The Company shall, as expeditiously as possible, prepare and file with the Commission a Registration Statement with respect to the Registrable Securities and use its best efforts to cause the Registration Statement to become effective and to remain effective for the Applicable Period (as defined below) to enable the resale of the Registrable Securities in accordance with the method or methods of distribution reasonably requested by Purchasers and disclosed in the Registration Statement (the “Demand Registration”). The Company shall not include in any Demand Registration any securities which are not Registrable Securities without the written consent of the Holders of a majority of the Registrable Securities to be included in such registration; provided, however, that the Company may include in the Demand Registration (i) up to 300,000 shares of the Company’s common stock issued to HRI Consultants, a division of Homeowner’s Realty, Inc. (“HRI”) in connection with that certain Consulting Agreement (the “Consulting Agreement”), dated as of June 21, 2002, by and between the Company and HRI, and (ii) up to 37,500 shares of the company’s common stock issued or issuable in connection with the Common Stock Purchase Warrant, dated as of September 30, 2002, issued to HRI in connection with the Consulting Agreement, and (iii) up to 62,500 shares of the Company’s common stock issued or issuable in connection with the Common Stock Purchase Warrant, dated as of December 31, 2002, issued to HRI in connection with the Consulting Agreement. A registration shall not count as the Demand Registration (A) until the Registration Statement filed in connection with such Demand Registration has become effective, and (B) if each of the Holders is not able to register and offer for sale all of the Registrable Securities requested by such Holders to be included in such registration.

(b) Whenever the Company proposes to file a Registration Statement, prior to such filing it shall give written notice to each Holder of its intention to do so, and upon the written request of any Holder given within twenty (20) days after the Company provides such notice (which request shall state the intended method of disposition of such Underlying Shares), the Company shall cause all Registrable Securities which the Company has been requested to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the reasonable intended methods of distribution specified in the request of such Holder(s) (the “Piggyback Registration”). In connection with any Demand Registration or an offering under this Section 2(b), the Company shall not be required to include any Registrable

Securities in such underwriting unless the holders thereof accept the terms of the underwriting as agreed upon between the Company and the underwriters and then only in such quantity as will not, in the opinion of the underwriters, jeopardize the success of the offering by the Company. If in the opinion of the managing underwriter the registration of all, or part of, the Registrable Securities which the Holders have requested to be included would materially and adversely affect such public offering, then the Company shall be required to include in the underwriting subject to the priority provisions of Sections 2(c) or (d) as applicable, only that number of shares of Registrable Securities which the managing underwriter believes may be sold without causing such adverse effect. In the event of such a reduction in the number of shares to be included in the underwriting, the Holders of who have requested registration shall participate in the underwriting pro rata based upon their total ownership of Registrable Securities (or in any other proportion as agreed upon by such Holders) and if any of such Holders would thus be entitled to include more shares than such Holder requested to be registered, the excess shall be allocated among such other requesting Holders pro rata based on their ownership of Registrable Securities. No Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s Registrable Securities and such Holder’s intended method of distribution and any other representation required by law. If any of the Registrable Securities covered by a Demand Registration is to be sold in an underwritten offering, the holders of a majority of the Registrable Securities shall have the right to select the managing underwriter(s) to administer the offering subject to the approval of the Company, which will not be unreasonably withheld.

(c) Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering and/or that the number of shares of Registrable Securities proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities requested to be included therein by the Holders, pro rata among the Holders of such Registrable Securities on the basis of the number of shares requested to be registered by such Holders, and (iii) third, other securities requested to be included in such registration pro rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders or as such holders may otherwise agree.

(d) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of a holder of the Company’s securities other than Underlying Shares, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering and/or that the number of shares of Registrable Securities proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in such registration (i) first the securities requested to be included therein by the holders requesting such registration and the Registrable Securities requested to be included in such registration, pro rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders, and (ii) second, other securities requested to be included in such registration pro

rata among the holders of such securities on the basis of the number of shares requested to be registered by such holders or as such holders may otherwise agree.

(e) The Company shall not be obligated to register or to keep a Registration Statement effective with respect to any Registrable Securities: (i) if a Registration Statement with respect to the sale of such securities shall have become effective under the Securities Act and such securities shall have been disposed of in accordance with such Registration Statement or, if earlier, when the Applicable Period shall have expired with respect to such securities; (ii) if counsel to the Company reasonably determines they are eligible to be distributed to the public pursuant to Rule 144(k) (or any successor provision) under the Securities Act and, if requested by the Company’s transfer agent in connection with any sale by a Holder of the Registrable Securities, provides a legal opinion to the Company’s transfer agent to such effect; or (iii) when new certificates for the Registrable Securities not bearing a legend restricting further transfer shall have been delivered by the Company and subsequent disposition of them shall not require registration or qualification of them under the Securities Act or any similar state law then in force. If the Company shall withdraw any Registration Statement (a “Withdrawn Registration Statement”), the Holders of the Underlying Shares remaining unsold and originally covered by such Withdrawn Registration Statement shall be entitled to an additional Demand Registration which (subject to the provisions of this Section 2) the Company shall use its best efforts to keep effective for a period commencing on the effective date of such Registration Statement and ending on the earlier to occur of the date (i) which is one hundred eighty (180) days from the effective date of such Registration Statement and (ii) on which all of the Registrable Securities covered by such Demand Registration has been sold. Such additional Demand Registration otherwise shall be subject to all of the provisions of this Agreement.

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, defend, indemnify and hold harmless each Holder, the officers, directors, agents, investment advisors and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus covering the Registrable Securities or in any amendment or supplement thereto or in any preliminary prospectus covering the Registrable Securities, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that such untrue or alleged untrue statement or omissions or alleged omission are

based solely upon information regarding such Holder or such Holder’s proposed method of distribution of the Registrable Securities furnished to the Company by such Holder for use therein. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus covering the Registrable Securities or in any amendment or supplement thereto or in any preliminary prospectus covering the Registrable Securities, or arising out of or based upon any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading to the extent, but only to the extent, that such untrue statement or omission is contained in any written information so furnished by such Holder to the Company for the express inclusion in such Registration Statement or such Prospectus and that such information was reasonably relied upon by the Company for use in such Registration Statement, such Prospectus or such form of prospectus. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party promptly shall notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying 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 thereof and such counsel shall be at the expense of the Indemnifying Party); provided that if more than one Indemnified Party is seeking indemnification with respect to the same Proceeding, the Indemnifying Party shall not be required to pay for more than one separate counsel for all such Indemnified Parties as a group. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

(d) Contribution. If a claim for indemnification under Section 6(a) or 6(b) is unavailable to an Indemnified Party because of a failure or refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 6(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 6(d), the Purchaser shall not be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by the Purchaser from the sale of the Registrable Securities to the Proceeding exceeds the amount of any damages that the 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 indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

7. Miscellaneous

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by any party of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, each of the Company and each Holder shall waive the defense that a remedy at law would be adequate.
