Company Overview

     Osteotech,  Inc.  ("Osteotech")  provides  services and products  primarily
focused in the repair and healing of the musculoskeletal  system. These products
and services are marketed to the orthopaedic, neurological,  oral/maxillofacial,
dental and general surgery markets in the United States and Europe. Based on our
knowledge  of the  allograft  bone tissue  industry,  we believe that we are the
world's largest processor and developer of human bone and bone connective tissue
("allograft  bone  tissue")  products.  The allograft  bone tissue  processed by
Osteotech is procured by independent tissue banks primarily through the donation
of tissue from deceased  human donors and is used for  transplantation.  We have
two primary operating segments:

     o    the   Grafton(R)   Demineralized   Bone  Matrix  (DBM)   segment  (the
          "Grafton(R) DBM segment"); and

     o    the Base Allograft Bone Tissue segment (the "Base Tissue segment").

     In the Grafton(R) DBM segment we process and market Grafton(R) DBM which is
distributed  by our  clients.  Grafton(R)  DBM is  processed  using our advanced
proprietary  demineralization  process.  When  applied to  cortical  bone,  this
process yields  allograft bone tissue which has  osteoinductive  (the process by
which bone is induced  to grow) and  osteoconductive  (the  matrix  provided  by
allograft  bone tissue into which the host bone can grow)  capabilities  greater
than currently available forms of mineralized allograft bone tissue.

     In the Base Tissue segment we process primarily mineralized  weight-bearing
allograft  bone  tissue  which is  generally  marketed  and  distributed  by our
clients.  We recently  introduced the bio-d(TM) threaded cortical bone dowel for
spinal fusion which is processed in the Base Tissue segment.  This bone dowel is
distributed by our clients,  but unlike other tissue  processed in this segment,
we market the bio-d(TM) threaded cortical bone dowel.

                                        1

<PAGE>


     We have  leveraged our expertise in  musculoskeletal  tissue  technology to
develop  innovative  processes and proprietary  products that are widely used by
orthopaedic,  spinal,  neurological and  oral/maxillofacial  surgeons for spinal
fusion  procedures,  to repair and replace bone loss caused by trauma or certain
disease states, to augment  prosthetic implant procedures and to replace damaged
ligaments and tendons.

     In addition to our  Grafton(R)  DBM  segment  and Base Tissue  segment,  we
provide  ceramic and titanium  plasma spray coating  services to orthopaedic and
dental  implant   manufacturers   through   operations  based  in  Leiden,   The
Netherlands.  We also market and  distribute  non-allograft  bone tissue  spinal
implant products.

     We estimate  that the total bone graft market in the U.S. for 1998 was $487
million. This market includes allograft bone tissue procedures,  synthetic graft
substitutes and autograft bone tissue  procedures  (transplant  tissue harvested
from the patient).  We estimate that the  allograft  bone tissue  portion of the
total bone graft  market in the U.S.  grew 16% in 1998,  to  approximately  $168
million.  The allograft bone tissue market is growing at a substantially  faster
rate  than the  general  bone  grafting  market,  as  allograft  bone  tissue is
increasingly  becoming an accepted surgical alternative to autograft procedures.
Autograft bone tissue often requires a second surgical procedure to harvest bone
from the  patient's  own body and,  therefore,  exposes the patient to increased
risk  associated with blood loss,  infection and chronic pain.  Increased use of
allograft bone tissue is expected to continue as physicians become  increasingly
educated  about the benefits of allograft  bone tissue and concerns over disease
transmission  are  diminished.  Moreover,  allograft bone tissue is increasingly
preferred for use in elderly  patients,  who often lack  sufficient  harvestable
bone.

     Based upon our knowledge of the allograft bone tissue industry, we estimate
that we process  between 40% and 50% of the allograft  bone tissue donors in the
U.S.  We  believe  that  our  strong  market  position  is  attributable  to our
proprietary  product line, our clients'  national donor recovery  programs,  our
large national sales and marketing  organization and the substantial  investment
we have made in  processing  technology to ensure  stringent  standards and high
quality  control  which,  combined with  extensive  donor  screening and testing
performed by our clients,  has virtually  eliminated the risk of transmission of
infectious agents.

     Osteotech  processes  allograft  bone  tissue  for its  clients  which  pay
Osteotech  fees. In the Grafton(R) DBM segment fees are paid on a per unit basis
for the  Grafton(R)  DBM products  which we process.  In the Base Tissue segment
fees are paid on a per donor basis, except in the case of the bio-d(TM) threaded
cortical bone dowel, for which fees are paid on a per unit basis.

     We process  allograft  bone  tissue  pursuant to  contracts  with two large
not-for-profit  organizations,  American Red Cross Tissue  Services  ("ARC") and
Musculoskeletal  Transplant  Foundation ("MTF"). ARC and MTF are responsible for
donor  procurement and distribution of processed bone tissue.  Our contract with
ARC expires in December,  2006 and our contract with MTF expires in March, 2002.
These  contracts  solidified  key donor  availability  for  Osteotech  processed
allograft bone tissue.

     Osteotech  markets the  proprietary  products in the Grafton(R) DBM segment
and the  bio-d(TM)  threaded  cortical  bone  dowel in the Base  Tissue  segment
through independent agents and direct field sales personnel.  The other products
processed  in our Base Tissue  segment are  marketed  generally  by our clients,
primarily using direct field personnel. Our products are gaining wide acceptance
among  surgeons  in a broad  spectrum  of  orthopaedic  procedures  due to their
flexibility, unique handling characteristics and ability to enhance bone growth.

     Revenues in our Grafton(R) DBM segment increased 47% to $39,128,000 in 1998
and revenues in our Base Tissue segment increased 20% to $17,323,000 in 1998. We
expect that both our Grafton(R)  DBM and Base Tissue  segments will be important
contributors to the growth of our consolidated  revenues and profits in 1999, as
processed allograft bone tissue forms continue to gain increased acceptance.

Strategy

     Overview

     o    We intend to use our position as the leader in  allograft  bone tissue
          processing  to  continue  to educate  the  medical  community  and the
          general public concerning the benefits of allograft bone tissue.

     o    We intend to use our strong research and development  capabilities and
          expertise in musculoskeletal science to:

          *    enhance the performance of our existing allograft bone tissues;

          *    expand  the  safety  claims of these  tissues  using  proprietary
               processes; and

          *    continue to introduce new tissue forms with enhanced  performance
               profiles.

     Grafton(R) DBM Segment

     In the near term,  we will  continue to focus on marketing  Grafton(R)  DBM
through our  national  agent  network and medical  education  programs.  We will
support  these  programs  through  prospective  clinical and outcome  studies to
further  validate the  performance,  utility and safety of  Osteotech  processed
tissue.


                                        3

<PAGE>


     We expect to continue expansion of sales of Grafton(R) DBM through:

     o    surgeon identified new procedures;

     o    surgeon oriented medical education programs;

     o    in-depth sales agent training programs;

     o    published clinical support;

     o    product line extensions;

     o    global expansion with an initial European focus; and

     o    the pursuit of opportunities created by the expected high growth in
          spinal, trauma and total joint revisions.

     Base Tissue Segment

     We expect to achieve continued growth in the Base Tissue segment through:

     o    the continued  market launch (which began in December 1998) throughout
          1999  of the  bio-d(TM)  threaded  cortical  bone  dowel  and  related
          instrumentation  as an alternative to metal threaded  fusion cages and
          pedicle screw fixation for certain spinal procedures;

     o    introduction of new packaging and a new validated  viral  inactivation
          claim;

     o    global  expansion  of base  allograft  bone  tissue  grafts and tissue
          processing business in selected countries, initially in Europe;

     o    development  of  proprietary  tissue  processing   technology  through
          internal research; and

     o    development  of new  allograft  bone  tissue  products  with  enhanced
          performance profiles.

     Biomaterials and Non-Allograft Bone Tissue Spinal Implant Products

     Our  strategy in our  biomaterials  and  non-allograft  bone tissue  spinal
implant product business lines is to:

     o    continue focusing our European non-allograft bone tissue operations to
          capture  available  opportunities  for ceramic  coating  services  and
          powder manufacture;

     o    capitalize on high-growth  opportunities  in the U.S.  spinal products
          market with innovative non-allograft bone tissue products; and

     o    enter into  agreements  with other  health care  product  companies to
          utilize our technology and expertise in the non-allograft  bone tissue
          area  for the  development  and  manufacture  of  proprietary  product
          components.


                                        4

     Spinal Strategy

     Our strategy  consists of two primary  components  involving our Grafton(R)
DBM and Base Tissue  segments and our  non-allograft  bone tissue spinal implant
product line of business:

     o    continue the U.S.  roll-out (which began in December 1998)  throughout
          1999 of the Segmented  Spinal  Correction  System  (SSCS(TM)),  a load
          sharing,  low profile  posterior  lumbar and  thoracic  rod and hinged
          screw system; and

     o    market   our   bio-d(TM)   threaded   cortical   bone  dowel  and  our
          non-allograft  bone tissue spinal implant  products  together with our
          Grafton(R)  DBM  through  our  extensive  sales  agency  network.  Our
          intention is to educate surgeons to use Grafton(R) DBM, our  bio-d(TM)
          threaded cortical bone dowel and our SSCS(TM) system,  either alone or
          in conjunction  with each other.  Spinal implant products which we add
          to our product mix in the future will be included in this strategy.

Business Summary

     Bone  and  related  tissue  transplants  are  often  necessary  to  correct
deformities   and  repair  and   reconstruct   defects   caused  by   congenital
malformations,  trauma,  infections,  cancer and other disease  conditions.  For
certain  procedures,  autograft bone tissue can be acquired from another part of
the patient's skeleton by an additional operative procedure.  For a large number
of  procedures  for which  autograft  bone tissue is not feasible or  desirable,
allograft  bone tissue  previously  obtained from  cadavers or surgical  patient
donors  can be  utilized.  Allograft  bone  tissue is  procured  primarily  from
cadavers  by a network of organ  procurement  organizations  and/or  directly by
tissue banks.

     Osteotech  processes  allograft  bone  tissue  for its  clients in both its
Grafton(R)  DBM and Base Tissue  segments.  Once  processed,  the allograft bone
tissue is returned to these  clients for  distribution  to surgeons  and medical
institutions. The surgeons and medical institutions pay the fees established and
charged by our clients.  The surgeons  and medical  institutions  in turn charge
their patients for the various aspects of transplant  surgery performed by them,
including  standard  charges  established by the surgeon or institution for each
unit of processed  allograft  bone tissue used.  The cost to the patient for the
processed  allograft bone tissue is generally  reimbursable by medical insurance
carriers as part of the overall cost of the procedure.

     In both our Grafton(R) DBM and Base Tissue segments,  our processing yields
a wide array of  freeze-dried,  frozen and  demineralized  allograft bone tissue
that is used by  orthopaedic,  neurological,  plastic,  dental,  periodontal and
oral/maxillofacial surgeons for:

     o    spinal fusion procedures;

     o    repair  and  replacement  of bone loss  caused  by  trauma or  certain
          disease states;

     o    augmentation of prosthetic implant procedures; and


                                        5

<PAGE>


     o    replacement of damaged ligaments and tendons.

     We believe our processing methods,  our clients' tissue recovery techniques
and the multiple screening and testing procedures employed,  virtually eliminate
the risk of transmission of infectious agents.

     In our  Grafton(R)  DBM  segment,  we have a validated  viral  inactivation
process for our demineralized  bone tissue.  Studies completed by an independent
testing laboratory  specializing in viral inactivation studies demonstrated that
this proprietary demineralization process can virtually inactivate and eliminate
viruses such as HIV, hepatitis B, hepatitis C, cytomeglia and polio.

     In our Base  Tissue  segment,  we expect to begin to  implement  additional
processing technologies that, once fully implemented during 1999, will enable us
to  expand   our  viral   inactivation   claims  to  include   the   mineralized
weight-bearing allograft bone tissue processed in this segment.

     We believe that allograft bone tissue transplantation is one of the fastest
growing  areas of  transplant  medicine.  We  estimate  that in 1998  there were
approximately  494,100 grafting  procedures in the U.S. for which allograft bone
tissue could have been utilized,  representing an estimated  available allograft
bone tissue market of approximately $487 million. We estimate that the allograft
bone tissue portion of the total bone graft market in the U.S.  increased 16% in
1998 to $168 million.  Industry data indicates that the musculoskeletal surgical
market is  growing.  We  believe  this will  expand  the  potential  market  for
allograft bone tissue in both our  Grafton(R) DBM and our Base Tissue  segments,
due to a number of factors, including:

     o    increasing  frequency of surgical  procedures  that  incorporate  bone
          grafting techniques;

     o    the desire by surgeons  to avoid the  additional  procedure  needed to
          acquire  autograft bone tissue,  which often increases  operating time
          and risks such as excessive blood loss, infection and chronic pain;

     o    a reduction in the possibility of  transmission  of infectious  agents
          and  toxicity  because of improved  allograft  bone tissue  processing
          techniques and donor screening;

     o    increased  awareness by, and training of, the medical  community  with
          respect to the use of allograft bone tissue;

     o    an increasing number of musculoskeletal  procedures which require more
          bone tissue than can be obtained through autograft procedures;

     o    an increase  in the number of patients  who do not possess the quality
          of bone tissue  required for  autograft  procedures as a result of the
          general aging of the population; and


                                        6

<PAGE>


     o    an  increase  in the  availability  of  allograft  bone  tissue due to
          improved  recovery and  processing  techniques and an increase in bone
          tissue donations.

     Allograft  bone tissue is employed  in surgical  procedures  because of its
biologic and biomechanical  properties.  Bone from various locations in the body
can be processed to yield either dense cortical bone,  porous cancellous bone or
units comprised of both cortical and cancellous  bone.  Cortical bone, the thick
outer portion of bone, provides  biomechanical strength which allows the bone to
be weight-bearing,  and therefore,  is commonly used in surgery in the spine and
to the extremities and in other procedures requiring strong transplant material.
Cancellous  bone, the spongy portion of bone tissue,  is preferable for surgical
procedures,  or aspects thereof, in which rapid penetration of new bone into the
pores of the  transplant (a process known as  osteoconduction)  is desirable but
where weight-bearing  strength is not paramount.  Therefore,  cancellous bone is
often  used to fill  smaller  areas of bone loss and to augment  more  extensive
reconstructive  procedures including knee and hip replacements.  Most procedures
using  allograft  bone tissue,  however,  employ a  combination  of cortical and
cancellous bone in a variety of forms, shapes and sizes.

Allograft Bone Tissue Processing

     Base Tissue Segment

     Unlike  organs  which  require  transplantation  within  hours of recovery,
allograft bone tissue  generally goes through a processing  phase in which it is
cleaned,  cut into different sizes and forms for specific  surgical  procedures,
preserved,  packaged  and  labeled.  Osteotech  processes  its  clients'  tissue
utilizing technology it has developed which yields a wide array of freeze-dried,
frozen,  demineralized  bone and  connective  tissue  products.  Frozen  tissues
include  whole bones and major  sections  thereof,  bone  segments,  tendons and
ligaments.  Freeze-dried  bone tissues include various wedges,  strips,  struts,
dowels, cancellous cortical chips, blocks, strips and ribs.

     The  suitability  of an  allograft  bone tissue is partly  dependent on the
methods and conditions used in the processing of the tissue. Processing includes
the removal of certain  portions of the allograft  bone tissue in a manner which
enables the tissue to maintain as much of the native biological  characteristics
relating to the use of such tissue in bone grafting  procedures as possible.  To
provide suitable  allografts,  Osteotech has developed  techniques that minimize
the use of chemicals and procedures  that might render the allograft bone tissue
less  suitable  for use as a  graft.  We  process  allograft  bone  tissue  in a
microbially-controlled environment, substantially cleaner than that of a typical
hospital  operating  room,  created  through the use of advanced air filtration,
water   distillation   and  mineral  control  systems  and  other  "clean  room"
techniques.  We believe that our use of such clean room techniques, a controlled
environment, in-line disinfection and other technologies preserve the properties
of the  tissues  that make them  suitable  as grafts  and  address  the  medical
community's  and the general  public's  perceptions  and concerns  regarding the
possible  transmission of infectious disease and toxicity.  Once processed using
Osteotech's  current methods,  freeze-dried bone tissues may be stored for up to
three  years and frozen bone  tissues may be stored for up to five years  before
they must be used or discarded.

     In December, 1998 we began a region-by-region roll-out of our new bio-d(TM)
threaded  cortical  bone dowel for spinal  fusion.  We expect the roll-out to be
completed by the end of 1999.  The  bio-d(TM)  threaded  cortical bone dowel has
been tested and shown to withstand  loads  comparable  to those  reported in the
lumbar spine, and its inherent natural properties will permit  incorporation and
remodeling.  Additionally,  the hollowed center of this bone dowel can be packed
with Grafton(R) DBM.  Therefore,  the dowel will provide  structural support and
with Grafton(R) DBM added,  will also aid in the fusion process by inducing bone
growth.

     Grafton(R) DBM Segment

     In addition  to the  proprietary  procedures  which are  particular  to the
processing of Grafton(R) DBM, the technologies used in processing allograft bone
tissue in the Base Tissue segment are also used in processing Grafton(R) DBM.

     Osteotech has developed an advanced  proprietary  demineralization  process
for cortical bone which yields Grafton(R) DBM -- a form of allograft bone tissue
which can be used to aid in the  formation of new bone through the  processes of
osteoconduction and osteoinduction.  Osteoconduction is the process of providing
the matrix into which bone will grow and  osteoinduction is the process by which
bone is induced to grow. Cortical bone is believed to be the principal reservoir
for various factors which are instrumental in  osteoinduction.  These biological
properties of cortical bone, however,  are inhibited by the bone's structure and
various minerals,  lipids and other substances  comprising the bone. Our process
removes these inhibiting factors.

     In  our  Grafton(R)  DBM  segment  we  currently  process  three  forms  of
Grafton(R) DBM:

     o    Grafton(R)  DBM  Gel -- a  gel-like  substance  with  unique  handling
          characteristics  which are useful in performing bone graft  procedures
          as part of spinal fusions,  joint  replacements and repairs of osseous
          defects;

     o    Grafton(R)  DBM  Putty -- a  moldable  putty-like  graft of  entangled
          fibers of  demineralized  bone,  which is mixed easily with marrow and
          other grafts,  minimizes  migration,  can be molded easily and retains
          its shape even in larger defects; and

     o    Grafton(R)   DBM  Flex  --  a  flexible   "pressed   fiber"   form  of
          demineralized  bone processed by utilizing a pressed fiber  technique,
          providing  surgeons a pliable  form of bone graft.  It is available in
          square or strip forms,  conforms to the body's natural anatomy and can
          be easily cut for precise adaptation to host bone.

     We expect that wider  distribution  and deeper  market  penetration  by the
three forms of  Grafton(R)  DBM utilizing  our national  network of  independent
agents in combination with our direct  marketing  force,  will drive the further
growth in the use of Grafton(R)  DBM processed  allograft  bone tissue.  Through
December  31,  1998,  Grafton(R)  DBM forms had been  utilized  in over  240,000
procedures.

Expansion of Allograft Bone Tissue Business in Europe

     On June 25,  1998,  we  acquired  a 5%  interest  in OST  Developpement  SA
("OST"),  which is located in Clermont-Ferrand,  France and, on January 25, 1999
(effective January 1, 1999), we acquired an additional 85% interest in OST. OST,
which  primarily  processes  and  manufactures  products  from bovine tissue for
orthopaedic  and dental use, was  originally  founded to address the shortage of
safe and  effective  human  allograft  bone tissue in France and  certain  other
countries  outside the United  States.  OST  utilizes a  proprietary  processing
system,  which includes validated viral inactivation steps, to produce LUBBOC(R)
bovine bone grafts for orthopaedic surgical procedure applications and LADDEC(R)
bovine bone grafts for dental  surgical  procedure  applications.  Each of these
biocompatible  bone graft  materials  has  received  a  European  CE Mark and is
produced in an ISO certified plant.

     It is our strategy to utilize OST's advanced processing systems and skilled
staff as a base of operations to expand  Osteotech's human allograft bone tissue
business in Europe.  We expect to first  establish a strong  market  position in
France  and use  that as a base for  expansion  into the  other  major  European
markets. OST is currently adapting its proprietary  processing  technology to an
automated,  cost  efficient  system it is developing for the processing of human
allograft  bone tissue.  OST will  initially  use this system in our Base Tissue
segment to process human femoral heads recovered during hip replacement  surgery
for  distribution in France.  At the same time, OST will continue to process and
distribute its LUBBOC(R) and LADDEC(R) bovine bone tissue grafts.

     In the short term, we will expand the range of human  allograft bone tissue
forms  available  to  French  surgeons  by  supplying  Grafton(R)  DBM and other
allograft  bone tissue forms  processed  by  Osteotech  in the U.S.  through the
OsteoBanque  D'Auvergne tissue bank, with which OST has a long-term agreement to
provide tissue processing, logistical support and distribution services.

     Concurrently,  in connection with  OsteoBanque  D'Auvergne and other tissue
banks, we plan to help establish a cadaveric  donor tissue  recovery  network in
medical centers  throughout France and other European countries in order to meet
a growing European demand for allograft bone tissue.  Beginning with France,  we
plan to  penetrate  the  European  market on a  country-by-country  basis,  with
Germany  being the next  major  expansion  opportunity.  We have filed a product
master file in Germany to obtain approval to begin marketing and distribution of
Grafton(R) DBM and other forms of allograft bone tissue.  We expect to work with
other European tissue bank organizations to distribute these tissues in Germany.

     The   advantages  of  locating  our  European   operations  in  France  are
significant.  The  French  market is one of the  larger  and more  sophisticated
European markets for bone grafts.  Also,  French laws and regulations  governing
tissue  banking are well defined and the most advanced of all the major European
countries. Although tissue banking operations in France are generally restricted
to non-profit  public health  organizations  approved by the government,  French
regulations also provide for governmental  approval of for-profit  organizations
as tissue  banks if these  organizations  are able to provide  haute  technicite
(high  technology)  unavailable  in  the  non-profit  sector.  We  believe  that
Osteotech's tissue processing technology meets this

                                        9

<PAGE>


requirement  and that we will be able to operate  independently  as an  approved
tissue  bank  in  addition  to  providing  contract  processing,  marketing  and
management services to non-profit tissue banks.

Other

     Ceramic and Titanium Plasma Spray Coating Services and Products

     We are providing  ceramic  hydroxyapatite  ("HA") and titanium plasma spray
coating  services to  orthopaedic  and dental implant  companies in Europe.  The
primary advantage of coating  orthopaedic and dental prosthetic  devices is that
it enables bone to grow onto the implanted  device.  This enhances the stability
of the device,  which, in turn,  lowers the amount of bone loss and reduces pain
caused by micro motion.  We manufacture the HA powder which we use in our plasma
spray coating  operations  from raw materials  which are readily  available from
several sources.  Osteotech also supplies HA powder to various companies for use
in their in-house plasma spray coating operations.  Additionally,  we produce HA
products  which are used to replace  middle ear bones and for the repair of bone
defects in dental applications.

     Non-Allograft Bone Tissue Spinal Implants and Instruments

     In the U.S.  Osteotech  markets  implants  and  instrumentation  for spinal
surgery  through an exclusive  distribution  agreement  with Heinrich C. Ulrich,
K.G. ("Ulrich"). Osteotech markets Ulrich's Zielke VDS System, an implant system
used by  orthopaedic,  spinal and  neurological  surgeons  worldwide  - often in
combination  with allograft bone tissue grafts - for the anterior  correction of
spinal deformities caused by disease, trauma and degeneration. We also market an
extensive  line of more than 250 high quality,  specialty  surgical  instruments
manufactured by Ulrich.

     Osteotech  plans to continue  expanding its line of spinal implant  devices
and  instrumentation.  One of Ulrich's  spinal fixation  systems,  the SSCS(TM),
features a  proprietary  hinged  screw  design that allows for load  sharing and
provides improved results in spinal fusion procedures. The product is being sold
in Germany,  the U.K., and South Africa.  The SSCS(TM)  system  received  510(k)
clearance in the U.S. in June,  1997. We introduced the SSCS(TM)  system to U.S.
preceptors (a limited  number of  well-respected  spinal  surgeons) for clinical
evaluation  during  the second  half of 1998 and  initiated  a  region-by-region
product roll-out in the U.S. beginning in December,  1998. We expect to complete
the roll-out and have the SSCS(TM) system available to all U.S.  surgeons by the
end of 1999.

Quality Assurance

     We have stringent quality  assurance  programs in place covering all of our
lines of business,  including our Grafton(R) DBM and Base Tissue  segments,  our
HA-titanium  plasma spray coating services,  and our  non-allograft  bone tissue
spinal  implants and  instruments.  Our facility in Leiden,  The Netherlands has
received  International  Standardization  Organization ("ISO") certification for
its quality systems used in the development and manufacture of ceramic  products
and ceramic and titanium spray coatings.

     In both the Grafton(R) DBM and Base Tissue segments  Osteotech's  allograft
bone tissue quality  assurance  program commences with the recovery of allograft
bone tissue which is procured  under strict  aseptic  conditions.  The tissue is
recovered primarily in hospitals and, to a lesser extent,  coroners'  facilities
which have been prepared for recovery.  Recovered  allograft bone tissue is also
required to be sterilely wrapped and shipped in special containers. Upon receipt
of this  tissue,  a  quarantine  period  is  imposed  to  permit  serologic  and
microbiologic  testing prior to release of allograft bone tissue for processing.
Upon  satisfactory  completion  of all  testing,  the  allograft  bone tissue is
processed in a  microbially-controlled  environment.  Under constant monitoring,
the allograft  bone tissue is cleaned,  soaked in  antibiotics  and then cut and
shaped in  accordance  with  client  specifications.  Before  being  released to
clients,   all  processed   bone  tissue  is  inspected  and  again  tested  for
microbiological contaminants by our quality assurance team.

     We believe that the serologic  screening of donors, the extensive screening
of donor  profiles  and  medical  histories  performed  by our  clients  and our
processing  technologies  virtually  eliminate the likelihood of the presence of
infectious agents,  including HIV and hepatitis viruses,  in Osteotech processed
allograft bone tissue.  Studies completed by an independent  testing  laboratory
specializing in viral  inactivation  studies  demonstrated  that our proprietary
demineralization  process  used in our  Grafton(R)  DBM  segment  can  virtually
inactivate  and  eliminate  viruses  such  as HIV,  hepatitis  B,  hepatitis  C,
cytomeglia and polio.

     To our  knowledge,  none of the  approximately  1.75  million  transplanted
grafts we have  processed in our  Grafton(R)  DBM and Base Tissue  segments have
resulted in a confirmed transmission of infectious diseases.  This record is due
to the rigorous  donor  screening  and tissue  recovery  techniques  used by our
clients, extensive donor testing, as well as our demanding quality assurance and
processing protocols.  In addition to the proprietary  demineralization  process
used in our Grafton(R) DBM segment,  we expect to begin to implement  additional
processing  technologies  that once fully  implemented in 1999 will enable us to
expand our viral  inactivation  claims to include virtually all of the allograft
bone  tissue  we  process  in  our  Base  Tissue  segment.   These  proprietary,
tissue-specific  technologies are expected to further enhance graft safety while
maintaining the tissue's biologic and physical properties.

Clients

     Osteotech is the exclusive processor of allograft bone tissue for two large
clients.  In the Base  Tissue  segment,  with  the  exception  of the  bio-d(TM)
threaded cortical bone dowel for which we are paid on a per unit basis, fees are
paid to us on a per donor basis for  processing,  finishing  and  packaging  our
clients'  mineralized,  weight-bearing  allograft bone tissue. In the Grafton(R)
DBM segment our clients pay us fees on a per unit basis. During 1998 MTF and ARC
accounted  for  approximately  56% and 39%,  respectively,  of our  consolidated
revenues.  We  receive  revenues  in both our  Grafton(R)  DBM and  Base  Tissue
segments from each of these clients. We have processing  agreements with MTF and
ARC which run through March 31, 2002 and December 31, 2006, respectively.

     We rely on our clients to obtain the donor  allograft  bone tissue which we
process and to distribute  the processed  allograft bone tissue to hospitals and
physicians for  transplantation.  We perform  marketing  services which generate
demand for our products. See "Education and Marketing."

     Our plasma spray  coating  customers and  non-allograft  bone tissue spinal
implant product customers  generally purchase our services and products pursuant
to purchase orders or  non-exclusive  supply  agreements which are cancelable at
any time by either party.

Education and Marketing

     Osteotech  believes the markets for  processed  allograft  bone tissue will
continue  to  be  orthopaedic,   neurological,  plastic  and  oral/maxillofacial
surgical specialties.  Our future growth in these areas will depend upon a wider
acceptance  by these  specialties  of the use of  allograft  bone  tissue  as an
alternative  to  autograft  bone  tissue  and  other  available   materials  and
treatments.

     As of December 31, 1998, we employed 21 persons engaged directly in efforts
to educate surgeons as to the benefits and  applications of processed  allograft
bone  tissue  and five  employees  to train our  independent  sales  agents.  We
complement our direct sales  organization with a national network of independent
sales agents who market  Grafton(R)  DBM, our bio-d(TM)  threaded  cortical bone
dowel and our non-allograft  bone tissue spinal implant  products.  These agents
also educate the medical  community  about processed  allograft bone tissue.  At
December 31,  1998,  we had  appointed  58 agencies  which employ over 230 sales
representatives.

     A small in-house  marketing  staff located at Osteotech's  Leiden  facility
markets its plasma spray coating services.  These marketing  activities  consist
primarily of attendance  at trade shows,  placement of  advertisements  in trade
journals and direct  mailings to orthopaedic  and dental implant  companies.  We
market our HA powders  and ceramic  products  directly  and through  independent
contract representatives in Europe.

Government Regulations

     Both of our Grafton(R) DBM and Base Tissue segments  involve the processing
of  human  tissue  intended  for  transplantation  and are  subject  to the same
regulations in the U.S.

     The procurement and  transplantation of allograft bone tissue is subject to
federal law pursuant to the National Organ  Transplant Act ("NOTA"),  a criminal
statute which  prohibits the purchase and sale of human organs,  including  bone
and related tissue,  for "valuable  consideration."  NOTA permits the payment of
reasonable  expenses  associated with the removal,  transportation,  processing,
preservation,  quality  control,  implantation and storage of human bone tissue.
Osteotech provides services in all of these areas, with the exception of removal
and implantation.

     The  FDA  currently  regulates  human  tissue-based  products  such  as the
allograft bone tissue  processed by Osteotech,  including  Grafton(R) DBM, under
certain  provisions  (Section  361) of the  Public  Health  Services  Act.  Such
products are not regulated as drugs,  medical devices or blood products,  but as
"human tissue for  transplantation."  FDA regulations do not require a premarket
clearance for such  products,  though these products are subject to tissue donor
screening  and  testing,  processing  and record  keeping,  and other  controls.
Tissue-based  and  cellular  products  that are not  classified  as human tissue
intended for  transplantation  will be regulated under different  regulations as
either drugs, devices or biologics.

     In August 1995,  the FDA  designated  Grafton(R) DBM as within the scope of
human tissue intended for  transplantation.  Human tissue such as  demineralized
bone  matrix  has been  considered,  and still is  considered,  exempt  from FDA
premarketing clearance requirements imposed upon medical products such as drugs,
devices and  biologics.  Grafton(R) DBM is a  demineralized  bone matrix that is
mixed with  glycerol,  a  basically  inactive  substance,  to provide  desirable
physical handling characteristics to the demineralized bone matrix.

     The FDA has proposed a more comprehensive  regulatory  framework that will,
if  adopted,  build  upon and  supersede  the  existing  regulations  for  human
tissue-based products. Implementation of this proposed regulatory approach would
lead to new  regulations  for the allograft bone tissue  processed by Osteotech.
One set of new  regulations  has already been  proposed via  publication  in the
Federal  Register  and  additional  proposed  regulations  are  expected  to  be
published in the Federal Register in the future.

     Allograft  bone tissue and tissue  processing  operations  are regulated in
most major  countries,  though with different  regulations and standards in each
country. In France, where Osteotech's subsidiary OST is located,  allograft bone
tissue is comprehensively  regulated by special  legislation.  In Germany,  such
products are regulated as pharmaceuticals.

     The LUBBOC(R) and LADDEC(R)  bovine grafts produced and marketed by OST are
regulated as medical devices in Europe and most other  international  markets in
which these products are marketed.


                                       13

<PAGE>


     The spinal implants, manufactured by Ulrich and distributed by Osteotech in
the U.S.,  are regulated as medical  devices  under the Federal  Food,  Drug and
Cosmetic Act.

     Osteotech's  European  HA  plasma  spray  coating  services  meet  existing
regulatory  requirements  in the  specific  countries  where they are  marketed.
Osteotech's   facility  in  Leiden,   The  Netherlands  has  received  ISO  9001
certification for its quality systems used in the development and manufacture of
ceramic products and ceramic and titanium spray coatings.  ISO certification for
production  facilities  were made mandatory in 1998 for companies that market or
distribute  products within the European Union. The certification was awarded by
Tuv Product Service, GmbH of Munich, Germany, a leading Notified Body in medical
devices,   following  a  series  of  audits.  Notified  Bodies  are  independent
organizations  authorized by the European  Union member  countries to administer
the ISO certification process.

     Ceramic  products  produced by Osteotech in The  Netherlands  are currently
distributed only in Europe. These products meet existing regulatory requirements
in the specific  countries where they are produced and marketed.  Osteotech does
not currently intend to market these products in the U.S.;  however,  if it does
decide to do so, these  products  would  require  premarket  clearance by FDA as
medical devices.

     HA powder  produced and sold in bulk by Osteotech in the U.S. and Europe is
considered to be a component  product and, as such, is not currently  subject to
regulation by the FDA and similar agencies in Europe.

Research and Development

     During 1998, 1997 and 1996, we spent approximately  $4,610,000,  $3,728,000
and  $4,357,000,  respectively,  on research  and  development  activities.  The
majority of these  expenditures  were made in both our  Grafton(R)  DBM and Base
Tissue segments.  We are engaged in continuing  research and development efforts
in the  allograft  bone tissue  processing  field which  include our  continuing
efforts to improve upon and maintain the safety and performance of the processed
allograft  bone tissue,  increase the amount of  transplantable  allograft  bone
tissue  derived from each donor,  reduce  processing  costs  through  efficiency
advances and develop new forms of allograft bone tissue.

Competition

     Market Overview

     The bone grafting market is an extension of the general orthopaedic surgery
market,  as bone grafts are used adjunctively in a broad range of reconstructive
orthopaedic  surgical  procedures  such as the repair of fractures  and skeletal
defects,  spinal  and joint  arthrodeses,  and  revision  arthroplasties.  These
procedures  are performed by virtually  all  orthopaedic  subspecialties  and by
neurosurgeons,  some plastic  surgeons and certain other  surgical  specialties.
Dental  and other  oral  maxillofacial  procedures  are not  considered  to be a
primary  portion  of the  bone  graft  market,  but are  instead  considered  to
constitute  a  secondary   market.   Three  basic   categories  of  products  or
alternatives currently compete in the bone graft market:

     o    autograft bone tissue;

     o    allograft bone tissue; and

     o    synthetic bone void fillers.

     A potential fourth product  category,  growth factor products,  is still in
the investigational stage.

     We estimate that total domestic  allograft bone tissue sales  increased 16%
in 1998 to $168  million,  comprising  approximately  35% of the U.S. bone graft
market.

     The number of bone graft procedures is forecast to increase during the next
five  years  due  to an  expected  increase  in  the  number  of  reconstructive
orthopaedic  surgical procedures  utilizing bone grafts,  particularly in spinal
procedures  using pedicle screw implants and spinal cages  recently  approved by
the FDA.

     Factors  producing  the  continued  growth in the number of  reconstructive
orthopaedic  surgical  procedures  that  incorporate  a bone graft  include  the
following:

     o    the aging of the U.S. population;

     o    improving  success rates for surgical  procedures  that involve a bone
          graft procedure;

     o    development  of  less  invasive  reconstructive  orthopaedic  surgical
          procedures that will be used in a wider patient population; and

     o    the   increasing   number  of  revision,   spinal   fusion  and  joint
          arthroplasty procedures.

     While the general bone graft market has experienced low-single-digit growth
in recent years,  we estimate that allograft bone tissue sales have increased at
an average annual rate of approximately 16% since 1994. This displacement  trend
is expected to continue as physicians gain  confidence in, and experience  with,
allograft bone tissue. Some of the factors  contributing to the increased use of
allograft bone tissue include:

     o    the desire by surgeons  to avoid the  additional  procedure  needed to
          acquire  autograft  bone tissue,  which often  increases  costs due to
          additional  operating  time,  medical  supplies and extended  hospital
          stay,  and  patient  risks due to  excessive  blood  loss,  infection,
          chronic pain and morbidity;

     o    increased  awareness by, and training of, the medical  community  with
          respect to the use and safety of processed allograft bone tissue;

     o    an increase  in the number of patients  who do not possess the quality
          of bone tissue  required for  autograft  procedures as a result of the
          general aging of the population; and

     o    an  increase  in the  availability  of  allograft  bone  tissue due to
          improved  recovery and  processing  techniques and an increase in bone
          tissue donations.

     Competitive Overview

     In both our Grafton(R) DBM and Base Tissue  segments we compete in the bone
graft  market  with  autograft  bone  tissue,  synthetic  bone void  fillers and
allograft  bone  tissue  processed  by  others,  primarily  bone  tissue  banks.
Autograft bone tissue has traditionally been the primary choice for surgeons and
we believe it still  maintains an  approximate  60% share of the U.S. bone graft
market.  Due to factors such as the increased  cost and potential  complications
associated with

                                       16

<PAGE>


an additional  procedure needed to acquire autograft bone tissue,  more surgeons
are beginning to choose  allograft  bone tissue over  autograft  bone tissue for
their bone grafting needs.

     Grafton(R) DBM Segment

     We have been  successful in persuading many surgeons to switch to Osteotech
processed  allograft bone tissue  through the  introduction  of our  proprietary
tissue  processing  technology.  Osteotech  has  expanded  the  applications  of
allograft bone tissue through  Grafton(R)  DBM, a proprietary  form of allograft
bone tissue. The demineralization process used in Grafton(R) DBM removes most of
the   minerals,   thus   exposing   the   proteins   that  promote  bone  growth
(osteoinduction)  and  creating a lattice  work for new bone  (osteoconduction).
Grafton(R) DBM has a validated viral  inactivation  process for HIV, hepatitis B
and C,  cytomeglia  and polio.  Grafton(R) DBM is produced in three forms - gel,
flex and putty - and packaged in sterile,  single patient delivery systems. With
the varying textural and handling characteristics of its three forms, Grafton(R)
DBM can be used in virtually all  non-weight-bearing  bone graft  procedures and
has been used in over 240,000  procedures  through  December 31, 1998. Given its
osteoinductive  and  osteoconductive  properties,  Grafton(R) DBM has a distinct
advantage  over  synthetic  bone  void  fillers,  all of which  are  exclusively
osteoconductive.

     Although it already  occupies a dominant  position  in the U.S.  market for
non-weight-bearing   grafting   materials,   Grafton(R)   DBM  has   significant
opportunities for growth. Currently, Grafton(R) DBM sales are almost exclusively
domestic.  Osteotech  estimates that  Grafton(R) DBM was used in only 14% of the
total bone graft  procedures  performed in the U.S. during 1998. We estimate the
potential  non-domestic bone graft market to be at least as large as that of the
U.S. market.  The European  market,  in particular,  provides  Osteotech with an
opportunity in an area where it already has a sales presence.

     Base Tissue Segment

     Allograft  bone  tissue is still the only  alternative  to  autograft  bone
tissue for bone grafting procedures which require weight-bearing tissue. We plan
to continue to  differentiate  our Base Tissue segment  operations from those of
other allograft bone tissue processors by expanding our viral inactivation claim
to include our  mineralized  weight-bearing  bone tissue during 1999. In 1999 we
will also  introduce  our  Allogard(R)  Packaging  plastic  tray for most of the
allograft bone tissue processed in our Base Tissue segment.  This packaging will
be easier for operating  room nurses to work with. In addition,  this will allow
us to  differentiate  our  "Osteotech  processed  bone"  from  most  competitive
allograft processed bone which is usually packaged in glass bottles.

     In order to maintain  our leading  position  in the  allograft  bone tissue
processing  market and to encourage  more surgeons to switch from autograft bone
tissue to Osteotech processed allograft bone tissue, we plan to:

     o    leverage our knowledge of allograft  bone tissue  processing to expand
          our proprietary tissue safety claims to our weight-bearing mineralized
          allograft bone tissue;

     o    expand  our  external  scientific  presence  through  publication  and
          presentation of clinical research and outcome studies;


                                       19

<PAGE>


     o    expand  our  market   differentiation   through   tissue   performance
          improvements,  including  line  extensions of existing base  allograft
          bone  tissue  products  and  new  product  introductions  such  as the
          bio-d(TM) threaded cortical bone dowel; and

     o    increase  education of surgeons  regarding  the use of allograft  bone
          tissue through expanded grand rounds, seminars and workshops.

     Other

     Osteotech's  ceramic  and  titanium  plasma  spray  coating  and HA product
operations face competition in Europe from divisions and subsidiaries of several
large corporations engaged in providing such services and products to others and
from several smaller independent  companies.  In addition,  Osteotech also faces
competition  from medical  implant  companies  which have in-house  plasma spray
coating  operations.  We compete  primarily  on the quality of our  coatings and
price.  We  believe  that the  spraying  technology  we use,  which is  computer
controlled and utilizes robotics, enables us to provide high quality coatings at
competitive prices. It should be noted,  however,  that the ceramic and titanium
coating industry is highly competitive,  certain of our competitors have greater
resources  than we do, and there can be no  assurance we will be able to compete
successfully.

Environmental Matters

     Osteotech's  allograft  bone  tissue  processing  generates  waste which is
classified  as  medical  hazardous  waste  by the  United  States  Environmental
Protection  Agency and the New Jersey  Department of  Environmental  Protection.
Such  waste is  segregated  by  Osteotech  and  disposed  of  through a licensed
hazardous  waste  transporter in compliance  with  applicable  regulations.  The
production of HA powder at  Osteotech's  facility in The  Netherlands  generates
small amounts of hazardous waste,  which is segregated by Osteotech and disposed
of through a licensed hazardous waste  transporter.  Although Osteotech believes
it is in compliance with applicable  environmental  regulations,  the failure by
Osteotech  to fully  comply  with  any  such  regulations  could  result  in the
imposition  of  penalties,  fines and/or  sanctions  which could have a material
adverse effect on Osteotech's business.

Patents and Proprietary Rights

     Osteotech  considers its processing  technology and procedures  proprietary
and relies primarily on trade secrets to protect its technology and innovations.
Significant   research  and  development   activities  have  been  conducted  by
consultants  employed  by third  parties  or in  conjunction  with  unaffiliated
medical institutions. Accordingly, disputes could arise in the future concerning
the proprietary  rights to information  applied to Osteotech projects which have
been  independently  developed by the  consultants or researchers at the medical
institutions.

     At February 28, 1999, Osteotech held (i) 30 United States patents and eight
foreign patents relating to its aseptic processing technology and its transplant
support products, including eight United States Grafton(R) DBM patents and three
foreign Grafton(R) DBM patents, (ii) four United


                                       20

<PAGE>


States and six foreign patents  relating to its biomaterials  technology,  (iii)
four United States and six foreign  patent  applications  relating to aspects of
its   processing   technology  and  its  osteogenic  and  other  products  under
development and (iv) three United States patent  applications  and three foreign
patent applications relating to its biomaterials technology.  Osteotech believes
that its  Grafton(R)  DBM patents are  significant  in  maintaining  Osteotech's
competitive position. These patents expire on various dates ranging from 2009 to
2016.  Osteotech's  other  patents  expire at various dates ranging from 2007 to
2017.

     There can be no assurance that any pending patent  applications will result
in issued patents or that any currently issued patents,  or patents which may be
issued,  will provide  Osteotech  with  sufficient  protection in the case of an
infringement  of its  technology or that others will not  independently  develop
technology  comparable  or  superior  to  Osteotech's.  Osteotech  is  currently
involved in two patent-related lawsuits. See Item 3. "Legal Proceedings."

Product Liability and Insurance

     The  testing  and use of  allograft  bone  tissue and the  implantation  of
medical devices coated with  Osteotech's HA powder,  medical  devices  developed
with  Osteotech's  biomaterials  technology and medical devices  manufactured by
others  and   distributed  by  Osteotech   entail   inherent  risks  of  medical
complications for patients, and therefore may result in product liability claims
against  Osteotech.   Further,  Osteotech's  agreements  with  its  bone  tissue
processing  clients  provide for  indemnification  by Osteotech for  liabilities
arising out of defects in allograft bone tissue caused as a result of processing
by Osteotech.

     As a distributor of implants and instruments for spinal surgery,  including
bone screws,  manufactured by Ulrich, Osteotech has been named as a defendant in
lawsuits in which  plaintiffs  claim that they have  suffered  damages  from the
implantation of allegedly defective spinal fixation devices.  See Item 3. "Legal
Proceedings."

     Pursuant to its distribution agreement with Osteotech, Ulrich has agreed to
indemnify  Osteotech  for  all  costs  and  damages  incurred  by  Osteotech  in
connection with its distribution of products manufactured by Ulrich, except such
costs and damages which are caused by  Osteotech's  gross  negligence or willful
misconduct or  unauthorized  claims made by Osteotech in marketing the products.
Ulrich maintains its own product liability insurance  coverage.  To date, Ulrich
has made indemnity  payments to Osteotech for a portion of the costs incurred by
Osteotech in defending the lawsuits involving the Ulrich products distributed by
Osteotech.  There can be no assurance that Osteotech will in fact be indemnified
by Ulrich for all such  costs.  See Note 8 of "Notes to  Consolidated  Financial
Statements."

     Osteotech  presently maintains product liability insurance in the amount of
$77  million  per  occurrence  and per year in the  aggregate.  There  can be no
assurance  that  Osteotech will be able to maintain such insurance in the future
or that such insurance will be sufficient to cover all liabilities.

Employees

     At December 31, 1998, Osteotech had 290 employees, of whom 181 were engaged
in  allograft  bone tissue  processing,  ceramic  plasma  spray  coating and the
manufacture of products;  27 were engaged in research and  development;  44 were
engaged in education and marketing;  and 38 were engaged in regulatory,  finance
and  administration.  Osteotech's  employees  are not covered by any  collective
bargaining  agreement.  Osteotech  considers  relations with its employees to be
good.

Item 2. Properties

     Osteotech's principal executive offices are located in approximately 38,000
square  feet in  Eatontown,  New Jersey,  which is occupied  pursuant to a lease
which  expires  in  December  2008 and  provides  for a base  annual  rental  of
approximately  $264,000.  This  facility is occupied by  Osteotech's  corporate,
financial,  administration,  marketing, research and development, regulatory and
clinical affairs staff. Both the Grafton(R) DBM and Base Tissue segments utilize
this facility.

     Osteotech's  processing facility is located in approximately  44,000 square
feet of space in Shrewsbury,  New Jersey,  which is occupied pursuant to a lease
which  expires  in  October  2008  and  provides  for a base  annual  rental  of
approximately  $367,000 through October 2003 and $410,000 for the remaining term
of the lease.  The lease is renewable at  Osteotech's  option for an  additional
five year term.  Both the Grafton(R) DBM and Base Tissue  segments  utilize this
facility.

     Osteotech's European  subsidiaries engaged in the biomaterial business line
occupy a 21,000 square foot facility in Leiden,  The Netherlands.  The lease for
this  facility  expires  in  May  2008  and  the  annual  rent  is  dfl  626,000
(approximately  $333,000  at  the  December  31,  1998  exchange  rate).  We are
subleasing  2,200 square feet of this facility to an unrelated third party at an
annual  rent of dfl  111,500  (approximately  $59,000 at the  December  31, 1998
exchange rate).

     In 1997, Osteotech purchased approximately 13 acres of land surrounding its
Eatontown,  New  Jersey  facility.  We plan to  utilize  this  land  for  future
expansion to meet our anticipated  facilities  requirements.  In connection with
the first  stage of this  expansion,  we have  engaged a  developer  to build an
additional  65,000 square foot  processing  facility to our  specifications.  We
expect to  occupy  this  facility  in the first  quarter  of 2000.  We intend to
finance the construction of this facility with a $4.5 million loan from our bank
which will be secured by a mortgage on the real property,  building and fixtures
and with a $17  million  equipment  line of credit  from our bank  which will be
secured by the equipment  purchased  with the proceeds from this loan  facility.
These loans are subject to the  negotiation  and  execution of  definitive  loan
agreements.

Item 3. Legal Proceedings

GenSci Laboratories,  Inc. v. Osteotech,  Inc., Case No. SACV 9868 AHS Eex (C.D.
Cal.)

     As  previously  reported,  Osteotech  filed suit on January 16, 1998 in the
United  States  District  Court for the  District of New Jersey  against  GenSci
Regeneration  Sciences,  Inc.  and  GenSci  Laboratories,   Inc.  (collectively,
"GenSci")  for patent  infringement  and GenSci  filed suit on January  28, 1998
against  Osteotech in the United States District Court for the Central  District
of California for patent  infringement,  tortious  interference  with a business
expectancy, negligent interference with prospective economic advantage, inducing
breach of contract and a declaratory  judgement of the invalidity of Osteotech's
patents U.S. Patent Nos. 5,284,655 and 5,290,558. On August 10, 1998 these cases
were  consolidated into one case before the United States District Court for the
Central  District  of  California  under Case  Number  SACV 9868 AHS (EE x) (the
"Action").

     In September,  1998 we commenced a third party action  against DePuy Motech
Inc.,  alleging that DePuy Motech,  Inc., through the marketing and distribution
of DynaGraft  Gel and DynaGraft  Putty,  is acting  jointly and  severally  with
GenSci in infringing  on the claims of our patents.  Although  monetary  damages
have been requested, an amount has not been specified.

     Discovery on all of the claims  asserted in this  litigation  has commenced
and is ongoing.

     Osteotech has and will continue to vigorously defend any claims against it,
prosecute  the  claims  it  has  asserted  in the  Action,  and  vigorously  and
affirmatively  protect its  products  and  intellectual  property to the fullest
extent possible under the law.

"O" Company, Inc. v. Osteotech, Inc., Case No. Civ. 98-981 BB/LFG (D.N.M.)

     On August 14,  1998,  Osteotech  removed  this action to the United  States
District  Court for the District of New Mexico,  where it has been assigned Case
No. Civ. 98-981 BB/LFG. As previously  reported,  the plaintiffs in this action,
manufacturers  and  distributors  of dental  implants,  alleged causes of action
claiming   negligence,   strict   liability,   breach  of  warranty,   negligent
misrepresentation,  fraud and violation of the New Mexico Unfair Trade Practices
Act,  arising from  allegedly  defective  ceramic  coating and coating  services
provided to  plaintiffs  by a  subsidiary  of  Osteotech,  Cam  Implants BV. The
plaintiffs have demanded unspecified damages from Osteotech. On August 24, 1998,
Osteotech  served and filed its answer,  denying any and all  liability  in this
action.  Based upon a motion  made by  Osteotech  on March 16,  1999,  the court
dismissed with prejudice plaintiffs' negligence and strict liability claims.

     On November 5, 1998,  Osteotech moved for summary  judgment in its favor on
all of the claims alleged in this action,  on the ground that all of plaintiffs'
claims are barred by their applicable statutes of limitations. The court has not
yet decided that motion. To date, the court has limited discovery in this action
to matters related to the statute of limitations issue.

Orthopaedic Bone Screw Products Liability Litigation

     As of March 26,  1999,  Osteotech  remains a  defendant  in two  previously
reported state court  products  liability  actions  involving  orthopaedic  bone
screws:  Abercrombie v. Acromed Corp.,  CV-298393 (Ct. of Common Pleas, Cuyahoga
County,  Ohio); and Ponder v. Synthes,  Case No. 960602729 (Ct. of Common Pleas,
Philadelphia County, Pa.). The Ponder action remains stayed.

     In Abercrombie,  more than 1,800 of the original plaintiffs dismissed their
claims  against  Osteotech  on October 28, 1998.  On January 15, 1999,  the nine
remaining  plaintiffs  moved to amend their  complaint  against the 28 remaining
defendants, including Osteotech, to assert claims of civil conspiracy.

     Osteotech continues to believe that both actions are without merit and will
continue to vigorously defend both lawsuits.

     Both of the  actions  seek  monetary  damages of no less than  $50,000  per
plaintiff.  The  aggregate  money  damages  eventually  sought  by  all  of  the
plaintiffs  and the  related  costs to defend such  actions may be  substantial.
Pursuant to Osteotech's  distribution agreement with Ulrich, the manufacturer of
the spinal  system  distributed  by  Osteotech  which is the basis for these two
actions  against  Osteotech,  Ulrich  has  agreed  to  indemnify  Osteotech  for
liabilities  incurred in connection with the distribution of Ulrich's  products.
However, there can be no assurance that Ulrich will have the financial resources
necessary to comply with its indemnification obligations to Osteotech.

University of Florida Tissue Bank, Inc. v. Osteotech, Inc., Case No. 1:99cv33
MMP (N.D. Fla.)

     On or about March 3, 1999, Osteotech received a complaint that was filed in
the  United  States  District  Court for the  Northern  District  of  Florida on
February 25, 1999. This action, which has been brought by plaintiffs, University
of Florida Tissue Bank, Inc.,  Regeneration  Technologies,  Inc.,  Sofamor Danek
Group, Inc., and Sofamor Danek L.P., alleges that Osteotech's bio-d(TM) threaded
cortical  bone dowel and  Endodowel  infringe  on the claims of U.S.  Patent No.
5,814,084,  entitled "Diaphysical Cortical Dowel." Although monetary damages are
sought, an amount has not been specified.

     Based upon  reviews  conducted  by its outside  patent  counsel,  Osteotech
believes  that its bio-d(TM)  threaded  cortical bone dowel and Endodowel do not
infringe  the patent  asserted in the action.  Osteotech  intends to  vigorously
defend the action.

(1)  On February 11, 1999,  the Board of  Directors  authorized a  three-for-two
     stock split in the form of a 50% stock  dividend  that was  distributed  on
     March 19, 1999 to stockholders of record on March 5, 1999. The high and low
     sales  prices have been  restated to give  retroactive  recognition  to the
     stock split for all periods presented.

     As of March,  1999 there were 234 holders of record of  Osteotech's  Common
Stock.  Osteotech believes that there are approximately  4,900 beneficial owners
of its Common Stock.

     Osteotech  has  never  paid a cash  dividend  and does not  anticipate  the
payment of cash dividends in the foreseeable  future as earnings are expected to
be retained to finance  Osteotech's  growth.  Declaration  of  dividends  in the
future will remain  within the  discretion  of  Osteotech's  Board of Directors,
which will review Osteotech's dividend policy from time to time.

Item 7. Management's Discussion And Analysis Of Financial Condition And Results
        Of Operations

For the Three Years Ended December 31, 1998, 1997 and 1996

Results of Operations

     All per share data have been adjusted for the three-for-two  stock split in
the form of a 50% stock dividend in March 1999.

     Net Income (Loss)

     Consolidated net income for 1998 was $10,304,000 or $.73 diluted income per
share,  compared to net income of $5,686,000 or $.43 diluted income per share in
1997 and a net loss of $324,000 or $.03 diluted loss per share in 1996.

     Consolidated  income before income taxes  increased to  $17,413,000 in 1998
compared to  $9,572,000  in 1997 and  $2,020,000  in 1996.  Income before income
taxes in 1996  includes  a charge  to  earnings  of  $1,350,000  related  to the
restructuring  of  our  operations  located  in  Leiden,  The  Netherlands.  See
"Provision for Restructuring" included below.

     The  following is a discussion of factors  affecting  results of operations
for the years ended December 31, 1998, 1997 and 1996.

     Net Revenues

     Consolidated  net  revenues  in  1998  were  $59,201,000,  an  increase  of
$14,270,000  or 32% from  1997.  The  increase  was  principally  due to  higher
revenues in both the Grafton(R) DBM and Base Tissue segments. Domestic revenues,
which consist  principally  of revenues from the  Grafton(R) DBM and Base Tissue
segments,  increased 36%, and foreign  revenues  decreased 24% compared to 1997.
The decline in foreign  revenues  resulted  primarily from decreased unit volume
for our ceramic products.

     Grafton(R) DBM segment  revenues in 1998 were  $39,128,000,  an increase of
$12,475,000 or 47% compared with the prior year, as a result of increased demand
for Grafton(R) DBM. Base Tissue segment revenues were $17,323,000, or 20% higher
than prior year  revenues  of  $14,426,000,  as a result of the  increased  unit
volume of allograft bone tissue which we processed for our clients.

     Consolidated  net  revenues  in  1997  were  $44,931,000,  an  increase  of
$10,036,000  or 29% over 1996  consolidated  net  revenues of  $34,895,000.  The
increase was  principally  due to higher revenues in the Grafton(R) DBM segment,
which  increased 74% to  $26,653,000  from  $15,293,000  in 1996, as a result of
increased  demand  for  Grafton(R)  DBM.   Domestic   revenues,   which  consist
principally  of  revenues  from the  Grafton(R)  DBM and Base  Tissue  segments,
increased 33% and foreign revenues decreased 8% compared to 1996. The decline in
foreign revenues resulted

                                       27

<PAGE>


primarily from a decrease in research grant revenues from the Dutch  government,
as a result of the  discontinuance  of our  PolyActive(TM)  polymer research and
development  program.  See "Provision for Restructuring"  below. During 1997, we
licensed out the patents and technology  related to PolyActive(TM)  and received
an upfront  payment of  $257,000,  which  partially  offset the decline in grant
revenues.  Additionally,  foreign revenues in 1997 were unfavorably impacted 14%
as a result of the strength of the U.S.  dollar  compared to the Dutch  Guilder.
However, the impact on consolidated net revenues was approximately 1%.

     Base Tissue segment revenues decreased 3% in 1997 as compared with 1996. In
1997, we discontinued  providing certain contract testing services to one of our
clients, which accounted for this decrease in revenues.

     During 1998,  1997 and 1996,  two of our clients in the  Grafton(R) DBM and
Base Tissue  segments  accounted  for 56% and 39%,  57% and 34% and 64% and 25%,
respectively,  of consolidated net revenues.  Effective in 1997, we entered into
new long-term exclusive processing agreements with both of these clients.

     Costs of Services and Products

     Costs of services as a percentage of service  revenues was 29% in 1998, 34%
in 1997 and 39% in 1996.  The  decline  in costs  as a  percentage  of  revenues
results from a shift in revenue mix toward  services with higher gross  margins,
operating  efficiencies  resulting from increased volume and an increase in fees
charged to our clients for Grafton(R) DBM. We expect that consolidated  costs as
a percentage of consolidated revenues will increase  approximately 2% in 1999 as
a result of increased  processing expenses associated with the implementation of
viral inactivation technology in the Base Tissue segment.

     Cost of products as a percentage of product  revenues was 80% in 1998,  75%
in 1997 and 97% in 1996.  The  increase  in  costs  in 1998 as a  percentage  of
revenues  resulted  principally from a decrease in revenues from certain ceramic
products and  non-allograft  bone tissue spinal  implant  products,  while fixed
costs remained the same. The decline in costs as a percentage of revenue in 1997
resulted primarily from a shift in product mix toward products with higher gross
margins.

     Marketing, General and Administrative Expenses

     Marketing,  general and administrative expenses increased $4,290,000 or 26%
in 1998 and $3,762,000 or 30% in 1997. The increases are primarily  attributable
to the Grafton(R) DBM segment and result from expanded marketing and promotional
activities and increased  agent  commissions  resulting  from increased  volume.
Additionally,  corporate  administrative  costs  increased  compared  with 1997,
principally as a result of higher outside professional costs.


                                       28

<PAGE>


     Research and Development Expenses

     Research  and  development  expenses in 1998  increased  $882,000 or 24% to
$4,610,000 from  $3,728,000 in 1997. The increase was primarily  attributable to
increased  spending in the Base Tissue  segment  associated  with the  continued
development of a viral inactivation  process and development of allograft tissue
products and services,  including the  bio-d(TM)  threaded  cortical bone dowel.
Research  and  development  expenses  in  1997  decreased  $629,000  or  14%  to
$3,728,000  from $4,357,000 in 1996. The decline  results  principally  from the
discontinuance of our PolyActive(TM) polymer research and development program in
the fourth quarter of 1996. See "Provision for Restructuring" below.

     Provision for Restructuring

     In October 1996, we announced a plan to restructure our operations  located
in Leiden,  The Netherlands in order to focus those operations on: (i) providing
ceramic  and  titanium  spray  coating  services  and  ceramic  products  to the
orthopaedic and dental markets and (ii) to pursue OEM business opportunities for
those  technologies.  In connection with the restructuring,  we discontinued our
PolyActive(TM)  polymer  research and  development  program.  As a result of the
restructuring,  we recorded a pre-tax restructuring charge of $1,350,000,  which
included  $425,000 for employee  termination  costs,  $541,000 for  write-off of
equipment,  intangible assets and inventory,  $234,000 for costs associated with
the planned  sub-leasing  of office space in Leiden on which we have a long-term
lease, and $150,000 for other contractual  obligations.  See Note 4 of "Notes to
Consolidated Financial Statements."

     Operating Income

     Operating income increased $7,249,000 or 81% in 1998 and $7,238,000 or 414%
in 1997. The increase in both periods results primarily from improved  operating
income in the Grafton(R) DBM segment resulting from increased revenues discussed
above.  Grafton(R) DBM segment  operating income increased  $6,442,000 or 93% in
1998 and $4,241,000 or 156% in 1997. Operating income in 1997 also improved as a
result of the  restructuring  of the foreign  operations in 1996. See "Provision
for Restructuring" above.

     Other Income (Expense)

     In 1998 and 1997, other income increased by $547,000 and $314,000  compared
to  1997  and  1996,  respectively,  due  to  higher  invested  cash  and  lower
outstanding debt balances.

     Income Tax Provision

     Our  effective  income  tax rate was 41% in 1998 and 1997 and 116% in 1996.
The high effective income tax rate in 1996 was principally due to foreign losses
for which no  current  tax  benefits  were  available.  See Note 13 of "Notes to
Consolidated Financial Statements."

Liquidity and Capital Resources

     At December 31, 1998, we had cash and short-term investments of $18,041,000
compared to  $15,357,000 at December 31, 1997. We invest our excess cash in U.S.
Government-backed securities and investment grade commercial paper of major U.S.
corporations.  Working capital  increased  $6,451,000 to $26,373,000 at December
31, 1998 compared to  $19,922,000 at December 31, 1997.  Accounts  receivable at
December 31, 1998 increased $4,433,000 due to revenue increases.

     Net cash provided by operating  activities  was $8,338,000 in 1998 compared
to $6,564,000 in 1997. The increase resulted primarily from improved earnings in
1998, partly offset by the increase in accounts  receivable  discussed above and
an increase in deferred processing costs. Cash used for capital  expenditures in
1998 was $5,521,000 and resulted from our continued investment in facilities and
equipment needed for current and future business requirements. During the fourth
quarter of 1998,  we  commenced  construction  of a new  processing  facility in
Eatontown,  New Jersey. See Item 2.  "Properties." The estimated  aggregate cost
for  the  construction  of  the  facility,  including  furniture,  fixtures  and
equipment, is approximately $25,000,000,  of which $21,500,000 we expect will be
funded by our current bank through a building  mortgage loan and equipment  line
of credit.  The remaining balance of $3,500,000 will be funded through available
cash reserves or  anticipated  cash flow from  operations.  Net cash provided by
financing  activities  was  $616,000 in 1998  compared  to net cash  provided by
financing  activities of $5,048,000 in 1997. Both periods include  proceeds from
stock  option  exercises  and tax  benefits  resulting  from these stock  option
exercises.  The net cash  provided  by  financing  activities  in 1998 is net of
$4,958,000  used to repurchase  and retire 367,500 shares of our common stock in
1998.

     We presently have a loan and security  agreement  with a U.S.  bank,  which
provides for borrowings of up to $3,000,000 under a revolving line of credit and
$4,000,000 under an equipment line of credit. At December 31, 1998, $172,000 was
outstanding  under the  equipment  line of credit and there  were no  borrowings
outstanding  under the revolving line of credit.  The existing  credit  facility
will be  replaced  in 1999  with a new  credit  facility  that  will  include  a
$5,000,000  revolving  line of credit in  addition to the  $21,500,000  building
mortgage loan and equipment line of credit discussed above.  Consummation of the
new credit  facility is subject to  negotiation  and  execution  of a definitive
agreement.  We also have a line of credit with a Dutch bank,  which provides for
borrowings of up to dfl 5,000,000,  or approximately  $2,659,000 at the December
31, 1998 exchange rate.  Analysis of our cash position and anticipated cash flow
indicated  that it most likely would not be  necessary to utilize a  significant
portion of this line of credit in 1998 and,  therefore,  we agreed with the bank
to limit our borrowings, if any, to no more than dfl 3,000,000, or approximately
$1,595,000 at the December 31, 1998 exchange  rate. At December 31, 1998,  there
were no borrowings  outstanding under this credit line. See Note 11 of "Notes to
Consolidated Financial Statements."

     At December 31, 1998  certain of our  foreign-based  subsidiaries  have net
operating  loss  carryforwards  aggregating  $2,478,000 at the December 31, 1998
exchange rate ($324,000 with no

                                       30

expiration date;  $2,154,000  expiring 2004 through 2006). See Note 13 of "Notes
to Consolidated Financial Statements."

     We believe that our cash and cash equivalents,  short-term  investments and
available  lines of credit,  together  with  anticipated  future  cash flow from
operations, will be sufficient to meet our near-term requirements.  From time to
time, we may seek additional  funds through equity or debt  financing.  However,
there can be no assurance that such additional funds will be available to us or,
if available, that such funds will be available to us on favorable terms.

Impact of Inflation and Foreign Currency Exchange Fluctuations

     The  results  of  operations  for  the  periods  discussed  have  not  been
materially affected by inflation or foreign currency fluctuations.

Litigation

     Osteotech  is  involved  in various  legal  proceedings  involving  product
liability and patent  infringement  claims.  For a complete  discussion of these
matters,  see Item 3. "Legal  Proceedings"  and Note 8 of "Notes to Consolidated
Financial  Statements."  It is  possible  that  our  results  of  operations  or
liquidity  and capital  resources  could be  adversely  affected by the ultimate
outcome of the pending litigation or as a result of the costs of contesting such
lawsuits.

Year 2000

     We  recognize  the need to ensure that Year 2000 issues will not  adversely
impact our operations and have  identified our potential Year 2000 risk in three
categories:  internal  business  software and hardware;  internal  non-financial
systems; and noncompliance by suppliers and customers.

     Internal Business Software and Hardware

     Several  years ago we  determined  that our existing  business  information
systems  were not  adequate to support the  anticipated  growth in our  business
operations and as a result purchased a fully integrated  management  information
system,  which is Year 2000 compliant.  Most of the new system is operational at
this time and the remainder of the system is scheduled to be operational in June
1999. The completion cost for  implementation  of the remaining  software is not
expected to be material.  All related hardware used to support internal business
software is currently Year 2000 compliant.  As a result,  we do not believe that
we require a contingency plan with respect to our internal business systems, and
therefore  have  not  developed  one.  However,  if  we  subsequently   identify
significant risks we will develop  contingency plans as deemed necessary at that
time.


                                       31

<PAGE>


     Internal Non-financial Systems

     We have  completed our  assessment of our internal  non-financial  systems,
such as office  equipment,  security systems and other business  equipment,  and
determined that minimal changes are required for Year 2000 compliance. We expect
to be in full compliance with our internal non-financial systems before the year
2000 and the cost to achieve such compliance is not expected to be material.

     Noncompliance by Suppliers and Customers

     We  have  initiated  written  communications  with  all of our  significant
suppliers and  customers to determine  the extent to which we are  vulnerable to
those third parties' failure to achieve Year 2000  compliance.  We are currently
evaluating  the  responses  and,  if there  are any  affected  suppliers  and/or
customers, will develop contingency plans in order to minimize disruption to our
business  operations.  At this time we cannot  estimate the additional  cost, if
any, that may result from such contingency plans.

     Risk of Non-Compliance

     Based on the progress we have made in  addressing  Year 2000 issues,  we do
not foresee  significant risks associated with our Year 2000 compliance  program
at this time.  Although we expect to be compliant before the Year 2000, there is
no guarantee  that these  results will be  achieved.  Partial or total  business
systems  interruption or the inability of a significant  supplier or customer to
achieve  Year  2000  compliance  could  have a  material  adverse  effect on our
business  operations,  financial  condition,  results of operations and business
prospects.

Risk Factors

     Two primary clients provide the bulk of our revenues

     We are the exclusive  processor of allograft bone tissue for large national
and  international  not-for-profit  organizations.  During  1998,  MTF  and  ARC
accounted for  approximately  56% and 39%,  respectively,  of our  revenues.  We
entered into a 10-year exclusive  processing agreement with ARC in December 1996
and a five-year exclusive  processing agreement with MTF in April 1997. The loss
of either  MTF or ARC as a client or a  substantial  reduction  in the amount of
allograft  bone tissue which we process for either  entity would have a material
adverse effect on our business, financial condition and results of operations.

     Our dependence  upon a limited supply of human donors may curtail  business
expansion

     Our allograft bone tissue processing business depends upon the availability
of bone and  related  connective  tissue  from  human  donors  recovered  by our
clients.  We rely on the efforts of not-for-profit  donor procurement  agencies,
including  our current  clients,  to educate the public and foster an  increased
willingness to donate bone tissue. These organizations may not be able to find a
sufficient  number of  persons  to donate  sufficient  amounts of tissue to meet
present or future


                                       32

<PAGE>



demand for either  allograft  bone  tissue or any  allograft  bone  tissue-based
osteogenic  materials  we are  developing.  In the event  that we are  unable to
secure enough donors to meet our demands, our business,  financial condition and
results of operations may suffer a material adverse effect.

     Our  revenues  will  depend  upon  reimbursement  from  public and  private
insurers

     The continued ability of our clients to pay our processing  charges depends
upon our clients'  ability to  distribute  processed  allograft  bone tissue and
collect fees from their clients,  which are typically medical institutions.  The
ability of medical  institutions  to pay fees to our clients  depends in part on
the extent to which  reimbursement  for the costs of such  materials and related
treatments will continue to be available from government  health  administration
authorities,  private health coverage insurers and other  organizations.  We may
have  difficulty  gaining  market  acceptance  for our  products and services if
government  and  third-party   payors  do  not  provide  adequate  coverage  and
reimbursement.

     Medical  community  could  choose  not to use  our  allograft  bone  tissue
products

     We believe the market for  allograft  bone  tissue will  continue to derive
from the use of such products by  physicians  specializing  in the  orthopaedic,
neurological,  plastic and oral/maxillofacial  surgical areas. Our future growth
depends in part upon such  physicians'  wider use of allograft bone tissue as an
alternative  to  autograft  bone  tissue  and  other  available   materials  and
treatments.   We  have  tried  to  educate   physicians  through  our  marketing
activities. Although our education and marketing efforts to date have enabled us
to expand our business,  our future  efforts in this regard may fail to generate
additional demand.

     Governmental  regulation of organ transplantation could restrict the use of
our products

     The procurement and transplantation of allograft bone tissue are subject to
federal  regulation  pursuant to NOTA, a criminal  statute  which  prohibits the
purchase  and sale of human  organs,  including  bone and  related  tissue,  for
"valuable  consideration."  NOTA  permits  the  payment of  reasonable  expenses
associated with the removal, transportation,  processing,  preservation, quality
control,  implantation and storage of human bone tissue.  We provide services in
all of these areas,  with the exception of removal and  implantation.  Osteotech
and other  allograft  bone  tissue  processors  are  engaged in ongoing  efforts
designed to educate  the  medical  community  as to the  benefits  of  processed
allograft bone tissue and we will continue to expand our educational activities.
Although  we believe  that NOTA  permits  reimbursement  of these costs as costs
associated with the processing, transportation and implantation of our allograft
bone tissue products,  our inability to be reimbursed for our education  efforts
in the future could  adversely  affect our business  and  prospects.  No federal
agency or court has determined  whether NOTA is, or will be, applicable to every
allograft  bone  tissue-based  material which our  processing  technologies  may
generate. Assuming that NOTA applies to Osteotech's processing of allograft bone
tissue,  we believe that we comply with NOTA, but there can be no assurance that
more restrictive  interpretations of, or amendments to, NOTA will not be adopted
in the future  which would call into  question one or more aspects of our method
of operations.


                                       33

<PAGE>


     Loss of key persons could limit our success

     Our success  depends  upon the  continued  contributions  of our  executive
officers and scientific and technical  personnel.  The competition for qualified
personnel  is  intense,   and  the  loss  of  services  of  our  key  personnel,
particularly members of senior management, could adversely affect our business.

     Inability to enforce our patents or findings that we infringe  patents held
by others could damage our business

     Osteotech  considers its allograft  bone tissue  processing  technology and
procedures  proprietary  and relies  primarily  on trade  secrets and patents to
protect its technology and  innovations.  Consultants  employed by third parties
and persons working in conjunction with medical  institutions  unaffiliated with
us have  conducted  significant  research  and  development  for  our  products.
Accordingly, disputes may arise concerning the proprietary rights to information
applied  to our  projects  which  have  been  independently  developed  by  such
consultants  or medical  institutions.  In addition,  you should  recognize that
although we have attempted to protect our technology with patents,  our existing
patents may prove invalid or unenforceable  as to products or services  marketed
by our  competitors.  Our pending patent  applications  may not result in issued
patents.  Moreover,  due to  continuous  changes  as a result  of  research  and
development,  we could  inadvertently  infringe  the  patents of others.  We are
currently involved in two lawsuits in which we are accused of infringing patents
held by others. See Item 3 "Legal Proceedings."

     Firms with  greater  financial  resources  and lower costs  present  strong
competitive threat

     The allograft bone tissue we process competes in the bone graft market with
autograft  bone tissue,  synthetic  bone void fillers and allograft  bone tissue
processed  by  others,   primarily  tissue  banks.  Autograft  bone  tissue  has
traditionally been the primary choice for surgeons and we believe autograft bone
tissue still maintains  approximately  60% share of the United States bone graft
market.  Certain of our competitors have greater financial resources than we do.
For  numerous  circumstances  and  procedures  for which  autograft  bone tissue
transplantation  is either not feasible or not desirable,  there are a number of
competing alternatives  available,  including allograft bone tissue processed by
others.

     We believe  that a majority of the  cadaveric  bone banks  operating in the
United   States  are   engaged  in   processing   allograft   bone   tissue  for
transplantation. Substantially all of these bone tissue banks are not-for-profit
organizations, and, as such, they may be able to supply processing services at a
lower  cost  than we can.  We  compete  with such  entities  on the basis of our
advanced  processing  technology and the quality and quantity of the bone tissue
our processing yields.  Since we introduced our allograft bone tissue processing
technology in 1987, certain competing  processors have claimed to have developed
technology  similar to that which we use.  Although we  believe,  based upon our
knowledge of the industry, that we process bone tissue from more donors than any
other processor in the world,  there can be no assurance that we can continue to
compete successfully in the area of allograft bone tissue processing.


                                       34

<PAGE>


     Competitive threat from alternate technologies

     The primary  advantage of synthetic  bone  substitutes  is that they do not
depend on the availability of human donors. In addition,  members of the medical
community and the general public may perceive synthetic  materials as safer than
allograft-based  bone  tissue.  The  allograft  bone  tissue we  process  may be
incapable  of  competing   successfully  with  synthetic  bone  substitutes  and
recombinant  bone growth  factors  which are  developed  and  commercialized  by
others,  which could have a material  adverse effect on our business,  financial
condition and results of operations.

     Risk to spray coating and HA product operations of competition

     Our plasma spray  coating and HA product  operations  face  competition  in
Europe from divisions and subsidiaries of several large corporations  engaged in
providing  such  services  and  products  to  others  and from  several  smaller
independent  companies.  In  addition,  we also face  competition  from  medical
implant  companies  which have  in-house  plasma spray  coating  operations.  We
compete primarily on the quality of our coatings and our prices. We believe that
the  spraying  technology  we use,  which is  computer-controlled  and  utilizes
robotics, enables us to provide high quality coatings at competitive prices. You
should note,  however,  that the ceramic coating industry is highly competitive,
certain of our  competitors  have  greater  resources  than we do, and we may be
unable to compete successfully.

     Potential losses from product liability lawsuits

     The testing and use of human allograft bone tissue and the  implantation of
medical  devices  coated  with our HA powder or  titanium  and  medical  devices
manufactured by others and which we distribute, entail inherent risks of medical
complications  for patients and therefore may result in product liability claims
against us. Further,  our agreements  with our allograft bone tissue  processing
clients provide for indemnification by us for liabilities arising out of defects
in allograft bone tissue caused by our processing.

     As a distributor of implants and instruments for spinal surgery,  including
bone screws,  manufactured  by Ulrich,  we are currently named as a defendant in
two lawsuits in which  patients  claim that they have suffered  damages from the
implantation of allegedly defective spinal fixation devices. Although we believe
that we will  ultimately  prevail in these cases,  litigation is subject to many
uncertainties and it is possible that some of the pending cases could be decided
against  us. The  ultimate  outcome of the  pending  litigation  or the costs of
contesting  such  suits  could  materially   adversely  affect  our  results  of
operations or liquidity and capital resources if the ultimate  liability exceeds
the amount  that we recover  from Ulrich  pursuant  to Ulrich's  indemnification
obligation  to us. We are unable to estimate the  potential  liability,  if any,
that may result  from the  pending  litigation  and,  accordingly,  have made no
provision  for any  possible  future  liability  in the  consolidated  financial
statements. See Item 3 "Legal Proceedings."


                                       35

<PAGE>


     We  presently  maintain  product  liability  insurance in the amount of $77
million  per  occurrence  and per year in the  aggregate.  We may be  unable  to
maintain  such  insurance  in the  future and such  insurance  may not cover all
liabilities.

     Potential lawsuit or governmental enforcement based on hazardous waste

     Our bone tissue  processing  generates waste which is classified as medical
hazardous waste by the United States Environmental Protection Agency and the New
Jersey  Department  of  Environmental  Protection.  We segregate  such waste and
dispose of it through a licensed  hazardous waste transporter in compliance with
applicable  regulations.  The  production  of HA powder at our  facility  in The
Netherlands  generates small amounts of hazardous waste,  which we segregate and
dispose of through a licensed hazardous waste transporter.

     Although  we believe we are in  compliance  with  applicable  environmental
regulations,  our failure to fully comply with any such regulations could result
in the  imposition  of  penalties,  fines  and/or  sanctions  or, in some cases,
private  lawsuits,  which could have a material  adverse effect on our business,
financial condition and results of operations.

                        REPORT OF INDEPENDENT ACCOUNTANTS



The Board of Directors and
  Stockholders of Osteotech, Inc.:


In our opinion,  the  accompanying  consolidated  balance sheets and the related
consolidated statements of operations,  changes in stockholders' equity and cash
flows  present  fairly,  in all material  respects,  the  financial  position of
Osteotech Inc. and  Subsidiaries  (the "Company") at December 31, 1998 and 1997,
and the results of their  operations  and their cash flows for each of the three
years in the period ended  December  31,  1998,  in  conformity  with  generally
accepted   accounting   principles.   These   financial   statements   are   the
responsibility of the Company's management;  our responsibility is to express an
opinion on these  financial  statements  based on our audits.  We conducted  our
audits of these  statements  in  accordance  with  generally  accepted  auditing
standards which 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,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   DESCRIPTION OF BUSINESS

     Osteotech,  Inc. (the "Company") provides services and develops and markets
     products to the orthopaedic, neurological,  oral/maxillofacial,  dental and
     general  surgery  markets in the United  States and Europe.  The  Company's
     current technology, products and services, and those under development, are
     focused primarily on the repair and healing of the musculoskeletal  system.
     Osteotech is engaged in the  processing  of human bone and bone  connective
     tissue  (collectively,  "allograft bone tissue") used for  transplantation.
     The  Company   has  two  primary   operating   segments:   the   Grafton(R)
     Demineralized  Bone Matrix (DBM) segment (the "Grafton(R) DBM segment") and
     Base Allograft Bone Tissue segment (the "Base Tissue segment"). In addition
     to these two primary  segments,  the Company  provides ceramic and titanium
     plasma  spray  coating   services  to   orthopaedic   and  dental   implant
     manufacturers and markets and distributes  non-allograft bone tissue spinal
     implant products.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Consolidated Financial Statements

     The consolidated  financial  statements  include the accounts of Osteotech,
     Inc., its majority-owned  subsidiaries and joint ventures controlled by the
     Company. Investments in less than 20% owned affiliates are accounted for on
     the cost method. All intercompany  transactions and balances are eliminated
     in consolidation.

     Revenue Recognition

     Revenue is  recognized at the time the Company  ships  processed  allograft
     bone tissue or products to its clients.

     License  fee  revenues  is  recognized  when  all  significant  contractual
     obligations have been satisfied.

     Grant revenues are recognized when earned. Grant revenues are considered to
     be  earned  in  the  period  that   qualifying   research  and  development
     expenditures are incurred and reflected in the  Consolidated  Statements of
     Operations.

     Cash Equivalents and Short-Term Investments

     The  Company   considers  all  highly  liquid   investments  with  original
     maturities of three months or less to be cash equivalents. Investments with
     maturities in excess of three months but less than one year are  classified
     as short-term  investments  and are stated at cost, net of any  unamortized
     premiums or discounts, which approximates fair value.

     Inventories

     Inventories are stated at the lower of cost or market, with cost determined
     under the first-in, first-out method.

     Deferred Processing Costs

     Costs related to allograft bone tissue  processing in progress are deferred
     until  processed  allograft  bone  tissue is  released  from final  quality
     assurance testing and shipped to clients.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

     Property, Plant and Equipment 

     Property,   plant  and  equipment  are  stated  at  cost  less  accumulated
     depreciation   and   amortization.   Major  renewals  and  betterments  are
     capitalized  while  maintenance  and repairs are expensed as incurred.  The
     cost of  equipment  under  capital  lease  and  leasehold  improvements  is
     amortized on the straight-line method over the shorter of the lease term or
     the  estimated  useful life of the asset.  Depreciation  is computed on the
     straight-line  method  over the  following  estimated  useful  lives of the
     assets:


          Building                                           15 years
          Machinery and equipment                            3 to 10 years
          Computer hardware and software                     5 years
          Office equipment, furniture and fixtures           5 years


     When  depreciable  assets  are  retired  or  sold,  the  cost  and  related
     accumulated  depreciation  are removed from the accounts and any  resulting
     gain or loss is reflected in operations.

     Excess of Cost Over Net Assets of Business Acquired

     The excess of cost over the net assets of business acquired ("goodwill") is
     being amortized on a straight-line basis over 15 years. It is the Company's
     policy  to  periodically  review  and  evaluate  whether  there has been an
     impairment  in the value of goodwill.  Factors  considered in the valuation
     include  current  operating  results,  trends,  prospects  and  anticipated
     undiscounted future cash flows.

     Translation of Foreign Currency

     Assets and liabilities of foreign  subsidiaries  are translated at rates of
     exchange  in effect at the close of the year.  Revenues  and  expenses  are
     translated  at  the  weighted  average  exchange  rates  during  the  year.
     Translation  gains and losses are included in other  comprehensive  income,
     which is a separate  component of  stockholders'  equity.  Foreign currency
     transaction gains and losses are included in other income.

     Concentrations of Credit Risk

     The Company  provides credit,  in the normal course of business,  to tissue
     banks and  hospitals.  The Company  maintains  an  allowance  for  doubtful
     accounts and charges actual losses to the allowance when incurred.

     The   Company   invests   the   majority   of  its  excess   cash  in  U.S.
     Government-backed securities and investment grade commercial paper of major
     U.S.  corporations.  The  Company  does not  believe  it is  exposed to any
     significant credit risk on its cash equivalents and short-term investments.

     Use of Estimates

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


3.   CHANGES IN ACCOUNTING POLICIES

     Effective  January 1, 1998,  the Company  adopted  Statement  of  Financial
     Accounting  Standards  No. 130,  "Reporting  Comprehensive  Income"  ("SFAS
     130").  SFAS  130  establishes  standards  for  reporting  and  display  of
     comprehensive  income  and  its  components  in the  financial  statements.
     Comprehensive  income  consists  of net income  and other  gains and losses
     affecting  stockholders'  equity that, under generally accepted  accounting
     principles,  are excluded from income. For the Company,  such items consist
     solely of foreign currency  translation  adjustments.  The adoption of SFAS
     130 did not have a material effect on primary financial statements, but did
     affect the  presentation  of the  accompanying  Consolidated  Statement  of
     Changes in Stockholders' Equity.

     On January 1, 1998, the Company adopted  Statement of Financial  Accounting
     Standards No. 131, "Disclosures about Segments of an Enterprise and Related
     Information" ("SFAS 131"). SFAS 131 establishes  standards for the way that
     public business  enterprises report information about operating segments in
     annual  financial  statements  and requires that those  enterprises  report
     selected  information about operating segments in interim financial reports
     issued  to  shareholders.   It  also   establishes   standards  or  related
     disclosures  about  products  and  services,  geographic  areas,  and major
     customers.  Financial statement  disclosures for prior periods are required
     to be  restated.  The  adoption  of SFAS 131 did affect the way the Company
     reports information about its operating segments.  The information for 1997
     and 1996 has been restated to conform to the 1998 presentation.

4.   RESTRUCTURING OF THE NETHERLANDS OPERATIONS

     In  October,  1996,  the  Company  announced  a  plan  to  restructure  its
     non-allograft bone tissue operations located in Leiden, The Netherlands. In
     connection   with  the   restructuring,   the  Company   discontinued   its
     PolyActive(TM)  polymer  research and development  program,  and recorded a
     pre-tax  charge to earnings  of  $1,350,000  which  included  $425,000  for
     employee termination costs, $541,000 for write-off of equipment, intangible
     assets  and  inventory,  $234,000  for costs  associated  with the  planned
     sub-leasing  of office space in Leiden on which the Company has a long-term
     lease and $150,000 for other contractual obligations.

5.   ACQUISITION

     In June, 1998, the Company acquired a 5% interest in OST Developpement S.A.
     ("OST"), for 496,662 French Francs ("FRF") or approximately $84,400. OST is
     a  processor  of bovine  bone grafts for  orthopaedic  and dental use.  The
     acquisition was accounted for on the cost method. Subsequently,  in January
     1999, the Company  acquired an additional 85% interest for FRF 8,503,338 or
     approximately  $1,510,000,  bringing its ownership to 90%. The Company also
     has the  option  to  purchase  the  remaining  10% of OST at a price  to be
     determined at the time of purchase.

     During 1998, the Company made interest bearing loans to OST aggregating FRF
     2,300,000 or $396,000 at the December 31, 1998  exchange  rate,  to support
     its capital expenditure and working capital requirements.

8.   COMMITMENTS AND CONTINGENCIES

     Service Agreements

     Osteotech is the  exclusive  processor  of allograft  bone tissue for large
     national and international  clients.  The Company provides these processing
     services pursuant to long-term service agreements.  Osteotech's  agreements
     with  its  clients  generally  provide  for  cross-indemnification  against
     liability  arising out of performance of the agreements.  Effective January
     1, 1997 the Company entered into a new ten-year  processing  agreement with
     one of its major allograft bone tissue processing clients, the American Red
     Cross Tissue Services ("ARC").  Effective April 1, 1997 the Company entered
     into a new five-year  processing agreement with its other major client, the
     Musculoskeletal Transplant Foundation ("MTF").

8.   COMMITMENTS AND CONTINGENCIES (continued)

     License and Option Agreement

     In June,  1997,  the Company  entered into an exclusive  worldwide  license
     agreement for its proprietary PolyActive(TM) polymer biomaterial technology
     and patents with IsoTis BV (formerly  Matrix Medical BV), The  Netherlands.
     Pursuant to the terms of the  agreement,  the Company  received an up front
     license payment of 500,000 Dutch Guilders ("dfl") or approximately $257,000
     in 1997 and an additional  license payment of dfl 250,000 or  approximately
     $124,000 in 1998,  which were recognized as license fee revenue.  IsoTis BV
     is  required  to make an  additional  license  payment  of dfl  250,000  or
     approximately  $133,000 at the  December  31, 1998  exchange  rate in June,
     1999.  Additionally,  IsoTis BV has an option to acquire the technology for
     dfl 4-million (approximately $2.1 million at the December 31, 1998 exchange
     rate)  commencing in the third year of the agreement and extending  through
     the sixth year of the agreement.

     Throughout the term of the agreement, which is the longer of ten years from
     the  first  commercial  sale of  product  or the life of the  patents,  the
     Company will  receive a royalty of 5% of net sales,  declining to 2% of net
     sales if the option to purchase the technology is exercised.  Further,  the
     agreement requires IsoTis BV to achieve certain milestones during the first
     three years of the  agreement.  Failure to do so will result in its loss of
     exclusive rights to the patents and technology.

     Product Liability Litigation

     The Company is a defendant in two state court product  liability actions in
     which patients claim that they have suffered  damages from the implantation
     of orthopaedic bone screws allegedly distributed by the Company. One of the
     actions  is  stayed.  Management  believes  that the suits and  claims  are
     without  merit and will continue to defend such actions  vigorously.  It is
     the Company's  position that either a device distributed by the Company was
     not implanted in the patient,  or that if the allegations in the complaints
     regarding the use of the device are assumed to be true, the device was used
     in a manner  which  was  contrary  to the use  approved  by the FDA and the
     Company's  written  warnings  concerning use.  Pursuant to its distribution
     agreement  with  the  Company,  the  manufacturer  of the  spinal  fixation
     devices,  Heinrich C. Ulrich,  KG  ("Ulrich")  has agreed to indemnify  the
     Company for all costs,  and damages  incurred by the Company in  connection
     with its distribution of products manufactured by Ulrich, except such costs
     and damages which are caused by the  Company's  gross  negligence,  willful
     misconduct  or  unauthorized  claim made by the  Company in  marketing  the
     products.  In connection with this  indemnification,  the Company  received
     $62,000 from Ulrich in 1998 and $16,000 in 1997 as reimbursement  for legal
     costs incurred.

     In July,  1998,  a  complaint  was filed  against the Company in the Second
     Judicial  District  Court,  Bernallilo  County,  New Mexico,  which alleges
     negligence,    strict    liability,    breach   of   warranty,    negligent
     misrepresentation,  fraud,  and  violation  of the New Mexico  Unfair Trade
     Practices Act arising from allegedly  defective  dental implant coating and
     coating services provided to plaintiffs by a subsidiary of the Company, Cam
     Implants BV.  Plaintiffs have demanded  unspecified  monetary  damages.  On
     August 14,  1998,  the Company  removed  this  action to the United  States
     District  Court for the  District of New Mexico.  On August 24,  1998,  the
     Company filed and served its answer,  denying any and all liability in this
     action,  and moved to dismiss five of the seven claims alleged  against it.
     On November 5, 1998, the Company moved for summary judgment in its favor on
     all of the  claims  alleged  in this  action,  on the  ground  that  all of
     plaintiffs' claims are barred by their applicable  statutes of limitations.
     To date the Court  limited  discovery in this action to matters  related to
     the statue of  limitations  issue.  The  Company  believes  that the claims
     against it are without merit and will continue to vigorously defend against
     such claims. See Note 21 "Subsequent Events."

8.   COMMITMENTS AND CONTINGENCIES (continued)

     Patent Litigation

     In January,  1998, the Company filed a patent  infringement  action against
     GenSci   Regeneration   Laboratories,   Inc.  ("GenSci  Labs")  and  GenSci
     Regeneration  Sciences,  Inc. ("GenSci  Sciences") alleging that the GenSci
     parties  violated  claims of one of the  patents  involving  the  Company's
     Grafton(R) Demineralized Bone Matrix (DBM) process. Approximately two weeks
     after  Osteotech's  filing,  GenSci  Labs filed a suit  against the Company
     alleging  patent  infringement  of two  patents  assigned to GenSci Labs in
     addition to tortious  interference  with a business  expectancy,  negligent
     interference with a prospective  economic  advantage and inducing breach of
     contract and seeking a declaratory judgment of the invalidity of two of the
     Company's patents covering  Grafton(R) DBM. In February,  1998, GenSci Labs
     amended its complaint  alleging  essentially  the same causes of action but
     adding a third patent to the allegation of patent infringement. The actions
     have been  consolidated into one lawsuit.  In September,  1998, GenSci Labs
     served an amended complaint,  which asserted, in addition to the previously
     asserted  claims,  claims  of  false  advertising  under  Federal  law.  In
     September,  1998, the Company served its answer to this amended  complaint,
     asserted  counterclaims  against  GenSci  Labs  and  served  a  third-party
     complaint  against GenSci  Sciences,  and DePuy Motech,  Inc. The Company's
     counterclaims  and third  party  complaint  accused  the GenSci  parties of
     infringing a second Company  patent,  in addition to the patent referred to
     above,  and accused the DePuy  Motech,  Inc.  and GenSci  parties of acting
     jointly  and  severally  in  infringing  on the  claims  of  both  patents.
     Discovery has  commenced and is ongoing.  The Company has and will continue
     to vigorously  defend any claims against it and prosecute the claims it has
     asserted against the GenSci and DePuy parties.

     In February,  1999, a complaint was filed against the Company in the United
     States  District Court for the Northern  District of Florida.  This action,
     which has been brought by  plaintiffs,  University of Florida  Tissue Bank,
     Inc.,  Regeneration  Technologies,  Inc.,  Sofamor Danek Group,  Inc.,  and
     Sofamor Danek L.P.,  alleges that Osteotech's  bio-d(TM)  threaded cortical
     bone  dowel  and  Endodowel  infringe  on the  claims  of U.S.  Patent  No.
     5,814,084, entitled "Diaphysical Cortical Dowel." Although monetary damages
     are sought, an amount has not been specified.  Based upon reviews conducted
     by its  outside  patent  counsel,  Osteotech  believes  that its  bio-d(TM)
     threaded  cortical  bone dowel and  Endodowel  do not  infringe  the patent
     asserted in the action. Osteotech intends to vigorously defend the action.

     Litigation  is subject to many  uncertainties  and  management is unable to
     predict the outcome of the pending  suits and claims.  It is possible  that
     the results of operations or liquidity and capital resources of the Company
     could  be  adversely  affected  by the  ultimate  outcome  of  the  pending
     litigation or as a result of the costs of  contesting  such  lawsuits.  The
     Company is unable to estimate the  potential  liability,  if any,  that may
     result from the pending litigation and,  accordingly,  no provision for any
     liability   (except  for  accrued   legal  costs)  has  been  made  in  the
     consolidated financial statements.

10.  STOCKHOLDERS' EQUITY

     Preferred Stock

     The  authorized  capital  of  the  Company  includes  5,675,595  shares  of
     Preferred  Stock,  the rights and provisions of which will be determined by
     the Board of Directors  at the time any such shares are issued,  if at all.
     No shares of  Preferred  Stock were issued or  outstanding  at December 31,
     1998 and 1997.

     Stock Options 

     The Company  has two stock  option  plans under which stock  options may be
     granted:  the  1991  Stock  Option  Plan  (the  "1991  Plan")  and the 1991
     Independent Directors Stock Option Plan (the "Directors Plan").

     The 1991 Plan, as amended,  authorizes the grant of up to 4,220,648  shares
     of the  Company's  common stock in the form of incentive  stock  options or
     non-qualified stock options to employees and consultants. Stock options may
     be  granted at prices  not less than 100% of the fair  market  value at the
     date of option  grant.  Options  generally  become  exercisable  in ratable
     installments over a four-year period,  with unexercised options expiring no
     later than ten years from the date of grant.

10. STOCKHOLDERS' EQUITY (Continued)

     The  Directors  Plan,  as  amended,  authorizes  the grant of up to 750,000
     shares of the  Company's  common stock to members of the Board of Directors
     who are not officers or employees of the Company.  Option  exercise  prices
     equal 100% of the fair market  value on the date of grant.  Options  issued
     prior to July 1, 1997 become exercisable in ratable  installments over four
     years with  unexercised  options expiring five years from the vesting date.
     Effective  July 1, 1997,  the  Directors  Plan was  amended to provide  for
     options issued to become 100%  exercisable on the first  anniversary of the
     date of grant with unexercised  options expiring ten years from the date of
     grant.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


10.  STOCKHOLDERS' EQUITY (continued)

     The Company has adopted the  "disclosure  only"  provisions of Statement of
     Financial   Accounting  Standards  No.  123,  Accounting  for  Stock  Based
     Compensation ("SFAS 123") and,  accordingly,  no compensation cost has been
     recognized in the Statements of Operations. Pro forma information regarding
     net income  (loss) and net income (loss) per share is required by SFAS 123,
     and has been  determined as if the Company  accounted for its stock options
     under the Fair Value  Method of that  Statement.  For  purposes  of the pro
     forma disclosures,  the estimated fair value of the options is amortized to
     expense over the options' vesting period. Pro forma information follows:

     ---------------------------------------------------------------------------

     The pro forma  effect on net income  (loss) for 1998,  1997 and 1996 is not
     representative  of the pro  forma  effect on net  income  in  future  years
     because,  in accordance  with FAS 123, it does not take into  consideration
     pro forma compensation expense related to grants made prior to 1995.

     The fair value for the option  grants  was  estimated  at the date of grant

     times,  issued  warrants to purchase its  Convertible  Preferred  Stock and
     Common Stock.  Warrant activity for the years ended December 31, 1996, 1997
     and 1998 is summarized as follows:

     Convertible  Preferred  Stock  warrants are  immediately  convertible  into
     Common  Stock  upon  exercise  on a share for  share  basis.  Warrants  are
     exercised through the payment of cash or under a cashless  exercise.  Under
     the cashless exercise method,  the number of shares issued upon exercise of
     such warrant is determined by  calculating  the aggregate  number of shares
     represented by the warrants using the closing price of the Company's Common
     Stock on the exercise  date,  deducting  the  aggregate  exercise  cost and
     dividing  the net  remaining  amount by the  market  value per share on the
     exercise date.

     Stock Purchase Plan

     The 1994  Employee  Stock  Purchase Plan provides for the issuance of up to
     375,000 shares of Common Stock.  Eligible  employees may purchase shares of
     the Company's  Common Stock through  payroll  deductions of 1% to 7 1/2% of
     annual  compensation.  The purchase  price for the stock is 85% of the fair
     market  value of the  stock on the last day of each  calendar  quarter.  At
     December 31, 1998, 266,883 shares were available for future offerings under
     this plan.

     Stock Repurchase Program

     In June  1998,  the  Board  of  Directors  of the  Company  authorized  the
     repurchase and retirement of up to $5,000,000 of the Company's common stock
     through open market  purchases.  During August 1998, the Company  completed
     this program and had repurchased and retired 367,500 shares of common stock
     at a cost of $4,958,000.

10.  STOCKHOLDERS' EQUITY (continued)

     Stockholder Rights Agreement

     In January, 1996, the Board of Directors of the Company unanimously adopted
     a  stockholder  rights  agreement  (the  "Rights  Agreement")  declaring  a
     dividend of one  preferred  stock  purchase  right (the  "Right")  for each
     outstanding  share of common  stock as of  February  12,  1996.  Each Right
     entitles the stockholder to purchase from the Company one  one-hundredth of
     a preferred  share at a price of $35.00 per share,  subject to  adjustment.
     The Rights will not be  exercisable  or  separable  from the common  shares
     until ten business days after a person or group acquires or tenders for 20%
     or more of the Company's  outstanding common shares  ("triggering  event").
     The Rights  Agreement also provides that,  after a triggering event occurs,
     the Rights  convert into a Right to buy common stock and entitle its holder
     to receive upon exercise that number of common shares having a market value
     of two times the exercise  price of the Right.  In the event the Company is
     acquired in a merger or other business combination transaction,  each Right
     will  entitle  its holder to receive  upon  exercise  of the Right,  at the
     Right's then current exercise price, that number of the acquiring company's
     common shares having a market value of two times the exercise  price of the
     Right.  The Company is entitled to redeem the Rights at a price of $.01 per
     Right at any  time  prior to their  becoming  exercisable,  and the  Rights
     expire on February 12, 2006.  The Rights  Agreement was adopted to maximize
     the  value  of all  stockholders'  ownership  interest  in the  Company  by
     establishing  a deterrent to abusive  takeover  tactics  sometimes  used in
     challenges for corporate control.

11. DEBT AND FINANCING ARRANGEMENTS

     The  Company  has a loan and  security  agreement  with a U.S.  bank  which
     provides for  borrowing up to $3,000,000  under a revolving  line of credit
     and $4,000,000 under an equipment line of credit.  The annual interest rate
     on revolving  loan advances is based upon the bank's prime rate whereas the
     annual  rate of  interest  on  equipment  advances is based upon the bank's
     prime rate plus a margin of .25%.  Borrowings  under the equipment  line of
     credit  are  repayable  over a 48  month  term  and are  collateralized  by
     equipment purchased with such borrowings. The Company is required under the
     agreement to maintain  certain  financial ratios and meet certain net worth
     and indebtedness  tests. An annual commitment fee of .25% is payable on the
     unused  portion of the revolving  line of credit.  At December 31, 1998 and
     1997,  $172,000  and  $709,000,  respectively,  was  outstanding  under the
     equipment  line of credit and there were no borrowings  under the revolving
     line of credit.

     In December,  1998, the Company  received a commitment  from the bank for a
     new credit  facility  which will  replace the current  facilities.  The new
     credit  facility will include a $5,000,000  revolving  line of credit and a
     $21,500,000  building  mortgage loan and equipment line of credit which the
     Company  will  use to fund the  planned  construction  of a new  processing
     facility. Consummation of the new credit facility is subject to negotiation
     and execution of a definitive agreement.

     The  Company  has a line of credit  with a Dutch  bank which  provides  for
     borrowing up to dfl 5,000,000, or approximately  $2,659,000 at the December
     31, 1998 exchange rate.  Borrowings under this credit line bear interest at
     the bank's prime rate plus a margin of 2.25%.  Under certain  circumstances
     the  Company may elect to utilize a rate based on the  Amsterdam  Interbank
     Offered  Rate  (AIBOR)  plus a margin of .75%.  Analysis  of the  Company's
     financial  position and anticipated cash flow indicated that it most likely
     would not be  necessary  to utilize a  significant  portion of this line of
     credit in 1998 and,  therefore,  the Company  agreed with the bank to limit
     its borrowings,  if any, to be no more than dfl 3,000,000, or approximately
     $1,595,000 at the December 31, 1998 exchange rate. At December 31, 1998 and
     1997, there were no borrowings under this line of credit.

17.  OPERATING SEGMENTS

     Effective January 1, 1998, the Company adopted SFAS 131 (see Note 3). Prior
     year  information has been restated to present the Company's two reportable
     business segments:  the Grafton(R) DBM segment and Base Tissue segment. The
     Grafton(R) DBM segment  engages in the processing and marketing  Grafton(R)
     DBM.  Grafton(R) DBM is processed using the Company's advanced  proprietary
     demineralization process. The Base Tissue segment engages in the processing
     of  primarily  weight-bearing  mineralized  allograft  bone tissue which is
     generally marketed by the Company's clients.

     The accounting  policies of the  reportable  segments are the same as those
     described in the Summary of Significant  Accounting  Policies.  The Company
     evaluates  the  performance  of its  operating  segments  based on  revenue
     performance and operating results. The Company does not produce information
     about  assets  for  its  operating  segments,   and  accordingly  no  asset
     information is presented in the table below. All corporate related expenses
     are allocated to operating  segments and  geographic  areas in  determining
     operating income (loss) of the respective segments.

     Summarized  financial  information   concerning  the  Company's  reportable
     segments  is shown in the  following  table.  The "Other"  column  includes
     information for other business units below the quantitative thresholds. The
     Company's  other  business  units engage in providing  ceramic and titanium
     plasma  spray  coating   services  to   orthopaedic   and  dental   implant
     manufacturers  and marketing  and  distributing  non-allograft  bone tissue
     spinal implant products.

     Osteotech's Performance Bonus Plan is designed to focus attention on and
     motivate the achievement of important Company and individual goals.

     This booklet explains how the Performance Bonus Plan works. It will answer
     many of your questions about the mechanics of the Plan and provide the
     information you need to understand how performance affects your earnings.

     If, after reading the booklet, you have questions about the plan, contact
     the Director of Human Resources at (732) 544-6225.

ELIGIBILITY

     Position responsibilities and the ability to directly influence Company
     performance are the key criteria used to determine Performance Bonus Plan
     participation.

     Eligibility to participate in the Performance Bonus Plan is extended to
     Senior Managers in salary grades 16 and 17. Eligibility for an award is
     based on individual performance rating and the Company's PBT results.

PLAN EFFECTIVE 
DATE

     The plan is effective January 1, 1998. This plan supersedes all prior
     programs and previously agreed to terms for incentive compensation.

PLAN OBJECTIVES

     The Performance Bonus Plan rewards the achievement of pre-established
     annual OTI and individual goals by providing the opportunity for a cash
     award when the goals are achieved.

     Osteotech's Performance Bonus Plan is designed to:

     1.   Focus attention on the achievement of annual business results.

     2.   Support the objective-setting processes--awards are tied to the
          accomplishment of OTI business objectives.

     3.   Reward significant contributions to Osteotech's success. 

     4.   Attract and retain high-performing Senior Managers.

OTI AND INDIVIDUAL 
PERFORMANCE 
DETERMINE ACTUAL 
AWARD

     The Performance Bonus Plan is based on achieving annual OTI and individual
     performance objectives.

     o    OTI performance is measured by OTI profit before taxes (PBT). PBT
          goals are set each year in the annual planning process.

     o    Individual objectives are established in conjunction with OTI's annual
          performance planning process.

EACH PARTICIPANT
HAS A TARGET 
INCENTIVE
OPPORTUNITY

     As a participant in the Plan, you have a target award opportunity equal to
     a percentage of your annual salary. The target award opportunity is the
     amount that would be paid if OTI and individual results meet
     pre-established performance goals / standards.

     The target opportunity differs from the actual payout.

     o    The opportunity is the amount available for meeting all performance
          goals.

     o    The actual payout is the amount paid to you based on the level of
          performance achieved. The payout may be higher, lower, or equal to
          your target opportunity.

Target Opportunity Is a 
Percent of Salary

     Your target incentive opportunity is calculated as a percentage of your
     salary. For Senior Managers in Grades 16 and 17, the target incentive
     opportunity will range from 10% to 20%.

     For example, if your salary is $90,000, and your target incentive
     opportunity percentage is 15%, your target incentive opportunity would be
     $13,500 ($90,000 x .15 = $13,500).

The Target Percentage 
Is Based on Position
Criteria and Individual 
Performance History

     In surveying benchmark positions, we found our pay mix was skewed towards
     base pay and, as a result, was less competitive in the incentive area. Our
     new plan has a stronger focus on incentives.

     Your exact target percentage (ranging from 10% to 20%) is based on five
     criteria. The criteria are shown below. Three of the criteria are
     influenced by your position; two are influenced by your performance.
     Another element considered is competitive pay mix. All targets are reviewed
     to ensure they are appropriate vis-a-vis competitive incentive
     opportunities.

     Each of the factors is assessed along a continuum. The assessment
     determines where a position should be rated with respect to each criterion.
     This assessment helps to determine a participant's target incentive
     percentage. This target incentive percentage may change from year to year
     based on the continual evaluation of factors.

- --------------------------------------------------------------------------------


     Each year, your manager immediate manager will recommend a specific target
     opportunity percentage based on a careful assessment of your position and
     your performance. The recommendation is a judgment by the manager: there is
     no formula to determine the outcome. Once this step is complete, your
     immediate manager will forward the work sheet to Human Resources. The
     President and HR Director will review the worksheet's proposed incentive
     target to assure consistency and balance. Final approval will come from the
     President / CEO.

     An example of an assessment and judgment is shown below.

OPPORTUNITY FOR 
PAYOUT BEYOND
TARGET
OPPORTUNITY

     If Corporate performance exceeds expectations, your actual payout can
     exceed the target opportunity. In fact, your actual payout can reach more
     than one-and-one-quarter (1.25+) times your target opportunity based on
     actual results achieved.

     Conversely, your actual payout can be less than the target opportunity if
     OTI and individual performance fall below expectations. If performance
     fails to meet minimum expectations, it is possible that no payout will be
     provided. (See explanation of "Performance Gate" below.)

     The total payout potential is explained in the Award Components section.


PERFORMANCE GATE

     The plan has a performance "gate," which specifies minimal acceptable
     performance that must be achieved before any award will be paid. The
     performance gate is as follows:

     o    Your individual performance rating cannot be "Unsatisfactory" to
          qualify for an annual incentive payout.


     The gate applies to the total award. For example, if individual performance
     were rated "Unsatisfactory" both the OTI and individual components are
     forfeited.

Award Components
============================================
- --------------------------------------------------------------------------------


OTI COMPONENT

     OTI performance will be measured by OTI's profit before taxes (PBT).

     In determining results, non-recurring losses and/or windfalls will be
     excluded from the calculations.

     PBT was chosen as the OTI financial measure because plan participants can
     directly influence its results. The goal will be established each year in
     conjunction with Osteotech's annual planning process.


RANGE OF EXPECTED 
PERFORMANCE

     At the beginning of each year, a range of performance will be established
     for PBT. This range will be anchored by three levels of performance:

     o    Goal, or planned level of performance. This represents 100% of goal
          achievement.

     o    Threshold, or minimum level of performance. Some amount will be paid
          for performance at threshold. However, if PBT fails to reach the
          threshold, no award will be paid for OTI performance.

     o    Maximum level of performance. If PBT reaches or exceeds maximum, the
          highest possible award for the OTI component will be paid.

     As shown in the chart, to achieve your target incentive opportunity for OTI
     performance, PBT results must reach 100% of budget.

Award Components
============================================
- --------------------------------------------------------------------------------


INDIVIDUAL 
COMPONENT

     Twenty-five percent of your target award opportunity will be based on your
     individual performance.

     At the beginning of each year, you and your Manager will establish
     individual performance objectives in conjunction with OTI's performance
     planning process.

     At the end of the year, your Manager will assess your results against these
     objectives and determine an overall performance rating for your individual
     performance. Your results and your performance rating will determine your
     individual payout.

     In the chart below, the award payout percentages are guidelines. Managers
     will use their judgment to determine the amount of the award within the
     ranges shown, based on the results achieved. Managers will also be able to
     adjust for the impact of critical, unplanned achievements over the year.

EARNINGS EXAMPLE

     The following hypothetical examples demonstrate the earnings opportunities
     under the plan for the same Senior Manager under two different performance
     scenarios.

Assume:

     o    Senior Manager has a base salary of $90,000 and a target award of 15%,
          or $13,500.

     o    The award calculation is as follows.

Administrative Details
============================================
- --------------------------------------------------------------------------------


APPROVAL OF
AWARDS

     The Manager to whom a participant reports will recommend individual awards.
     The final approval comes from the President / CEO of OTI.

ELIGIBILITY FOR
PAYMENT

     Eligibility to participate in the Performance Bonus Plan is extended to
     Managers and Directors who have been functioning in a Grade 16 or 17 for at
     least three months during the plan year. Awards will be prorated based on
     months of eligibility. Voluntary resignation, prior to the payment of
     Performance Bonus, precludes receipt of any award.

     Eligible participants must be actively employed to receive the Performance
     Bonus. However, if a participant retires, dies, or becomes permanently
     disabled during the plan year, a pro-rata award will be paid based on the
     time worked during the year. This award may be granted at 100% at the
     discretion of the President and CEO.

     Individuals who are promoted or hired into grade 16 or 17 in the last
     quarter of the year will not be eligible for an award that year.
     Eligibility for these individuals will commence with the subsequent plan
     year.

     Terminations and resignations will cause an individual to be ineligible for
     any payment not already received. In the event of an involuntary
     termination without cause (layoff), a pro-rated payout may be made.

PLAN CHANGES

     Each year, management reserves the right to reassess the terms and
     conditions of the plan and revise the plan design and components.


AWARD
DETERMINATION

     Initial payments will be made in early to mid-December. These payments will
     equal 95% of the anticipated payout based on the Company's Business Results
     (PBT). Final awards will be determined and paid, as early as possible,
     following the year-end close and audit.

Corporation in the performance of his duties hereunder upon  presentation by the
Employee to the Corporation of appropriate vouchers.

     6. Involuntary Termination. (a) If Employee is incapacitated or disabled by
accident,  sickness or  otherwise  so as to render him  mentally  or  physically
incapable of performing the services  required to be performed by him under this
Agreement for a period of 90 consecutive  days or longer,  or for 90 days during
any ten-month period (such condition being herein referred to as  "Disability"),
the Corporation  may, at that time or any time thereafter,  at its option,  with
the  approval  of a  majority  of the  Board of  Directors  of the  Corporation,
terminate  the  employment of Employee  under this  Agreement  immediately  upon
giving him notice to that effect  (such  termination,  as well as a  termination
under   Section  6(b)  hereof,   being   hereinafter   called  an   "Involuntary
Termination"). Until the Corporation shall have terminated Employee's employment
hereunder  in  accordance  with the  foregoing,  Employee  shall be  entitled to
receive  his   compensation,   notwithstanding   any  such  physical  or  mental
disability.

the Employee hereunder and the Term of Employment at any time during the Term of

as amended from time to time.

     8. Termination  Without Cause. The Corporation may terminate the employment
of the Employee hereunder and the Term of Employment at any time without "cause"
(such termination being hereinafter called a "Termination Without Cause").  Upon
a Termination  without Cause during the Term of  Employment,  Employee  shall be
entitled to receive  his Base  Salary for twelve  (12) months or until  Employee
obtains  comparable  employment,  whichever  



                                      E-17
<PAGE>

occurs  sooner plus all earned but unpaid bonus at the time of  termination.  In
addition,  upon a Termination  Without Cause at any time, the Corporation  shall
continue to pay the  Employee's  family  medical  insurance  premiums  under the
Corporation's medical insurance plan and other benefits (including  outplacement
benefits)  provided  in Section  5.1(c) for twelve (12)  months  following  such
termination or until Employee obtains  comparable  employment,  whichever occurs
sooner.

     9. Voluntary Termination. Any termination of the employment of the Employee
hereunder  otherwise  then  as  a  result  of  an  Involuntary  Termination,   a
Termination  For Cause or a  Termination  Without  Cause shall be deemed to be a
"Voluntary Termination". A Voluntary Termination shall be deemed to be effective
immediately upon such termination.

     10. Effect of Termination of Employment.

     (a) Upon the termination of the Employee's employment hereunder pursuant to
a Voluntary  Termination,  Involuntary  Termination or a Termination  For Cause,
neither the Employee nor his beneficiary or estate shall have any further rights
or claims against the Corporation under this Agreement except to receive:

          (i) the unpaid  portion  of the Base  Salary  provided  for in Section
     5.1(a),  computed on a pro rata basis to the date of termination,  plus any
     earned but unpaid bonus with respect to the prior year;

          (ii)  reimbursement  for any expenses for which the Employee shall not
     have theretofore been reimbursed as provided in Section 5.1(d);

                           CHANGE IN CONTROL AGREEMENT


     AGREEMENT  by and between  Osteotech,  Inc.,  a Delaware  corporation  (the
"Company"),  and  Richard  Russo (the  "Executive"),  dated as of the 8th day of
September, 1997.

     The Board of Directors of the Company (the "Board") has determined  that it
is in the best interests of the Company and its  stockholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility,  threat or occurrence of a Change in Control (as defined in Section
1(e)) of the  Company.  The Board  believes it is  imperative  to  diminish  the
distraction of the Executive by virtue of the personal  uncertainties  and risks
created  by a pending  or  threatened  Change in Control  and to  encourage  the
Executive's  full attention and  dedication to the Company  currently and in the
event of any  threatened  or  pending  Change in  Control,  and to  provide  the
Executive with  compensation and benefits  arrangements upon a Change in Control
which ensure that the  compensation  and benefits  expectations of the Executive
will be satisfied and that such  compensation  and benefits are competitive with
those of other corporations. Therefore, in order to accomplish these objectives,
the Board has caused the Company to enter into this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          For purposes of this Agreement:

          (a) An  "Affiliate"  means  any  member of the same  affiliated  group
     (within the meaning of Section 1504 of the  Internal  Revenue Code of 1986,
     as amended (the "Code"),determined without regard to Section 1504(b) of the
     Code), that includes the Company.

          (b) The  Executive's  "Base  Period  Compensation"  is (i) the average
     annual  "compensation" (as defined below) which was includible in his gross
     income for his base period  (i.e.,  his most recent five  taxable  years or
     such lesser  number of taxable years or portions  thereof  during which the
     Executive  performed services for the Company ending before the date of the
     Change in Control);  and (ii) if Executive's  base period  includes a short
     taxable  year or less than all of a  taxable  year,  compensation  for such
     short or incomplete  taxable year shall be annualized  for the base period.
     (In annualizing compensation, the frequency with which payments are



                                      E-24
<PAGE>

     expected  to be made over an annual  period  shall be taken  into  account.
     Thus,  any amount of  compensation  for such a short or incomplete  taxable
     year that  represents  a payment  that would not be made more than once per
     year shall not be annualized). For purposes of this definition, Executive's
     "compensation" is the compensation  which was payable to him by the Company
     or an Affiliate, determined without regard to the following Sections of the
     Code: 125 (cafeteria  plans),  402(a)(8)  (cash or deferred  arrangements),
     402(h)(1)(B) (elective contributions to simplified employee pensions), and,
     in the case of employer  contributions  made pursuant to a salary reduction
     agreement, 403(b) (tax sheltered annuities).

          (c) The  "Commencement  Date"  shall  mean the first  date  during the
     Change in  Control  Period (as  defined  in Section  1(d)) that a Change in
     Control (as defined in Section 1(e)) occurs.

          (d) The "Change in Control Period" shall mean the period commencing on
     the date  hereof and ending on the third  anniversary  of the date  hereof;
     provided,  however,  that  commencing on the first  anniversary of the date
     hereof,  and on each successive annual anniversary of the date hereof (such
     date and each annual anniversary  thereof shall be hereinafter  referred to
     as the "Renewal Date"), the Change in Control Period shall be automatically
     extended so as to terminate  three years from such Renewal Date,  unless at
     least  sixty (60) days prior to the  Renewal  Date the  Company  shall give
     notice to the Executive  that the Change in Control  Period shall not be so
     extended.

          (e) "Change in Control" shall mean:

               (i) a "Board Change" which, for purposes of this Agreement, shall
          have occurred if a majority of the seats (not  counting  vacant seats)
          on the  Company's  Board were to be occupied by  individuals  who were
          neither (A) nominated by a majority of the Incumbent Directors nor (B)
          appointed by  directors so  nominated.  An  "Incumbent  Director" is a
          member of the Board who has been either (A) nominated by a majority of
          the  directors  of the  Company  then in  office or (B)  appointed  by
          directors so nominated,  but  excluding,  for this  purpose,  any such
          individual  whose  initial  assumption of office occurs as a result of
          either an actual or threatened  election contest (as such term is used
          in Rule 14a-11 of  Regulation  14A  promulgated  under the  Securities
          Exchange Act of 1934, as amended (the "Exchange Act")) or other


                                      E-25
<PAGE>

          actual or  threatened  solicitation  of proxies or  consents  by or on
          behalf of a Person other than the Board; or

               (ii) the acquisition by any  individual,  entity or group (within
          the meaning of Section  13(d)(3) or 14(d)(2) of the  Exchange  Act) (a
          "Person") of  beneficial  ownership  (within the meaning of Rule 13d-3
          promulgated  under  the  Exchange  Act)  of a  majority  of  the  then
          outstanding voting securities of the Company (the "Outstanding Company
          Voting   Securities");   provided,   however,   that   the   following
          acquisitions  shall  not  constitute  a  Change  in  Control:  (A) any
          acquisition  by the Company,  or (B) any  acquisition  by any employee
          benefit plan (or related trust) sponsored or maintained by the Company
          or any  corporation  controlled  by the  Company,  or (C)  any  public
          offering,  private  placement or other  issuance by the Company of its
          voting securities; or

               (iii) a merger  or  consolidation  of the  Company  with  another
          entity in which neither the Company nor a corporation  that,  prior to
          the merger or consolidation, was a subsidiary of the Company, shall be
          the surviving entity; or

               (iv) a merger or consolidation of the Company following which (A)
          the  Company  or  a   corporation   that,   prior  to  the  merger  or
          consolidation,  was a subsidiary of the Company shall be the surviving
          entity and (B) a majority of the Outstanding Company Voting Securities
          is owned by a Person or Persons who were not beneficial owners (within
          the meaning of Section  13(d)(3) or 14(d)(2) of the Exchange Act) of a
          majority of the  Outstanding  Company  Voting  Securities  immediately
          prior to such merger or consolidation; or

               (v) a voluntary or involuntary liquidation of the Company; or

               (vi) a sale or  disposition by the Company of at least 80% of its
          assets in a single transaction or a series of transactions (other than
          a sale or  disposition  of assets to a subsidiary  of the Company in a
          transaction  not  involving a Change in Control or a change in control
          of such subsidiary).

          Section  2(a)  hereof  and  (B)  the  Executive's  services  shall  be
          performed at the location where the Executive was employed immediately
          preceding   the   Commencement   Date  or  any  office  which  is  the
          headquarters  of the Company and is less than  fifteen (15) miles from
          such location.

               (ii) During the Employment  Period,  and excluding any periods of
          vacation  and sick  leave to which  the  Executive  is  entitled,  the
          Executive agrees to devote reasonable attention and time during normal
          business  hours to the business and affairs of the Company and, to the
          extent  necessary to discharge  the  responsibilities  assigned to the
          Executive hereunder, to use the Executive's reasonable best efforts to
          perform faithfully and efficiently such  responsibilities.  During the
          Employment  Period it shall not be a violation of this  Agreement  for
          the Executive to (A) serve on corporate, civic or charitable boards or
          committees,  (B) deliver  lectures,  fulfill  speaking  engagements or
          teach  at   educational   institutions,   and  (C)   manage   personal
          investments,  so long as such  activities  do not  interfere  with the
          performance of the Executive's  responsibilities as an employee of the
          Company in accordance with this Agreement.

          (c) Compensation.

               (i) Base Salary.  During the  Employment  Period,  the  Executive
          shall  receive an annual  base  salary  ("Annual  Base  Salary") in an
          amount at least equal to that which he was receiving immediately prior
          to the Change in Control.

               (ii) Incentive, Savings Retirement and Stock Option Plans. During
          the Employment  Period, the Executive shall be entitled to participate
          in  all  incentive,   savings,  retirement  and  stock  option  plans,
          practices,  policies and programs  applicable  generally to other peer
          executives  of  the  Company,  but  in  no  event  shall  such  plans,
          practices,   policies  and  programs   provide  the   Executive   with
          opportunities  and benefits  less  favorable  than those in effect and
          applicable  to the  Executive  immediately  preceding  the  Change  in
          Control.

               (iii) Benefit Plans.  During the Employment Period, the Executive
          and/or the Executive's  family,  as the case may be, shall be eligible
          for  participation  in and shall  receive all benefits  under  welfare
          benefit  plans,  practices,  policies  and  programs  provided  by the
          Company (including, without limitation, medical, prescription, dental,
          disability, salary continuance,  employee life, group life, accidental
          death and travel accident  insurance plans and programs) to the extent
          applicable  generally to other peer executives of the Company,  but in
          no event shall such plans,  practices,  policies and programs  provide
          the Executive  with benefits which are less favorable than such plans,
          practices,  policies  and  programs  in effect and  applicable  to the
          Executive immediately preceding the Change in Control.

               (iv) Expenses.  During the Employment Period, the Executive shall
          be  entitled  to  receive  prompt  reimbursement  for  all  reasonable
          employment  related  expenses  incurred by the Executive in accordance
          with the policies, practices and procedures of the Company which shall
          not be less favorable than those in effect  immediately  preceding the
          Change in Control.

               (v) Office and Support Staff.  During the Employment  Period, the
          Executive shall be entitled to an office or offices of a size and with
          furnishings,   and  to  exclusive   personal   secretarial  and  other
          assistance, which shall be at least equal to that provided to the



                                      E-28
<PAGE>

          Executive by the Company immediately preceding the Change in Control.

               (vi) Vacation.  During the Employment  Period  Executive shall be
          entitled  to paid  vacations  at  least  equal  to that to  which  the
          Executive was entitled immediately preceding the Change in Control.

               (vii)  Options.  Upon a Change in Control all options to purchase
          shares  of  the  Company's   Common  Stock  held  by  Executive   (the
          "Options"),  whether or not vested,  shall vest and become exercisable
          in accordance with their terms immediately prior to the effective date
          of such Change in Control (and Executive will be provided a reasonable
          opportunity  to exercise such Options prior to such  effective  date),
          notwithstanding  anything  to the  contrary  contained  in the  option
          certificates  or any plan  covering  the  Options  (collectively,  the
          "Plan").  Upon a Change in Control all Options held by Executive shall
          be exercisable in accordance  with their terms for such  securities or
          property to which  Executive  would have been  entitled had  Executive
          exercised   such   Options   prior   to  such   Change   in   Control,
          notwithstanding  anything  to  the  contrary  contained  in  any  Plan
          covering  such Options.  Upon a Change in Control  pursuant to Section
          1(e)(iii) or 1(e)(v),  all Options held by  Executive,  whether or not
          vested,  shall  terminate as of the  effective  date of such Change in
          Control  to  the  extent  not  previously  exercised,   provided  that
          Executive  shall have been provided with a reasonable  opportunity  to
          exercise such options prior to such  effective  date,  notwithstanding
          anything to the contrary  contained in the Plan covering such Options.
          Notwithstanding  the foregoing,  the terms of the Option Agreement for
          the option to purchase  48,029  shares of Common Stock  granted to the
          Executive on July 31, 1997 and not the terms of this  Agreement  shall
          govern  with  respect  to such  options  in the  event of a Change  in
          Control.

     3. Termination of Employment.

          (a) Death or Disability.  The Executive's  employment  shall terminate
     automatically  upon the Executive's death during the Employment  Period. If
     the Company  determines in good faith that the  Disability of the Executive
     has occurred  during the Employment  Period  (pursuant to the definition of
     Disability set forth below),



                                      E-29
<PAGE>

     it may give to the Executive written notice in accordance with Section 3(d)
     of its intention to terminate the  Executive's  employment.  In such event,
     the Executive's  employment  with the Company shall terminate  effective on
     the 30th day after receipt of such notice by the Executive (the "Disability
     Effective  Date"),  provided  that,  within the thirty (30) days after such
     receipt, the Executive shall not have returned to full-time  performance of
     the Executive's duties. For purposes of this Agreement,  "Disability" shall
     mean  a  physical  or  mental  condition  which  prohibits  Executive  from
     performing  his duties  hereunder for a continuous  six (6) month period or
     for a total of six (6) months during any eighteen (18) month period.

          (b)  Just  Cause.  Executive's  employment  may be  terminated  by the
     Company for Just Cause. For purposes hereof, "Just Cause" shall mean:

               (i) the  commission  by  Executive  of a willful  act of material
          fraud in the performance of his duties on behalf of the Company; or

               (ii) the  conviction of Executive  for  commission of a felony in
          connection  with  the  performance  of his  duties  on  behalf  of the
          Company.

          Prior to  termination  for Just  Cause,  the Board shall by a majority
     vote  have  declared  that  Executive's   termination  is  for  Just  Cause
     specifically stating the basis for such determination.

          (c) Good Reason.  Executive's  employment during the Employment Period
     may be terminated by Executive with Good Reason. For purposes hereof, "Good
     Reason" shall mean:

               (i) the  assignment to Executive of any duties of lesser  status,
          dignity and character than his duties  immediately prior to the Change
          in Control or a  substantial  reduction in the nature or status of his
          responsibilities  from those in effect immediately prior to the Change
          in Control;

               (ii) any failure by the Company to comply with the  provisions of
          Section 2(c);

               (iii)  relocation of  Executive's  office to a location  which is
          more than  fifteen  (15) miles from the  location  in which  Executive
          principally worked for the Company



                                      E-30
<PAGE>

          immediately  prior to the Change in Control;  or his being required by
          the Company in order to perform duties of substantially  equal status,
          dignity and character to those duties he performed  immediately  prior
          to the  Change in  Control to travel on the  Company's  business  to a
          substantially  greater  extent than is  consistent  with his  business
          travel obligations immediately prior to a Change in Control;

               (iv) the  failure by the  Company to comply  with  Section  7(a),
          provided  that the  successor  has received at least twenty (20) days'
          prior  written  notice  from  the  Company  or  the  Executive  of the
          requirements of Section 7(a); or,

               (v) the voluntary  termination by the Executive for any reason at
          any time  after  the  180th  day  immediately  following  a Change  in
          Control.

          For purposes of this  Sections  3(c) any good faith  determination  of
     "Good  Reason"  made by the  Executive  shall in all  cases be  conclusive;
     provided,  however, that for purposes of Sections 3(c)(i),  (ii), (iii) and
     (iv),  Executive  shall have given the Company prior written notice thereof
     and not less than twenty (20) days to cure such "Good Reason".

          (d) Notice of  Termination.  Any  termination  by the Company for Just
     Cause or by the Executive for Good Reason shall be  communicated  by Notice
     of Termination  to the other party hereby given in accordance  with Section
     8. For  purposes  of this  Agreement,  a "Notice  of  Termination"  means a
     written  notice which (i) indicates the specific  termination  provision in
     this Agreement  relied upon, (ii) to the extent  applicable,  sets forth in
     reasonable  detail the facts and  circumstances  claimed to provide a basis
     for  termination  of the  Executive's  employment  under the  provision  so
     indicated and (iii)  specifies the Date of  Termination  (as defined below)
     (which  date  shall be not more than  thirty  (30) days after the giving of
     such  notice).  The failure by the Executive or the Company to set forth in
     the Notice of Termination any fact or circumstance  which  contributes to a
     showing  of Good  Reason  or Just  Cause  shall  not waive any right of the
     Executive or the Company hereunder or preclude the Executive or the Company
     from asserting such fact or  circumstance  in enforcing the  Executive's or
     the Company's rights hereunder.



                                      E-31
<PAGE>

          (e) Date of  Termination.  "Date of  Termination"  means  the date the
     Company or the Executive specifies as the date of termination in the Notice
     of Termination or if the Executive's  employment is terminated by reason of
     death or Disability,  the Date of Termination shall be the date of death of
     the Executive or the Disability Effective Date, as the case may be.

     4. Obligations of Company upon Termination.

          (a)  Termination by Company for Just Cause. If at any time on or prior
     to  the  180th  day  following  the  Commencement   Date,  the  Executive's
     employment  shall  be  terminated  by the  Company  for Just  Cause,  then,
     Executive  shall  receive  all  then  accrued  pay,   benefits,   executive
     compensation and fringe benefits,  including (but not limited to), pro rata
     bonus and incentive plan earnings through the Date of Termination, plus the
     amount of any compensation  previously  deferred by the Executive,  in each
     case to the extent theretofore  unpaid. The foregoing payments and benefits
     shall be deemed  compensation  payable  for the duties to be  performed  by
     Executive  pursuant  to  Section  2. If at any time  after  the  180th  day
     following  the  Commencement  Date,  the  Executive's  employment  shall be
     terminated  by the  Company  for Just Cause,  then the  Executive  shall be
     entitled to the payment and benefits described in Section 4(b), below.

          (b)  Termination  by  Executive  for Good Reason;  Termination  by the
     Company at Any Time Other Than For Just Cause;  Termination  by the Company
     For Just  Cause  After the  180th  Day  Following  the  Commencement  Date;
     Termination  Upon Expiration of the Employment  Period.  If (i) the Company
     shall terminate the Executive's  employment at any time other than for Just
     Cause; or, (ii) the Company shall terminate Executive's employment for Just
     Cause after the 180th day following the  Commencement  Date;  or, (iii) the
     Executive  shall  terminate his employment at any time for Good Reason;  or
     (iv) the  Executive's  employment with the Company shall terminate upon the
     expiration  of the  Employment  Period,  in  addition  to any  other  sums,
     benefits or compensation otherwise payable to him by the Company:

               (i) Executive  shall  receive,  no later than the next pay period
          following  the Date of  Termination,  all then accrued pay,  benefits,
          executive compensation and fringe benefits, including (but not limited
          to), his pro rata bonus and incentive  plan earnings  accrued  through
          the Date of Termination, plus the amount of any compensation




                                      E-32
<PAGE>

          previously  deferred  by the  Executive,  in each  case to the  extent
          theretofore unpaid;

               (ii) Executive shall receive, at the Company's expense,  medical,
          health and disability benefits which are substantially  similar to the
          benefits the Company is providing him immediately preceding the Change
          in  Control  for  a  period  of  thirty-six  (36)  months  immediately
          following the Date of Termination;

               (iii)  Executive shall receive an amount equal to one dollar less
          than  the sum of (A) 300% of his Base  Period  Compensation,  plus (B)
          interest  thereon for the period  beginning on the  Commencement  Date
          through the date or dates of  payment,  at a rate equal to 120% of the
          applicable Federal rate, determined under Section 1274(d) of the Code,
          compounded semiannually.

               (iv) Except in the case of a termination  by the Company for Just
          Cause or a voluntary  termination by the Executive in accordance  with
          Section  3(c)(v),  Executive  shall  receive  the  balance of all pay,
          benefits, compensation and fringe benefits, including (but not limited
          to),  pro rata  salary,  bonus and  incentive  plan  earnings  payable
          through the remainder of the Employment Period; and,

               (v) Except in the case of a  termination  by the Company for Just
          Cause or a voluntary  termination by the Executive in accordance  with
          Section 3(c)(v),  Executive shall be entitled to a private office with
          furnishings  and  secretarial  and other  reasonable  services for the
          period  beginning with the Date of Termination and ending on the first
          anniversary thereof.

          The  foregoing  payments  and  benefits  shall be deemed  compensation
     payable  for duties to be  performed  by  Executive  pursuant to Section 2.
     Except  for the  payments  and  benefits  described  in  Sections  4(b)(i),
     4(b)(ii),  and 4(b)(v) the sums due  pursuant to this Section 4(b) shall be
     paid in one  lump-sum  payable no later than sixty (60) days after the Date
     of  Termination.  All sums of money  due  hereunder  shall  be  subject  to
     appropriate withholding and statutory requirements.  Executive shall not be
     required to mitigate the amount of any payment provided for in this Section
     4(b) by seeking other  employment or  otherwise.  Notwithstanding  anything
     stated in this Section 4(b) to the


                                      E-33
<PAGE>

     contrary,  Company shall not be required to provide medical,  health and/or
     disability  benefits to the extent such benefits would  duplicate  benefits
     received  by  Executive  in  connection  with his  employment  with any new
     employer.

          The determination of the amounts and benefits payable to the Executive
     pursuant  to  Sections  4(b)(i),  4(b)(iii)  and  4(b)(iv)  (the  "Combined
     Amount") shall first be made by the Company in good faith,  and the Company
     shall notify the Executive of the Combined Amount as soon as possible after
     the Date of  Termination,  but in no event later than  forty-five (45) days
     prior to the  payment  date of the sums due  under  Section  4(b)(iii)  and
     4(b)(iv).  If the Executive  disagrees with the Company's  determination of
     the  Combined  Amount,  then  within  ten (10) days  after the date of such
     notification  to the Executive,  the Executive  shall notify the Company of
     such disagreement,  the extent of such disagreement (the "Disputed Amount")
     and the amount that is undisputed (the "Undisputed Amount"). The Undisputed
     Amount shall be paid in one lump-sum payable sixty (60) days after the Date
     of   Termination,   subject  to  appropriate   withholding   and  statutory
     requirements.  If the Company disagrees with the Executive's  determination
     of the  Combined  Amount,  then within ten (10) days after the date of such
     notification  to the Company,  it shall  furnish  Executive  with a written
     appraisal of the Combined  Amounts (the "First  Appraisal")  prepared by an
     independent  certified public accountant  regularly employed by the Company
     (the "First Appraiser"). If Executive disagrees with the amounts determined
     pursuant to the First Appraisal,  then within ten (10) days after notice of
     the First Appraisal,  he shall furnish the Company with a written appraisal
     of the Combined Amount (the "Second Appraisal")  prepared by an independent
     certified public accountant (the "Second Appraiser").  Within ten (10) days
     after notice of the Second  Appraisal,  the First  Appraiser and the Second
     Appraiser  shall  meet and  shall  endeavor,  within  ten (10) days of such
     meeting,  to agree upon the Combined  Amount and notify the Company and the
     Executive thereof; provided, however, that if they are unable to agree upon
     the Combined  Amount,  then,  within (10) days of such meeting,  they shall
     engage an independent  certified public accountant (the "Third  Appraiser")
     and notify the Company and the  Executive of their  engagement of the Third
     Appraiser,  whose  determination of the Combined  Amount,  if any, shall be
     final and conclusive  and binding on the Company and the Executive.  Within
     ten (10) days after notice of such  engagement,  the Third  Appraiser shall
     determine  the Combined  Amount and notify the Company and the Executive of
     his determination  (the "Final Amount").  Except for the benefits described
     in Sections 4(b)(ii) and 4(b)(v), the Final Amount, as



                                      E-34
<PAGE>

     adjusted by any prior payment of the Undisputed  Amount or any payment made
     pursuant to Section  4(b)(i),  shall be paid in one lump-sum payable on the
     later of (i) sixty (60) days after the Date of Termination,  or (ii) twenty
     (20) days after notification of the Final Amount, in either case subject to
     appropriate withholding and statutory requirements; provided, however, that
     notwithstanding  the  foregoing,  the  Executive  shall  have the option to
     decline the benefits  described in Section  4(b)(ii) no later than ten (10)
     days prior to such payment date.

          (c)  Disability or Death.  If the  Executive's  employment  during the
     Employment  Period is terminated  at any time by reason of the  Executive's
     Disability  or  death,  this  Agreement  shall  terminate  without  further
     obligations to the Executive,  his estate or legal  representative,  as the
     case may be,  except that the  Company  shall (i) pay to  Executive  within
     sixty (60) days after the Date of  Termination  (A)  amounts  due and owing
     under Sections 4(b)(i) and 4(b)(iii) and (B) Executive's Annual Base Salary
     for  the  lesser  of the  six  (6)  month  period  following  the  Date  of
     Termination or the remaining portion of the Employment  Period,  reduced in
     the case of Disability by amounts  received by Executive under any employee
     disability  policy  maintained  by the Company for the benefit of Executive
     and (ii) provide Executive, his estate or legal representative, as the case
     may be, with the benefits provided by Section 4(b)(ii).

     5. Additional Payment.

     Upon a Change in Control,  Executive  shall be  entitled to a payment  (the
"Additional  Payment") equal to the product of (A) 61,971  multiplied by (B) the
amount by which (i)(x) the value of the  consideration  per share received or to
be received by the shareholders of the Company in connection with such Change in
Control  event or (y) in the event the Change in Control  does not result in any
payment to the  shareholders  of the Company,  the average of the last  reported
sale  price  of the  Company's  Common  Stock  for the  five  (5)  trading  days
immediately preceding the effective date of such Change in Control, exceeds (ii)
$12.75.  Such  Additional  Payment  shall be paid to  Executive  within five (5)
business days after the effectiveness of such Change in Control,  subject to all
withholdings required by law.

     6. Nonexclusivity of Rights.

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future participation in any plan,




                                      E-35
<PAGE>

program,  policy or practice provided by the Company and for which the Executive
may qualify,  nor shall anything herein limit or otherwise affect such rights as
the Executive may have under any contract or agreement with the Company. Amounts
which are vested  benefits  or which the  Executive  is  otherwise  entitled  to
receive  under any plan,  policy,  practice  or  program of or any  contract  or
agreement with the Company at or subsequent to the Date of Termination  shall be
payable in accordance with such plan, policy, practice or program or contract or
agreement, except as explicitly modified by this Agreement.

     7. Successors; Binding Agreement.

          (a) The Company will require any successor (whether direct or indirect

Corporation in the performance of his duties hereunder upon  presentation by the
Employee to the Corporation of appropriate vouchers.

     6.  Involuntary  Termination.  If the  Employee  dies  during  the  Term of
Employment,  his employment hereunder and the Term of Employment shall be deemed

     7.  Termination For Cause.  The Corporation may terminate the employment of
the Employee hereunder and the Term of Employment at any time during the Term of
Employment for "cause" (such termination being hereinafter called a "Termination
For Cause") by giving the Employee notice of such  termination,  upon the giving
of which such  termination  shall take effect  immediately.  For the purposes of
this Section 7, "cause" shall mean (i) the Employee's  willful  misconduct  with

or  commission  or  conviction  of a felony,  or (iv)  failure  to abide in some
material respect by the Corporation's rules of conduct, terms and conditions set
forth in the Corporation's handbook, as amended from time to time.

     8. Termination  Without Cause. The Corporation may terminate the employment
of the Employee hereunder and the Term of Employment at any time without Acause"
upon thirty (30) days prior written notice (such  termination  being hereinafter
called a "Termination  Without Cause").  Upon a Termination without Cause during
the Term of  Employment,  Employee  shall be entitled to receive his Base Salary
for twelve (12) months and his Base Salary for an additional  twelve (12) months
or in the latter case until Employee obtains  comparable  employment,  whichever
occurs sooner,  plus all earned but unpaid bonus at the time of termination.  In
addition,  upon a Termination  Without Cause at any time, the Corporation  shall
continue to pay the  Employee's  family  medical  insurance  premiums  under the
Corporation's medical insurance plan and other benefits (including  outplacement
benefits)  provided in Section 5.1(c) for twenty-four (24) months following such
termination or until Employee obtains  comparable  employment,  whichever occurs
sooner.

     9. Voluntary Termination. Any termination of the employment of the Employee
hereunder  otherwise  then  as  a  result  of  an  Involuntary  Termination,   a
Termination  For Cause or a  Termination  Without  Cause shall be deemed to be a
"Voluntary Termination". A Voluntary Termination shall be deemed to be effective
immediately upon such termination.

     10. Effect of Termination of Employment.

     (a) Upon the termination of the Employee's employment hereunder pursuant to
a Voluntary  Termination,  Involuntary  Termination or a Termination  For Cause,
neither the



                                      E-42

Employee nor his  beneficiary  or estate shall have any further rights or claims
against the Corporation under this Agreement except to receive:

          (i) the unpaid  portion  of the Base  Salary  provided  for in Section
     5.1(a),  computed on a pro rata basis to the date of termination,  plus any

     have theretofore been reimbursed as provided in Section 5.1(d);

          (iii) payment of all accrued and unused vacation time.

     (b) Upon the termination of the Employee's employment hereunder pursuant to
a Termination Without Cause,  neither the Employee nor his beneficiary or estate
shall have any  further  rights or claims  against  the  Corporation  under this
Agreement except to receive a termination  payment equal to that provided for in
Section 10(a) hereof, plus the amounts set forth in Section 8, if any.
