                        SUPPLEMENTAL RETIREMENT AGREEMENT


            THIS AGREEMENT is made and entered into this 8th day of May, 1996 by
and between SpecTran Corporation ("SpecTran"), a Delaware corporation, and John
E. Chapman (hereinafter called "Chapman").

                               PURPOSE AND INTENT

            This agreement (the "Agreement") is designed to recognize Chapman's
contribution to the Corporation(1) and encourage Chapman to remain in the
Corporation's employ by providing supplemental retirement benefits, keyed to a
specified percentage of his compensation, so that Chapman's percentage of
spendable retirement income will approximate the percentage of spendable
retirement income available to less compensated employees who also participate
in the Corporation's retirement plans. Due to restrictions presently imposed by
the Internal Revenue Code on benefits for highly compensated employees, the
percentage of spendable retirement income Chapman would receive under the
Corporation's current benefit plans relative to his current compensation would
be less than that of employees at lower salary levels. The benefits provided in
this Agreement are designed to be entirely supplemental to the Corporation's
other retirement benefits payable to Chapman; if Chapman receives the specified
percentage of compensation through pension plans and other benefits (as
described below) provided by the Corporation, no benefits will be paid out under
this Agreement. While any benefits are paid under this Agreement Chapman will be
available to consult for the Corporation. Further, these benefits are subject to
forfeiture if Chapman is terminated for Cause (as defined herein) or, as
described below, competes with the Corporation.

            Chapman has been employed by the Corporation since 1983, is now
serving SpecTran as its Senior Vice President-Technology and currently holds the
position of President of

Definitions".

SpecTran Communication Fiber Technologies, Inc., a wholly owned subsidiary of
SpecTran. The Board of Directors of SpecTran voted on May 8, 1996 to authorize
the Corporation to enter into this Agreement with Chapman.

CERTAIN DEFINITIONS(a) "Accrued Benefit" shall have the meaning set forth in
Section 2.01 of this Agreement.

(b) "Affiliate" shall mean any person or entity which controls, is controlled by
or is under common control with the Corporation. For the purpose of this
Agreement, control shall mean ownership of fifty percent (50%) or more of the
voting stock of any entity.

(c) "Benefit Computation Base" shall mean the average of Chapman's annual
compensation (defined as base salary, eligible bonus(2) and any salary reduction
amounts pursuant to Sections 

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

(2) To the extent that the average annual bonus paid to Chapman during the 36
month period in which the Benefit Computation Base is calculated is greater than
fifty percent (50%) of Chapman's average base salary over such period, the
excess bonus payments shall be considered ineligible for the purpose of
calculating the Benefit Computation Base. For example, assume that Chapman's
base salary and bonuses over the 36 month period are as shown in the following
two examples:

1.



                                    Base Salary        Bonus
                                    -----------        -----
                                                      
            Months 1-12             $200,000           $200,000

            Months 13-24            $210,000           $100,000

            Months 25-36            $220,000           $ 90,000

            Average                 $210,000           $130,000


            In this example, fifty percent (50%) of Chapman's average annual
base salary over the 36 month period is $105,000. Accordingly, of Chapman's
average annual bonus of $130,000 paid over that period, $25,000 will be deemed
ineligible for the purpose of calculating the Benefit Computation Base,
resulting in $105,000 of the average bonus being considered eligible.

2.



                                    Base Salary        Bonus
                                    -----------        -----
                                                      
            Months 1-12             $200,000                $200,000

            Months 13-24            $210,000                $ 10,000

            Months 25-36            $220,000                $ 30,000

            Average                 $210,000                $ 80,000


            In this example, fifty percent (50%) percent of Chapman's average
annual base salary over the 36 month period is $105,000. Chapman's average
annual bonus over that period of $80,000 is less than the average annual base
salary, and accordingly the entire average annual bonus will be eligible in
determining the Benefit Computation Base.

401(k) or 125 of the Code) paid during the thirty-six (36) consecutive calendar
months during Chapman's period of employment by the Corporation in which such
compensation is the highest.

this Agreement.

(e) The "Corporation" shall mean SpecTran, its successors and assigns, including
but not limited to any corporation, firm or person which is the survivor of a
merger or consolidation with SpecTran or which acquires substantially all of the
assets of SpecTran, and any of SpecTran's Affiliates.

1.01 EMPLOYMENT. The Corporation may employ Chapman in such capacity as the
Corporation may from time to time determine. Notwithstanding anything contained
herein, this Agreement is not an agreement of employment, a guaranty of
continuing employment or of employment in any particular position and nothing
herein shall restrict the Corporation concerning the terms and conditions of
Chapman's employment. The benefits provided by this Agreement are not part of
any salary reduction plan or an arrangement deferring a bonus or a salary
increase. Chapman has no option to take any current payment or bonus in lieu of
these salary continuation benefits.


                                   ARTICLE TWO


2.01 SUPPLEMENTAL RETIREMENT BENEFIT. Depending upon how many years Chapman has
been continuously in the employ of the Corporation, Chapman will be entitled to
a retirement benefit determined as of the effective date of his leaving the
Corporation's employment for whatever reason except Cause (as defined below),
including whether by (i) death, (ii) disability, (iii) termination of employment
or (iv) early retirement. The retirement benefit (also known as the "Accrued
Benefit") shall be an annual amount equal to Chapman's Benefit Computation Base
multiplied by the Annual Percentage Amount (as determined pursuant to Section
2.02, below). Chapman will receive a supplemental retirement benefit (the
"Supplemental Retirement Benefit") equal to (i) the amount of the Accrued
Benefit reduced by (ii) the sum of the benefits described in Subsections (1),
(2), (3) and (4) of Section 2.03, below (such benefits are referred to herein as
the "Offsetting Benefits"). The Supplemental Retirement Benefit, if any, to be
paid out under this Agreement, shall continue for fifteen (15) years, and be
paid in equal monthly installments commencing on the first day of the month
immediately following the later of Chapman's actual retirement or the Normal
Retirement Date (unless payment is accelerated in accordance with Sections 10.01
and 10.02 below). No 


                                     Page 4
   5
payment will be made under this Agreement if the Offsetting Benefits are equal
to or greater than the Accrued Benefit.

2.02 ANNUAL PERCENTAGE AMOUNT.

     (a)  The Annual Percentage Amount shall be determined (subject to
          subsection (b), below) by the number of years Chapman has been
          continuously employed by the Corporation as follows:

     (b)  Notwithstanding the provisions of Subsection (a) of this Section 2.02,
          in the event (a) Chapman does not remain employed by the Corporation
          for any reason during the twelve (12) month period following a Change
          in Control (as defined in Section 10.01, below) or (b) an event
          described in Section 10.01 occurs and either such other corporation,
          firm or person (as described in Section 10.01) does not agree that
          Chapman shall continue in the employ of the Corporation for any reason
          following such event or the Corporation's successor does not assume
          its obligations hereunder, Chapman will be deemed eligible to receive
          a Supplemental Retirement Benefit under this Agreement if at the time
          of the termination of his employment he will have completed at least
          five full years of service to the Corporation. In this case, the
          Annual Percentage Amount shall be determined by the number of years

     (c)  Anything else to the contrary in this Agreement notwithstanding, in
          the event of either (a) Chapman does not remain employed by the
          Corporation for any reason during the twelve month period following a
          Change in Control or (b) an event described in Section 10.01 occurs
          and either such other corporation, firm or person (as described in
          Section 10.01) does not agree that Chapman shall continue in the
          employ of the Corporation for any reason following such event or the
          Corporation's successor does not assume its obligations hereunder, and
          (c) in either case, the payment of the Supplementary Retirement
          Benefit 



                                     Page 7
   8
          hereunder is considered a Parachute Payment and when combined with all
          other payments considered to be Parachute Payments from the
          Corporation to Chapman due to the events described in (a) and (b)
          above, result in an Excess Parachute Payment, as defined by Section
          280G of the Internal Revenue Code of 1986, as amended, then the amount
          of the Supplementary Retirement Benefit shall be reduced so that the
          total Parachute Payments received by Chapman from the Corporation do
          not constitute an Excess Parachute Payment; provided, however, that
          this Section 2.02(c) shall not apply if the total Parachute Payments
          from the Corporation to Chapman due to the events described in (a) and
          (b) above exceed one hundred twenty percent (120%) of the amount of
          all Parachute Payments, not including any amount that would be
          considered an Excess Parachute Payment.

2.03 OFFSETTING BENEFITS.

     (a)  The following are the Offsetting Benefits, which reduce the Accrued
          Benefit for the purpose of calculating the Supplemental Retirement
          Benefit:

                    1. Fifty percent (50%) of Chapman's (actual or projected)
               annual primary social security retirement benefit projected as of
               Chapman's social security normal retirement age based on his
               Benefit Computation Base in effect on the date of termination of
               Chapman's employment with the Corporation;

                    2. The annual amount of benefits payable to Chapman (or his
               beneficiaries) at the Normal Retirement Date calculated on a
               single life annuity basis from any qualified defined benefit
               pension plan maintained and funded by the Corporation as of the
               date of this Agreement, or their successors, as such plan or
               plans may be amended or modified from time to time;



                                     Page 8
   9
                    3. The annual amount of benefits payable at the Normal
               Retirement Date on a single life annuity basis attributable to
               the portion of the account balances of Chapman arising from
               employer contributions (but excluding the portion of such
               balances arising from employee salary reduction and elective
               contributions) at the date of determination from the
               Corporation's 401(k) and other defined contribution retirement
               plans maintained by the Corporation as of the date of this
               Agreement, or their successors, as such plan or plans may be
               modified from time to time;

                    4. The annual amount of benefits payable to Chapman at the
               Normal Retirement Date calculated on a single life annuity basis
               from any other non-qualified supplemental retirement plan
               maintained and funded by the Corporation as of the date of this
               Agreement, or their successors, as such plan or plans may be
               amended or modified from time to time.

     (b)  The Corporation's obligation to pay the Offsetting Benefits shall not
          be affected by the termination of this Agreement and the Supplemental
          Retirement Benefit payable hereunder for any reason whatsoever.

     (c)  All calculations of the Supplemental Retirement Agreement payable to
          Chapman under this Agreement will be made assuming that Chapman
          participates in the Offsetting Benefits to the full extent permitted
          by law and the terms of those plans.

     (d)  If Chapman terminates his employment prior to his Normal Retirement
          Date, in calculating his Accrued Benefit, (i) the offset of primary
          social security retirement benefit shall be calculated on the basis of
          the amount projected to be payable at Chapman's social security normal
          retirement age assuming continued 


                                     Page 9
   10
          earnings by Chapman at the rate in effect at termination of employment
          until Chapman's social security normal retirement age; (ii) the offset
          for any qualified defined benefit plan shall be calculated on the
          basis of Chapman's accrued benefit in said plan upon termination of
          employment projected to be payable at Chapman's Normal Retirement
          Date; (iii) the offset for any benefits arising from employer
          contributions attributable to the account balances of Chapman arising
          from the Corporation's 401(k) plan or any other defined contribution
          retirement plan shall also be calculated on the basis of Chapman's
          accrued benefit in such plan(s) upon termination of employment
          projected to be payable at Chapman's Normal Retirement Date; and (iv)
          the offset for any non-qualified supplemental retirement plan shall be
          calculated on the basis of Chapman's accrued benefit in said plan upon
          termination of employment projected to be payable at Chapman's Normal
          Retirement Date.

2.04 OPTIONAL FORMS OF PAYMENT. In lieu of the fifteen (15) year certain
payments provided in Section 2.01 above, or whenever a Supplemental Retirement
Benefit is payable under Section 4.01 or 5.01 of this Agreement, Chapman may
elect by written notice to the Corporation in the calendar year prior to the
calendar year in which payments are to begin, an optional form of payment which
shall be the actual equivalent (factors defined in SpecTran's qualified defined
benefit pension plan) of the said fifteen (15) year certain payments. The
optional form of payment shall be any optional form of payment which is provided
to Chapman under the terms of SpecTran's qualified defined benefit pension plan.

2.05 VESTING. Anything to the contrary in this Agreement notwithstanding,
Chapman shall be entitled to one hundred percent (100%) of any benefit payable
under this Agreement under any one or more of Sections 2.01, 3.01, 4.01, 5.01,
10.01 or 10.02 at the date on which his entitlement to such benefit shall be
determined commencing with his original date of hire by 


                                    Page 10
   11
the Corporation, provided that such benefits are subject to forfeiture as
described in Sections 5.03 and 5.04, below.

                                  ARTICLE THREE

3.01 DEATH OF CHAPMAN.

     (a)  If Chapman dies while employed by the Corporation but prior to the
          commencement of the payment of the Supplemental Retirement Benefit
          under Section 2.01, 4.01 or 5.01, SpecTran will pay to the designated
          beneficiaries of Chapman, a total annual amount equal to the
          Supplemental Benefit earned by Chapman as of the date of death,
          payable over a period of fifteen (15) years certain commencing on the
          first day of the month next following the delivery to the Corporation
          of a death certificate and on a monthly basis thereafter. 

     (b)  If Chapman dies following the commencement of the payment of the
          Supplemental Retirement Benefit under Section 2.01, 4.01 or 5.01, such
          payments shall continue to the designated beneficiaries of Chapman
          until all of the Supplemental Retirement Benefit has been paid. 

     (c)  If Chapman dies following the termination of his employment with the
          Corporation and prior to the commencement of the payment of the
          Supplemental Retirement Benefit under Section 2.01, 4.01 or 5.01,
          SpecTran shall pay to Chapman's named beneficiaries an annual benefit
          which shall be Chapman's Supplemental Retirement Benefit as of the
          date of the termination of his employment. Such benefits shall be
          payable monthly, commencing on the first day of the month following
          the Normal Retirement Date, or any date prior to the Normal Retirement
          Date approved by the Corporation, and continuing for fifteen (15)
          years; provided, however, that Chapman's designated beneficiaries
          shall be entitled to accelerated payments of such benefits if and to
          the same extent Chapman would have been entitled to an accelerated
          payment of the Supplemental Retirement Benefit had he survived.

3.02 BENEFICIARIES. Chapman shall designate, in writing to the Corporation, on
the form titled "Designation of Beneficiary" attached hereto as Schedule A, one
or more beneficiaries. Chapman from time to time may change his designated
beneficiaries by delivering to the Corporation a dated, revised Designation of
Beneficiary form, revoking the prior designation. If no beneficiary is so named
or if no named beneficiary is living at the time a payment is due, benefit
payments shall be made, when due, to Chapman's estate. If payments of benefits
to a beneficiary commences and such beneficiary dies before all amounts to which
such beneficiary is entitled have been paid, the remaining benefits shall be
paid to the successive beneficiary or beneficiaries, if any, designated by
Chapman, or if none, to the beneficiary's estate.


                                  ARTICLE FOUR

4.01 DISABILITY PRIOR TO RETIREMENT. In the event Chapman shall become disabled,
mentally or physically, which disability prevents him from performing the
material aspects of his duties, the Corporation will pay no disability benefits
hereunder. Disability benefits (if any) will be paid to Chapman through such
insurance programs as may be sponsored by the Corporation. Upon the later of
termination of such other disability benefits (if any), or Chapman's attainment
of the Normal Retirement Date, Chapman shall commence receiving payment of his
Accrued Benefit determined as of the date of the disability. The Supplemental
Retirement Benefit shall be paid in equal monthly installments, for fifteen (15)
years certain commencing on the first day of the month following the later of
the termination of such benefits or the Normal Retirement Date, or in the manner
provided in Section 2.04.

4.02 RE-EMPLOYMENT FOLLOWING DISABILITY. In the event Chapman returns to work
with the Corporation after terminating employment because of disability, this
Agreement shall continue in full force and effect as though such disability had
not occurred. Under such circumstances, Chapman will receive credit towards
determining the Annual Percentage Amount for service prior to terminating his
employment because of disability and for service after resuming 


                                    Page 13
   14
employment with the Corporation, but will not receive credit for the interim
prior during which he was not employed by the Corporation.


                                  ARTICLE FIVE

5.01 EARLY RETIREMENT, TERMINATION OF SERVICE OR DISCHARGE. Except to the extent
otherwise provided in Sections 5.03 and 5.04, in the event that Chapman's
employment with the Corporation is terminated, voluntarily or involuntarily,
before Chapman attains the Normal Retirement Date, for reasons other than death
or disability, Chapman shall be entitled to a Supplemental Retirement Benefit,
determined as of the date of his termination of employment. Such benefit shall
be payable in equal monthly installments, commencing on the first day of the
month next following the later of the Normal Retirement Date or the date of
Chapman's actual retirement, and continuing for fifteen (15) years (except as
set forth in Sections 10.01 and 10.02); provided, however, that Chapman may
elect by execution and delivery to the Corporation of the form attached hereto
as Schedule B to have the monthly payments of the Supplemental Retirement
Benefit commence prior to the Normal Retirement Date at any date between age 60
and the Normal Retirement Date. Chapman understands that such election is being
made prospectively and is irrevocable. [add -election only applies to future
services]

5.02 OPTIONAL FORMS OF PAYMENT. In lieu of the fifteen (15) years certain
payments provided in Section 5.01, the Supplemental Retirement Benefit payable
under such Section may be payable in the manner provided in Section 2.04.

5.03 EMPLOYMENT BY COMPETITION. In the event that during the two year period
immediately following the termination of Chapman's employment for any reason,
Chapman shall compete with the business of the Corporation, then the
Supplemental Retirement Benefit which might otherwise be due and payable
hereunder shall be immediately forfeited and all rights of Chapman and his
beneficiaries hereunder shall become void; provided, however, that 


                                    Page 14
   15
if (a) Chapman does not remain employed by the Corporation for any reason during
the twelve (12) month period following a Change in Control or (b) an event
described in Section 10.01 occurs and either such other corporation, firm or
person (as described in Section 10.01) does not agree that Chapman shall
continue in the employ of the Corporation for any reason following such event or
the Corporation's successor does not assume its obligations hereunder, the
provisions of Section 5.03 shall not apply, but the provisions of Sections 10.01
and 10.02 shall govern. 

Chapman will be deemed to have competed with the business of the Corporation if,
during the two year period following termination of his employment with the
Corporation, he either (a) engages, directly or indirectly, or by stock interest
exceeding five percent (5%), or otherwise in any way, in any business in which
the Corporation was engaged during the term of his employment or which the
Corporation planned, during the term of his employment to enter, (b) solicits
any past, present or future customers of the Corporation in any way relating to
any business in which the Corporation was engaged during the term of his
employment, or which the Corporation planned during the term of his employment,
to enter, or (c) induces or actively attempt to influence any other employee or
consultant of the Corporation to terminate his or her employment or consultancy
with the Corporation.

5.04 FORFEITURE. Anything to the contrary in this Agreement notwithstanding
(other than Sections 10.01 and 10.02), the Supplemental Retirement Benefits
shall be immediately forfeited and all rights of Chapman and his beneficiaries
hereunder shall become null and void, if Chapman's employment with the
Corporation is terminated for Cause. For this purpose, a termination shall be a
termination for "Cause" only if the termination if for one or more of the
following: (i) the conviction of Chapman for committing any felony, (ii)
stealing from the Corporation, (iii) a willful breach by Chapman of a material
provision of this Agreement and (iv) if Chapman engages in gross misconduct,
such as fraud, dishonesty, gross negligence or insubordination. 



                                    Page 15
   16
If (a) Chapman does not remain employed by the Corporation for any reason within
one year following a Change in Control or (b) an event described in Section
10.01 occurs and either such other corporation, firm or person (as described in
Section 10.01) does not agree that Chapman shall continue in the employ of the
Corporation for any reason following such event or the Corporation's successor
does not agree to assume its obligation hereunder, the provisions of this
Section 5.04 shall not apply, but the provisions of Sections 10.01 and 10.02
shall govern.

5.05 AVAILABILITY TO CONSULT. For so long as Chapman is receiving benefits
pursuant to this Agreement, Chapman will keep himself available to consult with,
and respond to inquiries from, the Corporation relating to its business affairs,
at reasonable time(s) and to reasonable extent.


                                   ARTICLE SIX

6.01 INTEREST. Any payment that is required to be made hereunder that is delayed
beyond the date specified in this Agreement shall bear interest at a variable
rate which shall be the rate of interest on one year U.S. Treasury Bills
determined at the first auction of each calendar year or part thereof during the
period of which interest is to be applied to any obligation hereunder.


                                  ARTICLE SEVEN

7.01 ALIENABILITY. Neither Chapman, nor any beneficiary under this Agreement
shall have any power or right to transfer, assign, anticipate, hypothecate,
mortgage, commute, modify, or otherwise encumber in advance any of the benefits
payable hereunder, and any attempt to do so shall be deemed null and void. The
seizure of the benefits payable hereunder for the payment of any debts,
judgments, alimony or separate maintenance, owed by Chapman or his beneficiary
or any of them, or the transfer of such benefit by operation of law in the event
of 


                                    Page 16
   17
bankruptcy, or otherwise, shall be deemed to be a transfer prohibited by this
Agreement, and will result in the immediate termination of all benefits payable
hereunder.

                                  ARTICLE EIGHT

8.01 PARTICIPATION IN OTHER PLANS. Nothing contained in this Agreement shall be
construed to alter, abridge, or in any manner affect the rights and privileges
of Chapman to participate in and be covered by any pension, profit sharing,
group insurance, bonus or any other employee plan or plans which the Corporation
may have or hereafter have.


                                  ARTICLE NINE

9.01 FUNDING.

     (a)  The Corporation reserves the right at its sole and exclusive
          discretion to insure or otherwise provide for the obligations of the
          Corporation undertaken by this Agreement or to refrain from same, and
          to determine the extent, nature and method thereof, including the
          establishment of one or more trusts. Should the Corporation elect to
          insure this Agreement, in whole or in part, through the medium of
          insurance or annuities, or both, the Corporation shall be the owner
          and beneficiary of the policy or annuity. At no time shall Chapman be
          deemed to have any right, title or interest in or to any specified
          asset or assets of the Corporation, or any trust or escrow
          arrangement, including, but not by way of restriction, any insurance
          or annuity contracts or the proceeds therefrom.

     (b)  Any such policy, contract or asset shall not in any way be considered
          to be security for the performance of the obligations of this
          Agreement.

     (c)  If the Corporation purchases a life insurance or annuity policy on the
          life of Chapman, Chapman agrees to sign any papers that may be
          required for that purpose and to undergo any medical examination or
          tests (at the Corporation's expense) which may be necessary, and
          generally cooperate with the Corporation in securing such policy.



                                    Page 17
   18
     (d)  To the extent Chapman acquires a right to receive benefits under this
          Agreement, such right shall be equivalent to the right of an unsecured
          general creditor of the Corporation.


                                   ARTICLE TEN

10.01 REORGANIZATION. SpecTran shall not merge or consolidate into or with
another corporation if such merger or consolidation shall result in the other
corporation being the survivor corporation, nor shall it sell substantially all
of its assets to another corporation, firm or person, unless and until Chapman
and such other corporation, firm or person agree that Chapman shall continue in
the employ of the succeeding, continuing or acquiring corporation, firm or
person and such other corporation, firm or person agrees in writing without
further qualification to assume and discharge the obligations of SpecTran under
this Agreement. If Chapman and such corporation, firm or person do not agree
that Chapman shall continue in the employ of such corporation, firm or person,
or such corporation, firm or person does not so agree to assume and discharge
such obligations, SpecTran shall pay to Chapman, in one lump sum, his
Supplemental Retirement Benefit as of the date of such merger, consolidation or
sale. All calculations of the Supplemental Retirement Benefit, for purposes of
this Section 10.01, shall be discounted to present value in accordance with the
actuarial tables used in SpecTran's defined benefit pension plan.

For the purpose of clarification, any transaction between SpecTran and any of
its Affiliates is not intended to be covered by this Section 10.01.

10.02 CHANGE IN CONTROL. In the event that a Change in Control occurs prior to
the Normal Retirement Date and either (a) Chapman is dismissed without Cause
from employment by the Corporation up to and including




                                    Page 18
   19
twelve (12) months from such Change in Control or (b) Chapman voluntarily leaves
the employ of the Corporation up to and including twelve (12) months from such
Change in Control, then in either case SpecTran shall pay to Chapman, in one
lump sum, his Supplemental Retirement Benefit as of the date of the termination
of Chapman's employment. All calculations of the Supplemental Retirement
Benefit, for purposes of this Section 10.02, shall be discounted to present
value in accordance with the actuarial tables used in SpecTran's defined benefit
pension plan. For the purposes of this Agreement, "Change in Control" shall mean
(a) the date of public announcement that a person has become, without the
approval of SpecTran's Board of Directors, the beneficial owner of 20% or more
of the voting power of all securities of SpecTran then outstanding; (b) the date
of the commencement of a tender offer or tender exchange by any person, without
the approval of SpecTran's Board of Directors, if upon the consummation thereof
such person would be the beneficial owner of 20% or more of the voting power of
all securities of SpecTran then outstanding; or (c) the date on which
individuals who constituted the Board of Directors of SpecTran on the date this
Agreement was adopted cease for any reason to constitute a majority thereof,
provided that any person becoming a director subsequent to such date whose
election or nomination was approved by at least three quarters of such incumbent
Board of Directors shall be considered as though such person were an incumbent
director.

person feels entitled to receive them, a claim shall be made in writing to the
Corporation within sixty (60) days after written notice from the Corporation to
Chapman or his beneficiary or personal representative that payments are not
