2.3 Piggyback Registration.

(a) If the Company at any time proposes to file a registration statement under the Securities Act with respect to any offering of its securities for its own account or for the account of any other Persons (other than (i) a registration on Form F-4 or S-8 or any successor form to such referenced forms or (ii) a registration of securities solely relating to an offering and sale to employees or directors of the Company pursuant to any employee stock plan or other employee benefit plan arrangement), then, as soon as practicable (but in no event less than 30 days prior to the proposed date of filing of such registration statement), the Company shall give written notice of such proposed filing to all Holders of Registrable Securities, and such notice shall offer each Holder the opportunity to Register under such registration statement such number of Registrable Securities as each such Holder may request in writing, except that such number shall not exceed the number of Registrable Securities which the Company was required but unable to register pursuant to Section 2.1 or 2.2, as applicable (a “Piggyback Registration”). Subject to the foregoing limitation and Section 2.3(b), the Company shall include in such registration statement all such Registrable Securities that are requested to be included therein within 15 days after such notice is delivered; provided that if at any time after giving written notice of its intention to Register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to Register or to delay registration of such securities, the Company shall give written notice of such determination to each Holder and, thereupon:

(i) in the case of a determination not to Register, shall be relieved of its obligation to Register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any Holders of Registrable Securities entitled to such registration under Section 2.1 or 2.2; and (ii) in the case of a determination to delay Registering, shall be permitted to delay Registering any Registrable Securities, for the same period as the delay in Registering such other securities. If the offering pursuant to such registration statement is to be underwritten, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.3(a) must, and the Company shall make such arrangements with the managing underwriter or underwriters so that each such Holder may, participate in such underwritten offering. If the offering pursuant to such registration statement is to be on any other basis, then each Holder making a request for a Piggyback Registration pursuant to this Section 2.3(a) must, and the Company shall make such arrangements so that each such Holder may, participate in such offering on such basis.

Each Holder of Registrable Securities shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration at any time prior to the effectiveness of such registration statement.

(b) If the managing underwriter or underwriters of any proposed underwritten offering of Registrable Securities included in a Piggyback Registration informs the Company and the Holders in writing that, in its or their opinion, the number of securities which such Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such registration shall be:

(i) first, up to 100% of the securities that the Company proposes to include in the offering;

Page 5

(ii) second, and only if all of the securities referred to in clause (i) have been included, up to 100% of the securities proposed to be offered by security holders having registration rights existing as of the date of this Agreement; and

(iii) third, and only if all of the securities referred to in clause (ii) have been included, pro rata among the Holders who have requested participation in such offering and any other holder of securities of the Company having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”). The pro rata allocations pursuant to clause (iii) for each selling Holder who has requested participation in such offering shall be the product of (a) the aggregate number of Registrable Securities proposed to be sold in such offering multiplied by (b) the fraction derived by dividing (x) the number of Registrable Securities owned on the Closing Date by such selling Holder by (y) the aggregate number of Registrable Securities owned on the Closing Date by all selling Holders who have requested participation in such offering plus the aggregate number of Parity Securities owned on the Closing Date by all holders of Parity Securities that are participating in the offering.

(c) The Piggyback Registration rights set forth in this Section 2.3 shall be available to the Holders only in the event that the Company is unable to file the Common Shares Registration Statement or a Fleet Growth Registration Statement in accordance with Section 2.1 or 2.2, respectively, and shall terminate with respect to each of Section 2.1 and Section 2.2 upon the earlier of (i) when the Common Shares and any Fleet Growth Shares, as applicable, have been registered under the Securities Act, and (ii) when the Common Shares and any Fleet Growth Shares, as applicable, have been, or are eligible to be, sold pursuant to Rule 144 (or any similar provision then in force) without restriction under the Securities Act.

2.4 Expenses of Registration.

Except as specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or compliance hereunder shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the aggregate offering or sale price of the securities registered.

2.5 Obligations of the Company.

Whenever required to effect the registration of any Registrable Securities under Section 2.1 or 2.2, the Company shall, as expeditiously as reasonably practicable (but in no event more than 60 days following such requirement):

(a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use all commercially reasonable efforts to cause such registration statement to become effective, or prepare and file with the SEC a prospectus supplement with respect to such Registrable Securities pursuant to an effective registration statement.

Page 6

(b) Prepare and file with the SEC such amendments and supplements to the applicable registration statement and the prospectus or prospectus supplement used in connection with such registration statement 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 period set forth in Section 2.1 or 2.2, as applicable.

(c) Furnish to the Holders such number of copies of the applicable registration statement and each such amendment and supplement thereto (including in each case all exhibits) and of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them.

(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 the Holders, to keep such registration or qualification in effect for so long as such registration statement remains in effect, and to take any other action which may be reasonably necessary to enable such seller to consummate the disposition in such jurisdictions of the securities owned by such Holder; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions.

(e) Enter customary agreements (including if the method of distribution is by means of an underwriting, an underwriting agreement in customary form with the managing underwriter(s) of such offering) and take such other actions (including participating in and making documents available for the due diligence review of underwriters if the method of distribution is by means of an underwriting) as are reasonably required in order to facilitate the disposition of such Registrable Securities. Each Holder participating in such underwriting shall also enter into and perform its obligations under such underwriting agreement.

(f) Notify each Holder at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the applicable prospectus, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing.

(g) Use its commercially reasonable efforts to furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of outside legal counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, and (ii) a letter dated as of such date, from the independent registered public accountants of the Company, in form and substance as is customarily given by independent registered public accountants to underwriters in an underwritten public offering addressed to the underwriters.

Page 7

(i) when any registration statement filed pursuant to Section 2.1 or 2.2 or any amendment thereto has been filed with the SEC and when such registration statement or any post-effective amendment thereto has become effective;

(ii) of any request by the SEC for amendments or supplements to any registration statement filed pursuant to Section 2.1 or 2.2 or the prospectus included therein or for additional information;

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of any registration statement filed pursuant to Section 2.1 or 2.2 or the initiation of any proceedings for that purpose;

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Common Shares or the Fleet Growth Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v) of the occurrence of any event that requires the Company to make changes in any effective registration statement filed pursuant to Section 2.1 or 2.2 or the prospectus related to the registration statement in order to make the statements therein not misleading (which notice shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made).

(i) Use its commercially reasonable efforts to prevent the issuance or obtain the withdrawal of any order suspending the effectiveness of any registration statement referred to in Section 2.5(h)(i) within a reasonable time.

(j) Upon the occurrence of any event contemplated by Section 2.5(h)(iii) above, prepare a post-effective amendment to such registration statement or a supplement to the related prospectus or file any other required document so that, as thereafter delivered to the Holders, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with Section 2.5(h)(iii) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Holders shall suspend use of such prospectus and use their commercially reasonable efforts to return to the Company all copies of such prospectus then in such Holder’s possession.

(k) Use commercially reasonable efforts to procure the cooperation of the Company’s transfer agent in settling any offering or sale of Registrable Securities, including with respect to the transfer of physical stock certificates into book-entry form in accordance with any procedures reasonably requested by the Holders or the underwriters.

2.6 Suspension of Sales.

During any Scheduled Black-out Period or upon receipt of written notice from the Company that a registration statement, prospectus or prospectus supplement contains or may contain an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that circumstances exist that make inadvisable use of such registration statement, prospectus or prospectus supplement, each Holder of Registrable Securities shall forthwith discontinue disposition of Registrable Securities until termination of such Scheduled Black-Out Period or until the Holder has received copies of a supplemented or amended prospectus or prospectus supplement, or until such Shareholder is advised in writing by the Company that the use of the prospectus and, if applicable, prospectus supplement may be resumed, and, if so directed by the Company, such Holder shall deliver to the Company all copies then in such Holder’s possession, of the prospectus and, if applicable, prospectus supplement covering such Registrable Securities current at the time of receipt of such notice.

2.7 Delay of Registration; Furnishing Information.

(a) No Holder shall use any free writing prospectus (as defined in Rule 405 under the Securities Act) in connection with the sale of Registrable Securities without the prior written consent of the Company.

(b) It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 2.1 or 2.2 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities.

2.8 Indemnification.

(a) The Company agrees to indemnify each Holder and, if a Holder is a person other than an individual, such Holder’s officers, directors, employees, agents, representatives and Affiliates, and each person or entity, if any, that controls a Holder within the meaning of the Securities Act (each, a “Holder Indemnitee”), against any and all losses, claims, damages, actions, liabilities, costs and expenses (including without limitation reasonable fees, expenses and disbursements of attorneys and other professionals), joint or several, arising out of or based upon any untrue or alleged untrue statement of material fact contained in any registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto or contained in any free writing prospectus (as such term is defined in Rule 405 under the Securities Act) prepared by the Company or authorized by it in writing for use by such Holder (or any amendment or supplement thereto); or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, that the Company shall not be liable to such Holder Indemnitee in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, including

Page 9

any such preliminary prospectus or final prospectus contained therein or any such amendments or supplements thereto or contained in any free writing prospectus (as such term is defined in Rule 405 under the Securities Act) prepared by the Company or authorized by it in writing for use by such Holder (or any amendment or supplement thereto), in reliance upon and in conformity with information regarding such Holder Indemnitee or its plan of distribution or ownership interests which was furnished to the Company for use in connection with such registration statement, including any such preliminary prospectus or final prospectus contained therein or any such amendments or supplements thereto, (ii) offers or sales effected by or on behalf such Holder Indemnitee “by means of” (as defined in Securities Act Rule 159A) a “free writing prospectus” (as defined in Securities Act Rule 405) that was not authorized in writing by the Company, or (iii) the failure of any Holder to deliver or make available to a purchaser of Registrable Securities, a copy of any registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto (if the same was required by applicable law to be delivered or made available), provided that the Company shall have delivered to such Holder such registration statement, including such preliminary prospectus or final prospectus contained therein and any amendments or supplements thereto.

(b) If the indemnification provided for in Section 2.8(a) is unavailable to a Holder Indemnitee with respect to any losses, claims, damages, actions, liabilities, costs or expenses referred to therein or is insufficient to hold the Holder Indemnitee harmless as contemplated therein, then the Company, in lieu of indemnifying such Holder Indemnitee, shall contribute to the amount paid or payable by such Holder Indemnitee as a result of such losses, claims, damages, actions, liabilities, costs or expenses in such proportion as is appropriate to reflect the relative fault of the Holder Indemnitee, on the one hand, and the Company, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, actions, liabilities, costs or expenses as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Holder Indemnitee, on the other hand, shall be determined by reference to, among other factors, whether the untrue or alleged untrue statement of a material fact or omission to state a material fact relates to information supplied by the Company or by the Holder Indemnitee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; the Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 2.8(b) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 2.8(a). No Holder Indemnitee guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from the Company if the Company was not guilty of such fraudulent misrepresentation.

2.10 “Market Stand-Off” Agreement; Agreement to Furnish Information.

Each Shareholder and each Holder hereby agree that the Shareholder and/or Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to, any Common Shares or any Fleet Growth Shares (or other securities of the Company) held by the Shareholder or Holder (other than those included in the registration) for a period (the “Restricted Period”) specified by the representatives of the underwriters of Class A Common Shares (or other securities of the Company) not to exceed ten (10) days prior and ninety (90) days following any registered sale by the Company.

(a) make and keep public information available, as those terms are understood and defined in Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of this Agreement;
