5

Priority Secured Party or Second Priority Secured Party to perfect its security interests in the Common Collateral or any avoidance, invalidation or subordination by any third party or court of competent jurisdiction of the security interests in the Common Collateral granted to the First Priority Secured Parties or the Second Priority Secured parties, the priority and rights as between the First Priority Secured Parties and the Second Priority Secured Parties with respect to the Common Collateral shall be as set forth herein.

2.2. Nature of First Priority Obligations. The Second Priority Representative on behalf of itself and the other Second Priority Secured Parties acknowledges that the terms of the First Priority Obligations may be modified, extended or amended from time to time, and that the aggregate amount of the First Priority Obligations may be increased, replaced or refinanced, in each event, without notice to or consent by the Second Priority Secured Parties and without affecting the provisions hereof. The lien priorities provided in Section 2.1 shall not be altered or otherwise affected by any such amendment, modification, supplement, extension, repayment, reborrowing, increase, replacement, renewal, restatement or refinancing of either the First Priority Obligations or the Second Priority Obligations, or any portion thereof.

2.3. Agreements Regarding Actions to Perfect Liens. (a) The Second Priority Representative on behalf of itself and the other Second Priority Secured Parties agrees that UCC-1 financing statements, patent, trademark or copyright filings or other filings or recordings filed or recorded by or on behalf of the Second Priority Representative, subsequent to the date hereof, shall be in form satisfactory to the First Priority Creditor.

(b) The Second Priority Representative agrees on behalf of itself and the other Second Priority Secured Parties that all mortgages, deeds of trust, deeds and similar instruments (collectively, “mortgages”) now or hereafter filed against Real Property that constitutes Common Collateral in favor of or for the benefit of the Second Priority Representative and the other Second Priority Secured Parties shall be in form satisfactory to the First Priority Creditor and shall contain the following notation: “The lien created by this mortgage on the property described herein is junior and subordinate to the lien on such property created by any mortgage, deed of trust or similar instrument now or hereafter granted to the First Priority Creditor, and its successors and assigns, in such property, in accordance with the provisions of the Intercreditor Agreement dated as of June 9, 2015 among QLT Inc., U.S. Bank National Association and InSite Vision Incorporated, as amended from time to time.”

(c) The First Priority Creditor hereby acknowledges that, to the extent that it holds, or a third party holds on its behalf, physical possession of or “control” (as defined in the Uniform Commercial Code) over Common Collateral pursuant to the First Priority Security Documents, such possession or control is also for the benefit of and on behalf of, and the First Priority Creditor or such third party holds such possession or control as bailee and agent for, the Second Priority Representative and the other Second Priority Secured Parties solely to the extent required to perfect their security interest in such Common Collateral (such bailment and agency for perfection being intended, among other things, to satisfy the requirements of Sections 8-301(a)(2) and 9-313(c) of the Uniform Commercial Code). Nothing in the preceding sentence shall be construed to impose any duty on the First Priority Creditor (or any third party acting on its behalf) with respect to such Common Collateral or provide the Second Priority Representative or any other Second Priority Secured Party with any rights with respect to such Common Collateral beyond those specified in this Agreement and the Second Priority Security Documents, provided that subsequent to the occurrence of the First Priority Obligations Payment Date, the First Priority Creditor shall (i) deliver to the Second Priority Representative, at the Company’s sole cost and expense, the Common Collateral in its possession or control together with any necessary endorsements to the extent required by the Second Priority Documents (and to the extent not so required, such delivery shall be made to the Company) or (ii) direct and deliver such Common Collateral as a court

6

of competent jurisdiction otherwise directs, and provided, further, that the provisions of this Agreement are intended solely to govern the respective Lien priorities as between the First Priority Secured Parties and the Second Priority Secured Parties and shall not impose on the First Priority Secured Parties any obligations in respect of the disposition of any Common Collateral (or any proceeds thereof) that would conflict with prior perfected Liens or any claims thereon in favor of any other Person that is not a Secured Party.

2.4. No New Liens. So long as the First Priority Obligations Payment Date has not occurred, the parties hereto agree that (a) neither the Company nor any of its subsidiaries shall have any right to create any Lien, on any assets of the Company or any such subsidiary securing any Second Priority Obligation and (b) if any Second Priority Secured Party shall acquire or hold any Lien on any assets of the Borrower securing any Second Priority Obligation which assets are not also subject to the first-priority Lien of the First Priority Creditor under the First Priority Documents, then the Second Priority Representative, upon demand by the First Priority Creditor, will without the need for any further consent of any other Second Priority Secured Party, notwithstanding anything to the contrary in any other Second Priority Document either (i) release such Lien or (ii) assign it to the First Priority Creditor as security for the First Priority Obligations (in which case the Second Priority Representative may retain a junior lien on such assets subject to the terms hereof). To the extent that the foregoing provisions are not complied with for any reason, without limiting any other rights and remedies available to the First Priority Secured Parties, the Second Priority Representative and the other Second Priority Secured Parties agree that any amounts received by or distributed to any of them pursuant to or as a result of Liens granted in contravention of this Section 2.4 shall be subject to Section 4.1.

(c) they will not contest, oppose, object to, interfere with, hinder or delay, in any manner, whether by judicial proceedings (including without limitation the filing of an Insolvency Proceeding) or otherwise, any foreclosure, sale, lease, exchange, transfer or other disposition of the Common Collateral by any First Priority Secured Party or any other Enforcement Action taken (or any forbearance from taking any Enforcement Action) by or on behalf of any First Priority Secured Party;

(h) they will not commence judicial or nonjudicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, attempt any action to take possession of any Common Collateral, exercise any right, remedy or power with respect to, or otherwise take any action to enforce their interest in or realize upon, the Common Collateral or pursuant to the Second Priority Security Documents;

The Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties, that none of them will seek relief from the automatic stay or from any other stay in any Insolvency Proceeding or take any action in derogation thereof, in each case in respect of any Common Collateral, without the prior written consent of the First Priority Creditor.

5.4. Adequate Protection. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that none of them shall object, contest, or support any other Person objecting to or contesting, (a) any request by the First Priority Creditor or the other First Priority Secured Parties for adequate protection of its interest in the Common Collateral or any adequate protection provided to the First Priority Creditor or the other First Priority Secured Parties, (b) any objection by the First Priority Creditor or any other First Priority Secured Parties to any motion, relief, action or proceeding based on a claim of a lack of adequate protection in the Common Collateral or (c) the payment of interest, fees, expenses or other amounts to the First Priority Creditor or any other First Priority Secured Party under Section 506(b) or 506(c) of the Bankruptcy Code or otherwise. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, further agrees that, prior to the First Priority Obligations Payment Date, none of them shall assert or enforce any claim under Section 506(b) or 506(c) of the Bankruptcy Code or otherwise that is senior to or on a parity with the First Priority Liens for costs or expenses of preserving or disposing of any Common Collateral. Notwithstanding anything to the contrary set forth in this Section and in Section 5.2(b), but subject to all other provisions of this Agreement (including, without limitation, Section 5.2(a) and Section 5.3), in any Insolvency Proceeding, (i) if the First Priority Secured Parties (or any subset thereof) are granted adequate protection consisting of additional collateral that constitutes Common Collateral (with replacement liens on such additional collateral) and superpriority claims in connection with any DIP Financing or use of cash collateral with respect to the Common Collateral, and the First Priority Secured Parties do not object to the adequate protection being provided to them, then in connection with any such DIP Financing or use

11

of cash collateral the Second Priority Representative, on behalf of itself and any of the Second Priority Secured Parties, may, as adequate protection of their interests in the Common Collateral, seek or accept adequate protection consisting solely of (x) a replacement Lien on the same additional collateral, subordinated to the Liens securing the First Priority Obligations and such DIP Financing on the same basis as the other Second Priority Liens on the Common Collateral are so subordinated to the First Priority Obligations under this Agreement, (y) superpriority claims junior in all respects to the superpriority claims granted to the First Priority Secured Parties and (z) subject to the right of the First Priority Secured Parties to object thereto, the payment of post-petition interest at the pre- default rate (provided, in the case of this clause (z), that the First Priority Secured Parties have been granted adequate protection in the form of post-petition interest at a rate no lower than the pre-default rate), provided, however, that the Second Priority Representative shall have irrevocably agreed, pursuant to Section 1129(a)(9) of the Bankruptcy Code, on behalf of itself and the Second Priority Secured Parties, in any stipulation and/or order granting such adequate protection, that such junior superpriority claims may be paid under any plan of reorganization in any combination of cash, debt, equity or other property having a value on the effective date of such plan equal to the allowed amount of such claims and (ii) in the event the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, seeks or accepts adequate protection in accordance with clause (i) above and such adequate protection is granted in the form of additional collateral, then the Second Priority Representative, on behalf of itself or any of the Second Priority Secured Parties, agrees that the First Priority Creditor shall also be granted a senior Lien on such additional collateral as security for the First Priority Obligations and any such DIP Financing and that any Lien on such additional collateral securing the Second Priority Obligations shall be subordinated to the Liens on such collateral securing the First Priority Obligations and any such DIP Financing (and all Obligations relating thereto) and any other Liens granted to the First Priority Secured Parties as adequate protection, with such subordination to be on the same terms that the other Liens securing the Second Priority Obligations are subordinated to such First Priority Obligations under this Agreement. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that except as expressly set forth in this Section none of them shall seek or accept adequate protection with respect to their interests in the Common Collateral without the prior written consent of the First Priority Creditor.

5.5. Avoidance Issues. If any First Priority Secured Party is required in any Insolvency Proceeding or otherwise to disgorge, turn over or otherwise pay to the estate of the Company, because such amount was avoided or ordered to be paid or disgorged for any reason, including without limitation because it was found to be a fraudulent or preferential transfer, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of set-off or otherwise, then the First Priority Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the First Priority Obligations Payment Date shall be deemed not to have occurred. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto. The Second Priority Secured Parties agree that none of them shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

5.6. Asset Dispositions in an Insolvency Proceeding. In an Insolvency Proceeding or otherwise, neither the Second Priority Representative nor any other Second Priority Secured Party shall oppose any sale or disposition of any assets of the Company that is supported by the First Priority Secured Parties, and the Second Priority Representative and each other Second Priority Secured Party will be deemed to have consented under Section 363 of the Bankruptcy Code (or otherwise) to any sale supported by the First Priority Secured Parties and to have released their Liens on such assets.

12

5.7. Separate Grants of Security and Separate Classification. Each Secured Party acknowledges and agrees that (a) the grants of Liens pursuant to the First Priority Security Documents and the Second Priority Security Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Common Collateral, the First Priority Obligations and the Second Priority Obligations are fundamentally different from each other and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the First Priority Secured Parties and Second Priority Secured Parties in respect of the Common Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then the Second Priority Secured Parties hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Company in respect of the Common Collateral, with the effect being that, to the extent that the aggregate value of the Common Collateral is sufficient (for this purpose ignoring all claims held by the Second Priority Secured Parties), the First Priority Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of Post-Petition Interest before any distribution is made in respect of the claims held by the Second Secured Priority Secured Parties. The Second Priority Secured Parties hereby acknowledge and agree to turn over to the First Priority Secured Parties amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of the preceding sentence, even if such turnover has the effect of reducing the claim or recovery of the Second Priority Secured Parties.

5.8. No Waivers of Rights of First Priority Secured Parties. Nothing contained herein shall prohibit or in any way limit the First Priority Creditor or any other First Priority Secured Party from objecting in any Insolvency Proceeding or otherwise to any action taken by any Second Priority Secured Party, including the seeking by any Second Priority Secured Party of adequate protection (except as provided in Section 5.4).

5.9. Plans of Reorganization. No Second Priority Secured Party shall propose, support or vote in favor of any plan of reorganization (and each shall be deemed to have voted to reject any plan of reorganization) unless such plan (a) pays off, in cash in full, all First Priority Obligations or (b) is accepted by the class of holders of First Priority Obligations voting thereon and is supported by the First Priority Creditor.

5.10. Other Matters. To the extent that the Second Priority Representative or any Second Priority Secured Party has or acquires rights under Section 363 or Section 364 of the Bankruptcy Code (or otherwise) with respect to any of the Common Collateral, the Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties not to assert any of such rights without the prior written consent of the First Priority Creditor; provided that if requested by the First Priority Creditor, the Second Priority Representative shall, at the sole cost and expenses of the Company, timely exercise such rights in the manner requested by the First Priority Creditor, including any rights to payments in respect of such rights.

5.11. Effectiveness in Insolvency Proceedings. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under section 510(a) of the Bankruptcy Code, shall be effective before, during and after the commencement of an Insolvency Proceeding.

13

SECTION 6. Security Documents.

(a) The Company and the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the Second Priority Documents in violation of this Agreement.

(b) The Company and the First Priority Creditor, on behalf of itself and the First Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the First Priority Documents in violation of this Agreement.

(c) In the event the First Priority Creditor enters into any amendment, waiver or consent in respect of any of the First Priority Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any First Priority Security Document or changing in any manner the rights of any parties thereunder (other than with respect to amendments, modifications or waivers that secure additional extensions of credit and add additional secured creditors or add additional guarantees or collateral), then such amendment, waiver or consent shall apply to any comparable provision of the Comparable Second Priority Security Document (with all such amendments, waivers and modifications subject to the terms hereof) and the Company and the Second Priority Secured Parties (and the required Second Priority Secured Parties shall instruct the Second Priority Representative in writing to execute the same) will work in good faith to promptly negotiate and execute any necessary amendments to such Comparable Second Priority Security Documents to give effect to this Section 6(c); provided, that (i) no such amendment, waiver or consent shall have the effect of removing assets subject to the Lien of any Second Priority Security Document, except to the extent that a release of such Lien is permitted by Section 4.2, (ii) any such amendment, waiver or consent that materially and adversely affects the rights of the Second Priority Secured Parties (other than the Second Priority Representative) and does not affect the First Priority Secured Parties in a like or similar manner shall not apply to the Second Priority Security Documents without the consent of the Second Priority Representative (to be given or withheld in accordance with the Second Priority Agreement), and (iii) notice of such amendment, waiver or consent shall be given to the Second Priority Representative no later than 30 days after its effectiveness; provided that the failure to give such notice shall not affect the effectiveness and validity thereof. The Second Priority Documents may not be amended in a manner that would increase (i) the principal amount thereunder or (ii) the interest rate thereon, in each case, without the prior written consent of the First Priority Creditor.

(d) The First Priority Obligations and the Second Priority Obligations may be refinanced or replaced, in whole or in part, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit the refinancing transaction under any First Priority Agreement or any Second Priority Agreement) of any First Priority Secured Party or any Second Priority Secured Party, all without affecting the Lien priorities provided for herein or the other provisions hereof; provided, however, that the holders of any such refinancing or replacement Indebtedness (or an authorized agent or trustee on their behalf) bind themselves in writing to the terms of this Agreement pursuant to such documents or agreements (including amendments or supplements to this Agreement) as the First Priority Creditor or the Second Priority Representative, as the case may be, shall reasonably request and in form and substance reasonably acceptable to the First Priority Creditor or the Second Priority Representative, as the case may be; provided that such documents or agreements shall comply with Section 6(a) and Section 6(b).

(e) If at any time in connection with or after the discharge of all First Priority Obligations, the Company enters into any replacement First Priority Agreement secured by all or a portion of the First Priority Collateral on a first-priority basis, then such prior discharge of First Priority Obligations shall automatically be deemed not to have occurred for the purposes of this Agreement, and

14

the obligations under such replacement First Priority Agreement shall automatically be treated as First Priority Obligations for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of the First Priority Collateral (or such portion thereof) set forth therein; provided that, the First Priority Secured Parties, the Second Priority Secured Parties (and the required Second Priority Secured Parties shall instruct the Second Priority Representative to execute the same) and the Company will work in good faith to promptly negotiate and execute an amendment to this Agreement giving effect to this Section 6(e).

(f) In connection with any refinancing or replacement contemplated by Section 6(d) or 6(e), this Agreement may be amended at the request and sole expense of the Company, and without the consent of the First Priority Creditor, the First Priority Secured Parties, or the Second Priority Representative or the Second Priority Secured Parties (a) to add parties (or any authorized agent or trustee therefor) providing any such refinancing or replacement indebtedness, (b) to establish that Liens on any First Priority Collateral securing such refinancing or replacement indebtedness shall have the same priority (or junior priority) as the Liens on any First Priority Collateral securing the Indebtedness being refinanced or replaced and (c) to establish that Liens on any Second Priority Collateral securing such refinancing or replacement indebtedness shall have the same priority as the Liens on any Second Priority Collateral securing the indebtedness being refinanced or replaced, all on the terms provided for immediately prior to such refinancing or replacement.

SECTION 7. Reliance; Waivers; etc.

7.1. Reliance. The First Priority Documents are deemed to have been executed and delivered, and all extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, expressly waives all notice of the acceptance of and reliance on this Agreement by the First Priority Secured Parties. The Second Priority Documents are deemed to have been executed and delivered and all extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The First Priority Creditor expressly waives all notices of the acceptance of and reliance by the Second Priority Representative and the Second Priority Secured Parties.

7.2. No Warranties or Liability. The Second Priority Representative and the First Priority Creditor acknowledge and agree that neither has made any representation or warranty with respect to the execution, validity, legality, completeness, collectability or enforceability of any other First Priority Document or any Second Priority Document. Except as otherwise provided in this Agreement, the Second Priority Representative and the First Priority Creditor will be entitled to manage and supervise their respective extensions of credit to the Company in accordance with law, the relevant First Priority Documents and Second Priority Documents and their usual practices, modified from time to time as they deem appropriate.

7.3. No Waivers. No right or benefit of any party hereunder shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of such party or any other party hereto or by any noncompliance by the Company with the terms and conditions of any of the First Priority Documents or the Second Priority Documents.

15

All rights and interests of the Second Priority Secured Parties hereunder, and all agreements and obligations of the First Priority Secured Parties (and, to the extent applicable, the Company) hereunder, shall remain in full force and effect irrespective of:

SECTION 9. Miscellaneous.

9.1. Conflicts. In the event of any conflict between the provisions of this Agreement and the provisions of any First Priority Document or any Second Priority Document, the provisions of this Agreement shall govern. Notwithstanding the foregoing, the parties hereto acknowledge that the terms of this Agreement are not intended to and shall not, as between the Company and the Secured Parties, negate, impair, waive or cancel any rights granted to, or carry liability or obligation of, the Company in the First Priority Documents and the Second Priority Documents or impose any additional obligations on the Company (other than as expressly set forth herein).

16

9.2. Continuing Nature of Provisions. This Agreement shall continue to be effective, and shall not be revocable by any party hereto, until the First Priority Obligation Payment Date shall have occurred. This is a continuing agreement and the First Priority Secured Parties and the Second Priority Secured Parties may continue, at any time and without notice to the other parties hereto, to extend credit and other financial accommodations, lend monies and provide indebtedness to, or for the benefit of, the Company on the faith hereof.

9.3. Amendments; Waivers. (a) No amendment or modification of any of the provisions of this Agreement shall be effective unless the same shall be in writing and signed by the First Priority Creditor (in accordance with the First Priority Agreement) and the Second Priority Representative (in accordance with the Second Priority Agreement), and, in the case of amendments or modifications of Sections 3.5, 3.6, 5.2, 5.4, 6(c), 6(d), 6(e), 6(f), 9.3, 9.5 or 9.6, the Company, and each waiver, if any, shall be a waiver only with respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations of the other parties to such party in any other respect or at any other time. Anything herein to the contrary notwithstanding, no consent of the Company shall be required for amendments, modifications or waivers of any other provisions of this Agreement other than those that (i) directly affect any obligation or right of the Company hereunder or under the First Priority Documents or the Second Priority Documents or that would impose any additional obligations on the Company or (ii) change the rights of the Company to refinance the First Priority Obligations or the Second Priority Obligations.

9.4. Information Concerning Financial Condition of the Company. Neither the Second Priority Representative nor the First Priority Creditor hereby assumes responsibility for keeping each other informed of the financial condition of the Company and all other circumstances bearing upon the risk of nonpayment of the First Priority Obligations or the Second Priority Obligations.

9.5. Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.

9.6. Submission to Jurisdiction. (a) Each First Priority Secured Party, each Second Priority Secured Party and the Company hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the courts of the State of New York and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each such party hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each such party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the any First Priority Secured Party or Second Priority Secured Party may otherwise have to bring any action or proceeding against the Company or its properties in the courts of any jurisdiction.

17

(b) Each First Priority Secured Party, each Second Priority Secured Party and the Company hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so (i) any objection it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (a) of this Section and (ii) the defense of an inconvenient forum to the maintenance of such action or proceeding.

All such notices and other communications (i) sent by hand or overnight courier service, or mailed by certified or registered mail, shall be deemed to have been given when received or (ii) sent by facsimile shall be deemed to have been given when sent, provided that if not given during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next business day for the recipient.

9.8. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of each of the parties hereto and each of the First Priority Secured Parties and Second Priority Secured Parties and their respective successors and permitted assigns, and nothing herein is intended, or shall be construed to give, any other Person any right, remedy or claim under, to or in respect of this Agreement or any Common Collateral.

9.9. Headings. Section headings used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

9.10. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

9.11. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by email or telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. This Agreement shall become effective when it shall have been executed by each party hereto.

9.12. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN.

18

9.13. Termination; QLT Default. Notwithstanding anything to the contrary contained in this Agreement:

(a) upon the occurrence of the Closing Date (as defined in the Merger Agreement, the “Merger Agreement Closing Date”)), (i) all Liens in favor of any Second Priority Secured Party securing the Second Priority Obligations shall be deemed to rank senior in all respects to the Liens in favor of the First Priority Secured Parties securing the First Priority Secured Obligations, (ii) the First Priority Creditor shall promptly deliver to the Second Priority Representative or its designees any and all possessory Common Collateral that it is holding pursuant to the terms of the First Priority Documents, and (iii) in furtherance of the foregoing, the First Priority Creditor and the Majority Holders (as defined in the Existing Second Priority Agreement) (who shall instruct the Second Priority Representative to execute the same) will work in good faith to promptly negotiate and execute an amendment to this Agreement providing that QLT Inc., as the First Priority Creditor under this Agreement, shall become the second priority creditor and U.S. Bank National Association, as collateral agent, and as the Second Priority Representative under this Agreement, shall become the first priority creditor, all on terms substantially equivalent to those set forth in this Agreement governing the relative priorities and rights of the First Priority Creditor and Second Priority Creditors (the “Post Merger Amended Intercreditor Agreement”), upon and after which the Post Merger Amended Intercreditor Agreement shall be deemed the “Intercreditor Agreement” as defined in the Existing First Priority Agreement; and

(b) upon the occurrence, and during the continuation of, a QLT Default (i) all Liens in favor of any Second Priority Secured Party securing the Second Priority Obligations shall be deemed to rank pari passu in all respects with the Liens in favor of the First Priority Secured Parties securing the First Priority Secured Obligations and (ii) in furtherance of the foregoing, the First Priority Creditor and the Majority Holders (as defined in the Existing Second Priority Agreement) (who shall instruct the Second Priority Representative to execute the same) will work in good faith to promptly negotiate and execute an amendment to this Agreement to give effect to such pari passu ranking.
