ARTICLE 2
REGISTRATION RIGHTS

Section 2.01.  Demand Registration . (a) Subject to Section 2.03, if the Company shall receive a request from Monarch (in this case, Monarch shall be referred to herein as the “ Requesting Shareholder ”) that the Company effect the registration under the Securities Act of all or any portion of the Requesting Shareholder’s Registrable Securities, and specifying the intended method of disposition thereof, then the Company shall promptly give notice of such requested registration (each such request shall be referred to herein as a “ Demand Registration ”) at least 5 Business Days prior to the anticipated filing date of the registration statement relating to such Demand Registration to any other Shareholders (if any) and thereupon shall use its commercially reasonable efforts to effect, as expeditiously as possible, the registration under the Securities Act of:

(i)              all Registrable Securities for which the Requesting Shareholder has requested registration under this Section 2.01, and

(ii)           subject to the restrictions set forth in Sections 2.01(e) and 2.02, all other Registrable Securities of the same class as those requested to be registered by the Requesting Shareholder that any Shareholders (all such Shareholders, together with the Requesting Shareholder, the “ Registering Shareholders ”) have requested the Company to register pursuant to Section 2.02, by request received by the Company within 3 Business Days after such Shareholders receive the Company’s notice of the Demand Registration,

all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered, provided that, the Company shall not be obligated to effect a Demand Registration unless the aggregate proceeds expected to be received from the sale of the Registrable Securities requested to be included in such Demand Registration equals or exceeds $35,000,000 or such lesser amount that constitutes all of the Requesting Shareholder’s Registrable Securities.  In no event shall the Company be required to effect more than one Demand Registration hereunder within any six-month period or more than three Demand Registrations in the aggregate.

(b)                    Promptly after the expiration of the 3-Business Day-period referred to in Section 2.01(a)(ii), the Company will notify all Registering Shareholders of the

5

identities of the other Registering Shareholders and the number of shares of Registrable Securities requested to be included therein.  At any time prior to the effective date of the registration statement relating to such registration, the Requesting Shareholder may revoke such request, without liability to any of the other Registering Shareholders, by providing a notice to the Company revoking such request.  A request, so revoked, shall be considered to be a Demand Registration unless such revocation arose out of the fault of the Company.

(c)                     The Company shall pay all Registration Expenses in connection with each Demand Registration.

(d)                    A Demand Registration shall not be deemed to have occurred unless the registration statement relating thereto (i) has become effective under the Securities Act and (ii) has remained effective for a period of at least 30 days (or such shorter period in which all Registrable Securities of the Registering Shareholders included in such registration have actually been sold thereunder), provided that such registration statement shall not be considered a Demand Registration if, after such registration statement becomes effective, (1) such registration statement is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court and (2) less than 75% of the Registrable Securities included in such registration statement have been sold thereunder.

(e)                     If a Demand Registration involves an underwritten Public Offering and the managing underwriter advises the Company and the Requesting Shareholder that, in its view, the number of shares of Registrable Securities requested to be included in such registration (including any securities that the Company proposes to be included that are not Registrable Securities) exceeds the largest number of shares that can be sold without having an adverse effect on such offering, including the price at which such shares can be sold (the “ Maximum Offering Size ”), the Company shall include in such registration, in the priority listed below, up to the Maximum Offering Size:

(i)          first, all Registrable Securities requested to be registered by the Requesting Shareholder (allocated, if there is more than one Requesting Shareholder and if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such entities on the basis of the relative number of Registrable Securities so requested to be included in such registration by each),

(ii)       second, all Registrable Securities requested to be included in such registration by any other Registering Shareholder (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such other Shareholders on the basis of the relative number of

6

Registrable Securities so requested to be included in such registration by each such Shareholder), and

(iii)                  third, any securities proposed to be registered by the Company or for the account of any other third party.

(f)                      Upon notice to the Requesting Shareholder, the Company may postpone effecting a registration pursuant to this Section 2.01 (a) at any time during its regular quarterly blackouts applicable to insiders (“ Quarterly Blackouts ”) and (b) at any other time, for a reasonable time specified in the notice but not exceeding 90 days in the aggregate during any twelve month period in the case of this clause (b) (which period may not be extended or renewed), in each case if either of the following conditions is present: (i) the Company reasonably determines that effecting the registration would materially and adversely affect an offering of securities of the Company the preparation of which had then been commenced or (ii) the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company reasonably believes would not be in the best interests of the Company.

Section 2.02.  Piggyback Registration .  (a) If the Company proposes to register any Class A Common Shares under the Securities Act (other than (i) a Shelf Registration, which will be subject to the provisions of Section 2.03); provided that any Underwritten Takedown will be subject to this section or (ii) a registration on Form S-8, S-4 or F-4, or any successor forms, relating to Class A Common Shares issuable upon exercise of employee stock options or in connection with any employee benefit or similar plan of the Company or in connection with a direct or indirect acquisition by the Company of another Person), whether or not for sale for its own account, the Company shall each such time give prompt notice at least 5 Business Days prior to the anticipated filing date of the registration statement relating to such registration to each Shareholder, which notice shall set forth such Shareholder’s rights under this Section 2.02 and shall offer such Shareholder the opportunity to include in such registration statement the number of Registrable Securities of the same class or series as those proposed to be registered as each such Shareholder may request (a “ Piggyback Registration ”), subject to the provisions of Section 2.02(b).  Upon the request of any such Shareholder made within 3 Business Days after the receipt of notice from the Company (which request shall specify the number of Registrable Securities intended to be registered by such Shareholder), the Company shall use commercially reasonable efforts to effect the registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by all such Shareholders, to the extent requisite to permit the disposition of the Registrable Securities so to be registered, provided that (i) if such registration involves an underwritten Public Offering, all such Shareholders requesting to be included in the Company’s registration must sell their Registrable Securities to the underwriters selected as provided in Section 2.05(f)(i) on the same terms and

7

conditions as apply to the Company or the Registering Shareholders, as applicable, and (ii) if, at any time after giving notice of its intention to register any Class A Common Shares pursuant to this Section 2.02(a) 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 such securities, the Company shall give notice to all such Shareholders and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration.  No registration effected under this Section 2.02 shall relieve the Company of its obligations to effect a Demand Registration to the extent required by Section 2.01 or a Shelf Registration to the extent required by Section 2.03.  The Company shall pay all Registration Expenses in connection with each Piggyback Registration.

(b)                    If a Piggyback Registration involves an underwritten Public Offering (other than any Demand Registration, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.01(e) shall apply) and the managing underwriter advises the Company that, in its view, the number of Shares that the Company and such Shareholders intend to include in such registration exceeds the Maximum Offering Size, the Company shall include in such registration, in the following priority, up to the Maximum Offering Size:

(i)                                                first, so much of the Class A Common Shares proposed to be registered for the account of the Company or the person for whom such registration is being undertaken as would not cause the offering to exceed the Maximum Offering Size,

(ii)                                             second, all Registrable Securities requested to be included in such registration by any Shareholders pursuant to Section 2.02 and other holders of Class A Common Shares that have piggyback registration rights in connection therewith (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Shareholders on the basis of the relative number of shares of Registrable Securities so requested to be included in such registration by each), and

(iii)                                          third, any securities proposed to be registered for the account of any other Persons with such priorities among them as the Company shall determine.

Section 2.03.  Shelf Registration .  (a) At any time when the Company is eligible to use Form S-3, Monarch may request the Company to effect a registration of the Registrable Securities under a Registration Statement pursuant to Rule 415 under the Securities Act (or any successor rule) (a “ Shelf Registration ”).  The Company shall only be required to effectuate one Public Offering from such Shelf Registration (an “ Underwritten Takedown ”) within any six-month period, which offering shall be deemed a Demand Registration,

8

and may only be requested by Monarch.  The provisions of Section 2.01 shall apply mutatis mutandis to such Underwritten Takedown, with references to “filing of the registration statement” or “effective date” being deemed references to filing of a prospectus or supplement for such offering and references to “registration” being deemed references to the offering; provided that Registering Shareholders shall only include Shareholders whose Registrable Securities are included in such Shelf Registration or may be included therein without the need for an amendment to such Shelf Registration (other than an automatically effective amendment).  So long as the Shelf Registration is effective, no Shareholder may request any Demand Registration pursuant to Section 2.01.

(b)                    If the Company shall receive a request from Monarch that the Company effect a Shelf Registration, then the Company shall promptly give notice of such requested registration at least 5 Business Days prior to the anticipated filing date of the registration statement relating to such Shelf Registration to the other Shareholders and thereupon shall use its commercially reasonable efforts to effect, as expeditiously as possible, the registration under the Securities Act of:

(i)                                                all Registrable Securities for which Monarch have requested registration under this section, and

(ii)                                             all other Registrable Securities of the same class as those requested to be registered by the Requesting Shareholder that any Shareholders have requested the Company to register by request received by the Company within 3 Business Days after such Shareholders receive the Company’s notice of the Shelf Registration,

all to the extent necessary to permit the registration of the Registrable Securities so to be registered on such Shelf Registration.

(c)                     The Company shall pay all Registration Expenses in connection with each Shelf Registration.

(d)                    At any time prior to the effective date of the registration statement relating to such Shelf Registration, Monarch may revoke such request, without liability to any of the other Registering Shareholders, by providing a notice to the Company revoking such request.

(e)                     The Company shall use its commercially reasonable efforts to keep such Shelf Registration Statement continuously effective under the Securities Act in order to permit the prospectus forming a part thereof to be usable by the Shareholders until the date as of which there are no Registrable Securities outstanding or the Company is no longer eligible to use Form S-3 (such period, the “ Shelf Period ”).

9

(f)                      Upon notice to the Requesting Shareholder, the Company may suspend use of the Shelf Registration Statement (a “ Suspension Event ”)  pursuant to this Section 2.03 (a) at any time during Quarterly Blackouts and (b) at any other time, for a reasonable time specified in the notice but not exceeding 90 days in the aggregate during any period of twelve consecutive months in the case of this clause (b) (which period may not be extended or renewed), in each case if either of the following conditions is present: (i) the Company determines that effecting the registration would materially and adversely affect an offering of securities of such Company the preparation of which had then been commenced or (ii) the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company reasonably believes would not be in the best interests of the Company.

Section 2.04.  Lock-Up Agreements .  If any registration of Registrable Securities shall be effected in connection with a Public Offering if requested by the managing underwriter or any other public offering of Class A Common Stock by the Company, neither the Company nor any Shareholder shall effect any public sale or distribution, including any sale pursuant to Rule 144, of any Class A Common Shares or other security of the Company (except as part of such Public Offering) during the period beginning 5 days prior to the effective date of the applicable registration statement or, in the case of a Shelf Registration, 5 days prior to launch of the offering or such later date when the Shareholder receives notice thereof and ending upon the earlier of (i) such time as the Company and the lead managing underwriter shall agree and (ii) 90 days after the pricing thereof (such period, the “ Lock-Up Period ” for the applicable registration statement). In addition, in connection with any Public Offering, the Company and the Shareholders will execute any lock-up agreement reasonably requested by the managing underwriter for a period not exceeding the Lock-Up Period.

Section 2.05.  Registration Procedures .  Whenever Shareholders request that any Registrable Securities be registered pursuant to Section 2.01, 2.02, or 2.03 subject to the provisions of such Sections, the Company shall use commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable, and, in connection with any such request:

(a)                    The Company shall prepare and file with the SEC a registration statement on any form for which the Company then qualifies or that counsel for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use commercially reasonable efforts to cause such filed registration statement to become and remain effective for a period of not less than 30 days, or in the case of a Shelf Registration, until such time as all of the Registrable Securities of the Shareholders included in such registration statement shall have actually been sold thereunder or cease to be Registrable

10

Securities).  Any such registration statement shall be an automatically effective registration statement to the extent permitted by the SEC’s rules and regulations.

(b)                    Prior to filing a registration statement or prospectus or any amendment or supplement thereto (other than any report filed pursuant to the Exchange Act that is incorporated by reference therein), the Company shall, if requested, furnish to each participating Shareholder and each underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed, and thereafter the Company shall furnish to such Shareholder and underwriter, if any, such number of copies of such registration statement, each amendment and supplement thereto (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 any summary prospectus) and any other prospectus filed under Rule 424, Rule 430A, Rule 430B or Rule 430C under the Securities Act and such other documents as such Shareholder or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Shareholder.

(c)                     After the filing of the registration statement, the Company shall (i) cause the related prospectus to be supplemented by any required prospectus supplement, and, as so supplemented, to be filed pursuant to Rule 424 under the Securities Act, (ii)comply with the provisions of the Securities Act with respect to the disposition of all Securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the Shareholders thereof set forth in such registration statement or supplement to such prospectus and (iii) promptly notify each Shareholder holding Registrable Securities covered by such registration statement of any stop order issued or threatened by the SEC or any state securities commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered.

(d)                    The Company shall use commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by such registration statement under such other securities or “blue sky” laws of such jurisdictions in the United States as any Registering Shareholder holding such Registrable Securities reasonably (in light of such Shareholder’s intended plan of distribution) requests and (ii) cause such Registrable Securities to be registered with or approved by such other governmental agencies or 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 reasonably necessary or advisable to enable such Shareholder to consummate the disposition of the Registrable Securities owned by such Shareholder, provided that the Company shall not be required to (A)  qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 2.05(d), (B) subject itself to taxation in any such jurisdiction or (C)  consent to general service of process in any such jurisdiction.

(f)                      (i) Monarch shall have the right to select an underwriter or underwriters in connection with any Public Offering resulting from its exercise of a Demand Registration (including any Underwritten Takedown), which underwriter shall be reasonably acceptable to the Company and (ii) the Company shall select an underwriter or underwriters in connection with any other Public Offering.  In connection with any Public Offering, the Company shall enter into customary agreements (including an underwriting agreement in customary form) and take such all other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities in any such Public Offering.

(g)                     In any Demand Registration or Public Offering, upon execution of confidentiality agreements in form and substance reasonably satisfactory to the Company, the Company shall make available for inspection by any Shareholder and any underwriter participating in any disposition pursuant to a registration statement being filed by the Company pursuant to this Section 2.05 and any attorney, accountant or other professional retained by any such Shareholder or underwriter (collectively, the “ Inspectors ”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “ Records ”) as shall be reasonably necessary or desirable to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any Inspectors in connection with such registration statement.  Each Shareholder agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it or its Affiliates as the basis for any market transactions in the Class A Common Shares unless and until such information is made generally available to the public.  Each Shareholder further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, it shall give notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential.

(j)                       The Company may require each Shareholder promptly to furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration.

(k)                    Each Shareholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.05(e) or any Suspension Event, such Shareholder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Shareholder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.05(e) or the end of the Suspension Event, and, if so directed by the Company, such Shareholder shall deliver to the Company all copies, other than any permanent file copies then in such Shareholder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.  If the Company shall give such notice under Section 2.05(e), the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 2.05(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.05(e) to the date when the Company shall make available to such Shareholder a prospectus supplemented or amended to conform with the requirements of Section 2.05(e).

substantially the same basis as that of the indemnification of the Shareholders provided in this Section 3.01.

Section 3.02.  Indemnification by Participating Shareholders .  Each Shareholder holding Registrable Securities included in any registration statement agrees, severally but not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Shareholder, but only with respect to information furnished in writing by such Shareholder or on such Shareholder’s behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto, or any preliminary prospectus or free-writing prospectus.  Each such Shareholder also agrees to indemnify and hold harmless underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Company provided in this Section 3.02.  As a condition to including Registrable Securities in any registration statement filed in accordance with Article 2, the Company may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by underwriters with respect to similar securities.  No Shareholder shall be liable under this Section 3.02 for any Damages in excess of the net proceeds realized by such Shareholder in the sale of Registrable Securities of such Shareholder to which such Damages relate.

Section 3.03.  Conduct of Indemnification Proceedings .  If any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to this Article 3, such Person (an “ Indemnified Party ”) shall promptly notify the Person against whom such indemnity may be sought (the “ Indemnifying Party ”) in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses, provided that the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify.  In any such proceeding, any Indemnified Party 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 Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  It is understood that, in connection with any proceeding

15

or related proceedings in the same jurisdiction, the Indemnifying Party shall not be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred.  In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties.  The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment.  Without the prior written consent of the Indemnified Party, no Indemnifying Party shall effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding.

Section 3.04.  Contribution .  If the indemnification provided for in this Article 3 is unavailable to the Indemnified Parties in respect of any Damages, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Damages (i) as between the Company and the Shareholders holding Registrable Securities covered by a registration statement on the one hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and such Shareholders on the one hand and the underwriters on the other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and such Shareholders on the one hand and of such underwriters on the other in connection with the statements or omissions that resulted in such Damages, as well as any other relevant equitable considerations and (ii) as between the Company on the one hand and each such Shareholder on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each such Shareholder in connection with such statements or omissions, as well as any other relevant equitable considerations.  The relative benefits received by the Company and such Shareholders on the one hand and such underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and such Shareholders bear to the total underwriting discounts and commissions received by such underwriters, in each case as set forth in the table on the cover page of the prospectus.  The relative fault of the Company and such Shareholders on the one hand and of such underwriters on the other shall be determined by reference to, among other things,

16

whether the untrue or 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 and such Shareholders or by such underwriters.  The relative fault of the Company on the one hand and of each such Shareholder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Shareholders agree that it would not be just and equitable if contribution pursuant to this Section 3.03 were determined by pro rata allocation (even if the underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph.  The amount paid or payable by an Indemnified Party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 3.03, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any Damages that such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Shareholder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Shareholder were offered to the public (less underwriters’ discounts and commissions) exceeds the amount of any Damages that such Shareholder 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.  Each Shareholder’s obligation to contribute pursuant to this Section 3.03 is several in the proportion that the proceeds of the offering received by such Shareholder bears to the total proceeds of the offering received by all such Shareholders and not joint.

Section 3.05.  Participation in Public Offering .  No Shareholder may participate in any Public Offering hereunder unless such Shareholder (a) agrees to sell such Shareholder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably

17

required under the terms of such underwriting arrangements and the provisions of this Agreement in respect of registration rights.

Section 3.06.  Cooperation by the Company .  If any Shareholder shall transfer any Registrable Securities pursuant to Rule 144, the Company shall cooperate, to the extent commercially reasonable, with such Shareholder and shall provide to such Shareholder such information reasonably required to comply with Rule 144 as such Shareholder shall reasonably request.
