For this purpose, “Total Consideration” shall mean the sum of: (i) the total cash payable to the Sellers pursuant to this Agreement (including, for the avoidance of doubt, that portion of the Milestone Payment to be paid in cash (if any) and cash to be paid in respect of fractional shares pursuant to Section 2.9 (if any)) in exchange for their Shares and (ii) the aggregate fair market value of shares of stock of the Buyer and the Series C Preferred Shares to be delivered to the Sellers pursuant to this Agreement in exchange for their Shares (including, for the avoidance of doubt, that portion of the Milestone Payment to be paid in stock of the Buyer and the Series C Preferred Shares and excluding, for the avoidance of doubt, cash to be paid in respect of fractional shares pursuant to Section 2.9 (if any)) (the “Value of Stock Consideration”). For this purpose, the (i) “fair market value” of shares of common stock of the Buyer shall mean the lowest of the following amounts, as reported on the NYSE: (A) the closing Buyer common stock trading price on the Valuation Date (as defined herein); (B) the average between the high and low Buyer common stock trading prices on the Valuation date; and (C) the volume weighted average of the trading prices of all shares of Buyer common stock traded on the Valuation Date and (ii) “fair market value” of Series C Preferred Shares shall be as determined by the Board of Directors of the Buyer acting in good faith. “Valuation Date” shall mean the applicable valuation date as Buyer determines is appropriate under Treasury regulation section 1.368-1(e)(2). The intent of the foregoing is to satisfy the continuity of interest requirement with the meaning of Code Section 368, the Treasury Regulations issued thereunder and judicial interpretations thereof. Notwithstanding anything to the contrary herein or otherwise in this Agreement, (x) in no event shall Buyer be liable to Sellers or any other Person for any Taxes or other liabilities or losses in the event that the purchase of the Shares and the Merger, taken together, or any other transaction contemplated by this Agreement, does not qualify as a reorganization under the provisions of Section 368(a) of the Code, and (y) in no event shall Buyer be required to take the position that the purchase of the Shares and the Merger, taken together, or any other transaction contemplated by this Agreement, qualifies as a reorganization under the provisions of Section 368(a) of the Code or any similar provision of state or local Law, or refrain from taking any position inconsistent with such position, for Tax purposes in any Tax Return or otherwise to the extent it reasonably determines, based on the advice of its tax advisor, that taking such position, or refraining from taking such position, as the case may be, is not permitted by Law.

(c) The right of any Seller to receive any amounts with respect to a Milestone Payment: (i) shall not be evidenced by a certificate or other instrument, (ii) shall not be assignable or otherwise transferable by such Seller, except by will, upon death or by operation of law, and (iii) does not represent any right other than the right to receive the Milestone Payment on the terms and conditions set forth herein if and to the extent payable. Any attempted transfer of the right to any amounts with respect to a Milestone Payment by any holder thereof (other than as specifically permitted by the immediately preceding sentence) shall be null and void.

Section 2.7 Post-Closing Adjustments.

(a) Within sixty (60) days after the Closing Date, the Company shall prepare and deliver to the Sellers’ Representative: (i) a final balance sheet of the Company, dated as of 11:59 p.m. on the Closing Date; (ii) the amount of Indebtedness as of immediately prior to the Closing; (iii) the amount of Cash as of immediately prior to the Closing; and (iv) a statement showing the calculation of the Preliminary Purchase Price, including the Transaction Expenses, whenever incurred, to the extent unpaid (such items, collectively, the “Final Closing Statement”). The Final Closing Statement shall be determined in accordance with GAAP.

(b) The Final Closing Statement shall become final and binding on the 30th day following delivery thereof to the Sellers’ Representative, unless prior to the end of such period, the Sellers’ Representative delivers to the Buyer written notice of its disagreement (a “Notice of Disagreement”) specifying the nature and amount of any dispute. The Sellers’ Representative shall be deemed to have agreed with all items and amounts not specifically referenced in the Notice of Disagreement, and such items and amounts shall not be subject to review in accordance with Section 2.7(c).

(c) During the thirty (30)-day period following delivery of a Notice of Disagreement by the Sellers’ Representative to the Buyer, the Parties in good faith shall seek to resolve in writing any differences that they may have with respect to the computation of the Final Closing Statement as specified in the Notice of Disagreement. Any disputed items resolved in writing between the Sellers’ Representative and the Buyer within such thirty (30)-day period shall be final and binding with respect to such items, and if the Sellers’ Representative and the Buyer agree in writing on the resolution of each disputed item specified by the Sellers’ Representative in the Notice of Disagreement, the amounts so determined shall be final and binding on the Parties for all purposes hereunder. If the Sellers’ Representative and the Buyer have not resolved all such differences by the end of such thirty (30)-day period, the Sellers’ Representative and the Buyer shall submit, in writing, to an independent public accounting firm (the “Independent Accounting Firm”), their briefs detailing their views as to the correct nature and amount of each item remaining in dispute, and the Independent Accounting Firm shall make a written determination as to each such disputed item, which determination must be in writing and must set forth, in reasonable detail, the basis therefor and shall be final and binding on the Parties for all purposes hereunder. The Independent Accounting Firm shall consider only those items and amounts in the Sellers’ Representative’s and the Buyer’s respective calculations that are identified as being items and amounts to which the Sellers’ Representative and the Buyer have been unable to agree. In resolving any disputed item, the Independent Accounting Firm may not assign a value to any item greater than the greatest value for such item claimed by either Party or less than the smallest value for such item claimed by either Party. The Independent

Accounting Firm shall be Abrams Little–Gill Loberfeld, PC, with a principal office at 1330 Boylston Street, Chestnut Hill, MA 02467, Attention Bernie A. Gold, CPA or, if such firm is unable or unwilling to act, another firm of certified public accountants of national reputation chosen by the Buyer and reasonably acceptable to the Sellers’ Representative (but which shall not be the Buyer’s corporate independent auditors). The Sellers’ Representative and the Buyer shall use their commercially reasonable efforts to cause the Independent Accounting Firm to render a written decision resolving the matters submitted to it as promptly as practicable, and in any event within thirty (30) days following the submission thereof. Judgment may be entered upon the written determination of the Independent Accounting Firm in any court having jurisdiction over the Party or Parties against which such determination is to be enforced. In acting under this Agreement, the Independent Accounting Firm will be entitled to the privileges and immunities of an arbitrator.

(d) The costs of any dispute resolution pursuant to Section 2.7(c), including the fees and expenses of the Independent Accounting Firm and of any enforcement of the determination thereof, shall be borne by the Sellers and the Buyer in inverse proportion as they may prevail on the matters resolved by the Independent Accounting Firm, which proportionate allocation shall be calculated on an aggregate basis based on the relative dollar values of the amounts in dispute and shall be determined by the Independent Accounting Firm at the time the determination of such firm is rendered on the merits of the matters submitted. The fees and disbursements of the Representatives of each Party incurred in connection with the preparation or review of the Final Closing Statement and preparation or review of any Notice of Disagreement, as applicable, shall be borne by such Party.

(e) The Buyer, during the period from and after the date of delivery of the Final Closing Statement through the resolution of any adjustment to the Preliminary Purchase Price contemplated by this Section 2.7, shall cause the Company to afford the Sellers’ Representative and its Representatives reasonable access, during normal business hours and upon reasonable prior notice, to the personnel, properties, books and records of the Company, and to any other information reasonably requested for purposes of preparing and reviewing the calculations contemplated by this Section 2.7. Each Party shall authorize its accountants to disclose work papers generated by such accountants in connection with preparing and reviewing the calculations of the Final Closing Statement as specified in this Section 2.7; provided that such accountants shall not be obligated to make any work papers available except in accordance with such accountants’ disclosure procedures and then only after the non-client Party has signed an agreement relating to access to such work papers in form and substance acceptable to such accountants.

(f) If, after final determination of the Final Closing Statement pursuant to Sections 2.7(a) to (c), the Preliminary Purchase Price is determined to be equal or greater than as set forth in the Preliminary Closing Statement (such excess, if applicable, the “Excess Amount”), then the Buyer shall, within ten Business Days after the Final Closing Statement becomes final and binding on the Parties hereto pursuant to this Section 2.7, (i) deliver or cause to be delivered to the Sellers, allocated to each in accordance with the percentages set forth in the Allocation Schedule, the Holdback Amount and (ii) if applicable, make payment of the Excess Amount by delivering or causing to be delivered to Sellers, allocated to each in accordance with the percentages set forth in the Allocation Schedule, shares of Buyer common stock, valued at the

Offering Price; provided that cash or stock shall be payable in respect of any fractional shares of Buyer stock in accordance with Section 2.9.

(g) If, after final determination of the Final Closing Statement pursuant to Sections 2.7(a) to (c), the Preliminary Purchase Price is determined to be less than as set forth in the Preliminary Closing Statement (such shortfall, the “Shortfall Amount”), then one of the following shall occur: (i) if the Shortfall Amount is greater than the Holdback Amount, then the Holdback Amount may be canceled by the Buyer and the Sellers shall, within ten Business Days after the Final Closing Statement becomes final and binding on the Parties hereto pursuant to this Section 2.7, deliver to the Buyer a number of Closing Initial Shares equal to the amount by which the Shortfall Amount exceeds the Holdback Amount by instructing the Buyer to cancel such number of Closing Initial Shares, allocated from each Seller in accordance with the percentages set forth in the Allocation Schedule or (ii) if the Shortfall Amount is less than the Holdback Amount then the Buyer shall, within ten Business Days after the Final Closing Statement becomes final and binding on the Parties hereto pursuant to this Section 2.7, (A) cancel a portion of the Holdback Amount equal to the Shortfall Amount and (B) distribute the remaining balance of the Holdback Amount to the Sellers, allocated to each in accordance with the percentages set forth in the Allocation Schedule; provided that cash or stock shall be payable in respect of any fractional shares of Buyer stock in accordance with Section 2.9.

Section 2.8 Withholding Rights. Each of the Buyer, the Company and their respective agents shall be entitled to deduct and withhold from any consideration otherwise payable to any Person pursuant to this Agreement such amounts as it determines it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of applicable Tax Law. To the extent that such amounts are so withheld and paid over to or deposited with the relevant Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the applicable Person in respect to which such deduction and withholding was made.

Section 2.9 Fractional Shares. No certificates or scrip or book-entry notations representing fractional shares of Buyer stock shall be issued to or delivered by Sellers pursuant to this Agreement. Notwithstanding any other provision of this Agreement, each Seller who would otherwise have been entitled to receive a fraction of a share of Buyer stock or who would otherwise have been obligated to deliver a fraction of a share of Buyer stock to the Buyer by instructing the Buyer to cancel shares of Buyer stock held by each Seller, shall receive or deliver, in respect thereof and upon surrender thereof, at the election of the Buyer, either (a) cash (without interest) in an amount determined by multiplying: (i) the Offering Price (or in the case of fractional Milestone Shares, the Milestone Price) by (ii) the fraction of a share of Buyer stock to which such Seller would otherwise be entitled to receive or obligated to deliver or (b) Buyer stock rounded up to the next whole share. As soon as practicable after the determination of the amount of cash or whole shares, if any, to be paid to Sellers or to Buyer in respect of any fractional share interests in shares of Buyer stock, the Buyer or Sellers, as applicable, shall make available such amounts, without interest, to the Buyer or Sellers, as applicable, entitled to receive such cash or whole shares.

(c) At such time as the Buyer is obligated to file a Registration Statement with the SEC pursuant to Section 6.8 hereof or otherwise include the Registrable Securities of the Sellers on a Registration Statement pursuant to this Section 6.8, the Buyer will use commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Buyer shall have the following obligations:

(i) At least three (3) calendar days prior to the filing of each Registration Statement, amendment, supplement or prospectus, the Buyer shall provide the Sellers’ Representative a copy of such Registration Statement, amendment, supplement or prospectus for the Sellers’ Representative’s review and comment. The Buyer shall not file any

Registration Statement, amendment, supplement or prospectus to which the Sellers’ Representative objects in good faith. If the Sellers’ Representative so objects to the filing of any Registration Statement, amendment, supplement or prospectus, the Buyer shall make any reasonable modifications to such Registration Statement, amendment, supplement or prospectus as may be required by such Sellers’ Representative (unless, upon the advice of counsel, such modifications would cause the Buyer to violate the Securities Act or any other applicable federal securities laws).

(ii) The Buyer shall submit to the SEC, within two (2) Business Days after the Buyer learns that no review of a particular Registration Statement will be made by the Staff or that the Staff has no further comments on a particular Registration Statement, as the case may be, a request for acceleration of effectiveness of such Registration Statement to a time and date not later than two (2) Business Days after the submission of such request.

(iii) The Buyer shall keep each Registration Statement effective pursuant to Rule 415 at all times until the earlier of: (A) the date on which the Sellers shall have sold all of the Registrable Securities covered by such Registration Statement; (B) the date as of which the Sellers may sell all of the Registerable Securities covered by such Registration Statement without restrictions or limitation pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1) (or any successor thereto) promulgated under the Securities Act; or (C) the first anniversary of the effective date of such Registration Statement (the “Registration Period”). The Buyer shall ensure that each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading.

(iv) The Buyer shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Buyer covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement.

(v) The Buyer shall furnish to each Seller without charge: (A) promptly after the Registration Statement including such Seller’s Registerable Securities is prepared and filed with the SEC, at least one copy of such Registration Statement and any amendment(s) thereto, including financial statements and schedules and all documents incorporated therein by reference, if requested by the Seller and (B) such other documents, including copies of any preliminary or final prospectus, as such Seller may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities.

(vi) The Buyer shall notify the Sellers’ Representative in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement, as then in effect, includes an

untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (provided that in no event shall such notice contain any material, nonpublic information), and, promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver a copy of such supplement or amendment to each Seller. The Buyer shall also promptly notify the Sellers’ Representative in writing (not later than two (2) Business Days following the date): (A) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective; (B) of any request by the SEC for amendments or supplements to a Registration Statement or related prospectus or related information; and (C) of the Buyer’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate.

(vii) The Buyer shall use commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify the Sellers who then hold Registrable Securities being sold of the issuance of such order and the resolution thereof or its receipt of notice of the initiation or threat of any proceeding for such purpose.

(viii) The Buyer shall hold in confidence and not make any disclosure of information concerning the Sellers provided to the Buyer unless: (A) disclosure of such information is necessary to comply with federal or state securities laws; (B) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement; (C) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction; or (D) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Buyer agrees that it shall, upon learning that disclosure of such information concerning the Sellers is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to the Sellers and allow the Sellers, at each Seller’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

(ix) The Buyer shall cooperate with the Sellers and, to the extent applicable, facilitate the timely preparation and delivery of book-entry shares (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement.

(x) If requested by a Seller, the Buyer shall: (A) as soon as reasonably practicable incorporate in a prospectus supplement or post-effective amendment such information as the Seller reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (B) as soon as reasonably practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such

prospectus supplement or post-effective amendment; and (C) as soon as reasonably practicable, supplement or make amendments to any Registration Statement if reasonably requested by a Seller.

(xi) The Buyer shall use commercially reasonable efforts to cause the Registrable Securities covered by a Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition of such Registrable Securities. In furtherance and not in limitation of the foregoing, the Buyer shall file such documents required of the Buyer for blue sky clearance in states specified in writing by the Sellers’ Representative and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Buyer is required to maintain the effectiveness of any Registration Statement pursuant to this Agreement; provided, however, that the Buyer shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented.

(xii) The Buyer shall otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder.

(xiii) Within five (5) Business Days after a Registration Statement that covers Registrable Securities is ordered effective by the SEC, the Buyer shall cause its counsel to issue an appropriate opinion or opinions to the transfer agent substantially to the effect that the Registrable Securities are subject to an effective registration statement and can be reissued free of restrictive legend upon notice of a sale by the holder thereof and confirmation by such holder that it has complied with the prospectus delivery requirements, provided that the Buyer has not advised the transfer agent orally or in writing that the opinion has been withdrawn.

(xiv) Notwithstanding anything to the contrary herein, at any time after the Registration Request, the Buyer may delay the disclosure of material, non-public information concerning the Buyer, the disclosure of which at the time would be, in the good faith opinion of the Board of Directors and its counsel, detrimental to the Buyer and, in the opinion of counsel to the Buyer, would not otherwise be required (a “Grace Period”); provided, that the Buyer shall promptly: (A) notify the Sellers’ Representative in writing of the existence of material, non-public information giving rise to a Grace Period (provided that in each notice the Buyer will not disclose the content of such material, non-public information to the Sellers’ Representative) and the date on which the Grace Period will begin and (B) notify the Sellers’ Representative in writing of the date on which the Grace Period ends; and, provided further, that the Grace Periods shall not exceed an aggregate of thirty (30) trading days during any 365-day period and the first day of any Grace Period must be at least thirty (30) days after the last day of any prior Grace Period (each, an “Allowable Grace Period”). For purposes of determining the length of a Grace Period above, the Grace Period shall begin on and include the date the Sellers’ Representative receives the notice referred to in clause (A) and shall end on and include the later of the date the Sellers’ Representative receives the notice referred to in clause (B) and the date referred to in such notice. The provisions of Section 6.8(c)(vi) hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of the Grace Period, the Buyer shall again be bound by the first sentence of Section 6.8(c)(vi) with respect to the information giving rise thereto unless such material, non-public information is no longer applicable. Notwithstanding

anything to the contrary, the Buyer shall cause its transfer agent to deliver unlegended shares of Buyer’s common stock to a transferee of any Seller in accordance with the terms of this Agreement in connection with any sale of Registrable Securities with respect to which a Seller has entered into a contract for sale, and delivered a copy of the prospectus included as part of the applicable Registration Statement (unless an exemption from such prospectus delivery requirement exists), prior to the Sellers’ Representative’s receipt of the notice of a Grace Period and for which the Seller has not yet settled.

(xv) Neither the Buyer nor any Affiliate thereof shall identify any Seller as an underwriter in any public disclosure or filing with the SEC or any applicable trading market and any Seller being deemed an underwriter by the SEC shall not relieve the Buyer of any obligations it has under this Agreement.

(xvi) The Buyer shall use commercially reasonable efforts to cause all of the Registrable Securities covered by a Registration Statement to be listed for trading or quotation, as applicable, on each trading market on which shares of Buyer’s common stock are then listed or quoted, if any, if the listing or quotation of such Registrable Securities is then permitted under the rules of such trading market. The Buyer shall pay all costs, fees and expenses in connection with satisfying its obligation under this Section 6.8(c)(xvi).

(d) At least five (5) calendar days prior to the first anticipated filing date of a Registration Statement, the Buyer shall notify each Seller in writing of the information the Buyer requires from such Seller in order to have that Seller’s Registrable Securities included in such Registration Statement. It shall be a condition precedent to the obligations of the Buyer to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Seller that the Seller shall furnish to the Buyer such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the effectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Buyer may reasonably request. Each Seller, by its acceptance of the Registrable Securities, agrees to cooperate with the Buyer as reasonably requested by the Buyer in connection with the preparation and filing of any Registration Statement hereunder, unless the Seller has notified the Buyer in writing of the Seller’s election to exclude all of the Seller’s Registrable Securities from such Registration Statement.

(e) Each Seller agrees that, upon receipt of any notice from the Buyer of the happening of any event of the kind described in Section 6.8(c)(vii) or the first sentence of Section 6.8(c)(vi), the Seller will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until the Seller’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 6.8(c)(vii) or the first sentence of Section 6.8(c)(vi) or receipt of notice that no supplement or amendment is required. Notwithstanding anything to the contrary, the Buyer shall cause its transfer agent to deliver unlegended shares of Buyer’s common stock to a transferee of the Seller in accordance with the terms of this Agreement in connection with any sale of Registrable Securities with respect to which the Seller has entered into a contract for sale prior to the Seller’s receipt of a notice from the Buyer of the happening of any event of the kind described in Section 6.8(c)(vii) or the first sentence of Section 6.8(c)(vi) and for which the Seller has not yet settled.

(f) Each Seller covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it or an exemption therefrom in connection with sales of Registrable Securities pursuant to the Registration Statement.

(g) All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Section 6.8, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Buyer, shall be paid by the Buyer.

(h) The rights under Section 6.8 shall be automatically assignable by a Seller to any transferee of all or any portion of the Seller’s Registrable Securities if: (A) the Buyer is, within a reasonable time after such transfer or assignment, furnished with written notice of (1) the name and address of such transferee or assignee and (2) the securities with respect to which such registration rights are being transferred or assigned; (B) at or before the time the Buyer receives the written notice contemplated by clause (A) of this sentence the transferee or assignee agrees in writing with the Buyer to be bound by all of the provisions contained herein; and (C) such transfer shall have been made in accordance with the applicable requirements of this Agreement.

(i) The Buyer will indemnify each Seller who holds Registrable Securities (if Registrable Securities held by such Seller are included in the securities as to which such registration is being effected), each of its officers and directors, partners, members and each person controlling such Seller within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on: (A) any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such Registration Statement, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading or (B) any violation by the Buyer of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Buyer in connection with any such registration, and in each case, the Buyer will reimburse each such Seller for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that the Buyer will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on: (1) any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Buyer by such Seller for use therein; (2) the use by a Seller of an outdated or defective prospectus after the Buyer has notified such Seller in writing that the prospectus is outdated or defective; or (3) a Seller’s (or any other indemnified person’s) failure to send or give a copy of the prospectus or supplement (as then amended or supplemented), if required, pursuant to Rule 172 under the Securities Act (or any successor rule) to the Persons asserting an untrue statement or alleged untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such person if such statement or omission was corrected in such prospectus or supplement;

provided, further, that the indemnity agreement contained in this Section 6.8(i) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Buyer (which consent shall not be unreasonably withheld, conditioned or delayed).

(j) Each Seller holding Registrable Securities will, if Registrable Securities held by such Seller are included in the securities as to which such registration is being effected, severally and not jointly, indemnify the Buyer, each of its officers and directors, other holders of the Buyer’s securities covered by such Registration Statement, each person who controls the Buyer within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on: (A) any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such Registration Statement, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Buyer by such Seller for use therein or (B) any violation by such Seller of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to such Seller in connection with any such registration, and in each case, such Seller will reimburse the Buyer, each other holder, and directors, officers, persons, underwriters or control persons of the Buyer and the other holders for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss, damage, liability or action; provided, that the indemnity agreement contained in this Section 6.8(j) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such indemnifying Seller (which consent shall not be unreasonably withheld, conditioned or delayed). The liability of any Seller for indemnification under this Section 6.8(j) in its capacity as a seller of Registrable Securities shall not exceed the amount of net proceeds to such Seller of the securities sold in any such registration.

(k) If the indemnification provided for in this Section 6.8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the untrue statement or omission that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct

or prevent such statement or omission; provided, that in no event shall any contribution by a Seller hereunder exceed the net proceeds to such Seller from the sale of the securities in such registration. The amount paid or payable by a party as a result of any loss, claim, damage or liability shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 6.8 was available to such party in accordance with its terms.
