(b) Such [***] royalty rate (the “Average Full Royalty Rate”) will be applied to the cumulative year-to-date Net Sales in any country in which none of the reductions referred to Section 3.3.3 apply;

EXECUTION VERSION

(c) In respect of all other countries, the Average Full Royalty Rate will then be adjusted for each country after taking into account the reductions referred to in Section 3.3.3. Such adjusted Average Full Royalty Rate will then be applied to the cumulative year-to-date Net Sales in such countries; and

(d) The aggregate royalties payable in each Pfizer Quarter will be the sum of the amounts payable under paragraphs (b) and (c) above, less the aggregate amount of royalties previously paid in respect of such year.

3.3.5. Obligation of the Company to Report to and to Notify Pfizer. For so long as Pfizer is obligated to make royalty payments pursuant to the provisions of this Section 3.3, the Company shall furnish to Pfizer, (i) contemporaneous copies of any royalty or sales reports or other related reports issued or otherwise provided in respect of sales of Licensed Products or payments owing by the Company to [***] under the [***] (as the same are given effect under the FSMA-Company Agreement) or to [***] under the [***] (as the same are given effect under the FSMA-Company Agreement), or, if no such amounts are due or payable under such agreements for any Calendar Quarter, a notice to the effect that no such amounts are due or payable, and (ii) a copy of any and all notices which it receives which relate to any payment obligations (including in respect of royalties or milestones), or which involve an actual, potential or threatened dispute or claim relating to a default under, or termination of, [***].

3.4. Reports and Payments.

3.4.1. Cumulative Royalties. The obligation to pay royalties under this Agreement shall be imposed only once with respect to any sale of any Licensed Product.

3.4.2. Royalty Statements and Payments. Within [***] days of the end of each Calendar Quarter, Pfizer shall deliver to Company a report setting forth for the most recently completed Pfizer Quarter, the following information, on a Licensed Product-by-Licensed Product, country-by-country and Territory-wide basis: (a) gross sales (less returns and on-invoice allowances) of each Licensed Product, (b) deductions from gross sales for each Licensed Product, (c) Net Sales of each Licensed Product, (d) the royalty due hereunder for the sale of each such Licensed Product, and (e) any applicable foreign exchange rates.

3.4.3. Taxes and Withholding. It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar tax (“VAT”), which shall be added thereon as applicable. Where VAT is properly added to a payment made under this Agreement, the Party making the payment will pay the amount of VAT only on receipt of a valid tax invoice issued in accordance

EXECUTION VERSION

with the laws and regulations of the country in which the VAT is chargeable. In addition, in the event any payments made by Pfizer pursuant to this Agreement become subject to withholding taxes under the Laws of any jurisdiction or Governmental Authority, Pfizer shall deduct and withhold the amount of such taxes for the account of Company to the extent required by applicable Law; such amounts payable to Company shall be reduced by the amount of taxes deducted and withheld; and Pfizer shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Company an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all amounts deducted and withheld sufficient to enable Company to claim such payment of taxes. Any such withholding taxes required under applicable Law to be paid or withheld shall be an expense of, and borne solely by, Company. Pfizer will provide Company with reasonable assistance to enable Company to recover such taxes as permitted by applicable Law.

3.4.4. Currency. All amounts payable and calculations under this Agreement shall be in United States dollars. As applicable, Net Sales and any royalty deductions shall be converted into United States dollars at the exchange rate used by Pfizer for public financial accounting purposes in accordance with GAAP. If, due to restrictions or prohibitions imposed by national or international authority, payments cannot be made as provided in this Section 3, the Parties shall consult with a view to finding a prompt and acceptable solution, and Pfizer will deal with such monies as Company may lawfully direct so long as any action required to be taken by Pfizer is at no additional out-of-pocket expense to Pfizer.

3.4.5. Record Keeping. Pfizer shall keep and shall cause its Affiliates and Sublicensees to keep books and accounts of record in connection with the sale of Licensed Products, in accordance with GAAP and in sufficient detail to permit accurate determination of all figures necessary for verification of royalties to be paid hereunder. Pfizer and its Affiliates shall maintain such records for a period of at least three (3) years after the end of the Pfizer Year in which they were generated.

3.4.6. Audits. Upon [***] days prior notice from Company, Pfizer shall permit an independent certified public accounting firm of nationally recognized standing selected by Company and reasonably acceptable to Pfizer, to examine, at [***], the relevant books and records of Pfizer and its Affiliates as may be reasonably necessary to verify the amounts reported by Pfizer in accordance with Section 3.4.2 and the payment of royalties hereunder. An examination by Company under this Section 3.4.6 shall occur not more than [***] and shall be limited to the pertinent books and records for [***] before the date of the request. The accounting firm shall be provided access to such books and records at Pfizer’s facility(ies) where such books and records are normally kept and such examination shall be conducted during Pfizer’s normal business hours. Pfizer may require the accounting firm to sign a standard non-disclosure agreement before providing the accounting firm access to Pfizer’s facilities or records. Upon completion of the audit, the accounting firm shall provide both Pfizer and Company a written report disclosing any discrepancies in the reports submitted by Pfizer or the royalties paid, and, in each case, the specific details concerning any discrepancies. No other information shall be provided to Company.

EXECUTION VERSION

3.4.7. Underpayments/Overpayments. If such accounting firm concludes that additional royalties were due to Company, Pfizer shall pay to Company the additional royalties within [***] days of the date Pfizer receives such accountant’s written report plus interest as set forth in Section 3.4.8. If such accounting firm concludes that Pfizer overpaid royalties to Company, Pfizer shall be entitled to offset such amount against payments that thereafter become due hereunder until such amount has been fully recovered by Pfizer. To the extent not offset, Company will refund such overpayments to Pfizer, within [***] days of the date the Company receives such accountant’s report. Additionally, if the amount of any overpayment or underpayment reported in such audit exceeds [***] of the amount that was properly payable by Pfizer, Pfizer shall reimburse Company for all reasonable charges of such accountants for conducting the audit, but only if and to the extent such overpayment or underpayment was not incurred as a result of any errors or omissions in royalty reports or statements or other documents which were provided by Company to Pfizer, including pursuant to Section 3.3.5.

3.4.8. Late Payments. The payments due to Company under this Agreement shall, if overdue, bear interest beginning on the date on which payment was due and until payment thereof at a per annum rate equal to [***] above the prime rate in effect on the due date as reported by The Wall Street Journal, not to exceed the maximum permitted by law. Any such overdue payments when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not preclude Company from exercising any other rights it may have as a consequence of the lateness of any payment.

3.4.9. Confidentiality. All reports and financial information of Pfizer which are provided to or subject to review by Company under this Section 3 shall be deemed to be Pfizer’s Confidential Information subject to the provisions of Section 6, and Company shall not disclose such Confidential Information to any Third Party or use such Confidential Information for any purpose other than verifying payments to be made by Pfizer to Company hereunder.

3.5. Pfizer Right of Setoff. If and to the extent Company fails to timely pay FSMA or any Third Party in respect of any payments due in respect of the Company Intellectual Property licensed to Pfizer under this Agreement [***], then Pfizer may, at its election, after reasonable consultation with Company as and to the extent circumstances permit, but otherwise without notice of its election and without demand, (a) pay such payments to FSMA or such Third Party, and (b) charge and setoff such payments against amounts otherwise due from it or its related entities to the Company under this Agreement, and the Company hereby authorizes all

EXECUTION VERSION

such charges and setoffs. Pfizer’s right of set-off as described in this Section 3.5 shall immediately terminate, without any action required by either Party, if and when Pfizer, Company and FSMA enter into an amendment of the FSMA-Company Agreement providing for the Stand-By Rights. “Stand-By Rights” means FSMA, Company and Pfizer will enter into an agreement: (1) to address payment disputes between Company and FSMA, providing for a mechanism for a single set of payments to be made by Pfizer with respect to the portions of payments provided for and which become due under this Agreement that are to be paid on to FSMA, which payments would be made to Company or FSMA (as mutually agreed by such parties) or to a third party escrow agent (if Company and FSMA cannot reach agreement), while also providing for the appropriate portion of such payments to [***]; (2) provided Pfizer makes such payments when due and Pfizer is otherwise not in material breach of this Agreement, then neither Company nor FSMA would challenge or seek to terminate Pfizer’s license rights under the Company Intellectual Property as granted to Pfizer under this Agreement, and Company and FSMA would resolve their disputes without disturbing Pfizer’s license rights; and (3) in the event that Company’s licenses under the FSMA-Company Agreement are terminated for any reason, then, without any action required by any party, Pfizer will have a direct license from FSMA under terms and conditions no less favorable to Pfizer than those set forth in this Agreement, which license would be at least of the same scope sublicensed to Pfizer hereunder, provided that Pfizer is not in material breach of this Agreement or the agreement between FSMA, Company and Pfizer entered into pursuant to the foregoing.

3.6. No Guarantee of Success.

Company shall reasonably assist Pfizer (at Pfizer’s expense) in any action if so requested, and shall have the right to participate in such defense and be represented by counsel of its own selection at its own expense and shall consent to lend its name to such actions or proceedings if reasonably requested by Pfizer or required by applicable Law. Notwithstanding the foregoing, (i) Pfizer shall consult with Company regarding any statements in any written or oral arguments it intends to make in any such action, and shall not make any such statement which Company or its counsel has reasonably determined would detrimentally affect any Company Patent Right or any other patent or patent application owned or controlled by Company; and (ii) Pfizer shall not agree to any settlement of any such action without the prior written consent of Company, such consent not to be unreasonably withheld or delayed. If Pfizer does not take legal action as is required to defend the validity or enforceability of such Company Patent Rights within [***] following the date on which Pfizer first becomes aware of such third party challenge, Pfizer shall provide at least [***] notice to Company prior to a corresponding deadline, if applicable, and Company may then, at its option, assume control and defense of such action at its expense. In the event that Company assumes control of the defense, Pfizer shall give reasonable assistance (excluding financial assistance) to Company. Pfizer may be represented by counsel of its own selection at its own expense in any such legal action, but Company shall have the right to control the action with counsel of its own choice.

5.4. Recovery. Any consideration paid by a third party as the result of proceedings or other actions (whether by way of settlement or otherwise) undertaken by Pfizer pursuant to Section 5.2 above, shall first be applied to reimbursement of the unreimbursed legal fees and expenses reasonably incurred by Pfizer and then the remainder shall be allocated [***] to Pfizer and [***] to Company.

8.5.1. Effect of Termination.

(a) Termination Generally. Upon termination of this Agreement for any reason, final reports in accordance with Section 3.4 shall be submitted to the Company.

In the event that Company or its sublicensees receives, in any transaction included within the definition of Net Sales, any non-cash compensation or lower prices on other products in exchange for any Licensed Products, or sells Licensed Products in other than an arms-length transaction, then for the purposes of determining Net Sales hereunder the gross amount invoiced in such transaction shall be deemed to be the gross amount that would have been paid had there been such a sale at the average sale price of such Licensed Products during the applicable royalty reporting period in the country in which such disposition took place or, if such amount cannot be determined, the average sales price of such Licensed Products in those countries in which Licensed Products are then being marketed. The preceding sentence shall not apply to the distribution at no cost of Licensed Products to physicians, hospitals or clinics for promotional purposes or academic investigators for research and clinical trial purposes, which are not included in the definition of Net Sales.

except, in each case, to the extent caused by the negligence, recklessness or intentional acts of Company or any Company Indemnified Party and claims for which Company is required to indemnify Pfizer pursuant to Section 9.3.

9.3. Indemnification by Company.

except to the extent caused by the negligence, recklessness or intentional acts of Pfizer or any Pfizer Indemnified Party and claims for which Pfizer is required to indemnify Company pursuant to Section 9.2.

9.4. Procedure.

9.4.1. Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which indemnification may be sought hereunder. In the event that any Third Party asserts a claim or other proceeding (including any governmental investigation) with respect to any matter for which a Party (the “Indemnified Party”) is entitled to indemnification hereunder (a “Third Party Claim”), then the Indemnified Party shall promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

9.4.2. Control. Subject to Pfizer’s right to control any actions described in Section 5 (even where Company is the Indemnifying Party), the Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within [***] after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that (a) the Indemnifying Party has sufficient financial resources, in the reasonable judgment of the Indemnified Party, to satisfy the amount of any adverse monetary judgment that is sought, (b) the Third Party Claim seeks solely monetary damages and (c) the Indemnifying Party expressly agrees in writing that as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy and discharge the Third Party Claim in full (the conditions set forth in clauses (a), (b) and (c) above are collectively referred to as the “Litigation Conditions”). Within [***] after the Indemnifying Party has given notice to the Indemnified Party of its exercise of its right to defend a Third Party

EXECUTION VERSION

Claim, the Indemnified Party shall give notice to the Indemnifying Party of any objection thereto based upon the Litigation Conditions. If the Indemnified Party reasonably so objects, the Indemnified Party shall continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party shall be entitled, at its sole cost and expense, to assume direction and control of such defense, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party shall cooperate, and shall cause its Affiliates and agents to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not satisfy the Litigation Conditions or does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within [***] after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other party is defending as provided in this Agreement.

9.4.3. Settlement. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief, but shall not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages without the prior written consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified Party shall not make any admission of liability in respect of any Third Party Claim without the prior written consent of the other party, and the Indemnified Party shall use reasonable efforts to mitigate Liabilities arising from such Third Party Claim.

9.5. Insurance. Each Party further agrees to obtain and maintain, during the Term, commercial general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers (or pursuant to a program of self-insurance reasonably satisfactory to the other Party) to cover its indemnification obligations under Section 9.2 or Section 9.3, as applicable, [***].

Repligen Announces Licensing Agreement with Pfizer

for Spinal Muscular Atrophy Program

WALTHAM, MA – January 03, 2013 – Repligen Corporation (NASDAQ:RGEN) announced today that it has entered into an exclusive worldwide licensing agreement with Pfizer Inc. to advance Repligen’s spinal muscular atrophy (SMA) program, originally in-licensed from Families of SMA (FSMA). The SMA program includes RG3039, a small molecule drug candidate in clinical development for SMA, as well as backup compounds and enabling technologies. Under the terms of the agreement, Repligen is entitled to receive up to $70 million from Pfizer, commencing with an upfront payment of $5 million and total potential future milestone payments of up to $65 million as well as royalties on any future sales of SMA compounds developed under the agreement. SMA is an orphan neurodegenerative genetic disease that presents early in life.

“This agreement is consistent with the strategic decision we announced in August 2012 to focus Repligen’s internal efforts on the growth of our bioprocessing business, while seeking external partners for our therapeutic development programs,” said ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Ph.D., President and Chief Executive Officer of Repligen. “We believe this collaboration with Pfizer, a leading pharmaceutical company with specialized efforts in orphan and genetic diseases, has the potential to accelerate the development of therapies for SMA.”

“There is a critical need to expedite potential treatment solutions for rare diseases such as spinal muscular atrophy, where patients have such limited options,” said ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇-▇▇▇▇▇, Senior Vice President, Pfizer BioTherapeutics R&D. “This partnership will combine our expert capabilities in advancing molecules for genetic diseases with Repligen’s leading SMA program.”

Under the terms of the agreement, Repligen is responsible for completing the first two cohorts of an active Phase 1 trial evaluating RG3039 in healthy volunteers, which it anticipates will occur during the first quarter of 2013. Repligen will also provide certain technology transfer services to Pfizer who will then assume full responsibility for the SMA program moving forward, including the conduct of any registration trials necessary for product approval. Repligen has previously received U.S. Orphan Drug and Fast Track designations for RG3039 for the treatment of SMA, as well as Orphan Medicinal Product designation in the EU.

“This licensing deal demonstrates the innovative collaborations that Families of SMA has successfully implemented between non-profit, biotech and big pharma,” stated ▇▇▇▇ ▇▇▇▇▇▇▇, Ph.D., Research Director for Families of SMA. “These partnerships are critical for the development of new treatments for an orphan disease such as SMA. We are extremely pleased to see Pfizer taking the lead on the development and commercialization of the SMA program, following Repligen’s development work and FSMA’s original investment.”

Exhibit A-16

EXECUTION VERSION

Families of SMA, a patient organization dedicated to funding research to advance therapies for SMA, funded and directed the preclinical development of RG3039 with an investment of more than $13 million. This was the first drug discovery program ever conducted specifically for SMA. Repligen’s research and clinical efforts, including the current Phase 1b trial, have been partially supported by a $1.4 million grant from the Muscular Dystrophy Association.

About Spinal Muscular Atrophy

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease in which a defect in the SMN1 (survival motor neuron) gene results in low levels of the protein SMN and leads to progressive damage to motor neurons. It is the leading cause of infant mortality and the second most common inherited neuromuscular disease, with symptoms that typically emerge before the age of two. SMA is characterized by progressive muscle weakness leading to severe physical disability and often, early loss of life due to respiratory insufficiency.

About Families of SMA

Families of SMA is the world’s leader focused on funding SMA research to develop a treatment and cure for the disease. The successful results and progress that the organization has delivered, from basic research to drug discovery to clinical trials, provide real hope for families and patients impacted by the disease. The charity has invested over $55 million in research and has been involved in funding half of all the ongoing novel drug programs for SMA. Families of SMA is a nonprofit 501(c)3 organization, with 31 Chapters and 90,000 members and supporters throughout the United States. The organization’s work has produced major discoveries, including identification of the underlying cause and a back-up gene for the disease, which provides a clearly defined target for disease altering therapies. The organization is also dedicated to supporting SMA families through networking, information and services and to improving care for all SMA patients. For more information: ▇▇▇.▇▇▇▇▇▇▇.▇▇▇.

About the Muscular Dystrophy Association

The Muscular Dystrophy Association (MDA) is the leading nonprofit health agency dedicated to finding treatments and cures for more than 40 neuromuscular diseases, including SMA, by funding worldwide research. MDA also funds comprehensive health care and support services, advocacy, information and education, and accessible summer camp for thousands of youngsters fighting progressive muscle diseases. To date, MDA has invested more than $41.6 million in SMA research, funding basic research and clinical trials of therapeutic strategies such as gene-based therapies, small-molecule development, and stem cells. MDA, along with other SMA patient advocacy groups, has been working with policymakers to explore the potential of expanding newborn screening panels to include SMA.
