Act")), to acquire, by purchase, offer to purchase, merger or otherwise, any

for any other person in connection with any of the foregoing.

     3. GCC'S REPRESENTATIONS. GCC represents and warrants to SpecTran that, as
of the date hereof, neither it nor any of its Affiliates is the beneficial owner
of any SpecTran Securities nor, to its knowledge, does any of its or their
respective directors or officers beneficially own any SpecTran Securities. GCC
further represents and warrants to SpecTran that (a) the execution, delivery and
performance of this Agreement by it has been duly authorized by all necessary
corporate action on its part, and (b) this Agreement has been duly and validly
executed and delivered by GCC, and assuming this Agreement constitutes the valid
and binding agreement of SpecTran, constitutes the valid and binding agreement
of GCC, enforceable against it in accordance with its terms, subject as to
enforceability to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting creditors' rights and to general
principles of equity.

     4. PERMITTED TRANSACTIONS. Notwithstanding anything in this Agreement to
the contrary, nothing herein is intended to preclude (a) GCC from acquiring (i)
a person or entity that owns SpecTran Securities provided GCC disposes of such
SpecTran Securities as soon thereafter as is commercially practicable or (ii)
APD's Interest in General Photonics LLC pursuant to Article 10 of the LLC
Agreement or (b) any director or officer of GCC or any of its Affiliates from
acquiring, directly or indirectly, up to one percent (1%) of any class of
SpecTran Securities then issued and outstanding.

hereof and shall remain in full force and effect until the earlier to occur of

thereof that was initiated by a proposal by any of the Class A Managers that
results in a termination of the LLC Agreement.

     6. REMEDIES FOR BREACH. GCC agrees that irreparable damage would occur in
the event of a Material Breach. Accordingly, GCC agrees that SpecTran shall be
entitled to an injunction or injunctions to prevent Material Breaches of this
Agreement and to enforce specifically the terms and provisions hereof, this
being in addition to any other remedy which it may be entitled at law or equity.

     7. CHANGES: WAIVERS. This Agreement may not be changed in any manner except
by a written agreement signed by both parties. The failure of either party to
enforce at any time any of the provisions of this Agreement shall in no way be
construed to be a waiver of any such provision, nor in any way affect the
validity of this Agreement or any part thereof or the right of either party
thereafter to enforce each and every such provision. No waiver of any breach of
this Agreement shall be held to be a waiver of any other or subsequent breach.

counterparts each of which shall be deemed to be an original, but all of such
counterparts together shall be deemed to be one and the same instrument.
