Item 1. Business

Introduction

         Osteotech,  Inc.  (the  "Company"  or  "Osteotech"),  formed  in  1986,
provides  services  and  develops  and  markets  products  to  the  orthopaedic,
neurological,  oral/maxillofacial,  dental and general  surgical  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 processing human
allograft  bone,  ligaments  and  tendons  (collectively,   "bone  tissue")  for
transplantation,  ceramic  (hydroxyapatite)  and titanium  plasma spray  coating
services and producing and marketing  ceramic based products to the orthopaedic,
dental and ear,  nose and throat  ("ENT")  implant  markets.  The Company is the
exclusive  United  States  distributor  of all spinal  instruments  and implants
manufactured  by Heinrich C. Ulrich,  KG  ("Ulrich"),  a medical  device company
based in Ulm, Germany.


Overview

         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  diseases.  For  such
procedures the surgeon may use autograft bone tissue, allograft bone tissue or a
combination of both.  Autograft bone tissue is acquired from another part of the
patient's skeleton,  most often by an additional operative procedure.  Allograft
bone tissue is bone tissue previously obtained from cadavers or surgical patient
donors.  The Company  estimates that the current total U.S. bone graft market is
approximately $406 million annually, of which allograft bone grafting procedures
constitute approximately $122 million.

         Allograft tissue is procured by a network of bone banks,  substantially
all of which are not-for-profit  organizations.  Management believes, based upon
its knowledge of the industry,  that the Company  processes  more allograft bone
tissue  than  any  other  processor  in the  world.  Certain  of  the  Company's
competitors,   particularly   those  involved  with  synthetic  bone  substitute
materials,  attempt to compete by fostering a  perception  that  utilization  of
processed  allograft human bone tissue poses a significant  threat of infectious
disease  transmission.  To the Company's  knowledge,  none of the  approximately
1,200,000  transplanted  grafts it has processed  since it commenced  processing
bone  tissue in 1987 have  resulted in a confirmed  transmission  of  infectious
disease. This record is due to the rigorous donor

                                       -1-

<PAGE>



screening and tissue  recovery  techniques  employed by the  Company's  clients,
extensive donor testing, as well as Osteotech's  demanding quality assurance and
processing protocols.

         Osteotech  processes  allograft bone tissue for its customers which pay
the Company fees, on a per donor basis, for processing,  finishing and packaging
their tissue. Once processed, the bone tissue is returned to these customers for
distribution  to surgeons  and medical  institutions.  The  surgeons and medical
institutions  pay the Company's  customers' fees  established by such customers.
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
bone  tissue  used.  The cost to the patient  for the  processed  bone tissue is
generally reimbursable by medical insurance carriers as part of the overall cost
of the procedure.

         Processing by the Company yields a wide array of  freeze-dried,  frozen
and  demineralized  bone  tissue  that  is used  by  orthopaedic,  neurological,
plastic,  dental,  periodontal  and  oral/maxillofacial  surgeons  to repair and
replace bone loss caused by trauma or certain disease states, augment prosthetic
implant procedures, replace damaged ligaments and tendons and in connection with
spinal  fusion  procedures.  Osteotech  believes  its  processing  methods,  its
customers'  tissue  recovery  techniques and the multiple  screening and testing
procedures  employed,  reduce the risk of transmissions of infectious agents and
the potential  toxicity of the allografts.  Studies  completed by an independent
testing laboratory  specializing in viral inactivation studies demonstrated that
a proprietary  demineralization  process of the Company can virtually inactivate
and eliminate the HIV virus (the process reduces the probability of transmission
of the HIV virus to one in 2.8 billion),  as well as the hepatitis B,  hepatitis
C, cytomeglia and polio viruses. In addition to its proprietary demineralization
process,   Osteotech  expects  to  begin  to  implement  additional   processing
technologies  in 1997 that once fully  implemented  will  enable the  Company to
expand its viral inactivation claims to include virtually all of the bone tissue
it processes.  These proprietary,  tissue-specific  technologies are expected to
further  enhance  graft  safety  while  maintaining  the  tissue's  biologic and
physical  properties.  There can be no  assurance,  however,  that  despite  the
quality  control  measures  employed by the Company  and its  customers  and the
processing  methods utilized by the Company,  processed bone tissue will be free
of infectious agents,  including the HIV virus and hepatitis.  See "Services and
Products  -  Allograft   Processing   Technology"  and  "Product  Liability  and
Insurance."

         Osteotech  processes  allograft bone tissue  pursuant to contracts with
several large national and international  not-for-profit organizations which are
responsible for donor procurement and distribution of the processed bone tissue.
The Company is the

                                       -2-

<PAGE>



exclusive  processor for two of the largest tissue procurement  organizations in
the  United  States - the  Musculoskeletal  Transplant  Foundation  ("MTF"),  an
organization   comprised  of  medical  teaching   institutions  and  independent
procurement agencies and American Red Cross Tissue Services ("ARC"). The Company
is also the exclusive processor for BioImplant Services, The Netherlands.

         Industry data  indicates  that  utilization of allograft bone tissue in
musculoskeletal  surgical  procedures  is  continuing  to increase.  The Company
estimates  that the current total U.S. bone graft market is  approximately  $406
million annually,  of which the allograft segment,  which grew approximately 20%
in 1996, is approximately $122 million.  Some of the factors contributing to the
increased utilization of allograft bone tissue include:

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

         .        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, chronic pain and deformity;

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

         .        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

         .        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 utilized in surgical procedures because of its
biomechanical and biologic  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 gives the bone
weight-bearing  properties,  and  therefore,  is commonly used in surgery on the
extremities and the spine and in other procedures  requiring  strong  transplant
material.  Cancellous  bone,  the spongy  internal  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 the  weight-bearing  strength of the graft is not paramount.
Therefore,  cancellous bone is often used to fill smaller areas of bone loss and
to augment more extensive

                                       -3-

<PAGE>



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.

         Through  its  subsidiary,  HC  Implants  BV ("HC  Implants"),  based in
Leiden,  The Netherlands,  the Company was involved in manufacturing,  marketing
and developing  products utilizing its PolyActive  polymer. In October 1996, the
Company discontinued  development  activities related to its PolyActive polymer.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations".  HC Implants'  subsidiary,  CAM  Implants BV ("CAM"),  is providing
ceramic  hydroxyapatite  ("HA")  plasma spray  coating  services to the European
orthopaedic  and dental  implant  markets and also produces and markets  ceramic
products for use in orthopaedic,  dental and ENT surgical implant  procedures in
Europe.  Through a joint  venture  with  APS-Materials,  Inc.  ("APS"),  CAM has
expanded  its  operations  in  Europe  to  include   titanium  and   combination
titanium-HA  plasma  spray  coating  services.  HC  Implants'  subsidiary,   CAM
Implants,  Inc., has licensed its ceramic plasma spray coating operations in the
United  States and Canada to APS. See  "Services  and Products - Ceramic  Plasma
Spray Coating Services and Products."

         In 1993, the Company entered into an agreement for the exclusive United
States marketing and distribution rights for the Universal Spine Instrumentation
System  (USIS(R))  and all other  implants  and  instruments  for spine  surgery
developed by Ulrich. Included in the USIS product group is the Zielke VDS spinal
implant  system,  which  is  comprised  of  instruments  and  implants  used  by
orthopaedic and neurological  surgeons to correct curvatures of the spine caused
by disease, trauma and degeneration, and is currently in use worldwide.

Company Strategy

         Since its formation in 1986,  Osteotech has become the world's  largest
processor  of  allograft  bone  tissue.  The  Company's  strategy  is to use its
position as a leader in this field to continue to educate the medical  community
and the general public as to the benefits of allograft bone grafting procedures,
thereby  increasing  surgeon and patient  demand for allograft bone tissue which
has been processed by Osteotech. The Company will also seek to use its expertise
in the  allograft  processing  area to  develop  new  forms of bone  tissue  and
products with a broader range of applications  in  musculoskeletal  surgery,  as
well  as to  increase  the  potential  tissue  yield  from a  single  donor.  In
furtherance of this goal, the Company has developed and is utilizing an advanced
proprietary  demineralization  process  which,  when  applied to cortical  bone,
results in allograft bone tissue which the Company believes  retains  osteogenic
capabilities  greater than those of most currently  available forms of allograft
bone tissue.  As a result,  the Company has been able to successfully  introduce
the  use of  demineralized  bone  tissue  in a  broad  spectrum  of  orthopaedic
procedures. See "Services and Products - Allograft Processing Technology."

         Osteotech's  leadership  in allograft  tissue  processing  continues to
strengthen  through  Grafton(R)  Demineralized  Bone Matrix ("Grafton DBM"), the
Company's innovative and proprietary demineralized bone grafts.

         Grafton DBM Gel, the Company's first Grafton form,  introduced in 1991,
offers  surgeons  unique  handling  characteristics  when  performing bone graft
procedures  as part of spinal  fusions,  joint  replacements  and the  repair of
osseous defects.  With the  introductions of two new innovative forms of Grafton
in 1996,  Grafton DBM Flex and Grafton DBM Putty,  plus wider  distribution  and
deeper market penetration achieved through a combination of effort by a national
network of independent  agents and the Company's  direct  marketing  force,  the
Company  anticipates  further growth for Grafton processed allograft tissue. The
Company's Grafton DBM forms have been utilized in over 120,000 procedures.

         In January 1996,  Osteotech  introduced  Grafton DBM Flex.  Grafton DBM
Flex is a flexible  "pressed  fiber"  form of  demineralized  bone which for the
first time gives surgeons a pliable form of bone graft.  Initially  available in
5cm by 5cm square and 2.5cm by 10cm  strips,  Grafton  DBM Flex  conforms to the
body's  natural  anatomy  and can be easily cut for precise  adaptation  to host
bone.

         Additionally, in November 1996, Osteotech introduced Grafton DBM Putty,
a moldable, putty-like graft of entangled fibers of demineralized bone, which is
easily mixed with marrow and other grafts.


                                       -5-

<PAGE>



         Supporting the Company's Grafton DBM expansion is Osteotech's  national
network of independent  sales agencies.  Specializing  in orthopaedic  products,
these agents develop and manage surgeon  relationships  in partnership  with the
Company's direct field marketing organization. This two-pronged strategy affords
Osteotech the best opportunity to gain maximum  coverage and market  penetration
for its Grafton DBM processed  allograft tissue. At the end of 1996, the network
totaled 47 agents and 216 representatives.

         The  Company  believes  that  the  product  development  and  marketing
conducted by its subsidiaries in The Netherlands furthers the Company's strategy
of  positioning  itself as a provider of services  and  products in the areas of
musculoskeletal and general surgery,  and that the Company's European operations
complement  Osteotech's  position in the United  States  orthopaedic  and dental
markets.  See "Services and Products - Ceramic Plasma Spray Coating Services and
Products" and "Research and Development."

         In furtherance of its goal to become a leading provider of services and
products  for  musculoskeletal  repair and to  further  leverage  its  marketing
force's  contacts with orthopaedic and  neurological  surgeons,  during 1993 the
Company  obtained the  exclusive  United  States'  marketing  rights to the USIS
spinal implant products and all other devices and instruments for spinal surgery
developed by Ulrich.  Osteotech  plans to continue  expanding its line of spinal
implant  devices and  instrumentation  through  its  relationship  with  Ulrich.
Subject to appropriate  regulatory approvals and Osteotech obtaining appropriate
product liability insurance  coverage,  a spinal implant system currently in use
in several  European  countries  and South Africa -- the SSCS System -- is being
readied  for  introduction  in the  U.S.  The  SSCS  System  offers  surgeons  a
proprietary  hinge screw  design that allows for load  sharing and  improves the
potential fusion rate in posterior thoracic and lumbar fusion procedures.


Services and Products

Allograft Processing Technology

         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 labelled.  Osteotech  processes its  customers'  tissue
utilizing  technology  which  yields a wide  array of  freeze-dried,  frozen and
demineralized  bone  tissues.  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.  Demineralized  bone tissue includes  cortical
powders, segments and struts.


                                       -6-

<PAGE>



         The suitability of an allograft is partly  dependent on the methods and
conditions used in the processing of the tissue. Processing includes the removal
of certain  portions of the 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,  techniques  have been  developed that minimize the use of chemicals
and procedures that might render the allograft less suitable for use as a graft.
The Company processes allograft 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. The Company believes that its
use  of  such  clean  room  techniques,   a  controlled   environment,   in-line
disinfection and other technologies preserves 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.

         The Company has  developed a proprietary  demineralization  process for
cortical bone which it believes yields 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. The Company's
process removes these inhibiting factors.

         Grafton DBM Gel, the Company's  first Grafton DBM form,  was introduced
in 1991.  Grafton DBM Gel utilizes the  Company's  proprietary  demineralization
process and offers surgeons unique handling characteristics when performing bone
graft  procedures as part of spinal fusions,  joint  replacements and repairs of
osseous  defects.  With the  introductions  of the two new  innovative  forms of
Grafton  DBM in 1996,  Grafton  DBM Flex  and  Grafton  DBM  Putty,  plus  wider
distribution  and deeper market  penetration  utilizing the national  network of
independent agents in combination with the Company's direct marketing force, the
Company anticipates further growth in the use of Grafton DBM processed allograft
tissue.  To date,  the  Company's  Grafton DBM forms have been  utilized in over
120,000 procedures.

         In January, 1996, Osteotech introduced Grafton DBM Flex.
Grafton DBM Flex is a flexible "pressed fiber" form of

                                       -7-

<PAGE>



demineralized  bone which for the first time  gives  surgeons a pliable  form of
bone graft.  Initially available in 5cm by 5cm squares and 2.5cm by 10cm strips,
Grafton DBM Flex  conforms to the body's  natural  anatomy and can be easily cut
for precise adaptation to host bone.

         Additionally, in November 1996, Osteotech introduced Grafton DBM Putty,
a moldable, putty-like graft of entangled fibers of demineralized bone, which is
easily mixed with marrow and other grafts.

         The FDA has the statutory  authority to regulate  allograft  processing
and  allograft-based  bone tissue.  On December 14, 1993, the FDA issued interim
rules  regulating the recovery,  processing,  storage and distribution of banked
human  tissue,  including  allograft  bone  tissue.  In  August  1995,  the  FDA
designated  Grafton DBM as within the scope of the  definition  of banked  human
tissue under the interim rules. See "Government Regulations."


Ceramic Plasma Spray Coating Services and Products

         The  Company is  providing  ceramic HA plasma  spray  coating  services
generally to large  orthopaedic  and dental  implant  companies  in Europe.  The
primary advantage of coating  orthopaedic and dental prosthetic  devices with HA
is that it enables bone to grow into the implanted  device,  thus  enhancing the
stability of the device.  Increased  stability  for  implanted  medical  devices
should  lower  the  amount  of bone  loss  incurred  over  time and  result in a
significant  reduction in pain caused by micro motion of the device. The Company
manufactures the HA powder which it uses in its plasma spray coating  operations
from raw materials which are readily available from several sources. The Company
also supplies HA powder to various  companies for use in their  in-house  plasma
spray coating operations.  Additionally,  the Company produces HA products which
are used to  replace  middle  ear bones and for the  repair of bone  defects  in
dental applications.  Further, the Company is pursuing  opportunities to utilize
its ceramic powders and technology as key components of products being developed
by other companies for the  orthopaedic and incontinent  care markets as well in
non-medical uses.

         To enhance its plasma spray  coating  services to the  orthopaedic  and
dental implant  markets and to reduce plasma spray coating  operating  costs, in
September  1993 the Company  entered into a joint  venture  agreement  with APS.
Pursuant to this agreement, in addition to its HA plasma spray coating services,
the Company began offering  titanium and  combination  titanium-HA  plasma spray
coating services in Europe.  Titanium, like HA coating, is applied to prosthetic
devices to facilitate attachment of bone to the prothesis.  Under the agreement,
the Company makes all decisions regarding the joint venture business and manages
its daily

                                       -8-

<PAGE>



operations,  and the Company's personnel perform the spray coating services, all
in return for a fee. The parties share equally in the joint venture's income and
losses.  The  joint  venture  absorbs  certain  of the  Company's  facility  and
personnel costs because it utilizes the Company's  facility and personnel in The
Netherlands.

         The Company granted an exclusive license,  with no right to sublicense,
to its HA plasma  spray  coating  technology,  to APS for the United  States and
Canada.  APS provides  HA,  titanium and  combination  HA-titanium  plasma spray
coating services.  The Company  transferred to APS at its Dayton, Ohio facility,
the equipment  and  technology  used in connection  with the Company's HA plasma
spray coating services for APS' use during the term of the agreement.  Under the
agreement,  APS is  required  to pay the  Company a royalty  equal to 15% of net
sales  of  HA  plasma  spray  coating   services  which  utilize  the  Company's
technology,  for  customers or  prospective  customers  contacted by the Company
prior to the date of the  agreement,  and 10% for all new customers  obtained by
APS;  provided,  that the  parties  will  review the  reasonableness  of the 10%
royalty on an annual basis and may adjust it downward if mutually  agreed.  Such
adjustment,  if any, will be based on, among other things,  competitive factors.
To date, no such adjustments have been made.


Transplant Support Products

         The Company  provides a line of transplant  support products for use by
donor recovery teams and/or surgeons, including recovery kits containing sterile
drapes  and  supplies  and  items  for  collecting  and  transporting  cadaveric
microbiologic  cultures and blood samples for later  analysis.  The Company also
markets Alloprep System(R) Allograft Tissue Reconstitution  Solution, a solution
for the reconstitution of freeze-dried allograft bone prior to transplantation.


Implants and Instruments

         In the U.S.,  Osteotech markets implants and instrumentation for spinal
surgery through an exclusive distribution agreement with Ulrich.

         Osteotech markets Ulrich's VDS Zielke System, an implant system used by
orthopaedic,  spinal and neurological surgeons worldwide -- often in combination
with banked bone grafts -- for the  anterior  correction  of spinal  deformities
caused by  disease,  trauma  and  degeneration.  The  Company  also  markets  an
extensive  line of more than 250 high quality,  specialty  surgical  instruments
manufactured by Ulrich.


                                       -9-

<PAGE>



         Like  allograft  tissue,  the market for spinal  implants  continues to
grow. It is estimated that the spinal  implant market in the U.S.  increased 23%
to $252 million in 1996.

         Osteotech  plans  to  continue  expanding  its line of  spinal  implant
devices and  instrumentation  through its relationship  with Ulrich.  Subject to
appropriate  regulatory  approvals and Osteotech  obtaining  appropriate product
liability  insurance  coverage,  a spinal  implant  system  currently  in use in
several  European  countries  and South  Africa  -- the SSCS  System -- is being
readied  for  introduction  in the  U.S.  The  SSCS  System  offers  surgeons  a
proprietary  hinge screw  design that allows for load  sharing and  improves the
potential fusion rate in posterior thoracic and lumbar fusion procedures.


Quality Assurance

         All bone tissue processed by Osteotech is obtained from customers which
are required by their agreements with the Company to employ  technicians  and/or
surgeons trained in aseptic tissue recovery using sterile  surgical  techniques.
The Company's  customers  recover tissue primarily in hospitals and, to a lesser
extent,  coroners' facilities which have been prepared for recovery. 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 bone tissue for processing.  Following
quarantine,   the  bone  tissue  is   processed   in  a   microbially-controlled
environment.  Under  constant  monitoring,  the  tissue  is  cleaned,  soaked in
antibiotics and then cut and shaped in accordance with customer  specifications.
Before being  released to customers,  all processed bone tissue is inspected and
again tested for microbiological contaminants by the Company's quality assurance
team.  Quality  control is  supported  through the use of  proprietary  software
programs  which provide  traceability  of bone tissue from donor to customer and
track each step of the processing operation.

         The  Company  believes  that the  serologic  screening  of donors,  the
extensive  screening of donor  profiles and medical  histories  performed by its
customers and its processing  technologies reduce the likelihood of the presence
of infectious agents, including the HIV and hepatitis viruses, in processed bone
tissue.  Studies completed by an independent testing laboratory  specializing in
viral  inactivation   studies   demonstrated  that  the  Company's   proprietary
demineralization  process can virtually  inactivate  and eliminate the HIV virus
(the process  reduces the probability of transmission of the HIV virus to one in
2.8 billion) as well as the  hepatitis  B,  hepatitis  C,  cytomeglia  and polio
viruses.  To  the  Company's  knowledge,  none  of the  approximately  1,200,000
transplanted  grafts it has processed since it commenced  processing bone tissue
in 1987 have resulted in a confirmed transmission of

                                      -10-

<PAGE>



infectious  diseases.  This record is due to the rigorous  donor  screening  and
tissue  recovery  techniques  used by the  Company's  clients,  extensive  donor
testing,  as well as  Osteotech's  demanding  quality  assurance and  processing
protocols. In addition to its proprietary  demineralization  process,  Osteotech
expects to begin to implement  additional  processing  technologies in 1997 that
once fully implemented will enable the Company to expand its viral  inactivation
claims  to  include  virtually  all of  the  bone  tissue  it  processes.  These
proprietary,  tissue-specific technologies are expected to further enhance graft
safety while maintaining the tissue's biologic and physical properties. However,
despite the Company's quality control  measures,  there can be no assurance that
processed bone tissue will be free of infectious  agents.  The Company  believes
that its processing  procedures  and quality  control  measures  comply with the
interim  rules for banked  human  tissue  instituted  by the FDA on December 14,
1993. See "Government Regulations."

         In December 1994, the Company's  facility in The  Netherlands  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. ISO certification for production facilities will be
mandatory  by  1998  for  companies  within  the  European  Union  ("EU").   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 EU member  countries to
administer the ISO certification process.


Research and Development

         During  1996,  1995 and 1994,  the  Company  spent  approximately  $4.4
million,  $3.7  million  and  $3.3  million,   respectively,   on  research  and
development  activities.  The  Company  is engaged in  continuing  research  and
development efforts with respect to its processing technology, ceramic HA plasma
spray coating services and ceramic products. Research and development efforts in
the  allograft  processing  field include the  Company's  continuing  efforts to
improve upon and  maintain  the safety and  performance  of the  processed  bone
tissue,  increase  the amount of  transplantable  bone tissue  derived from each
donor, reduce processing costs through efficiency advances and develop new forms
of allograft bone tissue.


Customers

         Osteotech is the exclusive processor of allograft bone tissue for large
national and international not-for-profit  organizations.  The Company generally
charges its customers on a per donor basis,  or for proprietary  products,  on a
per unit basis, for fees for

                                      -11-

<PAGE>



direct and indirect  processing  costs and for finishing and packaging each unit
of bone tissue  produced.  Osteotech's  agreements with its customers  generally
provide for the Company to indemnify its customers against liability arising out
of defects in  allograft  bone tissue  caused as a result of  processing  by the
Company and for the Company to provide  such other  services as may be requested
by the  customer on such terms as the  customers  and the Company may agree from
time to time.  During 1996, MTF and the ARC accounted for  approximately 64% and
25%,  respectively,  of the Company's revenues. The Company has a new processing
agreement with ARC which runs through  December 31, 2006. The Company's  current
agreement  with MTF  expires  on March 31,  1997 and the  Company  is engaged in
negotiations with MTF for a new agreement.  There can be no assurance that a new
agreement  with MTF will be completed on terms  favorable to the Company,  if at
all. The loss of either MTF or ARC as a customer or a  substantial  reduction in
the amount of allograft  bone tissue used by each customer would have a material
adverse effect on the Company.

         Osteotech does not engage in donor procurement or tissue
distribution and therefore relies on its not-for-profit customers
to obtain donor bone tissue for processing by the Company, and to
distribute the processed bone tissue to hospitals and physicians
for transplantation.  See "Education and Marketing."

         Customers of the  Company's  plasma spray  coating  services  generally
purchase  such  services  pursuant to purchase  orders or  non-exclusive  supply
agreements which are cancelable at any time by either party.


Relationship with Musculoskeletal Transplant Foundation

         In 1987, the Company  assisted in the formation of MTF, an organization
comprised of medical teaching institutions and independent procurement agencies,
for the purpose of expanding the science of musculoskeletal transplantation. MTF
is now one of the largest bone tissue  procurement  organizations  in the United
States,   responsible   for  the   procurement  of  allograft  bone  tissue  for
distribution to its members as well as unaffiliated  hospitals.  MTF is governed
by a board of directors and a management team, all of whom are unaffiliated with
the Company.

         In March 1987, Osteotech entered into a ten-year service agreement (the
"Service  Agreement")  with MTF  whereby  the  Company  serves as the  exclusive
processor of all musculoskeletal allograft bone tissue procured by MTF. Pursuant
to the Service  Agreement,  the  Company  agreed to increase  its  capacity,  if
necessary, to meet MTF's requirements for bone tissue processing.  Osteotech has
agreed that the pre-tax  profit earned from  services  which it performs for MTF
will not  exceed the  average  pre-tax  profit of the 15 largest  pharmaceutical
concerns in the United States. MTF

                                      -12-

<PAGE>



assigned to the Company  certain rights to license  technology  developed by its
members pursuant to research grants made by MTF.


Relationship with American Red Cross

         In December  1996,  the Company  entered  into an  agreement  (the "ARC
Agreement")  with ARC whereby the Company  serves as the exclusive  processor of
all  musculoskeletal  allograft bone tissue donors  procured by ARC. The Company
believes it can respond in a timely  manner to any  increase in demand by ARC or
other customers  through the maximum  utilization of its existing  facilities or
the establishment of additional  temporary or permanent  processing  facilities.
The ARC Agreement  expires on December 31, 2006.  Either party may terminate the
ARC Agreement at any time upon:  (i) a material  breach by the other party which
is unremedied  for ninety days and (ii) the insolvency of the other party or any
bankruptcy or insolvency proceedings or the levy of any writ or judgment against
the other party. In addition,  ARC may terminate the Processing Agreement in the
following  circumstances:  (i) upon ninety days written notice to the Company of
its  determination  to end its  program of  procuring  or  distributing  tissue,
provided  that, if ARC resumes such program,  it shall  provide  prompt  written
notice to the Company of such  resumption  and the ARC  Agreement  shall  become
effective again on the same terms as prior to the  termination,  (ii) if a third
party develops a commercially  feasible processing technology that a third party
review board determines to be safer or more effective than the Company's and the
Company is unable or unwilling to provide such product or service,  and (iii) if
the FDA implements new regulations and the Company fails to implement changes to
its tissue  processing to conform to such changes.  If ARC enters an arrangement
with a third party  whereby  tissue  processed by the Company is used in a third
party's technology or product,  ARC shall inform the Company of this arrangement
and the Company  shall have the right to  terminate  with 90 days prior  written
notice or to renegotiate the terms of the agreement.


Other Customers

         In September 1988, the Company  entered into a ten-year  agreement with
BioImplant Services ("BioImplant"),  a tissue donor procurement and distribution
organization  in Europe,  whereby the  Company  has  agreed,  subject to certain
exceptions,  to be the exclusive  provider of allograft  bone tissue  processing
services  for  BioImplant.  The Company has also agreed that it will not process
bone tissue for other procurement  organizations in certain designated  European
territories.  The Company has agreed to meet the annual volume  requirements  of
BioImplant.


                                      -13-

<PAGE>



         The Company also has an agreement  with the University of California at
Irvine,  a medical  teaching  institution,  to  provide  allograft  bone  tissue
processing  services  which is  renewable  annually.  To date,  revenues  to the
Company pursuant to this agreement have not been material.


Competition

         Allograft  bone tissue  competes with  autograft  bone tissue which has
traditionally  been utilized for human bone  transplants.  The Company  believes
that where the use of autograft is feasible,  surgeons and their  patients  will
generally  continue,  at least over the near term, to choose this option in view
of the perceived risk of transmission of infectious  agents  associated with the
transplant of allograft bone tissue.  For numerous  circumstances and procedures
for which  autograft  transplantation  is either not feasible or not  desirable,
there are a number of competing alternatives available, including allograft bone
tissue processed by others.

         The  Company  believes  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 the  Company.  Osteotech  believes it
competes with such entities on the basis of its advanced  processing  technology
and the quality and quantity of the bone tissue its processing yields. Since the
Company  introduced its allograft tissue processing  technology in 1987, certain
competing  processors have responded with claims of having developed  technology
similar to that used by the Company.  Although the Company believes,  based upon
its  knowledge  of  the  industry  (but  in the  absence  of  reliable  industry
statistics),  that it  processes  bone  tissue  from more  donors than any other
processor in the world,  there can be no assurance that the Company can continue
to compete successfully in the area of allograft processing.

         Allograft bone tissue also competes in certain bone grafting procedures
with synthetic bone void filler products.  To date, these medical devices may be
legally  promoted  in the  United  States  for only a  minority  of the types of
applications  and  procedures  in which  allograft  bone tissues are used.  Bone
grafting  procedures in which allograft bone tissue might be used also sometimes
compete  indirectly with non-invasive  bone growth  stimulator  devices in those
cases in which bone graft surgery is not the preferred course of treatment.

         With respect to allograft bone tissue, the Company expects
increased competition from synthetic bone substitutes and
recombinant bone growth stimulating materials.  Synthetic

                                      -14-

<PAGE>



substitutes  now being  marketed  include HA, a ceramic  substance  with an open
weave which  allows for partial  penetration  of bone and  fibrous  tissue,  and
combinations of HA and other substances, which have been approved by the FDA for
some oral surgical applications.  The FDA has approved two of these HA synthetic
bone substitutes for certain  orthopaedic  procedures.  The primary advantage of
synthetic bone  substitutes is the absence of dependence on the  availability of
human donors.  In addition,  synthetic  materials may be perceived by members of
the medical community and the general public as safer than  allograft-based bone
tissue.  Osteotech believes,  however, that the bone tissue it processes will be
able to compete with synthetic bone substitutes on the basis of the biologic and
physical properties,  its multiple applications for various surgical procedures,
its successful use over an extended period of time without  confirmed  instances
of infectious disease  transmission,  and the fact that independent  researchers
have reported that the Company's  proprietary  process can virtually  inactivate
and eliminate the HIV virus and other viruses in  demineralized  tissue,  should
they be present.

         In  addition to its  proprietary  demineralization  process,  Osteotech
expects to begin to implement  additional  processing  technologies in 1997 that
once fully implemented will enable the Company to expand its viral  inactivation
claims  to  include  virtually  all of  the  bone  tissue  it  processes.  These
proprietary,  tissue-specific technologies are expected to further enhance graft
safety while maintaining the tissue's biologic and physical properties.

         The  Company is also aware of entities  seeking to develop  bone growth
factors using  recombinant  technology.  Two such  companies have announced that
human clinical trials are in progress on their  recombinant bone growth factors.
There can be no  assurance  that the  allograft  bone  tissues  processed by the
Company will be able to compete successfully with synthetic bone substitutes and
recombinant  bone growth  factors  which are  developed  and  commercialized  by
others.  Lastly,  other companies engaged in the manufacture of medicine implant
devices for the orthopaedic  field may enter the allograft market in competition
with the Company.  Such companies may have  substantially  greater resources and
expertise  than the Company.  Accordingly,  there can be no  assurance  that the
Company would be able to compete successfully with any such companies.

         The  Company's  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,  the Company also faces
competition  from medical  implant  companies  which have in-house  plasma spray
coating  operations.  The  Company  competes  primarily  on the  quality  of its
coatings and price. Osteotech believes that the spraying

                                      -15-

<PAGE>



technology it uses, which is computer controlled and utilizes robotics,  enables
it to provide high quality coatings at competitive  prices.  It should be noted,
however, that the ceramic coating industry is highly competitive, certain of the
Company's  competitors have greater  resources than the Company and there can be
no assurance the Company will be able to compete successfully.


Education and Marketing

         Osteotech believes the markets for processed allograft bone tissue will
continue  to  be  orthopaedic,   neurological,  plastic  and  oral/maxillofacial
surgical  specialties.  The  Company's  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.  There are currently 19 persons employed by the Company to engage in
efforts to educate  surgeons as to the  benefits and  applications  of processed
allograft bone tissue.  Notwithstanding its internal marketing  capability,  the
Company  is still  dependent  to a degree on the  success of the  education  and
marketing  activities conducted by its customers and their  representatives.  To
complement  the  Company's  education  and  marketing   strategy,   the  Company
commenced,  in the  fourth  quarter of 1994,  to  develop a national  network of
independent  sales agents who assist in the Company's  marketing of products and
services and further educate the medical  community  about  processed  allograft
bone tissue.  Currently these sales agents are focusing their efforts  primarily
on Grafton DBM and spinal  instruments.  At December 31,  1996,  the Company had
appointed 47 agencies with 216 sales representatives.

         The Company is pursuing a strategy of licensing or acquiring additional
products which are ready to be  commercialized in order to take advantage of the
Company's expertise and relationships within the orthopaedic community.

         A small  in-house  marketing  staff  located  at the  Company's  Leiden
facility  markets  the plasma  spray  coating  services  of the  Company and the
Company's joint venture with APS. 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. The Company markets
its HA powders and ceramic products through independent contract representatives
in Europe.


Government Regulations

         The procurement and transplantation of allograft bone tissue is subject
to federal regulation pursuant to the National Organ Transplant Act ("NOTA"),  a
criminal  statute  which  prohibits  the  purchase  and  sale of  human  organs,
including bone and related

                                      -16-

<PAGE>



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.  The Company
provides  services  in all of these  areas,  with the  exception  of removal and
implantation. Osteotech and other bone processors are engaged in ongoing efforts
aimed at  educating  the  medical  community  as to the  benefits  of  processed
allograft  bone tissue and the Company  will  continue to expand its  activities
with respect to Grafton DBM.  Although  the Company  believes  that NOTA permits
reimbursement   of  these  costs  as  costs   associated  with  the  processing,
transportation  and  implantation of bone tissue  products,  the inability to be
reimbursed for its education  efforts in the future could  adversely  affect the
Company's  business and  prospects.  No federal  agency or court has  determined
whether NOTA is, or will be, applicable to every allograft-based  material which
may  derive  from the  Company's  processing  technologies.  Assuming  that NOTA
applies to Osteotech's processing of allograft bone tissue, the Company believes
it is in  compliance  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 the  Company's
method of operations. See "Education and Marketing."

         In December 1993, the FDA introduced interim regulations  applicable to
human tissue  intended  for  transplantation,  including  the types of allograft
tissues processed by the Company.  The FDA had not previously  treated the field
of tissue  banking and tissue  products as medical  specialties  and allowed the
organizations in the field to regulate  themselves.  However,  the growth of the
field and other factors prompted the FDA to introduce  universal basic standards
to  reduce  the  risk  of  transmission  of  infectious   diseases  through  the
inadvertent use of infected  tissue.  The Company's  operations are dependent on
adequate  compliance  with these rules by both the Company and its clients.  The
Company believes that its operations and those of its clients are in substantial
compliance  with those rules.  The FDA is moving to finalize the current interim
regulations.  Additionally,  on February 28, 1997,  the FDA proposed a framework
for  more  comprehensive  regulations  of  cellular  and  tissue-based  products
including Allograft tissues such as those processed by the Company. There can be
no assurance  that the Company or its clients will be in  compliance  with these
more comprehensive rules if and when they are promulgated by the FDA.

         In August 1995, the FDA  designated  Grafton DBM as within the scope of
the  definition  of banked  human  tissue under the interim rule on human tissue
intended for  transplantation.  Banked human tissues such as demineralized  bone
matrix  have  been  considered,  and  still  are  considered,  exempt  from  FDA
premarketing clearance requirements imposed upon medical products such as drugs,
devices and biologics.  Grafton DBM is a demineralized bone matrix that is mixed
with glycerol, a basically inactive substance, to provide

                                      -17-

<PAGE>



desirable physical handling characteristics to the demineralized
bone matrix.

         The Company  maintains a master  file for its HA plasma  spray  coating
processes  with the FDA.  The  Company's  customers  are  required to obtain FDA
clearance  for the marketing in the United  States of their  implants  which are
coated by the Company.  These  customers  refer to the Company's  master file in
their application for clearance by the FDA of their implants as medical devices.
The Company's European HA plasma spray coating services meet existing regulatory
requirements in the specific countries where they are marketed.

         Ceramic (HA)  products  which are produced by the Company are currently
distributed only in Europe. These products meet existing regulatory requirements
in the specific countries where they are produced and marketed. The Company does
not intend currently to market these products in the United States;  however, if
it does decide to do so, these products would require premarketing  clearance by
the FDA as medical devices.

         HA powder produced and sold in bulk by the Company in the United States
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.

Environmental Matters

         The  Company's  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 the  Company  and  disposed  of through a licensed
hazardous  waste  transporter in compliance  with  applicable  regulations.  The
production of HA powder at the Company's  facility in The Netherlands  generates
small  amounts of  hazardous  waste,  which is  segregated  by the  Company  and
disposed of through a licensed hazardous waste transporter. The Company has been
issued a Nuisance  Permit  from the local  government  for its  facility  in The
Netherlands.

         Although  the Company  believes  it is in  compliance  with  applicable
environmental  regulations,  the failure by the Company 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 the Company'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 Company  projects which have
been  independently  developed by the  consultants or researchers at the medical
institutions.

         At March 3, 1997,  the Company held a total of 24 patents in the United
States and foreign countries relating to its aseptic  processing  technology and
its transplant  support  products,  two United States and three foreign  patents
relating to its  biomaterial  technology,  eight United  States and four foreign
patent  applications  relating to aspects of its  processing  technology and its
osteogenic  and other  products  under  development  and three United States and
three foreign patent applications relating to its biomaterial technology.  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 the Company's.


Product Liability and Insurance

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

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

         The Company  presently  maintains  product  liability  insurance in the
amount of $20 million per occurrence and per year in the

                                      -19-

<PAGE>



aggregate.  There can be no assurance  that the Company will be able to maintain
such  insurance in the future or that such insurance will be sufficient to cover
all liabilities.  In addition,  the Company's  current insurance policy will not
cover any claims made against the Company  which are based upon a surgeon's  use
of a device in a manner  other than the use approved by the FDA for such device,
regardless of whether the Company advised the surgeon and/or healthcare provider
of the FDA approved use and provided  adequate  warnings  against any unapproved
use by the surgeon and/or healthcare provider.

         Of the twenty-nine lawsuits discussed in "Legal Proceedings,"
four such lawsuits would be covered by the Company's insurance
policies.  Twenty-five of the current lawsuits, and any lawsuits
filed in the future which contain claims similar to those contained
in such current lawsuits, may not be covered by the Company's
current insurance policy.  See "Legal Proceedings."

         Pursuant to its  distribution  agreement  with the Company,  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
or willful  misconduct or  unauthorized  claims made by the Company in marketing
the products. In accordance with such indemnification obligation, the Company is
entitled to be named as a co-insured on the product  liability  insurance policy
maintained  by  Ulrich.  Vericherunges-Aktiengesellchaft  ("Allianz"),  Ulrich's
insurance carrier,  has presented the Company with a certificate which indicates
that the Company is co-insured on such insurance  policy,  however,  Allianz has
indicated  that it does not  believe the  Company is a  co-insured.  This policy
provides coverage of 4,000,000 Deutsche Mark (DM) (approximately $2.6 million at
current  exchange  rates) per  person and  16,000,000  DM  (approximately  $10.4
million at current exchange rates) in the aggregate. The Company and Allianz are
engaged in  discussions  concerning  the Company's  coverage under the insurance
policy  maintained  by Ulrich with Allianz.  There can be no assurance  that the
Company  will in fact be  indemnified  by Ulrich or be provided  coverage  under
Ulrich's insurance policy or that such coverage, if provided, will be adequate.

Employees

         At December 31, 1996,  Osteotech  had 210  employees,  of whom 119 were
engaged  in  allograft   processing,   ceramic  plasma  spray  coating  and  the
manufacture  of products;  25 in research and  development;  31 in education and
marketing  and 35 in  regulatory,  finance  and  administration.  The  Company's
employees are not covered by any collective  bargaining  agreement.  The Company
considers relations with its employees to be good.

Item 2.  Properties

         The Company'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  2004 and provides for a base annual  rental of
approximately  $264,000.  This facility is occupied by the Company's  corporate,
financial,  administration,  marketing, research and development, regulatory and
clinical affairs staff.

         The Company's  processing  facility is located in approximately  30,000
square feet of space in Shrewsbury,  New Jersey which is occupied  pursuant to a
lease which  expires in February  2007 and provides for a base annual  rental of
approximately  $239,000  for the first five years of the lease and  $261,000 for
the remaining term of the lease.  The lease is renewable at the Company's option
for an additional five year term.

         The  Company's  European  subsidiaries  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  626,000  dfl  (approximately  US  $360,000  at the
December 31, 1996 exchange rates).

         The Company  believes that these  facilities  are adequate and suitable
for its current needs.

Item 3.  Legal Proceedings

         Orthopedic Bone Screw Products Liability Litigation

         The Company  has been named and served in  approximately  28  lawsuits,
involving   approximately  4000  plaintiffs,   brought  against  spinal  implant
manufacturers,  distributors  and promoters in various state and federal  courts
throughout  the  country.  The  majority  of these  actions,  all of  which  are
individual lawsuits and not class actions, are pending in federal court and have
been or are in the process of being  consolidated with other similar actions for
coordinated  proceedings  in the  District  Court for the  Eastern  District  of
Pennsylvania  in  an  action  entitled  In re  Orthopedic  Bone  Screw  Products
Liability Litigation,  MDL Dkt. 1014 (E.D. Pa.). These actions sound in products
liability and involve allegations of, either alone or in combination, negligence
and conspiracy or other concerted action.

         The vast majority of the complaints in these cases have been amended or
refiled due to defective  pleading as indicated by various court  orders.  Thus,
for these cases,  responsive  pleadings  have not yet been filed by  defendants,
including  the  Company.  As to the  remaining  cases,  they  are  still  in the
preliminary  discovery  stages.  Further,  on a daily basis, the number of cases
naming the Company may increase or decrease. Generally, the Company will not

                                      -21-

<PAGE>



be aware that it has been named as a  defendant  in an action  until it has been
served with the underlying complaint.

         As  to  all  of  these  actions,  the  Company  believes  that  it  has
affirmative  defenses,  including  without  limitation,  defenses  based  on the
learned intermediary defense, the failure of a cause of action to exist where no
malfunction of a Company-distributed  device occurred, the fact that the product
at issue was substantially  modified in an unforeseeable  manner,  the fact that
the product  distributed  by the Company was not the product at issue,  the fact
that the Company has not engaged in a  conspiracy  with other  manufacturers  or
distributors,  and the fact that the claims in all of these  actions are without
merit.  Accordingly,  all such  cases  are and will  continue  to be  vigorously
defended.

         All of the actions  seek  monetary  damages of no less than $50,000 per
plaintiff.  The  aggregate  monetary  damages  eventually  sought  by all of the
plaintiffs  and the  related  costs to defend  such  action may be  substantial.
Pursuant to the Company's  distribution  agreement with Ulrich, the manufacturer
of the spinal system distributed by the Company,  Ulrich has agreed to indemnify
the Company 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
the Company.

         Additionally,   the  Company  maintains  its  own  products   liability
insurance coverage from Lexington Insurance Company  ("Lexington") and Lexington
has been notified of these actions.  Lexington has denied  coverage with respect
to certain of these cases. Further,  Ulrich maintains its own products liability
coverage  from  Allianz.   Allianz  has  indicated  that  it  is  reviewing  the
possibility  of  extending  insurance  coverage to the Company  with  respect to
certain of these cases.

         Kehr et al. v. Musculoskeletal Transplant Foundation and
         Osteotech, Inc., Case No. 96-CV-334 (W.D. Mich.)

         On March 26, 1996, the Company was served with a lawsuit that was filed
in Kent County Circuit Court in Grand Rapids,  Michigan.  The action is based on
products  liability and negligence,  alleging that the Company and  co-defendant
MTF mislabeled and mispackaged  processed human bone tissue.  On April 24, 1996,
codefendant MTF, with the Company's  consent,  removed this action to the United
States District Court for the Western District of Michigan.

         On May 29,  1996,  the Company  filed its  answer,  denying any and all
liability,   and  setting  forth  affirmative   defenses,   including,   without
limitation,  defenses based on substantial  modification of the product and that
plaintiffs'  injuries  were  caused  by a  superseding,  intervening  cause.  On
November 4, 1996,  the Company  filed a motion for summary  judgment  requesting
that the Court

                                      -22-

<PAGE>



dismiss the plaintiffs'  complaint.  By order dated February 27, 1997, the Court
denied this motion. In doing so, however,  the Court ruled that plaintiffs could
not  proceed  with this  action  under  strict  liability  or  implied  warranty
theories.  Rather,  the  plaintiffs'  case could only proceed under a common law
negligence theory.

         Pursuant to a service  agreement  between MTF and the Company regarding
the  Company's  tissue  processing  services,  the Company has agreed to defend,
indemnify and hold MTF harmless with respect to this action.

         The Company believes that this lawsuit is without merit and the case is
currently being defended, including the defense of MTF, by the Company's product
liability insurance carrier with a general reservation of rights.

Common Stock. The Company believes that there are approximately 2,300 beneficial
owners of its Common Stock.

         The Company 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 the  Company's  growth.  Declaration  of dividends in the
future will remain within the  discretion  of the Company's  Board of Directors,
which will review the Company'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, 1996, 1995 and 1994

Results of Operations

Net Income (Loss)

         In 1996 the  Company  incurred a net loss of  $324,000  compared to net
income of $4,582,000 in 1995 and $1,747,000 in 1994.

         Income before income taxes and unusual items increased to $3,370,000 in
1996 compared to $1,653,000 in 1995 and  $1,212,000 in 1994.  Income,  including
unusual  items and  before  income  taxes was  $2,020,000  in 1996  compared  to
$4,820,000 in 1995 and  $1,212,000  in 1994.  Income before income taxes in 1996
includes a charge to earnings of $1,350,000  related to the restructuring of the
Company's  non-allograft  operations located in Leiden, The Netherlands.  Income
before income taxes in 1995  includes the receipt of note  repayments on a fully
reserved note from a major  customer of  $4,147,000  and a charge to earnings of
$980,000  resulting from the termination of a distribution  agreement for trauma
implant  products.   See  "Provision  for   Restructuring"  and  "Provision  for
Termination of a Distribution Agreement" included elsewhere herein.

         Income tax expense in 1995 and 1994 was reduced by the
recognition of net deferred tax assets resulting primarily from the
realization of tax benefits associated with Federal and state tax
net operating loss carryforwards.  See "Income Tax Provision
(Benefit), net" included elsewhere herein.

         The  following is a discussion  of factors  which  affected  results of
operations for the years ended December 31, 1996, 1995 and 1994.

Net Revenues

         Revenues in 1996 increased 25% to $34,895,000 from $27,934,000 in 1995.
Revenues in 1995 were 14% higher than 1994 revenues of $24,570,000.

         The increase in revenues in 1996 resulted  principally  from  increased
demand for the  Company's  Grafton DBM Gel and the  introduction  of Grafton DBM
Flex in January  1996 and Grafton DBM Putty in November  1996.  The  increase in
revenues in 1995 resulted  principally from increased demand for Grafton DBM Gel
and ceramic hydroxyapatite powders distributed by the Company.

         Supporting the Company's Grafton DBM expansion is a national network of
independent  agencies that manage surgeon  relationships in partnership with the
Company's direct field marketing organization. At December 31, 1996, the network
consisted of 47 agencies with 216  representatives  compared to 27 agencies with
126 representatives at December 31, 1995.

         During 1996, 1995 and 1994, two of the Company's major  customers,  MTF
and ARC, accounted for 64% and 25%, 65% and 20%; and 63% and 22%,  respectively,
of revenues. In December 1996, the Company entered into a new ten-year agreement
with ARC. The Company is currently in negotiations  with MTF for a new agreement
to replace the existing  agreement which expires on March 31, 1997. There can be
no  assurance  that the Company and MTF will enter into a new  agreement or that
such agreement will contain terms  favorable to the Company.  The loss of either
MTF or ARC as a customer would have a material adverse effect on the Company.

Costs of Services and Products

         Costs of services as a percentage of service  revenues was 39% in 1996,
43% in 1995 and 44% in 1994. These declines in costs as a percentage of revenues
result from a shift in revenue mix toward services with higher gross margins and
fixed  processing  costs  being  distributed  over a  higher  volume  of  donors
processed.

         Costs of products as a percentage of product  revenues was 97% in 1996,
77% in 1995 and 67% in 1994.  The increase in costs as a percentage  of revenues
resulted  principally from an increase in product liability  insurance  premiums
associated with spinal implant  products  distributed by the Company pursuant to
an agreement with Ulrich, the manufacturer.

Marketing, General and Administrative Expenses

         Marketing,  general and administrative expenses increased $2,211,000 or
21%  in  1996  and  $817,000  or 9%  in  1995.  These  increases  are  primarily
attributable  to expanded  marketing  activities  associated  with the increased
allograft services provided by the Company, principally those related to Grafton
DBM,  and  increased  facilities'  costs  resulting  from  an  expansion  of the
Company's facilities to support growth.

         Marketing, general and administrative expenses declined as a percentage
of revenues in each year from 39% in 1994 to 37% in 1995 and 36% in 1996.

Research and Development Expenses

         Research and development  expenses in 1996 increased $608,000 or 16% to
$4,357,000  from $3,749,000 in 1995.  Research and development  expenses in 1995
increased  $400,000 or 12% compared to $3,349,000 in 1994. The increases in both
years were primarily  attributable  to increased  spending  associated  with the
development of additional  allograft tissue forms which were introduced into the
market during 1996,  expansion of the Company's viral inactivation  process to a
broader range of allograft tissue and the development of PolyActive(R) products.
See "Provision for Restructuring."

Provision for Restructuring

         In October  1996,  the  Company  announced  a plan to  restructure  its
non-allograft  operations  located in Leiden,  The Netherlands in order to focus
those  operations  on: (i) the  revenue  and  profit  generating  activities  of
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,  the  Company
discontinued  its PolyActive  polymer  research and  development  program.  As a
result of the restructuring, the Company recorded a pre-tax restructuring charge
of $1,350,000,  consisting primarily of employee termination costs, write-off of
equipment,  intangible  assets,  supplies and costs  associated with the planned
sub-leasing  of office  space in Leiden on which  the  Company  has a  long-term
lease. See Note 3 of "Notes to Consolidated Financial Statements."

Provision for Termination of Distribution Agreement

         In June 1995,  the Company  terminated its  distribution  agreement for
trauma implant products with its supplier,  aap, GmbH, of Berlin,  Germany. As a
result of this  termination the Company recorded a pre-tax charge to earnings of
$980,000,  consisting principally of inventory write-offs,  employee termination
costs and legal fees.  The Company has commenced  legal  proceedings  to recover
these costs. Revenues from marketing trauma products were not

material in 1995.  See Note 4 of "Notes to Consolidated Financial
Statements."

Other Income (Expense)

         In 1996, other income decreased by $4,311,000 compared to
1995.  Other income in 1995 included the receipt of $4,147,000 of
note repayments on a fully reserved note from a major customer.
See Note 5 of "Notes to Consolidated Financial Statements."

Income Tax Provision (Benefit), Net

         The income tax provision in each of the years reflects a rate in excess
of the Federal  statutory  income tax rate due to state income taxes and foreign
losses for which no current tax benefits  would be available.  In 1995 and 1994,
the Company  recognized  net deferred tax assets of $2,551,000  and  $2,079,000,
respectively,  resulting  from: (i) the realization of tax benefits of temporary
differences  which reversed during each year  ($1,335,000 in 1995 and $1,479,000
in 1994);  and (ii) the Company's  assessment that it would generate  sufficient
future U.S.  taxable  income to realize a portion of the  deferred  tax benefits
associated with certain Federal and state net operating loss  carryforwards  and
tax credits  ($1,216,000 in 1995 and $600,000 in 1994). See Note 13 of "Notes to
Consolidated Financial Statements."

Liquidity and Capital Resources

         At December 31, 1996, the Company had cash and  short-term  investments
of  $9,277,000  compared to  $7,707,000  at December 31, 1995.  Working  capital
increased  $138,000 to  $12,273,000 at December 31, 1996 compared to $12,135,000
at December 31, 1995.

         The Company has 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, 1996,  $1,377,000
was outstanding  under the equipment line of credit and there were no borrowings
outstanding  under the revolving line of credit.  The Company also has a line of
credit with a Dutch bank which  provides for  borrowings of up to 5,000,000 dfl,
or approximately  $2,872,000 at the December 31, 1996 exchange rate. Analysis of
the Company's  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 1996 and,  therefore,  the  Company  agreed with the bank to limit its
borrowings  in 1996,  if any, to no more than  3,000,000  dfl, or  approximately
$1,723,000 at the December 31, 1996 exchange rate.  Additionally,  in connection
with the Leiden facility lease,  the Company is required to maintain a declining
bank  guarantee  which reduced the current  amount  available for  borrowings to
2,424,000  dfl, or  approximately  $1,392,000  at the December 31, 1996 exchange
rate. At December 31, 1996, there were no borrowings outstanding

                                      -29-

under this credit line.  See Note 11 of "Notes to Consolidated
Financial Statements."

         At  December  31,  1996,  the  Company  had  U.S.  net  operating  loss
carryforwards  which approximate  $1,099,000 for Federal income tax purposes and
$216,000 for state income tax purposes. The Federal and state net operating loss
carryforwards,  if unused,  will expire from 2006 through 2011. The Company also
has  research  and  development  tax credits for Federal  income tax purposes of
$11,000  which  expire  in 2009.  The  timing  and  manner in which the tax loss
carryforwards  and credits are utilized in the future may be limited by Internal
Revenue Code Section 382. In  addition,  certain of the  Company's  subsidiaries
have foreign net operating loss carryforwards  aggregating $10,041,000 ($350,000
with no expiration date;  $9,691,000 expiring 1999 through 2004). See Note 13 of
"Notes to Consolidated Financial Statements."

         During 1996 the Company incurred capital  expenditures of $2,152,000 to
support the expansion of the Company's  operations.  Although the Company had no
significant  commitments  for capital  expenditures  as of December 31, 1996, it
expects 1997 capital  expenditures to be approximately  50% higher than those of
1996. It is expected that these  expenditures will be funded from cash reserves,
cash provided by operations or bank financing.

         The Company  believes  that its cash and cash  equivalents,  short-term
investments and available lines of credit,  together with  anticipated cash flow
from operations will be sufficient to meet its near-term  requirements,  but may
not be adequate to fully develop and commercialize all products  currently under
development  by the Company.  Further,  from time to time,  the Company may seek
additional  funds through  equity or debt  financing.  However,  there can be no
assurance  that such  additional  funds will be available to the Company,  or if
available, that such funds will be available on terms favorable to the Company.

                        REPORT OF INDEPENDENT ACCOUNTANTS







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




We have audited the accompanying  consolidated balance sheets of Osteotech, Inc.
and  Subsidiaries as of December 31, 1996 and 1995 and the related  consolidated
statements of  operations,  changes in  stockholders'  equity and cash flows for
each of the three years in the period ended December 31, 1996.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all  material  respects,  the  consolidated  financial  position  of
Osteotech,  Inc.  and  Subsidiaries  as of December  31, 1996 and 1995,  and the
consolidated  results of its operations and its cash flows for each of the three
years in the period ended  December  31,  1996,  in  conformity  with  generally
accepted accounting principles.

1.   DESCRIPTION OF BUSINESS

     Osteotech,  Inc. (the  "Company"),  formed in 1986,  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: (i) the processing of
     human  bone,  ligaments  and  tendons  (collectively,  "bone  tissue")  for
     transplantation;  (ii)  providing  ceramic  (hydroxyapatite)  and  titanium
     plasma  spray  coating   services  and  ceramic   based   products  to  the
     orthopaedic,  dental and ear, nose and throat  implant  markets;  and (iii)
     distributing  implant  devices  and  specialized   instruments  for  spinal
     surgery.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Consolidated Financial Statements
     The consolidated financial statements include the accounts of Osteotech,
     Inc. and its majority-owned subsidiaries. All intercompany transactions and
     balances are eliminated in consolidation.

     Revenue Recognition
     Revenue is  recognized at the time the Company  provides  services or ships
     products to its customers.

     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 bone tissue  processing  in progress are  deferred  until
     processed bone tissue is released from final quality assurance testing.

     Equipment and leasehold  improvements  are stated at cost less  accumulated
     depreciation   and   amortization.   Depreciation   is   computed   on  the
     straight-line  method over the  estimated  useful lives of the assets which
     range  from  three to ten  years.  The cost of  leasehold  improvements  is
     amortized on the straight-line method over the shorter of the lease term or
     the estimated useful life of the asset.  Major renewals and betterments are
     capitalized.  Maintenance  and  repairs  are  expensed  as  incurred.  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 a
     permanent  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  accumulated  as a separate  component of
     stockholders'  equity.  Foreign currency  transaction  gains and losses are
     included in other income.

     Net Income (Loss) Per Share
     The  computation  of net income  (loss) per share is based on the  weighted
     average  number of common  shares and nominal  warrants  (warrants  with an
     exercise  price  of $.03)  outstanding  adjusted  to  reflect  the  assumed
     exercise of outstanding stock options and other warrants using the treasury
     stock  method  to the  extent  these  items  had a  dilutive  effect on the
     computations.

     Income Taxes
     The Company follows  Statement of Financial  Accounting  Standards No. 109,
     Accounting  for Income  Taxes ("SFAS 109") which  requires  recognition  of
     deferred  tax assets  and  liabilities  based on  differences  between  the
     financial statement carrying amounts of existing assets and liabilities and
     their respective tax bases,  measured using the enacted tax rates in effect
     for the years in which the  differences  are  expected to be  recovered  or
     settled.

     Concentrations of Credit Risk
     The Company  provides credit,  in the normal course of business,  to tissue
     banks, hospitals and Company agents. 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.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

     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.


3.   RESTRUCTURING OF THE NETHERLANDS OPERATIONS

     In  October  1996,  the  Company   announced  a  plan  to  restructure  its
     non-allograft operations located in Leiden, The Netherlands.  In connection
     with the restructuring, the Company discontinued its PolyActive(TM) polymer
     research and development  program.  As a result of the  restructuring,  the
     Company recorded a pre-tax  restructuring charge of $1,350,000,  consisting
     primarily of employee termination costs, write-off of equipment, intangible
     assets,  supplies  and costs  associated  with the planned  sub-leasing  of
     office space in Leiden on which the Company has a long-term lease.


4.   TERMINATION OF DISTRIBUTION AGREEMENT

     In June 1995, the Company terminated its distribution  agreement for trauma
     implant  products with its supplier,  aap,  GmbH of Berlin,  Germany.  As a
     result of this  termination,  the  Company  recorded  a  pre-tax  charge to
     earnings  of  $980,000  consisting  principally  of  inventory  write-offs,
     employee termination costs and legal fees.


5.   NOTE RECEIVABLE FROM A MAJOR CUSTOMER

      The Company is the exclusive  processor of allograft bone tissue  procured
      and distributed by the Musculoskeletal Transplant Foundation ("MTF"). (See
      Note 8 and Note 16.) From MTF's  inception  in February  1987  through May
      1989, the Company  supplemented MTF's working capital requirements through
      a series of cash advances and unpaid  processing and service fees. In June
      1990,  the principal  and interest on these  advances at December 31, 1989
      were converted into two notes which were fully reserved by the Company.

      The first note had an original face value of  $7,216,000.  During 1995 the
      Company  received  $4,147,000 of principal  payments on this note reducing
      the  outstanding  balance  to $0.  During  1994 the  Company  received  no
      principal  payments on this note.  During  1995 and 1994 the Company  also
      received interest payments from MTF on this note of $330,000 and $285,000,
      respectively.

5.   NOTE RECEIVABLE FROM A MAJOR CUSTOMER (continued)

     The  second  note,   with  an  original  face  value  of  $2,621,000,   was
     non-interest  bearing and was subject to cancellation by the Company at the
     rate of  $524,000  per year on the  anniversary  of the note  (June  30th),
     provided MTF met certain annual requirements as defined in the note. During
     1995,  the Company  canceled  $524,000  of the note  thereby  reducing  the
     remaining amount  outstanding to $0. The Company also canceled  $524,000 of
     the note on June 30, 1994.  The  cancellation  of the note had no impact on
     the Company's results of operations since the note was fully reserved.

8.   COMMITMENTS AND CONTINGENCIES

     Service Agreements
     Osteotech is the  exclusive  processor  of allograft  bone tissue for large
     national  and  international  not-for-profit  organizations.   The  Company
     provides  these   processing   services   pursuant  to  long-term   service
     agreements.  Customers  are  charged  fees  on a per  donor  basis,  or for
     proprietary

8.   COMMITMENTS AND CONTINGENCIES (continued)

     products on a per unit basis,  for direct and indirect  processing  and for
     finishing  and  packaging  each unit of bone tissue  produced.  Osteotech's
     agreements  with  its  customers  generally  provide  for  the  Company  to
     indemnify  its  customers  against  liability  arising  out of  defects  in
     allograft  bone tissue caused as a result of processing by the Company.  In
     December 1996,  the Company  entered into a new ten year agreement with one
     of its major  customers,  the  American Red Cross  ("ARC").  The Company is
     currently in discussions with its other major customer,  MTF, to enter into
     a new long-term  agreement to replace the existing  agreement which expires
     on March 31, 1997.  There can be no assurance that the Company and MTF will
     enter  into a new  agreement  or that such  agreement  will  contain  terms
     favorable to the Company. (See Note 16.)

     Customers of the Company's plasma spray coating services generally purchase
     such  services   pursuant  to  purchase  orders  or  non-exclusive   supply
     agreements which are cancelable at any time by either party.

     Litigation
     The Company has been named as a defendant  in a number of lawsuits in which
     patients  claim that they have suffered  damages from the  implantation  of
     allegedly  defective spinal fixation devices  allegedly  distributed by the
     Company.  Management  believes  that the suits and claims are without merit
     and intends 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  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 or willful  misconduct or unauthorized claim
     made by the Company in marketing  the  products.  In  connection  with this
     indemnification,  the  Company  received  $59,000  from  Ulrich  in 1996 as
     reimbursement for legal costs incurred by the Company.

     The Company has also been named as a defendant in a lawsuit  which  alleges
     that the Company and co-defendant MTF mislabeled and mispackaged  processed
     human bone  tissue.  Pursuant  to a service  agreement  between MTF and the
     Company regarding the Company's tissue processing services, the Company has
     agreed to defend,  indemnify  and hold  harmless  MTF with  respect to this
     action. Management believes that this lawsuit is without merit and the case
     is currently being defended, including the defense of MTF, by the Company's
     products liability insurance carrier.

     The Company maintains products  liability  insurance coverage in the amount
     of $20 million per occurrence and per year in the aggregate, however, there
     can be no  assurance  that these  claims  will be covered by the  Company's
     insurance  policy.  Management  is unable to  predict  the  outcome  of the
     pending suits and claims or whether or not their ultimate  disposition will
     have a material effect upon the consolidated financial position, results of
     operations and liquidity of the Company.

9. LEASING TRANSACTIONS

     The Company  leases office and production  facilities  and equipment  under
     various capital and operating lease  agreements  which have  non-cancelable
     terms  through May 2008.  The leases for office and  production  facilities
     include renewal provisions at the Company's option.  Additionally,  certain
     of the leases contain purchase options.

     Future minimum lease commitments as of December 31, 1996 are as follows:

10.   STOCKHOLDERS' EQUITY

     Preferred Stock

     In July 1991, upon completion of the Company's initial public offering, the
     authorized  capital of the Company was amended to reflect  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, 1996 and 1995.

     Stock Options

     The Company has two stock  option  plans  currently  in effect  under which
     future  grants may be issued:  the 1991 Stock Option Plan (the "1991 Plan")
     and the 1991  Independent  Directors  Stock  Option  Plan  (the  "Directors
     Plan").  These  plans,  as  amended,  provide  for  the  issuance  of up to
     1,813,765 and 500,000 shares respectively, of the Company's Common Stock.

     The 1991 Plan  provides  for  option  grants  to  officers,  employees  and
     consultants  designated as either non-qualified or incentive stock options.
     The  Directors  Plan  provides for option grants to members of the Board of
     Directors  who are not officers or employees of the Company.  The Directors
     Plan is a non-statutory  stock option plan covering the issuance of options
     that will not qualify as incentive stock options.  Options generally become
     exercisable in ratable installments over a four-year period.

10.   STOCKHOLDERS' EQUITY (continued)

     Prior to the  adoption  of the 1991 Plan,  the  Company  issued  options to
     officers,  employees and consultants  pursuant to written option agreements
     which were not subject to a formal plan. The option price was  periodically
     set by the Board of Directors  based upon an  evaluation of the fair market
     value of the Company's  Common Stock.  Options  issued  pursuant to written
     option agreements generally became exercisable in ratable installments over
     a four-year  period.  The Company no longer issues options not covered by a
     formal plan.  At December 31,  1996,  the Company  reserved an aggregate of
     42,391  shares of its Common  Stock for issuance  upon  exercise of options
     granted pursuant to written option agreements.

     Stock option activity for the years 1996, 1995 and 1994 is as follows:

     In April 1995,  the Company  instituted  a stock  option  exchange  program
     whereby  optionees  with options  having an exercise price of $6.00 or more
     were offered  repriced  options on the basis of a 65% exchange  ratio.  The
     exercise price of the new options was the then current fair market value of
     the Common  Stock  which was $5.25 per share.  As a result of the  exchange
     program,  options for 327,458  shares were canceled and options for 213,477
     shares were issued.

     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 and net income 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.  The Company's pro forma  information  follows (in
     thousands except for per share information):

     The pro forma effect on net income for 1995 and 1996 is not  representative
     of the pro forma effect on net income in future  years  because it does not
     take into  consideration pro forma  compensation  expense related to grants
     made prior to 1995.

     Convertible  Preferred  Stock  warrants are  immediately  convertible  into
     Common Stock upon exercise on a share for share basis. In January 1994, the
     Board of Directors approved amending all outstanding  warrants to allow for
     cashless exercise of such warrants. 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
     250,000 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 31,1996,  198,438 shares were available for future offerings under
     this plan.

     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, 1996 and
     1995,  $1,377,000 and $2,080,000,  respectively,  was outstanding under the
     equipment  line of credit and there were no borrowings  under the revolving
     line of credit.

11. DEBT AND FINANCING ARRANGEMENTS (continued)

     The  Company  has a line of credit  with a Dutch  bank which  provides  for
     borrowing up to 5,000,000 dfl, or approximately  $2,872,000 at the December
     31, 1996 exchange rate.  Borrowings under this credit line bear interest at
     the Dutch Central Bank discount rate for promissory  notes plus a margin of
     2.5%. Under certain  circumstances  the Company may elect to utilize a rate
     based on the Amsterdam  Interbank Offered Rate (AIBOR) plus a margin of 1%.
     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 1996 and,  therefore,  the
     Company agreed with the bank to limit its borrowings in 1996, if any, to be
     no more than 3,000,000 dfl, or approximately $1,723,000 at the December 31,
     1996 exchange rate.  Additionally,  in connection  with the Leiden facility
     lease, the Company is required to maintain a declining bank guarantee which
     reduced the current  amount  available  for  borrowings to 2,424,000 dfl or
     approximately  $1,392,000  at the  December  31,  1996  exchange  rate.  At
     December  31, 1996 and 1995,  there were no  borrowings  under this line of
     credit.

     The weighted average interest rate on short-term notes payable  outstanding
     was 5.87% in 1996 and 5.73% in 1995.

     Loss before income taxes from foreign  operations  was  $3,652,000 in 1996,
     $1,910,000 in 1995 and $1,839,000 in 1994, respectively.  The components of
     the  deferred tax assets and  deferred  tax  liabilities  are as follows at

        ===========================================================  ==========


     In 1996,  the Company  increased  its  valuation  allowance  as a result of
     foreign  losses  for  which  the  realization  of future  tax  benefits  is
     uncertain.  In 1995 and 1994 the Company  reduced its  valuation  allowance
     resulting in the  recognition  of net deferred tax assets of $2,551,000 and
     $2,079,000,  respectively,  resulting  from  (i)  the  realization  of  tax
     benefits  of  temporary   differences   which  reversed  during  each  year
     ($1,335,000  in 1995 and  $1,479,000  in  1994);  and  (ii)  the  Company's
     assessment that it would generate  sufficient future U.S. taxable income to
     realize a portion of the  deferred  tax  benefits  associated  with certain
     Federal  and  state  net  operating  loss  carryforwards  and  tax  credits
     ($1,216,000 in 1995 and $600,000 in 1994).

     At December 31, 1996, the Company had U.S. net operating loss carryforwards
     which  approximate  $1,099,000 for Federal income tax purposes and $216,000
     for state income tax  purposes.  The Federal and state net  operating  loss
     carryforwards,  if unused,  expire from 2006 through 2011. The Company also
     has research and  development tax credit  carryforwards  for Federal income
     tax purposes of  approximately  $11,000  which expire 2009.  The timing and
     manner in which the U.S. net operating loss  carryforwards  and credits are
     utilized in the future may be limited by Internal Revenue Code Section 382.
     In  addition,  certain  of the  Company's  subsidiaries  have  foreign  net
     operating  loss  carryforwards  aggregating  $10,041,000  ($350,000 with no
     expiration date; $9,691,000 expiring 1999 through 2004).

     Approximately  $214,000  of  the  net  operating  loss  carryforwards  were
     acquired in connection  with the acquisition of HC Implants BV in May 1992.
     Subsequently  recognized tax benefits which result from the  utilization of
     these acquired net operating loss  carryforwards  will be applied to reduce
     the excess of cost over net assets of business acquired.

1.       PROCESSING
1.1      Bone and Related Tissues Supplied by ARC
1.1.1             General Undertaking.  ARC shall supply all Tissue that it
                  procures exclusively to Osteotech for Processing.  Tissue
                  utilized in ARC research and development activities, if
                  any, shall be excluded from this requirement.  At Osteotech's
                  request, each month ARC shall use its best efforts to provide
                  to Osteotech for Processing sufficient cortical bone tissue to
                  be processed into Grafton(R)products in order to meet
                  hospital/end user market demand for such products. The Tissue
                  shall be delivered to Osteotech, at ARC's expense, and shall
                  conform to all standards, guidelines, rules, regulations and
                  laws of (i) the United States Food and Drug administration
                  (FDA); (ii) the American Association of Tissue Banks (AATB);
                  (iii) other applicable U.S. federal, state and local
                  government agencies; (iv) any non-U.S. jurisdiction where
                  Tissue may be procured or distributed by or on behalf of ARC;
                  (v) ARC's standard operating procedures ("SOPs") as may be
                  amended from time to time by ARC; and (vi) Osteotech's
                  processing standards as specified in Osteotech's SOPs as may
                  be amended from time to time by Osteotech.  All of such
                  standards, guidelines, rules, regulations, laws, procedures
                  and standards are hereinafter referred to as the "Processing
                  Standards."  If interpretation of the Processing Standards is
                  required or if there is a disagreement about the
                  interpretation of the Processing Standards, ARC and Osteotech
                  will negotiate in good faith a resolution within thirty (30)
                  days.  If there is a conflict between ARC's SOPs and
                  Osteotech's SOPs, ARC and Osteotech will negotiate in good
                  faith a resolution within thirty (30) days.  If the issues
                  covered by the preceding two sentences are not resolved within
                  such thirty (30) day period, the parties will mutually agree
                  to a third party who will assist the parties in arriving at a
                  resolution.  Recovery Standards shall mean all laws,
                  standards, rules, regulations, procedures and guidelines

                  related   to   the   donation,    recovery   and   suitability
                  determination  of Tissue,  including donor referral,  informed
                  consent, tissue recovery,  pre-processing  storage,  packaging
                  and shipping and all records, activities and standards related
                  to obtaining,  testing, documenting and evaluating serological
                  test results;  obtaining,  documenting and evaluating  medical
                  history  and  lifestyle  data;  and  related   organizational,
                  management and quality assurance activities.

         ARC and  Osteotech  shall  provide  each  other a copy of its  SOPs and
         copies of any amendments to its SOPs promptly after such amendments are
         adopted;  provided,  however, that doing so will not require such party
         to  disclose  any  trade  secrets,  technical  know how or  unpublished
         scientific data or technical art. Upon reasonable notice and at its own
         expense,  each of Osteotech  and ARC shall have the right to conduct an
         annual audit of the other  party's  facilities  and records  related to
         regulatory  compliance.  Upon reasonable notice and at its own expense,
         each of  Osteotech  and ARC shall have the right to conduct  additional
         audits  of  the  other  party's   facilities  and  records  related  to
         regulatory  compliance  in the  event  there are  repeated  significant
         defects in such other party's SOPs, or in such other party's compliance
         with its SOPs or any applicable Processing Standards.

1.1.2             Volume
         (a)      ARC shall procure, store and distribute all Tissue in a manner
                  that  assures  that such Tissue will  conform to the  Recovery
                  Standards and the Processing Standards,  and shall deliver all
                  such Tissue to Osteotech.
         (b)      ARC may increase  the volume of donors  delivered to Osteotech
                  above the volume set forth in the applicable forecast prepared
                  and agreed to in accordance with subsection (c), provided that
                  it gives Osteotech 90 days

                                       E-4

<PAGE>



                  prior written notice for every planned incremental increase of
                  50  donors,  unless  Osteotech  agrees in writing to a shorter
                  notice period for any of these increases.
         (c)      Subject to subsection (b), during the term of this
                  Agreement, ARC and Osteotech shall jointly agree upon
                  written forecasts for the Processing of Tissue for the
                  succeeding six months, broken out by month.  The first
                  such forecast shall be provided 30 days after the
                  effective date of this Agreement; each such forecast
                  shall be a rolling six month forecast provided each
                  January 1, April 1, July 1 and October 1.  If the parties
                  cannot agree upon a forecast for any month, the forecast
                  for such month shall be the average of the forecasts of
                  the parties for the immediately preceding three months.
         (d)      Osteotech  will arrange  with ARC to hold  regular  production
                  meetings to discuss the forecasts and other processing issues.

1.1.3             Donor Records
         ARC will obtain and maintain all  necessary  books,  records,  and data

         on the  Tissue  procurement  activity  of  ARC  occurring  during  that
         quarter.  Osteotech shall have the right to audit ARC Tissue donor data
         upon reasonable prior written notice to ARC.

         ARC shall  also  obtain  and  forward  to the  requesting  governmental
         regulatory agency, in English, such records,

                  necessary to prepare procured Tissue for transplantation.
         (b)      Osteotech  shall,  upon  reasonable  prior written notice from
                  ARC,  permit  ARC to change  the  production  plan for a donor
                  determined pursuant to Section 1.2.3(a).

1.2.2             Processes and Methods
         (a)      Processing of Tissue will be performed by Osteotech under
                  applicable Processing Standards.
         (b)      In the event the FDA implements new or additional  regulations
                  applicable to Tissue,  Osteotech and ARC shall each  implement
                  such changes to its SOPs as are  necessary to comply with such
                  FDA regulations. In the event Osteotech is unable or unwilling
                  to implement such changes, ARC shall have the remedy set forth
                  in Section 6.5.
         (c)      Osteotech will grant  designated  ARC personnel  access to its
                  facilities to observe all steps of Processing  for the purpose
                  of  conducting a standard  ARC  inspection  of the  Processing
                  Standards.   As  part  of  this  inspection,   all  Processing
                  Standards  will be made available to the  inspectors.  If such
                  personnel  require  access  to  Osteotech's  cleanrooms,   the
                  personnel must have on file

                                       E-6

<PAGE>



                  with Osteotech  appropriate  blood serum test results and such
                  other tests as Osteotech may require  prior to such  personnel
                  being granted access to Osteotech's cleanrooms. Osteotech may,
                  at its  sole  discretion,  refuse  any  individual  access  to
                  Osteotech cleanrooms for cause. Such denial of access will not
                  be a violation of this Agreement.

1.2.3             Processing Considerations:
         (a)      ARC will pre-plan, which will include a written primary
                  and secondary donor plan, the expected production from
                  each donor prior to the scheduled day of processing.  If
                  Tissue cannot be processed according to either the
                  primary or secondary donor plan, verbal approval will
                  first be obtained from the procuring ARC Area for changes
                  to the primary or secondary donor plan prior to
                  processing by Osteotech and ARC will confirm by faxed
                  written approval.  Osteotech will use its best efforts to
                  maximize the planned yield from each donor.
         (b)      Osteotech may present valid evidence to ARC if Osteotech
                  determines that FDA, AATB or other applicable government
                  agency mandated changes in processing techniques or the
                  quality and condition of ARC donor Tissue prevents the
                  achievement of the planned yield provided for in
                  Subsection (a).  The parties agree to discuss the
                  implications of such parameters and to determine a
                  reasonable yield based on such new requirements.

         (c)      ARC shall undertake reasonable efforts to present a consistent
                  flow of  donors  to  Osteotech  with  the  goal of  minimizing
                  end-of-month  bunching of donors.  Subject to the  foregoing
                  sentence,  donors received at Osteotech for Processing will be
                  processed  within a  reasonable  period  of time from the time
                  (which  shall be reviewed at the regular  production  meetings
                  provided for in Section

                                       E-7

                  1.1.2(d))  (i) all related  required  donor  documentation  is
                  received  at  Osteotech,  (ii)  such  documentation  has  been
                  reviewed by Osteotech's  Quality  Assurance  Department and/or
                  Regulatory Affairs Department and (iii) such documentation has
                  been found by such department or departments,  as the case may
                  be, to be complete in every respect and to otherwise  meet the
                  requirements of the Processing  Standards.  Once Processing of
                  the donor is complete,  subject to the  provisions of Sections
                  2.1.1 and  2.1.3(a),  all  Tissue  will be shipped to ARC upon
                  final  inspection and release  thereof by Osteotech's  Quality
                  Assurance Department.

         (d)      If the release of processed  Tissue back to ARC is delayed due
                  to: (i) Tissue histology of unknown etiology or (ii) microbial
                  contamination  of final product,  Osteotech  will  immediately
                  notify the  procuring  ARC area of the reason for the hold and
                  the approximate time period expected for the hold (in weeks).

2.1.2    Storage
         (a)      Osteotech shall, at ARC's election,  store ARC Allograft units
                  released by Osteotech awaiting shipment. Such storage shall be
                  in compliance  with all applicable  portions of the Processing
                  Standards.

         (b)      In the event that Tissue which is being processed by
                  Osteotech or held by Osteotech in "quarantine storage",
                  "pre-processing storage", or "post-processing storage"
                  (as such terms are defined or described in the applicable
                  portions of the Processing Standards) is destroyed or
                  rendered unusable while in the possession of Osteotech
                  due to the negligence of Osteotech, Osteotech shall pay
                  to ARC any costs incurred by ARC in procuring and
                  transporting such Tissue to Osteotech.

2.1.3    Shipping
         (a)      Except as otherwise provided in a written document signed
                  by both Osteotech and ARC, Osteotech shall ship all
                  finished units of Tissue, other than demineralized bone
                  and items being reworked, derived from a donor received
                  for Processing from a Red Cross Area back to that Area in
                  one shipment by a carrier designated by ARC.  Osteotech
                  shall ship finished units of demineralized bone to either
                  the Red Cross Area from which the donor was received or
                  as directed by ARC.  All items being reworked will be
                  shipped back to the Red Cross Area from which the donor
                  was received as soon as it is completed and released by
                  Osteotech's Quality Assurance Department.  ARC shall be
                  responsible for payment of all shipping costs.

         (b)      Osteotech  shall ship all finished units of Tissue in shipping
                  containers  which  meet  the  requirements  specified  in  the
                  Processing  Standards.  All packaging and shipping  containers
                  must  be  validated  and  the  validation   studies  shall  be
                  available for review by ARC's Quality Assurance and Regulatory
                  Affairs Departments.

         (c)      Osteotech  shall  clearly  label each  shipping  container  as
                  containing  transplantable  tissue and with the  addresses  of
                  both the shipping and receiving facility.  Such labeling shall
                  meet the specifications included in the Processing Standards.

         (d)      Each shipment from  Osteotech  shall include a packaging  slip
                  listing the  contents  and  corresponding  donor lot and batch
                  numbers, if applicable. All tissue containers in each shipment
                  shall be packed with sufficient  materials between  containers
                  so that breakage will be minimized.

         (e)      ARC will promptly notify Osteotech of any damage to the
                  finished units of Tissue during shipment thereof.
                  Osteotech will file a claim against the shipping carrier
                  for the amount of damage up to ARC's property insurance
                  deductible, currently $25,000.  ARC will notify Osteotech
                  of any changes to this property insurance deductible
                  amount during the term of this agreement.  Osteotech will
                  be responsible to request that coverage of this amount be
                  provided by the shipping carrier at ARC's cost.  The
                  amount recovered from the shipping carrier for claims
                  will be passed on to ARC within 10 days of receipt by
                  Osteotech.  Osteotech shall have no liability for any
                  damage to finished Tissue incurred during shipping,
                  except to the extent Osteotech fails to ensure that the
                  shipping carrier has the aforementioned insurance.

         (d)      All labeling will be in accordance with Sections
                  2.1.3(b), 2.1.3(c) and 2.1.4(a), and the Processing
                  Standards.

         (e)      Specifications for all Tissue products to be processed
                  from ARC donors will be developed and approved according
                  to ARC and Osteotech SOPs.  Requests to Osteotech about
                  its ability to accomplish special specifications will be
                  made in writing by ARC and will receive a written
                  response from Osteotech within a reasonable period of
                  time.  Requests by ARC for labeling changes, including
                  package inserts, will be responded to by Osteotech in
                  writing within 10 working days indicating its ability to
                  accomplish the changes.

2.2      Liability
         (a)      Osteotech agrees to defend, hold harmless, and indemnify
                  ARC against any liability in respect of bodily injury,
                  death, and property damage arising from the negligence or
                  willful misconduct of Osteotech or its directors,
                  officers, employees and agents in the performance of

                  in any finished unit of Tissue processed by Osteotech
                  under this agreement, to the extent such defect results
                  from an error or omission, or from a failure of
                  workmanship, by Osteotech.

         (b)      ARC agrees to defend,  hold harmless,  and indemnify Osteotech
                  against any liability in respect of bodily injury,  death, and
                  property   damage  arising  from  the  negligence  or  willful
                  misconduct of ARC or its directors,

                  the "indemnifying party" and ARC shall be the
                  "indemnified party" and for the purposes of subsection
                  (b) above, ARC shall be the "indemnifying party" and
                  Osteotech shall be the "indemnified party".  The
                  obligations and liabilities of the indemnifying party
                  hereunder with respect to claims resulting from the
                  assertion of liability by third parties shall be subject
                  to the following terms and conditions:

                  (i)      The indemnified party shall give written notice to
                           the indemnifying party of any assertion of
                           liability by a third party which might give rise to
                           a claim by the indemnified party against the
                           indemnifying party based on the indemnity contained
                           in Section 2.2(a) hereof, or Section 2.2(b) hereof,

                           or receiving notice thereof.

                  (ii)     In the  event  any  action,  suit  or  proceeding  is
                           brought against the indemnified  party,  with respect
                           to which the  indemnifying  party may have  liability
                           under the indemnity agreement contained in subsection
                           (a) hereof,  the action,  suit or  proceeding  shall,
                           upon the written agreement of the indemnifying  party
                           that it is obligated to

                           indemnified  party and its attorneys and  accountants
                           all  books  and  records  of the  indemnifying  party
                           relating  to  such  proceedings  or  litigation.  The
                           parties will render to each other such  assistance as
                           they may  reasonably  require  in order to ensure the
                           proper and adequate defense of any such action,  suit
                           or proceeding.

               (iii)       The  indemnifying  party  shall  not make any
                           settlement  of any  claims without the  written  
                           consent of the indemnified   party,  which  consent
                           shall not be  unreasonably  withheld or delayed.

                (iv)       The indemnified party shall not make any settlement
                           of any claims without the written consent of the
                           indemnifying party.

         (d)      The provisions of Section 2.2 shall survive termination
                  of this Agreement.

2.3      Records and Reports
         (a)      Osteotech  shall maintain on a daily basis,  accurate  records
                  concerning Tissue received, Tissue processed and in storage at
                  Osteotech and finished units of Tissue

                  during normal business hours upon reasonable advance notice at
                  ARC's expense.  Osteotech shall not be required to produce any
                  data  other  than data  which it is  required  to  obtain  and
                  maintain by the Processing Standards.

         (b)      In addition  to the  information  provided  in (a),  Osteotech
                  shall  provide  timely  reports on each donor  showing  Tissue
                  processed and shipped.  Reports at the time of shipping should
                  include total  disposition of all Tissue,  including  cortical
                  storage, pending reworks and discards.

         (c)      Osteotech shall ensure that all information  pertaining to ARC
                  will be disclosed  only to those  Osteotech  personnel  with a
                  need-to-know    who   have   signed    Osteotech's    standard
                  confidentiality agreement.

         (d)      Osteotech  shall  notify  ARC prior to the  release of any ARC
                  donor  identifying  information,  such  as  donor  identifying
                  number,  whether  pursuant  to  request  of  a  regulatory  or
                  governmental  agency  or  court  or  administrative  order  or
                  subpoena.  The  provisions  of this  subsection  shall survive
                  termination of this Agreement.

         (e)      Osteotech shall provide ARC monthly written reports to
                  include:
                  Rework status, cause, projected release date and trend
                  analysis;

2.4      New Product Development
         It is the understanding of ARC and Osteotech that each of them
         may independently develop new products and/or processes or
         improve upon existing products and/or processes.  Therefore,

         (a)      Subject to  subsection  (c),  Osteotech  shall own all rights,
                  title  and  interest  in and to all  information,  technology,
                  data, inventions,  products, and processes, conceived, made or
                  developed   by   employees   of   Osteotech  as  well  as  the
                  intellectual property rights based thereon,  including but not
                  limited to copyrights and patent rights.

         (b)      Subject to subsection (c), ARC shall own all rights, title and
                  interest  in  and  to  all  information,   technology,   data,
                  inventions,   products,  and  processes,  conceived,  made  or
                  developed  by  employees  of ARC as well  as the  intellectual
                  property  rights based  thereon,  including but not limited to
                  copyrights and patent rights.

         (c)      Any  joint  development  of  information,   technology,  data,
                  inventions,   products,  and  processes,  shall  be  conducted
                  pursuant to a formal written  development  agreement signed by
                  Osteotech  and ARC and a  development  budget for the  project
                  agreed to in writing by Osteotech and ARC.

         (d)      The provisions of this Section 2.4 shall survive
                  termination of this Agreement.

2.5      Non-Proprietary New Products
         It is understood and agreed that Osteotech may develop new information,
         technology,  data, inventions,  products, and processes  (collectively,
         "new  products")  jointly with its other  customers and that certain of
         such new products may not be subject to patent or copyright  protection
         ("non-proprietary  new  products").  ARC agrees  that it shall not have
         access to, or utilize,  such non-proprietary new products and shall not
         be able to cause Osteotech to utilize such non-proprietary new products
         on ARC's behalf unless and until ARC shall reimburse Osteotech and such
         other client for one-third (in the aggregate) of the development  costs
         (including  without  limitation  internal  direct costs,  but excluding
         internal  overhead  costs)  for such  non-proprietary  new  product  as
         reasonably  determined  by Osteotech  and such client.  The methods and
         bases for determining such development  costs shall be disclosed to ARC
         on a confidential basis.  Osteotech shall include a provision identical
         in substance to the  foregoing  provision  in its  agreements  with its
         other significant  customers to cover any  non-proprietary new products
         which may be developed jointly hereunder by Osteotech and ARC.

2.6      Shipment of Finished Units and Marketing and Education
         Services
         (a)      At the request of ARC, Osteotech will ship finished units
                  of  Tissue to end user  customers  of ARC in  accordance  with
                  procedures   and   protocols   established   between  ARC  and
                  Osteotech.  Fees for such services will be  established at the
                  time such  services are  requested  and are separate  from the
                  fees listed in Exhibits 3.1 and 3.2.  Fees for these  services
                  may be changed from time to time to

                                      E-17

<PAGE>



                  reflect changes in services being performed or in the
                  cost of performing these services.

         (b)      Osteotech shall provide marketing and education services
                  in accordance with protocols and procedures established
                  between ARC and Osteotech and outlined in Exhibit 2.6.
                  It is anticipated that the level of such services shall
                  be at least equal to those provided by Osteotech during
                  the year ended December 31, 1996.  It is anticipated that
                  Osteotech will not charge ARC a fee for such services,
                  provided that Osteotech reserves the right to charge a
                  fee, to be agreed upon by Osteotech and ARC, if the scope
                  or level of such marketing and education services are
                  materially changed or if Osteotech otherwise determines
                  that it cannot provide such services on a cost effective
                  basis.  If fees are charged for such services such fees
                  will be separate from the fees listed in Exhibits 3.1 and
                  3.2.

         (c)      Osteotech may provide such other services as are
                  requested by ARC in accordance with protocols and
                  procedures established between ARC and Osteotech.  Fees
                  for such services will be established at the time such
                  services are requested and will be separate from the fees
                  listed in Exhibits 3.1 and 3.2.  Fees for these services
                  may be changed from time to time to reflect changes in
                  services being performed or in the cost of performing
                  these services.

2.7      Publication and Public Disclosure
         (a)      ARC shall  have the right to  publish  or  otherwise  publicly
                  disclose  scientific  information  or data developed by ARC at
                  its own  expense  which  utilizes  or relates  to  Osteotech's
                  Processing technology, provided, however, that notwithstanding
                  any other provision in this

                                      E-18

<PAGE>



                  Agreement to the contrary,  no such  publication or disclosure
                  shall be made by ARC if such  publication or disclosure  would
                  result  in  the   disclosure   of   information   defined   as
                  confidential  in  Section  4 or  would  otherwise  violate  or
                  jeopardize  any  proprietary  rights  Osteotech  may have with
                  respect to such technology.  Publication of jointly  developed
                  information will be covered in a separate agreement.

         (b)      At least ninety (90) days prior to publication or other
                  public disclosure of any information or data, ARC shall
                  submit to Osteotech for review a draft of the publication
                  or, if oral disclosure, a written copy of the remarks.
                  Osteotech shall then have 60 days to notify ARC of (i)
                  any reasonable changes to the publication or disclosure
                  it deems appropriate, which changes ARC will make so long
                  as they do not change materially the meaning of the
                  information or data being disclosed or published; (ii)
                  any error in the information or data being disclosed,
                  which ARC shall correct upon verification of the error;
                  or (iii) the necessity to delay publication or disclosure
                  to enable the filing of any patent application or
                  regulatory filing if applicable, in which event ARC will
                  delay such publication or disclosure as reasonably
                  requested by Osteotech.

         (c)      If there has been no mutual agreement to publish or
                  disclose within ninety (90) days after Osteotech has
                  received the notice and draft of the publication or oral
                  disclosure from ARC, ARC shall again notify, in writing,
                  Osteotech of its intention to publish or disclose and may
                  proceed to do so fifteen (15) days after Osteotech's
                  receipt of such second notice, subject to the provisions
                  of subsection (a).


                                      E-19

         (d)      Authorship of any publication shall be determined in
                  accordance with normal scientific practice.

         (e)      The provisions of this Section 2.6 shall survive
                  termination of this Agreement.

3.       FINANCIAL TERMS
3.1
         (a)      ARC will pay Osteotech Processing fees as set forth in
                  Exhibits 3.1 and 3.2.  Subject to the terms set forth in
                  Exhibits 3.1 and 3.2, such fees may be adjusted from time
                  to time, but no more frequently than annually, as set
                  forth in Exhibits 3.1 and 3.2.  Osteotech shall provide
                  ARC with suggested list prices for Osteotech's
                  proprietary products.  The initial suggested list prices
                  are set forth in Exhibit 3.2.

     (b)          In the event ARC has requested Osteotech to ship finished
                  units of Tissue to end user customers of ARC in
                  accordance with Section 2.6(a) or to perform additional
                  services in accordance with Section 2.6 (c), ARC will pay
                  Osteotech fees for such services which are to be
                  negotiated prior to institution of such services and
                  which are separate and apart from any fees established in
                  Exhibits 3.1 and 3.2 for Processing services.  In the
                  event fees become payable to Osteotech for its
                  performance of  marketing and education services in
                  accordance with Section 2.6(b), ARC will pay Osteotech
                  fees for such services which are agreed to by Osteotech
                  and ARC and which are separate and apart from any fees
                  established in Exhibits 3.1 and 3.2 for Processing
                  services.  Fees for services performed by Osteotech
                  pursuant to Section 2.6 may be adjusted from time to time
                  to adjust for changes in Osteotech's costs associated
                  with providing such services, or to make adjustment for

                                      E-20

<PAGE>



                  the addition, deletion or change in services being
                  provided.

         (c)      Unless otherwise agreed to in writing by Osteotech, in
                  the event ARC does not  deliver all Tissue recovered from
                  a donor to Osteotech, then ARC shall be invoiced by
                  Osteotech for each such donor or part thereof not
                  delivered at the average charge per donor invoiced by
                  Osteotech to ARC during the immediately preceding
                  calendar quarter.  Tissue utilized in ARC research and
                  development activities, if any, shall be excluded from
                  this requirement.

3.2      Invoicing and Payment
         (a)      Osteotech shall submit invoices in U.S. dollars to ARC
                  for all Processing services rendered in accordance with
                  the then existing fee schedule.  The invoice date shall
                  be the date that Osteotech's Quality Assurance Department
                  releases the finished units of Tissue for shipment to ARC
                  or the date that other services being performed for ARC
                  (such as serology testing, shipment of Grafton or
                  shipment of other products to end users on behalf of ARC,
                  etc.), if any, are completed.  ARC shall be separately
                  invoiced for services performed in accordance with
                  Section 2.6.

         (b)      ARC will pay all invoices within forty-five (45) days of
                  the invoice date.  All such payments shall be in U.S.
                  dollars.

         (c)      Any balance of any  invoice  which is not paid within the time
                  specified  above,  at the option of  Osteotech,  shall  accrue
                  interest at the rate of one percent (1%) per month.

4.       CONFIDENTIALITY
         (a)      For purposes of this Agreement, "Confidential
                  Information" means all general and specific knowledge,
                  experience and information that is confidential and of
                  value to ARC or to Osteotech, including without
                  limitation, formulations, designs, products, processes,
                  supplies, methods of manufacture or processing, SOPs,
                  cost data, master files, the nature of research and/or
                  development projects, as well as data relating to them,
                  marketing or business plans, donor data and financial
                  data.  It shall also mean any information disclosed to
                  either party by any third party which either ARC or
                  Osteotech is obligated to treat as confidential or
                  proprietary.

         (b)      Both parties agree that neither party will, at any time,
                  without the express agreement of the other party, or
                  except as expressly permitted by this Agreement, disclose
                  to any other person or use any Confidential Information
                  of the other party, except for the purposes of performing
                  this Agreement or any successor Agreement or as may be
                  required by law,  governmental regulation or court order.
                  Information shall not be considered to be Confidential
                  Information of a party if it can be established that (i)
                  such information was in the possession of the other party
                  prior to disclosure to such other party by the party
                  claiming that it is Confidential Information (the
                  "claiming party") and such information is not otherwise
                  subject to a confidentiality agreement, (ii) such
                  information is then part of the public domain and became
                  so without the breach of this or any other
                  confidentiality agreement by such other party or any of
                  its affiliates, (iii) or such information is developed
                  independently by such other party or becomes known to or
                  acquired by such other party by means other than as a

                                      E-22

<PAGE>



                  result of a breach of a confidentiality agreement or any
                  fiduciary obligation.

         (c)      ARC and Osteotech each agree to require employees, consultants
                  or others granted access to such  Confidential  Information to
                  execute appropriate Confidentiality Agreements;  provided that
                  each   organization's   agreements   are   approved   by  such
                  organization's counsel.

         (d)      ARC and Osteotech recognize that violation in any
                  material respect of any provision of subsection (b) may
                  cause irreparable injuries to Osteotech or ARC and agree
                  that ARC or Osteotech shall be entitled to preliminary
                  and final injunctive relief against such violation.  Such
                  injunctive relief shall be in addition to, and in no way
                  in limitation of, any and all remedies or rights which
                  ARC or Osteotech shall have at law or in equity for the
                  enforcement of the provisions of this Section.  In
                  addition, ARC and Osteotech agree that the party
                  responsible for the breach of confidentiality shall be
                  responsible for all legal fees and other costs and
                  expenses incurred in the successful enforcement of the
                  non-breaching party's rights and remedies under this
                  Section.

         (e)      The provision of this Section 4 shall survive the
                  termination of this Agreement.

                  its creditors; or such other party applying for or
                  consenting to the appointment of a receiver, trustee or
                  similar officer for its assets; or the appointment of a
                  receiver, trustee or similar officer for such other
                  party's assets without the application or consent of such

                  undischarged for a period of ninety (90) days; or such
                  other party instituting (by petition, application,

                  arrangement  or similar  proceeding  relating  to it under the
                  laws  of  any   jurisdiction;   or  the   institution  of  any
                  bankruptcy,   insolvency  arrangement  or  similar  proceeding
                  relating to such other party, if such proceeding  shall remain

                  writ,  warrant of attachment  or execution or similar  process
                  shall not be released,  vacated or fully bonded  within ninety
                  (90) days after its issue or levy.

6.2      ARC may  terminate  this  Agreement  at any time upon ninety (90) days'
         prior written notice to Osteotech if ARC makes a  determination  to end
         its program of procuring and distributing Tissue;  provided that if ARC
         resumes  such  program at any time  during the initial ten year term of
         this   Agreement  it  shall  provide  prompt  written  notice  of  such
         resumption to Osteotech and this Agreement shall become effective again
         in accordance with its terms as soon as is practicable, but in no event
         later than ninety (90) days after such notice is received by Osteotech.

6.3      ARC may  terminate  this  Agreement  in  whole or in part if and to the
         extent a third party  develops a commercially  feasible  technology for
         processing  that yields a product with greater safety and efficacy than
         the  product  produced  by  exclusive  use  of  Osteotech's  Processing
         technology and methods as demonstrated  and agreed to by a panel of six
         mutually   agreed   upon   experts   using   data   collected   in  two
         well-controlled,  scientifically-accepted  in-vivo models and Osteotech
         is unable or unwilling to achieve  comparable safety and/or efficacy of
         that  technology  within a reasonable  time  period,  not to exceed six
         months, unless otherwise agreed to by the parties in

                                      E-25

<PAGE>



         writing;  provided  that if six such  experts  are not  available,  the
         parties will use their best efforts to cause such panel to have as many
         experts (up to six) as are  reasonably  available.  This  paragraph may
         apply to all or a portion of the Tissue products processed by Osteotech
         for ARC.

6.4      In the  event ARC  enters  into an  agreement  or  arrangement  whereby
         finished  units of Tissue  processed by  Osteotech  for ARC are used as
         part of such third party's  technology or product,  ARC shall  promptly
         inform  Osteotech  of its  intent  to  enter  into  such  agreement  or
         arrangement  and Osteotech  shall have the right to (i) terminate  this
         Agreement at any time upon 90 days prior written  notice to ARC without
         any further  obligation  to ARC or (ii)  renegotiate  the terms of this
         Agreement.

6.5      ARC may  terminate  this  Agreement  at any time  upon 30  days'  prior
         written  notice to  Osteotech  if  Osteotech  is unwilling or unable to
         comply with the provisions of Section 1.2.2(b).

7.       INSURANCE
         (a)      Osteotech agrees to secure and maintain in force
                  reasonable and adequate insurance coverage for
                  Osteotech's Tissue Processing activities, provided such
                  coverage is available at reasonable prices and on
                  reasonable terms, if at all.  If such coverage is not
                  available to Osteotech, Osteotech shall inform ARC of the
                  reasons why such coverage is unavailable and shall
                  operate on a self-insured basis to the extent such
                  coverage is not available until such time as such
                  coverage does become available to Osteotech.  Subject to
                  the foregoing, Osteotech will use its best efforts to
                  obtain insurance which will include:  (a) a commercial
                  general liability policy in an amount not less than

                  than  $10,000,000;  (c) an  auto  liability  policy  including
                  owned,  non-owned,  uninsured and under-insured motorists with

                  replacement  value  protecting  Tissue of ARC in  process  and
                  storage from the perils of fire, lightning, extended coverage,
                  vandalism,  flood,  earthquake,  theft,  and all other  perils
                  commonly  included  in  the  term  "All  Risk"  form,  and  in
                  addition, coverage of not less than the insurable value of the
                  property insured by such policy for consequential loss covered
                  by failure of power,  either off  premises or on, that creates
                  an  interruption  in service to  heating,  refrigeration,  air
                  conditioning  or  other  electrical   equipment  and  business
                  interruption  coverage  in  the  amount  of $8  million.  Such
                  coverage will include Force Majeure perils.

                  Osteotech shall provide ARC with a certificate of insurance or
                  other  documentation  as proof of  insurance  required  herein
                  prior to  commencement  of services  and renewal  certificates
                  within 10 days of  expiration or  non-renewal  of the policies
                  required  herein,  as  long as this  Agreement  is in  effect.
                  Osteotech  shall  use its  best  efforts  to  cause  ARC,  its
                  directors,  officers,  employees  and  agents  to be listed as
                  additional  insureds  with respect to  Osteotech's  commercial
                  general liability,  products  liability,  auto liability,  and
                  property insurance as described herein.

         (c)      Osteotech shall require each subcontractor or assignee
                  (if any are permitted by ARC) to procure and maintain
                  insurance of the types and amounts required of Osteotech.
                  In addition, once approved by ARC, the subcontractor or
                  assignees shall sign the hold harmless agreement as it
                  appears in Section 2.2(a) in favor of ARC.  If there is
                  any assignment to a majority-owned subsidiary of
                  Osteotech as provided in Section 9 of this agreement,
                  that subsidiary shall meet each requirement of this
                  Section 7.

         (d)      ARC shall secure and maintain in force reasonable and adequate
                  insurance   coverage   for  ARC's   Tissue   procurement   and
                  distribution  activities.   ARC  shall  deliver  to  Osteotech
                  certificates  of  insurance  within  fifteen  (15) days  after
                  execution of this Agreement.

         (e)      Osteotech  shall be  liable at all  times  for  damages  to or
                  destruction of Osteotech's  equipment and material,  including
                  the loss of use  thereof,  regardless  of how such  damage  or
                  destruction occurs, except to the extent otherwise provided in
                  Section  2.2(b).  Except to the extent  otherwise  provided in
                  Section 2.2(b), ARC shall be

<PAGE>



                  under no liability to reimburse Osteotech for any such loss or
                  damage thereto,  and Osteotech waives any right of subrogation
                  against ARC.

8.       FORCE MAJEURE
         Neither party shall be responsible to the other for  nonperformance  or
delayed  performance of the terms and conditions hereof due to acts of God, acts
of  government,  wars,  riots,  accidents and  transportation,  fuel or material
shortages,  or other causes  (except  strikes),  in the nature of force  majeure
which is beyond  its  control.  To the  extent  Osteotech  is unable to  perform
Processing of ARC's Tissue due to such events,  Osteotech  shall arrange to have
ARC's  Tissue  processed  under  Osteotech's  oversight  within  30  days of the
occurrence of such event.  Notwithstanding  the above,  in the event of total or
partial  destruction  of any  processing  facility of Osteotech  utilized in the
Processing of ARC Tissues,  Osteotech  shall agree to rebuild such plant or part
thereof  within a  reasonable  period  of time and  agrees  to  arrange  for the
Processing, under Osteotech oversight, of ARC Tissue during such period.

9.       ASSIGNMENT
         Except as otherwise  expressly herein provided,  this Agreement may not
be assigned in whole or in part without the prior  written  consent of the other
party,  provided that Osteotech may assign its rights under the Agreement to any
majority-owned subsidiary of Osteotech without the consent of ARC.

10.      NAME, EMBLEM, PACKAGING, TECHNOLOGY AND TRADEMARK
         (a)      Without the prior written consent of ARC, Osteotech shall
                  have  no  right  to use  the  trademark  or  emblem  of ARC in
                  connection  with its Processing  activities or to use the name
                  of  ARC  for  commercial  purposes.   However,  Osteotech  may
                  disclose  ARC's name as may be required  by law or  government
                  regulation.

         (b)      Except as required by law or government regulations, ARC shall
                  not  have  the  right  to  use  any  trademark  or  emblem  of
                  Osteotech,  including  the name  Osteotech,  without the prior
                  written consent of Osteotech.

         (c)      (i) Nothing in this  Agreement  shall be interpreted to convey
                  to ARC any trademark,  patent or proprietary  technology owned
                  by  Osteotech;   (ii)  Nothing  in  this  Agreement  shall  be
                  interpreted to convey to Osteotech any trademark,  patent,  or
                  proprietary technology owned by ARC.

         (d)      ARC recognizes that Osteotech performs processing services for
                  other clients in addition to ARC, and  therefore,  agrees that
                  unless  specifically  developed  or  customized  for ARC or as
                  otherwise  provided herein,  all packaging and technology used
                  by Osteotech to perform processing  services will also be used
                  to perform such services for Osteotech's other clients.

         (e)      ARC recognizes that Osteotech  processes  proprietary forms of
                  tissue and agrees that if it were to distribute  these tissues
                  it will do so only under the trademark,  packaging, labels and
                  emblems developed and provided by Osteotech.

          (f)     ARC  shall  not  advertise  or  otherwise   promote  Osteotech
                  proprietary   products   or   processes   (including   without
                  limitation,  Grafton)  without  Osteotech's  prior  review and
                  written approval of all such programs and related material.

                  MARKETING AND EDUCATION SERVICES ARRANGEMENT


Osteotech shall provide  American Red Cross marketing and education  services as
shall be mutually agreed to between the parties from time to time. Such services
shall be aimed at expanding the demand for Osteotech  processed allograft tissue
distributed  by American  Red Cross.  However,  Osteotech  will not provide such
services in a manner that  adversely  impacts  customer  relationships  of other
Osteotech clients.

Services provided by Osteotech may include, but are not limited to:

o        Providing  support by Osteotech's  direct field  organization to market
         and provide medical education for Grafton,  other proprietary  products
         and base tissue products.
o        Provide  support by  Osteotech's  agency  network to market and provide
         medical education for Grafton and other proprietary products.
o        Provide training support for American Red Cross field sales
         and area personnel.
o        Support in development of sales and marketing materials.
o        Telemarketing support.
o        Participate in sales and marketing planning meetings.

All mutually agreed to marketing and education  services of the nature described
above shall be provided to American Red Cross by Osteotech without charge.  Such
services shall be determined, in part, based upon annual business plans provided
to  Osteotech  at least  three  (3)  months  prior to the  commencement  of each
American  Red Cross  fiscal  year.  To measure the  effectiveness  of  Osteotech
provided marketing and education  services,  American Red Cross shall provide to
Osteotech  such  accurate  data as  Osteotech  may require in such  intervals as
Osteotech may require.

consisting of approximately 7,040 square feet situated at 1151 Shrewsbury Avenue
presently  occupied by Asbury Park Press (such premises being  cross-hatched  on

given to  Landlord  within  said period  (hereinafter  referred to as  "Tenant's
Notice"),  to lease the  Additional  Premises  upon and  subject  to the  terms,
provisions,  covenants and conditions  hereinafter  set forth. In the event that
Tenant shall fail to send  Tenant's  Notice within said thirty (30) days period,
Landlord  shall  thereafter be free to enter into a lease with such other person
or entity for the leasing of the  Additional  Premises  and Tenant shall have no
further rights under this provision.

                  (A)      From the Additional Premises Commencement Date
                           through February 28, 2002: TWO HUNDRED NINETY SEVEN
                           THOUSAND AND 00/100 ($297,000.00) DOLLARS per annum

                           ($27,000.00) per month.

         iii.  The  Additional  Premises  shall be included in  determining  and
calculating  Tenant's  obligations  for  the  payment  and/or  reimbursement  to
Landlord or otherwise  of all  additional  rent,  charges or other monies due or

                                      E-42

<PAGE>



         v. The  extension  option  provided  for in  Paragraph 4 below shall be
deemed to apply to the entire  Demised  Premises,  inclusive  of the  Additional
Premises, and any exercise of such extension option shall be deemed to mean that
Tenant  shall  have  elected  to  continue  the Lease as to the  entire  Demised
Premises, inclusive of the Additional Premises.
         vi.      Exhibit A presently annexed to the Lease shall be deleted
therefrom, and the Exhibit A annexed hereto shall be substituted in
lieu thereof.

         3(c). The parties shall execute,  acknowledge and deliver to each other
all such  documents as may be necessary to modify the Lease as  contemplated  by
the  provisions  of this  Paragraph  within ten (10) days  following  request by
either party.
         3(d).  Landlord  acknowledges that the exercise by Tenant of its rights
under this  Paragraph  shall not  increase  the amount of the  security  deposit
required under the Lease.  Landlord further  acknowledges that the amount of the
security  deposit  presently  held by the  Landlord  is in  accordance  with the
requirements of the Lease, as modified to date.
         4.(a)             Tenant shall have the option, provided it is not in
default hereunder, to extend the term of this Lease for ONE (1)
successive additional term of FIVE (5) years, upon the same terms
and conditions as provided herein, except that the annual minimum
rental during said extension period shall be as provided below, and
except that Tenant shall have no further extension options.  Tenant

                                      E-43

<PAGE>



shall give written notice to Landlord ("Tenant's  Extension Notice") on or prior
to that date which is twelve (12)  months  prior to the  Expiration  Date of its
election  to extend the term hereof or such option  shall be deemed  waived.  If
Tenant shall exercise such extension option, the parties will, at the request of
either,  execute an agreement in form for recording,  evidencing such extension.
If Tenant shall exercise such extension option,  all references in this Lease to
the term hereof  shall be deemed to mean the term as so  extended,  except where
expressly otherwise provided.
           (b) If Tenant  shall duly and timely elect to extend the term of this
Lease,  the annual  minimum  rental  payable by Tenant for the extension term of
this Lease shall be that amount  which is the then fair market  rental value for
the Demised  Premises  which would be payable over the entire  extension term of
this  Lease  (hereinafter  referred  to as  the  "fair  rental  value").  Within
forty-five  (45) days following  receipt of Tenant's  Extension  Notice that has
been duly and timely given in accordance  with the terms hereof,  Landlord shall
serve upon Tenant  Landlord's  determination  of the annual minimum rental which
would be payable over the entire  extension term  ("Landlord's  Determination").
Tenant shall have the right, within thirty (30) days after receipt of Landlord's
Determination,  time of the  essence,  to dispute  Landlord's  Determination  by
giving  written  notice to Landlord  specifying  the basis of  Tenant's  dispute
("Tenant's Dispute Notice"). In the event Tenant shall not give Tenant's Dispute
Notice  within the time period  provided,  Tenant shall be deemed to have waived
its right to

                                      E-44

<PAGE>



dispute  Landlord's  Determination  and the annual minimum rental payable during
said  extension term shall be as set forth in Landlord's  Determination.  In the
event of such  dispute,  Landlord and Tenant agree to cooperate  with each other
and may use all  information  and means  reasonably  available in order to agree
upon the said fair rental value. In the event that for any reason whatsoever the
annual  minimum  rental  payable  during the extension  term shall not have been
determined  prior to the  commencement  of said  extension  term,  Tenant  shall
thereafter   pay  to  Landlord   (as  annual   minimum   rental  prior  to  such
determination)  the minimum  extension rental (as hereinafter  defined) in equal
monthly  installments,  with a  proper  apportionment  to be  made  after  final
determination  of the fair rental  value to be paid during the  extension  term.
Notwithstanding  anything  contained in this Paragraph 4 to the contrary,  in no
event shall the annual  minimum  rental  payable by Tenant  during the extension
term be less than the annual  minimum  rental  payable by Tenant during the last
year prior to the  Expiration  Date  (hereinafter  referred  to as the  "minimum
extension rental").
         (c) At any  time  following  Landlord's  receipt  of  Tenant's  Dispute
Notice,   either  party  may,  without   prejudice  to  any  rights  or  ongoing
negotiations  between  the  parties,  request by notice to the other  party (the
"Arbitration  Notice")  informal  arbitration to determine the fair rental value
for said  extension  term.  Said  Arbitration  Notice  shall  state the name and
address of the arbitrator picked by the party serving same, it being understood

                                      E-45

<PAGE>



and agreed that any arbitrator picked pursuant to this Paragraph shall be a fair
and  impartial  MAI member real estate  appraiser  having not less than ten (10)
years  experience  with similar  office/distribution  buildings  within Monmouth
County,  New Jersey  similar in nature to the  Buildings.  Upon  receipt of said
Arbitration  Notice,  the party receiving same shall have ten (10) days in which
to  appoint a second  arbitrator  and to give  notice to the other  party of the
same, said notice to set forth the name and address of the second arbitrator. In
the event  said other  party  fails to  appoint a second  arbitrator  within the
specified time period, said other party shall be deemed to have waived its right
to appoint a second arbitrator and the first arbitrator shall act as hereinafter
set forth  (and in such  event all  references  hereafter  to  "arbitrators"  or
"second  arbitrator" shall be deemed to mean the first arbitrator acting alone).
Thereafter,  the arbitrators shall meet together and determine,  within ten (10)
days after the second  arbitrator is  appointed,  the fair rental value for said
extension term. If said arbitrators are unable to agree within said ten (10) day
period on the fair rental value,  then said arbitrators  shall,  within ten (10)
days thereafter,  mutually agree upon a third  arbitrator.  Within ten (10) days
after appointment of the third  arbitrator,  the arbitrators shall meet together
and agree upon the fair rental value for said extension term. If the arbitrators
appointed  by the parties are unable to agree on a third  arbitrator,  the third
arbitrator  shall be appointed by  application to the Superior  Court,  Monmouth
County, New Jersey. In the event

                                      E-46

<PAGE>



of the failure,  refusal or inability of any  arbitrator  to act, an  arbitrator
shall be appointed  in his stead,  which  appointment  shall be made in the same
manner as  hereinbefore  provided  for the  appointment  of such  arbitrator  so
failing,  refusing or unable to act. The decision of the  arbitrators  appointed
and acting  hereunder  shall in all cases be final,  binding and conclusive upon
the parties. Each party shall pay the expenses of the arbitrator appointed by it
and the parties shall share equally the expenses of the third arbitrator.
         5.  Except  as  expressly  modified  herein,  all  of  the  provisions,
covenants,  conditions  and  agreements set forth in the Lease shall continue in
full force and effect.

     IN WITNESS  WHEREOF,  the parties  have caused this Fifth  Modification  of
Lease to be executed as of the day and year first above written.

                              EMPLOYMENT AGREEMENT

                  THIS  AGREEMENT  entered  into the 5th day of  December,  1996

                                   WITNESSETH:

                  WHEREAS, the Corporation desires to continue to employ

                  WHEREAS,  the Employee  desires to accept such employment upon

                  3.       Duties.  The Employee shall perform such duties and

of Directors of the Corporation.  In furtherance of the foregoing,  the Employee
hereby agrees to perform well and faithfully such duties and responsibilities.
                  4.       Time to be Devoted to Employment.

                  5.       Compensation; Reimbursement.
                           5.1a.            During the Term of Employment, the

<PAGE>



as determined by the Board of Directors of the  Corporation  based on Employee's
performance.  There will be no  guaranteed  or minimum  bonus or a stock  option

                           c.       During the Term of Employment, the Employee

                           d.       The Corporation shall reimburse Employee, in
accordance  with its  practice  from  time to time for  other  employees  of the
Corporation, for all reasonable and necessary travel expenses, disbursements and

1996 an option to purchase one hundred thousand (100,000) shares of common stock
at ten dollars  ($10.00) per share.  The option shall be exercisable over a four

<PAGE>



thereafter  on each  anniversary  of the Vesting  Date,  so long as the Employee
remains  in the  employ  of the  Corporation  on that  date.  The  option  shall
terminate ninety (90) days after  termination of the Employee's  employment with
the  Corporation  and shall be  granted  in  accordance  with the  Corporation's
Incentive Stock Option Plan as amended from time to time.
                  6.       Involuntary Termination.  If the Employee dies

during the Term of Employment for "cause" (such  termination  being  hereinafter
call  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

adversely  affects the business or affairs of the  Corporation or any subsidiary
or affiliate thereof, (ii) the Employee fails in any material respect to observe
and perform his  obligations and duties  hereunder,  (iii) the commission by the
