ITEM 1. SECURITY AND SUBJECT COMPANY.

    The name of the subject company is Vertex Communications Corporation, a
Texas corporation (the "Company"). The principal executive offices of the
Company are located at 2600 North Longview Street, Kilgore, Texas 75662-6842.
The class of equity securities to which this statement relates is the Common
Stock ("Common Stock") of the Company, par value $0.10 per share (the "Shares").

ITEM 2. TENDER OFFER OF THE BIDDER.

    This statement relates to the tender offer disclosed in the Schedule 14D-1,
dated November 18, 1999 (the "Schedule 14D-1"), of Signal Acquisition
Corporation, a Texas corporation (the "Purchaser") and a wholly owned subsidiary
of Tripoint Global Communications Inc., a Delaware corporation ("Parent"), to
purchase all of the outstanding Shares at a price per share of $22.00 (the
"Offer Price") net to the seller in cash, without interest thereon, upon the
terms and subject to the conditions set forth in the Offer to Purchase dated
November 18, 1999 (the "Offer to Purchase") and in the related Letter of
Transmittal (which, together with the Offer to Purchase and any amendments or
supplements to the Letter of Transmittal and the Offer to Purchase, constitute
the "Offer" and are contained in the Schedule 14D-1). According to the
Schedule 14D-1 the address of the principal executive offices of Parent and
Purchaser are each located at 565 Fifth Avenue, 17th Floor, New York, New York
10017.

    The Offer is being made pursuant to an 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 satisfaction or waiver, if permissible, of all
conditions to the Merger (as defined herein) 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
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 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 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 Purchaser reserves the right
(subject to the applicable rules and regulations of the Securities and Exchange
Commission ("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 (as defined below) to validly tender their
Shares prior to the expiration of the Offer, or from the withdrawal of any of
the Principal Shareholders' 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. A copy of the Merger Agreement is filed herewith as Exhibit 1 and
incorporated herein by reference.

                                       1
<PAGE>
    Simultaneously with entering into the Merger Agreement, Parent and the
Purchaser also 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
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 the 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).

ITEM 3. IDENTITY AND BACKGROUND.

    (a) The name and business address of the Company, which is the entity filing
this statement, are set forth in Item 1 above.

    (b)(1) Certain contracts, agreements, arrangements, or understandings
between the Company and its executive officers, directors or affiliates are
described in the Information Statement Pursuant to Section 14(f) of the
Securities Exchange Act of 1934 and Rule 14f-1 thereunder (the "Information
Statement") attached hereto as Annex I and incorporated herein by reference.

    (b)(2) Descriptions of (i) the Merger Agreement, (ii) the Shareholder
Agreement and (iii) the Confidentiality Agreement between Parent and the Company
dated as of September 28, 1999 are set forth below. Except as described or
referenced in this Item 3(b), there are no material contracts, agreements,
arrangements or understandings, or any potential or actual conflicts of interest
between the Company or its affiliates and the Company, Parent, the Purchaser or
any of their respective executive officers, directors or affiliates.

THE MERGER AGREEMENT.

    The Merger Agreement provides that following the satisfaction of the
conditions described below under "Conditions to Obligations of Each Party Under
the Merger Agreement," 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.

    VOTE REQUIRED TO APPROVE MERGER.  The Texas Business Corporation Act
("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 TBCA, 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, 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 the shareholders of the Company 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

                                       2
<PAGE>
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.

    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 closing date of the
Merger 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 (the "Company
Shareholder Approval"); (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 or Parent 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.

    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) the 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 of
the Offer to Purchase 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 such 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 to obtain the Company Shareholder Approval, such
approval is not

                                       3
<PAGE>
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 of the Offer to Purchase 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) under Section 14 of the Offer to Purchase; 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) 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.

    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 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 the non-solicitation provisions of the Merger Agreement, 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 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 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

                                       4
<PAGE>
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.

    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 Securities Exchange Act of
1934, as amended (the "Exchange Act"), or making any disclosure to the Company's
shareholders if, in the good faith judgment of the 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

                                       5
<PAGE>
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.

    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 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) referred to in Section 14 of the Offer to Purchase, 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.

    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
liabilities thereof.

                                       6
<PAGE>
    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
a direct or indirect wholly owned subsidiary of the Company to its parent,
(B) 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 or (C) purchase, redeem or
otherwise acquire any shares of capital stock of the Company or any subsidiary
of the Company or any other securities thereof or any rights, warrants or
options to acquire any such shares or other securities other than pursuant to
the provisions of the Merger Agreement relating to Company Stock Options and the
TIW Systems, Inc. Stock Bonus Plan; (ii) issue, deliver, sell, grant, pledge or
otherwise encumber or subject to any lien (A) any shares of its capital stock,
(B) any 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 the issuance of Shares upon the exercise of Company Stock
Options outstanding on the date of the Merger Agreement and in accordance with
their present terms; (iii) amend the Company's articles of incorporation, the

    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.

    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
cancellation of a Company Stock Option in exchange for the cash payment
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's 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.

                                       9
<PAGE>
    "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.

    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's articles of incorporation or the Company's 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 indemnification
provisions in the Merger Agreement 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.

    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) under
Section 14 of the Offer to Purchase. 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

                                       10
<PAGE>
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.

    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.

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

    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.

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

(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,

                                       11
<PAGE>
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 articles of incorporation 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
the 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
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.

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.

ITEM 4. THE SOLICITATION OR RECOMMENDATION.

    (a) Recommendation of the Board of Directors

    At a meeting of the Board of Directors held on November 11, 1999, the Board
unanimously approved the Shareholder Agreement and the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger.

    The Board of Directors unanimously adopted resolutions (i) recommending that
the Company's shareholders accept the Offer and tender their Shares pursuant to
the Offer, (ii) recommending that the Company's shareholders approve the Merger
Agreement and the Merger and (iii) determining that the Offer and the Merger are
fair to and in the best interests of the shareholders of the Company.

    A letter to the shareholders communicating the recommendation of the Board
and a joint press release announcing the Offer, the Merger and the Merger
Agreement are filed herewith as Exhibit 4 and Exhibit 5, respectively, and are
incorporated herein by reference.

    (b) Background of the Offer; Reasons for the Board of Directors'
Recommendations

BACKGROUND OF THE OFFER

    On January 8, 1997, Jack Haegele, 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 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, when 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 the price range for the
transaction.

    On September 23, 1999, the Company's Board met to consider whether
management should pursue discussions with Parent regarding the sale of the
Company. The Board authorized management to continue to explore, monitor and
report to the Board on strategic alternatives available to the Company,
including the possible acquisition of the Company by Parent. The Board also
authorized management to retain a qualified investment banking firm to advise
and assist the Board and management in a review of the Company's strategic
alternatives.

    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, and the Company's advisors to negotiate the terms of the Merger
Agreement and the Shareholder Agreement.

    On October 21, 1999, the Company's Board met to discuss the status of the
discussions and negotiations with Parent regarding a potential acquisition. The
Company and its counsel had received a preliminary draft of a merger agreement
from Parent's counsel. Counsel to the Company explained in detail the terms of
the preliminary draft merger agreement and answered questions regarding these
terms. Mr. Vardeman also advised the Board that the Company had engaged Frost
Securities, Inc. ("Frost Securities") as its financial advisor.

    On October 27, 1999, the Company's Board met to discuss the status of the
negotiations with Parent. The Board instructed management and the Company's
advisors to continue to negotiate the terms of a merger agreement with Parent
and to keep the Board currently appraised on an ongoing

                                       13
<PAGE>
basis of the status of such negotiations. Following the October 27th Board
meeting, extensive negotiations occurred concerning the terms of the Merger
Agreement and the Shareholder Agreement.

    On November 4, 1999, the Board met to discuss the proposed Merger. At this
meeting, 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 Company's Board 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 New York Stock Exchange opened for trading on the morning
of November 12, 1999.

REASONS FOR THE TRANSACTION; FACTORS CONSIDERED BY THE BOARD

    In approving the Offer and the Merger and recommending that all shareholders
tender their Shares pursuant to the Offer and approve and adopt the Merger
Agreement and the transactions contemplated by the Merger Agreement, the Board
considered a number of factors, including:

    (i) the financial and other terms and conditions of the Offer, the Merger
        and the Merger Agreement, including the $22.00 per Share consideration
        to be received by the Company's shareholders in the Offer and the
        Merger, as well as the fact that shareholders would receive a cash
        payment with no financing condition;

    (ii) the belief of the Board after considering the possible alternatives to
         the Offer and the Merger, that no other buyer would be likely to be
         willing to purchase all of the outstanding Shares at a price
         significantly above the $22.00 Offer Price;

   (iii) the historical market price performance of the Shares, the fact that
         the $22.00 per Share consideration represents: a premium of
         approximately 48.5% over the $14.81 closing sales price for the Shares
         on the New York Stock Exchange on November 11, 1999, the last trading
         day prior to the public announcement of the execution of the Merger
         Agreement; a premium of approximately 38.0% over the $15.94 closing
         sales price one week prior, on November 4, 1999; a premium of
         approximately 12.8% over the 52-week high of $19.50 per Share; a
         premium of approximately 46.5% over the 52-week average of $15.02 per
         Share; and a premium of approximately 96.6% over the 52-week low of
         $11.19 per Share;

    (iv) the presentation of Frost Securities at the meeting of the Board held
         November 4, 1999 and the opinion of Frost Securities dated
         November 11, 1999, to the effect that, as of such date and based upon
         and subject to certain matters stated in such opinion, the proposed
         $22.00 per Share consideration to be received by holders of Shares in
         the Offer and the Merger was fair, from a financial point of view, to
         such holders. The full text of the written opinion of Frost Securities,
         dated November 11, 1999, which sets forth assumptions made, matters
         considered and limitations on the review undertaken in connection with
         the opinion, is filed herewith as Exhibit 6 and is incorporated herein
         by reference. Shareholders are urged to read such opinion of Frost
         Securities in its entirety;

    (v) the fact that, in the event that the Board decided to accept a Superior
        Company Proposal of a third party, the Board may, subject to compliance
        with the terms of the Merger Agreement,

                                       14
<PAGE>
        terminate the Merger Agreement and pay Parent the Termination Fee of
        $3.84 million, plus out-of-pocket expenses not in excess of $640,000.
        The Board believed that such termination provision would not be a
        significant deterrent to a higher offer by a third party interested in
        acquiring the Company;

    (vi) the belief of the Board that the terms of the Merger Agreement would
         not unduly discourage third parties from making bona fide proposals
         subsequent to the execution of the Merger Agreement and the fact that
         if a third party were to make an unsolicited Superior Company Proposal,
         the Company, in the exercise of its fiduciary duties, could determine
         to provide information to and engage in negotiations with such third
         party;

   (vii) the financial condition, historical results of operations and business
         and strategic objectives of the Company, including the risks involved
         in achieving those objectives; and

  (viii) other historical information concerning the Company's business,
         prospects, financial performance and condition, operations, technology,
         management and competitive condition.

    The Board did not find it necessary or practical to assign relative weights
to the above factors or determine that any factor was determinative or of more
importance than other factors. Rather, the Board viewed its position and
recommendation as being based on the totality of the information presented to
and considered by it. In addition, it is possible that different members of the
Board assigned different weights to the various factors described above.

ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.

    The Company has retained Frost Securities to act as its financial advisor in
connection with the Offer and the Merger. The Company has agreed to pay Frost
Securities a fee of $150,000 for rendering its fairness opinion. Of such fee,
$50,000 was paid to Frost Securities at the time of its engagement, $50,000 was
paid at the time Frost Securities rendered its fairness opinion, and the balance
of $50,000 will be payable to Frost Securities upon consummation of the Offer
and the Merger. The Company also has agreed to reimburse Frost Securities for
travel and other reasonable out-of-pocket expenses, including the reasonable
fees and disbursements of its legal counsel, and to indemnify Frost Securities
and related parties against certain liabilities, including liabilities under the
federal securities laws, arising out of Frost Securities' engagement.

    In the ordinary course of business, Frost Securities may actively trade
securities of the Company for its own account and for the account of customers
and, accordingly, may at times hold a short or long position in such securities.

    Neither the Company nor any other persons acting on its behalf currently
intends to employ, retain or compensate any other person to make solicitations
or recommendations to shareholders on its behalf concerning the Offer, except
that solicitations or recommendations may be made by directors, officers or
employees of the Company for which services no additional compensation will be
paid.

ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.

    (a) To the best of the Company's knowledge, no transactions in Shares have
been effected during the past 60 days by the Company or by any executive
officer, director, affiliate or subsidiary of the Company.

    (b) Certain of the Company's officers and directors have entered into an
agreement with Parent and the Purchaser in which they have agreed to tender
their Shares promptly in the Offer as described in Item 3 hereof under the
heading "Shareholder Agreement." To the knowledge of the Company, its executive
officers, directors and affiliates presently intend to tender, pursuant to the
Offer, any Shares that are held of record or are beneficially owned by them.

                                       15
<PAGE>
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.

    (a) Except as set forth in this Schedule 14D-9, the Company is not engaged
in any negotiation in response to the Offer that relates to or would result in
(i) an extraordinary transaction, such as a merger or reorganization, involving
the Company or any subsidiary of the Company; (ii) a purchase, sale or transfer
of a material amount of assets by the Company or any subsidiary of the Company;
(iii) a tender offer for or other acquisition of securities by or of the
Company; or (iv) any material change in the present capitalization or dividend
policy of the Company.

    (b) Except as described in Items 3(b) or 4(b) above, there are no
transactions, Board resolutions, agreements in principle or signed contracts in
response to the Offer that relate to or would result in one or more of the
matters referred to in paragraph (a) of this Item 7.

ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED.

    (a) The Information Statement attached as Annex I hereto and incorporated
herein by reference is being furnished pursuant to Rule 14f-1 under the Exchange
Act in connection with the potential designation by Parent, pursuant to the
Merger Agreement, of certain persons to be appointed to the Board other than at
a meeting of shareholders, as described in Item 3.

    (b) 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.

                       BOARD OF DIRECTORS AND COMMITTEES

    The business affairs of the Company are managed under the direction of the
Board. The Board meets on a regularly scheduled basis during the fiscal year of
the Company to review significant developments affecting the Company and to act
on matters requiring Board approval. It also holds special meetings as required
from time to time when important matters arise requiring Board action between
scheduled meetings. The Board or its authorized committees met ten times and
acted by unanimous written consent four times during the 1999 fiscal year.
During fiscal year 1999, each incumbent director participated in at least 75% of
the aggregate of (i) the total number of meetings of the Board (held during the
period for which he was a director) and (ii) the total number of meetings of all
committees of the Board on which he served (during the period that he served).
For the Board as a whole, attendance was 100% during the 1999 fiscal year.

    The Board has established Audit, Compensation, and Outside Directors Stock
Option Committees to devote attention to specific subjects and to assist it in
the discharge of its responsibilities. The functions of these committees, their
current members and the number of meetings held during fiscal year 1999 are
described below.

    AUDIT COMMITTEE.  The Audit Committee recommends to the Board the
appointment of the firm selected to be independent public accountants for the
Company and monitors the performance and independence of such firm; reviews and
approves the scope of the annual audit and quarterly reviews and evaluates with
the independent public accountants the Company's annual audit and annual
consolidated financial statements; reviews with management the status and

and other employment benefits of executive officers and key employees of the
Company. The Compensation Committee also administers the Company's Stock Option
Plan for Key Employees, the 1995 Stock Compensation Plan for officers, directors
(other than non-employee directors), employees and advisors, Management
Incentive Compensation Plan for officers and key employees and Employee Profit
Sharing Bonus Plan for employees. The Compensation Committee is authorized,
among other powers, to determine from time to time the individuals to whom stock
options shall be granted, the number of shares to be covered by each option and
the time or times at which options shall be granted pursuant to the stock option
plans for officers and other employees.

    The Compensation Committee is comprised of J. Rex Vardeman (Chairman) and
Messrs. Womble and Heitzman. The Compensation Committee held two meetings and
acted by unanimous written consent three times during the 1999 fiscal year.

    STOCK OPTION COMMITTEE.  The Company's Outside Directors Stock Option Plan
(the "Outside Directors Plan") is administered by the Stock Option Committee of
the Board comprised of Messrs. Vardeman (Chairman), Carter and A. Don Branum,
each of whom is an executive officer and director of the Company and ineligible
to participate in such plan. The Outside Directors Plan defines "Outside
Directors" eligible to participate in such plan as those directors of the
Company who are not regular salaried employees of the Company or its
subsidiaries. The Outside Directors Plan expired on December 31, 1996, but
certain previously granted stock options remain validly issued and outstanding

*   The closing price for the Company's Common Stock as reported by the New York
    Stock Exchange on September 30, 1999, was $11.1875 per share. The indicated
    value is calculated on the basis of the difference between the option
    exercise price per share and $11.1875, multiplied by the number of shares of
    Common Stock underlying each option.

COMPENSATION OF DIRECTORS

    The Company has adopted a policy whereby all outside directors
(non-employees) receive directors' fees of $1,000 for each meeting of the Board
attended (exclusive of telephonic meetings) and for each meeting of a committee
of the Board attended (exclusive of committee meetings held on the same day as
Board meetings). No director who is an employee of the Company receives any fees
for services as a director or member of any committee of the Board. All
directors are reimbursed for reasonable travel and out-of-pocket expenses
incurred in connection with attendance at meetings of the Board or of committees
of the Board.

    In addition, the Company has adopted the Outside Directors Plan whereby
stock option grants have been made from time to time on an irregular basis to
reward director performance and to encourage those qualifying directors of the
Company who are not employees to participate in the Company's long-term success.
Pursuant to this plan, the Company has previously granted non-qualified stock
options in fiscal year 1993 to Messrs. Womble and Heitzman to purchase 5,000
shares of Common Stock each at the exercise price of $10 per share, in fiscal
year 1995 for an additional 5,000 shares of Common Stock each at an exercise
price of $12 per share, and in fiscal year 1998 for an additional 5,000 shares
of Common Stock each at an exercise price of $17 per share. To date,
Messrs. Heitzman and Womble have exercised their 1993 options of 5,000 shares
each, and Mr. Womble has also exercised his 1995 option of 5,000 shares.

    In fiscal year 1998, the Company also adopted the Non-Employee Directors
Stock Option Plan, whereby stock option grants may be made from time to time on
an irregular basis to reward director performance and to encourage those
qualifying directors to participate in the Company's success. Pursuant to this
plan, in fiscal year 1998 the Company granted non-qualified stock options to
Messrs. Womble, Heitzman, and Farmer in the amount of 5,000 shares, 5,000
shares, and 10,000 shares, respectively, at an exercise price of $25.00 per
share. During fiscal year 1999 these 1998 options were modified to amend the
exercise price to $16.4375 per share. In addition, in fiscal year 1999 the
Company granted non-qualified stock options to Messrs. Womble, Heitzman, and
Farmer in the amount of 5,000 shares, 4,000 shares, and 3,000 shares,
respectively, at an exercise price of $12.4375 per share. To date, none of these
options have been exercised.

EMPLOYMENT AGREEMENTS

    J. Rex Vardeman, A. Don Branum, and James D. Carter, in their capacities as
(i) Chairman of the Board, President and Chief Executive Officer, (ii) Senior
Vice President and Assistant Secretary, and (iii) Vice President and Chief
Financial Officer and Treasurer, respectively, have each executed

                                      I-9
<PAGE>
employment agreements with the Company. These employment agreements are each for
three-year terms which automatically renew on a daily basis.

    Among other provisions, these agreements provide that, in consideration for
remaining in the employ of the Company, each officer is entitled, subject to
certain conditions, to receive benefits in the event of termination of
employment under certain circumstances, including, among other reasons, a Change
of Control of the Company. If such an officer is terminated for a reason other
than (a) his death, disability or retirement, (b) for cause, or (c) his
voluntary termination other than for good reason, such officer would be entitled
to receive from the Company, except as otherwise indicated below, a lump-sum
severance payment equal to the sum of the following payments: (i) the officer's
full base salary through the effective date of his termination at the rate then
in effect, (ii) any authorized but unreimbursed business expenses and any
vacation benefits which have accrued but are unpaid or unused as of the
effective date of termination, (iii) any accrued but unpaid annual bonus
compensation to the effective date of termination, but without accelerating the
bonus payment date, (iv) an amount equal to three times the average aggregate
direct annual compensation (salary and bonus) of the officer for the five fiscal
years of the Company ended immediately prior to the effective date of his
termination, and (v) in the event such officer is subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code"), resulting from any "excess parachute payment" received by such officer
as described in Section 280G(b) of the Code, an amount sufficient to ensure that
after payment of such excise tax, plus interest or penalties thereon, if any, as
the result of such "excess parachute payment," such officer will retain free and
clear of all claims, taxes, and impositions an amount equal to such excise tax,
interest and penalties, if any, imposed upon the excess payment received. In the
event that any such officer receives a parachute payment as a result of
termination of employment, such officer would be deemed to receive an "excess
parachute payment" if it equals or exceeds 300% of the officer's "base amount,"
generally the average annual compensation received by such officer over the five
most recent tax years. The "excess parachute payment" is computed as that
portion of the "parachute payment" which exceeds the "base amount."

    In addition, Rein Luik and Louis E. Becker, each in his capacity as
President and Vice President, respectively, of TIW entered into an agreement
with TIW, effective as of June 11, 1997, which includes the same provisions for
a similar term as summarized above as related to his employment in such capacity
with TIW or its successors.

    Within one year following the consummation of the Offer, each of J. Rex
Vardeman, James D. Carter, A. Don Branum, Rein Luik, and Louis E. Becker will
have the right, in accordance with their respective employment agreements with
the Company or its subsidiary, as applicable, to discontinue his duties with the
Company or subsidiary, as applicable, and receive the compensation described
above.

    Certain key employees of the Company have executed proprietary information
protection agreements acknowledging that all their discoveries made while an
employee of the Company will be the property of the Company and that they will
not disclose trade secrets or other confidential information of the Company to
others.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

    GENERAL.  Pursuant to rules designed to enhance disclosure of executive
compensation policies, the Company is required to provide certain data and
information regarding compensation and benefits provided to its Chief Executive
Officer and four other most highly compensated officers. The disclosure
requirements for these executive officers include the use of tables and a report
explaining the rationale and considerations which resulted in fundamental
executive compensation decisions affecting these individuals. In response to
this requirement, the Compensation Committee submits the following report for
inclusion in this Information Statement. The data and information included in
the various

                                      I-10
<PAGE>
compensation tables appearing elsewhere in this Information Statement should be
read in conjunction with and are deemed to be a part of this report.

    NAMED EXECUTIVE OFFICERS.  This report includes disclosure of the required
compensation information for the Company's Named Executive Officers for 1999.

    COMPENSATION COMMITTEE.  Decisions on compensation of the Company's
executive officers are made by the three-member Compensation Committee comprised
of J. Rex Vardeman, Chairman, Bill R. Womble and Donald E. Heitzman, Sr.

    COMPENSATION POLICIES.  The Company's executive compensation policies, as
endorsed by the Board of Directors, are designed to:

    - Provide competitive levels of compensation which support a
      pay-for-performance policy that integrates pay with achievement of annual
      and long-term performance goals by the Company as a whole and its
      respective subsidiaries and divisions, rewards noteworthy corporate
      performance, and recognizes individual initiative and achievements;

    - Provide a comprehensive program which enhances opportunities to achieve
      strategic business initiatives and facilitates the recruitment, retention
      and motivation of talented executives whose abilities are critical to the
      long-term success and competitiveness of the Company; and

    - Reward executives for long-term strategic management which supports the
      Company's strategy of providing superior value to its shareholders.

    Target levels of overall compensation of the Named Executive Officers are
intended to be reasonably consistent with those paid to similarly situated
executives of other employers of comparable size in the Company's industry, but
are increasingly being weighted toward programs contingent upon the performance
by the Company or its respective subsidiaries or divisions, as applicable. As a
result of the increased emphasis on tying executive compensation to corporate
performance (either of the Company as a whole or its respective subsidiaries or
divisions, as appropriate), in any particular year the Company's executives may
be paid more or less than executives of the Company's competitors, depending
upon the Company's performance or the performance of its respective subsidiaries
or divisions, as applicable. The Compensation Committee also endorses the
concept that stock ownership by management and stock-based performance
compensation arrangements are beneficial in aligning the interests of management
and shareholders in the enhancement of shareholder value. Thus, the Compensation
Committee has increasingly utilized these elements in determining the Company's
compensation benefits for its executive officers.

    Compensation paid the Company's executive officers in 1999, as reflected in
the foregoing tables as to the Named Executive Officers, consisted of base
salary, annual bonus and the granting of stock options to certain of the Named
Executive Officers under the Company's 1995 Stock Plan (as hereinafter defined).

    RELATIONSHIP TO PERFORMANCE.  The Compensation Committee's emphasis on tying
pay to performance criteria is reflected in the cash compensation paid to the
Named Executive Officers for 1999, as a range from approximately 3.5% to
approximately 7.9% of the amounts paid to four of the Named Executive Officers
for 1999 (approximately 3.5% for the Chief Executive Officer) resulted from
performance-based compensation pursuant to the Company's Management Incentive
Compensation Plan (the "Management Incentive Plan") for annual cash incentive
bonuses of the Company as a whole, its subsidiaries (the "Subsidiaries") and its
divisions (the "Divisions"). The objective measures of performance that are
utilized under the Management Incentive Plan include targeted versus actual
annual net income after tax of the Company as a whole, and targeted versus
actual net pre-tax income for its respective Divisions and Subsidiaries, each
viewed separately. Subjective considerations are considered only in establishing
base salaries and, to a lesser degree, the criteria for establishing the

                                      I-11
<PAGE>
annual operating plan for the Company as a whole, its Divisions and its
Subsidiaries, respectively, from which annual cash bonuses are determined and in
determining the target annual bonus award of each participant pursuant to the
Management Incentive Plan of the Company, its Divisions and its Subsidiaries, as
applicable.

    ANNUAL SALARIES.  For 1999, the Compensation Committee established the
annual base salaries of the respective Named Executive Officers at levels based
on increases ranging from approximately 2.4% to 10.0% (approximately 10.0% for
the Chief Executive Officer), as compared to their annual base salaries
prevailing in 1998. These adjustments for 1999 were warranted as to each Named
Executive, including the Chief Executive Officer, based on enhanced duties and
responsibilities, competitive data, individual performance, initiative and
contribution to overall corporate performance, tenure and internal comparability
considerations. Additionally, for 1998 the Company experienced the most
successful year in its history, having achieved increases of approximately 41%
in sales, approximately 41% in net income, and approximately 29% in earnings per
share compared to the results of fiscal year 1997. Accordingly, consistent with
the Company's executive compensation policy of tying executive compensation to
performance, the 1999 base salaries of the Named Executive Officers were
increased as compared to 1998 salary levels.

    ANNUAL BONUSES.  The annual cash incentive bonuses payable under the
respective Management Incentive Plans to the Named Executive Officers reported
in the Summary Compensation Table are based primarily on objective criteria and
to a lesser extent on subjective standards. Objective criteria include actual
versus target annual net income after tax of the Company as a whole, and actual
versus target annual net pre-tax income of each of the Company's Divisions and
Subsidiaries, respectively. Subjective criteria encompass factors considered
(i) in promulgating the annual operating plan and (ii) in determining the target
bonus award for each eligible participant under the applicable Management
Incentive Plan based upon the above described standards utilized in determining
annual base salaries. Target annual net income, after tax or pre-tax, as
applicable, utilized for purposes of establishing target annual cash incentive
bonuses for the year is based on the annual operating plan for the Company, its
Divisions, and its Subsidiaries, developed by management and approved by the
Board of Directors as a whole. In October 1998, the full Board of Directors,
acting upon the recommendations and with the participation of management,
established the following: (i) the parameters of the 1999 annual operating plan,
including, among other information, the financial objectives of the Company, its
Divisions, and its Subsidiaries, for such year; (ii) the percentage of net
income after tax of the Company to be available as the aggregate annual bonus
fund under the Company's Management Incentive Plan for its eligible
participants, including certain of the Named Executive Officers, measured by the
degree of achievement of the Company's actual net income after tax for 1998, as
compared to the target net income after tax for such year pursuant to the annual
operating plan; (iii) the percentage of pre-tax income of its respective
Divisions to be available as the aggregate annual bonus fund under the
Management Incentive Plan applicable to each Division for its eligible
participants, including certain of the Named Executive Officers, measured by the
degree of achievement of each Division's actual pre-tax income for 1999, as
compared to its target pre-tax income for such year pursuant to the annual
operating plan; and (iv) the percentage of pre-tax income of its respective
Subsidiaries to be available as the aggregate annual bonus fund under the
Management Incentive Plan applicable to each Subsidiary for its eligible
participants, including two of the Named Executive Officers, measured by the
degree of achievement of each Subsidiary's actual pre-tax income for 1999, as
compared to its target pre-tax income for such year pursuant to the annual
operating plan.

    In October 1998, through application of the criteria described above, the
Compensation Committee determined the target annual bonus award of each eligible
participant under the Management Incentive Plan, including each Named Executive,
as a percentage share of the target annual bonus fund available under such
plans, respectively, for 1999. As a result of the performance of the Company as
a whole, its Divisions, and its Subsidiaries in 1999, the Compensation Committee

                                      I-12
<PAGE>
determined the actual 1999 cash bonus award for each Named Executive, including
the Chief Executive Officer, by applying the objective criteria described above,
which procedure was also uniformly applied in determining the actual 1999 cash
bonuses for all other officers of the Company (including its Divisions) and its
Subsidiaries. The Compensation Committee followed the same procedure in
October 1999 to determine target 2000 cash incentive bonus awards pursuant to
the Management Incentive Plan.

    STOCK OPTION GRANTS.  The Company has adopted two stock option plans
(collectively, the "Stock Plans") to provide long-term incentive compensation
for eligible participants: the Stock Option Plan for Key Employees (the "Key
Employee Plan") and the 1995 Stock Compensation Plan (the "1995 Stock Plan").
Generally, executive officers and other key employees of the Company (including
its Divisions) and its Subsidiaries are entitled to participate in these Stock
Plans. Stock option grants under the Stock Plans provide the right to purchase
shares of the Company's Common Stock at fair market value (the average of the
high and low trading prices) on the date of grant. Additionally, the 1995 Stock
Plan provides that optionees may be granted stock appreciation rights with
respect to shares of Common Stock covered by related options granted under such
plan, which permit optionees to be paid the appreciation on the related stock
option in lieu of exercising such option. Each stock option granted under the
Key Employee Plan or the 1995 Stock Plan is effectively exercisable based on an
incremental vesting schedule of 20% per annum over five years; and may have a
maximum term of seven years under the Key Employee Plan or ten years pursuant to
the 1995 Stock Plan. The Stock Plans are structured to encourage the retention
of shares purchased under the Stock Plans and provide long-term compensation
opportunities to participating executives and other key employees only to the
extent that shareholders of the Company have benefitted.

    In 1999, the Compensation Committee approved the grant of certain stock
options pursuant to the 1995 Stock Plan to the respective Named Executive
Officers indicated in the tables accompanying this report. Option grants have
been made from time to time on an infrequent basis under the Stock Plans to
reward executive performance and to encourage optionees to participate in the
Company's long-term success as measured by the value of the Company's Common
Stock. Factors considered in determining the amounts of options include
multiples of base salary (designed to create greater opportunities commensurate
with enhanced responsibilities), competitive data, managerial abilities, and
individual initiative and achievements.

    The 1999 annual compensation of J. Rex Vardeman, President and Chief
Executive Officer, as reflected in certain tables accompanying this report, was
based on the policies described above.

                                          Respectfully submitted,

                                          COMPENSATION COMMITTEE

NOTES:

    A. The lines represent monthly index levels derived from compounded daily
       returns that include all dividends.

    B.  The indices are reweighted daily, using the market capitalization on the
       previous trading day.

    C.  If the monthly interval, based on the fiscal year end, is not a trading
       day, the preceding trading day is used.

    D. The index level for each series was set to $100.00 on September 30, 1994.

    *   The comparison assumes (i) $100 was invested on September 30, 1994, in
       the Company's Common Stock and in each of the foregoing indices and
       (ii) that any dividends paid by companies included in the comparative
       indices were reinvested in additional shares of the same class of equity
       securities of such companies at the frequency with which dividends were
       paid during the applicable periods depicted.

    The stock performance information depicted in the preceding chart is not
necessarily indicative of future stock price performance. The chart shall not be
deemed to be incorporated by reference in any filing by the Company under the

                              CERTAIN TRANSACTIONS

    The Board of the Company has adopted a policy that transactions between the
Company, its officers, directors, principal shareholders, and affiliates be
conducted on terms at least as favorable to the Company as those which could be
obtained from independent parties.

    The Company has entered into certain indemnification agreements with each of
its directors and executive officers to provide the maximum indemnification
allowed pursuant to its articles of incorporation, bylaws and applicable law.

    Mr. Womble, a director of the Company, is a partner of Thompson & Knight
L.L.P., a Dallas, Texas law firm that has been retained by the Company as its
corporate counsel.

                            SECTION 16 REQUIREMENTS

    Section 16(a) of the Exchange Act requires the Company's directors and
officers, and persons who own more than 10% of a registered class of the
Company's equity securities, to file initial reports of ownership and reports of
changes in ownership with the SEC. Such persons are required by SEC regulation
promulgated pursuant to the Exchange Act to furnish the Company with copies of
all Section 16(a) report forms they file with the SEC.

    Based solely on its review of the copies of such report forms received by it
with respect to fiscal year 1999, or written representations from certain
reporting persons, the Company believes that all filing requirements applicable
to its directors, officers and persons who own more than 10% of a registered
class of the Company's equity securities have been timely complied with in
accordance with Section 16(a) of the Exchange Act.

to cause Sub to make a tender offer (as it may be amended from time to time as
permitted under this Agreement, the "OFFER") to purchase all the outstanding
shares of common stock, par value $.10 per share, of the Company (the "COMPANY
COMMON STOCK"), at a price per share of Company Common Stock of $22.00, net to

                  WHEREAS the respective Boards of Directors of Parent, Sub and
the Company have approved the merger (the "MERGER") of Sub into the Company on

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

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

Conditions have been satisfied. Subject to the terms and conditions hereof, the

to the holders of Company Common Stock. Each of the Company, Parent and Sub

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

the Transactions, Parent and Sub shall hold in confidence the information

                  SECTION 1.07. ARTICLES OF INCORPORATION AND BYLAWS. (a) 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

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


<PAGE>

                                                                              12


(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

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.

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

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


<PAGE>

                                                                              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,

                                                                              22

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,
"COMPANY BENEFIT PLANS"). Except as disclosed in the Filed Company SEC Documents
or in the Company Disclosure Letter, there are not any employment, consulting,
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
of the Company or any Company Subsidiary. The Company has made available to
Parent true, complete and correct copies of (i) each Company Benefit Plan and
Company Benefit Agreement (or, in the case of any unwritten Company Benefit Plan
or Company Benefit Agreement a description thereof), (ii) the most recent annual
report on Form 5500 filed with the Internal Revenue Service with respect to each
Company Benefit Plan (if any such report was required), (iii) the most recent
summary plan description for each Company Benefit Plan for which such summary
plan description is required and (iv) each trust agreement and group annuity
contract relating to any Company Benefit Plan.

                  (b) Except as disclosed in the Company Disclosure Letter, all
Company Pension Plans have received favorable determination letters from the
Internal Revenue Service with respect to "TRA" (as defined in Section 1 of Rev.
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,
of the Internal Revenue Code of 1986, as amended (the "CODE"), and no such
determination letter has been revoked nor, to the knowledge of the


<PAGE>

                                                                              23


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


<PAGE>

                                                                              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

                  (c) ADVICE OF CHANGES. The Company shall promptly advise
Parent orally and in writing of any change or event that has had or would

or the Company Subsidiaries.

                  SECTION 5.02. NO SOLICITATION. (a) The Company shall, and
shall 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
in Section 5.02(e)). The Company shall not, nor shall it authorize or permit any
Company Subsidiary to, nor shall it authorize or permit any officer, director or
employee of, or any investment banker, financial advisor, attorney, accountant

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,

                                                                           42


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
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 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
person making such Superior Company Proposal pursuant to a confidentiality
agreement not less restrictive of the other party than the Confidentiality
Agreement (as defined in Section 6.02) 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 Company Subsidiary, whether or not such person
is purporting to act on behalf of the Company or any Company Subsidiary or
otherwise, shall be deemed to be a breach of this Section 5.02(a) by the
Company.

committee thereof shall (i) withdraw or modify, or propose publicly to withdraw

by the Company Board or any such committee of the Transaction Agreements, the
Offer or the Merger, (ii) approve or cause the Company or any Company Subsidiary
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 (iii) 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
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,

                                                                          43

based on the advice of outside counsel, that the failure to do so
would violate its fiduciary obligations under applicable Law, the Company 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 Company 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.

                  (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
receipt or delivery thereof.

                  (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.

                  (e) For purposes of this Agreement:

                  "COMPANY TAKEOVER PROPOSAL" means any inquiry, proposal or
         offer for (i) a merger, consolidation, dissolution, recapitalization,
         liquidation or other
<PAGE>

         business combination involving the Company or any Company Subsidiary,
         (ii) 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 Company Subsidiary equal to or greater than 20% of
         the number of such shares outstanding before such acquisition or (iii)
         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 Company Subsidiary, in each case other
         than the Transactions or the Satcom Sale (the transactions referred to
         in clauses (i), (ii) and (iii) 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, (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'

                                                                             45

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

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.

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

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
be included in the


<PAGE>


                                                                           56


Information Statement with respect to Sub's designees). In connection with the
foregoing, the Company shall promptly, at the option of Sub, either increase the
size of the Company Board or obtain the resignation of such number of its
current directors as is necessary to enable Sub's designees to be elected or
appointed to the Company Board as provided above. Notwithstanding anything in
this Agreement to the contrary, in the event Sub's designees are elected to the
Company Board, after such election and prior to the Effective Time, (i) the
affirmative vote of a majority of the Independent Directors shall be required in
addition to any required approval by the full Company Board to (A) amend or
terminate this Agreement on behalf of the Company, (B) waive any of the
Company's rights, benefits or remedies under this Agreement or (C) extend the
time for performance of Sub's obligations hereunder and (ii) the Independent
Directors shall have the power, acting together, to exercise any right of the
Company under this 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 of Company Common Stock other than Parent, Sub and their
respective subsidiaries and affiliates.

                  SECTION 6.10. SHAREHOLDER LITIGATION. The Company shall give
Parent the opportunity to participate in the defense or settlement of any
shareholder litigation against the Company and its directors relating to any
Transaction and the Company shall not agree to any such settlement without
Parent's consent.

                  SECTION 6.11. COMPLIANCE OF SUB. Parent shall cause Sub to
comply with all of Sub's obligations under the Transaction Agreements. Parent
hereby guarantees the performance of Sub's obligations under the Transaction
Agreements.

to the satisfaction or waiver on or prior to the Closing Date of the following
conditions:

                                                                           58


                           (a)  SHAREHOLDER APPROVAL.  If required by
         Law, the Company shall have obtained the Company
         Shareholder Approval.

                           (b) ANTITRUST. 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 the Committee on Foreign Investment in the
         United States ("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. 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.

                           (c) NO INJUNCTIONS OR RESTRAINTS. 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; PROVIDED, HOWEVER, that prior to asserting this condition,
         subject to Section 6.03, the party asserting such 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.

                           (d) PURCHASE OF COMMON STOCK. Sub shall have

         perform in any material respect any of its representations, warranties

                  SECTION 9.03.  DEFINITIONS.  For purposes of this
Agreement:

                  An "AFFILIATE" of any person means another person that

                  "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

         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

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

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

                             CONDITIONS OF THE OFFER

                  Notwithstanding any other term of the Offer or this Agreement,
Sub 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 Sub's obligation to pay for or return tendered shares of Company

Company if, at any time on or after the date of this Agreement and before the

         adjournment thereof or in any other circumstances upon which the
         Shareholder's vote, consent or other approval is sought, the

         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

proceeding related to or arising out of this Agreement or any Transaction.

                           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

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

      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

- --------------------------------------------------------------------------------

                               November 18, 1999

To Our Shareholders:

    We are pleased to inform you that on November 11, 1999, Vertex
Communications Corporation (the "Company") entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Tripoint Global Communications Inc.
("Tripoint") pursuant to which Signal Acquisition Corporation, a wholly owned
subsidiary of Tripoint, today commenced a cash tender offer to purchase all of
the outstanding shares of the Company's common stock, par value $0.10 per share,
for a cash price of $22.00 per share. The offer is conditioned upon, among other
things, the tender of at least a majority of the shares outstanding on a fully
diluted basis. The Merger Agreement provides that following consummation of the
offer, Signal Acquisition Corporation will be merged with and into the Company
and any shares not purchased in the offer (other than those held by dissenting
shareholders or by the Company, Tripoint, or any subsidiary of the Company or
Tripoint) will be converted into the right to receive $22.00 per share in cash.

    Simultaneously with entering into the Merger Agreement, Tripoint entered
into a Company Shareholder Agreement (the "Shareholder Agreement") with certain
shareholders of the Company (collectively, the "Principal Shareholders"),
whereby each Principal Shareholder agreed to tender his shares of the Company's
common stock pursuant to the offer. The Principal Shareholders collectively own
approximately 13.1% of all outstanding shares of the Company's common stock
(assuming the exercise of all Company stock options held by the Principal
Shareholders).

    The Board of Directors of the Company has unanimously approved the Merger
Agreement, the Shareholder Agreement, 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
the Company's shareholders accept the offer and tender their shares pursuant to
the offer. In arriving at its recommendation, the Board of Directors considered
the factors described in the attached Schedule 14D-9, including the opinion of
the Company's financial advisor, Frost Securities, Inc., to the effect that the
consideration to be received pursuant to the Merger Agreement is fair to the
holders of the Company's common stock from a financial point of view. The full
text of the written opinion of Frost Securities which sets forth assumptions
made, matters considered and limitations on the review undertaken in connection
with the opinion is attached to the Schedule 14D-9 and should be read carefully
in its entirety.

    Accompanying this letter is the Tripoint Offer to Purchase, dated
November 18, 1999, together with related materials including a Letter of
Transmittal to be used for tendering your shares. These documents set forth the
terms and conditions of the Tripoint offer and provide instructions as to how to
tender your shares. The attached Schedule 14D-9 sets forth additional
information regarding the offer and the merger relevant to making an informed
decision. The Company's Information Statement pursuant to Section 14(f) of the
Securities Exchange Act of 1934 is also attached. We urge you to read these
materials carefully and in their entirety.

Vertex Communications Corporation
2600 N. Longview Street
Kilgore, Texas 75662

Attention: Board of Directors

Gentlemen:

    You have advised Frost Securities, Inc. ("FSI") that TriPoint Global
Communications ("TriPoint") has proposed to acquire 100% of the outstanding
common stock of Vertex Communications Corporation, ("Vertex" or the "Company")
at $22.00 for each share of Vertex common stock (the "Transaction"). You have
requested that FSI issue an opinion ("Opinion") as to the fairness, from a
financial point of view, to the common stockholders of Vertex of the
consideration to be received in the Transaction.

    In arriving at our Opinion we have, among other things:

        1. Reviewed the Agreement and Plan of Merger Among TriPoint and Vertex
    dated November 11, 1999 (the "Agreement");

        2. Reviewed Vertex's Annual Reports and Form 10-K reports for the fiscal
    years ended September 30, 1997 and September 30, 1998;

        3. Reviewed Vertex's Form 10-Q reports for the quarters ended July 2,
    1999, April 2, 1999, January 1, 1999, July 3, 1998, April 3, 1998 and
    January 2, 1998;

        4. Reviewed other publicly available documents filed with the U.S.
    Securities and Exchange Commission by Vertex;

        5. Discussed with management of Vertex the outlook for future operating
    results, the assets and liabilities of Vertex, material in the foregoing
    documents, and other matters we considered relevant to our inquiry; and

        6. Considered such other information, financial studies, analyses and
    investigations as we deemed relevant under the circumstances.

    In connection with our review and in arriving at our opinion, we have, with
your permission, (i) not independently verified any of the foregoing information
and have relied on its being complete and accurate in all material respects, and
(ii) not made an independent evaluation or appraisal of the specific assets of
the Company, nor have we been furnished with any such independent evaluations or
appraisals.

    Our Opinion is necessarily based solely upon the information set forth
herein as reviewed by us and circumstances existing as of the date hereof.
Events occurring after the date hereof could materially affect the assumptions
used both in preparing this opinion and in the documents reviewed by us.

    This letter shall be for the use of the Board of Directors of the Company in
considering the Transaction. The Company may not publish or refer to this letter
(either in its entirety or through excerpt or summaries) or disclose the
existence of our engagement hereunder or describe or characterize the advice
provided by us without the prior approval of FSI, which approval shall not be
<PAGE>
unreasonably withheld. It is expressly understood that this letter may be
included in certain regulatory filings, including any proxy statement to be
mailed to the stockholders of the Company in connection with the Transaction, or
as otherwise required by law, rule or regulation of any governmental authority
or the rules of the New York Stock Exchange and that such approval hereby is
provided subject to FSI's prior review of disclosures relating to FSI's
engagement and the letter.

    As part of our investment banking business, we regularly issue fairness
opinions and are continually engaged in the valuation of companies and their
securities in connection with business reorganizations, private placements,
negotiated underwritings and mergers and acquisitions. In the ordinary course of
business, FSI and its affiliates at any time may hold long or short positions,
and may trade or otherwise effect transactions as principal or for the accounts
of customers, in debt or equity securities or options on securities of the
Company.

    Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, it is our Opinion that, on the date hereof,
the proposed consideration of $22.00 per share to be received pursuant to the
Transaction is fair to the common stockholders of Vertex from a financial point
of view.

                                          Very truly yours,

                                          [LOGO]
