Item 3. Source and Amount of Funds or Other Consideration.

On August 23, 2006, Issuer entered into an Agreement and Plan of Merger, as amended by that First Amendment to the Agreement and Plan of Merger dated October 4, 2006, the Second Amendment to the Agreement and Plan of Merger dated December 1, 2006 and the Third Amendment to the Agreement and Plan of Merger dated December 21, 2006 (the “Merger Agreement”) with Solar Power, Inc., a California corporation (“SPI”) and the Issuer’s wholly-owned subsidiary, Welund Acquisition Corp., a Nevada corporation (“Merger Sub”). Effective as of December 29, 2006, pursuant to the Merger Agreement, the Merger Sub was merged with and into SPI, with SPI surviving as the Issuer’s wholly owned subsidiary (the “Merger”). The Merger was consummated on December 29, 2006, pursuant to which SPI became Issuer’s wholly owned subsidiary. In connection with the Merger the Issuer issued an aggregate of 14,500,000 shares of restricted common stock to the existing shareholders of SPI. Each share of common stock of SPI was cancelled and exchanged for one share of the Issuer’s common stock. As a result, Mr. Kircher, our Chief Executive Officer and Director who was also the Director and Chief Executive Officer of SPI, became the beneficial owner of 8,125,000 shares of Issuer’s common stock, including 2,000,000 shares issued to trusts held for benefit of his sons and 25,000 shares issuable upon the exercise of vested options. In addition, 2,000,000 of SPI options and restricted stock awards were substituted by awards of Issuer’s restricted stock and options to purchase shares of Issuer’s common stock at $1.00 per share with the options having a term of five years and the restricted stock awards vesting over a period of three years. As a result of the substitution, the Reporting Person was granted a option to purchase 100,000 shares of Issuer’s common stock. The options are exercisable at $1.00 per share, will vest over a period of 3 years and have a term of 5 years. In addition, the Reporting Person also received a substituted performance-based options to purchase 100,000 shares of Issuer common stock, which options will vest at either 0% or 100%, such vesting to be determined on December 31, 2010 (the

“Determination Time”). The vesting determination will be based on certain annual revenue performance goals of the Company. The performance goals will be determined on a cumulative basis at the Determination Time, to account for any year-to-year discrepancies in meeting each annual performance goal.

The Merger Agreement, as amended, was attached as Exhibits 10.1 to the Issuer’s Forms 8-K filed on August 29, October 10, December 6 and December 22, 2006, and is incorporated herein by reference.

Item 4. Purpose of the Transaction.

The Reporting Person acquired the Shares (described in Item 3 above) for investment purposes in connection with the Merger pursuant to the Merger Agreement.

In anticipation of the Merger described in Item 3, prior to the Merger Mr. Kircher was appointed as a director and as Chairman of the Board of the Issuer effective as of September 5, 2006, to fill an existing vacancy. Effective upon the Merger, pursuant to the Merger Agreement Mr. Kircher remained a director of the Issuer and was appointed as the Issuer’s Chief Executive Officer while the remainder of the Issuer’s directors and officers resigned their positions. Concurrently, to fill vacancies created by such resignations, the current officers and directors of SPI were appointed to the same respective positions of the Issuer and together with the Reporting Person assumed management control of the Issuer. Although there is no present intention to change the Issuer’s number of authorized directors, the Reporting Person reserves the right, along with the other directors, to identify and appoint such qualified candidate(s) to the Issuer’s Board of Directors, as may be deemed appropriate now or in the future.

In addition, as a condition to the Merger, Issuer changed its corporate name from Welund Fund, Inc. to its current name. Effective October 5, 2006 the Issuer filed a certificate of amendment with the Nevada Secretary of State effecting the name change. Furthermore, as a result of the Merger, the Issuer discontinued its business relating to the pool of finance receivables and commenced its new business and operations in the solar power business.

The Reporting Person, subject to and depending upon availability of prices he deems favorable, may purchase additional Shares of the Issuer from time to time in the open market or in privately negotiated transactions with third parties. Further, while it is not the present intention of the Reporting Person to do so, he reserves the right to dispose of the Shares held by him in the open market or in privately negotiated transactions with third parties or otherwise, depending upon market conditions and other factors.

Subject to ongoing evaluation, except as set forth above, the Reporting Person has no current plans or proposals which relate to or would result in any of the following:

(a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;

(b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;

(d) Any change in the present Board of Directors or management of the Issuer, 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 Issuer;

(f) Any other material change in the Issuer's business or corporate structure including, but not limited to, if the Issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940;

(g) Changes in the Issuer’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;

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

(i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended, or

(j) Any action similar to any of those enumerated above.
