WHEREAS, upon the terms and conditions set forth in this Agreement, each Stockholder proposes to sell to the Purchaser and the Purchaser proposes to purchase from the Stockholders, up to the number of shares of Company Common Stock equal to such Stockholder’s pro rata portion of the Purchased Shares in exchange for the consideration set forth in this Agreement.

NOW, THEREFORE, in consideration of the respective covenants, agreements and representations and warranties set forth in this Agreement, the parties to this Agreement, intending to be legally bound, agree as follows:

ARTICLE I. DESCRIPTION OF TRANSACTION

1.1

Agreement to Purchase and Sell the Purchased Shares. Subject to the terms and conditions in this Agreement, at the Closing, the Stockholders shall sell, assign, transfer and deliver to the Purchaser free and clear of all Liens, and the Purchaser shall purchase and acquire from such Stockholders, such Stockholders’ right title and interest in and to the number of shares of Company Common Stock (rounded up to the nearest whole share) equal to eighty percent (80%) of the Fully Diluted Shares Outstanding as of the Closing Date (the “Purchased Shares”). By executing this Agreement, each Stockholder agrees to sell to Purchaser a minimum of eighty percent (80%) of the Company Common Stock held by such Stockholder and a maximum of one hundred percent (100%) of the Company Common Stock held by such Stockholder, with the exact number of shares to be sold by each Stockholder to be fixed pursuant to the provisions of Section 1.2.

1.2

Determination of Stockholder’s Pro Rata Portion of Purchased Shares. The number of shares of Company Common Stock to be sold by each Stockholder to the Purchaser at the Closing shall be equal to the lesser of (a) all shares of Company Common Stock held by such Stockholder on the Closing Date and (b) that number of shares of Company Common Stock equal to (i) the number of shares of Company Common Stock held by such Stockholder on the Closing Date multiplied by (b) a fraction, the numerator of which shall be the Purchased Shares, and the denominator of which shall be the aggregate number of shares of Company Common Stock held by all of the Stockholders on the Closing Date.

At the Closing, the Purchaser shall deliver to the Escrow Agent: (i) the Closing Cash Consideration; (ii) stock certificates representing shares of Purchaser Common Stock in the name of the Escrow Agent for the benefit of each Stockholder, in each case for such number of shares of Purchaser Common Stock (rounded down to the nearest whole share of Purchaser Common Stock) as is equal to the product of (A) the total number of Closing Shares to be issued by the Purchaser multiplied by (B) each Stockholder’s Consideration Percentage; provided that any such certificates representing the Closing Shares shall, in each case, represent only whole shares of Purchaser Common Stock; and (iii) in lieu of any fractional shares of Purchaser Common Stock that would have otherwise been issued to the Escrow Agent pursuant to subclause (ii), an amount in cash equal to the dollar amount (rounded to the nearest whole cent, with $0.005 or less being rounded down) determined by multiplying the VWAP Per Share Price by the fraction of a share of Purchaser Common Stock that would otherwise have been issued to the Escrow Agent pursuant to subclause (ii) (collectively, the “Escrowed Closing Consideration”).

All unexercised Company Options outstanding as of immediately prior to the Closing shall, as of the Closing, be automatically cancelled and no longer represent the right to acquire Company Common Stock or any other securities of the Purchaser, the Company or any of their respective Affiliates, and all agreements between the Company and such Stockholder relating to such Company Options shall be deemed terminated in their entirety, void and of no further force or effect.

(b)

At or prior to the Closing, the Company shall terminate the Company Stock Option Plan and all other plans, programs or other arrangements pursuant to which any Company Options or other equity securities of the Company have been or may be granted and the provisions of the Company Stock Option Plan and any other such plans, programs or arrangements shall be canceled as of the Closing. Prior to the Closing, the Company shall ensure that all Company Options shall be terminated as of the Closing and that following the Closing no participant in any Company Stock Option Plan or other plans, programs or arrangements shall have any right thereunder to acquire any equity securities of the Company. The Company shall take all necessary actions to effectuate the provisions of this Section 1.5.

1.6

Company Warrants. All Company Warrants outstanding as of immediately prior to the Closing shall remain unchanged and continue to remain outstanding immediately after the Closing.

At the Closing, the Purchaser shall deliver the Escrowed Closing Consideration to an escrow agent agreed upon by the Purchaser and the Company (the “Escrow Agent”), to be held by the Escrow Agent on behalf of the Stockholders and as collateral to secure the rights of the Purchaser pursuant to this Section 1.7 and of the Indemnified Parties under ARTICLE X. The Escrowed Closing Consideration shall be held pursuant to the provisions of an escrow agreement to be entered into among the Purchaser, the Escrow Agent and the Stockholders’ Representative substantially in the form of EXHIBIT B hereto (the “Escrow Agreement”) or in such other form as agreed upon by the Purchaser and the Company.

(b)

Not later than two (2) Business Days prior to the expiration of the period beginning on the Closing Date and ending one hundred eighty (180) days after the Closing Date (the “Escrow Period”), the Company shall deliver to the Purchaser a statement setting forth the Specified Indebtedness Amount as of the expiration of the Escrow Period (the “Specified Indebtedness Statement”). If the Specified Indebtedness Amount as set forth in the Specified Indebtedness Statement

(c)

Thereafter, any of the Escrowed Closing Consideration not previously released by the Escrow Agent as of the expiration of the Escrow Period shall be released by the Escrow Agent to the Stockholders’ Representative, in trust for the Stockholders; provided, however, that in the event Purchaser or any Indemnified Party has made one or more claim(s) under ARTICLE X prior to the end of the Escrow Period, then, in accordance with and subject to the terms and conditions of the Escrow Agreement, the Escrow Period shall continue (and the Escrow Agent will continue to hold the portion of the Escrowed Closing Consideration in escrow as is equal to the aggregate claimed amounts) until the full and final resolution of such claim(s). For purposes of the escrow and the Escrow Agreement, the value of each Closing Share as of a particular date shall be deemed to be equal to the VWAP Per Share Price as of such date. By virtue of the execution of this Agreement or a Joinder Agreement by a Stockholder, without any further act of any Stockholder, such Stockholder shall be deemed to have consented to and approved (A) the use of the Escrowed Closing Consideration as collateral to secure the rights of the Purchaser pursuant to Section 1.7 in the manner set forth herein and in the Escrow Agreement, (B) the use of the Escrowed Closing Consideration as collateral to secure the rights of the Indemnified Parties under ARTICLE X in the manner set forth herein and in the Escrow Agreement, and (C) the appointment of the Stockholders’ Representative as the representative under the Escrow Agreement of the Stockholders under this Agreement and as the attorney-in-fact and agent for and on behalf of such Stockholder.

by written notice from the Purchaser to the Stockholders’ Representative, if there has been a breach of any representation, warranty, covenant or agreement by the Company or the Stockholders, or any such representation or warranty shall become untrue after the date of this Agreement, such that the conditions in Section 6.1 or Section 6.2 would not be satisfied and such breach is not curable or, if curable, is not cured within the earlier of (A) ten (10) days after written notice thereof is given by the Purchaser to the Stockholders’ Representative, and (B) the Expiration Date;

(iii)

by written notice from the Stockholders’ Representative to the Purchaser, if there has been a breach of any representation, warranty, covenant or agreement by the Purchaser, or any such representation or warranty shall become untrue after the date of this Agreement, such that the conditions in Section 7.1 or Section 7.2 would not be satisfied and such breach is not curable or, if curable, is not cured within the earlier of (A) ten (10) days after written notice thereof is given by the Stockholders’ Representative to the Purchaser; and (B) the Expiration Date; or

(iv)

by five (5) days’ prior written notice by the Stockholders’ Representative to the Purchaser or the Purchaser to the Stockholders’ Representative, as the case may be, in the event the Closing has not occurred on or prior to April 30, 2017 (the “Expiration Date”) for any reason other than delay or nonperformance of or breach by the party seeking such termination; provided that the parties may mutually agree, in writing, to extend the Expiration Date.

(b)

In the event of termination of this Agreement pursuant to this ARTICLE IX, this Agreement shall forthwith become void and there shall be no liability on the part of any party to this Agreement or its partners, officers, directors, stockholders, members or other equity holders, except for obligations under Section 5.6 (Public Announcements), Section 12.2 (Fees and Expenses), Section 12.3 (Waiver; Amendment), Section 12.4 (Entire Agreement), Section 12.5 (Execution of Agreement; Counterparts; Electronic Signatures), Section 12.6 (Governing Law; Exclusive Jurisdiction), Section 12.7 (WAIVER OF JURY TRIAL), Section 12.8 (Assignment and Successors), Section 12.10 (Notices), Section 12.11 (Construction; Usage), Section 12.12 (Enforcement of Agreement), Section 12.13 (Severability), Section 12.16 (Schedules and Exhibits) and this Section 9.1, and the definitions used in each of the foregoing sections, including those set forth in EXHIBIT A hereto, all of which shall survive such termination and the Termination Date. Notwithstanding the foregoing, nothing contained in this Agreement shall relieve any party from liability for any breach of this Agreement.

ARTICLE X. INDEMNIFICATION

10.1

Indemnification Obligations of the Stockholders.

(a)

The Stockholders (collectively, the “Indemnifying Parties”), shall, jointly and severally, indemnify the Purchaser (including the Company after the Closing), the officers and directors of the Purchaser, and their respective successors and assigns (other than Persons who were officers, directors, managers, employees, agents, partners, Representatives, successors and assigns of the Company immediately prior to the Closing) (collectively, the “Indemnified Parties”) and save and hold each of them harmless against and pay on behalf of or reimburse such Indemnified Parties as and when incurred for any loss, liability, demand, claim, action, cause of action, cost, damage, deficiency, Tax, penalty, fine or expense, whether or not arising out of third-party claims (including interest, penalties, reasonable attorneys’ fees and expenses and all amounts paid in investigation, defense or settlement of any of the foregoing) (collectively, “Losses”), which any such Indemnified Party may suffer, sustain or become subject to, as a result of, in connection with, arising out of, relating or incidental to or by virtue of:

(i)

any inaccuracy in or breach of any representation or warranty of the Company or the Stockholders set forth in ARTICLE II or any of the Schedules or Exhibits attached to this Agreement, the Company Compliance Certificate or any other Stockholder Related Agreement, whether such representation or warranty is made as of the date of this Agreement or as of the Closing Date (without giving effect to any materiality, Company Material Adverse Effect or other similar qualification contained in such representation or warranty);

(ii)

any non-fulfillment or breach of any covenant, agreement or undertaking made by the Company in this Agreement or any of the Schedules or Exhibits attached to this Agreement;

(iii)

(A) any provision of any Environmental Law and arising out of, or relating to, (x) any act or omission of the Company or any of or its employees, agents or representatives on or prior to the Closing Date, or (y) the ownership, use, control or operation on or prior to the Closing Date of any real property, plant, facility, site, area or property used in the business of the Company (whether currently or previously owned or leased by the Company) arising from any Release of any Materials of Environmental Concern or off-site shipment of any Materials of Environmental Concern at

or from such real property, plant, facility, site, area or property; or (B) mold or any other environmental matter or condition arising on or prior to the Closing Date;

(iv)

any fraud or intentional misrepresentation of the Company with respect to any representation, warranty or covenant of the Company contained in this Agreement, the Company Compliance Certificate or any other Stockholder Related Agreement;

(v)

any inaccuracy in or breach of any representation or warranty set forth in the Purchased Share Certificate;

(vi)

any liability or obligation of the Company for (i) any Taxes incurred in any Tax period beginning after the Closing Date but arising from the settlement or other resolution with any Governmental Body of an asserted Tax liability which relates to any Tax period or portion thereof ending on or before the Closing Date, or (ii) the unpaid Taxes of any Person under Treasury Regulations Section 1.1502-6 (or any similar provision of other federal, provincial, state, local or foreign Law), as a transferee or successor, by Contract or otherwise, in each case whether or not disclosed to the Purchaser in any Exhibits or Schedules attached to this Agreement, the Company Financial Statements or otherwise;

(vii)

any Legal Proceeding brought by one or more stockholders of the Company (individually or derivatively on behalf of the Company) against the Company, any directors or officers of the Company or the Purchaser pertaining to the transactions contemplated by this Agreement or to claims arising out of factual circumstances that existed prior to the Closing; or

(viii)

any Legal Proceedings directly or indirectly relating to any breach, alleged breach, liability or other matter of the type referred to in clauses (i) through (vii) above (including any Legal Proceeding commenced by any Indemnified Party for the purpose of enforcing any of its rights under this Section 10.1).

(b)

Each Stockholder shall, severally and not jointly, indemnify the Indemnified Parties and save and hold each of them harmless against and pay on behalf of or reimburse such Indemnified Parties as and when incurred for any Losses which any such Indemnified Party may suffer, sustain or become subject to, as a result of, in connection with, arising out of, relating or incidental to or by virtue of:

(i)

any inaccuracy in or breach of any representation or warranty of such Stockholder set forth in ARTICLE III, whether such representation or warranty is made as of the date of this Agreement or as of the Closing Date; and

(ii)

any non-fulfillment or breach of any covenant, agreement or undertaking made by such Stockholder in this Agreement or any of the Schedules or Exhibits attached to this Agreement, or in any Stockholder Related Agreement to which such Stockholder is a party.

In the event that the Company suffers, incurs or otherwise becomes subject to any Losses as a result of or in connection with any inaccuracy in or breach or alleged breach of any representation, warranty, covenant or obligation of the Company or the Stockholders or other matter referred to in Section 10.1(a) or Section 10.1(b), then (without limiting any of the rights of the Purchaser as an Indemnified Party) the Purchaser shall also be deemed, by virtue of their ownership of the Company Common Stock, to have suffered, incurred or otherwise become subject to Losses as a result of and in connection with such inaccuracy, breach, alleged breach or other matter.

(d)

The current or former stockholders of the Company shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against the Company in connection with any indemnification obligation or any liability to which such current or former stockholders of the Company may become subject under or in connection with this Agreement or any other agreement or document delivered to the Purchaser in connection with this Agreement.

10.2

Indemnification Procedure.

(a)

Promptly following receipt by an Indemnified Party of notice by a third-party (including any Governmental Body) of any complaint, dispute or claim or the commencement of any audit, investigation, action or proceeding with respect to which such Indemnified Party may be entitled to indemnification pursuant to this Agreement (a “Third-Party Claim”), or upon realization of a Loss by an Indemnified Party for which the Indemnified Party is entitled to indemnification under this ARTICLE X, such Indemnified Party shall provide written notice thereof to the Stockholders’ Representative; provided, however, that the failure to so notify the Stockholders’ Representative shall relieve the Indemnifying Party from liability under this ARTICLE X with respect to such Third-Party Claim only if, and only to the extent that, such failure to so notify the Stockholders’ Representative materially prejudices the rights and defenses otherwise available to the Indemnifying Party with respect to such Third-Party Claim. The Indemnifying Party shall have the right, upon written notice from the Stockholders’ Representative delivered to the Indemnified Party within ten (10) Business Days thereafter assuming full responsibility for any Losses resulting from such Third-Party Claim, to assume the defense of such Third-Party Claim, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of the fees and disbursements of such counsel; provided, however, that the Indemnifying Party shall not have the right to assume the defense of any Third-Party Claim that (i) affects any Intellectual Property Rights that the Company owns or has a right to use in the conduct of its business as currently conducted and as proposed to be conducted by the Company as of the Closing Date, (ii) is asserted directly by or on behalf of any Person that is a supplier or a customer of the Company, the Indemnified Party or their Affiliates, (iii) seeks an injunction or other equitable relief against the Indemnified Party or its Affiliates, (iv) involves a finding of any violation of Law or other wrongdoing by the Indemnified Party, the Company or their Affiliates, (v) relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, or (vi) does not seek only monetary damages and, in the case of this clause (vi), the Indemnified Party reasonably believes an adverse determination with respect to the Third-Party Claim would be detrimental to or materially injure the reputation or future business prospects of the Indemnified Party. In the event, however, that the Indemnifying Party declines or fails to assume the defense of such Third-Party Claim on the terms of this Section 10.2(a) or to employ counsel reasonably satisfactory to the Indemnified Party, in either case within such ten (10) Business Day period, or thereafter defaults in continuing to defend the Indemnified Party, then any Losses shall include the reasonable fees and disbursements of counsel for the Indemnified Party as incurred. In addition, Losses shall include, as incurred, the reasonable fees and disbursements of counsel for the Indemnified Party: (A) that are incurred prior to the date the Indemnifying Party effectively assumes control of such defense, (B) if the Indemnified Party employs separate counsel due to the Indemnified Party being advised by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnified Party and the Indemnifying Party, (C) if the Indemnified Party employs separate counsel because there are one or more legal or equitable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party, or (D) if the Indemnified Party employs separate counsel because such audit, investigation, action or proceeding involves, or could have a material effect on, any matter beyond the scope of the indemnification or defense obligations of the Indemnifying Party.

(b)

In any Third-Party Claim for which indemnification is being sought under this ARTICLE X, the Indemnified Party or the Indemnifying Party, whichever is not assuming the defense of

such Third-Party Claim, shall have the right to participate in such matter and to retain its own counsel at such party’s own expense. The Indemnifying Party or the Indemnified Party (as the case may be) shall at all times use reasonable efforts to keep the Stockholders’ Representative or Indemnified Party (as the case may be) reasonably apprised of the status of the defense of any matter, the defense of which it is maintaining, and to cooperate in good faith with the other party with respect to the defense of any such matter.

(c)

No Indemnified Party may settle or compromise any Third-Party Claim or consent to the entry of any judgment with respect to which indemnification is being sought under this ARTICLE X without the prior written consent of the Stockholders’ Representative (which may not be unreasonably withheld, conditioned or delayed), unless (i) the Indemnifying Party fails to assume and maintain diligently the defense of such Third-Party Claim pursuant to Section 10.2(a) or fails to reimburse the Indemnified Party within 30 days for expenses incurred by the Indemnified Party in defending itself against any Third-Party Claim in the circumstance where the Indemnifying Party fails to assume the defense of the Indemnified Party or as required under the last sentence of Section 10.2(a) or, having assumed the defense, thereafter defaults in pursuing such defense, or (ii) such settlement, compromise or consent includes an unconditional release of the Indemnifying Party and its officers, directors, employees and Affiliates from all liability arising out of, or related to, such Third-Party Claim without further actual or potential monetary liability to the Indemnifying Party. An Indemnifying Party may not, without the prior written consent of the Indemnified Party, settle or compromise any Third-Party Claim or consent to the entry of any judgment with respect to which indemnification is being sought under this ARTICLE X unless such settlement, compromise or consent (A) includes an unconditional release of the Indemnified Party and its officers, directors, employees and Affiliates from all liability arising out of, or related to, such Third-Party Claim, (B) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnified Party, and (C) does not contain any equitable order, judgment or term that in any manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s Affiliates.

(d)

In the event an Indemnified Party claims a right to payment pursuant to this Agreement with respect to any Loss or other matter not involving a Third-Party Claim (a “Direct Claim”), such Indemnified Party shall send written notice of such claim to the Stockholders’ Representative (a “Notice of Claim”). Such Notice of Claim shall specify the basis for such Direct Claim. The failure by any Indemnified Party to so notify the Stockholders’ Representative shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party with respect to any Direct Claim made pursuant to this Section 10.2(d), it being understood that Notices of Claim in respect of a breach of a representation or warranty must be delivered prior to the expiration of the survival period for such representation or warranty under Section 10.3. In the event the Stockholders’ Representative does not notify the Indemnified Party within ten (10) Business Days following its receipt of such Notice of Claim that the Stockholders’ Representative disputes the Indemnifying Parties’ liability to the Indemnified Party under this ARTICLE X or the amount thereof, the Direct Claim specified by the Indemnified Party in such Notice of Claim shall be conclusively deemed a liability of the Indemnifying Party under this ARTICLE X. In the event the Stockholders’ Representative has timely disputed its liability with respect to such Direct Claim as provided in this Section 10.2(d), as promptly as reasonably practicable, such Indemnified Party and the Stockholders’ Representative shall establish the merits and amount of such Direct Claim (by mutual agreement, litigation or otherwise) and, within five (5) Business Days following the final determination of the merits and amount of such Direct Claim, the Indemnifying Party shall pay to the Indemnified Party in accordance with the offset mechanism pursuant to Section 10.5 an amount equal to such Direct Claim as determined pursuant to this Section 10.2(d).

10.3

Survival Period. The representations, warranties and covenants made by the Company and the Stockholders in this Agreement and the Purchased Share Certificate shall not be extinguished by

the Closing, but shall survive the Closing for, and all claims for indemnification in connection therewith shall be asserted not later than, twelve (12) months following the Closing Date; provided, however, that (a) each of the Fundamental Representations shall survive the Closing without limitation as to time, and the period during which a claim for indemnification may be asserted in connection therewith shall continue indefinitely; (b) each of the representations and warranties contained in Section 2.12 (Intellectual Property) and Section 2.15 (Environmental Matters), shall survive the Closing until, and all claims for indemnification in connection therewith shall be asserted not later than 60 days following, the expiration of any statute of limitations applicable to the rights of any Person to bring any claim with respect to such matters; and (c) each of the representations and warranties contained in Section 2.9 (Taxes) shall survive until, and all claims for indemnification in connection therewith shall be asserted not later than the later to occur of: (i) the 180th day following the end of the period, if any, during which an assessment, reassessment or other form of document assessing liability for Taxes in respect of any taxation year to which these representations and warranties extend could be issued to the Company, and (ii) 60 days following the expiration of any statute of limitations applicable to the rights of any Person to bring any claim with respect to such matters. Notwithstanding the foregoing, if, prior to the close of business on the last day a claim for indemnification may be asserted under this ARTICLE X, the Stockholders’ Representative shall have been properly notified of a claim for indemnity under this ARTICLE X and such claim shall not have been finally resolved or disposed of as of such date, such claim shall continue to survive and shall remain a basis for indemnity under this ARTICLE X until such claim is finally resolved or disposed of in accordance with the terms of this Agreement. All representations, warranties and covenants made by the Purchaser shall continue in accordance with their respective terms. Subject at all times to the limitations set forth in this ARTICLE X, the covenants and agreements of the parties pursuant to this ARTICLE X shall survive without limitation as to time, and the period during which a claim for indemnification may be asserted in connection therewith shall continue indefinitely, subject to applicable statutes of limitations.

10.4

Investigations. The respective representations and warranties of the parties contained in this Agreement or any certificate or other document delivered by any party at or prior to the Closing and the rights to indemnification set forth in this ARTICLE X shall not be deemed waived or otherwise affected by any investigation made, or Knowledge acquired, by any Person.

10.5

Offset Against Closing Shares and Future Product Payments. Notwithstanding anything in this Agreement to the contrary, in the event any Indemnified Party shall suffer any Losses for which such Indemnified Party is entitled to indemnification under this ARTICLE X, such Indemnified Party shall be entitled to recover such Losses by offsetting such Losses against the Escrowed Closing Consideration up until it is released pursuant to Section 1.7(c) and the Escrow Agreement or until the Escrowed Closing Consideration is wholly exhausted and, thereafter, any remaining portion of such Losses shall be satisfied by the Indemnifying Party solely by offsetting such Losses against any Future Product Payments that have yet to be paid and are otherwise payable by the Purchaser or the Company to the Indemnifying Party. In no event shall the aggregate amount of the indemnification obligation of the Indemnifying Parties pursuant to this ARTICLE X exceed the sum of the Escrowed Closing Consideration and the Future Product Payments.

10.6

Set-Off. The Purchaser shall be entitled to set-off any amount or right it may be entitled to pursuant to this Agreement against any amount, right or obligations owed to any Stockholder under this Agreement or any Stockholder Related Agreement.

10.7

Characterization of Indemnification Payments. The Purchaser and the Stockholders agree to treat any payment made under this ARTICLE X as an adjustment to the Escrowed Closing Consideration.

ARTICLE XI. STOCKHOLDERS’ REPRESENTATIVE

11.1

Stockholders’ Representative.

(a)

Each of the Stockholders, by such Stockholder’s execution of this Agreement or a Joinder Agreement, hereby irrevocably appoints the Stockholders’ Representative as agent and attorney in fact for the Company and such Stockholder, and authorizes the Stockholders’ Representative (i) to take all action necessary to consummate the transactions contemplated by this Agreement and the Escrow Agreement, or the defense and/or settlement of any claims for which such Stockholder may be required to indemnify the Purchaser or any other Indemnified Party pursuant to ARTICLE X, (ii) to give and receive all notices required to be given under this Agreement, the Escrow Agreement or the Stockholder Related Agreements, (iii) to authorize delivery to the Purchaser of the Escrowed Closing Consideration or the Future Product Payments to the extent necessary for the Purchaser to exercise its rights under Section 1.7 or ARTICLE X, (iv) to make decisions on behalf of the Company and such Stockholder and take any and all additional action as is contemplated to be taken by or on behalf of such Stockholder by the terms of this Agreement or the Escrow Agreement, including, without limitation regarding (A) indemnification claims, Direct Claims, Third-Party Claims and Notices of Claims, (B) amendments to this Agreement, the Escrow Agreement or the Stockholder Related Agreements, and (C) the Future Product Payments.

(b)

All decisions and actions by the Stockholders’ Representative, including without limitation (i) any agreement between the Stockholders’ Representative and the Purchaser relating to the defense or settlement of any claims for which the Stockholders may be required to indemnify the Purchaser pursuant to ARTICLE X, and (ii) any agreement between the Stockholders’ Representative and the Purchaser relating to the Escrow Agreement or the determination of the Specified Indebtedness Amount under Section 1.7 or any other matter relating to ARTICLE I or the Future Product Payments, shall be binding upon all of the Stockholders, and no Stockholder shall have the right to object, dissent, protest or otherwise contest the same.

(c)

The Stockholders’ Representative shall not have any liability to any of the parties to this Agreement or to the Stockholders for any act done or omitted pursuant to this Agreement as the Stockholders’ Representative while acting in good faith, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Stockholders shall severally indemnify the Stockholders’ Representative and hold the Stockholders’ Representative harmless against any loss, liability or expense incurred without fraud or bad faith on the part of the Stockholders’ Representative and arising out of or in connection with the acceptance or administration of the Stockholders’ Representative’s duties under this Agreement.

(e)

Each of the Stockholders, by such Stockholder’s execution of this Agreement or a Joinder Agreement, agrees, in addition to the foregoing, that:

(i)

the Purchaser shall be entitled to rely conclusively on the instructions and decisions of the Stockholders’ Representative as to (A) the settlement of any claims for indemnification by the Purchaser pursuant to ARTICLE X, (B) actions taken in respect of indemnification claims, Direct Claims, Third-Party Claims, Notices of Claims, the Specified Indebtedness Amount, and the Future Product Payments, and (C) any other actions required or permitted to be taken by the Stockholders’ Representative under this Agreement, the Escrow Agreement and any Stockholder

Related Agreement, and no Stockholder shall have any cause of action against the Purchaser for any action taken by the Purchaser in reliance upon the instructions or decisions of the Stockholders’ Representative;

(ii)

all actions, decisions and instructions of the Stockholders’ Representative shall be conclusive and binding upon the Company and all of the Stockholders and no Stockholder shall have any cause of action against the Stockholders’ Representative for any action taken, decision made or instruction given by the Stockholders’ Representative under this Agreement or the Escrow Agreement except for fraud or willful misconduct by the Stockholders’ Representative in connection with the matters described in this ARTICLE XI; and

(iii)

the provisions of this ARTICLE XI are independent and severable, are irrevocable and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any Stockholder may have in connection with the transactions contemplated by this Agreement, the Escrow Agreement and the Stockholder Related Agreements.

(f)

The provisions of this ARTICLE XI shall be binding upon the executors, heirs, legal Representatives, personal Representatives, successor trustees and successors of each Stockholder, and any reference in this Agreement or the Escrow Agreement to a Stockholder or the Stockholders shall mean and include the successors to the rights of the Stockholders under this Agreement, whether pursuant to testamentary disposition, the laws of descent and distribution or otherwise.

A waiver by any party to this Agreement of the performance of any act shall not constitute a waiver of the performance of any other act or an identical act required to be performed at a later time. Prior to the Closing, this Agreement may not be amended, modified or supplemented except by written agreement among the Purchaser, the Company and the Stockholders’ Representative.

This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which, when taken together, shall constitute one and the same instrument, and shall become effective when counterparts have been signed by each of the parties to this Agreement and delivered to the other parties to this Agreement; it being understood that all parties to this Agreement need not sign the same counterparts.

(b)

This Agreement and any amendments to this Agreement may be executed in one or more counterparts, each of which shall be enforceable against the parties to this Agreement that execute such counterparts, and all of which together shall constitute one and the same instrument.

This Agreement and the relationship of the parties hereto shall be governed by and construed in accordance with the internal laws (and not the law of conflicts) of the State of Delaware.

Each of the parties hereto consents to the jurisdiction of such court (and of the appropriate appellate courts therefrom) in any such suit, action, or proceeding and irrevocably agrees not to commence any litigation relating thereto except in such court, and each further waives any objection to the laying of venue of any such litigation in such court and agrees not to plead or claim in such court that such litigation brought therein has been brought in an inconvenient forum. Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 12.10. Nothing in this Section 12.6, however, shall affect the right of any Person to serve legal process in any other manner permitted by law.

12.8

Assignment and Successors. No party to this Agreement may assign any of its rights or delegate any of its obligations under this Agreement without the prior written consent of the other parties to this Agreement. Subject to the preceding sentence, this Agreement shall apply to, be binding in all respects upon and inure to the benefit of the successors and permitted assigns of the parties to this Agreement. Any Stockholder Entity may dissolve after execution of this Agreement and assign its rights and obligations under this Agreement to its partners, members or stockholders; provided, however, that no

such dissolution shall be permitted unless each proposed assignee (i) executes and delivers a Joinder Agreement and becomes a party to this Agreement, and (ii) executes and delivers all documents required by the Stockholders under this Agreement, including the Stockholders’ Agreement and any Stockholder Related Agreements.

12.9

By 5:00 p.m. Eastern Time on the tenth day, or if such day is not a Business Day, by 10:00 a.m. Eastern Time on the first Business Day following the tenth day, after the Escrow Agent’s receipt of a Claim Notice, an Authorized Representative of the Stockholders’ Representative shall deliver to the Escrow Agent, with a copy to the Purchaser, a written response (the “Response Notice”) in which the Stockholders’ Representative: (i) agrees that an amount equal to the full Claimed Amount may be released from the Escrow Fund to the Indemnified Party; (ii) agrees that an amount equal to part, but not all, of the Claimed Amount may be released from the Escrow Fund to the Indemnified Party; or (iii) indicates that no part of the Escrow Fund may be released from the Escrow Fund to the Indemnified Party in respect of the Claimed Amount. Any part of the Claimed Amount that is not agreed to be released to the Indemnified Party pursuant to the Response Notice, which determination shall be made in good faith by the Stockholders’ Representative, shall be the “Contested Amount.” If a Response Notice is not received by 5:00 p.m. Eastern Time on the last day of such 10-day period, or if such day is not a Business Day, by 10:00 a.m. Eastern Time on the first Business Day following the tenth day, then the Stockholders’ Representative shall be conclusively deemed to have agreed that an amount equal to the full Claimed Amount (plus a pro rata portion of the interest and investment income deposited in the Escrow Fund from the date hereof which is attributable to such Claimed Amount, if any) shall be released to the Purchaser from the Escrow Fund, using the delivery instructions in Section 13(b).

(d)

If the Stockholders’ Representative delivers a Response Notice agreeing that an amount equal to the full Claimed Amount may be released from the Escrow Fund to the Purchaser, or if the Stockholders’ Representative does not deliver a Response Notice on a timely basis in accordance with Section 4(c), the Escrow

Agent shall within five (5) Business Days following the receipt of such Response Notice (or, if the Escrow Agent has not received a Response Notice within the required 10-day period, within five (5) Business Days following the expiration of the ten (10)-day period referred to in Section 4(c)), deliver to the Purchaser an amount equal to the full Claimed Amount (plus a pro rata portion of the interest and investment income deposited in the Escrow Fund from the date hereof which is attributable to the full Claimed Amount, if any), using the delivery instructions in Section 13(b).

(e)

If an Authorized Representative of the Stockholders’ Representative delivers a timely Response Notice agreeing that an amount equal to less than the full Claimed Amount may be released from the Escrow Fund to the Purchaser (the “Agreed Amount”), the Escrow Agent shall, within five (5) Business Days following the receipt of such Response Notice, deliver to the Purchaser an amount equal to the Agreed Amount (plus a pro rata portion of the interest and investment income deposited in the Escrow Fund from the date hereof which is attributable to such Agreed Amount, if any), using the delivery instructions in Section 13(b). Such delivery shall not be deemed to be made in full satisfaction of the claim described in such Claim Notice and the remaining amount (not taking into account any interest or earnings earned on the Agreed Amount and distributed to the Indemnified Party pursuant to the preceding sentence, if any) shall be the Contested Amount as provided in Section 4(c).

(f)

If an Authorized Representative of the Stockholders’ Representative delivers a timely Response Notice indicating that there is a Contested Amount, without limiting the Escrow Agent’s obligations under Section 4(e), the Stockholders’ Representative and the Purchaser shall attempt in good faith to resolve the dispute related to the Contested Amount within ten (10) Business Days of the Purchaser’s receipt of such Response Notice (the “Negotiation Period”). If the Purchaser and the Stockholders’ Representative resolve such dispute, such written resolution shall be binding on the Stockholders’ Representative, each of the Stockholders and the Indemnified Party, and a settlement agreement shall be signed by an Authorized Representative of the Purchaser (on behalf of such Indemnified Party) and the Stockholders’ Representative and sent to the Escrow Agent, which shall, within three Business Days of receipt thereof, if applicable, release an amount of Escrowed Closing Consideration in accordance with such settlement agreement (plus a pro rata portion of the interest and investment income deposited in the Escrow Fund from the date hereof which is attributable to such amount, if any, to be released pursuant to such settlement agreement, if any), using the delivery instructions in Section 13(b). Unless and until the Escrow Agent receives joint written notice that any such dispute has been resolved by the Purchaser and the Stockholders’ Representative, the Escrow Agent may assume without inquiry that such dispute has not been resolved. If the Purchaser and the Stockholders’ Representative fail to reach agreement by the end of the Negotiation Period, each Party shall be entitled to its legal remedies in accordance with this Agreement and the Stock Purchase Agreement and the Escrow Agent shall continue to hold such Contested Amount in escrow in accordance with the terms of this Agreement.

(g)

The Escrow Agent shall deliver to the applicable Party an amount of Escrowed Closing Consideration from the Escrow Fund in connection with any Contested Amount within five (5) Business Days after the delivery to it of: (i) a copy of a settlement agreement executed by an Authorized Representative of the Purchaser and the Stockholders’ Representative setting forth instructions to the Escrow Agent as to the amount of Escrowed Closing Consideration, if any, to be released from the Escrow Fund with respect to such Contested Amount; or (ii) a certified copy of a final and non-appealable binding order, decree or judgment issued or rendered by a court of competent jurisdiction or a certified copy of a final, non-appealable arbitration award from the prevailing Party along with a certification from its counsel attesting to the finality and binding nature of the final order or arbitration award, that instructs the Escrow Agent as to the resulting disbursement of the Escrow Fund specified therein, in each case, plus any interest or earnings earned on any portion of the amount to be distributed, if any, using the delivery instructions in Section 13(b). The Escrow Agent shall be entitled conclusively to rely upon any such certification and instruction and shall have no responsibility to review the order, decree or judgment to which such certification and instruction refers or to make any determination as to whether such order, decree or judgment is final.

(h)

At any time that a payment, distribution or holdback is required to be made pursuant to this Agreement and written instructions have been provided to the Escrow Agent, such payment, distribution or holdback shall be made as directed by the Stockholders’ Representative from the Escrow Fund with an aggregate value equal to the amount of such payment, distribution or holdback (it being understood that the Stockholders’ Representative may direct that such amount be released to the Transfer Agent for disbursement to the Stockholders in accordance with the payment instructions provided by the Stockholders’ Representative, and the Purchaser agrees to assist the Stockholders’ Representative in coordinating such disbursement with the Transfer Agent). For purposes of the

Stockholders’ Representative, the respective interests of the Stockholders are set forth on Exhibit A hereto, and, as to each Stockholder, the respective Consideration Percentage for such Stockholder are set forth in Exhibit A hereto. Each Stockholder shall be entitled to that portion of the Escrow Fund as is equal to the total value of the Escrow Fund multiplied by such Stockholder’s Consideration Percentage. For purposes of determining the value of each Escrow Share as of a particular date, each Escrow Share shall be valued at the average of the daily volume weighted average price of the Purchaser Common Stock for the twenty (20) trading days then preceding the determination date, as reported by Bloomberg L.P. on the determination date (the “VWAP Per Share Price”). The Escrow Agent shall not be responsible for any calculations or valuations.

(i)

Notwithstanding anything to the contrary herein, any release of funds by the Escrow Agent to an Indemnified Party pursuant to this Section 4 shall be made to the Purchaser (for distribution to the Indemnified Party).

(j)

The Escrow Agent may rely conclusively on any Claim Notice it receives hereunder. The Escrow Agent shall have no responsibility to determine whether any Claim Notice satisfies the conditions set forth in the Stock Purchase Agreement for making an indemnification claim, including whether there is a basis for making a claim, whether the claim is set forth in sufficient detail, or that a copy of the Claim Notice was sent to or received by the Stockholders’ Representative, or that a Response Notice was sent to or received by the Purchaser or any Indemnified Party.

(k)

The Purchaser and the Stockholders’ Representative each agree to deliver Claim Notices and Response Notices to the other Party in the same manner and at the same time as delivery to the Escrow Agent.

(l)

Each of the parties to this Agreement acknowledges and agrees that, after the Closing, the Purchaser shall have authority to settle all claims under this Agreement and the Stock Purchase Agreement on behalf of the Company or any of its Affiliates.

Form of Notices and Instructions.

(a)

Any instructions setting forth, claiming, containing, objecting to, or in any way related to the transfer or distribution of the Escrow Fund (including without limitation, Claim Notices and Response Notices), must be in writing or set forth in a Portable Document Format (“PDF”), executed by the appropriate Party as evidenced by the signatures of the persons or person signing this Agreement or one of their designated persons as set forth in Exhibit C-1 hereto or Exhibit C-2 hereto (each an “Authorized Representative”), and delivered to the Escrow Agent only by confirmed facsimile or attached to an email and only to the fax number or email address set forth in Section 13(b). The Escrow Agent shall not be liable to any Party or other Person for refraining from acting upon any instruction for or related to the transfer or distribution of the Escrow Fund if not delivered to the fax number or email address set forth in Section 13(b).

(b)

All re-registrations of Escrow Shares must be delivered by the Escrow Agent to the Purchaser’s transfer agent (the “Transfer Agent”) with detailed instructions. Currently, _____________________________________, is the Transfer Agent for the Purchaser. The Purchaser will notify the Escrow Agent if the Transfer Agent changes during the term of this Agreement.

(c)

The Parties acknowledge that there are certain security, corruption, transmission error and access availability risks associated with using open networks such as the Internet and the Parties hereby expressly assume such risks.

(d)

The Escrow Agent may conclusively rely upon any written notice, document, instruction or request delivered by the Parties believed by it to be genuine and to have been signed by an Authorized Representative(s), as applicable, without inquiry and without requiring substantiating evidence of any kind and the Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request.

Release of Escrow Fund.

(a)

Except as otherwise provided herein, but in any event subject to Section 3, within five (5) Business Days following the Escrow Fund Release Date, the Escrow Agent shall distribute as jointly directed by the Purchaser and the Stockholders’ Representative the Escrowed Closing Consideration held in the Escrow Fund,

including any Additional Property and any interest earned thereon, not otherwise distributed to the Purchaser or the Indemnified Parties pursuant to Section 4 or retained in the Escrow Fund, using the delivery instructions in Section 13(b) (it being understood that the Purchaser and the Stockholders’ Representative may jointly direct that such amount be released to the Transfer Agent for disbursement to the Stockholders in accordance with the payment instructions provided in such direction, and the Purchaser agrees to assist the Stockholders’ Representative in coordinating such disbursement with the Transfer Agent). Notwithstanding the foregoing, if on or prior to 11:59 p.m. Eastern Time on the Escrow Fund Release Date, the Purchaser has given a Claim Notice on behalf of any Indemnified Party containing a claim which has not been resolved in full prior to such date in accordance with Section 4, the Escrow Agent shall retain and safeguard in the Escrow Fund after the Escrow Fund Release Date an amount of Escrowed Closing Consideration equal to the amount described in each such Claim Notice, up to the full Escrow Fund.

Covenant of the Escrow Agent. The Escrow Agent hereby agrees and covenants with the Parties that it will perform all of its obligations under this Agreement and will not deliver custody or possession of any of the Escrow Fund to anyone except pursuant to the express terms of this Agreement.

Fees and Expenses of the Escrow Agent. The Escrow Agent shall be entitled to receive from time to time fees in accordance with Exhibit D hereto. In accordance with Exhibit D hereto, the Escrow Agent will also be entitled to reimbursement for reasonable and documented out-of-pocket expenses incurred by the Escrow Agent in the performance of its duties hereunder and the execution and delivery of this Agreement. All such fees and expenses shall be deducted from the Escrow Fund.

Limitation of the Escrow Agent’s Liability.

(a)

The Purchaser and the Stockholders’ Representative (solely in its representative capacity on behalf of the Stockholders) agree jointly and severally to indemnify, defend, hold harmless, pay or reimburse the Escrow Agent and its affiliates and their respective successors, assigns, directors, agents and employees (the “Escrow Agent Indemnitees”) from and against any and all losses and any other expenses, fees or charges of any character or nature, including, without limitation, attorney’s fees and expenses, which any Escrow Agent Indemnitee may incur or with which it may be threatened by reason of acting as or on behalf of Escrow Agent under this Agreement or arising out of or in connection with (i) the Escrow Agent’s performance of this Agreement, except to the extent that such losses are determined by a court of competent jurisdiction through a final order to have been caused by the gross negligence or willful misconduct of such Escrow Agent Indemnitee; and (ii) the Escrow Agent having followed any instructions or directions, whether joint or singular, from the Stockholders’ Representative or the Purchaser received in accordance with this Agreement. The Purchaser and the Stockholders’ Representative hereby grant the Escrow Agent a lien on, right of set-off against and security interest in the Escrow Fund for the payment of any claim for indemnification, fees, expenses and amounts due to the Escrow Agent or an Escrow Agent Indemnitee. In furtherance of the foregoing, the Escrow Agent is expressly authorized and directed, but shall not be obligated, to charge against and withdraw from the Escrow Fund for its own account or for the account of an Escrow Agent Indemnitee any amounts due to the Escrow Agent or to an Escrow Agent Indemnitee under Section 8 or this Section 9. The obligations set forth in this Section 9 shall survive the resignation, replacement or removal of the Escrow Agent or the termination of this Agreement.

(b)

The Escrow Agent shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that the Escrow Agent’s gross negligence or willful misconduct are determined by a court of competent jurisdiction through a final order to have been the cause of any direct loss to either Party. The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through its agents, representatives, attorneys, custodians and/or nominees. In the event the Escrow Agent shall be uncertain, or believes there is some ambiguity, as to its duties or rights hereunder, or receives instructions, claims or demands from any Party which, in the Escrow Agent’s judgment, conflict with the provisions of this Agreement, or if the Escrow Agent receives conflicting instructions from the Parties, the Escrow Agent shall be entitled either to (i) refrain from taking any action until it shall be given either (A) a joint written direction executed by Authorized Representatives of the Parties which eliminates such conflict, or (B) a court order issued by a court of competent jurisdiction (it being understood that the Escrow Agent shall be entitled conclusively to rely and act upon any such court order and shall have no obligation to determine whether any such court order is final) or by a final court order, or (ii) file an action in interpleader. Anything in this Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever (including

but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

(c)

The Parties hereby acknowledge and agree that the value of the Escrow Shares as set forth in Section 4(h) has been negotiated and agreed between the Parties and that the Escrow Agent shall not be liable or responsible for any diminution in value, or fluctuation in value, with respect to the Escrow Shares due to any decrease or increase (or any subsequent decrease or increase) in the fair market value of the Purchaser Common Stock following the date of this Agreement.

10.

Termination. The terms of this Agreement shall terminate upon the release by the Escrow Agent of the entire Escrow Fund in accordance with this Agreement; provided, however, that if on or prior to the Escrow Fund Release Date, the Escrow Agent has received from the Purchaser a Claim Notice in accordance with the terms and requirements set forth in Section 4 and elsewhere in this Agreement, setting forth a claim that has not been fully resolved by the Escrow Fund Release Date, then this Agreement shall continue in full force and effect with respect to that portion of the Escrow Fund necessary to resolve each such unresolved claim for the purpose of resolving such unresolved claim until such claim has been fully resolved and the retained amount released in accordance with this Agreement. Notwithstanding the foregoing, in no event shall this Agreement cease to remain in full force and effect until such time as all assets deposited hereunder have been distributed by the Escrow Agent per the terms of this Agreement.

11.

Successor Escrow Agent. In the event the Escrow Agent becomes unavailable or unwilling to continue as escrow agent under this Agreement, the Escrow Agent may resign and be discharged from its duties and obligations hereunder by giving its written resignation to the Parties upon 30 days’ prior written notice to the Parties. In addition, the Escrow Agent may be removed at any time, with or without cause, upon 30 days’ prior written notice delivered to the Escrow Agent and executed by both the Purchaser and the Stockholders’ Representative. Such resignation or removal shall take effect not less than 30 days after notice is given to all Parties and the Escrow Agent. In such event, the Purchaser may appoint, with the consent of the Stockholders’ Representative, which consent shall not be unreasonably withheld, conditioned or delayed, a successor Escrow Agent, which shall be a commercial bank, trust company or other financial institution with a combined capital and surplus in excess of $100,000,000 (unless otherwise agreed by the Parties in writing), that will be an unrelated third party with respect to each of the Purchaser and the Stockholders’ Representative. If the Purchaser fails to appoint a successor Escrow Agent within 15 days after receiving the Escrow Agent’s written resignation, the Escrow Agent shall have the right to apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent or appoint a successor Escrow Agent of its own choice. Any appointment of a successor Escrow Agent shall be binding upon the Purchaser, each of the Stockholders and the Stockholders’ Representative, and no appointed successor Escrow Agent shall be deemed to be an agent of the Escrow Agent. The successor Escrow Agent shall execute and deliver to the Escrow Agent an instrument accepting such appointment on the terms and conditions contained in this Agreement, and the successor Escrow Agent shall, without further acts, be vested with all the estates, property rights, powers and duties of the predecessor Escrow Agent as if originally named as the Escrow Agent herein. The Escrow Agent shall act in accordance with written instructions from the Purchaser and the Stockholders’ Representative as to the transfer of the Escrow Fund to a successor Escrow Agent, at which time the Escrow Agent’s obligations under this Agreement shall cease and terminate. Any entity into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any entity to which all or substantially all the escrow business may be transferred, shall be the Escrow Agent under this Agreement without further act.

12.

Stockholders’ Representative.

(a)

Appointment. As between the Parties, each Stockholder has approved the indemnification and escrow terms set forth in the Stock Purchase Agreement and the appointment of the Stockholders’ Representative to give and receive notices and communications, to authorize delivery to the Purchaser of Escrowed Closing Consideration or Additional Property or to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of and demand arbitration, and comply with orders of courts and awards of arbitrator(s) with respect to claims of the Indemnified Parties hereunder, and to take all actions necessary or appropriate in the reasonable judgment of the Stockholders’ Representative for the accomplishment of the foregoing.

(b)

Successor Stockholders’ Representative. If the Stockholders’ Representative or any successors thereto shall be dissolved or otherwise be unable to fulfill such Stockholders’ Representative’s responsibilities as the agent of the stockholders of the Company, then the Stockholders’ Representative shall, within 10 calendar days after

such event, appoint a successor representative reasonably satisfactory to the Purchaser, subject to such successor representative’s compliance with Patriot Act requirements and the consent of the Escrow Agent. Unless and until the Purchaser and the Escrow Agent shall have received written notice of the appointment of a successor Stockholders’ Representative, the Purchaser and the Escrow Agent shall be entitled to rely on, and shall be fully protected in relying on, the power and authority of the Stockholders’ Representative to act on behalf of the Stockholders.

13.

Miscellaneous.

(a)

Waiver and Amendment. Any agreement on the part of a Party or the Escrow Agent to any extension or waiver of any provision hereof shall be valid only if set forth in an instrument in writing signed on behalf of such Party and the Escrow Agent. A waiver by a Party or the Escrow Agent of the performance of any covenant, agreement, obligation, condition, representation or warranty shall not be construed as a waiver of any other covenant, agreement, obligation, condition, representation or warranty. A waiver by any Party or the Escrow Agent of the performance of any act shall not constitute a waiver of the performance of any other act or an identical act required to be performed at a later time. This Agreement may not be amended, modified, altered or supplemented except by written agreement of the Parties and the Escrow Agent.

(b)

Notices. All notices, requests, claims, demands, consents, waivers and other communications required or permitted by this Agreement shall be in writing, and all instructions to the Escrow Agent shall be executed by an Authorized Representative of the Parties, and shall be deemed given to a Party when (a) delivered to the appropriate address by nationally recognized overnight courier service (costs prepaid); (b) sent by facsimile with confirmation of transmission in each case to the following addresses, or facsimile numbers and marked to the attention of the person (by name or title) designated below (or to such other address, facsimile number, or person as a Party may designate by notice to the other Parties); or (c) sent by a PDF attached to an email to the email address set forth in this Section 13(b):

Notwithstanding anything to the contrary in this Agreement, any instructions setting forth, claiming, containing, objecting to, or in any way related to the transfer or distribution of the Escrow Fund, must be in writing executed by the appropriate Party or Parties and delivered to the Escrow Agent only by confirmed facsimile or as a PDF attached to an email and only to the fax number or email address set forth above. No instruction for or related to the transfer or distribution of the Escrow Fund shall be deemed delivered and effective unless the Escrow Agent actually shall have received it on a Business Day by facsimile or as a PDF attached to an email to the fax number or email address set forth above and as evidenced by a confirmed transmittal to the Party’s or Parties’ transmitting fax

number or email address and the Escrow Agent has been able to satisfy any applicable security procedures as may be required hereunder. The Escrow Agent shall not be liable to any Party or other person for refraining from acting upon any instruction for or related to the transfer or distribution of the Escrow Fund if delivered to any other fax number or email address, including but not limited to a valid email address of any employee of Escrow Agent. The Parties each acknowledge that the Escrow Agent is authorized to use the following funds transfer instructions to disburse any release of Escrowed Closing Consideration, without a verifying call-back as set forth below; provided, however, that Escrow Closing Consideration shall be deemed delivered when delivered to the Transfer Agent as provided in Section 3.

Purchaser – Escrowed Closing Consideration Delivery Instructions:

Stockholders’ Representative – Escrowed Closing Consideration Delivery Instructions:

As directed by the Stockholders’ Representative in connection with any such delivery.

Security Procedure for Funds Transfer. Concurrent with the execution of this Escrow Agreement, the Parties shall deliver to the Escrow Agent authorized signers’ forms in the form of Exhibit C-1 hereto and Exhibit C-2 hereto. The Escrow Agent shall confirm each funds transfer instruction received in the name of Parties by confirming with an authorized individual as evidenced in Exhibit C-1 hereto and Exhibit C-2 hereto. Once delivered to the Escrow Agent, Exhibit C-1 hereto or Exhibit C-2 hereto may be revised or rescinded only in writing signed by an authorized representative of the Party. Such revisions or rescissions shall be effective only after actual receipt and following such period of time as may be necessary to afford the Escrow Agent a reasonable opportunity to act on it. If a revised Exhibit C-1 hereto or Exhibit C-2 hereto or a rescission of an existing Exhibit C-1 hereto or Exhibit C-2 hereto is delivered to the Escrow Agent by an entity that is a successor-in-interest to either party, such document shall be accompanied by additional documentation satisfactory to the Escrow Agent showing that such entity has succeeded to the rights and responsibilities of the Parties. The Parties understand that the Escrow Agent’s inability to receive or confirm funds transfer instructions may result in a delay in accomplishing such funds transfer, and agree that the Escrow Agent shall not be liable for any loss caused by any such delay.

The Parties represent, warrant and covenant that each document, notice, instruction or request provided by such Party to the Escrow Agent shall comply with applicable laws and regulations.

(i)

Waiver of Immunity. To the extent that in any jurisdiction any party to this Agreement may now or hereafter be entitled to claim, for itself or its assets, immunity from suit, execution, attachment (before or after judgment) or other legal process, such party to this Agreement shall not claim, and hereby irrevocably waives, such immunity.

The Parties agree that, for tax reporting purposes, all interest on or other income, if any, attributable to any cash held in the Escrow Fund or any other cash amount held in escrow by the Escrow Agent pursuant to this Agreement shall be allocable and reportable to the Stockholders’ Representative, as income earned from the Escrow Fund by the Stockholders’ Representative whether or not said income has been distributed during such year. The Parties agree to provide the Escrow Agent with certified tax identification numbers by completing, signing and returning a Form W-9 or Form W-8BEN, as applicable, and any other forms and documents that the Escrow Agent may reasonably request (collectively, “Tax Reporting Documentation”) to the Escrow Agent prior to the execution of this Agreement.

The sole tax reporting obligation of the Escrow Agent shall be to file a Form 1099 INT or 1042S (as applicable) with the Internal Revenue Service with respect to interest earnings on cash amounts to the Stockholders’ Representative. The Parties hereby represent to the Escrow Agent that no other tax reporting of any kind is required given the underlying transaction giving rise to this Agreement.

SECTION 3.

DRAG-ALONG RIGHTS.

3.1

Approved Sale. For the purposes of this Section 3, an “Approved Sale” shall mean an Acquisition that is approved by (a) the Board and (b) Heat.

3.2

Actions to be Taken. In the event of an Approved Sale, each of the Stockholders hereby agrees:

(a)

if such transaction requires stockholder approval, with respect to all shares of capital stock of the Company that such Stockholder owns or over which such Stockholder otherwise exercises voting control, to vote (in person, by proxy or by action by written consent, as applicable) all shares of capital stock of the Company in favor of, and adopt, such Approved Sale (together with any related transaction agreement for such Approved Sale and any amendment to the Company’s Certificate of Incorporation, as may be amended or restated from time to time, to be made in connection with such Approved Sale) and to vote in opposition to, and withhold consent from, any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Approved Sale;

(b)

if such transaction is an acquisition of at least a majority of the total outstanding shares of capital stock of the Company (other than for bona fide equity financing purposes) by an unrelated Person, to sell the same proportion of shares of capital stock of the Company beneficially held by such Stockholder as is being sold by Heat to the Person to whom Heat propose to sell its shares of capital stock of the Company on the same terms and conditions as Heat;

(c)

to execute and deliver all related documentation and take such other action in support of the Approved Sale in order to carry out the terms and provisions of this Section 3, including, without limitation, (i) executing and delivering instruments of conveyance and transfer, and any purchase agreement, merger agreement, indemnity agreement, escrow agreement, consent, waiver, governmental filing, stock certificates duly endorsed for transfer (free and clear of impermissible liens, claims and encumbrances) and any similar or related documents related to the Approved Sale, (ii) making the same representations, warranties, covenants, indemnities and agreements as made by Heat in connection with the Approved Sale, and (iii) agreeing to the same terms and conditions to the Approved Sale as those to which Heat agrees;

(d)

not to deposit, and to cause its Affiliates not to deposit, except as provided in this Agreement, any shares of capital stock of the Company owned by such party or Affiliate in a voting trust or subject any such shares of capital stock of the Company to any arrangement or agreement with respect to the voting of such shares of capital stock of the Company, unless specifically requested to do so by Heat in connection with an Approved Sale;

(e)

to affirmatively waive, and otherwise refrain from exercising, any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Approved Sale; and

(f)

if the consideration to be paid in exchange for the shares of capital stock of the Company in an Approved Sale pursuant to this Section 3 includes any securities and due receipt thereof by any Stockholder would require under applicable law (i) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities, or (ii) the provision to any Stockholder of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act, the Company may cause to be paid to such Stockholder in lieu thereof, against surrender of the shares of capital stock of the Company which would have otherwise been sold by such Stockholder, an amount in cash equal to the fair value (as determined in good faith by the Board) of the securities which such Stockholder would otherwise receive as of the date of the issuance of such securities in exchange for the shares of capital stock of the Company.

3.3

Irrevocable Proxy. To secure the Stockholders’ obligations to vote (or provide consent with respect to) or take any other action (including the actions set forth in Section 3.2) with respect to their shares of capital stock of the Company in accordance with this Agreement, each Stockholder hereby appoints the Chairperson of the Board of Directors of Heat, the Chief Executive Officer of Heat or any other Person authorized by the Board of Directors of Heat, or any of them from time to time, as such Stockholder’s true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote (or provide consent with respect to) or take any other action (including the actions set forth in Section 3.2) with respect to all of such Stockholder’s shares of capital stock of the Company subject to this Agreement and to execute all appropriate documents, certificates, agreements and other instruments consistent with this Agreement on behalf of such Stockholder if, and only if, such Stockholder fails to vote (or provide consent with respect to) or take any such action (including the actions set forth in Section 3.2) with respect to all of such Stockholder’s shares of capital stock of the Company or execute such other documents, certificates, agreements and other instruments in accordance with the provisions of this Agreement within three (3) Business Days of the Company’s, Heat’s or any other party’s written request for such Stockholder’s vote, written consent or signature. The proxy and power of attorney granted by each Stockholder pursuant to this Section 3.3 is coupled with an interest and are given to secure the performance of such party’s duties under this Agreement. Each such proxy and power will be irrevocable for the term of this Agreement and it is expressly acknowledged and agreed that the term of such proxy and power may exceed three (3) years. The proxy and power, so long as any party hereto is an individual, will survive the death, incompetency, and disability of such party or any other individual Stockholder, and, so long as any party hereto is an entity, will survive the merger or reorganization of such party or any other entity holding any shares of capital stock of the Company.

3.4

Exceptions. Notwithstanding anything in this Agreement to the contrary, a Stockholder will not be required to comply with Section 3.2 in connection with any proposed Approved Sale unless:

(a)

the Stockholder shall not be liable for the inaccuracy of any representation or warranty made by any other Person in connection with the Approved Sale, other than the Company (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the

Company as well as breach by any stockholder of any identical representations, warranties and covenants provided by all stockholders); and

(b)

the liability for indemnification, if any, of such Stockholder in the Approved Sale and for the inaccuracy of any representations and warranties made by the Company or the Stockholders in connection with such Approved Sale, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any stockholder of any identical representations, warranties and covenants provided by all stockholders), and is pro rata in proportion to, and does not exceed, the amount of consideration paid to such Stockholder in connection with such Approved Sale in its capacity as a holder of shares of capital stock of the Company.

SECTION 4.

CO-SALE RIGHTS.

4.1

Notice of Transfer.

(a)

Other than in connection with a Transfer (as defined below) excluded by Section 4.2, if Heat proposes to Transfer any shares of Common Stock, then Heat shall promptly give written notice (the “Co-Sale Notice”) simultaneously to the Company and to each of the Stockholders at least 30 days prior to the closing of such Transfer. The Notice shall describe in reasonable detail the proposed Transfer, including, without limitation, the number of shares of Common Stock to be transferred, the nature of such Transfer, the consideration to be paid, the proposed closing date of such Transfer, the other material terms and conditions upon which the proposed Transfer is to be made and the name and address of each prospective purchaser or transferee. If the consideration proposed to be paid for the Common Stock in the proposed Transfer is other than cash, the fair market value of the consideration shall be determined in good faith by the Board. The notice shall also state that each Stockholder shall have the right, exercisable upon written notice to Heat with a copy to the Company within 10 days after receipt of the Co-Sale Notice (the “Co-Sale Period”), to participate in such Transfer of Common Stock on the same terms and conditions. Such Co-Sale Notice shall indicate the number of shares of Common Stock, up to that number of shares determined under Section 4.1(c), that such Stockholder wishes to sell under his, her or its right to participate. To the extent one or more of the Stockholders exercise such right of participation in accordance with the terms and conditions set forth below, the number of shares of Common Stock that Heat may sell in the transaction shall be correspondingly reduced.

(b)

For purposes of this Section 4, the term “Transfer” shall include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift, transfer by request, devise, or descent, or other transfer or disposition of any kind, including, but not limited to, transfers to receivers, levying creditors, trustees, or receivers in bankruptcy proceedings or general assignees for the benefit of creditors, whether voluntary or by operation of law, directly or indirectly, of any Common Stock.

(c)

Each Stockholder may sell all or any part of that number of shares equal to the product obtained by multiplying (i) the aggregate number of shares of Common Stock covered by the Co-Sale Notice, by (ii) a fraction, the numerator of which is the number of shares of Common Stock held by such Stockholder at the time of the Co-Sale Notice, and the denominator of which is the total number of shares of Common Stock held by Heat plus the number of shares of Common Stock held by all Stockholders at the time of the Co-Sale Notice.

(d)

Each Stockholder who elects to participate in the Transfer pursuant to this Section 4 (a “Co-Sale Participant”) shall effect its participation in the Transfer by promptly delivering to Heat for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent the number of shares of Common Stock which such Co-Sale Participant elects to sell.

(e)

The stock certificate or certificates that the Co-Sale Participant delivers to Heat pursuant to Section 4.1(d) shall be transferred to the prospective purchaser in consummation of the sale of the Common Stock pursuant to the terms and conditions specified in the Co-Sale Notice, and Heat shall concurrently therewith remit to such Co-Sale Participant that portion of the sale proceeds to which such Co-Sale Participant is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities from a Co-Sale Participant exercising its rights of co-sale hereunder, Heat shall not sell to such prospective purchaser or purchasers any Common Stock unless and until,

simultaneously with such sale, Heat shall purchase such shares or other securities from such Co-Sale Participant on the same terms and conditions specified in the Co-Sale Notice.

(f)

The exercise or non-exercise of the rights of any Stockholder hereunder to participate in one or more Transfers of Common Stock made by Heat shall not adversely affect such Stockholder’s right to participate in subsequent Transfers of Common Stock subject to this Section 4.

(g)

To the extent that the Stockholders do not elect to participate in the sale of the Common Stock subject to the Co-Sale Notice, Heat may, not later than 90 days following delivery to the Stockholders of the Co-Sale Notice, enter into an agreement providing for the closing of the Transfer of such Common Stock covered by the Co-Sale Notice within 30 days of such agreement on terms and conditions not materially more favorable to Heat than those described in the Co-Sale Notice. Any proposed Transfer on terms and conditions materially more favorable to Heat than those described in the Co-Sale Notice, as well as any subsequent proposed Transfer of any of the Common Stock by Heat, shall again be subject to the co-sale rights of the Stockholders and shall require compliance by Heat with the procedures described in this Section 4.

4.2

Exempt Transfers. Notwithstanding the foregoing, the provisions of this Section 4 shall not apply to any Transfer of shares of Common Stock: (i) to the public pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act, (ii) pursuant to a Liquidation Event, or (iii) to an Affiliate of Heat.

4.3

Termination of Co-Sale Rights. The provisions of this Section 4 shall expire and terminate as to each Stockholder upon the earlier of immediately prior to (a) the closing of the Initial Offering, (b) a Liquidation Event, or (c) the date the Company first becomes subject to the periodic reporting requirements of Sections 12(g) or 15(d) of the Exchange Act.

SECTION 5.

MISCELLANEOUS.

5.1

This Agreement and the relationship of the parties hereto shall be governed by and construed under the laws of the State of Delaware in all respects as such laws are applied to agreements among Delaware residents entered into and performed entirely within Delaware, without giving effect to conflicts of law principles thereof.

5.2

Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon the parties hereto and their respective successors, assigns, heirs, executors, and administrators and other legal representatives and shall inure to the benefit of and be enforceable by each Person who shall be a Stockholder from time to time.

5.4

Severability.

5.5

Amendment and Waiver. Except as otherwise expressly provided, this Agreement may be amended or modified, and the obligations of the Company and the rights of Heat and the Stockholders under this Agreement may be waived, only upon the written consent of the Company, Heat and the Stockholders holding a majority of the outstanding shares of Common Stock held by the Stockholders. Any such amendment, waiver or modification effected in accordance with this Section 5.5 shall be binding upon Heat, each Stockholder and the Company. By signing this Agreement, each Stockholder acknowledges and agrees that this Agreement may be

amended or modified, and the obligations of the Company and the rights of Heat and the Stockholder under this Agreement may be waived without such Stockholder’s written consent.

5.6

Delays or Omissions. It is agreed that no delay or omission to exercise any right, power, or remedy accruing to any party, upon any breach, default, or noncompliance by another party under this Agreement, shall impair any such right, power, or remedy, nor shall it be construed to be a waiver of any such breach, default, or noncompliance, or any acquiescence therein, or of or in any similar breach, default, or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent, or approval of any kind or character on any party’s part of any breach, default, or noncompliance under this Agreement or any waiver on such party’s part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement, by law, or otherwise afforded to any party, shall be cumulative and not alternative.

5.7

Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified; (b) when sent by confirmed electronic mail if sent during normal business hours of the recipient; if not, then on the next Business Day; (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one day after deposit with a nationally-recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to Heat, the Company and to each Stockholder at his, her, or its address as set forth on the signature pages hereto, or at such other address or electronic mail address as Heat, the Company or such Stockholder may designate by written notice to the other parties hereto.

5.8

Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

5.9

Pronouns. All pronouns contained herein, and any variations thereof, shall be deemed to refer to the masculine, feminine, or neutral, singular or plural, as the identity of the parties hereto may require.

5.10

Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

5.11

Termination. This Agreement shall terminate in its entirety upon the earlier to occur of immediately prior to (a) the closing of an Initial Offering; and (b) a Liquidation Event. Upon such termination, this Agreement shall forthwith become void and there shall be no liability on the part of any party to this Agreement, except for obligations under Section 2.1 (“Market Stand-Off” Agreement), which shall survive such termination. Notwithstanding the foregoing, nothing contained in this Agreement shall relieve any party from liability for any breach of this Agreement.

5.12

Exclusive Jurisdiction. Each of the parties hereto agrees that any suit, action, or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement shall be brought solely in the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, any state or federal court sitting in the State of Delaware. Each of the parties hereto consents to the jurisdiction of such court (and of the appropriate appellate courts therefrom) in any such suit, action, or proceeding and irrevocably agrees not to commence any litigation relating thereto except in such court, and each further waives any objection to the laying of venue of any such litigation in such court and agrees not to plead or claim in such court that such litigation brought therein has been brought in an inconvenient forum. Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 5.7. Nothing in this Section 5.12, however, shall affect the right of any Person to serve legal process in any other manner permitted by law.

5.13

Specific Performance. Each of the parties hereto agrees and acknowledges that Heat would be irreparably harmed in the event of a breach by any Stockholder of such Stockholder’s obligations hereunder, that monetary damages may not be an adequate remedy for such breach and that Heat shall be entitled to specific

performance or injunctive relief, without the need to post a bond or other security, in addition to any other remedy that Heat may have at law or in equity, in the event of such breach.

5.14

Waiver of Jury Trial. EACH OF THE PARTIES OF THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDINGS OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

FORM OF Demand PROMISSORY NOTE


$[•]	[__], 20__

FOR VALUE RECEIVED, including in connection with the transactions contemplated by that certain Stock Purchase Agreement, dated as of March 7, 2017, (the "Stock Purchase Agreement"), between Heat Biologics, Inc., a Delaware corporation ("Payee"), Pelican Therapeautics, Inc., a Delaware corporation ("Maker"), the stockholders of Maker and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, as the Stockholders’ Representative, MAKER hereby promises to pay to the order of PAYEE the principal amount of $[•], payable as provided herein, with interest from the date hereof accruing at the Contract Rate (as defined below) on all unpaid principal due hereunder. Interest shall be calculated on the basis of a year of three hundred sixty-five (365) days and charged for the actual number of days elapsed.

Payments.

Place. Payment of principal and interest shall be made by wire transfer, in immediately available funds in the lawful currency of the United States of America in, to the following bank account of Payee or such other place and method of payment designated in writing by Payee to Maker:

Account Name:

Payment on Demand and Maturity. Subject to the provisions of Section 2 hereof and paragraph C of this Section 1, the entire unpaid principal balance of this Demand Promissory Note (this "Promissory Note"), together with any unpaid and accrued interest and any additional amounts due and owing hereunder, shall be due and payable upon the earlier of (i) an Event of Default (as defined below) or (ii) demand by Payee; provided however, that Payee may not make such a demand until after Payee has made the first Milestone Payment (as defined in the Stock Purchase Agreement) pursuant to Section 1.4(a) of the Stock Purchase Agreement.

Interest Rate. From the date hereof through and including the date that the entire principal balance of this Promissory Note is paid in full, interest shall accrue on the outstanding principal balance hereunder at a rate per annum equal to 8.00% (the "Contract Rate").

Prepayments. Maker may make prepayments of the principal of, and the interest on, this Promissory Note in whole or in part at any time without premium or penalty. Prepayments shall be applied first to the payment of expenses due under this Promissory Note, second to interest accrued but unpaid on this Promissory Note and third, if the amount of prepayment exceeds the amount of all such expenses and accrued but unpaid interest, to the payment of principal on this Promissory Note.

Default Rate. Any principal payments not paid when due and, to the extent permitted by applicable law, any interest payment not paid when due, and any other amount due to Payee under this Promissory Note not paid when due, in any case whether at stated maturity, by notice of prepayment, by acceleration or otherwise, shall thereafter bear interest payable upon demand at a rate which is 2.00% in excess of the Contract Rate ("Default Rate").

Events of Default. The occurrence of any of the following described in paragraphs A through E below shall constitute an "Event of Default" under this Promissory Note:

Failure to Pay. Maker's failure to make any principal or interest payment under this Promissory Note when due.

Breach of Promissory Note. Maker's failure to observe or perform any covenant or other agreement with Payee contained in this Promissory Note.

Voluntary Bankruptcy or Insolvency Proceedings. Maker shall (i) apply for or consent to the appointment of a receiver, trustee, liquidator or custodian of itself or of all or substantially all of its property, (ii) make a general assignment for the benefit of its or any of its creditors, (iii) be dissolved or liquidated, or (iv) commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or consent to any such relief or to the appointment of or taking possession of its property by any official in an involuntary case or other proceeding commenced against it.

Involuntary Bankruptcy or Insolvency Proceedings. Proceedings for the appointment of a receiver, trustee, liquidator or custodian of Payee or of all or substantially all of Maker's property, or an involuntary case or other proceedings seeking liquidation, reorganization or other relief with respect to Maker or Maker's debts under any bankruptcy, insolvency or other similar law now or hereafter in effect shall be commenced and an order for relief entered or such proceeding shall not be dismissed or discharged within twenty (20) days of commencement.

Other Bankruptcy Events. Maker shall file an answer admitting the jurisdiction of the court and the material allegations of any involuntary petition against Maker under the U.S. Bankruptcy Code or any other applicable state or federal law relating to bankruptcy, reorganization, or other relief for debtors; Maker shall admit in writing that it is generally unable to pay its debts as they become due; or Maker shall be adjudicated a bankrupt, or an order for relief shall be entered against Maker as debtor by any court of competent jurisdiction under the U.S. Bankruptcy Code or any other applicable state or federal law relating to bankruptcy, reorganization or other relief for debtors.

Consequence of Event of Default. UPON THE OCCURRENCE OR EXISTENCE OF ANY EVENT OF DEFAULT DESCRIBED IN PARAGRAPHS A THROUGH E OF THIS SECTION 4, IMMEDIATELY AND WITHOUT NOTICE, ALL AMOUNTS THEN OUTSTANDING UNDER THIS PROMISSORY NOTE SHALL AUTOMATICALLY BECOME IMMEDIATELY DUE AND PAYABLE, WITHOUT PRESENTMENT, DEMAND, PROTEST OR ANY OTHER NOTICE OF ANY KIND, ALL OF WHICH ARE HEREBY EXPRESSLY WAIVED. IN ADDITION TO THE FOREGOING REMEDIES, UPON THE OCCURRENCE OR EXISTENCE OF ANY EVENT OF DEFAULT, PAYEE MAY EXERCISE ANY OTHER RIGHT POWER OR REMEDY PERMITTED TO IT BY LAW.

Other Remedies on Default. In case any one or more Events of Default shall occur, be continuing, and not have been waived, Payee may proceed to protect and enforce the rights of Payee by an action at law, suit in equity, or other appropriate proceeding, whether for the specific performance of any agreement contained herein or for an injunction against a violation of any of the terms hereof, or in aid of the exercise of any power granted hereby or thereby, or by law. The remedies provided in this Promissory Note shall be cumulative and in addition to all other remedies available under this Promissory Note at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit Payee's right to pursue actual and consequential damages for any failure by Maker to comply with the terms of this Promissory Note. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by Payee and shall not, except as expressly provided herein, be subject to any other obligation of Maker (or the performance thereof). Maker acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Payee and that the remedy at law for any such breach may be inadequate. Maker therefore agrees that, in the event of any such breach or threatened breach, Payee shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

Waivers. MAKER HEREBY WAIVES PRESENTMENT, DEMAND, NOTICE, PROTEST AND ALL OTHER DEMANDS AND ANY OTHER NOTICES (WHETHER OR NOT REQUIRED BY LAW) IN CONNECTION WITH SAID DELIVERY, ACCEPTANCE, PERFORMANCE, DEFAULT OR ENFORCEMENT OF THIS PROMISSORY NOTE. MAKER HEREBY WAIVES AND RENOUNCES ANY AND ALL EXEMPTION RIGHTS UNDER OR BY VIRTUE OF THE LAWS OF ANY

STATE, OR THE UNITED STATES, AS AGAINST THIS DEBT OR ANY RENEWAL DEBT. NO DELAY OR OMISSION ON THE PART OF PAYEE IN EXERCISING ANY RIGHT HEREUNDER SHALL OPERATE AS A WAIVER OF SUCH RIGHT OR OF ANY OTHER RIGHT. A WAIVER ON ANY ONE OCCASION SHALL NOT BE CONSTRUED AS A BAR TO OR WAIVER OF ANY SUCH RIGHT AND/OR REMEDY IN ANY FUTURE OCCASION.

Representations and Warranties of Maker. Maker represents and warrants, as of the date hereof, the following:

Neither the execution or delivery of this Promissory Note nor the observance and performance of the agreements and obligations contained herein or therein are prohibited by, in conflict with or constitute a breach of any contract, agreement or other instrument or any law, ordinance, regulation, order, writ or decree to which Maker is a party or by which Maker is bound;

This Promissory Note constitutes the legal, valid and binding obligation of Maker, enforceable against Maker in accordance with its terms;

There are no suits or proceedings by or before any court, commission, board or other governmental body pending, or to the knowledge of Maker threatened, which involve or affect the validity or enforceability of this Promissory Note or involve any risk of any judgment or liability being imposed upon Maker which could materially adversely affect the financial condition of Maker or Maker's ability to observe and perform its agreements and obligations hereunder;

Any and all federal, state and local income tax returns required to have been filed by Maker, as applicable, have been filed, or extensions for the filing thereof have been filed, and all taxes reflected upon any such tax returns, all past due taxes, interest and penalties and all estimated payments required to be paid to date have been paid; and

(i) Maker is not insolvent or bankrupt and has not committed any act of bankruptcy; (ii) Maker has not made any general assignment for the benefit of its creditors; (iii) no proceeding seeking (a) relief under any bankruptcy or insolvency law, (b) the rearrangement or readjustment of debt, or (c) the appointment of a receiver, custodian, liquidator or trustee to take possession of substantially all of the assets has been commenced or threatened with respect to Maker.

Covenants and Agreements of Maker. Until this Promissory Note has been paid in full as provided herein, Maker hereby covenants and agrees with Payee as follows:

No other indebtedness of Maker shall rank senior to the indebtedness evidenced by this Promissory Note. If Maker obtains indebtedness for borrowed money, such lender shall enter into a subordination agreement with Payee reasonably acceptable to Payee.

Maker will at all times take or cause to be taken all such action as may from time to time be necessary to maintain, preserve and renew its principal residence (as such term is used in the Uniform Commercial Code of the State of Delaware) as the State of [Texas].

Maker will perform, keep and observe all of the terms, conditions, covenants, agreements, warranties or representations contained in this Promissory Note.

Maker will pay promptly when due all taxes, assessments, governmental charges and levies owed by Maker and will comply with all laws applicable to Maker.

Maker will deliver to Payee its filed United States federal income tax returns for each tax year within thirty (30) days of the filing of Maker's federal income tax returns with the United States Internal Revenue Service for such tax year.

POWER TO CONFESS JUDGMENT. MAKER HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY OR CLERK OF ANY COURT OF RECORD, AFTER THE OCCURRENCE OF ANY EVENT OF DEFAULT HEREUNDER, TO APPEAR FOR MAKER, ITS SUCCESSORS, ASSIGNS, HEIRS, EXECUTORS, ADMINISTRATORS AND DULY APPOINTED LEGAL REPRESENTATIVES, AS APPLICABLE, AND, WITH OR WITHOUT COMPLAINT FILED, CONFESS JUDGMENT, OR A SERIES OF JUDGMENTS, AGAINST MAKER, ITS SUCCESSORS, ASSIGNS, HEIRS, EXECUTORS, ADMINISTRATORS AND DULY APPOINTED LEGAL REPRESENTATIVES, AS APPLICABLE, IN FAVOR OF PAYEE, ITS SUCCESSORS, ASSIGNS, HEIRS, EXECUTORS, ADMINISTRATORS AND DULY APPOINTED LEGAL REPRESENTATIVES, AS APPLICABLE, OR ANY HOLDER HEREOF FOR THE ENTIRE PRINCIPAL BALANCE OF THIS PROMISSORY NOTE AS IS THEN OUTSTANDING, ALL ACCRUED INTEREST AND ALL OTHER AMOUNTS DUE HEREUNDER, TOGETHER WITH COSTS OF SUIT AND AN ATTORNEYS' COMMISSION UP TO TWENTY PERCENT (20%) OF SUCH PRINCIPAL AND INTEREST ADDED AS A REASONABLE ATTORNEYS' FEE (PROVIDED, HOWEVER, THAT PAYEE SHALL ONLY SEEK TO RECOVER THOSE REASONABLE ATTORNEYS' FEES INCURRED BY IT FROM TIME TO TIME), AND FOR DOING SO, THIS PROMISSORY NOTE OR A COPY VERIFIED BY AFFIDAVIT SHALL BE A SUFFICIENT WARRANT. MAKER HEREBY FOREVER WAIVES AND RELEASES ALL ERRORS IN SAID PROCEEDINGS AND ALL RIGHTS OF APPEAL AND ALL RELIEF FROM ANY AND ALL APPRAISEMENT, STAY OR EXEMPTION LAWS OF ANY STATE NOW IN FORCE OR HEREAFTER ENACTED. INTEREST ON ANY SUCH JUDGMENT SHALL ACCRUE AT THE DEFAULT RATE.

NO SINGLE EXERCISE OF THE FOREGOING POWER TO CONFESS JUDGMENT, OR A SERIES OF JUDGMENTS, SHALL BE DEEMED TO EXHAUST THE POWER, WHETHER OR NOT ANY SUCH EXERCISE SHALL BE HELD BY ANY COURT TO BE INVALID, VOIDABLE, OR VOID, BUT THE POWER SHALL CONTINUE UNDIMINISHED AND IT MAY BE EXERCISED FROM TIME TO TIME AS OFTEN AS PAYEE SHALL ELECT UNTIL SUCH TIME AS PAYEE SHALL HAVE RECEIVED PAYMENT IN FULL OF THE PRINCIPAL, INTEREST, EXPENSES AND ANY OTHER DEBT OWED HEREUNDER. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, PAYEE MAY ENTER ONE OR MORE JUDGMENTS IN THE SAME OR DIFFERENT COUNTIES FOR ALL OR ANY PART OF THE OBLIGATIONS HEREUNDER, WITHOUT REGARD TO WHETHER JUDGMENT HAS BEEN ENTERED ON MORE THAN ONE OCCASION FOR THE SAME OBLIGATIONS. IN THE EVENT ANY JUDGMENT ENTERED AGAINST MAKER HEREUNDER IS STRICKEN OR OPENED UPON APPLICATION BY OR ON MAKER'S BEHALF FOR ANY REASON WHATSOEVER, PAYEE IS HEREBY AUTHORIZED AND EMPOWERED TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW TO AGAIN APPEAR FOR AND CONFESS JUDGMENT AGAINST MAKER ON THE BASIS PROVIDED FOR ABOVE. NOTWITHSTANDING THE ATTORNEYS' COMMISSION PROVIDED FOR IN THE PRECEDING PARAGRAPH (WHICH IS INCLUDED IN THE WARRANT FOR PURPOSES OF ESTABLISHING A SUM CERTAIN), THE AMOUNT OF ATTORNEYS' FEES THAT PAYEE MAY RECOVER FROM MAKER SHALL NOT EXCEED THE ACTUAL ATTORNEYS' FEES AND COSTS INCURRED BY PAYEE.

BEING FULLY AWARE OF ITS RIGHTS TO PRIOR NOTICE AND HEARING ON THE VALIDITY OF ANY CLAIMS THAT MAY BE ASSERTED AGAINST IT BY PAYEE UNDER THIS PROMISSORY NOTE BEFORE JUDGMENT CAN BE ENTERED AND BEFORE ASSETS OF MAKER CAN BE GARNISHED AND ATTACHED, MAKER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES THESE RIGHTS AND EXPRESSLY AGREES AND CONSENTS TO PAYEE, UPON THE OCCURRENCE OF AN EVENT OF DEFAULT, OR AT ANY TIME THEREAFTER, ENTERING JUDGMENT AGAINST MAKER BY CONFESSION AND ATTACHING AND GARNISHING THE BANK ACCOUNTS AND OTHER ASSETS OF MAKER, WITHOUT PRIOR NOTICE OR OPPORTUNITY FOR A HEARING.

THE POWERS OF ATTORNEY GRANTED HEREIN ARE COUPLED WITH AN INTEREST AND NOT REVOCABLE. SUCH POWERS ARE GIVEN PRIMARILY FOR BUSINESS OR COMMERCIAL PURPOSES. SUCH POWERS SHALL BE EXERCISED FOR THE BENEFIT OF PAYEE AND NOT FOR THE BENEFIT OF MAKER. IN ACTING UNDER SUCH POWERS, PAYEE HAS NO FIDUCIARY DUTY TO MAKER.

MAKER ACKNOWLEDGES THAT (A) IT HAS HAD THE ASSISTANCE OF ITS LEGAL COUNSEL IN THE REVIEW AND EXECUTION OF THIS PROMISSORY NOTE (OR HAS DECIDED NOT TO CONSULT COUNSEL), (B) IT HAS HAD THE OPPORTUNITY AND TIME TO REVIEW THIS PROMISSORY NOTE PRIOR TO ITS EXECUTION, AND (C) THE MEANING AND EFFECT OF THE FOREGOING PROVISIONS CONCERNING CONFESSION OF JUDGMENT HAVE BEEN FULLY EXPLAINED TO MAKER BY ITS COUNSEL (IF MAKER DECIDED TO CONSULT COUNSEL).

Miscellaneous.

Usury. In the event any interest is paid on this Promissory Note which is deemed to be in excess of the then legal maximum rate, then that portion of the interest payment representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied against the principal of this Promissory Note.

Invalidity. If any provision of this Promissory Note is invalid, illegal or unenforceable, the balance of this Promissory Note shall remain in effect, and if any provision is inapplicable to any person, entity or circumstance, it shall nevertheless remain applicable to all other persons, entities and circumstances. In such an event, the parties will in good faith attempt to effect the business agreement represented by such invalidated term to the fullest extent permitted by law. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision(s), then (i) such provisions(s) shall be excluded from this Promissory Note, (ii) the balance of the Promissory Note shall be interpreted as if such provision(s) were so excluded, and (iii) the balance of the Promissory Note shall be enforceable in accordance with its terms.

Set-off by Payee. Any sums at any time credited by or due from Payee to Maker under any other agreement or otherwise may at any time be applied to or set off against any amounts owed by Maker to Payee hereunder.
