forth.

Act of 1974, as amended ("ERISA"). Benefits, if payable under the Plan,
generally will be payable prior to termination of employment.

                      SELECTION, ENROLLMENT AND ELIGIBILITY

2.1        SELECTION BY COMMITTEE. Participation in the Plan shall be limited to
           a select group of management and highly compensated employees of the
           Employers. From that group, the Committee shall select, in its sole
           discretion, employees to participate in the Plan.

2.2        ENROLLMENT REQUIREMENTS. As a condition to participation, each
           selected employee shall complete, execute and return to the Committee
           a Plan Agreement and a Beneficiary Designation Form. In addition, the
           Committee, in its sole discretion, shall establish from time to time
           such other enrollment requirements as it determines are necessary.

2.3        ELIGIBILITY; COMMENCEMENT OF PARTICIPATION. Provided an employee
           selected to participate in the Plan has met all enrollment
           requirements set forth in this Plan and required by the Committee,
           that employee shall commence participation in the Plan on the date
           specified by the Committee. If a selected employee fails to meet all
           such requirements prior to that date, that employee shall not be
           eligible to participate in the Plan until the completion of those
           requirements.

                            VESTING; ACCOUNT BALANCE

3.1        VESTING IN CHANGE IN CONTROL BENEFIT.  Subject to Section 3.2 below:

           (a)      General Rule. If a Participant has not forfeited his or her
                    benefits pursuant to Section 3.2(a)(i) below, or experienced
                    a Termination of Employment, prior to 90 days prior to a
                    Change in Control, the Participant shall become 100% vested
                    in his or her Change in Control Benefit on the date six
                    months following the Change in Control (the "Vesting Date").

           (b)      Early Vesting. If at any time on or after 90 days prior to a
                    Change in Control and prior to the Vesting Date a
                    Participant Retires, dies, suffers a Disability or
                    experiences an involuntarily termination of employment with
                    all Employers, the Participant (or the Participant's
                    Beneficiary in the event of the Participant's death) shall
                    become 100% vested in his or her Change in Control Benefit
                    on the later of (i) the date of the Change in Control or
                    (ii) the date of such Retirement, death, Disability or
                    involuntary termination of employment, and such date (rather
                    than the date six months following a Change in Control)
                    shall be considered the "Vesting Date" for purposes of this
                    Plan.

3.2        FORFEITURE. Notwithstanding Section 3.1 above, a Participant shall
           forfeit any right to benefits under this Plan in accordance with this
           Section 3.2:

           (a) A Participant shall forfeit any right to benefits under this Plan
if he or she:

                    (i)    Retires, dies, suffers a Disability, or experiences a
                           Termination of Employment, in each case prior to 90
                           days before a Change in Control, or receives lump sum
                           distributions from the Supplemental Retirement Plans
                           that permanently ends his or her participation in the
                           Supplemental Retirement Plans (a "Termination
                           Distribution") at any time; or

                    (ii)   Voluntarily terminates his or her employment (other
                           than by Retirement or Disability) with all of his or
                           her Employers or receives a Termination Distribution
                           from the Supplemental Retirement Plans at any time on
                           or after the date of a Change in Control and prior to
                           the date six months following the Change in Control.

           (b)      A Participant receiving payments or other partial
                    distributions from the Supplemental Retirement Plans before
                    his or her Vesting Date described in Section 3.1(a) hereof
                    shall forfeit a portion of his or her Change in Control
                    Benefit which bears the same proportion to all of such
                    benefit as the payment or partial distribution bears to his
                    or her total interest in the Supplemental Retirement Plans.

3.3        ACCOUNT BALANCE. Within 60 days of the end of each Plan Year, each
           Participant shall receive a statement setting forth the balance of
           his or her Participant's Account as of the end of that Plan Year.

4.1        CHANGE IN CONTROL BENEFIT.

           (a)      Eligibility. On the Vesting Date, the Participant or the
                    Participant's Beneficiary, as the case may be, shall become
                    entitled to the "Change in Control Benefit" described in
                    Section 4.1(b).

           (b)      Benefit and Payment. The "Change in Control Benefit" shall
                    be a dollar amount that is equal to the fair market value of
                    the assets allocated to and held in the Participant's
                    Account as of the Vesting Date. This benefit shall be paid
                    to the Participant, or his or her Beneficiary, within 90
                    days of the Vesting Date.

4.2        EMPLOYER BENEFIT.

           (a)      Eligibility. Subject to Section 4.4 below, the Participant's
                    Employer shall be entitled to the Employer Benefit if and to
                    the extent a Participant forfeits his or her Change in
                    Control Benefit under Section 3.2 above.

           (b)      Benefit and Payment. Subject to Section 4.4 below, the
                    "Employer Benefit" shall be a distribution of the assets
                    allocated to and held in the Participant's Account as of the
                    date of the event described in Section 3.2 above after
                    taking in account any distributions made or to be made in
                    accordance with Section 4.1 above, plus any earnings
                    allocated to that account from that date to the date of
                    payment of the Employer Benefit. This benefit shall be paid
                    to the Participant's Employer within 120 days of January 1
                    of the Plan Year following that event.

4.3        WITHHOLDING AND PAYROLL TAXES. The Trustee shall withhold from any
           and all benefit payments made under this Article 4, all federal,
           state and local income, employment and other taxes required to be
           withheld in connection with the payment of benefits hereunder, in
           amounts to be determined in the sole discretion of the Participant's
           Employer.

4.4        ALLOCATION OF CERTAIN FORFEITED BENEFITS TO RESERVE ACCOUNT.
           Notwithstanding Section 4.2 above, if upon the occurrence of an event
           described in Section 3.2 the Account of the Participant involved
           holds a fractional interest in a Policy, such interest in such Policy
           shall be reallocated to the Reserve Account rather than distributed
           as an Employer Benefit. If at any time the Reserve Account holds 100%
           of the interests in a Policy as a result of the application of the
           preceding sentence, such Policy shall be distributed to the
           appropriate Employers as an Employer Benefit as soon as reasonably
           practical.


                                    ARTICLE 5
                                   BENEFICIARY

5.1        BENEFICIARY. Each Participant shall have the right, at any time, to
           designate his or her Beneficiary (both primary as well as contingent)
           to receive any benefits payable under the Plan to a Beneficiary upon
           the death of a Participant.

5.2        BENEFICIARY DESIGNATION; CHANGE; SPOUSAL CONSENT. A Participant shall
           designate his or her Beneficiary by completing and signing the
           Beneficiary Designation Form, and returning it to the Committee or
           its designated agent. A Participant shall have the right to change a
           Beneficiary by completing, signing and otherwise complying with the
           terms of the Beneficiary Designation Form and the Committee's rules
           and procedures, as in effect from time to time. If the Participant
           names someone other than his or her spouse as a Beneficiary, a
           spousal consent, in the form designated by





                                        7

<PAGE>   12




           the Committee, must be signed by that Participant's spouse and
           returned to the Committee. Upon the acceptance by the Committee of a
           new Beneficiary Designation Form, all Beneficiary designations
           previously filed shall be canceled. The Committee shall be entitled
           to rely on the last Beneficiary Designation Form filed by the
           Participant and accepted by the Committee before his or her death.

5.3        ACKNOWLEDGMENT. No designation or change in designation of a
           Beneficiary shall be effective until received, accepted and
           acknowledged in writing by the Committee or its designated agent.

5.4        NO BENEFICIARY DESIGNATION. If a Participant fails to designate a
           Beneficiary as provided in Sections 5.1, 5.2 and 5.3 above, or if all
           designated Beneficiaries predecease the Participant or die prior to
           complete distribution of the Participant's benefits, then the
           Participant's designated Beneficiary shall be deemed to be his or her
           surviving spouse. If the Participant has no surviving spouse, the
           benefits remaining under the Plan to be paid to a Beneficiary shall
           be payable to the executor or personal representative of the
           Participant's estate.

5.5        DOUBT AS TO BENEFICIARY. If the Committee has any doubt as to the
           proper Beneficiary to receive payments pursuant to this Plan, the
           Committee shall have the right, exercisable in its discretion, before
           a Change in Control, to cause the Trustee to withhold such payments
           until this matter is resolved to the Committee's satisfaction.

5.6        DISCHARGE OF OBLIGATIONS. The payment of benefits under the Plan to a
           Beneficiary shall fully and completely discharge all Employers and
           the Committee from all further obligations under this Plan with
           respect to the Participant, and that Participant's Plan Agreement
           shall terminate upon such full payment of benefits.

                            TERMINATION, AMENDMENT OR
                            MODIFICATION OF THE PLAN

6.1        TERMINATION, AMENDMENT OR MODIFICATION PRIOR TO ONE YEAR BEFORE
           CHANGE IN CONTROL. Subject to Section 6.2, each Employer reserves the
           right to terminate, amend or modify the Plan or any related Plan
           Agreement, in whole or in part, with respect to Participants whose
           services are retained by that Employer. Notwithstanding the
           foregoing, no termination, amendment or modification shall be
           effective to decrease or reduce a Participant's potential benefits
           under this Plan below the balance in his or her Participant's Account
           as of the effective date of the termination, amendment or
           modification.

6.2        TERMINATION, AMENDMENT OR MODIFICATION WITHIN ONE YEAR BEFORE CHANGE
           IN CONTROL OR FOLLOWING CHANGE IN CONTROL. Within one year before a
           Change in Control and thereafter, neither the Company, any subsidiary
           of the Company nor any corporation, trust or other person that
           succeeds to all or any substantial portion of the assets of the
           Company shall have the right to terminate, amend or modify the Plan
           and/or any Plan Agreement in effect prior to such Change in Control,
           and all benefits under the Plan and any such Plan Agreement shall
           thereafter be paid in accordance with the terms of the Plan and such
           Plan Agreement, as in effect immediately prior to such Change in
           Control. If the Plan is terminated, amended, or modified within one
           year before a Change in Control, such termination, amendment or
           modification shall be considered void as of the date of the
           termination, amendment or modification. Any provision of this Plan or
           any Plan Agreement to the contrary shall be construed in accordance
           with this Section 6.2.

6.3        TERMINATION OF PLAN AGREEMENT. Absent the earlier termination,
           modification or amendment of the Plan, or a Participant's Forfeiture
           of his or her benefits under this Plan, the Plan Agreement of any
           Participant shall terminate upon the full payment of the applicable
           benefit provided under Article 4.


                                    ARTICLE 7
                          OTHER BENEFITS AND AGREEMENTS

7.1        COORDINATION WITH OTHER BENEFITS. The benefits provided for a
           Participant and Participant's Beneficiary under the Plan are in
           addition to any other benefits available to such Participant under
           any other plan or program for employees. The Plan shall supplement
           and shall not supersede, modify or amend any other such plan or
           program except as may otherwise be expressly provided.


                                    ARTICLE 8
                                      TRUST

8.1        ESTABLISHMENT OF THE TRUST; PREMIUMS. The Company shall establish the
           Trust and the Employers shall, at least annually, transfer over to
           the Trust such assets, if any, as the Company determines, in its sole
           discretion, to contribute or cause to be contributed to the Trust
           prior to a Change in Control. The Committee may direct, prior to a
           Change in Control, payment of any and all Policy premiums and other
           costs relating to insurance policies owned by the Trust. In addition,
           if the Trust incurs any tax liability, the Employers shall contribute
           to the Trust sufficient funds to allow the Trustee to pay any such
           tax liability.

8.2        INTERRELATIONSHIP OF THE PLAN AND THE TRUST. The provisions of the
           Plan and each Plan Agreement shall govern the rights of a Participant
           to receive distributions pursuant to the Plan. The provisions of the
           Trust shall govern the rights of the





                                        9

<PAGE>   14




           Trustee, Participant and a Participant's Beneficiary as to the assets
           of the Trust. The Employers shall at all times remain liable to carry
           out their obligations under the Plan. The Employers and the Trustee
           shall cooperate with each other as is necessary to minimize the
           Trust's tax liability.

8.3        ACCOUNTS.

           (a)       The Trustee shall establish and maintain the following
                     separate accounts:

                     (i)    A "Participant's Account" for each Participant (A)
                            to which the Employers' contributions, or a portion
                            thereof, may be allocated and held, (B) to which the
                            earnings on amounts held pursuant to (A) shall be
                            allocated and held, (C) to which amounts from the
                            Reserve Account may be allocated and held, and (D)
                            to which the earnings on amounts held pursuant to
                            (C) shall be allocated and held, the assets of which
                            are to be used to pay the Change in Control Benefit
                            or the Employer Benefit in accordance with this Plan
                            and the Trust;

                     (ii)   An "Administrative Account" for the administrative
                            expenses of the Trust to which a portion of the
                            Employers' contributions and earnings thereon and
                            the Reserve Account and earnings and gains thereon
                            may be allocated to and held, the assets of which
                            are to be used to pay the administrative expenses,
                            including all taxes, of the Trust in accordance with
                            the terms and provisions of this Plan and the Trust
                            that are not paid directly by the Employers; and

                     (iii)  A "Reserve Account" to which shall be allocated (i)
                            the gains constituting, in the case of a Policy (or
                            a portion thereof) on the life of a Participant that
                            is allocated to the Participant's Account of another
                            Participant, the excess of the life insurance
                            proceeds of such Policy over the cash value thereof
                            (appropriately pro rated in the case of a Policy
                            fractional interests in which are allocated to more
                            than one Participant's Accounts) and (ii) fractional
                            interests in Policies pursuant to Section 4.4 above.
                            Assets so allocated to and held in the Reserve
                            Account shall be allocated or reallocated to other
                            Participant's Accounts or the Administrative
                            Account, or shall be distributed as an Employer
                            Benefit, in accordance with the terms of the Plan.

           (b)      Prior to a Change in Control, the Committee shall, in its
                    sole discretion, direct the Trustee in writing as to the
                    allocation of (i) the Employers' contributions to the
                    accounts described in Section 8.3(a) above, (ii) the
                    earnings on the Employer's contributions held in the
                    accounts described in Section 8.3(a) above, and (iii) gains
                    allocated to the Reserve Account in accordance with Section
                    8.3(d) below or fractional interests in Policies allocated
                    to the Reserve Account in accordance with Section 4.4. After
                    a

                    Change in Control, the Trustee shall make such allocations
                    in accordance with the terms of the Plan and the Trust.
                    Notwithstanding the foregoing, and except for a payment of
                    benefits in accordance with Article 4 or a Forfeiture of
                    benefits, a Participant's Account balance shall not be
                    reduced.

           (c)      Each of the accounts described in Section 8.3(a) above shall
                    qualify for and be treated as a separate share under Code
                    Section 663(c).

           (d)      Notwithstanding the foregoing, for purposes of this Plan, in
                    the case of a Policy (or a portion thereof) on the life of a
                    Participant that is allocated to the Participant's Account
                    of another Participant:

                    (i)     In the event of the death of the Participant whose
                            life is insured by such Policy, the excess of the
                            life insurance proceeds of the Policy over the cash
                            value thereof on the date of death of such
                            Participant (appropriately pro rated in the case of
                            a Policy fractional interests in which are allocated
                            to more than one Participant's Accounts) shall
                            constitute a gain allocable to the Reserve Account;
                            and

                     (ii)   The additions to the cash value thereof
                            (appropriately pro rated in the case of a Policy
                            fractional interests in which are allocated to more
                            than one Participant's Accounts) shall constitute
                            income allocable to the Account to which such Policy
                            (or a portion thereof) has (except for the right to
                            such gain) been allocated.

           individual serving on the Committee who is a Participant shall not
           vote or act on any matter relating solely to himself or herself. When
           making a determination or calculation, the Committee shall be
           entitled to rely on information furnished by a Participant or the
           Company.

10.2       AGENTS. In the administration of this Plan, the Committee may, from
           time to time, employ agents and delegate to them such administrative
           duties as it sees fit (including acting through a duly appointed
           representative) and may from time to time consult with counsel who
           may be counsel to any Employer.

10.3       BINDING EFFECT OF DECISIONS. The decision or action of the Committee
           with respect to any question arising out of or in connection with the
           administration, interpretation and application of the Plan and the

           conclusive and binding upon all persons having any interest in the
           Plan.

10.4       INDEMNITY OF COMMITTEE. All Employers shall indemnify and hold
           harmless the members of the Committee against any and all claims,
           losses, damages, expenses or liabilities arising from any action or
           failure to act with respect to this Plan, except in the case of
           willful misconduct by the Committee or any of its members.

10.5       EMPLOYER INFORMATION. To enable the Committee to perform its
           functions, each Employer shall supply full and timely information to
           the Committee on all matters relating to the compensation of its
           Participants, the date and circumstances of the Retirement,
           Disability, death or Termination of Employment of its Participants,
           and such other pertinent information as the Committee may reasonably
           require.

11.1       PRESENTATION OF CLAIM. Any Participant or Beneficiary of a deceased
           Participant (such Participant or Beneficiary being referred to below
           as a "Claimant") may deliver to the Committee a written claim for a
           determination with respect to the amounts

           distributable to such Claimant from the Plan. If such a claim relates
           to the contents of a notice received by the Claimant, the claim must
           be made within 60 days after such notice was received by the
           Claimant. All other claims must be made within 180 days of the date
           on which the event that caused the claim to arise occurred. The claim
           must state with particularity the determination desired by the
           Claimant.

11.2       NOTIFICATION OF DECISION. The Committee shall consider a Claimant's
           claim within 60 days of receipt of that claim, and shall notify the
           Claimant in writing:

           (a)      that the Claimant's requested determination has been made, 
                    and that the claim has been allowed in full; or

           (b)      that the Committee has reached a conclusion contrary, in
                    whole or in part, to the Claimant's requested determination,
                    and such notice must set forth in a manner calculated to be
                    understood by the Claimant:

                    (i)     the specific reason(s) for the denial of the claim,
                            or any part of it;

                    (ii)    the specific reference(s) to pertinent provisions of
                            the Plan upon which such denial was based;

                    (iii)   a description of any additional material or
                            information necessary for the Claimant to perfect
                            the claim, and an explanation of why such material
                            or information is necessary; and

                    (iv)    an explanation of the claim review procedure set
                            forth in Section 11.3 below.

11.3       REVIEW OF A DENIED CLAIM. Within 60 days after receiving a notice
           from the Committee that a claim has been denied, in whole or in part,
           a Claimant (or the Claimant's duly authorized representative) may
           file with the Committee a written request for a review of the denial
           of the claim. Thereafter, but not later than 30 days after the review
           procedure began, the Claimant (or the Claimant's duly authorized
           representative):

           (a)        may review pertinent documents;

           (b)        may submit written comments or other documents; and/or

           (c)        may request a hearing, which the Committee, in its sole
                      discretion, may grant.

11.4       DECISION ON REVIEW. The Committee shall render its decision on review
           promptly, and not later than 60 days after the filing of a written
           request for review of the denial, unless a hearing is held or other
           special circumstances require additional time, in which case the
           Committee's decision must be rendered within 120 days after such





                                       13

<PAGE>   18




           date. Such decision must be written in a manner calculated to be
           understood by the Claimant, and it must contain:

           (a)      specific reasons for the decision;

           (b)      specific reference(s) to the pertinent Plan provisions upon
                    which the decision was based; and

           (c)      such other matters as the Committee deems relevant.

11.5       LEGAL ACTION. A Claimant's compliance with the foregoing provisions
           of this Article 11 is a mandatory prerequisite to a Claimant's right
           to commence any legal action with respect to any claim for benefits
           under this Plan.


                                   ARTICLE 12
                                  MISCELLANEOUS

12.1       UNSECURED GENERAL CREDITOR. Participants and their Beneficiaries,
           heirs, successors and assigns shall have no legal or equitable
           rights, interest or claims in any property or assets of an Employer.
           Any and all of an Employer's assets shall be, and remain, the
           general, unpledged and unrestricted assets of the Employer. An
           Employer's obligation under the Plan shall be merely that of an
           unfunded and unsecured promise to pay money in the future.

12.2       EMPLOYER'S LIABILITY. An Employer's liability for the payment of
           benefits shall be defined only by the Plan and the Plan Agreement, as
           entered into between the Employer and a Participant. An Employer
           shall have no obligation to a Participant under the Plan except as
           expressly provided in the Plan and his or her Plan Agreement.

12.3       NONASSIGNABILITY. Neither a Participant nor any other person shall
           have any right to commute, sell, assign, transfer, pledge,
           anticipate, mortgage or otherwise encumber, transfer, hypothecate or
           convey in advance of actual receipt, the amounts, if any, payable
           hereunder, or any part thereof, which are, and all rights to which
           are expressly declared to be unassignable and non-transferable. No
           part of the amounts payable shall, prior to actual payment, be
           subject to seizure or sequestration for the payment of any debts,
           judgments, alimony or separate maintenance owed by a Participant or
           any other person, nor be transferable by operation of law in the
           event of a Participant's or any other person's bankruptcy or
           insolvency or be transferable to a spouse as a result of a property
           settlement or otherwise.

12.4       NOT A CONTRACT OF EMPLOYMENT. The terms and conditions of this Plan
           shall not be deemed to constitute a contract of employment between
           any Employer and the Participant. Such employment is hereby
           acknowledged to be an "at will"





                                       14

<PAGE>   19




           employment relationship that can be terminated at any time for any
           reason, with or without cause, unless expressly provided in a written
           employment agreement. Nothing in this Plan shall be deemed to give a
           Participant the right to be employed in the service of any Employer,
           or to interfere with the right of any Employer to discipline or
           discharge the Participant at any time.

12.5       FURNISHING INFORMATION. A Participant will cooperate with the
           Committee by furnishing any and all information requested by the
           Committee and take such other actions as may be requested in order to
           facilitate the administration of the Plan and the payments of
           benefits hereunder, including but not limited to taking such physical
           examinations as the Committee may deem necessary.

12.6       TERMS. Whenever any words are used herein in the singular or in the
           plural, they shall be construed as though they were used in the
           plural or the singular, as the case may be, in all cases where they
           would so apply.

12.7       CAPTIONS. The captions of the articles, sections and paragraphs of
           this Plan are for convenience only and shall not control or affect
           the meaning or construction of any of its provisions.

12.8       GOVERNING LAW. The provisions of this Plan shall be construed and
           interpreted according to the laws of the State of Ohio.

12.9       VALIDITY. In case any provision of this Plan shall be illegal,
           invalid or ineffective for any reason, said illegality, invalidity or
           ineffectiveness shall not affect the remaining parts hereof, but this
           Plan shall be construed and enforced as if such illegal, invalid
           and/or ineffective provision had never been inserted herein.

12.10      NOTICE. Any notice or filing required or permitted to be given to the
           Committee under this Plan shall be sufficient if in writing and
           hand-delivered, or sent by registered or certified mail or recognized
           overnight courier, to the address below:

                    Allen Telecom Inc.
                    25101 Chagrin Boulevard
                    Beachwood, OH  44122-5169
                    Attention:  General Counsel

           Such notice shall be deemed given as of the date of delivery or, if
           delivery is made by mail, as of the date shown on the postmark on the
           receipt for registration or certification.

           Any notice or filing required or permitted to be given to a
           Participant under this Plan shall be sufficient if in writing and

           Participant.

12.11      SUCCESSORS. The provisions of this Plan shall bind and inure to the
           benefit of the Participant's Employer and its successors and assigns
           and the Participant, the Participant's Beneficiaries, and their
           permitted successors and assigns.

12.12      SPOUSE'S INTEREST. The interest in the benefits hereunder of a spouse
           of a Participant who has predeceased the Participant shall
           automatically pass to the Participant and shall not be transferable
           by such spouse in any manner, including but not limited to such
           spouse's will, nor shall such interest pass under the laws of
           intestate succession.

12.13      INCOMPETENT. If the Committee determines in its discretion that a
           benefit under this Plan is to be paid to a minor, a person declared
           incompetent or to a person incapable of handling the disposition of
           that person's property, the Committee may direct payment of such
           benefit to the guardian, legal representative or person having the
           care and custody of such minor, incompetent or incapable person. The
           Committee may require proof of minority, incompetency, incapacity or
           guardianship, as it may deem appropriate prior to distribution of the
           benefit. Any payment of a benefit shall be a payment for the account
           of the Participant and the Participant's Beneficiary, as the case may
           be, and shall be a complete discharge of any liability under the Plan
           for such payment amount.

12.14      DISTRIBUTION IN THE EVENT OF TAXATION. If, for any reason, all or any
           portion of a Participant's benefit under this Plan becomes taxable to
           the Participant prior to the Vesting Date, a Participant may petition
           the Committee, if prior to a Change in Control, or the Trustee, after
           a Change in Control, for a distribution of assets sufficient to meet
           the Participant's tax liability (including additions to tax,
           penalties and interest). Upon the grant of such a petition, which
           grant shall not be unreasonably withheld, the Trustee shall
           distribute to the Participant from the Trust immediately available
           funds in an amount equal to that Participant's federal, state and
           local tax liability associated with such taxation, which liability
           shall be measured by using that Participant's then current highest
           federal, state and local marginal tax rate,





                                       16



<PAGE>   21


           plus the rates or amounts for the applicable additions to tax,
           penalties and interest. If the petition is granted, the tax liability
           distribution shall be made within 90 days of the date when the
           Participant's petition is granted.


                    IN WITNESS WHEREOF the Company has signed this Plan document
as of the 24th day of November, 1997.
