ARTICLE II

RIGHT OF B MEMBERS TO HOLDING COMPANY SHARES UPON ADMISSION

2.1 If Admission takes place at any time on or prior to the Admission Expiration Date, LTI agrees to procure that the B Members shall, immediately prior to such Admission, receive in exchange for their Class B Membership Interests a number of Holding Company Shares equal to, in the aggregate, of 3.4 percent (the “Company Percentage”) of the issued share capital of the Holding Company upon Admission (to be divided between the B Members pro rata in proportion to their respective percentage interests in the Company). The parties acknowledge and agree that the Company Percentage has been calculated assuming receipt by the Company of an aggregate amount of $5,000,000 (the “Subscription Amount”) from the B Members for the Membership Interests. In the event that less than the full Subscription Amount is received by the Company, the Company Percentage shall be reduced to reflect the revised percentage calculated based on the actual aggregate amount received by the Company from the B Members for the Membership Interests (the “Actual Subscription Amount”) and shall be further reduced by an

-2-

amount equal to 0.035 percent as a result of the B Members’ failure to satisfy the full Subscription Amount. For example, if the Actual Subscription Amount equals $4,700,000, the Company Percentage shall be reduced from (i) 3.4 percent to (ii) an amount equal to 3.19 percent minus 0.035 percent.

2.2 The B Members will receive the Holding Company Shares to which they are entitled pursuant to this clause 2 by such mechanism as LTI considers appropriate, taking into account, as far as reasonably practicable, the tax consequences for the parties and the B Members. Such mechanism may involve the surrender, contribution, exchange or otherwise of the Class B Membership Interests. However neither party shall have any liability to the Company or any B Member in respect of any tax liability incurred by a B Member in respect of its receipt of Holding Company Shares or otherwise.

2.3 It shall be a condition of each B Member’s entitlement to Holding Company Shares that each Member agrees that, if required by the Holding Company’s Nominated Adviser or underwriter, it will enter into an agreement with the Holding Company and its Nominated Adviser or underwriter, in a form acceptable to the Holding Company and its Nominated Adviser or underwriter, not to dispose of any shares in the Holding Company which it receives for a period of up to 1 year from the date of Admission.

2.4 LTI undertakes to procure that all Holding Company Shares issued pursuant to this clause 2 shall

2.4.1 be fully paid; and

2.4.2 rank pari passu in all respects with the fully paid shares of the same class in the Holding Company.

2.5 The determination by the board of directors of the Holding Company as to the number of shares to which any B Member shall be entitled shall be final save in the case of manifest error.

ARTICLE III

GRANT OF RIGHTS FOLLOWING THE ADMISSION EXPIRATION DATE

3.1 If Admission has not occurred by the Admission Expiration Date, then as promptly as practicable following such date LTI shall elect one of the following options:

(i) If the LTI “A” Interests and the GMA Interests are owned, directly or indirectly, by one common holding company (the “Private Entity”), then LTI shall procure that the B Members shall receive, in exchange for their Class B Membership Interests, that number of shares or other equity interests in the Private Entity that would equal, in the aggregate, 3.51 percent (the “Private Entity Percentage”) of the issued share capital of such Private Entity as of the date of exchange and issuance (the “Private Entity Shares”); or

(ii) If the LTI “A” Interests and the GMA Interests are owned, directly or indirectly, by two separate holding companies (the “LTI/GMA Entities”), then LTI shall procure that the B Members shall receive, in exchange for their Class B Membership Interests, such

-3-

number of shares and/or other equity interests in each such LTI/GMA Entity that would give the B Members an aggregate indirect ownership interest in the LTI “A” interests and the GMA Interests equal to the Private Entity Percentage. If LTI elects the option set forth in this clause 3.1(ii), then references elsewhere in this Agreement to the “Private Entity” and “Private Entity Shares” shall be construed, where the context permits, to apply to such LTI/GMA Entities and the shares and/or other equity interests to be issued to the B Members thereunder.

3.2 The parties acknowledge and agree that the Private Entity Percentage has been calculated assuming receipt by the Company of the full Subscription Amount from the B Members. In the event that less than the full Subscription Amount is received by the Company, the Private Entity Percentage shall be reduced to reflect the revised percentage calculated based on the Actual Subscription Amount and shall be further reduced by an amount equal to 0.035 percent as a result of the B Members’ failure to satisfy the full Subscription Amount. For example, if the Actual Subscription Amount equals $4,700,000, the Private Entity Percentage shall be reduced from (i) 3.51 percent to (ii) an amount equal to 3.29 percent minus 0.035 percent.

3.3 The Private Entity Shares to be issued pursuant to clause 3.1 above shall be divided between the B Members pro rata in proportion to their respective percentage interests in the Company. The parties acknowledge and agree that no B Member will receive, as a result of this clause 3, any rights to any appointment to any office or committee of LTI or GMA.

3.4 The Company acknowledges and, in exchanging any Class B Membership Interests for, or otherwise acquiring, any interest in the Holding Company or the Private Entity a B Member will be deemed to acknowledge, as follows: LTI is a UK limited liability partnership carrying on the business of proprietary dealing in investments on behalf of its members. It is currently unregulated by the UK Financial Services Authority (“FSA”). The management of LTI has procured and received legal advice that the firm by reason of applicable exemptions with respect to the activities of dealing as principal and establishing or operating a collective investment scheme is not undertaking any activity which constitutes a regulated activity under the UK Financial Services and Markets Act 2000 (“FSMA”). LTI cannot, however, guarantee or warrant that the FSA or the courts will not adopt an interpretation of FSMA (or of any relevant Treasury order made under FSMA) that the exemptions relied upon do not apply. In the event it is determined by the FSA or the courts that any activity of LTI is a regulated activity then the firm (a) will be obliged to obtain authorisation from the FSA to undertake such activities; and (b) may be liable to financial penalties with respect to carrying on regulated activities without FSA authorisation and to suspend or cease activities which may constitute regulated activities unless or until authorisation is obtained. In advance of the proposed IPO LTI with its legal advisers shall be undertaking a due diligence review of whether there might be any reasonable basis for a determination that the regulated activity exemptions relied upon may not apply to the activities of the firm and whether there is any basis for, or merit in, seeking FSA authorisation for carrying on its existing or intended business.

3.5 The B Members will receive the Private Entity Shares to which they are entitled pursuant to this clause 3 by such mechanism as LTI considers appropriate, taking into account, as far as reasonably practicable, the tax consequences for the parties and the B Members. Such mechanism may involve the surrender, contribution, exchange or otherwise of the Class B

-4-

Membership Interests. However neither party shall have any liability to the Company or any B Member in respect of any tax liability incurred by a B Member in respect of its receipt of interests in the Private Entity or otherwise.

3.6 It shall be a condition of the B Members’ rights under this Agreement that they shall execute such other documents as may be reasonably required by LTI in connection with the transactions contemplated by this Agreement and by exercising such rights and accepting any Holding Company Shares or Private Entity Shares the B Members will be deemed to acknowledge that such shares may be subject to legending requirements in accordance with applicable U.S. Securities laws and regulations.

4.1 Except as expressly provided in this agreement, a person who is not a party to this agreement shall not have any rights under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of this agreement.
