4.2.1 During the term of the agreement, at least ninety (90) days prior to Array entering into [ * ] to grant to a Third Party the right to develop and/or commercialize that certain [ * ], Array agrees to notify ASLAN in writing, together with a summary description of the [ * ] (including a general statement of its then-current stage of development) and the scope of rights or field to be proposed, if any, that [ * ] (“Initial Notice”). Within thirty (30) days following receipt of such Initial Notice, ASLAN shall notify Array of its decision whether or not it desires to discuss terms and conditions under which Array will grant such rights to ASLAN. As soon as practicable following such notice the Parties shall enter into exclusive good faith negotiations to finalize the terms and conditions of such grant of rights. If (i) ASLAN notifies Array that it does not desire to

- 11 -

discuss such terms and conditions, or (ii) the parties have not agreed upon such terms and conditions pursuant to which such rights and license will be granted to ASLAN within ninety (90) days after the date Array provided the Initial Notice to ASLAN (the “Negotiation Period”), then Array shall be free to grant to any third party the right to develop and/or commercialize [ * ], without further obligation to ASLAN, and on any terms that Array deems appropriate. It is understood that, because Array will be providing the Initial Notice to ASLAN prior to [ * ] with a third party, Array may not be able to define the entire or exact scope of the product, field or rights to be granted, and accordingly, so long as the Initial Notice describes a product, field or rights that overlap with the product, field or rights discussed with, or granted to, a third party, Array shall be deemed to have satisfied its obligations; also, it is understood that Array need only provide one such Initial Notice hereunder before engaging in such material and substantial negotiations with the first third party, and that Array is not obligated to provide any further notice if Array subsequently engages in discussion with more than one third party with respect to the subject matter described in the Initial Notice. Such right is personal to ASLAN and will terminate upon the acquisition or merger of ASLAN.

4.2.2 No Implied Obligations. The only obligations of Array and ASLAN under Section 4.2.1 above are as expressly stated therein, and there are no further implied obligations relating to the matters contemplated therein, other than as are non-excludable by law. Without limiting the foregoing, it is further understood and agreed that [ * ] may or may not be advanced to any particular degree or at all at the time of the Initial Notice under Section 4.2.1, and that [ * ] may be conducted after the date of such Initial Notice; accordingly, so long as Array includes within the Initial Notice a good faith summary of [ * ] as it then exists, or a summary of the field in which the rights would be granted, the requirements of Section 4.2.1 above shall be deemed satisfied with respect to any and all activities after the date of the Initial Notice. Without limiting the foregoing, it is further acknowledged and agreed (i) that: this Section 4.2 shall not be deemed to apply to a transaction by which a Third Party acquires all or substantially all of the business assets of Array; and (ii) if Array enters into a transaction with a Third Party in accordance with this Section 4.2 that includes [ * ] (each such [ * ] being referred to as a “ [ * ]”), then the grant of rights by Array upon a Third Party’s exercise of such Contingent Right shall not be subject to this Section 4.2 so long as the grant of such [ * ] was made in a transaction entered into with the Third Party in compliance with Section 4.2.1; and (iii) Array is not obligated under this Section 4.2 to provide ASLAN any particular information other that as expressly stated in Section 4.2.1, and that Array may require a separate confidentiality agreement as a condition to any disclosure of information in connection with Section 4.2.

4.2.3 Disputes. If ASLAN disputes Array’s right to proceed to enter into any transaction with a Third Party with respect to [ * ], ASLAN shall submit such dispute for determination by a neutral expert (“Expert”) within ten (10) days from the end of the Negotiation Period, and such issue shall be finally resolved by the Expert pursuant to this Section 4.2.3 (“Expert Determination”). ASLAN shall provide Array a notice of such Expert Determination together with a written report setting forth the specific basis for the dispute and the specific actions ASLAN

- 12 -

believes Array must take to resolve the dispute (“Dispute Resolution Notice”). If a Dispute Resolution Notice is not received within the ten (10) day period then ASLAN shall have no further right to dispute Array’s right to grant any Third Party rights contemplated by this Section 4.2. In the event of such Expert Determination, the Expert shall be an independent expert in the biotechnology industry with relevant experience, mutually acceptable to the Parties. If the Parties are unable to agree on an Expert, the Expert shall be an independent expert as described in the preceding sentence, selected by the chief executive of the UK Bio-Industry Association (“BIA”). Any such Expert Determination shall be held in London, UK, and shall be conducted in English. Each Party shall prepare a written report setting forth its position with respect to whether Array has the right to proceed to enter into any transaction with a Third Party, and supporting documents or affidavits as such Party deems appropriate. The Expert shall not order or require discovery against either party. The Expert shall select one of the Party’s positions as his decision, and shall not have authority to render any substantive decision other than to so select the position of either ASLAN or Array. The costs of such Expert Determination shall be shared equally by the Parties, and each Party shall bear its own expenses in connection with such Expert Determination. It is the desire and objective of the Parties that the dispute is settled by Expert Determination within 30 days of Dispute Resolution Notice, or in any event as soon thereafter as is practicable.

ARTICLE VI - DILIGENCE

It is important to Array and ASLAN that Product development and licensing proceed expeditiously. Accordingly, ASLAN shall use Diligent Efforts to conduct the Development Program and the Licensing Program under Sections 3.1 and 7.1 of this Agreement, and to obtain the optimum commercial return for Products in all markets throughout the world. ASLAN shall develop and license all Products in the best interests of maximizing the success of such Products, and not in the present or future interest of other products of ASLAN (other than Products).

ARTICLE VII - LICENSING PROGRAM; BUY-OUT

7.1 Licensing Program. Subject to the terms and conditions of this Agreement, Array hereby grants ASLAN an exclusive license under applicable Array Technology to pursue the Licensing Program and to sub-license or license (as applicable) to Third Parties the further development and commercialization of the Licensed Technology and/or the Products in the Territory in accordance with the provisions of this Article VII and under license terms and conditions mutually acceptable to the Parties and/or following the procedures under Section 2.2.3.

7.1.1 ASLAN will use Diligent Efforts to negotiate term sheets and execute agreements with potential licensees, keeping Array informed as to material terms of such negotiations. For each potential licensee of the Licensed Technology, the parties via the JSC shall seek to agree on an appropriate field. Array will reasonably cooperate to assist ASLAN in its efforts to pursue the Licensing Program by making available, at no extra charge to ASLAN, such additional or complementary data or information related to Products that is Controlled by Array as may be appropriate and reasonably required to progress licensing discussions with Third Parties in connection with the Licensing Program.Unless approved by both Parties, neither Party shall, during the term of this Agreement, have the right to separately grant a license with respect to Products to any Third Party under its Licensed Technology.

7.1.2 Approximately 6 months prior to the anticipated Completion of the Development Program or earlier if available data permits, ASLAN will begin business development activities in connection with the Licensing Program. ASLAN agrees not to enter into any license agreement pursuant to the Licensing Program until such time as ASLAN has provided a complete copy of the final license draft to Array, and either: (i) each of the Parties have approved the license agreement, if such license is entered into prior to Completion of the Development Program, or (ii) each of the Parties have approved the license agreement, or the procedures under Section 2.2.3 have been exhausted, if such license is entered into after Completion of the Development Program. In exercising any right to give or withhold approval in relation to the terms of a proposed license of the Licensed Technology or any other part of this Agreement, Array shall act in a timely and reasonable manner and use Diligent Efforts. For purposes of clarity: (x) prior to Completion of the Development Program ASLAN may not enter into any license under the Licensing Program without Array’s prior written consent; (y) after Completion of the Development Program, ASLAN, subject to

- 14 -

Section 2.2.3 and all dispute resolution provisions in this Agreement, may conclude a license under the Licensing Program without Array’s written consent.

In the event of such [ * ], the [ * ] shall be [ * ], mutually acceptable to the Parties, who has [ * ]. If the Parties are unable to agree on a [ * ], the [ * ] shall be an [ * ] as described in the preceding sentence, selected by the chief executive of the UK Bio-Industry Association (“BIA”). Any such [ * ] shall be held in London, UK, and shall be conducted in English. Each Party shall prepare a written report setting forth its position with respect to whether [ * ] that are [ * ] (as defined herein) are [ * ], and supporting documents or affidavits as such Party deems appropriate.

(c) If the Offeree does not provide an Offeree’s Buy-Out Notice within forty-five (45) days after receiving the Offeror’s Buy-Out Notice, the Offeree shall be deemed to have accepted the Offeror’s buy-out offer in the Offeror’s Buy-Out Notice. The Offeree may, in its discretion, also accept the Offeror’s buy-out offer by written notice to the Offeror before expiration of such forty-five (45) day period;

(d) If the Offeree accepts, or is deemed to have accepted, the Offeror’s buy-out offer in the Offeror’s Buy-Out Notice, then (i) the Offeror shall pay the Offeree the Buy-Out Price within twenty (20) days and shall thereafter have the exclusive right to grant licenses to Third Parties under the Licensed Technology to develop and/or commercialize Products for pharmaceutical uses (and, for the avoidance of doubt, shall not be obligated to share Net Licensing Revenues from such licenses with the Offeree), and (ii) ASLAN and Array shall promptly prepare and enter into a definitive written agreement memorializing appropriate exclusive licenses to the Offeror under the Offeree’s interest in the Licensed Technology; and

(e) If the Offeree provides an Offeree’s Buy-Out Notice within the forty-five (45) day period described in Section 7.3(b), then (i) the Offeree shall pay to the Offeror the Buy-Out Price within twenty (20) days and shall thereafter have the exclusive right to grant licenses to Third Parties under the Licensed Technology to develop and/or commercialize Products for pharmaceutical uses (and, for the avoidance of doubt, shall not be obligated to share Net Licensing

In the event of such an extension, ASLAN agrees to promptly notify Array in writing of any conclusion of such negotiations with such third party.

11.2 Term Where License(s) Have Been Entered Into. If, before the end of the period (or any agreed adjustment) referred to in Section 11.1, ASLAN has entered into a license(s) with a Third Party under the Licensing Program, then (i) the license to ASLAN under Section 7.1 of this Agreement, and the rights of ASLAN under this Agreement to grant a license or sublicense under other Licensed Technology pursuant to the Licensing Program, shall continue in full force and effect, solely to the extent necessary to permit the continued granting by ASLAN of the license or sublicense under the Licensed Technology to the applicable Third Party under such license(s), for so long as such license(s) granted by ASLAN remain in full force and effect, (ii) this Agreement shall in all other respects terminate, and (iii) in so far as applicable the remainder of this Section 11 (in so far as relevant) shall apply.

- 25 -

11.3 Termination For Breach. Either Party may terminate this Agreement in the event the other Party shall have materially breached or defaulted in the performance of any of its material obligations hereunder, and such default shall have continued for ninety (90) days after written notice thereof was provided to the breaching Party by the non-breaching Party. Any termination shall become effective at the end of such ninety (90) day period unless the breaching Party (or any other party on its behalf) has cured any such breach or default prior to the expiration of the ninety (90) day period.

11.4 Termination Upon Notice.

11.4.1 Either Party Notice. Either Party may terminate the Agreement at any time in the event that (i) pre-agreed stopping criteria set forth in the Development Plan are met, or (ii) in the event of a material safety risk associated with the Product.

11.4.2 Array Notice.

(a) Failure to Initiate Committed Trial Within One Year of Effective Date. In the event ASLAN does not initiate any of the Committed Trials within one year of the Effective Date, then, subject to Array having fully complied with all its obligations to ASLAN under this Agreement in respect of such Committed Trial(s), then Array may, in its discretion, terminate this Agreement, upon sixty (60) days written notice to ASLAN and the remainder of this Section 11 shall apply; provided that such termination shall be ineffective if ASLAN both (i) initiates the Committed Trial(s) on or before the date sixty (60) days after such notice from Array (or on or before such later date as the Parties may mutually agree in writing); and (ii) certifies such initiation of the Committed Trial in writing to Array prior to the expiration of such sixty (60) day period (or on or before such later date as the Parties may have mutually agreed in writing).

(b) Notification of Missed Timeline. In the event ASLAN does not initiate and complete (i.e., conduct through to Completion) any of the Committed Trials within the timeframe set forth for such Committed Trial as set forth in the applicable Development Plan, ASLAN shall notify Array, through Array’s representatives on the JDC, and on request of Array the Parties will discuss the matter and its potential effects on timing of the overall Development Program.

(c) Request for Extension. In the event that ASLAN believes that, despite using active and Diligent Efforts, it will not be able to complete the Development Program as a whole within the applicable timeframe set forth in the applicable Development Plan for reasons beyond its control, it may request that the JSC consider a potential extension of the timeframe to complete the Development Program, and the procedures in Section 2.2.3 shall apply. It is understood and agreed, however, that Array via the JSC may refuse to agree to any such extension for completion of the overall Development Program, if ASLAN has failed to use at all times active and Diligent Efforts of at least the level required by Article VII, or if Array believes in good faith

- 26 -

and on reasonable objective grounds that Completion of the Development Program would nonetheless have been achievable within the applicable timeframe, notwithstanding those reasons claimed to be beyond ASLAN’s control.

(d) Termination Upon Notice from Array. If ASLAN does not complete the Development Program within the timeframe set forth in the applicable Development Plan, taking into account any extensions thereof approved by the JSC (within the scope of its authority) or agreed to in writing by Array, then Array may, in its discretion, terminate this Agreement, upon one hundred and eighty (180) days written notice to ASLAN, provided that such termination shall be ineffective if ASLAN both (i) conducts all of the applicable Committed Trial(s) through to Completion on or before the date one hundred and eighty (180) days after such notice from Array (or on or before such later date as the Parties may mutually agree in writing); and (ii) certifies such Completion in writing to Array prior to the expiration of such one hundred and eighty (180) day period (or on or before such later date as the Parties may have mutually agreed in writing).

11.5 Termination on Insolvency. Either Party may terminate this Agreement by notice, if, at any time, the other Party (i) suspends payment of its debts or is unable to pay its debts as they fall due or admits inability to pay its debts or is deemed unable to pay its debts within the meaning of section 123 of the Insolvency Xxx 0000; or (ii) a petition is filed, a notice is given, a resolution is passed, or an order is made, for or in connection with the winding up of that Party (other than for the sole purpose of a scheme for a solvent amalgamation of that Party with one or more other companies or the solvent reorganisation of that Party); or (iii) an application is made to court, or an order is made, for the appointment of an administrator, or if an administrator is appointed over that Party; or (iv) a receiver is appointed over all or any of the assets of that Party; or (v) a creditor or encumbrancer of that Party attaches or takes possession of, or a distress, execution, sequestration or other such process is levied or enforced on or sued against, the whole or any part of the assets of that Party and such attachment or process is not discharged within thirty (30) days; or (vi) any event occurs, or proceeding is taken, with respect to that Party in any jurisdiction to which it is subject that has an effect equivalent or similar to any of the events mentioned in this Section 11.5 (i) to (v); or (vii) that Party suspends or ceases, or threatens to suspend or cease, to carry on all or a substantial part of its business.

11.6 Effect of Termination.

11.6.1 Accrued Rights, Surviving Obligations. Termination, relinquishment or expiration of the Agreement for any reason shall be without prejudice to any obligations which shall have accrued prior to such termination, relinquishment or expiration, including, without limitation, any and all damages arising from any breach hereunder.

11.6.2 Survival. Articles I, X and XII and Sections 3.5(a), 7.1.4, 8.1.1, 9.1, 9.2, 11.6, 11.7 and 11.8 shall survive the expiration and any termination of this Agreement; and Article V shall survive the expiration but not an earlier termination (except as provided below) of this

- 27 -

Agreement. Except as provided in this Section 11.6.2, or as otherwise provided in this Section 11.6, all obligations of each Party under this Agreement shall terminate upon any termination of this Agreement in its entirety.

11.7 Effect of Certain Terminations. In the event of expiration (i.e., without a successful conclusion of the Licensing Program) or early termination of this Agreement pursuant to Section 11.4.2 or a termination of this Agreement under Section 11.3 by reason of breach by ASLAN, the following shall apply:

11.7.1 Array shall have (and ASLAN agrees to grant and hereby grants to Array) an irrevocable, exclusive, royalty-free worldwide license, with the right to grant and authorize sublicenses, under all Licensed Technology Controlled by ASLAN, and under any trademarks owned by ASLAN and used specifically by ASLAN to identify the Products (excluding the ASLAN trade name and trade dress), to make, use, sell, import and otherwise exploit all Products. The foregoing rights and license shall be fully paid and royalty-free, provided that, if Array subsequently commercializes Products or grants a third party a license to commercialize Products, then Array shall pay to ASLAN either (i) if Array commercializes Products itself, a royalty on the Net Sales of such Products worldwide at a rate of [ * ], or (ii) if Array grants a Third Party a License to commercialize Products [ * ] of the Net Licensing Proceeds received therefrom, in each case up to the amount equal to ASLAN’s actual costs expended by ASLAN in performing the Development Plan, plus [ * ] beginning on the date of first commercial sale of a Product by Array or an Array licensee. For the avoidance of doubt, no payments will be due under this Section 11.7.1 in the event that Array buys out ASLAN’s rights to license Third Parties to develop and commercialize Products as described in Section 7.3.

11.7.2 Development. In the event there are any ongoing clinical trials of any Product, at Array’s request, following the date a notice of termination has been issued by Array pursuant to Section 11.3 or 11.4.2, ASLAN agrees to continue such trials in the normal course until the effective date of the termination, or, to the extent so requested by Array, to promptly transition to Array or its designee such clinical trials or portions thereof; in each case, at ASLAN’s expense.

11.7.3 Other. ASLAN shall, at Array’s request, take all steps reasonably necessary to enable Array to develop and commercialize Products in the Territory, including transferring to Array any regulatory submissions for such Products, selling manufactured materials and Product inventory, in Development Data, reports, SOPs, protocols, ASLAN Know-How or other commercially reasonable arrangements as the Parties may agree.

11.8 Termination Not Sole Remedy. Termination is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies will remain available except as agreed to otherwise herein.

12.6 Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing.
