Overview

EXACT Sciences Corporation is a molecular diagnostics company focused on colorectal cancer. Our non-invasive stool-based DNA (sDNA) screening technology includes proprietary and patented methods that isolate and analyze human DNA present in stool to screen for the presence of colorectal pre-cancer and cancer. We believe that our proprietary methods and technologies have several advantages over other screening options that may ultimately lead to decreased mortality associated with colorectal cancer, which is the third leading cause of cancer death overall, the second leading cause of death from cancers that affect both men and women, and the leading cause of cancer death among non-smokers in the United States.

The American Cancer Society estimates that 80-90 million people in the United States are eligible for colorectal cancer screening. The Company will approach this market opportunity by remaining focused on key priorities. The Company's priorities for 2009 are: 1) product development, 2) clinical trial planning and
3) creating a performance culture. Currently, we license certain of our colorectal cancer screening technologies on an exclusive basis in the U.S. and Canada through December 2010 to Laboratory Corporation of America® Holdings, or LabCorp®. LabCorp has developed and commercially offers a non-invasive stool-based DNA (sDNA) colorectal cancer screening service for the average-risk population, which is based on certain of our technologies.

Our primary goal is to become the market leader for a patient-friendly diagnostic screening product for the early detection of colorectal pre-cancer and cancer. Our strategic roadmap to achieve this goal includes the following key components:

† develop and refine our non-invasive sDNA colorectal pre-cancer and cancer screening test;

†

† advance our product through U.S. Food and Drug Administration, or FDA, clinical trials;

† secure insurance coverage and reimbursement for our product; and

† commercialize an FDA-cleared product that detects colorectal pre-cancer and cancer.

We believe obtaining FDA approval is critical to building broad demand and successful commercialization for our sDNA colorectal cancer screening technologies. In 2009, we intend to focus on further refining our product design to demonstrate the clinical superiority of the test to detect pre-cancer and adenomas while balancing its product attributes to enable ease of commercialization and widespread adoption. Additionally, we intend to finalize plans for clinical trials in 2009-with the goal of confirming our trial protocols with the FDA.

We have generated limited operating revenues since inception and, as of June 30, 2009, we had an accumulated deficit of approximately $178.7 million. Losses have historically resulted from costs incurred in conjunction with research, development and clinical study initiatives; salaries and benefits associated with the hiring of personnel; the initiation of marketing programs; and prior to August 31, 2007, the build-out of our sales infrastructure to support the commercialization of SDNA screening. We expect to continue to incur losses for the next several years, and it is possible we may never achieve profitability.

Recent Developments

Mayo Strategic Licensing Agreement

On June 11, 2009, we entered into a strategic transaction with the MAYO Foundation for Medical Education and Research (MAYO) to obtain a world-wide exclusive license to certain intellectual property. As part of the licensing agreement, we granted MAYO two common stock purchase warrants for 1,000,000 and 250,000 shares of common stock, respectively. We will also make payments to MAYO for up-front fees, fees upon our attainment of certain milestones, and other payments as outlined in the agreement. In addition to the license to intellectual property owned by MAYO, we will receive product development and research and development efforts from MAYO personnel. We determined that the payments made for intellectual property should not be capitalized as the future economic benefit derived from the transactions is uncertain. In addition to such payments, we are obligated to make royalty payments to MAYO on potential future net sales of any products developed from the licensed technology.

New Senior Management Team

Effective April 2, 2009, Jeffrey R. Luber resigned as our President, Chief Executive Officer and member of our board of directors and Charles R. Carelli, Jr. resigned as our Chief Financial Officer.

On March 18, 2009, our board of directors appointed Kevin T. Conroy as President and Chief Executive Officer, effective April 2, 2009. Also on March 18, 2009, based on the recommendation of our corporate governance and nominating committee, the board of directors appointed Mr. Conroy to fill a vacancy on our board. Our board of directors also appointed Maneesh K. Arora as our Senior Vice President and Chief Financial Officer, effective April 2, 2009.

Genzyme Strategic Transaction

In January 2009, we completed a strategic transaction with Genzyme Corporation, pursuant to which we assigned to Genzyme all of our intellectual property applicable to the fields of prenatal and reproductive health and granted Genzyme an irrevocable, perpetual, exclusive, worldwide, fully-paid, royalty-free license to use and sublicense all of our remaining intellectual property in all fields other than colorectal cancer detection and stool-based disease detection. We retained our rights in both the assigned and licensed intellectual property in the fields of colorectal cancer detection and stool-based disease detection. We and Genzyme also agreed to form a joint advisory committee to assist Genzyme in the achievement of product development goals related to the purchased intellectual property and to assist us with our regulatory goals.

Genzyme agreed to pay us an aggregate of $18.5 million, of which $16.65 million was paid at closing and $1.85 million is subject to a holdback by Genzyme to satisfy certain of our potential indemnification obligations. Subject to terms of the strategic agreement, one-half of the holdback amount will be released to us in 12 months and one-half will be released in 18 months. Genzyme also agreed to pay a double-digit royalty to us on income received by Genzyme as a result of any licenses or sublicenses to third parties of the assigned or licensed intellectual property in any field other than prenatal and reproductive health or colorectal cancer detection and stool-based disease detection.

In addition, we sold to Genzyme 3,000,000 shares of our common stock at a per share price of $2.00, for a total purchase price of $6.0 million.

Messrs. Luber and Carelli Severance

In connection with their departures in March 2009, Messrs. Luber and Carelli were entitled to receive severance benefits pursuant to their existing retention agreements, including salary continuation of $472,500 and $287,500, which is equal to eighteen months and fifteen months, respectively, of their base salaries as of the date of termination. On March 31, 2009, we entered into release agreements with Messrs. Luber and Carelli that provided, in exchange for a general release in favor of us, for the accelerated payment of the salary continuation obligations on March 31, 2009. In addition, the release agreements also provided for the repurchase by us of certain options held by Messrs. Luber and Carelli for an aggregate of 804,026 shares of common stock, in lieu of accelerated vesting and an extension of the option exercise period arising from their retention agreements. We paid Messrs. Luber and Carelli approximately $39,000 and $11,000, respectively, to repurchase Mr. Luber's options to purchase 553,333 shares and Mr. Carelli's options to purchase 250,693 shares. The purchase price of the outstanding options represented a 75 percent discount from the estimated fair value of the vested options as of March 31, 2009. Messrs. Luber and Carelli retained options to purchase 80,207 and 43,124 shares respectively at an exercise price of $1.83, following the termination of their employment.

Private Placement Transaction

On June 11, 2009, we completed a private placement transaction pursuant to which we sold 4,315,792 shares of common stock at a per share price of $1.90 for total proceeds of $8.2 million.

Significant Accounting Policies

This management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition and intangible assets. We base our estimates on historical experience and on various other factors that are believed to be appropriate 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 may differ from these estimates under different assumptions or conditions.

The notes to our consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2008 include a summary of the significant accounting policies and methods used in the preparation of our consolidated financial statements. As described below, we believe that that the following accounting policies and judgments are critical to fully understand and evaluate our reported financial results.

Revenue Recognition.

License fees. License fees for the licensing of product rights on initiation of strategic agreements are recorded as deferred revenue upon receipt and recognized as revenue on a straight-line basis over the license period. On June 27, 2007, we entered into an amendment to our exclusive license agreement with LabCorp, or the Second Amendment, that, among other modifications to the terms of the license, extended the exclusive license period from August 2008 to December 2010, subject to carve-outs for certain named organizations. Accordingly, we are amortizing the remaining deferred revenue balance resulting from our license agreement with LabCorp at the time of the Second Amendment ($4.7 million) on a straight-line basis over the remaining exclusive license period, which ends in December 2010.

As more fully described under the heading "Genzyme Strategic Transaction" above, in connection with the Genzyme strategic transaction, we received an up-front payment of $16.65 million on January 27, 2009 in exchange for the assignment and licensing of certain of our intellectual property to Genzyme. Our on-going performance obligations to Genzyme under the Collaboration, License and Purchase Agreement, or the CLP Agreement, including our obligation to deliver certain intellectual property improvements to Genzyme during the initial five year collaboration period, were deemed to be undelivered elements of the CLP Agreement on the date of closing. Accordingly, we deferred the initial $16.65 million in cash received at closing and are amortizing that up-front payment on a straight line basis into revenue over the initial five-year collaboration period ending in January 2014. Receipt of any holdback amounts will similarly

be deferred and amortized on a straight line basis into revenue over the remaining term of the collaboration at the time of receipt.

In addition, Genzyme paid $2.00 per share for the 3.0 million shares purchased from us on January 27, 2009, representing a premium of $0.51 per share above the closing price of the Company's common stock on that date of $1.49 per share. The aggregate premium paid by Genzyme over the closing price of our common stock on the date of the transaction of $1.53 million was deemed to be a part of the total consideration for the CLP Agreement. Accordingly, we deferred the aggregate $1.53 million premium and will amortize that amount on a straight line basis into revenue over the initial five year collaboration period ending in January 2014. We recognized approximately $1.6 million in license fee revenue in connection with the amortization of the up-front payments from Genzyme during the six months ended June 30, 2009.

Product royalty fees. We have licensed certain of our technologies, including improvements to such technologies, on an exclusive basis through December 2010 to LabCorp. LabCorp developed and commercially offered PreGen-Plus, a non-invasive sDNA colorectal cancer screening service for the average-risk population based on our Version 1 technology, from August 2003 through June 2008. In June 2008, LabCorp stopped offering PreGen-Plus. On July 14, 2008, LabCorp began to commercially offer ColoSure, its next generation non-invasive, sDNA testing service for the detection of colorectal cancer in the average-risk population, which is based on certain of our intellectual property. We are entitled to the same royalty and milestone structure on any sales of ColoSure as we were entitled to on sales of PreGen-Plus.

Prior to the effective date of the Second Amendment, our product royalty fees were based on a specified contractual percentage of LabCorp's cash receipts from performing PreGen-Plus tests. Accordingly, we recorded product royalty fees based on this specified percentage of LabCorp's cash receipts, as reported to us each month by LabCorp. Subsequent to the effective date of the Second Amendment, our product royalty fees are based on a specified contractual percentage of LabCorp's net revenues from sales of PreGen-Plus through June 1, 2008, when LabCorp stopped offering PreGen-Plus, and from sales of ColoSure from and after July 2008. Accordingly, subsequent to the effective date of the Second Amendment, we record product royalty fees based on the specified contractual percentage of LabCorp's net revenues from its sales of such colorectal cancer screening tests, as reported to us each month by LabCorp. The current royalty rate is 15%, subject to an increase to 17% in the event that LabCorp achieves a specified significant threshold of annual net revenues from the sales of such colorectal cancer screening tests.

Additionally, as described below under the heading "Critical Accounting Estimate
- Third Party Royalty Obligation," pursuant to the Second Amendment, we are potentially obligated to reimburse LabCorp for certain third-party royalty payments. To the extent we incur liabilities in connection with this provision of the Second Amendment, the accretion of such liabilities will be recorded as a reduction in the product royalty fee line item in our statements of operations.

Other revenue. Revenue from milestone and other performance-based payments is recognized as revenue when the milestone or performance is achieved and collection of the receivable is estimable and probable.

Patent Costs. Patent costs, which have historically consisted of related legal fees, are capitalized as incurred, only if the Company determines that there is some probable future economic benefit derived from the transaction. The capitalized patents are amortized beginning when patents are approved over an estimated useful life of five years. Capitalized patent costs are expensed upon disapproval, upon a decision by the Company to no longer pursue the patent or when the related intellectual property is either sold or deemed to be no longer of value to the Company. During the quarter ended June 30, 2009, the Company determined that the patent costs incurred should not be capitalized as the future economic benefit derived from the transactions was not considered probable. In connection with the Genzyme Strategic Transaction, the Company sold its then-remaining capitalized intellectual property to Genzyme on January 27, 2009, and accordingly, wrote off the remaining unamortized capitalized patent costs at that time.

Stock-Based Compensation. We adopted SFAS No. 123(R) effective January 1, 2006 using the modified prospective transition method. SFAS No. 123(R) requires all stock-based payments to employees, including grants of employee stock options and shares purchased under an employee stock purchase plan (if certain parameters are not met), to be recognized in the financial statements based on their fair values. SFAS No. 123(R) did not change the accounting guidance for share-based payment transactions with parties other than employees provided in SFAS No. 123, as originally issued and EITF 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services.

Critical Accounting Estimate - Third Party Royalty Obligation

Pursuant to the terms of the Second Amendment to our license agreement with LabCorp, we are obligated to reimburse LabCorp for certain third-party royalty payments if LabCorp's third-party royalty rate is greater than a specified royalty rate during the measuring period, as outlined in the table below. During the quarter ended March 31, 2009, we paid LabCorp approximately $1.5 million related to our obligation for the first measurement period, which ended on December 31, 2008. Our future obligation to pay LabCorp pursuant to this provision of the Second Amendment is based on LabCorp's sales volumes of colorectal cancer screening tests using our technology during two separate measurement periods, as defined below. A significant increase in such sales volumes during either measurement period, as compared to historical PreGen-Plus sales volumes, could reduce our potential obligation during such measurement period, while test volumes consistent with historical PreGen-Plus sales levels could result in aggregate future payments to LabCorp totaling up to $2.0 million during the remaining measurement periods. Until LabCorp's sales of colorectal cancer screening tests using our technology increase to a level that would reduce this potential maximum obligation, if ever, we intend to record our estimated obligation under this provision of the Second Amendment as a reduction in the product royalty fee line item in our statements of operations, in accordance with EITF No. 01-09, Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor's Products). Based on sales volumes of PreGen-Plus through June 1, 2008 (when LabCorp ceased selling this service) and anticipated sales volumes of ColoSure, as of June 30, 2009, we have accrued a total of $1.97 million related to the total potential $2.0 million remaining obligation to LabCorp. Amounts included in the table are in thousands.

                                                                       Potential                Potential

Recent Accounting Pronouncements

In May 2009, the Financial Accounting Standards Board issued Statement 165, Subsequent Events, to incorporate the accounting and disclosure requirements for subsequent events into U.S. generally accepted accounting principles. Statement 165 introduces new terminology, defines a date through which management must evaluate subsequent events, and lists the circumstances under which an entity must recognize and disclose events or transactions occurring after the balance-sheet date. The Company adopted Statement 165 as of June 30, 2009, which was the required effective date. The Company evaluated its June 30, 2009 financial statements for subsequent events through August 13, 2009, the date the financial statements were available to be issued. The Company is not aware of any subsequent events which would require recognition or disclosure in the financial statements.

Results of Operations

Revenue. Net revenue is primarily composed of the amortization of up-front technology license fees associated with our amended license agreement with LabCorp and our collaboration, license and purchase agreement with Genzyme. The unamortized LabCorp up-front payment is being amortized on a straight-line basis over the remaining exclusive license period, which ends in December 2010. The unamortized Genzyme up-front payment is being amortized on a straight-line basis over the initial Genzyme collaboration period, which ends in January 2014. While we expect license fee revenue resulting from the amortization of the up-front license payment from LabCorp in 2009 to be consistent with amounts recorded in 2008, we expect that total license fee revenue for 2009 will be higher than amounts recorded in 2008 as a result of amortization of payments received from Genzyme in January 2009 in connection with the Genzyme strategic transaction.

Net revenue increased to $1.3 million for the three months ended June 30, 2009, from ($0.1) million for the same period in 2008 and increased to 2.3 million for the six months ended June 30, 2009 from ($0.1) million for the same period in 2008. The increase in net revenue for the three and six months ended June 30, 2009 when compared to the same periods of 2008, was primarily due to an increase of approximately $0.9 million and $1.6 million, respectively, for

the three and six months ended June 30, 2009 in license fee amortization as a direct result of the commencement of amortization of the upfront payment received from Genzyme in January 2009. In addition, product royalty revenues were higher for the three months and six months ended June 30, 2009 when compared to the same period in 2008 due to product royalty revenue charges of $0.5 million and $0.8 million recorded during the three months and six months ended June 30, 2008. These charges related to our third-party royalty reimbursement obligation to LabCorp, and resulted in negative product royalty revenue for the three and six months ended June 30, 2008.

Research and development expenses. Research and development expenses increased to $2.0 million for the three months ended June 30, 2009 from $0.5 million for the three months ended June 30, 2008, and increased to $2.1 million for the six months ended June 30, 2009 from $1.4 million for the six months ended June 30, 2008. The increase is primarily due to the $1.7 million non-cash charge incurred as a result of the issuance of warrants pursuant to the Mayo licensing agreement and increased research and development efforts.

As a result of the activities anticipated in support of our objectives toward developing an FDA-approved in vitro diagnostic test, we expect research and development costs in 2009 to be higher than 2008 levels.

General and administrative expenses. General and administrative expenses increased to $1.6 million for the three months ended June 30, 2009, compared to $1.5 million for the same period in 2008. The increase is primarily due to a $0.5 million increase in non-cash stock-based compensation expense included in general and administrative expense in the quarter ended June 30, 2009, which was partially offset by a decrease in general operating expenses in the second quarter of 2009 of $0.3 million compared to the prior year period.

General and administrative expenses increased to $6.4 million for the six months ended June 30, 2009, compared to $3.3 million for the same period in 2008. This increase was primarily the result of $1.9 million in transaction costs related to the Genzyme strategic transaction in January 2009, including legal, audit, and investment banking fees as well as approximately $0.8 million in retention bonus payments made to employees pursuant to board-approved retention agreements. In addition, in connection with the departure of Jeffrey R. Luber, our former President and Chief Executive Officer, and Charles R. . . .
