Net Sales	Royalty Rate
*	* %
*	* %
*	* %

(b) In establishing the royalty/payment in the nature of royalties structure hereunder, the Parties recognize, and TGTX acknowledges, the substantial value of the various obligations being undertaken by Licensor under this Agreement, in addition to the grant of the license under the Licensor Patents, to enable the rapid and effective market introduction of the Licensed Products. The Parties have agreed to the payment structure set forth herein as a convenient and fair mechanism to compensate Licensor for these obligations.

(c) 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 fully paid-up, royalty-free, transferable (to the extent not transferable previously), perpetual and irrevocable.

(d) Subject to the limitation set forth in clause (f) below, if a license to patent rights owned or controlled by a Third Party is necessary, as reasonably determined by TGTX, for TGTX to have freedom to operate under the Licensor Patents to Commercialize the Licensed Product as a monotherapy in the Field and in the Territory, TGTX may obtain such a Third Party license under such patent rights and to deduct from any royalty payments due to the Licensor hereunder an amount equal to * percent ( * %) of any royalty paid by TGTX to such Third Party.

For purposes of this Section, “Generic Product” means a pharmaceutical product that contains the Compound as monotherapy and that is sold in the same country as a Licensed Product by a Third Party that is not a Sublicensee, one of TGTX’s Affiliates, or a Third Party that is otherwise acting on TGTX’s behalf in conducting such sales.

(f) The deduction in the foregoing clause (d) shall be limited in its cumulative application so that no royalty payment hereunder shall be reduced by more than * percent ( * %).

5.5. Timing of Payment. Royalties/payments in the nature of royalties payable under Section 5.4 shall be payable on actual Net Sales and shall accrue at the time provided therefor by US GAAP. Royalty/payment in the nature of royalties obligations that have accrued during a particular Calendar Quarter shall be paid, on a Calendar Quarter basis, within * ( * ) days after the end of each Calendar Quarter during which the royalty/payment in the nature of royalties obligation accrued;provided that within * ( * ) days after the conclusion of each Calendar Year TGTX shall provide notice to Licensor of any adjustments necessary to account for any royalties/payment in the nature of royalties which were overpaid or underpaid for such prior Calendar Year’s Calendar Quarters, and the Parties shall promptly true-up based on such adjustments, provided however, the lapse of such * -day period shall not impact the right of TGTX to credit any over-payments discovered during an audit against future royalties due under Section 5.7 hereof.

5.6. Royalty (Etc.) Reports and Records Retention. Within * ( * ) days after the end of each Calendar Quarter during which Licensed Products have been sold, TGTX shall deliver to Licensor, 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 (a) gross invoiced (or otherwise charged) amounts of sales, by TGTX and its Affiliates and Sublicensees, of Licensed Products subject to royalty payments for such Calendar Quarter, (b) amounts deducted by category (following the definition of Net Sales) from such gross invoiced amounts to calculate Net Sales, (c) Net Sales subject to royalty or royalty/payment in the nature of royalties payments for such Calendar Quarter and Calendar Year to date and (d) the corresponding royalty or royalty/payment in the nature of royalties. Such report shall be deemed “Confidential Information” of TGTX subject to the obligations of Article VII of this Agreement. For * years after each sale of a Licensed Product (whether Covered or not), TGTX shall keep (and shall ensure that its Affiliates and Sublicensees shall 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.

5.7. Audits.

(a) From the First Commercial Sale (of the first Licensed Product to have a First Commercial Sale) until * Calendar Year after the conclusion of the final Royalty Term, upon the written request of Licensor, and not more than * in each * , TGTX shall permit, and shall cause its Affiliates and Sublicensees to permit, an independent certified public accounting firm of nationally recognized standing selected by Licensor (who has not been engaged by Licensor to provide services in any other capacity at any time during the * period before such selection), and reasonably acceptable to TGTX or such Affiliate or Sublicensee, 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 and payment in the nature of royalties reports and payments under this Article V. Such review may cover: (i) the records for sales made in any Calendar Year ending not more than * ( * ) years before the date of such request, and (ii) only those periods that have not been subject to a prior audit.

(b) If such accounting firm concludes that additional royalties and/or royalties/payment in the nature of royalties were owed during such period, TGTX shall pay the additional royalties and/or royalties/payment in the nature of royalties within * ( * ) 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 * ( * ) days after the date such public accounting firm delivers such report to TGTX. If TGTX disagrees with such calculation, TGTX may contest such calculation in writing – at which point the parties will work in good faith to submit the matter to a mediator for resolution. If the parties are unable to reach an agreement via mediation, then TGTX or Licensor may initiate a court action to seek to recover the additional payment or to increase the amount of credit or reimbursement. Licensor shall pay for the cost of any audit by Licensor, unless TGTX has underpaid Licensor by five percent (* %) 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 5.7 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.

5.8. Mode of Payment and Currency. All payments to Licensor under this Agreement, except for payments made in Shares, whether or not in respect of Net Sales or milestone events, shall be made by deposit of US Dollars in the requisite amount to such bank account as Licensor 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. Based on the resulting Net Sales in US Dollars, the then applicable royalties/payment in the nature of royalties shall be calculated.

5.9. 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) US dollar one-month LIBOR, or its official successor, plus * basis 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.

5.10. 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 taxes based on Licensor’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 royalties, payments in the nature of royalties, milestone payments, and other payments made by TGTX to Licensor under this Agreement. To the extent TGTX is required to withhold taxes on any payment to Licensor, TGTX shall pay the amounts of such taxes to the proper governmental authority in a timely manner and promptly transmit to Licensor official receipts issued by the appropriate taxing authority and/or an official tax certificate, or such other evidence as Licensor may reasonably request, to establish that such taxes have been paid. Licensor 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. Licensor shall use Commercially Reasonable Efforts to provide any such tax forms to TGTX at least * ( * ) days before the due date for any payment for which Licensor 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. Licensor shall indemnify and hold TGTX harmless from and against any penalties, interest or other tax liability arising from any failure by TGTX (at the express request of Licensor) to withhold or by reduction (at the express request of Licensor) in its withholding.

TGTX shall have the sole right to determine which of the Licensor Patents, if any, shall be listed for inclusion in the Approved Drug Products with Therapeutic Equivalence Evaluations publication pursuant to 21 U.S.C. Section 355, or any successor Law in the United States, together with any comparable Laws in any other country in the Territory and pertaining to uses within the Field. Licensor will co-operate with TGTX to list any of said Licensor Patents.

6.4. Enforcement of Patents.

(a) Notice. If either Licensor or TGTX believes that a Licensor Patent is being infringed in the Field, or that Licensor Know-How has been misappropriated in the Field, by a Third Party or if a Third Party claims that any Licensor Patent is invalid or unenforceable, the Party possessing such knowledge or belief shall notify the other and provide it with details of such infringement, misappropriation or claim that are known by such Party.

(b) Right to Bring an Action for Licensor’s Patents. If such infringement, misappropriation or claim is in one or more of the Major Markets in respect of Licensor Patents, Licensor shall have the right to attempt to resolve such infringement, misappropriation or claim, including by filing an infringement suit, defending against or bringing a declaratory judgment action as to such claim or taking other similar action (each, “initiation” of an “Action”) and (subject to Section 6.5(e)) to compromise or settle such infringement or claim. * may, in its sole discretion and at its expense, join in any such Action and in such case shall reasonably cooperate with Licensor. If Licensor does not intend to initiate an Action, Licensor shall promptly inform TGTX. If Licensor does not initiate an Action with respect to such an infringement or claim within * ( * ) days following notice thereof, * shall have the right to attempt to resolve such infringement, misappropriation or claim, including by initiating an Action, and (subject to Section 6.5(e)) to compromise or settle such infringement, misappropriation or claim. At TGTX’s request, Licensor shall immediately provide TGTX with all relevant documentation (as may be requested by TGTX) evidencing that TGTX is validly empowered by the Licensor to initiate an Action. Licensor shall be under the obligation to join TGTX in its Action if TGTX determines that this is necessary to demonstrate “standing to ▇▇▇.” The Party initiating such Action shall have the sole and exclusive right to select counsel for any suit initiated by it pursuant to this Section 6.5. If a Party initiates an Action but then elects not to pursue the Action, the other Party shall have the right (but not the obligation) to take over the Action, in which case the second Party shall be deemed to have been the initiating Party.

(c) Costs of an Action. Subject to the respective indemnity obligations of the Parties set forth in Article IX and subject to Section 6.5(f), each Party involved in an Action under Section 6.5(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 Action by admitting that any Licensor Patent is to any extent invalid or unenforceable, or that any Licensor Know-How is not protected or has not been misappropriated, without the other Party’s prior written consent, and, in the case of Licensor, Licensor may not settle or otherwise compromise (or resolve by consent to the entry of judgment upon) an Action in a way that adversely affects or would be reasonably expected to adversely affect any of TGTX’s rights or benefits hereunder with respect to any Licensor Technology or any Licensed Product, without TGTX’s prior written consent.

(e) Reasonable Assistance. Each Party (if it is not the Party enforcing 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 Action pursuant to this Section 6.5, whether by settlement or judgment, shall be allocated in the following order: (i) to reimburse the Party initiating such Action for any costs incurred; (ii) to reimburse the Party not initiating such Action for its costs incurred in such Action, if it joins (as opposed to taking over) such Action; and (iii) the remaining amount of such recovery shall (A) if Licensor initiated the 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 Licensor a royalty on such portion based on the royalty rates set forth in Section 5.4(a), and the portion thereof not attributable to “lost sales” shall be allocated to * % to Licensor and * % to TGTX (B) if Licensor failed to initiate and TGTX initiated the 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 Licensor a royalty on such portion based on the royalty rates set forth in Section 5.4(a), and the portion thereof not attributable to “lost sales” shall be allocated to TGTX.

6.5. Third Party Actions Claiming Infringement.

(a) Notice. If either Licensor 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) Right to Defend. TGTX shall have the right, at its sole expense, but not the obligation, to defend a Third Party Action described in Section 6.6(a) and (subject to Section 6.6(f)) to compromise or settle such Third Party Action. If TGTX declines or fails to assert its intention to defend such Third Party Action within * ( * ) days of receipt/sending of notice under Section 6.6(a), then Licensor shall have the right, at its sole expense, to defend such Third Party Action and (subject to Section 6.6(f)) to compromise or settle such Third Party Action. The Party defending such Third Party Action shall have the sole and exclusive right to select counsel for such Third Party Action.

(c) Consultation. The Party defending a Third Party Action pursuant to Section 6.6(b) 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. The non-Controlling Party shall have a reasonable opportunity for meaningful participation in decision-making and formulation of defense strategy. The Parties shall reasonably cooperate with each other in all such actions or proceedings. The non-Controlling Party will be entitled to join the Third Party Action and be represented by independent counsel of its own choice at its own expense.

(d) Appeal. In the event that a judgment in a Third Party Action is entered against either Party and an appeal is available, the Controlling Party shall have the first right, but not the obligation, to file such appeal. In the event the Controlling Party does not desire to file such an appeal, it will promptly, in a reasonable time period (i.e., with sufficient time for the non-Controlling Party to take whatever action may be necessary) before the date on which such right to appeal will lapse or otherwise diminish, permit the non-Controlling Party to pursue such appeal at such non-Controlling Party’s own cost and expense. If applicable Law requires the other Party’s involvement in an appeal, the other Party shall be a nominal party in the appeal and shall provide reasonable cooperation to such Party at such Party’s expense.

(e) Costs of an Action. Subject to the respective indemnity obligations of the Parties set forth in Article IX, the Controlling Party shall pay all costs and expenses associated with such Third Party Action other than the expenses of the other Party if the other Party elects to join such Third Party Action (as provided in the last sentence of Section 6.6(c)).

(f) No Settlement without Consent. Neither Licensor or TGTX shall settle or otherwise compromise (or resolve by consent to the entry of judgment upon) any Third Party Action by admitting that any Licensor Patent is to any extent invalid or unenforceable or that any Licensed Product, or its use, Development, importation, manufacture or sale infringes such Third Party’s intellectual property rights, in each case without the other Party’s prior written consent, and, in the case of Licensor, Licensor may not settle or otherwise compromise (or resolve by consent to the entry of judgment upon) a Third Party Action in a way that adversely affects or would be reasonably expected to adversely affect TGTX’s rights and benefits hereunder with respect to any Licensor Technology or any Licensed Product, without TGTX’s prior written consent.

ARTICLE VII.

CONFIDENTIALITY

7.1. Definitions. The Parties recognize that disclosures of Confidential Information between them before the Effective Date were subject to the Confidential Disclosure Agreement between them dated February 22, 2016. TGTX and Licensor each recognizes that during the Term, it may be necessary for a Party (the “Disclosing Party”) to provide Confidential Information (as defined herein) to another Party (the “Receiving Party”) that is highly valuable, the disclosure of which would be highly prejudicial to such Party. The disclosure and use of Confidential Information shall be governed by the provisions of this Article VII. Neither TGTX nor Licensor shall use the other’s Confidential Information except as expressly permitted in this Agreement. For purposes of this Agreement, “Confidential Information” means all information (including information relating to the business, operations and products of a Party or any of its Affiliates) disclosed by the Disclosing Party to the Receiving Party and which reasonably ought to have been understood to be confidential and/or non-public information at the time disclosed to the Receiving Party, or which is designated in writing by the Disclosing Party as “Confidential” (or equivalent), or which when disclosed orally to the Receiving Party is declared to be confidential by the Disclosing Party and is so confirmed in a writing delivered to the Receiving Party within * ( * ) days after such oral disclosure, including but not limited to any technical information, Know-How, trade secrets, or inventions (whether patentable or not), that such Party discloses to another Party under this Agreement, or otherwise becomes known to another Party by virtue of or that relates to this Agreement.

7.2. Obligation. Licensor and TGTX agree that they will disclose the other Party’s Confidential Information to its own (or its respective Affiliate’s, or with respect to TGTX, its Sublicensees’) officers, employees, consultants and agents only if and to the extent necessary to carry out their respective responsibilities under this Agreement or in accordance with the exercise of their rights under this Agreement, and such disclosure shall be limited to the maximum extent possible consistent with such responsibilities and rights. Except as set forth in the foregoing sentence, no Party shall disclose Confidential Information of the other to any Third Party without the other’s prior written consent. In all events, however, any and all disclosure to a Third Party (or to any such Affiliate or Sublicensee) shall be pursuant to the terms of a non-disclosure/nonuse agreement no less restrictive than this Article VII. The Party which disclosed Confidential Information of the other to any Third Party (or to any such Affiliate or Sublicensee) shall be responsible and liable for any disclosure or use by such Third Party, Affiliate or Sublicensee (or its disclosees) which would have violated this Agreement if committed by the Party itself. No Party shall use Confidential Information of the other except as expressly allowed by and for the purposes of this Agreement. Each Party shall take such action to preserve the confidentiality of each other’s Confidential Information as it would customarily take to preserve the confidentiality of its own Confidential Information (but in no event less than a reasonable standard of care). Upon expiration or termination of this Agreement, each Party, upon the other’s request, shall return or destroy (at Disclosing Party’s discretion) all the Confidential Information disclosed to the other Party pursuant to this Agreement, including all copies and extracts of documents, within * ( * ) days after the request, except for one archival copy (and such electronic copies that exist as part of the Party’s computer systems, network storage systems and electronic backup systems) of such materials solely to be able to monitor its obligations that survive under this Agreement.

7.3. Exceptions. The non-use and non-disclosure obligations set forth in this Article VII shall not apply to any Confidential Information, or portion thereof, that the Receiving Party can demonstrate by competent evidence:

(a) at the time of disclosure is in the public domain;

(b) after disclosure, becomes part of the public domain, by publication or otherwise, through no fault of the Receiving Party or its disclosees;

(c) is made available to the Receiving Party by an independent Third Party without obligation of confidentiality;provided, however, that to the Receiving Party’s knowledge, such information was not obtained by said Third Party, directly or indirectly, from the Disclosing Party hereunder; or

In addition, the Receiving Party may disclose information that is required to be disclosed by law, by a valid order of a court or by order or regulation of a governmental agency including but not limited to, regulations of the SEC or in the course of arbitration or litigation; provided, however, that in all cases the Receiving Party shall give the other party prompt notice of the pending disclosure and make a reasonable effort to obtain, or to assist the Disclosing Party in obtaining, a protective order or confidential-treatment order preventing or limiting (to the greatest possible extent and for the longest possible period) the disclosure and/or requiring that the Confidential Information so disclosed be used only for the purposes for which the law or regulation required, or for which the order was issued.

7.4. Third Party Information. The Parties acknowledge that the defined term “Confidential Information” shall include not only a Disclosing Party’s own Confidential Information but also Confidential Information of a Third Party which is in the possession of a Disclosing Party. TGTX and Licensor agree not to disclose to the other any Confidential Information of a Third Party which is in the possession of such Party, unless the other has given an express prior written consent (which specifies the owner of such Confidential Information) to receive such particular Confidential Information.

7.5. Press Releases and Disclosure. The Parties acknowledge that each Party may desire or be required to issue a press release or to make other public disclosures relating to the execution of this Agreement and its terms. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of such a press release or other public disclosure prior to the issuance thereof, provided that a Party may not unreasonably withhold consent to such release, and that either Party may issue such press release as it determines, based on advice of counsel, are reasonably necessary to comply with laws or regulations. (Provided, that no Party shall use the trademark or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or public disclosure relating to this Agreement or its subject matter, except as may be required by Law or required by the rules of an applicable * or * national securities exchange or except with the prior express written permission of such other Party, such permission not to be unreasonably withheld.) Notwithstanding the above, once a public disclosure has been made, either Party shall be free to disclose to third parties any information contained in said public disclosure, without further pre-review.

9.1. Indemnification by TGTX. TGTX shall indemnify, defend and hold Licensor and its Affiliates, and each of their respective employees, officers, directors and agents (the “Licensor Indemnitees”) harmless from and against any and all actions, judgments, settlements, liabilities, damages, penalties, fines, losses, costs and expenses (including reasonable attorneys’ fees and expenses) to the extent arising out of any Third Party claim, demand, action or other proceeding (each, a “Claim”) related to (a) TGTX’s performance of its obligations or exercise (by it or its Affiliates or Sublicensees) of its rights under this Agreement, including without limitation, product liability claims; or (b) breach by TGTX of its representations and warranties set forth in Article VIII; provided, however, that TGTX’s obligations pursuant to this Section 9.1 shall not apply (x) to the extent such claims or suits result from the gross negligence or willful misconduct of any of the Licensor Indemnitees, or (y) with respect to claims or suits arising out of breach by Licensor of this Agreement, including without limitation of its or their representations and warranties set forth in Article VIII.

9.4. 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.)

(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.

It is understood and agreed that this insurance shall not be construed to limit TGTX’s liability with respect to its indemnification obligations hereunder. TGTX shall upon request provide to Licensor upon request a certificate evidencing the insurance TGTX is required to obtain and keep in force under this Section 9.7.

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” shall mean the period from the Effective Date until the earlier of termination of this Agreement as provided in this Article X or expiration of this Agreement upon the expiration of the last-to-expire Royalty Term.) The Parties confirm that subject to the foregoing sentence, this Agreement shall not be terminated or invalidated by any future determination that any or all of the Licensor Patents have expired or been invalidated.

10.2. Termination upon Material Breach. If a Party breaches any of its material obligations under this Agreement, the Party not in default may give to the breaching Party a written notice specifying the nature of the default, requiring it to cure such breach, and, if desired, stating its intention to terminate this Agreement if such breach is not cured. If such breach is not capable of being cured, or is capable of being cured but nonetheless has not within * ( * ) days after the receipt of such notice been cured, then the Party not in default shall (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. In case of a breach of an obligation to pay money, which obligation to pay is not disputed in good faith, the cure period shall be * ( * ) days instead of * ( * ) days. The Parties agree that any failure by TGTX to pay when due * percent (* %) of such portion of any amount of money owing from TGTX to Licensor as is not disputed in good faith by TGTX (subject to the * ( * ) day cure period) shall conclusively be deemed to constitute a “material” breach. Notwithstanding the foregoing provisions, in the event of a good-faith dispute as to whether any alleged breach is in fact a breach, termination under this Section 10.2 in respect of such alleged breach shall not take effect unless and until (y) such dispute is resolved (according to the procedure described in 11.2) in favor of the Party alleging the breach or (z) the breaching Party’s denial that the alleged breach is in fact a breach ceases to be in good faith.

10.3. Termination for Bankruptcy. Licensor may terminate this Agreement immediately upon written notice to TGTX in the event that TGTX has a petition in bankruptcy filed against it that is not dismissed within * ( * ) days of such filing, files a petition in bankruptcy, or makes an assignment for the benefit of creditors. If TGTX has before such filing or such assignment entered into a written Sublicense which complies with Section 2.2, then the Sublicensee thereunder shall have the right to, by but only by delivering to Licensor within * ( * ) days after such termination a written election to do so and a written assumption of all of TGTX’s past and future obligations, liabilities and duties under this Agreement, convert its Sublicense into a direct of license from Licensor of the same technology, for the same field and for the same territory, as had been provided for in the Sublicense and otherwise on the same terms and conditions as are set forth in this Agreement as if such Sublicensee were TGTX hereunder. TGTX may terminate this Agreement immediately upon written notice to Licensor in the event that Licensor has a petition in bankruptcy filed against it that is not dismissed within * ( * ) days of such filing, files a petition in bankruptcy, or makes an assignment for the benefit of creditors.

10.4. TGTX Termination. TGTX may terminate this Agreement at any time for any reason upon * ( * ) days’ prior written notice to Licensor, provided that (i) TGTX and Hengrui attempted to resolve any issues in good faith, and (ii) TGTX and Hengrui agree to consult with each other with regard to public communications related to the termination of agreement. If TGTX has the right to terminate this Agreement pursuant to Section 10.2 for an uncured material breach by the Licensor, TGTX shall, within * ( * ) days after the end of the applicable cure period, elect in writing to either (i) exercise such right of termination with the effects set forth in Section 10.5 or (ii) waive such right of termination and any other right to pursue damages or other remedies in connection with such uncured material breach and maintain this Agreement in full force and effect provided that the then applicable royalty rates specified in Section 5.4, after taking into account all clauses thereunder, shall be and remain reduced by a further * % for the remainder of the term of this Agreement despite the * percent (* %) floor set by clause (f) in Section 5.4.

10.5. Effects of Termination/Expiration.

(a) Articles I (Definitions), VII (Confidentiality), IX (Indemnification; Limitation of Liability; Insurance) and XI (Miscellaneous Provisions) and Sections 5.6 (Royalty Reports and Records Retention), 5.7 (Audits), 5.9 (Late Payments), 5.10 (Taxes) and 10.5 (Effects of Termination/Expiration) hereof shall survive the expiration or termination of this Agreement for any reason.

(b) 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.

(c) Upon termination of this Agreement pursuant to Section 10.2 for an uncured material breach by TGTX or pursuant to Section 10.3, all licenses granted to TGTX hereunder shall terminate. If TGTX has before termination entered into a written Sublicense which complies with Section 2.2, then, if the Sublicensee thereunder is not then in breach of such Sublicense, the Sublicensee shall have the right to convert its Sublicense into a direct license from Licensor of the same technology, for the same field and for the same territory, as had been provided for in the Sublicense and otherwise on the same terms and conditions as are set forth in this Agreement as if such Sublicensee were TGTX hereunder. Such right of conversion shall be exercisable by Sublicensee by delivering to Licensor within * ( * ) days after such termination a written election to so convert. In addition, upon any termination of this Agreement pursuant to Section 10.2 for an uncured material breach by TGTX or pursuant to Section 10.3, TGTX and Licensor agree that TGTX shall: (i) assign to Licensor all Regulatory Approvals, applications for Regulatory Approvals and all drug master files and drug dossiers in the Territory, (ii) transfer to Licensor all correspondence and files pertaining to such Regulatory Approvals, applications for Regulatory Approvals and all drug master files and drug dossiers in the Territory, (iii) transfer to Licensor all data generated by TGTX, its Affiliates and Sublicensees in connection with the Development of the Licensed Products (in written or electronic form as Licensor may direct), (iv) grant, and hereby does grant, to Licensor a non-exclusive, fully-paid, perpetual, irrevocable license, with the right to sublicense through multiple tiers, to all intellectual property developed by TGTX, its Affiliates and Sublicenses in connection with the Development of the Licensed Products, and (v) upon the request of Licensor, assign to Licensor any contracts related to the Development, manufacture or Commercialization of the Licensed Products in the Territory under the following scenarios and conditions: (i) if at the time of termination TGTX has met the diligence milestone set forth under Section 3.1(a), the Licensor shall pay TGTX a royalty amounting to * % of Net Sales in the Territory on an annual basis until TGTX recovers * % of the cost of development of the Licensed Products; (ii) if at the time of termination TGTX has met the diligence milestone set forth under Section 3.1(b), the Licensor shall pay TGTX a royalty amounting to * % of * in the Territory on an annual basis until TGTX recovers * % of the cost of development of the Licensed Products; or (iii) if at the time of termination TGTX has dosed at least * in a Phase 3 clinical study or Pivotal Trial, the Licensor shall pay TGTX a royalty amounting to * % of Net Sales in the Territory on an annual basis until TGTX recovers * % of the cost of development of the Licensed Products. The cost of development of the Licensed Products shall include all costs and expenses incurred by TGTX as of the time of termination, as calculated in good faith by TGTX, subject to Licensor’s right to an audit. Net Sales shall have the meaning set forth under Section 1.31, except it shall apply to sales of the License Products by Licensor, its Affiliates, or any sublicensees. Licensor can, in its sole discretion, choose not to assume Regulatory Approvals and filings, data, or intellectual property generated by TGTX. In such event, TGTX will not be entitled to any cost of development recovery.

11.2. Disputes.

(a) The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 11.2 to resolve any controversy or claim arising out of, relating to or in connection with any provision of this Agreement, if and when a dispute arises under this Agreement. With respect to all disputes arising between the Parties, including, without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, if the Parties are unable to resolve such dispute within * ( * ) days after such dispute is first identified by either Party in writing to the other, the Parties shall refer such dispute to the Chief Executive Officers and/or Chairman for each Party for attempted resolution by good faith negotiations within * ( * ) days after such notice is received. If the senior executive officers designated by the Parties are not able to resolve such dispute within such * ( * ) day period, either Party may submit such dispute in accordance with Section 11.2(b).

(b) Arbitration.

(c) Notwithstanding anything to the contrary in this Article 11, either Party may seek injunctive relief in any court in any jurisdiction where appropriate.

11.3. Assignment.

(a) Any assignment not in accordance with this Section 11.2 shall be void.

(b) No assignment shall relieve the assigning Party of any of its responsibilities or obligations hereunder.

(c) Neither Party may transfer or assign its rights or licenses or delegate its obligations under this Agreement, in whole or in part, by operation of law or otherwise, to any Third Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed;provided that, notwithstanding the foregoing, either Party may assign its rights or licenses and/or delegate its obligations under this Agreement to an Affiliate or to a successor to all or substantially all of its assets, whether by way of merger, sale of all or substantially all of its assets, sale of stock or otherwise, without the other Party’s prior written consent. As a condition to any permitted assignment hereunder, the assignee must expressly assume, in a writing delivered to the other Party (and in a form reasonably acceptable to the other Party) all of such assigning Party’s obligations under this Agreement, whether arising before, at or after the assignment.

11.4. 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.

11.5. Force Majeure. 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. 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.

11.9. 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.

11.10. 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.

11.11. 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.

11.12. Third Party Beneficiaries. Except for the rights of Indemnified Parties pursuant to Article IX hereof and the rights of Sublicensees set forth in Sections 10.2 and 10.4(c), 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. The enforcement of any obligation of Licensor under this Agreement shall only be pursued by TGTX or such Indemnified Party, and not Sublicensees (except as set forth in Sections 10.2 and 10.4(c)).

11.13. No Implied License. No right or license is granted to TGTX hereunder by implication, estoppel, or otherwise to any know-how, patent or other intellectual property right owned or controlled by Licensor or its Affiliates, except by an express license granted hereunder. No right or license is granted to Licensor hereunder by implication, estoppel, or otherwise to any know-how, patent or other intellectual property right owned or controlled by TGTX or its Affiliates, except by an express license granted hereunder.

11.14. No Right of Set-Off. Except as expressly provided in Section 5.7(b) of this Agreement, TGTX shall not have a right to set-off any royalties, milestones or other amount due to Licensor under this Agreement against any damages incurred by TGTX for a breach by Licensor of this Agreement.

11.15. 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 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.

11.16. 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.

11.17. Use of Name. Neither Party shall be permitted to use the name, or any proprietary trademarks, trade names, trade dress or logos (“Marks”) of the other Party, or its Affiliates, or its Sublicensees, in any publicity, promotion, news release or public disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party. 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 facsimile or a portable document format (.pdf) copy of this Agreement, including the signature pages, will be deemed an original.
