(d)    The Company shall be obligated to reissue promptly unlegended certificates at the request of any Holder thereof if the Company has completed its Initial Offering and the Holder shall have obtained an opinion of counsel (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification and legend.

(e)    Any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal.

2.2    Demand Registration.

(a)    Subject to the conditions of this Section 2.2, if the Company shall receive a written request from any of the GA Holder, the Benchmark Holder or the Housatonic Holder as a group, acting through its designee (such requesting Holder, the “Initiating Holder”) that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities (a “Demand Registration”) with an anticipated aggregate offering price, net of underwriting discounts and commissions, of at least $10,000,000 (a “Qualified Public Offering”), then the Company shall, within thirty (30) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 2.2, effect, as expeditiously as reasonably possible, the registration under the Securities Act of all Registrable Securities that all Holders request to be registered.

(b)    If the Initiating Holder intends to distribute the Registrable Securities covered by its request by means of an underwriting, it shall so advise the Company as a part of its request made pursuant to this Section 2.2 and the Company shall include such information in the written notice referred to in Section 2.2(a). In such event, the right of any Holder to include its Registrable Securities in such registration 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 securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Initiating Holder (which underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 2.2, if the underwriter advises the Company that the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the success of such offering, then the Company shall include in such

-4-

registration only the aggregate amount of Registrable Securities that the underwriter believes may be sold without any such material adverse effect and shall reduce the amount of Registrable Securities to be included in such registration, first as to the Company, second as to the Holders (including the Initiating Holder) who requested to participate in such registration (as a group, if applicable), pro rata within each group based on the number of Registrable Securities owned by each such Holder. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members, retired members and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing Persons or the Affiliates of such Holder shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence.

(c)    The Company shall not be required to effect a registration pursuant to this Section 2.2 for any Holder:

(i)    prior to the earlier of (A) the third anniversary of the date of this Agreement or (B) of the expiration of the restrictions on transfer set forth in Section 2.10 following the Initial Offering;

(ii)    for each of the GA Holder, the Benchmark Holder and the Housatonic Holder, after the Company has effected two (2) registrations for such Initiating Holder pursuant to this Section 2.2, and such registrations have been declared or ordered effective and remain continuously effective for the lesser of (i) the period during which all Registrable Securities registered in such registration are sold and (ii) 120 days; provided, that (x) after such registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder has not been interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason not attributable to the Initiating Holder and such interference is not thereafter eliminated and (y) the conditions specified in the underwriting agreement, if any, entered into in connection with such registration are satisfied or waived, unless any failure of such conditions to be satisfied or waived is by reason of a failure by the Initiating Holder.

(iii)    during the period starting with the date of filing of, and ending on the date one hundred eighty (180) days following the effective date of the registration statement pertaining to a public offering, other than pursuant to a Special Registration Statement; provided that the Company makes reasonable good faith efforts to cause such registration statement to become effective;

(iv)    if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 2.2 a certificate signed by the Chairman of the Board stating that (i) in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration statement to be effected at such time or (ii) the Company intends to file a registration statement for a public offering within ninety (90) days other than pursuant to a Special Registration Statement, then the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the

-5-

request of the Initiating Holder; provided that the Company’s right to delay either a Demand Registration under this Section 2.2(c)(iv), a S-3 Registration under Section 2.4(c)(iv) or to institute a Suspension Period under Section 2.6(a) shall be exercised not more than once in any twelve (12) month period and in the aggregate shall not be in effect for more than ninety (90) days in any three hundred and sixty five (365) day period; or

(v)    in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance.

2.3    Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least twenty (20) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding Special Registration Statements) and will afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall, within fifteen (15) days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of disposition of the Registrable Securities by such Holder. 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 its securities, all upon the terms and conditions set forth herein.

(a)    Underwriting. If the registration statement of which the Company gives notice under this Section 2.3 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 include Registrable Securities in a registration pursuant to this Section 2.3 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. Notwithstanding any other provision of this Agreement, if the underwriter advises the Company that the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the success of such offering, then the Company shall include in such registration only the aggregate amount of Registrable Securities that the underwriter believes may be sold without any such material adverse effect and shall allocate the amount of Registrable Securities to be included in such registration, first, to the Company; second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by the Holders; and third, to any stockholder of the Company (other than a Holder) on a pro rata basis. 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 underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners,

-6-

members, retired members and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing Persons or the Affiliates of such Holder shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence.

(b)    Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.3 whether or not any Holder has elected to include securities in such registration, and shall promptly notify any Holder that has elected to include shares in such registration of such termination or withdrawal. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.5 hereof.

2.4    Form S-3 Registration.

(a)    If the Company shall receive a written request from any of the Holders that the Company effect a registration on Form S-3 (or any successor to Form S-3) or any similar short-form registration statement (an “S-3 Registration”) and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will (i) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders of Registrable Securities and (ii) as expeditiously as possible, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company.

(b)    Underwriting. If the Holders holding a majority of the Registrable Securities to be included in such S-3 Registration so elects, the Company shall use its best efforts to cause such S-3 Registration to be in the form of a firm commitment underwritten offering and the managing underwriter or underwriters shall be selected for such offering by the Holders holding a majority of the Registrable Securities to be included in such S-3 Registration (which underwriter or underwriters shall be reasonably acceptable to the Company). All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with such underwriter. If the underwriter believes that the registration of all or part of the Registrable Securities which the Holders have requested to be included would materially adversely affect the success of such public offering, then the Company shall be required to include in the underwritten offering, to the extent of the amount that the underwriter believes may be sold without causing such adverse effect, first, all of the Registrable Securities to be offered for the account of the Holders, pro rata based on the number of Registrable Securities owned by such Holders; second, any other securities requested to be included in such offering. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members, retired members and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing Persons or the Affiliates of such Holder shall be deemed to be a single “Holder,” and any pro rata reduction

-7-

with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence.

(c)    The Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.4:

(i)    if Form S-3 is not available for such offering by the Holders, or

(ii)    if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such S-3 Registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than five million dollars ($5,000,000), or

(iii)    if the Company shall furnish to the Holders a certificate signed by the Chairman of the Board of Directors of the Company stating that (i) in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such S-3 Registration to be effected at such time or (ii) the Company intends to file a registration statement for a public offering within ninety (90) days other than pursuant to a Special Registration Statement, then the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 2.4; provided that the Company’s right to delay either a Demand Registration under Section 2.2(c)(iv), a S-3 Registration under this Section 2.4(c)(iv) or to institute a Suspension Period under Section 2.6(a) shall be exercised not more than once in any twelve (12) month period and in the aggregate shall not be in effect for more than ninety (90) days in any three hundred and sixty five (365) day period, or

(iv)    if the Company has, within the twelve (12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 for the Holders pursuant to this Section 2.4, or

(v)    in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance.

(d)    Subject to the foregoing, the Company shall file a Form S-3 registration statement covering the Registrable Securities and other securities so requested to be registered as expeditiously as possible after receipt of the requests of the Holders. No S-3 Registration pursuant to this Section 2.4 shall be deemed or counted as a Demand Registration pursuant to Section 2.2.

2.5    Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to Section 2.2, 2.3 or 2.4 herein shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the Holders of the securities so registered pro rata on the basis of the number of shares so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to

-8-

Section 2.2 or 2.4, the request of which has been subsequently withdrawn by the Initiating Holder, with respect to a registration pursuant to Section 2.2, or the Holders of a majority of Registrable Securities to be registered thereunder, with respect to a registration pursuant to Section 2.4 unless (a) the withdrawal is based upon material adverse information concerning the Company’s finances of which the Holders were not aware at the time of such request or (b) the Initiating Holder, with respect to a registration pursuant to Section 2.2, or the Holders of a majority of Registrable Securities to be registered thereunder, with respect to a registration pursuant to Section 2.4 agree to deem such registration to have been effected as of the date of such withdrawal for purposes of determining whether the Company shall be obligated pursuant to Section 2.2(c)(ii) or 2.4(c)(iv), as applicable, to undertake any subsequent registration, in which event such right shall be forfeited by all Holders). If the Holders are required to pay the Registration Expenses, such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is required to pay the Registration Expenses of a withdrawn offering pursuant to clause (a) above, then such registration shall not be deemed to have been effected for purposes of determining whether the Company shall be obligated pursuant to Section 2.2(c)(ii) or 2.4(c)(iv), as applicable, to undertake any subsequent registration.

2.6    Obligations of the Company. Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(a)    prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to one hundred and twenty (120) days, or if earlier, until the Holder or Holders have completed the distribution related thereto or, if such Registrable Securities are offered on a continuous basis pursuant to Rule 415 under the Securities Act, until all Registrable Securities covered by such registration statement have been sold; provided, however, that at any time, upon written notice to the participating Holders and for a period not to exceed sixty (60) days thereafter (the “Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and the Initiating Holder hereby agrees not to offer or sell any Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes that there is or may be in existence material nonpublic information or events involving the Company, the failure of which to be disclosed in the prospectus included in the registration statement could result in a Violation (as defined below); provided, further that the Company’s right to delay either a Demand Registration under Section 2.2(c)(iv), a S-3 Registration under Section 2.4(c)(iv) or to institute a Suspension Period under this Section 2.6(a) shall be exercised not more than once in any twelve (12) month period and in the aggregate shall not be in effect for more than ninety (90) days in any three hundred and sixty five (365) day period. In the event that the Company shall exercise its right to delay or suspend the filing or effectiveness of a registration hereunder, the applicable time period during which the registration statement is to remain effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive sixty (60) days with the consent of the Holders holding a majority of the Registrable Securities registered under the applicable registration statement, which consent may be granted or withheld in such Holders’ sole discretion. If

-9-

so directed by the Company, all Holders registering shares under such registration statement shall (i) not offer to sell any Registrable Securities pursuant to the registration statement during the period in which the delay or suspension is in effect after receiving notice of such delay or suspension; and (ii) use their best efforts to deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holders’ possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. Notwithstanding the foregoing, the Company shall not be required to file, cause to become effective or maintain the effectiveness of any registration statement other than a registration statement on Form S-3 that contemplates a distribution of securities on a delayed or continuous basis pursuant to Rule 415 under the Securities Act.

(b)    Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above.

(c)    Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them.

(d)    Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions.

(e)    In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering and take such other actions as are prudent and reasonably required in order to expedite or facilitate the disposition of such Registrable Securities, including causing its officers to participate in “road shows” and other information meetings organized by the managing underwriter(s). Each Holder participating in such underwriting shall also enter into and perform its obligations under such underwriting agreement.

(f)    Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use best efforts to amend or supplement such prospectus in order to cause such prospectus not to include any 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 light of the circumstances then existing.

-10-

(g)    Use its best efforts to furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a letter, dated as of such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed to the underwriters.

2.7    Delay of Registration; Furnishing Information.

(a)    No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2.

(b)    It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities.

(c)    The Company shall have no obligation with respect to any registration requested pursuant to Section 2.2 or Section 2.4 if the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate offering price required to originally trigger the Company’s obligation to initiate such registration as specified in Section 2.2 or Section 2.4, whichever is applicable.

2.8    Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2, 2.3 or 2.4:

(a)    The Company will indemnify and hold harmless each Holder, the partners, members, officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading , or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement; and the Company will

reimburse each such Holder, partner, member, officer, director, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided however, that the Company shall not be liable to any Holder in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder.

(b)    Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following statements: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading (collectively, a “Holder Violation”), in each case to the extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that in no event shall any indemnity under this Section 2.8 exceed the net proceeds (after deducting the underwriters’ discounts and commissions) from the offering received by such Holder.

(c)    Any Person entitled to indemnification hereunder (the “Indemnified Party”) agrees to give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that the failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder (except to the extent that the Indemnifying Party is materially prejudiced or otherwise forfeits substantive rights or defenses by reason of such failure). If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party.

-12-

The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel reasonably satisfactory to the Indemnified Party or (iii) the named parties to any such action (including any impleaded parties) include both the Indemnifying Party and the indemnified Party and such parties have been advised by such counsel that either (x) representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct or (y) there may be one or more legal defenses available to the Indemnified Party which are different from or additional to those available to the Indemnifying Party. In any of such cases, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party, it being understood, however, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Indemnified Parties. No Indemnifying Party shall be liable for any settlement entered into without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the consent of such Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is a party and indemnity has been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability for claims that are the subject matter of such proceeding.

(d)    If the indemnification provided for in this Section 2.8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by, reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the Violation(s) or Holder Violation(s) referred to above shall be deemed to include, subject to the limitations set forth in this Section 2.8, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds (after deducting the underwriters’ discounts and commissions) from the offering received by such Holder.

(e)    The parties hereto agree that it would not be just and equitable if contribution pursuant to 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 Section 2.8(d). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the

-13-

Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(f)    The obligations of the Company and Holders under this Section 2.8 shall survive completion of any offering of Registrable Securities in a registration statement and, with respect to liability arising from an offering to which this Section 2.8 would apply that is covered by a registration filed before termination of this Agreement, such termination.

2.9    Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned by a Holder to a transferee or assignee of Registrable Securities (for so long as such shares remain Registrable Securities); provided, however, (i) the transferor shall, within ten (10) business days after such transfer, furnish to the Company 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, (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement and (iii) after giving effect to such transfer, such transferee shall own not less than one percent (1%) of the equity securities of the Company on a fully diluted basis.

2.10    “Market Stand-Off” Agreement. Each Holder hereby agrees that such Holder shall not sell, transfer, make any short sale of grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by such Holder (other than those included in the registration) during the 180-day period following the effective date of the Initial Offering (or such longer period, not to exceed 18 days after the expiration of the 180-day period, as the underwriters or the Company shall request in order to facilitate compliance with NASD Rule 2711); provided, that all officers and directors of the Company are bound by and have entered into similar agreements. The obligations described in this Section 2.11 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. No Holder of Registrable Securities subject to this Section 2.10 shall be released from any obligation under any agreement, arrangement or understanding entered into pursuant to this Section 2.10 unless all other Holders of Registrable Securities subject to the same obligation are also released.

2.11    Agreement to Furnish Information. Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s obligations under Section 2.11 or that are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 2.11 shall not apply to a Special Registration Statement. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said day period. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by Sections 2.11 and 2.12. The underwriters of the Company’s

-14-

stock are intended third party beneficiaries of Sections 2.11 and 2.12 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

2.12    Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to:

(a)    Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public;

(b)    File with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and

(c)    So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly report of the Company filed with the Commission; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration.

2.13    IPO Entity. If in lieu of a conversion to a corporation, the Company establishes a separate corporation that is a member of the Company or a subsidiary of the Company (the “IPO Entity”), whose shares are to be sold in the Initial Offering pursuant to an effective registration statement, all references in this Agreement to the Company shall, where appropriate, be deemed to refer to the IPO Entity. In such an event, the Company hereby agrees to cause the IPO Entity to comply with the provisions of this Agreement.

2.14    Registrable Securities. For the purposes of this Agreement, Registrable Securities held by a Holder will cease to be Registrable Securities for such Holder, when (i) a registration statement covering such Registrable Securities has been declared effective under the Securities Act by the Commission and such Registrable Securities have been disposed of pursuant to such effective registration statement or (ii) (x) the entire amount of the Registrable Securities owned by such Holder may be sold in a single sale, in the opinion of counsel satisfactory to the Company and such Holder, each in their reasonable judgment, without any limitation as to volume pursuant to Rule 144 (or any successor provision then in effect) under the Securities Act and (y) such Holder owns less than one percent (1%) the equity securities of the Company on a fully diluted basis.

SECTION 3.    INFORMATION RIGHTS.

3.1    Information Rights. The Company will furnish the GA Holder, the Benchmark Holder and the Housatonic Holder as soon as practicable:

Such financial statements shall be accompanied by a report and opinion thereon by independent public accountants selected by the Company’s Board of Directors;

It is further agreed that any waiver, permit, consent, or approval of any kind or character on any party’s part of any breach, default or noncompliance under the Agreement or any waiver on such party’s part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.
