respect to any infringement of such patent by a Third Party and, in furtherance of such right, Wyeth hereby agrees that Cardiokine may include and join Wyeth as a party plaintiff in any such suit, without expense to Wyeth. 

In the event that Cardiokine determines to bring suit against an alleged Third Party infringer, the total cost of any such infringement action commenced
solely by Cardiokine shall be borne by Cardiokine, provided that Wyeth may elect to fund up to [####]of the out-of-pocket expenses and legal fees in return for up to
[####]of the recoveries as set forth below. Cardiokine shall keep any recovery or damages for past infringement derived therefrom, except that, Cardiokine shall share such balance in proportion to each Party’s share of such expenses and legal
fees, said balance to be calculated following, and subject to, reimbursement of expenses as described in Section 7.2.2.3 below. Ln the event such infringement adversely affects the scope or validity of the Licensed Patents, no settlement,
consent judgment or other voluntary disposition of any such suit may be entered into without the consent of Wyeth, which consent shall not be unreasonably withheld or delayed. Wyeth shall have [####]from the date of Cardiokine’s written notice
to Wyeth either to consent or to object in writing, stating in reasonable detail the reasons for withholding consent. No response within such period shall be deemed to constitute Wyeth’s consent. Notwithstanding the foregoing, Wyeth may elect
at its option to participate in the prosecution of any such infringement action through counsel of its own choice at its own expense. 

7.2.2.2 If within [####]after having been notified of any alleged infringement of the Licensed Patents by a Third Party, Cardiokine shall have
been unsuccessful in persuading the alleged infringer to cease and desist or shall not have brought and shall not be diligently prosecuting an infringement action, or if Cardiokine shall notify Wyeth at any time prior thereto of its intention not to
bring suit against any alleged infringer then, and in those events only, Wyeth shall have the right, but shall not be obligated, to prosecute at its own expense any infringement of the Licensed Patents covering the Licensed Products, and Wyeth may,
for such purposes, include and join Cardiokine as party plaintiff in any such suit, without expense to Cardiokine. In such event, the total cost of any such infringement action commenced solely by Wyeth shall be borne by Wyeth, provided that
Cardiokine may elect to fund up to [####]of the out-of-pocket expenses and legal fees in return for up to [####] of the recoveries as set forth below. Wyeth shall keep
any recovery or damages for past infringement derived therefrom, except that,

legal fees as described in Section 7.2.23 below. In the event such infringement adversely affects the scope or validity of the Licensed Patents, no settlement, consent judgment or other voluntary final disposition of the suit may be entered
into without the consent of Cardiokine, which consent shall not be unreasonably withheld or delayed. Cardiokine shall have [####]from the date of Wyeth’s written notice to Cardiokine either to consent or to object in writing, stating in
reasonable detail the reasons for withholding consent. No response within such period shall be deemed to constitute Cardiokine’s consent. Notwithstanding the foregoing, Cardiokine may elect at its option to participate in the prosecution of any
such infringement action through counsel of its own choice at its own expense. 
 7.2.2.3 In the event either Party shall undertake die
enforcement of the Licensed Patents covering the Licensed Products, any recovery of damages by such Party for such suit shall be applied first in satisfaction of any expenses and legal fees of such Party (and, if applicable, the expenses and legal
fees of the other Party that has elected to and has paid up to [####]of the out-of-pocket expenses and legal fees associated with said enforcement) relating to such
enforcement and the balance remaining from any such recovery distributed as set forth in Section 7.2.2.1 or Section 7.2.2.2, as the case may be. 

7.2.2.4 In any infringement suit which either Party may institute to enforce the Licensed Patents pursuant to this Agreement, or in a suit for
patent infringement which is brought by a Third Party against Wyeth or Cardiokine, which either Party or both Parties are required or elect to defend, the other Party hereto shall, at the request and the expense of the Party initiating or defending
such suit, cooperate in all reasonable respects and, to the extent reasonably possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens, and the like. 

7.2.2.5 Cardiokine shall have the sole right subject to the terms and conditions hereof to sublicense any alleged infringer for future use of
the Licensed Patents for Licensed Products. Any upfront fees paid to Cardiokine as part of a sublicense agreement made in settlement of the infringement action shall be applied first in satisfaction of any expenses and legal fees of Cardiokine
relating to such suit and the balance remaining from any such recovery distributed as set forth in Section 7.2.2.1 above. 
 7.3
Infringement Defense. Cardiokine shall have the right, but not the obligation, to defend and control any suit against any of Cardiokine, Cardiokine’s Affiliates or sublicensees, alleging infringement of any patent or other
intellectual property right of a Third Party arising out of the manufacture, use, sale offer to sell or importation of a Licensed Compound or Licensed Product by Cardiokine, Cardiokine’s Affiliates or sublicensees. Cardiokine shall be
responsible for the costs and expenses, including lawyer’s fees and costs, associated with any suit or action, Cardiokine and Wyeth will consult with one another and cooperate in the defense of any such action. If Cardiokine finds it necessary
or desirable to join Wyeth as a party to any such action, Wyeth will execute all papers and perform such acts as shall be reasonably required, at Cardiokine’s expense. In the event the patent claim of any Third Party is held in a final and
unappealable order of a court to be valid and infringed, or if Cardiokine enters into a settlement of such proceedings, Cardiokine shall pay the foil amount of any damages and/or settlement amounts due to such Third Party.

thereto) claiming that a Licensed Patent covering any Licensed Product is invalid or that infringement of such Licensed Patent will not arise from the development, manufacture, use or sale of any product by a Third Party. The provisions of
Section 7.2.2 shall thereafter apply as if such Third Party were an infringer or suspected infringer. 
 7.5 Patent Term
Restoration. Cardiokine and Wyeth shall cooperate in obtaining patent term restoration or any similar benefit for the Licensed Patents. Wyeth and Cardiokine shall discuss which countries in which such patent term restoration or similar
benefits are to be sought and Wyeth shall seek such restoration in any country selected by Cardiokine. Cardiokine shall, at Wyeth’s reasonable request and at Wyeth’s expense, take all actions and execute all documents as reasonably
necessary or appropriate to accomplish same. In the event that Wyeth elects not to seek restoration in a country selected by Cardiokine, Wyeth shall cooperate with Cardiokine in securing restoration in such country by taking all actions and
executing all documents as reasonably necessary or appropriate to accomplish same. In such event, Cardiokine shall apply the cost for seeking such restoration as an advance on royalties to be paid to Wyeth.

registration once obtained), one or more Trademarks for use in connection with Commercializing the Licensed Products; provided, that if Wyeth and Cardiokine enter into a Marketing Partnership pursuant to Section 6, Wyeth shall be

(collectively, a “Liability”) that the Wyeth Indemnified Party may incur or be required to pay resulting from or arising out of and one or more of the following: 

(i) any Third Party claims of any nature arising out of the Research, Development, Manufacture or Commercialization of Licensed Compound(s)
and Licensed Product(s) by or on behalf or under the authority of any Cardiokine Indemnified Party (as defined in Section 12.2) or any sublicensee or subcontractor of any Cardiokine Indemnified Party, including, without limitation, in

without limitation, in connection with the conduct of any clinical trials or obtaining or maintenance of Regulatory Approvals in the event Wyeth receives the license rights specified in Section 11.5 or otherwise; and (ii) the material
breach by Wyeth of any of its representation or warranties set forth in this Agreement.

other in the event it becomes aware of a claim for which indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be

a corporation organized and existing under the laws of the State of Delaware and having a principal place of business at Five Giralda Farms, Madison, New Jersey 07940, acting through its Wyeth Pharmaceuticals Division (“Wyeth”), and
Cardiokine, Inc., a corporation organized and existing under the laws of the State of Delaware and having a principal place of business at 3701 Market Street, 4th Floor, Philadelphia, PA 19104 (“Cardiokine”). Wyeth and Cardiokine may each
be referred to herein individually, as a “Party” and collectively, as the “Parties”. 
 WHEREAS, the Parties entered
into that certain License Agreement dated March 15,2004 (the “License Agreement”), and 
 WHEREAS, the
Parties now wish to amend the License Agreement, as set forth in this Amendment. 
 NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows: 
 1. Amendment. 

1.1 The Parties hereby agree to amend the License Agreement to add the following new Section 4.6: 

4.6. Transfer of IND to Cardiokine. Wyeth shall assign to Cardiokine [####] (hereinafter, the IND ), (b) provide Cardiokine with a complete
copy of the IND, and (c) submit a letter to the FDA stating that the IND has been assigned to Cardiokine. Cardiokine shall submit a letter to FDA, together with a revised first page of the IND (a completed Form 1571), accepting the ownership of
the IND and identifying the effective date of the transfer of the IND. The disclaimer of warranties in Section 9.1 of this Agreement shall apply to the IND and all studies, data and information in the IND. 

1.2 The Parties hereby agree to further amend the License Agreement to delete the current Section 6.1 of the License Agreement in its
entirety and replace it with the following new Section 6.1: 
 6.1 Right of First Negotiation. 

In the event Cardiokine at any time seeks or determines to enter into a marketing partnership,
co-promotion or other equivalent or similar arrangement (a “Marketing Partnership”) for a Licensed Product within the Territory, Cardiokine shall provide Wyeth with written notice thereof (the
“Initial Notice”) and comply with this Section 6.1 prior to negotiating with any Third Party for such Marketing Partnership. Cardiokine shall also provide ‘to Wyeth, together with such written notice, an electronic copy of the
NDA submitted to the FDA for such Licensed Product (if one 












 
has been submitted at the time of such Initial Notice) as well as the market studies and reports and other similar or related information and data in respect of such Licensed Product in
Cardiokine’s or its Affiliates’ possession or control in order for Wyeth to determine its interest in entering into a Marketing Partnership with Cardiokine. All such information provided to Wyeth hereunder shall be deemed to be
Confidential Information of Cardiokine. Wyeth shall have [####]from the date of its receipt of the Initial Notice to give Cardiokine written notice that it is exercising ‘ its right to negotiate with Cardiokine regarding a Marketing Partnership
(such notice being an “Exercise Notice”). If Wyeth gives Cardiokine an Exercise Notice within the foregoing [####]period, then during the period beginning on the date of the Exercise Notice and ending on the date that is [####]after the
date of the Exercise Notice, the Parties shall promptly and diligently negotiate, on an exclusive basis and in good faith, to enter into a Marketing Partnership for such Licensed Product on commercially reasonable terms If (i) Wyeth fails to
give an Exercise Notice within the foregoing [####]period or (ii) if the Parties are unable, within the foregoing [####], to enter into a term sheet or letter of intent setting forth the principal terms of the Marketing Partnership to be
entered into, or (iii) if the Parties are unable to enter into a definitive agreement setting forth all the terms and conditions of the Marketing Partnership within [####]after entering into said term sheet or letter of intent, then Cardiokine
shall be free to negotiate and enter into an agreement for a Marketing Partnership for such Licensed Product (the “Marketing Partnership Agreement”) with any Third Party; provided that the terms of the Marketing Partnership
Agreement with the Third Party, taken as a whole, may not be less favorable to Cardiokine than those last offered to Wyeth or proposed by Wyeth; and provided, further, that the Marketing Partnership Agreement must comply with the terms and
conditions of this Agreement. If the terms of the Marketing Partnership Agreement with the Third Party, taken as a whole, are less favorable to Cardiokine than those last offered to Wyeth or proposed by Wyeth, then Cardiokine may offer such terms
(the “Alternative Offer”) to Wyeth, and if Wyeth does not, within [####]of its receipt of the Alternative Offer, notify Cardiokine of its acceptance thereof and willingness to enter into further negotiations (the “Second Exercise
Notice”) to enter into a Marketing Partnership Agreement, then Cardiokine shall be free to enter into such Marketing Partnership Agreement with such Third Party. In the event that Wyeth gives Cardiokine the Second Exercise Notice, the parties
shall negotiate in good faith for a period not to exceed [####], unless otherwise mutually agreed, and if a definitive Marketing Partnership Agreement shall not be concluded, then Cardiokine shall be entitled to enter into such Agreement with the
Third Party. The provisions applicable to Cardiokine under this Article 6 shall also apply to any Affiliate of Cardiokine to which Cardiokine has granted or otherwise extended its rights hereunder.

Except as otherwise expressly modified by this Amendment, the License Agreement shall remain in full force and effect in accordance with its terms. 
 3.
Defined Terms. All terms used, but not defined, in this Amendment shall have the respective meanings as set forth in the License Agreement. 
 4.
Counterparts. This Amendment may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

IN WITNESS WHEREOF, duly authorized representatives of the Parties have duly executed this Amendment to be effective as of the Amendment Date.
