5.4 The Purchaser understands that its investment in the Shares involves a significant degree of risk and that the market price of the Common Stock has been and continues to be volatile and that no representation is being made as to the future value of the Common Stock. The Purchaser has the knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares and has the ability to bear the economic risks of an investment in the Shares. The Purchaser has been afforded the opportunity to ask questions of the Company regarding such matters and acknowledges that neither such inquiries nor any other due diligence investigation conducted by the Purchaser or any of its advisors or representatives modifies, amends or affects the Purchaser’s right to rely on the Company’s representations and warranties contained in Section 4 above.

5.5 The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Shares.

5.6 The Purchaser understands that, until such time as the Registration Statement has been declared effective or the Shares may be sold by non-affiliates of the Company pursuant to Rule 144 under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Shares will bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the certificates for the Shares):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTION. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN FORM, SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT.”

The Company agrees to reissue certificates representing any of the Shares, without the legend set forth above, if Purchaser shall make a written request to the Company; provided that such legend will not be removed until: (a) the Company has notified such Purchaser that either (i) in the opinion of Company counsel, the registration of the Shares under the Securities Act is not required in connection with such proposed transfer; or (b) the Company has notified such Purchaser that either (i) in the opinion of Company counsel, the registration or qualification under the securities or Blue Sky laws of any state is not required in connection with such proposed disposition, or (ii) compliance with applicable state securities or Blue Sky laws has been effected. The Company will respond to any such notice from Purchaser within three (3) business days.

5.7 The Purchaser’s principal executive offices are in the jurisdiction set forth immediately below the Purchaser’s name on the signature pages hereto.

5.8 The Purchaser hereby covenants with the Company not to make any sale of the Shares under the Registration Statement without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied, and the Purchaser acknowledges and agrees that such Shares are not transferable on the books of the Company unless the certificate submitted to the Transfer Agent evidencing the Shares is accompanied by a separate Purchaser’s Certificate of Subsequent Sale (i) in the form of Appendix II hereto, (ii) executed by an officer of, or other authorized person designated by, the Purchaser, and (iii) to the effect that (A) the Shares have been sold in accordance with the Registration Statement, the Securities Act

and any applicable state securities or Blue Sky laws and (B) if applicable, the requirement of delivering a current prospectus has been satisfied. The Purchaser acknowledges that there may occasionally be times when the Company must suspend the use of the prospectus forming a part of the Registration Statement (a “Suspension”) until such time as an amendment to the Registration Statement has been filed by the Company and declared effective by the SEC, or such time as such prospectus has been supplemented, or until such time as the Company has filed an appropriate report with the SEC pursuant to the Exchange Act. The Purchaser hereby covenants that it will not sell any Shares pursuant to said prospectus during the period commencing at the time at which it receives written notice of the Suspension of the use of said prospectus (without providing any other material information other than at the written request of the Purchaser) and ending at the time the Company gives the Purchaser written notice that the Purchaser may thereafter effect sales pursuant to said prospectus. The Purchaser shall not be prohibited from selling Shares under the Registration Statement as a result of Suspensions on more than two (2) occasions of not more than thirty (30) days each in any 12-month period, unless, in the good faith judgment of the Company’s Board of Directors following the written advice of counsel, the sale of Shares under the Registration Statement in reliance on this paragraph would be reasonably likely to cause a violation of the Securities Act or the Exchange Act.

5.9 The Purchaser further represents and warrants to, and covenants with, the Company that (i) the Purchaser has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement; (ii) upon the execution and delivery of this Agreement, this Agreement shall constitute a legal, valid and binding obligation of the Purchaser, enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as the indemnification agreements of the Purchaser in Section 7.3 hereof may be legally unenforceable; (iii) the execution, delivery and performance of this Agreement by the Purchaser and the consummation by the Purchaser of the transactions contemplated hereby will not (A) conflict with or result in a violation of any provision of the Purchaser’s certificate of incorporation or other organizational document, or (B) violate or conflict with, or result in a breach of any provision of, or constitute a default under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or other instrument to which the Purchaser is a party, or (C) result in a violation of any law, rule, regulation, order, judgment or decree applicable to the Purchaser, except any such violation that would not have a Material Adverse Effect on the ability of the Purchaser to consummate the transactions contemplated by the Agreement; (iv) the Purchaser is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency or any regulatory or self-regulatory agency in order for it to execute, deliver or perform any of its obligations under this Agreement in accordance with the terms hereof, except for such consents, authorizations, orders, filings or registrations that have already been obtained; (v) the Purchaser has no present intent to consummate a “change of control” of the Company, as such term is understood in Rule 13d of the Exchange Act; (vi) the Purchaser is not a party to any litigation against the Company; and (vii) the Purchaser understands that nothing in this

Agreement or any other materials presented to the Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Purchaser has consulted its own legal, tax and investment advisors, as it, in its sole discretion, has deemed necessary or appropriate in connection with the purchase of the Shares.

5.10 The Purchaser acknowledges the following disclosure, which is set forth herein as required pursuant to Section 25102(a) of the California Corporate Securities Law of 1968:

“THE SALE OF THE SECURITIES THAT ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.”

SECTION 6. Survival of Representations and Warranties. Notwithstanding any investigation made by any party to this Agreement or by the Placement Agent, all representations and warranties made by the Company and the Purchaser herein shall survive the execution of this Agreement, the delivery to the Purchaser of the Shares being purchased and the payment therefor for a period of one year from the Closing Date.

SECTION 7. Registration of the Shares; Compliance with the Securities Act.

7.1 Registration Procedures and Expenses. The Company shall:

(a) subject to receipt of necessary information in writing from the Purchasers, as soon as reasonably practicable, but in no event later than thirty (30) calendar days following the Closing Date (the “Filing Date”), prepare and file with the SEC a Registration Statement on Form S-3 relating to the sale of the Shares by the Purchaser and the Other Purchasers from time to time on the Nasdaq or the facilities of any national securities exchange on which the Common Stock is then traded or in privately negotiated transactions (the “Registration Statement”). If Form S-3 is not available at that time, as soon as practicable considering the form being used, the Company will file a registration statement or such form as is then available to effect a registration of the Shares, subject to the consent of the Purchasers holding a majority of the Shares actually sold in the Offering, which consent shall not be unreasonably withheld;

(b) use its commercially reasonable efforts, subject to receipt of necessary information from the Purchasers, to cause the SEC to declare the Registration Statement effective within ninety (90) calendar days after the Closing Date (the “Required Effective Date”). However, so long as the Company filed the Registration Statement by the Filing Date, if

the Registration Statement receives SEC review, then the Required Effective Date will be the one hundred fiftieth (150th) calendar day after the Closing Date. The Company’s reasonable commercial efforts will include, but not be limited to, as soon as practicable responding to all comments received from the staff of the SEC. If the Company receives notification from the SEC that the Registration Statement will receive no action or review from the SEC, then the Company will, subject to its rights under this Agreement and its ability to request acceleration of effectiveness, use its commercially reasonable efforts to cause the Registration Statement to become effective within five (5) business days after such SEC notification;

(c) use its commercially reasonable efforts to promptly prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective until the earliest of (i) two (2) years after the Closing Date, (ii) the date on which the Purchasers may sell all of the Shares then held by the Purchasers, without registration, pursuant to Rule 144(k) of the Securities Act or (iii) such time as all Shares purchased by all Purchasers in the Offering have been sold pursuant to a Registration Statement or Rule 144 of the Securities Act. Thereafter, the Company shall be entitled to withdraw the Registration Statement and the Purchasers shall have no further right to offer or sell any of the Shares pursuant to the Registration Statement;

(d) notify each Purchaser in writing promptly as to any request for acceleration of the effectiveness of the Registration Statement and furnish to the Purchaser with respect to the Shares registered under the Registration Statement (and to each underwriter, if any, of such Shares) such number of copies of prospectuses and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares by the Purchaser;

(e) file documents required of the Company for normal Blue Sky clearance in states specified in writing by the Purchaser and reasonably acceptable to the Company; provided, however, that the Company shall not be required to (i) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 7.1; (ii) file a general consent to service of process in any such jurisdiction; (iii) subject itself to taxation in any such jurisdiction; (iv) provide any undertakings that cause material expense or burden to the Company; or (v) make any change to its organizational documents; and

(f) bear all expenses in connection with the procedures in paragraphs (a) through (e) of this Section 7.1 and the registration of the Shares pursuant to the Registration Statement, other than fees and expenses, if any, of counsel or other advisers to the Purchaser or the Other Purchasers or underwriting discounts, brokerage fees, commissions, and other selling expenses incurred by the Purchaser or the Other Purchasers, if any.

Notwithstanding the foregoing, it shall be a condition precedent to the obligations of the Company to take any action pursuant to paragraphs (a) through (f) of this Section 7.1, that the Purchaser shall furnish to the Company such information regarding itself, the Shares to be sold by the Purchaser, and the intended method of disposition of such Shares as shall be required to effect the registration of the Shares, all of which information shall be furnished to the Company in writing specifically for use in the Registration Statement.

The Company understands that the Purchaser disclaims being an underwriter, but the Purchaser being deemed an underwriter shall not relieve the Company of any obligations it has hereunder. Notwithstanding the foregoing, the parties understand and agree that the Company shall not be obligated to retain an underwriter with respect to the offer and sale of Shares pursuant to the Registration Statement.

The Company shall promptly notify the Purchaser of the effectiveness of the Registration Statement, and any post-effective amendments thereto, as well as of the receipt by the Company of any stop orders of the SEC with respect to the Registration Statement and the lifting of any such order.

7.2 Transfer of Shares After Registration. While the Registration Statement is effective and available for resale, the Purchaser agrees that it will not effect any disposition of the Shares or its right to purchase the Shares 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 hereof in the section titled “Plan of Distribution” or pursuant to an applicable exemption from registration, the availability of which is confirmed in writing by counsel to the Purchaser (the form, substance and scope of which opinion shall be reasonably acceptable to the Company) and delivered to the Company, and that it will promptly notify the Company of any changes in the information set forth in the Registration Statement regarding the Purchaser or its plan of distribution.

7.3 Indemnification.

(i) For Purpose of this Agreement, the term “Purchaser/Affiliate” shall mean any affiliate of the Purchaser (as defined in Rule 405 under the Securities Act) and any person who controls the Purchaser or any affiliate of the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and

(ii) For purpose of this Section 7.3, the term “Registration Statement” shall include any final prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement referred to in Section 7.1 hereof.

(a) The Company agrees to indemnify and hold harmless the Purchaser and each Purchaser/Affiliate against any losses, claims, damages, liabilities or expenses, joint or several, to which the Purchaser or Purchaser/Affiliate may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon 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, or arise out of or are based upon 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 the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in the light of the circumstances under which they were made, or arise out of or are based in whole or in part on any material breach of the representations and warranties of the Company contained in this Agreement, or any material breach by the Company of its obligations hereunder, and will reimburse the Purchaser or Purchaser/Affiliate for any legal and other expenses as such expenses are reasonably incurred by the Purchaser or Purchaser/Affiliate in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable in any such case to the extent, but only 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 thereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, or (ii) the failure of the Purchaser to comply with the covenants and agreements contained in Section 5(h) or Section 7.2 hereof respecting the sale of the Shares, or (iii) the inaccuracy of any representations made by the Purchaser herein or (iv) any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by the Purchaser.

(b) The Purchaser will severally, but not jointly, indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities or expenses to which the Company, each of its directors, each of its officers who signed 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, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Purchaser) 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 to comply with the covenants and agreements contained in Sections 5(h) or 7.2 hereof respecting the sale of the Shares or (ii) any material breach of any representation made by the Purchaser herein or (iii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in the light of the circumstances under which they were made, 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 information contained in the Registration Statement Questionnaire and the Questionnaire, which information or other written information furnished to the Company by the Purchaser expressly for use therein, and the Purchaser will 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; provided, however, that the obligations of the Purchaser under this Section 7.3 shall not exceed the net proceeds to such Purchaser from the sale of Shares pursuant to such Registration Statement.

(c) Promptly after receipt by an indemnified party under this Section 7.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7.3, promptly notify the indemnifying party in writing thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 7.3 (except to the extent that such omission materially and adversely affects the indemnifying person’s ability to defend such action). Subject to provisions hereinafter stated, 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 will 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 with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party, and the indemnifying party and the indemnified party, based upon the advice of such indemnified party’s counsel, shall have reasonably concluded that there may be a conflict of interest 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 and/or other indemnified parties which 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 and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by such indemnifying party in the case of paragraph (a), representing the indemnified parties who are parties to such action (including indemnified parties under Agreements with Other Purchasers, plus local counsel, if appropriate) or (ii) the indemnifying party shall not have employed 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. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could have been a

party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in this Section 7.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 7.3 in respect to any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying 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 herein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the placement of the Common Stock contemplated by this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchaser on the other shall be deemed to be in the same proportion as the amount paid by the Purchaser to the Company pursuant to this Agreement for the Shares purchased by the Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount the Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount received by the Purchaser from such sale. The relative fault of the Company on the one hand and the Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by the Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in paragraph (c) of this Section 7.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in paragraph (c) of this Section 7.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this paragraph (d); provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under paragraph (c) for purposes of indemnification. The Company and the Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 7.3 were determined solely by pro rata allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph. Notwithstanding the provisions of this Section 7.3, the Purchaser shall not be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchaser’s obligation to contribute pursuant to this Section 7.3 is several and not joint.

(e) The Purchaser hereby acknowledges that it is a sophisticated business person who was represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 7.3, and is fully informed regarding said provisions. Each of the Company and the Purchaser is advised that federal or state public policy as interpreted by the courts in certain jurisdictions may be contrary to certain of the provisions of this Section 7.3, and each of the Company and the Purchaser hereby expressly waives and relinquishes any right or ability to assert such public policy as a defense to a claim under this Section 7.3 and further agrees not to attempt to assert any such defense.

(f) The Company and the Purchaser agree that the Purchaser will suffer damages if the Registration Statement is not declared effective by the SEC on or prior to the Required Effective Date. The Company and the Purchaser further agree that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if the Registration Statement is not declared effective by the SEC on or prior to the Required Effective Date, the Company shall pay as liquidated damages for such failure and not as a penalty (the “Liquidated Damages”) to the Purchaser an amount equal to one percent (1%) of the total purchase price paid by such Purchaser pursuant to Section 1 hereof for each 30 day period after the Required Effective Date, pro rated for any period less than 30 days, following the Required Effective Date until the Registration Statement has been declared effective by the SEC. Payments to be made pursuant to this Section 7.3(f) shall be due and payable in cash to a Purchaser immediately upon demand of such Purchaser. Furthermore, after the effectiveness of the Registration Statement, if the Purchaser shall be unable or prohibited from selling Shares under the Registration Statement other than as a result of a Suspension of not more than thirty (30) days or Suspensions on not more than two (2) occasions of not more than thirty (30) days each in any 12-month period (a “Prohibited Period”), provided, during a Prohibited Period, Purchaser shall provide notice to the Company that it desires to sell Shares under the Registration Statement and is unable to sell such Shares under Rule 144, then the Company shall pay as Liquidated Damages to the Purchaser an amount equal to one percent (1%) of the total purchase price paid by such Purchaser pursuant to Section 1 hereof for each 30 day period in which such inability to sell is in effect or a Suspension is in effect that exceeds the maximum allowed period for a Suspension or Suspensions, but not including any day on which a Suspension is lifted, pro rated in each case for any period less than 30 days. For purposes of this Section 7.3, a Suspension shall be deemed lifted on the date that notice that the Suspension has been lifted is delivered to the Purchaser pursuant to Section 9 of this Agreement. Notwithstanding the foregoing provisions, in no event shall the Company be obligated to pay any Liquidated Damages to more than one Purchaser in respect of the same Shares for the same period of time. The parties agree that the Liquidated Damages represent a reasonable estimate on the part of the parties, as of the date of this Agreement, of the amount of damages that may be incurred by the Purchaser if the Registration Statement has not been declared effective by the SEC on or prior to the Required Effective Date, or if a Suspension exceeds the maximum allowed period.

7.4 Termination of Conditions and Obligations. The conditions precedent imposed by Section 5 or this Section 7 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares upon the earliest to occur of (i) the sale of the Shares pursuant to the Registration Statement, (ii) the sale of the Shares pursuant to Rule 144 under the Securities Act or (iii) the passage of two (2) years from the effective date of the Registration Statement covering such Shares or at such time as an opinion of counsel satisfactory

in form and substance to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act.

7.5 Information Available. As long as any Purchaser owns the Shares and the Company is subject to the filing requirements of the Exchange Act, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company relating to the Company after the date hereof pursuant to the Exchange Act. So long as the Registration Statement is effective covering the resale of Shares owned by the Purchaser, the Company will furnish to the Purchaser upon such Purchaser’s request:

(a) as soon as practicable after available (but in the case of the Company’s Annual Report to Stockholders, concurrently with delivery to its shareholders generally) one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements audited in accordance with United States generally accepted accounting principles by a national firm of certified public accountants), (ii) if not included in substance in the Annual Report to Stockholders, upon the request of the Purchaser, its Annual Report on Form 10-K, (iii) upon the request of the Purchaser, its Quarterly Reports on Form 10-Q, (iv) upon the request of the Purchaser, its Current Reports on Form 8-K, and (v) a full copy of the particular Registration Statement covering the Shares (the foregoing, in each case, excluding exhibits);

(b) all exhibits excluded by the parenthetical to subparagraph (a)(v) of this Section 7.5; and

(c) upon the reasonable request of the Purchaser, a reasonable number of copies of the prospectuses and supplements thereto to supply to any other party requiring such prospectuses and supplements; and the Company, upon the reasonable request of the Purchaser, will meet with the Purchaser or a representative thereof at the Company’s headquarters to discuss information relevant for disclosure in the Registration Statement covering the Shares; provided, that the Company shall disclose any confidential information to the Purchaser only if the Purchaser has requested such information in writing and shall have entered into a confidentiality agreement with the Company in form and substance reasonably satisfactory to the Company with respect thereto.

7.6 Assignment of Registration Rights. The rights of the Purchaser hereunder, including the right to have the Company register the Shares pursuant to this Agreement, will be deemed automatically assigned, upon the first transfer only, to permitted transferees or assignees of at least 50% of the Shares, but only if (a) the Purchaser agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (b) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the Shares with respect to which such registration rights are being transferred or assigned, (c) after such transfer or assignment, the further disposition of such Shares by the transferee or assignee is restricted under the Securities Act and applicable state securities laws, (d) at or before the time the Company received the written notice contemplated by clause (b) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein, (e) the transferee is an “accredited investor” as that term is

defined in Rule 501 of Regulation D, and (f) the transfer of Shares is made in accordance with the provisions of Section 5 and Section 7.2 hereof.

SECTION 8. Broker’s Fee. The Purchaser acknowledges that the Company intends to pay fees to the Placement Agent in respect of the sale of the Shares to the Purchaser. The Purchaser and the Company hereby agree that the Purchaser shall not be responsible for such fees. Each of the parties hereto hereby represents that, on the basis of any actions and agreements by it, there are no other brokers or finders entitled to compensation in connection with the sale of the Shares to the Purchaser.

SECTION 9. Notices. All notices, requests, consents and other communications hereunder shall be in writing, shall be sent by confirmed facsimile or nationally recognized overnight express courier postage prepaid, and shall be deemed given (i) when so faxed or (ii) the day after so mailed by such overnight express courier (except that notices of Suspensions or stop orders must be made by facsimile and overnight express courier) as follows:
