UNIT PURCHASE AGREEMENT

     THIS UNIT PURCHASE AGREEMENT (this “Agreement”) is dated as of the second day of November, 2006, by and among (i) WebMD Health Corp., a Delaware corporation (the “Buyer”), (ii) Subimo, LLC, a Delaware limited liability company (the “Company”), (iii) ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇ ▇. ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇, and ▇▇▇▇ ▇▇▇▇▇▇▇▇ (each a “Principal Unitholder” and, collectively, the “Principal Unitholders”), being the holders of a majority of the limited liability company interests of the Company, and (iv) upon their respective execution of the Joinder at the Closing, each Person identified on Schedule 1.1 hereto (collectively, with the Principal Unitholders, the “Sellers”). Unless otherwise set forth herein, capitalized terms used herein shall have the meanings assigned to such terms in Section 9.

RECITALS

     WHEREAS, the Company is engaged in the business of providing employers, health plans, and consumers with online health related content, tools or applications that assist employees, plan members, and consumers in managing their health care costs, improving care, and/or making benefit, treatment, provider, or other health-related decisions (the “Business”).

     WHEREAS, immediately prior to the Closing, the Sellers will own all of the Units;

     WHEREAS, the Sellers desire to sell all of the Units to the Buyer, and the Buyer desires to purchase the Units from the Sellers, upon the terms and subject to the conditions contained in this Agreement; and

     WHEREAS, contemporaneously herewith, each of the Principal Unitholders have entered into employment agreements with the Company (each an “Employment Agreement” and, collectively, the “Employment Agreements”) that will become effective as of the Closing provided the respective party thereto is still employed by the Company.

     NOW, THEREFORE, in consideration of the mutual promises and agreements set forth herein, the Buyer, the Company and the Sellers agree as follows:

          1. SALE AND PURCHASE OF UNITS.

          1.1. Agreement to Sell. Subject to the terms and conditions set forth in this Agreement, each of the Sellers agrees to sell to the Buyer, and the Buyer agrees to purchase from each such Seller, at the Closing (as defined in Section 2.1), the Units owned by such Seller, or, in the case of the Options, to be owned by such Seller upon exercise thereof, as set forth opposite such Seller’s name on Schedule 1.1 hereto.

          1.2. Purchase Price.

               (a) In consideration for the Units, the Buyer shall pay to the Sellers in the manner set forth below, as the aggregate purchase price for all of the Units (the “Closing Purchase Price”) an amount equal to the sum of (i) US$34,000,000 (the “Cash Payment”) (as adjusted pursuant to Section 1.3), plus (ii) the Deferred Consideration, less (iii) the Transaction Expenses, subject to adjustment, at Closing and thereafter, as provided in Section 1.3, less (iv) Indebtedness, and plus or minus (v) the Purchase Price Adjustment, if any (as finally adjusted pursuant to Section 1.3, the “Purchase Price”).

               (b) [Intentionally Omitted].

               (c) On the Closing Date, the Buyer shall pay to the Sellers in cash, by wire transfer of immediately available funds to the account or accounts identified by the Seller Representative in writing at least two (2) Business Days prior to the Closing Date, an amount (the “Cash Purchase Price”) equal to (i) the Cash Payment (as adjusted pursuant to Section 1.3(a)), less (ii) the Cash Portion of the Transaction Expenses, and less (iii)

Indebtedness. At the Closing, the Cash Purchase Price shall be distributed among the Sellers pro rata in accordance with the percentages set forth on Schedule 1.1 (as updated on or prior to the Closing to reflect the exercise of Options) (with respect to each Seller, his, her or its “Pro Rata Share”), by wire transfer of immediately available funds; provided, that the amount of cash paid by Buyer and distributed to individual Sellers pursuant to this Section 1.2(c) shall be appropriately reduced to reflect (x) deductions authorized by Sellers pursuant to Section 2.2(a)(ii) and (y) any payments to Option holders that are to be made pursuant to arrangements implemented under Section 1.5.

               (d) Except as otherwise provided herein:

                    (i) On the date that is the earlier to occur of (1) a Change of Control, and (2) the Deferred Consideration Payment Date (the “Triggering Date”), the Buyer shall promptly issue, without limitation or contingencies, to the Sellers’ Broker the Sellers’ Broker’s Shares and (after giving effect to the issuance of the Sellers’ Broker’s Shares) shall issue to each Seller its Pro Rata Share of the Deferred Consideration.

                    (ii) If (1) on the Triggering Date, or (2) if prior to the Triggering Date, in the event the Buyer delivers the Registration Notice pursuant to Section 11.1, on the earlier to occur of (y) the date the Seller Registration Statement is declared effective by the SEC or (z) the date the Buyer notifies the Seller Representative that the Seller Registration Statement will not be declared effective by the SEC, but in no event later than sixty (60) days after the filing of the Seller Registration Statement ((1) or (2) above, whichever is applicable, is referred to herein as the “Applicable Date”), the aggregate value of the cash portion of the Subsequent Consideration, if any, paid plus the number of Shares issued, or to be issued, pursuant to this Section 1.2(d) (including the Sellers’ Broker’s Shares) is less than (I) $15,600,000 less (II) the amount of any Damages that are set off from time to time pursuant to Buyer’s right of setoff under Section 13.7 below) (the “Protection Value”), based upon the average closing price on NASDAQ (or any exchange on which the Common Stock is then listed, or if the Common Stock is not so listed, then as reasonably determined by the Board of Directors of Buyer) for the Common Stock for the five (5) Business Days prior to the Applicable Date (the value of such cash portion of the Subsequent Consideration, if any, plus Shares being referred to as the “Deferred Consideration Payment Date Value”), then, in addition to the Subsequent Consideration (including the Sellers’ Broker Shares) the Buyer shall issue or pay, as applicable, to the Sellers’ Broker and to the Sellers, in the aggregate, the amount by which the Deferred Consideration Payment Date Value is less than the Protection Value (the “Downside Protection Obligation”) in the form of additional Shares and/or in cash, as determined by Buyer in its sole discretion. The issuance of additional Shares or the payment of additional cash in satisfaction of the Downside Protection Obligation shall be made on a pro rata basis based on the number of Shares that would have otherwise been issuable to the Sellers’ Broker and each Seller as calculated immediately prior to the adjustments contemplated by this Section 1.2(d)(ii).

                    (iii) Notwithstanding any other provision of this Agreement, in the event of the Termination of Continued Employment of a Founder on or prior to the Deferred Consideration Payment Date, the Buyer shall have no obligation to issue to such Founder his or her Pro Rata Share of the Deferred Consideration (including the Downside Protection Obligation, if any) until the date that is the earlier to occur of (i) a Change of Control, and (ii) the Secondary Deferred Consideration Payment Date (the “Secondary Triggering Date”). For the avoidance of doubt, in the event of the Termination of Continued Employment of a Founder on or prior to the Deferred Consideration Payment Date, the Downside Protection Obligation with respect to such Founder shall be calculated as of the Applicable Date even if such Founder’s Pro Rata Share of the Deferred Consideration (including the Downside Protection Obligation, if any) is not issued until the Secondary Triggering Date.

          1.3. Adjustments to Purchase Price.

               (a) At the Closing, the Seller Representative shall deliver to the Buyer a good faith estimate of the Indebtedness and the Closing Net Working Capital (the “Estimated Net Working Capital”). If the Estimated Net Working Capital is less than $650,000 (the “Closing Net Working Capital Target”), the Cash Purchase Price initially payable at the Closing shall be reduced by the amount by which the Closing Net Working Capital Target exceeds the Estimated Net Working Capital (the “Initial Net Working Capital Deficiency”). The adjustment made

to the Cash Purchase Price initially payable at the Closing pursuant to this paragraph (a) is referred to herein as the “Initial Adjustment,” and shall be subject to subsequent adjustment as provided in paragraphs (b), (c) and (d) below.

               (b) Within sixty (60) days after the Closing Date, the Buyer shall prepare and deliver to the Seller Representative a balance sheet of the Company as of the Closing Date, immediately prior to giving effect to the Closing, prepared in accordance with GAAP applied on a basis consistent with the Most Recent Audited Balance Sheet, except for normal recurring year-end adjustments and the absence of footnotes (the “Final Closing Statement”). Calculations of Closing Net Working Capital shall be made based upon the Final Closing Statement in accordance with and on substantially the same basis as the Pro Forma Closing Net Working Capital attached hereto as Exhibit B. The Buyer shall permit the Seller Representative and its accountants to consult with the Buyer’s accountants in connection with the preparation of the Final Closing Statement and shall permit the Seller Representative’s accountants at the earliest practicable date to review and make copies of all work papers, schedules and calculations used in the preparation thereof (subject to the execution of any confidentiality and indemnification agreements required to be executed by the Buyer’s accountants).

               (c) When the Buyer delivers the Final Closing Statement, the Buyer shall also deliver a certificate (i) certifying that the Final Closing Statement was prepared in accordance with GAAP and in accordance with the procedures set forth in paragraph (b) above, and (ii) containing the Buyer’s calculations, based on the Final Closing Statement (the “Buyer’s Proposed Calculations”), of the Closing Net Working Capital, Indebtedness and Transaction Expenses. Within thirty (30) days after receipt of the Final Closing Statement and the accompanying certificate, the Seller Representative shall notify the Buyer of its agreement or disagreement with the Final Closing Statement and the accuracy of any of the Buyer’s Proposed Calculations, provided that if the Seller Representative disagrees with any of the foregoing, it shall provide a reasonably detailed explanation of such disagreement. If the Seller Representative disputes any aspect of the Final Closing Statement or the amount of any of the Buyer’s Proposed Calculations, then the Seller Representative shall have the right to direct its independent accountants, at the Sellers’ expense, to review and test the Final Closing Statement. The Seller Representative’s accountants shall complete their review and test within thirty (30) days after the date the Seller Representative disputes the Buyer’s Proposed Calculations. If the Seller Representative and its independent accountants, after such review and test, still disagree with the Buyer’s Proposed Calculations, and the Buyer does not accept the Seller Representative’s proposed alternative calculations (the “Seller Representative’s Proposed Calculations”), then the Buyer and the Seller Representative shall promptly select another nationally recognized independent accounting firm (other than the Company’s and the Buyer’s current independent accountants) (such accounting firm being the “Independent Accounting Firm”) to resolve the remaining disputed items (the “Remaining Disputed Items”) within thirty (30) days after the date of the Seller Representative’s rejection of the Buyer’s Proposed Calculations by conducting its own review and test of the Final Closing Statement and thereafter selecting either the Sellers’ Proposed Calculations of the Remaining Disputed Items or the Buyer’s Proposed Calculations of the Remaining Disputed Items or an amount in between the two. Each of the Sellers and the Buyer agrees that it shall be bound by the Independent Accounting Firm’s determination of the Remaining Disputed Items. The fees and expenses of the Independent Accounting Firm shall be paid 50% by the Sellers and 50% by the Buyer, provided, however, that if the difference between the Closing Net Working Capital and the Closing Net Working Capital that would have resulted from the use of the Proposed Calculations of one of the parties hereto (the “Erroneous Party”) is more than twice as great as the difference between the Closing Net Working Capital and the Closing Net Working Capital that would have resulted from the use of the other party’s Proposed Calculations, the Erroneous Party shall pay all of the fees and expenses of the Independent Accounting Firm.

               (d) Upon the determination pursuant to paragraph (c) of this Section 1.3 of the Final Closing Statement and the Closing Net Working Capital, the Closing Purchase Price shall be recalculated pursuant to the formula contained in Section 1.2(a) using the Closing Net Working Capital, Indebtedness, and Transaction Expenses determined pursuant to Section 1.3(c) in lieu of the Estimated Net Working Capital, Indebtedness, and Transaction Expenses amounts used in the Initial Adjustment for purposes of the Closing.

               (e) If the Closing Net Working Capital Target exceeds the Closing Net Working Capital (a “Closing Net Working Capital Deficiency”), then the amount of such excess shall reduce the Purchase Price pursuant to the formula contained in Section 1.2(a), and, on the date that is five (5) Business Days after determination of the Closing Net Working Capital, the Sellers shall jointly and severally pay to Buyer an amount equal to such Closing Net Working Capital Deficiency (minus the amount of Initial Net Working Capital Deficiency

withheld by Buyer pursuant to Section 1.3(a), if any but subject to the last sentence of this Subsection (e)) by wire transfer or delivery of other available funds. Buyer shall have the option of recouping all or any part of any such amount Sellers owe Buyer pursuant to this Section 1.3(e) by notifying the Seller Representative that Buyer is exercising its right of setoff pursuant to Section 13.7. Notwithstanding the foregoing, if the amount of the Initial Net Working Capital Deficiency exceeds the Closing Net Working Capital Deficiency, then the Buyer shall pay to the Sellers an aggregate amount equal to such excess by wire transfer or delivery of other available funds.

               (f) If the Closing Net Working Capital exceeds the Closing Net Working Capital Target (a “Closing Net Working Capital Surplus”), then the amount of such excess shall increase the Purchase Price pursuant to the formula contained in Section 1.2(a), and, on the date that is five (5) Business Days after determination of the Closing Net Working Capital, the Buyer shall pay to the Sellers an aggregate amount equal to such Closing Net Working Capital Surplus plus the amount of Initial Net Working Capital Deficiency withheld by Buyer pursuant to Section 1.3(a), if any, by wire transfer or delivery of other available funds.

          1.4. Delivery of Certificates by Sellers. If the Units have been certificated, each Seller hereby agrees to deliver to the Company, or counsel to the Company, such certificates representing his, her or its portion of the Units (along with duly executed stock powers) at least two (2) Business Days prior to the Closing.

          1.5. Withholding Taxes. Notwithstanding any other provision of this Agreement, Buyer shall, on behalf of the Company, withhold Taxes in connection with the exercise of the Options by holders of Options who are listed on Schedule 1.5 and elect to exercise their Options in the manner described in Section 2.2(a)(ii). The amount of the Taxes to be withheld and the amount of the reduction to the Cash Purchase Price paid to each such Seller shall be determined by applying the federal, state, and local income and employment withholding tax rates applicable to such Seller to an amount equal to (i) such Seller’s Pro Rata Share of the Cash Purchase Price, as reduced by the Initial Adjustment pursuant to Section 1.3(a); plus (ii) such Seller’s Pro Rata Share of the Subsequent Consideration Closing Date Value; less (iii) the aggregate exercise price of such Seller’s Options. The Buyer shall pay the amounts so withheld to the appropriate taxing authority within the time required by law and shall report such payments using the Company’s federal, state, and/or local employer identification number or numbers that were effective immediately prior to Closing. At the Buyer’s request, the Company shall cooperate in making arrangements to effect such tax withholdings, including by arranging for payments to Option Holders to be made through the Company’s existing payroll service provider. The Buyer shall have the right to collect any necessary Tax forms or similar information from any Seller or other recipient of a payment hereunder (including, without limitation, IRS Forms W-9 and W-8), and to withhold any applicable Taxes to the extent that a Seller or other recipient of a payment fails to provide such Tax forms or information as may be required to establish an exemption from withholding. Except as provided in this Section 1.5 and in Section 6.5, the Buyer will not deduct and withhold Taxes from any other payment of the Purchase Price to any Seller unless Buyer determines in good faith that such deduction or withholding is required by Law and notifies the Seller Representative of such determination in advance of making of the relevant payment. In the event that the Seller Representative disputes Buyer’s determination, the parties shall jointly retain a nationally recognized independent accounting firm (other than the Company’s and the Buyer’s current independent accountants) to resolve the dispute and such resolution will be binding on the parties. To the extent that amounts are withheld and paid to the appropriate taxing authority, such withheld amounts shall be treated for all purposes of this Agreement as having been delivered and paid to the applicable Seller in respect of which such withholding was made.

          1.6. Tax Reporting for Option Exercise.

               (a) With respect to holders of Options who are listed on Schedule 1.5 and elect to exercise their Options in the manner described in Section 2.2(a)(ii), the Buyer shall cause the Company to include on information returns filed with the appropriate taxing authorities as compensation income from the exercise of each such Seller’s Options an amount equal to (i) such Seller’s Pro Rata Share of the Cash Purchase Price, as reduced by the Initial Adjustment pursuant to Section 1.3(a); plus (ii) such Seller’s Pro Rata Share of the Subsequent Consideration Closing Date Value; less (iii) the aggregate exercise price of such Seller’s Options. The Buyer shall also cause the Company to report on such information returns any amounts withheld with respect to each such Seller. Such amounts shall be reported using the Company’s federal, state, and/or local employer identification number or numbers that were effective immediately prior to Closing. Buyer shall deliver copies of such returns to

the tax matters partner of the Company for its taxable year ending on the Closing Date promptly after Buyer files such information returns.

               (b) In addition to any other tax items properly allocable to such individuals under applicable Law, the Company will report on its Partnership Returns (including on appropriate Schedules K-1) for the taxable year ending on the Closing Date to each of the Sellers listed on Schedule 1.6(b) a guaranteed payment arising from the exercise of such Seller’s Options in an amount equal to (i) such Seller’s Pro Rata Share of the Cash Purchase Price, as reduced by the Initial Adjustment pursuant to Section 1.3(a), determined solely with respect to the Units acquired upon the exercise of such Seller’s Options; plus (ii) such Seller’s Pro Rata Share of the Subsequent Consideration Closing Date Value determined solely with respect to the Units acquired upon the exercise of such Seller’s Options; less (iii) the aggregate exercise price of such Seller’s Options.

          2. CLOSING.

          2.1. Time and Place. The closing of the sale and purchase of the Units (the “Closing”) shall be held at the offices of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, at 10:00 a.m. on the third Business Day following the satisfaction or waiver of all other conditions set forth in Sections 7 and 8 (other than delivery of customary closing documents), or at such other time, or at such other place as the Buyer and the Seller Representative may mutually agree.

This representation shall not apply to withholding obligations resulting from the exercise of Options by the Persons listed on Schedule 1.5 for whom the Buyer has agreed to effect withholding pursuant to Section 1.5. All individuals who have performed services for the Company while classified as independent contractors have, in all material respects, satisfied the requirements of Law to be so classified, and the Company has fully and accurately reported their compensation on IRS Forms 1099 or other applicable forms for independent contractors when required to do so.

The parties shall treat such transactions as occurring as of close of business on the Closing Date.

                    (ii) The parties agree that the Purchase Price, the liabilities of the Company and any other relevant items shall be allocated among the Assets in accordance with Section 1060 of the Code and the Treasury regulations thereunder.

A Seller may not transfer any of his, her or its Shares following the termination of the restrictions pursuant to Section 10.11 unless each such transferee agrees in a written instrument delivered to the Buyer to be bound by the provisions of this Section 11, in which case such transferee shall be deemed a Seller for purposes of this Section 11, unless the restrictions of this Section 11.5 are no longer effective as described in Section 11.3.

          11.6. Indemnification.

               (a) To the extent permitted by law, the Buyer will indemnify each Seller and each person controlling such Seller within the meaning of Section 15 of the Securities Act, with respect to which a Seller Registration Statement has been filed pursuant to this Section 11, and each underwriter for such Seller, if any, and each person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all

expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, preliminary or final, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration, 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 not misleading, or any violation by the Buyer of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation thereunder applicable to the Buyer and relating to action or inaction required of the Buyer in connection with any such registration, and will reimburse each such Seller and each person controlling such Seller, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling 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 any untrue statement (or alleged untrue statement) or omission (or alleged omission therefrom) 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 or on behalf of such Seller or its agents, underwriter or persons who control such Seller specifically for use in such prospectus, preliminary or final offering circular or other document (including any related registration statement, notification or the like). It is agreed that the indemnity agreement contained in this Section 11.6(a) 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).

               (b) Each Seller will, if Shares held by him, her, or it are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Buyer and each Person controlling the Buyer within the meaning of Section 15 of the Securities Act and each underwriter, if any, of the Buyer’s securities covered by a Seller Registration Statement, each person who controls such underwriter within the meaning of Section 15 of the Securities Act, each other such Seller and each of their officers, directors and partners, and each person controlling such Seller, against all expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, preliminary or final, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Buyer and such Sellers or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only 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 or on behalf of such Seller, its agents, underwriter or persons who control such Seller specifically for use in connection with such registration; provided, however, that the obligations of such Seller hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such Seller (which consent shall not be unreasonably withheld, conditioned or delayed) and provided further that in no event shall any indemnity under this Section 11.6(b) exceed the net proceeds from the offering received by such Seller.

               (c) If the indemnification provided for in this Section 11.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense 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 statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined 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 from the offering received by such Seller.

               (d) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

               (e) The obligations of the Buyer and the Sellers under this Section 11.6 shall survive completion of any offering of Shares and the termination of this Agreement.

          11.7. Registration Procedure. In the case of any Seller Registration Statement filed by the Buyer pursuant to this Section 11, the Buyer will keep the Seller Representative advised in writing as to the initiation of each registration and as to the progress and completion thereof. At its expense, the Buyer will use reasonable best efforts to:

               (a) Keep the Seller Registration Statement effective for a period of one hundred twenty (120) days or until the Sellers have completed the distribution described in the registration statement relating thereto, whichever first occurs; provided, however that (i) such 120-day period shall be extended for a period of time equal to the period the Seller refrains from selling any Shares at the request of an underwriter of the offering; and (ii) in the case of any registration of Shares that are intended to be offered on a continuous or delayed basis, such 120-day period shall be extended, if necessary, to keep the registration statement effective until all such Shares are sold;

               (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

               (c) Furnish such number of prospectuses and other documents incident thereto, including a preliminary prospectus and any amendment of or supplement to the prospectus, as a Seller from time to time may reasonably request;

               (d) Notify each Seller, at any time when a prospectus relating to the Shares is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in the Seller Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in the light of the circumstances then existing, and at the request of any such Seller, prepare and furnish to such Seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Shares, such prospectus shall not include an 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 not misleading or incomplete in the light of the circumstances then existing;

               (e) Cause all Shares to be listed on each securities exchange on which similar securities issued by the Buyer are then listed; and

               (f) Otherwise use reasonable best efforts to comply with all applicable rules and regulations of the SEC.

          11.8. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC which may permit the sale of the Shares to the public without registration, in the event the Buyer does not file a Seller Registration Statement, the Buyer agrees (to the extent Rule 144(k) under the Securities Act is not then available) to use reasonable best efforts to:

               (a) make and keep current public information available as those terms are understood and defined in Rule 144 under the Securities Act at all times following the Deferred Consideration Payment Date and so long as any Seller owns any Shares;

               (b) so long as a Seller owns any Shares, furnish to the Seller forthwith upon written request a written statement by the Buyer as to its compliance with the reporting requirements of Rule 144.

          12. EXCLUSIVE DEALING.

          12.1. The Company and the Sellers hereby agree that during the Exclusivity Period (as defined below), they shall not, and the Company shall require each of its officers, managers, employees, representatives and agents not to, directly or indirectly, (i) initiate, solicit, encourage or otherwise facilitate any inquiry, proposal, offer or discussion with any party (other than the Buyer) concerning any merger, reorganization, consolidation, recapitalization, business combination, liquidation, dissolution, share exchange, sale of units, sale of material assets or similar business transaction involving the Company or any division of the Company, (ii) furnish any non-public information concerning the business, properties or assets of the Company or any division of the Company to any party (other than the Buyer) or (iii) engage in discussions or negotiations with any party (other than the Buyer) concerning any such transaction. The Exclusivity Period shall be the period commencing on the date hereof and ending on the earlier of the Closing Date or the date on which this Agreement is terminated in accordance with the provisions hereof.

          12.2. The Company shall immediately notify any party with which discussions or negotiations of the nature described in paragraph (a) above were pending that the Company is terminating such discussions or negotiations. If the Company receives any inquiry, proposal or offer of the nature described in paragraph (a) above, the Company shall, within one Business Day after such receipt, notify the Buyer of such inquiry, proposal or offer, including the identity of the other party and the terms of such inquiry, proposal or offer.

          13. INDEMNIFICATION.

          13.1. Indemnity by the Sellers. Subject to the overall limitations, the minimum amounts and the time limitations set forth in Section 13.4, each of the Sellers agrees jointly and severally with respect to Sections 13.1(a), (c), (e), and (f) and severally, and not jointly, with respect to Sections 13.1(b) and (d), to indemnify and hold the Buyer harmless from and with respect to any and all claims, liabilities, losses, damages, costs and expenses, including without limitation the reasonable fees and expenses of counsel (collectively, “Damages”), related to or arising directly or indirectly out of:

               (a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of the Company contained in this Agreement or any other agreement or instrument furnished by the Company to the Buyer pursuant to this Agreement or any breach of the covenant of the Company contained in Section 10.4;

               (b) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of a Seller contained in this Agreement or any other agreement or instrument furnished by such Seller to the Buyer pursuant to this Agreement;

               (c) any failure to perform any covenant or agreement of the Company or such Seller contained in this Agreement or any agreement or instrument furnished by the Company or such Seller other than Section 10.4;

               (d) any failure of any Seller to have good, valid and marketable title to the issued and outstanding Units issued in the name of such Seller, free and clear of all Liens or any claim by a purported member of the Company against a Seller for failure to convey to such purported member valid and marketable title to the Units;

               (e) any Closing Net Working Capital Deficiency; or

               (f) except for a claim made against a Seller by a purported member of the Company for failure of a Seller to convey to such purported member valid and marketable title to the Units, any claim brought against the Company by a member or former member of the Company, or any other person or entity, seeking to assert, or based upon:

                    (i) ownership or rights to ownership of any Membership Interest in the Company;

                    (ii) any rights of a member (other than the right to receive the Purchase Price pursuant to this Agreement), including any option, preemptive rights or rights to notice or to vote;

                    (iii) any rights under the Limited Liability Company Agreement or Certificate of Formation of the Company; or

                    (iv) any claim that his, her or its Membership Interests were wrongfully repurchased by the Company.

          13.2. Indemnity by the Buyer. The Buyer agrees to indemnify and hold each of the Sellers harmless from and with respect to any and all Damages, related to or arising directly or indirectly out of any breach by the Buyer of any representation or warranty or covenant made by the Buyer in this Agreement.

          13.3. Indemnification Claims.

               (a) The Buyer shall give written notification to the Seller Representative of the commencement of any Third Party Action. Such notification shall be given within 20 days after receipt by the Buyer of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by the Buyer) the facts constituting the basis for such Third Party Action and the amount of the claimed damages; provided, however, that no delay or failure on the part of the Buyer in so notifying the Seller Representative shall relieve the Sellers of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure. Within 20 days after delivery of such notification, the Seller Representative may, upon written notice thereof to the Buyer, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Buyer; provided that (i) the Seller Representative may only assume control of such defense if (A) it acknowledges in writing to the Buyer that any damages, fines, costs or other liabilities that are assessed against the Buyer in connection with such Third Party Action constitute Damages for which the Buyer shall be indemnified pursuant to this Section 13 and (B) the ad damnum is less than or equal to the amount of Damages for which the Sellers are liable under this Section 13 and (ii) the Seller Representative may not assume control of the defense of a Third Party Action involving criminal liability or in which equitable relief is sought against the Buyer. If the Seller Representative does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Buyer shall control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and expenses of counsel to the Buyer with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Buyer controls the defense of such Third Party Action pursuant to the terms of this Section 13.3 or (ii) the Seller Representative assumes control of such defense and the Buyer reasonably concludes that the Sellers and the Buyer have conflicting interests or different defenses available with respect to such Third Party Action. The Seller Representative shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Buyer, which shall not be unreasonably withheld, conditioned or delayed. The Buyer shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Seller Representative, which shall not be unreasonably withheld, conditioned or delayed.

               (b) In order to seek indemnification under this Section 13, an Indemnified Party shall deliver to the Indemnifying Party a written notification which contains (i) a description of and amount of any Damages incurred or reasonably expected to be incurred by the Indemnified Party (the “Claimed Amount”) of such Damages, to the extent then known, (ii) a statement that the Indemnified Party is entitled to indemnification under Section 10.3(c) or Section 13 for such Damages and a reasonable explanation of the basis therefor, and (iii) a demand for payment in the amount of such Damages (a “Claim Notice”).

               (c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a written response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer and is seeking or required to enforce such claim pursuant to Section 13.7, the Buyer shall reduce the Subsequent Consideration to be paid or issued hereunder pursuant to Section 13.7), (ii) agree that the Indemnified Party is entitled to receive part, but not all, of the Claimed Amount (the “Agreed Amount”) (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer and is seeking or required to enforce such claim pursuant to Section 13.7, the Buyer shall reduce the Subsequent Consideration to be issued or paid hereunder pursuant to Section 13.7) or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount (a “Response”).

               (d) During the 30-day period following the delivery of a Response in which the Indemnifying Party disputes its liability for all or part of the Claimed Amount (a “Dispute”), the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute.

               (e) For purposes of this Section 13.3 if the Sellers comprise the Indemnifying Party, any references to the Indemnifying Party (except provisions relating to an obligation to make any payments) shall be deemed to refer to the Seller Representative, and (ii) if the Sellers comprise the Indemnified Party, any references to the Indemnified Party (except provisions relating to an obligation to make or a right to receive any payments) shall be deemed to refer to the Seller Representative. The Seller Representative shall have full power and authority on behalf of each Seller to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, the Sellers under this Section 13. The Seller Representative shall have no liability in to any Seller for any action taken or omitted on behalf of the Sellers pursuant to this Section 13.

          13.4. Limitations of Liability.

               (a) Subject to paragraphs (c)-(f) below, the Sellers shall not be required to indemnify the Buyer hereunder with respect to claims for Damages under Section 13.1(a) and/or (b) except to the extent that the aggregate amount of Damages with respect to any claim or series of related claims for which the Buyer is otherwise entitled to indemnification pursuant to Section 13.1(a) and/or (b) exceeds the Minimum Claim Amount (it being understood and agreed that the Sellers shall not be liable for any Damages with respect to any claim or series of related claims in the event that such Damages are less than the Minimum Claim Amount) and the aggregate amount of Damages for which the Buyer is otherwise entitled to indemnification pursuant to Section 13.1(a) and/or (b) exceeds the Deductible Amount (it being understood and agreed that (i) any such claim or series of related claims for Damages of less than the Minimum Claim Amount shall be disregarded for purposes of calculating the Deductible Amount and (ii) the Deductible Amount is intended as a deductible, and the Sellers shall not be liable for any Damages less than the Deductible Amount for which the Buyer is otherwise entitled to indemnification); provided, however, that the Minimum Claim Amount and the Deductible Amount shall not apply to any fraudulent misrepresentation or the misrepresentation, breach or inaccuracy of any representation or warranty made by the Company or any Seller, as applicable, in any of the following Sections: 3.1 (organization; authority; binding effect), 3.3 (capitalization), 3.7 (Taxes), 3.17 (Indebtedness), 4.1 (right to sell Units), 4.2 (title to Units), 4.4 (litigation); 4.5 (brokers) and 4.6 (investment intent) (collectively, the “Excluded Warranty Claims”).

               (b) (A) the aggregate Damages payable by the Sellers under this Agreement with respect to all claims for indemnification under Section 13.1(a) and/or (b) shall not exceed an amount equal to the Maximum Amount, and (B) the aggregate Damages payable by each Seller pursuant to Section 13.1(a) and/or (b) with respect to all claims for indemnification shall not exceed an amount equal to the Maximum Amount multiplied by such Seller’s Pro Rata Share; provided, however, that the Maximum Amount shall not apply to any fraudulent misrepresentation or the misrepresentation, breach or inaccuracy of any representation or warranty made by the Company in any of the following Sections: 3.1 (organization; authority; binding effect), 3.3 (capitalization), 3.7 (Taxes), and 3.17 (Indebtedness); provided, further, that the Maximum Amount shall not apply to any fraudulent misrepresentation or the misrepresentation, breach or inaccuracy of any representation or warranty made by a Seller in any of the following Sections: 4.1 (right to sell Units), 4.2 (title to Units), 4.4 (litigation); 4.5 (brokers) and 4.6 (investment intent).

               (c) All representations and warranties that are covered by the indemnification agreements in Section 13.1(a) and (b) shall (i) survive the Closing and (ii) shall expire on the date twelve months following the Closing Date, except that (1) the representations and warranties set forth in Sections 3.1, 3.3, 4.1, 4.2, 4.4 4.5 and 4.6 shall survive the Closing without limitation and (2) the representations and warranties set forth in Sections 3.7, and 3.17 shall survive until 30 days following expiration of all statutes of limitation applicable to the matters referred to therein (including any extensions of such statutes of limitation). All representations and warranties that are covered by the indemnification agreements in Section 13.2 shall (i) survive the Closing and (ii) shall expire on the date twelve months following the Closing Date, except that the representations and warranties set forth in Sections 5.1, 5.2 and 5.5 shall survive the Closing without limitation. If an Indemnified Party delivers to an Indemnifying Party, before expiration of a representation or warranty, a claim notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of any claims arising from or related to the matter covered by such notice. The rights to indemnification set forth in this Section 13 shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the date of this Agreement or the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an Indemnified Party of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

               (d) [Intentionally Omitted].

               (e) The amount of any Damages for which indemnification is provided under Section 10.3(c) or this Section 13 shall be net of (i) any amounts recovered by the Indemnified Party or its Affiliates as a result of any indemnification by any third party, and (ii) any insurance proceeds or other amounts received by the Indemnified Party or its Affiliates from third parties with respect to such Damages. If any such insurance proceeds and/or other amounts are received by the Indemnified Party after payment by any Indemnifying Party of any amount otherwise required to be paid to the Indemnified Party pursuant to Section 10.3(c) or this Section 13, the Indemnified Party shall repay to such Indemnifying Party, promptly after receipt of such insurance proceeds and/or other amounts, the amount that such Indemnifying Party would not have had to pay pursuant to this Section 13 had such insurance proceeds and/or other amounts been received by the Indemnified Party prior to such Indemnifying Party’s payment under this Section 13.

               (f) Any indemnification payments made by any of the Sellers pursuant to Section 10.3(c) or this Section 13 shall be treated by all parties as an adjustment to the Purchase Price hereunder.

          13.5. Expiration of Representations and Warranties; Scope of Sellers’ Liability. The Buyer and the Sellers acknowledge and agree that following the Closing, except with respect to claims based upon fraud and injunctive relief provided elsewhere and except as otherwise provided in this Agreement, the indemnification provided by Section 10.3 and Section 13 shall be the sole and exclusive remedy for any Damages of the Buyer or the Sellers with respect to this Agreement and any Exhibit or Schedule hereto or any certificate delivered hereunder. The Buyer and the Sellers acknowledge that this Section 13.5 has been negotiated fully by the Buyer and the Sellers and that the Buyer and the Sellers would not have entered into this Agreement but for the inclusion of this Section 13.5.

          13.6. Damages. Notwithstanding anything to the contrary contained herein, no party shall be entitled to claim, and each party hereby expressly waives any right to, any and all consequential, incidental, punitive and other special damages (regardless of legal theory).

          13.7. Set-Off Rights.

               (a) Buyer shall have a direct right of setoff against Buyer’s obligation to pay or issue the Subsequent Consideration to satisfy any indemnification obligations of the Sellers hereunder. To the extent that Buyer elects to pay any portion of the Subsequent Consideration in cash, any right of setoff pursuant to this Section 13.7 shall be first applied against such cash portion of the Subsequent Consideration, if any. To the extent that such cash portion of the Subsequent Consideration, if any, is insufficient to satisfy Buyer’s direct right of setoff, Buyer may setoff any remaining Damages against the Shares that would otherwise be issued as Subsequent Consideration.

For the purposes hereof, the number of Shares to be applied to any such obligation shall be a number equal to the amount of Damages divided by the greater of: (i) the product of the average closing price on NASDAQ for the Common Stock for the five (5) Business Days prior to Closing times 0.60; or (ii) the average closing price on NASDAQ for the Common Stock for the thirty (30) Business Days prior to prior to the date that is the earlier to occur of: (y) the date the Seller Representative delivers to the Buyer a Response that does not reflect a Dispute with respect to such Claim Notice and (z) the Triggering Date.

               (b) If the Buyer is entitled to be indemnified pursuant to Section 13.1(a) or (b) prior to the Triggering Date, then any Damages thereunder to be indemnified shall be satisfied solely by reducing the Subsequent Consideration to be issued or paid hereunder by the amount calculated pursuant to Section 13.7(a); provided, however, that the limitation to the right of setoff set forth in this Section 13.7(b) shall not apply to any Damages arising as a result of any fraudulent misrepresentation, or the misrepresentation, breach or inaccuracy of any of the Excluded Warranty Claims.

               (c) Notwithstanding any other provision of this Agreement, with respect to claims made pursuant to Sections 13.1(c)-(f), and in the case of any fraudulent misrepresentation and misrepresentations, breaches or inaccuracies of the Excluded Warranty Claims (other than misrepresentations, breaches or inaccuracies of the representations set forth in Section 3.7 and indemnification pursuant or relating to Section 10.3(c)), prior to the Triggering Date, the Buyer shall:

                    (i) look first to its direct right of setoff set forth in this Section 13.7 for recourse if and to the extent that there is sufficient unissued or unpaid Subsequent Consideration available to satisfy such claim, and

                    (ii) have recourse directly against the Sellers for amounts in excess of the actual dollar value of Damages recovered through the direct right of setoff set forth in this Section 13.7.

               (d) Notwithstanding any other provision of this Agreement, with respect to misrepresentations, breaches, or inaccuracies of the representations set forth in Section 3.7, and indemnification obligations of Sellers pursuant or relating to Section 10.3(c), the Buyer may, but shall not be obligated to, exercise its direct right of setoff set forth in this Section 13.7 before seeking recourse directly against the Sellers.

               (e) Notwithstanding any other provision of this Agreement, if a Dispute exists which has not been finally resolved as of the Triggering Date, Buyer shall be entitled to exercise its direct right of setoff against its obligation to issue or pay the Subsequent Consideration with respect to the aggregate Damages specified in such Claim Notice, pending final resolution of such Dispute.

               (f) In accordance with Section 13.4(f), indemnification payments made by reducing the amount of Deferred Consideration in accordance with this Section shall be treated by all parties as an adjustment to the Purchase Price hereunder.

          13.8. Sellers’ Pro Rata Share. Notwithstanding any other provision of this Agreement, in no event shall the maximum liability of any Seller under this Section 13 or Section 10.3(c) exceed such Seller’s Pro Rata Share of the Purchase Price.

          14. TERMINATION.

          14.1. Termination. This Agreement may be terminated at any time prior to Closing as follows:

               (a) By mutual written consent of the Buyer and the Seller Representative, on behalf of the Sellers;

               (b) In the event that the Closing does not occur on or before January 12, 2007, the Buyer may terminate this Agreement at any time after the close of business on such date by delivering a written notice to

the Seller Representative so long as such failure to close is not a result of a breach by the Buyer of any of its obligations hereunder;

               (c) In the event that the Closing does not occur on or before January 12, 2007, the Seller Representative, on behalf of the Sellers, may terminate this Agreement at any time after the close of business on such date by delivering a written notice to the Buyer so long as such failure to close is not a result of a breach by the Sellers of any of their (or the Company’s) respective obligations hereunder;

               (d) The Buyer may terminate this Agreement by written notice to the Seller Representative if any of the Sellers shall have breached any of their respective representations, warranties or obligations under this Agreement and such breach (i) individually or in combination with any other such breach, would cause the conditions set forth in Sections 7.1 or 7.2 not to be satisfied and (ii) is not cured within 20 days following delivery by the Buyer to the Seller Representative of written notice of such breach; or

               (e) The Seller Representative, on behalf of the Sellers, may terminate this Agreement by written notice to the Buyer if the Buyer shall have breached any of its representations, warranties or obligations under this Agreement and such breach (i) individually or in combination with any other such breach, would cause the conditions set forth in Sections 8.1 or 8.2 not to be satisfied and (ii) is not cured within 20 days following delivery by the Buyer to the Seller Representative of written notice of such breach.

          14.2. Effect of Termination. If the Buyer and the Seller Representative, on behalf of the Sellers, mutually consent to terminate this Agreement pursuant to Section 14.1(a) above, all rights and obligations of the parties hereunder shall terminate (other than the rights and obligations of the parties under Section 15.1) without any liability of any party to any other party. Any termination of this Agreement pursuant to Sections 14.1(b), (c), (d) or (e) above shall not relieve any party from any liability for any willful breach of such party’s obligations under this Agreement to any other party.

This Agreement contains the entire understanding of the parties, supersedes all prior agreements and understandings relating to the subject matter hereof (other than the Confidentiality and Non-Disclosure Agreement dated August 25, 2006, in favor of the Company) and shall not be amended except by a written instrument hereafter signed by the Buyer, the Company, and the Seller Representative.

          15.4. Governing Law. The validity and construction of this Agreement shall be governed by the internal Laws (and not the choice-of-law rules) of the State of Illinois.

          15.5. Sections and Section Headings. All enumerated subdivisions of this Agreement are herein referred to as “Section” or “paragraph.” The headings of Sections and paragraphs are for reference only and shall not limit or control the meaning thereof.

          15.6. Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. Neither this Agreement nor the obligations of any party hereunder shall be assignable or transferable by such party without the prior written consent of the other parties hereto, which consent shall not be unreasonably withheld; provided, however, that the Buyer may assign its

rights, but not its obligations, hereunder to any Person providing financing to the Buyer for the purchase of the Units hereunder.

          15.7. Further Assurances. The Sellers, the Company and the Buyer shall execute and deliver to all appropriate other parties such other instruments as may be reasonably required in connection with the performance of this Agreement and each shall take all such further actions as may be reasonably required to carry out the transactions contemplated by this Agreement.

          15.8. No Implied Rights or Remedies. Except as set forth in Section 10.2 and as otherwise expressly provided herein, nothing herein expressed or implied is intended or shall be construed to confer upon or to give any Person, firm or corporation, other than the Sellers, the Company and the Buyer and their respective shareholders, any rights or remedies under or by reason of this Agreement.

          15.9. [Intentionally Omitted].

          15.10. Counterparts; Facsimile Signatures. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile counter-part signatures to this Agreement shall be acceptable and binding.

          15.11. Enforceability of this Agreement; Satisfaction of Conditions Precedent. The Sellers and the Buyer will each use reasonable best efforts to cause the satisfaction of the conditions precedent contained in this Agreement; provided, however, that nothing contained in this Section 15.11 shall obligate any party hereto to waive any right or condition under this Agreement. Except as otherwise provided by this Agreement, the Buyer’s obligation to pay the Deferred Consideration pursuant to Section 1.2(d) is specifically enforceable at the election of the Seller Representative, and Buyer agrees that it shall reimburse the Seller Representative for any and all fees, costs and expenses (including fees and expenses of counsel) reasonably incurred by the Seller Representative in enforcing such obligation.

          15.12. Public Statements or Releases. Except as otherwise required by applicable Law, each of the parties hereto agrees that prior to the Closing no party to this Agreement will make, issue or release any public announcement, statement or acknowledgment of the existence of, or reveal the status of, this Agreement, the transactions contemplated hereby or any negotiations or discussions related hereto, without first obtaining the prior consent of the other parties hereto. Each of the parties hereto further agrees to provide written notice to the other parties to this Agreement, promptly upon the knowledge thereof, of any obligation under applicable Law to make, issue or release any such public announcement, statement or acknowledgment.

          15.13. Business Records. The Buyer acknowledges that the business records of the Company relating to its operations prior to Closing will be acquired by the Buyer in connection with the consummation of the transactions contemplated hereby, and that the Sellers may from time to time require access to or copies of such records. The Buyer agrees that upon reasonable prior notice from any Seller, it will, during normal business hours, provide such Seller with access to or copies of such records. Each Seller hereby agrees to hold any confidential information so provided in confidence and to use such information only for the purposes described above. The Buyer agrees that it will not within six (6) years after the Closing Date destroy any business records of the Company prepared prior to the Closing without first notifying the Seller Representative, and affording the Seller Representative the opportunity to remove or copy such records. For purposes of the preceding sentence, any notice from the Buyer delivered in accordance with Section 15.2 shall be deemed to be adequate notice if not responded to in writing by the Seller Representative within ninety (90) days.

          15.14. Seller Representative. By the execution and delivery of this Agreement, each of the Sellers hereby irrevocably constitutes and appoints ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇ as the true and lawful agent and attorney-in-fact (the “Seller Representative”) of the Sellers with full power of substitution to act in the name, place and stead of the Sellers with respect to the transfer of the Shares owned by the Sellers to the Buyer in accordance with the terms and provisions of this Agreement, and to act on behalf of the Sellers in any litigation or arbitration involving this Agreement, to do or refrain from doing all such further acts and things, and to execute all such documents as the Seller Representative shall deem necessary or appropriate in connection with the transactions contemplated by this Agreement, including, without limitation, the power:

               (a) to act for the Sellers with regard to matters pertaining to indemnification referred to in this Agreement, including the power to compromise any indemnity claim on behalf of the Sellers and to transact matters of litigation;

               (b) to execute and deliver all amendments, waivers, ancillary agreements, stock powers, certificates and documents that the Seller Representative deems necessary or appropriate in connection with the consummation of the transactions contemplated by this Agreement;

               (c) to execute and deliver all amendments and waivers to this Agreement that the Seller Representative deems necessary or appropriate, whether prior to, at or after the Closing;

               (d) to receive funds, make payments of funds, and give receipts for funds;

               (e) to receive funds for the payment of expenses of the Sellers and apply such funds in payment for such expenses;

               (f) to do or refrain from doing any further act or deed on behalf of the Sellers that the Seller Representative deems necessary or appropriate in its sole discretion relating to the subject matter of this Agreement as fully and completely as the Sellers could do if personally present; and

               (g) to receive service of process in connection with any claims under this Agreement.

     The appointment of the Seller Representative shall be deemed coupled with an interest and shall be irrevocable, and the Buyer and any other Person may conclusively and absolutely rely, without inquiry, upon any action of the Seller Representative in all matters referred to herein. All notices required to be made or delivered by the Buyer to the Sellers described above in this Section 15.14 shall be made to the Seller Representative for the benefit of the Sellers and shall discharge in full all notice requirements of the Buyer to the Sellers with respect thereto. The Sellers hereby confirm all actions that the Seller Representative shall do or cause to be done by virtue of its appointment as the Seller Representative of the Sellers. The Seller Representative shall act for the Sellers on all of the matters set forth in this Agreement in the manner the Seller Representative believes to be in the best interest of the Sellers and consistent with the obligations under this Agreement, but the Seller Representative shall not be responsible to the Sellers for any loss or damages the Sellers may suffer by the performance of its duties under this Agreement, other than loss or damage arising from willful violation of Law or gross negligence in the performance of its duties under this Agreement. Sellers agree jointly and severally to indemnify, defend and hold harmless the Seller Representative from and against any and all loss, damage, liability and expense that may be incurred by the Seller Representative arising out of or in connection with its appointment as Seller Representative under this Agreement (except such as may result from the Seller Representative’s willful violation of Law or gross negligence in the performance of its duties under this Agreement), including the legal costs of defending itself against any claim or liability in connection with its performance under this Agreement and all other documents and agreements executed and delivered by the Seller Representative in connection with this Agreement. The Seller Representative, each Seller and the Buyer expressly acknowledge that the Seller Representative shall have no authority or responsibility to act on behalf of any Seller in connection with any claim, action or proceeding initiated against such Seller pursuant to a breach by such Seller of Such Seller’s individual representations, warranties or covenants hereunder.

          15.15. [Intentionally Omitted].

          15.16. Interpretation; Exhibits and Schedules. The words “include”, “includes” and “including” are deemed to be followed by the phrase “without limitation”. Any references to the masculine, feminine, or neuter gender shall include such other genders and any references to the singular or plural shall include the other, in each case unless the context otherwise requires. All Exhibits and the Disclosure Schedule annexed hereto or referred to herein are hereby incorporated in and made part of this Agreement as if set forth in full herein.

          15.17. Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives any and all right to trial by jury of any claim or cause of action in any legal proceeding arising out of or related to this

Agreement or the transactions or events contemplated hereby or any course of conduct, course of dealing, statements (whether verbal or written), or actions of any party hereto. The parties hereto each agree that any and all such claims and causes of action shall be tried by the court without a jury. Each of the parties hereto further waives any right to seek to consolidate any such legal proceeding in which a jury trial has been waived with any other legal proceeding in which a jury trial cannot or has not been waived.

     IN WITNESS WHEREOF, and intending to be legally bound hereby, the parties hereto have caused this Unit Purchase Agreement to be duly executed and delivered as of the date and year first above written.
