Any such reference for any other person shall refer to generally accepted accounting principles as approved by the appropriate accounting body having jurisdiction over the financial statements prepared by such person.

Best of Knowledge. "To the best of the knowledge" or "to the knowledge", unless otherwise qualified hereunder means a statement of the declaring Party’s knowledge of the actual facts or circumstances to which such phrase relates without having made any inquiries or investigations in connection with such facts and circumstances.

License. Subject to the terms and conditions of this Agreement, Institutions grant to TTI an exclusive, royalty-bearing license, with the further right to grant sublicenses subject to Section 2.5, in any and all of their rights in and to the Licensed Technology to commercialize said Licensed Technology for the Field in the Territory, which includes the right to research, develop, manufacture, have manufactured, use, have used, sell or have sold, offer for sale, import and export Product(s) and Service(s) (the “License”).

Restriction. The License granted to TTI under Section 2.1 is subject to Institutions’ retention of their rights to use the Licensed Technology without charge for research, scholarly publication, educational or other non-commercial use, with a further retention of its right to grant licenses to third parties for similar such purposes, subject to the Confidential Information and Publication provisions of this Agreement.

Improvements by Institutions. TTI is granted a right of first refusal to negotiate an exclusive, royalty bearing license to any Improvements by Institutions. TTI will have thirty (30) days after receiving written notice of an Improvement by Institutions to indicate its intent in writing (to UHN on behalf of Institutions) to license said Improvement by Institutions ("Notice of Intent"). If UHN (on behalf of Institutions) does not receive a Notice of Intent within this thirty (30) day period, TTI’s right of first refusal in respect of the improvements referred to in the written notice of an improvement will lapse and Institutions will be free to dispose of such Improvement by Institutions as they see fit. Upon UHN’s receipt of a Notice of Intent, the Parties shall engage in good faith negotiations in respect of any such prospective license. Any such license shall be on terms and conditions that are consistent with other such licenses within the industry and satisfactory to Institutions. If a license agreement has not been signed within one hundred-and- twenty (120) days of said receipt of a Notice of Intent (or such other period of time as the Parties may agree to), Institutions will be free to exploit and/or dispose of the Improvement by Institutions as they see fit.

Sublicenses. TTI shall have a right to grant sublicenses to the Licensed Technology to a third party sublicensee (“Sublicensee”) with the prior consent of UHN and HSC, which consent shall not be unreasonably withheld and can be withheld only on the basis of (a) reasonable concerns expressed by the Institutions having regard to the identity of the Sublicensee, or (b) for ethical reasons having regard to the identity or operations of the Sublicensee. UHN and HSC shall provide consent within thirty (30) days of a request from TTI.

Payment of Funds. UHN shall be responsible for the receipt of payments on behalf of Institutions, and for the transferring to HSC of HSC’s share of revenues received under this Agreement. Payment to be made by TTI to Institutions hereunder shall be made by cheque payable to the order of “University Health Network” and sent to the following address:

Up-Front License Fee. The Institutions acknowledge that TTI has previously paid to Institutions an up-front, non- refundable and non-creditable license fee of $150,000 on execution of the First License Agreement.

R&D Maintenance Fee. TTI shall pay to Institutions a yearly non-refundable and non- creditable maintenance fee of $25,000 (the “R&D Maintenance Fee”). The R&D Maintenance Fee shall be due on the yearly anniversary of the Effective Date; yearly payments of the R&D Maintenance Fee shall end on the sale of a first Product for which royalties are owed to Institutions further to this Agreement.

Milestone Payments. In partial consideration of the License, TTI shall pay to Institutions the following milestone payments:

Patent Issuance Milestones:

$25,000 for a first patent issued in the U.S.,

$200,000 for the dosing of a first patient in a first FDA-approved (or alternatively, foreign equivalent) Phase- II clinical trial, and

$300,000 for the dosing of a first patient in a first FDA-approved (or alternatively, foreign equivalent) Phase- III clinical trial;

Regulatory Milestones:

$1,000,000 for the submission of a first BLA in the U.S.,

$1,000,000 for the submission of a first BLA in the European Union,

$500,000 for the submission of a first BLA in Asia (which includes without limitation, China, Japan and India),

$1,000,000 for receipt of a first regulatory approval in the U.S.,

$1,000,000 for receipt of a first regulatory approval in the European Union,

$500,000 for receipt of a first regulatory approval in Asia (which includes without limitation, China, Japan and India), and

fifty percent (50%) of the milestone payments noted in Subsections 3.4(c)(i) - (vi) for each subsequent additional BLA submission(s) and regulatory approval(s) in any particular jurisdiction.

Basic Royalty. TTI shall pay a royalty of

three percent (3%) of Net Revenues from Product covered by a Valid Claim; or

one percent (1%) of Net Revenues from Product that is not covered by a Valid Claim but uses Licensed Technology.

Royalty payments shall be made on Net Revenues received by TTI in each Quarter Yearly Period (“Basic Royalty”). Payment(s) shall be made within thirty (30) days of the end of each Quarter Yearly Period (and, for greater certainty, shall only be payable in respect of Net Sales by Sublicensees to the extent that the Sublicensees have remitted royalty payments in respect of such Net Sales to TTI or its Affiliates). In the event that TTI obtains a license from one or more third parties in respect of intellectual property rights of said third party which are reasonably useful for the development or manufacturing of a Product or Service or further essentially required for the sale of a Product or Services, Basic Royalty payments under this Section 3.3 shall be reduced by the amount payable by TTI to such third parties that is allocable to the sale of Product or Service (whether such payments take the form of royalties, milestone payments or otherwise); provided however, that in no event will a deduction, or deductions, under this Section 3.5 reduce any royalty payment to Institutions in respect of Net Revenues of Product or Service by more than fifty percent (50%). If, but for the proviso in the preceding sentence, the deduction under this Section 3.5 would have reduced a royalty payment to Institutions by more than fifty percent (50%), the amount of such deduction that exceeds fifty percent (50%) shall not be carried over to subsequent or future royalty payments owed by TTI to Institutions.

Date of Sale. Products and Services will be deemed sold and revenue received when Product is shipped, or Service provided by, the TTI, the TTI Affiliate or Sublicensee as appropriate.

Sublicensing Royalty. This Section 3.7 outlines obligations taking effect as of the Execution Date and replaces previous obligations as outlined in the Existing Agreement in respect of that section. Upon the Execution Date, or as soon thereafter as practicable, but no later than thirty (30) days after the Execution Date, TTI shall issue: (a) to UHN a one-time allocation of TTI common shares, in an amount equal to $2,000,000.00 and (b) to HSC, a one-time allocation of TTI common shares in an amount equal to $1,000,000.00 (collectively the “TTI Equity”). The price per share of TTI Equity shall be determined as a volume weighted average price of the TTI common shares on the Toronto Stock Exchange over the fourteen (14) day period preceding the date of issuance. For clarity, this one time allocation of TTI Equity to each of the Institutions shall be non-refundable and non-creditable against future royalties (including the Basic Royalty) or milestones payable under this Agreement.

(intentionally left blank)

Interest. All monies payable to Institutions by TTI hereunder and not paid when due bear interest at the prime rate of interest quoted by the Bank of Canada, plus 5% (five percent) per annum until the date paid to Institutions. Institutions will be entitled to that interest in addition to any other rights or remedies available to it in respect of TTI’s payment default.

Withholdings. In the event that TTI is required by any law to withhold and/or make payments to tax authorities in respect of any payments payable by TTI to Institutions under this Agreement, the liability of TTI under this Agreement shall be to that extent satisfied, and such amounts shall be deemed to have been paid to Institutions on their due dates, provided that TTI shall furnish to Institutions acceptable evidence of such payments.

Royalty Report. TTI shall prepare a report (the "Royalty Report"), setting out the Gross Revenue, the number of Products manufactured and Services rendered, an itemized statement of all costs and disbursements and the Net Revenues, if any, for the relevant period. For so long as the Gross Revenue is less than $10,000 in any consecutive 12 month period, TTI shall prepare one Royalty Report for every 12 month period. If no payments are due for any reporting period, then the Royalty Report shall so state. Once the Gross Revenue is at least $10,000 in any consecutive 12-month period, TTI shall prepare a Royalty Report for each Quarter Yearly Period. Royalty Reports shall be due within thirty (30) days of the end of the relevant reporting period (provided that such Royalty Report shall only include information in respect of Gross Revenue generated by Sublicensees upon receipt of such information by TTI from the Sublicensees, which shall not be later than 75 days following the end of a particular quarterly period).

Complete Records. TTI and its Affiliates shall keep true and accurate records and books of account containing all data reasonably required for the computing and verification of all payments owed by TTI to Institutions, including records for Gross Revenue, the number of Products manufactured and Services rendered, costs/disbursements, and Net Revenues in accordance with applicable generally accepted accounting principles. Such records shall be maintained by TTI and its Affiliates for at least six (6) years from the date of the payment to which such records are relevant. In addition, TTI shall contractually require all Sublicensees to provide TTI with audit rights to permit TTI to verify amounts owing to TTI and its Affiliates, which rights shall be on terms and conditions, and based upon such scope of access, as TTI shall determine in its sole and absolute discretion.

Inspection of Records. The records of TTI and its Affiliates specified in this Agreement shall be available for inspection by Institutions or their duly appointed auditor, upon reasonable notice and during normal business hours at the principal place of business of TTI or its Affiliates, as applicable, for the sole purpose of verifying payments owed under this Agreement. The costs of any such inspection shall be borne by Institutions unless the report of an auditor shows that the Royalty Report(s) in respect of the period under review were understated by more than five percent (5%) in the aggregate, in which case the costs of the examination shall be paid by TTI.

Discrepancy in Records. In the event that the records inspection conducted under Section 3.13 reveals any underpayment of royalties due to Institutions, TTI will promptly pay Institutions the full amount of that underpayment together with interest thereon at the rate of interest referred to in Section 3.9 herein.

If after two (2) years of been notified of any material alleged infringement, TTI and/or Sublicensee(s) are unsuccessful in persuading the alleged infringer to desist or have not brought and have not diligently prosecuted an infringement action, then HSC and/or UHN shall have the right, but not the obligation, under their own control and at their own expense to prosecute such infringement of the Intellectual Property Rights in the Licensed Technology. Any monies awarded to the Parties as a result of any action or settlement shall first go to reimburse the prosecuting Parties for reasonable costs incurred in the action. The party bringing the action shall be entitled to any amount recovered as a result of such action.

No Actions. TTI agrees to not knowingly take any action which would jeopardize the obtaining or maintaining of Institutions’ Intellectual Property Rights in the Licensed Technology.

No Challenges. Except in those jurisdictions where such covenant is otherwise prohibited under applicable law, TTI agrees and shall cause its Affiliates to agree (and shall use reasonable commercial efforts to get its Sublicensee(s) to agree) that such persons shall not challenge the validity of any of Institutions’ Intellectual Property Rights in the Licensed Technology or otherwise under this Agreement.

A Receiving Party will neither use nor disclose to any other party any of the Confidential Information of the other Parties except as expressly permitted hereunder. For greater certainty, any information which the Institutions provide to TTI with respect to the Licensed Technology or in connection with the Research Programs may be used by TTI and its Affiliates and Sublicensees in furtherance of the commercialization of products and services.

Publications. At the request of UHN, HSC or TTI (as appropriate), TTI, HSC or UHN (as appropriate) shall acknowledge the contribution and ownership of the other Parties to the Licensed Technology, Improvements by Institutions or Improvements by TTI, as the case may be.
