      This RESTRUCTURING AGREEMENT dated as of April 30, 2002 (this
"AGREEMENT") is made and entered into by and among HY I INVESTMENTS, L.L.C.,
THOSE INVESTMENT FUNDS MANAGED BY BENNETT MANAGEMENT CORPORATION AND ITS
AFFILIATED ENTITIES AND THAT HOLD OLD NOTES (as defined below) (together, the
"HOLDERS") and PENTACON, INC., a Delaware corporation (the "COMPANY").

      WHEREAS, the Holders and the Company have each determined that it is
advisable and in their respective best interests to consummate the transaction
provided for herein in which the Company would make an offer to acquire all of
the issued and outstanding 12.25% Senior Subordinated Notes due 2009 of the
Company ("OLD NOTES") in exchange for new notes and preferred stock upon the
terms and subject to the conditions of this Agreement; and

      WHEREAS, the Holders and the Company desire to make certain
representations, warranties and agreements in connection with the transactions
contemplated by this Agreement and also to prescribe various conditions to the
consummation of such transactions;

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                                 ARTICLE I

                                 THE OFFER

      1.01 THE OFFER. (a) Subject to the other terms hereof and provided that
this Agreement shall not have been terminated in accordance with SECTION 6.01,
the Company, as promptly as is practicable after the date hereof but in any
event not later than 30 days after the date hereof, shall commence (within the
meaning of applicable rules under the Securities Exchange Act of 1934, as
amended (such Act and the rules and regulations promulgated thereunder being
referred to herein as the "EXCHANGE ACT")) and will pursue an exchange offer
(the "OFFER") to acquire all of the issued and outstanding Old Notes on the
basis that the exchanging holders of Old Notes shall share ratably, according
to the principal amount of Old Notes exchanged by each such holder in relation
to the aggregate principal amount of Old Notes exchanged by all holders of Old
Notes tendering their Old Notes pursuant to the Offer, of (i) $35,000,000
principal amount of the Company's Senior Subordinated PIK Notes due 2007 (the
"NEW NOTES") to be issued under an indenture to be in form and substance
satisfactory to the Company and the Holders, and (ii) shares of the Company's
capital stock (either common or convertible preferred stock having the
designations and preferences agreed to among the Company and the Holders) (the
"NEW STOCK")), in either case, entitling the noteholders participating in the
Offer to 90% of the voting control and rights to distributions in respect of
the Company. In connection with the Offer, the Company agrees to solicit
consents (the "CONSENT SOLICITATION") to an amendment of the Indenture dated as
of March 30, 1999 (the "OLD INDENTURE") by and among the Company, the
guarantors named therein and State Street Bank and Trust Company, as trustee,
to be in form and substance satisfactory to the Company and the Holders,
waiving current defaults under, and substantially modifying the covenants and

<Page>


restrictions under, the Old Indenture (such amendment being the "INDENTURE
AMENDMENT"). The Company shall not waive any condition to, or make any changes
in the terms and conditions of, the Offer or the Plan (as defined below)
without the unanimous consent of the Holders; PROVIDED, HOWEVER, the Offer may
be extended by the Company to any date on or before June 30, 2002 (the "FINAL
EXPIRATION DATE") if (x) immediately prior to the expiration of the Offer any
condition to the Offer shall not be satisfied and (y) the Board of Directors of
the Company (the "BOARD OF DIRECTORS") determines there is a reasonable basis
to believe that such condition could be satisfied within such period; PROVIDED
FURTHER that the Company shall extend the Offer at the request of the Holders
from time to time to a date not later than the Final Expiration Date. Assuming
the prior satisfaction or waiver of the conditions of the Offer and subject to
the foregoing right to extend the Offer, the Company shall issue the New Notes
and the New Stock in exchange for Old Notes tendered pursuant to the Offer as
soon as practicable after the Company accepts Old Notes for exchange under the
Offer (the "CONSUMMATION DATE"). The Offer shall be conducted in such a manner
that the issuance of the New Notes and New Stock shall be exempt from
registration under Section 4(2) of the Securities Act of 1933, as amended (the
"SECURITIES ACT").

      (b) As soon as practicable on the date of commencement of the Offer, the
Company shall take such steps as are reasonably necessary to cause a
Confidential Offering Memorandum and Consent Solicitation and a related Letter
of Transmittal, each in a form customary for a transaction of the type
contemplated hereunder, to be disseminated to the holders of Old Notes as and
to the extent required by applicable federal securities laws (the Confidential
Offering Memorandum and Consent Solicitation, Letter of Transmittal and any
related summary advertisement, together with all amendments and supplements
thereto, the "OFFER DOCUMENTS"), which Offer Documents shall incorporate the
material terms of this Agreement and other customary terms. The Holders and the
Company shall correct promptly any information provided by any of them for use
in the Offer Documents which shall have become false or misleading, and the
Company shall take all steps necessary to cause the Offer Documents as so
corrected to be disseminated to holders of Old Notes, in each case as and to
the extent required by applicable federal securities laws. The Holders and
their counsel shall be given an opportunity to review and comment on the Offer
Documents prior to the dissemination of such Offer Documents. The Company and
the Holders shall cooperate with each other in the preparation of the Offer
Documents.

      (c) Subject to the terms hereof, the Company shall use commercially
reasonable efforts to complete the Offer and the Consent Solicitation in
accordance with the terms hereof. Upon satisfaction of all conditions to the
Offer, the Company shall complete the Offer and accept the Old Notes for
exchange of New Notes and New Stock in accordance with the terms of the Offer
and shall execute the Indenture Amendment, in each case as soon as reasonably
practicable following the expiration of the Offer.

      (d) Notwithstanding the foregoing, at any time prior to the Consummation
Date (including after commencement of the Offer), the Company may elect to
implement the Offer by means of a pre-negotiated Chapter 11 plan of
reorganization filed under 11 U.S.C. Sections 101 et. seq. (the "BANKRUPTCY
CODE") on terms materially identical to the Offer or as otherwise agreed to by
the Holders and the Company (the "PLAN"). The Company and the Holders shall
cooperate with


                                       2
<Page>


each other in the preparation of any such Plan and the Holders and their
counsel shall have the opportunity to review and comment on the Plan prior to
its filing. The Holders shall approve such Plan prior to its filing by the
Company. Without limiting the foregoing, the Plan will not be deemed to have
terms materially identical to the Offer unless:

            (i) indebtedness owed to the Company's senior bank lenders will
      either be (x) repaid in full in cash on the effective date of the Plan
      (the "EFFECTIVE DATE") or on such other terms as are acceptable to the
      senior bank lenders or (y) restructured on terms acceptable to the senior
      bank lenders, the Company and the Holders;

            (ii) accounts payable which are due and owing to the trade creditors
      of the Company will be either (x) paid in full on the Effective Date or
      (y) restructured or compromised on terms acceptable to such creditors, the
      Company and the Holders;

            (iii) the holders of Old Notes will receive their pro rata
      proportion of (x) New Stock of the Company, which stock shall be the only
      class of stock outstanding and shall entitle the holders to 90% of the
      voting rights and rights to distributions and (y) $35,000,000 original
      principal amount of New Notes to fully discharge the claims represented by
      the Old Notes (such New Stock and New Notes to contain such terms and
      entitlements as are acceptable to the Holders);

            (iv) the amount of New Stock distributed to holders of common stock
      on the date of the confirmation of the Plan (the "CONFIRMATION DATE")
      represents 10% of the sum of the New Stock to be issued to the holders of
      Old Notes and such shareholders on the Effective Date;

            (v) the management incentives are issued and reserved as
      contemplated by Section 5.02 hereof.

            1.02 HOLDER ACTIONS. (a) Subject to the terms and conditions of this
Agreement, each Holder hereby severally approves and consents to the Offer or,
conversely, such Plan, and severally agrees to tender or cause to be tendered
all Old Notes beneficially owned by it pursuant to the Offer and to vote or
cause to be voted all such Old Notes in favor of the Indenture Amendment;
PROVIDED, that if at any time the Company receives a bona fide offer for the
purchase of the stock and/or Old Notes or all or substantially all of the assets
of the Company or for the merger or consolidation of the Company with or into
any other company (collectively, an "ALTERNATIVE OFFER"), which the Board of
Directors and the Holders, in good faith after consultation with each other,
determine to be superior to the Offer or Plan (a "SUPERIOR OFFER"), then the
Holders shall have the right, prior to the Consummation Date of the Offer or the
Effective Date of any such Plan, to rescind their approval and consent to the
Offer or Plan, as applicable, and to vote for or consent to such Superior Offer.
Each of the Company and the Holders agree to inform the other upon its receipt
of any proposal, expression of interest or request for information from any
person relating to an Alternative Offer and to deliver to the other any and all
written materials received by such person in connection therewith. In addition,
nothing contained herein shall be deemed to restrict the sale or transfer by any
Holder of any of


                                       3
<Page>


its Old Notes; provided, that the purchaser thereof shall be bound by the terms
of this Agreement, including this Section 1.02.

      (b) So long as this Agreement has not been terminated: (a) the Holders
will (i) not file a notice of default, acceleration or sale or take any other
action to collect on the Old Notes, including, without limitation, instructing
the Trustee on how to proceed in the exercise of any and all remedies, or (ii)
give instructions to the Trustee, if and when reasonably appropriate in their
determination and in such form as they in their discretion deem appropriate, to
desist from taking action that is inconsistent with this Agreement or the
Offer; so long as (x) no indemnity by such Holders is required in connection
with such action or notice and (y) the Holders, in their reasonable judgment,
determine that they would not be subject to any liability in connection with
their taking of any such action or giving of such notice; and (b) each of the
Holders will not, directly or indirectly, sell, assign, transfer, hypothecate
or otherwise dispose of (i) any Old Notes beneficially owned by it or as to
which it has investment authority or discretion (including Old Notes acquired
after the date hereof), (ii) any claim (as that term is defined in section
101(5) of the Bankruptcy Code) arising from, based on or related to the Old
Notes, or (iii) any option, interest in, or right to acquire any Old Notes or
claim referred to in clauses (i) and (ii) above, unless the transferee thereof
agrees in writing for the benefit of the other parties hereto to be bound by
all of the terms of this Agreement and executes a counterpart signature page of
this Agreement and the transferor provides the Company and the Holders with a
copy thereof, in which event each party shall be deemed to have acknowledged
that its obligations to the Holders hereunder shall be deemed to constitute
obligations in favor of such transferee.

      1.03 COMPANY BOARD REPRESENTATION; SECTION 14(F). (a) The Company and the
Holders shall use their commercially reasonable efforts to (i) cause each of
the directors (except the Company's chief executive officer) to resign from the
Board of Directors, effective as of the Consummation Date or Effective Date, as
applicable, and (ii) take all actions necessary to cause the Board of Directors
to consist of seven persons, one of whom shall be the Company's chief executive
officer, one of whom shall be selected by the existing Board of Directors and
five of whom shall be selected by the Holders, and in connection therewith
shall accept the resignations of those incumbent directors designated by the
Company and cause the Holders' designees to be elected.

      (b) The Company's obligations to appoint the Holders' designees to the
Board of Directors shall be subject to Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder, if applicable. The Company shall promptly
take all actions required pursuant to such Section and Rule in order to fulfill
its obligations under this Section. In addition the Company shall include in
the Offer Documents or the Plan (and any related disclosure statement), such
information with respect to the Company and its officers and directors as is
required under applicable law. The Holders shall supply to the Company and be
solely responsible for any information with respect to either of them and their
designees, officers, directors and affiliates provided for inclusion in any
such materials.

      1.04 CONDITIONS TO HOLDERS' OBLIGATIONS. The obligation of each Holder to
tender the Old Notes owned beneficially and of record by it in the Offer or
pursuant to the Plan, or to vote in favor of the Indenture Amendment, the Offer
or the Plan is subject to the fulfillment of


                                       4

                            COVENANTS OF THE COMPANY

            4.01 CONDUCT OF BUSINESS. Except as contemplated by this Agreement,
between the date hereof and the Consummation Date or the Confirmation, as
applicable, the Company and its subsidiaries shall conduct business only in the
ordinary course.

            4.02 ISSUANCE OF SECURITIES. Except as contemplated by this
Agreement, between the date hereof and the Consummation Date or the Confirmation
Date, as applicable, the Company shall not issue or agree to issue any
securities of the Company or enter into any Stock-Related Agreements other than

of the date hereof.


                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

            5.01 CHARTER AMENDMENT. The Company shall, through the Board of
Directors, as soon as reasonably practicable after the Consummation Date, duly
call, give notice of, convene and hold a meeting of its stockholders for the
purpose of voting on an amendment to its Certificate of Incorporation to
increase the number of authorized shares of Company Common Stock to 250 million
and to eliminate the Restricted Voting Common Stock and provide for the
conversion of the outstanding Restricted Voting Common Stock into Company Common
Stock on a share-for-share basis, subject to adjustment for any reverse split of
the Company Common Stock. As an alternative to increasing the number of shares
of authorized Company Common Stock at the stockholder meeting contemplated by
this SECTION 5.01, the Company may at such meeting seek stockholder approval of
a one for [30] reverse stock split, it being the intention of the parties that
there be sufficient authorized shares of common stock to permit the holders of
the New Stock shall have the ability to convert their shares of New Stock into
Company Common Stock following the stockholder meeting.

            5.02 COMPANY STOCK PLAN. Effective as of the Consummation Date or
Confirmation Date, as applicable, the Company shall adopt a long-term incentive
plan having such terms and conditions as may be mutually acceptable to the
Company and the Holders and covering a total of 12.5% of the shares of New Stock
outstanding immediately following the consummation of the Offer or Plan (the
"COMPANY STOCK PLAN"). Grants of awards under the Company Stock Plan shall be
made as contemplated by Schedule A attached hereto.

            5.03 EXPENSES. Except for the reasonable out-of-pocket expenses
incurred by the Holders in connection with the negotiation, execution and
implementation of this Agreement, including the reasonable fees, expenses and
disbursements of one counsel for the Holders, which the Company agrees to
reimburse to the Holders, whether or not the Offer or Plan is consummated, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such cost
or expense.

            6.03 AMENDMENT. This Agreement may be amended, supplemented or
modified by action taken by or on behalf of the Company and the Holders. No such
