                               RISK FACTORS

   You should carefully consider the risks described below before making an
investment decision.  The risks and uncertanties described below are not the
only ones facing our company.  Additional risks and uncertanties of which we
are unaware or that we currently think are immaterial may also impair our
business operations.  If any of the following risks actually occur, our
business, financial condition or results of operations could be materially
adversely affected.  This could cause the trading price of our common stock
to decline, and you could lose all or part of your investment.

   COMPETITION.  We are 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 we
do and have substantially greater experience in testing of products,
obtaining regulatory approvals and manufacturing and marketing medical
devices.  Therefore, our competitors may succeed in obtaining approval for
products more rapidly than we can.  Other companies may succeed in
developing and commercializing products earlier than we do.  In addition to
competing with universities and other research institutions in the
development of products, technologies and processes, CAS Medical may compete
with other companies in acquiring rights to products or technologies from
universities.  Also, the medical device market is experiencing increasing
customer concentration, due to the emergence of large purchasing groups.  We
cannot assure you that we will develop products that are more effective or
achieve greater market acceptance than competitive products, or that our
competitors will not succeed in developing products and technologies that
are more effective than those being developed by us or that would render our
products and technologies less competitive or obsolete.  Moreover, there can
be no assurance that we will be able to successfully sell to large
purchasing groups, which are increasingly looking to suppliers that can
provide a broader range of products than we currently offer.

   PRODUCT LIABILITY EXPOSURE.  As a manufacturer of medical diagnostic
equipment, we could face product liability claims.  We have no pending
product liability claims and maintain product liability insurance in an
aggregate amount of $5 million.  We cannot assure you that this insurance
coverage will be adequate to cover any product liability claims that occur
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 our business and results of operations.


<PAGE>
   GOVERNMENT REGULATION.  Our business is subject to varying degrees of
governmental regulation in the countries in which we operate.  In the United
States, our 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 our 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 before their entry into the marketplace.  Medical products of the
type currently being marketed and under development by us 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.  Under
the 1976 Amendments, we must be a registered device manufacturer and must
comply with Good Manufacturing Practice Regulations for Medical Devices.  In
addition, depending upon product type, we must also comply with those
regulations governing the Conduct of Human Investigations, Pre-Market
Approval Regulations and other requirements, as determined 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.  Our 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 may vary 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
us.  We cannot assure you that FDA or other regulatory clearance or approval
for any products we develop 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 our ability to market our
proposed products.  Any delay in obtaining or failure to obtain such
clearances or approvals would adversely affect the manufacturing and
marketing of our products and the ability to generate additional product
revenue.


<PAGE>
   In foreign countries, the degree of government regulation affecting our
business varies considerably among countries, ranging from stringent testing
and approval procedures in some locations to simple registration procedures
in others, while in some countries there is virtually no regulation of the
sale of our products.  In general, we have not encountered material delays
or unusual regulatory impediments in marketing our products internationally.
 Establishment of uniform regulations for European Union nations recently
took place.  We believe that we will be subject to a single regulatory
scheme for all the participating countries and we have taken the necessary
steps to assure ongoing compliance with these new, more rigorous
regulations, including obtaining International Standards Organization
certification for our manufacturing operations.  This will allow us to
market products in Europe with a single registration applicable to all
participating countries.

   CHALLENGES TO PATENTS AND PROPRIETARY RIGHTS.  We rely on a combination
of patents, trade secrets, trademarks and non-disclosure agreements to
protect our proprietary rights.  We cannot assure you that our patent
applications will result in the issuance of patents or that any patents
owned by the Company now or in the future will afford protection against
competitors that develop similar technology.  We also cannot assure that the
our non-disclosure agreements will provide meaningful protection for our
trade secrets or other proprietary information.  Moreover, in the absence of
patent protection, our business may be adversely affected by competitors who
independently develop substantially equivalent or superior technology.

   It is possible that we may need to acquire licenses to, or to contest
the validity of, issued or pending patents of third parties relating to our
technology or to products presently marketed or under development by us. In
addition, we cannot assure that any license required under a patent would be
made available to us on acceptable terms, if at all, or that we would
prevail in any patent litigation.

   RISKS OF TECHNOLOGICAL OBSOLESCENCE.  The areas in which we are
developing, distributing, and/or licensing products involve rapidly
developing technology.  Others may develop products that might cause
products being developed, distributed or licensed by us to become obsolete
or uneconomical or result in products superior to our products.

   RISKS ASSOCIATED WITH INTERNATIONAL SALES.  In recent years, our
international sales have grown faster than our domestic sales, and accounted
for 30% of our total net sales for the 1998 fiscal year.  We expect that
international sales will continue to constitute a significant portion of our
business.  Although we sell our products in United States dollars and are
not subject to significant currency risks, an increase in the value of the
United States dollar relative to foreign currencies in our international
markets could make our products less price competitive in these markets.


<PAGE>
   SIGNIFICANT INFLUENCE OF INSIDERS; POTENTIAL ANTI-TAKEOVER PROVISIONS.
Our directors, executive officers and other affiliates beneficially own
approximately 55% of the outstanding common stock of CAS Medical.  As a
result, these directors, officers and affiliates will be able to
significantly influence the election of all of our directors and otherwise
influence control of the our operations.  Our 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.  We
are also subject to a Delaware statute regulating business combinations.
Any of these provisions could discourage, hinder or preclude an unsolicited
acquisition of CAS Medical and could make it less likely that stockholders
receive a premium for their shares as a result of any takeover attempt.

   RISKS OF LOW-PRICED STOCK.  Due to the low trading price of our common
stock, it could in the future become subject to Rule 15g-9 under the
Securities Exchange Act of 1934, which imposes additional sales practice
requirements on broker-dealers that sell "penny stocks".  SEC regulations
define a penny stock to be any non-exchange or NASDAQ entity security that
has a market price of less than $5.00 per share or with an exercise price of
less than $5.00 per share, subject to some exceptions.  Our common stock is
currently exempted from penny stock regulation by virtue of the fact that we
have 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 SEC 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.  We cannot assure
that our common stock will continue to qualify for exemption from these
restrictions.  If the our common stock were subject to the rules on penny
stocks, it may adversely affect the ability of broker-dealers to sell the
our common stock and may adversely affect the ability of purchasers in this
offering to resell any of the common stock they purchased in the secondary
market.

   EFFECT OF CURRENT OFFERING ON STOCK PRICE.  Sales of a substantial
number of shares of our common stock in the public market originally issued
through the exercise of options or warrants could adversely affect the
market price of our common stock and may also adversely affect our ability
to raise additional capital.  2,060,000 shares of CAS Medical common stock
are being registered in connection with this prospectus for resale to the
public.  The CAS Medical common stock registered in connection with  this
prospectus constitutes approximately 18.9% of our common stock.
Historically, our common stock has been thinly traded.  This low trading
volume may have had a significant effect on the market price of our common
stock, which may not be indicative of the market price in a more liquid
market.


<PAGE>
   DEPENDENCE ON KEY PERSONNEL.  We believe that our future success will
depend to a significant extent on the efforts and abilities of our senior
management, in particular Louis P. Scheps, our President and Chief Executive
Officer and Myron L. Cohen, our Executive Vice President.  The loss of the
services of Mr. Scheps or Dr. Cohen could have a material adverse effect on
our business and results of operations.

   LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS.  Our Certificate of
Incorporation provides that our officers and directors will not be
personally liable to CAS Medical or its stockholders for monetary damages
resulting from breaches of duty owed to CAS Medical or its stockholders,
including breaches which constitute negligence in the performance of their
duties.  As a result, the rights of CAS Medical 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.  We have not paid cash dividends on our common
stock since inception, and at this time we do not anticipate that we will
pay cash dividends in the foreseeable future.

                               THE COMPANY

   CAS Medical Systems, Inc. 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.  We have developed and are 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 us directly through our own
sales force via distributors and pursuant to original equipment manufacturer
(OEM) agreements in Europe and the United States.  We have agreements to
supply our blood pressure monitors, cuffs and electrodes to companies for
distribution in major segments of the international market.  We also have
OEM agreements to supply custom versions of its blood pressure measuring
technology in the form of plug-in modules for patient monitoring systems.
We have several other products in various stages of development which we
believe are applicable to both adult and neonatal/pediatric medicine.  Our
executive offices are located at 44 East Industrial Road, Branford,
Connecticut, 06405 and our telephone number is (203) 488-6056.

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

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.


<PAGE>
                           PLAN OF DISTRIBUTION

   We are registering the shares of common stock covered by this Prospectus
for the Selling Stockholders.  We will pay the costs and fees of registering
the shares of common stock covered by this Prospectus, but the Selling
Stockholders will pay any brokerage commissions, discounts or other expenses
relating to the sale of such shares.

   The Selling Stockholders may sell the shares of common stock in the
over-the-counter market or otherwise, at market prices prevailing at the
time of sale, at prices related to the prevailing market prices, or at
negotiated prices. In addition, the Selling Stockholders may sell some or
all of their shares of common stock covered by this Prospectus through:

- -  a block trade in which a broker-dealer may resell a portion of the
   block, as principal, in order to facilitate the transaction;

- -  purchases by a broker-dealer, as principal, and resale by the
   broker-dealer for its account; or ordinary brokerage transactions and
   transactions in which a broker solicits purchasers.

   The Selling Stockholder may negotiate and pay broker-dealers
commissions, discounts or concessions for their services, provided that no
such commissions, discounts or concessions are paid by CAS Medical.
Broker-dealers engaged by the Selling Stockholders may allow other
broker-dealers to participate in resales.  However, the Selling Stockholders
and any broker-dealers involved in the sale or resale of the common shares
may qualify as "underwriters' within the meaning of Section 2(a)(11) of the
Securities Act of 1933 (the "1933 Act").  In addition, the broker-dealers'
commisions, discounts or concessions may qualify as underwriters'
compensation under the 1933 Act.  If any of the Selling Stockholders
qualifies as an "underwriter," the Selling Shareholder wil be subject to the
prospectus delivery requirements of Section 5(b)(2) of the 1933 Act.

   In addition to selling their shares of common stock under this
Prospectus, the Selling Stockholders may:

- -  agree to indemnify any broker-dealer or agent against certain
   liabilities related to the selling of the shares of common stock,
   including liabilities arising under the 1933 Act;

- -  transfer shares of common stock in other ways not involving market
   makers or established trading markets, including directly by gift,
   distribution, or other transfer; or

- -  sell shares of common stock under Rule 144 of the 1933 Act rather than
   under this Prospectus, if the transaction meets the requirements of Rule
   144.



<PAGE>

                             USE OF PROCEEDS

   We will not receive any proceeds from the sale of common stock by the
Selling Stockholders.  If all of the options and warrants exercisable by the
Selling Stockholders into shares being offered in this Prospectus are
exercised by the Selling Stockholders, we will receive proceeds of $808,545.
We intend to use those proceeds for general corporate purposes.

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;

   (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.

   (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 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.


<PAGE>

   (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.




                                SIGNATURES

   Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant certifies that it has reasonable grounds to believe that it

                                   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 sole
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

Domestic sales are conducted by 18 specialty distributors across the country,
each of whom has exclusive sales rights in a limited geographic area and
covers either the hospital arena or emergency medical services.  During 1998,
the Company had a non-exclusive Marketing and Distribution Agreement (the
"Agreement") with Graphic Controls Corporation ("Graphic Controls"), pursuant
to which Graphic Controls sold certain of the Company's neonatal specialty
products solely to specific large hospital purchasing groups.  This Agreement
was mutually terminated by the parties in December 1998.

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 1998, 1997 and 1996, the Company had sales to one customer which in
the aggregate accounted for approximately 13% of sales in each of the three
years reported.

Research and Development

In 1998, 1997 and 1996, the Company spent approximately $548,000, $519,000
and $396,000, respectively, on activities relating to the development of new
products and the improvement of existing products.

The Company wil continue to develop and expand its patient monitoring
capability, by adding new physiological parameters. In addition, plans are in
process to greatly improve information processing within the monitor, using
new screen and communication technology.  This will allow the Company to
significantly increase sales penetration in the Acute and Intensive Care
market.

Employees

As of December 31, 1998, the Company had 58 employees of whom 55 were
full-time.  The Company has no collective bargaining agreements and believes
that relations with its employees are good.


<PAGE>

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 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 is now required
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, 1998, the
Company had a backlog of orders from customers for products with requested
ship dates in 1999 totaling approximately $1,184,000 deliverable throughout
1999, as compared to $1,188,000 as of December 31, 1997.  During the first
quarter of 1999, the Company will fulfill approximately $147,000 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,
issued under Patent Number 4,796,184, was assigned to the Company.  The
Company also holds Patent Number 4,966,992, which covers the design of a blood
pressure monitor for use with hyperbaric chambers. The Company holds Patent
Number 5,101,830, which covers the design of a blood pressure cuff.

The Company has copyright protection for the software used in its blood
pressure monitors.

ITEM 2.  PROPERTIES

During November 1998, the Company relocated to a 24,000 square foot office,
laboratory and manufacturing facility owned by the Company in Branford,
Connecticut.  Total cost of this new facility was approximately $1,933,000.
The Company is the sole tenant of this new facility.

During January 1999, the Company obtained a nineteen year, 7.25% fixed rate
$1,310,000 mortgage from a local bank.  The mortgage is secured by a first
mortgage lien on the Company property consisting of 4.6 acres of land and the
24,000 square foot industrial building.  The estimated payments are
approximately $10,600 per month.  The Company believes that insurance on the
property is adequate.

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

Financial Condition, Liquidity and Capital Resources

    As of December 31, 1998, the Company's cash and cash equivalents totaled
$1,442,342, compared to $2,190,345 at December 31, 1997 (a decrease of 34%),
and the Company's working capital totaled $1,974,600 on December 31, 1998,
compared to $3,283,083 on December 31, 1997.  The Company's decreased cash
position is due to internally financing approximately $1,933,000 for the new
24,000 square foot office, laboratory and manufacturing facility, on 4.6 acres
of acquired land in Branford, Connecticut.  Consequently, the Company's
working capital ratio decreased from 5.14 at December 31, 1997 to 2.31 at
December 31, 1998.

    At December 31, 1998, the Company had a line of credit with a Connecticut
bank totaling $1,000,000.  Borrowings under the line of credit bear interest
at prime plus 1.0%.  At December 31, 1998, 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 $1,100,000 in license fees has
been received through December 31, 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.

    The Company believes that existing funds together with internally
generated funds from 1999 operations and its existing line of credit
arrangement will provide the Company with adequate liquidity and capital
resources to meet its 1999 financial requirements.


<PAGE>

Year 2000 Compliance

    The Year 2000 ("Y2K") issue relates to the inability of information
systems to properly recognize and process date sensitive information beyond
January 1, 2000.  Many computer systems and software products may not be able
to interpret dates after December 31, 1999 because such systems and products
allow only two digits to indicate the year in a date.  As a result, these
systems and products are unable to distinguish January 1, 2000 from January 1,
1900, which could have adverse consequences on the operations of an entity and
the integrity of its information processing.

    The Company's management has recognized the need to address the Year 2000
issue within its internal operational systems as well as with suppliers and
other third parties.  As with many other companies, a significant number of
the Company's information systems have required and will require modification
to render these systems Y2K compliant.  The company recognizes that failure by
the Company to timely resolve internal Y2K issues could result in an inability
of the Company to ship products, to receive raw materials, to pay for
materials received (which could delay delivery of undelivered materials), and
to otherwise process its daily business for an indeterminate period of time,
each of which could materially and adversely affect the Company's financial
conditions and results of operations.  However, the Company's management
presently believes these scenarios are unlikely based on the progress the
Company has made in its Y2K compliance process.

    The Company purchased a new Enterprise Resource Planning (ERP) software
to replace the existing software package and migrate its current MMPII package
onto IBM hardware running Microsoft NT.  This total package is fully year 2000
compliant and the total cost is estimated under $50,000.  The Company is also
surveying all suppliers to determine their compliance with the Y2K issue and
what impact, if any, their efforts will have on the Company's business.

    However, if the Company and third parties, upon which it relies, are
unable to address this issue in a timely manner, it could result in a material
financial risk to the Company. In order to assure that this does not occur,
the Company plans to devote all resources required to resolve any significant
year 2000 issues in a timely manner.

Results of Operations

    1998 Compared to 1997

    The Company earned $816,000 ($.08 per common share on a diluted basis) in
1998, compared to $665,000 ($.07 per common share on a diluted basis) in 1997.
 The 1998 earnings performance was favorably impacted by revenues from a
one-time contract settlement and an increase in licensing fee revenues.

    The Company's revenues for the year ended December 31, 1998 were
approximately $7,020,000 and exceeded the comparable period in 1997 by
approximately $119,000.  Sales revenues for 1998 reflects a significant
increase of 22 percent for Klear-Trace disposable products, whereas diagnostic
equipment sales decreased by 21 percent. This is attributed to the loss of a
few key OEM accounts due to their corporate restructuring.

    Total cost of product sales as a percentage of net product sales was 43.6
percent for 1998 compared to 42.7 percent for 1997.  The slight increase in
cost is due primarily to product mix.

    Research and development expenses increased by 6 percent during 1998 to
approximately $548,000 compared to approximately $519,000 for the same period
of 1997, primarily due to development cost of new products.

    Selling, general and administrative expenses were approximately
$3,011,000 in the year ended December 31, 1998 compared to approximately
$2,502,000 in the prior year, an increase of 20 percent. The increase is due
to the continued growth in personnel in sales and marketing, both domestic and
international.

    The Company currently invests its excess cash in low-risk, short-term
interest bearing instruments.  During 1998, the Company earned approximately
$106,000 of interest income compared to approximately $76,000 for 1997.

    1997 Compared to 1996

    The Company earned $665,000 ($.07 per common share on a diluted basis) in
1997, compared to $906,000 ($.09 per common share on a diluted basis) 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.



<PAGE>

    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.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    The Company and Mr. Scheps have entered into an employment agreement
pursuant to which Mr. Scheps serves as President and Chief Excutive Officer of
the Company.  As of September 1, 1998, the employment agreement was amended
(as amended, the "Employment Agreement") to extend its term through August 31,
2000 and provide for a base salary of $185,000 per year.  The Employment
Agreement also provides that if a "Change of Control" (as defined below)

Company is not the survivor and the Company's stockholders prior to the merger
control less than fifty percent of the voting stock of the surviving entity,
(iii) a sale by the Company's stockholders to an acquiror or acquirors acting
in concert of more than a majority of the then outstanding stock of the

Agreement, Mr. Scheps was granted a warrant to purchase 100,000 shares of the
Company common stock at an exercise price of $1.00 per share.  This warrant is
exrcisable solely in the event of a Change of Control.

he serves as Executive Vice President of the Company through December 31, 1999
at an annual base salary of $99,600.  There are no benefits payable to Dr.
Cohen upon termination of the agreement.

                  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, 1998
and 1997, and the related statements of income, shareholders'
equity and cash flows for each of the three years in the period
ended December 31, 1998.  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, 1998 and 1997,
and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

                       NOTES TO FINANCIAL STATEMENTS

                             DECEMBER 31, 1998




(1)   The Company:

      CAS Medical Systems, Inc. (the "Company")operates in one business
      segment and 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 1998, 1997 and 1996, the
      Company had sales to one customer which in the aggregate accounted for
      approximately 13% of sales, in each of the three years reported, and
      had export sales principally to Europe, including licensing fee
      revenues, of $2,254,619, $2,251,702, and $2,371,007, 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.  Property 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 and the
      building which has a life of 20 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.

                                    F-8

      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, Basic Earnings Per Share
      is calculated by dividing net income by the weighted average nunmber of
      shares of common stock outstanding during the year.  No dilution for
      any potentially dilutive securities is included.  Diluted Earnings Per
      Share assumes the conversion of all potentially dilutive securities
      using the treasury stock method.  The Company adopted SFAS No. 128 in
      1997 and, as required, applied it retroactively to the 1996 financial
      statements.

      As of December 31, 1998, the Company had 650,100 options and 1,295,000
      warrants to purchase shares of common stock outstanding.

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

                                              1998        1997        1996

      Net income                          $  816,252     665,043     905,714

      Add:  dilutive warrants and options    510,412     650,212     912,073
                                           ---------   ---------   ---------

        dilutive securities outstanding    9,839,689   9,979,489  10,228,275

                                           ---------  ----------   ---------

                                           ---------  ----------   ---------

      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.

(4)   Debt:

      At December 31, 1998, the Company's line of credit arrangement allowed
      for maximum borrowings of $1,000,000, all of which was available.  The
      line of credit arrangement expires on August 1, 1999 and bears interest
      at the prime rate (8.5% at December 31, 1999) plus 1%.  During 1997 and
      1996, the maximum month end borrowings outstanding under this line were
      $100,000, the weighted average borrowings were $8,333, and the weighted
      average interest rates on amounts outstanding were 9.5%.  There were no
      borrowings against the line of credit during 1998.  The bank has a
      first security interest in all assets of the Company and requires a
      compensating balance equal to 10% of the line of credit ($100,000 at
      December 31, 1998).

(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 grants a
      nonexclusive license to use the Company's blood pressure technology for
      a specific application.  As part of this agreement, the Company will
      receive $1,500,000 plus royalties through the year 2000, of which
      $1,100,000 has been received through December 31, 1998.  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 Company's Series C cumulative preferred stock were
      entitled to a cumulative dividend, payable quarterly, at the annual
      rate of $10 per share.  On July 17, 1996, the final 3,000 shares of the
      Company's Series C preferred stock were redeemed at $100 per share plus
      accrued dividends.

(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.

      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 1998, 1997
      and 1996 net income and earnings per share would have been reduced to
      the following pro forma amounts:

                                                  1998      1997     1996

   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 1998 and 1996:  risk-free interest rates of
   5.08% and 6.06%; expected lives of 10 years; expected volatility of 75%
   and 74%, respectively.

(8)  Life Insurance-

   During 1998, 1997 and 1996, the Company paid life insurance premiums of
   approximately $23,000, $20,000 and $17,000, 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.

(9)  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 1998, 1997 and 1996
   contributions by the Company were $48,553, $32,260 and $31,512,
   respectively.

   The Company does not provide other post-retirement or other
   post-employment benefits.

 (10)  Income Taxes:

   The Company follows Statement of Financial Accounting Standards No. 109,
   "Accounting for Income Taxes ("SFAS No. 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 No. 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.

   The components of the Company's deferred tax assets at December 31, 1998
   and 1997 are as follows:

                                            1998            1997

</TABLE>

   The effective tax rate differs for the federal statutory rate of 34% in
   ech year principally due to state income taxes.

(11)  Other Income

   During 1998, the Company and a third party distributor terminated a sales
   contract.  The Company received a $725,000 settlement from the third party
   and has recorded this amount in other income due to its non-recurring
   nature.

(12)  Commitments and Contingencies:

   Employment Agreements-

   The Company is committed under employment agreements with two officers for
   payments aggregating approximately $281,000 which expire on December 31,
   1999 and August 31, 2000.

(13)  Subsequent Event

   In February 1999, the Company obtained a nineteen year, 7.25% fixed rate
   $1,310,000 mortgage from a bank.  The mortgage is secured by a first
   mortgage lien on the Company's property consisting of a 4.627 acre parcel
   of land and the 24,000 square foot industrial building and associated
   improvements on it.  The interest rate will be subject to a rate
   adjustment ten years from the anniversary date.  The interest rate will be
   adjusted to 2.50% over the weekly average yield on United States Treasury
   Securities in affect 45 days prior to the adjustment date.  Monthly
   installment payments of $11,000, which includes interest, are required.

(3)  Debt

At March 31, 1999, the Company had a line of credit with a Connecticut
bank totaling $1,000,000.  Borrowings under the line of credit bear
interest at the prime rate plus 1.0%.  At March 31, 1999, 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 10% of the line of credit.

(4) License Agreement:

On July 27, 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 special 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 $1,100,000 in license fees has been received
through March 31, 1999.  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.

(5) Long-Term Debt

During November 1998, the Company relocated to a 24,000 square foot
office, laboratory and manufacturing facility owned by the Company in
Branford, Connecticut.  Total cost of this new facility was
approximately $1,933,000.  The Company is the sole tenant of this new
facility.

During January 1999, the Company obtained a nineteen year, 7.25% fixed
rate $1,310,000 mortgage from a local bank.  The mortgage is secured by
a first mortgage lien on the Company property consisting of 4.6 acres
of land and the 24,000 square foot industrial building.  The monthly
payments, including interest, are approximately $11,000.

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

    Liquidity and Capital Resources

    As of March 31, 1999, the Company's cash and cash equivalents
totaled $2,002,387 compared to $1,442,342 at December 31, 1998, and the
Company's working capital totaled $3,345,089 on March 31, 1999,
compared to $1,974,600 on December 31, 1998.  The Company's increased
cash position is primarily due to the $1,310,000 mortgage obtained
during January, 1999.


<PAGE>
                Notes to Financial Statements - (Continued)

     At March 31, 1999, the Company had a line of credit with a Connecticut
bank totaling $1,000,000.  Borrowings under the line of credit bears interest
at the prime rate plus 1.0%.  At March 31, 1999, 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
$101,000 ($.01 per common share on a diluted basis), compared to $182,000
($.02 per common share on a diluted basis), reported for the first quarter of
1998.  The 1999 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, 1999
were approximately $1,797,000 as compared to approximately $1,755,000 for the
comparable period in the prior year.  The small increase in 1999 is due
primarily by softness in sales of certain disposable products whereas
diagnostic equipment reflected a significant increase of 54 percent for the
same period of 1998.

    Total cost of product sales as a percent of net product sales was 45.1
percent for 1999 compared to 39.7 percent for 1998.  The unfavorable impact is
due primarily to product mix during the first quarter of 1999.

     Selling, general administrative, research and development expenses were
approximately $861,000 for the first quarter of 1999, compared to
approximately $807,000 for the same period of 1998, an increase of $54,000 or
7 percent.  The overall increase in 1999 is the result of additional personnel
for the selling and marketing departments.

     The provision for income taxes of $59,000 and $120,000 for the three
month period ended March 31, 1999 and 1998, respectively, represents state and
federal income taxes.

     These factors resulted in net income of approximately $101,000 for the
first quarter of 1999, as compared to net income of approximately $182,000 for
the comparable period in the prior year.

Note 4.  Debt:

At June 30, 1999, the Company had a line of credit with a Connecticut
bank totalling $1,000,000.  Borrowings under the line of credit bear
interest at the prime rate plus 1.0%.  At June 30, 1999 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 10% of the line of credit.

Note 5.  License Agreement:

On July 27, 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 $1,100,000 in license
fees has been received through June 30, 1999.  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.

Note 6.  Long-Term Debt

During November 1998, the Company relocated to a 24,000 square foot
office, laboratory and manufacturing facility owned by the Company in
Branford, Connecticut.  Total cost of this new facility was approximately
$1,933,000.  The Company is the sole tenant of this new facility.

On January 19, 1999, the Company obtained a nineteen year, 7.25% fixed
rate $1,310,000 mortgage from a local bank.  The mortgage is secured by a
first mortgage lien on the Company property consisting of 4.6 acres of
land and the 24,000 square foot industrial building.  The monthly
payments, including interest, are approximately $11,000.


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

    Liquidity and Capital Resources

    At June 30, 1999, the Company's cash and cash equivalents totaled
$2,040,887 compared to $1,442,342 at December 31, 1998.  The Company's
working capital totaled $3,496,782 on June 30, 1999, compared to
$1,974,600 on December 31, 1998.  The Company's increased cash position is
primarily due to the $1,310,000 mortgage obtained during January, 1999.

               Notes to Financial Statements (continued)

    At June 30, 1999, the Company had a line of credit with a Connecticut
bank totaling $1,000,000.  Borrowings under the line bear interest at the
prime rate plus 1.0%.  At June 30, 1999, there were no borrowings
outstanding 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, 1999 was
approximately $220,000 ($0.02 per share assuming dilution), compared to
approximately $376,000 ($0.04 per share assuming dilution), for the same
period of 1998.  Net income for the second quarter of the current year was
approximately $119,000 ($.01 per share assuming dilution), compared to
approximately $193,000  ($0.02 per share assuming dilution), reported for
the second quarter of 1998.  The 1999 earnings performance was impacted by
the investments incurred to increase personnel in the selling and
marketing departments.

     The Company's revenues for the three month period ended June 30,
1999 were approximately $2,044,000 as compared to approximately $1,872,000
for the comparable period in the prior year.  Revenues for the six month
period ended June 30, 1999 reached approximately $3,840,000, compared to
approximately $3,627,000 of the comparable period of 1998.  Revenues for
1999 reflect a significant increase of approximately $436,000 for
non-invasive blood pressure equipment, whereas Klear-Trace and disposable
products decreased by approximately $223,000.

     Cost of product sales as a percentage of net product sales was 44.9
percent for 1999 compared to 40.5 percent for 1998.  The unfavorable
impact is due primarily to product mix.

     Selling, general and administrative expenses were approximately
$1,542,000 for the six month period ended June 30, 1999 as compared to
approximately $1,383,000 for the same period of 1998, an increase of
$159,000 or 11 percent.  This increase in expenses for 1999 is due
primarily to additional personnel both in the selling and marketing
departments.

     The provision for income taxes of $141,000 and $250,000 for the six
month period ended June 30, 1999 and 1998, respectively, represents state
and federal income taxes.

     These factors and licensing revenues resulted in net income of
approximately $220,000 for the period ended June 30, 1999, as compared to
net income of approximately $376,000 for the comparable period in the
prior year.

           Notes to Financial Statements - September 30, 1999

Note 4.  Debt:

At September 30, 1999, the Company had a line of credit with a
Connecticut bank totalling $1,000,000.  Borrowings under the line of
credit bear interest at the prime rate plus .50%.  At September 30, 1999
the amount outstanding under this line was $400,000.  The bank has a first
security interest in all assets of the Company and requires a compensating
balance equal to 10% of the line of credit.

Note 5.  License Agreement:

On July 27, 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 $1,100,000 in license
fees has been received through September 30, 1999.  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.

Note 6.  Long-Term Debt

During November 1998, the Company relocated to a 24,000 square foot
office, laboratory and manufacturing facility owned by the Company in
Branford, Connecticut.  Total cost of this new facility was approximately
$1,933,000.  The Company is the sole tenant of this new facility.

On January 19, 1999, the Company obtained a nineteen year, 7.25% fixed
rate $1,310,000 mortgage from a local bank.  The mortgage is secured by a
first mortgage lien on the Company property consisting of 4.6 acres of
land and the 24,000 square foot industrial building.  The monthly
payments, including interest, are approximately $11,000.


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

    Liquidity and Capital Resources

    At September 30, 1999, the Company's cash and cash equivalents
totaled $2,408,372 compared to $1,442,342 at December 31, 1998.  The
Company's working capital totaled $3,606,073 on September 30, 1999,
compared to $1,974,600 on December 31, 1998.  The Company's increased cash
position is primarily due to the $1,310,000 mortgage obtained during
January, 1999.

    At September 30, 1999, the Company had a line of credit with a
Connecticut bank totaling $1,000,000.  Borrowings under the line bear
interest at the prime rate plus .50%.  At September 30, 1999, the amount
outstanding under this line was $400,000.

     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 nine month period ended September 30, 1999 was
approximately $320,000 ($0.03 per share assuming dilution), compared to
approximately $513,000 ($0.05 per share assuming dilution), for the same
period of 1998.  Net income for the third quarter of the current year was
approximately $99,000 ($.01 per share assuming dilution), compared to
approximately $138,000 ($0.01 per share assuming dilution), reported for
the third quarter of 1998.  The 1999 earnings performance was impacted by
the investments incurred to increase personnel in the selling and
marketing departments.

     The Company's revenues for the third quarter ended September 30,
1999 were approximately $1,934,000 as compared to approximately $1,724,000
for the comparable period in the prior year.  Revenues for the nine month
period ended September 30, 1999 reached approximately $5,628,000, compared
to approximately $5,211,000 reported for the same period of 1998.
Revenues for 1999 reflect a significant increase of 43 percent for
diagnostic equipment whereas disposable products decreased slightly from
the prior year.

     Total cost of product sales as a percentage of net product sales was
44.3 percent for 1999 compared to 41.8 percent for 1998.  The unfavorable
impact is due primarily to product mix.

     Selling, general and administrative expenses were approximately
$2,378,000 for the nine month period ended September 30, 1999 as compared
to approximately $2,072,000 for the same period of 1998, an increase of
$306,000 or 15 percent.  This increase in expenses for 1999 is due
primarily to additional personnel, both domestic and international.

     The provision for income taxes of $204,000 and $343,000 for the nine
month period ended September 30, 1999 and 1998, respectively, represents
state and federal income taxes.

     These factors and licensing revenues resulted in net income of
approximately $320,000 for the period ended September 30, 1999, as
compared to net income of approximately $513,000 for the comparable period
in the prior year.
