         their sole discretion, withdraw the aforesaid permissions to assign,
         sell, transfer or otherwise dispose of Inventory upon the occurrence
         and continuance of any Event of Default.

         forth on Annex 1 until such time as any Obligor shall be permitted to

                  in respect of such insurance on the Closing Date shall be

         with, the security interests hereby granted to the Trustee by the
         Obligors under or in respect of any of the Collateral by reason of

                           (i) the failure by any of the Obligors to perform any
                  alleged obligations or undertakings required to be performed

                  the Trustee nor the exercise of, or failure to exercise, any
                  right, power or remedy in this Agreement conferred upon the
                  Trustee shall be deemed or construed to obligate the Trustee
                  or any holder of Secured Obligations to pay any sum of money,
                  take any other action or incur any liability in connection
                  with, or collect or realize upon, any of the Collateral. It is

                  Trustee and the Beneficiaries shall not be liable in any way

                  disposal thereof shall be borne and paid by the Obligors.

                           (ii) If any of the Obligors shall fail to pay any of
                  the aforesaid expenses and taxes, the Trustee may, at the
                  instruction of the Majority Beneficiaries and at such
                  Obligor's expense, pay the same, and any such payment shall be
                  deemed an advance by the Trustee to such Obligor payable on
                  demand together with

                  interest at the highest rate then payable on any of the
                  Secured Obligations. If any of the Obligors shall fail to
                  perform any of its other undertakings or agreements or
                  obligations under this Agreement, the Trustee may (but shall
                  not be required to) itself perform, or cause performance of,
                  such undertaking, agreement or obligation, and the expenses of
                  the Trustee incurred in connection therewith shall be payable
                  by such Obligor on demand together with interest at the
                  highest rate then payable on any of the Secured Obligations
                  and shall otherwise be treated as a Secured Obligation
                  hereunder.

                           (iii) If, by reason of any suit or proceeding of any
                  kind, nature or description against any of the Obligors, or by
                  any Obligor or any other party against any other Person, which
                  in the Trustee's sole discretion makes it advisable for the
                  Trustee to seek counsel for the protection and preservation of
                  the Collateral, or to defend its own interest or the interests
                  of the Beneficiaries, such out-of-pocket expenses and
                  reasonable counsel fees shall be allowed to the Trustee and
                  borne and paid by such Obligor.

                  (L) NO LIABILITY FOR SAFEKEEPING. Except to the extent
         specifically limited by applicable law, the Trustee shall not be liable
         or responsible in any way for the safekeeping of the Collateral or for
         any loss or damage thereto or for any diminution in the value thereof,
         or any act or default of any warehouseman, carrier, forwarding agency
         or other Person, but the same shall be at the sole risk of the Obligor
         owning such Collateral.

                  (M) NO VIOLATION OF LAW. No Obligor shall

                           (i) violate any law, ordinance or governmental rule
                  or regulation (including, without limitation, any
                  Environmental Protection Laws) to which it or the Collateral
                  is subject, nor

                           (ii) fail to obtain any license, permit, franchise or
                  other governmental authorization necessary to the ownership of
                  the Collateral, the sale or lease of the Inventory, the
                  collection of the Accounts, or the operation of the Equipment,

         which violation or failure to obtain might have a Material Adverse
         Effect.

                  (N) FURTHER ASSIGNMENTS; MARKING OF COLLATERAL. Each of the
         Obligors shall deliver to the Trustee, at such times and in such form
         as may be reasonably designated by the Trustee or the Majority
         Beneficiaries from time to time, assignments, reports and schedules
         relating to the Collateral. Upon request by the Trustee or the Majority
         Beneficiaries, each of the Obligors shall mark its books and records to
         reflect the security interests of the Trustee in the Collateral.

                  (O) PERMITS AND WARRANTIES. To further protect the security
         afforded by this Agreement with respect to the Permits and Warranties,
         each Obligor agrees:

                           (i) to faithfully abide by, perform and discharge in

                  otherwise change or terminate any of the Permits and
                  Warranties, or waive any provision thereof in any manner that
                  would materially affect the security interest of the Trustee
                  in the Permits and Warranties, without the written consent of
                  the Trustee and the Majority Beneficiaries, except to the
                  extent that such actions would not, individually or in the
                  aggregate, have a Material Adverse Effect; and

                           (iii) to appear in and defend any action or
                  proceeding to the extent deemed necessary in its reasonable
                  business judgment arising under, growing out of or in any
                  manner connected with the obligations, covenants, conditions,
                  duties, agreements or liabilities of such Obligor under any of
                  the Permits and Warranties, at the sole cost and expense of
                  such Obligor.

5.       DEFAULTS -- REMEDIES

         5.1 DEFAULT REMEDIES.

                  (A) GENERAL. If an Event of Default exists, the Trustee may

                           (i) exercise all of the rights and remedies conferred
                  in this Agreement, in the Trust Indenture and in the other
                  Lending Documents, and

                           (ii) exercise all of the rights and remedies of a
                  secured party under the Code and all of the rights and
                  remedies in this Agreement or otherwise available at law or in
                  equity.

                  (B) RIGHTS AND REMEDIES.

                           (I) PAYMENTS TO LOCKBOX. If an Event of Default
                  exists, the Trustee may require the Obligors to instruct the
                  Account Debtors to make payment thereof directly to the
                  Trustee or to a Person or lockbox so designated by the
                  Trustee. If an Event of Default shall exist and any Obligor
                  receives any cash, checks, drafts, money orders or other
                  instruments in payment of any Accounts, it shall hold the same
                  in trust for the Trustee and shall segregate the same and
                  shall promptly deliver the same (in the identical form as
                  received) to the Trustee or to such Person or lockbox as the
                  Trustee may designate.

                           (II) NOTIFICATION OF DEBTORS. If an Event of Default
                  shall exist, each of the Obligors authorizes the Trustee (but
                  the Trustee shall not be obligated) to communicate with any
                  Account Debtor or any other Person primarily or secondarily
                  liable under an Account with regard to any delinquent payment
                  or other payment status of such Account or any matter relating
                  thereto or with regard to the verification that such Account
                  Debtor did incur the obligations thereunder and the terms and
                  provisions thereof. If an Event of Default exists, each of the
                  Obligors agrees, upon the request of the Trustee, to notify
                  each Account Debtor in writing of the assignment to the
                  Trustee of its respective Account, the Trustee's security
                  interest therein and any other matter relating thereto.
                  Notwithstanding the immediately preceding sentence, the
                  Trustee shall, during the existence of any Event of Default,
                  have the right, without first making a request of the Obligor
                  owning such Accounts, to notify each Account Debtor of the
                  assignment to the Trustee of its respective Account, the
                  Trustee's security interest therein and any other matter
                  relating thereto.

                  (C) COLLECTION. The Trustee may, at any time and from time to
         time during the existence of any Event of Default, demand, sue for,
         collect or receive any money or Property at any time payable or
         receivable on account of or in exchange for, or make any compromise or
         settlement reasonably deemed desirable by the Trustee with respect to,
         any Account, and/or extend the time of payment, arrange for payment in
         installments, or otherwise modify the terms of, or release, any Account
         or any collateral, guaranty or insurance therefor or in respect
         thereof, all without notice to or consent by the Obligors and without
         otherwise discharging or affecting the Secured Obligations, the other
         Collateral or the security interest granted herein. Without limiting
         any of the foregoing,

SPECTRAN CORPORATION               20               SECURITY AGREEMENT
   25
                                                         5. DEFAULTS -- REMEDIES

         each of the Obligors hereby authorizes the Trustee and any agent or
         designee thereof during the existence of any Event of Default to take
         any and all steps in the name of such Obligor, necessary or desirable,
         in the determination of the Trustee or the Majority Beneficiaries, to
         collect all amounts due under any and all Accounts, including, without
         limitation, endorsing such Obligor's name on checks and other
         instruments representing collections and/or proceeds of Accounts and
         enforcing such Accounts.

                  (d) POSSESSION OF COLLATERAL; ENTRY OF PREMISES. If an Event
         of Default exists, the Trustee shall have the right, at any time or
         from time to time, to take immediate possession of any or all
         Collateral that is tangible personal Property, and may require each of
         the Obligors to assemble such Collateral, at the expense of each such
         Obligor, and to make it available to the Trustee at a place to be
         designated by the Trustee that is reasonably convenient to both
         parties, and may enter any of the premises of each of the Obligors (or
         wherever such Collateral shall be located) without force and with or
         without process of law, and keep and store the same on such premises
         until sold (and if such premises be the Property of any Obligor, such
         Obligor agrees not to charge the Trustee for storage thereof for a
         period of at least ninety (90) days after sale or disposition of such
         Collateral).

                  (e) BOOKS AND RECORDS. At the request of the Trustee at any
         time while an Event of Default exists, each of the Obligors shall
         assemble all of the Books and Records which evidence the Collateral and
         make the same available to the Trustee or its designee at a place
         selected by the Trustee or its designee.

                  (f) SALE OF COLLATERAL; COMMERCIAL REASONABLENESS. Each of the
         Obligors and the Trustee agree that ten (10) days notice to such
         Obligor of any public or private sale or other disposition of the
         Collateral shall be reasonable notice thereof, and such sale shall be
         at such reasonable location as the Trustee shall designate in such
         notice. Any other requirement of notice, demand or advertisement for
         sale is, to the extent permitted by law, waived by each of the
         Obligors. Sales for cash, or on credit to a wholesaler, retailer or
         user of the Collateral, at any public or private sale are all hereby
         deemed (without limitation) to be commercially reasonable (as defined
         in the Uniform Commercial Code as in effect in any applicable
         jurisdiction). The Collateral may be sold at any private or public sale
         in one or more lots. The Trustee shall have, to the extent permitted by
         applicable law, the right to bid at any such public sale on behalf of
         any one or more Beneficiaries (who shall also have the right to bid
         individually).

                  (g) CERTAIN OFFSET RIGHTS IN RESPECT OF COLLATERAL. If an
         Event of Default exists, the Trustee may also, with or without
         proceeding with sale or foreclosure or demanding payment of the Secured
         Obligations, without notice, appropriate and apply to the payment of
         the Secured Obligations and the other obligations secured under this
         Agreement any and all Collateral in its possession (including, without
         limitation, any and all balances, credits, deposits, accounts,
         reserves, or other moneys due or owing to any of the Obligors held by
         the Trustee hereunder or otherwise) in accordance with the provisions
         of the Trust Indenture.

                  (h) UNDERTAKINGS CUMULATIVE. All covenants, conditions,
         provisions, warranties, guaranties, indemnities and other undertakings
         of the Obligors contained in this Agreement or any other Lending
         Document, or in any document referred to in this

         Agreement or any other Lending Document or contained in any agreement
         supplementary to this Agreement or any other Lending Document, shall be
         deemed cumulative to and not in derogation or substitution of any of
         the terms, covenants, conditions or agreements of the Obligors
         contained in this Agreement or any other Lending Document.

                  (i) PAYMENT OF EXPENSES AND CHARGES. Each of the Obligors
         shall be obligated, jointly and severally, to pay to the Trustee all
         out-of-pocket expenses (including court costs and reasonable attorneys'
         fees and expenses) of, or incident to, the enforcement of any of the
         provisions of this Agreement and all other charges due against the
         Collateral, including, without limitation, taxes, assessments, security
         interests, Liens or encumbrances upon the Collateral and any expenses,
         including transfer or other taxes, arising in connection with any sale,
         transfer or other disposition of Collateral.

         5.2 OTHER ENFORCEMENT RIGHTS.

         The Trustee may proceed to protect and enforce this Agreement by suit
or suits or proceedings in equity, at law or in bankruptcy, and whether for the
specific performance of any covenant or agreement in this Agreement contained or
in execution or aid of any power in this Agreement granted, or for foreclosure
under this Agreement, or for the appointment of a receiver or receivers for the
Collateral or any part thereof, for the recovery of judgment for the obligations
secured by this Agreement or for the enforcement of any other proper, legal or
equitable remedy available under applicable law.

         5.3 POWER OF ATTORNEY.

         Each Obligor hereby makes, constitutes and appoints the Trustee the
true and lawful agent and attorney in fact of such Obligor with full power of
substitution:

                  (a) if an Event of Default shall exist, to receive, open and
         dispose of all mail addressed to such Obligor and remove therefrom any
         notes, checks, drafts, money orders or other instruments included in
         the Collateral, with full power to endorse the name of such Obligor
         upon any such checks, drafts, money orders, or other instruments
         relating to the Collateral and to effect the deposit and collection
         thereof, and the further right and power to endorse the name of such
         Obligor on any other document relating to the Collateral;

                  (b) if an Event of Default exists, to sign the name of such
         Obligor to drafts against its debtors, to notices to such debtors, to
         assignments and notices of assignments, financing statements,
         continuation statements or other public records or notices and all
         other instruments and documents; and

                  (c) to do any and all things necessary to take action in the
         name and on behalf of such Obligor to carry out the provisions of this
         Agreement.

Each of the Obligors agrees, in the absence of willful wrongdoing or gross
negligence, that neither the Trustee nor any of its agents, designees or
attorneys-in-fact will be liable for any acts of commission or omission, or for
any error of judgment or mistake of fact or law with respect to the exercise of
the power of attorney granted under this Section . The power of attorney

   27
                                                         5. DEFAULTS -- REMEDIES

granted under this Section is coupled with an interest and shall be irrevocable
so long as any Secured Obligation remains outstanding.

         5.4 EFFECT OF SALE, ETC.

                  (a) TITLE. Any sale or sales pursuant to the provisions of
         this Agreement, whether under any right or power granted hereby or
         pursuant to any legal proceedings, shall operate to divest each of the
         Obligors of all of any such Obligor's right, title, interest, claim and
         demand whatsoever, either at law or in equity, of, in and to the
         Collateral, or any part thereof, so sold, and any Property so sold
         shall be free and clear of any and all rights of redemption by, through
         or under such Obligor. At any such sale any holder of Secured
         Obligations may, to the extent permitted by applicable law, bid for and
         purchase the Property sold and may make payment therefor as set forth
         in Section , and any such Person so purchasing any such Property, upon
         compliance with the terms of sale, may hold, retain and dispose of such
         Property without further accountability.

                  (b) APPLICATION OF PROCEEDS. The receipt by the Trustee, or by
         any Person authorized under any judicial proceedings to make any such
         sale, of the proceeds of any such sale shall be a sufficient discharge
         to any purchaser of the Collateral, or of any part thereof, sold as
         aforesaid; and no such purchaser shall be bound to see to the
         application of such proceeds, or be bound to inquire as to the
         authorization, necessity or propriety of any such sale. In the event
         that, at any such sale, any holder of Secured Obligations is the
         successful purchaser, it shall be entitled, for the purpose of making
         settlement or payment, to use and apply such Collateral to its Secured
         Obligations by crediting thereon the amount apportionable and
         applicable thereto out of the net proceeds of such sale.

         5.5 DELAY OR OMISSION; NO WAIVER.

         No course of dealing on the part of the Trustee or any holder of
Secured Obligations nor any delay or failure on the part of the Trustee or such
holder to exercise any right shall impair such right or operate as a waiver of
such right or otherwise prejudice the Trustee's or such holder's rights, powers
and remedies. No waiver by the Trustee or any holder of Secured Obligations of
any Default or Event of Default, whether such waiver be full or partial, shall
extend to or be taken to affect any subsequent Default or Event of Default, or
to impair the rights resulting therefrom except as may be otherwise expressly
provided in this Agreement. Every right and remedy given by this Agreement, by
any other Lending Document or by law to the Trustee or any holder of Secured
Obligations may be exercised from time to time as often as may be deemed
expedient by such Person.

         5.6 RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee shall have instituted any proceeding to enforce any
right or remedy under this Agreement or under any other Lending Document and
such proceeding shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Trustee, the Obligors and the Beneficiaries shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions under this Agreement and under the other Lending
Documents, and thereafter

all rights and remedies of the Trustee and such Beneficiaries shall continue as
though no such proceeding had been instituted.

         5.7 APPLICATION OF PROCEEDS.

         The proceeds of any exercise of rights with respect to the Collateral,
or any part thereof, and the proceeds and the avails of any remedy under this
Agreement shall be paid to the Trustee and applied by the Trustee in accordance
with the provisions of the Trust Indenture. If there is a deficiency, each of
the Obligors shall, subject always to the other provisions of this Agreement,
remain liable therefor and shall forthwith pay the amount of any such deficiency
to the Trustee.

         5.8 CUMULATIVE REMEDIES.

         No remedy under this Agreement or under any other Lending Document is
intended to be exclusive of any other remedy, but each and every remedy shall be
cumulative and in addition to any and every other remedy given under this
Agreement or under any other Lending Document or otherwise existing; nor shall
the giving, taking or enforcement of any other or additional security,
collateral or guaranty for the payment or performance of the Secured Obligations
operate to prejudice, waive or affect the security of this Agreement or any
rights, powers or remedies under this Agreement, nor shall the Trustee or the
holder of any Secured Obligation be required to look first to, enforce or
exhaust any such other or additional security, collateral or guaranties.

         5.9 WAIVERS BY THE OBLIGORS.

                  (a) Each of the Obligors hereby waives notice of acceptance of
         this Agreement. Each of the Obligors further waives presentment and
         demand for payment of any of the Secured Obligations, protest and
         notice of dishonor or default with respect to any of the Secured
         Obligations, and all other notices to which such Obligor might
         otherwise be entitled.

                  (b) Each of the Obligors (to the extent that it may lawfully
         do so) covenants that it shall not at any time insist upon or plead, or
         in any manner claim or take the benefit or advance of, any stay (except
         in connection with a pending appeal), valuation, appraisal, redemption
         or extension law now or at any time hereafter in force that, but for
         this waiver, might be applicable to any sale made under any judgment,
         order or decree based on this Agreement or any other Lending Document;
         and each of the Obligors (to the extent that it may lawfully do so)
         hereby expressly waives and relinquishes all benefit and advance of any
         and all such laws and hereby covenants that it will not hinder, delay
         or impede the execution of any power in this Agreement or therein
         granted and delegated to the Trustee, but that it will suffer and
         permit the execution of every such power as though no such law or laws
         had been made or enacted.

         5.10 CONSENT.

         Each of the Obligors hereby consents that from time to time (before or
after the occurrence or existence of any Event of Default, with or without
notice to or assent from such Obligor)

                  (a) any Collateral or other security at any time held by or
         available to the Trustee or any holder of Secured Obligations for any
