                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and Consolidated Financial Statements and Notes thereto appearing
elsewhere in this Prospectus, including information under "Risk Factors."
 
                                  THE COMPANY
 
     Quest Medical, Inc. ("Quest" or the "Company") designs, develops,
manufactures and markets a variety of healthcare products used primarily in
cardiovascular surgery, interventional pain management and intravenous fluid
delivery applications. The Company operates several stable and profitable
product lines, including cardiovascular products (such as pressure control
valves, filters and surgical retracting tapes), specialized intravenous fluid
delivery tubing sets and accessories, and pressure monitoring kits used
primarily in labor and delivery. The Company has levered these product lines,
its existing corporate infrastructure and its core competencies in medical
device manufacturing, engineering and regulatory affairs to expand into new
markets as evidenced by the internally funded development of the Quest MPS brand
of myocardial protection system, an innovative and sophisticated system designed
to manage the delivery of solutions to the heart during open-heart surgery. In
addition, the Company recently entered the interventional pain management market
by acquiring Neuromed, Inc. ("Neuromed"), which designs, develops, manufactures
and markets a line of electronic spinal cord stimulation ("SCS") devices used to
manage chronic severe pain.
 
     In 1991, Quest acquired two companies that manufactured and marketed
various cardiovascular products, significantly enhancing the Company's presence
in the cardiovascular products marketplace. In 1992, Quest identified a real and
immediate need in this marketplace for an automated and integrated myocardial
protection system that would be versatile, easy to use, efficient to monitor and
cost-effective. Myocardial protection is the process of arresting and caring for
the heart during open-heart surgery. The Quest MPS system is designed to
integrate key functions relating to the delivery of solutions to the heart such
as varying the rate and ratio of oxygenated blood, crystalloid, potassium and
other additives, and controlling temperature, pressure and other variables to
allow simpler, more flexible and cost-effective management of this process. The
MPS system employs advanced pump, temperature control and microprocessor
technologies and includes a line of captive and non-captive disposable products.
The Company filed a 510(k) pre-market notification for its MPS system with the
United States Food and Drug Administration ("FDA") in August 1995.
 
     In its continuing effort to expand into potentially high growth niche
markets in the medical device industry, the Company acquired Neuromed in March
1995 (the "Neuromed Acquisition"). SCS is gaining increased acceptance as a
viable, efficacious and cost-effective treatment alternative to repeat back
surgeries for relieving chronic severe back pain. The Company believes that its
recently introduced CompuStim products, which are powered by radio frequency
transmitters external to the body, are the technological leaders in the field.
The Company is currently test marketing PainDoc, a pen-based computer system
that works in tandem with the Company's CompuStim devices to assist physicians
and their patients in optimizing the performance of the Company's SCS devices
both pre-and post-operatively.
 
     Since its founding in 1979, the Company has developed, manufactured and
marketed specialized intravenous fluid delivery tubing sets and accessories sold
primarily to major hospitals in the United States. Over the last several years,
the revenues generated by this product line, a substantial component of the
Company's historical base business, have significantly aided the funding of the
Company's research and development efforts. The Company manufactures and markets
over 70 distinct models of specialized intravenous fluid delivery tubing sets.
 
     The Company's business strategy emphasizes the development and
commercialization of new products in niche markets and the enhancement of
existing products, particularly in the myocardial protection and interventional
pain management markets. The Company operates an ISO 9001 certified
manufacturing facility in Allen, Texas, and markets its products through direct
sales and distribution arrangements with independent distributors. Quest intends
to continue pursuing its strategy through internal product development and
acquisitions.

(1) Does not include 1,168,548 shares of Common Stock issuable upon the exercise
    of outstanding stock options at a weighted average exercise price of $4.15
    per share. See "Management -- Benefit Plans and Other Arrangements."
(2) Assumes the acquisition of Neuromed as of January 1, 1994. See Pro Forma
    Condensed Consolidated Statements of Operations and the Notes thereto.
(3) Includes results of Neuromed from April 1, 1995.
(4) Non-recurring charge in 1992 relates to the write-off of assets of a
    discontinued business, and for the six months ended June 30, 1995, relates
    to purchased in-process research and development incurred in connection with
    the Neuromed Acquisition. See Note 2 of the Notes to the Quest Consolidated
    Financial Statements.
(5) Includes an increase in net income of $0.03 per share relating to the
    cumulative effect of a change in accounting principle. See Note 1(m) of the
    Notes to the Quest Consolidated Financial Statements.
(6) If the proceeds of this Offering had been applied to reduce bank debt as of
    January 1, 1994 in the manner specified under "Use of Proceeds," then pro
    forma loss per share before extraordinary charge for the year ended December
    31, 1994 would have been $(0.01) and pro forma net earnings per share for
    the six months ended June 30, 1995 would have been $0.11. An extraordinary
    charge resulting from the write-off of capitalized debt issuance costs
    associated with the assumed January 1, 1994 repayment of bank debt would
    have reduced 1994 pro forma net earnings by $0.03 per share.
(7) Adjusted to reflect the accrual of $1.5 million payable in January 1996 and
    the issuance of 200,000 shares of Common Stock concurrently with the closing
    of the Offering as contingent "earn-out" consideration relating to the
    Neuromed Acquisition. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations -- Overview" and "Certain Transactions."
(8) Adjusted to reflect the sale of 1,316,667 shares of Common Stock offered by
    the Company at the public offering price of $10.00 per share and the
    application of the estimated net proceeds therefrom. See "Use of Proceeds."

    Unless otherwise indicated, all information in this Prospectus, including
financial information, share and per share data, (i) reflects a 3% stock
dividend, paid on May 23, 1994 to holders of record on May 6, 1994, and (ii)
assumes no exercise of the Underwriters' over-allotment option. Unless the
context otherwise requires, "Quest" or the "Company" refers to Quest Medical,
Inc. and its subsidiaries, including Neuromed, Inc.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered carefully by potential investors in evaluating an
investment in the shares of Common Stock offered hereby.
 
PRODUCT DEVELOPMENT AND MARKET ACCEPTANCE
 
     The Company's business strategy emphasizes the development and
commercialization of new products in niche markets and the enhancement of
existing products, particularly in the myocardial protection and interventional
pain management markets. There can be no assurance that the Company will be able
to continue to develop new products, enhance existing products, obtain required
regulatory approvals, manufacture these new products in a commercially viable
manner or gain satisfactory market acceptance for such products.
 
     In particular, the Company's future growth depends in part on market
acceptance of the MPS system and family of related products and increased market
acceptance of the Company's spinal cord stimulation products. The Company has
committed substantial resources to the development of the MPS system and related
products. Delays in commencing shipment of the MPS system and related products,
or in developing complementary new products, could have an adverse effect on the
Company's growth prospects. There can be no assurance that such products, if
introduced, will gain market acceptance. The Company also recently acquired its
spinal cord stimulation device business. Although the Company believes that this
business will grow in the future, there can be no assurance that these products
will continue to gain increased market acceptance. See "Business -- Research and
Development" and "Business -- Competition."
 
INTEGRATION OF NEUROMED
 
     The Company recently completed the acquisition of Neuromed. Successful
integration of an acquired company into existing operations can be difficult and
costly. Quest has begun to integrate into the Company certain of Neuromed's
operations, research and development, sales and marketing, and administrative
functions. The desired benefits of the Neuromed Acquisition will not be achieved
unless the separate operations of the Company and Neuromed are successfully
combined in an orderly and timely manner. The transition process will divert
substantial management attention from the Company's other operations and
activities. Any limitations or difficulties encountered in the transition
process could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Overview."
 
GOVERNMENT REGULATION; UNCERTAINTY OF OBTAINING REGULATORY CLEARANCE
 
     The research and development, manufacture, sale and distribution of medical
devices is subject to extensive regulation by various public agencies,
principally the FDA and corresponding state, local and foreign agencies. The
regulatory process is lengthy, expensive and uncertain. Prior to commercial sale
in the United States, most medical devices must be cleared or approved by the
FDA. Current FDA enforcement policy strictly prohibits the promotion of medical
devices for uses other than those for which the product has been approved or
cleared. Product approvals and clearances can be withdrawn for failure to comply
with regulatory requirements or the occurrence of unforeseen problems following
initial marketing.
 
     In August 1995, the Company filed an application for clearance of a
pre-market notification of its intent to market the MPS system and certain
related products under Section 510(k) of the Federal Food, Drug and Cosmetic Act
("510(k)"). Although the Company believes that the 510(k) procedure is the
appropriate basis upon which to seek FDA clearance or approval, there can be no
assurance that the FDA will accept this view and consider the Company's 510(k)
application. If it is not accepted under the 510(k) procedure, the Company will
have to pursue a pre-market approval ("PMA") for the MPS system. This process
would be far more costly and time consuming than 510(k) clearance. Even if
 
                                        5
<PAGE>   6
 
the FDA considers the MPS system under the 510(k) procedure, there can be no
assurance that the FDA will approve the Company's application. See
"Business -- Government Regulation."
 
     Significant unforeseen delays in the 510(k) review process or, if
necessary, the PMA approval process could occur as a result of the FDA's
determination that any required clinical data is insufficient to support the
safety and efficacy of these devices for their intended uses, the FDA's failure
to schedule advisory review panels, or changes in the FDA's review guidelines,
procedures, regulations or administrative interpretations. Delays in obtaining
regulatory clearances or approvals, or the failure to obtain required clearances
or approvals, in the United States or other countries, could adversely affect or
prevent the marketing of these products, limit the Company's ability to generate
revenues from these devices and give the Company's competitors a competitive
advantage. There can be no assurance that the Company will be able to obtain
necessary government approvals on a timely basis, if at all.
 
     The Company also must adhere to applicable regulations governing good
manufacturing practices, including testing, control, manufacturing, labeling and
documentation requirements. If violations of the applicable regulations are
noted during inspections of the Company's manufacturing facilities by the FDA or
comparable agencies in other countries, the Company may be required or may elect
to cease manufacturing until the violation is corrected or to recall products
that were manufactured under improper conditions, either of which would have a
material adverse effect on the Company's continued marketing of its products and
on the Company's business, financial condition and results of operations.
 
     In 1991, prior to its acquisition by the Company, Neuromed commenced
clinical trials of a fully implantable SCS device in the United States and
Europe. In late 1993, the FDA cancelled the Investigational Device Exemption
("IDE") relating to this product and rescinded Neuromed's export authority for
this product due to alleged violations by Neuromed, under its prior management,
of applicable rules and regulations, including good manufacturing practices. The
clinical trials were discontinued and the product was withdrawn from the market.
During this period, Neuromed also encountered regulatory difficulties in the
United Kingdom due to alleged noncompliance with applicable rules and
regulations. Quest is engaged in a process intended to restore good relations
with regulatory authorities in the United Kingdom. There can be no assurances
that the Company will not encounter similar difficulties in the future.
 
     A portion of the Company's revenues are dependent upon sales of its
products outside the United States through independent distributors.
International regulatory bodies have established varying regulations governing
product standards, packaging requirements, labeling requirements, import
restrictions, tariff regulations, duties and tax requirements. The Company's
inability or failure to comply with these regulations or the imposition of new
regulations could restrict such distributors' ability to sell the Company's
products internationally and thereby adversely affect the Company's business,
financial condition and results of operations. See "Business -- Government
Regulation."
 
INTENSE COMPETITION, CONTINUAL TECHNOLOGICAL CHANGE AND NEW SURGICAL TECHNIQUES
 
     The medical device market is highly competitive. The Company currently
competes with many companies in the development and marketing of cardiovascular
products, specialized intravenous fluid delivery tubing sets, pressure
monitoring kits and related medical devices. The Company expects to compete with
at least two major medical device companies in the myocardial protection market,
and competes directly with Medtronic, Inc., one of the largest medical device
manufacturers, in the SCS product market. Many of the Company's competitors have
access to greater capital, research and development, marketing, distribution and
other resources than the Company. Furthermore, the medical device market is
characterized by extensive research efforts and rapid product development and
technological change. The Company's present or future products could be rendered
obsolete and noncompetitive by technological advances by the Company's present
or future competitors. The Company's future success will depend upon its ability
to remain competitive with other developers of medical devices. See
"Business -- Competition."
 
                                        6
<PAGE>   7
 
     In addition, innovations in surgical techniques or medical practices could
have the effect of reducing or eliminating market demand for one or more of the
Company's products. For example, some cardiovascular surgeons and medical device
companies are developing techniques, procedures and devices for performing
coronary artery bypass surgery without stopping the heart, both through open-
heart surgery and minimally invasive procedures, thereby eliminating the need
for myocardial protection in these cases and potentially reducing the market for
Quest's MPS system. While these techniques, procedures and devices have not to
date attained widespread use, there can be no assurance that they will not gain
broader market acceptance. See "Business -- Competition."
 
DEPENDENCE ON PATENTS AND PROPRIETARY RIGHTS
 
     The Company owns nineteen United States patents relating to products that
the Company currently sells or develops. One such patent will expire in February
1996 and one will expire in January 1997. In addition, the Company currently has
three United States patent applications pending, including applications relating
to the MPS system and related products. Successful litigation against the
Company regarding its patents or infringement by the Company of the patent
rights of others could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, there can be no
assurance that pending patent applications will result in issued patents, that
competitors will not challenge or circumvent patents issued to the Company, that
courts will not find the Company's patents invalid, or that the Company's
patents are sufficiently broad to protect the Company's technology or to provide
the Company with a competitive advantage. The Company also relies on trade
secrets and proprietary technology that it seeks to protect, in part, through
confidentiality agreements with employees, consultants and other parties. There
can be no assurance that these parties will not breach these agreements, that
the Company will have adequate remedies for any breach, or that the Company's
trade secrets will not otherwise become known to or independently developed by
competitors.
 
     There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry. Although the
Company is not currently involved in such litigation, litigation may be
necessary in the future to enforce the Company's patent rights, to protect its
trade secrets or know-how, to defend the Company against claimed infringement of
the rights of others and to determine the scope and validity of the proprietary
rights of others. Any such litigation could result in substantial cost to, and
diversion of effort by, the Company. Adverse determinations in any such
litigation could subject the Company to significant liabilities to third
parties, require the Company to seek licenses from third parties and prevent the
Company from manufacturing, selling or using certain of its products, any of
which could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Patents, Trademarks and
Proprietary Rights."
 
COST PRESSURES ON MEDICAL TECHNOLOGY; THIRD PARTY REIMBURSEMENT
 
     The Company believes that the overall escalating cost of medical products
and services has led and will continue to lead to increased pressures on the
healthcare industry to reduce the cost of certain products and services,
including the Company's products. The Company's products are purchased by
hospitals and other users, which bill various third party payors, such as
governmental health programs, private insurance plans, managed care
organizations and other similar programs, for the healthcare products and
services provided to their patients. Third party payors are increasingly
challenging the prices charged for medical products and services and may deny
reimbursement if they determine that a device was not used in accordance with
cost-effective treatment methods as determined by the payor, was experimental or
was used for an unapproved application. Although Medicare, Medicaid and many
health maintenance organizations ("HMOs") generally reimburse for SCS devices
and procedures, especially after repeat back surgeries have failed to relieve
the chronic pain, certain payors refuse to reimburse for SCS devices and others,
including the Veterans Administration, restrict reimbursement. There can be no
assurance that third party payors will continue to reimburse for the Company's
 
                                        7
<PAGE>   8
 
products or that their reimbursement levels will not adversely affect the
profitability of the Company's products. See "Business -- Third Party
Reimbursement and Cost Containment."
 
POTENTIAL PRODUCT LIABILITY AND RECALL; POSSIBLE INSURANCE LIMITATIONS
 
     The testing, manufacturing, marketing and sale of medical devices entail
substantial risks of liability claims or product recalls. The Company's products
are used in cardiovascular applications, spinal cord implant procedures and
intensive care settings in which there is a high risk of serious injury and
death. As a result, the Company faces a risk of exposure to product liability
claims and product recalls if the use of its products or future products are
alleged to have resulted in injury. Such risks may exist with respect to
products that have received, or may receive, regulatory clearance for commercial
sale. In 1993, the FDA cancelled the IDE for a fully implantable SCS device, and
rescinded Neuromed's export authority for this product. See "-- Government
Regulation; Uncertainty of Obtaining Regulatory Clearance" and
"Business -- Government Regulation."
 
     The Company is currently a party to certain product liability claims
relating to SCS devices sold by Neuromed prior to its acquisition by the Company
in March 1995, including one claim regarding the fully implantable SCS device.
Product liability insurers have assumed responsibility for defending the Company
against these claims, subject to reservation of rights in certain cases.
Although the Company is also entitled to contractual indemnification from
Neuromed's former owner with respect to any losses exceeding its product
liability insurance coverage, there can be no assurance that the Company will
not incur significant monetary liability to the claimants if such insurance or
indemnification is unavailable or inadequate for any reason or that the
Company's SCS business or new SCS product lines will not be adversely affected
by these product liability claims. See "Business -- Legal Proceedings."
 
     While the Company seeks to maintain appropriate levels of product liability
insurance with coverage that the Company believes is comparable to that
maintained by companies similar in size and serving similar markets, there can
be no assurance that the Company will avoid significant future product liability
claims and attendant adverse publicity. Furthermore, there can be no assurance
that the Company's product liability insurance will be adequate or that such
insurance coverage will remain available at acceptable costs or at all. A
successful claim brought against the Company for which coverage is denied or in
excess of its insurance coverage could have a material adverse effect on the
Company's business, financial condition and results of operations. Additionally,
adverse product liability actions could adversely affect the Company's ability
to obtain and maintain regulatory clearance for its products or its ability to
attract and retain customers for its products.
 
DEPENDENCE ON DISTRIBUTOR SALES
 
     Sales to distributors constitute a significant portion of the Company's
business. There can be no assurance that the Company will be able to maintain
its relationships with these distributors, or, in the event of termination of
any of these relationships, that a new distributor will be found. The loss of a
significant distributor could have a material adverse effect on the Company's
business, financial condition and results of operations if a new distributor or
other suitable sales organization in the relevant geographic market could not be
found on a timely basis or at all. See "Business -- Sales and Marketing."
 
RELIANCE ON MAJOR CUSTOMER
 
     The Company has derived $3.4 million, $3.1 million, $2.7 million and $1.5
million, or 25%, 23%, 19% and 14%, of its net revenue for the years ended
December 31, 1992, 1993 and 1994 and the six months ended June 30, 1995,
respectively, from the University of Texas System Cancer Center (M.D. Anderson
Hospital). The loss of this customer could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Sales and Marketing."
 
                                        8
<PAGE>   9
 
INTERRUPTION IN SOURCES OF SUPPLY
 
     The Company currently purchases, and will continue to purchase, raw
materials and components for its products from outside vendors. Certain of the
components used in the Company's products are purchased from single sources.
Although the Company has qualified, or is in the process of investigating,
alternate sources of supply for key components, any significant interruption in
supply of these or other components could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Manufacturing."
 
POSSIBLE VOLATILITY OF SHARE PRICE
 
     Market prices for securities of medical device companies are highly
volatile, and the trading price of the Company's Common Stock could be subject
to significant fluctuations in response to quarterly variations in operating
results, announcements of technological innovations by the Company or its
competitors, government regulation and other events or factors. In addition,
market prices of securities of medical device companies, including the Company,
have from time to time experienced extreme price and volume fluctuations which
may be unrelated to the operating performance of particular companies. These
broad market fluctuations could have a material adverse effect on the market
price of the Company's Common Stock.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's success is dependent in large part on the ability of the
Company to attract and retain key management, research and development, sales
and marketing and operational personnel. Competition for such personnel is
intense and the inability to attract and retain additional key personnel, or the
loss of one or more current key employees could have a material adverse effect
on the Company's business, financial condition and results of operations. In
particular, the Company's success will depend on its ability to retain the
services of its executive officers and senior management. In addition, the
Company will have an ongoing need to expand its management personnel and support
staff. None of the executive officers of the Company has an employment agreement
with the Company, and the Company does not maintain life insurance on such
persons. See "Management."
 
SHAREHOLDERS' RIGHTS PLAN; POTENTIAL ANTI-TAKEOVER EFFECT
 
     The Company's Shareholders' Rights Plan contains provisions which may have
the effect of delaying, deferring or preventing a change in control of the
Company. The Shareholders' Rights Plan grants the holders of rights (other than
rights held by a holder of 20% or more of the Common Stock) the right to buy a
number of shares of Common Stock having a market value equal to two times the
applicable exercise price under certain circumstances, including a person's
acquisition of 20% or more of the outstanding Common Stock. See "Description of
Capital Stock -- Shareholders' Rights Plan."

<PAGE>   10
 
                                  THE COMPANY
 
     The Company was founded in 1979 by current President and Chief Executive
Officer, Thomas C. Thompson, and director John A. Gula. The Company completed an
initial public offering of its Common Stock in 1981 and introduced a line of
electronic intravenous pumps and associated disposables beginning in late 1983.
The Company sold the intravenous pump line in 1987 due to competitive structural
changes in the market. The Company retained a stable and profitable base
business of fluid delivery and other products following the sale and made the
strategic decision to expand into attractive markets in which the Company could
leverage off its base business, corporate infrastructure and core competencies
in medical device manufacturing, engineering and regulatory affairs. In 1991,
Quest acquired two companies that manufactured and marketed various
cardiovascular products, significantly enhancing the Company's presence in the
cardiovascular products marketplace. In 1992, Quest acquired the "ACTester"
product line, consisting of instrumentation and associated disposables used to
measure the activated clotting time of blood, and commenced the research and
development of the MPS system. In March 1995, the Company acquired Neuromed and
its SCS neurostimulation product line, and in August 1995, the Company filed a
510(k) with the FDA for its MPS system and related disposable products.
 
     Quest is a Texas corporation. Its principal executive offices are located
at One Allentown Parkway, Allen, Texas 75002 and its telephone number is
(214) 390-9800.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,316,667 shares of
Common Stock to be sold by the Company in the Offering are estimated to be $11.9
million ($15.2 million if the Underwriters' over-allotment option is exercised
in full), after deducting underwriting discounts and commissions and estimated
offering expenses payable by the Company. The Company intends to use the net
proceeds from the Offering to repay $11.9 million of the $13.9 million of senior
term bank indebtedness currently outstanding, which was incurred in March 1995
in connection with the Neuromed Acquisition. If the Underwriters' over-allotment
option is exercised, the Company intends to repay as much of its remaining
senior term bank indebtedness and as much of its working capital line of credit
as possible ($4.6 million is currently outstanding). The Company will not
receive any of the proceeds from the sale of shares of Common Stock by the
Selling Shareholders.
 
     The senior term debt amortizes $1.95 million per year for the first and
second years, $3.25 million per year for the third and fourth years, and $2.6
million for the fifth year, with a $2.0 million balloon payment due at final
maturity in March 2000. The working capital line matures on May 31, 1997.
Principal installments and interest on the senior term debt and interest on the
working capital line are payable monthly. Currently, the loan bears interest at
prime plus 50 basis points or, at the Company's option, LIBOR plus 200 basis
points, and interest rates can be locked in at the Company's option for varying
periods of time. These interest rates can also be reduced based on the Company
achieving certain ratios of senior bank debt to earnings before interest, taxes,
depreciation and amortization. As of November 6, 1995, the rate of interest on
the senior term loan was 9.25% and the rate of interest on the working capital
indebtedness was 7.87%.

                          PRICE RANGE OF COMMON STOCK
 
     The Company's Common Stock is quoted on the Nasdaq National Market under
the symbol "QMED." On November 9, 1995, the last reported sale price for the
Company's Common Stock on the Nasdaq National Market was $10.63 per share. On
November 6, 1995 there were approximately 850 holders of record of the Company's
Common Stock. The following table sets forth the quarterly high and low closing
sales prices for the Company's Common Stock. These prices do not include
adjustments for retail mark-ups, mark-downs or commissions.

                                DIVIDEND POLICY
 
     To date, the Company has not declared or paid any cash dividends on its
Common Stock, and the present policy of the Board of Directors is to retain any
earnings to provide for the Company's growth. Any future determination to pay
dividends will be at the discretion of the Board of Directors, and dependent
upon the Company's financial condition, results of operations, capital
requirements and such other factors as the Board of Directors deems relevant. In
addition, the Company's current credit arrangement with NationsBank of Texas,
N.A. ("NationsBank") currently limits the payment of dividends to 25% of net
income (as defined in the credit agreement). The Company intends to use the net
proceeds from the Offering to repay this indebtedness, and thus such
restrictions are expected to lapse upon such repayment. See "Use of Proceeds."
The Company has received a commitment letter from NationsBank that provides for
an amendment of the working capital line of credit and the addition of an
acquisition line of credit. Management expects to negotiate a dividend
limitation that would apply if the acquisition line of credit is utilized. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     The Company has paid one stock dividend on its Common Stock. During April
1994, the Board of Directors approved a 3% stock dividend distributed on May 23,
1994 to shareholders of record as of May 6, 1994. In connection with the
dividend, the Company issued 152,829 shares of Common Stock from its treasury.
 
     The Board of Directors on various occasions, beginning in October 1987 and
as recently as August 1993, approved stock repurchases of up to an aggregate of
3,150,000 shares, of which approximately 2,900,000 have been repurchased to
date. During the year ended December 31, 1994, the Company repurchased no shares
of Common Stock. On March 31, 1995, the Company issued 833,333 shares of Common
Stock from its treasury as partial consideration in the Neuromed Acquisition
and, concurrently with the closing of the Offering, will issue an additional
200,000 shares of Common Stock, which had been earned in July 1995 as additional
"earn-out" consideration. On November 6, 1995, the Company had 1,672,238 shares
in its treasury (after reserving for the issuance of such 200,000 shares) at a
cost of $3.6 million (including commissions). The Company does not anticipate
further repurchases during the foreseeable future.

                       SELECTED PRO FORMA FINANCIAL DATA
 
     The following unaudited pro forma condensed consolidated statements of
operations for the year ended December 31, 1994 and for the six months ended
June 30, 1995 reflect the historical accounts of the Company for those periods,
adjusted to give pro forma effect to the Neuromed Acquisition as if it had
occurred on January 1, 1994. The pro forma condensed consolidated statement of
operations for the year ended December 31, 1994 combines the statement of
operations of the Company for the twelve months ended December 31, 1994 and the
statement of operations of Neuromed for the twelve months ended October 31,
1994. The pro forma condensed consolidated statement of operations for the six
months ended June 30, 1995 combines the statement of operations of the Company
for the six months ended June 30, 1995 (which includes three months of Neuromed
operations since the March 31, 1995 acquisition) and the statement of operations
of Neuromed for the three months ended January 31, 1995.
 
     The pro forma condensed consolidated statements of operations and
accompanying notes should be read in conjunction with the Consolidated Financial
Statements of the Company and Neuromed and the related Notes thereto included
elsewhere in this Prospectus. Management believes the assumptions used in the
following statements provide a reasonable basis on which to present the pro
forma financial data. The pro forma financial data is provided for informational
purposes only and should not be construed to be indicative of the Company's
financial condition or results of operations had the transactions and events
described above been consummated on the date assumed and are not intended to
project the Company's financial condition or results of operations to any future
date or for any future period.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Consolidated
Financial Statements of the Company and the related Notes thereto included
elsewhere in this Prospectus.
 
OVERVIEW
 
     The Company designs, develops, manufactures and markets a variety of
healthcare products used primarily in cardiovascular surgery, interventional
pain management and intravenous fluid delivery applications. The Company
operates several stable and profitable product lines, including cardiovascular
products (such as pressure control valves, filters and surgical retracting
tapes), specialized intravenous fluid delivery tubing sets and accessories, and
pressure monitoring kits used primarily in labor and delivery.
 
     On March 31, 1995, the Company acquired all of the issued and outstanding
capital stock of Neuromed, which was held by Mr. William Borkan and his brother,
Mr. Burt Borkan. The Neuromed Acquisition has been accounted for as a purchase.
The Company paid the Borkans $15.4 million in cash ($200,000 of which was paid
in June 1995 as a purchase price adjustment) and issued them 833,333 shares of
Common Stock valued at $6.5 million. The Company also incurred $927,000 in
acquisition and financing costs. Depending on Neuromed's attainment of certain
sales objectives, the Company also agreed to pay the Borkans contingent
"earn-out" consideration in January 1996 and January 1997, payable in a
combination of cash and Common Stock. In June 1995, Mr. William Borkan was
elected to the Company's Board of Directors.
 
     In September 1995, the Company and Mr. William Borkan amended certain terms
of the Neuromed acquisition agreement. Under the amendment, (i) the Company
agreed to issue Mr. Borkan 200,000 additional shares of Common Stock
concurrently with the closing of the Offering and pay Mr. Borkan $1.5 million in
cash in January 1996 to satisfy the 1996 contingent payment obligation, which
had been earned in July 1995, (ii) the Company agreed to include all of the
Borkans' Common Stock (1,033,333 shares) in this Offering, (iii) Mr. Borkan
resigned from the Company's Board of Directors and relinquished his board
representation and attendance rights, (iv) Mr. Borkan relinquished his
registration rights, and (v) in the event the 1997 contingent earn-out payment
is fully earned, the Company agreed to pay Mr. Borkan an amount in cash equal to
$1.5 million plus the value of 200,000 shares of Common Stock at the net
Offering price. See "Certain Transactions."
 
     In connection with the Neuromed Acquisition, the Company entered into the
First Amended and Restated Credit Agreement dated March 31, 1995, with
NationsBank (the "Loan Agreement"), which provided for $15.0 million in senior
term financing and a $5.0 million working capital line of credit. The senior
term debt was utilized to pay most of the cash portion of the Neuromed purchase
price. The Company has also drawn down $4.5 million on the working capital line
of credit. This bank debt is collateralized by certain of the Company's assets,
including without limitation, accounts receivable, inventory, equipment,
furniture and other fixed assets, patents, trademarks and other intangible
property, and the Neuromed Common Stock, but excluding marketable securities in
excess of $2.0 million. NationsBank's lien also excludes the Company's real
property, building and certain equipment in Allen, Texas, which collateralize
financing provided in 1993 by MetLife Capital Corporation. The Company intends
to use the net proceeds it receives from the Offering to repay $11.9 million of
the senior term debt ($13.9 million is currently outstanding). See "Use of
Proceeds." The Company had received a commitment letter from NationsBank that
provided for the amendment of the working capital line of credit and the
addition of an acquisition line of credit if the Offering were consummated and
raised net proceeds to the Company of at least $17.0 million. Although the net
proceeds from the Offering are less than such stipulated amount, the Company
believes that it should be able to obtain satisfactory working capital and
acquisition lines of credit from NationsBank or another lender. See
"-- Liquidity and Capital Resources."

RESULTS OF OPERATIONS
 
COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 1995 AND 1994
 
     Revenues. Net revenue of $11.3 million for the six months ended June 30,
1995 was $4.1 million, or 56.5% above the level for the comparable 1994 period
of $7.2 million. This increase in net revenue during the first half of 1995
compared to the first half of 1994 was primarily attributable to revenue
generated by Neuromed, which was acquired on March 31, 1995. See "-- Overview"
and "Selected Pro Forma Financial Data." Net revenue from sales of the Company's
other products increased 8% during the six months ended June 30, 1995 compared
to the same period a year ago, primarily due to higher unit sales volume from
the Company's cardiovascular products. Management expects net revenue for the
remaining two quarters of 1995 to increase over the comparable periods during
1994 as a result of the inclusion of the Neuromed revenues in the Company's
financial statements.
 
     Gross Profit. Gross profit of $6.4 million for the six months ended June
30, 1995 was $3.2 million, or 100%, above the level for the comparable 1994
period. As a percentage of net revenue, gross profit increased during the first
half of 1995 to 56.6% as compared to 44.2% for the comparable 1994 period. This
increase in gross profit margin during the six months ended June 30, 1995
compared to the comparable period during 1994 was primarily attributable to the
revenue generated by Neuromed, since Neuromed's products contribute higher gross
profit margins than the Company's other product lines. Consequently, management
expects the Company's overall gross profit margin for the remaining two quarters
of 1995 to increase compared to the comparable 1994 periods.
 
     Operating Expenses. Research and development expense as a percentage of net
revenue increased from 21.3% during the six months ended June 30, 1994, to 22.1%
for the same period in 1995, and the dollar amount increased by $955,000. During
the first half of 1995, the Company continued development efforts on its MPS
system and related products. During the second quarter of 1995, the Company
assembled pre-production MPS units necessary for the validation testing needed
for the 510(k) filing with the FDA. Validation testing was completed and, as
previously noted, the Company filed the 510(k) with the FDA during August 1995.
There can be no assurance that FDA clearance will be obtained or that it will be
obtained without delay. Of the increase in research and development expense for
the six months ended June 30, 1995, $182,000 was research and development
expense attributable to Neuromed's products. The remainder of the increase
during the first half of 1995 compared to the first half of 1994 was primarily
the result of additional salary and contract labor expense from personnel
additions and increased consulting expense. Management expects research and
development expenditures for the remainder of 1995 to decrease from the first
half of 1995's level of $2.5 million because of substantial completion of the
development of the MPS system.
 
     Marketing, general and administrative expenses as a percent of net revenues
decreased to 31.1% for the six months ended June 30, 1995, compared to 32.9% for
the comparable period of 1994, and the dollar amount increased $1.1 million.
Marketing expense as a percentage of net revenue increased to 14.1% for the six
months ended June 30, 1995, compared to 12.3% for the same period during 1994,
and the dollar amount increased by $703,000. Of such increase, $439,000 was
Neuromed marketing expense. The remainder of the increase in marketing expense
was primarily the result of additional salary and benefit expense from personnel
additions, and increased travel, commission and convention expense. In
anticipation of 510(k) clearance, management anticipates hiring four additional
direct salespersons during the second half of 1995, and upon 510(k) clearance,
management expects to add five additional salespersons to market the MPS system
and related products. For the six months ended June 30, 1995, general and
administrative expense increased $433,000 compared to the same period in 1994,
but as a percentage of net revenues, decreased from 20.6% during the first half
of 1994 to 17.0% during the comparable 1995 period. This increase in expense for
the six month period of 1995 compared to 1994 was primarily attributable to
general and administrative expense of Neuromed, including amortization expense
of Neuromed intangibles.
 
     Loss from Operations. On March 31, 1995, the Company acquired all of the
capital stock of Neuromed in exchange for $15.4 million cash (excluding $927,000
of related acquisition and financing
 
                                       17
<PAGE>   18
 
costs) and 833,333 shares of Common Stock valued at $6.5 million (plus
additional contingent "earn-out" consideration). See "-- Overview" and "Certain
Transactions." Of the cash payment referred to above, $200,000 was made during
June 1995 as a result of a purchase price adjustment. Of the aggregate purchase
price, $10.5 million was identified as purchased in-process research and
development and in accordance with generally accepted accounting principles was
charged to expense as a non-recurring charge, with no related tax benefit,
during the six months ended June 30, 1995. See Note 2 of the Notes to
Consolidated Financial Statements. As a result, the loss from operations
increased from $719,000 for the six months ended June 30, 1994, to $10.1 million
for the comparable period during 1995. Excluding this charge, the Company
generated earnings from operations of $388,000 for the six months ended June 30,
1995 compared to a $719,000 loss for the comparable 1994 period, reflecting the
positive impact of the Neuromed Acquisition. Based on Neuromed's recent and
historical results of operations, management believes that the Neuromed
Acquisition will continue to have a favorable impact on earnings from operations
for the remainder of 1995 as compared to the comparable period during 1994,
although there can be no assurances to this effect.
 
     Other Income (Expense). Other income decreased to an expense of $501,000
during the six months ended June 30, 1995 compared to income of $178,000 during
the comparable 1994 period. This decrease was primarily the result of increased
interest expense. The Company incurred $15.0 million of long-term bank debt on
March 31, 1995, which was used to fund most of the cash payment of the Neuromed
Acquisition. See "-- Overview" and Notes 2 and 3 of the Notes to Consolidated
Financial Statements. Higher overall interest rates on borrowed money also
contributed to higher interest expense during the first half of 1995 as compared
to the first half of 1994. In addition, interest income in the first half of
1995 was lower than in the comparable period of 1994 due to reduced funds
available for investment and lower gains recognized on the sale of the Company's
investments. The Company anticipates that it will use the net proceeds from the
Offering to repay the senior term bank debt ($14.0 million outstanding at
September 26, 1995) and as much of working capital indebtedness ($4.5 million
outstanding at September 26, 1995) as is possible. See "Use of Proceeds."
 
     Net Loss. The net loss increased from $540,000 for the six months ended
June 30, 1994 to $10.6 million during the same period in 1995 as a result of the
aforementioned non-recurring charge for purchased in-process research and
development of $10.5 million incurred in connection with the Neuromed
Acquisition. Excluding this charge, the net loss for the six months ended June
30, 1995 was $113,000.
 
YEARS ENDED DECEMBER 31, 1994 AND 1993
 
     Revenues. Net revenue of $14.0 million for the year ended December 31,
1994, increased 2.6% from $13.6 million for the comparable 1993 period. Three of
the Company's product lines, however, contributed better results than the
overall 2.6% year over year increase. Net revenue of the Company's
cardiovascular products increased $604,000, or 11.5%, due to higher unit sales
volume from the Company's family of pressure control valves. Net revenue
generated by the Company's pressure monitoring kits increased $160,000, or
11.7%, due to higher unit sales volume. Net revenue generated by the Company's
nasogastric feeding tubes increased $108,000, or 48.2%. Of this increase,
$74,000 was due to higher unit sales volume with the remainder due to a price
increase. Net revenue generated by the Company's specialized tubing sets,
however, decreased by $518,500, or 7.7%, reflecting lower unit sales volume
largely attributable to a reduction in sales of specialized tubing sets used in
oncology to the Company's largest customer, the University of Texas System
Cancer Center (M.D. Anderson Hospital), due to lower hospital census.
 
     Gross Profit. Gross profit during 1994 decreased to $6.4 million compared
to $6.6 million in 1993, a reduction of $210,000. As a percentage of net
revenue, gross profit decreased to 45.6% in 1994 compared to 48.3% during 1993.
The decrease in gross profit during 1994 compared to 1993 resulted primarily
from the lower net revenue generated by the Company's specialized tubing sets.
Lower sales volume of this product line led not only to a reduction in actual
gross profit dollars from this product line, but also to a
 
                                       18
<PAGE>   19
 
reduction in gross profit margins for this product line, since manufacturing
volumes were reduced, thus resulting in higher overhead costs per unit.
 
     Operating Expenses. Research and development expense increased to $3.5
million during 1994 compared to the 1993 level of $1.9 million, and as a
percentage of net revenue increased from 14.0% to 25.3%. During 1994, the
Company continued development efforts on its MPS system and related products.
See "Business -- Research and Development." During June 1994, the Company
completed assembly of five MPS prototypes. In September 1994, the Company
determined that more time was needed to redesign the MPS prototypes into
pre-production units and delayed the anticipated December 1994 510(k) filing
with the FDA. The redesign was completed during December 1994. Increases in
research and development expense during 1994 compared to 1993 were primarily the
result of additional salary and contract labor expense from personnel additions,
increased prototype tooling, test material, consulting, and toxicology test
expenses. The Company also hired fourteen additional research and development
personnel during 1994.
 
     Marketing, general and administrative expense as a percent of net revenues
increased to 35.6% for 1994 compared to 32.2% for 1993, and the dollar amount
increased $577,000. Marketing expense remained relatively unchanged during 1994
as compared to 1993 and as a percentage of revenue, decreased from 14.1% during
1993 to 13.7% during 1994. General and administrative expense increased
$582,000, or 23.4%, during 1994 as compared to 1993, and as a percentage of net
revenue, increased from 18.2% during 1993 to 21.9% for 1994. This increase
during 1994 compared to 1993 was primarily the result of higher recruiting and
relocation expense, depreciation and amortization expense, health insurance
expense, employee relations expense and expenses related to a proposed
acquisition that was not consummated.
 
     Earnings (Loss) from Operations. Earnings from operations decreased from
earnings of $281,000 during 1993 to a loss of $2.1 million in 1994 as a result
of the aforementioned increases in research and development and general and
administrative expenses and the decrease in gross profit.
 
     Other Income (Expense). Other income decreased to $419,000 during 1994
compared to other income of $667,000 for the prior year. This decrease resulted
from an increase in interest expense. Interest expense increased during 1994 as
compared to 1993 by $488,000 primarily due to two pieces of debt which were in
place for all of 1994 but only in place during the fourth quarter of 1993.
During December 1993, the Company consummated a financing with MetLife Capital
Corporation which provided $4.4 million of long term financing for the Company's
new corporate headquarters constructed during 1993. In addition, the Company
increased borrowings against its working capital line of credit with NationsBank
during 1994.
 
     No income tax benefit was recognized for the Company's 1994 net operating
loss. Income tax expense during 1993 was $301,000.
 
     Net Earnings (Loss). Net earnings decreased from net earnings of $816,000
during 1993 to a net loss of $1.7 million in 1994 primarily as a result of the
decrease in earnings from operations (caused by lower gross profit and higher
general and administrative and research and development expenses) and the
decrease in other income discussed above. During May 1993, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 115, "Accounting for Certain Investments in Debt and Equity Securities." The
Company, as permitted under the Statement, elected to adopt the provisions of
the new standard at the end of fiscal 1993. The cumulative effect as of December
31, 1993 of adopting Statement No. 115 was to increase net income by $169,000,
resulting from the reversal of unrealized losses recorded during 1993. The
ending balance of stockholders' equity was decreased by $169,000 to reflect the
net unrealized holding loss on securities classified as available-for-sale
previously carried at the lower of cost or market.
 
                                       19
<PAGE>   20
 
YEARS ENDED DECEMBER 31, 1993 AND 1992
 
     Revenues. Net revenue of $13.6 million for 1993, was approximately the same
as net revenue for 1992. This flat net revenue comparison reflected the then
current weakness in the medical device industry. In the wake of the Clinton
Administration's initiatives on healthcare reform, many of the Company's
customers engaged in cost-cutting during the year and reduced inventories of
medical devices and disposables during 1993, causing what management believed to
be a transient reduction in demand. The Company believes that this weakness in
product demand and the reduction in inventory levels reflected the general
uncertainty in the hospital and health care industry prompted by proposed
federal legislation and the general pressure to reduce healthcare costs. Net
revenue generated by the Company's specialized tubing sets decreased by
$342,000, or 4.8%, during 1993 as compared to 1992, reflecting decreased unit
sales volume. A substantial portion of this decrease resulted from a reduction
in sales of specialized tubing sets used in oncology to the Company's largest
customer, the University of Texas System Cancer Center (M.D. Anderson Hospital).
Net revenue generated by the Company's pressure monitoring kits decreased
$175,000, or 11.4%, during 1993 as compared to 1992 from reduced unit sales
volume of transducers (pressure sensors).
 
     Net revenue generated by the Company's cardiovascular products, however,
increased $593,000, or 12.7%, during 1993 as compared to 1992, as a result of
three factors. First, $273,000 of the increase resulted from twelve months of
sales during 1993 from the ACTester product line while the 1992 period included
revenue only from the acquisition date of June 23, 1992 (six months). Second,
$112,000 of the increase resulted from the Company's introduction of a new
disposable product, Retroguard, during the second quarter of 1993. Finally, the
remainder of the increase resulted from a price increase on certain of the
Company's cardiovascular products.
 
     Gross Profit. Gross profit of $6.6 million for 1993 was approximately the
same as gross profit for 1992. As a percentage of net revenue, gross profit
increased to 48.3% in 1993 from 48.1% during 1992. Lower sales volume in the
Company's specialized tubing sets during 1993 as compared to 1992 led not only
to a reduction in actual gross profit dollars from this product line, but also a
reduction in gross profit margin for this product line since manufacturing
volumes were reduced during 1993, resulting in higher overhead costs per unit.
However, higher net revenue in the Company's cardiovascular products, which
typically generate somewhat higher gross profit margins than most of the
Company's other products, more than offset the shortfall in actual gross profit
dollars of the specialized tubing sets. Gross profit margin in the
cardiovascular product line increased during 1993 as compared to 1992, primarily
as a result of a price increase.
 
     Operating Expenses. Research and development expense increased to $1.9
million during 1993 compared to the 1992 level of $1.4 million, and as a
percentage of net revenue, increased from 10.2% to 14.0%. During 1992, the
Company commenced, and during 1993, continued development efforts on its MPS
brand of myocardial protection system and family of related disposable products.
Increases in expense during 1993 as compared to 1992 were primarily related to
additional salary and contract labor expense from personnel additions, increased
consulting and prototype tooling expense.
 
     Marketing, general and administrative expense as a percent of net revenues
increased to 32.2% for 1993 compared to 30.4% for 1992, and the dollar amount
increased $258,000. Marketing expense increased $270,000, or 16.4%, during 1993
as compared to 1992, and as a percentage of net revenue, increased from 12.1%
during 1992 to 14.1% for 1993. This increase resulted primarily from increased
travel expense, samples expense, and advertising and promotional expense to
support the Company's sales efforts for its perfusion and other cardiovascular
product lines. General and administrative expense remained relatively unchanged
during 1993 as compared to 1992.
 
     Earnings (Loss) from Operations. Earnings from operations increased from a
loss of $222,000 during 1992 to earnings of $281,000 for 1993. Results for the
1992 period included a non-recurring charge of $1.2 million to write-off the
assets of a discontinued business. Excluding this charge, earnings from
operations decreased from $1.0 million during 1992 to $281,000 during 1993 as a
result of the increase in marketing and research and development expense
discussed above.
 
                                       20
<PAGE>   21
 
     Other Income (Expense). Other income increased to $667,000 during 1993 as
compared to other income of $473,000 for the prior year. During 1993, the
Company recorded an expense of $174,000 related to the move to its new corporate
headquarters in Allen, Texas. This expense was largely comprised of moving costs
(including employee relocation costs) and the cancellation of two facility
leases. The Company also recorded an expense of $169,000 to reduce the value of
its investment portfolio to market value. Results for 1993 include a gain on
sale of marketable securities of $462,000, an increase of $325,000 from 1992.
These gains were generated by the sale of substantially all of the Company's
municipal bond portfolio and other interest rate sensitive investments which had
appreciated in value due to falling interest rates. The Company's decision to
significantly expand its research and development efforts reduced its need for
tax-free investment income.
 
     Income tax expense increased $243,000 in 1993 compared to 1992 primarily as
a result of the increase in earnings.
 
     Net Earnings. Net earnings increased from $194,000 during 1992 to $816,000
during 1993 primarily as a result of the aforementioned non-recurring charge
during 1992 of $1.2 million for the write-off of a discontinued business. Net
earnings for 1993 benefited by the cumulative effect of a change in accounting
principle of $169,000 discussed above.
 
QUARTERLY OPERATING DATA
 
     The following table sets forth certain unaudited operating data for the
four quarters in 1993 and 1994 and the first and second quarters of 1995. In the

     The level and timing of research and development expenditures for the MPS
system and related products has had a significant effect on the quarterly
results of operations during the past several years. In addition, although the
Company's base business (prior to the Neuromed Acquisition) has been stable on
an annual revenue basis for the past few years, the Company experiences
quarterly revenue

fluctuations which affect results. Management currently anticipates results for
the remainder of 1995 will compare favorably to the corresponding periods during
1994 as a result of the Neuromed Acquisition and a decrease in the level of
research and development expenditures for the second half of 1995 compared to
the first half due to the substantial completion of, and filing of the 510(k)
for, the MPS system.
 
     Results of operations on a quarterly basis in the future will continue to
depend upon numerous factors including: (i) base business fluctuations; (ii)
market acceptance of new products; (iii) timing of regulatory approvals; (iv)
marketing expenditures for new product introductions; (v) the Company's ability
to manufacture its products efficiently; (vi) timing of research and development
expenditures; and (vii) acquisitions.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash, cash equivalents and marketable securities totaled $4.7 million at
June 30, 1995, a decrease of $556,000 from 1994 year-end. Working capital
(current assets less current liabilities) was $10.8 million with a current ratio
of 2.88 to 1 at June 30, 1995.
 
     On March 31, 1995, the Company acquired all of the outstanding capital
stock of Neuromed. The Company paid $15.4 million in cash and 833,333 shares of
Common Stock valued at $6.5 million for the Neuromed stock. Of the cash payment
referred to above, $200,000 was paid in June 1995 as a result of a purchase
price adjustment. The Company also incurred $927,000 in acquisition and
financing costs. In July 1995, the Company recorded additional "earn-out"
consideration of 200,000 shares of Common Stock to be issued upon the closing of
the Offering (or if the Offering is not completed, in January 1996) and $1.5
million in cash payable January 1996. In January 1997 (assuming certain sales
objectives are fully met), the Company is obligated to pay an amount in cash
equal to $1.5 million plus the value of 200,000 shares of Common Stock at the
net Offering price, all as final earn-out consideration. See "-- Overview" and
"Certain Transactions."
 
     In connection with the purchase, the Company determined that the operations
of Neuromed will be relocated to Texas by the end of the first quarter of 1996.
The Company is in the process of finalizing the estimated costs of the
relocation which will be recorded in the third quarter of 1995 as an adjustment
to costs in excess of net assets acquired.
 
     On March 31, 1995, the Company entered into the Loan Agreement with
NationsBank which provided $15.0 million of senior term financing utilized to
pay most of the cash portion of the Neuromed purchase price and a $5.0 million
working capital line. At June 30, 1995, the Company had borrowings under the
working capital line of $4.2 million with a weighted average interest rate of
9.09%. The Company intends to use the net proceeds from the Offering to repay
the senior term debt ($13.9 million of which is currently outstanding) and as
much of the working capital indebtedness as possible ($4.6 million of which is
currently outstanding). Upon repayment, NationsBank would release its liens on
the Company's assets. See "Use of Proceeds."
 
     On September 25, 1995, NationsBank issued the Company a commitment letter
providing for the amendment of the $5.0 million working capital line and the
addition of a $15.0 million acquisition line under certain conditions. Under the
commitment letter, the amended working capital line of credit would be
collateralized by the Company's accounts receivable and inventory and the
acquisition line, if drawn upon, would be collateralized by the Company's
remaining unencumbered assets. Management expects to negotiate a dividend
limitation that would apply if the acquisition line is utilized. Although the
net proceeds from the Offering are less than the amount required under the
commitment letter to obtain such financing, the Company believes that it should
be able to obtain satisfactory working capital and acquisition lines of credit
from NationsBank or another lender. There can, of course, be no assurance that a
definitive agreement will be reached with NationsBank or any other financing
source or that any loan agreement would be on the same or comparable terms to
the Company's current indebtedness. The Company has no immediate plans to
utilize an acquisition facility if such facility were indeed obtained.
 
                                       22
<PAGE>   23
 
     The Company's investment strategy is to maximize its dividend and interest
yields on cash not currently employed in operating activities by investing in
highly liquid investments. The Company's current investment portfolio consists
primarily of interests in publicly traded real estate investment trusts and
publicly traded investment grade corporate preferred stocks (which qualify for
70% dividend exclusion for tax purposes). These investments generally yield
higher returns than certificates of deposit or treasury bills, but with a higher
market value exposure to interest rate risk. Tightening of monetary policy by
the Federal Reserve during 1994 led to a significant rise in both short- and
long-term interest rates, thereby negatively affecting the value of interest
rate sensitive investments. Consequently, at December 31, 1994, the Company's
investment portfolio had declined in value by $918,000. As required by FAS 115,
this decline is reflected as a decrease in stockholders' equity through the
component entitled "unrealized loss on marketable securities." During the first
half of 1995, interest rates fell, resulting in an increase in the value of the
Company's portfolio of $444,000, thereby decreasing the unrealized loss
component of stockholders' equity to $474,000 at June 30, 1995. During the first
half of 1995, the Company was a net seller of marketable securities in the
amount of $1.2 million. The Company's investment strategy has realized
cumulative net gains on its investments of over $1.0 million during the past
three years while continuously realizing higher interest and dividend yields
compared to certificates of deposit or treasury bills. At June 30, 1995, no
individual security represented more than 10% of the total portfolio or 1 1/4%
of total assets. The Company's investment policies prohibit the use of
derivative financial instruments.
 
     The Company spent $995,000 for additions to property, plant and equipment
during the six months ended June 30, 1995, most of which were for manufacturing
toolings and equipment for the MPS system and related products. Management
expects capital expenditures for the remainder of 1995 to approximate $200,000.
 
     Following the Offering, management believes that current cash, cash
equivalents and marketable securities, funds generated from operations, and if
necessary, funds provided by a working capital line of credit, will be
sufficient to satisfy normal cash operating requirements and capital
requirements through the end of 1996.
 
CURRENCY FLUCTUATIONS
 
     Substantially all of the Company's international sales are denominated in
U.S. dollars. Fluctuations in currency exchange rates in other countries could
reduce the demand for the Company's products by increasing the price of the
Company's products in the currency of the countries in which the products are
sold, although management does not believe currency fluctuations have had a
material effect on the Company's results of operations.
 
SUMMARY THIRD QUARTER OF 1995 AND NINE MONTHS OPERATING RESULTS
 
     On November 2, 1995, the Company reported preliminary unaudited results for
the third quarter of 1995. The following preliminary unaudited results for the
third quarter of 1995 and the nine months ended September 30, 1995 include
results of Neuromed from April 1, 1995. Net revenues for the third quarter ended
September 30, 1995 were $6.8 million, compared to $3.5 million for the same
quarter a year ago, a 94.3% increase. Net earnings for the third quarter were
$91,000, or $.01 per share, compared to a net loss of $489,000, or $(.09) per
share for the prior year quarter. Operating results reflected research and
development costs for the 1995 quarter of $1.2 million compared to $870,000 in
the 1994 quarter.
 
     For the nine months ended September 30, 1995, net revenues were $18.1
million compared to $10.7 million for the same period a year ago, which
represents a 69.2% increase. The loss for the nine month period was $10.5
million or $(1.69) per share, after taking into account the $10.5 million non-
recurring charge for purchased in-process research and development incurred in
connection with the Neuromed Acquisition. See "Selected Consolidated Financial
Data" and "Selected Pro Forma Financial Data." This nine month period loss
compares to the 1994 period loss of $1.0 million or $(.20) per share. Research
and development costs for the 1995 period were $3.6 million, compared to $2.4
million for the comparable 1994 period.

                                    BUSINESS
GENERAL
 
     Quest designs, develops, manufactures and markets a variety of healthcare
products used primarily in cardiovascular surgery, interventional pain
management and intravenous fluid delivery applications. The Company operates
several stable and profitable product lines, including cardiovascular products
(such as pressure control valves, filters and surgical retracting tapes),
specialized intravenous fluid delivery tubing sets and accessories and pressure
monitoring kits used primarily in labor and delivery. The Company has levered
these product lines, its existing corporate infrastructure and its core
competencies in manufacturing, engineering and regulatory affairs to expand into
new markets as evidenced by the internally funded development of the Quest MPS
myocardial protection system, an innovative and sophisticated system designed to
manage the delivery of solutions to the heart during open-heart surgery. In
addition, the Company recently entered the interventional pain management market
by acquiring Neuromed, which designs, develops, manufactures and markets a line
of electronic SCS devices used to manage chronic severe pain.
 
     In 1991, Quest acquired two companies that manufactured and marketed
various cardiovascular products, significantly enhancing the Company's presence
in the cardiovascular products marketplace. In 1992, Quest identified a real and
immediate need in this marketplace for an automated and integrated myocardial
protection system that would be versatile, easy to use, efficient to monitor and
cost-effective. Myocardial protection is the process of arresting and caring for
the heart during open-heart surgery. The Quest MPS system is designed to
integrate key functions relating to the delivery of solutions to the heart such
as varying the rate and ratio of oxygenated blood, crystalloid, potassium and
other additives, and controlling temperature, pressure and other variables to
allow simpler, more flexible and cost-effective management of this process. The
MPS system employs advanced pump, temperature control and microprocessor
technologies and includes a line of captive and non-captive disposable products.
The Company filed a 510(k) for its MPS system with the FDA in August 1995.
 
     In its continuing effort to expand into potentially high growth niche
markets in the medical device industry, the Company acquired Neuromed in March
1995. SCS is gaining increased acceptance as a viable, efficacious and
cost-effective treatment alternative to repeat back surgeries for relieving
chronic severe back pain. The Company believes that its recently introduced
CompuStim products, which are powered by radio frequency transmitters external
to the body, are the technological leaders in the field. The Company is
currently test marketing PainDoc, a pen-based computer system that works in
tandem with the Company's CompuStim devices to assist physicians and their
patients in optimizing the performance of the Company's SCS devices both pre-
and post-operatively.
 
     Since its founding in 1979, the Company has developed, manufactured and
marketed specialized intravenous fluid delivery tubing sets and accessories sold
primarily to major hospitals in the United States. Over the last several years,
the revenues generated by this product line, a substantial component of the
Company's historical base business, have significantly aided the funding of the
Company's research and development efforts. The Company manufactures and markets
over 70 distinct models of specialized intravenous fluid delivery tubing sets.
 
BUSINESS STRATEGY
 
     The Company's strategy is to capitalize on its existing corporate
infrastructure and apply its core competencies in medical device manufacturing,
engineering and regulatory affairs to expand its presence in targeted niche
markets. The Company believes that this strategy has enabled it to expand into
new product lines with high growth potential such as the MPS system and family
of disposable products, and into new niche markets such as the spinal cord
stimulation market within the larger interventional pain management marketplace.
The Company has internally funded the research and development expense involved
in designing, developing and pursuing regulatory approval for products such as
the MPS system. The Company believes that the historical stability of the
revenue stream generated by its base business has been an important factor in
the Company's ability to develop new and expanded product lines.
 
                                       24
<PAGE>   25
 
     Quest intends to continue pursuing its strategy through internal product
development and acquisitions, with particular emphasis on the cardiovascular and
interventional pain management markets. This strategy was exemplified by the
Company's acquisition of two companies in 1991 that significantly enhanced the
Company's presence in the cardiovascular market, and its subsequent development
of the MPS system and related disposables. Quest's strategy was further
demonstrated by the Company's entry into the interventional pain management
market through the Neuromed Acquisition.

CARDIOVASCULAR
 
     BACKGROUND. According to industry sources, approximately 700,000 open-heart
surgeries were performed worldwide in 1994, and approximately 400,000 coronary
bypass surgeries are performed annually in the United States. These complex
procedures require the extensive use of various disposables, which may include
the Company's valves, filters and traps. With pronounced increases in average
cardiovascular patient age, number of repeat open-heart surgical procedures, and
duration and complexity of open-heart surgical procedures, the process of
arresting and caring for the heart ("myocardial protection") has become a focal
point for the cardiovascular surgeon and the perfusionist. The perfusionist is
the clinical specialist who operates the equipment that manages the delivery of
blood and other fluids to the body's tissues during open-heart procedures.
Myocardial protection is accomplished through the controlled delivery to the
heart muscle of cardioplegia, a group of solutions including oxygenated blood,
crystalloid, an arresting agent (usually potassium), medication and nutrients,
and is used in virtually all open-heart procedures performed in the United
States and a majority of the procedures performed worldwide.
 
     VALVES, FILTERS AND TRAPS. The Company manufactures and markets a line of
proprietary specialized pressure control valves, pre-bypass and arterial line
filters and bubble traps, which are used by the perfusionist during
cardiopulmonary bypass surgery. Pressure control valves are placed in the
suction line to "vent," or decompress, the heart. These valves serve a number of
functions, including the maintenance of vacuum at a safe and consistent level to
minimize heart muscle tissue damage, as well as the prevention of inadvertent
and potentially catastrophic retrograde air flow into the heart. In 1993 and
1994, respectively, the Company introduced to the market two extensions of its
pressure control valve technology, the RetroGuard valve and the PlegiaGuard
valve. The RetroGuard valve is used with centrifugal pumps to prevent potential
retrograde blood flow and possible air embolism. The PlegiaGuard valve is used
to relieve overpressure in the cardioplegia line in the event that the line
becomes inadvertently clamped or occluded. The Company's arterial line filters
and bubble traps are used in the bypass circuit to remove air and other
potentially dangerous matter from the blood prior to the blood's return to the
patient. The Company's pre-bypass filters are used to flush the circuit external
to the patient's body prior to the initiation of the bypass procedure to
eliminate man-made debris within the lines.
 
     SURGICAL TAPES AND OTHER PRODUCTS. The Company also manufactures and
markets surgical retracting tapes under the trademark Retract-O-Tape, a product
line of silicone elastomer surgical tubing used to apply traction to and occlude
blood vessels during surgical procedures. The Company's surgical tapes are
hollow tubes, sealed at both ends to trap air, which resist collapsing when they
come into contact with a body structure. The Company's ACTester product line
consists of instrumentation and associated disposables used to measure the
activated clotting time of blood.
 
     MPS SYSTEM. In 1992, based on discussions with perfusionists and
cardiovascular surgeons regarding the logistical limitations of existing
cardioplegia delivery systems, the Company identified a real and immediate need
for an automated and integrated myocardial protection system that would be
versatile, easy to use, efficient and cost-effective. Over the past several
years, cardiovascular surgeons have developed advanced myocardial protection
protocols for open-heart surgery that significantly complicate the safe and
efficient administration of cardioplegia delivery using existing systems.
Protocols now call for warm or cold cardioplegia, various levels of potassium,
retrograde or antegrade cardioplegia flow, and a number of other variables.
Existing cardioplegia delivery systems are limited in their ability to
accommodate these evolving protocols, and are also difficult to control and
monitor due to the number of different components and protocol variables. Based
on its reengineering of the conceptual approach to cardioplegia delivery, the
Company designed the MPS system to address the limitations of existing
cardioplegia delivery systems. The Company then commissioned an independent
research firm to survey over 150 surgeons and perfusionists to confirm the
market demand for an automated and integrated approach to managing cardioplegia
delivery.
 
                                       26
<PAGE>   27
 
     The Company subsequently developed, and in August 1995 filed a 510(k) with
the FDA for, the MPS system. This system, which employs advanced pump,
temperature control and microprocessor technologies, is designed to enable the
perfusionist to vary the blood/crystalloid ratio and potassium concentration,
maintain a constant blood temperature, and maintain a constant delivery pressure
through an automated and integrated device. The Quest MPS instrument is designed
to provide this flexibility through the simple setting of dials on its control
panel. The Company believes that the MPS system will simplify the cardioplegia
delivery process and thus improve the safety of this process by reducing the
risk of human error.
 
     As a part of the MPS system, the Company has designed and developed a
"captive" disposable delivery set, which fits into the instrument and is
necessary to the operation of the instrument. The Company has also designed and
developed additional "non-captive" disposable tubing and other accessories for
use with the MPS system. These non-captive disposables are not integral to the
operation of the instrument and can be purchased from other manufacturers. The
Company has received FDA clearance to market certain of its non-captive
disposables through the submission and approval of 510(k)s, and expects to begin
marketing such products in 1995.
 
INTERVENTIONAL PAIN MANAGEMENT
 
     BACKGROUND. Within the multi-billion dollar worldwide market for
interventional pain management products and services, the market for spinal cord
stimulation products has begun to grow significantly in recent years. SCS
devices employ neurostimulation, the process of electrically stimulating the
spinal cord to reduce chronic severe neuropathic (as opposed to acute) pain by
"masking" the pain signals sent to the brain. Neuropathic pain usually arises
from nerve damage. SCS device implantation manages the pain associated with
failed back syndrome (resulting from certain spinal disorders or unsuccessful
spinal cord surgery), peripheral neuropathy, phantom limb or stump pain,
ischemic pain and reflex sympathetic dystrophy. Traditionally selected as a
treatment alternative after less invasive therapies and repeat spinal cord
surgeries have failed to alleviate pain, SCS is gaining increased acceptance
among prescribing physicians as a treatment alternative because it is
reversible, relatively noninvasive and increasingly effective. The number of
domestic SCS procedures has grown from approximately 4,100 in 1991 to over 5,800
in 1993, representing approximately a 40% increase over two years. A majority of
SCS patients are between 40 and 59 years old, have had three to four previous
back surgeries and have experienced chronic back pain for several years. The
Company believes that there are currently approximately $80 to $90 million in
annual domestic sales of SCS products, based on its assumptions that (i) the
number of annual domestic procedures performed grows at a 20% annual rate, and
(ii) the average SCS device sells to hospitals for approximately $12,500.
 
     Management believes that a number of factors are driving the increased
acceptance and performance of SCS products: technical advances in equipment
leading to more predictable and successful outcomes; physician awareness and
training; an expanding client base; and potential cost containment compared to
other approaches for treating chronic back pain, especially the treatment
alternative of repeat back surgeries. The average SCS procedure, including
device, hospital and physician expense, costs approximately $25,000, and
compared to the expense of three to four repeat back surgeries, is
cost-effective. In addition, most back surgeries are performed in a hospital and
require a hospital stay, while SCS procedures are typically performed on an
out-patient basis.
 
     The market for SCS devices is currently divided between RF-coupled devices,
which use an external power source, and fully implantable systems known as
internal pulse generator ("IPG") devices. The Company believes that IPG devices
currently account for a substantial majority of the number of SCS procedures
performed, with RF-coupled devices accounting for the remainder. The Company
designs, develops, manufactures and markets RF-coupled SCS devices. The primary
advantages of the RF-coupled device include the simple replacement or recharge
of the external battery pack, and relatively lower overall cost. Although an IPG
device provides the convenience of a completely internalized system, IPG devices
involve added cost, complexity and risk because repeat surgeries are required to
replace the IPG power source. The Company believes that managed care and overall
cost
 
                                       27
<PAGE>   28
 
sensitivity may lead to increased selection of RF-coupled devices. Moreover, the
latest generation SCS devices generally include more electrodes and dual channel
receivers, both of which consume more electrical energy than an implanted power
source can practically deliver over an extended period of time. Consequently,
the Company believes that RF-coupled devices are beginning to gain market share.
 
     SCS DEVICES. The Company's SCS systems consist of three primary components:
leads, a receiver and a transmitter. The leads are most commonly placed through
the skin into the spinal column's epidural space. This procedure is similar to
that employed by physicians to administer drugs for anesthesia and other common
medical applications. Typically, one or two leads are inserted, each of which
has multiple electrodes that can be used to stimulate the targeted nerve roots
of the spinal cord. Each lead is then connected to the receiver, which is
implanted under the skin on the side of the abdomen. The receiver contains
electronics that receive RF energy and data from a source (the transmitter)
outside the body, and delivers the prescribed electrical pulses to the leads.
The transmitter is approximately the size of a pager, and is typically worn on a
belt. Since it is external to the body, the transmitter can be easily programmed
and serviced as needed, and its battery can be simply recharged or replaced.
 
     Neuromed introduced its first product, the Multiprogrammable Spinal Cord
Stimulator, or Multistim, in 1979. Since that time, Neuromed has played a
significant role in the development of SCS products. Multistim incorporated a
quadrapolar electrode system within a single lead, and was considered a major
innovation in the field of neurostimulation because it significantly reduced
surgical time, cost and risk. Since the launch of Multistim, Neuromed has
developed and introduced a wide range of RF-coupled SCS systems with a variety
of options to accommodate different applications and degrees of pain.
 
     The Company's recently introduced CompuStim systems include four, eight and
sixteen electrode leads; specialty leads for peripheral applications; single and
dual channel receivers; and rechargeable transmitters and antennae. The Company
believes that the CompuStim product line's multi-electrode leads and
multiprogrammable electronics technology have changed the manner in which
neurostimulation is performed worldwide. For example, Neuromed's "Dual Octrode"
device, a recently introduced system of dual leads with eight electrodes each,
creates a targeted current density that appears to be especially effective in
relieving chronic axial (or body trunk) pain. Previously, quadrapolar SCS
systems only relieved the leg pain associated with failed back syndrome.
Industry sources support the view that the Dual Octrode device provides improved
pain relief to both the legs and the back. Consequently, although the Dual
Octrode device has only been on the United States market since February 1995, it
now accounts for approximately 60% of Neuromed's current product revenue and, in
the Company's judgment, is the technological leader in the SCS field. The
Company believes that the long term results of SCS in the treatment of pain have
improved as a result of the flexibility of Neuromed's designs, epitomized by the
Dual Octrode product. Moreover, the ease of use of the system has expanded the
potential market for these products.
 
     Use of the Company's current SCS products in certain operating modes
consumes relatively greater amounts of electrical current, reducing the
operating time of the rechargeable, externally worn battery packs. In addition,
certain of the Company's current SCS products have experienced switch failures
attributable in significant part to a specific brand of switches. These switches
are no longer being purchased and are being replaced by a new switch that
appears not to exhibit the same problems. Patient misuse has also contributed to
the switch failures. Finally, the Company's SCS products have exhibited some
intermittent stimulation, which the Company believes is attributable to several
factors including improper antenna placement, physicians or patients adjusting
stimulation below perceptible levels, improper receiver implant placement
techniques and lead movement. The Company is developing and implementing
improved patient and physician communications and training programs and is
pursuing product design enhancements and improvements to address these matters.
 
                                       28
<PAGE>   29
 
     PAINDOC. In addition to its current array of SCS devices, the Company is
developing and testing PainDoc, a pen-based computer system that is designed to
assist physicians and their patients in optimizing the performance of the
Company's SCS devices both pre- and post-operatively. PainDoc interfaces with
the Company's CompuStim transmitters to optimize SCS therapy and document
treatment outcomes. PainDoc allows the physician to input information regarding
the patient's description of the location and intensity of the patient's pain.
The resulting "pain map" is then analyzed by the computer to assess and select
the most effective stimulation sets, or combination of multi-electrode
stimulation arrays, to treat the pain. The selected arrays are uploaded into the
patient's CompuStim transmitter. After a trial period, the patient reports to
the physician the location and level of pain relief. These trial results are
uploaded back into PainDoc for the physician's objective review and analysis.
The physician can visually compare the patient's pain map against a stimulation
map and assess whether desired levels of pain relief have been obtained and
whether excess stimulation has been delivered. This process can be effective in
targeting the location of desired pain relief, reducing the patchiness of pain
relief delivered by many SCS devices and reducing or eliminating
overstimulation.
 
     PainDoc enables the physician to program up to 24 different stimulation
sets delivering electrical stimulation every 50 milliseconds to expand pain area
coverage and relief. The Company believes that PainDoc should also allow
physicians to create a broad based database tool that, by using a standardized
methodology, will enable physicians to share and compare outcomes data, which
can then be used to deliver more efficacious pain relief to individual patients.
The Company believes that PainDoc and CompuStim devices used in tandem should
significantly enhance the effectiveness, flexibility and precision of managing
chronic neuropathic pain. The Company expects PainDoc to promote the selection
of the Company's CompuStim devices for SCS procedures, especially as SCS devices
become more complex and the pain management process becomes more refined. In
October 1995, the Company received 510(k) approval from the FDA to market
PainDoc as an interactive medical treatment device. See "-- Government
Regulation."
 
     NEW PRODUCT OPPORTUNITIES. The Company believes that significant
opportunities for its SCS technology exist, both in the expansion of possible
applications of its existing products and in the development of new products,
specifically for patients afflicted with peripheral vascular disease, angina,
Parkinson's disease and motor disorders resulting from spinal cord injury or
paralysis. In addition, the Company currently plans to develop other pain
management products, which may include pumps, catheters, ports, needles and
scopes. In October 1995, the Company licensed certain pump technology that would
allow it to develop, manufacture and market implantable drug pumps that could be
used in interventional pain management applications, as well as in cancer
treatment and other applications. FDA approval for use of these pumps in humans
will be required.
 
INTRAVENOUS FLUID DELIVERY
 
     Since its founding in 1979, the Company has developed, manufactured and
marketed specialized intravenous fluid delivery tubing sets and accessories sold
primarily to major hospitals in the United States. Over the last several years
the revenues generated by this product line, a substantial component of the
Company's historical base business, have significantly aided the funding of the
Company's research and development efforts. The Company's core competencies in
medical device manufacturing, engineering and regulatory affairs have largely
been developed as a consequence of its experience with intravenous fluid
delivery products, including the electronic intravenous pump and associated
disposables business that was sold in 1987.
 
     The Company manufactures and markets over 70 distinct models of specialized
intravenous fluid delivery tubing sets, which can be broken down into two major
product categories -- Multiport(R) sets and anesthesia sets. Hospitals
frequently require specialized disposable intravenous tubing sets for more
complex therapy procedures employed in anesthesia administration, intravenous
feeding, intensive care and cancer therapy. The Company's intravenous tubing
sets generally consist of specialized
 
                                       29
<PAGE>   30
 
tubing and connector variations that distinguish them from standard intravenous
sets. The Company also manufactures and markets injection sites used in heparin
and other medication administrations.
 
     The Company has one patented specialized tubing set, purchased primarily by
the University of Texas System Cancer Center (M.D. Anderson Hospital), which is
used to deliver multiple drugs for complex chemotherapy applications. M.D.
Anderson accounted for $3.4 million, $3.1 million, $2.7 million and $1.5
million, or 25%, 23%, 19% and 14%, of the Company's net revenues for the years
ended December 31, 1992, 1993 and 1994 and the six months ended June 30, 1995,
respectively.
 
OTHER PRODUCTS
 
     The Company also designs, manufactures and markets other products for the
healthcare industry, including pressure monitoring kits used in labor and
delivery procedures and various critical care applications. The Company's
intrauterine pressure monitoring devices are used to determine pressure within
the mother's uterus primarily during high risk labor and delivery. Approximately
25% of the nearly four million births occurring annually in the United States
are categorized as "high risk" due to factors such as obesity, drug use,
disease, age or low fetus weight. During these procedures, a catheter is
inserted into the mother's uterus to measure uterine fluid pressure. This
information allows the clinician to monitor the progression of labor and to
determine whether intervention is necessary or advisable. The Company's
intrauterine pressure monitoring devices are marketed as kits containing all of
the components required to measure uterine fluid pressure.
 
RESEARCH AND DEVELOPMENT
 
     Since 1992, the Company has focused its research and development efforts on
designing and developing the MPS system and related products. The Company spent
$9.0 million on the research and development of its MPS system and related
products, representing over 92% of the Company's research and development
expense since 1992. Although the Company plans to continue engaging in ongoing
research and development to introduce new products, enhance the effectiveness,
ease of use, safety and reliability of existing products and expand the
applications for which its products are appropriate, particularly in the
cardiovascular and interventional pain management fields, the Company expects
research and development expense to decline in the near term, as a result of
completing development of the MPS system and certain related products in August
1995.
 
     As of November 6, 1995, the Company had an in-house research and
development staff of 22 engineers, technicians and designers, down from a peak
number of 49 in April 1995. This staff has worked closely with cardiothoracic
surgeons and perfusionists, hospital administrators, other healthcare
professionals and software and hardware engineers to understand the market need
for an integrated system dedicated to myocardial protection, and to design and
develop the MPS system and related disposables. The Company expects to continue
engaging in this collaborative effort to identify new niche market opportunities
and to design and develop innovative and cost-effective products and
enhancements, principally in the areas of cardiovascular surgery and
interventional pain management. Research and development expense in 1992, 1993,
1994 and the first half of 1995 was $1.4 million, $1.9 million, $3.5 million and
$2.5 million, respectively.
 
MANUFACTURING
 
     The Company manufactures and packages certain cardiovascular products (such
as pressure control valves, filters, traps and surgical retracting tapes) and
intravenous fluid delivery products at its primary manufacturing facility in
Allen, Texas. This facility received ISO 9001 certification (for design and
manufacturing processes) in July 1995. See "Business -- Government Regulation."
Although the Company currently manufactures its line of SCS devices and related
products at its ISO 9002 certified (manufacturing only) facility in Fort
Lauderdale, Florida, the Company plans to transition this operation to the Allen
facility during the fourth quarter of 1995 and the first quarter of 1996.
Finally, the
 
                                       30
<PAGE>   31
 
Company manufactures certain cardiovascular products at a facility in Orange
County, California, and will continue to do so for the foreseeable future.
 
     The Company's manufacturing processes consist of the assembly of standard
and custom component parts and the testing of completed products. The Company
subcontracts with various suppliers to provide it with the quantity of component
parts necessary to assemble its products. Almost all of these components are
available from a number of different suppliers, although certain components are
purchased from single sources, who manufacture these components from the
Company's toolings. For example, the Company relies on single suppliers for two
separate components of the specialized oncology intravenous tubing set that the
Company supplies to the University of Texas System Cancer Center (M.D. Anderson
Hospital), the Company's largest customer. The Company believes that there are
alternative and satisfactory sources for single-sourced components, although a
sudden disruption in supply from one of these suppliers could adversely affect
the Company's ability to deliver the finished product on time. The Company owns
its own molds for production of a majority of the components used in specialized
tubing sets and cardiovascular products. Consequently, in the event of supply
disruption, the Company would be able to fabricate its own components or
subcontract with another supplier, albeit after a delay in the production
process.
 
     The Company devotes significant attention to quality control. Its quality
control measures begin at the manufacturing level where components are assembled
in a "clean room" environment designed and maintained to reduce product exposure
to particulate matter. Products are tested throughout the manufacturing process
for adherence to specifications. Finished components are shipped to outside
processors for sterilization through radiation or treatment with ethylene oxide
gas. After sterilization, the products are quarantined and tested before they
are shipped to customers.
 
     Skills of assembly workers required for the manufacture of medical products
are similar to those required in typical assembly operations. The Company
believes that workers with these skills are readily available in the Dallas,
Fort Lauderdale and Orange County areas.
 
SALES AND MARKETING
 
     The Company markets most of its cardiovascular products and intravenous
fluid delivery tubing sets through direct contact with hospitals, independent
sales representatives, marketing arrangements with certain distributors and, to
a lesser extent, through telemarketing and direct mail. In addition, the Company
employs two sales managers who oversee the distributors who sell the Company's
cardiovascular products and pressure monitoring kits. The Company plans to
market its MPS system and family of related products domestically through a
direct sales force operating on a sales team approach. In anticipation of 510(k)
clearance, the Company has hired one sales manager and anticipates hiring
approximately four additional sales managers by the end of 1995, and upon 510(k)
clearance, to add approximately five additional salespersons to market the MPS
system and related products. The Company plans to market the MPS system and
related products internationally through specialty distributors. The Company
derives approximately 80% of net revenues attributable to its cardiovascular
products from domestic sales and approximately 20% from European, Australian and
Japanese sales.
 
     Neuromed has historically relied on specialty distributors to market its
SCS devices, and the Company expects to continue this sales and marketing
strategy. The Company employs two sales managers who oversee these specialty
distributors. The primary medical specialists the Company targets in its
marketing efforts are anesthesiologists, neurosurgeons and orthopedic surgeons.
Although neurosurgeons were the first practitioners to use SCS applications,
anesthesiologists now account for a greater percentage of sales as the relative
number of these practitioners has grown and as the understanding and acceptance
of SCS treatment has increased. The Company derives approximately 80% of net
revenues attributable to its SCS devices from domestic sales and approximately
20% from European and Australian sales. See "Risk Factors -- Dependence on
Distributor Sales."
 
                                       31
<PAGE>   32
 
     The University of Texas System Cancer Center (M.D. Anderson Hospital)
accounted for $3.4 million, $3.1 million, $2.7 million and $1.5 million, or 25%,
23%, 19% and 14%, of the Company's net revenues for the years ended December 31,
1992, 1993 and 1994 and the six months ended June 30, 1995, respectively. The
Company supplies a patented specialized tubing set used by M.D. Anderson
Hospital for oncology applications. While the Company believes its relations
with this customer are good, and while net revenues in percentage terms have
declined over time and are expected to decline further as a result of the
Neuromed Acquisition, the loss of this customer could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Risk Factors -- Reliance on Major Customer."
 
COMPETITION
 
     In marketing its products, the Company competes with numerous companies
that have substantially greater financial resources and engage in substantially
greater research and development efforts than the Company. Numerous competitors
exist for the Company's cardiovascular products, specialized tubing sets and
pressure monitoring kits. These markets are dominated by established
manufacturers that have broader product lines, greater distribution
capabilities, substantially greater capital resources and larger marketing,
research and development staffs and facilities than the Company. Many of these
competitors offer broader product lines within the specific product market
and/or in the general field of medical devices and supplies. Broad product lines
give many of the Company's competitors the ability to negotiate exclusive, long
term medical device supply contracts and, consequently, the ability to offer
comprehensive pricing of their competing products. By offering a broader product
line in the general field of medical devices and supplies, competitors may also
have a significant advantage in marketing competing products to group purchasing
organizations, HMOs and other managed care organizations that are increasingly
seeking to reduce costs through centralization of purchasing functions. In
addition, the Company's competitors may use price reductions to preserve market
share in their product markets. See "Risk Factors -- Intense Competition,
Continual Technological Change and New Surgical Techniques."
 
     The Company is aware of at least two cardioplegia delivery systems
currently in development or in clinical testing that would compete with the MPS
system. Both products have received FDA 510(k) market clearance. While these
products represent improvements over cardioplegia delivery systems currently in
use, the Company believes that the MPS system will offer a greater range of
functionality, flexibility and ease-of-use. In addition, innovations in surgical
techniques or medical practices could have the effect of reducing or eliminating
market demand for one or more of the Company's products. For example, some
cardiovascular surgeons and medical device companies are developing techniques,
procedures and devices for performing coronary artery bypass surgery without
stopping the heart, both through open-heart surgery and minimally invasive
procedures, thereby eliminating the need for myocardial protection in these
cases and potentially reducing the market for Quest's MPS system. While these
techniques, procedures and devices have not to date attained widespread use,
there can be no assurance that they will not gain broader market acceptance.
While these and other surgical techniques, procedures and devices may reduce the
number of coronary artery bypass procedures that require myocardial protection,
the Company believes that most, if not all, surgical suites will need to be
equipped with a myocardial protection system. See "Risk Factors -- Intense
Competition, Continual Technological Change and New Surgical Techniques."
 
     Neuromed competes in the market for SCS devices with one other significant
supplier, Medtronic, Inc. Medtronic holds a substantial majority share of the
market and sells both RF-coupled systems and IPG devices. See "-- Interventional
Pain Management -- Background."
 
     The Company believes that the principal competitive factors in the
cardiovascular, interventional pain management and intravenous fluid delivery
markets are cost-effectiveness, impact on patient outcomes, product performance,
quality and ease of use, technical innovation and customer service. The Company
intends to continue to compete on the basis of its high performance products,
innovative
 
                                       32
<PAGE>   33
 
technologies, manufacturing capability, close customer relations and support and
its strategy to increase its offerings of products within these markets.
 
PATENTS, TRADEMARKS AND PROPRIETARY RIGHTS
 
     The Company owns nineteen United States patents relating to products that
the Company currently sells or develops. Although one such patent is scheduled
to expire in February 1996 and another is scheduled to expire in January 1997,
the Company does not believe that either expiration will have a material adverse
effect on the Company or its ability to sell the applicable products. Twelve of
the nineteen patents cover the Company's cardiovascular products. From 1993
through 1995, the Company filed four applications for patents relating to the
MPS system and related products, one of which was issued in January 1995. The
issued patent contains 69 claims, many of which, in the Company's opinion,
contain broad coverage of key elements of the MPS system, including the MPS
system's innovative methods of pumping, mixing and heating fluids. Management
believes that the issued patent should provide significant protection for its
MPS system. The three other patent applications are pending.
 
     Neuromed currently owns four of the United States patents referred to
above, and also owns five foreign patents. In management's view, these patents
offer reasonable coverage of its SCS devices' electrode, receiver and
transmitter technology. These patents cover both RF-coupled devices and IPG
systems, although the Company currently manufactures only RF-coupled devices.
The Company is assessing whether it will file for patent protection concerning
its PainDoc product. The Company also owns three patents relating to its
intravenous fluid delivery tubing sets and accessories and other products.
 
     The validity of any patents issued to the Company may be challenged by
others and the Company could encounter legal and financial difficulties in
enforcing its patent rights against infringers. In addition, there can be no
assurance that other technologies cannot or will not be developed or that
patents will not be obtained by others which would render the Company's patents
obsolete. With the possible exception of the patent relating to the specialized
tubing sets manufactured for the University of Texas System Cancer Center (M.D.
Anderson Hospital), the loss of any one patent would not have a material adverse
effect on the Company's current revenue base. Although the Company does not
believe that patents are the sole determinant in the commercial success of its
products, the loss of a significant percentage of its patents or its patents
relating to a specific product line, particularly the MPS system or Neuromed's
SCS product line, could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     The Company has developed significant technical knowledge which, although
non-patentable, is considered by the Company to be significant in enabling it to
compete. However, the proprietary nature of such knowledge may be difficult to
protect. The Company has entered into an agreement with each key employee
prohibiting such employee from disclosing any confidential information or trade
secrets of the Company and prohibiting that employee from engaging in any
competitive business while the employee is working for the Company and for a
period of one year thereafter. In addition, these agreements also provide that
any inventions or discoveries relating to the business of the Company by these
individuals will be assigned to the Company and become the Company's sole
property.
 
     Claims by competitors and other third parties that the Company's products
allegedly infringe the patent rights of others could have a material adverse
effect on the Company. The medical device industry is characterized by frequent
and substantial intellectual property litigation. The cardiovascular device
market and the interventional pain management markets are maturing and, as such,
are characterized by extensive patent and other intellectual property claims,
which can create greater potential than in less developed markets for possible
allegations of infringement, particularly with respect to newly developed
technology. Intellectual property litigation is complex and expensive, and the
outcome of this litigation is difficult to predict. Any future litigation,
regardless of outcome, could
 
                                       33
<PAGE>   34
 
result in substantial expense to the Company and significant diversion of the
efforts of the Company's technical and management personnel. An adverse
determination in any such proceeding could subject the Company to significant
liabilities to third parties, or require the Company to seek licenses from third
parties or pay royalties that may be substantial. Furthermore, there can be no
assurance that necessary licenses would be available to the Company on
satisfactory terms or at all. Accordingly, an adverse determination in a
judicial or administrative proceeding or failure to obtain necessary licenses
could prevent the Company from manufacturing or selling certain of its products,
which could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Risk Factors -- Dependence on Patents
and Proprietary Rights."
 
     QUEST, MULTIPORT, RETROGUARD, RETRACT-O-TAPE, ACTest and DUO-TUBE are among
the Company's registered trademarks, and MPS, COMPUSTIM, PAINDOC and ACTester
are among its non-registered trademarks. Registration applications are pending
with respect to MPS, COMPUSTIM and PAINDOC.
 
GOVERNMENT REGULATION
 
     The manufacture and sale of the Company's products are subject to
regulation by numerous governmental authorities, principally the FDA and
corresponding foreign agencies. The research and development, manufacturing,
promotion, marketing and distribution of the Company's products in the United
States are governed by the Federal Food, Drug, and Cosmetic Act and the
regulations promulgated thereunder (the "FDC Act and Regulations"). The Company
is subject to inspection by the FDA for compliance with such regulations and
procedures.
 
     The FDA has traditionally pursued a rigorous enforcement program to ensure
that regulated entities such as the Company comply with the FDC Act and
Regulations. A company not in compliance may face a variety of regulatory
actions, including warning letters, product detentions, device alerts, mandatory
recalls or field corrections, product seizures, injunctive actions or civil
penalties and criminal prosecutions of the company or responsible employees,
officers and directors.
 
     Under the FDA's requirements, if a manufacturer can establish that a newly
developed device is "substantially equivalent" to a legally marketed device, the
manufacturer may seek marketing clearance from the FDA to market the device by
filing a 510(k) premarket notification with the FDA. The 510(k) premarket
notification must be supported by data establishing the claim of substantial
equivalence to the satisfaction of the FDA. The process of obtaining a 510(k)
clearance typically can take several months to a year or longer. If substantial
equivalence cannot be established, or if the FDA determines that the device
requires a more rigorous review, the FDA will require that the manufacturer
submit a PMA that must be carefully reviewed and approved by the FDA prior to
sale and marketing of the device in the United States. The process of obtaining
a PMA can be expensive, uncertain and lengthy, frequently requiring anywhere
from one to several or more years from the date of FDA submission. Both a 510(k)
and a PMA, if granted, may include significant limitations on the indicated uses
for which a product may be marketed. FDA enforcement policy strictly prohibits
the promotion of approved medical devices for unapproved uses. In addition,
product approvals can be withdrawn for failure to comply with regulatory
requirements or the occurrence of unforeseen problems following initial
marketing. Although all of the Company's currently marketed products have been
the subject of successful 510(k) submissions, and the Company believes that its
products currently in development will also be eligible for the 510(k)
submission process, there can be no assurance that the FDA will agree with this
view.
 
     In the second quarter of 1994, the Company held a pre-submission meeting
with the FDA's Office of Device Evaluation to determine whether the MPS system
qualified for a 510(k) filing. Based on its meeting with the FDA, the Company
concluded that the MPS system would qualify for 510(k) treatment, and opted to
file its application with test data to facilitate the FDA's review. After
compiling test data over the course of 1995, the Company filed its 510(k)
notification in August 1995. The Company expects to introduce MPS and related
products to commercial markets if and when the FDA
 
                                       34
<PAGE>   35
 
clears MPS to market. There can be no assurance that the FDA will consider the
MPS system under 510(k), that such clearance will be obtained or that it will be
obtained without delay. See "Risk Factors -- Government Regulation; Uncertainty
of Obtaining Regulatory Clearance."
 
     The Company's PainDoc product has been marketed as a data recording and
programming device for use with the Company's CompuStim devices. In October
1995, the Company received 510(k) clearance from the FDA to market PainDoc as an
interactive medical treatment device as well. As a data recording and
programming device, PainDoc can be used to record important information
regarding the location and intensity of a patient's pain, analyze that data, and
automate the selection of a large number of electrode arrays that would be
difficult to select manually. PainDoc is then used to program the most
efficacious electrode arrays to alleviate the patient's pain. As an interactive
medical treatment device, this data collection, analysis, selection and
programming process can be accomplished while the patient is receiving
neurostimulation, where before, the transmitter had to be disconnected during
the analysis and programming phase. The Company believes that as an interactive
medical treatment device, PainDoc's value is enhanced because the physician can
accelerate the treatment process through "live" testing.
 
     The Company is also subject to regulation in each of the foreign countries
in which it sells its products with regard to product standards, packaging
requirements, labeling requirements, import restrictions, tariff regulations,
duties and tax requirements. Many of the regulations applicable to the Company's
products in such countries are similar to those of the FDA. The national health
or social security organizations of certain countries require the Company's
products to be qualified before they can be marketed in those countries. To
date, the Company has not experienced significant difficulty in complying with
these regulations.
 
     To position itself for access to European and other international markets,
Quest sought and obtained certification under the ISO 9000 Series of Standards.
ISO 9000 is a set of integrated requirements, which when implemented, form the
foundation and framework for an effective quality management system. These
standards were developed and published by the ISO, a worldwide federation of
national standard bodies, founded in Geneva, Switzerland in 1946. ISO has over
92 member countries. ISO certification is widely regarded as essential to enter
Western European markets.
 
     The Company obtained certification and was registered as an ISO 9001
compliant company on July 1, 1995. The ISO 9001 registration is the most
stringent standard in the ISO series and lasts for three years. The German
notified body, Landesgewerbeanstalt Bayern ("LGA") issued the certificate. The
ISO 9001 standards cover design, production, installation and servicing of
products. The Company will be subject to an annual audit by LGA to maintain the
registration. This registration will simplify the process of obtaining the "CE"
mark for its products. This CE mark enables a company's products to be marketed,
sold and used throughout the European Union.
 
     In 1991, prior to its acquisition by the Company, Neuromed commenced
clinical trials of a fully implantable SCS device in the United States and
Europe. In late 1993, the FDA cancelled the IDE relating to this product and
rescinded Neuromed's export authority for this product due to alleged violations
by Neuromed, under its prior management, of applicable rules and regulations,
including good manufacturing practices. The clinical trials were discontinued
and the product was withdrawn from the market. During this period, Neuromed also
encountered regulatory difficulties in the United Kingdom due to alleged
noncompliance with applicable rules and regulations. Quest is engaged in a
process intended to restore good relations with regulatory authorities in the
United Kingdom. There can be no assurances that the Company will not encounter
similar difficulties in the future.
 
     The financial arrangements through which the Company markets, sells and
distributes its products may be subject to certain federal and state laws and
regulations in the United States with respect to the provision of services or
products to patients who are Medicare or Medicaid beneficiaries. The "fraud and
abuse" laws and regulations prohibit the knowing and willful offer, payment or
receipt of anything of value to induce the referral of Medicare or Medicaid
patients for services or goods. In addition, the physician anti-referral laws
prohibit the referral of Medicare or Medicaid patients for certain "Desig-
 
                                       35
<PAGE>   36
 
nated Health Services" to entities in which the referring physician has an
ownership or compensation interest. Violations of these laws and regulations may
result in civil and criminal penalties, including substantial fines and
imprisonment. In a number of states, the scope of fraud and abuse or physician
anti-referral laws and regulations, or both, have been extended to include the
provision of services or products to all patients, regardless of the source of
payment, although there is variation from state to state as to the exact
provisions of such laws or regulations. In other states, and, on a national
level, several health care reform initiatives have been proposed which would
have a similar impact. The Company believes that its operations and its
marketing, sales and distribution practices currently comply in all respects
with all current fraud and abuse and physician anti-referral laws and
regulations, to the extent they are applicable. Although the Company does not
believe that it will need to undertake any significant expense or modification
to its operations or its marketing, sales and distribution practices to comply
with federal and state fraud and abuse and physician anti-referral regulations
currently in effect or proposed, financial arrangements between manufacturers of
medical devices and other health care providers may be subject to increasing
regulation in the future. Compliance with such regulation could adversely affect
the Company's marketing, sales and distribution practices, and may affect the
Company in other respects not presently foreseeable, but which could have an
adverse impact on the Company's business, financial condition and results of
operations.
 
THIRD PARTY REIMBURSEMENT AND COST CONTAINMENT
 
     The Company's products are purchased primarily by hospitals and other
users, which then bill various third party payors for the services provided to
the patients. These payors, which include Medicare, Medicaid, private insurance
companies and managed care organizations, reimburse part or all of the costs and
fees associated with the procedures performed with these devices.
 
     Medicare and Medicaid reimbursement for hospitals is based on a fixed
amount for admitting a patient with a specific diagnosis. Because of this fixed
reimbursement method, hospitals have incentives to use less costly methods in
treating Medicare and Medicaid patients, and will frequently make capital
expenditures to take advantage of less costly treatment technologies.
Frequently, reimbursement is reduced to reflect the availability of a new
procedure or technique, and as a result hospitals are generally willing to
implement new cost saving technologies before these downward adjustments take
effect. Likewise, because the rate of reimbursement for certain physicians who
perform certain procedures has been and may in the future be reduced in the
event of further changes in the resource-based relative value scale method of
payment calculation, physicians may seek greater cost efficiency in treatment to
minimize any negative impact of reduced reimbursement. Any amendments to
existing reimbursement rules and regulations which restrict or terminate the
reimbursement eligibility (or the extent or amount of coverage) of medical
procedures using the Company's products or the eligibility (or the extent or
amount of coverage) of the Company's products could have an adverse impact on
the Company's business, financial condition and results of operations. Third
party payors are increasingly challenging the prices charged for medical
products and services and may deny reimbursement if they determine that a device
was not used in accordance with cost-effective treatment methods as determined
by the payor, was experimental or was used for an unapproved application.
 
     The Company's SCS devices, for example, while cost-effective compared to
repeat back surgeries, have encountered some resistance to third party
reimbursement. Although Medicare, Medicaid and many private insurers reimburse
for the SCS device and procedure, especially after repeat back surgeries have
failed to relieve the chronic pain, certain payors refuse to reimburse for SCS
devices and others, including the Veterans Administration, restrict
reimbursement. There can be no assurance that in the future, third party payors
will continue to reimburse for the Company's products, or that their
reimbursement levels will not adversely affect the profitability of the
Company's products. In addition, the cost of health care has risen significantly
over the past decade, and there have been and may continue to be proposals by
legislators and regulators to curb these costs. Legislative action limiting
reimbursement for certain procedures could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
                                       36
<PAGE>   37
 
     In response to the focus of national attention on rising health care costs,
a number of changes to reduce costs have been proposed or have begun to emerge.
There have been, and may continue to be, proposals by legislators and regulators
and third party payors to curb these costs. There has also been a significant
increase in the number of Americans enrolling in some form of managed care plan.
It has become a typical practice for hospitals to affiliate themselves with as
many managed care plans as possible. Higher managed care penetration typically
drives down the prices of health care procedures, which in turn places pressure
on medical supply prices. This causes hospitals to implement tighter vendor
selection and certification processes, by reducing the number of vendors used,
purchasing more products from fewer vendors and trading discounts on price for
guaranteed higher volumes to vendors. Hospitals have also sought to control and
reduce costs over the last decade by joining group purchasing organizations or
purchasing alliances. The Company cannot predict what continuing or future
impact existing or proposed legislation, regulation or such third party payor
measures may have on its future business, financial condition or results of
operations.
 
     Changes in reimbursement policies and practices of third party payors could
have a substantial and material impact on sales of certain of the Company's
products. The development or increased use of more cost-effective treatments
could cause such payors to decrease or deny reimbursement to favor these other
treatments. See "Risk Factors -- Cost Pressures on Medical Technology; Third
Party Reimbursement."
 
EMPLOYEES
 
     As of November 6, 1995, the Company employed approximately 214 full-time
employees, 22 in research and development, 30 in sales and marketing, 120 in
manufacturing and related operations, and the remainder in executive and
administrative positions. The Neuromed Acquisition has added 56 of these
employees to the existing employee base. None of the Company's employees is
represented by a labor union, and the Company considers its employee relations
to be good.
 
ADVISORY BOARD
 
     The Company has established a Board of Clinical Advisors (the "Advisory
Board") comprised of individuals with substantial expertise in the field of
myocardial protection who have played instrumental roles in the identification
of the market need for the MPS system and its subsequent design and development.
Members of the Company's management and scientific and technical staff consult
closely with the Advisory Board to better understand the technical and clinical
requirements of the cardiovascular surgical team and product functionality
needed to meet those requirements. The Company anticipates that these Advisory
Board members will continue to play similar roles with respect to other
products, and may assist the Company in educating other physicians in the use of
the MPS system and related products.
 
     Certain members of the Advisory Board are employed by academic institutions
and may have commitments to or consulting or advisory agreements with other
entities that may limit their availability to the Company. The members of the
Advisory Board may also serve as consultants to other medical device companies.
No members are expected to devote more than a small portion of their time to the
Company.
 
FACILITIES
 
     In December 1993, the Company moved into its new manufacturing facility and
executive offices in Allen, Texas (located north of Dallas). The facility covers
approximately 107,000 square feet and was constructed during 1993 on a 19.2 acre
tract that the Company acquired in 1985. The Company borrowed $4.4 million from
MetLife Capital Corporation to construct and outfit this facility. This
financing is collateralized by the Allen land, the Allen facility and certain
equipment of the Company. See Note 3 of the Notes to the Quest Consolidated
Financial Statements. Management expects the
 
                                       37
<PAGE>   38
 
current facility to serve its manufacturing, storage and executive office needs
in the Dallas area for the foreseeable future.
 
     The Company also currently leases approximately 4,600 square feet of office
and manufacturing space in Orange County, California on a month-to-month basis.
The Company plans to continue manufacturing certain cardiovascular surgery
products at this facility for the foreseeable future.
 
     Neuromed leases approximately 18,000 square feet of office and
manufacturing space in Fort Lauderdale, Florida, where it manufactures and
markets its SCS devices. The Company plans to transition the SCS manufacturing
and marketing functions to its headquarters in Allen by the end of the first
quarter of 1996. Pending this move, the Company believes this facility will
serve Neuromed's needs.
 
LEGAL PROCEEDINGS
 
     As a consequence of the Neuromed Acquisition in March 1995, the Company is
currently a party to certain product liability claims relating to SCS devices
sold by Neuromed prior to the acquisition, including one claim relating to a
fully implantable device, which was recalled by Neuromed. Product liability
insurers have assumed responsibility for defending the Company against these
claims, subject to reservation of rights in certain cases. Although the Company
is entitled to contractual indemnification from Neuromed's former owner with
respect to any losses exceeding its product liability insurance coverage, there
can be no assurances that the Company will not incur significant monetary
liability to the claimants if such insurance or indemnification is unavailable
or inadequate for any reason, or that the Company's SCS business and new SCS
product lines will not be adversely affected by these product liability claims.
While the Company seeks to maintain appropriate levels of product liability
insurance with coverage that the Company believes is comparable to that
maintained by companies similar in size and serving similar markets, there can
be no assurance that the Company will avoid significant future product liability
claims relating to its SCS, cardiovascular, intravenous fluid delivery or other
products. See "Risk Factors -- Potential Product Liability and Recall; Possible
Insurance Limitations" and "-- Government Regulation."
 
     Except for such product liability claims and other ordinary routine
litigation incidental or immaterial to its business, the Company is not
currently a party to any other pending legal proceeding. The Company maintains
general liability insurance against risks arising out of the normal course of
business.

BENEFIT PLANS AND OTHER ARRANGEMENTS
 
     1979 Stock Option Plan. Pursuant to the 1979 Stock Option Plan, officers
and other employees of the Company may receive options to purchase shares of
Common Stock. The 1979 Stock Option Plan was approved by the Board in 1979 and
amended and approved by the shareholders in 1992. The 1979 Stock Option Plan
provides for the grant of both incentive stock options intended to qualify for
preferential tax treatment under Section 422 of the Internal Revenue Code of
1986, as amended, and nonqualified stock options that do not qualify for this
treatment. The exercise price of all options granted under the 1979 Stock Option
Plan must equal or exceed the fair market value of the Common Stock at the time
of grant. The 1979 Stock Option Plan is administered by the Stock Option
Committee.
 
     A total of 1,019,867 shares of Common Stock has been reserved for issuance
under the 1979 Stock Option Plan. As of November 6, 1995, there were outstanding
options to purchase an aggregate of 570,022 shares, at a weighted average
exercise price of $3.36 per share, pursuant to the 1979 Stock Option Plan. Only
7,705 shares of Common Stock remain available under the 1979 Stock Option Plan
for the grant of additional non-qualified stock options. (A total of 442,140
shares had previously been issued upon the exercise of stock options granted
under the plan.)
 
     1987 Stock Option Plan. On December 22, 1987, the Board of Directors
approved the 1987 Stock Option Plan. Pursuant to the 1987 Stock Option Plan,
certain officers of the Company received options to purchase shares of Common
Stock. The 1987 Stock Option Plan provides for the grant of nonqualified stock
options that do not qualify for preferential tax treatment under Section 422 of
the Internal Revenue Code of 1986, as amended. The exercise price of all options
granted under the 1987 Stock Option Plan must equal or exceed the fair market
value of the Common Stock at the time of grant. The 1987 Stock Option Plan is
administered by the disinterested members of the Board of Directors.
 
     A total of 302,910 shares of Common Stock has been reserved for issuance
under the 1987 Stock Option Plan. As of November 6, 1995, there were outstanding
options to purchase an aggregate of 95,910 shares, at a weighted average
exercise price of $1.45 per share pursuant to the 1987 Stock Option Plan. No
shares of Common Stock remain available under the 1987 Stock Option Plan for the
grant of additional stock options. (A total of 207,000 shares have been
previously issued upon the exercise of stock options granted under the plan.)
 
     1995 Stock Option Plan. On March 30, 1995 and June 22, 1995, respectively,
the Board of Directors and shareholders of the Company approved the 1995 Stock
Option Plan. Pursuant to the 1995 Stock Option Plan, officers or other employees
of the Company or any of its subsidiaries (including Neuromed) are eligible to
receive stock option grants under the 1995 Stock Option Plan. The 1995 Stock
Option Plan provides for the grant of both incentive stock options intended to
qualify for preferential tax treatment under Section 422 of the Internal Revenue
Code of 1986, as amended, and nonqualified stock options that do not qualify for
this treatment. The exercise price of all options granted under the 1995 Stock
Option Plan must equal or exceed the fair market value of the Common Stock at
the time of grant. The 1995 Stock Option Plan is administered by the Stock
Option Committee.
 
     A total of 250,000 shares of Common Stock has been reserved for issuance
under the 1995 Stock Option Plan; provided, however, that on January 1 of each
year (commencing on January 1, 1996), the aggregate number of shares of Common
Stock reserved for issuance under the Plan shall be increased by the same
percentage that the total number of issued and outstanding shares of Common
Stock increased from the preceding January 1 to the following December 31 (if
such percentage is positive). As of November 6, 1995, the Company had
outstanding options under the 1995 Stock Option Plan to purchase an aggregate of
207,000 shares, at a weighted average exercise price of $8.09 per share,
pursuant to the 1995 Stock Option Plan.
 
     Directors' Plan. The Quest Medical, Inc. Directors' Stock Option Plan (the
"Directors' Plan") provides for grants of nonqualified stock options, which are
nontransferable, to purchase shares of Common Stock to directors and members of
the Advisory Board of the Company. Options granted
 
                                       42
<PAGE>   43
 
under the Directors' Plan vest ratably over a four-year period and the exercise
period for such options cannot exceed six years. Under the Directors' Plan, the
option price per share cannot be less than the fair market value per share on
the date the option is granted. The Company has reserved 557,635 shares of
Common Stock for issuance under the Directors' Plan. As of November 6, 1995, the
Company had outstanding options to purchase an aggregate of 239,716 shares, at a
weighted average exercise price of $3.74 per share pursuant to the Directors'
Plan. Only 67,750 shares of Common Stock remain available under the Directors'
Plan for the grant of additional stock options. (A total of 250,169 shares have
been previously issued upon exercise of stock options granted under the plan.)
The Directors' Plan is administered by the Stock Option Committee.
 
     During the year ended December 31, 1994, two directors were granted options
under the Directors' Plan. Robert C. Eberhart, Ph.D. was granted options to
purchase 15,450 shares of Common Stock at an exercise price of $4.245 and
Michael J. Torma, M.D. was granted options to purchase 15,000 shares of Common
Stock at an exercise price of $6.375. During the year ended December 31, 1994,
no options were exercised under the Directors' Plan; however, during April 1995,
two directors exercised options which were scheduled to expire during May and
August 1995. Linton E. Barbee purchased 15,450 shares of Common Stock at an
exercise price of $2.18. The net value of such securities to Mr. Barbee at the
time of exercise (market value less exercise price) was $78,331. Hugh M.
Morrison purchased 6,180 shares of Common Stock at an exercise price of $1.45.
The net value of such securities to Mr. Morrison was $38,161. In June 1995,
Michael J. Torma, M.D. exercised options to purchase 3,750 shares of Common
Stock at an exercise price of $6.375. The net value of such securities to Dr.

of $3.92 per share under the Directors' Plan to the members of the Advisory
Board. Certain members of the Advisory Board also provide consulting services to
the Company for which they are compensated through separate agreements.
 
     Employees Savings Plan. The Company has established a Employees Savings
Plan (the "Savings Plan"), which is qualified under Sections 401(a) and 401(k)
of the Code, pursuant to which all full-time employees of the Company may elect
to have the Company make certain salary reduction contributions on their behalf.
Under the Savings Plan, with certain limited exceptions, an employee may elect
to contribute up to 15% of his total compensation to the plan on a pre-tax
basis, and requires the Company to make matching contributions equal to 50% of a
participant's salary deferral, to a maximum of salary deferral contributions
equal to 6% of the participant's total cash compensation, up to $150,000. The
amount of the matching employer contribution may be increased or decreased at
the discretion of the Board of Directors. During the year ended December 31,
1994, the Company committed to contribute approximately $102,961 to the Savings
Plan.
 
INDEMNIFICATION AND LIMITATION OF LIABILITY
 
     The Company's Articles of Incorporation include a provision eliminating or
limiting director liability to the Company and its shareholders for monetary
damages arising from acts or omissions in the director's capacity as a director.
Consistent with the Texas Business Corporation Act, the Company's Articles of
Incorporation do not eliminate or limit a director's liability to the extent the
director is found liable for (i) a breach of the director's duty of loyalty to
the Company or its shareholders, (ii) an act or omission not in good faith that
constitutes a breach of duty of the director to the Company or an act or
omission that involves intentional misconduct or a knowing violation of the law,
(iii) a transaction from which the director received an improper benefit,
whether or not the benefit resulted from an action taken within the scope of the
director's office, (iv) an act or omission for which the liability of a director
is expressly provided by an applicable statute, or (v) an act related to an
unlawful stock repurchase or payment of a dividend.

     In addition, the Company maintains insurance on behalf of its directors and
executive officers insuring them against any liability asserted against them in
their capacities as directors or officers or arising out of such status.
 
DIRECTORS' COMPENSATION
 
     Non-management directors receive $1,000 for each Board of Directors meeting

                              CERTAIN TRANSACTIONS
 
     On March 31, 1995, the Company acquired all of the issued and outstanding
capital stock of Neuromed, which was held by Mr. William Borkan and his brother,
Mr. Burt Borkan. The Neuromed Acquisition has been accounted for as a purchase.
The Company paid the Borkans $15.4 million in cash ($200,000 of which was paid
in June 1995 as a purchase price adjustment) and issued them 833,333 shares of
Common Stock valued at $6.5 million. Depending on Neuromed's attainment of
certain sales objectives, the Company agreed to pay the Borkans' contingent
"earn-out" consideration in January 1996 and January 1997, payable in a
combination of cash and Common Stock. The Company and Mr. William Borkan also
entered into a consulting agreement pursuant to which Mr. Borkan agreed to
provide certain consulting services to the Company at the rate of $1,000 per
day. The Company is required to pay Mr. Borkan for a minimum of five days per
month ($5,000) until October 31, 1995 and two days per month ($2,000) thereafter
until October 31, 1996. In June 1995, Mr. William Borkan was elected to the
Company's Board of Directors.
 
     In September 1995, the Company and Mr. William Borkan amended certain terms
of the Neuromed acquisition agreement. Under the amendment, (i) the Company
agreed to issue Mr. Borkan 200,000 additional shares of Common Stock
concurrently with the closing of the Offering and pay Mr. Borkan $1.5 million in
cash in January 1996 to satisfy the 1996 contingent payment obligation, which
had been earned in July 1995, (ii) the Company agreed to include all of the
Borkans' Common Stock (1,033,333 shares) in this Offering, (iii) Mr. Borkan
resigned from the Company's Board of Directors and relinquished his board
representation and attendance rights, (iv) Mr. Borkan relinquished his
registration rights, and (v) in the event the 1997 contingent earn-out payment
is fully earned, the Company agreed to pay Mr. Borkan an amount in cash equal to
$1.5 million plus the value of 200,000 shares of Common Stock at the net
Offering price. In the event the Offering is not consummated, among other
things, Mr. Borkan will regain his board representation and attendance rights
and his registration rights.
 
     The Company has engaged the services of the law firm Fulbright & Jaworski,
L.L.P. located in Dallas, Texas. Mr. Linton E. Barbee, a director of the
Company, is a partner of such firm.

director options, of which options to purchase 1,168,548 shares have been
granted at exercise prices ranging from $1.45 to $12.13 per share. See
"Management -- Benefits Plans and Other Arrangements." The Company will hold
355,571 shares in its treasury following the Offering.
 
     Holders of Common Stock are entitled to receive such dividends, if any, as
may be declared by the Board of Directors out of legally available funds. In the
event of the liquidation, dissolution or winding up of the Company, holders of
Common Stock are entitled to share equally and ratably, based on the number of
shares held, in the assets, if any, remaining after payment of all of the
Company's debts and liabilities.
 
     Holders of Common Stock are entitled to one vote per share for each share
held of record on any matter submitted to the holders of Common Stock for a
vote. Because holders of Common Stock do not have cumulative voting rights, the
holders of a majority of the shares of Common Stock represented at a meeting can
elect all the directors. Holders of Common Stock do not have preemptive rights
to subscribe for or purchase any additional shares of capital stock issued by
the Company. All outstanding shares of the Common Stock are, and the shares of
Common Stock offered hereby will be when issued, duly authorized, validly
issued, fully paid and nonassessable.
 
TRANSFER AGENT AND REGISTRAR
 
     KeyCorp Shareholder Services, Inc. is the transfer agent and registrar for
the Common Stock.
 
SHAREHOLDERS' RIGHTS PLAN
 
     The Company has a Shareholders' Rights Plan that may make the acquisition
of control of the Company by means of tender offer, open market purchase, proxy
contest or otherwise more difficult.
 
                                       46

     Each share of Common Stock has associated with it one Common Stock purchase
right ("Right") to purchase from the Company one-half a share of Common Stock at
a price of $12.50 (the "Purchase Price"), subject to adjustment. The description
of and terms of the Rights are set forth in a Rights Agreement dated October 12,
1989 between the Company and MTrust Corp., N.A., as amended by that Amendment of
Rights Agreement dated as of February 9, 1995 (as amended, the "Rights
Agreement"), between the Company and KeyCorp Shareholder Services, Inc. (the
"Rights Agent"). Until the earlier to occur of: (i) 10 days following a public
announcement that a person or group of affiliated or associated persons has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding shares of Common Stock, except the Company, any subsidiary of
the Company, any employee benefit plan of the Company or William Borkan so long
as Mr. Borkan's beneficial ownership does not exceed 25% of the Common Stock
outstanding or any person who acquires beneficial ownership in a Permitted
Transaction or a Qualified Offer (an "Acquiring Person"); or (ii) 10 days (or
such later date as may be determined by action of the Board of Directors prior
to any person becoming an Acquiring Person) following the commencement of, or
announcement of an intention to make, a tender offer or exchange offer, the
consummation of which would result in the beneficial ownership by a person or
group of 20% or more of such outstanding shares of Common Stock (the earlier of
such dates being the "Distribution Date"), the Rights are evidenced by the
Common Stock certificates.
 
     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Stock. Until the Distribution
Date (or earlier redemption or expiration of the Rights), new Common Stock
certificates issued upon transfer or new issuance of Common Stock will contain
the notation incorporating the Rights Agreement by reference. As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights (the "Rights Certificates") will be mailed to holders of record of
the Common Stock as of the close of business on the Distribution Date and such
separate Right Certificates alone will evidence the Rights. The Rights are not
exercisable until the Distribution Date and will expire on October 12, 1999 (the
"Final Expiration Date"), unless extended or unless the Rights are earlier
redeemed by the Company.
 
     The Purchase Price payable and the number of shares of Common Stock or
other securities or property issuable upon exercise of the Rights are subject to
adjustment in certain circumstances. In the event any person or entity becomes
an Acquiring Person and one of the following events have occurred, then proper
provision will be made so that each holder of a right, other than Rights
beneficially owned by the Acquiring Person (which will then be void), will have
the right to receive upon exercise that number of shares of Common Stock having
a market value of two times the applicable exercise price of the Right: (i) the
Company is the surviving corporation in a merger with an Acquiring Person and
the Common Stock is not changed or exchanged; (ii) the Acquiring Person engages
in certain self-dealing transactions with the Company; (iii) any person becomes
the beneficial owner of 20% or more of the outstanding shares of Common Stock
(unless the event in which such person acquired 20% or more of the outstanding
shares of Common Stock is a Permitted Transaction or pursuant to a Qualifying
Offer, each of which is defined below); or (iv) the Company engages in a
reclassification or recapitalization that results in an increase of 1% or more
in the Acquiring Person's percentage of ownership of the Company.
 
     A Permitted Transaction is a stock acquisition or tender or exchange offer
pursuant to a definitive agreement which would result in a person beneficially
owning 50% or more of the Common Stock and which was approved by the Directors
(including a majority of the Directors not in association with an Acquiring
Person) prior to the execution of the Agreement or the public announcement of
the offer. A Qualifying Offer is defined as: an all-cash tender offer for 100%
of the outstanding securities of the Company; includes a commitment to pay cash
consideration at least equal to the highest per share consideration paid by the
tender offeror for the Company's securities within the previous 12-month period;
includes the tender offeror's undertaking to complete a second-step, "clean up"
merger in which the tender offeror will pay the same cash consideration as in
the tender offer; and results in the acquisition of a majority of the
outstanding securities of the Company. In the event that the Company is acquired
in a merger or other business combination transaction or 50% or more if its
consolidated
 
                                       47
<PAGE>   48
 
assets or earning power are sold, unless such event is a Permitted Transaction
or pursuant to a Qualifying Offer, proper provisions will be made so that each
holder of a Right will have the right to receive, upon the exercise of the Right
at the then applicable exercise price, that number of shares of common stock of
the acquiring company that at the time of such transaction will have a market
value of two times the applicable exercise price of the Right. At any time prior
to the tenth day following an Acquiring Person's acquisition of 15% or more of
the outstanding Common Stock, the Board of Directors of the Company, with
concurrence of a majority of the directors in office at the time the Rights
Agreement was adopted or whose initial election or nomination for election by
the Company's shareholders was approved by a majority of the Continuing
Directors then serving on the Board of Directors (the "Continuing Directors"),
may redeem the Rights in whole, but not in part, at a price of $0.01 per Right.
In addition, the Board of Directors may extend or reduce the period during which
the Rights are redeemable, so long as the Rights are redeemable at the time of
such extension or reduction. Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price. The terms of the Rights may be
amended by the Board of Directors of the Company, with concurrence of a majority
of the Continuing Directors, without the consent of the holders of the Rights,
including an amendment to extend the Final Expiration Date, except that from and
after the Distribution Date no such amendment may adversely affect the economic
interests of the holders of the Rights.

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent, including the absence
of any material adverse change in the Company's business and the receipt of
certain certificates, opinions and letters from the Company, the Selling
Shareholders and their respective counsel. The nature of the Underwriters'
obligation is such that they
 
                                       48
<PAGE>   49
 
are committed to purchase all shares of Common Stock offered hereby if any of
such shares are purchased. The Underwriting Agreement contains certain
provisions whereby if any Underwriter defaults in its obligation to purchase
shares, and the aggregate obligations of the Underwriters so defaulting do not
exceed 10% of the shares offered hereby, the remaining Underwriters, or some of
them, must assume such obligations.
 
     The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock directly to the public at the public
offering price set forth on the cover of this Prospectus, and to certain dealers
at such price less a concession not in excess of $0.39 per share. The
Underwriters may allow, and such dealers may reallow, a concession not in excess
of $0.10 per share to certain other dealers. After the public offering of the
shares of Common Stock, the offering price and other selling terms may be
changed by the Underwriters.
 
     The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to 360,000
additional shares of Common Stock to cover over-allotments, if any, at the
public offering price, less underwriting discounts and commissions, set forth on
the cover page of this Prospectus. To the extent that the Underwriters exercise
this option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage thereof which the number of shares of Common
Stock to be purchased by it shown in the above table bears to the total number
of shares of Common Stock offered hereby. The Company will be obligated,
pursuant to the option, to sell such shares to the Underwriters to the extent
the option is exercised. If purchased, the Underwriters shall offer such
additional shares on the same terms as those on which the shares are being
offered hereby.
 
     The offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the Offering without notice. The Underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the "Securities Act") and to contribute to
payments the Underwriters may be required to make in respect thereof.
 
     The executive officers, directors, and certain other employees and
shareholders of the Company have agreed that they will not, without the prior
written consent of the Representatives, offer, sell or otherwise dispose of any
shares of Common Stock, options or warrants to acquire shares of Common Stock or
securities exchangeable for or convertible into shares of Common Stock owned by
them for a period of 120 days after the date of this Prospectus. The Company has
agreed that it will not, without the prior written consent of the
Representatives, offer, sell or otherwise dispose of any shares of Common Stock,
options or warrants to acquire shares of Common Stock or securities exchangeable
for or convertible into shares of Common Stock for a period of 120 days after
the date of this Prospectus, except that the Company may grant additional
options under its stock option plans, or issue shares upon the exercise of
outstanding stock options.
 
     In connection with this offering certain Underwriters and selling group
members (if any) who are qualifying registered market makers on the Nasdaq
National Market may engage in passive market-making transactions in the Common
Stock on the Nasdaq National Market in accordance with Rule 10b-6A under the
Securities Exchange Act of 1934 during the two business day period before
commencement of sales in this offering. The passive market making transactions
must comply with applicable volume and price limits and be identified as such.
In general, a passive market maker may display its bid at a price not in excess
of the highest independent bid for the security. If all independent bids are
lowered below the passive market maker's bid, however, such bid must then be
lowered when certain purchase limits are exceeded. Net purchases by a passive
market maker on each day are generally limited to a specified percentage of the
passive market making average daily trading volume in the Common Stock during a
price period and must be discontinued when such limit is reached. Passive market
making may stabilize the market price of the Common Stock at a level above that
which might otherwise prevail, and, if commenced, may be discontinued at any
time.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Quest Medical, Inc.
 
     We have audited the accompanying consolidated balance sheets of Quest
Medical, Inc. and subsidiaries (the Company) as of December 31, 1993 and 1994,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended December 31, 1994.
These consolidated 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 consolidated financial position of Quest Medical,
Inc. and subsidiaries at December 31, 1993 and 1994, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1994, in conformity with generally accepted
accounting principles.
 
     As discussed in Note 1 to the financial statements, in 1993 the Company
changed its method of accounting for certain investments in debt and equity
securities.

  (d) Marketable Securities
 
     Effective December 31, 1993, the Company's marketable equity securities and
debt securities are classified as available-for-sale. Available-for-sale
securities are carried at fair value, with the unrealized gains and losses
reported in a separate component of stockholders' equity. The amortized cost of
debt securities in this category is adjusted for amortization of premiums and
accretion of discounts to maturity. Such amortization is included in investment
income. Realized gains and losses and declines in value judged to be
other-than-temporary are included in other income. The cost of securities sold
is based on the specific identification method. Interest and dividends on
securities classified as available-for-sale are included in investment income.
Prior to December 31, 1993, marketable securities were accounted for at the
lower of cost or market.

1994:

     At June 30, 1995, no individual security represented more than 10% of the
total portfolio or 1% of total assets. The Company did not have any investments
in derivative financial instruments at June 30, 1995.
 
  (e) Inventories
 
     Inventories are recorded at the lower of standard cost or market. Standard
cost approximates actual cost determined on the first-in, first-out (FIFO)
basis.
 
  (f) Property, Plant and Equipment
 
     Property, plant and equipment are stated at cost. Major renewals and
betterments are capitalized; maintenance and repairs are charged to operations
as incurred. The cost and accumulated depreciation of assets retired are removed
from the accounts.
 
     Provisions for depreciation and amortization of property, plant and
equipment are computed using the straight-line method using estimated useful
lives of 3 to 30 years.
 
     During 1993, the Company constructed a new corporate headquarters and
production facility for its operations in Allen, Texas (the "Allen facility").
The Company's Dallas operations were relocated to such facility during December
1993.
 
  (g) Costs in Excess of Net Assets Acquired
 
     The excess of costs over the net assets of businesses acquired is amortized
on a straight line basis over estimated useful lives of 20 to 25 years. The
Company assesses the recoverability of this intangible asset, as well as other
intangible assets, primarily based on its current and anticipated future
undiscounted cash flows. At December 31, 1994 and June 30, 1995, the Company
does not believe there has been any impairment of its intangible assets.
Amortization expense was $20,806, $30,854 and $40,753 for the years ended
December 31, 1992, 1993, and 1994, respectively. Amortization expense was
$19,387 and $59,809 for the six months ended June 30, 1994 and 1995,
respectively.
 
  (h) Patents
 
     Cost of purchased patents is amortized on a straight-line basis over the
estimated useful lives (4 to 14 years) of such patents. Amortization expense was
$188,854, $228,852, and $228,467 for the years ended December 31, 1992, 1993,
and 1994, respectively. Amortization expense was $114,234 for each of

the six month periods ended June 30, 1994 and 1995. The cost and accumulated
amortization of fully amortized patents are removed from the accounts.
 
     Costs of patents which are the result of internal development are charged
to current operations.
 
  (i) Purchased Technology Related to Acquisitions
 
     The cost of purchased technology related to acquisitions is based on
appraised values at the date of acquisition and is amortized on a straight-line
basis over the estimated useful lives (10 to 15 years) of such technology.
Amortization expense was $154,897, $50,551, and $50,550 for the years ended
December 31, 1992, 1993, and 1994, respectively. Amortization expense was
$25,275 and $91,943 for the six months ended June 30, 1994 and 1995,
respectively.
 
  (j) Tradenames
 
     The cost of purchased tradenames is based on appraised values at the date
of acquisition and is amortized on a straight-line basis over the estimated
useful life (20 years) of such tradenames. No amortization expense was recorded
during the years ended December 31, 1992, 1993, 1994 or the six months ended
June 30, 1994. Amortization expense was $31,250 for the six months ended June
30, 1995.
 
  (k) Product Development
 
     Start-up, research and development, advertising and promotional costs are
charged to operations in the year in which such costs are incurred.
 
  (l) Earnings per Common and Common Equivalent Share
 
     During April 1994, the Board of Directors approved a 3% stock dividend. The
distribution date was May 23, 1994, for shareholders of record as of May 6,
1994. The weighted average number of common and common equivalent shares
outstanding used in computing the earnings per share for the years ended
December 31, 1993 and 1992 were increased to retroactively reflect the stock
dividend.
 
     Earnings (loss) per share for the years ended December 31, 1992, 1993, and
1994 are based upon 5,594,141, 5,559,422 and 5,256,683 common and, in 1992 and
1993, common equivalent shares outstanding, respectively. Shares issuable upon
exercise of dilutive stock options are included in average common and common
equivalent shares outstanding except where the result is antidilutive.
 
     Loss per share for the six months ended June 30, 1994 and 1995 is based
upon 5,240,490 and 5,738,825 weighted average common shares outstanding,
respectively.
 
  (m) Accounting Changes
 
     In May 1993 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." As permitted under the Statement, the Company
elected to adopt the provisions of the new standard as of the end of 1993. In
accordance with the Statement, prior period financial statements were not
restated to reflect the change in accounting principle. The cumulative effect as
of December 31, 1993, of adopting Statement 115, including the reversal of
unrealized losses, increased net income by $169,308. The balance of
stockholders' equity was decreased by $169,308 at December 31, 1993, to reflect
the net unrealized holding loss on securities classified as available-for-sale.
 
  (n) Reclassifications
 
     Certain prior period amounts have been reclassified to conform to current
year presentation.

  (o) Interim Periods
 
     The consolidated balance sheet at June 30, 1995 and the consolidated
statements of operations and cash flows for the six month periods ended June 30,
1994 and 1995, and the consolidated statement of stockholders' equity for the
six month period ended June 30, 1995, together with the related notes, are
unaudited, but, in the opinion of management of the Company, include all
adjustments (which consist of normal recurring accruals) necessary to present
fairly, in all material respects, the financial condition at June 30, 1995 and
the results of operations and cash flows for the Company for the six month
periods ended June 30, 1994 and 1995.
 
(2) ACQUISITION AND DISPOSITION OF ASSETS
 
     On June 23, 1992, the Company purchased from McGaw, Inc. (McGaw)
substantially all of the assets related to McGaw's "ACTester(TM)" product line
for approximately $521,557 cash (including $20,719 of related acquisition
costs). The ACTester product line consists of instrumentation and associated
disposables used to measure the activated clotting time (ACT) of blood, a key
parameter in managing patient coagulation status in catheterization, ECMO,
cardiovascular surgery, dialysis and other critical care applications.
 
     The acquisition was accounted for as a purchase and, accordingly, the
acquired assets have been recorded at their estimated fair values at the date of
acquisition. The operating results are included in the 1992 consolidated
statement of operations from the acquisition date. The purchase price and
expenses associated with the acquisition exceeded the fair values of the
acquired assets by $110,179 which has been included in "Costs in excess of net
assets acquired, net" in the consolidated balance sheets. The costs in excess of
net assets acquired is being amortized on a straight-line basis over a 25 year
period.
 
     During December 1992, the Company wrote-off the assets of Clini-Therm
Corporation acquired in July 1991, resulting in a non-recurring, non-cash charge
to operations of $1,246,913. The write-off was initiated by the Company's
intention to focus research and development investments in its core
cardiovascular market.
 
     On March 31, 1995, the Company acquired for $15,403,263 cash (including
$200,000 paid in June 1995 as a purchase price adjustment, and excluding
$926,822 of related acquisition and financing costs) and 833,333 shares of Quest
common stock valued at $6,458,331, all of the capital stock of Neuromed, Inc.
("Neuromed"), a privately held corporation located in Fort Lauderdale, Florida.
The transaction also provided for contingent consideration of up to $6 million
over the next two years, payable in a combination of cash and additional shares
of Quest common stock in January 1996 and January 1997, depending on sales of
Neuromed's products reaching certain objectives. Financing for the cash portion
of the purchase price was provided by NationsBank of Texas, N.A. (See note 3.)
 
     Neuromed develops, manufactures, and markets electronic neurostimulation
devices for treatment of chronic severe pain. Neuromed's revenues for the fiscal
year ended October 31, 1994, were approximately $8.0 million.
 
     The acquisition was accounted for by the purchase method of accounting. The
allocation of the purchase price among identifiable tangible and intangible
assets was based on the fair market value of those assets using a risk adjusted
income approach. The cost in excess of net assets acquired is being amortized on
a straight line basis over twenty years.
 
     Purchased in-process research and development was identified and valued
through extensive interviews and analysis of data concerning Neuromed's products
under development. Expected future cash flows for products under development
were discounted taking into account economic risks

associated with the inherent difficulties and uncertainty in completing the
products, and thereby achieving technological feasibility, and risks related to
the viability of and potential changes in future target markets. This resulted
in $10,500,000 of purchased research and development which had not yet achieved
technological feasibility and does not have alternative uses. Therefore, in
accordance with generally accepted accounting principles, the $10,500,000, with
no related tax benefit, was charged to expense during the six month period ended
June 30, 1995.
 
     The preliminary purchase price allocation for the acquisition of Neuromed,
as of June 30, 1995 is summarized below:

     The preliminary purchase price allocation is subject to change when
additional information concerning asset and liability valuations is obtained.
Therefore, the final allocation may differ from the preliminary amounts
recorded. In connection with the purchase, the Company determined that the
operations of Neuromed will be relocated to Texas by the end of the first
quarter of 1996. The Company is in the process of finalizing the estimated costs
of the relocation which will be recorded in the third quarter of 1995 as an
adjustment to costs in excess of net assets acquired.
 
     The following unaudited pro forma summary presents the results of
operations as if the acquisition had occurred on January 1, 1994. This summary
does not purport to be indicative of what would have occurred had the
acquisition been made as of this date or of results which may occur in the
future. This method of combining the companies is for the presentation of
unaudited pro forma summary results of operations. Actual statements of
operations of Quest Medical, Inc. and of Neuromed, Inc. will be combined from
the effective date of the acquisition forward, with no retroactive restatement.

     The pro forma operations information excludes the non-recurring charge of
$10,500,000 ($1.72 per share) related to purchased in-process research and
development which is expensed at the date of acquisition.
 
     In July 1995, the sales objectives were reached which triggered a liability
for the 1996 contingent consideration payments with regard to the Neuromed
Acquisition. The Company recorded the additional "earn-out" consideration of
200,000 shares of Quest Medical common stock valued at $2,558,200 and a $1.5
million liability (payable in cash in January 1996). In addition, in September
1995, the Company amended certain terms of the acquisition agreement whereby the

accelerate issuance of the 200,000 shares for the 1996 earn-out and the seller
relinquished certain rights from the previous agreement. The amended agreement
sets the 1997 contingent consideration at a cash payment equal to $1.5 million
plus an amount equal to the value of 200,000 shares of common stock at the net
offering price of shares issued in connection with the Offering contemplated by
the Prospectus in which these financial statements are included.
 
(3) CURRENT AND LONG-TERM DEBT
 
     At December 31, 1994, the Company has two credit line facilities. These
facilities expire on September 30, 1995, and include a $3,000,000 working
capital line and a $5,000,000 acquisition line. The lines are collateralized by
the Company's accounts receivable, inventories, machinery and equipment, and in
the case of an acquired business, the purchased assets. Advances under the
$3,000,000 working capital line bear interest at the prime rate plus 25 basis
points or the lender's CD rate plus 150 basis points, at the Company's
discretion. Advances under the $5,000,000 acquisition line bear interest at the
prime rate plus 75 basis points or the lender's CD rate plus 200 basis points,
at the Company's discretion. Advances under the acquisition line are immediately
converted to a five-year term loan. At December 31, 1994 the Company had
advances in the amount of $2,650,000 outstanding under the working capital line
and no advances outstanding under the acquisition line. The Company is subject
to certain covenants related to these facilities. Significant covenants include
the maintenance of a minimum current ratio, ratio of debt to net worth (as
defined) and restricts the payment of cash dividends to 25% of annual net
earnings.
 
     On December 28, 1993, the Company entered into two agreements with MetLife
Capital Corporation for long-term financing on the Allen facility in the amount
of $4,355,071. The first agreement, in the amount of $3,000,000, is related to
the Allen facility building. This loan bears interest at an adjustable rate
based on the 30-day commercial paper rate plus 300 basis points, or the Company
has the option at any time from closing through the first 24 months, to fix the
rate based on the 10-year Treasury Bill rate plus 300 basis points. This note
has a 25-year amortization. The Company has the option of prepaying this note
during years 6-10, subject to certain provisions. The interest rate in effect at
December 31, 1994 was 9.05% and at June 30, 1995 was 9.07%. The loan is
collateralized by the Allen facility building and land and has an unpaid balance
of $2,978,045 at December 31, 1994 and $2,971,950 at June 30, 1995. The second
agreement, in the amount of $1,355,071, is related to certain equipment and
furnishings purchased for the Allen facility. This loan bears interest at an
adjustable rate based on the 30-day commercial paper rate plus 250 basis points,
or the Company has the option at any time from closing through the first 24
months, to fix the rate based on the 5-year Treasury Bill rate plus 250 basis
points. This note has a 10-year amortization. The interest rate in effect at
December 31, 1994, was 8.29% and 8.57% at June 30, 1995. This loan is
collateralized by the equipment and furnishings purchased with the proceeds and
has an unpaid balance of $1,255,049 at December 31, 1994 and $1,207,647 at June
30, 1995.
 
     At December 31, 1994, the Company has 8.625% and 8% notes available that
are secured by certain Company marketable securities, held by investment
companies. These marketable securities have a carrying value of $1,083,060 and
$1,212,112, respectively. Borrowings under these notes are restricted to 50% of
the market value of these marketable securities held by investment companies. At
December 31, 1994, the amounts available for total borrowings were $541,530 and
$606,056, respectively. At December 31, 1994, the Company had no advances
outstanding with respect to these notes. At June 30, 1995, the Company had a 9%
note payable for $245,932. This note was collateralized by certain of the
Company's investments, held by the investment company, which had a carrying
value of $1,153,965. Borrowings under this note are restricted to 50% of the
market value of certain of the Company's investments held by the investment
company. At June 30, 1995, the amount available for additional borrowing under
this note was $331,050.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Total interest incurred during 1993 was $164,777. Capitalized interest, in
conjunction with the construction of the Allen facility in 1993 was recorded as
part of the building, and is amortized over the building's useful life. In 1993,
$82,977 of interest costs were capitalized. No interest was capitalized in 1994
and 1992.
 
     On March 31, 1995, the Company entered into a First Amended and Restated
Credit Agreement with NationsBank of Texas, N.A. (the "Loan Agreement"). The
Loan Agreement provided for $15 million in senior term financing, which was
utilized to pay the cash portion of the Neuromed purchase price (See Note 2),
and a working capital line of up to $5 million. Amortization of the senior term
debt is $1,950,000 per year for the first and second years, $3,250,000 per year
for the third and fourth years, and $2,600,000 for the fifth year, with a
$2,000,000 balloon payment due at the end of the fifth year. Borrowings under
the working capital line are due and payable on May 31, 1997. Borrowings under
both facilities bear interest at prime plus 125 basis points, or at the
Company's option, LIBOR plus 300 basis points. The interest rate can be reduced
based on the Company achieving certain ratios of senior bank debt to EBITDA
(earnings before interest, taxes, depreciation, and amortization). At June 30,
1995, the Company had an outstanding principal balance of $14,512,500 under the
senior term debt, including a current portion of $1,950,000, with a weighted
average interest rate of 9.49%. At June 30, 1995, the Company had borrowings
under the working capital line of $4,200,000 with a weighted average interest
rate of 9.09%.
 
     The aforementioned facilities with NationsBank are collateralized by
certain of the Company's assets, including without limitation, accounts
receivable, inventory, equipment, furniture and other fixed assets, patents,
trademarks and other intangible property, and the Neuromed common stock, but
excluding marketable securities in excess of $2 million, and excluding the real
property, building, and equipment financed in 1993 by MetLife Capital
Corporation. The Company is subject to certain covenants related to the
NationsBank debt. Significant covenants include the maintenance of a minimum
current ratio, ratio of debt to net worth (as defined) and restrictions on the
payment of cash dividends to 25% of annual net earnings.
 
(4) FEDERAL INCOME TAXES
 
     The Company adopted the provisions of the Statement on Financial Accounting
Standards No. 109, "Accounting for Income Taxes" (Statement No. 109), effective
January 1, 1993. The cumulative effect of adopting Statement No. 109 was not
material. Under Statement No. 109, deferred tax assets and liabilities are
recognized using the liability method, whereby tax rates are applied to
cumulative temporary differences based on when and how they are expected to
effect the tax return. Prior to the adoption of Statement No. 109, income tax
expense was determined using the provisions of FAS No. 96.
 
     The significant components of the net deferred tax liability at December
31, were as follows:

     During the years ended December 31, 1992 and 1993, the Company realized
$189,219 and $187,236, respectively, of tax benefits from stock option
deductions which has been credited to paid-in capital.
 
     At December 31, 1994, general business credits of $751,912 and alternative
minimum tax credits of $134,284 are available to offset future tax liabilities.
If unused, the general business credits expire in various amounts beginning in
1997 through 2009.
 
     During the period ended June 30, 1995, the Company eliminated the valuation
allowance for deferred tax assets that was recorded in prior years of
$1,745,090. The elimination of the valuation allowance was recorded as a
reduction of costs in excess of net assets acquired because the reduction
resulted from deferred tax liabilities recorded in connection with the
acquisition of Neuromed.
 
(5) STOCK PURCHASE RIGHTS
 
     On October 12, 1989, the Company declared a distribution to stockholders of
record on October 23, 1989, of one common stock purchase right for each
outstanding share of common stock. Each right

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
entitles the holder to purchase one-half of a share of common stock at an
exercise price of $5.00. The purchase price payable and the number of shares
issuable upon exercise of the rights are subject to adjustment by the Company in
order to prevent dilution. The rights are not exercisable or transferable apart
from the common stock until ten days after a public announcement that a person
or group either (1) has acquired or has obtained the right to acquire 15% or
more of the Company's outstanding shares of common stock, or (2) has commenced
or announced an intention to commence a tender offer or exchange offer for 20%
or more of the outstanding shares of common stock. Until a right is exercised,
the holder of a right, as such, will have no rights as a stockholder of the
Company, including, without limitation, the right to vote as a stockholder or
receive dividends.
 
     The rights may be redeemed in whole by the Company at a price of $0.01 per
right at any time prior to their expiration on October 12, 1999, or prior to the
point at which they become exercisable.
 
     Under certain circumstances described in the rights agreement, the holder
will be entitled to purchase at the current exercise price that number of shares
of common stock of the acquiring company having a market value of two times the
exercise price of the right.
 
     On February 9, 1995, the Board of Directors amended two provisions of the
rights agreement. First, the purchase price (as defined in the rights agreement)
for each one-half share of common stock purchased pursuant to the exercise of
the right was increased from $5.00 to $12.50. Secondly, the definition of
acquiring person was amended to exclude Mr. Borkan or his affiliates so long as
their ownership does not exceed 25% of the common shares outstanding at any
time.
 
(6) STOCK OPTIONS
 
     At December 31, 1994, under the Company's stock option plans, options may

options may be granted to key employees (Employees' Plan) and 557,635 options
may be granted to directors and advisory directors (Directors' Plan). These

Directors' Plan have a special two year vesting schedule. These options are
exercisable one-half each year over a two-year period. The stock options granted
under the Employee's Plan expire ten years from the date of grant. The stock

Officers or other key employees of the Company are eligible to receive stock
option grants under the Plan. The per share exercise price of each option is
determined by the Stock Option Committee of the Board of Directors, but in no
event is less than the Fair Market Value of the Common Stock at the time the
option is granted. Generally, each option will be for a term of not less than
five years nor more than ten years from the date of grant. Vesting of the
options will be determined by the Stock Option Committee, although for the most
part, options will become exercisable with respect to 25% of the total number of
shares subject to the option twelve months after the date of grant and with
respect to an additional 25% at the end of each twelve-month period thereafter
on a cumulative basis during the succeeding three years. The plan was approved
by the shareholders of the Company at the Annual Meeting of Shareholders held on
June 22, 1995.
 
     A summary of transactions through June 30, 1995 follows:

(8) FINANCIAL INSTRUMENTS, RISK CONCENTRATION, AND MAJOR CUSTOMERS
 
     The Company designs, develops, manufactures and markets a variety of
healthcare products used primarily in cardiovascular surgery, interventional
pain management and intravenous fluid delivery applications. In the United
States, the Company's accounts receivable are due primarily from hospitals and
distributors located throughout the country. Internationally, the Company's
accounts receivable are due primarily from distributors located in Europe and
Australia. The Company generally does not require collateral. The Company
maintains an allowance for doubtful accounts based upon the expected
collectibility of all accounts receivable. Any losses from bad debts have
historically been within management's expectations.
 
     Net sales to a major customer for each of the years ended December 31, as a
percentage of total net revenues were as follows: 1992 -- 25%, 1993 -- 23%, and

the Company to make matching contributions equal to 50% of the participants'
contributions, to a maximum of 6% of the participants' compensation. The expense

     On May 13, 1993, the Company entered into a settlement agreement relating
to the litigation it filed on April 20, 1990, against Kirschner Medical
Corporation, its directors and Alex Brown and Sons, Inc. Under the terms of the
settlement agreement, the Company received $600,000 cash and 100,000 warrants to
purchase Kirschner Medical common stock for three years at an exercise price of
$6.00 per share. Each warrant is convertible into one share of Kirschner Medical
common stock. The Company incurred litigation expenses of approximately
$201,000. The Company recorded a pre-tax gain of $524,200 which is reflected in
"Other income (expenses) -- Litigation settlements, net" in the Consolidated
Statements of Operations.
 
     During October 1993, an agreement was reached to settle a lawsuit filed
against the Company on November 2, 1992, in the United States Bankruptcy Court
for the Northern District of Texas by Jeffery Mims, Trustee for Clini-Therm
Corporation. The complaint alleged the Company fraudulently purchased claims
from Ford Motor Credit Corporation and unfairly rescinded its agreement to
finance Clini-Therm's reorganization. The Company recorded a pre-tax charge of
$357,112 (including $157,112 of litigation expense) which is reflected in "Other
Income (expenses) -- Litigation settlement, net" in the Consolidated Statements

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Neuromed, Inc.
 
     We have audited the accompanying consolidated balance sheet of Neuromed,
Inc. and subsidiaries (the "Company") as of October 31, 1994, and the related
consolidated statements of income and retained earnings, and cash flows for each
of the two years in the period ended October 31, 1994. These consolidated
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 consolidated financial position of Neuromed, Inc.
and subsidiaries at October 31, 1994, and the consolidated results of their
operations and their cash flows for each of the two years in the period ended
October 31, 1994, in conformity with generally accepted accounting principles.
 
     As discussed in Note 8 to the financial statements, in fiscal 1994, the
Company changed its method of accounting for income taxes.

          (INFORMATION SUBSEQUENT TO OCTOBER 31, 1994, AND INFORMATION
           FOR THE THREE MONTHS ENDED JANUARY 31, 1994 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  General
 
     Neuromed, Inc. and subsidiaries manufacture implantable medical devices
used for neurostimulation. The devices manufactured include multi-programmable
spinal cord stimulators using various electrode types and multi-programmable
deep brain stimulators. They are used primarily for the treatment of chronic
pain.
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of Neuromed,
Inc. and its wholly-owned subsidiaries ("Neuromed" or the "Company"). All
significant intercompany accounts and transactions have been eliminated in
consolidation.
 
  Cash and Cash Equivalents
 
     For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with an original maturity of three
months or less to be cash equivalents. The carrying amount of cash and cash
equivalents approximate their fair value.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
  Property, Plant and Equipment
 
     Property, plant and equipment are recorded at cost. Depreciation is
computed using straight-line and accelerated methods over the estimated useful
lives of the assets. Amortization of leasehold improvements is computed on a
straight-line basis over the lesser of the useful life of the asset or the term
of the lease.
 
  Income Taxes
 
     Effective November 1, 1993, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this
statement, deferred tax assets and liabilities are determined based upon the
difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse.
 
  Interim Periods
 
     The consolidated balance sheet at January 31, 1995 and the consolidated
statements of income and retained earnings and consolidated statements of cash
flows for the three month periods ended January 31, 1994 and 1995, together with
the related notes, are unaudited, but, in the opinion of management of the
Company, include all adjustments (which consist of normal recurring accruals)
necessary to present fairly, in all material respects, the financial condition
at January 31, 1995 and the results of operations and cash flows for the Company
for the three month periods ended January 31, 1994 and 1995.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Effective November 1, 1993, the Company changed its method of accounting
for income taxes from the deferred method to the liability method required by
SFAS No. 109. As permitted under the new rules, prior years' financial
statements have not been restated. The cumulative effect of adopting SFAS No.
109 as of November 1, 1993 was to increase net income by $261,285.
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities as of October 31, 1994 are as

     In 1993, the Company's effective tax rate was less than the federal
statutory rate of 34% primarily because of the utilization of research and
development credits. The Company's effective tax rate for 1994 and for the three
months ended January 31, 1994 and 1995 differs from the federal statutory rate
of 34% primarily because of state income taxes.
 
9. MAJOR CUSTOMER
 
     In 1993 a major customer accounted for 13% of sales. The Company's major
customer in 1994 accounted for 18% of sales. During 1993 and 1994, a company in
which the principal shareholder of Neuromed holds a minority interest accounted
for 18% and 7% of sales, respectively.
 
10. SUBSEQUENT EVENT
 
     On March 31, 1995, the sale of all the capital stock of the Company to
Quest Medical, Inc. was closed. Pursuant to the agreement, all of the cash on
hand at that date was distributed to the principal shareholder of the Company.
Also pursuant to such closing, the agreement by Neuromed to pay certain research
and development expenses for an affiliated company was terminated and the
deferred compensation described in Note 4 was cancelled.

                CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS
 
NOTE A. BASIS OF PRESENTATION
 
     On March 31, 1995, pursuant to the terms of an Agreement for the Purchase
and Sale of all of the Issued Capital Stock of Neuromed, Inc. between Quest
Medical, Inc. ("the Company") and Mr. William Borkan dated February 10, 1995,
the Company acquired all of the issued and outstanding stock of Neuromed, Inc.
("Neuromed"). In consideration for its purchase of the Neuromed capital stock,
the Company paid $15,403,265 in cash and 833,333 shares of Quest common stock
valued at $6,458,331. The Company may also be required to pay contingent
consideration of up to $6 million over the next two years payable in January
1996 and January 1997, depending on sales of Neuromed's products reaching
certain established objectives. The contingent considerations may be paid in a
combination of cash and additional shares of Quest Common stock. In addition,
the Company incurred $926,824 of acquisition-related expenses (including debt
issuance cost). In connection with the acquisition of Neuromed, the Company
entered into the First Amended and Restated Credit Agreement dated March 31,
1995 with NationsBank of Texas, N.A. (the "Loan Agreement"). The Loan Agreement
provided the Company with $15 million in senior term financing, which was
utilized to pay most of the cash portion of the Neuromed purchase price. The
Loan Agreement also expanded the Company's existing $3 million working capital
line of credit to $5 million. The acquisition has been accounted for using the
purchase method of accounting.
 
     The pro forma condensed consolidated statements of operations for the year
ended December 31, 1994 and the six months ended June 30, 1995 have been
prepared as if the acquisition of Neuromed had occurred on January 1, 1994. The
pro forma condensed consolidated statement of operations for the year ended
December 31, 1994 combines the statement of operations of Quest Medical for the
twelve months ended December 31, 1994 and the statement of income of Neuromed
for the twelve months ended October 31, 1994. The pro forma condensed
consolidated statement of operations for the six months ended June 30, 1995
combines the statement of operations of Quest Medical for the six months ended
June 30, 1995 and the statement of income of Neuromed for the three months ended
January 31, 1995.
 
     The unaudited pro forma condensed consolidated financial statements have
been prepared based on estimates and assumptions deemed by the Company to be
appropriate and do not purport to be indicative of the financial position or
results of operations which would actually have been obtained had the
acquisition occurred as presented in such statements or which may be obtained in
