                AMENDED AND RESTATED CHANGE IN CONTROL AGREEMENT
                ------------------------------------------------


     THIS AMENDED AND RESTATED CHANGE IN CONTROL AGREEMENT ("Agreement") is
entered into effective as of April 9, 2001, by and between VARIAN, INC., a
Delaware corporation (the "Company")/1/, and Garry W. Rogerson, an employee of
the Company ("Employee").



     The Company's Board of Directors (the "Board") has determined that it is in
the best interest of the Company and its stockholders for the Company to agree
to pay Employee termination compensation in the event Employee should leave the
employ of the Company under the circumstances described below.  The Board
recognizes that the possibility of a proposal from a third person, whether or
not solicited by the Company, concerning a possible "Change in Control" of the
Company (as such language is defined in Section 3(d)) will be unsettling to
Employee.  Therefore, the arrangements set forth in this Agreement are being
made to help assure a continuing dedication by Employee to Employee's duties to
the Company notwithstanding the proposal or occurrence of a Change in Control.
The Board believes it imperative, should the Company receive any proposal from a
third party, that Employee, without being influenced by the uncertainties of
Employee's own situation, be able to assess and advise the Board whether such
proposals are in the best interest of the Company and its stockholders, and to
enable Employee to take action regarding such proposals as the Board might
determine to be appropriate.  The Board also wishes to demonstrate to key
personnel that the Company desires to enhance management relations and its
ability to retain and, if needed, to attract new management, and intends to
ensure that loyal and dedicated management personnel are treated fairly.

     In view of the foregoing, the Company and Employee agree as follows:

1.   EFFECTIVE DATE AND TERM OF AGREEMENT.
     ------------------------------------

     This Agreement is effective and binding on the Company and Employee as of
the date hereof; provided, however, that, subject to Section 2(d), the
provisions of Sections 3 and 4 shall become operative only upon the Change in
Control Date.

2.   EMPLOYMENT OF EMPLOYEE.
     ----------------------

     (a) Except as provided in Sections 2(b), 2(c) and 2(d), nothing in this
Agreement shall affect any right which Employee may otherwise have to terminate
Employee's employment, nor shall anything in this Agreement affect any right
which the Company may have to terminate

---------------------
/1/     "Company" shall include the Company, any successor to the Company's
business and/or assets, and any party which executes and delivers the agreement
required by Section 6(e) or which otherwise becomes bound by the terms and
conditions of this Agreement by operation of law or otherwise.
<PAGE>

Employee's employment at any time in any lawful manner.

     (b) In the event of a Potential Change in Control, to be entitled to
receive the benefits provided by this Agreement, Employee will not voluntarily
leave the employ of the Company, and will continue to perform Employee's regular
duties and the services specified in the recitals of this Agreement until the
Change in Control Date.  Should Employee voluntarily terminate employment prior
to the Change in Control Date, this Agreement shall lapse upon such termination
and be of no further force or effect.

     (c) If Employee's employment terminates on or after the Change in Control
Date, the Company will provide to Employee the payments and benefits as provided
in Sections 3 and 4.

     (d) If  Employee's employment is terminated by the Company prior to the
Change in Control Date but on or after a Potential Change in Control Date, then
the Company will provide to Employee the payments and benefits as provided in
Sections 3 and 4 unless the Company reasonably demonstrates that Employee's
termination of employment neither (i) was at the request of a third party who
has taken steps reasonably calculated to effect a Change in Control nor (ii)
arose in connection with or in anticipation of a Change in Control.  Solely for
purposes of determining the timing of payments and the provision of benefits in
Sections 3 and 4 under the circumstances described in this Section 2(d),
Employee's date of termination shall be deemed to be the Change in Control Date.

3.   TERMINATION FOLLOWING CHANGE IN CONTROL.
     ---------------------------------------

     (a) If a Change in Control shall have occurred, Employee shall be entitled
to the benefits provided in Section 4 upon the subsequent termination of
Employee's employment within the applicable period set forth in Section 4 unless
such termination is due to Employee's death, Retirement or Disability or is for
Cause or is effected by Employee other than for Good Reason (as such terms are
defined in Section 3(d)).

     (b) If following a Change in Control, Employee's employment is terminated
by reason of Employee's death or Disability, Employee shall be entitled to death
or long-term disability benefits from the Company no less favorable than the
most favorable benefits to which Employee would have been entitled had the death
or Disability occurred at any time during the period commencing one (1) year
prior to the Change in Control.

     (c) If Employee's employment shall be terminated by the Company for Cause
or by Employee other than for Good Reason during the term of this Agreement, the
Company shall pay Employee's Base Salary through the date of termination at the
rate in effect at the time notice of termination is given, and the Company shall
have no further obligations to Employee under this Agreement.

     (d)  For purposes of this Agreement:

     "Base Salary" shall mean the annual base salary paid to Employee
immediately prior to a

                                       2

annual base salary paid to Employee during the one (1) year period immediately
prior to the Change in Control.

     A "Change in Control" shall be deemed to have occurred if:

     (i) Any individual or group constituting a "person",  as such term is used
in Sections 13(d) and 14(d)(2) of the Exchange Act (other than (A) the Company
or any of its subsidiaries or (B) any trustee or other fiduciary holding
securities under an employee benefit plan of the Company or of any of its
subsidiaries), is or becomes the beneficial owner, directly or indirectly, of
securities of the Company representing thirty percent (30%) or more of the
combined voting power of the Company's outstanding securities then entitled

for the election of directors; or

     (ii) Continuing Directors cease to constitute at least a majority of the
Board; or

     (iii) there occurs a reorganization, merger, consolidation or other

combined voting power of the Company or other corporation resulting from such
Transaction; or

     (iv) all or substantially all of the assets of the Company are sold,
liquidated or distributed;

provided, however, that a "Change in Control" shall not be deemed to have
occurred under this Agreement if, prior to the occurrence of a specified event
that would otherwise constitute a Change in Control hereunder, the disinterested
Continuing Directors then in office, by a majority vote thereof, determine that
the occurrence of such specified event shall not be deemed to be a Change in
Control with respect to Employee hereunder if the Change in Control results from
actions or events in which Employee is a participant in a capacity other than
solely as an officer, employee or director of the Company.

     "Change in Control Date"  shall mean the date on which a Change in Control
occurs.

     "Cause" shall mean:

heard and cure such failure are given to Employee by the Board or a committee
thereof; or

     (ii) The willful commission by Employee of a wrongful act that caused or
was reasonably likely to cause substantial damage to the Company, or an act of

<PAGE>

performance of Employee's duties on behalf of the Company; or

     (iii)  The conviction of Employee for commission of a felony in connection
with the performance of Employee's duties on behalf of the Company; or

     (iv) The order of a federal or state regulatory authority having
jurisdiction over the Company or its operations or by a court of competent
jurisdiction requiring the termination of Employee's employment by the Company.

     "Continuing Directors" shall mean the directors of the Company in office on
the date hereof and any successor to any such director who was nominated or
selected by a majority of the Continuing Directors in office at the time of the
director's nomination or selection and who is not an "affiliate" or "associate"
(as defined in Regulation 12B under the Exchange Act) of any person who is the
beneficial owner, directly or indirectly, of securities representing ten percent
(10%) or more of the combined voting power of the Company's outstanding
securities then entitled ordinarily to vote for the election of directors.

     "Disability" shall mean Employee's incapacity due to physical or mental
illness such that Employee shall have become qualified to receive benefits under

competence of Employee's position with the Company prior to the Change in
Control;

     (ii) requires that Employee serve in a role and perform duties that are
functionally equivalent to the role and duties performed by Employee for the
Company prior to the Change in Control;

     (iii) carries a title that does not connote a lesser rank or corporate
role than is connoted by Employee's title with the Company prior to the Change
in Control;

     (iv) does not constitute a material, adverse change in Employee's
responsibilities or duties, when compare to Employee's responsibilities or
duties with the Company prior to the Change in Control;

                                       4
<PAGE>

senior executives of the Company generally; or

     (iii) The failure to provide to Employee the benefits and perquisites,
including participation on a comparable basis in the Company's stock option,
incentive, and other similar plans in which employees of the Company of
comparable title and salary grade participate, as were provided to Employee
immediately prior to a Change in Control, or with a package of benefits and
perquisites that are substantially comparable in all material respects to such
benefits and perquisites provided prior to the Change in Control; or

     (iv) The relocation of the office of the Company where Employee is employed
immediately prior to the Change in Control Date (the "CIC Location") to a
location which is more than 50 miles away from the CIC Location or the Company's
requiring Employee to be based more than 50 miles away from the CIC Location
(except for required travel on the Company's business to an extent substantially
consistent with Employee's customary business travel obligations in the ordinary
course of business prior to the Change in Control Date);

     (v) The failure of the Company to obtain promptly upon any Change in
Control the express written assumption of an agreement to perform this Agreement
by any successor as contemplated in Section 6(e); or

     (vi) The attempted termination of Employee's employment for Cause on
grounds insufficient to constitute a basis of termination for Cause under this
Agreement; or

consummation of which would result in a Change in Control, or (c) the public
announcement of a tender offer for the Company's voting stock, the completion of
which would result in a Change in Control; provided, that no such event shall be
a "Potential Change in Control" unless (i) in the case of any agreement or
letter of intent described in clause (a), the transaction described therein is
subsequently consummated by the Company and the other party or parties to such
agreement or letter of intent and thereupon constitutes a "Change in Control",
(ii) in the case of any Board-approved transaction described in clause (b), the

Potential Change in Control occurs.

     "Retirement" shall mean Employee's actual retirement after reaching the
normal or early retirement date provided for in the Company's Retirement and

employment.

     (e) Any termination of employment by the Company or by Employee shall be
communicated by written notice, specify the date of termination, state the
specific basis for termination and set forth in reasonable detail the facts and
circumstances of the termination in order to provide a basis for determining the
entitlement to any payments under this Agreement.

     (f) If within thirty (30) days after notice of termination is given, the
party to whom the notice was given notifies the other party that a Dispute
exists, the parties will promptly pursue resolution of such Dispute with
reasonable diligence; provided, however, that pending resolution of any such
Dispute, the Company shall pay 75% of any amounts which would otherwise be due
Employee pursuant to Section 4 if such Dispute did not exist into escrow pending

4.   PAYMENTS AND BENEFITS UPON TERMINATION.
     --------------------------------------

     (a) If within eighteen (18) months after a Change in Control, the Company
terminates Employee's employment other than by reason of Employee's death,
Disability, Retirement or for Cause, or if Employee terminates Employee's
employment for Good Reason, then the Employee shall be entitled to the following
payments and benefits:

     (i) The Company shall pay to Employee as compensation for services
rendered, no later than five (5) business days following the date of
termination, a lump sum

                                       6
<PAGE>

severance payment equal to 2.50 multiplied by the sum of (A) Employee's Base
Salary, (B) the highest annual bonus that was paid to Employee in any of the
three fiscal years ending prior to the date of termination under the Company's
Management Incentive Plan (the "MIP") or Varian Associates, Inc.'s Management
Incentive Plan, and (C) the highest cash bonus for a performance period of more
than one fiscal year that was paid to Employee in any of the three fiscal years
ending prior to the date of termination under the MIP.

     (ii) The Company shall pay to Employee as compensation for services
rendered, no later than five (5) business days following the date of
termination, a lump sum payment equal to a pro rata portion (based on the number
of days elapsed during the fiscal year and/or other bonus performance period in
which the termination occurs) of Employee's target bonus under the MIP for the
fiscal year and for any other partially completed bonus performance period in
which the termination occurs.

     (iii) All waiting periods for the exercise of any stock options granted to
Employee and all conditions or restrictions of any restricted stock granted to
Employee shall terminate, and all such options shall be exercisable in full
according to their terms, and the restricted stock shall be transferred to
Employee as soon as reasonably practicable thereafter.

     (iv) Employee's participation as of the date of termination in the life,
medical/dental/vision and disability insurance plans and financial/tax
counseling plan of the Company shall be continued on the same terms (including
any cost sharing) as if Employee were an employee of the Company (or equivalent
benefits provided) until the earlier of Employee's commencement of substantially
equivalent full-time employment with a new employer or twenty-four (24) months
after the date of termination; provided, however, that after the date of
termination, Employee shall no longer be entitled to receive Company-paid
executive physicals or, upon expiration of the applicable memberships, Company-
paid airline memberships.  In the event Employee shall die before the expiration
of the period during which the Company is required to continue Employee's
participation in such insurance plans, the participation of Employee's surviving
spouse and family in the Company's insurance plans shall continue throughout
such period.

     (v) Employee may elect upon termination to purchase any automobile then in
the possession of Employee and subject to a lease of which the Company is the
lessor by payment to the Company of the residual value set forth in the lease,
without any increase for remaining lease payments during the term or other lease
breakage costs.  Employee may elect to have any such payment deducted from any
payments due the Employee hereunder.

     (vi) All payments and benefits provided under this Agreement shall be
subject to applicable tax withholding.

     (b) Following Employee's termination of employment for any reason, the
Company shall have the unconditional right to reduce any payments owed to
Employee hereunder by the amount of any due and unpaid principal and interest on
any loans by the Company to Employee

                                       7
<PAGE>

and Employee hereby agrees and consents to such right on the part of the
Company.

5.   GROSS-UP PAYMENT.
     ----------------

     (a) Notwithstanding anything herein to the contrary, if it is determined
that any Payment 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
interest or penalties thereon, is herein referred to as an "Excise Tax"), then
Employee shall be entitled to an additional payment (a "Gross-Up Payment") in an
amount that will place Employee in the same after-tax economic position that
Employee would have enjoyed if the Excise Tax had not applied to the Payment.
The amount of the Gross-Up Payment shall be determined by a nationally-
recognized independent public accounting firm designated by agreement between
Employee and the Company (the "Accounting Firm").  No Gross-Up Payments shall be
payable hereunder if the Accounting Firm determines that the Payments are not
subject to an Excise Tax.

     "Payment" means (i) any amount due or paid to Employee under this
Agreement, (ii) any amount that is due or paid to Employee under any plan,
program or arrangement of the Company and its subsidiaries and (iii) any amount
or benefit that is due or payable to Employee under this Agreement or under any
plan, program or arrangement of the Company and its subsidiaries not otherwise
covered under clause (i) or (ii) hereof which must reasonably be taken into
account under Section 280G of the Code in determining the amount the "parachute
payments" received by Employee, including, without limitation, any amounts which
must be taken into account under Section 280G of the Code as a result of (A) the
acceleration of the vesting of any option, restricted stock or other equity
award, (B) the acceleration of the time at which any payment or benefit is
receivable by Employee or (C) any contingent severance or other amounts that are
payable to Employee.

     (b) Subject to the provisions of Section 5(c), all determinations required
under this Section 5, including whether a Gross-Up Payment is required, the
amount of the Payments constituting excess parachute payments, and the amount of
the Gross-Up Payment, shall be made by the Accounting Firm, which shall provide
detailed supporting calculations both to Employee and the Company within fifteen
days of the date reasonably requested by Employee or the Company on which a
determination under this Section 5 is necessary or advisable.  The Company shall
pay to Employee the initial Gross-Up Payment within 5 days of the receipt by
Employee and the Company of the determination of the Accounting Firm.  If the
Accounting Firm determines that no Excise Tax is payable by Employee, the
Company shall cause its accountants to provide Employee with an opinion that the
Accounting Firm has substantial authority under the Code not to report an Excise
Tax on Employee's federal income tax return.  Any determination by the
Accounting Firm shall be binding upon Employee and the Company.  If the initial
Gross-Up Payment is insufficient to cover the amount of the Excise Tax that is
ultimately determined to be owing by Employee with respect to any Payment
(hereinafter an "Underpayment"), the Company, after exhausting its remedies
under Section 5(c) below, shall promptly pay to Employee an additional Gross-Up
Payment in respect of the Underpayment.


                                       8
<PAGE>

     (c) Employee 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 a Gross-Up Payment.  Such notice shall be given as soon as
practicable after Employee knows of such claim and shall apprise the Company of
the nature of the claim and the date on which the claim is requested to be paid.
Employee agrees not to pay the claim until the expiration of the thirty (30) day
period following the date on which Employee notifies the Company, or such
shorter period ending on the date the Taxes with respect to such claim are due
(the "Notice Period").  If the Company notifies Employee in writing prior to the
expiration of the Notice Period that it desires to contest the claim, Employee
shall: (i) give the Company any information reasonably requested by the Company
relating to the claim; (ii) take such action in connection with the claim as the
Company may reasonably request, including, without limitation, accepting legal
representation with respect to such claim by an attorney reasonably selected by
the Company and reasonably acceptable to Employee; (iii) cooperate with the
Company in good faith in contesting the claim; and (iv) permit the Company to
participate in any proceedings relating to the claim.  Employee shall permit the
Company to control all proceedings related to the claim and, at its option,
permit the Company to pursue or forgo any and all administrative appeals,
proceedings, hearings, and conferences with the taxing authority in respect of
such claim.  If requested by the Company, Employee agrees either to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner and
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
Employee to pay such claim and pursue a refund, the Company shall advance the
amount of such payment to Employee on an after-tax and interest-free basis (an
"Advance").  The Company's control of the contest related to the claim shall be
limited to the issues related to the Gross-Up Payment and Employee shall be
entitled to settle or contest, as the case may be, any other issues raised by
the Internal Revenue Service or other taxing authority.  If the Company does not
notify Employee in writing prior to the end of the Notice Period of its desire
to contest the claim, the Company shall pay to Employee an additional Gross-Up
Payment in respect of the excess parachute payments that are the subject of the
claim, and Employee agrees to pay the amount of the Excise Tax that is the
subject of the claim to the applicable taxing authority in accordance with
applicable law.

     (d) If, after receipt by Employee of an Advance, Employee becomes entitled
to a refund with respect to the claim to which such Advance relates, Employee
shall pay the Company the amount of the refund (together with any interest paid
or credited thereon after Taxes applicable thereto).  If, after receipt by
Employee of an Advance, a determination is made that Employee shall not be
entitled to any refund with respect to the claim and the Company does not
promptly notify Employee of its intent to contest the denial of refund, then the
amount of the Advance shall not be required to be repaid by Employee and the
amount thereof shall offset the amount of the additional Gross-Up Payment then
owing to Employee.

     (e) The Company shall indemnify Employee and hold Employee harmless, on an
after-tax basis, from any costs, expenses, penalties, fines, interest or other
liabilities ("Losses") incurred by Employee with respect to the exercise by the
Company of any of its rights under this

                                       9
<PAGE>

Section 5, including, without limitation, any Losses related to the Company's
decision to contest a claim or any imputed income to Employee resulting from any
Advance or action taken on Employee's behalf by the Company hereunder. The
Company shall pay all legal fees and expenses incurred under this Section 5, and
shall promptly reimburse Employee for the reasonable expenses incurred by
Employee in connection with any actions taken by the Company or required to be
taken by Employee hereunder. The Company shall also pay all of the fees and
expenses of the Accounting Firm, including, without limitation, the fees and
expenses related to the opinion referred to in Section 5(b).

6.   GENERAL.
     -------

     (a) Employee shall retain in confidence under the conditions of the
Company's confidentiality agreement with Employee any proprietary or other
confidential information known to Employee concerning the Company and its
business so long as such information is not publicly disclosed and disclosure is
not required by an order of any governmental body or court.  If required,
Employee shall return to the Company any memoranda, documents or other materials
proprietary to the Company.

     (b) While employed by the Company and following the termination of such
employment (other than a termination of employment by Employee for Good Reason
or by the Company other than for Cause) for a period of two (2) years, Employee
shall not, whether for Employee's own account or for the account of any other
individual, partnership, firm, corporation or other business organization,
intentionally solicit, endeavor to entice away from the Company or a subsidiary
of the Company (each, a "Protected Party"), or otherwise interfere with the
relationship of a Protected Party with, any person who is employed by a
Protected Party or any person or entity who is, or was within the then most
recent twelve (12) month period, a customer or client of a Protected Party.

     Employee acknowledges that a breach of any of the covenants contained in
this Section 6(b) may result in material irreparable injury to the Company for
which there is no adequate remedy at law, that it may not be possible to measure
damages for such injuries precisely and that, in the event of such a breach, any
payments remaining under the terms of this Agreement shall cease and the Company
may be entitled to obtain a temporary restraining order and/or a preliminary or
permanent injunction restraining Employee from engaging in activities prohibited
by this Section 6(b) or such other relief as may be required to specifically
enforce any of the covenants in this Section 6(b).  Employee agrees to and
hereby does submit to in personam jurisdiction before each and every such court
in the State of California, County of Santa Clara, for that purpose.  This
Section 6(b) shall survive any termination of this Agreement.

     (c) If litigation is brought by Employee to enforce or interpret any
provision contained in this Agreement, the Company shall indemnify Employee for
Employee's reasonable attorney's fees and disbursements incurred in such
litigation and pay prejudgment interest on any money judgment obtained by
Employee calculated at the prime rate of interest in effect from time to time at
the Bank of America, San Francisco, from the date that payment should have been
made under

                                      10
<PAGE>

the Agreement, provided that Employee shall not have been found by the court in
which such litigation is pending to have had no cause in bringing the action, or
to have acted in bad faith, which finding must be final with the time to appeal
therefrom having expired and no appeal having been taken.

     (d) Except as provided in Section 4, the Company's obligation to pay to
Employee the compensation and to make the arrangements provided in this
Agreement shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, any setoff, counterclaim,
recoupment, defense or other right which the Company may have against Employee
or anyone else.  All amounts payable by the Company hereunder shall be paid
without notice or demand.  Employee shall not be required to mitigate the amount
of any payment provided for in this Agreement by seeking other employment.

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

     (f) This Agreement shall inure to the benefit of and be enforceable by
Employee's heirs, successors and assigns.  If Employee should die while any
amounts would still be payable to Employee hereunder if Employee had continued
to live, all such amounts shall be paid in accordance with the terms of this
Agreement to Employee's heirs, successors and assigns.

     (g) For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed as

or to such other address as either party furnishes to the other in writing in
accordance herewith, except that notices of change of address shall be effective
only upon receipt.

     (h) This Agreement shall constitute the entire agreement between Employee

     (i) The validity, interpretation, construction and performance of this

principles or policies thereof relating to choice or conflict of laws. The
invalidity or unenforceability of any provision of this Agreement in any
circumstance shall not affect the validity or enforceability of such provision
in any other circumstance or the validity or enforceability of any other
provision of this Agreement, and, except to the extent such provision is invalid
or unenforceable, this Agreement shall remain in full force and effect. Any
provision in this Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective only to the extent
of such prohibition or unenforceability without invalidating or affecting the
remaining provisions hereof in such jurisdiction, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. This Section 6(i) shall
survive any termination of this Agreement.

     (j) This Agreement may be terminated by the Company pursuant to a
resolution adopted by the Board at any time prior to a Potential Change in
Control Date.   After a Change in Control Date or a Potential Change in Control
Date, this Agreement may only be terminated with the consent of Employee.

     (k) No agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement and this Agreement
shall supersede all prior agreements, negotiations, correspondence, undertakings
and communications of the parties, oral or written, with respect to the subject
matter hereof including, without limitation, the Amended and Restated Change in
Control Agreement between Employee and the Company dated as of April 2, 1999.

     (l) In the event that the Company becomes party to a transaction that is
intended to qualify for "pooling of interests" accounting treatment and, but for
one or more of the provisions of this Agreement would so qualify, then this
Agreement shall be interpreted so as to preserve such accounting treatment, and
to the extent that any provision of this Agreement would disqualify the
transaction from pooling of interests accounting treatment, then such provision
shall be null and void.  All determinations to be made in connection with the
preceding sentence shall be made by the independent accounting firm whose
opinion with respect to "pooling of interests" treatment is required as a
condition to the Company's consummation of such transaction.
