                                 OSTEOTECH, INC.
                                 2000 STOCK PLAN
                         RESTRICTED STOCK UNIT AGREEMENT
                                (FOR CONSULTANTS)

     THIS RESTRICTED STOCK UNIT AGREEMENT (the "Agreement"), is dated as of
[____________, _____] (the "Grant Date") by and between Osteotech, Inc., a
Delaware corporation (the "Company"), and [_________________], a consultant of
the Company or a subsidiary of the Company (the "Consultant") located at
_______________________________________, pursuant to the Company's Amended and
Restated 2000 Stock Plan (the "Plan").

     For good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the Company and Consultant hereby agree as follows:

1.   Grant of Stock Units.

     Subject to the terms and conditions of this Agreement and of the Plan, the
Company hereby grants to the Consultant restricted stock units ("Stock Units")
covering [__________] shares (the "Shares") of the Company's common stock (the
"Common Stock"). Each Stock Unit represents one share of Common Stock.

2.   Vesting Schedule.

     (a) Subject to the Consultant's not experiencing a termination of service
from the Company or its subsidiaries for any reason during the following vesting
period, the interest of the Consultant in the Stock Units shall vest, and Shares
shall be issued in accordance with Section 3 below, as follows:

<TABLE>
<CAPTION>
                Percentage of Total Shares Subject to Stock Units for Which
     Date                   Stock Units are Vested and Issuable
     ----       -----------------------------------------------------------
<S>             <C>
[Vest date 1]                       [_________________]
[Vest date 2]                       [_________________]
[Vest date 3]                       [_________________]
[Vest date 4]                       [_________________]
</TABLE>

     Therefore, provided the Consultant has not ceased being a consultant of the
Company or its subsidiaries prior to the close of business on the last day
provided for in the schedule of vesting dates above, the interest of the
Consultant in the Stock Units shall become fully vested on that date, and all
Shares will have been issued in accordance with Section 3 below on or prior to
that date.


                                        1

     (b) Except as otherwise provided for in this Agreement, if the Consultant
ceases to be a consultant of the Company or its subsidiaries for any reason
including as a result of the Consultant's death or disability (within the
meaning of Section 22(e)(3) of the Code) prior to the end of the Restriction
Period (as defined below), all Stock Units granted hereunder that have not
vested by the Consultant's termination date and that are held by the Consultant
as of such date shall be forfeited by, and no further rights shall accrue to,
the Consultant.

3.   Benefit Upon Vesting.

     Upon the vesting of the Stock Units, the Consultant shall be entitled to
receive, and the Company shall issue to the Consultant, a number of Shares equal
to the number of Stock Units that have vested on the applicable vesting date.

4.   Adjustment of Shares.

     (a) The number of shares issuable upon vesting of the Stock Units shall be
adjusted proportionately in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be provided under the Stock Units
upon the occurrence of a stock split or reverse stock split or a dividend
payable to all holders of the Common Stock in shares of Common Stock. The
provisions of this Section 4(a) reflect the determination of the Compensation
Committee as authorized in Section 4(c) of the Plan.

     (b) In the event of a dissolution or liquidation of the Company all
unvested Stock Units shall terminate.

     (c) In the event that the Company is a party to a merger or consolidation,
the Stock Units shall be subject to the agreement of merger or consolidation.
Such agreement, without the Consultant's consent, may provide for:

          (i) The continuation of the Stock Units by the Company (if the Company
is the surviving corporation);

          (ii) The assumption of the Plan and the Stock Units by the surviving
corporation or its parent;

          (iii) The substitution by the surviving corporation or its parent of
stock units with substantially the same terms as the Stock Units; or

          (iv) The cancellation of the Stock Units, provided that the Company
shall have the right prior to such merger or consolidation to issue the Shares
subject to the Stock Units in whole or in part, whether or not the Consultant's
right to issuance of the Shares subject to the Stock Units has otherwise accrued
pursuant to Section 2 of this Agreement.

5.   Restrictions.

     Except as otherwise provided for in this Agreement or applicable law, the
Stock Units or rights granted hereunder may not be sold, pledged or otherwise
transferred until the Stock Units


                                        2

<PAGE>

become vested in accordance with Section 2 and the Shares are issued under
Section 3. The period of time between the Grant Date and the final date all of
the Stock Units become fully vested is referred to herein as the "Restriction
Period."

6.   No Stockholder Rights.

     Stock Units represent hypothetical shares of Common Stock. During the
Restriction Period, the Consultant shall not be entitled to any of the rights or
benefits generally accorded to stockholders with respect to the Stock Units.

7.   Taxes.

     (a) The Consultant shall be liable for any and all taxes of any nature and
whether arising under U.S., state, local or foreign laws, including withholding
taxes, interest or penalties, if any, arising out of this grant, the vesting of
Stock Units hereunder, the transfer of Shares or other property in settlement of
the Stock Units or any subsequent transfer or disposition of the Shares or such
property.

     (b) Regardless of any action the Company takes with respect to any or all
income tax, social insurance, payroll tax, payment on account or other
tax-related withholding ("Tax-Related Items"), the Consultant acknowledges and
agrees that the ultimate liability for all Tax-Related Items legally due by the
Consultant is and remains the Consultant's responsibility and that the Company
(i) makes no representations nor undertakings regarding the treatment of any
Tax-Related Items in connection with any aspect of this grant of Stock Units,
including the vesting of Stock Units, subsequent payment of Common Stock and/or
cash related to such Stock Units or the subsequent sale or other disposition of
any Common Stock acquired pursuant to such Stock Units; and (ii) does not commit
to structure the terms or any aspect of this grant of Stock Units to reduce or
eliminate the Consultant's liability for Tax-Related Items. The Consultant shall
pay the Company any amount of Tax-Related Items that the Company may be required
to withhold as a result of the Consultant's participation in the Plan or the
Consultant's receipt of Stock Units, provided that the Company can also satisfy
any withholding obligations by any means set forth in Section 8 of the Plan, and
if the Consultant does not otherwise so pay the Company, then the Company has
the right to withhold amounts from the Consultant's cash compensation to satisfy
such withholding obligation. The Company may refuse to deliver the benefit
described in Section 3 if the Consultant fails to comply with the Consultant's
obligations in connection with the Tax-Related Items (including if the
Consultant's cash compensation is not sufficient to satisfy such obligations).

8.   Data Privacy Consent.

     The Consultant hereby explicitly and unambiguously consents to the
collection, use and transfer, in electronic or other form, of the Consultant's
personal data as described in this document by and among, as applicable, the
Consultant, the Company and its subsidiaries and affiliates for the exclusive
purpose of implementing, administering and managing the Consultant's
participation in the Plan. The Consultant understands that the Company, its
affiliates and its subsidiaries hold certain personal information about the
Consultant, including,


                                        3

<PAGE>

but not limited to, name, home address and telephone number, date of birth,
social security or insurance number or other identification number, salary,
nationality, job title, any shares of stock or directorships held in the
Company, details of all options or any other entitlement to shares of stock
awarded, canceled, purchased, exercised, vested, unvested or outstanding in the
Consultant's favor for the purpose of implementing, managing and administering
the Plan ("Data"). The Consultant understands that the Data may be transferred
to any third parties assisting in the implementation, administration and
management of the Plan, that these recipients may be located in the Consultant's
country or elsewhere and that the recipient country may have different data
privacy laws and protections than the Consultant's country. The Consultant
understands that the Consultant may request a list with the names and addresses
of any potential recipients of the Data by contacting the administrator of the
Plan as may be designated from time to time by the Company (the "Plan
Administrator"). The Consultant authorizes the recipients to receive, possess,
use, retain and transfer the Data, in electronic or other form, for the purposes
of implementing, administering and managing the Consultant's participation in
the Plan, including any requisite transfer of such Data, as may be required to a
broker or other third party with whom the Consultant may elect to deposit any
Common Stock acquired under the Plan. If the Consultant is a citizen or resident
of a country which is a member of the European Union, the Data will only be
shared with third parties that are subject to the EU Privacy directive as
locally implemented, the Safe Harbor framework or other adequate certification.
The Consultant understands that Data will be held only as long as is necessary
to implement, administer and manage participation in the Plan. The Consultant
understands that he or she may, at any time, review Data in order to correct,
change or delete inaccurate information, request additional information about
the storage and processing of the Data, require any necessary amendments to the
Data or refuse or withdraw the consents herein, in any case without cost, by
contacting the Plan Administrator in writing. The Consultant understands that
refusing or withdrawing consent may affect the Consultant's ability to
participate in the Plan. For more information on the consequences of refusing to
consent or withdrawing consent, the Consultant understands that he or she may
contact the Plan Administrator at the Company.

9.   Plan Information.

     The Consultant acknowledges that the Consultant has access to and is deemed
to have received a copy of the Plan from the Company and agrees to receive
stockholder information, including copies of any annual report, proxy statement
and periodic report, from the Company's website at
http://www.osteotech.com/finreq.htm. The Consultant acknowledges that copies of
the Plan, Plan prospectus, Plan information and stockholder information are also
available upon written or telephonic request to the Plan Administrator.

10.  Consultant Acknowledgments.

     By accepting this grant of Stock Units, the Consultant acknowledges and
agrees that the Plan is established voluntarily by the Company, it is
discretionary in nature and may be modified, amended, suspended or terminated by
the Company at any time unless otherwise provided in the Plan or this Agreement.
The Consultant acknowledges that all decisions with respect to future grants, if
any, will be at the sole discretion of the Company. The Consultant's
participation in the Plan shall not create a right to further service with the
Company and shall not


                                        4

<PAGE>

interfere with the ability of the Company to terminate the Consultant's service
relationship with the Company at any time with or without cause and it is
expressly agreed and understood that the service relationship is terminable at
the will of either party, insofar as permitted by law. The Consultant agrees
that Stock Units, stock unit grants and resulting benefits are an extraordinary
item that do not constitute compensation of any kind for services of any kind
rendered to the Company and are outside the scope of the Consultant's service
contract, if any. Stock Units, stock unit grants and resulting benefits are not
part of normal or expected compensation or salary for any purposes, including,
but not limited to calculating any severance, resignation, termination,
redundancy, end of service payments, bonuses, long-service awards, pension or
retirement benefits or similar payments insofar as permitted by law. This grant
of Stock Units will not be interpreted to form a service contract or
relationship with the Company or any subsidiary or affiliate of the Company. The
Consultant acknowledges that the future value of the Shares is unknown, may
increase or decrease from the date of grant or vesting of the Stock Units and
cannot be predicted with certainty. In consideration of this grant of Stock
Units, no claim or entitlement to compensation or damages shall arise from
termination of this grant of Stock Units or diminution in value of this grant of
Stock Units resulting from the Consultant's termination with the Company for any
reason whatsoever and whether or not in breach of any applicable laws. Upon the
Consultant's termination of service with the Company (whether or not such
termination constitutes a breach of local labor laws), the Consultant's right to
receive benefits shall be only as set forth in this Agreement and his or her
termination will not be extended by any notice period mandated under local law
(e.g., active employment would not include a period of "garden leave" or similar
period pursuant to local law); and the Board or Compensation Committee shall
have the exclusive discretion to determine when the Consultant is terminated for
purposes of this grant of Stock Units. This entire Section 10 is subject to any
provision to the contrary set forth in a consulting contract, if any, between
the Consultant and the Company.

11.  Notices.

     All notices or other communications which are required or permitted
hereunder shall be deemed to be sufficient if contained in a written instrument
given by personal delivery, air courier or registered or certified mail, postage
prepaid, return receipt requested, addressed to such party at the address set

     If to the Consultant, to:

          Address provided above

     All such notices, advances and communications shall be deemed to have been
delivered and received (a) in the case of personal delivery, on the date of such
delivery, (b) in the case of


                                        5

air courier, on the business day after the date when sent and (c) in the case of
mailing, on the third business day following such mailing.

12.  Miscellaneous.

     (a) The Company shall not be required to treat as the owner of Stock Units,
and associated benefits hereunder, any transferee to whom such Stock Units or
benefits shall have been so transferred in violation of this Agreement.

     (b) The Consultant shall take whatever additional actions and execute
whatever additional documents the Company may deem necessary or advisable in
order to carry out or effect one or more of the obligations or restrictions
imposed on the Consultant pursuant to the express provisions of this Agreement.

     (c) The Plan is incorporated herein by reference. The Stock Units are
issued pursuant to the Plan and are subject to its terms. No waiver or breach of
any condition of this Agreement shall be deemed to be a waiver of any other or
subsequent breach of condition, whether of like or different nature. This
Agreement is governed by the laws of the state of Delaware. In the event of any
conflict between the terms and provisions of the Plan and this Agreement, the
Plan terms and provisions shall govern. Capitalized terms used but not defined
in this Agreement have the meanings assigned to them in the Plan. Certain other
important terms governing this Agreement are contained in the Plan. This
Agreement may be executed in counterparts, each of which shall be deemed to be
an original, but all of which together shall constitute one and the same
instrument.

     (d) The provisions of this Agreement are severable and if any one or more
provisions are determined to be illegal or otherwise unenforceable, in whole or
in part, the remaining provisions shall nevertheless be binding and enforceable.

     (e) This Agreement constitutes the entire agreement between the parties
with respect to the subject matter hereof and thereof, merging any and all prior
agreements.

     (f) To the extent the Company determines that this Agreement is subject to
Code Section 409A, but does not conform with the requirements thereof, the
Company may at its sole discretion amend or replace the Agreement to cause the
Agreement to comply with Code Section 409A.

     (g) To the extent that the Company in good faith determines that any
payment provided for hereunder (meaning, the vesting and obligation to issue any
Shares hereunder) constitutes a "deferral of compensation" and that the
Consultant is a "key employee" (in each case as such terms are defined under
Code Section 409A), no amounts shall be payable to the Consultant pursuant
hereto prior to the earliest of (a) the Consultant's death following the date of
Consultant's termination of services to the Company, or (b) the date that is six
months following the date of the Consultant's "separation from service" with the
Company (within the meaning of Code Section 409A).
