The Company shall, within five (5) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each such Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Demand Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company.

Under no circumstances shall the Company be obligated to effect more than two Registrations for the enGene Holders and two Registrations for the Sponsor Holders pursuant to a Demand Registration under this Section 2.1.1.]

2.1.3 Effective Registration. Notwithstanding the provisions of Section 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (a) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and remains effective for not less than 180 days (or such shorter period as shall terminate when all Registrable Securities covered by such Registration Statement have been sold or withdrawn), or if such Registration Statement relates to an Underwritten Offering, such longer period as, in the opinion of counsel for the Underwriter or Underwriters, a Prospectus is required by law to be delivered in connection with sales of Registrable Securities by an Underwriter or dealer and (b) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, however, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared effective for purposes of counting Registrations under Section 2.1.1 above unless and until (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, however, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or has been terminated.

Subject to the provisions of Section 2.1.5 and Section 2.4 hereof, if a Demanding Holder advises the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Demand Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this Section 2.1.4 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Demanding Holder initiating the Demand Registration, which Underwriter(s) shall be reasonably acceptable to the Company.

best efforts to file a shelf registration on an appropriate form as promptly as practicable to replace the shelf registration statement on Form S-3 and have such replacement Resale Shelf Registration Statement declared effective as promptly as practicable and to cause such replacement Resale Shelf Registration Statement to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Resale Shelf Registration Statement is available or, if not available, that another Resale Shelf Registration Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities; provided, however, that at any time the Company once again becomes eligible to use Form S-3, the Company shall cause such replacement Resale Shelf Registration Statement to be amended, or shall file a new replacement Resale Shelf Registration Statement, such that the Resale Shelf Registration Statement is once again on Form S-3. Once effective, the Company shall use commercially reasonable efforts to keep the Resale Shelf Registration Statement that is required to be filed pursuant to this Section 2.3.1 and Prospectus included therein continuously effective and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available at all times until the earlier of (i) the third anniversary of the Closing, and (ii) as to any particular Holder, the date on which the Holder ceases to hold any Registrable Securities. The Registration Statement filed with the Commission pursuant to this Section 2.3.1 shall contain a Prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such Registration Statement (subject to the Lock-Up Period applicable to such Holder, which shall control), and shall provide that such Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by, Holders. The Resale Shelf Registration Statement filed hereunder may also register Common Shares other than Registrable Securities, including shares sold by the Company in one or more PIPE transactions and shares issuable upon the exercise of warrants.

2.3.2 Notification and Distribution of Materials. The Company shall notify the Holders in writing of the effectiveness of the Resale Shelf Registration Statement as soon as practicable, and in any event within three (3) Business Days after the Resale Shelf Registration Statement becomes effective (which may be accomplished by the issuance of a press release with such information), and shall furnish to any Holder, without charge, at its request, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the Prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Holders may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement (to the extent any of such documents are not available on EDGAR).

2.3.3 SEC Cutback. Notwithstanding the registration obligations set forth in this Section 2.3, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof and use its reasonable best efforts to file amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”) on Form S-3, or if Form S-3 is not then available to the Company for such registration statement,

on such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall use its reasonable best efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly-available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”). Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a Holder as to further limit its Registrable Securities to be included on the Registration Statement, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a pro rata basis based on the total number of Registrable Securities held by the Holders, subject to a determination by the Commission that certain Holders must be reduced first based on the number of Registrable Securities held by such Holders. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its reasonable best efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf Registration Statement, as amended, or the New Registration Statement.

2.3.4 Underwritten Shelf Takedown. At any time and from time to time after a Resale Shelf Registration Statement has been declared effective by the Commission, to the extent such Resale Shelf Registration may be used for an underwritten offering, any of the Demanding Holders may request to sell all or any portion of the Registrable Securities in an underwritten offering that is registered pursuant to the Resale Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided, however, that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include securities with a total offering price (including piggyback securities and before deduction of underwriting discounts) reasonably expected to exceed, in the aggregate, $10,000,000. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Within five (5) days of receipt of this notice, the Company must notify all of the Holders of Registrable Securities of the Underwritten Shelf Takedown. Within five (5) days of delivery of this notice, Holders of Registrable Securities must notify the Company if they wish to participate in the Underwritten Shelf Takedown. The Company shall include in any Underwritten Shelf Takedown the securities requested to be included by any Holder within such specified timeframe (each a “Takedown Requesting Holder”). All such Holders proposing to distribute their Registrable Securities through an Underwritten Shelf Takedown under this Section 2.3.4 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Takedown Requesting Holder (who must be reasonably acceptable to the Company).

2.3.5 Reduction of Underwritten Shelf Takedown. If the managing Underwriter(s) in an Underwritten Shelf Takedown, in good faith, advise the Company and the Takedown Requesting Holders in writing that the dollar amount or number of Registrable Securities that the Takedown Requesting Holders desire to sell, taken together with all other Common Shares or other equity securities that the Company desires to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Underwritten Shelf Takedown, as follows: (i) first, the Registrable Securities of the Demanding Holders, on a Pro Rata basis, (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing section (i), the Registrable Securities of the Takedown Requesting Holders, on a Pro Rata basis, that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), Common Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities.

2.3.6 Registrations effected by the Company pursuant to Section 2.3.1 shall not be counted as Demand Registrations effected pursuant to Section 2.1.

2.3.7 Under no circumstances shall the Company be obligated to effect more than three Underwritten Shelf Takedowns for the enGene Holders and three Underwritten Shelf Takedowns for the Sponsor Holders pursuant to Section 2.3.4].

Section 2.4 Restrictions on Registration Rights. Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to (but may, at its sole option) file a Registration Statement pursuant to a Demand Registration request made under Section 2.1 during the period starting with the date thirty (30) days prior to Company’s good faith estimate of the date of the filing of, and ending on a date ninety (90) days after the effective date of, a Company initiated Registration and provided that Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to Section 2.1.1 and that New Holdco continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective.

Section 2.5 Other Registration Rights. The Company represents that, as of the date hereof and other than as set forth herein, no Person has the right to request or require it to register any equity securities issued by it, other than (i) such registration rights granted pursuant to the PIPE Financing, the Convertible Bridge Financing and the Non-Redemption Agreement, each as defined in the Business Combination Agreement, and (ii) such registration rights as applicable under the terms of the Warrants. The Company will not grant any Person any registration rights with respect to the equity of the Company that are prior in right or in conflict or inconsistent with the rights of the Holders as set forth in this Article II in any material respect (it being understood that this shall not preclude the grant of additional demand and piggyback registration rights in and of themselves so long as such rights are not prior in right to the rights under this Agreement).

ARTICLE III

COMPANY PROCEDURES

Section 3.1 General Procedures. If at any time on or after the Effective Time the Company is required to effect the Registration of Registrable Securities, the Company shall use its reasonable best efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible:

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by the Holders or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus or are no longer outstanding;

3.1.3 prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriter(s), if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration or the legal counsel for any such Holders may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holders; provided, that the Company will not have any obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system;

3.1.4 prior to any public offering of Registrable Securities, use its reasonable best efforts to: (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.5 cause all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed;

3.1.6 provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of such Registration Statement;

3.1.7 advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

3.1.8 advise each Holder of Registrable Securities covered by such Registration Statement, 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 (provided that any such notice may be made by the issuance of a press release including such information);

3.1.9 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or its counsel; provided, that the Company will not have any obligation to provide any document pursuant to this clause that is or will become available on the Commission’s EDGAR system;

3.1.10 notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

3.1.11 permit a representative of the Holders, the Underwriter(s), if any, and any attorney or accountant retained by such Holders or Underwriter(s) to participate in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter(s), attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriter(s) enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.12 in the event of an Underwritten Offering, request a customary “comfort” letter from the Company’s independent registered public accounting firm, addressed to the Underwriter(s) and in customary form and covering such matters of the type customarily covered by “comfort” letters as the managing Underwriter(s) may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders and such managing Underwriter;

3.1.13 in the event of an Underwritten Offering, request one or more customary legal opinions of counsel representing the Company for the purposes of such Registration, addressed to the Underwriter(s) and “negative assurance letters” covering such matters with respect to the Registration in respect of which such opinions and letters are being given as the Underwriter(s) may reasonably request and as are customarily included in such opinions and negative assurance letters;

3.1.14 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter(s) of such offering;

3.1.15 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission);

3.1.16 if a Registration, including an Underwritten Offering, use its commercially reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter(s) in any Underwritten Offering; and

3.1.17 otherwise, in good faith, use commercially reasonable efforts to cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with such Registration.

Section 3.2 Registration Expenses. All Registration Expenses shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

Section 3.3 Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements.

Section 3.4 Suspension of Sales; Adverse Disclosure. The Company shall promptly notify each of the Holders in writing if a Registration Statement or Prospectus contains a Misstatement and, upon receipt of such written notice from the Company, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement, provided that the Company hereby covenants promptly to prepare and file any required supplement or amendment correcting any Misstatement promptly after the time of such notice and, if necessary, to request the immediate effectiveness thereof. If the filing, initial effectiveness or continued use of a Registration Statement or Prospectus included in any Registration Statement at any time (a) would require the Company to make an Adverse Disclosure, (b) would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, (c) requires the Company to update the financial statements contained in such Registration Statement pursuant to the rules and regulations of the Commission through the filing

of a post-effective amendment which is subject to potential Commission review, or (d) in the good faith judgment of the Chief Executive Officer or Chief Financial Officer of the Company, which judgment shall be documented in writing and provided to the Holders in the form of a written certificate signed by such officer, such filing, initial effectiveness or continued use of a Registration Statement would be materially detrimental to the Company. the Company shall have the right to defer the filing, initial effectiveness or continued use of any Registration Statement pursuant to (a), (b) or (c) for a period of not more than ninety (90) days in any three hundred and sixty (360)-day period. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

Section 3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, shall expend commercially reasonable efforts to (i) file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act (and upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements), and (ii) take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Common Shares held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including using commercially reasonable efforts to cause any legal opinions to be delivered.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

Section 4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriter(s), their officers and directors and each person who controls (within the meaning of the Securities Act) such Underwriter(s) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall, severally and not jointly, indemnify the Company, its directors and officers and agents and each person who controls (within the meaning of the Securities Act) the Company against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriter(s), their officers, directors and each person who controls (within the meaning of the Securities Act) such Underwriter(s) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, however, that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or Affiliate of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution (pursuant to Section 4.1.5) to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall to the extent permitted by law contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by a court of law by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.2, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

ARTICLE V

LOCK-UP

Section 5.1 Lock-Up.

5.1.1 Each Holder agrees, and the Company agrees and shall cause each director and officer of the Company to agree, that, in connection with each Registration or sale of Registrable Securities pursuant to Section 2.1, Section 2.2 or Section 2.3 conducted as an Underwritten Offering, if requested, to become bound by and to execute and deliver a customary lock-up agreement with the underwriter(s) of such Underwritten Offering restricting such applicable person or entity’s right to (a) Transfer, directly or indirectly, any equity securities of the Company held by such person or entity or (b) enter into any swap or other arrangement that Transfers to another any of the economic consequences of ownership of such securities during the period commencing on the date of the final Prospectus relating to the Underwritten Offering and ending on the date specified by the underwriters (such period not to exceed ninety (90) days). The terms of such lock-up agreements shall be negotiated among the applicable Holders requested to enter into lock-up agreements in accordance with the immediately preceding sentence, the Company and the underwriters and shall include customary exclusions from the restrictions on Transfer set forth therein, including that such restrictions on the applicable Holders shall be conditioned upon all officers and directors of the Company, as well as all such applicable Holders, being subject to the same restrictions; provided, however, to the extent any Holder is granted a release or waiver from the restrictions contained in this Section 5.1. and in such Holder’s lock-up

agreement prior to the expiration of the period set forth in such Holder’s lock-up agreement, then all applicable Holders shall be automatically granted a release or waiver from the restrictions contained in this Section 5.1 and the applicable lock-up agreements to which they are party to the same extent, on substantially the same terms as and on a pro rata basis with, the Holder to which such release or waiver is granted. The provisions of this Section 5.1 shall not apply to any Holder that then holds less than one percent (1%) of then total issued and outstanding Common Shares.

ARTICLE VI

TERMINATION

Section 6.1 Prior Agreement Termination. By execution and delivery of this Agreement and contingent upon the occurrence of, and effective as of, Closing, FEAC and Sponsor (who represents and warrants that it holds at least a majority-in-interest of the “Registrable Securities” under the Prior Agreement), hereby terminate in its entirety the Prior Agreement pursuant to the power and authority granted to FEAC and the holders of at least a majority-in-interest of such “Registrable Securities” in Section 6.5 of the Prior Agreement.

Section 6.2 Termination. This Agreement shall terminate in the case of any Holder, the date on which neither the Holder nor any of its permitted assignees holds any Registrable Securities.

Section 7.2 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 7.3 Entire Agreement; Assignment. This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), by any party without the prior express written consent of the other parties hereto.

Section 7.4 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto (and its respective permitted assigns), and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

To the fullest extent permitted by law, the Company hereby renounces (for itself and on behalf of its subsidiaries) any interest or expectancy in, or in being notified of or offered an opportunity to participate in, any Specified Activity that may be presented to or become known to Sponsor, its Affiliates or Portfolio Companies or any Sponsor Director, other than any such Specified Activity that was learned, discovered or sourced solely in the course of a Sponsor Director acting in such Sponsor Director’s capacity as a director of the Company or any of its Affiliates.
