ARTICLE I

GOVERNANCE MATTERS

1.1 Board Representation. At the Second Effective Time, the Company will cause the Board Representative to be appointed to the Board of Directors of the Company (the “Board”), and thereafter, for so long as the Warburg Investor Beneficially Owns at least an amount of Company Common Stock (the “Qualifying Ownership Interest”) equal to the lesser of (a) 5% of all of the outstanding shares of Company Common Stock and (b) 50% of the number of Shares received by the Warburg Investor in the Mergers, will (i) at each annual or special meeting of the Company’s stockholders at which the class of directors to which the Board Representative has been appointed is to be elected to the Board, include the Board Representative in the slate of nominees recommended by the Board to the Company’s

stockholders for election as directors, (ii) use its reasonable best efforts to solicit proxies in order to obtain stockholder approval of the election of the Board Representative, including causing officers of the Company who hold proxies (unless otherwise directed by the Company stockholder submitting such proxy) to vote such proxies in favor of the election of such Board Representative, and (iii) use substantially the same efforts to cause the Board Representative to be elected to the Board as it uses to cause other nominees of the Board to be elected, including recommending that the Company’s stockholders vote in favor of the Board Representative in any proxy statement used by the Company to solicit the vote of its stockholders in connection with each annual or special meeting of the Company’s stockholders at which directors are to be elected to the Board. On the date that the Warburg Investor no longer Beneficially Owns a Qualifying Ownership Interest, the Warburg Investor will have no further rights under this Section 1.1 and Section 1.2 and, in each case at the written request of the Board, shall immediately cause its Board Representative to resign from the Board.

1.2 Replacement of Board Representative. Subject to Section 1.1 and 1.4, upon the death, resignation, retirement, disqualification or removal from office as a member of the Board of the Board Representative, the Warburg Investor shall have the right to designate the replacement. The Board shall use reasonable best efforts to take all action required to fill the vacancy resulting therefrom with such replacement designated by the Warburg Investor as promptly as practicable.

1.3 Compensation; Indemnification. The Board Representative shall be entitled to the same compensation, expense reimbursement and advancement, exculpation and indemnification in connection with his or her role as a director as the other members of the Board, as well as reimbursement for documented, reasonable out-of-pocket expenses incurred in attending meetings of the Board or any committee of the Board of which the Board Representative is a member, if any, in each case to the same extent as the other members of the Board. The Company will maintain directors and officers liability insurance policies for all directors in such amounts and on such terms as approved by the Board from time to time. To the extent that the Board Representative is entitled to be indemnified by the Company (in his capacity as Board Representative) or any insurer (the “Primary Insurer”) under this Section 1.3, by any other person pursuant to rights to which the Board Representative may be entitled by contract or as a matter of law or equity (a “Secondary Indemnitor”) and/or by any insurer under any other policy applicable to the Board Representative (a “Secondary Insurer”), (a) the obligations of the Company under this Section 1.3 shall be primary and the obligations of any such Secondary Indemnitor shall be secondary, and the Company shall not be entitled to contribution or indemnification from or subrogation against any such Secondary Indemnitor with respect to any of its obligations under this Section 1.3, and (b) the Company shall use commercially reasonable efforts to cause the obligations of the Primary Insurer under this Section 1.3 to be primary and the obligations of the Secondary Insurer to be secondary and use commercially reasonable efforts to cause the Primary Insurer to not be entitled to contribution or indemnification from or subrogation against any such Secondary Insurer with respect to any of its obligations under this Section 1.3. Notwithstanding the foregoing, the parties agree and acknowledge that under no circumstances will the Company be required to initiate any Action or incur any fees or expenses (other than diminis out of pocket fees and expenses) or take any action that could reasonably be expected to result in an increase in insurance premium, change in coverage or scope of insurance or the loss or denial of coverage.

1.4 Selection of Board Representative. For purposes of this Agreement, “Board Representative” means the person designated by the Warburg Investor to be elected or appointed to the Board, or his or her replacement designated in accordance with Section 1.2, which person must be determined to be qualified for service on the Board by the Company’s Nominating and Corporate Governance Committee (the “Governance Committee”), applying in good faith substantially similar standards of qualification to those it applies to other nominees for election to the Board. Without limitation to the foregoing, if the Governance Committee determines in good faith that a person designated by the Warburg Investor is not so qualified, it will notify the Warburg Investor in writing explaining the reasons therefor in reasonable detail and the Warburg Investor may designate one or more alternative persons to be elected or appointed to the Board until the Governance Committee accepts such person as Board Representative. The parties hereby agree that the initial Board Representative shall be Michael E. Martin, who is deemed qualified for service on the Board.

1.5 Notice; Information. So long as the Board Representative is a director, the Company shall notify, at the same time and in the same manner as such notification is delivered to the other members of the Board, (i) the Board Representative of all regular meetings and special meetings of the Board and (ii) the Board Representative of all regular and special meetings of any committee of the Board of which the Board Representative is a member. The Company and the Board shall provide the Board Representative with copies of all notices, minutes, consents and other material that it provides to all other members of the Board concurrently as such materials are provided to the other members.

1.6 Venture Capital Qualifying Investment. The Company hereby agrees that, subject to applicable Law and subject to VCOC Investor entering into a confidentiality agreement reasonably acceptable Purchaser, and at all times when the Warburg Investor holds a Qualifying Ownership Interest, it shall (i) provide the VCOC Investor reasonable access to the books and records of the Company and (ii) permit the VCOC Investor reasonable access to discuss the affairs, finances and accounts of the Company, and to make proposals and furnish advice with respect thereto, with the principal officers of the Company from time to time. The provisions of this Section 1.6 shall terminate on the earlier of (i) the date on which the Warburg Investor no longer holds a Qualifying Ownership Interest, and (ii) the date on which, in the VCOC Investor’s good faith judgment, the provisions of this Section 1.6 are no longer required in order for the ownership of the shares of Company Common Stock to qualify as a venture capital investment within the meaning of Department of Labor “plan asset” regulations. The Warburg Investor agrees to notify the Company promptly if, in the VCOC Investor’s good faith judgment, the provisions set forth in this Section 1.6 are no longer required in order for the ownership of the shares of Company Common Stock to qualify as a venture capital investment within the meaning of Department of Labor “plan asset” regulations (a “VCOC”).

ARTICLE III

REGISTRATION RIGHTS

3.1 Registration.

(a) Subject to the terms and conditions of this Agreement and the Company’s receipt of information from Investors that is required by applicable law to be included in such Shelf Registration Statement regarding such Investors, within two Business

-5-

Days after the Closing Date, the Company shall prepare and file with the SEC a Shelf Registration Statement covering all Registrable Securities (or otherwise designate an existing Shelf Registration Statement filed with the SEC to cover the Registrable Securities) and use reasonable best efforts to cause such Shelf Registration Statement to be declared effective as promptly as practicable (and in any event within 60 days following the Closing Date). The Company shall use reasonable best efforts to keep such Shelf Registration Statement continuously effective and in compliance with the Securities Act and usable for resale of such Registrable Securities for a period from the date of its initial effectiveness until such time as there are no Registrable Securities remaining (including by promptly refiling such Shelf Registration Statement (or a new Shelf Registration Statement) if the initial Shelf Registration Statement expires). If the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) at the time of filing of the Shelf Registration Statement with the SEC, such Shelf Registration Statement shall be designated by the Company as an automatic Shelf Registration Statement.

(b) Any registration pursuant to this Section 3.1 shall be effected by means of a shelf Registration Statement under the Securities Act (a “Shelf Registration Statement”) in accordance with the methods and distribution set forth in the Shelf Registration Statement and Rule 415. If an Investor or any other holder of Registrable Securities to whom the registration rights conferred by this Agreement have been transferred in compliance with this Agreement intends to distribute any Registrable Securities by means of an underwritten offering it shall promptly so advise the Company and the Company shall take all reasonable steps to facilitate such distribution, including the actions required pursuant to Section 3.3; provided that the Company shall not be required to facilitate an underwritten offering of Registrable Securities unless the expected gross proceeds from such offering exceed $35,000,000. The lead underwriters in any such distribution shall be selected by the holders of a majority of the Registrable Securities to be distributed; provided that such selections are reasonably acceptable to the Company.

(c) The Company shall not be required to effect a registration (including a resale of Registrable Securities from an effective Shelf Registration Statement) or an underwritten offering pursuant to this Section 3.1: (i) with respect to securities that are not Registrable Securities; (ii) during any Scheduled Black-out Period; or (iii) if the Company has notified the Investors and all other Holders that in the good faith judgment of the Board, it would be materially detrimental to the Company or its security holders for such registration or underwritten offering to be effected at such time, in which event the Company shall have the right to defer such registration or underwritten offering for a period of not more than 30 Business Days after receipt of the request of an Investor or any other Holder; provided that such right to delay a registration or underwritten offering shall be exercised by the Company (A) only if the Company has generally exercised (or is concurrently exercising) similar black-out rights against holders of similar securities that have registration rights and (B) not more than three times in any 12-month period and not more than 75 Business Days in the aggregate in any 12-month period.

(d) If, during a period when the Shelf Registration Statement is not effective or available, the Company proposes to file a Registration Statement with respect to an offering of its equity securities, other than a registration pursuant to Section 3.1(a) or a Special Registration, and the registration form to be filed may be used for the registration or qualification

-6-

for distribution of Registrable Securities, the Company will give prompt written notice to the Investors and all other Holders of its intention to effect such a registration (but in no event less than ten Business Days prior to the anticipated filing date) and (subject to clause (f) below) will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within five Business Days after the date of the Company’s notice (a “Piggyback Registration”). Any such person that has made such a written request may withdraw its Registrable Securities from such Piggyback Registration by giving written notice to the Company and the managing underwriter, if any, on or before the pricing date of such Piggyback Registration. The Company may terminate or withdraw any registration under this Section 3.1(d) prior to the effectiveness of such registration, whether or not the Investors or any other Holders have elected to include Registrable Securities in such registration. “Special Registration” means the registration of (i) equity securities and/or options or other rights in respect thereof solely registered on Form S-4 or Form S-8 (or successor form) or (ii) shares of equity securities and/or options or other rights in respect thereof to be offered to directors, members of management, employees, consultants, customers, lenders or vendors of the Company or its subsidiaries or in connection with dividend reinvestment plans.

(e) If the registration referred to in Section 3.1(d) is proposed to be underwritten, the Company will so advise each Investor and all other Holders as a part of the written notice given pursuant to Section 3.1(d). In such event, the right of any Investor and all other Holders to registration pursuant to this Section 3.1 will be conditioned upon such persons’ participation in such underwriting and the inclusion of such persons’ Registrable Securities in the underwriting, and each such person will (together with the Company and the other persons distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Any Holder so participating shall not be required to make any representations or warranties to or agreements with the Company or the underwriters in connection with such underwriting agreement other than representations, warranties or agreements regarding such Holder, such Holder’s title to the Registrable Securities, such Holder’s authority to sell the Registrable Securities, such Holder’s intended method of distribution, absence of liens with respect to the Registrable Securities, enforceability of the applicable underwriting agreement as against such Holder, receipt of all consents and approvals with respect to the entry into such underwriting agreement and the sale of such Registrable Securities by such Holder and any other representations required to be made by such Holder under applicable law, rule or regulation, and the aggregate amount of the liability of such Holder in connection with such underwriting agreement shall not exceed such Holder’s net proceeds from such underwritten offering (i.e., less underwriting discounts and commissions). If any participating person disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company and the managing underwriter prior to the effective date of such registration.

(f) If (x) the Company grants “piggyback” registration rights to one or more third parties to include their securities in an underwritten offering under the Shelf Registration Statement pursuant to Section 3.1(b) or (y) a Piggyback Registration under Section 3.1(d) relates to an underwritten primary offering on behalf of the Company, and in either case the managing underwriters advise the Company that in their reasonable opinion the number of securities requested to be included in such offering exceeds the number which can be sold without adversely affecting the marketability of such offering (including an adverse effect on the

-7-

per share offering price), the Company will include in such registration or prospectus only such number of securities that in the reasonable opinion of such underwriters can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, in the case of a Piggyback Registration under Section 3.1(d), the securities the Company proposes to sell, (ii) second, Registrable Securities of the Investors and all other Holders who have requested registration of Registrable Securities pursuant to Sections 3.1(b) or 3.1(d), as applicable, pro rata on the basis of the aggregate number of such securities or shares owned by each such person and (iii) third, any other securities of the Company that have been requested to be so included, subject to the terms of this Agreement.

3.2 Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification or compliance hereunder 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 aggregate offering or sale price of the securities so registered.

3.3 Obligations of the Company. The Company shall use its reasonable best efforts for so long as there are Registrable Securities outstanding, to take such actions as are under its control to remain a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) if it becomes eligible for such status in the future (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)). In addition, whenever required to effect the registration of any Registrable Securities or facilitate the distribution of Registrable Securities pursuant to an effective Shelf Registration Statement, the Company shall, as expeditiously as reasonably practicable:

(a) Prepare and file with the SEC a prospectus supplement with respect to a proposed offering of Registrable Securities pursuant to an effective Registration Statement, subject to this Section 3.3, keep such Registration Statement effective or such prospectus supplement current until the securities described therein are no longer Registrable Securities.

(c) Furnish to the Holders and any underwriters such number of copies of the applicable Registration Statement and each such amendment and supplement thereto (including in each case all exhibits) and 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 or to be distributed by them.

(d) Use its reasonable best efforts to register and qualify the securities covered by such Registration Statement under such other securities or blue sky laws of such

-8-

jurisdictions as shall be reasonably requested by the Holders or any managing underwriter(s), to keep such registration or qualification in effect for so long as such Registration Statement remains in effect, and to take any other action which may be reasonably necessary to enable such seller to consummate the disposition in such jurisdictions of the securities owned by such Holder; 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) Notify each Holder of Registrable Securities 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 applicable prospectus, 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 light of the circumstances then existing.

(f) Give written notice to the Holders:

(i) when any Registration Statement filed pursuant to Section 3.1 or any amendment thereto has been filed with the SEC (except for any amendment effected by the filing of a document with the SEC pursuant to the Exchange Act) and when such Registration Statement or any post-effective amendment thereto has become effective;

(ii) of any request by the SEC for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for that purpose;

(vi) if at any time the representations and warranties of the Company contained in any underwriting agreement contemplated by Section 3.3(j) cease to be true and correct.

(h) Upon the occurrence of any event contemplated by Section 3.3(e) or 3.3(f)(v), promptly prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus or file any other required document so that, as thereafter delivered to the Holders and any underwriters, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(i) Use reasonable best efforts to procure the cooperation of the Company’s transfer agent in settling any offering or sale of Registrable Securities.

(j) If an underwritten offering is requested pursuant to Section 3.1(b), enter into an underwriting agreement in customary form, scope and substance and take all such other actions reasonably requested by the Holders of a majority of the Registrable Securities being sold in connection therewith or by the managing underwriter(s), if any, to expedite or facilitate the underwritten disposition of such Registrable Securities, and in connection therewith in any underwritten offering (including making members of management and executives of the Company reasonably available to participate in “road shows,” similar sales events and other marketing activities), (i) make such representations and warranties to the Holders that are selling stockholders and the managing underwriter(s), if any, with respect to the business of the Company and its subsidiaries, and the Shelf Registration Statement, prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in customary form, substance and scope, and, if true, confirm the same if and when requested, (ii) use its reasonable best efforts to furnish the underwriters with opinions of counsel to the Company, addressed to the managing underwriter(s), if any, covering the matters customarily covered in such opinions requested in underwritten offerings, (iii) use its reasonable best efforts to obtain “cold comfort” letters from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any business acquired by the Company for which financial statements and financial data are included in the Shelf Registration Statement) who have certified the financial statements included in such Shelf Registration Statement, addressed to each of the managing underwriter(s), if any, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters, (iv) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures customary in underwritten offerings, and (v) deliver such documents and certificates as may be reasonably requested by the Holders of a majority of the Registrable Securities being sold in connection therewith, their counsel and the managing underwriter(s), if any, to evidence the continued validity of the representations and warranties made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company.

(a) The Company agrees to indemnify each Holder and, if a Holder is a person other than an individual, such Holder’s direct or indirect partners, members or stockholders and each of such partner’s, member’s or stockholder’s partners, members or stockholders and, with respect to all of the foregoing Persons, each of their respective Affiliates, employees, directors, officers, trustees or agents and controlling Persons within the meaning of the Securities Act and each of their respective representatives (each, an “Indemnitee”), against any and all Losses, joint or several, arising out of or based upon (i) any untrue statement or alleged untrue statement of material fact contained in any Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto or any documents incorporated therein by reference or contained in any free writing prospectus (as such term is defined in Rule 405) prepared by the Company or authorized by it in writing for use by such Holder (or any amendment or supplement thereto) or any omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, that the Company shall not be liable to such Indemnitee in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon (A) an untrue statement or omission made in such Registration Statement, including any such preliminary prospectus or final prospectus contained therein or any such amendments or supplements thereto or contained in any free writing prospectus (as such term is defined in Rule 405) prepared by the Company or authorized by it in writing for use by such Holder (or any amendment or supplement thereto), in reliance upon and in conformity with information regarding such Indemnitee or its plan of distribution or ownership interests which was furnished in writing to the Company by such Indemnitee expressly for use in connection with such Registration Statement, including any such preliminary prospectus or final prospectus contained therein or any such amendments or supplements thereto, or (B) offers or sales effected by or on behalf such Indemnitee “by means of” (as defined in Rule 159A) a “free writing prospectus” (as such term is defined in Rule 405) that was not authorized in writing by the Company; (ii) any violation or alleged violation by the Company of any federal, state or common law rule or regulation applicable to the Company or any of its subsidiaries in connection with any such registration, qualification, compliance or sale of Registrable Securities; (iii) any failure to register or qualify Registrable Securities in any state where the Company or its agents have affirmatively undertaken or agreed in writing that the Company (the undertaking of any underwriter being attributed to the Company) will undertake such registration or qualification on

-12-

behalf of the Holders of such Registrable Securities (provided that in such instance the Company shall not be so liable if it has undertaken its reasonable best efforts to so register or qualify such Registrable Securities); or (iv) any actions or inactions or proceedings in respect of the foregoing whether or not an Indemnitee is a party thereto, whether such Registration Statement, final prospectus, preliminary prospectus, free writing prospectus (as defined in Rule 405) or other document is issued pursuant to this Agreement or otherwise.

(b) In connection with any Registration Statement in which a Holder is participating, each such Holder shall, severally and not jointly, indemnify the Company, its directors and officers, and each Person, if any, who controls the Company within the meaning of the Securities Act to the same extent as the foregoing indemnity provided for in Section 3.7(a) from the Company to the Holders, but only to the extent arising out of or based upon information furnished in writing by such Holder, or on such Holder’s behalf, expressly for use in any Registration Statement or any prospectus, including any amendment or supplement thereto. In no event shall the liability of such Holder hereunder be greater in amount than the dollar amount of the net proceeds (less underwriting discounts and commissions) received by such Holder under the sale of Registrable Securities giving rise to such indemnification obligation.

(c) If the indemnification provided for in this Section 3.7 is unavailable to any Person for whom indemnity may be sought (the “Indemnified Party”) from the Person against whom such indemnity may be sought (the “Indemnifying Party”) with respect to any Losses or is insufficient to hold the Indemnified Party harmless as contemplated therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnified Party, on the one hand, and the Indemnifying Party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party, on the one hand, and of the Indemnified Party, on the other hand, shall be determined by reference to, among other factors, whether the untrue statement of a material fact or 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 Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 3.7(c) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 3.7. No Indemnified Party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Indemnifying Party if the Indemnifying Party was not guilty of such fraudulent misrepresentation.

3.8 Assignment of Registration Rights. The rights of the Investors to registration of Registrable Securities pursuant to Section 3.1 (but no other rights hereunder) may be assigned by the Investors to a transferee or assignee of Registrable Securities to which there is transferred to such transferee no less than $100,000,000 in Registrable Securities (with respect to transfers by the Management Blocker, such number shall be $5,000,000); provided, however, that the transferor shall, within ten days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the number and type of Registrable Securities that are being assigned.

-13-

3.9 Holdback. With respect to any underwritten offering of Registrable Securities by the Investors or other Holders pursuant to this Article III, the Company agrees not to effect (other than pursuant to such registration or pursuant to a Special Registration) any public sale or distribution, or to file any Registration Statement (other than such registration or a Special Registration) covering any of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the period not to exceed ten days prior and 60 days following the effective date of such offering or such longer period up to 90 days as may be requested by the managing underwriter. The Company agrees to cause each of its directors and senior executive officers to execute and deliver, and each Holder also agrees to execute and deliver, customary lockup agreements in such form and for such time period up to 90 days as may be requested by the managing underwriter; provided that each Holder shall not be required to execute and deliver any lockup agreement different in form or substance as any lockup executed by the Company’s directors and senior executive officers.

3.10 Rule 144; Rule 144A Reporting. With a view to making available to the Investors and 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 reasonable best efforts to:

(c) so long as an Investor or a Holder owns any Registrable Securities, furnish to such Investor or such Holder forthwith upon request: a written statement by the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act, and of the Exchange Act; a copy of the most recent annual or quarterly report of the Company; and such other reports and documents as the Investor or Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration; and

(d) take such further action as any Holder may reasonably request (including, without limitation (i) making its Chief Executive Officer and Chief Financial Officer reasonably available to potential purchasers in a reasonable manner (by telephone where feasible) and except during periods when the Company has restricted access to investors in accordance with its Regulation FD procedures and other policies and procedures required by applicable law; and (ii) executing a customary engagement letter that will provide for customary indemnification of a placement agent with respect to such placement), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act, and provided that the commission and fees for such placement shall be at the expense of the requesting Holder
