of BeadLabs, revenue is recognized upon the completion of installation, training and customer acceptance. Revenue for genotyping services is recognized when earned, which is generally at the time the genotyping analysis data is delivered to the customer or as specific milestones are achieved.

     In order to assess whether the price is fixed and determinable, we ensure there are no refund rights. If payment terms are based on future performance or a right of return exists, we defer revenue recognition until the price becomes fixed and determinable. We assess collectibility based on a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection of a payment is not reasonably assured, revenue recognition is deferred until the time collection becomes reasonably assured, which is generally upon receipt of payment. Changes in judgments and estimates regarding application of SAB No. 104 might result in a change in the timing or amount of revenue recognized.

     Sales of instrumentation generally include a standard one-year warranty. We also sell separately priced maintenance (extended warranty) contracts, which are generally for one or two years, upon the expiration of the initial warranty. Revenue for extended warranty sales is recognized ratably over the term of the extended warranty period. Reserves are provided for estimated product warranty expenses at the time the associated revenue is recognized. If we were to experience an increase in warranty claims or if costs of servicing our warrantied products were greater than our estimates, gross margins could be adversely affected.

     While the majority of our sales agreements contain standard terms and conditions, we do enter into agreements that contain multiple elements or non-standard terms and conditions. Emerging Issues Task Force (EITF) No. 00-21, Revenue Arrangements with Multiple Deliverables, provides guidance on accounting for arrangements that involve the delivery or performance of multiple products, services, or rights to use assets within contractually binding arrangements. Significant contract interpretation is sometimes required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, and if so, how the price should be allocated among the deliverable elements, when to recognize revenue for each element, and the period over which revenue should be recognized. We recognize revenue for delivered elements only when we determine that the fair values of undelivered elements are known and there are no uncertainties regarding customer acceptance.

     Research revenue consists of amounts earned under research agreements with government grants, which is recognized in the period during which the related costs are incurred.

Allowance for Doubtful Accounts

     We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We evaluate the collectibility of our accounts receivable based on a combination of factors. We regularly

23

analyze customer accounts, review the length of time receivables are outstanding and review historical loss rates. If the financial condition of our customers were to deteriorate, additional allowances could be required.

Inventory Valuation

     We record adjustments to inventory for potentially excess, obsolete or impaired goods in order to state inventory at net realizable value. We must make assumptions about future demand, market conditions and the release of new products that will supercede old ones. We regularly review inventory for excess and obsolete products and components, taking into account product life cycle and development plans, product expiration and quality issues, historical experience and our current inventory levels. If actual market conditions are less favorable than anticipated, additional inventory adjustments could be required.

Contingencies

     We are subject to legal proceedings primarily related to intellectual property matters. Based on the information available at the balance sheet dates and through consultation with our legal counsel, we assess the likelihood of any adverse judgments or outcomes of these matters, as well as the potential ranges of probable losses. If losses are probable and reasonably estimable, we will record a liability in accordance with Statement of Financial Accounting Standards (SFAS) No. 5, Accounting for Contingencies. Currently, we have no such liabilities recorded. This may change in the future depending upon new developments in each matter.

Goodwill and Intangible Asset Valuation

     The purchase method of accounting for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including in-process research and development (IPR&D). Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to at least annual impairment tests. The amounts and useful lives assigned to other acquired intangible assets impact future amortization, and the amount assigned to IPR&D is expensed immediately. Determining the fair values and useful lives of intangible assets especially requires the exercise of judgment. While there are a number of different acceptable generally accepted valuation methods to estimate the value of intangible assets acquired, we primarily use the discounted cash flow method. This method requires significant management judgment to forecast the future operating results used in the analysis. In addition, other significant estimates are required such as residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. These judgments can significantly affect our net operating results.

     SFAS No. 142, Goodwill and Other Intangible Assets, requires that goodwill and certain intangible assets be assessed for impairment using fair value measurement techniques. If the carrying amount of a reporting unit exceeds its fair value, then a goodwill impairment test is performed to measure the amount of the impairment loss, if any. The goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as in a business combination. Determining the fair value of the implied goodwill is judgmental in nature and often involves the use of significant estimates and assumptions. These estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized and also the magnitude of any such charge. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. These approaches use significant estimates and assumptions, including projection and timing of future cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, determination of appropriate market comparables, and determination of whether a premium or discount should be applied to comparables. It is reasonably possible that the plans and estimates used to value these assets may be incorrect. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges. As of April 1, 2007, we had $248.5 million of goodwill. This goodwill is reported as a separate line item in the balance sheet. We perform our test of goodwill annually in May. We have determined there has been no impairment of goodwill as of April 1, 2007.

Stock-Based Compensation

     We account for stock-based compensation in accordance with SFAS No. 123R, Share-Based Payment. Under the provisions of SFAS No. 123R, stock-based compensation cost is estimated at the grant date based on the award’s fair-value as calculated by the Black-Scholes-Merton (BSM) option-pricing model and is recognized as expense over the requisite service period. The BSM model requires various highly judgmental assumptions including volatility, forfeiture rates, and expected option life. If any of these

24

assumptions used in the BSM model change significantly, stock-based compensation expense may differ materially in the future from that recorded in the current period.

Income Taxes

     In accordance with SFAS No. 109, Accounting for Income Taxes, the provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction by jurisdiction basis, and includes a review of all available positive and negative evidence. As of April 1, 2007 we have maintained a full valuation allowance against all of our U.S. deferred tax assets, and certain foreign deferred tax assets, since we have not met the “more likely than not” threshold required under SFAS No. 109.

     Due to the adoption of SFAS No. 123 (revised 2004), Share-Based Payment, we recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, we follow the with-and-without approach excluding any indirect effects of the excess tax deductions. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us.

     Effective January 1, 2007, we adopted FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in tax positions. FIN No. 48 requires that we recognize the impact of a tax position in our financial statements only if that position is more likely than not to be sustained on audit, based on the technical merits of the position. The adoption of FIN No. 48 did not result in an adjustment to our opening retained earnings since there was no cumulative effect from the change in accounting principle due to our maintaining a full valuation allowance against our U.S. deferred tax assets. At the date of adoption, we reduced our deferred tax assets and related valuation allowance by approximately $5.1 million for uncertain tax positions. As of April 1, 2007, we have reduced our deferred tax assets and related valuation allowance by approximately $6.8 million for uncertain tax positions. Interest and penalties related to uncertain tax positions will be reflected in income tax expense. All of our tax years remain subject to future examination by the major tax jurisdictions in which we are subject to tax.

Three Months Ended April 1, 2007 and April 2, 2006

     Our fiscal year consists of 52 or 53 weeks ending the Sunday closest to December 31, with quarters of 13 or 14 weeks ending the Sunday closest to March 31, June 30, and September 30. The three months ended April 1, 2007 and April 2, 2006 were both 13 weeks.

Revenue

	Three Months Ended
	April 1,		April 2,		Percentage
	2007		2006		Change
	(in thousands)
Product revenue	$	61,266	$	23,261		163	%
Service and other revenue		10,761		5,267		104	%
Research revenue		123		574		(79	)%
Total revenue	$	72,150	$	29,102		148	%

     Total revenue for the three months ended April 1, 2007 and April 2, 2006 was $72.2 million and $29.1 million, respectively. This represents an increase of $43.0 million, or 148%, compared to the three months ended April 2, 2006.

     Product revenue increased to $61.3 million for the three months ended April 1, 2007 from $23.3 million for the three months ended April 2, 2006. The increase resulted primarily from higher consumable sales, as well as sales of the Illumina Genome

26

Analyzer, which was introduced during the first quarter of 2007. Growth in consumable revenue was primarily attributable to a significant demand for our Infinium products, which we began selling during the second quarter of 2006. In addition, growth in consumable revenue can be attributed to the growth in our installed base of BeadArray Readers. We expect to see continued growth in product revenue, which can be partially attributed to the launch of several new products, including the Illumina Genome Analyzer and BeadXpress System, both introduced during the first quarter of 2007, as well as the growth of our installed base of instruments.

     Service and other revenue increased to $10.8 million for the three months ended April 1, 2007 from $5.3 million for the three months ended April 2, 2006. The increase in service and other revenue is primarily due to the completion of several significant Infinium and iSelect custom SNP genotyping service contracts. We expect sales from SNP genotyping services contracts to fluctuate on a yearly and quarterly basis, depending on the mix and number of contracts that are completed. The timing of completion of a SNP genotyping services contract is highly dependent on the customer’s schedule for delivering the SNPs and samples to us.

     Government grants and other research funding decreased to $0.1 million for the three months ended April 1, 2007 from $0.6 million for the three months ended April 2, 2006. We do not expect research revenue to be a material component of our revenue going forward.

Cost of Product and Service and Other Revenue

	Three Months Ended
	April 1,		April 2,		Percentage
	2007		2006		Change
	(in thousands)
Cost of product revenue	$	21,815	$	7,676		184	%
Cost of service and other revenue		3,305		1,617		104	%
Total cost of product and service and other revenue	$	25,120	$	9,293		170	%

     Cost of product and service and other revenue represents manufacturing costs incurred in the production process, including component materials, assembly labor and overhead, installation, warranty, packaging and delivery costs, as well as costs associated with performing genotyping services on behalf of our customers. Costs related to research revenue are included in research and development expense. Cost of product revenue increased to $21.8 million for the three months ended April 1, 2007, compared to $7.7 million for the three months ended April 2, 2006, primarily driven by higher consumable and instrument sales. Cost of product revenue for the three months ended April 1, 2007 and April 2, 2006 included stock-based compensation expenses totaling $0.9 million and $0.2 million, respectively. Gross margin on product revenue decreased to 64.4% for the three months ended April 1, 2007, compared to 67.0% for the three months ended April 2, 2006. The decrease in gross margin percentage is primarily due to the additional expense of $0.6 million for the amortization of inventory revaluation costs related to our acquisition of Solexa in January 2007, unfavorable product mix and the increase in stock-based compensation charges. The inventory revaluation costs decreased our gross margin by 105 basis points in 2007 compared to 2006. The impact of stock-based compensation charges decreased our gross margin by 59 basis points in 2007 compared to 2006.

     Cost of service and other revenue increased to $3.3 million for the three months ended April 1, 2007, compared to $1.6 million for the three months ended April 2, 2006, primarily due to higher service revenue. Cost of service and other revenue for the three months ended April 1, 2007 and April 2, 2006 included stock-based compensation expenses totaling $0.1 million in each period. Gross margin on service and other revenue was 69.3% for the three months ended April 1, 2007 and April 2, 2006.

     We expect product mix to continue to affect our future gross margins. However, we expect our market to continue to be increasingly price competitive and our margins may fluctuate from year to year and quarter to quarter.

Research and Development Expenses

	Three Months Ended
	April 1,		April 2,		Percentage
	2007		2006		Change
	(in thousands)
Research and development	$	15,956	$	8,216		94	%

     Our research and development expenses consist primarily of salaries and other personnel-related expenses, laboratory supplies and other expenses related to the design, development, testing and enhancement of our products. We expense our research and development expenses as they are incurred.

     Research and development expenses increased $7.7 million to $16.0 million for the three months ended April 1, 2007, compared to $8.2 million for the three months ended April 2, 2006. Approximately $5.4 million of the increase is due to higher research and development expenses associated with our recent acquisition of Solexa that closed on January 26, 2007. Costs to support our Oligator technology platform and BeadArray research activities increased approximately $1.8 million for the three months ended April 1, 2007, compared to the three months ended April 2, 2006 primarily due to an overall increase in personnel-related expenses, as well as increased project spending. In addition, stock-based compensation expense increased approximately $0.9 million compared to the three months ended April 2, 2006. These increases were partially offset by a decrease of $0.4 million in research and development expenses related to the VeraCode technology. We began shipping our BeadXpress System, which is based on our VeraCode technology, during the first quarter of 2007. As a result, the related research and development expenses have decreased.

     We believe a substantial investment in research and development is essential to remaining competitive and expanding into additional markets. Accordingly, we expect our research and development expenses to increase in absolute dollars as we expand our product base and integrate the operations of Solexa into our business.

Selling, General and Administrative Expenses

	Three Months Ended
	April 1,		April 2,		Percentage
	2007		2006		Change
	(in thousands)
Selling, general and administrative	$	23,633	$	12,134		95	%

     Our selling, general and administrative expenses consist primarily of personnel costs for sales and marketing, finance, human resources, business development, legal and general management, as well as professional fees, such as expenses for legal and accounting services. Selling, general and administrative expenses increased to $23.6 million for the three months ended April 1, 2007, compared to $12.1 million for the three months ended April 2, 2006. Selling, general and administrative expenses for the three months ended April 2, 2007 and April 2, 2006 included stock-based compensation expenses totaling $4.8 million and $1.9 million, respectively.

     Sales and marketing expenses increased $4.0 million for the three months ended April 1, 2007, compared to the three months ended April 2, 2006. The increase is primarily due to increases of $3.1 million attributable to personnel-related expenses to support the growth of our business, $0.7 million of stock-based compensation expense and $0.2 million attributable to other non-personnel-related costs, mainly sales and marketing activities for our existing and new products. General and administrative expenses increased $7.5 million during the three months ended April 1, 2007, compared to the three months ended April 2, 2006, due to increases of $3.0 million in outside legal costs primarily related to the Affymetrix litigation, $2.2 million of stock-based compensation expense, $1.6 million in personnel-related expenses associated with the growth of our business and $0.7 million in other outside services, primarily due to increases in consulting fees.

     We expect our selling, general and administrative expenses to increase in absolute dollars as we expand our staff, add sales and marketing infrastructure, incur increased litigation costs and incur additional costs to support the growth in our business.

Interest and Other Income, Net

	(in thousands)
Interest and other income, net	$	2,722	$	568		379	%

     Interest income on our cash and cash equivalents and investments was $3.2 million for the three months ended April 1, 2007, compared to $0.5 million for the three months ended April 2, 2006. The increase is primarily due to higher cash balances from the proceeds of our May 2006 stock offering, our February 2007 convertible debt offering and operating cash flow, as well as higher effective interest rates on our cash equivalents and short-term investments. This increase was partially offset by approximately $0.5 million of interest expense mainly related to our convertible debt offering in February 2007.

Provision for Income Taxes

	Three Months Ended
	April 1,		April 2,		Percentage
	2007		2006		Change
	(in thousands)
Provision for income taxes	$	4,397	$	131		3256	%

     The provision for income taxes was approximately $4.4 million for the three months ended April 1, 2007, up from $0.1 million for the three months ended April 2, 2006. For the three months ended April 1, 2007, the provision consists of federal, state, and foreign income tax expenses. For the three months ended April 2, 2006, the provision for income taxes consisted of income tax expense related to foreign operations.

     As of January 1, 2007, we had net operating loss carryforwards for federal and state tax purposes of approximately $76.4 million and $39.1 million, respectively, which begin to expire in 2022 and 2013, respectively, unless previously utilized. In addition, we also had U.S. federal and state research and development tax credit carryforwards of approximately $6.4 million and $6.3 million, respectively, which begin to expire in 2018 and 2019, respectively, unless previously utilized. As result of the Solexa acquisition on January 26, 2007, we obtained additional net operating loss carryforwards for federal and state tax purposes of approximately $27.9 million and $70.2 million, respectively, which begin to expire in 2025 and 2015, respectively, unless previously utilized. To the extent these assets are recognized, the adjustment will be applied first to reduce to zero any goodwill related to the acquisition, and then as a reduction to the income tax provision.

     Pursuant to Section 382 and 383 of the Internal Revenue Code, utilization of our net operating losses and credits may be subject to annual limitations in the event of any significant future changes in our ownership structure. These annual limitations may result in the expiration of net operating losses and credits prior to utilization. Previous limitations due to Section 382 and 383 have been reflected in the deferred tax assets as of April 1, 2007.

     Based upon the available evidence as of April 1, 2007, we are not able to conclude it is more likely than not the remaining deferred tax assets in the U.S. or certain foreign jurisdictions will be realized. Therefore, we have recorded a full valuation allowance against all of our U.S. deferred tax assets and certain foreign deferred tax assets of approximately $92.5 million, and $15.2 million, respectively.

Liquidity and Capital Resources

Cashflow (in thousands)

	Three Months Ended
	April 1, 2007			April 2, 2006
Net cash provided by operating activities	$	14,643		$	2,360
Net cash used in investing activities		(34,410	)		(7,228	)

Effect of foreign currency translation on cash and cash equivalents		(40	)		(12	)
Net increase (decrease) in cash and cash equivalents	$	85,143		$	(1,778	)

     Historically, our sources of cash have included:

• issuance of equity and debt securities, including cash generated from the exercise of stock options and participation in our ESPP;

• cash generated from operations, primarily from the collection of accounts receivable resulting from product sales; and

• interest income.

     Our historical cash outflows have primarily been associated with:

• cash used for operating activities such as the purchase and growth of inventory, expansion of our sales and marketing and research and development infrastructure and other working capital needs;

• expenditures related to increasing our manufacturing capacity and improving our manufacturing efficiency; and

• cash used for our stock repurchases.

     Other factors that impact our cash inflow and outflow include the following:

• significant increases in our product and services revenue, leading to gross margins greater than 67% in each of the last three years. As our product sales have increased significantly since 2001, our gross profit and operating income have increased significantly as well, providing us with an increased source of cash to finance the expansion of our operations; and

• fluctuations in our working capital.

     As of April 1, 2007, we had cash, cash equivalents and marketable securities of $326.8 million compared to $130.8 million as of December 31, 2006. The primary inflows of cash during the three months ended April 1, 2007 were approximately $390.7 million and $92.4 million generated from the net proceeds of our convertible debt offering and sale of warrants, respectively, in February 2007. In addition, on January 26, 2007, we completed the merger with Solexa, which resulted in net cash acquired of $76.7 million. The primary cash outflows during the three months ended April 1, 2007 were attributable to the repurchase of an aggregate of 7.4 million shares of our common stock for approximately $250.9 million, as well as approximately $139.0 million for the purchase of convertible note hedges. These convertible note transactions and our stock repurchase program are discussed in detail below.

     On February 16, 2007, we issued $400 million principal amount of 0.625% Convertible Senior Notes due 2014 (the Notes). The net proceeds from the offering, after deducting the initial purchasers’ discount and offering expenses, were approximately $390.7 million. We used approximately $201.6 million of the net proceeds to purchase approximately 5.8 million shares of our common stock in privately negotiated transactions concurrently with the offering. We used $46.6 million of the net proceeds of this offering to pay the cost of convertible note hedge and warrant transactions, which are designed to reduce the potential dilution upon conversion of the notes. We intend to use the balance of the net proceeds for other general corporate purposes, which may include

30

acquisitions and additional repurchases of our common stock. The notes mature on February 15, 2014 and bear interest semi-annually at a rate of 0.625% per year, payable on February 15 and August 15 of each year, beginning on August 15, 2007. In addition, we may in certain circumstances be obligated to pay additional interest. If a “designated event,” as defined in the indenture for the notes, occurs, holders of the notes may require us to repurchase all or a portion of their notes for cash at a repurchase price equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest. In addition, upon conversion of the notes, we must pay the principal portion in cash. The notes will become convertible only in certain circumstances based on conditions relating to the trading price of the notes and our common stock or upon the occurrence of specified corporate events. However, the notes will be convertible at any time from, and including, November 15, 2013 through the third scheduled trading day immediately preceding February 15, 2014.

     On February 20, 2007, we executed a Rule 10b5-1 trading plan to repurchase up to $75.0 million of our outstanding common stock over a period of six months. During the three months ended April 1, 2007, we repurchased approximately 1.6 million shares of our common stock under this plan for approximately $49.3 million in cash. In any period, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders’ equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

     Our primary short-term needs for capital, which are subject to change, include expenditures related to:

• the repurchase of our common stock;

• the continued advancement of research and development efforts;

• support of our commercialization efforts related to our current and future products, including expansion of our direct sales force and field support resources both in the United States and abroad;

• improvements in our manufacturing capacity and efficiency;

• our facilities expansion needs, including costs of leasing additional facilities;

• the acquisition of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities; and

• ongoing costs associated with our litigation with Affymetrix, including any potential damages and/or royalties that may be awarded to Affymetrix.

     For 2007, we plan to spend approximately $16.5 million in cash for capital expenditures, primarily for manufacturing and research and development equipment, furniture, fixtures and computer equipment. However, this estimate may change significantly based on the factors described in this section. As of April 1, 2007, we have expended $3.2 million of this amount. We intend to use our currently available cash and cash we expect to generate from operating activities to address our capital requirements. We expect that the performance of our product sales and the resulting operating income, as well as the status of each of our new product development programs, will significantly impact our cash management decisions.

     We anticipate that our current cash and cash equivalents and income from operations will be sufficient to fund our operating needs for at least the next twelve months. Operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. At the present time, we have no material commitments for capital expenditures. However, our future capital requirements and the adequacy of our available funds will depend on many factors, including:

• the successful resolution of our litigation with Affymetrix;

• our ability to successfully commercialize our sequencing and VeraCode technologies and to expand our SNP genotyping services product lines;

31

• scientific progress in our research and development programs and the magnitude of those programs;

• competing technological and market developments; and

• the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings.

     As a result of the factors listed above, we may require additional funding in the future. Our failure to raise capital on acceptable terms, when needed, could have a material adverse effect on our business.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Sensitivity

     Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. The fair market value of fixed rate securities may be adversely impacted by fluctuations in interest rates while income earned on floating rate securities may decline as a result of decreases in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We attempt to ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in investment grade securities. We have historically maintained a relatively short average maturity for our investment portfolio, and we believe a hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of our interest-sensitive financial instruments.

Foreign Currency Exchange Risk

     Although most of our revenue is realized in U.S. dollars, some portions of our revenue are realized in foreign currencies. As a result, our financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets. The functional currencies of our subsidiaries are their respective local currencies. Accordingly, the accounts of these operations are translated from the local currency to the U.S. dollar using the current exchange rate in effect at the balance sheet date for the balance sheet accounts, and using an approximated weighted average exchange rate during the period for revenue and expense accounts. The effects of translation are recorded in accumulated other comprehensive income as a separate component of stockholders’ equity.

     Periodically, we hedge significant foreign currency firm sales commitments and accounts receivable with forward contracts. We only use derivative financial instruments to reduce foreign currency exchange rate risks; we do not hold any derivative financial instruments for trading or speculative purposes. We primarily use forward exchange contracts to hedge foreign currency exposures and they generally have terms of one year or less. These contracts have been designated as cash flow hedges and accordingly, to the extent effective, any unrealized gains or losses on these foreign currency forward contracts are reported in other comprehensive income. Realized gains and losses for the effective portion are recognized with the underlying hedge transaction. As of April 1, 2007, we had no foreign currency forward contracts outstanding. The notional settlement amount of the foreign currency forward contracts outstanding at April 1, 2007 and April 2, 2006 was $0 and $0.1 million, respectively. For the three months ended April 1, 2007 and April 2, 2006, there were no amounts recognized in earnings due to hedge ineffectiveness and we settled foreign exchange contracts of $0 and $0.1 million, respectively.

Item 4. Controls and Procedures.

     We design our internal controls to provide reasonable assurance that (1) our transactions are properly authorized; (2) our assets are safeguarded against unauthorized or improper use; and (3) our transactions are properly recorded and reported in conformity with U.S. generally accepted accounting principles. We also maintain internal controls and procedures to ensure that we comply with applicable laws and our established financial policies.

     We have carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Securities Exchange Act), as of April 1, 2007. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of April 1, 2007, our disclosure controls and procedures are effective to ensure that (a) the information required

32

to be disclosed by us in the reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (b) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management have concluded that the disclosure controls and procedures are effective at the reasonable assurance level. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

     An evaluation was also performed under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of any change in our internal control over financial reporting that occurred during the first quarter of 2007 and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any such change.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

     We have incurred substantial costs in defending ourselves against patent infringement claims and expect to devote substantial financial and managerial resources to protect our intellectual property and to defend against the claims described below as well as any future claims asserted against us.

Affymetrix Litigation

     On July 26, 2004, Affymetrix, Inc. (Affymetrix) filed a complaint in the U.S. District Court for the District of Delaware alleging that the use, manufacture and sale of our BeadArray products and services, including our Array Matrix and BeadChip products, infringe six Affymetrix patents. Affymetrix seeks an injunction against the sale of any products that may ultimately be determined to infringe these patents, unspecified monetary damages, interest and attorneys’ fees. On September 15, 2004, we filed our answer to Affymetrix’ complaint, seeking declaratory judgments from the court that we do not infringe the Affymetrix patents and that such patents are invalid, and we filed counterclaims against Affymetrix for unfair competition and interference with actual and prospective economic advantage.

     On February 15, 2006, the court allowed us to file our first amended answer and counterclaims, adding allegations of inequitable conduct with respect to all six asserted Affymetrix patents, violation of Section 2 of the Sherman Act, and unclean hands. In March 2006, Affymetrix notified us of its decision to drop one of the six patents from the suit, and of its intention to assert infringement of certain additional claims of the remaining five patents. On June 30, 2006, the court dismissed the patent Affymetrix had sought to withdraw from the suit. Both parties filed summary judgment motions by the July 14, 2006 deadline established by the court, and all such motions have now been stayed or denied. On August 16, 2006, the court issued a ruling on the Markman (claim construction) hearing it held on April 20, 2006. At the parties’ request, the trial was rescheduled to March 5, 2007 from October 16, 2006. In a February 2007 pre-trial order, the court established a multi-phase trial structure. The court explained that it decided to address our defenses of invalidity and enforceability of the patents-in-suit, as well as our claims for unfair competition and antitrust violations, in subsequent trials.

     The first phase, which began on March 5, 2007, addressed the issues of infringement and damages. On March 13, 2007, the jury returned a verdict finding infringement of the five patents asserted by Affymetrix. That finding was made without consideration of the validity and enforceability of these five Affymetrix patents. The jury awarded retroactive damages for certain product sales prior to the end of 2005 at a royalty rate of 15% in an amount of approximately $16.7 million. This first-phase verdict remains subject to our post-trial motions and appeals. A judgment on this verdict has not been entered in the case and we do not believe such judgment, along with any final damages award, will be entered until after the subsequent phases of the trial are completed.

     To the extent we succeed in proving some or all of Affymetrix’ patents invalid or unenforceable, the damages amount may be reduced, including to zero, and the court may require a new trial on the damages amount. If we are not successful in the subsequent phases, damages may be assessed, in addition to the $16.7 million amount, on post-2005 sales of our products that were found to infringe the Affymetrix patents. Affymetrix has also asserted that our products launched post-2005 infringe these patents, but these other products were not at issue in the prior jury trial, and the court has yet to indicate how the issues of infringement and potential damages will be judged for these other products. In addition, Affymetrix is contending that our infringement was willful, and if a jury finds our infringement to be willful, the judge will have the discretion to increase any damage award by up to three times. Affymetrix has also contended that it should be awarded its attorney’s fees and pre-judgment interest on any damages award.

     The second phase of the trial, which will include trial as to the validity of the Affymetrix patents being asserted, will be tried before a different jury and is expected to be scheduled later in 2007. Our defense of inequitable conduct, and our counterclaims for tortious interference and unfair competition by Affymetrix, will be addressed in a third phase of the trial. In order for Affymetrix to prevail in the case and receive a judgment in its favor, the patent claims found to have been infringed must also be found to be valid and enforceable in the remaining phases of the trial, and then such findings must be upheld on appeal. We believe we have prior art that pre-dates and invalidates the Affymetrix patents. We are also claiming that the inventors or their agents engaged in inequitable conduct before the United States Patent and Trademark Office in connection with the prosecution of one or more of the patents in-suit, and we believe that this conduct should render the affected patents unenforceable.

     In the second and third phases of the trial, the Affymetrix patents will be presumed to be valid and we will have the burden of proving, by clear and convincing evidence, that the patents are invalid and/or unenforceable. To the extent we are unable to prove

34

invalidity or unenforceability, the court will likely enter a judgment against us and assess damages. Affymetrix is also seeking an injunction to prevent us from making, selling or offering to sell products that infringe patents that are found valid and enforceable.

     Although we believe that we have strong defenses to Affymetrix’ patent claims, the results of litigation are difficult to predict and no assurance can be given that we will succeed in proving the patents were not infringed, or are invalid or unenforceable. As discussed above, the judge overseeing the case has discretion over how and when issues in the case will be tried, and over the granting and scope of any injunction against us. Any damages award or injunction would be subject to appeal and we will carefully consider an appeal at the appropriate time. In such a case, if we choose to appeal, we would likely be required to post a bond or provide other security for some or the entire amount of the final damages award during the appeal, and such amount may be material.

     We have analyzed the potential for a loss from this litigation in accordance with SFAS No. 5, Accounting for Contingencies. Due to our beliefs about our position in the case, and because we are unable to reasonably estimate the amount of loss we would incur if we do not prevail, we have not recorded a reserve for contingent loss. Should we ultimately lose the lawsuit, such result could have a material adverse effect on our consolidated results of operations for the period in which the loss is recorded.

Dr. Anthony W. Czarnik v. Illumina, Inc.

     On June 15, 2005, Dr. Anthony Czarnik, a former employee, filed suit against us in the U.S. District Court for the District of Delaware seeking correction of inventorship of certain of our patents and patent applications and alleging that we committed inequitable conduct and fraud in not naming him as an inventor. Dr. Czarnik seeks an order requiring us and the U.S. Patent and Trademark Office to correct the inventorship of certain of our patents and patent applications by adding Dr. Czarnik as an inventor, a judgment declaring certain of our patents and patent applications unenforceable, unspecified monetary damages and attorney’s fees. On August 4, 2005, we filed a motion to dismiss the complaint for lack of standing and failure to state a claim. While this motion was pending, Dr. Czarnik filed an amended complaint on September 23, 2005. On October 7, 2005, we filed a motion to dismiss the amended complaint for lack of standing and failure to state a claim. On July 13, 2006, the court granted our motion to dismiss the counts of Dr. Czarnik’s complaint dealing with correction of inventorship in pending applications and inequitable conduct. On July 27, 2006, we filed an answer to the two remaining counts of the amended complaint (correction of inventorship in issued patents, and fraud). On March 28, 2007, the court issued a Scheduling Order in which it contemplates holding a claim construction hearing in January 2008 if it deems claim construction to be necessary. A trial date has yet to be set for this case. We believe we have meritorious defenses against these claims.

ITEM 1A. Risk Factors.

     Our business is subject to various risks, including those described below. In addition to the other information included in this Form 10-Q, the following issues could adversely affect our operating results or our stock price.

Litigation or other proceedings or third party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products or services or impact our stock price.

     Our commercial success depends in part on our non-infringement of the patents or proprietary rights of third parties and on our ability to protect our own intellectual property. As we have previously disclosed, Affymetrix, Inc. filed a complaint against us in July 2004 in federal court in Wilmington, Delaware, alleging infringement of six of its patents.

     On June 30, 2006, the court dismissed a patent Affymetrix had sought to withdraw from its suit leaving five patents being asserted against us. On August 16, 2006, the court issued a ruling on the claim construction hearing that it had held on April 20, 2006 as part of this litigation. At the request of both parties, the trial was rescheduled to March 5, 2007 from October 16, 2006. In a February 2007 pre-trial order, the court explained that it had decided to address our defenses of invalidity and enforceability of the patents-in-suit, as well as our claims for unfair competition and antitrust violations, in subsequent trials. The March 5, 2007 trial led to a jury finding of infringement of the five patents asserted by Affymetrix. That finding was made without consideration of the validity and enforceability of these five Affymetrix patents. The jury also ordered us to pay damages based on a royalty of 15% for certain products that we launched and sold before the end of 2005. The total amount of damages awarded by the jury was $16.7 million. Although we believe the subsequent trials will confirm the invalidity and unenforceability positions we have taken with respect to the patents asserted by Affymetrix, we cannot assure you that the court will find these patents to be invalid or unenforceable. In addition, patents enjoy a presumption of validity that can be rebutted only by clear and convincing evidence. Any

35

adverse ruling or perception of an adverse ruling throughout these proceedings will likely have a material adverse impact on our stock price, which may be disproportionate to the actual import of the ruling itself.

     Third parties, including Affymetrix, have asserted or may assert that we are employing their proprietary technology without authorization. As we enter new markets, we expect that competitors will likely assert that our products infringe their intellectual property rights as part of a business strategy to impede our successful entry into those markets. In addition, third parties may have obtained and may in the future obtain patents allowing them to claim that the use of our technologies infringes these patents. We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against any of these claims. Furthermore, parties making claims against us may be able to obtain injunctive or other relief, which effectively could block our ability to develop further, commercialize and sell products, and could result in the award of substantial damages against us. In the event of a successful claim of infringement against us, we may be required to pay damages and obtain one or more licenses from third parties, or be prohibited from selling certain products. We may not be able to obtain these licenses at a reasonable cost, if at all. We could therefore incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins. In addition, we could encounter delays in product introductions while we attempt to develop alternative methods or products. Defense of any lawsuit or failure to obtain any of these licenses on favorable terms could prevent us from commercializing products, and the prohibition of sale of any of our products could materially affect our ability to grow and maintain profitability.

We expect intense competition in our target markets, which could render our products obsolete, result in significant price reductions or substantially limit the volume of products that we sell. This would limit our ability to compete and maintain profitability. If we cannot continuously develop and commercialize new products, our revenue may not grow as intended.

     We compete with life sciences companies that design, manufacture and market instruments for analysis of genetic variation and biological function and other applications using technologies such as two-dimensional electrophoresis, capillary electrophoresis, mass spectrometry, flow cytometry, microfluidics, nanotechnology, next-generation DNA sequencing and mechanically deposited, inkjet and photolithographic arrays. We anticipate that we will face increased competition in the future as existing companies develop new or improved products and as new companies enter the market with new technologies. The markets for our products are characterized by rapidly changing technology, evolving industry standards, changes in customer needs, emerging competition, new product introductions and strong price competition. For example, prices per data point for genotyping have fallen significantly over the last two years and we anticipate that prices will continue to fall. One or more of our competitors may render our technology obsolete or uneconomical. Some of our competitors have greater financial and personnel resources, broader product lines, a more established customer base and more experience in research and development than we do. Furthermore, life sciences and pharmaceutical companies, which are our potential customers and strategic partners, could develop competing products. If we are unable to develop enhancements to our technology and rapidly deploy new product offerings, our business, financial condition and results of operations will suffer.

We may encounter difficulties in integrating acquisitions that could adversely affect our business.

     We acquired Solexa, Inc. (Solexa) in January 2007 and CyVera Corporation in April 2005 and we may in the future acquire technology, products or businesses related to our current or future business. We have limited experience in acquisition activities and may have to devote substantial time and resources in order to complete acquisitions. Further, these potential acquisitions entail risks, uncertainties and potential disruptions to our business. For example, we may not be able to successfully integrate a company’s operations, technologies, products and services, information systems and personnel into our business. An acquisition may further strain our existing financial and managerial resources, and divert management’s attention away from our other business concerns. In connection with these acquisitions, we assumed certain liabilities and hired certain employees, which is expected to continue to result in an increase in our research and development expenses and capital expenditures. There may also be unanticipated costs and liabilities associated with an acquisition that could adversely affect our operating results. To finance any acquisitions, we may choose to issue shares of our common stock as consideration, which would result in dilution to our stockholders. Additionally, an acquisition may have a substantial negative impact on near-term expected financial results.

     The success of the Solexa merger will depend, in part, on our ability to realize the anticipated synergies, growth opportunities and cost savings from integrating Solexa’s businesses with our businesses. Our success in realizing these benefits and the timing of this realization depend upon the successful integration of the operations of Solexa. The integration of two independent companies is a complex, costly and time-consuming process. The difficulties of combining the operations of the companies include, among other factors:

36

• lost sales and customers as a result of certain customers of either of the two companies deciding not to do business with the combined company;

• complexities associated with managing the combined businesses;

• integrating personnel from diverse corporate cultures while maintaining focus on providing consistent, high quality products and customer service;

• coordinating geographically separated organizations, systems and facilities;

• potential unknown liabilities and unforeseen increased expenses or delays associated with the merger; and

• performance shortfalls at one or both of the companies as a result of the diversion of management’s attention to the merger.

     If we are unable to successfully combine the businesses in a manner that permits the combined company to achieve the cost savings and operating synergies anticipated to result from the merger, such anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected. In addition, we and Solexa have operated and will continue to operate independently. It is possible that the integration process could result in the loss of key employees, diversion of each company’s management’s attention, the disruption or interruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with customers and employees or our ability to achieve the anticipated benefits of the merger, or could reduce our earnings or otherwise adversely affect the business and financial results of the combined company.

The combined company may fail to realize the anticipated benefits of the merger as a result of our failure to achieve anticipated revenue growth following the merger.

     For various reasons, including significant competition, low market acceptance or market growth, and lack of technology advantage, the Solexa acquisition may not grow as anticipated and if so, we may not realize the expected value from this transaction.

The merger will cause dilution of our earnings per share.

     The merger and the transactions contemplated by the merger agreement are expected to have a dilutive effect on our earnings per share at least through 2007 due to losses of Solexa, the additional shares of our common stock that were issued in the merger, the transaction and integration-related costs and other factors such as the potential failure to realize any benefit from synergies anticipated in the merger. These factors could adversely affect the market price of our common stock.

Solexa had a material weakness in its internal controls over financial reporting as of December 31, 2005. If additional material weaknesses are identified in the future, current and potential stockholders could lose confidence in our consolidated financial reporting, which could harm our business and the trading of our common stock.

     As of December 31, 2005, Solexa did not maintain effective control over the application of GAAP related to the financial reporting process. This control deficiency resulted in numerous adjustments being required to bring Solexa’s financial statements into compliance with GAAP. Additionally, this deficiency could have resulted in material misstatement of the annual or interim consolidated financial statements that would not be prevented or detected. Accordingly, Solexa’s management determined that this control deficiency constituted a material weakness. Because of this material weakness, Solexa’s management concluded that, as of December 31, 2005, it did not maintain effective internal control over financial reporting based on those criteria. Should we, or our independent registered public accounting firm, determine in future fiscal periods that there are material weaknesses in our consolidated internal controls over financial reporting (including Solexa), the reliability of our financial reports may be impacted, and our results of operations or financial condition may be harmed and the price of our common stock may decline.

37

Any inability to adequately protect our proprietary technologies could harm our competitive position.

     Our success will depend in part on our ability to obtain patents and maintain adequate protection of our intellectual property in the United States and other countries. If we do not protect our intellectual property adequately, competitors may be able to use our technologies and thereby erode our competitive advantage. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant challenges in protecting their proprietary rights abroad. These challenges can be caused by the absence of rules and methods for the establishment and enforcement of intellectual property rights abroad.

     The patent positions of companies developing tools for the life sciences and pharmaceutical industries, including our patent position, generally are uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. We intend to apply for patents covering our technologies and products, as we deem appropriate. However, our patent applications may be challenged and may not result in issued patents or may be invalidated or narrowed in scope after they are issued. Questions as to inventorship may also arise. For example, in June 2005, a former employee filed a complaint against us, claiming he is entitled to be named as joint inventor of certain of our U.S. patents and pending U.S. and foreign patent applications, and seeking a judgment that the related patents and applications are unenforceable. Any finding that our patents and applications are unenforceable could harm our ability to prevent others from practicing the related technology, and a finding that others have inventorship rights to our patents and applications could require us to obtain certain rights to practice related technologies, which may not be available on favorable terms, if at all.

     In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products. There also is risk that others may independently develop similar or alternative technologies or design around our patented technologies. Also, our patents may fail to provide us with any competitive advantage. We may need to initiate additional lawsuits to protect or enforce our patents, or litigate against third party claims, which would be expensive and, if we lose, may cause us to lose some of our intellectual property rights and reduce our ability to compete in the marketplace. Furthermore, these lawsuits may divert the attention of our management and technical personnel.

     We also rely upon trade secret protection for our confidential and proprietary information. We have taken security measures to protect our confidential information. These measures, however, may not provide adequate protection for our trade secrets or other confidential information. Among other things, we seek to protect our trade secrets and confidential information by entering into confidentiality agreements with employees, collaborators and consultants. Nevertheless, employees, collaborators or consultants may still disclose our confidential information, and we may not otherwise be able to effectively protect our trade secrets. Accordingly, others may gain access to our confidential information, or may independently develop substantially equivalent information or techniques.

If we are unable to develop and maintain operation of our manufacturing capability, we may not be able to launch or support our products in a timely manner, or at all.

     We currently possess limited facilities capable of manufacturing our principal products and services for both sale to our customers and internal use. If a natural disaster were to significantly damage our facility or if other events were to cause our operations to fail, these events could prevent us from developing and manufacturing our products and services. Also, many of our manufacturing processes are automated and are controlled by our custom-designed Laboratory Information Management System (LIMS). Additionally, as part of the decoding step in our array manufacturing process, we record several images of each array to identify what bead is in each location on the array and to validate each bead in the array. This requires significant network and storage infrastructure. If either our LIMS system or our networks or storage infrastructure were to fail for an extended period of time, it would adversely impact our ability to manufacture our products on a timely basis and may prevent us from achieving our expected shipments in any given period.

Our manufacturing capacity may limit our ability to sell our products.

     We continue to ramp up our capacity to meet the anticipated demand for our products. Although we have significantly increased our manufacturing capacity and we believe that we have sufficient plans in place to ensure we have adequate capacity to meet our business plan in 2007 and 2008, there are uncertainties inherent in expanding our manufacturing capabilities and we may not be able to increase our capacity in a timely manner. For example, manufacturing and product quality issues may arise as we increase

38

production rates at our manufacturing facility and launch new products. As a result, we may experience difficulties in meeting customer, collaborator and internal demand, in which case we could lose customers or be required to delay new product introductions, and demand for our products could decline. Additionally, in the past, we have experienced variations in manufacturing conditions that have temporarily reduced production yields. Due to the intricate nature of manufacturing products that contain DNA, we may encounter similar or previously unknown manufacturing difficulties in the future that could significantly reduce production yields, impact our ability to launch or sell these products, or to produce them economically, prevent us from achieving expected performance levels or cause us to set prices that hinder wide adoption by customers.

If we are unable to find third-party manufacturers to manufacture components of our products, we may not be able to launch or support our products in a timely manner, or at all.

     The nature of our products requires customized components that currently are available from a limited number of sources. For example, we currently obtain the fiber optic bundles and BeadChip slides included in our products from single vendors. If we are unable to secure a sufficient supply of those or other product components, we will be unable to meet demand for our products. We may need to enter into contractual relationships with manufacturers for commercial-scale production of some of our products, or develop these capabilities internally, and we cannot assure you that we will be able to do this on a timely basis, for sufficient quantities or on commercially reasonable terms. Accordingly, we may not be able to establish or maintain reliable, high-volume manufacturing at commercially reasonable costs.

We have a significant amount of indebtedness. We may not be able to make payments on our indebtedness, and we may incur additional indebtedness in the future, which could adversely affect our operation and profitability.

     In February 2007, we issued $400 million of 0.625% convertible senior notes due February 2014. The notes bear interest semi-annually, mature on February 15, 2014 and obligate us to repurchase the notes at the option of the holders if a “designated event” (as defined in the indenture for the notes), such as certain merger transactions involving us, occurs. In addition, upon conversion of the notes, we must pay in cash the principal portion of the notes being converted. Our ability to make payments on the notes will depend on our future operating performance and our ability to generate cash and may also depend on our ability to obtain additional debt or equity financing. We may need to use our cash to pay principal and interest on our debt, which will reduce the funds available to fund our research and development programs, strategic initiatives and working capital requirements. Our ability to generate sufficient operating cash flow to service the notes and fund our operating requirements will depend on our continued ability to commercialize new products and expand our manufacturing capabilities. Our debt service obligations increase our vulnerabilities to competitive pressures, because our competitors may be less leveraged than us. If we are unable to generate sufficient operating cash flow to service our indebtedness and fund our operating requirements, we may be forced to reduce our development programs or seek additional debt or equity financing, which may not be available to us on satisfactory terms, or at all, or may dilute the interests of our existing stockholders. Our level of indebtedness may make us more vulnerable to economic or industry downturns. If we incur new indebtedness, the risks relating to our business and our ability to service our indebtedness will intensify.

We expect that our results of operations will fluctuate. This fluctuation could cause our stock price to decline.

     Our revenue is subject to fluctuations due to the timing of sales of high-value products and services projects, the impact of seasonal spending patterns, the timing and size of research projects our customers perform, changes in overall spending levels in the life sciences industry, and other unpredictable factors that may affect customer ordering patterns. Given the difficulty in predicting the timing and magnitude of sales for our products and services, we may experience quarter-to-quarter fluctuations in revenue resulting in the potential for a sequential decline in quarterly revenue. A large portion of our expenses are relatively fixed, including expenses for facilities, equipment and personnel. In addition, we expect operating expenses to continue to increase significantly. Accordingly, if revenue does not grow as anticipated, we may not be able to maintain annual profitability. Any significant delays in the commercial launch of our products, unfavorable sales trends in our existing product lines, or impacts from the other factors mentioned above, could adversely affect our future revenue growth or cause a sequential decline in quarterly revenue. Due to the possibility of fluctuations in our revenue and expenses, we believe that quarterly comparisons of our operating results are not a good indication of our future performance. If our operating results fluctuate or do not meet the expectations of stock market analysts and investors, our stock price could decline.

39

Our sales, marketing and technical support organization may limit our ability to sell our products.

     We currently have fewer resources available for sales and marketing and technical support services compared to some of our primary competitors. In order to effectively commercialize our sequencing, genotyping and gene expression systems and other products to follow, we will need to expand our sales, marketing and technical support staff both domestically and internationally. We may not be successful in establishing or maintaining either a direct sales force or distribution arrangements to market our products and services. In addition, we compete primarily with much larger companies that have larger sales and distribution staffs and a significant installed base of products in place, and the efforts from a limited sales and marketing force may not be sufficient to build the market acceptance of our products required to support continued growth of our business.

We have only recently achieved annual operating profitability.

     Prior to 2006, we had incurred net losses each year since our inception. As of April 1, 2007, our accumulated deficit was $402.7 million. Our ability to sustain annual profitability will depend, in part, on the rate of growth, if any, of our revenue and on the level of our expenses. Non-cash stock based compensation expense and expenses related to our acquisition of Solexa in January 2007 are also likely to adversely affect our future profitability. We expect to continue incurring significant expenses related to research and development, sales and marketing efforts to commercialize our products and the continued development of our manufacturing capabilities. In addition, we expect that our research and development and selling and marketing expenses will increase at a higher rate in the future as a result of the development and launch of new products. Even if we maintain profitability, we may not be able to increase profitability on a quarterly basis.

We may encounter difficulties in managing our growth. These difficulties could impair our profitability.

     We have experienced and expect to continue to experience rapid and substantial growth in order to achieve our operating plans, which will place a strain on our human and capital resources. If we are unable to manage this growth effectively, our profitability could suffer. Our ability to manage our operations and growth effectively requires us to continue to expend funds to enhance our operational, financial and management controls, reporting systems and procedures and to attract and retain sufficient numbers of talented employees. If we are unable to scale up and implement improvements to our manufacturing process and control systems in an efficient or timely manner, or if we encounter deficiencies in existing systems and controls, then we will not be able to make available the products required to successfully commercialize our technology. Failure to attract and retain sufficient numbers of talented employees will further strain our human resources and could impede our growth.

Changes in our effective income tax rate could impact our profitability.

     We are subject to income taxes in both the United States and numerous foreign jurisdictions. Significant judgments based on interpretations of existing tax laws or regulations are required in determining our provision for income taxes. Our effective income tax rate could be adversely affected by various factors, including, but not limited to, changes in the mix of earnings in tax jurisdictions with different statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in existing tax laws or tax rates, changes in the level of non-deductible expenses, including share-based compensation, changes in our future levels of research and development spending, mergers and acquisitions, and the result of examinations by various tax authorities.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals.

     We are highly dependent on our management and scientific personnel, including Jay Flatley, our president and chief executive officer, John Stuelpnagel, our senior vice president, general manager of microarrays and chief operating officer and John West, our senior vice president and general manager of sequencing. The loss of their services could adversely impact our ability to achieve our business objectives. We will need to hire additional qualified personnel with expertise in molecular biology, chemistry, biological information processing, sales, marketing and technical support. We compete for qualified management and scientific personnel with other life science companies, universities and research institutions, particularly those focusing on genomics. Competition for these individuals, particularly in the San Diego and San Francisco area, is intense, and the turnover rate can be high. Failure to attract and retain management and scientific personnel would prevent us from pursuing collaborations or developing our products or technologies.

     Our planned activities will require additional expertise in specific industries and areas applicable to the products developed through our technologies, including the life sciences and healthcare industries. Thus, we will need to add new personnel, including management, and develop the expertise of existing management. The failure to do so could impair the growth of our business.

40

A significant portion of our sales are to international customers.

     Approximately 41% and 47% of our revenue for the three months ended April 1, 2007 and April 2, 2006, respectively, was derived from shipments to customers outside the United States. We intend to continue to expand our international presence and export sales to international customers and we expect the total amount of non-U.S. sales to continue to grow. Export sales entail a variety of risks, including:

• currency exchange fluctuations;

• unexpected changes in legislative or regulatory requirements of foreign countries into which we import our products;

• difficulties in obtaining export licenses or in overcoming other trade barriers and restrictions resulting in delivery delays; and

• significant taxes or other burdens of complying with a variety of foreign laws.

     In addition, sales to international customers typically result in longer payment cycles and greater difficulty in accounts receivable collection. We are also subject to general geopolitical risks, such as political, social and economic instability and changes in diplomatic and trade relations. One or more of these factors could have a material adverse effect on our business, financial condition and operating results.

Our success depends upon the continued emergence and growth of markets for analysis of genetic variation and biological function.

     We design our products primarily for applications in the life sciences and pharmaceutical industries. The usefulness of our technology depends in part upon the availability of genetic data and its usefulness in identifying or treating disease. We are focusing on markets for analysis of genetic variation and biological function, namely sequencing, SNP genotyping and gene expression profiling. These markets are new and emerging, and they may not develop as quickly as we anticipate, or reach their full potential. Other methods of analysis of genetic variation and biological function may emerge and displace the methods we are developing. Also, researchers may not seek or be able to convert raw genetic data into medically valuable information through the analysis of genetic variation and biological function. In addition, factors affecting research and development spending generally, such as changes in the regulatory environment affecting life sciences and pharmaceutical companies, and changes in government programs that provide funding to companies and research institutions, could harm our business. If useful genetic data is not available or if our target markets do not develop in a timely manner, demand for our products may grow at a slower rate than we expect, and we may not be able to sustain annual profitability.

3 GRANT

     3.1 Subject to Public Law 96-517 and Public Law 98-620, TUFTS hereby grants, to the extent that it lawfully may, to LICENSEE and LICENSEE hereby accepts an exclusive license under the Exclusive Technology to make, have made, import, have imported, use, lease, sell and offer for sale, have sold and otherwise commercialize and exploit Licensed Products, and to practice any method, process, or procedure within the Exclusive Technology, in the Licensed Territory.

-2-

     3.2 Said license is Exclusive, including the right to sublicense pursuant to Section 12, in the Licensed Territory for a term commencing as of the Effective Date, and ending upon expiration of the last to expire of Licensed Patents.

     3.3 LICENSEE agrees that TUFTS shall have the right to practice the Exclusive Technology both on its own and/or in collaboration with third party academic or not-for-profit research institutions, solely for non-commercial purposes, and not for sale, license, or other distribution.

4 DILIGENCE

     4.1 LICENSEE will use reasonable best efforts to diligently and continuously commercialize the Exclusive Technology. To support the commercialization of the Exclusive Technology, LICENSEE will raise $500,000 in equity financing from third parties during the first year after the Effective Date and use its best efforts to raise $2,000,000 in total financing (including but not limited to equity or debt financing, government grant funding, sponsored research and development funding, etc.) (“First Financing”) during the second year after the Effective Date. If LICENSEE fails to meet any one of the foregoing milestones within the time specified, TUFTS shall have the right to terminate the license granted hereunder, provided that such action by TUFTS is consistent with a determination of the arbitrators pursuant to Section 15 hereof that LICENSEE has failed to exercise due diligence in the commercialization of the Exclusive Technology pursuant to its obligations under this Section 4.1.

     4.2 LICENSEE shall further use its best efforts to bring one or more Licensed Products to market through a thorough, vigorous and diligent exploitation of Licensed Patents and to continue thereafter active, diligent marketing of more Licensed Products throughout the life of this Agreement.

     4.3 In addition LICENSEE shall adhere to the following milestones:

(a)	LICENSEE shall deliver to TUFTS on or before the first anniversary of this Agreement an operating plan showing the amount of money, number and kind of personnel, and time budgeted and planned for each phase of development of the Licensed Products and shall provide similar reports to TUFTS on or before each subsequent anniversary. TUFTS agrees to keep this operating plan confidential.
(b)	The following expenditures shall be made by the LICENSEE, its Affiliates or its sublicensees on a calendar-year basis in order to develop and commercialize Licensed Products:

1999 – an expenditure of $1,000,000

2002 – an expenditure of $2,500,000

-3-

(c) Of the expenditures listed in Section 4.3(b), the following minimum expenditures shall be made by LICENSEE, its Affiliates or its sublicensees on a calendar-year basis in order to develop and commercialize a product dominated by US Patent Number 5,512,490:

1999 – an expenditure of $250,000
2000 – an expenditure of $375,000
2001 – an expenditure of $500,000

(e)	LICENSEE shall provide TUFTS with an annual report of research and development expenditures required under this Section 4.3.

     4.4 If LICENSEE fails to meet any of the milestones in this Section 4, and the default has not been remedied within ninety (90) days after the date of notice in writing of such default by TUFTS, TUFTS shall have the right to change the license granted hereunder to a non-exclusive license.

5 PAYMENTS

     5.1 LICENSEE shall pay to TUFTS royalties equal to three percent (3.0%) of the Net Sales received by LICENSEE from the sale of Licensed Products. In the event that a Licensed Product under this Agreement is sold in a combination product containing one or more other active ingredients or components which are or could be separately available on a commercial basis, then Net Sales on the combination product shall be calculated as follows:

By multiplying the net selling price of the combination product by the fraction A/A+B, where A is the gross selling price, during the royalty-paying period being considered, of the Licensed Product sold separately, and B is the gross selling price, during the royalty period in question, of the other active ingredients or components sold separately.

     5.2 In the event that LICENSEE is required to take a license from any third party in order to commercialize any Licensed Product, and LICENSEE must make royalty payments to such third party (“Third Party Royalty Payment”), the royalties payable to TUFTS pursuant to Section 5.1 above shall be reduced by an amount equal to fifty percent (50%) of the Third Party Royalty Payment, provided, however, that such reduction shall not reduce the royalty payment owed to Tufts

-4-

in any single year to an amount which is less than fifty per cent (50%) of that which would have been due to TUFTS in the absence of Third Party Royalty Payments.

     5.3 LICENSEE shall pay TUFTS a sublicensing fee (the “Sublicensing Fee”) equal to twenty five percent (25%) of the net revenue received from sublicensing of Licensed Patents and Licensed Products covered by one or more valid claims of the Licensed Patents in the country in which such Product is sold. The Sublicensing Fee shall be based upon the amount actually paid to LICENSEE by a sublicensee, including fees, royalties and milestone payments, provided that the Sublicensing Fee shall not include research and development support payments, payments in compensation for the grant of rights to any other intellectual property of LICENSEE, or equity or debt financing received by LICENSEE from such sublicensee.

     5.4 LICENSEE hereby grants to TUFTS the right to purchase 500,000 shares of LICENSEE’S common stock which represents 10.0% of the founding capitalization (see Exhibit 2), at fair market value as determined by LICENSEE’s Board of Directors as of the date of purchase (such fair market value is currently $0.01 per share) pursuant to a separate stock purchase agreement (“Stock Agreement”).

     5.5 The royalty on Net Sales made in currencies other than U.S. Dollars shall be calculated using the appropriate foreign exchange rate for such currency quoted by the Bank of America (San Francisco) foreign exchange desk, on the close of business on the last banking day of each calendar quarter. Royalties and payments to TUFTS shall be made in U.S. Dollars.

     5.6 Within thirty (30) days after receipt of a statement from TUFTS, LICENSEE shall reimburse TUFTS for all costs incurred by TUFTS after the Effective Date in connection with the preparation, filing and prosecution of all patent applications and maintenance of Licensed Patents.

     5.7 In the event that in any country all of the valid claims within the Licensed Patents which cover a particular Licensed Product are held invalid or unenforceable, then LICENSEE’s obligation to pay royalties on Net Sales with respect to such Licensed Product shall terminate in such country. LICENSEE’s obligation to pay royalties on Net Sales shall terminate on a country-by-country basis upon the expiration of the last to expire of any issued Licensed Patent in each country.

6 ROYALTY REPORTS, PAYMENTS AND ACCOUNTING

     6.1 Beginning with the first sale of a Licensed Product, LICENSEE shall make written reports (even if there are no further sales) of royalty payments due, if any, to TUFTS within thirty (30) days after the end of each calendar quarter. This report shall state the number, description, and aggregate Net Sales of Licensed Products during such completed calendar quarter by LICENSEE, its Affiliates and Sublicensees, and resulting calculations of earned royalty payments due TUFTS pursuant to Section 5 for such completed calendar quarter. Each such statement shall be certified by an officer of the LICENSEE as being true, correct and complete. Concurrent with the submission of

-5-

each such report, LICENSEE shall pay TUFTS any royalties due for the calendar quarter covered by such report.

     6.2 LICENSEE agrees to keep and maintain records for a period of three (3) years showing the manufacture, sale, use and other disposition of products sold or otherwise disposed of under the license herein granted. Such records will include sufficient detail to enable the royalties payable hereunder by LICENSEE to be determined. LICENSEE further agrees to permit its books and records to be examined by an independent certified public accountant selected by TUFTS and acceptable to LICENSEE once per calendar year during the term of this Agreement, for the sole purpose of verifying the reports and royalty payments made by LICENSEE. Such examination shall be made at LICENSEE’S place of business during ordinary business hours with at least thirty (30) days prior written notice. The accountant shall report to TUFTS only whether there has been a royalty underpayment and, if so, the amount thereof. Such examination is to be at the expense of TUFTS except in the event that the results of the audit reveal an under reporting of royalties due TUFTS of five percent (5%) or more, then the audit costs shall be paid by LICENSEE within thirty (30) days of notice by TUFTS to LICENSEE.

     8.1 Indemnity. LICENSEE agrees to indemnify and hold harmless TUFTS, its trustees, officers and employees, from all costs, expenses (including reasonable attorneys’ fees), interest, losses, obligations, liabilities, and damages paid or liability for which is incurred by any of said parties (“Losses”), and which arise out of or are in connection with or are for the purpose of avoiding any and all claims, demands, actions, causes of action, suits, appeals, and proceedings (“Claims”), all whether groundless or not, or the settlement thereof, based on any actual or alleged injuries, damages, or liability of any kind whatsoever (including, without limitation, personal injury, death, property damage, breach of warranty, or breach of contract) arising, directly or indirectly, out of any one or more of: any breach of LICENSEE of its representations, warranties, or agreements hereunder; or out of any manufacture, marketing, possession, use, sale or other disposition of Licensed Products or products furnished by TUFTS to LICENSEE in connection herewith or in connection with the Research Agreement (whether same occurs during or after the License or during or after the License Period) by LICENSEE, its Affiliates, its sublicensees, or anyone claiming by, through, or under any of them; or any acquisition, possession, disclosure, or use of the Exclusive Technology or any thereof, by LICENSEE, its Affiliates, its sublicensees, or anyone claiming by, through, or under any of them; or the presence of LICENSEE’s or its Affiliates’ or its sublicensees’ officers, agents, employees, invitees, or property or any thereof on TUFTS’ premises, provided that the obligations of LICENSEE under this Section 8.1 shall not apply if the Claims and any Losses resulted in whole or in part from the intentional misconduct or gross negligence of TUFTS or any other party indemnified under this Section.

     8.2 Defense; Settlement. LICENSEE shall defend and control negotiation of settlement of any Claim, as defined in Section 8.1. TUFTS agrees to cooperate fully in the defense of any Claim and may participate in the defense with counsel of TUFTS’ choosing, such separate counsel to be at TUFTS’ expense unless a conflict of interest exists between LICENSEE and TUFTS with respect to the defense in which case LICENSEE shall pay the reasonable fees and expenses of TUFTS’ separate counsel. Any settlement by which TUFTS would incur any obligation or liability, whether for the payment of money, the taking of any action, the refraining from any action, or otherwise, shall require the advance written consent of TUFTS, which may be withheld in the sole discretion of TUFTS without relieving LICENSEE of any of its indemnification or other obligations hereunder.

     8.3 Insurance. Not later than thirty (30) days before the time when LICENSEE, any subsidiary, or any sublicensee of LICENSEE shall use in humans or sell any Licensed Products or any products furnished to LICENSEE by TUFTS at any time (before, on or after the date hereof) in connection herewith or in connection with the Research Agreement, and at all times thereafter until the expiration of all applicable statutes of limitation pertaining to any such use, sale or other disposition of any Licensed Products or the aforesaid products furnished by TUFTS (whether same

-8-

Such insurance policy or policies shall be issued by companies rated by A. M. Best as A VIII or better (or other companies acceptable to TUFTS), shall name TUFTS as an additional named insured, shall have limits of at least one million dollars ($1,000,000) per occurrence with an aggregate of three million dollars ($3,000,000), shall be non-cancelable except upon thirty (30) days prior written notice to TUFTS, and shall provide that as to any loss covered thereby and also by any policies obtained by TUFTS itself, LICENSEE’s policies shall provide primary coverage for TUFTS and TUFTS’ policies shall be considered excess coverage for TUFTS.

9 MARKING

     Prior to the issuance of patents under Licensed Patents, LICENSEE agrees to mark Licensed Product(s) (or their containers or labels) made, sold, or otherwise disposed of by it under the license granted in this Agreement with the words “Patent Pending,” and following the issuance of one or more patents, with the numbers of any applicable Licensed Patents.

10 USE OF NAMES

     10.1 Use of Names. LICENSEE, its Affiliates and sublicensees agrees not to use the name of TUFTS or any TUFTS participant in the Research, as defined in the Research Agreement, in any form of publicity or disclosure without TUFTS’ prior written consent, which may be withheld or withdrawn in TUFTS’ discretion at any time, provided however, that no such consent will be required with regard to: (i) any proper reference by LICENSEE to published technical publications by such participants; (ii) disclosures to potential investors and corporate collaborators; and (iii) TUFTS will make no objection to LICENSEE’s such other disclosures as are required as a matter of law (including disclosures made under applicable securities regulation) and such general disclosures of this Agreement as may be desired by LICENSEE for purposes of grant solicitations from governmental authorities.

11 PATENT PROSECUTION AND INFRINGEMENT

     11.1 TUFTS shall have the primary responsibility for the prosecution, filing and maintenance of all Licensed Patents, including the conduct of all interference, opposition, nullity and revocation proceedings, using counsel of its choice; provided, however, that LICENSEE shall have

-9-

reasonable opportunity to advise and consult with TUFTS on such matters and may recommend TUFTS to take such action as LICENSEE reasonably believes necessary to protect the Licensed Patents. Counsel shall concurrently provide TUFTS and LICENSEE with copies of all material correspondence related to the prosecution of the patent applications within the Licensed Patents. Should TUFTS elect to abandon any patent or patent application in any country, it shall give timely notice to LICENSEE, who may continue prosecution or maintenance, at its sole expense and TUFTS shall have no further rights with respect to such patent application or patent in such country. In the event that a conflict arises with respect to patent counsel selected by TUFTS, LICENSEE may, with just cause and after consulting with TUFTS, select new patent counsel reasonably acceptable to TUFTS.

     11.2 Payment of all reasonable fees and costs relating to the filing, prosecution and maintenance of Licensed Patents which are incurred by TUFTS after the Effective Date (including interference and/or opposition, nullity and revocation proceedings) shall be the responsibility of LICENSEE. TUFTS shall periodically send LICENSEE invoices for any such patent expenses incurred by TUFTS and LICENSEE shall pay such invoices within thirty (30) days of receipt thereof.

     11.3 Each party shall inform the other promptly in writing of any alleged infringement of the Licensed Patents by a third party, including all detail then available. TUFTS shall have the right, but shall not be obligated, to prosecute at its own expense any such infringements, and LICENSEE agrees that TUFTS may join LICENSEE as a plaintiff at the expense of TUFTS. In any infringement action commenced or defended solely by TUFTS, all expenses and all recovery for infringement shall be those of TUFTS.

     11.4 If TUFTS has not taken legal action or been successful in obtaining cessation of the infringement, within one hundred eighty (180) days of written notification from LICENSEE of such infringement, or if TUFTS elects not to continue prosecuting any legal action against an infringer, LICENSEE shall have the right (while the LICENSEE is the exclusive licensee), but shall not be obligated, to prosecute at its own expense any such infringement. LICENSEE may join TUFTS as a plaintiff in any such infringement suit at LICENSEE’s expense. No settlement, consent judgment or other voluntary final disposition of the suit may be entered into without TUFTS’ consent, which shall not be unreasonably withheld or delayed. In any such action by LICENSEE, after LICENSEE is first reimbursed for LICENSEE’s costs and expenses (including attorney’s and expert fees) and then TUFTS is reimbursed for any credited royalties pursuant to Section 11.8, TUFTS shall be entitled to receive an amount equal to the applicable royalties on any recovery of profits and damages that is in excess of LICENSEE’s costs and expenses and TUFTS’ royalty reimbursement. LICENSEE shall indemnify TUFTS against any order for costs or other payments that may be made against TUFTS in such proceedings.

     11.5 If any declaratory judgment action alleging invalidity or non-infringement of any of the Licensed Patents shall be brought against LICENSEE, TUFTS shall have the right at its election

-10-

made within sixty (60) days after commencement of that action, to intervene and take over the sole defense of the action at its expense.

     11.6 In any infringement suit that either party brings to enforce the Licensed Patents, the other party shall at the request and expense of the party bringing the suit, cooperate in al reasonable respects, including, to the extent possible, obtaining the testimony of its employees and making available physical evidence in the possession of that party.

     11.7 LICENSEE, during the exclusive period of this Agreement, shall have the exclusive right in accordance with the provisions of Section 12, to sublicense any alleged infringer in the Licensed Territory for future use of the Licensed Patents.

     11.8 If LICENSEE pay any amounts in fees, expenses or costs to maintain, prosecute, bring or defend any proceeding relating to any infringement by a third party of any Licensed Patents, any declaratory action alleging invalidity or non-infringement of any Licensed Patents, or any interference, opposition, nullity or revocation proceeding relating to any Licensed Patents pursuant to this Section 11 (the “Section 11 Costs”), TUFTS agrees that 50% of the amount of such Section 11 Costs may be credited as they are incurred by LICENSEE against royalties due to TUFTS under Section 5 of this Agreement.

12 SUBLICENSES

     12.1 LICENSEE may grant sublicenses under the Exclusive Technology to make, have made, import, have imported, use, lease, sell and offer for sale, have sold and otherwise commercialize and exploit Licensed Products, and to practice any method, process or procedure within the Exclusive Technology in the Licensed Territory. The terms and conditions of each sublicense shall be consistent with the terms and conditions of this Agreement and shall contain, among other things (by way of example but not limitation), provisions substantially similar to and consistent with: the “Net Sales” definition; Section 6; Section 7.1 (so that no representations or warranties inconsistent with that Section shall be extended to or by any sublicensee); Section 10; and Section 18.

     12.2 Any sublicense granted by LICENSEE under this Agreement shall remain in effect in the event of any termination of this Agreement and shall provide for the assignment of such sublicense to TUFTS or its designee in the event that this Agreement is terminated; provided, that the financial obligations of each sublicensee to TUFTS shall be limited to the amounts such sublicensee would be obligated to pay to LICENSEE had this Agreement not been terminated.

     12.3 Each sublicense shall provide that the obligations to TUFTS of Sections 6, 7.1, 8.1, 10.1, 11.3, 11.4, 13.4, and 18 shall be binding on the sublicensee and enforceable by both TUFTS and LICENSEE.

-11-

     12.4 LICENSEE shall furnish to TUFTS a true and complete copy of each sublicense agreement and each amendment thereto, promptly after the sublicense or amendment has been agreed upon. TUFTS agrees that it will keep each agreement confidential.

     12.5 No sublicense shall relieve LICENSEE of any of its obligations hereunder, and LICENSEE shall be responsible for the acts or omissions of its Affliliates and sublicensees and for compliance by them with their obligations, and LICENSEE shall take all steps necessary to enforce that compliance to the extent required to allow LICENSEE to fully comply with all of its obligations under this Agreement.

13 TERM AND TERMINATION

     13.1 Unless sooner terminated in a manner provided herein, this Agreement shall continue in force on a country-by-county and Licensed Product-by-Licensed Product basis until the expiration of the last to expire of all Valid Claims in such country included in the Licensed Patents. Following such an expiration, LICENSEE shall have a non-exclusive, royalty-free, irrevocable license in such country, to the Know-How.

     13.2 LICENSEE shall have the right to terminate the Agreement at any time following ninety (90) days written notice to TUFTS. LICENSEE may terminate this Agreement with respect to any country or any Licensed Patent by giving TUFTS notice in writing at least sixty (60) days in advance of the effective date of termination selected by LICENSEE.

     13.3 TUFTS may terminate this Agreement if LICENSEE:

(a)	Is in default in payment of royalty;
(b)	Is in material breach of any provision hereof;

and LICENSEE fails to remedy any such default, or breach, or fails to act reasonably to remedy any default, or breach, within thirty (30) days after receipt of written notice thereof by TUFTS.

     13.4 TUFTS may terminate this Agreement if LICENSEE fails to cure any default on the diligence milestones in Section 4 after a twelve month period commencing upon LICENSEE’s receipt of written notification from TUFTS of LICENSEE’s default of such milestones.

     13.5 Surviving any termination are:

(a)	LICENSEE’s obligation to pay royalties accrued or accruable;
(b)	Any cause of action or claim of LICENSEE or TUFTS, accrued or to accrue, because of any breach or default by the other party; and
(c)	The provisions of Articles 8, 10, 15, 17 and Sections 7.1, 12.2 and 13.4.

-12-

14 ASSIGNMENT

     Neither party may assign this Agreement or any part hereof without the express written consent of the other, which consent shall not be unreasonably withheld; provided, however, LICENSEE may assign this Agreement or any portion hereof to an Affiliate or to a successor of all or substantially all its business relating to the Licensed Patents or Know-How without the written consent of TUFTS and shall provide TUFTS notice of any such assignment. However, no assignment or other transfer by LICENSEE shall relieve LICENSEE of any obligations hereunder and LICENSEE shall continue to be primarily and jointly and severally liable (along with such assignee or other transferee) for the performance of all obligations of LICENSEE and such assignee or other transferee hereunder.

15 ARBITRATION

     15.1 Any controversy arising under or related to this Agreement, and any disputed claim by either party against the other under this Agreement excluding any dispute relating to patent validity or infringement arising under this Agreement, shall be settled by arbitration in accordance with the Rules of Commercial Arbitration of the American Arbitration Association.

     15.2 Upon request by either party, arbitration will be initiated by a third party arbitrator mutually agreed upon in writing by LICENSEE and TUFTS within thirty (30) days of such arbitration request. Judgment upon the award rendered by the arbitrator shall be final and nonappealable and may be entered in a court having jurisdiction thereof. The parties agree that any provision of applicable law notwithstanding, they will not request and the arbitrators shall have no authority to award punitive or exemplary damages against any party. The costs of the arbitration, including administrative fees and fees of the arbitrators shall be shared equally by the parties. Each party shall bear the cost of its own attorneys’ fees and expert fees.

     A. WHEREAS, Landlord and Tenant have entered in that certain Single Tenant Lease dated August 18, 2004 (the “Original Lease”), pursuant to which Tenant leased three (3) parcels of real property located in the City of San Diego, County of San Diego, State of California, legally described as: (1) Parcel 1 of Parcel Map 18286 filed with the San Diego County Recorder on June 21, 1999 (together with any easements and appurtenances thereto, the “Parcel 1 Land”); (2) Parcel 2 of Parcel Map 18286 filed with the San Diego County Recorder on June 21, 1999 (together with any easements and appurtenances thereto, the “Parcel 2 Land” and, together with the Parcel 1 Land, the “Property”); and (3) Parcel 3 of Parcel Map 18286 filed with the San Diego County Recorder on June 21, 1999 (together with any easements and appurtenances thereto, the “Parcel 3 Land” and, collectively with the Parcel 1 Land and the Parcel 2 Land, the “Parcels”). The Property is improved by two (2) buildings consisting of approximately 104,870 square feet of space (the “Buildings”), and the Parcel 3 Land is improved by one (1) building consisting of approximately 11,000 square feet of space (the “Diversified Building”);

     C. WHEREAS, pursuant to the terms and conditions of the Original Lease, Landlord granted Tenant certain rights in connection with the New Parcel 3 Building, including: (1) a right of first refusal to lease space in the New Parcel 3 Building as set forth in Section 25 of the Original Lease, and (2) a development fee in connection with the New Parcel 3 Building as set forth in Section 25 of the Original Lease (the “Tenant’s Development Rights”);

AGREEMENT

     NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, hereby amend and restate the Original Lease, effective from and after the Execution Date, to exclude the Parcel 3 Land (including the Diversified Building) from the “Premises” covered by this Lease, to terminate the Tenant’s Development Rights, and to read in its entirety as follows:

3. Term. The actual term of this Lease (the “Term”) shall be the period from the Execution Date through the Expiration Date, subject to earlier termination of this Lease as provided herein.

4. Possession and Commencement Date.

     4.1. Possession. Tenant hereby acknowledges that immediately prior to the Execution Date, Tenant occupied the Premises and that Tenant is in possession of the Premises, and is familiar with the condition thereof and accepts the Premises in its “as is” condition with all faults, and Landlord makes no representation or warranty of any kind with respect the Premises, and Landlord will have no obligation to improve, alter or repair the Premises, except as specifically set forth herein. Tenant acknowledges that Tenant was the prior owner of the Premises and as such is fully aware of the current conditions of the Premises.

5. Rent.

     5.1. Tenant shall pay to Landlord as Basic Annual Rent for the Premises, the sums set forth in Section 2.3, subject to annual rent adjustments in accordance the provisions of Article 6 hereof. Basic Annual Rent shall be paid in equal monthly installments on or before the first day of the applicable month.

     5.2. In addition to Basic Annual Rent, Tenant shall pay to Landlord as additional rent (“Additional Rent”) at times hereinafter specified in this Lease (a) amounts related to Insurance Costs, Utility Costs and Taxes (each as defined below) and (b) any other amounts that Tenant agrees to pay under the provisions of this Lease that are owed to Landlord, including, without limitation, any and all other sums that may become due by reason of any default of Tenant or failure on Tenant’s part to comply with the agreements, terms, covenants and conditions of this Lease to be performed by Tenant, after notice and the lapse of any applicable cure periods.

     5.3. Basic Annual Rent and Additional Rent shall together be denominated “Rent.” Rent shall be paid to Landlord, without, except as otherwise provided herein, abatement, deduction or offset, in lawful money of the United States of America at the office of Landlord as set forth in Section 2.9 or to such other person or at such other place as Landlord may from time designate in writing.

6. Rent Adjustments. The Basic Annual Rent shall be adjusted as follows:

     6.1. The Basic Annual Rent per rentable square foot of the Premises shall be increased in accordance with Schedule 1 attached hereto.

     6.2. On the first day of each Extended Term (as defined in Section 38), the Basic Annual Rent shall be adjusted in accordance with Section 38.1. During each Extended Term, the Basic Annual Rent per rentable square foot of the Premises shall be increased, on every other anniversary (i.e., the second anniversary, the fourth anniversary, the sixth anniversary, etc.) of the first (1^st) day of each such Extended Term, by five percent (5%) of the Basic Annual Rent immediately preceding such increase.

The monthly installment of Basic Annual Rent that is due for the month in which each such adjustment occurs (the installment due immediately before such month) shall be the first installment that will be increased to reflect such increase in Basic Annual Rent.

7. Taxes.

     7.1. Commencing with the Execution Date and continuing for each calendar year or, at Landlord’s option, tax year (each such “tax year” being a period of twelve (12) consecutive calendar months for which the applicable taxing authority levies or assesses Taxes), for the balance of the Term, Tenant shall pay to Landlord the amount of all Taxes levied and assessed for any such year upon the Premises. “Taxes” shall mean all government impositions including, without limitation, property tax costs consisting of real and personal property taxes and assessments (including amounts due under any improvement bond upon the Premises or any portion thereof, including the Parcel or parcels of real property upon which the Buildings are located or assessments levied in lieu thereof) imposed by any federal, state, regional, local or municipal governmental authority, agency or subdivision (each, a “Governmental Authority”) on the Premises or improvements thereon, any tax on or measured by gross rentals received from the rental of space in the Buildings, or tax based on the square footage of the Premises or the

3

Buildings as well as any parking charges, utilities surcharges, or any other costs levied, assessed or imposed by, or at the direction of, or resulting from statutes or regulations, or interpretations thereof, promulgated by any Governmental Authority in connection with the use or occupancy of the Premises or the parking facilities exclusively serving the Premises; any tax on this transaction or this Lease; provided, however, that “Taxes” shall in no event include any franchise or federal or state income tax, excess profit taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes or any tax based on net rentals received from the rental of space in the Buildings. Any amount paid by Tenant for any partial year of the Term shall be prorated on the basis of the number of days of such partial year. Payment shall be made in the following manner: Tenant shall pay to Landlord the amounts owed under this Article 7 within thirty (30) days after Landlord gives notice to Tenant of the amount of such Taxes payable by Tenant (or not less than fifteen (15) days prior to delinquency, whichever is later). Landlord also shall provide Tenant with a copy of the applicable tax bill or tax statement from the relevant taxing authority. Notwithstanding the foregoing, if Applicable Laws allow any such Taxes to be paid in installments, then Tenant may make such payments to Landlord in installments, provided that each such installment shall be payable to Landlord not less than ten (10) days prior to the date upon which payment of the applicable installment to the taxing authority becomes delinquent. In addition to any other amounts due from Tenant to Landlord, if Tenant fails to pay Taxes to Landlord as herein required, Tenant shall pay to Landlord the amount of any interest, penalties or late charges imposed by any governmental authority for late payment. “Applicable Laws” means all federal, state, municipal and local laws, codes, ordinances, rules and regulations of Governmental Authorities, committees, associations, or other regulatory committees, agencies or governing bodies having jurisdiction over the Premises, Landlord or Tenant, including both statutory and common law and hazard waste rules and regulations.

          7.1.1 Tenant shall have the right, by appropriate proceedings, to protest or contest in good faith any assessment or reassessment of Taxes, any special assessment, or the validity of any Taxes or of any change in assessment or tax rate; provided, however, that prior to any such challenge Tenant must either (a) pay the Taxes alleged to be due in their entirety and seek a refund from the appropriate authority or (b) post a bond in an amount sufficient to ensure full payment of the Taxes, including any potential interest, late charge and penalties. Upon a final determination with respect to any such contest or protest, Tenant shall promptly pay to the appropriate Governmental Authority all sums found to be due with respect thereto. In any such protest or contest, Tenant may act in its own name, and at the request of Tenant, Landlord shall cooperate with Tenant in any way Tenant may reasonably require in connection with such contest or protest, including signing such documents as Tenant reasonably shall request, provided that such cooperation shall be at no expense to Landlord and shall not require Landlord to attend any appeal or other hearing. Any such contest or protest shall be at Tenant’s sole expense, and if any penalties, interest or late charges become payable with respect to the Taxes as a result of such contest or protest, Tenant shall pay the same.

          7.1.2 If Tenant obtains a refund as the result of Tenant’s protest or contest, and subject to Tenant’s obligation to pay Landlord’s costs (if any) associated therewith, Tenant shall be entitled to such refund to the extent it relates to the Premises during the Term.

     7.2. If, at any time during the Term under the laws of any Governmental Authority, a tax or excise on rent or any other tax howsoever described is levied or assessed by any such political body against Landlord on account of rentals payable to Landlord hereunder, such tax or excise shall be considered “Taxes” for the purposes of this Article 7, although any amount assessed against Landlord as state or federal income tax shall not be deemed “Taxes.”

     7.3. To the extent Landlord is required by a lender, Tenant shall timely pay all tax and insurance impound payments due on the Premises.

     7.4. Taxes on Tenant’s Property.

          7.4.1 Tenant shall pay at least twenty (20) days prior to delinquency any and all taxes levied against any personal property or trade fixtures placed by Tenant in or about the Premises.

          7.4.2 If any such taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property or, if the assessed valuation of the Buildings are increased by inclusion therein of a value attributable to Tenant’s personal property or trade

4

fixtures, and if Landlord, after written notice to Tenant, pays the taxes based upon any such increase in the assessed valued of the Buildings, then Tenant shall, upon demand, repay to Landlord the taxes so paid by Landlord.

     7.5. Cut-Off Date. Notwithstanding anything herein to the contrary, Tenant shall not be responsible for Taxes attributable to any calendar year which are first billed to Tenant more than eighteen (18) months after the expiration of the applicable calendar year, except with respect to supplemental Taxes.

8. Security Deposit.

     8.1. Pursuant to the Original Lease, Tenant has deposited with Landlord an amount equal to $1,911,855 as the security deposit under the Original Lease (the “Original Lease Security Deposit”), and (a) from and after the Execution Date, Landlord shall continue to hold a portion of the Original Lease Security Deposit equal to $865,177.50 (the “Security Deposit”) in accordance with the terms and conditions of this Section 8, (b) from and after the Execution Date, Landlord shall hold a portion of the Original Lease Security Deposit equal to $40,836.75 in accordance with the terms and conditions of Section 10 of the Parcel 3 Lease, and (c) Landlord shall return the remaining portion of the Original Lease Security Deposit in an amount equal to $1,005,840.75 to Tenant

     8.2. The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease to be kept and performed by Tenant during the period commencing on the Execution Date and ending upon the expiration or termination of this Lease. If Tenant defaults with respect to any provision of this Lease, including, but not limited to, any provision relating to the payment of Rent, then Landlord may (but shall not be required to) use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default. If any portion of the Security Deposit is so used or applied, then Tenant shall, within twenty (20) days following demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep this Security Deposit separate from its general fund, and Tenant shall not be entitled to interest on the Security Deposit. The provisions of this Article 8 shall survive the expiration or earlier termination of this Lease.

     8.3. In the event of bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings.

     8.4. Landlord may deliver to any purchaser of Landlord’s interest in the Premises the funds deposited hereunder by Tenant, and thereupon Landlord shall be discharged from any further liability with respect to such deposit. This provision shall also apply to any subsequent transfers.

     8.5. If Tenant is not then in Default under this Lease nor is any event then occurring which with the giving of notice or the passage of time, or both, would constitute a Default hereunder, then the Security Deposit, or any balance thereof, shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within thirty (30) days after the expiration or earlier termination of this Lease.

     8.6. The Security Deposit may be in the form of cash, a letter of credit or any other security instrument acceptable to Landlord in its sole discretion. Tenant may at any time, except during Default, deliver a letter of credit (“L/C Security”) as the entire Security Deposit, as follows.

          8.6.1 If Tenant elects to deliver L/C Security, then Tenant shall provide Landlord, and maintain in full force and effect throughout the Term, a letter of credit in substantially the form of Exhibit D issued by an issuer reasonably satisfactory to Landlord, in the amount of the Security Deposit, with an initial term of at least one year. If, at the Expiration Date, any Rent remains uncalculated or unpaid, then: (a) Landlord shall with reasonable diligence complete any necessary calculations; (b) Tenant shall extend the expiry date of such L/C Security from time to time as Landlord reasonably requires; and (c) in such extended period,

5

Landlord shall not unreasonably refuse to consent to an appropriate reduction of the L/C Security. Tenant shall reimburse Landlord’s legal costs (as estimated by Landlord’s counsel) in handling Landlord’s acceptance of L/C Security or its replacement or extension

          8.6.2 If Tenant delivers to Landlord satisfactory L/C Security in place of the entire Security Deposit, Landlord shall promptly remit to Tenant any cash Security Deposit Landlord previously held.

          8.6.3 Landlord may draw upon the L/C Security, and hold and apply the proceeds in the same manner and for the same purposes as the Security Deposit, if: (a) an uncured Default exists; (b) as of the date thirty (30) days before any L/C Security expires (even if such scheduled expiry date is after the Expiration Date) Tenant has not delivered to Landlord an amendment or replacement for such L/C Security, reasonably satisfactory to Landlord, extending the expiry date to the earlier of (i) six (6) months after the then-current Expiration Date or (ii) the date one year after the then-current expiry date of the L/C Security; (c) the L/C Security provides for automatic renewals, Landlord asks the issuer to confirm the current L/C Security expiry date, and the issuer fails to do so within ten (10) business days; (d) Tenant fails to pay (when and as Landlord reasonably requires) any bank charges for Landlord’s transfer of the L/C Security; or (e) the issuer of the L/C Security ceases, or announces that it will cease, to maintain an office in the city where Landlord may present drafts under the L/C Security. This Section does not limit any other provisions of this Lease allowing Landlord to draw the L/C Security under specified circumstances.

          8.6.4 Tenant shall not seek to enjoin, prevent, or otherwise interfere with Landlord’s draw under L/C Security, even if it violates this Lease. Tenant acknowledges that the only effect of a wrongful draw would be to substitute a cash Security Deposit for L/C Security, causing Tenant no legally recognizable damage. Landlord shall hold the proceeds of any draw in the same manner and for the same purposes as a cash Security Deposit. In the event of a wrongful draw, the parties shall cooperate to allow Tenant to post replacement L/C Security simultaneously with the return to Tenant of the wrongfully drawn sums, and Landlord shall upon request confirm in writing to the issuer of the L/C Security that Landlord’s draw was erroneous.

          8.6.5 If Landlord transfers its interest in the Premises, then Tenant shall at Tenant’s expense, within ten (10) business days after receiving a request from Landlord, deliver (and, if the issuer requires, Landlord shall consent to) an amendment to the L/C Security naming Landlord’s grantee as substitute beneficiary; provided, however, in the event Landlord transfers its interest in the Premises more than once in a twelve (12) month period, Landlord shall pay any fee owed to the issuing bank in connection with any such additional transfer. If the required Security changes while L/C Security is in force, then Tenant shall deliver (and, if the issuer requires, Landlord shall consent to) a corresponding amendment to the L/C Security.

9. Use.

     9.1. Tenant shall use the Premises for the purpose set forth in Section 2.7, and shall not use the Premises, or permit or suffer the Premises to be used, for any other purpose without Landlord’s prior written consent, which consent Landlord may withhold in its reasonable discretion.

     9.2. Tenant shall not use or occupy the Premises in violation of Applicable Laws; zoning ordinances; or the certificate of occupancy issued for the Buildings, and shall, upon five (5) days’ written notice from Landlord, discontinue any use of the Premises that is declared or claimed by any Governmental Authority having jurisdiction to be a violation of any of the above, or that Landlord has a reasonable basis to believe that such use violates any of the above and Landlord identifies such basis in its notice to Tenant. Tenant shall comply with any direction of any Governmental Authority having jurisdiction that shall, by reason of the nature of Tenant’s use or occupancy of the Premises, impose any duty upon Tenant with respect to the Premises or with respect to the use or occupation thereof.

     9.3. Tenant shall not do or permit to be done anything that will invalidate or increase the cost of any fire, environmental, extended coverage or any other insurance policy covering the Premises, and shall comply with all rules, orders, regulations and requirements of the insurers of the Premises, and Tenant shall promptly, upon demand, reimburse Landlord for any additional premium charged for such policy by reason of Tenant’s failure to comply with the provisions of this Article 9.

6

     9.4. Tenant shall, at its sole cost and expense, promptly and properly observe and comply with all present and future orders, regulations, directions, rules, laws, ordinances, and requirements of all Governmental Authorities (including, without limitation, state, municipal, county and federal governments and their departments, bureaus, boards and officials) arising from the use or occupancy of the Premises, including, without limitation, the requirements of Americans with Disabilities Act of 1990 (together with regulations promulgated pursuant thereto, the “ADA”). Tenant’s obligations under this Section 9.4 shall include any alterations to the Premises that Tenant is required or elects to make pursuant to the terms of this Lease.

     9.5. Tenant shall keep all doors opening onto public corridors closed, except when in use for ingress and egress.

     9.6. No additional locks or bolts of any kind shall be placed upon any of the doors or windows by Tenant, nor shall any changes be made to existing locks or the mechanisms thereof without Landlord’s prior written consent. Tenant shall, upon termination of this Lease, return to Landlord all keys to offices and restrooms either furnished to or otherwise procured by Tenant. In the event any key so furnished to Tenant is lost, Tenant shall pay to Landlord the cost of replacing the same or of changing the lock or locks opened by such lost key if Landlord shall deem it necessary to make such change

     9.7. No awnings or other projections shall be attached to any outside wall of the Buildings. No curtains, blinds, shades or screens shall be attached to or hung in, or used in connection with, any window or door of the Premises other than Landlord’s standard window coverings. Neither the interior nor exterior of any windows shall be coated or otherwise sunscreened without Landlord’s prior written consent, nor shall any bottles, parcels or other articles be placed on the windowsills. No equipment, furniture or other items of personal property shall be placed on any exterior balcony without Landlord’s prior written consent.

     9.8. Tenant shall, at Tenant’s sole cost and expense, have the exclusive right to install the maximum amount of any legally permitted signage on the Premises (including any building thereon) (“Signage”), which Signage shall be subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Tenant shall keep the Signage in good condition and repair. The size, design, and other physical aspects of any sign shall be subject to Landlord’s written approval prior to installation, which approval will not unreasonably be withheld, any covenants, conditions, or restrictions encumbering the Premises and, any Applicable Laws. The cost of the sign(s), including but not limited to the permitting, installation, maintenance and removal thereof shall be at Tenant’s sole cost and expense. If Tenant fails to maintain its sign(s), or if Tenant fails to remove such sign(s) upon termination of this Lease, or fails to repair any damage caused by such removal (including without limitation, painting the damaged portions of the Buildings and any other portions of the Buildings that Landlord reasonably determines in good faith shall be painted so that repainting the damaged portion of the Buildings does not adversely affect the visual appearance of the Buildings, if required by Landlord; provided, however, in no event shall Landlord require Tenant to repaint an entire Building), Landlord may do so at Tenant’s expense. Tenant shall on demand reimburse Landlord for all costs incurred by Landlord to effect such removal, which amounts shall be deemed Additional Rent and shall include without limitation, all sums disbursed, incurred or deposited by Landlord, including Landlord’s costs, expenses and actual attorneys’ fees with interest thereon. Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising directly or indirectly out of Tenant’s failure to perform any of its obligations under this Section 9.8. By executing this Lease, Landlord hereby approves the signage currently existing on the Premises.

     9.9. Tenant shall only place equipment within the Premises with floor loading consistent with the structural design of the Buildings without Landlord’s prior written approval, and such equipment shall be placed in a location designed to carry the weight of such equipment.

7

     9.10. Tenant shall not (a) use or allow the Premises to be used for any unlawful or reasonably objectionable purposes or (b) cause, maintain or permit any nuisance or waste in, on or about the Premises.

     9.11. Notwithstanding any other provision herein to the contrary, Tenant shall be responsible for all liabilities, costs and expenses arising out of or in connection with the compliance of the Premises with the ADA, and Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising out of any failure of the Premises to comply with the ADA. The provisions of this Section 9.11 shall survive the expiration or earlier termination of this Lease.

10. Brokers.

     10.1. Tenant represents and warrants that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease other than Steve Rosetta and Ted Simpson, Cushman & Wakefield (“Tenant’s Broker”), and that it knows of no other real estate broker or agent that is or might be entitled to a commission in connection with this Lease. Landlord shall compensate Tenant’s Broker in relation to this Lease pursuant to a separate agreement between Landlord and Landlord’s Broker (the “Commission Agreement”).

     10.2. Landlord represents and warrants that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease other than Doug Lozier at CB Richard Ellis, Inc. (“Landlord’s Broker”), and that it knows of no other real estate broker or agent that is or might be entitled to a commission in connection with this Lease. Landlord shall compensate Landlord’s Broker in relation to this Lease pursuant to the Commission Agreement.

     10.3.

     10.4. Tenant agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any other broker or agent, other than Tenant’s Broker, employed or engaged by it or claiming to have been employed or engaged by Tenant. Landlord agrees to indemnify, defend and hold Tenant harmless from any and all cost or liability for compensation claimed by any other broker or agent, other than Landlord’s Broker, employed or engaged by it or claiming to have been employed or engaged by Landlord.

11. Holding Over.

     11.1. If, with Landlord’s prior written consent, Tenant holds possession of all or any part of the Premises after the Term, Tenant shall become a tenant from month to month after the expiration or earlier termination of the Term, and in such case Tenant shall continue to pay (a) the Basic Annual Rent in accordance with Article 5, as adjusted in accordance with Article 6, and (b) any amounts for which Tenant would otherwise be liable under this Lease if this Lease were still in effect, including, without limitation, payments for Taxes and insurance. Any such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein.

     11.2. Notwithstanding the foregoing, if Tenant remains in possession of the Premises after the expiration or earlier termination of the Term without Landlord’s prior written consent, Tenant shall become a tenant at sufferance subject to the terms and conditions of this Lease, except that the per diem Basic Annual Rent shall be equal to: (a) for the first three (3) months that Tenant remains in possession of the Premises after the expiration or earlier termination of this Lease, one hundred twenty-five percent (125%) of the Basic Annual Rent in effect during the last thirty (30) days of the Term; and (b) for any time thereafter that Tenant remains in possession of the Premises after the expiration or earlier termination of this Lease, one hundred fifty percent (150%) of the Basic Annual Rent in effect during the last thirty (30) days of the Term.

     11.3. Acceptance by Landlord of Rent after the expiration or earlier termination of the Term shall not result in an extension, renewal or reinstatement of this Lease.

     14.1. Rules and Regulations.

          14.2.1 Tenant shall have the right to use the fitness center, the full court basketball/sports courts, outdoor seating areas, dressing, locker and working rooms, restrooms, and showers located on the Parcel 3 Land (collectively, the “Recreation Facilities”) pursuant to the terms and conditions of the Reciprocal Easement Agreement attached hereto as Exhibit F (the “REA”).

          14.2.2 Tenant shall, at Tenant’s sole cost and expense, comply with the terms and conditions set forth in, and perform each of the obligations of the Parcels 1&2 Owner (as defined in the REA) described in, Sections 2, 4.1, 4.2, 4.3, 4.4, 4.8, 7, 8, 9, 11.3, 11.10, 11.11 and 11.12 of the REA in accordance with the terms of conditions of the REA as if Tenant were the Parcels 1&2 Owner.

          14.2.3 Tenant shall, and shall cause Tenant’s Agents to, faithfully observe and comply with any rules and regulations adopted pursuant to Section 4.7 of the REA (the “Recreation Facilities Rules and Regulations”). The Parcel 3 Owner (as defined in the REA) has the right to refuse to allow Tenant’s Agents to access the Recreation Facilities if such Tenant’s Agent has not complied with the applicable Recreation Facilities Rules and Regulations after receiving written notice of such failure to comply.

          14.2.4 Notwithstanding anything to the contrary in this Lease, Landlord shall have no responsibility to Tenant or Tenant’s Agents (as defined below), for any accidents, claims, demands, liabilities, causes of action, judgments, costs, liens, damages, injuries, suits, losses or expenses, including attorneys’ fees, of any nature, kind or description, arising out of, caused by, or resulting from Tenant or Tenant’s Agent’s use of the Recreational Facilities or the negligence of Landlord Parties (as defined in Section 19.3) or Tenant’s Agents in connection with the operation and maintenance of such Recreational Facilities.

          14.2.5 So long as this Lease is in full force and effect, Landlord shall not amend or modify the REA without first obtaining: (a) the prior written consent of the original Tenant hereunder (but not any assignee or subtenant), which consent shall not be unreasonably withheld, conditioned or delayed, and (b) solely with respect to amendments or modifications that could reasonably be expected to have a material adverse effect on obligations assumed by any successors and assigns of Tenant under the REA, the prior written consent of any such successors and assigns, which consent shall not be unreasonably withheld, conditioned or delayed. All amendments or modifications which result in an increase of the costs and expenses to be incurred by Tenant under Section 14.2.2 shall be deemed material and adverse.

     14.3. Parking.

          14.3.1 Before Landlord commences construction of the New Parcel 3 Building, Landlord shall coordinate and discuss with Tenant necessary restrictions to the parking spaces located on the Property in connection with the construction of the New Parcel 3 Building. Landlord shall have the right to remove or relocate parking spaces on the Property and temporarily erect barricades which are reasonably necessary, as determined by Landlord, for security and/or safety purposes in connection with the construction of the New Parcel 3 Building, or are otherwise permitted in accordance with Section 14.4 hereof.

          14.3.2 From the Execution Date through the Substantial Completion (as defined in the Parcel 3 Lease) of the New Parcel 3 Building, Tenant shall have the right to use, at no additional cost, (i) subject to Section 14.3.1, any parking spaces located on the Property which are not affected by the construction on the New Parcel 3 Building, and (ii) subject to Section 14.3.1 and the rights of Diversified under the Diversified Lease, any parking spaces located in the Temporary Parking Easement (as defined in the REA) pursuant to, and in accordance with, the terms and conditions of the REA. Furthermore, should Tenant require additional parking other than as set forth above, Landlord and Tenant will work together to determine a parking solution that is acceptable to both parties (which may include Landlord obtaining off-site parking for Tenant).

          14.3.3 From and after the Substantial Completion of the New Parcel 3 Building, Tenant shall have the right to use, at no additional cost, the parking facilities serving the Premises, which shall include, (i) 277 spaces located on the Property (the “Parcels 1&2 Parking Spaces”), and (ii) 40 spaces located on the Parcel 3 Land pursuant to, and in accordance with, the terms and conditions of the REA. Tenant shall maintain the Parcels 1&2 Parking Spaces in accordance with Section 17. Tenant shall maintain the Parcels 1&2 Parking Spaces and shall not reduce the number of Parcels 1&2 Parking Spaces below the number referenced in clause (i) above.

15. Utilities and Services.

     15.1. Tenant shall, at Tenant’s sole cost and expense, procure and maintain contracts, with copies furnished promptly to Landlord after execution thereof, in customary form and substance for, and with contractors specializing and experienced in, the maintenance of the following equipment and improvements, if any, if and when installed on the Premises (a) HVAC equipment, (b) boilers and pressure vessels, (c) fire extinguishing systems, including fire alarm and smoke detection devices, (d) landscaping and irrigation systems, (e) roof coverings and drains, (f) clarifiers, (g) basic utility feeds to the perimeter of the Buildings; and (h) any other equipment reasonably required by Landlord. Notwithstanding the foregoing, in the event Tenant fails to maintain the contracts required under this Section 15.1 within one (1) business day after Landlord provides Tenant written notice of such failure, Landlord reserves the right, upon notice to Tenant, to procure and maintain any or all of such contracts, and if Landlord so elects, Tenant shall reimburse Landlord, upon demand, for the actual documented costs thereof.

     15.2. Within sixty (60) days after the Execution Date, and within sixty (60) days after the beginning of each calendar year during the Term, Landlord shall give Tenant a written estimate for such calendar year of the cost of utilities, if not separately metered (“Utility Costs”), insurance provided by Landlord (“Insurance Costs”). Tenant shall pay such estimated amount to Landlord in advance in equal monthly installments. Within ninety (90) days after the end of each calendar year, Landlord shall furnish to Tenant a statement showing in reasonable detail the costs incurred by Landlord for Utility Costs and Insurance Costs for the Premises during such year (the “Annual Statement”), and Tenant shall pay to Landlord the costs incurred in excess of the payments previously made by Tenant within thirty (30) days of receipt of the Annual Statement. In the event that the payments previously made by Tenant for Utility Costs and Insurance Costs for the Premises exceed Tenant’s obligation, such excess amount shall be credited by Landlord to the Rent or other charges next due and owing, provided that, if the Term has expired, Landlord shall remit such excess amount to Tenant. In the event Tenant disputes the amounts of any Annual Statement for the particular calendar year delivered by Landlord to Tenant and Tenant is not in Default hereunder, Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have Tenant’s authorized employees inspect, at Landlord’s office in San Diego County during normal business hours, Landlord’s books, records and supporting documents concerning the expenses set forth in such Annual Statement; provided, however, Tenant shall have no right to conduct such inspection, have an audit performed by the Accountant as described below, or object to or otherwise dispute the amount of the expenses set

10

forth in any such Annual Statement unless Tenant notifies Landlord of such objection and dispute, completes such inspection, and has the Accountant commence and complete such audit within one hundred and eighty (180) days immediately following Landlord’s delivery of the particular Annual Statement in question (the “Review Period”); provided, further, that notwithstanding any such timely objection, dispute, inspection, and/or audit, and as a condition precedent to Tenant’s exercise of its right of objection, dispute, inspection and/or audit as set forth in this Section 15.2, Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts as required by the provisions of this Lease in accordance with such Annual Statement. However, such payment may be made under protest pending the outcome of any audit which may be performed by the Accountant as described below. In connection with any such inspection by Tenant, Landlord and Tenant shall reasonably cooperate with each other so that such inspection can be performed pursuant to a mutually acceptable schedule. If after such inspection and/or request for documentation, Tenant still disputes the amount of the expenses set forth in the Annual Statement, Tenant shall have the right, within the Review Period, to cause an independent certified public accountant selected by Tenant and compensated on a non-contingency fee basis (the “Accountant”) to complete an audit of Landlord’s books and records to determine the proper amount of the expenses incurred and amounts payable by Tenant for the calendar year which is the subject of such Annual Statement. Such audit by the Accountant shall be final and binding upon Landlord and Tenant. If such audit reveals that Landlord has over-charged Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is subsequently determined that Landlord’s original Annual Statement which was the subject of such audit overstated expenses by five percent (5%) or more of the actual expenses which were the subject of such audit. The payment by Tenant of any amounts pursuant to this Section 15.2 shall not preclude Tenant from questioning, during the Review Period, the correctness of the particular Annual Statement in question provided by Landlord, but the failure of Tenant to object thereto, conduct and complete its inspection and have the Accountant conduct the audit as described above prior to the expiration of the Review Period for such Annual Statement shall be conclusively deemed Tenant’s approval of the Annual Statement in question and the amount of expenses shown thereon. If following Tenant’s delivery to Landlord of a written request to make Landlord’s books and records regarding the expenses reasonably available to Tenant and/or the Accountant to conduct any such inspection and/or audit described above in this Section 15.2, Landlord fails to make Landlord’s books reasonably available for such purposes during Landlord’s normal business hours, and such failure continues for five (5) business days after Tenant notifies Landlord thereof, then the Review Period shall be extended one (1) day for each such additional day that Tenant and/or the Accountant, as the case may be, is so prevented from accessing such books and records. In connection with any inspection and/or audit conducted by Tenant pursuant to this Section 15.2, Tenant agrees to keep, and to cause all of Tenant’s employees and consultants and the Accountant to keep, all of Landlord’s books and records and the audit, and all information pertaining thereto and the results thereof, strictly confidential (except if required by any court to disclose such information or if such information is available from an inspection of public records).

     15.3. Tenant shall make all arrangements for and pay for all water, sewer, gas, heat, light, power, telephone service and any other service or utility Tenant required at the Premises. Landlord shall not be liable for, nor shall any eviction of Tenant result from, the failure to furnish any utility or service, whether or not such failure is caused by Force Majeure (as defined below) or Landlord’s inability, despite the exercise of reasonable diligence, to furnish any such utility or service. In the event of such failure, Tenant shall not be entitled to termination of this Lease, any abatement or reduction of Rent, or relief from the operation of any covenant or agreement of this Lease. Tenant shall pay for, prior to delinquency of payment therefor, any utilities and services that may be furnished to the Premises during or, if Tenant occupies the Premises after the expiration or earlier termination of the Term, after the Term.

     15.4. Notwithstanding the foregoing and subject to Sections 14.3 and 31, if because of (i) any repair, maintenance, alteration, development or construction performed by Landlord on the Premises after the Commencement Date, which substantially interferes with Tenant’s use of the Premises and which was not caused by Tenant, (ii) any material interference by Landlord with Tenant’s access to the Premises (including the parking facilities) that is not caused by

11

Tenant, or (iii) the presence of Hazardous Materials in, on or around the Premises in connection with the Landlord’s Construction Work or the Tenant Improvements (each as defined in the Parcel 3 Lease) which (a) is not caused by Tenant, and (b) poses a health risk to occupants of the Premises (each, an “Adverse Condition”), Tenant is unable to conduct its business in a reasonable manner in a material portion of the Premises as a direct result of the Adverse Condition and Tenant therefore actually does not occupy or use such portion of the Premises, as the case may be, and such condition persists for more than the “Interruption Period” (as defined below), then following the Interruption Period, Tenant shall be entitled to an abatement of Rent for the portion of the Premises rendered untenantable. However, in the event that the remaining portion of the Premises is not sufficient to allow Tenant to conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Interruption Period during which Tenant is so prevented from effectively conducting its business therein, the Rent for the entire Premises shall be abated; provided, however, if Tenant continues to occupy any portion of the Premises, or reoccupies and conducts its business from any portion of the Premises, during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date such business operations commence. Such abatement shall commence as of the first day after the expiration of the “Interruption Period” and terminate upon the cessation of such Adverse Condition. As used herein, the term “Interruption Period” shall mean seven (7) consecutive business days after written notice thereof to Landlord, or such shorter period as applicable under the coverage which is or would be covered by rental abatement insurance required to be carried by Landlord.

16. Alterations.

     16.1. Tenant shall make no alterations, additions or improvements in or to the Premises or engage in any construction, demolition, reconstruction, renovation, or other work of any kind in, at, or serving the Premises (“Alterations”) without Landlord’s prior written approval, which approval Landlord may withhold in its sole and absolute discretion; provided, however, that Landlord’s approval shall not be unreasonably withheld, conditioned or delayed in connection with any Alteration that does none of the following (i) adversely affects the exterior appearance of a Building or the Premises, (ii) adversely affects the structural aspects of a Building, including, without limitation, the roof, foundation, load bearing walls and structural elements of the Premises, (iii) adversely affects any base-building system or equipment, including, without limitation, the base building HVAC, mechanical, electrical, plumbing or life safety systems; (iv) creates a foreseeable risk of violating any Applicable Law or increasing insurance premiums; (v) violates any recorded document affecting the Premises; (vi) causes a Building to be inconsistent with the quality and scope of a class “A” office buildings in the vicinity of the Buildings; (vii) involves a use of the Premises that is inconsistent with the current use of the Premises; nor (viii) in Landlord’s reasonable judgment, reduces the quality or value of a Building or the Premises (each, a “Design Problem”). In seeking Landlord’s approval, Tenant shall provide Landlord, at least ten (10) business days in advance of any proposed construction, with plans, specifications, bid proposals, work contracts, requests for laydown areas and such other information concerning the nature and cost of the Alterations as Landlord may reasonably request.

     16.2. Notwithstanding the provisions of Section 16.1, Tenant may make non-structural Alterations to the Premises (“Acceptable Changes”) upon at least ten (10) business days prior written notice to Landlord but without Landlord’s prior consent provided (a) the Acceptable Changes do not involve Design Problems; and (b) the cost of such Acceptable Changes do not exceed Fifty Thousand Dollars ($50,000) per occurrence or an aggregate amount of One Hundred Thousand Dollars ($100,000) in any twelve (12) month period.

     16.3. All Alterations made by Tenant shall be: (a) performed in a good and workmanlike manner and in conformance with any and all Applicable Laws and CC&Rs; and (b) shall be made only by a licensed, bonded contractor and such architects, suppliers and mechanics approved in advance by Landlord (which shall not be unreasonably withheld, conditioned or delayed); provided, however, that such contractor need not be bonded or approved and such architects, suppliers and mechanics need not be approved by Landlord in connection with Acceptable Changes.

     16.4. Tenant shall not construct or permit to be constructed partitions or other obstructions that will interfere with free access to mechanical installation or service facilities of the Buildings, or interfere with the moving of Landlord’s equipment to or from the enclosures containing such installations or facilities.

12

     16.5. Tenant shall accomplish any work performed on the Premises in such a manner as to permit any fire sprinkler system and fire water supply lines to remain fully operable at all times.

     16.6. Tenant covenants and agrees that all work done by Tenant or Tenant’s contractors shall be performed in full compliance with Applicable Laws. Within thirty (30) days after completion of any Alterations, Tenant shall provide Landlord with complete “as-built” drawing print sets and electronic CADD files on disc (or files in such other current format in common use as Landlord reasonably approves or requires) showing any changes in the Premises (but only if drawings and plans were required by this Lease or were prepared in connection with any such Alterations).

     16.7. Before commencing any work, Tenant shall give Landlord at least ten (10) business days’ prior written notice of the proposed commencement of such work.

     16.8. Except for those items listed on Exhibit A, all Alterations, attached equipment, decorations, fixtures, trade fixtures, additions and improvements, subject to Section 16.8, attached to or built into the Premises, made by either of the Parties, including, without limitation, all floor and wall coverings, built-in cabinet work and paneling, sinks and related plumbing fixtures, laboratory benches, exterior venting fume hoods and walk-in freezers and refrigerators, ductwork, conduits, electrical panels and circuits shall (unless, prior to such construction or installation, Landlord elects otherwise) become the property of Landlord upon the expiration or earlier termination of the Term, and shall remain upon and be surrendered with the Premises as a part thereof. The Premises shall at all times remain the property of Landlord and shall be surrendered to Landlord upon the expiration or earlier termination of this Lease. Except for those items on Exhibit A, all trade fixtures, Alterations and Signage installed by or under Tenant shall be the property of Landlord. Notwithstanding the foregoing, at any time during the Term, subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, Tenant shall have the right to update Exhibit A.

     16.9. Tenant shall repair any damage to the Premises caused by Tenant’s removal of any property from the Premises. During any such restoration period, Tenant shall pay Rent to Landlord as provided herein as if the affected portion of the Premises were otherwise occupied by Tenant. The provisions of this Section shall survive the expiration or earlier termination of this Lease.

     16.10. Except as to those items listed on Exhibit A attached hereto, all business and trade fixtures, machinery and equipment, built-in furniture and cabinets, together with all additions and accessories thereto, attached to or built into the Premises shall be and remain the property of Landlord and shall not be moved by Tenant at any time during the Term. If Tenant shall fail to remove any of its effects from the Premises within ten (10) days after the termination of this Lease, then Landlord may, at its option, remove the same in any manner that Landlord shall choose and store said effects without liability to Tenant for loss thereof or damage thereto, and Tenant shall pay Landlord, upon demand, any actual, documented and reasonable costs and expenses incurred due to such removal and storage or Landlord may, at its sole option and upon notice to Tenant, sell such property or any portion thereof at private sale and without legal process for such price as Landlord may obtain and apply the proceeds of such sale against any (a) amounts due by Tenant to Landlord under this Lease and (b) any actual and documented expenses incident to the removal, storage and sale of said personal property.

     16.11. Notwithstanding any other provision of this Article 16 to the contrary, in no event shall Tenant remove any improvement from the Premises as to which Landlord contributed payment without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion.

     16.12. Tenant shall pay to Landlord an amount equal to one and one-half percent (1.5%) of the cost to Tenant of all Alterations installed by Tenant or its contractors or agents to cover Landlord’s overhead and expenses for plan review, coordination, scheduling and supervision thereof but only for those Alterations requiring Landlord’s consent. For purposes of payment of such sum, Tenant shall submit to Landlord copies of all bills, invoices and statements covering

13

the costs of such charges, accompanied by payment to Landlord of the fee set forth in this Section. Tenant shall reimburse Landlord for any extra expenses incurred by Landlord by reason of faulty work done by Tenant or its contractors.

     16.13. Upon Landlord’s written request, within sixty (60) days after final completion of any Alterations performed by Tenant with respect to the Premises, Tenant shall submit to Landlord documentation showing the amounts expended by Tenant with respect to such Alterations, together with supporting documentation reasonably acceptable to Landlord.

     16.14. Tenant shall require its contractors and subcontractors performing work on the Premises to name Landlord and its affiliates and lenders as additional insureds on their respective insurance policies.

17. Repairs and Maintenance.

     17.1. Subject to Landlord’s obligations hereunder, Tenant, at its sole cost and expense, shall maintain and keep the Premises, all improvements thereon, and all appurtenances thereto, including but not limited to sidewalks, parking areas, curbs, roads, driveways, lighting standards, landscaping, sewers, water, gas and electrical distribution systems and facilities, drainage facilities, and all signs, both illuminated and non-illuminated that are now or hereafter on the Premises, in good condition and in a manner consistent with the Permitted Use. Tenant shall make all repairs, replacements and improvements, including, without limitation, all HVAC, plumbing and electrical repairs, replacements and improvements required, and shall keep the same free and clear from all rubbish and debris, excluding, however, the foundation, slab, structural portions of the walls and roof (not including the membrane), and structural steel aspects of the Buildings. All repairs made by Tenant shall be at least equal in quality to the original work, and shall be made only by a licensed, bonded contractor approved in advance by Landlord (which shall not be unreasonably withheld, conditioned or delayed); provided, however, that such contractor need not be bonded or approved by Landlord if the non-structural alterations, repairs, additions or improvements to be performed do not exceed Fifty Thousand Dollars ($50,000) per occurrence or an aggregate amount of One Hundred Thousand Dollars ($100,000) in any twelve (12) month period. Tenant shall not take or omit to take any action, the taking or omission of which shall cause waste, damage or injury to the Premises. Tenant shall indemnify, defend (by legal counsel acceptable to Landlord) and hold harmless Landlord from and against any and all Claims (as defined below) arising out of the failure of Tenant or Tenant’s Agents to perform the covenants contained in this Section. “Tenant’s Agents” shall be defined to include Tenant’s officers, employees, agents, contractors, invitees, customers and subcontractors.

     17.2. Tenant shall maintain the lines designating the parking spaces in good condition and paint the same as often as may be necessary, so that they are easily discernable at all times; resurface the parking areas as necessary to maintain them in good condition; paint any exterior portions of the Buildings as necessary to maintain them in good condition; maintain the roof and landscaping in good condition; maintain sightly screens, barricades or enclosures around any waste or storage areas; and take all reasonable precautions to insure that the drainage facilities of the roof are not clogged and are in good and operable condition at all times

     17.3. There shall be no abatement of Rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the Tenant’s making of any repairs, alterations or improvements in or to any portion of the Premises, or in or to improvements, fixtures, equipment and personal property therein (unless the necessity for any of the same is due to Landlord’s gross negligence or willful misconduct).

     17.4. During the Term, Landlord shall, at Landlord’s sole cost and expense, be responsible for any and all repairs and replacements to the foundation, slab, structural portions of the walls and roof (not including the membrane), and structural steel aspects of the Buildings only. Notwithstanding the foregoing, Tenant shall be responsible for, and shall pay, all costs and expenses of such repair and replacement if such repair or replacement results from anything done by Tenant or Tenant’s Agents or any breach by Tenant under this Lease. For purposes of clarity, except as provided in the preceding sentence, Landlord shall not be responsible for any repairs or replacements to the roof, the exterior walls or any other portions of the Premises. Except for the foregoing and except as otherwise provided in this Lease, Landlord shall not be required to maintain or make any repairs or replacements of any nature or description whatsoever to the Premises unless the necessity for such repairs or replacements is due to Landlord’s gross

14

negligence or willful misconduct. Except as otherwise provided in this Lease, Tenant hereby expressly waives the right to make repairs at the expense of Landlord as provided for in any Applicable Laws in effect at the time of execution of this Lease, or in any other Applicable Laws that may hereafter be enacted, and waives its rights under Applicable Laws relating to a landlord’s duty to maintain its premises in a tenantable condition. Notwithstanding the foregoing, if Tenant shall fail, where such failure shall continue for a period of ten (10) days after written notice thereof from Landlord to Tenant, to maintain or to commence and thereafter to proceed with diligence to make any repair required of it pursuant to the terms of this Lease, Landlord, without being under any obligation to do so and without thereby waiving such default by Tenant, may so maintain or make such repair and may charge Tenant for the actual and documented costs thereof. Any expense reasonably incurred by Landlord in connection with the making of such repairs may be billed by Landlord to Tenant monthly or, at Landlord’s option, immediately, and shall be due and payable within thirty (30) days after such billing.

     17.5. Landlord and Landlord’s agents shall have the right to enter upon the Premises or any portion thereof in accordance with the terms and conditions of Section 30, for the purposes of performing any repairs or maintenance Landlord is permitted or required to make pursuant to this Lease, and of ascertaining the condition of the Premises or whether Tenant is observing and performing Tenant’s obligations hereunder, all without unreasonable interference from Tenant or Tenant’s Agents.

     17.6. Tenant shall, upon the expiration or sooner termination of the Term, surrender the Premises to Landlord in as good of a condition as when received, ordinary wear and tear and damage by casualty excepted. Landlord shall have no obligation to alter, remodel, improve, repair, decorate or paint the Premises or any part thereof, other than pursuant to the terms and provisions of this Lease.

     17.7. Tenant shall, at its sole cost and expense, perform the maintenance and repair obligations of the Parcels 1&2 Owner (as defined in the REA) pursuant to, and in accordance with, Section 4.1 of the REA.

     17.8. Landlord shall not be liable for any failure to make any repairs or to perform any maintenance that is an obligation of Landlord unless such failure shall persist for an unreasonable time after Tenant provides Landlord with written notice of the need of such repairs or maintenance. Notwithstanding any provision in this Lease to the contrary, if Tenant provides notice to Landlord of an event or circumstance which requires the action of Landlord with respect to the provision of repairs as set forth in Section 17.4 of this Lease, and Landlord fails to provide such action as required by the terms of this Lease within thirty (30) days after the date of such notice from Tenant (or if such repair is reasonably expected to require longer than thirty (30) days to complete, if Landlord shall fail to commence in a meaningful way such repair within said thirty (30) day period and diligently prosecutes such repair to completion), then Tenant may provide Landlord with a second written notice stating in bold and all caps 12 point font that “Landlord’s failure to commence repair of the damage described below within ten (10) business days after Landlord’s receipt of this second notice shall entitle Tenant to repair such damage.” If Landlord does not commence in a meaningful way such repair within such ten (10) business day period, then Tenant shall have the right to take such action, and if such action was required under the terms of this Lease to be taken by Landlord, then Tenant shall be entitled to reimbursement by Landlord of Tenant’s reasonable actual and documented costs and expenses in taking such action. Notwithstanding the foregoing, in case of an emergency (where there is an imminent threat of injury to persons or damage to property), Tenant shall only be required to provide Landlord five (5) business days notice of the need to make such repairs stating in bold and all caps 12 point font that “EMERGENCY: Landlord’s failure to commence its repairs of such damage within five (5) business days after Landlord’s receipt of this notice shall entitle Tenant to repair such damage,” and if Landlord does not commence in a meaningful way such repair within such five (5) business day period, then Tenant shall have the right to take such action. In the event Tenant takes such action, and such work will affect the building systems and equipment, structural integrity of the Buildings or exterior appearance of the Buildings, Tenant shall use Reno Construction for such work unless Reno Construction is unwilling or unable to perform such work or its pricing is unreasonable, in which event Tenant may utilize the services of any other qualified contractor which normally and regularly performs similar work in comparable first-class, institutional quality, office buildings in the San Diego, California area whose pricing is reasonable. If Tenant is entitled to reimbursement by Landlord of Tenant’s reasonable actual and documented costs and expenses in taking any action pursuant to this

15

Section 17.8, Tenant shall so notify Landlord in writing (the “Reimbursement Notice”), which Reimbursement Notice shall specify in detail such costs and expenses. Within thirty (30) days after Landlord’s receipt of a Reimbursement Notice, Landlord shall pay to Tenant any undisputed portion of such costs and expenses and shall notify Tenant in writing of those costs and expenses specified by Tenant in the Reimbursement Notice which Landlord disputes (the “Disputed Amounts”) and the reasons for such dispute. Any amounts which are not so identified by Landlord as Disputed Amounts within said thirty (30) day period shall be considered to be undisputed. To the extent Landlord fails to reimburse Tenant for the actual and documented costs and expenses specified in the Reimbursement Notice within thirty (30) days after demand therefor, Tenant shall be entitled to offset the sum of the amount of any undisputed portion of such costs and expenses against Basic Annual Rent payable by Tenant under this Lease together with interest at the interest rate of eight percent (8%) per annum from the date of expiration of said thirty (30) day period until the earlier of (a) the date that Landlord reimburses Tenant such amount and (b) the date of offset (up to a maximum offset each month of fifteen percent (15%) of the Basic Annual Rent payable for the Premises) until the full pre-judgment offset amount (plus such interest) has been so offset. If Tenant obtains a final judgment against Landlord for the Disputed Amount and if Landlord fails to pay such judgment within thirty (30) days after the date such judgment is rendered, Tenant shall be entitled to offset such judgment against Basic Annual Rent payable by Tenant under this Lease together with interest at the interest rate of eight percent (8%) per annum from the date Landlord failed to timely reimburse Tenant for such costs and expenses until the earlier of (y) the date that Landlord has reimburses Tenant such amount and (z) the date of offset (up to a maximum offset each month of fifteen percent (15%) of the Basic Annual Rent payable for the Premises) until the full amount of such judgment (plus such interest) has been so offset. If Landlord obtains a final judgment against Tenant for the Disputed Amount, Tenant shall pay to Landlord such judgment within thirty (30) days after the date such judgment is rendered.

     17.9. This Article 17 relates to repairs and maintenance arising in the ordinary course of operation of the Premises and any related facilities. In the event of fire, earthquake, flood, vandalism, war, terrorism, natural disaster or similar cause of damage or destruction, Article 21 shall apply in lieu of this Article 17.

     17.10. Notwithstanding anything above to the contrary, if during the Term, any portion of the Premises which is Tenant’s responsibility hereunder to repair cannot be repaired other than at a cost which is in excess of fifty percent (50%) of the cost of replacing such item(s), then such item(s) shall be replaced by Tenant (subject to Landlord’s prior approval of the plans and specifications and the cost of any such replacement), and Landlord shall reimburse Tenant a prorata share of the cost thereof based upon a fraction, the numerator of which is the number of months of the useful life of such replacement item beyond the expiration of the Term (including any Extended Term, if applicable), and the denominator of which is the total number of months of the useful life of such replacement (as such useful life is specified pursuant to Federal income tax regulations or guidelines for depreciation thereof); provided, however, for purposes of calculating the useful life of such replacement, the useful life of such replacement shall not exceed seven (7) years from the date that such replacement is made.

18. Liens.

     18.1. Subject to the immediately succeeding sentence, Tenant shall keep the Premises free from any liens arising out of work performed, materials furnished or obligations incurred by Tenant. Tenant further covenants and agrees that any mechanic’s lien filed against the Premises for work claimed to have been done for, or materials claimed to have been furnished to, shall be discharged or bonded by Tenant within ten (10) days after the filing thereof, at Tenant’s sole cost and expense.

     18.2. Should Tenant fail to discharge or bond against any lien of the nature described in Section 18.1, Landlord may, at Landlord’s election, pay such claim or post a bond or otherwise provide security to eliminate the lien as a claim against title, and Tenant shall immediately reimburse Landlord for the actual, documented and reasonable costs thereof as Additional Rent.

     18.3. In the event that Tenant leases or finances the acquisition of office equipment, furnishings or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business (which Tenant shall have the right to do), Tenant warrants that any Uniform Commercial Code financing statement executed by Tenant shall, upon its face or by

16

Exhibit thereto, indicate that such financing statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Premises be furnished on a financing statement without qualifying language as to applicability of the lien only to removable personal property located in an identified suite leased by Tenant. Should any holder of a financing statement executed by Tenant record or place of record a financing statement that appears to constitute a lien against any interest of Landlord, Tenant shall, within ten (10) days after filing such financing statement, cause (a) a copy of the lender security agreement or other documents to which the financing statement pertains to be furnished to Landlord to facilitate Landlord’s ability to demonstrate that the lien of such financing statement is not applicable to Landlord’s interest and (b) Tenant’s lender to amend such financing statement and any other documents of record to clarify that any liens imposed thereby are not applicable to any interest of Landlord in the Premises.

19. Indemnification and Exculpation.

     19.1. Subject to Section 19.5 below, Tenant agrees to indemnify, defend and save Landlord harmless from and against any and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages or judgments, and all reasonable expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred in investigating or resisting the same (collectively, “Claims”) arising from injury or death to any person or damage to any property occurring within or about the Premises arising: (a) out of conditions that exist on the Execution Date; or (b) directly or indirectly out of Tenant’s or Tenant’s employees’, agents’ or guests’ use or occupancy of the Premises or a breach or default by Tenant in the performance of any of its obligations hereunder, unless caused solely by Landlord’s willful misconduct or gross negligence.

     19.2. Notwithstanding any provision of Section 19.1 to the contrary, but subject to Section 19.5 below, Landlord shall not be liable to Tenant for, and Tenant assumes all risk of, damage to personal property or scientific research, including, without limitation, loss of records kept by Tenant within the Premises and damage or losses caused by fire, electrical malfunction, gas explosion or water damage of any type (including, without limitation, broken water lines, malfunctioning fire sprinkler systems, roof leaks or stoppages of lines), unless any such loss is due to Landlord’s gross negligence, willful misconduct and/or willful disregard of written notice by Tenant of need for a repair that Landlord is responsible to make for an unreasonable period of time. Tenant further waives any claim for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property as described in this Section 19.2.

     19.3. Landlord shall not be liable for any damages arising from any act, omission or neglect of any third party other than the gross negligence or willful misconduct of any of Landlord’s officers, employees, agents, general partners, members, and Lenders (“Landlord Parties”).

     19.4. Tenant acknowledges that security devices and services, if any, while intended to deter crime, may not in given instances prevent theft or other criminal acts. Landlord shall not be liable for injuries or losses caused by criminal acts of third parties, and Tenant assumes the risk that any security device or service may malfunction or otherwise be circumvented by a criminal. If Tenant desires protection against such criminal acts, then Tenant shall, at Tenant’s sole cost and expense, obtain appropriate insurance coverage. Notwithstanding any contrary provision of this Lease, neither Landlord nor Tenant shall be liable to the other party for any consequential damages, loss of business or profit for a breach or default under this Lease; provided that this sentence shall not limit Landlord’s damages if, as a result of Tenant’s breach of this Lease: (a) Landlord does not or is unable to lease the Premises to another party, or (b) a third party is unable to occupy the Premises on the date specified in such third party’s lease.

     19.5. Tenant shall not be required to indemnify and hold Landlord harmless from any Claim to any person, property or entity resulting from the grossly negligent acts or omissions or willful misconduct of the Landlord Parties in connection with the Landlord Parties’ activities in, on or about the Premises, and Landlord hereby agrees to so indemnify and holds Tenant harmless from any such Claims.

     19.6. The provisions of this Article 19 shall survive the expiration or earlier termination of this Lease.

17

20. Insurance; Waiver of Subrogation.

     20.1. Landlord shall maintain insurance for the Premises in amounts equal to full replacement cost (exclusive of the costs of excavation, foundations and footings, and without reference to depreciation taken by Landlord upon its books or tax returns) or such lesser coverage as Landlord may elect, provided that such coverage shall not be less than ninety percent (90%) of such full replacement cost or the amount of such insurance Landlord’s lender, mortgagee or beneficiary (each, a “Lender”), if any, requires Landlord to maintain, providing protection against any peril generally included within the classification “Fire and Extended Coverage,” together with insurance against sprinkler damage (if applicable), vandalism and malicious mischief. Landlord, subject to availability thereof, shall further insure, if Landlord deems it appropriate, coverage against flood, environmental hazard, earthquake, loss or failure of building equipment, rental loss during the period of repairs or rebuilding, workmen’s compensation insurance and fidelity bonds for employees employed to perform services. Notwithstanding the foregoing, Landlord may, but shall not be deemed required to, provide insurance for any improvements installed by Tenant or that are in addition to the standard improvements customarily furnished by Landlord, without regard to whether or not such are made a part of or are affixed to the Buildings. Any costs incurred by Landlord pursuant to this Section 20.1 shall constitute a portion of Insurance Costs.

     20.2. In addition, Landlord shall carry public liability insurance with a single limit of not less than Ten Million Dollars ($10,000,000) for death or bodily injury, or property damage with respect to the Premises. Any costs incurred by Landlord pursuant to this Section 20.2 shall constitute a portion of Insurance Costs.

     20.3. Tenant shall, at its own cost and expense, procure and maintain in effect, beginning on the Commencement Date or the date of occupancy, whichever occurs first, and continuing throughout the Term (and occupancy by Tenant, if any, after termination of this Lease) comprehensive public liability insurance with limits of not less than Five Million Dollars ($5,000,000) per occurrence for death or bodily injury and not less than Two Million Dollars ($2,000,000) for property damage with respect to the Premises.

     20.4. Tenant shall, at its sole cost and expense, procure and maintain in effect, beginning on the Commencement Date or the date of occupancy, whichever occurs first, and continuing throughout the Term all insurance required to be maintained by the Parcels 1&2 Owner (as defined in the REA) in connection with the Property (as defined in the REA) pursuant to Section 6 of the REA.

     20.5. The insurance required to be purchased and maintained by Tenant pursuant to this Lease shall show, as an additional insured in respect of the Premises, Landlord, BioMed Realty, L.P., BioMed Realty Trust, Inc., Tenant, any management company retained by Landlord to manage the Premises, any ground lessor and any mortgagee of Landlord required to be named pursuant to its mortgage documents. All public liability and property damage policies shall contain a provision that Landlord, although named as an insured, nevertheless shall be entitled to recovery under said policies for any loss occasioned to it, its servants, agents and employees by reason of the negligence of Tenant. Said insurance shall be with companies having a rating of not less than policyholder rating of A and financial category rating of at least Class XII in “Best’s Insurance Guide.” Tenant shall obtain for Landlord from the insurance companies or cause the insurance companies to furnish certificates of coverage to Landlord. No such policy shall be cancelable or subject to reduction of coverage or other modification or cancellation except after thirty (30) days’ prior written notice to Landlord from the insurer. All such policies shall be written as primary policies, not contributing with and not in excess of the coverage that Landlord may carry. Tenant’s policy may be a “blanket policy” that specifically provides that the amount of insurance shall not be prejudiced by other losses covered by the policy. Tenant shall, at least twenty (20) days prior to the expiration of such policies, furnish Landlord with renewals or binders. Tenant agrees that if Tenant does not take out and maintain such insurance, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and at its cost to be paid by Tenant as Additional Rent.

     20.6. Tenant assumes the risk of damage to any fixtures, goods, inventory, merchandise, equipment and leasehold improvements, and Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom, relative to such damage, all as more particularly set forth within this Lease unless caused by Landlord’s gross negligence or willful

18

misconduct. Tenant shall, at Tenant’s sole cost and expense, carry such insurance as Tenant desires for Tenant’s protection with respect to personal property of Tenant or business interruption.

     20.7. In each instance where Tenant’s insurance is to name additional insureds, Tenant shall, upon Landlord’s written request, also designate and furnish certificates evidencing the same to (a) any Lender of Landlord holding a security interest in the Premises or any portion thereof, (b) the landlord under any lease whereunder Landlord is a tenant of the real property upon which the Buildings are located if the interest of Landlord is or shall become that of a tenant under a ground lease rather than that of a fee owner, and (c) any management company retained by Landlord to manage the Premises.

     20.8. Landlord and Tenant each hereby waive any and all rights of recovery against the other or against the officers, directors, employees, agents and representatives of the other on account of loss or damage occasioned by such waiving party or its property or the property of others under such waiving party’s control, in each case to the extent that such loss or damage is insured against under any fire and extended coverage insurance policy that either Landlord or Tenant may have in force at the time of such loss or damage. Such waivers shall continue so long as their respective insurers so permit. Any termination of such a waiver shall be by written notice to the other party, containing a description of the circumstances hereinafter set forth in this Section 20.8. Landlord and Tenant, upon obtaining the policies of insurance required or permitted under this Lease, shall give notice to the insurance carrier or carriers that the foregoing mutual waiver of subrogation is contained in this Lease. If such policies shall not be obtainable with such waiver or shall be so obtainable only at a premium over that chargeable without such waiver, then the party seeking such policy shall notify the other of such conditions, and the party so notified shall have ten (10) days thereafter to either (a) procure such insurance with companies reasonably satisfactory to the other party or (b) agree to pay such additional premium. If the parties do not accomplish either (a) or (b), then this Section 20.8 shall have no effect during such time as such policies shall not be obtainable or the party in whose favor a waiver of subrogation is desired refuses to pay the additional premium. If such policies shall at any time be unobtainable, but shall be subsequently obtainable, then neither party shall be subsequently liable for a failure to obtain such insurance until a reasonable time after notification thereof by the other party. If the release of either Landlord or Tenant, as set forth in the first sentence of this Section 20.8, shall contravene Applicable Laws, then the liability of the party in question shall be deemed not released but shall be secondary to the other party’s insurer.

21. Damage or Destruction.

     21.1. Subject to Section 21.2, In the event of a partial or complete destruction of the Premises by fire or other perils, Landlord shall commence and proceed diligently with the work of repair, reconstruction and restoration of the Premises, and this Lease shall continue in full force and effect.

     21.2. Notwithstanding the terms of this Article 21, Landlord may elect not to rebuild and/or restore the Premises and instead terminate this Lease by notifying Tenant in writing of such termination within sixty (60) days after the date of damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Premises or the Buildings shall be damaged by fire or other casualty or cause or be subject to a condition existing as a result of such a fire or other casualty or cause, and one or more of the following conditions is present: (i) in the reasonable judgment of a contractor selected by Landlord and reasonably approved by Tenant, repairs cannot reasonably be completed within one hundred eighty (180) days of the date of damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Premises or the Buildings, or ground or underlying lessor with respect to the Premises or the Buildings (a) shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt due to an impairment of such holder’s collateral, and the remaining proceeds are insufficient to repair the damage and as a result thereof the deficiency of insurance proceeds exceeds the “Maximum Amount,” as that term is defined below, and Landlord elects not to commence repair to the Premises within one (1) year of such damage or destruction, or (b) shall terminate the ground or underlying lease, as the case may be; (iii) the dollar amount of the damage or condition arising as a result of such damage which is not fully covered by Landlord’s insurance policies (and that would not be fully covered by Landlord’s insurance policies if Landlord had carried the coverage required under this Lease) including any deductible amount, is

19

equal to or greater than Two Hundred and Fifty Thousand Dollars ($250,000) (the “Maximum Amount”), which Maximum Amount shall, as of the date of termination of this Lease, be equal to the product of (a) the Maximum Amount and (b) a fraction, the numerator of which is the number of full months remaining in the Term, or when appropriate the Option Term then applicable, as of the date of the termination of this Lease, and the denominator of which is 180 (or, if applicable, 60 during an Option Term) and Landlord elects not to commence repair to the Premises or Buildings within one (1) year of such damage or destruction; or (iv) the damage occurs during the last twenty-four (24) months of the Term, as such Term may have been extended by Tenant pursuant to this Lease; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs of such damage cannot, in the reasonable opinion of a contractor selected by Landlord and reasonably approved by Tenant, be completed within twelve (12) months after being commenced, Tenant may elect, not later than ten (10) business days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice. At any time, from time to time, after the date occurring thirty (30) days after the date of the damage, but in no event more than once every forty-five (45) days, Tenant may request that Landlord provide Tenant with a certificate from the architect or contractor described above setting forth such architect’s or contractors’ reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within fifteen (15) business days.

     21.3. Landlord shall give written notice to Tenant of its election not to repair, reconstruct or restore the Premises within sixty (60) days following the date of damage or destruction.

     21.4. Upon any termination of this Lease under any of the provisions of this Article 21, the parties shall be released thereby without further obligation to the other from the date possession of the Premises is surrendered to Landlord, except with regard to (a) items occurring prior to the damage or destruction and (b) provisions of this Lease that, by their express terms, survive the expiration or earlier termination hereof.

     21.5. In the event of repair, reconstruction and restoration as provided in this Article 21, all Rent to be paid by Tenant under this Lease shall be abated proportionately based on the extent to which Tenant’s use of the Premises is impaired during the period of such repair, reconstruction or restoration, unless Landlord provides Tenant with other space during the period of repair that, in Tenant’s reasonable discretion, is suitable for the temporary conduct of Tenant’s business; provided, however, that the amount of such abatement shall be reduced by the proceeds of lost rental income insurance actually received by Tenant with respect to the Premises.

     21.6. Notwithstanding anything to the contrary contained in this Article 21, should Landlord be delayed or prevented from completing the repair, reconstruction or restoration of the damage or destruction to the Premises after the occurrence of such damage or destruction by delays resulting from acts of tenants, acts of God; acts of terrorism; adverse weather conditions; war; invasion; insurrection; acts of a public enemy; terrorism; riot; mob violence; civil commotion; sabotage; labor disputes; general shortage of labor, materials, facilities, equipment or supplies on the open market; delay in transportation; delays caused by new, or changes to existing, laws, rules, regulations or orders of any Governmental Authority; moratorium or other governmental action; inability to obtain permits or approvals, including, without limitation, city and public utility approvals beyond the time periods that generally prevail for obtaining such permits and approvals; the acts or inaction of the contractor and subcontractors, if any; or any other cause beyond the reasonable control of Landlord, financial ability excepted, whether similar or dissimilar to the foregoing (collectively, “Force Majeure”), then the time for Landlord to commence or complete repairs shall be extended on a day-for-day basis.

     21.7. If Landlord is obligated to or elects to repair, reconstruct or restore as herein provided, then Landlord shall be obligated to make such repair, reconstruction or restoration only with regard to those portions of the Premises that were originally provided at Landlord’s expense. The repair, reconstruction or restoration of improvements not originally provided by Landlord or at Landlord’s expense shall be the obligation of Tenant. In the event Tenant has elected to upgrade certain improvements, Landlord shall, upon the need for replacement due to an insured loss, construct the improvements to the standard that existed prior to such damage, unless Tenant again elects to upgrade such improvements and pay any incremental costs related thereto, except to the extent that excess insurance proceeds, if received, are adequate to provide such upgrades, in addition to providing for basic repair, reconstruction and restoration of the Premises.

20

     21.8. In addition to its termination right in Section 21.2 above, Tenant shall have the right to terminate this Lease if any damage to the Buildings or Premises: (a) occurs during the last twelve (12) months of the Term of this Lease (including the last twelve (12) months of any Extended Term, if applicable); (b) Tenant is unable to occupy more than twenty-five percent (25%) of the Premises; and (c) in the reasonable judgment of a contractor selected by Landlord and reasonably approved by Tenant, such repairs cannot reasonably be completed within twenty-five percent (25%) of the remaining term of this Lease (including any Extended Term, if applicable).

22. Eminent Domain.

     22.1. Total Taking – Termination. In the event the whole of the Premises, or such part thereof so that reconstruction of the Premises will not result in the Premises being reasonably suitable (as reasonably determined by Landlord and Tenant) for Tenant’s continued occupancy for the uses and purposes permitted by this Lease, shall be taken for any public or quasi-public purpose by any lawful power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to prevent such taking, Tenant or Landlord may terminate this Lease effective as of the date possession is required to be surrendered to said authority.

     22.2. Partial Taking. In the event of a partial taking of the Premises, or of drives, walkways or parking areas serving the Premises for any public or quasi-public purpose by any lawful power or authority by exercise of right of appropriation, condemnation, or eminent domain, or sold to prevent such taking, then, without regard to whether any portion of the Premises occupied by Tenant was so taken, Landlord may elect to terminate this Lease as of such taking if such taking is, in Landlord’s sole opinion, of a material nature such as to make it uneconomical to continue use of the unappropriated portion for purposes of renting office or laboratory space.

     22.3. Tenant shall be entitled to any award that is specifically awarded as compensation for (a) the taking of Tenant’s personal property that was installed at Tenant’s expense and (b) the costs of Tenant moving to a new location. Except as set forth in this Article 22, any award for such taking shall be the property of Landlord.

     22.4. If, upon any taking of the nature described in Sections 22.1 and 22.2, this Lease continues in effect, then (a) Landlord shall promptly proceed to restore the Premises to substantially their same condition prior to such partial taking and this Lease shall, as to the part so taken terminate as of the date that possession of such part of the Premises is taken and the Basic Annual Rent shall be reduced in the same proportion that the floor area of the portion of the Buildings so taken (less any addition thereto by reason of any reconstruction) bears to the original floor area of the Buildings, and (b) in the event of a partial taking of the Diversified Space (as defined in the Parcel 3 Lease), (i) Tenant agrees to sublease to Diversified, at no cost to Diversified, up to 6,600 rentable square feet in the New Parcel 3 Building or in the Buildings in accordance with Diversified’s rights under Article 20 of the Diversified Lease, (ii) Tenant shall be entitled to an abatement of (1) fifty percent (50%) of the Expansion Premises Basic Annual Rent (as defined in the Parcel 3 Lease) for the portion of the Expansion Premises (as defined in the Parcel 3 Lease) (if any) occupied by Diversified, and (2) fifty percent (50%) of the Basic Annual Rent for the portion of the Premises (if any) occupied by Diversified, (iii) Landlord shall pay all costs associated with the relocation of Diversified, including, but not limited to, costs of tenant improvements and moving costs, and (iv) Tenant shall not be entitled to an abatement of any of the operating expenses, including Taxes, Utility Costs, Insurance Costs, and all other utility and insurance costs and expenses in connection with the portion of the Expansion Premises or the Premises occupied by Diversified.

23. Defaults and Remedies.

     23.1. Late payment by Tenant to Landlord of Rent and other sums due shall cause Landlord to incur costs not contemplated by this Lease, the exact amount of which shall be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges that may be imposed on Landlord by the terms of any mortgage or trust deed covering the Premises. Therefore, if any installment of Rent

21

due from Tenant is not received by Landlord within five (5) days after written notice that such payment is due, Tenant shall pay to Landlord an additional sum of three percent (3%) of the overdue Rent as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the costs that Landlord shall incur by reason of late payment by Tenant. Notwithstanding the foregoing, Landlord shall waive the imposition of such late charge for the first late payment of Rent due hereunder in any calendar year of the Term. In addition to the late charge, Rent not paid when due shall bear interest from the fifth (5th) day after the date due until paid at the lesser of (a) twelve percent (12%) per annum or (b) the maximum rate permitted by Applicable Laws.

     23.2. No payment by Tenant or receipt by Landlord of a lesser amount than the Rent payment herein stipulated shall be deemed to be other than on account of the Rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy provided in this Lease or in equity or at law. If a dispute shall arise as to any amount or sum of money to be paid by Tenant to Landlord hereunder, Tenant shall have the right to make payment “under protest,” such payment shall not be regarded as a voluntary payment, and there shall survive the right on the part of Tenant to institute suit for recovery of the payment paid under protest.

     23.3. If Tenant fails to pay any sum of money (other than Basic Annual Rent) required to be paid by it hereunder, or shall fail to perform any other act on its part to be performed hereunder, Landlord may, without waiving or releasing Tenant from any obligations of Tenant, but shall not be obligated to, make such payment or perform such act; provided that (a) such failure by Tenant continues beyond all applicable notice and cure periods after Landlord delivers notice to Tenant demanding performance by Tenant; or (b) such failure by Tenant reasonably could be expected to result in a violation of Applicable Laws, damage to property or injury to any person, or the cancellation of an insurance policy maintained by Landlord. Notwithstanding the foregoing, in the event of an emergency, Landlord shall have the right to enter the Premises and act in accordance with its rights as provided elsewhere in this Lease. Tenant shall pay to Landlord as Additional Rent all sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the annual rate equal to twelve percent (12%) per annum or highest rate permitted by Applicable Laws, whichever is less.

     23.4. The occurrence of any one or more of the following events shall constitute a “Default” hereunder by Tenant:

          23.4.1 The failure by Tenant to make any payment of Rent, as and when due, where such failure shall continue for a period of five (5) days after written notice thereof from Landlord to Tenant;

          23.4.2 The failure by Tenant to observe or perform any obligation or covenant contained herein to be performed by Tenant (other than described in Subsections 23.4.1 and 26.4.2), where such failure shall continue for a period of ten (10) business days after written notice thereof from Landlord to Tenant; provided that, if the nature of Tenant’s default is such that it reasonably requires more than ten (10) business days to cure, Tenant shall not be deemed to be in default if Tenant shall commence such cure within said ten (10) business day period and thereafter diligently prosecute the same to completion;

          23.4.3 Tenant makes an assignment for the benefit of creditors;

          23.4.4 A receiver, trustee or custodian is appointed to or does take title, possession or control of all or substantially all of Tenant’s assets;

          23.4.5 Tenant files a voluntary petition under the United States Bankruptcy Code or any successor statute (the “Bankruptcy Code”) or an order for relief is entered against Tenant pursuant to a voluntary or involuntary proceeding commenced under any chapter of the Bankruptcy Code;

          23.4.6 Any involuntary petition if filed against Tenant under any chapter of the Bankruptcy Code and is not dismissed within sixty (60) days;

22

          23.4.7 Failure to deliver an estoppel certificate in accordance with Article 27;

          23.4.8 The occurrence of a monetary or material non-monetary default under the Parcel 3 Lease;

          23.4.9 The occurrence of any Transfer that is not in compliance with the provisions of Article 24, where such failure shall continue for a period of ten (10) days after written notice thereof from Landlord to Tenant; or

          23.4.10 Tenant’s interest in this Lease is attached, executed upon or otherwise judicially seized and such action is not released within one hundred twenty (120) days of the action.

     No notice given above shall be deemed a forfeiture or a termination of this Lease unless Landlord elects otherwise in such notice.

     23.5. In the event of a Default by Tenant, and at any time thereafter, with or without notice or demand and without limiting Landlord in the exercise of any right or remedy that Landlord may have, Landlord shall be entitled to terminate Tenant’s right to possession of the Premises by any lawful means, in which case this Lease shall terminate and Tenant shall immediately thereafter, surrender possession of the Premises to Landlord. In such event, Landlord shall have the right to re-enter and remove all persons and property, and such property may be removed and stored in a public warehouse or elsewhere at the cost and for the account of Tenant, all without service of notice or resort to legal process and without being deemed guilty of trespass or becoming liable for any loss or damage that may be occasioned thereby. In the event that Landlord shall elect to so terminate this Lease, then Landlord shall be entitled to recover from Tenant all damages incurred by Landlord by reason of Tenant’s default, including, without limitation:

          23.5.1 The worth at the time of award of the unpaid Rent that had been earned at the time of termination; plus

          23.5.2 The worth at the time of award of the amount by which the unpaid Rent that would have been earned during the period commencing with termination of this Lease and ending at the time of award exceeds that portion of the loss of Landlord’s rental income from the Premises that Tenant proves could have been reasonably avoided; plus

          23.5.3 The worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of the loss of Landlord’s rental income from the Premises that Tenant proves could be reasonably avoided; plus

          23.5.4 Any other amount necessary to compensate Landlord for all the detriment caused by Tenant’s failure to perform its obligations under this Lease or that in the ordinary course of things would be likely to result therefrom, including, without limitation, the cost of restoring the Premises to the condition required under the terms of this Lease.

As used in Subsections 23.5.1 and 23.5.2, “worth at the time of award” shall be computed by allowing interest at the rate specified in Section 23.1. As used in Subsection 23.5.3 above, the “worth at the time of the award” shall be computed by taking the present value of such amount, using the discount rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1) percentage point.

     23.6. In addition to any other remedies available to Landlord at law or in equity and under this Lease, Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after Tenant’s Default and abandonment and recover Rent as it becomes due, provided Tenant has the right to sublet or assign, subject only to reasonable limitations). In addition, Landlord shall not be liable in any way whatsoever for its failure or refusal to relet the Premises. For purposes of this Section 23.6, the following acts by Landlord will not constitute the termination of Tenant’s right to possession of the Premises:

          23.6.1 Acts of maintenance or preservation or efforts to relet the Premises, including, but not limited to, alterations, remodeling, redecorating, repairs, replacements and/or painting as Landlord shall consider advisable for the purpose of reletting the Premises or any part thereof, or

23

          23.6.2 The appointment of a receiver upon the initiative of Landlord to protect Landlord’s interest under this Lease or in the Premises.

Notwithstanding the foregoing, in the event of a Default by Tenant, Landlord may elect at any time to terminate this Lease and to recover damages to which Landlord is entitled.

     23.7. In the event Landlord elects to terminate this Lease and relet the Premises, Landlord may execute any new lease in its own name. Tenant hereunder shall have no right or authority whatsoever to collect any Rent from such tenant. The proceeds of any such reletting shall be applied as follows:

          23.7.1 First, to the payment of any indebtedness other than Rent due hereunder from Tenant to Landlord, including, without limitation, storage charges or brokerage commissions owing from Tenant to Landlord as the result of such reletting;

          23.7.2 Second, to the payment of the costs and expenses of reletting the Premises, including (a) alterations and repairs that Landlord deems reasonably necessary and advisable and (b) reasonable attorneys’ fees, charges and disbursements incurred by Landlord in connection with the retaking of the Premises and such reletting;

          23.7.3 Third, to the payment of Rent and other charges due and unpaid hereunder; and

          23.7.4 Fourth, to the payment of future Rent and other damages payable by Tenant under this Lease.

     23.8. All of Landlord’s rights, options and remedies hereunder shall be construed and held to be nonexclusive and cumulative. Landlord shall have the right to pursue any one or all of such remedies, or any other remedy or relief that may be provided by Applicable Laws, whether or not stated in this Lease. No waiver of any default of Tenant hereunder shall be implied from any acceptance by Landlord of any Rent or other payments due hereunder or any omission by Landlord to take any action on account of such default if such default persists or is repeated, and no express waiver shall affect defaults other than as specified in said waiver.

     23.9. Landlord’s termination of (a) this Lease or (b) Tenant’s right to possession of the Premises shall not relieve Tenant of any liability to Landlord that has previously accrued or that shall arise based upon events that occurred prior to the later to occur of (i) the date of Lease termination or (ii) the date Tenant surrenders possession of the Premises.

     23.10. In the event of a Default by Tenant hereunder, to the fullest extent required by Applicable Laws (to the extent such Applicable Laws cannot be modified by contract), Landlord shall use commercially reasonable efforts to mitigate its damages.

     23.11. To the extent permitted by Applicable Laws, Tenant waives any and all rights of redemption granted by or under any present or future Applicable Laws if Tenant is evicted or dispossessed for any cause, or if Landlord obtains possession of the Premises due to Tenant’s default hereunder or otherwise.

     23.12. Landlord shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within a reasonable time, but in no event shall such failure continue for more than thirty (30) days after written notice from Tenant specifying the nature of Landlord’s failure; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. In the event of any default by Landlord (beyond the expiration of all applicable notice and cure periods), Tenant may exercise any rights and remedies available at law or in equity.

     23.13. In the event of any default by Landlord, Tenant shall give notice by registered or certified mail to any (a) beneficiary of a deed of trust or (b) mortgagee under a mortgage covering the Premises or any portion thereof and to any landlord of any lease of land upon or

24

within which the Premises are located, and shall offer such beneficiary, mortgagee or landlord a reasonable opportunity to cure the default, including time to obtain possession of the Premises by power of sale or a judicial action if such should prove necessary to effect a cure; provided that Landlord shall furnish to Tenant in writing, upon written request by Tenant, the names and addresses of all such persons who are to receive such notices; provided, however, in no event shall such reasonable opportunity to cure exceed an additional sixty (60) days within which to cure or correct such default (or if such default cannot be cured or corrected within that time, then such additional time as may be necessary if such mortgagee has commenced within such sixty (60) day period and is diligently pursuing the remedies or steps necessary to cure or correct such default).

24. Assignment or Subletting.

     24.1. Except as hereinafter expressly permitted, Tenant shall not, either voluntarily or by operation of Applicable Laws, directly or indirectly sell, hypothecate, assign, pledge, encumber or otherwise transfer this Lease, or sublet the Premises or any part hereof (each, a “Transfer”), without Landlord’s prior written consent, which consent Landlord may not unreasonably withhold, condition or delay. Tenant shall have the right to Transfer without Landlord’s prior written consent the Premises or any portion thereof to any person or entity that: (a) directly, or indirectly through one or more intermediaries, (i) controls, is controlled by, or is under common control with Tenant, (ii) acquires all or substantially all of the assets of Tenant, or (iii) is the resulting entity of a merger or consolidation of Tenant with another entity; and (b) has a net worth equal to Two Hundred Million Dollars ($200,000,000) (each, a “Tenant’s Affiliate”), provided (1) Tenant shall notify Landlord in writing at least ten (10) days prior to the effectiveness of such Transfer to Tenant’s Affiliate (an “Exempt Transfer”); and (2) Tenant remains obligated under this Lease. For purposes of Exempt Transfers, “control” requires both (y) owning (directly or indirectly) more than fifty-one percent (51%) of the stock or other equity interests of another person and (z) possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person.

     24.2. In the event Tenant desires to effect a Transfer, then, at least twenty (20) business days but not more than one hundred twenty (120) days prior to the date when Tenant desires the assignment or sublease to be effective (the “Transfer Date”), Tenant shall provide written notice to Landlord (the “Transfer Notice”) containing information (including references) concerning the character of the proposed transferee, assignee or sublessee; the Transfer Date; any ownership or commercial relationship between Tenant and the proposed transferee, assignee or sublessee; and the consideration and all other material terms and conditions of the proposed Transfer; and evidence respecting the relevant business experience and financial responsibility and status of the proposed transferee, assignee or sublessee, all in such detail as Landlord shall reasonably require (the “Transfer Information”). Tenant shall also tender to Landlord the actual, documented and reasonable attorneys’ fees and other costs or overhead expenses incurred by Landlord in reviewing Tenant’s request for such Transfer (not to exceed Two Thousand Five Hundred Dollars ($2,500.00) in the aggregate per Transfer request).

     24.3. Landlord, in determining whether consent should be given to a proposed Transfer, may give consideration to (a) the financial strength of such assignee (notwithstanding Tenant remaining liable for Tenant’s performance), and (b) any change in use that such transferee, assignee or sublessee proposes to make in the use of the Premises. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer to a transferee, assignee or sublessee of lacking financial qualifications or seeking a change in the Permitted Use, or jeopardizing directly or indirectly the status of Landlord or any of Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (the “Code”). Notwithstanding anything contained in this Lease to the contrary, (w) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the income or profits derived by the business activities of such occupant, assignee, manager or other transferee; (x) Tenant shall not furnish or render any services to an occupant, assignee, manager or other transferee with respect to whom transfer consideration is required to be paid, or manage or operate the Premises or any capital additions so transferred, with respect to which transfer consideration is being paid; (y) Tenant shall not consummate a Transfer with any person in which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that could cause any portion of the amounts received by Landlord

25

pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or any similar or successor provision thereto or which could cause any other income of Landlord to fail to qualify as income described in Section 856(c)(2) of the Code. Landlord shall respond to Tenant’s proposed Transfer within twenty (20) days after receipt of Tenant’s Transfer request. If Landlord fails to respond within such twenty (20) day period, then Tenant shall provide Landlord with a second written notice stating in bold and all caps 12 point font that “Landlord’s failure to respond to Tenant’s Transfer request within five (5) days after Landlord’s receipt of this second notice shall be deemed approval by Landlord,” and if Landlord does not respond within such five (5) day period, then Landlord shall be deemed to have approved such Transfer request.

     24.4. As conditions precedent to Tenant subleasing the Premises or to Landlord considering a request by Tenant to Tenant’s transfer of rights or sharing of the Premises, Landlord may require any or all of the following:

          24.4.1 Tenant shall remain fully liable under this Lease during the unexpired Term;

          24.4.2 Tenant shall provide Landlord with the Transfer Information;

          24.4.3 If Tenant’s transfer of rights or sharing of the Premises provides for the receipt by, on behalf of or on account of Tenant of any consideration of any kind whatsoever (including, without limitation, a premium rental for a sublease or lump sum payment for an assignment) in excess of the rental and other charges due to Landlord under this Lease, Tenant shall pay fifty percent (50%) of all of such excess to Landlord, after deductions for tenant improvement allowances actually provided by Tenant, alterations (including hard and soft costs), cash and other monetary concessions, marketing expenses, free rent, brokerage commissions and the actual documented and reasonable attorneys fees necessarily incurred in negotiating such sublease or assignment. If said consideration consists of cash paid to Tenant, payment to Landlord shall be made upon receipt by Tenant of such cash payment;

          24.4.4 The proposed transferee, assignee or sublessee shall agree that, in the event Landlord gives such proposed transferee, assignee or sublessee notice that Tenant is in default under this Lease, such proposed transferee, assignee or sublessee shall thereafter make all payments otherwise due Tenant directly to Landlord, which payments shall be received by Landlord without any liability being incurred by Landlord, except to credit such payment against those due by Tenant under this Lease, and any such proposed transferee, assignee or sublessee shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason; provided, however, that in no event shall Landlord or its Lenders, successors or assigns be obligated to accept such attornment;

          24.4.5 Any such consent to Transfer shall be effected on Landlord’s forms, subject to changes by Tenant that are satisfactory to Landlord in its reasonable discretion;

          24.4.6 Tenant shall not then be in default hereunder (beyond the expiration of all applicable notice and cure periods) in any respect;

          24.4.7 Such proposed transferee, assignee or sublessee’s use of the Premises shall not be inconsistent with the Permitted Use;

          24.4.8 Landlord shall not be bound by any provision of any agreement pertaining to the Transfer, except for Landlord’s written consent to the same;

          24.4.9 Tenant shall pay all transfer and other taxes (including interest and penalties) assessed or payable for any Transfer;

          24.4.10 Landlord’s consent (or waiver of its rights) for any Transfer shall not waive Landlord’s right to consent to any later Transfer;

          24.4.11 Tenant shall deliver to Landlord one executed copy of any and all written instruments evidencing the Transfer; and

26

          24.4.12 A list of Hazardous Materials (as defined in Section 36.6 below), certified by the proposed transferee, assignee or sublessee to be true and correct, that the proposed transferee, assignee or sublessee intends to use or store in the Premises. Additionally, Tenant shall deliver to Landlord, on or before the date any proposed transferee, assignee or sublessee takes occupancy of the Premises, all of the items relating to Hazardous Materials of such proposed transferee, assignee or sublessee as described in Section 36.2.

     24.5. Any Transfer that is not in compliance with the provisions of this Article 24 shall be void and constitute a “Default” hereunder.

     24.6. The consent by Landlord to a Transfer shall not relieve Tenant or proposed transferee, assignee or sublessee from obtaining Landlord’s consent to any further Transfer, nor shall it release Tenant or any proposed transferee, assignee or sublessee of Tenant from full and primary liability under this Lease.

     24.7. Notwithstanding any Transfer, Tenant shall remain fully and primarily liable for the payment of all Rent and other sums due or to become due hereunder, and for the full performance of all other terms, conditions and covenants to be kept and performed by Tenant. The acceptance of Rent or any other sum due hereunder, or the acceptance of performance of any other term, covenant or condition thereof, from any person or entity other than Tenant shall not be deemed a waiver of any of the provisions of this Lease or a consent to any Transfer.

     24.8. Licenses to Business Affiliates. Notwithstanding any contrary provision of this Article 24, the original Tenant named hereunder (but not any assignee or subtenant) shall have the right, without the receipt of Landlord’s consent, but on prior written notice to Landlord, to license (but not sublease) up to an aggregate of up to ten percent (10%) of the rentable square feet of the Premises to individuals or entities (each, a “Business Affiliate”), which license to a Business Affiliate shall be on and subject to all of the following conditions: (i) Tenant shall have a direct contractual business relationship (relating to a primary business of Tenant conducted in the Premises and other than Business Affiliate’s use of the Premises) with each such Business Affiliate; (ii) each such Business Affiliate shall be of a character and reputation consistent with the quality of the Buildings; (iii) each such license shall clearly specify that it is only a contract right and that the Business Affiliate is not a subtenant and has no interest in real property; (iv) each such Business Affiliate’s use of the Premises is in a manner consistent with the Permitted Use; (v) no demising walls or separate entrances shall be constructed in the Premises to accommodate any such license; (vi) the term of such license shall not exceed six (6) months; and (vii) the licensee shall pay no rent or other compensation to Tenant in respect of such license. No such license shall relieve Tenant from any liability under this Lease.

     24.9. If Tenant sublets the Premises or any portion thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and appoints Landlord as assignee and attorney-in-fact for Tenant, and Landlord (or a receiver for Tenant appointed on Landlord’s application) may collect such rent and apply it toward Tenant’s obligations under this Lease; provided that, until the occurrence of a Default (beyond the expiration at all applicable notice and cure periods) by Tenant, Tenant shall have the right to collect such rent.

25. Attorneys’ Fees. If either party commences an action against the other party arising out of or in connection with this Lease, then the substantially prevailing party shall be entitled to have and recover from the other party reasonable attorneys’ fees, charges and disbursements and costs of suit.

26. Definition of Landlord. With regard to obligations imposed upon Landlord pursuant to this Lease, the term “Landlord,” as used in this Lease, shall refer only to Landlord or Landlord’s then-current successor-in-interest. In the event of any transfer, assignment or conveyance of Landlord’s interest in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, Landlord herein named (and in case of any subsequent transfers or conveyances, the subsequent Landlord) shall be automatically freed and relieved, from and after the date of such transfer, assignment or conveyance, from all liability for the performance of any covenants or obligations contained in this Lease thereafter to be performed by Landlord and, without further agreement, the transferee, assignee or conveyee of Landlord’s in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, shall be deemed to have assumed and agreed to observe and perform any and all covenants and obligations of Landlord

27

hereunder during the tenure of its interest in this Lease or the Property. Landlord or any subsequent Landlord may transfer its interest in the Premises or this Lease without Tenant’s consent.

27. Estoppel Certificate. Tenant shall, within fifteen (15) days of receipt of written notice from Landlord, execute, acknowledge and deliver a statement in writing substantially in the form attached to this Lease as Exhibit C, or on any other commercially reasonable form reasonably requested by a proposed Lender or purchaser, (a) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in advance, if any, (b) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (c) setting forth such further information with respect to this Lease or the Premises as may be reasonably requested thereon. Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of which the Premises are a part. Tenant’s failure to deliver such statement within such the prescribed time shall, at Landlord’s option, constitute a Default under this Lease, and, in any event, shall be binding upon Tenant that this Lease is in full force and effect and without modification except as may be represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution and that all other statements set forth in such certificate are true and correct. Landlord shall, within fifteen (15) days of receipt of written notice from Tenant but in no event more than once every twelve (12) months, provide to Tenant an estoppel certificate signed by Landlord, (a) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in advance, if any, and (b) acknowledging that there are not, to Landlord’s knowledge, any uncured defaults on the part of Tenant hereunder, or specifying such defaults if any are claimed.

28. Joint and Several Obligations. If more than one person or entity executes this Lease as Tenant, then:

     28.1. Each of them is jointly and severally liable for the keeping, observing and performing of all of the terms, covenants, conditions, provisions and agreements of this Lease to be kept, observed or performed by Tenant; and

     28.2. The term “Tenant” as used in this Lease shall mean and include each of them, jointly and severally. The act of, notice from, notice to, refund to, or signature of any one or more of them with respect to the tenancy under this Lease, including, without limitation, any renewal, extension, expiration, termination or modification of this Lease, shall be binding upon each and all of the persons executing this Lease as Tenant with the same force and effect as if each and all of them had so acted, so given or received such notice or refund, or so signed.

29. Limitation of Landlord’s Liability.

     29.1. If Landlord is in default under this Lease and, as a consequence, Tenant recovers a monetary judgment against Landlord, the judgment shall be satisfied only out of (a) the proceeds of sale received on execution of the judgment and levy against the right, title and interest of Landlord in the Premises, (b) rent or other income from such real property receivable by Landlord, (c) the consideration received by Landlord from the sale, financing, refinancing or other disposition of all or any part of Landlord’s right, title or interest in the Premises and (d) any casualty insurance proceeds which Landlord receives for damage to the Premises.

     29.2. Landlord shall not be personally liable for any deficiency under this Lease. If Landlord is a partnership or joint venture, then the partners of such partnership shall not be personally liable for Landlord’s obligations under this Lease, and no partner of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any partner of Landlord except as may be necessary to secure jurisdiction of the partnership or joint venture. If Landlord is a corporation, then the shareholders, directors, officers, employees and agents of such corporation shall not be personally liable for

28

Landlord’s obligations under this Lease, and no shareholder, director, officer, employee or agent of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any shareholder, director, officer, employee or agent of Landlord. If Landlord is a limited liability company, then the members of such limited liability company shall not be personally liable for Landlord’s obligations under this Lease, and no member of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any member of Landlord except as may be necessary to secure jurisdiction of the limited liability company. No partner, shareholder, director, employee, member or agent of Landlord shall be required to answer or otherwise plead to any service of process, and no judgment shall be taken or writ of execution levied against any partner, shareholder, director, employee or agent of Landlord.

     29.3. If Tenant is a partnership or joint venture, then the partners of such partnership shall not be personally liable for Tenant’s obligations under this Lease, and no partner of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any partner of Tenant except as may be necessary to secure jurisdiction of the partnership or joint venture. If Tenant is a corporation, then the shareholders, directors, officers, employees and agents of such corporation shall not be personally liable for Tenant’s obligations under this Lease, and no shareholder, director, officer, employee or agent of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any shareholder, director, officer, employee or agent of Tenant. If Tenant is a limited liability company, then the members of such limited liability company shall not be personally liable for Tenant’s obligations under this Lease, and no member of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any member of Tenant except as may be necessary to secure jurisdiction of the limited liability company. No partner, shareholder, director, employee, member or agent of Tenant shall be required to answer or otherwise plead to any service of process, and no judgment shall be taken or writ of execution levied against any partner, shareholder, director, employee or agent of Tenant. Notwithstanding the foregoing, in no event shall the provisions of this Section 29.3 relieve Tenant’s partners, shareholders, directors, employees, members or agents of any personal liability arising out of, or in connection with, such partner’s, shareholder’s, director’s, employee’s, member’s or agent’s gross negligence or willful misconduct.

     29.4. Each of the covenants and agreements of this Article 29 shall be applicable to any covenant or agreement either expressly contained in this Lease or imposed by Applicable Laws and shall survive the expiration or earlier termination of this Lease.

30. Premises Control by Landlord. Landlord and Landlord’s Agents may, at any and all reasonable times during non-business hours (or during business hours if Tenant so requests), and upon twenty-four (24) hours’ prior notice (provided that no time restrictions shall apply or advance notice be required if an emergency necessitates immediate entry), enter the Premises to (a) inspect the same and to determine whether Tenant is in compliance with its obligations hereunder, (b) supply any service Landlord is required to provide hereunder, (c) show the Premises to prospective purchasers or tenants during the final year of the Term, (d) post notices of nonresponsibility, (e) access the telephone equipment, electrical substation and fire risers, or (f) alter, improve or repair any portion of the Buildings. In connection with any such alteration, improvement or repair as described in Subsection 30(f) above, Landlord and Landlord’s Agents may erect in the Premises scaffolding and other structures reasonably required for the alteration, improvement or repair work to be performed. Subject to Section 15.4 above, in no event shall Tenant’s Rent abate as a result of Landlord’s activities pursuant to this Section 30; provided, however, that all such activities shall be conducted in such a manner so as to cause as little interference to Tenant as is reasonably possible. Landlord shall at all times retain a key with which to unlock all of the doors in the Premises. If an emergency (where there is an imminent threat to persons or property) necessitates immediate access to the Premises, Landlord may use whatever force is necessary to enter the Premises, and any such entry to the Premises shall not constitute a forcible or unlawful entry to the Premises, a detainer of the Premises, or an eviction of Tenant from the Premises or any portion thereof.

31. Construction; Quiet Enjoyment.

     31.1. Temporary Construction Easement. Tenant hereby grants Landlord and the Landlord Parties from the Execution Date through the completion of the construction of the Landlord’s Construction Work and the Tenant Improvements (each as defined in the New Parcel 3 Lease): (a) access through the portion of Premises that are improved with walkways and driveways for the purpose of access, and (b) over and across the portion of the Premises that is shown on Exhibit G for storage of building supplies, materials and equipment, and staging of construction, for any and all purposes reasonably related to the construction of the New Parcel 3 Building.

29

     31.2. So long as Tenant is not in default under this Lease or as otherwise permitted by this Lease, Landlord or anyone acting through or under Landlord shall not disturb Tenant’s occupancy of the Premises. Notwithstanding the foregoing, to the extent that Landlord uses commercially reasonable efforts to minimize any interference the construction of the New Parcel 3 Building may have on Tenant’s use and quiet enjoyment of the Premises for Tenant’s normal business operations, Tenant hereby (a) accepts any and all inconveniences associated with the construction of the New Parcel 3 Building, including, any noise, paint, fumes, dust, debris, obstruction of access (including any obstruction caused by the erection of scaffolding, barricades or other necessary structures on the Property), or any other inconvenience caused by the construction of the New Parcel 3 Building, (b) agrees that the performance of the construction of the New Parcel 3 Building shall not constitute a constructive eviction nor shall Tenant be entitled to an abatement of Rent, and (c) acknowledges and agrees that Landlord shall not, for any reason, be responsible or liable to Tenant for any direct or indirect injury to Tenant or Tenant’s Agents, or interference with Tenant’s business, arising from the construction of the New Parcel 3 Building; provided, however, that if Landlord fails to use its commercially reasonable efforts to minimize any interference that the construction of the New Parcel 3 Building may have on Tenant’s use of the Premises for Tenant’s normal business operations, such failure results in an Adverse Condition, and as a direct result of such Adverse Condition, Tenant is unable to conduct its business in a reasonable manner in a material portion of the Premises, Tenant shall be entitled to an abatement of rent with respect to such Adverse Condition to the extent Tenant is entitled to an abatement of rent pursuant to the terms and conditions of Section 15.4 above.

32. Subordination and Attornment.

     32.1. Subject to the delivery of the non-disturbance agreements described in this Article 32 as a condition precedent to any such subordination, this Lease shall be subject and subordinate to the lien of any mortgage, deed of trust, or lease in which Landlord is tenant now or hereafter in force against the Premises or any portion thereof and to all advances made or hereafter to be made upon the security thereof without the necessity of the execution and delivery of any further instruments on the part of Tenant to effectuate such subordination. In consideration of, and as a condition precedent to, Tenant’s agreement to permit its interest pursuant to this Lease to be subordinated to any particular future ground or underlying lease of the Buildings or the Premises or to the lien of any mortgage or trust deed, hereafter enforced against the Buildings or the Premises and to any renewals, extensions, modifications, consolidations and replacements thereof, Landlord shall deliver to Tenant a non-disturbance agreement on (a) the form of Exhibit E attached hereto, (b) a commercially reasonable form of non-disturbance agreements of the lessor under such ground lease or underlying lease or the holder of such mortgage or trust deed, or (c) another commercially reasonable form. Landlord’s delivery to Tenant of non-disturbance agreement(s) in favor of Tenant from any ground lessors, mortgage holders or lien holders of Landlord who later came into existence at any time prior to the expiration of the Term shall be in consideration of, and a condition precedent to, Tenant’s agreement to be bound by the terms of this Article 32. Tenant shall be entitled, at Tenant’s sole cost and expense, to record any such non-disturbance agreement promptly after full execution and delivery of such agreement.

     32.2. Notwithstanding the foregoing, Tenant shall execute and deliver upon demand such further commercially reasonable instrument or instruments evidencing such subordination of this Lease to the lien of any such mortgage or mortgages or deeds of trust or lease in which Landlord is tenant as may be required by Landlord. However, if any such mortgagee, beneficiary or Landlord under lease wherein Landlord is tenant so elects, this Lease shall be deemed prior in lien to any such lease, mortgage, or deed of trust upon or including the Premises regardless of date and Tenant shall execute a statement in writing to such effect at Landlord’s request.

     32.3. Upon written request of Landlord and opportunity for Tenant to review, Tenant agrees to execute any Lease amendments not materially altering the terms of this Lease, if required by a mortgagee or beneficiary of a deed of trust encumbering real property of which the Premises constitute a part incident to the financing of the real property of which the Premises constitute a part. Any change affecting the amount or timing of the consideration to be paid by Tenant or modifying the term of this Lease shall be deemed as materially altering the terms hereof.

30

     32.4. Subject to Section 32.1, in the event any proceedings are brought for foreclosure, or in the event of the exercise of the power of sale under any mortgage or deed of trust made by Landlord covering the Premises, Tenant shall at the election of the purchaser at such foreclosure or sale attorn to the purchaser upon any such foreclosure or sale and recognize such purchaser as Landlord under this Lease.

33. Surrender.

     33.1. No surrender of possession of any part of the Premises shall release Tenant from any of its obligations hereunder, unless such surrender is accepted in writing by Landlord.

     33.2. The voluntary or other surrender of this Lease by Tenant shall not effect a merger with Landlord’s fee title or leasehold interest in the Premises or any portion thereof, unless Landlord consents in writing, and shall, at Landlord’s option, operate as an assignment to Landlord of any or all subleases.

     33.3. The voluntary or other surrender of any ground or other underlying lease that now exists or may hereafter be executed affecting the Premises or any portion thereof, or a mutual cancellation thereof or of Landlord’s interest therein by Landlord and its lessor shall not effect a merger with Landlord’s fee title or leasehold interest in the Premises and shall, at the option of the successor to Landlord’s interest in the Premises or any portion thereof operate as an assignment of this Lease.

     33.4. In the event Tenant has performed any Alterations in accordance with this Lease, upon surrender of the Premises, Tenant shall reimburse Landlord for any extra costs and expenses incurred by Landlord by reason of any delays in re-leasing the Premises caused by Tenant’s removal of such Alterations.

34. Waiver and Modification No provision of this Lease may be modified, amended or supplemented except by an agreement in writing signed by Landlord and Tenant. The waiver by Landlord of any breach by Tenant of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition herein contained. The waiver by Tenant of any breach by Landlord of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition herein contained.

35. Waiver of Jury Trial and Counterclaims. To the extent allowed under Applicable Laws, the parties waive trial by jury in any action, proceeding or counterclaim brought by the other party hereto related to matters arising out of or in any way connected with this Lease; the relationship between Landlord and Tenant; Tenant’s use or occupancy of the Premises; or any claim of injury or damage related to this Lease or the Premises.

36. Hazardous Materials.

     36.1. After the Execution Date, Tenant shall not cause or permit any Hazardous Materials (as hereinafter defined) to be brought upon, kept or used in or about the Premises in violation of Applicable Laws by Tenant or Tenant’s Agents. If Tenant breaches such obligation, or if the presence of Hazardous Materials brought upon, kept or used in or about the Premises by Tenant or Tenant’s Agents results in contamination of the Premises or any adjacent property, or if contamination of the Premises or any adjacent property by Hazardous Materials otherwise occurs before or during the term of this Lease or any extension or renewal hereof or holding over hereunder (other than in connection with substances that migrated to the Premises from any adjoining property, except in the event Tenant is aware of such contamination and neither remedies such contamination nor promptly notifies Landlord of the existence of such contamination), then Tenant shall indemnify, save, defend and hold Landlord, its agents and contractors harmless from and against any and all claims, judgments, damages, penalties, fines, costs, liabilities and losses (including, without limitation, diminution in value of the Premises or any portion thereof; damages for the loss or restriction on use of rentable or usable space or of any amenity of the Premises; damages arising from any adverse impact on marketing of space in the Premises; and sums paid in settlement of claims, attorneys’ fees, consultants’ fees and experts’ fees) that arise before, during or after the Term as a result of such breach or contamination, except to the extent arising solely out of Landlord’s construction of the Landlord’s Construction Work or the Tenant Improvements (each as defined in the Parcel 3

31

Lease); provided, however, in no event shall Tenant’s indemnity extend to consequential damages; provided that this sentence shall not limit Landlord’s damages if, as a result of Tenant’s breach of this Lease: (a) Landlord does not or is unable to lease the Premises to another party, or (b) a third party is unable to occupy the Premises on the date specified in such third party’s lease. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or restoration work required by any Governmental Authority because of Hazardous Materials present in the air, soil or groundwater above, on or under the Premises. Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about the Premises or any adjacent property caused or permitted by Tenant or Tenant’s Agents results in any contamination of the Premises or any adjacent property, then Tenant shall promptly take all actions at its sole cost and expense as are necessary to return the Premises and any adjacent property to their respective condition existing prior to the time of such contamination; provided that Landlord’s written approval of such action shall first be obtained, which approval Landlord shall not unreasonably withhold; and provided, further, that it shall be reasonable for Landlord to withhold its consent if such actions could have a material adverse long-term or short-term effect on the Premises.

     36.2. Landlord acknowledges that it is not the intent of this Article 36 to prohibit Tenant from operating its business as described in Section 2.7 above. Tenant may operate its business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored according to Applicable Laws. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Execution Date a list identifying each type of Hazardous Material to be present on the Premises and setting forth any and all governmental approvals or permits required in connection with the presence of such Hazardous Material on the Premises (the “Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List on or prior to each annual anniversary of the Execution Date and shall also deliver an updated Hazardous Materials List before any new Hazardous Materials are brought onto the Premises. Tenant shall deliver to Landlord true and correct copies of the following documents (hereinafter referred to as the “Documents”) relating to the handling, storage, disposal and emission of Hazardous Materials prior to Execution Date or, if unavailable at that time, concurrent with the receipt from or submission to any Governmental Authority: permits; approvals; reports and correspondence; storage and management plans; notices of violations of Applicable Laws; plans relating to the installation of any storage tanks to be installed in or under the Premises (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion); and all closure plans or any other documents required by any and all Governmental Authorities for any storage tanks installed in, on or under the Premises for the closure of any such storage tanks. Tenant shall not be required, however, to provide Landlord with any portion of the Documents containing information of a proprietary nature that, in and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous Materials.

     36.3. At any time, and from time to time, prior to the expiration of the Term, Landlord shall have the right to conduct appropriate tests of the Premises to demonstrate that Hazardous Materials are present or that contamination has occurred due to Tenant or Tenant’s agents, employees or invitees. Tenant shall pay all reasonable costs of such tests of the Premises if such tests demonstrate that Tenant has breached any provision of this Lease regarding Hazardous Materials or has any clean-up obligations under this Article 36.

     36.4. If underground or other storage tanks storing Hazardous Materials are: (a) located on the Premises; (b) hereafter placed on the Premises by Tenant or Tenant’s Agents, (c) hereafter used by Tenant or Tenant’s Agents, or (d) placed on the Premises by any other party and Tenant is aware that such party placed such underground or other storage tank on the Premises, Tenant shall monitor the storage tanks, maintain appropriate records, implement reporting procedures, properly close any underground storage tanks, and take or cause to be taken all other steps necessary or required under the Applicable Laws. Tenant shall pay all reasonable costs of such tests of the Premises

     36.5. Tenant’s and Landlord’s obligations under this Article 36 shall survive the expiration or earlier termination of this Lease. During any period of time needed by Tenant or Landlord after the termination of this Lease to complete the removal from the Premises of any

32

such Hazardous Materials that Tenant is liable for pursuant to the terms and conditions of this Lease, Tenant shall continue to pay Rent in accordance with this Lease, which Rent shall be prorated daily.

     36.6. As used herein, the term “Hazardous Material” means any hazardous or toxic substance, material or waste that is or becomes regulated by any Governmental Authority.

37. Miscellaneous.

If the conditions set forth in this Section 37.1 are not satisfied or waived on or before April 10, 2007, this Lease shall become null and void

     37.2.

Landlord shall not be required to furnish any services or facilities or to make any repairs, replacements or alterations of any kind in or on the Premises except as specifically provided herein. Tenant shall receive all invoices and bills relative to the Premises and, except as otherwise provided herein, shall pay for all expenses directly to the person or company submitting a bill without first having to forward payment for the expenses to Landlord. Tenant shall at Tenant’s sole cost and expense be responsible for the management of the Premises, shall maintain the landscaping and parking lot, and shall make those additional repairs and alterations required of Tenant hereunder to maintain the Premises in first class condition.

     37.4. Where applicable in this Lease, the singular includes the plural and the masculine or neuter includes the masculine, feminine and neuter. The Section headings of this Lease are not a part of this Lease and shall have no effect upon the construction or interpretation of any part hereof.

     37.5. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease or otherwise until execution by and delivery to both Landlord and Tenant.

     37.6. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor.

     37.7. Each provision of this Lease performable by Tenant shall be deemed both a covenant and a condition.

     37.8. Whenever consent or approval of either party is required, that party shall not unreasonably withhold such consent or approval, except as may be expressly set forth to the contrary.

33

     37.9. The terms of this Lease are intended by the parties as a final expression of their agreement with respect to the terms as are included herein, and may not be contradicted by evidence of any prior or contemporaneous agreement.

     37.10. Any provision of this Lease that shall prove to be invalid, void or illegal shall in no way affect, impair or invalidate any other provision hereof, and all other provisions of this Lease shall remain in full force and effect and shall be interpreted as if the invalid, void or illegal provision did not exist.

     37.11. Landlord may, but shall not be obligated to, record a short form memorandum hereof without Tenant’s consent. Tenant shall reasonably cooperate with Landlord in such recording. Neither party shall record this Lease. Tenant shall have the right to record a memorandum of this Lease (which Landlord shall execute); provided, however, that Tenant shall be responsible for the cost of recording any memorandum of this Lease, including any transfer or other taxes incurred in connection with said recordation. Landlord shall reasonably cooperate with Tenant in such recording at Tenant’s sole cost and expense.

     37.12. The language in all parts of this Lease shall be in all cases construed as a whole according to its fair meaning and not strictly for or against either Landlord or Tenant.

Any notices given pursuant to this Lease shall be addressed to Tenant at the Premises, or to Landlord or Tenant at the addresses shown in Sections 2.9 and 2.10, respectively. Either party may, by notice to the other given pursuant to this Section, specify additional or different addresses for notice purposes.

     37.15. This Lease shall be governed by, construed and enforced in accordance with the laws of the State in which the Premises are located, without regard to such State’s conflict of law principles.

     37.17.

Tenant shall, within ninety (90) days after the end of Tenant’s financial year, furnish Landlord with a certified copy of Tenant’s audited year-end financial statements for the previous year. Tenant represents and warrants that all financial statements, records and information furnished by Tenant to Landlord in connection with this Lease are true, correct and complete in all respects. Notwithstanding the foregoing, the provisions of this Section 37.17 shall not apply to Tenant so long as Tenant is a publicly traded company that is listed on a United States stock exchange.

     37.18. This Lease is subject to any recorded covenants, conditions or restrictions now or hereinafter affecting the Premises or Property (the “CC&Rs”). Tenant shall comply with all CC&Rs except to the extent any future CC&Rs (a) materially adversely affects Tenant’s use of the Premises for its Permitted Use; or (b) materially increase Tenant’s costs under this Lease.

34

38. Option to Extend Term. Tenant shall have the option (“Option”) to extend the Term of this Lease as to the entire Premises (and no less than the entire Premises) upon the following terms and conditions. Any extension of the Term pursuant to any Option shall be on all the same terms and conditions as this Lease, except as follows:

     38.1. Tenant shall have three (3) options to extend the Term of this Lease by five (5) years each (each, an “Extended Term”), upon the same terms and conditions as this Lease (except as provided below). Basic Annual Rent shall be adjusted on the first (1st) day of each Extended Term and every twenty-four (24) months thereafter in accordance with Article 6. The Basic Annual Rent during each Extended Term shall equal the greater of: (a) the Fair Market Value for the Extended Term; and (b) 102.5% of the then-current Basic Annual Rent at the end of the then-current Term or Extended Term, as applicable. “Fair Market Value” means the then-prevailing average annual rate that comparable landlords have accepted in current transactions from new, non-equity (i.e., not being offered equity in the Buildings), nonrenewal, nonexpansion and nonaffiliated tenants of similar financial strength for comparable space in comparable class “A” office buildings comparably located, with comparable size, quality and floor height in a first class office building, or as appropriate, a laboratory building, taking into consideration all relevant factors, including, without limitation, the proposed lease term, the tenant inducements, allowances or concessions, if any, and excluding specialized tenant improvements or tenant paid improvements for a comparable term, with the determination of Fair Market Value to take into account all relevant factors, including tenant inducements, allowances or concessions, if any, the extent of the services provided or to be provided to the Premises, and contraction and expansion options. In the event the tenant inducements, allowances or concessions granted differ from the terms contained in this Lease, an adjustment to the Fair Market Value shall be made on a basis consistent with the adjustments commonly made in the market for comparable differences and concession packages. If Landlord and Tenant cannot agree on the Fair Market Value for purposes of any Extended Term then they shall engage a mutually agreeable independent third party appraiser, which appraiser shall be a real estate broker with at least ten (10) years’ experience in appraising the rental value of leased commercial premises (for research and development and laboratory uses) in the San Diego, California area (the “Appraiser”). If the parties cannot agree on the Appraiser, each shall within ten (10) days after such impasse appoint an Appraiser (meeting the qualifications set forth above) and, within ten (10) days after the appointment of both such Appraisers, those two Appraisers shall select a third Appraiser meeting the qualifications set forth above. If either party fails to timely appoint an Appraiser, then the Appraiser the other party appoints shall be the sole Appraiser. Within ten (10) days after appointment of all Appraiser(s), Landlord and Tenant shall each simultaneously give the Appraisers (with a copy to the other party) its determination of Fair Market Value, with such supporting data or information as each submitting party determines appropriate. Within ten (10) days after such submissions, the Appraisers shall by majority vote select either Landlord’s or Tenant’s Fair Market Value. The Appraisers may not select or designate any other Fair Market Value. The determination of the Appraiser(s) shall bind the parties

     38.2. The Option is not assignable separate and apart from this Lease.

     38.3. The Option is conditional upon Tenant giving Landlord written notice of its election to exercise an Option at least twelve (12) months prior to the end of the expiration of the initial term of this Lease and, if exercised, the applicable Extended Term. Time shall be of the essence as to Tenant’s exercise of each Option. Tenant assumes full responsibility for maintaining a record of the deadlines to exercise any Option(s). Tenant acknowledges that it would be inequitable to require Landlord to accept any exercise of any Option(s) after the date provided for in this Section.

     38.4. Notwithstanding anything contained in this Article 38, Tenant shall not have the right to exercise an Option:

          38.4.1 During the time commencing from the date Landlord delivers to Tenant a written notice that Tenant is in monetary or material non-monetary default under any provision of this Lease or the Parcel 3 Lease and continuing until Tenant has cured the specified default; or

          38.4.2 At any time after any Default as described in Article 23 of this Lease (provided, however, that, for purposes of this Subsection 38.4.2, Landlord shall not be required to provide Tenant with notice of such Default) and continuing until Tenant cures any such Default, if such Default is susceptible to being cured; or

35

          38.4.3 In the event that Tenant has defaulted in the performance of its obligations under this Lease three (3) or more times and a service or late charge has become payable under Section 23.1 for each of such defaults during the twelve (12)-month period immediately prior to the date that Tenant intends to exercise an Option, whether or not Tenant has cured such defaults.

     38.5. The period of time within which Tenant may exercise an Option shall not be extended or enlarged by reason of Tenant’s inability to exercise such Option because of the provisions of Section 38.4.

39. Tenant’s Authority. Tenant hereby covenants and warrants that (a) Tenant is duly incorporated or otherwise established or formed and validly existing under the laws of its state of incorporation, establishment or formation, (b) Tenant has and is duly qualified to do business in the state in which the Property is located, (c) Tenant has full corporate, partnership, trust, association or other appropriate power and authority to enter into this Lease and to perform all Tenant’s obligations hereunder and (d) each person (and all of the persons if more than one signs) signing this Lease on behalf of Tenant is duly and validly authorized to do so.

40. Landlord’s Authority. Landlord hereby covenants and warrants that (a) Landlord is duly incorporated or otherwise established or formed and validly existing under the laws of its state of incorporation, establishment or formation, (b) Landlord has and is duly qualified to do business in the state in which the Property is located, (c) Landlord has full corporate, partnership, trust, association or other appropriate power and authority to enter into this Lease and to perform all Landlord’s obligations hereunder and (d) each person (and all of the persons if more than one signs) signing this Lease on behalf of Landlord is duly and validly authorized to do so.

41. Confidentiality. Neither party shall disclose any terms or conditions of this Lease (including Rent) or give a copy of this Lease to any third party, and Landlord shall not release to any third party any nonpublic financial information or nonpublic information about Tenant’s ownership structure that Tenant gives Landlord, except (a) if required by Applicable Laws or in any judicial proceeding, provided that the releasing party has given the other party reasonable notice of such requirement, if feasible, (b) to a party’s attorneys, accountants, brokers and other bona fide consultants or advisers, provided such third parties agree to be bound by this Section or (c) to bona fide prospective assignees or subtenants of this Lease, provided they agree in writing to be bound by this Section.

42. Excavation. If any excavation shall be made upon land adjacent to or under the Buildings, or shall be authorized to be made, Tenant shall afford to the person causing or authorized to cause such excavation, license to enter the Premises for the purpose of performing such work as said person shall deem necessary or desirable to preserve and protect the Buildings from injury or damage and to support the same by proper foundations, without any claim for damages or liability against Landlord and without, subject to the terms and conditions of this Lease, reducing or otherwise affecting Tenant’s obligations under this Lease.

43. Telecommunications Equipment. At any time during the Term, subject to the terms of this Article 43 and subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld or delayed, Tenant shall have the exclusive right to install, at Tenant’s sole cost and expense, satellite or microwave dishes or other communication equipment (the “Telecommunications Equipment”) upon the roof of the Buildings. The physical appearance and the size of the Telecommunications Equipment shall be subject to Landlord’s written approval prior to installation, which approval will not unreasonably be withheld, any covenants, conditions, or restrictions encumbering the Premises and, any Applicable Laws. Tenant shall maintain such Telecommunications Equipment in good condition and repair, at Tenant’s sole cost and expense. The cost of the Telecommunications Equipment, including but not limited to the permitting, installation, maintenance and removal thereof shall be at Tenant’s sole cost and expense. If Tenant fails to maintain its Telecommunications Equipment, or if Tenant fails to remove such Telecommunications Equipment upon termination of this Lease, or fails to repair any damage caused by such removal, Landlord may do so at Tenant’s expense. Tenant shall on demand reimburse Landlord for all costs incurred by Landlord to effect such removal, which amounts shall be deemed Additional Rent and shall include without limitation, all sums disbursed, incurred or deposited by Landlord, including Landlord’s costs, expenses and actual attorneys’ fees with interest thereon. Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including

36

reasonable attorneys’ fees and disbursements) arising directly or indirectly out of Tenant’s failure to perform any of its obligations under this Article 43.

44. Access to Premises. Subject to Section 30, Tenant shall be granted access to the Premises (including the parking facilities) twenty-four (24) hours per day, seven (7) days per week, every day of the year.

45. Secured Areas. Notwithstanding anything to the contrary set forth in this Lease, Tenant may designate certain areas of the Premises as “Secured Areas” should Tenant require such areas for the purpose of securing certain valuable property or confidential information. Landlord may not enter such Secured Areas except in the case of emergency or in the event of a Landlord inspection, in which case Landlord shall provide Tenant with one (1) business day prior written notice of the specific date and time of such Landlord inspection.

     We establish in favor of Beneficiary our irrevocable and unconditional Letter of Credit numbered as identified above (the “L/C”) for an aggregate amount of $___, expiring at ___:00 p.m. on ___ or, if such day is not a Banking Day, then the next succeeding Banking Day (such date, as extended from time to time, the “Expiry Date”). “Banking Day” means a weekday except a weekday when commercial banks in ___ are authorized or required to close.

     We authorize Beneficiary to draw on us (the “Issuer”) for the account of ___(the “Account Party”), under the terms and conditions of this L/C.

     Funds under this L/C are available by presenting the following documentation (the “Drawing Documentation”): (a) the original L/C and (b) a sight draft substantially in the form of Exhibit A, with blanks filled in and bracketed items provided as appropriate. No other evidence of authority, certificate, or documentation is required.

     Drawing Documentation must be presented at Issuer’s office at ___ on or before the Expiry Date by personal presentation, courier or messenger service, or fax. Presentation by fax shall be effective upon electronic confirmation of transmission as evidenced by a printed report from the sender’s fax machine. After any fax presentation, but not as a condition to its effectiveness, Beneficiary shall with reasonable promptness deliver the original Drawing Documentation by any other means. Issuer will on request issue a receipt for Drawing Documentation.

     We agree, irrevocably, and irrespective of any claim by any other person, to honor drafts drawn under and in conformity with this L/C, within the maximum amount of this L/C, presented to us on or before the Expiry Date, provided we also receive (on or before the Expiry Date) any other Drawing Documentation this L/C requires.

     We shall pay this L/C only from our own funds by check or wire transfer, in compliance with the Drawing Documentation.

     If Beneficiary presents proper Drawing Documentation to us on or before the Expiry Date, then we shall pay under this L/C at or before the following time (the “Payment Deadline”): (a) if presentment is made at or before noon of any Banking Day, then the close of such Banking Day; and (b) otherwise, the close of the next Banking Day. We waive any right to delay payment beyond the Payment Deadline. If we determine that Drawing Documentation is not proper, then we shall so advise Beneficiary in writing, specifying all grounds for our determination, within one Banking Day after the Payment Deadline.

     Partial drawings are permitted. This L/C shall, except to the extent reduced thereby, survive any partial drawings.

     We shall have no duty or right to inquire into the validity of or basis for any draw under this L/C or any Drawing Documentation. We waive any defense based on fraud or any claim of fraud.

EXHIBIT D-1

     The Expiry Date shall automatically be extended by one year (but never beyond ___ the “Outside Date”) unless, on or before the date thirty (30) days before any Expiry Date, we have given Beneficiary notice that the Expiry Date shall not be so extended (a “Nonrenewal Notice”). We shall promptly upon request confirm any extension of the Expiry Date under the preceding sentence by issuing an amendment to this L/C, but such an amendment is not required for the extension to be effective. We need not give any notice of the Outside Date.

     Beneficiary may from time to time without charge transfer this L/C, in whole but not in part, to any transferee (the “Transferee”). Issuer shall look solely to Beneficiary for payment of any fee for any transfer of this L/C. Beneficiary or Transferee shall consummate such transfer by delivering to Issuer the original of this L/C and a Transfer Notice substantially in the form of Exhibit B, purportedly signed by Beneficiary, and designating Transferee. Issuer shall promptly reissue or amend this L/C in favor of Transferee as Beneficiary. Upon any transfer, all references to Beneficiary shall automatically refer to Transferee, who may then exercise all rights of Beneficiary. Issuer expressly consents to any transfers made from time to time in compliance with this paragraph.

     Any notice to Beneficiary shall be in writing and delivered by hand with receipt acknowledged or by overnight delivery service such as FedEx (with proof of delivery) at the above address, or such other address as Beneficiary may specify by written notice to Issuer. A copy of any such notice shall also be delivered, as a condition to the effectiveness of such notice, to: ___ (or such replacement as Beneficiary designates from time to time by written notice).

     No amendment that adversely affects Beneficiary shall be effective without Beneficiary’s written consent.

FORM OF SUBORDINATION, NON-DISTURBANCE
AND ATTORNMENT AGREEMENT

RECORDED AT REQUEST OF
AND WHEN RECORDED RETURN TO:

Attention:

SUBORDINATION, NONDISTURBANCE, AND ATTORNMENT AGREEMENT

     This Subordination, Nondisturbance, and Attornment Agreement (“Agreement”) is made as of ___, ___ between                      (“Lender”), a                     , having its principal place of business at                     ,                     ,                      and Illumina, Inc. (“Tenant”), a Delaware corporation, having its principal place of business at 9855 through 9885 Towne Centre Drive, San Diego, California.

Recitals:

     A. Lender has agreed to make a loan to BMR-9865 Towne Center Drive LLC, a Delaware limited liability company (“Landlord”), to be secured by a deed of trust, dated                     , ___, and recorded on                     , ___, as Instrument No.                     , in the Official Records of San Diego County, California (together with all amendments, increases, renewals, modifications, consolidations, spreaders, combinations, supplements, replacements, substitutions, and extensions, either current or future, referred to hereafter as the “Mortgage”) encumbering Landlord’s ownership interest in real property located in San Diego County, State of California. The legal description of the encumbered real property (the “Mortgage Premises”) is set forth in Exhibit A, attached to this Agreement. The Mortgage, together with the promissory note or notes, the loan agreement(s), and other documents executed in connection with it are hereafter collectively referred to as the “Loan Documents”.

     B. On                     , ___, Tenant and Landlord entered into that certain Lease for a portion of the Mortgage Premises (the “Lease”). The Lease creates a leasehold estate in favor of Tenant for space (the “Leased Premises”) located on the Mortgage Premises.

     C. In connection with execution of the Mortgage, Landlord also executed and delivered to Lender an [Assignment of Leases, Rents and Profits] dated                     , ___, and recorded on                     , ___, as Instrument No.                    , in the Official Records of the County Recorder of San Diego, California concerning all rents, issues and profits from the Mortgage Premises. This document, together with all amendments, renewals, modifications consolidations, replacements, substitutions and extensions, is hereafter referred to as the “Assignment of Rents.”

     TO CONFIRM their understanding concerning the legal effect of the Mortgage and the Lease, in consideration of the mutual covenants and agreements contained in this Agreement and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Lender and Tenant, intending to be legally bound, agree and covenant as follows:

     1. Representations and Warranties. Tenant warrants and represents that the Lease is in full force and effect and that, as of the date of this Agreement and to Tenant’s actual knowledge, there is no default under the Lease by Landlord or Tenant.

     2. Tenant Subordination.

          2.1 Subject to the provisions of Section 3, the Loan Documents shall constitute a lien or charge on the Mortgage Premises that is prior and superior to the Lease, to the leasehold estate created by it, and to all rights and privileges of Tenant under it; by this

EXHIBIT E-1

Agreement, the Lease, the leasehold estate created by it, together with all rights and privileges of Tenant under it, is, subject to Section 3, subordinated, at all times, to the lien or charge of the Loan Documents in favor of Lender.

          2.2 By executing this Agreement, Tenant, subject to Section 3, subordinates the Lease and Tenant’s interest under it to the lien right and security title, and terms of the Loan Documents, and to all advances or payments made, or to be made, under any Loan Document.

     3. Nondisturbance.

          3.1 Lender consents to the Lease.

          3.2 Despite Tenant’s subordination under Section 2, Tenant’s peaceful and quiet possession of the Leased Premises shall not be disturbed and Tenant’s rights and privileges under the Lease, shall not be diminished by Lender’s exercise of its rights or remedies under the Loan Documents (subject to the provisions of Section 5), provided that:

     (a) no Default (as defined in the Lease) exists; and

     (b) the Lease has not been canceled or terminated (without regard to whether Landlord or Tenant is then in default under the Lease).

          3.3 Tenant shall not be named or joined in any foreclosure, trustee’s sale, or other proceeding to enforce the Loan Documents unless such joinder shall be legally required to perfect the foreclosure, trustee’s sale, or other proceeding.

     4. Attornment.

          4.1 If Lender shall succeed to Landlord’s interest in the Mortgage Premises by foreclosure of the Mortgage, by deed in lieu of foreclosure, or in any other manner, Tenant shall be bound to Lender (and Lender shall be bound to Tenant) under all the terms, covenants and conditions of the Lease for the balance of its term with the same force and effect as if Lender were the Landlord under the Lease. Tenant shall be deemed to have full and complete attornment to, and to have established direct privity between Tenant and:

     (a) Lender when in possession of the Mortgage Premises;

     (b) a receiver appointed in any action or proceeding to foreclose the Mortgage;

     (c) any party acquiring title to the Mortgage Premises; or

     (d) any successor to Landlord.

          4.2 Tenant’s attornment is self-operating, and it shall continue to be effective without execution of any further instrument by any of the parties to this Agreement or the Lease. Lender agrees to give Tenant written notice if Lender has succeeded to the interest of the Landlord under the Lease. Subject to Section 5, the terms of the Lease are incorporated into this Agreement by reference.

          4.3 If the interests of Landlord under the Lease are transferred by foreclosure of the Mortgage, deed in lieu of foreclosure, or otherwise, to a party other than Lender (“Transferee”), in consideration of, and as condition precedent to, Tenant’s agreement to attorn to any such Transferee, Transferee shall be deemed to have assumed all terms, covenants, and conditions of the Lease to be observed or performed by Landlord from the date on which the Transferee succeeds to Landlord’s interests under the Lease; provided that the liability of any Transferee to Tenant under the terms of the Lease shall be limited in the same manner as Lender’s liability is limited under Section 5.

     5. Lender as Landlord. If Lender shall succeed to the interest of Landlord under the Lease, Lender shall be bound to Tenant under all the terms, covenants and conditions of the Lease, and Tenant shall, from the date of Lender’s succession to the Landlord’s interest under the Lease, have the same remedies against Lender for breach of the Lease that Tenant would have had under the Lease against Landlord; provided, however, that despite anything to the contrary in this Agreement or the Lease, Lender, as successor to the Landlord’s interest, shall not be:

EXHIBIT E-2

     (a) liable for any act or omission of any previous landlord (including Landlord), provided that the foregoing shall not be construed to limit Tenant’s right to possession of the Leased Premises for the entire term of the Lease, as extended, on the terms and conditions of the Lease;

     (b) subject to any offsets or defenses which Tenant might have had against any previous landlord (including Landlord) relating to any event or occurrence before the date of attornment. The foregoing shall not limit either (a) Tenant’s right to exercise against successor landlord any offset right otherwise available to Tenant because of events occurring after the date of attornment, or (b) successor landlord’s obligation to correct any conditions that existed as of the date of attornment and that violate successor landlord’s obligations as landlord under the Lease;

     (c) unless actually received by Lender, bound by any rent or additional rent that Tenant might have paid for more than one month in advance to any prior landlord (including Landlord), other than, and only to the extent of, prepayments (if any) expressly required under the Lease; or

     (d) bound by an amendment or modification of the Lease which would materially adversely affect any right of Landlord under the Lease made without Lender’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed, except for any amendment or modification evidencing Tenant’s exercise of any rights expressly granted to Tenant in the Lease so long as such amendment or modification reflects the terms and conditions provided with regards to such rights as reflected in the Lease. Notwithstanding the foregoing, any modification, amendment or waiver made or entered into between Landlord and Tenant shall be binding as between Landlord and Tenant.

     6. Notice of Default; Right To Cure. Tenant agrees to give Lender prompt written notice of any known default by Landlord under the Lease. Tenant agrees that, before Tenant exercises any of its rights or remedies under the Lease, Lender shall have the right, but not the obligation, to cure the default within the same time given Landlord in the lease to cure the default, plus an additional thirty (30) days. Tenant agrees that the cure period shall be extended by the time reasonably necessary for Lender to commence foreclosure proceedings and to obtain possession of the Mortgage Premises, provided that this sentence shall not apply if the breach or default by Landlord poses an immediate threat to the health, safety or welfare of Tenant’s employees, customers or invitees at the Leased Premises, provided further that:

     (a) Lender shall notify Tenant of Lender’s intent to effect its remedy within thirty (30) days after receipt of Tenant’s notice;

     (b) Lender initiates immediate steps to foreclose on or to recover possession of the Mortgage Premises;

     (c) Lender initiates legal proceedings to appoint a receiver for the Mortgage Premises or to foreclose on or recover possession of the Mortgage Premises within the thirty (30) day period; and

     (d) Lender prosecutes such proceedings and remedies with due diligence and continuity to completion.

     Tenant also agrees to its use its commercially reasonable efforts to give Lender notice of any casualty damage to the Mortgage Premises, but Tenant’s failure to provide such notice shall not be a default under this Agreement.

     7. Assignment of Rents. If Landlord defaults in its performance of the terms of the Loan Documents, Tenant agrees to recognize the Assignment of Rents made by Landlord to Lender and shall pay to Lender, as assignee, from the time Lender gives Tenant written notice that Landlord is in default under the terms of the Loan Documents, the rents under the Lease, but only those rents that are due or that become due under the terms of the Lease after notice by

EXHIBIT E-3

Lender. Payments of rents to Lender by Tenant under the assignment of rents and Landlord’s default shall continue until the first of the following occurs:

     (a) No further rent is due or payable under the Lease;

     (b) Lender gives Tenant written notice that the Landlord’s default under the Loan Documents has been cured and instructs Tenant that the rents shall thereafter be payable to Landlord; or

     (c) The lien of the Mortgage has been foreclosed and the purchaser at the foreclosure sale (whether Lender or a Transferee) gives Tenant written notice of the foreclosure sale. On giving written notice, the purchaser shall succeed to Landlord’s interests under the Lease, after which time the rents and other benefits due Landlord under the Lease shall be payable to the purchaser as the owner of the Mortgage Premises.

     8. Tenant’s Reliance. When complying with the provisions of Section 7, Tenant shall be entitled to rely on the notices given by Lender under Section 7, and Landlord agrees to release, relieve, protect and indemnify Tenant from and against any and all loss, claim, damage, or liability (including reasonable attorney’s fees) arising out of Tenant’s compliance with such notice.

     Tenant shall be entitled to full credit under the Lease for any rents paid to Lender in accordance with Section 7 to the same extent as if such rents were paid directly to Landlord. Any dispute between Lender (or Lender’s Transferee) and Landlord as to the existence of a default by Landlord under the terms of the Mortgage, the extent or nature of such default, or Lender’s right to foreclosure of the Mortgage, shall be dealt with and adjusted solely between Lender (or Transferee) and Landlord, and Tenant shall not be made a party to any such dispute (unless required by law).

     9. Lender’s Status. Nothing in this Agreement shall be construed to be an agreement by Lender to perform any covenant of the Landlord under the Lease unless and until it obtains title to the Mortgage Premises by power of sale, judicial foreclosure, or deed in lieu of foreclosure, or obtains possession of the Mortgage Premises under the terms of the Loan Documents.

     10. Cancellation of Lease. Tenant agrees that it will not cancel, terminate, or surrender the Lease, except at the normal expiration of the Lease term or as provided in the Lease, or except as otherwise provided in Section 5 above, enter into any agreement, amendment, or modification of the Lease except any agreement, amendment, or modification contemplated by or provided by the terms of the Lease unless Lender gives its prior written consent, which shall not be unreasonably withheld, conditioned or delayed; provided, however, that no Lender consent shall be required pursuant to a termination permitted under the Lease.

     11. Special Covenants. Despite anything in this Agreement or the Lease to the contrary, if Lender acquires title to the Mortgage Premises, Tenant agrees that: Lender shall have the right at any time in connection with the sale or other transfer of the Mortgage Premises to assign the Lease or Lender’s rights under it to any person or entity, and that Lender, its officers, directors, shareholders, agents, and employees shall be released from any further liability under the Lease arising after the date of such transfer, provided that the assignee of Lender’s interest assumes Lender’s obligations under the Lease (including liability for all obligations accruing prior to the date of the assignment), in writing, from the date of such transfer.

     12. Transferee’s Liability. If a Transferee acquires title to the Mortgage Premises:

     (a) Tenant’s recourse against Transferee for default under the Lease shall be limited to the Mortgage Premises or any sale, insurance, or condemnation proceeds from the Mortgage Premises;

     (b) Tenant shall look exclusively to Transferee’s interests described in (a) above for the payment and discharge of any obligations imposed on Transferee under this Agreement or the Lease ; and

     (c) Transferee, its officers, directors, shareholders, agents, and employees are released and relieved of any personal liability under the Lease; and

EXHIBIT E-4

     (d) Tenant shall not collect or attempt to collect any judgment out of any other assets, or from any general or limited partners or shareholders of Transferee.

     Notwithstanding the foregoing, Tenant reserves all rights and remedies available to it in law or in equity against the prior landlord.

     13. Transferee’s Performance Obligations. Subject to the limitations provided in Sections 11 and 12, if a Transferee acquires title to the Mortgage Premises, the Transferee shall perform and recognize: all tenant improvement allowance provisions, all rent-free and rent rebate provisions, and all options and rights of offer, in addition to Landlord’s other obligations under the Lease.

     14. Notice. All notices required by this Agreement shall be given in writing and shall be deemed to have been duly given for all purposes when:

     (a) deposited in the United States mail (by registered or certified mail, return receipt requested, postage prepaid); or

     (b) deposited with a nationally recognized overnight delivery service such as Federal Express or Airborne.

          (i) A Mortgagee shall have the absolute right, but no duty or obligation, to cure or correct a breach of this Agreement by the Owner whose property is secured by the Mortgagee’s Mortgage within any applicable cure period provided for such breach by such mortgagor Owner plus an additional period of twenty (20) days after notice to the Mortgagee of expiration of the cure period allowed the mortgagor Owner before the other Owner may exercise any right or remedy to which it may be entitled as a Benefitted Party, except exercise of a self-help right in an emergency situation.

          (ii) Should any prospective Mortgagee require a modification or modifications of this Agreement, which modification or modifications will not cause an increased cost or expense to the Owner whose property is not subject to the Mortgage of such Mortgagee or in any other way materially and adversely change the rights and obligations of such Owner, then and in such event, such Owner agrees that this Agreement may be so modified and agrees to execute whatever documents are reasonably required therefor and deliver the same to the other Owner within ten (10) business days following written requests therefor by the other Owner or prospective Mortgagee.

          11.12 Attorney’s Fees. In the event any legal action, proceeding or arbitration is commenced to interpret or enforce the terms of, or obligations arising out of, this Agreement, or to recover damages for the breach hereof, the party prevailing in any such action, proceeding or arbitration shall be entitled to recover from the non-prevailing party all reasonable attorney’s fees, costs and expenses incurred by the prevailing party.

On or before June 1, 2007, Landlord shall, at Landlord’s sole cost and expense, cause Landlord’s contractor, Reno Contracting or such replacement thereof as Landlord may make from time to time with Tenant’s approval, which approval shall not be unreasonably withheld or delayed (“Contractor”), to commence and thereafter diligently prosecute the construction of the shell and core of the Expansion Building to completion pursuant to the Approved CW Plans (as defined in the Work Letter), subject only to CW Permitted Changes (as defined in the Work Letter), (all such construction, collectively, “Landlord’s Construction Work”). Landlord’s Construction Work shall be performed in a workmanlike manner, and in compliance with all Applicable Laws. The commencement and completion of Landlord’s Construction Work shall be subject to delays resulting from acts of Tenants, acts of God; acts of terrorism; adverse weather conditions; war; invasion; insurrection; acts of a public enemy; terrorism; riot; mob violence; civil commotion; sabotage; labor disputes; general shortage of labor, materials, facilities, equipment or supplies on the open market; delay in transportation; delays caused by new, or changes to existing, laws, rules, regulations or orders of any Governmental Authority; moratorium or other governmental action; inability to obtain permits or approvals, including, without limitation, city and public utility approvals beyond the time periods that generally prevail for obtaining such permits and approvals; the acts or inaction of the contractor and subcontractors, if any; or any other cause beyond the reasonable control of Landlord, financial ability excepted, whether similar or dissimilar to the foregoing (collectively, “Force Majeure”).

4

          4.1.2 Completion of Construction. Landlord’s Construction Work shall be deemed “Substantially Complete” or there shall be “Substantial Completion” if Landlord has (a) completed all of Landlord’s Construction Work identified on the Approved CW Plans (subject only to such incomplete or defective work as will not materially or adversely impact Tenant’s continuous and uninterrupted use of the Expansion Premises for its Permitted Use (collectively, the “Punchlist Items”)) and (b) received a temporary or permanent certificate of occupancy from the applicable municipal authority(ies) and a certificate of substantial completion from the architect.

          4.1.3 Warranties. Landlord shall use commercially reasonable efforts (but without any obligation to commence or pursue any litigation) to cause Contractor to complete with reasonable promptness the Punchlist Items and repair with reasonable promptness all defects in the construction of Landlord’s Construction Work in accordance with the Approved CW Plans as to which Tenant notifies Landlord in writing (which notice Tenant shall give within thirty (30) days following the Phase 1 Commencement Date). Notwithstanding the foregoing, Landlord shall cause all Punchlist Items that reasonably can be completed within thirty (30) days after Substantial Completion of the Landlord’s Construction Work to be completed within thirty (30) days after Substantial Completion of the Landlord’s Construction Work. Except for such Punchlist Items and except for latent defects and non-compliance of Landlord’s Construction Work with Applicable Laws, Tenant shall, subject to the terms hereof, be deemed to have accepted the Expansion Premises in the condition delivered to it “As Is,” provided, however, except as to those items that Landlord is required to correct pursuant to this Section, Landlord shall partially assign to Tenant (but without prejudice to any of Landlord’s rights of enforcement) all warranties that it has received under the construction contract, any subcontract, or from any material supplier. Notwithstanding the foregoing, if Tenant notifies Landlord within the period beginning on Substantial Completion of the Landlord’s Construction Work and continuing through the date that is twelve (12) months thereafter (the “CW Warranty Period”), of (a) latent defects in the construction of the Landlord’s Construction Work; or (b) non-compliance of Landlord’s Construction Work with Applicable Laws, then as Landlord’s sole and exclusive obligation with respect thereto, Landlord shall cause such latent defect or non-compliance promptly to be remedied. All warranty claims shall be barred and shall lapse unless such claim is made in writing to Landlord, with a description of the claim made, on or before the expiration of the CW Warranty Period.

     4.2. Tenant Improvements.

          4.2.1 Tenant Improvements. Landlord shall cause the Contractor to commence and thereafter diligently prosecute the construction of the tenant improvements in the Expansion Building pursuant to the Work Letter (the “Tenant Improvements”). The Tenant Improvements shall be performed in a workmanlike manner and in compliance with all Applicable Laws and substantially in compliance with the Approved TI Plans (as defined in the Work Letter), subject to minor deviations that do not alter the type, scope and quality of the Tenant Improvements depicted on the Approved TI Plans. The portion of the TI Costs for which Landlord is responsible (the “TI Allowance”) shall not exceed (subject to the terms hereof) the TI Allowance Amount (as defined below). “TI Costs” means all Tenant Delay Costs (as defined below) and costs of the Tenant Improvements (the “TI Costs”), including the costs of (i) construction, (ii) construction management by Landlord (which costs shall be stipulated to equal one and one-half percent (1.5%) of the cost of the Tenant Improvements, including the Excess Cost (as defined below)) (the “Construction Management Fee”), (iii) space planning, architect, engineering and other related services, (iv) costs and expenses for labor, material, equipment and fixtures, and (v) building permits and other taxes, fees, charges and levies by governmental and quasi-governmental agencies for permits or for inspections of the Tenant Improvements. Notwithstanding the foregoing, in no event shall the TI Allowance be used for: (w) the purchase of any furniture, personal property or other non-building system equipment, (x) the cost of work that is not authorized by the Approved TI Plans (subject to any TI Change) or otherwise approved in writing by Landlord, (y) costs resulting from any default by Tenant of its obligations under this Lease, or (z) costs that are recoverable or reasonably recoverable by Tenant from a third party (e.g., insurers, warrantors or tortfeasors). The “TI Allowance Amount” shall be Forty-Seven and 15/100 Dollars ($47.15) per rentable square foot of the Expansion Building, plus the amount of any Additional Allowance that Tenant elects to use to pay the cost of the Tenant Improvements.

5

          4.2.2 In the event the estimated total TI Costs (the “Estimated TI Costs”) exceeds the TI Allowance Amount, Tenant shall pay such overage, as reasonably estimated by Landlord from time to time (the “Excess Cost”), as the work progresses as follows: on or before the tenth (10^th) day of each month, Landlord shall deliver to Tenant an application for reimbursement, accompanied by reasonable documentary evidence of the construction costs of such Tenant Improvements incurred since the last application for reimbursement. On or before the tenth (10^th) day following delivery of such application for reimbursement, Tenant shall pay to Landlord an amount that (when added to any prior reimbursements of Excess Costs by Tenant) will equal (a) a fraction, the numerator of which is the amount of TI Costs incurred prior to the date of the application for reimbursement, and the denominator of which is the Estimated TI Costs, times (b) the Excess Cost (the “Tenant Reimbursement”). In the event the TI Allowance and the estimated Excess Cost are not sufficient to cover the actual TI Costs, including all approved change orders, Landlord shall adjust the Excess Cost accordingly.

          4.2.3 Architects and Consultants. The architect, engineering consultants, design team, general contractor and subcontractors responsible for the construction of the Tenant Improvements shall be selected pursuant to the procedures set forth in the Work Letter. Subject to the terms of the Work Letter, Tenant hereby approves of Ferguson Pape Baldwin Architects as Landlord’s architect and Reno Contracting as Landlord’s general contractor.

          4.2.4 Completion of Tenant Improvements. The Tenant Improvements shall be deemed “Substantially Complete” or there shall be “Substantial Completion” if (i) Landlord has completed, in compliance with all Applicable Laws, all of the Tenant Improvements identified on and substantially in accordance with the Approved TI Plans (subject only to the Punchlist Items and minor deviations that do not alter the type, scope and quality of the Tenant Improvements depicted on the Approved TI Plans) and Tenant is provided with continuous and uninterrupted use of the applicable portion of the Expansion Premises and the Expansion Building for Tenant’s Permitted Use (including Tenant’s parking), except to the extent reasonably necessary for Landlord’s Contractor to complete the Punchlist Items in accordance with Section 4.1.2, and (ii) Landlord has obtained a certificate of occupancy or temporary certificate of occupancy (or its equivalent) allowing Tenant to legally occupy the Expansion Premises.

          4.2.5 Warranties. Landlord shall use commercially reasonable efforts (but without obligation to commence or pursue any litigation) to cause Contractor to complete with reasonable promptness the Punchlist Items and repair with reasonable promptness all defects in the construction of the Tenant Improvements in accordance with the Work Letter as to which Tenant notifies Landlord in writing (which notice Tenant shall give within thirty (30) days following the Phase 1 Commencement Date). Notwithstanding the foregoing, Landlord shall cause all Punchlist Items that reasonably can be completed within sixty (60) days after Substantial Completion of the Tenant Improvements to be completed within sixty (60) days after Substantial Completion of the Tenant Improvements. Except for such Punchlist Items and except for latent defects and non-compliance of Tenant Improvements with Applicable Laws, Tenant shall, subject to the terms hereof, be deemed to have accepted the Expansion Premises in the condition delivered to it “As Is,” provided, however, except as to those items that Landlord is required to correct pursuant to this Section, Landlord shall partially assign to Tenant (but without prejudice to any of Landlord’s rights of enforcement) all warranties that it has received under the construction contract, any subcontract, or from any material supplier. Notwithstanding the foregoing, if Tenant notifies Landlord within the period beginning on Substantial Completion of the Tenant Improvements and continuing through the date that is twelve (12) months thereafter (the “TI Warranty Period”), of (a) latent defects in the construction of the Tenant Improvements; or (b) non-compliance of Tenant Improvements with Applicable Laws, then as Landlord’s sole and exclusive obligation with respect thereto, Landlord shall cause such latent defects or non-compliance promptly to be remedied. All warranty claims shall be barred and shall lapse unless such claim is made in writing to Landlord, with a description of the claim made, on or before the expiration of the TI Warranty Period.

     4.3. Additional Allowance. Landlord shall, at Tenant’s request, provide an additional tenant improvement allowance not to exceed Thirty-Five Dollars ($35.00) per rentable square foot of the Expansion Premises (the “Additional Allowance”), which amount may be used by Tenant to increase the scope of Landlord’s Construction Work or the Tenant Improvements pursuant to the terms and conditions contained in the Work Letter and/or pay for any other costs payable by Tenant pursuant to the Work Letter. In the event Tenant elects to use all or any

6

portion of the Additional Allowance, Tenant shall pay to Landlord, as Rent, an amount equal to the Additional Allowance disbursed by Landlord, together with interest thereon at the rate of nine percent (9%) per annum. Tenant shall make payments in respect of the Additional Allowance plus interest thereon in equal monthly installments so that the full amount shall be paid on or before the expiration of the initial Term. Tenant shall pay such amounts with the payment of Basic Annual Rent for each month. If Tenant has not paid the full amount of the Additional Allowance plus interest thereon at the expiration or earlier termination of this Lease, then upon the expiration or termination of this Lease, Tenant shall, within thirty (30) days thereafter, pay the unpaid portion of such amount to Landlord. The payments Tenant is requested to make in respect of the Additional Allowance shall constitute “Additional Rent.”

5. Possession and Commencement Date.

     5.1. Tenant’s Access. So long as Tenant does not (in Landlord’s reasonable judgment) unreasonably or unnecessarily interfere with Landlord’s Construction Work or the Tenant Improvements, upon reasonable prior written notice to Landlord, Tenant may enter upon any Phase prior to the respective Commencement Date for the purpose of, among other things, installing improvements (including cabling) or the placement of personal property; provided, however, that Tenant shall furnish to Landlord evidence satisfactory to Landlord that insurance coverages required of Tenant under the provisions of Article 23 are in effect, and such entry shall be subject to all the terms and conditions of this Lease other than the payment of Rent. Tenant shall reimburse Landlord for all actual documented incremental costs that result from such entry and indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising out of any entry and/or activities upon the Expansion Premises by Tenant or Tenant’s Agents.

     5.2. Possession and Commencement Date.

          5.2.1 Diversified Building Premises. Tenant hereby acknowledges that immediately prior to the Diversified Building Premises Commencement Date, Tenant occupied the Diversified Building Premises and that Tenant is in possession of the Diversified Building Premises, and is familiar with the condition thereof and accepts the Diversified Building Premises in its “as is” condition with all faults, and Landlord makes no representation or warranty of any kind with respect the Diversified Building Premises, and Landlord will have no obligation to improve, alter or repair the Diversified Building Premises, except as specifically set forth herein. Tenant acknowledges that Tenant was the prior owner of the Diversified Building and as such is fully aware of the current conditions of the Diversified Building.

          5.2.2 Phase 1 Premises.

               (a) Landlord shall endeavor to tender possession of the Phase 1 Premises to Tenant on or before the Phase 1 Estimated Delivery Date. If Landlord’s Construction Work or the Tenant Improvements as required pursuant to the terms of the Work Letter are not Substantially Complete on or before the Phase 1 Estimated Delivery Date for any reason whatsoever, then, except as provided below, this Lease shall not be void or voidable, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom and the Phase 1 Commencement Date shall not occur until Substantial Completion of Landlord’s Construction Work and the Tenant Improvements occurs; provided, however, if the satisfaction of the requirements for Substantial Completion of Landlord’s Construction Work or the Tenant Improvements have been actually delayed by any Tenant Delay, then, subject to the terms hereof, Substantial Completion of Landlord’s Construction Work and the Tenant Improvements shall be deemed to occur when (as reasonably determined by Landlord) Substantial Completion of Landlord’s Construction Work and the Tenant Improvements would have occurred if such Tenant Delay had not occurred. Within thirty (30) days after Substantial Completion of Landlord’s Construction Work and the Tenant Improvements, Landlord’s architect shall calculate and certify in writing to Landlord and Tenant the Rentable Area of the Phase 1 Premises in accordance with Article 9. “Tenant Delay” shall mean: (1) delays or failure of Tenant or Tenant’s architect to deliver items in accordance with the Work Letter attached hereto as Exhibit J; (2) Tenant’s failure to timely fulfill its obligations as set forth in the Work Letter within the time periods set forth therein; (3) delays caused by CW Tenant Change Order Requests (as defined in the Work Letter) or TI Tenant Change Order Requests (as defined in the Work Letter); 4) unavailability of materials, components or finishes for the Tenant Improvements that have an unusually long lead-time for delivery; (5) a willful or negligent act or

7

omission of Tenant, Tenant’s Agents that interferes with the progress of the work, (6) any delay that results from Tenant’s use of an architect other than Ferguson Pape Baldwin Architects for purposes of the TI Program and the Schematic TI Plans, or (7) any other event or circumstance described as a Tenant Delay in the Work Letter. Landlord shall not assess any day towards a Tenant Delay for delays caused solely by Landlord’s contractors, Landlord or any third parties or due to Force Majeure. Notwithstanding anything above to the contrary, (i) the first ten (10) days of Tenant Delays (if any) associated with any CW Tenant Change Order Request or TI Tenant Change Order Request shall not be deemed a Tenant Delay, (ii) no delay shall be considered a Tenant Delay unless Landlord provides Tenant written notice of such Tenant Delay, to the extent Landlord and/or management personnel of Landlord’s contractor(s) are aware of such Tenant Delay, and Tenant fails to cure such delay within one (1) business day; provided that no such notice and cure period shall be required if such delay is with respect to interference with the Landlord’s construction activities and Landlord has previously notified Tenant of similar Tenant Delays, (iii) no delay shall be considered a Tenant Delay in the event Substantial Completion of Landlord’s Construction Work and the Tenant Improvements occurs on or before the Phase 1 Estimated Delivery Date. Landlord and Contractor shall take commercially reasonable actions, remedial or otherwise, to complete the Landlord’s Construction Work and the Tenant Improvements by the Phase 1 Estimated Delivery Date notwithstanding any Tenant Delay. All additional cost and expense payable by Landlord, if any, to complete the Landlord’s Construction Work or the Tenant Improvements due to Tenant Delay (“Tenant Delay Costs”), shall constitute TI Costs, and to the extent the TI Costs exceed the TI Allowance Amount, Tenant shall pay such actual and documented additional costs and expenses as “Excess Costs” in accordance with Section 4.2.2 of this Lease.

               (b) Landlord and Tenant shall each execute and deliver to the other a factually correct written acknowledgment of the actual Phase 1 Commencement Date and the Expiration Date when such is established in the form of Exhibit F, and shall attach it to this Lease as Exhibit F-1. Failure to execute and deliver such acknowledgement, however, shall not affect the Phase 1 Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain validation by any medical review board or other similar governmental licensing of the Expansion Premises required for the Permitted Use by Tenant shall not serve to extend the Phase 1 Commencement Date.

          5.2.3 Phase 2 Premises.

               (a) In the event Tenant elects to occupy the Phase 2 Premises before the Phase 2 Estimated Delivery Date, then Tenant shall deliver to Landlord at least five (5) business days before the date Tenant elects to occupy the Phase 2 Premises a written notice setting forth the date Tenant intends to occupy the Phase 2 Premises (collectively, the “Phase 2 Commencement Date Notice”).

               (b) Landlord shall tender possession of the Phase 2 Premises to Tenant upon the Phase 2 Commencement Date. On the Phase 2 Commencement Date, Landlord and Tenant shall each execute and deliver to the other a factually correct written acknowledgement of the actual Phase 2 Commencement Date and the Expiration Date when established, in the form Exhibit F, and shall attach it to this Lease as Exhibit F-2. Failure to execute and deliver such acknowledgement, however, shall not affect the Phase 2 Commencement Date or Tenant’s liability hereunder.

          5.2.4 Phase 3 Premises.

               (a) In the event Tenant elects to occupy the Phase 3 Premises (which shall include all, and not less than all, of the remainder unoccupied portion of the Expansion Building) before the Phase 3 Estimated Delivery Date, Tenant shall deliver to Landlord at least five (5) business days a written notice setting forth the date that Tenant intends to occupy the Phase 3 Premises (collectively, the “Phase 3 Commencement Date Notice”).

               (b) Landlord shall tender possession of the Phase 3 Premises to Tenant upon the Phase 3 Commencement Date. On the Phase 3 Commencement Date, Landlord and Tenant shall each execute and deliver to the other factually correct written acknowledgement of the actual Phase 3 Commencement Date and the Expiration Date when established, in the form Exhibit F, and shall attach it to this Lease as Exhibit F-3. Failure to execute and deliver such

8

acknowledgement, however, shall not affect the Phase 3 Commencement Date or Tenant’s liability hereunder.

          5.2.5 Tenant’s Termination and Abatement Rights.

               (a) First Milestone Termination Right. Notwithstanding the foregoing, in the event Landlord has not commenced the grading of the land where the Expansion Building will be located (“Grading Work”) by September 1, 2007, as such date may be equitably extended to reflect any Tenant Delay and any Force Majeure delays (“Outside Date Termination Date”), then Tenant shall have the right to terminate this Lease by notice to Landlord given no later than thirty (30) days following such date, at which time neither party shall have any further right or obligation hereunder (except for those terms and provisions which expressly survive the expiration or sooner termination of this Lease).

               (b) Second Milestone Abatement and Termination Right. Notwithstanding the foregoing, in the event that Substantial Completion of the Tenant Improvements has not occurred by October 1, 2008, as such date may be equitably extended to reflect any Tenant Delay and any Force Majeure delays (the “TI Completion Outside Date”), then Tenant shall be entitled to one (1) day of abatement of Expansion Premises Basic Annual Rent for the Phase 1 Premises for every day past the applicable TI Completion Outside Date that Substantial Completion of the Tenant Improvements has not occurred. In the event that Substantial Completion of the Tenant Improvements has not occurred by October 1, 2009, as such date may be equitably extended to reflect any Tenant Delay and any Force Majeure delays (the “TI Completion Termination Date”), then Tenant shall have the right to terminate this Lease by notice to Landlord given no later than thirty (30) days following such date, at which time neither party shall have any further right or obligation hereunder (except for those terms and provisions which expressly survive the expiration or sooner termination of this Lease); provided, however, for purposes of this Section 5.2.5(b), in no event shall the period of excused delay for Force Majeure exceed ninety (90) days in the aggregate.

6. Rent.

     6.1. Diversified Building Premises. Starting on the Execution Date, Tenant shall pay to Landlord as Basic Annual Rent for the Diversified Building Premises, the rent set forth on the rent schedule attached hereto as Schedule 1, subject to adjustments in accordance with Article 7. The Diversified Building Premises Basic Annual Rent shall be paid in equal monthly installments on or before the first day of the applicable month.

     6.2. Expansion Premises. Starting on the Phase 1 Commencement Date, Tenant shall pay to Landlord as Basic Annual Rent for the Expansion Premises, the product of (a) the rate per rentable square feet set forth in Section 2.3 (as adjusted in accordance with Article 7), and (b) the rentable square feet of the Phases that are included in the Expansion Premises from time to time, subject to adjustment pursuant to the terms of this Lease, including, without limitation: (i) the Expansion Premises Basic Annual Rent shall increase on the Phase 2 Commencement Date by the product of (1) the number of rentable square feet of the Phase 2 Premises and (2) the same Expansion Premises Basic Annual Rent rate per rentable square foot that applies to the Expansion Premises from time to time; (ii) the Expansion Premises Basic Annual Rent shall increase on the Phase 3 Commencement Date by the product of (1) the number of rentable square feet of the Phase 3 Premises and (2) the same Expansion Premises Basic Annual Rent rate per rentable square foot that applies to the Expansion Premises from time to time; and (iii) the biennial rent adjustments in accordance the provisions of Article 7 hereof. Expansion Premises Basic Annual Rent and the TI Allowance Amount shall be paid in equal monthly installments on or before the first day of the applicable month.

     6.3. In addition to Basic Annual Rent, from and after the Commencement Date, Tenant shall pay to Landlord as additional rent (“Additional Rent”) at times hereinafter specified in this Lease (a) amounts related to Insurance Costs, Utility Costs and Taxes (each as defined below) and (b) any other amounts that Tenant agrees to pay under the provisions of this Lease that are owed to Landlord, including, without limitation, any and all other sums that may become due by reason of any default of Tenant or failure on Tenant’s part to comply with the agreements, terms, covenants and conditions of this Lease to be performed by Tenant, after notice and the lapse of any applicable cure periods.

9

     6.4. Basic Annual Rent (including the Diversified Building Premises Basic Annual Rent and the Expansion Premises Basic Annual Rent) and Additional Rent shall together be denominated “Rent.” Rent shall be paid to Landlord, without, except as otherwise provided herein, abatement, deduction or offset, in lawful money of the United States of America at the office of Landlord as set forth in Section 2.10 or to such other person or at such other place as Landlord may from time designate in writing. In the event the Commencement Date for any Phase commences or ends on a day other than the first day of a calendar month, then the Rent for such fraction of a month shall be prorated for such period on the basis of a thirty (30) day month and shall be paid at the then-current rate for such fractional month.

7. Rent Adjustments.

     7.1. Initial Term.

          7.1.1 Diversified Building Premises. The Diversified Building Premises Basic Annual Rent per rentable square foot of the Diversified Building Premises shall be increased in accordance with Schedule 1 attached hereto.

          7.1.2 Expansion Premises. The Expansion Premises Basic Annual Rent per rentable square foot of the Expansion Premises shall be increased on every other anniversary (i.e., the second anniversary, the fourth anniversary, the sixth anniversary, etc.) of the Phase 1 Commencement Date by five percent (5%) of the Expansion Premises Basic Annual Rent per rentable square foot of the Expansion Premises immediately preceding such increase. The monthly installment of Expansion Premises Basic Annual Rent that is due for the month in which each such adjustment occurs (the installment due immediately before such month) shall be the first installment that will be increased to reflect such increase in Expansion Premises Basic Annual Rent.

     7.2. Extended Term.

          7.2.1 Diversified Building Premises. The Diversified Building Premises Basic Annual Rent for the Diversified Building Premises shall be adjusted on the first (1^st) day of each Extended Term to the amount calculated in accordance with Section 42.1, and shall be adjusted every twenty-four (24) months thereafter by five percent (5%) of the Diversified Building Premises Basic Annual Rent per rentable square foot of the Diversified Building Premises immediately preceding such increase. The monthly installment of the Diversified Building Premises Basic Annual Rent that is due for the month in which each such adjustment occurs (the installment due immediately before such month) shall be the first installment that will be increased to reflect such increase in the Diversified Building Premises Basic Annual Rent.

          7.2.2 Expansion Premises. The Expansion Premises Basic Annual Rent for the Expansion Premises shall be adjusted on the first (1^st) day of each Extended Term to the amount calculated in accordance with Section 42.1, and shall be adjusted every twenty-four (24) months thereafter by five percent (5%) of the Expansion Premises Basic Annual Rent per rentable square foot of the Expansion Premises immediately preceding such increase. The monthly installment of the Expansion Premises Basic Annual Rent that is due for the month in which each such adjustment occurs (the installment due immediately before such month) shall be the first installment that will be increased to reflect such increase in the Expansion Premises Basic Annual Rent.

8. Taxes.

     8.1. Commencing with the Commencement Date and continuing for each calendar year or, at Landlord’s option, tax year (each such “tax year” being a period of twelve (12) consecutive calendar months for which the applicable taxing authority levies or assesses Taxes), for the balance of the Term, Tenant shall pay to Landlord the amount of all Taxes levied and assessed for any such year upon the Property (including the Diversified Space). “Taxes” shall mean all government impositions including, without limitation, property tax costs consisting of real and personal property taxes and assessments (including amounts due under any improvement bond upon the Property or any portion thereof, including the Parcel or parcels of real property upon which the Buildings are located or assessments levied in lieu thereof) imposed by any federal, state, regional, local or municipal governmental authority, agency or subdivision (each, a “Governmental Authority”) on the Property or improvements thereon, any tax on or

10

measured by gross rentals received from the rental of space in the Buildings, or tax based on the square footage of the Premises or the Buildings as well as any parking charges, utilities surcharges, or any other costs levied, assessed or imposed by, or at the direction of, or resulting from statutes or regulations, or interpretations thereof, promulgated by any Governmental Authority in connection with the use or occupancy of the Premises or the parking facilities exclusively serving the Premises; any tax on this transaction or this Lease; provided, however, that “Taxes” shall in no event include any franchise or federal or state income tax, excess profit taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes or any tax based on net rentals received from the rental of space in the Buildings. Any amount paid by Tenant for any partial year of the Term shall be prorated on the basis of the number of days of such partial year. Payment shall be made in the following manner: Tenant shall pay to Landlord the amounts owed under this Article 8 within thirty (30) days after Landlord gives notice to Tenant of the amount of such Taxes payable by Tenant (or not less than fifteen (15) days prior to delinquency, whichever is later). Landlord also shall provide Tenant with a copy of the applicable tax bill or tax statement from the relevant taxing authority. Notwithstanding the foregoing, if Applicable Laws allow any such Taxes to be paid in installments, then Tenant may make such payments to Landlord in installments, provided that each such installment shall be payable to Landlord not less than ten (10) days prior to the date upon which payment of the applicable installment to the taxing authority becomes delinquent. In addition to any other amounts due from Tenant to Landlord, if Tenant fails to pay Taxes to Landlord as herein required, Tenant shall pay to Landlord the amount of any interest, penalties or late charges imposed by any governmental authority for late payment. “Applicable Laws” means all federal, state, municipal and local laws, codes, ordinances, rules and regulations of Governmental Authorities, committees, associations, or other regulatory committees, agencies or governing bodies having jurisdiction over the Property, Landlord or Tenant, including both statutory and common law and hazard waste rules and regulations.

          8.1.1 Tenant shall have the right, by appropriate proceedings, to protest or contest in good faith any assessment or reassessment of Taxes, any special assessment, or the validity of any Taxes or of any change in assessment or tax rate; provided, however, that prior to any such challenge Tenant must either (a) pay the Taxes alleged to be due in their entirety and seek a refund from the appropriate authority or (b) post a bond in an amount sufficient to ensure full payment of the Taxes, including any potential interest, late charge and penalties. Upon a final determination with respect to any such contest or protest, Tenant shall promptly pay to the appropriate Governmental Authority all sums found to be due with respect thereto. In any such protest or contest, Tenant may act in its own name, and at the request of Tenant, Landlord shall cooperate with Tenant in any way Tenant may reasonably require in connection with such contest or protest, including signing such documents as Tenant reasonably shall request, provided that such cooperation shall be at no expense to Landlord and shall not require Landlord to attend any appeal or other hearing. Any such contest or protest shall be at Tenant’s sole expense, and if any penalties, interest or late charges become payable with respect to the Taxes as a result of such contest or protest, Tenant shall pay the same.

          8.1.2 If Tenant obtains a refund as the result of Tenant’s protest or contest, and subject to Tenant’s obligation to pay Landlord’s costs (if any) associated therewith, Tenant shall be entitled to such refund to the extent it relates to the Property during the Term.

     8.2. If, at any time during the Term under the laws of any Governmental Authority, a tax or excise on rent or any other tax howsoever described is levied or assessed by any such political body against Landlord on account of rentals payable to Landlord hereunder, such tax or excise shall be considered “Taxes” for the purposes of this Article 8, although any amount assessed against Landlord as state or federal income tax shall not be deemed “Taxes.”

     8.3. To the extent Landlord is required by a lender, Tenant shall timely pay all tax and insurance impound payments due on the Property.

     8.4. Taxes on Tenant’s Property.

          8.4.1 Tenant shall pay at least twenty (20) days prior to delinquency any and all taxes levied against any personal property or trade fixtures placed by Tenant in or about the Property.

11

          8.4.2 If any such taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property or, if the assessed valuation of the Buildings is increased by inclusion therein of a value attributable to Tenant’s personal property or trade fixtures, and if Landlord, after written notice to Tenant, pays the taxes based upon any such increase in the assessed valued of the Buildings, then Tenant shall, upon demand, repay to Landlord the taxes so paid by Landlord.

     8.5. Cut-Off Date. Notwithstanding anything herein to the contrary, Tenant shall not be responsible for Taxes attributable to any calendar year which are first billed to Tenant more than eighteen (18) months after the expiration of the applicable calendar year, except with respect to supplemental Taxes.

9. [Intentionally Omitted].

10. Security Deposit.

     10.1. Pursuant to the Original Illumina Lease, Tenant has deposited with Landlord an amount equal to $1,911,855 as the security deposit under the Original Illumina Lease (the “Original Illumina Lease Security Deposit”), and (a) from and after the Execution Date, Landlord shall continue to hold a portion of the Original Illumina Lease Security Deposit in an amount equal to $40,836.75 (the “Security Deposit”), in accordance with the terms and conditions of this Section 10, (b) from and after the Execution Date, Landlord shall hold a portion of Original Illumina Lease Security Deposit equal to $865,177.50 in accordance with the terms and conditions of Section 8 of the Illumina Lease, and (c) Landlord shall return the remaining portion of the Original Illumina Lease Security Deposit in an amount equal to $1,005,840.75 to Tenant.

     10.2. The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease to be kept and performed by Tenant during the period commencing on the Execution Date and ending upon the expiration or termination of this Lease. In addition, Tenant shall deposit the following amounts with Landlord and the Security Deposit shall be increased by such amounts: (a) a sum equal to $343,274.40 upon commencement of construction of the Landlord’s Construction Work, (b) a sum equal to $180,600.00 on the Phase 2 Commencement Date, and (c) a sum equal to $189,630.00 on the Phase 3 Commencement Date. If Tenant defaults with respect to any provision of this Lease, including, but not limited to, any provision relating to the payment of Rent, then Landlord may (but shall not be required to) use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default. If any portion of the Security Deposit is so used or applied, then Tenant shall, within twenty (20) days following demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep this Security Deposit separate from its general fund, and Tenant shall not be entitled to interest on the Security Deposit. The provisions of this Article 10 shall survive the expiration or earlier termination of this Lease.

     10.3. In the event Landlord receives documentation from Tenant that demonstrates to Landlord’s reasonable satisfaction that Tenant has achieved a rating of “BBB” or better from Standard & Poor’s Corporation (“S&P”), or “Baa” or better from Moody’s Investors Service, Inc. (“Moody’s”)(or in each case any successor thereof), and Tenant is not then in Default, Landlord shall return a portion of the Security Deposit so that the remaining Security Deposit equals one (1) month of Basic Annual Rent for the entire Premises to Tenant; provided, however, in the event (a) Tenant subsequently has neither a S&P rating of “BBB” or better nor a Moody’s rating of “Baa” or better, or (b) Tenant assigns its interest in this Lease to another person or entity in accordance with Section 27 hereof, unless such assignee satisfies the requirements set forth in this Section 10.3, Tenant shall, within fifteen (15) days after written notice thereof, deposit an amount with Landlord sufficient to restore said Security Deposit to the amount set forth in Section 2.7 and Tenant’s failure to do so shall constitute a Default of this Lease.

     10.4. In the event of bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings.

12

     10.5. Landlord may deliver to any purchaser of Landlord’s interest in the Property the funds deposited hereunder by Tenant, and thereupon Landlord shall be discharged from any further liability with respect to such deposit. This provision shall also apply to any subsequent transfers.

     10.6. If Tenant is not then in Default under this Lease nor is any event then occurring which with the giving of notice or the passage of time, or both, would constitute a Default hereunder, then the Security Deposit, or any balance thereof, shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within thirty (30) days after the expiration or earlier termination of this Lease.

     10.7. The Security Deposit may be in the form of cash, a letter of credit or any other security instrument acceptable to Landlord in its sole discretion. Tenant may at any time, except during Default, deliver a letter of credit (“L/C Security”) as the entire Security Deposit, as follows.

          10.7.1 If Tenant elects to deliver L/C Security, then Tenant shall provide Landlord, and maintain in full force and effect throughout the Term, a letter of credit in substantially the form of Exhibit K issued by an issuer reasonably satisfactory to Landlord, in the amount of the Security Deposit, with an initial term of at least one year. If, at the Expiration Date, any Rent remains uncalculated or unpaid, then: (a) Landlord shall with reasonable diligence complete any necessary calculations; (b) Tenant shall extend the expiry date of such L/C Security from time to time as Landlord reasonably requires; and (c) in such extended period, Landlord shall not unreasonably refuse to consent to an appropriate reduction of the L/C Security. Tenant shall reimburse Landlord’s legal costs (as estimated by Landlord’s counsel) in handling Landlord’s acceptance of L/C Security or its replacement or extension

          10.7.2 If Tenant delivers to Landlord satisfactory L/C Security in place of the entire Security Deposit, Landlord shall promptly remit to Tenant any cash Security Deposit Landlord previously held.

          10.7.3 Landlord may draw upon the L/C Security, and hold and apply the proceeds in the same manner and for the same purposes as the Security Deposit, if: (a) an uncured Default exists; (b) as of the date thirty (30) days before any L/C Security expires (even if such scheduled expiry date is after the Expiration Date) Tenant has not delivered to Landlord an amendment or replacement for such L/C Security, reasonably satisfactory to Landlord, extending the expiry date to the earlier of (i) six (6) months after the then-current Expiration Date or (ii) the date one year after the then-current expiry date of the L/C Security; (c) the L/C Security provides for automatic renewals, Landlord asks the issuer to confirm the current L/C Security expiry date, and the issuer fails to do so within ten (10) business days; (d) Tenant fails to pay (when and as Landlord reasonably requires) any bank charges for Landlord’s transfer of the L/C Security; or (e) the issuer of the L/C Security ceases, or announces that it will cease, to maintain an office in the city where Landlord may present drafts under the L/C Security. This Section does not limit any other provisions of this Lease allowing Landlord to draw the L/C Security under specified circumstances.

          10.7.4 Tenant shall not seek to enjoin, prevent, or otherwise interfere with Landlord’s draw under L/C Security, even if it violates this Lease. Tenant acknowledges that the only effect of a wrongful draw would be to substitute a cash Security Deposit for L/C Security, causing Tenant no legally recognizable damage. Landlord shall hold the proceeds of any draw in the same manner and for the same purposes as a cash Security Deposit. In the event of a wrongful draw, the parties shall cooperate to allow Tenant to post replacement L/C Security simultaneously with the return to Tenant of the wrongfully drawn sums, and Landlord shall upon request confirm in writing to the issuer of the L/C Security that Landlord’s draw was erroneous.

          10.7.5 If Landlord transfers its interest in the Property, then Tenant shall at Tenant’s expense, within ten (10) business days after receiving a request from Landlord, deliver (and, if the issuer requires, Landlord shall consent to) an amendment to the L/C Security naming Landlord’s grantee as substitute beneficiary; provided, however, in the event Landlord transfers its interest in the Property more than once in a twelve (12) month period, Landlord shall pay any fee owed to the issuing bank in connection with any such additional transfer. If the required Security changes while L/C Security is in force, then Tenant shall deliver (and, if the issuer requires, Landlord shall consent to) a corresponding amendment to the L/C Security.

13

11. Use.

     11.1. Tenant shall use the Premises for the purpose set forth in Section 2.8, and shall not use the Premises, or permit or suffer the Premises to be used, for any other purpose without Landlord’s prior written consent, which consent Landlord may withhold in its reasonable discretion.

     11.2. Tenant shall not use or occupy the Property in violation of Applicable Laws; zoning ordinances; or the certificate of occupancy issued for the Buildings, and shall, upon five (5) days’ written notice from Landlord, discontinue any use of the Property that is declared or claimed by any Governmental Authority having jurisdiction to be a violation of any of the above, or that Landlord has a reasonable basis to believe that such use violates any of the above and Landlord identifies such basis in its notice to Tenant. Tenant shall comply with any direction of any Governmental Authority having jurisdiction that shall, by reason of the nature of Tenant’s use or occupancy of the Property, impose any duty upon Tenant with respect to the Property or with respect to the use or occupation thereof.

     11.3. Tenant shall not do or permit to be done anything that will invalidate or increase the cost of any fire, environmental, extended coverage or any other insurance policy covering the Property, and shall comply with all rules, orders, regulations and requirements of the insurers of the Property, and Tenant shall promptly, upon demand, reimburse Landlord for any additional premium charged for such policy by reason of Tenant’s failure to comply with the provisions of this Article 11.

     11.4. Tenant shall, at its sole cost and expense, promptly and properly observe and comply with all present and future orders, regulations, directions, rules, laws, ordinances, and requirements of all Governmental Authorities (including, without limitation, state, municipal, county and federal governments and their departments, bureaus, boards and officials) arising from the use or occupancy of the Property, including, without limitation, the requirements of Americans with Disabilities Act of 1990 (together with regulations promulgated pursuant thereto, the “ADA”). Tenant’s obligations under this Section 11.4 shall include any Alterations to the Property (including (a) the Diversified Building and, (b) from and after the Phase 1 Commencement Date, the Expansion Building) that Tenant is required or elects to make pursuant to the terms of this Lease; provided, however, Landlord shall be responsible for ADA compliance of the Landlord’s Construction Work and the Tenant Improvements.

     11.5. Tenant shall keep all doors opening onto public corridors closed, except when in use for ingress and egress.

     11.6. No additional locks or bolts of any kind shall be placed upon any of the doors or windows by Tenant, nor shall any changes be made to existing locks or the mechanisms thereof without Landlord’s prior written consent. Tenant shall, upon termination of this Lease, return to Landlord all keys to offices and restrooms either furnished to or otherwise procured by Tenant. In the event any key so furnished to Tenant is lost, Tenant shall pay to Landlord the cost of replacing the same or of changing the lock or locks opened by such lost key if Landlord shall deem it necessary to make such change

     11.7. No awnings or other projections shall be attached to any outside wall of the Buildings. No curtains, blinds, shades or screens shall be attached to or hung in, or used in connection with, any window or door of the Buildings other than Landlord’s standard window coverings. Neither the interior nor exterior of any windows shall be coated or otherwise sunscreened without Landlord’s prior written consent, nor shall any bottles, parcels or other articles be placed on the windowsills. No equipment, furniture or other items of personal property shall be placed on any exterior balcony without Landlord’s prior written consent.

     11.8. Subject to Diversified’s right to place signs on the Property in accordance with Section 32 of the Diversified Lease, Tenant shall, at Tenant’s sole cost and expense, have the exclusive right to install the maximum amount of any legally permitted signage on the Property (including any building thereon) (“Signage”), which Signage shall be subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Tenant shall keep the Signage in good condition and repair. The size, design, and other physical aspects of any sign shall be subject to Landlord’s written approval prior to installation, which approval will not unreasonably be withheld, any covenants, conditions, or restrictions

14

encumbering the Property and, any Applicable Laws. The cost of the sign(s), including but not limited to the permitting, installation, maintenance and removal thereof shall be at Tenant’s sole cost and expense. If Tenant fails to maintain its sign(s), or if Tenant fails to remove such sign(s) upon termination of this Lease, or fails to repair any damage caused by such removal (including without limitation, painting the damaged portions of the Buildings and any other portions of the Buildings that Landlord reasonably determines in good faith shall be painted so that repainting the damaged portion of the Buildings does not adversely affect the visual appearance of the Buildings, if required by Landlord; provided, however, in no event shall Landlord require Tenant to repaint an entire Building), Landlord may do so at Tenant’s expense. Tenant shall on demand reimburse Landlord for all costs incurred by Landlord to effect such removal, which amounts shall be deemed Additional Rent and shall include without limitation, all sums disbursed, incurred or deposited by Landlord, including Landlord’s costs, expenses and actual attorneys’ fees with interest thereon. Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising directly or indirectly out of Tenant’s failure to perform any of its obligations under this Section 11.8.

     11.9. Tenant shall only place equipment within the Premises with floor loading consistent with the structural design of the Buildings without Landlord’s prior written approval, and such equipment shall be placed in a location designed to carry the weight of such equipment.

     11.10. Tenant shall not (a) use or allow the Property to be used for any unlawful or reasonably objectionable purposes or (b) cause, maintain or permit any nuisance or waste in, on or about the Property (other than the Diversified Space).

     11.11. Except for Landlord’s Construction Work and Tenant Improvement work, Tenant shall be responsible for all liabilities, costs and expenses arising out of or in connection with the compliance of the Property (other than the Diversified Space) with the ADA, and Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising out of any failure of the Property (other than the Diversified Space) to comply with the ADA. Notwithstanding the foregoing, Landlord represents and warrants that upon Substantial Completion of Landlord’s Construction Work and the Tenant Improvement work, the Expansion Building shall comply with all Applicable Laws, including the ADA and any compliance costs as a result of a breach of this representation and warranty shall be at Landlord’s sole cost and expense and Landlord shall indemnify, defend and hold harmless Tenant from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising out of any failure of the Landlord’s Construction Work or the Tenant Improvements to comply with the ADA. The provisions of this Section 11.11 shall survive the expiration or earlier termination of this Lease.

From and after the Commencement Date, (a) Tenant shall be responsible for paying all amounts with respect to Taxes, Insurance Costs, Utility Costs and any other costs and expenses Landlord is required to pay in connection with the Diversified Space in accordance with Article 9 of the Diversified Lease, and (b) Landlord assumes, and is responsible for performing, all of the obligations of the landlord under and related to the Diversified Lease (other than the payment of expenses in accordance with Section 12.1(a) above).

Diversified shall have the non-exclusive right to use the Diversified Areas 24 hours a day, 7 days a week other than Diversified’s exclusive right to use the 5 covered reserved parking spaces pursuant to the Diversified Lease. Tenant hereby agrees that it shall not regulate, restrict or charge any fees in connection with Diversified’s use of the Diversified Areas.

     12.4. Subdivision. Landlord may subdivide Parcel 3 so that it will consist of two lots that may be legally conveyed in accordance with California’s Subdivision Map Act. At Landlord’s request, Tenant shall execute, acknowledge and deliver such further instruments and do such further acts as may be necessary to modify the subdivision of such property. Tenant shall not oppose or object to any changes or modifications to the subdivision for such property.

13. Brokers.

     13.1. Tenant represents and warrants that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease other than Steve Rosetta and Ted Simpson, Cushman & Wakefield (“Tenant’s Broker”), and that it knows of no other real estate broker or agent that is or might be entitled to a commission in connection with this Lease.

Landlord shall compensate Landlord’s Broker in relation to this Lease pursuant to the Commission Agreement.

     13.3. Tenant acknowledges and agrees that the employment of brokers by Landlord is for the purpose of solicitation of offers of leases from prospective tenants and that no authority is granted to any broker to furnish any representation (written or oral) or warranty from Landlord unless expressly contained within this Lease. Landlord is executing this Lease in reliance upon Tenant’s representations, warranties and agreements contained within Section 13.1.

     13.4. Tenant agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any other broker or agent, other than Tenant’s Broker, employed or engaged by it or claiming to have been employed or engaged by Tenant. Landlord agrees to indemnify, defend and hold Tenant harmless from any and all cost or liability for compensation claimed by any other broker or agent, other than Landlord’s Broker, employed or engaged by it or claiming to have been employed or engaged by Landlord.

14. Holding Over.

     14.1. If, with Landlord’s prior written consent, Tenant holds possession of all or any part of the Property after the Term, Tenant shall become a tenant from month to month after the expiration or earlier termination of the Term, and in such case Tenant shall continue to pay (a) the Basic Annual Rent in accordance with Article 6, as adjusted in accordance with Article 7, and (b) any amounts for which Tenant would otherwise be liable under this Lease if this Lease were still in effect, including, without limitation, payments for Taxes and insurance. Any such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein.

     14.2. Notwithstanding the foregoing, if Tenant remains in possession of the Property after the expiration or earlier termination of the Term without Landlord’s prior written consent, Tenant shall become a tenant at sufferance subject to the terms and conditions of this Lease, except that the per diem Basic Annual Rent shall be equal to: (a) for the first three (3) months that Tenant remains in possession of the Property after the expiration or earlier termination of this Lease, one hundred twenty-five percent (125%) of the Basic Annual Rent in effect during the last thirty (30) days of the Term; and (b) for any time thereafter that Tenant remains in possession of the Property after the expiration or earlier termination of this Lease, one hundred

16

fifty percent (150%) of the Basic Annual Rent in effect during the last thirty (30) days of the Term.

     14.3. Acceptance by Landlord of Rent after the expiration or earlier termination of the Term shall not result in an extension, renewal or reinstatement of this Lease.

15. Property Management Fee. Tenant shall pay to Landlord on the first day of each calendar month of the Term, as Additional Rent, the “Property Management Fee,” which shall equal one percent (1%) of the Basic Annual Rent due from Tenant.

16. Condition of Premises and the Property. Except as otherwise provided herein, Tenant acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the condition of the Premises, the Property or with respect to the suitability of the Premises for the conduct of Tenant’s business.

17. Regulations and Parking and Recreation Facilities.

     17.1. Tenant shall faithfully observe and comply with the rules and regulations adopted by Landlord and attached hereto as Exhibit H, together with such other reasonable and nondiscriminatory rules and regulations as are hereafter promulgated by Landlord in its reasonable discretion (the “Rules and Regulations”).

     17.2. Subject to Diversified’s rights under Section 12.3, Tenant shall have the right to use, at no additional cost, the parking facilities serving the Premises. As part of Landlord’s Construction Work, the Property shall contain sufficient parking to comply with applicable zoning requirements.

     17.3. Tenant shall, at Tenant’s sole cost and expense, comply with the terms and conditions set forth in, and perform each of the obligations of the Parcel 3 Owner (as defined in the REA) described in, Sections 3, 4.1, 4.2, 4.3, 4.4, 4.8, 7, 8, 9, 11.3, 11.10, 11.11 and 11.12 of the Reciprocal Easement Agreement attached hereto as Exhibit L (the “REA”), in accordance with the terms of conditions of the REA as if Tenant were the Parcel 3 Owner.

     17.4. Subject to Section 18.5 and provided there is no material adverse impact on Tenant’s Permitted Use and access to the Premises (including the parking facilities), Landlord reserves the right to subdivide the real property; provided, however, that such right shall be exercised in a way that does not materially adversely affect Tenant’s beneficial use and occupancy of the Premises, including Tenant’s Permitted Use and Tenant’s access to the Premises (including the parking facilities).

     17.5. Tenant shall, and shall cause Tenant’s Agents to, faithfully observe and comply with any rules and regulations adopted pursuant to Section 4.7 of the REA (the “Recreation Facilities Rules and Regulations”). Landlord has the right to refuse to allow Tenant’s Agents to access the Recreation Facilities if such Tenant’s Agent has not complied with the applicable Recreation Facilities Rules and Regulations after receiving written notice of such failure to comply.

     17.6. Tenant shall have the right to use the Recreation Facilities during the hours reasonably established by Landlord as the operating hours of the Recreation Facilities. Notwithstanding anything to the contrary in this Lease, Landlord shall have no responsibility to Tenant or Tenant’s Agents (as defined below), for any accidents, claims, demands, liabilities, causes of action, judgments, costs, liens, damages, injuries, suits, losses or expenses, including attorneys’ fees, of any nature, kind or description, arising out of, caused by, or resulting from Tenant or Tenant’s Agent’s use of the Recreational Facilities or the negligence of Landlord Parties (as defined in Section 22.3) or Tenant’s Agents in connection with the operation and maintenance of such Recreational Facilities.

     17.7. So long as this Lease is in full force and effect, Landlord shall not amend or modify the REA without first obtaining: (a) the prior written consent of the original Tenant hereunder (but not any assignee or subtenant), which consent shall not be unreasonably withheld,

17

conditioned or delayed, and (b) solely with respect to amendments or modifications that could reasonably be expected to have a material adverse effect on obligations assumed by any successors and assigns of Tenant under the REA, the prior written consent of any such successors and assigns, which consent shall not be unreasonably withheld, conditioned or delayed. All amendments or modifications which result in an increase of the costs and expenses to be incurred by Tenant under Section 17.3 shall be deemed material and adverse.

18. Utilities and Services.

     18.1. Tenant shall, at Tenant’s sole cost and expense, procure and maintain contracts, with copies furnished promptly to Landlord after execution thereof, in customary form and substance for, and with contractors specializing and experienced in, the maintenance of the following equipment and improvements, if any, if and when installed on the Property: (a) HVAC equipment, (b) boilers and pressure vessels, (c) fire extinguishing systems, including fire alarm and smoke detection devices, (d) landscaping and irrigation systems, (e) roof coverings and drains, (f) clarifiers, (g) basic utility feeds to the perimeter of the Buildings, and (h) any other equipment reasonably required by Landlord. Notwithstanding the foregoing, in the event Tenant fails to maintain the contracts required under this Section 18.1 within one (1) business day after Landlord provides Tenant written notice of such failure, Landlord reserves the right, upon notice to Tenant, to procure and maintain any or all of such contracts, and if Landlord so elects, Tenant shall reimburse Landlord, upon demand, for the actual documented costs thereof.

     18.2. Within sixty (60) days after the Commencement Date, and within sixty (60) days after the beginning of each calendar year during the Term, Landlord shall give Tenant a written estimate for such calendar year of the cost of utilities for the Property (including the Diversified Space), if not separately metered (“Utility Costs”), and insurance provided by Landlord for the Property (including the Diversified Space) (“Insurance Costs”). Tenant shall pay such estimated amount to Landlord in advance in equal monthly installments. Within ninety (90) days after the end of each calendar year, Landlord shall furnish to Tenant a statement showing in reasonable detail the costs incurred by Landlord for Utility Costs and Insurance Costs for the Property (including the Diversified Space) during such year (the “Annual Statement”), and Tenant shall pay to Landlord the costs incurred in excess of the payments previously made by Tenant within thirty (30) days of receipt of the Annual Statement. In the event that the payments previously made by Tenant for Utility Costs and Insurance Costs for the Property (including the Diversified Space) exceed Tenant’s obligation, such excess amount shall be credited by Landlord to the Rent or other charges next due and owing, provided that, if the Term has expired, Landlord shall remit such excess amount to Tenant. In the event Tenant disputes the amounts of any Annual Statement for the particular calendar year delivered by Landlord to Tenant and Tenant is not in Default hereunder, Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have Tenant’s authorized employees inspect, at Landlord’s office in San Diego County during normal business hours, Landlord’s books, records and supporting documents concerning the expenses set forth in such Annual Statement; provided, however, Tenant shall have no right to conduct such inspection, have an audit performed by the Accountant as described below, or object to or otherwise dispute the amount of the expenses set forth in any such Annual Statement unless Tenant notifies Landlord of such objection and dispute, completes such inspection, and has the Accountant commence and complete such audit within one hundred and eighty (180) days immediately following Landlord’s delivery of the particular Annual Statement in question (the “Review Period”); provided, further, that notwithstanding any such timely objection, dispute, inspection, and/or audit, and as a condition precedent to Tenant’s exercise of its right of objection, dispute, inspection and/or audit as set forth in this Section 18.2, Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts as required by the provisions of this Lease in accordance with such Annual Statement. However, such payment may be made under protest pending the outcome of any audit which may be performed by the Accountant as described below. In connection with any such inspection by Tenant, Landlord and Tenant shall reasonably cooperate with each other so that such inspection can be performed pursuant to a mutually acceptable schedule. If after such inspection and/or request for documentation, Tenant still disputes the amount of the expenses set forth in the Annual Statement, Tenant shall have the right, within the Review Period, to cause an independent certified public accountant selected by Tenant and compensated on a non-contingency fee basis (the “Accountant”) to complete an audit of Landlord’s books and records to determine the proper amount of the expenses incurred and amounts payable by Tenant for the calendar year which is the subject of such Annual Statement. Such audit by the Accountant shall be final and binding upon Landlord and Tenant. If such audit reveals that Landlord has

18

over-charged Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is subsequently determined that Landlord’s original Annual Statement which was the subject of such audit overstated expenses by five percent (5%) or more of the actual expenses which were the subject of such audit. The payment by Tenant of any amounts pursuant to this Section 18.2 shall not preclude Tenant from questioning, during the Review Period, the correctness of the particular Annual Statement in question provided by Landlord, but the failure of Tenant to object thereto, conduct and complete its inspection and have the Accountant conduct the audit as described above prior to the expiration of the Review Period for such Annual Statement shall be conclusively deemed Tenant’s approval of the Annual Statement in question and the amount of expenses shown thereon. If following Tenant’s delivery to Landlord of a written request to make Landlord’s books and records regarding the expenses reasonably available to Tenant and/or the Accountant to conduct any such inspection and/or audit described above in this Section 18.2, Landlord fails to make Landlord’s books reasonably available for such purposes during Landlord’s normal business hours, and such failure continues for five (5) business days after Tenant notifies Landlord thereof, then the Review Period shall be extended one (1) day for each such additional day that Tenant and/or the Accountant, as the case may be, is so prevented from accessing such books and records. In connection with any inspection and/or audit conducted by Tenant pursuant to this Section 18.2, Tenant agrees to keep, and to cause all of Tenant’s employees and consultants and the Accountant to keep, all of Landlord’s books and records and the audit, and all information pertaining thereto and the results thereof, strictly confidential (except if required by any court to disclose such information or if such information is available from an inspection of public records).

     18.3. Tenant shall make all arrangements for and pay for all water, sewer, gas, heat, light, power, telephone service and any other service or utility Tenant required at the Property (including the Diversified Space). Landlord shall not be liable for, nor shall any eviction of Tenant result from, the failure to furnish any utility or service, whether or not such failure is caused by Force Majeure or Landlord’s inability, despite the exercise of reasonable diligence, to furnish any such utility or service. Except as provided in Section 18.5, in the event of such failure, Tenant shall not be entitled to termination of this Lease, any abatement or reduction of Rent, or relief from the operation of any covenant or agreement of this Lease. Tenant shall pay for, prior to delinquency of payment therefor, any utilities and services that may be furnished to the Property (including the Diversified Space) during or, if Tenant occupies any portion of the Premises after the expiration or earlier termination of the Term, after the Term.

     18.4. From and after the Commencement Date, Tenant shall be responsible for paying all amounts with respect to Insurance Costs, Utility Costs, Taxes and other amounts for which Tenant is responsible under this Lease (other than Expansion Premises Basic Annual Rent) for the Expansion Premises as if it was part of the Expansion Premises on the Commencement Date.

     18.5. Notwithstanding the foregoing and subject to Sections 17 and 35, if because of (i) any repair, maintenance, alteration, development or construction performed by Landlord after the Commencement Date, which substantially interferes with Tenant’s use of the Premises and which was not caused by Tenant, (ii) any material interference by Landlord with Tenant’s access to the Premises (including the parking facilities) that is not caused by Tenant, or (iii) the presence of Hazardous Materials in, on or around the Premises in connection with the Landlord’s Construction Work or the Tenant Improvements which (a) is not caused by Tenant, and (b) poses a health risk to occupants of the Premises (each, an “Adverse Condition”), Tenant is unable to conduct its business in a reasonable manner in a material portion of the Premises as a direct result of the Adverse Condition and Tenant therefore actually does not occupy or use such portion of the Premises, as the case may be, and such condition persists for more than the “Interruption Period” (as defined below), then following the Interruption Period, Tenant shall be entitled to an abatement of Rent for the portion of the Premises rendered untenantable. However, in the event that the remaining portion of the Premises is not sufficient to allow Tenant to conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Interruption Period during which Tenant is so prevented from effectively conducting its business therein, the Rent for the entire Premises shall be abated; provided, however, if Tenant continues to occupy any portion of the Premises, or reoccupies and conducts its business from any portion of the Premises, during such period, the

19

Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date such business operations commence. Such abatement shall commence as of the first day after the expiration of the “Interruption Period” and terminate upon the cessation of such Adverse Condition. As used herein, the term “Interruption Period” shall mean seven (7) consecutive business days after written notice thereof to Landlord, or such shorter period as applicable under the coverage which is or would be covered by rental abatement insurance required to be carried by Landlord.

19. Alterations.

     19.1. Tenant shall make no alterations, additions or improvements in or to the Property or engage in any construction, demolition, reconstruction, renovation, or other work of any kind in, at, or serving the Premises (“Alterations”) without Landlord’s prior written approval, which approval Landlord may withhold in its sole and absolute discretion; provided, however, that Landlord’s approval shall not be unreasonably withheld, conditioned or delayed in connection with any Alteration that does none of the following (i) adversely affects the exterior appearance of a Building or the Premises, (ii) adversely affects the structural aspects of a Building, including, without limitation, the roof, foundation, load bearing walls and structural elements of a Building or the Premises, (iii) adversely affects any base-building system or equipment, including, without limitation, the base building HVAC, mechanical, electrical, plumbing or life safety systems; (iv) creates a foreseeable risk of violating any Applicable Law or increasing insurance premiums; (v) violates any recorded document affecting the Property; (vi) causes a Building to be inconsistent with the quality and scope of a class “A” office buildings in the vicinity of the Buildings; (vii) involves a use of the Premises that is inconsistent with the current use of the Premises; nor (viii) in Landlord’s reasonable judgment, reduces the quality or value of a Building or the Property (each, a “Design Problem”). In seeking Landlord’s approval, Tenant shall provide Landlord, at least ten (10) business days in advance of any proposed construction, with plans, specifications, bid proposals, work contracts, requests for laydown areas and such other information concerning the nature and cost of the Alterations as Landlord may reasonably request.

     19.2. Notwithstanding the provisions of Section 19.1, Tenant may make non-structural Alterations to the Premises (“Acceptable Changes”) upon at least ten (10) business days prior written notice to Landlord but without Landlord’s prior consent provided (a) the Acceptable Changes do not involve Design Problems; and (b) the cost of such Acceptable Changes do not exceed Fifty Thousand Dollars ($50,000) per occurrence or an aggregate amount of One Hundred Thousand Dollars ($100,000) in any twelve (12) month period.

     19.3. All Alterations made by Tenant shall be: (a) performed in a good and workmanlike manner and in conformance with any and all Applicable Laws and CC&Rs; and (b) shall be made only by a licensed, bonded contractor and such architects, suppliers and mechanics approved in advance by Landlord (which shall not be unreasonably withheld, conditioned or delayed); provided, however, that such contractor need not be bonded or approved and such architects, suppliers and mechanics need not be approved by Landlord in connection with Acceptable Changes.

     19.4. Tenant shall not construct or permit to be constructed partitions or other obstructions that will interfere with free access to mechanical installation or service facilities of the Buildings, or interfere with the moving of Landlord’s equipment to or from the enclosures containing such installations or facilities.

     19.5. Tenant shall accomplish any work performed on the Property in such a manner as to permit any fire sprinkler system and fire water supply lines to remain fully operable at all times.

     19.6. Tenant covenants and agrees that all work done by Tenant or Tenant’s contractors shall be performed in full compliance with Applicable Laws. Within thirty (30) days after completion of any Alterations, Tenant shall provide Landlord with complete “as-built” drawing print sets and electronic CADD files on disc (or files in such other current format in common use as Landlord reasonably approves or requires) showing any changes in the Property (but only if drawings and plans were required by this Lease or were prepared in connection with any such Alterations).

20

     19.7. Before commencing any work, Tenant shall give Landlord at least ten (10) business days’ prior written notice of the proposed commencement of such work.

     19.8. Except for those items listed on Exhibit G, all Alterations, attached equipment, decorations, fixtures, trade fixtures, additions and improvements, subject to Section 19.8, attached to or built into the Property, made by either of the Parties, including, without limitation, all floor and wall coverings, built-in cabinet work and paneling, sinks and related plumbing fixtures, laboratory benches, exterior venting fume hoods and walk-in freezers and refrigerators, ductwork, conduits, electrical panels and circuits shall (unless, prior to such construction or installation, Landlord elects otherwise) become the property of Landlord upon the expiration or earlier termination of the Term, and shall remain upon and be surrendered with the Property as a part thereof. The Property shall at all times remain the property of Landlord and shall be surrendered to Landlord upon the expiration or earlier termination of this Lease. Except for those items on Exhibit G, all trade fixtures, Tenant Improvements, Alterations and Signage installed by or under Tenant shall be the property of Landlord. Notwithstanding the foregoing, at any time during the Term, subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, Tenant shall have the right to update Exhibit G.

     19.9. Tenant shall repair any damage to the Property caused by Tenant’s removal of any property from the Property. During any such restoration period, Tenant shall pay Rent to Landlord as provided herein as if the affected portion of the Premises were otherwise occupied by Tenant. The provisions of this Section shall survive the expiration or earlier termination of this Lease.

     19.10. Except as to those items listed on Exhibit G attached hereto, all business and trade fixtures, machinery and equipment, built-in furniture and cabinets, together with all additions and accessories thereto, attached to or built into the Property shall be and remain the property of Landlord and shall not be moved by Tenant at any time during the Term. If Tenant shall fail to remove any of its effects from the Property within ten (10) days after the termination of this Lease, then Landlord may, at its option, remove the same in any manner that Landlord shall choose and store said effects without liability to Tenant for loss thereof or damage thereto, and Tenant shall pay Landlord, upon demand, any actual, documented and reasonable costs and expenses incurred due to such removal and storage or Landlord may, at its sole option and upon notice to Tenant, sell such property or any portion thereof at private sale and without legal process for such price as Landlord may obtain and apply the proceeds of such sale against any (a) amounts due by Tenant to Landlord under this Lease and (b) any actual and documented expenses incident to the removal, storage and sale of said personal property.

     19.11. Notwithstanding any other provision of this Article 19 to the contrary, in no event shall Tenant remove any improvement from the Property as to which Landlord contributed payment, including, without limitation, the Tenant Improvements made pursuant to the Work Letter without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion.

     19.12. Tenant shall pay to Landlord the Construction Management Fee on the Tenant Improvements. In addition, Tenant shall pay to Landlord an amount equal to one and one-half percent (1.5%) of the cost to Tenant of all Alterations (other than Tenant Improvements) installed by Tenant or its contractors or agents to cover Landlord’s overhead and expenses for plan review, coordination, scheduling and supervision thereof but only for those Alterations requiring Landlord’s consent. For purposes of payment of such sum, Tenant shall submit to Landlord copies of all bills, invoices and statements covering the costs of such charges, accompanied by payment to Landlord of the fee set forth in this Section. Tenant shall reimburse Landlord for any extra expenses incurred by Landlord by reason of faulty work done by Tenant or its contractors.

     19.13. Upon Landlord’s written request, within sixty (60) days after final completion of any Alterations performed by Tenant with respect to the Property, Tenant shall submit to Landlord documentation showing the amounts expended by Tenant with respect to such Alterations, together with supporting documentation reasonably acceptable to Landlord.

21

     19.14. Tenant shall require its contractors and subcontractors performing work on the Property to name Landlord and its affiliates and lenders as additional insureds on their respective insurance policies.

20. Repairs and Maintenance.

     20.1. Subject to Landlord’s obligations hereunder, Tenant, at its sole cost and expense, shall maintain and keep the Property (other than the Diversified Space), all improvements thereon, and all appurtenances thereto, including but not limited to sidewalks, parking areas, curbs, roads, driveways, lighting standards, landscaping, sewers, water, gas and electrical distribution systems and facilities, drainage facilities, and all signs, both illuminated and non-illuminated that are now or hereafter on the Property, in good condition and in a manner consistent with the Permitted Use. Tenant shall make all repairs, replacements and improvements, including, without limitation, all HVAC, plumbing and electrical repairs, replacements and improvements required, and shall keep the same free and clear from all rubbish and debris, excluding, however, the foundation, slab, structural portions of the walls and roof (not including the membrane), and structural steel aspects of the Buildings. All repairs made by Tenant shall be at least equal in quality to the original work, and shall be made only by a licensed, bonded contractor approved in advance by Landlord (which shall not be unreasonably withheld, conditioned or delayed); provided, however, that such contractor need not be bonded or approved by Landlord if the non-structural alterations, repairs, additions or improvements to be performed do not exceed Fifty Thousand Dollars ($50,000) per occurrence or an aggregate amount of One Hundred Thousand Dollars ($100,000) in any twelve (12) month period. Tenant shall not take or omit to take any action, the taking or omission of which shall cause waste, damage or injury to the Property. Tenant shall indemnify, defend (by legal counsel acceptable to Landlord) and hold harmless Landlord from and against any and all Claims (as defined below) arising out of the failure of Tenant or Tenant’s Agents to perform the covenants contained in this Section. “Tenant’s Agents” shall be defined to include Tenant’s officers, employees, agents, contractors, invitees, customers and subcontractors. For the avoidance of doubt, as used in this Article 20 and in Section 11.1, the Diversified Space shall exclude all building systems within the Diversified Space and any demising, exterior or load bearing walls (other than the interior surface of such walls within the Diversified Space).

     20.2. Tenant shall maintain the lines designating the parking spaces in good condition and paint the same as often as may be necessary, so that they are easily discernable at all times; resurface the parking areas as necessary to maintain them in good condition; paint any exterior portions of the Buildings as necessary to maintain them in good condition; maintain the roof and landscaping in good condition; maintain sightly screens, barricades or enclosures around any waste or storage areas; and take all reasonable precautions to insure that the drainage facilities of the roof are not clogged and are in good and operable condition at all times

     20.3. There shall be no abatement of Rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the Tenant’s making of any repairs, alterations or improvements in or to any portion of the Property, or in or to improvements, fixtures, equipment and personal property therein (unless the necessity for any of the same is due to Landlord’s gross negligence or willful misconduct).

     20.4. During the Term, Landlord shall, at Landlord’s sole cost and expense, be responsible for any and all repairs and replacements to the foundation, slab, structural portions of the walls and roof (not including the membrane), and structural steel aspects of the Buildings only. Notwithstanding the foregoing, Tenant shall be responsible for, and shall pay, all costs and expenses of such repair and replacement if such repair or replacement results from anything done by Tenant or Tenant’s Agents or any breach by Tenant under this Lease. For purposes of clarity, except as provided in the preceding sentence, Landlord shall not be responsible for any repairs or replacements to the roof, the exterior walls or any other portions of the Property. Except for the foregoing and except as otherwise provided in this Lease, Landlord shall not be required to maintain or make any repairs or replacements of any nature or description whatsoever to the Property unless the necessity for such repairs or replacements is due to Landlord’s gross negligence or willful misconduct. Except as otherwise provided in this Lease, Tenant hereby expressly waives the right to make repairs at the expense of Landlord as provided for in any Applicable Laws in effect at the time of execution of this Lease, or in any other Applicable Laws that may hereafter be enacted, and waives its rights under Applicable Laws relating to a landlord’s duty to maintain its premises in a tenantable condition. Notwithstanding the

22

foregoing, if Tenant shall fail, where such failure shall continue for a period of ten (10) days after written notice thereof from Landlord to Tenant, to maintain or to commence and thereafter to proceed with diligence to make any repair required of it pursuant to the terms of this Lease, Landlord, without being under any obligation to do so and without thereby waiving such default by Tenant, may so maintain or make such repair and may charge Tenant for the actual and documented costs thereof. Any expense reasonably incurred by Landlord in connection with the making of such repairs may be billed by Landlord to Tenant monthly or, at Landlord’s option, immediately, and shall be due and payable within thirty (30) days after such billing.

     20.5. Landlord and Landlord’s agents shall have the right to enter upon the Property or any portion thereof in accordance with the terms and conditions of Section 34.2, for the purposes of performing any repairs or maintenance Landlord is permitted or required to make pursuant to this Lease, and of ascertaining the condition of the Property or whether Tenant is observing and performing Tenant’s obligations hereunder, all without unreasonable interference from Tenant or Tenant’s Agents.

     20.6. Tenant shall, upon the expiration or sooner termination of the Term, surrender the Property (other than the Diversified Space) to Landlord in as good of a condition as when received, ordinary wear and tear and damage by casualty excepted. Landlord shall have no obligation to alter, remodel, improve, repair, decorate or paint the Property (other than the Diversified Space) or any part thereof, other than pursuant to the terms and provisions of this Lease.

     20.7. Tenant shall, at its sole cost and expense, perform the maintenance and repair obligations of the Parcel 3 Owner (as defined in the REA) pursuant to, and in accordance with, Section 4.1 of the REA.

     20.8. Landlord shall not be liable for any failure to make any repairs or to perform any maintenance that is an obligation of Landlord unless such failure shall persist for an unreasonable time after Tenant provides Landlord with written notice of the need of such repairs or maintenance. Notwithstanding any provision in this Lease to the contrary, if Tenant provides notice to Landlord of an event or circumstance which requires the action of Landlord with respect to the provision of repairs as set forth in Section 20.4 of this Lease, and Landlord fails to provide such action as required by the terms of this Lease within thirty (30) days after the date of such notice from Tenant (or if such repair is reasonably expected to require longer than thirty (30) days to complete, if Landlord shall fail to commence in a meaningful way such repair within said thirty (30) day period and diligently prosecutes such repair to completion), then Tenant may provide Landlord with a second written notice stating in bold and all caps 12 point font that “Landlord’s failure to commence repair of the damage described below within ten (10) business days after Landlord’s receipt of this second notice shall entitle Tenant to repair such damage.” If Landlord does not commence in a meaningful way such repair within such ten (10) business day period, then Tenant shall have the right to take such action, and if such action was required under the terms of this Lease to be taken by Landlord, then Tenant shall be entitled to reimbursement by Landlord of Tenant’s reasonable actual and documented costs and expenses in taking such action. Notwithstanding the foregoing, in case of an emergency (where there is an imminent threat of injury to persons or damage to property), Tenant shall only be required to provide Landlord five (5) business days notice of the need to make such repairs stating in bold and all caps 12 point font that “EMERGENCY: Landlord’s failure to commence its repairs of such damage within five (5) business days after Landlord’s receipt of this notice shall entitle Tenant to repair such damage,” and if Landlord does not commence in a meaningful way such repair within such five (5) business day period, then Tenant shall have the right to take such action. In the event Tenant takes such action, and such work will affect the building systems and equipment, structural integrity of the Buildings or exterior appearance of the Buildings, Tenant shall use only those contractors used by Landlord in connection with the Landlord’s Construction Work for such work unless such contractors are unwilling or unable to perform such work or their pricing is unreasonable, in which event Tenant may utilize the services of any other qualified contractor which normally and regularly performs similar work in comparable first-class, institutional quality, office buildings in the San Diego, California area whose pricing is reasonable. If Tenant is entitled to reimbursement by Landlord of Tenant’s reasonable actual and documented costs and expenses in taking any action pursuant to this Section 20.8, Tenant shall so notify Landlord in writing (the “Reimbursement Notice”), which Reimbursement Notice shall specify in detail such costs and expenses. Within thirty (30) days after Landlord’s receipt of a Reimbursement Notice, Landlord shall pay to Tenant any undisputed portion of such costs and

23

expenses and shall notify Tenant in writing of those costs and expenses specified by Tenant in the Reimbursement Notice which Landlord disputes (the “Disputed Amounts”) and the reasons for such dispute. Any amounts which are not so identified by Landlord as Disputed Amounts within said thirty (30) day period shall be considered to be undisputed. To the extent Landlord fails to reimburse Tenant for the actual and documented costs and expenses specified in the Reimbursement Notice within thirty (30) days after demand therefor, Tenant shall be entitled to offset the sum of the amount of any undisputed portion of such costs and expenses against Basic Annual Rent payable by Tenant under this Lease together with interest at the interest rate of eight percent (8%) per annum from the date of expiration of said thirty (30) day period until the earlier of (a) the date that Landlord reimburses Tenant such amount and (b) the date of offset (up to a maximum offset each month of fifteen percent (15%) of the Basic Annual Rent payable for the Premises) until the full pre-judgment offset amount (plus such interest) has been so offset. If Tenant obtains a final judgment against Landlord for the Disputed Amount and if Landlord fails to pay such judgment within thirty (30) days after the date such judgment is rendered, Tenant shall be entitled to offset such judgment against Basic Annual Rent payable by Tenant under this Lease together with interest at the interest rate of eight percent (8%) per annum from the date Landlord failed to timely reimburse Tenant for such costs and expenses until the earlier of (x) the date that Landlord has reimburses Tenant such amount and (y) the date of offset (up to a maximum offset each month of fifteen percent (15%) of the Basic Annual Rent payable for the Premises) until the full amount of such judgment (plus such interest) has been so offset. If Landlord obtains a final judgment against Tenant for the Disputed Amount, Tenant shall pay to Landlord such judgment within thirty (30) days after the date such judgment is rendered.

     20.9. This Article 20 relates to repairs and maintenance arising in the ordinary course of operation of the Property (other than the Diversified Space) and any related facilities. In the event of fire, earthquake, flood, vandalism, war, terrorism, natural disaster or similar cause of damage or destruction, Article 24 shall apply in lieu of this Article 20.

     20.10. Notwithstanding anything above to the contrary, if during the Term, any portion of the Property which is Tenant’s responsibility hereunder to repair cannot be repaired other than at a cost which is in excess of fifty percent (50%) of the cost of replacing such item(s), then such item(s) shall be replaced by Tenant (subject to Landlord’s prior approval of the plans and specifications and the cost of any such replacement), and Landlord shall reimburse Tenant a prorata share of the cost thereof based upon a fraction, the numerator of which is the number of months of the useful life of such replacement item beyond the expiration of the Term (including any Extended Term, if applicable), and the denominator of which is the total number of months of the useful life of such replacement (as such useful life is specified pursuant to Federal income tax regulations or guidelines for depreciation thereof); provided, however, for purposes of calculating the useful life of such replacement, the useful life of such replacement shall not exceed seven (7) years from the date that such replacement is made.

21. Liens.

     21.1. Subject to the immediately succeeding sentence, Tenant shall keep the Property free from any liens arising out of work performed, materials furnished or obligations incurred by Tenant. Tenant further covenants and agrees that any mechanic’s lien filed against the Property for work claimed to have been done for, or materials claimed to have been furnished to, shall be discharged or bonded by Tenant within ten (10) days after the filing thereof, at Tenant’s sole cost and expense.

     21.2. Should Tenant fail to discharge or bond against any lien of the nature described in Section 21.1, Landlord may, at Landlord’s election, pay such claim or post a bond or otherwise provide security to eliminate the lien as a claim against title, and Tenant shall immediately reimburse Landlord for the actual, documented and reasonable costs thereof as Additional Rent.

     21.3. In the event that Tenant leases or finances the acquisition of office equipment, furnishings or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business (which Tenant shall have the right to do), Tenant warrants that any Uniform Commercial Code financing statement executed by Tenant shall, upon its face or by Exhibit thereto, indicate that such financing statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Property be furnished on a financing statement without qualifying language as to applicability of the lien only to removable personal property located in an identified suite leased by Tenant. Should any

24

holder of a financing statement executed by Tenant record or place of record a financing statement that appears to constitute a lien against any interest of Landlord, Tenant shall, within ten (10) days after filing such financing statement, cause (a) a copy of the lender security agreement or other documents to which the financing statement pertains to be furnished to Landlord to facilitate Landlord’s ability to demonstrate that the lien of such financing statement is not applicable to Landlord’s interest and (b) Tenant’s lender to amend such financing statement and any other documents of record to clarify that any liens imposed thereby are not applicable to any interest of Landlord in the Property.

22. Indemnification and Exculpation.

     22.1. Subject to Section 22.6 below, Tenant agrees to indemnify, defend and save Landlord harmless from and against any and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages or judgments, and all reasonable expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred in investigating or resisting the same (collectively, “Claims”) arising from injury to or death of any person or damage to any property occurring within or about the Property arising directly or indirectly out of Tenant’s or Tenant’s employees’, agents’ or guests’ use or occupancy of the Property or a breach or default by Tenant in the performance of any of its obligations hereunder, unless caused solely by Landlord’s willful misconduct or gross negligence.

     22.2. Landlord agrees to indemnify, defend and save Tenant harmless from and against any and all Claims arising from injury to or death of any person or damage to any property occurring within or about the Diversified Space that arise directly out of Landlord’s obligations under the Diversified Lease after the Effective Date, unless (a) caused by Tenant’s acts or omissions, or (b) arising from Tenant’s performance, or Tenant’s failure to perform, any of Tenant’s obligations under this Lease.

     22.3. Notwithstanding any provision of Section 22.1 to the contrary, but subject to Section 22.5 below, Landlord shall not be liable to Tenant for, and Tenant assumes all risk of, damage to personal property or scientific research, including, without limitation, loss of records kept by Tenant within the Property and damage or losses caused by fire, electrical malfunction, gas explosion or water damage of any type (including, without limitation, broken water lines, malfunctioning fire sprinkler systems, roof leaks or stoppages of lines), unless any such loss is due to Landlord’s gross negligence, willful misconduct and/or willful disregard of written notice by Tenant of need for a repair that Landlord is responsible to make for an unreasonable period of time. Tenant further waives any claim for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property as described in this Section 22.2.

     22.4. Landlord shall not be liable for any damages arising from any act, omission or neglect of any third party other than the gross negligence or willful misconduct of any of Landlord’s officers, employees, agents, general partners, members, and Lenders (“Landlord Parties”).

     22.5. Tenant acknowledges that security devices and services, if any, while intended to deter crime, may not in given instances prevent theft or other criminal acts. Landlord shall not be liable for injuries or losses caused by criminal acts of third parties, and Tenant assumes the risk that any security device or service may malfunction or otherwise be circumvented by a criminal. If Tenant desires protection against such criminal acts, then Tenant shall, at Tenant’s sole cost and expense, obtain appropriate insurance coverage. Notwithstanding any contrary provision of this Lease, neither Landlord nor Tenant shall be liable to the other party for any consequential damages, loss of business or profit for a breach or default under this Lease; provided that this sentence shall not limit Landlord’s damages if, as a result of Tenant’s breach of this Lease: (a) Landlord does not or is unable to lease the Premises to another party, or (b) a third party is unable to occupy the Premises on the date specified in such third party’s lease.

     22.6. Tenant shall not be required to indemnify and hold Landlord harmless from any Claim to any person, property or entity resulting from the grossly negligent acts or omissions or willful misconduct of the Landlord Parties in connection with the Landlord Parties’ activities in, on or about the Property, and Landlord hereby agrees to so indemnify and holds Tenant harmless from any such Claims.

25

     22.7. The provisions of this Article 22 shall survive the expiration or earlier termination of this Lease.

23. Insurance; Waiver of Subrogation.

     23.1. Landlord shall maintain insurance for the Property (including the Diversified Space) in amounts equal to full replacement cost (exclusive of the costs of excavation, foundations and footings, and without reference to depreciation taken by Landlord upon its books or tax returns) or such lesser coverage as Landlord may elect, provided that such coverage shall not be less than ninety percent (90%) of such full replacement cost or the amount of such insurance Landlord’s lender, mortgagee or beneficiary (each, a “Lender”), if any, requires Landlord to maintain, providing protection against any peril generally included within the classification “Fire and Extended Coverage,” together with insurance against sprinkler damage (if applicable), vandalism and malicious mischief. Landlord, subject to availability thereof, shall further insure, if Landlord deems it appropriate, coverage against flood, environmental hazard, earthquake, loss or failure of building equipment, rental loss during the period of repairs or rebuilding, workmen’s compensation insurance and fidelity bonds for employees employed to perform services. Notwithstanding the foregoing, Landlord may, but shall not be deemed required to, provide insurance for any improvements installed by Tenant or that are in addition to the standard improvements customarily furnished by Landlord, without regard to whether or not such are made a part of or are affixed to the Buildings. Any costs incurred by Landlord pursuant to this Section 23.1 shall constitute a portion of Insurance Costs.

     23.2. In addition, Landlord shall carry public liability insurance with a single limit of not less than Ten Million Dollars ($10,000,000) for death or bodily injury, or property damage with respect to the Property (including the Diversified Space). Any costs incurred by Landlord pursuant to this Section 23.2 shall constitute a portion of Insurance Costs.

     23.3. Tenant shall, at its own cost and expense, procure and maintain in effect, beginning on the Commencement Date or the date of occupancy, whichever occurs first, and continuing throughout the Term (and occupancy by Tenant, if any, after termination of this Lease) comprehensive public liability insurance with limits of not less than Five Million Dollars ($5,000,000) per occurrence for death or bodily injury and not less than Two Million Dollars ($2,000,000) for property damage with respect to the Property (including the Diversified Space).

     23.4. Tenant shall, at its sole cost and expense, procure and maintain in effect, beginning on the Commencement Date or the date of occupancy, whichever occurs first, and continuing throughout the Term all insurance required to be maintained by the Parcel 3 Owner (as defined in the REA) in connection with the Parcel 3 Land (as defined in the REA) pursuant to Section 6 of the REA.

     23.5. The insurance required to be purchased and maintained by Tenant pursuant to this Lease shall show, as an additional insured in respect of the Property, Landlord, BioMed Realty, L.P., BioMed Realty Trust, Inc., Tenant, any management company retained by Landlord to manage the Property, any ground lessor and any mortgagee of Landlord required to be named pursuant to its mortgage documents. All public liability and property damage policies shall contain a provision that Landlord, although named as an insured, nevertheless shall be entitled to recovery under said policies for any loss occasioned to it, its servants, agents and employees by reason of the negligence of Tenant. Said insurance shall be with companies having a rating of not less than policyholder rating of A and financial category rating of at least Class XII in “Best’s Insurance Guide.” Tenant shall obtain for Landlord from the insurance companies or cause the insurance companies to furnish certificates of coverage to Landlord. No such policy shall be cancelable or subject to reduction of coverage or other modification or cancellation except after thirty (30) days’ prior written notice to Landlord from the insurer. All such policies shall be written as primary policies, not contributing with and not in excess of the coverage that Landlord may carry. Tenant’s policy may be a “blanket policy” that specifically provides that the amount of insurance shall not be prejudiced by other losses covered by the policy. Tenant shall, at least twenty (20) days prior to the expiration of such policies, furnish Landlord with renewals or binders. Tenant agrees that if Tenant does not take out and maintain such insurance, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and at its cost to be paid by Tenant as Additional Rent.

26

     23.6. Tenant assumes the risk of damage to any fixtures, goods, inventory, merchandise, equipment and leasehold improvements, and Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom, relative to such damage, all as more particularly set forth within this Lease unless caused by Landlord’s gross negligence or willful misconduct. Tenant shall, at Tenant’s sole cost and expense, carry such insurance as Tenant desires for Tenant’s protection with respect to personal property of Tenant or business interruption.

     23.7. In each instance where Tenant’s insurance is to name additional insureds, Tenant shall, upon Landlord’s written request, also designate and furnish certificates evidencing the same to (a) any Lender of Landlord holding a security interest in the Property or any portion thereof, (b) the landlord under any lease whereunder Landlord is a tenant of the real property upon which the Buildings are located if the interest of Landlord is or shall become that of a tenant under a ground lease rather than that of a fee owner, and (c) any management company retained by Landlord to manage the Property.

     23.8. Landlord and Tenant each hereby waive any and all rights of recovery against the other or against the officers, directors, employees, agents and representatives of the other on account of loss or damage occasioned by such waiving party or its property or the property of others under such waiving party’s control, in each case to the extent that such loss or damage is insured against under any fire and extended coverage insurance policy that either Landlord or Tenant may have in force at the time of such loss or damage. Such waivers shall continue so long as their respective insurers so permit. Any termination of such a waiver shall be by written notice to the other party, containing a description of the circumstances hereinafter set forth in this Section 23.8. Landlord and Tenant, upon obtaining the policies of insurance required or permitted under this Lease, shall give notice to the insurance carrier or carriers that the foregoing mutual waiver of subrogation is contained in this Lease. If such policies shall not be obtainable with such waiver or shall be so obtainable only at a premium over that chargeable without such waiver, then the party seeking such policy shall notify the other of such conditions, and the party so notified shall have ten (10) days thereafter to either (a) procure such insurance with companies reasonably satisfactory to the other party or (b) agree to pay such additional premium. If the parties do not accomplish either (a) or (b), then this Section 23.8 shall have no effect during such time as such policies shall not be obtainable or the party in whose favor a waiver of subrogation is desired refuses to pay the additional premium. If such policies shall at any time be unobtainable, but shall be subsequently obtainable, then neither party shall be subsequently liable for a failure to obtain such insurance until a reasonable time after notification thereof by the other party. If the release of either Landlord or Tenant, as set forth in the first sentence of this Section 23.8, shall contravene Applicable Laws, then the liability of the party in question shall be deemed not released but shall be secondary to the other party’s insurer.

24. Damage or Destruction.

     24.1. Subject to Section 24.2, In the event of a partial or complete destruction of the Premises or a Building by fire or other perils, Landlord shall commence and proceed diligently with the work of repair, reconstruction and restoration of the Premises and such Building, as applicable, and this Lease shall continue in full force and effect.

     24.2. Notwithstanding the terms of this Article 24, Landlord may elect not to rebuild and/or restore the Premises and the Buildings and instead terminate this Lease by notifying Tenant in writing of such termination within sixty (60) days after the date of damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Premises or any Building shall be damaged by fire or other casualty or cause or be subject to a condition existing as a result of such a fire or other casualty or cause, and one or more of the following conditions is present: (i) in the reasonable judgment of a contractor selected by Landlord and reasonably approved by Tenant, repairs cannot reasonably be completed within one hundred eighty (180) days of the date of damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Premises or the Buildings, or ground or underlying lessor with respect to the Premises or the Buildings (a) shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt due to an impairment of such holder’s collateral, and the remaining proceeds are insufficient to repair the damage and as a result thereof the deficiency of insurance proceeds exceeds the “Maximum Amount,” as that term is defined below, and Landlord elects not to commence repair to the Premises or the Buildings within one (1) year of such damage or

27

destruction, or (b) shall terminate the ground or underlying lease, as the case may be; (iii) the dollar amount of the damage or condition arising as a result of such damage which is not fully covered by Landlord’s insurance policies (and that would not be fully covered by Landlord’s insurance policies if Landlord had carried the coverage required under this Lease) including any deductible amount, is equal to or greater than Two Hundred and Fifty Thousand Dollars ($250,000) (the “Maximum Amount”), which Maximum Amount shall, as of the date of termination of this Lease, be equal to the product of (a) the Maximum Amount and (b) a fraction, the numerator of which is the number of full months remaining in the Term, or when appropriate the Extended Term then applicable, as of the date of the termination of this Lease, and the denominator of which is 180 (or, if applicable, 60 during an Extended Term) and Landlord elects not to commence repair to the Premises or the Buildings within one (1) year of such damage or destruction; or (iv) the damage occurs during the last twenty-four (24) months of the Term, as such Term may have been extended by Tenant pursuant to this Lease; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs of such damage cannot, in the reasonable opinion of a contractor selected by Landlord and reasonably approved by Tenant, be completed within twelve (12) months after being commenced, Tenant may elect, not later than ten (10) business days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice. At any time, from time to time, after the date occurring thirty (30) days after the date of the damage, but in no event more than once every forty-five (45) days, Tenant may request that Landlord provide Tenant with a certificate from the architect or contractor described above setting forth such architect’s or contractors’ reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within fifteen (15) business days.

     24.3. Landlord shall give written notice to Tenant of its election not to repair, reconstruct or restore the Premises or the Buildings within sixty (60) days following the date of damage or destruction.

     24.4. Upon any termination of this Lease under any of the provisions of this Article 24, the parties shall be released thereby without further obligation to the other from the date possession of the Premises is surrendered to Landlord, except with regard to (a) items occurring prior to the damage or destruction and (b) provisions of this Lease that, by their express terms, survive the expiration or earlier termination hereof.

     24.5. In the event of repair, reconstruction and restoration as provided in this Article 24, all Rent to be paid by Tenant under this Lease shall be abated proportionately based on the extent to which Tenant’s use of the Premises is impaired during the period of such repair, reconstruction or restoration, unless Landlord provides Tenant with other space during the period of repair that, in Tenant’s reasonable discretion, is suitable for the temporary conduct of Tenant’s business; provided, however, that the amount of such abatement shall be reduced by the proceeds of lost rental income insurance actually received by Tenant with respect to the Premises.

     24.6. Notwithstanding anything to the contrary contained in this Article 24, should Landlord be delayed or prevented from completing the repair, reconstruction or restoration of the damage or destruction to the Premises or the Buildings after the occurrence of such damage or destruction by Force Majeure, then the time for Landlord to commence or complete repairs shall be extended on a day-for-day basis.

     24.7. If Landlord is obligated to or elects to repair, reconstruct or restore as herein provided, then Landlord shall be obligated to make such repair, reconstruction or restoration only with regard to those portions of the Premises and the Buildings that were originally provided at Landlord’s expense. The repair, reconstruction or restoration of improvements not originally provided by Landlord or at Landlord’s expense shall be the obligation of Tenant. In the event Tenant has elected to upgrade certain improvements, Landlord shall, upon the need for replacement due to an insured loss, construct the improvements to the standard that existed prior to such damage, unless Tenant again elects to upgrade such improvements and pay any incremental costs related thereto, except to the extent that excess insurance proceeds, if received, are adequate to provide such upgrades, in addition to providing for basic repair, reconstruction and restoration of the Premises and the Buildings.

     24.8. In addition to its termination right in Section 24.2 above, Tenant shall have the right to terminate this Lease if any damage to the Buildings or the Premises: (a) occurs during

28

the last twelve (12) months of the Term of this Lease (including the last twelve (12) months of any Extended Term, if applicable); (b) Tenant is unable to occupy more than twenty-five percent (25%) of the Premises; and (c) in the reasonable judgment of a contractor selected by Landlord and reasonably approved by Tenant, such repairs cannot reasonably be completed within twenty-five percent (25%) of the remaining term of this Lease (including any Extended Term, if applicable).

25. Eminent Domain.

     25.1. Total Taking — Termination. In the event the whole of the Premises, or such part thereof so that reconstruction of the Premises will not result in the Premises being reasonably suitable (as reasonably determined by Landlord and Tenant) for Tenant’s continued occupancy for the uses and purposes permitted by this Lease, shall be taken for any public or quasi-public purpose by any lawful power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to prevent such taking, Tenant or Landlord may terminate this Lease effective as of the date possession is required to be surrendered to said authority.

     25.2. Partial Taking. In the event of a partial taking of the Premises, or of drives, walkways or parking areas serving the Premises for any public or quasi-public purpose by any lawful power or authority by exercise of right of appropriation, condemnation, or eminent domain, or sold to prevent such taking, then, without regard to whether any portion of the Premises occupied by Tenant was so taken, Landlord may elect to terminate this Lease as of such taking if such taking is, in Landlord’s sole opinion, of a material nature such as to make it uneconomical to continue use of the unappropriated portion for purposes of renting office or laboratory space.

     25.3. Tenant shall be entitled to any award that is specifically awarded as compensation for (a) the taking of Tenant’s personal property that was installed at Tenant’s expense and (b) the costs of Tenant moving to a new location. Except as set forth in this Article 25, any award for such taking shall be the property of Landlord.

     25.4. If, upon any taking of the nature described in Sections 25.1 and 25.2, this Lease continues in effect, then (a) Landlord shall promptly proceed to restore the Premises to substantially their same condition prior to such partial taking and this Lease shall, as to the part so taken terminate as of the date that possession of such part of the Premises is taken and the Basic Annual Rent shall be reduced in the same proportion that the floor area of the portion of the Buildings so taken (less any addition thereto by reason of any reconstruction) bears to the original floor area of the Buildings, and (b) in the event of a partial taking of the Diversified Space, (i) Tenant agrees to sublease to Diversified, at no cost to Diversified, up to 6,600 rentable square feet in the Expansion Premises or in the Existing Parcel 1 and Parcel 2 Buildings in accordance with Diversified’s rights under Article 20 of the Diversified Lease, (ii) Tenant shall be entitled to (1) an abatement of fifty percent (50%) of the Expansion Premises Basic Annual Rent for the portion of the Expansion Premises (if any) occupied by Diversified, and (2) an abatement of fifty percent (50%) of the Basic Annual Rent under the Illumina Lease for the portion of the Premises (as defined in the Illumina Lease) (if any) occupied by Diversified, (iii) Landlord shall pay all costs associated with the relocation of Diversified, including, but not limited to, costs of tenant improvements and moving costs, and (iv) Tenant shall not be entitled to an abatement of any of the operating expenses, including Taxes, Insurance Costs, Utility Costs and all other insurance and utility costs and expenses in connection with the portion of the Expansion Premises or the Premises (as defined in the Illumina Lease) occupied by Diversified

26. Defaults and Remedies.

     26.1. Late payment by Tenant to Landlord of Rent and other sums due shall cause Landlord to incur costs not contemplated by this Lease, the exact amount of which shall be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges that may be imposed on Landlord by the terms of any mortgage or trust deed covering the Property. Therefore, if any installment of Rent due from Tenant is not received by Landlord within five (5) days after written notice that such payment is due, Tenant shall pay to Landlord an additional sum of three percent (3%) of the overdue Rent as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the costs that Landlord shall incur by reason of late payment by Tenant. Notwithstanding the foregoing, Landlord shall waive the imposition of such late charge for the

29

first late payment of Rent due hereunder in any calendar year of the Term. In addition to the late charge, Rent not paid when due shall bear interest from the fifth (5th) day after the date due until paid at the lesser of (a) twelve percent (12%) per annum or (b) the maximum rate permitted by Applicable Laws.

     26.2. No payment by Tenant or receipt by Landlord of a lesser amount than the Rent payment herein stipulated shall be deemed to be other than on account of the Rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy provided in this Lease or in equity or at law. If a dispute shall arise as to any amount or sum of money to be paid by Tenant to Landlord hereunder, Tenant shall have the right to make payment “under protest,” such payment shall not be regarded as a voluntary payment, and there shall survive the right on the part of Tenant to institute suit for recovery of the payment paid under protest.

     26.3. If Tenant fails to pay any sum of money (other than Basic Annual Rent) required to be paid by it hereunder, or shall fail to perform any other act on its part to be performed hereunder, Landlord may, without waiving or releasing Tenant from any obligations of Tenant, but shall not be obligated to, make such payment or perform such act; provided that (a) such failure by Tenant continues beyond all applicable notice and cure periods after Landlord delivers notice to Tenant demanding performance by Tenant; or (b) such failure by Tenant reasonably could be expected to result in a violation of Applicable Laws, damage to property or injury to any person, or the cancellation of an insurance policy maintained by Landlord. Notwithstanding the foregoing, in the event of an emergency, Landlord shall have the right to enter the Property and act in accordance with its rights as provided elsewhere in this Lease. Tenant shall pay to Landlord as Additional Rent all sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the annual rate equal to twelve percent (12%) per annum or highest rate permitted by Applicable Laws, whichever is less.

     26.4. The occurrence of any one or more of the following events shall constitute a “Default” hereunder by Tenant:

          26.4.1 The failure by Tenant to make any payment of Rent, as and when due, where such failure shall continue for a period of five (5) days after written notice thereof from Landlord to Tenant;

          26.4.2 The failure by Tenant to observe or perform any obligation or covenant contained herein to be performed by Tenant (other than described in Subsections 26.4.1 and 26.4.2), where such failure shall continue for a period of ten (10) business days after written notice thereof from Landlord to Tenant; provided that, if the nature of Tenant’s default is such that it reasonably requires more than ten (10) business days to cure, Tenant shall not be deemed to be in default if Tenant shall commence such cure within said ten (10) business day period and thereafter diligently prosecute the same to completion;

          26.4.3 Tenant makes an assignment for the benefit of creditors;

          26.4.4 A receiver, trustee or custodian is appointed to or does take title, possession or control of all or substantially all of Tenant’s assets;

          26.4.5 Tenant files a voluntary petition under the United States Bankruptcy Code or any successor statute (the “Bankruptcy Code”) or an order for relief is entered against Tenant pursuant to a voluntary or involuntary proceeding commenced under any chapter of the Bankruptcy Code;

          26.4.6 Any involuntary petition if filed against Tenant under any chapter of the Bankruptcy Code and is not dismissed within sixty (60) days;

          26.4.7 Failure to deliver an estoppel certificate in accordance with Article 31;

          26.4.8 The occurrence of a monetary or material non-monetary default under the Illumina Lease;

30

          26.4.9 The occurrence of any Transfer that is not in compliance with the provisions of Article 27, where such failure shall continue for a period of ten (10) days after written notice thereof from Landlord to Tenant; or

          26.4.10 Tenant’s interest in this Lease is attached, executed upon or otherwise judicially seized and such action is not released within one hundred twenty (120) days of the action.

     No notice given above shall be deemed a forfeiture or a termination of this Lease unless Landlord elects otherwise in such notice.

     26.5. In the event of a Default by Tenant, and at any time thereafter, with or without notice or demand and without limiting Landlord in the exercise of any right or remedy that Landlord may have, Landlord shall be entitled to terminate Tenant’s right to possession of the Premises by any lawful means, in which case this Lease shall terminate and Tenant shall immediately thereafter, surrender possession of the Premises to Landlord. In such event, Landlord shall have the right to re-enter and remove all persons and property, and such property may be removed and stored in a public warehouse or elsewhere at the cost and for the account of Tenant, all without service of notice or resort to legal process and without being deemed guilty of trespass or becoming liable for any loss or damage that may be occasioned thereby. In the event that Landlord shall elect to so terminate this Lease, then Landlord shall be entitled to recover from Tenant all damages incurred by Landlord by reason of Tenant’s default, including, without limitation:

          26.5.1 The worth at the time of award of the unpaid Rent that had been earned at the time of termination; plus

          26.5.2 The worth at the time of award of the amount by which the unpaid Rent that would have been earned during the period commencing with termination of this Lease and ending at the time of award exceeds that portion of the loss of Landlord’s rental income from the Premises that Tenant proves could have been reasonably avoided; plus

          26.5.3 The worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of the loss of Landlord’s rental income from the Premises that Tenant proves could be reasonably avoided; plus

          26.5.4 Any other amount necessary to compensate Landlord for all the detriment caused by Tenant’s failure to perform its obligations under this Lease or that in the ordinary course of things would be likely to result therefrom, including, without limitation, the cost of restoring the Premises to the condition required under the terms of this Lease.

As used in Subsections 26.5.1 and 26.5.2, “worth at the time of award” shall be computed by allowing interest at the rate specified in Section 26.1. As used in Subsection 26.5.3 above, the “worth at the time of the award” shall be computed by taking the present value of such amount, using the discount rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1) percentage point.

     26.6. In addition to any other remedies available to Landlord at law or in equity and under this Lease, Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after Tenant’s Default and abandonment and recover Rent as it becomes due, provided Tenant has the right to sublet or assign, subject only to reasonable limitations). In addition, Landlord shall not be liable in any way whatsoever for its failure or refusal to relet the Premises. For purposes of this Section 26.6, the following acts by Landlord will not constitute the termination of Tenant’s right to possession of the Premises:

     Acts of maintenance or preservation or efforts to relet the Premises, including, but not limited to, alterations, remodeling, redecorating, repairs, replacements and/or painting as Landlord shall consider advisable for the purpose of reletting the Premises or any part thereof, or

     The appointment of a receiver upon the initiative of Landlord to protect Landlord’s interest under this Lease or in the Property.

31

Notwithstanding the foregoing, in the event of a Default by Tenant, Landlord may elect at any time to terminate this Lease and to recover damages to which Landlord is entitled.

     26.7. In the event Landlord elects to terminate this Lease and relet the Premises, Landlord may execute any new lease in its own name. Tenant hereunder shall have no right or authority whatsoever to collect any Rent from such tenant. The proceeds of any such reletting shall be applied as follows:

          26.7.1 First, to the payment of any indebtedness other than Rent due hereunder from Tenant to Landlord, including, without limitation, storage charges or brokerage commissions owing from Tenant to Landlord as the result of such reletting;

          26.7.2 Second, to the payment of the costs and expenses of reletting the Premises, including (a) alterations and repairs that Landlord deems reasonably necessary and advisable and (b) reasonable attorneys’ fees, charges and disbursements incurred by Landlord in connection with the retaking of the Premises and such reletting;

          26.7.3 Third, to the payment of Rent and other charges due and unpaid hereunder; and

          26.7.4 Fourth, to the payment of future Rent and other damages payable by Tenant under this Lease.

     26.8. All of Landlord’s rights, options and remedies hereunder shall be construed and held to be nonexclusive and cumulative. Landlord shall have the right to pursue any one or all of such remedies, or any other remedy or relief that may be provided by Applicable Laws, whether or not stated in this Lease. No waiver of any default of Tenant hereunder shall be implied from any acceptance by Landlord of any Rent or other payments due hereunder or any omission by Landlord to take any action on account of such default if such default persists or is repeated, and no express waiver shall affect defaults other than as specified in said waiver.

     26.9. Landlord’s termination of (a) this Lease or (b) Tenant’s right to possession of the Premises shall not relieve Tenant of any liability to Landlord that has previously accrued or that shall arise based upon events that occurred prior to the later to occur of (i) the date of Lease termination or (ii) the date Tenant surrenders possession of the Premises.

     26.10. In the event of a Default by Tenant hereunder, to the fullest extent required by Applicable Laws (to the extent such Applicable Laws cannot be modified by contract), Landlord shall use commercially reasonable efforts to mitigate its damages.

     26.11. To the extent permitted by Applicable Laws, Tenant waives any and all rights of redemption granted by or under any present or future Applicable Laws if Tenant is evicted or dispossessed for any cause, or if Landlord obtains possession of the Premises due to Tenant’s default hereunder or otherwise.

     26.12. Landlord shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within a reasonable time, but in no event shall such failure continue for more than thirty (30) days after written notice from Tenant specifying the nature of Landlord’s failure; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. In the event of any default by Landlord (beyond the expiration of all applicable notice and cure periods), Tenant may exercise any rights and remedies available at law or in equity.

     26.13. In the event of any default by Landlord, Tenant shall give notice by registered or certified mail to any (a) beneficiary of a deed of trust or (b) mortgagee under a mortgage covering the Property or any portion thereof and to any landlord of any lease of land upon or within which the Premises are located, and shall offer such beneficiary, mortgagee or landlord a reasonable opportunity to cure the default, including time to obtain possession of the Premises by power of sale or a judicial action if such should prove necessary to effect a cure; provided that Landlord shall furnish to Tenant in writing, upon written request by Tenant, the names and addresses of all such persons who are to receive such notices; provided, however, in no event shall such reasonable opportunity to cure exceed an additional sixty (60) days within which to

32

cure or correct such default (or if such default cannot be cured or corrected within that time, then such additional time as may be necessary if such mortgagee has commenced within such sixty (60) day period and is diligently pursuing the remedies or steps necessary to cure or correct such default).

27. Assignment or Subletting.

     27.1. Except as hereinafter expressly permitted, Tenant shall not, either voluntarily or by operation of Applicable Laws, directly or indirectly sell, hypothecate, assign, pledge, encumber or otherwise transfer this Lease, or sublet the Premises or any part hereof (each, a “Transfer”), without Landlord’s prior written consent, which consent Landlord may not unreasonably withhold, condition or delay. Tenant shall have the right to Transfer without Landlord’s prior written consent the Premises or any portion thereof to any person or entity that: (a) directly, or indirectly through one or more intermediaries, (i) controls, is controlled by, or is under common control with Tenant, (ii) acquires all or substantially all of the assets of Tenant, or (iii) is the resulting entity of a merger or consolidation of Tenant with another entity; and (b) has a net worth equal to Two Hundred Million Dollars ($200,000,000) (each, a “Tenant’s Affiliate”), provided (1) Tenant shall notify Landlord in writing at least ten (10) days prior to the effectiveness of such Transfer to Tenant’s Affiliate (an “Exempt Transfer”); and (2) Tenant remains obligated under this Lease. For purposes of Exempt Transfers, “control” requires both (x) owning (directly or indirectly) more than fifty-one percent (51%) of the stock or other equity interests of another person and (y) possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person.

     27.2. In the event Tenant desires to effect a Transfer, then, at least twenty (20) business days but not more than one hundred twenty (120) days prior to the date when Tenant desires the assignment or sublease to be effective (the “Transfer Date”), Tenant shall provide written notice to Landlord (the “Transfer Notice”) containing information (including references) concerning the character of the proposed transferee, assignee or sublessee; the Transfer Date; any ownership or commercial relationship between Tenant and the proposed transferee, assignee or sublessee; and the consideration and all other material terms and conditions of the proposed Transfer; and evidence respecting the relevant business experience and financial responsibility and status of the proposed transferee, assignee or sublessee, all in such detail as Landlord shall reasonably require (the “Transfer Information”). Tenant shall also tender to Landlord the actual, documented and reasonable attorneys’ fees and other costs or overhead expenses incurred by Landlord in reviewing Tenant’s request for such Transfer (not to exceed Two Thousand Five Hundred Dollars ($2,500.00) in the aggregate per Transfer request).

     27.3. Landlord, in determining whether consent should be given to a proposed Transfer, may give consideration to (a) the financial strength of such assignee (notwithstanding Tenant remaining liable for Tenant’s performance), and (b) any change in use that such transferee, assignee or sublessee proposes to make in the use of the Premises. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer to a transferee, assignee or sublessee of lacking financial qualifications or seeking a change in the Permitted Use, or jeopardizing directly or indirectly the status of Landlord or any of Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (the “Code”). Notwithstanding anything contained in this Lease to the contrary, (w) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the income or profits derived by the business activities of such occupant, assignee, manager or other transferee; (x) Tenant shall not furnish or render any services to an occupant, assignee, manager or other transferee with respect to whom transfer consideration is required to be paid, or manage or operate the Premises or any capital additions so transferred, with respect to which transfer consideration is being paid; (y) Tenant shall not consummate a Transfer with any person in which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that could cause any portion of the amounts received by Landlord pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or any similar or successor provision thereto or which could cause any other income of Landlord to fail to qualify as income described in Section 856(c)(2) of the Code. Landlord shall respond to Tenant’s proposed Transfer within twenty (20) days after receipt of Tenant’s Transfer request. If Landlord fails to respond within such twenty

33

(20) day period, then Tenant shall provide Landlord with a second written notice stating in bold and all caps 12 point font that “Landlord’s failure to respond to Tenant’s Transfer request within five (5) days after Landlord’s receipt of this second notice shall be deemed approval by Landlord,” and if Landlord does not respond within such five (5) day period, then Landlord shall be deemed to have approved such Transfer request.

     27.4. As conditions precedent to Tenant subleasing the Premises or to Landlord considering a request by Tenant to Tenant’s transfer of rights or sharing of the Premises, Landlord may require any or all of the following:

          27.4.1 Tenant shall remain fully liable under this Lease during the unexpired Term;

          27.4.2 Tenant shall provide Landlord with the Transfer Information;

          27.4.3 If Tenant’s transfer of rights or sharing of the Premises provides for the receipt by, on behalf of or on account of Tenant of any consideration of any kind whatsoever (including, without limitation, a premium rental for a sublease or lump sum payment for an assignment) in excess of the rental and other charges due to Landlord under this Lease, Tenant shall pay fifty percent (50%) of all of such excess to Landlord, after deductions for tenant improvement allowances actually provided by Tenant, alterations (including hard and soft costs), cash and other monetary concessions, marketing expenses, free rent, brokerage commissions and the actual documented and reasonable attorneys fees necessarily incurred in negotiating such sublease or assignment. If said consideration consists of cash paid to Tenant, payment to Landlord shall be made upon receipt by Tenant of such cash payment;

          27.4.4 The proposed transferee, assignee or sublessee shall agree that, in the event Landlord gives such proposed transferee, assignee or sublessee notice that Tenant is in default under this Lease, such proposed transferee, assignee or sublessee shall thereafter make all payments otherwise due Tenant directly to Landlord, which payments shall be received by Landlord without any liability being incurred by Landlord, except to credit such payment against those due by Tenant under this Lease, and any such proposed transferee, assignee or sublessee shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason; provided, however, that in no event shall Landlord or its Lenders, successors or assigns be obligated to accept such attornment;

          27.4.5 Any such consent to Transfer shall be effected on Landlord’s forms, subject to changes by Tenant that are satisfactory to Landlord in its reasonable discretion;

          27.4.6 Tenant shall not then be in default hereunder (beyond the expiration of all applicable notice and cure periods) in any respect;

          27.4.7 Such proposed transferee, assignee or sublessee’s use of the Premises shall not be inconsistent with the Permitted Use;

          27.4.8 Landlord shall not be bound by any provision of any agreement pertaining to the Transfer, except for Landlord’s written consent to the same;

          27.4.9 Tenant shall pay all transfer and other taxes (including interest and penalties) assessed or payable for any Transfer;

          27.4.10 Landlord’s consent (or waiver of its rights) for any Transfer shall not waive Landlord’s right to consent to any later Transfer;

          27.4.11 Tenant shall deliver to Landlord one executed copy of any and all written instruments evidencing the Transfer; and

          27.4.12 A list of Hazardous Materials (as defined in Section 40.6 below), certified by the proposed transferee, assignee or sublessee to be true and correct, that the proposed transferee, assignee or sublessee intends to use or store in the Property. Additionally, Tenant shall deliver to Landlord, on or before the date any proposed transferee, assignee or sublessee takes occupancy of the Premises, all of the items relating to Hazardous Materials of such proposed transferee, assignee or sublessee as described in Section 40.2.

34

     27.5. Any Transfer that is not in compliance with the provisions of this Article 27 shall be void and constitute a “Default” hereunder.

     27.6. The consent by Landlord to a Transfer shall not relieve Tenant or proposed transferee, assignee or sublessee from obtaining Landlord’s consent to any further Transfer, nor shall it release Tenant or any proposed transferee, assignee or sublessee of Tenant from full and primary liability under this Lease.

     27.7. Notwithstanding any Transfer, Tenant shall remain fully and primarily liable for the payment of all Rent and other sums due or to become due hereunder, and for the full performance of all other terms, conditions and covenants to be kept and performed by Tenant. The acceptance of Rent or any other sum due hereunder, or the acceptance of performance of any other term, covenant or condition thereof, from any person or entity other than Tenant shall not be deemed a waiver of any of the provisions of this Lease or a consent to any Transfer.

     27.8. Licenses to Business Affiliates. Notwithstanding any contrary provision of this Article 27, the original Tenant named hereunder (but not any assignee or subtenant) shall have the right, without the receipt of Landlord’s consent, but on prior written notice to Landlord, to license (but not sublease) up to an aggregate of up to ten percent (10%) of the rentable square feet of the Expansion Premises to individuals or entities (each, a “Business Affiliate”), which license to a Business Affiliate shall be on and subject to all of the following conditions: (i) Tenant shall have a direct contractual business relationship (relating to a primary business of Tenant conducted in the Expansion Premises and other than Business Affiliate’s use of the Expansion Premises) with each such Business Affiliate; (ii) each such Business Affiliate shall be of a character and reputation consistent with the quality of the Buildings; (iii) each such license shall clearly specify that it is only a contract right and that the Business Affiliate is not a subtenant and has no interest in real property; (iv) each such Business Affiliate’s use of the Expansion Premises is in a manner consistent with the Permitted Use; (v) no demising walls or separate entrances shall be constructed in the Expansion Premises to accommodate any such license; (vi) the term of such license shall not exceed six (6) months; and (vii) the licensee shall pay no rent or other compensation to Tenant in respect of such license. No such license shall relieve Tenant from any liability under this Lease.

     27.9. If Tenant sublets the Premises or any portion thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and appoints Landlord as assignee and attorney-in-fact for Tenant, and Landlord (or a receiver for Tenant appointed on Landlord’s application) may collect such rent and apply it toward Tenant’s obligations under this Lease; provided that, until the occurrence of a Default (beyond the expiration at all applicable notice and cure periods) by Tenant, Tenant shall have the right to collect such rent.

28. Attorneys’ Fees. If either party commences an action against the other party arising out of or in connection with this Lease, then the substantially prevailing party shall be entitled to have and recover from the other party reasonable attorneys’ fees, charges and disbursements and costs of suit.

29. [Intentionally Omitted].

30. Definition of Landlord. With regard to obligations imposed upon Landlord pursuant to this Lease, the term “Landlord,” as used in this Lease, shall refer only to Landlord or Landlord’s then-current successor-in-interest. In the event of any transfer, assignment or conveyance of Landlord’s interest in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, Landlord herein named (and in case of any subsequent transfers or conveyances, the subsequent Landlord) shall be automatically freed and relieved, from and after the date of such transfer, assignment or conveyance, from all liability for the performance of any covenants or obligations contained in this Lease thereafter to be performed by Landlord and, without further agreement, the transferee, assignee or conveyee of Landlord’s in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, shall be deemed to have assumed and agreed to observe and perform any and all covenants and obligations of Landlord hereunder during the tenure of its interest in this Lease or the Property. Landlord or any subsequent Landlord may transfer its interest in the Property or this Lease without Tenant’s consent.

35

31. Estoppel Certificate. Tenant shall, within fifteen (15) days of receipt of written notice from Landlord, execute, acknowledge and deliver a statement in writing substantially in the form attached to this Lease as Exhibit I, or on any other commercially reasonable form reasonably requested by a proposed Lender or purchaser, (a) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in advance, if any, (b) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (c) setting forth such further information with respect to this Lease or the Property as may be reasonably requested thereon. Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of which the Premises are a part. Tenant’s failure to deliver such statement within such the prescribed time shall, at Landlord’s option, constitute a Default under this Lease, and, in any event, shall be binding upon Tenant that this Lease is in full force and effect and without modification except as may be represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution and that all other statements set forth in such certificate are true and correct. Landlord shall, within fifteen (15) days of receipt of written notice from Tenant but in no event more than once every twelve (12) months, provide to Tenant an estoppel certificate signed by Landlord, (a) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in advance, if any, and (b) acknowledging that there are not, to Landlord’s knowledge, any uncured defaults on the part of Tenant hereunder, or specifying such defaults if any are claimed.

32. Joint and Several Obligations. If more than one person or entity executes this Lease as Tenant, then:

     32.1. Each of them is jointly and severally liable for the keeping, observing and performing of all of the terms, covenants, conditions, provisions and agreements of this Lease to be kept, observed or performed by Tenant; and

     32.2. The term “Tenant” as used in this Lease shall mean and include each of them, jointly and severally. The act of, notice from, notice to, refund to, or signature of any one or more of them with respect to the tenancy under this Lease, including, without limitation, any renewal, extension, expiration, termination or modification of this Lease, shall be binding upon each and all of the persons executing this Lease as Tenant with the same force and effect as if each and all of them had so acted, so given or received such notice or refund, or so signed.

33. Limitation of Landlord’s Liability.

     33.1. If Landlord is in default under this Lease and, as a consequence, Tenant recovers a monetary judgment against Landlord, the judgment shall be satisfied only out of (a) the proceeds of sale received on execution of the judgment and levy against the right, title and interest of Landlord in the Property, (b) rent or other income from such real property receivable by Landlord, (c) the consideration received by Landlord from the sale, financing, refinancing or other disposition of all or any part of Landlord’s right, title or interest in the Property and (d) any casualty insurance proceeds which Landlord receives for damage to the Property.

     33.2. Landlord shall not be personally liable for any deficiency under this Lease. If Landlord is a partnership or joint venture, then the partners of such partnership shall not be personally liable for Landlord’s obligations under this Lease, and no partner of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any partner of Landlord except as may be necessary to secure jurisdiction of the partnership or joint venture. If Landlord is a corporation, then the shareholders, directors, officers, employees and agents of such corporation shall not be personally liable for Landlord’s obligations under this Lease, and no shareholder, director, officer, employee or agent of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any shareholder, director, officer, employee or agent of Landlord. If Landlord is a limited liability company, then the members of such limited liability company shall not be personally liable for Landlord’s obligations under this Lease, and no member of Landlord shall be sued or named as a party in any suit or action, and service of process shall not be made against any member of Landlord except as may be necessary to secure jurisdiction of the limited liability company. No partner, shareholder, director, employee, member or agent of Landlord shall be required to

36

answer or otherwise plead to any service of process, and no judgment shall be taken or writ of execution levied against any partner, shareholder, director, employee or agent of Landlord.

     33.3. If Tenant is a partnership or joint venture, then the partners of such partnership shall not be personally liable for Tenant’s obligations under this Lease, and no partner of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any partner of Tenant except as may be necessary to secure jurisdiction of the partnership or joint venture. If Tenant is a corporation, then the shareholders, directors, officers, employees and agents of such corporation shall not be personally liable for Tenant’s obligations under this Lease, and no shareholder, director, officer, employee or agent of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any shareholder, director, officer, employee or agent of Tenant. If Tenant is a limited liability company, then the members of such limited liability company shall not be personally liable for Tenant’s obligations under this Lease, and no member of Tenant shall be sued or named as a party in any suit or action, and service of process shall not be made against any member of Tenant except as may be necessary to secure jurisdiction of the limited liability company. No partner, shareholder, director, employee, member or agent of Tenant shall be required to answer or otherwise plead to any service of process, and no judgment shall be taken or writ of execution levied against any partner, shareholder, director, employee or agent of Tenant. Notwithstanding the foregoing, in no event shall the provisions of this Section 33.3 relieve Tenant’s partners, shareholders, directors, employees, members or agents of any personal liability arising out of, or in connection with, such partner’s, shareholder’s, director’s, employee’s, member’s or agent’s gross negligence or willful misconduct.

     33.4. Each of the covenants and agreements of this Article 33 shall be applicable to any covenant or agreement either expressly contained in this Lease or imposed by Applicable Laws and shall survive the expiration or earlier termination of this Lease.

34. Control by Landlord.

     34.1. Subject to Section 34.2, Landlord and Landlord’s offices, employees, lenders, agents, architects, engineering consultants, design team, general contractor, and subcontractors (collectively “Landlord’s Agents”) shall have the right, at any time, to enter the Property and the Buildings to commence and prosecute the construction of Landlord’s Construction Work, the Tenant Improvements and to attend to all other activities related thereto.

     34.2. Landlord and Landlord’s Agents may, at any and all reasonable times during non-business hours (or during business hours if Tenant so requests), and upon twenty-four (24) hours’ prior notice (provided that no time restrictions shall apply or advance notice be required if an emergency necessitates immediate entry), enter the Property to (a) inspect the same and to determine whether Tenant is in compliance with its obligations hereunder, (b) supply any service Landlord is required to provide hereunder, (c) show the Property to prospective purchasers or tenants during the final year of the Term, (d) post notices of nonresponsibility, (e) access the telephone equipment, electrical substation and fire risers, or (f) alter, improve or repair any portion of the Buildings. In connection with any such alteration, improvement or repair as described in Subsection 34.2(f) above, Landlord and Landlord’s Agents may erect in the Property scaffolding and other structures reasonably required for the alteration, improvement or repair work to be performed. Subject to Section 18.5 above, in no event shall Tenant’s Rent abate as a result of Landlord’s activities pursuant to this Section 34.1; provided, however, that all such activities shall be conducted in such a manner so as to cause as little interference to Tenant as is reasonably possible. Landlord shall at all times retain a key with which to unlock all of the doors in the Premises. If an emergency (where there is an imminent threat to persons or property) necessitates immediate access to the Premises, Landlord may use whatever force is necessary to enter the Premises, and any such entry to the Premises shall not constitute a forcible or unlawful entry to the Premises, a detainer of the Premises, or an eviction of Tenant from the Premises or any portion thereof.

35. Quiet Enjoyment. So long as Tenant is not in default under this Lease or as otherwise permitted by this Lease, Landlord or anyone acting through or under Landlord shall not disturb Tenant’s occupancy of the Premises. Notwithstanding the foregoing, to the extent that Landlord uses commercially reasonable efforts to minimize any interference with the construction of the Expansion Building may have on Tenant’s use and quiet enjoyment of the Diversified Building Premises for Tenant’s normal business operations, Tenant hereby (i) accepts any and all

37

inconveniences associated with the construction of the Expansion Building, including, any noise, paint, fumes, dust, debris, obstruction of access (including any obstruction caused by the erection of scaffolding, barricades or other necessary structures on the Property), or any other inconvenience caused by the construction of the Expansion Building, (ii) agrees that the performance of the construction of the Expansion Building shall not constitute a constructive eviction nor shall Tenant be entitled to an abatement of Rent, and (iii) acknowledges and agrees that Landlord shall not, for any reason, be responsible or liable to Tenant for any direct or indirect injury to Tenant or Tenant’s Agents, or interference with Tenant’s business, arising from the construction of the Expansion Building; provided, however, that if Landlord fails to use its commercially reasonable efforts to minimize any interference that the construction of the Expansion Building may have on Tenant’s use of the Diversified Building Premises for Tenant’s normal business operations, such failure results in an Adverse Condition, and as a direct result of such Adverse Condition, Tenant is unable to conduct its business in a reasonable manner in a material portion of the Premises, Tenant shall be entitled to an abatement of rent with respect to such Adverse Condition to the extent Tenant is entitled to an abatement of rent pursuant to the terms and conditions of Section 18.5 above.

36. Subordination and Attornment.

     36.1. Subject to the delivery of the non-disturbance agreements described in this Article 36 as a condition precedent to any such subordination, this Lease shall be subject and subordinate to the lien of any mortgage, deed of trust, or lease in which Landlord is tenant now or hereafter in force against the Property or any portion thereof and to all advances made or hereafter to be made upon the security thereof without the necessity of the execution and delivery of any further instruments on the part of Tenant to effectuate such subordination. In consideration of, and as a condition precedent to, Tenant’s agreement to permit its interest pursuant to this Lease to be subordinated to any particular future ground or underlying lease of the Buildings or the Property or to the lien of any mortgage or trust deed, hereafter enforced against the Buildings or the Property and to any renewals, extensions, modifications, consolidations and replacements thereof, Landlord shall deliver to Tenant a non-disturbance agreement on (a) the form of Exhibit M attached hereto, (b) a commercially reasonable form of non-disturbance agreements of the lessor under such ground lease or underlying lease or the holder of such mortgage or trust deed, or (c) another commercially reasonable form. Landlord’s delivery to Tenant of non-disturbance agreement(s) in favor of Tenant from any ground lessors, mortgage holders or lien holders of Landlord who later came into existence at any time prior to the expiration of the Term shall be in consideration of, and a condition precedent to, Tenant’s agreement to be bound by the terms of this Article 36. Tenant shall be entitled, at Tenant’s sole cost and expense, to record any such non-disturbance agreement promptly after full execution and delivery of such agreement.

     36.2. Notwithstanding the foregoing, Tenant shall execute and deliver upon demand such further commercially reasonable instrument or instruments evidencing such subordination of this Lease to the lien of any such mortgage or mortgages or deeds of trust or lease in which Landlord is tenant as may be required by Landlord. However, if any such mortgagee, beneficiary or Landlord under lease wherein Landlord is tenant so elects, this Lease shall be deemed prior in lien to any such lease, mortgage, or deed of trust upon or including the Property regardless of date and Tenant shall execute a statement in writing to such effect at Landlord’s request.

     36.3. Upon written request of Landlord and opportunity for Tenant to review, Tenant agrees to execute any Lease amendments not materially altering the terms of this Lease, if required by a mortgagee or beneficiary of a deed of trust encumbering real property of which the Premises constitute a part incident to the financing of the real property of which the Premises constitute a part. Any change affecting the amount or timing of the consideration to be paid by Tenant or modifying the term of this Lease shall be deemed as materially altering the terms hereof.

     36.4. Subject to Section 36.1, in the event any proceedings are brought for foreclosure, or in the event of the exercise of the power of sale under any mortgage or deed of trust made by Landlord covering the Property, Tenant shall at the election of the purchaser at such foreclosure or sale attorn to the purchaser upon any such foreclosure or sale and recognize such purchaser as Landlord under this Lease.

38

37. Surrender.

     37.1. No surrender of possession of any part of the Property shall release Tenant from any of its obligations hereunder, unless such surrender is accepted in writing by Landlord.

     37.2. The voluntary or other surrender of this Lease by Tenant shall not effect a merger with Landlord’s fee title or leasehold interest in the Property or any portion thereof, unless Landlord consents in writing, and shall, at Landlord’s option, operate as an assignment to Landlord of any or all subleases.

     37.3. The voluntary or other surrender of any ground or other underlying lease that now exists or may hereafter be executed affecting the Property or any portion thereof, or a mutual cancellation thereof or of Landlord’s interest therein by Landlord and its lessor shall not effect a merger with Landlord’s fee title or leasehold interest in the Property and shall, at the option of the successor to Landlord’s interest in the Property or any portion thereof operate as an assignment of this Lease.

     37.4. In the event Tenant has performed any Alterations in accordance with this Lease, upon surrender of the Premises, Tenant shall reimburse Landlord for any extra costs and expenses incurred by Landlord by reason of any delays in re-leasing the Premises caused by Tenant’s removal of such Alterations.

38. Waiver and Modification No provision of this Lease may be modified, amended or supplemented except by an agreement in writing signed by Landlord and Tenant. The waiver by Landlord of any breach by Tenant of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition herein contained. The waiver by Tenant of any breach by Landlord of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition herein contained.

39. Waiver of Jury Trial and Counterclaims. To the extent allowed under Applicable Laws, the parties waive trial by jury in any action, proceeding or counterclaim brought by the other party hereto related to matters arising out of or in any way connected with this Lease; the relationship between Landlord and Tenant; Tenant’s use or occupancy of the Property; or any claim of injury or damage related to this Lease or the Property.

40. Hazardous Materials.

     40.1. After the Execution Date, Tenant shall not cause or permit any Hazardous Materials (as hereinafter defined) to be brought upon, kept or used in or about the Property in violation of Applicable Laws by Tenant or Tenant’s Agents. If Tenant breaches such obligation, or if the presence of Hazardous Materials brought upon, kept or used in or about the Property by Tenant or Tenant’s Agents results in contamination of the Property or any adjacent property, or if contamination of the Property or any adjacent property by Hazardous Materials otherwise occurs during the term of this Lease or any extension or renewal hereof or holding over hereunder (other than in connection with substances that migrated to the Property from any adjoining property, except in the event Tenant is aware of such contamination and neither remedies such contamination nor promptly notifies Landlord of the existence of such contamination), then Tenant shall indemnify, save, defend and hold Landlord, its agents and contractors harmless from and against any and all claims, judgments, damages, penalties, fines, costs, liabilities and losses (including, without limitation, diminution in value of the Property or any portion thereof; damages for the loss or restriction on use of rentable or usable space or of any amenity of the Property; damages arising from any adverse impact on marketing of space in the Property; and sums paid in settlement of claims, attorneys’ fees, consultants’ fees and experts’ fees) that arise during or after the Term as a result of such breach or contamination, except to the extent arising solely out of Landlord’s construction of the Landlord’s Construction Work or the Tenant Improvements; provided, however, in no event shall Tenant’s indemnity extend to consequential damages; provided that this sentence shall not limit Landlord’s damages if, as a result of Tenant’s breach of this Lease: (a) Landlord does not or is unable to lease the Premises to another party, or (b) a third party is unable to occupy the Premises on the date specified in such third party’s lease. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or restoration work required by any Governmental Authority because of Hazardous

39

Materials present in the air, soil or groundwater above, on or under the Property. Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about the Property or any adjacent property caused or permitted by Tenant or Tenant’s Agents results in any contamination of the Property or any adjacent property, then Tenant shall promptly take all actions at its sole cost and expense as are necessary to return the Property and any adjacent property to their respective condition existing prior to the time of such contamination; provided that Landlord’s written approval of such action shall first be obtained, which approval Landlord shall not unreasonably withhold; and provided, further, that it shall be reasonable for Landlord to withhold its consent if such actions could have a material adverse long-term or short-term effect on the Property.

     40.2. Landlord acknowledges that it is not the intent of this Article 40 to prohibit Tenant from operating its business as described in Section 2.8 above. Tenant may operate its business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored according to Applicable Laws. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Term Commencement Date a list identifying each type of Hazardous Material to be present on the Property and setting forth any and all governmental approvals or permits required in connection with the presence of such Hazardous Material on the Property (the “Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List on or prior to each annual anniversary of the Term Commencement Date and shall also deliver an updated Hazardous Materials List before any new Hazardous Materials are brought onto the Property. Tenant shall deliver to Landlord true and correct copies of the following documents (hereinafter referred to as the “Documents”) relating to the handling, storage, disposal and emission of Hazardous Materials prior to the Term Commencement Date or, if unavailable at that time, concurrent with the receipt from or submission to any Governmental Authority: permits; approvals; reports and correspondence; storage and management plans; notices of violations of Applicable Laws; plans relating to the installation of any storage tanks to be installed in or under the Property (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion); and all closure plans or any other documents required by any and all Governmental Authorities for any storage tanks installed in, on or under the Property for the closure of any such storage tanks. Tenant shall not be required, however, to provide Landlord with any portion of the Documents containing information of a proprietary nature that, in and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous Materials.

     40.3. At any time, and from time to time, prior to the expiration of the Term, Landlord shall have the right to conduct appropriate tests of the Property to demonstrate that Hazardous Materials are present or that contamination has occurred due to Tenant or Tenant’s agents, employees or invitees. Tenant shall pay all reasonable costs of such tests of the Property if such tests demonstrate that Tenant has breached any provision of this Lease regarding Hazardous Materials or has any clean-up obligations under this Article 40.

     40.4. If underground or other storage tanks storing Hazardous Materials are: (a) located on the Property; (b) hereafter placed on the Property by Tenant or Tenant’s Agents, (c) hereafter used by Tenant or Tenant’s Agents, or (d) placed on the Property by any other party and Tenant is aware that such party placed such underground or other storage tank on the Property, Tenant shall monitor the storage tanks, maintain appropriate records, implement reporting procedures, properly close any underground storage tanks, and take or cause to be taken all other steps necessary or required under the Applicable Laws. Tenant shall pay all reasonable costs of such tests of the Property

     40.5. Tenant’s and Landlord’s obligations under this Article 40 shall survive the expiration or earlier termination of this Lease. During any period of time needed by Tenant or Landlord after the termination of this Lease to complete the removal from the Property of any such Hazardous Materials that Tenant is liable for pursuant to the terms and conditions of this Lease, Tenant shall continue to pay Rent in accordance with this Lease, which Rent shall be prorated daily.

     40.6. As used herein, the term “Hazardous Material” means any hazardous or toxic substance, material or waste that is or becomes regulated by any Governmental Authority.

40

     41.2.

     41.3. This Lease shall be deemed and construed to be an “absolute net lease” and, except as herein expressly provided, Landlord shall receive all payments required to be made by Tenant free from all charges, assessments, impositions, expenses and deductions of any and every kind or nature whatsoever. Landlord shall not be required to furnish any services or facilities or to make any repairs, replacements or alterations of any kind in or on the Property except as specifically provided herein. Tenant shall receive all invoices and bills relative to the Property (including the Diversified Space) and, except as otherwise provided herein, shall pay for all expenses directly to the person or company submitting a bill without first having to forward payment for the expenses to Landlord. Tenant shall at Tenant’s sole cost and expense be responsible for the management of the Property (other than the Diversified Space), shall maintain the landscaping and parking lot, and shall make those additional repairs and alterations required of Tenant hereunder to maintain the Property (other than the Diversified Space) in first class condition.

     41.4. Where applicable in this Lease, the singular includes the plural and the masculine or neuter includes the masculine, feminine and neuter. The Section headings of this Lease are not a part of this Lease and shall have no effect upon the construction or interpretation of any part hereof.

     41.5. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease or otherwise until execution by and delivery to both Landlord and Tenant.

     41.6. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor.

     41.7. Each provision of this Lease performable by Tenant shall be deemed both a covenant and a condition.

     41.8. Whenever consent or approval of either party is required, that party shall not unreasonably withhold such consent or approval, except as may be expressly set forth to the contrary.

     41.9. The terms of this Lease are intended by the parties as a final expression of their agreement with respect to the terms as are included herein, and may not be contradicted by evidence of any prior or contemporaneous agreement.

     41.10. Any provision of this Lease that shall prove to be invalid, void or illegal shall in no way affect, impair or invalidate any other provision hereof, and all other provisions of this Lease shall remain in full force and effect and shall be interpreted as if the invalid, void or illegal provision did not exist.

41

     41.11. Landlord may, but shall not be obligated to, record a short form memorandum hereof without Tenant’s consent. Tenant shall reasonably cooperate with Landlord in such recording. Neither party shall record this Lease. Tenant shall have the right to record a memorandum of this Lease (which Landlord shall execute); provided, however, that Tenant shall be responsible for the cost of recording any memorandum of this Lease, including any transfer or other taxes incurred in connection with said recordation. Landlord shall reasonably cooperate with Tenant in such recording at Tenant’s sole cost and expense.

     41.12. The language in all parts of this Lease shall be in all cases construed as a whole according to its fair meaning and not strictly for or against either Landlord or Tenant.

     41.13. Each of the covenants, conditions and agreements herein contained shall inure to the benefit of and shall apply to and be binding upon the parties hereto and their respective heirs; legatees; devisees; executors; administrators; and permitted successors, assigns, sublessees. Nothing in this Section 41.13 shall in any way alter the provisions of this Lease restricting assignment or subletting.

     41.14. Any notice, consent, demand, bill, statement or other communication required or permitted to be given hereunder shall be in writing and shall be given by personal delivery, overnight delivery with a reputable nationwide overnight delivery service, or certified mail (return receipt requested), and if given by personal delivery, shall be deemed delivered upon receipt; if given by overnight delivery, shall be deemed delivered one (1) day after deposit with a reputable nationwide overnight delivery service; and, if given by certified mail (return receipt requested), shall be deemed delivered three (3) business days after the time the notifying party deposits the notice with the United States Postal Service. Any notices given pursuant to this Lease shall be addressed to Tenant at the Premises, or to Landlord or Tenant at the addresses shown in Sections 2.10 and 2.11, respectively. Either party may, by notice to the other given pursuant to this Section, specify additional or different addresses for notice purposes.

     41.15. This Lease shall be governed by, construed and enforced in accordance with the laws of the State in which the Property is located, without regard to such State’s conflict of law principles.

     41.16. That individual or those individuals signing this Lease guarantee, warrant and represent that said individual or individuals have the power, authority and legal capacity to sign this Lease on behalf of and to bind all entities, corporations, partnerships, limited liability companies, joint venturers or other organizations and entities on whose behalf said individual or individuals have signed.

     41.17. To induce Landlord to enter into this Lease, Tenant agrees that it shall promptly furnish to Landlord, from time to time, upon Landlord’s written request, the most recent audited year-end financial statements reflecting Tenant’s current financial condition. Tenant shall, within ninety (90) days after the end of Tenant’s financial year, furnish Landlord with a certified copy of Tenant’s audited year-end financial statements for the previous year. Tenant represents and warrants that all financial statements, records and information furnished by Tenant to Landlord in connection with this Lease are true, correct and complete in all respects. Notwithstanding the foregoing, the provisions of this Section 41.17 shall not apply to Tenant so long as Tenant is a publicly traded company that is listed on a United States stock exchange.

     41.18. This Lease is subject to any recorded covenants, conditions or restrictions now or hereinafter affecting the Premises or the Property (the “CC&Rs”). Tenant shall comply with all CC&Rs except to the extent any future CC&Rs (a) materially adversely affects Tenant’s use of the Premises for its Permitted Use; or (b) materially increase Tenant’s costs under this Lease.

42. Option to Extend Term. Tenant shall have the option (“Option”) to extend the Term of this Lease as to the entire Premises (and no less than the entire Premises) upon the following terms and conditions. Any extension of the Term pursuant to any Option shall be on all the same terms and conditions as this Lease, except as follows:

     42.1. Tenant shall have three (3) options to extend the Term of this Lease by five (5) years each (each, an “Extended Term”), upon the same terms and conditions as this Lease (except as provided below). Basic Annual Rent for the Diversified Building Premises and the Expansion Premises shall be adjusted on the first (1st) day of each Extended Term and every

42

twenty-four (24) months thereafter in accordance with Article 7. The Basic Annual Rent during each Extended Term shall equal the greater of: (a) the Fair Market Value for the Extended Term; and (b) 102.5% of the then-current Basic Annual Rent at the end of the then-current Term or Extended Term, as applicable. “Fair Market Value” means the then-prevailing average annual rate that comparable landlords have accepted in current transactions from new, non-equity (i.e., not being offered equity in the Buildings), nonrenewal, nonexpansion and nonaffiliated tenants of similar financial strength for comparable space in comparable class “A” office buildings comparably located, with comparable size, quality and floor height in a first class office building, or as appropriate, a laboratory building, taking into consideration all relevant factors, including, without limitation, the proposed lease term, the tenant inducements, allowances or concessions, if any, and excluding specialized tenant improvements or tenant paid improvements for a comparable term, with the determination of Fair Market Value to take into account all relevant factors, including tenant inducements, allowances or concessions, if any, the extent of the services provided or to be provided to the Premises, and contraction and expansion options. In the event the tenant inducements, allowances or concessions granted differ from the terms contained in this Lease, an adjustment to the Fair Market Value shall be made on a basis consistent with the adjustments commonly made in the market for comparable differences and concession packages. If Landlord and Tenant cannot agree on the Fair Market Value for purposes of any Extended Term then they shall engage a mutually agreeable independent third party appraiser, which appraiser shall be a real estate broker with at least ten (10) years’ experience in appraising the rental value of leased commercial premises (for research and development and laboratory uses) in the San Diego, California area (the “Appraiser”). If the parties cannot agree on the Appraiser, each shall within ten (10) days after such impasse appoint an Appraiser (meeting the qualifications set forth above) and, within ten (10) days after the appointment of both such Appraisers, those two Appraisers shall select a third Appraiser meeting the qualifications set forth above. If either party fails to timely appoint an Appraiser, then the Appraiser the other party appoints shall be the sole Appraiser. Within ten (10) days after appointment of all Appraiser(s), Landlord and Tenant shall each simultaneously give the Appraisers (with a copy to the other party) its determination of Fair Market Value, with such supporting data or information as each submitting party determines appropriate. Within ten (10) days after such submissions, the Appraisers shall by majority vote select either Landlord’s or Tenant’s Fair Market Value. The Appraisers may not select or designate any other Fair Market Value. The determination of the Appraiser(s) shall bind the parties

     42.2. The Option is not assignable separate and apart from this Lease.

     42.3. The Option is conditional upon Tenant giving Landlord written notice of its election to exercise an Option at least twelve (12) months prior to the end of the expiration of the initial term of this Lease and, if exercised, the applicable Extended Term. Time shall be of the essence as to Tenant’s exercise of each Option. Tenant assumes full responsibility for maintaining a record of the deadlines to exercise any Option(s). Tenant acknowledges that it would be inequitable to require Landlord to accept any exercise of any Option(s) after the date provided for in this Section.

     42.4. Notwithstanding anything contained in this Article 42, Tenant shall not have the right to exercise an Option:

          42.4.1 During the time commencing from the date Landlord delivers to Tenant a written notice that Tenant is in monetary or material non-monetary default under any provision of this Lease or the Illumina Lease and continuing until Tenant has cured the specified default; or

          42.4.2 At any time after any Default as described in Article 26 of this Lease (provided, however, that, for purposes of this Subsection 42.4(b), Landlord shall not be required to provide Tenant with notice of such Default) and continuing until Tenant cures any such Default, if such Default is susceptible to being cured; or

          42.4.3 In the event that Tenant has defaulted in the performance of its obligations under this Lease three (3) or more times and a service or late charge has become payable under Section 26.1 for each of such defaults during the twelve (12)-month period immediately prior to the date that Tenant intends to exercise an Option, whether or not Tenant has cured such defaults.

43

     42.5. The period of time within which Tenant may exercise an Option shall not be extended or enlarged by reason of Tenant’s inability to exercise such Option because of the provisions of Section 42.4.

43. Tenant’s Authority. Tenant hereby covenants and warrants that (a) Tenant is duly incorporated or otherwise established or formed and validly existing under the laws of its state of incorporation, establishment or formation, (b) Tenant has and is duly qualified to do business in the state in which the Property is located, (c) Tenant has full corporate, partnership, trust, association or other appropriate power and authority to enter into this Lease and to perform all Tenant’s obligations hereunder and (d) each person (and all of the persons if more than one signs) signing this Lease on behalf of Tenant is duly and validly authorized to do so.

45. Confidentiality. Neither party shall disclose any terms or conditions of this Lease (including Rent) or give a copy of this Lease to any third party, and Landlord shall not release to any third party any nonpublic financial information or nonpublic information about Tenant’s ownership structure that Tenant gives Landlord, except (a) if required by Applicable Laws or in any judicial proceeding, provided that the releasing party has given the other party reasonable notice of such requirement, if feasible, (b) to a party’s attorneys, accountants, brokers and other bona fide consultants or advisers, provided such third parties agree to be bound by this Section or (c) to bona fide prospective assignees or subtenants of this Lease, provided they agree in writing to be bound by this Section.

46. Excavation. If any excavation shall be made upon land adjacent to or under the Buildings, or shall be authorized to be made, Tenant shall afford to the person causing or authorized to cause such excavation, license to enter the Property for the purpose of performing such work as said person shall deem necessary or desirable to preserve and protect the Buildings from injury or damage and to support the same by proper foundations, without any claim for damages or liability against Landlord and without, subject to the terms and conditions of this Lease, reducing or otherwise affecting Tenant’s obligations under this Lease.

47. Telecommunications Equipment. At any time during the Term, subject to the terms of this Article 47 and subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld or delayed, Tenant shall have the exclusive right to install, at Tenant’s sole cost and expense, satellite or microwave dishes or other communication equipment (the “Telecommunications Equipment”) upon the roof of the Expansion Building. The physical appearance and the size of the Telecommunications Equipment shall be subject to Landlord’s written approval prior to installation, which approval will not unreasonably be withheld, any covenants, conditions, or restrictions encumbering the Property and, any Applicable Laws. Tenant shall maintain such Telecommunications Equipment in good condition and repair, at Tenant’s sole cost and expense. The cost of the Telecommunications Equipment, including but not limited to the permitting, installation, maintenance and removal thereof shall be at Tenant’s sole cost and expense. If Tenant fails to maintain its Telecommunications Equipment, or if Tenant fails to remove such Telecommunications Equipment upon termination of this Lease, or fails to repair any damage caused by such removal, Landlord may do so at Tenant’s expense. Tenant shall on demand reimburse Landlord for all costs incurred by Landlord to effect such removal, which amounts shall be deemed Additional Rent and shall include without limitation, all sums disbursed, incurred or deposited by Landlord, including Landlord’s costs, expenses and actual attorneys’ fees with interest thereon. Tenant shall indemnify, defend and hold harmless Landlord from and against any loss, cost, claim, lawsuit, liability or expense (including reasonable attorneys’ fees and disbursements) arising directly or indirectly out of Tenant’s failure to perform any of its obligations under this Article 47.

48. Access to Premises. Subject to Section 34.2, Tenant shall be granted access to the Premises (including the parking facilities) twenty-four (24) hours per day, seven (7) days per week, every day of the year.

44

49. Secured Areas. Notwithstanding anything to the contrary set forth in this Lease, Tenant may designate certain areas of the Premises as “Secured Areas” should Tenant require such areas for the purpose of securing certain valuable property or confidential information. Landlord may not enter such Secured Areas except in the case of emergency or in the event of a Landlord inspection, in which case Landlord shall provide Tenant with one (1) business day prior written notice of the specific date and time of such Landlord inspection.

     1.1 Tenant’s Authorized Representative. Tenant designates Jeff Hughson (“Tenant’s Authorized Representative”) as the person authorized to initial all plans, drawings, changes orders and approvals pursuant to this Work Letter. Landlord shall not be obligated to respond to or act upon any such item until such item has been initialed by Tenant’s Authorized Representative. Tenant may change Tenant’s Authorized Representative upon five (5) days’ prior written notice to Landlord.

     1.2 Responsibility Matrix. Landlord and Tenant have approved that certain Responsibility Matrix attached hereto as Exhibit A-1 (the “Responsibility Matrix”). The Responsibility Matrix shall be determinative in allocating work between the Tenant Improvements and the Landlord’s Construction Work.

     1.3 Landlord’s Construction Work. The schedule for the design and development of Landlord’s Construction Work (as defined in the Lease), including, without limitation, the time periods for preparation and review of construction documents, approvals and performance, shall be in accordance with that certain schedule prepared by Landlord and Tenant attached as Exhibit A-2 to this Work Letter (the “Landlord’s Construction Work Schedule”). The Landlord’s Construction Work Schedule shall be subject to adjustment as mutually agreed upon in writing by the parties, or as provided in this Work Letter.

     1.4 Landlord’s Construction Work: Architects and Consultants. The architect, engineering consultants, design team, general contractor and subcontractors responsible for the construction of Landlord’s Work (as defined below) shall be selected by Landlord and approved by Tenant, which approval Tenant shall not unreasonably withhold, condition or delay.

     1.5 Tenant Improvements: Architect. The architect responsible for the preparation of the TI Program and the Schematic TI Plans shall be selected by Tenant and approved by Landlord, which approval Landlord shall not unreasonably withhold, condition or delay. Landlord hereby approves Ferguson Pape Baldwin Architects as Tenant’s architect.

2. Landlord’s Construction Work.

     2.1 Landlord’s Construction Work. Landlord’s Construction Work shall be performed by Landlord at Landlord’s sole cost and expense in accordance with the Approved CW Plans (as defined below), the outline specifications attached hereto as Exhibit B, and the Landlord’s Construction Work Schedule, subject only to changes approved in accordance with Section 2.3.

     2.2 Approved CW Plans. Landlord shall prepare final plans and specifications for Landlord’s Construction Work that are: (a) consistent with and are logical evolutions of the Design Development Drawings dated December 5, 2006 and prepared by Ferguson Pape Baldwin, which have been reasonably approved by Tenant, (b) incorporate CW Permitted Changes, and (c) incorporate any other Landlord-requested (and Tenant approved) CW Changes. As soon as such final plans and specifications (“Final CW Plans”) are completed, Landlord shall deliver the same to Tenant for Tenant’s approval, which approval may be reasonably withheld only if: (i) the Final CW Plans are not consistent with or logical evolutions of the approved Design Development Drawings, (ii) Tenant requests changes to the Final CW Plans in

EXHIBIT J-1

accordance with Section 2.3(a)(i), or (iii) Tenant objects to any Landlord requested CW Change (other than CW Permitted Changes). Such Final CW Plans shall be approved or disapproved by Tenant within seven (7) days after delivery to Tenant. If Tenant fails to respond within such seven (7) days period, then Landlord shall provide Tenant with a second written notice stating that “Tenant’s failure to respond within three (3) days after Landlord’s second notice shall be deemed Tenant’s approval of the Final CW Plans,” and if Tenant does not respond within such three (3) day period, then Tenant shall be deemed to have approved the Final CW Plans. If the Final CW Plans are disapproved by Tenant, Tenant shall notify Landlord in writing of its objections to such Final CW Plans and shall submit any requested CW Changes through a CW Tenant Change Order Request (as defined below), then the parties shall confer and negotiate in good faith to reach agreement on the Final CW Plans. Promptly after the Final CW Plans are approved by Landlord and Tenant, two (2) copies of such Final CW Plans shall be initialed and dated by Landlord and Tenant as soon as approved by Landlord and Tenant, Landlord shall promptly submit such Final CW Plans to all appropriate governmental agencies for approval. The Final CW Plans so approved, and all change orders specifically permitted by the Lease, are referred to herein as the “Approved CW Plans” and shall become part of the Lease as though set forth in full.

     2.3 Changes to Landlord’s Construction Work. Any changes to the Final CW Plans or the Approved CW Plans (each, a “CW Change”) requested by Landlord or Tenant (other than CW Permitted Changes by Landlord) shall be requested and instituted in accordance with the provisions of this Article 2 and shall be subject to the written approval of the other party in accordance with this Work Letter.

          (a) CW Changes Requested by Tenant.

               (i) CW Tenant Change Order Request. Tenant may request CW Changes to the Final CW Plans or the Approved CW Plans by notifying Landlord thereof in writing in substantially the same form as the AIA standard change order form (a “CW Tenant Change Order Request”), which CW Tenant Change Order Request shall detail the nature and extent of any requested CW Changes, including, without limitation, (a) the CW Change, (b) the party required to perform the CW Change, and (c) any modification of the Final CW Plans or the Approved CW Plans, as applicable, and the Landlord’s Construction Work Schedule necessitated by the CW Change. If the nature of a CW Change requires revisions to the Final CW Plans or the Approved CW Plans, as applicable, or the Landlord’s Construction Work Schedule, then Tenant shall be solely responsible for the cost and expense of such revisions. In the event Landlord approves such CW Change, Landlord shall: (1) notify Tenant if it reasonably believes such CW Change could cause a delay in the Landlord’s Construction Work Schedule; and (2) provide Landlord’s reasonable estimate of any additional costs and expenses associated with such CW Change. Tenant shall deposit with Landlord the additional cost and expense payable by Landlord, as reasonably estimated by Landlord, to complete the Construction Work due to a Tenant-requested CW Change within ten (10) days of receiving Landlord’s approval of such CW Change (the “CW Deposit”). In the event such deposit is not sufficient to cover the actual cost of such approved CW Change, Tenant shall reimburse Landlord the difference between the actual cost of such CW Change and the CW Deposit. Tenant shall have the right to apply the Additional Allowance (as defined in the Lease) towards the CW Deposit. CW Tenant Change Order Requests shall be signed by Tenant’s Authorized Representative.

               (ii) Landlord’s Approval of CW Changes. If Landlord does not notify Tenant in writing of Landlord’s decision either to proceed with or abandon Tenant requested CW Change within ten (10) days after receipt of a CW Tenant Change Order Request, then such CW Tenant Change Order Request shall be deemed rejected by Landlord, and Tenant shall not be permitted to alter Landlord’s Construction Work as contemplated by such CW Tenant Change Order Request. Landlord may withhold in it sole and absolute discretion its approval of any CW Tenant Change Order Request; provided, however, Landlord shall not unreasonably withhold its approval to any CW Change requested by Tenant that is a CW Permitted Change or that could not reasonably be expected, as reasonably determined by Landlord, to cause a Design Problem.

          (b) Changes Requested by Landlord.

               (i) CW Landlord Change Order Request. Landlord may request CW Changes to Landlord’s Construction Work by notifying Tenant thereof in writing in substantially the same form as the AIA standard change order form (a “CW Landlord Change Order

EXHIBIT J-2

Request”), which CW Landlord Change Order Request shall detail the nature and extent of any requested CW Changes, including, without limitation, (a) the CW Change, (b) the party required to perform the CW Change, and (c) any modification of the Approved CW Plans and the Landlord’s Construction Work Schedule necessitated by the CW Change.

               (ii) Tenant’s Approval of CW Change. Tenant shall have seven (7) days after receipt of a CW Landlord Change Order Request to notify Landlord in writing of Tenant’s approval or rejection of the Landlord-requested CW Change, which approval shall not be unreasonably withheld, conditioned or delayed. If Tenant fails to respond within such seven (7) days period, then Landlord shall provide Tenant with a second written notice stating that “Tenant’s failure to respond within three (3) days after Landlord’s second notice shall be deemed Tenant’s approval to such CW Landlord Change Order Request,” and if Tenant does not respond within such three (3) day period, then Tenant shall be deemed to have approved such CW Landlord Change Order Request.

          (c) CW Permitted Changes. For purposes of this Work Letter, a “CW Permitted Change” shall mean: (a) minor field changes; (b) changes required by Governmental Authority; (c) any other changes that: (1) do not materially and adversely affect the building structure, roof, or building service equipment to be constructed as part of Landlord’s Construction Work, (2) do not materially change the size, cost, configuration, or overall appearance of the Expansion Building or Landlord’s ability to construct Landlord’s Construction Work or Tenant’s ability to operate its business in the Expansion Building, and (3) will not extend the Scheduled Completion Date of Landlord’s Construction Work (as set forth in the Landlord’s Construction Work Schedule) beyond October 1, 2008; and (d) ordinary development of the Approved CW Plans in a manner not inconsistent with the Approved CW Plans.

3. Tenant Improvements.

     3.1 TI Program. The Tenant Improvements shall be performed by Landlord at Tenant’s sole cost and expense and without cost to Landlord (except for the TI Allowance) and in accordance with the Approved TI Plans (as defined below). On or before April 1, 2007, Tenant shall prepare and submit to Landlord for Landlord’s approval a TI Program for the Tenant Improvements (the “TI Program”). Landlord shall notify Tenant in writing within ten (10) business days after receipt of the TI Program whether Landlord approves or rejects to the TI Program and of the manner, if any, in which the TI Program is objectionable. If Landlord objects to the TI Program, then Tenant shall revise the TI Program and cause Landlord’s permitted objections to be remedied in the revised TI Program. Tenant shall then resubmit the revised Tenant Program to Landlord for approval within ten (10) business days after Tenant receives Landlord’s comments on the TI Program. Landlord shall not unreasonably withhold its approval of any iteration of the TI Program so long as the TI Program does not include any Design Problem and the date when Landlord expects the Tenant Improvements to be Substantially Completed (the “Expected TI Substantial Completion Date”) based thereon is no later than October 1, 2008 (the “Target TI Substantial Completion Date”). Landlord’s approval of or objection to the revised TI Program and Tenant’s correction of the same shall be in accordance with this Section 3.1 until Landlord has approved the TI Program in writing. Any delay in the final approval of the TI Program beyond June 1, 2007 shall be a Tenant Delay except to the extent that Tenant demonstrates that such delay in the approval of the TI Program resulted from Landlord’s failure to comply with the requirements of this Section 3.1. The iteration of the TI Program that is approved by Landlord without objection shall be referred to herein as the “Approved TI Program”.

     3.2 Schematic TI Plans. Within thirty (30) business days after Landlord’s approval of the Approved TI Program, Tenant shall prepare and submit to Landlord for approval schematics covering the Tenant Improvements prepared in conformity with the Approved TI Program (the “Schematic TI Plans”). The Schematic TI Plans shall contain sufficient information and detail to accurately describe the proposed design to Landlord and such other information as Landlord may reasonably request. Tenant shall be solely responsible for ensuring that the Approved TI Program and the Schematic TI Plans satisfy Tenant’s business requirements. Subject to Section 3.4(a)(ii), Landlord shall notify Tenant in writing within ten (10) business days after receipt of the Schematic TI Plans whether Landlord approves or objects to the Schematic TI Plans and of the manner, if any, in which the Schematic TI Plans are objectionable. If Landlord objects to the Schematic TI Plans, then Tenant shall revise the Schematic TI Plans and cause Landlord’s reasonable objections to be remedied in the revised Schematic TI Plans. Tenant shall then

EXHIBIT J-3

resubmit the revised Schematic TI Plans to Landlord for approval within ten (10) business days after Tenant received Landlord’s comments to the Schematic TI Plans. Landlord’s approval of or objection to revised Schematic TI Plans and Tenant’s correction of the same shall be in accordance with this Section 3.2, until Landlord has approved the Schematic TI Plans in writing. Landlord shall not unreasonably withhold its approval of any iteration of the Schematic TI Plans so long as such iteration of such Schematic TI Plans do not include any Design Problem, are consistent with the Approved TI Program and the Expected TI Substantial Completion Date is not later than the Target TI Substantial Completion Date. Any delay in the final approval of the Schematic TI Plans beyond the day that is thirty (30) days after Landlord approves the TI Program shall be a Tenant Delay except to the extent that Tenant demonstrates that such delay in the approval of the Schematic TI Plans resulted from Landlord’s failure to comply with the requirements of this Section 3.2. The iteration of the Schematic TI Plans that is approved by Landlord without objection shall be referred to herein as the “Approved Schematic TI Plans.”

     3.3 Construction TI Plans. Landlord shall prepare final plans and specifications for the Tenant Improvements that: (a) are consistent with and are logical evolutions of the Approved Schematic TI Plans, (b) incorporate TI Permitted Changes, and (c) incorporate any other Landlord-requested (and Tenant approved) TI Changes. As soon as such final plans and specifications (“Construction TI Plans”) are completed, Landlord shall deliver the same to Tenant for Tenant’s approval, which approval may be reasonably withheld only if: (i) the Construction TI Plans are not consistent with or logical evolutions of the Approved Schematic TI Plans, (ii) Tenant intends to request changes to the Construction TI Plans in accordance with Section 3.4(a)(i), or (iii) Tenant objects to any Landlord requested TI Change (other than TI Permitted Changes). Such Construction TI Plans shall be approved or disapproved by Tenant within seven (7) business days after delivery to Tenant. If Tenant fails to notify Landlord of disapproval within such seven (7) days period, then Landlord shall provide Tenant with a second written notice stating that “Tenant’s failure to respond within three (3) days after Landlord’s second notice shall be deemed Tenant’s approval to such Construction TI Plans,” and if Tenant does not respond within such three (3) day period, then Tenant shall be deemed to have approved such Construction TI Plans. If the Construction TI Plans are disapproved by Tenant, Tenant shall notify Landlord in writing of its objections to such Construction TI Plans and shall submit any requested TI Changes through a TI Tenant Change Order Request (as defined below), then the parties shall confer and negotiate in good faith to reach agreement on the Construction TI Plans. Promptly after the Construction TI Plans are approved by Landlord and Tenant, two (2) copies of such Construction TI Plans shall be initialed and dated by Landlord and Tenant as soon as approved by Landlord and Tenant, Landlord shall promptly submit such Construction TI Plans to all appropriate governmental agencies for approval. The Construction TI Plans so approved, and all change orders specifically permitted by the Lease, are referred to herein as the “Approved TI Plans” and shall become part of the Lease as though set forth in full.

     3.4 Changes to Tenant Improvements. Any changes to the Construction TI Plans or the Approved TI Plans (each, a “TI Change”) requested by Landlord or Tenant (other than TI Permitted Changes by Landlord) shall be requested and instituted in accordance with the provisions of this Article 3 and shall be subject to the written approval of the other party in accordance with this Work Letter.

          (a) TI Changes Requested by Tenant.

               (i) TI Tenant Change Order Request. Tenant may request TI Changes after Tenant approves the Construction TI Plans or the Approved TI Plans, as applicable, by notifying Landlord thereof in writing in substantially the same form as the AIA standard change order form (a “TI Tenant Change Order Request”), which TI Tenant Change Order Request shall detail the nature and extent of any requested TI Changes, including, without limitation, (a) the TI Change, (b) the party required to perform the TI Change, and (c) any modification of the Construction TI Plans or the Approved TI Plans, as applicable. If the nature of a TI Change requires revisions to the Construction TI Plans or the Approved TI Plans, as applicable, then Tenant shall be solely responsible for the cost and expense of such revisions. In the event Landlord approves such TI Change, Landlord shall: (1) notify Tenant if it reasonably believes such TI Change could cause a delay in Substantial Completion of the Tenant Improvements; and (2) provide Landlord’s reasonable estimate of any additional costs and expenses associated with such TI Change. Tenant shall reimburse Landlord the additional cost and expense payable by Landlord, as reasonably estimated by Landlord, to complete the Tenant Improvements due to a Tenant-requested TI Change as “Excess Costs” in accordance with Section 4.2.2 of the Lease.

EXHIBIT J-4

               (ii) Landlord’s Approval of TI Changes. All Tenant-requested TI Changes shall be subject to Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed so long as such TI Change would not create a Design Problem and would not delay Substantial Completion of the Tenant Improvements beyond the Target TI Substantial Completion Date. Landlord shall have ten (10) days after receipt of a TI Tenant Change Order Request to notify Tenant in writing of Landlord’s decision either to proceed with or abandon Tenant-requested TI Change. If Landlord does not approve in writing a TI Tenant Change Order Request, then such TI Tenant Change Order Request shall be deemed rejected by Landlord, and Tenant shall not be permitted to alter Tenant Improvements as contemplated by such TI Tenant Change Order Request.

          (b) TI Changes Requested by Landlord.

               (i) TI Landlord Change Order Request. Other than TI Permitted Changes, Landlord may request TI Changes after Tenant approves the Approved TI Plans by notifying Tenant thereof in writing in substantially the same form as the AIA standard change order form (a “TI Landlord Change Order Request”), which TI Landlord Change Order Request shall detail the nature and extent of any requested TI Changes, including, without limitation, (a) the TI Change, (b) the party required to perform the TI Change, and (c) any modification of the Approved TI Plans, or any delay in the Expected TI Substantial Completion Date, necessitated by the TI Change. If the nature of a Landlord requested TI Change requires revisions to the Construction TI Plans or the Approved TI Plans, then Landlord shall be solely responsible for the cost and expense of such revisions (and such cost shall not be deducted from the TI Allowance).

               (ii) Tenant’s Approval of TI Change. Tenant shall have seven (7) days after receipt of a TI Landlord Change Order Request to notify Landlord in writing of Tenant’s approval or rejection of the Landlord-requested TI Change, which approval shall not be unreasonably withheld, conditioned or delayed. If Tenant fails to respond within such seven (7) days period, then Landlord shall provide Tenant with a second written notice stating “that Tenant’s failure to respond within three (3) days after Landlord’s second notice shall be deemed Tenant’s approval to such Landlord-requested TI Change,” and if Tenant does not respond within such three (3) day period, then Tenant shall be deemed to have approved such Landlord-requested TI Change.

          (c) TI Permitted Changes. For purposes of this Work Letter, a “TI Permitted Change” shall mean: (a) minor field changes; (b) changes required by Governmental Authority; (c) any other changes that: (1) do not materially and adversely affect the building structure, roof, or building service equipment to be constructed as part of the Tenant Improvements, (2) do not materially change the size, cost, configuration, or overall appearance of the Tenant Improvements or Tenant’s ability to operate its business in the Expansion Building, and (3) will not extend the Expected TI Substantial Completion Date beyond October 1, 2008; and (d) ordinary development of the Approved TI Plans in a manner not inconsistent with the Approved TI Plans.

     3.5 TI Allowance.

          (a) Application of TI Allowance. Landlord shall contribute the TI Allowance toward the costs and expenses incurred in connection with the performance of the Tenant Improvements, in accordance with Section 4.2 of the Lease. If the entire TI Allowance is not applied toward or reserved for the costs of the Tenant Improvements, Tenant shall not be entitled to a credit of such unused portion of the TI Allowance.

          (b) Approval of Budget for Landlord’s Work. Notwithstanding anything to the contrary set forth elsewhere in this Work Letter or the Lease, Landlord shall not have any obligation to expend any portion of the TI Allowance until Landlord and Tenant shall have approved in writing the budget for the Tenant Improvements (the “Approved Budget”). Prior to Landlord’s and Tenant’s approval of the Approved Budget, Tenant shall pay all of the costs and expenses incurred in connection with Tenant Improvements as they become due. Landlord shall not be obligated to reimburse Tenant for costs or expenses relating to Tenant Improvements that exceed either (a) the amount of the TI Allowance (other than pursuant to Section 4.3 of the Lease pertaining to the Additional Allowance) or (b) the Approved Budget, either on a line item or on

EXHIBIT J-5

an overall basis. Tenant’s payment to Landlord of any such excess costs shall be paid as “Excess Costs” in accordance with Section 4.2.2 of the Lease

          (c) Application of the TI Allowance. Tenant may apply the TI Allowance for the payment of construction and other costs (including, without limitation, standard laboratory improvements; finishes; building fixtures; building permits; and architectural, engineering, design and consulting fees), in each case as reflected in the Approved Budget and the Approved TI Plans. In no event shall the TI Allowance be applied to: (i) the purchase of any furniture, personal property or other non-building system equipment; (ii) the cost of work that is not authorized by the Approved TI Plans or approved in writing by Landlord, (iii) costs resulting from any default by Tenant of its obligations under the Lease, or (iv) costs that are recoverable or reasonably recoverable by Tenant from a third party (e.g., insurers, warrantors, or tortfeasors).

4. Requests for Consent. Except as otherwise provided in this Work Letter, Tenant shall respond to all requests for consents, approvals or directions made by Landlord pursuant to this Work Letter within seven (7) days following Tenant’s receipt of such request. If Tenant fails to respond within such seven (7) days period, then Landlord shall provide Tenant with a second written notice stating that “Tenant’s failure to respond within three (3) days after Landlord’s second notice shall be deemed approval by Tenant,” and if Tenant does not respond within such three (3) day period, then Tenant shall be deemed to have approved such item.

5. Cost Proposal. After the Approved TI Plans are approved by Landlord and Tenant, and the Contractor and subcontractors have been selected, Landlord shall provide Tenant with a cost proposal setting forth the reconciled bids and copies of all sub-bids, which cost proposal shall include, as nearly as possible, the cost of all items to be incurred in connection with the construction of the Tenant Improvements (the “Cost Proposal”). The Cost Proposal shall reflect bids that will be priced by Contractor on an individual item-by-item or trade-by-trade basis. Tenant shall accept or reject the Cost Proposal within ten (10) business days after receipt thereof. If Tenant rejects the Cost Proposal, then Landlord and Tenant shall work together in good faith in an attempt to agree upon a mutually acceptable Cost Proposal as soon as reasonably practicable, and a Tenant Delay shall be deemed to exist for a number of days equal to the number of days elapsed from Tenant’s rejection of the Cost Proposal until Tenant’s and Landlord’s agreement to a mutually acceptable Cost Proposal.

6. Completion of Landlord’s Work. Landlord shall complete Landlord’s Construction Work and the Tenant Improvements (collectively the “Landlord’s Work”) described in this Work Letter in all respects in accordance with the provisions of the Lease and this Work Letter. Landlord’s Work shall be deemed completed at such time as Landlord shall furnish to Tenant (a) evidence that all Landlord’s Work has been completed and paid for in full (which shall be evidenced by the architect’s certificate of completion), (b) all certifications and approvals with respect to Landlord’s Work that may be required from any Governmental Authority and any board of fire underwriters or similar body for the use and occupancy of the Expansion Premises and (c) an affidavit from Landlord’s architect certifying that all work performed in, on or about the Expansion Premises is in accordance with the Approved TI Plans.

7. Miscellaneous.

     7.1 Headings, Etc. Where applicable in this Work Letter, the singular includes the plural and the masculine or neuter includes the masculine, feminine and neuter. The Section headings of this Work Letter are not a part of this Work Letter and shall have no effect upon the construction or interpretation of any part hereof.

     7.2 Time of the Essence. Time is of the essence with respect to the performance of every provision of this Work Letter in which time of performance is a factor.

     7.3 Covenants. Each provision of this Work Letter performable by Landlord or Tenant shall be deemed both a covenant and a condition.

     7.4 Consent. Whenever consent or approval of either party is required, that party shall not unreasonably withhold, condition or delay such consent or approval, except as may be expressly set forth to the contrary.

EXHIBIT J-6

     7.5 Entire Agreement. The terms of this Work Letter are intended by the parties as a final expression of their agreement with respect to the terms as are included herein, and may not be contradicted by evidence of any prior or contemporaneous agreement, other than the Lease.

     7.6 Invalid Provisions. Any provision of this Work Letter that shall prove to be invalid, void or illegal shall in no way affect, impair or invalidate any other provision hereof, and all other provisions of this Work Letter shall remain in full force and effect and shall be interpreted as if the invalid, void or illegal provision did not exist.

     7.7 Construction. The language in all parts of this Work Letter shall be in all cases construed as a whole according to its fair meaning and not strictly for or against either Landlord or Tenant.

     7.8 Assigns. Each of the covenants, conditions and agreements herein contained shall inure to the benefit of and shall apply to and be binding upon the parties hereto and their respective heirs; legatees; devisees; executors; administrators; and permitted successors, assigns, sublessees. Nothing in this Section 6.8 shall in any way alter the provisions of the Lease restricting assignment or subletting.

     7.9 Authority. That individual or those individuals signing this Work Letter guarantee, warrant and represent that said individual or individuals have the power, authority and legal capacity to sign this Work Letter on behalf of and to bind all entities, corporations, partnerships, limited liability companies, joint venturers or other organizations and entities on whose behalf said individual or individuals have signed.

     7.10 Counterparts. This Work Letter may be executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document.

     7.11 Notice of Completion. Within ten (10) days after completion of construction of the Tenant Improvements, Landlord shall cause a Notice of Completion to be recorded in the office of the Recorder of the County in which the Expansion Building is located and shall furnish a copy thereof to Tenant upon such recordation.

     7.12 No Fee to Landlord. Except as otherwise provided in the Lease, Landlord shall receive no fee for supervision, profit, over overhead in connection with the Landlord’s Construction Work or Tenant Improvement work. In no event shall this Section 7.12 limit the fees that are payable to the architect, engineering consultants, design team, general contractor and subcontractors.

     7.13 Staging Area. During the period prior to the Commencement Date, Tenant shall have the right, without the obligation to pay Rent, to use empty space in the Expansion Building (if any), as designated by Landlord, in its sole and absolute discretion, for the purposes of storing and staging its furniture and equipment only. With respect to this free storage space, if any, Tenant shall be responsible for providing all insurance and for providing any necessary fencing or other protective facilities. Tenant shall hold Landlord harmless and shall indemnify and defend Landlord from and against any and all Claims arising out of or in connection with the use of such storage space by Tenant. Tenant shall be obligated to remove all of the stored materials and its fencing and other facilities within five (5) business days after Tenant’s receipt of written notice from Landlord stating that such staging area is needed by Landlord in which event comparable vacant space, to the extent such space is available (as determined by Landlord in its sole and absolute discretion), shall be made available to Tenant as a substitute staging area.

LETTER OF CREDIT

Date:                     , 200___

	(the “Beneficiary”)
Attention:
L/C. No.:
Loan No.:

Ladies and Gentlemen:

     We establish in favor of Beneficiary our irrevocable and unconditional Letter of Credit numbered as identified above (the “L/C”) for an aggregate amount of $                    , expiring at ___:00 p.m. on                      or, if such day is not a Banking Day, then the next succeeding Banking Day (such date, as extended from time to time, the “Expiry Date”). “Banking Day” means a weekday except a weekday when commercial banks in                      are authorized or required to close.

     We authorize Beneficiary to draw on us (the “Issuer”) for the account of                      (the “Account Party”), under the terms and conditions of this L/C.

     Funds under this L/C are available by presenting the following documentation (the “Drawing Documentation”): (a) the original L/C and (b) a sight draft substantially in the form of Exhibit A, with blanks filled in and bracketed items provided as appropriate. No other evidence of authority, certificate, or documentation is required.

     Drawing Documentation must be presented at Issuer’s office at                      on or before the Expiry Date by personal presentation, courier or messenger service, or fax. Presentation by fax shall be effective upon electronic confirmation of transmission as evidenced by a printed report from the sender’s fax machine. After any fax presentation, but not as a condition to its effectiveness, Beneficiary shall with reasonable promptness deliver the original Drawing Documentation by any other means. Issuer will on request issue a receipt for Drawing Documentation.

     We agree, irrevocably, and irrespective of any claim by any other person, to honor drafts drawn under and in conformity with this L/C, within the maximum amount of this L/C, presented to us on or before the Expiry Date, provided we also receive (on or before the Expiry Date) any other Drawing Documentation this L/C requires.

     We shall pay this L/C only from our own funds by check or wire transfer, in compliance with the Drawing Documentation.

     If Beneficiary presents proper Drawing Documentation to us on or before the Expiry Date, then we shall pay under this L/C at or before the following time (the “Payment Deadline”): (a) if presentment is made at or before noon of any Banking Day, then the close of such Banking Day; and (b) otherwise, the close of the next Banking Day. We waive any right to delay payment beyond the Payment Deadline. If we determine that Drawing Documentation is not proper, then we shall so advise Beneficiary in writing, specifying all grounds for our determination, within one Banking Day after the Payment Deadline.

     Partial drawings are permitted. This L/C shall, except to the extent reduced thereby, survive any partial drawings.

     We shall have no duty or right to inquire into the validity of or basis for any draw under this L/C or any Drawing Documentation. We waive any defense based on fraud or any claim of fraud.

EXHIBIT K-1

     The Expiry Date shall automatically be extended by one year (but never beyond ___ the “Outside Date”) unless, on or before the date thirty (30) days before any Expiry Date, we have given Beneficiary notice that the Expiry Date shall not be so extended (a “Nonrenewal Notice”). We shall promptly upon request confirm any extension of the Expiry Date under the preceding sentence by issuing an amendment to this L/C, but such an amendment is not required for the extension to be effective. We need not give any notice of the Outside Date.

     Beneficiary may from time to time without charge transfer this L/C, in whole but not in part, to any transferee (the “Transferee”). Issuer shall look solely to Beneficiary for payment of any fee for any transfer of this L/C. Beneficiary or Transferee shall consummate such transfer by delivering to Issuer the original of this L/C and a Transfer Notice substantially in the form of Exhibit B, purportedly signed by Beneficiary, and designating Transferee. Issuer shall promptly reissue or amend this L/C in favor of Transferee as Beneficiary. Upon any transfer, all references to Beneficiary shall automatically refer to Transferee, who may then exercise all rights of Beneficiary. Issuer expressly consents to any transfers made from time to time in compliance with this paragraph.

     Any notice to Beneficiary shall be in writing and delivered by hand with receipt acknowledged or by overnight delivery service such as FedEx (with proof of delivery) at the above address, or such other address as Beneficiary may specify by written notice to Issuer. A copy of any such notice shall also be delivered, as a condition to the effectiveness of such notice, to:                      (or such replacement as Beneficiary designates from time to time by written notice).

     No amendment that adversely affects Beneficiary shall be effective without Beneficiary’s written consent.

     This L/C is subject to and incorporates by reference: (a) the Uniform Customs and Practice for Documentary Credits, International Chamber of Commerce Publication No. 500 (the “UCP”); and (b) to the extent not inconsistent with the UCP, Article 5 of the Uniform Commercial Code of the State of New York.

EXHIBIT L-10

time as and whenever such notice shall thereafter be given by one party to the others, at the address last furnished by such Mortgagee. The address of any existing Mortgagee shall be as set forth in its consent to subordination to be attached hereto in connection with such Mortgage. After receipt of such notice from a Mortgagee, no notice thereafter given by either party shall be deemed to have been given unless and until a copy thereof shall have been so given to the Mortgagee. If a Mortgagee so provides or otherwise requires, and notice thereof is given by the Mortgagee as provided above:

          (i) A Mortgagee shall have the absolute right, but no duty or obligation, to cure or correct a breach of this Agreement by the Owner whose property is secured by the Mortgagee’s Mortgage within any applicable cure period provided for such breach by such mortgagor Owner plus an additional period of twenty (20) days after notice to the Mortgagee of expiration of the cure period allowed the mortgagor Owner before the other Owner may exercise any right or remedy to which it may be entitled as a Benefitted Party, except exercise of a self-help right in an emergency situation.

          (ii) Should any prospective Mortgagee require a modification or modifications of this Agreement, which modification or modifications will not cause an increased cost or expense to the Owner whose property is not subject to the Mortgage of such Mortgagee or in any other way materially and adversely change the rights and obligations of such Owner, then and in such event, such Owner agrees that this Agreement may be so modified and agrees to execute whatever documents are reasonably required therefor and deliver the same to the other Owner within ten (10) business days following written requests therefor by the other Owner or prospective Mortgagee.

          11.11 Mortgagee Protection Provisions. No breach or violation of the terms of this Agreement shall defeat or render invalid the lien of any Mortgage encumbering the Parcels 1&2 Land or the Parcel 3 Land or any portions thereof; provided, however, that this Agreement and all provisions hereof shall be binding upon and effective against any subsequent owner of the property or portion thereof whose title is acquired by foreclosure, trustee’s sale, a deed in lieu, or other remedies provided in such Mortgage, but such subsequent owners shall take title free and clear of any of the previous owner’s violations of the terms of this Agreement that occurred before such transfer of title or occupancy.

          11.12 Attorney’s Fees. In the event any legal action, proceeding or arbitration is commenced to interpret or enforce the terms of, or obligations arising out of, this Agreement, or to recover damages for the breach hereof, the party prevailing in any such action, proceeding or arbitration shall be entitled to recover from the non-prevailing party all reasonable attorney’s fees, costs and expenses incurred by the prevailing party.

FORM OF SUBORDINATION, NON-DISTURBANCE
AND ATTORNMENT AGREEMENT

RECORDED AT REQUEST OF
AND WHEN RECORDED RETURN TO:

Attention:

SUBORDINATION, NONDISTURBANCE, AND ATTORNMENT AGREEMENT

     This Subordination, Nondisturbance, and Attornment Agreement (“Agreement”) is made as of                     ,                      between                      (“Lender”), a                     , having its principal place of business at                     ,                     ,                      and Illumina, Inc. (“Tenant”), a Delaware corporation, having its principal place of business at 9855 through 9885 Towne Centre Drive, San Diego, California.

Recitals:

     A. Lender has agreed to make a loan to BMR-9865 Towne Center Drive LLC, a Delaware limited liability company (“Landlord”), to be secured by a deed of trust, dated                     ,                     , and recorded on                     ,                     , as Instrument No.                      , in the Official Records of San Diego County, California (together with all amendments, increases, renewals, modifications, consolidations, spreaders, combinations, supplements, replacements, substitutions, and extensions, either current or future, referred to hereafter as the “Mortgage”) encumbering Landlord’s ownership interest in real property located in San Diego County, State of California. The legal description of the encumbered real property (the “Mortgage Premises”) is set forth in Exhibit A, attached to this Agreement. The Mortgage, together with the promissory note or notes, the loan agreement(s), and other documents executed in connection with it are hereafter collectively referred to as the “Loan Documents”.

     B. On                     ,                     , Tenant and Landlord entered into that certain Lease for a portion of the Mortgage Premises (the “Lease”). The Lease creates a leasehold estate in favor of Tenant for space (the “Leased Premises”) located on the Mortgage Premises.

     C. In connection with execution of the Mortgage, Landlord also executed and delivered to Lender an [Assignment of Leases, Rents and Profits] dated                     ,                     , and recorded on                     ,                     , as Instrument No.                     , in the Official Records of the County Recorder of San Diego, California concerning all rents, issues and profits from the Mortgage Premises. This document, together with all amendments, renewals, modifications consolidations, replacements, substitutions and extensions, is hereafter referred to as the “Assignment of Rents.”

     TO CONFIRM their understanding concerning the legal effect of the Mortgage and the Lease, in consideration of the mutual covenants and agreements contained in this Agreement and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Lender and Tenant, intending to be legally bound, agree and covenant as follows:

     1. Representations and Warranties. Tenant warrants and represents that the Lease is in full force and effect and that, as of the date of this Agreement and to Tenant’s actual knowledge, there is no default under the Lease by Landlord or Tenant.

     2. Tenant Subordination.

          2.1 Subject to the provisions of Section 3, the Loan Documents shall constitute a lien or charge on the Mortgage Premises that is prior and superior to the Lease, to the leasehold estate created by it, and to all rights and privileges of Tenant under it; by this

EXHIBIT M-1

Agreement, the Lease, the leasehold estate created by it, together with all rights and privileges of Tenant under it, is, subject to Section 3, subordinated, at all times, to the lien or charge of the Loan Documents in favor of Lender.

          2.2 By executing this Agreement, Tenant, subject to Section 3, subordinates the Lease and Tenant’s interest under it to the lien right and security title, and terms of the Loan Documents, and to all advances or payments made, or to be made, under any Loan Document.

     3. Nondisturbance.

          3.1 Lender consents to the Lease.

          3.2 Despite Tenant’s subordination under Section 2, Tenant’s peaceful and quiet possession of the Leased Premises shall not be disturbed and Tenant’s rights and privileges under the Lease, shall not be diminished by Lender’s exercise of its rights or remedies under the Loan Documents (subject to the provisions of Section 5), provided that:

               (a) no Default (as defined in the Lease) exists; and

               (b) the Lease has not been canceled or terminated (without regard to whether Landlord or Tenant is then in default under the Lease).

          3.3 Tenant shall not be named or joined in any foreclosure, trustee’s sale, or other proceeding to enforce the Loan Documents unless such joinder shall be legally required to perfect the foreclosure, trustee’s sale, or other proceeding.

     4. Attornment.

          4.1 If Lender shall succeed to Landlord’s interest in the Mortgage Premises by foreclosure of the Mortgage, by deed in lieu of foreclosure, or in any other manner, Tenant shall be bound to Lender (and Lender shall be bound to Tenant) under all the terms, covenants and conditions of the Lease for the balance of its term with the same force and effect as if Lender were the Landlord under the Lease. Tenant shall be deemed to have full and complete attornment to, and to have established direct privity between Tenant and:

               (a) Lender when in possession of the Mortgage Premises;

               (b) a receiver appointed in any action or proceeding to foreclose the Mortgage;

               (c) any party acquiring title to the Mortgage Premises; or

               (d) any successor to Landlord.

          4.2 Tenant’s attornment is self-operating, and it shall continue to be effective without execution of any further instrument by any of the parties to this Agreement or the Lease. Lender agrees to give Tenant written notice if Lender has succeeded to the interest of the Landlord under the Lease. Subject to Section 5, the terms of the Lease are incorporated into this Agreement by reference.

          4.3 If the interests of Landlord under the Lease are transferred by foreclosure of the Mortgage, deed in lieu of foreclosure, or otherwise, to a party other than Lender (“Transferee”), in consideration of, and as condition precedent to, Tenant’s agreement to attorn to any such Transferee, Transferee shall be deemed to have assumed all terms, covenants, and conditions of the Lease to be observed or performed by Landlord from the date on which the Transferee succeeds to Landlord’s interests under the Lease; provided that the liability of any Transferee to Tenant under the terms of the Lease shall be limited in the same manner as Lender’s liability is limited under Section 5.

     5. Lender as Landlord. If Lender shall succeed to the interest of Landlord under the Lease, Lender shall be bound to Tenant under all the terms, covenants and conditions of the Lease, and Tenant shall, from the date of Lender’s succession to the Landlord’s interest under the Lease, have the same remedies against Lender for breach of the Lease that Tenant would have had under the Lease against Landlord; provided, however, that despite anything to the

EXHIBIT M-2

contrary in this Agreement or the Lease, Lender, as successor to the Landlord’s interest, shall not be:

               (a) liable for any act or omission of any previous landlord (including Landlord), provided that the foregoing shall not be construed to limit Tenant’s right to possession of the Leased Premises for the entire term of the Lease, as extended, on the terms and conditions of the Lease;

               (b) subject to any offsets or defenses which Tenant might have had against any previous landlord (including Landlord) relating to any event or occurrence before the date of attornment. The foregoing shall not limit either (a) Tenant’s right to exercise against successor landlord any offset right otherwise available to Tenant because of events occurring after the date of attornment, or (b) successor landlord’s obligation to correct any conditions that existed as of the date of attornment and that violate successor landlord’s obligations as landlord under the Lease;

               (c) unless actually received by Lender, bound by any rent or additional rent that Tenant might have paid for more than one month in advance to any prior landlord (including Landlord), other than, and only to the extent of, prepayments (if any) expressly required under the Lease; or

               (d) bound by an amendment or modification of the Lease which would materially adversely affect any right of Landlord under the Lease made without Lender’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed, except for any amendment or modification evidencing Tenant’s exercise of any rights expressly granted to Tenant in the Lease so long as such amendment or modification reflects the terms and conditions provided with regards to such rights as reflected in the Lease. Notwithstanding the foregoing, any modification, amendment or waiver made or entered into between Landlord and Tenant shall be binding as between Landlord and Tenant.

     6. Notice of Default; Right To Cure. Tenant agrees to give Lender prompt written notice of any known default by Landlord under the Lease. Tenant agrees that, before Tenant exercises any of its rights or remedies under the Lease, Lender shall have the right, but not the obligation, to cure the default within the same time given Landlord in the lease to cure the default, plus an additional thirty (30) days. Tenant agrees that the cure period shall be extended by the time reasonably necessary for Lender to commence foreclosure proceedings and to obtain possession of the Mortgage Premises, provided that this sentence shall not apply if the breach or default by Landlord poses an immediate threat to the health, safety or welfare of Tenant’s employees, customers or invitees at the Leased Premises, provided further that:

               (a) Lender shall notify Tenant of Lender’s intent to effect its remedy within thirty (30) days after receipt of Tenant’s notice;

               (b) Lender initiates immediate steps to foreclose on or to recover possession of the Mortgage Premises;

               (c) Lender initiates legal proceedings to appoint a receiver for the Mortgage Premises or to foreclose on or recover possession of the Mortgage Premises within the thirty (30) day period; and

               (d) Lender prosecutes such proceedings and remedies with due diligence and continuity to completion.

     Tenant also agrees to its use its commercially reasonable efforts to give Lender notice of any casualty damage to the Mortgage Premises, but Tenant’s failure to provide such notice shall not be a default under this Agreement.

     7. Assignment of Rents. If Landlord defaults in its performance of the terms of the Loan Documents, Tenant agrees to recognize the Assignment of Rents made by Landlord to Lender and shall pay to Lender, as assignee, from the time Lender gives Tenant written notice that Landlord is in default under the terms of the Loan Documents, the rents under the Lease, but only those rents that are due or that become due under the terms of the Lease after notice by

EXHIBIT M-3

Lender. Payments of rents to Lender by Tenant under the assignment of rents and Landlord’s default shall continue until the first of the following occurs:

               (a) No further rent is due or payable under the Lease;

               (b) Lender gives Tenant written notice that the Landlord’s default under the Loan Documents has been cured and instructs Tenant that the rents shall thereafter be payable to Landlord; or

               (c) The lien of the Mortgage has been foreclosed and the purchaser at the foreclosure sale (whether Lender or a Transferee) gives Tenant written notice of the foreclosure sale. On giving written notice, the purchaser shall succeed to Landlord’s interests under the Lease, after which time the rents and other benefits due Landlord under the Lease shall be payable to the purchaser as the owner of the Mortgage Premises.

     8. Tenant’s Reliance. When complying with the provisions of Section 7, Tenant shall be entitled to rely on the notices given by Lender under Section 7, and Landlord agrees to release, relieve, protect and indemnify Tenant from and against any and all loss, claim, damage, or liability (including reasonable attorney’s fees) arising out of Tenant’s compliance with such notice.

     Tenant shall be entitled to full credit under the Lease for any rents paid to Lender in accordance with Section 7 to the same extent as if such rents were paid directly to Landlord. Any dispute between Lender (or Lender’s Transferee) and Landlord as to the existence of a default by Landlord under the terms of the Mortgage, the extent or nature of such default, or Lender’s right to foreclosure of the Mortgage, shall be dealt with and adjusted solely between Lender (or Transferee) and Landlord, and Tenant shall not be made a party to any such dispute (unless required by law).

     9. Lender’s Status. Nothing in this Agreement shall be construed to be an agreement by Lender to perform any covenant of the Landlord under the Lease unless and until it obtains title to the Mortgage Premises by power of sale, judicial foreclosure, or deed in lieu of foreclosure, or obtains possession of the Mortgage Premises under the terms of the Loan Documents.

     10. Cancellation of Lease. Tenant agrees that it will not cancel, terminate, or surrender the Lease, except at the normal expiration of the Lease term or as provided in the Lease, or except as otherwise provided in Section 5 above, enter into any agreement, amendment, or modification of the Lease except any agreement, amendment, or modification contemplated by or provided by the terms of the Lease unless Lender gives its prior written consent, which shall not be unreasonably withheld, conditioned or delayed; provided, however, that no Lender consent shall be required pursuant to a termination permitted under the Lease.

     11. Special Covenants. Despite anything in this Agreement or the Lease to the contrary, if Lender acquires title to the Mortgage Premises, Tenant agrees that: Lender shall have the right at any time in connection with the sale or other transfer of the Mortgage Premises to assign the Lease or Lender’s rights under it to any person or entity, and that Lender, its officers, directors, shareholders, agents, and employees shall be released from any further liability under the Lease arising after the date of such transfer, provided that the assignee of Lender’s interest assumes Lender’s obligations under the Lease (including liability for all obligations accruing prior to the date of the assignment), in writing, from the date of such transfer.

     12. Transferee’s Liability. If a Transferee acquires title to the Mortgage Premises:

               (a) Tenant’s recourse against Transferee for default under the Lease shall be limited to the Mortgage Premises or any sale, insurance, or condemnation proceeds from the Mortgage Premises;

               (b) Tenant shall look exclusively to Transferee’s interests described in (a) above for the payment and discharge of any obligations imposed on Transferee under this Agreement or the Lease ; and

               (c) Transferee, its officers, directors, shareholders, agents, and employees are released and relieved of any personal liability under the Lease; and

EXHIBIT M-4

               (d) Tenant shall not collect or attempt to collect any judgment out of any other assets, or from any general or limited partners or shareholders of Transferee.

     Notwithstanding the foregoing, Tenant reserves all rights and remedies available to it in law or in equity against the prior landlord.

     13. Transferee’s Performance Obligations. Subject to the limitations provided in Sections 11 and 12, if a Transferee acquires title to the Mortgage Premises, the Transferee shall perform and recognize: all tenant improvement allowance provisions, all rent-free and rent rebate provisions, and all options and rights of offer, in addition to Landlord’s other obligations under the Lease.

     14. Notice. All notices required by this Agreement shall be given in writing and shall be deemed to have been duly given for all purposes when:

               (a) deposited in the United States mail (by registered or certified mail, return receipt requested, postage prepaid); or

               (b) deposited with a nationally recognized overnight delivery service such as Federal Express or Airborne.
