if there is overlap between any of deductions [**] each individual item shall only be deducted once in each Net Sales calculation.

 

Net Sales calculated as described above shall be adjusted for Combination Products, as provided in Section 4.7.  The same adjustment shall be applied to product bundles (in the countries where bundling is permitted).

 

Net Sales shall, as to any unit of Product, be calculated based on the first sale of such unit of Product by Merrimack or any of its Affiliates, licensees or sublicensees to a Third Party (other than a licensee or sublicensee).

(i)            The payment for Therapeutic Development Milestone 1 shall be reduced to [**] Dollars ($[**] months [**].

 

(ii)           All Therapeutic Development Milestones are payable on a Therapeutic Product-by-Therapeutic Product and Therapeutic Area-by-Therapeutic Area basis for each of the first 4 Therapeutic Areas per Therapeutic Product.  No Therapeutic Development Milestones are due for Therapeutic Areas beyond the fourth Therapeutic Area (i.e., a “[**]” or “[**]” Therapeutic Area, and so on).  Notwithstanding the foregoing, if a Therapeutic

 

11











 

Development Milestone is paid on a Therapeutic Product with respect to a Therapeutic Area, and subsequently further development and/or commercialization of such Therapeutic Product for such Therapeutic Area is abandoned, and following such abandonment Merrimack achieves the same Therapeutic Development Milestone with a different Therapeutic Product for the same Therapeutic Area, such Therapeutic Development Milestone shall not be due with respect to such subsequent milestone achievement.

 

(iii)         For this purpose, all Therapeutic Products [**] shall be considered a [**] Therapeutic Product.  [**].  A [**] Therapeutic Product containing [**] Licensed Antibody shall be considered a [**] Therapeutic Product from [**] that Licensed Antibody and [**] antibodies (whether Licensed Antibodies or otherwise).

 

(iv)          On a Therapeutic Product-by-Therapeutic Product basis:  if Merrimack achieves a Therapeutic Development Milestone event with respect to a “first,” “second,” “third,” or “fourth” Therapeutic Area without having achieved a prior Therapeutic Development Milestone event with respect to such “first,” “second,” “third,” or “fourth”[**]Therapeutic Area as applicable, then Merrimack will make the prior Therapeutic Development Milestone payment together with the payment of the Therapeutic Development Milestone payment for the achieved subsequent milestone event.  For all purposes under this Section, whether a Therapeutic Area is “first,” “second,” “third,” or “fourth” for any given milestone event will be determined not based on which Therapeutic Area started first in development, but rather on which Therapeutic Area first achieves the milestone event. For a non-limiting example, [**].

 

(b)           Diagnostic Development Milestones.  For each Diagnostic Product, Merrimack shall report in writing to Adimab the achievement of each event and pay the corresponding development milestone payment to Adimab (each, a “Diagnostic Development Milestone”), each within [**] days after the achievement of the corresponding Diagnostic Development Milestone event in the following table (whether achieved by or on behalf of Merrimack or its Affiliate or any other entity acting on behalf of any of them or having received a license, sublicense or other rights from any of the foregoing).  If Merrimack requires an invoice for such purposes, it may request one in advance in order to be able to make timely payment.

(ii)           For this purpose, even if a Product contains [**], it shall be considered a [**] for purposes of this Section 4.4.  The principles of Section 4.4(a)(iii) shall apply [**] as they do to [**].

 

4.5          Royalty Payments. Merrimack shall pay Adimab royalties on Net Sales of Therapeutic Products at the rate of [**] percent ([**]%) and royalties on Net Sales of Diagnostic Products at the rate of [**] percent ([**]%), in each case with respect to all Net Sales achieved during the applicable Royalty Term (determined on a country-by-country and Product-by-Product basis in accordance with Section 4.6).

 

4.6          Royalty Term.  “Royalty Term” means, on a Product-by-Product and country-by-country basis, the time from the First Commercial Sale of such Product in such country until the later to occur of (a) the expiration of the last Valid Claim Covering the Product in the country in which such Product is sold, or (b) [**] the [**], on [**] of [**] with [**] to [**] of the [**] in a [**] of the [**] is [**] in the [**].

 

4.7          Combination Products.  If Merrimack, its Affiliate or the Product licensee or sublicensee of any of them sells any Product as a combination product containing one or more active ingredient(s) that are not Licensed Antibody(ies) (whether combined in a single formulation or sold as a bundle of separate formulations) (“Combination Product”), Net Sales for such Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/(A+B) where A is the invoice price of the Licensed Antibody(ies) in such Combination Product if sold separately, and B is the total invoice price of any other active ingredient or ingredients in the combination, if sold separately.  If, on a country-by-country basis, A or B is not available, then (a) Net Sales of such Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction of C/C+D where C is the fair market value of the Licensed Antibody(ies) and D is the fair market value of all other drug product(s) included in the Combination Product and (b) Merrimack shall notify Adimab of its good faith determination of such fair market values and make any applicable royalty payments based on such determination; provided  that, if Adimab disagrees with such good faith determination, Adimab shall notify Merrimack of such disagreement and the Parties shall seek to resolve such disagreement in accordance with Section 10.2; provided  further  that, if the Parties are unable to resolve such disagreement through Senior Executives Discussions, either Party may request that the Parties resolve such dispute by appointing a mutually agreeable Third Party with expertise in commercial pharmaceutical matters to resolve the dispute, in which case the Parties shall appoint such Third Party within [**] days after such request and instruct such Third Party to resolve the dispute as promptly as possible, and any such resolution shall be binding on both Parties.  [**].  Both Parties shall use all reasonable efforts to cause the process to be completed within [**] days after it begins.  The Third Party dispute resolver shall be, and is hereby, instructed to fashion and cause the Parties to follow a procedure that limits discovery, allows written submissions of no more than [**] pages from each Party, and allows a presentation by each Party of their position not to exceed [**] hours (though the Parties’ may respond within time and page limits set by the Third Party to any questions the Third Party may have).

4.9          Royalty Payment Reports.  With respect to each calendar quarter, at the time(s) when the payments of Section 4.8 are due, Merrimack shall provide to Adimab a written report stating the number and description of all Products sold during the relevant calendar quarter; the gross sales associated with such sales; and the calculation of Net Sales on such sales.  The report shall provide all such information on a country-by-country and Product-by-Product basis.

 

4.10        Payment Method.  All payments due under this Agreement to Adimab shall be made by bank wire transfer in immediately available funds to an account designated by Adimab.

Accordingly, if any such taxes are levied on such payments due hereunder (“Withholding Taxes”), Merrimack shall (i) deduct the Withholding Taxes from the payment amount, (ii) pay all applicable Withholding Taxes to the proper taxing authority, and (iii) send evidence of the obligation and payment of such tax to Adimab concurrently with the payment by Merrimack to Adimab of the payment hereunder subject to such Withholding Taxes.

 

4.12        Records; Inspection.

 

(a)           Merrimack shall keep, for a period of [**] years following the end of the calendar year to which such records relate, and ensure that its Affiliates keep, complete and accurate records of its sales of Product including all records that may be necessary for the purposes of calculating all payments due under this Agreement.  Merrimack shall make such records available for inspection by an accounting firm selected by Adimab at Merrimack’s premises in the United States on reasonable notice during regular business hours.

 

(b)           At Adimab’s expense no more than [**] per calendar year, Adimab has the right to retain an independent certified public accountant from a nationally recognized (in the U.S.) accounting firm (that is not an Affiliate of Adimab) to perform on behalf of Adimab an audit, conducted in accordance with GAAP, of such books and records of Merrimack and its Affiliates as are necessary (in the reasonable opinion of the auditor) to verify Net Sales for the period or periods requested by Adimab and the correctness of any report or payments made under this Agreement, and solely for such purpose.  Merrimack may require that such independent accounting firm enter into a confidentiality agreement reasonably satisfactory to Merrimack as a condition to obtaining access to such records.

 

(c)           If the audit reveals an underpayment, Merrimack shall promptly pay to Adimab the amount of such undisputed underpayment plus interest in accordance with Section 4.16.  If the audit reveals that the undisputed monies owed by Merrimack to Adimab has been

If Merrimack grants any Product licenses or sublicenses, the agreements for such licenses and sublicenses shall include an obligation for the sublicensee to (i) maintain, for a period of [**] years following the end of the calendar year to which such records relate, records adequate to document and verify the proper payments to be paid to Adimab hereunder; (ii) provide reports with sufficient information to allow such verification; and (iii) allow Adimab (or Merrimack if requested by Adimab) to verify the payments due (such audit right is not required to be any stronger than that of Section 4.12).  Merrimack may require that any such audit of a licensee or sublicensee be conducted as part of an audit by Merrimack of such licensee or sublicensee, if Merrimack is conducting an audit of the same licensee or sublicensee for the same reporting period(s).

 

4.14        Foreign Exchange.  If any currency conversion shall be required in connection with the calculation of amounts payable hereunder, such conversion shall be made using the average of the exchange rates for the purchase and sale of U.S. dollars, as reported by Bank of America in New York, New York (or its successor entity) on the last business day of the calendar quarter to which such payment pertains.

5.7          Infringement of Patents by Third Parties.

 

(a)           Notification.  Each Party shall promptly notify the other Party in writing if the notifying Party reasonably believes that any Licensed Antibody Program Patent is being or has been infringed or misappropriated by a Third Party (such infringement, together with any that may be imminently threatened to occur by any potential generic version of a Product arising under the implementing procedures of 35 U.S.C. 271(e)(2) or ex-U.S. equivalent, “Infringement”, and “Infringe” shall be interpreted accordingly).

 

(b)           License-Competitive Infringement of Licensed Antibody Program Patents.

 

(i)            First Right.  Merrimack shall have the first right, but not the obligation, to enforce the Licensed Antibody Program Patents against Infringement through [**] (“License-Competitive Infringement”).  Merrimack shall reasonably consider Adimab’s comments on any such enforcement activities.  Except as provided in subsection (d) or in Section 5.8, Merrimack shall bear all costs and expenses for enforcement under this Section 5.7(b)(i) (including the costs of Adimab’s cooperation as required under subsection (e)).

 

(ii)           Back-up Right for License-Competitive Infringement of Licensed Patents.  If Merrimack does not bring action to prevent or abate License-Competitive Infringement within [**] after notification thereof to or by Merrimack pursuant to Section 5.7(a), then Adimab shall have the right, but not the obligation, to bring, at its own expense, an appropriate action against any person or entity engaged in such License-Competitive Infringement directly or contributorily.

With respect to any Infringement of Program Antibody Patents anywhere in the world other than License-Competitive Infringement, Adimab shall have the exclusive right (but not the obligation) to prevent or abate such Infringement, and as between the Parties shall bear all related expenses and retain all related recoveries.  In that case, Adimab shall notify Merrimack of such Infringement and keep Merrimack reasonably informed with respect to the disposition of any action taken in connection with them.

 

(d)           Participation of the other Party with Respect to Infringement Suits.  If a Party brings an action against infringement under this Section 5.7, the other Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, and such Party shall reasonably cooperate with the Party bringing the action, including by joining such suit as a party plaintiff if necessary to obtain standing for such action (all at the expense on a pass-through basis of the enforcing Party).

 

(e)           Settlement.  Adimab shall not settle a claim brought under this Section 5.7 involving Program Antibody Patents in a manner that would limit or restrict the ability of Merrimack to sell Products for use in the Field, or impair the exclusivity of Merrimack’s license rights under this Agreement, or narrow the Licensed Antibody Program Patents or shorten their

6.4          Terms of Agreement.  The terms of this Agreement are the Confidential Information of both Parties.  However, each Party shall be entitled to disclose the terms of this Agreement under legally binding obligations of confidence and limited use to:  legal, financial and investment banking advisors; and potential and actual investors, lenders, acquirors and licensees or sublicensees and counsel for the foregoing.  In addition, if legally required, a copy of this Agreement may be filed by either Party with the SEC (or relevant ex-U.S. counterpart).  In that case, the filing Party will if requested by the other Party diligently seek confidential treatment for terms of this Agreement for which confidential treatment is reasonably available, and shall provide the non-filing Party reasonable advance notice of the terms proposed for redactions and a reasonable opportunity to request that the filing Party make additional redactions to the extent confidential treatment is reasonably available under the law.  Such reasonable opportunity shall include at least [**] weeks to comment in the case of the initial public filing of this Agreement.  [**].

 

6.5          Return of Confidential Information.  Promptly after the termination or expiration of this Agreement for any reason, each Party shall return to the other Party all tangible manifestations of such other Party’s Confidential Information at that time in the possession of the receiving Party.

 

6.6          Publicity.  The Parties have agreed there will not be a press release to announce the execution of this Agreement.  Other than a mutually agreed press release (should the Parties ever agree to one), and other than repeating information in a mutually agreed press release, neither Party will generate or allow any publicity regarding this Agreement or the transaction contemplated hereunder.  Notwithstanding the foregoing, each Party may make such public announcements as may be required in order to comply with applicable securities laws and

 

22











 

regulations, but in this case shall if practicable first confer and seek approval from (i.e., attempt to reach consensus with) the other Party as to what will be said in the disclosure, allowing a reasonable time prior to the disclosure for the other Party to review and for the attempt to reach consensus as to the text of any such required disclosure in advance.  In addition, it is understood and agreed between the Parties that for its marketing purposes Adimab may without disclosing that Merrimack is Adimab’s counterparty under this Agreement or the Target, disclose that this Agreement has been executed, and as success events under this Agreement occur (Research Program and other milestones under this Agreement).

 

6.7          Certain Data.

 

(a)           Notwithstanding this Article 6, without disclosing Merrimack’s identity or the identity of the Program Antibody, other antibodies previously tested by or for Merrimack or the Target (although the class of protein of the Target may be disclosed), Adimab shall be entitled to disclose the following Program Know-How:  (i) [**].

 

(b)           In addition, Merrimack [**] to [**], and [**] to [**] or [**] as [**] by [**] to [**] and [**].  Such data [**] in [**] to [**] by [**].

To be clear, if there is [**] for [**] no data [**] the [**] for data [**] be disclosed pursuant to Section 6.7(a) above.  Further, for the sake of clarity, this Section 6.7 does not [**] to [**] the data for [**] described in Section 6.7(a) or 6.7(b) to [**], and [**] to the extent that it is [**].

 

6.8          Publications.  Merrimack and its Affiliates, licensees and sublicensees shall have the right to publish or present scientific or technical data, results or other information with respect to any Licensed Antibody or Product.  In the event that Merrimack or any of its Affiliates, licensees or sublicensees desires to make any such publication or presentation that would disclose non-public information about a Licensed Antibody or Product, Merrimack shall notify Adimab of such planned publication or presentation at least [**] days (or at least [**] days in the case of abstracts or oral presentations) prior to submission for publication for review by Adimab.  If Adimab notifies Merrimack that such publication or presentation, in Adimab’s reasonable judgment, contains an invention for which Adimab desires to obtain patent protection, Merrimack shall further delay such publication or presentation for a period reasonably sufficient to permit the timely preparation and filing by Adimab of a patent application(s) on any invention disclosed in such publication or presentation (but no more than [**] days from the date of Adimab’s notice thereof).  To avoid doubt, this Section 6.8 shall not be read to permit the disclosure of any Confidential Information of Adimab other than Specific Antibody Information.

TERM.

 

9.1          Term.  The term of this Agreement shall commence on the Effective Date and shall expire upon (a) the expiration of the Option (if it expires unexercised), or (b) if later, on a country-by-country basis on the expiration of the last Royalty Term for a Product in the particular country (and payment of any required payments to Adimab in such country), in each case, unless earlier terminated by a Party as set forth below in this Article 9.

 

9.2          Material Breach.  Either Party may terminate this Agreement for the material breach of this Agreement by the other Party, if such breach remains uncured [**] days following notice from the non-breaching Party to the breaching Party specifying such breach; provided that, with respect to any such material breach of Merrimack’s diligence obligations pursuant to Section 3.4 relating to one or more (but not all) of the Major Regions, if such breach remains uncured [**] days following notice from the non-breaching Party to the breaching Party

 

25

Notwithstanding anything to the contrary in this Section 9.2 above, if the asserted material breach is a payment breach, [**], then this Agreement shall terminate only upon a final determination by a competent court in accordance with Section 10.2 that such a material breach has occurred; and provided that, in the case of a payment breach that is so determined by a competent court to be a basis for termination, this Agreement shall not terminate if, within [**] days after such final determination, Merrimack pays Adimab all amounts held to be owed to Adimab.

SECOND AMENDMENT

 

THIS SECOND AMENDMENT (the “Amendment”) is made as of June 2, 2011 (the “Amendment  Effective Date”), by and between ADIMAB, LLC, a Delaware limited liability company having an address at 16 Cavendish Court, Lebanon, NH 03766 (“Adimab”) and MERRIMACK PHARMACEUTICALS, INC., a Delaware corporation having an address at One Kendall Square, Suite B7201, Cambridge, MA 02139 (“Merrimack”).

 

BACKGROUND

 

1.                                       Adimab and Merrimack are parties to that certain Collaboration Agreement dated November 16, 2009 and first amended April 27, 2010 (“Collaboration Agreement”).

 

2.                                       To avoid any confusion, the original Adimab signatory to the Collaboration Agreement was “Adimab, Inc., a Delaware corporation.”  Effective December 31, 2010, Adimab, Inc., a Delaware corporation merged into Adimab, LLC, a Delaware limited liability company, such that Adimab, LLC is the current Adimab party to the Collaboration Agreement.

 

3.                                       Adimab and Merrimack wish to amend the Collaboration Agreement to provide accommodation to Merrimack on the first Therapeutic Development Milestone event under the Collaboration Agreement.

 

4.                                       Merrimack is the successor to Merrimack Pharmaceuticals, Inc., a Massachusetts corporation.

 

AGREEMENT

 

Adimab and Merrimack hereby agree as follows:

 

1.                                       Initially capitalized terms used but not defined in this Second Amendment shall have the meanings given in the Collaboration Agreement.

 

2.                                       By way of background, the Research Term under the Collaboration Agreement expired on [**], such that the deadline under Section 4.4(a)(i) as originally written for Merrimack to have the right to pay [**] dollars rather than [**] dollars in respect of Therapeutic Development Milestone event 1 (“[**]”) was [**].

 

3.                                       The language in the cell of the milestone table in Section 4.4(a) that is in the righthand column, in the second row (the row for Therapeutic Development Milestone event 1) that reads “[**] Dollars ($[**]), subject to reduction to [**] Dollars as provided in Section 4.4(a)(i)” is hereby amended to read “[**] Dollars ($[**]) subject to reduction as provided in Section 4.4(a)(i).”

 

4.                                       Section 4.4(a)(i) of the Collaboration Agreement is hereby deleted and replaced with the following:

 

“(i)                               The payment for Therapeutic Development Milestone 1 shall be reduced by X, where X is equal to [**] Dollars ($[**]) minus [**] that such Therapeutic Development Milestone 1 is achieved.  A [**] for this purpose shall mean any [**] that is not a [**].  As non-limiting examples:

 











 

[**]

 

For the avoidance of doubt, Merrimack shall not have to pay Adimab more than [**] Dollars ($[**]) in respect of such achievement of Therapeutic Development Milestone 1 under any circumstances.

 

5.                                       This Amendment is being entered into effective as of the same date as that certain Second Collaboration Agreement between the Parties.  The consideration to Adimab, with respect to the accommodations to Merrimack set forth in this Amendment, is contained in that Second Collaboration Agreement.

 

6.                                       There shall be a press release with respect to the existence of the Collaboration Agreement, and the speed with which antibodies discovered are entered into the clinic.  The Parties shall mutually cooperate to mutually agree as to the wording of such an announcement.  Notwithstanding the foregoing, public disclosure shall be permitted in language and on a timeline that at a minimum ensures compliance with Securities and Exchange Commission and other regulations.  Section 6.6 of the Collaboration shall remain otherwise unchanged and this Section 6 shall not be used to interpret or limit either Party’s disclosure rights under Section 6.6 of the Collaboration Agreement.

 

7.                                       The address for the required copy to Adimab’s counsel of written notices under Section 10.8 of the Collaboration Agreement is hereby updated to reflect the following information:

9.                                       Adimab shall be entitled to terminate this Amendment by written notice to Merrimack if Merrimack does not execute and deliver to Adimab, within 2 Business Days after the Amendment Effective Date, the Second Collaboration Agreement for which Adimab is providing its signature alongside Adimab’s signature on this Amendment.

 

10.                                 Article 10 of the Collaboration Agreement applies to this Amendment as if set forth herein in its entirety.
