PART I
ITEM 1. BUSINESS
GENERAL
Interpore(R) Cross International is a medical device company that
designs, manufactures and markets synthetic bone and tissue products and spinal
implant devices in the United States and internationally. Our bone biologics
products are comprised of Pro Osteon(R) bone graft substitute products and OEM
hydroxyapatite products. In the spine products category, we offer the
Synergy(TM) Spinal System, which is used to achieve spine fusions in patients
suffering from degenerative conditions and deformities of the spine.
RECENT DEVELOPMENTS
In February 1998, we entered into an agreement to merge with Cross
Medical Products, Inc. ("Cross"), a publicly traded Ohio-based worldwide
supplier of spinal implant systems used to treat degenerative conditions and
deformities of the spine. The stockholders of both companies approved the merger
on May 6, 1998 and Cross was merged with one of our subsidiaries on May 7, 1998.
Stockholders of Cross received 1.275 shares of our common stock for each share
of issued and outstanding Cross common stock. Accordingly, we exchanged
approximately 6.7 million shares of our common stock for all of the common stock
of Cross. We accounted for the merger as a pooling-of-interests.
In February 1998, our Board of Directors approved a proposal for
Interpore Cross to reincorporate from California to Delaware. The proposed
reincorporation was approved by our stockholders and was completed on May 6,
1998. We are incorporated under the name of Interpore International, Inc.,
however, following the merger we began doing business as Interpore Cross
International.
BUSINESS STRATEGY
Our merger with Cross created a medical device company with a unique
combination of spinal and bone graft technologies and with an expanded product
portfolio and combined distribution channels specifically addressing the
spine/orthopaedic market. Our combined product portfolio addresses two of the
fastest growing areas in this market - biomaterials and spinal implants.
Virtually all spine fusion procedures require the use of a bone graft, and our
complimentary product portfolio allows us to provide the spine surgeon with most
of the products needed in a spinal fusion surgery. Our strategy is to capture an
increasing share of these markets by leveraging the distribution channels which
both companies brought to the merger and by developing new products through our
combined biologic and implant design capabilities. In the future, we hope to
develop and commercialize biologic spinal implant devices that ultimately are
completely replaced by natural bone and that contain growth factors which cause
bone to grow more completely and quickly.
MARKET OVERVIEW
The market for bone graft materials and spinal implants is significant,
and is estimated to approximate $1 billion per year worldwide.
The number of bone graft procedures performed annually in the United
States is estimated to exceed 500,000. This includes a wide variety of
procedures, with approximately 53% of the procedures in the spine, 33% in other
orthopaedic procedures, and about 14% in maxillofacial applications. There are
currently three major categories of bone grafts: autograft, allograft, and bone
graft substitutes. In an autograft procedure, bone material is harvested from
another part of the patient's skeleton and grafted to the site of the bone
deficit. This second surgical procedure, harvesting the patient's own bone,
increases total operating time and expense, and can lead to complications such
as infection, chronic pain, deformity and excess blood loss. When an autograft
is not feasible or desirable, allograft bone, obtained from a cadaver, can be
used. While allograft bone is available from numerous bone banks, its use
carries the risks of implant rejection and transmission of infectious agents
such as hepatitis and
2
3
HIV. Also, allograft bone is not always readily available due to the storage,
processing and donor screening required. The third bone graft option is the use
of a bone graft substitute such as our Pro Osteon(R). We estimate that
approximately 53% of the U.S. bone graft procedures are autograft procedures,
24% are allografts, and 23% are bone graft substitutes.
The number of spinal fusion procedures performed annually in the United
States is estimated to exceed 300,000. Spinal implant devices are used by
surgeons to obtain fusion of vertebrae in areas of the spine affected by
degenerative diseases, deformities, trauma and tumors. Spinal implants are used
to restore the natural anatomy and stabilize the spine while fusion occurs, and
They assist in preventing the bone graft material from collapsing or migrating.
We estimate that approximately 35% of the spinal fusion procedures are performed
in the cervical (upper) spine, approximately 53% are performed in the lumbar
(lower) spine, and approximately 12% are performed in the thoracic (middle)
spine. Our current spinal implants address the lumbar and thoracic regions of
the spine.
PRODUCTS
Our products fall into two categories: bone biologics and spinal
implants.
Bone Biologics Products
Our bone biologics products are comprised of coralline-based bone graft
substitute products, OEM hydroxyapatite products, and products for collecting
growth factors to encourage bone growth. Our bone graft substitute and OEM
hydroxyapatite products are derived from coral using a proprietary manufacturing
process. See "Proprietary Rights" Under this process, the exoskeleton of marine
coral, which is made of calcium carbonate, is either partially or fully
converted to calcium phosphate. These biocompatible materials have
interconnected porosity, architecture and chemical composition similar to that
of human bone, and facilitate bone and tissue ingrowth. When blocks or granules
of these products are placed in a bone defect, they provide a lattice for the
patient's own bone to grow through and heal. Bone biologics products include:
Pro Osteon 500 Porous Bone Graft Substitute ("Pro Osteon 500"), Pro Osteon 200
Porous Bone Graft Substitute ("Pro Osteon 200"), Pro Osteon 500R Resorbable Bone
Graft Substitute ("Pro Osteon 500R"), Interpore 200(R) Porous Hydroxyapatite
Bone Void Filler ("Interpore 200"), orbital implants and AGF(TM) ("Autologous
Growth Factors(TM)).
Pro Osteon 500. Pro Osteon 500 was our first and is our largest selling
bone graft substitute product. It is distinguished from our other bone graft
products by the size of the pores within the material. Pro Osteon 500 uses a
specific genera of coral that results in an average nominal pore size of 500
microns, approximately the same as human cancellous bone. At the time it
received a PMA ("Premarket Approval") from the U.S. Food and Drug Administration
("FDA") in October 1992, Pro Osteon 500 was the first commercially available
bone graft substitute for orthopaedic applications in the United States. In
clinical studies, the use of Pro Osteon 500 was demonstrated, radiographically
and clinically, to have healing and complication rates comparable to autograft
procedures. We are is not aware of any material unfavorable results in the
clinical studies for Pro Osteon 500. Pro Osteon 500 is available in granular
forms and a wide variety of block configurations up to 30 cubic centimeters
("cc's") in total volume. With approximately $700 of material used in an average
procedure, Pro Osteon 500 provides an attractive alternative to autograft and
allograft bone graft materials. The FDA approved indication is for treatment of
certain metaphyseal defects as well as cysts and tumors in long bones. Outside
the United States, Pro Osteon 500 is approved for a very broad range of bone
graft applications.
Pro Osteon 200 and Interpore 200. Pro Osteon 200 and Interpore 200 are
derived from a specific genera of coral that results in an average nominal pore
size of 200 microns, thus is slightly stronger and more dense than Pro Osteon
500. It is available in granular forms and a wide variety of block
configurations up to 15 cc's in total volume. In the United States, Pro Osteon
200 and Interpore 200 are approved for use in oral surgery, periodontal defects,
craniofacial and orthognathic indications. Outside the United States, Pro Osteon
200 and Interpore 200 are approved for a very broad range of bone grafting
applications. Pro Osteon 200 is distributed by our domestic and international
sales organizations. Interpore 200 is distributed on an OEM basis by a single
customer under an exclusive distribution agreement.

Pro Osteon 500R. Pro Osteon 500R bone graft substitute is similar to Pro
Osteon 500, but it is resorbable, which means that it is completely replaced by
the patient's own bone. Pro Osteon 500R substantially resorbs within six months.
In many cases surgeons prefer that the bone graft substitute completely resorb
because they can better assess bone growth on x-rays. Also, many surgeons
believe that complete resorption improves biomechanical properties of the bone
graft area. We manufacture Pro Osteon 500R under a patented, modified version of
our manufacturing process in which conversion is interrupted before the material
is completely converted, yielding a composite of calcium carbonate and calcium
phosphate. The final product is composed primarily of calcium carbonate, the
more rapidly resorbing of the two materials, which is covered throughout the
interconnected porosity by a thin layer of calcium phosphate, the slower
resorbing of the two materials. The thin layer of calcium phosphate resorbs
slowly, allowing sufficient time for bony ingrowth, and once the calcium
phosphate layer is partially resorbed, the inner composition of calcium
carbonate resorbs much more quickly. Pro Osteon 500R is approved for a very
broad range of bone graft applications, including use in spinal procedures, both
in the U.S. and internationally. We expect that eventually Pro Osteon 500R will
become our largest selling bone graft substitute product.
Orbital Implants. Orbital implants are used to replace damaged or
diseased eyes, to replace existing artificial eyes that have extruded or
migrated and to replace existing artificial eyes to improve tracking and
movement. Since 1989, we have manufactured orbital implants for artificial eyes
using the same material found in Pro Osteon 500. We believe that these orbital
implants provide a superior alternative to other artificial eyes because the
implant is physically attached to the patient's soft tissue. Because of the
attributes of our material, the patient typically experiences integration of the
soft tissue into the orbital implant. The result is improved tracking of the
artificial eye with the patient's companion eye. We manufacture this product
solely on an OEM basis under a manufacturing and licensing agreement.
AGF (Autologous Growth Factors). Autologous Growth Factors are
concentrated growth factors derived from platelets in a patient's blood which
are used to encourage more complete and rapid bone growth in bone grafts. We are
the exclusive licensee, in the areas of bone and cartilage, of a technology that
produces and concentrates these growth factors. In this process, blood from the
patient is separated into different component layers using a device called a
cell saver, which is routinely available in the orthopedic surgery suite. The
layer of platelet-rich plasma is then processed through a proprietary filtering
technology which super-concentrates the platelets and fibrinogen. The platelets
release Platelet-Derived Growth Factor (PDGF) and Transforming Growth Factor
Beta (TGF-(beta)). The fibrinogen converts to fibrin, which generates a gel-like
material with favorable handling characteristics. The AGF can then be combined
with a bone graft material, such as Pro Osteon, and implanted at the site of the
bone deficit. AGF has been shown in animal studies to increase the amount of
bone growth in defects. We believe that AGF provides the surgeon with the growth
factors desired for faster and more complete bone graft healing that may be
safer and more economical than synthetic growth factors being developed by other
companies.
In the fourth quarter of 1998, we received 510(k) marketing clearance
from the FDA for the two key products used to collect AGF, the
UltraConcentrator(TM) Permeability Hemodialyzer and the Automated Processor. We
had limited sales of these products to specific evaluation centers in 1998. We
plan to commercially introduce AGF in the second quarter of 1999.
Spinal Implant Products
Synergy Spinal Implant System. The Synergy Spinal Implant System
consists of rods, hooks and screws that are attached to vertebrae adjacent to an
injured or defective area of the spine. The surgeon restores the natural anatomy
and the system stabilizes the patient's spine while fusion of two or more
vertebrae occurs. A bone graft material is typically used in a spine fusion
surgery, and the implanted spine system helps to prevent the bone graft material
from collapsing or migrating during fusion. The Synergy System is a "universal"
implant system that allows surgeons to treat both the thoracic (middle) and
lumbar (lower) portions of the spine, making it applicable to approximately 65%
of the instrumented spinal fusion surgeries performed in the United States. The
Synergy System is flexible, strong and easy for surgeons to use. It does not
demand that surgeons follow a single surgical protocol, rather, it provides
several options. Implants come in various sizes and types to meet the surgeon's
preferences and the patient's anatomy, providing a secure anatomic fit for
virtually any pathology. The Synergy
4
5
System features unique implant locking mechanism designs that, combined with the
use of nitrogen-strengthened stainless steel or titanium, allow surgeons to
assemble constructs of exceptional strength while keeping the profile extremely
low. Titanium implant systems are preferred in many foreign markets and are
being used increasingly in the United States because titanium allows magnetic
resonance imaging ("MRI") of the spinal area. The Synergy System was engineered
to be easy for surgeons to use, reducing surgical time and requiring less
manipulation. The screws and hooks are top tightening, the rods do not require
pre-loading of additional components, and all implants allow for free rod
rotation. The implants can be used in both anterior and posterior applications,
and are available in two sizes for adults and for children.
In 1992, we formed the Synergy System Advisors, a group of prominent
spine surgeons, that assisted in the development of the Synergy Spinal System.
We have agreements with the advisors under which we pay royalties ranging from
6.5% to 8% of net revenues generated from the sale of certain products within
the Synergy Spinal Implant System.
See "Certain Business Considerations - We are dependent on a few
products which may be rendered obsolete."
RESEARCH AND DEVELOPMENT
Our research and development department consists of 18 full-time
employees who conduct research and product development with respect to our bone
biologics and spinal implant products. We also engage outside consultants and
academic research facilities for assistance with our new product development and
will license technology from third parties under appropriate circumstances. We
plan to continue to use outside resources for product research. Our engineers
also assist in the design of manufacturing improvements and support validation
procedures for the FDA's requirements for Quality System Regulations ("QSR"),
Good Manufacturing Practices ("GMP") and ISO 9001, the quality management system
that is a regulatory requirement of the European Community. Our expenditures for
research and development were $3.7 million in 1998, $3.2 million in 1997 and
$2.7 million in 1996.
New Bone Biologics Products. There are a number of companies developing
bone graft materials that would compete with Pro Osteon. However, we believe
that significant revenue growth in this market requires the development of
products that stimulate or accelerate the growth of bone. In addition to AGF, we
are investigating the development of a recombinant human bone morphogenetic
fusion protein. The fusion protein is a growth factor that can be attached
specifically to Pro Osteon. This is a collaboration with university-based
consultants in molecular engineering and biochemistry. The studies are being
conducted at a leading research institute. The material is currently being
evaluated in animal studies, and initial results have been encouraging. The
inventors have applied for patent protection and have licensed rights to us. If
successful in preclinical studies, this product would require FDA approval of an
Investigational Device Exemption ("IDE") involving human clinical studies, and
therefore we can give no assurance concerning when or whether FDA approval to
market these products will be received.
Also in this area, Pro Osteon is being evaluated with a purified bone
protein derived from cows. This protein is manufactured by a strategic partner.
The strategic partner is currently testing the material in combination with Pro
Osteon in preclinical animal studies. This project would also require an IDE for
human clinical studies.
In addition to these projects, we are also reviving previous development
efforts for a polymer-reinforced Pro Osteon material. Increasing the strength of
our resorbable version of Pro Osteon in various configurations, combined with
AGF, holds much promise for potential use as a natural, resorbable alternative
to titanium and composite intervertebral cages currently available in the
market. Such a product would likely require an IDE for human clinical studies,
and therefore would be several years from the market, if developed at all.
New Spinal Implant Products. We are developing improvements to our
existing Synergy Spinal Implant System, as well as new products in the cervical
spine area which would make the Synergy System applicable to virtually all
spinal fusion procedures. We expect to apply for a Humanitarian Use Designation
("HUD") and a
5
6
Humanitarian Device Exemption ("HDE") for a titanium spine cage used for a
corpectomy, which is the removal of an entire vertebra due to a tumor. Use of
this device pursuant to the HDE would be limited to a maximum of 4,000
procedures per year. Other products under development include an intervertebral
cage and an adjustable length rod for our Synergy Spinal Implant System.
Other New Products. In August 1998, we received FDA 510(k) clearance to
market a bone plate system. The uniquely designed bone plates can be contoured,
allow screw placement at various angles to insure best fit, and feature screw
holes which can be adjusted. The plates are made of titanium, which provides for
MRI and CT (computer-aided tomography) compatibility. The approved indication is
for the treatment of internal fixation of pelvic fractures. We expect to launch
this new product in 1999.
CUSTOMERS, SALES AND MARKETING
The decision to use our products is made by the orthopaedic surgeon or
the neurosurgeon. We direct our domestic marketing efforts to the approximately
14,000 practicing orthopaedic surgeons in the United States in private practice,
hospitals and orthopaedic treatment centers. Of the 14,000 practicing
orthopaedic surgeons, there are approximately 2,000 fellowship trained spine
surgeons. In addition to the orthopaedic surgeons, we estimate that there are
approximately 1,000 neurosurgeons performing instrumented spine fusion
procedures.
Our domestic sales organization consists of a combination of direct
sales representatives and independent agents. Direct sales representatives are
employees while agents are independent contractors. There are currently 22
direct sales representatives and 35 independent agent organizations. We invoice
the customer directly, generally at list prices, and pay commissions to the
direct sales representatives and agents. See "Certain Business Considerations -
Possible Denial of Third Party Reimbursement." We provide consignment
inventories to our direct sales representatives, agents and hospitals. A Vice
President of North American Sales and four division managers manage the domestic
sales organization. We select these direct sales representatives and agent
organizations for their expertise in spinal implant, orthopaedic or medical
device sales, their reputation with the surgeon community and their sales
coverage within a geographic area. Each direct sales representative and agent
organization is given an exclusive sales territory for some or all of our
products and is subject to periodic performance reviews and sales and product
training. See "Certain Business Considerations - Risks Related to Conversion of
Sales and Marketing Forces."
Outside of the United States, we distribute products through independent
distributors. We have a Director of International Sales and two international
sales managers and have established distribution arrangements with 53
distributors in 43 countries. Our international sales represented approximately
23% of sales in 1998, 24% of sales in 1997 and 22% of sales in 1996. See
"Government Regulation" and "Certain Business Considerations - Dependence on
Foreign Markets."
In order to improve shipping efficiencies and service to our
international customers, in January 1998, we entered into an agreement with a
contract warehouse in the Netherlands to ship Pro Osteon products to customers
in countries outside of North America.
We participate in numerous professional meetings including the American
Academy of Orthopaedic Surgeons Meeting, the North American Spine Society
Meeting and the Annual Meeting of the Orthopaedic Trauma Association. We also
participate in scientific presentations and professional seminars at hospitals.
RAW MATERIALS AND MANUFACTURING
Coral is the primary raw material used to manufacture our bone graft
substitute products. The coral used in our products is sourced from two genera
located in a wide variety of geographic locations. We presently harvest coral in
tropical areas of the Pacific and Indian Oceans. We believe we have an adequate
supply of coral for the foreseeable future. Coral is covered under an
international treaty entitled Convention on International Trade of Endangered
Species of Wild Fauna and Flora, which regulates the import/export of raw coral
and products derived therefrom in approximately 140 nations around the world. To
date, the limitations imposed by this treaty have not
6
7
negatively affected our ability to source raw coral. See "--Government
Regulation" and "Certain Business Considerations - Dependence on Suppliers."
The manufacturing process for our bone graft substitute products
involves coral qualification and cutting, hydrothermal conversion, testing,
packaging and sterilization of the product, all of which, with the exception of
sterilization, are performed at our facilities. In the hydrothermal exchange
process, a chemical reaction is initiated whereby the calcium carbonate
exoskeleton of the coral is partially or fully converted to calcium phosphate.
This results in a biocompatible material which has interconnected porosity,
architecture and chemical composition similar to that of human bone.
Components for products used to collect AGF, which include the
UltraConcentrator Permeability Hemodialyzer and the Automated Processor, are
sourced from outside vendors. They are currently sole-sourced, but we believe
that we could locate alternative vendors for supply of these components.
Following the receipt of product at our facility, we conduct inspection, some
assembly, packaging and labeling operations. The disposable products are
sterilized by contract sterilization vendors.
Implantable grade stainless steel and titanium bar stocks are the
primary raw material used to manufacture our spinal implants. We purchase and
inventory these materials, which are available from several sources and
currently have a purchase order lead time of approximately two months, so that
we can best control the quality and consistency of material used to manufacture
our spinal implant products. We re-sell the raw material to our contracted
outside vendors for the manufacture of our spinal implants based on our
specifications. Following the receipt of product at our facility, we conduct
inspection, packaging and labeling operations. Our spinal implant products are
distributed in a non-sterile condition, which is customary in the spinal implant
market. See "-- Government Regulation."
COMPETITION
Orthopaedic Bone Graft Substitute Market. Our synthetic bone products
compete with natural bone obtained from autograft procedures, cadaver bone
obtained from allografts and with other synthetic bone products. Autograft and
allograft bone have been used for graft material for a much longer period of
time than synthetic bone graft materials, and in order to maintain and increase
our future sales of Pro Osteon, we will have to continue to demonstrate to the
medical community the surgical and patient advantages, safety, efficacy, cost
effectiveness and clinical results of Pro Osteon. We estimate that synthetic
bone products, including demineralized cadaver bone, currently account for
approximately 23% of the total U.S. bone graft procedures. Competitive synthetic
bone products include: Grafton(R) demineralized bone products from Osteotech,
OsteoSet(TM) calcium sulfate from Wright Medical Technology, DynaGraft
demineralized bone products from GenSci Regeneration Technologies, Norian SRS
from Norian, as well as other synthetic bone products used in non-orthopaedic
applications. Several other companies are pursuing additional synthetic bone
graft materials for orthopaedic applications which could ultimately compete with
Pro Osteon in the United States.
Growth Factors. There is significant development activity ongoing that,
if successful, would potentially produce products competitive with our AGF
system. Genetics Institute, Inc. has a recombinant human bone morphogenetic
protein (rhBMP-2) in human clinical studies. Creative Biomolecules also has a
recombinant human bone morphogenetic protein (OP-1), which is in human clinical
studies under an FDA-approved IDE. Sulzer Orthopedics Biologics, a subsidiary of
SulzerMedica of Switzerland, has an extract of bovine (cow)-derived bone growth
protein that is in preclinical animal studies and may be in clinical evaluation.
Spinal Implant Market. Many companies compete in the spinal implant
market and competition is intense. We believe that our largest competitors in
the United States offering spinal implants are Sofamor Danek Group, Inc., a
subsidiary of Medtronic, and Acromed, Inc., a subsidiary of DePuy, each of which
has substantially greater sales and financial resources. We also compete with
many other companies that offer similar products. Other companies have developed
and are marketing products based on technologies that are different from ours,
including spinal fusion cages, spinal implants designed to be used with
minimally invasive or laparoscopic surgery, and allograft bone dowels.
7
8
We compete in all of our markets primarily on the basis of product
performance and price, as well as customer loyalty and service. See "Certain
Business Considerations - Rapid Technological Change and Intense Competition."
GOVERNMENT REGULATION
Our products are regulated by the FDA under the federal Food, Drug and
Cosmetic Act, as well as other federal, state and local governmental authorities
and similar regulatory agencies in other countries. The FDA permits commercial
distribution of a new medical device only after the FDA has cleared a 510(k)
premarket notification or has approved a Premarket Approval application for such
medical device. In general, the FDA will clear marketing of a medical device
through the 510(k) premarket notification process if it is demonstrated that the
new product is substantially equivalent (in terms of safety, efficacy and
intended use) to certain 510(k) cleared products which are already commercially
available and legally sold on the market.
The PMA approval process is lengthier and more burdensome than the
510(k) premarket notification process. The PMA process generally requires
detailed animal and clinical studies, as well as manufacturing data and other
information. If clinical studies are required by the FDA, an IDE is also
required. An IDE restricts the investigational use of the device to a limited
number of investigational sites, investigators and patients. Its purpose is to
prove safety and efficacy of the device. FDA approval of a PMA application
indicates that the FDA concurs that a device has been scientifically proven,
through the completion and submission of animal data, a completed IDE and other
pertinent information, to be safe and effective for its intended use.
In October 1992, we received FDA approval to market Pro Osteon 500 for
certain defects in the wide part of long bones. We subsequently received FDA
approval to market it in granular forms and a wide variety of block
configurations up to 30 cc's in total volume, and for additional indications
including the treatment of cysts and tumors in long bones. Our Pro Osteon 200
and Interpore 200 were cleared for marketing for certain oral surgery,
periodontal defects, craniofacial and orthognathic indications through 510(k)
premarket notifications. Orbital implants were also cleared through 510(k)
notification by a third party.
In July 1997, the FDA cleared the use of a competitive synthetic bone
graft substitute product with a 510(k). Prior to clearance of this device,
companies were required to obtain marketing approval from the FDA for bone graft
substitutes via the PMA process. It is possible that some clearances of other
bone graft substitute products may now be obtained through the less burdensome
510(k) premarket notification process. This may increase competition. In
September 1998, we received a 510(k) clearance from the FDA for our Pro Osteon
500R resorbable bone graft substitute product. The approved indications include
use in bony voids or gaps of the skeletal system, such as the extremities, spine
and pelvis.
In December 1998, we received FDA 510(k) clearances for the two key
products used to collect AGF, the UltraConcentrator Permeability Hemodialyzer
and the Automated Processor.
Our current spinal implant devices require 510(k) marketing clearance
from the FDA. We received 510(k) clearance from the FDA to market the anterior
portion of the Synergy System in October 1994 and for the posterior portion of
the system in July 1995. In September 1996, we developed a titanium version of
the Synergy Spinal Implant System for international distribution. We received
FDA marketing clearance for the anterior portion of the titanium version in
October 1995 and the posterior portion in January 1997.
We are registered as a medical device manufacturer with the FDA, with
state agencies such as the Food and Drug Branch of the California Department of
Health Services (the "California DHS") and with the European Community ("EC").
These agencies inspect our facilities from time to time to determine whether we
are in compliance with various regulations relating to medical device
manufacturing, including the FDA's QSR regulation and ISO 9001, which govern
design, manufacturing, testing, quality control, sterilization and labeling of
medical devices. We believe we are in compliance with the regulations
established by these agencies applicable to our business. The EC Notified Body,
the FDA and the California DHS have inspected our manufacturing facilities and
quality assurance procedures in the past.
8
9
With respect to our bone graft substitute products, we must also comply
with the requirements of the Convention of International Trade of Endangered
Species of Wild Fauna and Flora ("CITES"). This is an international agreement
signed by approximately 140 nations which regulates the import and export of
products which are derived from endangered wildlife. Although the coral we use
is not an endangered species, all harvested coral is subject to regulation under
CITES. As a result, we must register and obtain licensure from the U.S.
Department of Fish and Wildlife for both the import of raw coral and the export
of finished product. We maintain several years' supply of coral to minimize the
risk of supply interruptions. Because each shipment of product exported outside
of the United States or its possessions requires individual permitting, and also
to improve shipping efficiencies and service to our international customers, we
entered into an agreement with a contract warehouse in the Netherlands for the
purpose of international distribution of our products. See "Certain Business
Considerations - Dependence on Suppliers."
We must also comply with registration requirements of foreign
governments and with import and export regulations when distributing its
products to foreign nations. Each foreign country's regulatory requirements for
product approval and distribution are unique and may require the expenditure of
substantial time, resources and effort to obtain and maintain approvals for
marketing. In September 1995, we received approval to use the "CE" mark for our
entire line of orthopaedic and oral/maxillofacial synthetic bone graft
materials. We received approval to use the "CE" mark for our spinal implant
systems in 1998. The CE mark indicates that the products are approved for sale
within 18 countries in the EC (European Community) and EFTA (European Free Trade
Association) and that we are in compliance with the ISO 9001 and EN 46001
standards which govern medical device manufacturers that are marketing products
in Europe. The CE mark is now also accepted by several countries outside of the
EC. See "Certain Business Considerations - FDA and Other Government Regulation."
PROPRIETARY RIGHTS
Bone Biologics Materials. In September 1976, we were granted a license
with respect to five United States patents and related foreign patents covering
the technology relating to our manufacturing process. The license provided us
with exclusive rights to manufacture and distribute the licensed products until
expiration of the patents. The most significant patent concerned the right to
manufacture a hydroxyapatite bone graft substitute material from marine coral,
and it expired in December 1994. The remaining patents expired in 1997. We do
not anticipate any significant impact on our business as a result of the
expiration of the patents for two reasons. First, we believe the lengthy FDA
approval process and our proprietary manufacturing processes would discourage a
company from attempting to develop a coralline hydroxyapatite bone graft
product. Second, our new resorbable Pro Osteon 500R is protected by two U.S.
patents.
We own six United States patents related to improvements on the process
for manufacturing biomaterials for bone reconstruction: two of the patents
relate to Pro Osteon 500R, and four of the patents relate to a non-coral based
synthetically produced porous hydroxyapatite. These patents expire between 2006
and 2013.
Spinal Implant Products. We have eight United States patents related to
our spinal implant systems which expire between 2006 and 2014. We have been
granted licenses on two additional United States patents. These patents and
licenses concern various aspects of the Synergy Implant System including the
bone anchor, the rod/anchor interface, instrumentation and transverse
connectors.
Patents and Personnel. As part of our ongoing research, development and
manufacturing activities, we have a policy of seeking patent protection. Patents
relating to particular products, uses or procedures, however, do not preclude
other manufacturers from employing alternative processes or from successfully
marketing substitute products. We believe that although patents often are
necessary to protect our technology and products, the lengthy FDA approval
process and certain manufacturing processes are more significant barriers to
entry. Moreover, much of the proprietary technology and manufacturing processes
developed by us reside in our key scientific and technical personnel and such
technology and processes are not easily transferable to other scientific and
technical personnel. The loss of the services of key scientific, technical and
manufacturing personnel could have a material adverse effect on our business and
results of operations. See "Certain Business Considerations - Challenges to
Patents and Proprietary Rights."

EMPLOYEES
As of March 1, 1999, we had 120 full-time employees, of whom 49 were
engaged in marketing and sales, 27 in manufacturing, 16 in regulatory affairs
and quality assurance, 10 in general administration and finance and 18 in
research and development. None of these employees is represented by a union, and
we have never experienced a work stoppage. We consider our relations with our
employees to be good.
CERTAIN BUSINESS CONSIDERATIONS
This Annual Report on Form 10-K contains forward-looking statements
which involve risks and uncertainties. Actual results may differ significantly
from the results discussed in the forward-looking statements. Factors that might
cause such a difference include, but are not limited to, those discussed below
and elsewhere in this Annual Report on Form 10-K.
We are dependent on a few products which may be rendered obsolete. We
anticipate that most of our revenue growth in the future, if any, will come from
our spinal implant products and from our bone biologics products. There can be
no assurance that we will be successful in increasing our sales. Our current
primary product development efforts involve a cervical version of the Synergy
Spinal Implant System, a spinal implant cage and resorbable and osteoinductive
bone graft materials. There can be no assurance that we will be successful in
marketing our current products or in developing and marketing our new products
or that a competitor will not introduce a superior product or technology that
would render our products obsolete. In any event, we may not be able to produce
sufficient sales to achieve profitability.
Product Liability, Litigation and Insurance. The spinal implant industry
has been historically litigious and we face an inherent business risk of
financial exposure to product liability claims. Since our spinal products are
often permanently implanted in the human body, manufacturing errors or design
defects could result in injury or death to the patient, and could result in a
recall of the our products and substantial monetary damages. Prior to the
merger, Cross had been named as a defendant in approximately 797 cases alleging
principally that it participated in an industry-wide conspiracy to market
pedicle screw implants, although none of the remaining lawsuits involve any of
our products. We anticipate that additional similar suits will be filed in the
future. We cannot assure you that we will not experience losses to the extent
that our insurance coverage is not adequate to cover the cost of defending these
and similar suits that may be filed in the future or the cost of settling such
claims or paying any adverse judgments. Such insurance is expensive and may not
be available in the future on acceptable terms, or at all. See "Legal
Proceedings."
Challenges to Patents and Proprietary Rights. We rely on a combination
of patents, trade secrets and nondisclosure agreements to protect our
proprietary intellectual property. There can be no assurance that pending patent
applications will result in issued patents, that patents issued to or licensed
by us will not be challenged or circumvented by competitors or that such patents
will be found to be valid or sufficiently broad to protect our technology or to
provide us with any competitive advantage. Third parties could also obtain
patents that may require licensing for the conduct of our business, and there
can be no assurance that the required licenses would be available. We also rely
on confidentiality agreements with certain employees, consultants and other
parties to protect, in part, trade secrets and other proprietary technology.
There can be no assurance that these agreements will not be breached, that we
will have adequate remedies for any breach, that others will not independently
develop substantially equivalent proprietary information or that third parties
will not otherwise gain access to our trade secrets and proprietary knowledge.
See "Proprietary Rights."
Rapid Technological Change and Intense Competition. We compete with many
companies, some of which have access to greater financial and other resources.
Furthermore, the medical device market is characterized by intense development
efforts and rapidly advancing technology. Our present and future products could
be rendered obsolete or uneconomical by technological advances by one or more of
our current or future competitors or by
10
11
alternative therapies such as drugs. Our success will depend, in large part,
upon our ability to anticipate and keep pace with such advances. Competitive
market forces may also adversely affect the prices at which we sell our
products. In order to increase our future sales of bone biologics and spinal
implant products, we will have to continue to demonstrate to the medical
community the surgical and patient advantages, safety, efficacy and cost
effectiveness. See "Competition."
Possible Denial of Third-Party Reimbursement. Our products are purchased
by hospitals, doctors and other health care providers who are reimbursed for the
health care services provided to their patients by third-party payors, such as
governmental programs (e.g., Medicare and Medicaid), private insurance plans and
managed care programs. These third-party payors may deny reimbursement if they
should determine that a device used in a procedure was not used in accordance
with cost-effective treatment methods, as determined by such third-party payor,
or was used for an unapproved indication. Also, third-party payors are
increasingly challenging the prices charged for medical products and services.
There can be no assurance that our products will be considered cost-effective by
third-party payors, that reimbursement will be available or, if available, that
the third-party payors' reimbursement policies will not adversely affect our
ability to sell our products profitably.
Risks related to Conversion of Sales and Marketing Forces. We have
recently made significant changes to our domestic distribution channels for the
sale of our products. We have terminated certain under-performing direct sales
representatives and independent agents, replacing them with new direct sales
representatives and independent agents. Once the merger was completed,
Interpore's and Cross' product portfolios were combined, and as a result we
found that we could attract independent agents that desired our complementary
product portfolio and that possessed strong surgeon relationships, an important
factor for competing in this industry. Therefore, we expect to increase our use
of independent agents for the domestic distribution of both bone biologics and
spine products. Independent commissioned sales agents typically market other
medical devices for a variety of manufacturers. There can be no assurance that
we will be able to develop an effective distribution network or that our sales
force will be able to successfully sell our products.
FDA and Other Governmental Regulation. The medical devices we
manufacture and market are subject to rigorous regulation by the FDA and
numerous other federal, state and foreign governmental authorities. The process
of obtaining regulatory approvals to market a medical device, particularly from
the FDA, can be costly and time-consuming, and there can be no assurance that
such approvals will be granted on a timely basis, if at all. The regulatory
process may delay the marketing of new products for lengthy periods and impose
substantial additional costs or it may prevent the introduction of new products
altogether. Moreover, foreign governmental authorities have become increasingly
stringent and we may be subject to more rigorous regulation by foreign
governmental authorities in the future. All products and manufacturing
facilities are subject to continual review and periodic inspection by the FDA.
The discovery of previously unknown problems with our company or our products or
facilities may result in product labeling restrictions, recall, or withdrawal of
the products from the market. In addition, the FDA actively enforces regulations
prohibiting the promotion of medical devices for unapproved indications. We
prohibit off-label promotion of our products. Material violation of such
regulations could lead to the imposition of injunctions, suspensions or loss of
regulatory approvals, product recalls, termination of distribution, or product
seizures. In the most egregious cases, criminal sanctions or closure of our
manufacturing facility are possible.
Dependence on Suppliers. We do not manufacture the components for our
spinal implants and instruments or our products used to collect AGF and we are
dependent upon several suppliers for the production of such components. In the
event that we are unable to obtain components, or obtain such components on
commercially reasonable terms, we may not be able to manufacture or distribute
our products on a timely and competitive basis, or at all. We must comply with
the requirements of the Convention of International Trade of Endangered Species
of Wild Fauna and Flora ("CITES"). As a result, we must register and obtain
licensure from the U.S. Department of Fish and Wildlife for both the import of
raw coral and the export of finished product. In the future, regulations could
make the import or export of coral or coral-derived products prohibitive and
could interrupt our ability to supply product. We cannot assure you that our
supply of raw coral is sufficient, that we will be able to obtain sufficient
quantities of coral in the future or that future regulations will not prohibit
its use altogether.
11
12
Dependence on Foreign Markets. A substantial portion of our net revenue
is generated from outside North America. We expect that such sales will continue
to account for a significant portion of our net revenue in the future. Our
international operations are subject to other inherent risks, including the
following:
- fluctuations in currency exchange rates;
- regulatory and product approval requirements;
- tariffs and other trade barriers;
- greater difficulty in accounts receivable collection and longer
collection periods;
- reimbursement approvals (both government and private);
- difficulties and costs of staffing and managing foreign operations and
distributors; o potentially adverse tax consequences;
- reduced protection for intellectual property rights in some countries,
including restrictions on repatriation of earnings;
- burdens of complying with a wide variety of foreign laws;
- the impact of recessions in economies outside the United States;
- political and economic instability; and
- seasonal reductions in business activity during the summer months in
Europe and other parts of the world.
If we fail to successfully market and sell our products in international
markets, our business, financial condition, results of operations, and cash
flows could be materially and adversely affected.
Volatility of Market Price. Market prices for securities of small-cap
biomaterials and medical device companies have historically been highly
volatile. Our quarterly operating results, the announcement of our technological
innovations or new products, governmental regulation, timing of regulatory
approvals, developments related to our patents or proprietary rights, or
publicity regarding actual or potential malfunctions or regarding our
competitors' products may cause the market price of our common stock to
fluctuate substantially.
Year 2000 Risk. The Year 2000 compliance issue results from the
inability of systems that utilize computer programs to differentiate between the
year 1900 and the year 2000. The Year 2000 issue not only affects computer
hardware and software, but also can affect equipment used in our operations, and
extends to the systems of outside suppliers and customers, upon which we rely.
Failure to address the Year 2000 issue on a timely basis, or at all, for
critical programs used by us could result in system failures or miscalculations,
which could have material adverse effect on our business, results of operations,
financial condition, and cash flows.
ITEM 2. PROPERTIES
We lease a 36,830 square foot facility in Irvine, California. This
facility was approved in March 1994 by the FDA for the manufacture of Pro
Osteon. The average annual lease expense over the ten year term of the lease,
which expires January 31, 2003, is $387,000. The lease provides a right to
extend the term for an additional five years at the fair market lease rate of
the facility on the extension date, but not less than the rate we paid during
the month immediately preceding the commencement of the extension period. We
also lease a 2,700 square foot facility in Santa Ana, California to provide
additional warehousing, an 1,800 square foot prototype machine shop in Irvine,
California and a sales office with approximately 200 square feet in Miami,
Florida. We believe the facilities will be adequate to serve our operational
needs through 1999. Additional space may be needed subsequent to 1999 depending
on our growth, and there can be no assurance that such space in reasonable
proximity to our main facility will be available.
We also lease a 27,680 facility in Dublin, Ohio. The lease term began on
April 1, 1996 and terminates on June 1, 2001. This facility was almost entirely
vacated in 1998 upon the relocation of operations to Irvine, California. We are
attempting to sublease this facility.

ITEM 3. LEGAL PROCEEDINGS
Cross and a number of other spinal implant manufacturers were named as
defendants in various products liability lawsuits alleging injuries from spinal
implants supplied by Cross and others. All such lawsuits were consolidated for
pretrial proceedings in the Federal District Court for the Eastern District of
Pennsylvania and, on February 22, 1995, class certification was denied. This
forced the plaintiffs to file individual, rather than class action suits. Over
1,100 such suits were initially filed; however, Cross was dismissed from these
lawsuits for failure of the plaintiffs to state a viable claim. A large number
of plaintiffs filed new lawsuits against Cross and others alleging, in addition
to damages from spinal implants, a conspiracy among manufacturers, physicians
and other spinal implant industry members to defraud the public and market
products without the proper regulatory approvals. Cross was named as a
defendant, among others, in approximately 797 such lawsuits. We cannot estimate
precisely the number of such lawsuits that may eventually be filed or in how
many lawsuits Cross will be named as a defendant. In approximately 235 of these
cases, which involved products manufactured by Acromed, another spinal implant
manufacturer, Cross has been dismissed as a defendant. Cross has also been
dismissed as a defendant from approximately 79 additional cases. Of the
remaining conspiracy cases, none involve products manufactured by Cross.
The conspiracy cases remain coordinated for pretrial purposes only.
Plaintiffs in the conspiracy cases typically seek relief in the form of monetary
damages, often in unspecified amounts. While the aggregate monetary damages
eventually sought in all of such individual actions are substantial and exceed
the limits of Cross' products liability insurance policies, we believe that
Cross has affirmative defenses, and that these individual lawsuits are otherwise
without merit.
The lawsuits are being defended by Cross' insurance carrier, in some
cases under a reservation of rights. Cross maintains claims made products
liability insurance policies with $5 million of coverage both per occurrence and
in the aggregate. We believe that we have adequate insurance for our businesses,
however, there can be no assurance that the $5 million per policy year limit of
coverage will be sufficient to cover the cost of defending all lawsuits or the
payment of any amounts that may be paid in satisfaction of any settlements or
judgments. Further, there can be no assurance that Cross will continue to be
able to obtain sufficient amounts of products liability insurance coverage at
commercially reasonable premiums. Future operating results could be materially
adversely affected by the cost of defending litigation or the formal resolution
of pending cases or future claims, whether or not such defense costs, cases or
claims are covered by insurance.
Aside from the conspiracy litigation, the nature of our business
subjects us to products liability and various other legal proceedings from time
to time. In the opinion of management, the amount of ultimate liability with
respect to any known proceedings or claims, excluding the conspiracy litigation,
will not materially affect our financial position or results of operations. See
"Certain Business Considerations - Product Liability, Litigation and Insurance."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION
DESCRIPTION OF BUSINESS
Interpore International, Inc. ("Interpore Cross") designs, manufactures
and markets synthetic bone and tissue products and spinal implant devices. Our
merger with Cross Medical Products, Inc. ("Cross") in May 1998 has significantly
increased our focus on the spine market, one of the fastest growing areas within
the orthopaedic marketplace. We report our sales in two product categories: bone
biologics and spinal products.
Bone biologics are comprised of Pro Osteon(R) bone graft substitute
products and OEM hydroxyapatite products. These products are derived from coral
and serve as a lattice for new bone growth when implanted into a bone defect.
The unique, interconnected porous architecture of the product is a key to its
success as a bone graft substitute. Bone graft substitutes such as Pro Osteon
offer distinct advantages over autografts and allografts. In an autograft, bone
is taken from another part of the patient's body, and frequently creates pain,
longer recovery, and risk of other complications for the patient. An allograft,
or bone taken from a cadaver, carries the risk of implant rejection or disease
transmission. We recently introduced our new AGF(TM) (Autologous Growth
Factors(TM)) related products, which can be used with a bone graft material,
such as Pro Osteon, to encourage bone growth. AGF is comprised of concentrated
growth factors derived from platelets in the patient's own blood during the
surgical procedure.
In the spine products category, we offer the Synergy(TM) Spinal System,
which is used to facilitate spine fusions in patients suffering from
degenerative conditions and deformities of the spine. These conditions
frequently cause severe pain and loss of muscle function in patients. The
Synergy System is comprised of titanium or stainless steel hooks, rods and
screws and the instruments required for the surgeon to assemble a construct
which restores the natural anatomy, keeping it immobilized while a bone graft
eventually fuses the vertebrae naturally.
Prior to the merger, we distributed our bone biologics products through
employee direct sales representatives and commissioned independent agents in the
U.S., and through stocking distributors outside the U.S. In the U.S. we had been
converting to direct representatives because we believed, with only bone graft
products in our product portfolio, we could get more focused sales time compared
to independent agents carrying other product lines. Cross was distributing its
products in the U.S. solely through independent agents, and internationally
through stocking distributors. In the U.S., both companies' sales forces were
calling directly on the same decision-maker - the orthopaedic/spine surgeon,
providing part of the rationale for the merger. Once the merger was completed,
the respective companies' product portfolios were combined, and as a result we
found we could attract independent agents that desired our complementary product
portfolio and that possessed strong surgeon relationships, an important factor
for competing in this industry. Therefore, we expect to increase our use of
independent agents for the domestic distribution of both bone biologics and
spine products.
Currently, the surgeon is the key decision maker with respect to the
purchase of our products, and the hospital pays our invoices directly. However,
for many other medical device products, the purchasing decision has been assumed
by hospital purchasing departments, buying groups or managed care organizations.
Also, for some other medical device products, insurance companies and Medicare
have refused to reimburse the hospital, or the company directly in the case of
direct-to-insurer billing by the company, and therefore reimbursement becomes an
issue. These factors have not been an issue for us to-date. However, in the
future there can be no assurance that the decision-making responsibility will
not shift from the surgeon, or that reimbursement will not become an issue
affecting our revenues. Other factors potentially affecting continued revenue
growth include: the pricing practices of our competitors, competitive new
product introductions, and our ability to continue to attract and retain
qualified direct sales representatives, independent agents, and distributors.
Sales to our OEM customers and our international distributors are affected by
their purchasing practices, and in the case of international sales, by the
financial capacity of our distributors and the economic conditions in their
countries. Continued revenue growth may also depend upon our ability to
successfully introduce new products or product improvements. See "Certain
Business Considerations" in our 1998 Annual Report on Form 10-K.

SIGNIFICANT EVENTS
In February 1998, we entered into an agreement to merge with Cross, a
publicly traded Ohio-based worldwide supplier of spinal implant systems used to
treat degenerative conditions and deformities of the spine. The shareholders of
both companies approved the merger on May 6, 1998 and it became effective on May
7, 1998. We exchanged approximately 6.7 million shares of our common stock for
all of the common stock of Cross. We accounted for the merger as a
pooling-of-interests.
In April 1997, we entered into an agreement to sell our dental business
to Steri-Oss Inc. of Yorba Linda, California. In May 1997, the sale was
completed, and we received an initial cash payment of $1.5 million. In March
1998, we received a deferred cash payment of $749,000. As part of the
transaction, Interpore Cross and Steri-Oss negotiated a distribution agreement
under which we manufacture and provide Interpore 200(R) Porous Hydroxyapatite
Bone Void Filler for distribution by Steri-Oss in the dental market. In the
quarter ended June 30, 1997, we recorded a net charge of $617,000 as a result of
the transaction, including associated costs.
In March 1997, Cross entered into an agreement to sell its recovery
products segment for $8.2 million in cash and the assumption of $5.0 million of
debt and other liabilities. The buyer also acquired 30,000 shares of Cross'
common stock for $242,000.

1998 Compared to 1997
For the year ended December 31, 1998, net sales of $30.2 million were
$1.8 million or 6.3% higher than net sales of $28.4 million for the previous
year. However, 1997 included $1.7 million of sales from the dental business
which was sold in May 1997. Excluding dental products, net sales increased $3.5
million or 13.0% in 1998 compared to 1997. The following table presents sales by
category (in thousands):
Year ended December 31, Change
------------------------- ------------------
1998 1997 Amount %
------- ------- ------- ------
Bone biologics product sales ......... $14,842 $13,805 $ 1,037 7.5%

Total net sales ...................... $30,209 $28,429 $ 1,780 6.3%
======= ======= ======= ======
Sales of bone biologics products increased by $1.0 million or 7.5% to
$14.8 million for the year ended December 31, 1998 compared to $13.8 million for
the year ended December 31, 1997. Pro Osteon sales increased by $1.7 million,
due to the introduction of the resorbable version, Pro Osteon 500R, in the
fourth quarter of 1998, along with improved distribution following the merger
and resultant consolidation of sales forces. OEM sales, which are dependent upon
the ordering patterns of two customers, decreased by $624,000 in 1998 versus
1997.
Sales of spinal implant products increased in the year ended December
31, 1998 by $2.4 million or 19.0% to $15.4 million, compared to $12.9 million
for the year ended December 31, 1997. The increase reflects continued market
penetration of this relatively new system, aided by the improved distribution
and greater domestic territory coverage following the merger.
Total domestic sales of bone biologics and spinal products increased
15.6% or $3.1 million to $23.1 million for the year ended December 31, 1998
compared to $20.0 million for the same period of 1997. International sales
increased $363,000 or 5.4% to $7.1 million for the twelve months ended December
31, 1998 from $6.7 million for the same period of 1997.
For the year ended December 31, 1998, gross margin as a percentage of
sales was 71.7% compared to 68.0% for the year ended December 31, 1997. The 1997
gross margin was lower as a result of an inventory valuation adjustment of
$925,000 that was recognized for spinal products that became obsolete or
slow-moving due to the widespread acceptance of certain improvements and
modifications to the Synergy Spinal System. Additionally, domestic sales, which
generally have a higher gross margin than international sales, comprised a
greater percentage of total sales in 1998 than in 1997.
Total operating expenses for the year ended December 31, 1998 increased
by $4.4 million or 22.1% to $24.5 million compared to total operating expenses
of $20.1 million during the same period of 1997. The increase in operating
expenses was primarily due to $5.0 million of merger-related expenses,
restructuring charges and non-recurring charges incurred in 1998. Excluding
these charges and the 1997 loss on the sale of the dental business, total
operating expenses remained relatively level between the two periods. Research
and development expenses increased by 13.4% or $430,000 in 1998 as a result of
increased spinal product development efforts and increased regulatory expenses
related to obtaining FDA clearances for Pro Osteon 500R and AGF associated
products. Selling and marketing expenses in 1998 increased $251,000 or 2.2%
compared to 1997 due primarily to increased commissions on higher domestic sales
in 1998, offset partially by the elimination of selling and marketing expenses
related to the dental business. General and administrative expenses decreased by
$648,000 or 13.8% in 1998, primarily the result of cost reductions following the
sale of the dental business and the merger.
18
19
The $60,000 or 10.6% decrease in net interest and other income relates
to a reduction in interest income due to lower cash, cash equivalents and
short-term investments. The decrease was partially offset by increased royalty
income.
Limited income tax provisions were recorded during 1998 due to the
utilization of net operating loss carryforwards.
1997 Compared to 1996
For the year ended December 31, 1997, net sales of $28.4 million were
$60,000 or .2% lower than sales of $28.5 million for the previous year. However,
excluding dental product sales, net sales increased $5.4 million or 25.2%. The
following table presents sales by category (in thousands):
Year ended December 31, Change
------------------------- ------------------
1997 1996 Amount %
------- ------- ------- -----
Bone biologics product sales .......... $13,805 $12,773 $ 1,032 8.1%
Spinal implant product sales .......... 12,918 8,572 4,346 50.7%

======= ======= ======= =====
Sales of bone biologics products increased by $1.0 million or 8.1% to
$13.8 million for the year ended December 31, 1997, compared to $12.8 million
for the year ended December 31, 1996. This increase is attributable primarily to
a 2.0% increase in domestic Pro Osteon product sales and a 109.0% increase in
international Pro Osteon product sales. Sales of spinal implant products
increased in the year ended December 31, 1997 by $4.3 million or 50.7% to $12.9
million compared to $8.6 million for the year ended December 31, 1996. This
increase was primarily a result of increased penetration into the spinal implant
market as Cross continued to increase its distribution network and the number of
surgeons using the Synergy Spinal System. Also, in January 1997, the posterior
portion of the titanium version of the Synergy Spinal System received FDA
marketing clearance for sale in the United States.
Sales of dental products declined by $5.4 million or 76.1% from $7.1
million in 1996 to $1.7 million in 1997, reflecting the discontinuance of dental
product sales effective April 1997.
Total domestic sales of bone biologics and spinal products increased
21.8% or $3.6 million to $20.0 million for the year ended December 31, 1997
compared to $16.4 million for the same period of 1996. International sales
increased by $1.8 million or 36.5% to $6.7 million for the twelve months ended
December 31, 1997 from $4.9 million for the same period of 1996.
For the year ended December 31, 1997, the gross margin improved to 68.0%
of sales from 66.7% of sales for the twelve months ended December 31, 1996. The
improvement reflects the discontinuance of dental product sales which had lower
gross margins than our bone biologics and spinal implant products. This was
partially offset by the inventory valuation adjustment of $925,000 that was
recognized for products that became obsolete or slow-moving due to the
widespread acceptance of certain improvements and modifications to the Synergy
Spinal System.
Total operating expenses for the year ended December 31, 1997, which
included a $617,000 loss on the sale of the dental business, increased by
$699,000 as compared to the same period of 1996. Research and development
expenses increased by 19.8% or $532,000 as a result of increased spinal product
development efforts. Selling and marketing expenses decreased 8.8% or $1.1
million compared to the twelve months ended December 31, 1996 due to the
elimination of selling and marketing expenses directly related to the dental
business partially offset by increased commissions on higher domestic sales.
General and administrative expenses increased by
19
20
$664,000 or 16.5%, primarily the result of product liability insurance premiums
on increased sales, partially offset by cost reductions following the sale of
the dental business.
The $242,000 or 74.7% increase in net interest and other income resulted
from increased interest income on higher cash, cash equivalents and short-term
investments as a result of the proceeds received from the sale of the dental and
recovery products businesses in 1997.
The income tax benefit in 1997 of $2.1 million reflects recognition of
$1.7 million of deferred tax assets, primarily consisting of net operating loss
carryforwards, which had previously been fully reserved in accordance with
Statement of Financial Accounting Standards No. 109, Accounting for Income
Taxes, and tax losses of our subsidiary, Cross.
LIQUIDITY AND CAPITAL RESOURCES
At December 31, 1998, cash, cash equivalents and short-term investments
totaled $7.9 million as compared to $16.6 million at the end of 1997. The
decrease in cash, cash equivalents and short-term investments of $8.7 million
was primarily the result of the payment of $4.2 million in merger-related
expenses, restructuring charges and non-recurring charges; the repurchase of
$3.1 million of our common stock; and the redemption of $1.8 million of
convertible debentures, all during 1998. Accordingly, total working capital
decreased to $25.5 million at December 31, 1998 from $31.7 million at December
31, 1997 and the current ratio decreased to 7.3 from 7.7.
We had $7.9 million of cash and cash equivalents available at December
31, 1998 to support the continued investment in the development of our business,
including the development or acquisition of new bone biologic and spinal implant
products, and possible acquisitions of businesses. We have a $5 million
revolving line of credit which had no amount outstanding at December 31, 1998
and which expires in July 1999. We intend to negotiate an extension of the line
of credit prior to its expiration, but there can be no assurance that an
extension will be obtained.
At December 31, 1998, there were no material commitments for capital
expenditures.
We believe we currently possess sufficient resources to meet the cash
requirements of our operations for at least the next year.
IMPACT OF YEAR 2000
The Year 2000 issue is the result of computer programs being written
using two digits rather than four to define the applicable year. If not
corrected, many computer applications could fail or create erroneous results by
not recognizing "00" to mean the year 2000. We use only third party software,
and in our Annual Report on Form 10-K for the fiscal year ended December 31,
1997, we reported on our initial assessment of this software.
State of Readiness
In our initial assessment, we contacted the authors of our critical
software programs and determined that each was either already Year 2000
compliant or expected to be Year 2000 compliant by December 31, 1999. We have
identified our remaining software as well as hardware, vendors and customers
(collectively "Elements") and are currently in the process of determining those
which we consider to be mission critical. For Elements determined to be mission
critical, we will seek to obtain assurances of Year 2000 compliance. The
assurances sought will be in the form of vendor or customer certifications,
identification of alternatives, Company-administered testing efforts, or a
combination of certain assurances. We have no way of ensuring that mission
critical vendors or customers will be Year 2000 compliant, and their inability
to become compliant on a timely basis could materially impact our operations or
financial condition.
20
21
Costs to Address Our Year 2000 Issues
Through December 31, 1998, we have not incurred any direct costs
associated with Year 2000 issues. Certain costs associated with the
consolidation of operations following our merger with Cross resulted in
obtaining software/hardware that is Year 2000 compliant. While the process of
evaluating Elements is not complete, at this time, we do not believe that we
will need to replace any material non-compliant systems or hire any Year 2000
solution providers. Therefore, at this time, we estimate that future costs to
address Year 2000 issues should not be material.
Risks of Our Year 2000 Issues
We have yet to identify any mission critical Element that we expect to
not be Year 2000 compliant. In the continuing process of evaluating Elements, we
will have to rely on third party certifications of Year 2000 compliance. In the
event that mission critical Elements fail to be compliant, we could experience a
material disruption in operations, including, but not limited to: interruption
in supply of parts from vendors, inability to deliver products to customers or
to produce products on schedule, or failure of financial systems, all of which
could materially affect our business and cause a loss of customers.
Contingency Plans
We have not established a contingency plan relative to Year 2000 issues.
As our assessment continues, if it is determined that any mission critical
Elements are likely not to be Year 2000 compliant, we will develop a contingency
plan.

REPORT OF INDEPENDENT AUDITORS
Board of Directors
Interpore International, Inc.
We have audited the accompanying consolidated balance sheets of
Interpore International, Inc. as of December 31, 1998 and 1997, and the related

included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and the schedule based on our audits. We did not audit the financial
statements and schedule of Cross Medical Products, Inc., which statements
reflect total assets of $18,762,000 as of December 31, 1997, and total revenues
of $12,918,000 and $8,572,000 for the years ended December 31, 1997 and 1996,
respectively. Those statements and schedule were audited by other auditors whose
reports have been furnished to us, and our opinion, insofar as it relates to the
data included for Cross Medical Products, Inc., is based solely on the report of
the other auditors.
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 and the reports of other auditors provide a
reasonable basis for our opinion.
In our opinion, based on our audits and the reports of other auditors,
the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of Interpore International, Inc.
at December 31, 1998 and 1997, and the consolidated results of its operations

opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

Interpore International, Inc.
Notes to Consolidated Financial Statements
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
ORGANIZATION AND DESCRIPTION OF BUSINESS
Interpore International, Inc., doing business as Interpore Cross
International ("Interpore Cross") is a medical device company that operates in
one business segment: the design, manufacture and marketing of synthetic bone
and tissue products and spinal implant devices. The products are distributed in
the United States and internationally.
BASIS OF PRESENTATION
The accompanying consolidated financial statements include the accounts
of Interpore Cross and its subsidiaries after elimination of all significant
intercompany transactions. The merger of Interpore and Cross has been accounted
for as a pooling-of-interests. Accordingly, financial information for all
periods presented has been restated to include the financial information of each
company. Certain amounts have been reclassified to conform to the 1998
presentation.
DISCONTINUED OPERATIONS
In March 1997, substantially all of the assets and liabilities related
to Cross' recovery products segment were sold. The accompanying consolidated
financial statements reflect the reclassification of the recovery products
segment as discontinued operations. Income from discontinued operations has been
adjusted for the effect of the allocation of certain general corporate overhead
costs associated with continuing operations. Interest expense has been allocated
to continuing operations based upon specific identification of indebtedness to
be retained. Unless otherwise stated, the notes to the financial statements
disclose information related to continuing operations.
REVENUE RECOGNITION
Revenue from product sales is recognized at the time of shipment.
Revenue from sales of consigned inventory is recorded upon receipt of written
acknowledgement from sales agents or customers that the surgical procedure has
been completed. Provision is made currently for estimated product returns based
on historical experience and other known factors.
PER SHARE INFORMATION
In 1997, the FASB issued Statement No. 128 (SFAS 128), Earnings Per
Share, which replaced the calculation of primary and fully diluted earnings per
share with basic and diluted earnings per share. Unlike primary 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. All earnings per share amounts for all periods
have been presented to conform with the requirements of SFAS 128.
CONCENTRATIONS OF BUSINESS AND CREDIT RISK
Interpore Cross operates in markets which are subject to rapid
technological advancement and significant government regulation. The
introduction of technologically advanced products by competitors and increased
regulatory barriers could have a material impact on the future operations of
Interpore Cross.
F-7
32
In the normal course of business, Interpore Cross provides credit to
its customers. At December 31, 1998, 60% of Interpore Cross' accounts receivable
are from domestic customers, and 40% are from foreign customers. Interpore Cross
performs ongoing credit evaluations of its customers and maintains allowances
for potential credit losses which, when realized, have been within the range of
management's expectations. As of December 31, 1998, Interpore Cross had no
significant concentrations of credit risk. Sales to domestic customers were 77%,
76% and 78% of total sales in 1998, 1997 and 1996, respectively, and sales to
foreign customers were 23%, 24% and 22% of total sales in 1998, 1997 and 1996,
respectively. All sales to foreign customers for the periods presented were
denominated in United States dollars.
STOCK OPTION PLANS
During 1996, Interpore Cross adopted the disclosure-only provisions of
Statement of Financial Accounting Standards No. 123 (SFAS 123), Accounting for
Stock-Based Compensation, and, accordingly, is continuing to account for its
stock-based compensation plans under Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees and related interpretations. The
adoption of SFAS 123 had no impact on Interpore Cross' consolidated results of
operations or financial position.
ADVERTISING
Interpore Cross expenses the costs of advertising as incurred.
RESEARCH AND DEVELOPMENT
Expenditures for research and development are expensed as incurred.
SHORT-TERM INVESTMENTS
Interpore Cross invests excess cash in United States Treasury
securities and high grade corporate marketable securities. Highly liquid
investments with a maturity of three months or less at the date of purchase are
classified as cash equivalents. Short-term investments consist of highly liquid
investments with a maturity of more than three months when purchased. Pursuant
to Statement of Financial Accounting Standards No. 115, Accounting for Certain
Investments in Debt and Equity Securities, Interpore Cross' short-term
investments are classified as available-for-sale securities and are reported at
fair market value. At December 31, 1997, there were no material unrealized gains
or losses on the short-term investments.
INVENTORIES
Inventories are stated at the lower of average cost or market.
Inventories are comprised of the following (in thousands):
1998 1997

======== ========
Depreciation is provided using the straight-line method over the
following estimated useful lives:
Machinery and equipment 3 to 5 years
Furniture and fixtures 5 years
Leasehold improvements Lesser of estimated useful life or term of lease
INTANGIBLE ASSETS
Intangible assets include patents, license rights and a customer list.
The patents and license rights are amortized on a straight-line basis over their
useful lives of seventeen years. Amortization begins at the time the patents are
granted. The customer list is amortized over its estimated useful life of two
years. Management periodically evaluates the recoverability of intangible assets
based on undiscounted future cash flows. Amortization expense for the years
ended December 31, 1998, 1997 and 1996 was $75,000, $6,000 and $2,000,
respectively. Accumulated amortization of intangible assets was $84,000 and
$9,000 at December 31, 1998 and 1997, respectively.
CONSOLIDATED STATEMENTS OF CASH FLOWS
Interpore Cross paid (received refund of) income taxes of $1,053,000,
$129,000 and $(17,000) and interest of $416,000, $604,000 and $384,000 in 1998,
1997 and 1996, respectively.
IMPAIRMENT OF LONG-LIVED ASSETS
In accordance with Statement of Financial Accounting Standards No. 121,
Accounting for the Impairment of Long-Lived Assets, Interpore Cross reviews
long-lived assets and certain intangibles whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Based upon Interpore Cross' analysis, Interpore Cross believes no
impairment of the carrying value of its long-lived assets existed at December
31, 1998.
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 amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.
2. BUSINESS COMBINATION
In February 1998, Interpore International ("Interpore") entered into an
agreement to merge with Cross Medical Products, Inc. ("Cross"), a publicly
traded Ohio-based worldwide supplier of spinal implant systems used
F-9
34
to treat degenerative conditions and deformities of the spine. The merger was
approved by the stockholders of both companies on May 6, 1998 and became
effective on May 7, 1998. Shareholders of Cross received 1.275 shares of
Interpore common stock for each share of issued and outstanding Cross common
stock. Accordingly, Interpore issued 6.7 million shares of its common stock to
Cross shareholders in exchange for all of the outstanding common stock of Cross.
In addition, approximately 895,000 shares of Interpore Cross common stock were
reserved for issuance upon the exercise of assumed Cross stock options. The
merger has been accounted for as a pooling-of-interests.
During the second quarter of 1998, Interpore Cross recorded
merger-related expenses and restructuring charges of $3.0 million and $1.5
million, respectively. The merger-related expenses included legal, accounting
and administrative costs incurred in connection with the merger of Interpore and
Cross. The restructuring charges were associated with the closing of the Dublin,
Ohio facility and included severance benefits for 23 employees not remaining
with Interpore Cross, the write-off of fixed assets which were not transferred
to Interpore Cross' Irvine, California headquarters, and the accrual of
remaining lease payments for the Dublin facility. During the third and fourth
quarters of 1998, Interpore Cross recorded $474,000 of non-recurring charges
related to the relocation of assets and employees from the Dublin, Ohio facility
to the Irvine, California headquarters.
Restructuring costs and related liabilities for the year ended December
31, 1998 are summarized below (in thousands):
ACCRUED

Remaining lease payments 501 76 425
Write-off of fixed assets 229 229 --
------ ---- ----
$1,512 $803 $709
====== ==== ====
Interpore Cross expects that the remaining $709,000 accrued
restructuring costs at December 31, 1998 are adequate to cover remaining
exposures and will be paid over the next 28 months.
Selected financial information for the combining entities included in
the consolidated statements of operations for the four months ended April 30,
1998 and the two years ended December 31, 1997 and 1996 are as follows (in

3. LONG-TERM DEBT
Long-term debt at December 31, 1998 and 1997 consisted of the
following:
1998 1997
------ ------
Convertible Subordinated Debentures, due in June 2003 plus interest at
8.5%, payable semi-annually $3,152 $5,080

Obligations under capital leases 44 59
------ ------
3,196 5,219
Less current maturities 15 95
------ ------
$3,181 $5,124
====== ======
The 8.5% Convertible Subordinated Debentures (the "Debentures") due
June 1, 2003 are convertible at any time before maturity, unless previously
redeemed, into shares of Interpore Cross common stock at a conversion price of
$6.37 per share. Pursuant to the terms of the underlying indenture, upon the
merger of Interpore and Cross, Debenture holders were allowed to request
redemption until June 26, 1998 at 101% of the principal amount thereof, plus
accrued interest. Requests for redemption totaling $1.8 million were made.
Beginning July 1, 1999 and on July 1 of each succeeding year, Interpore Cross
will be obligated to redeem any Debentures tendered by June 1, 1999 or June 1 of
any succeeding year, respectively, at 100% of the principal amount thereof plus
accrued interest, subject to an annual limitation of $25,000 per holder and an
annual aggregate limitation of $262,500. During 1998, $97,000 of Debentures were
converted into 15,221 shares of Interpore Cross common stock. The fair value of
the Debentures approximates the book value at December 31, 1998 and 1997.
Other assets include $573,000 of offering costs related to issuance of
the Debentures. Amortization of offering costs of $206,000 and $83,000 for the
years ended December 31, 1998 and 1997, respectively, are included in interest
expense. Accumulated amortization was $359,000 and $129,000 as of December 31,
1998 and 1997, respectively.
During 1995, Cross obtained a loan from a split-dollar life insurance
policy in the irrevocable life trust of a significant shareholder and director
at an interest rate of 8%. This loan was paid off in 1998.
Interpore Cross has available a $5 million line of credit facility with
its primary bank. The line is secured by substantially all of the assets of
Interpore Cross, bears interest at the bank's prime rate (7.75% at December 31,
1998), and matures July 5, 1999. The facility contains certain financial
covenants with which Interpore Cross was in compliance at December 31, 1998. No
amount was outstanding under the facility at December 31, 1998.
Long-term debt matures as follows (in thousands):

4. STOCKHOLDERS' EQUITY
SERIES E CONVERTIBLE PREFERRED STOCK
The terms of the Series E Convertible Preferred Stock provide for
noncumulative dividends to be paid at the times and in the amounts paid per
share on the common stock and a liquidation preference at an amount no greater
than $7.50 per share. The Series E Convertible Preferred Stock has no redemption
rights (although Interpore Cross may redeem the stock in certain circumstances)
and is convertible into common stock at conversion ratios averaging 1.005 shares
of common stock for each share of preferred stock, subject to certain
antidilution provisions. In addition, the Series E Convertible Preferred Stock
will automatically convert into common stock at such time as the closing sale
price of Interpore Cross' common stock as reported on The Nasdaq Stock Market
has been at least $10.00 per share for at least 20 out of 30 consecutive trading
days.
COMMON STOCK
In connection with the merger, Interpore Cross was reincorporated from
California to Delaware on May 6, 1998, and the total number of common shares
authorized was increased from 20 million no par value shares to 50 million
shares with $.01 par value per share.
STOCK OPTIONS
Interpore Cross has six stock option plans that provide for the
granting of either incentive stock options or non-qualified stock options to
officers, key employees, directors and advisors. The 1995 Stock Option Plan (the
"1995 Plan") and the Stock Option Plan for Non-Employee Directors (the
"Directors Plan") are the only two plans with stock option awards available for
grant. The other four plans have either expired or have been terminated with
respect to future option grants, but have shares exercisable at December 31,
1998. Options outstanding under Interpore Cross' six stock option plans
generally vest over a four- or five-year period, and expire either six years or
ten years from the date of grant.
The number of shares reserved for issuance under the 1995 Plan
increases annually by an amount equal to 3% of the number of shares of common
stock issued and outstanding as of the close of business on December 31 of the
immediately preceding year, up to the plan maximum of 1.5 million shares. The
maximum number of shares which may be issued pursuant to options granted during
1999 is approximately 403,641.
The Directors Plan provides for a maximum of 200,000 shares to be
issued pursuant to options granted under the plan. At December 31, 1998, there
were approximately 136,500 shares available for grant under the Directors Plan.
The following is a summary of stock option activity for the periods
indicated:

The weighted average remaining contractual life of stock options
outstanding at December 31, 1998, 1997 and 1996 were approximately 5.2, 4.9 and
5.1 years, respectively.
EMPLOYEE STOCK PURCHASE PLAN
Interpore Cross has a qualified employee stock purchase plan which
allows employees to purchase shares of Interpore Cross common stock every six
months through payroll deductions. The purchase price for the shares is 85% of
the lesser of the fair market value of such shares on the first or last day of
each six-month period. The plan provides for a maximum of 100,000 shares to be
issued pursuant to the plan. As of December 31, 1998, 67,096 shares of common
stock had been issued pursuant to the plan.
STOCKHOLDER RIGHTS PLAN
Effective November 1998, Interpore Cross' Board of Directors adopted a
Stockholder Rights Plan. Every share of Interpore Cross common stock currently
issued or to be issued is accompanied by one right, and every common share
issued upon conversion of Interpore Cross preferred stock also will be
accompanied by one right. The plan provides for the rights to become exercisable
upon the earlier to occur of (i) ten days following the announcement that a
person or group of persons has acquired or obtained the right to acquire 15% or
more of Interpore Cross common stock, or (ii) ten days following the
announcement or commencement of a tender offer which would result in ownership
of 15% or more of the common stock.
If any person or group of persons acquires 15% or more of Interpore
Cross common stock, each right, once exercisable and excluding any rights
acquired by the 15% holder, will entitle its holder to purchase that number of
additional shares of Interpore Cross common stock having a market value of twice
the rights' exercise price. If Interpore Cross is involved in a merger or other
business combination involving the exchange of Interpore Cross common stock for
stock of an acquiring company at any time after the rights become exercisable,
each right will entitle its holder to purchase that number of the acquiring
company's common stock having a market value of twice the rights' exercise
price.
The rights' current exercise price is $33.00. The exercise price and
the number of shares issuable upon exercise are subject to adjustment from time
to time to prevent dilution. The rights will expire on November 17, 2007,
subject to Interpore Cross' right to extend such date, unless earlier redeemed
or exchanged by Interpore Cross or terminated. Interpore Cross is entitled to
redeem the rights at one cent per right at any time before they become
exercisable.
COMMON STOCK REPURCHASE PROGRAM
In November 1998, Interpore Cross' Board of Directors approved a plan
to repurchase up to 4.0 million shares of Interpore Cross common stock. Through
December 31, 1998, Interpore Cross repurchased 605,000 shares
F-13
38
at a cost of approximately $3.1 million under this program. The Board of
Directors has determined that no further stock repurchases will occur pursuant
to this approval.
ACCOUNTING FOR STOCK-BASED COMPENSATION
Interpore Cross applies Accounting Principles Board Opinion No. 25 (APB
25), Accounting for Stock Issued to Employees, and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under Statement of Financial
Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based
Compensation, requires use of option valuation models that were not developed
for use in valuing employee stock options. Under APB 25, because the exercise
price of Interpore Cross' employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.
Pro forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if Interpore Cross had
accounted for employee stock options granted on or after January 1, 1995 under
the fair value method of SFAS 123. The fair value for these options was
estimated at the date of grant using the Black-Scholes option pricing model with
the following weighted average assumptions: a risk-free interest rate of 6% in
1998 and 6% or 7% in 1997 and 1996, a volatility factor of the expected market
price of Interpore Cross common stock of .75 in 1998 and .51 or .57 in 1997 and
1996, a weighted-average expected life of the options of six years in 1998 and
five years in 1997 and 1996, and no dividend yield.
For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting periods. Interpore
Cross' pro forma information, which reflects the charges related to options
issued in 1998, 1997 and 1996 and may not be indicative of such charges in
future periods, is as follows:
1998 1997 1996
------- ------ ------
Pro forma net income (loss) (in thousands) $(3,138) $3,559 $1,421
Pro forma basic net income (loss) per share $ (.23) $ .26 $ .11
Pro forma diluted net income (loss) per share $ (.23) $ .25 $ .10
5. INCOME TAXES
Interpore Cross uses the liability method of accounting for income
taxes as set forth in Statement of Financial Accounting Standards No. 109,
Accounting for Income Taxes. Under this method, deferred taxes are determined
based on the difference between the financial statement and tax bases of assets
and liabilities using enacted tax rates in effect in the years in which the
differences are expected to reverse. Deferred tax assets are recognized and
measured based on the likelihood of realization of the related tax benefit in
the future.
A reconciliation of the income tax provision (benefit) using the
federal statutory rate to the book provision for income taxes follows (in
thousands):

At December 31, 1998, Interpore Cross has unused net operating loss
carryforwards of approximately $8.6 million for federal income tax purposes
which expire beginning in 2001. Interpore Cross also has research and
development tax credit and alternative minimum tax credit carryforwards of
approximately $370,000 for federal tax purposes and $22,000 for California tax
purposes. The research and development tax credit carryforward began to expire
in 1998. Prior to 1995, a valuation allowance was recorded to entirely offset
the tax benefits of the federal carryforwards. In 1998, 1997 and 1996, the
valuation allowance was reduced to recognize the future tax benefits which
management believes are more likely than not to be realized.
The Tax Reform Act of 1986 includes provisions which significantly
limit the potential use of net operating losses and tax credit carryforwards in
situations where there is a change in ownership, as defined, of more than 50%
during a cumulative three-year period. Accordingly, if a change in ownership
occurs, the ultimate benefit realized from these carryforwards may be
significantly reduced in total, and the amount that may be utilized in any given
year may be significantly limited. California has enacted similar legislation.
Interpore Cross has had stock issuances during the past three years and as a
result of the merger with Cross, a greater than 50% change in ownership occurred
during the year ended December 31, 1998. Accordingly, the use of these
carryforwards will be limited to approximately $2.3 million per year.
In addition to the net operating losses discussed above, Interpore
Cross has net operating loss carryforwards and research and development tax
credit carryforwards at December 31, 1998 of approximately $6.6 million and
$55,000, respectively, for federal income tax purposes resulting from the
acquisition of Interpore Orthopaedics, Inc. ("Orthopaedics"). As a result of the
acquisition, Orthopaedics experienced a more than 50% ownership change.
Accordingly, under the provisions of the 1986 Tax Reform Act, the use of
Orthopaedics' net operating loss carryforwards is limited to approximately
$300,000 per year. These carryforwards expire beginning in the year 2001. As a
result of the annual limitation, it is estimated that a maximum of $2.9 million
in net operating loss carryforwards will be available for use prior to
expiration. The ultimate realization of the benefits of these loss carryforwards
is dependent on future profitable operations of Orthopaedics.

Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. The components
of the net deferred tax asset at December 31, 1998 and 1997 consist of the
following (in thousands):
1998 1997
-------- --------
Interpore net operating loss carryforwards $ 2,943 $ 2,940

6. COMMITMENTS AND CONTINGENCIES
LICENSE AGREEMENTS
Interpore Cross has agreements with its Synergy System Advisors under
which it pays royalties ranging from 6.5% to 8% of net revenues generated from
the sale of certain products within the Synergy Spinal Implant System.
LITIGATION
Cross and a number of other spinal implant manufacturers were named as
defendants in various products liability lawsuits alleging injuries from spinal
implants supplied by Cross and others. All such lawsuits were consolidated for
pretrial proceedings in the Federal District Court for the Eastern District of
Pennsylvania and, on February 22, 1995, class certification was denied. This
forced the plaintiffs to file individual, rather than class action suits. Over
1,100 such suits were initially filed; however, Cross was dismissed from these
lawsuits for failure of the plaintiffs to state a viable claim. A large number
of plaintiffs filed new lawsuits against Cross and others alleging, in addition
to damages from spinal implants, a conspiracy among manufacturers, physicians
and other spinal implant industry members to defraud the public and market
products without the proper regulatory approvals. Cross was named as a
defendant, among others, in approximately 797 such lawsuits. Interpore Cross
cannot estimate precisely the number of such lawsuits that may eventually be
filed or in how many lawsuits Cross will be named as a defendant. In
approximately 235 of these cases, which involved products manufactured by
Acromed, another spinal implant manufacturer, Cross has been dismissed as a
defendant. Cross has also been dismissed as a defendant from approximately 79
additional cases. Of the remaining conspiracy cases, none involve products
manufactured by Cross.
The conspiracy cases remain coordinated for pretrial purposes only.
Plaintiffs in the conspiracy cases typically seek relief in the form of monetary
damages, often in unspecified amounts. While the aggregate monetary damages
eventually sought in all of such individual actions are substantial and exceed
the limits of Cross' products liability insurance policies, Interpore Cross
believes that Cross has affirmative defenses, and that these individual lawsuits
are otherwise without merit.
The lawsuits are being defended by Cross' insurance carrier, in some
cases under a reservation of rights. Cross maintains claims made products
liability insurance policies with $5 million of coverage both per occurrence and
in the aggregate. Interpore Cross and Cross believe that they have adequate
insurance for their businesses, however, there can be no assurance that the $5
million per policy year limit of coverage will be sufficient to cover
F-16
41
the cost of defending all lawsuits or the payment of any amounts that may be
paid in satisfaction of any settlements or judgments. Further, there can be no
assurance that Cross will continue to be able to obtain sufficient amounts of
products liability insurance coverage at commercially reasonable premiums.
Future operating results could be materially adversely affected by the cost of
defending litigation or the formal resolution of pending cases or future claims,
whether or not such defense costs, cases or claims are covered by insurance.
Aside from the conspiracy litigation, the nature of Interpore Cross'
business subjects it to products liability and various other legal proceedings
from time to time. In the opinion of management, the amount of ultimate
liability with respect to any known proceedings or claims, excluding the
conspiracy litigation, will not materially affect the financial position or
results of operations of Interpore Cross.
7. LEASE COMMITMENTS
Future minimum rentals under noncancelable operating leases for
manufacturing and office facilities and equipment at December 31, 1998 are as
follows (in thousands):
1999 $ 736
2000 738
2001 602
2002 484
Thereafter 39
-------
$ 2,599
=======
Rent expense was $706,000, $792,000 and $777,000 in 1998, 1997 and
1996, respectively.
The lease for Interpore Cross' principal office and manufacturing
facility, which expires January 31, 2003, provides a right to extend the lease
for an additional five years at the fair market lease rate of the facility on
the extension date, but not less than the rate paid by Interpore Cross during
the month immediately preceding the commencement of the extension period.
8. SALE OF ASSETS
In April 1997, Interpore entered into a definitive agreement for the
sale of its dental implant business. In May 1997, the sale was completed, and
Interpore received an initial cash payment of $1.5 million. A deferred cash
payment of $749,000 was received in March 1998. The transaction, including
associated costs, resulted in a net charge of $617,000 in the second quarter of
1997.
9. SALE OF RECOVERY PRODUCTS SEGMENT
On March 12, 1997, Cross entered into an agreement to sell its recovery
products segment for approximately $8.2 million in cash and the assumption of
approximately $5.0 million of debt and other liabilities. The buyer also
acquired 30,000 shares of Cross' common stock for $242,000. Cross recognized a
gain of $2.2 million, net of related income taxes of $1.4 million. Revenues for
the recovery products segment were $2.5 million through the date of disposal for
the year ended December 31, 1997 and $9.9 million for the year ended December
31, 1996.

(1) In May 1998, Interpore and Cross merged and subsequently closed the
Dublin, Ohio facility. Merger-related expenses and restructuring charges
associated with the merger totaling $4.5 million were recorded in the
second quarter of 1998. Non-recurring charges related to the
consolidation of operations to the Irvine, California facility amounting
to $381,000 and $93,000 were recorded in the third and fourth quarters
of 1998, respectively.
(2) Interpore Cross' dental implant business was sold in May 1997. This
transaction, including associated costs, resulted in a net charge to
operating expenses of $617,000 in 1997. Net sales of dental implants
were approximately $1.4 million and $262,000 in the first and second
quarters of 1997.
(3) In 1997, Interpore Cross recognized an inventory valuation adjustment of
$925,000 for obsolete and slow moving inventory related to its spinal
implant system.
(4) A $1.7 million credit was recorded in the fourth quarter of 1997 to
reflect the reduction in the valuation allowance against deferred tax
assets.
