Subject to the provisions of SECTION 3(B), at any time after the first anniversary of the Closing, (A) one or more holders of Shares or Common Stock representing a Majority of the Registrable Securities may demand that the Company register all or part of its Registrable Securities under the Securities Act (a "DEMAND REGISTRATION") on Form S-1 (or a similar form then in effect) promulgated by the SEC under the Securities Act, provided that the Company shall not be obligated to effect a Demand Registration (i) during the one hundred eighty (180) days period commencing with the date of any secondary public offering or (ii) if the Company delivers notice to the holders of Registrable Securities within thirty (30) days of any registration request of its intent to file a registration statement for a secondary public offering within sixty (60) days and (B) one or more holders Shares or Common Stock representing a Majority of the Registrable Securities may request a Demand Registration on Form S-3 (or a similar form then in effect), provided that the Registrable Securities to be covered by any such Form S-3 shall be expected to result in aggregate gross proceeds of not less than $1,000,000. Within ten (10) days after receipt of a demand, the Company will notify in writing all holders of Registrable Securities of the demand. Any holder who wants to include its Registrable Securities in the Demand Registration must notify the Company within ten (10) business days of receiving the notice of the Demand Registration. Except as provided in this SECTION 3, the Company will include in all Demand Registrations all Registrable Securities for which the Company receives the timely written requests for inclusion. Any such request to be included in a Demand Registration shall not be counted as a Demand Registration under this SECTION 3. All demands or requests made pursuant to this SECTION 3(A) must specify the number of Registrable Securities to be registered and the intended method of disposing of the Registrable Securities. The Company acknowledges that the plan of distribution contemplated by any such Registration Statement shall include offers and sales through underwriters or agents, offers and sales directly to investors, block trades and such other methods of offer and sale and 4 that offers and sales may be on a continued or delayed basis under Rule 415. The Company will cause such Registration Statement to remain effective until such time as all of the shares of Common Stock designated thereunder are sold or the holders thereof are entitled to rely on Rule 144(k) for sales of Registrable Securities without registration under the Securities Act and without compliance with the public information, sales volume, manner of sale or notice requirements of Rule 144(c), (e), (f) or (h). The Company acknowledges that at the time the Company files any Registration Statement pursuant to this SECTION 3 the number of Registrable Securities may not be fixed due to the antidilution and other provisions related to the Shares ("Adjustment Provisions") and due to possible future issuances of Shares as dividends on the Shares ("Subsequent Shares"). Accordingly, the Company agrees that it will register the number of shares of Common Stock issuable upon conversion of Shares held by or issuable to the Investor as of the date of the filing of the Registration Statement and, to the extent permitted under the applicable rules under the Securities Act, the additional number of shares of Common Stock issuable pursuant to the Adjustment Provisions. The Company agrees that, thereafter, it will file, as soon as practicable but in no event later than thirty (30) days after the issuance of additional Registrable Securities that are not covered by such Registration Statement (due to the effect of the Adjustment Provisions and the Subsequent Shares) such amendments and/or supplements to the Registration Statement, and such additional Registration Statements as are necessary in order to ensure that at least 100% of the number of shares of Common Stock issuable on conversion of the Shares held by or issuable to the Investor are included in a Registration Statement, and the Company will use its reasonable best efforts to cause such amendments, supplements and additional Registration Statements to be declared effective within ninety (90) days following the issuance of such additional Registrable Securities that are not otherwise covered by an effective Registration Statement. (b) NUMBER OF DEMANDS. The holders of Registrable Securities shall have the right to three (3) Demand Registrations on Form S-1 (or a similar form then in effect) and shall have the right to an unlimited number of Demand Registrations on Form S-3 (or a similar form then in effect); PROVIDED, that the Company shall not be obligated to effect more than two (2) Demand Registrations on Form S-3 in any twelve (12) month period. (c) REGISTRATION EXPENSES. The Company shall pay or reimburse to the holders of the Registrable Securities included in a Demand Registration all Registration Expenses of those holders in connection with any Demand Registration (including the reasonable fees and disbursements of one counsel for such holders in connection with each such Demand Registration not to exceed $25,000 per registration, as described in SECTION 6). (d) SELECTION OF UNDERWRITERS. The holders of the Registrable Securities initiating a Demand Registration shall, after consultation with the Company, select the investment banker(s) and manager(s) that will administer the offering; PROVIDED, that the Company shall have given its prior written consent to such selection. The Company and the holders of Registrable Securities whose shares are being registered shall enter into a customary underwriting agreement with such investment banker(s) and manager(s). (e) PRIORITY ON DEMAND RESTRICTIONS. If the managing underwriter shall advise the Company, in writing or otherwise, that an underwriters' over-allotment option, not in excess of fifteen percent (15%) of the total offering to be so effected, is necessary or desirable for the marketing of such 5 offering, all Registrable Securities which are to be included in such offering pursuant to this SECTION 3(E) and any other securities shall be allocated pro rata to the primary portion of such offering and the underwriters' over-allotment portion on the basis of the total number of Registrable Securities and other securities requested to be included in the registration. If any holder of Registrable Securities (other than the holder making the demand) disapproves of the terms of the underwriting, such holder may withdraw therefrom by giving written notice to the Company and the managing underwriter. (f) DELAY IN FILING. Notwithstanding the foregoing, the Company may delay in filing a registration statement in connection with a Demand Registration and may withhold efforts to cause the registration statement to become effective, if the Company determines in good faith that such registration might involve initial or continuing disclosure obligations that the Board of Directors of the Company determines, in good faith, will not be in the best interest of the Company's stockholders. The Company may exercise such right to delay or withhold efforts not more than once in any twelve (12) month period and for not more than ninety (90) days at a time. If, after a registration statement becomes effective, the Company advises the holders of registered shares that the Company considers it appropriate for the registration statement to be amended, the Company shall use its best efforts to amend such registration statement, and the holders of such shares shall suspend any further sales of their registered shares until the Company advises them that the amended registration statement has been declared effective. (g) EFFECTIVE DEMAND REGISTRATION. A registration shall not constitute a Demand Registration until it has become effective and remains continuously effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and (ii) three hundred sixty (360) days; PROVIDED, HOWEVER, that a registration shall not constitute a Demand Registration if (x) after such Demand Registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason not attributable to the holder requesting the Demand Registration and such interference is not thereafter eliminated, or (y) the conditions specified in the underwriting agreement, if any, entered into in connection with such Demand Registration are not satisfied or waived, other than by reason of a failure on the part of the holder requesting the Demand Registration. SECTION 4. PIGGYBACK REGISTRATIONS. (a) RIGHT TO PIGGYBACK. Whenever the Company proposes to register any of its securities in an underwritten offering under the Securities Act, whether for its own account or for the account of another stockholder (except for the registration of securities to be offered pursuant to an employee benefit plan on Form S-8, pursuant to a registration made on Form S-4 or any successor forms then in effect) at any time other than pursuant to a Demand Registration and the registration form to be used may be used for the registration of the Registrable Securities (a "Piggyback Registration"), it will so notify in writing all holders of Registrable Securities no later than the earlier to occur of (i) the tenth (10th) day following the Company's receipt of notice of exercise of other demand registration rights, or (ii) forty-five (45) days prior to the anticipated filing date. Subject to the provisions of SECTION 4(C), the Company will include in the Piggyback Registration all Registrable Securities with respect to which the Company has received written requests for inclusion within 6 fifteen (15) days after the issuance of the Company's notice. Such Registrable Securities may be made subject to an underwriters' over-allotment option, if so requested by the managing underwriter. The holders of Registrable Securities may withdraw all or any part of the Registrable Securities from a Piggyback Registration at any time before ten (10) business days prior to the effective date of the Piggyback Registration. In any Piggyback Registration, the Company, the holders of Registrable Securities and any Person who hereafter becomes entitled to register its securities in a registration initiated by the Company must sell their securities on the same terms and conditions. A registration of Registrable Securities pursuant to this SECTION 4 shall not be counted as a Demand Registration pursuant to SECTION 3. (b) PIGGYBACK EXPENSES. The Company shall pay or reimburse to the holders of the Registrable Securities included in a Piggyback Registration all Registration Expenses of those holders in connection with the Piggyback Registration (including the reasonable fees and disbursements of one counsel for such holders in connection with each such Piggyback Registration not to exceed $25,000 per Piggyback Registration, as described in SECTION 6). (c) UNDERWRITING; PRIORITY ON PIGGYBACK REGISTRATIONS. The right of any such holder to be included in an underwritten registration pursuant to this SECTION 4 shall be conditioned upon such holder's participation in such underwriting and the inclusion of such holder's Registrable Securities in the underwriting to the extent provided herein. All holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. If the managing underwriter gives the Company its written opinion that the total number or dollar amount of securities requested to be included in the registration exceeds the number or dollar amount of securities that can be sold, the Company will include the securities in the registration in the following order of priority: (i) first, subject to the first proviso below, all securities the Company or the stockholder, if any, on whose account securities are being registered proposes to sell; (ii) second, subject to the first proviso below, up to the full number or dollar amount of Registrable Securities requested to be included in the registration (allocated pro rata among the holders of Registrable Securities requested to be included in the registration, on the basis of the dollar amount or number of Registrable Securities requested to be included, as the case may be); and (iii) third, any other securities (provided they are of the same class as the securities sold by the Company) requested to be included, allocated among the holders of such securities in such proportions as the Company and those holders may agree; PROVIDED, that at least twenty-five percent (25%) of the Registrable Securities requested to be included in such registration shall be included in the offering; PROVIDED, FURTHER, that, (i) the holders of Registrable Securities shall not be subject to any cutback in the amount of Registrable Securities requested to be included in the registration unless all other holders of securities requesting to be included in such registration other than the stockholder, if any, on whose account securities are being registered have been excluded from such registration. In the event that the managing underwriter advises the Company that an underwriters' over-allotment option is necessary or advisable, the allocation provided for in this SECTION 4(C) shall apply to the determination of which securities are to be included in the registration of such shares. Except with the prior written consent of each holder of Registrable Securities, the Company shall not grant to any holder of the Company's securities any right to Piggyback Registration which would reduce the amount of Registrable Securities includable in such registration. 7 (d) SELECTION OF UNDERWRITERS. If any Piggyback Registration is an underwritten offering, the Company will select as the investment banker(s) and manager(s) that will administer the offering a nationally recognized investment banker(s) and manager(s) with demonstrable industry-specific expertise and experience. The Company and the holders of Registrable Securities whose shares are being registered shall enter into a customary underwriting agreement with such investment banker(s) and manager(s), PROVIDED, that the liability of any holder of Registrable Securities shall be limited to such holder's net proceeds received from the sale of its Registrable Securities in such offering and such limitation shall not be amended by an underwriting agreement or arrangement. (e) RIGHT TO TERMINATE REGISTRATION. The Company shall have the right to terminate or withdraw any registration initiated by it under this SECTION 4 prior to the effectiveness of such registration whether or not any holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with SECTION 7 hereof. (f) OTHER REGISTRATIONS. The Company agrees that after filing a registration statement with respect to Registrable Securities pursuant to SECTION 3 or this SECTION 4 that has not been withdrawn or abandoned, the Company will not register any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act, whether on its own behalf or at the request of any holder of those securities until the earlier of (i) the sale of all such Registrable Securities subject to such registration statement and (ii) one hundred eighty (180) days from the effective date of the previous registration, and the parties hereto agree that the Company will not be required to effect any such registration notwithstanding the other provisions of this Agreement. This 180-day hiatus does not apply to registrations of securities (i) to be issued in connection with employee benefit plans, (ii) to permit exercise or conversions of previously issued options, warrants, or other convertible securities, (iii) in connection with a Demand Registration or (iv) made on Form S-4 (or any successor form).

Such indemnity shall remain in full force and effect, regardless of any investigation made by such indemnified party, and shall survive the transfer of such Registrable Securities by such holder. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, the Company will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the extent customary in such agreements. (b) INDEMNIFICATION BY HOLDERS OF SECURITIES. In connection with any registration statement, each participating holder of Registrable Securities will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any registration statement or prospectus. Each participating holder agrees, severally and not jointly, to indemnify and hold harmless, to the extent permitted by law, the Company, its directors, officers, trustees, partners, employees, advisors and agents, and each Person who controls the Company (within the meaning of the Securities Act and the Exchange Act) against any and all losses, claims, damages, liabilities and expenses arising out of any untrue or allegedly untrue statement of a material fact or any omission or alleged omission to state a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto necessary to make the statements therein not misleading, but only to the extent that the untrue statement or omission is contained in or omitted from any information or affidavit the holder furnished in writing to the Company expressly for use therein and only in an amount not exceeding the net proceeds received by the holder with respect to securities sold pursuant to such registration statement. Such indemnity shall remain in full force and effect, regardless of any investigation made by the Company, and shall survive the transfer of such Registrable Securities by such holder. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, each participating holder of Registrable Securities will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the same extent as it has indemnified the Company; PROVIDED, that the indemnity obligations of any holder contained in such agreement shall be limited to the amount of such holder's net proceeds received from the sale of its Registrable Securities in such offering. (c) INDEMNIFICATION PROCEEDINGS. Any Person entitled to indemnification under this Agreement will (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in the indemnified party's reasonable judgment a conflict of interest may exist between the indemnified and indemnifying parties with respect to the claim, permit the indemnifying party to assume the defense of the claim with counsel reasonably satisfactory to the indemnified party. If the indemnifying party does not assume the defense, the indemnifying party will not be liable for any settlement made without its consent (but that consent may not be unreasonably withheld). No indemnifying party will consent to entry of any judgment or will enter into any settlement that does not include as an unconditional term thereof the claimant's or plaintiff's release of the indemnified party from all liability concerning the claim or litigation or which includes any non-monetary settlement. An indemnifying party who is not entitled to or elects not to assume the defense of a claim will not be under an obligation to pay the fees and expenses of more than one counsel for all parties indemnified by the indemnifying party with respect to the claim, unless in the reasonable judgment of any indemnified party 12 a conflict of interest may exist between the indemnified party and any other indemnified party with respect to the claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of no more than one additional counsel for the indemnified parties. (d) CONTRIBUTION. IF THE INDEMNIFICATION PROVIDED FOR IN SECTION 7(A) OR (B) IS unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party thereunder shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the indemnified party and the indemnifying party shall be determined by 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 relates to information supplied by the indemnified party and the indemnifying party and the parties' relative intent and knowledge. The parties hereto agree that it would not be just and equitable if contribution pursuant to this SECTION 7(D) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding anything herein to the contrary, no participating holder of Registrable Securities acting as an indemnifying party shall be required to contribute any amount in excess of the amount by which the net proceeds of the offering (before deducting expenses, if any) received by such participating holder exceeds the amount of any damages that such participating holder 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 obligations of the Company and the holders of Registrable Securities under this SECTION 7 shall survive the completion of any offering of Registrable Securities in a registration statement, including the termination of this Agreement.
