If [***] desires to include in any such listing any such [***] Patent Rights, then [***] shall notify [***] and shall consider in good faith [***] reasonable comments with respect thereto, provided that [***] shall [***] with respect to any such listing. If [***] reasonably believes that a Patent Right other than any [***] Patent Rights should be included in any such listing, [***] shall consider in good faith [***] request with respect thereto.

9.4.5 Enforcement of Listed Patents. The provisions of Sections 9.4.2 and 9.4.3 notwithstanding, the following shall apply with respect to any notification provided by a Third Party to either ALEXION or ZEALAND under 21 U.S.C. § 355(j)(2)(B) making a certification described in 21 U.S.C. §355(j)(2)(A)(vii)(IV) with respect to any Agreement Patent Rights listed in the Orange Book for a Product and with respect to equivalent actions in the United States or in any other country within the Territory (a “Paragraph IV Certification”):

(a) The Party receiving a Paragraph IV Certification shall, without any avoidable delay and in any case within [***] Business Days after receiving such a Paragraph IV Certification, notify the other Party in writing and shall attach a copy of the Paragraph IV Certification to such notification.

(b) The rights to initiate or continue any infringement proceeding as a result of the Paragraph IV Certification with respect to a Product, including the commencement of a patent infringement action under 35 U.S.C. § 271(e)(2)(A), or under an equivalent statute or regulation within any other country in the Territory (a “Paragraph IV Proceeding”) shall be governed by Section 9.4.2, and any [***] Patent Rights (or other Patent Rights listed pursuant to Section 9.4.4) subject to a Paragraph IV Proceeding shall be considered an Infringed Patent under the [***] Patent Rights for purposes of interpreting Section 9.4.2.

9.5 Defense of Claims. Each Party shall promptly inform the other in writing of any written notice to it of alleged infringement or misappropriation, based upon its performance of its obligations or exercise of its rights hereunder, of a Third Party’s Intellectual Property of which it shall become aware. Except as otherwise set forth herein (including under Article 11), each Party shall have the sole right to defend against any such claim brought against it, provided, however, that to the extent such action resulting from such claim involves an objection, opposition or challenge to any Agreement Patent Rights or ZEALAND Patent Rights by such Third Party or a counterclaim involving such Patent Rights, Section 9.4.2 or Section 9.4.3 shall apply, as applicable. Each Party shall each keep the other advised of all material developments in the conduct of any proceedings in defending any claim of such alleged infringement or misappropriation and shall reasonably cooperate with the other in the conduct of such defense. In no event may either Party settle any such infringement or misappropriation claim in a manner that would limit the rights of the other Party, admit the fault of the other Party or impose any obligation on the other Party, without such other Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

10.2 Press Release. The Parties shall issue a press release following the execution of this Agreement describing the nature of the collaboration between ALEXION and ZEALAND in the form set out in Schedule 10.

11. INDEMNIFICATION AND LIABILITY

11.1 Indemnification by ZEALAND. ZEALAND shall indemnify, defend, and hold harmless ALEXION and its Affiliates and their respective officers, directors, employees, licensees, sublicensees, and agents, and their respective successors, heirs and assigns and representatives (the “ALEXION Indemnitees”), from and against any and all damages, losses, suits, proceedings, liabilities, costs and expenses (including reasonable legal expenses, costs of litigation and reasonable attorney’s fees) or judgments, whether for money or equitable relief, of any kind (collectively, “Damages”) resulting from any and all suits, investigations, claims or demands of Third Parties (collectively, “Third Party Claims”) brought against an ALEXION Indemnitee, to the extent directly or indirectly arising out of or relating to: (i) the gross negligence or willful misconduct of ZEALAND, its Affiliates and its respective officers, directors, or employees in connection with ZEALAND’s performance of its obligations under this Agreement, (ii) any breach by ZEALAND of any obligation, representation, warranty or covenant set forth in this Agreement and (iii) the failure of ZEALAND or its Affiliates to comply with any Applicable Laws, in each case except to the extent ALEXION is liable for such Damages pursuant to Section 11.2.

11.2 Indemnification by ALEXION. ALEXION shall indemnify, defend, and hold harmless ZEALAND and its Affiliates, and its and their respective officers, directors, employees, and agents, and their respective successors, heirs and assigns and representatives (the “ZEALAND Indemnitees”), from and against any and all Damages resulting from Third Party Claims against a ZEALAND Indemnitee (including by ALEXION employees), to the extent directly or indirectly arising out of or relating to (i) the gross negligence or willful misconduct of ALEXION, its Affiliates, and its and their respective licensees, officers, directors, employees in connection with ALEXION’s performance of its obligations or exercise of its rights under this Agreement, (ii) any breach by ALEXION of any obligation, representation, warranty or covenant set forth in this Agreement, (iii) the failure to comply with any Applicable Laws by ALEXION, its Affiliates, or any of its licensees, or (iv) use, Development, Manufacture, Commercialization or other exploitation of any Candidate Product or Product by or on behalf of ALEXION or its Affiliates or Sublicensees, in each case except to the extent ZEALAND is liable for such Damages pursuant to Section 11.1.

11.3 Notification; Assumption of Defense; Cooperation and Assistance. In the event that a Party seeks indemnification hereunder with respect to a Third Party Claim, the Party seeking indemnification (the “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) in writing (an “Indemnification Claim Notice”) of any Third Party Claim in respect of which it intends to claim indemnification under this Section 11.3 upon actual knowledge of any such claim or proceeding resulting in Damages, but in no event will the Indemnifying Party be liable for any Damages that result from any delay in providing such notice. The Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Damages (to the extent that the nature and amount of such Damages is known at such time). The Indemnifying Party may, at its option, assume exclusive control of the defense and settlement of the Third Party Claim, subject to the limitations on settlement set forth below and in Section 9.5. If the Indemnifying Party assumes such defense, such assumption shall not be construed as an acknowledgement that the Indemnifying Party is liable to indemnify the Indemnified Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Following such assumption, the Indemnifying Party may appoint as lead counsel

in the defense of the Third Party Claim any legal counsel selected by the Indemnifying Party (the Indemnifying Party will consult with the Indemnified Party with respect to a possible conflict of interest of such counsel retained by the Indemnifying Party). The Indemnified Party will have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party. If the Indemnifying Party does not commence actions to assume control of the defense of a Third Party Claim within [***] days after the receipt by the Indemnifying Party of the Indemnification Claim Notice required pursuant to this Section 11.3, or if shorter, prior to the date which is [***] Business Days before the expiry of any deadline to respond to a claim, the Indemnified Party will have the right to defend such claim in such manner as it may deem appropriate at the reasonable cost and expense of the Indemnifying Party. The Indemnified Party shall cooperate as may be reasonably requested by the Indemnifying Party (and at the Indemnifying Party’s expense) in order to ensure the proper and adequate defense of any action, claim or liability covered by this indemnification. The Indemnifying Party may not settle or otherwise dispose of any Third Party Claim without the prior written consent of the Indemnified Party unless such settlement includes only the payment of monetary damages (which are fully paid by the Indemnifying Party), does not impose any injunctive or equitable relief upon the Indemnified Party, does not require any admission or acknowledgment of liability or fault of the Indemnified Party and contains an unconditional release of the Indemnified Party in respect of such Third Party Claim. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle or otherwise dispose of any Third Party Claim for which the Indemnifying Party may be liable for Damages under this Agreement without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, conditioned or delayed.

12. TERM AND TERMINATION

12.1 Term. This Agreement shall commence upon the Effective Date and, if not otherwise terminated earlier pursuant to this Article 12, shall continue in full force and effect on a Product-by-Product basis, until the expiration of the last payment obligation by ALEXION with respect to such Product (collectively, the “Term”).

12.2 Termination for Cause.

12.2.1 By ALEXION. In the event of a material breach of this Agreement by ZEALAND, which material breach remains uncured for [***] days measured from the date of written notice of such material breach by ALEXION as may be extended for the Mediation Period pursuant to Section 12.3, which notice identifies the material breach and the actions or conduct that it reasonably considers would be an acceptable cure of such material breach, ALEXION may terminate this Agreement in whole or with respect to one or more Candidate Products, Products or Targets, at any time during the Term of this Agreement by written notice of termination to ZEALAND.

12.2.2 By ZEALAND. In the event of a material breach of this Agreement by ALEXION, which material breach remains uncured for [***] days measured from the date of written notice of such material breach by ZEALAND as may be extended for the Mediation Period pursuant to Section 12.3, which notice identifies the material breach and the actions or conduct that it reasonably considers would be an acceptable cure of such material breach,

ZEALAND may terminate this Agreement in whole or with respect to one or more Candidate Products, Products or Targets to which such material breach relates, at any time during the Term of this Agreement by written notice of termination to ALEXION.

12.3 Disputes regarding Material Breach. In case the Party alleged to have committed the material breach (the “Defaulting Party”) disputes the material breach identified under Section 12.2.1 or 12.2.2 by the other Party (the “Non-Defaulting Party”), then the issue of whether the Non-Defaulting Party may properly terminate this Agreement on expiration of the Mediation Period in accordance with Section 13.8. This Agreement shall remain in full force and effect while any mediation pursuant to Section 13.8.2 is pending, such mediation shall not suspend any obligations of either Party hereunder, and each Party shall use reasonable efforts to mitigate any damage. If as a result of any dispute resolution proceeding (including litigation) it is determined that the Defaulting Party did not commit such material breach or such material breach was cured at any time during the Mediation Period in accordance with this Section 12.3, then no termination shall be effective, and this Agreement shall continue in full force and effect.

12.4 Termination for Insolvency. To the extent permitted by Applicable Laws, either Party may terminate this Agreement upon the filing or institution of bankruptcy, restructuring, reorganization, liquidation or receivership proceedings, upon the appointment of a receiver or trustee in respect of the other Party or over all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate shall only become effective if (i) the other Party consents to the involuntary bankruptcy, (ii) a bankruptcy decree is rendered or (iii) the bankruptcy filing is not dismissed within [***] days after the filing thereof (an “Insolvency Event”).

12.4.1 All rights and licenses now or hereafter granted by ZEALAND to ALEXION under or pursuant to this Agreement are, for all purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon an Insolvency Event, ZEALAND agrees that ALEXION, as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. ZEALAND will, during the Term, create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all intellectual property licensed under this Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property within the meaning of Section 365(n) include laboratory notebooks, cell lines, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, the Licensed IP and Collaboration IP and all information related to the Licensed IP and Collaboration IP. If (i) a case under the U.S. Bankruptcy Code is commenced by or against ZEALAND, (ii) this Agreement is rejected as provided in section 365 of the U.S. Bankruptcy Code and (iii) ALEXION elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, ZEALAND (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(a) provide ALEXION with embodiments of all Licensed IP and Collaboration IP held by ZEALAND and such successors and assigns,

or otherwise available to them, immediately upon ALEXION’s written request, and ALEXION will have the right to perform ZEALAND’s obligations hereunder and exercise all of the rights of a licensee of intellectual property under section 365(n) of the Bankruptcy Code, provided that neither such provision nor such performance by ALEXION will release ZEALAND from liability resulting from rejection of the license or the failure to perform such obligations; and

(b) not interfere with ALEXION’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code.

12.4.2 All rights, powers and remedies of ALEXION provided herein are in addition to and not in substitution for any other rights, powers and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy Code with respect to ZEALAND. The Parties intend the following rights to extend to the maximum extent permitted by Applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n):

(a) the right of access to any intellectual property rights (including all embodiments thereof) of ZEALAND, or any Third Party with whom ZEALAND contracts to perform an obligation of ZEALAND under this Agreement to the extent that ZEALAND is not performing such obligation, and, in the case of any such Third Party, which is necessary for the Manufacture, use, sale, offer for sale, import or export of Products; and

(b) the right to contract directly with any Third Party to complete the contracted work to the extent that ZEALAND is not completing or having completed the contracted work.

[***] acknowledges and agrees that a breach of its obligations under this Article 12 shall constitute a material breach of this Agreement, and any such breach would cause [***] irreparable harm and damage for which [***] would have no adequate remedy at law and for which monetary damages would be inadequate, and [***] further agrees

that in the event of a breach of such obligations [***] would be entitled to seek an injunction to compel [***] compliance with such obligations, in addition to any other remedies.

12.6 Termination at Will. ALEXION shall be entitled to terminate this Agreement, in whole or with respect to one or more Candidate Products, Products or Targets, at its sole discretion at any time upon [***] days prior written notice to ZEALAND.

13. CONCLUDING PROVISIONS

13.1 Assignment and Change of Control. Neither Party shall be entitled to assign or otherwise transfer its rights and/or obligations under this Agreement in whole or in part 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, each Party may

assign this Agreement to (i) any Affiliate, or (ii) any successor corporation or entity resulting from any Change of Control of such Party; and provided further, that any such successor Affiliate, entity or Third Party to which this Agreement is assigned expressly agrees in writing to assume and be bound by all obligations of the assigning Party under this Agreement. Any Third Party involved in a Change of Control as set forth in the foregoing subclause (ii) of this Section 13.1 and such Third Party’s Affiliates immediately prior to such Change of Control shall be referred to herein as the “Acquirer”. Notwithstanding the foregoing, in the event that a Change of Control with respect to ZEALAND pursuant to the foregoing (ii) involves a Competitor, then ZEALAND shall promptly notify ALEXION of such contemplated Change of Control, but in any event within [***] Business Days prior to [***] with respect to such contemplated Change of Control, and ALEXION shall have the right to terminate this Agreement in accordance with Section 12.2.1.

This Agreement may be amended only by an instrument in writing duly executed on behalf of the Parties. In case of inconsistencies between this Agreement and any Appendix hereof, the terms of this Agreement shall prevail unless agreed to explicitly that the Appendix should prevail.

13.3 Force Majeure. Neither Party shall be liable or deemed in default for failure to perform any duty or obligation that such Party may have under this Agreement where such failure has been occasioned by any act of God, fire, external strike, inevitable accidents, war, or any other cause outside the reasonable control of that Party, and occurring without its fault or negligence; provided that the Party affected will promptly notify the other of the force majeure condition and will exert all reasonable efforts to eliminate, cure or overcome any such causes and to resume performance of its obligations as soon as possible.

13.4 Waiver. The failure of either Party to require performance by the other Party of any of that other Party’s obligations under this Agreement shall in no manner affect the right of such Party to enforce the same at a later time. No waiver by any Party of any condition, or of the breach of any provision, term, representation or warranty contained in this Agreement shall be deemed to be or construed as a further or continuing waiver of any such condition or breach, or of any other condition or of the breach of any other provision, term, representation, or warranty hereof.

In any such event, this Agreement shall be construed as if such provision or portion thereof had never been contained in this Agreement, and there shall be deemed substituted therefore such provision as will most nearly carry out the intent of the Parties as expressed in this

Agreement to the fullest extent permitted by Applicable Law unless doing so would have the effect of materially altering the right and obligations of the Parties in which event this Agreement may be terminated by mutual written agreement of the Parties.

Alexion and Zealand Pharma Announce Collaboration to Discover and Develop Peptide Therapies for Complement-Mediated Diseases

· Collaboration furthers Alexion’s complement leadership with expansion into peptide therapies.

· Agreement provides Alexion with exclusive worldwide licenses for one preclinical target, with option for up to three additional targets, in the complement pathway.

· Zealand Pharma to receive upfront payment of $25 million and equity investment of $15 million, with potential for additional milestone-dependent and royalty payments.

· Collaboration further strengthens Zealand Pharma’s position as a leading developer of next generation peptide-based therapeutics.

BOSTON & COPENHAGEN, Denmark, March 20, 2019 - Alexion Pharmaceuticals, Inc. (NASDAQ: ALXN) and Zealand Pharma A/S (NASDAQ: ZEAL) today announced a collaboration to discover and develop novel peptide therapies for complement-mediated diseases. Peptides offer a number of advantages, including being highly selective and potent, allowing low dosage volumes for ease of administration, and having the potential to treat a broad range of complement-mediated diseases. The agreement provides Alexion with exclusive worldwide licenses, as well as development and commercial rights, for up to four targets within the complement pathway.

“We know that uncontrolled activation of the complement pathway is responsible for many devastating diseases, and through the development of the first two complement inhibitors — SOLIRIS and ULTOMIRIS — we have shown the transformative impact of C5 inhibition on several of these diseases,” said John Orloff, M.D., Executive Vice President and Head of Research & Development at Alexion. “We are excited by the potential to explore different targets in the complement pathway and look forward to building on Alexion’s more than 20 years of complement expertise with the development of next-generation peptide therapies in collaboration with Zealand Pharma, which may provide the opportunity to treat many additional diseases.”

“Collaborating with Alexion is further evidence of the strength of our peptide discovery platform, which has delivered both approved novel peptide-based therapeutics and a deep late-stage pipeline,” said Adam Steensberg, Interim CEO and Chief Medical and Development Officer at Zealand. “We believe that peptide-based therapies hold great promise in inhibiting complement activation. Alexion’s demonstrated expertise in treating rare and complement-mediated diseases makes this the ideal collaboration to advance Zealand’s complement-focused peptide programs.”

Under the terms of the agreement, Alexion and Zealand will enter into an exclusive collaboration for the discovery and development of subcutaneously delivered peptide therapies directed to up to four complement pathway targets. Zealand will lead the joint discovery and research efforts through the preclinical stage, and Alexion will lead development efforts beginning with IND filing and Phase 1 studies. The agreement provides Alexion with exclusive worldwide licenses and commercial rights to the peptide therapies developed in the collaboration. Zealand will receive an immediate upfront payment of $25 million for the first target, with Alexion making a concurrent $15 million equity investment in Zealand Pharma at a premium to the market price as of the collaboration effective date. For the lead target, the agreement provides the potential for development-related milestones of up to $115 million, as well as up to $495 million in sales-related milestones and the potential for high single- to low double-digit royalty payments. Each of the three subsequent targets can be selected for an option fee of $15 million and has the potential for additional development-milestones and sales-milestones and royalty payments at a reduced price to the lead target.

Alexion will discuss the collaboration further during today’s Investor Day event and webcast. Zealand will host a conference call on Thursday, March 21, at 4 p.m. CET.
