13.5.5

Upon the expiration or termination of this Agreement for any reason, the parties’ rights and obligations under the following provisions shall survive: Clauses 11, 15 and 18; provided that the indemnification provision of Clause 15 shall survive only with respect to claims that are made prior to the expiry of a period of three (3) years after expiration or termination of this Agreement.

14.

RIGHT OF FIRST NEGOTIATION

14.1

The Parties acknowledge their mutual desire to explore a broader collaboration whereby Glycyx would develop and market CKD GI Products in the Glycyx Territory. Therefore, in addition to the exclusive rights granted to CKD in respect of the Product under Clause 2 CKD hereby grants to Glycyx a right of first negotiation with respect to rights to develop and exploit CKD GI Products in the Glycyx Territory.

14.2

During the period of [*] years from the date hereof CKD shall provide written notification to Glycyx of any opportunity in respect of a CKD GI Product (such notice, a “Product Notice”), which Product Notice shall be served promptly on any CKD GI Product being available for licensing outside the Territory. Such Product Notice shall contain a description in reasonable detail of the CKD GI Product(s) and such other information as may reasonably be required to enable Glycyx to assess the CKD GI Product opportunity. Upon request by Glycyx within [*] days after receipt of such Product Notice (the date of such receipt the “Notice Date” and such period the “Notice Period”), the Parties shall negotiate in good faith towards an agreement granting to Glycyx exclusive rights in respect of the CKD GI Product in the Glycyx Territory. If Glycyx chooses not to request such negotiations, it shall so notify CKD promptly before the expiry of the Notice Period and if Glycyx makes no communication within the Notice Period, it shall be deemed to have not effected a request. If notwithstanding good faith negotiations the Parties do not enter into a definitive agreement within [*] days of the Notice Date (the “Negotiation Period”), CKD may proceed to grant rights or licenses to Third Parties with respect to all or a part of the CKD GI Product(s) opportunity offered to Glycyx provided that CKD shall not enter into a transaction in respect of the CKD GI Product(s) opportunity in the Glycyx Territory proposed by CKD to Glycyx with a Third Party on terms which, assessed as a whole, are materially less favourable to CKD than those proposed by Glycyx in the course of the good faith negotiations during the Negotiation Period.

14.3	The only obligations of CKD and Glycyx under this Clause 14 are as expressly stated therein, and there are no further implied obligations relating to the matters contemplated therein.

[*]	Confidential treatment requested; certain information omitted and filed separately with the SEC.

15.

INDEMNITY

15.1

CKD. Subject to Glycyx’s compliance with its obligations set forth in Clause 15.3 below, CKD agrees to indemnify and hold Glycyx, its Affiliates and their employees and agents harmless from and against any losses, claims, damages, liabilities or actions (including reasonable attorneys’ fees and court and other expenses of litigation) (collectively, the “Liabilities”) suffered or incurred in connection with Third Party claims for personal injuries or any Product recall to the extent caused by the manufacture, use, sale or marketing of Product by CKD or its Sublicensees in the Territory Provided that CKD shall have no liability under this clause 15.1 if such Liability arises by reason of (or to the extent that such Liabilities arise by reason of;

15.1.1

any defect in any Balsalazide or Product supplied to CKD by Glycyx; or

15.1.2

the failure by Glycyx promptly to notify CKD of any Product recall effected in any other territory in which the Product may be sold or supplied; or

15.1.3

the failure by Glycyx promptly to notify CKD of any material adverse event of which Glycyx is aware in any territory which may reasonably be anticipated to require a Product recall in the Territory; or

15.1.4

the negligence, recklessness or intentional misconduct of Glycyx.

15.2

Glycyx. Subject to CKD’s compliance with its obligations set forth in Clause 15.3, Glycyx agrees to indemnify and hold CKD, its Affiliates, and Sublicensees and their employees and agents harmless from and against any Liabilities suffered or incurred in connection with third party claims for personal injuries or any Product recall to the extent caused by:

15.2.1

any defect in any Balsalazide or Product supplied to CKD by Glycyx; or

15.2.2

the failure by Glycyx promptly to notify CKD of any Product recall effected in any other territory in which the Product may be sold or supplied; or

15.2.3

15.2.4

the negligence, recklessness or intentional misconduct of Glycyx.

Notwithstanding the foregoing, Glycyx shall not be obligated to indemnify CKD or its Affiliates, Sublicensees and their employees and agents with respect to Liabilities incurred or to the extent incurred by reason of the negligence, recklessness or intentional misconduct of CKD or its Affiliates, Sublicensees and their employees and agents.

15.3

Procedure. A party (the “Indemnitee”) that intends to claim indemnification under this Clause 15 shall promptly notify the other party (the “Indemnitor”) in writing of any Liabilities in respect of which the Indemnitee or any of its Affiliates, employees or agents intend to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires to assume the defence thereof with counsel

mutually satisfactory to the parties; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if 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 party represented by such counsel in such proceeding. The indemnity agreement in this Clause 15 shall not apply to amounts paid in settlement of any Liabilities if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Clause 15, but the omission so to deliver written notice to the Indemnitor shall not relieve it of any liability that it may have to any Indemnitee otherwise than under this Clause 15. The Indemnitee under this Clause 15, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification.

16.

FORCE MAJEURE

Neither party shall be held liable or responsible to the other party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected party or from fire, floods, embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labour disturbances, acts of God or acts, omissions or delays in acting by any governmental authority.

17.

ASSIGNMENT

This Agreement may not be assigned or otherwise transferred, nor, except as expressly provided hereunder, may any right or obligations hereunder be assigned or transferred, by either party without the written consent of the other party; provided, however that either CKD or Glycyx may, without such consent, assign this Agreement and its rights and obligations hereunder to any Affiliate of such party in connection with the transfer of all or substantially all of its business relating to the Product to such Affiliate. Any purported assignment in violation of the preceding sentence shall be void. Any permitted assignee shall assume all obligations of its assignor under this Agreement. No assignment shall relieve either party of responsibility for the performance of any accrued obligation which such party then has hereunder.

18.
