 INTRODUCTION 
 The Owens & Minor Directors’ Deferred Compensation Plan (the Plan) is effective as of January 1, 2005. The Plan is an amendment and restatement of the Deferred Fee Program that was part of the
Owens & Minor, Inc. 2003 Directors’ Compensation Plan (the 2003 Plan). Except with respect to the Deferred Fee Program, the 2003 Plan remains effective in accordance with its terms and is not affected by the adoption of the Plan.

 The Plan governs both a Participant’s Grandfather Account, i.e., the portion of a Participant’s Account that was credited
on or before, December 31, 2004 (as adjusted for investment earnings and losses after 2004) and the Participant’s Current Account, i.e., the portion of a Participant’s Account that was credited on and after January 1, 2005
(as adjusted for investment earnings and losses). 
 The Deferred Fee Program under the 2003 Plan is amended and restated to assure
compliance with Section 409A of the Code. The Plan must be administered and interpreted so that (i) the Grandfather Accounts remain exempt from Section 409A of the Code and (ii) the requirements of Section 409A of the Code
are satisfied with respect to the Current Accounts. 
 The Plan is intended to assist the Company in promoting a greater identity of interest
between Participants and the Company and its shareholders. The Plan is also intended to assist the Company in attracting and retaining non-employee Directors by affording them an opportunity to share in the future success of the Company.

 ARTICLE III 
 DEFERRED FEE PROGRAM 
  

	3.01.	Deferral Elections 

 (a) A Participant may
make a deferral election with respect to all or a part of his or her Compensation to be earned and payable after the Election Date by completing and executing an Election Form and submitting it to the Secretary of the Company. A deferral election
relating to a Retainer Fee shall be in integral multiples of twenty-five percent (25%) of the portion of the Retainer Fee payable in cash and an integral multiple of twenty-five percent (25%) of the portion of the Retainer Fee payable as a
Stock Award. A deferral election relating to Meeting Fees shall be in integral multiples of twenty-five percent (25%) of each Meeting Fee. On or before the Election Date, an individual who is not a member of the Board may complete an Election
Form contingent upon the individual becoming a Participant in which case the Deferral Election will be effective with respect to all or part of his or her Compensation to be earned and payable on and after becoming a Participant and after the date
of the deferral election. 
 (b) In accordance with the terms of the Plan, the Participant shall indicate on the Election Form: (i) the
percentage of the Retainer Fee and the percentage of the Meeting Fee that he or she wishes to defer; (ii) the distribution date; (iii) whether distributions are to be in a lump sum, in installments or a combination thereof; (iv) his
or her Beneficiary or Beneficiaries; and (v) the Subaccounts to which the Deferred Amount is to be allocated. 
 (c) A deferral election
shall remain in effect with respect to all future Compensation until a new deferral election is made by the Participant in accordance with Section 3.01(a); provided, however, that on each Election Date a deferral election becomes irrevocable
with respect to Compensation to be earned and payable in the calendar year after the Election Date. 
  

	3.02.	Beneficiary Election Modification 

 A
Participant shall be permitted at any time to modify his or her Beneficiary designation by completing and executing a new Election Form and submitting it to the Secretary of the Company. 
  

	3.03.	Investments 

 (a) The Company shall establish
an Account (for bookkeeping purposes only), for each Participant and for each Beneficiary to whom installment distributions are being made. On each Allocation Date, the Company shall allocate to each Participant’s Account an amount equal to his
Deferred Amount. 
  

 4 

 (b) The Company shall establish within each Account one or more Subaccounts, which shall be credited with
earnings and charged with losses, if any. One Subaccount shall be the Common Stock Account. The other Subaccounts, if any, shall be designated by the Committee from time to time. 
 (c) Subject to the provisions of Sections 3.04 and 3.05, on each Allocation Date, each Participant’s Subaccount shall be credited with an amount
equal to the Deferred Amount designated by the Participant for allocation to such Subaccounts. Each Subaccount shall be credited with earnings and charged with losses as if the amounts allocated thereto actually had been invested in the investment
designated as that subaccount. 
  

	3.04.	Investment Directions 

 In connection with
his or her initial deferral election, each Participant shall make an investment direction on his or her Election Form with respect to the portion of such Participant’s Deferred Amount that is to be allocated to each Subaccount of the
Participant’s Account. Any apportionment of Deferred Amounts (and of increases or decreases in Deferred Amounts) among the Subaccounts shall be in integral multiples of ten percent (10%). An investment direction shall become effective with
respect to a Subaccount on the first day of the calendar month following the Election Date. All investment directions shall remain in effect with respect to all future Deferred Amounts until a new investment direction made by the Participant in
accordance with Section 3.05 becomes effective. 
  

	3.05.	New Investment Directions 

 A Participant may
make a new investment direction with respect to his or her Deferred Amount only by completing and executing a new Election Form and submitting it to the Secretary of the Company. A new investment direction shall become effective with respect to a
Subaccount on the first day of the calendar month following the Election Date. 
  

	3.06.	Investment Transfers 

 A Participant or a
Beneficiary (after the death of the Participant) may transfer to one or more different Subaccounts all or a part (in integral multiples of ten percent (10%)) of the amounts credited to a Subaccount by completing and executing a transfer form
and submitting it to the Secretary of the Company. Except as provided in the following sentence, any transfer of amounts among the Subaccounts shall become effective on the first day of the calendar month following the specified transfer date. With
respect to a transfer to or from the Common Stock Account of a Participant then subject to Section 16 of the Exchange Act, the transfer shall become effective on the first day of the first calendar month following the specified transfer date
that is at least six months after the Participant’s most recent “opposite way” discretionary transaction (as such term is defined in Securities and Exchange Commission Rule 16b-3). 
  

	3.07.	Distribution Elections 

 (a) A
Participant’s Grandfather Account shall be distributed on the date or the occurrence of the event as specified in one or more Election Forms as in effect on December 31, 2004. 
  

 5 

 (b) A Participant’s Current Account shall be distributed on the date or the occurrence of the event
as specified in one or more Election Forms subject to the following: 
 (1) Each Participant shall designate on his or her
Election Form a distribution date for each Deferred Amount credited to the Participant’s Current Account. Subject to clause (2) below, the distribution date may be (i) the first day of a calendar month specified by the Participant,
(ii) the first day of a calendar month following the date of termination of the Participant’s service as a member of the Board, (iii) the earlier of a specified date or termination of service on the Board or (iv) the later of a
specified date or termination of service on the Board. 
 (2) If a distribution (i) is payable upon the occurrence of a
specified date, i.e., it is not payable on account of the termination of the Participant’s service as a member of the Board and (ii) requires a cash distribution of the Participant’s interest in the Common Stock Account, the
distribution shall not be made before the first day of the calendar month that is at least six months after the Participant’s most recent “opposite way” discretionary transaction (as such term is defined in Securities and Exchange
Commission Rule 16b-3). If a distribution (i) is payable on account of the termination of the Participant’s service as a member of the Board, (ii) the Participant is a “specified employee” (as defined in Section 409A of
the Code) and (iii) the Participant’s service as a member of the Board terminated for reasons other than the Participant’s death or because the Participant is “disabled” (as defined Section 409A of the Code), the
distribution shall be made as of the first day of the seventh month beginning after the termination of the Participant’s service as a member of the Board. 
 (3) Except as provided in clause (4) below, after the applicable Election Date a Participant cannot change the distribution date
specified on his or her Election Form. 
 (4) A Participant may specify a distribution date for his or her current Account
that differs from a prior Election Form with respect to Compensation earned and payable after the Election Date on or after the new Election Form is completed. In addition, no later than December 31, 2008, a Participant may change the
distribution date for Deferred Amounts credited to his or her Current Account if the new Election Form does not require a distribution in the year in which the new election is made nor postpone to a later year a distribution that would have been
made in the year in which the new election is made. A new distribution date elected under this clause (4) must be a distribution date that satisfies clause (1) above. 
 (c) If the Distribution Date is the first day of the month following the Participant’s death or a fixed date which in fact occurs after the
Participant’s death or if at the time of death the Participant was receiving distributions in installments, the balance remaining in the Participant’s Account shall be payable to his or her Beneficiaries as set forth on the
Participant’s current Election Form or Forms. Upon the death of a Beneficiary who is receiving distributions in installments, the balance remaining in the Account of the Beneficiary shall be payable to the Beneficiary’s estate in a lump
sum. 
  

 6 

 (d) All distributions shall be paid in cash and, except as provided in Section 3.09(b)(ii), shall be
deemed to have been made from each Subaccount pro rata. Notwithstanding the preceding sentence, with the consent of the Committee a Participant or Beneficiary may elect to receive a distribution from the Common Stock Account in whole shares of
Common Stock and cash in lieu of a fractional share. Shares of Common Stock may be distributed only in accordance with the terms of a plan approved by the Company’s shareholders. 
  

	3.08.	Form of Distribution 

 (a) A
Participant’s Grandfather Account shall be distributed in the form specified on one or more Election Forms as in effect on December 31, 2004. If the Grandfather Account is distributed in installments, the amount of each installment shall
be determined by dividing the Grandfather Account balance by the number of remaining installments. If a Participant receives a distribution from a Grandfather Account on an installment basis, amounts remaining in the Grandfather Account shall
continue to accrue earnings and incur losses in accordance with the terms of Section 3.03. 
 (b) A Participant’s Current Account
shall be distributed in the form specified on one or more Election Forms subject to the following: 
 (1) Each Participant
shall designate on his or her Election Form the manner in which each Deferred Amount credited to the Participant’s Current Account will be paid. A Participant’s Election Form may specify that distributions from his or her Current Account
shall be paid (i) in a lump sum, (ii) no more than one hundred eighty (180) monthly installments, (iii) no more than sixty (60) quarterly installments or (iv) no more than fifteen (15) annual installments. Each
installment shall be determined by dividing the Current Account balance by the number of remaining installments. If a Participant receives a distribution from his or her Current Account on an installment basis, amounts remaining in the Current
Account shall continue to accrue earnings and incur losses in accordance with the terms of Section 3.03. 
 (2) Except as
provided in clause (3) below, after the applicable Election Date a Participant may not change the form of distribution specified on his or her Election Form for his or her Current Account. 
 (3) A Participant may specify a distribution form for his or her Current Account that differs from a prior Election Form with respect to
Compensation earned and payable after the Election Date on or after the new Election Form is completed. In addition, no later than December 31, 2008, a Participant may change the form of distribution for Deferred Amounts credited to his or her
Current Account if the new Election Form does not relate to an amount to be distributed in the year in which the new election is made or an amount that would have been distributed in that year but for the new Election Form. A new distribution form
elected under this clause (3) must specify a form of payment that satisfies clause (1) above. 
  

 7 

	3.09.	Extraordinary Distributions 

 (a)
Notwithstanding the foregoing, a Participant may request an extraordinary distribution of all or part of the amount credited to his or her Account on account of an “unforeseeable emergency” (as defined in Section 409A of the Code).

 (b) A request for an extraordinary distribution shall be made by completing and executing an Extraordinary Distribution Request Form and
submitting it to the Secretary of the Company. All extraordinary distributions shall be subject to approval by the Committee. The Extraordinary Distribution Request Form shall indicate: (i) the amount to be distributed from the Account;
(ii) the Subaccount(s) from which the distribution is to be made; and (iii) the “unforeseeable emergency” requiring the distribution. The amount of any extraordinary distribution shall not exceed the lesser of the amount
determined by the Committee to be required to meet the immediate financial need of the applicant or the amount credited to the Participant’s Account. 
 (c) An extraordinary distribution shall be made with respect to amounts credited to any of the Subaccounts, if the recipient is not then subject to Section 16 of the Exchange Act, on the first day of the calendar
month next following approval of the extraordinary distribution request by the Committee. An extraordinary distribution requested by a Participant who is then subject to Section 16 of the Exchange Act shall commence with respect to amounts
credited to the Common Stock Account on the first day of the first calendar month that is at least six months following the Participant’s most recent “opposite way” discretionary transaction (as such term is defined in Securities and
Exchange Commission Rule 16b-3) or, if later, the first day of the calendar month next following approval of the extraordinary distribution request by the Committee. 
  

	3.10.	Termination of Service; Specified Employees 

 (a) As used in this Plan, the phrase “termination of service on the Board” and similar language means a separation from service as contemplated by Treasury Regulation Section 1.409A-1(h). 
 (b) If a Participant is a “specified employee,” a distribution that is payable on account of the Participant’s termination of service on
the Board shall not be made before the date that is six months after the termination of service. The preceding sentence shall not apply, and the distribution shall not be postponed if the termination of service is on account of the
Participant’s death or because the Participant is disabled within the meaning of Section 409A of the Code. The term “specified employee” has the meaning set forth in Treasury Regulation Section 1.409A-1(i) (based on a
“specified employee identification date” of December 31 and a “specified employee effective date” of the following April 1). 
 ARTICLE IV 
 SHAREHOLDER RIGHTS 
 No Participant shall have any rights as a shareholder with respect to his or her participation in the Plan unless and until the Participant receives a
distribution of Common Stock from his or her Common Stock Account. 
  

 8 

 ARTICLE V 
 ADJUSTMENT UPON CHANGE IN COMMON STOCK 
 The records of the Company Stock Account shall be
adjusted, as the Committee shall determine to be equitably required in the event that (a) the Company (i) effects one or more stock dividends, stock split-ups, subdivisions or consolidations of shares or (ii) engages in a transaction
to which Section 424 of the Code applies or (b) there occurs any other event which, in the judgment of the Committee necessitates such action. Any determination made under this Article V by the Committee shall be final and conclusive.

 The issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or
property, or for labor or services, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not
affect, and no adjustment by reason thereof shall be made with respect to, the records of the Company Stock Account. 
 ARTICLE VI 

 COMPLIANCE WITH LAW, ETC. 
 No Common Stock shall be issued, no certificates for shares of Common Stock shall be delivered, and no payment shall be made under this Plan except in compliance with all applicable federal and state laws and
regulations, any listing agreement to which the Company is a party, and the rules of all domestic stock exchanges on which the Company’s shares may be listed. The Company shall have the right to rely on an opinion of its counsel as to such
compliance. No Common Stock shall be issued, no certificate for shares shall be delivered, and no payment shall be made under this Plan until the Company has obtained such consent or approval as the Committee may deem advisable from regulatory
bodies having jurisdiction over such matters. 
 ARTICLE VII 
 GENERAL PROVISIONS 
  

	7.01.	Unfunded Plan 

 The Plan shall be unfunded,
and the Company shall not be required to segregate any assets that may at any time be represented by grants under, or participation in, this Plan. Any liability of the Company to any person with respect to any grant under, or participation in, this
Plan shall be based solely upon any contractual obligations that may be created pursuant to this Plan. No such obligation of the Company shall be deemed to be secured by any pledge of, or other encumbrance on, any property of the Company.

  

	7.02.	Rules of Construction 

 Headings are given to
the articles and sections of this Plan solely as a convenience to facilitate reference. The use of the singular includes the plural and the reference to one gender includes the other. The reference to any statute, regulation, or other provision of
law shall be construed to refer to any amendment to or successor of such provision of law. 
  

 9 

	7.03.	Nontransferability 

 A Participant may not
transfer or assign any rights that he or she has under this Plan other than by will or the laws of descent and distribution. No right or interest of any Participant or Beneficiary under the Plan shall be liable for, or subject to, any lien,
obligation or liability of such Participant or Beneficiary. 
 ARTICLE VIII 
 AMENDMENT AND TERMINATION 
 The Board may amend or terminate this Plan
from time to time; provided, however, that no amendment may become effective until shareholder approval is obtained if approval of the Company’s shareholders is required by applicable law or the rules of any stock exchange on which the Common
Stock is listed for trading. No amendment shall, without a Participant’s consent, adversely affect any rights of such Participant under the Plan as in effect at the time such amendment is made. No amendment or termination of the Plan may cause
a distribution of Plan benefits that does not satisfy requirements of Sections 409A of the Code. 
 ARTICLE IX 
 DURATION OF PLAN 
 The Plan
shall remain in effect as to amounts deferred before that date until all Participants’ Accounts have been distributed in full, unless sooner terminated by the Board.

 NOTE AND WARRANT PURCHASE AGREEMENT 
 This Note and Warrant Purchase Agreement (this “Agreement”) dated as of October 31, 2008 is made by and between GTC
Biotherapeutics, Inc., a Massachusetts corporation, (the “Company”), and LFB Biotechnologies, a société par actions simplifiée unipersonnelle established under the laws of France (the
“Purchaser”). 
 RECITALS 
 A. In accordance with the terms and conditions of this Agreement and pursuant to exemptions from registration under the Securities Act of 1933 (as amended from time to time, the “Securities Act”),
which may include without limitation the exemption afforded by Regulation S promulgated thereunder, the Company has agreed to issue and sell, and the Purchaser has agreed to purchase (i) a convertible note with a principal amount of
$15,000,000, which note shall be convertible in accordance with the terms thereof into shares of common stock, par value $0.01 per share (the “Common Stock”), of the Company and (ii) a warrant, which warrant shall be
exercisable in accordance with the terms thereof for shares of Common Stock. 
 NOW THEREFORE, in consideration of the promises and the
mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Purchaser hereby agree as follows: 
 1. PURCHASE AND SALE 
 (a) Purchase of
Note and Warrant. At the Closing (as defined in Section 3(a)), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, upon the terms and subject to the conditions set forth herein, (i) a
secured subordinated convertible note of the Company in the original principal amount of $15,000,000, which note shall be in the form attached hereto as Exhibit A (the “Convertible Note”) and (ii) a warrant to purchase
up to 23,193,548 shares of Common Stock at an exercise price of $0.31 per share, which warrant shall be in the form attached hereto as Exhibit B (the “Warrant”). 
 2. SHAREHOLDER APPROVAL 
 As soon as
practicable following the execution of this Agreement, but in any event within 30 calendar days thereof, provided that the Company received the consent of General Electric Capital Corporation (“GE Capital”), pursuant to the Amended
and Restated Master Security Agreement dated December 29, 2006, with respect to the transactions contemplated herein, the Company shall cause to be prepared and filed with the Securities and Exchange Commission (the “SEC”) a
preliminary proxy statement or consent solicitation statement (the “Preliminary Proxy Statement”) to obtain approval of the Company’s shareholders of (i) the issuance of shares of Common Stock issuable upon conversion of
the Convertible Note and exercise of the Warrant, (ii) an increase in the number of shares of Common Stock available for issuance under the Company’s Amended and Restated 2002 Equity Incentive Plan by 2,000,0001 shares and (iii) an amendment of the Company’s articles of organization to increase the number of authorized 
  

	1	Includes 1,000,000 shares of Common Stock that have been excluded from the Warrant to be issued to Purchaser under this Agreement. 

 
shares of Common Stock to 210,000,000 shares, but with respect to this clause (iii), only if the Company has not declared prior to final adjournment of the
related shareholder meeting a reverse stock split (the “Reverse Stock Split”) pursuant to the authority previously granted by shareholders at the Company’s 2008 annual meeting of shareholders (collectively, the
“Shareholder Approval”). If the Company has not obtained the consent of GE Capital within 30 days after the date of this Agreement, either party may terminate this Agreement upon notice to the other party. 
 Upon approval by the SEC of such preliminary proxy or consent solicitation statement or, if the SEC has not reviewed such, at the expiration of 10
calendar days from the filing of the preliminary proxy statement or consent solicitation statement, the Company shall file a definitive proxy statement or consent solicitation statement and call and hold a shareholder meeting within 30 calendar days
of the filing of such definitive proxy statement to obtain the Shareholder Approval. 
 If the Shareholder Approval is not received on or
before (a) January 15, 2009, if the SEC does not review the Preliminary Proxy Statement or (b) 30 calendar days after the filing of the definitive proxy statement, if the SEC reviews the Preliminary Proxy Statement (whichever date is
applicable being the “Shareholder Approval Deadline”), then the obligation of the Purchaser to purchase the Convertible Note and the Warrant shall terminate. 
 Purchaser agrees to vote all shares of Common Stock and shares of Series D Preferred Stock that it holds and is entitled to vote in favor of the
Shareholder Approval. 
 3. CLOSING 
 (a) Closing Date. If the Company receives the Shareholder Approvals on or before the Shareholder Approval Deadline, the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the Convertible
Note and the Warrant (the “Closing”) on the third Business Day following the date of receipt of Shareholder Approval, or such other date as may be mutually agreed by the Purchaser and the Company (the “Closing
Date”). Subject to the satisfaction of the closing conditions contained herein, at the Closing, the Purchaser shall pay the Company $15,000,000 (the “Purchase Price”), by wire transfer of immediately available funds in
accordance with the Company’s written wire instructions, and the Company shall deliver to the Purchaser the Convertible Note and the Warrant duly executed and completed and dated the Closing Date. 
 (b) Conditions to the Company’s Obligation. The Company’s obligation to issue and sell the Convertible Note and the Warrant shall be
subject to the satisfaction, at or before the Closing Date, of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion:

	 	(xii)	receipt of such other information, certificates and documents, including Intellectual Property Security Agreements, as the Purchaser may reasonably request.

 4. RIGHTS OF PARTICIPATION/FIRST REFUSAL 
 (a) Right to Participate. At any time after the date of this Agreement, the Purchaser shall have the right to purchase up to its then pro rata share of New Securities (as defined in Section 4(d)) which the
Company may propose to sell and issue. In the event the Company proposes to undertake an issuance of New Securities during such period, it shall give the Purchaser written notice of its intention, describing the type of New Securities, their price,
the number of New Securities to be offered, and the general terms upon which the Company proposes to issue the same. The Purchaser shall have ten (10) calendar days after any such notice is delivered to agree to purchase at the same price
(which shall be the public purchase price, if applicable) and upon the same terms, including closing date, such New Securities in an amount up to the Purchaser’s pro rata share of such New Securities. 
 (b) Right of First Refusal/Negotiation. In the event the Company proposes to undertake an issuance of New Securities after June 1, 2009, it
shall first give the Purchaser written notice of its intention, describing the type of New Securities, their proposed price, the number of New Securities to be offered, and the general terms upon which the Company proposes to issue the same. The
Purchaser shall have the right to purchase or not purchase such New Securities on the proposed terms (the “Right of First Refusal”), and if it chooses not to purchase the New Securities on the proposed terms, it shall have the right
to negotiate with Company alternative terms on which to purchase all of such New Securities (the “Right of First Negotiation”). The Purchaser shall have ten (10) calendar days after notice by the Company is delivered to either
purchase the New Securities in accordance with the Company’s proposed terms pursuant to its Right of First Refusal or to negotiate with the Company alternative terms to purchase all such New Securities pursuant to its Right of First
Negotiation. If the Purchaser timely notifies the Company of its desire to exercise its Right of First Negotiation, then the parties shall negotiate exclusively and in good faith with each other to finalize terms and definitive documentation, for a
period of up to twenty (20) days. If the Parties fail to finalize terms and execute and deliver definitive documentation in such twenty (20) day period, the Company shall have ninety (90) days thereafter to sell or enter into an
agreement to sell New Securities, at a price and upon terms, economic and otherwise, which are no more favorable to the purchasers than those offered by the Purchaser. In the event the Purchaser elects not to purchase the New Securities pursuant to
its Right of First Refusal and not to exercise its Right of First Negotiation, the Company shall have ninety (90) days thereafter to sell or enter into an agreement to sell New Securities, at a price and upon terms no more favorable to the
purchasers thereof than specified in the written notice delivered to the Purchaser pursuant to this Section 4(b). In the event the Company has not sold such New Securities or entered into an agreement to sell such New Securities within such
ninety (90) day periods, the Company shall not thereafter issue or sell any New Securities without first again complying with this Section 4(b). Notwithstanding, anything contained herein to the contrary, in the event the Purchaser does
not exercise the Right of First Refusal or exercises the Right of First Negotiation but fails to reach an 

  

 - 5 - 

 
agreement with the Company with respect to the purchase of such New Securities, the Purchaser shall have the right to purchase up to its pro rata share of
any such New Securities sold in accordance with Section 4(a) above. 
 (c) Pro Rata Share. For purposes of this Section 4,
the Purchaser’s pro rata share is equal to the ratio of (A) the number of shares of Common Stock owned by the Purchaser (including any affiliate thereof) assuming full conversion or exercise of any outstanding convertible securities
(including the Convertible Note and the Warrant), rights, options and warrants held by the Purchaser (or any affiliate thereof) into Common Stock to (B) the total number of shares of Common Stock outstanding (assuming full conversion or
exercise of any outstanding convertible securities (including the Convertible Note and the Warrant), rights, options and warrants held by the Purchaser (or any affiliate thereof) into Common Stock). 
 (d) New Securities. “New Securities” shall mean any capital stock of the Company whether now authorized or not, and rights,
convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever, including debt, that are, or may become, exercisable or convertible into capital stock; provided that the term New Securities
does not include: 
  

	 	(i)	securities issued in connection with any stock dividend, stock split, split-up or other distribution on shares of Common Stock; 

  

	 	(ii)	securities issued upon the conversion or exercise of any outstanding convertible or exercisable securities as of the date of this Agreement; 

  

	 	(iii)	securities issued upon exercise or grant of options or other equity awards with respect to shares of Common Stock, subject in either case to appropriate adjustment in the event of
any stock dividend, stock split, combination or other similar recapitalization affecting such shares, issued or issuable to employees or directors of, or consultants to, the Company pursuant to an equity plan of the Company or other arrangement
approved by the Board of Directors of the Company; 

  

	 	(iv)	securities issued or issuable pursuant to the bona fide acquisition of another corporation by the Company by merger, purchase of substantially all of the assets or other
reorganization, which acquisition is approved by a majority vote of the Board of Directors of the Company, including a majority of the Purchaser’s representatives on the Board of Directors; 

  

	 	(v)	securities issued or issuable to banks, equipment lessors or other financial institutions pursuant to a debt financing, equipment lease, bank credit arrangement or commercial
leasing transaction entered into for primarily non-equity financing purposes; 

  

	 	(vi)	securities of the Company which the Board of Directors of the Company unanimously determines shall be excluded from the definition of New Securities; and 

 

 - 6 - 

	 	(vii)	securities issued pursuant to the terms of this Agreement. 

 (e) Standstill Agreement. The Purchaser covenants and agrees that, if the Company provides notice to the Purchaser pursuant to this Section 4 of any planned issuance of New Securities, then until the earlier of (i) the date
that is the second full trading day after the Company’s public announcement of its planned issuance of New Securities, (ii) the date that is the ninetieth (90th) calendar day after the Company has first delivered to the Purchaser a
notice of a planned issuance of New Securities and (iii) the date that the Company notifies the Purchaser that it has abandoned plans to issue New Securities, the Purchaser shall maintain the confidentiality of all information provided to the
Purchaser relating to any planned issuance of New Securities and shall not sell, agree to sell, buy or agree to buy, otherwise engage in any short selling of the Company’s securities, or establish or increase any “put equivalent
position” as defined in Rule 16(a)-1(h) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with respect to any of the Company’s securities other than buying securities from the Company in
accordance with the terms offered for the New Securities and the purchase of shares pursuant to the rights set forth in this Section 4. Notwithstanding the foregoing, the Purchaser agrees that, so long as the Purchaser is an affiliate (as
defined by Rule 144(a)(1) of the Securities Act) of the Company, if requested by the Company and the managing underwriter or lead placement agent of an offering of securities by the Company, the Purchaser will enter into an agreement for the benefit
of such underwriter or placement agent, not to sell, transfer or dispose of any shares for a specified period of time (not to exceed 90 days plus any extension of such period imposed pursuant to NASD Rule 2711(f)(4) not to exceed 36 days) provided
that all executive officers and directors of the Company enter into similar agreements. 
 5. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

 The Company represents and warrants to the Purchaser, subject to such exceptions as are set forth in the SEC Documents (as defined below)
or as otherwise disclosed in the Company’s disclosure letter previously delivered to the Purchaser, as follows: 
 (a) Organization
and Qualification. The Company is a corporation, duly organized, validly existing and in good standing under the laws of the Commonwealth of Massachusetts, and has the requisite corporate power and authority to own its properties and to carry on
its business as now being conducted and as described in the SEC Documents. Copies of the Company’s Articles of Organization and Bylaws, and all amendments thereto, have been filed as exhibits to the Company’s SEC Documents and have not
been further modified, and the Company has no present intention to modify the Articles of Organization and Bylaws. The Company is duly qualified as a foreign corporation to do business, and is in good standing, in every jurisdiction in which its
ownership of property or the nature of the business conducted and proposed to be conducted by it makes such qualification necessary, except where the failure to be so qualified or in good standing would not, individually or in the aggregate, have or
reasonably be expected to result in a Material Adverse Effect. 
 (b) Subsidiaries. Each of the Company’s Subsidiaries has been
duly organized and is validly existing and in good standing under the laws of its jurisdiction of organization, is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction in which its ownership or lease of
property or the conduct of its business requires such qualification, and has all power 

  

 - 7 - 

 
and authority necessary to own or hold its properties and to conduct the business in which it is engaged, except where the failure to so qualify or have such
power or authority would not have, singularly or in the aggregate, a Material Adverse Effect. All the outstanding shares of capital stock of each Subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned
by the Company directly or indirectly through one or more wholly-owned subsidiaries, free and clear of any claim, lien, encumbrance, security interest, restriction upon voting or transfer or any other claim of any third party. No Subsidiary is
currently prohibited, directly or indirectly, under any agreement to which it is a party, from paying any dividends to the Company, from making any other distribution on such Subsidiary’s capital stock, from repaying to the Company any loans or
advances to such Subsidiary from the Company or from transferring any of such Subsidiary’s properties or assets to the Company or any other subsidiary of the Company. For purposes of this Agreement, “Subsidiaries” means those
entities that are “significant subsidiaries” of the Company as determined in accordance with Regulation S-X. 
 (c)
Authorization; Enforcement; Validity. The Company has the requisite corporate power and authority to enter into and perform its obligations under the Transaction Documents, and to issue the Convertible Note and the Warrant and any shares of
Common Stock issuable upon conversion or exercise of the Convertible Note or Warrant (the “Shares” and together with the Convertible Note and the Warrant, the “Securities”) in accordance with the terms thereof. The
execution and delivery of the Transaction Documents by the Company and the consummation and performance by the Company of the transactions contemplated thereby, including, without limitation, the issuance of the Securities, have been duly authorized
by all requisite corporate action. The Transaction Documents have been duly executed and delivered by the Company. The Transaction Documents constitute the valid and binding obligations of the Company enforceable against the Company in accordance
with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the
enforcement of creditors’ rights and remedies. 
 (d) Capitalization. The capitalization of the Company is as described in the
Company’s most recent periodic report filed with the SEC as updated by any current report filed with the SEC thereafter, and all of the issued shares of capital stock of the Company have been duly and validly authorized and issued, are fully
paid and non-assessable, and have been issued in compliance with federal and state securities laws. The Company has not issued any capital stock since such filings other than pursuant to the exercise of stock options under the Company’s stock
option plans, the issuance of shares of Common Stock to employees pursuant to the Company’s employee stock purchase plan (such issuances and any such stock options, whenever issued or granted, being collectively “Employee Equity
Transactions”), pursuant to the conversion or exercise of outstanding securities that are convertible into or exercisable for Common Stock, or pursuant to publicly disclosed equity financings. The Company’s Common Stock is registered
pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), and is listed for trading on the Nasdaq Capital Market
(“Nasdaq”). Except with respect to the minimum bid price requirement as disclosed in the SEC Documents, the Company is in compliance with the continued listing criteria of Nasdaq and all Nasdaq corporate governance requirements that
are applicable to the Company. Except for Employee Equity Transactions and 

  

 - 8 - 

 
as set forth in the SEC Documents, (i) no shares of the Company’s capital stock are subject to preemptive rights or any other similar rights or any
liens or encumbrances; (ii) there are no outstanding options, warrants, rights to subscribe to, calls or commitments relating to, or securities or rights convertible into, any shares of capital stock of the Company or any of its Subsidiaries,
or contracts, commitments, understandings or arrangements by which the Company is or may become bound to issue additional shares of capital stock of the Company or any of its Subsidiaries or options, warrants, rights to subscribe to, calls or
commitments relating to, or securities or rights convertible into, any shares of capital stock of the Company or any of its Subsidiaries. 
 (e) Issuance of Securities. Except for the Shareholder Approval required by Section 2 and, if shareholder approval of an amendment of the Company’s articles of organization to increase the number of authorized shares of
Common Stock to 210,000,000 shares is not received, the Reverse Stock Split, in each case which shall be obtained or effected, as applicable, prior to the Closing, (i) the Convertible Note has been duly authorized and, upon issuance in
accordance with the terms hereof, will be a legal, valid and binding obligation of the Company in accordance with its terms and (ii) the Shares are duly authorized and, upon issuance in accordance with the terms of the Convertible Note, will be
(A) validly issued, fully paid and non-assessable and (B) free from all taxes, liens and charges in the United States of America with respect to the issuance thereof, other than any liens or encumbrances created by or imposed by the
Purchaser, and not subject to preemptive rights or other similar rights of stockholders of the Company. Except for the filing of any notice prior or subsequent to the Closing that may be required under applicable state and/or Federal securities laws
(or comparable laws of any other jurisdiction) or the rules of Nasdaq, no authorization, consent, approval, license, exemption of or filing or registration with any court or governmental department, commission, board, bureau, agency or
instrumentality, is or will be necessary for, or in connection with, the execution and delivery by the Company of the Transaction Documents, for the offer, issue, sale, execution or delivery of the Securities, or for the performance by the Company
of its obligations under the Transaction Documents. 
 (f) No Conflicts. The execution, delivery and performance of the Transaction
Documents by the Company and the consummation by the Company of the transactions contemplated thereby do not and will not (i) result in a violation of the Company’s Articles of Organization or Bylaws; (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a default) under any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party; (iii) result in a violation of any law, rule,
regulation, order, judgment or decree applicable to the Company or any of its Subsidiaries; or (iv) result in the imposition of a mortgage, pledge, security interest, encumbrance, charge or other lien on any asset of the Company or its
Subsidiaries, except for such conflicts, defaults, terminations, amendments, accelerations, cancellations, violations and impositions as described in clauses (ii), (iii) or (iv) of this sentence as would not, individually or in the
aggregate, have or result in a Material Adverse Effect. 
 (g) No Violation or Default. Neither the Company nor any of its
Subsidiaries is (i) in violation of its Articles of Organization or Bylaws or other organizational documents; (ii) in default (or subject to an event which with notice or lapse of time or both would become a default) under any agreement,
indenture or instrument to which the Company or any of its Subsidiaries is a party; or (iii) in 

  

 - 9 - 

 
violation of any law, rule, regulation, order, judgment or decree applicable to the Company or any of its Subsidiaries; except for such violations or
defaults, as described in clauses (ii) or (iii) of this sentence as are set forth in the SEC Documents or as would not, individually or in the aggregate, have or result in a Material Adverse Effect. 
 (h) SEC Documents. The Company has filed all reports, schedules, forms, statements, exhibits (including certifications of the Company’s of
the Company’s principal executive and financial officers pursuant to Section 302 and 906 of Sarbanes-Oxley (as defined in Section 5(s))) and other documents required to be filed by it with the SEC pursuant to the reporting
requirements of the Exchange Act for the twelve (12) months preceding the date hereof (all of the foregoing filed prior to or on the date hereof, or prior to or on the Closing Date, and all exhibits included therein and financial statements and
schedules thereto and documents incorporated by reference therein being referred to in this Agreement as the “SEC Documents”). As of the date of filing of each such SEC Document, such SEC Document, as it may have been subsequently
amended by filings made by the Company with the SEC prior to the date hereof, complied in all material respects with the requirements of the Exchange Act and the rules and regulations of the SEC promulgated thereunder applicable to such SEC
Document. None of the SEC Documents, as of the date filed and as they may have been subsequently amended by filings made by the Company with the SEC prior to the date hereof, contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 (i) Financial Statements. The financial statements and the related notes thereto of the Company and its consolidated subsidiaries included or
incorporated by reference in the SEC Documents comply in all material respects with the applicable requirements of the Exchange Act, as applicable, and present fairly the financial position of the Company and its subsidiaries as of the dates
indicated and the results of their operations and the changes in their cash flows for the periods specified. Such financial statements have been prepared in conformity with United States generally accepted accounting principles
(“GAAP”) applied on a consistent basis throughout the periods covered thereby, except as specifically stated therein, and the supporting schedules included or incorporated by reference in the SEC Documents present fairly the
information required to be stated therein. 
 (j) No Material Adverse Change. Since the date of the most recent financial statements
of the Company included or incorporated by reference in the SEC Documents, (i) there has not been any change in the capital stock (other than pursuant to Employee Equity Transactions, pursuant to the conversion or exercise of outstanding
securities that are convertible into or exercisable for Common Stock, or pursuant to publicly disclosed equity financings) or long-term debt of the Company or any of its subsidiaries, or any dividend or distribution of any kind declared, set aside
for payment, paid or made by the Company on any class of capital stock, or any material adverse change in or affecting the business, properties, management, financial condition or operations of the Company and its subsidiaries taken as a whole;
(ii) neither the Company nor any of its subsidiaries has entered into any transaction or agreement that is material to the Company and its subsidiaries taken as a whole or incurred any liability or obligation, direct or contingent, that is

limitation, those administered by the FDA or by any foreign, federal, state or local government or regulatory authority performing functions similar to those performed by the FDA) except where the failure to comply with such statutes, laws, rules or

ordinance, rule (including rule of common law), regulation, order, judgment, decree or permit, give rise to any liability, except for any violation or liability which would not have, singularly or in the aggregate with all such violations and
liabilities, a Material Adverse Effect. There has been no disposal, discharge, emission or other release of any kind onto such property or into the environment surrounding such property of any toxic or other wastes or other hazardous substances with
respect to which the Company has knowledge, except for any such disposal, discharge, emission, or other release of any kind which would not have, singularly or in the aggregate with all such discharges and other releases, a Material Adverse Effect.

franchise tax returns, (ii) has paid all federal state, local and foreign taxes due and payable for which it is liable, and (iii) does not have any tax deficiency or claims outstanding or assessed or, to the best of the Company’s
knowledge, proposed against it, except where the failure to file, failure to pay or the deficiency or claim would not have a Material Adverse Effect.

upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth in this Agreement in order to determine the availability of such
exemptions and the eligibility of the Purchaser to acquire the Securities. 
 (g) No Governmental Review. The Purchaser understands

position in the Common Stock that is outstanding on the Closing Date and that is designed to or could reasonably be expected to lead to or result in a disposition by the Purchaser or any other person or entity. For purposes hereof, a “hedge
or other position” includes, without limitation, effecting any short sale or having in effect any short position (whether or not such sale or position is against the box and regardless of when such position was entered into) or any
purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to the Common Stock or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any
significant part of its value from the Common Stock. The Purchaser acknowledges that this representation is made for the benefit of the Company. 
 (l) Short Sales and Confidentiality After the Date Hereof. The Purchaser understands and acknowledges that the transactions contemplated by this Agreement constitute “material non-public information” within the meaning of
the rules and regulation promulgated by the SEC under Regulation FD and that until such time as such the transactions have been publicly disclosed in accordance with Section 12 or otherwise, the Purchaser represents, warrants and covenants that
neither it nor any of its affiliates acting on its behalf or pursuant to any understanding with it have executed or will execute any short sales of the Company’s Common Stock and that it will maintain the confidentiality of all disclosures made
to it in connection with the Offering (including the existence and terms of this Agreement and the Development Agreement and the transactions contemplated hereby and thereby). 
 (m) Ownership. The Purchasers current beneficial ownership of the Company’s common stock is accurately reported in the Purchaser’s most
recent Schedule 13D filed with the SEC. 
 7. BOARD REPRESENTATIVES 
 (a) Appointment of Purchaser Designees. Upon Conversion of the Convertible Note in full or in part from time to time by the Purchaser in accordance
with its terms, the Purchaser shall be entitled to designate one or more Purchaser Designees (as defined below) to the Company’s Board, as provided herein. Within five (5) business days of receipt by the Company of a written designation

  

 - 15 - 

 
by the Purchaser of the Purchaser Designees, including the designees’ Company stock ownership, Company relationships and biographical information as
provided by current members of the Board, the Company’s Board of Directors shall by written consent or meeting appoint the Purchaser Designees (as defined below) to the Company’s Board of Directors. If the Convertible Note is converted in
part, the Purchaser shall have the right to have a pro rata portion of the Purchaser Designees appointed. Purchaser Designees shall be appointed across the three classes of directors in as equal proportion as possible. For purposes of this
Section 7, “Purchaser Designees” shall mean the maximum number of directors that may be appointed under the rules of Nasdaq in connection with this Agreement and the transactions contemplated hereby. The Company shall within
five (5) business days of the date of this Agreement send to Nasdaq a request for a written determination (on an expedited basis) of the maximum number of directors that may be appointed by Purchaser under this Section 9 (the
“Nasdaq Determination”), the costs of which shall be borne solely by the Company. If, and only if, required pursuant to the Nasdaq Determination, if the Purchaser’s ownership decreases, the number of Purchaser Designees would
decrease ratably such that the percentage of the Board represented by the Purchaser Designees would not exceed the Purchaser’s percentage equity ownership in the Company. 
 (b) Nomination of Purchaser Designees. For so long as Purchaser’s ownership of Common Stock of the Company is at least twenty-one percent
(21%) on an as-converted basis, any Purchaser Designee (including any successor pursuant to Subsection 7(d) below) shall be nominated by the Board of Directors (or a committee thereof) for election at the annual meeting of stockholders at which
such Purchaser Designee’s term will expire. At least ninety (90) days prior to any such annual meeting at or by which directors are to be elected, the Purchaser shall notify the Company in writing of the Purchaser Designee(s) to be
nominated for election as a director. The Company shall disclose in its proxy the nominated Purchaser Designee(s). In the absence of any such notification, it shall be presumed that the Purchaser’s then incumbent Purchaser Designee(s) has been
renominated as its Purchaser Designee(s). The rights provided under this Section 7 are the exclusive rights of the Purchaser and are not transferable. 
 (c) Restrictions on Purchaser Designees. The Purchaser Designees (i) shall be bound by confidentiality obligations with respect to the Company and its business to the same extent as are other directors of
the Company and as is the Purchaser pursuant to this Agreement; and (ii) if deemed necessary by a determination of the Chairman of the Board or a vote of the majority of the independent members of the Board, shall not participate in any Board
deliberations or action (including, but not limited to, Board presentations or discussions), or receive Board information, relating to any matter to which the Purchaser is either directly or indirectly involved or has any interest that is competing
or inconsistent with the interests of the Company. The Purchaser agrees to cause the Purchaser Designees (and each successor) to comply with the obligations in clause (i) of the preceding sentence for the benefit of the Company and its
successors. 
 (d) Successor Designees. If a Purchaser Designee shall cease to serve as a director for any reason, the Company’s
Board of Directors shall appoint and elect a replacement director to serve out the remaining term of the existing director upon written notice to the Company by the Purchaser. 
  

 - 16 - 

 (e) Indemnification Agreement. The Company shall enter into an Indemnification Agreement with each
Purchaser Designee or Successor Designee prior to the commencement of his or her service on the Board, which agreement shall be in such form and substance as has been executed by the current members of the Board. 
 (f) No Increase to Size of Board of Directors. The Company hereby covenants and agrees that after the date of this Agreement, unless the
Convertible Note is prepaid in full on or prior to June 1, 2009 in accordance with Section 1.4 thereof, the Company will not, without the prior written consent of the Purchaser, which consent can be withheld in the Purchaser’s sole
discretion, increase the size of the Board of Directors, except in connection with the appointment of one or more Purchaser Designees in accordance with this Section 7. 
 8. RESTRICTIONS ON TRANSFER 
 (a)
Resales. The Purchaser agrees that the Securities, including the Shares, may only be sold or transferred (i) pursuant to an effective Registration Statement under the Securities Act, or (ii) pursuant to an exemption from
registration under the Securities Act. 
 (b) Rule 144. The Purchaser is aware of Rule 144 under the Securities Act and the
restrictions imposed thereby and further understands and agrees that so long as the Purchaser beneficially owns 10% or more of the Company’s then outstanding securities or has a Purchaser Designee serving on the Board, the Company will deem the
Purchaser to be an “affiliate” as defined in Rule 144(a)(1) and any transfers of the Shares by the Purchaser shall be subject to the limitations applicable to affiliates set forth in the Securities Act and the rules promulgated thereunder,
including without limitation Rule 144. 
 (c) Legends. The Convertible Note and the Warrant shall bear legends in the form set forth
on Exhibit A and Exhibit B, respectively. The certificate(s) evidencing the Shares shall bear legends in substantially the following form: 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON THE TRANSFER THEREOF PURSUANT TO THE TERMS OF A NOTE AND WARRANT PURCHASE AGREEMENT BETWEEN THE HOLDER AND THE COMPANY AND
SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR HYPOTHECATED UNTIL SUCH RESTRICTIONS HAVE LAPSED OR HAVE BEEN WAIVED BY THE WRITTEN CONSENT OF THE COMPANY. THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED EXCEPT (A) IN
AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S OF THE SECURITIES ACT, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR (C) PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO,
THE REGISTRATION 

  

 - 17 - 

 
REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO
SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.” 
 (d) Agreement to be Bound. Subject to the
other restrictions on transfer set forth or referenced in this Agreement (including those set forth in Section 11(h)), the Convertible Note or the Warrant, the Purchaser may assign all of its rights and obligations hereunder with respect to the
Convertible Note, the Warrant and some or all of the Shares, provided that the transferee has agreed in writing to be bound by the applicable provisions of this Agreement. 
 (e) Security Ownership. The Purchaser is aware that the Company is a party to a Shareholder Rights Agreement, dated as of May 31, 2001,
between the Company and American Stock Transfer and Trust Company (the “Rights Agreement”), which provides that in the event the Purchaser at any time beneficially owns 15% or more of the Company’s then outstanding capital
stock, the Purchaser may be deemed an “Acquiring Person” as defined in the Rights Agreement. The Purchaser understands that, in connection with the Purchaser’s acquisition of the Securities and the Shares and with respect to
the Purchaser’s equity position in the Company, the Company has exempted the Purchaser from being deemed an Acquiring Person as a result of such acquisition or any subsequent transaction so long as the Purchaser acquires its beneficial
ownership of shares of capital stock of the Company in a transaction whereby the Purchaser is acquiring such beneficial ownership directly from the Company. Notwithstanding the foregoing, the Purchaser will also not be deemed an Acquiring Person if
the percentage of outstanding capital stock owned by the Purchaser increases solely due to the repurchase by the Company of shares of its outstanding capital stock. 
 9. GUARANTEES AND OTHER OBLIGATIONS AND COVENANTS OF THE COMPANY 
 (a) Financial Information. From the
date of this Agreement through the Closing, and after the Closing, for so long as any portion of the Convertible Note is outstanding and the Purchaser’s ownership of Common Stock of the Company is at least twenty percent (20%) on an
as-converted basis, the Company shall provide the Purchaser (i) as soon as practicable after the end of each month, and in any event within thirty (30) days thereafter, unaudited monthly income, balance sheet and cash flow statements and a
monthly cash flow budget, (ii) as soon as practicable after the end of each quarter, and in any event within forty-five (45) days thereafter, a consolidated balance sheet of the Company and its subsidiaries as of the end of each such

 - 18 - 

 (b) Trade Debt. At no time during the period from the date of this Agreement through the Closing,

exceed $5,000,000 in the aggregate. 
 (c) Right of First Negotiation on Partnership/Licensing Opportunities. The Company hereby
covenants and agrees that in the event that after June 1, 2009 the Company decides to grant a license, sublicense or similar rights to a third party or to enter into a partnership, collaboration or other arrangement to participate in, or lead,
the effort to develop or commercialize any Invention or therapeutic product developed by the Company (including the Company’s interest in any Joint Inventions) pursuant to the terms of the Amended and Restated Joint Development and
Commercialization Agreement entered into by the Company, the Purchaser and the other parties named therein as of June 30, 2008 (the “JDA”), the Company shall give written notice of such decision to the Purchaser, which notice
shall include a detailed description of the terms and conditions with respect to such proposed license or other arrangement. Upon receipt of such notice, the Purchaser shall have a period of thirty (30) days to indicate by written notice to the
Company that it desires to exercise a right of first negotiation with respect to such proposed license, sublicense or other arrangement. If the Purchaser timely notifies the Company of its desire to exercise its right of first negotiation, then the
parties shall negotiate exclusively and in good faith with each other to finalize terms and definitive documentation, for a period of up to sixty (60) days. If the Parties fail to finalize terms and execute and deliver definitive documentation
in such sixty (60) day period, the Company shall be entitled to enter into the proposed license, sublicense or other arrangement with the third party, provided however, that such license, sublicense or arrangement must not be on terms, economic
and otherwise, which are more favorable to such third party than those offered by the Purchaser. 
 (d) Guarantees. Effective upon the
Closing: 
  

	 	(i)	The Company shall be deemed to have granted to the Purchaser an exclusive (even as to the Company), fully-paid, royalty-free, right and license or sublicense, as the case may be,

collaboration or other arrangement to participate 

  

 - 19 - 

	 	 
in, or lead, the effort to develop or commercialize any such transgenic compound Controlled by the Company that is biosimilar to anti-TNFa/Etanercept/Infliximab, provided however, that the Company shall give written notice of such decision to the Purchaser, and the parties shall negotiate in good faith an appropriate amendment to the license or sublicense
described in this Section 9(d)(iii) to include a comparable compound as a substitute for the Purchaser’s license or sublicense to the foregoing compound. 

 All capitalized terms not otherwise defined in this Section 9 shall have the meaning ascribed to them in the JDA. The rights, licenses and
sublicenses described in Sections 9(d)(i), (ii) and (iii) above shall be terminated if there has been no Event of Default (as defined in the Convertible Note) and the Convertible Note is paid in full or converted in full on or prior to the
Maturity Date (as defined in the Convertible Note). If an Event of Default shall occur or the Convertible Note is not paid in full or converted in full on or prior to the Maturity Date, the rights, licenses and sublicenses described in Sections
9(d)(i), (ii) and (iii) above shall automatically become perpetual and non-terminable. The Parties agree to take such actions as may be necessary to prepare and execute an amendment to the JDA to reflect the rights of the Purchaser set

	 	                    , 200    

 Subject to the terms and conditions of this Note, for good and valuable consideration received,
GTC BIOTHERAPEUTICS, INC., a Massachusetts corporation (the “Company”), promises to pay to LFB BIOTECHNOLOGIES, a société anonyme established under the laws of France (the “Holder”), the principal amount of
fifteen million dollars (US$15,000,000), plus interest which shall accrue at the rate of eight percent (8%) per annum on the unpaid principal from the date of this Note until the Maturity Date (as defined in Section 1.1) or until the full
amount of principal and accrued interest under this Note is earlier paid or converted under the terms hereof. The following is a statement of the rights of the Holder and the terms and conditions to which this Note is subject, and to which the
Holder hereof, by the acceptance of this Note, agrees: 
 1. Payment 
 1.1. Principal. The principal under this Note will be paid to the Holder on June 30, 2012 (the “Maturity Date”) to the extent it has
not been earlier paid in full or converted pursuant to the terms hereof. 
 1.2. Interest. Interest shall accrue on the then
outstanding principal balance of this Note at a fixed interest rate per annum equal to 8%. Accrued interest shall be payable in cash in arrears on the last day of each fiscal quarter commencing on December 31, 2008, until the outstanding
principal balance is paid in full or converted pursuant to the terms hereof. If at any time the principal balance of this Note shall be paid in full or converted pursuant to the terms hereof, then all accrued interest shall be payable at the time of
such principal payment. 
 1.3. Payment. All payments of principal and interest under this Note will be made by wire transfer of
immediately available funds in accordance with the wire transfer instructions of Holder provided to the Company except. 
 1.4.
Prepayment. Except as set forth in Section 3 below, this Note may not be prepaid without the written consent of the Holder. 

 2. Conversion. 
 2.1. Optional Conversion. After June 1, 2009, the outstanding principal balance of this Note may at the sole option of the Holder be converted, in whole or in part, into fully paid and non-assessable
shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), at a conversion price equal to $0.31 per share (the “Conversion Price”), subject to adjustment as set forth herein. 
 2.2. Mechanics of Conversion. The Holder shall notify the Company of its election to convert all or part of this Note in accordance with
Section 2.1. The Company shall, as soon as practicable but in no event later than three days following its receipt of such notice, issue and deliver to Holder a certificate or certificates for the number of shares of Common Stock to which such
holder shall be entitled, together with cash in lieu of any fractional share in accordance with Section 2.3. This Note shall be deemed to have been converted and a certificate or certificates for shares of Common Stock shall be deemed to have
been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes as of the date said notice is received by the Company. If this Note shall have been
converted in part, the Company shall, at the time of delivery of said certificate or certificates, deliver to the Holder a new Note evidencing the remaining outstanding principal balance of this Note, which new Note shall in all other respects be
identical with this Note. Upon conversion of this Note in full, this Note shall no longer be deemed to be outstanding and all rights with respect to this Note shall immediately cease and terminate on such conversion date, except only the right of
the Holder to receive the shares of Common Stock to which it is entitled as a result of the conversion. 
 2.3. Fractional Shares. No
fractional shares of Common Stock shall be issued upon conversion of this Note. In lieu of any fractional shares to which the holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the Conversion Price.

 2.4. Subdivision or Combination of Common Stock. If the Company at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced, and if the Company at any time combines (by
reverse stock split, recapitalization or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased. 
 2.5. Merger, Consolidation or Sale of Assets. If there shall be a merger or consolidation of the Company with or into another corporation (other
than a merger or reorganization involving only a change in the state of incorporation of the Company), or the sale of all or substantially all of the Company’s capital stock or assets to any other person, then as a part of such transaction,
provision shall be made so that the Holder hereof shall thereafter be entitled to receive the number of shares of stock or other securities or property of the Company, or of the successor corporation resulting from the merger, consolidation or sale,
to which the Holder would have been entitled if the Holder had converted this Note immediately prior thereto. 
  

 - 2 - 

 2.6. Notice of Adjustment to Conversion Price. Upon any adjustment or other change relating to the
Conversion Price or the securities issuable upon the conversion of this Note, then, and in each such case, the Company shall give written notice thereof, which notice shall state the Conversion Price resulting from such adjustment and the increase
or decrease in the number or other denominations of securities issuable at such price upon the conversion of this Note setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 
 2.7. Reservation of Shares. The Company covenants that it will at all times until this Note is paid or converted in full under the terms hereof

Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the
Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Company shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall deliver to the Holder, at least twenty (20) calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the
Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to
become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer or share exchange. The Holder is entitled to convert this Note during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice.

 3. Optional Company Redemption. At any time on or before June 1, 2009, the Company shall have the right to redeem all of the
then outstanding principal of this Note for a price equal to the outstanding principal amount plus all accrued and unpaid interest.

Warrant Expiration Date, for all or any part of the number of shares of Common Stock set forth above. In order to exercise this Warrant, in whole or in part, the Holder shall deliver to the Company at its principal executive offices, or at such
other office as the Company may designate by notice in writing, (i) this originally executed Warrant and (ii) a duly executed written notice of Holder’s election to exercise its Warrant in whole or in part substantially in the form of

Common Stock as to which this Warrant is exercised. 
 (b) Notification Prior to Warrant Expiration Date. No earlier than 45 days prior
to the Warrant Expiration Date and no later than 30 days prior to the Warrant Expiration Date, the Company shall deliver to the Holder written notice which notice shall indicate: (i) the Warrant Expiration Date, (ii) the number of shares

 3. Holder’s Redemption Right. If the Convertible Note issued to the Holder pursuant to the
Purchase Agreement (the “Note”) is repaid in full in accordance with the terms thereof, Holder has the right, exercisable for a period of 90 days from the date that the Note is repaid in full to require the Company to redeem this Warrant
for a redemption price equal to US $1,500,000 (the “Redemption Price”). If this Warrant has been exercised in part or in full prior to the date that the Holder exercises its rights under this Section 3, Holder shall, in its sole
option, have the right to require the Company to redeem (i) the Warrant and all shares of Common Stock previously issued to Holder upon exercise of the Warrant in which case it will be entitled to the full Redemption Price or (ii) only the
remaining Warrant in which case it shall be entitled to a pro rata portion of the Redemption Price based on the ratio of the number of shares of Common Stock still issuable upon exercise of the Warrant to the number of shares of Common Stock
originally issuable upon exercise of the Warrant (as adjusted pursuant to Sections 6 and 7 hereof). In the event that this redemption right is triggered by the repayment in full of the Note at the Maturity Date (as defined in the Note) and the
Holder timely exercises its right of redemption hereunder, then the Company shall have the option to pay the Redemption Price in shares of Common Stock based on the Fair Market Value of the Common Stock on the date that Holder notifies the
Company of its decision to exercise the right of redemption (or if such date is not a Trading Day, then on the nearest Trading Day preceding such date). For purposes of this Section 3: 
  

	 	(a)	“Fair Market Value” of a share of Common Stock on any Trading Day shall be deemed to be: 

  

	 	(i)	if the Common Stock is listed on a national securities exchange or traded in the over-the-counter market, and sales prices are regularly reported for the Common Stock, the closing
or last sale price of the Common Stock on the composite tape or other comparable reporting system for such Trading Day; and 

  

	 	(ii)	if the Common Stock is not traded on a national securities exchange but is traded on the over-the-counter market, if sales prices are not regularly reported for the Common Stock for
the Trading Day referred to in clause (i), and if bid and asked prices for the Common Stock are regularly reported, the mean between the bid and the asked price for the Common Stock at the close of trading in the over-the-counter market for such
Trading Day. 

  

	 	(b)	“Trading Day” shall mean a day on which the principal national securities exchange on which such security is listed or admitted to trading is open for the
transaction of business or, if such security is not listed or admitted to trading on any national securities exchange, but is traded on the over-the-counter market, a day on which such over-the-counter market is open for the transaction of business.

 4. Reservation of Shares. The Company covenants that it will at all times until the Warrant
Expiration Date reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of issue upon exercise of this Warrant, such number of shares of Common Stock as shall then be issuable upon the exercise of this
Warrant. 
 5. Loss, Theft, Destruction or Mutilation. Upon receipt of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant (including a reasonably detailed affidavit with respect to the circumstances of any loss, theft or destruction of such Warrant), and, in the case of any such mutilation, upon surrender and cancellation of
this Warrant, the Company at its expense will execute and deliver, in lieu hereof, a new Warrant of like tenor. 
 6. Subdivision or
Combination of Common Stock. If the Company at any time subdivides (by any stock split, stock dividend, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Stated Purchase Price in effect
immediately prior to such subdivision will be proportionately reduced and the number of shares issuable upon exercise of this Warrant will be proportionately increased, and if the Company at any time combines (by reverse stock split,
recapitalization or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Stated Purchase Price in effect immediately prior to such combination will be proportionately increased and the number of shares issuable upon
exercise of this Warrant will be proportionately decreased. 
 7. Consolidation, Merger, etc. If there shall be a merger or
consolidation of the Company with or into another corporation (other than a merger or reorganization involving only a change in the state of incorporation of the Company), or the sale of all or substantially all of the Company’s capital stock
or assets to any other person, then as a part of such transaction, provision shall be made so that the Holder hereof shall thereafter be entitled to receive the number of shares of stock or other securities or property of the Company, or of the
successor corporation resulting from the merger, consolidation or sale, to which the Holder would have been entitled if the Holder had exercised this Warrant immediately prior thereto. 
 8. Notice of Adjustment of Stated Purchase Price. Upon any adjustment or other change relating to the Stated Purchase Price or the securities
purchasable upon the exercise of this Warrant, then, and in each such case, the Company shall give written notice thereof, which notice shall state the Stated Purchase Price resulting from such adjustment and the increase or decrease in the number
or other denominations of securities purchasable at such price upon the exercise of this Warrant setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 
 9. Notice to Allow Exercise. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock,
(B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a
party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is 

  

 - 4 - 

 
converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up
of the affairs of the Company, then, in each case, the Company shall deliver to the Holder, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that
holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange. The Holder
is entitled to exercise this Warrant during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice. 
 10. Fractional Shares. If the number of shares of Common Stock purchasable upon the exercise of this Warrant is adjusted pursuant to the terms hereof, the Company shall nevertheless not be required to issue
fractions of shares, upon exercise of this Warrant or otherwise, or to distribute certificates that evidence fractional shares. With respect to any fraction of a share called for upon any exercise hereof, such fraction shall neither be issued nor
extinguished until the final exercise of this Warrant, in which event if a fraction is issuable, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the Stated Purchase Price, as adjusted to date pursuant to
Section 6 or 7. 
 11. Holder Not Deemed Stockholder. The Holder shall not be entitled to vote or to receive dividends or be
deemed the holder of Common Stock that may at any time be issuable upon exercise of this Warrant for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to receive dividends or subscription rights, until Holder shall have exercised this Warrant in accordance with the provisions
hereof. 
 12. Rights of Action; Remedies. All rights of action with respect to this Warrant are vested in the Holder, and the Holder
may enforce against the Company its right to exercise this Warrant for the purchase of shares of Common Stock in the manner provided in this Warrant. The Company stipulates that the remedies at law of the Holder in the event of any default or
threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

under the laws of the state of Massachusetts (the “State”). Debtor’s mailing address and chief place of business is 175 Crossing Blvd., Framingham, MA 01702. 
 RECITALS: 
 WHEREAS, pursuant to that certain Note and Warrant Purchase
Agreement by and between the Debtor and the Secured Party as of the date hereof (the “Purchase Agreement”), the Debtor is issuing and selling to the Secured Party a secured convertible note in the original principal amount of $15,000,000
the “Convertible Note”) and a warrant to purchase up to 23,193,548 shares of common stock of the Debtor. 
 WHEREAS, it is a
condition to the Purchase Agreement that the Debtor execute and deliver this Agreement, pursuant to which the obligations of the Debtor to the Secured Party under the Purchase Agreement and the Convertible Note are secured. 
 NOW, THEREFORE, in consideration of the mutual covenants and undertakings herein contained, Debtor and Secured Party agree as follows: 

 

	1.	CREATION OF SECURITY INTEREST. 

 Debtor grants to
Secured Party, its successors and assigns, a continuing security interest in, to and against all property listed on any collateral schedule now or in the future annexed to or made a part of this Agreement (“Collateral Schedule”),
including without limitation the property listed on Collateral Schedule No. 1 and Collateral Schedule No. 2, whether now owned or existing or hereafter acquired or arising and wheresoever located, and in and against all additions,
attachments, accessories and accessions to such property, all substitutions, replacements or exchanges therefor, and all proceeds or products thereof, in whatever form, including without limitation cash, deposit accounts (whether or not comprised
solely of proceeds), certificates of deposit, insurance proceeds (including hazard, flood and credit insurance), negotiable instruments for the payment of money, chattel paper, security agreements, documents, eminent domain proceeds, condemnation
proceeds and/or tort claim proceeds (all such property is individually and collectively called the “Collateral”). This security interest is given to secure the payment and performance of all debts, obligations and liabilities of any
kind whatsoever (including all interest (whether or not allowed or disallowed), charges, expenses, fees and other sums accruing after commencement of any case, proceeding or other action relating to the bankruptcy, insolvency or reorganization of
Debtor) of Debtor to Secured Party, now existing or arising in the future, including but not limited to the payment and performance of the Convertible Note or other promissory notes from time to time identified on any Collateral Schedule
(collectively “Notes” and each a “Note”), the Purchase Agreement, together with all Schedules and attachments thereto and any renewals, extensions and modifications of such debts, obligations and liabilities (such
Notes, Purchase Agreement, Schedules, debts, obligations and 

 
liabilities are called the “Indebtedness”). The Collateral listed on Collateral Schedule No. 1 to this Security Agreement has been
subordinated to certain senior debt pursuant to the provisions of an intercreditor agreement dated as of                     ,
200    , among the Debtor, the Secured Party and General Electric Capital Corporation (the “GECC”). Pursuant to this Security Agreement, the Debtor is granting to the Secured Party a first priority security

(ii) shall not and shall not allow any of its Subsidiaries to open or maintain any securities, depository or disbursement accounts except upon thirty (30) days’ prior written notice to Secured Party, and Debtor shall not, and shall

a control agreement satisfactory to Secured Party in its reasonable discretion and in any event sufficient to perfect a first priority lien and security interest in such account in favor of Secured Party. All funds in or transferred into such
account on or after the effectiveness of this Agreement shall be subject to the security interest granted under this Agreement. Each control agreement entered into pursuant to (i) or (ii) above shall grant Secured Party control of such
securities, depository or disbursement account and provide that the applicable securities intermediary or depository institution, as the case may be, will comply with instructions originated by the Secured Party directing disposition of the funds in
such account without further consent by Debtor, provided, that Debtor shall have full access to such accounts and the funds therein until the earlier to occur of (A) an Event of Default or (B) Debtor shall have acted in a fraudulent
manner or shall have committed an act of fraud; 
 (r) Debtor agrees that it shall not, and shall not allow any of its Subsidiaries to,

investments in its Subsidiaries existing as of the date hereof), or form any Subsidiary or enter into any partnership, joint venture or similar arrangement; and 
 (s) Debtor will not, and will not permit any Subsidiary to, directly or indirectly, engage in any transaction with any Affiliate, except where such transactions are (i) on terms that are no less favorable to the

its reasonable discretion, and Secured Party agrees to negotiate the form of bailee acknowledgment in good faith with each bailee. In the event that Debtor is unable to cause any of Lonza, MedImmune or Cryonix to enter into a bailee acknowledgment
within the relevant time period set forth in (B) or (C) above, Debtor shall (from the day following the expiration of such time period until such bailee acknowledgment is entered into) be prohibited from acquiring, transferring or placing

Collateral, (B) to Secured Party, (C) for maintenance and repair, (D) any sale or disposition of inventory in the ordinary course of business or the sale of equipment or other assets which are determined by the Debtor in good faith to

hereto or any sale or disposition of inventory in the ordinary course of business); or

 (iii) sell, rent, lease, mortgage, license, grant a security interest in or otherwise transfer or
encumber (except for Permitted Liens) any of its assets (including, without limitation, in respect of Debtor, the Collateral) (except for (A) any sale or disposition of inventory in the ordinary course of business, (B) the sale of
equipment or other assets which are determined by the Debtor in good faith to be obsolete or no longer used or useful in Debtor’s business, (C) transfers of Intellectual Property expressly permitted under Section 2(m), and
(D) liens on assets financed under capital leases, to the extent such the amount of related capital lease obligations together with other Debt permitted hereunder, do not violate the terms of Section 2(o). 
 (d) Debtor shall pay promptly when due all taxes, license fees, assessments and public and private charges levied or assessed on any of the Collateral,
on its use, or on this Agreement or any of the other Debt Documents. At its option, Secured Party may discharge taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral and may pay for the maintenance,
insurance and preservation of the Collateral and effect compliance with the terms of this Agreement or any of the other Debt Documents. Debtor agrees to reimburse Secured Party, on demand, all reasonable out-of-pocket costs and expenses incurred by
Secured Party in connection with such payment or performance and agrees that such reimbursement obligation shall constitute Indebtedness. 
 (e) Debtor shall, at all times, keep accurate and complete records of the Collateral, and Secured Party shall have the right to inspect and make copies of all of Debtor’s books and records relating to the Collateral during normal
business hours, after giving Debtor reasonable prior notice. 
 (f) Debtor agrees and acknowledges that any third person who may at any time
possess all or any portion of the Collateral shall be deemed to hold, and shall hold, the Collateral as the agent of, and as pledge holder for, Secured Party. Secured Party may at any time give notice to any third person described in the preceding
sentence that such third person is holding such Collateral as the agent of, and as pledge holder for, the Secured Party. 
 (g) At the
request of Secured Party, but no more frequently than once each fiscal year unless a default has occurred hereunder or Secured Party is otherwise insecure as to the value of the Collateral, upon reasonable notice to Debtor (unless a default has
occurred hereunder), Debtor shall permit Secured Party or one or more agents to perform, at Debtor’s expense, appraisals of Collateral, field examinations, collateral analysis, monitoring or other business analysis as reasonably required by
Secured party and shall provide Secured Party with access to all facilities and all books and records of Debtor reasonably required by Secured Party to conduct such audits. 
  

	4.	INSURANCE. 

 (a) Debtor shall at all times bear the
entire risk of any loss, theft, damage to, or destruction of, any of the Collateral from any cause whatsoever other than the gross negligence or willful misconduct of the Secured Party. 
  

 - 7 - 

 (b) Debtor agrees to keep the Collateral insured against loss or damage by fire and extended coverage
perils, theft, burglary, and for any or all Collateral which are vehicles, for risk of loss by collision, and if requested by Secured Party, against such other risks as Secured Party may reasonably require. The insurance coverage shall be in an
amount no less than the full replacement value of the Collateral, and deductible amounts, insurers and policies shall be acceptable to Secured Party. Debtor shall deliver to Secured Party policies or certificates of insurance evidencing such
coverage. Each policy shall name Secured Party as additional insured and lender’s loss payee, shall provide for coverage to Secured Party regardless of the breach by Debtor of any warranty or representation made therein, shall not be subject to
co-insurance and shall provide that coverage may not be canceled or altered by the insurer except upon thirty (30) days prior written notice to Secured Party. Debtor appoints Secured Party as its attorney-in-fact to make proof of loss, claim
for insurance and adjustments with insurers and to receive payment of and execute or endorse all documents, checks or drafts in connection with insurance payments. Secured Party shall not act as Debtor’s attorney-in-fact unless Debtor is in
default. Proceeds of insurance in excess of $100,000 per claim shall be applied, at the option of Secured Party, to repair or replace the Collateral or to reduce any of the Indebtedness. Proceeds of insurance below $100,000 per claim shall be
applied, at the option of Debtor, to repair or replace the Collateral or to reduce any of the Indebtedness.

Party of (i) any change in the name of Debtor, (ii) any change in the state of its incorporation, organization or registration, (iii) any relocation of its chief executive offices, (iv) any relocation of any of the Collateral,
(v) any of the Collateral being lost, stolen, missing, destroyed, materially damaged or worn out or (vi) any lien, claim or encumbrance other than Permitted Liens attaching to or being made against any of the Collateral. Debtor shall
promptly deliver to Secured Party, at Secured Party’s request, reports specifying the location and value of the Offsite Collateral. 
 (b) Debtor will deliver to Secured Party financial statements as follow: If Debtor is a privately held company, then Debtor agrees to provide monthly financial statements, certified by Debtor’s president or chief financial officer
including a balance sheet, statement of operations and cash flow statement within 30 days of each month end and its complete audited annual financial statements, certified by a recognized firm of certified public accountants, within 120 days of
fiscal year end or at such time as Debtor’s Board of Directors receives the audit. If Debtor is a publicly held company, then Debtor agrees to provide quarterly unaudited statements and annual audited statements, certified by a recognized firm
of certified public accountants, within 10 days after the statements are provided to the Securities and Exchange Commission (“SEC”). All such statements are to be prepared using generally accepted accounting principles
(“GAAP”), except that quarterly financial statements will not provide footnotes and will be subject to normal year-end adjustments and, if Debtor is a publicly held company, are to be in compliance with SEC requirements. 

 

	6.	FURTHER ASSURANCES. 

 (a) Debtor shall upon request
of Secured Party, furnish to Secured Party such further information, execute and deliver to Secured Party such documents and instruments (including, without limitation, Uniform Commercial Code financing statements) and shall do 

  

 - 8 - 

 
such other acts and things as Secured Party may at any time reasonably request relating to the perfection or protection of the security interest created by

perfected priority security interests in the Collateral established herein, and shall use commercially reasonable efforts to obtain and furnish to Secured Party any subordinations, releases, landlord waivers, lessor waivers, mortgagee waivers, or
control agreements, and similar documents as may be from time to time requested by, and in form and substance reasonably satisfactory to, Secured Party. 
 (b) Debtor authorizes Secured Party to file a financing statement and amendments thereto describing the Collateral and containing any other information required by the applicable Uniform Commercial Code. Debtor
irrevocably grants to Secured Party the power to sign Debtor’s name and generally to act on behalf of Debtor to execute and file applications for title, transfers of title, financing statements, notices of lien and other documents pertaining to
any or all of the Collateral; this power is coupled with Secured Party’s interest in the Collateral. Debtor shall, if any certificate of title be required or permitted by law for any of the Collateral, obtain and promptly deliver to Secured
Party such certificate showing the lien of this Agreement with respect to the Collateral. Debtor ratifies its prior authorization for Secured Party to file financing statements and amendments thereto describing the Collateral and containing any
other information required by the Uniform Commercial Code if filed prior to the date hereof. 
  

	7.	DEFAULT AND REMEDIES.

or any of the Collateral, which in the good faith judgment of Secured Party subjects any of the Collateral to a material risk of attachment, execution, levy, seizure or confiscation and no bond is posted or protective order obtained to negate such
risk; 
 (vii) Debtor breaches or is in default under any other agreement between Debtor and Secured Party; 
 (viii) Debtor, any material Subsidiary (including without limitation ATIII, LLC, a Delaware limited liability company), or any guarantor or other obligor
for any of the Indebtedness (collectively “Guarantor”) dissolves, terminates its existence, becomes insolvent or ceases to do business as a going concern; 
 (ix) If Debtor, any Subsidiary, or any Guarantor is a natural person, Debtor or any such Guarantor dies or becomes incompetent; 
 (x) Debtor, any Subsidiary or any Guarantor files a petition under any bankruptcy, insolvency or similar law, or any such petition is filed against
Debtor, any Subsidiary or any Guarantor and is not dismissed within sixty (60) days; 
 (xi) Debtor’s improper filing of an
amendment or termination statement relating to a filed financing statement describing the Collateral; 
 (xii) There is a material adverse
change in the Debtor’s financial condition and operations as determined in the commercially reasonable judgment of Secured Party; provided, however, that such a change will not be deemed to have occurred solely because of the occurrence of any
of the following individual events: (a) negative responses from regulatory agencies; (b) negative clinical trial results; (c) a low cash position; (d) fluctuations in revenues; or (e) continuing losses from operations;
provided, further, however, that (I) the occurrence of any of (a), (b) or (c) may form the basis on which the Secured Party reasonably determines that a material adverse change has occurred if any such event occurs in combination with
one or more of the others of (a), (b) and (c) and (II) the occurrence of any of (a), (b), and (c), may form the basis on which the Secured Party reasonably determines that a material adverse change has occurred if any such event occurs
with other adverse changes in Debtor’s financial condition; 
 (xiii) Any Guarantor revokes or attempts to revoke its guaranty of any of
the Indebtedness or fails to observe or perform any covenant, condition or agreement to be performed under any guaranty or other related document to which it is a party; 
 (xiv) Debtor defaults under any other obligation in excess of $100,000 for (A) borrowed money, (B) the deferred purchase price of property or (C) payments due under any lease agreement; 
  

 - 10 - 

 (xv) At any time during the term of this Agreement Debtor experiences a change in control such that any
person or entity acquires either more than 50% of the voting stock of Debtor or sells all or substantially all of its assets, in either case, without Secured Party’s prior written consent (a “Change in Control”). Notwithstanding the
foregoing, it shall not be an Event of Default and no prior written consent shall be required if there is a change in Control in which Secured Party acquires more than 50% of the voting stock of Debtor; or 
 (xvi) Debtor or any Guarantor or other obligor for any of the Indebtedness sells, licenses, sublicenses, transfers, assigns, mortgages, pledges, leases,
grants a security interest in or encumbers any or all of Debtor’s Intellectual Property now existing or hereafter acquired. “Intellectual Property” shall, with respect to Debtor or any Subsidiary, be used as defined in
Collateral Schedule No. 2. For purposes of this paragraph (xvi) only, licenses, sublicenses or marketing rights granted by the Debtor of its Intellectual Property pursuant to Section 2(m) shall be excluded from the definition of
Intellectual Property. Debtor shall provide Secured Party with a listing of licenses, sublicenses and marketing rights granted to third parties within ten (10) days of receipt of written request. 
 (b) Upon the occurrence and during the continuance of any Event of Default (other than a default under Section 7(a)(viii) or (x) or if Debtor
shall have acted in a fraudulent manner or shall have committed an act of fraud), the Secured Party, at its option, may declare any or all of the Indebtedness to be immediately due and payable, without demand or notice to Debtor or any Guarantor. If
Borrower is in default under Section 7(a)(viii) or (x) or if Debtor shall have acted in a fraudulent manner or shall have committed an act of fraud, then the Indebtedness shall immediately become due and payable, without demand or notice
to Debtor or any Guarantor. The accelerated obligations and liabilities shall bear interest (both before and after any judgment) until paid in full at the lower of eighteen percent (18%) per annum or the maximum rate not prohibited by
applicable law. 
 (c) Upon the occurrence and during the continuance of any Event of Default or if Debtor shall have acted in a fraudulent
manner or shall have committed an act of fraud, Secured Party shall have all of the rights and remedies of a Secured Party under the Uniform Commercial Code and under any other applicable law. Without limiting the foregoing, Secured Party shall have
the right to (i) notify any account debtor of Debtor or any obligor on any instrument which constitutes part of the Collateral to make payment to the Secured Party, (ii) with or without legal process, enter any premises where the
Collateral may be and take possession of and remove the Collateral from the premises or store it on the premises, (iii) sell the Collateral at public or private sale, in whole or in part, and have the right to bid and purchase at said sale or
(iv) lease or otherwise dispose of all or part of the Collateral, applying proceeds from such disposition to the obligations then in default. If requested by Secured Party, Debtor shall promptly assemble the Collateral and make it available to
Secured Party at a place to be designated by Secured Party which is reasonably convenient to both parties. Secured Party may also render any or all of the Collateral unusable at the Debtor’s premises and may dispose of such Collateral on such
premises without liability for rent or costs. Any notice that Secured Party is required to give to Debtor under the Uniform Commercial Code of the time and place of any public sale or the time after which any private sale or other intended
disposition of the Collateral is to be made shall be deemed to constitute reasonable notice if such notice is given to the last known address of Debtor at least ten (10) days prior to such action. 
  

 - 11 - 

 (d) Proceeds from any sale or lease or other disposition shall be applied: first, to all costs of
repossession, storage, and disposition including without limitation attorneys’, appraisers’, and auctioneers’ fees; second, to discharge the obligations then in default; third, to discharge any other Indebtedness of Debtor to Secured
Party, whether as obligor, endorser, guarantor, surety or indemnitor; fourth, to reasonable, out-of-pocket expenses incurred in paying or settling liens and claims against the Collateral; and lastly, to Debtor, if there exists any surplus. Debtor
shall remain fully liable for any deficiency. 
 (e) Debtor agrees to pay all reasonable attorneys’ fees and other costs incurred by
Secured Party (including without limitation the allocated cost of in-house counsel) in connection with the enforcement, assertion, defense or preservation of Secured Party’s rights and remedies under this Agreement, or if prohibited by law,
such lesser sum as may be permitted. Debtor further agrees that such fees and costs shall constitute Indebtedness. 
 (f) Secured
Party’s rights and remedies under this Agreement or otherwise arising are cumulative and may be exercised singularly or concurrently. Neither the failure nor any delay on the part of the Secured Party to exercise any right, power or privilege
under this Agreement shall operate as a waiver, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise of that or any other right, power or privilege. SECURED PARTY SHALL NOT BE DEEMED TO
HAVE WAIVED ANY OF ITS RIGHTS UNDER THIS AGREEMENT OR UNDER ANY OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY DEBTOR UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY SECURED PARTY. A waiver on any one occasion shall not be construed as a
bar to or waiver of any right or remedy on any future occasion. 
 (g) DEBTOR AND SECURED PARTY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT MATTER OF THIS
TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN DEBTOR AND SECURED PARTY. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT. THIS
WAIVER IS IRREVOCABLE. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING. THE WAIVER ALSO SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT, ANY OTHER DEBT DOCUMENTS, OR TO ANY OTHER
DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 
  

	8.	MISCELLANEOUS. 

 (a) This Agreement, any Note and/or
any of the other Debt Documents may be assigned, in whole or in part, by Secured Party without notice to Debtor, and Debtor agrees not to assert against any such assignee, or assignee’s assigns, any defense, set-off, recoupment claim or
counterclaim which Debtor has or may at any time have against Secured Party for any reason whatsoever. 

  

 - 12 - 

 
Debtor agrees that upon receipt of written notice of an assignment from Secured Party, Debtor will pay all amounts payable under any assigned Debt Documents
to such assignee or as instructed by Secured Party. Debtor also agrees to confirm in writing receipt of the notice of assignment as may be reasonably requested by Secured Party or assignee. 
 (b) All notices to be given in connection with this Agreement shall be in writing, shall be addressed to the parties at their respective addresses set
forth in this Agreement (unless and until a different address may be specified in a written notice to the other party), and shall be deemed given (i) on the date of receipt if delivered in hand or by facsimile transmission, (ii) on the
next business day after being sent by express mail and (iii) on the fourth business day after being sent by regular, registered or certified mail. As used herein, the term “business day” shall mean and include any day other than
Saturdays, Sundays, or other days on which commercial banks in New York, New York are required or authorized to be closed. 
 (c) Debtor
agrees to pay all reasonable attorneys’ fees and all other fees, costs and expenses incurred by Secured Party (including, without limitation, the allocated cost of in-house legal counsel) in connection with the preparation, negotiation and
closing of the transactions contemplated in this Agreement and all related documents and schedules and in connection with the continued administration thereof, including, without limitation, any amendments, modifications, consents or waivers thereof
and in connection with the protection, monitoring or preservation of the Collateral, provided, however, that in no event shall such fees and expenses when aggregated with the costs associated with the Purchase Agreement and the documents
contemplated thereunder exceed the $500,000 provided for in Section 11(j) of the Purchase Agreement. Debtor further agrees that such fees and costs shall constitute Indebtedness. 
 (d) Secured Party may correct patent errors and fill in all banks in this Agreement or in any Collateral Schedule consistent with the agreement of the
parties. 
 (e) Time is of the essence of this Agreement. This Agreement shall be binding, jointly and severally, upon all parties described
as the “Debtor” and their respective heirs, executors, representatives, successors and assigns, and shall inure to the benefit of Secured Party, its successors and assigns. 
 (f) This Agreement and its Collateral Schedules constitute the entire agreement between the parties with respect to the subject matter of this Agreement
and supersede all prior understandings (whether written, verbal or implied) with respect to such subject matter. THIS AGREEMENT AND ITS COLLATERAL SCHEDULES SHALL NOT BE CHANGED OR TERMINATED ORALLY OR BY COURSE OF CONDUCT, BUT ONLY BY A WRITING
SIGNED BY BOTH PARTIES. Section headings contained in this Agreement have been included for convenience only, and shall not affect the construction or interpretation of this Agreement. 
 (g) This Agreement shall continue in full force and effect until all of the Indebtedness has been paid in full to Secured Party or its assignee. The
surrender, upon payment or otherwise, of any promissory notes or any of the other documents evidencing any of the Indebtedness shall not affect the right of Secured Party to retain the Collateral for such other Indebtedness as may then exist or as
it 

  

 - 13 - 

 
may be reasonably contemplated will exist in the future. This Agreement shall automatically be reinstated if Secured Party is ever required to return or
restore the payment of all or any portion of the Indebtedness (all as though such payment had never been made). 
 (h) Debtor authorizes
Secured Party to use its name, logo and/or trademark upon prior written consent of the Debtor, which consent shall not be unreasonably withheld, in connection with certain promotional materials that Secured Party may disseminate to the public. The
promotional materials may include, but are not limited to, brochures, video tape, internet website, press releases, advertising in newspaper and/or other periodicals, lucites, and any other materials relating the fact that Secured Party has a
financing relationship with Debtor. Nothing herein obligates Secured Party to use Debtor’s name, logo and/or trademark, in any promotional materials of Secured Party. 
 (i) THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH, THE
INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES OF SUCH STATE), INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, REGARDLESS OF THE LOCATION OF THE COLLATERAL. 
 (j) Debtor shall indemnify Secured Party and its officers, directors, affiliates, employees and agents from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including without limitation reasonable fees and disbursements of counsel and allocated costs of in-house
counsel) which may be imposed upon, incurred by or asserted against Secured Party in any litigation, proceeding or investigation instituted or conducted by any governmental authority or instrumentality or any other person with respect to any aspect
of, or any transaction contemplated by, or referred to in, or any matter related to this Agreement or the Debt Documents, whether or not Secured Party is a party thereto, except to the extent that any of the foregoing arises out of the gross
negligence or willful misconduct of the party being indemnified as determined by a final non-appealable judgment of a court of competent jurisdiction. 
 (k) Notices. All notices to be given in connection with this Agreement shall be in writing, shall be addressed to the parties at their respective addresses set forth in this Agreement (unless and until a
different address may be specified in a written notice to the other party), and shall be deemed given: (i) on the date of receipt if delivered by hand; (ii) on the next business day after being sent by overnight courier service; and
(iii) on the third business day after being sent by regular, registered or certified mail. As used herein, the term “business day” shall mean and include any day other than Saturdays, Sundays, or other days on which commercial banks
