ITEM 1.   DESCRIPTION OF BUSINESS

GENERAL

Quest Medical, Inc., a Texas corporation ("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
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, Inc. ("Neuromed"), which designs, develops, manufactures and markets a
line of electronic spinal cord stimulation ("SCS") devices used to manage
chronic severe pain.

The Company was formed in 1979, and shortly thereafter became the successor to
the business of Med-Pro, Ltd., a four-year-old research and development medical
device company. Until September 1987, when it sold such business, Quest
developed, manufactured and marketed electronic volumetric intravenous infusion
devices and related disposables in addition to its other products.

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 received 510(k) market


                                       -1-



<PAGE>   3

clearance for its MPS system from the FDA in March 1996. Upon the completion of
clinical validation expected in the second quarter of 1996, management expects
to commence commercial shipment of MPS.

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.

                                    PRODUCTS

The following table summarizes certain information with respect to the Company's
principal products in commercial distribution and under development.

CARDIOVASCULAR

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. During the years ended December 31,
1995, 1994, and 1993, the Company's valves, filters and traps accounted for $5.2
million, $4.2 million, and $3.7 million, respectively, of total net revenue.

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


                                       -3-


<PAGE>   5


measure the activated clotting time of blood. During the years ended December
31, 1995, 1994, and 1993, the Company's surgical tapes and other products
accounted for $1.8 million, $1.6 million, and $1.6 million, respectively, of
total net revenue.

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.

The Company subsequently developed, and in August 1995 filed a 510(k) with the
FDA for, the MPS system. In March 1996, the Company received clearance from the
FDA to market MPS and is engaged in clinical testing of the system. Upon
completion of such testing, expected in the second quarter of 1996, management
expects to commence commercial shipment of MPS.

The MPS 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 when the instrument is released to market.

INTERVENTIONAL PAIN MANAGEMENT

Background. 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 



                                       -4-



<PAGE>   6




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.

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 lPG 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 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.

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


                                       -5-

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.

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





                                       -6-

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 Item 1: "Business -- Other Business
Matters -- Government Regulation."

During the year ended December 31, 1995, the Company's SCS products accounted
for $10.4 million of total net revenue.

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 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.  See Item 1: 
"Business -- Other Business Matters -- Marketing and Major Customer." During the
years ended December 31, 1995, 1994, and 1993 the Company's intravenous fluid
delivery products accounted for $6.0 million, $6.3 million, and $6.8 million,
respectively, of total net revenue.

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. During the






                                       -7-



<PAGE>   9


years ended December 31, 1995, 1994, and 1993 the Company's other products
(primarily pressure monitoring kits) accounted for $1.8 million, $1.9 million,
and $1.6 million, respectively, of total net revenue.

                             OTHER BUSINESS MATTERS

MARKETING AND MAJOR CUSTOMER

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. 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 at year-end 1995 employed five sales managers, four of
which were hired during the fourth quarter of 1995. The Company has received
510(k) clearance for the MPS system, as previously noted, and
plans to introduce MPS commercially during the second quarter of 1996. The
Company plans to add seven additional salespersons throughout 1996 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
also employs one sales manager who oversees the distributors who sell the
Company's pressure monitoring kits. 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 84% of net revenues attributable to its SCS
devices from domestic sales and approximately 16% from European and Australian
sales.

The University of Texas Cancer Center (M.D. Anderson Hospital) accounted for
$2.6 million, $2.7 million, and $3.1 million, or 10%, 19% and 23%, of the
Company's net revenues for the years ended December 31, 1995, 1994 and 1993
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 and are expected to decline further as a result of the
Neuromed acquisition and introduction of MPS, the loss of this customer could
have a material adverse effect on the Company's business, financial condition
and results of operations.

RESEARCH AND DEVELOPMENT





                                       -8-



<PAGE>   10


Since 1992, the Company has focused its research and development efforts on
designing and developing the MPS system and related products. The Company has
spent $10.3 million on the research and development of its MPS system and
related products, representing over 90% 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 from peak levels during
1995, as a result of completing development of the MPS system and certain
related products during 1995. Research and development expense was $4.6 million,
$3.5 million and $1.9 million for the years ended December 31, 1995, 1994 and
1993, respectively. The Company has budgeted $3.3 million for research and
development during 1996. Management expects 60% of such expenditures to be
directed to refining and redesigning of Neuromed SCS products with the remainder
directed primarily to MPS. As of March 21, 1996, the Company had an in-house
research and development staff of 24 engineers, technicians and designers, down
from a peak number of 49 during April 1995.

MANUFACTURING

The Company manufactures and packages certain cardiovascular products (such as
pressure control valves, filters, traps, MPS 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 Item 1. "Business -- Other Business
Matters -- Government Regulations." Until the first quarter of 1996, when such
operations were moved to the Allen, Texas facility, the Company manufactured its
line of SCS devices and related products at an ISO 9002 certified (manufacturing
only) facility in Fort Lauderdale, FL. Finally, the 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.






                                       -9-



<PAGE>   11



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 and Orange
County areas.

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.

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.

<PAGE>   12


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.

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 technologies, manufacturing capability, close customer relations and
support and its strategy to increase its offerings of products within these
markets.

PATENTS, TRADEMARKS AND PROPRIETARY INFORMATION

The Company owns eighteen United States patents relating to products that the
Company currently sells or develops. Although one of the Company's patents
expired 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. Eleven of
the eighteen 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 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.

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 







                                      -12-

<PAGE>   14


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.

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 canceled 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 "Designated
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,






                                      -14-


<PAGE>   16


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.

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






                                      -15-



<PAGE>   17

development or increased use of more cost-effective treatments could cause such
payors to decrease or deny reimbursement to favor these other treatments.

EMPLOYEES

As of March 21, 1996, the Company employed 250 full-time employees, 24 in
research and development, 44 in sales and marketing, 156 in manufacturing and
related operations, and the remainder in executive and administrative positions.
This is an increase of 67 employees from the number at March 17, 1995. Of such
increase, 56 personnel were added to the employee base from the Neuromed
acquisition. The remainder of the increase is primarily due to additional sales
and marketing personnel in preparation for the commercial introduction of MPS.
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.

ITEM 2.       DESCRIPTION OF PROPERTY

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 5 of the Notes to Consolidated Financial
Statements. Management expects the 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.






                                      -16-

Neuromed leased, until February 1996 when such lease expired, approximately
18,000 square feet of office and manufacturing space in Fort Lauderdale,
Florida, where it manufactured and marketed its SCS devices. During late 1995
and early 1996, the Company relocated the Neuromed operations to the Company's
facility in Allen, Texas.

ITEM 3.    LEGAL PROCEEDINGS

As a consequence of the Neuromed Acquisition in March 1995, the Company is
currently a party to certain product liability claims related to SCS devices
sold by Neuromed prior to the acquisition. 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.

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.

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 cash dividends to 75% of
annual net earnings (as defined in the credit agreement) if no draws exist under
the acquisition line of credit and 25% of annual net earnings if the acquisition
line of credit has been drawn upon.

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, 1995, the Company repurchased no shares
of common stock. During 1995, the Company issued 1,033,333 shares of common
stock from its treasury as partial consideration in the acquisition of Neuromed,
Inc. In addition, during the fourth quarter of 1995, the Company completed a
public offering in which it issued 1,676,667 shares, almost







                                      -18-

<PAGE>   20


all of which were issued from its treasury. The Company received net proceeds of
$15.2 million which were used to repay $13.9 million of senior bank
indebtedness. At December 31, 1995, the Company had no shares in its treasury
and does not anticipate further repurchases during the foreseeable future.

ITEM 6.    MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The following discussion of the financial condition and results of operations of
the Company should be read in conjunction with the Consolidated Financial
Statement of the Company and the related Notes thereto.

OVERVIEW

On March 31, 1995, the Company acquired all of the issued and outstanding
capital stock of Neuromed, Inc., which was held by Mr. William Borkan and his
brother, Mr. Burt Borkan. The Neuromed acquisition was 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 then at $6.5 million. The Company also incurred
$1.1 million 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 public offering completed in November 1995 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 the public
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 public offering price ($9.35 per share after underwriting discounts
and commissions).

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 Neuromed purchase price. The Company has
also drawn down $4.5 million on the working capital line of credit. This bank
debt was 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 also excluded the Company's real property, building, and certain
equipment in Allen, Texas, which collateralize financing provided in 1993 by
MetLife Capital Corporation.





                                      -19-


<PAGE>   21


On November 15, 1995, the public offering of 2,400,000 shares of Common Stock
was completed. Of these shares, 1,316,667 were sold by the Company and 1,083,333
were sold by selling shareholders (1,033,333 shares by the Borkans). The Company
received $11.8 million, after deducting underwriters' discounts and commissions
and offering expenses payable by the Company. In addition, on December 6, 1995,
the Company sold an additional 360,000 shares (the "green shoe") and received
net proceeds of $3.4 million. The Company utilized $13.9 million of the proceeds
from the offering to repay in its entirety the senior term bank debt with
NationsBank. At year end 1995, the Company had a commitment from NationsBank to
provide, in addition to the $5.0 million working capital line, a $15 million
acquisition line of credit. The Company entered into a Second Amended and
Restated Credit Agreement on February 9, 1996, which provided for the $15.0
million acquisition line of credit and $5.0 million working capital line of
credit.

RESULTS OF OPERATIONS

Comparison of the Years Ended December 31, 1995 and 1994

Revenues. Net revenue of $25.3 million for the year ended December 31, 1995, was
$11.3 million, or 80.7% above the level for the comparable 1994 period of $14.0
million. This increase during 1995 compared to 1994 was primarily attributable
to revenue generated by Neuromed, which was acquired on March 31, 1995. See Item
1: "Business" and Note 3 of the Notes to Consolidated Financial Statements.
Neuromed develops, manufactures and markets a line of electronic spinal cord
stimulation ("SCS") devices used to manage chronic severe pain. Net revenue from
sales of the Company's other products increased 6.3% during 1995 compared to
1994 primarily due to higher unit sales volume from the Company's cardiovascular
products.

During August 1995, the Company filed for FDA market clearance under a
pre-market notification ("510(k)") on its MPS(TM) brand of myocardial protection
system. On March 8, 1996, the Company received clearance from the FDA to
commercially market the MPS system and related products and expects to introduce
the MPS system during the second quarter of 1996. Management expects that
Neuromed and MPS should enhance the long-range growth objectives of the Company.

Gross Profit. Gross profit during 1995 increased to $14.7 million compared to
$6.4 million in 1994, an increase of 130%. As a percentage of net revenue, gross
profit increased to 58.0% in 1995 compared to 45.6% during 1994. This increase
in gross profit and gross profit margin during 1995 compared to 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.

Operating Expenses. Research and development expense increased to approximately
$4.6 million during 1995 compared to the 1994 level of $3.5 million, although
such expense decreased as a percentage of net revenue from 25.3% during 1994 to
18.1% during 1995. These expenditures during 1995 were $2.1 million more than
originally budgeted at the beginning of fiscal 1995. Of such overage, $650,000
were expenditures directed toward newly acquired Neuromed while the remainder
represented additional expenditures directed at continued development of the
Company's MPS(TM) brand of myocardial protection system. See Item 1: "Business
- -- Other Business Matters -- Research and Development".







                                      -20-

Myocardial protection is the process of arresting and caring for the heart
during open-heart surgery. The 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 Company's MPS system
features an electronic console and includes a line of captive and non-captive
disposable products. As previously noted, the Company filed for FDA market
clearance under a 510(k) during August 1995 and on March 8, 1996 received
clearance to commercially market the MPS system, which management believes will
occur during the second quarter of 1996. Increased expenditures during 1995
compared to 1994 were primarily the result of additional salary and contract
labor expense from staff additions and increased consulting expense.

The Company has budgeted $3.3 million for research and development activities
during 1996. Management expects that about 60% of such expenditures to be
directed to refining and redesigning of Neuromed products, with the remainder
directed primarily to continued development of MPS and related products.
Management expects that most of its research and development activities in
fiscal 1996 will be Company-sponsored and funded through its operations.

Marketing, general and administrative expenses as a percent of net revenue
decreased to 33.2% during 1995 compared to 35.6% during 1994, while the dollar
amount increased $3.4 million. Marketing expense as a percentage of net revenue
increased to 16.6% in 1995 from 13.7% during 1994, and the dollar amount
increased by $2.3 million. Of such increase, $1.7 million 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, convention and recruiting expense. During the
fourth quarter of 1995, the Company hired four additional direct salespersons in
anticipation of the 510(k) clearance of its MPS system. Management expects to
introduce the MPS system during the second quarter of 1996 and anticipates
adding seven salespersons throughout 1996 to market the MPS system and related
products. General and administrative expense increased $1.1 million during 1995
compared to 1994, but as a percentage of net revenue, decreased from 21.9%
during 1994 to 16.6% during 1995. This increase in expense during 1995 compared
to 1994 was 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, Inc. See Note 3 of the Notes to Consolidated Financial
Statements. Of the aggregate purchase price for Neuromed, $10.5 million was
identified as purchased in-process research and development and in accordance
with generally accepted accounting principles was charged to expense, with no
related tax benefit, during 1995. As a result, the loss from operations
increased from $2.1 million in 1994 to $8.8 million during 1995. Excluding the
charge for purchased research and development, the Company generated earnings
from operations of $1.7 million compared to the $2.1 million loss for the 1994
period, reflecting the positive impact of the Neuromed acquisition.






                                      -21-


<PAGE>   23


Other Income (Expense). Other income (expense) decreased to an expense of $1.2
million during 1995 compared to income of $419,000 during 1994. This decrease
was primarily the result of higher interest expense which increased $1.1 million
during 1995 from 1994. 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 3 and 5 of the Notes to
Consolidated Financial Statements. Higher overall interest rates on borrowed
money also contributed to the increase in interest expense during 1995 compared
to 1994. In addition, gains recognized on the sale of the Company's investments
was $29,000 for 1995 compared to $464,000 for 1994, also contributing to the
decrease in other income.

Income Taxes. The Company recorded income tax expense of $155,000 during 1995 as
a consequence of the nondeductibility of the $10.5 million expense for purchased
research and development and amortization expense of costs in excess of net
assets acquired. No income tax benefit was recognized for the Company's 1994 net
operating loss.

Net Loss. The net loss increased from $1.7 million in 1994 to $10.4 million
during 1995 primarily as a result of the aforementioned $10.5 million expense
for purchased in-process research and development incurred in connection with
the Neuromed acquisition. In addition, the net loss for 1995 reflects an
extraordinary charge of $269,000 for the write-off of capitalized debt issuance
costs due to early repayment of the long-term bank debt.

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 Companys'
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 reduction in gross profit
margins for this product line, since manufacturing volumes were reduced, thus
resulting in higher overhead costs per unit.







                                      -22-

<PAGE>   24

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 Item 1.
"Business -- Other Business Matters -- 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 increased its development staff headcount
by fourteen personnel during 1994 bringing its total R&D staff to 39 at
year-end.

Marketing, general and administrative expense as a percent of net revenue
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






                                      -23-



<PAGE>   25


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 stockholder's 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.

LIQUIDITY AND CAPITAL RESOURCES

The Company's working capital of $12.2 million at the end of 1995 increased from
$7.4 million at the end of 1994. The ratio of current assets to current
liabilities was 3.7 to 1 at the end of 1995 and 2.8 to 1 at the end of 1994. The
Company's ratio of long-term debt to total capital was 28% at year-end 1995, up
slightly from 26% at year-end 1994.

As previously noted, the Company completed a public offering during the fourth
quarter of 1995. The total number of shares sold pursuant to the offering were
2,760,000, of which, 1,676,667 shares were sold on the Company's behalf. The
Company's net proceeds from the offering totaled $15.2 million. The Company used
$13.9 million of such proceeds to retire the senior term bank debt which was
incurred during March 1995 to consummate the Neuromed acquisition.

In February 1996, the Company amended its working capital line of credit and
added a $15 million acquisition line of credit with NationsBank. Under the
amended agreement, the working capital line of credit is collateralized by the
Company's accounts receivable and inventory. The acquisition line, if drawn
upon, is collateralized by the Company's remaining unencumbered assets. Both
facilities will expire on December 31, 1997 and bear interest at the prime rate
plus 25 basis points or LIBOR plus 200 basis points, at the Company's
discretion. The interest rate can be reduced based on the Company achieving
certain ratios of senior bank debt to EBITDA. Advances under the acquisition
line are immediately converted to a five-year term loan. The Company is subject
to certain covenants related to the facilities such as, amongst others, current
maturities coverage ratio, fixed charge ratio and total liabilities to tangible
net worth ratio (as defined). The Company is also restricted on the payment of
cash dividends to 75% of annual net earnings if no draws exist under the
acquisition line and 25% of annual net earnings if the acquisition line has been
drawn upon.

Management believes that its current cash, cash equivalents and marketable
securities, funds generated from operations, and if necessary, funds provided by
the working capital line of credit will be sufficient to satisfy normal cash
operating requirements and capital requirements during 1996.

CASH FLOWS

Net cash used by operating activities in 1995 increased slightly to $1.5 million
compared to $1.4 million in 1994. This increase was due to an increase in net
working capital, principally in the areas of accounts receivable, inventory and
prepaid expenses.

Investing activities in 1995 resulted in a net use of cash of $14.1 million
compared to cash being provided by investing activities during 1994 of $320,000.

compared to 1994 was primarily the result of $16.0 million utilized to
consummate the Neuromed acquisition in March 1995. Additionally, capital
expenditures increased to $1.5 million in 1995, an increase of $400,000 from
1994. The sale of certain of the Company's investments in marketable securities
provided $3.3 million of cash, up from $1.3 million in 1994.

Financing activities in 1995 provided $16.9 million of cash compared to $620,000
in 1994. As discussed earlier, during 1995 the Company borrowed $15.0 million of
senior term bank debt to fund most of the cash portion of the Neuromed
acquisition purchase price and increased its borrowings under its working
capital line of credit by $1.9 million. Furthermore, as also discussed earlier,
the Company completed a public offering during 1995 which provided net proceeds
of $15.2 million. These proceeds were utilized to repay the senior term bank
indebtedness.

OUTLOOK AND UNCERTAINTIES

Quest does not provide forecasts of potential future financial performance.
While Quest management is optimistic about Quest's long-term prospects, the
following issues and uncertainties, among others, should be considered in
evaluating its growth outlook.

Product Development and Market Acceptance. The Company's growth depends in part
on the development and market acceptance of new products, including the MPS
system and related products. There is no assurance that the Company will
continue to develop successful products, that delays in product introduction
will not be experienced, or that once such products are introduced, the market
will accept them.

New Business Integration. To the extent the Company's business strategy involves
acquisitions, the integration of acquired businesses can be difficult and
costly. The Neuromed acquisition, for example, will require management time and
attention and will only be fully successful if operations are combined in an
orderly and timely manner.

Government Regulation.  The Company's business is subject to extensive
government regulation, principally by the FDA.  The regulatory process,
especially as it relates to product approvals, can be lengthy, expensive and
uncertain.

Competition and Technological Change. The medical device market is highly
competitive. The Company competes with many larger companies that have access to
greater capital, research and development, marketing, distribution and other
resources than the Company. In addition, this market is characterized by
extensive research efforts and rapid product development and technological
change, which could render the Company's products obsolete or noncompetitive.

Intellectual Property Rights. The Company relies in part on patents, trade
secrets and proprietary technology to remain competitive. It may be necessary to
defend these rights or to defend against claims that the Company is infringing
the rights of others. Intellectual property litigation and controversies are
disruptive and expensive.






                                      -25-

<PAGE>   27


Cost Pressures on Medical Technology. The overall escalating cost of medical
products and healthcare results in significant cost pressure. Third party payors
are under intense pressure to challenge the prices charged for medical products
and services.

Potential Product Liability.  The testing, manufacturing, marketing and sale of
medical devices entail substantial risks of liability claims or product recalls.

Other Uncertainties. Other operating, financial or legal risks or uncertainties
are discussed in the Form 10-K in specific contexts. The Company is, of course,
also subject to general economic risks, the risk of interruption in the source
of supply, the risk of loss of a major customer, dependence on key personnel and
other risks and uncertainties.

IMPACT OF INFLATION AND CHANGING PRICES

The Company attempts to minimize the impact of inflation on manufacturing and
operating costs through on-going quality and productivity programs. The Company
considers the impact of inflation on its operations to be insignificant as the
rate of inflation has declined in recent years. When material price increases
have been experienced by the Company, it has generally attempted to pass such
cost increases on to customers through its prices, to the extent permitted by
competition.

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.

                         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, 1995 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, 1995. 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, 1995 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, 1995, in conformity with generally accepted
accounting principles.

As discussed in Note 4 to the financial statements, in 1993 the Company changed
its method of accounting for certain investments in debt and equity securities.

                      QUEST MEDICAL, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1995

(1)   BUSINESS

      Quest Medical, Inc. and its subsidiaries (the "Company") design, develop,
      manufacture and market a variety of healthcare products used primarily in
      cardiovascular surgery, interventional pain management and intravenous
      fluid delivery applications. The Company's revenues are derived primarily
      from sales throughout the United States, Europe and Australia.

      The research and development, manufacture, sale and distribution of
      medical devices is subject to extensive regulation by various public
      agencies, principally the Food and Drug Administration and corresponding
      state, local and foreign agencies. Product approvals and clearances can be
      delayed or withdrawn for failure to comply with regulatory requirement or
      the occurrence of unforeseen problems following initial marketing. While
      the Company has received clearance for the MPS system, there can be no
      assurance that such clearance will not be withdrawn in the future.

      In addition, the Company's products are purchased primarily by hospitals
      and other users which then bill various third party payors including
      Medicare, Medicaid, private insurance companies and managed care
      organizations. These third party payors reimburse fixed amounts for
      services based on a specific diagnosis. The impact of changes in third
      party payor reimbursement policies and any amendments to existing
      reimbursement rules and regulations which restrict or terminate the
      eligibility of the Company's products could have an adverse impact on the
      Company's financial condition and results of operations.

(2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The consolidated financial statements include the accounts of Quest
      Medical, Inc. and subsidiaries. All significant intercompany balances and
      transactions have been eliminated in consolidation. The preparation of
      financial statements in conformity with generally accepted accounting
      principles requires management to make estimates and assumptions that
      affect the reported amounts of assets and liabilities and disclosure of
      contingent assets and liabilities at the date of the financial statements
      and the reported amounts of revenues and expenses during the reporting
      period. Actual results could differ from these estimates.

      Revenue from product sales is recognized at the time the product is
      shipped.

      Cash equivalents include certificates of deposit and short-term, highly
      liquid debt instruments with original maturities of three months or less.

      Effective December 31, 1993, the Company's marketable equity and debt
      securities are classified as available-for-sale and 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 are included in investment income. Prior to December 31, 1993,
      marketable securities were accounted for at the lower of cost or market.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


      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.

      Property, plant and equipment are stated at cost. Major renewals and
      betterments are capitalized; maintenance and repairs are charged to
      operations as incurred. 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.

      The excess of costs over the net assets of businesses acquired is
      amortized on a straight line basis over the 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, 1995, the
      Company does not believe there has been any impairment of its intangible
      assets.

      Cost of purchased patents is amortized on a straight-line basis over the
      estimated useful lives (4 to 14 years) of such patents. Costs of patents
      which are the result of internal development are charged to current
      operations.

      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.

      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.

      Product development costs including start-up, research and development,
      advertising and promotional costs are charged to operations in the year in
      which such costs are incurred.

      Primary and fully diluted earnings per share for 1995, 1994, and 1993 are
      based upon 6,642,082, 5,256,683 and 5,559,422 common and common equivalent
      shares outstanding, respectively. Common stock equivalents are outstanding
      stock options and are included in average common and common equivalent
      shares outstanding using the treasury stock method except during periods
      where their effect would be antidilutive. During 1994, the Board of
      Directors approved a 3% stock dividend. The weighted average number of
      common and common equivalent shares outstanding used in computing 
      earnings per share were increased to retroactively reflect the stock
      dividend.

      Deferred income taxes are recorded based on the liability method and
      represent the tax effect of the differences between the financial and tax
      basis of assets and liabilities other than costs in excess of the net
      assets of businesses acquired.

      Certain prior period amounts have been reclassified to conform to current
      year presentation.


                                                                     (Continued)

(3)   ACQUISITION

      On March 31, 1995, the Company acquired for $15,403,263 cash (excluding
      $1,062,414 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"). The transaction also provided for contingent
      consideration over the following 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 a bank. (See Note 5.)

      In July 1995, the sales objectives for 1995 were reached which triggered a
      liability for the 1995 contingent consideration payments with regard to
      the Neuromed acquisition. The Company recorded the additional "earn-out"
      consideration of 200,000 shares of Quest common stock valued at $2,558,200
      and a $1,500,000 liability (payable in cash in January 1996). In addition,
      in September 1995, the Company amended certain terms of the acquisition
      agreement whereby the Company agreed to accelerate issuance of the 200,000
      shares for the 1995 earn-out and the seller relinquished certain rights
      from the previous agreement. The amended agreement sets the 1996
      contingent consideration, payable in January 1997, at a cash payment equal
      to $3,370,000, if earned.

      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 upon 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 year ended December 31, 1995.

      The purchase price allocation for the acquisition of Neuromed, as of
      December 31, 1995 is summarized below:

      Tradenames                                              $ 2,500,000
      Purchased technology                                      4,000,000
      Cost in excess of net assets acquired                     8,873,391
      Purchased research and development                       10,500,000
      Net tangible assets acquired                                640,050
      Deferred financing costs                                    468,767
                                                              -----------
                                                              $26,982,208
                                                              ===========

      In connection with the purchase, the Company determined that the

</TABLE>


      At December 31, 1994, no individual security represented more than 10% of
      the total portfolio or 2% of total assets. The Company did not have any
      investments in derivative financial instruments at December 31, 1994.

      In 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. 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.

(5)   CURRENT AND LONG-TERM DEBT

      On March 31, 1995, the Company entered into a loan agreement (the "Loan
      Agreement") with a bank providing for $15 million in senior term
      financing, which was utilized to pay substantially all of the cash portion
      of the Neuromed purchase price and a working capital line of up to $5
      million. 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). The facilities are collateralized by
      certain of the Company's assets, including 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 which collateralize their long-term
      financing described below. The Company is subject to certain covenants
      related to the Loan Agreement including the maintenance of a minimum
      current ratio, ratio of debt to net worth (as defined) and restrictions on
      the payment of cash dividends. During December 1995, the Company repaid in
      its entirety the senior term loan utilizing net proceeds it received from
      a public offering (See Note 11). Borrowings under the working


                                                                     (Continued)

      capital line are due and payable on May 31, 1997. At December 31, 1995,
      the Company had advances in the amount of $4,550,000 outstanding under the
      working capital line with a weighted average interest rate of 7.69%.

      In February 1996, the Company amended the working capital line of credit
      and added a $15 million acquisition line of credit with the same bank.
      Under the amended agreement, the working capital line of credit is
      collateralized by the Company's accounts receivable and inventory and the
      acquisition line, if drawn upon, will be collateralized by the Company's
      remaining unencumbered assets. These facilities will expire on December
      31, 1997 and will bear interest at the prime rate plus 25 basis points or
      LIBOR plus 200 basis points, at the Company's discretion. The interest
      rate can be reduced based on the Company achieving certain ratios of
      senior bank debt to EBITDA. Advances under the acquisition line are
      immediately converted to a five-year term loan. The Company will be
      subject to certain covenants related to these facilities. Significant
      covenants include the maintenance of minimum ratios of current maturities
      coverage ratio, fixed charge ratio and total liabilities to tangible net
      worth ratio (as defined). The Company will also be restricted on the
      payment of cash dividends to 75% of annual net earnings if no draws exist
      under the acquisition line and 25% of annual net earnings if the
      acquisition line has been drawn upon.

      At December 31, 1995, the Company had a note payable in the amount of
      $1,500,000 related to "earn-out" consideration for Neuromed, Inc. (See
      Note 3). The note is due in January 1996 and is non-interest bearing.

      On December 28, 1993, the Company entered into two agreements for
      long-term financing on their principal office and manufacturing facility
      in the amount of $4,355,071. The first agreement, in the amount of
      $3,000,000, is related to the building. This loan bore interest through
      1995 at an adjustable rate based on the 30-day commercial paper rate plus
      300 basis points. Effective January 1996, the Company fixed the rate of
      interest for the remainder of the term of the loan at 8.59%. 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 loan is
      collateralized by the Allen facility building and land and has an unpaid
      balance of $2,966,285 at December 31, 1995. The second agreement, in the
      amount of $1,355,071, is related to certain equipment and furnishings.
      This loan bore interest through 1995 at an adjustable rate based on the
      30-day commercial paper rate plus 250 basis points. Effective January
      1996, the Company fixed the rate of interest for the remainder of the term
      of the loan at 7.94%. This note has a 10-year amortization. This loan is
      collateralized by the equipment and furnishings purchased with the
      proceeds and has an unpaid balance of $1,158,323 at December 31, 1995.

      At December 31, 1995, the Company has 8% and 8.25% note facilities
      available that are collateralized by the Company's marketable securities
      held by investment companies. Borrowings under these notes are restricted
      to 50% of the market value of these securities and at December 31, 1995,
      the amounts available for total borrowings were $249,336 and $196,875,
      respectively. At December 31, 1995, the Company had no advances
      outstanding with respect to these notes.

      Total interest incurred during 1993 was $164,777. Capitalized interest, in
      conjunction with the construction of the principal office and
      manufacturing facility in 1993 was recorded as




                                                                     (Continued)

      part of the building, and is amortized over the assets' useful life. In
      1993, $82,977 of interest costs were capitalized. No interest was
      capitalized in 1995 and 1994.

      The carrying value of the Company's debt approximates its fair value.

      At December 31, 1995 and 1994, $271,767 and $137,927, respectively, of the
      total valuation allowance is attributable to stock option deductions
      which, when realized, will be credited to additional capital. During 1995,
      the valuation allowance decreased by $1,473,323 which was recorded as a
      reduction of costs in excess of net assets acquired because the decrease
      resulted from deferred tax liabilities recorded in connection with the
      acquisition of Neuromed. During 1994, the valuation allowance increased by
      $1,071,356.

      The provision for federal income taxes (benefit) for the years ended
      December 31 consists of the following amounts:

      During 1993, the Company realized $187,236 of tax benefits from stock
      option deductions which were credited to additional capital.

      At December 31, 1995, general business credits of $861,047 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 2010.

(7)   STOCKHOLDERS' EQUITY

      At December 31, 1995 the Company has outstanding stock purchase rights
      attached to each outstanding share of common stock. The rights are not
      exercisable or transferable apart from the common stock until ten days
      after a public announcement that a person or group, with certain
      exceptions, 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. Under the rights
      agreement, the number of shares issuable upon exercise of the rights are
      subject to adjustment by the Company in order to prevent dilution. 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 is
      $12.50. Under certain circumstances described in the rights agreement, the
      holder will be entitled to receive, upon exercise of the right at the
      current exercise price, that number of shares of common stock of the
      Company or acquiring Company having a market value of two times the
      exercise price of the right. 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.

      Pursuant to the 1995 Stock Option Plan ("the 1995 Plan"), officers or
      other employees of the Company or any of its subsidiaries are eligible to
      receive stock option grants. The 1995 Plan provides for the grant of both
      incentive stock options intended to qualify for


                                                                     (Continued)

      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 Plan must equal or exceed the fair market value of the Common Stock
      at the time of the grant. A total of 250,000 shares of Common Stock has
      been reserved for issuance under the 1995 Plan; provided, however, that on
      January 1 of each year (commencing in 1996), the aggregate number of
      shares of Common Stock reserved for issuance under the 1995 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).

      At December 31, 1995, under all of the Company's stock option plans,
      options have been or may be granted to purchase 2,249,892 shares of its
      common stock of which 1,692,257 options have been or may be granted to key
      employees (Employees' Plan and the 1995 Plan) and 557,635 options have
      been or may be granted to directors and advisory directors (Directors'
      Plan). These options are exercisable one-fourth each year over a four-year
      period of continuous service. Certain options under both the Employees'
      Plan and Directors' Plan have a special two (2) year vesting schedule.
      These options are exercisable one-half each year over a two-year period.
      The stock options granted under the Employees' Plan and the 1995 Plan
      expire ten years from the date of grant. The stock options granted under
      the Directors' Plan expire six years from date of grant. The changes in
      the number of common shares issuable under outstanding options, the number
      of shares reserved for issuance and the price range of options for 1995
      and 1994 were as follows:

(8)   COMMITMENTS AND CONTINGENCIES

      The Company has no material commitments under noncancellable operating
      leases. Total rent expense under operating leases for the years ended
      December 31, 1995, 1994, and 1993 was $127,113, $24,930 and $293,221,
      respectively.

      As a consequence of the Neuromed Acquisition in March 1995, the Company is
      currently a party to certain product liability claims related to SCS
      devices sold by Neuromed prior to the acquisition. 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.

      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.

(9)   FINANCIAL INSTRUMENTS, RISK CONCENTRATION, AND MAJOR CUSTOMERS

      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 for trade receivables. The Company maintains an
      allowance for doubtful accounts based upon expected collectibility. 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: 1995 - 10%, 1994 -
      19%, and 1993 - 23%. Foreign sales, primarily in Europe and Australia,
      were approximately 12% of total net revenues for the year ended December
      31, 1995.

(10)     EMPLOYEE BENEFIT PLANS

      The Company has a defined contribution retirement savings plan (the
      "Plan") available to substantially all employees. The Plan permits
      employees to elect salary deferral contributions of up to 15% of their
      compensation and requires the Company to make matching contributions equal
      to 50% of the participants' contributions, to a maximum of 6% of the
      participants' compensation. The expense of the Company's contribution was
      $142,485 in 1995, $102,961 in 1994, and $86,903 in 1993.

(11)     SALE OF COMMON STOCK

      In the fourth quarter of 1995, the Company sold 1,676,667 shares in a
      public offering. Net proceeds to the Company were $15.2 million of which
      $13.9 million was used to repay the senior term bank debt incurred in
      connection with the Neuromed acquisition. Net earnings (loss) per share 
      would have been ($1.28) if this transaction had occurred on March 31, 
      1995, the date at which the debt incurred in connection with the 
      Neuromed acquisition was first outstanding.

unpaid principal due on the fifth anniversary date of such Note. The Facility B
Commitment shall permanently reduce by the amount of each payment required by
this Section 2.7(b) on the date due.

         (c) General. The principal amount of each LIBOR Advance is due and
payable on the last day of the applicable Interest Period, which principal
payment may be made by means of a Refinancing Advance (subject to the other
provisions of this Agreement). On the date of a reduction of the Facility B
Commitment pursuant to Section 2.7(b) and of either Commitment pursuant to
Section 2.8, the aggregate amount of the applicable Advances outstanding on the
date of reduction in excess of such Commitment as reduced shall be due and
payable, which principal payment may not be made by means of a Refinancing
Advance.

         2.8 Reduction of Commitments.

aggregate original face amount of all Facility B Term Notes, effective as of the
date of issue of each Facility B Term Note.

         (b) Optional. Borrower shall have the right at any time and from time
to time upon not less than three Business Days' notice to Lender not later than

termination), to terminate or reduce the Facility A Commitment or Facility B
Commitment, in whole or in part, provided that each partial termination shall be
in an aggregate amount which is an integral multiple of $50,000. Once reduced or
terminated, the Facility A Commitment or Facility B Commitment (as appropriate)
may not be increased or reinstated. On the date of any such reduction, Borrower
shall repay such principal amount (together with accrued interest thereon and
any Consequential Loss) of outstanding Advances as may be necessary so that
after such repayment, the aggregate unpaid principal amount of Advances does not
exceed the amount of the Facility A Commitment or Facility B Commitment (as
appropriate) as then reduced.

interest on the unpaid principal amount of each Advance from the date of such
Advance until such principal shall be paid in full, at the following rates per
annum:

annum equal to the Prime Rate as in effect from time to time.

Advance shall be paid on the last day of the appropriate Interest Period and on

if any Interest Period for a LIBOR Advance exceeds three months, interest shall
also be paid on the date which falls three months after the beginning of such
Interest Period.

         (d) Index. Reference to any particular index or reference rate for
determining any applicable interest rate under this Agreement is for purposes of
calculating the interest due and is not intended as and shall not be construed
as requiring Lender to actually obtain its funds used to make any Advance at any
particular index or reference rate.

Borrower shall pay, on demand, interest (after as well as before judgment to the
extent permitted by Law) on the principal amount of all Advances outstanding and
on all other Obligations due and unpaid hereunder for each Advance equal to the
Highest Lawful Rate.

                  (i) elect to convert, on any Business Day, all or any portion
         of outstanding Prime Advances (in an aggregate amount not less than
         $100,000 or an integral multiple of $100,000 in excess thereof) into
         LIBOR Advances; or

                  (ii) elect to convert, at the end of any Interest Period
         therefor, all or any portion of outstanding LIBOR Advances comprised in
         the same Borrowing (in an aggregate amount not less than $50,000 or an
         integral multiple of $10,000 in excess thereof), into Prime Advances;
         or

                  (iii) elect to continue, at the end of any Interest Period
         therefor, any LIBOR Advances;

         provided, however, that if the aggregate amount of outstanding LIBOR
Advances comprised in the same Borrowing shall have been reduced as a result of
any payment, prepayment or conversion of part thereof to an amount less than
$100,000, the LIBOR Advances comprised in such Borrowing shall automatically
convert into Prime Advances at the end of each respective Interest Period.

         (b) Borrower shall deliver a notice of conversion or continuation (a
"Conversion or Continuation Notice"), in substantially the form of Exhibit J, to
Lender not later than (i) 12:00 noon three Business Days prior to the proposed
date of conversion or continuation, if the Advances or any portion thereof are
to be converted into or continued as LIBOR Advances; and (ii) 10:00 a.m. on the
Business Day of the proposed conversion, if the Advances or any portion thereof
are to be converted into Prime Advances.

         Each such Conversion or Continuation Notice shall be by telecopy or
telex, promptly confirmed by letter, specifying therein:

                  (i) the Note to which the proposed conversion or continuation
         relates;

                  (ii) the proposed date of conversion or continuation;

                  (iii) the aggregate amount of Advances to be converted or
         continued;

                  (iv) the nature of the proposed conversion or continuation;
         and

                  (v) the duration of the applicable Interest Period.

         (c) If, upon the expiration of any Interest Period applicable to LIBOR
Advances, Borrower shall have failed to select a new Interest Period to be
applicable to such 

                                      -23-
<PAGE>   24
LIBOR Advances or if an Event of Default shall then have occurred and be
continuing, Borrower shall be deemed to have elected to convert such LIBOR
Advances into Prime Advances effective as of the expiration date of such current
Interest Period.

         (d) Notwithstanding any other provision contained in this Agreement,
after giving effect to any conversion or continuation of any Advances, there
shall not be outstanding Advances with more than five different Interest
Periods.

         2.12 Maximum Amount of Interest. In no event shall any interest rate
charged hereunder exceed the Highest Lawful Rate. If the amount of interest
payable for the account of Lender on any Quarterly Date in respect of the
immediately preceding interest computation period would exceed the Maximum
Amount, the amount of interest payable on such Quarterly Date shall be
automatically reduced to the Maximum Amount. If the amount of interest payable
for the account of Lender in respect of any interest computation period is
reduced pursuant to the immediately preceding sentence and the amount of
interest payable for its account in respect of any subsequent interest
computation period would be less than the Maximum Amount, then the amount of
interest payable for its account in respect of such subsequent interest
computation period shall be automatically increased to such Maximum Amount;
provided that at no time shall the aggregate amount by which interest paid for
the account of Lender has been increased pursuant to this sentence exceed the
aggregate amount by which interest paid for its account has theretofore been
reduced pursuant to the immediately preceding sentence.

         2.13 Computations. Subject to the provisions of Section 8.12 of this
Agreement, interest on all Advances as well as computation of the Facility A
Commitment Fee and the Facility B Commitment Fee, shall be calculated on the
basis of actual days elapsed, but computed as if each year consisted of 360
days. All LIBOR Advances shall bear interest from and including the first day of
the applicable Interest Period to (but not including) the last day of such
Interest Period. All Prime Advances shall bear interest from and including each
Quarterly Date to (but not including) the next Quarterly Date.

         2.14 Taxes. All payments made by Borrower under this Agreement shall be
made free and clear of and without deduction for or on account of any present or
future income, stamp or other Taxes (excluding, however, Taxes imposed on the
overall net income of Lender or any franchise Taxes).

         2.15 Capital Adequacy; Increased Costs.

         (a) If Lender shall have determined that any change after the Effective
Date in any applicable Law or guideline regarding capital adequacy, capital
maintenance or similar requirements against loan commitments made by Lender
(including any such applicable Law or guideline which may be adopted before the
date of this Agreement but which requirements are phased in over a period of
time), or any change therein, or any change in the interpretation or
administration thereof by any Tribunal, central bank or comparable agency
charged with the 

                                      -24-
<PAGE>   25
interpretation or administration thereof, or compliance by Lender (or any
Lending Office of Lender) or any corporation controlling Lender with any request
or directive regarding capital adequacy, capital maintenance or similar
requirements against loan commitments, whether or not having the force of law
(each such adoptions or modification and each interpretation or administration
being herein called a "Regulatory Modification"), has or would have the effect
of increasing the cost of Lender with respect to this Agreement as a result of
reducing the rate of return on Lender's or such corporation's capital as a
consequence of its obligations hereunder ("Additional Costs") to a level below
that which Lender or such corporation could have achieved but for such adoption,
change or compliance (taking into consideration Lender's or such corporation's
policies with respect to such capital impositions) by an amount deemed by Lender
to be material, then from time to time, Borrower shall pay to Lender such
Additional Costs as will compensate Lender for such reduction. No failure by
Lender to immediately demand payment of Additional Costs payable hereunder shall
constitute a waiver of Lender's right to demand payment of such Additional Costs
at any subsequent time. Determinations by Lender for purposes of this Section
2.15 shall be presumed correct, provided that such determinations are made
reasonably and in good faith. Nothing contained herein shall be construed or so
operate as to require Borrower to pay any interest, fees, costs or charges
greater than as permitted by Applicable Law.

         (b) If, after the date hereof, any Tribunal, central bank or other
comparable authority, shall at any time impose, modify or deem applicable any
reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the account of, or credit extended by, Lender,
or shall impose on Lender other conditions affecting a LIBOR Advance, the Notes,
or its obligation to make a LIBOR Advance; and the result of any of the
foregoing is to increase the cost to Lender of making or maintaining LIBOR
Advances, or to reduce the amount of any sum received or receivable by Lender
under this Agreement or under the Notes by an amount deemed by Lender to be
material, then, within five days after demand by Lender, Borrower shall pay to
Lender the additional amount or amounts as will compensate Lender for the
increased cost or reduction. A certificate of Lender claiming compensation under
this Section 2.15 and setting forth in reasonable detail the calculation of the
additional amount or amounts to be paid to it hereunder shall be conclusive in
the absence of manifest error. If Lender demands compensation under this Section
2.15, Borrower may at any time, upon at least five Business Days' prior notice
to Lender either (i) repay in full the then outstanding principal amount of
LIBOR Advances, together with accrued interest thereon, or (ii) convert such
LIBOR Advances to Prime Advances in accordance with the provisions of this
Agreement; provided, however, that Borrower shall be liable for any
Consequential Loss arising pursuant to such actions.

         (c) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation or administration of
any Law shall make it unlawful, or any central bank or other Tribunal shall
assert that it is unlawful, for Lender to perform its obligations hereunder to
make LIBOR Advances or to continue to fund or maintain LIBOR Advances hereunder,
then, on notice thereof and demand therefor by Lender to Borrower, (i) each
LIBOR Advance will automatically, upon such demand, convert into a Prime Advance
and (ii) the 

                                      -25-
<PAGE>   26
obligation of Lender to make, or to convert into or Continue Advances as, LIBOR
Advances shall be suspended until Lender notifies Borrower that Lender has
determined that the circumstances causing such suspension no longer exist.

         (d) Upon the occurrence and during the continuance of any Default or
Event of Default, (i) each LIBOR Advance will automatically, on the last day of
the then existing Interest Period therefor, convert into a Prime Advance and
(ii) the obligation of Lender to make, or to convert into or Continue Advance
as, LIBOR Advances shall be suspended.

         (e) Failure on the part of Lender to demand compensation for any
increased costs, increased capital or reduction in amounts received or
receivable or reduction in return on capital pursuant to this Section 2.15 with
respect to any period shall not constitute a waiver of Lender's right to demand
compensation with respect to such period or any other period.

         (f) The obligations of Borrower under this Section 2.15 shall survive
any termination of this Agreement; provided that at no time may Lender demand
any compensation under Sections 2.15(a) or (b) for any amount with respect to
any period prior to the date which is six months prior to the date of the notice
or certificate delivered by Lender pursuant to either Section 2.15(a) or (b);
provided further that Lender shall not demand any compensation under Section
2.15(a) or (b) except in accordance with Lender's normal policies for
administering loans with similar provisions.

         (g) Determinations by Lender for purposes of this Section 2.15 shall be
conclusive, absent manifest error. Any certificate delivered to Borrower by
Lender pursuant to this Section 2.15 shall include in reasonable detail the
basis for Lender's demand for additional compensation.

all claims, demands, actions, or causes of action that are asserted by any
Person other than Borrower, its shareholders, directors, officers, agents,

cause of action relates to the Obligations, the use of proceeds of any Advance,
or the relationship of Borrower and Lender under this Agreement or any
transaction contemplated pursuant to this Agreement or any other Loan Paper, (b)
any proceeding or any administrative, investigative or arbitration proceeding by
or before any Tribunal or arbitral directly or indirectly related to (i) a
claim, 

                                      -34-
<PAGE>   35
demand, action or cause of action described in clause (a) above or (ii) any
claim, demand, proceeding, action or cause of action involving Borrower or any
Affiliate (including any shareholder) of Borrower in which any Indemnitee incurs
costs and expenses as a result of any requirement that such Indemnitee testify
or produce records therein (other than as a result of any Litigation commenced

party), and (c) any and all liabilities, losses, costs, or expenses (including

prevailing party); provided, however, that Borrower shall not have any
obligation under this Section 4.13 to a particular Indemnitee or with respect to
any of the foregoing arising out of the negligence or willful misconduct of such
Indemnitee. If any claim, demand, action or cause of action is asserted against
any Indemnitee, such Indemnitee shall promptly notify Borrower, but the failure
to so promptly notify Borrower shall not affect Borrower's obligations under
this Section 4.13 except to the extent such failure materially impairs
Borrower's ability to defend any such claim, demand, action or cause of action.
Any obligation or liability of Borrower to any Indemnitee under this Section
4.13 shall survive the expiration or termination of this Agreement and the
repayment of the Obligation.

be used, directly or indirectly, for the purpose, whether immediate, incidental
or ultimate, of purchasing or carrying any margin stock or for the purpose of
maintaining, reducing or retiring any indebtedness which was originally incurred
to purchase or carry any stock that is currently a margin stock or for any other
purpose which might constitute this transaction a "purpose credit" within the
meaning of such Regulation G. Neither Borrower nor any agent acting on its

regulation of the Board of Governors of the Federal Reserve System or to violate

is or would be materially adverse to Borrower.

         6.12 Disclosure. Neither this Agreement or any other document,
certificate or statement furnished, or to be furnished, to Lender by or on
behalf of Borrower or any other Obligor in connection herewith or therewith

have complied with all federal, state, local and regional statutes, ordinances,
orders, judgments, rulings and regulations relating to any matters of pollution
or of environmental regulation or control except, in any such case, where such
failure to comply would not result in a Material Adverse Effect. Without
limiting the generality of the preceding sentence, neither Borrower nor any
Subsidiary of Borrower has received notice of and does not have actual knowledge
of any actual or claimed or asserted failure so to comply which alone or
together with any other such failure is material and would result in a 

                                      -40-
<PAGE>   41
Material Adverse Effect. During periods of use, ownership, occupancy or

Environmental Response Compensation and Liability Act, the Hazardous Materials
Transportation Act, the Toxic Substance Control Act, the Clean Air Act and the
Clean Water Act, in material violation of or in a manner which would result in
liability under such statutes or any regulations promulgated pursuant thereto or
any other applicable law, except where such noncompliance or liability would not
result in a Material Adverse Effect.

Obligation incurred and Liens created by Borrower and each Subsidiary of

         (j) Any Inventory of Borrower or any Subsidiary of Borrower produced in

write down is the value of such Inventory) of all Inventory of Borrower or such
Subsidiary, respectively; or

         (k) Any material provision of the Loan Papers shall at any time for any

accelerate, or notice of any other kind, all of which are hereby expressly
waived. Should any other Event of Default occur and be continuing, Lender may do
any one or more of the following:

         (a) Acceleration. Declare the entire unpaid balance of the Obligation,
or any part thereof, immediately due and payable, whereupon it shall be due and
payable without any action by Lender and without diligence, presentment, demand,

all of which are hereby expressly waived.

         (b) Termination. Terminate the Facility A Commitment and the Facility B
Commitment.

<PAGE>   44
         (e) Offset. Exercise the Rights of offset and/or banker's Lien against
the interest of Borrower and each other Obligor in and to every account and
other property of Borrower and each other Obligor which is in the possession of
Lender, to the extent of the full amount of the Obligation.

         7.3 Performance by Lender. Should any covenant, duty or agreement of
Borrower fail to be performed in all material respects in accordance with the
terms of this Agreement or the Collateral Documents, Lender may, at its option,
perform, or attempt to perform, such covenant, duty or agreement on behalf of
Borrower. In such event, Borrower shall, at the request of Lender, promptly pay
any amount expended by Lender in such performance or attempted performance to
Lender at Lender's Principal Office, together with interest thereon at the
lesser of (a) the Prime Rate plus 3% and (b) the Highest Lawful Rate from the
date of such expenditure by Lender until paid. Notwithstanding the foregoing, it
is expressly understood that Lender shall not have any liability or
responsibility for the performance of any duties of Borrower hereunder.

         7.4 Lender Not in Control. None of the covenants or other provisions
contained in this Agreement shall, or shall be deemed to, give Lender the Rights
or power to exercise control over the affairs management of Borrower, the power
of Lender being limited to the Right to exercise the remedies provided in this
Article VII; provided that, if Lender becomes the owner of any interest in
Borrower, whether through foreclosure or otherwise, Lender shall be entitled to
exercise such legal Rights as it may have by being an owner of such interest in
Borrower.

         7.5 Waivers. The acceptance by Lender at any time and from time to time
of part payment on the Obligation shall not be deemed to be a waiver of any
Event of Default or Default then existing. No waiver by Lender of any particular
Event of Default or Default shall be deemed to be a waiver of any Event of
Default or Default other than said particular Event of Default or Default. No
delay or omission by Lender in exercising any Right under any Loan Papers shall
impair such Right or be construed as a waiver thereof or an acquiescence
therein, nor shall any single or partial exercise of any such Right preclude
other or further exercise thereof, or the exercise of any other Right under the
Loan Papers or otherwise.

         7.6 Cumulative Rights. All Rights available to Lender under the Loan
Papers shall be cumulative of and in addition to all other Rights granted to
Lender at Law or in equity, whether or not the Obligation be due and payable and
whether or not Lender shall have instituted any suit for collection or other
action in connection with any Loan Paper.

         7.7 Expenditures by Lender. Any sums, including reasonable attorneys'
fees, spent by Lender pursuant to the exercise of any Right provided in this
Article VII shall become part of the Obligation and shall bear interest at a
rate per annum equal to the lesser of (a) the Prime Rate plus 3% and (b) the
Highest Lawful Rate from the date spent until the date repaid by Borrower.

         8.9 Governing Law. This Agreement and all other Loan Papers shall be
deemed contracts made under the Laws of Texas and shall be construed and
enforced in accordance with and governed by the Laws of Texas, except to the
extent federal Laws govern the validity, construction, enforcement and

agree that the provisions of Art. 5069-15.01 et seq. of the Revised Civil

         8.10 MANDATORY ARBITRATION. (A) ANY CONTROVERSY OR CLAIM BETWEEN OR
AMONG THE PARTIES HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY RELATED AGREEMENTS OR INSTRUMENTS, INCLUDING
ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT, SHALL BE DETERMINED BY
BINDING ARBITRATION IN ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (OR IF NOT
APPLICABLE, THE APPLICABLE STATE LAW), THE RULES OF PRACTICE AND PROCEDURE FOR
THE ARBITRATION OF COMMERCIAL DISPUTES OF JUDICIAL ARBITRATION AND MEDIATION
SERVICES, INC. ("JAMS"), AND THE "SPECIAL RULES" SET FORTH BELOW. IN THE EVENT
OF ANY INCONSISTENCY, THE SPECIAL RULES SHALL CONTROL. JUDGMENT UPON ANY
ARBITRATION AWARD MAY BE ENTERED IN ANY COURT HAVING JURISDICTION. ANY PARTY TO
THIS AGREEMENT MAY BRING AN ACTION, INCLUDING A SUMMARY OR EXPEDITED PROCEEDING,
TO COMPEL ARBITRATION OF ANY CONTROVERSY 

                                      -47-
<PAGE>   48
OR CLAIM TO WHICH THIS AGREEMENT APPLIES IN ANY COURT HAVING JURISDICTION OVER
SUCH ACTION.

         (b) Special Rules. The arbitration shall be conducted in Dallas, Texas
and administered by JAMS who will appoint an arbitrator; if JAMS is unable or
legally precluded from administering the arbitration, then the American
Arbitration Association will serve. All arbitration hearings will be commenced
within ninety days of the demand for arbitration; further, the arbitrator shall
only, upon a showing of cause, be permitted to extend the commencement of such
hearing for up to an additional sixty days.

         (c) Reservations of Rights. Nothing in this Agreement or any other Loan
Paper shall be deemed to (i) limit the applicability of any otherwise applicable
statutes of limitation or repose and any waivers contained in this Agreement; or
(ii) be a waiver by Lender of the protection afforded to it by 12 U.S.C. Section
91 or any substantially equivalent state law; or (iii) limit the right of Lender
hereto (A) to exercise self help remedies such as (but not limited to) setoff,
or (B) to foreclose against any real or personal property collateral, or (C) to
obtain from a court provisional or ancillary remedies such as (but not limited
to) injunctive relief or the appointment of a receiver. Lender may exercise such
self help rights, foreclose upon such property, or obtain such provisional or
ancillary remedies before, during or after the pendency of any arbitration
proceeding brought pursuant to this Agreement. At Lender's option, foreclosure
under a deed of trust or mortgage may be accomplished by any of the following:
the exercise of a power of sale under the deed of trust or mortgage, or by
judicial sale under the deed of trust or mortgage, or by judicial foreclosure.
Neither this exercise of self help remedies nor the institution or maintenance
of an action for foreclosure or provisional or ancillary remedies shall
constitute a waiver of the right of any party, including the claimant in any
such action, to arbitrate the merits of the controversy or claim occasioning
resort to such remedies.

         8.11 WAIVER OF JURY TRIAL. TO THE MAXIMUM EXTENT PERMITTED BY LAW,
BORROWER HEREBY WAIVES ANY RIGHT THAT IT MAY HAVE TO A TRIAL BY JURY OF ANY
DISPUTE (WHETHER A CLAIM IN TORT, CONTRACT, EQUITY, OR OTHERWISE) ARISING UNDER
OR RELATING TO THIS AGREEMENT, THE OTHER LOAN PAPERS, OR ANY RELATED MATTERS,
AND AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A
JURY.

         8.12 Maximum Amount Limitation. It is not the intention of any of the
parties to this Agreement to make an agreement violative of the Laws of any
applicable jurisdiction relating to usury. Regardless of any provision in this
Agreement, the Notes or any other Loan Paper, Lender shall never be entitled to
receive, collect or apply, as interest on the Obligation, any amount in excess
of the Maximum Amount. If Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall
be deemed a partial repayment of principal and treated hereunder as such; and if
principal is paid in full, any remaining excess shall be paid to Borrower. In
determining whether or not the interest paid or payable, under any specific
contingency, exceeds the Maximum Amount, Borrower and Lender shall, to the

                                       -48-
<PAGE>   49
maximum extent permitted under Applicable Laws, (a) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest, (b)
exclude voluntary prepayments and the effect thereof, and (c) amortize, prorate,
allocate and spread in equal parts, the total amount of interest throughout the
entire contemplated term of the Obligation so that the interest rate is uniform
throughout the entire term of the Obligation; provided that if the Obligation is
paid and performed in full prior to the end of the full contemplated term
thereof, and if the interest received for the actual period of existence thereof
exceeds the Maximum Amount, Lender shall refund to Borrower the amount of such
excess or credit the amount of such excess against the total principal amount
owing, and, in such event, Lender shall not be subject to any penalties provided
by any Laws for contracting for, charging or receiving interest in excess of the
Maximum Amount. This Section 8.12 shall control every other provision of all
agreements among the parties to this Agreement pertaining to the transactions
contemplated by or contained in the Notes and the other Loan Papers.

         8.13 Severability. If any provision of this Agreement or any other Loan
Paper is held to be illegal, invalid or unenforceable under present or future
Laws during the term thereof, such provision shall be fully severable, the
appropriate agreement or instrument shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part thereof,
and the remaining provisions thereof shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance therefrom. Furthermore, in lieu of such illegal, invalid or
unenforceable provision there shall be added automatically as a part of such
agreement or instrument a provision as similar in terms to the illegal, invalid
or unenforceable provision as may be possible and legal, valid and enforceable.

         8.14 Amendment. The provisions of this Agreement and each other Loan
Paper may not be amended, modified or waived except by the written agreement of
Borrower and Lender. This Agreement embodies the entire agreement among the
parties, supersedes all prior agreements and understandings, if any, relating to
the subject matter hereof, and may be amended only as provided above.

         8.15 Exceptions to Covenants. Borrower shall not be deemed to be
permitted to take any action or fail to take any action which is permitted as an
exception to any of the covenants contained herein or which is within the
permissible limits of any of the covenants contained herein if such action or
omission would result in the breach of any other covenant contained herein.

         8.16 Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument, but in making proof of this Agreement, it shall not be necessary to
produce or account for more than one such counterpart.

         8.17 Restatement. This Agreement restates in its entirety the First
Restated Credit Agreement. All obligations of each Obligor pursuant to the First
Restated Credit Agreement are amended and restated by this Agreement, which is
not intended as a release or novation of any such obligation.

         8.18 ENTIRE AGREEMENT. THIS AGREEMENT AND THE LOAN PAPERS REPRESENT THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY (A) EVIDENCE
OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES, OR (B)
THE COMMITMENT LETTER, DATED SEPTEMBER 25, 1995 FROM LENDER TO BORROWER (ALL THE
TERMS AND CONDITIONS OF WHICH ARE SUPERSEDED BY THE LOAN PAPERS). THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of the day and year first above written.

                                (Facility A Note)

$5,000,000.00                     Dallas, Texas                February 9, 1996


         QUEST MEDICAL, INC., a Texas corporation, with its principal office
located at One Allentown Parkway, Allen, Texas 75002 ("Borrower"), for value
received, promises to pay to the order of NATIONSBANK OF TEXAS, N.A. ("Lender"),
at its Dallas Banking Center at 901 Main Street, Dallas, Texas 75202, in
immediately available funds and in lawful money of the United States of America,
the principal sum of Five Million and 00/100 Dollars ($5,000,000.00), or such
lesser sum as shall be due and payable from time to time hereunder, on December
31, 1997, or sooner, as provided in the Credit Agreement referred to below.
Borrower promises to pay interest on the unpaid principal amount of the Facility
A Advances (as defined in the Credit Agreement) from the date made until such
principal amount is paid in full, at such interest rates, and payable at such
times, as are specified in the Credit Agreement.

         For the purposes of this Note, the following terms have the respective
meanings assigned to them below:

                  "Applicable Law" means the laws of the United States of
         America applicable to contracts made or performed in the State of
         Texas, including, without limitation, 12 USC 86, as amended to the date
         hereof and as the same may be amended at any time and from time to time
         hereafter and any other statute of the United States of America now or
         at any time hereafter prescribing maximum rates of interest on loans
         and extensions of credit, and the laws of the State of Texas,
         including, without limitation, Article 1.04, Title 79, Revised Civil
         Statutes of Texas, 1925, as the same may be amended at any time and
         from time to time hereafter ("Article 1.04") and any other statute of
         the State of Texas now or at any time hereafter prescribing maximum
         rates of interest on loans and extensions of credit provided that
         pursuant to Article 5069-15.10(b), Title 79, Revised Civil Statues,
         1925, as amended, Borrower agrees that the provisions of Chapter 15,
         Title 79, Revised Civil Statutes of Texas, 1925, as amended, shall not
         apply to this Note.

                  "Highest Lawful Rate" means at the particular time in question
         the maximum rate of interest which, under Applicable Law, Lender is
         then permitted to charge on the obligation hereunder. If the maximum
         rate of interest which, under Applicable Law, Lender is permitted to
         charge on the obligation hereunder shall change after the date hereof,
         the Highest Lawful Rate shall be automatically increased or decreased,
         as the case may be, from time to time as of the effective time of each
         change in the Highest Lawful Rate without notice to Borrower. For
         purposes of determining the Highest Lawful Rate under the Applicable
         Law of the State of Texas, the applicable rate ceiling shall be (i) the
         indicated rate ceiling described in and computed in accordance with the
         provisions of Section (a)(1) of Article 1.04, Title 79, Revised Civil
         Statues of Texas 1925, as amended, or (ii) if the parties subsequently
         contract as allowed by Applicable Law, the quarterly ceiling or the
         annualized 
<PAGE>   2
         ceiling computed pursuant to Section (d) of said Article 1.04;
         provided, however, that if at any time the indicated rate ceiling, the
         quarterly ceiling or the annualized ceiling, as applicable, shall be
         less than 18% per annum or more than 24% per annum, the provisions of
         Sections (b)(1) and (2) of said Article 1.04 shall control for purposes
         of such determination, as applicable.

         Notwithstanding the foregoing and all other provisions of this Note and
any documents and instruments executed in connection with this Note, in no event
shall the interest payable hereon, whether before or after maturity, exceed the
Highest Lawful Rate of interest which, under Applicable Law, Lender is permitted
to charge to Borrower.

         All agreements between Borrower and Lender, or any subsequent holder of
this Note, whether now existing or hereafter arising and whether written or
oral, are expressly limited so that in no contingency or event whatsoever,
whether by reason of acceleration of the maturity of this Note or otherwise,
shall the amount paid or agreed to be paid to the holder of this Note for the
use, forbearance, or detention of the funds advanced pursuant to this Note or
for the performance or payment of any covenant or obligation contained herein or
in any other document evidencing, securing or pertaining to this Note, exceed
the maximum amount permissible under Applicable Law. If from any circumstance
whatsoever fulfillment of any provision hereof or of any such other document, at
the time performance of such provision shall be due, shall involve transcending
the limit of validity prescribed by Applicable Law, then ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstance the holder hereof shall ever receive anything of value
deemed excess interest by Applicable Law, an amount equal to any such excess
interest shall be applied to the reduction of the principal amount owing under
this Note, and not to the payment of interest, or if such excess interest
exceeds the unpaid principal balance of this Note, such excess interest shall be
refunded to Borrower. All sums paid or agreed to be paid to any holder of this
Note for the use, forbearance or detention of any funds advanced pursuant to
this Note shall, to the extent permitted by Applicable Law, be amortized,
prorated, allocated and spread throughout the full term of this Note until
payment in full so that the rate of interest on account of the indebtedness
evidenced by this Note is uniform throughout the term hereof. The terms and
provisions of this paragraph shall control and supersede every other provision
of all agreements between Borrower and any holder of this Note.

         This Note is issued pursuant to the Second Amended and Restated Credit
Agreement between Borrower and Lender dated as of February 9, 1996 (such
agreement, together with all amendments and restatements, the "Credit
Agreement"), to which reference is made for a statement of the rights and
obligations of Lender and the duties and obligations of Borrower in relation
thereto; but neither this reference to the Credit Agreement nor any provision
thereof shall affect or impair the absolute and unconditional obligation of
Borrower to pay unpaid principal of and interest on this Note when due. The
Credit Agreement among other things, contains provisions for acceleration of the
maturity hereof upon the happening of certain stated events and also for
prepayments on account of principal hereof prior to the maturity hereof upon the
terms and conditions therein specified. If a breach of or default under the
Credit Agreement or any other Loan Paper (as defined in the Credit Agreement)

                                       -2-
<PAGE>   3
shall occur, unpaid principal of and interest on this Note may be declared due
and payable without notice, at the option of the holder of this Note, in the
manner and with the effect provided thereunder. Failure to exercise this option
shall not constitute a waiver of the right to exercise the same in the event of
any subsequent default or event of default. This Note is a renewal and
restatement of the promissory note (Facility A Note) dated March 31, 1995 made
by Borrower and payable to the order of Lender in the principal amount of
$5,000,000.00, and is not a novation or impairment of such note.

         If this Note is placed in the hands of an attorney for collection after
default, or if all or any part of the indebtedness represented hereby is proved,
established or collected in any court or in any bankruptcy, receivership, debtor
relief, probate or other court proceedings, Borrower and all endorsers, sureties
and guarantors of this Note jointly and severally agree to pay reasonable
attorneys' fees and collection costs to the holder hereof in addition to the
principal and interest payable hereunder.

         Borrower and all endorsers, sureties and guarantors of this Note hereby
severally waive demand, presentment for payment, protest, notice of protest,
notice of acceleration of and notice of intention to accelerate the maturity of
this Note, diligence in collecting, the bringing of any suit against any party

before or after maturity.

         THIS NOTE AND THE RIGHTS AND DUTIES OF THE PARTIES HEREUNDER SHALL BE
GOVERNED BY THE LAWS OF THE STATE OF TEXAS, EXCEPT TO THE EXTENT THE SAME ARE
GOVERNED BY THE FEDERAL LAWS OF THE UNITED STATES OF AMERICA APPLICABLE TO
NATIONAL BANKS. THE BOOKS AND RECORDS OF LENDER SHALL CONSTITUTE PRIMA FACIE

                            (Facility B Advance Note)

$15,000,000.00                    Dallas, Texas                February 9, 1996


         QUEST MEDICAL, INC., a Texas corporation, with its principal office
located at One Allentown Parkway, Allen, Texas 75002 ("Borrower"), for value
received, promises to pay to the order of NATIONSBANK OF TEXAS, N.A. ("Lender"),
at its Dallas Banking Center at 901 Main Street, Dallas, Texas 75202, in
immediately available funds and in lawful money of the United States of America,
the principal sum of Fifteen Million and 00/100 Dollars ($15,000,000.00), or
such lesser sum as shall be due and payable from time to time hereunder, on
December 31, 1997, or sooner, as provided in the Credit Agreement referred to
below. Borrower promises to pay interest on the unpaid principal amount of the
Facility B Advances (as defined in the Credit Agreement) from the date made
until such principal amount is paid in full, at such interest rates, and payable
at such times, as are specified in the Credit Agreement.

         For the purposes of this Note, the following terms have the respective
meanings assigned to them below:

                  "Applicable Law" means the laws of the United States of
         America applicable to contracts made or performed in the State of
         Texas, including, without limitation, 12 USC 86, as amended to the date
         hereof and as the same may be amended at any time and from time to time
         hereafter and any other statute of the United States of America now or
         at any time hereafter prescribing maximum rates of interest on loans
         and extensions of credit, and the laws of the State of Texas,
         including, without limitation, Article 1.04, Title 79, Revised Civil
         Statutes of Texas, 1925, as the same may be amended at any time and
         from time to time hereafter ("Article 1.04") and any other statute of
         the State of Texas now or at any time hereafter prescribing maximum
         rates of interest on loans and extensions of credit provided that
         pursuant to Article 5069-15.10(b), Title 79, Revised Civil Statues,
         1925, as amended, Borrower agrees that the provisions of Chapter 15,
         Title 79, Revised Civil Statutes of Texas, 1925, as amended, shall not
         apply to this Note.

                  "Highest Lawful Rate" means at the particular time in question
         the maximum rate of interest which, under Applicable Law, Lender is
         then permitted to charge on the obligation hereunder. If the maximum
         rate of interest which, under Applicable Law, Lender is permitted to
         charge on the obligation hereunder shall change after the date hereof,
         the Highest Lawful Rate shall be automatically increased or decreased,
         as the case may be, from time to time as of the effective time of each
         change in the Highest Lawful Rate without notice to Borrower. For
         purposes of determining the Highest Lawful Rate under the Applicable
         Law of the State of Texas, the applicable rate ceiling shall be (i) the
         indicated rate ceiling described in and computed in accordance with the
         provisions of Section (a)(1) of Article 1.04, Title 79, Revised Civil
         Statues of Texas 1925, as amended, or (ii) if the parties subsequently
         contract as allowed by Applicable Law, the quarterly 
<PAGE>   2
         ceiling or the annualized ceiling computed pursuant to Section (d) of
         said Article 1.04; provided, however, that if at any time the indicated
         rate ceiling, the quarterly ceiling or the annualized ceiling, as
         applicable, shall be less than 18% per annum or more than 24% per
         annum, the provisions of Sections (b)(1) and (2) of said Article 1.04
         shall control for purposes of such determination, as applicable.

         Notwithstanding the foregoing and all other provisions of this Note and
any documents and instruments executed in connection with this Note, in no event
shall the interest payable hereon, whether before or after maturity, exceed the
Highest Lawful Rate of interest which, under Applicable Law, Lender is permitted
to charge to Borrower.

         All agreements between Borrower and Lender, or any subsequent holder of
this Note, whether now existing or hereafter arising and whether written or
oral, are expressly limited so that in no contingency or event whatsoever,
whether by reason of acceleration of the maturity of this Note or otherwise,
shall the amount paid or agreed to be paid to the holder of this Note for the
use, forbearance, or detention of the funds advanced pursuant to this Note or
for the performance or payment of any covenant or obligation contained herein or
in any other document evidencing, securing or pertaining to this Note, exceed
the maximum amount permissible under Applicable Law. If from any circumstance
whatsoever fulfillment of any provision hereof or of any such other document, at
the time performance of such provision shall be due, shall involve transcending
the limit of validity prescribed by Applicable Law, then ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstance the holder hereof shall ever receive anything of value
deemed excess interest by Applicable Law, an amount equal to any such excess
interest shall be applied to the reduction of the principal amount owing under
this Note, and not to the payment of interest, or if such excess interest
exceeds the unpaid principal balance of this Note, such excess interest shall be
refunded to Borrower. All sums paid or agreed to be paid to any holder of this
Note for the use, forbearance or detention of any funds advanced pursuant to
this Note shall, to the extent permitted by Applicable Law, be amortized,
prorated, allocated and spread throughout the full term of this Note until
payment in full so that the rate of interest on account of the indebtedness
evidenced by this Note is uniform throughout the term hereof. The terms and
provisions of this paragraph shall control and supersede every other provision
of all agreements between Borrower and any holder of this Note.

         This Note is issued pursuant to the Second Amended and Restated Credit
Agreement between Borrower and Lender dated as of February 9, 1996 (such
agreement, together with all amendments and restatements, the "Credit
Agreement"), to which reference is made for a statement of the rights and
obligations of Lender and the duties and obligations of Borrower in relation
thereto; but neither this reference to the Credit Agreement nor any provision
thereof shall affect or impair the absolute and unconditional obligation of
Borrower to pay unpaid principal of and interest on this Note when due. The
Credit Agreement among other things, contains provisions for acceleration of the
maturity hereof upon the happening of certain stated events and also for
prepayments on account of principal hereof prior to the maturity hereof upon the
terms and conditions therein specified. If a breach of or default under the
Credit Agreement 


                                       -2-
<PAGE>   3
or any other Loan Paper (as defined in the Credit Agreement) shall occur, unpaid
principal of and interest on this Note may be declared due and payable without
notice, at the option of the holder of this Note, in the manner and with the
effect provided thereunder. Failure to exercise this option shall not constitute
a waiver of the right to exercise the same in the event of any subsequent
default or event of default. This Note is a renewal and restatement of the
promissory note (Facility B Note) dated March 31, 1995 made by Borrower and
payable to the order of Lender in the principal amount of $15,000,000.00, and is
not a novation or impairment of such note.

         If this Note is placed in the hands of an attorney for collection after
default, or if all or any part of the indebtedness represented hereby is proved,
established or collected in any court or in any bankruptcy, receivership, debtor
relief, probate or other court proceedings, Borrower and all endorsers, sureties
and guarantors of this Note jointly and severally agree to pay reasonable
attorneys' fees and collection costs to the holder hereof in addition to the
principal and interest payable hereunder.

         Borrower and all endorsers, sureties and guarantors of this Note hereby
severally waive demand, presentment for payment, protest, notice of protest,
notice of acceleration of and notice of intention to accelerate the maturity of
this Note, diligence in collecting, the bringing of any suit against any party
and any notice of or defense on account of any extensions, renewals, partial
payments or changes in any manner of or in this Note or in any of its terms,
provisions and covenants, or any releases or substitutions of any security, or
any delay, indulgence or other act of any trustee or any holder hereof, whether
before or after maturity.

GOVERNED BY THE FEDERAL LAWS OF THE UNITED STATES OF AMERICA APPLICABLE TO
