THE HOLDER OF THESE SHARES, BY ACCEPTANCE OF THIS CERTIFICATE OR CONFIRMATION, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF THE AFORESAID AGREEMENT.”

2.3 Subsequent Sales. After expiration of the Restriction Period, Kennedy may sell the Registrable Securities (a) pursuant to the provisions of SEC Rule 144 (including the volume limitations imposed by SEC Rule 144, whether or not Kennedy is an affiliate of the Company at such time for purposes of Rule 144, or (b) pursuant to a registration statement in accordance with the provisions of Section 3 hereof.

4

2.4 Insider Trading Policy. At any time that Kennedy is an employee or director of the Company or otherwise in possession of material nonpublic information with respect to the Company, he will comply with any applicable insider trading policy of the Company and all applicable laws and regulations with respect to the sale of any Shares.

2.5 Notice of Sale; Compliance with Law. After the expiration of the Restriction Period, before any proposed sale, pledge, or transfer of any Escrow Shares or Registrable Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transaction, Kennedy shall give notice to the Company of his intention to effect such sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the proposed sale, pledge, or transfer in sufficient detail and, if reasonably requested by the Company, shall be accompanied at Kennedy’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall, be reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transaction may be effected without registration under the Securities Act; or (ii) any other evidence reasonably satisfactory to counsel to the Company to the effect that the proposed sale, pledge, or transfer of the Registrable Securities may be effected without registration under the Securities Act, whereupon Kennedy shall be entitled to sell, pledge, or transfer such Registrable Securities in accordance with the terms of the notice given by Kennedy to the Company. The Company will not require such a legal opinion in any transaction in compliance with SEC Rule 144. Each certificate or instrument evidencing the Registrable Securities transferred as above provided shall bear, except if such transfer is made pursuant to SEC Rule 144, the restrictive legend provided in Section 2.2, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for Kennedy and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act.

3.1 Demand Registration.

(a) If at any time after the expiration of the Restriction Period and the Company is eligible to use a Form S-3 registration statement, the Company receives a written request from Kennedy that the Company file a Form S-3 registration statement with respect to outstanding Registrable Securities having an anticipated aggregate offering price, net of Selling Expenses, of at least $2.0 million, then the Company shall as soon as practicable, and in any event within sixty (60) days after the date such request is given, file a Form S-3 registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration by Kennedy, and in each case, subject to the limitations of Section 3.1(b) and Section 3.3. Kennedy may request one such registration in any 12-month period. A registration shall not be counted against the one registration request to which Kennedy is entitled in any 12 month period (i) until the registration statement has become effective and the Company has complied in all material respects with its obligations under this Agreement with respect thereto, or (ii) if after the registration statement has become effective, either (1) the offering and/or sale

5

of Registrable Securities pursuant thereto becomes the subject of any stop order, injunction or other order or requirement of the SEC, any state securities administrator, securities exchange or self-regulatory body, or if any court or other governmental entity, securities exchange or self-regulatory body otherwise limits such offer and or sale, or (2) such registration statement does not remain effective for the time period set forth in Section 3.4(a). Kennedy may withdraw all or any part of his Registrable Securities from any demand registration hereunder at any time before the effectiveness of the applicable registration statement. In the event of such a withdrawal, such request shall be counted against the one registration request to which Kennedy is entitled in any 12 month period unless (x) the withdrawal is made as a result of the failure of the Company to comply with the provisions of this Agreement or any law, rule or regulation governing the offer or sale of securities or (y) Kennedy reimburses the Company for all Registration Expenses incurred by the Company in connection with such registration.

(b) Notwithstanding the foregoing obligations, if the Company furnishes to Kennedy a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board it would be materially detrimental to the Company and its stockholders for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (i) materially interfere with a significant acquisition, corporate reorganization or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than seventy-five (75) days after the request of Kennedy is given; provided, however, that the Company may not invoke this right more than two times in any twelve (12) month period; and provided, further, that the Company shall not register any securities for its own account or that of any other stockholder during such seventy-five (75) day period other than an Excluded Registration. If, following any such seventy-five (75) day period, Kennedy desires to exercise his registration right pursuant to Section 3.1(a), Kennedy shall resubmit a written request for registration to the Company pursuant to Section 3.1(a).

3.2 Company Registration. If at any time after the Restriction Period the Company proposes to register (including, for this purpose, a registration effected by the Company for stockholders other than Kennedy) any of its Common Stock under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give Kennedy notice of such registration. Upon the request of Kennedy given within five (5) days after such notice is given by the Company, the Company shall, subject to the provisions of Section 3.3, cause to be registered all of the Registrable Securities that Kennedy has requested to be included in such registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3.2 before the effective date of such registration, whether or not Kennedy has elected to include Registrable Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Section 3.6.

3.3 Underwriting Requirements.

(a) If, pursuant to Section 3.1, Kennedy intends to distribute the Registrable Securities covered by his request by means of an underwriting, he shall so advise the Company as a part of his request made pursuant to Section 3.1. The underwriter(s) will be selected by the Company, subject to the reasonable approval of Kennedy. Kennedy shall (together with the Company as provided in Section 3.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting.

(b) The Company, in its sole discretion, may require that a request made under Section 3.1 be made pursuant to an underwritten offering by an underwriter chosen by the Company and reasonably acceptable to Kennedy.

(c) In connection with any offering involving an underwriting of shares of the Company’s Common Stock pursuant to Section 3.2, the Company shall not be required to include any of Kennedy’s Registrable Securities in such underwriting unless Kennedy accepts the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by Kennedy to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of Registrable Securities which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering in the following priority:

7

3.4 Obligations of the Company. Whenever required under this Section 3 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 commercially reasonable efforts to cause such registration statement to become effective and keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that (i) such one hundred twenty (120) day period shall be extended for a period of time equal to the period Kennedy refrains, at the request of an underwriter of Common Stock (or other securities) of the Company, from selling any securities included in such registration, and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such one hundred twenty (120) day period shall be extended for up to sixty (60) days, if necessary, to keep the registration statement effective until all such Registrable Securities are sold;

(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 Securities Act in order to enable the disposition of all securities covered by such registration statement;

(c) furnish to Kennedy such numbers of copies of a prospectus, including a preliminary prospectus, as required by the Securities Act, and such other documents as Kennedy may reasonably request in order to facilitate his disposition of his Registrable Securities;

(d) use its commercially reasonable 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 Kennedy; provided, that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(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 underwriter(s) of such offering;

(f) use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(h) promptly make available for inspection by any managing underwriter(s) participating in any disposition pursuant to such registration statement,

8

and any attorney or accountant or other agent retained by any such underwriter, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any underwriter, attorney, accountant or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith;

(i) notify Kennedy promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and

(j) after such registration statement becomes effective, notify Kennedy of any request by the SEC that the Company amend or supplement such registration statement or prospectus.

3.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 3 with respect to the Registrable Securities of Kennedy that Kennedy shall furnish to the Company such information regarding Kennedy, the Registrable Securities held by him, and the intended method of disposition of such securities as is reasonably required to effect the registration of the Registrable Securities.

3.6 Expenses of Registration. All Registration Expenses shall be borne and paid by the Company. All Selling Expenses relating to Registrable Securities registered pursuant to Section 3 shall be borne and paid by Kennedy.

3.7 Indemnification. If any Registrable Securities are included in a registration statement under this Section 3:

(a) To the extent permitted by law, the Company will indemnify and hold harmless Kennedy and any underwriter (as defined in the Securities Act), against any Damages, and the Company will pay to Kennedy and any underwriter any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 3.7(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of Kennedy or any underwriter, expressly for use in connection with such registration.

(b) To the extent permitted by law, Kennedy will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if any), who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company and any

9

underwriter (as defined in the Securities Act), against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of Kennedy expressly for use in connection with such registration; and Kennedy will pay to the Company and any underwriter any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 3.7(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of Kennedy, which consent shall not be unreasonably withheld; and provided further, that in no event shall the aggregate amounts payable by Kennedy by way of indemnity or contribution under Sections 3.8(b) and 3.8(d) exceed the proceeds from the offering received by Kennedy (net of any Selling Expenses paid by Kennedy), except in the case of fraud or willful misconduct by Kennedy.

(c) Promptly after receipt by an indemnified party under this Section 3.7 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 3.7, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate 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 action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 3.7, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 3.7.

(d) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 3.7 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Section 3.7 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section 3.7, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is

10

appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect 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 allegedly untrue statement of a material fact, or the omission or alleged omission of 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; provided, however, that, in any such case, (x) Kennedy will not be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by Kennedy pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and, provided further, that in no event shall Kennedy’s liability pursuant to this Section 3.7(d), when combined with the amounts paid or payable by Kennedy pursuant to Section 3.7(b), exceed the proceeds from the offering received by Kennedy (net of any Selling Expenses paid by Kennedy), except in the case of willful misconduct or fraud by Kennedy.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company and Kennedy under this Section 3.7 shall survive the completion of any offering of Registrable Securities in a registration under this Section 3, and otherwise shall survive the termination of this Agreement.

3.8 Reports Under Exchange Act. With a view to making available to Kennedy the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit Kennedy to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall:

(a) use commercially reasonable efforts to make and keep available adequate current public information, as those terms are understood and defined in SEC Rule 144, at all times;

(b) use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(c) furnish to Kennedy, so long as Kennedy owns any Registrable Securities, forthwith upon request (i) to the extent accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144, the

11

Securities Act, and the Exchange Act, or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3; (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company; and (iii) such other information as may be reasonably requested in availing Kennedy of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to Form S-3.

5.1 Immediately following the Effective Time (as defined in the Merger Agreement), the Company’s board of directors shall be increased to eight (8) members and the Company’s board of directors shall fill the newly created vacancy by immediately appointing Kennedy to the Company’s board of directors as a Class I director, to serve until the 2017 annual meeting of the Company’s stockholders (and until their successors have been duly elected and qualified), in all cases subject to the satisfaction and compliance of Kennedy with Company’s then-current corporate governance guidelines, code of business conduct and ethics and other board of director policies relating to nomination and qualification of directors.

5.2 In the event that either (a) Kennedy is not elected to the Company’s Board of Directors immediately following the Effective Time, or (b) if at any time after the Effective Time that Kennedy is living and is not serving on the Board of Directors of the Company, this Agreement shall be automatically amended (without the need for any consent, approval or signatures of any party hereto) to delete Sections 2.1 and 2.5 from this Agreement and such sections shall be thereafter null and void and of no further force nor effect.

This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

6.6 Jurisdiction and Venue. Each of the Parties irrevocably agrees that any legal action or proceeding arising out of or related to this Agreement or for recognition and enforcement of any judgment in respect hereof brought by any other Party hereto or its successors or assigns may be brought and determined in the state or federal courts located in New Castle County, Delaware, and each of the Parties hereby irrevocably submits to the exclusive jurisdiction of the aforesaid courts for itself and with respect to its property, unconditionally, with regard to any such action or proceeding arising out of or relating to this Agreement and the transactions contemplated hereby (and agrees not to commence any action, suit or proceeding relating thereto except in such courts). Each of the Parties agrees further to accept service of process in any manner permitted by such court. Each of the Parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or related to this Agreement or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the above-referenced courts for any reason other than the failure lawfully to serve process, (b) that it or its property is exempt or immune from jurisdiction of such courts or from any legal process commenced therein, and (c) to the fullest extent permitted by law, that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such court. The exclusive choice of forum set forth herein shall not be deemed to preclude the enforcement of any judgment obtained in such forum or the taking of any action under this Agreement to enforce such judgment in any appropriate jurisdiction.

6.7 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.
