(i) prepare and file with the Commission a Registration Statement on an appropriate form under the Securities Act available for the sale of the Shares by the Selling Holders in accordance with the intended method or methods of distribution thereof; provided, however, that the Company shall (a) before filing, furnish to one firm of counsel for the Selling Holders (selected by a majority of the Selling Holders) within a reasonable period of time (but in any event at least two business days) prior to the filing hereof with the Commission to afford to such counsel, the Selling Holders and its counsel a reasonable opportunity for review, copies of the Registration Statement or Prospectus proposed to be filed, and (b) reflect in each such document, when so filed with the Commission, such written comments as such counsel to the Selling Holders may reasonably propose;

(ii) furnish, at its expense, to the Selling Holders such number of conformed copies of the Registration Statement and each amendment thereto, of the Prospectus and each supplement thereto, and of such other documents as the Selling Holders reasonably may request in writing from time to time;

3

(iii) prepare and file with the Commission any amendments and post-effective amendments to the Registration Statement as may be necessary and any supplements to the Prospectus as may be required or appropriate, in the view of the Company and its counsel, by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act to keep the Registration Statement effective during the Required Period;

(iv) promptly following its actual knowledge thereof (but in any event within two business days), notify the Selling Holders in writing:

(a) when a Registration Statement, Prospectus, Issuer Free Writing Prospectus (as defined in Rule 433 under the Securities Act) or any supplement or amendment has been filed and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective;

(b) of any comments or inquiries by the Commission or any request by the Commission or any other governmental authority for amendments or supplements to a Registration Statement, Prospectus or Issuer Free Writing Prospectus or for additional information (and to furnish the Selling Holders with copies of any correspondence related thereto);

(c) of the issuance by the Commission or any other governmental authority of any stop order or order preventing or suspending the effectiveness of a Registration Statement or the use of any Prospectus or the initiation or threatening of any proceedings for that purpose;

(d) of the receipt by the Company of any written notification with respect to the suspension of the qualification or exemption from qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

(e) of the occurrence of any event during the period a Registration Statement is effective which makes any statement made in the Registration Statement or the Prospectus or any Issuer Free Writing Prospectus untrue in any material respect or which requires the making of any changes in such Registration Statement, Prospectus or Issuer Free Writing Prospectus so that such Registration Statement, Prospectus or Issuer Free Writing Prospectus shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (provided, however, that no notice by the Company shall be required pursuant to this Section 5(a)(iv)(e) in the event that the Company either promptly files a Prospectus supplement to update the Prospectus or an appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which, in either case, contains the requisite information that results in such Registration Statement no longer containing any untrue statement of a material fact or omitting to state a material fact necessary to make the statements therein or in light of the circumstances under which they were made, not misleading); and

4

(f) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be required by applicable law (in which case the Company shall file the same as soon as practicable after such determination and use its commercially reasonable efforts to cause the same to become effective as soon as practicable following filing);

(v) use its commercially reasonable efforts to prevent the issuance of or obtain the withdrawal of any order suspending the effectiveness of a Registration Statement, or the lifting of any suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction, at the earliest practicable date;

(vi) as promptly as reasonably practicable after the occurrence of any event contemplated by Section 5(a)(iv)(e) or 5(a)(iv)(f) hereof, use its commercially reasonable efforts to prepare (and furnish at its expense, subject to any notice by the Company in accordance with Section 5(a)(iv), to the Selling Holders a reasonable number of copies of) a supplement or post-effective amendment to the applicable Registration Statement or a supplement to the related Prospectus (including by means of an Issuer Free Writing Prospectus), or file any other required document so that, as thereafter delivered to the purchasers of the Shares being sold thereunder, such Prospectus or Issuer Free Writing Prospectus shall not contain an untrue statement of a material fact or omit to state any 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;

(vii) use its commercially reasonable efforts to (a) obtain all other approvals, consents, exemptions or authorizations from such governmental authorities as may be necessary to enable the selling Holders to consummate the disposition of such Shares and (b) comply with all applicable rules and regulations of the Commission relating to such registration and make generally available to its securityholders earning statements satisfying the provisions of Section 11(a) of the Securities Act, provided that the Company shall be deemed to have complied with this Section if it has satisfied the provisions of Rule 158 under the Securities Act (or any similar rule promulgated under the Securities Act);

(viii) use its commercially reasonable efforts to (a) ensure a CUSIP number has been assigned to all Shares and provide or cause to be maintained a transfer agent and registrar for all such Shares not later than the effectiveness of such Registration Statement , and (b) cause all Shares covered by the applicable Registration Statement quoted on the NASDAQ Global Market or such other principal national securities exchange on which the EXAC Stock is then listed, to continue to be so listed or quoted for a reasonable period of time after the offering;

5

(ix) use its commercially reasonable efforts to (a) procure the cooperation of the Company’s transfer agent in settling any offering or sale of Shares and (b) cooperate with the selling Holders of Shares to facilitate the timely preparation and delivery of certificates not bearing any restrictive legends representing the Shares to be sold, and cause such Shares to be issued in such denominations and registered in such names, in accordance with the instructions of the selling Holders of Shares at least three business days prior to any sale of Shares;

(x) use its commercially reasonable efforts to provide such information as may be reasonably required for any filings required to be made by the Selling Holders with the National Association of Securities Dealers, Inc. (the “NASD”) in connection with the offering under any Registration Statement of the Shares (including, without limitation, such as may be required by NASD Rule 2710 or 2720), and, upon the written request of the Selling Holders, shall use its commercially reasonable efforts to cooperate in connection with any filings required to be made with the NASD in that regard on or prior to the filing of any Registration Statement; and

(xi) hold in confidence and not make any disclosure of information concerning a Holder provided to the Company unless (a) disclosure of such information is necessary to comply with federal or state securities laws, (b) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (c) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction, or (d) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement; and, upon learning that disclosure of such information concerning a Holder is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Holder and allow such Holder, at the Holder’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

(b) The Company may require each Holder of Shares as to which any registration is being effected to (i) furnish the Company such information regarding such Holder and the distribution of such securities as the Company may from time to time reasonably request in writing and (ii) otherwise agree to comply with the Securities Act and the Exchange Act in connection with the registration and distribution of the Shares.

(c) Upon receipt of any notice from the Company of the happening of any event of the kind described in clause (iv)(e) of Section 5(a) hereof or to the extent the Board of Directors of the Company otherwise reasonably determines in good faith that the continued effectiveness of the filing of such Registration Statement at such time would be materially detrimental to the Company and it is therefore necessary to suspend the filing of such Registration Statement, the Company may suspend the effectiveness of such Registration Statement for a period of time not to exceed 90 days in any 12 month period (the “Noneffective Period”), and such Holder will forthwith discontinue such Holder’s disposition of Shares pursuant to the registration statement relating to such Shares until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by clause (iv)(e) of Section 5(a) hereof, or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and, if so directed by the Company, such Holder will promptly deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the prospectus relating to such Shares current at the time of receipt of such notice.

6

(d) If the Company suspends a registration statement or requires Holders to cease sales of Shares pursuant to this Section 5, the Company shall, as promptly as practicable following the termination of the circumstances that entitled the Company to do so, take such actions as may be necessary to reinstate the effectiveness of such registration statement and/or give written notice to all Holders of Shares authorizing them to resume sales pursuant to such registration statement.

6. Registration Expenses. The costs and expenses (other than underwriting discount or commission, and other fees, expenses or costs payable to any underwriter, broker or dealer and such fees and expenses as state securities officials may require that the Holders pay) of all registrations and qualifications under the Securities Act, and all other actions that the Company is required to take or effect pursuant to this Agreement, shall be paid by the Company, including, without limitation, all registration and filing fees, printing, duplication, mailing and delivery expenses, costs of special audits incident to or required by any such registration, expenses relating to blue-sky compliance and listing of the Shares on any applicable exchange pursuant to the terms of this agreement and fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel chosen by the Holders to represent all of the Holders.

7. Indemnification.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Holder owning Shares registered pursuant to this Agreement, such Holder’s Affiliates, and their respective officers, directors, employees and agents, and each Person, if any, who controls any such Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively referred to for purposes of Sections 7 through 9 of this Agreement as a “Holder”), from and against any and all losses, claims, damages and liabilities (including without limitation, subject to Section 8, the reasonable legal fees and other reasonable out-of-pocket expenses incurred in investigating, responding to or defending against any claim, challenge, litigation, investigation or proceeding, including without limitation, all costs of appearing as a witness in any claim, challenge, litigation, investigation or proceeding) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement pursuant to which any Shares were registered under the Securities Act, Prospectus or preliminary prospectus or Issuer Free Writing Prospectus, or any amendment thereof or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary, in the case of any Prospectus or Issuer Free Writing Prospectus, in light of the circumstances under which they were made, to make the statements therein not misleading; provided, however, that the Company shall not be liable 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 an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, Prospectus, amendment, supplement or Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by such participating Holder or any other Person who participates as an underwriter in the offering or sale of such securities, in either case specifically stating that it is for use in the preparation thereof

7

or that is corrected in any subsequent prospectus that was delivered to Holders at least two business days prior to the relevant sale date. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any participating Holder or any such underwriter or controlling Person and shall survive the transfer of such securities by the Holder.

(b) Indemnification by Holders. Each Holder agrees, severally and not jointly, to indemnify and hold harmless, the Company, the directors, and officers of the Company and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity contained in Section 7(a) from the Company to the Holders, as incurred, but only with respect to information relating to such Holder in conformity with such written information as furnished to the Company in writing by such Holder expressly for use in any Registration Statement, Prospectus or preliminary prospectus or Issuer Free Writing Prospectus, or any amendment or supplement thereto.

8. Conduct of Indemnification Proceedings. If any claim, challenge, litigation, investigation or proceeding (including any governmental or regulatory investigation) shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to either of Section 7(a) or Section 7(b), such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Person”) in writing; provided that (i) the omission to so notify the Indemnifying Party shall not relieve it from any liability that it may have hereunder except to the extent it has been materially prejudiced by such failure and (ii) the omission to so notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than on account of Sections 7 through 9 of this Agreement. In case any such claim, challenge, litigation, investigation or proceeding is brought against any Indemnified Person and it notifies the Indemnifying Person of the commencement thereof, the Indemnifying Person shall be entitled to participate therein and, to the extent that it may elect by written notice delivered to such Indemnified Person, to assume the defense thereof and retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed in writing to the contrary, (ii) the Indemnifying Person shall have failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person as contemplated by the preceding sentence or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Holders and such control Persons of the Holders shall be designated in writing by such Holders and any such separate firm for the Company, the directors and officers of the Company and such control Persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for

8

any settlement of any pending or threatened proceeding effected without its prior written consent (which consent shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify in accordance with, and subject to the limitations of, Section 7(a) and Section 7(b) above, as the case may be, any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding anything in this Section 8 to the contrary, if at any time an Indemnified Person shall have requested the Indemnifying Party to reimburse such Indemnified Person for legal or other expenses in connection with investigating, responding to or defending any Proceedings as contemplated by Sections 7 through 9 of this Agreement, the Indemnifying Party shall be liable for any settlement of any Proceedings effected without its written consent if (i) such settlement is entered into more than (x) 60 days after receipt by the Indemnifying Party of such request for reimbursement and (y) 30 days after receipt by the Indemnified Party of the material terms of such settlement and (ii) the Indemnifying Party shall not have reimbursed such Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Persons (which consent shall not be unreasonably withheld), effect any settlement of any pending proceeding in respect of which any Indemnified Person is a party or of any threatened proceeding in respect of which any Indemnified Person could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (i) includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

9. Contribution, etc.

(a) If the indemnification provided for in Sections 6 through 8 of this Agreement is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Holder on the other hand with respect to the sale by such Holder of Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of such Holder on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and such Holder on the other shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by such Holder and the parties’ relevant intent, knowledge, information and opportunity to correct or prevent such statement or omission.

9

(b) The Company and the Holders agree that it would not be just and equitable if contribution pursuant to Sections 7 through 9 of this Agreement were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation that does not take account of the equitable considerations referred to in this Section 9. The amount paid or payable by an Indemnified Person as a result of losses, claims, damages and liabilities referred to in this Section 9 shall be deemed to include, subject to the limitations set forth in Sections 7 and 8 above, any reasonable legal or other reasonable out-of-pocket expenses incurred by such Indemnified Person not otherwise reimbursed in connection with investigating or defending any such action or claim. Notwithstanding the provisions of Sections 7 through 9 of this Agreement, in no event shall any Holder be required to contribute any amount in excess of the amount by which the total amount received by such Holder with respect to its sale of Shares pursuant to any Registration Statement exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(c) The remedies provided for in Sections 7 through 9 of this Agreement are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity.

(d) The indemnity and contribution agreements contained in Sections 7 through 9 of this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder or any Person controlling any Holder or by or on behalf of the Company, the officers or directors of each of the Company or any other Person controlling the Company and (iii) the sale by a Holder of Shares covered by any Registration Statement.

10. Priority. The indemnification provisions contained in this Agreement shall supersede the general indemnification provisions in the Merger Agreement.

11. Rule 144. With a view to making available the benefits of certain rules and regulations of the Commission which may permit the sale of Shares to the public without registration, the Company agrees to (a) use its commercially reasonable 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; (b) upon written request of any Holder of Shares, furnish to such Holder promptly 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, and such other reports and documents as any Holder reasonably may request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any Shares without registration; and (c) take such other actions as may be reasonably required to consummate any distribution of Shares that may be permitted in accordance with the terms and conditions of Rule 144.

12. Private Placement. The Company agrees that nothing in this Agreement shall prohibit the Holders, at any time and from time to time, from selling or otherwise transferring Shares pursuant to a private placement or other transaction which is not registered pursuant to the Securities Act. To the extent requested by a Holder, the Company shall take all reasonable steps necessary to assist and cooperate with such Holder to facilitate such sale or transfer.
