                           (iv)     The Borrower and its Subsidiaries shall,
         together with the Administrative Agent and its advisors, engage in
         extensive business and legal due diligence (including, without
         limitation, an assessment of the claims and priority of local lines of
         credit) with respect to the Foreign Subsidiaries to assess and explore
         opportunities for such Foreign Subsidiaries to grant security
         interests in their assets in favor of the Administrative Agent for the
         benefit of the Lenders. Upon consideration of the foregoing, by
         January 15, 2002, the Administrative Agent shall deliver to the
         Borrower a schedule of security agreements, mortgages and guarantees,
         among other things, required to be executed by Foreign Subsidiaries
         (the "Foreign Collateral Schedule"). The Borrower shall, on or before
         February 15, 2002, deliver to the Administrative Agent and the Lenders
         the security agreements, mortgages and guarantees listed on the
         Foreign Collateral Schedule, together with all documents and
         instruments necessary to perfect the security interests granted in
         such


                                      11

         security agreements and such legal opinions as the Administrative
         Agent may request, in each case, in form and substance satisfactory to
         the Administrative Agent and the Required Lenders.

                           (v)      In the event that the Administrative Agent
         determines to undertake an independent valuation of the consolidated
         enterprise value of the Borrower and its Subsidiaries, which
         undertaking may be done or updated from time to time, the Borrower and
         its Subsidiaries shall cooperate in all respects with any such
         valuation advisor selected by the Administrative Agent. Moreover, the
         Borrower and its Subsidiaries shall furnish the Agent with any written
         appraisal or valuation report received by them with respect to the
         consolidated enterprise value of the Borrower and its Subsidiaries, as
         soon as available and in any event within five business days of
         receipt.

                           (vi)     The Borrower and its Subsidiaries shall
         permit the Administrative Agent, the Lenders and their advisors to
         visit and inspect their properties (including their books and records,
         accounts receivable and inventory, facilities and other business
         assets) as often as requested. The Borrower and its Subsidiaries shall
         authorize and direct all their accountants and auditors to deliver
         copies of any of the financial statements, trial balances or other
         accounting records of any sort and to disclose to the Administrative
         Agent, the Lenders and their advisors any information they may have
         concerning the financial status and business operation of the Borrower
         and its Subsidiaries.

                           (vii)    The Borrower, its Subsidiaries and their
         advisors shall fully cooperate with the Administrative Agent and its
         advisors with respect to the analysis of domestic and foreign
         collateral matters, including in connection with the valuation of the
         consolidated enterprise value. The Borrower shall reimburse the
         Administrative Agent for all costs and out-of-pocket expenses incurred
         in connection therewith.

                  (h)      Dissolution of Certain Subsidiaries. The Borrower
hereby represents and warrants that none of Electro Fiberoptics Corp., CML
Fiberoptics, Inc., McLight Distribution, or VCH Incorporated own, directly or
indirectly, any assets or other property or conduct any business, and shall not
after the Effective Date own, directly or indirectly, any assets or other
property or conduct any business. The Borrower shall dissolve and wind up each
of Electro Fiberoptics Corp., CML Fiberoptics, Inc., McLight Distribution, and
VCH Incorporated, within 90 days of the Effective Date and shall provide the
Lenders with reasonable documentation of such dissolution within such time
period.

                  Section 3.2.      Agreements Deemed Agreements under the
Credit Agreement. For purposes of the Credit Agreement, the agreements of the
Borrower contained in this Article III shall be deemed to be, and shall be,
agreements under the Credit Agreement. Any breach on the part of the Borrower
in respect of any agreement contained herein shall constitute an Event of
Default.

required by the Administrative Agent), documents, and instruments as are
customary for transactions of this type or as the Administrative Agent or any
Lender may reasonably request;

                  (d)      payment in full in cash of its invoiced and unpaid
fees and out-of-pocket expenses incurred in connection with the Credit
Agreement, including, without limitation, the reasonable fees and disbursements
of counsel to the Administrative Agent and any financial advisor retained by
counsel to the Administrative Agent.

The Borrower, the Administrative Agent and each Lender hereby acknowledges and
agrees that the Credit Agreement shall continue to be and shall remain
unchanged and in full force and effect in accordance with its terms, except as

shall control over any inconsistent terms or conditions in the Credit Agreement
or the other Loan Documents.

                  Section 5.2.      No Waiver. Nothing contained in this

Default or Event of Default.

                                  ARTICLE VI
                                 MISCELLANEOUS

(the "First Installment"), (ii) $950,000 in cash on January 31, 2002 and (iii)
$950,000 in cash on April 1, 2002 (the "Third Installment"); provided, that the

                  (c)      The Borrower shall, on the first Business Day of
each fiscal quarter, pay to the Administrative Agent, for the account of each
Lender on a pro rata basis, a fee (the "Overage Fee") in an amount equal to (i)
0.50% multiplied by (ii) the amount by which (A) the Total Exposure as of such

such day) exceeds (B) the Target Exposure as of such day.

                  Section 6.3.      Confirmation of Indebtedness. The Borrower
and the Guarantors hereby confirm and acknowledge that, as of the Effective
Date, (i) the Borrower is truly and justly indebted to the Lenders, without

Letters of Credit) and (iii) each Guarantor is contingently liable to the
Lenders in respect of such amount.

                  Section 6.4.      Counterparts. This Amendment may be
executed by the parties hereto in any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument.

                  Section 6.5.      GOVERNING LAW. THIS AMENDMENT AND THE
RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AMENDMENT SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE

PRINCIPLES).

                  Section 6.6.      Reservation of Rights. Notwithstanding
anything contained in this Amendment, the Borrower acknowledges that the
Administrative Agent and the Lenders do not waive, and expressly reserve, the
right to exercise, at any time, any and all of their rights and remedies under

                  Section 6.7.      Waiver. The Borrower and each of the
Guarantors hereby releases, waives, and forever relinquishs all claims,
demands, obligations, liabilities and causes of action of whatever kind or

assert at the time of execution of this Amendment or in the future against the
Administrative Agent, the Lenders and/or their respective parents, affiliates,
participants, officers, directors, employees, agents, attorneys, accountants,
consultants, successors and assigns (collectively, the "Lender Group"),
directly or indirectly, which occurred, existed, was taken, permitted or begun
prior to the execution of this Amendment, arising out of, based upon, or in any
manner connected with (i) any transaction, event, circumstance, action, failure
to act or occurrence of any sort or type, whether known or unknown, with
respect to the Credit Agreement, any other Loan Document and/or the
administration thereof or the obligations created thereby, (ii) any
discussions, commitments, negotiations, conversations or communications with
respect to the refinancing, restructuring or collection of any obligations

                  Section 6.8.      Joinder. To induce the Lenders to continue
to make Loans available from time to time to the Borrower, each Subsidiary
listed on the signature pages hereto hereby affirms its status as a "Guarantor"
under the Credit Agreement or, to the extent applicable, agrees to become a
"Guarantor" under the Credit Agreement with the same force and effect as if
such Subsidiary was a signatory thereto. Each such Subsidiary shall be jointly
and severally liable to each Lender, any Issuing Lender and the Administrative
Agent and their respective successors and assigns the prompt payment in full
when due (whether at stated


                                      14
<PAGE>


maturity, by acceleration or otherwise) of the Guarantied Obligations and each
such Subsidiary agrees that if the Guarantied Obligations are not paid in full
when due (whether at stated maturity, by acceleration or otherwise) such
Subsidiary shall promptly pay the same, without any demand or notice whatsoever
and in the case of any extension of time for payment or renewal of any of the
Guaranteed Obligations, the same will be promptly paid in full when due
(whether at stated maturity, by acceleration or otherwise) in accordance with
the terms of such extension of time for payment or renewal. Moreover, to induce
the Lenders to continue to make Loans available from time to time to the
Borrower, each Subsidiary listed on the signature pages hereto hereby affirms
its status as a "Debtor" under the Amended and Restated Security Agreement,
dated as of October 29, 1999 by and among the Borrower, certain of its
Subsidiaries parties thereto and the Administrative Agent (the "Security
Agreement") or, to the extent applicable, agrees to become a "Debtor" under the
Security Agreement with the same force and effect as if such Subsidiary was a
signatory to such agreement and was expressly named as a "Debtor" therein and
each Subsidiary hereby grants to the Administrative Agent, for itself and for
the benefit of the other Lenders a security interest in all of its Collateral
(as defined in the Security Agreement).
