Exhibit 10.61

                           CHANGE IN CONTROL AGREEMENT

            AGREEMENT by and between Osteotech, Inc., a Delaware corporation
(the "Company"), and ____________ (the "Executive"), dated as of the ___ day of
_________________, 2002.

            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 purposes of this
definition, Executive's "Compensation" shall mean the sum of the Executive's
base salary plus any cash bonuses included in Executive's taxable compensation
for federal income tax purposes and reported to Executive and Internal Revenue
Service ("IRS"). Compensation shall not include any amount, other than base
salary and cash bonuses, such as the reporting of previously deferred
compensation or gain realized upon exercise of any non qualified stock options.

            (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

            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 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
            Securities Exchange Act of 1934, as amended (the "Exchange Act") (a
            "Person") of beneficial ownership (within the meaning of Rule 13d-3
            promulgated under the Exchange Act) of a majority of the then
            outstanding voting securities of the Company (the "Outstanding
            Company Voting Securities"); provided, however, that the following
            acquisitions shall not constitute a Change in Control: (A) any
            acquisition by the Company, or (B) any acquisition by any employee
            benefit plan (or related trust) sponsored or maintained by the
            Company or any corporation controlled by the Company, or (C) any
            public offering, private placement or other issuance by the Company
            of its voting securities; or

                  (iii) a merger or consolidation of the Company with another
            entity in which neither the Company nor a corporation that, prior to

            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


                                       2

            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).

            in accordance with their terms immediately prior to the effective

<PAGE>

            effective date), notwithstanding anything to the contrary contained
            in the option certificates or any plan covering the Options

            Plan")) pursuant to the 2000 Plan (an "Award Agreement") and not the
            terms of this Agreement shall govern with respect to such options or

3. Termination of Employment.

            (a) Death or Disability. The Executive's employment shall terminate

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

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 6(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 6(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

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


                                       6
<PAGE>

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.

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


                                       8
<PAGE>

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 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, and his immediate family, as
the case may be, with the benefits provided by Section 4(b)(ii).

            (d) Additional Payment. Upon a Change in Control, Executive shall be
entitled to a payment (the "Additional Payment") equal to the product of (A)
[__________] 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) $8.50. 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.

5. 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,


                                       9

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.

6. 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.

by Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

8. Miscellaneous.

            This Agreement may not be waived, 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
its Board. The failure of either party to this Agreement to object to any breach
by the other party or the non-breaching party's conduct or forbearance shall not
constitute a waiver of that party's rights to enforce this Agreement. No waiver
by either party hereto at any time of any breach by the other party hereto of,
or compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of any subsequent breach by such
other party or any similar or dissimilar provisions or conditions at the same or
any prior or subsequent time. Except for that certain employment agreement dated
as of [________________ __, 20__] and entered into by and between the Company
and the Executive (the "Employment Agreement"), [the Option Agreement] and any
Award Agreement, no agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement. The Company and
Executive agree that to the extent any of the terms of the Employment Agreement
and this Agreement conflict, it is their intention that Executive in each case
receive the benefits under that agreement which are most favorable to the

Agreement that relate to a Change in Control (as defined in this Agreement)
shall be controlling over the terms of the Employment Agreement that relate to a
Change in Control. It is expressly agreed that the terms of the Option Agreement
and any Award Agreement (the "Stock Incentive Agreements") relating to the
vesting and exercise of any option or Award represented by such Stock Incentive
Agreements shall be controlling over the terms of this Agreement that relate to
the vesting and exercise of options and Awards. The validity, interpretation,
construction and performance of this Agreement shall be governed by the internal
laws of the State of New Jersey, without giving any effect to any conflict of
laws.

of this Agreement.

the term of this Agreement.
