     THIS AGREEMENT between CHAMPION INTERNATIONAL CORPORATION, a New York
corporation (the "Company"), and L. SCOTT BARNARD  (the "Executive"), effective
October 18, 1990 (the "Agreement").

                              W I T N E S S E T H:
     WHEREAS, the Executive is now in the employ of the Company; and
     WHEREAS, the Executive is Vice President - Printing Papers;  and
     WHEREAS, the Company wishes to provide additional incentive for the
Executive to continue in the employ of the Company;
     NOW, THEREFORE, it is hereby agreed by and between the parties as follows:
     1.  Termination
         -----------
     In the event of a termination, as defined in subparagraph 1(b) below, the
following provisions of this paragraph 1 shall apply.
      (a)  Termination Payments
           --------------------
      (i)  Monthly payments.  Subject to compliance with the applicable
           ----------------                                            
provisions of paragraph 3 below, the Company shall pay the Executive or, in the
event of his subsequent death, his beneficiary or beneficiaries or his estate,
as the case may be, as severance pay or liquidated damages, or both, a monthly
sum equal to the highest total monthly compensation (highest total of annual
salary plus annual bonus for any calendar year of employment, divided by
twelve), paid to the Executive.  Such payments shall commence on the last day of
the month next following the termination of employment of the Executive and
shall continue until the last day of the twenty-fourth full calendar month
following the termination of employment of the Executive, provided, however,
that such payments shall not continue beyond the earlier of (A) the last day of
the month next preceding his normal retirement date under the Company's pension
plan, and (B) the last day of the month next preceding the month in which he
shall, with his written consent, commence receiving his retirement allowance
under the Company's pension plan.
         (ii)  Lump Sum Payment upon Termination following a Change in Control.
               ---------------------------------------------------------------
Anything in subparagraph 1(a)(i) above or elsewhere in this Agreement to the
contrary notwithstanding, if termination of the Executive occurs within three
years following a Change in Control: (x) the total of the monthly payments
provided for in subparagraph 1(a)(i) above shall be accelerated and paid in a
lump sum as soon as practicable after such termination if termination occurs
before the last day of the month next preceding the Executive's normal
retirement date under the Company's pension plan; if termination occurs on or
after such last day, no payment pursuant to subparagraph 1(a)(i) or (ii) shall
be made to the Executive; (y) the benefits required to be provided thereafter to
the Executive, his spouse and family, set forth in attached Exhibit A, shall be
                                                            ---------          
valued at the cost of acquiring insurance policies which would provide such
benefit coverage over the period of time involved in subparagraph 1(a)(i) above,
and such cost shall be paid in a lump sum as soon as practicable after
termination; and (z) the Executive shall be paid the amount payable, if any,
pursuant to subparagraph 1(a)(iii) and the amount payable pursuant to
subparagraph 1(a)(iv).
         (iii)  Cash-Out of Options and Contingently Credited Shares.  In the
                ----------------------------------------------------         
event that the Executive shall, at the time of termination of his employment
within three years following a Change in Control, (A) hold an outstanding and
unexercised (whether or not exercisable at the time) option or options
theretofore granted by the Company to him prior to the Change in Control, (B)
have shares contingently credited to him prior to the Change in Control under
the Company's Contingent Compensation Plan or 1986 Contingent Compensation Plan
or a successor plan, or both hold such option and have such shares contingently
credited to him,
                                       1
<PAGE>
 
unless the Executive shall have given the Company written notice to the contrary
within thirty (30) days following such termination of employment, the Company
shall pay him, in a lump sum, an amount equal to the excess above the option
price, of each such option that is not an Incentive Stock Option as defined in
Section 422A of the Internal Revenue Code of 1986 as amended (the "Code"), of
the Fair Market Value of Company shares at the time of termination, and the Fair
Market Value at the time of termination of the shares, if any, so contingently
credited.  Solely for the purpose of this subparagraph 1(a)(iii), Fair Market
Value at the time of termination shall mean the higher of (i) the average of the
reported closing prices of the Common Shares of the Company, as reported in "New
York Stock Exchange Composite Transactions" of the Eastern Edition of The Wall
                                                                      --------
Street Journal, for the last trading day prior to the termination and for each
--------------                                                                
trading day of the preceding sixty calendar days, and (ii) in the event that a
Change in Control of the Company, as defined in subparagraph 1(d) below, shall
have taken place prior to termination as the result of a tender or exchange
offer, and such Change in Control was consummated within three years of
termination, an amount equal to the highest consideration paid for Common Shares
of the Company in the course of such tender or exchange offer.
         (iv)  Payment of Value of Excess Benefit and Supplement Retirement Plan
               -----------------------------------------------------------------
Payments Benefits.   Anything in this Agreement to the contrary notwithstanding,
-----------------                                                               
in the event of a termination of the Executive's employment within three years
following a Change in Control, the Executive shall be entitled to a monthly
retirement allowance for life payable on a straight life annuity basis, equal to
the benefit payable, if any, under the Company's excess benefit and supplemental
retirement plans, utilizing the monthly payments set forth in subparagraph
1(a)(i) above for purposes of the pension calculation for the termination period
set forth in such subparagraph 1(a)(i).  For the purposes of this clause (iv),
the excess benefit and supplemental retirement plans payments shall include the
pension enhancement resulting from service credit for pension benefit during the
termination period set forth in subparagraph 1(a)(i) above.  Such retirement
allowance shall be valued and discounted in the manner set forth in subparagraph
3(g) below relating to default in payments or benefits and shall be paid in a
lump sum as soon as practicable after such termination.
         (v)  Participation in Benefit Plans.   The Executive shall be eligible
              -------------------------------                                  
to receive, during any period that he shall be entitled to receive payments from
the Company under subparagraph 1(a)(i) above (whether or not any such period
shall be accelerated), as if the Executive had continued to be employed by the
Company during such period, any benefits and emoluments for which key executives
are eligible under any hospitalization, health care or dental care plan, life or
other insurance or death benefit plan, travel and accident insurance, executive
or contingent compensation plan, restricted stock or stock purchase plan,
retirement income or pension plan, vacation plan, or other present or future
employee benefit plans or programs of the Company for which key executives are
eligible, in accordance with the provisions of any such plan or program,
provided, however, that during the period that the Executive is so entitled to
receive payments under subparagraph 1(a)(i) above, he shall not be eligible to
participate in the Company's Savings Plan for Salaried Employees or to receive
option grants under any stock option plan of the Company.  Nothing in this
Agreement shall preclude the Company from terminating or amending any such
employee benefit plan or program so as to eliminate, reduce or otherwise change
any benefit payable thereunder.  To the extent that such benefits or service
credits for benefits shall not be payable or provided under such plans or
programs by reason of the Executive no longer being an employee of the Company,
the Company shall itself pay or provide for payment of such benefits and service
credit for benefits.

       (b)  Definition of Termination
            -------------------------
     The term "termination" for purposes of this Agreement shall mean:
         (i)  The termination by the Company of the Executive's full-time
employment with the Company for any reason other than Cause; or
         (ii) Any (A) failure to appoint or re-appoint or elect or re-elect the
Executive to an office and position at least equal to the office and position he
held immediately prior to such failure, or removal of the Executive from such
office or position, (B) material change by the Company of the Executive's
functions, duties or responsibilities without his express written consent as a
result of which change the Executive's position with the Company shall be or
become of less dignity, responsibility, importance or scope than the position he
held at the time of such material change, and any such material change shall be
deemed a continuing breach of this Agreement, (C) reduction in the monthly base
salary of the Executive below the highest monthly base salary paid from and
after October 18, 1990, (D) liquidation, dissolution, consolidation or merger of
the Company, or transfer of all or substantially all of its assets, other than
in compliance with the provisions of paragraph 8 below, or (E) breach of this
Agreement by the Company, or breach of the Agreement Relating to Legal Expenses
between the Company and the Executive dated October 18, 1990 (the "Legal Expense
Agreement"); provided that in any such event the Executive elects to terminate
his employment under this Agreement upon not less than sixty days' advance
written notice given within a reasonable period of time not to exceed, except in
case of a continuing breach, four calendar months after the event giving rise to
the election.
       (c)  Definition of Cause
            -------------------
     For the purpose of any provision of this Agreement, the termination of the
Executive's employment shall be deemed to have been for Cause only if
termination of his employment shall have been the result of an act or acts of
dishonesty on the part of the Executive constituting a felony and resulting or
intended to result directly or indirectly in gain or personal enrichment at the
expense of the Company; provided that there shall have been delivered to the
Executive a certified copy of a resolution of the Board of Directors of the
Company adopted by the affirmative vote of not less than three-fourths of the
entire membership of the Board of Directors at a meeting called and held for
that purpose and at which the Executive was given an opportunity to be heard,
finding that the Executive was guilty of such conduct, specifying the
particulars thereof in detail.
     Anything in this subparagraph 1(c) or elsewhere in this Agreement to the
contrary notwithstanding, the employment of the Executive shall in no event be
considered to have been terminated by the Company for Cause if termination of
his employment took place (A) as the result of bad judgment or negligence on the
part of the Executive, or (B) as the result of an act or omission without intent
of gaining therefrom directly or indirectly a profit to which the Executive was
not legally entitled, or (C) because of an act or omission believed by the
Executive in good faith to have been in or not opposed to the interests of the
Company, or (D) for any act or omission in respect of which a determination
could properly be made that the Executive met the applicable standard of conduct
prescribed for indemnification or reimbursement or payment of expenses under (I)
the Restated Certificate of Incorporation or By-Laws of the Company, or (II) the
laws of the State of New York, or (III) the directors' and officer's liability
insurance of the Company, in each case either as in effect at the time of this
Agreement or in effect at the time of such act or omission, or (E) as the result
of an act or omission which occurred more than twelve calendar months prior to
the Executive's having been given notice of the termination of his employment
for such act or omission unless the commission of such act or such omission
could not at the time of such commission or

                                       3
<PAGE>
 
omission have been known to a member of the Board of Directors of the Company
(other than the Executive, if he is then a member of the Board of Directors), in
which case more than twelve calendar months from the date that the commission of
such act or such omission was or could reasonably have been so known, or (F) as
the result of a continuing course of action which commenced and was or could
reasonably have been known to a member of the Board of Directors of the Company
(other than the Executive, if he is then a member of the Board of Directors)
more than twelve calendar months prior to notice having been given to the
Executive of the termination of his employment.
       (d)  Definition of Change in Control
            -------------------------------
          For the purpose of this Agreement, a Change in Control of the Company
shall be deemed to have occurred if
          (i)  any "person" (as defined in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), other than a
trustee or other fiduciary holding securities under an employee benefit plan of
the Company, is or becomes the "beneficial owner" (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Company
representing thirty percent (30%) or more of the combined voting power of the
Company's then outstanding securities;
         (ii)  during any period within two (2) consecutive years there shall
cease to be a majority of the Board of Directors comprised as follows:
individuals who at the beginning of such period constitute the Board of
Directors and any new director(s) whose election by the Board of Directors or
nomination for election by the Company's shareholders was approved by a vote of
at least two-thirds (2/3) of the directors then still in office who either were
directors at the beginning of the period or whose election or nomination for
election was previously so approved; or

substantially all the Company's assets.
     2.  Termination During Month
         ------------------------
     In the event that the employment of the Executive shall terminate prior to
the end of a calendar month as a result of a termination described in paragraph
1 above, the Company shall pay the Executive, in addition to any other amounts
payable by the Company hereunder, a lump cash sum which shall in no event be
less than the salary plus any bonus to which the Executive would have been
entitled had he remained in full-time employment until the end of the month in
which his employment shall so terminate.
     3.  Post-termination Obligations of Executive; Default by Company
         -------------------------------------------------------------
     All payments and benefits to the Executive under this Agreement after his
full-time employment with the Company shall have terminated shall be subject to
compliance with the following provisions, which compliance shall be subject to
the proviso in subparagraph 3(e) below.  Anything in this paragraph 3 or
elsewhere in this Agreement to the contrary notwithstanding, the Executive may
continue to serve as a director, after his full-time employment with the Company
shall have terminated, of any corporation which he has served as a director for
the last six months of his full-time employment with the Company.
       (a)  Assistance In Litigation
            ------------------------
     The Executive shall, upon reasonable notice, furnish such information and
proper assistance to the Company as may reasonably be required by the Company in
connection with any litigation in which it or any of its subsidiaries or
affiliates is or may become a party.

       (b)  Detrimental Conduct
            -------------------
     The Executive shall not to the material detriment of the Company knowingly
disclose or reveal to any unauthorized person any manufacturing or trade secret
or other confidential information relating to the Company, its subsidiaries or
affiliates, or to any of the businesses operated by them and confirms that such
information constitutes the exclusive property of the Company.  The Executive
shall not otherwise knowingly act or conduct himself to the material detriment
of the Company, its subsidiaries or affiliates, or in a manner which is
materially inimical or contrary to their interests, including, without
limitation, through competition materially detrimental to the Company, its
subsidiaries or affiliates, in any of the businesses in which they may be
engaged at the time of termination of his employment.  The Executive recognizes
that the restrictions on his activities contained in this Agreement are required
for the reasonable protection of the Company and its investments.
       (c)  Discoveries and Inventions
            --------------------------
     If, while employed by the Company or during a period of one year after
termination of such employment, the Executive shall have made, either solely or
jointly with others, any discovery, improvements or invention which would
pertain or relate in any way to the business, products, publications or
processes of the Company, its subsidiaries or affiliates at the time of
termination of his employment, such discovery, improvement or invention (whether
or not of a patentable nature) shall be the exclusive property of the Company.
The Executive shall execute and deliver to the Company without further
compensation any documents which the Company may deem necessary or appropriate
to prepare or prosecute applications for patents upon such discovery,
improvement or invention, to assign and transfer to the Company his entire
right, title and interest in and to such discovery, improvement or invention,
and patents therefor, or otherwise more fully and perfectly to evidence the
Company's ownership thereof.
       (d)  Reimbursement of Expenses
            -------------------------
     The Company shall pay or reimburse the Executive for all reasonable travel
and other expenses incurred by the Executive in performing his obligations under
this paragraph 3.
       (e)  Competition
            -----------
     The Executive shall not engage in competition with any of the businesses in
which the Company, its subsidiaries or affiliates may be engaged at the time of
termination of his employment if such competition should be materially
detrimental to the Company, its subsidiaries or affiliates.
       (f)  Failure to Comply
            -----------------
       If the Executive, for any reason other than death or disability, shall,
without the written consent of the Company, fail to comply with any provision of
this paragraph 3, his rights to any future payments or other benefits hereunder
shall terminate, and the Company's obligations to make such payments and provide
such benefits shall cease; provided, however, that no failure to comply with any
provision of this paragraph 3 shall be deemed to have occurred unless and until
the Executive shall have received written notice on behalf of the Board of
Directors of the Company, specifying the conduct alleged to constitute such
failure, and has thereafter continued to engage in such conduct after a
reasonable opportunity and a reasonable period, but in no event more than sixty
days after receipt of such notice, to refrain from such conduct.  In no event
shall the Executive be under any obligation to repay to the Company any amounts
theretofore paid to him.

<PAGE>
 
       (g)  Post-termination Default in Payments or Benefits
            ------------------------------------------------
     If, after the Executive ceases to be an employee of the Company, the
Company should (i) default in payment of all or any part of the payments
required to be made hereunder or under the Legal Expense Agreement, or (ii) fail
to pay for or provide any benefits required to be provided hereunder, and if the
Company should not remedy such default or failure within thirty (30) days after
having received notice of such default or failure from the Executive, his
spouse, or such other person or entity who or which is entitled thereto, the
applicable payments or benefits set forth in Exhibit B shall, at the sole
                                             ---------                   
election of the Executive, his spouse, or such other person or entity then
entitled thereto, exercised in writing signed by the Executive, his spouse or
such other person or entity, and delivered to the Company within 90 days after
the expiration of such thirty-day period, be accelerated and become immediately
due and payable in a lump sum equal to the total of (x) the severance payment
set forth in Exhibit B, if applicable, and (y) the cost of acquiring insurance
             ---------                                                        
policies which would provide the disability, medical and dental coverages set
forth in Exhibit B, if applicable, and (z) all amounts, if any, payable under
         ---------                                                           
the excess benefit and supplemental retirement plans set forth in Exhibit B in
                                                                  ---------   
an actuarially equivalent lump sum calculated by utilizing the 1983 GAM Table
(or such other pensioner annuity mortality table as the Company with the
Executive's written consent or, following his death, his spouse's or other
Beneficiary's consent, shall determine) and discounted to a present value amount
by applying a discount rate, equal to the arithmetic average of (i.e., one-
twelfth of the sum of) the single employer interest rates for immediate
annuities promulgated by the Pension Benefit Guaranty Corporation each month
during the calendar year immediately preceding the date of payment as set forth
in Appendix B to Part 2619 of 29 Code of Federal Regulations or such successor
to such Appendix B as may be in effect during such calendar year, to all such
retirement payments which otherwise would become due thereafter.  In the event
the election referred to in the preceding sentence has been made, then the total
amount due and payable from the Company pursuant to this subparagraph shall be
the sum of all accelerated amounts, together with any expenses incurred in
enforcing payment thereof (including all reasonable legal fees).  In making the
foregoing retirement payment calculations, the intent is to compute a lump sum
amount which will provide the Executive and his spouse or other Beneficiary, as
the case may be, with the same amount, after deduction of all federal, state and
municipal income taxes, as he and his spouse or other Beneficiary, as the case
may be, would have retained, after all such income taxes, had payments and
benefits been made and provided as originally scheduled and without
acceleration.  It is understood and agreed that this subparagraph 3(g) shall not
apply to any default or failure to pay, as described in the first sentence of
this subparagraph 3(g), which occurs during the Executive's period of
employment; upon any such default or failure to pay, the Executive shall be
entitled to such payments as may be applicable pursuant to subparagraph 1(a).
     4.  Determination of Benefits
         -------------------------
     Whenever under this Agreement it is necessary to determine whether one
benefit is less than, equal to or larger than another, whether or not such
benefits are provided under this Agreement, such determination shall be made by
the Company's independent consulting actuary, using mortality, interest and any
other assumptions normally used at the time by such actuary in determining
actuarial equivalents for the purpose of employee benefit plans of the Company.
     5.  (a)  Time of Payment
              ---------------
     Anything in this Agreement to the contrary notwithstanding, the Company
may, for its

                                       6
<PAGE>
 
own administrative convenience or for any other reason deemed by it sufficient,
accelerate payment to the Executive of any sums due under this Agreement
following termination of his employment; provided, however, that payments by the
Company under this Agreement in any one calendar year shall not, as a result of
such acceleration, together with any payments required to be made under the
pension plan of the Company, exceed an amount equal to (i) 80 percent of his
monthly rate of salary paid for the last full calendar month of his employment,
multiplied by (ii) the number 12.
       (b)  Withholding of Taxes
            --------------------
    The Company may withhold from any benefits payable under this Agreement all
federal, state, city or other taxes as shall be required pursuant to any law or
governmental regulation or ruling.
     6.  Decisions by Company
         --------------------
     Except as otherwise expressly provided in this Agreement, any decision or
action by the Company relating to this Agreement, its operation or its
termination, shall be made by the Board of Directors.  Any decision or action of
such Board shall, to the extent permitted by law, be by the affirmative vote of
not less than three-fourths of the members of the Board of Directors then in
office; provided, however, that in the event of any dispute as to any benefit
payable under this Agreement, the Executive shall have the same rights as a
Participant under the Company's pension plan in effect at the time with respect
to the method of determining such dispute and enforcing his rights with respect
thereto.
     7.  Prior Agreements
         ----------------
     This Agreement shall supersede any prior employment and severance agreement
between the Company or any predecessor of the Company and the Executive, but
this Agreement shall not affect or operate to reduce any benefit or compensation
of any kind not expressly provided for in this Agreement, including, without
limitation, any employee stock option or stock appreciation right and any
agreements under the Company's Restricted Share Performance Plan.
     8.  Consolidation or Merger
         -----------------------
     Nothing in this Agreement shall preclude the Company from consolidating or
merging into or with, or transferring all or substantially all of its assets to,
another corporation which assumes this Agreement and all obligations of the
Company hereunder.  Upon such a consolidation, merger or transfer of assets and
assumption, the term, "Company", shall refer to such other corporation and this
Agreement shall continue in full force and effect.
     9.  (a)  Non-assignability
              -----------------
     Neither this Agreement nor any right or interest hereunder shall be
assignable by the Executive or the beneficiaries of the Executive or by his
legal representatives without the Company's prior written consent; provided,
however, that nothing in this subparagraph 9(a) shall preclude (i) the Executive
from designating a beneficiary to receive any benefit payable on his death, and
(ii) the legal representatives of the estate of the Executive from assigning any
rights hereunder to the person or persons entitled thereto under his will or, in
the case of intestacy, to the person or persons entitled thereto under the laws
of intestacy applicable to his estate.
        (b)  No Attachment
             -------------
     Except as otherwise required by law, no right to receive payments under
this Agreement shall be subject to anticipation, commutation, alienation, sale,
assignment, encumbrances, charge, pledge or hypothecation or to execution,
attachment, levy or similar process or assignment by operation of law, and any
attempt, voluntary or involuntary, to effect any such action shall be null, void
and of no effect.

        (c)  Binding Agreement
             -----------------
     This Agreement shall be binding upon and inure to the benefit of the
Company, its successors and assigns.
        (d)  Unfunded Obligations; Trust Agreement
             -------------------------------------
         (i)  All payments to be made hereunder shall be made from the general
funds of the Company.  To the extent that any person or entity acquires a right
to receive any payment hereunder, such right shall be no greater than the right
of an unsecured general creditor of the Company except to the extent otherwise
provided by law.  No person who is entitled to payments hereunder shall have any
right, title or interest in or to any assets or investments which may be
acquired or made by the Company to aid it in meeting its obligations hereunder.
          (ii)  Anything in this subparagraph 9(d) or elsewhere in this
Agreement to the contrary notwithstanding, the Company may provide the Executive
with collateral security, in the form of a bank letter of credit, an interest in
a trust or otherwise, to secure a portion of any or all of the Company's
obligations to the Executive under this Agreement and any other agreement.  In
this connection, the Company has entered into a Trust Agreement substantially in
the form attached hereto as  Exhibit C and, under the circumstances and upon the
                            ----------                                          
terms and conditions set forth therein, the Executive will be a beneficiary
under the Trust therein established, this Agreement and the Legal Expense
Agreement (and its related memorandum) will be listed on Exhibit I of such Trust
Agreement, the amounts to be deposited with the trustee under the Trust
Agreement shall be those set forth on the Schedule of Amounts to be Deposited in
Trust Upon a Potential Change in Control, a copy of which is attached hereto as
Exhibit D, and any other benefits which the Company, in its sole discretion,
---------                                                                   
shall agree to secure by the Trust Agreement.
         (iii)  If a Potential Change in Control should take place while the
Executive is in the employ of the Company, the value of the benefits set forth
in Exhibit D to be delivered by the Company to the trustee under such Trust
   ---------                                                               
Agreement shall be equal to the total of (x) the severance, options,
contingently credited shares and legal expenses payments set forth in Exhibit D,
                                                                      --------- 
(y) the cost of acquiring insurance policies which would provide the disability,
medical and dental coverages set forth in Exhibit D, and (z) all amounts, if
                                          ---------                         
any, payable under the excess benefit and supplemental retirement plans payments
(as described in subparagraph 1(a)(iv) above) set forth in Exhibit D.
                                                           --------- 
         (iv)  The value of the excess benefit and supplemental retirement plans
payments shall be an actuarially equivalent amount calculated by utilizing the
1983 GAM Table (or such other pensioner annuity mortality table as the Company
with the Executive's written consent, or following his death, his spouse's or
other Beneficiary's consent, shall determine) and discounted to a present value
amount by applying a discount rate, equal to the arithmetic average of (i.e.,
one-twelfth of the sum of) the single employer interest rates for immediate
annuities promulgated by the Pension Benefit Guaranty Corporation each month
during the calendar year immediately preceding the date of payment as set forth
in Appendix B to Part 2619 of 29 Code of Federal Regulations or such successor
to such Appendix B as may be in effect during such calendar year, to all such
retirement benefits which otherwise would become due thereafter.  In making the
foregoing retirement payment calculations, the intent is to compute a lump sum
payment which will provide the Executive  with the same amount of benefit, after
deduction of all federal, state and municipal income taxes, as he would have
retained, after all such income taxes, had payments been made as originally
scheduled and without acceleration.
         (v)  Anything in this subparagraph 9(d) or elsewhere in this Agreement
to the

                                       8
<PAGE>
 
contrary notwithstanding, the amount to be paid by the Company to the trustee
pursuant to the preceding provisions of this subparagraph 9(d) shall be reduced
by the amount, if any, that the Board of Directors of the Company expressly
determines, in its sole discretion on the advice of the Company's independent
public accountants or its tax counsel or other experts selected by the Board of
Directors, as a result of the application of the provisions of paragraph 14
below, is not expected to be paid by the trustee to the Executive and his
beneficiary or beneficiaries.
         (vi)  The Company shall continue to be liable to make all payments and
provide all benefits required to be made and provided hereunder to the extent
such payments have not been made or such benefits have not been provided through
the above-mentioned trust.
         (vii)  For purposes of this Agreement, a "Potential Change in Control"
shall be deemed to have occurred if
              (A)  the Company enters into an agreement, the consummation of
           which would result in the occurrence of a Change in Control of the
           Company;
              (B)  any person (including the Company) publicly announces an
           intention to take or to consider taking actions which if consummated
           would constitute a Change in Control of the Company;
              (C)  any person, other than a trustee or other fiduciary holding
           securities under an employee benefit plan of the Company, is or
           becomes the beneficial owner, directly or indirectly, of securities
           of the Company representing ten percent (10%) or more of the combined
           voting power of the Company's then outstanding securities; or
              (D)  the Board of Directors adopts a resolution to the effect
           that, for purposes of this Agreement, a Potential Change in Control
           of the Company has occurred.
     10.   (a)  Amendment of Agreement
                ----------------------
     No amendment or modification of this Agreement shall be deemed effective
unless and until executed in writing.
           (b)  No Waiver
                ---------
     No term or condition of this Agreement shall be deemed to have been waived,
nor shall there be any estoppel to enforce any provision of this Agreement,
except by written instrument of the party charged with such waiver or estoppel.
Any written waiver shall not be deemed a continuing waiver unless specifically
stated, shall operate only as to the specific term or condition waived and shall
not constitute a waiver of such term or condition for the future or as to any
act other than that specifically waived.
     11.  Severability
          ------------
     If for any reason any provision of this Agreement shall be held invalid,
such invalidity shall not affect any other provision of this Agreement not held
so invalid, and all other such provisions shall to the full extent consistent
with law continue in full force and effect.  If any such provision shall be held
invalid in part, such invalidity shall in no way affect the rest of such
provision not held so invalid, and the rest of such provision, together with all
other provisions of this Agreement, shall likewise to the full extent consistent
with law continue in full force and effect.
     12.  Headings
          --------
     The headings of paragraphs are included solely for convenience of reference
and shall not control the meaning or interpretation of any of the provisions of
this Agreement.
     13.  Governing Law
          -------------
     The validity, interpretation, construction, performance and enforcement of
this Agreement shall be governed by the laws of the State of New York without

     14.  Parachute Tax
          -------------
     If the payments and benefits provided for the Executive under this
Agreement, together with any other payments and benefits that the Executive may
have a right to receive from the Company or any other person or entity, would
result in "excess parachute payments" (as defined in Section 280G of the Code),
the payments and benefits to be made and provided to the Executive and his
beneficiary or beneficiaries pursuant to this Agreement shall be reduced to the
largest whole-dollar amount that will result in there being no such "excess
parachute payment."  The existence or absence of any such "excess parachute
payment," the amount of any such reduction, and the item or items to be reduced,
if any, shall be determined, in each case, by the Executive or, following his
death, his beneficiary or beneficiaries, and the specifics of such determination
shall be delivered in writing to the Company and to the trustee of the Trust
referred to in subparagraph 9(d)(ii) above, at the time of the Executive's
termination within three years after a Change in Control, or as soon as
practicable thereafter, by the Executive or, following his death, his
beneficiary or beneficiaries.  The reasonable fees and expenses of such tax
counsel and financial advisor as may reasonably be called upon to assist the
Executive or his beneficiary or beneficiaries in the foregoing endeavors shall
be paid by the Company.

     15.  Notices
          -------

     16.  Arbitration
          -----------
     Any dispute between the Executive and the Company as to the interpretation
or application of any of the provisions of this Agreement may, at the

                            FORM OF TRUST AGREEMENT
                            -----------------------

         TRUST AGREEMENT (the "Trust"), dated as of February 19, 1987, by and
between Champion International Corporation, a New York corporation (the
"Company"), and Connecticut National Bank (the "Trustee").
         WHEREAS, the Company is obligated under the individual agreements set
forth on Exhibit I (together with any additional agreements included on Exhibit
I pursuant to Section 2.01(c) hereof, the "Agreements") to make specified
payments to certain of the Company's executives (together with any additional
executives and retired executives included on Exhibit I pursuant to Section
2.01(c) hereof, the "Executives"); and
         WHEREAS, the aforesaid obligations of the Company are not funded or
otherwise secured, and the Company has agreed, to the extent practicable, to
assure that the future payment of certain of said obligations will not be
improperly withheld in the event that a "Change in Control" (as defined herein)
of the Company should occur; and
         WHEREAS, for purposes of assuring that such payments will not be
improperly withheld, the Company desires to deposit with the Trustee, subject
only to the claims of the Company's existing or future general creditors in the
event of bankruptcy or insolvency (as hereinafter provided), amounts of cash or
marketable securities sufficient to fund such payments;
          NOW, THEREFORE, in consideration of the mutual agreements contained
herein and for other good and valuable consideration, the parties hereto agree
as follows:
                                   ARTICLE I
                                 THE AGREEMENTS
                                 --------------
            SECTION 1.01  Agreements.  The agreements subject to this Trust
            ------------------------                                       
consist of the Agreements listed from time to time on Exhibit I hereof
respectively.  The Company shall continue to be liable to the Executives to make
all payments required under the terms of such Agreements to the extent such
payments have not been made pursuant to this Trust.

                                   ARTICLE II
                           TRUST AND THE TRUST CORPUS
                           --------------------------
          SECTION 2.01  Trust.
                        ----- 
          (a)  The Company will deliver to the Trustee to be held in trust
hereunder, concurrently with the execution of this Trust, the sum of $100 in
cash, and upon the occurrence of a "Potential Change in Control" (as defined in
Section 3.02), (i) an additional amount in cash (or in marketable securities
having a fair market value equal to such amount, or some combination thereof)
representing the sum of the amounts, determined as provided in Section 4.02,
which is estimated to be sufficient to fund the Company's obligations to pay to
the Executives certain amounts and benefits due to them pursuant to the
Agreements and (ii) an amount estimated by the Trustee to be sufficient to pay
all of the Trustee's fees and expenses hereunder with respect to the period of
time that this Trust Agreement shall be in effect.
          (b)  The payment by the Company pursuant to Section 2.01(a)(i) hereof
shall be accompanied by a Payment Schedule for each Executive as required by
Section 4.02(a) hereof.
          (c)  The Company may, subject to the provisions of Section 2.01(d),
from time to time prior to the occurrence of a Change in Control revise Exhibit
I in order to include thereon (A) additional Executives, and (B) additional
Agreements

                                       1
<PAGE>
 
with respect to any Executive.  If a revised Exhibit I is delivered to the
Trustee with respect to any Executive upon or after the occurrence of a
Potential Change in Control, the Company will deliver to the Trustee,
concurrently with such revised Exhibit I:
          (x)  a Payment Schedule or a revised Payment Schedule, as applicable,
               with respect to such Executive which complies with Section
               4.02(a) and which sets forth the additional amount delivered to
               the Trustee with respect to such Executive, and
          (y)  an amount which is estimated to be sufficient when added to the
               amount or amounts previously delivered to the Trustee to fund the
               Company's obligations under the Payment Schedule or the revised
               Payment Schedule, as applicable, pursuant to such Executive's
               Agreements.
Such Payment Schedule or revised Payment Schedule shall be effective in
accordance with the provisions of Section 4.02(b). A revised Exhibit I shall be
effective upon the later of (C) receipt by Trustee of such revised Exhibit I and
(D) receipt by the Trustee of all amounts required under this Section 2.01(c),
if any, and such revised Exhibit I shall supersede any and all such Exhibits
previously delivered to the Trustee.
          (d)  In no event may Exhibit I be revised to eliminate any Executive
or any Agreements with respect to any Executive without such Executive's written
consent, except as provided in the following sentence.  Prior to the occurrence
of a Change in Control, the Company shall deliver instructions to the Trustee to
delete the name of, and the Agreements with respect to, an Executive from
Exhibit I promptly following the termination of his employment with the Company
prior to the occurrence of a Change in Control.  The Trustee shall make such
deletions and shall be able to rely upon such instructions and shall have no
duty to inquire with respect to the termination of such Executive's employment
with the Company.  The deletions described in the immediately preceding sentence
may not be made with respect to instructions delivered to the Trustee on or
after the occurrence of a Change in Control of the Company.  Notwithstanding the
foregoing, following a Potential Change in Control the Company may, in its
discretion, add retired Executives and their agreements with the Company to
Exhibit I in accordance with Section 2.01(c) to assure that the payment of
certain amounts payable by the Company to such retired Executives under such
agreements will not be improperly withheld following a Change in Control.
           SECTION 2.02  Trust Corpus.
                         ------------ 
          (a) As used herein, the term "Trust Corpus" shall mean the amounts
delivered to the Trustee as described in Section 2.01 and 4.02(b) hereof in
whatever form held or invested as provided herein.  The Trust Corpus shall be
held, invested and reinvested by the Trustee in cash or marketable securities
only in accordance with this Section 2.02. The Trustee shall use its good faith
efforts to invest or reinvest from time to time all or such part of the Trust
Corpus as it believes prudent under the circumstances in either one or a
combination of the following investments:
                         (i)  investments in direct obligations of the United
                 States of America or agencies of the United States of America
                 or obligations unconditionally and fully guaranteed as to
                 principal and interest by the United States of America, in each
                 case maturing within one year or less from the date of
                 acquisition; or
 
                                       2
<PAGE>
 
                      (ii)  investments in negotiable certificates of deposit
              (in each case maturing within one (1) year or less from the date
              of acquisition) issued by a commercial bank organized and existing
              under the laws of the United States of America or any state
              thereof having a combined capital and surplus of at least
              $1,000,000,000, including the Trustee's banking department;
              provided, however, that the Trustee shall not be liable for any
              --------  -------
              failure to maximize the income earned on that portion of the Trust
              Corpus as is from time to time invested or reinvested as set forth
              above, nor for any loss of income due to liquidation of any
              investment which the Trustee, in its sole discretion, believes
              necessary to make payments or to reimburse expenses under the
              terms of this Trust.

          (b)  The Trust is intended to be grantor trust within the meaning of
Section 671 of the Internal Revenue Code of 1986, as amended (the "Code"),
except as hereinafter provided, all interest and other income earned on the
investment of the Trust Corpus shall be the property of the Company and shall
not constitute a part of the Trust Corpus.  Except as provided in Section
4.02(a), the interest and other income earned in any calendar quarter shall be
paid over to the Company by the Trustee as promptly as practicable after the end
of such calendar quarter.
          (c)  All losses of principal in respect of, and expenses (including,
as provided in Section 5.01(g) hereof, any expenses of the Trustee) charged
against, the Trust Corpus shall be for the account of the Company and the
Company shall be obligated to promptly reimburse the Trust Corpus for any loss
in principal amount of, or expense charged against, the Trust Corpus except to
the extent that such amounts have been applied to reduce amounts payable to the
Company pursuant to Section 2.02(b) hereof.  To the extent any such losses and
expenses are not reimbursed by the Company, the aggregate amount payable to an
Executive under the applicable Payment Schedule shall be reduced by a portion of
such losses and expenses, as determined on a pro rata basis.
                                  ARTICLE III
                               CHANGE IN CONTROL

         SECTION 3.02  Definition of a Potential Change in Control.  For
                       -------------------------------------------      
purposes of this Trust, a Potential Change in Control shall be deemed to have
occurred if
          (a)  the Company enters into an agreement, the consummation of which
would result in the occurrence of a Change in Control of the Company;
          (b)  any person (including the Company) publicly announces an

constitute a Change in Control of the Company;
          (c)  any person, other than a trustee or other fiduciary holding

          SECTION 3.03  Notification of the Trustee.  The Company shall notify
                        ---------------------------                           
the Trustee of the occurrence of a Potential Change in Control and the Company
shall or an Executive may notify the Trustee of the occurrence of a Change in
Control, and the Trustee may rely on such notice or on any other actual notice,

independent determination as to the occurrence of a Potential Change in Control
or Change in Control.

                          RELEASE OF THE TRUST CORPUS
                          ---------------------------
            The Trustee shall hold the Trust Corpus in its possession under the
provisions of this Trust Agreement until authorized to deliver the Trust Corpus
or any specified portion thereof as follows:
          SECTION 4.01  Delivery to the Company.
                        ----------------------- 
          (a)  Any amount in excess of $100 delivered to the Trustee pursuant to
Section 2.01 hereof or otherwise constituting part of the Trust Corpus shall be
returned to the Company, unless within six (6) months of such delivery to the
Trustee a Change in Control shall have occurred.  Such six month period shall be
renewed (i) for any Potential Change in Control which occurs during any initial
six month period or (ii) by a resolution adopted by the Board of Directors and
delivered to the Trustee by the Company to the effect that such an initial six
month period (or a six month period that is renewed in accordance with clause
(i) of this Section 4.01(a)) shall start anew.
          (b)  Any amount held by the Trustee for the benefit of an Executive
shall be paid to the Company immediately following the final payment of all
amounts payable to such Executive pursuant to the terms of the Executive's
Agreement, as certified to the Trustee by the Executive.
          (c)  Upon the termination of the Trust as provided in the first
sentence of Section 6.01(a), the Trustee shall pay to the Company the amount of
the Trust Corpus, less all payments, expenses, taxes and other charges under
this Trust Agreement as of such date of termination, provided that in the event
that the Trust shall continue with respect to one or more Executives in
accordance with the provisions of Section 6.01(b), the Trustee shall pay to the
Company the amount that would have been payable to the Company if the Trust had
terminated as provided in Section 6.01(a), less (i) the amounts subject to
litigation or arbitration for each such Executive, as certified to the Trustee
by each such Executive, and (ii) an amount

                                       4
<PAGE>
 
estimated by the Trustee to be sufficient to pay all of the Trustee's fees and
expenses with respect to the additional period of time that the Trust shall
continue in effect pursuant to Section 6.01(b).
           SECTION 4.02  Deliveries to Executives.
                         ------------------------ 
          (a)  The Company shall deliver to the Trustee, upon the occurrence of
a Potential Change in Control, a separate schedule for each Executive (the
"Payment Schedule') indicating (x) the amounts delivered to the Trustee for the
benefit of each such Executive pursuant to Section 2.01(a)(i) in accordance with
such Executive's Agreements and (y) the amounts payable in respect of such
Executive, or providing a formula or instructions acceptable to the Trustee for
determining the amounts so payable.  The Payment Schedule shall include
instructions as to the amount of interest, if any, accruing in respect of an
Executive and such instructions may be revised from time to time prior to the
occurrence of a Change in Control.  Each Payment Schedule also shall be
delivered by the Company to such Executive.  The aggregate payment to be made
hereunder to an Executive by the Trustee shall not exceed the aggregate amount
delivered to the Trustee for the benefit of such Executive as indicated in the
Payment Schedule applicable to such Executive.  The Trustee shall make payments
to each Executive under the Payment Schedule applicable to such Executive upon
receipt by the Trustee of a written request for payment signed by the Executive
or, following his death, his beneficiary or beneficiaries.  Such request shall
set forth each of the following items: (i) the specific amount of payment
requested, (ii) the specific Agreement or Agreements and the specific section or
sections of such Agreements under which such payment is to be made, (iii) the
existence or absence of any "excess parachute payment"  (as defined in Section
280G of the Code) respecting the amount payable to such Executive in accordance
with the applicable Payment Schedule and (iv) the amount of any reduction in the
amount otherwise payable to such Executive in accordance with the applicable
Payment Schedule and the item or items to be reduced, if any.  The Trustee shall
rely upon such written request in making payments under the Payment Schedule and
shall have no duty to inquire into the amounts, instructions or formulas set
forth in the Payment Schedule or the Executive's right to such payments.
          (b)  The Company may from time to time after the occurrence of a
Potential Change in Control deliver concurrently to the Trustee (i) a revised
Payment Schedule with respect to any Executive which sets forth the aggregate
amounts payable with respect to such Executive and (ii) an amount which is
estimated to be sufficient when added to the amount or amounts previously
delivered to the Trustee to fund the Company's obligations pursuant to such
Executive's Agreements.  A revised Payment Schedule shall be effective upon the
later of (x) receipt by the Trustee of such revised Payment Schedule and (y)
receipt by the Trustee of all amounts required under Section 4.02(b)(ii) and
such revised Payment Schedule shall supersede any and all Payment Schedules
previously delivered by the Company to the Trustee with respect to such
Executive.
          (c)  Except as provided in this Section 4.02(c), a revised Payment
Schedule may not reduce the amounts payable with respect to an Executive
pursuant to the prior Payment Schedule for such Executive except with the
written consent of such Executive.
     (i)  After a Potential Change in Control and before a Change in Control,
     the Company shall deliver to the Trustee, promptly following the
     termination of an Executive's employment with the Company, a revised
     Payment Schedule with respect to such Executive which deletes all of the
     amounts set forth on the prior Payment Schedule for such Executive.  The
     Trustee may rely


                                       5
<PAGE>
 
     upon such revised Payment Schedule and shall have no duty to inquire with
     respect to the termination of such Executive's employment with the Company.
     The Trustee shall return to the Company all amounts previously delivered by
     the Company to the Trustee for the benefit of such Executive.
     Notwithstanding the foregoing, following a Potential Change in Control the
     Company may, in its discretion, deliver Payment Schedules for retired
     Executives in accordance with Section 4.02(a) hereof.
     (ii)  After a Potential Change in Control and before a Change in Control,
     the Company may deliver a revised Payment Schedule with respect to an
     Executive which reduces the amounts payable in respect of such Executive
     pursuant to his prior Payment Schedule as the result of a more accurate
     calculation by the Company of the amount of the benefits to which such
     Executive is entitled pursuant to his Agreements.  The Trustee may rely on
     such revised Payment Schedule and shall have no duty to inquire with
     respect to said calculation.  The Trustee shall return to the Company an
     amount equal to such reduction.
A revised Payment Schedule of the type described in this Section 4.02(c) may not
be delivered to, or honored by, the Trustee on or after the occurrence of a
Change in Control of the Company.  A revised Payment Schedule shall be effective
upon its receipt by the Trustee and shall supersede any and all Payment
Schedules previously delivered by the Company to the Trustee with respect to
such Executive.
          (d)  The Trustee shall be permitted to withhold from any payment due
to an Executive hereunder the amount required by law to be so withheld under
federal, state and local withholding requirements or otherwise, and shall pay
over to the appropriate government authority the amounts so withheld.  The
Trustee may rely on instructions from the Company as to any required withholding
and shall be fully protected under Section 5.01(g) hereof in relying on such
instructions.
          (e)  Except as otherwise provided herein, in the event of any final
determination by the Internal Revenue Service or a court of competent
jurisdiction, which determination is not appealable or the time for appeal or
protest of which has expired, or the receipt by the Trustee of a substantially
unqualified opinion of tax counsel selected by the Trustee with the written
consent of the Company, which determination determines, or which opinion
concludes, that the Executives or any particular Executive, is subject to
federal income taxation on amounts held in Trust hereunder prior to the
distribution to the Executives or Executive of such amounts, the Trustee shall,
on receipt by the Trustee of such opinion or notice of such determination, pay
to each Executive the portion of the Trust Corpus includible in such Executive's
federal gross income.
          SECTION 4.03  Deliveries to Creditors of the Company.  It is the
                        --------------------------------------            
intent of the parties hereto that the Trust Corpus is and shall remain at all
times subject to the claims of the general creditors of the Company in the event
of bankruptcy or insolvency as hereinafter provided, but in no other event.
Accordingly, the Company shall not create a security interest in the Trust
Corpus in favor of the Executives or any creditor.  If the Trustee receives the
notice provided for in Section 4.04 hereof, or otherwise receives actual notice
that the Company is insolvent or bankrupt as defined in Section 4.04 hereof, the
Trustee will make no further distributions of the Trust Corpus to any of the
Executives but will deliver the entire amount of the Trust Corpus only as a
court of competent jurisdiction, or duly appointed receiver or other person
authorized to act by such a court, may direct to make the Trust Corpus available
to satisfy the claims of the Company's general creditors.  The Trustee shall
resume

                                       6
<PAGE>
 
holding the Trust Corpus under the terms hereof and resume any distribution of
Trust Corpus to the Executives under the terms hereof, upon no less than thirty
(30) days advance notice to the Company, if it determines that the Company was
not, or is no longer, bankrupt or insolvent.  Unless the Trustee has actual
knowledge of the Company's bankruptcy or insolvency, the Trustee shall have no
duty to inquire whether the Company is bankrupt or insolvent.
          SECTION 4.04  Notification of Bankruptcy or Insolvency.  The Company,
                        ----------------------------------------               
through its Board of Directors and Chief Executive Officer, shall advise the
Trustee promptly in writing of the Company's bankruptcy or insolvency.  The
Company shall be deemed to be bankrupt or insolvent in the following
circumstances:
          (a)  The Company is subject to a pending proceeding as a debtor under
 the Bankruptcy Reform Act of 1978, as amended; or
          (b)  The Company shall generally not pay its debts as such debts
 become due or shall cease to pay its debts in the ordinary course of business.

                                    TRUSTEE
                                    -------
          SECTION 5.01  Trustee.
                        ------- 
           (a)  The duties and responsibilities of the Trustee shall be limited
 to those expressly set forth in this Trust, and no implied covenants or
 obligations shall be read into this Trust against the Trustee.
          (b)  If all or any part of the Trust Corpus is at any time attached,
garnished, or levied upon by any court order, or in case the payment,
assignment, transfer, conveyance or delivery of any such property shall be
stayed or enjoined by any court order, or in case any order, judgment or decree
shall be made or entered by a court affecting such property or any part thereof,
then and in any of such events the Trustee is authorized, in its sole
discretion, to rely upon and comply with any such order, judgment or decree, and
it shall not be liable to the Company or any Executive by reason of such
compliance even though such order, judgment or decree subsequently may be
reversed, modified, annulled, set aside or vacated.
          (c)  The Trustee shall maintain such books, records and accounts as
may be necessary for the proper administration of the Trust Corpus, including,
without limitation, as provided in Article II hereof, and shall render to the
Company, on or prior to each January 31 following the date of this Trust until
the termination of this Trust (and on the date of such termination), an
accounting with respect to the Trust Corpus as of the end of the then most
recent calendar year (and as of the date of such termination).  The Trustee will
at all times maintain a separate bookkeeping account for each Executive to which
it will credit each amount delivered by the Company to the Trustee with respect
to such Executive.  Upon the written request of an Executive or the Company, the
Trustee shall deliver to such Executive or the Company, as the case may be, a
written report setting forth the amount held in the Trust for such Executive (or
each Executive if such request is made by the Company) and a record of the
deposits made with respect thereto by the Company.  Unless the Company or any
Executive shall have filed with the Trustee written exceptions or objections to
any such statement and account within one hundred eighty (180) days after
receipt thereof, the Company or the Executive shall be deemed to have approved
such statement and account, and in such case the Trustee shall be forever
released and discharged with respect to all matters and things reported in such
statement and account as though it had been settled by a decree of a court of
competent jurisdiction in an action or proceeding to which the Company and the
Executive were parties.
          (d)  The Trustee shall not be liable for any act taken or omitted to
be taken hereunder if taken or omitted to be taken by it in good faith, absent
the gross

                                       7
<PAGE>
 
negligence or wilful misconduct of the Trustee.  The Trustee shall also be fully
protected in relying upon any notice given hereunder which it in good faith
believes to be genuine and executed and delivered in accordance with this Trust.
          (e)  The Trustee may consult with legal counsel to be selected by it,
and the Trustee shall not be liable for any action taken or suffered by it in
accordance with the advice of such counsel.
          (f)  The Trustee shall be reimbursed by the Company for its reasonable
expenses incurred in connection with the performance of its duties hereunder and
shall be paid reasonable fees for the performance of such duties in the manner
provided by paragraph (g) of this Section 5.01.
          (g)  The Company agrees to indemnify and hold harmless the Trustee
from and against any and all damages, losses, claims or expenses as incurred
(including expenses of investigation and fees and disbursements of counsel to
the Trustee and any taxes imposed on the Trust Corpus or income of the Trust)
arising out of or in connection with the performance by the Trustee of its
duties hereunder, other than such damages, losses, claims or expenses arising
out of the Trustee's gross negligence or wilful misconduct.  Any amount payable
to the Trustee under paragraph (f) of this Section 5.01 or this paragraph (g)
shall be paid by the Company promptly upon demand therefor by the Trustee or, in
the event that the Company fails to make such payment, from the Trust Corpus.
In the event that payment is made hereunder to the Trustee from the Trust
Corpus, the Trustee shall promptly notify the Company in writing of the amount
of such payment.  The Company agrees that, upon receipt of such notice, it will
deliver to the Trustee to be held in the Trust an amount in cash (or in
marketable securities or in some combination thereof) equal to any payments made
from the Trust Corpus to the Trustee pursuant to paragraph (f) of this Section
5.01 or this paragraph (g).  The failure of the Company to transfer any such
amount shall not in any way impair the Trustee's right to indemnification,
reimbursement and payment pursuant to paragraph (f) of this Section 5.01 or this
paragraph (g).
          SECTION 5.02  Successor Trustee.  The Trustee may resign and be
                        -----------------                                
 discharged from its duties hereunder at any time by giving notice in writing of
 such resignation to the Company and each Executive specifying a date (not less
 than thirty (30) days after the giving of such notice) when such resignation
 shall take effect.  Promptly after such notice, the Company (or, if a Change in
 Control shall previously have occurred, Executive(s) having at least 65%
 percent of all amounts then held in the Trust credited to their accounts shall
 appoint a successor trustee, such trustee to become Trustee hereunder upon the
 resignation date specified in such notice.  If the Company fails to appoint a
 successor trustee or if such Executive(s) are unable to so agree upon a
 successor trustee within thirty (30) days after such notice, the Trustee shall
 be entitled, at the expense of the Company, to petition a United States
 District Court or any of the courts of the State of New York having
 jurisdiction to appoint its successor.  The Trustee shall continue to serve
 until its successor accepts the trust and receives delivery of the Trust
 Corpus.  The Company (or, if a Change in Control shall previously have
 occurred, Executive(s) having at least 65% percent of all amounts then held in
 the Trust credited to their accounts) may at any time substitute a new trustee
 by giving fifteen (15) days notice thereof to the Trustee then acting.  In the
 event of such removal or resignation, the Trustee shall duly file with the
 Company and, on and after a Change in Control, the Executives a written
 statement or statements of accounts and proceedings as provided in Section
 5.01(c) hereof for the period since the last previous annual accounting of the
 Trust, and if written objection to such account is not filed as provided in
 Section 5.01(c) hereof, the Trustee shall to the maximum extent

                                       8
<PAGE>
 
permitted by applicable law be forever released and discharged from all
liability and accountability with respect to the propriety of its acts and
transactions shown in such account.  The Trustee and any successor thereto
appointed hereunder shall be a commercial bank which is not an affiliate of the
Company, but which is a national banking association or established under the
laws of one of the states of the United States, and which has equity in excess
of $100 million.
          SECTION 5.03  Settlement of Accounts.  Notwithstanding any other
                        ----------------------                            
 provision of this Agreement, in the event of the termination of the Trust, or
 the resignation or discharge of the Trustee, the Trustee shall have the right
 to a settlement of its accounts, which accounting may be made, at the option of
 the Trustee, either (a) by a judicial settlement in a court of competent
 jurisdiction; or (b) by agreement of settlement, release and indemnity from the
 Company to the Trustee.
                                   ARTICLE VI
                       TERMINATION, AMENDMENT AND WAIVER
                       ---------------------------------
              SECTION 6.01  Termination.
              ------------------------- 
          (a)  Except as provided in Section 6.01(b) of this Agreement, this
Trust shall terminate forty-two months after the occurrence of a Change in
Control, or, if earlier, upon the earliest of either of the following events:
(i) the exhaustion of the Trust Corpus; or (ii)  the final payment of all
amounts payable to all of the Executives pursuant to the Agreements, as
certified to the Trustee by each Executive.  Promptly upon termination of this
Trust, any remaining portion of the Trust Corpus, less all payments, expenses,
taxes and other charges under this Trust Agreement as of such date of
termination, shall be paid to the Company.
           (b)  Notwithstanding any other provision of this Agreement, in the
 situation where the payments under an Executive's Agreements are the subject of
 litigation or arbitration, and if the Trust Corpus has not been exhausted with
 respect to such Executive, the Trust shall not terminate and the funds held in
 the Trust with respect to such Executive shall continue to be held by the
 Trustee until the final resolution of such litigation or arbitration.  The
 Trustee may assume that no Agreement of an Executive is the subject of such
 litigation or arbitration unless the Trustee receives written notice from an
 Executive or the Company with respect to such litigation or arbitration.  The
 Trustee may rely upon written notice from an Executive as to the final
 resolution of such litigation or arbitration.  Following such final resolution,
 the Trust shall terminate with respect to each Executive described in this
 Section 6.01(b) upon the earliest of either of the following events: (i) the
 exhaustion of the Trust Corpus held by the Trustee with respect to such
 Executive; or (ii) the final payment of all amounts payable to the Executive
 pursuant to such Executive's Agreements, as certified to the Trustee by such
 Executive.  Promptly upon termination of this Trust with respect to an
 Executive described in Section 6.01(b), any remaining portion of the Trust
 Corpus held by the Trustee with respect to such Executive shall be paid to the
 Company.  At such time as the Trust shall be terminated with respect to all
 such Executives, the Trust Corpus, less all payments, expenses, taxes and other
 charges attributable to the extension of the Trust term beyond the termination
 date described in Section 6.01(a), shall be paid promptly to the Company.
          SECTION 6.02  Amendment and Waiver.  Except as provided in Sections
                        --------------------                                 
2.01(c),(d) and 4.02(b),(c), this Trust may not be amended except by an
instrument in writing signed on behalf of the parties hereto together with the
written consent of Executives having at least 65% of all amounts then held in
the Trust credited to their accounts.  The parties hereto, together with the
consent of Executives having at least 65% of all amounts then held in the Trust
credited to their accounts,

                                       9
<PAGE>
 
may at any time waive compliance with any of the agreements or conditions
contained herein. Any agreement on the part of a party hereto or an Executive to
any such waiver shall be valid if set forth in an instrument in writing signed
on behalf of such party or Executive. This Trust may not be amended nor may
compliance with any provisions hereunder be waived except by an instrument in
writing signed on behalf of the parties hereto and by at least seventy-five
percent (75%) of the Executives in the situation where, prior to such amendment
or waiver, no payment has been made by the Company pursuant to Section
2.01(a)(i) that is then held by the Trustee. Notwithstanding the foregoing, any
such amendment or waiver may be made prior to a Change in Control by written
agreement of the parties hereto without obtaining the consent of the Executives
if such amendment or waiver does not adversely affect the rights of the
Executives hereunder. Except as provided in Sections 2.01(c),(d) and
4.02(b),(c), no amendment or waiver relating to this Trust may be made (i) with
respect to the amount of funds to be delivered by the Company to the Trustee
with respect to an Executive or by the Trustee to such Executive, or the timing
of such deliveries or (ii) which amends Section 6.01, unless such Executive, in
the case of clause (i) or, all Executives in the case of clause (ii), agree in
writing to such amendment or waiver.
                                  ARTICLE VII
                               GENERAL PROVISIONS
                               ------------------
          SECTION 7.01  Further Assurances.  The Company shall, at any time and
                        ------------------                                     
from time to time, upon the reasonable request of the Trustee, execute and
deliver such further instruments and do such further acts as may be necessary or
proper to effectuate the purposes of this Trust.
          SECTION 7.02  Certain Provisions Relating to this Trust.   (a) This
                        -----------------------------------------            
Trust sets forth the entire understanding of the parties with respect to the
subject matter hereof and supersedes any and all prior agreements, arrangements
and understandings relating thereto.  This Trust shall be binding upon and inure
to the benefit of the parties and their respective successors and legal
representatives.
          (b)  If by the end of the eight-month period following the date
hereof, or such later date as the Company and the Trustee shall agree, counsel
is unable to deliver to the Company a favorable opinion that is satisfactory to
the Company, substantially to the effect that
     (i) the Company will be treated as the owner of the Trust under Section 677
     of the Code and Section 1.677(a)-1(d) of the regulations.  Under Section
     671, the Company must include all of the income, deductions and credits
     against tax of the Trust in computing its own taxable income and credits,
     and
     (ii)   the transfer of assets to the Trust will not constitute a transfer
     of property for purposes of Section 83 of the Code or Section 1.83-3(e) of
     the regulations, and
     (iii)  under Section 451 of the Code, amounts will be includible in the
     gross income of the Executives only in the taxable year or years in which
     such amounts are actually distributed or made available by the Trustee,
the Trust shall immediately terminate and the amount of the Trust Corpus, less
all payments, expenses, taxes and other charges under this Trust Agreement, if
any, as of such date, shall be returned to the Company as soon as possible.
Upon termination of the Trust, the Executives shall have no rights under this
Trust Agreement.
          (c)  This Trust shall be governed by and construed in accordance with
the laws of the State of New York, other than and without reference to any

                                       10
<PAGE>
 
provisions of such laws regarding choice of laws or conflict of laws.
          (d)  In the event that any provision of this Trust or the application
thereof to any person or circumstances shall be determined by a court of proper
jurisdiction to be invalid or unenforceable to any extent, the remainder of this
Trust, or the application of such provision to persons or circumstances other
than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each provision of this Trust shall be valid and enforced
to the fullest extent permitted by law.
          (e)  The article and section headings contained in this Agreement are
solely for the purpose of reference, are not part of the agreement of the
parties and shall not in any way affect the meaning or interpretation of this
Agreement.
          SECTION 7.03   Alienation.  The right of any Trust Beneficiary (as
                         ----------                                         
hereinafter defined) to any benefit or to any payment hereunder shall not be
subject to alienation or assignment.
          SECTION 7.04   Arbitration.  Any dispute between the Executives and
                         -----------                                         
the Company or the Trustee as to the interpretation or application of the
provisions of this Trust and amounts payable hereunder may, at the election of
any party to such dispute (or, if more than one (1) Executive is such a party,
at the election of seventy-five percent (75%) of such Executives), be determined
by binding arbitration within the greater New York City metropolitan area or the
State of Connecticut in accordance with the rules of the American Arbitration
Association then in effect.  Judgment may be entered on the arbitrator's award
in any court of competent jurisdiction.  All fees and expenses of such
arbitration shall be paid by the Trustee and considered an expense of the Trust
under Section 5.01(g).
          SECTION 7.05  Notices.  Any notice, report, demand or waiver required
                        -------
