WITNESSETH

WHEREAS, the Company has agreed to offer the Noteholders an option to exchange their Notes for ordinary shares, par value $0.002, of the Company (the “Shares”) upon the terms and subject to the conditions set forth in this Agreement.

NOW THEREFORE, in consideration of the mutual terms, conditions, representations, warranties and agreements herein set forth, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

Section 1. Definitions.

A. Capitalized terms used but not defined herein, shall have the meanings provided in the Note Purchase Agreement (defined below).

B. Unless the context otherwise requires, the terms defined in this Section 1, whenever used in this Agreement shall have the respective meanings hereinafter specified and words in the singular or in the plural shall each include the singular and the plural and the use of any gender shall include all genders.

“Amendment to Note Purchase Agreement” means the Amendment to the Note Purchase Agreement to be entered into between the Company and Noteholders holding at least 80% of the then outstanding principal amount of all Notes (other than Notes owned by the Company or any other obligor of the Notes) consenting to (i) an amendment to (a) allow the Company to issue Options entitling Noteholders to exchange their Notes for Shares and acquire Notes in exchange for Shares upon the exercise of such Options, in each case, on the terms and conditions set forth in this Agreement and (b) eliminate the prohibition on Note repurchases by the Company subject to certain conditions; (ii) a clarifying amendment to make clear that repurchases of Subordinated Debt permitted under the Senior Credit Agreement are not prohibited under the terms of the Notes; and (iii) amendments to the notice provision to (y) update AEI Services LLC’s mailing address and (z) provide for the delivery of notices via e-mail.

“Consents” means (i) the Amendment to Note Purchase Agreement and (ii) the Shareholders Consent.

“Note Purchase Agreement” means the Note Purchase Agreement, dated as of May 24, 2007, among the Company and the purchasers identified therein, as amended by the Amendment to Note Purchase Agreement and as may be hereafter further amended, supplemented or modified from time to time.

“Option Commencement Date” shall mean the date on which the Company delivers notice to the Noteholders that all requisite Consents have been obtained.

“Option Expiration Date” shall mean the date that is 12 months after the Option Commencement Date.

“Shareholders Agreement” means the Second Amended and Restated Shareholders Agreement, dated as of May 9, 2008, among the Company and the shareholders identified therein (as the same may be amended, modified or supplemented from time to time).

“Shareholders Consent” means the consent of the Company’s shareholders party to the Shareholders Agreement waiving the preemptive rights, related party and certain other provisions of the Shareholders Agreement necessary to permit the exchange of Notes for Shares contemplated by this Agreement.

Section 2. Issuance of Options; Transfers.

A. On the terms and subject to the conditions hereof, effective upon receipt of the requisite Consents, the Company hereby issues and grants to each Noteholder an irrevocable right and option (the “Option”) to exchange any or all of the Notes held by such Noteholder for Shares of the Company. The Options granted hereby will be evidenced by the Note Certificates representing the Notes and no separate certificates in respect of the Options will be issued.

B. The Options will be transferable only in connection with the transfer of the underlying Notes and will be subject to same transfer restrictions as the Notes. The surrender for transfer of any Note Certificate will also constitute the transfer of the Options associated with the Notes evidenced by such certificates.

C. No separate listing for the Options will be obtained.

Section 3. Exercise Date; Exercise of Options.

A. Option Period; Exchange Ratio. The Options will be exercisable on and after the Option Commencement Date and prior to 5:00 p.m., New York City time, on the Option Expiration Date (the “Option Period”). A Noteholder that exercises its Option, in whole or in part, on the Option Commencement Date will receive sixty-three (63) Shares (the Shares issuable upon exercise of the Options being collectively referred to herein as the “Option Shares”) for each $1,000 principal amount of Notes exchanged. Thereafter, the exchange ratio shall be reduced in accordance with the schedule attached hereto as Schedule A (which may be modified to reflect a different Option Commencement Date in the event that the deadline for the Consent solicitation by AEI is extended or shortened by AEI at its option). Any accrued but unpaid interest on Notes surrendered for exchange shall likewise be exchanged for Shares at the same exchange rate as that applicable with respect to the principal amount of such Notes. No Option shall be exercisable prior to the Option Commencement Date or after 5:00 p.m., New York City time, on the Option Expiration Date and Options shall only be exercisable to the extent and in the manner herein provided.

B. Exercise. Subject to the terms and conditions set forth in this Section 3, Options may be exercised at any time or from time to time on and after the Option Commencement Date until 5:00 p.m., New York City time, on the Option Expiration Date.

A Noteholder may exercise the Option granted hereby with respect to any or all of the Notes registered in the name of such Noteholder on the books and records of the Company (or its transfer agent) by

delivering to the Company at its office referred to in Section 10 the following: (i) a written notice of exercise, completed and submitted in accordance with the terms of such notice, in the form attached hereto as Exhibit A (the “Notice of Exercise”), (ii) the Note Certificate representing the Notes with respect to which the Option is being exercised, accompanied by a duly executed transfer certificate, (iii) an executed copy of the Shareholder Joinder Agreement (as defined in Section 8), if applicable and (iv) an executed Internal Revenue Service Form W-8 or W-9, as applicable. In addition, as provided in Section 8, any Noteholder not party to the Registration Rights Agreement that desires to become a party to such agreement, will also need to deliver an executed copy of the Registration Rights Joinder Agreement. If a Noteholder chooses to exercise the Option with respect to less than all of the Notes registered in the name of such Noteholder (a “partial exercise”), such partial exercise must be in a minimum principal amount $1,000 or an integral multiple thereof. A partial exercise does not preclude a subsequent exercise provided all the terms and conditions to such exercise are met.

All rights of a Noteholder with respect to any Option that has not been exercised, prior to 5:00 p.m., New York City time, on the Option Expiration Date shall immediately cease and all such unexercised Options shall be automatically cancelled and void.

C. Payment of Taxes. The Company shall pay any and all Cayman Islands issue, documentary or stamp taxes that may be payable in respect of any issuance or delivery of Option Shares in exchange for the Notes. All other taxes that may be payable in respect of any issuance of Option Shares shall be the responsibility of the applicable Noteholder.

D. Delivery of Option Shares. Upon receipt of the items referred to in Section 3B, the Company shall, as promptly as practicable, and in any event within three (3) Business Days thereafter, issue to Noteholder or Noteholder’s designee the number of Option Shares to be issued on exercise of the Option(s) and enter the name of Noteholder or Noteholder’s designee in the register of members of the Company as the registered holder of such Option Shares. An Option shall be deemed to have been exercised and such Option Shares shall be deemed to have been issued, and such holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date that such Notice of Exercise, together with the other items required to be delivered pursuant to Section 3B, are received by the Company. Any Notes surrendered upon exercise of Options shall be immediately retired and cancelled by the Company and may not be re-issued.

E. Legend on Option Shares. If certificates representing Option Shares are issued, each certificate representing shares of Option Shares shall bear a legend substantially to the following effect:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR AVAILABILITY OF AN EXEMPTION FROM THE REGISTRATION PROVISIONS OF

THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS.

IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE SECOND AMENDED AND RESTATED SHAREHOLDERS AGREEMENT, DATED AS OF MAY 9, 2008, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, BY AND AMONG AEI AND THE PARTIES THERETO, A COPY OF WHICH IS ON FILE IN THE OFFICE OF THE COMPANY.”

The requirement that the above legend regarding the Securities Act be placed upon certificates evidencing any Option Shares shall cease and terminate upon the occurrence of certain events set forth in the Shareholders Agreement. Upon the occurrence of any such event requiring the removal of a legend hereunder, the Company, upon the surrender of certificates containing such legend, shall, at its own expense, deliver to the holder of any such Option Shares as to which the requirement for such legend shall have terminated, one or more new certificates evidencing such Option Shares not bearing such legend.

Section 4. Adjustment of Number of Option Shares Issuable Upon Exercise of an Option.

A. Adjustment for Stock Splits, Stock Dividends, Recapitalizations. The number of Option Shares issuable upon exercise of each Option shall be proportionately adjusted to reflect any stock dividend, stock split, reverse stock split, recapitalization or the like affecting the number of outstanding Shares that occurs after the date hereof.

B. Adjustments for Reorganization, Consolidation, Merger. If after the date hereof, the Company (or any other entity, the stock or other securities of which are at the time receivable on the exercise of the Options), consolidates with or merges into another entity or conveys all or substantially all of its assets to another entity, then, in each such case, the Noteholder, upon any permitted exercise of an Option, at any time after the consummation of such reorganization, consolidation, merger or conveyance, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise of the Option prior to such consummation, the stock or other securities or property to which such Noteholder would have been entitled upon the consummation of such reorganization, consolidation, merger or conveyance if such Noteholder had exercised the Option immediately prior thereto, all subject to further adjustment as provided in this Section 4. Prior to giving effect to any reorganization, consolidation, merger or conveyance, the successor or purchasing entity in any such reorganization, consolidation, merger or conveyance (if other than the Company) shall duly execute and deliver to the Noteholder a written acknowledgment of such entity’s obligations under the Options and this Agreement.

C. Notice of Certain Events. Upon the occurrence of any event resulting in an adjustment in the number of Option Shares (or other stock or securities or property) receivable upon the exercise of the Options, the Company shall promptly thereafter (i) compute such adjustment, (ii) prepare a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based, and (iii) mail copies of such certificate to each Noteholder.

Section 5. Reservation of Option Shares.

The Company shall at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Shares, the aggregate number of the Option Shares deliverable upon the exercise of all outstanding Options, for the purpose of enabling it to satisfy any obligation to issue the Option Shares upon the exercise of the Options as provided herein.

Section 6. No Impairment.

The Company shall not, by amendment of its memorandum and articles of association, or through reorganization, consolidation, merger, dissolution, issuance or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid, directly or indirectly, the observance or performance of any of the terms of the Options or this Agreement, and shall at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of the Noteholders under the Options and this Agreement against wrongful impairment. Without limiting the generality of the foregoing, the Company: (i) shall not set or increase the par value of any Option Shares above the amount payable therefor upon exercise, and (ii) shall take all actions that are necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Option Shares upon the exercise of the Options.

Section 7. Representations and Warranties by the Company.

The Company represents and warrants to the each Noteholder as follows:

(i) The Company has the corporate power and authority to execute, deliver and perform this Agreement, issue the Options and issue the Option Shares upon exercise of the Options. The execution, delivery and performance of this Agreement by the Company and the issuance by the Company of the Options and the Option Shares upon exercise of the Options have been duly and validly authorized by all necessary corporate action on the part of the Company. This Agreement has been duly executed and delivered by the Company and upon obtaining the Consents will constitute a legally valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar Laws relating to creditors’ rights generally and by general equitable principles.

(ii) Subject to obtaining the Consents, the execution, delivery and performance by the Company of this Agreement and the issuance of the Options and the Option Shares upon exercise of the Options do not and will not (i) conflict with, or constitute a breach or default under, its Organizational Documents, (ii) violate, or constitute a breach or default under, or result in the termination, acceleration or cancellation of, or the loss of benefit under, any Contract to which the Company is a party or by which its assets may be bound or affected (whether upon lapse of time and/or the occurrence of any act or event or otherwise) or (iii) assuming the representations and warranties of each of the Noteholder set forth in their

respective Notice of Exercise are accurate, violate any Law or Order applicable to the Company or by which its assets may be bound, other than, in the case of clauses (ii) and (iii) above as would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the ability of the Company to perform its obligations under this Agreement or any Options issued pursuant hereto.

(iii) Assuming the representations and warranties of each of the Noteholders set forth in their respective Notice of Exercise are accurate, no Approval is necessary to be obtained or made by the Company in connection with the execution, delivery and performance of this Agreement or the issuance of the Options or the Option Shares upon exercise of the Option.

(iv) The Option Shares have been duly authorized and upon issuance will be validly issued, fully paid and nonassessable and free of preemptive or other similar rights, other than the rights set forth in the Shareholders Agreement.

B. Survival. The representations and warranties of the Company shall survive the date hereof.

Section 8. Registration Rights Agreement; Shareholder Agreement.

A. As provided in Section 3B, upon the exercise of any Option, Noteholders that are not already existing shareholders of the Company are required to execute and deliver to the Company a joinder agreement evidencing such Noteholder’s accession to the Shareholders Agreement (the “Shareholder Joinder Agreement”). Upon becoming a party to the Shareholders Agreement, a Noteholder shall be entitled to all of the rights and benefits thereof and shall be subject to all of the obligations of a shareholder thereunder.

B. Upon the exercise of any Option, Noteholders will be entitled (but shall not be obligated) to become a party to the Amended and Restated Registration Rights Agreement, dated as of December 29, 2006, among the Company and the shareholders identified therein (as the same may be amended, modified or supplemented from time to time) (the “Registration Rights Agreement”). If a Noteholder is not already, but wishes to become, a party to the Registration Rights Agreement, such Noteholder will be required to execute and deliver to the Company a joinder agreement evidencing such Noteholder’s accession to the Registration Rights Agreement (the “Registration Rights Joinder Agreement”, and together with the Shareholder Joinder Agreement, the “Joinder Agreements”).

C. Upon the request of a Noteholder, the Company will provide to the Noteholder copies of the most recently executed versions of the Registration Rights Agreement and Shareholders Agreement, together with all amendments or other modifications thereto. Prior to becoming a party to the Registration Rights Agreement and the Shareholder Agreement, a Noteholder shall have no rights thereunder, including no rights to consent to any amendments that may be made after the date hereof but prior to the date of such Noteholder becoming a party thereto.

D. The Option Shares to be issued to an exercising Noteholder are being issued pursuant to an exemption from registration under the Securities Act and applicable state securities laws and may only be transferred, sold or otherwise disposed of if registered, or an exemption from registration is available under the Securities Act and applicable state securities laws. Pursuant to the Notice of Exercise, an exercising Noteholder will be required to make certain representations in relation to the exemption from registration being relied on by the Company in connection with the issuance of the

Option Shares. In addition, the Option Shares are subject to the restrictions on transfer set forth in the Shareholders Agreement.

Section 9. No Rights or Liabilities as Shareholder.

No holder, as such, of any Option shall be entitled to vote, receive dividends or be deemed the holder of any Option Shares which may at any time be issuable on the exercise of an Option for any purpose whatever, nor shall anything contained herein be construed to confer upon the holder of any Option, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise), or to receive notice of meetings or other actions affecting shareholders or to receive dividend or subscription rights, or otherwise, until such Option shall have been exercised in accordance with the provisions hereof. Without limiting or otherwise modifying Section 6 hereof, no provision hereof, in the absence of affirmative action by a Noteholder to exchange its Notes for Option Shares shall give rise to any liability of such holder as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.
