ARTICLE II

REGISTRATIONS

2.01 Demand Registration. Subject to the restrictions set forth below, if at any time commencing three months prior to the Release Date, and from time to time thereafter, the Company shall receive from the Holders (the “Requesting Holders”) owning a majority in interest of the then outstanding shares of Registrable Securities as of the date of the request, a written request to register at least fifteen percent (15%) of the aggregate number of Registrable Securities owned by all of the Requesting Holders as of the date of such request, then the Company will give notice of such request to all Holders within ten (10) days of receiving such request and shall effect as soon thereafter as practicable, and in any event within forty-five (45) days of the receipt of such request, the Registration under the Securities Act of all Registrable Securities which any Holder requests to be registered. The Company shall not be obligated to effect, or to take any action to effect, any such Registration pursuant to this Section 2.01:

(a) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company initiated Registration; provided that the Company has delivered notice of such Registration to the Holders prior to its receipt of the Holders’ written request for a demand Registration and it continues to actively employ in good faith all reasonable efforts to cause such Registration Statement to become effective; or

(b) if the Holders have requested an Underwritten Registration, the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or

(c) if in the good faith judgment of the Board, such Registration would be seriously detrimental to the Company and the Board concludes, as a result, that it is essential to defer the filing of such Registration Statement at such time, and the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is, therefore, essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing (except as provided in subparagraph (a) above) for a period of not more than one hundred eighty (180) days after receipt of the request of the Holders; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period.

Notwithstanding the foregoing, the Company shall ensure that no such Registration shall become effective with respect to any Registrable Securities subject to an applicable Lock-up Period until after the expiration of the applicable Lock-up Period. Furthermore, the Company shall not be required to effect more than three (3) Registrations, which may be either Long-Form

- 5 -

Registrations or Short-Form Registrations, under this Section 2.01 on behalf of the Holders; provided, however, that a Registration shall not be counted for such purposes unless such Long-Form Registration has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Long-Form Registration have been sold, in accordance with Section 3.01(a) of this Agreement; and provided, further, however, that the Company will not be obligated to effect any such Short-Form Registration:

(a) if Form S-3 is not available for such offering;

(b) if in the good faith judgment of the Board, such Registration would be seriously detrimental to the Company and the Board concludes, as a result, that it is essential to defer the filing of such Registration Statement at such time, and the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is, therefore, essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing (except as provided in subparagraph (a) above) for a period of not more than one hundred eighty (180) days after receipt of the request of the Holders; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period;

(c) if the Company has effected one (1) Short-Form Registration within the six (6) month period prior to the current request for Short-Form Registration; or

(d) if the Registrable Securities to be covered by such registration statement do not, in the aggregate, exceed $500,000.

2.02 Piggyback Registration. Each time the Company decides to file a Registration Statement under the Securities Act other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing securityholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan, (v) filed in connection with the registration of Common Stock pursuant to Section 6(d) of the Warrant Agreement dated as of                     , 2008, by and between the Company and Continental Stock Transfer & Trust Company (the “Warrant Agreement”), or (vi) for the acquisition or purchase by or combination by merger or otherwise of the Company of or with another company or business entity or partnership, the Company shall give written notice thereof to the Holders as soon as practicable but in no event less than ten (10) business days before the intended filing date, which notice shall disclose the amount and type of securities to be included in such Registration Statement, the intended method(s) of distribution and the name of the proposed managing underwriter or underwriters, if any. The Company shall include in such Registration Statement such Registrable Securities for which it has received written requests for registration within ten (10) business days after such written notice has been given. If in the good faith judgment of the managing underwriter in any Underwritten Offering, the inclusion of all of the Registrable Securities and any other Common Stock (including shares of Common Stock issued or issuable upon the exercise or conversion of other securities of the Company) requested to be

- 6 -

registered by third parties holding similar registration rights (the “Other Securities”) would interfere with the successful marketing of a smaller number of such securities, then the number of Registrable Securities and Other Securities to be included in the offering (except for shares to be issued by the Company in an offering initiated by the Company) shall be reduced as provided herein. The Company shall advise all holders of securities requesting registration of the underwriters’ decision, and the number of securities that are entitled to be included in the Underwritten Registration shall be allocated first to the Company for securities being sold for its own account and thereafter as set forth in Section 2.03 below.

2.03 Registration Cutback. In any circumstance in which all of the Registrable Securities and Other Securities requested to be included in a Registration on behalf of the Holders or other selling stockholders cannot be so included as a result of limitations of the aggregate number of Registrable Securities and Other Securities that may be so included, the number of Registrable Securities and Other Securities that may be so included shall be allocated among the Holders and other selling stockholders requesting inclusion of Other Securities pro rata on the basis of the number of Registrable Securities and Other Securities that would be held by such Holders and other selling stockholders, assuming conversion. If any Holder or other selling stockholder does not request inclusion of the maximum number of shares of Registrable Securities and Other Securities allocated to such Holder or other selling stockholder pursuant to the above-described procedure, the remaining portion of such Holder’s or other selling stockholder’s allocation shall be reallocated among those requesting Holders and other selling stockholders whose allocations did not satisfy their requests, pro rata on the basis of the number of Registrable Securities and Other Securities which would be held by such Holders and other selling stockholders, assuming conversion, and this procedure shall be repeated until all of the shares of Registrable Securities and Other Securities which may be included in the registration on behalf of Holders and other selling stockholders have been so allocated.

2.04 Cancellation of Registration. A majority of the Requesting Holders shall have the right to cancel a proposed Registration of Registrable Securities pursuant to Section 2.01 when, (i) in their discretion, market conditions are so unfavorable as to be seriously detrimental to an offering pursuant to such Registration or (ii) the request for cancellation is based upon material adverse information relating to the Company that is different from the information known to the Requesting Holders at the time of their written request for a Demand Registration. Such cancellation of a Registration shall not be counted as one of the three (3) Registrations provided for in Section 2.01 above and, notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the expenses of the Requesting Holders incurred in connection with the Registration prior to the time of such cancellation.

2.05 Suspension of Registration. If the filing, initial effectiveness or continued use of a Registration Statement in respect of a Demand Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest possible period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to

- 7 -

above, their use of the prospectus relating to the Demand Registration in connection with any sale or offer to sell Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 2.05.

2.06 No Net Cash Settlement Value. In no event will the Holders be entitled to receive a net cash settlement or other consideration in lieu of physical settlement in shares of Common Stock, regardless of whether the Common Stock (or Common Stock underlying the Registrable Securities) is registered pursuant to an effective Registration Statement.

- 8 -

enable the disposition in such jurisdictions of the Registrable Securities covered by the Registration Statement; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be reporting under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (“Rule 144”), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

3.06 Indemnification.

(a) The Company agrees to indemnify, to the extent permitted by law, the Holder of Registrable Securities, its officers and directors and each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company will indemnify the underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holder.

(b) In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and, to the extent permitted by law, will indemnify the Company, its directors and officers and agents and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify will be several, not joint and several, among such Holders of

- 11 -

Registrable Securities, and the liability of each such Holder of Registrable Securities will be in proportion to and limited to the gross proceeds received by such Holder from the sale or Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities will indemnify the underwriters, their officers, directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to indemnification of the Company.

(c) Any Person entitled to indemnification herein will (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 materially 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 will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will 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. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and will survive the transfer of securities. The Company and each Holder of Registrable Securities participating in the offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

(e) If the indemnification provided for in this Section 3.06 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any

- 12 -

action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 3.06(e) shall be limited to the amount of the gross proceeds received by such Holder in the offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections (a) through (c) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 3.06(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 3.06(e). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 3.06(e) from any Person who was not guilty of such fraudulent misrepresentation.

(a) This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned by the Company in whole or in part. Prior to the expiration of the Lock-Up Period, this Agreement and the rights, duties and obligations of the Holders hereunder may be assigned by any Holder of Registrable Securities in conjunction with and to the extent of any valid transfer of such Registrable Securities by any such Holder. Following the expiration of the Lock-Up Period, only the Sponsor may assign or delegate its rights, duties and obligations hereunder in conjunction with and to the extent of any valid transfer of the Registrable Securities held by the Sponsor.

(b) No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 4.01 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in this Section 4.02 shall be null and void.

(c) This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and their respective successors and the permitted assigns of the Holders or of any assignee of the Holders. This Agreement is not intended to confer any rights or benefits on any persons not a party hereto other than as expressly set forth in this Section 4.02.

4.03 Counterparts. This Agreement may be executed in multiple counterparts (including facsimile counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced.

4.04 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG DELAWARE RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN DELAWARE, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION.

4.05 Amendments and Modifications. Upon the written consent of the Company and the Holders who hold at least fifty percent (50%) of the Registrable Securities, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

4.06 Other Registration Rights. Except for the registration of Common Stock pursuant to Section 6(d) of the Warrant Agreement, the Company will not grant to any Person the right to require the Company to register any equity securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, which conflicts with the registration rights granted hereunder.

4.07 Termination. This Agreement shall terminate and the registration rights granted hereunder shall expire on the date that is five (5) years after the Prospectus Date; provided that such termination and expiration shall not affect registration rights exercised prior to such date.
