The Company shall promptly (and, in any event, no more than 24 hours after it receives comments from the Commission), notify the Buyer when and if it receives any comments from the Commission on the Registration Statement and promptly forward a copy of such comments, if they are in writing, to the Buyer. At such time after the filing of the Registration Statement pursuant to this Section 2(A) as the Commission indicates, either orally or in writing, that it has no further comments with respect to such Registration Statement or that it is willing to entertain appropriate requests for acceleration of effectiveness of such Registration Statement, the Company shall promptly, and in no event later than two (2) business days after receipt of such indication from the Commission, request that the effectiveness of such Registration Statement be accelerated within forty-eight (48) hours of the Commission's receipt of such request. The Company shall notify the Initial Investor by written notice that such Registration Statement has been declared effective by the Commission within 24 hours of such declaration by the Commission.

(B) Eligibility for Use of Form S-3. The Company agrees that at such time as it meets all the requirements for the use of Securities Act Registration Statement on Form S-3 it shall file all reports and information required to be filed by it with the Commission in a timely manner and take all such other action so as to maintain such eligibility for the use of such form.

(C) Additional Registration Statement. In the event the Current Market Price declines to a price per share the result of which is that the Company cannot satisfy its conversion obligations to Initial Investor hereunder, the Company shall, to the extent required by the Securities Act (because the additional shares were not covered by the Registration Statement filed pursuant to Section 2(a)), as reasonably determined by the Initial Investor, file an additional Registration Statement with the Commission for such additional number of Registrable Securities as would be issuable upon conversion of the Debenture (the "Additional Registrable Securities") in addition to those previously registered. The Company shall, to the extent required by the Securities Act, as reasonably determined by the Initial Investor, prepare and file with the Commission not later than the 30th day thereafter, a Registration Statement relating to the offer and sale of such Additional Registrable Securities and shall use its best efforts to cause the Commission to declare such Registration Statement effective under the Securities Act as promptly as practicable but not later than 60 days thereafter. The Company shall not include any other securities in the Registration Statement relating to the offer and sale of such Additional Registrable Securities.

(D) (i)	If the Company proposes to register any of its warrants, Common Stock or any other shares of common stock of the Company under the Securities Act (other than a registration (A) on Form S-8 or S-4 or any successor or similar forms, (B) relating to Common Stock or any other shares of common stock of the Company issuable upon exercise of employee share options or in connection with any employee benefit or similar plan of the Company or (C) in connection with a direct or indirect acquisition by the Company of another Person or any transaction with respect to which Rule 145 (or any successor provision) under the Securities Act applies), whether or not for sale for its own account, it will each such time, give prompt written notice at least 20 days prior to the anticipated filing date of the registration statement relating to such registration to each Investor, which notice shall set forth such Investor's rights under this Section 2(D) and shall offer such Investor the opportunity to include in such registration statement such number of Registrable Securities as such Investor may request. Upon the written request of any Investor made within 10 days after the receipt of notice from the Company (which request shall specify the number of Registrable Securities intended to be disposed of by such Investor), the Company will use its best efforts to effect the registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by each Investor, to the extent requisite to permit the disposition of the Registrable Securities so to be registered; provided, however, that (A) if such registration involves a Public Offering, each Investor must sell its Registrable Securities to any underwriters selected by the Company with the consent of such Investor on the same terms and conditions as apply to the Company and (B) if, at any time after giving written notice of its intention to register any Registrable Securities pursuant to this Section 2 and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register such Registrable Securities, the Company shall give written notice to each Investor and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. The Company's obligations under this Section 2(D) shall terminate on the date that the registration statement to be filed in accordance with Section 2(A) is declared effective by the Commission.

(ii) If a registration pursuant to this Section 2(D) involves a Public Offering and the managing underwriter thereof advises the Company that, in its view, the number of shares of Common Stock that the Company and the Investors intend to include in such registration exceeds the largest number of shares of Common Stock that can be sold without having an adverse effect on such Public Offering (the "Maximum Offering Size"), the Company will include in such registration only such number of shares of Common Stock as does not exceed the Maximum Offering Size, and the number of shares in the Maximum Offering Size shall be allocated among the Company, the Investors and any other sellers of Common Stock in such Public Offering ("Third-Party Sellers"), first, pro rata among the Investors until all the shares of Common Stock originally proposed to be offered for sale by the Investors have been allocated, and second, pro rata among the Company and any Third-Party Sellers, in each case on the basis of the relative number of shares of Common Stock originally proposed to be offered for sale under such registration by each of the Investors, the Company and the Third-Party Sellers, as the case may be. If as a result of the proration provisions of this Section 2(D)(ii), any Investor is not entitled to include all such Registrable Securities in such registration, such Investor may elect to withdraw its request to include any Registrable Securities in such registration. With respect to registrations pursuant to this Section 2(D), the number of securities required to satisfy any underwriters' over-allotment option shall be allocated among the Company, the Investors and any Third Party Seller pro rata on the basis of the relative number of securities offered for sale under such registration by each of the Investors, the Company and any such Third Party Sellers before the exercise of such over-allotment option.

3. Obligations of the Company

In connection with the registration of the Registrable Securities, the Company shall:

(G) Cause all the Registrable Securities covered by the Registration Statement to be listed on the principal national securities exchange, and included in an inter-dealer quotation system of a registered national securities association, on or in which securities of the same class or series issued by the Company are then listed or included;

(J) Take all such other lawful actions reasonably necessary to expedite and facilitate the disposition by the Investors of their Registrable Securities in accordance with the intended methods therefor provided in the Prospectus which are customary under the circumstances;

(B) Indemnification by the Investors and Underwriters. Each Investor agrees, as a consequence of the inclusion of any of its Registrable Securities in a Registration Statement, and each underwriter, if any, which facilitates the disposition of Registrable Securities shall agree, as a consequence of facilitating such disposition of Registrable Securities, severally and not jointly, to (i) indemnify and hold harmless the Company, its directors (including any person who, with his or her consent, is named in the Registration Statement as a director nominee of the Company), its officers who sign any Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or such other persons may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such Registration Statement or Prospectus or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made, in the case of the Prospectus), not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such holder or underwriter expressly for use therein; provided, however, that no Investor or underwriter shall be liable under this Section 6(B) for any amount in excess of the net proceeds paid to such Investor or underwriter in respect of shares sold by it and (ii) reimburse the Company for any legal or other expenses incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(C) Notice of Claims, etc. Promptly after receipt by a party seeking indemnification pursuant to this Section 6 (an "Indemnified Party") of written notice of any investigation, claim, proceeding or other action in respect of which indemnification is being sought (each, a "Claim"), the Indemnified Party promptly shall notify the party against whom indemnification pursuant to this Section 6 is being sought (the "Indemnifying Party") of the commencement thereof; but the omission to so notify the Indemnifying Party shall not relieve it from any liability that it otherwise may have to the Indemnified Party, except to the extent that the Indemnifying Party is materially prejudiced and forfeits substantive rights and defenses by reason of such failure. In connection with any Claim as to which both the Indemnifying Party and the Indemnified Party are parties, the Indemnifying Party shall be entitled to assume the defense thereof. Notwithstanding the assumption of the defense of any Claim by the Indemnifying Party, the Indemnified Party shall have the right to employ separate legal counsel and to participate in the defense of such Claim, and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs and expenses of such separate legal counsel to the Indemnified Party if (and only if): (x) the Indemnifying Party shall have agreed to pay such fees, costs and expenses, (y) the Indemnified Party and the Indemnifying Party shall reasonably have concluded that representation of the Indemnified Party by the Indemnifying Party by the same legal counsel would not be appropriate due to actual or, as reasonably determined by legal counsel to the Indemnified Party, potentially differing interests between such parties in the conduct of the defense of such Claim, or if there may be legal defenses available to the Indemnified Party that are in addition to or disparate from those available to the Indemnifying Party or (z) the Indemnifying Party shall have failed to employ legal counsel reasonably satisfactory to the Indemnified Party within a reasonable period of time after notice of the commencement of such Claim. If the Indemnified Party employs separate legal counsel in circumstances other than as described in clauses (x), (y) or (z) above, the fees, costs and expenses of such legal counsel shall be borne exclusively by the Indemnified Party. Except as provided above, the Indemnifying Party shall not, in connection with any Claim in the same jurisdiction, be liable for the fees and expenses of more than one firm of counsel for the Indemnified Party (together with appropriate local counsel). The Indemnified Party shall not, without the prior written consent of the Indemnifying Party (which consent shall not unreasonably be withheld), settle or compromise any Claim or consent to the entry of any judgment that does not include an unconditional release of the Indemnifying Party from all liabilities with respect to such Claim or judgment.

(D) Contribution. If the indemnification provided for in this Section 6 is unavailable to or insufficient to hold harmless an Indemnified Person under subsection (A) or (B) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the Indemnified Party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), 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 the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such Indemnifying Party or by such Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 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 (even if the Investors or any underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(D). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. 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 Investors and any underwriters in this Section 6(D) to contribute shall be several in proportion to the percentage of Registrable Securities registered or underwritten, as the case may be, by them and not joint.

(E) Notwithstanding any other provision of this Section 6, in no event shall any (i) Investor be required to undertake liability to any person under this Section 6 for any amounts in excess of the dollar amount of the proceeds to be received by such Investor from the sale of such Investor's Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) pursuant to any Registration Statement under which such Registrable Securities are to be registered under the Securities Act and (ii) underwriter be required to undertake liability to any Person hereunder for any amounts in excess of the aggregate discount, commission or other compensation payable to such underwriter with respect to the Registrable Securities underwritten by it and distributed pursuant to the Registration Statement.

(F) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have to any Indemnified Person and the obligations of any Indemnified Person under this Section 6 shall be in addition to any liability which such Indemnified Person may otherwise have to the Company. The remedies provided in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to an indemnified party at law or in equity.

7. Rule 144

With a view to making available to the Investors the benefits of Rule 144 under the Securities Act or any other similar rule or regulation of the Commission that may at any time permit the Investors to sell securities of the Company to the public without registration ("Rule 144"), the Company agrees to use its best efforts to:

(1) comply with the provisions of paragraph (c) (1) of Rule 144 and

(2) file with the Commission in a timely manner all reports and other documents required to be filed by the Company pursuant to Section 13 or 15(d) under the Exchange Act; and, if at any time it is not required to file such reports but in the past had been required to or did file such reports, it will, upon the request of any Investor, make available other information as required by, and so long as necessary to permit sales of, its Registrable Securities pursuant to Rule 144.

8. Assignment

The rights to have the Company register Registrable Securities pursuant to this Agreement shall be automatically assigned by the Investors to any permitted transferee of all or any portion of such Registrable Securities (or all or any portion of the Debenture or Warrant of the Company which is convertible into such securities) only if (a) the Investor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (b) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (i) the name and address of such transferee or assignee and (ii) the securities with respect to which such registration rights are being transferred or assigned, (c) immediately following such transfer or assignment, the securities so transferred or assigned to the transferee or assignee constitute Restricted Securities and (d) at or before the time the Company received the written notice contemplated by clause (b) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein.

9. Amendment and Waiver

Any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Investors who hold a majority-in-interest of the Registrable Securities. Any amendment or waiver effected in accordance with this Section 9 shall be binding upon each Investor and the Company.

10. Changes in Common Stock

If, and as often as, there are any changes in the Common Stock by way of stock split, stock dividend, reverse split, combination or reclassification, or through merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof, as may be required, so that the rights and privileges granted hereby shall continue with respect to the Common Stock as so changed.

11. Miscellaneous

(A) A person or entity shall be deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more persons or entities with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

(B) If, after the date hereof and prior to the Commission declaring the Registration Statement to be filed pursuant to Section 2(a) effective under the Securities Act, the Company grants to any Person any registration rights with respect to any Company securities which are more favorable to such other Person than those provided in this Agreement, then the Company forthwith shall grant (by means of an amendment to this Agreement or otherwise) identical registration rights to all Investors hereunder.

(C) Except as may be otherwise provided herein, any notice or other communication or delivery required or permitted hereunder shall be in writing and shall be delivered personally, or sent by telecopier machine or by a nationally recognized overnight courier service, and shall be deemed given when so delivered personally, or by telecopier machine or overnight courier service as follows:

The Company, the Initial Investor or any Investor may change the foregoing address by notice given pursuant to this Section 11(C).

(D) Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

(E) This Agreement shall be governed by and interpreted in accordance with the laws of the State of California. Each of the parties consents to the jurisdiction of the federal courts whose districts encompass any part of the City of San Diego or the state courts of the State of California sitting in the City of San Diego in connection with any dispute arising under this Agreement and hereby waives, to the maximum extent permitted by law, any objection including any objection based on forum non conveniens, to the bringing of any such proceeding in such jurisdictions.

(F) The remedies provided in this Agreement are cumulative and not exclusive of any remedies provided by law. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(G) The Company shall not enter into any agreement with respect to its securities that is inconsistent with the rights granted to the holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The Company is not currently a party to any agreement granting any registration rights with respect to any of its securities to any person which conflicts with the Company's obligations hereunder or gives any other party the right to include any securities in any Registration Statement filed pursuant hereto, except for such rights and conflicts as have been irrevocably waived. Without limiting the generality of the foregoing, without the written consent of the holders of a majority in interest of the Registrable Securities, the Company shall not grant to any person the right to request it to register any of its securities under the Securities Act unless the rights so granted are subject in all respect to the prior rights of the holders of Registrable Securities set forth herein, and are not otherwise in conflict or inconsistent with the provisions of this Agreement. The restrictions on the Company's rights to grant registration rights under this paragraph shall terminate on the date the Registration Statement to be filed pursuant to Section 2(A) is declared effective by the Commission.

(H) This Agreement, the Securities Purchase Agreement, of even date herewith among the Company, the Initial Investor and Loeb & Loeb LLP, and the Debenture constitute the entire agreement among the parties hereto with respect to the subject matter hereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein. This Agreement, the Securities Purchase Agreement, and the Debenture supersede all prior agreements and undertakings among the parties hereto with respect to the subject matter hereof.

(I) Subject to the requirements of Section 8 hereof, this Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties hereto.

(J) All pronouns and any variations thereof refer to the masculine, feminine or neuter, singular or plural, as the context may require.

(K) The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning thereof.

(L) The Company acknowledges that any failure by the Company to perform its obligations under Section 3, or any delay in such performance, could result in direct damages to the Investors and the Company agrees that, in addition to any other liability the Company may have by reason of any such failure or delay, the Company shall be liable for all direct damages caused by such failure or delay.

(M) This Agreement may be executed in two (2) counterparts, each of which shall be deemed an original but both of which shall constitute one and the same agreement. A facsimile transmission of this signed Agreement shall be legal and binding on the parties hereto.

IN WITNESS WHEREOF, the parties hereto have duly caused this Agreement to be executed and delivered on the date first above written.
