ITEM 2.01.  COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS

Closing of Sale and Leaseback Transaction

     On September 6, 2007, CAS Medical Systems, Inc. ("CASMED") closed the
previously announced sale and leaseback of its headquarters and manufacturing
facility located at 44 East Industrial Road, Branford, Connecticut (the
"Property"). On June 18, 2007, CASMED entered into agreements with Davis Marcus
Partners, Inc. with respect to the sale and leaseback of the Property. The
purchase and sale agreement between CASMED and Davis Marcus Partners, Inc. (the
"Purchase Agreement") resulted in the payment to CASMED at closing of a purchase
price of $3.0 million and the sale transaction resulted in a net to CASMED of
approximately $1.4 million of working capital after taxes and repayment of the
remaining mortgage balance on the Property.

     On September 6, 2007, CASMED entered into a Lease with DMP New Branford,
LLC ("DMP") pursuant to which it is leasing 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 is 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 has a right of first offer to lease any additional
space or building built by DMP on the Property, subject to certain restrictions.
CASMED also has 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 will 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.

     The foregoing descriptions of the Purchase Agreement and the Lease do not
purport to be complete and are qualified in their entirety by reference to these
agreements, copies of which are filed as Exhibits 2.1 and 10.1 hereto,
respectively, and incorporated herein by reference.
