                            FALCONSTOR SOFTWARE, INC.
                  2005 KEY EXECUTIVE SEVERANCE PROTECTION PLAN

                        EFFECTIVE AS OF DECEMBER 1, 2005

     WHEREAS, the Board of Directors of FalconStor Software, Inc., recognizes
that the threat of a change in ownership or control of the Company may occur
which can result in significant distractions of its key executive personnel
because of the uncertainties inherent in such a situation; and

     WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its stockholders to retain the services of its key
executive personnel in the event of a threat of a Change in Control of the
Company and to ensure their continued dedication and efforts in such event
without undue concern for their personal financial and employment security.

     NOW, THEREFORE, in order to fulfill the above purposes, the following plan
has been developed and is hereby adopted.

                         SECTION 1 ESTABLISHMENT OF PLAN

     As of the Effective Date, the Company hereby establishes a severance
compensation plan known as the FalconStor Software, Inc. 2005 Key Executive
Severance Protection Plan as set forth in this document.

                              SECTION 2 DEFINITIONS

     As used herein the following words and phrases shall have the following
respective meanings unless the context clearly indicates otherwise.

2.1  BASE SALARY

     As to any Participant the amount that the Participant is entitled to
receive as wages or salary from his or her Employer on an annualized basis, as
in effect immediately prior to a Change in Control or, if greater, at any time
following the Change in Control.

2.2  BOARD

     The Board of Directors of the Company.

2.3  BONUS AMOUNT

     The term "Bonus Amount" shall mean for any Participant the highest annual
bonus paid or payable to the Participant in respect of any of the three (3)
fiscal years of the Company preceding the Participant's termination of
employment

2.4  CAUSE



     "Cause" for termination by the Employer of the Participant's employment
shall mean (i) willful and continued failure by the Participant to substantially
perform the Participant's duties on behalf of the Employer (other than any such
failure resulting from the Participant's incapacity due to physical or mental
illness or any such actual or anticipated failure after the issuance of a Notice
of Termination for Good Reason by the Participant) for a period of at least
thirty consecutive days after a written demand for substantial performance has
been delivered to the Participant by the Responsible Person, which demand
specifically identifies the manner in which the Responsible Person believes that
the Participant has not substantially performed the Participant's duties, (ii)
willful misconduct or gross negligence by the Participant which is demonstrably
and materially injurious to the Company or any of its subsidiaries, or (iii) the
Participant is convicted of, or has entered a plea of NOLO CONTENDERE to, (x) a
felony or (y) any crime (whether or not a felony) involving dishonesty, fraud,
embezzlement or breach of trust. For purposes of clauses (i) and (ii) of this
definition, an act, or failure to act, on the Participant's part shall not be
deemed "willful" if done, or omitted to be done, by the Participant in good
faith and with reasonable belief that the Participant's act, or failure to act,
was in the best interest of the Company. In addition, as to any Participant who
is an Executive Officer, the Participant shall not be deemed to have been
terminated for Cause unless and until there shall have been delivered to the
Participant a copy of a resolution duly adopted by the affirmative vote of not
less than three-quarters of the entire membership of the Board at a meeting of
the Board (after reasonable notice to the Participant and an opportunity for the
Participant, together with the Participant's counsel, to be heard before the
Board), finding in good faith that the Participant has committed Cause as set
forth in such clauses and specifying the circumstances constituting Cause. For
purposes of this definition, "Responsible Person" shall mean (i) for a
Participant who is an Executive Officer, the Board, and (ii) for a Participant
who is an Other Executive, the Executive Officer to whom the Participant
ultimately reports.

2.5  CHANGE IN CONTROL

     A "Change in Control" shall mean the occurrence of any of the following
after the Effective Date:

     (a) An acquisition (other than directly from the Company) of any voting
securities of the Company (the "Voting Securities") by any "Person" (as the term
"person" is used for purposes of Section 13(d) or 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), immediately after which
such Person has "Beneficial Ownership" (within the meaning of Rule 13d-3
promulgated under the Exchange Act) of more than fifty percent (50%) of (1) the
then-outstanding shares of common stock of the Company (or any other securities
into which such shares of common stock are changed or for which such shares of
common stock are exchanged) (the "Shares") or (2) the combined voting power of
the Company's then-outstanding Voting Securities; PROVIDED, HOWEVER, that in
determining whether a Change in Control has occurred pursuant to this paragraph
(a), the acquisition of Shares or Voting Securities in a "Non-Control
Acquisition" (as hereinafter defined) shall not constitute a Change in Control.
A "Non-Control Acquisition" shall mean an acquisition by (i) an employee benefit


                                       2


plan (or a trust forming a part thereof) maintained by (A) the Company or (B)
any corporation or other Person the majority of the voting power, voting equity
securities or equity interest of which is owned, directly or indirectly, by the
Company (for purposes of this definition, a "Related Entity"), (ii) the Company
or any Related Entity, or (iii) any Person in connection with a "Non-Control
Transaction" (as hereinafter defined);

     (b) The individuals who, as of the Effective Date, are members of the board
of directors of the Company (the "Incumbent Board"), cease for any reason to
constitute at least a majority of the members of the board of directors of the
Company or, following a Merger (as hereinafter defined), the board of directors
of (x) the corporation resulting from such Merger (the "Surviving Corporation"),
if fifty percent (50%) or more of the combined voting power of the
then-outstanding voting securities of the Surviving Corporation is not
Beneficially Owned, directly or indirectly, by another Person (a "Parent
Corporation") or (y) if there is one or more than one Parent Corporation, the
ultimate Parent Corporation; PROVIDED, HOWEVER, that, if the election, or
nomination for election by the Company's common stockholders, of any new
director was approved by a vote of at least two-thirds of the Incumbent Board,
such new director shall, for purposes of the Plan, be considered a member of the
Incumbent Board; and PROVIDED, FURTHER, HOWEVER, that no individual shall be
considered a member of the Incumbent Board if such individual initially assumed
office as a result of an actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the board of directors of the
Company (a "Proxy Contest"), including by reason of any agreement intended to
avoid or settle any Proxy Contest; or

     (c) The consummation of:

          (i) A merger, consolidation or reorganization (1) with or into the
Company or (2) in which securities of the Company are issued (a "Merger"),
unless such Merger is a "Non-Control Transaction." A "Non-Control Transaction"
shall mean a Merger in which:

               (A) the stockholders of the Company immediately before such
     Merger own directly or indirectly immediately following such Merger at
     least fifty percent (50%) of the combined voting power of the outstanding
     voting securities of (x) the Surviving Corporation, if there is no Parent
     Corporation or (y) if there is one or more than one Parent Corporation, the
     ultimate Parent Corporation;

               (B) the individuals who were members of the Incumbent Board
     immediately prior to the execution of the agreement providing for such
     Merger constitute at least a majority of the members of the board of
     directors of (x) the Surviving Corporation, if there is no Parent
     Corporation, or (y) if there is one or more than one Parent Corporation,
     the ultimate Parent Corporation; and

               (C) no Person other than (1) the Company, (2) any Related Entity,
     or (3) any employee benefit plan (or any trust forming a part thereof)
     that, immediately prior to the Merger, was maintained by the Company or any


                                       3


     Related Entity, or (4) any Person who, immediately prior to the Merger had
     Beneficial Ownership of twenty percent (20%) or more of the then
     outstanding Shares or Voting Securities, has Beneficial Ownership, directly
     or indirectly, of twenty percent (20%) or more of the combined voting power
     of the outstanding voting securities or common stock of (x) the Surviving
     Corporation, if fifty percent (50%) or more of the combined voting power of
     the then outstanding voting securities of the Surviving Corporation is not
     Beneficially Owned, directly or indirectly by a Parent Corporation, or (y)
     if there is one or more than one Parent Corporation, the ultimate Parent
     Corporation;

               (ii) A complete liquidation or dissolution of the Company; or

               (iii) The sale or other disposition of all or substantially all
of the assets of the Company and its subsidiaries taken as a whole to any Person
(other than (x) a transfer to a Related Entity, (y) a transfer under conditions
that would constitute a Non-Control Transaction, with the disposition of assets
being regarded as a Merger for this purpose or (z) the distribution to the
Company's stockholders of the stock of a Related Entity or any other assets).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person (the "Subject Person") acquired Beneficial Ownership
of more than the permitted amount of the then outstanding Shares or Voting
Securities as a result of the acquisition of Shares or Voting Securities by the
Company which, by reducing the number of Shares or Voting Securities then
outstanding, increases the proportional number of shares Beneficially Owned by
the Subject Persons; PROVIDED, that if a Change in Control would occur (but for
the operation of this sentence) as a result of the acquisition of Shares or
Voting Securities by the Company and, after such share acquisition by the
Company, the Subject Person becomes the Beneficial Owner of any additional
Shares or Voting Securities and such Beneficial Ownership increases the
percentage of the then outstanding Shares or Voting Securities Beneficially
Owned by the Subject Person, then a Change in Control shall occur.

assignment to the Participant of any duties or responsibilities which, in the
Participant's reasonable judgment, are inconsistent with such status, title,

Severance Benefits have been paid to him or her.

                          SECTION 4 SEVERANCE BENEFITS

4.1  RIGHT TO SEVERANCE BENEFITS

     (a) A Participant shall be entitled to receive from the Company a Severance
Benefit in the amount provided in Section 4.2 if (i) a Change in Control has
occurred and (ii) within two years thereafter, the Participant's employment with
the Company terminates for any reason, except that notwithstanding the
provisions of this Section 4.1(a), no benefits under this Plan will be payable
should the Participant's termination of employment be (A) by the Employer for
Cause, (B) by reason of Permanent Disability, (C) voluntarily initiated by the
Participant other than for Good Reason, or (D) by reason of the Participant's
death.

     (b) If (i) a Participant's employment is terminated by the Employer without
Cause prior to the date of a Change in Control or (ii) an action is taken with
respect to the Participant prior to the date of a Change in Control that would
constitute Good Reason if taken after a Change in Control, and the Participant
reasonably demonstrates that such termination or action (A) was at the request
of a third party that has indicated an intention or taken steps reasonably
calculated to effect a Change in Control or (B) otherwise arose in connection
with, or in anticipation of, a Change in Control that has been threatened or
proposed, such termination or action shall be deemed to have occurred after such
Change in Control for purposes of the Plan, so long as such Change in Control
actually occurs.

     (c) Notwithstanding any other provision of the Plan, the sale, divestiture
or other disposition of an Operating Company (or part thereof) before the
execution of an agreement providing for a transaction or transactions which, if
consummated, would constitute a Change in Control or before a Change in Control
shall not be deemed to be a termination of employment of Participants employed
by such Operating Company, and such Participants shall not be entitled to
benefits from the Company under this Plan as a result of such sale, divestiture
or other disposition. The sale, divestiture or other disposition of an Operating


                                       7


Company (or part thereof) after the execution of an agreement providing for a
transaction or transactions which, if consummated, would constitute a Change in
Control or after a Change in Control shall not be deemed to be a termination of
employment of Participants employed by such Operating Company, and such
Participants shall not be entitled to benefits from the Company under this Plan
as a result of such sale, divestiture or other disposition, in each case so long
as the provisions of Section 7.2 have been satisfied.

4.2  AMOUNT OF SEVERANCE BENEFIT

     If a Participant's employment is terminated in circumstances entitling him
or her to a Severance Benefit as provided in Section 4.1, such Participant shall
be entitled to the following benefits:

          (a) the Company shall pay to the Participant, as severance pay and in
lieu of any further salary for periods subsequent to the Termination Date (as
specified in Section 5.2), in a single payment (without any discount for
accelerated payment), an amount in cash equal to a formula, as described below,
and based upon a multiplier, as assigned in the table below to the Participant
according to the Participant's designation on Exhibit II ("Participant
Designation"):

           Multiplier     Participant Designation
           ----------     -----------------------
           3 X            Group III
           2 X            Group II
           1 X            Group I

     (X) times the sum of (A) the Participant's Base Salary and (B) the Bonus
Amount, plus the prorated portion of the Participant's Bonus Amount for the year
in which the Participant's employment is terminated;

          (b) for the period of months, as specified for each Participant
Designation Level in the table below, subsequent to the Participant's
termination of employment, the Company shall at its expense continue on behalf
of the Participant and his or her dependents and beneficiaries, the basic life
insurance, flexible spending account, medical and dental benefits which were
being provided to the Participant immediately prior to the Change in Control
(or, if greater, at any time thereafter). The benefits provided in this
Subsection 4.2(b) shall be no less favorable to the Participant, in terms of
amounts and deductibles and costs to him or her, than the coverage provided the
Participant under the plans providing such benefits at the time Notice of
Termination is given. The Company's obligation hereunder to provide the
foregoing benefits shall terminate to the extent the Participant obtains
replacement coverage under a subsequent employer's benefit plans at an equal or
higher level. The Company also shall pay a lump sum equal to the amount of any
additional income tax payable by the Participant and attributable to the
benefits provided under this subparagraph (b) at the time such tax is imposed
upon the Participant;

                                       8


     Number of Months of
     Continued Coverage        Participant Designation
     ------------------        -----------------------
     36 months                 Group III
     24 months                 Group II
     12 months                 Group I

     The amounts provided for in Section 4.2(a) shall be paid or transferred
within thirty (30) days after the Participant's termination of employment (or,
if Section 4.1(b) applies to the termination, then within 30 days after the
Change in Control).

4.3  OPTIONS

     Notwithstanding any provision in the Company's 2000 Stock Option Plan, as
amended, or any other Company Incentive or Non-Qualified Stock Option Plan, or
in this Plan, in the event there is a Change of Control, the Company shall, at
no cost to the Participant, replace any and all stock options granted by the
Company and held by the Participant at the time of the Change of Control,
whether or not vested, with an equal number of unrestricted and fully vested
stock options to purchase shares of the Company's Common Stock (the "Option
Replacement"). With respect to the Option Replacement, all options will become
fully vested.

     Alternatively, in the event of a Change of Control, in lieu of the Option
Replacement, a Participant may elect to surrender the Participant's rights to
such options, and upon such surrender, the Company shall pay to the Participant
an amount in cash per stock option (whether vested or unvested) then held, which
is the difference between the full exercise price of each option surrendered and
the greater of (i) the average price per share paid in connection with the
acquisition of control of the Company if such control was acquired by the
payment of cash or the then fair market value of the consideration paid for such
shares if such control was acquired for consideration other than cash, (ii) the
price per share paid in connection with any tender offer for shares of the
Company's Common Stock leading to control, or (iii) the mean between the high
and low selling price of such stock on the Nasdaq National Market or other
market on which the Company's Common Stock is then traded on the date on which
the Participant entitled to a Severance Benefit.


                       SECTION 5 TERMINATION OF EMPLOYMENT

5.1  WRITTEN NOTICE REQUIRED

Participant, shall be communicated by written Notice of Termination to the
other.

5.2  TERMINATION DATE

     In the case of the Participant's death, the Participant's Termination Date
shall be his her date of death. In all other cases, the Participant's
Termination Date shall be the date specified in the Notice of Termination
subject to the following:

          (a) If the Participant's employment is terminated by the Company for
Cause or due to Permanent Disability, the date specified in the Notice of
Termination shall be at least thirty (30) days from the date the Notice of
Termination is given to the Participant, provided that in the case of Permanent
Disability the Participant shall not have returned to the full-time performance
of his or her duties during such period of at least thirty (30) days; and

          (b) If the Participant terminates his or her employment for Good
Reason, the date specified in the Notice of Termination shall not be more than
sixty (60) days from the date the Notice of Termination is given to the Company.

                  SECTION 6 ADDITIONAL PAYMENTS BY THE COMPANY

6.1   GROSS-UP PAYMENT

     (a) Other than Severance Benefits due under Section 4.3, hereof, and
subject only to Section 6.1(b) hereof, in the event it shall be determined that
any payment or distribution of any type by the Company or any of its affiliates
to or for the benefit of the Participant, whether paid or payable or distributed
or distributable pursuant to the terms of this Plan or otherwise (the
"Payments"), would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code"), or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest and penalties, are collectively referred to as the "Excise Tax"),
then the Participant shall be entitled to receive an additional payment (a
"Gross-Up Payment") in an amount such that after payment by the Participant of
all taxes (including any interest or penalties imposed with respect to such
taxes), including any income taxes, employment taxes and Excise Tax, imposed
upon the Gross-Up Payment, the Participant retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payments. Payment of the
Gross-Up Payment shall be made in accordance with Section 6.3.

     (b) Notwithstanding Section 6.1(a), in the event that a reduction to the
Payments in respect of a Participant of 10% or less would cause no Excise Tax to
be payable, the Participant will not be entitled to a Gross-Up Payment and the
Payments shall be reduced (but not below zero) to the extent necessary so that
the Payments shall not be subject to the Excise Tax. Unless the Participant
shall have given prior written notice specifying a different order to the
Company to effectuate the foregoing, the Company shall reduce or eliminate the
Payments, by first reducing or eliminating the portion of the Payments which are
not payable in cash and then by reducing or eliminating cash payments, in each
case in reverse order beginning with payments or benefits which are to be paid


                                       10


the farthest in time from the date of the Change in Control. Any notice given by
the Participant pursuant to the preceding sentence shall take precedence over
the provisions of any other plan, arrangement or agreement governing the
Participant's rights and entitlements to any benefits or compensation.

6.2  DETERMINATION BY ACCOUNTANT

     All determinations required to be made under this Section 6, including
whether a Gross-Up Payment is required and the amount of such Gross-Up Payment,
shall be made by the independent accounting firm retained by the Company on the
date of Change in Control (the "Accounting Firm"), which shall provide detailed
supporting calculations both to the Company and the Participant within 15
business days of the date of termination, if applicable, or such earlier time as
is requested by the Company. If the Accounting Firm determines that no Excise
Tax is payable by the Participant, it shall furnish the Participant with an
opinion that he or she has substantial authority not to report any Excise Tax on
his or her federal income tax return. Any determination by the Accounting Firm
shall be binding upon the Company and the Participant. As a result of the
uncertainty in the application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is possible that
Gross-Up payments which will not have been made by the Company should have been
made ("Underpayment"), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to
Section 6.3 and the Participant thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of the Participant.

6.3  NOTIFICATION REQUIRED

     The Participant shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by the
Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable but no later than ten (10) business days after the Participant knows
of such claim and shall apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid. The Participant shall not pay
such claim prior to the expiration of the thirty (30) day period following the
date on which it gives such notice to the Company (or such shorter period ending
on the date that any payment of taxes with respect to such claim is due). If the
Company notifies the Participant in writing prior to the expiration of such
period that it desires to contest such claim, the Participant shall:

          (a) give the Company any information reasonably requested by the
     Company relating to such claim,

          (b) take such action in connection with contesting such claim as the
     Company shall reasonably request in writing from time to time, including,
     without limitation, accepting legal representation with respect to such
     claim by an attorney reasonably selected by the Company,

                                       11


          (c) cooperate with the Company in good faith in order to effectively
     contest such claim, and

          (d) permit the Company to participate in any proceedings relating to
     such claim; PROVIDED, HOWEVER, that the Company shall bear and pay directly
     all costs and expenses (including additional interest and penalties)
     incurred in connection with such contest and shall indemnify and hold the
     Participant harmless, on an after-tax basis, for any Excise Tax or income
     tax, including interest and penalties with respect thereto, imposed as a
     result of such representation and payment of costs and expenses. Without
     limitation on the foregoing provisions of this Section 6.3, the Company
     shall control all proceedings taken in connection with such contest and, at
     its sole option, may pursue or forgo any and all administrative appeals,
     proceedings, hearings and conferences with the taxing authority in respect
     of such claim and may, at its sole option, either direct the Participant to
     pay the tax claimed and sue for a refund, or contest the claim in any
     permissible manner, and the Participant agrees to prosecute such contest to
     a determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Company shall
     determine; PROVIDED, HOWEVER, that if the Company directs the Participant
     to pay such claim and sue for a refund, the Company shall advance the
     amount of such payment to the Participant (unless otherwise prohibited by
     applicable law), on an interest-free basis and shall indemnify and hold the
     Participant harmless, on an after-tax basis, from any Excise Tax or income
     tax, including interest or penalties with respect thereto, imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and PROVIDED, FURTHER, that any extension of the statute
     of limitations relating to payment of taxes for the taxable year of the
     Participant with respect to which such contested amount is claimed to be
     due is limited solely to such contested amount. Furthermore, the Company's
     control of the contest shall be limited to issues with respect to which a
     Gross-Up Payment would be payable hereunder and the Participant shall be
     entitled to settle or contest, as the case may be, any other issue raised
     by the Internal Revenue Service or any other taxing authority.

6.4  REPAYMENT

     If, after the receipt by the Participant of an amount advanced by the
Company pursuant to Section 6.3, the Participant becomes entitled to receive any
refund with respect to such claim, the Participant shall (subject to the
Company's complying with the requirements of Section 6.3) promptly pay to the
Company the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto). If, after the receipt by the
Participant of an amount advanced by the Company pursuant to Section 6.3, a
determination is made that the Participant shall not be entitled to any refund
with respect to such claim and the Company does not notify the Participant in
writing of its intent to contest such denial of refund prior to the expiration
of thirty (30) days after such determination, then such advance shall be


                                       12


forgiven and shall not be required to be repaid and the amount of such advance
shall offset, to the extent thereof the amount of Gross-Up Payment required to
be paid.


                         SECTION 7 SUCCESSORS TO COMPANY

7.1  SUCCESSORS

     This Plan shall bind 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, in the same manner and to the same extent
that the Company would be obligated under this Plan if no succession had taken
place. In the case of any transaction in which a successor would not by the
foregoing provision or by operation of law be bound by this Plan, the Company
shall require such successor expressly and unconditionally to assume and agree
to perform the Company's obligations under this Plan, in the same manner and to
the same extent that the Company would be required to perform if no such
succession had taken place.

7.2  SALES OF OPERATING COMPANIES

     If a Participant's employment with his or her Employer terminates in
connection with the sale, divestiture or other disposition of the stock or
assets of any Operating Company (or part thereof) (a "Transaction") after the
execution of an agreement providing for a transaction or transactions which, if
consummated, would constitute a Change in Control or after a Change in Control,
such termination shall not be a termination of employment of the Participant for
purposes of the Plan, and (notwithstanding the rights provided to the
Participant by Section 4.1(a)) the Participant shall not be entitled to a
Severance Benefit as a result of such termination of employment if (i) the
Participant is offered continued employment, or continues in employment, with
the divested Operating Company (or part thereof) or the purchaser of the stock
or assets of the Operating Company (or part thereof), as the case may be, or one
of their respective affiliates (the "Post-Transaction Employer") on terms and
conditions that would not constitute Good Reason and (ii) the Company obtains an
agreement from the acquiror of the stock or assets of the divested Operating
Company (or part thereof), enforceable by the Participant, to provide or cause
the Post-Transaction Employer to provide severance pay and benefits, if the
Participant accepts the offered employment or continues in employment with the
Post-Transaction Employer or its affiliates following the Transaction, (A) at
least equal to the Severance Benefit and (B) payable upon a termination of the
Participant's employment with the Post-Transaction Employer and its affiliates
within the period described in Section 4.1(a)(ii) (or such part of it as is then
remaining) for any reason other than Cause, Permanent Disability, the
Participant's death or a termination by the Participant without Good Reason. For
purposes of this Section 7.2, the terms Cause, Good Reason and Permanent
Disability shall have the meanings ascribed to them in Sections 2.4, 2.10 and
2.15 respectively, but the term Employer as it is used in those Sections shall
be deemed to refer to the entity employing the Participant after the
Transaction, the term Company shall mean such employer or, if there is an


                                       13


ultimate parent corporation of such employer, such ultimate parent corporation,
and the terms Board and Chief Executive Officer as used in those Sections shall
be deemed to refer to the individuals or bodies serving those functions for such
employer or, if applicable, such ultimate parent corporation.

                    SECTION 8 AMENDMENT AND PLAN TERMINATION

8.1  AMENDMENT AND TERMINATION

     Prior to a Change in Control, the Plan may be amended or modified in any
respect, and may be terminated, in any such case, by resolution adopted by
two-thirds of the Board; PROVIDED, HOWEVER, that no such amendment, modification
or termination which would adversely affect the benefits or protections
hereunder of any individual who is a Participant as of the date such amendment,
modification or termination is adopted shall be effective as it relates to such
individual unless no Change in Control occurs within one year after such
adoption, any such attempted amendment, modification or termination adopted
within one year prior to a Change in Control being null and void ab initio as it
relates to all such individuals who were Participants prior to such adoption (it
being understood that the removal of Participants from participation in the Plan
shall, for purposes of this proviso, constitute an adverse action for the
Participants so removed); PROVIDED, further, HOWEVER, that the Plan may not be
amended, modified or terminated, (i) at the request of a third party who has
indicated an intention or taken steps to effect a Change in Control and who
effectuates a Change in Control or (ii) otherwise in connection with, or in
anticipation of, a Change in Control which actually occurs, any such attempted
amendment, modification or termination being null and void ab initio. Any action
taken to amend, modify or terminate the Plan which is taken after the execution
of an agreement providing for a transaction or transactions which, if
consummated, would constitute a Change in Control shall conclusively be presumed
to have been taken in connection with a Change in Control. From and after the
occurrence of a Change in Control, the Plan may not be amended or modified in
any manner that would in any way adversely affect the benefits or protections
provided hereunder to any individual who is a Participant in the Plan on the
date the Change in Control occurs.

8.2  FORM OF AMENDMENT

     The form of any amendment or termination of the Plan shall be a written
instrument signed by a duly authorized officer or officers of the Company,
certifying that the amendment or termination has been approved by the Board.

                             SECTION 9 MISCELLANEOUS

9.1  INDEMNIFICATION

     The Company shall pay as they become due all legal fees, costs of
litigation and other expenses incurred in good faith by any Participant as a
result of the Company's refusal or failure to provide the Severance Benefits to
which the Participant becomes entitled under this Agreement, as a result of the


                                       14


Company's contesting the validity, enforceability or interpretation of this
Agreement or the Participant's right to Severance Benefits hereunder. The
Participant shall be conclusively presumed to have acted in good faith unless a
court makes a final determination not otherwise subject to appeal to the
contrary.

9.2  EMPLOYMENT STATUS

     This Plan does not constitute a contract of employment or impose on any
Employer any obligation to retain the Participant as an employee, to change the
status of the Participant's employment as an Executive Officer or an Other
Executive, or to change any employment policies of any Employer. Without
limiting the generality of the immediately preceding sentence, the Employer of a
Participant may terminate the employment of the Participant at any time
following a Change in Control, with or without Cause, subject to Section 5
hereof.

9.3  NO DUTY OF MITIGATION

     The Company acknowledges that it would be very difficult and generally
impracticable to determine a Participant's ability to, or the extent to which a
Participant may, mitigate any damages or injuries the Participant may incur by
reason of the Change of Control. The Company has taken this into account in
adopting this Plan and, accordingly, the Company acknowledges and agrees that no
Participant shall have any duty to mitigate any such damages and that the
Participant shall be entitled to receive all Severance Benefits regardless of
any income which the Participant may receive from other sources following any
Change of Control.

9.4  NO SETOFF

     The Company's obligation to give Severance Benefits to a Participant
pursuant to this Plan and otherwise to perform its obligations hereunder shall
not be affected by any circumstances, including, but not limited to, any setoff,
counterclaim, recoupment, defense or other right which the Company may have
against a Participant.

9.5  BENEFITS UNDER OTHER PLANS

     The benefits that a Participant may be entitled to receive pursuant to
Section 4.2 of this Plan are not intended to be duplicative of any similar
benefits to which the Participant may be entitled from the Company under any
other severance plan, agreement, policy or program maintained by the Company or
any of its Subsidiaries. Accordingly, the benefits to which a Participant is
entitled under Section 4.2 shall be reduced to take account of any other similar
benefits to which the Participant is entitled from the Company; provided,
however, that if the amount of benefits to which the Participant is entitled
under such other severance plan, agreement, policy or program is greater than
the benefits to which the Participant is entitled under Section 4.2 of this


                                       15


Plan, the Participant will be entitled to receive the full amount of the
benefits to which the Participant is entitled under such other plan, agreement,
policy or program.

9.6  VALIDITY AND SEVERABILITY

     The invalidity or unenforceability of any provision of the Plan shall not
affect the validity or enforceability of any other provision of the Plan, which
shall remain in full force and effect, and any prohibition or unenforceability
in any jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

9.7  GOVERNING LAW; CHOICE OF FORUM

     The validity, interpretation, construction and performance of the Plan
shall in all respects be governed by the laws of the State of New York. A
Participant shall be entitled to enforce the provisions of this Plan in any
state or federal court located in the State of New York, in addition to any
other appropriate forum.

     IN WITNESS WHEREOF, the Company has caused the Plan to be effective as of
the Effective Date.
