​

There shall be no double counting in determining the foregoing deductions from gross amounts invoiced to calculate “Net Sales” hereunder. The calculations set forth in this definition shall be determined in accordance with Accounting Standards.

If non-monetary consideration is received by a Selling Party for any Licensed Product in a relevant country, Net Sales will be calculated based on the average price charged for such Licensed Product during the preceding royalty period, or, in the absence of such sales, the fair market value of the Licensed Product as determined by Astria in good faith.

Notwithstanding anything to the contrary in this definition, Net Sales will not include transfers of Licensed Products for use in Clinical Trials, non-clinical Development activities, or other Development activities with respect to Licensed Products, for bona fide charitable purposes, for compassionate use or named patient sales, or for Licensed Product samples, if provided at or below cost.

Net Sales shall be determined on, and only on, the first sale by a Selling Party to a non-Selling Party Third Party.

If a Licensed Product is sold as part of a Combination Product (as defined below), Net Sales will be the product of (i) Net Sales of the Combination Product calculated as above (i.e., calculated as for a non-Combination Product) and (ii) the fraction (A/(A+B)), where:

“A” is the gross invoice price in such country of the Licensed Product that is part of such Combination Product when sold without any other therapeutically active ingredients; and

“B” is the gross invoice price in such country of the other therapeutically active ingredients contained in the Combination Product.

If “A” or “B” cannot be determined by reference to non-Combination Product sales as described above, then Net Sales will be calculated as above, but the gross invoice price(s) in the above equation shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on an equitable method of determining the same that takes into account, in the applicable country, variation in dosage units, and the relative fair market value of each therapeutically active ingredient in the Combination Product.

As used in this definition of “Net Sales,” “Combination Product” means a Licensed Product that is sold for a single price with (a) one or more additional active ingredients (whether co-formulated or co-packaged) that are not Licensed Products or (b) any delivery device (e.g., any autoinjector or on-body delivery device or system).

Section 6.6Tax Matters.

(a)Withholding Taxes. Except as expressly set forth in this Section 6.6, each Party shall pay any and all taxes levied on account of all payments it receives under this Agreement. Each Party shall provide such information and documentation to the other Party as are reasonably requested by such other Party to determine if any withholding taxes apply to any payments to be made by such other Party under this Agreement and to establish qualification for a reduced withholding rate or an exemption from such withholding tax under an applicable bilateral income tax treaty or relevant statutory provision. If a Party believes that it is required to withhold taxes on a payment to the other Party, the paying Party shall notify the other Party of such determination no less than [**] prior to making such payment. To the extent that Applicable Laws require that taxes be withheld with respect to any payments to be made by a Party to the other Party under this Agreement, the paying Party shall: (i) deduct those taxes from the remittable payment, (ii) pay the taxes to the proper taxing authority, and (iii) promptly send evidence of the obligation together with proof of tax payment to the other Party on a reasonable and timely basis following such tax payment. Each Party agrees to cooperate with the other Party in claiming refunds, reductions, or exemptions from such deductions or withholdings under any relevant agreement or treaty that is in effect. Notwithstanding anything to the contrary in this Agreement, in the event a Party redomiciles or assigns its rights or obligations under this Agreement in accordance with Section 12.3 (each, a “Tax Action,” and such Party, the “Acting Party”), and, as a result of such Tax Action, the amount of tax required to be withheld under this Section 6.6(a) in respect of a payment to the other Party (the “Non-Acting Party”) is greater than the amount of such tax that would have been required to have been withheld absent such Tax Action, then any such amount payable to the Non-Acting Party shall be adjusted to take into account such withholding taxes as may be necessary so that, after making all required withholdings or credits, the Non-Acting Party receives an amount equal to the sum it would have received, taking into account applicable tax rates imposed on such income and any tax credits available as a result of the

​

- 22 -

​

withholding or credits, had no such Tax Action occurred (but in no case shall any payment under this Agreement be an amount less than the remittable payment due without regard to this Section 6.6). The obligation to adjust payments pursuant to the preceding sentence shall not apply, however, to the extent such increased withholding tax (A) would not have been imposed but for a Tax Action taken by the Party receiving the payment subject to withholding under this Section 6.6(a) or (B) is attributable to the failure by the Non-Acting Party to comply with the requirements of this Section 6.6(a). For purposes of this Section 6.6(a), a “redomiciliation” shall include a reincorporation or other action resulting in a change in tax residence of the applicable Party or its assignee.

(b)Tax Documentation. Each Party has provided a properly completed and duly executed IRS Form W-9 or applicable Form W-8 to the other Party. Each Party shall provide to the other Party, at the time or times reasonably requested by such other Party or as required by Applicable Law, such properly completed and duly executed documentation (for example, IRS Forms W-8 or W-9) as will permit payments made under this Agreement to be made without, or at a reduced rate of, withholding for taxes, and the applicable payment shall be made without (or at a reduced rate of) withholding to the extent permitted by such documentation, as reasonably determined by the paying Party.

Section 6.7Foreign Derived Intangible Income Deduction. Each Party shall use commercially reasonable efforts to provide, and to cause its Affiliates, subcontractors, (sub)licensees, customers, and applicable Third Parties to provide, any information and documentation reasonably requested by the other Party to obtain the benefits of Section 250 of the Internal Revenue Code of 1986, as amended and the applicable Treasury Regulations, including information required to demonstrate the extent to which the Licensed Products will be sold, consumed, used, or manufactured outside the United States.

Section 6.8Currency Exchange. Unless otherwise expressly stated in this Agreement, all amounts specified in, and all payments made under, this Agreement shall be in United States Dollars. If any currency conversion shall be required in connection with the calculation of amounts payable under this Agreement, such conversion shall be performed in a manner consistent with the paying Party’s normal practices used to prepare its audited financial statements for internal and external reporting purposes.

Section 6.9Late Payments. Any payments that are not paid on or before the date such payments are due under this Agreement shall bear interest at an annual rate equal to the lesser of (a) the “prime rate” as reported by The Wall Street Journal, plus [**] percent ([**]%), or (b) the highest rate permitted by Applicable Law; in each case calculated on the number of days such payment is delinquent, compounded monthly; except that, with respect to any disputed payments, no interest payment shall be due until such dispute is resolved and the interest which shall be payable thereon shall be based on the finally-resolved amount of such payment, calculated from the original date on which the disputed payment was due through the date on which payment is actually made.

Section 6.10Blocked Payments. In the event that, by reason of Applicable Law in any country, it becomes impossible or illegal for a Party (or any of its Affiliates or (sub)licensees) to transfer, or have transferred on its behalf, payments owed to the other Party hereunder, such paying

​

- 23 -

​

Party will promptly notify the other Party of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country to the credit of such other Party in a recognized banking institution designated by such other Party or, if none is designated by such other Party within a period of [**], in a recognized banking institution selected by the paying Party or its Affiliate or its (sub)licensee, as the case may be, and identified in a written notice given to such other Party.

Section 6.11Prohibitions on Payments.

Article VII

Intellectual Property

Section 7.1Ownership of Know-How and Patents. As between the Parties, Ichnos will retain all right, title, and interest in and to all Licensed Intellectual Property, except to the extent that any such rights are expressly licensed by Ichnos to Astria under this Agreement, and Astria will retain all right, title, and interest in and to all Patents and Know-How owned or controlled by Astria. With respect to any invention, whether or not patentable, that is conceived or discovered by or on behalf of any Party or any of its respective Affiliates, whether solely or jointly with the other Party, any Affiliate of either Party, or any Third Party, in the course of activities under this Agreement, ownership shall follow inventorship, as determined in accordance with the rules of inventorship under United States patent Laws.

Section 7.2Prosecution of Patents.

(a)Sole and First Prosecution Rights. As between the Parties, Astria will have the first right (but not the obligation) to Prosecute each Licensed Patent at Astria’s sole expense. Ichnos shall as promptly as practicable (but in no event later than [**] after the Effective Date) transition all Prosecution responsibilities to Astria with respect to each Licensed Patent, including execution of such documents as may be necessary to effect such transition. In furtherance of the foregoing, Ichnos will instruct its patent counsel to transition all Prosecution documents relating to the Licensed Patents to Astria’s patent counsel, and will otherwise provide reasonable assistance to Astria and cooperate with Astria to effectuate such transition. After such transition, Astria shall (i) keep Ichnos informed as to material developments with respect to the Prosecution of the Licensed Patents, including by providing copies of all substantive office actions or any other substantive documents in connection with the Licensed Patents that Astria receives from any patent office, and (ii) provide Ichnos with a reasonable opportunity to comment substantively on the Prosecution of the Licensed Patents prior to taking material actions (including the filing of initial applications) with respect to the Licensed Patents, and will consider in good faith any comments made, and actions recommended, by Ichnos with respect thereto, as long as Ichnos does so promptly and consistently with any applicable filing deadlines.

​

- 24 -

​

(b)Step-In Right. If Astria decides not to Prosecute any Licensed Patent in any country in the Territory, or if Astria intends to allow any such Patent to lapse or become abandoned without having first filed a substitute, it shall notify Ichnos of, and consult with Ichnos regarding, such decision or intention at least [**] prior to the date upon which the subject matter of such Patent shall become unpatentable or shall lapse or become abandoned, and Ichnos shall thereupon have the right (but not the obligation) to assume the Prosecution thereof at Ichnos’ own expense with counsel of its choice. Astria shall provide reasonable assistance to Ichnos, and shall cooperate with Ichnos, in connection with the transition of Prosecution responsibilities under this Section 7.2(b), including execution of such documents as may be necessary to effect such transition. Following such transition for a given Patent, Ichnos shall (i) keep Astria informed as to material developments with respect to the Prosecution of such Patent, including by providing copies of all substantive office actions or any other substantive documents in connection with such Patent that Ichnos receives from any patent office, and (ii) provide Astria with a reasonable opportunity to comment substantively on the Prosecution of such Patent prior to taking material actions (including the filing of initial applications) with respect to such Patent, and will consider in good faith any comments made, and actions recommended, by Astria with respect thereto, as long as Astria does so promptly and consistently with any applicable filing deadlines.

Section 7.3Third Party Infringement.

(a)Notice. Each Party shall immediately provide the other Party with written notice reasonably detailing any (i) known or alleged infringement of any Licensed Patent, or known or alleged misappropriation of any Licensed Know-How, by any Third Party in a manner that is, or could reasonably be expected to be, competitive with any Licensed Product, or (ii) declaratory judgment or similar action alleging invalidity, unenforceability, or non-infringement of any Licensed Patent that could reasonably be expected to have a material effect on the Patent protection of any Licensed Product (collectively “Third Party Infringement”).

(b)First Right to Initiate Actions. Astria shall have the initial right, but not the obligation, to initiate a suit or take other appropriate action that Astria believes is reasonably required to enforce or protect any Licensed Patent against any Third Party Infringement. Astria shall give Ichnos advance notice of Astria’s intent to file any such suit or take any such action and the reasons therefor, and shall provide Ichnos with an opportunity to make suggestions and comments regarding such suit or action. Thereafter, Astria shall keep Ichnos reasonably informed regarding the status of any such suit or action.

(c)Step-in Right. If Astria fails to initiate a suit or take such other appropriate action under Section 7.3(b) above with respect to any Third Party Infringement in a reasonable period of time prior to any deadline on which initiation of a suit or other appropriate action is required to avoid limiting or compromising any remedies (including monetary relief and stay of regulatory approval) that may be available against the applicable alleged Third Party infringer, then Ichnos may, in its discretion, provide Astria with written notice of its intent to initiate a suit or take other appropriate action to combat such Third Party Infringement. If Ichnos provides such notice, then Ichnos shall have the right, but not the obligation, to initiate a suit or take other appropriate action that it believes is reasonably required to protect the applicable Licensed Patent from such Third Party Infringement. Ichnos shall give Astria advance notice of its intent to file any such suit or take any such action and the reasons therefor and shall provide Astria with an

​

- 25 -

​

opportunity to make suggestions and comments regarding such suit or action, which Ichnos shall consider in good faith. Thereafter, Ichnos shall keep Astria reasonably informed regarding the status of such suit or action.

(d)Conduct of Action; Costs. The Party initiating any suit under this Section 7.3 shall have the sole and exclusive right to select counsel for such suit; except that such counsel must be reasonably acceptable to the other Party. If required under Applicable Law in order for such Party to initiate or maintain such suit, the other Party shall join as a party to the suit. If requested by the Party initiating suit, the other Party shall provide reasonable assistance to the Party initiating suit in connection therewith, and the initiating Party shall reimburse the other Party for all reasonable Out-of-Pocket Costs (including its reasonable outside counsel expenses) incurred in rendering such assistance. The Party initiating suit shall assume and pay all of its own Out-of-Pocket Costs incurred in connection with any litigation or proceedings described in this Section 7.3, including the fees and expenses of the counsel selected by it. The other Party shall have the right to participate and be represented in any such suit by its own counsel at its own expense.

(e)Recoveries. Any recovery obtained as a result of any proceeding described in this Section 7.3 or from any counterclaim or similar claim asserted in a proceeding described in Section 7.4, by settlement or otherwise, shall be applied in the following order of priority:

(i)first, the Parties shall be reimbursed for all previously unreimbursed Out-of-Pocket Costs in connection with such proceeding; and

(ii)second, any remainder [**].

Section 7.4Claimed Invalidity. If any Third Party at any time asserts any claim that any issued Licensed Patent is invalid or otherwise unenforceable, or if any such Patent is the subject of any pre-grant proceeding or post-grant proceeding (e.g., inter partes review, post grant review, European opposition proceeding) (each, an “Invalidity Claim”), then Astria shall have the first right (but not the obligation) to control the defense and settlement of such Invalidity Claim; except that, if such Invalidity Claim is brought in an infringement action brought by Ichnos pursuant to Section 7.3(c), then Ichnos shall have the right to control the defense and settlement of such Invalidity Claim.

Section 7.5Patent Term Extensions. Astria will have the sole and exclusive right to select the appropriate Patents for filing to obtain patent term extensions, including supplementary protection certificates and any other extensions that are now available or become available in the future, based on Regulatory Approvals for Licensed Products in the Field in the Territory. Ichnos will cooperate with Astria in gaining any such patent term extensions with respect to any Licensed Patent, including by signing all necessary papers.

(a)any breach by Astria of this Agreement;

(b)any negligence, willful misconduct, or violation of Law of Astria or any of its Affiliates or Sublicensees in connection with Astria’s performance of its obligations or exercise of its rights under this Agreement; or

Section 10.3Indemnification Procedures.

(a)General. Promptly after the receipt by a Person seeking indemnification under this Article X (the “Indemnitee”) of notice of any pending or threatened Claim for which the Indemnitee intends to seek indemnification under this Article X, such Indemnitee shall promptly provide notice thereof to the Party from whom indemnification is sought (the “Indemnitor”), which notice shall include a reasonable identification of the alleged facts giving rise to such Claim. Any failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Agreement, except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice. The Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to control the defense and settlement of the indemnified Claim with counsel selected by the Indemnitor. However, notwithstanding the foregoing, the Indemnitee shall have the right to participate in, but not control, the defense of any indemnified Claim, and request separate counsel, with the fees and expenses to be paid by the Indemnitee, unless (a) representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other parties represented by such counsel in such proceedings or (b) the Indemnitor has failed to assume the defense of the applicable Claim, in which case ((a) or (b)), such fees and expenses shall be paid by the Indemnitor. The Indemnitee shall, and shall cause each of its Affiliates and its and their respective directors, officers, employees, agents, successors, and assigns, as applicable, to, cooperate in the defense of any indemnified Claim and shall furnish such records, information, and testimony, provide such witnesses, and attend such conferences, discovery proceedings, hearings, trials, and appeals, and otherwise provide reasonable access to such indemnitees and other employees and agents of the Indemnitee, in each case as may be reasonably requested in connection therewith. The Indemnitor shall reimburse the Indemnitee for its reasonable and verifiable out-of-pocket expenses in connection therewith. The Indemnitor may not settle any Claim, and the Indemnitee shall not be responsible for or be bound by any settlement of a Claim that imposes an obligation on it, without the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld, conditioned, or delayed), unless such settlement or compromise (i) fully releases the Indemnitee without any liability, loss, cost, or obligation, (ii) admits no liability, wrongdoing, or other admission against interest on the part of the Indemnitee, and (iii) would not have an adverse effect on the Indemnitee’s interests (including any rights under this Agreement or the scope or enforceability of the intellectual property licensed hereunder).

(b)No Acknowledgment. The assumption of the defense of a Claim by the Indemnitor shall not be construed as an acknowledgment that the Indemnitor is liable to indemnify the Indemnitee in respect of the Claim, nor shall it constitute a waiver by the Indemnitor of any defenses it may assert against the Indemnitee’s claim for indemnification.

Section 10.4Limitation of Liability. EXCEPT WITH RESPECT TO A BREACH OF ARTICLE VIII, OR A PARTY’S LIABILITY PURSUANT TO SECTION 10.1 OR SECTION 10.2, NEITHER PARTY SHALL BE LIABLE FOR ANY SPECIAL, CONSEQUENTIAL, EXEMPLARY, PUNITIVE, MULTIPLE, OR OTHER INDIRECT OR REMOTE DAMAGES, OR FOR LOSS OF PROFITS, LOSS OF DATA, OR LOSS OF USE DAMAGES ARISING IN ANY WAY OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, WHETHER BASED UPON WARRANTY, CONTRACT, TORT, STRICT

(c)Unless otherwise agreed by the Parties, a dispute between the Parties relating to the validity or enforceability of any Patent will not be subject to arbitration, but will instead be submitted to a court or patent office of competent jurisdiction in the relevant country or jurisdiction in which such Patent was issued or, if not issued, in which the underlying patent application was filed.

Section 12.2Governing Law. This Agreement and all questions regarding its validity or interpretation, or the performance or breach of this Agreement, shall be governed by and construed and enforced in accordance with the laws of the State of New York, without reference to conflicts of laws principles thereof that may dictate application of the laws of any other jurisdiction.

Section 12.3Assignment.

(a)Generally. Neither this Agreement nor any of the rights, interests, or obligations hereunder shall be assigned by either Party (whether by operation of law or otherwise) without the prior written consent of the other Party. Notwithstanding the foregoing, either Party may, without the other Party’s written consent, assign this Agreement in its entirety to (i) an Affiliate of such Party or (ii) a Third Party that acquires, by or otherwise in connection with, merger, sale of assets, or otherwise, all or substantially all of the business of the assigning Party to

​

- 37 -

​

which the subject matter of this Agreement relates, as long as the assignee agrees in writing to assume all of the assigning Party’s obligations under this Agreement. The assigning Party will remain responsible for the performance by its assignee of this Agreement or any obligations hereunder so assigned.

(b)All Other Assignments Null and Void. The terms of this Agreement will be binding upon and will inure to the benefit of the successors, heirs, administrators, and permitted assigns of the Parties. Any purported assignment in violation of this Section 12.3 will be null and void ab initio.

(c)Change of Control.

Section 12.4Force Majeure. If the performance of any part of this Agreement by a Party is prevented, restricted, interfered with, or delayed by a Force Majeure Event, such Party shall, upon giving written notice to the other Party, be excused from such performance to the extent of such prevention, restriction, interference, or delay. However, the affected Party shall use its commercially reasonable efforts to avoid or remove such causes of non-performance and shall continue performance with the utmost dispatch whenever such causes are removed.

Section 12.5Notices. Unless otherwise agreed by the Parties or specified in this Agreement, all notices required or permitted to be given under this Agreement shall be in writing and shall be sufficient if: (a) personally delivered; (b) sent by registered or certified mail (return receipt requested and postage prepaid); or (c) sent by express courier service providing evidence of receipt and postage prepaid where applicable, in each case to the address for a Party set forth below, or such other address for a Party as may be specified in writing by like notice:

​

​

- 38 -

​

​

Any such notices shall be effective upon receipt by the Party to whom it is addressed.

Section 12.6Waiver. Except as otherwise expressly provided in this Agreement, any term of this Agreement may be waived only by a written instrument executed by a duly authorized representative of the Party waiving compliance. The delay or failure of any Party at any time to require performance of any provision of this Agreement shall in no manner affect such Party’s rights at a later time to thereafter enforce such provision. No waiver by any Party of any condition or term in any one or more instances shall be construed as a further or continuing waiver of such condition or term or of another condition or term.

Section 12.7Severability. If any provision of this Agreement should be invalid, illegal, or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal, and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions of this Agreement shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. If the Parties cannot agree upon a substitute provision, the invalid, illegal, or unenforceable provision of this Agreement shall not affect the validity of this Agreement as a whole, unless the invalid, illegal, or unenforceable provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid, illegal, or unenforceable provision.

Section 12.8Entire Agreement. This Agreement (including the Exhibits and Schedules attached hereto) constitutes the entire agreement between the Parties relating to its subject matter, and supersedes all prior and contemporaneous agreements, representations, or understandings, either written or oral, between the Parties with respect to such subject matter, including the Confidentiality Agreement. There are no covenants, promises, agreements, warranties, representations, conditions, or understandings, either oral or written, between the Parties with respect to such subject matter other than as set forth herein.

Section 12.9Modification. No modification, amendment, or addition to this Agreement, or any provision hereof, shall be effective unless reduced to writing and signed by a duly authorized representative of each Party. No provision of this Agreement shall be varied, contradicted, or explained by any oral agreement, course of dealing or performance, or any other matter not set forth in an agreement in writing and signed by a duly authorized representative of each Party.

Section 12.10Independent Contractors; No Intended Third Party Beneficiaries. Nothing contained in this Agreement is intended or shall be deemed or construed to create any relationship of employer and employee, agent and principal, partnership, or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either directly or indirectly, any liability of or for the other Party. Neither Party shall have any express or implied right or authority to assume or create any obligations on behalf of, or in the name of, the other Party, nor to bind the other Party to any contract, agreement or undertaking with any Third Party. There are no express or implied third party beneficiaries hereunder.

Section 12.11Interpretation; Construction. The captions to the several Articles and Sections of this Agreement are included only for convenience of reference and shall not in any way affect the construction of, or be taken into consideration in interpreting, this Agreement. In this Agreement, unless the context requires otherwise, (a) the words “including,” “include,” “includes,” “such as” and “e.g.” shall be deemed to be followed by the phrase “without limitation” or like expression, whether or not followed by the same; (b) references to the singular shall include the plural and vice versa; (c) references to masculine, feminine, and neuter pronouns and expressions shall be interchangeable; (d) the words “herein” or “hereunder” relate to this Agreement; (e) the term “or” will be interpreted in the inclusive sense commonly associated with the term “and/or” unless preceded by the word “either” or other language indicating the subjects of the conjunction are, or are intended to be, mutually exclusive; (f) the word “will” shall be construed to have the same meaning and effect as the word “shall”; (g) all references to “dollars” or “$” herein shall mean U.S. Dollars; and (h) a capitalized term not defined herein but reflecting a different part of speech from that of a capitalized term which is defined herein shall be interpreted in a correlative manner.

In interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and provisions.

Section 12.12Counterparts. This Agreement may be executed in two (2) counterparts, each of which shall be deemed an original, and both of which together shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a fax machine or by .pdf, .tif, .gif, .jpeg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a claim or defense with respect to the formation of a contract, and each Party forever waives any such claim or defense, except to the extent that such claim or defense relates to lack of authenticity.

Section 12.13Equitable Relief. Notwithstanding anything to the contrary herein, the Parties shall be entitled to seek equitable relief, including injunction and specific performance, as a remedy for any breach of this Agreement. Such remedies shall not be deemed to be the exclusive remedies for a breach of this Agreement but shall be in addition to all other remedies available at law or equity.
