	  	 	May 9, 2016	  
		  	 	Mountain View, CA	  

 FOR VALUE RECEIVED,
ALEXZA PHARMACEUTICALS, INC., a Delaware corporation (“Borrower”), hereby promises to pay to the order of GRUPO FERRER
INTERNACIONAL, S.A., a company organized under the laws of Spain (“Lender”), in lawful money of the United States of America (“Dollars”), the principal sum of Six Million Three
Hundred Thousand Dollars ($6,300,000) (the “Loan”), or such lesser amount as may be outstanding or advanced from time to time under this Note, together with accrued and unpaid interest thereon, each due and payable on the
dates and in the manner set forth below. Borrower and Lender are parties to that certain Promissory Note, dated as of September 28, 2015 (as heretofore amended, the “Prior Note”) which they desire to amend and restate to
accept the rights and obligations hereof in lieu of their rights and obligations under the Prior Note. 
 1. Principal Repayment. The
outstanding principal amount of the Loan shall be due and payable on September 30, 2016 (the “Maturity Date”). 

2. Interest Rate. Borrower further promises to pay interest on the outstanding principal amount hereof from September 28, 2015
until payment in full, which interest shall be payable at the rate of six percent (6%) per annum. Interest shall compound monthly and be due and payable on demand on the Maturity Date and shall be calculated on the basis of a 365-day year for
the actual number of days elapsed. Notwithstanding the foregoing, interest shall accrue from September 28, 2015 upon the First Tranche (as defined below), interest shall accrue from March 21, 2016 on the Second Tranche (as defined below),
interest shall accrue from April 15, 2016 on the Third Tranche (as defined below), interest shall accrue from May 9, 2016 on the Fourth Tranche (as defined below). 

3. Place of Payment. All amounts payable hereunder shall be payable at the office of Lender, Av. Diagonal 549, E-08029 Barcelona,
Spain, unless another place of payment shall be specified in writing by Lender. 
 4. Prepayment. Borrower may prepay this Note at
any time without premium or penalty. 

  
 1. 

 5. Application of Payments. Payment on this Note shall be applied first to accrued
interest, and thereafter to the outstanding principal balance hereof. 
 6. Loan Requests. Lender previously made available to
Borrower a loan of Three Million Dollars ($3,000,000) (the “First Tranche”), a second loan of One Million Dollars ($1,000,000) (the “Second Tranche”) and a third loan of One
Million Dollars ($1,000,000) (the “Third Tranche”) of the principal amount indicated on the face of this Note for borrowings by Borrower. Substantially concurrently with the execution hereof, Lender has made
available to Borrower a fourth loan of One Million Three Hundred Thousand Dollars ($1,300,000) (the “Fourth Tranche”) of the principal amount indicated on the face of the Note for borrowings by Borrower.
Borrower shall notify Lender by facsimile transmission or telephone no later than 4:00 p.m. Pacific time, four (4) business days prior to the date on which the loan is requested to be made. At the time of any borrowing under this Note (or at
the time of receipt of any payment of principal), Lender shall make or cause to be made, an appropriate notation on the EXHIBIT A attached hereto reflecting the amount of such borrowing (or the amount of such payment). The
outstanding amount of this Note set forth on such EXHIBIT A shall be prima facie evidence of the principal amount thereof outstanding, but the failure to record, or any error in so recording, shall not limit or otherwise affect
the obligations of Borrower to make payments of principal of or interest on this Note when due. Borrower and Lender hereby acknowledge that the initial principal amount outstanding under this Note as of the date hereof shall be Six Million Three
Hundred Thousand Dollars ($6,300,000), as indicated on the attached EXHIBIT A, and the maximum principal amount of loans under this Note shall not exceed Six Million Three Hundred Thousand Dollars ($6,300,000).  

7. Stock Issuance. As additional consideration for the Loan (as defined under the Prior Note), the Borrower issued to Lender
one-hundred and twenty-five thousand (125,000) shares of Borrower’s common stock, par value $0.0001 per share under the Prior Note. 

8. Default. Each of the following events shall be an “Event of Default”
hereunder: 
 (a) Borrower fails to pay timely any of the principal amount due under this Note or any accrued interest
or other amounts due under this Note on the date the same becomes due and payable or within ten (10) business days thereafter; 

(b) Borrower files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other
law for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any corporate action in furtherance of any of the foregoing; 

(c) An involuntary petition is filed against Borrower (unless such petition is dismissed or discharged within sixty (60) days)
under any bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is appointed to take possession, custody or control of any property of Borrower; 

 (d) Borrower fails to duly execute and deliver to Lender and Ferrer Pharma Inc. a counterpart
signature page to the Agreement and Plan of Merger, by and among Lender, Ferrer Pharma Inc. and Borrower in the form attached hereto as EXHIBIT B (the “Merger Agreement”)
within three (3) business days following the date hereof; or 

  
 2. 

 (e) The termination of the Merger Agreement in accordance with its terms. 

Upon the occurrence of an Event of Default hereunder, all unpaid principal, accrued interest and other amounts owing hereunder shall, at the option of Lender,
and, in the case of an Event of Default pursuant to (b), (c) or (e) above, automatically, be immediately due, payable and collectible by Lender pursuant to applicable law. 

9. Waiver. Borrower waives presentment and demand for payment, notice of dishonor, protest and notice of protest of this Note, and
shall pay all costs of collection when incurred, including, without limitation, reasonable attorneys’ fees, costs and other expenses. 

The right to plead any and all statutes of limitations as a defense to any demands hereunder is hereby waived to the full extent permitted by
law. 
 10. Governing Law. This Note shall be governed by, and construed and enforced in accordance with, the laws of the State of
New York, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction. 
 11. Taxes.
Borrower shall deduct and withhold from payments due pursuant to this Note any taxes required to be deducted and withheld under applicable law. Any such withheld taxes shall be timely paid over to the appropriate governmental authority in accordance
with applicable law. To the extent that taxes are deducted and withheld from payments otherwise payable pursuant to this Note, and are paid to the appropriate governmental authority, such deducted and withheld amounts shall be treated for all
purposes of this Note as having been paid to the person in respect of whom such deduction and withholding was made. Borrower shall provide such person with proof reasonably satisfactory to such person of any taxes withheld and paid to any
governmental authority on behalf of such person. On or prior to the date hereof, Lender shall deliver to Borrower (i) two executed originals of the applicable IRS Form W-8, and (ii) to the extent Lender is eligible for an exemption from or
reduction of any otherwise applicable withholding tax, any other applicable documentation required or reasonably requested by Borrower to establish that Lender is entitled to such exemption or reduction. As soon as reasonably practicable following
any transfer by Lender of the Note to an assignee (or any other successor to Lender’s interest in the Note), such assignee or successor, as applicable, shall deliver to Borrower (i) in the case such assignee or transferee is a United
States person (as defined in Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended, (the “Code”)) (a “U.S. Person”), two executed originals of IRS Form W-9 certifying that such
assignee or successor is not subject to U.S. federal backup withholding, or (ii) in the case such assignee or transferee is not a U.S. Person, (a) two executed originals of the applicable IRS Form W-8, and (b) to the extent such
assignee or transferee is eligible for an exemption from or reduction of any otherwise applicable withholding tax, any other applicable documentation required or reasonably requested by Borrower to establish that such assignee or transferee is
entitled to such exemption or reduction. Lender, its assignees, transferees and Borrower shall use commercially reasonable efforts to establish any applicable exemption from or reduction of otherwise applicable withholding taxes with respect to
payments made hereunder. If any 

  
 3. 

 
payment hereunder to a non-U.S. Person is subject to Sections 1471-1474 of the Code (“FATCA”), the applicable non-U.S. Person shall provide Borrower with all documentation prescribed by
applicable law or reasonably requested by Borrower in order for Borrower to comply with its obligations under, and determine the amount, if any, of withholding taxes imposed pursuant to FATCA. 

12. Original Issue Discount. The “issue price” for the First Tranche issued pursuant to this Note equaled (i) the face
value of the Lender’s interest in the portion of the Loan associated with the First Tranche, minus (ii) the Stock Value (as defined below). Lender and Borrower agree (x) that the portion of the Loan associated with the First Tranche
is part of an investment unit issued within the meaning of Section 1273(c)(2) of the Code, which also includes the stock issued pursuant to Section 7 of this Note, (y) that the allocation provided in this Section 12 will be used
for purposes of Section 1273(c)(2) of the Code and (z) to use the foregoing issue prices for all applicable Tax purposes with respect to this transaction, except as otherwise required by applicable law. Borrower and Bank agree to make any
determinations under Treasury Regulations §1.1273-2(h)(2) consistent with the foregoing and to file all required tax returns consistently with the foregoing, as applicable, except as otherwise required by applicable law. Lender and Borrower
hereby agree (i) that the Stock Value associated with the First Tranche was $143,750.00, (ii) to consistently apply the Stock Value for all tax and information reporting purposes, and (iii) to take no action inconsistent with the
Stock Value for such purposes unless otherwise required by applicable law. 
 13. Mutual Waiver of Jury Trial.
BORROWER AND LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF THIS NOTE OR ANY RELATED DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER
CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS NOTE. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 

14. Successors and Assigns. The provisions of this Note shall inure to the benefit of and be binding on any successor to Borrower and
shall extend to any holder hereof, provided however that the right to receive principal and/or interest payments may be assigned or transferred only by (i) surrender of this Note to Borrower and (a) reissuance by Borrower of this Note to
the new holder or (b) issuance by Borrower of a new note to the new holder, or (ii) notification to Borrower of the transfer and a change by Borrower in Borrower’s books and records identifying the new owner of an interest in the
principal or interest on this Note. Borrower shall at all times maintain a book-entry system, which shall reflect ownership of this Note and interests therein.

 ARTICLE I

 Section
1.1 The Offer

practicable, and in any case within ten (10) Business Days, following the date hereof, Merger Sub shall, and Parent shall cause Merger Sub to, commence, within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together
with the rules and regulations promulgated thereunder, the “Exchange Act”), the Offer; provided, that 

  
 2 

 
the Company agrees that no shares of Company Common Stock owned by the Company or any Company Subsidiary will be tendered pursuant to the Offer. The obligations of Merger Sub to, and of
Parent to cause Merger Sub to, accept for payment, and pay or cause to be paid for, any shares of Company Common Stock tendered pursuant to the Offer are subject only to the satisfaction or waiver (to the extent permitted under this Agreement) of
the conditions set forth in Exhibit A (as they may be amended in accordance with this Agreement, the “Offer Conditions”). Merger Sub expressly reserves the right, at any time, to, in its sole discretion, waive, in
whole or in part, any Offer Condition or modify the terms of the Offer; provided, however, that, without the prior written consent of the Company, Merger Sub shall not (i) reduce the number of shares of Company Common Stock subject to the
Offer, (ii) reduce the Offer Price or change the form of consideration payable in the Offer, (iii) change, modify or waive the Minimum Tender Condition, (iv) add to the conditions set forth in Exhibit A or modify or change any Offer Condition
in a manner adverse to any holders of Company Common Stock (other than Parent and its Subsidiaries) or (v) otherwise amend the Offer in any manner adverse to the holders of Company Common Stock (other than Parent and its Subsidiaries) other than in
immaterial respects. 
 (b) Expiration of the Offer. The Offer shall expire at midnight at the end of the date that is twenty
(20) business days after the commencement of the Offer (determined using Rule 14d-1(g)(3) of the Exchange Act) (such time, or such subsequent time to which the expiration of the Offer is extended in accordance with the terms of this Agreement, the
“Expiration Time”); provided, however, that, subject to the provisions of Article VIII, (i) if at the Expiration Time, any Offer Condition shall not have been satisfied or waived (to the extent permitted under
applicable Law), Merger Sub may, in its sole discretion, without the consent of the Company, extend the Offer for one or more consecutive increments of not more than ten (10) Business Days each (the length of such period to be determined by Parent
or Merger Sub), until the earlier of (A) the termination of this Agreement in accordance with its terms and (B) the Outside Date and (ii) if at the Expiration Time, any Offer Condition shall not have been satisfied or waived (to the extent permitted
under applicable Law), Merger Sub shall (and Parent shall cause Merger Sub to) extend the Offer at the request of the Company for one or more consecutive increments of not more than ten (10) Business Days each (the length of such period to be
determined by Parent or Merger Sub after consultation with the Company), until the earlier of (A) the termination of this Agreement in accordance with its terms and (B) the Outside Date. Merger Sub shall extend the Offer for any period required
by any rule, regulation, interpretation or position of the United States Securities and Exchange Commission (the “SEC”), the staff thereof or the NASDAQ Stock Market (“NASDAQ”) applicable to the Offer
or as may be required by any other Governmental Entity; provided, that Merger Sub shall not be required to extend the Offer to a date later than the Outside Date. Nothing contained in this Section 1.1(b) shall affect any termination
rights in Article VIII. 
 (c) Offer Closing. On the terms and subject to the conditions of this Agreement (including the
satisfaction or waiver of the conditions set forth in Exhibit A), Merger Sub shall, and Parent shall cause Merger Sub to, (i) accept for payment all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the
Offer prior to 9:00 a.m. New York City time, on the business day (determined using Rule 14d-1(g)(3) of the Exchange Act) immediately following the Expiration Time and (ii) pay or cause to be paid for all such shares (subject to any applicable Tax
withholding pursuant to Section 3.2(h)) as soon as 

  
 3 

 
practicable after the Expiration Time. The Offer Price payable in respect of each share of Company Common Stock pursuant to the preceding sentence shall be paid net to the holder thereof in
cash, without interest, on the terms and subject to the conditions of this Agreement. Acceptance for payment of shares of Company Common Stock pursuant to and subject to the conditions of the Offer upon the expiration of the Offer is referred
to in this Agreement as the “Offer Closing,” and the date on which the Offer Closing occurs is referred to in this Agreement as the “Offer Closing Date.” 

(d) Schedule TO; Offer Documents. On the date of commencement of the Offer, Parent and Merger Sub shall file with the SEC a
Schedule TO (or, if the filing of a Rule 13E-3 Transaction Statement is required by law or failure to make such filing would reasonably be expected to materially delay the Offer Closing, a combined Tender Offer Statement and Rule 13E-3 Transaction
Statement under cover of Schedule TO) with respect to the Offer (together with all amendments and supplements thereto and including exhibits thereto, the “Schedule TO”), which shall contain an offer to purchase and a related
letter of transmittal and summary advertisement, a notice of appraisal rights as contemplated by Section 262(d)(2) of the DGCL and other appropriate ancillary offer documents (such Schedule TO and the documents included therein pursuant to which the
Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”), and cause the Offer Documents to be disseminated to the stockholders of the Company as and to the extent required by United
States federal securities Laws and the DGCL. Parent and Merger Sub shall cause the Schedule TO to comply in all material respects with the Exchange Act, the DGCL and all other applicable Law. The Company shall promptly furnish to Parent
and Merger Sub all information concerning the Company required by the Exchange Act to be set forth in the Offer Documents. Each of Parent, Merger Sub and the Company shall promptly correct any information supplied by it for inclusion or
incorporation by reference in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent, Merger Sub and the Company shall take all steps necessary to amend or
supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and disseminated to the stockholders of the Company, in each case as soon as reasonably practicable and as and to the extent
required by applicable United States federal securities Laws. Parent and Merger Sub shall promptly notify the Company upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Offer
Documents, and shall promptly provide the Company with copies of all correspondence between them and their Representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Offer Documents (including any amendment or
supplement thereto) with the SEC or dissemination thereof to the stockholders of the Company, or responding to any comments of the SEC with respect to the Offer Documents, Parent and Merger Sub shall provide the Company and its counsel a reasonable
opportunity to review and comment on such Offer Documents or response, and Parent and Merger Sub shall give reasonable, good faith consideration to any such comments. 

(e) At or prior to the Offer Closing Date, Parent will authorize and duly adopt, execute and deliver, and will ensure that a duly qualified
Rights Agent executes and delivers, a Contingent Value Rights Agreement in substantially the form attached hereto as Exhibit B, subject to any reasonable revisions to such Contingent Value Rights Agreement that are requested by such Rights
Agent (provided that such revisions are not, individually or in the aggregate, detrimental to any CVR holder, other than in immaterial respects) (the “CVR Agreement”). 

  
 4 

 (f) Parent shall provide or cause to be provided to Merger Sub on a timely basis the
consideration necessary to pay or cause to be paid for any shares of Company Common Stock that Merger Sub becomes obligated to accept for payment, and pay or cause to be paid for, pursuant to the Offer. 

(g) Parent and Merger Sub shall make adequate provision such that if, immediately prior to the Expiration Time, (i) the Minimum Tender
Condition has been satisfied but (ii) the aggregate number of shares of Company Common Stock that have been validly tendered (not including shares tendered pursuant to procedures for guaranteed delivery and not actually received by the depository
prior to the Expiration Time) and not validly withdrawn by the Company’s stockholders (excluding, for the avoidance of doubt, any shares of Company Common Stock already owned by Parent, Merger Sub or any of their respective Subsidiaries) does
not represent at least a majority of the total number of shares of Company Common Stock outstanding immediately prior to the Offer Closing, Merger Sub shall, prior to the Expiration Time, acquire a sufficient number of shares of Company Common Stock
held by Parent and/or its Subsidiaries (excluding Merger Sub) such that, immediately following such acquisition, the sum of (x) the number of shares of Company Common Stock so acquired and (y) the aggregate number of shares of Company Common Stock
that have been validly tendered (not including shares tendered pursuant to procedures for guaranteed delivery and not actually received by the depository prior to the Expiration Time) and not validly withdrawn by the Company’s stockholders
represents at least a majority of the total number of shares of Company Common Stock outstanding immediately prior to the Offer Closing.

(a) The Company hereby approves and consents to the Transactions. The Company represents that it has been advised that all of its directors and
all of its named executive officers (as defined in the Company’s most recent Form 10-K/A) who own shares of Company Common Stock and who remain directors of, or employed by, the Company (as the case may be) as of the date hereof intend to
tender such shares pursuant to the Offer. 
 (b) To the extent reasonably practicable, on the date the Offer Documents are filed with the
SEC (and, in any event, within one (1) Business Day thereof), the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, together with any supplements or amendments
thereto, the “Schedule 14D-9”) containing the Company Recommendation and, if the filing of a Transaction Statement on Schedule 13E-3 is required by law of failure to make such filing would reasonably be expected to materially

and, if applicable, the Schedule 13E-3 to the stockholders of the Company as and to the extent required by Rule 14d-9 and Rule 13e-3, respectively, under the Exchange Act. The Company shall cause the Schedule 14D-9 and, if applicable, the
Schedule 13E-3 to comply in all material respects with the Exchange Act and all other applicable Law. Parent and Merger Sub shall promptly furnish to the 

  
 5

Parent and Merger Sub shall promptly correct any information supplied by it for inclusion or incorporation by reference in the Schedule 14D-9 and/or, if applicable, the Schedule 13E-3 if and to the extent that such information shall have become
false or misleading in any material respect, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and/or, if applicable, the Schedule 13E-3 and to cause the Schedule 14D-9 and/or, if applicable, the Schedule 13E-3

Laws. The Company shall promptly notify Parent upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Schedule 14D-9 and/or, if applicable, the Schedule 13E-3, and shall promptly provide
Parent with copies of all correspondence between the Company and its Representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Schedule 14D-9 and, if applicable, the Schedule 13E-3 (including any amendment or
supplement thereto) with the SEC or mailing thereof to the stockholders of the Company, or responding to any comments of the SEC with respect to the Schedule 14D-9 and/or, if applicable, the Schedule 13E-3, the Company shall provide Parent and its
counsel a reasonable opportunity to review and comment on such Schedule 14D-9, if applicable, Schedule 13E-3 or response, and the Company shall give reasonable and good faith consideration to any such comments. The Company hereby consents to
the inclusion in the Offer Documents of the Company Recommendation. 
 (c) In connection with the Offer and the Merger, the Company shall
cause its transfer agent to furnish Parent and Merger Sub promptly, and in any event within five (5) Business Days of the date hereof, with mailing labels containing the names and addresses of the record holders of Company Common Stock as of the
latest practicable date and of those persons becoming record holders subsequent to such date, together with copies of all lists of stockholders, security position listings and computer files and all other information in the Company’s possession
or control regarding the beneficial owners of shares of Company Common Stock, in each case as of the latest date practicable, and shall furnish to Parent and Merger Sub such information and assistance (including periodically updated lists of
stockholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to holders of Company Common Stock. Subject to the requirements of applicable Law, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate the Offer and the Merger, Parent and Merger Sub and their agents (x) shall hold in confidence the information contained in any such labels, listings and files and will
use such information only in connection with the Offer and the Merger and (y) following the termination of this Agreement, shall promptly, at the election of Parent, deliver to the Company or destroy, and will use their reasonable best efforts to
cause their agents to deliver to the Company or destroy, all copies and any extract or summaries of such information then in their possession or control and promptly certify to the Company in writing that all such material has been so returned or
destroyed.

represented outstanding shares of Company Common Stock (the “Certificates”) or (ii) uncertificated shares of Company Common Stock represented by book-entry (the “Uncertificated Shares”),
in each case, which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 3.1, (A) a letter of transmittal in customary form (which, in the case of Certificates, shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (B)
instructions for use in effecting the surrender of the Certificates or Uncertificated Shares in exchange for the Merger Consideration. Upon (1) surrender of Certificates for cancellation to the Paying Agent or receipt of an “agent’s
message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, together with such letter of transmittal, duly completed and
validly executed in accordance with the instructions thereto and (2) such other documents as may reasonably be required by the Paying 

  
 9 

 
Agent, the holder of such Certificates or Uncertificated Shares shall be entitled to receive in exchange therefor the amount of the Merger Consideration to which such holder is entitled pursuant
to Section 3.1, and any Certificates so surrendered shall forthwith be cancelled. If the Merger Consideration (including, for the avoidance of doubt, payment in the form of or with respect to the CVRs) is to be paid to any Person other
than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form
for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered
holder of such Certificate or Uncertificated Share or establish to the satisfaction of Parent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 3.2(b), each share of Company Common Stock
represented by a Certificate or Uncertificated Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon such surrender. 

(c) No Further Ownership Rights in Company Common Stock. The Merger Consideration paid upon the surrender for exchange of
Certificates or Uncertificated Shares in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such
Certificates or Uncertificated Shares. At the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the
shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Paying Agent for any reason,
they shall be cancelled and exchanged as provided in this Article III. 
 (d) Termination of Exchange Fund. Any portion
of the Exchange Fund which remains undistributed to the holders of Company Common Stock six (6) months after the Effective Time shall be delivered to Parent, within two (2) Business Days of the expiration of such six (6) month period, and any
holders of Company Common Stock who have not theretofore complied with this Article III shall thereafter look only to Parent for payment of their claim for the Merger Consideration, subject to subsection (e) below. 

(e) No Liability. None of Parent, Merger Sub, the Company and the Paying Agent or any of their respective directors, officers,
employees and agents shall be liable to any Person in respect of Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate or Uncertificated Share shall not
have been surrendered prior to six (6) years after the Effective Time, any cash remaining in the Exchange Fund at that time shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all
claims or interests of any Person previously entitled thereto. 
 (f) Investment of Exchange Fund. If Parent determines to invest the
Exchange Fund, Parent shall cause the Paying Agent to invest the Exchange Fund in direct short-term obligations of, or obligations fully guaranteed by the full faith and credit of, the United States of America or in commercial paper obligations
rated A-1 or P-1 or better by Moody’s 

  
 10 

 
Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or a combination of the foregoing, and, in each case, with maturities not exceeding three (3) months or money
market mutual funds comprised of any of the foregoing. To the extent there are losses with respect to such investments or the Exchange Fund diminishes for any other reasons below the level required to make prompt cash payment of the aggregate funds
required to be paid pursuant to this Agreement, Parent shall, or shall cause Merger Sub or any other Subsidiary of Parent to, promptly deposit additional funds into the Exchange Fund such that the funds held in the Exchange Fund are thereafter
sufficient to satisfy the obligations of Parent and Merger Sub hereunder. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this
Article III shall promptly be paid to Parent. For income Tax purposes, Parent shall be treated as having earned any interest and other income resulting from the investment of the Exchange Fund. 

(g) Certain Adjustments. Without limiting the other provisions of this Agreement, in the event that, during the period between the
date hereof and the Effective Time, the number of outstanding shares of Company Common Stock or securities convertible or exchangeable into or exercisable for shares of Company Common Stock shall be changed into a different number of shares or
securities or a different class, including as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer, or other similar transaction,
then the Offer Price, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be equitably adjusted, without duplication, to reflect such change; provided that, in any case, nothing in this Section 3.2(g) shall
be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement. 

(h) Withholding. Parent, the Company, the Surviving Corporation, the Paying Agent and the Rights Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this Agreement, the CVR Agreement or otherwise such amounts as Parent, the Company, the Surviving Corporation, the Paying Agent or the Rights Agent, as applicable, is required to
deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Regulations promulgated thereunder, or any other provision of Tax Law. To the
extent that amounts are so withheld and paid over to the appropriate Governmental Entity by Parent, the Company, the Surviving Corporation, the Paying Agent or the Rights Agent, as applicable, such withheld amounts shall be treated for all purposes
as having been paid to the Person in respect of which such deduction and withholding was made. 
 (i) Lost, Stolen or Destroyed
Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making and delivery of an affidavit of that fact by
the holder thereof and delivery of a properly completed letter of transmittal to the Paying Agent, the Merger Consideration as may be required pursuant to Section 3.1(a); provided, however, that Parent may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver an agreement of indemnification in form reasonably satisfactory to Parent, or a bond in such sum as Parent may reasonably direct
as indemnity, against any claim that may be made against Parent or the Paying Agent in respect of the Certificates alleged to have been lost, stolen or destroyed. 

  
 11 

 Section 3.3 Dissenting Shares. Notwithstanding any provision of this Agreement to the
contrary, shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by holders of such shares of Company Common Stock who properly exercise appraisal rights with respect thereto in
accordance with Section 262 of DGCL (the “Dissenting Shares”) shall not be exchangeable for the right to receive the Merger Consideration, and holders of such Dissenting Shares will be entitled only to receive payment of the
appraised value of such shares of Company Common Stock in accordance with the provisions of such Section 262 unless and until such holders fail to perfect or effectively withdraw or lose their rights to appraisal and payment under the DGCL. If,
after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such shares of Company Common Stock will thereupon be treated as if they had been converted into and to have become exchangeable for, at the
Effective Time, the right to receive the Merger Consideration without any interest thereon. The Company shall give Parent (a) prompt notice of any demands received by the Company for appraisals of shares of Company Common Stock and (b) the
opportunity to jointly participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment (or agree to make any payment)
with respect to any demands for appraisal or offer to settle or settle any such demands. 
 Section 3.4 Treatment of Company Options and
Company Restricted Stock Awards. 
 (a) Company Options. Immediately prior to the Offer Closing, each option to purchase
shares of Company Common Stock granted under any Company Stock Plan (each, a “Company Option”) that is outstanding immediately prior to the Offer Closing shall be cancelled without consideration. In furtherance of the
foregoing, at least six (6) days prior to the expected Offer Closing, the Company shall accelerate the vesting and exercisability of all of the Company Options so that each holder of Company Options will have at least five (5) days to exercise any
then outstanding Company Options. In order to exercise the Company Options, the Company will require the holders of Company Options to deliver to the Company notice of exercise prior to the expected Offer Closing and for the exercise to occur at
least one (1) day prior to the occurrence of the Offer Closing. To the extent Company Options are exercised prior to the Offer Closing, they shall be treated as Company Common Stock pursuant to Section 3.1 of this Agreement. 

(b) Other Awards Under the Company Stock Plans. Each restricted share of Company Common Stock and restricted stock
unit related to a share of Company Common Stock granted under any Company Stock Plan (each, a “Company Restricted Stock Award”) that is outstanding immediately prior to the Offer Closing and that is not then fully vested
shall become fully vested immediately prior to the Offer Closing and, with respect to restricted stock units, the Company will deliver to the holders of restricted stock units all of the underlying shares of Company Common Stock (subject to any
applicable withholdings) in the form of Uncertificated Shares at least one (1) day prior to the Offer Closing. 
 (c) Company
Actions. Prior to the Offer Closing, the Company shall take all actions reasonably necessary (i) to effect the provisions of this Section 3.4 and to terminate, effective immediately prior to or as of the Offer Closing, all Company
Stock Plans and (ii) to 

  
 12 

 
ensure that no Person has any rights to acquire Company Common Stock or common stock of Parent or any of its Subsidiaries (including the Surviving Corporation), in each case, pursuant to any
Company Benefit Plan following the Offer Closing. Prior to the Offer Closing, the Company shall deliver notices (which notices shall have been approved by the Parent, in its reasonable discretion) to each holder of Company Options and Company
Restricted Stock Awards setting forth each holder’s rights pursuant to the Company Stock Plans and the terms of this Agreement, stating how the Company Options and Company Restricted Stock Awards shall be treated in connection with the
Transactions. 
 Section 3.5 Treatment of Warrants. 

(a) Warrants. Effective as of the Offer Closing, all Warrants outstanding immediately prior to the Offer Closing shall be cancelled
and, in consideration for such cancellation, each holder of a Warrant shall automatically (and without further action being required by such holders) receive (and Parent shall, or shall cause the Surviving Corporation or any Subsidiary of Parent to,
pay), at, or as soon as practicable following, the Offer Closing: 
 (i) in the case of the Out-Of-The-Money Warrants that are outstanding
immediately prior to the Offer Closing, a lump-sum cash payment equal to (A) the total number of shares of Company Common Stock issuable to such holder upon the exercise of the applicable Warrant, multiplied by (B) the value of such Warrant
to purchase one share of Company Common Stock, calculated in accordance with Appendix B of such Warrant, in each case without interest and subject to any applicable Tax withholding in accordance with Section 3.2(h); and 

(ii) in the case of any 2014 Warrant that is outstanding immediately prior to the Offer Closing, (i) a lump-sum cash payment equal to
(A) the total number of shares of Company Common Stock issuable to such holder upon the exercise of the applicable Warrant, multiplied by (B) the excess of (x) the Cash Consideration over (y) the per-share exercise price for such Warrant and (ii)
one (1) CVR for each share of Company Common Stock underlying such Warrant, in each case without interest and subject to any applicable Tax withholding in accordance with Section 3.2(h). 

(b) Company Actions. Prior to the Offer Closing, the Company shall take all actions reasonably necessary (i) to effect the
provisions of this Section 3.5 in compliance with all (or pursuant to a waiver of all applicable) terms and provisions, including any applicable notice provisions, of the Warrants, (ii) to ensure that no Person has any rights to acquire
Company Common Stock or common stock of Parent or any of its Subsidiaries (including the Surviving Corporation), in each case, pursuant to any Warrant following the Offer Closing and (iii) to cancel all Warrants effective at the Offer Closing. 

Section 3.6 Employee Stock Purchase Plan. Prior to the Offer Closing, the Company shall take all necessary and appropriate action such
that (a) no new purchase or offering period under the Company’s 2015 Employee Stock Purchase Plan (the “ESPP”) commences after the date hereof until termination of this Agreement or the Offer Closing such that if the
Offer Closing has not occurred prior to the end of the current offering period the Company shall suspend the ESPP until the Offer Closing, (b) each participant in the offering period currently in effect shall not increase his or her payroll
deductions or purchase elections 

  
 13 

 
from those in effect immediately prior to the date hereof, (c) if, with respect to an offering period in effect on the date hereof, the Offer Closing occurs prior to any Purchase Date (as defined
in the ESPP) for such offering period, then on a date to be determined by the Company in accordance with the terms of the ESPP (but no later than the day immediately prior to the Offer Closing) (the “Final Purchase Date”),
each purchase right under such offering that is outstanding as of the Final Purchase Date shall be used to purchase from the Company whole shares of Company Common Stock (subject to the terms of the offering and ESPP regarding the maximum number and
value of shares purchasable per participant) at the applicable price determined under the terms of the offering and ESPP (subject to the limitations set forth in clause (b) of this Section 3.6) for the then outstanding purchase or
offering period using such date as the final Purchase Date for such purchase or offering period, and any remaining accumulated but unused payroll deductions shall be distributed to the relevant participants without interest as promptly as
practicable following the Offer Closing, and (d) the ESPP is terminated at or prior to the Offer Closing.

contributed to or been obligated to sponsor, maintain or contribute to, or has any actual or contingent Liability under, any benefit plan that is (i) subject to Title IV of ERISA or Section 412 of the Code or is otherwise a defined benefit pension
plan or is a plan described in Section 3(40) of ERISA or Section 413 of the Code, a (ii) “multiple employer plan” (within the meaning of Section 413 of the Code) or (iii) a “multiple employer welfare arrangement” (within the
meaning of Section 3(40) of ERISA). No Liability under Title IV of ERISA or Sections 412 or 430 of the Code has been incurred by the Company or any Commonly Controlled Entity that has not been satisfied in full. 

(d) With respect to any Company Benefit Plan that is an employee welfare benefit plan, (i) no such Company Benefit Plan is funded through a
“welfare benefits fund” (as such term is defined in Section 419(e) of the Code), (ii) each such Company Benefit Plan that is a “group health plan” (as such term is defined in Section 5000(b)(1) of the Code) materially complies
with the applicable requirements of Section 4980B(f) of the Code and any applicable similar state or local Law except as has not had, and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect,
(iii) to the knowledge of the Company, each such Company Benefit Plan may be amended or terminated without material liability to the Company or any Company Subsidiary on or at any time after the Effective Time and (iv) no such Company Benefit Plan
provides benefits to, or on behalf of, any former employee after the termination of employment except (A) where the full cost of such benefit is borne entirely by the former employee (or such former employee’s eligible dependents or
beneficiaries) or (B) where the benefit is required by Section 4980B of the Code. 
 (e) Each material Company Benefit Plan has been
operated and administered in all material respects in accordance with its terms and with all applicable Laws, including ERISA and the Code. There are no pending and served, or to the knowledge of the Company, threatened audits, investigations,
actions or suits related to, by or on behalf of any Company Benefit Plan (other than routine claims for benefits). All material contributions, including participant contributions, and benefit payments required under each Company Benefit Plan

“disqualified person” with respect to any Company Benefit Plan has engaged in a non-exempt “prohibited transaction” within the meaning of Section 4975 of the Code or Section 406 of ERISA that would cause the Company or any
Company Subsidiary to incur any liability for any material amount. 
 (g) There are no understandings, agreements or undertakings, written
or oral, with any Person (other than pursuant to the express terms of the applicable Company Benefit Plan) that are (pursuant to any such understandings, agreements or undertakings) reasonably expected to result in any liabilities if such Company

and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect. Neither the Company nor any of its Subsidiaries has a contract, plan or commitment to create any additional Company Benefit Plan or to
modify any existing Company Benefit Plan, except as required by applicable Law or tax qualification requirement or as necessary to conform a Company Benefit Plan to applicable Law which would increase materially the expense of maintaining any
Company Benefit Plan. There have been no modifications of a Company Benefit Plans or creation of new Company Benefit Plans since the last audited company balance sheet that would be prohibited by the preceding sentence. The Company and its
Subsidiaries have not terminated any material Company Benefit Plan since the date of the last audited Company balance sheet.

pay or any retention, bonus, change in control or similar payments or benefits, (ii) result in, cause the accelerated vesting or delivery of, or increase the amount or value of, any payment or benefit to any Company Participant, (iii) trigger any

 34 

 (j) Neither the execution and delivery of this Agreement nor the consummation of the Transactions

confidentiality (provided, that the Company shall, upon the request of Parent, use its commercially reasonable efforts to obtain the required consent of any third party to such access or disclosure) or (iii) result

  
 51 

 
in the loss of attorney-client privilege (provided, that the Company shall use its commercially reasonable efforts to allow for such access or disclosure in a manner that does not result in a
loss of attorney-client privilege). No review pursuant to this Section 6.2 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the
obligations of the parties hereto under this Agreement. All information provided pursuant to this Section 6.2 shall be subject to the terms of the Confidentiality Agreement. 

Section 6.3 Notification of Certain Matters. Parent shall give prompt notice to the Company and the Company shall give prompt
notice to Parent, as the case may be, of the occurrence, or failure to occur, of any event, which occurrence or failure to occur is reasonably likely to cause (a)(i) any representation or warranty of such party contained in this Agreement that is
qualified as to “materiality,” or “Company Material Adverse Effect” to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement to be untrue or inaccurate in
any material respect, in each case at any time from and after the date hereof until the Offer Closing or (b) any material failure of Parent or Merger Sub or the Company, as the case may be, to comply with or satisfy any covenant, condition or

in connection with the Transactions. Notwithstanding the above, the delivery of any notice pursuant to this Section 6.3 shall not (i) cure any breach of, or non-compliance with, any other provision of this Agreement, (ii) limit or
otherwise affect the representations, warranties, covenants or agreements of the parties, or (iii) limit the remedies available hereunder to the party receiving such notice. 

Section 6.4 Reasonable Best Efforts. 

(a) Subject to Section 6.4(b), each of the parties to this Agreement agrees to use its reasonable best efforts to take, or cause to be
taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties to this Agreement in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner

 52 

 (b) Notwithstanding anything to the contrary in this Section 6.4 or any other provision of
this Agreement, Parent or its Affiliates shall not be required, and the Company and its Affiliates shall not agree with a Governmental Entity without prior consent of Parent, to divest any of its businesses, product lines or assets, hold separate or
take or agree to take any other action or agree to any limitation or restriction in order to resolve any objections asserted under any federal, state or foreign statute, rule, regulation, order, decree, administrative and judicial doctrine or other
Law that is designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization, restraint of trade, lessening of competition or foreign investment (including the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, the Sherman Act, as amended, the Clayton Act, as amended, and the Federal Trade Commission Act, as amended) by any Governmental Entity with respect to any of the Transactions if such action (i) would, or would reasonably be
expected to, materially and adversely affect the Company and the Company Subsidiaries, taken as a whole, (ii) would, or would reasonably be expected to, materially impair the benefits sought to be derived by Parent from the Transactions (taking into
account, among other things, effects on the assets, business and operations and relationships of both Parent and its Subsidiaries and of the Company and the Company Subsidiaries) or (iii) causes Parent to sell, divest, hold separate, license, cause
a third party to acquire, or otherwise dispose of any material operations, divisions, businesses, product lines, customers or assets of Parent or its Subsidiaries, or any other actions that may materially limit Parent’s freedom of action with
respect to, or its ability to retain, any of its Subsidiaries, material operations, divisions, businesses, product lines, customers or assets or agree to any other material limitation or restriction (with materiality in each case under this clause
(iii) being measured based on the size of the Company and the Company Subsidiaries, taken as a whole). 
 Section 6.5 No Solicitation;
Company Recommendation. 
 (a) The Company shall, and shall cause the Company Subsidiaries and the Company’s and the Company
Subsidiaries’ respective Representatives to, immediately cease and cause to be terminated any discussions or negotiations with any Person conducted heretofore with respect to a Company Takeover Proposal, and shall promptly thereafter request
the return from, or destruction by, all such Persons of all copies of confidential information previously furnished to such Persons by the Company, the Company Subsidiaries or the Company’s and the Company Subsidiaries’ respective
Representatives, in connection with exploring any Company Takeover Proposal prior to the date hereof and shall terminate access to any data room (electronic or otherwise) by any Person (other than Parent and its Representatives); provided
that, notwithstanding the foregoing, the Company shall not be required to terminate access to such portions of any data room (electronic or otherwise) by any Person identified in Section 6.1(b)(xiv) of the Company Disclosure Letter that are
reasonably necessary or useful to be reviewed by such Person in connection with any of the matters identified in Section 6.1(b)(xiv) of the Company Disclosure Letter. The Company shall not, and shall cause the Company Subsidiaries and
the Company’s and the Company Subsidiaries’ respective Representatives not to, directly or indirectly (i) solicit, initiate, knowingly facilitate or knowingly encourage (including by way of furnishing or providing access to non-public

 53 

 
inquiries or proposals that constitute, or which would reasonably be expected to lead to, a Company Takeover Proposal, (ii) participate in any discussions (other than to refer to this Agreement)

result from or arise in connection with a breach of this Section 6.5(a), and the Company Board determines in its good faith judgment (after consultation with outside counsel and a financial advisor of nationally recognized reputation) that
such Company Takeover Proposal constitutes, or would reasonably be expected to lead to, a Superior Proposal, then the Company may, if the Company Board determines (after consultation with outside counsel) that failure to take such actions would
constitute a breach of the Company Board’s fiduciary duties to the Company’s stockholders under applicable Law, and subject to compliance with this Section 6.5(a) and Section 6.5(b), at any time prior to the Offer Closing
Date (but in no event after the Offer Closing Date) and after providing Parent not less than two (2) Business Days prior written notice of such determination by the Company Board (A) furnish information with respect to the Company and the Company
Subsidiaries to the Person making such Company Takeover Proposal, but only after such Person enters into a customary confidentiality agreement and standstill agreement; provided, that (1) such confidentiality agreement may not include any
provision calling for an exclusive right to negotiate with the Company and (2) the Company provides Parent any non-public information with respect to the Company furnished to such other Person which was not previously furnished to Parent prior to
the time it is provided to such other Person, and (B) participate in discussions and negotiations with such Person regarding such Company Takeover Proposal. Without limiting the foregoing, it is understood that any violation of the foregoing
restrictions, or of any restrictions set forth in any other clause of this Section 6.5, by any Company Subsidiaries or the Company’s or the Company Subsidiaries’ respective Representatives shall be deemed to be a breach of this
Section 6.5 by the Company. 
 (b) In addition to the other obligations of the Company set forth in this Section 6.5, the
Company shall promptly advise Parent, orally and in writing (and in any case within twenty-four (24) hours of knowledge of receipt) of the receipt by the Company of any Company Takeover Proposal, or any inquiry that would reasonably be expected to
lead to any Company Takeover Proposal, or any request for information relating to the Company or any Company Subsidiaries or for access to the business, properties, assets, books or records of the Company or any Company Subsidiary by any third party
with respect to a Company Takeover Proposal. The Company shall, in any such notice to Parent, indicate the identity of the Person making such Company Takeover Proposal, indication or request, and the terms and conditions of such Company
Takeover Proposal, indication or request (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such Company Takeover Proposal, indication or request), and thereafter shall promptly
keep Parent reasonably informed, in a prompt manner, of all material developments affecting the status and terms of any such Company Takeover Proposal, indication or request or any changes to the terms thereof (and the Company shall provide Parent
promptly after receipt or delivery thereof with 

  
 54 

 
copies of any additional written materials received that relate to such Company Takeover Proposal, indication or request or any changes to the terms thereof) and of the status of any such
discussions or negotiations. In addition, during the period from the date hereof through the Effective Time, the Company shall enforce, and not terminate, amend, modify or waive (except for waiver of any standstill provisions to allow such
counterparty to make a proposal to the Company Board) any provision of any confidentiality or standstill agreement to which the Company or any Company Subsidiary is a party. 

(c) Except as expressly permitted by this Section 6.5, neither the Company Board nor any committee thereof shall (i)(A) withdraw or
modify, or propose publicly to withdraw or modify, in a manner adverse to Parent or Merger Sub, the Company Recommendation, (B) approve, recommend or declare advisable, or propose publicly to approve, recommend or declare advisable, any Company
Takeover Proposal, (C) take any action or make any public statement that is inconsistent with the Company Recommendation (other than any action taken or statement made following expiration of the Notice Period in connection with a Superior Proposal
as to which the Company has complied with Section 6.5(e) and made each determination referred to in clauses (i)(A) and (i)(B)(2) of Section 6.5(d)), (D) take any formal action or make any
recommendation or public statement in connection with a tender offer or any exchange offer from any third party, other than (1) a recommendation against such offer, (2) a position contemplated by Rule 14e-2(a) under the Exchange Act or making a
statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 under the Exchange Act or (3) a customary “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, or (E) fail to include
the Company Recommendation in the Schedule 14D-9 (any action described in this clause (i) a “Company Adverse Recommendation Change”) or (ii) approve or recommend, or propose publicly to approve or recommend, or cause or
authorize the Company or any Company Subsidiary to enter into, any letter of intent, agreement in principle, memorandum of understanding, merger, acquisition, purchase or joint venture agreement or other agreement constituting or related to, or that
is intended to or reasonably expected to lead to, any Company Takeover Proposal (other than a confidentiality agreement in accordance with Section 6.5(a)) (each, a “Company Acquisition Agreement”). 

(d) Notwithstanding anything to the contrary contained herein, but subject to Section 6.5(e), prior to, but not after, the Offer
Closing Date, the Company Board may (i) make a Company Adverse Recommendation Change, if both (A) the Company Board determines in its good faith judgment (after consultation with outside counsel) that failure to take such actions would constitute a
breach of the Company Board’s fiduciary duties to the Company’s stockholders under applicable Law and (B) the Company Board (1) receives after the date hereof but before the Offer Closing Date an unsolicited, bona fide written Company
Takeover Proposal that did not result from or arise in connection with a breach of this Section 6.5 and (2) determines in its good faith judgment (after consultation with outside counsel and a financial advisor of nationally recognized
reputation) that such Company Takeover Proposal constitutes a Superior Proposal and authorizes the Company to enter into a Company Acquisition Agreement with respect to such Superior Proposal and (ii) following or concurrently with making a Company
Adverse Recommendation Change in accordance with clause (i) of this Section 6.5(d) and Section 6.5(e), authorize the Company to terminate this Agreement if, concurrently with entering into such Company Acquisition Agreement, the
Company terminates this Agreement pursuant to Section 8.1(d)(ii) and pays the Termination Fee required pursuant to Section 8.3. 

  
 55 

 (e) The Company Board shall not make a Company Adverse Recommendation Change pursuant to
Section 6.5(d) unless (i) the Company promptly provides written notice to Parent at least three (3) Business Days before taking such action (the “Notice Period”) advising Parent that the Company Board is considering
making a Company Adverse Recommendation Change, which notice shall specify the material terms of the applicable Company Takeover Proposal, identify the Person making such Superior Proposal and include copies of any written materials relating to such
Company Takeover Proposal (the “Company Notice of Adverse Recommendation”) and (ii) during the Notice Period, the Company and its Representatives shall have, if requested by Parent, negotiated in good faith with Parent and
Parent’s Representatives to make such adjustments in the terms of this Agreement as would enable Parent to proceed with the Transactions on such adjusted terms and, at the end of such Notice Period, after taking into account any such adjusted
terms as may have been proposed by Parent since its receipt of such written notice, the Company Board shall have again in good faith made each determination referred to in clauses (i)(A) and (i)(B)(2) of Section 6.5(d). To
the extent the Notice Period described in the preceding sentence would expire after the Offer Closing Date, the Offer Closing Date shall be automatically extended such that it will occur on the first Business Day after the expiration of the Notice
Period. In the event of any material change (including, for the avoidance of doubt, any change in price) to the terms of a Superior Proposal, the Company shall, in each case, make each determination referred to in clauses (i)(A) and
(i)(B)(2) of Section 6.5(d), deliver a new Company Notice of Adverse Recommendation and commence a new Notice Period except that the duration of the Notice Period shall be reduced to 48 hours (rather than three (3) Business Days). 

(f) For purposes of this Agreement: 

“Company Takeover Proposal” means any inquiry, proposal or offer (whether in writing or otherwise) from any Person or
“group” (as defined in Section 13(d) of the Exchange Act), other than Parent and its Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of the
Company or any of the Company Subsidiaries (including securities of the Company Subsidiaries) equal to more than 15% of the Company’s consolidated assets or to which more than 15% of the Company’s revenues or earnings on a consolidated
basis are attributable, (B) direct or indirect acquisition (whether in a single transaction or a series of related transactions or by merger, consolidation or otherwise) of more than 15% of any class of equity securities of the Company or any
Company Subsidiaries or (C) tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning more than 15% of any class of equity securities of
the Company or any Company Subsidiaries or of any resulting parent company of the Company, other than the Transactions. 

“Superior Proposal” means a bona fide written Company Takeover Proposal (substituting references to “15%”
therein with “50%”) that did not arise from a breach of this Section 6.5, is obtained after the date hereof but prior to the Offer Closing Date, with no financing contingency and that the Company Board determines in its good faith
judgment (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be (a) more favorable to the stockholders of the Company from a financial point of view than the Offer and the Merger, taking into
account all relevant factors (including all the terms and conditions of such proposal and the Offer, the Merger and this Agreement (including any 

  
 56 

 
changes to the terms of the Offer, the Merger and this Agreement proposed by Parent in accordance with Section 6.5(e))) and (b) reasonably capable of being completed in accordance with its
terms, taking into account all financial, regulatory, legal and other aspects and terms of such proposal and the third party.

stockholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A under the Exchange Act or making any disclosure to its stockholders required pursuant to the rules and regulations of the SEC if the Company Board
determines (after consultation with outside legal counsel) that failure to take such actions would constitute a breach of the Company Board’s fiduciary duties to the Company’s stockholders under applicable Law. Nothing in this Agreement
shall prohibit the accurate disclosure of factual information (and such disclosure shall not be deemed to be a Company Adverse Recommendation Change) regarding (x) the business, financial condition or results of operations of the Company or (y) the
fact that a Company Takeover Proposal has been made, the identity of the party making such proposal or the material terms of such proposal to the extent, in the case of each of clauses (x) and (y), (1) the Company in good faith determines (after
consultation with outside legal counsel) that such information, facts, identity and/or terms is required to be disclosed under applicable Law and (2) any such disclosure includes the Company Recommendation without disclosing or effecting a Company
Adverse Recommendation Change. 
 Section 6.6 Stockholder Litigation. The Company shall give Parent the opportunity to participate
(at Parent’s expense) in the defense or settlement of any stockholder Litigation against the Company and its directors relating to the any of the Transactions; provided, however, that no such settlement shall be agreed to without
Parent’s prior written consent. 
 Section 6.7 Indemnification; Director and Officer Insurance. For not less than six (6)
years from and after the Effective Time, Parent agrees to, and to cause the Surviving Corporation to, (a) indemnify and hold harmless all past and present directors, officers and employees of the Company to the same extent such Persons are

for acts or omissions occurring at or prior to the Effective Time and (b) advance expenses as incurred to the extent provided for under the Company Certificate of Incorporation and Company Bylaws and such indemnification agreements; provided,
however, that Parent agrees to, and to cause the Surviving Corporation to, indemnify and hold harmless such Persons to the fullest extent permitted by Law for acts or omissions occurring in connection with the approval of this Agreement and the
consummation of any of the Transactions. Parent shall cause the Surviving Corporation to provide, for an aggregate period of not less than six (6) years from and after the Effective Time, the Company’s current and former directors and officers
an insurance policy that provides coverage for events occurring at or prior to the Effective Time (the “D&O Insurance”) that is no less favorable than the Company’s existing policy or, if

  
 57 

 
substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Corporation shall not be required to pay an annual premium for the
D&O Insurance in excess of 200% of the last annual premium paid prior to the date hereof; provided, further, that the Company has the right to incept such tail coverage prior to the Effective Time for a premium not to exceed 200% of the
last annual premium paid prior to the date hereof. If the Surviving Corporation or Parent, or any of their successors or assigns, shall (i) be liquidated and dissolved, (ii) consolidate with or merge into any other Person and shall not be the
continuing or surviving entity of such consolidation or merger or (iii) sell or otherwise transfer all or a majority of its assets to any other Person, proper provisions shall be made so that the continuing or surviving entity or Parent, as
applicable, and its successors and assigns shall assume the obligations set forth in this Section 6.7. The provisions of this Section 6.7 shall survive the Effective Time, shall thereafter not be terminated or amended in any
manner so as to adversely affect (in any material respect) any indemnified party described in this Section 6.7, are intended to be for the benefit of, and shall be enforceable by, each indemnified party described in this Section 6.7
and his or her heirs and Representatives and are in addition to, and not in substitute for, any other rights that any such person may have by Contract or otherwise. 

Section 6.8 Public Announcements. The parties agree that the initial press release(s) to be issued with respect to the
Transactions shall be in the form(s) agreed to by the parties. Except with respect to any Company Takeover Proposal or any Company Adverse Recommendation Change made in accordance with the terms of this Agreement, Parent and Merger Sub, on the
one hand, and the Company, on the other hand, shall, to the extent reasonably practicable, consult with each other before making, and give each other a reasonable opportunity to review and comment upon, any press release or other public statements
(including broad-based employee communications) with respect to this Agreement and the Transactions, and shall not issue any such press release or make any such public statement prior to such reasonably practicable consultation, except as may be
required by applicable Law, NASDAQ, the New York Stock Exchange or court process, in which case the party required to make the release or announcement shall use its commercially reasonable efforts to allow each other party reasonable time to comment
on such release or announcement in advance of such issuance. 
 Section 6.9 Employees. 

(a) For a period of 1 year following the Offer Closing, Parent shall or shall cause the Surviving Corporation to provide the employees of the
Company and the Company Subsidiaries who are employed immediately prior to the Effective Time (the “Covered Employees”) who remain employed during such period by Parent or the Surviving Corporation with, in the aggregate, a
base salary or base wage and annual cash bonus opportunities that are no less than that provided by the Company and the Company Subsidiaries; provided, however neither Parent nor Surviving Corporation shall be required to provide any equity based
compensation or any other type of compensation or benefit. Parent shall have no obligation and the Company shall take no action that would have the effect of requiring Parent or the Surviving Corporation to continue any specific plans or to
continue the employment of any specific Person. 
 (b) For purposes of determining eligibility to participate in, and non-forfeitable rights
under any employee benefit plan or arrangement of Parent or the Surviving Corporation or any of their respective Subsidiaries (including for purposes of vacation

eligibility), but not for purposes of benefit accrual under any defined benefit pension plan of Parent or any of its Subsidiaries, Covered Employees shall receive service credit for service with
the Company (and with any predecessor or acquired entities or any other entities for which the Company granted service credit) as if such service had been completed with Parent; provided, however, that such service need not be recognized to the
extent that such recognition would result in any duplication of benefits for the same period of service. As of the Effective Time, Parent or Surviving Corporation or any of their relevant Subsidiaries shall credit to Covered Employees who remain
employed after the Effective Time the amount of vacation time or paid time off that such employees had accrued under any applicable Company Benefit Plan as of immediately prior to the Effective Time. 

(c) To the extent applicable, Parent shall or shall cause the Surviving Corporation and any of their respective Subsidiaries to waive, or use
reasonable best efforts to cause its insurance carriers to waive, any pre-existing condition limitation on participation and coverage applicable to any Covered Employee or any of his or her covered dependents under any health or welfare plan of
Parent or the Surviving Corporation or any of their respective Subsidiaries (a “New Plan”) in which such Covered Employee or covered dependent shall become eligible to participate after the Effective Time to the extent such
Covered Employee or covered dependent was no longer subject to such pre-existing condition limitation under the corresponding Company Benefit Plan in which such Covered Employee or such covered dependent was participating immediately before he or
she became eligible to participate in the New Plan. Parent shall or shall cause the Surviving Corporation or the relevant Subsidiary of either to provide each Covered Employee with credit for any co-payments and deductibles paid prior to the
Effective Time and during the calendar year in which the Effective Time occurs under any Company Benefit Plan in satisfying any applicable co-payment and deductible requirements for such calendar year under any New Plan in which such Covered
Employee participates after the Effective Time. 
 (d) If requested by Parent prior to the Closing Date, the Company shall terminate, or
cause to the have terminated, the Company’s 401(k) as of the date immediately preceding the Closing Date. All resolutions and other documents issued, adopted or executed in connection with such termination shall be subject to Parent’s
reasonable prior review and comment. Parent shall take all steps necessary to permit each such Covered Employee who has received an eligible rollover distribution (as defined in Section 402(c)(4) of the Code) from the Company’s 401(k) and
profit sharing plan to roll such eligible rollover distribution, including, for a reasonable period of time following the Effective Time, any associated loans into an account under a 401(k) plan maintained by Parent or its Subsidiaries. 

(e) In the event Parent or the Surviving Corporation terminates any employee plan that is a Section 125 plan or Section 129 Plan, Surviving
Corporation shall transfer and Parent shall accept the account elections and accounts of the Covered Employees. 
 (f) Parent shall be
solely responsible for all termination and severance benefits, costs, charges and liabilities of any nature incurred with respect to the termination of any Covered Employees after the Effective Time, including any claims arising out of or relating
to any mass layoff or similar event under applicable Law occurring on or after the Effective Time. 

  
 59 

 (g) No provision of this Section 6.9 shall (i) confer any rights or remedies of any kind
or description upon any Covered Employee or any other Person other than the Company and Parent and their respective successors and assigns, (ii) be construed as an amendment, waiver or creation of or limitation on the ability to terminate any
Company Benefit Plan or benefit plan or agreement of Parent (including any New Plan) or (iii) limit the ability of the Parent, the Company, the Surviving Corporation or any of their respective Subsidiaries to terminate the employment of any Covered
Employee at any time. 
 (h) Rule 14d-10 Matters. Notwithstanding anything in this Agreement to the contrary, the Company will not,
on or after the date hereof and prior to the Offer Closing, enter into, establish, amend or modify any plan, program, agreement or arrangement pursuant to which compensation is paid or payable, or pursuant to which benefits are provided, in each
case to any former, current or future director, officer, employee, consultant, advisor or independent contractor of the Company or any Company Subsidiary (or any Person who would have assumed such role or performed such duties but for a requirement
to refrain from assuming such role or performing such duties in such plan, program, agreement or arrangement) unless, prior to such entry into, establishment, amendment or modification, the compensation committee of the Company Board (each member of
which shall be an “independent director” in accordance with the requirements of Rule 14d-10(d)(2) under the Exchange Act at the time of any such action) shall have taken all such steps as may be necessary to (i) approve as an employment
compensation, severance or other employee benefit arrangement each such plan, program, agreement or arrangement and (ii) satisfy the requirements of the non-exclusive safe harbor under Rule 14d-10(d)(2) under the Exchange Act with respect to such
plan, program, agreement or arrangement. The Company shall, prior to the Offer Closing, take such actions necessary and appropriate to ratify, confirm and approve, in accordance with and for the purpose of Rule 14d-10 under the Exchange Act,

 Section 6.11 Takeover Statutes. The
Company and the Company Board shall take all actions necessary so that the restrictions of the Takeover Statutes shall remain inapplicable to any and all of the Transactions. If any Takeover Statute becomes applicable to any of the
Transactions, the Company and the Company Board shall grant such approvals and take such actions as are necessary so that any such Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise
act to eliminate or minimize the effects of such Takeover Statute on such Transactions.

 Section
6.15 Nonregistrable CVRs. Parent and the Company shall cooperate, including by making changes to the form of CVR Agreement attached hereto as Exhibit B, as necessary to ensure that the CVRs are not subject to registration under

TERMINATION 

Section 8.1 Termination. This Agreement may be terminated and the Transactions may be abandoned at any time prior to the Effective
Time: 
 (a) by mutual written consent of Parent and the Company; 

(b) by either the Parent or the Company (by written notice to the other specifying the applicable provision or provisions hereof pursuant to
which such termination is effected): 
 (i) if the Offer Closing shall not have occurred by September 30, 2016 (the “Outside
Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(i) shall not be available to any party whose failure to perform any of its obligations under this
Agreement has been the cause of, or resulted in, the failure of the Offer Closing to have occurred on or by such date; 
 (ii) if any Law
or Order having any of the effects set forth in Section 7.1(a) shall be in effect and shall have become final and nonappealable; provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(ii)
shall not be available to any party if the Order was primarily due to the failure of such party to perform any of its obligations under this Agreement. 

(c) by Parent (by written notice to the Company specifying the applicable provision or provisions hereof pursuant to which such termination is
effected): 
 (i) at any time prior to the Offer Closing, upon a Company Adverse Recommendation Change (whether or not in compliance with
Section 6.5); 
 (ii) if, prior to the Offer Closing, the Company shall have breached or failed to perform any of its
representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (A) has resulted in or would reasonably be expected to result in to the failure of a condition set forth in clauses (iv) or
(v) of Exhibit A to be satisfied and (B) is not curable or has not been cured before the earlier of the Outside Date or twenty (20) Business Days following the date the Company receives written notice of such breach or failure to perform;

 (iii) if, at any time other than during a Notice Period, the Company Board fails to reaffirm publicly the Company Recommendation within
five (5) Business Days of Parent’s written request for such reaffirmation (or if the Outside Date is less than five (5) Business Days from the receipt of such request from Parent, by the close of business on the penultimate Business Day
preceding the Outside Date); 
 (iv) if, prior to the Offer Closing, the Company shall have materially breached any of the provisions of
Section 6.5; or 

  
 62 

 (v) if, at or prior to the Expiration Time, Parent is not required to extend the Offer pursuant
to this Agreement and any of the conditions set forth in Exhibit A shall not have been satisfied. 
 (d) by the Company (by written
notice to Parent specifying the applicable provision or provisions hereof pursuant to which such termination is effected): 
 (i) if, prior
to the Offer Closing, Parent or Merger Sub shall have breached in any material respect any of its representations or warranties or failed to perform in any material respect any of its covenants or other agreements contained in this Agreement, which
breach or failure to perform (A) has prevented or materially delayed, or would reasonably be expected to prevent or materially delay, the consummation by Parent or Merger Sub of the Transactions and (B) is not curable or has not been cured before
the earlier of the Outside Date or twenty (20) Business Days following the date Parent receives written notice of such breach or failure to perform; 

(ii) at any time prior to the Offer Closing, to accept and enter into a definitive written agreement with respect to a Superior Proposal (it
being understood that the Company shall enter into such definitive agreement simultaneously with such termination of this Agreement); provided that no termination of this Agreement pursuant to this subsection (d)(ii) shall be effective
unless the Company shall have complied with the provisions of Section 6.5 (other than an inadvertent and immaterial failure to comply with clauses (i) through (iv) of Section 6.5(a) where the failure to comply did not
directly or indirectly result in or arise in connection with a Company Takeover Proposal that the Board determined constitutes or would reasonably be expected to lead to a Superior Proposal) and the Company shall have paid the Termination Fee and
otherwise complied with its obligations under Section 8.3(b); or 
 (iii) if Merger Sub fails to consummate the Offer in accordance
with the terms of the Offer and this Agreement; provided, however, that the reason for Merger Sub’s failure to consummate the Offer is not proximately caused by the Company’s breach of this Agreement. 

Section 8.2 Effect of Termination. In the event of the termination of this Agreement by either Parent or the Company pursuant to
Section 8.1, this Agreement shall forthwith be terminated and have no further effect, the obligations of the parties hereunder shall terminate, and there shall be no liability on the part of any party hereto with respect thereto, except that
(i) the last sentence of Section 6.2, the second sentence of Section 6.8, this Section 8.2, Section 8.3 and Article IX shall survive the termination of this Agreement and (ii) nothing herein shall relieve any party
from liability or damages for fraud, any willful breach or any willful misrepresentation. For the avoidance of doubt, nothing in this Agreement (including this Section 8.2 and Section 8.3) shall relieve the Company from its
obligations under the Promissory Note issued by the Company to Parent on September 28, 2015, as amended and restated from time to time, which the Company shall promptly repay and discharge in full in accordance with its terms upon termination of
this Agreement by either party for any reason.

 Section 8.3 Fees and Expenses 

(a) Except as provided in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Transactions shall
be paid by the party incurring such fees or expenses, whether or not any of the Transactions are consummated. 
 (b) In the event that: 

 

	 	(A)	(1) prior to the Offer Closing, a Company Takeover Proposal shall have been made to the Company and such Company Takeover Proposal becomes publicly known prior to the Offer Closing or shall have been made directly to
the stockholders of the Company generally prior to the Offer Closing or any Person shall have publicly announced an intention (whether or not conditional) to make a Company Takeover Proposal, (2) thereafter this Agreement is terminated by Parent or
the Company pursuant to Section 8.1(b)(i) or by Parent pursuant to Section 8.1(c)(ii) or Section 8.1(c)(v) and (3) within twelve (12) months after such termination, the Company enters into a definitive agreement to consummate a
Company Takeover Proposal or consummates a Company Takeover Proposal (regardless of whether such Company Takeover Proposal is the same Company Takeover Proposal referred to in clause (1)); provided, that for purposes of this Section
8.3(b)(A), the term “Company Takeover Proposal” shall have the meaning assigned to such term in Section 6.5(f), except that the references to “15%” shall be deemed to be references to “50%”;

  

	 	(B)	this Agreement is terminated by Parent pursuant to Section 8.1(c)(i) or Section 8.1(c)(iii) or Section 8.1(c)(iv); or 

 

	 	(C)	this Agreement is terminated by the Company pursuant to Section 8.1(d)(ii); 

 then the Company shall pay
Parent a fee equal to $1,000,000 (one million dollars) (the “Termination Fee”) by wire transfer of same-day funds (x) upon the earlier of the entry into a definitive agreement with respect to a Company Takeover Proposal or
the consummation of a Company Takeover Proposal in the case of a termination in connection with a termination described in clause (A), (y) within five (5) Business Days after termination in the case of a termination described in clause
(B), or (z) on the date of termination of this Agreement in the case of a termination described in clause (C); provided, that in no event shall the Company be required to pay the Termination Fee on more than one occasion. 

  
 64 

 (ii) Notwithstanding anything to the contrary in this Agreement, absent fraud or willful breach,
the parties agree that the payment of the Termination Fee shall be the sole and exclusive remedy available to Parent and Merger Sub against the Company and its Affiliates with respect to this Agreement in the event the Termination Fee becomes due
and payable under the terms of this Agreement, and, upon payment of the Termination Fee, neither the Company, nor any Company Subsidiary, shall have any further liability to Parent and Merger Sub relating to or arising out of this Agreement or the
Transactions. 
 (iii) The Company acknowledges that the agreements contained in this Section 8.3(b) are an integral part of the
Transactions, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay the amount(s) due pursuant to this Section 8.3(b), and, to obtain such payment, Parent commences a
suit which results in a judgment against the Company for the amount(s) due pursuant to this Section 8.3(b), the Company shall pay to Parent its out-of-pocket costs and expenses (including attorneys’ fees and expenses) in connection with
such suit, together with interest on such amount(s) at the U.S. prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made.

 Section 9.3 Interpretation. When a reference is made in this Agreement to an Article,
Section or Exhibit, such reference shall be to an Article or Section of, or an Exhibit to, this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement,
they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a
whole and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The
definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or
referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or
consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. References to a Person are also to its permitted successors

through any date shall mean, unless otherwise specified, from and including or through and including, respectively. The symbol “$” refers to United States Dollars. 

Section 9.4 Entire Agreement; No Third-Party Beneficiaries. This Agreement together with the CVR Agreement, the Confidentiality
Agreement, the exhibits hereto or thereto, the Company Disclosure Letter and the other documents and certificates delivered pursuant hereto, (a) constitute the entire agreement, and supersede all prior agreements and understandings, both written and
oral, among the parties with respect to the subject matter of this Agreement and (b) except for each indemnified party described in Section 6.7 with respect to the provisions of Section 6.7, is not intended to confer, nor shall it
confer, upon any Person other than the parties hereto any rights or remedies or benefits of any nature whatsoever. 
 Section 9.5
Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of Law or otherwise, by any of the parties without the prior written consent of the other
parties, except that Merger Sub may assign, in its sole discretion, any or all of its rights, interests and obligations under this Agreement to any wholly owned Subsidiary of Parent, provided, that no such assignment shall relieve Merger Sub
of any of its obligations hereunder; provided, further, that no such assignment shall be permitted if it would materially impede or delay the consummation of the Offer, the Merger or the other transactions contemplated hereby. Any assignment in
violation of the preceding sentence shall be void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns. 

Section 9.6 Amendments. Subject to compliance with applicable Law, this Agreement may be amended by the parties, by action taken

as practicable following the Offer Closing. No amendment shall be made to this Agreement after the Effective Time. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties. 

Section 9.7 Waiver; Remedies Cumulative. At any time prior to the Effective Time, any party hereto may (a) extend the time for the
performance of any of the covenants, obligations or other acts of any other party hereto or (b) waive any inaccuracy of any representations or warranties or compliance with any of the agreements, covenants or conditions of any other party or with
any conditions to its own obligations. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party by its duly authorized
officer. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights. The waiver of any such right with respect to particular facts and other
circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time. All rights and remedies existing under
this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

 3 

 “Net Commercialization Licensing Payments” means (a) upfront fees,
milestone payments, royalties or similar payments actually received from and after the Milestone Start Date by the Company or any of its Subsidiaries with respect to any Staccato-Based Marketed Product under any license, collaboration or
substantively equivalent agreement between or among the Company or any of its Subsidiaries on the one hand, and any third party on the other hand, granting to such third party a license to develop and/or commercialize and/or manufacture
and/or sell (other than, in the case of supply of Staccato-Based Marketed Product to a licensee or commercializing party or any of their respective Affiliates or sublicensees for which the sales of such licensee or commercializing party or
Affiliates or sublicensees are already included under this definition) a Staccato-Based Marketed Product, which for clarity includes any and all fees, royalties, milestones or similar payments received, after the first regulatory approval to market
or sell in any country for such Staccato-Based Marketed Products by independent third parties regardless of whether such payment is for subsequent development or commercialization, less (b) Taxes. By way of example, and without
limitation, if a Staccato-Based Marketed Product is approved in the United States (e.g., ADASUVE) and subsequently any fees, milestone payments, royalties or similar payments are payable under the applicable agreement for further development
and/or commercialization (e.g., REMS change milestones) in a country in which regulatory approval to market and sell the product has not been obtained, then any and all of those payments would constitute Net Commercialization Licensing
Payments. For clarity, amounts included in the calculation of Net Commercialization Licensing Payments shall not be counted more than once, whether in the calculation of Net Development Licensing Payments or in the calculation of any other Net
Commercialization Revenues. For clarity, if any investments made by Parent and its Affiliates (other than the Company and its Subsidiaries) in development activities of ADASUVE in the Ferrer Territory (as defined in the License Agreement) result in
milestone or other similar payments under an agreement with a third party with respect to the Ferrer Territory, then such payments shall not be included in the calculation of Net Commercialization Licensing Payments hereunder. 

“Net Commercialization Revenues” means (a) total global revenue of the Company and its Subsidiaries from and after the
Milestone Start Date with respect to all Staccato-Based Marketed Products, comprised of (i) Net Commercialization Licensing Payments received by the Company and its Subsidiaries and (ii) net revenues from sales of Staccato-Based Marketed Products
directly by the Company and its Subsidiaries, as set forth on the income statement of the Company for the applicable period, less, if any, (b) rebates, returns, charge-backs, discounts or price reductions, or credits or permitted
deductions (under any applicable license or collaboration or other similar agreements or if no such agreements are in effect, as deducted by the Company from net revenues from sales of Staccato-Based Marketed Products directly by the Company and its
Subsidiaries which amounts shall in no event exceed the average percentage of revenue accrual deduction applicable to its other products; provided that if there are no such other products, such deductions shall be taken consistent with Parent’s
general business practices with respect to comparable products, taking into account market, manufacturing and other relevant factors) in connection therewith, all as calculated in accordance with the applicable policies in effect from time to time
regarding revenue recognition. Notwithstanding the foregoing, amounts paid (i) for the manufacture or supply of any Staccato-Based Products, as between or among the Company and its Subsidiaries, on the one hand, and Parent and its Affiliates
(other than the Company and its Subsidiaries), on the other hand, or (ii) with respect to any Staccato-Based Products, in each case as between or among the Company and its 

  
 4 

 
Subsidiaries, shall be excluded from the computation of Net Commercialization Revenues. For clarity, amounts included in the Net Commercialization Licensing Payments pursuant to part (a)(i)
of this definition shall not be counted more than once in the calculation of net revenues pursuant to part (a)(ii) of this definition. 

“Net Development Licensing Payments” means (a) upfront fees, milestone payments, royalties or similar payments
actually received from and after the Milestone Start Date by the Company or any of its Subsidiaries with respect to Staccato-Based Products in Development under each license, collaboration or other substantively equivalent agreement between the
Company or any of its Subsidiaries on the one hand, and any third party on the other hand, granting to such third party a license to develop, manufacture and/or commercialize a Staccato-Based Product In Development, but only to the extent such fees,
royalties and payments are paid for the development, rather than commercialization, of the Staccato-Based Product In Development, less (b) Taxes. For clarity, upfront fees, milestone payments, royalties or similar payments actually received
with respect to a Staccato-Based Product at a time when such Staccato-Based Product is approved and marketed in one or more countries but still in development in one or more other countries shall be deemed Net Commercialization Licensing
Payments. For clarity, Net Development Licensing Payments shall not include any amounts received by the Company or any of its Subsidiaries under the applicable agreement as reimbursement for development-related costs and expenses, such as
patent prosecution, maintenance and enforcement expenses, expenses incurred in connection with supporting litigation against third parties, or additional research or development expenses. 

“Non-United States Tax Law” means any Tax Law imposed by any governmental entity other than a federal, state or local
governmental entity organized in the United States.

licensee) of the Company pursuant to that certain Collaboration, License and Supply Agreement between the Company and Grupo Ferrer Internacional, S.A. dated October 5, 2011, as such agreement is in effect as of or immediately prior to the date of

the applicable Staccato-Based Product or, if none, U.S. federal transfer pricing rules and policies (the “License Agreement”).

consistent with U.S. federal transfer pricing rules and policies.

Revenues (including Net Commercialization Licensing Payments), shall be included in the computation of Net Development Licensing Payments or Net Commercialization Revenues (including Net Commercialization Licensing Payments), as applicable,
notwithstanding the fact that they are not received or realized by the Company and its Subsidiaries. 

  
 6 

 (d) The Parties intend and agree that payments which are designated or characterized as Net
Development Licensing Payments and/or Net Commercialization Revenues (including Net Commercialization Licensing Payments) shall not in any event be counted more than once in the calculations of the Milestone Target amounts. 

(e) Nothing in this Agreement shall be deemed to restrict the Company and/or its Affiliates from transferring or assigning the Staccato
Program to a third party that is not an Affiliate of the Company or Parent, so long as such third party expressly assumes all obligations of Parent hereunder.

CONTINGENT VALUE RIGHTS 

Section 2.1 Holders of CVRs; Appointment of Rights Agent. 

(a) Pursuant to the terms of the Merger Agreement, (i) each holder of any Shares shall be entitled to one CVR for each such Share and (ii) each
holder of any 2014 Warrant that is outstanding immediately prior to the Effective Time shall be entitled to one CVR for each Share underlying such 2014 Warrant. 

  
 8 

 (b) Parent hereby appoints the Rights Agent to act as rights agent for Parent in accordance with
the express terms and conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment. 
 Section 2.2
Nontransferable. CVRs may not be sold, assigned, transferred, pledged, encumbered or disposed of in any other manner, in whole or in part, other than pursuant to a Permitted Transfer. Any attempted sale, assignment, transfer,
pledge, encumbrance or disposition of CVRs, in whole or in part, in violation of this Section 2.2 shall be void ab initio and of no effect. 

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address. 

(a) CVRs shall not be evidenced by a certificate or other instrument. 

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purposes of (i) identifying the Holders of
CVRs and (ii) registering CVRs and Permitted Transfers thereof. 
 (c) Without limiting the restriction on transferability set forth in
Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer and other requested documentation in form reasonably satisfactory to the Rights Agent, duly executed by the registered
Holder or Holders thereof, or by the duly appointed legal representative, personal representative or survivor of such Holder or Holders, setting forth in reasonable detail the circumstances relating to the transfer demonstrating that such proposed
transfer is a Permitted Transfer. Upon receipt of such written notice, the Rights Agent shall notify Parent that it has received such written notice. Upon receipt of such notice from the Rights Agent, Parent shall in good faith reasonably
determine whether the transfer is a Permitted Transfer and otherwise complies with the other terms and conditions of this Agreement, and if Parent so reasonably determines that such transfer does so comply, Parent shall instruct the Rights Agent in
writing to register the transfer of the applicable CVRs in the CVR Register. All duly transferred CVRs registered in the CVR Register shall be the valid obligations of Parent, evidencing the same right, and entitling the transferee to the same
benefits and rights under this Agreement, as those held by the transferor. No transfer of a CVR shall be valid until registered in the CVR Register in accordance with this Agreement. Any transfer or assignment of CVRs shall be without
charge (other than the cost of any transfer tax or similar tax or charge) to the applicable Holder. Parent and the Rights Agent may require the Holder proposing to make a Permitted Transfer to pay a sum sufficient to cover any stamp or other
tax or charge that is imposed in connection with any such registration of transfer. 
 (d) A Holder may make a written request to the Rights
Agent to change such Holder’s address of record in the CVR Register. Such written request must be duly executed by such Holder. Upon receipt of such written request, the Rights Agent shall promptly record the change of address in the CVR
Register.

 Section 2.4 Payment Procedures. 

(a) Milestones. As soon as reasonably practicable but in any event not more than fifteen (15) Business Days following the end of
any calendar quarter in which a Milestone Target is achieved, Parent shall cause to be delivered, through its Subsidiary Ferrer Therapeutics, Inc. or any other Subsidiary of Parent, to the Rights Agent (i) a notice (the “Milestone
Achievement Notice”) indicating that the Holders are entitled to receive the applicable Milestone Payment, (ii) setting forth the amount of the applicable Milestone Payment, and (iii) an amount in cash equal to the aggregate amount of
such Milestone Payment with respect to the CVRs held by all Holders. The Rights Agent shall promptly (and in no event later than five (5) Business Days after receipt thereof by the Rights Agent) send to each Holder at its address set forth in
the CVR Register a copy of the Milestone Achievement Notice and pay, in accordance with Section 2.4(b) and (c), to each Holder an amount in cash equal to the product of (i) the applicable Milestone Payment and (ii) the number of CVRs
held by such Holder. For the avoidance of doubt, (i) in the event that (x) the Milestone 1 Target is not achieved prior to the 5th anniversary of the Milestone Start Date, (y) the Milestone 2
Target is not achieved prior to the 10th anniversary of the Milestone Start Date and/or (z) the Milestone 3 Target or Milestone 4 Target is not achieved prior to the 15th anniversary of the Milestone Start Date, then the Holders shall have no right to receive such Milestone Payments, as applicable, with respect to their CVRs, (ii) each Milestone Payment shall be
payable no more than one time (regardless of the number of Staccato-Based Products with respect to which the specified Milestone Target occurs) and (iii) each Milestone Payment shall be payable only following the initial achievement of the
applicable Milestone Target and no amounts shall be due or payable for subsequent or repeated achievements of the same Milestone Target. Exhibit A hereto sets forth the example of a calculation of Milestone Payments, for illustrative
purposes only. 
 (b) Payments to Holders. With respect to any Milestone Payment that is payable pursuant to this Agreement, the
Rights Agent shall pay the applicable amount to each of the Holders (the amount to which each Holder is entitled to receive will be based on the number of CVRs held by such Holder as reflected on the CVR Register) by (i) check mailed to the address
of each Holder as reflected on the CVR Register as of the close of business on the last Business Day prior to such payment date or (ii) with respect to Holders that are due amounts equal to or in excess of $1,000,000 in the aggregate who have
provided Parent with wire transfer instructions in writing, the Rights Agent will make payments by wire transfer of immediately available funds to the account specified in the written instructions of Parent. Parent shall cause the Rights Agent,
on behalf of and at the expense of Parent, to mail with (or, in the case of payments made to Holders who have provided Parent with wire instructions, at the same time as) each payment made a copy of the Milestone Achievement Notice to which such
payment relates. 
 (c) Withholdings. Parent, the Company and the Rights Agent shall be entitled to deduct and withhold, or
cause to be deducted or withheld, from any amounts otherwise payable pursuant to this Agreement, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended
(the “Code”), or any provision of United States state or local Tax Law (“Taxes”). To the extent that Taxes are so withheld and paid over to or deposited with the relevant governmental entity, such
amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction, withholding and payment was made; provided that if 

  
 10 

 
any such Taxes are subsequently refunded or otherwise credited to Parent or the Company, then such amounts shall be subsequently distributed pursuant to this Agreement promptly after refund or
credit. Parent, the Company and the Rights Agent will use commercially reasonable efforts to request any necessary Tax forms, including a U.S. Internal Revenue Service Form W-9 or the appropriate
series of U.S. Internal Revenue Service Form W-8, as applicable, or any similar information from persons entitled to payment pursuant to this Agreement. 

(d) Tax Treatment of Payments. The parties intend to treat all payments made under this Agreement as an adjustment to the
consideration with respect to the CVRs, unless otherwise required by applicable law. 
 (e) Investment of Funds. The Rights
Agent shall hold any cash held by it for payment to the Holders in a custodial account, non-interest bearing account or otherwise, as reasonably directed by Parent in writing. Any interest and other income resulting from such investment shall
be treated as earned by Parent for income Tax purposes and shall promptly be paid to Parent or an Affiliate of Parent, as directed by Parent (subject to any applicable Tax withholding). Notwithstanding anything to the contrary herein, Parent
shall be responsible for providing the Rights Agent with sufficient funds to satisfy its payment obligations to Holders. 
 (f) Treatment
of Undistributed Funds. Any cash that remains undistributed to the Holders of CVRs six (6) months after such payment is due in accordance with the terms of this Agreement shall be delivered to Parent within two (2) Business Days following
expiration of such six (6) month period, and shall be held in trust by Parent in a segregated account for the benefit of the Holders. Any Holders of CVRs who have not theretofore received cash with respect to such CVRs shall thereafter look
only to Parent for payment of their claim therefor. Notwithstanding any other provisions of this Agreement, any portion of the cash provided by Parent to the Rights Agent that remains unclaimed after termination of this Agreement in accordance
with Section 6.13 (or such earlier date immediately prior to such time as such amounts would otherwise escheat to, or become property of, any governmental entity) shall, to the extent permitted by Law, become the property of Parent free and
clear of any claims or interest of any Person previously entitled thereto. 
 (g) The Rights Agent shall keep copies of this Agreement
available for inspection by the Holders during normal business hours at its office. Parent shall supply the Rights Agent from time to time with such numbers of copies of this Agreement as the Rights Agent may request. 

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest. 

(a) CVRs shall not have any voting or dividend rights, and, except as set forth in this Agreement, interest shall not accrue on any amounts
payable in respect of CVRs. 
 (b) CVRs shall not represent any equity or ownership interest in Parent, any constituent company to the
Merger or any of their respective Affiliates. 
 Section 2.6 Ability to Abandon CVRs. A Holder may at any time, at such Holder’s
option, abandon all of such Holder’s remaining rights in a CVR by transferring such 

  
 11 

 
CVR to Parent without consideration therefor. Nothing in this Agreement shall prohibit Parent or any of its Affiliates from offering to acquire or acquiring any CVRs for consideration from
the Holders, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by Parent or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Acting
Holders, Article V and Section 6.4. 
 ARTICLE III 

THE RIGHTS AGENT 

Section 3.1 Certain Duties and Responsibilities of the Rights Agent. 

(a) The Rights Agent shall not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent
such liability arises as a result of the willful misconduct, bad faith or gross negligence of the Rights Agent. 
 (b) The Acting Holders
may direct the Rights Agent to act on behalf of the Holders in enforcing any of their rights hereunder. All rights of action of any or all Holders under this Agreement may be enforced by the Rights Agent, and any action, suit or proceeding
instituted by the Rights Agent shall be brought in its name as the Rights Agent and any recovery in connection therewith shall be for the proportionate benefit of all the Holders, as their respective rights or interests may appear. 

Section 3.2 Certain Rights of the Rights Agent. 

(a) The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied
covenants or obligations shall be read into this Agreement against the Rights Agent. 
 (b) The Rights Agent may rely and shall be protected
in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties. 
 (c) The Rights Agent may engage and consult with counsel of its reasonable selection and the
written advice or opinion of such outside counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(d) Any permissive rights of the Rights Agent hereunder shall not be construed as a duty. 

(e) The Rights Agent shall not be required to give any note or surety in respect of the execution of such powers or otherwise in respect of
such powers. 
 (f) Parent agrees to indemnify the Rights Agent for, and to hold the Rights Agent harmless from and against, any loss,
liability, damage or expense (“Loss”) suffered or incurred by the Rights Agent and arising out of or in connection with the Rights Agent’s 

  
 12 

 
performance of its obligations under this Agreement, including the reasonable costs and expenses of defending the Rights Agent against any claims, charges, demands, actions or suits arising out
of or in connection with such performance, except to the extent such Loss shall have been determined by a court of competent jurisdiction to have resulted from the Rights Agent’s gross negligence, bad faith or willful misconduct. Parent’s
obligations under this Section 3.2(f) to indemnify the Rights Agent shall survive the resignation or removal of any Rights Agent and the termination of this Agreement. 

(g) In addition to the indemnification provided under Section 3.2(f), but without duplication, Parent agrees (i) to pay the fees of the
Rights Agent in connection with the Rights Agent’s performance of its obligations hereunder, as agreed upon in writing by the Rights Agent and Parent on or prior to the date of this Agreement, and (ii) to reimburse the Rights Agent promptly
upon demand for all reasonable and documented out-of-pocket expenses, including all Taxes (other than income, receipt, franchise or similar Taxes) and governmental charges, incurred by the Rights Agent in the performance of its obligations under
this Agreement. 
 Section 3.3 Resignation and Removal; Appointment of Successor. 

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent and the Holders specifying a date when such resignation
shall take effect, which notice shall be sent at least sixty (60) days prior to the date so specified. 
 (b) Parent, with the consent of
the Acting Holders (such consent not to be unreasonably withheld, conditioned or delayed), shall have the right to remove the Rights Agent at any time by specifying a date when such removal shall take effect. Notice of such removal shall be given by
Parent to the Rights Agent, which notice shall be sent at least sixty (60) days prior to the date so specified. For purposes of this clause (b), a consent shall be deemed (i) granted unless the Acting Holders submit to Parent, within ten (10)
Business Days of receipt of Parent’s notice, a response setting forth in reasonable detail how the removal of the Rights Agent would adversely impact the rights of Holders to any payments under this Agreement (including the timing of such
payments), and (ii) unreasonably withheld, conditioned and delayed if the Acting Holders condition their consent upon anything other than reasonable assurances that the removal will not adversely impact the rights of Holders to any payments under
this Agreement (including the timing of such payments). 
 (c) If the Rights Agent shall resign, be removed or become incapable of acting,
Parent shall promptly appoint a qualified successor Rights Agent which appointment shall, solely in the event that the successor Rights Agent is not a member of The Securities Transfer Association, Inc., require the consent of the Acting Holders

reasonable detail the qualifications of the proposed successor Rights Agent or its independence from Parent, and (ii) unreasonably withheld, conditioned and delayed if the Acting Holders condition their consent upon anything other than reasonable
evidence of the proposed successor Rights Agent’s qualifications and independence from Parent. 

  
 13

appointment of a successor Rights Agent by mailing written notice of such event by first-class mail, postage prepaid, to the Holders as their names and addresses appear in the CVR Register. Each notice shall include the name and address of the

appointment, execute, acknowledge and deliver to Parent and to the retiring Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and thereupon such successor Rights Agent, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the Rights Agent; provided that upon the request of Parent or the successor Rights Agent, such resigning or removed Rights Agent shall execute and deliver an
instrument transferring to such successor Rights Agent all the rights, powers and trusts of such resigning or removed Rights Agent. 

ARTICLE IV 

COVENANTS 
 Section
4.1 List of Holders. Parent shall furnish or cause to be furnished to the Rights Agent the names and addresses of the Holders within thirty (30) Business Days following the Effective Time. The CVRs shall, in the case of the holders

Agreement and in a denomination equal to the number of Shares so surrendered, and in the case of 2014 Warrants, be registered in the name and address of the holder set forth in the books and records of the Company at the Effective Time and in a
denomination computed in accordance with the terms of the Merger Agreement. 
 Section 4.2 Independent Accountant Review. Upon the
written request of the Acting Holder(s) delivered to Parent not less than forty-five (45) days in advance (such request not to be made more than once in any twelve (12) month period, it being agreed that, for the avoidance of doubt, once any Acting
Holder(s) have made such request, not only such Acting Holder(s) but all other Acting Holder(s) shall be barred from making a request hereunder until the expiration of twelve (12) months from delivery of the Final Statement in respect of the first
request), Parent shall permit the Independent Accountant, at the Acting Holders’ expense, to have access upon reasonable notice and during normal business hours to such of the records of the Company and its Affiliates as is reasonably necessary
to verify the accuracy of the Net Development Licensing Payments and the Net Commercialization Revenues (including Net Commercialization Licensing Payments). Each Person seeking to receive information from Parent in connection with an audit
shall enter into, and shall cause its accounting firm to enter 

  
 14 

 
into, a reasonable and mutually satisfactory confidentiality agreement with Parent obligating such party to retain all such financial and other information disclosed to such party in confidence
pursuant to such confidentiality agreement. The Independent Accountant shall provide Parent with a copy of all disclosures made to the Acting Holders. No later than thirty (30) days following access to such records of Parent as are
reasonably necessary to verify the accuracy of the Net Development Licensing Payments and/or Net Commercialization Revenues (including Net Commercialization Licensing Payments) (as applicable), the Independent Accountant shall deliver a written
report to Parent and the Acting Holders of its preliminary findings regarding the Net Development Licensing Payments and/or Net Commercialization Revenues (including Net Commercialization Licensing Payments) and any potentially applicable Milestone
Payments (the “Preliminary Statement”). Parent and the Acting Holders shall have thirty (30) days following receipt of the Preliminary Statement from the Independent Accountant (the “Preliminary Statement
Review Period”) to review and comment upon the Preliminary Statement. The Independent Accountant shall take into consideration in good faith any comments received from Parent or the Acting Holders during the Preliminary Statement
Review Period. No later than ten (10) Business Days after the expiration of the Preliminary Statement Review Period, the Independent Accountant shall deliver a final written report to Parent and the Acting Holders (the “Final
Statement”). If the Independent Accountant in the Final Statement concludes that the Holders are entitled to one or more Milestone Payments (and such payment has not been made by Parent), then no later than ten (10) days following its
receipt of the Final Statement, Parent shall deliver an amount in cash to the Rights Agent sufficient to pay to the Holders such Milestone Payment(s), together with interest at the “prime rate” as published in the Wall Street Journal from
time to time, from the date that the applicable Milestone Payment was due. The Final Statement shall be final, conclusive and binding on Parent and the Holders, shall be nonappealable and shall not be subject to further review, absent manifest
error. 
 Section 4.3 Efforts. From and after the Effective Time until the earlier of (i) such time as no Milestone Target may
be achieved and (ii) termination of this Agreement in accordance with Section 6.13, Parent shall act in good faith, in a manner consistent with Parent’s general business practices with respect to products of similar market potential at a
similar stage of commercial development or product life, in exercising commercially reasonable efforts to achieve the Milestone Targets, taking into account all relevant factors.

(a) Parent, at any time or from time to time, may unilaterally enter into one or more amendments hereto for any of the following purposes,

covenants and obligations of the Rights Agent herein in accordance with the provisions hereof;

 (v) any other amendment hereto which would provide any additional rights or benefits to the Holders or that does not adversely affect

 (b) Promptly after the execution by Parent of any amendment pursuant to the
provisions of this Section 5.1, Parent shall mail (or cause the Rights Agent to mail) a notice thereof by first class mail to the Holders at their addresses as set forth on the CVR Register, setting forth in general terms the substance of
such amendment. 
 Section 5.2 Amendments with Consent of Holders. 

(a) In addition to any amendments to this Agreement that may be made by Parent without the consent of any Holder or the Rights Agent pursuant
to Section 5.1, with the consent of the Holders of not less than a majority of the outstanding CVRs, whether evidenced in writing or taken at a meeting of the Holders, Parent and the Rights Agent may enter into one or more amendments hereto

materially affecting the economic benefits anticipated by the parties to this Agreement. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable Law in an acceptable manner to the end that the Transactions are fulfilled to the extent possible.

the payment of the Milestone 4 Payment and (b) the fifteenth (15th) anniversary of the Milestone Start Date; it being agreed that such termination shall not relieve any party from the discharge of
any liability that has already accrued as of such time.

 Exhibit A 

Example of Calculation of Milestone Payments 

Example 1: 
 Advisory Fee Deduction =
$2,000,000 
 Adjustment Payment= +/- $1,000,000 

Number of CVRs= 23,000,000 

Milestone 1 Target achieved 

Milestone 2 Target achieved 

Milestone 1 Payment = 

If Adjustment Payment = + $1,000,000: 

($3,000,000 – 25% × $2,000,000 - $1,000,000) / 23,000,000 = $0.06 

If Adjustment Payment = - $1,000,000: 

($3,000,000 – 25% × $2,000,000 + $1,000,000) / 23,000,000 = $0.15 

Following date of Milestone 1 Payment: 

Advisory Fee Deduction = $1,500,000 

Adjustment Payment= $0.00 

Milestone 2 Payment = 

($6,000,000 – $1,500,000) / 23,000,000 = $0.19 

Example 2: 
 Advisory Fee Deduction =
$2,000,000 
 Adjustment Payment = +/- $4,000,000 

Number of CVRs= 23,000,000 

Milestone 1 Target achieved 

Milestone 2 Target achieved 

If Adjustment Payment = + $4,000,000: 

Milestone 1 Payment = 

(Greater of ($3,000,000 – 25% × $2,000,000 - $4,000,000) and 0) / 23,000,000 = 

(Greater of -$1,750,000 and 0) / 23,000,000 = $0.00 

Following date on which Milestone 1 Payment would have been made if it were not $0.00: 

Advisory Fee Deduction = $1,500,000 + remaining Adjustment Payment = $3,000,000 

Adjustment Payment = $1,500,000 

Milestone 2 Payment = 

($6,000,000 – $3,000,000) / 23,000,000 = $0.13 

If Adjustment Payment = - $4,000,000: 

Milestone 1 Payment = 

($3,000,000 – 25% × $2,000,000 + $4,000,000) / 23,000,000 = $0.28 

Following date of Milestone 1 Payment: 

Advisory Fee Deduction = $1,500,000 

Adjustment Payment = $0.00 

Milestone 2 Payment = 

($6,000,000 – $1,500,000) / 23,000,000 = $0.19

 WHEREAS, Engine is deemed to beneficially own, in
the aggregate, 367,787 shares of Common Stock, or approximately 3.7% of the Common Stock issued and outstanding on the date hereof (such percentage as determined from time to time (subject to adjustment for stock splits, reverse stock splits, stock
dividends or distributions, stock reclassifications and other similar adjustments) being “Engine’s Ownership Percentage”); 
 WHEREAS, the
Company and Engine have engaged in various discussions and communications concerning the Company’s business, financial performance and strategic plans; and

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable

created vacancy on the Board, each with a term expiring at the 2016 Annual Meeting, to hold office until his successor is elected and qualified, subject, however, to his prior resignation,
removal from office or death, as applicable; and 
 (iii) nominate the New Appointees for election to the Board as part of the
Company’s slate of director nominees for the 2016 Annual Meeting. 
 (b) The Company agrees that it will recommend, support and solicit
proxies for the election of the New Appointees at the 2016 Annual Meeting in the same manner as for the Company’s other nominees standing for election to the Board at the 2016 Annual Meeting. The Company shall use its reasonable best efforts to
hold the 2016 Annual Meeting no later than November 15, 2016. 
 (c) If any New Appointee or any Replacement Appointee(s) thereof is
unable to serve as a director or nominee or resigns as a director prior to the expiration of the Standstill Period (as defined below) and at such time Engine’s Ownership Percentage is not less than 1% of the then outstanding Common Stock
(subject to adjustment for stock splits, reverse stock splits, stock dividends or distributions, stock reclassifications and other similar adjustments) (the “Minimum Ownership Threshold”), Engine shall have the ability to recommend
a replacement person(s) (any such person shall be referred to as a “Replacement Appointee”) for appointment to the Board (it being understood that any such Replacement Director who is appointed prior to the 2016 Annual Meeting will
be nominated and recommended for election to the Board at the 2016 Annual Meeting in accordance with Section 1(c)), each in accordance with this Section 1(c). Any Replacement Appointee must (i) qualify as “independent” of
the Company pursuant to the listing standards of the New York Stock Exchange, (ii) have the relevant business and financial experience to be a director of the Company and (iii) be independent of each member of the Engine Group. Upon the
recommendation of a Replacement Appointee by Engine, the Board and any applicable committee thereof shall vote on the appointment or nomination of such Replacement Appointee, as applicable, no later than ten (10) business days after such
recommendation; provided, however, that if the Board does not appoint such Replacement Appointee as recommended, the Parties shall continue to follow the procedures of this Section 1(c) until a Replacement Appointee is appointed
to the Board as recommended. Upon a Replacement Appointee’s appointment to the Board, the Board and all applicable committees of the Board shall take all actions necessary to appoint such Replacement Appointee to any applicable committee of the
Board of which the resigned director was a member immediately prior to such director’s resignation, subject only to such Replacement Appointee’s eligibility to serve in such capacity pursuant to applicable law and stock exchange
regulations, as they may be amended from time to time. 
 (d) During the period commencing with the date of this Agreement through the
expiration or termination of the Standstill Period, the Board and all applicable committees of the Board shall take all actions necessary (including with respect to nominations for election at the 2016 Annual Meeting) so that the size of the Board
is no more than eight (8) directors at any time, unless Engine consents in writing to enlarging the Board (which consent will not be unreasonably conditioned, withheld or delayed).

 (e) As promptly as practicable following the execution of this Agreement, the Board and all
applicable committees of the Board will take all action necessary to appoint each of the New Appointees (or any Replacement Appointee(s) thereof) to the special committee of the Board (currently comprised of six (6) directors) that has been

the 2016 Annual Meeting or at any special meeting of the Company’s shareholders called or held during the Standstill Period, (ii) submit any proposal for consideration at, or bring any other business before, the 2016 Annual Meeting or any
special meeting of the Company’s shareholders called or held during the Standstill Period, or (iii) initiate, encourage or participate in any “vote no,” “withhold” or similar campaign with respect to the 2016 Annual
Meeting or any special meeting of the Company’s shareholders called or held during the Standstill Period. Each member of the Engine Group agrees not to permit any of its Affiliates or Associates to do any of the items set forth in
Section 1(f)(i), Section 1(f)(ii) and Section1(f)(iii). Each member of the Engine Group agrees not to publicly or privately encourage or support any other shareholder of the Company to take any of the actions described in
Section 1(f)(i), Section 1(f)(ii) and Section1(f)(iii). 
 (g) At the 2016 Annual Meeting and at any special meeting of the
Company’s shareholders called or held during the Standstill Period, each member of the Engine Group agrees to, and agrees to cause its Affiliates and Associates to, appear in person or by proxy and vote all shares of Common Stock beneficially
owned by it or any of its Affiliates or Associates, as applicable, in favor of the election of each of the Company’s nominees for election to the Board.

Agreement. As used in this Agreement, the terms “Affiliate” and “Associate” will have the respective meanings set forth in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or the rules or regulations promulgated
thereunder (the “Exchange Act”), and will include all persons or entities that at any time during the term of this Agreement become Affiliates or Associates of any person or entity referred to in this Agreement. As used in this

(i) If at any time Engine’s Ownership Percentage decreases to less than the Minimum Ownership Threshold, Engine will thereafter have no

less than the Minimum Ownership Threshold. 
 (ii) Prior to the date of this Agreement, each of the New Appointees has submitted to the
Company a fully completed copy of the director and officer questionnaire and other director onboarding documentation (including an authorization form to conduct a background check) required by, and consistent with the past onboarding practices of,
the Company in connection with the appointment or election of such persons to the Board. Any Replacement Appointee will also promptly submit to the Company (A) a joinder to this Agreement executed by such Replacement Appointee pursuant to which
such Replacement Appointee will be bound by the terms of, and become a Party to, this Agreement effective upon his or her appointment or election to the Board in accordance with Section 1(c) (it being understood that any Replacement Appointee

authorization form to conduct a background check) required by the Company in connection with the appointment or election of such person to the Board. The New Appointees hereby represent and warrant that all of the information they have submitted to
the Company in such director and officer questionnaires and other director onboarding documentation is, to the best of their knowledge, true, correct and complete in all respects. 

(iii) The Engine Group shall comply with its filing and reporting obligations under Rule 13d-1 and Rule 13d-2 under the Exchange Act with

of the Company; 
 (ii) form, join or in any way participate in any “group” (within the meaning of Section 13(d)(3) of the
Exchange Act) with respect to the Common Stock (other than a “group” that includes all or some of the members of the Engine Group); provided, however, that nothing 

  
 - 4 -

such Affiliate or Associate agrees to be bound by the terms and conditions of this Agreement; 
 (iii) deposit any Common Stock in any

accordance with this Agreement; 
 (iv) seek or encourage any person to submit nominations in furtherance of a “contested
solicitation” for the election or removal of directors with respect to the Company or seek, encourage or take any other action with respect to the election or removal of any directors; provided, however, that nothing in this
Agreement shall prevent any member of the Engine Group or their respective Affiliates or Associates from taking actions in furtherance of identifying director candidates in connection with the 2017 annual meeting of shareholders of the Company so
long as such actions do not create a public disclosure obligation for any of the Parties, are undertaken on a basis reasonably designed to be confidential and are consistent with the past practices of the members of the Engine Group in such
circumstances; 
 (v) (A) make any proposal for consideration by shareholders at any annual or special meeting of the Company’s
shareholders, (B) make any offer or proposal (with or without conditions) with respect to a merger, acquisition, recapitalization, restructuring, disposition or other business combination involving the Company, or encourage, initiate or support
any third party in any such activity, (C) affirmatively solicit a third party to make an offer or proposal (with or without conditions) with respect to a merger, acquisition, recapitalization, restructuring, disposition or other business
combination involving the Company, or knowingly encourage, initiate or support any third party in any such activity or (D) make any public communication or comment in opposition to any merger, acquisition, recapitalization, restructuring,
disposition or other business combination involving the Company that has been approved by the Board;

products or services or their subsidiaries, affiliates, successors, assigns, officers (or former officers), directors (or former directors), employees, shareholders, agents, attorneys or
representatives. 
 7. Press Release. Promptly following the execution of this Agreement, the Company and the Engine Group will
jointly issue a mutually agreeable press release (the “Mutual Press Release”) announcing certain terms of this Agreement, in the form attached hereto as Exhibit B. Prior to the issuance of the Mutual Press Release, neither
the Company nor any member of the Engine Group will issue any press release or public announcement regarding this Agreement without the prior written consent of Engine (in the case of the Company) or the Company (in the case of a member of the
Engine Group). Until the 2016 Annual Meeting, none of the Company, the New Appointees, any Replacement Appointee(s) or any other member of the Engine Group will make any public announcement or statement that is inconsistent with or contrary to the
statements made in the Mutual Press Release, except as required by law or the rules of any stock exchange or with the prior written consent of Engine (in the case of the Company) or the Company (in the case of a member of the Engine Group or any of

detailed invoice evidencing the Engine Group’s reasonable, documented out-of-pocket fees and expenses (including legal expenses) incurred in connection with seeking Board representation at the Company at the 2016 Annual Meeting and the
negotiation and execution of this Agreement, shall reimburse the Engine Group for the amounts so incurred provided that such reimbursement shall not exceed $50,000 in the aggregate. 

9. Termination. This Agreement will immediately and automatically terminate and no Party shall have any further right or obligation
under this Agreement on January 1, 2017; provided, however, that Section 3, this Section 9 and Sections 10 through 16 shall survive any termination of this Agreement. 

10. Specific Performance. Each of the Parties acknowledge and agree that irreparable injury to the other Parties would occur in the
event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that such injury would not be adequately compensable by the remedies available at law (including the payment of
money damages). It is accordingly agreed that Engine, on the one hand, and the Company, on the other hand (the “Moving Party”), will each be entitled to specific enforcement of, and injunctive relief to prevent any violation of, the
terms hereof, and the other Parties will not take action, directly or indirectly, in opposition to the Moving Party seeking such relief on the grounds that any other remedy or relief is available at law or in equity. This Section 10 is not the
exclusive remedy for any violation of this Agreement. 
 11. Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement will remain in full force and effect and will in no way be affected,
impaired or invalidated. It is hereby stipulated and 

  
 - 9 - 

 
declared to be the intention of the Parties that the Parties would have executed the remaining terms, provisions, covenants and restrictions without including any of such which may be hereafter
declared invalid, void or unenforceable. In addition, the Parties agree to use their best efforts to agree upon and substitute a valid and enforceable term, provision, covenant or restriction for any of such that is held invalid, void or enforceable
by a court of competent jurisdiction.

or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (a) upon receipt, when delivered personally; (b) upon receipt, when sent by facsimile (provided confirmation of

Entire Agreement; Amendment and Waiver; Successors and Assigns; Third Party Beneficiaries. This Agreement contains the entire understanding of the Parties with respect to its subject matter. There are no restrictions, agreements, promises,
representations, warranties, covenants or undertakings between the Parties other than those expressly set forth herein. No modifications of this Agreement can be made except in writing signed by an authorized representative of each of Engine (in the
case of the Company) or the Company (in the case of a member of the Engine Group), except that the signature of an authorized representative of the Company will not be required to permit an Affiliate of any member of the Engine Group to agree to be
a member of the Engine Group. No failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder will operate as a waiver thereof, nor will any single or partial exercise of such right, power or remedy
by such Party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law. The terms and conditions of this
Agreement will be binding upon, inure to the benefit of, and be enforceable by the Parties and their respective successors, heirs, executors, legal representatives and permitted assigns. No Party will assign this Agreement or any rights or
obligations hereunder without the prior written consent of Engine (in the case of the Company) or the Company (in the case of a member of the Engine Group).
