Offer to Purchase) is cash, and in view of the amount of consideration payable

tender or hold Shares pursuant to the Offer.

To the Holders of Shares of
Vertex Communications Corporation:

                                  INTRODUCTION

    Signal Acquisition Corporation, a Texas corporation (the "Purchaser") and a
wholly owned subsidiary of TriPoint Global Communications Inc., a Delaware
corporation ("Parent"), hereby offers to purchase all outstanding shares of
Common Stock (the "Common Stock"), par value $.10 per share (the "Shares"), of
Vertex Communications Corporation, a Texas corporation (the "Company"), at
$22.00 per Share (the "Offer Price"), net to the seller in cash, without
interest thereon, upon the terms and subject to the conditions set forth in this
Offer to Purchase and in the related Letter of Transmittal (which, together with
any amendments or supplements hereto or thereto, collectively constitute the
"Offer").

    The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of November 11, 1999 (the "Merger Agreement"), among Parent, the Purchaser
and the Company pursuant to which, as soon as practicable following the
consummation of the Offer and the satisfaction or waiver of certain conditions,
the Purchaser will be merged with and into the Company (the "Merger"), with the
Company surviving the Merger as a wholly owned subsidiary of Parent (the
"Surviving Corporation"). At the effective time of the Merger (the "Effective
Time"), each outstanding Share (other than Shares held by shareholders who
perfect their dissent rights under Texas law, Shares owned by the Company as
treasury stock, and Shares owned by Parent or any direct or any indirect wholly
owned subsidiary of Parent or of the Company) will be converted into the right
to receive the Offer Price in cash (the "Per Share Merger Consideration"),
without interest thereon. The Merger Agreement provides that the Purchaser may
assign any or all of its rights and obligations (including the right to purchase
Shares in the Offer) to Parent or any wholly-owned subsidiary of Parent, but no
such assignment shall relieve the Purchaser of its obligations under the Merger
Agreement. The Merger is subject to a number of conditions, including the
approval of the Merger Agreement by shareholders of the Company (the "Company
Shareholder Approval") if required by applicable law. In the event the Purchaser
acquires 90% or more of the outstanding Shares pursuant to the Offer or
otherwise, the Purchaser would be able to effect the Merger pursuant to the
short-form merger provisions of the Texas Business Corporation Act (the "TBCA"),
without prior notice to, or any action by, any other shareholder of the Company.
In such event, the Purchaser could, and intends to, effect the Merger without
prior notice to, or any action by, any other shareholder of the Company. See
Section 12.

    Simultaneously with entering into the Merger Agreement, Parent and the
Purchaser entered into a Company Shareholder Agreement (the "Shareholder
Agreement") with each member of the Board of Directors of the Company (the
"Board") and William L. Anton (collectively the "Principal Shareholders"),
pursuant to which each Principal Shareholder has agreed, among other things, to
tender all the Shares that he beneficially owns (including Shares issuable upon
the exercise of Company Stock Options (as defined below)) at a price per Share
equal to the Offer Price. If the Principal Shareholders fail to tender their
Shares pursuant to the Offer, or withdraw their Shares prior to expiration of
the Offer, Parent will have the option to purchase such Shares at the Offer
Price following consummation of the Offer. The Principal Shareholders
collectively own approximately 13.1% of all outstanding Shares (assuming the
exercise of all Company Stock Options held by the Principal Shareholders).

    Tendering shareholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer.
Shareholders who hold their Shares through their broker or bank should consult
with such institution as to whether there are any fees applicable to a tender of
Shares. Parent will pay all fees and expenses of First Union Securities, Inc.,
which is acting as Dealer Manager (the "Dealer Manager" or "First Union
Securities"), First Union National Bank, which is acting as the Depositary (the
"Depositary"), and D.F. King & Co., Inc., which is acting as Information Agent
(the "Information Agent"), incurred in connection with the Offer. See
Section 16.

                                       1

    The Board has unanimously approved the Offer and the Merger and determined
that the terms of the Offer and the Merger are fair to, and in the best
interests of, the Company's shareholders and unanimously recommends that the
Company's shareholders accept the Offer and tender their Shares pursuant to the
Offer. The factors considered by the Board in arriving at its decision to
approve the Offer and the Merger and to recommend that shareholders of the
Company accept the Offer and tender their Shares are described in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which also is being mailed to shareholders of the Company.

    The Company's financial advisor, Frost Securities, Inc. ("Frost
Securities"), has delivered its opinion to the Board dated November 11, 1999
that, as of such date, and subject to the conditions and limitations set forth
therein, the consideration to be received by holders of Shares in the Offer and
the Merger is fair, from a financial point of view. Such opinion is set forth in
full as an exhibit to the Schedule 14D-9.

    The Offer is conditioned upon, among other things, (a) there being validly
tendered and not withdrawn prior to the expiration of the Offer that number of
Shares which would represent at least a majority of all outstanding Shares on a
fully diluted basis (the "Minimum Tender Condition"), (b) any waiting periods
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), applicable to the purchase of Shares pursuant to the Offer having
expired or been terminated (the "HSR Act Condition") and (c) the period of time
for any applicable review process by the Committee on Foreign Investment in the
United States ("CFIUS") under Section 721(a) of the Defense Production Act of
1950, as amended (the "Exon-Florio Act") having expired and CFIUS not having
taken any action or made any recommendation to the President of the United
States to block or to prevent consummation of the Offer or the Merger (the
"Exon-Florio Act Condition"). The Purchaser reserves the right (subject to the
applicable rules and regulations of the Securities and Exchange Commission (the
"SEC")) to waive or reduce the Minimum Tender Condition and to elect to
purchase, pursuant to the Offer, fewer than the minimum number of Shares
necessary to satisfy the Minimum Tender Condition in the event that either
(a) the Company provides the Purchaser with prior written consent to do so or
(b) the failure of the Minimum Tender Condition to be satisfied results from the
failure of the Principal Shareholders to validly tender their Shares prior to
the expiration of the Offer or from the withdrawal of any of their Shares prior
to the expiration of the Offer. As used herein, Shares on a fully diluted basis
means all outstanding securities entitled generally to vote in the election of
directors of the Company on a fully diluted basis, after giving effect to the
exercise or conversion of all options, rights and securities exercisable or
convertible into such voting securities. See Sections 1 and 14.

    The Company has informed the Purchaser that, as of November 11, 1999, there
were 5,116,314 Shares outstanding and 702,727 Shares authorized for issuance
pursuant to the exercise of outstanding options to purchase Shares ("Company
Stock Options"). As a result, as of such date, the Minimum Tender Condition
would be satisfied if the Purchaser acquired 2,909,521 Shares.

    Certain Federal income tax consequences of the sale of Shares pursuant to
the Offer are described in Section 5.

    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

                                THE TENDER OFFER

1. TERMS OF THE OFFER

    Upon the terms and subject to the conditions of the Offer, the Purchaser
will accept for payment and pay for all Shares validly tendered, including
Shares issuable upon exercise of Company Stock Options (the "Option Shares")
prior to the Expiration Date and not theretofore withdrawn in accordance with
Section 3. The term "Expiration Date" means 12:00 Midnight, New York City time,
on Thursday, December 16, 1999, unless and until the Purchaser shall have
extended the period of time during which the Offer is open, in which event the
term "Expiration Date" shall mean the latest time and date at which the Offer,
as so extended by the Purchaser, will expire.

    The Purchaser expressly reserves the right to modify the terms of the Offer,
except that without the consent of the Company, the Purchaser shall not
(a) reduce the number of Shares to be subject to the Offer, (b) reduce the Offer
Price, (c) modify or add to the conditions to the Offer, (d) waive the Minimum
Tender Condition (unless the failure of the Minimum Tender Condition to be
satisfied results from the failure of the Principal Shareholders to validly
tender their Shares pursuant to the Offer, or from the withdrawal of such
Shares) or amend the Offer in any manner materially adverse to the holders of
Shares or (e) except as provided in the next paragraph, extend the Offer if all
the conditions to the Offer have been satisfied.

    Notwithstanding the foregoing, the Purchaser may, without the consent of the
Company, (a) if at the scheduled initial or any extended expiration date
(whether extended pursuant to this clause (a) or otherwise) of the Offer any of
the conditions to the Offer shall not have been satisfied or waived, extend the
Offer for up to five business days from such scheduled initial or extended
expiration date, (b) extend the Offer for any period required by any rule,
regulation, interpretation or position of the SEC or the staff thereof
applicable to the Offer, (c) if at the scheduled initial or any extended
expiration date of the Offer all the conditions to the Offer are satisfied and
more than 70% but less than 90% of the outstanding Shares on a fully diluted
basis have been validly tendered and not withdrawn in the Offer, extend the
Offer up to a maximum of 10 additional business days in the aggregate beyond the
latest expiration date that would otherwise be permitted under clause (a) or
(b) of this sentence and (d) extend the Offer for any reason for a period of not
more than three business days beyond the latest expiration date that would
otherwise be permitted under clause (a), (b) or (c) of this sentence.

    Subject to the terms of the Merger Agreement and applicable rules and
regulations of the SEC, the Purchaser reserves the right, in its sole
discretion, at any time and from time to time, and regardless of whether or not
any of the events or facts set forth in Section 14 hereof shall have occurred,
to (a) extend the period of time during which the Offer is open and thereby
delay acceptance for payment of and the payment for any Shares, by giving oral
or written notice of such extension to the Depositary and (b) except as set
forth above, amend the Offer in any other respect by giving oral or written
notice of such amendment to the Depositary. Under no circumstances will interest
be paid on the purchase price for tendered Shares, whether or not the Purchaser
exercises its right to extend the Offer.

    If by 12:00 Midnight, New York City time, on Thursday, December 16, 1999 (or
any date or time then set as the Expiration Date), any of or all of the
conditions to the Offer have not been satisfied or waived, the Purchaser
reserves the right (but shall not be obligated), subject to the terms and
conditions contained in the Merger Agreement and to the applicable rules and
regulations of the SEC, to (a) terminate the Offer and not accept for payment or
pay for any Shares and return all tendered Shares to tendering shareholders,
(b) except as set forth above with respect to the Minimum Tender Condition,
waive all the unsatisfied conditions and accept for payment and pay for all
Shares validly tendered prior to the Expiration Date and not theretofore
withdrawn, (c) extend the Offer and, subject to the right of shareholders to
withdraw Shares until the Expiration Date, retain the Shares that have been
tendered during the period or periods for which the Offer is extended or
(d) amend the Offer.

                                       3
<PAGE>
    There can be no assurance that the Purchaser will exercise its right to
extend the Offer. Any extension, amendment or termination will be followed as
promptly as practicable by public announcement in accordance with the
announcement requirements of Rule 14d-4(c) under the Securities Exchange Act of
1934, as amended (the "Exchange Act"). In the case of an extension,
Rule 14e-1(d) under the Exchange Act requires that the announcement be issued no
later than 9:00 a.m., New York City time on the next business day after the
previously schedule Expiration Date. Subject to applicable law (including
Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require that any
material change in the information published, sent or given to shareholders in
connection with the Offer be promptly disseminated to shareholders in a manner
reasonably designed to inform shareholders of such change), and without limiting
the manner in which the Purchaser may choose to make any public announcement,
the Purchaser will not have any obligation to publish, advertise or otherwise
communicate any such public announcement other than by making a release to the
Dow Jones News Service.

    If the Purchaser extends the Offer or if the Purchaser is delayed in its
acceptance for payment of Shares (whether before or after its acceptance for
payment of Shares) or it is unable to accept for payment or pay for Shares
pursuant to the Offer for any reason, then, without prejudice to the Purchaser's
rights under the Offer (but subject to compliance with the terms of the Merger
Agreement and Rule 14e-1(c) under the Exchange Act, which requires that a tender
offeror pay the consideration offered or return the tendered securities promptly
after termination or withdrawal of a tender offer), the Depositary may
nevertheless, on behalf of the Purchaser, retain tendered Shares, and such
Shares may not be withdrawn except to the extent tendering shareholders are
entitled to exercise, and duly exercise, withdrawal rights as described in
Section 3.

    If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including a waiver of the Minimum Tender Condition), the Purchaser will
disseminate additional tender offer materials and extend the Offer to the extent
required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. The
minimum period during which the Offer must remain open following material
changes in the terms of the Offer or information concerning the Offer, other
than a change in price or a change in the percentage of securities sought, would
depend upon the facts and circumstances then existing, including the relative
materiality of the changed terms or information. With respect to a change in
price or a change in the percentage of securities sought, a minimum period of 10
business days is generally required to allow for adequate dissemination to
shareholders.

    The Company has provided or will provide the Purchaser with the Company's
shareholder list and security position listing for the purpose of disseminating
the Offer to holders of Shares. This Offer to Purchase, the related Letter of
Transmittal and other relevant materials will be mailed by the Purchaser to
record holders of Shares and will be furnished to brokers, dealers, banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the Company's shareholder list, or, if applicable, who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Shares.

2. PROCEDURE FOR TENDERING SHARES

    VALID TENDER.  For a shareholder validly to tender Shares (including Option
Shares) pursuant to the Offer, either (a) a properly completed and duly executed
Letter of Transmittal (or a facsimile thereof), together with any required
signature guarantees and any other required documents, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Date and, except in the case of Option Shares,
either certificates for tendered Shares must be received by the Depositary at
one of such addresses or such Shares must be delivered pursuant to the
procedures for book-entry transfer set forth below (and a confirmation of such
delivery, including an Agent's Message (as defined below), must be received by
the Depositary), in each case prior to the

                                       4
<PAGE>
Expiration Date or (b) the tendering shareholder must comply with the guaranteed
delivery procedures set forth below.

    The Depositary will establish accounts with respect to the Shares at The
Depository Trust Company (the "Book-Entry Transfer Facility") for purposes of
the Offer within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Shares by causing the Book-
Entry Transfer Facility to transfer such Shares into the Depositary's account in
accordance with the Book-Entry Transfer Facility's procedures for such transfer.
However, although delivery of Shares may be effected through book- entry
transfer into the Depositary's account at the Book-Entry Transfer Facility, the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, with any required signature guarantees, or an Agent's Message, and any
other required documents, must, in any case, be transmitted to, and received by,
the Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase prior to the Expiration Date, or the tendering shareholder must
comply with the guaranteed delivery procedures described below. The confirmation
of a book-entry transfer of Shares into the Depositary's account at the
Book-Entry Transfer Facility as described above is referred to herein as a
"Book-Entry Confirmation." Delivery of documents to the Book-Entry Transfer
Facility in accordance with the Book-Entry Transfer Facility's procedures does
not constitute delivery to the Depositary.

    The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

    The method of delivery of Shares, the Letter of Transmittal and all other
required documents, including delivery through the Book-Entry Transfer Facility,
is at the election and risk of the tendering shareholder. Shares will be deemed
delivered only when actually received by the Depositary (including, in the case
of a book-entry transfer, by Book-Entry Confirmation). If delivery is by mail,
registered mail with return receipt requested, properly insured, is recommended.
In all cases, sufficient time should be allowed to ensure timely delivery.

    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal (a) if the Letter of Transmittal is signed by the registered
holder(s) of Shares (which term, for purposes of this Section, includes any
participant in any of the Book-Entry Transfer Facility's systems whose name
appears on a security position listing as the owner of the Shares) tendered
therewith and such registered holder has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal or (b) if such Shares are tendered
for the account of a firm that is a participant in the Security Transfer Agents
Medallion Program or the New York Stock Exchange Guarantee Program or the Stock
Exchange Medallion Program or by any other "eligible guarantor institution", as
such term is defined in Rule 17Ad-15 under the Exchange Act (each, an "Eligible
Institution"). In all other cases, all signatures on the Letter of Transmittal
must be guaranteed by an Eligible Institution. See Instructions 1 and 5 to the
Letter of Transmittal. If the certificates for Shares are registered in the name
of a person other than the signer of the Letter of Transmittal, or if payment is
to be made or certificates for Shares not tendered or not accepted for payment
are to be returned to a person other than the registered holder of the
certificates surrendered, the tendered certificates must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered holders or owners appear on the certificates,
with the signatures on the certificates or stock powers guaranteed in the manner
described above. See Instructions 1 and 5 to the Letter of Transmittal.

    GUARANTEED DELIVERY.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates for Shares are not immediately
available or the procedure for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the

                                       5
<PAGE>
Depositary prior to the Expiration Date, such shareholder's tender may be
effected if all the following conditions are met:

    (i) such tender is made by or through an Eligible Institution;

    (ii) a properly completed and duly executed Notice of Guaranteed Delivery,
         substantially in the form provided by the Purchaser, is received by the
         Depositary, as provided below, prior to the Expiration Date; and

   (iii) the certificates for all tendered Shares, in proper form for transfer
         (or a Book-Entry Confirmation with respect to all such Shares),
         together with a properly completed and duly executed Letter of
         Transmittal (or a facsimile thereof), with any required signature
         guarantees, or, in the case of a book-entry transfer, an Agent's
         Message, and any other required documents are received by the
         Depositary within three trading days after the date of execution of
         such Notice of Guaranteed Delivery. A "trading day" is any day on which
         the New York Stock Exchange (the "NYSE") is open for business.

    The Notice of Guaranteed Delivery may be delivered by hand to the Depositary
or transmitted by telegram, facsimile transmission or mail to the Depositary and
must include a guarantee by an Eligible Institution in the form set forth in
such Notice of Guaranteed Delivery.

    Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (a) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (b) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, and (c) any other documents required by the Letter of Transmittal.
Accordingly, tendering shareholders may be paid at different times depending
upon when certificates for Shares or Book-Entry Confirmations with respect to
such Shares are actually received by the Depositary. Under no circumstances will
any interest be paid on the purchase price of the Shares, regardless of any
extension of the Offer or any delay in making such payment.

    The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering shareholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

    APPOINTMENT.  By executing a Letter of Transmittal as set forth above, the
tendering shareholder will irrevocably appoint designees of the Purchaser as
such shareholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of such shareholder's rights with respect to the Shares tendered by such
shareholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after November 11, 1999. All such proxies will be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such shareholder as provided herein. Upon such
appointment, all prior powers of attorney, proxies and consents given by such
shareholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given (and, if given, will not be deemed
effective). The designees of the Purchaser will thereby be empowered to exercise
all voting and other rights with respect to such Shares and other securities or
rights in respect of any annual, special or adjourned meeting of the Company's
shareholders, actions by written consent in lieu of any such meeting or
otherwise, as they in their sole discretion deem proper. The Purchaser reserves
the right to require that, in order for Shares to be deemed validly tendered,
immediately upon the Purchaser's acceptance for payment of such Shares, the
Purchaser must be able to exercise full voting, consent and other rights with
respect to such Shares and other securities or rights, including voting at any
meeting of shareholders.

<PAGE>
    TENDER OF SHARES ISSUABLE UPON EXERCISE OF COMPANY STOCK OPTIONS.  Holders
of Company Stock Options who wish to tender Shares for which their Company Stock
Options are exercisable may do so either (a) by first exercising their Company
Stock Options and delivering to the Depositary certificates for Shares being so
tendered or (b) by executing a Letter of Transmittal appointing the Depositary
as their agent to exercise if, and only if, the Offer is consummated, their
Company Stock Options for the number of Option Shares to be tendered indicated
in the Letter of Transmittal. In the case of clause (b), only a number of whole
Option Shares may be tendered. The Depositary will, in the event the Offer is
consummated, pay to the Company for each Option Share tendered pursuant to
clause (b) an amount equal to the exercise price of the related exercised
Company Stock Option, and pay to the holder of the Company Stock Option tendered
pursuant to clause (b) for each such Option Share tendered an amount equal to
the Offer Price minus the exercise price of the exercised Company Stock Option.
The amount paid to employees pursuant to clause (b) will be reduced by the
amount of any wage and employment withholding taxes required to be deducted and
withheld under the Internal Revenue Code of 1986, as amended, or under any
provision of state, local or foreign law. In any event, such payments for Option
Shares tendered upon exercise of such Company Stock Options that are accepted
for payment pursuant to the Offer will only be made after the receipt by the
Depositary of such Option Shares as described in Section 4. Holders of Company
Stock Options who elect to tender Option Shares pursuant to clause (b) above by
executing a Letter of Transmittal, in addition to the matters described under
"Appointment" above, will irrevocably appoint the Depositary as such holder's
agent and attorney-in-fact in the manner set forth in the Letter of Transmittal,
with full power of substitution, to the full extent of such holder's rights, to
exercise the Company Stock Options for the Option Shares being tendered. Such
appointment will be effective when, and only to the extent that, the Purchaser
accepts for payment Option Shares tendered by a holder of Company Stock Options.

    DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser in its sole discretion, which determination
will be final and binding. The Purchaser reserves the absolute right to reject
any or all tenders determined by it not to be in proper form or the acceptance
for payment of or payment for which may, in the opinion of the Purchaser's
counsel, be unlawful. The Purchaser also reserves the absolute right to waive
any defect or irregularity in the tender of any Shares of any particular
shareholder whether or not similar defects or irregularities are waived in the
case of other shareholders. No tender of Shares will be deemed to have been
validly made until all defects or irregularities relating thereto have been
cured or waived. None of the Purchaser, Parent, the Depositary, the Information
Agent, the Dealer Manager or any other person will be under any duty to give
notification of any defects or irregularities in tenders or incur any liability
for failure to give any such notification. The Purchaser's interpretation of the
terms and conditions of the Offer (including the Letter of Transmittal and the
instructions thereto) will be final and binding.

    BACKUP WITHHOLDING.  In order to avoid "backup withholding" of Federal
income tax on payments of cash pursuant to the Offer, a shareholder surrendering
Shares in the Offer must, unless an exemption applies, provide the Depositary
with such shareholder's correct taxpayer identification number ("TIN") on a
Substitute Form W-9 and certify under penalties of perjury that such TIN is
correct and that such shareholder is not subject to backup withholding. If a
shareholder does not provide such shareholder's correct TIN or fails to provide
the certifications described above, the Internal Revenue Service (the "IRS") may
impose a $50 penalty on such shareholder and payment of cash to such shareholder
pursuant to the Offer may be subject to backup withholding of 31%. All
shareholders surrendering Shares pursuant to the Offer should complete and sign
the Substitute Form W-9 included as part of the Letter of Transmittal to provide
the information and certification necessary to avoid backup withholding (unless
an applicable exemption exists and is proved in a manner satisfactory to the
Purchaser and the Depositary). Certain shareholders (including, among others,
all corporations and certain foreign individuals and entities) are not subject
to backup withholding. Noncorporate foreign shareholders should complete and
sign a Form W-8, Certificate of Foreign Status, or a Form W-8BEN, Certificate of
Foreign Status of Beneficial Owner for United States Withholding, copies of
which may be obtained from the Depositary, in order to avoid backup withholding.
See Instruction 9 to the Letter of Transmittal.

3. WITHDRAWAL RIGHTS

    Except as otherwise provided in this Section 3, tenders of Shares are
irrevocable. Shares tendered pursuant to the Offer may be withdrawn pursuant to
the procedures set forth below at any time prior to the Expiration Date and,
unless theretofore accepted for payment and paid for by the Purchaser pursuant
to the Offer, may also be withdrawn at any time after Sunday, January 16, 2000.

    For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase and
must specify the name of the person having tendered the Shares to be withdrawn
(or in the case of holders tendering Shares issuable upon the exercise of
Company Stock Options, the name of the registered holder of the Company Stock
Options that have been tendered for the Shares to be withdrawn), the number of
Shares to be withdrawn and the name of the registered holder of the Shares to be
withdrawn, if different from the name of the person who tendered the Shares. If
certificates for Shares have been delivered or otherwise identified to the
Depositary, then, prior to the physical release of such certificates, the serial
numbers shown on such certificates must be submitted to the Depositary and,
unless such Shares have been tendered by an Eligible Institution, the signatures
on the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been delivered pursuant to the procedure for book-entry transfer as
set forth in Section 2, any notice of withdrawal must also specify the name and
number of the account at the Book-Entry Transfer Facility to be credited with
the withdrawn Shares and otherwise comply with the Book-Entry Transfer
Facility's procedures. Withdrawals of tenders of Shares may not be rescinded,
and any Shares properly withdrawn will thereafter be deemed not validly tendered
for purposes of the Offer. However, withdrawn Shares may be retendered by again
following one of the procedures described in Section 2 at any time prior to the
Expiration Date.

    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Parent, the Depositary, the Information Agent, the Dealer Manager or
any other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

4. ACCEPTANCE FOR PAYMENT AND PAYMENT

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will accept for payment and will pay for all Shares
validly tendered prior to the Expiration Date, and not properly withdrawn in
accordance with Section 3, promptly after the Expiration Date. All questions as
to the satisfaction of such terms and conditions will be determined by the
Purchaser in its reasonable discretion, which determination will be final and
binding. See Sections 1 and 14. The Purchaser expressly reserves the right, in
its reasonable discretion, to delay acceptance for payment of or payment for
Shares in order to comply in whole or in part with any applicable law,
including, without limitation, the HSR Act and the Exon-Florio Act. Any such
delays will be effected in compliance with Rule 14e-1(c) under the Exchange Act,
which requires that a tender offeror pay the consideration offered or return the
tendered securities promptly after termination or withdrawal of a tender offer.

    Thyssen-Bornemisza Continuity Trust (the "Trust"), which ultimately controls
Parent, has filed a Notification and Report Form with respect to the Offer under
the HSR Act. The waiting period under the HSR Act with respect to the Offer will
expire at 11:59 p.m., New York City time, on Tuesday, November 30, 1999, the
15th day after the day such form was filed, unless early termination of the
waiting period is granted. However, the Antitrust Division of the Department of
Justice (the "Antitrust Division") or the Federal Trade Commission (the "FTC")
may extend the waiting period by requesting additional information or
documentary material from the Trust. If such a request is made, such waiting
period will expire at 11:59 p.m., New York City time, on the 10th day after
substantial compliance by the Trust with such request. See Section 15.

                                       8
<PAGE>
    The Purchaser and the Company have made a filing under the Exon-Florio Act.
The time period for CFIUS to determine whether to undertake an investigation
will expire on Wednesday, December 15, 1999, the 30th day following the
acceptance of such filing by CFIUS. In the event that CFIUS determines to
undertake an investigation, such investigation must be completed within
forty-five days after such determination. The President has fifteen days
following the presentation by CFIUS of its recommendation to the President in
which to suspend or prohibit the proposed acquisition or seek other appropriate
relief. See Section 15.

    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (a) certificates for
(or a timely Book-Entry Confirmation with respect to) such Shares, (b) a Letter
of Transmittal (or a facsimile thereof), properly completed and duly executed,
with any required signature guarantees, or, in the case of a book- entry
transfer, an Agent's Message, and (c) any other documents required by the Letter
of Transmittal. The per Share consideration paid to any shareholder pursuant to
the Offer will be the highest per Share consideration paid to any other holder
of Shares pursuant to the Offer.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn as, if and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Shares (which will
include all Shares received and Option Shares tendered upon the exercise of
Company Stock Options exercised at such time). Payment for Shares accepted for
payment pursuant to the Offer will be made by deposit of the purchase price
therefor with the Depositary, which will act as agent for tendering shareholders
for the purpose of receiving payment from the Purchaser and transmitting payment
to tendering shareholders. Under no circumstances will interest be paid on the
purchase price of any Shares to be paid by the Purchaser, regardless of any
extension of the Offer or any delay in making such payment.

    If the Purchaser extends the Offer or if the Purchaser is delayed in its
acceptance for payment of or payment for Shares (whether before or after its
acceptance for payment of Shares) or it is unable to accept for payment or pay
for Shares pursuant to the Offer for any reason, then, without prejudice to the
Purchaser's rights under the Offer (but subject to compliance with the terms of
the Merger Agreement and Rule 14e-1(c) under the Exchange Act, which requires
that a tender offeror pay the consideration offered or return the tendered
securities promptly after termination or withdrawal of a tender offer), the
Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent tendering
shareholders are entitled to exercise, and duly exercise, withdrawal rights as
described in Section 3.

    If any tendered Shares are not purchased pursuant to the Offer for any
reason, certificates for any such Shares will be returned without expense to the
tendering shareholder (or, in the case of Shares delivered by book-entry
transfer of such Shares into the Depositary's account at a Book-Entry Transfer
Facility pursuant to the procedure set forth in Section 2, such Shares will be
credited to an account maintained at the appropriate Book-Entry Transfer
Facility) as promptly as practicable after the expiration or termination of the
Offer.

    The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Parent, or to any wholly-owned subsidiary of Parent,
the right to purchase Shares tendered pursuant to the Offer, but any such
transfer or assignment will not relieve the Purchaser of its obligations under
the Offer and will in no way prejudice the rights of tendering shareholders to
receive payment for Shares validly tendered and accepted for payment pursuant to
the Offer.

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The following is a general discussion of certain United States Federal
income tax consequences of the receipt of cash by a holder of Shares pursuant to
the Offer or the Merger. Except as specifically noted, this discussion applies
only to a U.S. Holder.

                                       9
<PAGE>
    A "U.S. Holder" means a holder of Shares that is (i) a citizen or resident
of the United States, (ii) a corporation or other entity taxable as a
corporation created or organized in or under the laws of the United States or
any political subdivision thereof or therein or (iii) an estate or trust, the
income of which is subject to United States Federal income taxation regardless
of its source. A "Non-U.S. Holder" is a holder of Shares that is not a U.S.
Holder.

    The receipt of cash for Shares pursuant to the Offer or the Merger will be a
taxable transaction for Federal income tax purposes under the Internal Revenue
Code of 1986, as amended (the "Code"), and may also be a taxable transaction
under applicable state, local or foreign income or other tax laws. Generally,
for Federal income tax purposes, a U.S. Holder will recognize gain or loss equal
to the difference between the amount of cash received by the U.S. Holder
pursuant to the Offer or the Merger and the aggregate tax basis in the Shares
purchased pursuant to the Offer (or canceled pursuant to the Merger). Gain or
loss will be calculated separately for each block of Shares purchased pursuant
to the Offer (or canceled pursuant to the Merger).

    Gain (or loss) will be capital gain (or loss), assuming that such Shares are
held as a capital asset. Capital gains of individuals, estates and trusts
generally are subject to a maximum Federal income tax rate of (i) 39.6% if, at
the time the Purchaser accepts the Shares for payment (or the Shares are
canceled pursuant to the Merger) the shareholder held the Shares for not more
than one year and (ii) 20% if the shareholder held such Shares for more than one
year at such time. Capital gains of corporations generally are taxed at the
Federal income tax rates applicable to corporate ordinary income. In addition,
under present law, the ability to use capital losses to offset ordinary income
is limited.

    A shareholder that tenders Shares pursuant to the Offer or surrenders Shares
pursuant to the Merger may be subject to 31% backup withholding unless the
shareholder provides its TIN and certifies, under penalties of perjury, that
such number is correct (or properly certifies that it is awaiting a TIN) and
that such shareholder is not subject to backup withholding, or unless an
exemption applies. A shareholder that does not furnish its TIN may be subject to
a penalty imposed by the IRS. See "--Backup Withholding" under Section 2.

    If backup withholding applies to a shareholder, the Depositary is required
to withhold 31% from payments to such shareholder. Backup withholding is not an
additional tax. Rather, the amount of the backup withholding can be credited
against the Federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the shareholder upon filing an income tax return.

    The foregoing discussion is not applicable with respect to Shares received
pursuant to the exercise of Company Stock Options or otherwise as compensation.
It may not be applicable with respect to holders of Shares who are subject to
special tax treatment under the Code, such as Non-U.S. Holders, life insurance
companies, tax-exempt organizations, financial institutions, dealers in
securities or currencies, persons who hold Shares as a position in a "straddle"
or as part of a "hedging" or "conversion" transaction and persons that have a
functional currency other than the U.S. dollar, and may not apply to a holder of
Shares in light of individual circumstances. Shareholders are urged to consult
their own tax advisors to determine the particular tax consequences to them
(including the application and effect of any state, local or foreign income and
other tax laws) of the Offer and the Merger.

6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES

    On November 11, 1999, the last full trading day before the first public
announcement of the execution of the Merger Agreement, the last reported sales
price of the Shares on the NYSE was $14.8125 per Share. The Offer Price of
$22.00 represents a 48.5% premium over this closing price. On November 17, 1999,
the last full trading day before the commencement of the Offer, the last
reported sales price of the Shares on the NYSE was $20.9375 per Share.

    The Purchaser has been advised by the Company that the Company has never
paid any cash dividends on the Shares.

    Shareholders are urged to obtain current market quotations for the Shares.

7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; CONTINUED LISTING ON THE
   NYSE; EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS

    MARKET FOR SHARES.  The purchase of Shares pursuant to the Offer will reduce
the number of holders of Shares and the number of Shares that might otherwise
trade publicly and could adversely affect the liquidity and market value of the
remaining Shares held by the public.

    CONTINUED LISTING ON THE NYSE.  Depending upon the number of Shares
purchased pursuant to the Offer, the Shares may no longer meet the requirements
of the NYSE for continued listing. According to the NYSE's published guidelines,
the NYSE would consider delisting the Shares if, among other things, the record
holders of at least 100 Shares were to fall below 1,200 and the average monthly
trading volume of the Shares were to fall below 100,000, or the number of
publicly held Shares (exclusive of management or other concentrated holdings)
were to fall below 600,000 and the aggregate market value of publicly held
Shares were to not exceed $8,000,000. According to the Company, as of
November 11, 1999, there were approximately 2,700 holders of record of Shares
and there were 5,116,314 Shares outstanding. If, as a result of the purchase of
Shares pursuant to the Offer or otherwise, the Shares no longer meet the
requirements of the NYSE for continued listing and the Shares are no longer
listed, the market for Shares would be adversely affected.

    In the event that the Shares no longer meet the requirements of the NYSE for
continued listing, it is possible that the Shares would continue to trade in the
over-the-counter market and that price quotations would be reported by other
sources. The extent of the public market for the Shares and the availability of
such quotations would, however, depend upon the number of holders of Shares
remaining at such time, the interest in maintaining a market in Shares on the
part of securities firms, the possible termination of registration of the Shares
under the Exchange Act, as described below, and other factors.

                                       11
<PAGE>
    EXCHANGE ACT REGISTRATION.  The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the SEC if the Shares are not
listed on a national securities exchange, quoted on an automated inter-dealer
quotation system or held by 300 or more holders of record. Termination of
registration of the Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to its shareholders and to
the SEC and would make certain provisions of the Exchange Act no longer
applicable to the Company, such as the short-swing profit recovery provisions of
Section 16(b) of the Exchange Act, the requirement of furnishing a proxy
statement pursuant to Section 14(a) of the Exchange Act in connection with
shareholders' meetings and the related requirement of furnishing an annual
report to shareholders and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 or 144A promulgated
under the Securities Act of 1933, as amended (the "Securities Act"), may be
impaired or eliminated. The Purchaser intends to seek to cause the Company to
apply for termination of registration of the Shares under the Exchange Act as
soon after the completion of the Offer as the requirements for such termination
are met.

    If public quotation and registration of the Shares is not terminated prior
to the Merger, then the Shares will no longer be quoted and the registration of
the Shares under the Exchange Act will be terminated following the consummation
of the Merger.

    MARGIN REGULATIONS.  The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of the Shares. Depending upon factors
similar to those described above regarding listing and market quotations, it is
possible that, following the Offer, the Shares would no longer constitute
"margin securities" for the purposes of the margin regulations of the Federal
Reserve Board and therefore could no longer be used as collateral for loans made
by brokers. In any event, the Shares will cease to be "margin securities" if
registration of the Shares under the Exchange Act is terminated.

    Except as otherwise stated in this Offer to Purchase, the information
concerning the Company contained herein has been taken from or based upon
publicly available documents on file with the SEC and other publicly available
information. Although the Purchaser and Parent do not have any knowledge that

failure by the Company to disclose events that may have occurred and may affect
the significance or accuracy of any such information.

    CERTAIN COMPANY PROJECTIONS. During the course of discussions between
representatives of Parent and the Company, the Company provided Parent or its
representatives with certain non-public business and financial information about
the Company. This information included a projected net income for the Company of
$4.2 million in fiscal year 2000.

    The Company has advised the Purchaser and Parent that it does not as a
matter of course make public any projections as to future performance or
earnings, and the projections set forth above are included in this Offer to
Purchase only because the information was provided to Parent. The projections
were not prepared with a view to public disclosure or compliance with the
published guidelines of the SEC or the guidelines established by the American
Institute of Certified Public Accountants regarding projections or forecasts.
The Company's internal operating projections are, in general, prepared solely
for internal use and capital budgeting and other management decisions and are
subjective in many respects and thus susceptible to various interpretations and
periodic revision based on actual experience and business developments. The
projections were based on a number of assumptions that are beyond the control of
the Company, the Purchaser or Parent or their respective financial advisors,
including economic forecasting (both general and specific to the Company's
business), which is inherently uncertain and subjective. None of the Purchaser
or Parent or their respective financial advisors assumes any responsibility for
the accuracy of any of the projections. The inclusion of the foregoing
projections should not be regarded as an indication that the Company, the
Purchaser or Parent or any other person who received such information considers
it an accurate prediction of future events. None of the Company, the Purchaser
or Parent intends to update, revise or correct such projections if they become
inaccurate (even in the short term).

9. CERTAIN INFORMATION CONCERNING THE PURCHASER, PARENT AND TBG HOLDINGS

    The Purchaser, a Texas corporation, was recently incorporated for the
purpose of acting as an acquisition vehicle. It has not conducted any unrelated
activities since its incorporation. The principal executive office of the
Purchaser is located at 565 Fifth Avenue, 17th Floor, New York, NY 10017. All
outstanding shares of common stock of Purchaser are owned by Parent.

    The principal executive office of Parent, a Delaware corporation, is located
at 565 Fifth Avenue, 17th Floor, New York, NY 10017. Parent is a leading global
supplier of satellite and wireless communications products and services for
video, voice and data. The company is comprised of three groups: RSI, Prodelin
and CSA Wireless Communications. RSI offers a full range of earth station and
base station communications products and services. Prodelin offers VSAT
satellite antennae. CSA Wireless Communications offers wireless antenna
products. TBG Holdings indirectly owns 80% of the outstanding shares of common
stock of Parent.

    The principal office of TBG Holdings, a Netherlands Antilles corporation, is
located at 17 Theaterstraat, Curacao, Netherlands Antilles. The principal
business of TBG Holdings is holding operating companies, management companies
and investment companies worldwide. Thyssen-Bornemisza Continuity Trust, a
Bermuda trust, is the sole shareholder of TBG Holdings and ultimately controls
Parent.

    The name, citizenship, business address, present principal occupation or
employment and five-year employment history of each of the directors and
executive officers of the Purchaser, Parent and TBG Holdings are set forth in
Schedule I hereto.

    TBG Holdings, through its subsidiaries Thybo Gamma Ltd. and Vulcan
Securities Limited, both Bermuda corporations, beneficially owns 157,100 Shares,
none of which were acquired during the past 60 days. Except as described in this
Offer to Purchase, none of the Purchaser, Parent or TBG Holdings (together, the
"Corporate Entities") or, to the best knowledge of the Corporate Entities, any
of the persons listed in Schedule I or any associate or majority-owned
subsidiary of the Corporate Entities or any of the persons so listed,
beneficially owns any equity security of the Company, and none of the Corporate
Entities or, to the best knowledge of the Corporate Entities, any of the other
persons referred to above, or

                                       14
<PAGE>
any of the respective directors, executive officers or subsidiaries of any of
the foregoing, has effected any transaction in any equity security of the
Company during the past 60 days. See Section 11.

    Except as described in this Offer to Purchase, (a) there have not been any
contacts, transactions or negotiations between the Corporate Entities, any of
their respective subsidiaries or, to the best knowledge of the Corporate
Entities, any of the persons listed in Schedule I, on the one hand and the
Company or any of its directors, officers or affiliates, on the other hand, that
are required to be disclosed pursuant to the rules and regulations of the SEC
and (b) none of the Corporate Entities or, to the best knowledge of the
Corporate Entities, any of the persons listed in Schedule I has any contract,
arrangement, understanding or relationship with any person with respect to any
securities of the Company.

    Because the only consideration in the Offer and Merger is cash and the Offer
covers all outstanding Shares, and in view of the absence of a financing
condition and the amount of consideration payable in relation to the financial
capability of Parent and its affiliates, the Purchaser believes the financial
condition of Parent and its affiliates is not material to a decision by a holder
of Shares whether to sell, tender or hold Shares pursuant to the Offer.

10. SOURCE AND AMOUNT OF FUNDS

    The Purchaser estimates that the amount of funds required to purchase all
outstanding Shares pursuant to the Offer, to pay cash to holders of Stock
Options pursuant to the Merger Agreement and to pay fees and expenses related to
the Offer will be approximately $129 million. The Purchaser will obtain such
funds directly or indirectly from Parent. Such funds will be obtained by Parent
from existing cash resources or from borrowings pursuant to the Credit Facility
dated as of June 25, 1998 (the "Credit Facility Agreement") among Parent,
certain of its subsidiaries, First Union National Bank and certain other
financial institutions. Parent expects that the Credit Facility Agreement will
be amended in connection with the Merger although the terms of such amendment
have not yet been negotiated.

11. CONTACTS AND TRANSACTIONS WITH THE COMPANY; BACKGROUND OF THE OFFER

    On January 8, 1997, Jack Haegele, the Chief Executive Officer and a director
of Parent, met with J. Rex Vardeman, Chairman of the Board, President and Chief
Executive Officer of the Company, in Kilgore, Texas to discuss a possible
acquisition of the Company by Parent. This meeting was followed by a phone call
by Mr. Haegele on January 24, 1997 to further discuss this matter.

    No further discussions between the Company and Parent regarding a possible
acquisition occurred until April 19, 1999, Mr. Haegele and Mr. Vardeman met
again in Las Vegas, Nevada to discuss the possible acquisition of the Company by
Parent.

    On August 25, 1999, Mr. Haegele and Gary Kanipe, President of RSI Products
Inc., a subsidiary of Parent, met with Mr. Vardeman in Dallas, Texas to make a
proposal to acquire the Company and to discuss a price range for the
transaction.

    On September 28, 1999, the Company entered into a confidentiality agreement
with Parent. Parent then began its due diligence review of the Company's
business and financial condition. Concurrently with its due diligence review,
Parent engaged in various discussions and meetings with management and employees
of the Company, its counsel and Frost Securities to negotiate the terms of the
Merger Agreement and the Shareholder Agreement. Parent's counsel provided an
initial draft of the proposed merger agreement to the Company's counsel on
October 14, 1999.

    The Supervisory Board of TBG Holdings unanimously approved the proposed
transaction at a meeting on October 8, 1999. The Board of Directors of Parent
approved the proposed transaction by unanimous written consent on the same day.
These approvals were subject to the satisfactory completion of Parent's due
diligence review of the Company and negotiation of definitive agreements.

                                       15
<PAGE>
    On November 4, 1999, the Board met to discuss the proposed Merger. On
November 4, 1999, Frost Securities made a presentation to the Board regarding
the fairness from a financial point of view of the proposed per Share
consideration to be received by holders of Shares in the Offer and the Merger
and counsel to the Company explained in detail the terms of the current draft of
the merger agreement and the shareholder agreement. On November 10, 1999, Parent
completed its due diligence review of the Company and informed representatives
of the Company that Parent was willing to proceed with the transaction at a
price of $22.00 per Share. On November 11, 1999 Frost Securities delivered its
opinion to the Board that, as of such date, and subject to the conditions and
limitations set forth therein, the consideration to be received by holders of
Shares in the Offer and the Merger is fair, from a financial point of view. On
November 11, 1999, the Board of Directors of the Company unanimously approved
the Merger Agreement, the Shareholder Agreement, the Offer and the Merger.

    The parties executed and delivered the Merger Agreement and the Shareholder
Agreement on the evening of November 11, 1999 and publicly announced the
transaction before the NYSE opened for trading on the morning of November 12,
1999.

12. PURPOSE OF THE OFFER; THE MERGER AGREEMENT; THE SHAREHOLDER AGREEMENT; PLANS
  FOR THE COMPANY

    PURPOSE.  The purpose of the Offer is to acquire control of and the entire
equity interest in the Company. Following the Offer, the Purchaser and Parent
intend to acquire any remaining equity interest in the Company not acquired in
the Offer by consummating the Merger.

    THE MERGER AGREEMENT.  The Merger Agreement provides that following the
satisfaction of the conditions described below under "Conditions to the Merger",
the Purchaser will be merged with and into the Company, and each outstanding
Share (other than Shares held by shareholders who perfect their dissent rights
under Texas law, Shares owned by the Company as treasury stock and Shares owned
by Parent or any direct or indirect wholly owned subsidiary of Parent or of the
Company) will be converted into the right to receive the Per Share Merger
Consideration, without interest.

    (1) VOTE REQUIRED TO APPROVE MERGER. The TBCA requires, among other things,
that the adoption of any plan of merger or consolidation of the Company be
approved by the Board and generally by two-thirds of the holders of the
Company's outstanding voting securities. Article 2.28D of the TCBA, however,
provides that a corporation's articles of incorporation may provide that the act
of the shareholders on any matter for which the affirmative vote of the holders
of a specified portion of the shares entitled to vote is required by the TBCA
shall be the affirmative vote of the holders of a specified portion, but not
less than a majority of the shares entitled to vote on the matter, rather than
the affirmative vote otherwise required by the TBCA. Under the Company's
articles of incorporation, however, only a majority vote is required to approve
the Merger. The Board has approved the Offer and the Merger. Consequently, the
only additional action of the Company necessary to effect the Merger is approval
by such shareholders if the "short-form" merger procedure described below is not
available. If the Purchaser acquires, through the Offer or otherwise, voting
power with respect to at least a majority of the outstanding Shares (which would
be the case if the Minimum Tender Condition were satisfied and the Purchaser
were to accept for payment Shares tendered pursuant to the Offer), it would have
sufficient voting power to effect the Merger without the vote of any other
shareholder of the Company. However, Article 5.16 of the TBCA also provides that
if a purchaser owns at least 90% of each class of outstanding shares (pursuant
to the Offer or otherwise), the purchaser, by action of the board of directors
of the purchaser and without the action or vote by the shareholders of either
corporation, can effect a short-form merger with the target company.
Accordingly, if, as a result of the Offer or otherwise, the Purchaser acquires
or controls the voting power of at least 90% of the outstanding Shares, the
Purchaser could, and intends to, effect the Merger without prior notice to, or
any action by, any other shareholder of the Company.

    (2) CONDITIONS TO OBLIGATIONS OF EACH PARTY UNDER THE MERGER AGREEMENT. The
respective obligations of each party to effect the Merger under the Merger
Agreement is subject to the satisfaction at or prior to the

                                       16
<PAGE>
Closing Date of the following conditions, any or all of which may be waived by
Parent and the Purchaser, in whole or in part, to the extent permitted by
applicable law: (a) the Merger Agreement shall have been approved by the
requisite vote of the shareholders of the Company, if required by applicable
law; (b) the waiting period (and any extension thereof) applicable to the Merger
under the HSR Act shall have been terminated or shall have expired, and the
period of time for any applicable review process by CFIUS under the Exon-Florio
Act shall have expired and CFIUS shall not have taken any action or made any
recommendation to the President of the United States to block or prevent the
consummation of the Offer or the Merger; (c) any consents, approvals and filings
under any foreign antitrust Law, the absence of which would prohibit the
consummation of the Merger, shall have been obtained or made; (d) no temporary
restraining order, preliminary or permanent injunction or other order issued by
any court of competent jurisdiction or other legal restraint or prohibition
preventing the consummation of the Merger shall be in effect and any party
asserting this condition shall have used all reasonable efforts to prevent the
entry of any such injunction or other order and to appeal as promptly as
possible any such injunction or other order that may be entered; and (e) the
Purchaser shall have accepted for payment and paid for all Shares validly
tendered and not withdrawn pursuant to the Offer; PROVIDED that this condition
shall be deemed satisfied with respect to the obligation of the Purchaser and
Parent to effect the Merger if the Purchaser fails to accept for payment or pay
for Shares pursuant to the Offer in violation of the Merger Agreement.

    (3) TERMINATION OF THE MERGER AGREEMENT. The Merger Agreement may be
terminated and the Offer and the Merger may be abandoned at any time
(notwithstanding approval of the Merger by the shareholders of the Company)
prior to the Effective Time provided that if the Shares are accepted for payment
pursuant to the Offer, neither Parent nor the Purchaser may terminate this
Agreement or abandon the Merger except pursuant to the following clause (a),
(b)(i) or (b)(iii): (a) by mutual written consent of Parent, the Purchaser and
the Company; (b) by either the Parent or the Company (i) if any court of
competent jurisdiction or other governmental authority issues an order, decree
or ruling or takes any other action permanently enjoining, restraining or
otherwise prohibiting the Merger, and such order, decree or ruling or other
action shall have become nonappealable; (ii) if (A) as a result of the failure
of any of the conditions to the Offer, (1) the Purchaser shall have failed to
commence the Offer within 20 days following the date of the Merger Agreement or
(2) the Offer shall have terminated or expired in accordance with its terms
without the Purchaser having purchased any Shares pursuant to the Offer or
(B) Purchaser shall not have accepted for payment any Shares pursuant to the
Offer prior to March 11, 2000 (the "Termination Date"), PROVIDED that the right
to terminate pursuant to clause (b)(ii) shall not be available (x) to the
Company as a result of the occurrence of any event set forth in paragraph (d)
under Section 14 or (y) to any party whose failure to fulfill any of its
obligations under the Merger Agreement or the Shareholder Agreement (each a
"Transaction Agreement" and together the "Transaction Agreements") results in
the failure of any condition set forth in Section 14 or if the failure of such
condition results from facts or circumstances that constitute a breach of any
representation or warranty of such party contained in any Transaction Agreement;
or (iii) if, upon a vote at a duly held meeting to obtain the Company
Shareholder Approval, such approval is not obtained, PROVIDED, HOWEVER, that the
Merger Agreement may not be terminated by Parent pursuant to this
clause (b)(iii) if Parent does not cause all Company Shares acquired pursuant to
the Offer or otherwise owned by the Purchaser or any other subsidiary of Parent
to be voted in favor of the Merger Agreement; (c) by Parent, if the Company
breaches or fails to perform in any material respect any of its representations,
warranties or covenants contained in any Transaction Agreement, which breach or
failure to perform (i) would give rise to the failure of a condition set forth
in Section 14 and (ii) cannot be or has not been cured within 30 days after
written notice to the Company of such breach; (d) by Parent or the Purchaser if
either Parent or the Purchaser is entitled to terminate the Offer as a result of
the occurrence of any event set forth in paragraph (d) of Section 14; or (e) by
the Company if the Board withdraws or modifies its approval or recommendation of
the Transaction Agreements, the Offer or the Merger in the circumstances
described below under the caption "Company Takeover Proposals"; PROVIDED that,
in order for termination pursuant to this clause (e)

                                       17
<PAGE>
to be deemed effective, the Company shall have complied with all of its
obligations as described below under "Company Takeover Proposals", including the
notice provisions therein, and with all applicable requirements described below
under "Fees and Expenses", including payment of the Termination Fee.

    (4) COMPANY TAKEOVER PROPOSALS. Pursuant to the Merger Agreement, the
Company was required to, and to cause its Representatives (as defined below) to,
cease immediately all current discussions and negotiations regarding any
proposal that constitutes, or may reasonably be expected to lead to, a Company
Takeover Proposal (as defined below). Further, the Company has agreed that it
will not, and will not authorize or permit any of its subsidiaries, or any
officer, director, employee, investment banker, financial advisor, attorney,
accountant or other advisor or representative (collectively, "Representatives")
of the Company or any of its subsidiaries to, (i) directly or indirectly
solicit, initiate or encourage the submission of any Company Takeover Proposal,
(ii) enter into any agreement with respect to any Company Takeover Proposal or
(iii) directly or indirectly participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take any
other action to facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Company Takeover
Proposal; PROVIDED, HOWEVER, that prior to the earlier to occur of acceptance
for payment of Shares pursuant to the Offer and approval of the Merger Agreement
by the Company's shareholders, the Company may, to the extent that a failure to
do so would violate the fiduciary obligations of the Company Board under
applicable law, as determined in good faith by a majority of the Disinterested
Directors (as defined below) based on the advice of outside counsel, in response
to a Superior Company Proposal (as defined below) that was not solicited by the
Company or its Representatives and that did not otherwise result from a breach
or a deemed breach of this provision, and subject to compliance with the notice
requirements described below, (x) furnish information with respect to the
Company to the person making such Superior Company Proposal pursuant to a
confidentiality agreement not less restrictive of the other party than the
confidentiality agreement between the Company and Parent and (y) participate in
discussions or negotiations regarding such Superior Company Proposal.
"Disinterested Director" means, with respect to any Company Takeover Proposal,
any member of the Company Board that is not an affiliate or Representative of
the person making such Company Takeover Proposal. Without limiting the
foregoing, any violation of the restrictions set forth in the preceding sentence
by any Representative or affiliate of the Company or any subsidiary of the
Company, whether or not such person is purporting to act on behalf of the
Company or any subsidiary of the Company or otherwise, would be deemed to be a
breach of the Merger Agreement by the Company.

    The Merger Agreement provides further that, except as described below,
neither the Company, nor the Board nor any committee thereof shall (a) withdraw
or modify, or propose publicly to withdraw or modify, in a manner adverse to
Parent or the Purchaser, the approval or recommendation by the Company Board or
any such committee of the Transaction Agreements, the Offer or the Merger,
(b) approve or cause the Company or any subsidiary of the Company to enter into
any letter of intent, agreement in principle, acquisition agreement or similar
agreement (each, an "Acquisition Agreement") relating to any Company Takeover
Proposal or (c) approve or recommend, or propose publicly to approve or
recommend, any Company Takeover Proposal. Notwithstanding the foregoing, if,
prior to the earlier to occur of acceptance for payment of Shares pursuant to
the Offer and approval of the Merger Agreement by the shareholders of the
Company, the Board receives a Superior Company Proposal which was not solicited
by the Company and which did not otherwise result from a breach of the
non-solicitation provisions of the Merger Agreement, and the Board determines in
good faith, based on the advice of outside counsel, that the failure to do so
would violate its fiduciary obligations under applicable law, the Board may
withdraw or modify its approval or recommendation of the Transaction Agreements,
the Offer or the Merger; PROVIDED that such determination shall be made at a
time that is after the third business day following the receipt by Parent of
written notice advising Parent that the Board is prepared to accept a Superior
Company Proposal, specifying the material terms and conditions of such Superior
Company Proposal and identifying the person making such Superior Company
Proposal.

                                       18
<PAGE>
    In addition, under the Merger Agreement, the Company has agreed to promptly
advise Parent, orally and in writing, of any Company Takeover Proposal or any
inquiry with respect to, or that could reasonably be expected to lead to, any
Company Takeover Proposal (including any change to the terms of any such Company
Takeover Proposal or inquiry) and the identity of the person making any such
Company Takeover Proposal or inquiry. The Company shall (i) keep Parent fully
informed of the status of any such Company Takeover Proposal or inquiry
(including any change to the terms of any such Company Takeover Proposal or
inquiry) and (ii) provide to Parent copies of all correspondence and other
written material sent or provided by any third party to the Company, or by the
Company to any third party, in connection with any Company Takeover Proposal, as
soon as practicable after receipt or delivery thereof.

    The Merger Agreement provides that the provisions described above will not
prohibit the Company from taking and disclosing to its shareholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or making any
disclosure to the Company's shareholders if, in the good faith judgment of the
Company Board, based on the advice of outside counsel, failure so to disclose
would constitute a violation of applicable law; PROVIDED, HOWEVER, that neither
the Company, nor the Board nor any committee thereof shall withdraw or modify,
or propose publicly to withdraw or modify, its position with respect to the
Transaction Agreements, the Offer or the Merger (unless it is permitted to do so
as described above) or approve or recommend, or propose publicly to approve or
recommend, a Company Takeover Proposal.

    "Company Takeover Proposal" means any inquiry, proposal or offer for (a) a
merger, consolidation, dissolution, recapitalization, liquidation or other
business combination involving the Company or any subsidiary of the Company,
(b) the acquisition by any person in any manner, directly or indirectly, of a
number of shares of any class of equity securities of the Company or any
subsidiary of the Company equal to or greater than 20% of the number of such
shares outstanding before such acquisition or (c) the acquisition by any person
in any manner, directly or indirectly, of assets that constitute 20% or more of
the net revenues, net income or assets of the Company or any subsidiary of the
Company, in each case other than the Offer, the Merger and the other
transactions contemplated by the Transaction Agreements (the "Transactions") and
other than the sale of Vertex Satcom Systems, Inc., a subsidiary of the Company,
on terms approved by Parent (the "Satcom Sale") (the transactions referred to in
clauses (a), (b) and (c) being referred to herein as "Company Takeover
Transactions").

    "Superior Company Proposal" means any bona fide proposal made by a third
party to acquire substantially all the equity securities or assets of the
Company, pursuant to a tender or exchange offer, merger, consolidation,
liquidation or dissolution, recapitalization, sale of all or substantially all
its assets or otherwise, (a) on terms which the Board determines in its good
faith judgment to be superior from a financial point of view to the holders of
Shares than the Transactions (based on the written opinion, with only customary
qualifications, of the Company's independent financial advisor, which has been
provided to Parent), taking into account all the terms and conditions of such
proposal, the Transaction Agreements and any proposal by Parent to amend the
terms of the Transactions, (b) for which financing, to the extent required, is
then committed or which, in the good faith judgment of the Board, is reasonably
capable of being obtained by such third party and (c) for which, in the good
faith judgment of the Board, no regulatory approvals are required, including
antitrust approvals, that could not reasonably be expected to be obtained.

    (5) FEES AND EXPENSES. Except with respect to the circumstances described
below, the Merger Agreement provides that each of Parent, the Purchaser and the
Company will bear its own fees and expenses in connection with the Merger
Agreement regardless of whether the Merger is consummated.

    The Merger Agreement provides that in the event that (i) (A) a Company
Takeover Proposal shall have been made known to the Company or shall have been
made directly to its shareholders or any person shall have announced an
intention (whether or not conditional) to make a Company Takeover Proposal,
(B) thereafter the Merger Agreement is terminated as a result of the failure of
the conditions to the Offer, the failure to receive the Company Shareholder
Approval or an uncured material breach by the Company

                                       19
<PAGE>
and (C) within 12 months after such termination a Company Takeover Transaction
is consummated or the Company (or one or more of the Company's subsidiaries
representing in the aggregate 20% or more of the net revenues, net income or the
assets of the Company and the Company's subsidiaries taken as a whole), enters
into an Acquisition Agreement with respect to, approves or recommends a Company
Takeover Transaction or (ii) the Merger Agreement is terminated by the Company
after receiving a Superior Company Proposal as described above or by Parent or
the Purchaser as a result of the failure of the conditions set forth in
paragraph (d) of Section 14, then the Company must promptly, but in no event
later than, in the case of clause (i), the date of the earliest to occur of such
consummation, approval, or recommendation of a Company Takeover Transaction or
the entering into of such Acquisition Agreement, or in the case of clause (ii),
the date of such termination, pay to Parent a fee equal to $3.84 million (the
"Termination Fee"), payable by wire transfer of same day funds. If the Company
is required to pay to Parent a fee pursuant to either of the above clauses, the
Company will also reimburse Parent and the Purchaser for all their out-of-pocket
expenses actually incurred in connection with the Transaction Agreements, the
Offer, the Merger and the other Transactions in an amount not to exceed
$640,000. Such reimbursement shall be paid upon demand following termination of
the Merger Agreement. The payment of any amounts due pursuant to this provision
do not constitute the exclusive remedy of Parent and the Purchaser under the
Transaction Agreements. Without limiting the generality of the foregoing, in the
event of a breach or deemed breach by the Company of the no solicitation
provisions of the Merger Agreement, Parent and the Purchaser will be entitled to
the other remedies contained in the Merger Agreement, including an injunction,
and all other remedies available at law or in equity to which Parent and the
Purchaser are entitled.

    (6) CONDUCT OF BUSINESS OF THE COMPANY. Pursuant to the Merger Agreement,
the Company has agreed that from the date of the Merger Agreement to the
Effective Time, unless otherwise expressly permitted by the Merger Agreement or
agreed to in writing by Parent, it will and will cause each of its subsidiaries
to: (a) conduct its business diligently and in the usual, regular and ordinary
course of business and in substantially the same manner as previously conducted;
(b) use all reasonable efforts to preserve intact its current business
organization, keep available the services of its current officers and employees
and keep its relationships with customers, suppliers and others having business
dealings with it; (c) maintain its assets in as good working order and condition
as at present, ordinary wear and tear excepted, consistent with past practices;
and (d) maintain in full force and effect current insurance policies or other
comparable insurance coverage with respect to the assets and potential

    (7) PROHIBITED ACTIONS BY THE COMPANY. Under the Merger Agreement, the
Company has agreed that, except as expressly permitted by the Merger Agreement
or otherwise agreed to in writing by Parent, from the date of the Merger
Agreement until the Effective Time, it will not, and will not permit any of its
subsidiaries to, make any material change in personnel, operations or finance,
or do any of the following without the prior written consent of Parent: (i) (A)
declare, set aside or pay any dividends on, or make any other distributions in
respect of, any of its capital stock, other than dividends and distributions by

the issuance of any other securities in respect of, in lieu of or in

otherwise encumber or subject to any lien (A) any shares of its capital stock,

their present terms; (iii) amend the Company charter, the Company by-laws or
other comparable charter or organizational

court or other governmental entity; or (xv) authorize, or commit or agree to

    (8) DIRECTORS. The Merger Agreement provides that, promptly upon the
acceptance for payment of, and payment by the Purchaser for, any Shares pursuant
to the Offer, the Purchaser will be entitled to designate such number of
directors on the Board as will give the Purchaser, subject to compliance with
Section 14(f) of the Exchange Act, representation on the Board equal to at least
that number of directors, rounded up to the next whole number, which is the
product of (a) the total number of directors on the Board (giving effect to the
directors elected pursuant to this sentence) multiplied by (b) the percentage
that (i) such number of Shares so accepted for payment and paid for by the
Purchaser plus the number of Shares otherwise owned by the Purchaser or any
other subsidiary of Parent bears to (ii) the number of such Shares outstanding,
and the Company will, at such time, cause the Purchaser's designees to be so
elected; PROVIDED that in the event that the Purchaser's designees are appointed
or elected to the Board, until the Effective Time the Board will have at least
two directors who were directors on the date of the Merger Agreement and who are
not officers of the Company (the "Independent Directors"); and PROVIDED FURTHER
that in such event, if the number of Independent Directors is reduced below two
for any reason whatsoever, the remaining Independent Director will be entitled
to designate a person to fill such vacancy who will be deemed to be an
Independent Director or, if no Independent Directors then remain, the other
directors will designate two persons to fill such vacancies who are not current
or former officers, shareholders or affiliates of the Company, Parent or the
Purchaser, and such persons will be deemed to be Independent Directors. Subject
to applicable law, the Company will take all action requested by Parent
necessary to effect any such election, including mailing to its shareholders the
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company will
make such mailing with the mailing of the Schedule 14D-9 (provided that the
Purchaser shall have provided to the Company on a timely basis all information
required to be included in the Information Statement with respect to the
Purchaser's designees). In connection with the foregoing, the Company will
promptly, at the option of the Purchaser, either increase the size of the Board
or obtain the resignation of such number of its current directors as is
necessary to enable the Purchaser's designees to be elected or appointed to the
Board as provided above.

    (9) STOCK OPTIONS. The Merger Agreement provides that, as soon as
practicable following the date of the Merger Agreement, the Board (or, if
appropriate, any committee administering the Company Stock Plans (as defined
below)) shall adopt such resolutions or take such other actions as are required
to adjust the terms of all outstanding Company Stock Options and all outstanding
Company SARs (as defined below) to provide that (i) each outstanding Company
Stock Option may be exercised, whether or not such Company Stock Option is
vested, immediately prior to the acceptance for payment of Shares pursuant to
the Offer, contingent on and subject to the consummation of the Offer, PROVIDED
that the Shares issued upon such exercise are tendered into the Offer and not
withdrawn and (ii) each Company Stock Option and Company SAR outstanding that is
not exercised prior to the acceptance for payment of Shares pursuant to the
Offer shall be canceled effective immediately prior to the acceptance for
payment of Shares pursuant to the Offer with the holder thereof becoming
entitled to receive an amount of cash equal to the product of (x) the excess, if
any, of (A) the Per Share Merger Consideration over (B) the exercise price per
Share subject to such Company Stock Option or Company SAR, multiplied by
(y) the number of Shares issuable pursuant to the unexercised portion of such
Company Stock Option or Company SAR; PROVIDED, HOWEVER, that no cash payment
will be made with respect to any Company SAR that is related to a Company Stock
Option in respect of which such a cash payment is made. All amounts payable
pursuant to this paragraph will be subject to any required withholding of taxes
or proof of eligibility of exemption therefrom and will be paid at or as soon as
practicable following the Effective Time, but in any event within one business
day following the Effective Time, without interest.

    The Company will use its best efforts to obtain all consents of the holders
of the Company Stock Options if such consents are determined to be necessary to
effectuate the foregoing as mutually agreed by Parent and the Company. The
cancelation of a Company Stock Option in exchange for the cash payment

                                       22
<PAGE>
described in the preceding paragraph will be deemed a release of any and all
rights the holder of such Company Stock Option had or may have had in respect
thereof, and any necessary consents from all such holders shall so provide.
Notwithstanding anything to the contrary contained in the Merger Agreement,
payment shall, at Parent's request, be withheld in respect of any Company Stock
Option until all necessary consents are obtained.

    As soon as practicable following the date of the Merger Agreement, the Board
(or, if appropriate, any committee administering the Company Stock Plans) will
take or cause to be taken such actions as are required to cause (x) the Company
Stock Plans to terminate as of the Effective Time and (y) the provisions in any
other Company benefit plan providing for the issuance, transfer or grant of any
capital stock of the Company or any interest in respect of any capital stock of
the Company to be deleted as of the Effective Time. The Company will ensure that
following the Effective Time no holder of a Company Stock Option or Company SAR
or any participant in any Company Stock Plan or other Company benefit plan will
have any right thereunder to acquire any capital stock of the Company or the
Surviving Corporation.

    The Company will take or cause to be taken all actions required to cause the
TIW Systems, Inc. Stock Bonus Plan to be amended as of immediately prior to the
Effective Time to provide that, in the event the Company Common Stock ceases to
be readily tradable (within the meaning of Q/A-2(d)(1)(iv)(A) of Treas. Reg.
Section 1.411(d)-4), distributions of benefits under such plan will be in the
form of cash; PROVIDED that the foregoing will not apply in the event that prior
to the Effective Time (i) such plan has received a favorable determination
letter from the Internal Revenue Service in respect of the termination of the
plan, (ii) such plan has been terminated and (iii) all benefits payable under
such plan have been paid in full to each plan participant and beneficiary
entitled to receive benefits in respect of the termination of such plan.

    "Company Stock Option" means any option to purchase Common Stock granted
under any Company Stock Plan.

    "Company SAR" means any stock appreciation right linked to the price of
Common Stock and granted under any Company Stock Plan.

    "Company Stock Plans" means the Company's 1995 Stock Compensation Plan, the
Company's Stock Option Plan for Key Employees, the Company's Non-Employee
Directors Stock Option Plan and the Company's Outside Directors Stock Option
Plan, in each case as amended from time to time.

    (10) INDEMNIFICATION OF DIRECTORS AND OFFICERS. (a) For six years after the
Effective Time, the Surviving Corporation (or any successor to the Surviving
Corporation) will honor all the Company's obligations to indemnify, defend and
hold harmless the present and former officers and directors of the Company and
its subsidiaries and certain other individuals (each an "Indemnified Party")
against losses, claims, damages, liabilities, costs, fees and expenses
(including reasonable fees and disbursements of counsel and judgments, fines,
losses, claims, liabilities and amounts paid in settlement provided that any
such settlement is effected with the written consent of Parent or the Surviving
Corporation, which consent shall not unreasonably be withheld) arising out of
actions or omissions occurring at or prior to the Effective Time ("Losses") to
the extent such obligations of the Company exist under the TBCA, the terms of
the Company charter or the Company by-laws, in each case as in effect on the
date of the Merger Agreement, or under any indemnification agreement between the
Company or any subsidiary of the Company, as applicable, and the Indemnified
Party that has been filed as an exhibit to the Filed Company SEC Documents or
that has been previously identified and delivered to Parent; PROVIDED that in
the event any claim or claims are asserted or made within such six-year period,
all rights to indemnification in respect of any such claim or claims shall
continue until disposition of any and all such claims. In the event that the
Surviving Corporation or any of its successors or assigns (i) consolidates with
or merges into any other person and is not the continuing or surviving
corporation or entity of such consolidation or merger or (ii) transfers or
conveys all or substantially all of its properties and assets to any person,
then, and in each such case, proper provision will be made so that the
successors and assigns of the Surviving Corporation shall expressly assume the
obligations set forth in this paragraph. The provisions described in this
paragraph are (i) intended to be for the benefit of, and to be enforceable by,
each Indemnified Party, his or her heirs and his or her representatives and
(ii) in addition to, and not in substitution for, any other rights to
indemnification or contribution that any such person may have by contract or
otherwise.

                                       23
<PAGE>
    (11) REASONABLE EFFORTS. Upon the terms and subject to the conditions set
forth in the Merger Agreement, each of the parties will use all reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, and to assist and cooperate with the other parties in doing, all things
necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the Offer, the Merger and the other
Transactions, including (i) the obtaining of all necessary actions or
nonactions, waivers, consents and approvals from governmental entities and the
making of all necessary registrations and filings (including filings with
governmental entities, if any) and the taking of all reasonable steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any governmental entity, (ii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging the Transaction Agreements or the consummation of the Transactions,
including seeking to have any stay or temporary restraining order entered by any
court or other governmental entity vacated or reversed and (iv) the execution
and delivery of any additional instruments necessary to consummate the
Transactions and to fully carry out the purposes of the Transaction Agreements;
PROVIDED, HOWEVER, that Parent will not be required to consent to any action
described in paragraph (a) of Section 14. In connection with and without
limiting the foregoing, the Company and the Board will (i) take all action
necessary to ensure that no state takeover statute or similar statute or
regulation is or becomes applicable to any Transaction or the Transaction
Agreements, (ii) if any state takeover statute or similar statute or regulation
becomes applicable to the Transaction Agreements, take all action necessary to
ensure that the Offer, the Merger and the other Transactions may be consummated
as promptly as practicable on the terms contemplated by the Transaction
Agreements and otherwise to minimize the effect of such statute or regulation on
the Offer, the Merger and the other Transactions and (iii) cooperate with Parent
and the Purchaser in the arrangements for obtaining the financing required to
consummate the Offer and the Merger, and to pay related fees and expenses.
Nothing in the Merger Agreement will require Parent to waive any substantial
rights or agree to any substantial limitation on its operations or to dispose of
any asset or collection of assets of the Company, Parent or any of their
respective subsidiaries or affiliates. Notwithstanding the foregoing, the
Company is not prohibited from taking any action permitted by the
non-solicitation provisions of the Merger Agreement described under "Company
Takeover Proposals" above.

    (12)  DIRECTORS AND OFFICERS.  The directors of the Purchaser immediately
prior to the Effective Time will be the directors of the Surviving Corporation,
and the officers of the Company immediately prior to the Effective Time shall be
the officers of the Surviving Corporation, in each case until the earlier of
their resignation or removal or until their respective successors are duly
elected or appointed and qualified.

    (13)  REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties.

    (14)  PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR
WAIVER.  Termination or amendment of, or extensions or waivers under, the Merger
Agreement, in order to be effective, require in the case of Parent, the
Purchaser or the Company, action by its Board of Directors or the duly
authorized designee of its Board of Directors. In the event the Purchaser's
designees are elected to the Board as described above, after such election and
prior to the Effective Time, (i) the affirmative vote of a majority of the
Independent Directors will be required in addition to any required approval by
the full Board to (A) amend or terminate the Merger Agreement on behalf of the
Company, (B) waive any of the Company's rights, benefits or remedies under the
Merger Agreement or (C) extend the time for performance of the Purchaser's
obligations under the Merger Agreement and (ii) the Independent Directors will
have the power, acting together, to exercise any right of the Company under the
Merger Agreement that the Company otherwise fails to exercise to the extent that
the failure to exercise such right would materially adversely affect the holders
of Shares other than Parent, the Purchaser and their respective subsidiaries and
affiliates.

                                       24

THE SHAREHOLDER AGREEMENT.

    Pursuant to the Shareholder Agreement, each Principal Shareholder has
agreed, among other things, to tender all the Shares that he owns (or has the
right to acquire upon the exercise of Company Stock Options) pursuant to the
Offer. In addition, each Principal Shareholder has granted the Purchaser an
option to purchase all his Shares at a price per Share equal to the Offer Price
in the event that such Principal Shareholder fails to tender such Shares
pursuant to the Offer, or withdraws such Shares prior to expiration of the
Offer. The Shareholder Agreement and all rights and obligations of the parties
to the Shareholder Agreement will terminate on the earlier to occur of the
Effective Time and the termination of the Merger Agreement in accordance with
its terms.

    Each Principal Shareholder severally has agreed that prior to the
termination of the Shareholder Agreement, except as otherwise provided therein:
(a) such Principal Shareholder will not (i) sell, transfer, pledge, assign or
otherwise dispose of, or enter into any contract, option or other arrangement
(including any profit sharing arrangement) with respect to the sale, transfer,
pledge, assignment or other disposition of such Principal Shareholder's Shares
to any person other than pursuant to the Offer and the Merger, (ii) enter into
any voting arrangement, whether by proxy, voting agreement or otherwise, with
respect to such Principal Shareholder's Shares or (iii) commit or agree to take
any of the foregoing actions, (b) until the Merger is consummated or the Merger
Agreement is terminated, such Principal Shareholder will not, nor will such
Principal Shareholder permit any investment banker, attorney or other advisor or
representative of such Principal Shareholder to (i) directly or indirectly
solicit, initiate or encourage the submission of any Company Takeover Proposal,
(ii) enter into any agreement with respect to any Company Takeover Proposal or
(iii) directly or indirectly participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, any Company
Takeover Proposal; PROVIDED, HOWEVER, that the Principal Shareholder may furnish
information with respect to the Company to a person and participate in
discussions or negotiations with such person regarding a Superior Company
Proposal if at such time the Company is permitted to furnish information and
engage in discussions or negotiations with, and is actually furnishing
information to and engaging in discussions or negotiations with, such person
regarding such Superior Company Proposal pursuant to the nonsolicitation
provisions of the Merger Agreement, (c) at any meeting of shareholders of the
Company called to vote upon the Merger and the Merger Agreement or at any
adjournment thereof or in any other circumstances upon which a vote, consent or
other approval (including by written consent) with respect to the Merger and the
Merger Agreement is sought, such Principal Shareholder will, including by
executing a written consent solicitation if requested by Parent, vote (or cause
to be voted) such Principal Shareholder's Shares in favor of the Merger
Agreement and (d) at any meeting of shareholders of the Company or at any
adjournment thereof or in any other circumstances upon which such Principal
Shareholder's vote, consent or other approval is sought, such Principal
Shareholder will vote (or cause to be voted) such Principal Shareholder's Shares
against (i) any merger agreement or merger (other than the Merger Agreement and
the Merger), consolidation, combination, sale of substantial assets,
reorganization, recapitalization, dissolution, liquidation or winding up of or
by the Company, (ii) any Company Takeover Proposal and (iii) any amendment of
the Company's charter or bylaws or other proposal or transaction involving the
Company or any of its subsidiaries, which amendment or other proposal or
transaction would in any manner impede, frustrate, prevent, delay or nullify the
Offer, the Merger, the Merger Agreement or any of the other Transaction or
change in any manner the voting rights of any class of capital stock of the
Company. The Shareholder Agreement provides that each Principal Shareholder
executed the Shareholder Agreement solely in his or her capacity as the record
holder and beneficial owner of such Principal Shareholder's Shares and nothing
therein shall limit or affect any actions taken by a Principal Shareholder in
his capacity as an officer or director of the Company or any subsidiary of the
Company to the extent specifically permitted by the Merger Agreement.

    Under the Shareholder Agreement each Principal Shareholder has, subject to
termination of the Shareholder Agreement, irrevocably granted to, and appointed,
Parent, Stephen Green and Jack Haegele, or any of them, and any individual
designated by any of them, and each of them, such Principal

                                       25
<PAGE>
Shareholder's proxy and attorney-in-fact (with full power of substitution), for
and in the name, place and stead of such Principal Shareholder, to vote such
Principal Shareholder's Shares, or grant a consent or approval in respect of
such Shares, in the manner specified above.

    THE CONFIDENTIALITY AGREEMENT.  Pursuant to the Confidentiality Agreement
dated September 28, 1999, between the Company and Parent (the "Confidentiality
Agreement"), the Company and Parent agreed to keep confidential certain
information exchanged between such parties. The Confidentiality Agreement also
contains customary standstill provisions. The Merger Agreement provides that
certain information exchanged pursuant to the Merger Agreement will be subject
to the Confidentiality Agreement.

    DISSENT RIGHTS.  Holders of Shares do not have dissenters' rights as a
result of the Offer alone. However, if the Merger is consummated, holders of
Shares will have certain rights pursuant to the provisions of Articles 5.11,
5.12, 5.13 and 5.16 of the TBCA to dissent from the Merger Agreement and to
demand payment in cash of the fair value of their Shares. If the statutory
procedures are complied with, such rights can lead to a judicial determination
of the fair value required to be paid in cash to such dissenting holders for
their shares. Any such judicial determination of the fair value of Shares, in
the case where the proposed corporate action is submitted to a vote of the
shareholders, will be the value of the Shares as of the day immediately
preceding the Shareholder meeting, excluding any appreciation or depreciation in
anticipation of the proposed action. In the case where the proposed corporate
action is approved without a meeting, the fair value of the Shares will be the
value of the Shares as of the date the written consent authorizing the action
was delivered to the Company, excluding any appreciation or depreciation in
anticipation of the action.

    If any holder of Shares who demands appraisal under the TBCA fails to
perfect, or effectively withdraws or loses his right to appraisal, as provided
in the TBCA, the Shares of such holder will be converted into the Per Share
Merger Consideration in accordance with the Merger Agreement.

    The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the TBCA and is qualified in its entirety by the full
text of Articles 5.11, 5.12, 5.13 and 5.16 of the TBCA.

    FAILURE TO FOLLOW THE STEPS REQUIRED BY ARTICLES 5.11, 5.12, 5.13 AND 5.16
OF THE TBCA FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH
RIGHTS.

    GOING PRIVATE TRANSACTIONS.  The Merger would have to comply with any
applicable Federal law operative at the time of its consummation. Rule 13e-3
under the Exchange Act is applicable to certain "going private" transactions.
The Purchaser does not believe that Rule 13e-3 will be applicable to the Merger
unless the Merger is consummated more than one year after the termination of the
Offer. If applicable, Rule 13e-3 would require, among other things, that certain
financial information concerning the Company and certain information relating to
the fairness of the Merger and the consideration offered to minority
shareholders be filed with the SEC and disclosed to minority shareholders prior
to consummation of the Merger.

    PLANS FOR THE COMPANY.  Parent intends to conduct a detailed review of the
Company and its assets, corporate structure, dividend policy, capitalization,
operations, properties, policies, management and personnel and to consider,
subject to the terms of the Merger Agreement, what, if any, changes would be
desirable in light of the circumstances then existing, and reserves the right to
take such actions or effect such changes as it deems desirable. Such changes
could include changes in the Company's business, corporate structure,
capitalization, management or dividend policy.

    Except as otherwise described in this Offer to Purchase, none of the
Purchaser, Parent or TBG Holdings have any current plans or proposals that would
relate to, or result in, any extraordinary corporate transaction involving the
Company or any of its subsidiaries, such as a merger, reorganization or
liquidation involving the Company, a sale or transfer of a material amount of
assets of the Company or any

                                       26
<PAGE>
of its subsidiaries, any change in the Company's capitalization or dividend
policy or any other material change in the Company's business, corporate
structure or personnel.

13. DIVIDENDS AND DISTRIBUTIONS

    Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the following actions without the prior written consent of
Parent: (i) declare, set aside or pay any dividends on, or make any other
distributions in respect of, any of its capital stock other than dividends and
distributions by a direct or indirect wholly owned subsidiary of the Company to
its parent, (ii) split, combine or reclassify any of its capital stock or issue
or authorize the issuance of any other securities in respect of, in lieu of or
in substitution for shares of its capital stock, (iii) purchase, redeem or
otherwise acquire any shares of capital stock of the Company or any subsidiary
of the Company or any other securities or (iv) issue, deliver, sell, grant,
pledge or otherwise encumber or subject to any lien (a) any shares of its
capital stock, (b) other voting securities, (c) any securities convertible into
or exchangeable for, or any options, warrants or rights to acquire, any such
shares, voting securities or convertible or exchangeable securities or (d) any
"phantom" stock, "phantom" stock rights, stock appreciation rights or
stock-based performance units, other than pursuant to the provisions of the
Merger Agreement relating to Company Stock Options and the TIW Systems, Inc.
Stock Bonus Plan. Nothing herein shall constitute a waiver by the Purchaser or
Parent of any of its rights under the Merger Agreement or a limitation of
remedies available to the Purchaser or Parent for any breach of the Merger
Agreement, including termination thereof.

    If, on or after November 11, 1999, the Company should take any of the
actions described in clause (ii), (iii) or (iv) in the above paragraph, then,
subject to the provisions of Section 14, the Purchaser, in its sole discretion,
may make such adjustments as it deems appropriate in the Offer Price and other
terms of the Offer, including, without limitation, the number or type of
securities offered to be purchased.

    If, on or after November 11, 1999, the Company should declare, set aside or
pay any dividends on, or make any other distributions in respect of, any of its
capital stock other than dividends and distributions by a direct or indirect
wholly owned subsidiary of the Company to its parent, then, subject to the
provisions of Section 14, (a) the Offer Price may, in the sole discretion of the
Purchaser, be reduced by the amount of any such cash dividend or cash
distribution and (b) the whole of any such noncash dividend, distribution or
issuance to be received by the tendering shareholders will (i) be received and
held by the tendering shareholders for the account of the Purchaser and will be
required to be promptly remitted and transferred by each tendering shareholder
to the Depositary for the account of the Purchaser, accompanied by appropriate
documentation or transfer, or (ii) at the direction of the Purchaser, be
exercised for the benefit of the Purchaser, in which case the proceeds of such
exercise will promptly be remitted to the Purchaser. Pending such remittance and
subject to applicable law, the Purchaser will be entitled to all rights and
privileges as owner of any such noncash dividend, distribution, issuance or
proceeds and may withhold the entire Offer Price or deduct from the Offer Price
the amount or value thereof, as determined by the Purchaser in its sole
discretion.

14. CERTAIN CONDITIONS OF THE OFFER

    Notwithstanding any other term of the Offer or the Merger Agreement, the
Purchaser shall not be required to accept for payment or, subject to any
applicable rules and regulations of the SEC, including Rule 14e-1(c) under the
Exchange Act (relating to the Purchaser's obligation to pay for or return
tendered Shares promptly after the termination or withdrawal of the Offer), to
pay for any Shares tendered pursuant to the Offer unless (i) there shall have
been validly tendered and not withdrawn prior to the expiration of the Offer
that number of Shares which would represent at least a majority of the
outstanding Shares on a fully diluted basis, (ii) any waiting period under the
HSR Act applicable to the purchase of Shares pursuant to the Offer shall have
expired or been terminated and (iii) the period of time for any applicable
review process by CFIUS under the Exon-Florio Act shall have expired and CFIUS

                                       27
<PAGE>
consummation of the Offer or the Merger. Furthermore, notwithstanding any other
term of the Offer or the Merger Agreement, the Purchaser shall not be required
to commence the Offer, accept for payment or, subject as aforesaid, to pay for
any Shares not theretofore accepted for payment or paid for, and may terminate
or amend the Offer, (x) with the consent of the Company or (y) without the
consent of the Company if, at any time on or after the date of the Merger
Agreement and before the acceptance of such shares for payment or the payment
therefor, any of the following conditions exists:

        (a) there shall be pending or threatened any suit, action or proceeding
    by any Governmental Entity (as defined in the Merger Agreement), or by any

    restrain or prohibit the making or consummation of the Offer or the Merger
    or any other Transaction, or seeking to obtain from the Company, Parent or

    (ii) seeking to prohibit or limit the ownership or operation by the Company,

    respective subsidiaries or affiliates to dispose of or hold separate any
    material portion of the business or assets of the Company, Parent or any of
    their respective subsidiaries or affiliates, as a result of the Offer, the
    Merger or any other Transaction, (iii) seeking to impose limitations on the
    ability of Parent or the Purchaser to acquire or hold, or exercise full
    rights of ownership of, any Shares, including the right to vote the Company
    Common Stock purchased by it on all matters properly presented to the
    shareholders of the Company, or (iv) seeking to prohibit Parent or any of
    its subsidiaries from effectively controlling in any material respect the
    business or operations of the Company and the Company Subsidiaries;

        (b) any statute, rule, regulation, legislation, interpretation,
    judgment, order or injunction shall be enacted, entered, enforced,
    promulgated, amended or issued with respect to, or deemed applicable to, or
    any consent or approval withheld with respect to, (i) Parent, the Company or
    any of their respective subsidiaries or affiliates or (ii) the Offer, the
    Merger or any other Transaction, in either such case by any Governmental
    Entity that is reasonably likely to result, directly or indirectly, in any

        (c) since the date of execution of the Merger Agreement, there shall
    have been any event, change, effect or development that, individually or in
    the aggregate, has had or would reasonably be expected to have a Company
    Material Adverse Effect (as defined in the Merger Agreement), other than any
    event, change, effect or development to the extent attributable to (i) the
    economy or the securities markets in general, (ii) the Merger Agreement or
    the transactions contemplated hereby or the announcement thereof or
    (iii) the Company's industry in general, and not specifically relating to
    the Company or the Company Subsidiaries;

        (d)(i) it shall have been publicly disclosed or Parent shall have
    otherwise learned that beneficial ownership (determined for the purposes of
    this paragraph as set forth in Rule 13d-3 promulgated under the Exchange
    Act) of more than 35% of the outstanding Shares has been acquired by another
    person or (ii)(A) the Company or any of its directors or officers shall have
    breached Section 5.02 of the Merger Agreement (other than an immaterial
    breach), (B) the Board shall have withdrawn or modified its approval or

    (C) the Company or any of its directors or officers shall have made any

    Section 5.02(d) of the Merger Agreement that has the effect of
    (x) withdrawing, modifying or changing the approval or recommendation of the

    Purchaser, (y) approving or recommending to the shareholders of the Company
    a Company Takeover Proposal or (z) approving or recommending that the

<PAGE>
    Takeover Proposal or is related thereto, or (D) the Board shall have failed
    to reaffirm publicly and unconditionally its recommendation to the Company's
    shareholders that they accept the Offer and give the Company Shareholder
    Approval by midnight, New York City time, on the third business day
    following Parent's written request to do so (which request may be made at
    any time that a Company Takeover Proposal is pending), which public
    reaffirmation must also include the unconditional rejection of such Company
    Takeover Proposal;

        (e) any representation or warranty of the Company in any Transaction
    Agreement that is qualified as to materiality shall not be true and correct
    or any such representation or warranty that is not so qualified shall not be
    true and correct in any material respect, as of the date of the Merger

        (f) the Company shall have failed to perform in any material respect any

    The foregoing conditions are for the sole benefit of the Purchaser and
Parent and may be asserted by the Purchaser or Parent regardless of the
circumstances giving rise to such condition or may be waived by the Purchaser
and Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent, the Purchaser or any other affiliate of
Parent at any time to exercise any of the foregoing rights shall not be deemed a
waiver of any such right, the waiver of any such right with respect to
particular facts and circumstances shall not be deemed a waiver with respect to
any other facts and circumstances, and each such right shall be deemed an
ongoing right that may be asserted at any time and from time to time.

15. CERTAIN LEGAL MATTERS

    Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the SEC and other publicly available
information concerning the Company, none of the Purchaser, Parent or TBG
Holdings is aware of any license or regulatory permit that appears to be
material to the business of the Company and its subsidiaries, taken as a whole,
that might be adversely affected by the Purchaser's acquisition of Shares (and
the indirect acquisition of the stock of the Company's subsidiaries), as
contemplated herein or of any approval or other action by any governmental
entity that would be required for the acquisition or ownership of Shares by the
Purchaser as contemplated herein. Should any such approval or other action be
required, the Purchaser, Parent and TBG Holdings currently contemplate that such
approval or action will be sought, except as described below under "State
Takeover Laws". While, except as otherwise expressly described in this
Section 15, the Purchaser does not presently intend to delay the acceptance for
payment of or payment for Shares tendered pursuant to the Offer pending the
outcome of any such matter, there can be no assurance that any such approval or
other action, if needed, would be obtained or would be obtained without
substantial conditions or that failure to obtain any such approval or other
action might not result in consequences adverse to the Company's business or
that certain parts of the Company's business might not have to be disposed of if
such approvals were not obtained or such other actions were not taken or in
order to obtain any such approval or other action. If certain types of adverse
action are taken with respect to the matters discussed below, the Purchaser
could, subject to the terms and conditions of the Merger Agreement, decline to
accept for payment or pay for any Shares tendered. See Section 14 for certain
conditions to the Offer.

    STATE TAKEOVER LAWS. A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable to
attempts to acquire securities of corporations that are incorporated or have
assets, shareholders, executive offices or places of business in such states. In
Edgar v.

                                       29
<PAGE>
MITE Corp., the Supreme Court of the United States held that the Illinois
Business Takeover Act, which involved state securities laws that make the
takeover of certain corporations more difficult, imposed a substantial burden on
interstate commerce and therefore was unconstitutional. In CTS Corp. v. Dynamics
Corp. of America, however, the Supreme Court of the United States held that a
state may, as a matter of corporate law and, in particular, those laws
concerning corporate governance, constitutionally disqualify a potential
acquiror from voting on the affairs of a target corporation without prior
approval of the remaining shareholders, provided that such laws were applicable
only under certain circumstances. Subsequently, a number of Federal courts ruled
that various state takeover statutes were unconstitutional insofar as they apply
to corporations incorporated outside the state of enactment.

    Article 13.03 of the TBCA limits the ability of a Texas corporation to
engage in business combinations with "affiliated shareholders" (defined
generally as any beneficial owner of 20% or more of the outstanding voting stock
of the corporation) for a period of three years from the time such affiliated
shareholders became the holders of 20% or more of such Shares unless, among
other things, the corporation's board of directors had given its prior approval
to either the business combination or the transaction which resulted in the
shareholder becoming an "affiliated shareholder". The Board has approved the
Merger Agreement and the Shareholder Agreement and the Purchaser's acquisition
of Shares pursuant to the Offer and, therefore, Section 13.03 of the TBCA is
inapplicable to the Merger.

    Except as described herein, the Purchaser has not attempted to comply with
any state takeover statutes in connection with the Offer. The Purchaser reserves
the right to challenge the validity or applicability of any state law allegedly
applicable to the Offer and nothing in this Offer to Purchaser nor any action
taken in connection with the Offer or the Merger is intended as a waiver of that
right. In the event that any state takeover statute is found applicable to the
Offer or the Merger, the Purchaser might be unable to accept for payment or pay
for Shares tendered pursuant to the Offer or be delayed in continuing or
consummating the Offer or the Merger. In such case, the Purchaser might not be
obligated to accept for payment or pay for any Shares tendered. See Section 14.

ANTITRUST.

    UNITED STATES ANTITRUST LAW.  Under the provisions of the HSR applicable to
the Offer, the acquisition of Shares under the Offer may be consummated
following the expiration of a 15-calendar day waiting period following the
filing by the Trust of a Notification and Report Form with respect to the Offer,
unless the Trust receives a request for additional information or documentary
material from the Antitrust Division or the FTC or unless early termination of
the waiting period is granted. The Trust has made such filing. If, within the
initial 15-day waiting period, either the Antitrust Division or the FTC requests
additional information or material from the Trust concerning the Offer, the
waiting period will be extended and would expire at 11:59 p.m., New York City
time, on the tenth calendar day after the date of substantial compliance by the
Trust with such request. Only one extension of the waiting period pursuant to a
request for additional information is authorized by the HSR Act. Thereafter,
such waiting period may be extended only by court order or with the consent of
the Trust. In practice, complying with a request for additional information or
material can take a significant amount of time. In addition, if the Antitrust
Division or the FTC raises substantive issues in connection with a proposed
transaction, the parties frequently engage in negotiations with the relevant
governmental agency concerning possible means of addressing those issues and may
agree to delay consummation of the transaction while such negotiations continue.
Expiration or termination of the applicable waiting period under the HSR Act is
a condition to the Purchaser's obligation to accept for payment and pay for
Shares tendered pursuant to the Offer.

    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed acquisition
of the Company. At any time before or after the Purchaser's acquisition of
Shares pursuant to the Offer, the Antitrust Division or the FTC could take such
action under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares pursuant to the
Offer or the consummation of the Merger or seeking the

                                       30
<PAGE>
divestiture of Shares acquired by the Purchaser or the divestiture of
substantial assets of the Company or its subsidiaries or the Trust or its
subsidiaries. Private parties may also bring legal action under the antitrust
laws under certain circumstances. Based upon a preliminary examination of
information provided by the Company relating to the businesses in which the
Trust and the Company are engaged, Parent and the Purchaser believe that the
acquisition of Shares by Purchaser will not violate the antitrust laws.
Nevertheless, there can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, of the
result thereof.

OTHER LAWS.

    EXON-FLORIO ACT.  The Exon-Florio Act applies to all acquisitions proposed
or pending by or with foreign persons which could result in foreign control of
persons engaged in interstate commerce in the United States. The Exon-Florio Act
empowers the President of the United States to prohibit or suspend mergers,
acquisitions or takeovers by or with foreign persons if the President finds,
after investigation, credible evidence that the foreign person might take action
that threatens to impair the national security of the United States and that
other provisions of existing law do not provide adequate and appropriate
authority to protect the national security.

    The President has designated CFIUS as the agency authorized under the
Exon-Florio Act to receive notices and other information and to conduct a review
process, which consists of a determination whether an investigation should be
undertaken and making any such investigation. Any determination by CFIUS that an
investigation is called for must be made within thirty days after its acceptance
of written notification concerning a proposed transaction. In the event that
CFIUS determines to undertake an investigation, such investigation must be
completed within forty-five days after such determination. Upon completion or
termination of any such investigation, CFIUS must report to the President and
present its recommendation. The President then has fifteen days in which to
suspend or prohibit the proposed transaction or to seek other appropriate
relief. In order for the President to exercise his authority to suspend or
prohibit a proposed transaction, the President must make two findings: (i) that
there is credible evidence that leads the President to believe that the foreign
interest exercising control might take action that threatens to impair national
security and (ii) that provisions of law other than the Exon-Florio Act and the
International Emergency Economic Powers Act do not in the President's judgment
provide adequate and appropriate authority for the President to protect the
national security in connection with the acquisition. Such findings are not
subject to judicial review. If the President makes such findings, he may take
action for such time as he considers appropriate to suspend or prohibit the
relevant acquisition. The President may direct the Attorney General to seek
appropriate relief, including divestment relief, in the District Courts of the
United States in order to implement and enforce the Exon-Florio Act. The
Exon-Florio Act does not obligate the parties to a proposed acquisition to
notify CFIUS of a proposed transaction. However, if notice of a proposed
acquisition is not submitted to CFIUS, then the transaction remains indefinitely
subject to review by the President under the Exon-Florio Act, unless it is
determined that CFIUS does not have jurisdiction over the transaction.

    The Purchaser and the Company have made a filing under the Exon-Florio Act.
There can be no assurance that CFIUS will not determine to conduct an
investigation of the proposed acquisition of the Company and, if an
investigation is commenced, there can be no assurance regarding the outcome of
such investigation. If the results of such investigation are adverse to the
Purchaser, the Purchaser will not be obligated to accept for payment or pay for
any Shares tendered pursuant to the Offer.

16. FEES AND EXPENSES

    First Union Securities is acting as Dealer Manager in connection with the
Purchaser's acquisition of the Company. First Union Securities will receive
customary compensation for its services as Dealer Manager in connection with the
Offer. Parent has also agreed to reimburse First Union Securities for its
reasonable out-of-pocket expenses related to such services, including the
reasonable fees and expenses of

                                       31
<PAGE>
its counsel, and to indemnify First Union Securities and certain related persons
against certain liabilities and expenses, including certain liabilities and
expenses under the Federal securities laws.

    The Purchaser has retained D.F. King & Co., Inc., to act as the Information
Agent and First Union National Bank to serve as the Depositary in connection
with the Offer. The Information Agent and the Depositary each will receive
reasonable and customary compensation for their services, be reimbursed for
certain reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection therewith, including certain liabilities
and expenses under the Federal securities laws.

    None of the Purchaser, Parent or TBG Holdings will pay any fees or
commissions to any broker or dealer or other person (other than the Dealer
Manager and the Information Agent) in connection with the solicitation of
tenders of Shares pursuant to the Offer. Brokers, dealers, banks and trust
companies will be reimbursed by the Purchaser upon request for customary mailing
and handling expenses incurred by them in forwarding material to their
customers.

17. MISCELLANEOUS

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. To the extent the Purchaser, Parent or TBG Holdings becomes aware
of any state law that would limit the class of offerees in the Offer, the
Purchaser reserves the right to amend the Offer and, depending on the timing of
such amendment, if any, will extend the Offer to provide adequate dissemination
of such information to holders of Shares prior to the expiration of the Offer.
In any jurisdiction the securities, blue sky or other laws of which require the
Offer to be made by a licensed broker or dealer, the Offer is being made on
behalf of the Purchaser by the Dealer Manager or one or more registered brokers
or dealers licensed under the laws of such jurisdiction.

    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER, PARENT OR TBG HOLDINGS NOT CONTAINED
IN THIS OFFER TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE,
SUCH INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED.

    The Purchaser, Parent and TBG Holdings have filed with the SEC a
Schedule 14D-1 pursuant to Rule 14d-3 under the Exchange Act, together with
exhibits, furnishing certain additional information with respect to the Offer,
and may file amendments thereto. In addition, the Company has filed a
Schedule 14D-9 pursuant to Rule 14d-9 under the Exchange Act, together with
exhibits, setting forth its recommendation with respect to the Offer and the
reasons for such recommendation and furnishing such additional related
information. Such Schedules and any amendments thereto, including exhibits,
should be available for inspection and copies should be obtainable in the manner
set forth in Section 8 (except that such material will not be available at the

                    NOTE: SIGNATURES MUST BE PROVIDED BELOW
              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

    The undersigned hereby tenders to Signal Acquisition Corporation, a Texas
corporation (the "Purchaser") and a wholly owned subsidiary of TriPoint Global
Communications Inc., a Delaware corporation ("Parent"), the above-described
shares of Common Stock, par value $.10 per share (the "Shares"), of Vertex
Communications Corporation, a Texas corporation (the "Company"), upon the terms
and subject to the conditions set forth in the Purchaser's Offer to Purchase
dated November 18, 1999 (the "Offer to Purchase"), and this Letter of
Transmittal (which, together with any amendments or supplements thereto or
hereto, collectively constitute the "Offer"), receipt of which is hereby
acknowledged. If this Letter of Transmittal relates to Shares issuable upon the
exercise of Company Stock Options ("Option Shares") the Company Stock Options
will only be exercised by the Depositary and the Option Shares will only be
tendered by it in the event that the Offer is consummated.

    Upon the terms of the Offer, subject to, and effective upon, acceptance for
payment of, and payment for, the Shares tendered herewith in accordance with the
terms of the Offer, the undersigned hereby sells, assigns and transfers to, or
upon the order of, the Purchaser all right, title and interest in and to all the
Shares that are being tendered hereby (and any and all other Shares or other
securities or rights issued in respect thereof on or after November 11, 1999)
and irrevocably constitutes and appoints First Union National Bank (the
"Depositary"), the true and lawful agent and attorney-in-fact of the
undersigned, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to the full extent
of the undersigned's rights with respect to such Shares (and any such other
Shares or securities or rights) (a) to deliver certificates for such Shares (and
any such other Shares or securities or rights) or transfer ownership of such
Shares (and any such other Shares or securities or rights) on the account books
maintained by a Book-Entry Transfer Facility together, in any such case, with
all accompanying evidences of transfer and authenticity to, or upon the order
of, the Purchaser, (b) to present such Shares (and any such other Shares or
securities or rights) for transfer on the Company's books and (c) to receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any such other Shares or securities or rights), all in accordance
with the terms of the Offer.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the tendered Shares
(and any and all other Shares or other securities or rights issued or issuable
in respect of such Shares on or after November 11, 1999) and, when the same are
accepted for payment by the Purchaser, the Purchaser will acquire good title
thereto, free and clear of all liens, restrictions, claims and encumbrances and
the same will not be subject to any adverse claim. The undersigned will, upon
request, execute any additional documents deemed by the Depositary or the
Purchaser to be necessary or desirable to complete the sale, assignment and
transfer of the tendered Shares (and any such other Shares or other securities
or rights).

    All authority conferred or agreed to be conferred pursuant to this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer of Purchase, this tender is irrevocable.

    The undersigned hereby irrevocably appoints Parent, Stephen Green and Jack
Haegele, and each of them, and any other designees of the Purchaser, the
attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to vote at any annual, special or adjourned meeting of the
Company's shareholders or otherwise in such manner as each such attorney-in-fact
and proxy or his or her substitute shall in his or her sole discretion deem
proper with respect to, to execute any written consent concerning any matter as
each such attorney-in-fact and proxy or his or her substitute shall in his or
her sole discretion deem proper with respect to, and to otherwise act as each
such attorney-in-fact and proxy or his or her substitute shall in his sole
discretion deem proper with respect to, the Shares tendered hereby that have
been accepted for payment by the Purchaser prior to the time any such action is
taken and with respect to which the undersigned is entitled to vote (and any and
all other Shares or other securities or rights issued or issuable in respect of
such Shares on or after November 11, 1999). This appointment is effective when,
and only to the extent that, the Purchaser accepts for payment such Shares as
provided in the Offer to Purchase. This power of attorney and proxy are
irrevocable and are granted in consideration of the acceptance for payment of
such Shares in accordance with the terms of the Offer. Upon such acceptance for
payment, all prior powers of attorney, proxies and consents given by the
undersigned with respect to such Shares (and any such other Shares or securities
or rights) will, without further action, be revoked and no subsequent powers of
attorney, proxies, consents or revocations may be given (and, if given, will not
be deemed effective) by the undersigned.

    If the undersigned is tendering Option Shares, in addition to the matters
described above, the undersigned hereby irrevocably appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned, with full power
of substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), to the full extent of the undersigned's rights with
respect to Company Stock Options held by the undersigned, (a) to exercise
Company Stock Options for the Option Shares to be tendered, and (b) to receive
the Option Shares issuable upon exercise of such Company Stock Options. This
appointment will be effective if, when and only to the extent that, the
Purchaser accepts such Option Shares for payment pursuant to the Offer.

    If the undersigned is tendering Option Shares issuable upon exercise of
Company Stock Options, the undersigned, upon request, shall execute and deliver
all additional documents deemed by the Depositary or the Purchaser to be
necessary or desirable to effectuate the exercise of such Company Stock Options
into the Option Shares tendered hereby.

    The undersigned understands that the valid tender of Shares (including
Option Shares) pursuant to any of the procedures described in Section 2 of the
Offer to Purchase and in the Instructions hereto will constitute a binding
agreement between the undersigned and the Purchaser upon the terms and subject
to the conditions of the Offer.

    Unless otherwise indicated herein under "Special Payment Instructions",
please issue the check for the purchase price and/or return any certificates for
Shares not tendered or accepted for payment in the name(s) of the registered
holder(s) appearing under "Description of Shares Tendered". Similarly, unless
otherwise indicated under "Special Delivery Instructions", please mail the check
for the purchase price and/or return any certificates for Shares not tendered or
accepted for payment (and accompanying documents, as appropriate) to the
address(es) of the registered holder(s) appearing under "Description of Shares
Tendered". In the event that both the "Special Delivery Instructions" and the
"Special Payment Instructions" are completed, please issue the check for the
purchase price and/or return any certificates for Shares not tendered or
accepted for payment (and any accompanying documents, as appropriate) in the
name of, and deliver such check and/or return such certificates (and any
accompanying documents, as appropriate) to, the person or persons so indicated.
Please credit any Shares tendered herewith by book-entry transfer that are not
accepted for payment by crediting the account at the Book-Entry Transfer
Facility designated above. The undersigned recognizes that the Purchaser has no
obligation pursuant to "Special Payment Instructions" to transfer any Shares
from the name of the registered holder thereof if the Purchaser does not accept
for payment any of the Shares so tendered. The payment made to the undersigned
for each Option Share tendered will be an amount equal to the Offer Price minus
the exercise price of the related exercised Company Stock Option. The amount
paid to employees for Option Shares will be reduced by the amount of any wage
and employment withholding taxes required to be deducted and withheld with
respect to the making of such payment under the Internal Revenue Code of 1986,
as amended, or under any provision of state, local, or foreign law. For each
Option Share tendered, an amount equal to the exercise price of the Company
Stock Option exercised for such Option Share shall be paid to the Company.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

    1.  GUARANTEE OF SIGNATURES.  No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this Instruction, includes any
participant in the Book-Entry Transfer Facilities' system whose name appears on
a security position listing as the owner of the Shares) of Shares tendered
herewith, unless such registered holder(s) has completed either the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on this Letter of Transmittal or (b) if such Shares are tendered
for the account of a firm that is a participant in the Security Transfer Agents
Medallion Program or the New York Stock Exchange Guarantee Program or the Stock
Exchange Medallion Program or by any other "eligible guarantor institution", as
such term is defined in Rule 17-Ad-15 under the Securities Exchange Act of 1934,
as amended (each, an "Eligible Institution"). In all other cases, all signatures
on this Letter of Transmittal must be guaranteed by an Eligible Institution. See
Instruction 5.

    2.  REQUIREMENTS OF TENDER.  This Letter of Transmittal is to be completed
by shareholders either if certificates are to be forwarded herewith or, unless
an Agent's Message (as defined below) is utilized, if delivery of Shares is to
be made pursuant to the procedures for book-entry transfer set forth in
Section 2 of the Offer to Purchase. For a shareholder to validly tender Shares
pursuant to the Offer, either (a) a Letter of Transmittal (or a facsimile
thereof), properly completed and duly executed, together with any required
signature guarantees or, in the case of a book-entry transfer, an Agent's
Message, and any other required documents, must be received by the Depositary at
one of its addresses set forth herein prior to the Expiration Date (as defined
in the Offer to Purchase) and either certificates for tendered Shares must be
received by the Depositary at one of such addresses or Shares must be delivered
pursuant to the procedures for book-entry transfer set forth herein (and a
Book-Entry Confirmation (as defined in the Offer to Purchase) must be received
by the Depositary), in each case, prior to the Expiration Date, or (b) the
tendering shareholder must comply with the guaranteed delivery procedures set
forth below and in Section 2 of the Offer to Purchase.

    Shareholders whose certificates for Shares are not immediately available or
who cannot deliver their certificates and all other required documents to the
Depositary or complete the procedures for book-entry transfer prior to the
Expiration Date may tender their Shares by properly completing and duly
executing the Notice of Guaranteed Delivery pursuant to the guaranteed delivery
procedures set forth in Section 2 of the Offer to Purchase. Pursuant to such
procedures, (a) such tender must be made by or through an Eligible Institution,
(b) a properly completed and duly executed Notice of Guaranteed Delivery
substantially in the form provided by the Purchaser must be received by the
Depositary prior to the Expiration Date and (c) the certificates for all
tendered Shares in proper form for transfer (or a Book-Entry Confirmation with
respect to all such Shares), together with a Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, or, in the case of a book-entry transfer, an Agent's Message, and
any other required documents, must be received by the Depositary within three
trading days after the date of execution of such Notice of Guaranteed Delivery
as provided in Section 2 of the Offer to Purchase. A "trading day" is any day on
which the New York Stock Exchange is open for business.

    "Agent's Message" means a message transmitted by the Book-Entry Transfer
Facility to, and received by, the Depositary and forming a part of a Book-Entry
Confirmation, that states that such Book-Entry Transfer Facility has received an
express acknowledgment from the participant in such Book-Entry Transfer Facility
tendering the Shares that such participant has received and agrees to be bound
by the terms of the Letter of Transmittal and that the Purchaser may enforce
such agreement against such participant.

    THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY,
IS AT THE ELECTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE
OF A BOOK- ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL,
REGISTERED MAIL, WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.

                                       7
<PAGE>
    No alternative, conditional (except as provided herein for tendering Option
Shares) or contingent tenders will be accepted and no fractional Shares will be
purchased. All tendering shareholders, by execution of this Letter of
Transmittal (or facsimile thereof), waive any right to receive any notice of the
acceptance of their Shares for payment.

    3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
schedule attached hereto.

    4.  PARTIAL TENDERS (APPLICABLE TO CERTIFICATE SHAREHOLDERS ONLY).  If fewer
than all the Shares evidenced by any certificate submitted are to be tendered,
fill in the number of Shares that are to be tendered in the box entitled "Number
of Shares Tendered". In any such case, new certificate(s) for the remainder of
the Shares that were evidenced by the old certificate(s) will be sent to the
registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the acceptance of payment
of, and payment for, the Shares tendered herewith. All Shares represented by
certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.

    5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder of the Shares
tendered hereby, the signature must correspond with the name as written on the
face of the certificate(s) without any change whatsoever.

    If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

    If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.

    If this Letter of Transmittal or any certificates or stock powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and proper evidence satisfactory to the
Purchaser of their authority so to act must be submitted.

    When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and transmitted hereby, no endorsements of certificates or
separate stock powers are required unless payment is to be made to or
certificates for Shares not tendered or accepted for payment are to be issued to
a person other than the registered owner(s). Signatures on such certificates or
stock powers must be guaranteed by an Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of certificates listed, the certificates must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered owner or owners appear on the certificates.
Signatures on such certificates or stock powers must be guaranteed by an
Eligible Institution.

    6.  STOCK TRANSFER TAXES.  The Purchaser will pay any stock transfer taxes
with respect to the transfer and sale of Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares not tendered or accepted for payment are to be
registered in the name of, any person(s) other than the registered owner(s), or
if tendered certificates are registered in the name of any person(s) other than
the person(s) signing this Letter of Transmittal, the amount of any stock
transfer taxes (whether imposed on the registered owner(s) or such person(s))
payable on account of the transfer to such person(s) will be deducted from the
purchase price unless satisfactory evidence of the payment of such taxes or
exemption therefrom is submitted.

    Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter of
Transmittal.

                                       8
<PAGE>
    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued
in the name of, and/or certificates for Shares not accepted for payment are to
be issued in the name of, a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to a person other than the signer of this Letter of Transmittal or to
an address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed.

    8.  WAIVER OF CONDITIONS.  The Purchaser reserves the absolute right in its
sole discretion to waive any of the specified conditions of the Offer, in whole
or in part, in the case of any Shares tendered.

    9.  31% BACKUP WITHHOLDING.  In order to avoid backup withholding of Federal
income tax on payments of cash pursuant to the Offer, a shareholder surrendering
Shares in the Offer must, unless an exemption applies, provide the Depositary
with such shareholder's correct taxpayer identification number ("TIN") on
Substitute Form W-9 below in this Letter of Transmittal and certify under
penalties of perjury that such TIN is correct and that such shareholder is not
subject to backup withholding. If a shareholder does not provide such
shareholder's correct TIN or fails to provide the certifications described
above, the Internal Revenue Service (the "IRS") may impose a $50 penalty on such
shareholder and payment of cash to such shareholder pursuant to the Offer may be
subject to backup withholding of 31%.

    Backup withholding is not an additional tax. Rather, the amount of the
backup withholding can be credited against the Federal income tax liability of
the person subject to the backup withholding, provided that the required
information is given to the IRS. If backup withholding results in an overpayment
of tax, a refund can be obtained by the shareholder upon filing an income tax
return.

    The shareholder is required to give the Depositary the TIN (I.E., social
security number or employer identification number) of the record owner of the
Shares. If the Shares are held in more than one name or are not in the name of
the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.

    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
shareholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
shareholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN is
provided to the Depositary. However, such amounts will be refunded to such
shareholder if a TIN is provided to the Depositary within 60 days.

    Certain shareholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding.
Noncorporate foreign shareholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, or a Form W-8BEN,
Certificate of Foreign Status of Beneficial Owner for United States Tax
Witholding, copies of which may be obtained from the Depositary, in order to
avoid backup withholding. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.

    10.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance or additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent or the Dealer Manager at their respective
addresses set forth below.

                                       9
<PAGE>
    11.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate
representing Shares has been lost, destroyed or stolen, the shareholder should
promptly notify the Depositary by checking the box immediately preceding the
special payment/special delivery instructions and indicating the number of
Shares so lost, destroyed or stolen, or call the Transfer Agent at
1-800-635-9270. The shareholder will then be instructed by the Depositary or the
Transfer Agent as to the steps that must be taken in order to replace the
certificate. This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE
THEREOF) TOGETHER WITH ANY SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY
TRANSFER, AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED
BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR
TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED
PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE
EXPIRATION DATE, OR THE TENDERING SHAREHOLDER MUST COMPLY WITH THE PROCEDURES
FOR GUARANTEED DELIVERY.

SHARES THAT WOULD CONSTITUTE AT LEAST A MAJORITY OF ALL OUTSTANDING SHARES ON A
FULLY DILUTED BASIS, (B) ANY WAITING PERIOD UNDER THE HART-SCOTT-RODINO
ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED, APPLICABLE TO THE PURCHASE OF
SHARES PURSUANT TO THE OFFER HAVING EXPIRED OR BEEN TERMINATED, (C) THE PERIOD
OF TIME FOR ANY APPLICABLE REVIEW PROCESS BY THE COMMITTEE ON FOREIGN INVESTMENT
IN THE UNITED STATES ("CFIUS") UNDER SECTION 721(A) OF THE DEFENSE PRODUCTION
ACT OF 1950, AS AMENDED, HAVING EXPIRED, AND CFIUS NOT HAVING TAKEN ANY ACTION
OR MADE ANY RECOMMENDATION TO THE PRESIDENT OF THE UNITED STATES TO BLOCK OR TO
PREVENT THE OFFER OR THE MERGER (AS DEFINED BELOW) AND (D) RECEIVING CERTAIN
OTHER REGULATORY AND ANTITRUST CLEARANCES.

    We urge you to contact your clients promptly. Please note that the Offer and
withdrawal rights will expire at 12:00 midnight, New York City time, on
Thursday, December 16, 1999, unless extended.

    The Board of Directors of the Company has unanimously approved the Offer and
the Merger and determined that the terms of the Offer and the Merger are fair
to, and in the best interests of, the Company's shareholders, and recommends
that shareholders of the Company accept the Offer and tender their Shares.

    The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of November 11, 1999 (the "Merger Agreement") among Parent, the Purchaser and
the Company pursuant to which, as soon as practicable following the consummation
of the Offer and the satisfaction or waiver of certain conditions, the Purchaser
will be merged with and into the Company (the "Merger"), with the Company
surviving the Merger as a wholly owned subsidiary of Parent. At the effective
time of the Merger, each outstanding Share (other than Shares held by
shareholders who perfect their dissent rights under Texas law, Shares owned by
the Company as treasury stock and Shares owned by the Parent or any direct or
indirect wholly owned subsidiary of Parent or of the Company) will be converted
into the right to receive $22.00 in cash, without interest thereon, as set forth
in the Merger Agreement and described in the Offer to Purchase. The Merger
Agreement provides that the Purchaser may assign any or all of its rights and
obligations (including the right to purchase Shares in the Offer) to Parent or
any wholly owned subsidiary of Parent, but no such assignment shall relieve the
Purchaser of its obligations under the Merger Agreement.

    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (a) certificates for
(or a timely Book-Entry Confirmation (as defined in the Offer to Purchase) with
respect to) such Shares, (b) a Letter of Transmittal (or a facsimile thereof),
properly completed, and duly executed, with any required signature guarantees,
or, in the case of a book-entry transfer effected pursuant to the procedure set
forth in Section 2 of the Offer to Purchase, an Agent's message (as defined in
the Offer to Purchase), and (c) any other documents required by the Letter of
Transmittal. Accordingly, tendering shareholders may be paid at different times
depending upon when certificates for Shares or Book-Entry Confirmations with
respect to Shares are actually received by the Depositary. Under no
circumstances will interest be paid on the purchase price of the Shares to be
paid by the Purchaser, regardless of any extension of the Offer or any delay in
making such payment.

    None of the Purchaser or Parent will pay any fees or commissions to any
broker or dealer or other person (other than the Dealer Manager, the Depositary
and the Information Agent as described in the Offer to Purchase) in connection
with the solicitation of tenders of Shares pursuant to the Offer. You will be
reimbursed by the Purchaser upon request for customary mailing and handling
expenses incurred by you in forwarding the enclosing Offering materials to your
customers.

Vertex Communications Corporation, a Texas corporation (the "Company"), upon the
terms and subject to the conditions set forth in the Offer. Also enclosed is the
Letter to Shareholders of the Company from the Chairman of the Board of the
Company accompanied by the Company's Solicitation/Recommendation Statement on
Schedule 14D-9.

    We (or our nominees) are the holder of record of shares held by us for your
account. A tender of such shares can be made only by us as the holder of record
and pursuant to your instructions. The Letter of Transmittal is furnished to you
for your information only and cannot be used to tender shares held by us for
your account.

    We request instructions as to whether you wish to tender any of or all the
Shares held by us for your account pursuant to the terms and conditions set
forth in the Offer.

    Your attention is directed to the following:

        1. The offer price is $22.00 per Share net to the seller in cash,
    without interest thereon, upon the term and subject to the conditions of the
    Offer.

        2. The Offer is being made for all outstanding Shares.

        3. The Board of Directors of the Company has unanimously approved the
    Offer and the Merger (as defined below) and determined that the terms of the
    Offer and the Merger are fair to, and in the best interests of, the
    Company's shareholders and unanimously recommends that shareholders of the
    Company accept the Offer and tender their Shares.

        4. The Offer is being made pursuant to the Agreement and Plan of Merger
    dated as of November 11, 1999 (the "Merger Agreement") among Parent, the
    Purchaser and the Company pursuant to which, as soon as practicable
    following the consummation of the Offer and the satisfaction or waiver of
    certain conditions, the Purchaser will be merged with and into the Company
    with the Company surviving the merger as a wholly owned subsidiary of Parent
    (the "Merger"). At the effective time of the Merger, each outstanding Share
    (other than Shares held by shareholders who perfect their dissent rights
    under Texas law, Shares owned by the Company as treasury stock and Shares
    owned by Parent or any direct or indirect wholly owned subsidiary of Parent)
    will be converted into the right to receive $22.00 in cash, without
    interest, as set forth in the Merger Agreement and described in the Offer to
    Purchase. The Merger Agreement provides that the Purchaser may assign any or
    all of its rights and obligations (including the right to purchase Shares in
    the Offer) to Parent or
<PAGE>
    any wholly owned subsidiary of Parent, but no such assignment shall relieve
    the Purchaser of its obligations under the Merger Agreement.

        5. THE OFFER AND WITHDRAWAL RIGHT EXPIRE AT 12:00 MIDNIGHT, NEW YORK
    CITY TIME, ON THURSDAY, DECEMBER 16, 1999 (THE "EXPIRATION DATE"), UNLESS
    THE OFFER IS EXTENDED BY THE PURCHASER, IN WHICH EVENT THE TERM "EXPIRATION
    DATE" SHALL MEAN THE LATEST TIME AT WHICH THE OFFER, AS SO EXTENDED BY THE
    PURCHASER, WILL EXPIRE.

        6. The Offer is conditioned upon, among other things, (1) there being
    validly tendered and not withdrawn prior to the Expiration Date such number
    of Shares that would constitute at least a majority of all outstanding
    Shares on a fully diluted basis, (2) any waiting period under the
    Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, applicable
    to the purchase of Shares pursuant to the Offer having expired or been
    terminated, (3) the period of time for any applicable review process by the
    Committee on Foreign Investment in the United States ("CFIUS") under
    Section 721(a) of the Defense Production Act of 1950, as amended, having
    expired and CFIUS not having taken any action or made any recommendation to
    the President of the United States to block or prevent the Offer or the
    Merger and (4) receiving certain other regulatory and antitrust clearances.

        7. Any stock transfer taxes applicable to a sale of Shares to the
    Purchaser will be borne by the Purchaser, except as otherwise provided in
    Instruction 6 of the Letter of Transmittal.

        8. Tendering Shareholders will not be obligated to pay brokerage fees or
    commissions to the Dealer Manager, the Depositary or the Information Agent
    or, except as set forth in Instruction 6 of the Letter of Transmittal,
    transfer taxes on the purchase of Shares by Purchaser pursuant to the Offer.
    However, federal income tax backup withholding at a rate of 31% may be
    required, unless an exemption is provided or unless the required taxpayer
    identification information is provided. See Instruction 9 of the Letter of
    Transmittal.

    Your instructions to us should be forwarded promptly to permit us to submit
a tender on your behalf prior to the Expiration Date.

    If you wish to have us tender any of or all the Shares held by us for your
account, please so instruct us by completing, executing, detaching and returning
to us the instruction form on the detachable part hereof. An envelope to return
your instructions to us is enclosed. If you authorize the tender of your Shares,
all such Shares will be tendered unless otherwise specified on the detachable
part hereof. YOUR INSTRUCTIONS SHOULD BE FORWARDED TO US IN AMPLE TIME TO PERMIT
US TO SUBMIT A TENDER ON YOUR BEHALF PRIOR TO THE EXPIRATION DATE.

    Payment for Shares accepted for payment pursuant to the Offer will in all
cases be made only after timely receipt by First Union National Bank (the
"Depositary") of (a) certificates for (or a timely Book-Entry Confirmation (as
defined in the Offer to Purchase) with respect to) such Shares, (b) a Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed, with
any required signature guarantees, or, in the case of a book-entry transfer
effected pursuant to the procedure set forth in Section 2 of the Offer to
Purchase, an Agent's Message, and (c) any other documents required by the Letter
of Transmittal. Accordingly, tendering shareholders may be paid at different
times depending upon when certificates for Shares or Book-Entry Confirmations
with respect to Shares are actually received by the Depositary. UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE
PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN
MAKING SUCH PAYMENT.

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. To the extent the Purchaser or Parent becomes aware of any state
law that would limit the class of Offerees in the Offer, the Purchaser reserves
the right to amend the Offer and, depending on the timing of such amendment, if
any, will extend the Offer to provide adequate dissemination of such information
to holders of Shares prior to the expiration of the Offer. In any jurisdiction
where the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer is being made on behalf of the Purchaser by
First Union Securities, Inc., the Dealer Manager for the Offer, or one or more
registered brokers or dealers that are licensed under the laws of such
jurisdiction.

  States and which have at least one nonresident partner.

- - Payments made to a nominee.

    Payments of interest not generally subject to backup withholding include the
following:

    Exempt payees described above should file Form W-9 to avoid possible
erroneous backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR
TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND
RETURN IT TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE
DIVIDENDS, ALSO SIGN AND DATE THE FORM.

    Privacy Act Notice.--Section 6109 requires most recipients of dividend,

who must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Beginning January 1, 1984, payers must generally
withhold 31% of taxable interest, dividend, and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
    to furnish your taxpayer identification number to a payer, you are subject
    to a penalty of $50 for each such failure unless your failure is due to
    reasonable cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
    include any portion of an includible payment for interest, dividends, or
    patronage dividends in gross income, such failure will be treated as being
    due to negligence and will be subject to a penalty of 5% on any portion of
    an underpayment attributable to that failure unless there is clear and
    convincing evidence to the contrary.

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
    make a false statement with no reasonable basis which results in no
    imposition of backup withholding, you are subject to a penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
    affirmations may subject you to criminal penalties including fines and/or
    imprisonment.

    FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.

TERMINATED, (3) THE PERIOD OF TIME FOR ANY APPLICABLE REVIEW PROCESS BY THE
COMMITTEE ON FOREIGN INVESTMENT IN THE UNITED STATES ("CFIUS") UNDER SECTION
721(a) OF THE DEFENSE PRODUCTION ACT OF 1950, AS AMENDED, HAVING EXPIRED AND
CFIUS NOT HAVING TAKEN ANY ACTION OR MADE ANY RECOMMENDATION TO THE PRESIDENT
OF THE UNITED STATES TO BLOCK OR PREVENT THE OFFER OR THE MERGER (AS DEFINED
BELOW) AND (4) RECEIVING CERTAIN OTHER REGULATORY AND ANTITRUST CLEARANCES.

     The Offer is being made pursuant to the Agreement and Plan of Merger
dated as of November 11, 1999 (the "Merger Agreement") among Parent, the
Purchaser and the Company pursuant to which, as soon as practicable following
the consummation of the Offer and the satisfaction or waiver of certain
conditions, the Purchaser will be merged with and into the Company, with the
Company surviving the merger as a wholly owned subsidiary of Parent (the
"Merger"). At the effective time of the Merger, each outstanding Share (other
than Shares held by shareholders who perfect their dissent rights under Texas
law, Shares owned by the Company as treasury stock and Shares owned by Parent
or any direct or any indirect wholly owned subsidiary of Parent or of the
Company) will be converted into the right to receive $22.00 in cash, without
interest, as set forth in the Merger Agreement and described in the Offer to
Purchase. The Merger Agreement provides that the Purchaser may assign any or
all of its rights and obligations (including the right to purchase Shares in
the Offer) to Parent or any wholly-owned subsidiary of Parent, but no such
assignment shall relieve the Purchaser of its obligations under the Merger
Agreement.

     Simultaneously with entering into the Merger Agreement, Parent, the
Purchaser and certain shareholders of the Company (collectively, the "Principal
Shareholders") entered into the Company Shareholder Agreement dated as of
November 11, 1999 (the "Shareholder Agreement"), whereby each Principal
Shareholder has agreed, among other things, to tender his Shares pursuant to the
Offer. If the Principal Shareholders fail to tender their Shares, or withdraw
their Shares prior to expiration of the Offer, Parent will have the option to
purchase such Shares at the Offer Price following consummation of the Offer. The
Principal Shareholders collectively own approximately 13.1% of all outstanding
Shares (assuming the exercise of all Company stock options held by the Principal
Shareholders).

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER
AND THE MERGER AND DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE
FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS SHAREHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS OF THE COMPANY ACCEPT THE OFFER AND
TENDER THEIR SHARES.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not withdrawn as, if and when the Purchaser gives oral or written notice
to the Depositary (as defined in the Offer to Purchase) of the Purchaser's
acceptance for payment of such Shares. Upon the terms and subject to the
conditions of the Offer, payment for Shares accepted for payment pursuant to
the Offer will be made by deposit of the purchase price therefor with the
Depositary, which will act as agent for tendering shareholders for the
purpose of receiving payment from the Purchaser and transmitting payment to
tendering shareholders. In all cases, payment for Shares accepted for payment
pursuant to the Offer will be made only after timely receipt by the
Depositary of (a) certificates for such Shares or timely confirmation of
book-entry transfer of such Shares into the Depositary's account at the
Book-Entry Transfer Facility (as defined in the Offer to Purchase) pursuant
to the procedures set forth in Section 2 of the Offer to Purchase, (b) a
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, with any required signature guarantees or, in the case of a
book-entry transfer, an Agent's Message (as defined in the Offer to Purchase)
and (c) any other documents required by the Letter of Transmittal. Under no
circumstances will interest be paid on the purchase price of the Shares to be
paid by the Purchaser, regardless of any extension of the Offer or any delay
in making such payment.

     The term "Expiration Date" means 12:00 Midnight, New York City time, on
Thursday, December 16, 1999, unless and until the Purchaser, in its sole
discretion (but subject to the terms of the Merger Agreement), shall have
extended the period of time during which the Offer is open, in which event
the term "Expiration Date" shall mean the latest time and date at which the
Offer, as so extended by the Purchaser, will expire. Subject to the terms of
the Merger Agreement and applicable rules and regulations of the Securities
and Exchange Commission, the Purchaser reserves the right, in its sole
discretion, at any time and from time to time and regardless of whether or
not any of the events or facts set forth in Section 14 of the Offer to
Purchase shall have occurred, to extend the period of time during which the
Offer is open and thereby delay acceptance for payment of, and the payment
for, any Shares, by giving oral or written notice of such extension to the
Depositary and (b) except as set forth above, amend the Offer in any other
respect by giving oral or written notice of such amendment to the Depositary.
Under no circumstances will interest be paid on the purchase price for
tendered Shares, whether or not the Purchaser exercises its right to extend
the Offer. There can be no assurance that the Purchaser will exercise its
right to extend the Offer. Any such extension will be followed by a public
announcement thereof no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. During any such
extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the right of a tendering shareholder to
withdraw such shareholder's Shares.

<PAGE>

     Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
the Expiration Date and, unless theretofore accepted for payment and paid for
by the Purchaser pursuant to the Offer, may also be withdrawn at any time
after Sunday, January 16, 2000. For a withdrawal to be effective, a written,
telegraphic or facsimile transmission notice of withdrawal must be timely
received by the Depositary at one of its addressees set forth on the back
cover of the Offer to Purchase and must specify the name of the person having
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name of the registered holder of the Shares to be withdrawn, if different
from the name of the person who tendered the Shares. If certificates for
Shares have been delivered or otherwise identified to the Depositary, then
prior to the physical release of such certificates, the serial numbers shown
on such certificates must be submitted to the Depositary and, unless such
Shares have been tendered by an Eligible Institution (as defined in the Offer
to Purchase), the signatures on the notice of withdrawal must be guaranteed
by an Eligible Institution. If Shares have been delivered pursuant to the
procedure for book-entry transfer as set forth in Section 2 of the Offer to
Purchase, any notice of withdrawal must also specify the name and number of
the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Shares and otherwise comply with the Book-Entry Transfer Facility's
procedures. Withdrawals of tenders of shares may not be rescinded, and any
Shares properly withdrawn will thereafter be deemed not validly tendered for
purposes of the Offer. However, withdrawn shares may be retendered by again
following one of the procedures described in Section 2 of the Offer to
Purchase at any time prior to the Expiration Date. All questions as to the
form and validity (including time of receipt) of notices of withdrawal will
be determined by the Purchaser, in its sole discretion, which determination
will be final and binding.

     The Company has provided the Purchaser with the Company's shareholder
list and security position listings for the purpose of disseminating the
Offer to holders of Shares. The Offer to Purchase and the related Letter of
Transmittal and other relevant materials will be mailed to record holders of
Shares and furnished to brokers, dealers, banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the Company's
shareholder lists, or, if applicable, who are listed as participants in a
clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares.

     The information required to be disclosed by Rule 14d-6(e)(1)(vii) under
the Securities Exchange Act of 1934, as amended, is contained in the Offer to
Purchase and is incorporated herein by reference.

annual or quarterly financial statements delivered pursuant to Section 7.1 (or,
prior to the delivery of the first financial statements pursuant to Section 7.1,
consistent with the financial statements as at November 29, 1997; PROVIDED,
HOWEVER, if (a) the Borrower shall object to determining such compliance on such
basis at the time of delivery of such financial statements due to any change in
GAAP or the rules promulgated with respect thereto or (b) the Agent or the
Required Lenders shall so object in writing within 60 days after delivery of
such financial statements, then such calculations shall be made on a basis
consistent with the most recent financial statements delivered by the Borrower

                                CREDIT FACILITIES

         2.1      REVOLVING LOANS.

                  (a) REVOLVING COMMITMENT. Subject to the terms and conditions
         hereof and in reliance upon the representations and warranties set
         forth herein, each Lender severally



                                       26
<PAGE>

         agrees to make available to the Borrower such Lender's Revolving
         Commitment Percentage of revolving credit loans requested by the
         Borrower in Dollars ("REVOLVING LOANS") from time to time from the
         Closing Date until the Maturity Date, or such earlier date as the
         Revolving Commitments shall have been terminated as provided herein for
         the purposes hereinafter set forth; PROVIDED, HOWEVER, that the sum of
         the aggregate principal amount of outstanding Revolving Loans shall not
         exceed FORTY MILLION DOLLARS ($40,000,000) (provided, that until the
         time that amounts outstanding under the loan agreement in connection
         with the Illinois IRB shall have been paid in full as set forth in
         Section 7.17, the aggregate principal amount of outstanding Revolving
         Loans shall not exceed $37,500,000), (as such aggregate maximum amount
         may be reduced from time to time as provided in Section 3.4, the
         "REVOLVING COMMITTED AMOUNT"); PROVIDED, FURTHER, (A) with regard to
         each Lender individually, such Lender's outstanding Revolving Loans
         shall not exceed such Lender's Revolving Commitment Percentage of the
         Revolving Committed Amount, and (B) the aggregate principal amount of
         outstanding Revolving Loans PLUS LOC Obligations PLUS outstanding
         Swingline Loans outstanding shall not exceed the Revolving Committed
         Amount. Revolving Loans may consist of Base Rate Loans or Eurodollar
         Loans, or a combination thereof, as the Borrower may request, and may
         be repaid and reborrowed in accordance with the provisions hereof;
         PROVIDED, HOWEVER, that no more than 10 Eurodollar Loans shall be
         outstanding in the aggregate under this Credit Agreement at any time.
         For purposes hereof, Eurodollar Loans with different Interest Periods
         shall be considered as separate Eurodollar Loans, even if they begin on
         the same date, although borrowings, extensions and conversions may, in
         accordance with the provisions hereof, be combined at the end of
         existing Interest Periods to constitute a new Eurodollar Loan with a
         single Interest Period. Revolving Loans hereunder may be repaid and
         reborrowed in accordance with the provisions hereof.

                  (b) REVOLVING LOAN BORROWINGS. The Borrower shall request
         Revolving Loans as set forth in Section 3.2(a).

                  (c) REPAYMENT. The principal amount of all Revolving Loans
         shall be due and payable in full on the Maturity Date, unless
         accelerated sooner pursuant to Section 9.2.

                  (d) INTEREST. Subject to the provisions of Section 3.1,

                           (i) BASE RATE LOANS. During such periods as Revolving
                  Loans shall be comprised in whole or in part of Base Rate
                  Loans, such Base Rate Loans shall bear interest at a per annum
                  rate equal to the applicable Adjusted Base Rate.

                           (ii) EURODOLLAR LOANS. During such periods as
                  Revolving Loans shall be comprised in whole or in part of
                  Eurodollar Loans, such Eurodollar Loans shall bear interest at
                  a per annum rate equal to the applicable Adjusted Eurodollar
                  Rate.

                  Interest on Revolving Loans shall be payable in arrears on
         each applicable Interest Payment Date (or at such other times as may be
         specified herein).



                                       27
<PAGE>

                  (e) REVOLVING NOTES. The Revolving Loans made by each Lender
         shall be evidenced by a duly executed promissory note of the Borrower
         payable to such Lender in an original principal amount equal to such
         Lender's Revolving Commitment Percentage of the Revolving Committed
         Amount and in substantially the form of EXHIBIT 2.1(E).

         2.2      LETTER OF CREDIT SUBFACILITY.

                  (a) ISSUANCE. Subject to the terms and conditions hereof and
         of the LOC Documents, if any, and any other terms and conditions which
         the Issuing Lender may reasonably require and in reliance upon the
         representations and warranties set forth herein, the Issuing Lender
         agrees to issue, and each Lender severally agrees to participate in the
         issuance by the Issuing Lender of Letters of Credit in Dollars from
         time to time from the Closing Date until the Maturity Date as the
         Borrower may request, in a form acceptable to the Issuing Lender;
         PROVIDED, HOWEVER, that (i) the LOC Obligations outstanding shall not
         at any time exceed FIFTEEN MILLION DOLLARS ($15,000,000) (the "LOC
         COMMITTED AMOUNT") and (ii) the sum of the aggregate principal amount
         of outstanding Revolving Loans PLUS LOC Obligations outstanding PLUS
         outstanding Swingline Loans shall not at any time exceed the Revolving
         Committed Amount. No Letter of Credit shall (x) except as otherwise
         agreed by the Agent, have an original expiry date more than one year
         from the date of issuance or (y) as originally issued or as extended,
         have an expiry date extending beyond the Maturity Date. Each Letter of
         Credit shall comply with the related LOC Documents. The issuance and
         expiry dates of each Letter of Credit shall be a Business Day.

                  (b) NOTICE AND REPORTS. The request for the issuance of a
         Letter of Credit shall be submitted by the Borrower to the Issuing
         Lender at least three (3) Business Days prior to the requested date of
         issuance. The Issuing Lender will, at least quarterly, disseminate to
         each of the Lenders a detailed report specifying the Letters of Credit
         which are then issued and outstanding and any activity with respect
         thereto which may have occurred since the date of the prior report, and
         including therein, among other things, the beneficiary, the face amount
         and the expiry date, as well as any payment or expirations which may
         have occurred.

                  (c) PARTICIPATION. Each Lender, upon issuance of a Letter of
         Credit, shall be deemed to have purchased without recourse a
         Participation Interest from the applicable Issuing Lender in such
         Letter of Credit and the obligations arising thereunder and any
         collateral relating thereto, in each case in an amount equal to its pro
         rata share of the obligations under such Letter of Credit (based on the
         respective Revolving Commitment Percentages of the Lenders) and shall
         absolutely, unconditionally and irrevocably assume and be obligated to
         pay to the Issuing Lender and discharge when due, its pro rata share of
         the obligations arising under such Letter of Credit. Without limiting
         the scope and nature of each Lender's Participation Interest in any
         Letter of Credit, to the extent that the Issuing Lender has not been
         reimbursed as required hereunder or under any such Letter of Credit,
         each such Lender shall pay to the Issuing Lender its pro rata share of
         such unreimbursed drawing in same day funds on the day of notification
         by the Issuing Lender of an unreimbursed drawing pursuant to the
         provisions of subsection (d) below. The obligation of each Lender to so
         reimburse the Issuing Lender shall be absolute and unconditional and




                                       28
<PAGE>

         shall not be affected by the occurrence of a Default, an Event of
         Default or any other occurrence or event. Any such reimbursement shall
         not relieve or otherwise impair the obligation of the Borrower to
         reimburse the Issuing Lender under any Letter of Credit, together with
         interest as hereinafter provided.

                  (d) REIMBURSEMENT. In the event of any drawing under any
         Letter of Credit, the Issuing Lender will promptly notify the Borrower.
         Unless the Borrower shall immediately notify the Issuing Lender that
         the Borrower intends to otherwise reimburse the Issuing Lender for such
         drawing, the Borrower shall be deemed to have requested that the
         Lenders make a Revolving Loan in the amount of the drawing as provided
         in subsection (e) below on the related Letter of Credit, the proceeds
         of which will be used to satisfy the related reimbursement obligations.
         The Borrower promises to reimburse the Issuing Lender on the day of
         drawing under any Letter of Credit (either with the proceeds of a
         Revolving Loan obtained hereunder or otherwise) in same day funds. If
         the Borrower shall fail to reimburse the Issuing Lender as provided
         hereinabove, the unreimbursed amount of such drawing shall bear
         interest at a per annum rate equal to the Adjusted Base Rate PLUS 2%.
         The Borrower's reimbursement obligations hereunder shall be absolute
         and unconditional under all circumstances irrespective of any rights of
         setoff, counterclaim or defense to payment the Borrower may claim or
         have against the Issuing Lender, the Agent, the Lenders, the
         beneficiary of the Letter of Credit drawn upon or any other Person,
         including without limitation any defense based on any failure of the
         Borrower or any other Credit Party to receive consideration or the
         legality, validity, regularity or unenforceability of the Letter of
         Credit. The Issuing Lender will promptly notify the other Lenders of
         the amount of any unreimbursed drawing and each Lender shall promptly
         pay to the Agent for the account of the Issuing Lender in Dollars and
         in immediately available funds, the amount of such Lender's pro rata
         share of such unreimbursed drawing. Such payment shall be made on the
         day such notice is received by such Lender from the Issuing Lender if
         such notice is received at or before 2:00 P.M. (Charlotte, North
         Carolina time) otherwise such payment shall be made at or before 12:00
         Noon (Charlotte, North Carolina time) on the Business Day next
         succeeding the day such notice is received. If such Lender does not pay
         such amount to the Issuing Lender in full upon such request, such
         Lender shall, on demand, pay to the Agent for the account of the
         Issuing Lender interest on the unpaid amount during the period from the
         date of such drawing until such Lender pays such amount to the Issuing
         Lender in full at a rate per annum equal to, if paid within two (2)
         Business Days of the date that such Lender is required to make payments
         of such amount pursuant to the preceding sentence, the Federal Funds
         Rate and thereafter at a rate equal to the Base Rate. Each Lender's
         obligation to make such payment to the Issuing Lender, and the right of
         the Issuing Lender to receive the same, shall be absolute and
         unconditional, shall not be affected by any circumstance whatsoever and
         without regard to the termination of this Credit Agreement or the
         Commitments hereunder, the existence of a Default or Event of Default
         or the acceleration of the obligations of the Borrower hereunder and
         shall be made without any offset, abatement, withholding or reduction
         whatsoever. Simultaneously with the making of each such payment by a
         Lender to the Issuing Lender, such Lender shall, automatically and
         without any further action on the part of the Issuing Lender or such
         Lender, acquire a Participation Interest in an amount equal to such
         payment (excluding the portion of such payment constituting interest
         owing to the Issuing Lender) in the related unreimbursed drawing




                                       29
<PAGE>

         portion of the LOC Obligation and in the interest thereon and in the
         related LOC Documents, and shall have a claim against the Borrower with
         respect thereto.

                  (e) REPAYMENT WITH REVOLVING LOANS. On any day on which the
         Borrower shall have requested, or been deemed to have requested, a
         Revolving Loan advance to reimburse a drawing under a Letter of Credit,
         the Agent shall give notice to the Lenders that a Revolving Loan has
         been requested or deemed requested by the Borrower to be made in
         connection with a drawing under a Letter of Credit, in which case a
         Revolving Loan advance comprised of Base Rate Loans (or Eurodollar
         Loans to the extent the Borrower has complied with the procedures of
         Section 3.2(a)(i) with respect thereto) shall be immediately made to
         the Borrower by all Lenders (notwithstanding any termination of the
         Commitments pursuant to Section 9.2) PRO RATA based on the respective
         Revolving Commitment Percentages of the Lenders (determined before
         giving effect to any termination of the Commitments pursuant to Section
         9.2) and the proceeds thereof shall be paid directly to the Issuing
         Lender for application to the respective LOC Obligations. Each such
         Lender hereby irrevocably agrees to make its pro rata share of each
         such Revolving Loan immediately upon any such request or deemed request
         in the amount, in the manner and on the date specified in the preceding
         sentence NOTWITHSTANDING (i) the amount of such borrowing may not
         comply with the minimum amount for advances of Revolving Loans
         otherwise required hereunder, (ii) whether any conditions specified in
         Section 5.2 are then satisfied, (iii) whether a Default or an Event of
         Default then exists, (iv) failure for any such request or deemed
         request for Revolving Loan to be made by the time otherwise required
         hereunder, (v) whether the date of such borrowing is a date on which
         Revolving Loans are otherwise permitted to be made hereunder or (vi)
         any termination of the Commitments relating thereto immediately prior
         to or contemporaneously with such borrowing. In the event that any
         Revolving Loan cannot for any reason be made on the date otherwise
         required above (including, without limitation, as a result of the
         commencement of a proceeding under the Bankruptcy Code with respect to
         the Borrower or any Credit Party), then each such Lender hereby agrees
         that it shall forthwith purchase (as of the date such borrowing would
         otherwise have occurred, but adjusted for any payments received from
         the Borrower on or after such date and prior to such purchase) from the
         Issuing Lender such Participation Interests in the outstanding LOC
         Obligations as shall be necessary to cause each such Lender to share in
         such LOC Obligations ratably (based upon the respective Revolving
         Commitment Percentages of the Lenders (determined before giving effect
         to any termination of the Commitments pursuant to Section 9.2)),
         PROVIDED that at the time any purchase of Participation Interests
         pursuant to this sentence is actually made, the purchasing Lender shall
         be required to pay to the Issuing Lender, to the extent not paid to the
         Issuing Lender by the Borrower in accordance with the terms of
         subsection (d) above, interest on the principal amount of Participation
         Interests purchased for each day from and including the day upon which
         such borrowing would otherwise have occurred to but excluding the date
         of payment for such Participation Interests, at the rate equal to, if
         paid within two (2) Business Days of the date of the Revolving Loan
         advance, the Federal Funds Rate, and thereafter at a rate equal to the
         Base Rate.

                  (f) DESIGNATION OF CONSOLIDATED PARTIES AS ACCOUNT PARTIES.
         Notwithstanding anything to the contrary set forth in this Credit
         Agreement, including without limitation



                                       30
<PAGE>

         Section 2.2(a), a Letter of Credit issued hereunder may contain a
         statement to the effect that such Letter of Credit is issued for the
         account of a Consolidated Party other than the Borrower, provided that
         notwithstanding such statement, the Borrower shall be the actual
         account party for all purposes of this Credit Agreement for such Letter
         of Credit and such statement shall not affect the Borrower's
         reimbursement obligations hereunder with respect to such Letter of
         Credit.

                  (g) RENEWAL, EXTENSION. The renewal or extension of any Letter
         of Credit shall, for purposes hereof, be treated in all respects the
         same as the issuance of a new Letter of Credit hereunder.

                  (h) UNIFORM CUSTOMS AND PRACTICES. The Issuing Lender may have
         the Letters of Credit be subject to The Uniform Customs and Practice
         for Documentary Credits, as published as of the date of issue by the
         International Chamber of Commerce (the "UCP"), in which case the UCP
         may be incorporated therein and deemed in all respects to be a part
         thereof.

                  (i)      INDEMNIFICATION; NATURE OF ISSUING LENDER'S DUTIES.

                           (i) In addition to its other obligations under this
                  Section 2.2, the Borrower hereby agrees to pay, and protect,
                  indemnify and save each Lender harmless from and against, any
                  and all claims, demands, liabilities, damages, losses, costs,
                  charges and expenses (including reasonable attorneys' fees)
                  that such Lender may incur or be subject to as a consequence,
                  direct or indirect, of (A) the issuance of any Letter of
                  Credit or (B) the failure of such Lender to honor a drawing
                  under a Letter of Credit as a result of any act or omission,
                  whether rightful or wrongful, of any present or future de jure
                  or de facto government or Governmental Authority (all such
                  acts or omissions, herein called "Government Acts").

                           (ii) As between the Borrower and the Lenders
                  (including the Issuing Lender), the Borrower shall assume all
                  risks of the acts, omissions or misuse of any Letter of Credit
                  by the beneficiary thereof. No Lender (including the Issuing
                  Lender) shall be responsible: (A) for the form, validity,
                  sufficiency, accuracy, genuineness or legal effect of any
                  document submitted by any party in connection with the
                  application for and issuance of any Letter of Credit, even if
                  it should in fact prove to be in any or all respects invalid,
                  insufficient, inaccurate, fraudulent or forged; (B) for the
                  validity or sufficiency of any instrument transferring or
                  assigning or purporting to transfer or assign any Letter of
                  Credit or the rights or benefits thereunder or proceeds
                  thereof, in whole or in part, that may prove to be invalid or
                  ineffective for any reason; (C) for errors, omissions,
                  interruptions or delays in transmission or delivery of any
                  messages, by mail, cable, telegraph, telex or otherwise,
                  whether or not they be in cipher; (D) for any loss or delay in
                  the transmission or otherwise of any document required in
                  order to make a drawing under a Letter of Credit or of the
                  proceeds thereof; and (E) for any consequences arising from
                  causes beyond the control of such Lender, including, without
                  limitation,



                                       31
<PAGE>

                  any Government Acts. None of the above shall affect, impair,
                  or prevent the vesting of the Issuing Lender's rights or
                  powers hereunder.

                           (iii) In furtherance and extension and not in
                  limitation of the specific provisions hereinabove set forth,
                  any action taken or omitted by any Lender (including the
                  Issuing Lender), under or in connection with any Letter of
                  Credit or the related certificates, if taken or omitted in
                  good faith, shall not put such Lender under any resulting
                  liability to the Borrower or any other Credit Party. It is the
                  intention of the parties that this Credit Agreement shall be
                  construed and applied to protect and indemnify each Lender
                  (including the Issuing Lender) against any and all risks
                  involved in the issuance of the Letters of Credit, all of
                  which risks are hereby assumed by the Borrower (on behalf of
                  itself and each of the other Credit Parties), including,
                  without limitation, any and all Government Acts. No Lender
                  (including the Issuing Lender) shall, in any way, be liable
                  for any failure by such Lender or anyone else to pay any
                  drawing under any Letter of Credit as a result of any
                  Government Acts or any other cause beyond the control of such
                  Lender.

                           (iv) Nothing in this subsection (i) is intended to
                  limit the reimbursement obligations of the Borrower contained
                  in subsection (d) above. The obligations of the Borrower under
                  this subsection (i) shall survive the termination of this
                  Credit Agreement. No act or omissions of any current or prior
                  beneficiary of a Letter of Credit shall in any way affect or
                  impair the rights of the Lenders (including the Issuing
                  Lender) to enforce any right, power or benefit under this
                  Credit Agreement.

                           (v) Notwithstanding anything to the contrary
                  contained in this subsection (i), the Borrower shall have no
                  obligation to indemnify any Lender (including the Issuing
                  Lender) in respect of any liability incurred by such Lender
                  (A) arising solely out of the gross negligence or willful
                  misconduct of such Lender, as determined by a court of
                  competent jurisdiction, or (B) caused by such Lender's failure
                  to pay under any Letter of Credit after presentation to it of
                  a request strictly complying with the terms and conditions of
                  such Letter of Credit, as determined by a court of competent
                  jurisdiction, unless such payment is prohibited by any law,
                  regulation, court order or decree.

                  (j) RESPONSIBILITY OF ISSUING LENDER. It is expressly
         understood and agreed that the obligations of the Issuing Lender
         hereunder to the Lenders are only those expressly set forth in this
         Credit Agreement and that the Issuing Lender shall be entitled to
         assume that the conditions precedent set forth in Section 5.2 have been
         satisfied unless it shall have acquired actual knowledge that any such
         condition precedent has not been satisfied; PROVIDED, HOWEVER, that
         nothing set forth in this Section 2.2 shall be deemed to prejudice the
         right of any Lender to recover from the Issuing Lender any amounts made
         available by such Lender to the Issuing Lender pursuant to this Section
         2.2 in the event that it is determined by a court of competent
         jurisdiction that the payment with respect to a Letter of Credit
         constituted gross negligence or willful misconduct on the part of the
         Issuing Lender.

                  (k) CONFLICT WITH LOC DOCUMENTS. In the event of any conflict
         between this Credit Agreement and any LOC Document (including any
         letter of credit application), this Credit Agreement shall control.

                  2.3      SWINGLINE LOANS.

         (a) SWINGLINE COMMITMENT. Subject to the terms and conditions hereof
and in reliance upon the representations and warranties herein set forth, the
Swingline Lender, in its individual capacity, agrees to make certain revolving
credit loans to the Borrower (each a "SWINGLINE LOAN" and, collectively, the
"SWINGLINE LOANS") from time to time from the Closing Date until the Maturity
Date for the purposes hereinafter set forth; PROVIDED, HOWEVER, (i) the
aggregate principal amount of Swingline Loans outstanding at any time shall not
exceed FOUR MILLION DOLLARS ($4,000,000) (the "SWINGLINE COMMITTED AMOUNT"), and
(ii) the sum of the aggregate principal amount of outstanding Revolving Loans
plus LOC Obligations PLUS outstanding Swingline Loans at any time shall not
exceed the Revolving Committed Amount. Swingline Loans hereunder shall be made
as Base Rate Loans in accordance with the provisions of this Section 2.3, and
may be repaid and reborrowed in accordance with the provisions hereof.

         (b) SWINGLINE LOAN ADVANCES.

                  (i) NOTICES; DISBURSEMENT. Whenever the Borrower desires a
         Swingline Loan advance hereunder it shall give written notice (or
         telephone notice promptly confirmed in writing) to the Swingline Lender
         not later than 12:00 Noon (Charlotte, North Carolina time) on the
         Business Day of the requested Swingline Loan advance. Each such notice
         shall be irrevocable and shall specify (A) that a Swingline Loan
         advance is requested, (B) the date of the requested Swingline Loan
         advance (which shall be a Business Day) and (C) the principal amount of
         the Swingline Loan advance requested. Each Swingline Loan shall be made
         as a Base Rate Loan and shall have such maturity date as the Swingline
         Lender and the Borrower shall agree upon receipt by the Swingline
         Lender of any such notice from the Borrower. The Swingline Lender shall
         initiate the transfer of funds representing the Swingline Loan advance
         to the Borrower by 3:00 P.M. (Charlotte, North Carolina time) on the
         Business Day of the requested borrowing.

                  (ii) MINIMUM AMOUNT. Each Swingline Loan shall be in a minimum
         principal amount of $300,000 and in integral multiples of $100,000 in
         excess thereof (or the remaining amount of the Swingline Committed
         Amount, if less).

                  (iii) REPAYMENT OF SWINGLINE LOANS. The principal amount of
         all Swingline Loans shall be due and payable on the earlier of (A) the
         maturity date agreed to by the Swingline Lender and the Borrower with
         respect to such Loan (which maturity date shall be upon demand by the
         Agent) or (B) the Maturity Date. The Swingline Lender may, at any time,
         in its sole discretion, by written notice to the Borrower and the
         Lenders, demand repayment of its Swingline Loans by way of a Revolving
         Loan advance, in which case the Borrower shall be deemed to have
         requested a Revolving Loan advance comprised solely of Base Rate Loans
         in the amount of such Swingline Loans; PROVIDED, HOWEVER, that any such
         demand shall be deemed to have been given one Business Day prior to the
         Maturity Date



                                       33

         and on the date of the occurrence of any Event of Default described in
         Section 9.1 and upon acceleration of the indebtedness hereunder and the
         exercise of remedies in accordance with the provisions of Section 9.2.
         Each Lender hereby irrevocably agrees to make its pro rata share of
         each such Revolving Loan in the amount, in the manner and on the date
         specified in the preceding sentence NOTWITHSTANDING (I) the amount of
         such borrowing may not comply with the minimum amount for advances of
         Revolving Loans otherwise required hereunder, (II) whether any
         conditions specified in Section 5.2 are then satisfied, (III) whether a
         Default or Event of Default then exists, (IV) failure of any such
         request or deemed request for Revolving Loan to be made by the time
         otherwise required hereunder, (V) whether the date of such borrowing is
         a date on which Revolving Loans are otherwise permitted to be made
         hereunder or (VI) any termination of the Commitments relating thereto
         immediately prior to or contemporaneously with such borrowing. In the
         event that any Revolving Loan cannot for any reason be made on the date
         otherwise required above (including, without limitation, as a result of
         the commencement of a proceeding under the Bankruptcy Code with respect
         to the Borrower or any other Credit Party), then each Lender hereby
         agrees that it shall forthwith purchase (as of the date such borrowing
         would otherwise have occurred, but adjusted for any payments received
         from the Borrower on or after such date and prior to such purchase)
         from the Swingline Lender such participations in the outstanding
         Swingline Loans as shall be necessary to cause each such Lender to
         share in such Swingline Loans ratably based upon its Commitment
         Percentage of the Revolving Committed Amount (determined before giving
         effect to any termination of the Commitments pursuant to Section 3.4),
         PROVIDED that (A) all interest payable on the Swingline Loans shall be
         for the account of the Swingline Lender until the date as of which the
         respective participation is purchased and (B) at the time any purchase
         of participations pursuant to this sentence is actually made, the
         purchasing Lender shall be required to pay to the Swingline Lender in
         accordance with the terms of subsection (c)(ii) hereof, interest on the
         principal amount of participation purchased for each day from and
         including the day upon which such borrowing would otherwise have
         occurred to but excluding the date of payment for such participation,
         at the rate equal to the Federal Funds Rate.

         (c)      INTEREST ON SWINGLINE LOANS.

                  (i) Subject to the provisions of Section 3.1, each Swingline
         Loan shall bear interest at a per annum rate (computed on the basis of
         the actual number of days elapsed over a year of 360 days) equal to the
         Base Rate PLUS the Applicable Percentage for Base Rate Loans.

                  (ii) Interest on Swingline Loans shall be payable in arrears
         on each applicable Interest Payment Date (or at such other times as may
         be specified herein).

         (d) SWINGLINE NOTE. The Swingline Loans shall be evidenced by a duly
executed promissory note of the Borrower payable to the Swingline Lender in
substantially the form of EXHIBIT 2.3(D).

                  2.4      TRANCHE A TERM LOAN.

         hereof and in reliance upon the representations and warranties set
         forth herein each Lender severally agrees to make available to the
         Borrower on the Closing Date such Lender's Tranche A Term Loan
         Commitment Percentage of a term loan in Dollars (the "TRANCHE A TERM
         LOAN") in the aggregate principal amount of TWENTY MILLION DOLLARS

         Base Rate Loans or Eurodollar Loans, or a combination thereof, as the
         Borrower may request; PROVIDED, HOWEVER, that no more than 10
         Eurodollar Loans shall be outstanding in the aggregate under this
         Credit Agreement at any time. For purposes hereof, Eurodollar Loans
         with different Interest Periods shall be considered as separate
         Eurodollar Loans, even if they begin on the same date, although
         borrowings, extensions and conversions may, in accordance with the
         provisions hereof, be combined at the end of existing Interest Periods
         to constitute a new Eurodollar Loan with a single Interest Period.
         Amounts repaid on the Tranche A Term Loan may not be reborrowed.

                  (b) BORROWING PROCEDURE. The Borrower shall request Tranche A
         Term Loan borrowings as set forth in Section 3.2(a).

         quarterly installments as follows, unless accelerated sooner pursuant
         to Section 9.2:

         Tranche A Term Loan shall bear interest at a per annum rate equal to:

                           (i) BASE RATE LOANS. During such periods as the

                  Rate.

         Interest on the Tranche A Term Loan shall be payable in arrears on each
         applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (e) TERM NOTES. The portion of the Tranche A Term Loan made by

         considered as separate Eurodollar Loans, even if they begin on the same

         existing Interest Periods to constitute a new Eurodollar Loan with a

                  (d) INTEREST. Subject to the provisions of Section 3.1, the
         Tranche B Term Loan shall bear interest at a per annum rate equal to:

                           (i) BASE RATE LOANS. During such periods as the
                  Tranche B Term Loan shall be comprised in whole or in part of
                  Base Rate Loans, such Base Rate Loans shall bear interest at a
                  per annum rate equal to the applicable Adjusted Base Rate.

                           (ii) EURODOLLAR LOANS. During such periods as the
                  Tranche B Term Loan shall be comprised in whole or in part of
                  Eurodollar Loans, such Eurodollar Loans shall bear interest at
                  a per annum rate equal to the applicable Adjusted Eurodollar
                  Rate.

         Interest on the Tranche B Term Loan shall be payable in arrears on each
         applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (e) TRANCHE B TERM NOTES. The portion of the Tranche B Term
         Loan made by each Lender shall be evidenced by a duly executed
         promissory note of the Borrower payable to such Lender in an original
         principal amount equal to such Lender's Tranche B Term Loan Commitment
         Percentage of the Tranche B Term Loan and substantially in the form of
         EXHIBIT 2.5(E).

                                    SECTION 3

                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         3.1      DEFAULT RATE.

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate 2% greater than the
rate which would otherwise be applicable (or if no rate is applicable, whether
in respect of interest, fees or other amounts, then the Adjusted Base Rate plus
2%).

         3.2      BORROWINGS; EXTENSION AND CONVERSION.

                  (a) (i) NOTICE OF BORROWING. The Borrower shall request a
         Revolving Loan borrowing, Tranche A Term Loan borrowing or a Tranche B
         Term Loan borrowing by written notice (or telephonic notice promptly
         confirmed in writing) to the Agent not later than 11:00 A.M.
         (Charlotte, North Carolina time) on the Business Day prior to the date
         of the requested borrowing in the case of Base Rate Loans, and on the
         third Business Day prior to the date of the requested borrowing in the
         case of Eurodollar Loans; PROVIDED, HOWEVER that only Eurodollar Loans
         with Interest Periods of one month shall be available hereunder until
         the Borrower shall have received notification (which notification in
         any event shall be provided within 90 days after the Closing Date) from
         the Agent that it has completed the syndication process. Each such
         request for borrowing shall be irrevocable and shall specify (A) the
         type of Loan requested, (B) the date of the requested borrowing (which
         shall be a Business Day), (C) the aggregate principal amount to be
         borrowed, and (D) whether the borrowing shall be comprised of Base Rate
         Loans, Eurodollar Loans or a combination thereof, and if Eurodollar
         Loans are requested, the Interest Period(s) therefor. If the Borrower
         shall fail to specify in any such Notice of Borrowing (I) an applicable
         Interest Period in the case of a Eurodollar Loan, then such notice
         shall be deemed to be a request for an Interest Period of one month, or
         (II) the type of Loan requested, then such notice shall be deemed to be
         a request for a Revolving Loan which is a Base Rate Loan hereunder. The
         Agent shall give notice to each affected Lender promptly upon receipt
         of each Notice of Borrowing pursuant to this Section 3.2(a)(i), the
         contents thereof and each such Lender's share of any borrowing to be
         made pursuant thereto.

                           (ii) MINIMUM AMOUNTS. Each Eurodollar Loan shall be
         in a minimum aggregate principal amount of $3,000,000 and integral
         multiples of $1,000,000 in excess thereof. Each Base Rate shall be in a
         minimum aggregate principal amount of $1,000,000 and integral multiples
         of $500,000 in excess thereof (or, as applicable, the remaining amount




                                       39
<PAGE>

         of the Revolving Committed Amount, if less, the remaining principal
         balance of the Tranche A Term Loan, if less, or the remaining principal
         balance of the Tranche B Term Loan, if less).

                           (iii) ADVANCES. Each Lender will make its Revolving
         Commitment Percentage of each Revolving Loan borrowing available to the
         Agent for the account of the Borrower as specified in SECTION 3.15(A),
         or in such other manner as the Agent may specify in writing, by 1:00
         P.M. (Charlotte, North Carolina time) on the date specified in the
         applicable Notice of Borrowing in Dollars and in funds immediately
         available to the Agent. Such borrowing will then be made available to
         the Borrower by the Agent by crediting the account of the Borrower on
         the books of such office with the aggregate of the amounts made
         available to the Agent by the Lenders and in like funds as received by
         the Agent. Each Lender shall make its Tranche A Term Loan Commitment
         Percentage of the Tranche A Term Loan and its Tranche B Term Loan
         Percentage of the Tranche B Term Loan available to the Agent for the
         account of the Borrower at the office of the Agent specified in
         SCHEDULE 2.1(A), or at such other office as the Agent may designate in
         writing, by 1:00 P.M. (Charlotte, North Carolina time) on the Closing
         Date in Dollars and in funds immediately available to the Agent. The
         Borrower hereby irrevocably authorizes the Agent to, and the Agent
         shall, on such date disburse the proceeds of each Revolving Loan
         requested by the Borrower pursuant to this subsection 3.2(a)(iii) in
         immediately available funds by crediting or wiring such proceeds to the
         deposit account of the Borrower identified in the most recent Notice of
         Account Designation substantially in the form of Exhibit 3.2(a)(iii)
         hereto (a "NOTICE OF ACCOUNT DESIGNATION") delivered by the Borrower to
         the Agent or as may be otherwise agreed upon by the Borrower and the
         Agent from time to time.

                  (b) Subject to the terms of Section 5.2, the Borrower shall
         have the option, on any Business Day, to extend existing Loans into a
         subsequent permissible Interest Period or to convert Loans into Loans
         of another interest rate type; PROVIDED, HOWEVER, that (i) except as
         provided in Section 3.8, Eurodollar Loans may be converted into Base
         Rate Loans only on the last day of the Interest Period applicable
         thereto, (ii) Eurodollar Loans may be extended, and Base Rate Loans may
         be converted into Eurodollar Loans, only if no Default or Event of
         Default is in existence on the date of extension or conversion, (iii)
         Loans extended as, or converted into, Eurodollar Loans shall be subject
         to the terms of the definition of "INTEREST PERIOD" set forth in
         Section 1.1 and shall be in such minimum amounts as provided in Section
         3.2(a), (iv) no more than 10 Eurodollar Loans shall be outstanding in
         the aggregate under this Credit Agreement at any time (it being
         understood that, for purposes hereof, Eurodollar Loans with different
         Interest Periods shall be considered as separate Eurodollar Loans, even
         if they begin on the same date, although borrowings, extensions and
         conversions may, in accordance with the provisions hereof, be combined
         at the end of existing Interest Periods to constitute a new Eurodollar
         Loan with a single Interest Period) and (v) any request for extension
         or conversion of a Eurodollar Loan which shall fail to specify an
         Interest Period shall be deemed to be a request for an Interest Period
         of one month. Each such extension or conversion shall be effected by
         the Borrower by giving a Notice of Extension/Conversion (or telephonic
         notice promptly confirmed in writing) to the office of the Agent
         specified in specified in SCHEDULE 2.1(A), or at such other office as
         the Agent may designate in writing, prior to 11:00 A.M. (Charlotte,
         North Carolina time) on the Business Day of, in the case of the
         conversion of a Eurodollar Loan into a Base Rate Loan, and on the third
         Business Day prior to, in the case of the extension of a Eurodollar
         Loan as, or conversion of a Base Rate Loan into, a Eurodollar Loan, the
         date of the proposed extension or conversion, specifying the date of
         the proposed extension or conversion, the Loans to be so extended or
         converted, the types of Loans into which such Loans are to be converted
         and, if appropriate, the applicable Interest Periods with respect
         thereto. Each request for extension or conversion shall be irrevocable
         and shall constitute a representation and warranty by the Borrower of
         the matters specified in subsections (b), (c), (d), (e) and (f) of
         Section 5.2. In the event the Borrower fails to request extension or
         conversion of any Eurodollar Loan in accordance with this Section, or
         any such conversion or extension is not permitted or required by this
         Section, then such Eurodollar Loan shall be automatically converted
         into a Base Rate Loan at the end of the Interest Period applicable
         thereto. The Agent shall give each Lender notice as promptly as
         practicable of any such proposed extension or conversion affecting any
         Loan.

         3.3      PREPAYMENTS.

                  (a) VOLUNTARY PREPAYMENTS. The Borrower shall have the right
         to prepay Loans in whole or in part from time to time, without premium
         or penalty; PROVIDED, HOWEVER, that each partial prepayment of Loans
         shall be in a minimum principal amount of $1,000,000 and integral
         multiples of $100,000. Subject to the foregoing terms, amounts prepaid
         under this Section 3.3(a) shall be applied as the Borrower may elect;
         PROVIDED that if the Borrower fails to specify a voluntary prepayment
         then such prepayment shall be applied first ratably to the Tranche A
         Term Loan and the Tranche B Term Loan (in each case ratably to the
         remaining Principal Amortization Payments thereof), in each case first
         to Base Rate Loans and then to Eurodollar Loans in direct order of
         Interest Period maturities. All prepayments under this Section 3.3(a)
         shall be subject to Section 3.12 but shall be otherwise without premium
         or penalty.

                  (b)      MANDATORY PREPAYMENTS.

                           (i) REVOLVING COMMITTED AMOUNT. If at any time, the
                  sum of the aggregate principal amount of outstanding Revolving
                  Loans plus LOC Obligations outstanding PLUS outstanding
                  Swingline Loans shall exceed the Revolving Committed Amount,
                  the Borrower immediately shall prepay the Revolving Loans and
                  Swingline Loans and (after all Revolving Loans and Swingline
                  Loans have been repaid) cash collateralize the LOC
                  Obligations, in an amount sufficient to eliminate such excess.

                           (ii) EXCESS CASH FLOW. Within 120 days after the end
                  of each fiscal year (commencing with the fiscal year ending
                  November 30, 1999), the Borrower shall prepay the Loans in an
                  amount equal to (x) 50% of the Excess Cash Flow earned during
                  such prior fiscal year less (y) the amount of any voluntary
                  prepayments of the Tranche A Term Loan, the Tranche B Term
                  Loan and (to the extent accompanied by a reduction in the
                  Revolving Committed Amount) the Revolving Loans during such
                  prior fiscal year; PROVIDED, HOWEVER, that the Borrower shall
                  not be required to make



                                       41
<PAGE>

                  prepayments hereunder if, as of the most recently ended fiscal
                  year of the Borrower, the Leverage Ratio was less than 3.0 to
                  1.0. Any payments of Excess Cash Flow shall be applied as set
                  forth in clause (vi) below.

                           (iii) ASSET DISPOSITIONS. Immediately upon the
                  occurrence of any Asset Disposition Prepayment Event with Net
                  Cash Proceeds in excess of $1,000,000, the Borrower shall
                  prepay the Loans in an aggregate amount equal to the Net Cash
                  Proceeds of the related Asset Disposition not applied (or
                  caused to be applied) by the Consolidated Parties during the
                  related Application Period to the purchase, acquisition or
                  construction of Eligible Assets as contemplated by the terms
                  of Section 8.5(f) (such prepayment to be applied as set forth
                  in clause (vi) below); PROVIDED, HOWEVER, that if the Asset
                  Disposition occurs with respect to assets of the Divested
                  Businesses and the Leverage Ratio as of the end of the most
                  recent fiscal quarter of the Borrower was less than 3.75 to
                  1.0 at the time such Asset Disposition occurs, the Borrower
                  may apply Net Cash Proceeds from such Asset Disposition to
                  prepay the Senior Subordinated Notes or, after such time as
                  the pending litigation with respect to Anghel Laboratories,
                  Inc. shall have been settled or otherwise concluded to the
                  satisfaction of the Required Lenders, to redeem or repurchase
                  preferred stock.

                           (iv) DEBT ISSUANCES. Immediately upon receipt by any
                  Consolidated Party of proceeds from any Debt Issuance (other
                  than an Excluded Issuance), the Borrower shall prepay the
                  Loans in an aggregate amount equal to the Net Cash Proceeds of
                  such Debt Issuance to the Lenders (such prepayment to be
                  applied as set forth in clause (vi) below); PROVIDED, HOWEVER,
                  that if the Borrower shall have received in excess of
                  $75,000,000 in Net Cash Proceeds from the issuance of
                  additional subordinated debt on terms and conditions
                  satisfactory to the Required Lenders and as otherwise
                  permitted by Section 8.1(f), the Borrower may apply up to
                  $20,000,000 of such Net Cash Proceeds to prepay the Senior
                  Subordinated Notes or, after such time as the pending
                  litigation with respect to Anghel Laboratories, Inc. shall
                  have been settled or otherwise concluded to the satisfaction
                  of the Required Lenders, to redeem or repurchase preferred
                  stock.

                           (v) ISSUANCES OF EQUITY. Immediately upon receipt by
                  the Borrower of proceeds from any Equity Issuance (other than
                  an Excluded Issuance), the Borrower shall prepay the Loans in
                  an aggregate amount equal to 100% of the Net Cash Proceeds of
                  such Equity Issuance to the Lenders (such prepayment to be
                  applied as set forth in clause (vi) below).

                           (vi) APPLICATION OF MANDATORY PREPAYMENTS. All
                  amounts required to be paid pursuant to this Section 3.3(b)
                  shall be applied as follows: (A) with respect to all amounts
                  prepaid pursuant to Section 3.3(b)(i), to Revolving Loans and
                  Swingline Loans and (after all Revolving Loans and Swingline
                  Loans have been repaid) to a cash collateral account in
                  respect of LOC Obligations, (B) with respect to all amounts
                  prepaid pursuant to Section 3.3(b)(ii), (iii), (iv) and (v),
                  pro rata to the Tranche A Term Loan and the Tranche B Term
                  Loan (in each case to the



                                       42
<PAGE>

                  remaining Principal Amortization Payments thereof in direct
                  order of maturity). Promptly upon notification thereof, one or
                  more holders of the Tranche B Term Loans may decline to accept
                  a mandatory prepayment under Section 3.3(b)(ii), (iii), (iv)
                  or (v) to the extent there are sufficient Tranche A Term Loans
                  outstanding to be paid with such prepayment, in which case,
                  such declined prepayments shall be allocated pro rata among
                  the Tranche A Term Loans and the Tranche B Term Loans held by
                  Lenders accepting such prepayments. Within the parameters of
                  the applications set forth above, prepayments shall be applied
                  first to Base Rate Loans and then to Eurodollar Loans in
                  direct order of Interest Period maturities. All prepayments
                  under this Section 3.3(b) shall be subject to Section 3.12.

         3.4      TERMINATION AND REDUCTION OF REVOLVING COMMITTED AMOUNT.

                  (a) VOLUNTARY REDUCTIONS. The Borrower may from time to time
         permanently reduce or terminate the Revolving Committed Amount in whole
         or in part (in minimum aggregate amounts of $1,000,000 or in integral
         multiples of $500,000 in excess thereof (or, if less, the full
         remaining amount of the then applicable Revolving Committed Amount))
         upon three Business Days prior written notice to the Agent; PROVIDED,
         HOWEVER, no such termination or reduction shall be made which would
         cause the aggregate principal amount of outstanding Revolving Loans
         PLUS LOC Obligations PLUS Swingline Loans outstanding to exceed the
         Revolving Committed Amount, unless, concurrently with such termination
         or reduction, the Revolving Loans are repaid to the extent necessary to
         eliminate such excess. The Agent shall promptly notify each affected
         Lender of receipt by the Agent of any notice from the Borrower pursuant
         to this Section 3.4(a).

                  (b) MATURITY DATE. The Revolving Commitments of the Lenders
         and the LOC Commitment of the Issuing Lender shall automatically
         terminate on the Maturity Date.

                  (c) GENERAL. The Borrower shall pay to the Agent for the
         account of the Lenders in accordance with the terms of Section 3.5(b),
         on the date of each termination or reduction of the Revolving Committed
         Amount, the Commitment Fee accrued through the date of such termination
         or reduction on the amount of the Revolving Committed Amount so
         terminated or reduced.

         3.5      FEES.

                  (a) COMMITMENT FEE. In consideration of the Revolving
         Commitments of the Lenders hereunder, the Borrower agrees to pay to the
         Agent for the account of each Lender a fee (the "COMMITMENT FEE") on
         the unused portion of the Revolving Committed Amount computed at a per
         annum rate for each day during the applicable Commitment Fee
         Calculation Period (hereinafter defined) at a rate equal to the
         Applicable Percentage in effect from time to time. The Commitment Fee
         shall commence to accrue on the Closing Date and shall be due and
         payable in arrears on the last business day of each February, May,
         August and November (and upon the Maturity Date) for the immediately
         preceding quarter (or portion thereof) (each such quarter or portion
         thereof for which the Commitment Fee is



                                       43
<PAGE>

         payable hereunder being herein referred to as an "COMMITMENT FEE
         CALCULATION PERIOD"), beginning with the first of such dates to occur
         after the Closing Date.

                  (b)      LETTER OF CREDIT FEES.

                                    (i) LETTER OF CREDIT ISSUANCE FEE. In
                           consideration of the issuance of Letters of Credit
                           hereunder, the Borrower promises to pay to the Agent
                           for the account of each Lender a fee (the "LETTER OF
                           CREDIT FEE") on such Lender's Revolving Commitment
                           Percentage of the average daily maximum amount
                           available to be drawn under each such Letter of
                           Credit computed at a per annum rate for each day from
                           the date of issuance to the date of expiration equal
                           to the Applicable Percentage (provided that the
                           Letter of Credit Fee shall not be less than $500 in
                           the aggregate for each Letter of Credit in any
                           event). The Letter of Credit Fee will be payable
                           quarterly in arrears on the last Business Day of each
                           February, May, August and November for the
                           immediately preceding quarter (or a portion thereof).

                                    (ii) ISSUING LENDER FEES. In addition to the
                           Letter of Credit Fee payable pursuant to clause (i)
                           above, the Borrower promises to pay to the Issuing
                           Lender for its own account without sharing by the
                           other Lenders the customary charges from time to time
                           of the Issuing Lender with respect to the issuance,
                           amendment, transfer, administration, cancellation and
                           conversion of, and drawings under, such Letters of
                           Credit (collectively, the "ISSUING LENDER FEES").

                  (c) ADMINISTRATIVE FEES. The Borrower agrees to pay to the
         Agent, for its own account, as applicable, the fees referred to in the
         Agent's Fee Letter (collectively, the "AGENT'S FEES").

         3.6      CAPITAL ADEQUACY.

         If any Lender has determined, after the date hereof, that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
upon notice from such Lender to the Borrower (such notice to be given within six
calendar months of the Lender's determination thereof) specifying in reasonable
detail the basis for the calculation of any additional amounts owed, the
Borrower shall be obligated to pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction. Each determination by
any such Lender of amounts



                                       44
<PAGE>

owing under this Section shall, absent manifest error, be conclusive and binding
on the parties hereto.

         3.7      LIMITATION ON EURODOLLAR LOANS.

         If on or prior to the first day of any Interest Period for any
Eurodollar Loan:

                  (a) the Agent determines (which determination shall be
         conclusive) that by reason of circumstances affecting the relevant
         market, adequate and reasonable means do not exist for ascertaining the
         Eurodollar Rate for such Interest Period; or

                  (b) the Required Lenders determine (which determination shall
         be conclusive) and notify the Agent that the Eurodollar Rate will not
         adequately and fairly reflect the cost to the Lenders of funding
         Eurodollar Loans for such Interest Period;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert Base
Rate Loans into Eurodollar Loans and the Borrower shall, on the last day(s) of
the then current Interest Period(s) for the outstanding Eurodollar Loans, either
prepay such Eurodollar Loans or Convert such Eurodollar Loans into Base Rate
Loans in accordance with the terms of this Credit Agreement.

         3.8      ILLEGALITY.

         Notwithstanding any other provision of this Credit Agreement, in the
event that it becomes unlawful for any Lender or its Applicable Lending Office
to make, maintain, or fund Eurodollar Loans hereunder, then such Lender shall
promptly notify the Borrower thereof and such Lender's obligation to make or
Continue Eurodollar Loans and to Convert Base Rate Loans into Eurodollar Loans
shall be suspended until such time as such Lender may again make, maintain, and
fund Eurodollar Loans (in which case the provisions of Section 3.10 shall be
applicable).

         3.9      REQUIREMENTS OF LAW.

         (a) If, after the date hereof, the adoption of any applicable law,
rule, or regulation, or any change in any applicable law, rule, or regulation,
or any change in the interpretation or administration thereof by any
Governmental Authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of law) of any such Governmental Authority, central bank, or
comparable agency:

                        (i) shall subject such Lender (or its Applicable Lending
         Office) to any tax, duty, or other charge with respect to any
         Eurodollar Loans, its Notes, or its obligation to make Eurodollar
         Loans, or change the basis of taxation of any amounts payable to such
         Lender (or its Applicable Lending Office) under this Credit Agreement
         or its Notes in respect of any Eurodollar Loans (other than taxes
         imposed on, or measured by, the overall net income or net capital of
         such Lender by the jurisdiction in which such Lender is



                                       45
<PAGE>

         organized, has its principal office or such Applicable Lending Office
         or is doing business (other than solely in connection with this Credit
         Agreement));

                       (ii) shall impose, modify, or deem applicable any
         reserve, special deposit, assessment, or similar requirement (other
         than the Eurodollar Reserve Requirement utilized in the determination
         of the Adjusted Eurodollar Rate) relating to any extensions of credit
         or other assets of, or any deposits with or other liabilities or
         commitments of, such Lender (or its Applicable Lending Office),
         including the Commitment of such Lender hereunder; or

                      (iii) shall impose on such Lender (or its Applicable
         Lending Office) or on the United States market for certificates of
         deposit or the London interbank market any other condition affecting
         this Credit Agreement or its Notes or any of such extensions of credit
         or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Loans or to reduce any sum received or receivable by
such Lender (or its Applicable Lending Office) under this Credit Agreement or
its Notes with respect to any Eurodollar Loans, then the Borrower shall pay to
such Lender on demand such amount or amounts as will compensate such Lender for
such increased cost or reduction. If any Lender requests compensation by the
Borrower under this Section 3.9(a), the Borrower may, by notice to such Lender
(with a copy to the Agent), suspend the obligation of such Lender to make or
Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar Loans,
until the event or condition giving rise to such request ceases to be in effect
(in which case the provisions of Section 3.10 shall be applicable); PROVIDED
that such suspension shall not affect the right of such Lender to receive the
compensation so requested.

         (b) Each Lender shall promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Lender to compensation pursuant to this Section 3.9 and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming
compensation under this Section 3.9 shall furnish to the Borrower and the Agent
a statement setting forth the additional amount or amounts to be paid to it
hereunder which shall be conclusive in the absence of manifest error. In
determining such amount, such Lender may use any reasonable averaging and
attribution methods.

         3.10     TREATMENT OF AFFECTED LOANS.

         If the obligation of any Lender to make any Eurodollar Loan or to
Continue, or to Convert Base Rate Loans into, Eurodollar Loans shall be
suspended pursuant to Section 3.8 or 3.9 hereof, such Lender's Eurodollar Loans
shall be automatically Converted into Base Rate Loans on the last day(s) of the
then current Interest Period(s) for such Eurodollar Loans (or, in the case of a
Conversion required by Section 3.8 hereof, on such earlier date as such Lender
may specify to the Borrower with a copy to the Agent) and, unless and until such
Lender gives notice as provided



                                       46
<PAGE>

         below that the circumstances specified in Section 3.8 or 3.9 hereof
         that gave rise to such Conversion no longer exist:

                  (a) to the extent that such Lender's Eurodollar Loans have
         been so Converted, all payments and prepayments of principal that would
         otherwise be applied to such Lender's Eurodollar Loans shall be applied
         instead to its Base Rate Loans; and

                  (b) all Loans that would otherwise be made or Continued by
         such Lender as Eurodollar Loans shall be made or Continued instead as
         Base Rate Loans, and all Base Rate Loans of such Lender that would
         otherwise be Converted into Eurodollar Loans shall remain as Base Rate
         Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 3.8 or 3.9 hereof that gave rise to the
Conversion of such Lender's Eurodollar Loans pursuant to this Section 3.10 no
longer exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when Eurodollar Loans made by other Lenders are
outstanding, such Lender's Base Rate Loans shall be automatically Converted, on
the first day(s) of the next succeeding Interest Period(s) for such outstanding
Eurodollar Loans, to the extent necessary so that, after giving effect thereto,
all Loans held by the Lenders holding Eurodollar Loans and by such Lender are
held pro rata (as to principal amounts, interest rate basis, and Interest
Periods) in accordance with their respective Commitments.

         3.11     TAXES.

                  (a) Any and all payments by the Borrower to or for the account
         of any Lender or the Agent hereunder or under any other Credit Document
         shall be made free and clear of and without deduction for any and all
         present or future taxes, duties, levies, imposts, deductions, charges
         or withholdings, and all liabilities with respect thereto, EXCLUDING,
         in the case of each Lender and the Agent, taxes imposed on, or measured
         by, its income or capital, and franchise taxes imposed on it, by the
         jurisdiction under the laws of which such Lender (or its Applicable
         Lending Office) or the Agent (as the case may be) is located or
         organized or in which such Lender or the Agent is doing business (other
         than solely by reason of this Agreement) or any political subdivision
         thereof (all such non-excluded taxes, duties, levies, imposts,
         deductions, charges, withholdings, and liabilities being hereinafter
         referred to as "TAXES"). If the Borrower shall be required by law to
         deduct any Taxes from or in respect of any sum payable under this
         Credit Agreement or any other Credit Document to any Lender or the
         Agent, (i) the sum payable shall be increased as necessary so that
         after making all required deductions (including deductions applicable
         to additional sums payable under this Section 3.11) such Lender or the
         Agent receives an amount equal to the sum it would have received had no
         such deductions been made, (ii) the Borrower shall make such
         deductions, (iii) the Borrower shall pay the full amount deducted to
         the relevant taxation authority or other authority in accordance with
         applicable law, and (iv) the Borrower shall furnish to the Agent, at
         its address referred to in Section 11.1, the original or a certified
         copy of a receipt evidencing payment thereof.



                                       47
<PAGE>

                  (b) In addition, the Borrower agrees to pay any and all
         present or future stamp or documentary taxes and any other excise or
         property taxes or charges or similar levies which arise from any
         payment made under this Credit Agreement or any other Credit Document
         or from the execution or delivery of, or otherwise with respect to,
         this Credit Agreement or any other Credit Document (hereinafter
         referred to as "OTHER TAXES").

                  (c) The Borrower agrees to indemnify each Lender and the Agent
         for the full amount of Taxes and Other Taxes (including, without
         limitation, any Taxes or Other Taxes imposed or asserted by any
         jurisdiction on amounts payable under this Section 3.11) paid by such
         Lender or the Agent (as the case may be) and any liability (including
         penalties, interest, and expenses) arising therefrom or with respect
         thereto.

                  (d) Each Lender and the Agent hereby represents that as of the
         Closing Date (or at such time as it becomes a Lender or the Agent, as
         the case may be, if later), all payments or principal, interest, and
         fees to be made to such Lender or the Agent, as the case may be, by the
         Borrower or any other Credit Party pursuant to this Agreement will be
         totally exempt from Taxes which would require indemnification under
         Section 3.11(a), 3.11(b) or 3.11(c). Each Lender organized under the
         laws of a jurisdiction outside the United States, on or prior to the
         date of its execution and delivery of this Credit Agreement in the case
         of each Lender listed on the signature pages hereof and on or prior to
         the date on which it becomes a Lender in the case of each other Lender,
         and from time to time thereafter if requested in writing by the
         Borrower or the Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Borrower and the Agent with complete
         and accurate copies of (i) Internal Revenue Service Form 1001 or 4224,
         as appropriate, or any successor form prescribed by the Internal
         Revenue Service, certifying that such Lender is entitled to benefits
         under an income tax treaty to which the United States is a party which
         reduces the rate of withholding tax on payments of interest or
         certifying that the income receivable pursuant to this Credit Agreement
         is effectively connected with the conduct of a trade or business in the
         United States, (ii) Internal Revenue Service Form W-8 or W-9, as
         appropriate, or any successor form prescribed by the Internal Revenue
         Service, and (iii) any other form or certificate required by any taxing
         authority (including any certificate required by Sections 871(h) and
         881(c) of the Internal Revenue Code), certifying that such Lender is
         entitled to an exemption from or a reduced rate of tax on payments
         pursuant to this Credit Agreement or any of the other Credit Documents.

                  (e) For any period with respect to which a Lender has failed
         to provide the Borrower and the Agent with the appropriate form
         pursuant to Section 3.11(d) (unless such failure is due to a change in
         treaty, law, or regulation occurring subsequent to the date on which a
         form originally was required to be provided), such Lender shall not be
         entitled to indemnification under Section 3.11(a), 3.11(b) or 3.11(c)
         with respect to Taxes imposed by the United States; PROVIDED, HOWEVER,
         that should a Lender, which is otherwise exempt from or subject to a
         reduced rate of withholding tax, become subject to Taxes because of its
         failure to deliver a form required hereunder, the Borrower shall take
         such steps as such Lender shall reasonably request to assist such
         Lender to recover such Taxes. The Borrower shall not be required to
         make gross-up or indemnification payments under Section 3.11(a),
         3.11(b) or 3.11(c) to any Lender or the Agent, as the



                                       48
<PAGE>

         case may be, to the extent that the obligation to pay such additional
         amounts or indemnification would not have arisen if the representation
         set forth in the first sentence of Section 3.11(d) were true with
         respect to such Lender or the Agent, as the case may be.

                  (f) If the Borrower is required to pay additional amounts to
         or for the account of any Lender pursuant to this Section 3.11, then
         such Lender will agree to use reasonable efforts to change the
         jurisdiction of its Applicable Lending Office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                  (g) Within thirty (30) days after the date of any payment of
         Taxes, the Borrower shall furnish to the Agent the original or a
         certified copy of a receipt evidencing such payment.

                  (h) Without prejudice to the survival of any other agreement
         of the Borrower hereunder, the agreements and obligations of the
         Borrower contained in this Section 3.11 shall survive the repayment of
         the Loans, LOC Obligations and other obligations under the Credit
         Documents and the termination of the Commitments hereunder.

                  (i) If any Lender or the Agent shall become aware that it is
         entitled to receive a refund in respect to Taxes as to which it has
         been indemnified by the Borrower pursuant to this Section 3.11, it
         shall promptly notify the Borrower of the availability of such refund
         and shall, within 30 days after receipt of a request by the Borrower,
         apply for such refund at the expense of the Borrower. If any Lender
         receives a refund in respect of any Taxes as to which it has been
         indemnified by the Borrower pursuant to this Section 3.11, it shall
         promptly notify the Borrower of such refund and shall, within 30 days
         after receipt of a request by the Borrower (or promptly upon receipt,
         if the Borrower has requested application for such refund pursuant
         hereto), repay such refund (including any interest actually received
         from the taxing authority with respect thereto) to the Borrower (to the
         extent of amounts that have been paid by the Borrower under this
         Section 3.11 with respect to such refund), net of all out-of-pocket
         expenses of such Lender and Taxes imposed with respect to such refund;
         PROVIDED that the Borrower, upon the request of such Lender, agrees to
         return such refund (plus penalties, interest or other charges) to such
         Lender in the event such Lender is required to repay such refund.
         Nothing contained in this subsection 3.11(i) shall require any Lender
         to make available any tax returns (or any other information relating to
         its taxes that it deems confidential).

         3.12     COMPENSATION.

         Upon the request of any Lender, the Borrower shall pay to such Lender
such amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense incurred by it as a
result of:

                  (a) any payment, prepayment, or Conversion of a Eurodollar
         Loan for any reason (including, without limitation, the acceleration of
         the Loans pursuant to Section 9.2) on a date other than the last day of
         the Interest Period for such Loan; or



                                       49
<PAGE>

                  (b) any failure by the Borrower for any reason (including,
         without limitation, the failure of any condition precedent specified in
         Section 5 to be satisfied) to borrow, Convert, Continue, or prepay a
         Eurodollar Loan on the date for such borrowing, Conversion,
         Continuation, or prepayment specified in the relevant notice of
         borrowing, prepayment, Continuation, or Conversion under this Credit
         Agreement.

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Eurodollar Loans provided for herein (excluding,
however, the Applicable Percentage included therein, if any) over (b) the amount
of interest (as reasonably determined by such Lender) which would have accrued
to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market. The covenants of
the Borrower set forth in this Section 3.12 shall survive the repayment of the
Loans, LOC Obligations and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

         3.13     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

                  (a) LOANS. Each Loan, each payment or (subject to the terms of
         Section 3.3) prepayment of principal of any Loan or reimbursement
         obligations arising from drawings under Letters of Credit, each payment
         of interest on the Loans or reimbursement obligations arising from
         drawings under Letters of Credit, each payment of Commitment Fees, each
         payment of the Letter of Credit Fee, each reduction of the Revolving
         Committed Amount and each conversion or extension of any Loan, shall be
         allocated pro rata among the Lenders in accordance with the respective
         principal amounts of their outstanding Loans and Participation
         Interests.

                  (b) ADVANCES. No Lender shall be responsible for the failure
         or delay by any other Lender in its obligation to make its ratable
         share of a borrowing hereunder; PROVIDED, HOWEVER, that the failure of
         any Lender to fulfill its obligations hereunder shall not relieve any
         other Lender of its obligations hereunder. Unless the Agent shall have
         been notified by any Lender prior to the date of any requested
         borrowing that such Lender does not intend to make available to the
         Agent its ratable share of such borrowing to be made on such date, the
         Agent may assume that such Lender has made such amount available to the
         Agent on the date of such borrowing, and the Agent in reliance upon
         such assumption, may (in its sole discretion but without any obligation
         to do so) make available to the Borrower a corresponding amount. If
         such corresponding amount is not in fact made available to the Agent,
         the Agent shall be able to recover such corresponding amount from such
         Lender. If such Lender does not pay such corresponding amount forthwith
         upon the Agent's demand therefor, the Agent will promptly notify the
         Borrower, and the Borrower shall immediately



                                       50
<PAGE>

         pay such corresponding amount to the Agent. The Agent shall also be
         entitled to recover from the Lender or the Borrower, as the case may
         be, interest on such corresponding amount in respect of each day from
         the date such corresponding amount was made available by the Agent to
         the Borrower to the date such corresponding amount is recovered by the
         Agent at a per annum rate equal to (i) from the Borrower at the
         applicable rate for the applicable borrowing pursuant to the Notice of
         Borrowing and (ii) from a Lender at the Federal Funds Rate.

         3.14     SHARING OF PAYMENTS.

         The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan, LOC Obligations or any other
obligation owing to such Lender under this Credit Agreement through the exercise
of a right of setoff, banker's lien or counterclaim, or pursuant to a secured
claim under Section 506 of Title 11 of the United States Code or other security
or interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Credit Agreement, such Lender shall promptly
purchase from the other Lenders a Participation Interest in such Loans, LOC
Obligations and other obligations in such amounts, and make such other
adjustments from time to time, as shall be equitable to the end that all Lenders
share such payment in accordance with their respective ratable shares as
provided for in this Credit Agreement. The Lenders further agree among
themselves that if payment to a Lender obtained by such Lender through the
exercise of a right of setoff, banker's lien, counterclaim or other event as
aforesaid shall be rescinded or must otherwise be restored, each Lender which
shall have shared the benefit of such payment shall, by repurchase of a
Participation Interest theretofore sold, return its share of that benefit
(together with its share of any accrued interest payable with respect thereto)
to each Lender whose payment shall have been rescinded or otherwise restored.
The Borrower agrees that any Lender so purchasing such a Participation Interest
may, to the fullest extent permitted by law, exercise all rights of payment,
including setoff, banker's lien or counterclaim, with respect to such
Participation Interest as fully as if such Lender were a holder of such Loan,
LOC Obligations or other obligation in the amount of such Participation
Interest. Except as otherwise expressly provided in this Credit Agreement, if
any Lender or the Agent shall fail to remit to the Agent or any other Lender an
amount payable by such Lender or the Agent to the Agent or such other Lender
pursuant to this Credit Agreement on the date when such amount is due, such
payments shall be made together with interest thereon for each date from the
date such amount is due until the date such amount is paid to the Agent or such
other Lender at a rate per annum equal to the Federal Funds Rate. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section 3.14 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 3.14 to share in the benefits of any recovery on such secured claim.

         3.15     PAYMENTS, COMPUTATIONS, ETC.

                  (a) Except as otherwise specifically provided herein, all
         payments hereunder shall be made to the Agent in dollars in immediately
         available funds, without offset, deduction, counterclaim or withholding
         of any kind, at the Agent's office specified in





                                       51
<PAGE>

         SCHEDULE 2.1(A) not later than 2:00 P.M. (Charlotte, North Carolina
         time) on the date when due. Payments received after such time shall be
         deemed to have been received on the next succeeding Business Day. The
         Agent may (but shall not be obligated to) debit the amount of any such
         payment which is not made by such time to any ordinary deposit account
         of the Borrower maintained with the Agent (with notice to the
         Borrower). The Borrower shall, at the time it makes any payment under
         this Credit Agreement, specify to the Agent the Loans, LOC Obligations,
         Fees, interest or other amounts payable by the Borrower hereunder to
         which such payment is to be applied (and in the event that it fails so
         to specify, or if such application would be inconsistent with the terms
         hereof, the Agent shall distribute such payment to the Lenders in such
         manner as the Agent may determine to be appropriate in respect of
         obligations owing by the Borrower hereunder, subject to the terms of
         Section 3.13(a)). The Agent will distribute such payments to such
         Lenders, if any such payment is received prior to 12:00 Noon
         (Charlotte, North Carolina time) on a Business Day in like funds as
         received prior to the end of such Business Day and otherwise the Agent
         will distribute such payment to such Lenders on the next succeeding
         Business Day. Whenever any payment hereunder shall be stated to be due
         on a day which is not a Business Day, the due date thereof shall be
         extended to the next succeeding Business Day (subject to accrual of
         interest and Fees for the period of such extension), except that in the
         case of Eurodollar Loans, if the extension would cause the payment to
         be made in the next following calendar month, then such payment shall
         instead be made on the next preceding Business Day. Except as expressly
         provided otherwise herein, all computations of interest and fees shall
         be made on the basis of actual number of days elapsed over a year of
         360 days. Interest shall accrue from and include the date of borrowing,
         but exclude the date of payment.

                  (b) ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.
         Notwithstanding any other provisions of this Credit Agreement to the
         contrary, after the occurrence and during the continuance of an Event
         of Default, all amounts collected or received by the Agent or any
         Lender on account of the Credit Party Obligations or any other amounts
         outstanding under any of the Credit Documents or in respect of the
         Collateral shall be paid over or delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Agent in connection with enforcing the rights of the Lenders
         under the Credit Documents and any protective advances made by the
         Agent with respect to the Collateral under or pursuant to the terms of
         the Collateral Documents;

                  SECOND, to payment of any fees owed to the Agent;

                  THIRD, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation, reasonable attorneys' fees)
         of each of the Lenders in connection with enforcing its rights under
         the Credit Documents or otherwise with respect to the Credit Party
         Obligations owing to such Lender;

                  FOURTH, to the payment of all of the Credit Party Obligations
         consisting of accrued fees and interest;



                                       52
<PAGE>

                  FIFTH, to the payment of the outstanding principal amount of
         the Credit Party Obligations (including the payment or cash
         collateralization of the outstanding LOC Obligations);

                  SIXTH, to all other Credit Party Obligations and other
         obligations which shall have become due and payable under the Credit
         Documents or otherwise and not repaid pursuant to clauses "FIRST"
         through "FIFTH" above; and

                  SEVENTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

         In carrying out the foregoing, (i) amounts received shall be applied in
         the numerical order provided until exhausted prior to application to
         the next succeeding category; (ii) each of the Lenders shall receive an
         amount equal to its pro rata share (based on the proportion that the
         then outstanding Loans and LOC Obligations held by such Lender bears to
         the aggregate then outstanding Loans and LOC Obligations) of amounts
         available to be applied pursuant to clauses "THIRD", "FOURTH", "FIFTH"
         and "SIXTH" above; and (iii) to the extent that any amounts available
         for distribution pursuant to clause "FIFTH" above are attributable to
         the issued but undrawn amount of outstanding Letters of Credit, such
         amounts shall be held by the Agent in a cash collateral account and
         applied (A) first, to reimburse the Issuing Lender from time to time
         for any drawings under such Letters of Credit and (B) then, following
         the expiration of all Letters of Credit, to all other obligations of
         the types described in clauses "FIFTH" and "SIXTH" above in the manner
         provided in this Section 3.15(b).

         3.16     EVIDENCE OF DEBT.

                  (a) Each Lender shall maintain an account or accounts
         evidencing each Loan made by such Lender to the Borrower from time to
         time, including the amounts of principal and interest payable and paid
         to such Lender from time to time under this Credit Agreement. Each
         Lender will make reasonable efforts to maintain the accuracy of its
         account or accounts and to promptly update its account or accounts from
         time to time, as necessary.

                  (b) The Agent shall maintain the Register pursuant to Section
         11.3(c), and a subaccount for each Lender, in which Register and
         subaccounts (taken together) shall be recorded (i) the amount, type and
         Interest Period of each such Loan hereunder, (ii) the amount of any
         principal or interest due and payable or to become due and payable to
         each Lender hereunder and (iii) the amount of any sum received by the
         Agent hereunder from or for the account of the Borrower and each
         Lender's share thereof. The Agent will make reasonable efforts to
         maintain the accuracy of the subaccounts referred to in the preceding
         sentence and to promptly update such subaccounts from time to time, as
         necessary.

                  (c) The entries made in the accounts, Register and subaccounts
         maintained pursuant to subsection (b) of this Section 3.16 (and, if
         consistent with the entries of the Agent, subsection (a)) shall be
         prima facie evidence of the existence and amounts of the



                                       53
<PAGE>

         obligations of the Borrower therein recorded; PROVIDED, HOWEVER, that
         the failure of any Lender or the Agent to maintain any such account,
         such Register or such subaccount, as applicable, or any error therein,
         shall not in any manner affect the obligation of the Borrower to repay
         the Loans made by such Lender in accordance with the terms hereof.


                                    SECTION 4

                                    GUARANTY

         4.1      THE GUARANTY.

         Each of the Guarantors hereby jointly and severally guarantees to each
Lender, each Affiliate of a Lender that enters into a Hedging Agreement, and the
Agent as hereinafter provided the prompt payment of the Credit Party Obligations
in full when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) strictly in
accordance with the terms thereof. The Guarantors hereby further agree that if
any of the Credit Party Obligations are not paid in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Credit Party
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

         Notwithstanding any provision to the contrary contained herein or in
any other of the Credit Documents or Hedging Agreements, the obligations of each
Guarantor hereunder shall be limited to an aggregate amount equal to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the Bankruptcy Code or any comparable provisions of any
applicable state law.



                                       54
<PAGE>




         4.2      OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors under Section 4.1 are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release, impairment or exchange of any other guarantee of or
security for any of the Credit Party Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
which might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 4.2 that the
obligations of the Guarantors hereunder shall be absolute and unconditional
under any and all circumstances. Each Guarantor agrees that such Guarantor shall
have no right of subrogation, indemnity, reimbursement or contribution against
the Borrower or any other Guarantor of the Credit Party Obligations for amounts
paid under this Section 4 until such time as the Lenders (and any Affiliates of
Lenders entering into Hedging Agreements) have been paid in full, all
Commitments under this Credit Agreement have been terminated and no Person or
Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Credit Documents or Hedging Agreements. Without limiting the generality of
the foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder which shall remain absolute and
unconditional as described above:

                  (a) at any time or from time to time, without notice to any
         Guarantor, the time for any performance of or compliance with any of
         the Credit Party Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (b) any of the acts mentioned in any of the provisions of any
         of the Credit Documents, any Hedging Agreement or any other agreement
         or instrument referred to in the Credit Documents or Hedging Agreements
         shall be done or omitted;

                  (c) the maturity of any of the Credit Party Obligations shall
         be accelerated, or any of the Credit Party Obligations shall be
         modified, supplemented or amended in any respect, or any right under
         any of the Credit Documents, any Hedging Agreement or any other
         agreement or instrument referred to in the Credit Documents or Hedging
         Agreements shall be waived or any other guarantee of any of the Credit
         Party Obligations or any security therefor shall be released, impaired
         or exchanged in whole or in part or otherwise dealt with;

                  (d) any Lien granted to, or in favor of, the Agent or any
         Lender or Lenders as security for any of the Credit Party Obligations
         shall fail to attach or be perfected; or

                  (e) any of the Credit Party Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of any Guarantor) or shall be subordinated to the claims
         of any Person (including, without limitation, any creditor of any
         Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the



                                       55
<PAGE>

Agent or any Lender exhaust any right, power or remedy or proceed against any
Person under any of the Credit Documents, any Hedging Agreement or any other
agreement or instrument referred to in the Credit Documents or Hedging
Agreements, or against any other Person under any other guarantee of, or
security for, any of the Credit Party Obligations.

         4.3      REINSTATEMENT.

         The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, fees and expenses of counsel) incurred by the
Agent or such Lender in connection with such rescission or restoration,
including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or
similar payment under any bankruptcy, insolvency or similar law.

         4.4      CERTAIN ADDITIONAL WAIVERS.

         Without limiting the generality of the provisions of this Section 4,
each Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. ss.ss.
26-7 through 26-9, inclusive, to the extent applicable. Each Guarantor further
agrees that such Guarantor shall have no right of recourse to security for the
Credit Party Obligations, except through the exercise of rights of subrogation
pursuant to Section 4.2 and through the exercise of rights of contribution
pursuant to Section 4.6.

         4.5      REMEDIES.

         The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agent and the Lenders, on the
other hand, the Credit Party Obligations may be declared to be forthwith due and
payable as provided in Section 9.2 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 9.2)
for purposes of Section 4.1 notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing the Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Credit Party
Obligations being deemed to have become automatically due and payable), the
Credit Party Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of Section
4.1. The Guarantors acknowledge and agree that their obligations hereunder are
secured in accordance with the terms of the Security Agreements and the other
Collateral Documents and that the Lenders may exercise their remedies thereunder
in accordance with the terms thereof.

         4.6      RIGHTS OF CONTRIBUTION.

         The Guarantors hereby agree as among themselves that, if any Guarantor
shall make an Excess Payment (as defined below), such Guarantor shall have a
right of contribution from each



                                       56
<PAGE>

other Guarantor in an amount equal to such other Guarantor's Contribution Share
(as defined below) of such Excess Payment. The payment obligations of any
Guarantor under this Section 4.6 shall be subordinate and subject in right of
payment to the prior payment in full to the Agent and the Lenders of the
Guaranteed Obligations, and none of the Guarantors shall exercise any right or
remedy under this Section 4.6 against any other Guarantor until payment and
satisfaction in full of all of such Guaranteed Obligations. For purposes of this
Section 4.6, (a) "GUARANTEED OBLIGATIONS" shall mean any obligations arising
under the other provisions of this Section 4; (b) "EXCESS PAYMENT" shall mean
the amount paid by any Guarantor in excess of its Pro Rata Share of any
Guaranteed Obligations; (c) "PRO RATA SHARE" shall mean, for any Guarantor in
respect of any payment of Guaranteed Obligations, the ratio (expressed as a
percentage) as of the date of such payment of Guaranteed Obligations of (i) the
amount by which the aggregate present fair salable value of all of its assets
and properties exceeds the amount of all debts and liabilities of such Guarantor
(including contingent, subordinated, unmatured, and unliquidated liabilities,
but excluding the obligations of such Guarantor hereunder) to (ii) the amount by
which the aggregate present fair salable value of all assets and other
properties of the Borrower and all of the Guarantors exceeds the amount of all
of the debts and liabilities (including contingent, subordinated, unmatured, and
unliquidated liabilities, but excluding the obligations of the Borrower and the
Guarantors hereunder) of the Borrower and all of the Guarantors; PROVIDED,
HOWEVER, that, for purposes of calculating the Pro Rata Shares of the Guarantors
in respect of any payment of Guaranteed Obligations, any Guarantor that became a
Guarantor subsequent to the date of any such payment shall be deemed to have
been a Guarantor on the date of such payment and the financial information for
such Guarantor as of the date such Guarantor became a Guarantor shall be
utilized for such Guarantor in connection with such payment; and (d)
"CONTRIBUTION SHARE" shall mean, for any Guarantor in respect of any Excess
Payment made by any other Guarantor, the ratio (expressed as a percentage) as of
the date of such Excess Payment of (i) the amount by which the aggregate present
fair salable value of all of its assets and properties exceeds the amount of all
debts and liabilities of such Guarantor (including contingent, subordinated,
unmatured, and unliquidated liabilities, but excluding the obligations of such
Guarantor hereunder) to (ii) the amount by which the aggregate present fair
salable value of all assets and other properties of the Borrower and all of the
Guarantors other than the maker of such Excess Payment exceeds the amount of all
of the debts and liabilities (including contingent, subordinated, unmatured, and
unliquidated liabilities, but excluding the obligations of the Borrower and the
Guarantors hereunder) of the Borrower and all of the Guarantors other than the
maker of such Excess Payment; PROVIDED, HOWEVER, that, for purposes of
calculating the Contribution Shares of the Guarantors in respect of any Excess
Payment, any Guarantor that became a Guarantor subsequent to the date of any
such Excess Payment shall be deemed to have been a Guarantor on the date of such
Excess Payment and the financial information for such Guarantor as of the date
such Guarantor became a Guarantor shall be utilized for such Guarantor in
connection with such Excess Payment. This Section 4.6 shall not be deemed to
affect any right of subrogation, indemnity, reimbursement or contribution that
any Guarantor may have under applicable law against the Borrower in respect of
any payment of Guaranteed Obligations. Notwithstanding the foregoing, all rights
of contribution against any Guarantor shall terminate from and after such time,
if ever, that such Guarantor shall be relieved of its obligations pursuant to
Section 8.4.

         4.7      CONTINUING GUARANTEE.

         The guarantee in this Section 4 is a guaranty of payment and not of
collection, is a continuing guarantee, and shall apply to all Credit Party
Obligations whenever arising.


                                    SECTION 5

                                   CONDITIONS

         5.1      CLOSING CONDITIONS.

         The obligation of the Lenders to enter into this Credit Agreement and
to make the initial Loans or the Issuing Lender to issue the initial Letter of
Credit, whichever shall occur first, shall be subject to satisfaction of the
following conditions (in form and substance acceptable to the Lenders):

<PAGE>

         results of operations, retained earnings and cash flows for the
         Acquired Company and its Subsidiaries for the dates and periods therein

         Consolidated Parties as of the Closing Date giving effect to the
         Acquisition in accordance with the terms of the Purchase Agreement and

         respect.

         and for such periods in the case of the financial statements referred

with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

         6.11     ERISA.

                  (a) During the five-year period prior to the date on which
         this representation is made or deemed made: (i) no ERISA Event has
         occurred, and, to the best knowledge of the Credit Parties, no event or
         condition has occurred or exists as a result of which any ERISA Event
         could reasonably be expected to occur, with respect to any Plan; (ii)
         no "accumulated funding deficiency," as such term is defined in Section

         under each Single Employer Plan, as of the last annual valuation date
         prior to the date on which this representation is made or deemed made
         (determined, in each case, utilizing the actuarial assumptions used in
         such Plan's most



                                       68

         incurred, or, to the best knowledge of the Credit Parties, could be
         reasonably expected to incur, any withdrawal liability under ERISA to
         any Multiemployer Plan or Multiple Employer Plan. Neither any
         Consolidated Party nor any ERISA Affiliate would become subject to any
         withdrawal liability under ERISA if any Consolidated Party or any ERISA
         Affiliate were to withdraw completely from all Multiemployer Plans and

         notification that any Multiemployer Plan is in reorganization (within
         the meaning of Section 4241 of ERISA), is insolvent (within the meaning
         of Section 4245 of ERISA), or has been terminated (within the meaning
         of Title IV of ERISA), and no Multiemployer Plan is, to the best
         knowledge of the Credit Parties, reasonably expected to be in
         reorganization, insolvent, or terminated.

                  (d) No prohibited transaction (within the meaning of Section
         406 of ERISA or Section 4975 of the Code) or breach of fiduciary
         responsibility has occurred with respect to a Plan which has subjected
         or may subject any Consolidated Party or any ERISA Affiliate to any
         material liability under Sections 406, 409, 502(i), or 502(l) of ERISA
         or Section 4975 of the Code, or under any agreement or other instrument
         pursuant to which any Consolidated Party or any ERISA Affiliate has
         agreed or is required to indemnify any person against any such
         liability.

                  (e) Neither any Consolidated Party nor any ERISA Affiliates
         has any material liability with respect to "expected post-retirement
         benefit obligations" within the meaning of the Financial Accounting
         Standards Board Statement 106.

indirectly, free and clear of all Liens (other than those arising under or
contemplated in connection with the Credit Documents). Neither the Borrower nor
any other Consolidated Party, other than as set forth in SCHEDULE 6.12, has
outstanding any securities convertible into or exchangeable for its Capital
Stock nor does any such Person have outstanding any rights to subscribe for or
to purchase or any options for the purchase of, or any agreements providing for
the issuance (contingent or otherwise) of, or any calls, commitments or claims
of any character relating to its Capital Stock. SCHEDULE 6.12 may be updated
from time to time by the Borrower by giving written notice thereof to the Agent.

         6.13     GOVERNMENTAL REGULATIONS, ETC.

                  (a) No part of the Letters of Credit or proceeds of the Loans
         will be used, directly or indirectly, for the purpose of purchasing or
         carrying any "margin stock" within the meaning of Regulation U, or for
         the purpose of purchasing or carrying or trading in any securities
         except as contemplated in connection with the purchase of the Acquired
         Company or the securities of any other Subsidiary of the Borrower. If
         requested by any Lender or the Agent, the Borrower will furnish to the
         Agent and each Lender a statement to the foregoing effect in conformity
         with the requirements of FR Form U-1 referred to in Regulation U. No
         indebtedness being reduced or retired out of the proceeds of the Loans
         was or will be incurred for the purpose of purchasing or carrying any
         margin stock within the meaning of Regulation U or any "margin
         security" within the meaning of Regulation T. "Margin stock" within the
         meaning of Regulation U does not constitute more than 25% of the value
         of the consolidated assets of the Consolidated Parties. None of the
         transactions contemplated by this Credit Agreement (including, without
         limitation, the direct or indirect use of the proceeds of the Loans)
         will violate or result in a violation of the Securities Act of 1933, as
         amended, or the Securities Exchange Act of 1934, as amended, or
         regulations issued pursuant thereto, or Regulation T, U or X.

                  (b) No Consolidated Party is subject to regulation under the
         Public Utility Holding Company Act of 1935, the Federal Power Act or
         the Investment Company Act of 1940, each as amended. In addition, no
         Consolidated Party is (i) an "investment company" registered or
         required to be registered under the Investment Company Act of 1940, as
         amended, and is not controlled by such a company, or (ii) a "holding
         company", or a "subsidiary company" of a "holding company", or an
         "affiliate" of a "holding company" or of a "subsidiary" of a "holding
         company", within the meaning of the Public Utility Holding Company Act
         of 1935, as amended.

                  (c) No director, executive officer or principal shareholder of
         any Consolidated Party is a director, executive officer or principal
         shareholder of any Lender. For the purposes hereof the terms
         "director", "executive officer" and "principal shareholder" (when used
         with reference to any Lender) have the respective meanings assigned
         thereto in Regulation O issued by the Board of Governors of the Federal
         Reserve System.

                  (d) Each Consolidated Party has obtained and holds in full
         force and effect, all material franchises, licenses, permits,
         certificates, authorizations, qualifications, accreditations,
         easements, rights of way and other rights, consents and approvals which
         are necessary for the ownership of its respective Property and to the
         conduct of its respective businesses as presently conducted.

                  (e) To the best of each Consolidated Party's knowledge, each
         Consolidated Party is current with all material reports and documents,
         if any, required to be filed with any state or federal securities
         commission or similar agency and is in full compliance in all material
         respects with all applicable rules and regulations of such commissions.

         The Borrower has (i) initiated a review and assessment of all areas
within its and each of its Subsidiaries' business and operations (including

be able to perform properly date-sensitive functions for all dates before and
after January 1, 2000 (that is, be "Year 2000 compliant"), except to the extent
that a failure to do so could not reasonably be expected to have Material
Adverse Effect.

HOWEVER, that no Consolidated Party shall be required to pay any such tax,
assessment, charge, levy, claim or Indebtedness which is being contested in good
faith by appropriate proceedings and as to which adequate reserves therefor have
been established in accordance with GAAP, unless the failure to make any such
payment (i) could give rise to an immediate right to foreclose on a Lien
securing such amounts or (ii) could reasonably be expected to have a Material
Adverse Effect.

         7.6      INSURANCE.

                  (a) Each Credit Party will, and will cause each of its
         Subsidiaries to, at all times maintain in full force and effect
         insurance (including worker's compensation insurance, liability
         insurance, casualty insurance and business interruption insurance) in
         such amounts, covering such risks and liabilities and with such
         deductibles or self-insurance retentions as are in accordance with
         normal industry practice. The Agent shall be named as loss payee or
         mortgagee, as its interest may appear, and/or additional insured with
         respect to any



                                       78
<PAGE>

         such insurance providing coverage in respect of any Collateral, and
         each provider of any such insurance shall agree, by endorsement upon
         the policy or policies issued by it or by independent instruments
         furnished to the Agent, that it will give the Agent thirty (30) days
         prior written notice before any such policy or policies shall be
         altered or canceled, and that no act or default of any Consolidated
         Party or any other Person shall affect the rights of the Agent or the
         Lenders under such policy or policies. The present insurance coverage
         of the Consolidated Parties is outlined as to carrier, policy number,
         expiration date, type and amount on SCHEDULE 7.6.

                  (b) In case of any material loss, damage to or destruction of
         the Collateral of any Credit Party or any part thereof, such Credit
         Party shall promptly give written notice thereof to the Agent generally
         describing the nature and extent of such damage or destruction. In case
         of any loss, damage to or destruction of the Collateral of any Credit
         Party or any part thereof, such Credit Party, whether or not the
         insurance proceeds, if any, received on account of such damage or
         destruction shall be sufficient for that purpose, at such Credit
         Party's cost and expense, will promptly repair or replace the
         Collateral of such Credit Party so lost, damaged or destroyed;
         PROVIDED, HOWEVER, that such Credit Party need not repair or replace
         the Collateral of such Credit Party so lost, damaged or destroyed to
         the extent the failure to make such repair or replacement (i)
         determined by the board of directors of the Borrower to be desirable to
         the proper conduct of the business of such Credit Party in the ordinary
         course and otherwise in the best interest of such Credit Party; and
         (ii) would not materially impair the rights of the Agent or the Lenders
         under the Collateral Documents, any other Credit Document or any
         Hedging Agreement. In the event a Credit Party shall receive net
         proceeds of such insurance in excess of $1,000,000, such Credit Party
         will immediately pay over such proceeds to the Agent, for payment on
         the Credit Party Obligations for application as an Asset Disposition as
         set forth in Section 3.3(b)(iii); PROVIDED, HOWEVER, that the Agent
         agrees to release such insurance proceeds to such Credit Party for
         replacement or restoration of the portion of the Collateral of such
         Credit Party lost, damaged or destroyed (including reimbursement of any
         Credit Party for expenditures previously made therefore) if, but only
         if, (A) no Default or Event of Default shall have occurred and be
         continuing at the time of release, (B) written application for such
         release is received by the Agent from such Credit Party within 30 days
         of receipt of such proceeds and (C) the Agent has received evidence
         reasonably satisfactory to it that the Collateral lost, damaged or
         destroyed has been or will be replaced or restored to reasonable
         condition within 180 days after the date such Collateral was lost,
         damaged or destroyed.

         7.7      MAINTENANCE OF PROPERTY.

         Each Credit Party will, and will cause each of its Subsidiaries to,
maintain and preserve its properties and equipment material to the conduct of
its business in reasonable repair, working order and condition, normal wear and
tear and casualty and condemnation excepted, and will make, or cause to be made,
in such properties and equipment from time to time all repairs, renewals,
replacements, extensions, additions, betterments and improvements thereto as may
be needed or proper in the reasonable conduct of its business, to the extent and
in the manner customary for companies in similar businesses.

         7.8      PERFORMANCE OF OBLIGATIONS.

         Except as could not reasonably be expected to result in a Material
Adverse Effect, each Credit Party will, and will cause each of its Subsidiaries
to, perform in all material respects all of its obligations under the terms of
all material agreements, indentures, mortgages, security agreements or other
debt instruments to which it is a party or by which it is bound.

         7.9      USE OF PROCEEDS.

         The Borrower will use the proceeds of the Loans and will use the
Letters of Credit solely for the purposes set forth in Section 6.14.

         7.10     AUDITS/INSPECTIONS.

         Upon reasonable notice, during normal business hours and without undue
disruption, each Credit Party will, and will cause each of its Subsidiaries to,
permit representatives appointed by the Agent, including, without limitation,
independent accountants, agents, attorneys, and appraisers to visit and inspect
its property, including its books and records, its accounts receivable and
inventory, its facilities and its other business assets, and to make photocopies
or photographs thereof and to write down and record any information such
representative obtains and shall permit the Agent or its representatives to
investigate and verify the accuracy of information provided to the Lenders and
to discuss all such matters with the officers, employees and representatives of
such Person. All information obtained pursuant to this Section 7.10 shall be
subject to the provisions of Section 11.16. The Credit Parties agree that the
Agent, and its representatives, may conduct an annual audit of the Collateral,
at the expense of the Borrower. Notwithstanding the foregoing, the rights of the
Lenders and the Agent under this Section 7.10 shall be subject to restrictions
on access to the Credit Parties' information and facilities under laws and
regulations applicable to the Credit Parties', including without limitations any
laws or regulations governing national security matters, security clearances or
the like.

with written notice thereof setting forth information in reasonable detail
describing all of the assets of such Person and shall (a) if such Person is a
Domestic Subsidiary of a Credit Party, cause such Person to execute a Joinder
Agreement in substantially the same form as EXHIBIT 7.12, (b) cause 100% (if
such Person is a Domestic Subsidiary of a Credit Party) or 65% (if such Person
is a direct Foreign Subsidiary of the Borrower or a Domestic Subsidiary) of the
Capital Stock of such Person to be delivered to the Agent (together with undated
stock powers signed in blank (unless, with respect to a Foreign Subsidiary, such
stock powers are deemed unnecessary by the Agent in its reasonable discretion
under the law of the jurisdiction of incorporation of such Person)) and pledged
to the Agent pursuant to an appropriate pledge agreement(s) in substantially the
form of the Pledge Agreement and otherwise in form acceptable to the Agent and
(c) cause such Person (if such Person is a Domestic Subsidiary) to (i) if such
Person owns or leases any real property located in the United States of America
or deemed to be material by the Agent or the Required Lenders in its or their
sole reasonable discretion, deliver to the Agent with respect to such real
property documents, instruments and other items of the types required to be
delivered by the Agent all in form, content and scope reasonably satisfactory to
the Agent and (ii) deliver such other documentation as the Agent may reasonably
request in connection with the foregoing, including, without limitation,
appropriate UCC-1 financing statements, real estate title insurance policies,
environmental reports, landlord's waivers, certified resolutions and other
organizational and authorizing documents of such Person, favorable opinions of
counsel to such Person (which shall cover, among other things, the legality,
validity, binding effect and enforceability of the documentation referred to
above and the perfection of the Agent's liens thereunder) and other items of the
types required to be delivered pursuant to Section 5.1(f), all in form, content
and scope reasonably satisfactory to the Agent.

         7.13     PLEDGED ASSETS.

         Each Credit Party will, and will cause each of its Domestic
Subsidiaries to, cause (i) all of its owned real and personal property located
in the United States, (ii) to the extent deemed to be material by the Agent or
the Required Lenders in its or their sole reasonable discretion, all of its
other owned real and personal property and (iii) to the extent deemed material

all of its leased real property located in the United States, to be subject at
all times to first priority, perfected and, in the case of real property
(whether leased or owned), title insured Liens in favor of the Agent pursuant to
the terms and conditions of the Collateral Documents or, with respect to any
such property acquired subsequent to the Closing Date, such other additional
security documents as the Agent shall reasonably request; PROVIDED, HOWEVER that
upon the Borrower's request, the Agent may in its reasonable discretion, waive
certain of the requirements hereunder if it is determined that the



                                       82
<PAGE>

costs of compliance with the provisions hereof are excessive in light of the
benefit to be obtained in connection therewith. With respect to any real
property (whether leased or owned) located in the United States of America
acquired by any direct or indirect Domestic Subsidiary of the Borrower
subsequent to the Closing Date, such Person will cause to be delivered to the
Agent with respect to such real property documents, instruments and other items
of the types required to be delivered pursuant to Section 5.1(h) in form
acceptable to the Agent. In furtherance of the foregoing terms of this Section
7.13, the Borrower agrees to promptly provide the Agent with written notice of
the acquisition by, or the entering into a leasing by, any Credit Party of any
asset(s) having a market value greater than $500,000, setting forth in
reasonable detail the location and a description of the asset(s) so acquired.
Without limiting the generality of the above, the Credit Parties will cause 100%
of the Capital Stock of the Borrower and each other direct or indirect Domestic
Subsidiaries of the Borrower and 65% of the Capital Stock in each of the direct
Foreign Subsidiaries of the Borrower and its Domestic Subsidiaries to be subject
at all times to a first priority, perfected Lien in favor of the Agent pursuant
to the terms and conditions of the Collateral Documents or such other security
documents as the Agent shall reasonably request.

         If, subsequent to the Closing Date, a Credit Party shall (a) acquire
any intellectual property, securities, instruments, chattel paper or other
personal property required to be delivered to the Agent as Collateral hereunder
or under any of the Collateral Documents or (b) acquire or lease any real
property, the Borrower shall promptly (and in any event within three (3)
Business Days) after any Executive Officer of a Credit Party acquires knowledge
of same notify the Agent of same. Each Credit Party shall, and shall cause each
of its Subsidiaries to, take such action (including but not limited to the
actions set forth in Sections 5.1(f) and 5.1(i) at its own expense as requested
by the Agent to ensure that the Agent has a first priority perfected Lien to
secure the Credit Party Obligations in (i) all owned real property and personal
property of the Credit Parties located in the United States, (ii) to the extent
deemed to be material by the Agent or the Required Lenders in its or their sole
reasonable discretion, all other owned real and personal property of the Credit
Parties and (iii) to the extent deemed material by the Agent or the Required
Lenders in its or their sole reasonable discretion, all leased real property
located in the United States, subject in each case only to Permitted Liens. Each
Credit Party shall, and shall cause each of its Domestic Subsidiaries to, adhere
to the covenants regarding the location of personal property as set forth in the
Security Agreements.

         7.14     YEAR 2000 COMPLIANCE.

         The Borrower will promptly notify the Agent in the event that the
Borrower discovers or determines that any computer application (including those
of its suppliers and vendors) that is material to its or any of its Subsidiaries
business and operations will not be Year 2000 compliant (as such term is defined
in Section 6.25), except to the extent that such failure could not reasonably be
expected to have a Material Adverse Effect.

         7.15     ANNUAL MEETING.

         The Borrower will assist the Agent in organizing an annual bank meeting
where members of management will be available to meet with representatives of
the Lenders.

         7.16     NAME CHANGE DOCUMENTATION.

         As soon as practicable, but in any event within 5 Business Days after
the Closing Date, the Credit Parties shall have filed all documentation
applicable and/or appropriate in all relevant jurisdictions to effectuate each
relevant name change as required under the Purchase Agreement for each of the
Designated Corporations.

         7.17     IRB FACILITY.

         As soon as practicable, but in any event within 45 days after the
Closing Date, the Credit Parties shall have either (i) obtained the consent of
the First National Bank of Maryland, as trustee under the Illinois IRB, to the
transfer of the Capital Stock of Mark Antenna Products, Inc. from CRSI, Inc. to
the Borrower, in which case, the Credit Parties may maintain and continue the
industrial revenue bond facility until October 15, 1998, upon which time, the
industrial revenue bond facility shall be terminated and the real and personal
property assets securing the loan agreement in connection with the same shall be
pledged to secure the Credit Party Obligations or (ii) failed to obtain the
consent of the First National Bank of Maryland to the transfer of the Capital
Stock of Mark Antenna Products, Inc., terminated the industrial revenue bond
facility and pledged the real and personal property assets securing the loan
agreement in connection with such facility to secure the Credit Party
Obligations.

reasonably satisfactory to the Agent of the real property assets owned by any
Credit Party located in Catawba County, North Carolina.

         7.19     INTEREST RATE PROTECTION.

         Within 180 days after the Closing Date, the Borrower shall have entered
into interest rate protection agreements protecting against fluctuations in
interest rates as to which the material terms are reasonably satisfactory to the
Agent, which agreements shall provide coverage in an amount and for a duration
satisfactory to the Agent.

                               NEGATIVE COVENANTS

         other Credit Documents;

         instrument or agreement evidencing, securing or relating thereto, or
         any other event or condition shall occur or condition exist, the effect
         of which default or other event or condition is to cause, or permit,
         the holder or holders of such Indebtedness (or trustee or agent on
         behalf of such holders) to cause (determined without regard to whether
         any notice or lapse of time is required), any such Indebtedness to
         become due prior to its stated maturity; or (B) any such Indebtedness
         shall be declared due and payable, or required to be prepaid other than
         by a regularly scheduled required prepayment, prior to the stated
         maturity thereof; or

         liability of $1,000,000 or more in the aggregate (to the extent not
         paid or fully covered by insurance provided by a carrier who has
         acknowledged coverage and has the ability to perform) and any such
         judgments or decrees shall not have been vacated, discharged or stayed

         favor of the PBGC or a Plan; (ii) an ERISA Event shall occur with
         respect to a Single Employer Plan, which is, in the reasonable opinion
         of the Agent, likely to result in the termination of such Plan for
         purposes of Title IV of ERISA; (iii) an ERISA Event shall occur with
         respect to a Multiemployer Plan or Multiple Employer Plan, which is, in
         the reasonable opinion of the Agent, likely to result in (A) the
         termination of such Plan for purposes of Title IV of ERISA, or (B) any
         Consolidated Party or any ERISA Affiliate incurring any liability in
         connection with a withdrawal from, reorganization of (within the

         under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of
         the Code, or under any agreement or other instrument pursuant to which

         the Consolidated Parties in excess of $7,000,000.

         9.2      ACCELERATION; REMEDIES.

         Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite Lenders
(pursuant to the voting requirements of Section 11.6) or cured to the
satisfaction of the requisite Lenders (pursuant to the voting procedures in
Section 11.6), the Agent may, with the consent of the Required Lenders, and the
Agent shall, upon the request and direction of the Required Lenders, by written
notice to the Credit Parties take any of the following actions:

                  (a) TERMINATION OF COMMITMENTS. Declare the Commitments
         terminated whereupon the Commitments shall be immediately terminated.

                  (b) ACCELERATION. Declare the unpaid principal of and any
         accrued interest in respect of all Loans, any reimbursement obligations
         arising from drawings under Letters of Credit and any and all other
         indebtedness or obligations of any and every kind owing by the Borrower
         to the Agent and/or any of the Lenders hereunder to be due whereupon
         the same shall be immediately due and payable without presentment,
         demand, protest or other notice of any kind, all of which are hereby
         waived by the Borrower.

                  (c) CASH COLLATERAL. Direct the Borrower to pay (and the
         Borrower agrees that upon receipt of such notice, or upon the
         occurrence of an Event of Default under Section 9.1(f), it will
         immediately pay) to the Agent additional cash, to be held by the Agent,
         for the benefit of the Lenders, in a cash collateral account as
         additional security for the LOC Obligations in respect of subsequent
         drawings under all then outstanding Letters of Credit in an amount
         equal to the maximum aggregate amount which may be drawn under all
         Letters of Credits then outstanding.

                  (d) ENFORCEMENT OF RIGHTS. Enforce any and all rights and
         interests created and existing under the Credit Documents including,
         without limitation, all rights and remedies existing under the
         Collateral Documents, all rights and remedies against a Guarantor and
         all rights of set-off.

         Notwithstanding the foregoing, if an Event of Default specified in
Section 9.1(f) shall occur, then the Commitments shall automatically terminate
and all Loans, all reimbursement obligations arising from drawings under Letters
of Credit, all accrued interest in respect thereof, all accrued and unpaid Fees
and other indebtedness or obligations owing to the Agent and/or any of the
Lenders hereunder automatically shall immediately become due and payable without
the giving of any notice or other action by the Agent or the Lenders. If an
Event of Default occurs, all U.S. and foreign government classified information
in possession of any Credit Party shall remain the property of the U.S.
Government and the applicable foreign government(s).

In the event that the Agent determines to commence foreclosure proceedings under
any of the Credit Documents, or the Agent is instructed by the Required Lenders
to do so, the Agent will promptly deliver (by hand delivery or facsimile
transmission) to the U.S. Department of Defense, Defense Security Service, at
1340 Braddock Place, Alexandria, Virginia, Facsimile No.: (703) 325-1329,
Attention: Valerie Heil, notice of such determination, or a copy of such
instructions. The



                                       94
<PAGE>

Agent will not commence such foreclosure proceedings earlier than the day
following the fifth Business Day after the date that such notice was sent to the
Defense Security Service (including the date the notice was sent) as provided
above unless instructed otherwise by the Required Lenders. Notwithstanding
anything to the contrary therein, each Credit Document shall be subject to the
foregoing provisions of this Section 9.2.


                                   SECTION 10

                                AGENCY PROVISIONS

         10.1     APPOINTMENT, POWERS AND IMMUNITIES.

         Each Lender hereby irrevocably appoints and authorizes the Agent to act
as its agent under this Credit Agreement and the other Credit Documents with
such powers and discretion as are specifically delegated to the Agent by the
terms of this Credit Agreement and the other Credit Documents, together with
such other powers as are reasonably incidental thereto. The Agent (which term as
used in this sentence and in Section 10.5 and the first sentence of Section 10.6
hereof shall include its Affiliates and its own and its Affiliates' officers,
directors, employees, and agents): (a) shall not have any duties or
responsibilities except those expressly set forth in this Credit Agreement and
shall not be a trustee or fiduciary for any Lender; (b) shall not be responsible
to the Lenders for any recital, statement, representation, or warranty (whether
written or oral) made in or in connection with any Credit Document or any
certificate or other document referred to or provided for in, or received by any
of them under, any Credit Document, or for the value, validity, effectiveness,
genuineness, enforceability, or sufficiency of any Credit Document, or any other
document referred to or provided for therein or for any failure by any Credit
Party or any other Person to perform any of its obligations thereunder; (c)
shall not be responsible for or have any duty to ascertain, inquire into, or
verify the performance or observance of any covenants or agreements by any
Credit Party or the satisfaction of any condition or to inspect the property
(including the books and records) of any Credit Party or any of its Subsidiaries
or Affiliates; (d) shall not be required to initiate or conduct any litigation
or collection proceedings under any Credit Document; and (e) shall not be
responsible for any action taken or omitted to be taken by it under or in
connection with any Credit Document, except for its own gross negligence or
willful misconduct. The Agent may employ agents and attorneys-in-fact and shall
not be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.

         10.2     RELIANCE BY AGENT.

         The Agent shall be entitled to rely upon any certification, notice,
instrument, writing, or other communication (including, without limitation, any
thereof by telephone or telecopy) believed by it to be genuine and correct and
to have been signed, sent or made by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel (including counsel for
any Credit Party), independent accountants, and other experts selected by the
Agent. The Agent may deem and treat the payee of any Note as the holder thereof
for all purposes hereof unless and until the Agent receives and accepts an
Assignment and Acceptance executed in



                                       95
<PAGE>

accordance with Section 11.3(b) hereof. As to any matters not expressly provided
for by this Credit Agreement, the Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Required Lenders, and such instructions shall be
binding on all of the Lenders; PROVIDED, HOWEVER, that the Agent shall not be
required to take any action that exposes the Agent to personal liability or that
is contrary to any Credit Document or applicable law or unless it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking any such action.

         10.3     DEFAULTS.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of a Default or Event of Default unless the Agent has received
written notice from a Lender or the Borrower specifying such Default or Event of
Default and stating that such notice is a "Notice of Default". In the event that
the Agent receives such a notice of the occurrence of a Default or Event of
Default, the Agent shall give prompt notice thereof to the Lenders. The Agent
shall (subject to Section 10.2 hereof) take such action with respect to such
Default or Event of Default as shall reasonably be directed by the Required
Lenders, PROVIDED THAT, unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lenders.

         10.4     RIGHTS AS A LENDER.

         With respect to its Commitment and the Loans made by it, First Union
National Bank (and any successor acting as Agent) in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as the Agent, and the
term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include the Agent in its individual capacity. First Union National Bank (and any
successor acting as Agent) and its Affiliates may (without having to account
therefor to any Lender) accept deposits from, lend money to, make investments
in, provide services to, and generally engage in any kind of lending, trust, or
other business with any Credit Party or any of its Subsidiaries or Affiliates as
if it were not acting as Agent, and First Union National Bank (and any successor
acting as Agent) and its Affiliates may accept fees and other consideration from
any Credit Party or any of its Subsidiaries or Affiliates for services in
connection with this Credit Agreement or otherwise without having to account for
the same to the Lenders.

         10.5     INDEMNIFICATION.

         The Lenders agree to indemnify the Agent (to the extent not reimbursed
under Section 11.5 hereof, but without limiting the obligations of the Borrower
under such Section) ratably in accordance with their respective Commitments, for
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including attorneys' fees), or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Agent (including by any Lender) in any way relating to or
arising out of any



                                       96
<PAGE>

Credit Document or the transactions contemplated thereby or any action taken or
omitted by the Agent under any Credit Document; PROVIDED that no Lender shall be
liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified. Without
limitation of the foregoing, each Lender agrees to reimburse the Agent promptly
upon demand for its ratable share of any costs or expenses payable by the
Borrower under Section 11.5, to the extent that the Agent is not promptly
reimbursed for such costs and expenses by the Borrower. The agreements in this
Section 10.5 shall survive the repayment of the Loans, LOC Obligations and other
obligations under the Credit Documents and the termination of the Commitments
hereunder.

         10.6     NON-RELIANCE ON AGENT AND OTHER LENDERS.

         Each Lender agrees that it has, independently and without reliance on
the Agent or any other Lender, and based on such documents and information as it
has deemed appropriate, made its own credit analysis of the Credit Parties and
their Subsidiaries and decision to enter into this Credit Agreement and that it
will, independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own analysis and decisions in taking or not taking
action under the Credit Documents. Except for notices, reports, and other
documents and information expressly required to be furnished to the Lenders by
the Agent hereunder, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition, or business of any Credit Party or any of its Subsidiaries
or Affiliates that may come into the possession of the Agent or any of its
Affiliates.

         10.7     SUCCESSOR AGENT.

         The Agent may resign at any time by giving notice thereof to the
Lenders and the Borrower. Upon any such resignation, the Required Lenders shall
have the right to appoint a successor Agent. If no successor Agent shall have
been so appointed by the Required Lenders and shall have accepted such
appointment within thirty (30) days after the retiring Agent's giving of notice
of resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent which shall be a commercial bank organized under the laws of the
United States of America having combined capital and surplus of at least
$100,000,000. Upon the acceptance of any appointment as Agent hereunder by a
successor, such successor shall thereupon succeed to and become vested with all
the rights, powers, discretion, privileges, and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 10 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
Agent.

         If the Agent shall become aware that it has become a "foreign interest"
(as such term is defined in paragraph 1.231-1 of the Department of Defense
Industrial Security Regulation, D.O.D. 5220.22-R (December 1985)) at any time
during the term of this Agreement, the Agent shall resign as Agent under this
Agreement and



                                       97
<PAGE>


the other Credit Documents. If the Required Lenders shall become aware that the
Agent shall have become a "foreign interest" (as so defined), then the Required
Lenders shall remove the Agent as Agent under this Agreement and the other
Credit Documents. If the Agent shall become aware that any subagent, deed of
trust trustee or other Person acting in a fiduciary or representative capacity
under any of the Credit Documents shall become a "foreign interest" (as so
defined), then the Agent shall remove such Person from acting in such capacity.
Notwithstanding anything to the contrary contained therein, each Credit Document
shall be subject to the foregoing provisions of this Section 10.7. Any successor
Agent, or other Person appointed to act in a fiduciary or representative
capacity shall not be a "foreign interest" (as so defined).

         With respect to any notice delivered to the Agent to the effect that a
Default or an Event of Default exists, the Borrower shall promptly deliver a
copy thereof (by hand delivery or facsimile transmission) to the U.S. Department
of Defense, Defense Security Service, at 1340 Braddock Place, Alexandria,

         11.2     RIGHT OF SET-OFF; ADJUSTMENTS.

         Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates in connection with Hedging Agreements)
is hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Lender (or any of its Affiliates in connection with
Hedging Agreements) to or for the credit or the account of any Credit Party
against any and all of the obligations of such Person now or hereafter existing
under this Credit Agreement, under the Notes, under any other Credit Document or
otherwise, irrespective of whether such Lender shall have made any demand under
hereunder or thereunder and although such obligations may be unmatured. Each
Lender agrees promptly to notify any affected Credit Party after any such
set-off and application made by such Lender; PROVIDED, HOWEVER, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 11.2 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.

         11.3     BENEFIT OF AGREEMENT.

                  (a) This Credit Agreement shall be binding upon and inure to
         the benefit of and be enforceable by the respective successors and
         assigns of the parties hereto; PROVIDED that none of the Credit Parties
         may assign or transfer any of its interests and obligations without
         prior written consent of the Lenders; PROVIDED FURTHER that the rights
         of each Lender to transfer, assign or grant participations in its
         rights and/or obligations hereunder shall be limited as set forth in
         this Section 11.3.

                  (b) Each Lender may assign to one or more Eligible Assignees
         all or a portion of its rights and obligations under this Credit
         Agreement (including, without limitation, all or a portion of its
         Loans, its Notes, and its Commitment); PROVIDED, HOWEVER, that

                           (i) each such assignment shall be to an Eligible
                  Assignee;



                                       99
<PAGE>


                           (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's rights and
                  obligations under this Credit Agreement, any such partial
                  assignment shall be in an amount at least equal to $5,000,000
                  (or, if less, the remaining amount of the Commitment being
                  assigned by such Lender) or an integral multiple of $1,000,000
                  in excess thereof;

                           (iii) the parties to such assignment shall execute
                  and deliver to the Agent for its acceptance an Assignment and
                  Acceptance in the form of Exhibit 11.3(b) hereto, together
                  with any Note subject to such assignment and a processing fee
                  of $3,500.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance, the assignee thereunder shall be a party hereto and, to the
         extent of such assignment, have the obligations, rights, and benefits
         of a Lender hereunder and the assigning Lender shall, to the extent of
         such assignment, relinquish its rights and be released from its
         obligations under this Credit Agreement. Upon the consummation of any
         assignment pursuant to this Section 11.3(b), the assignor, the Agent
         and the Borrower shall make appropriate arrangements so that, if
         required, new Notes are issued to the assignor and the assignee. If the
         assignee is not incorporated under the laws of the United States of
         America or a state thereof, it shall deliver to the Borrower and the
         Agent certification as to exemption from deduction or withholding of
         Taxes in accordance with Section 3.11. No assignee shall be entitled to
         receive any greater payment or indemnification under Section 3.11 than
         the assigning Lender would have been entitled to receive with respect
         to the rights assigned unless such assignment shall have been made at a
         time when the circumstances giving rise to such greater payment did not
         exist.

                  (c) The Agent shall maintain at its address referred to in
         Section 11.1 a copy of each Assignment and Acceptance delivered to and
         accepted by it and a register for the recordation of the names and
         addresses of the Lenders and the Commitment of, and principal amount of
         the Loans owing to, each Lender from time to time (the "REGISTER"). The
         entries in the Register shall be conclusive and binding for all
         purposes, absent manifest error, and the Borrower, the Agent and the
         Lenders may treat each Person whose name is recorded in the Register as
         a Lender hereunder for all purposes of this Credit Agreement. The
         Register shall be available for inspection by the Borrower or any
         Lender at any reasonable time and from time to time upon reasonable
         prior notice.

                  (d) Upon its receipt of an Assignment and Acceptance executed
         by the parties thereto, together with any Note subject to such
         assignment and payment of the processing fee, the Agent shall, if such
         Assignment and Acceptance has been completed and is in substantially
         the form of Exhibit 11.3(b) hereto, (i) accept such Assignment and
         Acceptance, (ii) record the information contained therein in the
         Register and (iii) give prompt notice thereof to the parties thereto.

                  (e) Each Lender may sell participations to one or more Persons
         in all or a portion of its rights and obligations under this Credit
         Agreement (including all or a portion of its Commitment and its Loans);
         PROVIDED, HOWEVER, that (i) such Lender's



                                      100
<PAGE>


         obligations under this Credit Agreement shall remain unchanged, (ii)
         such Lender shall remain solely responsible to the other parties hereto
         for the performance of such obligations, (iii) the participant shall be
         entitled to the benefit of the yield protection provisions contained in
         Sections 3.7 through 3.12 (PROVIDED that the Borrower's liability in
         aggregate for both the Lender and its participant shall be limited to
         the amount it would owe the Lender granting the participation),
         inclusive, and the right of set-off contained in Section 11.2, and (iv)
         the Borrower shall continue to deal solely and directly with such
         Lender in connection with such Lender's rights and obligations under
         this Credit Agreement, and such Lender shall retain the sole right to
         enforce the obligations of the Borrower relating to its Loans and its
         Notes and to approve any amendment, modification, or waiver of any
         provision of this Credit Agreement (other than amendments,
         modifications, or waivers decreasing the amount of principal of or the
         rate at which interest is payable on such Loans or Notes, extending any
         scheduled principal payment date or date fixed for the payment of
         interest on such Loans or Notes, or extending its Commitment).

                  (f) Notwithstanding any other provision set forth in this
         Credit Agreement, any Lender may at any time assign and pledge all or
         any portion of its Loans and its Notes to any Federal Reserve Bank as
         collateral security pursuant to Regulation A and any Operating Circular
         issued by such Federal Reserve Bank. No such assignment shall release
         the assigning Lender from its obligations hereunder.

                  (g) Any Lender may furnish any information concerning the
         Borrower or any of its Subsidiaries in the possession of such Lender
         from time to time to assignees and participants (including prospective
         assignees and participants), subject, however, to the provisions of
         Section 11.16 hereof.

         11.4     NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Agent or any Lender and any of the
Credit Parties shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder or under any other
Credit Document preclude any other or further exercise thereof or the exercise
of any other right, power or privilege hereunder or thereunder. The rights and
remedies provided herein are cumulative and not exclusive of any rights or
remedies which the Agent or any Lender would otherwise have. No notice to or
demand on any Credit Party in any case shall entitle the Borrower or any other
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agent or the Lenders
to any other or further action in any circumstances without notice or demand.

         11.5     EXPENSES; INDEMNIFICATION.

         (a) The Borrower agrees to pay on demand all costs and expenses of the
Agent in connection with the syndication, preparation, execution, delivery,
administration, modification, and amendment of this Credit Agreement, the other
Credit Documents, and the other documents



                                      101
<PAGE>


to be delivered hereunder, including, without limitation, the reasonable fees
and expenses of counsel for the Agent (including the reasonable cost of internal
counsel) with respect thereto and with respect to advising the Agent as to its
rights and responsibilities under the Credit Documents. The Borrower further
agrees to pay on demand all costs and expenses of the Agent and the Lenders, if
any (including, without limitation, reasonable attorneys' fees and expenses and
the reasonable cost of internal counsel), in connection with the enforcement
(whether through negotiations, legal proceedings, or otherwise) of the Credit
Documents and the other documents to be delivered hereunder.

         (b) The Borrower agrees to indemnify and hold harmless the Agent and
each Lender and each of their Affiliates and their respective officers,
directors, employees, agents, and advisors (each, an "INDEMNIFIED PARTY") from
and against any and all claims, damages, losses, liabilities, costs, and
expenses (including, without limitation, reasonable attorneys' fees) that may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of (including, without
limitation, in connection with any investigation, litigation, or proceeding or
preparation of defense in connection therewith) the Credit Documents, any of the
transactions contemplated herein or the actual or proposed use of the proceeds
of the Loans, except to the extent such claim, damage, loss, liability, cost, or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct. In the case of an investigation, litigation or other
proceeding to which the indemnity in this Section 11.5 applies, such indemnity
shall be effective whether or not such investigation, litigation or proceeding
is brought by the Borrower, its directors, shareholders or creditors or an
Indemnified Party or any other Person or any Indemnified Party is otherwise a
party thereto and whether or not the transactions contemplated hereby are
consummated. The Borrower agrees not to assert any claim against the Agent, any
Lender, any of their Affiliates, or any of their respective directors, officers,
employees, attorneys, agents, and advisers, on any theory of liability, for
special, indirect, consequential, or punitive damages arising out of or
otherwise relating to the Credit Documents, any of the transactions contemplated
herein or the actual or proposed use of the proceeds of the Loans.

         (c) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 11.5 shall survive the repayment of the Loans, LOC Obligations and
other obligations under the Credit Documents and the termination of the
Commitments hereunder.

         11.6     AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, PROVIDED, HOWEVER, that:

                  (a)      without the consent of each Lender affected thereby,



                                      102

                        (i) extend the final maturity of any Loan or the time of

                  extend or waive any Principal Amortization Payment of any
                  Loan, or any portion thereof,

                       (ii) reduce the rate or extend the time of payment of
                  interest (other than as a result of waiving the applicability
                  of any post-default increase in interest rates) thereon or
                  Fees hereunder,

                      (iii) reduce or waive the principal amount of any Loan or
                  of any reimbursement obligation, or any portion thereof,
                  arising from drawings under Letters of Credit,

                       (iv) increase the Commitment of a Lender over the amount
                  thereof in effect (it being understood and agreed that a
                  waiver of any Default or Event of Default or mandatory
                  reduction in the Commitments shall not constitute a change in
                  the terms of any Commitment of any Lender),

                        (v) except as the result of or in connection with an

                  of the other Credit Parties from its or their obligations
                  under the Credit Documents,

                           (vii) except amend, modify or waive any provision of
                  this Section 11.6 or Section 3.6, 3.7, 3.8, 3.9, 3.10, 3.11,
                  3.12, 3.13, 3.14, 9.1(a), 11.2, 11.3, 11.5 or 11.9,

                           (viii) reduce any percentage specified in, or
                  otherwise modify, the definition of Required Lenders, or

                           (ix) consent to the assignment or transfer by the
                  Borrower or all or substantially all of the other Credit
                  Parties of any of its or their rights and obligations under
                  (or in respect of) the Credit Documents except as permitted
                  thereby;

                  (b) without the consent of Lenders holding in the aggregate
         more than 50% of the outstanding Tranche A Term Loans and more than 50%
         of the outstanding Tranche B Term Loans, extend the time for or the
         amount or the manner of application of proceeds of any mandatory
         prepayment required by Section 3.3(b)(ii), (iii), (iv) or (v) hereof;

                  (c) without the consent of the Agent, no provision of Section
         10 may be amended;

<PAGE>

                  (e) without the consent of the Swingline Lender, no provision
         of Section 2.3 may be amended.

         Notwithstanding the fact that the consent of all the Lenders is
         required in certain circumstances as set forth above, (x) each Lender
         is entitled to vote as such Lender sees fit on any bankruptcy
         reorganization plan that affects the Loans, and each Lender
         acknowledges that the provisions of Section 1126(c) of the Bankruptcy
         Code supersedes the unanimous consent provisions set forth herein and
         (y) the Required Lenders may consent to allow a Credit Party to use
         cash collateral in the context of a bankruptcy or insolvency
         proceeding.

         11.7     COUNTERPARTS.

         This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. It shall not be necessary in
making proof of this Credit Agreement to produce or account for more than one
such counterpart for each of the parties hereto. Delivery by facsimile by any of
the parties hereto of an executed counterpart of this Credit Agreement shall be
as effective as an original executed counterpart hereof and shall be deemed a
representation that an original executed counterpart hereof will be delivered.

         11.8     HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

         11.9     SURVIVAL.

         All indemnities set forth herein, including, without limitation, in
Section 2.2(i), 3.11, 3.12, 10.5 or 11.5 shall survive the execution and

Letters of Credit, the repayment of the Loans, LOC Obligations and other
obligations under the Credit Documents and the termination of the Commitments
hereunder, and all representations and warranties made by the Credit Parties

         11.10    GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE.

                  (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND
         THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER
         SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH
         THE LAWS OF THE STATE OF NORTH CAROLINA. Any legal action or proceeding
         with respect to this Credit Agreement or any other Credit Document may
         be brought in the courts of the State of North Carolina in Mecklenburg
         County, or of the United States for the Western District of North
         Carolina, and, by execution and delivery of this Credit Agreement, each
         of the Credit Parties



                                      104
<PAGE>

         hereby irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the nonexclusive jurisdiction of such
         courts. Each of the Credit Parties further irrevocably consents to the
         service of process out of any of the aforementioned courts in any such
         action or proceeding by the mailing of copies thereof by registered or
         certified mail, postage prepaid, to it at the address set out for
         notices pursuant to Section 11.1, such service to become effective
         three (3) Business Days after such mailing. Nothing herein shall affect
         the right of the Agent or any Lender to serve process in any other
         manner permitted by law or to commence legal proceedings or to
         otherwise proceed against any Credit Party in any other jurisdiction.

                  (b) Each of the Credit Parties hereby irrevocably waives any
         objection which it may now or hereafter have to the laying of venue of
         any of the aforesaid actions or proceedings arising out of or in
         connection with this Credit Agreement or any other Credit Document
         brought in the courts referred to in subsection (a) above and hereby
         further irrevocably waives and agrees not to plead or claim in any such
         court that any such action or proceeding brought in any such court has
         been brought in an inconvenient forum.

                  (c) TO THE EXTENT PERMITTED BY LAW, EACH OF THE AGENT, THE
         LENDERS, THE BORROWER AND THE CREDIT PARTIES HEREBY IRREVOCABLY WAIVES
         ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
         ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER
         CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         11.11    SEVERABILITY.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         11.12    ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede
all prior agreements and understandings, oral or written, if any, including any
commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.

         11.13    BINDING EFFECT; TERMINATION.

                  (a) This Credit Agreement shall become effective at such time
         on or after the Closing Date when it shall have been executed by the
         Borrower, the Guarantors and the Agent, and the Agent shall have
         received copies hereof (telefaxed or otherwise) which, when taken
         together, bear the signatures of each Lender, and thereafter this
         Credit Agreement shall be binding upon and inure to the benefit of the
         Borrower, the Guarantors, the Agent and each Lender and their
         respective successors and assigns.



                                      105
<PAGE>

                  (b) The term of this Credit Agreement shall be until no Loans,
         LOC Obligations or any other amounts payable hereunder or under any of
         the other Credit Documents shall remain outstanding, no Letters of
         Credit shall be outstanding, all of the Credit Party Obligations have
         been irrevocably satisfied in full and all of the Commitments hereunder
         shall have expired or been terminated.

         11.14    SOURCE OF FUNDS.

         Each of the Lenders hereby represents and warrants to the Borrower that
at least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

                  (a) no part of such funds constitutes assets allocated to any
         separate account maintained by such Lender in which any employee
         benefit plan (or its related trust) has any interest;

                  (b) to the extent that any part of such funds constitutes
         assets allocated to any separate account maintained by such Lender,
         such Lender has disclosed to the Borrower the name of each employee
         benefit plan whose assets in such account exceed 10% of the total
         assets of such account as of the date of such purchase (and, for
         purposes of this subsection (b), all employee benefit plans maintained
         by the same employer or employee organization are deemed to be a single
         plan);

                  (c) to the extent that any part of such funds constitutes
         assets of an insurance company's general account, such insurance
         company has complied with all of the requirements of the regulations
         issued under Section 401(c)(1)(A) of ERISA; or

                  (d) such funds constitute assets of one or more specific
         benefit plans which such Lender has identified in writing to the
         Borrower.

As used in this Section 11.14, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

         11.15    CONFLICT.

         To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.

         11.16    CONFIDENTIALITY.

         The Agent and each Lender will hold all non-public information,
obtained pursuant to the requirements of this Credit Agreement (and including
the financial information), in accordance with its customary procedure for
handling confidential information of such nature and in accordance with safe and
sound commercial lending practices, but may, in any event, make



                                      106
<PAGE>

disclosure (i) on a confidential basis to its officers, directors, employees,
agents, representatives and advisers (including regular and special accountants
and legal counsel), (ii) to any transferee or participant, or prospective
transferee or participant, in connection with the contemplated transfer of the
Loans and Commitments hereunder or participations thereof; provided such
transferees or participants, or prospective transferees or participants, shall
consent in writing to be bound by the terms of this Section 11.16, (iii) as
required or requested by any governmental agency or representative thereof in
the ordinary course of the Lender's regulatory compliance or the National
Association of Insurance Commissioners to the extent so required, or (iv)
pursuant to legal process; PROVIDED that (A) such party shall, to the extent
reasonably possible, give the Borrower five days prior written notice thereof;
it being understood, however, that the failure to give any such notice shall not
give rise to any action or claim on account of any such failure and (B) neither
the Agent, nor any of the Lenders shall have any obligation under this Section
11.16 to the extent that any such information becomes available on a
non-confidential basis from a source other than the Borrower or its
Subsidiaries, or that any such information becomes publicly available other than
by breach of this Section 11.16.

         11.17    ARBITRATION; CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

         (a) Upon demand of any party hereto, whether made before or after
institution of any judicial action, any dispute, claim or controversy arising
out of or connected herewith or with the Credit Documents ("Disputes") shall be
resolved by binding arbitration as provided herein. Disputes may include,
without limitation, tort claims, counterclaims, claims brought as class actions
and claims arising herefrom or from Credit Documents executed in the future.
Arbitration shall be conducted under the Commercial Financial Disputes
Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association and Title 9 of the U.S. Code. All arbitration hearings shall be
conducted in Charlotte, Mecklenburg County, North Carolina, or such other place
as agreed to in writing by the parties. A judgment upon the award may be entered
in any court having jurisdiction, and all decisions shall be in writing. The
panel from which all arbitrators are selected shall be comprised of licensed
attorneys having at least ten years' experience representing parties in secured
lending transactions. Notwithstanding the foregoing, this arbitration provision
does not apply to disputes under or related to interest protection agreements.

         (b) Notwithstanding the preceding binding arbitration provision, the
Agent, on behalf of the Lenders, preserves certain remedies that may be
exercised during a Dispute. The Agent, on behalf of the Lenders, shall have the
right to proceed in any court of proper jurisdiction or by self help to exercise
or prosecute the following remedies, as applicable: (i) all rights to foreclose
against any real or personal property or other security by exercising a power of
sale granted in the Credit Documents or under applicable law, (ii) all rights of
self help including peaceful occupation of real property and collection of
rents, set-off and peaceful possession of personal property, (iii) obtaining
provisional or ancillary remedies including injunctive relief, sequestration,
garnishment, attachment and appointment of receiver, and (iv) other remedies.
Preservation of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a Dispute.



                                      107
<PAGE>

         (c) By execution and delivery of this Credit Agreement, each of the
parties hereto accepts, for itself and in connection with its properties,
generally and unconditionally, the non-exclusive jurisdiction relating to any
arbitration proceedings conducted under the Arbitration Rules in Charlotte,
Mecklenburg County, North Carolina and irrevocably agrees to be bound by any
final judgment rendered thereby in connection with this Credit Agreement from
which no appeal has been taken or is available. Each of the parties hereto
irrevocably agrees that all process in any such arbitration proceedings or
otherwise may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to it at its
address set forth in Section 11.1 or at such other address of which such party
shall have been notified pursuant thereto, such service being hereby
acknowledged by each party hereto to be effective and binding service in every
respect. Each party hereto irrevocably waives any objection, including, without
limitation, any objection to the laying of venue or based on the grounds of
forum non conveniens which it may now or hereafter have to the bringing of any
such action or proceeding in any such jurisdiction. Nothing herein shall affect
the right to serve process in any other manner permitted by law or shall limit
the right of any party to bring proceedings against the Borrower or any party

the Company have approved the acquisition of the Company by Parent on the terms
and subject to the conditions set forth in this Agreement;

                  WHEREAS, in furtherance of such acquisition, Parent proposes

COMMON STOCK"), at a price per share of Company Common Stock of $22.00, net to

forth in this Agreement;

                  WHEREAS the respective Boards of Directors of Parent, Sub and

                  WHEREAS, simultaneously with the execution and delivery of

and also to prescribe various conditions to the Offer and the Merger.

                  NOW, THEREFORE, the parties hereto agree as follows:


                                    ARTICLE I

                            The Offer and the Merger

                  SECTION 1.01. THE OFFER. (a) Provided that this Agreement
shall not have been terminated in accordance with Article VIII hereof and
subject to the conditions set forth in Exhibit A hereto (the "TENDER OFFER
CONDITIONS"), as promptly as practicable but in no event later than five
business days after the date of the public announcement by Parent and the
Company of this Agreement (the "ANNOUNCEMENT DATE"), Sub shall, and Parent shall
cause Sub to, commence the Offer within the meaning of Rule

<PAGE>
                                                                              3

14d-2 under the
Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), for all the outstanding shares of Company Common Stock at the Offer
Price. The obligation of Sub to, and of Parent to cause Sub to, commence the
Offer and accept for payment, and pay for, any shares of Company Common Stock
tendered pursuant to the Offer are subject only to the provisions of Article
VIII and the Tender Offer Conditions (any of which may be waived by Sub in its
sole discretion, except as otherwise provided herein). Sub expressly reserves
the right to modify the terms of the Offer, except that, without the prior
written consent of the Company, Sub shall not (i) reduce the number of shares of
Company Common Stock subject to the Offer, (ii) reduce the price per share of
Company Common Stock to be paid pursuant to the Offer, (iii) modify or add to
the Tender Offer Conditions, (iv) waive the Minimum Tender Condition (except
that Sub may waive the Minimum Tender Condition if the failure of such condition
to be satisfied results from the failure of the Principal Shareholders to
validly tender any Subject Shares, as defined in the Shareholder Agreement,
prior to the expiration of the Offer, or from the withdrawal of any Subject
Shares prior to the expiration of the Offer) or amend any other term of the
Offer in any manner materially adverse to the holders of Company Common Stock or
(v) except as provided below, extend the Offer if all the Tender Offer
Conditions have been satisfied. Subject to the terms and conditions hereof, the
Offer shall remain open until midnight, New York City time, on the date that is
20 business days after the Offer is commenced (within the meaning of Rule 14d-2
of the Exchange Act); PROVIDED, HOWEVER, that without the prior written consent
of the Company, Sub may (A) if at the scheduled initial or any extended
expiration date (whether extended pursuant to this clause (A) or otherwise) of
the Offer any of the Tender Offer Conditions shall not have been satisfied or
waived, extend the Offer for up to five business days from such scheduled
initial or extended expiration date, (B) extend the Offer for any period
required by any rule, regulation, interpretation or position of the Securities
and Exchange Commission (the "SEC") or the staff thereof applicable to the
Offer, (C) if at the scheduled initial or any extended expiration date of the
Offer all the Tender Offer Conditions are satisfied and more than 70% but less
than 90% of the Fully Diluted Shares (as defined in Exhibit A) have been validly
tendered and not withdrawn in the Offer, extend the Offer up to a maximum of 10
additional business days in the aggregate beyond the latest expiration date that
would otherwise be permitted under clause (A) or (B) of this sentence and (D)
extend the Offer for any reason for a period of not more than three business
days beyond the latest expiration date that would otherwise be permitted under
clause (A), (B) or (C) of this sentence. On the terms and subject to the
conditions of the Offer and this Agreement, Parent shall cause Sub to, and Sub
shall, accept for payment and pay for all shares of Company Common Stock validly
tendered and not withdrawn pursuant to the Offer that Sub becomes obligated to
purchase pursuant to the Offer as soon as practicable after the expiration of
the Offer.

(b) On the date of commencement of the Offer, Parent and Sub
shall file with the SEC a Tender Offer Statement on Schedule 14D-1 with respect
to the Offer, which shall contain an offer to purchase and a related letter of
transmittal and summary advertisement (such Schedule 14D-1 and the documents
included therein pursuant to which the Offer will be made, together with any
supplements or amendments thereto, the "OFFER DOCUMENTS"). Each of Parent, Sub
and the Company shall promptly correct any information provided by it for use in
the Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect, and each of Parent and Sub shall
take all steps necessary to amend or supplement the Offer Documents and to cause
the Offer Documents as so amended or supplemented to be filed with the SEC and
to be disseminated to the Company's shareholders, in each case as and to the
extent required by applicable Federal securities laws. Parent and Sub shall
provide the

                                                                         4

Company and its counsel in writing with any comments Parent, Sub or their
counsel may receive from the SEC or its staff with respect to the Offer
Documents promptly after the receipt of such comments.

                  (c) Parent shall provide or cause to be provided to Sub on a
timely basis the funds sufficient to accept for payment, and pay for, any and
all shares of Company Common Stock that Sub becomes obligated to accept for
payment, and pay for, pursuant to the Offer. Parent and Sub shall comply with
the obligations respecting prompt payment pursuant to Rule 14e-1(c) under the
Exchange Act.

                  SECTION 1.02. COMPANY ACTIONS. (a) The Company hereby approves
of and consents to the Offer, the Merger and the other transactions contemplated
by the Transaction Agreements (collectively, the "TRANSACTIONS"), subject, in
the case of the Merger, to receipt of the Company Shareholder Approval and
subject to withdrawal of such approval and consent if permitted by Section
5.02(b).

                  (b) On the date the Offer Documents are filed with the SEC,
the Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended or
supplemented from time to time, the "SCHEDULE 14D-9") containing the
recommendations described in Section 3.04(b) and shall mail the Schedule 14D-9
to the holders of Company Common Stock. Each of the Company, Parent and Sub
shall promptly correct any information provided by it for use in the Schedule
14D-9 if and to the extent that such information shall have become false or
misleading in any material respect, and the Company shall take all steps
necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule
14D-9 as so amended or supplemented to be filed with the SEC and disseminated to
the Company's shareholders, in each case as and to the extent required by
applicable Federal securities laws. The Company shall provide Parent and its
counsel in writing with any comments the Company or its counsel may receive from
the SEC or its staff with respect to the Schedule 14D-9 promptly after the
receipt of such comments.

                  (c) In connection with the Offer, the Company shall cause its
transfer agent to furnish Sub promptly with mailing labels containing the names
and addresses of the record holders of Company Common Stock as of a recent date
and of those persons becoming record holders

<PAGE>
                                                                               5


subsequent to such date, together with copies of all lists of shareholders,
security position listings and computer files and all other information in the
Company's possession or control regarding the beneficial owners of Company
Common Stock, and shall furnish to Sub such information and assistance
(including updated lists of shareholders, security position listings and
computer files) as Parent may reasonably request in communicating the Offer to
the Company's shareholders. Subject to the requirements of applicable Law (as
defined in Section 3.05(a)), and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Transactions, Parent and Sub shall hold in confidence the information
contained in any such labels, listings and files, shall use such information
only in connection with the Offer and the Merger and, if this Agreement shall be
terminated, shall deliver to the Company all copies of such information then in
their possession.

                  SECTION 1.03. THE MERGER. On the terms and subject to the
conditions set forth in this Agreement, and in accordance with the Texas
Business Corporation Act (the "TBCA"), Sub shall be merged with and into the
Company at the Effective Time (as defined in Section 1.05). At the Effective
Time, the separate corporate existence of Sub shall cease and the Company shall
continue as the surviving corporation (the "SURVIVING CORPORATION").

                  SECTION 1.04. CLOSING. The closing (the "CLOSING") of the
Merger shall take place at the offices of Cravath, Swaine & Moore, 825 Eighth
Avenue, New York, New York 10019 at 10:00 a.m. on the second business day
following the satisfaction (or, to the extent permitted by Law, waiver by all
parties) of the conditions set forth in Section 7.01, or at such other place,
time and date as shall be agreed in writing between Parent and the Company. The
date on which the Closing occurs is referred to in this Agreement as the
"CLOSING DATE".

                  SECTION 1.05. EFFECTIVE TIME. Prior to the Closing, the
Company shall prepare, and on the Closing Date the Company shall file with the
Secretary of State of the State of Texas, articles of merger (the "ARTICLES OF
MERGER") executed in accordance with the relevant provisions of the TBCA and
shall make all other filings or recordings required under the TBCA. The Merger
shall become effective upon issuance of the certificate of merger by the
Secretary of State of the State of Texas, or at such later time as Parent and
the Company shall

                                                                               6

                  SECTION 1.06. EFFECTS.  The Merger shall have the
effects set forth in Article 5.06 of the TBCA.

                  SECTION 1.07. ARTICLES OF INCORPORATION AND BYLAWS. (a) The
Articles of Incorporation of the Company, as in effect immediately prior to the
Effective Time, shall be amended at the Effective Time so that Article Four,
Section 1 of such Articles of Incorporation reads in its entirety as follows:
"The total number of shares of all classes of stock which the Corporation shall
have authority to issue is 1,000 shares of Common Stock, par value $0.01 per
share." and, as so amended, such Articles of Incorporation shall be the Articles
of Incorporation of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable Law.

                  (b) The By-laws of Sub as in effect immediately prior to the
Effective Time shall be the By-laws of the Surviving Corporation until
thereafter changed or amended as provided therein or by applicable Law.

                  SECTION 1.08. DIRECTORS. The directors of Sub immediately
prior to the Effective Time shall be the directors of the Surviving Corporation,
until the earlier of their resignation or removal or until their respective

                  SECTION 1.09. OFFICERS. The officers of the Company
immediately prior to the Effective Time shall be the officers of the Surviving

                       EFFECT ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

                  SECTION 2.01. EFFECT ON CAPITAL STOCK. At the Effective Time,
by virtue of the Merger and without any

                                                                               7


action on the part of the holder of any shares of Company Common Stock or any
shares of capital stock of Sub:

                  (a) CAPITAL STOCK OF SUB. Each issued and outstanding share of
         capital stock of Sub shall be converted into and become one fully paid
         and non assessable share of common stock, par value $0.01 per share, of
         the Surviving Corporation.

                  (b) CANCELATION OF TREASURY STOCK AND PARENT- OWNED STOCK.
         Each share of Company Common Stock that is owned by the Company, Parent
         or Sub shall no longer be outstanding and shall automatically be
         canceled and retired and shall cease to exist, and no Parent Common
         Stock or other consideration shall be delivered or deliverable in
         exchange therefor. Each share of Company Common Stock that is owned by
         any subsidiary of the Company or Parent (other than Sub) shall
         automatically be converted into one fully paid and nonassessable share
         of common stock, par value $0.01 per share, of the Surviving
         Corporation.

                  (c) CONVERSION OF COMPANY COMMON STOCK. (i) Subject to
         Sections 2.01(b) and 2.01(d), each issued share of Company Common Stock
         shall be converted into the right to receive an amount in cash equal to
         the Offer Price, without interest (the "PER SHARE MERGER
         CONSIDERATION").

                  (ii) The cash payable upon the conversion of shares of Company
         Common Stock pursuant to this Section 2.01(c) is referred to
         collectively as the "MERGER CONSIDERATION". As of the Effective Time,
         all such shares of Company Common Stock shall no longer be outstanding
         and shall automatically be canceled and retired and shall cease to
         exist, and each holder of a certificate formerly representing any such
         shares of Company Common Stock shall cease to have any rights with
         respect thereto, except the right to receive cash in an amount equal to
         the Per Share Merger Consideration multiplied by the number of shares
         of Company Common Stock formerly represented by such certificate,
         without interest, upon surrender of such certificate in accordance with
         Section 2.02, subject to Section 2.01(d) hereof.

                  (d) DISSENT RIGHTS. Notwithstanding anything in this Agreement
         to the contrary, shares (the "DISSENT SHARES") of Company Common Stock
         that are outstanding immediately prior to the Effective Time


<PAGE>

                                                                               8


         and that are held by any person who is entitled to dissent from and
         properly dissents from this Agreement pursuant to, and who complies in
         all respects with, Articles 5.11, 5.12, 5.13 and 5.16 of the TBCA, in
         each case to the extent applicable (the "DISSENT STATUTES"), shall not
         be converted into Merger Consideration as provided in Section 2.01(c),
         but rather the holders of Dissent Shares shall be entitled to payment
         of the fair value of such Dissent Shares in accordance with the Dissent
         Statutes; PROVIDED, HOWEVER, that if any such holder shall fail to
         perfect or otherwise shall waive, withdraw or lose the right to receive
         payment of fair value under the Dissent Statutes, then the right of
         such holder to be paid the fair value of such holder's Dissent Shares
         shall cease and such Dissent Shares shall be deemed to have been
         converted as of the Effective Time into, and to have become
         exchangeable solely for the right to receive, Merger Consideration
         as provided in Section 2.01(c). The Company shall serve prompt notice
         to Parent of any objections or demands for payment of fair value of
         Company Common Stock pursuant to the Dissent Statutes received by the
         Company, and Parent shall have the right to participate in and direct
         all negotiations and proceedings with respect to such objections or
         demands. Prior to the Effective Time, the Company shall not, without
         the prior written consent of Parent, make any payment with respect to,
         or settle or offer to settle, any such objections or demands, or agree
         to do any of the foregoing.

                  SECTION 2.02. EXCHANGE OF CERTIFICATES. (a) PAYING AGENT.
Prior to the Effective Time, Parent shall select a bank or trust company
reasonably acceptable to the Company to act as paying agent (the "PAYING AGENT")
for the payment of the Merger Consideration upon surrender of certificates
representing Company Common Stock. At the Effective Time, Parent shall provide
to the Paying Agent the aggregate cash necessary to pay for the shares of
Company Common Stock converted into the right to receive cash pursuant to
Section 2.01(c) (such cash being hereinafter referred to as the "EXCHANGE
FUND").

                  (b) EXCHANGE PROCEDURE. As soon as reasonably practicable
after the Effective Time, Parent shall cause the Paying Agent to mail to each
holder of record of a certificate or certificates (the "CERTIFICATES") that
immediately prior to the Effective Time represented outstanding shares of
Company Common Stock whose shares


<PAGE>

                                                                               9


were converted into the right to receive Merger Consideration pursuant to
Section 2.01, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Paying Agent and shall be in such
form and have such other provisions, not inconsistent with this Agreement, as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for Merger Consideration. Upon
surrender of a Certificate for cancelation to the Paying Agent or to such other
agent or agents as may be appointed by Parent, together with such letter of
transmittal, duly executed, and such other documents, not inconsistent with this
Agreement, as may reasonably be required by Parent, Parent shall cause the
Paying Agent to pay the holder of such Certificates in exchange therefor cash in
an amount equal to the Per Share Merger Consideration multiplied by the number
of shares of Company Common Stock formerly represented by such Certificate
(other than Certificates representing Dissent Shares, Certificates representing
shares of Company Common Stock held by Parent or Sub or in the treasury of the
Company and Certificates representing shares of Company Common Stock held by any
subsidiary of the Company or Parent (other than Sub)), without interest, and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of Company Common Stock that is not registered in the
transfer records of the Company, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of such Certificate or establish to the satisfaction of Parent that such
tax has been paid or is not applicable. Until surrendered as contemplated by
this Section 2.02, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
amount of cash, without interest, into which the shares of Company Common Stock
theretofore represented by such Certificate have been converted pursuant to
Section 2.01. No interest shall be paid or shall accrue on the cash payable upon
surrender of any Certificate.

                  (c) NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. The
Merger Consideration paid in accordance with the terms of this Article II upon
conversion of any shares of Company Common Stock shall be


<PAGE>

                                                                              10


deemed to have been paid in full satisfaction of all rights pertaining to such
shares of Company Common Stock. After the Effective Time there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of shares of Company Common Stock that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, any certificates
formerly representing shares of Company Common Stock are presented to the
Surviving Corporation or the Paying Agent for any reason, they shall be canceled
and exchanged as provided in this Article II.

                  (d) LOST CERTIFICATES. In the event any Certificate shall have
been lost, stolen or destroyed, the Paying Agent shall be required to pay the
Per Share Merger Consideration for each share of Company Common Stock formerly
represented by such lost, stolen or destroyed certificate; PROVIDED, HOWEVER,
Sub may require the owner of such lost, stolen or destroyed certificate to
execute and deliver to the Paying Agent a form of affidavit claiming such
Certificate to be lost, stolen or destroyed in form and substance reasonably
satisfactory to Sub and the posting by such owner of a bond in such amount as
Sub may determine is reasonably necessary as indemnity against any claim that
may be made against Sub, Parent, the Company, the Surviving Corporation or the
Paying Agent in connection with the Certificate alleged to have been lost,
stolen or destroyed.

                  (e) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange
Fund that remains undistributed to the holders of Company Common Stock for six
months after the Effective Time shall be delivered to Parent, upon demand, and
any holder of Company Common Stock who has not theretofore complied with this
Article II shall thereafter look only to Parent for payment of its claim for
Merger Consideration.

                  (f) NO LIABILITY. None of Parent, Sub, the Company or the
Paying Agent shall be liable to any person in respect of any cash from the
Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar Law. If any Certificate has not been
surrendered prior to five years after the Effective Time (or immediately prior
to such earlier date on which Merger Consideration in respect of such
Certificate would otherwise escheat to or become the


<PAGE>
                                                                           11

property of any Governmental Entity (as defined in Section 3.05(b)), any such
shares, cash, dividends or distributions in respect of such Certificate shall,
to the extent permitted by applicable Law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto.

                  (g) INVESTMENT OF EXCHANGE FUND. The Paying Agent shall invest
any cash included in the Exchange Fund, as directed by Parent, on a daily basis.
Any interest and other income resulting from such investments shall be paid to
Parent.

                  (h) WITHHOLDING RIGHTS. Parent or the Surviving Corporation
shall be entitled to deduct and withhold from the consideration otherwise
payable to any holder of Company Common Stock pursuant to this Agreement such
amounts as may be required to be deducted and withheld with respect to the
making of such payment under the Code (as defined in Section 3.11(b)), or under
any applicable provision of state, local or foreign tax Law.


                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company represents and warrants to Parent and Sub as
follows:

                  SECTION 3.01. ORGANIZATION, STANDING AND POWER. The Company
and each of its subsidiaries (the "COMPANY SUBSIDIARIES") are duly organized,
validly existing and in good standing under the laws of the jurisdiction in
which they are organized and have all requisite corporate power and authority
and possess all governmental franchises, licenses, permits, authorizations and
approvals necessary to enable them to own, lease or otherwise hold their
properties and assets and to conduct their businesses as presently conducted,
other than such franchises, licenses, permits, authorizations and approvals the
lack of which, individually and in the aggregate, has not had and would not
reasonably be expected to have a Company Material Adverse Effect (as defined
below). The Company and each Company Subsidiary are duly qualified to do
business in each jurisdiction where the nature of their businesses or their
ownership or leasing of their properties make such qualification necessary,
except for failures to be so qualified which, individually and in the aggregate,
have not had and would not reasonably be expected to have a Company Material
Adverse Effect. The term "COMPANY MATERIAL ADVERSE EFFECT," as used in this
Agreement, means a material adverse effect on the business, assets, condition

(financial or otherwise) or results of operations of the Company and the Company
Subsidiaries, taken as a whole, on the ability of the Company to perform its
obligations under the Transaction Agreements or on the ability of the Company to
consummate the Offer, the Merger and the other Transactions. The Company has
made available to Parent true and complete copies of the articles of
incorporation of the Company, as amended to the date of this Agreement (as so
amended, the "COMPANY CHARTER"), and the By-laws of the Company, as amended to
the date of this Agreement (as so amended, the "COMPANY BY-LAWS"), and the
comparable charter and organizational documents of each Company Subsidiary, in
each case as amended through the date of this Agreement.

                  SECTION 3.02. COMPANY SUBSIDIARIES; EQUITY INTERESTS. (a) The
letter, dated as of the date of this Agreement, from the Company to Parent and
Sub (the "COMPANY DISCLOSURE LETTER") lists each Company Subsidiary and its
jurisdiction of organization. All the outstanding shares of capital stock of
each Company Subsidiary have been validly issued and are fully paid and
nonassessable and, except as set forth in the Company Disclosure Letter, are
owned by the Company, by another Company Subsidiary or by the Company and
another Company Subsidiary, free and clear of all pledges, liens, charges,
mortgages, encumbrances and security interests of any kind or nature whatsoever
(collectively, "LIENS").

                  (b) Except for its interests in the Company Subsidiaries and
except for the ownership interests set forth in the Company Disclosure Letter,
the Company does not own, directly or indirectly, any capital stock, membership
interest, partnership interest, joint venture interest or other equity interest
in any person.

                  SECTION 3.03. CAPITAL STRUCTURE. (a) The authorized capital
stock of the Company consists of 20,000,000 shares of Company Common Stock. At
the close of business on November 11, 1999, (i) 5,116,314 shares of Company
Common Stock were issued and outstanding, (ii) 119,437 shares of Company Common

Company Stock Options under the Company's 1995 Stock Compensation Plan, (vi)
32,000 shares of Company Common Stock were subject to outstanding Company Stock
Options under the Company's Non-Employee Directors Stock Option Plan and (vii)
401,800 additional shares of Company Common Stock were reserved for issuance
pursuant to the Company Stock Plans (as defined in Section 6.04(e)). Except as
set forth above, at the close of business on the date of this Agreement, no
shares of capital stock or other voting securities of the Company were issued,
reserved for issuance or outstanding. There are no outstanding Company SARs (as
defined in Section 6.04(e)) that were not granted in tandem with a related
Company Stock Option. All outstanding shares of Company capital stock are, and
all such shares that may be issued prior to the Effective Time will be when
issued, duly authorized, validly issued, fully paid and nonassessable and not
subject to or issued in violation of any purchase option, call option, right of
first refusal, preemptive right, subscription right or any similar right under
any provision of the TBCA, the Company Charter, the Company By-laws or any
contract, lease, license, indenture, note, bond, agreement, permit, concession,
franchise or other instrument (a "CONTRACT") to which the Company is a party or
otherwise bound. There are not any bonds, debentures, notes or other
indebtedness of the Company having the right to vote (or convertible into, or
exchangeable for, securities having the right to vote) on any matters on which
holders of Company Common Stock may vote ("VOTING COMPANY DEBT"). Except as set
forth above, as of the date of this Agreement, there are not any options,
warrants, rights, convertible or exchangeable securities, "phantom" stock
rights, stock appreciation rights, stock-based performance units, commitments,
Contracts, arrangements or undertakings of any kind to which the Company or any
Company Subsidiary is a party or by which any of them is bound (i) obligating
the Company or any Company Subsidiary to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock or other equity
interests in, or any security convertible or exercisable for or exchangeable
into any capital stock of or other equity interest in, the Company or of any
Company Subsidiary or any Voting Company Debt, (ii) obligating the Company or
any Company Subsidiary to issue, grant, extend or enter into any such option,
warrant, right, security, unit, commitment, Contract, arrangement or undertaking
or (iii) that give any person the right to receive any economic benefit or right
similar to or derived from the economic benefits and rights occurring to holders
of Company capital stock. As of the date of this Agreement, there are not any

                                                                              14


outstanding contractual obligations of the Company or any Company Subsidiary to
repurchase, redeem or otherwise acquire any shares of capital stock of the
Company or any Company Subsidiary. Except as set forth in the Company Disclosure
Letter or the Filed Company SEC Documents (as defined in Section 3.08), no
person is entitled to registration rights with respect to any shares of Company
Common Stock.

                  (b) The Company Board or a committee administering the Company
Stock Plans has the power and authority to cause (x) the Company Stock Plans to
terminate as of the Effective Time and (y) the provisions in any other Company
Benefit Plan providing for the issuance, transfer or grant of any capital stock
of the Company or any interest in respect of any capital stock of the Company to
be deleted as of the Effective Time. Following the Effective Time no holder of a
Company Stock Option or Company SAR or any participant in any Company Stock Plan
or other Company Benefit Plan will have any right thereunder to acquire any
capital stock of the Company or the Surviving Corporation.

                  SECTION 3.04. AUTHORITY; EXECUTION AND DELIVERY;
ENFORCEABILITY. (a) The Company has all requisite corporate power and authority
to execute and deliver this Agreement and, subject to receipt of the Company
Shareholder Approval, to consummate the Transactions. The execution and delivery
by the Company of this Agreement and, except as set forth in the next sentence,
the consummation by the Company of the Transactions have been duly authorized by
all necessary corporate action on the part of the Company, subject, in the case
of the consummation of the Merger, to receipt of the Company Shareholder
Approval. The Company has duly executed and delivered this Agreement and,
assuming due and valid authorization, execution and delivery hereof by Parent
and Sub, this Agreement constitutes its legal, valid and binding obligation,
enforceable against it in accordance with its terms, except that (i) such
enforcement may be subject to applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws, now or hereafter in effect, affecting creditor
rights generally and (ii) the remedy of specific performance and injunctive and
other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceedings therefor may be brought.

                  (b) The Board of Directors of the Company (the "COMPANY
BOARD"), at a meeting duly called and held, duly


<PAGE>

                                                                              15

and unanimously adopted resolutions (i) approving the Transaction Agreements,
the Offer, the Merger and the other Transactions, (ii) determining that the
terms of the Offer and the Merger and the other Transactions are fair to and in
the best interests of the Company's shareholders, (iii) recommending that the
holders of Company Common Stock accept the Offer and tender their shares of
Company Common Stock pursuant to the Offer, (iv) directing that this Agreement
be submitted to the Company's shareholders for approval and (v) recommending
that the Company's shareholders approve this Agreement; PROVIDED, HOWEVER, that
the Company Board may subsequently withdraw its recommendations referred to in
this Section 3.04(b) if it is permitted to do so under Section 5.02(b). Such
resolutions are sufficient to render the provisions of Article 13.03 of the TBCA
inapplicable to Parent and Sub and the Transaction Agreements, the Offer, the
Merger and the other Transactions. To the Company's knowledge, no other state
takeover statute or similar statute or regulation applies or purports to apply
to the Company with respect to the Transaction Agreements, the Offer, the Merger
or any other Transaction.

                  (c) The only vote of holders of any class or series of Company
capital stock necessary to approve and adopt this Agreement and the Merger is
the approval of this Agreement by the affirmative vote of the holders of at
least a majority of the outstanding Company Common Stock (the "COMPANY
SHAREHOLDER APPROVAL") and is only necessary in the event that the number of
shares of Company Common Stock tendered pursuant to the Offer represents less
than 90% of the issued and outstanding shares of Company Common Stock. The
affirmative vote of the holders of Company capital stock, or any of them, is not
necessary to approve any Transaction Agreement other than this Agreement or to
consummate the Offer or any Transaction other than the Merger.

                  SECTION 3.05. NO CONFLICTS; CONSENTS. (a) Except as set forth
in the Company Disclosure Letter, the execution and delivery by the Company of
this Agreement do not, and the consummation of the Offer, the Merger and the
other Transactions and compliance with the terms of this Agreement will not,
conflict with, or result in any violation of or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancelation or acceleration of any material obligation or to loss of a material
benefit under, or to increased, additional, accelerated or guaranteed rights or
entitlements of any person under, or

result in the creation of any Lien upon any of the properties or assets of the
Company or any Company Subsidiary under, any provision of (i) the Company
Charter, the Company By-laws or the comparable charter or organizational
documents of any Company Subsidiary, (ii) any Contract to which the Company or
any Company Subsidiary is a party or by which any of their respective properties
or assets is bound or (iii) subject to the filings and other matters referred to
in Section 3.05(b) and the receipt of the Company Shareholder Approval, any
judgment, order or decree ("JUDGMENT") or statute, law (including common law),
ordinance, rule or regulation ("LAW") applicable to the Company or any Company
Subsidiary or their respective properties or assets, except in the case of
clause (ii) or (iii) where such conflicts, violations or defaults, individually
and in the aggregate, would not reasonably be expected to have a Company
Material Adverse Effect.

                  (b) No consent, approval, license, permit, order or
authorization ("CONSENT") of, or registration, declaration or filing with, or
permit from, any Federal, state, local or foreign government or any court of
competent jurisdiction, administrative agency or commission or other
governmental authority or instrumentality, domestic or foreign (a "GOVERNMENTAL
ENTITY") is required to be obtained or made by or with respect to the Company or
any Company Subsidiary in connection with the execution, delivery and
performance of this Agreement or the consummation of the Transactions, other
than (i) compliance with and filings under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"), (ii) the filing of a joint
notification pursuant to Section 721(a) of the Defense Production Act of 1950,
as amended (the "EXON-FLORIO ACT"), (iii) the filing with the SEC of (A) the
Schedule 14D-9, (B) a proxy or information statement relating to the approval of
this Agreement by the Company's shareholders
(the "PROXY STATEMENT"), if such approval is required by Law, (C) any
information statement (the "INFORMATION STATEMENT") required under Rule 14f-1 in
connection with the Offer and (D) such reports under Sections 13 and 16 of the
Exchange Act as may be required in connection with the Transaction Agreements,
the Offer, the Merger and the other Transactions, (iv) the filing of the
Articles of Merger with the Secretary of State of the State of Texas and
appropriate documents with the relevant authorities of the other jurisdictions
in which the Company is qualified to do business, (v) compliance with and such
filings as may be required under applicable Environmental Laws (as

                                                                              17


defined in Section 3.14(a)), (vi) such filings as may be required in connection
with the taxes described in Section 6.08 and (vii) such other consents and
filings (the "OTHER COMPANY FILINGS") the failure of which to obtain or make,
individually and in the aggregate, would not reasonably be expected to have a
Company Material Adverse Effect or in any manner impede, frustrate, prevent,
delay or nullify the consummation of the Transactions.

                  SECTION 3.06. SEC DOCUMENTS AND FINANCIAL STATEMENTS. The
Company has filed all reports, schedules, forms, statements and other
documents required to be filed by the Company with the SEC since September
30, 1997 (the "COMPANY SEC DOCUMENTS"). As of its respective date, each
Company SEC Document complied in all material respects with the requirements
of the Exchange Act or the Securities Act of 1933, as amended (the
"SECURITIES ACT"), as the case may be, and the rules and regulations of the
SEC promulgated thereunder applicable to such Company SEC Document, and did
not, at the time such Company SEC Document was filed with the SEC, contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Except to the extent that information contained in any Company
SEC Document has been revised or superseded by a later-filed Company SEC
Document, none of the Company SEC Documents contains any untrue statement of
a material fact or omits to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. The unaudited
financial statements of the Company for its fiscal year ended September 30,
1999 (the "1999 COMPANY FINANCIAL STATEMENTS") are set forth in Section 3.06
of the Company Disclosure Letter. The 1999 Company Financial Statements and
the consolidated financial statements of the Company included in the Company
SEC Documents comply as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC
with respect thereto, have been prepared in accordance with generally
accepted accounting principles ("GAAP") (except as otherwise noted therein
including in the related notes and except, in the case of quarterly unaudited
statements, as permitted by Form 10-Q of the SEC and, in the case of 1999
Company Financial Statements, the absence of notes that would substantially
duplicate disclosure contained in the Filed Company SEC Documents) applied on
a consistent basis

                                                                              18


during the periods involved (except as may be indicated in the notes thereto)
and fairly present the consolidated financial position of the Company and its
consolidated subsidiaries as of the dates thereof and the consolidated results
of their operations and cash flows for the periods then ended (subject, in the
case of quarterly unaudited statements, to normal year-end audit adjustments).
Except as set forth in the 1999 Company Financial Statements and except for
liabilities and obligations incurred since the date of the 1999 Company
Financial Statements in the ordinary course of business or as set forth in the
Company Disclosure Letter, neither the Company nor any Company Subsidiary has
any material liabilities or obligations of any nature (whether accrued,
absolute, contingent or otherwise) required by GAAP to be set forth on a
consolidated balance sheet or in the notes thereto. None of the Company
Subsidiaries is, or has at any time since September 30, 1997 been, subject to
the reporting requirements of Section 13(a) or 15(d) of the Exchange Act.

                  SECTION 3.07. INFORMATION SUPPLIED. None of the information
supplied or to be supplied by the Company for inclusion or incorporation by
reference in (i) the Offer Documents, the Schedule 14D-9, the Other Filings (as
defined in Section 4.04) or the Information Statement will, at the time such
document is filed with the SEC or other Governmental Entity, at any time it is
amended or supplemented or at the time it is first published, sent or given to
the Company's shareholders, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, or (ii) the Proxy Statement will, at
the date it is first mailed to the Company's shareholders or at the time of the
Company Shareholders Meeting (as defined in Section 6.01(b)), contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading, except that no
representation is made by the Company with respect to statements made or
incorporated by reference therein based on information supplied by Parent or Sub
for inclusion or incorporation by reference therein. The Schedule 14D-9, the
Information Statement and the Proxy Statement will comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder.

                  SECTION 3.08. ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as
disclosed in the Company SEC Documents filed and publicly available prior to the
date of this Agreement (the "FILED COMPANY SEC DOCUMENTS") or in the Company
Disclosure Letter, since September 30, 1999, the Company has conducted its
business only in the ordinary course of business, and there has not been:

                  (i) any event, change, effect or development that,
         individually or in the aggregate, has had or would reasonably be
         expected to have a Company Material Adverse Effect, other than any
         event, change, effect or development to the extent attributable to (A)
         the economy or the securities markets in general, (B) this Agreement or
         the transactions contemplated hereby or the announcement thereof or (C)
         the Company's industry in general, and not specifically relating to the
         Company or the Company Subsidiaries;

                  (ii) any declaration, setting aside or payment of any dividend
         or other distribution (whether in cash, stock or property) with respect
         to any Company capital stock or any repurchase for value by the Company
         of any Company capital stock;

                  (iii) any split, combination or reclassification of any
         Company capital stock or any issuance or the authorization of any
         issuance of any other securities in respect of, in lieu of or in
         substitution for shares of Company capital stock;

                  (iv) (A) any granting by the Company or any Company Subsidiary
         to any director or officer of the Company or any Company Subsidiary of
         any increase in compensation, except in the ordinary course of business
         consistent with past practice or as was required under employment
         agreements filed as exhibits to the Filed Company SEC Documents, (B)
         any granting by the Company or any Company Subsidiary to any such
         director or officer of any increase in severance or termination pay,
         except as was required under any employment, severance or termination
         agreements filed as exhibits to the Filed Company SEC Documents, or (C)
         any entry by the Company or any Company Subsidiary into, or any
         amendment of, any employment, consulting, deferred compensation,
         indemnification, severance or termination agreement or
         arrangement with any such director or officer;


<PAGE>

                                                                              20


                  (v) any change in accounting methods, principles or practices
         by the Company or any Company Subsidiary materially affecting the
         consolidated assets, liabilities or results of operations of the
         Company, except insofar as may have been required by a change in GAAP;
         or

                  (vi) any material elections with respect to Taxes (as defined
         in Section 3.09(g)) by the Company or any Company Subsidiary or
         settlement or compromise by the Company or any Company Subsidiary of
         any material Tax liability or refund.

                  SECTION 3.09. TAXES. (a) The Company and each Company
Subsidiary have timely filed, or have caused to be timely filed (taking into
account any extension of time within which to file) on their behalf, all Tax
Returns required to be filed by them, other than those the failure of which to
file, individually and in the aggregate, has not had and would not reasonably be
expected to have a Company Material Adverse Effect, and all such Tax Returns are
true, complete and accurate in all material respects. All Taxes shown to be due
on such Tax Returns, or otherwise owed, have been timely paid, other than
failures to pay which, individually and in the aggregate, have not had and would
not reasonably be expected to have a Company Material Adverse Effect.

                  (b) The most recent financial statements contained in the
Filed Company SEC Documents reflect an adequate reserve for all Taxes payable by
the Company and the Company Subsidiaries for all Taxable periods and portions
thereof through the date of such financial statements. To the knowledge of the
Company and the Company Subsidiaries, no deficiency with respect to any Taxes
has been threatened, proposed, asserted or assessed against the Company or any
Company Subsidiary, and no requests for waivers of the time to assess any such
Taxes are pending.

                  (c) The Federal income Tax Returns of the Company and each
Company Subsidiary consolidated in such Returns have been examined by and
settled with the United States Internal Revenue Service for all years through
the fiscal year ended September 30, 1994. All assessments for Taxes due with
respect to such completed and settled examinations or any concluded litigation
have been fully paid.

                  (d) There are no material Liens for Taxes (other than for
current Taxes not yet due and payable and


<PAGE>

                                                                              21


Liens for Taxes that are being contested in good faith by appropriate
proceedings and for which adequate reserves are provided in accordance with GAAP
in the 1999 Company Financial Statements) on the assets of the Company or any
Company Subsidiary. Neither the Company nor any Company Subsidiary is bound by
any tax sharing agreement with another person with respect to Taxes.

                  (e) Other than the consolidated group in which the Company is
the parent, neither the Company nor any Company Subsidiary has any liability for
the payment of Taxes of any other entity as a result of being a member of an
affiliated, consolidated, combined or unitary group or as a result of any
express or implied obligation to indemnify any other person with respect to the
payment of any Taxes.

                  (f) Neither the Company nor any Company Subsidiary has engaged
in any transactions giving rise to deferred gain under Treas. Reg. Section
1.1502-13 that has not actually been included in taxable income for Federal
income Tax purposes by the date hereof.

                  (g) For purposes of this Agreement:

                  "TAXES" includes all forms of taxation, whenever created or
         imposed, and whether of the United States or elsewhere, and whether
         imposed by a local, municipal, governmental, state, foreign, Federal or
         other Governmental Entity, or in connection with any agreement with
         respect to Taxes, including all interest, penalties and additions
         imposed with respect to such amounts.

                  "TAX RETURN" means any Federal, state, local, provincial or
         foreign Tax return, declaration, statement, report, schedule, form or
         information return or any amended Tax return relating to Taxes.

                  SECTION 3.10. ABSENCE OF CHANGES IN BENEFIT PLANS. Except as
disclosed in the Filed Company SEC Documents or in the Company Disclosure
Letter, since September 30, 1998, there has not been any adoption or amendment
in any material respect by the Company or any Company Subsidiary of any
collective bargaining agreement or any bonus, pension, profit sharing, deferred
compensation, incentive compensation, stock ownership, stock purchase, stock
option, phantom stock, retirement, thrift, savings, stock bonus, restricted
stock, cafeteria, paid time off, perquisite, fringe benefit, vacation,
severance, disability, death benefit,

hospitalization, medical or other plan, arrangement or understanding (whether or
not legally binding) providing benefits to any current or former employee,
officer or director of the Company or any Company Subsidiary (collectively,

deferred compensation, indemnification, severance or termination agreements or
arrangements between the Company or any Company Subsidiary and any current or
former employee, officer or director of the Company or any Company Subsidiary
(collectively, "COMPANY BENEFIT AGREEMENTS").

                  SECTION 3.11. ERISA COMPLIANCE; EXCESS PARACHUTE PAYMENTS.
(a) The Company Disclosure Letter contains a list and brief description of all
"employee pension benefit plans" (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) (sometimes
referred to herein as "COMPANY PENSION PLANS"), "employee welfare benefit plans"
(as defined in Section 3(1) of ERISA) and all other Company Benefit Plans and
Company Benefit Agreements maintained, or contributed to, by the Company or any
Company Subsidiary, or to which the Company or any Company Subsidiary is a
party, for the benefit of any current or former employees, officers or directors

Proc. 93-39), to the effect that such Company Pension Plans are qualified and
exempt from Federal income taxes under Sections 401(a) and 501(a), respectively,

Company, has revocation been threatened, nor has any such Company Pension Plan
been amended since the date of its most recent determination letter or
application therefor in any respect that would adversely affect its
qualification or materially increase its costs. There is no material pending or,
to the knowledge of the Company, threatened litigation relating to the Company
Benefit Plans.

                  (c) Except as disclosed in the Company Disclosure Letter, no
Company Pension Plan, other than any Company Pension Plan that is a
"multiemployer plan" within the meaning of Section 4001(a)(3) of ERISA (a
"COMPANY MULTIEMPLOYER PENSION PLAN"), had, as of the respective last annual
valuation date for each such Company Pension Plan, any "unfunded benefit
liabilities" (as such term is defined in Section 4001(a)(18) of ERISA), based on
actuarial assumptions that have been furnished to Parent, and there has been no
material adverse change in the financial condition of any Company Pension Plan
since its last such annual valuation date. No liability under Subtitle C or D of
Title IV of ERISA has been or is expected to be incurred by the Company or any
Company Subsidiary with respect to any ongoing, frozen or terminated
"single-employer plan", within the meaning of Section 4001(a)(15) of ERISA,
currently or formerly maintained by any of them, or the single-employer plan of
any entity which is considered one employer with the Company under Section 4001
of ERISA or Section 414 of the Code (an "ERISA AFFILIATE"). None of the Company,
any Company Subsidiary, any officer of the Company or any Company Subsidiary or
any of the Company Benefit Plans which are subject to ERISA, including the
Company Pension Plans, any trusts created thereunder or any trustee or
administra tor thereof, has engaged in a "prohibited transaction" (as such term
is defined in Section 406 of ERISA or Section 4975 of the Code) or any other
breach of fiduciary responsibility that could subject the Company, any Company
Subsidiary or any officer of the Company or any Company Subsidiary to the tax or
penalty on prohibited transactions imposed by such Section 4975 or to any
liability under Section 502(i) or 502(l) of ERISA. None of such Company Benefit
Plans and trusts has been terminated, nor has there been any "reportable event"
(as that term is defined in Section 4043 of ERISA) for which the 30-day
reporting requirement has not been waived with respect to any Company Benefit
Plan during the last five years, and no notice of a reportable event will be
required to be filed in connection with the Transactions. Neither the Company
nor any Company Subsidiary has incurred a "complete

                                                                              24


withdrawal" or a "partial withdrawal" (as such terms are defined in Sections
4203 and 4205, respectively, of ERISA) since the effective date of such Sections
4203 and 4205 with respect to any Company Multiemployer Pension Plan. All
contributions and premiums required to be made under the terms of any Company
Benefit Plan as of the date hereof have been timely made or have been reflected
on the most recent consolidated balance sheet filed or incorporated by reference
in the Filed Company SEC Documents. Neither any Company Pension Plan nor any
single-employer plan of an ERISA Affiliate has an "accumulated funding
deficiency" (as such term is defined in Section 302 of ERISA or Section 412 of
the Code), whether or not waived.

                  (d) With respect to any Company Benefit Plan that is an
employee welfare benefit plan, except as disclosed in the Company Disclosure
Letter, (i) no such Company Benefit Plan is unfunded or funded through a
"welfare benefit fund" (as such term is defined in Section 419(e) of the Code),
(ii) each such Company Benefit Plan that is a "group health plan" (as such term
is defined in Section 5000(b)(1) of the Code), complies with the applicable
requirements of Section 4980B(f) of the Code and (iii) each such Company Benefit
Plan (including any such Plan covering retirees or other former employees) may
be amended or terminated without material liability to the Company and the
Company Subsidiary on or at any time after the Effective Time. Neither the
Company nor any Company Subsidiary has any obligations for retiree health and
life benefits under any Company Benefit Plan or Company Benefit Agreement.

                  (e) Except as disclosed in the Company Disclosure Letter, the
consummation of the Offer, the Merger or any other Transaction will not (x)
entitle any employee, officer or director of the Company or any Company
Subsidiary to severance pay, (y) accelerate the time of payment or vesting or
trigger any payment or funding (through a grantor trust or otherwise) of
compensation or benefits under, increase the amount payable or trigger any other
material obligation pursuant to, any of the Company Benefit Plans or Company
Benefit Agreements other than pursuant to the provisions of Section 6.04 hereof
or (z) result in any breach or violation of, or a default under, any of the
Company Benefit Plans or Company Benefit Agreements.

                  (f) Other than payments that may be made to the persons listed
in the Company Disclosure Letter (the "PRIMARY COMPANY EXECUTIVES"), any amount
or economic

                                                                              25

benefit that could be received (whether in cash or property or the vesting of
property) as a result of the Offer, the Merger or any other Transaction
(including as a result of termination of employment on or following the
Effective Time) by any employee, officer or director of the Company or any of
its affiliates who is a "disqualified individual" (as such term is defined in
proposed Treasury Regulation Section 1.280G-1) under any Company Benefit Plan or
Company Benefit Agreement or otherwise would not be characterized as an "excess
parachute payment" (as defined in Sec tion 280G(b)(1) of the Code), and no
disqualified individual is entitled to receive any additional payment from the
Company or any Company Subsidiary or any other person in the event that the
excise tax under Section 4999 of the Code is imposed on such disqualified
individual. Set forth in the Company Disclosure Letter is (i) the estimated
maximum amount that could be paid to each Primary Company Executive as a result
of the Offer, the Merger and the other Transactions under all Company Benefit
Plans and Company Benefit Agreements and (ii) the "base amount" (as defined in
Section 280G(b)(3) of the Code) for each Primary Company Executive calculated as
of the date of this Agreement.

                  SECTION 3.12. LITIGATION. The Company Disclosure Letter sets
forth a true and complete description of all pending, or, to the knowledge of
the Company, threatened, material suits, actions, proceedings or Judgments
against or affecting the Company or any Company Subsidiary and a summary of the
status of and potential liabilities arising from each such suit, action,
proceeding and Judgment. Except as set forth in the Company Disclosure Letter or
in the Filed Company SEC Documents, there is (i) no investigation or review by
any Governmental Entity or self-regulatory authority with respect to the Company
or any Company Subsidiary or any of their respective employees or
representatives (insofar as any such investigation or review relates to their
activities with the Company or any Company Subsidiary) actually pending or, to
the knowledge of the Company, threatened, nor has any Governmental Entity or
self-regulatory authority indicated to the Company or any Company Subsidiary an
intention to conduct the same, (ii) no material claim, action, suit or
proceeding (including any claim, action, suit or proceeding pertaining to
product liability, patent infringement or bodily injury) pending, or, to the
knowledge of the Company, threatened against or affecting the Company or any
Company Subsidiary, the business or assets of the Company or any Company
Subsidiary or any of the directors, shareholders,

employees or representatives of the Company or any Company Subsidiary (insofar
as any such matters relate to their activities with the Company or any Company
Subsidiary) at law or in equity, or before any Governmental Entity, arbitrator
or arbitration panel and (iii) no outstanding Judgment by which the Company or
any Company Subsidiary or their respective business is bound or by which any of
the employees or representatives of the Company or any Company Subsidiary is
prohibited or restricted from engaging in or otherwise conducting the business
of the Company or any Company Subsidiary as presently conducted, except where
such investigations, reviews, claims, actions, suits, proceedings or Judgments,
individually and in the aggregate, have not had and would not reasonably be
expected to have a Company Material Adverse Effect.

                  SECTION 3.13. COMPLIANCE WITH APPLICABLE LAWS. Except as
disclosed in the Filed Company SEC Documents or in the Company Disclosure
Letter, the Company and the Company Subsidiaries are in compliance in all
material respects with all applicable Laws (including the Truth-In-Negotiations-
Act, the Procurement Integrity Act, the Foreign Corrupt Practices Act, the Cost
Accounting Standards, the Regulations of applicable Governmental Entities
governing foreign military sales, export controls, illegal boycotts, national
security and any other Laws or orders incorporated expressly, by reference or by
operation of Law into, or otherwise applicable to, any Contract or other
agreement made with the United States of America (a "GOVERNMENT CONTRACT")).
Except as set forth in the Filed Company SEC Documents or in the Company
Disclosure Letter, neither the Company nor any Company Subsidiary has received
any written notice: (i) since September 30, 1997, of any administrative, civil

Entity (including any qui tam action brought under the Civil False Claims Act
alleging any irregularity, misstatement or omission arising under or relating to
any Government Contract) relating to the Company or any Company Subsidiary or
(ii) during the past two years, from any Governmental Entity alleging that the
Company or a Company Subsidiary is not in compliance in any material respect
with any applicable Law. Except as set forth in the Company Disclosure Letter,
since September 30, 1997, to the knowledge of the Company, neither the Company
nor any Company Subsidiary nor any of their respective officers or directors is
or has been the subject of any criminal investigation in respect of any
Government Contract. Each of the Company, the Company Subsidiaries and their
respective employees has in effect

necessary for it to own, lease or operate its properties and assets and to carry
on its business and operations as now conducted, except for the failure to have
such Permits that, individually and in the aggregate, has not had and would not

occurred no defaults under, or violations of, any such Permit, except for such
defaults and violations that, individually and in the aggregate, have not had
and would not reasonably be expected to have a Company Material Adverse Effect.
Neither the Offer nor the Merger, in and of itself, would cause the revocation
or cancelation of any such Permit that individually or in the aggregate would
reasonably be expected to have a Company Material Adverse Effect. This Section
3.13 does not relate to matters with respect to Taxes, which are the subject of
Section 3.09, or to environmental matters, which are the subject of Section
3.14.

                  SECTION 3.14. ENVIRONMENTAL MATTERS. (a) Except as disclosed

or facility in a manner that has given or would reasonably be expected to give
rise to material liabilities, including any material liability for response
costs, corrective

attorney fees, pursuant to any Environmental Laws. "ENVIRONMENTAL LAWS" means
any applicable Federal, state or local statutes, regulations, ordinances and
other provisions having the force or effect of law, all judicial and

Governmental Entity, the placement of any notice, acknowledgment or covenant in
any land records, or the modification of or provision of notice under any
agreement, consent order or consent decree. No Lien has been placed upon any of
the Company's or any of the Company Subsidiaries' properties under any
Environmental Law.

                  SECTION 3.15. CONTRACTS. (a) Except as filed as an exhibit to
the Filed Company SEC Documents or as set forth in the Company Disclosure
Letter, there are no Contracts that are material to the business, assets,
condition (financial or otherwise) or results of operations of the Company and
the Company Subsidiaries taken as a whole. Neither the Company nor any Company
Subsidiary is in violation of or in default under (nor does there exist any
condition which upon the passage of time or the giving of notice would cause
such a violation of or default under) any Contract to which it is a party or by
which it or any of its properties or assets is bound, except for violations or
defaults that, individually and in the aggregate, have not had and would not
reasonably be expected to have a Company Material Adverse Effect. Except as set

         Property, except for agreements relating to computer software licensed
         to the Company or a Company Subsidiary in the ordinary course of
         business; or

                  (vii) other Contract or commitment to which the Company or any

Neither the Company nor any Company Subsidiary has any pending default
termination action, open written cure notice or show cause notice (as defined in
the Federal Acquisition Regulations Part 49, P. 49.607(a) and (b), respectively)
in respect of any Government Contract. Except as disclosed in the Filed Company
SEC Documents or set forth in the Company Disclosure Letter, there are no

Contracts by any Governmental Entities. Neither the Company nor any Company
Subsidiary nor any of their respective directors and officers is (or during the
past five years has been) suspended or debarred from doing business with the
U.S. government or is (or during such period was) the subject of a finding of
nonresponsibility or ineligibility for U.S. government contracting. The Company

their obligations relating to any equipment or fixtures owned by any

                  (b) Except as set forth in the Company Disclosure Letter, the
Company and each Company Subsidiary have complied in all material respects with
the terms of all material leases to which they are parties and under which they

PROPERTY") that is, individually or in the aggregate, material to the conduct of
the business of the Company and the Company Subsidiaries taken as a whole, and
the consummation of the Transactions will not conflict with, alter or impair any
such rights. All Intellectual Property held by the Company and the Company
Subsidiaries is valid and enforceable and (i) neither the Company nor any
Company Subsidiary is, nor will the Company or any Company Subsidiary be as a
result of the execution and delivery of this Agreement or the performance of the

are pending or, to the knowledge of the Company, threatened that the Company or
any Company Subsidiary is infringing on or otherwise violating, the rights of
any person with regard to any Intellectual Property and (ii) to the knowledge of
the Company, no person is infringing on or otherwise violating any right of the

HOWEVER, that prior to the earlier to occur of acceptance for payment of shares
of Company Common Stock pursuant to the Offer and approval of this Agreement by
the shareholders of the Company, the Company may, to the extent that a failure

applicable Law, as determined in good faith by a majority of the Disinterested
Directors based on the advice of outside counsel, in response to a Superior
Company Proposal (as defined in Section 5.02(e)) that was not solicited by the
Company or its Representatives and that did not otherwise result from a breach
or a deemed breach of this Section 5.02(a), and subject to compliance with
Section 5.02(c), (x) furnish information with respect to the Company to the

restrictions set forth in the preceding sentence by any Representative or

to enter into any letter of intent, agreement in principle, acquisition
agreement or similar agreement (each, an "ACQUISITION AGREEMENT") relating to

of Company Common Stock pursuant to the Offer and approval of this Agreement by
the shareholders of the Company, the Company Board receives a Superior Company
Proposal which was not solicited by the Company and which did not otherwise
result from a breach of Section 5.02(a), and the Company Board determines in
good faith,

Superior Company Proposal.

                  (c) The Company promptly shall advise Parent orally and in
writing of any Company Takeover Proposal or any inquiry with respect to, or that
could reasonably be expected to lead to, any Company Takeover Proposal
(including any change to the terms of any such Company Takeover Proposal or
inquiry) and the identity of the person making any such Company Takeover
Proposal or inquiry. The Company shall (i) keep Parent fully informed of the
status of any such Company Takeover Proposal or inquiry (including any change to
the terms of any such Company Takeover Proposal or inquiry) and (ii) provide to
Parent copies of all correspondence and other written material sent or provided
by any third party to the Company, or by the Company to any third party, in
connection with any Company Takeover Proposal, as soon as practicable after

                  (d) Nothing contained in Section 5.02(a) or 5.02(b) shall
prohibit the Company from (x) taking and disclosing to its shareholders a
position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or (y)
making any disclosure to the Company's shareholders if, in the good faith
judgment of the Company Board, based on the advice of outside counsel, failure
so to disclose would constitute a violation of applicable Law; PROVIDED,
HOWEVER, that neither the Company, nor the Company Board nor any committee
thereof shall withdraw or modify, or propose publicly to withdraw or modify, its
position with respect to the Transaction Agreements, the Offer or the Merger
(unless it is permitted to do so under Section 5.02(b)) or approve or recommend,
or propose publicly to approve or recommend, a Company Takeover Proposal.

         all or substantially all its assets or otherwise, (i) on terms which
         the Company Board determines in its good faith judgment to be superior
         from a financial point of view to the holders of Company Common Stock
         than the Transactions (based on the written opinion, with only
         customary qualifications, of the Company's independent financial
         advisor, which has been provided to Parent), taking into account all
         the terms and conditions of such proposal, the Transaction Agreements
         and any proposal by Parent to amend the terms of the Transactions, (ii)
         for which financing, to the extent required, is then committed or
         which, in the good faith judgment of the Company Board, is reasonably
         capable of being obtained by such third party and (iii) for which, in
         the good faith judgment of the Company Board, no regulatory approvals
         are required, including antitrust approvals, that could not reasonably
         be expected to be obtained.

                  SECTION 6.01. PREPARATION OF PROXY STATEMENT; SHAREHOLDERS'
MEETING. (a) If the approval of this Agreement by the Company's shareholders is
required by Law, the Company shall, as soon as practicable following the
acceptance for payment and purchase of the shares of


<PAGE>

                                                                             45


Company Common Stock by Sub pursuant to the Offer, prepare and file with the SEC
the Proxy Statement in preliminary form, and each of the Company and Parent
shall use its reasonable efforts to respond as promptly as practicable to any
comments of the SEC with respect thereto. The Company shall notify Parent
promptly of the receipt of any comments from the SEC or its staff and of any
request by the SEC or its staff for amendments or supplements to the Proxy
Statement or for additional information and shall supply Parent with copies of
all correspondence between the Company or any of its representatives, on the one
hand, and the SEC or its staff, on the other hand, with respect to the Proxy
Statement. If at any time prior to receipt of the Company Shareholder Approval
there shall occur any event that should be set forth in an amendment or
supplement to the Proxy Statement, the Company shall promptly prepare and mail
to its shareholders such an amendment or supplement. No filing of, or amendment
to, the Proxy Statement will be made by the Company without providing Parent the
opportunity to review and comment thereon. The Company shall not mail any Proxy
Statement, or any amendment or supplement thereto, to which Parent reasonably
objects. The Company shall use its reasonable efforts to cause the Proxy
Statement to be mailed to the Company's shareholders as promptly as practicable
after filing with the SEC.

                  (b) If the approval of this Agreement by the Company's
shareholders is required by Law, the Company shall, as soon as practicable
following the acceptance for payment and purchase of the shares of Company
Common Stock by Sub pursuant to the Offer, duly call, give notice of, convene
and hold a meeting of its shareholders (the "COMPANY SHAREHOLDERS' MEETING") for
the purpose of seeking the Company Shareholder Approval. The Company shall,
through the Company Board, recommend to its shareholders that they vote in favor
of the approval of this Agreement and the Company Board shall not condition its
submission to the shareholders of this Agreement on any basis; PROVIDED,
HOWEVER, that the Company Board may withdraw such recommendation if it is
permitted to do so under Section 5.02(b). Without limiting the generality of the
foregoing, the Company agrees that its obligations pursuant to the first
sentence of this Section 6.01(b) shall not be affected by the commencement,
public proposal, public disclosure or communication to the Company of any
Company Takeover Proposal. Notwithstanding the foregoing, if Sub or any other
subsidiary of Parent shall acquire at least 90% of the outstanding shares of
Company Common Stock, the parties


<PAGE>

                                                                            46


shall, at the request of Parent, take all necessary and appropriate action to
cause the Merger to become effective as soon as practicable after the expiration
of the Offer without a shareholders' meeting in accordance with Article 5.16 of
the TBCA.

                  (c) Parent shall cause all shares of Company Common Stock
purchased pursuant to the Offer and all other shares of Company Common Stock
owned by Sub or any other subsidiary of Parent to be voted in favor of the
approval of this Agreement.

                  SECTION 6.02. ACCESS TO INFORMATION; CONFIDENTIALITY. From the
date hereof until the earlier of the Effective Time or the termination of this
Agreement, upon reasonable notice the Company shall, and shall cause each
Company Subsidiary to, afford to Parent, and to Parent's officers, employees,
accountants, counsel, financial advisors and other representatives, reasonable
access during reasonable business hours to (i) all their respective properties,
books, contracts, commitments, personnel and records and other information and
business documents, (ii) customers of the Company or any Company Subsidiary as
may reasonably be designated by Parent and (iii) the premises of the Company and
the Company Subsidiaries for the purpose of inspecting the assets and facilities
of any such entity and the condition thereof, provided that access to the
premises shall be permitted only with the prior consent of the Company (which
consent shall not be unreasonably withheld). During the period prior to the
Effective Time, the Company shall, and shall cause each Company Subsidiary to,
furnish promptly to Parent (a) a copy of each report, schedule, registration
statement and other document filed by it during such period pursuant to the
requirements of Federal or state securities laws and (b) consistent with its
legal obligations, all other information concerning its business, properties and
personnel as Parent may reasonably request. Without limiting the generality of
the foregoing, the Company shall, within two business days of request therefor,
provide to Parent the information described in Rule 14a-7(a)(2)(ii) under the
Exchange Act and any information to which a shareholder of the Company would be
entitled under Article 2.44 of the TBCA (assuming such holder met the
requirements of such section). During the period prior to the Effective Time,
Parent will have the reasonable cooperation of the Company in confirming the
nature of the relationships between the Company or any Company Subsidiary and
their respective customers and suppliers, including whether or not such
relationships are satisfactory and whether or not such relationships

                                                                           47


are expected to continue after the Merger. The Company shall have the right to
have a representative present at all times of any such inspections, interviews
and communications conducted by Parent or its representatives. Neither any
investigation conducted by Parent or its representatives pursuant to this
Section 6.02 nor the results thereof shall affect any representation or warranty
of the Company contained in this Agreement or the ability of Parent to rely
thereon. All information exchanged pursuant to this Section 6.02 shall be
subject to the confidentiality agreement dated September 28, 1999, between the
Company and Parent (the "CONFIDENTIALITY AGREEMENT").

                  SECTION 6.03. REASONABLE EFFORTS; NOTIFICATION. (a) Upon the
terms and subject to the conditions set forth in this Agreement, each of the
parties shall use all reasonable efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things necessary, proper or advisable to consummate
and make effective, in the most expeditious manner practicable, the Offer, the
Merger and the other Transactions, including (i) the obtaining of all necessary
actions or nonactions, waivers, consents and approvals from Governmental
Entities and the making of all necessary registrations and filings (including
filings with Governmental Entities, if any) and the taking of all reasonable
steps as may be necessary to obtain an approval or waiver from, or to avoid an
action or proceeding by, any Governmental Entity, (ii) the obtaining of all
necessary consents, approvals or waivers from third parties, (iii) the defending
of any lawsuits or other legal proceedings, whether judicial or administrative,
challenging the Transaction Agreements or the consummation of the Transactions,
including seeking to have any stay or temporary restraining order entered by any
court or other Governmental Entity vacated or reversed and (iv) the execution
and delivery of any additional instruments necessary to consummate the
Transactions and to fully carry out the purposes of the Transaction Agreements;
PROVIDED, HOWEVER, that Parent shall not be required to consent to any action
described in paragraph (a) of Exhibit A to this Agreement. In connection with
and without limiting the foregoing, the Company and the Company Board shall (i)
take all action necessary to ensure that no state takeover statute or similar
statute or regulation is or becomes applicable to any Transaction or the
Transaction Agreements, (ii) if any state takeover statute or similar statute or


<PAGE>

                                                                          48


regulation becomes applicable to the Transaction Agreements, take all action
necessary to ensure that the Offer, the Merger and the other Transactions may be
consummated as promptly as practicable on the terms contemplated by the
Transaction Agreements and otherwise to minimize the effect of such statute or
regulation on the Offer, the Merger and the other Transactions and (iii)
cooperate with Parent and Sub in the arrangements for obtaining the Financing.
Nothing in this Agreement shall be deemed to require Parent to waive any
substantial rights or agree to any substantial limitation on its operations or
to dispose of any asset or collection of assets of the Company, Parent or any of
their respective subsidiaries or affiliates. Notwithstanding the foregoing, the
Company shall not be prohibited under this Section 6.03(a) from taking any
action permitted by Section 5.02.

                  (b) The Company shall give prompt notice to Parent, and Parent
or Sub shall give prompt notice to the Company, of (i) any representation or
warranty made by it contained in any Transaction Agreement that is qualified as
to materiality becoming untrue or inaccurate in any respect or any such
representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect or (ii) the failure by it to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under any Transaction Agreement; PROVIDED,
HOWEVER, that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under the Transaction Agreements.

                  SECTION 6.04. STOCK OPTIONS. (a) As soon as practicable
following the date of this Agreement, the Company Board (or, if appropriate, any
committee administering the Company Stock Plans) shall adopt such resolutions or
take such other actions as are required to adjust the terms of all outstanding
Company Stock Options and all outstanding Company SARs to provide that (i) each
outstanding Company Stock Option may be exercised, whether or not such Company
Stock Option is vested, immediately prior to the acceptance for payment of
shares of Company Common Stock pursuant to



<PAGE>

                                                                          49


the Offer, contingent on and subject to the consummation of the Offer, PROVIDED
that the shares of Company Common Stock issued upon such exercise are tendered
into the Offer and not withdrawn and (ii) each Company Stock Option and Company
SAR outstanding that is not exercised prior to the acceptance for payment of
shares of Company Common Stock pursuant to the Offer shall be canceled effective
immediately prior to the acceptance for payment of shares of Company Common
Stock pursuant to the Offer with the holder thereof becoming entitled to receive
an amount of cash equal to the product of (x) the excess, if any, of (A) the Per
Share Merger Consideration over (B) the exercise price per share of Company
Common Stock subject to such Company Stock Option or Company SAR, multiplied by
(y) the number of shares of Company Common Stock issuable pursuant to the
unexercised portion of such Company Stock Option or Company SAR; PROVIDED,
HOWEVER, that no cash payment shall be made with respect to any Company SAR that
is related to a Company Stock Option in respect of which such a cash payment is
made. All amounts payable pursuant to this Section 6.04 shall be subject to any
required withholding of Taxes or proof of eligibility of exemption therefrom and
shall be paid at or as soon as practicable following the Effective Time, but in
any event within one business day following the Effective Time, without
interest.

                  (b) The Company shall use its best efforts to obtain all
consents of the holders of the Company Stock Options, if such consents are
determined to be necessary to effectuate the foregoing as mutually agreed by
Parent and the Company. The cancelation of a Company Stock Option in exchange
for the cash payment described in this Section 6.04 shall be deemed a release of
any and all rights the holder of such Company Stock Option had or may have had
in respect thereof, and any necessary consents from all such holders shall so
provide. Notwithstanding anything to the contrary contained in this Agreement,
payment shall, at Parent's request, be withheld in respect of any Company Stock
Option until all necessary consents are obtained.

                  (c) As soon as practicable following the date of this
Agreement, the Company Board (or, if appropriate, any committee administering
the Company Stock Plans) shall take or cause to be taken such actions as are
required to cause (x) the Company Stock Plans to terminate as of the Effective
Time and (y) the provisions in any other Company Benefit Plan providing for the
issuance, transfer or grant of any capital stock of the Company or any interest
in respect of any capital stock of the Company to be deleted as of the Effective
Time. The Company shall ensure that following the Effective Time no holder of a
Company Stock Option or Company SAR or any participant in any Company Stock Plan
or other Company Benefit Plan shall have any right thereunder to


<PAGE>

                                                                          50


acquire any capital stock of the Company or the Surviving Corporation.

                  (d) The Company shall take or cause to be taken all actions
required to cause the TIW Systems, Inc. Stock Bonus Plan to be amended as of
immediately prior to the Effective Time to provide that, in the event the
Company Common Stock ceases to be readily tradable (within the meaning of
Q/A-2(d)(1)(iv)(A) of Treas. Reg. Section 1.411(d)-4), distributions of benefits
under such plan shall be in the form of cash; PROVIDED that the foregoing shall
not apply in the event that prior to the Effective Time (i) such plan has
received a favorable determination letter from the Internal Revenue Service in
respect of the termination of the plan, (ii) such plan has been terminated and
(iii) all benefits payable under such plan have been paid in full to each plan
participant and beneficiary entitled to receive benefits in respect of the
termination of such plan.

                  (e) In this Agreement:

                  "COMPANY STOCK OPTION" means any option to
         purchase Company Common Stock granted under any Company
         Stock Plan.

                  "COMPANY SAR" means any stock appreciation right linked to the
         price of Company Common Stock and granted under any Company Stock Plan.

                  "COMPANY STOCK PLANS" means the Company's 1995 Stock
         Compensation Plan, the Company's Stock Option Plan for Key Employees,
         the Company's Non-Employee Directors Stock Option Plan and the
         Company's Outside Directors Stock Option Plan, in each case as amended
         from time to time.

                  SECTION 6.05. INDEMNIFICATION. (a) For six years after the
Effective Time, the Surviving Corporation (or any successor to the Surviving
Corporation) shall honor all the Company's obligations to indemnify, defend and
hold harmless the present and former officers and directors] of the Company and
the Company Subsidiaries and the other individual identified as an indemnified
party in the Company Disclosure Letter (each an "INDEMNIFIED PARTY") against
losses, claims, damages, liabilities, costs, fees and expenses (including
reasonable fees and disbursements of counsel and judgments, fines, losses,
claims, liabilities and amounts paid in settlement PROVIDED that any such
settlement is effected with the written consent of Parent or the


<PAGE>

                                                                       51
Surviving Corporation, which consent shall not unreasonably be withheld)
arising out of actions or omissions occurring at or prior to the Effective Time
("LOSSES") to the extent such obligations of the Company exist under the TBCA,
the terms of the Company Charter or the Company By-laws, in each case as in
effect on the date of this Agreement, or under any Indemnification Agreement
between the Company or any Company Subsidiary, as applicable, and the
Indemnified Party that has been filed as an exhibit to the Filed Company SEC
Documents or that has been previously delivered to Parent and is listed in the
Company Disclosure Letter; PROVIDED that in the event any claim or claims are
asserted or made within such six-year period, all rights to indemnification in
respect of any such claim or claims shall continue until disposition of any and
all such claims.

                  (b) (i) Promptly after the receipt by any Indemnified Party of
notice of any claim, the Indemnified Party will give the Surviving Corporation
written notice of such claim or the commencement of such action or proceeding
and shall permit the Surviving Corporation to assume the defense of any such
claim or any proceeding or litigation resulting from such claim, unless the
action or proceeding seeks an injunction or other similar relief against the
Indemnified Party or there is a conflict of interest (requiring separate
representation under applicable principles of professional responsibility)
between the Indemnified Party and the Surviving Corporation in the conduct of
the defense of such action. Failure by the Surviving Corporation to notify the
Indemnified Party of the Surviving Corporation's election to defend any such
proceeding or action within a reasonable time, but in no event more than 10 days
after written notice thereof shall have been given to the Surviving Corporation,
shall be deemed a waiver by the Surviving Corporation of its right to defend
such action. Failure by the Indemnified Party to notify the Surviving
Corporation of any claim for indemnification shall not relieve the Surviving
Corporation of any liability that the Surviving Corporation may have to the
Indemnified Party, except to the extent the Surviving Corporation demonstrates
that the defense of such claim or action has been prejudiced thereby.

                  (ii) If the Surviving Corporation assumes the defense of any
such claim or litigation resulting therefrom with counsel reasonably acceptable
to the Indemnified Party, the obligations of the Surviving Corporation as to
such claim shall be limited to the defense or settlement of such claim or
litigation


<PAGE>

                                                                            52


resulting therefrom and to holding the Indemnified Party harmless against any
Losses to the extent required by this Section 6.05. The Indemnified Party may
participate, at the Indemnified Party's expense, in the defense of such claim or
litigation PROVIDED that the Surviving Corporation shall direct and control the
defense of such claim or litigation. The Indemnified Party shall cooperate and
make available all books and records reasonably necessary and useful in
connection with the defense. The Surviving Corporation shall not, in the defense
of such claim or any litigation resulting therefrom, consent to entry of any
judgment or enter into any settlement, unless the Indemnified Party shall be
fully released and discharged, except with the written consent of the
Indemnified Party.

                  (iii) If the Surviving Corporation shall not assume the
defense of any such claim or litigation resulting therefrom, the Indemnified
Party may defend against such claim or litigation in such manner as the
Indemnified Party may deem appropriate and reasonably satisfactory to the
Surviving Corporation. The Surviving Corporation shall promptly reimburse the
Indemnified Party for the amount of all reasonable expenses, legal or otherwise,
incurred by the Indemnified Party in connection with the defense against or
settlement of such claim or litigation; PROVIDED, HOWEVER, that the Surviving
Corporation shall be required to reimburse such amounts only after receiving an
undertaking from the Indemnified Party to repay such amounts if it is determined
that the Indemnified Party is not entitled to indemnification therefor. The
Surviving Corporation shall not be liable for any Losses resulting from any
settlement or compromise of, or offer to settle or compromise, any claim or
litigation or other action without the prior written consent of the Surviving
Corporation, which consent shall not be unreasonably withheld.

                  (c) In the event that the Surviving Corporation or any of its
successors or assigns (i) consolidates with or merges into any other person and
is not the continuing or surviving corporation or entity of such consolidation
or merger or (ii) transfers or conveys all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provision will be made so that the successors and assigns of the Surviving
Corporation shall expressly assume the obligations set forth in this Section
6.05.

                                                                            53

                  (d) The provisions of this Section 6.05 are (i) intended to be
for the benefit of, and to be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives and (ii) in addition to, and not in
substitution for, any other rights to indemnification or contribution that any
such person may have by contract or otherwise.

                  SECTION 6.06. FEES AND EXPENSES. (a) Except as provided below,
all fees and expenses incurred in connection with the Merger and the other
Transactions shall be paid by the party incurring such fees or expenses, whether
or not the Merger is consummated.

                  (b) In the event that (1) (A) a Company Takeover Proposal
shall have been made known to the Company or shall have been made directly to
its shareholders or any person shall have announced an intention (whether or not
conditional) to make a Company Takeover Proposal, (B) thereafter this Agreement
is terminated pursuant to Section 8.01(b)(ii), 8.01(b)(iii) or 8.01(c) and (C)
within 12 months after such termination a Company Takeover Transaction is
consummated or the Company (or one or more Company Subsidiaries representing in
the aggregate 20% or more of the net revenues, net income or the assets of the
Company and the Company Subsidiaries, taken as a whole) enters into an
Acquisition Agreement with respect to, approves or recommends a Company Takeover
Transaction or (2) this Agreement is terminated by the Company pursuant to
Section 8.01(e) or by Parent or Sub pursuant to Section 8.01(d), then the
Company shall promptly, but in no event later than, in the case of clause (1),
the date of the earliest to occur of such consummation, approval or
recommendation of a Company Takeover Transaction or the entering into of such
Acquisition Agreement, or in the case of clause (2), the date of such
termination, pay to Parent a fee equal to $3,840,000 (three million eight
hundred forty thousand dollars) (the "TERMINATION FEE"), payable by wire
transfer of same day funds.

                  (c) If the Company is required to pay to Parent a fee pursuant
to Section 6.06(b), the Company shall reimburse Parent and Sub for all their
out-of-pocket expenses actually incurred in connection with the Transaction
Agreements, the Offer, the Merger and the other Transactions in an amount not to
exceed $640,000 (six hundred forty thousand dollars). Such reimbursement shall
be paid upon demand following termination of this Agreement.

                                                                            54


                  (d) The Company acknowledges that the agreements contained in
this Section 6.06 are an integral part of the Transactions, and that, without
these agreements, Parent and Sub would not enter into the Transaction
Agreements. Accordingly, if the Company fails promptly to make a payment due
pursuant to this Section 6.06, and, in order to obtain such payment, Parent or
Sub commences a suit which results in a judgment against the Company, the
Company shall pay to Parent and Sub their reasonable costs and expenses
(including attorneys' fees and expenses) in connection with such suit, together
with interest on the amount set forth in this Section 6.06 at the prime rate of
First Union National Bank in effect on the date such payment was required to be
made. The Company acknowledges and agrees that the payment of any amounts due
pursuant to this Section 6.06 shall not constitute the exclusive remedy of
Parent and Sub under the Transaction Agreements. Without limiting the generality
of the foregoing, in the event of a breach or deemed breach by the Company of
Section 5.02, Parent and Sub shall be entitled to the remedies set forth in
Section 9.10, including an injunction, and all other remedies available at law
or in equity to which Parent and Sub are entitled.

                  SECTION 6.07. PUBLIC ANNOUNCEMENTS. Parent and Sub, on the one
hand, and the Company, on the other hand, shall consult with each other before
issuing, and provide each other the opportunity to review and comment upon, any
press release or other public statements with respect to the Offer, the Merger
and the other Transactions and shall not issue any such press release or make
any such public statement prior to such consultation, except as may be required
by applicable Law, court process or by obligations pursuant to any listing
agreement with any national securities exchange. Within three business days
after the Announcement Date, the Company shall issue a press release, in the
form previously delivered to Parent, reporting its results for the fiscal year
ended September 30, 1999, and, as promptly as practicable but in no event later
than three business days after the Announcement Date, the Company shall file
such press release with the SEC as an exhibit to a Current Report on Form 8-K.

                  SECTION 6.08. TRANSFER TAXES. All stock transfer, real estate
transfer, documentary, stamp, recording and other similar Taxes (including
interest, penalties and additions to any such Taxes) ("TRANSFER TAXES") incurred
in connection with the Transactions shall be paid by either Sub or the Surviving
Corporation,


<PAGE>

                                                                           55


and the Company shall cooperate with Sub and Parent in preparing, executing and
filing any Tax Returns with respect to such Transfer Taxes, including supplying
in a timely manner a complete list of all real property interests held by the
Company and any information with respect to such property that is reasonably
necessary to complete such Tax Returns.

                  SECTION 6.09. DIRECTORS. Promptly upon the acceptance for
payment of, and payment by Sub for, any shares of Company Common Stock pursuant
to the Offer, Sub shall be entitled to designate such number of directors on the
Company Board as will give Sub, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Company Board equal to at least that number
of directors, rounded up to the next whole number, which is the product of (a)
the total number of directors on the Company Board (giving effect to the
directors elected pursuant to this sentence) multiplied by (b) the percentage
that (i) such number of shares of Company Common Stock so accepted for payment
and paid for by Sub plus the number of shares of Company Common Stock otherwise
owned by Sub or any other subsidiary of Parent bears to (ii) the number of such
shares outstanding, and the Company shall, at such time, cause Sub's designees
to be so elected; PROVIDED that in the event that Sub's designees are appointed
or elected to the Company Board, until the Effective Time the Company Board
shall have at least two directors who are Directors on the date of this
Agreement and who are not officers of the Company (the "INDEPENDENT DIRECTORS");
and PROVIDED FURTHER that in such event, if the number of Independent Directors
shall be reduced below two for any reason whatsoever, the remaining Independent
Director shall be entitled to designate a person to fill such vacancy who shall
be deemed to be an Independent Director for purposes of this Agreement or, if no
Independent Directors then remain, the other directors shall designate two
persons to fill such vacancies who are not current or former officers,
shareholders or affiliates of the Company, Parent or Sub, and such persons shall
be deemed to be Independent Directors for purposes of this Agreement. Subject to
applicable Law, the Company shall take all action requested by Parent necessary
to effect any such election, including mailing to its shareholders the
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company shall
make such mailing with the mailing of the Schedule 14D-9 (PROVIDED that Sub
shall have provided to the Company on a timely basis all information required to

         Law, the Company shall have obtained the Company
         Shareholder Approval.

         and CFIUS shall not have taken any action or made any recommendation to
         the President of the United States to block or prevent the consummation

         any foreign antitrust Law, the absence of which would prohibit the
         consummation of the Merger, shall have been obtained or made.

                           (c) NO INJUNCTIONS OR RESTRAINTS. No temporary

                  Agreement or (y) to any party whose failure to fulfill any of
                  its obligations under the Transaction Agreements results in
                  the failure of any Tender Offer Condition or if the failure of
                  such condition results from facts or circumstances that
                  constitute a breach of any representation or warranty of such
                  party contained in any Transaction Agreement; or

                                    (iii) if, upon a vote at a duly held meeting

         perform in any material respect any of its representations, warranties

         Condition and (ii) cannot be or has not been cured within 30 days after
         the giving of written notice to the Company of such breach;

                           (d) by Parent or Sub if either Parent or Sub is
         entitled to terminate the Offer as a result of the occurrence of any
         event set forth in paragraph (d) of Exhibit A to this Agreement; or

waiver shall be valid only if set forth in an instrument in writing signed on

of its rights under this Agreement or otherwise shall not constitute a waiver of
such rights.

                  SECTION 8.05. PROCEDURE FOR TERMINATION, AMEND MENT, EXTENSION
OR WAIVER. Except as otherwise provided in Section 6.09 hereof, termination of

                  SECTION 9.03.  DEFINITIONS.  For purposes of this
Agreement:

                  An "AFFILIATE" of any person means another person that
directly or indirectly, through one or more intermediaries, controls, is
controlled by, or is under common control with, such first person.

                  "IN THE ORDINARY COURSE OF BUSINESS", with respect to any
action, means such action is:

                  (a) consistent with the past practices of such person and is
         taken in the ordinary course of the normal day-to-day operations of
         such person;

                  (b) not required to be authorized by the Board of Directors of
         such person; and

                  (c) similar in nature and magnitude to actions customarily
         taken, without any authorization by the Board of Directors, in the
         ordinary course of the normal day-to-day operations of other persons
         that are in the same line of business as such person.

                  SECTION 9.04. INTERPRETATION; DISCLOSURE LETTERS. When a
reference is made in this Agreement to a Section, such reference shall be to a
Section of this Agreement unless otherwise indicated. The table of contents and
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement. Whenever
the words "INCLUDE", "INCLUDES" or "INCLUDING" are used in this Agreement, they
shall be deemed to be followed by the words "WITHOUT LIMITATION". Any matter
disclosed in any section of the Company Disclosure Letter shall be deemed
disclosed only for the purposes of the specific Section of this Agreement to
which such section


<PAGE>

                                                                          64

of the Company Disclosure Letter, such item may be fully described in the
principal section to which such item relates and incorporated into another
section by a specific cross reference in such other section to the section in
which such item is fully described. Nothing in the Company Disclosure Letter
shall be deemed adequate to disclose an exception to a representation or
warranty made herein unless the Company Disclosure Letter identifies the
exception with reasonable particularity. Without limiting the generality of the
foregoing, the mere listing (or inclusion of a copy) of a document or other item
shall not be deemed adequate to disclose an exception to a representation or
warranty made herein (unless the representation or warranty concerns the
existence of the document or other item itself or the copy adequately describes
the matter at issue).

                  SECTION 9.05. SEVERABILITY. If any term or other provision of
this Agreement is invalid, illegal or incapable of being enforced by any rule or
Law, or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the Transactions is not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that the Transactions are fulfilled to the extent possible.

                  SECTION 9.06. COUNTERPARTS. This Agreement may be executed in
one or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when one or more counterparts have been
signed by each of the parties and delivered to the other parties.

                  SECTION 9.07. ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES.
This Agreement, taken together with the Company Disclosure Letter, (a)
constitutes the entire agreement, and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
Transactions and (b) except for the provisions of Article II, and Section 6.05,
is not intended to confer upon any person other than the parties any rights or
remedies.

                  SECTION 9.08. GOVERNING LAW. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of New York,
regardless of the laws that might otherwise govern under applicable principles
of conflicts of laws thereof, except to the extent the laws of Texas are
mandatorily applicable to the Merger and to the rights of dissenting Company
shareholders, if any.

                  SECTION 9.09. ASSIGNMENT. Neither this Agreement nor any of
the rights, interests or obligations under this Agreement shall be assigned, in
whole or in part, by opera tion of law or otherwise by any of the parties
without the prior written consent of the other parties, except that (i) Sub may
assign, in its sole discretion, any of or all its rights, interests and
obligations under this Agreement to Parent or any assignee of Parent pursuant to
clause (ii) of this sentence, or to any direct or indirect wholly owned
subsidiary of Parent or such assignee, but no such assignment shall relieve Sub
of any of its obligations under this Agreement and (ii) Parent may assign, upon
notice to the Company prior to or immediately following such assignment, its
rights and obligations hereunder to any of its corporate affiliates, but no such
assignment shall relieve Parent of its obligations hereunder if its assignee
does not perform such obligations. Any purported assignment without such consent
shall be void. Subject to the preceding sentences, this Agreement will be
binding upon, inure to the benefit of, and be enforceable by, the parties and
their respective successors and assigns.

                  SECTION 9.10. ENFORCEMENT. The parties agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with its specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions of any Transaction Agreement in any New
York state court or any Federal court located in the State of New York, this
being in addition to any other remedy to which they are entitled at law or in
equity. In addition, each of the parties hereto (a) consents to submit itself to
the personal jurisdiction of any New York state court or any Federal court
located in the State of New York in the event any dispute arises out of this
Agreement or any Transaction, (b) agrees that it will not attempt to deny or
defeat such personal jurisdiction by motion or other request for

leave from any such court, (c) agrees that it will not bring any action relating

         circumstances upon which a vote, consent or other approval (including
         by written consent) with respect to the Merger Agreement, this

         granting the Company Shareholder Approval or the approval of this
         Agreement, the Offer, the Merger or any other Transaction and (ii)

         Agreement and the Merger), consolidation, combination, sale of
         substantial assets, reorganization, recapitalization, dissolution,
         liquidation or winding up of or by the Company, (B) any Company
         Takeover Proposal and (C) any amendment of the Company Charter or the
         Company By-laws or other proposal or transaction involving the Company
         or any Company Subsidiary, which amendment or other proposal or
         transaction would in any manner impede, frustrate, prevent, delay or
         nullify any provision of the Merger Agreement or this Agreement, the
         Offer, the Merger or any other Transaction or change in any manner the
         voting rights of any class of Company capital stock. The Shareholder
         understands and acknowledges that Parent is entering into the Merger
         Agreement in reliance upon the Shareholder's execution and delivery of
         this Agreement. The Shareholder hereby affirms that the irrevocable
         proxy set forth in this Section 3(a) is given in connection with the
         agreement of Parent to purchase the Subject Shares of the Shareholder,
         and the agreement of the Shareholder to vote the Subject Shares of the
         Shareholder, pursuant to this Agreement. The Shareholder hereby further
         affirms that the irrevocable proxy is coupled with an interest and may
         under no circumstances be revoked, except as otherwise provided in this
         Agreement. The Shareholder hereby ratifies and confirms all that such
         irrevocable proxy may lawfully do or cause to be done by virtue hereof.
         Such irrevocable proxy is executed and intended to be irrevocable prior
         to the Termination Date in accordance with the provisions of Article
         2.29.C of the TBCA. The irrevocable proxy granted hereunder shall
         automatically terminate upon the termination of this Agreement.

                  (b) At any meeting of shareholders of the Company or at any
         adjournment thereof or in any other circumstances upon which the
         Shareholder's vote, consent or other approval is sought, the
         Shareholder shall vote (or cause to be voted) the Subject Shares of the
         Shareholder in the manner specified in Section 3(a)(2). The Shareholder
         shall not commit or agree to take any action inconsistent with the

         whether by proxy, voting agreement or otherwise, with respect to any
         Subject Shares and shall not commit or agree to take any of the
         foregoing actions.

                  (d) The Shareholder shall not, nor shall it authorize or
         permit any officer, director or employee of, or any investment banker,
         attorney or other adviser or representative of, the Shareholder to, (i)
         directly or indirectly solicit, initiate or encourage the submission of
         any Company Takeover Proposal, (ii) enter into any agreement with
         respect to any Company Takeover Proposal or (iii) directly or

         other action to facilitate any inquiries or the making of any proposal
         that constitutes, or may reasonably be expected to lead to, any Company
         Takeover Proposal; PROVIDED, HOWEVER, that the Shareholder may furnish
         information with respect to the Company to a person and participate in

         actually furnishing information to and engaging in discussions or
         negotiations with, such person regarding such Superior Company Proposal

         Shareholder promptly shall advise Parent orally and in writing of any
         Company Takeover Proposal or inquiry made to the Shareholder with
         respect to or that could reasonably be expected to lead to any Company
         Takeover Proposal (including any change to the terms of any such
         Company Takeover Proposal or inquiry), the identity of the person
         making any such Company Takeover Proposal or inquiry, and the material
         terms of any such Company Takeover Proposal or inquiry.

                  (e) The Shareholder shall use all reasonable efforts to take,
         or cause to be taken, all actions, and to do, or cause to be done, and
         to assist and cooperate with the other parties in doing, all things
         necessary, proper or advisable to consummate and make effective, in the
         most expeditious manner practicable, the Offer, the Merger and the
         other Transactions, provided that in doing so the Shareholder shall not
         be required to relinquish any right or benefit that the Shareholder may
         have under any written employment agreement with the Company or any
         Company Subsidiary that has been filed as an exhibit to the Filed
         Company SEC Documents. The Shareholder shall not issue any press
         release or make any other public statement with respect to any
         Transaction Agreement, the Merger or any other Transaction without the
         prior consent of Parent, except as may be required by applicable Law.

                  SECTION 4. OPTION. (a) Each Shareholder hereby severally
grants to Parent an irrevocable option (the "OPTION") to purchase any of or all
the Subject Shares of such Shareholder that have not been validly tendered prior
to the expiration of the Offer, or that have been withdrawn prior to the
expiration of the Offer, at a purchase price per share equal to the Offer Price
in cash. The Option shall become exercisable, in whole or in part, only when the
Offer has expired and Sub has accepted shares of Company Common Stock for
purchase pursuant to the Offer. If the Option becomes exercisable, the Option
may be exercised by giving the notice referred to in Section 4(b) any time
during the period commencing with the acceptance by Sub of shares of Company
Common Stock for purchase pursuant to the Offer and ending 30 days thereafter
(the "OPTION PERIOD"); PROVIDED, HOWEVER, that if, on the expiration of the
Option Period, (i) any waiting period under the HSR Act applicable to the
purchase of shares of Company Common Stock pursuant to the Option shall not have
expired or been terminated, (ii) the period of time for any

                                                                               8


applicable review process by CFIUS under the Exon-Florio Act shall not have
expired or (iii) there shall be in effect any preliminary or permanent
injunction or other order issued by any Governmental Entity prohibiting the
exercise of the Option pursuant to this Agreement, then the Option Period shall
be extended until five business days after the later of the date of expiration
or termination of any applicable waiting period under the HSR Act, the
expiration of the period of time for any applicable review process under the
Exon-Florio Act, and the date of removal or lifting of any such injunction or
order.

                  (b) If Parent wishes to exercise the Option, it may do so by
giving written notice (the date of such notice being herein called the "NOTICE
DATE") to each Shareholder specifying that the Subject Shares are to be
purchased and specifying the place, time and date (which shall not be earlier
than one trading day, nor later than 10 trading days, from the Notice Date) for
the closing of the Purchase by Parent pursuant to such exercise.

                  SECTION 5. TERMINATION. Notwithstanding any other provision
contained herein, this Agreement and all rights and obligations of the parties
hereunder shall terminate upon the Termination Date, other than with respect to
the liability of any party for breach hereof prior to such termination. As used
herein, the term "TERMINATION DATE" shall mean the earlier to occur of (i) the
Effective Time and (ii) the termination of the Merger Agreement in accordance
with its terms.

                  SECTION 6. ADDITIONAL MATTERS. (a) Each Shareholder shall,
from time to time, execute and deliver, or cause to be executed and delivered,
such additional or further consents, documents and other instruments as Parent
may reasonably request for the purpose of effectively carrying out the
transactions contemplated by this Agreement.

                  (b) No person executing this Agreement who is or becomes
during the term hereof a director or officer of the Company makes any agreement
or understanding herein in his or her capacity as a director or officer of the
Company. Each Shareholder signs solely in such Shareholder's capacity as the
record holder and beneficial owner of, or the trustee of a trust whose
beneficiaries are the beneficial owners of, such Shareholder's Subject Shares
and nothing herein shall limit or affect any actions taken by any Shareholder in
his capacity as an officer, director or affiliate of the

                                                                               9


Company to the extent specifically permitted by the Merger Agreement.

                  SECTION 7.  GENERAL PROVISIONS.  (a)  AMENDMENTS.  This
Agreement may not be amended except by an instrument in writing signed by each
of the parties hereto.

                  (b) NOTICE. All notices and other communications hereunder
shall be in writing and shall be deemed given if delivered personally or sent by
overnight courier (providing proof of delivery) to Parent in accordance with
Section 9.02 of the Merger Agreement and to the Shareholders at their respective
addresses set forth in Schedule A hereto (or at such other address for a party
as shall be specified by like notice).

                  (c) INTERPRETATION. When a reference is made in this Agreement
to Sections, such reference shall be to a Section to this Agreement unless
otherwise indicated. The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement. Wherever the words "INCLUDE", "INCLUDES" and "INCLUDING" are
used in this Agreement, they shall be deemed to be followed by the words
"WITHOUT LIMITATION".

                  (d) SEVERABILITY. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule or Law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the extent
possible.

                  (e) COUNTERPARTS. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement.
This Agreement shall become effective between Parent and any Shareholder when a
counterpart has been signed by Parent and delivered to such Shareholder and a
counterpart has been executed by such Shareholder and delivered to Parent. Each
party need not sign the same counterpart.

                  (f) ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES. This
Agreement (i) constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof and (ii) is not intended to confer upon any
person other than the parties hereto any rights or remedies hereunder.

                  (g) GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York, regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof, except to the extent the laws of Texas are mandatorily applicable
to Section 3.

                  (h) ASSIGNMENT. Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise, by Parent without the prior written
consent of each Shareholder or by any Shareholder without the prior written
consent of Parent, and any purported assignment without such consent shall be
void; PROVIDED, HOWEVER, that Parent may assign, upon notice to the Company
prior to or immediately following such assignment, its rights and obligations
hereunder to any of its corporate affiliates, but no such assignment shall
relieve Parent of its obligations hereunder if its assignee does not perform
such obligations. Subject to the preceding sentences, this Agreement will be
binding upon, inure to the benefit of, and be enforceable by, the parties and
their respective successors and assigns.

                  (i) ENFORCEMENT. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any New York state court or any
Federal court located in the State of New York, this being in addition to any
other remedy to which they are entitled at law or in equity. In addition, each
of the parties hereto (i) consents to submit itself to the personal jurisdiction
of any New York state court or any Federal court located in the State of New
York in the event any dispute arises out of this Agreement or any Transaction,
(ii) agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, (iii)
agrees that it will not

bring any action relating to this Agreement or any Transaction in any court
other than a New York state court or any Federal court sitting in the State of
New York and (iv) waives any right to trial by jury with respect to any claim or

                           CONFIDENTIALITY AGREEMENT

      THIS CONFIDENTIALITY AGREEMENT ("Agreement") is made and entered into on
this the 28th day of September, 1999, by and between TRIPOINT GLOBAL
COMMUNICATIONS INC., a Delaware corporation ("Recipient"), and VERTEX
COMMUNICATIONS CORPORATION, a Texas corporation ("Vertex").

                                  WITNESSETH:

      WHEREAS, Recipient and Vertex desire to enter into negotiations relating
to a possible business combination or acquisition (a "Transaction") involving
Recipient and Vertex;

      WHEREAS, in connection with Recipient's evaluation of the Transaction,
Recipient requires access to certain information of Vertex concerning the
business and affairs of Vertex that is either nonpublic, confidential or
proprietary in nature;

      WHEREAS, Vertex is willing to provide limited access to the Evaluation
Material (as hereinafter defined) to Recipient and Recipient's authorized
agents, subject to the restrictions hereinafter set forth pertaining to the
protection and preservation of the Evaluation Material, in order to enable
Recipient to determine whether Recipient desires to pursue further negotiations
with Vertex; and

      WHEREAS, the parties desire to set forth the terms and conditions upon
which the Evaluation Material is to be disclosed to Recipient and the rights and
obligations of the parties with respect to such Evaluation Material;

      NOW, THEREFORE, for and in consideration of the above stated premises, the
mutual covenants set forth herein, and other good and valuable consideration,
the recipient and sufficiency of which are hereby acknowledged, the parties
hereby agree as follows:

      1. Evaluation Material. As used herein, the term "Evaluation Material"
means all information that Vertex has furnished or is furnishing to Recipient
in connection with a Transaction, whether furnished before or after the date
of this Agreement, whether tangible or intangible, and whether verbally, in
writing, on computer disk or otherwise, including the customer list,
documents identifying past, present and future customers, the financial books
and records of Vertex and related financial statements and tax returns of
Vertex, and documents or other information pertaining to the assets,
liabilities and business operations of Vertex and its subsidiaries, as well
as all information generated by Recipient or by Recipient's Representatives
(as defined below) that contains, reflects, or is derived from the foregoing
furnished information, including all analyses, compilations, data, studies,
notes, interpretations, memoranda or other

                                     - 1 -
<PAGE>

documents prepared by Recipient or Recipient's Representatives. Notwithstanding
the preceding, the term "Evaluation Material" shall not be construed to include,
and the confidentiality and use provisions of this Agreement shall not apply to:
(a) information that is or becomes generally available to the public other than
as a result of disclosure by Recipient or any of Recipient's Representatives,
(b) information known to Recipient prior to the time of disclosure by Vertex;
and (c) information that is obtained by Recipient from any other source than
Vertex or its affiliates, but only if such disclosure of information to
Recipient does not, to Recipient's knowledge, violate any contractual or legal
obligation to Vertex on the part of such source or does not, to Recipient's
knowledge, breach a confidential relationship of such source to Vertex.

      2. Confidentiality of Evaluation Material. The Evaluation Material is
disclosed and delivered to Recipient in the strictest confidence and Recipient
agrees to receive and hold the Evaluation Material in the strictest confidence
and in accordance with the provisions and intentions of this Agreement. This
Agreement shall apply to all of the Evaluation Material disclosed to Recipient
by Vertex or its agents, without regard to whether such disclosure is by means
of written documents or otherwise. Recipient acknowledges that the Evaluation
Material is proprietary to Vertex and that Recipient has no rights or interest
in the Evaluation Material and shall not use any part of the Evaluation Material
for Recipient's own benefit except as specifically set forth in this Agreement.

      3. Terms of Disclosure. Initially, the Evaluation Material shall be
disclosed by Vertex to Recipient for the sole purpose of evaluating the
feasibility of Recipient negotiating and executing an agreement with Vertex or
its shareholders to acquire, directly or indirectly, the assets or outstanding
shares of capital stock of Vertex or otherwise enter into a Transaction with
Vertex. Subject to the terms of this Agreement, Recipient may distribute or
otherwise disclose the Evaluation Material to a reasonable number of persons,
including Recipient's directors, officers, employees, lenders, prospective
lenders, attorneys, financial advisors, accountants and other experts
(collectively, "Recipient's Representatives"), on a need to know basis required
to enable Recipient to evaluate the Evaluation Material and the business of
Vertex in order to permit Recipient to determine whether and on what terms
Recipient desires to enter into a Transaction with Vertex (the "Permitted Use"),
provided such individuals are informed by Recipient of the confidential nature
of the Evaluation Material. Notwithstanding the preceding, Recipient
acknowledges and agrees that the sales or production personnel of Recipient
shall not be permitted access to the Evaluation Material without the prior
written consent of Vertex. In addition, Recipient agrees that it will not use
any part of the Evaluation Material for the purposes of marketing or product
development.

      4. Restriction of Further Disclosure. Recipient shall notify Vertex in
advance in writing of any individual other than Recipient's Representatives to
whom Recipient desires to disclose any part of the Evaluation Material. If
Vertex notifies Recipient that Vertex objects to


                                     - 2 -
<PAGE>

the dissemination of the Evaluation Material to such other individual, Recipient
shall not disseminate any part of the Evaluation Material to such other
individual. Neither party shall, without the prior written consent of the other
party, subject only to the exceptions expressly set forth in this Agreement: (a)
disclose to any third party the fact that Vertex has provided any of the
Evaluation Material to Recipient; (b) disclose to any third party that any
investigations, discussions or negotiations are taking place concerning a
Transaction involving Vertex and Recipient; or (c) disclose any of the terms,
conditions, status or other facts with respect to any such Transaction.
Notwithstanding anything to the contrary contained herein, each party may issue
any press release or make any public statement without approval of the other
party as may be required by law, provided the party issuing the press release or
making such statement shall give prior notice thereof to the other party and
consult with the other party as to the contents thereof. Recipient shall not,
without the prior written consent of Vertex, subject only to the exceptions
expressly set forth in this Agreement, (a) disclose to any third party any or
all of the Evaluation Material; (b) permit any third party to have access to the
Evaluation Material; or (c) use the Evaluation Material for any purpose other
than the Permitted Use.

      5. Protection of Information. Recipient shall use commercially reasonable
efforts, including efforts commensurate with those used by Recipient for the
protection of its own confidential and proprietary information, to protect the
Evaluation Material disclosed to Recipient and Recipient's agents pursuant to
this Agreement; provided, however, Recipient shall have no obligation or
authority to initiate litigation or incur costs or other expenses on behalf of,
or for the benefit of, Vertex. Recipient shall be responsible to Vertex for all
authorized and unauthorized disclosures of the Evaluation Material by Recipient
or Recipient's Representatives or agents. Such responsibility of Recipient shall
be in addition to and not by way of limitation of any right or remedy Vertex
may have against Recipient's Representatives with respect to any such breach.

      6. Compelled Disclosure. Recipient agrees that in the event that it or any
of Recipient's Representatives are requested or required (by law, deposition,
interrogatory, request for documents, subpoena, civil investigative demand or
similar process) to disclose any of the Evaluation Material, Recipient will
provide Vertex with prompt prior written notice of such request or requirement
so that Vertex may seek a protective order or other appropriate remedy and/or
consent in writing to such disclosure. In the event that such protective order
or other remedy is not obtained and Vertex has not consented in writing to such
disclosure, and Recipient or Recipient's Representatives are nonetheless,
advised in writing by Recipient's outside legal counsel, that they are legally
required to disclose the Evaluation Material, Recipient and Recipient's
Representatives may furnish only that portion of the Evaluation Material that
Recipient and Recipient's Representatives are advised in writing by outside
legal counsel is legally required; provided that Recipient will exercise
commercially reasonable efforts to assist Vertex in obtaining an order or
reasonable assurance that the confidential treatment will be


                                      -3-
<PAGE>

accorded such Evaluation Material.

      7. Return of Evaluation Material. In the event that Vertex requests in
writing the return of the Evaluation Material, Recipient shall deliver to the
President of Vertex all of the Evaluation Material theretofore disclosed to
Recipient in the form of documents and tangible items, and all copies,
summaries, records, and descriptions thereof and all other written information
which constitutes Evaluation Material, including all such written information in
the possession of Recipient's Representatives and agents. Notwithstanding the
preceding, that portion of the Evaluation Material that was generated by
Recipient or Recipient's Representatives may be destroyed by Recipient or
Recipient's Representatives (rather than being returned to Vertex); provided,
however, that Recipient shall promptly deliver to Vertex a certificate signed by
the President of Recipient certifying that such Evaluation Material has been
destroyed. Notwithstanding the return or destruction of the Evaluation Material
in accordance with this Section, Recipient and Recipient's Representations shall
continue to be bound by the other provisions of this Agreement.

      8. No Representation as to Completeness. Each of Vertex and Recipient
acknowledges that neither Vertex nor any of its representatives makes any
express or implied representation or warranty as to the accuracy or completeness
of the Evaluation Material and that each of Vertex and its representatives
expressly disclaims any and all liability that may be based on the Evaluation
Material, errors therein, or omissions therefrom. Recipient acknowledges (i)
that Recipient is not entitled to rely on the accuracy or completeness of the
Evaluation Material, (ii) that neither Vertex nor any of its representatives
shall have any liability whatsoever to Recipient or any other entity based on
the Evaluation Material, and (iii) that Recipient instead shall be entitled to
rely solely on the representations and warranties, if any, made to Recipient in
any definitive agreement regarding the Transaction (a "Definitive Agreement").
The term "Definitive Agreement" does not include an executed letter of intent or
any other preliminary written agreement that the parties thereto state is not
intended to be legally binding, except in accordance with the terms of any such
letter of intent or other preliminary written agreement. In addition, a
Definitive Agreement does not include any written or oral acceptance of any
offer or bid submitted by Recipient or Vertex.

      9. No Obligation. Each of Vertex and Recipient understands and agrees that
no contract or agreement providing for a Transaction shall be deemed to exist
until a Definitive Agreement has been executed and delivered, and each of Vertex
and Recipient hereby waives, in advance, any claims (including breach of
contract) in connection with a Transaction unless and until Recipient and Vertex
shall have entered into a Definitive Agreement. Each of Vertex and Recipient
also agrees that unless and until a Definitive Agreement between Recipient and
Vertex with respect to a Transaction has been executed and delivered, neither
Vertex nor Recipient nor any of their respective shareholders or affiliates have
any legal obligation of any kind whatsoever with respect to such Transaction by
virtue of this Agreement or any other written or oral


                                      -4-
<PAGE>

expression with respect to such Transaction except, in the case of this
Agreement, for the matters specifically agreed to herein. Recipient understands
that (i) Vertex and its financial advisors shall be free to conduct any process
for any Transaction as they in their sole discretion shall determine (including
negotiating with any of the prospective parties to such Transaction and entering
into a Definitive Agreement without prior notice to Recipient or any other
person) and (ii) any procedures relating so such Transaction may be changed at
any time without notice to Recipient or any other person.

      10. Right to Terminate Negotiations. Each of Vertex and Recipient reserves
the right, in such party's sole discretion, to reject any and all proposals made
regarding a Transaction and to terminate negotiations and discussions with the
other party at any time.

      11. Securities Laws. Recipient acknowledges that (i) Recipient is aware
that, under certain circumstances, the United States securities laws prohibit a
person who has material, nonpublic information about a company from purchasing
or selling securities of that company, or from communicating that information to
any other person under circumstances in which it is reasonably foreseeable that
such person is likely to purchase or sell those securities and (ii) Recipient is
familiar with the Securities Exchange Act of 1934 (the "Exchange Act") and the
rules and regulations promulgated thereunder, and agrees that Recipient will
neither use, nor cause any third party to use, any Evaluation Material in
contravention of the Exchange Act or any such rules and regulations, including
Rules 10b-5 and 14e-3.

      12. Standstill. Recipient agrees that, prior to one year after the date
hereof, Recipient will not (and will ensure that its affiliates that control,
are controlled by or are under common control with it (as defined in the rules
under the Exchange Act) and any person acting on behalf of or in concert with
Recipient or any controlled affiliate will not), alone or with others, directly
or indirectly, take any of the following actions unless Recipient is first
invited in writing by the Board of Directors of Vertex to make such action:

            a. Purchase or otherwise acquire (or enter into any agreement or
      make any proposal to purchase or otherwise acquire) record or beneficial
      ownership of any securities (which, for purposes of this Agreement,
      includes, without limitation, indebtedness) of Vertex, any warrant or
      option to purchase such securities, any security convertible into or
      exchangeable for any such securities or any other right to acquire such
      securities;

            b. Propose to Vertex or its security holders, or make any
      announcement with respect to, any Transaction between Recipient, any of
      its affiliates or Recipient and any other person, on the one hand, and
      Vertex or any of its security holders, on the other hand, or involving
      Vertex or any of its securities or security holders;

                                     - 5 -
<PAGE>

            c. Effect or seek, offer or propose (whether publicly or otherwise)
      to effect or participate in (i) any acquisition of the assets of Vertex or
      any of its subsidiaries, (ii) any tender or exchange offer, merger or
      other business combination involving Vertex or any of its subsidiaries, or
      (iii) any recapitalization, restructuring, liquidation, dissolution or
      other extraordinary transaction with respect to Vertex or any of its
      subsidiaries;

            d. Seek to control or influence Vertex, its management, Board of
      Directors (including without limitation by affecting the composition of
      the Board of Directors) or policies through the solicitation of proxies,
      consents, or otherwise or make or in any participate in any solicitation
      of proxies to vote, or seek to advise or influence any person with respect
      to the voting of securities of Vertex;

            e. Seek to advise or influence any person with respect to the voting
      of securities of Vertex;

            f. Assist, advise, encourage, or provide any information or
      financing to any other persons seeking to acquire, directly or indirectly,
      control of Vertex, its management, Board of Directors, policies,
      securities, business or assets;

            g. Make any request to waive, amend or terminate any provision of
      this Agreement or to permit Recipient to take any action prohibited
      herein; or

            h. Take any initiative with respect to Vertex or its subsidiaries
      which could require Vertex to make a public announcement regarding any
      such prohibited initiative or action referred to in this Section.

      Notwithstanding the foregoing, (i) if any third party that is not an
affiliate of Recipient publicly makes (x) a tender or exchange offer or other
bona fide offer (including an offer for a privately negotiated transaction) to
acquire directly or indirectly securities of Vertex under circumstances such
that, immediately after such acquisition, such third party would beneficially
own more than 15% of any class of such securities, or (y) a proposal or offer
for a merger, consolidation or other business combination directly or indirectly
involving Vertex or a proposal or offer to acquire directly or indirectly all or
substantially all of the assets of Vertex (any proposal or offer referred to in
clauses (x) or (y) being herein called a "Business Combination Proposal"), which
Business Combination Proposal is either (A) not withdrawn or terminated within
five days after such Business Combination Proposal is made or (B) accepted by
the Board of Directors of Vertex, the restrictions set forth in this Section
shall not be deemed to preclude Recipient from making a Business Combination
Proposal; provided that the restrictions set forth in this Section shall again
be applicable in accordance with their terms upon the withdrawal or termination
of the original Business Combination Proposal or the rejection thereof by the
Board of Directors of Vertex, except to the extent Recipient has previously
publicly announced a


                                     - 6 -
<PAGE>

Business Combination Proposal as permitted by this sentence.

      13. Remedies. Recipient acknowledges and agrees that, in the event of any
breach of this Agreement, Vertex would be irreparably and immediately harmed and
could not be made whole by monetary damages. Accordingly, Recipient agrees that,
in addition to any other remedy to which Vertex may be entitled at law or in
equity, Vertex shall be entitled to an injunction or injunctions (without the
posting of any bond or security and without proof of actual damages) to prevent
breaches of this Agreement and/or to compel specific performance of the
Agreement, and that neither Recipient nor Recipient's Representatives will
oppose the granting of such relief.

      14. Fees and Expenses. Except as otherwise provided herein or as may
otherwise be agreed upon by the parties in writing, the parties shall each pay
all of their own fees and expenses incident to the negotiation, preparation,
execution and performance of this Agreement and the transactions contemplated
hereby, including without limitation the fees and expenses of their respective
counsel, accountants, and other experts and representatives, whether or not the
transactions contemplated by this Agreement are consummated.

      15. Legal Fees and Costs. In the event any party must incur legal expenses
to enforce any provision of this Agreement, the prevailing party will be
entitled to recover such legal expenses, including without limitation,
attorneys' fees, costs and necessary disbursements, in addition to any other
relief to which such party shall be entitled.

      16. Vertex Representatives. All contacts by Recipient or Recipient's
Representatives with Vertex, regarding the Evaluation Material or a Transaction
shall be made through either J. Rex Vardeman, the President and Chief Executive
Officer of Vertex, or James D. Carter, the Vice President and Chief Financial
Officer of Vertex, or such other person as Recipient is notified in writing to
contact.

      17. Amendment. This Agreement may not be modified, altered, amended or
terminated except by the written agreement of all of the parties.

      18. Integrated Agreement. This Agreement sets forth the entire
understanding of the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous representations, understandings and
agreements, oral or written, made between the parties or their affiliates
concerning the subject matter hereof, and all such prior or contemporaneous
representations, understandings and agreements are hereby terminated.

      19. Waiver. No failure or delay by Vertex or Recipient in exercising any
right, power, or privilege hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power, or privilege
preclude any other or further exercise thereof.

      20. Invalid Provision. The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect. If
any of the provisions of this Agreement shall be deemed to be unenforceable by
reason of its extent, duration, scope or otherwise, then the parties contemplate
that the court making such determination shall enforce the remaining provisions
of this Agreement, shall reduce such extent, duration, scope or other provision
and shall enforce them in their reduced form for all purposes contemplated by
this Agreement.

      21. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas without regard to its rules
governing conflicts of law.

      22. Counterpart Execution. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute but one and the same instrument.

      23. Termination. This Agreement shall terminate on the third anniversary
of the date hereof.

      IN WITNESS WHEREOF, the parties have executed this Agreement effective as
of the day and year first above written.
