(a)  Resignation of Registrant’s Certifying Accountant

Effective January 28, 2008, Mantyla McReynolds LLC (“Mantyla McReynolds”) resigned as the Company’s certifying independent accountant engaged to audit its financial statements. Mantyla McReynolds was engaged as auditors to the Company for the year ended December 31, 2006.

Mantyla McReynolds’ report on the Company’s financial statements for the fiscal year ended December 31, 2006 did not contain any adverse opinions or disclaimers of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except for a going concern opinion expressing substantial doubt about the ability of the Company to continue as a going concern.

 Prior to their resignation, there were no disagreements with Mantyla McReynolds on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Mantyla McReynolds would have caused them to make reference to this subject matter of the disagreements in connection with their report, nor were there any “reportable events” as such term is described in Item 304(a)(1)(iv) of Regulation S-B.

The Company provided Mantyla McReynolds with a copy of this Current Report on Form 8-K on January 28, 2008 and requested Mantyla McReynolds to furnish the Company with a copy of a letter addressed to the SEC (the “SEC Letter”) stating whether they agree with the statements made above by the Company regarding Mantyla McReynolds. The SEC letter is attached as Exhibit 16 to this Form 8-K.

Effective January 28, 2008, Chang G. Park, CPA (“Chang Park”), whose address is 371 E Street, Chula Vista, California 91910-2615, was engaged to serve as the Company’s new certifying accountant to audit the Company’s financial statements.

Prior to engaging Chang Park, the Company had not consulted Chang Park regarding the application of accounting principles to a specified transaction, completed or proposed, the type of audit opinion that might be rendered on the Company’s financial statements or a reportable event, nor did the Company consult with Chang Park regarding any disagreements with its prior auditor on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of the prior auditor, would have caused it to make reference to the subject matter of the disagreements in connection with its reports.

The engagement of Chang Park as the Company’s new certifying independent accountant was approved by the Company’s Board of Directors.
