similar event, that, in the judgment of Company’s Board of Directors, renders it advisable to suspend use of the prospectus, may, for no more than thirty (30) days in the aggregate, suspend use of the prospectus, on written notice to each Purchaser (which notice will not disclose the content of any material non-public information and will indicate the date of the beginning and end of the intended period of suspension, if known), in which case each Purchaser shall discontinue disposition of Registrable Shares covered by the Registration Statement or prospectus until copies of a supplemented or amended prospectus are distributed to the Purchasers or until the Purchasers are advised in writing by the Company that sales of Registrable Shares under the applicable prospectus may be resumed and have received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such prospectus. The suspension and notice thereof described in this Section 5(c)(ii) shall be held in strictest confidence and shall not be disclosed by the Purchasers. The Company may not utilize the suspension described in this Section 5(c)(ii) more than two (2) times in the aggregate.

(iii) Subject to paragraph (iv) below, in the event of: (1) 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, (2) 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, (3) the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Shares for sale in any jurisdiction or the initiation of any proceeding for such purpose, or (4) any event or circumstance which 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 any omission 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 any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, then the Company shall deliver a certificate in writing to the Purchasers (the “Suspension Notice”) to the effect of the foregoing (which notice will not disclose the content of any material non-public information and will indicate the date of the beginning and end of the intended period of suspension, if known), and, upon receipt of such Suspension Notice, the Purchasers will discontinue disposition of Registrable Shares covered by to the Registration Statement or prospectus (a “Suspension”) until the Purchasers’ receipt of copies of a supplemented or amended prospectus prepared and filed by the Company, or until the Purchasers are advised in writing by the Company that the current prospectus may be used, and have received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such prospectus. In the event of any Suspension, the Company will use its commercially reasonable efforts to cause the use of the prospectus so suspended to be resumed as soon as possible after delivery of a Suspension Notice to the Purchasers. The Suspension and Suspension Notice described in this Section 5(c)(iii) shall be held in strictest confidence and shall not be disclosed by the Purchasers.

(iv) Provided that a Suspension is not then in effect, the Purchasers may sell Registrable Shares under the Registration Statement, provided that the selling Purchaser arranges for

-13-

delivery of a current prospectus to the transferee of such Registrable Shares to the extent such delivery is required by applicable law.

(v) In the event of a sale of Registrable Shares by a Purchaser, such Purchaser must also deliver to the Company’s transfer agent, with a copy to the Company, a certificate of subsequent sale reasonably satisfactory to the Company, so that ownership of the Registrable Shares may be properly transferred. The Company will cooperate to facilitate the timely preparation and delivery of certificates (unless otherwise required by applicable law) representing Registrable Shares sold.

(d) Indemnification. For the purpose of this Section 5(d), the term “Registration Statement” shall include any preliminary or final prospectus, exhibit, supplement or amendment included in or relating to the Registration Statement referred to in Section 5(a).

(i) Indemnification by the Company. The Company agrees to indemnify and hold harmless each of the Purchasers and each person, if any, who controls any Purchaser within the meaning of the Securities Act, to the fullest extent permitted by law, against any and all losses, claims, damages, liabilities or expenses, joint or several, to which such Purchasers or such 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 Company, which consent shall not be unreasonably withheld), 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, 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 any of them, in light of the circumstances under which they were made, not misleading, and will reimburse each Purchaser and each such controlling person for any legal and other expenses as such expenses are reasonably incurred by such Purchaser or such controlling person 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 that any such loss, claim, damage, liability, expense or action arises out of or is based upon (1) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment to or supplement of the Registration Statement or Prospectus made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use in the Registration Statement or the Prospectus, (2) the failure of such Purchaser to comply with the covenants and agreements contained in this Agreement respecting resale of the Purchased Shares, or (3) any untrue statement or omission of a material fact required to make such statement not misleading in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser before the pertinent sale or sales by the Purchaser.

(ii) Indemnification by the Purchaser. Each Purchaser will severally and 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 the Securities Act, against any losses, claims, damages, liabilities or expenses to which

-14-

the Company, its directors, its officers who signed the Registration Statement and any controlling persons 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 such Purchaser, which consent shall not be unreasonably withheld) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (1) any failure on the part of such Purchaser to comply with the covenants and agreements contained in this Agreement respecting the sale of the Purchased Shares or (2) 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 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 therein 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 such 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, and any controlling persons for any legal and other expense reasonably incurred by the Company, its directors, its officers who signed the Registration Statement, and any controlling persons, in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Purchaser shall not be liable for any such untrue or alleged untrue statement or omission or alleged omission with respect to which the Purchaser has delivered to the Company in writing a correction before the occurrence of the event from which such loss was incurred. Notwithstanding the provisions of this Section 5(d), the Purchaser shall not be liable for any indemnification obligation under this Agreement in excess of the aggregate amount of net proceeds received by the Purchaser from the sale of the Registrable Shares pursuant to the Registration Statement.

(iii) Indemnification Procedure.

(1) Promptly after receipt by an indemnified party under this Section 5(d) 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 5(d), promptly notify the indemnifying party in writing of the claim; 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 under the indemnity agreement contained in this Section 5(d) or otherwise, to the extent it is not prejudiced as a result of such failure.

(2) 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 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

-15-

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 and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 5(d) for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless:

a) 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, representing all of the indemnified parties who are parties to such action); or

b) 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 the action against the indemnified party,

in each of which cases the reasonable fees and expenses of counsel for the indemnified party shall be at the expense of the indemnifying party.

(iv) Contribution. If the indemnification provided for in this Section 5(d) is required by its terms but is for any reason held to be unavailable to, or is otherwise insufficient to hold harmless, an indemnified party under this Section 5(d) with respect to any losses, claims, damages, liabilities or expenses referred to in this Agreement, then each 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 in this Agreement:

(1) in such proportion as is appropriate to reflect the relative faults 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, or

(2) if the allocation provided by clause (1) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative faults referred to in clause (1) above but the relative benefits received by the Company and the Purchaser from the placement of Common Stock.

The respective relative benefits received by the Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount to which the consideration paid by such Purchaser to the Company pursuant to this Agreement for the Purchased Shares purchased by such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount such Purchaser paid for the Purchased Shares that were sold pursuant to the Registration Statement and the amount received by such Purchaser from such sale. The relative fault of the Company and each Purchaser shall be determined by

-16-

reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate material fact relates to information supplied by the Company or by such Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such 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 Section 5(d)(iii), 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 Section 5(d)(iii) 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 Section 5(d)(iv); provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under Section 5(d)(iii) for purposes of indemnification. The Company and each Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 5(d)(iv) were determined solely by pro rata allocation (even if the Purchasers 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 5(d)(iv), no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that 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 is not guilty of such fraudulent misrepresentation. The Purchasers’ obligations to contribute pursuant to this Section 5(d)(iv) are several and not joint.

(e) Rule 144 Information. For two years after the date of this Agreement, the Company shall file in a timely manner all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated thereunder and shall take such further action to the extent required to enable the Purchasers to sell the Purchased Shares pursuant to Rule 144 under the Securities Act (as such rule may be amended from time to time).

6. ADVISORY FEE. The Purchasers acknowledge that the Company intends to pay to ▇.▇. ▇▇▇▇▇▇▇▇▇, Towbin, a financial advisor, a fee in respect of the sale of the Purchased Shares. Each of the parties to this Agreement 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 Purchased Shares to the Purchasers. The Company shall indemnify and hold harmless the Purchasers from and against all fees, commissions or other payments owing by the Company to ▇.▇. ▇▇▇▇▇▇▇▇▇, Towbin or any other person or firm acting on behalf of the Company hereunder.
