NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization, Operations and Basis of Accounting

Response Genetics, Inc. (the “Company”) was incorporated in the state of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing unique molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin wax. In August 2000, the Company changed its name to Response Genetics, Inc. In November, 2006 the company established a wholly owned subsidiary in Edinburgh, Scotland.

Our goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues. Our pharmacogenomic analysis of clinical trial specimens for the pharmaceutical industry may provide data that will lead to a better understanding of the molecular basis for response to specific drugs and, therefore lead to individualized treatment. We are focusing our efforts in the following areas:

•

Launching our ResponseDX tests;

•

Developing diagnostic tests for assessing the risk of cancer recurrence, prediction of chemotherapy response and tumor classification in cancer patients;

•

Expanding our pharmacogenomic testing services business and creating a standardized and integrated testing platform into the major markets of the healthcare industry including outside of the United States.

Our patented technologies enable us to reliably and consistently extract the nucleic acids RNA and DNA from tumor specimens that are stored as formalin-fixed and paraffin-embedded, or FFPE, specimens and thereby to analyze genetic information contained in these tissues. This is significant because the majority of patients diagnosed with cancer have a tumor biopsy sample stored in paraffin, while only a small percentage of patients’ tumor specimens are frozen. Our technologies also enable us to use the FFPE patient biopsies for the development of diagnostic tests. To our knowledge, we are the first company to generate clinically relevant information regarding the risks of recurrence of cancer or chemotherapy response using approximately 30,000 genes available from microarray profiling of FFPE specimens.

Clinical studies have shown that not all cancer chemotherapy works effectively in every patient, and that a number of patients receive therapy that has no benefit to them and may potentially even be harmful. Our goal is to provide physicians and cancer patients with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues.

Response DX™

The outcome of cancer chemotherapy is highly variable due to genetic differences among patients. Some patients respond well with tumor shrinkage and increase in life span. Other patients do not obtain benefit from the same therapy but may still experience toxic side effects as well as delay in effective treatment and psychological trauma.

At present most chemotherapy regimens are administered without any pre-selection of patients on the basis of their particular genetics. However recent development of very sensitive molecular technologies has enabled researchers to identify and measure genetic and biochemical factors in patients’ tissues that can predict the probability of success or failure of many currently used anti-cancer agents. In order to increase the chances of a better chemotherapy outcome for cancer patients, RGI is developing genetic tests that will measure predictive factors for tumor response in tumor tissue samples. We have begun offering tests for non-small cell lung cancer (NSCLC) and colorectal cancer (CRC) patients’ tumor tissue through our CLIA registered laboratory and we anticipate offering additional tests for esophageal and pancreatic cancer in the future.

The Company primarily derives its revenue by providing pharmacogenomic testing services to pharmaceutical companies in the United States, Asia and Europe.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 8-03 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the fiscal year. The financial statements should be read in conjunction with the Company’s Audited December 31, 2007 and 2006 consolidated financial statements and accompanying notes included in the Company’s Form 10-KSB previously filed with the SEC.

2. Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of Response Genetics, Inc. and its wholly owned subsidiary, Response Genetics, Ltd., a Scottish corporation, which was incorporated in October 2006. All significant intercompany transactions and balances have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity at date of purchase of three months or less to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments. The Company’s cash equivalents are comprised of cash on hand, deposits in banks and money market investments.

Accounts Receivable

The Company invoices its clients as specimens are processed and any other contractual obligations are met. The Company’s contracts with clients typically require payment within 45 days of the date of invoice. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its clients to make required payments. The Company specifically analyzes accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, the Company’s clients have primarily been large pharmaceutical companies. As a result, bad debts to date have been minimal. There were no allowances for doubtful accounts recorded at December 31, 2007 and March 31, 2008.

2. Summary of Significant Accounting Policies - (continued)

Supply Inventories

The Company purchases reagents, analyte specific reagents, and other supplies to conduct various laboratory tests on an as needed basis with turnover typically within 30 days of purchase. The Company’s primary product is data generated from its pharmacogenomic testing services. Hence, the Company does not record either product or supply inventories as part of its financial statements as these are considered immaterial to the Company’s financial position and results of operations.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the double declining balance method over the estimated useful lives of the assets. The Company has determined the estimated useful lives of its property and equipment, as follows:

Laboratory equipment		5 to 7 years
Furniture and Equipment		5 to 7 years
Leasehold Improvements		Shorter of the useful life or the lease term (5 to 7 years)

Maintenance and repairs are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the related accounts and the resulting gain or loss is reflected in the statements of operations.

Revenue Recognition

Revenues are derived from pharmacogenomic testing services provided to pharmaceutical companies and are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, the Company may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, the Company records this advance as deferred revenue and recognizes the revenue as the specimens are processed or at the end of the contract period, as appropriate.

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction, or (“RT-PCR”) and quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

2. Summary of Significant Accounting Policies - (continued)

Patent License Fees

The Company has licensed technology for the extraction of mRNA from formalin-fixed, paraffin-embedded tumor specimens from the University of Southern California (“USC”). Under the terms of the license agreement, the Company is required to pay royalties to USC based on the revenue generated by use of this technology. The Company maintains a non-exclusive license to use the polymerase chain reaction (“PCR”), homogenous PCR, and reverse transcription PCR processes of Roche Molecular Systems, Inc. (“Roche”). The Company pays Roche Molecular Systems a royalty fee based on revenue that the Company generates through use of this technology. The Company accrues for such royalties at the time revenue is recognized. Such royalties are included in cost of revenue in the accompanying statements of operations.

Research and Development

The Company expenses costs associated with research and development activities as incurred. Research and development costs are allocated on a pro rata basis using the number of research-only specimens that are processed by the Company versus specimens that are processed and paid for by various third parties via contract. Research and development costs include employee costs (salaries, payroll taxes, benefits, and travel), equipment depreciation and warranties and maintenance, laboratory supplies, primers and probes, reagents, patent costs and occupancy costs.

Income Taxes

Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company adopted the Financial Accounting Standards Board's Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109" ("FIN 48") effective January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. At the date of adoption, and as of December 31, 2007 and March 31, 2008, the Company does not have a liability for unrecognized tax benefits.

Stock-Based Compensation

The Company accounts for stock-based compensation under the guidance of Statement of Financial Accounting Standards No. 123(R), “Share-Based Payments,” (“SFAS 123(R)”) which requires the measurement and recognition of compensation expense for all share-based payment awards based on estimated fair values.

Under the modified prospective method of SFAS No. 123(R), compensation expense is recognized for all stock-based payments granted prior to, but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123 and compensation expense for all stock based payments granted after January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123(R). The Company’s financial results for the prior periods have not been restated. Stock-based compensation expense recognized under SFAS 123(R) was $(33,951) and $319,603 for the three months ended March 31, 2007 and 2008, respectively. The Company accounts for equity instruments issued to non-employees in accordance with the provisions of Emerging Issues Task Force No. 96-18, Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (“EITF 96-18”). Under EITF 96-18, stock option awards issued to non-employees are accounted for at fair value using the Black-Scholes option-pricing model.

Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management has identified revenue, the fair value of its preferred and common stock and the assessment of the realizability of deferred income tax assets as areas where significant estimates and assumptions have been made in preparing the financial statements.

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the asset is not recoverable, the Company’s carrying value of the asset would be reduced to its estimated fair value, which is measured by future discounted cash flows.

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign operations are determined using local currency as the functional currency. Assets and liabilities of these operations are translated at the exchange rate in effect at each period-end. Statement of operations amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ equity.

Comprehensive Income (Loss)

Comprehensive income (loss) encompasses the change in equity from transactions and other events and circumstances from non-owner sources and the Company’s net income (loss). Accumulated other comprehensive loss is comprised of foreign currency translation adjustments for the year ended December 31, 2007 and for the three months ended March 31, 2008.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash, cash equivalents, accounts receivable, accounts payable, and accrued expenses, approximate fair value due to the short term nature of these financial instruments.

Reclassifications

Prior year amounts in the consolidated financial statements have been reclassified to conform with the current year presentation. Reclassified amounts had no impact on the company’s net losses.

Concentration of Credit Risk and Clients and Limited Suppliers

Cash and cash equivalents consist of financial instruments that potentially subject the Company to concentrations of credit risk to the extent recorded on the balance sheets. The Company maintains cash in United States financial institutions in excess of Federal Deposit Insurance Corporation limitations. In addition, the Company has invested its excess cash in money market instruments which are not insured under the Federal Deposit Insurance Corporation. The Company has not incurred any losses on these cash balances as of March 31, 2008. At December 31, 2007 and March 31, 2008, the Company had cash on deposit that was in excess of the federally insured limit of $100,000. At March 31, 2008, approximately $885,093 of cash was held outside of the United States.

Many of the supplies and reagents used in the Company’s testing process are procured by a limited number of suppliers. Any supply interruption or an increase in demand beyond the suppliers’ capabilities could have an adverse impact on the Company’s business. Management believes it can identify alternative sources, if necessary, but it is possible such sources may not be identified in sufficient time to avoid an adverse impact on its business. Refer also to Notes 6 and 7 for further discussion regarding these supply agreements.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) 157, “Fair Value Measurements,” and defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years.

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 159, The Fair Value Option for Financial Assets and Financial Liabilities - an amendment of FASB Statement No. 115,” which permits entities to measure many financial instruments and certain other items at fair value, and establishes the presentation and disclosure requirements to facilitate comparisons between entities choosing different measurement attributes for similar types of assets. SFAS 159 is effective for fiscal years ending after November 15, 2007

In December 2007, FASB issued SFAS No. 141(R), “Business Combinations”, an amendment of SFAS No. 141, which improves the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. SFAS 141(R) applies for all business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We do not expect adoption of SFAS 141(R) to have a material impact on the Company’s financial statements.

In December 2007, FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements - an amendment of Accounting Research Bulletin No. 51 ,” which amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 is effective for fiscal years beginning on or after December 15, 2008. We do not expect adoption of SFAS 160 to have a material impact on the Company’s financial statements.

In March 2008, FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133” which establishes the disclosure requirements for derivative instruments and for hedging activities. This Statement amends and expands the disclosure requirements of Statement 133 with the intent to provide users of financial statements with an enhanced understanding of derivative instruments and hedging activities. SFAS 61 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early adoption encouraged. We do not expect adoption of SFAS 160 to have a material impact on the Company’s financial statements.

5. Loss Per Share

The Company calculates net loss per share in accordance with SFAS No. 128, Earnings Per Share (“SFAS No. 128”). Under the provisions of SFAS No. 128, basic net loss per share is computed by dividing the net loss attributable to common stockholders for the period by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents then outstanding. Common stock equivalents consist of shares of common stock issuable upon the conversion of convertible preferred stock and upon the exercise of stock options.

The following table sets forth the computation for basic and diluted loss per share:

	Three Months Ended March 31,
	2007			2008
	(Unaudited)
Numerator:
Net loss	$	(757,942	)	$	(1,724,970	)
Series B convertible preferred stock dividends		(233,561	)		—
Numerator for basic earnings per share - income (loss) available to common stockholders		(991,503	)		(1,724,970	)
Numerator for diluted earnings per share — income (loss) available to common stockholders	$	(991,503	)	$	(1,724,970	)
Denominator:
Denominator for basic earnings per share — weighted-average shares		2,726,320			10,239,276
Dilutive potential common shares		—			—
Denominator for diluted earnings per share — adjusted weighted-average shares and assumed conversions		2,726,320			10,239,276
Basic Loss per share	$	(0.36	)	$	(0.17	)
Diluted Loss per share	$	(0.36	)	$	(0.17	)

Outstanding stock options and warrants to purchase 210,000 shares and 1,310,190 shares for the three months ended March 31, 2007 and 2008, respectively, were excluded from the calculation of diluted loss per share as their effect would have been antidilutive. The assumed conversion of the Series A Junior Convertible Preferred Stock and the Series B Convertible Preferred Stock were excluded from the calculation of diluted loss per share for the period ended March 31, 2007 as their effect would have been antidilutive.

10. Income Taxes

Deferred income taxes result from temporary differences between income tax and financial reporting computed at the effective income tax rate. The Company has established a valuation allowance against its net deferred tax asset due to the uncertainty surrounding the realization of such asset. Management periodically evaluates the recoverability of the deferred tax assets. At such time it is determined that it is more likely than not that deferred tax assets are realizable, the valuation allowance will be reduced.

The Company adopted the Financial Accounting Standards Board’s Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”) effective January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. At the date of adoption, and as of December 31, 2007 and March 31, 2008, the Company does not have a liability for unrecognized tax benefits.

We file U.S. federal, U.S. state, and foreign tax returns. Our major tax jurisdictions are U.S. federal and the State of California and are subject to tax examinations for the years 1999 through 2007.

11. Defined Contribution Plan

The Company maintains a defined contribution plan covering substantially all of its employees meeting minimum age and service requirements. Participation in the plan is optional. At this time, the Company does not provide matching contributions to the defined contribution plan.

12. Related Party Transactions

While employed at USC, Kathleen Danenberg, president, chief executive officer and director, developed and patented (United States Patent 6,248,535; Danenberg , et al., Method For Isolation of RNA From Formalin-Fixed Paraffin-Embedded Tissue Specimens) an extraction method that allowed reliable and consistent isolation of RNA from FFPE suitable for RT-PCR. USC retains ownership of this patent but has exclusively licensed this technology to the Company. In consideration for this license, the Company is obligated to pay royalties to USC, as a percentage of net sales of products or services using the technology, and to meet a certain minimum in royalty payments. Pursuant to USC policy, the inventors of technology owned by the University and then licensed for commercialization are paid a portion of royalties received by the University from the licensed technology. USC therefore pays a portion of royalties received from the Company to Ms. Danenberg in recognition of her invention. Amounts paid to Ms. Danenberg amounted to $14,797 and $0 for the three months ended March 31, 2007 and 2008, respectively.

Overview

Our technology

All of our tests are based on the polymerase chain reaction (PCR), which is a sensitive, precise and reliable technology that gives numerical values that are not dependent on subjective interpretation by pathologists, as are antibody-based tests. We developed and extensively validated technology to perform quantitative PCR analysis of gene expressions in formalin-fixed paraffin embedded (FFPE) tumor tissues. We have used our technological expertise in many projects for the pharmaceutical industry and for many collaborative scientific studies. The benefit of our capability for patients is that in many cases, no tissue samples other than the pre-treatment diagnostic biopsy will be required for the biomarker analysis.

We developed ResponseDX in part by using our technologies to extract genetic information from FFPE tumor specimens. Our technology provides gene expression information for each patient's tumor tissue specimen. Our mission is to help doctors and patients choose the most effective cancer treatment options - the first time - based on a patient's unique genetic code. We assess non-small cell lung cancer (NSCLC) and/or colorectal cancer (CRC) patients' tumor tissue specimens through our ResponseDX: Lung ™ and ResponseDX: Colon™ test suites. The test results may help doctors and patients decide the best course of treatment for patients.

Since February 2008, ResponseDX: Lung and ResponseDX: Colon tests are commercially available through our laboratory located in Los Angeles, California, which is registered under the Clinical Laboratory Improvement Amendments of 1988 (CLIA).

ResponseDX: Lung™ and ResponseDX: Colon™

ResponseDX: Lung™ comprises four tests: ERCCI, RRMI, KRAS Mutation and EGFR Amplification and ResponseDX: Colon™ comprises three tests: ERCCI, KRAS Mutation and TS. The Response DX test measures the RNA expression of ERCCI and RRMI by RT-PCR from a patient's tumor tissue. PCR analysis of DNA from the patient's sample is used to determine EGFR amplification and KRAS mutational status. The ERCCI test is a test for the probability of response to platin-based therapies and the analysis of RRMI tests for the probability of response to gemcitabine-based therapies. We determine the ranges of ERCCI expression and RRMI expression that classify a patient's tumor into categories of the low and high probability of responding to platin-based therapy and gemcitabine-based therapies, respectively. The EFGR Amplitication test assesses the probability of benefit from EGFR-directed therapy. We determine if the EGFR gene is amplified, which is associated with better response to EGFR-based therapy. The KRAS gene mutation test identifies tumors that have low probability of response to EGFR-directed therapy. This test utilizes a 7 mutation panel to identify KRAS gene mutations in a sample that are associated with low response to EGFR-directed therapy. The TS gene expression test measures the probability of response to 5- fluorouracil (5-FU)-based chemotherapy.

Diagnostic Tests for Other Cancers

In addition to ResponseDx: Lung and ResponseDx: Colon, we are developing and intend to commercialize tests of other types of cancer that identify genetic profiles of tumors that are more aggressive and recur rapidly after surgery. We also are identifying genetic profiles of tumors that are more or less responsive to a particular chemotherapy. Following the development of tests to predict the risk of recurrence after surgery, we intend to develop tests to determine the most active chemotherapy regimen for the individual patient at risk. Once developed and after obtaining any necessary regulatory approvals, we intend to leverage our relationships in the healthcare industry to market, sell or license these tests as a means for physicians to determine the courses of cancer treatment.

Expansion of our pharmacogenomic testing services business

We have started the expansion of our pharmacogenomic testing services business into major markets of the healthcare industry outside of the United States. We have established service laboratories in Europe and Japan, and are working to establish a service laboratory in China, through collaboration with some of our current clients in the pharmaceutical industry. The pharmaceutical industry is in need of standardized integrated worldwide analysis of clinical trial specimens. It is important to the pharmaceutical industry and the regulatory agencies that the same analytical methods are used for each clinical trial sample around the world so that the data can be easily compared and used for global drug development. Also, export of clinical trial specimens to the United States is restricted from some areas of the world, such as China. Our goal is to offer an analysis of patient specimens and generate consistent data based on integrated common platforms and technology into the major markets of the healthcare industry including outside of the United States. To our knowledge, we will be the only company offering consistent pharmacogenomic analysis to the industry across geographical regions.

There are no assurances that the Company will be able to continue making its current ResponseDx tests available, or make additional ResponseDx tests available; will be able to develop and commercialize tests of other types of cancer; or will be able to expand our pharmacogenomic testing service business.

We anticipate that, over the next 12 months, a substantial portion of our capital resources and efforts will be focused on research and development to bring to market a series of diagnostic tests for cancer patients, to establish a pharmacogenomics database that is of commercial value, to establish laboratories overseas in collaboration with certain of our current pharmaceutical clients and for other general corporate purposes.

Research and development expenses represented 13% and 15.9% of our total operating expenses for the quarters ended March 31, 2007 and March 31, 2008, respectively. Major components of the $603,385 in research and development expenses for the quarter ended March 31, 2008 included supplies and reagents for our research activities, personnel costs, occupancy costs, equipment warranties and service, patent fees, insurance, business consulting and sample procurement costs.

On November 1, 2007 we announced plans to make our test for Excision-Repair Cross-Complementing 1 (ERCC-1) gene expression for platin-based chemotherapy resistance available to selected institutions and clinical practice groups in the first quarter of 2008. Since February, 2008, the ERCC-1 test, as part of our ResponseDX: Lung and ResponseDX: Colon tests, is commercially available through our laboratory located in Los Angeles, CA, which is registered under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). The initial launch will provide additional information about the clinical utility of ERCC-1 in the treatment of Non-Small Cell Lung Cancer (NSCLC); clinical practice activities such as sample acquisition, logistics, patient and physician communication; and the use of the test in normal clinical practice related to NSCLC.

Previously, we had announced the publication of results from a prospective study published in the July 1, 2007 issue of the Journal of Clinical Oncology. The data indicated that high expression of ERCC-1 in patients with advanced NSCLC predicts resistance to platin-based chemotherapy. These findings suggest that the measurement of ERCC-1 levels would play a role in individualizing treatment therapies for certain lung cancer patients. The multi-center, randomized study was designed to determine the overall response rate (complete plus partial responses) of patients with stage IIIb or IV NSCLC to cisplatin-based therapy by determining levels of the biomarker ERCC-1 mRNA in a paraffin-embedded tissue biopsy before administering treatment. We believe that this is the first prospective study using a biomarker to predict chemotherapy response in lung cancer. At this time we cannot reasonably estimate the expected impact, if any, or that our ERCC-1 test will have on our liquidity and future realization of revenues.

On April 4, 2008, the board of directors increased the size of the board to seven members and elected John Ferrara to the board as a director of the Company. The board also determined that Mr. Ferrara is an “independent director” pursuant to the requirements for memberships established by NASD Market place Rule 4350(c)(4). We filed a Form 8-K on April 7, 2008 reporting this event.

On April 30, 2008, the board of directors increased the size of the board to eight members and elected David Gandara to the board as a director of the Company. The board also determined that Mr. Gandara is an “independent director” pursuant to the requirements for memberships established by NASD Market place Rule 4350(c)(4). We filed a Form 8-K on May 6, 2008 reporting this event.

Critical Accounting Policies and Significant Judgments and Estimates

This discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as revenues and expenses during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from those estimates under different assumptions or conditions. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our financial statements.

Revenue Recognition

Revenues are derived from services provided to pharmaceutical companies and are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through our laboratory under a specified contractual protocol. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, we may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, we record this advance as deferred revenue and recognize the revenue as the specimens are processed or at the end of the contract period, as appropriate.

We are subject to potentially significant variations in the timing of revenue recognized from period to period due to a variety of factors including: (1) the timing of when specimens are submitted to us for testing; and (2) the specific terms, such as minimum assay requirements in any given period, advance payment requirements, and term of agreement, as set forth in each contract we have with significant clients.

License Fees

We have licensed technology for the extraction of RNA and DNA from FFPE tumor specimens from USC in exchange for royalty fees on revenue generated by use of this technology. These royalties are calculated as a fixed percentage of revenue that we generate from use of the technology licensed from USC. Total license fees due under the royalty agreement to USC were $14,296 and $23,613 for the quarters ended March 31, 2007 and March 31, 2008, respectively. We also maintain a non-exclusive license to use Roche’s polymerase chain reaction (PCR), homogenous PCR, and reverse transcription PCR processes. We pay Roche a fixed percentage royalty fee for revenue that we generate through use of this technology. Royalties due under this agreement totaled $19,527 and $87,390 for the quarters ended March 31, 2007 and March 31, 2008, respectively. These royalties are recorded as a component of cost of revenues in the statements of operations. We are subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing.

Accounts Receivable

We invoice clients as specimens are processed and any other contractual obligations are met. Our contracts with clients typically require payment within 45 days of the date of invoice. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our clients to make required payments. We specifically analyze accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, our clients have primarily been large pharmaceutical companies. As a result, bad debts to date have been minimal.

Income Taxes

We estimate our tax liability through calculations we perform for the determination of our current tax liability, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded in our balance sheets. Our management then assesses the likelihood that deferred tax assets will be recovered in future periods through future operating results. To the extent that we cannot conclude that it is more likely than not that the benefit of such assets will be realized, we establish a valuation allowance to adjust the net carrying value of such assets. The carrying value of our net deferred tax assets assumes that we will be able to generate sufficient future taxable income, based on management’s estimates and assumptions. These estimates and assumptions take into consideration future taxable income and ongoing feasible tax strategies in determining recoverability of such assets. Our valuation allowance is subject to significant change based on management’s estimates of future profitability and the ultimate realization of the deferred tax assets.

Results of Operations

Quarters Ended March 31, 2008 and March 31, 2007

Revenues. Revenues were $1,902,936 for the first quarter ended March 31, 2008, as compared to $1,619,760 for the first quarter ended March 31,2007, an increase of $283,176, or 17.5%. This growth in revenue was due primarily to increased revenues generated under our existing contracts with our pharmaceutical company partners. For the quarter ended March 31, 2008, two of our clients, GSK and Taiho, accounted for approximately 96% of our revenue, as compared to approximately 92 % of our revenue for the quarter ended March 31, 2007.

Cost of Revenues. Cost of revenues for the quarter ended March 31, 2008 were $918,965 as compared to $822,840 for the quarter ended March 31, 2007, an increase of $96,125 or 12%. This increase primarily resulted from an increase in share-based compensation related to stock options issued to employees and consultants of $71,900, which did not exist for the quarter ended March 31, 2007, an increase of $74,540 for laboratory reagents and supplies, a $29,246 increase in personnel related costs, a $77,180 increase in license fees , a $32,344 increase in insurance costs, an increase in equipment depreciation of $29,702 and an increase in business consulting costs of $34,727 and these increases were partially offset by a decrease resulting primarily from a $213,423 reduction in costs for fluorescence in situ hybridization (FISH) and a $47,200 reduction in costs for bioinformatics services.

Research and Development Expenses. Research and development expenses were $603,385 for the quarter ended March 31, 2008, as compared to $320,422 for the same period in 2007, an increase of $282,963 or 88%. This increase resulted primarily from an increase from share-based compensation related to stock options issued to employees and consultants of $55,146, an increase reagents and supplies for research and development of $40,760, an increase in patent costs of $96,898 which were previously accounted for as part of general and administrative expenses, an increase in equipment depreciation costs of $36,702, business travel of $13,506, increased insurance costs of $17,212, increased business consulting costs and honoraria expense associated with our research collaborations of $41,548. We expect research and development expenses to increase as we work to develop additional aspects of our technology and to study diagnostic indicators for various forms of cancer.

General and Administrative Expenses. General and administrative expenses totaled $2,273,474 for the quarter ended March 31, 2008, as compared to $1,263,066 for the comparable period in 2007, an increase of $1,010,408 or 80%. This increase resulted primarily from $564,966 in expenses incurred to operate our laboratory in Scotland which costs did not exist in 2007, expenses incurred for share-based compensation related to stock options issued to employees and consultants of $211,372, an increase in our business consulting expenses of $253,131, which includes marketing costs for our ResponseDX brand and investor relations activities. We expect general and administrative expenses to increase as a result of the need to hire additional administrative personnel and due to higher legal, accounting, compliance and related expenses associated with being a public company.

Interest Income. Interest income was $153,172 for the quarter ended March 31, 2008, compared with $41,676 for the same period in 2007. This $111,496 increase was due to higher average cash balances and higher rates of return during the period ending March 31, 2008.

Interest Expense. Interest expense was $2,876 for the quarter ended March 31, 2008 and $12,250 for the same period in the preceding year. Prior to our public offering, this expense consisted largely of a fixed amount on notes payable from our stockholders. The notes payable and accrued interest related to these notes payable was converted into shares of our common stock upon the closing of our recent public offering. Refer to Liquidity and Capital Resources below for further discussion regarding this matter.

Income Taxes

As of March 31, 2008 and 2007, a full valuation allowance has been recorded for the deferred tax assets since we do not believe the recoverability of the deferred income tax assets in the near future is more likely then not. Accordingly, an income tax provision/benefit has not been recognized during the quarters ended March 31, 2008 and 2007.

Liquidity and Capital Resources

We incurred net losses of $991,503 and $1,724,970 during the quarter ended March 31, 2007 and the quarter ended March 31, 2008, respectively. Since our inception in September 1999, we have incurred cumulative losses and as of March 31, 2008, we had an accumulated deficit of $22,045,161. We expect that our research and development, and general and administrative expenses will continue to increase and, as a result, we will need to generate significant revenues to achieve profitability.

We expect to use our capital to fund research and development and to make capital expenditures to keep pace with the expansion of our research and development programs and to scale up our commercial operations. The amount and timing of actual expenditures may vary significantly depending upon a number of factors, such as the progress of our product development, regulatory requirements, commercialization efforts, and the amount of cash used by operations. We expect that we will continue to generate revenue through our pharmacogenomic testing services business provided to pharmaceutical companies, but these revenues are not guaranteed and are not expected to substantially offset the costs associated with our expansion efforts.

We lease office and laboratory space for our location in Los Angeles under noncancelable operating leases that expire through March 2010. Additionally, in 2007, the Company entered into an agreement to lease office and laboratory space for our operations in Scotland. This is an operating lease which expires in March, 2010. Rent expense for our facilities was $164,746 and $ 75,001 for the quarters ended March 31, 2008 and 2007, respectively. Future minimum lease payments aggregate to approximately $1,370,513 over the next three years through the expiration of the leases in 2010. We also lease 180 sq ft of space at 103 South Carroll Street, Suite 2b, Fredrick, Maryland 21701, for administrative purposes. This lease expires on August 31, 2008.

Comparison of Quarters Ended March 31, 2008 and 2007

As of March 31, 2008, we had $17,534,089 in cash and cash equivalents, working capital of $15,605,388 and an accumulated deficit of $22,045,161.

Cash flows provided by operating activities

During the quarter ended March 31, 2008, the Company generated positive cash flows from operations of $807,247 compared to a negative cash flow of $1,300,539 in operations in the quarter ended March 31, 2007. The main factors for the increase of $2,107,786 are related to a combination of a decrease in receivables, a decrease in prepaid expenses, accounts payable, accrued expenses, accrued payroll, bonus and related liabilities, and deferred revenue.

The decrease in accounts receivable, of $3,280,082, related mainly to one receivable related to an amendment entered into in the fourth quarter of 2007 to the contract with GSK Bio, of $3,059,597, which was received in the first quarter. The Company has not entered into any new agreements in the first quarter that require substantial downpayments prior to services rendered.

In addition, the Company has had a decrease in deferred revenue of $1,322,422 related to an decrease in advance billings to its customers, along with the recognition of $1,735,100 in deferred revenue in the current quarter.

The decrease in prepaid expenses and accrued expenses is related to the completion of the IPO process of which the Company was incurring prepaid IPO costs for the first six months of the year ended December 31, 2007, and were offset against the proceeds of our IPO, in June 2007. The current effect of cash outlays for prepaid expenses is related to the Company’s insurance policies.

The change in accrued expenses from the three months ended March 31, 2007 compared to March 31, 2008 is due to less expenses being incurred as a result of the completion of the IPO process in June 2007, which resulted in one time charges that were reimbursed with the proceeds of the IPO. The consistency related to accounts payable is due to the ability of the Company to pay its payables within 30 days of incurring the charges.

The consistent change in accrued payroll, bonus and related liabilities is due to the payment of year end bonuses granted and accrued as of December 31, 2006 of $500,000 and accrued bonuses of $415,000 as of December 31, 2007, which were all paid in the first quarter of the respective subsequent year.

Cash flows used in investing activities

Net cash used in investing activities was $291,329 for the quarter ended March 31, 2008 and $319,136 for the quarter ended March 31, 2007. This decrease in the use of cash of $6,026 was attributable to reduced need for capital equipment in our laboratories.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Use of Proceeds from Registered Securities; Recent sales of Unregistered Securities

On June 8, 2007 we completed our initial public offering of 3,000,000 shares of our common stock at $7.00 per share. The managing underwriter of our initial public offering was Maxim Group LLC. Net proceeds from the initial public offering after deducting underwriting commissions and fees but before expenses were $18,950,000. On closing of our initial public offering all of our outstanding shares of our preferred stock, including accrued but unpaid dividends, automatically converted into 4,360,467 shares of our common stock and all of our outstanding notes payable, including accrued but unpaid interest, automatically converted into 152,489 shares of our common stock. Both of these conversions were based on the initial public offering price of $7.00.

We expect to use the proceeds from our initial public offering for research and development, business expansion, and working capital and other general purposes. Pending such use, the net proceeds from the offering have been invested in interest-bearing money market accounts. None of the net proceeds from the offering were paid directly or indirectly to any of our directors or officers (or their associates) or persons owning 10% or more of any class of our equity securities or to any other affiliate, other than in the form of wages or salaries, fees and bonuses paid out in the ordinary course of business. We will retain broad discretion over the use of the net proceeds received from our initial public offering. The timing and amount of our actual expenditures may vary significantly depending on a number of factors, including the successful early clinical development of our lead product candidates, cash flows from operations and the anticipated growth of our business. We have incurred the following costs as they relate to our use of proceeds including research and development costs of $1,821,214, business expansion costs primarily related to the set up and operation of our European lab of $1,489,666, and $264,971 of cost to establish investor relations and public relations activities necessary for a public company.
