Re: Exclusivity Letter 
 Ladies and Gentlemen: 

In connection with a possible broader business transaction (a “Transaction”) involving Unilife Corporation
(“Unilife”) and Amgen Inc. (“Amgen” and, together with Unilife, the “Parties”), the Parties hereby agree as follows: 

1. In order to induce Amgen to make the Deposit (as defined below) and to devote additional time and resources to its continuing evaluation
and, if applicable, pursuit of a Transaction, and in consideration therefor: 
 (a) Exclusivity. Subject to Unilife’s timely
receipt of the Deposit (as defined below), from the date of this letter agreement (this “Agreement”) until the earlier of (x) 11:59pm Pacific time on January 31, 2016 and (y) the time at which Amgen notifies Unilife
in writing that Amgen has ceased to consider a Transaction (such time period, the “Exclusivity Period”), Unilife agrees that it shall not, and it shall cause its controlled Affiliates (as defined below) and its and their respective
directors, officers, employees, attorneys, accountants, financial advisors, agents and other professional representatives (collectively, “Representatives”) not to, directly or indirectly: 

i. solicit, initiate, induce, facilitate, assist or knowingly encourage the making of any inquiry, indication of interest,
proposal, offer or announcement concerning or contemplating, or that could reasonably be expected to lead to, any Alternative Transaction (as defined below) (any of the foregoing, a “Proposal”); 

ii. furnish any information (including through providing or continuing access to any data room) regarding Unilife or any of its
Subsidiaries to any Person in connection with a Proposal; 
 iii. participate or engage in or continue discussions or
negotiations with any Person with respect to a Proposal; 
 iv. enter into any letter of intent, term sheet, merger
agreement, acquisition agreement, license agreement, option agreement or similar document or any agreement, arrangement or understanding contemplating or otherwise relating to any Alternative Transaction; 

  
 1 

 v. release or permit the release during the Exclusivity Period of any Person
(other than Amgen) from, or waive or permit the waiver of any provision of, or fail to enforce or cause to be enforced, any confidentiality, “standstill”, or similar agreement to which Unilife or any of its Subsidiaries is a party; 

vi. otherwise facilitate any effort or attempt by any Person to make any Proposal; or 

vii. commence any proceeding in bankruptcy or otherwise initiate any insolvency or debtor-creditor proceedings. 

To the extent Unilife is not prohibited by a confidentiality agreement or other contractual obligation, in each case in effect on the date
hereof, from doing so, Unilife agrees to notify Amgen promptly (and in any event no later than 24 hours) after receipt by the Company or any of its controlled Affiliates or its or their Representatives, of any Proposal or any request for information
or access to members of management or the board of directors of Unilife in connection with any Proposal, and Unilife shall provide Amgen with a copy of any such Proposal or request, or if not in writing, a written description thereof, including the
name of the Person making such Proposal or request and the proposed purchase price or other transaction consideration. During the Exclusivity Period, Amgen agrees to promptly notify Unilife in writing if Amgen ceases to consider a Transaction. 

As used in this Agreement: (i) the term “Person” shall be broadly interpreted to include any corporation, company,
group, partnership, joint venture, limited liability company, trust, governmental entity, other entity of any kind or nature, or individual; (ii) the term “Affiliate” shall have the meaning ascribed to such term in
Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934, as amended; (iii) the term “Alternative Transaction” shall mean any transaction or series of transactions (other than a transaction
solely with Amgen and/or any of its controlled Affiliates and other than the issuance of common stock or the redemption of preferred stock pursuant to existing obligations under Unilife’s agreement with its preferred stock investor (including
those under Unilife’s Certificate of Designations of Preferences, Powers, Rights and Limitation of Series A Redeemable Convertible Preferred Stock)) involving: (x) the purchase of any capital stock or other equity interest in, or any of
the businesses of, Unilife or any of its Subsidiaries, (y) any merger, share exchange, tender offer, business combination, consolidation, joint venture, restructuring, reorganization, recapitalization, spin-off, split-off or other alternative
transaction involving any capital stock, businesses or assets of Unilife or any of its Subsidiaries, or (z) any direct or indirect sale, license, lease, transfer, pledge, exchange or other disposition of any material portion of the assets or
liabilities of Unilife or any of its Subsidiaries, including any amendment to an existing agreement to do any of the foregoing and including any exclusive license involving any Unilife delivery devices, delivery platforms or the intellectual
property related thereto; and (iv) the term “Subsidiary” means, as to any Person, any other Person of which such Person directly or indirectly (through one or more subsidiaries) owns or controls (x) at least a majority of
the outstanding equity or economic interests or (y) securities or ownership interests having by their terms ordinary voting power to elect at least a majority of the board of directors or other Persons performing similar functions.

 During the Exclusivity Period, Unilife shall, and it shall cause its controlled Affiliates and
its and their Representatives to, immediately cease any discussions or negotiations with, or any solicitation, knowing encouragement or assistance of, any Person, in each case that may be ongoing with respect to any Alternative Transaction or any
Proposal. 
 (b) Negotiation. During the Exclusivity Period, Unilife and Amgen shall negotiate in good faith, subject to (including
without limitation) Amgen’s rights to conduct diligence and to notify Unilife in the event Amgen ceases to consider a Transaction, regarding a Transaction that would include: 

(i) xxx

 5. This Agreement shall be governed by, and construed in accordance with, the internal laws of
the State of New York, without regard to the conflict of laws principles thereof to the extent that such principles would direct a matter to another jurisdiction. The Parties agree that any lawsuit filed by one Party against the other in connection
with this Agreement shall be heard by the federal or state courts located in New York (the “Chosen Courts”), which shall have exclusive jurisdiction over any such lawsuits, and the Parties hereto agree to submit to the jurisdiction
of those courts. Each Party agrees that a final judgment in any lawsuit, action or other proceeding arising out of or relating to this Agreement brought in the Chosen Courts shall be conclusive and binding upon each of the Parties and may be
enforced in any other courts the jurisdiction of which each of the Parties is or may be subject, by suit upon such judgment. 
 6. Unilife
agrees that irreparable damage could occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, without prejudice to any other
remedies to which Amgen may be entitled at law or in equity, Amgen shall be entitled to seek equitable relief, including an injunction and/or specific performance, in the event of any breach (or threatened breach) of the provisions of this
Agreement, without proof of damages. Unilife agrees that it shall not seek, and that it and its controlled Affiliates shall agree to waive any requirement for (and shall use its best efforts to cause its Representatives to waive any requirement),
the securing or posting of a bond in connection with Amgen’s seeking or obtaining such relief. 
 7. No failure or delay by Amgen in
exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege. 

8. It is understood and agreed that if any provision contained in this Agreement or the application thereof to either Party, or any other
Person or circumstance shall be invalid, illegal or unenforceable in any respect under any applicable law as determined by a court of competent jurisdiction, the validity, legality and enforceability of the remaining provisions contained in this
Agreement, or the application of such provision to such Persons or circumstances other than those as to which it has been held invalid or unenforceable, shall remain in full force and effect and shall in no way be affected, impaired or invalidated
thereby. In the case of any such invalidity, illegality or unenforceability, a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or
unenforceable provision. Time is of the essence with respect to all provisions of this Agreement.
