Item 1.01 Entry into a Material Definitive Agreement.

Item 3.02 Unregistered Sales of Equity Securities.

On February 28, 2012, L&L Acquisition Corp. (the “Company”), in order to fund working capital requirements, issued an unsecured Convertible Promissory Note (the “Note”) in the principal amount of $200,000 to LLM Structured Equity Fund L.P., one of the Company’s sponsors (“LLMSEF”). The Note is non-interest bearing and the principal balance is payable upon the earlier of (i) May 29, 2012 or (ii) the date on which the Company consummates an initial business combination. Pursuant to the Note, LLMSEF shall have no recourse against the Company’s trust account in which the proceeds of its initial public offering and the proceeds of the sale of warrants issued in a private placement (the “Private Placement Warrants”) that occurred simultaneously with the completion of the initial public offering, were deposited.

Subject to the terms of the Note, upon certain events of default, including, but not limited to (i) failure by the Company to pay any principal amount under the Note within five business days following the due date, (ii) the Company’s commencement of a voluntary bankruptcy case or (iii) the entry of an involuntary bankruptcy case in respect of the Company, the unpaid principal balance on the Note will become due and payable.

In the event that the Company enters into a definitive agreement to consummate a business combination, LLMSEF, at its option, may convert the then outstanding principal amount of the Note into warrants of the post-business combination entity, at a price of $0.75 per warrant. These warrants would be issued in reliance upon exemptions from the registration provisions of the Securities Act of 1933, as amended, set forth in Section 4(2) thereof relative to sales by an issuer not involving any public offering. The terms of such warrants would be identical to the terms of the Private Placement Warrants, including, but not limited to, that each warrant would entitle LLMSEF to purchase one share of common stock of the post-business combination entity at $11.50 per share. The maximum amount of common stock that may be issued through the exercise of warrants (based on the conversion of the entire $200,000 principal amount of the Note) by LLMSEF would be 266,667 shares at an aggregate purchase price of approximately $3,066,670.

The foregoing summary of the Note is qualified in its entirety by reference to the full text of such Note, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference thereto.
