The execution and delivery of this Agreement, the issuance and sale of the Shares to be sold by the Company under this Agreement, the fulfillment of the terms of this Agreement by the Company and the Company’s consummation of the transactions contemplated hereby will not (A) conflict with or constitute a violation of, or default (with or without the giving of notice or the passage of time or both) under, (i) any material bond, debenture, note or other evidence of indebtedness, or under any material lease, indenture, mortgage, deed of trust, loan agreement, joint venture or other agreement or instrument to which the Company or a Subsidiary is a party or by which the Company or a Subsidiary or their respective properties are bound (each, a “Material Contract”), (ii) the charter, bylaws or other organizational documents of the Company or the Subsidiaries or (iii) to the knowledge of the Company, any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority applicable to the Company or a Subsidiary or their respective properties or (B) result in the creation or imposition of any lien, encumbrance, claim, security interest or restriction upon any of the material properties or assets of the Company or a Subsidiary or an acceleration of indebtedness pursuant to any obligation, agreement or condition contained in any material bond, debenture, note or any other evidence of indebtedness or any material indenture, mortgage, deed of trust or any other agreement or instrument to which the Company or a Subsidiary is a party or by which any of them is bound or to which any of the property or assets of the Company or a Subsidiary is subject.

For purposes of this Agreement, the “Registration Termination Date” shall be the later of (x) the two- (2)-year anniversary of the Closing Date, and (y) the date that all of the Shares become eligible for sale pursuant to Rule 144 during any one (1) ninety- (90)-day period;

The Company shall, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties);

(g) advise the Investor, within two (2) business days by electronic mail, facsimile or other electronic or non-electronic means of communication, and, if requested by the Investor, confirm such advice in writing: (i) after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation or threat of any proceeding for that purpose, or any other order issued by any state securities commission or other regulatory authority suspending the qualification or exemption from qualification of such Shares under state securities, or “blue sky,” laws; and it shall promptly use its reasonable best efforts to prevent the issuance of any stop order or other order or to obtain its withdrawal at the earliest possible moment if such stop order or other order should be issued and (ii) when the Prospectus or any supplements to or amendments of the Prospectus have been filed, and, with respect to the Registration Statement or any post effective amendment thereto, when the same has become effective; and

(i) in the event the Registration Statement has not been filed with the SEC within thirty (30) days after the Registration Demand Date, the Investor shall be entitled to receive from the Company liquidated damages in an amount equal to one percent (1.0%) of the total aggregate purchase price of the Shares that are to be registered on such Registration Statement (a “Liquidated Damages Payment”);

(ii) in the event the Registration Statement has not been filed with the SEC within sixty (60) days after the Registration Demand Date, the Investor shall be entitled to receive from the Company an additional Liquidated Damages Payment;

(iii) in the event the Registration Statement has not been declared effective by the SEC within ninety (90) days after the Registration Demand Date, the Investor shall be entitled to receive an additional Liquidated Damages Payment; and

(b) Liquidated Damages Payments may, at the Investor’s option, be delivered to the Investor in the form of cash or Common Stock. The Company shall deliver all Liquidated Damages Payments to the Investor by the fifth (5^th) business day after the occurrence of the events described in clauses (i), (ii), (iii) or (iv) of Section 7.2(a) hereof, as applicable.

(c) Notwithstanding anything to the contrary contained in this Section 7.2 or in any other provision of this Agreement, the Liquidated Damages Payments provided in this Section 7.2 shall be the Investor’s sole and exclusive monetary remedy in the event of the occurrence of any of the events described in clauses (i), (ii), (iii) or (iv) of Section 7.2(a) hereof; provided, however, that the Investor shall retain all equitable remedies then available to it.

7.3 Transfer of Shares; Suspension.

(a) The Investor agrees that it shall not effect any sale, offer to sell, solicitation of offers to buy, disposition of, loan, pledge or grant of any right with respect to the Shares or any derivative instruments, arrangement or securities the value of which is derived from the securities of the Company or its right to purchase any securities of the Company or any derivative instruments, arrangement or securities the value of which is derived from the securities of the Company that would constitute a sale within the meaning of the Securities Act, except as contemplated in the Registration Statement referred to in Section 7.1(a) hereof or in accordance with the Securities Act (including any exemption from the registration requirements set forth therein), and that it shall promptly notify the Company of any changes in the

information set forth in the Registration Statement regarding the Investor or its plan of distribution.

(b) Except in the event that Section 7.3(c) hereof applies, the Company shall, at all times during the Registration Period, promptly:

(i) prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain 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, and so that, as thereafter delivered to purchasers of the Shares being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(ii) provide the Investor copies of any documents filed pursuant to Section 7.3(b)(i) hereof; and

(iii) inform the Investor that the Company has complied with its obligations in Section 7.3(b)(i) hereof (or that, if the Company has filed a post-effective amendment to the Registration Statement that has not yet been declared effective, the Company shall notify the Investor to that effect, shall use its commercially reasonable efforts to secure the effectiveness of such post-effective amendment as promptly as possible and shall promptly notify the Investor pursuant to this Section 7.3(b)(iii) when the amendment has become effective).

(c) Subject to Section 7.3(d) hereof, in the event of:

(i) any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to a Registration Statement or related Prospectus or for additional information;

(ii) the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose;

(iii) the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; or

(iv) any event or circumstance that necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will 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 not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state

a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading,

then the Company shall deliver a notice in writing to the Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor shall refrain from selling any Shares pursuant to the Registration Statement (a “Suspension”) until the Investor’s receipt of copies of a supplemented or amended Prospectus prepared and filed by the Company, or until it is advised in writing by the Company that the current Prospectus may be used. In the event of any Suspension, the Company shall use its commercially reasonable efforts, consistent with the best interests of the Company and its stockholders, to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after the delivery of a Suspension Notice to the Investor.

(d) In the event the Investor is prohibited from selling Shares under the Registration Statement as a result of Suspensions for more than sixty (60) days in any twelve- (12)-month period, then (i) the Company shall pay to the Investor liquidated damages in an amount equal to one percent (1.0%) of the total aggregate purchase price of the Shares registered on such Registration Statement then held by the Investor if, as a result of such Suspensions, the Investor is prohibited from selling Shares under such Registration Statement for a period that exceeds sixty (60) days in the aggregate in any twelve- (12)-month period and (ii) after the date, if any, on which the Company becomes obligated to pay the Investor liquidated damages pursuant to the preceding clause (i), the Company shall pay to the Investor additional liquidated damages in an amount equal to one percent (1.0%) of the total aggregate purchase price of the Shares registered on such Registration Statement then held by the Investor for each additional thirty (30) days thereafter during which as a result of a suspension the Investor is prohibited from selling shares under such Registration Statement; provided, however, that in no event shall the Company be obligated to pay more than one percent (1.0%) of the total aggregate purchase price of the Shares registered on such Registration Statement then held by the Investor in any thirty- (30)-day period.

(e) In the event of a sale of Shares by the Investor under the Registration Statement, the Investor must also deliver to the Company’s transfer agent, with a copy to the Company, a Certificate of Subsequent Sale substantially in the form attached hereto as Exhibit E, so that the Shares may be properly transferred.

7.4 Indemnification. For the purpose of this Section 7.4, the term “Registration Statement” shall include the Prospectus, any preliminary or final prospectus, exhibit, supplement or amendment included in or relating to the Registration Statement referred to in Section 7.1 hereof, and the term “Rules and Regulations” shall mean the rules and regulations promulgated under the Securities Act.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless the Investor, the officers and directors of the Investor and any Person, if any, who controls the Investor within the meaning of the Securities Act (collectively, the “Investor Indemnitees”), against any losses, claims, damages, liabilities or expenses to which the Investor Indemnitees may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation insofar as such losses, claims, damages,

liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon:

(i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including the Prospectus, financial statements and schedules, and all other documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A, or pursuant to Rule 434 of the Rules and Regulations, or the Prospectus, in the form first filed with the SEC pursuant to Rule 424(b) of the Rules and Regulations, or filed as part of the Registration Statement at the time of effectiveness if no Rule 424(b) filing is required (the “Prospectus”), or any amendment or supplement thereto;

(ii) the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading; or

(iii) any failure of the Company to perform its obligations under this Agreement, and shall reimburse the Investor Indemnitees for any legal and other expenses as such expenses are reasonably incurred by the Investor Indemnitees in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action;

provided, however, that the Company shall not be liable in any such case (a) to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement of the Registration Statement or Prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Investor expressly for use in the Registration Statement or the Prospectus, (ii) the failure of the Investor to comply with the covenants and agreements contained in Section 7.3 hereof respecting resale of the Shares or (iii) any untrue statement or omission of a material fact in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Investor before the pertinent sale or sales by the Investor or (b) for any amount paid in settlement of any such loss, claim, damage, liability, expense or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld.

(b) Indemnification by the Investor. The Investor agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who sign the Registration Statement and each Person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages, liabilities or expenses to which the Company, each of its directors, each of its officers who sign the Registration Statement or controlling Person may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon:

(i) any failure on the part of the Investor to comply with the covenants and agreements contained in Section 7.3 hereof respecting the sale of the Shares; or

(ii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement to the Registration Statement or Prospectus, or the 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 under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Investor expressly for use therein;

provided, however, that the Investor shall not be liable for (a) any such untrue or alleged untrue statement or omission or alleged omission of which the Investor has delivered to the Company in writing a correction at least five (5) business days before the occurrence of the transaction from which such loss was incurred, and the Investor shall reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling Person for any legal and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling Person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action for which such Person is entitled to be indemnified in accordance with this Section 7.4(b) or (b) any amount paid in settlement of any such loss, claim, damage, liability, expense or action if such settlement is effected without the consent of the Investor, which consent shall not be unreasonably withheld.

(c) Indemnification Procedure.

(i) Promptly after receipt by an indemnified party under this Section 7.4 of notice of the threat or commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 7.4, promptly notify the indemnifying party in writing of the claim; but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 7.4 except to the extent it is materially prejudiced as a result of such failure.

(ii) In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party shall be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be a conflict between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action

on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action, the indemnifying party shall not be liable to such indemnified party under this Section 7.4 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless:

(1) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the first sentence of clause (ii) above (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one (1) separate counsel, approved by such indemnifying party representing all of the indemnified parties who are parties to such action); or

(2) the indemnifying party shall not have counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. Notwithstanding the provisions of this Section 7.4, (A) with respect to claims made pursuant to clause (i) of Section 7.4(b) hereof, the Investor shall not be liable for any indemnification obligation under this Agreement in excess of the amount of net proceeds received by the Investor from the sale of the Shares and (B) with respect to claims made pursuant to clause (ii) of Section 7.4(b) hereof, the Investor shall not be liable for any indemnification obligation under this Agreement in excess of the amount of net proceeds received by the Investor from the sale of the Shares giving rise to such liability.

(d) Contribution.

(i) If a claim for indemnification under this Section 7.4 is unavailable to an indemnified party (by reason of public policy or otherwise), then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to in this Agreement, in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions, statements or omissions that resulted in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any losses, claims, damages, liabilities or expenses shall be deemed to include, subject to the limitations set forth in this Section 7.4, 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 7.4 was available to such party in accordance with its terms.

(ii) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7.4 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 7.4, (A) with respect to claims made pursuant to clause (i) of Section 7.4(b) hereof, the Investor shall not be liable to contribute any amount in excess of the amount of net proceeds received by the Investor from the sale of the Shares and (B) with respect to claims made pursuant to clause (ii) of Section 7.4(b) hereof, the Investor shall not be liable to contribute any amount in excess of (x) the amount by which the net proceeds received by the Investor from the sale of the Shares giving rise to such liability exceeds (y) the amount of any damages that the Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No party to this Agreement guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any other party to this Agreement who was not guilty of such fraudulent misrepresentation.

7.5 Termination of Conditions and Obligations. The restrictions imposed by Section 7.3 hereof upon the transferability of the Shares shall cease and terminate as to any particular number of Shares upon the Registration Termination Date or at such time as an opinion of counsel satisfactory in form and substance to Parent shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act. Notwithstanding the foregoing, it is expressly understood that no such opinion of counsel shall be required if the Company shall be furnished with written documentation reasonably satisfactory to it that such Shares are being transferred in a customary transaction exempt from registration under Rule 144 under the Securities Act.

Section 8. Company Covenants.

8.1 Rule 144. For a period commencing on the date hereof and ending on the date on which the Investor may sell all of the Shares pursuant to Rule 144(k) under the Securities Act, the Company agrees with the Investor to:

obligations with respect to confidential or proprietary information of third parties or comply with applicable law.

The Investor acknowledges that there may occasionally be times when the Company, based on the advice of its counsel, determines that, subject to the limitations of Section 7.3 hereof, it must suspend the use of the Prospectus forming a part of the Registration Statement until such time as an amendment to the Registration Statement has been filed by the Company and declared effective by the SEC or until the Company has amended or supplemented such Prospectus.

(a) Should the Investor propose to accept one or more bona fide offers from any Persons identified on Exhibit F attached hereto as a Restricted Party for purposes of this Section 9.3 and such Persons’ affiliates (each, a “Restricted Party”) to purchase from the Investor a number of shares of Common Stock that exceeds five percent (5%) of the Common Stock outstanding as shown by the then-most-recent report or statement by the Company in any single transaction or series of related transactions occurring within a 180-day period (collectively, a “Purchase Offer”), the Investor, prior to accepting any such Purchase Offer, shall promptly deliver a written notice (the “Notice of Sale”) to the Company stating the terms and conditions of such Purchase Offer on which the Investor in good faith believes a binding agreement is obtainable, including, without limitation, the number of shares of Common Stock proposed to be sold or transferred (the “Offered Shares”), the nature of such sale or transfer, the consideration to be paid and the name and address of each prospective purchaser or transferee. The Notice of Sale shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the Purchase Offer.

(b) The Company shall have an option for thirty (30) business days after receiving the Notice of Sale to deliver written notice (the “Reply Notice”) to the Investor of its election to purchase all, or any portion of, the Offered Shares at the price and upon the terms specified in the Notice of Sale.

(c) In the event that the Company through delivery of its Reply Notice elects not to purchase all, or any portion of, the Offered Shares, then and only then shall the

Investor be free to consummate the transactions contemplated by the Purchase Offer with respect to that portion of the Offered Shares not purchased by the Company; provided, however, that if such transactions are not consummated within ninety (90) days of the date of the Reply Notice, the Investor shall again comply with all of the provisions of this Section 9.3.

(d) The rights of the Company set forth in this Section 9.3 shall be assignable by the Company to any Person in the complete and exclusive discretion of the Company.

(e) Additional Restricted Parties may be identified by the Company after the date of this Agreement only upon the written consent of the Investor, which consent shall not be unreasonably withheld.

(f) For purposes of clarity, the parties hereto acknowledge that the provisions of this Section 9.3 are not intended to apply to any sale of Shares by the Investor in any open market transaction conducted through a broker/dealer.

(g) The restriction set forth in this Section 9.3 shall terminate on the two- (2)-year anniversary of the Closing Date.

10.3 Amendments and Waivers. No provision of this Agreement may be amended or waived except in a written instrument signed, in the case of an amendment, by the Company and the Investor or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

10.4 Headings. The headings of the various sections of this Agreement have been inserted for convenience of reference only and shall not be deemed to be part of this Agreement.

10.5 Severability. In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, and

the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

10.6 Governing Law. This Agreement shall be governed by, and construed in accordance with, the internal law of the State of California without regard to conflict of law principles that would result in the application of any law other than the law of the State of California.

10.7 Entire Agreement. This Agreement and that certain Confidentiality Agreement, dated February 22, 2006, by and between the Company and the Investor (the “Confidentiality Agreement”) constitute the entire agreement between the parties hereto pertaining to the subject matter hereof, and any and all other written or oral agreements relating to such subject matter are expressly cancelled. Notwithstanding the foregoing, the entire paragraph beginning at the bottom of page three (3) of the Confidentiality Agreement and continuing through the middle of page four (4) of the Confidentiality Agreement, beginning with the clause “In consideration of the Evaluation Material being furnished hereunder” is hereby superseded by this Agreement and is of no further force or effect.

10.8 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other parties.

10.9 Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the Investor, including without limitation and without the need for an express assignment, affiliates of the Investor. With respect to transfers that are not made pursuant to the Registration Statement, the rights and obligations of the Investor under this Agreement shall be automatically assigned by such Investor to any transferee of all or any portion of such Investor’s Shares who is a Permitted Transferee (as defined below); provided, however, that within two business days prior to the transfer, (i) the Company is provided notice of the transfer including the name and address of the transferee and the number of Shares transferred and (ii) that such transferee agrees in writing to be bound by the terms of this Agreement. (For purposes of this Agreement, a “Permitted Transferee” shall mean any Person who (a) is an “accredited investor,” as that term is defined in Rule 501(a) of Regulation D under the Securities Act and (b) is a transferee of at least 250,000 Shares as permitted under the securities laws of the United States). Upon any transfer permitted by this Section 10.9, the Company shall be obligated to such transferee to perform all of its covenants under this Agreement as if such transferee were an Investor.

10.10 Expenses. Each of the Company and the Investor shall bear its respective legal, accounting, advisory and other fees, and all other out-of-pocket expenses in connection with the preparation and negotiation of this Agreement; provided, however, that if the Closing occurs, the Company shall reimburse the Investor for its legal and advisory fees actually incurred up to a maximum aggregate amount of fifty thousand dollars ($50,000).

10.11 Arbitration.

(a) The parties hereto agree that any dispute, controversy or claim arising out of or relating to this Agreement, or breach thereof (“Dispute”), shall be subject to a mandatory period of thirty (30) days during which the parties shall (i) each appoint a representative (each a “Representative” and collectively, the “Representatives”) and (ii) the Representatives shall meet in a timely manner for the purpose of attempting to resolve the Dispute. The Representatives shall negotiate in good faith to resolve the Dispute without resort to formal proceedings. During the course of such negotiations, the parties shall comply with all reasonable requests for access to relevant information. Formal proceedings for the arbitration of such Dispute may not be commenced until the expiration of the foregoing mandatory thirty- (30)-day period. Both parties shall continue to perform their respective obligations hereunder during the negotiations by Representatives attempting to resolve the Dispute.

(b) Following the expiration of the mandatory thirty- (30)-day period provided in Section 10.11(a) hereof, any unresolved Dispute shall be settled by arbitration administered by the American Arbitration Association (“AAA”) under its Commercial Dispute Resolution Procedures, and judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

(c) The parties agree to the arbitration of the Dispute by a single arbitrator appointed in accordance with the rules and procedures of the American Arbitration Association.

(d) The parties agree to appropriate discovery, including depositions, under the jurisdiction of the arbitrator. The arbitrator’s decision in such matters shall be final and binding on the parties.

(e) The parties agree that the arbitrator may grant any remedy or relief that the arbitrator deems just and equitable within the scope of the agreement between the parties, including but not limited to the award of compensatory damages and ordering the specific performance of the contract, but not including the award of exemplary or punitive damages.

(f) The parties hereby agree that, notwithstanding the fact that applicable law may not provide for the award of attorneys’ fees and costs and/or otherwise grant the arbitrator the discretion to award such fees and costs, pursuant to this Agreement, the arbitrator may, in his or her reasonable discretion, award payment of attorneys’ fees and costs by a party as a part of the arbitration award rendered by the arbitrator.
