                                     Part I

Item 1.   Description of Business.

     Luther Medical Products, Inc., a California corporation (the "Company"),
since its organization in 1980 has been primarily engaged in the design,
development, manufacture, sale, and licensing of intra-vascular catheters and
split, peel-away needles.  The Company's L-Cath/(TM)/ peel-away needle catheter
placement system and the OneCath/(R)/ protected needle catheter placement
systems are used when soft, flexible catheters must be inserted for short- and
long-term intravenous therapy.  The L-Cath for Ports is used to insert a soft,
flexible catheter into an implanted port as an alternative to a steel Huber
needle.

Products
--------

Peripherally Inserted Central Catheters ("PICCs").

     PICCs provide venous access and typically reach into the superior vena cava
to serve as a "central line."  The Company's patented peel-away needle has been
central to the Company's PICC products.  A PICC is indicated for the following
clinical reasons:  (i) lack of peripheral venous access, (ii) infusion of
vesicant/irritant drugs, (iii) long-term intravenous therapy in the home,
hospital, or clinic setting, (iv) administration of blood/blood products, or (v)
infusion of intermittent drug therapy.

     The Company believes that PICCs provide certain non-economic advantages
over conventional intravenous catheters, e.g., reliable vascular access
throughout the course of therapy and decrease in patient pain and discomfort
associated with frequent venipuncture.  In addition, the Company believes that
certain economic advantages also exist.  For example, PICCs may be left in place
for two to six weeks or more as compared to traditional over-the-needle
catheters that must be changed every 48 hours.  One PICC may substitute for up
to 20 short-term catheters, saving up to 19 procedures.  The Company estimates
that the current domestic market for PICCs is approximately $38 million and
that the Company is the second or third largest domestic supplier of PICCs.

Peripherally Inserted Midline Catheters ("Midlines")

     Midlines provide venous access with the tip of the catheter located in the
upper arm.  A Midline is indicated for the following clinical reasons:  (i)
certain types of peripheral IV solutions, (ii) two to six week short-term IV
therapy, or (iii) providing venous access when a PICC is contraindicated.
Midlines provide similar economic advantages as PICCs.  The Company estimates
that the current domestic market for Midlines is approximately $9 million and
that the Company is the largest domestic supplier of Midlines.

Peripherally Inserted Long-Term Peripheral Catheters ("Long-Term Peripherals")

     Long-Term Peripherals are similar to Midlines, except that they are more
likely to be used for shorter time frames.  Long-Term Peripherals are an
alternative to traditional, short, hard IV catheters that must be replaced every
48 to 72 hours.  Long-Term Peripherals, which

                                      -2-
<PAGE>
 
can remain in place for more than 30 days, if required, bridge the time gap
between such traditional IV catheters and  Midlines.

L-Cath/(TM)/ PICC, Midline, and Long-Term Peripheral Catheter Placement Systems.

     The Company's patented peel-away needle catheter placement system consists
of a stainless steel needle (the "cannula") through and by which a flexible
catheter is inserted.  The cannula is sharpened to a fine point on one end and
has an extremely narrow slit along its entire length.  Once a cannula has been
inserted into a blood vessel, the catheter is inserted into the cannula and
advanced into the vessel.  After the catheter has been advanced to the desired
level of insertion, the needle is withdrawn.  Rather than attempting to thread
the needle back over the length of the catheter outside the body and off the end
(an end that may have a large connecting adapter rendering removal impossible),
the needle is peeled or split lengthwise in two and is removed from the
catheter.

     The L-Cath/(TM)/ catheter placement systems may be used in a variety of
biomedical applications.  In the medical market, for example, catheters are
advanced into a vein, thereby allowing the clinician to administer plasma,
blood, chemotherapy, intravenous drugs, or feeding solutions.

     The L-Cath/(TM)/ catheter placement system are currently manufactured and
sold in a variety of sizes and configurations for applications ranging from
neonatal (infants) to adult to veterinary. The L-Cath catheter system is
available in either polyurethane or silicone materials.

OneCath/(R)/ Catheter.

     The OneCath/(TM)/ catheter placement system has been designed as a new
generation of PICCs or Midlines. The OneCath catheter placement system
incorporates the advantages of many of the Company's earlier developments and
certain protection against accidental needle sticks. The OneCath allows for the
insertion of central venous catheters or Midlines made from soft biocompatible
material using conventional "over-the-needle" techniques with a protected needle
that is designed to give protection from needle stick injuries that could result
in AIDS and other infectious diseases.

L-Cath Catheter for Port Access.

     The L-Cath/(TM)/ for Ports is a soft catheter utilized in the infusion of
fluids into the blood stream through a small implanted chamber (a port) inserted
under the skin of a patient's chest. In August of 1994, the FDA granted the
Company clearance to market the L-Cath/(TM)/ for Ports, a market currently
served only by steel needle manufacturers. Management believes that the L-Cath
for Ports offers certain advantages in comparison with traditional steel
needles, including increased comfort for the patient and reduced inventory
levels for the healthcare provider. The L-Cath/(TM)/ for Ports catheter will
bend in response to external forces applied to it, or to its connections, e.g.,
                                                                         ------
a patient rolling over in bed; whereas, a steel needle would not bend, but would
cause the patient noticeable pain. Because the distance under the skin at which
ports have been implanted will vary depending on the patient and the surgeon's
preference, healthcare providers typically maintain many lengths of steel
needles in

                                      -3-
<PAGE>
 
inventory.  The L-Cath for Ports can satisfy virtually any length requirement
simply by bending  the soft catheter outside of the skin.

Stickless Technology.

     Currently, the Company's OneCath catheter placement system incorporates
stickless technology.  See Item 1. Description of Business -- Research and
Development.  When placing a catheter into a patient, the health care worker is
at significant risk of receiving an accidental needle stick.  The needle may be
contaminated by any one of a variety of potentially infectious diseases.  The
degree to which the health care worker is at risk of becoming infected is
directly dependent upon the degree to which the disease is transmittable.

     AIDS and other infectious diseases have been shown to be transmittable from
patient to health care worker via contaminated needles.  Management believes
that (a) health care workers and hospital administrators are highly motivated to
reduce the possibility of transmission of such diseases and (b) the insurance
industry is also highly motivated to reduce the risks (and associated costs) of
such infectious diseases.  Furthermore, management believes that nurses' unions
and government agencies, e.g., Occupational Safety and Health Administration,
                         -----
may require that needle guards be used when treating potentially infectious
patients.  The present directive of the Centers for Disease Control and
Prevention in Atlanta, Georgia, is that hospital workers treat all patients as
potentially infectious; hence, care-givers must take certain necessary
precautions.  Those precautions do not currently include the mandated use of
needle guards and there can be no assurance that any union or government agency
will require the use of needle guards.  However, the design of the OneCath
catheter placement system incorporates technology that provides increased
protection against accidental needle sticks to health care workers.

Pertrach Technology.

     The Pertrach tracheostomy device (the "Pertrach Tracheostomy Product")
provides a means of rapidly and safely inserting a breathing tube into a
patent's trachea (through their crico-thyroid membrane or trachea) in certain
clinical situations.  It provides an adequate airway through which the patient
can receive airflow.  The method of inserting the device is by dilating a needle
puncture.  Because of the small size of the puncture, a patient typically
suffers minimal bleeding and the chance of infection is reduced.  Deploying the
Pertrach Tracheostomy Product has been demonstrated to take 30 seconds or less
to perform.

Implantable Vascular Acess Medical Devices

     Effective September 23, 1998, the Company entered into a Distributorship 
Agreement and a Technology License Agreement with Biocontrol Technology, Inc. 
("BICO"), a Pennsylvania manufacturer and marketer of implantable vascular
access medical devices and related products known as theraPORT/(R)/. In the
first agreement, BICO appointed Luther as a non-exclusive distributor of such
products in the United States. The term of the first agreement is one year,
renewable in one year increments. In the second agreement, BICO granted an
irrevocable, non-exclusive right and license to the Company for it to use all
proprietary and intellectual information and property relating to the thereaPORT
implantable vascular access 

                                      -4-
<PAGE>
 
system and product lines, and all information useful in the design, development,
manufacture, marketing, use and sale of such products. The rights granted to the
Company are transferable only in the event of a business combination
transaction.

Marketing and Customers
-----------------------

     The Company's current marketing strategy is to distribute its catheter
products primarily through a specialty distribution network.  The Company may
develop and manufacture products, some of which may incorporate the Company's
patented technology for distribution on an OEM basis.  The Company may also
license portions of its technology.

     In March of 1992, the Company entered into an exclusive distribution
agreement with Pharmacia Deltec Inc., now known as Sims Deltec Inc.  ("Sims")
for the Company's PICC and Midline products.  In 1994 the Company and Sims
agreed to terminate the exclusive nature of the agreement.  In March 1994, Sims
became a non-exclusive distributor for a broad range of the Company's products
and the Company commenced the establishment of a distribution network through
specialty distributors.  Effective March of 1995, and for the four-year period
thereafter, Sims was permitted only to distribute the Company's neonatal
products.

     Management believes that the current size of the markets for PICCs and
Midlines in the United States is approximately $40 million annually and that it
is expanding at an annual rate of 15%.  The Company believes that the market
will continue its growth due to the continued efforts of the medical insurance
industry to reduce health care costs and the collateral movement of health care
delivery from the hospital to the outpatient setting.  The Company believes that
its products are lower cost alternatives to established therapy.

     Management believes that the current size of the market for implanted port
catheters in the United States will be approximately ten percent of the $150
million annual market that is currently served only by Huber steel needle
manufacturers.  The Company believes that its distribution network is properly
positioned to address the implanted port catheter market and to gain market
share for the Company.  Many of the Company's distributors also sell Huber
needles.

Distribution Network.

     In March of 1994, the Company commenced the establishment of a network of
specialty distributors to encompass the United States and Canadian markets.  In
addition, the Com-

                                      -5-
<PAGE>
 
pany has appointed a number of international distributors. As of the date of
this Annual Report, the Company has full coverage of the United States and
Canadian marketplace through approximately 17 distributors, resulting in more
than 150 sales personnel engaged in sales efforts for the Company's products.

     In August of 1994, the Company entered into a five-year distribution
agreement for the states of California, Arizona, Nevada, and New Mexico with
Kentec Medical, Inc. ("Kentec"). The Company granted Kentec certain pricing
accommodations during a transition period. The agreement provides certain
termination criteria for the Company and for Kentec. The Company may terminate
the agreement if Kentec fails to purchase sufficient quantities of the Company's
products. Kentec may terminate the agreement if, during the term of the
agreement and under certain circumstances, the Company (i) commences direct
sales into Kentec's territory without its written consent or (ii) is a party to
a business combination transaction, the resulting enterprise of which chooses
not to assume the agreement. Kentec shall be entitled to a fee if it terminates
the agreement upon the occurrence of either such event. For each year or part
thereof remaining of the then-unexpired term of the agreement, such fee (to be
paid annually) shall be a sum equivalent to 30% of the aggregate transfer price
for products sold by the Company to Kentec during the immediately preceding 12
months. In the case of such a termination, Kentec is to receive the initial
annual payment of such fee within 30 days.

     In August of 1997, the Company entered into a five-year distribution
agreement with Alaris Medical Systems, Inc. ("Alaris"), for the EEC and certain
other foreign countries.  The agreement contains certain termination provisions
that may come into effect in the event that the Company and Alaris are unable to
reach agreement regarding Alaris's performance goals for the second through
fifth years of the agreement.  In addition, the agreement may be terminated, and
payment of a termination fee will be required, in the event that the Company is
a party to a business combination transaction, the resulting enterprise of which
chooses to terminate the agreement.  If the agreement is terminated either
because of the parties' inability to agree on performance goals or because of
the actions of the Company's successor, Alaris shall retain rights to continue
to distribute such products for a period of up to two years.

Licensed Technology.

     In October of 1993, the Company signed a "life of the patents" agreement
with The Kendall Company ("Kendall") for North and South America, pursuant to
which the Company licensed Kendall to use certain of the Company's patent rights
and technology relating to the Company's peel-away needles in research and
development, manufacturing, marketing, and selling peel-away needles used in
connection with epidural and/or spinal anesthesia. Under certain circumstances,
Kendall may lose exclusivity to the rights granted in the agreement. As of the
date of this Annual Report, Kendall has not obtained 510(k) clearance to market
such products.

     In March of 1992, the Company entered into an exclusive distribution
agreement with Sims for the Company's PICC and Midline products.  Effective
March of 1995, and for the four-year period thereafter, Sims was permitted only
to distribute the Company's neonatal products.

                                      -6-
<PAGE>

Interventional Radiology.

     In September of 1995, the Company entered into a product development and
supply agreement with Boston Scientific Corporation ("BSC"), pursuant to which
the Company undertook to manufacture (to BSC's specifications) and BSC
undertook to sell (on an exclusive basis) a jointly developed range of PICCs to
be used exclusively in the interventional radiology market for patients who
require percutaneous access to the vascular system.

Order Backlog
-------------

     The amount of backlog orders believed by the Company to be firm, as of June
30, 1998, for catheter production was $575,000.  The Company expects that all of
such backlog will be filled within the current fiscal year. As of June 30, 1997,
such backlog orders were approximately $558,000 for catheter production.

Production and Supplies
-----------------------

     Many of the components of the catheter product lines can have more than one
source of supply, although the Company has not traditionally multi-sourced its
components.  The Company believes that it would be able to switch its sources of
supply without causing significant disruption to its manufacturing or marketing
operations.  The Company owns the designs and molds for the components that are
proprietary to the Company and can relocate the molds at its discretion to
numerous alternative molders in its local area.

Government Regulation
---------------------

     The FDA classified the Company's catheter placement systems as Class II
medical devices under the Federal Food, Drug and Cosmetic Act (the "FFD&C
Act").  This classification requires the Company to obtain clearance from the
FDA prior to marketing its catheter products.  The Company has had and will
continue to have its products clinically tested in hospitals and other
institutions to ensure the fitness for, and ease of, use of the catheter
placement systems. Under the FFD&C Act and applicable FDA regulations, the FDA
may periodically inspect the manufacturing facilities of the Company, and the
Company must comply with certain methods, facilities, controls, labeling,
recordkeeping, and reporting requirements in manufacturing and marketing its
catheter placement systems. During the 1997 fiscal year, the Company expended
$317 thousand to modify its internal quality assurance and regulatory affairs
system. Of such sum, $49 thousand was included in the Company's cost of
revenues, $262 was included in the Company's general and administrative
expenditures, and six thousand dollars was included in the Company's research
and development expenditures. See Item 6. Management's Discussion and Analysis
or Plan of Operation -- Results of Operations.

     The manufacture and sale of medical devices are also regulated by some
states, including California, and most foreign countries.  The Company has
obtained its manufacturing license from California and is not aware of any other
state approvals necessary at this time. The Company will require each foreign
distributor to obtain all necessary regulatory approvals to market the Company's
catheter placement system in the countries in which the distributor 

                                      -7-
<PAGE>

intends to market the product. Management believes that the Company's
distributors have obtained all necessary international approvals for products
currently being sold.

Patents
-------

Patents.

     During the fiscal years ended June 30, 1998, 1997, five patent applications
were filed, of which one has been issued, two are in the issuance process, and
two are pending as of the date of this Annual Report.  In addition, in respect
of patent applications filed during prior years that had not been granted as of
June 30, 1996, seven were issued during such two-year period, two were in the
issuance process, and three remained pending.
 
     The Company is the assignee of three patents related to the Pertrach
Tracheostomy Product.  See "Item 1.  Description of Business -- Products --
Pertrach Technology."

General Patent Protection.

     To date, no court has ruled on the enforceability of any of the Company's
patents.  There is no assurance that the Company's patents or any future patents
will afford protection broad enough to prevent competitors from manufacturing
systems similar to the Company's.  In defense of its intellectual property
rights, the Company was successful in compelling Gesco International, Inc.
("Gesco") to cease its infringement of one of the Company's split-needle
patents.  Subsequently, Gesco was acquired by Bard Access Systems.  The Company
has purchased a policy of patent insurance to supplement its financial
resources in the prosecution of infringement of its major patents.

Competition
-----------

     Many larger medical companies, e.g., Abbott Laboratories, Bard Access
                                    -----
Systems, Baxter Healthcare Corp., B. Braun Medical Inc., Becton-Dickinson
Vascular Access, Johnson & Johnson Medical, Inc. Vascular Access, and Sims,
dominate the general catheter and port access segments of the medical device
industry and compete with the Company on the basis of product performance.
Management believes that such larger companies neither offer a range of products
that better suits the needs of the patients nor utilize better channels of
distribution to service the PICC and Midline markets. Although the Company does
not have the financial or distribution resources to supplant the market position
of such larger companies with respect to the specific catheter products
manufactured and marketed by them, management believes that the Company can be
successful in manufacturing and supplying PICCs and Midlines to the markets that
can utilize such products. Accordingly, the Company has adopted a strategy of
marketing its products primarily through its network of specialty distributors,
as well as through selective licensing arrangements.

Research and Development
------------------------

     Since the 1987 introduction of stickless technology with PROTECTIV (a
catheter product licensed by the Company to Critikon, Inc., a Johnson & Johnson
company ("Critikon"), the 

                                      -8-
<PAGE>

Company has concentrated on the development of additional products for its
distribution network, which products include other stickless product designs, as
well as the OneCath catheter, L-Cath for Ports, high flow-rate catheters, dual
lumen products, and closed-end, slit-valve intravenous catheters.

     Current areas on which the Company is concentrating its efforts include
needle stick protection for healthcare workers, reduced exposure to blood,
increased dwell time (the time that a catheter may remain in a vein before it
must be removed), ease of use with a related reduction in training time, and
improved patient comfort.  There can be no assurance that any commercially
feasible products will result from such research and development activities.
During the fiscal years ended June 30, 1998, and 1997, the Company expended an
aggregate of approximately $368,000 and $521,000, respectively, on catheter
research and development efforts.
 
Employees
---------

     The Company employs 55 individuals.  The Company's employees are not
covered by any collective bargaining agreement, and management believes its
relationship with its employees is good.

Item 2.   Description of Property.

     The Company's executive office and manufacturing facility is located in
leased premises at 14332 Chambers Road, Tustin, California.  The property
comprises approximately 20,000 square feet of light industrial space.  The
leasehold improvements include approximately 4,350 square feet of a controlled
manufacturing environment suitable for medical device manufacturing, as well as
air, vacuum, and electrical systems.  The Company believes that its facilities,
as improved, are suitable and adequate for its business, as currently conducted
and for the foreseeable future.  The Company believes that the facilities
provide it with productive capacity sufficient to enable it to meet its current
production goals and requirements, and those for the foreseeable future.
Management believes that the facilities, as currently situated, could support a
tripled level of production of current catheter products.  The Company leases
such facility on a month-to-month basis, subject to termination with not less
than six months' written notice by either party.

Item 3.   Legal Proceedings.

     The Company is not a party to any legal proceedings and management is not
aware of any threatened legal proceedings.

Item 4.   Submission of Matters to a Vote of Security Holders.

     There were no matters submitted during the fourth quarter of the year ended
June 30, 1998, to a vote of security holders through the solicitation of proxies
or otherwise.

</TABLE>

     The closing price of the Company's Common Stock as of September 21, 1998,
was $2.88.  At September 21, 1998, the Company had approximately 3,000 record
holders of its Common Stock.

     The Company did not declare or pay any dividends during either of its
fiscal years ended June 30, 1998, and 1997.  Payment of dividends, if any, on
the Common Stock, is dependent upon the amounts of future after-tax earnings, if
any, of the Company and is subject to the discretion of its Board of Directors.
The Board of Directors is not legally obligated to declare dividends, even if
the Company is profitable.  To date, the Company has not declared or paid any
dividends.  The Company intends to employ all available funds to finance the
growth of its business and, accordingly, does not intend to declare or pay any
dividends in the foreseeable future.

     The Company commenced business operations in 1980 (as the successor to a
partnership organized in 1979) to develop, manufacture, and market a
proprietary catheter placement system and related products.  The Company has
financed its development activities and operations since inception through
product sales, licensing revenues, and net proceeds from sales of securities
(both public and private issuances), funds received under a research and
development agreement funded by a limited partnership to develop certain small
catheter systems, and the proceeds of a sale by the Company of five of its
patents to Johnson & Johnson Medical, Inc. ("JJMI").

                                      -10-

     Development continues on new models of catheter systems for various
applications.  Since its inception, the Company has developed and introduced
numerous versions of its catheter placement products and systems, and additional
catheter products are in development.  There can be no assurance that any
additional commercially feasible products will result from such current
development activities.

     Historically, the Company focused on research and development, rather than
marketing.  In November of 1987, a significant private label agreement was
entered with Critikon, under which the Company manufactured its PROTECTIV
catheter product for distribution by Critikon; in March of 1990, Critikon
commenced to manufacture the product and paid the Company a sales-based royalty;
and in March of 1995, the Company assigned to JJMI the PROTECTIV patents for
$4.4 million, net of expenses.  In 1990, the Company commenced the marketing of
a PICC product line utilizing its L-Cath catheter placement system.  In March of
1992, the Company entered into an exclusive distribution agreement with Sims for
the Company's PICC and Midline products that use a peel-away needle, including
catheters for adults and certain neonate catheters, which agreements became non-
exclusive in March of 1994.  Effective March of 1995, Sims was permitted only to
distribute the Company's neonatal products for an additional four years.  See
Item 1. Description of Business.

     In March of 1994, the Company commenced the establishment of a network of
specialty distributors to encompass the United States and Canadian markets.  In
addition, the Company has appointed a number of international distributors.  As
of the date of this Annual Report, the Company has approximately 17
distributors, resulting in more than 150 sales personnel engaged in sales
efforts for the Company's products.  As of the date of this Annual Report,
substantially all of the distributors have received training in the use of the
products.

Fiscal Year Ended June 30, 1998, Compared To Fiscal Year Ended June 30, 1997.

     Total revenues for 1998 increased five percent to $5.7 million from $5.5
million in 1997.  Domestic sales revenues for 1998 increased 15% to $5.04
million from $4.39 million in 1997, primarily as a result of increased OEM sales
and the contribution from the "extended dwell peripheral" product line.
International sales revenues for 1998 decreased 37% to $640 thousand from $1.0
million, primarily as a result of reduced sales to the Company's Japanese
distributor.  In August of 1998, the Japanese Ministry of Health approved the
modified and improved version of the Company's neonate products for sale in
Japan and the Company recommenced shipment of its products to Japan.  Interest
and royalty income decreased 38% to $47 thousand from $76 thousand in 1997,
primarily as a result of a decrease in interest earned on available cash which
was invested in U.S. treasury bills.  There were no production costs associated
with any royalty income.

     Cost of revenues for 1998 increased to $3.5 million from $3.3 million in
1997.  Cost of revenues as a percentage of product sales remained at 61%.

     Selling expenses for 1998 decreased 6% to $1.1 million from $1.1 million in
1997.  General and administrative expenses for 1998 increased slightly to $1.1
million from $1.0 million in 1997.  Research and development expenses for 1998
decreased 29% to $368 thousand from $521 thousand in 1997, as a result of
reduced compensation and project expenses.

                                      -11-
<PAGE>
 
Depreciation and amortization expenses decreased in 1998 to $201 thousand from
$234 thousand in 1997.  The Company recorded a provision for minimum income
taxes of $800 for 1998 and 1997.  At June 30, 1998, the Company had net
operating loss carryforwards of approximately $4.8 million and $719 thousand
available to offset future taxable federal and state income, respectively.  The
carryforwards amounts expire in varying amounts between 2001 and 2013.

Liquidity and Capital Resources
-------------------------------

     At June 30, 1998, the Company had working capital of $2.7 million and its
principal sources of liquidity consisted of $411 thousand in cash and cash
equivalents.  The Company used cash for operations of $389 thousand during 1998,
mainly as the result of the net loss for the year and an increase in inventories
resulting from higher sales levels.  With respect to investing activities, the
Company made purchases of property and equipment totaling $88 thousand.
Financing activities provided $76 thousand, resulting from the collection of a
note receivable from a shareholder and the sale of common stock through the
exercise of options.

     The Company has no long-term capital commitments other than an annualized
lease obligation of $164,000, which lease is subject to termination with not
less than six months' written notice by the Company or its lessor.

     The Company believes that available cash and cash equivalents, as well as
funds expected to be generated from operations, will be sufficient to meet the
Company's operating expenses and cash requirements for the next fiscal year.  As
of the date of this Annual Report, the Company does not have any credit
facilities in place.

Impact of Year 2000
-------------------

     Some of the Company's older accounting programs were written using two
digits rather than four digits to define the applicable year.  As a result,
those computer programs have time-sensitive software that recognize a date using
"00" as the year 1900 rather than the year 2000.  This could cause a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.  The Company has completed an
assessment of its internal computer programs and will have to modify or replace
portions of its software so that its computer systems will function properly
with respect to dates in the year 2000 and thereafter. The total Year 2000
project cost is estimated at approximately $25,000, which will be capitalized
upon acquisition of the appropriate hardware and software.

Forward-Looking Statements
--------------------------

     Certain statements made above relating to plans, conditions, objectives,
and economic performance go beyond historical information and may provide an
indication of future results.  To that extent, they are forward-looking
statements within the meaning of either or both of Section 27A of the Securities
Act of 1933 or Section 21E of the Securities Exchange Act of 1934, and each is
subject to factors that could cause actual results to differ from those in the
forward-looking statements.  These forward-looking statements include statements
based on

                                      -12-
<PAGE>
 
current expectations that involve a number of risks and uncertainties and are
based on assumptions regarding the Company's business and technology.  Such
assumptions involve judgments with respect to, among other things, future
scientific, economic, and competitive conditions, and future business decisions,
all of which are difficult or impossible to predict accurately and many of which
are beyond the control of the Company, e.g., (i) future research and
                                       ----
development, manufacturing, and marketing plans, expenditures, and potential
results, (ii) potential collaborative arrangements, (iii) the potential utility
of the Company's products and proposed products, and (iv) the potential need
for, and availability of, additional financing.  Although the Company believes
that the assumptions underlying the forward-looking statements are reasonable,
such risks and uncertainties may materialize and actual results may vary
materially from those anticipated, estimated or projected.

     In light of the significant uncertainties inherent in the forward-looking
information included herein, the inclusion of such information should not be
regarded as representations by the Company or any other person that the
objectives or plans of the Company can, or will, be achieved.  In any event,
these forward-looking statements speak only as of their dates, and the Company
undertakes no obligation to update or revise any of them, whether as a result of
new information, future events, or otherwise.  The Company intends that such
forward-looking statements be subject to the safe harbors created by such
sections of such Acts.

Exchange Act), directly or indirectly, of securities of the Company representing
80% or more of the combined voting power of the Company's then outstanding
securities.

Item 12.  Certain Relationships and Related Transactions.

     As of June 30, 1998, the spouse of a then-current officer of the Company
was indebted to the Company in the aggregate amount of $49,979.  Such
indebtedness was incurred in connection with the exercise of options previously
granted to such individual.  Such obligation was extinguished through the
return by such individual of 16,643 shares of the Company's common stock that
had served as security for such obligation.  In addition, during the 1998 fiscal
year, the maximum aggregate obligation to the Company of such then-current
officer and a then-current director of the Company was $235,409, which was
repaid to the Company during such year.

     During the Company's fiscal year ended June 30, 1998, the Company sold 
approximately $565,000 of its products to Columbia in the ordinary course of 
their respective businesses. Such sales represented less than ten percent of the
Company's overall sales and 11.2% of its domestic sales and, management of the 
Company believes, less than four percent of Columbia's purchases of products 
from all of its sources. Mr. Huck, one of the Company's directors, serves as 
Chairman of the Board and Chief Executive Officer of Columbia, which, 

                                      -20-

effective September 1, 1998, disposed of its specialty medical device
distribution (Midwest) division, which division had purchased and resold the
Company's products.

provided certain legal services to the Company.  Such services totaled less than
$60,000.  Mr. Katz, the assistant secretary of the Company, is a partner in
Arter & Hadden LLP.

                         Report of Independent Auditors

To the Board of Directors of
Luther Medical Products, Inc.

We have audited the accompanying balance sheet of Luther Medical Products, Inc.
as of June 30, 1998, and the related statements of operations, stockholders'
equity and cash flows for each of the two years ended June 30, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Luther Medical Products, Inc.
as of June 30, 1998 and the results of its operations and its cash flows for the
two years then ended in conformity with generally accepted accounting
principles.

                         Notes to Financial Statements

                                 June 30, 1998



1. Summary of Significant Accounting Policies

Description of Business

Luther Medical Products, Inc. (the Company) was organized in 1980 to design,
development, manufacture and sale of catheter placement systems. The Company
holds numerous patents for a wide variety of catheter placement systems. The
Company sells its products world-wide primarily through independent
distributors. Approximately 89% and 81% of product sales during 1998 and 1997,
respectively, were domestic. The Company considers its business to be in the
medical devices industry.

Use of Estimates

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

Revenue Recognition

Revenues on product sales are recognized at the time of shipment. Royalty fees
are recognized as earned.

Certain Concentrations

The Company provides credit in the normal course of business to customers
throughout the United States and foreign markets. During 1998, two customers
accounted for approximately 9% and 8%, respectively, of total product sales, and
during 1997 two customers accounted for approximately 12% and 9%, respectively,
of total product sales. At June 30, 1998, two customers accounted for
approximately 18% and 9%, respectively, of accounts receivable. The Company
performs ongoing credit evaluations of its customers. The Company does not
obtain collateral with which to secure its accounts receivable. The Company
provides for potential credit losses based upon the Company's historical
experience related to credit losses.

                                                                               6

1. Summary of Significant Accounting Policies (continued)

Certain Concentrations (continued)

During 1998, two of the Company's vendors accounted for approximately 37% and
12%, respectively, of material and supply purchases, and during 1997, two
vendors accounted for approximately 26% and 9% of the Company's material and
supply purchases. At June 30, 1998, two vendors accounted for approximately 32%
and 7%, respectively, of accounts payable. The Company believes that it could
purchase such materials and supplies from other vendors without a material
adverse effect to the Company.

Fair Value of Financial Instruments

The Company has financial instruments whereby the fair value of the financial
instruments could be different than that recorded on a historical basis on the
accompanying balance sheet. The Company's financial instruments consist of cash
and cash equivalents, accounts receivable and accounts payable. The carrying
amounts of the Company's financial instruments generally approximate their fair
values at June 30, 1998.

Cash and Cash Equivalents

For consolidated financial statement purposes, cash and cash equivalents are
defined as highly liquid holdings which have remaining maturities of three
months or less when purchased. The Company holds Certificates of Deposit
totaling $300,000 which are considered to be cash equivalents at June 30, 1998.

Investments

The Company accounts for its investments in accordance with Statement of
Financial Accounting Standards No. 115, (SFAS 115), Accounting for Certain
Investments in Debt and Equity Securities, which requires that investments be
classified as "held-to-maturity", "available-for-sale" or "trading securities".
The Company has no investments which qualify for such treatment under SFAS 115
at June 30, 1998.

                                                                               7

1. Summary of Significant Accounting Policies (continued)

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is
determined under the first-in, first-out method. Costs include materials, direct
labor, and an allocable portion of direct and indirect manufacturing overhead
based upon standard rates derived from historical trends and experience factors.
The industry in which the Company operates is characterized by technological
changes. Should demand for the Company's products prove to be significantly less
than anticipated, the ultimate realizable value of such products could be less
than the amount shown in the accompanying balance sheet.

Property and Equipment

Property and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives of the respective assets of
five years. Leasehold improvements are amortized over the lesser of the
estimated useful lives of the improvements or the related lease term.

Long-Lived Assets

The Company records impairment losses on long-lived assets used in operations
when events and circumstances indicate that the assets might be impaired and the
undiscounted cash flows estimated to be generated by those assets are less than
the carrying amount of those assets. No impairment losses were recorded in 1998
or 1997.

Advertising

The Company expenses all advertising as incurred. Advertising expense was
$39,558 and $28,801 in 1998 and 1997, respectively.

Income Taxes

The Company provides for income taxes under the liability method. Accordingly,
deferred tax assets and liabilities are determined based on differences between
the financial reporting and the tax basis of assets and liabilities that will
result in taxable or deductible amounts in the future based on enacted tax laws
and rates applicable to the period in which the differences are expected to
affect taxable income. Valuation

                                                                               8

1. Summary of Significant Accounting Policies (continued)

Income Taxes (continued)

allowances are established when necessary to reduce deferred tax assets to
amounts which are more likely than not to be realized. The provision for income
taxes represents the tax payable or refundable for the period plus or minus the
change during the period in deferred tax assets and liabilities.

Per Share Amounts

In 1997, the FASB issued Statement No. 128, Earnings Per Share, which replaced
the calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike earnings per share, basic earnings per share
excludes any dilutive effects of options, warrants, and convertible securities.
Diluted earnings per share is similar to fully diluted earnings per share.

Loss per share for June 30, 1998 and 1997 is calculated based on Statement of
Financial Accounting Standards No. 128. The following table sets forth the
computation of loss per share for the years ended June 30, 1998 and 1997:

Stock-Based Compensation

The Company grants options for a fixed number of shares to employees with an
exercise price equal to the fair value of the shares at the date of grant. The
Company accounts for stock option grants in accordance with APB Opinion No. 25,
Accounting for Stock Issued to Employees ("APB No. 25") and, accordingly,

</TABLE>

At June 30, 1998 the Company had net operating loss carryforwards of
approximately $4,755,400 and $719,000 available to offset future taxable Federal
and state taxable income, respectively. The carryforward amounts expire in
varying amounts between 2001 and 2013. The Company also has research and
development credits of $92,000 which begin to expire in 2001.

Due to the change in ownership provisions of the Tax Reform Act of 1986, net
operating loss carryforwards for Federal and state income tax reporting purposes
are subject to annual limitations. Should a change in ownership occur, net
operating loss carryforwards may be limited as to use in future years.

Stock Compensation Plans

The Company has various stock-based compensation plans, which are described
below. The Company applies the provisions of APB No. 25 and related
Interpretations in accounting for its plans. Accordingly, no compensation
expense has been recognized upon granting of options under its fixed stock
option and warrant plans. Had compensation cost for the Company's stock-based
compensation plans been determined based on the fair value at the grant dates

Stock Option Plans

The Company has various fixed stock option plans that provide for the granting
of incentive or non-statutory options to its key employees, non-employee members
of the Board of Directors, consultants and independent contractors. In the case
of incentive stock options, the exercise price may not be less than the fair
market value of the Company's stock on the date of the grant, and may not be
less than 110% of the fair market value of the Company's stock on the date of
the grant for any individual possessing 10% or more of the voting power of all
classes of stock of the Company. The options are generally exercisable
immediately upon grant and expire not later than 10 years from the date of
grant. Approximately 779,000 shares of common stock are reserved for future
issuance upon exercise of fixed options.

For purposes of pro forma disclosure, the fair value of each option grant is
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted average assumptions used for grants in 1998 and 1997,
respectively: risk-free interest rate of 6% and 6.5%; dividend yield of 0% and
0%; volatility of 58% and 47%; and a weighted average expected life of the
option of 4 years and 4 years.

Stock Warrant Plans

The Company has an officers and directors warrant compensation plan (the Plan)
under which warrants are granted at exercise prices established by the Board of
Directors. Warrants have historically been granted for a period of five years
with immediate vesting. Such terms, however, are at the discretion of the
Company's Board of Directors and may vary.

On December 8, 1995, the Company's board of directors established a five-year
warrant program (the Program), pursuant to which each of the Company's outside
directors was granted warrants to purchase 30,000 shares of the Company's common
stock at fair market value as of the date of grant. The warrants vest, ratably
over a five year period

6. Profit Sharing Plan

The Company has a 401(k) profit sharing plan covering all employees who have
completed one year of service, consisting of at least 1,000 hours of service,
and have attained the age of 21 years, unless otherwise excluded. The plan
permits eligible employees to contribute to the plan up to 20% of their pre-tax
earnings, up to the annual maximum. The Company may make qualified non-elective
contributions to employees not classified as highly compensated. Additionally,
the Company may make profit sharing contributions to qualifying participants on
a pro-rata basis. Qualified participants become fully vested in the profit
sharing contribution over a period of six years of service. The Company did not
make contributions to the plan in 1998 and 1997.

                                                                              14

Distribution Agreements

During September 1995, the Company entered into a distributorship agreement (the
Distributorship Agreement) with an unrelated company (Distributor), thereby
appointing the Distributor as the Company's exclusive world-wide distributor in
the field of interventional radiology and to supply the Distributor with
peripherally inserted central catheters (PICC Products). The transfer price to
the Distributor for PICC Products was fixed for the first two years of the
Distributorship Agreement and subject to revision thereafter by either party in
accordance with the terms of said agreement. The distributorship may become non-
exclusive in certain circumstances. The Distributorship Agreement is effective
through September 2000, at which time it may be renewed for an additional three
years unless sooner terminated. The Distributor Agreement also grants the
Distributor a three-year option to purchase certain property, plant and
equipment used in the development, manufacture and preparation of the PICC
Products and a paid-up irrevocable license to all related patent rights and
know-how related to the PICC Products at a purchase price equal to a percentage
of one year's sales of the PICC Products (as defined in the Distributorship
Agreement). The Distributor can exercise its purchase option in September 1998
or upon certain events.

During August 1994, the Company entered into an exclusive five-year distribution
agreement for the sale of intra-vascular catheters in certain western U.S.
states. The agreement provides certain termination privileges for the Company
and for the distributor. The Company's sales to this distributor represented 8%
and 9% of total product sales for 1998 and 1997, respectively.

Effective August 11, 1997, the Company entered into a distribution agreement
(Distribution Agreement), with an unrelated company (Distributor), thereby
appointing the Distributor as the Company's semi-exclusive distributor for
peripherally inserted central and midline catheters and related products and
accessories in the countries of the European Economic Union (EU), Australia,
Norway, Switzerland, Kuwait, Bahrain, Saudi Arabia, United Arab Emirates (UAE),
Yemen and Oman. The agreement is effective through August 2002.

                                                                              15

Manufacturing Agreement

During March 1996, the Company entered into a product development and supply
agreement (the Agreement) with an unrelated company (Seller), to manufacture and
sell tracheostomy and cricothyroidotomy products. The Agreement provided for the
assignment to the Company of certain patents issued to the former owners of the
Seller.

The Agreement requires the payment of certain royalties based on amounts derived
from the application of the then-relevant royalty percentage to the "gross sales
price" for all products utilizing the patented technology. The royalty
percentages are as follows:

   Period                                                            Percentage
-------------------------------------------------------------------------------
 
<S>                                                                   <C>
   March 1996 through February 1997                                     15%
   March 1997 through expiration of patents (ranging from December
    1999 through December 2007)                                         10%   
 
</TABLE>

Under the Agreement, royalty payments of 3% of the "gross sales price" shall
continue if a certain former owner of the Seller survives the expiration of the
patents and shall cease upon the death of the former owner. Royalty expense
relating to this agreement amounted to $33,985 and $18,322 in 1998 and 1997,
respectively.

The purchase price for the assignment of the patents was $60,000 which is
included in intangible assets at June 30,1998.

Operating Lease

The Company leases its corporate and manufacturing facility on a month to month
basis, subject to termination with not less than six months written notice by
either party. Rent expense was $147,704 and $144,408 in fiscal year 1998 and
1997, respectively.

                                                                              16

Year 2000 (unaudited)

Many existing computer systems and applications, and other control devices, use
only two digits to identify a year in the date field, without considering the
impact of the upcoming changes in the century. As a result, such systems and
applications could fail or create erroneous results unless corrected so that
they can process data related to the year 2000. The Company relies on its
systems, applications and devices in operating and monitoring all major aspects
of its business, including financial systems (such as general ledger, accounts
payable and payroll modules), customer services, infrastructure, networks and
telecommunications equipment and end products. The Company also relies, directly
and indirectly, on external systems of business enterprises such as customers,
suppliers, creditors, financial organizations, and governmental entities, both
domestic and international, for accurate exchange of data. The Company's current
estimate is that the costs associated with the year 2000 issue, and the
consequences of incomplete or untimely resolution of the year 2000 issue, will
not have a material adverse effect on the results of operations or financial
position of the Company in any given year. However, despite the Company's
efforts to address the year 2000 impact on its internal systems, the Company has
not fully identified such impact or whether it can resolve it without disruption
of its business and without incurring significant expense. In addition, even if
the internal systems of the Company are not materially affected by the year 2000
issue, the Company could be affected through disruption in the operation of the
enterprises with which the Company interacts.

                                                                              17
