                               GENERAL PROVISIONS
                               ------------------

     1.01 Synopsis.  This Agreement sets forth the Supplemental Executive
          --------
Retirement Plan (the "SERP") established and maintained by Trans-Lux Corporation
(the "Company") generally to provide benefits for participants in the Retirement
Pension Plan for Employees of Trans-Lux Corporation and Certain of its
Subsidiaries and/or Affiliates (the "Plan") equal to the benefit that cannot be
paid under the Retirement Plan because of the limits in Sections 401(a)(17) and
415 of the Code and other restrictions.  The Plan is unfunded and benefits shall
be paid from the general funds of the Company.  The Plan is primarily for the
purpose of providing deferred compensation for a select group of management or
highly compensated employees.  Benefits are not intended to be taxable to a
Participant until the benefits are actually received.  The Plan is intended to
comply with Code Section 409A and implementing regulations.  The Administrator
shall interpret and implement this Plan in a manner consistent with its purpose
and intent.

To the extent a Participant has an employment agreement with the Company
providing for ASRB payments, this Agreement does not increase the amount of any
such payments, provided, however, the form of payment permitted by Section 4.02
may be greater than that permitted under the Retirement Plan because of
financial restrictions then applicable to the Retirement Plan.  In the event of
any other conflict between this Agreement and such employment agreement, this
Agreement shall govern.

                                   ARTICLE IV

                                    BENEFITS
                                    --------

     4.01 Benefits.  The Company will pay to the Participant on the first day of
          --------
the seventh month following the earlier of the Participant's Normal Retirement
Date, Earlier Retirement Date, Disability Retirement or Deferred Retirement
Date, an amount (the "Excess Benefit") equal to an annuity for the life of the
Participant of (a) minus (b) below:

     a.  The Accrued Benefit determined under Plan Section 4.1 (for payments
commencing on or after the Participant's Normal Retirement Date or Deferred
Retirement Date), Plan Section 4.2 (for payments commencing at the Participant's
Earlier Retirement Date) or Plan Section 10.2 (for payment on account of the
Participant's Disability Retirement) but without regard to (i) the limitations
on the maximum annual benefits imposed by Code Section 415, (ii) the limitations
on the amount of annual compensation which may be taken into account under Code
Section 401(a)(17), (iii) any further limitations in benefits under the Plan
resulting from statutory changes or from modifications in the Plan required by
statutory changes after December 31, 2001, or (iv) the discontinuation of the
Plan or the accrual of benefits thereunder following a Change of Control.

     b.  The Accrued Benefit payable under the Retirement Plan.

     4.02 Form of Benefits.  The Excess Benefit shall be paid in the form of a
          ----------------
lump sum payment that is actuarially equivalent to the Excess Benefit (expressed
as a single life annuity), as conclusively determined by the Company in
accordance with interest, mortality and other assumptions being used at that
time in connection with the Plan.  Notwithstanding the foregoing, the
Participant may elect any alternate form of payment available under the
Retirement Plan, provided that the election is made at least one year prior to
the date benefits would otherwise commence under the terms of this Agreement
and, provided further that the first payment under the alternate form of payment
is not less than five years from the date the lump sum payment would have been
paid.

     4.03 Death Benefits.  If a Participant dies before the Excess Benefit
          --------------
commences hereunder, and is survived by a Spouse, then the Company shall pay to
the surviving Spouse an annuity equal to 50% of the Excess Benefit that would
have been payable to the Participant had the Participant terminated from
employment on the day before his death, survived to his earliest retirement age,
elected Earlier Retirement and a 50% Joint and Survivor benefit (as defined by
the Retirement Plan), and then died.  Notwithstanding the foregoing, if the
Participant had attained Earliest Retirement Date on the date of death, the
survivor benefit described in the foregoing sentence shall be determined as is
the Participant had retired on the date of death and Section 4.2 of the Plan
applied.  Such annuity shall be payable for the life of the Participant's
surviving spouse, with monthly payments commencing on the first day of the month
coincident with or next following the later of (i) the date of the Participant's
death, or (ii) the date the Participant would have attained age 55 if the
Participant had completed 10 Years of Credited Service as of the date of death.

                                       5

     The provisions of Plan Section 7.1 (relating to the reduction in benefits
for young Spouses and the single sum payment of small benefits) shall apply to
the death benefit under the SERP in the same manner as applies under the Plan.

                                 ADMINISTRATION
                                 --------------

     5.01 Source of Benefits.  Benefits shall be paid from the general assets of
          ------------------
the Company and shall not be funded, by trust or otherwise, except that in the
discretion of the Company a so-called "rabbi trust" may be used to facilitate
payment of Plan benefits and to serve as a repository for earmarked funds.  No
Participant or surviving Spouse shall have a right to payment of plan benefits
greater than that of a general creditor of the Company.  Nothing herein shall be
deemed to create a trust of any kind or to create any fiduciary relationship
with respect to any assets whatsoever.

     5.02 Alienation of Benefits.  Benefits are not subject to alienation,
          ----------------------
anticipation or assignment by a Participant or surviving Spouse and to the
maximum extent permitted by law, are not subject to being attached or reached
and applied by any creditor.  In the event a Participant's benefits under the
Plan are garnished or attached by an order of any court, the Administrator may
bring an action for a declaratory judgment in a court of competent jurisdiction
to have the order declared unenforceable against the Plan because of the general
prohibition of the assignment or alienation of Plan Benefits contained in this
Section 4.02.  During the pendency of the action, any benefits that become
payable may be paid to the court for distribution by the court to the recipient
that the court determines to be proper.

     5.03 Withholding.  Payments under the Plan shall be adjusted to
          -----------
appropriately reflect any applicable income tax withholding requirements,
payroll taxes, or other deductions authorized by the Company in accordance with
its policies.  Any additional taxes payable by the Participant on any ASRB
payment as a result of the inability to pay the ASRB benefit under the Plan
shall be paid by the Company to the Participant and grossed up in such manner to
offset the effect of the Participant's state and federal income taxes on such
payment.

     5.04 Payments to Legal Incompetents.  Upon proof satisfactory to the
          ------------------------------
Administrator that any person entitled to receive a payment under the plan is
legally incompetent to receive the payment, the Administrator may direct the
payment to be made to the guardian or conservator or other personal
representative of the estate of the person.

     5.05 Correction of Mistakes.  Any mistake in the amount of a Participant's
          ----------------------
benefits under the plan may be corrected by the Administrator when the mistake
is discovered.  The mistake may be corrected in any reasonable manner authorized
by the Administrator (e.g., where a mistake is not timely discovered), or the
Administrator may waive the making of any correction.  A Participant or
Beneficiary receiving an overpayment by mistake shall repay the overpayment if
requested to do so by the Administrator.

     5.06 Claims and Review.
          -----------------

     a.  Written Claim is Not Required.  Ordinarily, ASRB benefits will be paid
         -----------------------------
to Participants or their surviving Spouses without their having to file a claim
or take any other action.  If a Participant or surviving Spouse does not receive
payment of benefits which the Participant or

                                       7
<PAGE>

Spouse believes are due under the SERP, the Participant or Spouse may file a
written claim for benefits with the Administrator.  The written claim shall be
in a form satisfactory to and with such supporting documents and information as
may be required by the Administrator.

     b.  Notice of a Claim Denial.  If a claim for benefits under the SERP is
         ------------------------
denied in whole or in part by the Administrator, the claimant shall be notified
in writing within a reasonable period of time following the denial.  The notice
shall set forth:

         i.    the reasons for the denial of the claim;

         ii.   a reference to the provisions of the SERP on which the denial is
               based;

         iii.  any additional material or information necessary to perfect the
               claim and an explanation why they are necessary; and

         iv.   a reference to the procedures for review of the denial of the
               claim set forth in Section 5.06(c).

     c.  Right to Review of the Denial.  Every person whose claim for benefits
         -----------------------------
under the SERP is denied in whole or in part by the Administrator shall have the
right to request a review of the denial.  A claim which has not been approved or
denied by the Administrator within 90 days of the date it was filed shall be
deemed to be denied and the claimant shall have the right to request a review of
the denial.  Review shall be granted if it is requested in writing by the
claimant no later than 60 days after the claimant receives written notice of the
denial.  The review shall be conducted by the Administrator.

     d.  Decision on Review.  With respect to any requested claim review, the
         ------------------
claimant shall have an opportunity to submit and review pertinent documents and
may submit a written statement.  The Administrator shall render its decision as
soon as practicable.  Ordinarily decisions shall be rendered within 60 days
following receipt of the request for review.  If special circumstances require
additional processing time, the decision shall be rendered as soon as possible
but not later than 120 days following receipt of the request for review.  The
Administrator's decision shall be in writing, shall set forth the reasons for
the decision and the provisions of the Plan on which it is based and shall be
communicated to the claimant.  The Administrator's decision shall be final and
binding on the claimant, and the claimant's heirs, assigns, administrator,
executor and any other person claiming through the claimant.

     5.07 Company Actions.  Whenever the Board of Directors is required or
          ---------------
permitted to take any action under the terms of the Plan, it may be taken by
resolution voted by the Board of Directors.  Such action may also be taken by
any officer, employee, or agent of the Company duly authorized to take such
action by the Company's Board of Directors.

     5.08 Administrator.  The Administrator shall operate, interpret, and
          -------------
implement the plan.  The Administrator's decisions and determinations (including
determinations of the meaning and reference of terms used in this Plan) that are
not arbitrary and capricious shall be conclusive upon all persons.  The
Administrator shall be the Named Fiduciary for purposes of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA").

     6.01 Intent.  This Plan is intended to be unfunded and maintained by the
          ------
Company primarily for the purpose of providing deferred compensation for a
select group of management or highly compensated employees within the meaning of

          -------------

          ------------------------
terminated except by written agreement of the Participant and the Company.  The
Board of Directors of Trans-Lux Corporation shall have the exclusive authority,
which authority may not be delegated, to act for the Company to amend the SERP
and to terminate the SERP.

     6.04 No Contract of Employment.  This Plan shall not constitute an express
          -------------------------
or implied contract of employment between the Company and any Participant.

          ------------------------

          -----------------------------------------------

     a.  Communications to Participant.  All notices, reports and other

the Participant's Plan benefits

<PAGE>

but shall have no right to inspect Plan records generally or as they relate to
the Plan benefits or other Participants.

     6.07 Severability.  If any term or provision hereof is determined to be
          ------------
invalid or unenforceable in a final court or arbitration proceeding, (a) the
remaining terms and provisions hereof shall be unimpaired and (b) the invalid or
unenforceable term or provision shall be deemed replaced by a term or provision
that is valid and enforceable and that comes closest to expressing the intention
of the invalid or unenforceable term or provision.

          ------------------------------
SERP document has been executed on behalf of the Company by the undersigned duty
