4

the public resale of all Registrable Securities from time to time as permitted by Rule 415 (or any successor or similar provision adopted by the Commission then in effect) under the Securities Act, on the terms and conditions specified in this Section 2(a)(i) (a “Shelf Registration Statement”).

The Company shall use its reasonable best efforts to cause the Shelf Registration Statement filed pursuant to this Section 2(a)(i) to become or be declared effective 90 days after the Closing Date. The Shelf Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of Registrable Securities covered by such Shelf Registration Statement. During the Effectiveness Period, the Company shall use its reasonable best efforts to cause such Shelf Registration Statement filed pursuant to this Section 2(a)(i) to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Shelf Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until all  Registrable Securities have ceased to be Registrable Securities (the “Effectiveness Period”). The Shelf Registration Statement when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Shelf Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Shelf Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Company shall provide the Holders with written notice of the effectiveness of the Shelf Registration Statement.

(ii)          In the event a Holder transfers Registrable Securities included on the Shelf Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the request of such Holder, the Company shall amend or supplement such Shelf Registration Statement as may be necessary in order to enable such transferee to offer and sell such Registrable Securities pursuant to such Shelf Registration Statement; provided that in no event shall the Company be required to file a post-effective amendment to the Shelf Registration Statement unless (A) such Shelf Registration Statement includes only Registrable Securities held by the Holder, Affiliates of the Holder or transferees of the Holder or (B) the Company has received written consent therefor from whom Registrable Securities have been registered on (but not yet sold under) such Shelf Registration Statement, other than the Holder, Affiliates of the Holder or transferees of the Holder.

(b)                                 Piggyback Registration.

(i)             So long as a Holder has Registrable Securities, if the Company shall at any time propose to conduct a public offering of Common Stock for cash (whether in connection with a public offering of Common Stock by the Company, a public offering of Common Stock by stockholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on

5

Form S-4 or S-8 or an offering on any registration statement form that does not permit secondary sales), the Company shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days before) the commencement of the offering (the “Piggyback Notice”). The Piggyback Notice shall offer to each Holder holding at least $1.25 million of Registrable Securities based on the VWAP of such Registrable Securities on the date of such Piggyback Notice the opportunity to include for registration in such Registration Statement the number of Registrable Securities as they may request (a “Piggyback Registration”). The Company shall use commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which the Company has received a written request from a Holder within three Business Days after delivery of the Piggyback Notice to such Holder (“Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Registrable Securities in any Registration Statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of Common Stock, all upon the terms and conditions set forth herein.

(ii)  If the Registration Statement under which the Company gives notice under this Section 2(b) is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 2(b) 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 or managing underwriters of such offering advise the Company and the Holders in writing that in their reasonable opinion that the inclusion of all of the Holders’ Registrable Securities in the subject Registration Statement (or any other Common Stock proposed to be included in such offering) would likely have an adverse effect in any material respect on the price, timing or distribution of Common Stock proposed to be included in such offering, the Company shall include in such offering only that number of shares of Common Stock proposed to be included in such offering that, in the reasonable opinion of the managing underwriter or managing underwriters, will not have such effect, with such number to be allocated as follows:

(A)                               If such registration statement is filed other than pursuant to a demand registration initiated by the Preferred Holders pursuant to the terms of the Preferred Registration Rights Agreement, (i) first, to the Company, (ii) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata among the Preferred Holders desiring to register Preferred Registrable Securities based on the number of Preferred Registrable Securities held by all such Preferred Holders, (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro rata among the Citrus Holders desiring to register Citrus Registrable Securities based on the number of Citrus Registrable Securities held by all such Citrus Holders, (iv) if there remains availability for additional shares of Common Stock to be included in such registration, fourth pro rata among all Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders and (v) if there remains availability for additional shares of Common Stock to be included in such registration, fifth pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

(B)                               If such registration statement is filed pursuant to a demand registration initiated by the Preferred Holders pursuant to the terms of the Preferred Registration Rights Agreement, (i) first, to the Preferred Holders, (ii) if there remains availability for additional shares of Common Stock to be included in

6

such registration, second pro rata to the Citrus Holders desiring to register Citrus Registrable Securities based on the number of Citrus Registrable Securities held by all such Citrus Holders, (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro rata to the Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders, and (iv) if there remains availability for additional shares of Common Stock to be included in such registration, fourth pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering. Any Registrable Securities withdrawn from such underwriting shall be excluded and withdrawn from the registration.

(iii)       The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2(b) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration Statement.  Unless otherwise agreed to by a Holder with the Company, any Holder that has elected to include Registrable Securities in a Piggyback Registration shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Securities in such offering by giving written notice to the Company of such withdrawal at or prior to the time of pricing of such offering. The registration expenses of such withdrawn registration shall be borne by the Company in accordance with Section 4 hereof.

(iv)      The rights of the Holders under this Section 2(b) shall terminate upon such Holder (together with its Affiliates) ceasing to hold at least $1.25 million of Registrable Securities based on the Common Stock Price.

3.                                      Registration Procedures.

8

of material fact or omitting to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading).

(f)                                   The Company will use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as promptly as reasonably practicable, or if any such order or suspension is made effective during any Suspension Period, as promptly as reasonably practicable after such Suspension Period is over.

(c)                                  Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.  Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

(d)                                 If the indemnification provided for in this Section 5 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such 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 Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other 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 has been made by, or relates to, information supplied by such 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 contributions pursuant to this paragraph were to be determined by pro

11

rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating, defending or resolving any Loss that is the subject of this paragraph. 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 is not guilty of such fraudulent misrepresentation.

(e)                                  Other Indemnification. The provisions of this Section 5 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

6.                                      Miscellaneous.

(a)                                 Remedies. Any Person having rights under any provision of this Agreement shall be entitled to enforce such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or other security) for specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this Agreement.

(b)                                 Discontinued Disposition. Each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e) (a “Suspension Notice”), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section 3(j) or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”). The Company may provide appropriate stop orders to enforce the provisions of this Section 6(b).

(c)                                  Recapitalization, Exchanges, Etc. Affecting the Shares. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of, the Registrable Securities, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions of securities and the like occurring after the date of this Agreement

(d)                                 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to:

(i)                                     make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 (or any successor or similar provision adopted by the Commission then in effect) under the Securities Act, at all times from and after the date hereof;

12

(ii)                                  use its reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(iii)                               so long as a Holder owns any Registrable Securities, furnish, unless otherwise available electronically at no additional charge via the Commission’s EDGAR system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

(e) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended or waived only upon the prior written consent of the Company and the Holders of at least a majority of the outstanding Registrable Securities as of the date of such amendment or waiver.  No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right.

(f)                                   Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. Except as provided in this Section 6(f), this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of the Company and the Holders. Notwithstanding anything in the foregoing to the contrary, the rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (i) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this Agreement. The Company may not assign its rights or obligations hereunder without the prior written consent of the Funds (to the extent such Fund(s) is currently a Holder).

(g)                                  Severability.  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 shall use their reasonable 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.

(h)                                 Counterparts. This Agreement may be executed simultaneously in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement.

(i)                                     Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

13

(j)                                    Limitation on Subsequent Registration Rights.  From and after the date hereof, the Company shall not, without the prior written consent of the Holders of at least a majority of the then outstanding Registrable Securities, enter into any agreement with any current or future holder of any securities of the Company that would allow such current or future holder to require the Company to include securities in any registration statement filed by the Company on a basis other than expressly subordinate to the rights of, the Holders of Registrable Securities hereunder.

(k)                                 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof. Each of the Parties irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in the Borough of Manhattan in the City of New York and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

(l)                                     Notices. All notices and communications required or permitted to be given hereunder shall be in writing and shall be delivered personally, or sent by bonded overnight courier, or mailed by U.S. Express Mail or by certified or registered United States Mail with all postage fully prepaid, or sent by electronic mail (“email”) transmission (provided that a receipt of such email is requested and received), addressed to the appropriate Party at the address for such Party shown below or at such other address as such Party shall have theretofore designated by written notice delivered to the Party giving such notice:

14

(m)                             Legend Removal.  Certificates (or electronic versions thereof to the extent the Shares are held in book-entry form) evidencing the Shares shall not contain any legend: (i) following any sale of the Shares pursuant to Rule 144 or any resale of the Shares pursuant to a registration statement (including the Registration Statement), (ii) following the six-month anniversary of the Closing Date if the Shares are eligible for sale under Rule 144 without volume or manner-of-sale restrictions and as of such date the Company is in compliance with the current public information required under Rule 144 as to the Shares, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) (each such event being a “Legend Removal Qualification Event”). Upon request, the Company shall cause its counsel to issue a legal opinion to the Transfer Agent, if required by the Transfer Agent, promptly after a Legend Removal Qualification Event and the delivery to the Company or the Company’s counsel of any reasonable certifications requested by the Company or the Company’s counsel in connection with the issuance of such opinion to effect the removal of the legend hereunder with respect to any qualifying Shares. Following an applicable Legend Removal Qualification Event, the Company will no later than three (3) trading days following the delivery by a Holder to the Company or the Transfer Agent (with notice to the Company) of a legended certificate representing the Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) or an electronic version thereof (to the extent the Shares are held in book-entry form) and any reasonable certifications from the Holder requested by the Company or the Company’s counsel in order to effectuate a legend removal, deliver or cause to be delivered to such Holder a certificate representing such Shares that is free from all restrictive and other legends (or to the extent the Shares are held in book-entry form, effect the removal of restrictive and other legends on such Shares held by the Depository Trust Company).  In addition, promptly upon request of a Holder, the Company shall cause its counsel to promptly, but in no event later than two (2) trading days after such request and the delivery to the Company or the Company’s counsel of any reasonable certifications requested by the Company or the Company’s counsel, issue a legal opinion to the Transfer Agent at any time after the six month anniversary of the Closing Date if required by the Transfer Agent to transfer any of the Shares, which legal opinion shall provide that a Holder may transfer any of the Shares free of restriction during the 10 trading days following the date of such legal opinion and that the transferee thereof shall receive the Shares free from all restrictive and other legends.  The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Agreement.  Certificates for Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company System as directed by such Holder if the Company is then a participant in such system.

(n)                                 Entire Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and the matters addressed or governed hereby, whether oral or written.
