     (a) Requested Registration.

     (i) Request for Registration. If the Company shall receive from an Initiating Holder, at any time after the Effective Date, subject to Section (2)(j), if applicable, a written request that the Company effect any registration with respect to more than 30% of the Registrable Securities, the Company will:

     (1) promptly give written notice of the proposed registration, qualification or compliance to all other Holders; and

     (2) as soon as practicable, but in no event prior to the time permitted under the Initial Underwriting Agreement, use its diligent best 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 compliance with applicable regulations issued under the Securities Act) 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 joining in such request as are specified in a written request received by the Company within 10 business days after written notice from the Company is given under Section 2(a)(i)(1) above; provided that the Company shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Section 2(a):

(A) 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 or applicable rules or regulations thereunder;

(B) After the Company has effected two (2) such registrations pursuant to this Section 2(a) and such registrations have been declared or ordered effective and the sales of such Registrable Securities shall have closed;

(C) If the Registrable Securities requested by all Holders to be registered pursuant to such request do not have an anticipated aggregate public offering price (before any underwriting discounts and commissions) of not less than $5,000,000;

(D) During the period starting with the date forty-five (45) days prior to the Company’s good faith estimate of the date of filing of, and ending on the date ninety (90) days (or in the case of the offering contemplated by the

Initial Public Offering, such period of time as provided in the Initial Underwriting Agreement) immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities in a Rule 145 transaction, or a registration on any registration form (including Form S-4) which does not permit secondary sales, with respect to an employee benefit plan or with respect to the Company’s first registered public offering of its stock); provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective;

(E) If the Company shall furnish to the Initiating Holders a certificate signed by an officer of the Company stating that in the good faith judgment of the Board of Directors it would be significantly detrimental to the Company or its stockholders for a registration statement to be filed or securities to be offered, in which case the Company’s obligation to use its best efforts to comply with this Section 2 shall be deferred for a period not to exceed sixty (60) days from the date of receipt of written request from the Initiating Holders; provided, however, that the Company shall not exercise such right more than once in any twelve (12) month period.

     The registration statement filed pursuant to the request of the Initiating Holders may, subject to the provisions of Section 2(a)(ii) below, include other securities of the Company which are held by Persons who, by virtue of agreements with the Company, are entitled to include their securities in any such registration (“Other Stockholders”). In the event any Holder requests a registration pursuant to this Section 2(a) in connection with a distribution of Registrable Securities to its stockholders, partners, members or holders of other beneficial or equity interests, the registration shall provide for the resale by such Persons, if requested by such Holder.

     The registration rights set forth in this Section 2 may be assigned, in whole or in part, by an Initial Holder or any of its Affiliates to any transferee of Registrable Securities (who shall agree to be bound by all obligations of this Agreement), but may not be assigned, without the written consent of the Company in its sole discretion, by any person who is not an Initial Holder or any Affiliate of an Initial Holder.

       (ii) Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2(a).

     If Other Stockholders request such inclusion, the Holders shall offer to include the securities of such Other Stockholders in the underwriting and may condition such offer on their acceptance of the further applicable provisions of this Section 2. The Holders whose shares are to be included in such registration and the Company shall (together with all Other Stockholders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Initiating Holders and reasonably acceptable to the Company. Notwithstanding any other provision of this Section 2(a), if the representative advises the Holders in writing that marketing factors require a limitation on the number of shares to be

underwritten, the securities of the Company held by Other Stockholders shall be excluded from such registration to the extent so required by such limitation. If, after the exclusion of such shares, further reductions are still required, the number of shares included in the registration by each Holder shall be reduced on a pro rata basis (based on the number of shares held by such Holder), by such minimum number of shares as is necessary to comply with such request. No Registrable Securities or any other securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If any Other Stockholder who has requested inclusion in such registration as provided above disapproves of the terms of the underwriting, such Person may elect to withdraw therefrom by written notice to the Company, the underwriter and the Initiating Holders. The securities so withdrawn shall also be withdrawn from registration. If the underwriter has not limited the number of Registrable Securities or other securities to be underwritten, the Company and officers and directors of the Company may include its or their securities for its or their own account in such registration if the representative so agrees and if the number of Registrable Securities and other securities which would otherwise have been included in such registration and underwriting will not thereby be limited. If the Company includes shares to be sold by it in any Registration Statement requested pursuant to this Section 2(a), such Registration Statement shall be deemed to have been a registration under Section 2(b), unless the Holders of Registrable Securities are able to include in such Registration Statement all of the Registrable Securities initially requested for inclusion in such Registration Statement.

     (b) Company Registration.

     (i) If the Company shall determine to register any of its equity securities either for its own account or for the account of Other Stockholders, other than a registration relating solely to employee benefit plans, or a registration relating solely to a Commission Rule 145 transaction, or a registration on any registration form (including Form S-4) which does not permit secondary sales, the Company will:

     (1) promptly give to each of the Holders a written notice thereof (which shall include a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable blue sky or other state securities laws); and

     (2) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made by the Holders within fifteen (15) days after receipt of the written notice from the Company described in clause (i) above, except as set forth in Section 2(b)(ii) below. Such written request may specify all or a part of the Holders’ Registrable Securities. In the event any Holder requests inclusion in a registration pursuant to this Section 2(b) in connection with a distribution of Registrable Securities to its stockholders, partners, members or holders of other beneficial or equity interests the registration shall provide for the resale by such Persons, if requested by such Holder.

     (ii) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise each of the Holders as a part of the written notice given pursuant to Section 2(b)(i)(1). In such event, the right of each of the Holders to registration pursuant to this Section 2(b) shall be

conditioned upon such Holders’ participation in such underwriting and the inclusion of such Holders’ Registrable Securities in the underwriting to the extent provided herein. The Holders whose shares are to be included in such registration shall (together with the Company and the Other Stockholders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for underwriting by the Company. Notwithstanding any other provision of this Section 2(b), if the representative determines that marketing factors require a limitation on the number of shares to be underwritten, and the representative may (subject to the allocation priority set forth below) limit the number of Registrable Securities to be included in the registration and underwriting to not less than twenty five percent (25%) of the shares included therein (based on the number of shares). The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated in the following manner: The securities of the Company held by officers, directors and Other Stockholders of the Company (other than Registrable Securities and other than securities held by holders who by contractual right demanded such registration (“Demanding Holders”)) shall be excluded from such registration and underwriting to the extent required by such limitation, and, if a limitation on the number of shares is still required, the number of shares that may be included in the registration and underwriting by each of the Holders and Demanding Holders shall be reduced, on a pro rata basis (based on the number of shares held by such Holder), by such minimum number of shares as is necessary to comply with such limitation. If any of the Holders or any officer, director or Other Stockholder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the underwriter. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

     (c) Form S-3. The Company shall use its best efforts to qualify for registration on Form S-3 for secondary sales. After the Company has qualified for the use of Form S-3, the Initiating Holders shall have the right to request three (3) registrations on Form S-3 (such requests shall be in writing and shall state the number of shares of Registrable Securities to be disposed of and the intended method of disposition of shares by such holders), provided that the Company shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Section 2(c):

     (i) Unless the Holder or Holders requesting registration propose to dispose of shares of Registrable Securities having an aggregate price to the public (before deduction of Selling Expenses) of more than $5,000,000;

     (ii) Within ninety (90) days of the effective date of the most recent registration pursuant to this Section 2(c) in which securities held by the requesting Holder could have been included for sale or distribution;

     (iii) 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 or applicable rules or regulations thereunder;

     (iv) During the period starting with the date forty-five (45) days prior to the Company’s good faith estimate of the date of filing of, and ending on the date ninety (90) days immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities in a Rule 145 transaction, a registration on any registration form (including Form S-4) which does not permit secondary sales or with respect to an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; provided, however, that the Company may only delay an offering pursuant to this Section 2(c)(iv) for a period of not more than sixty (60) days, if a filing of any other registration statement is not made within that period and the Company may only exercise this right once in any twelve (12) month period; or

     (v) If the Company shall furnish to the Holders a certificate signed by an officer of the Company stating that in the good faith judgment of the Board of Directors it would be significantly detrimental to the Company or its stockholders for a registration statement to be filed in the near future, in which case the Company’s obligation to use its best efforts to comply with this Section 2(c) shall be deferred for a period not to exceed sixty (60) days from the date of receipt of written request from the Holders; provided, however, that the Company shall not exercise such right more than once in any twelve (12) month period.

     The Company shall give written notice to all Holders of the receipt of a request for registration pursuant to this Section 2(c) and shall provide a reasonable opportunity for other Holders to participate in the registration, provided that if the registration is for an underwritten offering, the terms of Section 2(a)(ii) shall apply to all participants in such offering. Subject to the foregoing, the Company will use its best efforts to effect promptly the registration of all shares of Registrable Securities on Form S-3 to the extent requested by the Holder or Holders thereof for purposes of disposition. In the event any Holder requests a registration pursuant to this Section 2(c) in connection with a distribution of Registrable Securities to its stockholders, partners, members or holders of other beneficial or equity interests, the registration shall provide for the resale by such Persons, if requested by such Holder.

     (d) Expenses of Registration. Subject to Section 2(e), all Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to this Section 2 shall be borne by the Company, and all Selling Expenses shall be borne by the Holders of the securities so registered pro rata on the basis of the number of their shares so registered

     (e) Withdrawal of Registration Statement. At any time before the registration statement requested under Section 2(a) or Section 2(c) covering Registrable Shares becomes effective, the Holders of a majority of such shares may request the Company to withdraw or not to file the registration statement. In that event, unless such request of withdrawal was caused by, or made in response to, (i) a material adverse effect or a similar event related to the business, properties, condition, or operations of the Company not known (without imputing the knowledge of any other Person to such holders) by the holders initiating such request at the time their request was made, or other material facts not known to such Holders at the time their request was made, or (ii) a material adverse change in the financial markets, the Holders shall be deemed to have used one of their registration rights under Section 2(a) or Section 2(c), as applicable; provided, however, that such withdrawn registration shall not count as requested registration

pursuant to Section 2(a) or Section 2(c) above if the Company shall have been reimbursed (pro rata by the Holders holding a majority of the Registrable Shares requested to be registered or in such other proportion as the requesting Holders may agree) for all out-of-pocket expenses incurred by the Company in connection with such withdrawn registration.

     (f) Registration Procedures. In the case of each registration effected by the Company pursuant to this Section 2, the Company will keep the Holders, as applicable, advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will:

     (i) keep such registration effective for a period of one hundred twenty (120) days or until the Holders (or in the case of a distribution to the stockholders, partners, members or holders of other beneficial or equity interests of such Holder, such Persons, as applicable, have completed the distribution described in the registration statement relating thereto, whichever first occurs; provided, however, that (A) such 120-day period shall be extended for a period of time equal to the period during which the Holders (or stockholders, partners, members or holders of other beneficial or equity interests of a Holder) as applicable, refrain from selling any securities included in such registration in accordance with provisions in Section 2(j) hereof; and (B) in the case of any registration of Registrable Securities on Form S-3 which are intended to be offered on a continuous or delayed basis, such 120-day period shall be extended until all such Registrable Securities are sold, provided that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment which (y) includes any prospectus required by Section 10(a) of the Securities Act or (z) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference of information required to be included in (y) and (z) above to be contained in periodic reports filed pursuant to Section 12 or 15(d) of the Exchange Act in the registration statement;

     (ii) furnish such number of prospectuses and other documents incident thereto as each of the Holders, as applicable, from time to time may reasonably request;

     (iii) notify each Holder of Registrable Securities covered by such registration 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; and

     (iv) if such securities are being sold through underwriters, furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, (1) 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 and reasonably satisfactory to a majority in interest of the Holders participating in such registration, addressed to the underwriters, if any, and to the Holders participating in such registration and (2) 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 and reasonably satisfactory to a majority in interest of the Holders participating in such registration, addressed to the underwriters, if any, and if permitted by applicable accounting standards, to the Holders participating in such registration.

     (v) Otherwise use its diligent best efforts to comply with all applicable rules and regulations of the SEC, and make available to the Holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months, but not more than eighteen (18) months, beginning with the first month after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

     (g) Indemnification.

     (i) The Company will indemnify each of the Holders, as applicable, each of its officers, directors, members and partners, and each Person controlling each of the Holders, with respect to each registration which has been effected pursuant to this Section 2, and each underwriter, if any, and each person who controls any underwriter, 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 prospectus, offering circular or other document (including any related registration statement, notification or the like) 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 not misleading, or any violation by the Company of the Securities Act or the Exchange Act or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each of the Holders, each of its officers, directors, members and partners, and each Person controlling each of the Holders, each such underwriter and each Person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action, provided 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 based upon written information furnished to the Company by the Holders or underwriter and stated to be specifically for use therein.

     (ii) Each of the Holders will, if Registrable Securities held by it 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 and each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter, each Other Stockholder and each of their officers, directors, members and partners, and each person controlling such Other Stockholder 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 made by such Holder,

or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements by such Holder therein not misleading, and will reimburse the Company and such Other Stockholders, directors, officers, members, partners, persons, underwriters or control persons for any legal or any other expenses reasonably 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 such Holder and stated to be specifically for use therein; provided, however, that the obligations of each of the Holders hereunder shall be limited to an amount equal to the net proceeds to such Holder of securities sold as contemplated herein.

     (iii) Each party entitled to indemnification under this Section 2(g) (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 that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such party’s expense (unless the Indemnified Party shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the fees and expenses of counsel shall be at the expense of the Indemnifying Party), and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2 unless the Indemnifying Party is materially prejudiced thereby. No Indemnifying Party shall be liable for any settlement of any action or proceeding effected without its written consent. 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 which 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. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

     (iv) If the indemnification provided for in this Section 2(g) is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense 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 statements or omissions which resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things,

whether the untrue (or alleged untrue) statement of a material fact or the omission (or alleged omission) to state a material fact 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.

     (v) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with any underwritten public offering contemplated by this Agreement are in conflict with the foregoing provisions, the provisions in such underwriting agreement shall be controlling.

     (h) Information by the Holders.

     (i) Each of the Holders holding securities included in any registration shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Section 2.

     (ii) In the event that, either immediately prior to or subsequent to the effectiveness of any registration statement, any Holder shall distribute Registrable Securities to its stockholders, partners, members or holders of other beneficial or equity interests, such Holder shall so advise the Company and provide such information as shall be necessary to permit an amendment to such registration statement to provide information with respect to such Persons, as selling securityholders. Promptly following receipt of such information, the Company shall file an appropriate amendment to such registration statement reflecting the information so provided.

     (i) Rule 144 Reporting.

     With a view to making available the benefits of certain rules and regulations of the Commission which may permit the sale of restricted securities to the public without registration, the Company agrees to:

     (i) make and keep public information available as those terms are understood and defined in Rule 144 under the Securities Act (“Rule 144”), at all times from and after ninety (90) days following the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public;

     (ii) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at any time after it has become subject to such reporting requirements; and

     (iii) so long as the Holder owns any Registrable Securities, furnish to the Holder upon request, a written statement by the Company as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as the Holder may reasonably request in availing itself of any rule or

regulation of the Commission allowing the Holder to sell any such securities without registration.

     (j) “Market Stand-off” Agreement. Each of the Holders agrees, if requested by the Company or an underwriter of equity securities of the Company, not to sell or otherwise transfer or dispose of any Registrable Securities held by such Holder during the ninety (90) day period following the effective date of a registration statement of the Company filed under the Securities Act, provided that all officers and directors of the Company enter into similar agreements.

     If requested by the underwriters, the Holders shall execute a separate agreement to the foregoing effect. The Company may impose stop-transfer instructions with respect to the shares (or securities) subject to the foregoing restriction until the end of said ninety (90) day period. The provisions of this Section 2(j) shall be binding upon any transferee who acquires Registrable Securities. The parties understand and agree that the Holders have entered into separate agreements with the Initial Underwriters in respect of the offering contemplated by the Initial Registration Statement, which agreements, in respect of such offering, shall be deemed to have satisfied and be in lieu of the agreements set forth in or contemplated by this Section 2(j).
