2.1                                 Current Public Information.  The Company covenants that it will use its best efforts to file all reports required to be filed by it under the Exchange Act and will use its reasonable best efforts to take such further action as the Holders may reasonably request, all to the extent required to enable the Holders to sell Registrable Securities pursuant to Rule 144 adopted by the SEC under the Securities Act or any similar rule or regulation hereafter adopted by the SEC.  The Company shall, upon the request of a Holder, deliver to such Holder a written statement as to whether it has complied with such requirements during the twelve month period immediately preceding the date of such request.

(a)       At any time after the one year anniversary of this Agreement and upon the written request of the Majority Holders, requesting that the Company effect the registration under the Securities Act of all or part of such Holders’ Registrable Securities and specifying the intended method of disposition thereof (the “Demand Notice”), the Company will promptly give written notice of such requested registration to all Holders, and thereupon the Company will use its reasonable best efforts to file with the SEC as soon as reasonably practicable following the

3

Demand Notice (but in no event later than the date that is 90 days after the Demand Notice) a Registration Statement.  The Company shall use its reasonable best efforts to cause such Registration Statement to be declared effective by the SEC within 90 days after the initial filing of the Registration Statement, and if such Registration Statement is not declared effective within 90 days after its initial filing, as soon as possible thereafter.  The Company shall include in such Registration Statement:

(i)                                     the Registrable Securities which the Holders have requested to be registered by the Company for disposition in accordance with the intended method of disposition stated in such request;

(ii)                                  all other Registrable Securities the holders of which shall have made a written request to the Company for registration thereof within 30 days after the giving of such written notice by the Company (which request shall specify the intended method of disposition of such Registrable Securities); and

(iii)                               all shares of Common Stock which the Company or Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company may elect to register in connection with the offering of Registrable Securities pursuant to this Section 2.2;

all to the extent requisite to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities and the additional shares of Common Stock, if any, so to be registered; provided, that, the provisions of this Section 2.2 shall not require the Company to effect more than one registration of Registrable Securities.

(b)                                 Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to effect a registration pursuant to this Section 2.2 within 180 days following the effective date of a registration statement filed by the Company in accordance with Section 2.3 for the account of another Holder of Registrable Securities if the Holders were afforded the opportunity to include the Registrable Securities in such registration.

(c)          The registration under this Section 2.2 shall be on an appropriate Registration Statement that permits the disposition of such Registrable Securities in accordance with the intended methods of distribution specified by the Majority Holders in their request for registration.  The Company agrees to include in any such Registration Statement all information which Holders of Registrable Securities being registered shall reasonably request to effect the registration.

(d)         A registration requested pursuant to this Section 2.2 shall not be deemed to have been effected (i) unless a Registration Statement with respect thereto registering all of the Registrable Securities initially included on such Registration Statement pursuant to Section 2.2(a)(i) and (ii) has become effective; provided, that a Registration Statement which does not become effective after the Company has filed a Registration Statement with respect thereto solely by reason of the refusal to proceed of the Majority Holders (other than a refusal to proceed based upon the advice of counsel relating to a matter with respect to the Company) or because of a breach of this Agreement by any Holder shall be deemed to have been effected by the

4

Company at the request of the Majority Holders unless the Holders electing to have Registrable Securities registered pursuant to such Registration Statement shall have elected to pay all fees and expenses otherwise payable by the Company in connection with such registration pursuant to Section 2.7, (ii) if, after it has become effective, such registration is withdrawn by the Company (other than at the request of the Majority Holders) or interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason prior to the expiration of a 180 day period following such Registration Statement’s effectiveness; provided, however, that the Company shall remain obligated to use its reasonable best efforts to obtain the withdrawal of such stop order and otherwise undertake its obligations as set forth in Section 2.5 with respect to such Registration Statement, or (iii) if the conditions to closing specified in any purchase agreement or underwriting agreement entered into in connection with such registration are not satisfied, other than due solely to some act or omission by the Holders electing to have Registrable Securities registered pursuant to such Registration Statement.

(e)          If the requested registration pursuant to this Section 2.2 involves an underwritten offering, and the managing underwriter shall advise the Company in writing (with a copy to each Holder of Registrable Securities requesting registration) that, in its opinion, the number of securities requested to be included in such registration (including securities of the Company which are not Registrable Securities) exceeds the number which can be sold in such offering within a price range reasonably acceptable to the Company and to the holders of a majority (by number of shares) of the Registrable Securities requested to be included in such Registration Statement, the Company will include in such registration, to the extent of the number which the Company is so advised can be sold in such offering, (i) first, the Registrable Securities which have been requested to be included in such registration by the Holders pursuant to this Agreement (pro rata based on the amount of Registrable Securities sought to be registered by such Persons), (ii) second, provided that no securities sought to be included by the Holders have been excluded from such registration, the securities of other Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company (pro rata based on the amount of securities sought to be registered by such Persons) and (iii) third, securities the Company proposes to register.

(f)            The Company shall use its reasonable best efforts to keep any Registration Statement filed pursuant to this Section 2.2 continuously effective until the Registrable Securities registered pursuant to such Registration Statement cease to constitute Registrable Securities.

(g)         The Company shall have the right at any time, to suspend the filing of a Registration Statement under this Section 2.2 or require that the Holders of Registrable Securities suspend further open market offers and sales of Registrable Securities pursuant to a Registration Statement filed hereunder for a period not to exceed an aggregate of 30 days in any six month period or an aggregate of 60 days in any twelve-month period for valid business reasons (not including avoidance of their obligations hereunder) (i) to avoid premature public disclosure of a pending corporate transaction, including pending acquisitions or divestitures of assets, mergers and combinations and similar events; (ii) upon the occurrence of any of the events specified in Section 2.5(e), until the time that the Holders receive copies of a supplement or amendment to the prospectus included in the applicable Registration Statement as contemplated in

5

Section 2.5(e); and (iii) upon the occurrence of any of the events specified in Section 2.5(i), until the time the Company notifies the Holders in writing that such suspension is no longer effective.

2.3                                 Piggyback Registration.

(a)       Whenever the Company proposes to register any of its securities under the Securities Act (other than pursuant to a registration pursuant to Section 2.2, a registration on Form S-4 or S-8 or any successor or similar forms, or the initial registration statement, or any subsequent registration statement, related to a rights offering by the Company) and the registration form to be used may be used for the registration of Registrable Securities, whether or not for sale for its own account, the Company will give prompt written notice (but in no event less than 30 days before the anticipated filing date) to all Holders (other than Holders all of whose Registrable Securities are then covered by an effective Registration Statement), and such notice shall describe the proposed registration and distribution and offer to all such Holders the opportunity to register the number of Registrable Securities as each such Holder may request.  The Company will include in such registration statement all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 15 days after the Holders’ receipt of the Company’s notice (a “Piggyback Registration”).

(b)      The Company shall use its reasonable best efforts to cause the managing underwriter or underwriters of a proposed underwritten offering involving a Piggyback Registration to permit the Registrable Securities requested to be included in a Piggyback Registration to be included on the same terms and conditions as any similar securities of the Company or any other security holder included therein and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method of distribution thereof.

(c)       Any Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any Registration Statement pursuant to this Section 2.3 by giving written notice to the Company of its request to withdraw; provided, that in the event of such withdrawal (other than pursuant to Section 2.3(e) hereof), the Company shall not be required to reimburse such Holder for the fees and expenses referred to in Section 2.7 hereof incurred by such Holder prior to such withdrawal, unless such withdrawal was due to a material adverse change to the Company.  The Company may withdraw a Piggyback Registration at any time prior to the time it becomes effective.

(d)      If (i) a Piggyback Registration involves an underwritten offering of the securities being registered, whether or not for sale for the account of the Company, to be distributed (on a firm commitment basis) by or through one or more underwriters of recognized standing under underwriting terms appropriate for such a transaction, and (ii) the managing underwriter of such underwritten offering shall inform the Company and Holders requesting such registration by letter of its belief that the distribution of all or a specified number of such Registrable Securities concurrently with the securities being distributed by such underwriters would interfere with the successful marketing of the securities being distributed by such underwriters (such writing to state the basis of such belief and the approximate number of such Registrable Securities which may be distributed without such effect), then the Company will be required to include in such registration only the amount of securities which it is so advised should be included in such registration.  In such event: (x) in cases initially involving the

6

registration for sale of securities for the Company’s own account, securities shall be registered in such offering in the following order of priority: (i) first, the securities which the Company proposes to register, and (ii) second, Registrable Securities and securities which have been requested to be included in such registration by Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company (pro rata based on the amount of securities sought to be registered by Holders and such other Persons); and (y) in cases not initially involving the registration for sale of securities for the Company’s own account, securities shall be registered in such offering in the following order of priority: (i) first, the securities of any Person whose exercise of a “demand” registration right pursuant to a contractual commitment of the Company is the basis for the registration, (ii) second, Registrable Securities and securities which have been requested to be included in such registration by Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company (pro rata based on the amount of securities sought to be registered by Holders and such other Persons), and (iii) third, the securities which the Company proposes to register.

(e)       If, as a result of the proration provisions of this Section 2.3, any Holder shall not be entitled to include all Registrable Securities in a Piggyback Registration that such Holder has requested to be included, such holder may elect to withdraw his request to include Registrable Securities in such registration.

(f)         The right of the Holders to register Registrable Securities pursuant to this Section 2.3 is only exercisable with respect to Registrable Securities not then covered by an effective Registration Statement.

2.4                                 Underwriting; Holdback Agreements.

(a)       In the event that one or more Holders elect to dispose of Registrable Securities under a Registration Statement pursuant to an underwritten offering or a requested registration pursuant to Section 2.2 involves an underwritten offering, the managing underwriter or underwriters shall be selected by the holders of a majority (by number of shares owned) of the Registrable Securities to be sold in the underwritten offering or requested to be included in such Registration Statement and shall be reasonably acceptable to the Company.  In connection with any such underwritten offering, the Company shall take all such reasonable actions as are required by the managing underwriters in order to expedite and facilitate the registration and disposition of the Registrable Securities, including the Company causing appropriate executive officers of the Company or its Affiliates to participate in a “road show” or similar marketing effort being conducted by such managing underwriters with respect to such underwritten offering.

(b)      All Holders proposing to distribute their Registrable Securities through an underwritten offering shall enter into an underwriting agreement in customary form with the managing underwriters selected for such underwritten offering.

(c)       To the extent not inconsistent with applicable law, in connection with a public offering of securities of the Company, upon the request of the Company or, in the case of an underwritten public offering of the Company’s securities, the managing underwriters, each Holder who beneficially owns (as defined in Rule 13d-3 adopted by the SEC under the Exchange

7

Act) at least 5% of the outstanding capital stock of the Company will not effect any sale or distribution (other than those included in the registration statement being filed with respect to such public offering) of, or any short sale of, or any grant of option to purchase, or any hedging or similar transaction with respect to, any securities of the Company, or any securities, options or rights convertible into or exchangeable or exercisable for such securities during the 14 days prior to and the 90-day period beginning on the effective date of such public offering, unless the Company, or in the case of an underwritten public offering, the managing underwriters otherwise agree to a shorter period of time.  At the request of the Company or the managing underwriters, each such Holder shall execute a customary “lock-up” agreement consistent with the provisions of this Section 2.4; provided, however, that no Holder shall be required to enter into any such “lock up” agreement unless and until all of the Company’s executive officers and directors execute substantially similar “lock up” agreements and the Company uses commercially reasonable efforts to cause each holder of more than 5% of its outstanding capital stock to execute substantially similar “lock up” agreements.  Neither the Company nor the underwriter shall terminate, materially amend or waive the enforcement of any material provision under a “lock up” agreement unless each “lock up” agreement with a Holder is also amended or waived in a similar manner or terminated, as the case may be.  The Company may impose stop-transfer instructions to enforce the restrictions imposed by this Section 2.4.

(b)      In connection with the filing of the Registration Statement by the Company pursuant to this Agreement, the Holders will furnish to the Company in writing such information as the Company reasonably requests for use in connection with such Registration Statement and the related prospectus and, to the fullest extent permitted by law, the Holders will indemnify and hold harmless the Company and its officers, directors, employees and agents, and each underwriter, if any, and any Person who controls such underwriter (within the meaning of Section 15 of the Securities Act), from and against any Losses, severally but not jointly, and any action in respect thereof to which the Company or its officers, directors, employees and agents, may become subject under the Securities Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) the purchase or sale of Registrable Securities during a suspension as set forth in Section 2.5(e) or Section 2.5(i) in each case after receipt of written notice of such suspension, (ii) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, prospectus or preliminary or summary prospectus or any amendment or supplement thereto, or (iii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but, with respect to clauses (ii) and (iii) above, only to the extent that such untrue statement or omission is made in such Registration Statement, any such prospectus or preliminary or summary prospectus or any amendment or supplement thereto, in reliance upon and in conformity with written information prepared and furnished to the Company by such Holder expressly for use therein or by failure of such Holder to deliver a copy of the Registration Statement or prospectus or any amendments or supplements thereto, and such Holder will reimburse the Company for any reasonable legal or any other expenses incurred by them in connection with investigating or defending or preparing to defend against any such Loss, action or proceeding; provided, however, that such Holder shall not be liable in any such case to the extent that prior to the filing of any such Registration Statement or prospectus or amendment or supplement thereto, such Holder has furnished in writing to the Company information expressly for use in such Registration Statement or prospectus or any amendment or supplement

12

thereto which corrected or made not misleading information previously furnished to the Company.  The obligation of each Holder to indemnify the Company and its officers, directors, employees and agents,  shall be limited to the net proceeds received by such Holder from the sale of Registrable Securities under such Registration Statement.  In no event, however, shall any Holder be liable for indirect, incidental or consequential or special damages of any kind.

(c)       Promptly after receipt by any Person in respect of which indemnity may be sought pursuant to Section 2.8(a) or 2.8(b) (an “Indemnified Party”) of notice of any claim or the commencement of any action, the Indemnified Party shall, if a claim in respect thereof is to be made against the Person against whom such indemnity may be sought (an “Indemnifying Party”), promptly notify the Indemnifying Party in writing of the claim or the commencement of such action; provided, that the failure to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to an Indemnified Party under Section 2.8(a) or 2.8(b) except to the extent of any actual prejudice resulting therefrom.  If any such claim or action shall be brought against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified Indemnifying Party, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the written opinion of counsel to such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest between them, it being understood, however, that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar or related claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for all Indemnified Parties.  No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding other than the payment of monetary damages by the Indemnifying Party on behalf of the Indemnified Party.  Whether or not the defense of any claim or action is assumed by the Indemnifying Party, such Indemnifying Party will not be subject to any liability for any settlement made without its written consent, which consent will not be unreasonably withheld.

(d)      If the indemnification provided for in this Section 2.8 is unavailable to the Indemnified Parties in respect of any Losses referred to herein notwithstanding that this Section 2.8 by its terms provides for indemnification in such case, then each Indemnifying Party,

13

in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Holders on the other from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company on the one hand and the Holders on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of each Holder on the other shall be determined by reference to, among other things, whether any action taken, including any 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 such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.8(d) 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 the immediately preceding paragraph.  The amount paid or payable by an Indemnified Party as a result of the Losses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 2.8, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Holder were offered to the public exceeds the amount of any Losses which such Holder has otherwise paid 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.  Each Holder’s obligations to contribute pursuant to this Section 2.8 is several in the proportion that the proceeds of the offering received by such Holder bears to the total proceeds of the offering received by all the Holders.  The indemnification provided by this Section 2.8 shall be a continuing right to indemnification with respect to sales of Registrable Securities and shall survive the registration and sale of any Registrable Securities by any Holder and the expiration or termination of this Agreement.  The indemnity and contribution agreements contained herein are in addition to any liability that any Indemnifying Party might have to any Indemnified Party.

2.9                                 Participation in Registrations.

(a)       No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and this Agreement.

(b)      Each Person that is participating in any registration under this Agreement agrees that, upon receipt of any notice from the Company of the happening of any event of the

14

kind described in Section 2.5(e) or Section 2.5(i) above, such Person will forthwith discontinue the disposition of its Registrable Securities pursuant to the Registration Statement and all use of the Registration Statement or any prospectus or related document until such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by such Section 2.5(e) or Section 2.5(i) and, if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of such documents at the time of receipt of such notice.  Furthermore, each Holder agrees that if such Holder uses a prospectus in connection with the offering and sale of any of the Registrable Securities, the Holder will use only the latest version of such prospectus provided by Company.

(c)       None of the Holders shall have the right to participate as a purchaser or otherwise acquire any beneficial ownership of the Company’s securities in any offering of the Company’s securities, including any shareholder rights offering (i) occurring within twelve (12) months from the date of this Agreement and (ii) in which any proceeds from such offering are used to directly or indirectly reduce the Company’s indebtedness incurred to finance the transactions contemplated by the Purchase Agreement.

2.10                           Compliance.  With respect to any registration under this Agreement, each Holder shall comply in all material respects with all applicable securities and other laws, rules and regulations, including but not limited to all rules and regulations of the SEC, the National Association of Securities Dealers and any securities exchange or quotation service on which the Company’s securities are listed or quoted.
