PROSPECTUS
                      1,960,000 Shares Common Stock

                        CAS MEDICAL SYSTEMS, INC.

     This Prospectus relates to 1,960,000 shares (the "Shares") of Common
Stock, par value $0.004 per share (the "Common Stock") of CAS Medical
Systems, Inc. ("CAS" or the "Company") which are being offered for sale by
certain selling stockholders (the "Selling Stockholders").  See "Selling
Stockholders."  The Company will not receive any of the proceeds from sales
of the Shares by the Selling Stockholders although the Company will receive
proceeds from the exercise of certain options and warrants which are
exercisable by the Selling Stockholders into the Shares.  If all of such
options and warrants are exercised by the Selling Stockholders, the Company
will receive proceeds of $708,545.  The Company intends to use such proceeds
for general corporate purposes.  The Shares may be offered from time to time
by the Selling Stockholders through ordinary brokerage transactions, in
negotiated transactions or otherwise, at market prices prevailing at the
time of sale or at negotiated prices.  See "Plan of Distribution."  The
Company's Common Stock is traded on the over-the-counter market commonly
referred to as the "pink sheets".  On January 26, 1998 the closing bid price
of the Common Stock was $0.75 per share.

     The Selling Stockholders may be deemed to be "Underwriters" as defined
in the Securities Act of 1933, as amended (the "Securities Act").  If any
broker-dealers are used to effect sales, any commissions paid to
broker-dealers and, if broker-dealers purchase any of the Shares as
principals, any profits received by such broker-dealers on the resale of the
Shares may be deemed to be underwriting discounts or commissions under the
Securities Act.  In addition, any profits realized by the Selling
Stockholders may be deemed to be underwriting commissions.  All costs,
expenses and fees in connection with the registration of the Shares will be
borne by the Company.  Brokerage commissions, if any, attributable to the
sale of the Shares will be borne by the Selling Stockholders.

     For information concerning certain factors that should be considered

                               RISK FACTORS
   In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating the Company and its
business before purchasing the Shares offered hereby.

   Dependence on Key Distributor.  Effective October 1, 1997, the Company
entered into a non-exclusive Marketing and Distribution Agreement (the "GC
Agreement") with Graphic Controls Corporation ("Graphic Controls"), pursuant
to which Graphic Controls will sell certain of the Company's neo-natal
specialty products solely to specific large hospital purchasing groups. 
Although it is premature to estimate what percentage of the Company's sales
will be to Graphic Controls, the Company anticipates that sales to Graphic
Controls will constitute a material portion of the Company's revenues during
the term of the GC Agreement.  Due in part to the increasing purchaser
consolidation in the medical instrument marketplace, the termination of the
GC Agreement may have a material adverse effect on the Company's business. 
See "- Competition."  There can be no assurance that the GC Agreement will
not be terminated in accordance with its terms or that it will be renewed
upon expiration.

   Competition.  The Company is engaged in a rapidly evolving field. 
Competition from other medical device companies, diversified healthcare
companies and research and academic institutions is intense and expected to
increase.  Many companies engaged in the medical device sector have
substantially greater financial and other resources and development
capabilities than the Company and have substantially greater experience in
testing of products, obtaining regulatory approvals and manufacturing and
marketing medical devices.  Accordingly, certain of the Company's
competitors may succeed in obtaining approval for products more rapidly than
the Company.  Other companies may succeed in developing and commercializing
products earlier than the Company.  In addition to competing with
universities and other research institutions in the development of products,
technologies and processes, the Company may compete with other companies in
acquiring rights to products or technologies from universities. 
Furthermore, the medical device market is experiencing increasing customer
concentration, due to the emergence of large purchasing groups.  There can
be no assurance that the Company will develop products that are more
effective or achieve greater market acceptance than competitive products, or
that the Company's competitors will not succeed in developing products and
technologies that are more effective than those being developed by the
Company or that would render the Company's products and technologies less
competitive or obsolete.  In addition, there can be no assurance that the
Company will be able to successfully sell to large purchasing groups, which
are increasingly looking to suppliers which can provide a broader range of
products than that offered by the Company.

   Product Liability Exposure.  As a manufacturer of medical diagnostic
equipment, the Company could face product liability claims.  The Company has
no pending product liability claims to date and maintains product liability
insurance in an aggregate amount of $5 million.  There can be no assurance
that such coverage will be adequate to cover any product liability claims
which arise in the future or that product liability insurance will continue
to be available at reasonable prices.  Any product liability judgments or
settlements in excess of insurance coverage could have a material adverse
effect on the Company.


<PAGE>
   Government Regulation.  The Company's business is subject to varying
degrees of governmental regulation in the countries in which it operates. 
In the United States, the Company's products are subject to regulation as
medical devices by the United States Food and Drug Administration (the
"FDA"), as well as by other federal and state agencies.  These regulations
pertain to the manufacturing, labeling, development and testing of the
Company's devices as well as to the maintenance of required records.  An FDA
regulation also requires prompt reporting by all medical device
manufacturers of an event or malfunction involving a medical device where
such device caused or contributed to death or serious injury or is likely to
do so.

   Federal law provides for several routes by which the FDA reviews medical
devices prior to their entry into the marketplace.  Medical products of the
type currently being marketed and under development by the Company are
subject to regulation under the Food, Drug and Cosmetic Act (the "FDA Act")
as amended in the Medical Device Amendments of 1976 (the "1976 Amendments")
and the 1990 "Safe Medical Devices Act", as well as additional regulations
promulgated thereunder.  Under the 1976 Amendments, the Company must be a
registered device manufacturer and must comply with Good Manufacturing
Practice Regulations for Medical Devices.  In addition, depending upon
product type, the Company must also comply with those regulations governing
the Conduct of Human Investigations, Pre-Market Approval Regulations and
other requirements, as promulgated by the FDA.  The FDA is authorized to
inspect a device, its labeling and advertising, and the facilities in which
it is manufactured in order to ensure that the device is not manufactured or
labeled in a manner which could cause it to be injurious to health.  Under
the 1976 Amendment and the Safe Medical Device Act, the FDA has adopted
regulations which classify medical devices based upon the degree of
regulation it believes is necessary to assure safety and efficacy.  A device
is classified as a Class I, II, or III device.  Class I devices are subject
only to general controls.  Class II devices, in addition to general
controls, are or will be subject to "performance standards."  Most Class II
devices are subject to the 501(k) pre-market notification provision.  In
addition, some Class III devices require FDA pre-market approval before they
may be marketed commercially because their safety and effectiveness cannot
be assured by the general controls and performance standards of Class I or
II devices.  The Company's products are primarily Class II devices.  Several
of them have required FDA notification under Section 510(k) of the FDA Act.

   Satisfaction of clearance or approval requirements may take up to
several years or more and varies substantially based upon the type,
complexity and novelty of the product.  The effect of government regulation
may be to delay marketing of new products for a considerable or indefinite
period of time, to impose costly procedures upon the Company's activities
and to furnish a competitive advantage to larger companies that compete with
the Company.  There can be no assurance that FDA or other regulatory
clearance or approval for any products developed by the Company will be
granted on a timely basis, if at all, or, once granted, that clearances or
approvals will not be withdrawn or other regulatory action taken which might
limit the Company's ability to market its proposed products.  Any such delay
in obtaining or failure to obtain such clearances or approvals would
adversely affect the manufacturing and marketing of the Company's products
and the ability to generate additional product revenue.


<PAGE>
   In foreign countries, the degree of government regulation affecting the
Company varies considerably among countries, ranging from stringent testing
and approval procedures in certain locations to simple registration
procedures in others, while in some countries there is virtually no
regulation of the sale of the Company's products.  In general, the Company
has not encountered material delays or unusual regulatory impediments in
marketing its products internationally.  Establishment of uniform
regulations for European Community nations took place on January 1, 1995. 
The Company believes it will be subject to a single regulatory scheme for
all the participating countries and has taken the necessary steps to assure
ongoing compliance with these new, more rigorous regulations, including
obtaining International Standards Organization certification for its
manufacturing operations which will allow the Company to market products in
Europe with a single registration applicable to all participating countries.

   Challenges to Patents and Proprietary Rights.  The Company relies on a
combination of patents, trade secrets, trademarks and non-disclosure
agreements to protect its proprietary rights.  There can be no assurance
that patent applications filed by the Company will result in the issuance of
patents or that any patents now or hereafter owned by the Company will
afford protection against competitors which develop similar technology. 
There can also be no assurance that the Company's non-disclosure agreements
will provide meaningful protection for the Company's trade secrets or other
proprietary information.  Moreover, in the absence of patent protection, the
Company's business may be adversely affected by competitors who
independently develop substantially equivalent or superior technology.

   It is possible that the Company may need to acquire licenses to, or to
contest the validity of, issued or pending patents of third parties relating
to the Company's technology or to products presently marketed or under
development by the Company.  In addition, there can be no assurance that any
license required under any such patent would be made available to the
Company on acceptable terms, if at all, or that the Company would prevail in
any such contest.

   Risks of Technological Obsolescence.  The areas in which the Company is
developing, distributing, and/or licensing products involve rapidly
developing technology.  Others may develop products which may render
products being developed, distributed or licensed by the Company obsolete or
uneconomical or result in products superior to the Company's products.

   Risks Associated with International Sales.  Since fiscal 1994, the
Company's international sales have grown faster than its sales to any other
market, and accounted for 30.1% of the Company's total net sales for the
1996 fiscal year.  The Company expects that international sales will
continue to constitute a significant portion of its business.  Although the
Company sells its products in United States dollars and is not subject to
significant currency risks, an increase in the value of the United States
dollar relative to foreign currencies in the Company's international markets
could make the Company's products less price competitive in such markets.


<PAGE>
   Significant Influence of Insiders; Potential Anti-takeover Provisions. 
The Company's directors, executive officers and other affiliates
beneficially own approximately 55% of the outstanding Common Stock of the
Company.  As a result, such directors, officers and affiliates will be able
to significantly influence the election of all of the Company's directors
and otherwise influence control of the Company's operations.  The Company's
Board of Directors is also authorized to issue from time to time, without
stockholder authorization, shares of preferred stock, in one or more
designated series or classes.  The Company is also subject to a Delaware
statute regulating business combinations.  Any of these provisions could
discourage, hinder or preclude an unsolicited acquisition of the Company and
could make it less likely that stockholders receive a premium for their
shares as a result of any such attempt.

   Risks of Low-Priced Stock.  Due to the low trading price of the
Company's Common Stock, it could in the future become subject to Rule 15g-9
under the Exchange Act, which imposes additional sales practice requirements
on broker-dealers that sell "penny stocks".  Commission regulations define a
penny stock to be any non-exchange or NASDAQ entity security that has a
market price (as therein defined) of less than $5.00 per share or with an
exercise price of less than $5.00 per share, subject to certain exceptions. 
The Company's Common Stock is currently exempted from penny stock regulation
by virtue of the fact that the Company has net tangible assets in excess of
$2 million.  For transactions covered by penny stock regulations, a
broker-dealer must make a special suitability determination for the
purchaser and have received the purchaser's written consent to the
transaction prior to sale.  For any transaction by a broker-dealer involving
a penny stock, unless exempt, the rules require delivery, prior to any
transaction in a penny stock, of a disclosure schedule prepared by the
Commission relating to the penny stock market.  Disclosure is also required
to be made about commissions payable to both the broker-dealer and the
registered representative and current quotations for the Common Stock. 
Finally, monthly statements are required to be sent disclosing recent price
information for the penny stock held in the account and information on the
limited market in penny stocks.  There can be no assurance that the
Company's Common Stock will continue to qualify for exemption from these
restrictions.  If the Company's Common Stock were subject to the rules on
penny stocks, it may adversely affect the ability of broker-dealers to sell
the Company's Common Stock and may adversely affect the ability of
purchasers in this offering to resell any of the Common Stock acquired
hereby in the secondary market.

   Effect of Current Offering on Stock Price.  Sales of a substantial
number of shares of the Company's Common Stock in the public market
originally issued pursuant to options or warrants could adversely affect the
market price of the Common Stock and may also adversely affect the Company's
ability to raise additional capital.  1,960,000 shares of Common Stock will
have been registered hereby under the Securities Act for resale to the
public.  The Common Stock registered hereby constitutes approximately 18.2%
of the Company's Common Stock.  Historically, the Common Stock has been
thinly traded.  This low trading volume may have had a significant effect on
the market price of the Common Stock, which may not be indicative of the
market price in a more liquid market.


<PAGE>
   Dependence on Key Personnel.  The Company believes that its future
success will depend to a significant extent on the efforts and abilities of
its senior management, in particular Louis P. Scheps, its President and
Chief Executive Officer and Myron L. Cohen, its Executive Vice President. 
The loss of the services of Mr. Scheps or Dr. Cohen could have a material
adverse effect on the Company.

   Limitation of Liability of Officers and Directors.  The Company's
Certificate of Incorporation provides that officers and directors of the
Company will not be personally liable to the Company or its stockholders for
monetary damages resulting from breaches of duty owed to the Company or its
stockholders, including breaches which constitute negligence in the
performance of their duties.  As a result, the rights of the Company and its
stockholders to obtain monetary damages for acts or omissions of officers
and directors will be more limited than they would be in the absence of such
provisions.

   No Anticipated Dividends.  The Company has not paid cash dividends on
its Common Stock since inception, and at this time does not anticipate that
it will pay cash dividends in the foreseeable future.  

                               THE COMPANY

   The Company was organized in 1984 and is engaged in the business of
developing, manufacturing and distributing diagnostic equipment and medical
products for use by adults and children in many areas of the health care
industry.  The Company has developed and is manufacturing a full line of
non-invasive blood pressure monitors, blood pressure cuffs for both adult
and neonatal patients, silver/silver chloride electrodes for neonatal
hospital intensive care units, and a line of disposable products for
neonatal use.  These products are being sold by the Company directly through
its own sales force via distributors and pursuant to original equipment
manufacturer (OEM) agreements in Europe and the United States.  The Company
has agreements to supply its blood pressure monitors, cuffs and electrodes
to companies for distribution in major segments of the international market.
 The Company also has OEM agreements to supply custom versions of its blood
pressure measuring technology in the form of plug-in modules for patient
monitoring systems.  The Company has several other products in various
stages of development which it believes are applicable to both adult and
neonatal/pediatric medicine.  The Company's executive offices are located at
21 Business Park Drive, Branford, Connecticut, 06405 and its telephone
number is (203) 488-6056.


                           RECENT DEVELOPMENTS

Agreement with Graphic Controls

   Effective October 1, 1997, the Company entered into a non-exclusive
Marketing and Distribution Agreement (the "Agreement") with Graphic Controls
Corporation ("Graphic Controls"), pursuant to which Graphic Controls will
sell certain of the Company's neo-natal specialty products solely to
specific large hospital purchasing groups. The Company anticipates that
sales to Graphic Controls will constitute a material portion of the
Company's revenues during the term of the Agreement.

Common Stock

   Holders of Common Stock of the Company are entitled to one vote per
share on all matters submitted to a vote of the stockholders, including the
election of directors, and except as otherwise required by law or as
provided in any resolution adopted by the Board of Directors with respect to
any series of Preferred Stock, the holders of such shares will exclusively
possess all voting power.  The Company's certificate of incorporation does
not provide for cumulative voting for the election of directors.  Subject to
the preferential rights of any outstanding series of Preferred Stock, the
holders of Common Stock will be entitled to such dividends as may be
declared from time to time by the Board of Directors from funds legally
available therefor, and will be entitled to receive pro rata all assets of
the Company available for distribution to such holders upon liquidation.  No
shares of the Common Stock have any preemptive, redemption or conversion
rights or the benefits of any sinking fund.  All outstanding shares of
Common Stock are validly issued, fully paid and nonassessable.

                           PLAN OF DISTRIBUTION

   The Company is registering the Shares on behalf of the Selling
Stockholders.  All costs, expenses and fees in connection with the
registration of the Shares offered hereby will be borne by the Company. 
Brokerage commissions, if any, attributable to the sale of Shares will be
borne by the Selling Stockholders.

   Sales of Shares may be effected from time to time in transactions (which
may include block transactions) on the over-the-counter market, in
negotiated transactions, or a combination of such methods of sale, at fixed
prices, at market prices prevailing at the time of sale, or at negotiated
prices.  The Selling Stockholders have advised the Company that they have
not entered into any agreements, understandings or arrangements with any
underwriters or broker-dealers regarding the sale of their securities.  The
Selling Stockholders may effect such transactions by selling Shares directly
to purchasers or to or through broker-dealers which may act as agents or
principals.  Such broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Stockholder and/or
the purchasers of Shares for whom such broker-dealers may act as agents or
to whom they sell as principal, or both (which compensation as to a
particular broker-dealer might be in excess of customary commissions).  The
Selling Stockholders and any broker-dealers that act in connection with the
sale of the Shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act and any commission received by them
and any profit on the resale of the Shares as principal might be deemed to
be underwriting discounts and commissions under the Securities Act.  The
Selling Stockholders may agree to indemnify any agent, dealer or
broker-dealer that participates in transactions involving sales of the
shares against certain liabilities, including liabilities arising under the
Securities Act.  Liabilities under the federal securities laws cannot be
waived.

   Because the Selling Stockholders may be deemed to be "underwriters"
within the meaning of Section 2(11) of the Securities Act, the Selling
Stockholders will be subject to prospectus delivery requirements under the
Securities Act.  Furthermore, in the event of a "distribution" of the
shares, such Selling Stockholder, any selling broker or dealer and any
"affiliated purchasers" may be subject to Regulation M under the Exchange
Act, which Regulation would prohibit, with certain exceptions, any such
person from bidding for or purchasing any security which is the subject of
such distribution until his participation in that distribution is completed.
 In addition, Regulation M also prohibits any bid or purchase for the
purpose of pegging, fixing or stabilizing the price of Common Stock in
connection with this offering.

                              LEGAL MATTERS

   Certain legal matters with respect to the validity of the Shares offered
hereby have been passed upon for the Company by Wiggin & Dana, New Haven,
Connecticut.

ITEM 17.   Undertakings.

   (a)  The undersigned registrant hereby undertakes:

   (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

        (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

        (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement;

        (iii)  To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

   Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

   (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

   (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the
termination of the offering.

   (b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

   (h)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions described
under Item 15 above, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification
is against public policy expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in
the successful


<PAGE>
defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.

   (i)  The undersigned registrant hereby undertakes that:

   (1)  For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part
of this registration statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
registration statement as of the time it was declared effective.

   (2)  For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to
the securities offered therein, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof.

            to Graphic Controls at no cost to CAS.  Warehousing conditions
            shall be such that the quality and appearance of the Products
            is not adversely affected and the safety and efficacy of the
            Products is not impaired.

      5.4   Shipping.  Products shall be shipped to Graphic Controls F.O.B.
            CAS.  After the first six (6) months of the Initial Term, CAS
            shall ship the Products no later than four (4) weeks after the
            date CAS receives an Order.  In the event that the Products
            require special shipping, handling, storage, security and
            safety, CAS shall notify Graphic Controls of such requirements.
             Shipments will be made in exact order quantities unless
            otherwise agreed to in writing by the parties. Graphic
            Controls' acceptance of a shipment does not imply acceptance of
            the entire lot. Graphic Controls shall notify CAS of
            discrepancies in shipment or pricing within thirty (30) days
            following receipt of invoice.  Subject to applicable lead times
            set forth herein, if CAS anticipates, at the time it receives
            an Order, that it will be unable to deliver a Product by the
            requested shipment date, CAS will promptly request consent from
            Graphic Controls to an extension of time for shipment, which
            consent shall not be unreasonably withheld.   If CAS does not
            make such request, Graphic Controls may cancel the Order
            without any liability to Graphic Controls.  Any premium freight
            charges, required by any late shipment, are CAS'
            responsibility.

      5.5   Product Marking and Packaging.

            (a)   Marking.  If applicable, CAS will mark either a lot code
                  or a serial number on any Product or packaging and
                  document the procedure to allow for ease in traceability.
                   If applicable, CAS shall also mark the expiration date
                  on each Product.  CAS shall notify Graphic Controls of
                  the procedure detailing the assignment and control of
                  this process.

            (b)   Packaging.  CAS shall use its standard packaging and
                  labels with all of the Products.  Such packaging and
                  labels shall comply with applicable requirements of
                  common carriers.  Graphic Controls may request CAS'
                  consent to modifications or additions to such standard
                  packaging and labels (e.g. bar codes), which consent
                  shall not be unreasonably withheld.  Any such
                  modifications or additions to the packaging and labels
                  shall be made by CAS at the sole expense of Graphic
                  Controls. Any material damage to any Products not
                  packaged as such, will be charged to CAS, provided such
                  packaging is not altered or modified by Graphic Controls
                  or a third party prior to shipment to a member hospital
                  of a Specified Account.

      5.6   Payment Terms.  Contemporaneously with the delivery of the
            Products pursuant to an Order, CAS will invoice Graphic
            Controls for the total price of such Products and corresponding
            freight charges with CAS' standard discount option (1.0% 10
            day/net 30).  Graphic Controls will pay the amount invoiced
            within thirty (30) days of receipt of invoice. Interest shall
            accrue on all past due invoices at the lesser of: (a) 1.5% per
            month (or any part thereof), or (b) at the highest rate allowed
            by U.S. law.  Invoices shall be mailed to Accounts Payable,
            Attention: Diane Wetzel, Graphic Controls Corporation, P.O. Box
            1271, Buffalo, NY 14240.  All invoices shall contain reference
            to applicable purchase order number, CAS part numbers, Graphic
            Controls' part numbers, quantity, price and date shipped.

      5.7   Other Terms and Conditions.  Except as provided in this
            Agreement, all purchases hereunder shall be subject to CAS'
            then current standard written terms and conditions as set forth
            in Exhibit B, attached hereto.  Where such terms and conditions
            conflict in any way with any terms and conditions contained in
            this Agreement, the terms and conditions of this Agreement
            shall prevail.

6.    Trademarks

      Graphic Controls acknowledges that any goodwill or other benefit
      arising from the prior use or continued use in the future of any CAS
      trademarks has inured and will continue to solely inure to the
      benefit of CAS.  Neither Graphic Controls, any affiliates or any of
      their directors, officers, employees or agents shall at any time,
      either during the term of this Agreement or at any time hereafter,
      directly or indirectly contest, or aid others in contesting, or do
      anything which might impair the validity of, any or all of the CAS
      trademarks or the exclusive use thereof by CAS.  Graphic Controls
      shall not remove or otherwise impair any CAS trademarks displayed on
      the packages and labels of the Products.  Graphic Controls shall not
      acquire any right to or under any trademark, patent, copyright,
      design, goodwill or other intellectual property rights of CAS.  If
      any such rights should become vested in Graphic Controls by operation
      of law or otherwise, Graphic Controls agrees that it will, on CAS'
      request, forthwith assign any or all such rights to CAS.  Graphic
      Controls shall immediately notify CAS of any unauthorized use of CAS'
      trademarks and any adverse uses of marks which are confusingly
      similar to any CAS trademarks.

7.    Confidential Information.

      7.1   Nondisclosure.  Each party agrees not to disclose to any third
            party or to use any information obtained from the other party
            concerning the Products (including their design, manufacture
            and operation) and the business, operations, intellectual
            property or financial status of the other party (including
            without limitation, sales forecasts, customer information,
            manufacturing processes, orders and financial statements),
            without the prior written consent of the other party, except
            (i) information generally available to the public without
            breach of this Agreement, (ii) information developed


<PAGE>

            independently by the receiving party, (iii) information
            obtained from a third party not under any obligation of
            nondisclosure, and (iv) information required to be disclosed by
            law or governmental regulation; provided, however, that before
            making any use or disclosure in reliance on (iv), the party
            that intends to use or disclose such information shall give at
            least fifteen (15) days prior written notice to the other party
            specifying the circumstances giving rise thereto.  Each party
            shall protect all information received from the other party and
            marked as "Confidential" in a manner similar to the protection
            it provides to its own confidential information.  Each party
            shall make commercially reasonable efforts to insure that all
            affiliates as well as directors, officers, employees, agents
            and representatives of the party and its affiliates comply with
            this section 7.1.  To the extent possible, each party shall
            disclose the information obtained from the other party to only
            those directors, officers, employees and agents that have a
            need to know and that have agreed to be bound by the terms of
            this section 7.1.  In the event of the termination or
            expiration of this Agreement, each party agrees to return or
            destroy all information received from the other party that is
            marked as "Confidential,"  and each party shall certify  in
            writing that it has complied with this obligation.

      7.2   Equitable Relief.  Either party may obtain permanent and
            preliminary injunctive or other equitable relief to remedy an
            actual or threatened unauthorized disclosure of confidential
            information, or any unauthorized use of such party's
            proprietary rights.  Both parties agree that such unauthorized
            disclosure or use of such information or proprietary rights
            will cause injury that cannot adequately be compensated through
            money damages.  Both parties agree to the entry of an order for
            equitable remedies in the event of the unauthorized disclosure
            or use of such confidential information or proprietary rights
            or the design and specifications of the Products by the other
            party.  The remedies afforded the parties in this section 7.2
            are cumulative and in addition to those provided by law or
            equity.

8.    Noncompetition.  

      Except for those goods and products which Graphic Controls is
      marketing, selling and distributing on the effective date of this
      Agreement as set forth in Schedule D, attached hereto, Graphic
      Controls represents and warrants that it does not currently market
      neonatal medical care products and that it shall not, or permit any
      person or entity affiliated with it to, directly or indirectly,
      market, distribute or sell any goods orproducts that are the same or 
      similar to or competitive with the Products, without CAS' prior
      written consent.  Except as permitted by the preceding sentence of
      this Section 8 and to the extent permitted by law, during the term of
      this Agreement, Graphic Controls shall not manufacture or sell in the
     


<PAGE>

      Territory any goods or products that are the same or similar to or
      competitive with the Products, acquire the right to market,
      distribute, or license any such goods or products within the
      Territory, or take any action that is adverse to CAS' interests,
      Products, market, goodwill or reputation; provided, however, that if
      Graphic Controls acquires the business or product line of any third
      party which sells products which are similar to or competitive with
      the Products, which are not already listed on Schedule D
      ("Acquisition"), Graphic Controls shall not be in violation of this
      Agreement by virtue of such Acquisition or continuing the sale of
      such products.  In the event of any such Acquisition, CAS shall have
      the right to terminate this Agreement upon six (6) months prior
      notice to Graphic Controls.  Graphic Controls represents and warrants
      to CAS that it has no other actual or potential conflicts of
      interests with CAS nor with its obligations under this Agreement and
      it shall avoid any such other conflicts during the term of this
      Agreement. 

9.    Publicity.  

      Without limiting the confidentiality or nondisclosure provisions of
      this Agreement or any purchase order, sales contract, or other
      document, either party may, with the prior consent of the other
      party, advertise or publish the fact that Graphic Controls has sold
      or has contracted to sell the Products pursuant to this Agreement.

10.   Right of Inspection.    

      10.1  By Graphic Controls.  Graphic Controls, or an authorized
            representative or agent of Graphic Controls, may, upon five (5)
            business days advance notice to CAS and during CAS' normal
            business hours, conduct inspections of CAS' nonproprietary
            facilities and/or Product audits, to insure that the Product
            specifications are being met and that CAS continues to maintain
            an effective quality control system, provided that such
            inspections may not be conducted more than twice in any twelve
            (12) month period commencing on the effective date of this
            Agreement.  When requested by Graphic Controls, CAS will
            provide a "Certificate of Compliance," for each shipment.  CAS
            shall inform Graphic Controls of any Product recall, market
            withdrawal, stock recovery, or any field corrective action of
            Products supplied to Graphic Controls.  If Graphic Controls
            requests corrective action as a result of an inspection or
            incident, CAS shall respond (acknowledgement is sufficient)
            within three (3) business days.

      10.2  By CAS.  CAS, or an authorized representative or agent of CAS,
            may, upon five (5) business days advance notice to Graphic
            Controls and during Graphic Controls' normal business hours,
            conduct inspections of Graphic Controls' facilities, to insure
 


<PAGE>
            that storage and distribution requirements are being met
            regarding the safety and efficacy of the Products, provided
            that such inspections may not be conducted more than twice in
            any twelve (12)  month period commencing on the effective date
            ofthis Agreement.  Graphic Controls shall inform CAS of any
            Product recall, market withdrawal, stock recovery, or any field
            corrective action of CAS products.  If CAS requests corrective
            action as a result of an inspection or incident, Graphic
            Controls shall respond (acknowledgement is sufficient) within
            three (3) business days. 

      10.3  By the FDA.  In the event that an agency or branch of the
            federal government, which is seeking to purchase the Products
            from Graphic Controls, requests an inspection by the FDA of the
            manufacturing facilities and records relative to the Products,
            CAS will permit such an inspection, provided that it receives
            reasonable prior notice and that the inspection is conducted
            during CAS' normal business hours.  Graphic Controls also
            agrees to any FDA inspections of its facilities and records.

      10.4  Product Action and Costs.  Graphic Controls may initiate or
            direct a Product recall, market withdrawal, stock recovery or
            other field corrective action of the Products ("Product
            Action"), provided it has given CAS written notice of its
            intent to initiate or direct such Product Action no later than
            48 hours prior to the initiation or directing of such Product
            Action.  In the event that CAS agrees to indemnify Graphic
            Controls in full for all direct costs associated with any
            Product Action, Graphic Controls shall not initiate or direct
            any such Product Action.  In the event that CAS does not agree
            to provide Graphic Controls with full indemnification and
            Graphic Controls initiates or directs such Product Action, CAS
            shall pay or reimburse Graphic Controls no more than fifty
            (50%) percent of all direct out-of-pocket costs and expenses,
            (excluding lost profits, lost sales or other consequential
            damages as set forth in Section 12.3), incurred by Graphic
            Controls in connection with any Product Action, except if, and
            to the extent that, the negligence or action of Graphic
            Controls with respect  to the storage, marketing, distribution,
            sale and shipment of Products shall give rise to the Product
            Action.

      10.5  FDA Product Action and Costs.  In the event the United States
            Food and Drug Administration ("FDA") initiates or directs a
            Product recall, market withdrawal, stock recovery or other
            field corrective action of the Products ("FDA Product Action"),
            CAS agrees to indemnify Graphic Controls in full for all direct
            costs associated with any such FDA Product Action unless, and
            to the extent that, the negligence or action of Graphic
            Controls with respect  to the storage, marketing, distribution,
            sale and shipment of Products gave rise to the FDA Product
            Action.

      11.1  Maintenance of Books and Records.  While this Agreement is in
            effect, both parties will maintain accurate records and
            accounts from which their respective obligations to the other
            hereunder may be determined.  

      11.2  Graphic Controls' Reports.  Within thirty (30) days after the
            end of each month during the term of this Agreement, Graphic

      12.1  Warranty.  CAS warrants that the Products will be free from
            defects in materials and workmanship upon initial application
            only.  Any Products which fail to conform with CAS' Product
            specifications are considered defective.  Graphic Controls has
            no obligation to pay for any defective Products.   Any Product
            defective in material or workmanship will be repaired or
            replaced at no charge to Graphic Controls.  The obligation of
            CAS hereunder shall be limited solely to repair or replacement
            of defective Products and shall be conditioned upon receipt by
            CAS of written notice of any alleged defects or deficiency
            promptly after discovery by Graphic Controls.  CAS shall have
            no obligation to repair or replace Products damaged by misuse
            by Graphic Controls or a third party or failure of Graphic
            Controls or a third party to provide appropriate customary
            storage and maintenance. 


      12.2  Limitation of Warranty.  THE LIMITED WARRANTY EXPRESSED IN
            SECTION 12.1 ABOVE IS IN LIEU OF ALL OTHER WARRANTIES EITHER
            EXPRESS OR IMPLIED, WHETHER ARISING BY STATUTE, CUSTOM, TRADE,
            OR OTHERWISE, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES
            OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  

      12.3  Limitation of Damages and Remedies.  IN NO EVENT SHALL CAS BE
            LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, DIRECT OR
            INDIRECT DAMAGES INCLUDING BUT NOT LIMITED TO LOST REVENUES,
            PROFITS, BUSINESS OR ANTICIPATED SAVINGS, HOWEVER CAUSED AND
 


<PAGE>
            WHETHER ARISING UNDER CONTRACT, TORT OR OTHER THEORY OF
            LIABILITY.  CAS SHALL NOT BE LIABLE FOR ANY DAMAGES IN EXCESS
            OF THE PAYMENTS CAS RECEIVED IN CONNECTION WITH THE SALE OF THE
            PRODUCTS.  THE LIMITATIONS SET FORTH IN THIS SECTION 12.3 SHALL
            IN NO WAY LIMIT THE REPAIR OR REPLACE REMEDIES EXPRESSLY
            SPECIFIED IN SECTION 12.1 OF THIS AGREEMENT, SUBJECT TO SECTION
            15.1 HEREOF.

      12.4  Return of Products.  Products may be returned to CAS for only
            the following reasons: (a) CAS Order entry error and (b)
            defective Product. Any returns due to Order entry error by CAS
            shall be handled in accordance with CAS' returned goods policy
            set forth in Exhibit B.  Graphic Controls shall immediately
            notify CAS upon discovery of a defective Product.  Graphic
            Controls will accumulate defective Products discovered by
            Graphic Controls or any member of a Specified Account.  
            Disposition of the defective Product will be arranged between
            CAS and Graphic Controls. CAS shall pay directly or reimburse
            Graphic Controls for all costs associated with defective
            Products, including premium freight charges incurred to ship
            the returned defective Products or the replacement Products, if
            mutually agreed to be necessary.  If a member of a Specified
            Account discovers a Product defect, CAS shall be responsible
            for the costs of such defective Product and correcting such
            defect.   

13.  Termination.

      13.1  Termination in the Event of Default. In addition to each
            party's ability to terminate this Agreement in accordance with
            Section 2 of this Agreement and with CAS' ability to terminate
            in accordance with Section 3.4(a) of this Agreement, either
            party may terminate this Agreement upon the occurrence of any
            Event of Default, in accordance with the terms of Section 13.2.

      13.2  Events of Default.

            The following are "Events of Default" hereunder:

            (a)   Except as provided in subsection (b) below, a party
                  commits any material breach of any of the obligations or
                  agreements on its part contained in this Agreement,
                  provided (i) the defaulting party shall have ninety (90)
                  days to cure such breach after receipt of written notice
                  thereof, or, if such default is not of the type
                  susceptible to being cured with diligent effort within
                  ninety (90) days, then within a reasonable time period
                  and provided the defaulting party commences promptly and
                  proceeds diligently to cure such default within such
                  ninety (90) day period.

            (b)   Notwithstanding the foregoing subsection (a), there shall
                  be no opportunity to cure for any breach of either
                  party's obligations under Sections 6, 7 and 8, and in the
       


<PAGE>
                  event of any such breach, termination shall be effective
                  immediately upon receipt of the nonbreaching party's
                  notice to the other.

            (c)   This Agreement shall terminate immediately upon either
                  party ceasing to conduct its business, or making an
                  involuntary assignment of all or a material portion of
                  its assets or its business for the benefit of its
                  creditors, or if a trustee, receiver or administrator is
                  appointed to administer or conduct its assets or business
                  affairs, or if it is adjudged in any legal proceedings to
                  be bankrupt, or if any insolvency proceedings are
                  commenced against it.

      13.3  Effect of Termination.  In the event of termination of this
            Agreement for any reason, in addition to any other obligations
            contained herein:

            (a)   Graphic Controls shall immediately stop selling,
                  advertising and distributing the Products, except as
                  provided in subsection (c) below, and it shall notify all
                  Specified Accounts of such termination;

            (b)   Graphic Controls shall furnish CAS with a list of any
                  orders placed by member hospitals of the Specified
                  Accounts for the Products and accepted by Graphic
                  Controls prior to such termination date.  Such list will
                  be furnished within ten (10) days after the termination
                  date.

            (c)   Graphic Controls shall have the right to fill all such
                  orders from its existing inventory of the Products:

                  (i)   for sixty (60) days following such termination
                        date;   and

                  (ii)  as to the balance or any of Graphic Controls'
                        inventory of the Products after such orders have
                        been filled, CAS shall have the option to buy the
                        whole or any part thereof from Graphic Controls at
                        Graphic Controls' cost or market value, whichever
                        is lower; and

                  (iii) if CAS fails to exercise such option within ten
                        (10) days after receiving written notice of Graphic
                        Controls having filled all such orders, Graphic
                        Controls shall be free to sell any of its existing
                        inventory of the Products.  After such inventory is
                        sold, Graphic Controls shall have no further right
                        to sell any of the Products.




<PAGE>
14.   Meetings.  

      The parties agree to meet at least four times per year, at dates and
      times and in places mutually agreed upon, to discuss any issues that
      have arisen, including without limitation, progress in the sales of
      the Products to Specified Accounts, the addition of new accounts and
      the potential for international sales and distribution of the
      Products.  Each party shall bear its respective costs incurred to
      attend such meetings.

15.   Indemnification. 

      15.1  Indemnification.  CAS agrees, at its sole expense, to defend,
            indemnify and hold Graphic Controls (its affiliates, and their
            directors, officers and employees) harmless from and against
            all costs (including reasonable attorneys' fees) and
            liabilities in connection with any claim, suit or action for
            (a) infringement of any U.S. trademarks, patents, copyrights,
            or other proprietary rights associated with the marketing or
            sale of the Products by Graphic Controls; (b) CAS' failure to
            comply with all federal, state or local laws and regulations
            relating the manufacture and distribution of the Products; (c)
            a Product's failure to comply with any applicable federal,
            state or local laws or regulations; and (d) personal injury or
            property damage resulting from the use of a Product, provided
            Graphic Controls promptly notifies CAS in writing of any such
            claim, suit or action and cooperates in the defense thereof,
            provided further CAS shall have no obligation to Graphic
            Controls for such costs and liabilities relating to
            representations and warranties made by Graphic Controls (its
            affiliates and their directors, officers and employees) in
            connection with the marketing, distribution and sale of the
            Products, which exceed or differ from the representations and
            warranties made by CAS with respect to the Products or any
            tortious act(s) committed by Graphic Controls (its affiliates
            and their directors, officers, employees and authorized
            agents).  Graphic Controls shall have the right to be
            represented in any suit or action by advisory counsel of
            Graphic Controls' selection at Graphic Controls' expense.  CAS
            shall control the defense of any such suit or action and has
            the exclusive authority to settle, terminate or defend same,
            provided that any such settlement or termination does not
            directly and adversely impact Graphic Controls' trademarks,
            patents, or copyrights.  CAS may, in its sole discretion,
            modify any infringing Product so as to make it non-infringing
            or substitute another product for such infringing Product, so
            long as there is no degradation to the safety or efficacy of
            the Products. 

      15.2  Insurance.  Each party shall obtain and maintain during the
            Initial Term and any extensions, as well as for a period of
            three (3) years after termination of this Agreement, sufficient
            insurance, and in particular product liability insurance and
            contractual liability insurance (including the indemnification
            referred to in Section 15.1 above), with appropriate policy


<PAGE>
            limits to cover all reasonable risks associated with the
            performance of its obligations under this Agreement.  Each
            party agrees to name the other as a loss payee, as its
            interests may appear, on all insurance policies contemplated by
            this Agreement and that all policies shall require thirty (30)
            days prior notice to the other party of cancellation.  Each
            party shall provide a Certificate of Insurance as written
            evidence to the other of such coverage.

            construing this Agreement.

      16.3  Force Majeure.  If the performance or observance by either
            party of any of its obligations under this Agreement is
            prevented or hindered, or any failure on the part of either
            party to perform or observe its obligations is caused, by
            government restrictions, fire, strike, or any other event or
            cause outside the reasonable control of such party, then such
            failure shall not constitute a breach of this Agreement,

            other party of the beginning and end of any event of force
            majeure, and shall make every reasonable effort to minimize the

<PAGE>
      16.4   Severability.  If any provision of this Agreement is found by
             any competent authority to be invalid, illegal, or
             unenforceable in any respect for any reason, the validity,
             legality, and enforceability of any such provision in every
             other respect and the remainder of this Agreement shall
             continue in effect so long as it still expresses the intent of
             the parties.  If the intent of the parties cannot thereby be
             preserved, the parties agree to substitute a legally valid
             agreement to meet the same economic and technical objectives
             of this Agreement.

      16.5   Remedies.  All rights and remedies of the parties hereunder
             shall be in addition to all other legal and equitable rights
             and remedies belonging to them and the same shall be deemed to
             be cumulative and not in lieu of such other legal and
             equitable rights and remedies.

      16.6   Waiver.  The failure of any party to enforce any provision of
             this Agreement or exercise any right granted hereby shall not
             be construed to be a waiver of such provision or right nor
             shall it affect the validity of this Agreement or any part
             thereof, nor limit, prevent, or impair in any way the right of
             any party subsequently to enforce such provisions or to
             exercise such right in accordance with its terms.

      16.7   Compliance with Laws.  The parties shall, during the term of
             this Agreement, conduct their business in a highly ethical
             manner and in accordance with all federal, state, and local
             statutes, laws, regulations and customs of the United States,

             States anti-trust  laws, the United States Export
             Administration Regulations, the United States Foreign Corrupt
             Practices Act, the North American Free Trade Agreement and the
             United States Anti-Boycott Regulations, as amended during the
             term of this Agreement and as they apply to the parties'
             activities under this Agreement. 

      16.8   Assignment.  Neither party may assign or sub-contract any of
             its rights, obligations and interests under this Agreement
             without the prior written consent of the other party, provided
             that either party may assign this Agreement to any entity
             acquiring all or substantially all of such party's assets.

      16.9   Entire Understanding; Amendment.  This Agreement forms the
             entire understanding of the parties hereto with respect to the
             subject matters described herein, and supersedes all previous
             agreements, written or oral, and all previous and
             contemporaneous discussions.  The terms of this Agreement may
             only be amended in writing signed by both parties.

      16.10  No Third Party Beneficiaries.  This Agreement shall be
             construed to be for the benefit of and be binding upon the
             parties only, and shall confer no right or benefit to any
             other person or entity.


<PAGE>
      16.11  Independent Contractor.  Graphic Controls is an independent
             contractor.  Nothing in this Agreement shall constitute the
             parties as joint venturers, partners, employees, agents or
             legal representatives of each other.  Each party expressly
             acknowledges that it has no power or authority to create any
             obligation for the other.  

      16.12  Effect of Termination; Survival of Certain Provisions.  The
             termination of this Agreement shall not affect any right or
             claim that shall or may have accrued or arisen prior thereto. 
             The provisions of Sections 6, 7, 13, 15 and 16 shall survive
             termination of this Agreement.

      16.13  Choice of Law.  This Agreement shall be construed in

             American Arbitration Association, by a sole arbitrator. The
             place of any arbitration shall be New Haven, Connecticut.  Any
             judgment upon the reward rendered by the arbitrator may be
             entered by any court having competent jurisdiction thereof.

                                   PART I
ITEM 1.  BUSINESS

The Company

CAS Medical Systems, Inc. ("CAS" or the "Company") was organized in 1984
primarily to serve neonatal and pediatric units in hospitals.  Today, CAS is
engaged in the business of developing, manufacturing and distributing
diagnostic equipment and medical products for use by adults and children in
many areas of the health care industry.

The Company has developed and is manufacturing a full line of non-invasive
blood pressure monitors, blood pressure cuffs for both adult and neonatal
patients, silver/silver chloride electrodes for neonatal hospital intensive
care units, and a line of disposable products for neonatal use.  These
products are being sold by the Company directly through its own sales force
via distributors and pursuant to original equipment manufacturer (OEM)
agreements in Europe and the United States.  The Company has agreements to
supply its blood pressure monitors, cuffs and electrodes to companies for
distribution in major segments of the international market.  The Company also
has OEM agreements to supply custom versions of its blood pressure measuring
technology in the form of plug-in modules for patient monitoring systems.  The
Company has several other products in various stages of development which it
believes are applicable to both adult and neonatal/pediatric medicine.

Narrative Description of Business 

Principal Products and Services

OscilloMate Blood Pressure Monitors

The Company manufactures a complete line of state-of-the-art blood pressure
monitors which it has developed.  Distribution is to the hospital and
professional markets through its sales force and distributors, and through
international distributors and OEM agreements.

Pedisphyg, Safe-Cuff, Tuff-Cuff and PAPERCUFF Blood Pressure Cuffs 

The Company manufactures and sells complete lines of disposable and multi-use
blood pressure cuffs for hospital use.  These cuffs are based on design
criteria developed from scientific studies to ensure the highest degree of
accuracy.  They can be used with all of the blood pressure monitors currently
available in hospitals, thus permitting hospitals to use the Company as a
sales supplier for blood pressure cuffs.

Klear-Trace Electrodes

The Company manufactures and sells prewired, X-ray translucent
electrocardiographic electrodes.  They utilize a conductive solid-gel adhesive
that allows them to remain on the patient for extended periods of time without
causing skin irritation.


<PAGE>

NeoGuard Reflectors, Klear-Temp Disposable Temperature Probes

The Company manufactures and sells thermal reflectors to shield temperature
probes while in use within radiant warmers.  They perform an important role in
maintaining the proper thermal environment for neonatal patients while
assuring that no skin irritation takes place.  Klear-Temp disposable skin
temperature probes are designed to be a standard replacement part in all
incubators and radiant warmers.

NeoGuard Limboard Arm Boards

The Company manufactures and sells a line of neonatal arm boards used to
immobilize and support intravenous sites with minimal patient skin trauma.

The electrodes, arm boards, and reflectors utilize a polymeric solid gel
adhesive, manufactured and sold by the Company, to minimize damage to neonatal
skin.

Sales and Marketing

The Company conducts its sales in the domestic hospital market by means of
exclusive distributors utilizing full time sales personnel.  Sales to
emergency medical services are managed nationwide by a full time sales
manager.  OEM sales and international sales are conducted by personnel located
within the Company.

Domestic sales are conducted by 25 distributors across the country each of
whom has exclusive sales rights in a limited geographic area.  Effective
October 1, 1997, the Company entered into a non-exclusive Marketing and
Distribution Agreement (the "Agreement") with Graphic Controls Corporation
("Graphic Controls"), pursuant to which Graphic Controls will sell certain of
the Company's neo-natal specialty products solely to specific large hospital
purchasing groups.  The Company anticipates that sales to Graphic Controls
will constitute a material portion of the Company's revenues during the term
of the Agreement.

The Company has sales agreements with several distributors internationally. 
These agreements provide for distribution of products within an assigned
territory.  Other agreements are being negotiated to allow for expanded
international distribution. 

The Company sells its non-invasive blood pressure technology, in the form of
sub-assemblies to be joined to multi-parameter hospital monitors, to several
firms operating on both a domestic and international basis.  The Company is in
the process of negotiating other agreements for the use of its technology as
components in other medical monitoring systems.

Competition

The Company competes in the hospital market where there are many suppliers
with greater financial and personnel resources that sell a broad line of
commodity products and have a dedicated selling capability.  The Company's
products are targeted to the neonatal and pediatric intensive care units
segment of the hospital market.  The Company has been supplying competitively
priced, uniquely designed products responsive to this segment in which no
major company currently focuses its total resources.

In both the hospital and emergency medical service markets, the Company's
line of non-invasive blood pressure monitoring equipment has significant
advantages over competitive products.  The equipment is compact, portable,
lightweight and user-friendly.  The monitors maintain a high professional
standard of accuracy and quality in demanding environments such as those
encountered in hospital and transport situations.

With respect to all of its products, the Company competes on the basis of
price, features, product quality, promptness of delivery and customer service.

Customers

During 1997, 1996 and 1995, the Company had sales to one customer which in
the aggregate accounted for approximately 13%, 13% and 12% of sales,
respectively.

Research and Development

In 1997, 1996 and 1995, the Company spent approximately $519,000, $396,000
and $405,000, respectively, on activities relating to the development of new
products and the improvement of existing products.

The Company is building on its base of non-invasive blood pressure technology
by developing a family of next-generation patient-monitoring equipment.

Employees

As of December 31, 1997, the Company had 53 employees of whom 50 were
full-time.  The Company has no collective bargaining agreements and believes
that relations with its employees are good.  The Company maintains employee
benefit plans providing for disability income, life insurance, dental and


<PAGE>

medical and hospitalization coverage.  The Company sponsors a 401K benefit
plan for its employees which generally allows participants to make
contributions by salary deductions up to allowable Internal Revenue Service
limits on a tax-deferred basis and discretionary contributions by the Company.
 The 1997, 1996 and 1995 contributions were $32,260, $31,512 and $28,166,
respectively.

Government Regulation

Medical products of the type currently being marketed and under development
by the Company are subject to regulation under the Food, Drug and Cosmetic Act
(the "FDA Act") as amended in the Medical Device Amendments of 1976 (the "1976
Amendments") the 1990 "Safe Medical Devices Act", and most recently, the new
Quality System Regulation (QSR) which replaces the regulations formerly called
Good Manufacturing Practice (GMP's).

In addition, depending upon product type, the Company must also comply with
those regulations governing the Conduct of Human Investigations, Pre-Market
Approval Regulations and other requirements, as promulgated by the Food and
Drug Administration (FDA).  The FDA is authorized to inspect a device, its
labeling and advertising, and the facilities in which it is manufactured in
order to ensure that the device is not manufactured or labeled in a manner
which could cause it to be injurious to health.

Under the 1976 Amendment and the Safe Medical Device Act, the FDA has adopted
regulations which classify medical devices based upon the degree of regulation
it believes is necessary to assure safety and efficacy.  A device is
classified as a Class I, II, or III device.  Class I devices are subject only
to general controls.  Class II devices, in addition to general controls, are
or will be subject to "performance standards."  Most devices are also subject
to the 501(K) pre-market notification provision.  In addition, some Class III
devices require FDA pre-market approval before they may be marketed
commercially because their safety and effectiveness cannot be assured by the
general controls and performance standards of Class I or II devices.  The
Company's products are mostly Class II devices and several of them have
required FDA notification under Section 510(k) of the FDA Act.

The FDA has the authority to, among other things: deny marketing approval
until all regulatory protocols are deemed acceptable; halt the shipment of
defective products; and seize defective products sold to customers.  Adverse
publicity from the FDA, if any, could have a negative impact upon sales.  To
date, the Company has had no FDA oversight problems, and none are pending to
its knowledge.

Manufacturing and Quality Assurance

The Company assembles its products at its facility in Branford, Connecticut. 
The various components for the products, which include plastic sheeting,
plastic moldings, wire, semi-conductor circuits, electronic and pneumatic
components and power supplies are obtained from outside vendors.  The Company
does not anticipate any difficulties in obtaining the components necessary to
manufacture its products.


<PAGE>

Quality control procedures are performed by the Company at its facility and
occasionally at its suppliers' facilities to standards set forth in the FDA's
"Quality System Regulation".  These procedures include the inspection of
components and full testing of finished goods.  The Company has a controlled
clean environment where the final assembly of single-patient-use products is
conducted.

ISO 9001

In September 1996, the quality system at CAS was certified to ISO 9001/EN
46001 by the accredited notified body, BSI Inc.  This certification recognizes
CAS for its achievement in implementing and maintaining a world class quality
system and prepares CAS for the use of the "CE" mark.  The CE mark will be
required in June, 1998 for medical devices to gain access to the European
Union common market.  The FDA, recognizing the value of a universally accepted
quality system, has patterened its new Quality System Regulation after ISO
9001.  CAS is in full compliance with the new Quality System Regulation.

Backlog

The Company's practice is to ship its products upon receipt of a customer's
order or pursuant to customer-requested ship dates.  On December 31, 1997, the
Company had a backlog of orders from customers for products with requested
ship dates in 1998 totaling approximately $1,188,000 deliverable throughout
1998, as compared to $434,000 as of December 31, 1996.  During the first
quarter of 1998, the Company will fulfill approximately $125,000 of this
backlog.

Trademarks, Patents and Copyrights

Certificates of Registration have been issued to the Company by the United
States Department of Commerce Patent and Trademark Office for the following
marks:  CAS (Registered trademark), Pedisphyg (Registered trademark),
OscilloMate (Registered trademark), NeoGuard (Registered trademark), Tuff-Cuff
(Registered trademark), Limboard (Registered trademark), Klear-Trace
(Registered trademark), and the heart shaped mark for use as a thermal
reflector and the Company's corporate logo.  The Company continues to use the
PAPERCUFF (Trademark) and Safe-Cuff (Trademark) common law trademarks.

The Company filed a patent application on behalf of an employee covering the
method of operation of its blood pressure measurement monitor.  This patent
was issued under Patent Number 4,796,184 and assigned to the Company.  The
Company also holds Patent Number 4,966,992, which covers the design of a blood

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS 

Financial Condition, Liquidity and Capital Resources

    As of December 31, 1997, the Company's cash and cash equivalents totaled
$2,190,345, compared to $1,606,979 at December 31, 1996 (an increase of 36%),
and the Company's working capital totaled $3,346,083 on December 31, 1997,
compared to $2,663,685 on December 31, 1996.  The Company's increased cash
position is due to cash provided by operating activities in 1997.  As a result
of improved liquidity in 1997, the Company was able to internally finance
approximately $138,000 of property and equipment additions as well as make
investments in short-term notes, earning approximately $76,000 for 1997.

    The Company's working capital ratio increased from 3.65 at December 31,
1996 to 5.14 at December 31, 1997.

    At December 31, 1997, the Company had a line of credit with a Connecticut
bank totaling $750,000.  Borrowings under the line of credit bear interest at
prime plus 1.0%.  At December 31, 1997, there were no borrowings outstanding
under this line.

    On July 27, 1994, the Company entered into a new four year licensing
agreement with a major European manufacturer of patient monitors, granting a
nonexclusive license to use the Company's blood pressure technology for a
specific application, and allowing the exchange of technical know-how. During
February 1997, the Company amended the original licensing agreement through
the year 2000.  As part of this agreement, the Company will receive license
fees of $1,500,000 plus royalties, of which $895,000 in license fees has been
received through December 31, 1997.  The manufacturer has the option to extend
the license to the year 2006 and only be liable for royalties.  License fees
are being recognized on a straight line basis over the contract period.

    The Company believes that existing funds together with internally
generated funds from 1998 operations and its existing line of credit
arrangement will provide the Company with adequate liquidity and capital
resources to meet its 1998 financial requirements.

    The Company is currently evaluating new Enterprise Resource Planning
(ERP) software to replace the existing software package.  All ERP software
being evaluated is year 2000 compliant and, if purchased, should be in
operation by November 1998.

Results of Operations

    1997 Compared to 1996

    The Company earned $665,000 ($.07 per common share assuming dilution) in
1997, compared to $905,714 ($.09 per common share assuming dilution) in 1996. 
The 1997 earnings performance was impacted by softness in sales of certain of
the Company's product lines and increased personnel in the sales and research
development departments.


    The Company's revenues were approximately $6,901,000 for 1997, a decrease
of approximately $286,000 for the comparable period of 1996.  The decrease in
1997 is due primarily by softness in sales of non-invasive blood pressure 
modules to Original Equipment Manufacturers ("OEM") who utilize the Company's
technology in their systems. 

    Total cost of product sales as a percentage of net product sales was 42.7
percent for 1997 compared to 43.7 percent for 1996.  The favorable impact of
product cost improvements is the result of added production efficiency and
product cost reductions.

    Research and product development (R&D) expenses increased by 31 percent or
approximately $123,000 to approximately $519,000 for the year ended December
31, 1997.  The increase during 1997 is due primarily to additional personnel
in conjunction with the Company's product development objectives.

    Selling, general and administrative expenses were approximately
$2,502,000 in the year ended December 31, 1997 compared to approximately
$2,273,000 in the prior year, an increase of 10 percent. The overall increase
in 1997 is the result of additional sales personnel, both domestic and abroad.

    The Company currently invests its excess cash in low-risk, short-term
interest bearing instruments.  During 1997, the Company earned approximately
$76,000 of interest income compared to approximately $37,000 for 1996.

    1996 Compared to 1995

    The Company earned $905,714 ($.09 per common share assuming dilution) in
1996, compared to $849,000 ($.09 per common share assuming dilution) in 1995. 
The 1996 earnings performance was favorably impacted by incremental gross
margin generated by higher sales volume and an increase in licensing fee
revenues.

    The Company's revenues for the year ended December 31, 1996 were
approximately $7,187,000 and exceeded the comparable period in 1995 by
approximately $758,000.  Sales of non-invasive blood pressure modules to
Original Equipment Manufacturers ("OEM") who utilize the Company's technology
in their systems and Klear-Trace disposable products, were primarily
responsible for the growth in overall sales revenues. 



<PAGE>
    Total cost of product sales decreased as a percentage of net product
sales from 45.9 percent to 43.7 percent when comparing 1996 to 1995.  The
decrease in cost reflects an on-going quality and cost reduction efforts and a
more profitable product mix.

    Selling, general and administrative expenses were approximately
$2,273,000 for the year ended December 31, 1995 and 1996.  However, as a
percentage of net revenues, 1996 decreased to 31.6 percent from 35.3 percent
in 1995.

    The Company's strong cash position enabled all outstanding debt to be
paid in full and resulted in excess cash.  The Company earned approximately
$37,000 in 1996 from various investment accounts.

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Shareholders and Board of Directors of
CAS Medical Systems, Inc.:


We have audited the accompanying balance sheets of CAS Medical
Systems, Inc. (a Delaware corporation) as of December 31, 1997
and 1996, and the related statements of income, shareholders'
equity and cash flows for each of the three years in the period
ended December 31, 1997.  These financial statements are the
responsibility of the Company's management.  Our responsibility
is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the financial position
of CAS Medical Systems, Inc. as of December 31, 1997 and 1996,
and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

                       NOTES TO FINANCIAL STATEMENTS

                             DECEMBER 31, 1997




(1)   The Company:

      CAS Medical Systems, Inc. (the "Company") is engaged in the business of
      developing, manufacturing and distributing diagnostic equipment and
      medical products for use in the healthcare and medical industry.  These
      products are sold by the Company through its own sales force, via
      distributors and pursuant to original equipment manufacturer agreements
      internationally and in the United States.  The Company's operations and
      manufacturing facilities are located in the United States.  During
      1997, 1996 and 1995, the Company had sales to one customer which in the
      aggregate accounted for approximately 13%, 13% and 12% of sales,
      respectively, and had export sales principally to Europe, including
      licensing fee revenues, of $2,251,702, $2,371,007, and $2,155,748,
      respectively.

(2)   Summary of Significant Accounting Policies:

      Cash and Cash Equivalents

      The Company considers all highly liquid investments with an original
      maturity of three months or less to be cash equivalents.
   
      Property and Equipment-
    
      Property and equipment are stated at cost.  Furniture and     
      equipment are depreciated using the straight-line method based on the
      estimated useful lives of the assets, which range from two to five
      years.  Leasehold improvements are amortized over the life of the
      lease.
    
      Revenue Recognition-
    
      Revenues from product sales are recognized upon passage of title,
      generally upon shipment.  Revenues from licensing fees are recognized
      over the term of the agreement (see Note 5).
    
      Research and Development Costs

      The Company expenses all research and development costs as incurred.

      Net Income per Common Share-
    
      In February 1997, the Financial Accounting Standards Board issued
      Statement of Financial Accounting Standards No. 128, "Earnings Per
      Share ("SFAS No. 128")."  Under SFAS No. 128, primary earnings per
      share ("EPS") has been replaced with Basic EPS, which is calculated by
      dividing net income by the weighted average nunmber of shares of
      commonstock outstanding during the year.  No dilution for any
      potentially dilutive securities is included.  Fully diluted EPS has
      been replaced with Diluted EPS and assumes the conversion of all
      potentially dilutive securities using the treasury stock method.  The
      Company adopted SFAS No. 128 in 1997 and, as required, has applied it
      retroactively to the 1996 and 1995 financial statements.

      As of December 31, 1997, the Company had 1,180,100 options and 750,000
      warrants to purchase shares of common stock outstanding.

      Under SFAS No. 128, the Company's Basic and Diluted EPS are as follows:

                                              1997        1996        1995  

      Net income                             665,043     905,714     848,891

        dilutive securities outstanding    9,979,489  10,228,275   9,894,875

        Dilution                                $.07        $.09        $.09
                                           ---------  ----------   ---------

      Use of Estimates

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates
      and assumptions that affect the reported amounts of assets and
      liabilities and disclosure of contingent assets and liabilities at the
      date of the financial statements and the reported amounts of revenues
      and expenses during the reporting period.  Actual results could differ
      from those estimates.

(3)   Inventories:

      Inventories include costs of materials, labor and manufacturing
      overhead.
  
      Inventories are stated at the lower of first-in, first-out (FIFO) cost
      or market and consist of the following:

                                             1997     1996

           Raw materials                 $459,358    472,761

           Finished goods                  92,165    151,046
                                          _______    _______
                                         $725,121   $759,762
(4)   Debt:

      At December 31, 1997, the Company's line of credit arrangement allowed
      for maximum borrowings of $750,000, all of which was available.  The
      line of credit arrangement expires on August 1, 1998 and bears interest
      at the prime rate (8.25% at December 31, 1997) plus 1%.  During 1997,
      1996 and 1995, the maximum month end borrowings outstanding under  
      this line were $100,000, $100,000 and $50,000, the weighted average
      borrowings were $8,333, $8,333 and $4,167, and the weighted average
      interest rates on amounts outstanding were 9.5%, 9.5% and 10.3%,
      respectively.  The bank has a first security interest in all assets of
      the Company and requires a compensating balance equal to 20% of the
      line of credit ($150,000 at December 31, 1997).

(5)   License Agreements:

      On July 27, 1994, the Company entered into a four year licensing
      agreement (subsequently amended through the year 2000) with a major
      European manufacturer of medical equipment, canceling and superseding a
      prior licensing agreement with this company.  The agreement granted a  
      nonexclusive license to use the Company's blood pressure technology for
      a specific application.  As part of this agreement, the Company will 


<PAGE>
                                    F-10

   receive $1,500,000 plus royalties through the year 2000, of which $885,000
   has been received through December 31, 1997.  The manufacturer has the
   option to extend the license to 2006 for which the Company will earn
   royalties.  License fees from this agreement and deferred revenue of
   $140,000 from the prior license agreement are being recognized over the
   life of the current agreement.

  
(6)Capital Stock:

   Holders of the Series C cumulative preferred stock were entitled to a
   cumulative dividend, payable quarterly, at the annual rate of $10 per
   share.  On July 1, 1995, 2,000 shares of the Company's Series C preferred
   stock were redeemed at $100 per share plus dividends accrued.  On January
   17, 1996, the remaining 3,000 shares of the Company's Series C preferred
   stock were redeemed at $100 per share plus accrued dividends.  Preferred
   dividends of $40,000 were paid on these shares in 1995.
  
(7)Employee Benefit Programs:

   Stock Options-
    
   In December 1984, the Board of Directors and stockholders adopted the 1984
   Employee Incentive Stock Option Plan (the "1984 Plan").  The exercise
   price for common stock issued under the 1984 Plan is to be no less than
   the fair market value of the stock at the grant date of the options. 
   Pursuant to the 1984 Plan, 750,000 shares of common stock have been
   reserved for employee (including officers and directors) purchase.  An
   option granted under the 1984 Plan becomes exercisable in two equal annual
   installments, commencing one year from the date of the grant of the
   option.  Options begin to expire between five and ten years from the date
   of grant, depending on the optionholder's percentage of ownership of the
   Company.  In the event employment is terminated, the employee no longer
   has the right to exercise his or her options unless expressly permitted by
   the Board of Directors.


<PAGE>
                                    F-11

   In June 1994, the Board of Directors and stockholders adopted the 1994
   Employees' Incentive Stock Option Plan (the "1994 Plan").  Pursuant to the
   1994 Plan, 250,000 shares of common stock have been reserved for employee
   (including officers and directors) purchase.  The 1994 Plan is the
   successor to the 1984 Plan and contains provisions which are similar to
   those of the 1984 Plan.

   In 1993, the Company granted a warrant to purchase 750,000 shares of
   common stock to an officer of the Company.  The exercise price ($.31 per
   share) was equal to the fair market value of the stock at the grant date
   of the warrant.  The warrant has no expiration date.

   Statement of Financial Accounting Standard No. 123, "Accounting for
   Stock-Based Compensation ("SFAS No. 123")," encourages, but does not
   require, companies to record compensation cost for stock-based employee
   compensation plans at fair value.  The Company has chosen to continue to
   account for stock-based compensation using the intrinsic value method
   prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
   Stock issued to Employees," and related interpretations.  Accordingly, had
   compensation cost for these plans been determined consistent with SFAS No.
   123, the Company's 1997 and 1996 net income and earnings per share would
   have been reduced to the following pro forma amounts:

   Of the 1,180,100 options outstanding at December 31, 1997, 495,600 have
   exercise prices between $.25 and $.375, with a weighted average exercise
   price of $.34 and a weighted average remaining contractual life of 3.86
   years.  All of these options are exercisable.  659,500 of the options
   outstanding have exercise prices between $.625 and $.93, with a weighted
   average exercise price of $.78 and a weighted average remaining
   contractual life of 5.81 years.  640,750 of these options are exercisable;
   their weighted average exercise price is $.81.  The remaining 25,000
   options have an exercise and weighted average exercise price of $1.25 and
   a weighted average remaining contractual life of 8.5 years.   12,500 of
   these options are exercisable.  The weighted average fair value of options
   granted during 1996 was $.80.  No options were granted in 1997.

   The fair value of each option is estimated on the date of grant using the
   Black-Scholes option pricing model with the following weighted-average
   assumptions used for grants in 1996 and 1995:  risk-free interest rates of
   6.06 and 6.94 percent; expected lives of 10 years; expected volatility of
   74 percent.
    
   Life Insurance-
    
   During 1997, 1996 and 1995, the Company paid life insurance premiums of
   approximately $20,000, $17,000 and $14,000, respectively, for life
   insurance policies on the lives of two officers of the Company.  The
   policies are in the face amounts of $1,000,000 and $650,000.  The
   beneficiaries of $250,000 and $150,000, respectively, of the policies are
   designated by the insured.  The Company is the beneficiary of the balance.
    
   401(k) Plan-
    
   The Company maintains a 401(k) benefit plan for its employees which
   generally allows participants to make contributions by salary deductions
   up to allowable Internal Revenue Service limits on a tax-deferred basis
   and discretionary contributions by the Company.  The 1997, 1996 and 1995
   contributions by the Company were $,32,260, $31,512 and $28,166,
   respectively. 
    
   The Company does not provide other post-retirement or other    
   post-employment benefits.

 (8)  Income Taxes:

   The Company follows Statement of Financial Accounting Standards No. 109,
   "Accounting for Income Taxes" (SFAS 109), which requires the recognition
   of deferred tax assets and liabilities for future tax consequences
   resulting from differences between the book and tax basis of existing   
   assets and liabilities.  In addition, SFAS 109 requires the recognition of
   future tax benefits of net operating loss carryforwards to the extent that
   realization of such benefit is more likely than not.


<PAGE>
                                    F-13

   The 1997 provision for income taxes of $464,000 consists of federal and
   state taxes of $392,000 and $72,000, respectively.  The 1996 provision for
   income taxes of $630,000 consists of federal and state taxes of $535,000
   and $95,000, respectively.  These provisions relate primarily to current
   income taxes.  The 1995 provision for income taxes of $85,000 represents
   state income taxes and is net of tax benefits of net operating loss
   carryforwards utilized of $874,000.  As of December 31, 1995, the Company
   had utilized substantially all of its net operating loss carryforwards. 
   The effective tax rate differs from the federal statutory rate of 34%
   principally because of state income taxes and, in 1995, the utilization of
   net operating loss carryforwards.  The deferred tax assets relate
   primarily to certain inventory related expenses and accured liabilities,
   which are not currently deductible for income tax purposes.

(9)  Commitments and Contingencies:

   Employment Agreements-
    
   The Company is committed under employment agreements with certain officers
   for payments aggregating approximately $276,000 which expire in 1998.
    
   Other Commitments-
    
   Minimum annual rentals under the Company's non-cancelable lease agreement
   covering its principal office space, which expires on December 31, 1998
   and includes escalations for real estate taxes, are $110,000.  Rent
   expense was approximately $116,000, $108,000 and $102,000 for the years
   ended December 31, 1997, 1996 and 1995, respectively.

   The Company hs entered into a contract to build a 24,000 square foot
   office, laboratory and manufacturing facility. The total cost is estimated
   to be approximately $1,800,000.  Through January 23, 1998, approximately
   $55,000 hs been incurred on this project.

ITEM 2  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS                                  

    Liquidity and Capital Resources

    As of March 31, 1998, the Company's cash and cash equivalents
totaled $2,036,832 compared to $2,190,345 at December 31, 1997, and the
Company's working capital totaled $3,435,534 on March 31, 1998,

                Notes to Financial Statements - (Continued)

     At March 31, 1998, The Company had a line of credit with a Connecticut
bank totalling $750,000.  Borrowings under the line bears interest at the
prime rate plus 1.0%.  At March 31, 1998, there were no borrowings outstanding
under this line.

    The Company believes that cash generated from operations and its bank
line of credit will be sufficient to meet the Company's short-term liquidity
needs.

    Results of Operations

    Net income for the first quarter of the current year was approximately
$182,000 ($.02 per common share assuming dilution), compared to $261,000 
($.03 per common share assuming dilution), reported for the first quarter of
1997.  The 1998 earnings performance was impacted by softness in sales of
certain of the Company's product lines and the increased expenses by
additional personnel in the selling department.

    The Company's revenues for the three month period ended March 31, 1998
were approximately $1,755,000 as compared to approximately $1,831,000 for the
comparable period in the prior year.  The small decrease in 1998 is due
primarily by softness in sales of certain (OEM) original equipment
manufacturer contracts, prompted by corporate acquisitons.  The Company was
able to recover most of the loss by obtaining new contracts.

    Total cost of product sales decreased as a percent of net product sales
from 42.3 percent to 39.7 percent when comparing 1998 and 1997.  The decrease
in cost reflects on-going quality and cost reduction efforts and a more
profitable product mix.

     Selling, general administrative, advertising and promotion expenses were
approximately $688,000 for the first quarter of 1998, compared to
approximately $565,000 for the same period of 1997, an increase of $123,000 or
22 percent.  The overall increase in 1998 is the result of additional sales
personnel, which were placed during the second quarter of 1997 and increased
advertising and promotion expenses for 1998.

     The Company currently invests its excess cash in low-risk, short term
interest bearing instruments.  During the three month period ended March 30,
1998, the Company earned approximately $20,000 of interest income compared to
approximately $23,000 for the same period of 1997.

     The provision for income taxes of $120,000 and $174,000 for the three
month period ended March 31, 1998 and 1997, respectively, represents state and
federal income taxes.

     These factors and licensing revenues resulted in net income of
approximately $182,000 for the first quarter of 1998, as compared to net
income of approximately $261,000 for the comparable period in the prior year.

<PAGE>
              Notes to Financial Statements  (Continued)

     Net Income Per Common Share

     In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, "Earnings Per
Share ("SFAS No. 128")."  Under SFAS No. 128, primary earnings per
share ("EPS") has been replaced with Basic EPS, which is calculated by
dividing net income by the weighted average number of shares of common
stock outstanding during the year.  No dilution for any potentially
dilutive securities is included.  Fully diluted EPS has been replaced
with Diluted EPS and assumes the conversion of all potentially dilutive
securities using the treasury stock method.  The Company adopted SFAS
No. 128 in 1997.

     As of December 31, 1997, the Company had 1,180,100 options and
750,000 warrants to purchase shares of common stock outstanding.

     Options to purchase 527,000 shares of common stock at an average
price of $.86 per share were outstanding during the first half of 1998
but were not included in the computation of diluted EPS because the
options exercise price was greater than the average market price of the
common shares.

     Reclassifications

     Certain reclassifications were made to prior year amounts to
conform the current year presentation.

Note 3.  Debt:

At June 30, 1998, the Company had a line of credit with a Connecticut
bank totalling $750,000.  Borrowings under the line of credit bears
interest at the prime rate plus 1.0%.  At June 30, 1998 there were no
borrowings outstanding under this line.  The bank has a first security
interest in all assets of the Company and requires a compensating
balance equal to 20% of the line of credit.

Note 4.  License Agreement:

On July 1994, the Company entered into a four year licensing agreement
with a major European manufacturer of patient monitors, granting a
non-exclusive license to use the Company's blood pressure technology
for a specific application, and allowing the exchange of technical
know-how.  During February 1997, the Company amended the original
licensing agreement through the year 2000.  As part of the agreement,
the Company will receive license fees of $1,500,000 plus royalties, of
which $1,006,000 has been received through June 30, 1998.  The
manufacturer has the option to extend the license to the year 2006 and
only be liable for royalties.  License fees are being recognized on a
straight-line basis over the contract period.

              Notes to Financial Statements  (Continued)

Note 5.  New Facility

The company has entered into a contract to build a 24,000 square foot
office, laboratory and manufacturing facility on 4.6 acres of land in
Branford, Connecticut. the total cost is estimated to be $2,100,000. 
Present plans are to occupy the new facility in late 1998.


ITEM 2  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS 

    Liquidity and Capital Resources

    At June 30, 1998, the Company's cash and cash equivalents totaled
$1,530,618 compared to $2,190,345 at December 31, 1997 and the
Company's working capital totaled $2,970,727 on June 30, 1998, compared
to $3,283,083 on December 31, 1997.  The Company's decreased cash
position is due to the acquisition of 4.6 acres of land to build the
new facility.

    At June 30, 1998, the Company had a line of credit with a
Connecticut bank totaling $750,000.  Borrowings under the line bears
interest at the prime rate plus 1.0%.  At June 30, 1998, there were no
borrowings under the line.

     The Company believes that the cash generated from operations and
its bank line of credit will be sufficient to meet the Company's
short-term liquidity needs.

    Results of Operations

    Net income for the six month period ended June 30, 1998 was
approximately $376,000($0.04 per share assuming dilution), compared to
approximately $364,000 ($0.04 per share assuming dilution), for the
same period of 1997.  Net income for the second quarter of the current
year was approximately $193,000 ($.02 per share assuming dilution),
compared to approximately $103,000  ($0.01 per share assuming
dilution), reported for the second quarter of 1997.  The 1998 earnings
performance was impacted by increased sales of certain of the Company's
product lines, Neoguard (TM), and increased expenses by additional
personnel, both in the selling and research development departments.

     The Company's revenues for the three month period ended June 30,
1998 were approximately $1,872,000 as compared to approximately
$1,611,000 for the comparable period in the prior year.  Revenues for
the six month period ended June 30, 1998 reached approximately
$3,627,000, compared to approximately $3,441,000 of the comparable
period of 1997.  Revenues for 1998 reflects a significant increase of
43 percent for Klear-Trace disposable products whereas diagnostic
equipment sales decreased by 27 percent.


<PAGE>

                Notes to Financial Statements  (Continued)


     Gross profit increased to 59.5 percent from 57.6 percent when
comparing 1998 to 1997.  The increase in gross profit reflects on going
quality and cost reduction efforts and a more profitable product mix.

     Selling, general and administrative, research and development expenses
were approximately $1,654,000 for the six month period ended June 30, 1998
as compared to approximately $1,475,000 for the same period of 1997, an
increase of $179,000 or 12 percent.  This increase in expenses for 1998 is
due primarily to additional personnel both in the selling and research
development departments.

     The Company currently invests its excess cash in low-risk, short term
interest bearing instruments.  During the six month period ended June 30,
1998, the Company earned approximately $64,000 of interest income compared
to approximately $32,000 for the same period of 1997.

     The provision for income taxes of $250,000 and $246,000 for the six
month period ended June 30, 1998 and 1997, respectively, represents state
and federal income taxes.

     These factors and licensing revenues resulted in net income of
approximately $376,000 for the period ended June 30, 1989, as compared to
net income of approximately $364,000 for the comparable period in the prior
year.
