If a Registration is for a Registered public offering involving an underwriting in which any other holders of Parent Common Stock will sell shares to the underwriter, the Parent shall so advise the Stockholders’ Agent by written notice (which shall include a list of the jurisdictions in which the Parent intends to attempt to qualify such securities under the applicable Blue Sky or other state securities laws). In such event the holder of the Parent Common Stock may participate in the underwritten offering subject to Registration to the extent provided in this Section 1.13 solely to the extent any such holders distributing their securities through such underwriting enter into an underwriting agreement with the underwriter selected by the Parent (the “ Underwriter’s Representative ”) for such offering. The holders of Parent Common Stock received as Merger Consideration shall have no right to participate in the selection of the underwriters for an offering pursuant to this Section 1.13.

(c) Marketing Limitation in Piggyback Registration . In the event the Underwriter’s Representative advises the recipients of Merger Consideration seeking Registration of Registrable Securities pursuant to Section 1.13(b) in writing that market factors (including, without limitation, the aggregate number of shares of Parent Common Stock requested to be Registered, the general condition of the market, and the status of the persons proposing to sell securities pursuant to the Registration) require a limitation of the number of shares to be underwritten, the Underwriter’s Representative (subject to the allocation priority set forth in Section 1.13(d)) may exclude some or all Registrable Securities from such Registration and underwriting.

(d) Allocation of Shares in Piggyback Registration . In the event that the Underwriter’s Representative limits the number of shares to be included in a Registration

6

pursuant to Section 1.13(c), the number of shares to be included in such Registration shall be allocated (subject to Section 1.13(c)) in the following manner: The number of shares, if any, that may be included in the Registration and underwriting by selling stockholders shall be allocated among all the Persons holding Parent Common Stock participating in such underwritten offering, in proportion, as nearly as practicable, to the respective amounts of securities (including Registrable Securities) which such Persons request inclusion in such Registration. No Registrable Securities or other securities excluded from the underwriting by reason of this Section 1.13(d) shall be included in the Registration Statement. To facilitate the allocation of shares in accordance with the above provisions, the Parent or the Underwriter’s Representative may round the number of shares allocated to any Person to the nearest one hundred (100) shares.

Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such Registration.

(f) Blue Sky in Piggyback Registration . In the event of any Registration of Registrable Securities pursuant to this Section 1.13, the Parent will use commercially reasonable efforts to Register and qualify the securities covered by the Registration Statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably appropriate for the distribution of such securities; provided, however, that (i) the Parent 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, and (ii) notwithstanding anything in this Agreement to the contrary, in the event any jurisdiction in which the securities shall be qualified imposes a non-waivable requirement that expenses incurred in connection with the qualification of the securities be borne by selling stockholders, such expenses shall be payable pro rata by selling stockholders.

1.14 Registration Procedures . In the case of each registration, qualification or compliance effected by the Parent pursuant to Section 1.13, the following will apply:

(b) Parent shall keep each recipient of Merger Consideration whose Registrable Securities are included in any Registration pursuant to Section 1.13 advised as to the initiation and completion of such Registration. At its expense, the Parent will: (i) use its commercially reasonable efforts to keep any Section 1.13(a) Registration effective for a period of one hundred twenty (120) days or until the Person or Persons have completed the distribution described in the Registration Statement relating thereto, whichever first occurs; and (ii) furnish such number of prospectuses (including preliminary prospectuses) in conformity with the Securities Act and such other documents as such Person or Persons from time to time may reasonably request. With respect to clause (i) of the preceding sentence, the Parent may at any time upon written notice to the participating Persons delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and such

7

Persons hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during such time) if the Parent reasonably believes that the Parent may, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose its earnings report or any other corporate development, the disclosure of which could reasonably be expected to have an adverse effect upon the Parent, its stockholders, a potentially significant transaction or event involving the Parent, or any negotiations, discussions, or proposals directly relating thereto.

(c) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statements as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the periods specified in Section 1.13(b).

(d) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each recipient of Merger Consideration participating in such underwriting shall also enter into and perform its obligations under such an agreement.

(e) It shall be a condition precedent of the Parent’s obligations under Sections 1.13 and 1.14 of this Agreement that each recipient of Merger Consideration holding Registrable Securities to be included in any Registration furnish to the Parent such information regarding such Person and the distribution proposed by such Person as the Parent may reasonably request.

1.15 Termination of Registration Rights . The Registration rights set forth in Sections 1.13 and 1.14 shall terminate upon the earlier of (a) five (5) years after the date hereof or (b) when such recipient of Parent Common Stock is entitled to sell all of such Person’s Registrable Securities without volume restriction pursuant to Rule 144.

1.16 Appraisal Rights.

Notwithstanding the provisions of Section 1.10, if any holder of shares of Company Capital Stock who demands appraisal of such holder’s shares under the DGCL or the CGCL, as applicable, shall effectively withdraw or lose (through the failure to perfect or otherwise) such holder’s right to appraisal, then as of the

8

Closing or the occurrence of such event, whichever later occurs, such holder’s shares of Company Capital Stock shall automatically be converted into the right to receive the applicable Merger Consideration, if any, without interest thereon, promptly following the surrender of the certificate or certificates representing such shares of Company Capital Stock.

(c) Notice of Dissenting Shares .

1.17 Further Action.
