<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">Merrimack Pharmaceuticals, Inc. (the “Company”) is a biopharmaceutical company discovering, developing and preparing to commercialize innovative medicines consisting of novel therapeutics paired with companion diagnostics. The Company has six novel therapeutic oncology candidates in clinical development (MM-398, MM-121, MM-111, MM-302, MM-151 and MM-141), multiple product candidates in preclinical development and a discovery effort advancing additional candidate medicines. The Company’s discovery and development effort is driven by Network Biology, which is its proprietary systems biology-based approach to biomedical research.</font></p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"> </p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">The Company is subject to risks and uncertainties common to companies in the biopharmaceutical industry, including, but not limited to, its ability to secure additional capital to fund operations, success of clinical trials, development by competitors of new technological innovations, dependence on collaborative arrangements, protection of proprietary technology, compliance with government regulations and dependence on key personnel. Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, infrastructure and extensive compliance reporting capabilities.</font></p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"> </p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">The Company has incurred significant losses and has not generated revenue from commercial sales. The accompanying condensed consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business.</font></p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"> </p>
<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">As of March 31, 2013, the Company had unrestricted cash and cash equivalents and available-for-sale securities of $86.7 million. The Company expects that its existing unrestricted cash and cash equivalents and available-for-sale securities on hand as of March 31, 2013, anticipated interest income, and research and development and manufacturing funding under its license and collaboration agreement with Sanofi related to MM-121 will enable the Company to fund its operating expenses and capital expenditure requirements into 2014.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">The Company may seek additional funding through public or private debt or equity financings, or through existing or new collaboration arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into additional collaborative arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. Arrangements with collaborators or others may require the Company to relinquish rights to certain of its technologies or product candidates. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs or commercialization efforts, which could adversely affect its business prospects.</font></p>

The Company bases estimates and judgments on historical experience and on various other factors that it believes to be reasonable under the circumstances. The significant estimates in these condensed consolidated financial statements include revenue recognition, periods of meaningful use of licensed products, useful lives with respect to long-lived assets and intangibles and the valuation of stock options, convertible preferred stock warrants, contingencies, accrued expenses, intangible assets, goodwill, in-process research and development, derivative liability and tax valuation reserves. The Company’s actual results may differ from these estimates under different assumptions or conditions. The Company evaluates its estimates on an ongoing basis. Changes in estimates are reflected in reported results in the period in which they become known by the Company’s management.</font></p>

To determine whether an other-than-temporary impairment exists, the Company performs an analysis to assess whether it intends to sell, or whether it would more likely than not be required to sell, the security before the expected recovery of the amortized cost basis. Where the Company intends to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is recognized on the statement of comprehensive loss as an other-than-temporary impairment charge. When this is not the case, the Company performs additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where the Company does not expect to receive cash flows, based on using a single best estimate, sufficient to recover the amortized cost basis of a security and amount of the loss recognized in other income (expense).</font></p>

The Company invests cash equivalents and available-for-sale securities in money market funds, U.S. government agencies securities and various corporate debt securities. Credit risk in these securities is reduced as a result of the Company’s investment policy to limit the amount invested in any one issue or any single issuer and to only invest in high credit quality securities.

The principal and accrued interest are convertible into Silver Creek’s next qualifying series of preferred stock at a discount or into Silver Creek’s existing preferred stock upon maturity of the notes on December 31, 2013, whichever occurs first. Upon issuance, the Company determined that the underlying convertible notes represented share-settled debt and the potential conversion of the convertible notes into Silver Creek’s next qualifying series of preferred stock at a discount met the definition of a derivative. The Company estimated the value of the derivative liability issued in connection with the convertible notes payable at $196,000 as of December 31, 2012 and $231,000 as of March 31, 2013. The derivatives are classified as a liability on the Company’s condensed consolidated balance sheet and are remeasured at each reporting period with changes in fair value being recognized in earnings.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">In January 2011, the Company adopted new authoritative guidance on revenue recognition for multiple element arrangements. This guidance, which applies to multiple element arrangements entered into or materially modified on or after January 1, 2011, amends the criteria for separating and allocating consideration in a multiple element arrangement by modifying the fair value requirements for revenue recognition and eliminating the use of the residual method. The fair value of deliverables under the arrangement may be derived using a best estimate of selling price if vendor specific objective evidence and third party evidence are not available. Deliverables under the arrangement will be separate units of accounting provided that a delivered item has value to the customer on a stand-alone basis and if the arrangement does not include a general right of return relative to the delivered item and delivery or performance of the undelivered item is considered probable and substantially in the control of the vendor. The Company also adopted guidance that permits the recognition of revenue contingent upon the achievement of a milestone in its entirety, in the period in which the milestone is achieved, only if the milestone meets certain criteria and is considered to be substantive. The Company did not enter into any significant multiple element arrangements or materially modify any of its existing multiple element arrangements during the year ended December 31, 2012 or the three months ended March 31, 2013. The Company’s existing license and collaboration agreements continue to be accounted for under previously issued revenue recognition guidance for multiple element arrangements and milestone revenue recognition, as described below.</font></p>

If the license was considered to either not have stand-alone value or have stand-alone value but the fair value of any of the undelivered performance obligations could not be determined, the arrangement was accounted for as a single unit of accounting and the license payments and payments for performance obligations were recognized as revenue over the estimated period of when the performance obligations would be performed.</font></p>

The amendments do not change the current requirements for reporting net income or other comprehensive income, but do require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where the net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about these amounts. For public companies, these amendments are effective prospectively for reporting periods beginning after December 15, 2012. There were no amounts reclassified out of accumulated other comprehensive income during the three months ended March 31, 2013.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">On September 30, 2009, the Company entered into a license and collaboration agreement with Sanofi for the development and commercialization of a drug candidate being developed by the Company under the name MM-121. The agreement became effective on November 10, 2009 and Sanofi paid the Company a nonrefundable, noncreditable upfront license fee of $60.0 million. During the years ended 2010 and 2011, the Company received a total of $20.0 million in milestone payments associated with dosing the first patients in Phase 2 clinical trials in breast cancer and non-small cell lung cancer. During the first quarter of 2012, the Company received an additional milestone payment of $5.0 million associated with dosing the first patient in a Phase 2 clinical trial in ovarian cancer. The Company is eligible to receive additional future development, regulatory and sales milestone payments as well as future royalty payments depending on the success of MM-121.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">Under the agreement, Sanofi is responsible for all MM-121 development and manufacturing costs. The Company has the right, but not the obligation, to co-promote MM-121 in the United States and to participate in the development of MM-121 through Phase 2 proof of concept trials. Sanofi reimburses the Company for direct costs incurred in development and compensates the Company for its internal development efforts based on a full time equivalent (“FTE”) rate. Also as part of the agreement, the Company was required to manufacture certain quantities of MM-121 and, at Sanofi’s and the Company’s option, may continue to manufacture additional quantities of MM-121 in the future. Sanofi reimburses the Company for direct costs incurred in manufacturing and compensates the Company for its internal manufacturing efforts based on an FTE rate. The Company satisfied its manufacturing obligations during 2010 and has elected to continue to manufacture quantities of MM-121.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">The Company applied revenue recognition guidance to determine whether the performance obligations under this collaboration, including the license, the right to future technology, back-up compounds, participation on steering committees, development services and manufacturing services, could be accounted for separately or as a single unit of accounting. The Company determined that its development services performance obligation is considered a separate unit of accounting, as it is set at the Company’s option, has stand-alone value and the FTE rate is considered fair value. Therefore, the Company recognizes cost reimbursements for MM-121 development services as incurred. The Company determined that the license, the right to future technology, back-up compounds, participation on steering committees and manufacturing services performance obligations represented a single unit of accounting. As the Company cannot reasonably estimate its level of effort over the collaboration, the Company recognizes revenue from the upfront payment, milestone payment and manufacturing services payments using the contingency-adjusted performance model over the expected development period, which is currently estimated to be 12 years from the effective date of the agreement. Under this model, when a milestone is earned or manufacturing services are rendered and product is delivered, revenue is immediately recognized on a pro-rata basis in the period the milestone was achieved or product was delivered based on the time elapsed from the effective date of the agreement. Thereafter, the remaining portion is recognized on a straight-line basis over the remaining development period.</font></p>

Fair value is determined based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect certain market assumptions. As a basis for considering such assumptions, GAAP establishes a three-tier value hierarchy, which prioritizes the inputs used to develop the assumptions and for measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets for identical assets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.</font></p>

However, if the Company receives aggregate gross proceeds of at least $75 million in one or more transactions prior to December 1, 2013, the Company may elect to extend the interest-only period by six months so that the aggregate outstanding principal balance of the loans would be repaid in monthly installments starting on June 1, 2014 and continuing through November 1, 2016. For the three months ended March 31, 2013, interest expense related to the outstanding principal balance of the loans was $1.1 million. Upon full repayment or maturity of the loans, the Company is required to pay a fee of $1.2 million, which is recorded as a long-term liability on the condensed consolidated balance sheets.</font></p>

In exchange for these incentives, the Company pledged to hire an incremental 20 employees and to maintain the additional headcount through at least December 31, 2017. Failure to do so could result in the Company being required to repay some or all of these incentives. The Company has deferred and will amortize the benefit of this monetization on a straight-line basis over the five-year performance period, commencing with a cumulative catch-up when the pledge is achieved.</font></p>

To determine whether an other-than-temporary impairment exists, the Company performs an analysis to assess whether it intends to sell, or whether it would more likely than not be required to sell, the security before the expected recovery of the amortized cost basis. Where the Company intends to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is recognized on the statement of comprehensive loss as an other-than-temporary impairment charge. When this is not the case, the Company performs additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where the Company does not expect to receive cash flows, based on using a single best estimate, sufficient to recover the amortized cost basis of a security and amount of the loss recognized in other income (expense).</font></p>

The principal and accrued interest are convertible into Silver Creek’s next qualifying series of preferred stock at a discount or into Silver Creek’s existing preferred stock upon maturity of the notes on December 31, 2013, whichever occurs first. Upon issuance, the Company determined that the underlying convertible notes represented share-settled debt and the potential conversion of the convertible notes into Silver Creek’s next qualifying series of preferred stock at a discount met the definition of a derivative. The Company estimated the value of the derivative liability issued in connection with the convertible notes payable at $196,000 as of December 31, 2012 and $231,000 as of March 31, 2013.

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">In January 2011, the Company adopted new authoritative guidance on revenue recognition for multiple element arrangements. This guidance, which applies to multiple element arrangements entered into or materially modified on or after January 1, 2011, amends the criteria for separating and allocating consideration in a multiple element arrangement by modifying the fair value requirements for revenue recognition and eliminating the use of the residual method. The fair value of deliverables under the arrangement may be derived using a best estimate of selling price if vendor specific objective evidence and third party evidence are not available. Deliverables under the arrangement will be separate units of accounting provided that a delivered item has value to the customer on a stand-alone basis and if the arrangement does not include a general right of return relative to the delivered item and delivery or performance of the undelivered item is considered probable and substantially in the control of the vendor. The Company also adopted guidance that permits the recognition of revenue contingent upon the achievement of a milestone in its entirety, in the period in which the milestone is achieved, only if the milestone meets certain criteria and is considered to be substantive. The Company did not enter into any significant multiple element arrangements or materially modify any of its existing multiple element arrangements during the year ended December 31, 2012 or the three months ended March 31, 2013. The Company’s existing license and collaboration agreements continue to be accounted for under previously issued revenue recognition guidance for multiple element arrangements and milestone revenue recognition, as described below.</font></p>

If the license was considered to either not have stand-alone value or have stand-alone value but the fair value of any of the undelivered performance obligations could not be determined, the arrangement was accounted for as a single unit of accounting and the license payments and payments for performance obligations were recognized as revenue over the estimated period of when the performance obligations would be performed.</font></p>

<p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2">In February 2013, the Financial Accounting Standards Board issued amendments to the accounting guidance for presentation of comprehensive income to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income, but do require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where the net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about these amounts. For public companies, these amendments are effective prospectively for reporting periods beginning after December 15, 2012. There were no amounts reclassified out of accumulated other comprehensive income during the three months ended March 31, 2013.</font></p>
