Item 1.01  Entry into a Material Definitive Agreement.
 
On March 7, 2006, Sontra Medical Corporation (the “Company”) completed a financing (the “Financing”) that provided the Company with net proceeds of approximately $1.6 million pursuant to the terms of a Common Stock and Warrant Purchase Agreement, dated as of March 7, 2006 (the “Purchase Agreement”). Under the terms of the Purchase Agreement, investors purchased 4,390,995 shares of the Company’s Common Stock in a private placement at a per share purchase price of $0.40. The investors also received warrants (together with the Placement Agent Warrants, the “Warrants”) to purchase up to 4,390,995 shares of Common Stock. The Warrants are exercisable at a per share price of $0.58 and will expire no later than the fifth anniversary of the issue date. In addition, the Company shall have the right to terminate the Warrants, upon thirty days notice, in the event that the closing price of the Company’s common stock for twenty consecutive trading days is equal or greater than $1.16 per share. The Company intends to use the net proceeds from the Financing for working capital and general corporate purposes. Additional closings of the Financing at which the Company may issue up to 65,359 additional shares of Common Stock and additional warrants to purchase up to 65,359 shares of Common Stock on the same terms as the initial closing may be held through March 17, 2006.
 
The Company agreed to pay to the placement agent for the Financing for its services: (a) a cash fee equal to 7% of the aggregate capital raised by the Company in the Financing from investors introduced to the Company by the placement agent, excluding the proceeds from any Warrant exercises; (b) warrants to purchase a number of shares of Common Stock of the Company equal to 7% of the total number of shares of Common Stock issued to investors introduced to the Company by the placement agent in the Financing, excluding shares of Common Stock to be issued upon Warrant exercises or in connection with the payment of dividends or interest, on the identical terms and conditions (including exercise price) with the Warrants issued to the investors in the Financing; and (c) a $25,000 legal expense allowance.

In the Financing, a trust for the benefit of the children of Michael R. Wigley, Chairman of the Board of the Company, purchased 375,000 shares of Common Stock and Warrants for the purchase of 375,000 shares of Common Stock, for an aggregate purchase price of $150,000.00.
 
The offer, sale and issuance to the investors of the Common Stock, the Warrants and the shares of Common Stock issuable upon the exercise of the Warrants have not been and will not be registered under the Securities Act of 1933, as amended, and, unless so registered, may not be offered or sold in the United States, except pursuant to an applicable exemption from the registration requirements of the Securities Act of 1933, as amended, and applicable state securities laws.
 
The Company is required to register for resale under the Securities Act the shares of Common Stock issued to the investors and the shares issuable upon the exercise of the Warrants. The Company is also required to register under the Securities Act for resale by the placement agent the shares issuable upon the exercise of the Placement Agent Warrants.
 
The foregoing description of the Purchase Agreement and the Warrants and the transactions contemplated therein and thereby does not purport to be complete and is qualified in its entirety by reference to the full text of such agreements and instruments, which are filed as exhibits to this Form 8-K and are incorporated by reference herein.
 
Item 3.02  Unregistered Sales of Equity Securities.
 
On March 7, 2006, the Company completed the Financing and issued an aggregate of 4,390,995 shares of Common Stock at an aggregate purchase price of $1,756,398.00. The Company also issued Warrants to purchase up to 4,390,995 shares of Common Stock, and became obligated to issue the Placement Agent Warrants to purchase up to 307,370 shares of Common Stock. For a further description of the Financing, see Item 1.01 above, which is incorporated herein by reference. The shares of Common Stock, the Warrants and the Placement Agent Warrants were issued and sold in reliance on Section 4(2) of the Securities Act of 1933, as amended, and Rule 506 of Regulation D promulgated thereunder, as a sale by the Company not involving a public offering. No underwriters were involved with the issuance and sale of such securities in the Financing.
