(b) NUMBER OF DEMAND REGISTRATIONS. The Company shall be obligated to effect not more than three (3) Demand Registrations. (c) PRIORITY ON DEMAND REGISTRATION. If any of the Registrable Securities registered pursuant to Demand Registrations are to be sold in one or more firm commitment underwritten offerings, and the managing underwriter or underwriters advise the Company and the Investor in writing that in their opinion the total number or dollar amount of Registrable Securities requested to be included in such registration is sufficiently large to adversely affect the success of such offering, the Company shall include, on behalf of the Investor, in such firm commitment underwritten offering the number of shares of Registrable Securities which, in the opinion of such managing underwriter or underwriters, can be sold without any adverse affect on the offering.

If any Demand Registration is in the form of an underwritten offering, the Company will select and obtain the investment banker or investment bankers and manager or managers that will administer the offering. 4. PIGGYBACK REGISTRATIONS (a) RIGHT TO PIGGYBACK. Whenever the Company proposes (whether or not for its own account) to register any of its equity securities under the Securities Act except with respect to a registration statement (i) on Form S-8 or any successor form to such Form or (ii) filed in connection with an exchange offer or relating to a transaction pursuant to Rule 145 of the Securities Act, the Company shall give written notice to the Investor of its intention to effect such a registration not later than thirty (30) days prior to the anticipated date of filing with the SEC of a Registration Statement with respect to such registration. Such notice shall offer the Investor the opportunity to include in such Registration Statement such Registrable Securities as the Investor may request (a "Piggyback Registration"). Subject to the provisions of Sections 4(b) and 4(c) hereof, the Company shall include in each such Piggyback Registration all Registrable Securities with respect to which the Company has received a written request for inclusion therein within fifteen (15) days after the receipt by the Investor of the Company's notice. No registration effected pursuant to a request or requests referred to in this Section 4 shall be deemed Demand Registrations pursuant to Section 3. Upon the giving of notice of a proposed registration by the Company pursuant to this Section 4(a), the Investor may exercise only its rights to Piggyback Registration and not Demand Registration as to the Company's proposed registration. (b) PRIORITY ON PRIMARY REGISTRATION. If a Piggyback Registration is being made with respect to an underwritten primary registration on behalf of the Company and the managing underwriter or underwriters advise the Company in writing that in their opinion the total number or dollar amount of securities of any class requested to be included in such registration is sufficiently large to adversely affect the success of such offering, the Company shall include in such registration: (1) first, all securities the Company proposes to sell to the public, the proceeds of which shall go to the Company, (2) second, up to the full number of Registrable Securities requested to be included in such registration in excess of the number or dollar amount of securities the Company proposes to sell which, in the opinion of such managing underwriter or underwriters, can be sold without adversely affecting the offering. (c) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is being made with respect to an underwritten secondary registration on behalf of holders of the securities of the Company, and the managing underwriters advise the Company in writing that in their opinion the dollar amount or number of securities of any class requested to be included in such registration is sufficiently large to adversely affect the success of such offering, the Company shall include in such registration (1) first, up to the full number of securities requested to be included therein by holders exercising demand registration rights which in the opinion of such underwriter can be sold without adversely affecting the offering and (2) second, up to the full number of Registrable Securities requested to be included in such registration in excess of the number or dollar amount of securities which holders exercising demand registration rights propose to sell, which, in the opinion of such managing underwriter or underwriters, can be sold without adversely affecting the offering. 5. HOLD-BACK AGREEMENTS (a) RESTRICTIONS ON PUBLIC SALE BY THE INVESTOR. The Investor agrees, if requested by the managing underwriter or underwriters in any underwritten offering (to the extent timely notified in writing by the Company or the managing underwriter or underwriters) of the Company's securities covered by a Registration Statement, not to effect any public sale or distribution of any Registrable Securities not included in such Registration Statement, including a sale pursuant to Rule 144 under the Securities Act (except as part of such underwritten registration), during the ten (10) day period prior to, and during the forty-five (45) day period beginning on, the effective date of each underwritten offering made pursuant to such Registration Statement, provided that Investor shall not be obligated to delay the public sale or distribution of Registrable Securities for a period in excess of one hundred ten (110) days in any twelve-month period. Such forty-five (45) day period shall be extended with regard to the Registrable Securities to such longer period as may be agreed to in writing by the Investor. The foregoing provisions shall not apply to the Investor if it is prevented by applicable statute or regulation from entering into any such agreement; PROVIDED that the Investor shall undertake, in its request to participate in any such underwritten offering, not to effect any public sale or distribution of the applicable Registrable Securities commencing on the date of sale of such applicable class of Registrable Securities pursuant to such a Registration Statement unless it has provided forty-five (45) days prior written notice of such sale or distribution to the managing underwriter or underwriters.

(h) DISPUTE RESOLUTION. No party to this agreement shall be entitled to take legal action with respect to any dispute relating hereto until it has complied in good faith with the following alternative dispute resolution procedures. This section shall not apply to the extent it is deemed necessary to take legal action immediately to preserve a party's adequate remedy. (i) NEGOTIATION. The parties shall attempt promptly and in good faith to resolve any dispute arising out of or relating to this Contract, through negotiations between representatives who have authority to settle the controversy. Any party may give the other party(ies) written notice of any such dispute not resolved in the normal course of business. Within 20 days after delivery of the notice, representatives of both parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to exchange information and to attempt to resolve the dispute, until the parties conclude that the dispute cannot be resolved through unassisted negotiation. Negotiations extending sixty days after notice shall be deemed at an impasse, unless otherwise agreed by the parties. If a negotiator intends to be accompanied at a meeting by an attorney, the other negotiator(s) shall be given at least three working days' notice of such intention and may also be accompanied by an attorney. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal and state Rules of Evidence. (ii) ADR PROCEDURE. If a dispute with more than $20,000.00 at issue has not been resolved within 60 days of the disputing party's notice, a party wishing resolution of the dispute ("Claimant") shall initiate assisted Alternative Dispute Resolution ("ADR") proceedings as described in this Section. Once the Claimant has notified the other party ("Respondent") of a desire to initiate ADR proceedings, the proceedings shall be governed as follows: By mutual agreement, the parties shall select the ADR method they wish to use. That ADR method may include arbitration, mediation, mini-trial, or any other method which best suits the circumstances of the dispute. The parties shall agree in writing to the chosen ADR method and the procedural rules to be followed within 30 days after receipt of notice of intent to initiate ADR proceedings. To the extent the parties are unable to agree on procedural rules in whole or in part, the current Center for Public Resources ("CPR") Model Procedure for Mediation of Business Disputes, CPR Model Mini-trial Procedure, or CPR Commercial Arbitration Rules--whichever applies to the chosen ADR method--shall control, to the extent such rules are consistent with the provisions of this Section. If the parties are unable to agree on an ADR method, the method shall be arbitration. The parties shall select a single Neutral (as defined by CPR) third party to preside over the ADR proceedings, by the following procedure: Within 15 days after an ADR method is established, the Claimant shall submit a list of 5 acceptable Neutrals to the Respondent. Each Neutral listed shall be sufficiently qualified, including demonstrated neutrality, experience and competence regarding the subject matter of the dispute. A Neutral shall be deemed to have adequate experience if an attorney or former judge. None of the Neutrals may be present or former employees, attorneys, or agents of either party. The list shall supply information about each Neutral, including address, and relevant background and experience (including education, employment history and prior ADR assignments). Within 15 days after receiving the Claimant's list of Neutrals, the Respondent shall select one Neutral from the list, if at least one individual on the list is acceptable to the Respondent. If none on the list are acceptable to the Respondent, the Respondent shall submit a list of 5 Neutrals, together with the above background information, to the Claimant. Each of the Neutrals shall meet the conditions stated above regarding the Claimant's Neutrals. Within 15 days after receiving the Respondent's list of Neutrals, the Claimant shall select one Neutral, if at least one individual on the list is acceptable to the Respondent. If none on the list are acceptable to the Claimant, then the parties shall request assistance from CPR to select a Neutral. The ADR proceeding shall take place within 30 days after the Neutral has been selected. The Neutral shall issue a written decision within 30 days after the ADR proceeding is complete. Each party shall be responsible for an equal share of the costs of the ADR proceeding. The parties agree that any applicable statute of limitations shall be tolled during the pendency of the ADR proceedings, and no legal action may be brought in connection with this agreement during the pendency of an ADR proceeding. The Neutral's written decision shall become final and binding on the parties, unless a party objects in writing within 30 days of receipt of the decision.
