Each Lender severally agrees, on the terms and conditions hereinafter set forth, to make a single Advance to the Borrower on any Business Day during the period from and including the Effective Date until November 30, 2006 in an amount not to exceed such Lender’s Commitment. Amounts borrowed under this Section 2.01 and repaid pursuant to Section 2.05 or prepaid pursuant to Section 2.09 may not be reborrowed.

SECTION 2.02. Making the Advances. (a) The Borrowing shall be made on notice, given not later than 1:00 P.M. (New York City time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or on the same Business Day of the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, by the Borrower to the Agent, which shall give to each Lender prompt notice thereof by facsimile transmission or electronic mail message. Each such notice of a Borrowing (a “Notice of Borrowing”) shall be by telephone, confirmed promptly in writing, or facsimile transmission or electronic mail message, in substantially the form of Exhibit B hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for each such Advance. The Agent shall provide the Borrower with an acknowledgment of receipt of each Notice of Borrowing specifying a Eurodollar Rate Advance on the next Business Day. Each Lender shall, before 2:00 P.M. (New York City time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Agent at the Agent’s Account, in same day funds, such Lender’s ratable portion of such Borrowing. Promptly after the Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower no later than 4:00 P.M. (New York City time) at the Agent’s address referred to in Section 8.02.

(b) Anything in Section 2.02 (a) above to the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less than $5,000,000 or if the obligation of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to Section 2.07 or 2.11 and (ii) the Eurodollar Rate Advances may not be outstanding as part of more than ten separate Borrowings.

(c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

(d) Unless the Agent shall have received notice from a Lender prior to the time of any Borrowing that such Lender will not make available to the Agent such Lender’s ratable portion of such Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with Section 2.02(a) and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(e) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but

12

no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

Notwithstanding any other provision of this Agreement, if any Lender shall notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation, after the date hereof, makes it unlawful, or any central bank or other governmental authority having jurisdiction over a Lender asserts after the date hereof that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, then, on notice thereof and demand therefor by such Lender to the Borrower through the Agent, (a) each Eurodollar Rate Advance will automatically, upon the later of such demand and the date required by applicable law, Convert into a Base Rate Advance and (b) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender.

SECTION 2.12. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the Notes, irrespective of any right of counterclaim or set-off, not later than 12:00 noon (New York City time) on the day when due in U.S. dollars to the Agent at the Agent’s Account in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or facility fees ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and

16

Acceptance, the Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder or under the Note held by such Lender, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due.

(c) All computations of interest based on the Base Rate and of utilization fee (to the extent such utilization fee relates to Base Rate Advances) shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of facility fees or utilization fees (to the extent such utilization fee relates to Eurodollar Advances or shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or facility fees are payable. Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

SECTION 2.13. Taxes. (a) Except as provided in Section 2.13(f), any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Agent, taxes imposed on its overall net income, and franchise taxes imposed in lieu thereof, by the jurisdiction under the laws of which such Lender or the Agent is organized or any political subdivision thereof and, in the case of each Lender, taxes imposed on its overall net income, and franchise taxes imposed in lieu thereof, by the jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Lender or the Agent, (i) except as provided in Section 2.13(f), the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender or the Agent receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other governmental authority in accordance with applicable law.

(b) In addition, the Borrower shall pay when due any present or future stamp or documentary taxes or any other excise, property or similar taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or any other documents to be delivered hereunder or from the execution, delivery or registration of, performance under or otherwise with respect to, this Agreement or the Notes or any other documents to be delivered hereunder (hereinafter referred to as “Other Taxes”).

(c) The Borrower shall indemnify each Lender and the Agent for and hold it harmless against the full amount of Taxes or Other Taxes and for the full amount of taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.13, imposed on or paid by such Lender or the Agent, as the case may be,

17

and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. These indemnification payments shall be made within 30 days from the date on which such Lender or the Agent makes written demand therefor, accompanied by a calculation in reasonable detail of the amount demanded and evidence of the Taxes, Other Taxes or taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.13 imposed or paid by the Agent or any Lender.

(d) Within 30 days after the date of any payment of Taxes, by the Borrower pursuant to this Section 2.13, the Borrower shall furnish to the Agent, at its address referred to in Section 8.02, evidence reasonably satisfactory to the Agent of such payment.

(e) Each Lender organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender, and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender in the case of each other Lender, and from time to time thereafter as reasonably requested in writing by the Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of the Agent and the Borrower with two original Internal Revenue Service forms W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or the Notes. In addition to the forms described in the immediately preceding sentence, each Lender organized under the laws of a jurisdiction outside the United States shall, upon the request of the Borrower or the Agent in writing, (i) provide each of the Agent and the Borrower with two further copies of such forms or other appropriate certification of such forms on or before the date that any such form expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form delivered to the Borrower, and (ii) obtain such extensions of the time for the filing and renew such forms and certifications thereof as may be reasonably requested by the Borrower or the Agent. If the form (or forms) provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form; provided, however, that, if at the date of the Assignment and Acceptance pursuant to which a Lender assignee becomes a party to this Agreement, the Lender assignor was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender assignee on such date. For purposes of this subsection (e), the term “United States” shall have the meaning specified in Section 7701 of the Internal Revenue Code.

(f) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form described in Section 2.13(e) or failed to seek an extension of the time for filing such successor form as required in writing to do so by the Agent or the Borrower in accordance with Section 2.13(e) (other than if such failure is due to a change in law occurring subsequent to the date on which a form originally was required to be provided, or if such form otherwise is not required under subsection (e) above), such Lender shall not be entitled to indemnification under Section 2.13(a) or (c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that, should a Lender become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps (at such Lender’s expense) as the Lender shall reasonably request to assist the Lender to recover such Taxes.

(g) In the event that an additional payment is made under Section 2.13(a) or (c) for the account of any Lender or Agent, such Lender or Agent, as applicable, shall determine whether it has received or been granted a Tax Benefit (as defined hereinafter), and if such Lender or Agent, as applicable, in its sole discretion, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or repayment of, any tax paid or payable by or for it in respect of or calculated with reference to such payment or the deduction or withholding giving rise to such payment (a “Tax Benefit”), such Lender or Agent shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment pay to the Borrower such amount as such Lender shall, in its sole discretion, have determined to be attributable to such Tax Benefit and which will leave such Lender (after such payment) in no worse position than it would have been in if the Borrower had not been required to make such payment, deduction or withholding. Nothing herein contained shall interfere with the right of a Lender to arrange its tax affairs in whatever manner it

18

thinks fit nor oblige any Lender or Agent to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Lender or Agent to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled.

(h) If the Borrower is required to pay any amount to any Lender or the Agent pursuant to subsection (a), (b), or (c) of this Section 2.13, then such Lender or the Agent shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office so as to eliminate (or, if elimination is not reasonably possible, to minimize) any such additional payment by the Borrower which may thereafter accrue, if such change in the sole judgment of such Lender or the Agent, as the case may be, is not otherwise disadvantageous to such Lender or the Agent.

(i) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower and each Lender and Agent contained in this Section 2.13 shall survive the repayment of the Advances and the other obligations hereunder or under the Notes and the termination of the Commitments hereunder.

SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances owing to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

SECTION 2.15. Use of Proceeds. The proceeds of the Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely to finance the acquisition of Lumigen Inc. (the “Acquisition”), and to pay related costs and expenses.

SECTION 2.16. Replacement of Lenders. If any Lender (a) requests the payment of additional amounts under Sections 2.10 or 2.13, (b) is unable to make Eurodollar Rate Advances in accordance with Section 2.11, (c) is a Defaulting Lender, or (d) refuses to consent to a proposed amendment, waiver or other modification which requires the consent of all Lenders and has been approved by Required Lenders (any such Lender, an “Affected Lender”), then Borrower may, at its option replace such Lender with an Eligible Assignee (which may be another Lender or an Affiliate of a Lender) which executes and delivers to the Affected Lender an Assignment and Acceptance with respect to the Commitments of the Affected Lender, and in such case the Affected Lender shall execute and deliver to such replacement lender an Assignment and Acceptance and, in consideration of the purchase, at par, without premium or penalty, of the Note of such Affected Lender and the assumption of its obligations hereunder, assign to the replacement lender its Commitments and outstanding Advances hereunder. In the event of an assignment under this Section, the processing fee referred to in Section 8.07 hereof shall be paid by the Borrower, provided, that no such fee shall be paid if the assignment is to an existing Lender.

Without limitation of the generality of the foregoing, the Agent: (i) may treat the payee of any Note as the holder thereof until the Agent receives and accepts an Assignment and Acceptance entered into by the Lender that is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (iv) shall not have any duty to ascertain or to inquire as to the performance, observance or satisfaction of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or the existence at any time of any Default or to inspect the property (including the books and records) of the Borrower; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; and (vi) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile transmission or electronic mail message) believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 7.03. CNAI and Affiliates. With respect to its Commitment, the Advances made by it and the Note issued to it, CNAI shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include CNAI in its individual capacity. CNAI and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, the Borrower, any of its Subsidiaries and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if CNAI were not the Agent and without any duty to account therefor to the Lenders. The Agent shall have no duty to disclose any information obtained or received by it or any of its Affiliates relating to the Borrower or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as Agent.

SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

29

SECTION 7.05. Indemnification. The Lenders agree to indemnify the Agent (to the extent not reimbursed by the Borrower), ratably according to the respective principal amounts of the Notes then held by each of them (or if no Notes are at the time outstanding or if any Notes are held by Persons that are not Lenders, ratably according to the respective amounts of their Commitments), from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Agent under this Agreement (collectively, the “Indemnified Costs”), provided that no Lender shall be liable for any portion of the Indemnified Costs resulting from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by the Agent, any Lender or a third party.

SECTION 7.06. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Agent, provided that the appointment of any such successor Agent shall be subject to the consent of the Borrower (not to be unreasonably withheld or delayed) so long as no Event of Default has occurred and is continuing. If no successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

Notwithstanding any other provisions to the contrary herein, no obligation to indemnify and hold harmless any Indemnified Party under this Section arises from a failure by such Indemnified Party to comply with any laws, regulations, rules or orders that may apply to its business, or a failure by such Indemnified Party to possess the capacity to participate in the transactions contemplated by this Agreement or to take all actions necessary to authorize its participation in such transactions. The Borrower also agrees not to assert any claim for special, indirect, consequential or punitive damages against the Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability arising out of or otherwise relating to the Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances.

(c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Advance, as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09 or 2.11, acceleration of the maturity of the Notes pursuant to Section 6.01 or for any other reason, the Borrower shall, within seven days following demand by such Lender accompanied by a calculation in reasonable detail of the amount demanded (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.10, 2.13 and 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the acceleration of the Advances pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement and the Note held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Lender and its Affiliates may have.

SECTION 8.06. Binding Effect. This Agreement shall become effective (other than Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set forth in Section 3.01) when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified by each Initial Lender that such Initial Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

SECTION 8.07. Assignments and Participations. (a) Each Lender may assign to one or more Persons all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender’s rights and obligations under this Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note subject to such assignment and a processing and recordation fee of $3,500. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its rights under Sections 2.11, 2.14 and 8.04 to the extent any claim thereunder relates to an event arising prior to such assignment) and be released from its obligations under this Agreement (other than its obligations under Section 7.05 to the extent any claim thereunder relates to an event arising prior to such assignment) (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this

33

Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Agent in exchange for the surrendered Note a new Note to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, a new Note to the order of the assigning Lender in an amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A hereto.

(e) Each Lender may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) approved by the Borrower (unless an Event of Default has occurred and is continuing at the time any participation is effected), such approval not to be unreasonably withheld or delayed (it being understood that any objection by the Borrower to any Person reasonably considered by the Borrower to be a competitor, or an Affiliate of a competitor, of the Borrower shall be deemed to be not unreasonable); in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation.

(f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, in each case, that is an Eligible Assignee or has otherwise been approved by the Borrower, or an SPC, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant or SPC shall agree to preserve

34

the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender in accordance with Section 8.08.

(g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Advances owing to it and the Note held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle sponsored, administered or managed by the Granting Lender (a “SPC”), identified as such in writing from time to time by the Granting Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance, (ii) no SPC shall, solely by reason of any such grant or any Advance made by such SPC thereunder, be deemed to be a Lender hereunder, and (iii) the Granting Lender shall not be relieved of any of its obligations under this Agreement by reason of any such grant and, if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof with respect to any claim arising out of, or relating to, this Agreement or any Note or the performance or non-performance of any obligation thereunder. In addition, notwithstanding anything to the contrary contained in this Section 8.07(h), any SPC may (A) with notice to, but without (except as provided below) the prior written consent of, the Borrower and the Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advances to the Granting Lender or, with the consent of the Borrower and the Agent, to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (B) disclose on a confidential basis (subject to the same terms as set forth in Section 8.08 with respect to the disclosure of any Confidential Information to assignees and participants) any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. For the avoidance of doubt, notwithstanding anything in this Section 8.07(h) to the contrary, no SPC nor any institution providing liquidity and/or credit support to, or for the account of, such SPC shall be entitled to the benefits of a Lender under this Agreement, including, but not limited to, the benefits under Sections 2.10 or 2.13 or any indemnification provisions, and the Granting Lender shall for all purposes, including any consent, approval or waiver hereunder, continue to be the Lender entitled to all the rights and benefits of a Lender under this Agreement, and bound by the obligations of a Lender hereunder, provided that in any case any such SPC (or any assignee thereof) shall be entitled to receive payments due in respect of any Advance made by such SPC hereunder. The Granting Lender hereby agrees to indemnify and hold harmless the Borrower from any additional cost or expense incurred by the Borrower in connection with the transactions contemplated by this Section 8.07(h) with respect to any grant made by such Granting Lender to any SPC. This section may not be amended without the written consent of the SPC.

SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall disclose any Confidential Information to any other Person without the consent of the Borrower, other than (a) to the Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 8.07(f), to actual or prospective assignees and participants and SPCs, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process; provided that unless specifically prohibited by applicable law or court order each Lender and the Agent shall use reasonable efforts to endeavor to notify the Borrower of any request of any governmental authority (other than any such request in connection with an examination of the financial condition or operation of such Lender or the Agent) for disclosure of any confidential information prior to disclosure thereof and (c) as requested or required by any state, federal or foreign authority or examiner regulating banks or banking. Before the Agent or any Lender discloses any Confidential Information to

35

any actual or prospective assignees and participants or SPCs, the Agent or Lender wishing to disclose the Confidential Information shall obtain the written agreement of the proposed recipient to keep the information confidential. Each such written agreement shall state that it is for the benefit of and may be enforced by Borrower and a copy of the written agreement signed by the proposed recipient shall be sent to Borrower.

SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 8.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes in the courts of any jurisdiction.

(b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

SECTION 8.12. Patriot Act Notice. Each Lender and the Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Agent or any Lenders in order to assist the Agent and the Lenders in maintaining compliance with the Patriot Act.

36

SECTION 8.13. Waiver of Jury Trial. Each of the Borrower, the Agent and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the Notes or the actions of the Agent or any Lender in the negotiation, administration, performance or enforcement thereof.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.
