Item 3.         Source and Amount of Funds or Other Consideration

On February 22, 2007, the Company acquired (the “Acquisition”) all of the outstanding shares of Avantair, Inc., a Nevada corporation, from the Reporting Persons and certain other selling stockholders in exchange for an aggregate of 6,684,822 shares of Company common stock (collectively, the “Sellers”) pursuant to a Stock Purchase Agreement, dated October 2, 2006, as amended by that certain Amendment to the Stock Purchase Agreement, dated December 15, 2006 (collectively, the “Stock Purchase Agreement”), the forms of which are listed as Exhibit 1 and Exhibit 2 hereto. The Acquisition consideration received by the Sellers consisted of 6,684,822 shares of Common Stock, of which 756,426 shares were issued to the Reporting Persons.

Item 4.         Purpose of Transaction

The Reporting Persons acquired the shares of Common Stock for investment purposes. The Reporting Persons may, from time to time, depending upon market conditions and other factors deemed relevant by the Reporting Persons, acquire additional shares of Common Stock or warrants to purchase shares of Common Stock. The Reporting Persons reserve the right to, and may in the future choose to, change their purpose with respect to their investment and take such actions as they deem appropriate in light of the circumstances including, without limitation, to dispose of, in the open market, in a private transaction or by gift, all or a portion of the shares of Common Stock which they now own or may hereafter acquire.

In addition, under the Stock Purchase Agreement, the Sellers, which include the Reporting Persons, have a contingent right to acquire additional shares of Common Stock (collectively, the “Contingent Shares”) as follows:

• At the end of the fiscal year ending June 30, 2007, the Company will calculate (based on its annual audited consolidated financial statements for such fiscal year) its net income or loss, plus (i) interest expense, (ii) total taxes paid or payable, and (iii) depreciation and amortization expense, all as determined on a consolidated basis in accordance with generally accepted accounting principles (except, for the purposes of this calculation, any revenues generated by the Company with respect to sales of aircraft (or interests therein) and the associated costs shall be treated as recognized in the fiscal year of sale and not amortized over a period of several years). If this calculated amount, which is sometimes referred to as Cash EBITDA, is greater than $6,000,000 for the fiscal year ending June 30, 2007, the Company will issue an aggregate of 954,975 shares of Common Stock to the Sellers.

• At the end of the fiscal year ending June 30, 2008, the Company will calculate (based on its annual audited consolidated financial statements for such fiscal year) Cash EBITDA. If Cash EBITDA is greater than $20,000,000 for the fiscal year ending June 30, 2008, the Company will issue an aggregate of 4,774,873 shares of Common Stock to the Sellers.

Page 5

• If at any time after the closing of the acquisition but prior to February 23, 2009, the closing trading price on the Over-the-Counter Bulletin Board (or on a national securities market on which the Company’s shares of Common Stock are then quoted for trading) of the shares of Common Stock for 20 trading days within any 30 trading day period equals or exceeds $8.50 per share, then the Company will issue an additional aggregate of 4,774,873 shares of Common Stock to the Sellers.

In the event that, at any time following the closing and prior to February 23, 2009, the Company consummates a merger or similar transaction with a third party which results in a change of control of the Company, or consummates a sale of all or substantially all of the Company’s assets, in each case for aggregate consideration equal to at least the product of (x) $8.50 and (y) the aggregate number of shares of Common Stock issued and outstanding after giving effect to the issuance to the Sellers of all shares of Common Stock under the Stock Purchase Agreement (including all deferred payments) and full exercise or conversion of all of warrants, options and other convertible securities exercisable for or convertible into Common Stock then outstanding, then the Company shall issue to the Sellers a number of shares of Common Stock equal to the maximum amount of the deferred payments which could be issued to the Sellers under the Stock Purchase Agreement with respect to each fiscal year ending June 30, 2007 and 2008 which has not yet been completed, and assuming the trading price of the Common Stock had satisfied the criteria for the issuance of deferred payments.

The Reporting Persons have the right to acquire approximately 11.32% of any Contingent Shares described above which are issued to the Sellers.

Other than as set forth herein, none of the Reporting Persons have any plans or proposals that relate to or would result in any of the following:

(a) The acquisition of additional securities of the Company, or the disposition of securities of the Company;

(b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company;

(c) A sale or transfer of a material amount of assets of the Company;

(d) Any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board;

(e) Any material change in the present capitalization or dividend policy of the Company;

(f) Any other material change in the Company’s business or corporate structure;

Page 6

(g) Any other material changes in the Company’s charter, by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person;

(h) Causing a class of securities of the Company to be delisted from a national securities exchange or ceasing to be authorized to be quoted on an inter-dealer quotation system of a registered national securities association;

(i) A class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or

(j) Any action similar to those enumerated above.

Item 5.         Interest in Securities of the Issuer

(a) The Reporting Persons together are the beneficial owners of 756,426 shares of Common Stock. This constitutes approximately 5.00% of the shares of Common Stock outstanding.

The percentage ownership of the Reporting Persons in the Company’s capital stock is based on 15,084,822 issued and outstanding shares of Common Stock according to information provided by the Company to the Reporting Persons.

(b) The responses of the Reporting Persons to Items (7) through (11) of pages 2 and 3 hereto are incorporated herein by reference.

(c) The Reporting Persons have not effected any transactions in shares of Common Stock during the past sixty days other than as described in Item 3 of this Schedule 13D.

(d) Except as described herein, no person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities covered by this Schedule 13D.

(e) Not applicable.

Item 6.         Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

On February 22, 2007, the Reporting Persons, along with certain other stockholders of the Company, entered into a Stockholders Agreement with the Company (the “Stockholders Agreement”) which is listed as Exhibit 3 hereto, in which the Reporting Persons agreed not to transfer, sell, assign, pledge or otherwise dispose of 756,426 of the shares of Common Stock they received at the closing of the Acquisition, other than certain permitted transfers to relatives,

Page 7

affiliates, family trusts and the like. Subject to securities laws, these restrictions lapse with respect to one-third of the shares of Common Stock held by the Reporting Persons for every six months following the closing of the Acquisition.

Under the Stockholders Agreement, the Reporting Persons have also agreed to designate certain individuals for election to the Company’s board of directors and to vote for such individuals. The Company’s initial stockholders shall have the right to designate three directors, who shall initially be Barry J. Gordon (who shall also be elected non-executive Chairman of the Company’s Board of Directors), Arthur H. Goldberg and Stephanie A. Cuskley. Two of the Company’s initial stockholders’ designees must qualify as “independent” directors under applicable securities laws and applicable market exchange rules. The Sellers shall have the right to designate four directors, who shall initially be Steven Santo, John Waters, A. Clinton Allen and Robert J. Lepofsky. Two of the designees of the Sellers’ stockholders (including the designee who is subject to Company’s consent) must also qualify as an independent directors. Except as set forth above, the respective rights of the initial stockholders of the Company and the Sellers will terminate on the later of 60 days following the date on which the Company files its Form 10-K with respect to the fiscal year ending June 30, 2008, and the date on which each group beneficially owns (on a collective basis) less than 50% of the percentage of the Company’s common stock that they beneficially own (on a collective basis) immediately following the closing of the Acquisition.
