ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Sale and Leaseback Transaction

     On June 18, 2007, CAS Medical Systems, Inc. ("CASMED") entered into
agreements with Davis Marcus Partners, Inc. ("DMP") with respect to the sale and
leaseback of CASMED's headquarters and manufacturing facility located at 44 East
Industrial Road, Branford, Connecticut (the "Property"). The purchase and sale
agreement between CASMED and DMP (the "Purchase Agreement") provides for a
purchase price of $3.0 million. CASMED expects the sale transaction to net
approximately $1.4 million of working capital after taxes and repayment of the
remaining mortgage balance on the Property. The completion of the transaction is
subject to a number of closing conditions and is expected to take place during
the third quarter of 2007.

     The Purchase Agreement requires DMP to make an initial deposit of $50,000
and provides for a forty-five (45) day due diligence period within which DMP may
elect to terminate the Purchase Agreement and reclaim the deposit. If DMP does
not elect to terminate the Purchase Agreement within the 45-day due diligence
period, then it is required to deposit an additional $100,000 and close the
transaction within thirty (30) days of the expiration of the initial 45-day due
diligence period.

     Upon closing of the sale of the Property, CASMED will lease back the
Property for a ten (10) year initial term with the option to extend the term for
two (2) additional successive periods of five (5) years, subject to certain
notice and financial covenants requirements (the "Lease"). The Lease is triple
net, and provides for an annual base rent in years 1-5 of $244,800, and years
6-10 of $268,800, payable monthly. In addition, CASMED is responsible for 100%
of the costs of utilities, insurance, taxes and maintenance expenses, subject to
certain agreed upon maintenance components regarding HVAC, parking areas and
roof, which DMP has agreed to assume at its cost. CASMED will be required to
comply with certain financial covenants throughout the term of the Lease which
covenants will require CASMED to maintain (i) at least $600,000 with a U.S.
banking institution in cash or cash equivalents, which required amount shall
increase by three percent (3%) per annum; and (ii) net current assets of not
less than $3,600,000.

     In addition, CASMED will have a right of first offer to lease any
additional space or building built by DMP on the Property, subject to certain
restrictions. CASMED will also have the right to require DMP to build an
addition or additional building ("Expansion Premises"), subject to certain
restrictions. Upon the delivery of any Expansion Premises, the term of the Lease
would extend for a ten (10) year term. The base rent for the Expansion Premises
shall be the greater of the then prevailing market rent or an amount equal to a
return on actual costs of construction of greater than (i) 250 basis points over
the rate on ten (10) year U.S. Treasury Notes, or (ii) eight percent (8%). Upon
delivery of the Expansion Premises, DMP would assume obligations under CASMED's
existing leases of space at 32 and 34 East Industrial Road, Branford,
Connecticut, in exchange for a payment equal to three (3) months rent and
certain unamortized costs incurred in entering into the existing leases.

     On June 19, 2007, CASMED issued a press release with respect to certain
matters described herein, which press release is attached as Exhibit 99.1
hereto.
