Territory, and that for the duration of this Agreement, they will not compete

products in the Territory except as provided in the Operative Agreements. In
support of this objective, the Members, GCC and SpecTran will not, and will
cause their Affiliates to not, compete with the Business of the JV Company in
the Territory.

     3. TERM. The term of this Non-Competition Agreement will be for so long
as GCI (or an Affiliate thereof) and APD (or an Affiliate thereof) both have an
ownership interest in the JV Company and thereafter, with regard to a party no
longer having an

   4





ownership interest in the JV Company and that party's Affiliates, for a period
of eighteen (18) months after the date that such party (or Affiliates thereof)
ceases to have an ownership interest in the JV Company (for ease of reference,
this portion of the term of the Non-Competition Agreement may be referred to as
"The Eighteen Month Period"). Notwithstanding the foregoing, this
Non-Competition Agreement will terminate if the Members voluntarily agree to
dissolve the JV Company. In addition, if either Member or one of its Affiliates
that is a party to an Operative Agreement commits a Material Breach of any of
the Operative Agreements not remedied during any applicable cure period, then
this Non-Competition Agreement will terminate as to the other Member and its
Affiliates, so long as none of them has also committed a Material Breach of any
of the Operative Agreements.

     4. NON-COMPETITION AND NON-SOLICITATION. Subject to Sections 5 and 7 below,
the parties agree that during the term of this Agreement, each shall not, and
shall not permit any of its Affiliates, for its own account, as a general
partner, joint venturer, consultant, stockholder or otherwise, alone or in
association with any other Person (i) to engage in any activity that would be
competitive with the Business in the Territory, including but not limited to [A]
solicitation of the JV Company's customers, suppliers, partners, joint
venturers, agents, distributors, licensors, or licensees with the intention of
competing with the Business, [B] permitting its name or any part thereof to be
used or employed anywhere in the world in connection with any enterprise which
is or would be competing with the Business in the Territory and [C] knowingly
arranging for or permitting products manufactured outside the Territory which
would be competitive with the JV Company's Products to be shipped, distributed
or sold in the Territory; or (ii) to knowingly solicit, induce or actively
attempt to influence any employee or consultant to terminate his or her
employment or consultancy with the JV Company, except to the extent that APD may
replace the Chief Executive Officer and GCI may replace the Chief Financial
Officer as provided in the Limited Liability Company Agreement.

     5. CERTAIN PERMITTED ACTIVITIES. Notwithstanding Section 4 hereof, with
regard to investments and acquisitions, the parties agree as follows:

          (a) The General Cable Group and SpecTran and its Affiliates may
acquire an interest in a Direct Competitor of the JV Company of no greater than
five (5) percent of the voting stock (all references to stock, if an entity does
not have stock, shall be deemed to be references to voting power) of such
entity. GCC will cause all Affiliates of GCC and GCI, other than the General
Cable Group, to not acquire any interest in a Direct Competitor of the JV
Company other than up to a maximum of ten (10) percent of the voting stock of
such entity. A party holding less than the maximum permitted interest may at any
time, including the Eighteen


                                        4





   5





Month Period, increase such interest up to such maximum. In both of these
exceptions described in the first two sentences of this Section 5(a), all
interests acquired in the voting stock of a Direct Competitor shall be for
investment only and not with an intent to operate, control the operations of or
participate in management decisions of a Direct Competitor. Furthermore,
confidential or non-public information about a Direct Competitor in which an
interest is being or has been acquired as described above in this Section 5(a)
shall not (i) in the case where SpecTran or the General Cable Group is the
acquiror, be disclosed to the acquiring company or its Affiliates and (ii) in
the case where any Affiliate of GCC or GCI, other than the General Cable Group,
is the acquiror, be disclosed to the General Cable Group. Notwithstanding the
foregoing, it is understood and agreed that SpecTran and the General Cable Group
may acquire control of a corporation or other entity which in turn has an
interest in a Director Competitor of more than five (5) percent and the
Affiliates of GCC and GCI other than the General Cable Group may acquire control
of a corporation or other entity which in turn has an interest in a Direct
Competitor of more than ten (10) percent, provided that in any such case, the
acquirer will cause its acquired company to divest itself of its interest in
such Direct Competitor as soon as commercially practicable, but in no event more
than three months after the acquisition thereof or such longer period as may be
required by law.

          (b) (i) Each of GCI (including its Affiliates) and SpecTran (including
its Affiliates) may acquire Control of one company which has a business that
competes with the Business in the Territory (a "Competing Business") but is not
a Direct Competitor, provided that the acquiring company puts the Competing
Business to the JV Company. The acquiror, will notify the JV Company of its
intent to acquire a Competing Business as soon as practical after the acquiror
commences material discussions with the owners of the Competing Business,
subject to any restriction on such disclosure required by applicable laws and
subject to the JV Company executing and delivering to the acquiror a
confidentiality agreement identical in form and substance to that executed by
the acquiror (or if none, a standard and customary confidentiality agreement).
The acquiror shall deliver written notification to the JV Company of its
acquisition of a Competing Business within two business days after the closing
thereof, and the JV Company shall be obligated to purchase the Competing
Business at its appraised value by paying


[FN]
- -----------
    (1) The appraised value shall be the fair market value of the Competing
Business (the "Fair Value"). Unless otherwise agreed, promptly after the
delivery of the notice, the acquiror and the JV Company will each obtain an
independent valuation of the Competing Business from an investment banking,
accounting or other similarly qualified firm ("Appraiser") and will exchange
their valuation


                                       5

the acquiror at least [********************] of the appraised value in cash. The
acquiror will finance the remainder of the purchase price for up to [**********]
(as determined by the JV Company) at an interest rate [****************] at 
which the JV Company could otherwise have borrowed to finance the acquisition
(after taking into account the debt it would be assuming to finance this
purchase) and such financing will be secured by a first priority lien on the
assets being put to the JV Company. The JV Company will be obligated to
refinance such financing as soon as practicable. An appropriate asset or stock
purchase agreement, including normal representations and warranties regarding
the Competing Business (which will be substantially identical to those the
acquiror obtained from the seller of the Competing Business), will be
negotiated in good faith between the acquiror and the JV Company. Regarding any
decisions or actions required by the JV Company in this regard, the vote of the
Managers who do not represent the acquiror will be determinative.

              (ii) If each of GCI (including its Affiliates) or SpecTran
(including its Affiliates) wishes to acquire Control of a second company which
has a Competing Business but is not a Direct Competitor, GCI or SpecTran, as the
case may be, shall first obtain the prior Super-majority Approval of the JV
Company's Board, which approval, if not forthcoming within thirty (30) days of
notice thereof, will be deemed withheld.

              (iii) During The Eighteen Month Period, the parties remaining
bound by this Non-Competition Agreement (or any successor thereto), and their
Affiliates may not acquire Control of a company which has a Competing Business,
whether or not it is a Direct Competitor.

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

reports with each other. If the two valuation reports do not differ by more than
five (5) percent, then the Fair Value will be the average of the two valuations.
If the two valuations differ by more than five (5%) percent, then the two firms
which provided the reports will, within thirty (30) days after the exchange of
reports, select a third Appraiser (familiar with the industry but with
absolutely no connection or business relationship with the JV Company, the
Members or their Affiliates) to review the valuations of the two Appraisers and
select the one that best represents Fair Value. The third Appraiser will notify
the JV Company and the acquiror which one of the reports it has selected as
representing Fair Value within thirty (30) days of such Appraiser's appointment.
The JV Company will pay the expenses of the third Appraiser. closing of the
purchase of the Competing Business will take place within ten (10) days of the
final determination of Fair Value unless a later closing is required in order to
comply with any legal, regulatory or stock exchange requirements.

          (c) During the Eighteen Month Period, GCI, GCC and SpecTran may not,
and will cause their respective Affiliates to not, acquire a non-Controlling
interest in a company which is not a Direct Competitor, unless (i) the
investment is held at the time the JV Company terminates through the Buy/Sell
process described in the Limited Liability Company Agreement, provided the owner
does not increase its interest (e.g., its stock ownership or rights to elect
directors) during the term of such Eighteen Month Period, and (ii) the owner
takes steps so that its Affiliates do not provide support with respect to the
investment any greater than provided before the beginning of The Eighteen Month
Period. The parties acknowledge that during The Eighteen Month Period, the
parties remaining bound by this Non-Competition Agreement (or any successor
thereto) and their Affiliates shall not increase their interest (e.g., its stock
ownership or similar evidence of ownership or rights to elect directors or other
governing officials) in a company which is not a Direct Competitor in which it
holds a non-Controlling interest or take any new interest in another company
which is not a Direct Competitor.

          (d) GCI, GCC and SpecTran may not, and shall cause their respective
Affiliates to not, acquire Control of any company located outside the Territory
which has a Competing Business that exports competing products into the
Territory, unless either (i) that company ceases such exports to the Territory
upon the completion of the acquisition or during an unwinding transitional
period during which time existing contractual obligations and accepted orders
are fulfilled, but no new contracts are entered into or new orders are accepted,
or (ii) the acquiring company puts the Competing Business to JV Company as its
one permitted put as set forth in Section 5(b)(i) above.

     6. EFFECT OF AGREEMENT ON NEW AFFILIATES. During the term of this
Non-Competition Agreement, if an entity that is not an Affiliate of a party
hereto as of the date of the execution hereof subsequently becomes an Affiliate,
then the provisions relating to Affiliates will apply to such entity; provided,
however, that nothing herein is intended to prevent any Person which has an
existing business that is competitive with the JV Company from continuing such
business in the event such Person acquires any party or an Affiliate thereof
which is subject to this Non-Competition Agreement. During the term of this
Non-Competition Agreement, if an Affiliate of a party ceases to be an Affiliate,
then the provisions hereof relating to Affiliates will cease to apply to such
entity.

     7. CERTAIN EXCEPTIONS. Notwithstanding anything in this Non-Competition
Agreement to the contrary:

          (a) the parties agree that from and after an assignment of any
Interest in the JV Company pursuant to Article 10 of the LLC Agreement, the
activities contemplated by Section 6 of the Fiber


                                       7





   8


Supply Agreement and Section 7 of the Product Purchase Agreement shall not be
deemed a violation of this Non-Competition Agreement; and

          (b) SpecTran's Affiliate, SpecTran Specialty Optics Company ("SSOC"),
may manufacture and market (i) OEM-specified/proprietary and/or branded optical
fiber cables or connectorized optical fiber cable assemblies used to
interconnect those OEM's components, subsystems or systems (provided, however,
that SSOC will not compete with the JV Company with respect to the private label
business for standard open architecture customer premise systems currently
conducted by APD), (ii) optical fiber cables used to monitor or control
manufacturing equipment or processes and (iii) certain projects (e.g., New York
Transit Authority) in accordance with guidelines established by Super-majority
Approval of the Managers of the JV Company.

     8. REPRESENTATIONS AND WARRANTIES. Each of SpecTran and APD, on the one
hand, and GCC and GCI, on the other hand, represent and warrant that neither
they nor any of their respective Affiliates currently have an interest in any
Person where a super-majority vote is required to confer ownership or the power
to vote voting stock or other evidence of ownership or to elect or control the
vote of the majority of the board of directors or other governing body of such
Person, other than the interest of one of GCC and GCI's Affiliates in Qindago
York Transportation Co., Ltd.

     9. SEVERABILITY. In the event that the restrictions on competition set
forth herein shall be determined by a court of competent jurisdiction to be
unenforceable or invalid in any respect, including by reason of its extent,
duration or geographic scope, such restrictions shall remain and be interpreted
as valid and enforceable to the maximum extent permitted by applicable law,
which maximum extent, duration and geographic scope shall be interpreted and
determined by such court in such action.

     10. EQUITABLE REMEDIES. The parties hereto, on behalf of themselves and
their respective Affiliates, each agrees and acknowledges that all restrictions
contained in this Agreement are necessary and fundamental to the protection of
the Business and the goodwill attributable thereto and that a breach by any of
the parties or any of their respective Affiliates of any covenant or provision
in this Agreement would result in immediate and irreparable damage to the JV
Company that could not adequately be compensated for by monetary award.
Accordingly, it is expressly agreed by each of GCC, GCI, SpecTran and APD, that,
in addition to all other remedies available to them, the non-breaching parties
and the JV Company shall be entitled to the immediate remedy of a restraining
order, interim injunction or other form of injunctive relief as may be decreed
or issued by any court of competent jurisdiction to restrain or enjoin the
breaching party from breaching or threatening to breach any such covenant or
provision,


                                        8





   9





and the breaching party will not raise as a defense that the non-breaching
parties or the JV Company have an adequate remedy at law.

     11. ENTIRE AGREEMENT. This Agreement (together with applicable provisions
of the other Operative Agreements referenced herein) constitutes the entire
understanding and agreement of the parties with respect to the subject matter
hereof. All previous agreements, promises, representations, commitments and
understandings, whether verbal or written, between the parties regarding the
subject matter hereof are merged into and superseded by this Agreement. This
Agreement shall be binding upon and inure to the benefit of and be enforceable
by the respective legal representatives, successors and permitted assigns of the
parties hereto. Nothing contained in this Agreement, express or implied, is
intended to confer upon any person or entity other than the parties hereto and
their respective successors and permitted assigns any rights or remedies under
or by reason of this Agreement.

     12. AMENDMENT. This Agreement may be amended or modified only by a written
agreement signed by each of the parties hereto.

     13. WAIVER. No waiver by any party of any default or breach of any term,
condition or covenant of this Agreement shall be deemed to be a waiver of any
subsequent default or breach of the same or any other term, condition or
covenant contained herein, nor shall it be effective unless in writing and
signed by the party to be charged therewith. The failure of any party hereto to
enforce at any time or for any period of time any provision hereof in accordance
with its terms shall not be construed to be a waiver of such provision or of the
right of such party thereafter to enforce any provision hereof.

     14. ASSIGNMENT. This Agreement may not be assigned by any party hereto
without the prior written consent of the other party hereto, provided, however,
that the parties agree that APD and GCI may assign their rights and obligations
under this Agreement to any permitted transferee of an Interest in the JV
Company as provided in the Limited Liability Company Agreement.

     15. NOTICES. All notices, consents, waivers or other communications which
are required or permitted hereunder shall be in writing and shall be sufficient
if delivered personally (including by means of recognized courier service for
which a written receipt is given) or by registered or certified mail, return
receipt requested, postage prepaid, or by facsimile transmission providing a

Dear John,

Thank you for your June 28, 1996 letter dated October 17, 1996 requesting
additional multimode fiber purchase amounts pursuant to Section 1.1 of our
Supply Agreement. As we discussed, SpecTran confirms that it will supply to
Corning, and Corning confirms that it will purchase from SpecTran, [******]
kilometers of multimode fiber [**********************************************
***************]. As a result, [**********************************************
******************************************************************************
**************************] under our Supply Agreement.

Should additional amounts of multimode fiber become available for sale to
Corning in [****], SpecTran agrees to notify Corning of such availability as 
soon as practical. Your request [******************************************] in 
the third paragraph of your October 17, 1996 letter is too restrictive and we 
are not able to add it to our Agreement.

Also pursuant to Section 1.1 of our Supply Agreement, SpecTran commits to supply
to Corning and Corning commits to purchase from SpecTran [********************
************************]. On or before [*******************] SpecTran agrees to
notify Corning [***************************************************************
*************************************************].

These additional commitments by Corning and SpecTran increase the minimum amount
of multimode fiber to be purchased by Corning and supplied by SpecTran under our
Supply Agreement from [****************************************]. All other
terms and conditions of our Supply Agreement will remain unchanged.

Please acknowledge your agreement to the terms detailed in this letter by
signing below, faxing the signed letter back to me by Monday, November 11th, to
be followed by one original copy as soon as possible. Please feel free to call
me at (508) 347-8534 if you have any questions.



Sincerely yours,

/s/ Edward T. Connor
