(a) Restricted Shares shall not be sold or transferred unless either (i) they first shall have been registered under the Securities Act, or (ii) the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Securities Act. (b) Notwithstanding the foregoing, no registration or opinion of counsel shall be required for (i) a transfer by a Purchaser which is a corporation to a wholly owned subsidiary of such corporation, a transfer by a Purchaser which is a partnership to a partner of such partnership or a retired partner of such partnership who retires after the date hereof, or to the estate of any such partner or retired partner, or a transfer by a Purchaser which is a limited liability company to a member of such limited liability company or a retired member who resigns after the date hereof or to the estate of any such member or retired member; provided that the transferee in each case agrees in writing to be subject to the terms of this Section 8 to the same extent as if it were the original Purchaser hereunder, or (ii) a transfer made in accordance with Rule 144 under the Securities Act. 8.3 Legend. Each certificate representing Restricted Shares shall bear a legend substantially in the following form: "The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such shares are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required." The foregoing legend shall be removed from the certificates representing any Restricted Shares, at the request of the holder thereof, at such time as they become eligible for resale pursuant to Rule 144(k) under the Securities Act. 9. Indemnification. 19 9.1 Indemnification by the Company. Notwithstanding anything in this Agreement to the contrary, but subject to the other provisions of this Section 9, the Company shall indemnify, defend, and hold the Purchasers, the Purchasers' directors, partners, officers and affiliates, and each of such partners' and Affiliates' officers, directors, partners, employees, representatives and affiliates, (collectively, the "Purchaser Indemnitees") harmless from and against, and shall reimburse them for, any and all demands, claims, losses, liabilities, damages, costs, and expenses whatsoever (including, without limitation, any fines, penalties, reasonable fees and disbursements of counsel incurred by the Purchaser Indemnitees in investigating or defending any of the foregoing, and other reasonable expenses incurred investigating or defending any of the foregoing or enforcing this Agreement) sustained or incurred by a Purchaser Indemnitee resulting from or arising in connection with any inaccuracy in or breach of any of the representations or warranties of the Company set forth in this Agreement or the Schedules or Exhibits hereto; provided, however, that the total liability of the Company under this Section 9 shall not exceed the aggregate Purchase Price paid by the Purchaser Indemnitees pursuant to this Agreement. 9.2 Indemnification by the Purchasers. Notwithstanding anything in this Agreement to the contrary, but subject to the other provisions of this Section 9, each of the Purchasers shall severally and not jointly indemnify, defend, and hold the Company, the Company's directors, partners, officers and affiliates, and each of such partners' and Affiliates' officers, directors, partners, employees, representatives and affiliates, (collectively, the "Company Indemnitees") harmless from and against, and shall reimburse them for, any and all demands, claims, losses, liabilities, damages, costs, and expenses whatsoever (including, without limitation, any fines, penalties, reasonable fees and disbursements of counsel incurred by the Company Indemnitees in investigating or defending any of the foregoing, and other reasonable expenses incurred investigating or defending any of the foregoing or enforcing this Agreement) sustained or incurred by a Company Indemnitee resulting from or arising in connection with any inaccuracy in or breach of any of the representations or warranties of such Purchaser set forth in this Agreement or the Schedules or Exhibits hereto; provided, however, that the total liability of such Purchaser under this Section 9 shall not exceed the aggregate Purchase Price paid by such Purchaser pursuant to this Agreement. 9.3 Indemnification Notice. In the event that (i) an event occurs which gives a person or entity a right to indemnification hereunder or (ii) any third party claim is asserted against a person or entity with respect to which such person or entity is entitled to indemnification hereunder, such person or entity (the "Indemnified Party") shall, within 60 days of the later of the occurrence of the event giving rise to the claim or the date that the indemnified party learned of such claim (provided, however, that if a claim arises by virtue of litigation, then in no event less than 10 days prior to the date in which an appearance or answer is due, whichever is earlier), notify the person or entity obligated to indemnify it (the "Indemnifying Party") of such claim by delivery of a written notice describing the claim and indicating the basis for indemnification hereunder. The Indemnifying Party will have the right, upon written notice to the Indemnified Party within 10 days after receipt from the Indemnified Party of notice of such claim, to conduct at its expense the defense against such claim in its own name, or if necessary in the name of the Indemnified Party. In the event that the Indemnifying Party fails to give such notice, it will be deemed to have elected not to conduct the defense of the subject claim, and in such event the Indemnified Party will have the right to conduct such defense and, only with the prior consent of the Indemnifying Party which will not be unreasonably withheld, to compromise and settle the claim. In the event that the Indemnifying Party does elect to conduct the defense of the subject claim, the Indemnified Party shall cooperate with and make available to the Indemnifying Party such assistance and materials as may be reasonably requested by it, all at the expense of the Indemnifying Party and the Indemnified Party will have the right at its expense to participate in the defense, provided that the Indemnified Party will have the right to compromise and settle the claim only with the prior written consent of the Indemnifying Party. Any settlement to which the Indemnifying Party has consented in writing will conclusively be deemed to be an obligation with respect to which the Indemnified Party is entitled to indemnification hereunder. 10. Termination and Default. The obligations of the Purchasers and the Company with respect to consummating the Second Closing shall terminate in upon the occurrence of any of the following events: 10.1 Mutual Consent. The obligations of the parties hereto to consummate the Second Closing may be terminated by the mutual written consent of the parties. 10.2 Order or Decree. The obligations of the parties hereto to consummate the Second Closing may be terminated by any Purchaser or the Company if any Governmental Authority shall have issued an order, decree, ruling or taken any other action restraining, enjoining or otherwise prohibiting in any material respects the transactions contemplated hereby and such order, decree, ruling or other action shall have become final and nonappealable. 10.3 Outside Date. The obligations of the parties hereto to consummate the Second Closing may be terminated by either party if (a) the Second Closing shall not have occurred by December 31, 2000 (the "Outside Date"), or (b) if one or more conditions to the other party's obligation to consummate the transactions contemplated hereby cannot be satisfied by the Outside Date; provided, however, that no party may exercise its rights under this Section 10 if such party is in material breach or default under this Agreement. 20 10.4 Procedure Upon Termination. In the event of the termination of the obligations of the parties hereto to consummate the Second Closing, written notice thereof shall promptly be given to the other parties hereto and the obligations of the parties hereto to consummate the Second Closing shall terminate, all further obligations of the parties hereunder to satisfy the conditions precedent to the Second Closing shall terminate, and the transactions relating to the Second Closing shall be abandoned without further action by any of the parties hereto. 10.5 Effect of Termination. Nothing in this Article X shall relieve any party hereto of any liability for intentional or willful breach of this Agreement, including willful failure to fulfill a condition or to perform a covenant. The parties shall have no liability as a result of the failure of the Second Closing to occur for any reason other than an intentional or willful breach of this Agreement. 11. Miscellaneous. 11.1 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. This Agreement, and the rights and obligations of each Purchaser hereunder, may be assigned by such Purchaser to any person or entity to which at least 1,000,000 Shares are transferred by such Purchaser, and such transferee shall be deemed a "Purchaser" for purposes of this Agreement; provided that the transferee provides written notice of such assignment to the Company. The Company may not assign its rights under this Agreement. 11.2 Confidentiality. Each Purchaser agrees that he, she or it will keep confidential and will not disclose, divulge or use for any purpose other than to monitor his, her or its investment in the Company any confidential, proprietary or secret information which such Purchaser may obtain from the Company pursuant to financial statements, reports and other materials submitted by the Company to such Purchaser pursuant to this Agreement, or pursuant to visitation or inspection rights granted hereunder ("Confidential Information"), unless such Confidential Information is known, or until such Confidential Information becomes known, to the public (other than as a result of a breach of this Section 11.2 by such Purchaser); provided, however, that a Purchaser may disclose Confidential Information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company and to the extent that such individuals agree to be bound by the provisions of this Section 11.2, (ii) to any prospective purchaser of any Shares from such Purchaser as long as such prospective purchaser agrees to be bound by the provisions of this Section 11.2, (iii) to any affiliate of such Purchaser or to a partner, stockholder or subsidiary of such Purchaser, provided that such affiliate agrees in writing to be bound by the provisions of 21 this Section 11.2, or (iv) as may otherwise be required by law, provided that the Purchaser takes reasonable steps to minimize the extent of any such required disclosure. 11.3 Survival of Representations and Warranties.

The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. 11.7 Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement, each Purchaser shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such other injunctive or other equitable relief as may be granted by a court of competent jurisdiction. 11.8 Governing Law.

Notwithstanding the foregoing, this Agreement may be amended or terminated, and any right hereunder may be waived with respect to all parties to this Agreement, with the consent of the Company and the holders of less than all of the shares of Common Stock issued or issuable upon conversion of the Shares only in a manner which applies to all such holders in the same fashion. Any amendment, termination or waiver effected in accordance with this Section 11.11 shall be binding upon each holder of any Shares (including shares of Common Stock into which such Shares have been converted), even if they do not execute such consent, each future holder of all such securities and the Company. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision. 23 11.12 Pronouns.
