(vi) prior to any public offering of Transfer Restricted Securities, cooperate with the selling Holders and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions as the selling Holders may reasonably request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Resale Registration Statement; provided that the Company shall not be required to register or qualify as a foreign corporation where it is not now so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Resale Registration Statement, in any jurisdiction where it is not now so subject; (vii) cooperate with the selling Holders to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and registered in such names as the Holders may reasonably request at least two (2) business days prior to any sale of Transfer Restricted Securities made by such selling Holders; (viii) use its reasonable best efforts to cause the Transfer Restricted Securities covered by the Resale Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Transfer Restricted Securities, subject to the provisions contained in Section 4(b)(vi) above; (ix) if any fact or event contemplated by Section (b)(iii)(D) above shall exist or have occurred, prepare as soon as practicable a supplement or post-effective amendment to the Resale Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; (x) cooperate and assist in any filings required to be made with the NASD and use its reasonable best efforts to cause such filings to become effective and approved by such governmental agencies or authorities as may be necessary to enable the Holders selling Transfer Restricted Securities to consummate the disposition of such Transfer Restricted Securities; (xi) otherwise comply with all applicable rules and regulations of the Commission; (xii) cause all shares of Transfer Restricted Securities covered by the Resale Registration Statement to be listed on each securities exchange or market, if applicable, on which similar securities issued by the Company are then listed; and (xiii) provide promptly to each Holder upon request each document filed with the Commission pursuant to the requirements of Section 13 or Section 15 of the Exchange Act. (c) BLACKOUT.Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 4(b)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the Resale Registration Statement until such Holder's receipt of the copies of the supplemented or amended Prospectus as contemplated by section 4(b)(xiii) hereof, or until it is advised in writing (the "Advice") by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. The Company shall use its best efforts to take such actions as are necessary to provide such Advice within thirty (30) days of the date of any notice from the Company of the existence of any fact of the kind described in Section 4(b)(iii)(D) hereof. If so directed by the Company, each Holder will deliver to the Company all copies, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Transfer Restricted Securities that was current immediately prior to the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of such Resale Registration Statement set forth in Section 3(b)(ii) shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 4(b)(iii)(D) hereof to and including the date when each selling Holder covered by such Resale Registration Statement shall have received the copies of the supplemented or amended Prospectus as contemplated by section 4(b)(ix) hereof or shall have received the Advice. SECTION 5.

Each Holder shall pay all expenses of its counsel and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder's Transfer Restricted Securities pursuant to the Resale Registration Statement. SECTION 6. INDEMNIFICATION (a) The Company shall indemnify and hold harmless (i) each Holder and (ii) the respective representatives and agents of any Holder (any person referred to in clause (i) or (ii) may hereinafter be referred to as an "Indemnified Holder"), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, judgments, actions and expenses, joint or several (including without limitation, reimbursement of all reasonable costs of investigating, preparing, pursuing or defending any claim or action, investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and charges of counsel) directly or indirectly caused by, related to, based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained in (A) the Resale Registration Statement or Prospectus (or any amendment or supplement thereto) or (B) any state securities or Blue Sky application or other document prepared or executed by the Company (or based upon any information furnished by the Company) for the purpose of qualifying any of the Securities under the securities or Blue Sky laws of any state or other jurisdiction (any such application, document or information hereinafter is referred to as a "Blue Sky Application") or any omission or alleged omission to state in the Resale Registration Statement or Prospectus (or any amendment or supplement thereto) or in any Blue Sky Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, except insofar as such losses, claims, damages, liabilities or expenses are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Company by any of the Holders or counsel or agents of Holders expressly for use therein. The foregoing indemnification is in addition to any liability which the Company may otherwise have to any Indemnified Holder. (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, and its respective directors, officers, employers or agents and any person controlling (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Company, and to the same extent as the foregoing indemnity from the Company to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to such Holder furnished in writing by such Holder expressly for use in the Resale Registration Statement or Prospectus. The foregoing indemnification is in addition to any liability which any Holder may otherwise have to the Company or any Controlling Person. No Holder shall be required to indemnify the Company in an amount greater than the product of $7.50 multiplied by the number of shares set forth by such Holder's name in Schedule 1 hereto. (c) Promptly after receipt by an indemnified party under this Section 6 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6 (except to the extent so provided in any such other obligation). If any such claim or action shall be brought against an indemnified party, and it shall have notified the indemnifying thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation, provided, however, that the indemnified party shall have the right to employ separate counsel to represent jointly the indemnified party and those other Indemnified Holders and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by Indemnified Holders against the indemnifying party under this Section 6, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized by the indemnifying party in writing, (ii) such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to local counsel). Each indemnified party, as a condition of the indemnity agreements contained in this Section 6, shall use its reasonable best efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall (i) without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding or (ii) be liable for any settlement of any such action, compromise of any action or any judgment with respect to any action the entry of which was consented to, effected without its written consent, but if settled with its written consent or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party, to the extent set forth herein, from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 6 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative fault of the Company on the one hand and the Holders on the other hand with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to whether the untrue or alleged statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Holders, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Holders agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were to be determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 6(d) shall be deemed to include, for purposes of this Section 6(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no Indemnified Holder shall be required to contribute any amount in excess of the amount by which proceeds received by such Indemnified Holder from an offering of the Securities exceeds the amount of any damages which such Indemnified Holder has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Indemnified Holders' obligations to contribute as provided in this Section 6(d) are several and not joint. SECTION 7. RULE 144 AND RULE 144A The Company hereby agrees with each Holder, for so long as such Holder owns any Transfer Restricted Securities, to make available to such Holder the information required by Rule 144 under the Act in order to permit resales of such Transfer Restricted Securities by such Holder pursuant to Rule 144. The Company hereby agrees with each Holder, for so long as such Holder owns any Transfer Restricted Securities, to make available to such Holder the information required by Rule 144A(d)(4) under the Act in order to permit resales of such Transfer Restricted Securities by such Holder pursuant to Rule 144A. SECTION 8. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS No Holder may sell any Transfer Restricted Security in an Underwritten Registration pursuant to this Agreement; provided, however, if at any time prior -------- ------- to the filing of the Resale Registration Statement the Board of Directors of the Company shall determine to file with the SEC a registration statement relating to an offering for its own account or the account of others under the Act of any of its equity securities (other than on Form S-4 or Form S-8 or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans) (collectively, a "Piggyback Registration Statement"), the Company shall send to each Holder ---------------------------------- written notice of such determination and, if within ten (10) days after the effective date of such notice, such Holder shall so request in writing, the Company shall include in such Piggyback Registration Statement the Transfer Restricted Securities of such Holder eligible to be included in a Resale Registration Statement, except that if, in connection with any Underwritten Offering for the account of the Company the managing underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the Piggyback Registration Statement because, in such underwriter(s) judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such Piggyback Registration Statement only such limited portion of the Transfer Restricted Securities with respect to which such Holder has requested inclusion hereunder as the underwriter shall permit. Any exclusion of Transfer Restricted Securities shall be made pro rata among the Holders seeking to include Transfer Restricted Securities in proportion to the number of Transfer Restricted Securities sought to be included by such Holders. SECTION 9. MISCELLANEOUS (a) REMEDIES. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. (b) NO INCONSISTENT AGREEMENTS.The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way breach or conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof. (c) AMENDMENTS AND WAIVERS.The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has obtained the written consent of Holders of ninety percent (90%) of the then outstanding Transfer Restricted Securities. Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose Transfer Restricted Securities are being resold pursuant to the Resale Registration Statement and that does not affect directly or indirectly the rights of other Holders whose Transfer Restricted Securities are not being resold pursuant to such Resale Registration Statement may be given by the Holders of a majority of the outstanding Transfer Restricted Securities being resold pursuant to such Resale Registration Statement.
