              Notes To Condensed Consolidated Financial Statements
                                   (unaudited)


1.       Basis of Presentation
         The accompanying  unaudited condensed consolidated financial statements
         reflect all adjustments  (consisting only of normal recurring accruals)
         considered  necessary by  management  to present  fairly the  Company's
         consolidated  financial  position as of September 30, 1997 and December
         31,  1996,  and  the   consolidated   results  of  operations  for  the
         three-month  and nine-month  periods ended September 30, 1997 and 1996,
         and the consolidated cash flows for the nine-month  periods then ended.
         The results of operations  for the respective  interim  periods are not
         necessarily indicative of the results to be expected for the full year.
         The  condensed  consolidated  financial  statements  should  be read in
         conjunction  with the audited  financial  statements for the year ended
         December 31, 1996 which were included as part of the  Company's  Report
         on Form 10-K.

2.       Earnings Per Share
         In February  1997,  the  Financial  Accounting  Standards  Board issued
         Statement of Financial  Accounting  Standards  No. 128,  "Earnings  Per
         Share" ("SFAS 128").  SFAS 128 establishes  standards for computing and
         presenting  earnings per share ("EPS") and  supersedes  APB Opinion No.
         15,  "Earnings  Per  Share"  ("Opinion  15").  SFAS  128  replaces  the
         presentation  of  primary  EPS with a  presentation  of basic EPS which
         excludes  dilution  and is  computed by dividing  income  available  to
         common  stockholders  by the  weighted-average  number of common shares
         outstanding  during the  period.  This  statement  also  requires  dual
         presentation  of basic EPS and  diluted  EPS on the face of the  income
         statement for all periods presented.  Diluted EPS is computed similarly
         to fully  diluted EPS pursuant to Opinion 15, with some  modifications.
         SFAS 128 is  effective  for  financial  statements  issued for  periods
         ending after  December  15,  1997,  including  interim  periods.  Early
         adoption is not permitted and the statement requires restatement of all
         prior-period EPS data presented after the effective date.

         The Company will adopt SFAS 128 effective with its financial statements
         for the year ending  December 31, 1997. If SFAS 128 had been adopted at
         September 30, 1997, there would have been no material change in the EPS
         as reflected in the accompanying  financial  statements for the periods
         ended September 30, 1997 and 1996.

3.       Financing Arrangements

         Effective  as of May 1997,  the Company  amended its loan and  security
         agreement  with  a US  bank  which  provides  for  borrowings  under  a
         revolving line of credit and an equipment line of credit. The amendment
         extends  the term of the  agreement  through  May 1998 and  reduces the
         annual rate of interest on  equipment  advances  from the bank's  prime
         rate plus a margin of .25% to the bank's prime rate.

4.       Commitments and Contingencies

         Service Agreements

         Effective  April 1,  1997,  the  Company  entered  into a new five year
         exclusive  agreement  with  one  of  its  major  allograft   processing
         customers,  the Musculoskeletal  Transplant Foundation ("MTF").  During
         the nine months ended  September  30, 1997 and 1996,  MTF accounted for
         60% and 65%, respectively, of consolidated revenues.

         License and Option Agreement

         In June 1997, the Company entered into an exclusive,  worldwide license
         agreement  for  its  proprietary   PolyActive(TM)  polymer  biomaterial
         technology  and  patents  with  Matrix   Medical  BV  ("Matrix"),   The
         Netherlands.  Pursuant  to the  terms  of the  agreement,  the  Company
         received an up front license payment of 500,000 Dutch Guilders("dfl" or
         approximately  $257,000)  which was  recognized as license fee revenue.
         Matrix is required to make two additional  license  payments of 250,000
         dfl  (approximately  $126,000 at the September 30, 1997 exchange  rate)
         each on the first and second  anniversary  of the effective date of the
         agreement. Additionally, Matrix has an option to acquire the technology
         for 4 million dfl  (approximately  $2 million at the September 30, 1997
         exchange  rate)  commencing  in the  third  year of the  agreement  and
         extending through the sixth year of the agreement.

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

4.       Commitments and Contingencies (continued)

         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.  See Part II, Item 1, "Legal  Proceedings".
         Management  believes  that the suits and claims are  without  merit and
         intends to defend such actions vigorously. 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  claims  made by the  Company  in
         marketing the products.  Additionally,  the Company maintains  products
         liability  insurance  coverage.  The  Company's  insurance  carrier has
         denied coverage with respect to certain of these cases and there can be
         no assurance that the remaining claims will be covered by the Company's
         insurance  policy.  Litigation  is  subject to many  uncertainties  and
         management  is unable to predict the  outcome of the pending  suits and
         claims.  It is possible that the results of operations or liquidity and
         capital  resources of the Company  could be  adversely  affected by the
         ultimate outcome of the pending  litigation or as a result of the costs
         of  contesting  such  lawsuits  if the  ultimate  liability  materially
         exceeds  the amount that the Company  recovers  from Ulrich  and/or its
         insurance  coverage.  The Company is unable to estimate  the  potential
         liability,  if any,  that may result from the pending  litigation  and,
         accordingly,  no provision for any liability  (except for accrued legal
         costs) has been made in the consolidated financial statements.

5.       Reclassifications
         Certain of the 1996 amounts  have been  reclassified  for  comparative
         purposes.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS


Information contained herein contains "forward-looking statements" (as such term
is defined in the Private Securities Litigation Reform Act of 1995) which can be
identified  by the  use  of  forward-looking  terminology  such  as  "believes",
"expects",  "may", "will", "should", or "anticipates" or the negative thereof or
other variations thereon or comparable terminology. Certain statements contained
in "Management's  Discussion and Analysis of Financial  Condition and Results of
Operations" and other sections herein, including without limitation,  statements
regarding the Company's  liquidity  and capital  resources and other  statements
contained  herein  regarding   matters  that  are  not  historical   facts,  are
forward-looking  statements.  No assurance can be given that the future  results
covered by the  forward-looking  statements  will be  achieved.  The matters set
forth in Exhibit 99.0 to the Company's Form 10-K for the year ended December 31,
1996,  constitute  cautionary  statements  identifying  important  factors  with
respect  to  such  forward-looking  statements,   including  certain  risks  and
uncertainties,  that could  cause  actual  results to vary  materially  from the
future  results  indicated  in  such  forward-looking  statements.  The  Company
expressly  disclaims any  obligation or  understanding  to release  publicly any
updates  or  revision  to any  forward-looking  statements  contained  herein to
reflect any change in the  Company's  expectations  with  regard  thereto or any
change in events, conditions or circumstances on which any statement is based.


FOR THE THREE-MONTH AND NINE-MONTH PERIODS ENDED SEPTEMBER 30, 1997 AND 1996

Results of Operations

Net Income

Net income in the third  quarter of 1997  increased  to  $1,608,000  or $.17 per
share  compared to $251,000 or $.03 per share in the third quarter of 1996.  Net
income  in the nine  months  of 1997 was  $3,843,000  or $.43  per  share  ($.41
assuming  full  dilution)  compared  to  $624,000  or $.08 per share in the nine
months of 1996.

Following is a discussion of factors which  affected  results of operations  for
the three-month and nine-month periods ended September 30, 1997 and 1996.


Revenues

Consolidated  revenues in the third quarter of 1997 increased 32% to $11,933,000
from $9,010,000 in the third quarter of 1996 and increased 27% to $32,720,000 in
the nine months of 1997 from $25,794,000 in the nine months of 1996.



                                       -8-

Results of Operations (continued)

Domestic  revenues  increased  35%  to  $11,274,000  in  and  increased  30%  to
$30,403,000  in the nine months of 1997 from  $23,318,000  in the nine months of
1996.  The increase in domestic  revenues  resulted  principally  from increased
demand for the Company's proprietary Grafton(R)  Demineralized Bone Matrix (DBM)
allograft  processing  services which increased 78% in the third quarter and 70%
in the nine months of 1997 as compared to the same periods in 1996.

Foreign  revenues  decreased  3% in the third  quarter of 1997 to $659,000  from
$680,000 in the third  quarter of 1996 and decreased 6% in the nine months ended
September  30, 1997 to  $2,317,000  from  $2,476,000  in the nine  months  ended
September 30, 1996. Foreign revenues in 1996 included grant revenues of $158,000
and $476,000 in the third quarter and nine months,  respectively,  which did not
continue in 1997 as a result of the  discontinuance of the Company's  PolyActive
polymer  research  and  development  program  in the  fourth  quarter  of  1996.
Additionally, foreign revenues in the third quarter and nine months of 1997 were
reduced by approximately 17% and 14%, respectively,  as a result of the strength
of the US dollar  compared  to the Dutch  guilder.  The  negative  impact of the
reduction in grant revenues and the effect of exchange rates were partly reduced
in the current nine month  period by $257,000 of license fee revenues  resulting
from the licensing of the Company's proprietary PolyActive polymer technology.

During the third  quarter and nine months of 1997,  two of the  Company's  major
customers accounted for 60% and 33% and 60% and 32%, respectively, of revenues.

Cost of Services and Products

Cost of  services as a  percentage  of service  revenues  was 34% and 35% in the
third quarter and nine months of 1997, respectively,  compared to 38% and 40% in
the same  periods last year.  The decline in costs as a  percentage  of revenues
results  primarily  from (i) a shift in revenue mix toward  services with higher
gross margins; (ii) operating  efficiencies resulting from increased volume; and
(iii) an  increase  in fees  charged  to the  Company's  customers  for  certain
allograft processing services.

Cost of  products as a  percentage  of product  revenues  was 64% and 72% in the
third quarter and nine months of 1997, respectively, compared to 129% and 93% in
the same  periods last year.  The decline in costs as a  percentage  of revenues
results  primarily from a shift in product mix toward products with higher gross
margins.

Results of Operations (continued)

Marketing, General and Administrative

Marketing,  general and administrative  expenses increased  $1,111,000 or 35% in
the third quarter and $2,600,000 or 28% in the nine months of 1997,  compared to
the same  periods  last year.  The  increases  were  primarily  attributable  to
expanded  marketing  activities  associated with the continued  expansion of the
business,  increased  agent  commissions  and  increased  administrative  costs,
principally outside professional services.

Research and Development

Research and development  expenses decreased  $238,000 and $595,000,  or 22% and
18%, in the third quarter and nine months of 1997, respectively, compared to the
same periods last year. The decreases result principally from the discontinuance
of the Company's  PolyActive  polymer  research and  development  program in the
fourth quarter of 1996.

Other Income, net

Interest  income  increased  $77,000 and $137,000 in the third  quarter and nine
months of 1997, respectively, compared to the same periods in the prior year due
to a higher level of invested funds.

Interest  expense  decreased  $22,000 and $72,000 in the third  quarter and nine
months of 1997, respectively, compared to the same period in the prior year as a
result of lower outstanding debt and obligations under capital leases.

Provision for Income Taxes

The Company's effective income tax rate declined to 41% in the third quarter and
nine months of 1997,  respectively,  from 73% in the same periods last year. The
high effective income tax rate in 1996 was principally due to foreign losses for
which no current tax benefits were available. The Company's effective income tax
rate is expected to remain near the nine-month  rate of 41% for the remainder of
1997.


Liquidity and Capital Resources

At September 30, 1997, the Company had cash and cash  equivalents and short-term
investments of $14,824,000  compared to $9,277,000 at December 31, 1996. Working
capital  increased  by  $4,459,000  from  $12,273,000  at  December  31, 1996 to
$16,732,000 at September 30, 1997.

Cash flow from operating  activities  increased to $7,531,000 in the nine months
of 1997  from  $3,368,000  in the nine  months  of 1996  principally  due to the
increase in net income and a decrease in prepaid expenses.

Liquidity and Capital Resources (continued)

Additionally,  the  increase in accounts  receivable  in 1997 was lower than the
increase  in  the  same  period  of  1996.  Capital  expenditures  increased  to
$2,443,000 in the nine months of 1997 from $1,328,000 in the same period in 1996
as the  Company  continues  to invest in  facilities  and  equipment  needed for
current  and  future  business   requirements,   principally   allograft  tissue
processing capacity.  Cash flow from investing activities increased  principally
due to cash proceeds from stock option exercises.

The Company has a loan and security  agreement with a US 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  September  30,  1997,  $848,000  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  Dutch  Guilders  ("dfl"),   or  approximately
$2,523,000 at the September  30, 1997 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 the line of  credit  and,
therefore,  the Company has agreed to temporarily limit its borrowings,  if any,
to no more than 3,000,000 dfl, or approximately  $1,514,000 at the September 30,
1997 exchange rate. Additionally,  in connection with the Leiden facility lease,
the Company is required to maintain a declining bank guarantee which reduced the
amount available for borrowings to 2,704,000 dfl, or approximately $1,365,000 at
the September 30, 1997 exchange rate. There were no borrowings under this credit
line as of September 30, 1997.

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.  From time to
time the Company may seek  additional  funds through  equity or debt  financing.
However, there can be no assurances 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.

PART II. OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS


1. Orthopaedic Bone Screw Products Liability Litigation

As of November 10, 1997,  the Company was aware of being named as a defendant in
approximately 34 cases based in products  liability in connection with allegedly
defective spinal devices as described in the Company's  Quarterly Report on Form
10-Q for the quarter ended March 31, 1997.  This  represents a decrease from the
79 cases  previously  reported in such  Quarterly  Report.  Of the 34  remaining
cases,  32 have been  consolidated  with other similar  actions for  coordinated
proceedings  in the Eastern  District of  Pennsylvania  under the caption In re:
Orthopedic  Bone Screw Products  Liability  Litigation,  MDL Dkt. 1014 (the "MDL
Litigation").
The  two  remaining   cases  are  pending  in  the  state  courts  of  Ohio  and
Pennsylvania.

On  October  14,  1997,  the  Company  was  served  with a  motion  filed by the
plaintiffs  requesting an order  dismissing  the Company as a defendant in 27 of
the 32 cases  pending in the MDL  Litigation,  with the  Company to bear its own
costs.  On October 31,  1997,  the Company  served its  response to  plaintiffs'
motion,  wherein the Company  agreed to the  dismissals but opposed the issue of
the Company  having to bear its own costs.  Additionally,  the Company  served a
cross-motion  against the plaintiffs and their attorneys for an order dismissing
any and all remaining  cases against the Company in the MDL  Litigation  and for
sanctions,  including but not limited to the Company's  attorneys fees and costs
incurred as a result of its involvement as a defendant in the MDL Litigation.


2. Patent Litigation

The Company is involved  in an  infringement  action  against  LifeNet  Research
Foundation and LifeNet Transplant  Services  ("LifeNet") in the Eastern District
Court of Virginia  alleging that LifeNet has infringed US Patent Nos.  5,333,626
and 5,513,662  owned by the Company.  LifeNet  alleges that such patents are not
infringed  and are  invalid  and  unenforceable.  The  Company  has denied  such
allegations and intends to pursue its claims against LifeNet vigorously.

product requirements. ConvaTec is presently conducting clinical trials in Europe
and the United States and expects to be marketing  their product in 1999 / 2000.
ConvaTec estimates the urinary  incontinence global market to be approximately $
5 billion and  believes  its device to be unique from  others  available  on the

(b)    Reports on Form 8-K

       On July 8, 1997,  the Company filed with the  Commission a Current Report
       on Form 8-K dated June 30, 1997 (the "Form 8-K"), to announce that it had
       entered into an exclusive,  worldwide licensing and option agreement (the
       "Agreement")  for its  proprietary  PolyActive(TM)  polymer  biomaterials
       technology  and patents with Matrix  Medical  B.V.,  The  Netherlands,  a
       developer  of hybrid  technology  for  tissue  replacement.  Terms of the
       Agreement  call for the  Registrant  to  receive  an  upfront  payment of
       500,000  Dutch  Guilders  ("dfl" or  approximately  $250,000  at  current
       exchange rates) and two additional payments of 250,000 dfl (approximately
       $125,000  at  current  exchange  rates)  each  on the  first  and  second
       anniversary  of the  effective  date of the  Agreement.  Pursuant  to the
       Agreement, Matrix Medical was granted an option (the "Option") to acquire
       the PolyActive  technology for 4 million dfl (approximately $2 million at
       current exchange rates) commencing in the third year of the Agreement and
       extending through the sixth year of the Agreement.

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

                         CHANGE IN CONTROL AGREEMENT


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

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

          NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          For purposes of this Agreement:

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

          (b) The  Executive's  "Base  Period  Compensation"  is (i) the average
     annual  "compensation" (as defined below) which was includible in his gross
     income for his base period  (i.e.,  his most recent five  taxable  years or
     such lesser  number of taxable years or portions  thereof  during which the
     Executive  performed services for the Company ending before the date of the
     Change in Control);  and (ii) if Executive's  base period  includes a short
     taxable  year or less than all of a  taxable  year,  compensation  for such
     short or incomplete  taxable year shall be annualized  for the base period.
     (In  annualizing  compensation,  the  frequency  with  which  payments  are
     expected  to be made over an annual  period  shall be taken  into  account.
     Thus,  any amount of  compensation  for such a short or incomplete  taxable
     year that  represents  a payment  that would not be made more than once per
     year shall not be annualized). For


<PAGE>


     purposes of this definition, Executive's "compensation" is the compensation
     which was payable to him by the Company or an Affiliate, determined without
     regard to the  following  Sections  of the  Code:  125  (cafeteria  plans),
     402(a)(8)   (cash  or  deferred   arrangements),   402(h)(1)(B)   (elective
     contributions  to  simplified  employee  pensions),  and,  in the  case  of
     employer  contributions  made  pursuant  to a salary  reduction  agreement,
     403(b) (tax sheltered annuities).

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

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

          (e) "Change in Control" shall mean:

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

               (ii) the acquisition by any  individual,  entity or group (within
          the meaning of Section  13(d)(3) or 14(d)(2) of the  Exchange  Act) (a
          "Person") of  beneficial  ownership  (within the meaning of Rule 13d-3
          promulgated  under  the  Exchange  Act)  of a  majority  of  the  then
          outstanding voting securities of the Company (the



                                       2
<PAGE>



          "Outstanding Company Voting Securities");  provided, however, that the
          following  acquisitions shall not constitute a Change in Control:  (A)
          any acquisition by the Company, or (B) any acquisition by any employee
          benefit plan (or related trust) sponsored or maintained by the Company
          or any  corporation  controlled  by the  Company,  or (C)  any  public
          offering,  private  placement or other  issuance by the Company of its
          voting securities; or

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

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

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

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

     2.   Employment Period.

          (a) Term of Employment. Commencing on the Commencement Date and ending
     on the  first  anniversary  of such  date (the  "Employment  Period"),  the
     Executive  hereby  agrees to remain in the employ of the  Company,  and the
     Company  hereby  agrees  to  continue  the  Executive  in  its  employ,  in
     accordance  with,  and  subject  to,  the  terms  and  provisions  of  this
     Agreement,  in the  capacity  of  President  and Chief  Executive  Officer,
     responsible  for,  among other  things,  the  supervision  of the Company's
     business,  and, subject to the general supervision of the Board, such other

          practices,  policies and programs  applicable  generally to other peer
          executives  of  the  Company,  but  in  no  event  shall  such  plans,
          practices,   policies  and  programs   provide  the   Executive   with
          opportunities  and benefits  less  favorable  than those in effect and
          applicable  to the  Executive  immediately  preceding  the  Change  in
          Control.

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

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

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

          in accordance with their terms immediately prior to the effective date
          of such Change in Control (and Executive will be provided a reasonable
          opportunity  to exercise such Options prior to such  effective  date),
          notwithstanding  anything  to the  contrary  contained  in the  option
          certificates  or any plan  covering  the  Options  (collectively,  the
          "Plan").  Upon a Change in Control all Options held by Executive shall
          be exercisable in accordance  with their terms for such  securities or
          property to which  Executive  would have been  entitled had



                                       5
<PAGE>



          Executive  exercised  such  Options  prior to such  Change in Control,
          notwithstanding  anything  to  the  contrary  contained  in  any  Plan
          covering  such Options.  Upon a Change in Control  pursuant to Section
          1(e)(iii) or 1(e)(v),  all Options held by  Executive,  whether or not
          vested,  shall  terminate as of the  effective  date of such Change in
          Control  to  the  extent  not  previously  exercised,   provided  that
          Executive  shall have been provided with a reasonable  opportunity  to
          exercise such options prior to such  effective  date,  notwithstanding
          anything to the contrary  contained in the Plan covering such Options.
          Notwithstanding  the foregoing,  the terms of the Option Agreement for
          the option to purchase  176,833  shares of Common Stock granted to the
          Executive on July 31, 1997 and not the terms of this  Agreement  shall
          govern  with  respect  to such  options  in the  event of a Change  in
          Control.

     3.   Termination of Employment.

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

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

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

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



                                       6
<PAGE>



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

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

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

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

               (iii)  relocation of  Executive's  office to a location  which is
          more than  fifteen  (15) miles from the  location  in which  Executive
          principally worked for the Company  immediately prior to the Change in
          Control;  or his being  required  by the  Company  in order to perform
          duties of substantially  equal status,  dignity and character to those
          duties he  performed  immediately  prior to the  Change in  Control to
          travel on the Company's  business to a  substantially  greater  extent
          than is consistent  with his business travel  obligations  immediately
          prior to a Change in Control;

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

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

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

          (d) Notice of  Termination.  Any  termination  by the Company for Just
     Cause or by the Executive for Good Reason shall be  communicated  by Notice
     of Termination  to the other party hereby given in accordance  with Section
     8. For  purposes  of this  Agreement,  a "Notice  of  Termination"  means a
     written notice



                                       7
<PAGE>



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

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

     4.   Obligations of Company upon Termination.

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

          (b)  Termination  by  Executive  for Good Reason;  Termination  by the
     Company at Any Time Other Than For Just Cause;  Termination  by the Company

     Cause; or, (ii) the Company shall terminate Executive's employment for Just
     Cause after the 180th day following the  Commencement  Date;  or, (iii) the
     Executive  shall  terminate his employment at any time for Good Reason;  or
     (iv) the  Executive's  employment with the Company shall terminate upon the

<PAGE>



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

               (ii) Executive shall receive, at the Company's expense,  medical,
          health and disability benefits which are substantially  similar to the
          benefits the Company is providing him immediately preceding the Change

          following the Date of Termination;

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

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

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

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



                                       9
<PAGE>



     otherwise.  Notwithstanding  anything  stated in this  Section  4(b) to the
     contrary,  Company shall not be required to provide medical,  health and/or
     disability  benefits to the extent such benefits would  duplicate  benefits
     received  by  Executive  in  connection  with his  employment  with any new
     employer.

          The determination of the amounts and benefits payable to the Executive
     pursuant  to  Sections  4(b)(i),  4(b)(iii)  and  4(b)(iv)  (the  "Combined
     Amount") shall first be made by the Company in good faith,  and the Company
     shall notify the Executive of the Combined Amount as soon as possible after
     the Date of  Termination,  but in no event later than  forty-five (45) days
     prior to the  payment  date of the sums due  under  Section  4(b)(iii)  and
     4(b)(iv).  If the Executive  disagrees with the Company's  determination of
     the  Combined  Amount,  then  within  ten (10) days  after the date of such
     notification  to the Executive,  the Executive  shall notify the Company of
     such disagreement,  the extent of such disagreement (the "Disputed Amount")
     and the amount that is undisputed (the "Undisputed Amount"). The Undisputed
     Amount shall be paid in one lump-sum payable sixty (60) days after the Date
     of   Termination,   subject  to  appropriate   withholding   and  statutory
     requirements.  If the Company disagrees with the Executive's  determination
     of the  Combined  Amount,  then within ten (10) days after the date of such
     notification  to the Company,  it shall  furnish  Executive  with a written
     appraisal of the Combined  Amounts (the "First  Appraisal")  prepared by an
     independent  certified public accountant  regularly employed by the Company
     (the "First Appraiser"). If Executive disagrees with the amounts determined
     pursuant to the First Appraisal,  then within ten (10) days after notice of
     the First Appraisal,  he shall furnish the Company with a written appraisal
     of the Combined Amount (the "Second Appraisal")  prepared by an independent
     certified public accountant (the "Second Appraiser").  Within ten (10) days
     after notice of the Second  Appraisal,  the First  Appraiser and the Second
     Appraiser  shall  meet and  shall  endeavor,  within  ten (10) days of such
     meeting,  to agree upon the Combined  Amount and notify the Company and the
     Executive thereof; provided, however, that if they are unable to agree upon
     the Combined  Amount,  then,  within (10) days of such meeting,  they shall
     engage an independent  certified public accountant (the "Third  Appraiser")
     and notify the Company and the  Executive of their  engagement of the Third
     Appraiser,  whose  determination of the Combined  Amount,  if any, shall be
     final and conclusive  and binding on the Company and the Executive.  Within
     ten (10) days after notice of such  engagement,  the Third  Appraiser shall
     determine  the Combined  Amount and notify the Company and the Executive of
     his determination  (the "Final Amount").  Except for the benefits described
     in Sections  4(b)(ii) and  4(b)(v),  the Final  Amount,  as adjusted by any
     prior  payment of the  Undisputed  Amount or any payment  made  pursuant to
     Section 4(b)(i),  shall be paid in one lump-sum payable on the later of (i)
     sixty (60) days after the Date of  Termination,  or (ii)  twenty  (20) days
     after  notification  of  the  Final  Amount,  in  either  case



                                       10
<PAGE>



     subject to appropriate  withholding and statutory  requirements;  provided,
     however,  that notwithstanding the foregoing,  the Executive shall have the
     option to decline the benefits  described in Section 4(b)(ii) no later than
     ten (10) days prior to such payment date.

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

     5.   Additional Payment.

     Upon a Change in Control,  Executive  shall be  entitled to a payment  (the
"Additional  Payment") equal to the product of (A) 228,167 multiplied by (B) the
amount by which (i)(x) the value of the  consideration  per share received or to
be received by the shareholders of the Company in connection with such Change in
Control  event or (y) in the event the Change in Control  does not result in any
payment to the  shareholders  of the Company,  the average of the last  reported
sale  price  of the  Company's  Common  Stock  for the  five  (5)  trading  days
immediately preceding the effective date of such Change in Control, exceeds (ii)
$12.75.  Such  Additional  Payment  shall be paid to  Executive  within five (5)
business days after the effectiveness of such Change in Control,  subject to all
withholdings required by law.

     6.   Nonexclusivity of Rights.

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future participation in any plan, program, policy or practice provided by the
Company and for which the Executive may qualify, nor shall anything herein limit
or otherwise  affect such rights as the Executive may have under any contract or
agreement  with the  Company.  Amounts  which are vested  benefits  or which the
Executive is otherwise entitled to receive under any plan,  policy,  practice or
program of or any contract or agreement with the Company at or subsequent to the
Date of  Termination  shall be payable  in  accordance  with such plan,  policy,

                           CHANGE IN CONTROL AGREEMENT


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

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

          NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          For purposes of this Agreement:

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

          (b) The  Executive's  "Base  Period  Compensation"  is (i) the average
     annual  "compensation" (as defined below) which was includible in his gross
     income for his base period  (i.e.,  his most recent five  taxable  years or
     such lesser  number of taxable years or portions  thereof  during which the
     Executive  performed services for the Company ending before the date of the
     Change in Control);  and (ii) if Executive's  base period  includes a short
     taxable  year or less than all of a  taxable  year,  compensation  for such
     short or incomplete  taxable year shall be annualized  for the base period.
     (In  annualizing  compensation,  the  frequency  with  which  payments  are
     expected  to be made over an annual  period  shall be taken  into  account.
     Thus,  any amount of  compensation  for such a short or incomplete  taxable
     year that  represents  a payment  that would not be made more than once per
     year shall not be annualized). For


<PAGE>



     purposes of this definition, Executive's "compensation" is the compensation
     which was payable to him by the Company or an Affiliate, determined without
     regard to the  following  Sections  of the  Code:  125  (cafeteria  plans),
     402(a)(8)   (cash  or  deferred   arrangements),   402(h)(1)(B)   (elective
     contributions  to  simplified  employee  pensions),  and,  in the  case  of
     employer  contributions  made  pursuant  to a salary  reduction  agreement,
     403(b) (tax sheltered annuities).

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

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

          (e) "Change in Control" shall mean:

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

               (ii) the acquisition by any  individual,  entity or group (within
          the meaning of Section  13(d)(3) or 14(d)(2) of the  Exchange  Act) (a
          "Person") of  beneficial  ownership  (within the meaning of Rule 13d-3
          promulgated  under  the  Exchange  Act)  of a  majority  of  the  then
          outstanding voting securities of the Company (the



                                       2
<PAGE>



          "Outstanding Company Voting Securities");  provided, however, that the
          following  acquisitions shall not constitute a Change in Control:  (A)
          any acquisition by the Company, or (B) any acquisition by any employee
          benefit plan (or related trust) sponsored or maintained by the Company
          or any  corporation  controlled  by the  Company,  or (C)  any  public
          offering,  private  placement or other  issuance by the Company of its
          voting securities; or

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

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

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

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

     2.   Employment Period.

          (a) Term of Employment. Commencing on the Commencement Date and ending
     on the  first  anniversary  of such  date (the  "Employment  Period"),  the
     Executive  hereby  agrees to remain in the employ of the  Company,  and the
     Company  hereby  agrees  to  continue  the  Executive  in  its  employ,  in
     accordance  with,  and  subject  to,  the  terms  and  provisions  of  this
     Agreement,  in the capacity of Executive Vice  President,  Chief  Operating
     Officer and Chief Financial  Officer,  responsible for, among other things,
     the supervision of certain  operations of the Company and the financial and
     accounting   functions  of  the  Company,   and,  subject  to  the  general
     supervision  of  the  Chief  Executive  Officer,   such  other  duties  and
     responsibilities  as are not  inconsistent  with the express  terms of this
     Agreement.

          business  hours to the business and affairs of the Company and, to the
          extent  necessary to discharge  the  responsibilities  assigned to the
          Executive hereunder, to use the Executive's reasonable best efforts to
          perform faithfully and efficiently such  responsibilities.  During the

          committees,  (B) deliver  lectures,  fulfill  speaking  engagements or
          teach  at   educational   institutions,   and  (C)   manage   personal

          the Executive  with benefits which are less favorable than such plans,
          practices,  policies  and  programs  in effect and  applicable  to the
          Executive immediately preceding the Change in Control.

               (iv) Expenses.  During the Employment Period, the Executive shall

          notwithstanding  anything  to the  contrary  contained  in the  option
          certificates  or any plan  covering  the  Options  (collectively,  the
          "Plan").  Upon a Change in Control all Options held by Executive shall

          1(e)(iii) or 1(e)(v),  all Options held by  Executive,  whether or not
          vested,  shall  terminate as of the  effective  date of such Change in

          exercise such options prior to such  effective  date,  notwithstanding
          anything to the contrary  contained in the Plan covering such Options.
          Notwithstanding  the foregoing,  the terms of the Option Agreement for
          the option to purchase  87,325  shares of Common Stock  granted to the
          Executive on July 31, 1997 and not the terms of this  Agreement  shall
          govern  with  respect  to such  options  in the  event of a Change  in
          Control.

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

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

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

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

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

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

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

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

               (iii)  relocation of  Executive's  office to a location  which is
          more than  fifteen  (15) miles from the  location  in which  Executive
          principally worked for the Company  immediately prior to the Change in
          Control;  or his being  required  by the  Company  in order to perform
          duties of substantially  equal status,  dignity and character to those
          duties he  performed  immediately  prior to the  Change in  Control to
          travel on the Company's  business to a  substantially  greater  extent
          than is consistent  with his business travel  obligations  immediately
          prior to a Change in Control;

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

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

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

          (d) Notice of  Termination.  Any  termination  by the Company for Just
     Cause or by the Executive for Good Reason shall be  communicated  by Notice
     of Termination  to the other party hereby given in accordance  with Section
     8. For  purposes  of this  Agreement,  a "Notice  of  Termination"  means a
     written notice



                                       7
<PAGE>



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

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

     4.   Obligations of Company upon Termination.

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

          (b)  Termination  by  Executive  for Good Reason;  Termination  by the
     Company at Any Time Other Than For Just Cause;  Termination  by the Company
     For Just  Cause  After the  180th  Day  Following  the  Commencement  Date;

     shall terminate the Executive's  employment at any time other than for Just
     Cause; or, (ii) the Company shall terminate Executive's employment for Just
     Cause after the 180th day following the  Commencement  Date;  or, (iii) the
     Executive  shall  terminate his employment at any time for Good Reason;  or
     (iv) the  Executive's  employment with the Company shall terminate upon the

<PAGE>



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

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

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

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

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

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



                                       9
<PAGE>



     otherwise.  Notwithstanding  anything  stated in this  Section  4(b) to the
     contrary,  Company shall not be required to provide medical,  health and/or
     disability  benefits to the extent such benefits would  duplicate  benefits
     received  by  Executive  in  connection  with his  employment  with any new
     employer.

          The determination of the amounts and benefits payable to the Executive
     pursuant  to  Sections  4(b)(i),  4(b)(iii)  and  4(b)(iv)  (the  "Combined
     Amount") shall first be made by the Company in good faith,  and the Company
     shall notify the Executive of the Combined Amount as soon as possible after
     the Date of  Termination,  but in no event later than  forty-five (45) days
     prior to the  payment  date of the sums due  under  Section  4(b)(iii)  and
     4(b)(iv).  If the Executive  disagrees with the Company's  determination of
     the  Combined  Amount,  then  within  ten (10) days  after the date of such
     notification  to the Executive,  the Executive  shall notify the Company of
     such disagreement,  the extent of such disagreement (the "Disputed Amount")
     and the amount that is undisputed (the "Undisputed Amount"). The Undisputed
     Amount shall be paid in one lump-sum payable sixty (60) days after the Date
     of   Termination,   subject  to  appropriate   withholding   and  statutory
     requirements.  If the Company disagrees with the Executive's  determination
     of the  Combined  Amount,  then within ten (10) days after the date of such
     notification  to the Company,  it shall  furnish  Executive  with a written
     appraisal of the Combined  Amounts (the "First  Appraisal")  prepared by an
     independent  certified public accountant  regularly employed by the Company
     (the "First Appraiser"). If Executive disagrees with the amounts determined
     pursuant to the First Appraisal,  then within ten (10) days after notice of
     the First Appraisal,  he shall furnish the Company with a written appraisal
     of the Combined Amount (the "Second Appraisal")  prepared by an independent
     certified public accountant (the "Second Appraiser").  Within ten (10) days
     after notice of the Second  Appraisal,  the First  Appraiser and the Second
     Appraiser  shall  meet and  shall  endeavor,  within  ten (10) days of such
     meeting,  to agree upon the Combined  Amount and notify the Company and the
     Executive thereof; provided, however, that if they are unable to agree upon
     the Combined  Amount,  then,  within (10) days of such meeting,  they shall
     engage an independent  certified public accountant (the "Third  Appraiser")
     and notify the Company and the  Executive of their  engagement of the Third
     Appraiser,  whose  determination of the Combined  Amount,  if any, shall be
     final and conclusive  and binding on the Company and the Executive.  Within
     ten (10) days after notice of such  engagement,  the Third  Appraiser shall
     determine  the Combined  Amount and notify the Company and the Executive of
     his determination  (the "Final Amount").  Except for the benefits described
     in Sections  4(b)(ii) and  4(b)(v),  the Final  Amount,  as adjusted by any
     prior  payment of the  Undisputed  Amount or any payment  made  pursuant to
     Section 4(b)(i),  shall be paid in one lump-sum payable on the later of (i)
     sixty (60) days after the Date of  Termination,  or (ii)  twenty  (20) days
     after notification of the Final Amount, in either case



                                       10
<PAGE>



     subject to appropriate  withholding and statutory  requirements;  provided,
     however,  that notwithstanding the foregoing,  the Executive shall have the
     option to decline the benefits  described in Section 4(b)(ii) no later than
     ten (10) days prior to such payment date.

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

     5.   Additional Payment

     Upon a Change in Control,  Executive  shall be  entitled to a payment  (the
"Additional  Payment") equal to the product of (A) 112,675 multiplied by (B) the
amount by which (i)(x) the value of the  consideration  per share received or to
be received by the shareholders of the Company in connection with such Change in
Control  event or (y) in the event the Change in Control  does not result in any
payment to the  shareholders  of the Company,  the average of the last  reported
sale  price  of the  Company's  Common  Stock  for the  five  (5)  trading  days
immediately preceding the effective date of such Change in Control, exceeds (ii)
$12.75.  Such  Additional  Payment  shall be paid to  Executive  within five (5)
business days after the effectiveness of such Change in Control,  subject to all
withholdings required by law.

     6.   Nonexclusivity of Rights.

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future participation in any plan, program, policy or practice provided by the
Company and for which the Executive may qualify, nor shall anything herein limit
or otherwise  affect such rights as the Executive may have under any contract or
agreement  with the  Company.  Amounts  which are vested  benefits  or which the
Executive is otherwise entitled to receive under any plan,  policy,  practice or
program of or any contract or agreement with the Company at or subsequent to the
Date of  Termination  shall be payable  in  accordance  with such plan,  policy,
practice or program or contract or agreement,  except as explicitly  modified by
this Agreement.

                         CHANGE IN CONTROL AGREEMENT


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

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

          NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          For purposes of this Agreement:

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

          (b) The  Executive's  "Base  Period  Compensation"  is (i) the average
     annual  "compensation" (as defined below) which was includible in his gross
     income for his base period  (i.e.,  his most recent five  taxable  years or
     such lesser  number of taxable years or portions  thereof  during which the
     Executive  performed services for the Company ending before the date of the
     Change in Control);  and (ii) if Executive's  base period  includes a short
     taxable  year or less than all of a  taxable  year,  compensation  for such
     short or incomplete  taxable year shall be annualized  for the base period.
     (In  annualizing  compensation,  the  frequency  with  which  payments  are
     expected  to be made over an annual  period  shall be taken  into  account.
     Thus,  any amount of  compensation  for such a short or incomplete  taxable
     year that  represents  a payment  that would not be made more than once per

          Person other than the Board; or

               (ii) the acquisition by any  individual,  entity or group (within

          the merger or consolidation, was a subsidiary of the Company, shall be
          the surviving entity; or

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

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

          teach  at   educational   institutions,   and  (C)   manage   personal

          practices,  policies and programs  applicable  generally to other peer
          executives  of  the  Company,  but  in  no  event  shall  such  plans,
          practices,   policies  and  programs   provide  the   Executive   with
          opportunities  and benefits  less  favorable  than those in effect and

          Control.

               (iii) Benefit Plans.  During the Employment Period, the Executive
          and/or the Executive's  family,  as the case may be, shall be eligible
          for  participation  in and shall  receive all benefits  under  welfare
          benefit  plans,  practices,  policies  and  programs  provided  by the

          death and travel accident  insurance plans and programs) to the extent
          applicable  generally to other peer executives of the Company,  but in
          no event shall such plans,  practices,  policies and programs  provide
          the Executive  with benefits which are less favorable than such plans,
          practices,  policies  and  programs  in effect and  applicable  to the
          Executive immediately preceding the Change in Control.

               (iv) Expenses.  During the Employment Period, the Executive shall
          be  entitled  to  receive  prompt  reimbursement  for  all  reasonable
          employment  related  expenses  incurred by the Executive in accordance

          notwithstanding  anything  to the  contrary  contained  in the  option
          certificates  or any plan  covering  the  Options  (collectively,  the
          "Plan").  Upon a Change in Control all Options held by Executive shall
          be exercisable in accordance  with their terms for such  securities or
          property to which  Executive  would have been  entitled had

          notwithstanding  anything  to  the  contrary  contained  in  any  Plan
          covering  such Options.  Upon a Change in Control  pursuant to Section
          1(e)(iii) or 1(e)(v),  all Options held by  Executive,  whether or not
          vested,  shall  terminate as of the  effective  date of such Change in
          Control  to  the  extent  not  previously  exercised,   provided  that
          Executive  shall have been provided with a reasonable  opportunity  to
          exercise such options prior to such  effective  date,  notwithstanding
          anything to the contrary  contained in the Plan covering such Options.
          Notwithstanding  the foregoing,  the terms of the Option Agreement for
          the option to purchase  43,662  shares of Common Stock  granted to the
          Executive on July 31, 1997 and not the terms of this  Agreement  shall
          govern  with  respect  to such  options  in the  event of a Change  in
          Control.

     automatically  upon the Executive's death during the Employment  Period. If
     the Company  determines in good faith that the  Disability of the Executive

     Disability set forth below), it may give to the Executive written notice in
     accordance  with Section 3(d) of its intention to terminate the Executive's
     employment.  In such event,  the  Executive's  employment  with the Company
     shall  terminate  effective on the 30th day after receipt of such notice by
     the Executive (the "Disability Effective Date"),  provided that, within the
     thirty (30) days after such receipt,  the Executive shall not have returned
     to full-time  performance of the Executive's  duties.  For purposes of this
     Agreement,  "Disability"  shall mean a physical or mental  condition  which

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

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

          connection  with  the  performance  of his  duties  on  behalf  of the
          Company.

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

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

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

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

               (iii)  relocation of  Executive's  office to a location  which is
          more than  fifteen  (15) miles from the  location  in which  Executive
          principally worked for the Company  immediately prior to the Change in
          Control;  or his being  required  by the  Company  in order to perform
          duties of substantially  equal status,  dignity and character to those
          duties he  performed  immediately  prior to the  Change in  Control to
          travel on the Company's  business to a  substantially  greater  extent
          than is consistent  with his business travel  obligations  immediately
          prior to a Change in Control;

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

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

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

          (d) Notice of  Termination.  Any  termination  by the Company for Just
     Cause or by the Executive for Good Reason shall be  communicated  by Notice
     of Termination  to the other party hereby given in accordance  with Section
     8. For  purposes  of this  Agreement,  a "Notice  of  Termination"  means a
     written  notice



                                       7
<PAGE>



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

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

     4.   Obligations of Company upon Termination.

     to  the  180th  day  following  the  Commencement   Date,  the  Executive's

     following  the  Commencement  Date,  the  Executive's  employment  shall be

          compounded semiannually.

               (iv) Except in the case of a termination  by the Company for Just
          Cause or a voluntary  termination by the Executive in accordance  with
          Section  3(c)(v),  Executive  shall  receive  the  balance of all pay,

     required to mitigate the amount of any payment provided for in this Section
     4(b) by seeking other  employment or



                                       9

     otherwise.  Notwithstanding  anything  stated in this  Section  4(b) to the
     contrary,  Company shall not be required to provide medical,  health and/or
     disability  benefits to the extent such benefits would  duplicate  benefits
     received  by  Executive  in  connection  with his  employment  with any new
     employer.

          The determination of the amounts and benefits payable to the Executive
     pursuant  to  Sections  4(b)(i),  4(b)(iii)  and  4(b)(iv)  (the  "Combined
     Amount") shall first be made by the Company in good faith,  and the Company
     shall notify the Executive of the Combined Amount as soon as possible after
     the Date of  Termination,  but in no event later than  forty-five (45) days
     prior to the  payment  date of the sums due  under  Section  4(b)(iii)  and
     4(b)(iv).  If the Executive  disagrees with the Company's  determination of
     the  Combined  Amount,  then  within  ten (10) days  after the date of such
     notification  to the Executive,  the Executive  shall notify the Company of
     such disagreement,  the extent of such disagreement (the "Disputed Amount")
     and the amount that is undisputed (the "Undisputed Amount"). The Undisputed
     Amount shall be paid in one lump-sum payable sixty (60) days after the Date
     of   Termination,   subject  to  appropriate   withholding   and  statutory
     requirements.  If the Company disagrees with the Executive's  determination
     of the  Combined  Amount,  then within ten (10) days after the date of such
     notification  to the Company,  it shall  furnish  Executive  with a written
     appraisal of the Combined  Amounts (the "First  Appraisal")  prepared by an
     independent  certified public accountant  regularly employed by the Company
     (the "First Appraiser"). If Executive disagrees with the amounts determined
     pursuant to the First Appraisal,  then within ten (10) days after notice of
     the First Appraisal,  he shall furnish the Company with a written appraisal
     of the Combined Amount (the "Second Appraisal")  prepared by an independent
     certified public accountant (the "Second Appraiser").  Within ten (10) days
     after notice of the Second  Appraisal,  the First  Appraiser and the Second
     Appraiser  shall  meet and  shall  endeavor,  within  ten (10) days of such
     meeting,  to agree upon the Combined  Amount and notify the Company and the
     Executive thereof; provided, however, that if they are unable to agree upon
     the Combined  Amount,  then,  within (10) days of such  meeting,they  shall
     engage an independent  certified public accountant (the "Third  Appraiser")
     and notify the Company and the  Executive of their  engagement of the Third
     Appraiser,  whose  determination of the Combined  Amount,  if any, shall be
     final and conclusive  and binding on the Company and the Executive.  Within
     ten (10) days after notice of such  engagement,  the Third  Appraiser shall
     determine  the Combined  Amount and notify the Company and the Executive of
     his determination  (the "Final Amount").  Except for the benefits described
     in Sections  4(b)(ii) and  4(b)(v),  the Final  Amount,  as adjusted by any
     prior  payment of the  Undisputed  Amount or any payment  made  pursuant to
     Section 4(b)(i),  shall be paid in one lump-sum payable on the later of (i)
     sixty (60) days after the Date of  Termination,  or (ii)  twenty  (20) days
     after  notification  of  the  Final  Amount,  in  either  case



                                       10
<PAGE>



     subject to appropriate  withholding and statutory  requirements;  provided,
     however,  that notwithstanding the foregoing,  the Executive shall have the
     option to decline the benefits  described in Section 4(b)(ii) no later than
     ten (10) days prior to such payment date.

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

     5.   Additional Payment.

     Upon a Change in Control,  Executive  shall be  entitled to a payment  (the
"Additional  Payment") equal to the product of (A) 56,338  multiplied by (B) the
amount by which (i)(x) the value of the  consideration  per share received or to
be received by the shareholders of the Company in connection with such Change in
Control  event or (y) in the event the Change in Control  does not result in any
payment to the  shareholders  of the Company,  the average of the last  reported
sale  price  of the  Company's  Common  Stock  for the  five  (5)  trading  days
immediately preceding the effective date of such Change in Control, exceeds (ii)
$12.75.  Such  Additional  Payment  shall be paid to  Executive  within five (5)
business days after the effectiveness of such Change in Control,  subject to all
withholdings required by law.

     6.   Nonexclusivity of Rights.

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future participation in any plan, program, policy or practice provided by the
Company and for which the Executive may qualify, nor shall anything herein limit
or otherwise  affect such rights as the Executive may have under any contract or
agreement  with the  Company.  Amounts  which are vested  benefits  or which the
Executive is otherwise entitled to receive under any plan,  policy,  practice or
program of or any contract or agreement with the Company at or subsequent to the
Date of  Termination  shall be payable  in  accordance  with such plan,  policy,
practice or program or contract or agreement,  except as explicitly  modified by
this Agreement.

                         CHANGE IN CONTROL AGREEMENT


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

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

          NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          For purposes of this Agreement:

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

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



<PAGE>



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

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

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

          (e) "Change in Control" shall mean:

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

               (ii) the acquisition by any  individual,  entity or group (within
          the meaning of Section  13(d)(3) or 14(d)(2) of the  Exchange  Act) (a
          "Person") of



                                       2
<PAGE>



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

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

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

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

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

     2.   Employment Period.

          (a) Term of Employment. Commencing on the Commencement Date and ending
     on the  first  anniversary  of such  date (the  "Employment  Period"),  the

     Company  hereby  agrees  to  continue  the  Executive  in  its  employ,  in
     accordance  with,  and  subject  to,  the  terms  and  provisions  of  this

          extent  necessary to discharge  the  responsibilities  assigned to the
          Executive hereunder, to use the Executive's reasonable best efforts to
          perform faithfully and efficiently such  responsibilities.  During the
          Employment  Period it shall not be a violation of this  Agreement  for

          teach  at   educational   institutions,   and  (C)   manage   personal

          opportunities  and benefits



                                       4

          less  favorable  than those in effect and  applicable to the Executive
          immediately preceding the Change in Control.

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

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

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

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

               (vii)  Options.  Upon a Change in Control all options to purchase
          shares  of  the  Company's   Common  Stock  held  by  Executive   (the
          "Options"),  whether or not vested,  shall vest and become exercisable
          in accordance with their terms immediately prior to the effective date
          of such Change in Control (and Executive will be provided a reasonable
          opportunity  to exercise such Options prior to such  effective  date),
          notwithstanding  anything  to the  contrary  contained  in the  option



                                       5
<PAGE>



          certificates  or any plan  covering  the  Options  (collectively,  the
          "Plan").  Upon a Change in Control all Options held by Executive shall
          be exercisable in accordance  with their terms for such  securities or
          property to which  Executive  would have been  entitled had  Executive
          exercised   such   Options   prior   to  such   Change   in   Control,
          notwithstanding  anything  to  the  contrary  contained  in  any  Plan
          covering  such Options.  Upon a Change in Control  pursuant to Section
          1(e)(iii) or 1(e)(v),  all Options held by  Executive,  whether or not
          vested,  shall  terminate as of the  effective  date of such Change in
          Control  to  the  extent  not  previously  exercised,   provided  that
          Executive  shall have been provided with a reasonable  opportunity  to
          exercise such options prior to such  effective  date,  notwithstanding
          anything to the contrary  contained in the Plan covering such Options.
          Notwithstanding  the foregoing,  the terms of the Option Agreement for
          the option to purchase  50,212  shares of Common Stock  granted to the
          Executive on July 31, 1997 and not the terms of this  Agreement  shall
          govern  with  respect  to such  options  in the  event of a Change  in
          Control.

     3.   Termination of Employment.

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

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

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



                                       6
<PAGE>



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

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

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

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

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

               (iii)  relocation of  Executive's  office to a location  which is
          more than  fifteen  (15) miles from the  location  in which  Executive
          principally worked for the Company  immediately prior to the Change in
          Control;  or his being  required  by the  Company  in order to perform
          duties of substantially  equal status,  dignity and character to those
          duties he  performed  immediately  prior to the  Change in  Control to
          travel on the Company's  business to a  substantially  greater  extent
          than is consistent  with his business travel  obligations  immediately
          prior to a Change in Control;

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

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

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



                                       7
<PAGE>



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

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

     4.   Obligations of Company upon Termination.

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

          (b)  Termination  by  Executive  for Good Reason;  Termination  by the
     Company at Any Time Other Than For Just Cause;  Termination  by the Company
     For Just  Cause  After the  180th  Day  Following  the  Commencement  Date;
     Termination  Upon Expiration of the Employment  Period.  If (i) the Company
     shall terminate the Executive's  employment at any time other than for Just
     Cause; or, (ii) the Company shall terminate Executive's employment for Just



                                       8
<PAGE>



     Cause after the 180th day following the  Commencement  Date;  or, (iii) the
     Executive  shall  terminate his employment at any time for Good Reason;  or
     (iv) the  Executive's  employment with the Company shall terminate upon the
     expiration  of the  Employment  Period,  in  addition  to any  other  sums,
     benefits or compensation otherwise payable to him by the Company:

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

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

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

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

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

          The  foregoing  payments  and  benefits  shall be deemed  compensation
     payable  for duties to be  performed  by  Executive  pursuant to Section 2.
     Except  for the  payments  and  benefits



                                       9
<PAGE>



     described in Sections 4(b)(i),  4(b)(ii), and 4(b)(v) the sums due pursuant
     to this Section  4(b) shall be paid in one  lump-sum  payable no later than
     sixty  (60)  days  after  the Date of  Termination.  All sums of money  due
     hereunder  shall  be  subject  to  appropriate  withholding  and  statutory
     requirements. Executive shall not be required to mitigate the amount of any
     payment  provided for in this Section 4(b) by seeking  other  employment or
     otherwise.  Notwithstanding  anything  stated in this  Section  4(b) to the
     contrary,  Company shall not be required to provide medical,  health and/or
     disability  benefits to the extent such benefits would  duplicate  benefits
     received  by  Executive  in  connection  with his  employment  with any new
     employer.

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



                                       10
<PAGE>



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

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

     5.   Additional Payment

     Upon a Change in Control,  Executive  shall be  entitled to a payment  (the
"Additional  Payment") equal to the product of (A) 64,788  multiplied by (B) the
amount by which (i)(x) the value of the  consideration  per share received or to
be received by the shareholders of the Company in connection with such Change in
Control  event or (y) in the event the Change in Control  does not result in any
payment to the  shareholders  of the Company,  the average of the last  reported
sale  price  of the  Company's  Common  Stock  for the  five  (5)  trading  days
immediately preceding the effective date of such Change in Control, exceeds (ii)
$12.75.  Such  Additional  Payment  shall be paid to  Executive  within five (5)
business days after the effectiveness of such Change in Control,  subject to all
withholdings required by law.

     6.   Nonexclusivity of Rights.

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future participation in any plan, program, policy or practice provided by the
Company and for which



                                       11
<PAGE>



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

     7.   Successors; Binding Agreement.

          (a) The Company will require any successor (whether direct or indirect
     by purchase,  merger,  consolidation or otherwise,  to all or substantially
     all of the business  and/or assets of the Company) to expressly  assume and
     agree to perform  this  Agreement in the same manner and to the same extent
     that the Company would be required to perform it if no such  succession had
     taken place.

          (b) This Agreement shall inure to the benefit of and be enforceable by
     Executive's personal or legal representatives,  executors,  administrators,
     successors, heirs, distributees, devisees and legatees.

     9.  Miscellaneous.  This Agreement may not be modified or discharged unless
such  waiver,  modification  or  discharge is agreed to in writing and signed by
Executive and such officers of the Company as may be specifically  designated by
