ARTICLE 2 CORPORATE GOVERNANCE Section 2.01. Composition of the Board. (a) The Board Generally. The Board shall be comprised of such number of independent directors as may be required, from time to time, by applicable securities law and/or applicable Nasdaq (or stock exchange) regulations (collectively, the "Independent Directors") and such additional directors (collectively, the "Director Designees") as may be designated by the MSCP Funds acting as a group (collectively, the "MSCP Directors") and the Somerset Group Members acting as a group (collectively, the "Somerset Directors"), in accordance with the following provisions. Each of the MSCP Funds acting as a group, on the one hand, and the Somerset Group Members acting as a group (the "Somerset Group"), on the other hand, shall be entitled to designate such maximum number of Director Designees (rounded up or down, as the case may be, to the closest whole number) as shall be equal to the Total Number of Director Designees (as hereinafter defined) multiplied by a fraction, the numerator of which is the sum of the UDCL Proportionate Security Amount of the MSCP Funds or the Somerset Group (as the case may be) and any other Company Securities directly owned by any member of such MSCP Funds or Somerset Group, as the case may be (that is, exclusive of Company Securities owned by UDCL), and the denominator of which is the sum of the aggregate UDCL Proportionate Security Amount of the MSCP Funds and the Somerset Group plus all Company Securities directly owned by any members of the MSCP Funds and/or the Somerset Group (other than the shares of Company Securities owned by UDCL). As used herein, the term Total Number of Director Designees shall mean the total number of directors as shall constitute the entire Board of Directors of the Company at any given time in accordance with the Bylaws of the Company, less the number of Independent Directors; provided, however, that in the event that either the MSCP Funds on the one hand, or the Somerset Group, on the other hand, chooses not to fill its maximum number of Director Designees at any given time for any reason, the Total Number of Director Designees shall mean the total number of directors as would constitute the entire Board of Directors if the Company were to increase the number of directors as shall constitute the entire Board of Directors to such number as would be required to maintain the proportionate number of Director Designees as between the MSCP Funds on the one hand and the Somerset Group on the other hand without requiring that any incumbent Director Designee of either the MSCP Funds on the one hand, or the Somerset Group on the other hand, resign his position as a 10  director of the Company, it being expressly agreed that neither the MSCP Funds on the one hand nor the Somerset Group on the other hand, shall be deemed to have waived or forfeited its right to nominate a proportionate number of Director Designees because it may choose to have less than its maximum proportionate representation on the Board of Directors at any time. In the event that any group shall later determine to exercise its rights hereunder to have the maximum representation possible on the Board of Directors, and the Company, the Board of Directors and/or the stockholder groups shall take such action as may be deemed necessary, advisable or appropriate to increase the number of directors as shall constitute the entire Board of Directors and facilitate the appointment or election of the new Director Designees, such increase in the Board shall be done in accordance with the provisions contained in the Company's Bylaws pertaining to the staggered or classified Board. To the extent that the specification of the class of the new directorship(s) is not mandated by the Company's Bylaws, the group entitled to the appointment of the additional Director Designee(s) shall be entitled to specify the class or classes of the new directorship(s). By way of example, on the date hereof (i) UDCL owns 13,162,936 shares of Company Securities, (ii) the members of the Somerset Group directly own an additional 2,771,145 shares of Company Securities, (iii) the UDCL Proportionate Security Amount of the MSCP Funds is 9,799,654 and the UDCL Proportionate Security Amount of the Somerset Group is 3,363,282. Therefore, based upon the respective proportionate ownership of Company Securities by the MSCP Funds on the one hand and the Somerset Group on the other hand, the MSCP Funds would be entitled to designate 61.5% of Total Number of Director Designees and the Somerset Group would be entitled to designate 38.5% of the Total Number of Director Designees. At present, the total number of directors as constitutes the entire Board of Directors is six, of which one member (Thomas H. O'Neill, Jr.) has been designated by the Board as an Independent Director, four members are MSCP Directors (Messrs. Harmon, Hoffen, Moon and Myers) and one member is a Somerset Director (William R. Ziegler). Based upon the relative proportionate ownership of Company Securities by the MSCP Funds, on the one hand, and the Somerset Group, on the other hand, and without taking into account the proviso included in the definition of Total Number of Director Designees, the MSCP Funds would be entitled to designate three of the total five Director Designees and the Somerset Group would be entitled to designate two of the total five Director Designees. However, after giving effect to the proviso contained in the definition of Total Number of Director Designees, since the MSCP Funds already has four Director Designees, the Somerset Group has the right (but not the obligation), exercisable at any time in its sole option, to elect to increase the size of the whole Board of Directors to eight Directors, so that the Total Number of Director Designees will be seven, of which three will be deemed Somerset Directors. In 11  any such case, the members of the MSCP Funds will take such action as may be deemed necessary, advisable or appropriate to facilitate such increase in the size of the Board and the election of two Somerset Designees to fill the vacancies caused by such increase. In the event that the proportionate ownership of Company Securities by either the MSCP Funds or the Somerset Group (as the case may be) shall decrease relative to the aggregate ownership of Company Securities by the other group, and such decrease is as a result of sale or other disposition of Company Securities by such group, and the amount of such decrease is significant enough to change the number of Director Designees that such group would be entitled to under the formula specified above for calculating rights to Director Designees, then within 60 days of the date of such sale or other disposition of the Company Securities the MSCP Funds or the Somerset Group (as the case may be) shall cause one or more Director Designees of such group (as may be required to restore the relative proportion of Director Designees of the two groups) to resign his position (s) as a director and/or Committee member and such group shall not be entitled to nominate any replacement Director Designee therefor. If shall be up to the group that is losing a Director Designee(s) to determine, in its sole discretion, the specific Director Designee(s) that will resign. Notwithstanding the foregoing, for so long as either the MSCP Funds, on the one hand, or the Somerset Group, on the other hand, own any Company Securities and are bound by the terms of this Agreement, the number of Director Designees that such group would be entitled to designate shall not be reduced below one Director Designee. Board Committees. The provisions contained above in this Section 2.01 with respect to the composition of the full Board of Directors of the Company, inclusive of any independent director requirements under applicable securities laws and/or applicable regulation of Nasdaq (or any securities exchange on which any equity securities of the Company may then be listed or admitted for trading) and the relative rights of the each of the MSCP Funds and the Somerset Group to designate members to the Board of Directors, shall apply mutatis mutandis to any and all committees of the Board of Directors. (b) Voting Agreement. The MSCP Funds (in their capacity as controlling members of UDCL) and each Somerset Group Member agrees that, if at any time it is then entitled to vote for the election of directors to the Board or any Board committee, it shall vote its Shares or execute proxies or written consents, as the case may be, and take all other necessary action (including causing the Company to call a special meeting of shareholders) in order to ensure that the composition of the Board and any Board committee is as set forth in this Section 2.01. In furtherance and not in limitation of the foregoing, each of the MSCP Funds (on behalf of UDCL and/or on its own behalf, as the case may be) 12  and each of the Somerset Group Members shall execute and deliver such consents, proxies, certificates, instruments and other documents as shall be necessary or advisable to carry out and make effective the voting agreement set forth above, including, without limitation, the execution and delivery contemporaneously herewith of an irrevocable proxy, coupled with an interest (individually, a "Proxy" and collectively, the "Proxies"), substantially in the form of Exhibit C-1 attached hereto (in the case of the MSCP Funds) or Exhibit C-2 attached hereto (in the case of the Somerset Group Members). Notwithstanding any other provisions contained herein or in any Proxy to the contrary, any proxy created hereunder shall remain in effect for the full term of the Shareholders Agreement and shall terminate upon the termination of this Shareholders Agreement, unless otherwise required by law. It is the intention of the parties hereto that this Agreement comply in all respects with the requirements of Sections 218(c) and 212 of the General Corporation Law of the State of Delaware governing voting agreements among shareholders and irrevocable proxies, respectively. If any provision of this Agreement or any proxy delivered pursuant hereto, including, without limitation, the Proxies, or the application of such provision to any person or entity or circumstance, shall be held invalid, the remainder of this Agreement and of any such proxy, and the application of any such provision to any person or circumstance other than those to which it is held invalid, shall not be affected thereby. (c) Company Covenant.

Section 3.06. No Indirect Transfers. No Somerset Group Member that is not a natural person shall permit any Transfers, directly or indirectly, of its equity interests to any Person, other than to a Permitted Transferee, if the principal purpose of such transaction is to effect a Transfer of any Company Securities that circumvents the transfer restrictions contained elsewhere in this Agreement.

ARTICLE 4 TAG-ALONG RIGHTS Section 4.01. Tag-Along Rights. Subject to Sections 4.01(i) and 4.02, if, at any time, (i) UDCL proposes to Transfer to a Third Party, in a transaction otherwise permitted by Article 3, any class of Company Securities and the MSCP Funds' UDCL Proportionate Security Amount included in such Transfer equals or exceeds the Tag Threshold or (ii) one or more Somerset Group Members propose to Transfer to a Third Party (other than to another Somerset Group Member or Permitted Transferee of a Somerset Group Member), in a transaction otherwise permitted by Article 3, a number of any class of Company Securities that equals or exceeds the Tag Threshold, in each case in a single transaction or in a series of related transactions (a "TAG-ALONG SALE," and UDCL or such Somerset Group Members (acting as a group), as applicable, the "TAG-ALONG SELLER"), (i) the Tag-Along Seller (or Tag-Along Sellers) shall, if applicable), provide each other Shareholder (the "TAG-ALONG OFFEREE") notice of the terms and conditions of such proposed Transfer ("TAG-ALONG NOTICE") and offer each Tag-Along Offeree the opportunity to participate in such Transfer in accordance with this Section 4.01, and (ii) each Tag-Along Offeree may elect, at its option, to participate in the proposed Transfer in accordance with this Section 4.01 (each Shareholder so electing, a "TAGGING PERSON"). Any Transfer of Company Securities by any Somerset Group Member that occurs within six months of any other Transfer of Company Securities by the same or any other Somerset Group Member shall be conclusively deemed to be related to such previous transaction for the purposes of this Section 4.01, and any Transfer of Company Securities by UDCL that occurs within six months of any other Transfer of Company Securities by UDCL shall be conclusively deemed to be related to such previous transaction for the purposes of this Section 4.01. (b) The Tag-Along Notice shall identify the maximum number and class of Company Securities proposed to be sold by the Tag-Along Seller and all other Company Securities subject to the offer ("TAG-ALONG OFFER"), the consideration 19  for which the Transfer is proposed to be made, and all other material terms and conditions of the Tag-Along Offer, including the form of the proposed agreement, if any, and a firm offer by the proposed Transferee to purchase Company Securities from the Tag-Along Seller, in accordance with this Section 4.01. (c) From the date of its receipt of the Tag-Along Notice, each Tag-Along Offeree shall have the right (a "TAG-ALONG RIGHT"), exercisable by notice ("TAG-ALONG RESPONSE NOTICE") given to the Tag-Along Seller within 15 Business Days after its receipt of the Tag-Along Notice (the "TAG-ALONG NOTICE PERIOD"), to request that the Tag-Along Seller include in the proposed Transfer the number of Company Securities held by such Tagging Person as is specified in the Tag-Along Response Notice; provided that each Tagging Person shall be entitled to include in the Tag-Along Sale only its Tag-Along Portion of Company Securities, and the Tag-Along Seller shall be entitled to include up to the number of Company Securities proposed to be Transferred by the Tag-Along Seller as set forth in the Tag-Along Notice (reduced, to the extent necessary, so that each Tagging Person shall be able to include its Tag-Along Portion) and such additional Company Securities as permitted by Section 4.01(g). Each Tag-Along Response Notice shall include wire transfer instructions for payment of the purchase price for the Company Securities to be sold in such Tag-Along Sale. Each Tagging Person that exercises its Tag-Along Rights hereunder shall deliver to the Tag-Along Seller, with its Tag-Along Response Notice, the certificate or certificates representing the Company Securities of such Tagging Person to be included in the Tag-Along Sale, together with a limited power-of-attorney authorizing the Tag-Along Seller to Transfer such Company Securities on the terms set forth in the Tag-Along Notice. Delivery of the Tag-Along Response Notice with such certificate or certificates and limited power-of-attorney shall constitute an irrevocable acceptance of the Tag-Along Offer by such Tagging Persons. (d) If, at the end of a 120-day period after such delivery of such Tag-Along Response Notice (which 120-day period shall be extended if any of the transactions contemplated by the Tag-Along Offer are subject to regulatory approval until the expiration of five Business Days after all such approvals have been received, but in no event later than 180 days following receipt of the Tag-Along Response Notice by the Tag-Along Seller), the Tag-Along Seller has not completed the Transfer of all such Company Securities on substantially the same terms and conditions set forth in the Tag-Along Notice, the Tag-Along Seller shall (i) return to each Tagging Person the limited power-of-attorney (and all copies thereof) together with all certificates representing the Company Securities that such Tagging Person delivered for Transfer pursuant to this Section 4.01(a) and any other documents in the possession of the Tag-Along Seller executed by the Tagging Persons in connection with the proposed Tag-Along Sale, and (ii) not 20  conduct any Transfer of Company Securities subject to this Section without again complying with this Section. (e) Concurrently with the consummation of the Tag-Along Sale, the Tag-Along Seller shall (i) notify the Tagging Persons thereof, (ii) remit to the Tagging Persons the total consideration for the Company Securities of the Tagging Persons Transferred pursuant thereto, with the cash portion of the purchase price paid by wire transfer of immediately available funds in accordance with the wire transfer instructions in the applicable Tag-Along Response Notices, and any non-cash portion to be delivered in such manner as the Tag-Along Seller may reasonably determine after consultation with the Tagging Persons and (iii) promptly after the consummation of such Tag-Along Sale, furnish such other evidence of the completion and the date of completion of such transfer and the terms thereof as may be reasonably requested by the Tagging Persons. (f) If, at the termination of the Tag-Along Notice Period, any Tag-Along Offeree shall not have elected to participate in the Tag-Along Sale, such Tag-Along Offeree shall be deemed to have waived its rights under Section 4.01(a) with respect to the Transfer of its Company Securities pursuant to such Tag-Along Sale. (g) If (i) any Tag-Along Offeree declines to exercise its Tag-Along Rights or (ii) any Tagging Person elects to exercise its Tag-Along Rights with respect to less than such Tagging Person's Tag-Along Portion, the Tag-Along Seller shall be entitled to Transfer, pursuant to the Tag-Along Offer, up to a number of Company Securities held by it equal to the number of Company Securities constituting, as the case may be, the Tag-Along Portion of such Tag-Along Offeree or up to the portion of such Tagging Person's Tag-Along Portion with respect to which its Tag-Along Rights were not exercised. (h) Notwithstanding anything contained in this Section 4.01, there shall be no liability on the part of the Tag-Along Seller to any Tag-Along Offeree or Tagging Person (other than the obligation to return any certificates evidencing Company Securities and limited powers-of-attorney received by the Tag-Along Seller from any Tagging Person) if the Transfer of Company Securities pursuant to Section 4.01 is not consummated for any reason. The decision as to whether to effect a Transfer of Company Securities pursuant to this Section 4.01 by the Tag-Along Seller is in the sole and absolute discretion of the Tag-Along Seller. (i) The provisions of this Section 4.01 shall not apply to any proposed Transfer of any class of Company Securities by the Tag-Along Seller (i) in a Public Offering or (ii) under Rule 144 pursuant to Section 3.05. 21  Section 4.02. Additional Conditions to Tag-Along Sales. Notwithstanding anything contained in Section 4.01, the rights and obligations of the Shareholders to participate in a Tag-Along Sale under Section 4.01, are subject to the following conditions: (a) upon the consummation of such Tag-Along Sale, all of the Shareholders participating therein will receive the same form and amount of consideration per share, or, if any Shareholders are given an option as to the form and amount of consideration to be received, all Shareholders participating therein will be given the same option; (b) each Shareholder shall (i) make such representations, warranties and covenants and enter into such definitive agreements as are customary for transactions of the nature of the proposed Transfer (including agreements providing for indemnification of a purchaser, provided that such indemnification obligations are several, and not joint, and that such Shareholder shall not be liable pursuant to such obligations for more than it received as consideration for its Company Securities pursuant to such Tag-Along Sale), (ii) benefit from all of the same provisions of the definitive agreements as the Tag-Along Seller, and (iii) be required to bear their proportionate share of any escrows, holdbacks or adjustments in purchase price. ARTICLE 5 REGISTRATION RIGHTS Section 5.01. Demand Registration. (a) If the Company shall receive a notice from either UDCL or one or more Somerset Group Members whose collective Aggregate Ownership of Shares (direct and/or indirect) is not less than 15% of the total outstanding Shares of the Company, calculated on a Fully-Diluted basis (UDCL or such requesting Somerset Group Members (acting as a group), as the case may be, a "REQUESTING SHAREHOLDER"), requesting that the Company effect the registration under the Securities Act of all or any portion of such Requesting Shareholder's Registrable Securities and specifying the intended method of disposition thereof (each such request, a "DEMAND REGISTRATION," any Demand Registration by such requesting Somerset Group Members, a "SOMERSET DEMAND REGISTRATION" and any Demand Registration by UDCL, a "UDCL DEMAND REGISTRATION"), then the Company shall promptly give notice of such Demand Registration at least 15 Business Days prior to the anticipated filing date of the registration statement relating to such Demand Registration to the other Shareholders and thereafter shall use its reasonable best efforts to effect, as expeditiously as possible but in any event within 60 days after the Demand Registration date, the registration under the Securities Act of: 22  (i) all Registrable Securities for which the Requesting Shareholders have requested registration under this Section 5.01, and (ii) subject to the restrictions set forth in Sections 5.01(f) and 5.02, all other Registrable Securities of the same class as those requested to be registered by the Requesting Shareholders that any Shareholders with rights to request registration under Section 5.02 (all such Shareholders, together with the Requesting Shareholders, the "REGISTERING SHAREHOLDERS") have requested the Company to register by request received by the Company within 15 Business Days after such Shareholders receive the Company's notice of the Demand Registration, all to the extent necessary to permit the disposition of the Registrable Securities so to be registered; provided that, subject to Section 5.01(e), the Company shall not be obligated to effect any Demand Registration (on any form) during a Lock-Up Period or more than (i) one Demand Registration (on any form) in any 6-month period (other than Demand Registrations pursuant to a Shelf Registration, with respect to which the Company shall not be obligated to effect more than one Demand Registration (on any form) in any 3-month period), (ii) 2 UDCL Demand Registrations on Form S-1 or (iii) 2 Somerset Demand Registrations on Form S-1 (it being understood that clauses (ii) and (iii) shall not limit the ability of UDCL or the Somerset Group Members as Requesting Shareholders, to request an unlimited number of Demand Registrations on Form S-3 in accordance with the other provision of this Section 5.01(a)). Notwithstanding the foregoing, the Company shall not be required to effect any Demand Registrations unless the aggregate value of the Registrable Securities requested to be included in such Demand Registration meets the Minimum Value. (b) Subject to Section 5.01(a), if at any time after the Company is eligible to file a registration statement on Form S-3, any Requesting Shareholder makes a Demand Registration to effect a Shelf Registration, then the Company shall promptly give notice of such Demand Registration at least 15 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 best efforts to effect, as expeditiously as possible but in any event within 60 days after such Demand Registration date, the Shelf Registration of: (i) all Registrable Securities for which the Requesting Shareholders have requested registration under this Section 5.01(b), and (ii) all other Registrable Securities of the same class as those requested by the Requesting Stockholders that any other Registering Shareholders have requested the Company to register pursuant to Section 23  5.02 by request received by the Company within 15 Business Days after such other Registering Shareholders receive the Company's notice of the Demand Registration to effect such Shelf Registration, and to cause such Shelf Registration to become effective and to keep such Shelf Registration in effect for at least one year (or such shorter period in which all Registrable Securities of the Registering Shareholders included in such registration have actually been sold thereunder); provided that the Company shall not be obligated to file such Shelf Registration, unless such Shelf Registration meets the Minimum Shelf Value; and provided further that the Company shall not be obligated to effect more than three Shelf Registrations in any two-year period. Any offer or sale of Registrable Securities pursuant to a Shelf Registration in any underwritten Public Offering shall be deemed to be a Demand Registration subject to the provisions of Section 5.01(a). A Shelf 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 one year (or such shorter period in which all Registrable Securities of the Registering Shareholders included in such registration have actually been sold thereunder). The Company shall be liable for and pay all Registration Expenses in connection with effecting a Shelf Registration, except if such Shelf Registration is revoked at the request of the Requesting Shareholder initiating the request for such Shelf Registration, in which case such Requesting Shareholder shall pay all such Registration Expenses. (c) Promptly after the expiration of the 15-Business-Day-period referred to in Section 5.01(a)(ii), the Company will notify all Registering Shareholders of the 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 Shareholders 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 (i) such revocation arose out of the fault of the Company (in which case the Company shall be obligated to pay all Registration Expenses in connection with such revoked request), or (ii) the Requesting Shareholders reimburse the Company for all Registration Expenses of such revoked request. (d) The Company shall be liable for and pay all Registration Expenses in connection with any Demand Registration, regardless of whether such Registration is effected, except as set forth in Section 5.01(c). (e) A Demand Registration shall not be deemed to have occurred: 24  (i) unless the registration statement relating thereto (A) has become effective under the Securities Act and (B) has remained effective for a period of at least 180 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; or (ii) if the Maximum Offering Size is reduced in accordance with Section 5.01(f) such that less than 66 2/3% of the Registrable Securities of the Requesting Shareholders sought to be included in such registration are included. (f) If a Demand Registration involves an underwritten Public Offering and the managing underwriter advises the Company and the Requesting Shareholders 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 by the Registering Shareholders, allocated, if necessary for the offering not to exceed the Maximum Offering Size, by registering on behalf of each Registering Shareholder such number of Registrable Securities which is the lesser of: (x) the number of Registrable Securities that such Registering Shareholder requested to be included in such Public Offering, and (y) the product of such Registering Shareholder's Pro Rata Share of Registrable Securities and the Maximum Offering Size; and (ii) second, any securities proposed to be registered for the account of any other Persons (including the Company), with such priorities among them as the Company shall determine. (g) Upon notice to each Requesting Shareholder, the Company may on one occasion during any period of six consecutive months postpone effecting a registration pursuant to this Section 5.01 for a reasonable time specified in the 25  notice but not exceeding 90 days (which period may not be extended or renewed), if (i) an investment banking firm of recognized national standing shall advise the Company and the Requesting Shareholders in writing 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 5.02. Piggyback Registration. If the Company proposes to register any Company Securities under the Securities Act (other than a registration on Form S-8 or S-4, or any successor forms, relating to Common Shares or any other class of Company Securities 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 30 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 5.02 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 5.02(b). Upon the request of any such Shareholder made within 15 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 all 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 5.04(f) on the same terms and conditions as apply to the Company or the Requesting Shareholders, as applicable, and (ii) if, at any time after giving notice of its intention to register any Company Securities pursuant to this Section 5.02(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 5.02 shall relieve the Company of its obligations to effect a Demand Registration 26  to the extent required by Section 5.01. 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 5.01(f) 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 Company Securities proposed to be registered for the account of the Company 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 5.02, allocated, if necessary for the offering not to exceed the Maximum Offering Size, by registering on behalf of each such Shareholder such number of Registrable Securities which is the lesser of: (x) the number of Registrable Securities that such Shareholder requested to be included in the Public Offering pursuant to Section 5.02, and (y) the product of such Shareholder's Pro Rata Share of Registrable Securities and the Maximum Offering Size; 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 5.03. Lock-Up Agreements. If any registration of Registrable Securities shall be effected in connection with a Public Offering, neither the Company nor any Shareholder shall effect any public sale or distribution, including any sale pursuant to Rule 144, of any Company Securities (except as part of such Public Offering) during the period beginning 14 days prior to the effective date of the applicable registration statement until such time as the Company and the lead managing underwriter shall agree (such period, the "LOCK-UP PERIOD" for the applicable registration statement). Section 5.04. Registration Procedures. Whenever Shareholders request that any Registrable Securities be registered pursuant to Section 5.01 or 5.02, subject to the provisions of such Sections, the Company shall use all reasonable efforts to effect the registration and the sale of such Registrable Securities in 27  accordance with the intended method of disposition thereof as quickly as practicable, and, in connection with any such request: (a) The Company shall as expeditiously as possible 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 all reasonable efforts to cause such filed registration statement to become and remain effective for a period of not less than 180 days, or in the case of registration statement for a Shelf Registration, one year (or such shorter period in which all of the Registrable Securities of the Registering Shareholders included in such registration statement shall have actually been sold thereunder). (b) Prior to filing a registration statement or prospectus or any amendment or supplement thereto, 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 or Rule 430A 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 Registrable 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 all reasonable efforts to (i) register or qualify the Registrable Securities covered by such registration statement under 28  such other securities or "blue sky" laws of such jurisdictions in the United States as any 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 5.04(d), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction. (e) The Company shall immediately notify each Shareholder holding such Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and promptly prepare and make available to each such Shareholder and file with the SEC any such supplement or amendment. (f) UDCL shall have the right to select any underwriters in connection with a registration resulting from the exercise of a UDCL Demand Registration, which underwriters may include any Affiliate of the MSCP Funds and shall be reasonably satisfactory to the Somerset Group Members, (ii) the Somerset Group Members shall have the right to select the underwriters in connection with any Somerset Demand Registrations, which underwriters shall be reasonably satisfactory to UDCL and (iii) the Company shall have the right to select each underwriter in connection with any other Public Offering, as determined by the Board. 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, including the engagement of a "qualified independent underwriter" in connection with the qualification of the underwriting arrangements with the NASD. (g) Upon execution of confidentiality agreements in form and substance reasonably satisfactory to the Company, the Company shall make available for 29  inspection by any Registering Shareholder and any underwriter participating in any disposition pursuant to a registration statement being filed by the Company pursuant to this Section 5.04 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. Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such registration statement or (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each Registering 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 Company Securities unless and until such information is made generally available to the public. Each Registering 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. (h) The Company shall furnish to each Registering Shareholder of Registrable Securities covered by a registration statement and to each such underwriter, if any, a signed counterpart, addressed to such Shareholder or underwriter, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company's independent public accountants, each in customary form and covering such matters of the kind customarily covered by opinions or comfort letters, as the case may be, as a majority of such Shareholders or the managing underwriter therefor reasonably requests. (i) The Company shall otherwise use all reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement or such other document covering a period of 12 months, beginning within three months after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder. 30  (j) The Company may require each such Registering 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 request and such other information as may be legally required in connection with such registration, including information regarding the beneficial ownership of Company Securities requested for registration on behalf of any particular member of UDCL (rather than for the benefit of all members of UDCL). (k) Each such Registering Shareholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5.04(e), 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 5.04(e), 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, the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 5.04(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 5.04(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 5.04(e). (l) The Company shall use all reasonable efforts to list all Registrable Securities covered by such registration statement on any securities exchange or quotation system on which any of the Registrable Securities are then listed or traded. (m) The Company shall have appropriate officers of the Company (i) prepare and make presentations at any "road shows" and before analysts and rating agencies, as the case may be, (ii) take other actions to obtain ratings for any Registrable Securities and (iii) otherwise use their reasonable best efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of the Registrable Securities. Section 5.05. Indemnification by the Company. The Company agrees to indemnify and hold harmless each Registering Shareholder holding Registrable Securities covered by a registration statement, its officers, directors, employees, partners and agents, and each Person, if any, who controls such Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and 31  expenses (including reasonable expenses of investigation and reasonable attorneys' fees and expenses) ("DAMAGES") caused by or relating to any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities of such Shareholder (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such Damages are caused by or directly related to any such untrue statement or omission or alleged untrue statement or omission so made based upon information furnished in writing to the Company by such Shareholder or on such Shareholder's behalf expressly for use therein; provided that, with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus, or in any prospectus, as the case may be, the indemnity agreement contained in this paragraph shall not apply to the extent that any Damages result from the fact that a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) was not sent or given to the Person asserting any such Damages at or prior to the written confirmation of the sale of the Registrable Securities concerned to such Person if it is determined that the Company has provided such prospectus to such Shareholder and it was the responsibility of such Shareholder to provide such Person with a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) would have cured the defect giving rise to such Damages. The Company also agrees to indemnify any underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of 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 Shareholders provided in this Section 5.05. Section 5.06. Indemnification by Participating Shareholders. Each Registering 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 indemnity from the Company to such Shareholder described in Section 5.05, but only (i) 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 (ii) to the extent that any Damages result from the fact that a current copy of the prospectus (or such amended or 32  supplemented prospectus, as the case may be) was not sent or given to the Person asserting any such Damages at or prior to the written confirmation of the sale of the Registrable Securities to such Person if it is determined that it was the responsibility of such Shareholder to provide such Person with a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) would have cured the defect giving rise to such loss, claim, damage, liability or expense. 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 5.06. As a condition to including Registrable Securities in any registration statement filed in accordance with Article 5, 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 Registering Shareholder shall be liable under this Section 5.06 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 5.07. 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 5, 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 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 33  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 5.08. Contribution. (a) If the indemnification provided for in this Article 5 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 Registering 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, whether the untrue or alleged 34  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. (b) The Company and the Registering Shareholders agree that it would not be just and equitable if contribution pursuant to this Section 5.08 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 5.08, 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 Registering 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 Registering Shareholder's obligation to contribute pursuant to this Section 5.08 is several in the proportion that the proceeds of the offering received by such Registering Shareholder bears to the total proceeds of the offering received by all such Registering Shareholders and not joint. Section 5.09. Participation in Public Offering. No Person may participate in any Public Offering hereunder unless such Person (a) agrees to sell such Person's securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) 35  completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and the provisions of this Agreement in respect of registration rights. Section 5.10. Other Indemnification. Indemnification similar to that specified herein (with appropriate modifications) shall be given by the Company and each Registering Shareholder participating therein with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act. Section 5.11. Cooperation by the Company. Subject to Section 3.05, 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 as such Shareholder shall reasonably request. ARTICLE 6 CERTAIN COVENANTS Section 6.01. Confidentiality. Each Shareholder will, and will use its reasonable efforts to cause its respective Affiliates and its and their respective officers, directors, employees, accountants, counsel, consultants, advisors' agents and financing parties (collectively, the "AGENTS") to hold in confidence, unless compelled to disclose by judicial or administrative process or by other requirements of law, all documents and information concerning the Company or its Affiliates (the "CONFIDENTIAL INFORMATION") that is furnished to such Shareholder or its Agents in connection with the Company, the Company's business or the transactions contemplated hereby and will use such information solely in connection with its ownership of Company Securities; provided that "CONFIDENTIAL INFORMATION" shall not include, and no Shareholder shall have any obligation with respect to, information (i) that has become public from a source other than such Shareholder or its Agents, (ii) that has become available to such Shareholder on a non-confidential basis from a source that is not, to such Shareholder's knowledge, under an obligation of confidentiality or (iii) that has been developed by or on behalf of such Shareholder or its Agents independently of any disclosure from the Company or its Subsidiaries or any other Shareholder or its Agents. A Shareholder may disclose Confidential Information to its Agents so long as such Agents are informed by such Shareholder of the confidential nature of such information and provided that in any event such Shareholder will be responsible for any breach of this Section by its Agents. The parties agree to keep this Agreement and its contents confidential and, except as may be required 36  by applicable law or any listing agreement with or rule of any national securities exchange or quotation system, will not issue any press release or public statement with respect to this Agreement or the transactions contemplated hereby without the consent of the other parties hereto. Section 6.02. Information Rights. The Company agrees to furnish (i) to the MSCP Funds, for so long as the Aggregate Ownership of Shares by UDCL is at least 5% of the total outstanding Shares of the Company, calculated on a Fully-Diluted basis and (ii) to each of the Original Somerset Group Members for so long as the collective Aggregate Ownership of Shares (direct and/or indirect) by the Somerset Group Members is at least 5% of the total outstanding Shares of the Company, calculated on a Fully-Diluted basis: (a) as soon as practicable and, in any event within 30 days after the end of each month, the unaudited consolidated balance sheet of the Company and its Subsidiaries as at the end of such month and the related unaudited statements of income and cash flow for such month, and for the portion of the fiscal year then ended, in each case prepared in accordance with GAAP, setting forth in comparative form the figures for the corresponding month and portion of the previous fiscal year, and the figures for the corresponding month and portion of the then current fiscal year as in the Company's annual operating budget; (b) as soon as practicable and, in any event, within 45 days after the end of each of the first three fiscal quarters, the unaudited consolidated balance sheet of the Company and its Subsidiaries as at the end of such quarter and the related unaudited statements of income and cash flow for such quarter and for the portion of the fiscal year then ended, in each case prepared in accordance with GAAP; (c) as soon as practicable and, in any event, within 90 days after the end of each fiscal year, (i) the audited consolidated balance sheet of the Company and its Subsidiaries as at the end of such fiscal year and the related audited statements of income and cash flow for such fiscal year, and for the portion of the fiscal year then ended, in each case prepared in accordance with GAAP and certified by Ernst & Young LLP or another firm of independent public accountants of nationally recognized standing, together with a comparison of the figures in such financial statements with the figures for the previous fiscal year and the figures in the Company's annual operating budget, (ii) any management letters or other correspondence from such accountants and (iii) the Company's annual operating budget for the coming fiscal year; (d) promptly following the preparation thereof, a copy of any revisions to the annual operating budget delivered pursuant to clause (c) above; 37  (e) promptly upon their becoming available, copies of (i) all financial statements, reports, notices and proxy statements sent or made generally available by the Company to any of its security holders, (ii) all regular and periodic reports and all registration statements and prospectuses filed by the Company with any securities exchange or with the SEC and (iii) all press releases and other statements made generally available by the Company to the public; (f) as soon as practicable and, in any event, within five Business Days after any officer of the Company obtains knowledge thereof, notice (with a description in reasonable detail, and stating the action that the Company is taking or proposes to take with respect thereto) of (i) the commencement of any material litigation, investigation or other proceeding to which the Company or any of its Subsidiaries is a party before any court or arbitrator or any governmental body, agency or official or (ii) the existence of any material default or breach under this Agreement or any other material contract or agreement to which the Company or any of its Subsidiaries is a party; and (g) as promptly as reasonably practicable, such other information with respect to the Company or any of its Subsidiaries as may reasonably be requested by such Shareholder. ARTICLE 7 MISCELLANEOUS Section 7.01. Binding Effect; Assignability; Benefit. (a) This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, successors, legal representatives and permitted assigns. Any Shareholder that ceases to own beneficially at least 10% of the Company Securities he or it beneficially owns as of the date hereof or as of its date of joinder hereunder shall cease to be bound by the terms hereof (other than (i) the provisions of Sections 5.05, 5.06, 5.07, 5.08 and 5.10 applicable to such Shareholder with respect to any offering of Registrable Securities completed before the date such Shareholder ceased to own any Company Securities and (ii) Sections 6.01, 7.02, 7.04, 7.05, 7.06, 7.07 and 7.08). (b) Other than any Permitted Transferee of the Somerset Group Members or any UDCL Permitted Transferee acquiring Company Securities in compliance with the provisions of this Agreement, neither this Agreement nor any right, remedy, obligation or liability arising hereunder or by reason hereof shall be assignable by any party hereto pursuant to any Transfer of Company Securities or otherwise, except that (i) any Person acquiring Company Securities from any Shareholder (other than a Permitted Transferee of such Shareholder or any UDCL 38  Permitted Transferee) in a Private Sale in compliance with Article 3 (but excluding Transfers made pursuant to any employment agreement or stock purchase, option, stock option or other compensation plan of the Company or any Subsidiary to become a party hereto) shall (unless already bound hereby) execute and deliver to the Company an agreement to be bound by this Agreement in the form of Exhibit B hereto and (ii) any Person acquiring Company Securities from UDCL in a Private Sale in compliance with Article 3 (but excluding Transfers made pursuant to any employment agreement or stock purchase, option, stock option or other compensation plan of the Company or any Subsidiary to become a party hereto) shall (unless already bound hereby) execute and deliver to the Company an agreement to be bound by this Agreement in the form of Exhibit A hereto and, in each case, shall thenceforth be an "OTHER SHAREHOLDER". Nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties hereto, and their respective heirs, successors, legal representatives and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.
