ITEM 5.03.  AMENDMENTS TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN FISCAL
YEAR

(a)    On November 30, 2007, the Board of Directors of CAS Medical Systems, Inc.
(the "Company") approved amendments to the bylaws of the Company to permit the
Board to provide for the issuance and transfer of uncertificated shares of the
Company's stock. These amendments have been adopted in response to the Nasdaq
Stock Market's requirement that companies be eligible, by January 1, 2008, to
participate in a direct registration system. The direct registration system
would allow shareholders to own and transact shares in electronic (book-entry)
form without the issuance of physical certificates.

       The foregoing description of the amendment to the Company's bylaws does
not purport to be complete and is qualified in its entirety by reference to the
Amended and Restated Bylaws of the Company, a copy of which are filed as Exhibit
3.1 hereto and incorporated herein by reference.
