                      FIRST AMENDMENT TO GUARANTY AGREEMENT

     THIS FIRST AMENDMENT TO GUARANTY AGREEMENT (this "Amendment") is made as of
the 28th day of February, 2002, by and among BELDEN COMMUNICATIONS COMPANY and
BELDEN WIRE & CABLE COMPANY, (the "Guarantors") subsidiaries of Belden Inc., a
Delaware corporation (the "Borrower") and WACHOVIA BANK, N.A., as Administrative
Agent (the "Agent").

                                R E C I T A L S:
                                ----------------

     The Guarantors have entered into a certain Guaranty Agreement dated as of
June 21, 2001 (the "Guaranty Agreement"). Capitalized terms used in this
Amendment which are not otherwise defined in this Amendment shall have the
respective meanings assigned to them in the Guaranty Agreement.

     The Guarantors have requested the Agent to amend the Guaranty Agreement as
more fully set forth herein. The Agent and the Guarantors desire to amend the
Guaranty Agreement upon the terms and conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the Recitals and the mutual promises
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Guarantors and the Agent,
intending to be legally bound hereby, agree as follows:

     SECTION 1. Recitals. The Recitals are incorporated herein by reference and
shall be deemed to be a part of this Amendment.

     SECTION 2. Amendments. The Guaranty Agreement is hereby amended by amending
and restating Section 4 in its entirety to read as follows:

          SECTION 4. The Guaranty. Each Guarantor hereby unconditionally
     guarantees, jointly and severally, the full and punctual payment when due
     (whether at stated maturity, upon acceleration or otherwise) of the
     principal of and interest on each Loan made pursuant to the Credit
     Agreement, all obligations of the Borrower pursuant to Hedging Agreements
     between the Borrower and any Lender, all indemnity obligations of the
     Borrower, and all other amounts payable by the Borrower under the Credit
     Agreement and the other Loan Documents (all of the foregoing, including
     without limitation, interest accruing or that would have accrued thereon
     after the filing of a petition in bankruptcy or other insolvency
     proceeding, being referred to collectively as the "Guaranteed
     Obligations"). Upon failure by the Borrower to pay punctually any such
     amount, each Guarantor agrees that it shall forthwith on demand pay the
     amount not so paid at the place and in the manner specified in the Credit
     Agreement, each Note,

                                       1

     or the relevant Loan Documents, as the case may be. Each Guarantor
     acknowledges and agrees that this is a guarantee of payment when due, and
     not of collection, and that this Guaranty may be enforced up to the full
     amount of the Guaranteed Obligations without proceeding against the
     Borrower, any security for the Guaranteed Obligations, or against any other
     party that may have liability on all or any portion of the Guaranteed
     Obligations.

     SECTION 3. Conditions to Effectiveness. The effectiveness of this Amendment
is subject to the following conditions, unless the Agent waives such conditions:

          (a)  receipt by the Agent from each of the parties hereto of a duly
     executed counterpart of this Amendment signed by such party;

          (b)  the fact that the representations and warranties of each of the
     Guarantors contained in Section 5 of this Amendment shall be true on and as
     of the date hereof.

     SECTION 4. No Other Amendment. Except for the amendment set forth above,
the text of the Guaranty Agreement shall remain unchanged and in full force and
effect. This Amendment is not intended to effect, nor shall it be construed as,
a novation. The Guaranty Agreement and this Amendment shall be construed
together as a single agreement. Nothing herein contained shall waive, annul,
vary or affect any provision, condition, covenant or agreement contained in the
Guaranty Agreement, except as herein amended, nor affect nor impair any rights,
powers or remedies under the Guaranty Agreement as hereby amended. The Agent
hereby reserves all of its rights and remedies against all parties who may be or
may hereafter become secondarily liable for the repayment of the Guaranteed
Obligations. Each of the Guarantors promises and agrees to perform all of the
requirements, conditions, agreements and obligations under the terms of the
Guaranty Agreement, as heretofore and hereby amended, the Guaranty Agreement, as
amended, being hereby ratified and affirmed. Each of the Guarantors hereby
expressly agree that the Guaranty Agreement, as amended, is in full force and
effect.

     SECTION 5. Representations and Warranties. Each Guarantor hereby represents
and warrants to the Agent as follows:

          (a)  No Default or Event of Default, nor any act, event, condition or
     circumstance which with the passage of time or the giving of notice, or
     both, would constitute an Event of Default, under the Guaranty Agreement or
     any other Loan Document has occurred and is continuing unwaived by the
     Lenders on the date hereof.

          (b)  Each Guarantor has the power and authority to enter into this
     Amendment and to do all acts and things as are required or contemplated
     hereunder, or thereunder, to be done, observed and performed by it.

                                       2

          (c)  This Amendment has been duly authorized, validly executed and
     delivered by one or more authorized officers of each Guarantor and
     constitutes legal, valid and binding obligations of each of the Guarantors
     enforceable against each of them in accordance with their terms, provided
     that such enforceability is subject to general principles of equity.

          (d)  The execution and delivery of this Amendment and each of the
     Guarantor's performance hereunder do not and will not require the consent
     or approval of any regulatory authority or governmental authority or agency
     having jurisdiction over either Guarantor, nor be in contravention of or in
     conflict with the articles of incorporation or bylaws of either of the
     Guarantors, or the provision of any statute, or any judgment, order or
     indenture, instrument, agreement or undertaking, to which either of the
     Guarantors is party or by which either of the Guarantors' assets or
     properties are or may become bound.

     SECTION 6. Counterparts. This Amendment may be executed in multiple
counterparts, each of which shall be deemed to be an original and all of which,
taken together, shall constitute one and the same agreement.

     SECTION 7. Governing Law. This Amendment shall be construed in accordance
with and governed by the laws of the State of Georgia.

                             AMENDMENT NO. 1 TO THE
                           NOBLE DRILLING CORPORATION
                         401(k) SAVINGS RESTORATION PLAN

         Pursuant to the provisions of Section 4.1 thereof, the Noble Drilling
Corporation 401(k) Savings Restoration Plan (the "Plan") is hereby amended in
the following respects only:

         FIRST: Section 1.1(o) of the Plan is hereby amended by restatement in
its entirety to read as follows:

                  (o) "Unit Value" means an amount equal to (i) if the ordinary
         shares of Noble Corporation, a Cayman Islands exempted company limited
         by shares and the ultimate parent corporation of the Employers, are
         listed or admitted to trading on a securities exchange registered under
         the Securities Exchange Act of 1934, the average of the closing sale
         prices per share of such shares as reported on the principal such
         exchange for the immediately preceding five days on which a sale of
         such shares was reported on such exchange, (ii) if the ordinary shares
         of Noble Corporation are not listed or admitted to trading on any such
         exchange, but are listed as a national market security by the National
         Association of Securities Dealers, Inc. Automated Quotations System
         ("NASDA") or any similar system then in use, the average of the closing
         sale prices per share of such shares as reported on NASDAQ or such
         system for the immediately preceding five days on which a sale of such
         shares was reported on NASDAQ or such system, and (iii) if the ordinary
         shares of Noble Corporation are not listed or admitted to trading on
         any such exchange and are not listed as a national market security on
         NASDAQ or any similar system then in use, but are quoted on NASDAQ or
         any similar system then in use, the average of the mean between the
         closing high bid and low asked quotations per share for such shares as
         reported on NASDAQ or such system for the immediately preceding five
         days on which bid and asked quotations for such shares were reported on
         NASDAQ or such system.

         SECOND: Section 3.2(b) of the Plan is hereby amended by restatement in
its entirety to read as follows:

                  (b) The number of Units equal to the number of the ordinary
         shares of Noble Corporation that would have been contributed to the
         401(k) Plan as an Employer Matching Contribution for such Participant
         for each month during a Plan Year if the compensation such Participant
         elected to defer for such month pursuant to Plan Section 3.1(i) had
         been contributed to the 401(k) Plan as a pre-tax contribution for such
         Participant for such month shall be credited to such Participant's
         Matching Account for that year no later than 15 business days after the
         end of such month.

                                       1

<PAGE>

         THIRD: Section 3.4 of the Plan is hereby amended by restatement in its
entirety to read as follows:

                  Section 3.4 Unit Adjustments. If a cash dividend is paid on
         the ordinary shares of Noble Corporation, each Account then credited
         with a Unit shall be credited on the date said dividend is paid with
         the number of Units equal to the amount of said dividend per share
         multiplied by the number of Units then credited to such Account, with
         the product thereof divided by the Unit Value on the date such dividend
         is paid. If Noble Corporation effects a split of its ordinary shares or
         pays a dividend in the form of its ordinary shares, or if the
         outstanding ordinary shares of Noble Corporation are combined into a
         smaller number of shares, the Units then credited to an Account shall
         be increased or decreased to reflect proportionately the increase or
         decrease in the number of outstanding ordinary shares of Noble
         Corporation resulting from such split, dividend or combination. In the
         event of a reclassification of the ordinary shares of Noble Corporation
         not covered by the foregoing, or in the event of a liquidation,
         separation or reorganization (including, without limitation, a merger,
         amalgamation, consolidation or sale of assets) involving Noble
         Corporation, the Board of Directors of the Company shall make such
         adjustments, if any, to an Account as such Board may deem appropriate.

         FOURTH: The last paragraph of Section 3.5 of the Plan is hereby amended
by restatement in its entirety to read as follows:

                  When Units credited to an Account maintained by an Employer
         for a Participant become distributable, such Units shall be canceled
         and the Employer maintaining such Account shall deliver or cause to be
         delivered to the distributee a certificate evidencing the ownership of
         one ordinary share of Noble Corporation for each Unit so canceled;
         provided, however, that if the rules of any stock exchange or stock
         market on which the ordinary shares of Noble Corporation are listed
         require member approval of the Plan as a prerequisite for listing on
         such stock exchange or stock market the ordinary shares of Noble
         Corporation deliverable under the Plan, then, unless and until such
         member approval is obtained, all ordinary shares of Noble Corporation
         delivered pursuant to the Plan shall be shares acquired by such
         Employer (or a trustee acting on behalf of such Employer) either in the
         open market or from Noble Corporation or one of its affiliates. When an
         amount credited as a dollar amount to an Account maintained by an
         Employer for a Participant becomes distributable, such amount shall be
         paid by such Employer to the distributee in cash and charged against
         such Account. If the amount credited to an Account is paid in
         installments over a period of years, the provisions of Plan Sections
         3.3 and 3.4 shall continue to apply to the amount credited to such
         Account from time to time. An Employer making a payment or causing
         ordinary shares of Noble Corporation to be delivered to or with respect
         to a Participant pursuant to this Plan shall withhold from any such
         payment or delivery and shall remit to the appropriate governmental
         authority, any income, employment or other tax such Employer is
         required by applicable law to so withhold from and remit on behalf of
         the payee.

                                       2

         FIFTH: Section 5.1 of the Plan is hereby amended by restatement in its
entirety to read as follows:

                  Section 5.1 Nature of Plan and Rights. This Plan is unfunded
         and maintained by the Employers primarily for the purpose of providing
         deferred compensation for a select group of management or highly
         compensated employees of the Employers. The Units credited and Accounts
         maintained under this Plan are fictional devices used solely for the
         accounting purposes of this Plan to determine an amount of money to be
         paid and a number of ordinary shares of Noble Corporation to be
         delivered by an Employer to a Participant pursuant to this Plan, and
         shall not be deemed or construed to create a trust fund or security
         interest of any kind for or to grant a property interest of any kind to
         any Participant, designated beneficiary or estate. The amounts credited
         by an Employer to Accounts maintained under this Plan are and for all
         purposes shall continue to be a part of the general liabilities of such
         Employer, and to the extent that a Participant, designated beneficiary
         or estate acquires a right to receive a payment from such Employer
         pursuant to this Plan, such right shall be no greater than the right of
         any unsecured general creditor of such Employer.

         IN WITNESS WHEREOF, this Amendment has been executed by Noble Drilling
Corporation on behalf of all Employers to be effective as of May 1, 2002.
