**Item 4. Purpose of Transaction**

Merger

Item 3 above includes a description of the Merger and is incorporated by reference to this Item 4.

Registration Rights Agreement

In connection with the Merger, American entered into a Registration Rights Agreement (the "Registration Rights Agreement") with the Issuer and the other parties named therein, which become effective on the Closing Date. The Registration Rights Agreement provides for customary "demand" registrations and "piggyback" registration rights. The Issuer will also pay certain expenses relating to such registrations and indemnify the registration rights holders against (or make contributions in respect of) certain liabilities which may arise under the Securities Act.

The Registration Rights Agreement also contains a lock up provision whereby American agrees, subject to certain customary exceptions, not to dispose of any shares of Common Stock during the period beginning on the Closing Date and continuing to and including the date that is 180 days after the Closing Date.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is attached as an exhibit to this Schedule 13D and incorporated herein by reference.

General

The Reporting Persons acquired the securities described in this Schedule 13D in connection with the closing of the Merger and intend to review their investment in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons' review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer's business, financial condition, operations and prospects; price levels of the Issuer's securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

Subject to the Registration Rights Agreement, the Reporting Persons may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons may engage in discussions with management, the board of directors, other securityholders of the Issuer and other relevant parties, or encourage, cause or seek to cause the Issuer or such persons to consider or explore extraordinary corporate transactions, such as: a merger, reorganization or other transaction that could result in the de-listing or de-registration of the Common Stock; security offerings and/or stock repurchases by the Issuer; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer's business or corporate structure, including changes in management or the composition of the board of directors.

To facilitate their consideration of such matters, the Reporting Persons may retain consultants and advisors and may enter into discussions with potential sources of capital and other third parties. The Reporting Persons may exchange information with any such persons pursuant to appropriate confidentiality or similar agreements. The Reporting Persons will likely take some or all of the foregoing steps at preliminary stages in their consideration of various possible courses of action before forming any intention to pursue any particular plan or direction.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.
