All net selling prices of the elements of such Combination Product shall be calculated as the average net selling price of the said elements during the applicable accounting period for which the Net Sales are being calculated. In the event that, in any country, no separate sale of either such above-designated Licensed Product (containing only such Licensed Product and no other active ingredients) or any one or more of the active ingredients included in such Combination Product are made during the accounting period in which the sale was made or if the net selling price for an active ingredient cannot be determined for an accounting period, Net Sales for purposes of determining payments under this Agreement shall be calculated by multiplying the sales price of the Combination Product by a mutually agreed percentage based on the relative contribution of the Licensed Product and the other additional active ingredients.

Notwithstanding anything to the contrary, in the case of discounts on “bundles” of separate products or services which include Licensed Products (such “bundles” including but not limited to (w) situations where the Licensed Product is sold at a discount to induce the sale of other related or unrelated products, (x) contingent arrangements involving drugs that share the same NDC (whether the same or different package sizes), drugs with different NDCs, (y) circumstances in which a discount is conditioned on the achievement of some other performance requirement for the Licensed Product (e.g. achievement of market share or placement on a formulary tier), or (z) otherwise where the resulting price concessions or discounts are greater than those which would have been available had the bundled products been purchased separately or outside the bundled arrangement), TGTX may calculate Net Sales and royalties due hereunder by applying a discount to the price of a Licensed Product equal to the average percentage discount of all products of TGTX, its Affiliate(s), or Sublicensee(s) in a particular “bundle”, calculated as follows:

Average percentage

discount on a = [1 - (X/Y)] x 100

particular “bundle”

where X equals the total discounted price of a particular “bundle” of products, and Y equals the sum of the undiscounted bona fide list prices of each unit of every product in such “bundle”. If a Licensed Product in a “bundle” is not sold separately, and no bona fide list price exists for such Licensed Product, TGTX and Checkpoint shall, for purposes of calculating Net Sales and royalties due hereunder, negotiate in good faith a reasonable imputed list price for such Licensed Product and Net Sales with respect thereto shall be based on such imputed list price..

Undefined terms in the definition of Net Sales shall be construed in accordance with GAAP but only to the extent consistent with the express terms of the definition of Net Sales.

1.56 “Paragraph IV Certification” means a certification pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984 (Public Law 98-417), as amended, which shall include but not be limited to any such certification pursuant to 21 U.S.C. §355(b)(2)(A)(iv) or 21 U.S.C. §355(j)(2)(A)(vii)(IV), or any reasonably similar or equivalent certification or notice in the United States or any jurisdiction outside the United States, included in (or made with respect to or in connection with) a Regulatory Filing concerning a Licensed Product and challenging the validity, infringement, or enforceability of any Licensor Patent.

LICENSES AND OTHER RIGHTS

2.1 Grant of License to TGTX. Checkpoint, on behalf of itself and its Affiliates, hereby grants to TGTX and its Affiliates, and TGTX and its Affiliates hereby accept, an exclusive (even as to Checkpoint), royalty-bearing right and license (with the right to grant sublicenses in accordance with the provisions of Section 2.2) under the Licensor Technology to research, Develop, have Developed, Manufacture, have Manufactured, use, import, Commercialize and have Commercialized the Compound and Licensed Products in and for the Field and Territory.

All such transfers will be done in a reasonably secure manner using either encrypted media or encrypted transfer technology, or, if paper utilizing secure courier or tracked delivery processes. If, during the term of this Agreement Checkpoint possesses Licensor Know-How not previously provided to TGTX, it shall, within thirty (30) days after it comes into possession of such Licensor Know-How, provide copies of such Know-How to TGTX.

2.5 Non-Compete. On a country-by-country basis during the Royalty Term for each country (and with respect to an Abandoned Terminated Country, the Royalty Term for the United States), TGTX, its Affiliates and its Sublicensees shall not directly or indirectly engage in the research, development, Manufacture or commercialization of a Competing Product in such country. On a country-by-country basis during the Royalty Term for each country, Checkpoint, its Affiliates shall not directly or indirectly engage in the research, development, Manufacture or commercialization of a Competing Product in such country.

Within twenty (20) days of the end of each Calendar Year, TGTX shall prepare and provide to Checkpoint an updated Development Plan detailing any amendments, modifications and/or updates to any existing Development Plan along with a Development Report. For the avoidance of doubt, Development Plans are nonbinding and TGTX shall not be in breach of this Agreement if it does not Develop the Compound or Licensed Products in accordance with any Development Plan. Upon Regulatory Approval of a Licensed Product for a particular Major Country, TGTX’s obligations under this Section 3.2 shall terminate for that country.

3.3 Authority. As between TGTX and Checkpoint, TGTX shall have the exclusive right, and sole decision-making authority, to Develop, manufacture and Commercialize any Licensed Products in and for the Field (either itself or through its Affiliates, agents, subcontractors and/or Sublicensees).

3.6 Manufacturing. During the Term, TGTX and its Sublicensees shall have the sole obligation and responsibility, and at their sole cost and expense, for all aspects of Manufacturing, including without limitation, testing packaging and labeling the Licensed Products in and for the Field, and any costs associated with storage, release and Third Party logistics. TGTX and Sublicensees may engage contract Manufacturers to Manufacture (including labeling, packaging and testing) the Product. As a part of such responsibilities, TGTX covenants and agrees to use Commercially Reasonable Efforts to obtain the right under any agreement with a Third Party providing for the Manufacture or distribution of the Product to assign such agreement to Checkpoint, or at Checkpoint’s election, to Licensor or any Affiliate of Licensor, upon termination of this Agreement in the circumstance where the provisions of Section 10.7 are applicable. TGTX shall or shall cause all Manufacturing to be done in accordance with cGMP and applicable Law.

3.7 Marketing. Following receipt of Marketing Approval for a Licensed Product in a jurisdiction in the Territory in and for the Field and during the remainder of the Term:

(a) TGTX shall be solely responsible to Market the Licensed Product in and for the Field in the Territory using Commercially Reasonable Efforts. As used in this Section, “TGTX” includes its Affiliates and Sublicensees.

(b) At least once per calendar year following the first Regulatory Approval of a Licensed Product in a jurisdiction, TGTX shall provide to licensor a high level written status report summarizing the material Marketing activities conducted by TGTX and its Affiliates (but not its Sublicensees) pertaining to the Licensed Product in and for the Field.

ARTICLE IV
LICENSOR RESEARCH

4.1 Overview. As part of the License Agreement, Licensor and Checkpoint entered into a research project (the “Research Project”) described in Schedule 4 hereto (the “Work Plan”), whereby the Licensor agreed to use Commercially Reasonable Efforts to conduct and complete the Research Project in accordance with the timeline set forth in the Work Plan. Upon completion of all of the tasks set forth in the Work Plan, Licensor shall deliver to Checkpoint, and Checkpoint shall deliver to TGTX, the deliverables set forth in the Work Plan. All Licensor Know-How generated in connection with such Research Project shall be delivered to TGTX within thirty (30) days following its receipt from the Licensor and shall deemed Licensor Know-How sublicensed to TGTX hereunder.

4.2 Payment. Fees and expenses incurred by Checkpoint for Licensor’s performance of the Research Project, which are outlined in the Work Plan, shall be Shared Development Expenses and borne 50% by Checkpoint and 50% by TGTX.

4.3 Status. Checkpoint shall promptly provide to TGTX all Licensor written reports received by Checkpoint regarding the deliverables provided in the Work Plan and use reasonable efforts to keep TGTX updated on the status of the work and deliverables.

4.4 Research Inventions. Notwithstanding anything to the contrary contained in the Work Plan, Licensor shall own all right, title and interest in and to the Research Inventions, including, without limitation, all Research Patents and all other intellectual property rights appurtenant to the Research Inventions. Research Patents shall be Licensor Patents and come within the ambit of the license of Section 4.1.

ARTICLE V
Financial Provisions

5.1 License Fee. TGTX shall pay to Checkpoint a non-refundable, non-creditable license fee of one million U.S. dollars ($1,000,000) within thirty (30) days of the Effective Date. As of the Effective Date, there are no pending performance obligations on Checkpoint to receive the license fee.

5.2 Milestone Payments. TGTX shall, with respect to the first Licensed Product to achieve a milestone event below (a “Milestone”), pay to Checkpoint the respective non-refundable and non-creditable milestone payment (“Milestone Payment”) under the column “First Achievement Milestone Payment” within twenty (20) days following TGTX’s receipt of actual knowledge of such achievement. In the event a Milestone (other than the first Milestone listed below) is achieved by a Second Licensed Product (as defined below), TGTX shall pay to Checkpoint the respective milestone payment under the column “Second Product Milestone Payment” within twenty (20) days following TGTX’s receipt of actual knowledge of such achievement. For avoidance of doubt, each Milestone Payment in the table below shall only be paid once under this Agreement, regardless of the number of times such Milestone may be achieved. “Second Licensed Product” means, with respect to a Milestone, a Licensed Product containing a Compound that was not contained in the Licensed Product that first achieved such Milestone. For clarity, with respect to each Milestone, a Second Product Milestone cannot be triggered by a Licensed Product containing the same Compound that achieved the respective First Achievement Milestone, even if for a different indication. By way of further clarification, with respect to a Licensed Product contained in a Combination Product, the Net Sales that trigger the Milestone Payment will be that portion of Net Sales attributable to the Licensed Product as provided in the definition of “Net Sales”. Notwithstanding the table below, upon achievement of a Development Milestone, payments for such Development milestone and all prior Development Milestones shall be due and payable to the extent not already paid.

Milestone Event	First Achievement Milestone Payment	Second Product Milestone Payment
1. ^*.	$^*	N/A
2. ^*.	$^*	$^*
3. ^*	$^* (subject to the below)	$^*
4. ^*	$^*	$^*
5.	$^*	$^*
6. ^*	$^*	$^*
7. ^*	$^*	$^*
8. ^*	$^*	$^*
9. ^*	$^*	$^*
10. ^*.	$^*	$^*
11. ^*.	$^*	$^*
12. ^*.	$^*	$^*

Within twenty (20) days of achieving a Milestone, TGTX shall provide written notice to Checkpoint of such achievement. If at any time Checkpoint disputes whether a Development Milestone has been achieved, the matter shall be referred for resolution in accordance with Section 11.2 as a Technical Dispute.

In the event that TGTX achieves Milestone 3 set forth above, and Checkpoint, in its discretion, determines that, as a result, it can proceed immediately to ^* with respect to Checkpoint’s Development outside of the Field, or if both parties co-sponsor ^* meeting Milestone 3 set xxxx above, then TGTX’s First Achievement Milestone Payment in Milestone 3 shall be reduced in half to $^*.

5.3 Royalty Payments for Licensed Product.

(a) In addition to those payments due to Checkpoint under 5.1 and 5.2 above, TGTX shall pay to Checkpoint a royalty at a rate of ^* percent (^*%) on the Calendar Year, worldwide aggregate Net Sales of all Licensed Products during the Licensed Product-by-Licensed Product and country-by-country Royalty Terms by TGTX and its Affiliates and Sublicensees (but excluding Net Sales of a given Licensed Product in a given country after its applicable Royalty Term).

(b) On a Licensed Product-by-Licensed Product and country-by-country basis upon expiration of the Royalty Term, for a Licensed Product in a country, the rights, licenses and sublicenses granted to TGTX hereunder with respect to such Licensed Product in such country shall continue in effect but become exclusive fully paid-up, royalty-free, transferable (to the extent not transferable previously), perpetual and irrevocable, provided that TGTX shall remain liable for any unpaid Milestone Payments and any royalty payments previously owed or accrued. For the avoidance of doubt, in a country where no Licensor Patent containing a Valid Claim covering a Licensed Product has ever existed nor ever exists, no royalties shall be due.

^* Confidential material redacted and filed separately with the Commission.

5.4 Timing of Payment. Payments in the nature of royalties payable under Section 5.3(a) shall be payable on actual Net Sales and shall accrue at the time provided therefor by GAAP. Payments in the nature of royalty obligations that have accrued during a particular Calendar Quarter shall be paid, on a Calendar Quarter basis, within 45 days after the end of each Calendar Quarter commencing with the Calendar Quarter in which the First Commercial Sale occurred.

5.5 Royalty Reports and Records Retention. Within forty-five (45) days after the end of each Calendar Quarter during which Licensed Products have been sold, TGTX shall deliver to Checkpoint, together with the applicable royalty/payment in the nature of royalties payment due, a written report, on a Licensed Product-by-Licensed Product and country-by-country basis, of Net Sales for such Calendar Quarter. Such report shall (i) total Net Sales for each Licensed Product and Combination Product (including an itemization of the deductions applied to such gross sales to derive such Net Sales and if a Licensed Product is part of a Combination Product the percentage of the Combination Product’s Net Sales attributed to the Licensed Product) during the relevant Calendar Quarter, in each case on a dosage-by-dosage, country-by-country basis, including a summary of currency exchange rates used in the calculations, and (ii) the calculation of royalties due on the foregoing. In addition for any Sublicense, the report shall provide the information in clauses (i) through (ii) above. Such report shall be deemed “Confidential Information” of TGTX subject to the obligations of Article VII of this Agreement. For three years after each sale of a Licensed Product, TGTX shall keep (and shall cause its Affiliates and Sublicensees to keep) complete and accurate records of such sale in sufficient detail to confirm the accuracy of the royalty or royalty/payment in the nature of royalties calculations hereunder.

5.6 Audits.

(a) Upon the written request of Checkpoint, and not more than once in each Calendar Year, TGTX shall permit an independent certified public accounting firm (“Auditors”) of nationally recognized standing selected by Checkpoint and reasonably acceptable to TGTX, at Checkpoint’s expense, to have access to and to review, during normal business hours upon reasonable prior written notice, the applicable records of TGTX and its Affiliates or Sublicensees to verify the accuracy of the royalty reports and the Milestone Payments for Milestones which are not Development Milestones. Such review may cover: (i) the records for sales made in any Calendar Year ending not more than three years before the date of such request, and (ii) only those periods that have not been subject to a prior audit. The accounting firm shall disclose to Checkpoint only whether the royalty reports and Milestone Payments are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Checkpoint by the Auditors. This right to audit shall remain in effect during the Term of this Agreement and for a period of two (2) years after the termination of this Agreement.

(b) If such accounting firm concludes that additional royalties or Milestone Payments were owed during such period, TGTX shall pay the additional royalties and Milestone Payments within 20 days after the date such public accounting firm delivers to TGTX such accounting firm’s written report. If such accounting firm concludes that an overpayment was made, such overpayment shall be fully creditable against amounts payable in subsequent payment periods or at TGTX’s request, shall be reimbursed to TGTX within 30 days after the date such public accounting firm delivers such report to TGTX. Checkpoint shall pay for the cost of any audit by Checkpoint, unless TGTX has underpaid Checkpoint by $50,000 or more for a specific royalty period, in which case TGTX shall pay for the reasonable costs of audit.

(c) Each Party shall treat all information that it receives under this Section 5.6 in accordance with the confidentiality provisions of Article VII of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the audited Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement, except to the extent necessary for a Party to enforce its rights under the Agreement.

5.7 Mode of Payment and Currency. All payments to Checkpoint under this Agreement, whether or not in respect of Net Sales or milestone events, shall be made by deposit of U.S. Dollars in the requisite amount to such bank account as Checkpoint may from time to time designate by advance written notice to TGTX. Conversion of sales or expenses recorded in local currencies to Dollars will be performed in a manner consistent with TGTX’s normal practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates. These practices are set forth on Schedule 5 attached hereto. Based on the resulting Net Sales in U.S. Dollars, the then applicable royalties/payment in the nature of royalties shall be calculated.

5.8 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at a rate equal to the lesser of (a) U.S. Dollar one-month LIBOR as of the date such payment was due (taken from a widely accepted source of published interest rates), plus three (3) percentage points, or (b) the maximum rate permissible under applicable Law. Accrual and payment of interest shall not be deemed to excuse or cure breaches of contract arising from late payment or nonpayment.

5.9 Taxes. All amounts due hereunder exclude all applicable sales, use, and other taxes and duties, and TGTX shall be responsible for payment of all such taxes (other than based on Checkpoint’s income) and duties and any related penalties and interest, arising from the payment of amounts due under this Agreement. The Parties agree to cooperate with one another and use Commercially Reasonable Efforts to avoid or reduce tax withholding or similar obligations in respect of payments in the nature of royalties, Milestone Payments, and other payments made by TGTX to Checkpoint under this Agreement. To the extent TGTX is required to withhold taxes on any payment to Checkpoint, TGTX shall pay the amounts of such taxes to the proper governmental authority in a timely manner and promptly transmit to Checkpoint official receipts issued by the appropriate taxing authority and/or an official tax certificate, or such other evidence as Checkpoint may reasonably request, to establish that such taxes have been paid. Checkpoint shall provide TGTX any tax forms that may be reasonably necessary in order for TGTX to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Checkpoint shall use Commercially Reasonable Efforts to provide any such tax forms to TGTX at least 45 days before the due date for any payment for which Checkpoint desires that TGTX apply a reduced withholding rate. Each Party shall provide the others with reasonable assistance to enable the recovery, as permitted by applicable law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax. Notwithstanding the foregoing, if TGTX transfers or sublicenses any rights under this Agreement, Drug Approval Applications or Regulatory Approvals, Development Inventions or relocates or assigns this Agreement and as a result TGTX or its assignee is required to withhold or deduct any taxes by any government outside the United States, any subdivision thereof, or any other governmental unit within the territory of such government (such taxes collectively referred to as “Charges”), in excess of Charges that Checkpoint would otherwise be required to pay had such transfer, relocation, or assignment not been made, or Checkpoint is required to pay any Charge imposed by any government outside the United States in excess of Charges that Checkpoint would otherwise be required to pay had such transfer or assignment not been made, TGTX shall pay such additional amounts so that payments received by Checkpoint net of all Charges, shall equal the amount to which Checkpoint would have been entitled had there been no such Charges, provided, however that TGTX shall have no obligation to pay any additional amount to the extent that the Charges are imposed by reason of Checkpoint failing to provide a form or similar other evidence reasonably requested by TGTX that would allow for a reduction or exemption of such Charges that Checkpoint is legally able to provide (including, for the avoidance of doubt, Checkpoint’s qualification for the benefit of an applicable income tax convention).

ARTICLE VI
Inventions and Patents

6.1 Patent Prosecution and Maintenance.

(a) Patents. TGTX shall reimburse Checkpoint up to $25,000 in expenses (including attorney’s fees) paid by Checkpoint to Licensor for filing of patent applications (national, international or PCT) included in the Licensor Patents and filed prior to the Effective Date within thirty (30) days of receipt of Checkpoint’s invoice for such expenses. As between TGTX and Checkpoint, Checkpoint shall be solely responsible for Patent Prosecution of the Licensor Patents in the Territory. Checkpoint shall keep TGTX informed of material actions with respect to the filing and prosecution of Licensor Patents or related proceedings (e.g. interferences, oppositions, reexaminations, reissues, revocations or nullifications) in a timely manner, and shall reasonably consider the advice of TGTX and its patent counsel, and Checkpoint will authorize its patent counsel to speak directly with TGTX and its counsel. Checkpoint shall not abandon prosecution or maintenance of any Licensor Patent in the Territory without first notifying TGTX in a reasonably timely manner of Checkpoint’s intention and reason therefor, and providing TGTX with reasonable opportunity to consider to assume, with no obligation to do so, responsibility for prosecution and maintenance of such Licensor Patent in the Territory as set forth in Section 6.1(b). TGTX shall reimburse Checkpoint for 50% of the reasonable out-of-pocket expenses incurred by Checkpoint in filing, prosecuting and maintaining the Licensor Patents in the Territory. Payments are due within thirty (30) days of receipt of Checkpoint’s invoice for such expenses.

(b) Abandonment. If Checkpoint provides TGTX with written notification that it will no longer support or pursue the filing, prosecution, or maintenance (“Abandonment” and when uses as a verb “Abandon”) of a specified Licensor Patent in a particular country (an “Abandoned Patent”) in the Territory, then (a) Checkpoint’s responsibility for such filing, prosecution, or maintenance of the Abandoned Patent in such country, and the fees and costs related thereto, will terminate on the earlier of (x) the date forty-five (45) Calendar Days after TGTX’s receipt of such written notice from Checkpoint or (y) TGTX’s assumption of the filing, prosecution and maintenance of such Abandoned Patent in such country at TGTX’s sole expense. If TGTX does not assume the filing, prosecution and maintenance of such Abandoned Patent in such country within forty-five (45) Calendar days after TGTX’s receipt of such written notice from Checkpoint, the specified Abandoned Patent shall no longer be deemed a Licensor Patent hereunder. If Checkpoint Abandons all Licensor Patents in a country in the Territory, without the assumption by TGTX of the filing, prosecution and maintenance of any such Licensor Patent in such country, Licensor by notice to Checkpoint may terminate such country from the License Agreement and such country will become an “Abandoned Terminated Country” under this Agreement. Following Licensor’s notice to Checkpoint, which shall be promptly sent to TGTX, TGTX’s (and its Sublicensees’) rights to any Licensor Patents in such country shall terminate. If TGTX assumes an Abandoned Patent, thereafter TGTX shall be solely responsible for Patent Prosecution of the Abandoned Patent in the Territory. Except as provided below, TGTX shall assume and have sole responsibility for Patent Prosecution for the Abandoned Patent in the Territory. TGTX will, to the extent reasonably practicable, provide Licensor a reasonable opportunity to review and comment on any material patent filings or correspondence with patent authorities pertaining to the Abandoned Patents, provided that all decisions with respect to Patent Prosecution of the Abandoned Patents shall be made by TGTX in its sole reasonable discretion. TGTX shall not abandon prosecution or maintenance of any Abandoned Patent without first notifying Licensor in a reasonably timely manner of TGTX’s intention and reason therefor, and providing Licensor with reasonable opportunity to consider to assume, with no obligation to do so, responsibility for prosecution and maintenance of such Abandoned Patent.

6.2 Certification under Drug Price Competition and Patent Restoration Act. Each of Checkpoint and TGTX shall immediately give written notice to the other of any Paragraph IV Certification.

6.3 Enforcement of Patents.

(a) Notice. If either Party becomes aware of (i) any actual, potential, or alleged infringement of any of the rights to Licensor Patents under this Agreement with respect to Licensed Products in the Field, (ii) misappropriation of any Licensor Know-How that materially adversely affects exploitation of Licensed Products in the Field, or (iii) a Paragraph IV Certification (each of subclauses (i), (ii) and (iii), an “Infringement”) and, such Party shall give to the other Party prompt and reasonably detailed written notice of such actual, potential, or alleged Infringement. Notwithstanding the foregoing, each Party shall notify the other Party within two (2) Business Days of its receipt of, or receipt of notice of, any Paragraph IV Certification. This Section 6.3 sets forth the rights of the Parties to commence and prosecute an action relating to such Third Party Infringement (an “Offensive Enforcement Action”).

(b) Right to Bring an Action for Licensor’s Patents. Checkpoint and Licensor shall have (i) the right, but not the obligation to undertake control of, and manage and prosecute, compromise or settle, including selection of counsel (collectively, “Prosecute”), any Offensive Enforcement Action relating to a Paragraph IV Certification and (ii) the right but not the obligation to Prosecute any other Offensive Infringement Action. If Checkpoint has not exercised their first right to Prosecute a non Paragraph IV Offensive Infringement Action within one hundred twenty (120) days of receipt of notice of the same, or a Paragraph IV Offensive Infringement Action within ten (10) days of receipt of notice of same, Checkpoint shall within five (5) days notify TGTX in writing and TGTX may, by written notice to Checkpoint no later than five (5) days following TGTX’s receipt of notice from Checkpoint, Prosecute such action (either such Party who Prosecutes such action, the “Prosecuting Party”). The non-Prosecuting Party may, in its sole discretion and at its expense, join in any Offensive Infringement Action and in such case shall reasonably cooperate with the Prosecuting Party. At the Prosecuting Party’s request the non-Prosecuting Party shall provide the Prosecuting Party with all relevant documentation (as may be requested by the Prosecuting Party) evidencing that the Prosecuting Party is validly empowered by the non-Prosecuting Party to initiate an Offensive Infringement Action. The non-Prosecuting Party shall be under the obligation to join the Prosecuting Party in its Offensive Infringement Action if the Prosecuting Party determines that this is necessary to demonstrate “standing to xxx”, provided that the Prosecuting Party shall pay the fees (including attorneys’ fees) if the non-Prosecuting Party retains its own counsel. The Prosecuting Party shall have the sole and exclusive right to select counsel for any suit initiated by it pursuant to this Section 6.3 (but not the non-Prosecuting Party’s counsel). Checkpoint’s or TGTX’s rights under this Section may be exercised by their respective Affiliates or in TGTX’s case, Sublicensees.

(c) Costs and expenses of an Action. Subject to Section 6.3(b) and (f), each Party involved in an Action under Section 6.3(b) shall pay its own costs and expenses incurred in connection with such Action.

(d) Settlement. No Party shall settle or otherwise compromise (or resolve by consent to the entry of judgment upon) any Offensive Infringement Action or Patent Prosecution by admitting that any Licensor Patent is to any extent invalid or unenforceable or any settlement (or consent to the entry of a judgment) that entails any payment by the other Party, any license, covenant not to xxx relating to, dedication to the public of, abandonment of, any Licensor Technology or would otherwise grant any rights to Manufacture, use, sell or otherwise commercialize a Competing Product, or materially adversely affect the rights of the other Party, without the other Party’s prior written consent.

(e) Reasonable Assistance. Each Party (if it is not the Party Prosecuting or defending Licensor’s Patent Rights) shall provide reasonable assistance to the other Party, including providing access to relevant documents and other evidence and making its employees and consultants available, subject to the other Party’s reimbursement of any reasonable out-of-pocket expenses incurred on an on-going basis by the non-enforcing or non-defending Party in providing such assistance.

(f) Distribution of Amounts Recovered. Any amounts recovered by the Party initiating an Offensive Infringement Action pursuant to this Section 6.3, whether by settlement or judgment, shall be allocated in the following order: (i) to reimburse the Prosecuting Party for any costs incurred; (ii) to reimburse the non-Prosecuting Party and Licensor for its costs incurred in such Offensive Infringement Action, if it joins (as opposed to taking over) such Offensive Infringement Action; and (iii) the remaining amount of such recovery shall (A) if TGTX (or a Sublicensee) is the Prosecuting Party in the Offensive Infringement Action, the remainder shall be allocated to TGTX and the portion thereof attributable to “lost sales” shall be deemed to be Net Sales for the Calendar Quarter in which the amount is actually received by TGTX and TGTX shall pay to Checkpoint a royalty on such portion based on the royalty rates set forth in Section 5.3(a), and the portion thereof not attributable to “lost sales” shall be allocated to TGTX, (B) if Checkpoint is the Prosecuting Party then the remaining amount of the recovery shall be retained by Checkpoint. and (C) if Licensor is the Prosecuting Party then the remaining amount of the recovery shall be retained by the Licensor.

(g) Irrespective of whether Checkpoint, TGTX or the Licensor decide to take any action under Section 6.3(b), the payment obligations under Section 5 shall remain unaffected.

6.4 Third Party Actions Claiming Infringement.

(a) Notice. If either Checkpoint or TGTX becomes aware of any Third Party Action, such Party shall promptly notify the other of all details regarding such claim or action that is reasonably available to such Party.

(b) Duty to Defend. Subject to the respective indemnity obligations of the Parties set forth in Article IX, TGTX shall have the obligation, at its sole cost and expense, to defend a Third Party Action described in Section 6.4(a) and (subject to Section 6.4(f)) to compromise or settle such Third Party Action. TGTX shall have the sole and exclusive right to select counsel for such Third Party Action.

(c) Consultation. The Party defending a Third Party Action shall be the “Controlling Party”. The Controlling Party shall consult with the non-Controlling Party, pursuant to an appropriate joint defense or common interest agreement, on all material aspects of the defense.

9.3 Procedure.

(a) The Party or other Person intending to claim indemnification under this Article IX (an “Indemnified Party”) shall promptly notify the opposed Party (the “Indemnifying Party”) of any Claim in respect of which the Indemnified Party intends to claim such indemnification (provided, that no delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any liability or obligation under this Agreement except to the extent the Indemnifying Party has suffered actual prejudice directly caused by the delay or other deficiency), and the Indemnifying Party shall assume the defense thereof (with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party) whether or not such Claim is rightfully brought; provided, however, that an Indemnified Party shall have the right to retain its own counsel and to participate in the defense thereof, with the fees and expenses to be paid by the Indemnified Party unless the Indemnifying Party does not assume the defense or unless a representation of both the Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate due to the actual or potential differing interests between them, in which case the reasonable fees and expenses of counsel retained by the Indemnified Party shall be paid by the Indemnifying Party. (Provided, that in no event shall the Indemnifying Party be required to pay for more than one separate counsel no matter the number or circumstances of all Indemnified Parties.)

(b) If the Indemnifying Party shall fail to timely assume the defense of and reasonably defend such Claim, the Indemnified Party shall have the right to retain or assume control of such defense and the Indemnifying Party shall pay (as incurred and on demand) the fees and expenses of counsel retained by the Indemnified Party.

(c) The Indemnifying Party shall not be liable for the indemnification of any Claim settled (or resolved by consent to the entry of judgment) without the written consent of the Indemnifying Party. Also, if the Indemnifying Party shall control the defense of any such Claim, the Indemnifying Party shall have the right to settle such Claim; provided, that the Indemnifying Party shall obtain the prior written consent (which shall not be unreasonably withheld or delayed) of the Indemnified Party before entering into any settlement of (or resolving by consent to the entry of judgment upon) such Claim unless (i) there is no finding or admission of any violation of law or any violation of the rights of any person by an Indemnified Party, no requirement that the Indemnified Party admit negligence, fault or culpability, and no adverse effect on any other claims that may be made by or against the Indemnified Party and (ii) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement does not require the Indemnified Party to take (or refrain from taking) any action.

(d) The Indemnified Party, and its employees and agents, shall cooperate fully with the Indemnifying Party and its legal representatives in the investigations of any Claim.

(e) Regardless of who controls the defense, each Party hereto shall reasonably cooperate in the defense as may be requested.

The insurance shall insure TGTX against all liability related to its activities relating to the Development, Manufacture or sale of Licensed Products subject to this Agreement, subject to the limits set forth above. The insurance above, shall be in amounts that are reasonable and customary in the pharmaceutical industry for the Territory, but in no event shall any TGTX’s liability insurance relating to commercial Manufacture, sale or distribution of a Licensed Product provide coverage less than two million U.S. dollars (U.S. $2,000,000) per occurrence (or claim) and an annual aggregate of two million U.S. dollars (U.S. $2,000,000). Policies for the Development, commercial Manufacture, sale or distribution of a Licensed Product shall include a contractual endorsement naming Checkpoint and Licensor as an additional insured in relation to liabilities arising from its obligations under the terms of this Agreement and require the insurance carriers to provide Checkpoint with no less than thirty (30) days’ written notice of any change in the terms or coverage of the policies or their cancellation.

ARTICLE X
TERM AND TERMINATION

10.1 Term and Expiration. The term of this Agreement shall commence on the Effective Date and, unless earlier terminated as provided in this Article X, shall continue in full force and effect, on a country-by-country and Licensed Product-by-Licensed Product basis until the Royalty Term in such country with respect to such Licensed Product expires, at which time this Agreement shall expire in its entirety with respect to such Licensed Product in such country (the “Term”).

10.2 Termination upon Material Breach. If a Party breaches any of its material obligations under this Agreement (a “Material Breach”), the other Party may give to the breaching Party a written notice specifying the nature of the Material Breach, requiring it to cure such Material Breach, and, if desired, stating its intention to terminate this Agreement if such Material Breach is not cured. If such Material Breach is not capable of being cured, or is capable of being cured but nonetheless has not within 60 days after the receipt of such notice been cured, then the non-breaching Party (in addition to and not in lieu of all other available rights and remedies) be entitled to at its option either (a) terminate this Agreement immediately by written notice to the other Party, or (b) continue this Agreement in full force and effect and seek any legal or equitable remedies that the non-breaching Party may have.

10.3 Termination for Insolvency. Either Party (i.e., the non-insolvent Party) may terminate this Agreement, if, at any time, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially all of its assets, or if the other Party proposes a written agreement of composition or extension of substantially all of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or if the other Party shall propose or be a party to any dissolution or liquidation, or if the other Party shall make an assignment of substantially all of its assets for the benefit of creditors.

10.4 Termination for Patent Challenge. Checkpoint will be permitted to terminate this Agreement by written notice effective upon receipt if TGTX or its Affiliates or its Sublicensees, directly or indirectly through assistance granted to a Third Party, commence any interference or opposition proceeding, challenge in a legal or administrative proceeding the validity or enforceability of, or oppose in a legal or administrative proceeding any extension of or the grant of a supplementary protection certificate with respect to, any Licensor Patents (a “Patent Challenge”). TGTX will include provisions in all agreements granting Sublicenses of TGTX’s rights hereunder (other than agreements with manufacturers, services providers, distributors and other agents) providing that if the Sublicensee or its Affiliates undertake a Patent Challenge with respect to any Licensor Patents under which the Sublicensee is Sublicensed, TGTX will be permitted to terminate such Sublicense agreement. If a Sublicensee of TGTX (or an Affiliate of such Sublicensee) undertakes a Patent Challenge of any such Licensor Patent Rights under which such Sublicensee is sublicensed, then TGTX upon receipt of notice from Checkpoint of such Patent Challenge will terminate the applicable Sublicense agreement. If TGTX fails to so terminate such Sublicense agreement, Checkpoint may terminate TGTX’s right to Sublicense in the country(ies) covered by such Sublicense agreement and any Sublicenses previously granted in such country(ies) shall automatically terminate. In connection with such Sublicense termination, TGTX shall cooperate with Checkpoint’s reasonable requests to cause such a terminated Sublicensee to discontinue activities with respect to the Licensed Product in such country(ies).

10.5 Termination for Convenience. This Agreement may be terminated by TGTX at any time for its convenience upon sixty (60) days prior written notice to Checkpoint.

10.6 Termination for Suspension of Development. If prior to Regulatory Approval of a Licensed Product, TGTX or its Affiliates provides Notice of Termination or Suspension, then Checkpoint may terminate this Agreement on thirty (30) days’ notice to TGTX.

10.7 Termination for Good Scientific Reason. TGTX may terminate this Agreement with respect to any specific Compound and the related Licensed Product upon sixty (60) days’ prior written notice to Checkpoint if (i) such Compound or Licensed Product has an adverse safety profile or causes serious adverse reactions; or (ii) TGTX reasonably determines that such Licensed Product will not qualify for Regulatory Approval in the United States.

10.8 Termination for Abandonment. If Checkpoint Abandons all Licensor Patents in a country, and TGTX does not assume the filing, prosecution and maintenance of such Abandoned Patent in such country, then Checkpoint may terminate the Agreement with respect to such country on thirty (30) days’ written notice to TGTX.

(2) TGTX shall, to the extent transferable, assign and transfer to Checkpoint all of its and its Affiliates’ right, title and interest in and to all Regulatory Approvals and Drug Approval Applications and Regulatory Filings that it solely owns, prepared (whether completed or partially completed), filed and/or granted solely for terminated Compounds and Covered Products in such Terminated Country(ies), and TGTX shall promptly file with any applicable Regulatory Authority notice of such transfer and assignment;

(3) TGTX shall, to the extent of its Control, transfer to Checkpoint all relevant records and materials in TGTX’s possession containing Confidential Information relating solely to the terminated Compounds and Covered Product in such Terminated Country(ies), provided, however, that TGTX may keep one copy of such Confidential Information for archival purposes only and such Confidential Information shall be Confidential Information of Checkpoint;

(4) To the extent TGTX solely owns any right, title and interest in any Trademarks, trade names and/or logos under which only the terminated Covered Product has been or is being marketed or sold in the Terminated Country(ies) (excluding for avoidance of doubt the TGTX’s or its Affiliates corporate Trademarks), or internet domain registrations for any such Trademarks or tradenames (excluding for avoidance of doubt domain name registrations incorporating the TGTX’s or its Affiliates corporate Trademarks (in whole or in part)), TGTX shall assign the same to Checkpoint;

(i) if the termination occurs before completion (where “completion” means receipt of a final study report meeting the guidelines of the International Conference on Harmonization) of a Phase III Study for a Licensed Product, then ^* percent (^*%) royalty on Net Sales;

(ii) if the termination occurs after completion (where “completion” means receipt of a final study report meeting the guidelines of the International Conference on Harmonization) of a Phase III Study for a Licensed Product but before approval of an NDA or BLA for such Licensed Product in such country, then a ^*percent (^*%) royalty on Net Sales; or

For purposes of this Section 10.9(c), the definition of “Net Sales,” and Sections 5.4 through 5.9 shall apply mutatis mutandis to the calculation, payment, recording, and auditing of Checkpoint’s obligations to pay Reverse Royalties under this Section 10.9 as they apply to TGTX and, solely for such purpose, each reference in each such Section (and any related definitions) to TGTX shall be deemed to be a reference to Checkpoint, and (y) a Sublicensee shall be deemed to be a reference to a licensee or sublicensee of Checkpoint or any of its Affiliates (and expressly excluding Existing Sublicensees) with respect to the Licensed Product. Notwithstanding the foregoing, no Reverse Royalty shall be due or payable by Checkpoint relating to Net Sales of Sublicensees under any Sublicense in effect at the date of termination of this Agreement (Sublicensees under such Sublicenses, “Existing Sublicensees”). “Sublicensing Royalty Revenue” means sales-based royalties, and minimum sales royalties, each as actually received by Checkpoint or its Affiliate from an Existing Sublicensee as consideration for the grant of rights to Patent Rights.

In no event shall Checkpoint transfer (i) its, right, title or interest in Patent Rights Covering a terminated Compound or Licensed Product or (ii) any of the Transferred Assets, unless the assignee assumes Checkpoint’s obligations to pay royalties under this Section 10.9 pursuant to a commercially reasonable assignment and assumption agreement providing that (x) TGTX is a third party beneficiary to such agreement for the purpose of enforcing such payment obligations and (y) any further assignment by such assignee is subject to the requirements set forth in this paragraph.

(d) Articles I (Definitions), VI (Patents and Infringement), VII (Confidentiality), IX (Indemnification; Limitation of Liability; Insurance), XI (Dispute Resolution) and XII (Miscellaneous Provisions) and Section 2.5 (but only with respect to TGTX in connection with a termination under Section 10.8), Sections 5.1, 5.3(b), 5.5 (Royalty Reports and Records Retention), 5.6 (Audits), 5.8 (Late Payments), 5.9 (Taxes) and 10.9 (Effects of Termination/Expiration) hereof shall survive the expiration or termination of this Agreement for any reason. A termination of any Compound from this Agreement shall also terminate the related Licensed Product and termination of any Licensed Product shall terminate the related Compound

(e) Termination or expiration of this Agreement shall not relieve the Parties of any liability that accrued hereunder before the effective date of such termination or expiration. In addition, termination or expiration of this Agreement shall not preclude either Party from pursuing all rights and remedies it may have hereunder or at Law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation.

(f) Effect on Sublicenses.

(i) Upon the termination of this Agreement in its entirety, each Sublicense which provides for its survival upon such termination shall survive such termination (but in no event for longer than the period TGTX’s licenses hereunder would have been in effect had termination not occurred) and remain in full force and effect, with Checkpoint or upon Checkpoint’s election, to Licensor or an Affiliate of Licensor, as the Sublicensee’s direct licensor solely with respect to the Licensor Technology (“Surviving Sublicense”). Upon Checkpoint’s written request, provided that a Surviving Sublicense does not include licenses to products other than Licensed Products, TGTX shall assign a Surviving Sublicense to Checkpoint or upon Checkpoint’s election, to Licensor or an Affiliate of Licensor. If a Surviving Sublicense includes licenses to products other than Licensed Products, TGTX shall require that the terms of such Surviving Sublicense permits the assignment in part to Checkpoint or upon Checkpoint’s election, to Licensor or an Affiliate of Licensor, relating to the Licensor Technology and shall, upon Checkpoint’s written request, assign to Checkpoint or upon Checkpoint’s election, to Licensor or an Affiliate of Licensor, the portion of such Surviving Sublicense pertaining to the Licensor Technology.

(ii) Upon the termination of this Agreement with respect to a Terminated Product in a Terminated Country, each Sublicense that includes such Terminated Product in such Terminated Country which provides for its survival upon such termination shall survive such termination (but in no event for longer than the period TGTX’s licenses hereunder would have been in effect had termination not occurred) and remain in full force and effect, with (i) Checkpoint or upon Checkpoint’s election, Licensor or an Affiliate of Licensor, as the Sublicensee’s direct licensor solely with respect to the Licensor Technology and the portion of such Sublicense that includes such Terminated Product in such Terminated Country (“Surviving Partial Sublicenses”) and (ii) TGTX continuing as the Sublicensee’s direct licensor with respect to all other rights granted under such Sublicense. Upon such termination, Checkpoint and Licensor shall be third party beneficiaries of the Surviving Partial Sublicense with respect to the portion thereof pertaining solely to the Terminated Products in the Terminated Countries. Each Sublicense that provides for survival as set forth in this Section shall provide for such third party beneficiary status.

(iii) With respect to each Surviving Sublicense and Surviving Partial Sublicense, in the absence of written notice from Checkpoint to a Sublicensee under a Surviving Sublicense or Surviving Partial Sublicense provided within forty five (45) days of the termination of this Agreement electing to continue the payment terms under such Sublicense, in which case such Sublicense payment terms shall continue, the Sublicensee’s payment obligations with respect to its exercise of its surviving rights to the Licensor Technology (but not with respect to its exercise or enjoyment of any other rights or assets) thereunder shall, in lieu of any payment obligations set forth in the Sublicense, be the corresponding payment obligations set forth in this Agreement, provided that (a) with respect to Milestone Payments under such Sublicense where such Sublicense is for less than the entire Territory and the Milestone Payment is based on cumulative worldwide Net Sales, the portion of such Milestone Payment for which such Sublicensee shall be liable shall be such Milestone Payment multiplied by: (I) cumulative Net Sales in such Sublicensee’s territory (and not worldwide Net Sales) divided by (II) cumulative worldwide Net Sales and (b) with respect to royalties payable under such Sublicense, if the royalty set forth in such Sublicense is equal to or greater than five percent (5%) of such Sublicensee’s Net Sales, then such amount shall be payable under such Sublicense in accordance with the terms thereof (in lieu of any royalty payments pursuant to the terms of Section 5.3(a)), and if such royalty is less than five percent (5%) of such Sublicensee’s Net Sales, then the royalty payable under such Sublicense shall be the amounts set forth in Section 5.3(a) (in lieu of any royalty payments pursuant to the terms of such Sublicense) and the royalty tiers will, for the avoidance of doubt, be achieved based on worldwide Net Sales as calculated in accordance with this Agreement, and Checkpoint shall notify such Sublicensee within thirty (30) days following it becoming aware of a Net Sales tier higher than the then-current Net Sale tier applying to the calculation of royalties pursuant to Section 5.3(a). Notwithstanding the foregoing, within thirty (30) days after the effective date of termination of this Agreement, Checkpoint shall have the right to terminate a Sublicense granted to an Affiliate of TGTX.

(g) Termination of the License Agreement.

(i) Upon the termination of the License Agreement in its entirety, this Agreement will remain in full force and effect, with Licensor as TGTX’s direct licensor solely with respect to the Licensor Technology (“Surviving Agreement”), and in the event of such a termination of the License Agreement, Checkpoint has the right to assign, in whole or in part, the Surviving Agreement to Licensor.

(ii) Upon the termination of the License Agreement with respect to a Terminated Product in a Terminated Country, this Agreement will remain in full force and effect, with (i) Licensor as TGTX’s direct licensor solely with respect to the Licensor Technology and the portion of this Agreement that includes such Terminated Product in such Terminated Country (“Surviving Partial Agreement”) and (ii) Checkpoint continuing as TGTX’s direct licensor with respect to all other rights granted under such Surviving Partial Agreement. Upon such termination, Licensor shall be a third party beneficiary of the Surviving Partial Agreement with respect to the portion thereof pertaining solely to the Terminated Products in the Terminated Countries.

(iii) With respect to the Surviving Agreement and Surviving Partial Agreement, the payment terms under this Agreement will continue, except that payment with respect to the Licensed Products will be made directly to Licensor and not Checkpoint.

ARTICLE XI
DISPUTE RESOLUTION

11.1 General. Checkpoint and TGTX shall endeavor to resolve any claim or controversy arising out of the threatened breach, breach, enforcement, interpretation, termination or validity of this Agreement informally by good faith negotiation between the senior executives, officers or management of Checkpoint and TGTX. Either Party may give the other Party written notice of any claim or controversy not resolved in the normal course of business (the “Disputing Party Notice”). Within thirty (30) calendar days after the delivery of the Disputing Party Notice, the receiving Party shall submit to the other Party a written response (the “Response”). The Disputing Party Notice and Response shall include a statement of each Party’s position and a summary of the arguments supporting that position. Within thirty (30) days after the Disputing Party Notice, such designated senior executives, officers or management of Checkpoint and TGTX shall meet at a mutually acceptable time and place and thereafter as often as they reasonably deem necessary to attempt to resolve the claim or controversy. If such efforts do not result in mutually satisfactory resolution of the dispute, the matter shall be referred to the chief executive officers of Checkpoint and TGTX, or their designees. The chief executive officers, or their designees, as the case may be, shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner for up to thirty additional (30) days, or such longer period of time to which the chief executive officers may agree. All negotiations pursuant to this Article 11 are confidential and without prejudice and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence. If the chief executive officers, or their designees, as the case may be, are unable to determine a resolution in the time frame set forth above, the matter may be resolved through arbitration in accordance with the provisions set forth in Section 11.2, in the event of a Technical Dispute or Section 11.3, in the event of other disputes, as applicable, upon notice by a Party on the other Party specifically requesting such arbitration. This Article 11 shall not prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event of a breach or prospective breach of this Agreement by any Party which would cause irreparable harm to the other Party.

11.2 Technical Disputes. In the event a dispute over (i) whether a Milestone has been achieved, (ii) whether TGTX has used Commercially Reasonable Efforts to Develop the Licensed Product, (iii) the proper allocation of Net Sales to a Licensed Product where the Licensed Product is sold as part of a Combination Product, or (iv) the Combination Percentage (each, a “Technical Dispute”) is not resolved in accordance with the negotiation and mediation dispute resolution processes described in Section 11.1 above, then either Party may submit the matter to expert intervention in accordance with this Section 11.2. Any such intervention may be initiated by a Party by written notice to the other Party specifying the subject of the requested intervention. The Technical Dispute hearings shall be convened in New York, New York and shall be resolved by one expert, to be mutually selected by the Parties; or if the Parties fail to agree on the expert within ten (10) business days following the date of such written notice, then the Parties shall cause their respective nominees to select a third individual within ten (10) business days to serve as the expert (the “Expert”). The Expert shall be required to have pharmaceutical industry experience specifically related to conducting formulation development activities and clinical trials, and shall not be any employee, agent or consultant of any Party or an Affiliate of any Party at such time, or otherwise involved (whether by contract or otherwise) in the affairs of any Party at such time. Each Party simultaneously shall submit to the Expert its proposal with respect to its position on the resolution of the Technical Dispute without having seen the other Party’s proposal, along with a discussion document explaining the rationale therefor. The Expert shall have the right to meet with the Parties, either alone or together, and shall have the right to request additional information and documents from each Party. The Expert shall select only one of the Parties’ proposals based on the Expert’s determination of which proposal is more consistent with the Expert’s opinion on the resolution of the Technical Dispute (and consistent with the terms of this Agreement), and shall provide a brief written rationale for such selection. The Expert’s decision shall be final and shall be binding upon the Parties under this Agreement. The Parties shall submit their documentation to the Expert within fifteen (15) days of selection of the Expert and provide any requested additional information and documents within ten (10) days of such request. The Expert shall make his or her decision within fifteen (15) days of such submission (extended by the Expert in his discretion to provide adequate time to review requested documents but in no event shall the decision be made more than thirty (30) days after submission).

11.3 Other Disputes. Where a Party has served a written notice upon the other requesting arbitration of a dispute that is not subject to Section 11.2, any such dispute shall be submitted to final and binding arbitration under the then current commercial arbitration rules of the American Arbitration Association (the “AAA”) in accordance with this Section 11.3. The place of arbitration of any dispute shall be New York, New York. Such arbitration shall be conducted by one (1) arbitrator mutually agreed by the Parties but if such agreement cannot be reached within ten (10) days of the commencement of the arbitration, then an arbitrator appointed by the AAA. The arbitrator shall be a person with relevant experience in the pharmaceutical industry. The arbitration proceeding shall be held as soon as practicable but in any event within ninety (90) days of appointment of the arbitrator. Any award rendered by the arbitrators shall be final and binding upon the Parties. Judgment upon any award rendered may be entered in any court having jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement, as the case may be. The arbitrator shall render a formal, binding, non-appealable resolution and award as expeditiously as possible, but not more than thirty (30) days after the hearing. Each Party shall pay its own expenses of arbitration, and the expenses of the arbitrator shall be equally shared between the Parties unless the arbitrators assess as part of their award all or any part of the arbitration expenses of a Party (including reasonable attorneys’ fees) against the other Party. A Party may make application to the Arbitrator for the award and recovery of its fees and expenses (including reasonable attorneys’ fees).

ARTICLE XII
MISCELLANEOUS PROVISIONS

12.1 Relationship of the Parties. Nothing in this Agreement is intended or shall be deemed to constitute a partnership, agency, joint venture or employer-employee relationship between the Parties. No Party shall have any right or authority to commit or legally bind any other Party in any way whatsoever including, without limitation, the making of any agreement, representation or warranty and each Party agrees to not purport to do so.

12.2 Assignment. Neither Party may assign this Agreement, or any of its rights or obligations hereunder without the other Party’s prior written consent, provided that each Party will, notwithstanding anything to the contrary, be entitled, without the other Party’s prior written consent, to assign or transfer this Agreement: (i) in connection with the transfer or sale of all or substantially all of such Party’s assets or business (or that portion thereof related to the subject matter of this Agreement) to a Third Party, (ii) in the event of such Party’s merger, consolidation, reorganization, with or into a Third Party, change of control or similar transaction, with a Third Party, or (iii) to an Affiliate of such Party, provided that in the case of an assignment to an Affiliate, the assigning Party shall remain primarily liable for the obligations of such Affiliate except where the non-assigning Party provided its prior written consent to such assignment, such consent to not be unreasonably withheld or delayed (in which case the assigning Party shall not remain primarily liable). Any permitted assignee of either Party will, as a condition to such assignment, assume all obligations of its assignor arising under this Agreement following such assignment. Any purported assignment by a Party of this Agreement, or any of such Party’s rights or obligations hereunder, in violation of this Section 12.2 will be void ab initio.

12.3 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments and to do all such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

12.4 Force Majeure. Except for TGTX’s obligation to pay the agreed amounts to Checkpoint, no Party shall be liable to any other Party or be deemed to have breached or defaulted under this Agreement for failure or delay in the performance of any of its obligations under this Agreement (other than obligations for the payment of money) for the time and to the extent such failure or delay is caused by or results from acts of God, earthquake, riot, civil commotion, terrorism, war, strikes or other labor disputes, fire, flood, failure or delay of transportation, omissions or delays in acting by a governmental authority, acts of a government or an agency thereof or judicial orders or decrees or restrictions or any other like reason which is beyond the control of the respective Party (a “Force Majeure Event”). The Party affected by force majeure shall provide the other Party with full particulars thereof as soon as it becomes aware of the same (including its best estimate of the likely extent and duration of the interference with its activities), and shall use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of its obligations hereunder as soon as practicable, and the time for performance shall be extended for a number of days equal to the duration of the force majeure. The Party not subject to the Force Majeure Event may terminate this Agreement if such Force Majeure Event exists for 90 days in any 365-day period on ten (10) days’ notice to the other Party.

12.5 Entire Agreement of the Parties; Amendments. This Agreement and the Schedules hereto constitute and contain the entire understanding and agreement of the Parties respecting the subject matter hereof and cancel and supersede any and all prior or contemporaneous negotiations, correspondence, understandings and agreements between the Parties, whether oral or written, regarding such subject matter (provided, that any and all previous nondisclosure/nonuse obligations are not superseded and remain in full force and effect in addition to the nondisclosure/nonuse provisions hereof). Each Party acknowledges that it has not relied, in deciding whether to enter into this Agreement on this Agreement’s expressly stated terms and conditions, on any representations, warranties, agreements, commitments or promises which are not expressly set forth within this Agreement. No modification or amendment of any provision of this Agreement shall be valid or effective unless made in a writing referencing this Agreement and signed by a duly authorized officer of each Party.

12.6 Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New York, excluding application of any conflict of laws principles. With respect to docketing an arbitration award or seeking injunctive relief, each Party (a) irrevocably submits to the exclusive jurisdiction in the United States District Court for the Southern District of New York located in New York, New York and any State courts sitting in New York, New York (collectively, the “Courts”), and (b) agrees not to raise any objection at any time to the laying or maintaining of the venue of any such action, suit or proceeding in any of the Courts, irrevocably waives any claim that such action, suit or other proceeding has been brought in an inconvenient forum and further irrevocably waives the right to object, that such Courts do not have any jurisdiction over such Party. The United Nations Convention on Contracts for the International Sale of Goods will not apply to this Agreement.

12.7 Notices and Deliveries. All notices required or permitted to be given under this Agreement shall be in writing and shall be deemed given upon receipt if delivered personally or mailed by registered or certified mail (return receipt requested), postage prepaid, or sent by prepaid express courier service, to the Parties at the following addresses (or at such other address for a Party as shall be specified by the notice; provided that notices of a change of address shall be effective only upon receipt thereof):

If to TGTX, addressed to:

TG Therapeutics, Inc
0 Xxxxxxxxxx Xxxxxx, 0^xx Xxxxx

Attention: President

12.8 Waiver. No waiver of any provision of this Agreement shall be valid or effective unless made in a writing referencing this Agreement and signed by a duly authorized officer of the waiving Party. A waiver by a Party of any of the terms and conditions of this Agreement in any instance shall not be deemed or construed to be a waiver of such term or condition for the future, or of any other term or condition hereof.

12.9 Rights and Remedies are Cumulative. Except to the extent expressly set forth herein, all rights, remedies, undertakings, obligations and agreements contained in or available upon violation of this Agreement shall be cumulative and none of them shall be in limitation of any other remedy or right authorized in law or in equity, or any undertaking, obligation or agreement of the applicable Party.

12.10 Severability. This Agreement is severable. When possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Agreement is held to be to any extent prohibited by or invalid under applicable Law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement (or of such provision). The Parties shall make a good faith effort to replace the invalid or unenforceable provision with a valid one which in its economic effect is most consistent with the invalid or unenforceable provision.

12.11 Third Party Beneficiaries. The terms and provisions of this Agreement are intended solely for the benefit of each Party hereto and their respective successors or permitted assigns and it is not the intention of the Parties to confer third-party beneficiary rights upon any other person, including without limitation Sublicensees. If a provision provides a benefit to a Sublicensee or indemnitee, such benefits can only be enforced through a Party or by a separate agreement between such Person and the Party or Parties providing the benefit.

12.12 Equitable Relief. Each Party recognizes that the covenants and agreements herein and their continued performance as set forth in this Agreement are necessary and critical to protect the legitimate interests of the other Party, that the other Party would not have entered into this Agreement in the absence of such covenants and agreements and the assurance of continued performance as set forth in this Agreement, and that a Party’s breach or threatened breach of such covenants and agreements may cause the opposed Party irreparable harm and significant injury, the amount of which will be extremely difficult to estimate and ascertain, thus potentially making any remedy at law or in damages inadequate. Therefore, each Party agrees that an opposed Party shall be entitled to seek specific performance, an order restraining any breach or threatened breach of Article VII or Section 2.5 and all other provisions of this Agreement, and any other equitable relief (including but not limited to temporary, preliminary and/or permanent injunctive relief). This right shall be in addition to and not exclusive of any other remedy available to such other Party at law or in equity.

12.13 Interpretation. The language used in this Agreement is the language chosen by the Parties to express their mutual intent, and no provision of this Agreement shall be interpreted for or against a Party because that Party or its attorney drafted the provision.

12.14 Construction. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” All references herein to Articles, Sections and Schedules shall be deemed references to Articles and Sections of, and Schedules to, this Agreement unless the context shall otherwise require.

12.15 Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original, and all of which together will be deemed to be one and the same instrument. A portable document format (.pdf) copy of this Agreement, including the signature pages, will be deemed an original.
