Item 4. Purpose of Transaction

This amendment to Schedule 13D is being filed to report proposed actions by Ms. May and Jericho which would result in a change to the structure and composition of the current Board of Directors of Bigmar. Item 4 is therefore amended by adding the following statement:

On August 15, 2001 Jericho and Ms. May, acting in concert with another shareholder, increased the size of the board, and appointed four new directors to fill the resulting vacancies.

Item 5. Interest in Securities of the Issuer

(a) and (b) Jericho owns beneficially 6,423,539 shares of Bigmar Common Stock. These shares include (i) a Common Stock Warrant for the purchase of 500,000 shares at a price of $5.00 per share, (ii) a Preferred Stock Warrant for the purchase of 1,000,000 shares at a price of $2.5625 per share, and (iii) 4,923,539 shares of Common Stock. In the aggregate, assuming exercise of the Warrants, Jericho may thus be deemed the beneficial owner of approximately 55% of the aggregate of (i) the 10,168,973 shares of Bigmar Common Stock outstanding on August 13, 2001 (as reported on Bigmar’s Quarterly Report on Form 10-Q for the quarterly period ending June 30, 2001) plus (ii) the 1,500,000 shares issuable on exercise of the Warrants.

Cynthia May, owns beneficially 6,607,805 shares of Bigmar Common Stock. These shares include, (i) 4,923,539 shares of Bigmar Common Stock held of record by Jericho, over which Ms. May has investment and dispositive power, (ii) the Common Stock Warrant held by Jericho for the purchase of 500,000 shares of Bigmar Common Stock, (iii) the Preferred Stock Warrant held by Jericho for the purchase of 1,000,000 shares of Bigmar Preferred Stock, and (iv) 184,266 shares of Bigmar Common Stock held of record by GRQ, over which Ms. May has investment and dispositive power. In the aggregate, assuming exercise of the Warrants by Jericho, Ms. May would thus be deemed the beneficial owner of approximately 56.6% of (i) the 10,168,973 shares of Bigmar Common Stock outstanding on August 13, 2001 (as reported on Bigmar’s Quarterly Report on Form 10-Q for the quarterly period ending June 30, 2001) plus (ii) the 1,500,000 shares issuable on exercise of the Warrants.

Based on a form 13G filed with the SEC by John Tramontana on February 10, 1999, Mr. Tramontana, a member of Jericho and the Chief Executive Officer of Bigmar was the beneficial owner of 1,285,800 shares of Bigmar Common Stock (which includes 250,000 shares issuable upon exercise of options). The Reporting Persons have not sought to independently verify Mr. Tramontana’s holdings.

Except as set forth above, neither Cynthia May nor Jericho nor, to the best of Jericho’s knowledge, any of the individuals named in Schedule I hereto, is the beneficial owner of Bigmar Common Stock.

After reasonable inquiry and to the best of its knowledge and belief, the undersigned certifies that the information set forth in this statement is true, complete and correct.
