Item 1.           Business.
                  ---------

GENERAL

          Merit  Medical  Systems,  Inc. (the  "Company")  was formed in 1987 by
members  of its  current  management  for the  purpose of  producing  single use
medical  products  of high  quality  and  superior  value  primarily  for use in
diagnosis and treatment of cardiovascular  disease.  The Company's  products are
designed to provide  physicians and other health care professionals with devices
that enable them to perform  interventional and diagnostic procedures safely and
effectively. Initially, the Company's expertise in innovative product design and
its proprietary technology and skills in injection and insert molding enabled it
to introduce  innovative new products and capture  significant market share. The
Company   subsequently   combined  its  plastics  molding  capability  with  the
application of proprietary electronics and sensor-based  technologies to develop
a line of angioplasty  inflation  products with  electronic  sensing and display
features.  These devices are now included in a series of  sensor-based  products
that address a broad range of needs  related to  diagnostic  and  interventional
catheterization procedures performed in hospitals.

          The  Company's  strategy  is to  offer  a broad  line  of  innovative,
disposable  products for use in angiography,  angioplasty and similar procedures
and to increase market  acceptance and penetration for both its existing and new
products in the U.S. and in  international  markets.  Longer term, the Company's
strategy is to extend the  application of its plastics  molding,  electronic and
sensor-based  technologies to develop products for diagnostic and interventional
procedures in additional  markets such as  neuroradiology,  urology and critical
care.  The Company's  sales of products in  combination  and in custom kits have
increased as additions have been made to the Company's  product lines.  In 1997,
approximately  60% of the Company's  sales were made directly to U.S.  hospitals
and approximately 17% of sales were made to custom packagers who also distribute
to U.S. hospitals. Approximately 23% of the Company's sales in 1997 were made in
international markets.

          The Company was organized in July 1987 as a Utah corporation.  In July
1994,  the  Company   purchased   controlling   interest  in  Sentir,   Inc.,  a
California-based manufacturer of silicon sensors. The Company has also organized
subsidiaries in Ireland,  Germany, France, the United Kingdom,  Belgium, and the
Netherlands  to conduct its  international  business.  On January 31, 1997,  the
Company  purchased the operating  assets and product lines of Universal  Medical
Instrument  Corp.("UMI").  The Company also leased from UMI a 32,000 square foot


                                        1





facility in Saratoga  Springs,  New York.  The Company's  principal  offices are
located in a manufacturing and office facility at 1600 West Merit Parkway, South
Jordan,  Utah 84095,  and its telephone  number is (801) 253-1600.  See "Item 2.
Properties."

PRODUCTS

          The Company's products have been designed and developed in response to
the needs of customers and patients.  These needs have been identified primarily
through observation of procedures in the cardiac  catheterization  laboratories,
consultation  with  the  Company's  cardiologist  advisors  and  through  direct
communication  with  customers.  Since  1988,  the  Company  has  developed  and
introduced  several product lines,  including control syringes  ("CCS"and "Smart
Tip"),  inflation devices  ("Intellisystem,"  "Monarch," and " Basix," including
new  25-atmosphere  versions of the  Intellisystem,  Monarch and Basix devices),
specialty  syringes  ("Medallion"  and  "VacLoc"),   high  pressure  tubing  and
connectors  ("Sherlock") , waste handling and disposal products ("Merit Disposal
Depot" and "Backstop"),  a disposable blood pressure  transducer  ("Meritrans"),
disposable  hemostasis  valves ("Passage" and "Access-9"),  stopcocks  ("Marquis
Series") a torque device ("Scout") and contrast  management systems ("Miser" and
"In-line Contrast Management System"). These products are sold separately and in
custom kits consisting primarily of selected combinations of products.

          On January 31, 1997, Merit Medical acquired four new product lines and
technologies from UMI (needles,  guide wires, sheath introducers and catheters).
During  January  1997,  the Company began  marketing a new line of  angiographic
needles through its direct sales organization world wide. The Company's strategy
is to combine  these newly  acquired  technologies  and product  platforms  with
Merit's  existing  products  and sales  force to address  larger  markets and to
expand sales to existing customers.

          The Company has not experienced any product liability claims; however,
the sale and use of its products entails an inherent risk that product liability
claims may be  asserted  against the  Company.  The  Company  maintains  product
liability  insurance  in the  amount of  $5,000,000  per  occurrence  and in the
aggregate,  which may not be  adequate  for  expenses  or  liabilities  actually
incurred.

          Inflation Devices.  Inflation devices are specialized syringes used in
interventional  catheterization procedures to inflate and deflate balloon-tipped
catheters.  Each of the Company's  inflation  devices  incorporates  proprietary
design  features  which  contribute  to  ease  of use,  including  allowing  the
cardiologist  or radiologist  to engage or release the syringe  plunger with one
hand while  increasing or decreasing the pressure.  Each syringe also provides a
clear view of the fluid  path that  simplifies  debubbling  and  contributes  to
accurate  measurement  of  balloon  pressure.   The  Company  recently  received
marketing  clearance  for use of it's  inflation  devices  for a wide  range  of
additional  clinical  applications  such as esophageal  dilation,  compartmental
compression, retinal detachment and discography.

          The Company's IntelliSystem inflation device, which was the first such
device to incorporate  electronic  sensing and display  features,  consists of a
disposable  20cc inflation  syringe and an integral  pressure  transducer  which
connects  to an  electronic  monitor  outside of the sterile  field.  To aid the
marketing  process and encourage use of the Company's  products,  the electronic
monitor is provided  without charge to customers  using the  IntelliSystem.  The
IntelliSystem  measures,  times,  records  and  digitally  displays  information
concerning the pressure,  duration and number of each inflation and deflation of
the  angioplasty  balloon.  The Company  believes  that  electronic  sensing and
display  of such  information  is much more  accurate  and  precise  than can be
obtained  from  conventional  analog  gauges.  The  data  is  stored  and may be
displayed, retrieved, graphed and printed.

           The Monarch is a disposable inflation device which digitally displays
data  concerning  pressure and duration of inflations  and deflations on a small
electronic monitor mounted on the barrel of the inflation  syringe.  The monitor
does not offer all of the  display,  storage  or  printing  capabilities  of the
IntelliSystem but offers the convenience of portable operation.

           The Basix is a  disposable  inflation  device  which  incorporates  a
conventional  analog  pressure  gauge,  which is  mounted  on the  barrel of the
inflation  syringe.  The Basix more closely  resembles  devices  marketed by the
Company's competitors but incorporates the Company's proprietary design features


                                        2





and  benefits.  The Company  believes  that the Basix  represents a  significant
addition to its line of inflation  devices that will  contribute  to sales where
cost considerations are important, such as in certain international markets.

          In January 1996, the Company began shipping  25-atmosphere versions of
the  Intellisystem,  Monarch and Basix  devices in response to market demand for
devices  capable  of  performing  at  higher  pressures,  such as in  procedures
involving the placement of stents.

          Control  Syringes.  The  Company's  disposable  control  syringes  are
utilized for  one-handed  control of the  injection of contrast  media and other
fluids during angiography and angioplasty  procedures.  The control syringes are
molded  from  polycarbonate  material  which is  stronger  than  glass and other
plastics used in the industry.  The Company offers different models and sizes of
the control syringes with varying features which respond  primarily to physician
preferences.  These features include different configurations of syringe handles
and plungers and connections  which allow operation of the syringe in a fixed or
rotating position.  In 1997, Merit introduced a new line of high quality control
syringes with a very sensitive low resistance plunger tip ("Smart Tip").

          Custom  Kits.  Custom  kits allow  physicians  to obtain  the  medical
devices  and  accessories  that they most  frequently  use  during  angiography,
angioplasty and similar procedures in a convenient, prepackaged and preassembled
form.  Custom kits also provide cost savings over purchasing single products and
reduce the  hospital's  administrative  costs  associated  with  maintaining  an
inventory of individual, sterile products.

          Specialty Syringes.  Merit's Medallion syringes, a line of disposable,
color coded specialty  syringes are used for injection of medications,  flushing
of  manifolds  and  other  general  purposes.   These  syringes  are  molded  of
polycarbonate material for added strength and are available in hundreds of size,
color and custom printing  combinations.  The color coding allows a clinician to
assign a color for each medication to be dispensed and to differentiate syringes
by their contents. The syringes can also be custom printed to the specifications
of the user.  In response to customer  requests,  the Company has  developed and
added  additional  sizes of its specialty  syringes which have  applications  in
dispensing  various  medication  required  in  a  broader  range  of  peripheral
procedures.  The Company  believes  that the design,  color coding and materials
used in its specialty  syringes  contribute to patient safety and more efficient
procedures.  The  specialty  syringes are sold  separately  but are an important
component of the Company's custom kits.

          High Pressure Contrast Injection Line and Sherlock Connectors.  During
angiographic  and  diagnostic  radiology  procedures,  contrast  media  must  be
injected   through  a  catheter  into  the  blood  vessel.   This  is  sometimes
accomplished  by a mechanical  injector which can generate  pressures up to 1200
psi, and requires tubing that can withstand these pressures.  The Company offers
high  pressure  specialty  tubing  with  proprietary  Sherlock  connectors.  The
specialty  tubing is clear so that the fluid path can be observed and debubbled.
Sherlock  connectors  allow  coupling and  uncoupling of tubing with  injectors,
syringes  and  manifolds  without  overtightening  or  breakage.  The Company is
currently  offering specialty tubing which can handle pressures ranging from 500
to 1200 psi.  The  specialty  tubing with  Sherlock  connectors  is an important
component of custom kits.

          Manifolds.  The administration of saline,  imaging and contrast fluids
and the  management  of blood  pressure  monitoring,  fluid  injection and waste
collection in angiography or angioplasty  procedures is  accomplished  through a
series of valves on a manifold  which  controls  the flow of  various  fluids in
different  directions.  The Company has designed its own manifold  consisting of
two,  three,  four or five valves.  The Company  believes  its  manifold  offers
greater ease of use,  simplified  identification of flow direction and leak-free
operation  under the pressures of manual or mechanical  injection of fluids when
compared to manifolds sold by competitors. The Merit Manifold is sold separately
but is also a key component of the Company's custom kits.

          Waste  Containment  System.  Because of  heightened  awareness  of the
dangers associated with contacting blood and related waste materials,  hospitals
have moved toward closed systems whenever  possible.  To address these concerns,
the Company has designed a waste  containment  bag which  connects to a manifold
and collects waste materials such as blood and other fluids during  angiography,
angioplasty or other procedures.  The Merit Disposal Depot is self-contained for
ease of disposal and reduces risk of contamination.


                                        3





          Disposable  Blood  Pressure  Transducer.  The  Meritrans is a disposal
blood  pressure  transducer  designed  to provide  reliable  and  precise  blood
pressure  measurements.  The  device  has  a  clear  transducer  housing  and  a
flow-through design for easy flushing and debubbling.

          Safety  Basin.  The  BackStop is a fluid  disposal  basin  designed to
reduce human exposure to contaminated blood and fluids.

          Hemostasis Valves. The Passage and Access-9 hemostasis valves are used
in  conjunction  with the Company's new inflation  devices and as a component of
the  Company's  Angioplasty  Pack.  These  valves  are made  with  polycarbonate
plastics for clarity and include Sherlock  connectors.  The Passage and Access-9
valves differ primarily in size.

          Torque  Device.  The  Scout is a torque  device  which is a  guidewire
steering  device  with a tapered  design and  contrasting  colors  for  improved
visibility.  The Scout is  typically  included as a component  of the  Company's
Angioplasty Pack.

          Stopcock. The Company's Marquis Series Stopcock offers improvements on
competitive stopcock devices,  including a larger, easy grip handle. The Marquis
Series  Stopcock  is used in  connection  with  Sherlock  connectors  to provide
improved connections during procedures.

          Contrast  Management  Systems.  The  Miser  and the  In-line  Contrast
Management   System  have  been   designed  to  increase   catheterization   lab
efficiencies by reducing or eliminating contrast media waste.

          Angiographic  Needles. The angiography needle creates the percutaneous
access site for all  angiography and  angioplasty  procedures.  This site is the
point-of-entry  for  the  introducer  sheath,  guidewires,   catheters  and  any
interventional  devices.  The Merit Majestik Needle helps the physician  achieve
precision vascular access.

          Captiva(TM) Blood Containment Device. The Captiva helps protect health
care  workers from the  potential of  blood-borne  pathogens by  minimizing  the
escape of blood during an initial needle puncture in vascular access procedures.
This new  product  is  complementary  to the  recently  introduced  angiographic
needles and can be utilized in virtually  every  diagnostic  and  interventional
case where needle introducers are used.

          Fountain(TM)   Infusion  Catheter.   The  Fountain  catheter  delivers
specialized  clot-dissolving  drugs to help  remove  blood  clots  (thrombi)  in
peripheral  vessels.  This  catheter will be used to treat  peripheral  arterial
occlusions,  hemodialysis graft occlusions, and deep vein thrombosis.  Marketing
clearance was recently  obtained for U.S. and European  markets and sales of the
Fountain catheter are expected to begin in the second quarter of 1998.

          Tomcat  (TM)  (PTCA)   Guidewire.   Tomcat   guidewires  are  used  in
percutaneous  transluminal  coronary  angioplasty  (PTCA)  and stent  deployment
procedures. Guidewires are used to guide and place balloon angioplasty and stent
deployment  catheters in coronary  arteries.  This new product  complements  our
existing lines of inflation  devices and  accessories  currently used in balloon
angioplasty  procedures.  This  product  was  designed,  developed  and  will be
manufactured in the Company's Ireland facility. Marketing clearance was recently
obtained  for U.S. and European  markets and sales of the Tomcat  guidewire  are
expected to begin in the second quarter of 1998.


MARKETING AND SALES

          Market Strategy.  The Company's marketing strategy is strongly focused
on identifying and introducing highly differentiated products that meet customer
needs. The Company has targeted  selected hospital market segments in Cardiology
and  Radiology  where its  products are used.  Suggestions  for new products and
product   improvements  may  come  from  engineers,   sales  persons  and  other
radiologists and other technicians who perform the clinical procedures.

          When  a  product  suggestion   demonstrates   sustainable  competitive
advantage, meets customer needs, fits strategically and technologically, and has
good potential financial return, a "project team" is chartered with  individuals

                                        4





from Marketing,  Engineering,  Manufacturing  and Quality  Assurance.  This team
quickly and efficiently clarify the customer requirements, integrate the design,
compile  all  necessary  documentation  and  testing and prepare the product for
market  introduction.  The Company  strongly  believes that one of its marketing
strengths is its capacity to rapidly conceive,  design,  develop,  and introduce
new products.

          U.S. Sales. The Company's  direct sales force currently  consists of a
vice  president  of sales,  four  regional  sales  managers  and 36 direct sales
representatives  located in major  metropolitan  areas  throughout  the U.S. The
Company's  sales  persons  are  trained by Company  personnel  at the  Company's
facilities, by a senior sales person in their respective territories, at regular
national and regional sales meetings by consulting  cardiologists  and employees
of the Company and by observation of procedures in catheterization laboratories.

          International  Sales.  Outside of the U.S., the Company's products are
presently  sold by 42  independent  dealer  organizations  and 13  direct  sales
representatives in Germany,  France, the United Kingdom,  Canada,  Belgium,  the
Netherlands, and Ireland. In 1997, the Company's international sales grew by 15%
and accounted for  approximately 23% of total sales. The Company has appointed a
vice president for  international  sales and established an international  sales
office in Paris,  France.  With the recent and planned  additions to its product
lines, the Company believes that international sales will continue to increase.

          International  dealers are  required to  inventory  products  and sell
directly to customers  within defined sales  territories.  Each of the Company's
products  must be approved  for sale under the laws of the country in which they
are  sold.  International  dealers  are  responsible  for  compliance  with  all
applicable laws and regulations in their respective countries.

CUSTOMERS

          The Company's  principal customers in the U.S. are hospitals where the
Company's primary contacts are with the  catheterization  laboratory  directors,
cardiologists,   radiologists  and  technicians.  Hospitals  also  purchase  the
Company's products in the U.S. through custom packagers and packers who assemble
and combine products in custom kits and packs. The Company's  customers  outside
the U.S. are  hospitals  and other end users in those  countries  where a direct
sales force has been established and, in other countries are independent dealers
in medical products who resell to hospitals and other customers.

          Sales to the Company's  single  largest  customer,  a foreign  dealer,
accounted  for 5.1% of total sales during the year ended  December 31, 1997.  In
1997,  approximately  60% of the  Company  sales were made  directly to domestic
hospitals, 17% to custom packagers and packers and 23% to international markets.

RESEARCH AND DEVELOPMENT

          The  Company  believes  that  one of its  important  strengths  is its
ability to quickly adapt its expertise and  experience in injection  molding and
to apply its  electronic and sensor  technologies  to a perceived need for a new
product or product improvement.  The Company's development efforts are presently
focused on disposable,  innovative  single-patient or single-use items which can
be  included  in the  Company's  custom  kits  or sold  separately.  Longer-term
projects  include use of sensor-based  technologies in a variety of applications
and additional  inflation  devices with added capacities and features.  With the
addition  of  the  technologies  acquired  from  UMI  there  is a new  focus  on
interventional  vascular  access  products,  such as needles,  guide wires,  and
catheters  .  Certain  of  the  Company's   executive  officers  also  devote  a
substantial  portion of their time to research  and  development.  Research  and
development expenses were $4,446,795,  $2,533,171,  and $2,330,324 in 1997, 1996
and  1995,   respectively.   There  was  no  customer   sponsored  research  and
development. The Company anticipates that such expenses will be at approximately
4.0% to 6.0% of sales for 1998.






                                        5





MANUFACTURING

          Many  of  the  Company's  products  are  manufactured   utilizing  its
proprietary  technology and expertise in plastic  injection and insert  molding.
Tooling of molds is contracted  with third  parties but the Company  designs and
owns all of its molds.  The Company  utilizes its  experience  in injection  and
insert molding  technologies in the manufacture of most of the custom components
used in its products.

          The   electronic   monitors   and  sensors   used  in  the   Company's
IntelliSystem   and  Monarch  inflation  devices  are  assembled  from  standard
electronic  components or purchased  from  suppliers.  In July 1994, the Company
acquired a 73% interest in Sentir, Inc. ("Sentir"),  a Utah corporation with its
principal  offices in Santa Clara,  California,  which is engaged in development
and  marketing of silicon  sensors.  Sentir was founded in 1991 by the Company's
President  and  Chief  Executive  Officer,  Fred  P.  Lampropoulos,  to  develop
micromachining  technology and silicon  sensors.  Sentir is presently  providing
substantially  all of the  sensors  utilized  by the  Company  in certain of its
inflation devices.

          The  Company's  products  are  manufactured  at  several   facilities,
including in South Jordan, Utah, Galway, Ireland, Saratoga Springs, New York and
at recently leased expansion facilities in Murray, Utah. See "Item 2.
Properties."


COMPETITION

          The  principal  competitive  factors  in  the  markets  in  which  the
Company's  products  compete are quality,  performance,  service and price.  The
Company believes that its products have achieved rapid market acceptance due, in
part, to the quality of materials and workmanship, innovative design and ease of
operation,  the Company's attention to customer service and product managers who
respond  promptly to  customer  inquiries.  The  Company's  products  are priced
competitively, but not below prices for competing products.

          There are several  companies  which are in the business of  designing,
manufacturing and marketing devices similar to the Company's  products,  most of
which have substantially  greater financial,  technical and marketing  resources
than the Company.  There are several companies which compete with the Company in
the U.S. market for products and accessories used in angiography and angioplasty
procedures.  The Company believes, based on available industry data with respect
to the number of such procedures performed, that it is one of two market leaders
in the U.S.  for  control  syringes  (together  with NAIMIC USA  Corporation,  a
subsidiary  of  Pfizer),  and is the  leader in the U.S.  market  for  inflation
devices.  The Company also believes that the recent and planned additions to its
product  lines  will  enable it to compete  more  effectively  in both U.S.  and
international markets. There is no assurance,  however, that the Company will be
able to maintain its existing competitive  advantages or to compete successfully
in the future.

          A substantial majority of the Company's revenues are presently derived
from sales of products used in coronary angiography and angioplasty  procedures.
Other procedures, devices and drugs for the treatment and prevention of coronary
artery  disease have been  developed and are currently  being used such as laser
angioplasty,  vascular stents,  atherectomy  procedures and drug therapies,  the
effect of which may be to render certain of the Company's  products  obsolete or
to limit the markets for its products.

PATENTS, PATENT APPLICATIONS, LICENSES, TRADEMARKS AND COPYRIGHTS

          The Company  considers its  proprietary  technology to be important in
the  development  and  manufacture  of its  products  and seeks to  protect  its
technology through a combination of patents and confidentiality  agreements with
its employees and others.  Two U.S. patents  covering the mechanical  aspects of
the Company's  angioplasty  inflation devices which relate to the ability of the
user to engage or release the syringe  plunger  while  increasing  or decreasing
pressure  were  issued in 1991 and two U.S.  patents  covering  digital  control
aspects of the  Company's  IntelliSystem  inflation  device and for  displaying,
storing  and  retrieving  inflation  data were  obtained  in 1992 and 1993.  The
Company  has  obtained  other  patents  covering  each of its  Monarch and Basix
inflation devices and additional features of the IntelliSystem.


                                        6





          Corresponding patent applications  covering the claims included in the
Company's U.S.  patents and patent  applications  have been initiated in several
foreign  countries.  The Company  deems its  patents  and patents  pending to be
materially  important  to its  business  but does not  believe  its  business is
dependent on securing  such  patents.  The Company  negotiated a license in 1992
with respect to patents concerning  technology utilized in its IntelliSystem and
Monarch  inflation  devices in  consideration  of a 5.75% ongoing royalty not to
exceed  $450,000  annually.  Royalties paid in each of 1997,  1996 and 1995 were
$450,000.

          While the Company has obtained U.S.  patents and filed additional U.S.
and foreign patent  applications as discussed  above,  there can be no assurance
that issued  patents will provide the Company with any  significant  competitive
advantages  or will not be  challenged  by third  parties or that the patents of
others will not have an adverse  effect on the ability of the Company to conduct
its business.  The Company could incur substantial costs in seeking  enforcement
of its patents against  infringement or the  unauthorized use of its proprietary
technology by others or in defending  itself  against  similar claims of others.
Insofar as the  Company  relies on trade  secrets  and  proprietary  know-how to
maintain its competitive position, there can be no assurance that others may not
independently develop similar or superior technologies.

          The Company has  registered  or applied  for  registration  of several
trade names or trademarks.  See  "--Products." The Company also places copyright
notices  on its  instructional  and  advertising  materials  and has  registered
copyrights  relating  to  certain  software  used  in its  electronic  inflation
devices.

REGULATION

          The development, testing, packaging, labeling and marketing of medical
devices and the manufacturing procedures relating to these devices are regulated
under  the  Federal  Food,  Drug and  Cosmetic  Act and  additional  regulations
promulgated thereunder.  In general, these statutes and regulations require that
manufacturers  adhere to  certain  standards  designed  to ensure the safety and
effectiveness of medical  devices.  The Company employs a director of regulatory
affairs who is responsible for compliance  with all applicable FDA  regulations.
Although the Company  believes it is currently in material  compliance  with all
applicable FDA requirements,  the Company's business could be adversely affected
by failure to comply with all  applicable FDA and other  government  regulations
presently existing and promulgated in the future.

          The  FDA's  Good  Manufacturing   Practices   standards  regulate  the
Company's  manufacturing  processes,  require the maintenance of certain records
and provide for  unscheduled  inspections of the Company's  facilities.  Certain
requirements of state, local and foreign  governments must also be complied with
in the manufacture and marketing of the Company's products.

          New medical  devices may also be subject to either the Section  510(k)
Pre-Market   Notification   regulations  or  the  Pre-Market   Approval  ("PMA")
regulations of the FDA and similar health authorities in foreign countries.  New
products in either category require extensive documentation, careful engineering
and  manufacturing  controls to ensure  quality.  Products  needing PMA approval
require  extensive  pre-clinical  and clinical  testing and clearance by the FDA
prior  to  marketing.   Products  subject  to  the  Section  510(k)   Pre-Market
Notification  regulations require FDA clearance prior to marketing. To date, the
Company's  products  have  required  only  compliance  with the  Section  510(k)
Pre-Market  Notification  regulations.  The  Company's  products  are subject to
foreign regulatory approvals before they may be marketed abroad. The Company has
been  advised that it may place the "CE" mark on all  nonelectronic  devices and
products sold in Europe. The Company has received ISO 9001 certification for its
South Jordan facility.

EMPLOYEES

          As of March 23, 1998, the Company employed 989 persons,  including 780
in  manufacturing,  92 in sales and marketing,  63 in engineering,  research and
development and 54 in administration.

          Many of the  Company's  present  employees  are  highly  skilled.  The
Company's  failure or success will depend,  in part,  upon its ability to retain
such employees.  Management is of the opinion that an adequate supply of skilled
employees  is  available.  The Company has from time to time  experienced  rapid


                                        7





turnover among its entry level assembly workers as well as occasional  shortages
of such workers,  resulting in increased labor costs and administrative expenses
related to hiring and training of replacement and new entry-level employees. The
Company has confidentiality agreements with its key employees, including each of
its executive  officers.  None of the Company's  employees are  represented by a
union or  other  collective  bargaining  group  and  management  of the  Company
believes that its relations with its employees are good.

FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES

          For  financial  information  relating  to the  Company's  foreign  and
domestic sales,  transfers between geographic areas net income and indentifiable
assets,  see note 8 to the  Consolidated  Financial  Statements  incorporated by
reference in this report


Item 2.           Properties.
                  -----------

          The Company is the owner of  approximately  35 acres of real  property
situated in the city of South  Jordan,  Utah,  which  surrounds  the site of its
175,000  square  foot  principal  office  and  manufacturing  facility  where it
relocated and consolidated  operations in November 1994. The Company sold to the
developer  ten acres of land on which the facility was  constructed  and entered
into a 25-year  lease  agreement  to finance  the new  facility.  Monthly  lease
payments  are  approximately  $108,000.  The  Company  also  holds an  option to
purchase the facility,  exercisable  at market value after ten years and, if not
exercised,  after  25  years.  The new  facility  has  been  constructed  to the
Company's specifications and is presently 75% utilized.

          The Company is leasing a building of approximately  26,500 square feet
in Galway,  County  Galway,  Republic of Ireland as its  principal  office,  and
manufacturing  facility for European  operations.  This  facility is used as the
administrative  and  distribution  headquarters  to support the European  direct
sales force.  The facility also houses a research and development team which has
developed a new PTCA guidewire and is developing  other new products.  Beginning
in the fourth quarter of 1997, the Company  initiated  manufacturing  operations
for several new and existing  products at the Galway facility,  including custom
kits, the BASIX inflation device and the Company's PTCA guidewire.  The property
has been been  improved  and  equipped  on terms  favorable  to the  Company  in
connection with economic development grant incentives and grants provided by the
Irish Government. This lease is for 20 years at approximately $135,000 per year,
less a 40%  subsidy  from the Irish  government,  available  through  1999.  The
Company also has a purchase option  exercisable on terms deemed favorable to the
Company through the term of the lease.

          The  Company  has  acquired  approximately  1 1/2  acres of land and a
building of  approximately  25,000 square feet in Castlerea,  County  Roscommon,
Republic of Ireland, which is being held for sale.

          In February,  1997,  the Company  entered into an 18-month lease (with
options to extend for three  additional  two-year terms) of a 32,000 square foot
facility  in  Saratoga  Springs,  New York,  from UMI where  the  product  lines
acquired  from UMI  (needles,  catheters and  guidewires)  are  currently  being
manufactured.

          In October  1997,  the Company  began  manufacturing  operations  in a
facility of  approximately  25,000 square feet of  manufacturing  space formerly
occupied  by the  Company  in Murray,  Utah and  shifted  production  of several
well-established  products to this facility. The additional  manufacturing space
was obtained to create room at the company's  principal  manufacturing  facility
for  production  of new  products.  The lease is for a term of five  years  with
monthly lease payments of approximately $13,900.

          The Company  believes that its facilities  are generally  adequate for
its present level of operations  and for  anticipated  increases in the level of
operations.

Item 3.           Legal Proceedings.
                  ------------------

          On February 4, 1994, an action was filed in the Third  District  Court
of Salt Lake County, State of Utah by an individual claiming to be a shareholder
of the Company and naming the Company,  Fred P.  Lampropoulos,  President of the
Company, and Sentir, a company founded by Mr. Lampropoulos,  as defendants.  The
claims  against the Company were  subsequently  dismissed.  The  complaint  also
asserts  claims  on  behalf  of the  Company  (derivative  claims)  against  Mr.
Lampropoulos  and Sentir,  alleging  breach of fiduciary  duty, and the improper
taking of a corporate  opportunity  in connection  with the formation of Sentir.
The  relief  sought  in  connection   with  the   derivative   claims   included
disgorgement,  costs, and attorney's fees. The Company  appointed an independent
Special  Litigation  Committee of the Board to determine the Company's course of
action  on the  derivative  claims  which  engaged  counsel  separate  from  the
Company's  usual counsel for purposes of the derivative  claims.  On November 7,
1995,  pursuant to a Motion filed on behalf of the Company's Special  Litigation
Committee,  the Court made a minute  entry  granting  the motion to Dismiss  the
derivative  claims,  without  prejudice.   On  November  4,  1996,  the  Special
Litigation  Committee  delivered  its  report  essentially  concluding  that the
derivative claims were not well founded.  Nevertheless, on November 22,1996, the
plaintiff refiled only the derivative claims in the Third District court of Salt
Lake  County,  State of Utah and on January  22,  1997,  a motion to dismiss was
filed on  behalf  of the  Company,  seeking  to  terminate  the  litigation  and
asserting  that the report of the Special  Litigation  Committee  is entitled to
deference under the law.
