(the "Documentation Agent").

                                    RECITALS

         A.       The Borrowers, the Agents and certain Lenders (the "Existing
Lenders") are party to that certain 364-Day Credit Agreement dated as of October
20, 1999 (the "Credit Agreement"). Unless otherwise specified herein,
capitalized terms used in this Amendment shall have the meanings ascribed to
them by the Credit Agreement.

         B.       The Borrowers, the Agents and the Existing Lenders wish to
amend the Credit Agreement on the terms and conditions set forth below.

         C.       The Lenders which are not Existing Lenders wish to become
parties to the Credit Agreement.

         Now, therefore, in consideration of the mutual execution hereof and
other good and valuable consideration, the parties hereto agree as follows:

         1.       Amendment to Credit Agreement. Upon the "Effective Date" (as
defined below), the Credit Agreement shall be amended as follows:

                  (a)      Section 1.1 of the Credit Agreement is amended by
deleting the definitions of "Dividend", "Lenders" and "Required Lenders" and
replacing them with the following definitions:

         "'DIVIDEND' means the cash distribution of approximately $568,000,000
         (which amount gives effect to a positive cash adjustment of
         approximately $23,000,000 in favor of the Company pursuant to the
         Spin-Off Materials) to be paid by the Company to Harris in connection
         with the Spin-Off. Notwithstanding anything in this Agreement to the
         contrary, (i) such distribution may take the form of a redemption by
         the Company of shares in the Company held by Harris in exchange for
         cash or promissory notes in the approximate amount of $568,000,000
         followed by the repayment or redemption of such notes in full for cash
         on the Closing Date and (ii) such transactions shall not be deemed to
         give rise to a Default or Unmatured Default or to result in any
         representation or warranty of the Borrowers in any Loan Document being
         untrue or incorrect."

         "'LENDERS' means the lending institutions listed on the signature pages
         of Amendment No. 1 to this Agreement, dated as of November 4, 1999, and
         their successors and assigns."

         "'REQUIRED LENDERS' means Lenders hereunder whose Pro Rata Shares, in
         the aggregate, are at least fifty-one percent (51%); provided,
         however, that solely with respect to any waiver or amendment of the

         Revolving Loan Commitments hereunder and "Commitments" under the 5-Year
         Credit Agreement of the Agents (in their individual capacities) and
         their Affiliates are $330,000,000 or less, "Required Lenders" shall
         mean Lenders hereunder whose Pro Rata Shares, in the aggregate, are at

         by the appropriate governmental officer in its jurisdiction of
         incorporation (or, in the case of Lanier Europe AG, as may otherwise be
         satisfactory to the Administrative Agent)."

                  (e)      Section 5.1(O) of the Credit Agreement is deleted in
its entirety and replaced with the following:

         required to be paid on or before the Closing Date (including, without
         limitation, the commitment fees provided for in Section 2.15(C) of this
         Agreement, which fees, with respect to the period prior to the
         effectiveness of Amendment No. 1 to this Agreement, shall be solely for
         the account of the Lenders signatory to the Agreement as of October 20,
         1999)."

         transaction which is otherwise permitted by the Credit Agreement."

         2.       Representations and Warranties of the Borrowers. Each Borrower

are hereby ratified and confirmed.

                  (b)      The execution, delivery and effectiveness of this
Amendment shall not operate as a waiver of any right, power or remedy of any
Agent or Lender under the Credit Agreement or any other Loan Document, or
constitute a waiver of any provision of the Credit Agreement or any Loan
Document, except as specifically set forth herein. Upon the effectiveness of
this Amendment, each reference in the Credit Agreement to "this Agreement",
"hereunder", "hereof", "herein" or words of similar import shall mean and be a
reference to the Credit Agreement as amended hereby, and each reference in the
other Loan Documents to the Credit Agreement shall mean and be a reference to
the Credit Agreement as amended hereby.

                  5.       Costs and Expenses. Each Borrower hereby affirms its
