WHEREAS:-

(A) CSL is a pharmaceutical company that is engaged in the discovery, research, development and commercialization of compounds for treating disease in humans. CSL owns certain patent rights and technology relating to the Product.

(B) CSL desires to ensure that the clinical development of the Product through Clinical Proof of Concept is achieved as promptly as possible and thereafter that the commercial potential of the Product in the Territory and within the Field is realized promptly through ASLAN and/or a suitable partner or partners.

(C) ASLAN possesses pharmaceutical development capabilities, and desires to secure rights from CSL for the further development of the Product for the treatment of respiratory and inflammatory conditions and in particular atopic dermatitis as set forth in this Agreement and further desires to make the commitment and investment to conduct clinical development of the Product through Clinical Proof of Concept and to realize promptly the therapeutic and commercial potential of the Product either itself and/or through a suitable partner or partners.

(D) In the period which has elapsed since the original Effective Date, (i) ASLAN has expanded its capabilities so that it is now able to develop the Product beyond Clinical Proof of Concept and is planning to expand its capabilities to enable it to Commercialise the Product itself; and (ii) the gene expression system most suited for scaled-up production of the Product has been determined to be based on technology of Selexis S.A. and not of Lonza Sales AG as originally envisaged; accordingly the second amendment to this Agreement is being entered into to provide terms more appropriate to the foregoing.

Now, therefore, in consideration of the premises and mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

10.2 ASLAN must not set off any amounts owing to CSL under or in connection with this Agreement.

Royalty payments

10.3 ASLAN shall pay CSL quarterly, on a country-by-country, Product-by-Product basis until the end of the Term, royalties at the applicable rate set out below, depending on the relevant aggregate and cumulative amount(s) of Annual Net Sales of Product (based on the relevant calendar year) by ASLAN, its Affiliates and/or Sub-licensees (“CSL Royalties”):

Annual Net Sales amount	Royalty rate
From $0 up to US$[…***…]	[…***…]%

To the extent Net Sales exceed […***…] up to […***…]:	[…***…]%
To the extent Net Sales exceed […***…]:	[…***…]%

10.4 Within […***…] days of the end of each calendar quarter during which there are Net Sales, subject to section 10.5, ASLAN shall make the relevant payment of CSL Royalties and provide CSL with a Royalty Report specifying:

28 Deed of Amendment and Restatement

License Agreement

10.4.1 the nature of and amount of the payment received that contributes to Net Sales (including copies of any notifications, reports or statements from the Sub-licensees relating to the contribution);

10.4.4 details of the cumulative Annual Net Sales for the relevant year as at the date of the statement; and

10.4.5 a statement of the amount of payment due to CSL in respect of such CSL Royalties.

10.5 To the extent that Net Sales for the purposes of calculating CSL Royalties pursuant to Section 10.4 are generated in a calendar quarter by a Sub-licensee, and ASLAN has not received royalties or other payments due to it from such Sublicensee in respect of such Net Sales by […***…] from the end of the relevant calendar quarter, then ASLAN may defer payment of the portion of the CSL Royalties derived from the Net Sales by such Sub-licensee until the earlier of (a) the time ASLAN actually receives the royalties or other payments from the Sublicensee; or (b) […***…] from the end of the relevant calendar quarter.

10.6 ASLAN must remit payment to CSL to a bank account nominated by CSL.

10.7 Currency. Payments to CSL must be in USD.

10.8 CSL Royalties for the Convenience of the Parties. Given the worldwide scope of this Agreement and the impracticality of establishing the relative contribution of each element of Licensed Technology to the value of Product(s), in particular at the stage in the development cycle for Product(s) at which the Parties are entering into this Agreement, it is agreed and recognised that paying CSL Royalties on a worldwide basis at the rates and for the term set forth in this Agreement is fair and reasonable, representing a balance between the concerns and interests of both Parties and resulting in a convenience for ASLAN.

11.4 If CSL’s inspection reveals that any monies are outstanding then ASLAN must, within […***…] after receiving notice of the amount due, pay CSL the outstanding amount. If the inspection reveals there was an overpayment then the amount of the overpayment may be credited against future payments due to CSL under this Agreement.

11.5 CSL shall bear the cost of the independent accountant appointed under this Section 11 except if the inspection reveals that any monies are outstanding by more than […***…]%, in which case ASLAN must pay CSL’s reasonable inspection costs.

(i) to its Affiliates, directors, employees, permitted sub- licensees, consultants and advisors (and the directors, employees, consultants and advisors of its Affiliates) (Representatives) to the extent necessary for the Permitted Purpose provided that the Party must ensure that any such Representative complies with the obligations of confidence and non-use set out in this Agreement

(ii) the terms of this Agreement may be disclosed to its legal and financial advisors, who must be bound by similar obligations of confidentiality as contained in this Agreement;

(iii) ASLAN may disclose CSL’s Confidential Information to Third Parties for the purposes of Sub-licensing on a need to know basis, and who must be bound by similar obligations of confidentiality as contained in this Agreement, provided, however, that in relation to any confidentiality obligations which relate solely to information not subject to obligations of confidence under a CSL Third Party Technology Agreement, ASLAN may

37 Deed of Amendment and Restatement

License Agreement

agree for the duration of such obligations to be less than the duration specified in the first sentence of Section 15.3, provided further that such duration must in all cases be at least […***…] from the date of disclosure of the relevant information by ASLAN;

(iv) with CSL’s prior written consent (not to be unreasonably withheld), ASLAN may disclose CSL’s Confidential Information to potential investors, or acquirers, on a need to know basis, and who must be bound by similar obligations of confidentiality as contained in this Agreement;

15.4 Specific enforcement. Each Party acknowledges that:

15.4.1 the value of the other Party’s Confidential Information, which includes any jointly owned Confidential Information, is unique and difficult to assess in monetary terms;

15.4.2 a breach by it of any of its obligations of confidentiality under this Agreement may irreparably harm the Party disclosing such Confidential Information, and damages may not be an adequate remedy for any such breach; and

15.4.3 therefore, if it actually breaches or threatens to breach the confidentiality obligations set forth in this Agreement, the Party whose Confidential Information is the subject of such breach, or who is affected by such breach, may seek to enforce this Agreement by way of injunctive relief or specific performance as a remedy (in addition to any other available relief) without proof of actual or special damage.

Nothing in this Section shall permit ASLAN to disclose Confidential Information which is subject to obligations of confidentiality under the Third Party Technology Agreement, except with CSL’s written consent. CSL and ASLAN will, from time to time, and at the request of the other Party, discuss and agree on the general information content relating to this Agreement which may otherwise be publically disclosed.
