RE:      RESIGNATION FROM BOARD OF DIRECTORS OF BIGMAR, INC.



Dear Mr. Tramontana:

This letter confirms my emailed April 15, 2002 resignation as a member of the
board of directors of Bigmar, Inc., a Delaware corporation ("the Company").

I accepted my appointment to the board with much enthusiasm and anticipation. I
still believe today that I have experience and knowledge of growing a business
and optimizing its organization that would be beneficial to Bigmar or any other
business. Truthfully, had I known the internal problems that engulfed the
company, I would have never volunteered my time and services. What further
complicated our responsibilities and duty was the failure of the company to
produce timely and accurate financial data for the board members to utilize in
making critical decisions. This lack of information made our jobs virtually
impossible to perform.

Regardless of the problems, I still believe the company has great potential, but
in order to reach this potential all attention needs to focus on helping the
company through its financial difficulties. It is critical that the board and
the operating executives of the company unite and focus on one goal, the
company's success. With this goal in mind, I have elected to resign in order to
allow this fresh start to begin.


Very truly yours,


/s/ Timothy K. Carroll
