The Company and all Holders proposing to distribute their securities in the underwritten registration shall, upon request by the managing underwriter selected for such underwriting by the Initiating Holders which managing underwriter shall be reasonably acceptable to the Company), enter into an underwriting agreement in customary form with to managing underwriter in connection with the offering. Notwithstanding any other provision of this Section 1.2, if the managing underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders who have requested to participate in such offering, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all such Holders thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities requested by such Holders to be included in such registration in the priority listed below, up to the aggregate maximum number of shares that, in the view of such managing underwriter, can be included: (i) first, all Registrable Securities requested to be registered by any Holders; and (ii) second, any Common Stock proposed to be registered by the Company and any Common Stock proposed to be registered by other holders.

The Registrable Securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to ninety (90) days after the effective date of such registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion and manner used in determining the underwriter limitation in this Section 1.2(b).

1.3 Company Registration.

(a) Piggy-Back Registration Rights. On each occasion, if any, following the date hereof that the Company contemplates filing with the Commission a registration statement under the Securities Act relating to the sale of shares of Common Stock other than (i) a registration relating solely to employee benefit plans; or (ii) a registration relating solely to a Commission Rule 145 transaction, the Company shall so notify the Holders in writing of its intention to do so at least thirty (30) days prior to the filing of each such registration statement; provided, however, that if the managing underwriter determines pursuant to Section 1.3(b) to

4

exclude all Registrable Securities from such registration, the Company need only so notify Holders within ten (10) days following the filing of such registration. Each Holder that gives written notice to the Company, within fifteen (15) days of receipt of such notice from the Company, of such Holder’s desire to have any of its Registrable Securities included in such registration statement, may, subject to the provisions of this Section 1.3, have its Registrable Securities so included.

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 1.3(a). In such event, the right of any Holder to registration pursuant a Section 1.3 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company.

If any Holder disapproves of the terms of any such underwriting, such party may elect to withdraw therefrom by written notice to the Company and the managing underwriter.

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by the Company under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

1.4 Registration on Form S-3.

(a) If any Holder requests that the Company file a registration Statement on Form S-3 (or any successor form to Form S-3) for an underwritten public offering of shares of the Registrable Securities the anticipated aggregate offering price of which is not less than $1,000,000, and the Company is a registrant entitled to use Form S-3 to register the Registrable Securities for such an offering, the Company shall use its reasonably commercial efforts to cause such Registrable Securities to be registered in such underwritten offering on such form; provided, however, that the Company shall not be required to effect more than one such registration pursuant to this Section 1.4 in any six-month period. The Company will (i) promptly give written notice of the proposed registration to all other Holders (and to any other holders if such registration is to relate in part to the primary offer and sale of shares of the Common Stock); and (ii) as soon as practicable, use its reasonably commercial efforts to effect such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate

5

compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders (or, if the registration is to relate in part to the primary offer and sale of shares of Common Stock, of any other holder) joining in such request as are specified in a written request received by the Company within fifteen (15) days after receipt of such written notice from the Company. The substantive provisions of Section 1.2(b) shall be applicable to each registration initiated under this Section 1.4.

(b) Notwithstanding the foregoing, the Company shall not be obligated to take any action pursuant to this Section 1.4: (i) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; (ii) during the ninety (90) days immediately following the effective date of the registration statement pertaining to the initial public offering of securities of the Company; or (iii) if (a) an investment banking firm of recognized national standing shall advise the Company and the Holders in writing that effecting the registration would materially and adversely affect an offering of the securities of the Company the preparation of which has the been commenced; or (b) the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company believes would not be in the best interest of the Company, provided that the Company’s obligation to use to commercially reasonable efforts to register, qualify or comply under this Section 1.2 shall be deferred for a period not to exceed ninety (90) days, and provided, further, that the Company shall not exercise its right under this clause to defer such obligation more than once in any twelve (12) month period.

1.5 Expenses of Registration.

(a) All Registration Expenses incurred in connection with (i) one registration pursuant to Section 1.2; (ii) all registrations pursuant to Section 1.3; and (iii) one registration pursuant to Section 1.4, shall be borne by the Company. The Company shall not be required to pay the Registration Expenses of any registration proceeding begun pursuant to Section 1.2, the request of which has been subsequently withdrawn by the Initiating Holders. Notwithstanding the foregoing, if prior to such withdrawal the Holders have learned of a material adverse change in the condition, business or prospects of the Company from that known to the Holders at the time of their request, of which the Company had knowledge at the time of the request, then the Holders shall not be required to pay any of said Registration Expenses or to forfeit the right to one demand registration.

(b) All Selling Expenses incurred in connection with any registration hereunder shall be borne pro-rata by the Holders (and, if applicable, any other holders) participating in such registration according to the number of Registrable Securities sold by such participating Holder (or, if applicable, any other holder) in such registration.

(c) Notwithstanding the provisions of Section 1.5(a), if, as a condition of registration or qualification of any offering in any state or jurisdiction in which the Company or

6

any underwriter determines in good faith that it wishes to offer securities registered in an offering to which this Agreement applies, it is required that offering expenses be allocated in a manner different from that provided in Section 1.5(a), the offering expenses shall be allocated in whatever permitted manner is most nearly in compliance with the provisions of this Agreement, so long as such allocation does not materially reduce the net proceeds received by any Holder.

1.6 Indemnification.

(a) To the extent permitted by law, the Company will indemnify each Holder, each of its officers and directors and partners, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Agreement, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation (or alleged violation) by the Company of the Securities Act or any rule or regulation promulgated under the Securities Act applicable to the Company in connection with any such registration, qualification or compliance, and the Company will reimburse or pay for the account of each such Holder, each of its officers and directors, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred (as and when incurred) in connection with investigating, preparing or defending any such claim, loss, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder, controlling person or underwriter and stated to be specifically for use therein.

(b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, each of its officers and directors and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse or pay for the account of the Company, such Holders, such directors, officers, persons, underwriters or control persons for any

7

legal or any other expenses reasonably incurred (as and when incurred) in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and stated to be specifically for use therein; provided, however, that the liability of a Holder for indemnification under this Section 1.6(b) shall not exceed the net proceeds from the offering received by such Holder, unless such liability arises out of or is based on willful misconduct of such Holder.

(c) Each party entitled to indemnification under this Section 1.6 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, further, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (which approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party’s expense; provided, however, that an Indemnified Party shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that 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. No Indemnifying Party shall be liable for indemnification hereunder with respect to any settlement or consent to judgment in connection with any claim or litigation to which these indemnification provisions apply, that has been entered into without the prior consent of the Indemnifying Party (which consent will not be unreasonably withheld).

(d) If the indemnification provided for in this Section 1.6 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 hereunder, 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 Parry on do one hand and of the Indemnified Party on the other in connection with the untrue statement (or alleged untrue statement) or omission (or alleged omission) 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

8

information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. Each Holder’s obligation to contribute pursuant to this Section 1.6 is several and not joint.

(d) Take such action, including the voluntary registration of its Common Stock under Section 12 of the Exchange Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective.

1.10 Transfer of Registration Rights. The rights to cause the Company to register securities granted to Holders under Sections 1.2, 1.3, and 1.4 may be assigned or otherwise conveyed to a transferee or assignee in connection with any transfer or assignment of Registrable Securities by a Holder (together with any affiliate) provided that: (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) the transferee shall agree to be bound by all of the provisions of this Agreement; (iii) such transfer does not violate any agreements by and among the Company and such Holders; and (iv) such transferee or assignee (a) is a wholly owned subsidiary, constituent partner (including retired and limited partners) or affiliate of such Holder, (b) is any family member of any individual Holder, (c) is a trust for the

Notwithstanding the foregoing, no transfer shall be effective hereunder unless the Company is given written notice by such transferee at the time of said transfer stating the name and address of said transferee, setting forth the facts underlying said transferee’s compliance with this Section 1.10, and setting forth said transferees agreement to be bound by this Agreement and the Right of First Refusal Agreement.
