To the Holders of Common Stock of
Telesciences, Inc.:

                                  INTRODUCTION

     EDB 4tel Acquisition Corp., a Delaware corporation ("Purchaser") and a
wholly-owned subsidiary of EDB Business Partner ASA, a Norwegian limited company
("Parent"), hereby offers to purchase all outstanding shares of common stock,
par value $.04 per share (the shares of common stock of the Company being
hereinafter referred to as the "Shares"), of Telesciences, Inc. (the "Company"),
at a price of $8.79 per Share (such price, or such higher price per Share as may
be paid in the Offer, being referred to herein as the "Offer Price"), net to the
seller in cash, without interest thereon, upon the terms and subject to the
conditions set forth in this Offer to Purchase and in the related Letter of
Transmittal (which, together with any amendments or supplements hereto or
thereto, collectively constitute the "Offer"). The Offer is being made pursuant
to the Agreement and Plan of Merger, dated as of October 19, 1999 (the "Merger
Agreement"), among Parent, Purchaser and the Company. Tendering stockholders
will not be obligated to pay brokerage fees or commissions or, except as set
forth in Instruction 6 of the Letter of Transmittal, stock transfer taxes on the
purchase of Shares pursuant to the Offer. Purchaser will pay all fees and
expenses of American Stock Transfer & Trust Company, which is acting as the
Depositary (the "Depositary"), and Georgeson Shareholder Communications, Inc.,
which is acting as Information Agent (the "Information Agent"), incurred in
connection with the Offer and in accordance with the terms of the agreements
entered into between Purchaser and each such person. See Section 16.

     The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the Expiration Date (as defined in Section
1) that number of Shares which when added to the Shares then beneficially owned
by Parent represent at least a majority of the total number of then outstanding
Shares on the date Shares are accepted for payment (the "Minimum Condition").
Purchaser reserves the right, subject to the applicable rules and regulations of
the Securities and Exchange Commission (the "Commission"), which it presently
has no intention of exercising (and which it may not exercise without the
Company's written consent), to increase the Minimum Condition or to elect to
purchase, pursuant to the Offer, less than the minimum number of Shares which
would otherwise be required to satisfy the Minimum Condition. The Offer is not
conditioned on obtaining financing. See Section 14, which sets forth in full the
conditions to the Offer.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, (EACH
AS DEFINED BELOW) AND DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE
ADVISABLE, FAIR TO AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE
COMPANY, AND RECOMMENDS THAT THE STOCKHOLDERS OF THE COMPANY ACCEPT THE OFFER
AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

     BROOKS, HOUGHTON SECURITIES, INC., FINANCIAL ADVISOR TO THE COMPANY, HAS
DELIVERED TO THE BOARD ITS WRITTEN OPINION TO THE EFFECT THAT, AS OF OCTOBER 19,
1999, AND BASED UPON AND SUBJECT TO THE MATTERS SET FORTH THEREIN, THE $8.79 PER
SHARE CASH CONSIDERATION TO BE PAID IN THE OFFER AND THE MERGER IS FAIR FROM A
FINANCIAL POINT OF VIEW TO THE HOLDERS OF SHARES. THE FULL TEXT OF THE WRITTEN
OPINION OF BROOKS, HOUGHTON SECURITIES, INC. CONTAINING THE ASSUMPTIONS MADE,
THE MATTERS CONSIDERED AND THE SCOPE OF THE REVIEW UNDERTAKEN IN RENDERING SUCH
OPINION AS WELL AS THE LIMITATIONS OF SUCH OPINION WILL BE ATTACHED AS AN ANNEX
TO THE COMPANY'S SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9, WHICH
WILL BE MAILED TO STOCKHOLDERS WITHIN FIVE BUSINESS DAYS AFTER THE DATE OF THIS
OFFER TO PURCHASE. STOCKHOLDERS ARE URGED TO READ THE FULL TEXT OF SUCH OPINION
IN CONJUNCTION WITH THIS OFFER TO PURCHASE.

                                        1
<PAGE>   4

     The Company has represented and warranted to Purchaser that, as of October
15, 1999, after giving effect to the four-for-one stock split effective October
15, 1999, there were 1,044,631 Shares issued and outstanding and there were
outstanding options to purchase an aggregate of 309,267 Shares, 84,675 of which
were then exercisable. The Merger Agreement provides, among other things, that
the Company will not, without the prior consent of Parent, issue (i) additional
shares of capital stock of any class of the Company, or securities convertible
into any such shares, or any rights, warrants or options to acquire any such
shares or other convertible securities, other than such issuance of Shares
pursuant to the exercise of options outstanding on the date hereof, and other
than the issuance of Shares in connection with the Company's employee stock
purchase plan, or (ii) any other securities in respect of, in lieu of or in
substitution for, Shares outstanding on the date of the Merger Agreement.
Accordingly, assuming that no outstanding options are exercised or Shares are
issued pursuant to the Company employee stock purchase plan, the Minimum
Condition will be satisfied if at least 522,316 Shares, or approximately 50.1%
of the outstanding Shares as of October 15, 1999, are validly tendered and not
withdrawn prior to the Expiration Date. Assuming that no outstanding options are
exercised after the Expiration Date, if the Minimum Condition is satisfied and
Purchaser accepts for payment Shares tendered pursuant to the Offer, Purchaser
will be able to elect a majority of the members of the Company's Board of
Directors and to effect the Merger (as hereinafter defined) without the
affirmative vote of any other stockholder of the Company.

THE MERGER

     Pursuant to the Merger Agreement, following the consummation of the Offer
and the satisfaction or waiver of certain conditions, Purchaser will be merged
with and into the Company (the "Merger"), with the Company surviving the Merger
(as such, the "Surviving Corporation") as a wholly-owned subsidiary of Parent.
In the Merger, each outstanding Share (other than Shares owned by Parent,
Purchaser or any other subsidiary of Parent or held in the treasury of the
Company or by stockholders, if any, who are entitled to and who properly
exercise appraisal rights under Delaware law) will be converted into the right
to receive from the Surviving Corporation the Offer Price in cash, without
interest. The Merger is subject to a number of conditions, including approval by
stockholders of the Company, if such approval is required by applicable law. See
Section 12.

     Under the Delaware General Corporate Law ("DGCL"), if a Delaware
corporation owns 90% or more of each outstanding class of capital stock of
another corporation, it can effect a "short-form" merger with such other
corporation without prior notice to, or any other action by, any other
stockholder of such corporation. As a result, assuming no outstanding stock
options are exercised or Shares issued by the Company in connection with the
Company's employee stock purchase plan, following October 15, 1999, if Purchaser
were to acquire ownership of 940,168 Shares pursuant to the Offer, Purchaser
would own more than 90% of the Shares, the only class of capital stock of the
Company then outstanding and would be able to effect the Merger pursuant to the
"short form" merger provisions of the DGCL. See Section 15.

     Certain U.S. federal income tax consequences of the sale of Shares pursuant
to the Offer and the conversion of Shares pursuant to the Merger are described
in Section 5.

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

OFFER TO PURCHASE

1. TERMS OF THE OFFER

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of such extension or
amendment), Purchaser will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not withdrawn in accordance with
Section 3. The term "Expiration Date" means 12:00 midnight, New York City time,
on Monday, November 22, 1999, unless and until Purchaser in accordance with the
terms of the Merger Agreement has extended the period of time during which the
Offer is open, in which event the term "Expiration Date" shall mean the latest
time and date

                                        2
<PAGE>   5

at which the Offer, as so extended by Purchaser, shall expire. In the Merger
Agreement, Parent and Purchaser have agreed that if all conditions to
Purchaser's obligation to accept for payment and pay for Shares pursuant to the
Offer are not satisfied on the scheduled Expiration Date, Purchaser may, in its
sole discretion, extend the Offer from time to time until the earlier of the
consummation of the Offer or the date which is twenty (20) business days from
the Expiration Date of the Offer (such date, the "Final Date"). The Merger
Agreement further provides that Purchaser shall, subject to the terms and
conditions of the Offer, accept for payment Shares validly tendered and not
withdrawn prior to the Expiration Date as soon as it is legally permitted to do
so under applicable law; provided, however, that Purchaser shall be entitled to
extend the Offer one or more times beyond the Final Date for an aggregate period
of up to ten (10) business days if on the Final Date the conditions to the Offer
set forth in Annex A to the Merger Agreement have been satisfied or waived, but
there shall not have been tendered that number of Shares which would equal at
least ninety percent (90%) of the issued and then outstanding Shares. Purchaser
is obligated to consummate the Offer immediately upon reaching such ninety
percent (90%) threshold. The Company has agreed that it will not tender, and
will not permit any of its subsidiaries to tender, any Shares held by it or any
such subsidiary pursuant to the Offer.

     The Offer is conditioned upon the satisfaction of certain conditions set
forth in Section 14, including the Minimum Condition. The Merger Agreement
provides that no change or waiver may be made, without the prior written consent
of the Company, that (i) decreases the Offer Price, (ii) decreases the number of
Shares to be purchased in the Offer, (iii) changes the form of consideration
payable in the Offer, (iv) adds to or changes the conditions to the Offer set
forth in Section 14, (v) waives the Minimum Condition or (vi) changes any other
terms or conditions of the Offer.

     The Merger Agreement requires Purchaser to accept for payment and pay for
all Shares validly tendered and not withdrawn pursuant to the Offer if all
conditions to the Offer are satisfied on the Expiration Date. However, if
immediately prior to the scheduled Expiration Date, all conditions to the Offer
are not satisfied, Purchaser is generally obligated to extend the Offer from
time to time until the earlier of the consummation of the Offer or the date
which is twenty (20) business days from the originally scheduled Expiration
Date. If the conditions to the Offer are not satisfied prior to the Expiration
Date, Purchaser reserves the right (but shall not be obligated, except as set
forth above), subject to the terms of the Merger Agreement, to (i) decline to
purchase any of the Shares tendered and terminate the Offer, (ii) waive any of
the conditions to the Offer, to the extent permitted by applicable law, and,
subject to complying with applicable rules and regulations of the Commission,
purchase all Shares validly tendered, or (iii) extend the Offer and, subject to
the right of stockholders to withdraw Shares until the Expiration Date, retain
the Shares tendered during the period or periods for which the Offer is
extended.

     If Purchaser extends the Offer, or if Purchaser (whether before or after
its acceptance for payment of Shares) is delayed in its purchase of, or payment
for, Shares or is unable to pay for Shares pursuant to the Offer for any reason,
then, without prejudice to Purchaser's rights under the Offer, the Depositary
may retain tendered Shares on behalf of Purchaser, and such Shares may not be
withdrawn, except to the extent tendering stockholders are entitled to
withdrawal rights as described in Section 3. However, the ability of Purchaser
to delay the payment for Shares which Purchaser has accepted for payment is
limited by Rule 14e-1(c) under the Securities Exchange Act of 1934, as amended
("Exchange Act"), which requires that a bidder pay the consideration offered or
return the securities deposited by, or on behalf of, holders of securities
promptly after the termination or withdrawal of the Offer.

     Any extension of the period during which the Offer is open, delay in
acceptance for payment or payment, termination or amendment of the Offer will be
followed, as promptly as practicable, by a public announcement thereof, such
announcement in the case of an extension to be issued not later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date in accordance with the public announcement requirements of Rules
14d-4(c) and 14e-1(d) under the Exchange Act. Without limiting the obligation of
Purchaser under such rules or the manner in which Purchaser may choose to make
any public announcement, Purchaser currently intends to make announcements by
issuing a press release to the Dow Jones News Service and making any appropriate
filing with the Commission.

                                        3
<PAGE>   6

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

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

2. PROCEDURE FOR TENDERING SHARES

     To tender Shares pursuant to the Offer, either (a) a Letter of Transmittal
(or a facsimile thereof) properly completed and duly executed, together with any
required signature guarantees, or an Agent's Message (as defined below) in
connection with a book-entry transfer of Shares, and any other documents
required by the Letter of Transmittal, must be received by the Depositary at its
address set forth on the back cover of this Offer to Purchase and either (i)
certificates for the Shares to be tendered must be received by the Depositary at
such address or (ii) such Shares must be tendered pursuant to the procedures for
book-entry transfer described below and a confirmation of such delivery received
by the Depositary, in each case by the Expiration Date, or (b) the guaranteed
delivery procedure described below must be complied with. The term "Agent's
Message" means a message, transmitted by the Book-Entry Transfer Facility (as
hereinafter defined) to and received by the Depositary and forming a part of a
book-entry confirmation ("Book-Entry Confirmation") which states that the
Book-Entry Transfer Facility has received an express acknowledgment from the
participant in the Book-Entry Transfer Facility tendering the Shares which are
the subject of such book-entry confirmation that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that
Purchaser may enforce such agreement against such participant.

     Book-Entry Transfer.  The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer, and any financial institution that is a
participant in the system of the Book-Entry Transfer Facility may make a
book-entry transfer of Shares by causing the Book-Entry Transfer Facility to
transfer such Shares into the Depositary's account in accordance with the
procedures of the Book-Entry Transfer Facility. However, although delivery of
Shares may be effected through book-entry transfer at the Book-Entry Transfer
Facility, the Letter of Transmittal (or facsimile thereof) properly completed
and duly executed, together with any required signature guarantees, or an
Agent's Message and any other required documents must, in any case, be received
by the Depositary at its address set forth on the back cover of this Offer to
Purchase by the Expiration Date, or the guaranteed delivery procedure described
below must be complied with. Delivery of the Letter of Transmittal and any other
required documents to the Book-Entry Transfer Facility does not constitute
delivery to the Depositary.

     Signature Guarantees.  Except as otherwise provided below, all signatures
on a Letter of Transmittal must be guaranteed by a financial institution
(including most banks, savings and loan associations and brokerage houses) which
is a member in good standing of the Securities Transfer Association Medallion
Program, the New York Stock Exchange, Inc., Medallion Signature Program or the
Stock Exchange Medallion Program (an "Eligible Institution"). Signatures on a
Letter of Transmittal need not be guaranteed (a) if the Letter of Transmittal is
signed by the registered holder of the Shares tendered therewith and such
                                        4
<PAGE>   7

holder has not completed the box entitled "Special Payment Instructions" or the
box entitled "Special Delivery Instructions" on the Letter of Transmittal or (b)
if such Shares are tendered for the account of an Eligible Institution. If the
certificate for Shares is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or
certificates for Shares not tendered or accepted for payment are to be issued,
in the name of a person other than the registered holder(s), then the tendered
certificates must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name(s) of the registered holder(s) appear on
the certificates, with the signature(s) on the certificates or stock powers
guaranteed by an Eligible Institution. See Instructions 1 and 5 of the Letter of
Transmittal.

     Guaranteed Delivery.  If a stockholder desires to tender Shares pursuant to
the Offer and cannot deliver certificate(s) representing such Shares and all
other required documents to the Depositary by the Expiration Date, or such
stockholder cannot complete the procedure for delivery by book-entry transfer on
a timely basis, such Shares may nevertheless be tendered if all of the following
conditions are met:

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

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

          (iii) the certificates for such Shares (or a confirmation of a
     book-entry transfer of such Shares into the Depositary's account at the
     Book-Entry Transfer Facility), together with a properly completed and duly
     executed Letter of Transmittal (or facsimile thereof) with any required
     signature guarantee (or, in the case of a book-entry transfer, an Agent's
     Message) and any other documents required by the Letter of Transmittal, are
     received by the Depositary within three Nasdaq Stock Market trading days
     after the date of execution of the Notice of Guaranteed Delivery. A "Nasdaq
     Stock Market trading day" is any day on which the Nasdaq Stock Market,
     Inc.'s Nasdaq SmallCap Market is open for business.

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

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

     Backup Withholding.  Under United States federal income tax laws, the
Depositary will be required to withhold 31% of the amount of any payments made
to certain stockholders pursuant to the Offer. In order to avoid such backup
withholding, each tendering stockholder must provide the Depositary with such
stockholder's correct taxpayer identification number ("TIN") and certify that
such stockholder is not subject to backup withholding by completing the
Substitute Form W-9 included in the Letter of Transmittal. If a stockholder is a
non-resident alien or foreign entity not subject to back-up withholding, the
stockholder must give the Depositary a completed Form W-8 Certificate of Foreign
Status prior to receipt of any payment.

     Letter of Transmittal.  By executing a Letter of Transmittal, a tendering
stockholder irrevocably appoints designees of Purchaser as such stockholder's
proxies, each with full power of substitution, in the manner set forth in the
Letter of Transmittal, to the full extent of such stockholder's rights with
respect to the Shares tendered by such stockholder and accepted for payment by
Purchaser. All such proxies shall be irrevocable and coupled with an interest in
the tendered Shares. Such appointment is effective only upon the acceptance for
payment of such Shares by Purchaser. Upon such acceptance for payment, all prior
proxies and consents granted by such stockholder with respect to such Shares and
other securities will, without further action, be revoked, and no subsequent
proxies may be given nor subsequent written consents executed by such
stockholder (and, if given or executed, will not be deemed to be effective) with
respect thereto. Such designees of Purchaser will be empowered to exercise all
voting and other rights of such stockholder as they, in

                                        5
<PAGE>   8

their sole discretion, may deem proper at any annual, special or adjourned
meeting of the Company's stockholders, by written consent or otherwise.
Purchaser reserves the right to require that, in order for Shares to be validly
tendered, immediately upon Purchaser's acceptance for payment of such Shares,
Purchaser is able to exercise full voting, consent and all other rights with
respect to such Shares (including voting at any meeting of stockholders then
scheduled or acting by written consent without a meeting to the extent permitted
under Delaware law).

     The tender of Shares pursuant to any one of the procedures described above
will constitute the tendering stockholder's acceptance of the Offer, as well as
the tendering stockholder's representation and warranty that (a) such
stockholder owns the Shares being tendered within the meaning of Rule 14e-4
promulgated under the Exchange Act, (b) the tender of such Shares complies with
Rule 14e-4 and (c) such stockholder has the full power and authority to tender
and assign the Shares tendered, as specified in the Letter of Transmittal.
Purchaser's acceptance for payment of Shares tendered pursuant to the Offer will
constitute a binding agreement between the tendering stockholder and Purchaser
upon the terms and subject to the conditions of the Offer.

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

3. WITHDRAWAL RIGHTS

     Tenders of Shares made pursuant to the Offer may be withdrawn at any time
prior to the Expiration Date. Thereafter, such tenders are irrevocable, except
that they may be withdrawn after December 23, 1999 unless theretofore accepted
for payment as provided in this Offer to Purchase. If Purchaser extends the
period of time during which the Offer is open, is delayed in accepting for
payment or paying for Shares or is unable to accept for payment or pay for
Shares pursuant to the Offer for any reason, then, without prejudice to
Purchaser's rights under the Offer, the Depositary may, on behalf of Purchaser,
retain all Shares tendered, and such Shares may not be withdrawn except as
otherwise provided in this Section 3.

     To be effective, a written, telegraphic, telex or facsimile transmission
notice of withdrawal must be timely received by the Depositary at its address
set forth on the back cover of this Offer to Purchase and must specify the name
of the person who tendered the Shares to be withdrawn, the number of Shares to
be withdrawn and the name of the registered holder of Shares, if different from
that of the person who tendered such Shares. If the Shares to be withdrawn have
been delivered to the Depositary, a signed notice of withdrawal with (except in
the case of Shares tendered by an Eligible Institution) signatures guaranteed by
an Eligible Institution must be submitted prior to the release of such Shares.
In addition, such notice must specify, in the case of Shares tendered by
delivery of certificates, the name of the registered holder (if different from
that of the tendering stockholder) and the serial numbers shown on the
particular certificates evidencing the Shares to be withdrawn or, in the case of
Shares tendered by book-entry transfer, the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawn Shares.
Withdrawals of Shares may not be rescinded, and Shares properly withdrawn will
thereafter be deemed not validly tendered for purposes of the Offer. However,
withdrawn Shares may be retendered at any time prior to the Expiration Date by
following one of the procedures described in Section 2.

                                        6
<PAGE>   9

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

4. ACCEPTANCE FOR PAYMENT AND PAYMENT

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment, and will pay for, as soon as
practicable after the Expiration Date, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 3.
Purchaser expressly reserves the right to delay acceptance for payment of, or
payment for, Shares in order to comply in whole or in part with any applicable
law.

     For purposes of the Offer, Purchaser shall be deemed to have accepted for
payment tendered Shares when, as and if Purchaser gives oral or written notice
to the Depositary of its acceptance of the tenders of such Shares. Upon the
terms and subject to the conditions of the Offer, payment for Shares accepted
for payment pursuant to the Offer will be made by deposit of the purchase price
with the Depositary, which will act as agent for the tendering stockholders for
the purpose of receiving payments from Purchaser and transmitting such payments
to tendering stockholders. In all cases, payment for Shares accepted for payment
pursuant to the Offer will be made only after timely receipt by the Depositary
of (i) certificates for such Shares (or of a confirmation of a book-entry
transfer of such Shares into the Depositary's account at the Book-Entry Transfer
Facility (as defined in Section 2)), (ii) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees, or an Agent's Message in connection with a book-entry transfer, and
(iii) any other required documents. For a description of the procedure for
tendering Shares pursuant to the Offer, see Section 2. Accordingly, payment may
be made to tendering stockholders at different times if delivery of the Shares
and other required documents occur at different times. Under no circumstances
will interest be paid by Purchaser on the consideration paid for Shares pursuant
to the Offer, regardless of any delay in making such payment.

     If Purchaser increases the consideration to be paid for Shares pursuant to
the Offer, Purchaser will pay such increased consideration for all Shares
purchased pursuant to the Offer.

     UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE TO BE
PAID BY PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR
ANY DELAY IN MAKING SUCH PAYMENT.

     Subject to applicable rules and regulations of the Commission and to the
terms and conditions of the Merger Agreement, Purchaser expressly reserves the
right, in its sole discretion, to delay acceptance for payment of, or payment
for, Shares in order to comply in whole or in part with any applicable law. If
Purchaser is delayed in its acceptance for payment of, or payment for, Shares or
is unable to accept for payment or pay for Shares pursuant to the Offer for any
reason, then, without prejudice to Purchaser's rights under the Offer (but
subject to compliance with Rule 14e-1(c) under the Exchange Act), the Depositary
may, nevertheless, on behalf of Purchaser, retain tendered Shares, and such
Shares may not be withdrawn, except to the extent tendering stockholders are
entitled to exercise, and duly exercise, withdrawal rights as described in
Section 3.

     If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if certificates are submitted for more Shares than are tendered,
certificates for such unpurchased or untendered Shares will be returned (or, in
the case of Shares tendered by book-entry transfer, such Shares will be credited
to an account maintained at the Book-Entry Transfer Facility), without expense
to the tendering stockholder, as promptly as practicable following the
expiration or termination of the Offer.

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The receipt of cash in exchange for Shares pursuant to the Offer or the
Merger (and the receipt of cash by a stockholder that exercises appraisal rights
in connection with the Merger under Delaware law) will be a taxable transaction
for federal income tax purposes under the Internal Revenue Code of 1986, as
amended (the "Code"), and may also be a taxable transaction under applicable
state, local or foreign income or other tax laws. Generally, for federal income
tax purposes, a tendering stockholder will recognize gain or loss equal to the
difference between the amount of cash received by the stockholder pursuant to
the Offer or the Merger (other than amounts received pursuant to a stockholder's
exercise of appraisal rights that are denominated as interest, which amounts
would be taxable as ordinary income) and the aggregate tax basis in the Shares
tendered by the stockholder and purchased pursuant to the Offer or converted in
the Merger, as the case may be. Gain or loss will be calculated separately for
each block of Shares tendered and purchased pursuant to the Offer or converted
in the Merger, as the case may be. If Shares are held by a stockholder as
capital assets, gain or loss recognized by the stockholder will be capital gain
or loss. Such capital gain or loss will be long-term if such stockholder's
holding period for the Shares exceeds twelve months and short-term in all other
cases.

     A stockholder that tenders Shares may be subject to 31% backup withholding
unless the stockholder provides its TIN and certifies that such number is
correct or properly certifies that it is awaiting a TIN, or unless an exemption
applies. Exemptions are available for stockholders that are corporations and for
certain foreign individuals and entities. A stockholder that does not furnish a
required TIN may be subject to a penalty imposed by the Internal Revenue Service
("IRS"). See "Backup Withholding" under Section 2.

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

     The foregoing discussion is a general summary of certain material U.S.
federal income tax consequences of the Offer and the Merger relevant to a
beneficial holder of Shares whose Shares are tendered and accepted for payment
pursuant to the Offer. The discussion is based on the Code, regulations issued
thereunder, judicial decisions and administrative rulings, all of which are
subject to change with possible retroactive effect. The foregoing discussion
does not address U.S. federal income tax consequences to all categories of
holders of Shares that may be subject to special rules (e.g., holders that
acquired Shares pursuant to the exercise of employee stock options or other
compensation arrangements, holders of Shares who are subject to special tax
treatment under the Code, such as non-U.S. persons, life insurance companies,
tax-exempt organizations and financial institutions) and may not apply to other
holders of Shares in light of their individual circumstances. STOCKHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE OFFER AND THE MERGER.

announcement of the execution of the Merger Agreement, the closing bid price of
the Shares on the Nasdaq SmallCap Market was $3.125 per Share. On October 22,
1999, the last full trading day before commencement of the Offer, the closing
bid price of the Shares on the Nasdaq SmallCap Market was $8.4375 per Share.
Stockholders are urged to obtain current market quotations for the Shares.

7. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY; EFFECT OF THE OFFER ON THE
   MARKET FOR THE SHARES; STOCK QUOTATION; EXCHANGE ACT REGISTRATION; MARGIN
   REGULATIONS

     Purpose of the Offer.  The purpose of the Offer and the Merger is to enable
Parent to acquire control of, and the entire equity interest in, the Company.
Upon consummation of the Merger, the Company will become a wholly-owned
subsidiary of Parent. The Offer is being made pursuant to the Merger Agreement
and is intended to increase the likelihood that the Merger will be effected. The
purpose of the Merger is to acquire all of the outstanding Shares not purchased
pursuant to the Offer.

     Plans for the Company.  If, as and to the extent that Purchaser acquires
control of the Company, Parent and Purchaser intend to conduct a detailed review
of the Company and its assets, corporate structure, capitalization, operations,
properties, policies, management and personnel and to consider and determine
what, if any, changes would be desirable in light of the circumstances which
then exist. Such changes could include, among other things, changes in the
Company's business, corporate structure, capitalization, management or dividend
policy.

     Except as described above or elsewhere in this Offer to Purchase, Parent
has no present plans or proposals that would relate to or result in an
extraordinary corporate transaction involving the Company (such as a merger,
reorganization, liquidation, relocation of any operations or sale or other
transfer of a material amount of assets), or any material change in the
Company's corporate structure or business.

     Market for the Shares.  The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
will reduce the number of holders of Shares, which, depending upon the number of
Shares so purchased, could adversely affect the liquidity and market value of
the remaining Shares held by stockholders. Purchaser cannot predict whether the
reduction in the number of Shares that might otherwise trade publicly would have
an adverse or beneficial effect on the market price for, or marketability of,
the Shares or whether it would cause future market prices to be greater or less
than the Offer Price. If the Merger is consummated, the Company would become a
wholly-owned subsidiary of Parent and, accordingly, there would be no further
trading in the Shares.

                                        9
<PAGE>   12

     Nasdaq Quotation.  Depending upon the number of Shares purchased pursuant
to the Offer, the Shares may no longer meet the requirements for continued
inclusion on the Nasdaq SmallCap Market, which requires that an issuer have at
least 500,000 publicly held shares, held by at least 300 round lot stockholders,
with a market value of at least $1,000,000, have at least two market makers,
have a minimum bid price of $1 and have either (A) net tangible assets of at
least $2,000,000; (B) a market capitalization of at least $35,000,000; or (C)
net income of $500,000 in the most recently completed fiscal year or in two of
the last three most recently completed fiscal years. If the Nasdaq SmallCap
Market were to cease to publish quotations for the Shares, it is possible that
the Shares would continue to trade in the over-the-counter market and that price
or other quotations would be reported by other sources. The extent of the public
market for such Shares and the availability of such quotations would depend,
however, upon such factors as the number of stockholders and/or the aggregate
market value of such securities remaining at such time, the interest in
maintaining a market in the Shares on the part of securities firms, the possible
termination of registration under the Exchange Act as described below, and other
factors. Purchaser cannot determine whether the reduction in the number of
Shares that might otherwise trade publicly would have an adverse or beneficial
effect on the market price for, or marketability of, the Shares or whether it
would cause future market prices to be greater or lesser than the Offer Price.
If the Merger is consummated, the Company would become a wholly-owned subsidiary
of Parent and, accordingly, there would be no further trading in the Shares.

     Exchange Act Registration.  The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
neither listed on a national securities exchange nor held by 300 or more holders
of record. Termination of registration of the Shares under the Exchange Act
would substantially reduce the information required to be furnished by the
Company to its stockholders and to the Commission and would make certain
provisions of the Exchange Act no longer applicable to the Company, such as the
short-swing profit recovery provisions of Section 16(b), the requirement of
furnishing a proxy statement pursuant to Section 14(a) in connection with
stockholders' meetings and the related requirement of furnishing an annual
report to stockholders and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 or Rule 144A
promulgated under the Securities Act of 1933, as amended (the "Securities Act"),
may be impaired or eliminated.

     Parent currently intends to seek delisting of the Shares from the Nasdaq
SmallCap Market and the termination of the registration of the Shares under the
Exchange Act as soon after the completion of the Offer as the requirements for
such delisting and termination are met. If the Nasdaq SmallCap Market listing
and the Exchange Act registration of the Shares are not terminated prior to the
Merger, then the Shares will be delisted from the Nasdaq SmallCap Market and the
registration of the Shares under the Exchange Act will be terminated following
the consummation of the Merger.

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

(1) Purchased research and development of $2,387 in fiscal 1998 represents a
    one-time charge for in-process research and development which was purchased
    in the acquisition of IDT by the Company on May 15, 1998. The acquisition
    was accounted for under the purchase method of accounting. Purchased
    research and development of $6,700 in fiscal 1994 represents a one-time
    charge for in-process research and development which was purchased in the
    acquisition of the predecessor business by the Company on July 1, 1994. The
    acquisition was accounted for under the purchase method of accounting.
(2) The Company's acquisition of the predecessor business and other financing
    requirements have been primarily funded from borrowings from Securicor plc
    or its subsidiaries ("Securicor") rather than equity investment. These
    borrowings are classified as obligations to Securicor and affiliates.
    Additionally, these borrowings were substantially repaid with the proceeds
    from the Company's initial public offering of its Common Stock, completed in
    July 1997.

     Available Information.  The Company is subject to the informational
requirements of the Exchange Act and, in accordance therewith, is required to
file reports relating to its business, financial condition and other matters.
Information as of particular dates concerning the Company's directors and
officers, their remuneration, stock options and other matters, the principal
holders of the Company's securities and any material interest of such persons in
transactions with the Company is disclosed in the Company's proxy statement
dated February 16, 1999, and filed with the Commission. Such information should
be available for inspection at the public reference facilities of the Commission
at Room 1024, Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549,
and at the regional offices of the Commission located at Seven World Trade
Center, Suite 1300, New York, NY 10048 and Citicorp Center, 500 West Madison
Street, Suite 1400, Chicago, IL 60661. Copies of such information should be
obtainable from the Public Reference Section of the Commission upon payment of
prescribed fees. Such material should also be available for inspection at the
offices of Nasdaq Operations, 9801 Washington Blvd., Gaithersburg, Maryland
20878. The Commission also maintains a worldwide web site at http://www.sec.gov
which contains reports, proxy and information statements and other information
about companies, including the Company, that file electronically.

     Except as otherwise stated in this Offer to Purchase, the information
concerning the Company contained herein has been taken from or based upon
publicly available documents on file with the Commission and other publicly
available information. Although Purchaser and Parent do not have any knowledge
that any such information is untrue, none of Purchaser or Parent takes any
responsibility for the accuracy or completeness of such information or for any
failure by the Company to disclose events that may have occurred and may affect
the significance or accuracy of any such information.

     In the course of discussions between representatives of Parent and the
Company (see Section 11), the Company provided Purchaser with an unaudited
estimated balance sheet as of September 30, 1999 (the "Estimated September 30,
1999 Balance Sheet") and an unaudited estimated statement of operations for its
fiscal year ended September 30, 1999 (the "Estimated Fiscal 1999 Statement of
Operations") that did not reflect the Company's Series A Preferred Stock or any
adjustments based on a possible restructuring of the lease for the Company's
executive offices or on a dispute with a customer. The Estimated September 30,
1999 Balance Sheet reflects an estimated stockholders' equity of approximately
$5.4 million. The Estimated Fiscal 1999 Statement of Operations reflects the
following estimated amounts for the Company's fiscal year ended

                                       13
<PAGE>   16

September 30, 1999: Total revenues - approximately $21.1 million; gross
profit - approximately $5.3 million; operating loss - approximately $10.1
million; and net loss - approximately $12.8 million.

     The Company also provided a projected statement of operations for the
Company's fiscal year ending September 30, 2000, and projections of sales for
its fiscal years ending September 30, 2000, 2001 and 2002 (the "Projections"
and, together with the Estimated September 30, 1999 Balance Sheet and the
Estimated Fiscal 1999 Statement of Operations, the "Estimated and Projected
Financial Information"). For the fiscal year ending September 30, 2000, the
Company estimated total revenues of approximately $31.3 million, gross profit of
approximately $13.7 million, operating income of approximately $5.0 million and
net income of approximately $5.0 million. Projected sales for the fiscal year
ending September 30, 2000 were $31.3 million on a "baseline" basis and $50.3
million on a "best case" basis. Projected sales for the fiscal years ending
September 30, 2001 and 2002 were $37.0 million and $45.5 million, respectively.

     The Estimated and Projected Financial Information was provided without
detailed written assumptions. The Estimated and Projected Financial Information
was not prepared with a view to public disclosure or compliance with published
guidelines of the Commission or the guidelines established by the American
Institute of Certified Public Accountants regarding projections, and it is
summarized in this Offer to Purchase only because it was provided to Parent.
None of Parent, Purchaser, the Company, or any of their financial advisors or
other representatives assumes any responsibility for the accuracy or validity of
the Estimated and Projected Financial Information. While presented with
numerical specificity, the Projections were based upon a variety of assumptions
relating to the business of the Company which may not be realized and are
subject to significant risks, uncertainties and contingencies, many of which are
beyond the control of the Company. Actual results will vary from those shown in
the Estimated and Projected Financial Information and the positive or negative
variances may be material. Except as required by law, none of the Company,
Parent or Purchaser intends to update, revise or correct the Estimated and
Projected Financial Information if it becomes inaccurate.

9. CERTAIN INFORMATION CONCERNING PURCHASER AND PARENT

     Purchaser is a newly incorporated Delaware corporation and a wholly-owned
subsidiary of Parent organized to acquire the Company. The principal executive
offices of Purchaser are located at Ruselokkveien 6, N-0251 Oslo (Postal
Address: Postboks 6798, St. Olavs Plass, N-0130 Oslo, Norway). Purchaser has not
conducted any business, other than in connection with the Offer and the Merger
since its incorporation on October 18, 1999. Until immediately prior to the time
Purchaser purchases Shares pursuant to the Offer, it is not anticipated that
Purchaser will have any significant assets or liabilities or engage in
activities other than those incident to its formation and capitalization and the
transactions contemplated by the Offer and the Merger. Because Purchaser is a
newly formed corporation and has minimal assets and capitalization, no
meaningful financial information regarding Purchaser is available.

     Parent, a Norwegian limited company, is a publicly owned company whose
shares are listed on the Oslo Stock Exchange. Its principal executive office is
located at Ruselokkveien 6, N-0251 Oslo (Postal Address: Postboks 6798, St.
Olavs Plass, N-0130 Oslo, Norway). The principal business of Parent is supplying
both large and medium sized companies with cost-efficient and up-to-date IT
Solutions by providing consulting services and computer operating services as
well as the supply of hardware and software.

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

     Neither Parent nor Purchaser is subject to the informational requirements
of the Exchange Act and in accordance therewith does not file periodic reports,
proxy statements or other information with the Commission relating to its
business, financial condition or other matters.

     Because the only consideration in the Offer and Merger is cash, and in view
of the fact that Purchaser has deposited into escrow with First Union National
Bank a sufficient amount of funds necessary to make a cash payment to purchase
all of the Shares tendered in the Offer, Purchaser believes that the financial
condition of

                                       14
<PAGE>   17

Parent, Purchaser and their affiliates is not material to a decision by a holder
of Shares whether to tender and sell or Shares pursuant to the Offer or to
continue to hold such Shares.

     Except as described in this Offer to Purchase, (i) none of Parent,
Purchaser or, to the best knowledge of Parent and Purchaser, any of the persons
listed in Schedule I to this Offer to Purchase or any associate or
majority-owned subsidiary of Parent, Purchaser or any of the persons so listed
beneficially owns or has any right to acquire, directly or indirectly, any
Shares and (ii) none of Parent, Purchaser or, to the best knowledge of Parent
and Purchaser, any of the persons or entities referred to above or any director,
executive officer or subsidiary of any of the foregoing has effected any
transaction in the Shares during the past 60 days.

     Except as described in this Offer to Purchase, none of Parent, Purchaser
or, to the best knowledge of Parent and Purchaser any of the persons listed in
Schedule I hereto, has any contract, arrangement, understanding or relationship
with any other person with respect to any securities of the Company, including,
but not limited to, any contract, arrangement, understanding or relationship
concerning the transfer or voting of such securities, finder's fees, joint
ventures, loan or option arrangements, puts or calls, guarantees of loans,
guarantees of profits, guarantees against loss, division of profits or loss or
the giving or withholding of proxies. Except as set forth in this Offer to
Purchase, since October 1, 1996, none of Parent, Purchaser or, to the best
knowledge of Parent and Purchaser, any of the persons listed in Schedule I
hereto, has had any business relationship or transaction with the Company or any
of its executive officers, directors, or affiliates that is required to be
reported under the rules and regulations of the Commission applicable to the
Offer. Except as set forth in this Offer to Purchase, since October 1, 1996,
there have been no contracts, negotiations or transactions between Parent,
Purchaser or any of their subsidiaries or, to the best knowledge of Parent and
Purchaser any of the persons listed in Schedule I hereto, on the one hand, and
the Company or its affiliates, on the other hand, concerning a merger,
consolidation or acquisition, tender offer or other acquisition of securities,
an election of directors or a sale or other transfer of a material amount of
assets.

10. SOURCE AND AMOUNT OF FUNDS

     The Offer is not conditioned upon any financing arrangements. The total
amount of funds required by Purchaser to consummate the Offer and the Merger,
the redemption of the Company's Series A Preferred Stock and the settlement of
the Company's outstanding in-the-money stock options based on the difference
between the Offer Price and the applicable exercise price, is estimated to be
$13.65 million, exclusive of fees and expenses estimated to be $0.35 million.
Pursuant to the terms of an Escrow Agreement among Parent, Purchaser, the
Company and First Union National Bank, Purchaser has deposited into escrow with
First Union National Bank $13.65 million. Purchaser has obtained all such funds
and expects to obtain the funds necessary to pay fees and expenses from Parent
in the form of capital contributions and/or loans. Parent has provided such
funds from available cash on hand.

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

     One of Parent's strategic objectives is to grow at a faster rate than the
rate of growth of its industry. An important part of this strategy involves the
acquisition of companies within its industry. In order to implement this
strategy, Parent began seeking potential acquisition candidates primarily in the
areas of network management and customer relationship management. On June 30,
1999, the Company publicly announced its interest in investigating strategic
alternatives, including possibly a business combination. In August 1999, Parent
became aware the Company was pursuing strategic alternatives and arranged to
have a meeting with Michael Moore, Executive Vice President of the Company
during an upcoming trip of Mr. Moore's in Romania. In preparation for that
meeting, on August 26, 1999, John Freeman, Executive Director of Brooks,
Houghton Securities, Inc., the Company's financal advisor, sent Mr. Asbjorn
Eide, Chief Executive Officer of EDB 4tel, a division of Parent ("EDB 4tel"), a
confidentiality letter agreement which was signed and returned. Mr. Freeman then
provided Mr. Eide with certain non-public information about the Company.

     On August 31, 1999, Mr. Eide met with Michael Moore in Bucharest, Romania.
At the meeting, the parties exchanged general industry and company information,
including an introduction of their businesses and

                                       15
<PAGE>   18

an explanation of their current and future growth strategies. At the conclusion
of the meeting, Mr. Eide expressed to Mr. Moore Parent's possible interest in
acquiring the Company.

     On September 14 and 15, 1999, at the Company's executive offices in Mt.
Laurel, New Jersey, and on September 16, 1999, in San Diego, California, Mr.
Eide and a team of EDB 4tel employees met with the Company's executive
management to discuss the opportunities available to their respective companies
which could result from a business combination.

     During the week of September 27, 1999, EDB 4tel executives conducted
interviews with certain customers of Parent.

     On September 29, 1999, the Board of Directors of Parent met to consider the
proposed acquisition by Parent of the Company, and approved such acquisition at
a price of not more than an aggregate of $8.5 million for all of the outstanding
shares of the Company. Subsequently, Mr. Eide contacted executives of Securicor
Communications Limited ("Securicor"), the Company's largest stockholder, and
made an offer to buy Shares owned by Securicor for a purchase price of $2.40 per
Share. No response was provided by Securicor to Parent's offer.

     On October 1, 1999, Parent provided a preliminary expression of interest in
acquiring the Company at an approximate valuation of $8.5 million. The Company
and its financial advisor advised Parent that interest had been expressed by
other third parties in acquiring the Company based on a substantially higher
valuation.

     Between October 6, 1999 and October 13, 1999, there were occasional
informal communications between representatives of Parent and the Company in
which the possibility of an offer by Parent based on a higher valuation, as well
as the structure and timing of such an offer, were discussed.

     On October 12, 1999, Mr. Moore met with Mr. Eide in Oslo, Norway and
continued discussions regarding Parent's interest in acquiring the Company based
on a higher valuation.

     On October 14, 1999, the Board of Directors of Parent met to consider
increasing the purchase price of the proposed acquisition by Parent of the
Company, and approved such increase to a price of not more than an aggregate of
$13.65 million for all of the outstanding shares of capital stock of the
Company. Subsequently, Parent sent a letter to Andrew P. Maunder, President and
Chief Executive Officer of the Company, indicating that Parent was prepared to
make an offer of $13.65 million for all of the shares of the Company if the
Company would negotiate exclusively with Parent through October 17, 1999.

     On October 14, 1999, the Board of Directors of the Company met to consider
the letter from Parent and authorized the Company's management to enter into
negotiations with Parent. The preceding sentence and other descriptions
contained in this Section 11 relating to the meetings of the Company's Board of
Directors are based on information provided by the Company.

     On October 14, 1999, the Company's legal counsel sent a draft of a proposed
Merger Agreement to legal counsel for Parent. On October 15, 1999,
representatives of Parent flew to Philadelphia in preparation for negotiations
to commence on October 16, 1999.

     On October 16, 1999, executives of Parent met with executives of the
Company and the Company's financial advisor to discuss the terms of a proposed
transaction. That same day, Parent's legal counsel provided comments on the
Merger Agreement to the Company's legal counsel. Those comments were discussed
pursuant to a telephonic conference call that included executives and legal
counsel of Parent and the Company, and representatives of the Company's
financial advisor.

     Negotiation of the Merger Agreement was ongoing from October 16, 1999
through October 18, 1999. On October 17, 1999, the Board of Directors of the
Company held a special meeting at which the Board was informed as to the status
of negotiations. The Board authorized the Company's representatives to continue
negotiations at a purchase price at or above $13.65 million.

     By the morning of October 18, 1999, the Company's and Parent's
representatives reached agreement on all aspects of the Merger Agreement. A
special meeting of the Company's Board of Directors was held on the afternoon of
October 18, 1999, prior to which substantially final drafts of the Merger
Agreement and the
                                       16
<PAGE>   19

fairness opinion prepared by Brooks, Houghton Securities, Inc. were distributed.
At the meeting, the Company's President reported on the status of negotiations
with Parent. The Company's legal counsel made a presentation regarding the Board
of Director's fiduciary duties when considering the sale of the Company and then
summarized the terms and conditions of the Merger Agreement. A representative of
Brooks, Houghton Securities, Inc. then rendered its oral opinion that the
consideration to be received by the Company's common stockholders in the Offer
and the Merger, at $8.79 per share, was fair, from a financial point of view, to
the Company's common stockholders and gave a presentation on the basis of that
opinion. Following discussion of the Offer and the Merger, the Board of
Directors of the Company approved the Merger Agreement and the transactions
contemplated thereby, including the Offer and the Merger, and resolved to
recommend that the stockholders of the Company accept the Offer and tender their
Shares pursuant to the Offer and that the stockholders of the Company approve
and adopt the Merger Agreement. There were no dissents or abstentions, but one
director was unable to participate because he was not in the country.

     As of Tuesday, October 19, 1999, the parties executed and delivered the
Merger Agreement. On the morning of Tuesday, October 19, 1999, Parent and the
Company publicly announced that they had entered into the Merger Agreement.

     On October 25, 1999, Parent and Purchaser commenced the Offer.

12. THE MERGER AGREEMENT AND SHAREHOLDER AGREEMENTS

INTRODUCTION

     On October 19, 1999, Parent, Purchaser and the Company entered into the
Merger Agreement, pursuant to which Purchaser has agreed to make the Offer. The
Merger Agreement provides that, at the effective time of the Merger (the
"Effective Time"), Purchaser will be merged with and into the Company, and each
then outstanding Share (other than Shares owned by the Company, any subsidiary
of the Company, Parent, Purchaser, any other subsidiary of Parent or by
stockholders, if any, who are entitled to and who properly exercise appraisal
rights under the DGCL) will be converted into the right to receive an amount in
cash equal to the Offer Price. Each share of common stock of Purchaser issued
and outstanding immediately prior to the Effective Time will be converted into
one share of common stock of the Surviving Corporation. The Certificate of
Incorporation and Bylaws of Purchaser, as in effect immediately before the
Effective Time will be the Certificate of Incorporation and Bylaws of the
Surviving Corporation.

     Vote Required to Approve Merger.  The DGCL requires, among other things,
that the adoption of any plan of merger or consolidation of the Company must be
approved by the Board and generally by the holders of the Company's outstanding
voting securities. The Board has approved the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger;
consequently, the only additional action of the Company that may be necessary to
effect the Merger is approval by the Company's stockholders if the "short-form"
merger procedure described below is not available. Under the DGCL, the
affirmative vote of holders of a majority of the voting power of the then
outstanding Shares (including any Shares owned by Purchaser) is generally
required to approve the Merger. If Purchaser acquires, through the Offer or
otherwise, a majority of the voting power of the outstanding Shares (which would
be the case if the Minimum Condition were satisfied and Purchaser were to accept
for payment Shares tendered pursuant to the Offer and no outstanding options are
exercised after the Expiration Date), it would have sufficient voting power to
effect the Merger without the vote of any other stockholder of the Company.

     Short Form Merger Procedures.  Under the DGCL, if a corporation owns 90% or
more of each outstanding class of capital stock of another corporation, it can
effect a "short-form" merger with such corporation without prior notice to, or
any other action by, any other stockholder of such corporation. As a result,
assuming no outstanding stock options are exercised, and no shares are issued by
the Company in connection with the Company's employee stock purchase plan,
following October 15, 1999, if Purchaser were to acquire ownership of 940,168
Shares pursuant to the Offer, Purchaser would own more than 90% of the only
class of capital stock of the Company then outstanding and would be able to
effect the Merger pursuant to the "short form" merger provisions of the DGCL.
See Section 15.

                                       17
<PAGE>   20

     Stockholders Meeting.  If required by applicable law, in order to
consummate the Merger, the Company, acting through its Board, shall, subject to
the Board's fiduciary duties under applicable law, take all necessary action
pursuant to its Certificate of Incorporation and Bylaws to duly call, give
notice of, convene and hold a special meeting (the "Special Meeting") of its
stockholders as soon as practicable following the completion of the Offer
(provided that, if a Form 15 is promptly filed with the Commission after such
completion, the Board shall be entitled to delay giving notice until the
registration of the Shares under the Exchange Act has been terminated, but not
more than 100 days after the completion of the Offer) for the purpose of
considering and taking action upon the Merger Agreement. The Company shall also
prepare and file with the Commission a proxy statement in accordance with all
applicable requirements of the Exchange Act, if any.

THE MERGER AGREEMENT

     The following is a summary of certain provisions of the Merger Agreement
and Shareholders Agreement, copies of which have been filed with the Commission
as exhibits to the Schedule 14D-1 relating to the Offer and are incorporated
herein by reference. Such summaries are qualified in their entirety by reference
to the text of such agreements.

     The Offer.  The Merger Agreement provides that Purchaser will commence the
Offer and that, upon the terms and subject to the prior satisfaction or waiver
of the conditions of the Offer, Purchaser will purchase all Shares validly
tendered pursuant to the Offer and not withdrawn prior to the Expiration Date.
The obligation of Purchaser to accept for payment and pay for Shares tendered is
subject to the Minimum Condition, which is the valid tender and non-withdrawn
prior to the Expiration Date of that number of Shares which when added to any
Shares then beneficially owned by Parent represent at least a majority of the
total number of the outstanding Shares, and to the satisfaction of the other
conditions described in Annex A to the Merger Agreement. The Merger Agreement
provides that Purchaser may not, without prior written consent of the Company,
(i) decrease the Offer Price with respect to any Shares, (ii) decrease the
number of Shares to be purchased in the Offer, (iii) change the form of
consideration payable in the Offer, (iv) add to or change the conditions to the
Offer set forth in Annex A to the Merger Agreement, (v) waive the Minimum
Condition or (vi) make any other change in the terms or conditions of the Offer;
provided that, if the Merger Agreement shall not have been terminated in
accordance with the terms of the Merger Agreement, if the conditions set forth
in Annex A to the Merger Agreement are not satisfied or, to the extent permitted
by the Merger Agreement, waived by Purchaser as of the date the Offer would
otherwise have expired, then, except to the extent that such conditions are
incapable of being satisfied, Purchaser will extend the Offer from time to time
until the earlier of the consummation of the Offer or the date which is twenty
(20) business days from the Expiration Date of the Offer (such date, the "Final
Date"). The Merger Agreement further provides that Purchaser shall, subject to
the terms and conditions of the Offer, accept for payment Shares validly
tendered and not withdrawn prior to the Expiration Date as soon as it is legally
permitted to do so under applicable law; provided, however, that Purchaser shall
be entitled to extend the Offer one or more times beyond the Final Date for an
aggregate period of up to ten (10) business days if on the Final Date the
conditions to the Offer set forth in Annex A to the Merger Agreement have been
satisfied or waived, but there shall not have been tendered that number of
Shares which would equal at least ninety percent (90%) of the issued and then
outstanding Shares. Purchaser is obligated to consummate the Offer immediately
upon reaching such ninety percent (90%) threshold. The Company has agreed that
it will not tender, and will not permit any of its subsidiaries to tender, any
Shares held by it or any such subsidiary pursuant to the Offer.

     Conditions to the Merger.  The Merger Agreement provides that the
obligations of Parent, Purchaser and the Company to consummate the Merger are
subject to the satisfaction of certain conditions, including the following:

     - the Merger Agreement shall have been adopted by the affirmative vote of
       the stockholders of the Company at a Special Meeting by the requisite
       vote in accordance with applicable law, if such vote is required by
       applicable law;

                                       18
<PAGE>   21

     - all regulatory approvals required to consummate the transactions
       contemplated hereby shall have been obtained and shall remain in full
       force and effect and all statutory waiting periods in respect thereof
       shall have expired;

     - no statute, rule or regulation shall have been enacted or promulgated by
       any governmental authority which prohibits the consummation of the
       Merger;

     - there shall be no order or injunction of a United States Federal or state
       court of competent jurisdiction (each party agreeing to use its
       reasonable efforts to have any such order reversed or injunction lifted)
       in effect precluding consummation of the Merger; and

     - Purchaser shall have purchased the Shares pursuant to the Offer;
       provided, however, that this condition shall be deemed satisfied with
       respect to Parent and Purchaser if Purchaser's failure to purchase Shares
       pursuant to the Offer results from a breach of the Parent's or
       Purchaser's obligations under the Merger Agreement.

     Board Recommendation.  The Company represents in the Merger Agreement that
the Board has (1) determined that the terms of the Offer and the Merger are
advisable, fair to and in the best interests of, the stockholders of the
Company, (2) approved the Merger Agreement and the transactions contemplated
thereby, including the Offer and the Merger, and (3) resolved to recommend that
stockholders of the Company accept the Offer and tender their Shares pursuant to
the Offer, the Merger Agreement and the transactions contemplated thereby,
including the Merger. The Company has agreed to file with the Commission a
Solicitation/Recommendation Statement on Schedule 14D-9 containing such
recommendations, subject to certain conditions.

     Termination of the Merger Agreement.  The Merger Agreement may be
terminated and the Merger may be abandoned at any time notwithstanding approval
thereof by the stockholders of the Company, but prior to the Effective Time:

          (a) by mutual consent of Parent and the Company;

          (b) by Parent or Purchaser, if an occurrence or circumstance (except
     where Parent's or Purchaser's failure to fulfill any of their respective
     obligations under the Merger Agreement is the cause of or resulted in such
     occurrence or circumstance or except where there has been a material breach
     of any representation or warranty on the part of Parent or Purchaser which
     has not been cured) has rendered the conditions set forth in Annex A of the
     Merger Agreement incapable of being satisfied, and (i) Purchaser shall have
     failed to commence the Offer within the time required by Regulation 14D
     under the Exchange Act, (ii) the Offer shall have been terminated or shall
     have expired without Purchaser having purchased any Shares pursuant to the
     Offer or (iii) Purchaser shall have failed to pay for Shares pursuant to
     the Offer prior to the Final Date;

          (c) by either Parent or the Company if any court of competent
     jurisdiction or other governmental body within the United States shall have
     issued an order, decree or ruling or taken any other action permanently
     restraining, enjoining or otherwise prohibiting the Merger and such order,
     decree, ruling or other action shall have become final and non-appealable;
     provided, however, that a termination of the Merger Agreement by the
     Company pursuant to this paragraph (c) after the Board Transition Date (as
     defined in the Merger Agreement) shall require the affirmative vote of a
     majority of the Board and a majority of the Independent Directors (as
     defined below);

          (d) by Parent or Purchaser prior to the purchase of Shares pursuant to
     the Offer, if:

             (i) Purchaser shall discover that any representation or warranty
        made by the Company in the Merger Agreement is untrue at the time such
        representation or warranty was made or (except for those representations
        and warranties made as of a particular date which need only be true and
        correct as of such date) shall not be true and correct as of the date of
        consummation of the Offer, except where the failure to be so true and
        correct would not have a Material Adverse Effect (as defined in the
        Merger Agreement), provided that, if any such failure to be so true and
        correct is

                                       19
<PAGE>   22

        capable of being cured prior to the Final Date, then Parent and
        Purchaser may not terminate the Merger Agreement under this paragraph
        (d) until the Final Date;

             (ii) there shall have been a breach of any covenant or agreement on
        the part of the Company under the Merger Agreement resulting in a
        Material Adverse Effect which shall not be capable of being cured prior
        to the Final Date;

             (iii) the Board (x) fails to recommend approval and adoption of the
        Merger Agreement and the Merger by the stockholders of the Company or
        withdraws or amends or modifies in a manner adverse to Parent and
        Purchaser its recommendation or approval in respect of the Merger
        Agreement, the Offer or the Merger, (y) makes any recommendation with
        respect to an Alternative Acquisition (as defined below) other than a
        recommendation to reject such Alternative Acquisition or (z) publicly
        announces its intention to enter into an Alternative Acquisition; or

             (iv) there shall not have been validly tendered and not withdrawn
        prior to the expiration of the Offer at least a majority of the then
        outstanding Shares, and on or prior to such date a person shall have
        made a written proposal to the Company and not withdrawn such proposal
        for an Alternative Acquisition;

          (e) by the Company, if:

             (i) the Company discovers that any representation or warranty made
        by Parent or Purchaser in the Merger Agreement is untrue at the time
        such representation or warranty was made or (except for those
        representations and warranties made as of a particular date which need
        only be true and correct as of such date) shall not be true and correct
        as of the date of consummation of the Offer, except where the failure to
        be so true and correct would not materially adversely affect (or
        materially delay) the consummation of the Offer or the Merger, provided
        that if any such failure to be so true and correct is capable of being
        cured prior to the Final Date, then the Company may not terminate the
        Merger Agreement under this paragraph (e) until the Final Date and
        unless at such time the matter has not been cured;

             (ii) there shall have been a material breach of any covenant or
        agreement in the Merger Agreement on the part of Parent or Purchaser
        which materially adversely affects (or materially delays) the
        consummation of the Offer or the Merger which shall not be capable of
        being cured prior to the Final Date;

             (iii) prior to the acceptance of any Shares pursuant to the Offer
        and the Company is in compliance with the non-solicitation provisions
        described below, such termination is necessary to allow the Company to
        enter into a binding written agreement with respect to a Superior
        Proposal (as defined below); provided, however, that a termination of
        the Merger Agreement by the Company pursuant to paragraphs (e)(i) or
        (ii) above after the Board Transition Date (as defined below) shall
        require the affirmative vote of a majority of the Board and a majority
        of the Independent Directors; or

          (f) by the Company, if there shall not have been a material breach of
     any representation, warranty, covenant or agreement on the part of the
     Company which has not been cured and (i) Purchaser shall have failed to
     commence the Offer within the time required by Regulation 14D under the
     Exchange Act, (ii) the Offer shall have been terminated or shall have
     expired without Purchaser having purchased any Shares pursuant to the Offer
     or (iii) Purchaser shall have failed to pay for Shares pursuant to the
     Offer prior to the Final Date.

     An "Alternative Acquisition" is the possible acquisition of the Company
(whether by way of merger, purchase of capital stock, purchase of assets or
otherwise) or any material portion of its capital stock or assets (with any such
efforts by any such person, including a firm proposal to make such an
acquisition).

     A "Superior Proposal" is an unsolicited proposal by any person, entity or
group delivered to the Company, prior to the consummation of the Offer and in
writing, for an Alternative Acquisition which is not subject to any financing
contingency, which the Board by a majority vote in its good faith judgment
(after
                                       20
<PAGE>   23

consultation with its independent financial advisor) determines is reasonably
likely to be consummated and if consummated will be more favorable, from a
financial point of view, to the holders of the Shares than the transactions
contemplated by the Merger Agreement.

     Termination Fees and Expenses.  The Merger Agreement provides that the
Company will pay, or cause to be paid, to Parent $400,000 as a termination fee
within two business days after the date of termination if (i) the Company
terminates the Merger Agreement in accordance with the provision described in
paragraph (e)(iii) under "Termination of Merger Agreement" above, or (ii)
Purchaser terminates the Merger Agreement in accordance with the provisions
described in paragraph (d)(iii) under "Termination of Merger Agreement" above,
at any time after a proposal for an Alternative Acquisition has been made. The
Company will also pay or cause to be paid, to Purchaser the Purchaser Expenses
(as defined below) upon demand if Parent or Purchaser terminates the Merger
Agreement in accordance with the provision described in paragraph (d)(i) or
(d)(ii) under "Termination of Merger Agreement" above. "Parent Expenses" mean
reasonable and reasonably documented out-of-pocket fees and expenses incurred or
paid by or on behalf of Parent and its subsidiaries in connection with the Offer
and the Merger or the consummation of any of the transactions contemplated by
the Merger Agreement; provided, that in no event shall Parent Expenses exceed
$100,000 (which $100,000 limit shall not apply in the event of a breach by the
Company of the Merger Agreement).

     The Merger Agreement also provides that Parent will pay, or cause to be
paid, to the Company the Company Expenses (as defined below) upon demand if the
Company terminates the Merger Agreement in accordance with the provision
described in paragraph (e)(i), (e)(ii) or (f)(i) under "Termination of Merger
Agreement" above. Company Expenses shall mean reasonable and reasonably
documented out-of-pocket fees and expenses incurred or paid by or on behalf of
the Company in connection with the Offer and the Merger or the consummation of
any of the transactions contemplated by the Merger Agreement; provided, that in
no event shall Company Expenses exceed $100,000. The foregoing does not,
however, limit the Company's right to pursue remedies for breach of the Merger
Agreement.

     In addition, no fee or expense reimbursement will be paid to any party who
is in material breach of its obligations under the Merger Agreement.

COVENANTS

     Conduct of Business by the Company.  The Company has agreed that, except as
contemplated by the Merger Agreement, during the period from the date of the
Merger Agreement to such time at which directors of the Company affiliated with
or designated by Parent or Purchaser shall constitute a majority of the Board
(such time, the "Board Transition Date"), the Company and its subsidiaries will
each conduct its operations according to its ordinary and usual course of
business, substantially consistent with past practice.

     Without limiting the generality of the foregoing, and except as otherwise
contemplated by the Merger Agreement, neither the Company nor any of its
subsidiaries will, prior to the Board Transition Date, without the prior written
consent of Parent:

          (i) issue, sell or pledge, or authorize or propose the issuance, sale
     or pledge of (A) additional shares of capital stock of any class of the
     Company, or securities convertible into any such shares, or any rights,
     warrants or options to acquire any such shares or other convertible
     securities, other than such issuance of Shares pursuant to the exercise of
     options outstanding on the date hereof, and other than the issuance of
     Shares in connection with the Company's employee stock purchase plan, or
     (B) any other securities in respect of, in lieu of or in substitution for,
     Shares outstanding on the date of the Merger Agreement,

          (ii) purchase or otherwise acquire, or propose to purchase or
     otherwise acquire, any outstanding Shares,

          (iii) declare or pay any dividend or distribution on any shares of its
     capital stock,

          (iv) propose or adopt any amendments to its Amended and Restated
     Certificate of Incorporation, as amended, or Amended and Restated Bylaws,
     or

                                       21
<PAGE>   24

          (v) agree in writing or otherwise to take any of the foregoing actions
     or any action which would prevent the conditions to Purchaser's obligation
     to purchase Shares under the Offer or Parent's and Purchaser's obligation
     to consummate the Merger from being satisfied; provided, however, that the
     Company shall be permitted to accelerate the vesting schedule of all
     outstanding Options. The Company shall, through its Board or any committee
     thereof, terminate the Company's Employee Stock Purchase Plan so that no
     Shares shall be issued thereunder subsequent to the date of the Merger
     Agreement.

     Indemnification and Insurance.  In the Merger Agreement, Parent and
Purchaser have agreed that all rights to indemnification existing in favor, and
all limitations on the personal liability of, each present and former director,
officer, employee or agent of the Company or any of its subsidiaries or a
director, officer, employee, agent or trustee of any employee benefit plan for
employees of the Company or any of its subsidiaries, and each person who is or
was then serving in any such capacity (or any person who is or was then serving
any other corporation or entity in any such capacity at the request of the
Company) (individually, an "Indemnified Party" and collectively, the
"Indemnified Parties") provided for in the Company's Amended and Restated
Certificate of Incorporation, as amended, or Amended and Restated Bylaws or
similar organizational documents of any Company subsidiary as in effect on the
date of the Merger Agreement with respect to matters occurring prior to the
Effective Time shall survive the Merger and shall continue in full force and
effect for a period of not less than six (6) years from the Effective Time;
provided, however, that all rights to indemnification in respect of any claim
for indemnification for losses, damages or liabilities of any kind or nature
incurred (an "Indemnifiable Claim") which is asserted or made within such period
shall continue until the final disposition of such claim. The Merger Agreement
further provides that Parent has agreed that it shall indemnify any Indemnified
Party in respect of any Indemnifiable Claim to the extent that the Company does
not promptly indemnify such party for an Indemnifiable Claim.

     The Merger Agreement provides that Parent and the Surviving Corporation
shall cause to be put into effect by the completion of the Offer, with a carrier
satisfactory to the Board on the date of the Merger Agreement, directors' and
officers' liability insurance covering each Indemnified Party who is currently
covered by the Company's directors' and officers' liability insurance with
respect to claims arising from facts or events which occurred at or prior to the
Effective Time, which insurance shall remain in effect for a period of at least
six (6) years after the Effective Time and which shall be no less favorable than
such insurance maintained in effect by the Company on the date of the Merger
Agreement in terms of coverage and amounts; provided that, in no event shall the
Surviving Corporation be required to make annual premium payments for such
insurance in excess of $150,000.

     Other Covenants.  The Merger Agreement further provides that; except as set
forth on the Disclosure Schedule or contemplated by the Merger Agreement, from
the date of the Merger Agreement to the Board Transition Date (as defined in the
Merger Agreement), (i) the Company will not, and will not permit any of its
subsidiaries to, merge or consolidate with any other person or acquire a
material amount of stock or assets of any other person; (ii) the Company will
not, and will not permit any of its subsidiaries to, sell, lease, license or
otherwise dispose of any material subsidiary or material amount of assets,
securities or property except (A) pursuant to existing contracts or commitments

the Company will (and will cause its subsidiaries to) use reasonable efforts not
to, (A) take any action that (x) would make any representation and warranty of
the Company in the Merger Agreement that is qualified by materiality or Material
Adverse Effect inaccurate in any respect at, or as of any time prior to, the
Effective Time or (y) would make any representation or warranty of the Company
in the Merger Agreement that is not so qualified to be inaccurate in any
material respect at, or as of any time prior to, the Effective Time or (B) omit
to take any action necessary to prevent any such representation or warranty from
being inaccurate in any respect or material respect, as the case may be, at any
such time; (iv) the Company will not, and will not permit any of its
subsidiaries to, sell, transfer, license, sublicense or otherwise dispose of any
material intellectual property rights (other than in the ordinary course of
business consistent with past practice) or amend or modify any existing
agreements with respect to any material intellectual property rights or third
party intellectual property rights; (v) the Company will not, and will not
permit any of its subsidiaries to, (A) incur any indebtedness for borrowed money
or issue any debt securities or assume, guarantee or endorse or otherwise as an
accommodation become responsible for, the obligations of any other person (other
than

                                       22
<PAGE>   25

(x) for an amount not exceeding $4,000,000 in the aggregate, or make any loans,
advances, or capital contributions to, or investments in, any other person, (B)
enter into or amend any contract or agreement other than in the ordinary course
of business consistent with past practice, (C) authorize or make any capital
expenditures or purchases of fixed assets that are not currently budgeted and
that in the aggregate exceeds $1,000,000, (D) terminate any material contract to
which the Company is a party or amend in any material respect any such material
contract or (E) enter into or amend any contract, agreement, commitment or

to change accounting policies or procedures or cash maintenance policies or
procedures (including, without limitation, procedures with respect to revenue
recognition, capitalization of development costs, payments of accounts payable
and collection of accounts receivable); (vii) the Company will not, and will not
permit any of its subsidiaries to, make any tax election not required by law and
inconsistent with past practice or settle or compromise any tax liability,
except to the extent the amount of any such settlement or compromise has been
reserved for on the consolidated financial statements contained in the Company's
filings with the Commission, (viii) the Company will not, and will not permit
any of its subsidiaries to, pay, discharge, settle, or satisfy any lawsuits,
claims, liabilities or obligations (absolute, accrued, asserted or unasserted,
contingent or otherwise), other than the payment, discharge or satisfaction in
the ordinary course of business consistent with past practice of liabilities
reflected or reserved against on the Estimated September 30, 1999 Balance Sheet
or incurred in the ordinary course of business consistent with past practice or
other payments, discharges or satisfactions which in the aggregate do not exceed
$1,000,000 or waive the benefits of, or agree to modify in any manner, any
confidentiality or standstill agreement.

     No Solicitation.  The Merger Agreement provides that, until the earlier of
the Board Transition Date (as defined in the Merger Agreement) or the
termination of the Merger Agreement, the Company will not directly or indirectly
(i) solicit, engage in discussions or negotiate with any person (whether such
discussions or negotiations are initiated by the Company or otherwise) or take
any other action intended or designed to facilitate the efforts of any person
(other than Parent) relating to the possible acquisition of the Company (whether
by way of merger, purchase of capital stock, purchase of assets or otherwise) or
any material portion of its capital stock or assets, (ii) provide information
with respect to the Company to any person, other than Parent, relating to a
possible Alternative Acquisition by any person, other than the Parent, (iii)
enter into an agreement with any person, other than Parent, providing for a

recommendation or solicitation in support of any possible Alternative
Acquisition by any person, other than by Parent.

     The Merger Agreement provides that the Company shall and shall cause its
representatives to, cease immediately and cause to be terminated all activities,
discussions and negotiations, if any, conducted prior to the date of the Merger
Agreement with respect to any Alternative Acquisition. Notwithstanding the
foregoing, prior to the consummation of the Offer, the Company may participate
in discussions or negotiations with, and furnish non-public information, and
afford access to the properties, books, records, officers, employees and
representatives of the Company to any person, entity or group if such person,
entity or group has delivered a Superior Proposal to the Company. In the event
the Company receives a Superior Proposal, nothing contained in the Merger
Agreement will prevent the Board from executing or entering into an agreement
relating to such Superior Proposal and recommending such Superior Proposal to
its stockholders; in such case, the Board may withdraw, modify or refrain from
making its recommendation of the Offer and the Merger; provided, however that
the Company (i) shall have promptly notified Parent, and in any event within 24
hours, of any proposal for an Alternative Acquisition received by, any such
information requested from, or any such negotiations or discussions sought to be
initiated or recommended with, the Company or any of its subsidiaries,

detailed description of the significant terms and conditions thereof).
                                       23

     Control of Board of Directors.  The Merger Agreement provides that, subject
to the requirements of applicable law, promptly upon the purchase of not less
than a majority of the outstanding Shares by Purchaser pursuant to the Offer and
from time to time thereafter, subject to Section 1.03(c) of the Merger Agreement
(relating to the appointment of Independent Directors (as defined below)),
Purchaser shall be entitled to designate up to such number of directors, rounded
up to the next whole number plus one, on the Board as will give Purchaser
representation on the Board equal to the product of the total number of
directors on the Board, after giving effect to such representation, and the
percentage that such number of Shares so purchased bears to the total number of
issued and outstanding Shares, and the Company shall use its reasonable efforts
to, upon request by Purchaser, promptly, at the Company's election, either
increase the size of the Board or secure the resignation of such number of
directors as is necessary to enable Purchaser's designees to be elected to the
Board and shall cause Purchaser's designees to be so elected, but in no event
less than a majority of directors. At such times the Company will use its
reasonable efforts to cause individuals designated by Purchaser to constitute
the same percentage as is on the Board of (i) each committee of the Board (other
than any committee of the Independent Directors), (ii) each board of directors
of each subsidiary of the Company designated by Purchaser and (iii) each
committee of each such board.

     The Merger Agreement provides that the Company's obligation to appoint
designees to the Board shall be subject to Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder. The Company agreed to promptly take all
actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill
its obligations under this provision of the Merger Agreement and to include in
the Schedule 14D-9 such information with respect to the Company and its officers
and directors as is required under Section 14(f) and Rule 14f-1. Parent or
Purchaser will supply to the Company has in writing and be solely responsible
for any information with respect to any of them and their nominees, officers,
directors and affiliates required by Section 14(f) and Rule 14f-1.

     Pursuant to the Merger Agreement, after the time that Purchaser's designees
constitute at least a majority of the Board and until the Effective Time, the
Board shall always have at least two members (the "Independent Directors") who
are neither officers of Parent nor designees, stockholders or affiliates of
Parent or Parent's affiliates. During such period, any (i) amendment or
termination of the Merger Agreement, (ii) extension of time for the performance
or waiver of the obligations or other acts of Parent or Purchaser or waiver of
the Company's rights under the Merger Agreement, or (iii) action by the Company
with respect to the Merger Agreement and the transactions contemplated thereby
which adversely affects the interests of the stockholders of the Company, shall
require the approval of a majority of the Independent Directors in addition to
any required approval thereof by the full Board.

     Stock Options.  Pursuant to the Merger Agreement, on the latest of (i) the
completion of the Offer, (ii) the first business day of January 2000 and (iii)
the earlier of (A) 30 days after termination notice is given in accordance with
the terms of the plan governing the Options (as defined below) and (B) the date
that the Option holder agrees to the treatment provided in Section 2.08 of the
Merger Agreement, each holder of then outstanding options to purchase Shares
granted by the Company (whether or not then currently exercisable) (the
"Options") will be entitled to receive, and shall receive, at the sole election
of the holder of such Option in settlement of each Option where the amount set
forth in clause (i) below is a positive amount, a cash payment from the Company
in an amount equal to the product of (i) the Offer Price minus the exercise
price per Share of the Option and (ii) the number of Shares covered by such
Option. Such payment shall be reduced by any applicable withholding taxes. The
Company, acting through its Board or any committee thereof, has the right at any
time or from time to time following the execution of the Merger Agreement to
accelerate and vest, in full or in part, any and all Options not currently
exercisable in full. Effective as of the Effective Time of the Merger, the
Company, acting through its Board or a committee thereof, shall terminate those
Options with an exercise price that is greater than the Offer Price.

     Representations and Warranties.  The Merger Agreement contains various
customary representations and warranties of the parties thereto, including
representations by the Company as to, among other things, organization,
capitalization, subsidiaries, compliance with laws and court orders, absence of
certain changes since June 30, 1999, undisclosed liabilities, public filings,
consents and approvals, litigation, title to properties, benefit plans, taxes,
and patents, trademarks and trade names. In addition, Parent and Purchaser have
                                       24

represented as to, among other things, organization and good standing, corporate
authorizations, consents and approvals and ownership of Shares.

SHAREHOLDER AGREEMENTS

     On October 19, 1999, Parent, Purchaser and each of Michael Moore ("Moore")
and Frances Penfold ("Penfold") entered into a shareholder agreement
(collectively the "Shareholder Agreements"). Pursuant to the terms of the
Shareholder Agreements, at least two (2) business days prior to the consummation
by Purchaser of the Offer, Moore and Penfold shall tender to the Depositary (i)
letters of transmittal with respect to an aggregate of 198,597 Shares (the
"Executive Shares") and any other Shares held by Moore and Penfold, (ii) the
certificates representing the Executive Shares, and (iii) all other documents or
instruments required to be delivered pursuant to the terms of the Offer to
Purchase. The Shareholder Agreements provide that Moore and Penfold may decline
to tender, or may withdraw, any and all Executive Shares or other Shares held by
them if Purchaser amends the Offer Price to less than $8.79 per Share, reduces
the number of Shares subject to the Offer, changes the form of consideration
payable in the Offer in a manner adverse to the stockholders of the Company
(other than insignificant changes or amendments or other than to waive any
conditions. Moore and Penfold are required to give Purchaser at least two (2)
business days prior notice of any withdrawal of the Executive Shares. The
Shareholder Agreements further provide that, so long as the Merger Agreement is
in effect, or Purchaser notifies Moore or Penfold of its intent to continue the
Offer or a revised offer within two (2) business days after the date of
termination of the Merger Agreement, Moore and Penfold will (i) vote all
Executive Shares now or hereafter owned by them or execute a consent or proxy,
and not revoke any proxy, vote or a consent, in favor of the Merger Agreement,
the Merger and the transactions contemplated thereby, and (ii) oppose any
Alternative Acquisition and vote all Executive Shares now or hereafter owned by
them, or execute a consent or proxy, against any Alternative Acquisition.

distributions in respect of, any of its capital stock, or (b) issue or sell any
shares of any class of its capital stock, or any securities convertible into or
exchangeable for any such shares, or issue, sell, grant or enter into any
subscriptions, options, warrants, conversion or other rights, agreements,
commitments, arrangements or understandings of any kind, contingently or
otherwise, to purchase or otherwise acquire any such shares or any securities
convertible into or exchangeable for any such shares.

not in limitation of) Purchaser's rights to extend and amend the Offer at any
time in its sole discretion (subject to the terms of the Merger Agreement),
Purchaser shall not be required to accept for payment (whether or not the Shares
have theretofore been accepted for payment), or pay for, and may delay the
acceptance for payment of, or the payment for, any tendered Shares, and may

outstanding Shares (the "Minimum Condition"), (ii) all regulatory approvals
required to consummate the Offer and the Merger shall have been obtained and

respect thereof shall have expired; or (iii) on or after date of the Merger

have occurred:

          (a) there shall be pending any action, investigation, proceeding,
     claim or counterclaim by any governmental authority or agency which seeks
     to: (i) prohibit the making or consummation of the Offer or the Merger;
     (ii) restrain or prohibit the performance of the Merger Agreement; (iii)

     ownership or operation of all or any portion of the business and assets of

     subsidiaries; or (v) to impose limitations on the ability of Parent and its
     affiliates to exercise full voting rights or ownership of the Shares; or
     that otherwise is reasonably likely to have a Material Adverse Effect (as
     defined in the Merger Agreement); or

          (b) there is in effect any order, decree or injunction (whether
     preliminary, final or appealable, other than a temporary restraining order)
     issued by a court or governmental authority of competent jurisdiction which
     prohibits consummation of the Offer or the Merger or requires Parent or
     Purchaser to hold separate any material portion of the stock or assets of
     the Company or its subsidiaries; or

          (c) there shall have been any statute, rule, regulation, injunction,
     order or decree proposed, enacted or promulgated or any similar action
     taken or deemed applicable to the Offer or the Merger which prohibits
     consummation of the Offer or the Merger; or

          (d) there shall be in effect a banking moratorium or any suspension of
     payments in respect of banks in the United States (whether or not

     the date of consummation of the Offer (except for those representations and
     warranties made as of a particular date which need only be true and correct
     as of such date), except where the failure to be so true and correct would
     not have a Material Adverse Effect; or

          (f) there shall have been a breach in any material respect by the
     Company of any of its covenants or agreements contained in the Merger
     Agreement, except for any such breaches that would not have a Material
     Adverse Effect; or

          (g) the Merger Agreement shall have been terminated in accordance with
     its terms;

          (h) any person shall have entered into a definitive agreement or an
     agreement in principle with the Company regarding an Alternative
     Acquisition; or

          (i) the Company's Board of Directors will have withdrawn or modified
     (including by amendment of the Schedule 14D-9) in a manner adverse to
     Parent or Purchaser its approval or recommendation of the Offer, the Merger
     Agreement or the Merger, will have recommended to the Company's
     stockholders another offer or will have adopted any resolution to effect
     any of the foregoing which, in the sole judgment of Purchaser in any such
     case, and regardless of the circumstances (including any action or omission
     by Purchaser) giving rise to any such condition, makes it inadvisable to
     proceed with such acceptance or payment.

     The foregoing conditions are for the sole benefit of Purchaser and may be
asserted by Purchaser regardless of the circumstances giving rise to such
condition or may be waived by Purchaser in whole or in part at any time and from
time to time in its sole discretion, subject in each case to the terms of the
Merger Agreement and applicable law. The failure by Purchaser at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right and may be asserted
at any time and from time to time.

15. CERTAIN LEGAL MATTERS

  General.

     Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning the Company and discussions of representatives
of Parent with representatives of the Company, neither Purchaser nor Parent is
aware of any license or regulatory permit that appears to be material to the
business of the Company and its subsidiaries, taken as a whole, that might be
adversely affected by Purchaser's acquisition of Shares (and the indirect
acquisition of the capital stock of the Company's subsidiaries) as contemplated
herein or of any approval or other action by any governmental entity that would
be required or desirable for the acquisition or

                                       26
<PAGE>   29

ownership of Shares by Purchaser as contemplated herein. Should any such
approval or other action be required or desirable, Purchaser and Parent
currently contemplate that such approval or other action will be sought, except
as described below under "Other State Takeover Laws". While, except as otherwise
expressly described in this Section 15, Purchaser does not presently intend to
delay the acceptance for payment of or payment for Shares tendered pursuant to
the Offer pending the outcome of any such matter, there can be no assurance that
any such approval or other action, if needed, would be obtained or would be
obtained without substantial conditions or that failure to obtain any such
approval or other action might not result in consequences adverse to the
Company's business or that certain parts of the Company's business might not
have to be disposed of if such approvals were not obtained or such other actions
were not taken or in order to obtain any such approval or other action. If
certain types of adverse action are taken with respect to the matters discussed
below, Purchaser could decline to accept for payment or pay for any Shares
tendered. See Section 14.

     Under the DGCL, the affirmative vote of holders of a majority of the voting
power of the then outstanding Shares (including any Shares owned by Purchaser)
is generally required to approve the Merger. If Purchaser acquires, through the
Offer or otherwise, a majority of the voting power of the outstanding Shares
(which would be the case if the Minimum Condition were satisfied and Purchaser
were to accept for payment Shares tendered pursuant to the Offer (and no
outstanding Options were exercised after the Expiration Date and no Shares were
issued by the Company in connection with the Company's employee stock purchase
plan), it would have sufficient voting power to effect the Merger without the
vote of any other stockholders of the Company.

     Under the DGCL, if a corporation owns 90% or more of each outstanding class
of capital stock of another corporation, it can effect a "short-form" merger
with such corporation without prior notice to, or any other action by, any other
stockholder of such corporation. As a result, assuming no Options are exercised
following October 19, 1999, if Purchaser were to acquire ownership of 940,168
Shares pursuant to the Offer, Purchaser would own more than 90% of the only
class of capital stock of the Company then outstanding and would be able to
effect the Merger pursuant to the "short form" merger provisions of the DGCL.

  Section 203 of the DGCL.

     Section 203 of the DGCL, in general, prohibits a Delaware corporation such
as the Company from engaging in a "Business Combination" (defined as a variety
of transactions, including mergers, as set forth below) with an "Interested
Stockholder" (defined generally as a person that is the beneficial owner of 15%
or more of a corporation's outstanding voting stock) for a period of three years
following the date that such person became an Interested Stockholder, unless,
among other things, prior to the date such person became an Interested
Stockholder, the board of directors of the corporation approved either the
Business Combination or the transaction that resulted in the stockholder
becoming an Interested Stockholder. The Company's Board of Directors has
approved the Merger Agreement and Purchaser's acquisition of Shares pursuant to
the Offer. Therefore, Section 203 of the DGCL is inapplicable to the Merger.

  Other State Takeover Laws.

     A number of states throughout the United States have enacted takeover
statutes that purport, in varying degrees, to be applicable to attempts to
acquire securities of corporations that are incorporated or have assets,
stockholders, executive offices or places of business in such states. In Edgar
v. MITE Corp., the Supreme Court of the United States held that the Illinois
Business Takeover Act, which involved state securities laws that made the
takeover of certain corporations more difficult, imposed a substantial burden on
interstate commerce, and, therefore, was unconstitutional. In CTS Corp. v.
Dynamics Corp. of America, however, the Supreme Court of the United States held
that a state may, as a matter of corporate law and, in particular, those laws
concerning corporate governance, constitutionally disqualify a potential
acquiror from voting on the affairs of a target corporation without prior
approval of the remaining stockholders, provided that such laws were applicable
only under certain conditions. Subsequently, a number of Federal courts ruled
that various state takeover statutes were unconstitutional insofar as they apply
to corporations incorporated outside the state of enactment.
                                       27
<PAGE>   30

     Based on information supplied by the Company, Purchaser does not believe
that any other state takeover statutes purport to apply to the Offer or the
Merger. Except as discussed above, neither Purchaser nor Parent has currently
complied with any state takeover statute or regulation. Purchaser reserves the
right to challenge the applicability or validity of any state law purportedly
applicable to the Offer or the Merger and nothing in this Offer to Purchase or
any action taken in connection with the Offer or the Merger is intended as a
waiver of such right. If it is asserted that any state takeover statute is
applicable to the Offer or the Merger and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer or the
Merger, Purchaser might be required to file certain information with, or to
receive approvals from, the relevant state authorities, and Purchaser might be
unable to accept for payment or pay for Shares tendered pursuant to the Offer,
or be delayed in consummating the Offer or the Merger. In such case, Purchaser
may not be obligated to accept for payment or pay for any Shares tendered
pursuant to the Offer. See Section 14.

  Other Foreign Approvals

     The Company conducts business in a number of foreign countries and
jurisdictions. In connection with the acquisition of the Shares pursuant to the
Offer, the laws of certain of those foreign countries and jurisdictions may
require the filing of information with, or the obtaining of the approval of,
governmental authorities in such countries and jurisdictions. The governments in
such countries and jurisdictions might attempt to impose additional conditions
on the Company's operations conducted in such countries and jurisdictions as a
result of the acquisition of the Shares pursuant to the Offer. There can be no
assurance that Purchaser will be able to cause the Company or its subsidiaries
to satisfy or comply with such laws or that compliance or non-compliance will
not have adverse consequences for the Company or any subsidiary after purchase
of the Shares pursuant to the Offer.

  Appraisal Rights

     Holders of Shares do not have appraisal rights as a result of the Offer.
However, if the Merger is consummated, holders of Shares at the effective time
of the Merger will have certain rights pursuant to the provisions of Section 262
of the DGCL ("Section 262") to dissent and demand appraisal of their Shares.
Under Section 262, dissenting stockholders who comply with the applicable
statutory procedures will be entitled to receive a judicial determination of the
fair value of their Shares (exclusive of any element of value arising from the
accomplishment or expectation of the Merger) and to receive payment of such fair
value in cash, together with a fair rate of interest, if any. Any such judicial
determination of the fair value of Shares could be based upon factors other
than, or in addition to, the price per Share to be paid in the Merger or the
market value of the Shares. The value so determined could be more or less than
the price per Share to be paid in the Merger.

     THE FOREGOING SUMMARY OF SECTION 262 DOES NOT PURPORT TO BE COMPLETE AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO SECTION 262. FAILURE TO FOLLOW THE
STEPS REQUIRED BY SECTION 262 FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE
LOSS OF THOSE RIGHTS.

  Going Private Transactions

     The Commission has adopted Rule 13e-3 under the Exchange Act, which is
applicable to certain "going private" transactions. Purchaser does not believe
that Rule 13e-3 will be applicable to the Merger because it is anticipated that
the Merger would be effected within one year after the consummation of the Offer
and in the Merger, stockholders would receive the same price per share as in the
Offer. If applicable, Rule 13e-3 requires, among other things, that certain
financial information concerning the fairness of the Merger and the
consideration offered to minority stockholders in such transaction be filed with
the Commission and disclosed to stockholders prior to the consummation of the
Merger.

16. FEES AND EXPENSES

     Purchaser and Parent have retained Georgeson Shareholder Communications,
Inc. to act as the Information Agent and American Stock Transfer & Trust Company
to serve as the Depositary in connection with the Offer. The Information Agent
and the Depositary each will receive reasonable and customary compensation for
their services, be reimbursed for certain reasonable out-of-pocket expenses and
be indemnified against certain liabilities and expenses in connection therewith,
including certain liabilities and expenses under the Federal securities laws.

     Neither Purchaser nor Parent will pay any fees or commissions to any broker
or dealer or other person (other than the Depositary and the Information Agent)
in connection with the solicitation of tenders of Shares pursuant to the Offer.
Brokers, dealers, banks and trust companies will be reimbursed by Purchaser upon
request for customary mailing and handling expenses incurred by them in
forwarding material to their customers.

     Except as set forth above, neither Purchaser nor Parent will pay any fees
or commissions to any broker, dealer or other person or entity in connection
with the solicitation of tenders of Shares pursuant to the Offer. Brokers,
dealers, commercial banks and trust companies will be reimbursed by Purchaser
for customary mailing and handling expenses incurred by them in forwarding Offer
materials to their clients.

17. MISCELLANEOUS

     Parent, Purchaser or an affiliate of Parent may, following the consummation
or termination of the Offer, seek to acquire additional Shares through open
market transactions, privately negotiated transactions, a tender or exchange
offer or otherwise, upon such terms and at such prices as it shall determine,
which may be more than the Offer Price. Each of Parent, Purchaser and their
respective affiliates also reserve the right to dispose of any or all Shares
acquired by them pursuant to the terms of the Merger Agreement.

     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. Neither Purchaser nor Parent is aware of any jurisdiction in which
the making of the Offer or the acceptance thereof would not be in compliance
with the laws of such jurisdiction. To the extent Purchaser or Parent becomes
aware of any state law that would limit the class of offerees in the Offer,
Purchaser will amend the Offer and, depending on the timing of such amendment,
if any, will extend the Offer to provide adequate dissemination of such
information to holders of Shares prior to the expiration of the Offer. In any
jurisdiction the securities, blue sky or other laws of which require the Offer
to be made by a licensed broker or dealer, the Offer shall be deemed to be made
on behalf of Purchaser by one or more registered brokers or dealers licensed
under the laws of such jurisdiction.

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

     Purchaser and Parent have filed with the Commission a Schedule 14D-1
pursuant to Rule 14d-3 under the Exchange Act, together with exhibits,
furnishing certain additional information with respect to the Offer, and may
file amendments thereto. Such Schedule 14D-1 and any amendments thereto,
including exhibits, are available for inspection and copies are obtainable in
the manner set forth in Section 8 of this Offer to Purchase (except that such
material will not be available at the regional offices of the Commission).

LADIES AND GENTLEMEN:

     The undersigned hereby tenders to EDB 4tel Acquisition Corp., a Delaware
corporation ("Purchaser") and a wholly-owned subsidiary of EDB BUSINESS PARTNER
ASA, a Norwegian limited company, the above-described shares of common stock,
par value $0.04 per Share (all of the shares of common stock being hereinafter
collectively referred to as the "Shares" and individually, as a "Share"), of
Telesciences, Inc., a Delaware corporation (the "Company"), at a purchase price
of $8.79 per Share, net to the seller in cash (the "Offer Price"), without
interest thereon, upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated October 25, 1999 (the "Offer to Purchase") and in this
Letter of Transmittal (which together with the Offer to Purchase, constitutes
the "Offer"). The undersigned understands that Purchaser reserves the right to
transfer or assign, in whole at any time, or from time to time in part, to one
or more of its affiliates, the right to purchase all or any portion of the
Shares tendered pursuant to the Offer.

     Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith in accordance with the terms and subject to the conditions of
the Offer (including, if the Offer is extended, amended or supplemented, the
terms and conditions of any such extension, amendment or supplement), the
undersigned hereby sells, assigns and transfers to, or upon the order of,
Purchaser all right, title and interest of the undersigned in and to all of the
Shares that are being tendered hereby and any and all dividends, distributions
(including, without limitation, the issuance of additional Shares pursuant to
stock dividends or stock splits, the issuance of other securities, the issuance
of rights declared, paid or issued with respect to the tendered Shares on or
after October 25, 1999, and payable or for purchase of securities or any cash
dividends) distributable to the undersigned on a date prior to the transfer to
the name of Purchaser (or nominee or transferee of Purchaser) on the Company's
stock transfer records of the Shares tendered herewith (collectively, a
"Distribution"), and irrevocably constitutes and appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Shares (and any Distributions) with full power of substitution (such power
of attorney being deemed to be an irrevocable power coupled with an interest) to
(a) deliver certificates for such Shares (and any Distributions) ("Share
Certificates") or transfer ownership of such Shares (and any Distributions) on
the account books maintained by the Book-Entry Transfer Facility, together in
either case with appropriate evidences of transfer and authenticity, to the
Depositary for the account of Purchaser, (b) present such Shares (and any
Distributions) for transfer on the books of the Company, and (c) receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any Distributions), all in accordance with the terms and subject to
the conditions of the Offer.

     The undersigned hereby irrevocably appoints Purchaser or any other
designees of Purchaser, and each of them, as such stockholder's
attorneys-in-fact and proxies, each with full power of substitution, to the full
extent of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by Purchaser and with respect to any and
all other shares or other securities issued or issuable in respect of such
Shares on or after October 19, 1999. Such appointment will be effective upon the
acceptance for payment of such Shares by Purchaser in accordance with the terms
of the Offer. Upon such acceptance for payment, all prior powers of attorney and
proxies given by such stockholder with respect to such Shares (and such other
shares and securities) will be revoked without further action, and no subsequent
proxies may be given nor any subsequent written consents executed (and, if given
or executed, will not be deemed effective). The proxies (or other designees of
Purchaser) will be empowered to exercise all voting and other rights of such
stockholder as they in their sole discretion may deem proper at any annual or
special meeting of the Company's stockholders or any adjournment or postponement
thereof, by consent in lieu of any such meeting or otherwise. Purchaser reserves
the right to require that, in order for Shares to be deemed validly tendered,
immediately upon Purchaser's payment for such Shares, Purchaser must be able to
exercise full voting rights with respect to such Shares.

     The undersigned hereby represents and warrants that (a) the undersigned has
full power and authority to tender, sell, assign and transfer the Shares (and
any Distributions) tendered hereby, and (b) when the Shares are accepted for
payment by Purchaser, Purchaser will acquire good, marketable and unencumbered
title to the Shares (and all Distributions), free and clear of all liens,
restrictions, charges and encumbrances, and the same will not be subject to any
adverse claim. The undersigned, upon request, will execute and deliver any
signature guarantee or additional documents deemed by the Depositary or
Purchaser to be necessary or
<PAGE>   5

desirable to complete the sale, assignment and transfer of the Shares (and all
Distributions) tendered hereby. In addition, the undersigned shall promptly
remit and transfer to the Depositary for the account of Purchaser any and all
Distributions in respect of the Shares tendered hereby, accompanied by
appropriate documentation of transfer, and pending such remittance or
appropriate assurance thereof, Purchaser will be, subject to applicable law,
entitled to all rights and privileges as owner of any such Distribution and may
withhold the entire purchase price or deduct from the purchase price the amount
or value thereof, as determined by Purchaser in its sole discretion.

     All authority herein conferred or agreed to be conferred shall survive the
death, incapacity, liquidation or dissolution of the undersigned and any
obligations of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, trustees in bankruptcy, personal and legal
representatives, successors and assigns of the undersigned. Except as stated in
the Offer to Purchase this tender of Shares is irrevocable.

     The undersigned understands that tenders of Shares pursuant to any of the
procedures described in Section 2 of the Offer to Purchase and in the
instructions hereto will constitute a binding agreement between the undersigned
and Purchaser upon the terms and subject to the conditions set forth in the
Offer, including the undersigned's representation and warranty that the
undersigned owns the Shares tendered hereby.

     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the Offer Price of all Shares purchased, and/or
return any Share Certificates not tendered or not accepted for payment in the
name(s) of the registered holder(s) appearing under "Description of Shares
Tendered." Similarly, unless otherwise indicated herein under "Special Delivery
Instructions," please mail the check for the Offer Price and/or return any Share
Certificates not tendered or not accepted for payment (and accompanying
documents, as appropriate) to the address(es) of the registered holder(s)
appearing under "Description of Shares Tendered." In the event that both the
"Special Delivery Instructions" and the "Special Payment Instructions" are
completed, please issue the check for the Offer Price of any Shares purchased
and/or return any Share Certificates not tendered or accepted for payment and
any accompanying documents, as appropriate in the name(s) of, and deliver such
check and/or return any such Share Certificates (and any accompanying documents)
to, the person(s) so indicated. Unless otherwise indicated herein under "Special
Payment Instructions," please credit any Shares tendered herewith by book-entry
transfer that are not accepted for payment by crediting the account designated
above. The undersigned recognizes that Purchaser has no obligation, pursuant to
the "Special Payment Instructions," to transfer any Shares from the name(s) of
the registered holder(s) thereof if Purchaser does not accept for payment any of
the Shares so tendered.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

     1. GUARANTEE OF SIGNATURES.  No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) of Shares (which term, for purposes of this document, shall
include any participant in the Book-Entry Transfer Facility whose name appears
on a security position listing as the owner of Shares) tendered herewith, unless
such holder(s) has completed either the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" above, or (b)
if such Shares are tendered for the account of a firm which is a bank, broker,
dealer, credit union, savings association or other entity which is a member in
good standing of the Securities Transfer Association Medallion Program, the New
York Stock Exchange, Inc., Medallion Signature Program or the Stock Exchange
Medallion Program (each of the foregoing being referred to as an "Eligible
Institution"). In all other cases, all signatures on this Letter of Transmittal
must be guaranteed by an Eligible Institution. See Instruction 5 of this Letter
of Transmittal.

     2. REQUIREMENTS OF TENDER.  This Letter of Transmittal is to be completed
by stockholders either if certificates are to be forwarded herewith or, unless
an Agent's Message is utilized, if tenders are to be made pursuant to the
procedure for tender by book-entry transfer set forth in Section 2 of the Offer
to Purchase. Certificates for all physically tendered Shares or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at the Book-Entry Transfer Facility,
together with a properly completed and duly executed Letter of Transmittal (or a
facsimile hereof), with any required signature guarantees, or an Agent's Message
in connection with a book-entry transfer, and any other documents required by
this Letter of Transmittal, must be received by the Depositary at its address
set forth herein on or prior to the Expiration Date (as defined in Section 1 of
the Offer to Purchase). If certificates for Shares are forwarded to the
Depositary in multiple deliveries, a properly completed and duly executed Letter
of Transmittal must accompany each such delivery.

     Stockholders whose Share Certificates are not immediately available or who
cannot deliver their Share Certificates and all other required documents to the
Depositary prior to the Expiration Date or who cannot complete the procedure for
delivery by book-entry transfer on a timely basis may tender their Shares by
properly completing and duly executing a Notice of Guaranteed Delivery pursuant
to the guaranteed delivery procedure set forth in Section 2 of the Offer to
Purchase. Pursuant to such procedure: (i) such tender must be made by or through
an Eligible Institution; (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form made available by Purchaser, must
be received by the Depositary on or prior to the Expiration Date; and (iii) the
Share Certificates (or a Book-Entry Confirmation) representing all tendered
Shares, in proper form for transfer, in each case together with the Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed, with
any required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by this Letter of Transmittal,
must be received by the Depositary within three Nasdaq Stock Market trading days
after the date of execution of such Notice of Guaranteed Delivery. A "Nasdaq
Stock Market trading day" is any day in which the Nasdaq Stock Market, Inc.'s
Nasdaq SmallCap Market is open for business. If Share Certificates are forwarded
separately to the Depositary a properly completed and duly executed Letter of
Transmittal must accompany such delivery.

     Tendering stockholders should use this Letter of Transmittal (and, if
necessary, the Notice of Guaranteed Delivery provided with the Offer to
Purchase). Stockholders will be able to tender (or withdraw) their Shares
pursuant to the Offer until 12:00 midnight, New York City time, Monday, November
22, 1999 (or such later date to which the Offer may be extended).

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH
<PAGE>   9

RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution of
this Letter of Transmittal (or a facsimile hereof), waive any right to receive
any notice of the acceptance of their Shares for payment.

     3. INADEQUATE SPACE AND THE NUMBER OF SHARES TENDERED.  If the space
provided herein under "Description of Shares Tendered" is inadequate, the
certificate numbers and/or the number of Shares evidenced by such Share
Certificates and any other required information should be listed on a separate
signed schedule attached hereto.

     4. PARTIAL TENDER.(NOT APPLICABLE TO STOCKHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  If fewer than all the Shares evidenced by any Share Certificate
delivered to the Depositary herewith are to be tendered, fill in the number of
Shares which are to be tendered in the box entitled "Number of Shares Tendered."
In such cases, new certificates for the Shares that were evidenced by your old
Share Certificates, but which were not tendered by you, will be sent to you,
unless otherwise provided in the appropriate box on this Letter of Transmittal
entitled "Special Delivery Instructions", as soon as practicable after the
Expiration Date. All Shares represented by certificates delivered to the
Depositary will be deemed to have been tendered unless otherwise indicated.

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

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

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

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

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

     If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Share Certificate(s) listed, the Share Certificate(s)
must be endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name(s) of the registered holder(s) appear on the
certificate(s). Signatures on such Share Certificates and stock powers must be
guaranteed by an Eligible Institution, unless the signature is that of an
Eligible Institution.

     6. STOCK TRANSFER TAXES.  Except as otherwise provided in this Instruction
6, Purchaser will pay any stock transfer taxes with respect to the purchase of
Shares pursuant to the Offer. If, however, payment of the Offer Price of any
Shares purchased is to be made to, or if certificate(s) evidencing Shares not
tendered or purchased are to be registered in the name of, any person other than
the registered owner(s), or if tendered Share Certificate(s) are registered in
the name of any person other than the person(s) signing this Letter of
Transmittal, the amount of any stock transfer taxes (whether imposed on the
registered owner(s) or such person) payable on account of the transfer to such
person will be deducted from the purchase price of such Shares unless
satisfactory evidence of the payment of such taxes, or an exemption therefrom,
is submitted.
<PAGE>   10

     7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check for the Offer
Price of any Shares tendered hereby is to be issued in the name of, and/or Share
Certificates for Shares not tendered or not purchased are to be issued or
returned to, a person other than the signer of this Letter of Transmittal or if
a check and/or such certificates are to be returned to a person other than the
person(s) signing this Letter of Transmittal or to an address other than that
shown in this Letter of Transmittal in the box entitled "Description of Shares
Tendered", the appropriate boxes on this Letter of Transmittal must be
completed. A stockholder who tenders by book-entry transfer may request that
Shares not accepted for payment be credited to such account maintained at the
Book-Entry Transfer Facility as such stockholder may designate under "Special
Payment Instructions." If no such instructions are given, such Shares not
accepted for payment will be returned by crediting the account designated above
under "Description of Shares Tendered."

     8. WAIVER OF CONDITIONS.  The conditions of the Offer may be waived by
Purchaser in whole or in part at any time and from time to time in its sole
discretion, subject to the terms of the Agreement and Plan of Merger dated as of
October 19, 1999, among Telesciences, Inc., EDB 4tel Acquisition Corp. and EDB
Business Partner ASA.

     9. BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. federal income tax
law, a stockholder, whose tendered Shares are accepted for payment, is required
to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN"), generally the stockholder's social security or
federal employer identification number, and certain other information, on
Substitute Form W-9 below. If the Depositary is not provided with the correct
TIN, or an adequate basis for exemption, the Internal Revenue Service may
subject the stockholder or other payee to a $50 penalty. In addition, payments
that are made to such stockholder or other payee with respect to Shares
purchased pursuant to the Offer may be subject to 31% backup withholding.

     Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.

     If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the stockholder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.

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

     To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of such stockholder's correct TIN by
completing a Substitute Form W-9 certifying (a) that the TIN provided on
Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN), and
(b) that (1) such stockholder is exempt from backup withholding or (2) such
stockholder has not been notified by the Internal Revenue Service that such
stockholder is subject to backup withholding as a result of a failure to report
all interest or dividends or (3) the Internal Revenue Service has notified such
stockholder that such stockholder is no longer subject to backup withholding.
Exempt holders (including, among others, all corporations and certain foreign
individuals) are not subject to these backup withholding and reporting
requirements. To prevent possible erroneous backup withholding, an exempt holder
must enter its correct TIN in Part 1 of Substitute Form W-9, write "Exempt" in
Part 2 of such form, and sign and date the form. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9
Guidelines") for
<PAGE>   11

additional instructions. In order for a nonresident alien or foreign entity to
qualify as exempt, such person must submit a completed Form W-8, "Certificate of
Foreign Status" signed under the penalties of perjury attesting to such exempt
status. Such forms may be obtained from the Depositary.

     The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which number to report.

     10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions or requests

telephone numbers set forth below. Additional copies of the Offer to Purchase,
this Letter of Transmittal and the Notice of Guaranteed Delivery may also be

or trust companies.

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

     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF), TOGETHER

     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates

     If a holder of Shares wishes to tender Shares, but such stockholders' Share
Certificates are not immediately available or such stockholder cannot deliver

     Purchaser will not pay any fees or commissions to any broker, dealer or
other person (other than the Depositary and the Information Agent as described

to the Offer. However, Purchaser will reimburse you for customary mailing and
handling expenses incurred by you in forwarding any of the enclosed materials to

          3. The Purchaser, the Parent and the Company have entered into an
     Agreement and Plan of Merger dated October 19, 1999 (the "Merger
     Agreement"). The Board of Directors of the Company has approved the terms
     of the Merger Agreement, including the Offer and the Merger (as defined in
     the Offer to Purchase), and has determined that the terms of the Offer and
     the Merger are advisable, fair to, and in the best interests of
     stockholders of the Company, and recommends that the stockholders of the
     Company accept the Offer and tender their Shares pursuant to the Offer.

<PAGE>   2

          5. The Offer is conditioned upon, among other things, there being
     validly tendered and not withdrawn prior to the expiration of the Offer
     that number of shares which when added to the Shares then beneficially
     owned by Parent represent at least a majority of the total number of then
     outstanding Shares on the date Shares are accepted for payment. The Offer
     is also subject to the conditions set forth in the Offer to Purchase (see
     the Introduction Section and Sections 12 and 14 of the Offer to Purchase).

          6. Tendering stockholders will not be obligated to pay brokerage fees
     or commissions or, except as otherwise provided in Instruction 6 of the
     Letter of Transmittal, stock transfer taxes with respect to the purchase of
     Shares by Purchaser pursuant to the Offer. However, federal income tax
     withholding at a rate of 31% may be required, unless an exemption is
     provided or unless the required taxpayer identification information is
     provided. See Instruction 9 of Letter of Transmittal.

          7. Notwithstanding any other provision of the Offer, payment for
     Shares accepted for payment pursuant to the Offer will in all cases be made
     only after timely receipt by the Depositary of (a) certificates for Shares
     or a timely Book-Entry Confirmation (as defined in the Offer to Purchase)
     with respect to such Shares pursuant to the procedures set forth in Section
     2 of the Offer to Purchase, (b) the Letter of Transmittal (or a manually
     signed facsimile thereof), properly completed and duly executed, together
     with any required signature guarantees, or, in the case of book-entry
     transfers, an Agent's Message (as defined in the Offer to Purchase), and
     (c) any other documents required by the Letter of Transmittal. Accordingly,
     payment may not be made to all tendering stockholders at the same time
     depending upon when certificates for or confirmations of book-entry
     transfer of such Shares are actually received by the Depositary.

EXEMPT PAYEES DESCRIBED ABOVE SHOULD FILE FORM W-9 TO AVOID POSSIBLE ERRONEOUS
BACKUP WITHHOLDING. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO
SIGN AND DATE THE FORM.

  Certain payments other than interest, dividends, and patronage dividends, that
are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under Sections 6041, 6041A(a),
6045, and 6050A.

  PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividends,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. The IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Beginning January 1, 1993, payers must generally
withhold 31% of taxable interest, dividends, and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your correct taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS. -- If you fail to
include any portion of an includable payment for interest, dividends, or
patrionage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE STATEMENTS WITH RESPECT TO WITHHOLDING. -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- If you falsify
certifications or affirmations, you are subject to criminal penalties including
fines and/or imprisonment.

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

                           EDB 4TEL ACQUISITION CORP.

                          A WHOLLY OWNED SUBSIDIARY OF

                            EDB BUSINESS PARTNER ASA

         EDB 4tel Acquisition Corp., a Delaware corporation ("Purchaser") and a
wholly owned subsidiary of EDB Business Partner ASA, a Norwegian limited company
("EDB"), is offering to purchase all outstanding shares of common stock, $.04
par value (the "Shares"), of Telesciences, Inc., a Delaware corporation (the
"Company"), at $8.79 per Share (the "Offer Price"), net to the seller in cash,
upon the terms and subject to the conditions set forth in the Offer to Purchase
dated October 25, 1999, and in the related Letter of Transmittal (which,
together with any amendments or supplements thereto, collectively constitute the
"Offer").

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
TIME, ON MONDAY, NOVEMBER 22, 1999, UNLESS EXTENDED. SHARES WHICH ARE TENDERED
PURSUANT TO THE OFFER MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION DATE.

         The Offer is conditioned upon, among other things, the satisfaction or
waiver of certain conditions to the obligations of Purchaser, EDB and the
Company, including there being validly tendered and not withdrawn prior to the
expiration of the Offer, such number of Shares that would constitute at least a
majority of the then outstanding Shares (the "Minimum Condition"). The Offer is
not conditioned on obtaining financing.

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of October 19, 1999 (the "Merger Agreement"), among EDB, Purchaser and
the Company pursuant to which, following the







<PAGE>   2



consummation of the Offer, Purchaser will be merged with and into the Company
and the Company will become a wholly owned subsidiary of EDB (the "Merger"). On
the effective date of the Merger, each outstanding Share (except for Shares held
by Purchaser, EDB or their subsidiaries or by stockholders exercising their
appraisal rights under the Delaware General Corporation Law) will be converted
into the right to receive the Offer Price net in cash (or any greater amount per
Share paid pursuant to the Offer), without interest. EDB and Purchaser have
entered into shareholder agreements (the "Shareholder Agreements") with two
stockholders of the Company (the "Agreeing Stockholders") holding in the
aggregate 198,597 Shares, representing approximately 19% of the issued and
outstanding Shares. Pursuant to these agreements, each Agreeing Stockholder has
agreed, provided the Merger Agreement has not been terminated, or the Purchaser
has not notified the Agreeing Stockholder of its intent to continue the Offer or
a revised Offer within 2 business days after termination of the Merger
Agreement, to (i) tender to Purchaser all Shares beneficially owned by such
Agreeing Stockholder, (ii) vote all Shares in favor of approval of the Merger
Agreement and the transactions contemplated thereby and (iii) oppose any
Alternative Acquisition (as defined in the Merger Agreement) and to vote all
Shares now or hereafter owned by such Stockholder, or execute a consent or
proxy, against any Alternative Acquisition.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE MERGER AGREEMENT
AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER,
AND DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE AT A PRICE AND ON
TERMS THAT ARE ADVISABLE AND FAIR TO, AND IN THE BEST INTERESTS OF, STOCKHOLDERS
OF THE COMPANY AND RESOLVED TO RECOMMEND THAT STOCKHOLDERS OF THE COMPANY ACCEPT
THE OFFER AND TENDER THEIR SHARES.

         For purposes of the Offer, Purchaser shall be deemed to have accepted
for payment, and thereby purchased, Shares validly tendered to Purchaser and not
property withdrawn when, as and if Purchaser gives oral or written notice to
American Stock Transfer & Trust Company, as Depositary (the "Depositary") of its
acceptance of such Shares for payment. Upon the terms and subject to the
conditions of the Offer, payment for Shares accepted for payment pursuant to the
Offer will be made by deposit of the purchase price with the Depositary, which
will act as agent for the tendering stockholders for the purpose of receiving
payments from Purchaser and transmitting such payments to tendering stockholders
whose shares have been accepted for payment. In all cases, payment for Shares
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) certificates for such Shares (or of a confirmation of a
book-entry transfer of such Shares into the Depositary's account at the
Book-Entry Transfer Facility (as defined in Section 2 of the Offer to
Purchase)), (ii) a properly completed and duly executed Letter of Transmittal
(or facsimile thereof) with any required guaranteed signature or, in the case of
a book-entry transfer, an Agent's Message (as defined in the Offer to Purchase)
and (iii) any other documents required by the Letter of Transmittal. For a
description of the procedure for tendering Shares pursuant to the Offer, see
Section 2 of the Offer to Purchase. Accordingly, payment may be made to
tendering stockholders at different times if delivery of the Shares and other
required documents occur at different times. Under no circumstances will
interest be paid by Purchaser on the consideration paid for Shares pursuant to
the Offer, regardless of any delay in making such payment.

         The term "Expiration Date" means 12:00 midnight, New York City time, on
Monday, November 22, 1999, unless and until Purchaser (subject to the Merger
Agreement) extends the period of time during which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date on which
the Offer, as so extended by Purchaser, shall expire subject to the terms of the
Merger Agreement and to applicable rules and regulations of the Securities and
Exchange Commission. Provided that the Merger Agreement shall not have been
terminated in accordance with its terms, if the conditions set forth in Annex A
of the Merger Agreement are not satisfied or, to the extent permitted thereby,
waived by Purchaser as of the date the Offer would otherwise have expired, then,
except to the extent that such conditions are incapable of being satisfied,
Purchaser will extend the Offer from time to time until the earlier of the
consummation of the Offer or the date which is twenty (20) business days from
the original Expiration Date. Pursuant to the terms of the Merger Agreement,
Purchaser shall be entitled to extend the Offer one or more times beyond the
Expiration Date for an aggregate period of up to ten (10) business days if on
the Expiration Date, the conditions to the Offer set forth in Annex A of the
Merger Agreement have been satisfied or waived, but


                                        2


<PAGE>   3



there shall not have been tendered that number of Shares which would equal at
least ninety percent (90%) of the issued and then outstanding Shares. Any such
extension will be followed by a public announcement thereof no later than 9:00
a.m., New York City Time, on the next business day after the previously
scheduled expiration of the Offer. During any such extension, all Shares
previously tendered and not withdrawn will remain tendered, subject to the right
of a tendering stockholder to withdraw such stockholder's Shares.

         Pursuant to the Merger Agreement, no change or waiver may be made,
without the prior written consent of the Company, except as permitted by the
Merger Agreement, that (i) decreases the Offer Price, (ii) decreases the number
of Shares to be purchased in the Offer, (iii) changes the form of consideration
payable in the Offer, (iv) adds to or changes the conditions to the Offer set
forth in Section 15 of the Offer to Purchase, (v) waives the Minimum Condition
or (vi) changes any other terms or conditions of the Offer.

         Except as otherwise provided below, tenders of Shares made pursuant to
the Offer are irrevocable. Shares tendered pursuant to the Offer may be
withdrawn at any time on or prior to the Expiration Date and, unless theretofore
accepted for payment pursuant to the Offer, may also be withdrawn at any time
after December 23, 1999. For a withdrawal to be effective, a written, telex,
telegraphic or facsimile transmission notice of withdrawal must be timely
received by the Depositary at its address set forth on the back cover of the
Offer to Purchase and must specify the name of the person having tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder of the Shares to be withdrawn, if different from the name of
the person who tendered the Shares. If Certificates for the Shares to be
withdrawn have been delivered to the Depositary, a signed notice of withdrawal,

of Shares may not be rescinded, and Shares properly withdrawn will thereafter be
deemed not validly tendered for purposes of the Offer. However, withdrawn Shares
may be retendered at any time prior to the Expiration Date by following one of
the procedures described in Section 2 of the Offer to Purchase. All questions as
to the form and validity (including time of receipt) of notices of withdrawal
will be determined by Purchaser, in its sole discretion, whose determination
will be final and binding on all parties.

relevant materials will be mailed to record holders of Shares and furnished to
brokers, dealers, banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the Company's stockholder list or, if
applicable, who are listed as participants in a clearing agency's security
position listing, for subsequent transmittal to beneficial owners of Shares.

the Securities Exchange Act of 1934, as amended, is contained in the Offer to
Purchase and is incorporated herein by reference.

announced that it has signed a definitive merger agreement, valued at $13.65
million with the Norwegian telecom company EDB BUSINESS PARTNER ASA.

1999) and will commence within five business days. The full $13.65 million is to
be placed into escrow this week.

The tender offer is scheduled to expire twenty business days after commencement,
unless extended, and is subject to customary terms and conditions. The Board of
Directors of both companies have approved the transaction. The tender offer for
shares of Telesciences' common stock will be made only through definitive tender
offer documents, which will be filed with the Securities and Exchange Commission
and mailed to the stockholders of Telesciences.

Telesciences not purchased in the initial tender offer (other than shares held
by EDB or its affiliates or dissenting stockholders) will be converted into the
right to receive $8.79 per share in cash.

         AGREEMENT AND PLAN OF MERGER, dated as of October 19, 1999 (the
"Agreement"), by and among Telesciences, Inc., a Delaware corporation (the
"Company"), EDB Business Partner ASA, a Norwegian public limited company
("Parent"), and EDB 4Tel Acquisition Corp., a Delaware corporation and a wholly
owned subsidiary of Parent ("Purchaser").

                             W I T N E S S E T H :

         WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
deem it advisable and in the best interests of the respective stockholders of
such corporations to effect the merger of the Purchaser with and into the
Company (the "Merger") upon the terms and subject to the conditions set forth
herein; and

         WHEREAS, the respective Boards of Directors of Parent, Purchaser and
the Company have approved the acquisition of the Company by Parent and, in
furtherance of such acquisition, Parent proposes to cause Purchaser to make a
cash tender offer for all of the issued and outstanding shares of Common Stock,
par value $.04 per share (the "Common Stock"), of the Company, on the terms
specified herein and the Board of Directors of the Company has approved the
tender offer and intends to recommend that it be accepted by the stockholders

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements hereinafter contained and
intending to be bound hereby, the parties hereto agree as follows:

                                   ARTICLE I
                                   THE OFFER

         SECTION 1.01 The Offer.

                  (a) Provided that this Agreement shall not have been
         terminated in accordance with Section 8.01 and nothing shall have
         occurred that would render any of the conditions set forth in Annex A
         hereto incapable of being satisfied, as promptly as practicable (but
         in no event later that five (5) business days after the date of this
         Agreement), Purchaser shall commence (within the meaning of Rule 14d-2
         under the Securities Exchange Act of 1934, as amended (the "Exchange
         Act")) an offer to purchase for cash (the "Offer") any and all of the
         issued and outstanding shares of Common Stock (the "Shares") at a
         price of $8.79 per Share, net to the seller in cash, without interest.
         For purposes of this Agreement, the term "Transaction Consideration"
         shall mean $8.79 per Share in cash or any higher price as shall be
         paid in respect of the Shares in the Offer. The obligations of
         Purchaser to commence the Offer and to accept for payment and to pay
         for any Shares tendered shall be subject to only the conditions set
         forth in Annex A hereto (any or all of which may, subject to the
         provisions hereof, be waived by Parent or Purchaser, subject to
         applicable law). Without the prior written consent of the Company,
         Purchaser shall not (i) decrease the Transaction Consideration with
         respect to any Shares, (ii) decrease the number of Shares to be
         purchased in the Offer, (iii) change the form of consideration payable
         in the Offer, (iv) add to or change the conditions to the Offer set
         forth in Annex A, (v) waive the Minimum Condition (as defined in Annex
         A) or (vi) make any other change in the terms or conditions of the
         Offer. Parent and Purchaser expressly reserve the right to waive any
         condition (other than the Minimum Condition) specified in Annex A or
         to increase the Transaction Consideration. Provided that this
         Agreement shall not have been terminated in accordance with Article
         VIII hereof, if the conditions set forth in Annex A are not satisfied
         or, to the extent permitted hereby, waived by Purchaser as of the date
         the Offer would otherwise have expired, then, except to the extent
         that such conditions are incapable of being satisfied, Purchaser will
         extend the Offer from time to time until the earlier of the
         consummation of the Offer or the date which is twenty (20) business
         days from the original expiration date of the Offer (such date, the
         "Final Date"). Purchaser shall, subject to the terms and conditions of
         the Offer, accept for payment Shares validly tendered and not
         withdrawn as soon as it is legally permitted to do so under applicable
         law; provided, however, that Purchaser shall be entitled to extend the
         Offer one or more times beyond the Final Date for an aggregate period
         of up to ten (10) business days if on the Final Date the conditions to
         the Offer set forth in Annex A have been satisfied or waived but there
         shall not have been tendered that number of Shares which would equal
         at least ninety percent (90%) of the issued and then outstanding
         Shares. Purchaser shall be obligated to consummate the Offer
         immediately upon reaching such ninety percent (90%) threshold. Such
         extended date shall then be the Final Date for purposes of this
         Agreement. The Company agrees that it will not tender, and will not
         permit any of its subsidiaries to tender, any Shares held by it or any
         such subsidiary pursuant to the Offer.

                  (b) Purchaser shall deposit with First Union National Bank
         (the "Escrow Agent") a sufficient amount of funds (the "Escrowed
         Funds") necessary to (i) make the cash payments contemplated by
         Section 1.01(a) to purchase all of the Shares tendered in the Offer,
         (ii) make the cash payments contemplated by Section 2.08 with respect
         to the settlement of the Options (as defined in Section 2.08), and
         (iii) redeem the outstanding shares of Series A Preferred Stock of the
         Company (the "Series A Preferred Shares") for cash in accordance with
         the terms of the Certificate of Designation of Preferences and Rights
         of the Series A Preferred Stock (the "Certificate of Designation"). A
         calculation of this amount is attached hereto as Annex C. The Escrowed
         Funds shall be deposited with the Escrow Agent pursuant to, and shall
         be held, applied, invested, reinvested, and disbursed in accordance
         with, an escrow agreement among the Company, the Parent, the Purchaser
         and the Escrow Agent substantially in the form of Annex B attached
         hereto (the "Escrow Agreement"). Unless otherwise provided in the
         Escrow Agreement, said deposit shall be made by wire transfer of
         immediately available funds pursuant to wire transfer instructions set
         forth in the Escrow Agreement. Purchaser shall use its reasonable
         efforts to initiate such wire transfer on Tuesday, October 19, 1999
         and complete such wire transfer as soon as practical thereafter, but
         in no event later than Friday, October 22, 1999.

                  (c) Within five (5) business days after the public
         announcement of the execution of this Agreement, Parent and Purchaser
         shall file with the United States Securities and Exchange Commission
         (the "SEC") and the National Association of Securities Dealers, Inc.
         ("NASD"), if applicable, a Tender Offer Statement on Schedule 14D-1
         (together with all amendments and supplements thereto and including
         the exhibits thereto, the "Schedule 14D-1") with respect to the Offer.
         The Schedule 14D-1 will include, as exhibits, the Offer to Purchase
         and a form of letter of transmittal (collectively, the "Offer
         Documents"). Parent and Purchaser agree that the Schedule 14D-1 and
         the Offer Documents will comply as to form and content in all material
         respects with the applicable provisions of the federal securities
         laws. The Company will cooperate fully in the preparation of the
         Schedule 14D-1 prior to its being filed with the SEC. The Company and
         its counsel shall be given an opportunity to review and comment upon
         the Schedule 14D-1 and the Offer Documents and any amendment or
         supplement thereto prior to the filing thereof with the SEC, and
         Parent and Purchaser shall consider such comments in good faith.
         Parent and Purchaser agree to provide to the Company and its counsel
         any comments which Parent, Purchaser or their counsel may receive from
         the Staff of the SEC promptly after receipt thereof, and any proposed
         responses thereto, with respect to the Schedule 14D-1 or the Offer
         Documents and any amendment or supplement thereto. Parent, Purchaser
         and the Company agree to correct promptly any information provided by
         any of them for use in the Schedule 14D-1 or the Offer Documents which
         shall have become false or misleading in any material respect, and
         Parent and Purchaser further agree to take all steps reasonably
         necessary to cause the Schedule 14D-1 as so corrected to be filed with
         the SEC and to disseminate any revised Offer Documents to the
         Company's stockholders, in each case as and to the extent required by
         the applicable provisions of the federal securities laws.

                  (d) Contemporaneously with the purchase by Purchaser of at
         least a majority of the Shares pursuant to the Offer (the "Completion
         of the Offer"), Purchaser shall cause the Company to redeem the Series
         A Preferred Shares for cash in accordance with the terms of the
         Certificate of Designation, and shall cause the funds to be used for
         such redemption to be transferred from the Escrowed Funds to the
         Company.

         SECTION 1.02 Company Actions; Rights. The Company hereby consents to
the Offer and represents that (a) its Board of Directors (at a meeting duly
called and held) has (i) determined that each of the Offer and the Merger is
advisable and fair to and in the best interests of the stockholders of the
Company, (ii) approved and adopted this Agreement and the transactions
contemplated hereby, including the Merger, and (iii) resolved to recommend
acceptance of the Offer and approval and adoption of this Agreement and the
transactions contemplated hereby, including the Merger, by the stockholders of
the Company and (b) Brooks, Houghton & Company, Inc. ("BHC") has delivered to
the Company's Board of Directors its oral opinion (to be confirmed in writing
no later than the date of the filing of the Schedule 14D-1, which opinion
Parent and Purchaser shall be entitled to include as an exhibit to the Schedule
14D-1), that the cash consideration to be received by the holders of the Common
Stock in the Offer and the Merger is fair to such stockholders from a financial
point of view. The Company hereby agrees to file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
and shall use reasonable efforts to file the Schedule 14D-9 as soon as
practicable after the Offer is commenced but no later than ten (10) business
days after the date this Agreement is announced, which shall, subject to the
provisions of Section 6.02 of this Agreement, contain such recommendation.

         The Parent, Purchaser and their counsel shall be given an opportunity
to review and comment upon the Schedule 14D-9 and any amendment or supplement
thereto prior to the filing thereof with the SEC, and the Company shall
consider such comments in good faith. The Company agrees to provide to the
Parent, Purchaser and their counsel any comments which the Company or its
counsel may receive from the staff of the SEC promptly after receipt thereof,
and any proposed responses thereto, with respect to the Schedule 14D-9 and any
amendment or supplement thereto. Parent, Purchaser and the Company agree to
correct promptly any information provided by any of them for use in the
Schedule 14D-9 which shall have become false or misleading in any material
respect, and the Company further agrees to take all steps necessary to cause
the Schedule 14D-9 as so corrected to be filed with the SEC and to disseminate
any revised Schedule 14D-9 to the Company's stockholders, in each case as and
to the extent required by the applicable provisions of the federal securities
laws. Company agrees to make reasonable efforts to include Parent, Purchaser
and their counsel in any substantive oral communications with the SEC with
respect to the Schedule 14D-9. In connection with the Offer, provided that this
Agreement shall not have been terminated in accordance with Article VIII
hereof, the Company will promptly furnish Purchaser with mailing labels,
security position listings and any available listing or computer file




                                       4
<PAGE>   8

containing the names and addresses of the record holders of the Shares as of a
recent date, and shall furnish Purchaser with such information and assistance
as Purchaser or its agents may reasonably request in communicating the Offer to
the stockholders of the Company. Subject to the requirements of law, and except
for such steps as are necessary to disseminate the Schedule 14D-1, Parent and
Purchaser shall hold in confidence the information contained in any of such
labels and lists and the additional information referred to in the preceding
sentence, will use such information only in connection with the Offer and, if
this Agreement is terminated, will upon request deliver to the Company all
copies of such information then in their possession.



         SECTION 1.03 Board of Directors and Committees; Section 14(f).

                  (a) Subject to the requirements of applicable law, promptly
         upon the purchase of not less than a majority of the outstanding
         shares by Purchaser of Shares pursuant to the Offer and from time to
         time thereafter, subject to paragraph (c) of this Section 1.03,
         Purchaser shall be entitled to designate up to such number of
         directors, rounded up to the next whole number plus one, on the Board
         of Directors of the Company (the "Board") as will give Purchaser
         representation on the Board equal to the product of the total number
         of directors on the Board, after giving effect to such representation,
         and the percentage that such number of Shares so purchased bears to
         the total number of issued and outstanding Shares, and the Company
         shall use its reasonable efforts to, upon request by Purchaser,
         promptly, at the Company's election, either increase the size of the
         Board or secure the resignation of such number of directors as is
         necessary to enable Purchaser's designees to be elected to the Board
         and shall cause Purchaser's designees to be so elected, but in no
         event less than a majority of directors. At such times the Company
         will use its reasonable efforts to cause individuals designated by
         Purchaser to constitute the same percentage as is on the Board of (i)
         each committee of the Board (other than any committee of the
         Independent Directors), (ii) each board of directors of each
         subsidiary of the Company designated by Purchaser and (iii) each
         committee of each such board.

                  (b) The Company's obligations to appoint designees to the
         Board shall be subject to Section 14(f) of the Exchange Act and Rule
         14f-1 promulgated thereunder. The Company shall promptly take all
         actions required pursuant to Section 14(f) and Rule 14f-1 in order to
         fulfill its obligations under this Section 1.03 and shall include in
         the Schedule 14D-9 such information with respect to the Company and
         its officers and directors as is required under Section 14(f) and Rule
         14f-1. Parent or Purchaser will supply to the Company in writing and
         be solely responsible for any information with respect to any of them
         and their nominees, officers, directors and affiliates required by
         Section 14(f) and Rule 14f-1.

                  (c) After the time that Purchaser's designees constitute at
         least a majority of the Board and until the Effective Time, the Board
         shall always have at least two members (the "Independent Directors")




                                       5
<PAGE>   9

         who are neither officers of Parent nor designees, shareholders or
         affiliates of Parent or Parent's affiliates. During such period, any
         (i) amendment or termination of this Agreement, (ii) extension of time
         for the performance or waiver of the obligations or other acts of
         Parent or Purchaser or waiver of the Company's rights hereunder or
         (iii) action by the Company with respect to this Agreement and the
         transactions contemplated hereby which adversely affects the interests
         of the stockholders of the Company, shall require the approval of a
         majority of the Independent Directors in addition to any required
         approval thereof by the full Board. If the number of Independent
         Directors shall be reduced below two for any reason whatsoever, any
         remaining Independent Director shall be entitled to designate a person
         to fill the vacancy, which designee shall not be a current or former
         officer or affiliate of Parent or any of Parent's affiliates, or, if
         no Independent Directors then remain, the other directors shall
         designate two persons to fill such vacancies who shall not be current
         or former officers or affiliates of Parent or any of Parent's
         affiliates, and such persons shall be deemed to be Independent
         Directors for purposes of this Agreement. The Board shall not delegate
         any matter set forth in this Section 1.03(c) to any committee of the
         Board.

                  (d) Following the election or appointment of Purchaser's
         designees pursuant to this Section 1.03 and prior to the Effective
         Time, any amendment of this Agreement or the Amended and Restated
         Certificate of Incorporation, as amended, or the Amended and Restated
         By-Laws of the Company, any extension by the Company of the time for
         the performance of any of the obligations or other acts of Parent or
         Purchaser or waiver of any of the Company's rights hereunder, will
         require the concurrence of a majority of the directors of the Company
         then in office who are neither designated by Purchaser, employees of
         the Company or any of its subsidiaries nor otherwise affiliated with
         Purchaser.

                                   ARTICLE II
                                   THE MERGER

         SECTION 2.01 The Merger. Upon the terms and subject to the conditions
hereof, and in accordance with the General Corporation Law of the State of
Delaware (the "DGCL"), Purchaser shall be merged with and into the Company as
soon as practicable following the satisfaction or waiver, if permissible, of
the conditions set forth in Article VII hereof. Following the Merger, the
Company shall continue as the surviving corporation (the "Surviving
Corporation") and the separate corporate existence of Purchaser shall cease.

         SECTION 2.02 Effective Time. The Merger shall be consummated, as and
when provided in Section 2.12 hereof, by filing with the Secretary of State of
the State of Delaware a certificate of merger in such form as is required by,
and executed in accordance with, the relevant provisions of the DGCL (the time
of such filing being the "Effective Time").

         SECTION 2.03 Effects of the Merger. The Merger shall have the effects
set forth in Section 259 of the DGCL and from and after the Effective Time, the
Surviving Corporation shall possess all the rights, privileges, powers and
franchises and be subject to all of the restrictions, disabilities, liabilities




                                       6
<PAGE>   10

and duties of the Company and Purchaser. In particular, the Surviving
Corporation, as of the Effective Time, hereby expressly assumes any and all
financial obligations of the Company under the Credit Facility. As of the
Effective Time, the Company shall be a wholly owned subsidiary of Parent.

         SECTION 2.04 Certificate of Incorporation and By-Laws. The Amended and
Restated Certificate of Incorporation, as amended, and the Amended and Restated
By-Laws of the Purchaser shall be the Certificate of Incorporation and By-Laws
of the Surviving Corporation until thereafter changed or amended as provided
therein or by law.

         SECTION 2.05 Directors. The directors of Purchaser immediately prior
to the Effective Time shall constitute the Board of Directors of the Surviving
Corporation until their respective successors are duly elected and qualified.

         SECTION 2.06 Officers. The officers of the Purchaser immediately prior
to the Effective Time shall be the officers of the Surviving Corporation until
their respective successors are duly elected and qualified.

         SECTION 2.07 Conversion of Shares. Each Share issued and outstanding
immediately prior to the Effective Time (other than Shares held by Parent, the
Company or any subsidiary of Parent or of the Company, which shall be canceled,
and Dissenting Shares (as hereinafter defined)) shall, by virtue of the Merger
and without any action on the part of the holder thereof, be converted into the
right to receive the Transaction Consideration in respect of such Shares in
cash, payable to the holder thereof, without interest thereon, upon surrender
of the certificate representing such Share.

         SECTION 2.08 Employee Stock Options. On the latest of (i) the
Completion of the Offer (ii) the first business day of January 2000 or (iii)
the earlier of (A) 30 days after termination notice is given in accordance with
the terms of the plan governing the Options (as defined herein) or (B) the date
that the Option holder agrees to the treatment provided in this Section 2.08,
each holder of then outstanding options to purchase Shares granted by the
Company (whether or not then currently exercisable) (the "Options") will be
entitled to receive, and shall receive, at the sole election of the holder of
such Option in settlement of each Option where the amount set forth in clause
(i) below is positive, a cash payment from the Company in an amount equal to
the product of (i) the Transaction Consideration minus the exercise price per
Share of the Option and (ii) the number of Shares covered by such Option. Such
payment shall be reduced by any applicable withholding taxes. If and to the
extent required by the terms of the plan governing such Options or pursuant to
the terms of any Option granted thereunder, each of Parent and the Company
shall use its best efforts to obtain the consent of each holder of outstanding
Options to the foregoing treatment of such Options, including without
limitation, giving the termination notice contemplated by the plan governing
such Options. The Company, acting through its Board of Directors or any
committee thereof, shall have the right at any time or from time to time
following the execution hereof to accelerate and vest, in full or in part, any
and all Options not currently exercisable in full. Effective as of the
Effective Time, the Company, acting through its Board or any committee thereof,
shall terminate those Options with an exercise price that is greater than the
Transaction Consideration.





                                       7
<PAGE>   11

         SECTION 2.09 Conversion of Purchaser Common Stock. Each share of
common stock of Purchaser issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the
part of the holder thereof, be converted into and exchangeable for one share of
common stock of the Surviving Corporation.

         SECTION 2.10 Stockholders' Meeting. If required by applicable law, in
order to consummate the Merger, the Company, acting through its Board, shall,
subject to the Board's fiduciary duties under applicable law, as advised by
counsel:

                  (a) duly call, give notice of, convene and hold a special
         meeting (the "Special Meeting") of its stockholders as soon as
         practicable following the Completion of the Offer (provided that, if a
         Form 15 is promptly filed with the SEC after such completion, the
         Board shall be entitled to delay giving notice until the registration
         of the Company's Common Stock under the Exchange Act has been
         terminated, but not more than one hundred (100) days after the
         Completion of the Offer) for the purpose of considering and taking
         action upon this Agreement;

                  (b) prepare and file with the SEC the Proxy Statement in
         accordance with all applicable requirements of the Exchange Act;

                  (c) subject to its fiduciary duties under applicable law,
         include in the Proxy Statement (as defined in Section 4.07) the
         recommendation of its Board that stockholders of the Company vote in
         favor of the approval and adoption of this Agreement and the Merger;
         and

                  (d) use its reasonable efforts to (i) obtain and furnish the
         information required to be included by it in the Proxy Statement, and
         after consultation with Parent, respond promptly to any comments made
         by the SEC with respect to the Proxy Statement and any preliminary
         version thereof, if filing with the SEC is required, and cause the
         Proxy Statement to be mailed to its stockholders at the earliest
         practicable time following the expiration or termination of the Offer
         and (ii) obtain the necessary approval of this Agreement by its
         stockholders. Parent agrees that, at the Special Meeting, all of the
         Shares then owned by Parent, Purchaser or any other entity controlled
         by Parent will be voted in favor of approval and adoption of this
         Agreement.

         SECTION 2.11 Merger Without Meeting of Stockholders. Notwithstanding
the foregoing, in the event that Purchaser, or any other direct or indirect
subsidiary of Parent or other entity controlled by Parent, shall acquire at
least ninety percent (90%) of the outstanding shares of the capital stock of
the Company, the parties hereto agree, at the request of Parent or Purchaser,
to take all necessary and appropriate action to cause the Merger to become
effective, as soon as practicable after the expiration of the Offer, without a
meeting of stockholders of the Company, in accordance with Section 253 of the
DGCL.

         SECTION 2.12 Closing. Upon the terms and subject to the conditions
hereof, as soon as practicable after consummation of the Offer and after the
vote of the stockholders of the Company in favor of the approval of this
Agreement has been obtained, the Company shall execute in the manner required
by the DGCL and deliver to the Secretary of State of the State of Delaware a
duly executed and verified certificate of merger (or certificate of ownership
and merger) as required by the DGCL and the parties shall take such other and
further actions as may be required by law to make the Merger effective. Prior
to the filings referred to in this Section 2.12, a closing (the "Closing") will
be held at the offices of Wolf, Block, Schorr and Solis-Cohen LLP, 1650 Arch
Street, Philadelphia, Pennsylvania (or such other place as the parties may
agree) for the purpose of confirming all of the foregoing.

                                  ARTICLE III
                     DISSENTING SHARES; EXCHANGE OF SHARES;
                            LOST CERTIFICATES; ETC.

         SECTION 3.01 Dissenting Shares. Notwithstanding anything in this
Agreement to the contrary, Shares which are issued and outstanding immediately
prior to the Effective Time and which are held by stockholders who object to
the Merger and comply with all of the relevant provisions of Section 262 of the
DGCL (the "Dissenting Shares") shall not be converted into or be exchangeable
for the right to receive the consideration provided in Section 2.07 of this
Agreement but shall instead be entitled to receive payment of the appraised
value of such Shares in accordance with the relevant provisions of such Section
262, unless and until such holders shall have failed to perfect or shall have
effectively withdrawn or lost their rights to appraisal and payment under the
DGCL. If any such holder shall have so failed to perfect or shall have
effectively withdrawn or lost such right, such holder's Shares shall thereupon
be deemed to have been converted into and to have become exchangeable for, at
the Effective Time, the right to receive the consideration provided in Section
2.07. The Company shall give Parent (i) prompt notice of any written demand for
appraisal, and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal. The Company shall not, without the prior
consent of Parent, voluntarily make any payment, settle any demands or approve
any withdrawals.

         SECTION 3.02 Exchange of Shares.

                  (a) Prior to the Effective Time, Parent shall designate a
         bank or trust company or similar entity reasonably acceptable to the
         Company which is authorized to exercise corporate trust or stock
         powers to act as Exchange Agent in the Merger (the "Exchange Agent").
         Prior to the Effective Time, Parent will provide the Exchange Agent
         funds necessary to make the cash payments contemplated by Section 2.07
         (the "Payment Fund"). The Exchange Agent shall cause the Payment Fund
         to be (i) held for the benefit of the Shares and (ii) promptly applied
         to making the payments provided for in Section 2.07. The Payment Fund
         shall not be used for any purpose that is not provided for herein. The
         Payment Fund may be transferred from the Escrowed Funds after the
         expiration of the Offer.

                  (b) Promptly after the Effective Time, Parent shall cause the
         Exchange Agent to mail to each record holder, as of the Effective
         Time, of an outstanding certificate or certificates which immediately
         prior to the Effective Time represented outstanding Shares (the
         "Certificates"), one or more forms of 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 proper delivery of the
         Certificates to the Exchange Agent) and instructions for use in
         effecting the surrender of the Certificate or payment therefor. Upon
         surrender to the Exchange Agent of a Certificate, together with such
         letter of transmittal duly executed, and such other documents as may
         reasonably be required by the Exchange Agent, the holder of such
         Certificate shall be entitled to receive in exchange therefor, and
         Parent shall cause the Exchange Agent to promptly so pay, cash in an
         amount equal to the product of the number of Shares represented by
         such Certificate multiplied by the amount of the Transaction
         Consideration with respect to the Shares, and such Certificate shall
         then be canceled. No interest will be paid or accrued on the cash
         payable upon the surrender of any Certificate. If payment is to be
         made to a person other than the person in whose name the Certificate
         surrendered is registered, it shall be a condition of payment that the
         Certificate so surrendered shall be properly endorsed or otherwise in
         proper form for transfer and that the person requesting such payment
         shall pay transfer or other taxes required by reason of the payment to
         a person other than the registered holder of the Certificate
         surrendered or establish to the satisfaction of the Exchange Agent
         that such tax has been paid or is not applicable. Until surrendered in
         accordance with the provisions of this Section 3.02, each Certificate
         (other than Certificates representing Shares held by Parent or any
         subsidiary of Parent or of the Company and Dissenting Shares) shall
         represent for all purposes the right to receive the Transaction
         Consideration in cash multiplied by the number of Shares evidenced by
         such Certificate, without any interest thereon. Any funds remaining
         with the Exchange Agent one year following the Effective Time shall be
         returned to Parent after which time former stockholders of the
         Company, subject to applicable law, shall look only to Parent for
         payment of amounts due hereunder, without interest thereon.

<PAGE>   14

                  (c) After the Effective Time there shall be no transfers on
         the stock transfer books of the Surviving Corporation of the Shares
         which were outstanding immediately prior to the Effective Time. If,
         after the Effective Time, Certificates are presented to the Surviving
         Corporation or the Exchange Agent, they shall be canceled and
         exchanged for cash as provided in Article II and this Article III.

         SECTION 3.03. Lost Certificates. In the event that any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the person claiming such Certificate to be lost, stolen or
destroyed and, if reasonably required by Parent (which shall not exceed amounts
generally required by Parent from holders of Parent's capital stock under
similar circumstances), the granting of an indemnity reasonably satisfactory to
Parent against any claim that may be made against it, the Surviving Corporation
or the Exchange Agent, with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate the
Transaction Consideration with respect to such Certificate, to which such
person is entitled pursuant hereto.

         SECTION 3.04. Withholding Rights. Each of the Surviving Corporation
and Parent shall be entitled to deduct and withhold from the consideration
otherwise payable to any person pursuant to this Article such amounts as it is
required to deduct and withhold with respect to the making of such payment
under any provision of federal, state, local or foreign tax law. If the
Surviving Corporation or Parent, as the case may be, so withholds amounts, such
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Shares in respect of which the Surviving Corporation or
Parent, as the case may be, made such deduction and withholding.

         SECTION 3.04. Investment of Funds. The Payment Fund shall be invested
by the Exchange Agent in obligations of, or guaranteed by, the United States of
America, in commercial paper obligations rated A-1 or P-l or better by Moody's
Investor Services or Standard & Poor's Corporation, respectively, in each case
with maturities not exceeding seven days or investments of comparable risk and
return. All earnings thereon shall inure to the benefit of Parent or the
Surviving Corporation.

         SECTION 3.05. No Liability. None of Parent, Purchaser, the Company or
the Exchange Agent shall be liable to any person in respect of any Transaction
Consideration 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 Transaction Consideration in respect of such
Certificate would otherwise escheat to or become the property of any public
official), 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.

                                   ARTICLE IV
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as set forth in the Disclosure Schedule delivered to Parent by
the Company prior to the execution of this Agreement, the Company represents
and warrants to Parent and Purchaser as follows:

         SECTION 4.01 Organization. Each of the Company and its subsidiaries is
a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation, and each such corporation has
all requisite corporate power and corporate authority to own, operate and lease
its respective properties and to carry on its businesses substantially as they
are being conducted on the date of this Agreement, except for such failures to
be so organized or in good standing which would not individually or in the
aggregate be reasonable likely to have a Material Adverse Effect (as defined in
Section 9.11 hereof). The Company and each of its subsidiaries is duly
qualified and in good standing in each jurisdiction in which the nature of the
property owned, leased or operated by it or the nature of the business
conducted by it requires such qualification except for such failures to be so
qualified or in good standing which are not reasonably likely to have a
Material Adverse Effect. The Company's Certificate of Incorporation, as
amended, and Amended and Restated Bylaws, as amended, are in the same form as
previously provided to Parent and Purchaser.

         SECTION 4.02 Capitalization; Subsidiaries. The authorized capital
stock of the Company consists of 25,000,000 shares of Common Stock, par value
$.04 per share and 5,000,000 shares of preferred stock, par value $.01 per
share (the "Preferred Stock"). As of October 15, 1999, there were 1,044,631
shares of Common Stock and 3,476,900 Series A Preferred Shares issued and
outstanding and 869,225 Shares were held in the Company's treasury. As of
October 15, 1999, except for the obligation of the Company to issue (a) 308,018
Shares pursuant to Options currently outstanding (including the currently
non-exercisable portions thereof), and (b) Shares pursuant to an Employee Stock
Purchase Plan, there are not outstanding any options, warrants, calls,
convertible securities, subscriptions or other rights or other agreements or
commitments obligating the Company or any of its subsidiaries to issue,
transfer or sell any shares of capital stock of the Company or any of its
subsidiaries. No Options have exercise prices below the Transaction
Consideration except as and to the extent set forth on Exhibit C to the
Disclosure Schedule. All issued and outstanding Shares are validly issued,
fully paid and nonassessable and are not subject to, and were not issued in
violation of, preemptive rights. There are no voting trusts or other agreements
or understandings to which the Company is a party with respect to the voting of
the capital stock of the Company or any of its subsidiaries.

         All of the outstanding shares of capital stock of the Company's
subsidiaries are owned, directly or indirectly, by the Company free and clear
of all liens, claims, options, charges, security interests or other legal and
equitable rights and encumbrances of whatsoever nature. All issued and
outstanding shares of capital stock of the Company's subsidiaries are validly
issued, fully paid and nonassessable and are not subject to, and were not
issued in violation of, preemptive rights.

         SECTION 4.03 Authority Relative to this Agreement; Compliance with
Laws and Court Orders. The Company has full corporate power and authority to
execute and deliver this Agreement and, subject to approval and adoption of
this Agreement by the holders of Shares representing a majority of the votes
which may be cast by holders of the Shares to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized by the Board and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or to consummate the
transactions so contemplated (other than the approval of this Agreement by the
holders of Shares representing a majority of the votes which may be cast by
holders of Shares). This Agreement has been duly and validly executed and
delivered by the Company and, assuming this Agreement has been duly authorized,
executed and delivered by each of Parent and Purchaser, this Agreement
constitutes a valid and binding agreement of the Company, enforceable against
the Company in accordance with its terms, except that (i) enforcement may be
subject to applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws, now or hereafter in effect, affecting creditors' 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 proceeding therefor may be brought.
The Company and its subsidiaries are and have been in compliance with, and to
the knowledge of the Company are not under investigation with respect to and
have not been threatened to be charged with or given notice of any violation
of, any applicable law, statute, ordinance, rule, regulation, judgment,
injunction, order or decree, including, without limitation, any Environmental
Laws, except for (i) failures to comply or violations that have not had and
would not reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect.

         SECTION 4.04 Absence of Certain Changes. Since June 30, 1999 and prior
to the Board Transition Date, neither the Company nor any of its subsidiaries
has suffered any change or changes in the financial condition or business,
results of operations or assets which has resulted or reasonably would be
expected to result in a Material Adverse Effect. Since June 30, 1999, there has
not been (a) any declaration, setting aside or payment of any dividend or other
distribution in respect of the shares of capital stock of the Company, or any
redemption or other acquisition by the Company or any of its subsidiaries of
any shares of capital stock of the Company except for (i) the exchange by
Securicor Communications Limited, a company organized under the laws of England
and Wales, of 3,476,900 shares of Common Stock (prior to adjustment for the
reverse stock split referenced immediately below) for 3,476,900 shares of
Series A Preferred Stock of the Company on September 30, 1999; and (ii) the
one-for-four reverse stock split effected on October 15, 1999; (b) (i) any
increase in the compensation paid, payable or to become payable by the Company
or any of its subsidiaries (including the rate and terms thereof) to its
directors, officers, employees or consultants, except increases which occur in
the ordinary course of business in accordance with its customary practices or
(ii) any increase in the rate or terms of any bonus, insurance, pension or
other employee benefit plan, payment or arrangement made to, for or with any
such directors, officers or employees, except increases occurring in the
ordinary course of business in accordance with its customary practices; (c) any
entry into any agreement, commitment or transaction by the





                                      13
<PAGE>   17

Company or any of its subsidiaries, which is material to the Company and its
subsidiaries taken as a whole (except agreements, commitments or transactions
in the ordinary course of business in accordance with its customary practices);
(d) any material change by the Company or any of its subsidiaries in accounting
methods, principles or practices except as required by generally accepted
accounting principles; (e) except as contemplated by this Agreement, any
amendment of any material term of any outstanding security of the Company or
any of its subsidiaries; (f) any incurrence, assumption or guarantee by the
Company or any of its subsidiaries of any indebtedness for borrowed money (i)
exceeding $4,000,000 in the aggregate or (ii) having a term longer than one
year in duration; (g) any creation or other incurrence by the Company or any of
its subsidiaries of any lien on any asset other than in the ordinary course of
business consistent with past practices; (h) any damage, destruction or other
similar casualty loss (whether or not covered by insurance) affecting the
business or assets of the Company or any of its subsidiaries that has resulted,
or could reasonably be expected to result, in an aggregate amount in excess of
$1,000,000; (i) any transaction or commitment made, or any contract or
agreement entered into, by the Company or any of its subsidiaries relating to
its assets or business (including the acquisition or disposition of any assets)
or any relinquishment by the Company or any of its subsidiaries of any contract
or other right, in either case, material to the Company and its subsidiaries,
taken as a whole, other than transactions and commitments in the ordinary
course of business consistent with past practices and those contemplated by
this Agreement; (j) any tax election, other than those consistent with past
practice, not required by law or any settlement or compromise of any tax
liability in either case that is material to the Company and its subsidiaries;
(k) any grant of any severance or termination pay to (or amendment to any
existing arrangement with) any director or officer of the Company or any of its
subsidiaries; (l) to the Company's knowledge, any labor dispute, other than
routine individual grievances, or any activity or proceeding by a labor union
or representative thereof to organize any employees of the Company or any of
its subsidiaries, which employees were not subject to a collective bargaining
agreement at June 30, 1999, or any lockouts, strikes, slowdowns, work stoppages
or threats thereof by or with respect to such employees.

         SECTION 4.05 No Undisclosed Liabilities. Neither the Company nor any
of its subsidiaries has incurred any liabilities of any nature, whether or not
accrued, contingent or otherwise, which would be required to be included on a
balance sheet prepared in accordance with generally accepted accounting
principles, except for liabilities that are reflected on the Company's June 30,
1999 balance sheet or that would not have or could not reasonably be expected
to have a Material Adverse Effect.

         SECTION 4.06 Reports. The Company has timely filed all required forms,
reports and documents (including all prospectuses and all registration
statements) with the SEC required to be filed by it with respect to all periods
commencing on or after October 1, 1997 pursuant to the
federal securities laws and the SEC rules and regulations thereunder, all of
which have complied in all material respects with all applicable requirements




                                      14
<PAGE>   18

of the Securities Act of 1933 (the "Securities Act") and the Exchange Act, and
the rules and regulations promulgated thereunder (the "Company Filings"). None
of such forms, reports or documents (excluding the financial statements
included therein, which are dealt with in the following paragraph), at the time
filed, contained any untrue statement of a material fact or omitted 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.

         The consolidated balance sheets and the related consolidated
statements of income, retained earnings and changes in financial position
(including the related notes thereto) of the Company included in the Company's
Annual Report on Form 10-K for the fiscal year ended September 30, 1998, and in
the Company's Quarterly Report on Form 10-Q for the quarter ended June 30,
1999, present fairly in all material respects the consolidated financial
position of the Company as of their respective dates, and the results of
consolidated operations and consolidated cash flows for the periods presented
therein, all in conformity with generally accepted accounting principles
applied on a consistent basis, except (i) as otherwise noted therein, (ii) in
the case of quarterly financial statements for year-end audit adjustments and
(iii) in the case of the quarterly financial statements to the extent they may
not include footnotes or may be condensed or summary financial statements.

         The unaudited pro forma estimated consolidated balance sheet and
related consolidated unaudited pro forma estimated statements of income,
retained earnings and changes in financial position of the Company for the year
ended September 30, 1999 attached as Exhibit A to the Disclosure Schedule, to
the knowledge of the Company, present fairly in all material respects the
consolidated position of the Company, and the results of consolidated
operations and consolidated cash flows for the periods presented therein, all
in conformity with generally accepted accounting principles applied on a
consistent basis, except to the extent that they do not include footnotes and
may be condensed or summary financial statements and except that such
statements do not reflect the Series A Preferred Stock or any adjustments
relative to expected lease arrangements reflected in the Disclosure Schedule.

         SECTION 4.07 Offer Documents; Proxy Statements; Other Information.
None of the information relating to the Company and its subsidiaries supplied
in writing by the Company specifically for inclusion in the Offer Documents,
including any amendments or supplements thereto will at the respective times
the Offer Documents or any amendments or supplements thereto are filed with the
SEC, to the knowledge of the Company, 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 were made, not misleading. The Schedule 14D-9,
will comply in all material respects with the Exchange Act. If a Proxy
Statement is required for the consummation of the Merger under applicable law,
the Proxy Statement will comply in all material respects with the Exchange Act,
if applicable, except that no representation is made by the Company with
respect to information supplied in writing by Parent or Purchaser specifically
for inclusion in the Proxy Statement. The letter to stockholders, notice of
meeting, proxy statement and form of proxy, or the information statement, as
the case may be, to be distributed to stockholders in connection with the
Merger, or any schedules required to be filed with the SEC in connection
therewith are collectively referred to herein as the "Proxy Statement".

<PAGE>   19

         SECTION 4.08 Consents and Approvals; No Violation. Neither the
execution and delivery of this Agreement by the Company nor the consummation of
the transactions contemplated hereby will (i) conflict with or result in any
breach of any provision of the Amended and Restated Certificate of
Incorporation, as amended, or Amended and Restated ByLaws (or other similar
governing documents) of the Company, (ii) require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority or body, except (A) in connection with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), if applicable, (B) pursuant to the Exchange Act or the rules and
requirements of NASD, (C) the filing of a certificate of merger (or certificate
of merger and ownership) pursuant to the DGCL or (D) where the failure to
obtain such consent, approval, authorization or permit, or to make such filing
or notification, would not individually or in the aggregate when taken together
with all such other failures have a Material Adverse Effect; (iii) result in a
default (or give rise to any right of termination, unilateral modification or
amendment, cancellation or acceleration) under any of the terms, conditions or
provisions of any note, license, agreement or other instrument or obligation to
which the Company or any of its subsidiaries is a party or by which the
Company, any of its subsidiaries or any of their respective assets may be
bound, except for such defaults (or rights of termination, unilateral
modification or amendment, cancellation or acceleration) as to which requisite
waivers or consents have been obtained prior to the date Shares are first
accepted for payment under the Offer or which in the aggregate would not have a
Material Adverse Effect; or (iv) violate any order, writ, injunction, decree,
judgment, ordinance, statute, rule or regulation applicable to the Company, any
of its subsidiaries or any of their respective properties or businesses, except
for violations (other than of orders, writs, injunctions or decrees issued
against the Company or any of its subsidiaries or naming the Company or any of
its subsidiaries as a party) which would not in the aggregate have a Material
Adverse Effect.

         SECTION 4.09 Litigation, etc. As of the date of this Agreement, there
is no claim, action or proceeding pending or, to the knowledge of the Company,
threatened against the Company or any of its subsidiaries or their respective
properties or businesses before any court or governmental or regulatory
authority or body acting in an adjudicative capacity with respect to which
there is a reasonable likelihood of an adverse determination which would have a
Material Adverse Effect. Neither the Company nor any of its subsidiaries nor
any of their respective properties or businesses is subject to any outstanding
order, writ, judgment, stipulation, award, injunction or decree of any court
issued against the Company or any of its subsidiaries or naming the Company or
any of its subsidiaries as a party which has a Material Adverse Effect.

         SECTION 4.10 Title to Properties; Encumbrances. The Company and each
of its subsidiaries has good title to all properties, interests in properties
and assets (real and personal) reflected in the consolidated balance sheet of
the Company as at June 30, 1999 free and clear of all mortgages, liens,
pledges, charges or encumbrances of any kind or character, except liens for
current taxes not yet due and payable and except for such mortgages, liens,
pledges, charges or encumbrances which would not in the aggregate have a
Material Adverse Effect.

         SECTION 4.11 Benefit Plans.

                  (a) The Company does not have any Company Benefit Plan (as
         defined herein) except for the 1997 Stock Incentive Plan, the Employee
         Stock Purchase Plan or as set forth on the Disclosure Schedule. With
         respect to each employee benefit plan (as defined in Section 3(3) of
         the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA")), and any material bonus, pension, profit sharing, deferred
         compensation, incentive compensation, stock ownership, stock purchase,
         stock option, phantom stock, retirement, vacation, severance,
         disability, death benefit, hospitalization or insurance (all of the
         foregoing being herein called the "Company Benefit Plans"), maintained
         or contributed to by the Company or any of its subsidiaries, the
         Company has made available, to the extent applicable, to Parent a true
         and correct copy of (i) the most recent annual report (Form 5500)
         filed with the Internal Revenue Service, (ii) such Company Benefit
         Plan, (iii) each trust agreement and group annuity contract, if any,
         relating to such Company Benefit Plan and (iv) the most recent
         actuarial report or valuation relating to a Company Benefit Plan
         subject to Title IV of ERISA.

                  (b) With respect to the Company Benefit Plans, individually
         and in the aggregate, no event has occurred, and to the knowledge of
         the Company, there exists no condition or set of circumstances in
         connection with which the Company or any of its subsidiaries would be
         subject to any liability that is reasonably likely to have a Material
         Adverse Effect (except liability for benefit claims and funding
         obligations payable in the ordinary course), under ERISA, the Code or
         any other applicable law.

                  (c) Each of the Company Benefit Plans has been operated and
         administered in all material respects in accordance with its terms and
         applicable laws, including, but not limited to, ERISA and the Code.

                  (d) Except as disclosed in the Company's Filings or as
         provided for in this Agreement, as of the date of this Agreement,
         neither the Company nor any of its subsidiaries is a party to any oral
         or written (i) consulting agreement not terminable on 60 days' or less
         notice involving the payment of more than $1,000,000 per annum, (ii)
         union or collective bargaining agreement, (iii) agreement with any
         executive officer or other key employee of the Company or any of its
         subsidiaries the benefits of which are contingent, or the terms of
         which are materially altered, upon the occurrence of a transaction
         involving the Company of the nature contemplated by this Agreement or
         agreement with respect to any executive officer of the Company
         providing any term of employment or compensation guarantee extending
         for a period longer than three years and for the payment of in excess
         of $1,000,000 per annum, or (iv) agreement or plan, including any
         stock option plan, stock appreciation right plan, restricted stock
         plan or stock purchase plan, any of the benefits of which will be
         increased, or the vesting of the benefits of which will be
         accelerated, by the occurrence of any of the transactions contemplated
         by this Agreement or the value of any of the benefits of which will be
         calculated on the basis of any of the transactions contemplated by
         this Agreement.

                  (e) Except as disclosed in the Disclosure Schedule, neither
         the Company nor any of its subsidiaries currently contributes to or
         maintains any plan subject to Title IV of ERISA, other than a
         "multiemployer plan" as defined in Section 3 (37) of ERISA (a
         "Multiemployer Plan"). With respect to any Multiemployer Plan or other
         plan subject to Title IV of ERISA which the Company or any of its
         subsidiaries has contributed to or maintained during the past five
         years, neither the Company nor any of its subsidiaries has any
         contingent liability that (i) is reasonably likely to become a
         liability of Parent or its subsidiaries after the Effective Time and
         (ii) individually or in the aggregate, would have a Material Adverse
         Effect.

                  (f) Except as set forth in the Disclosure Schedule or as
         otherwise contemplated by this Agreement, the consummation of the
         transactions contemplated by this Agreement will not entitle any
         employee or independent contractor of the Company or any of its
         subsidiaries to severance pay or 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
         Company Benefit Plan.

                  (g) Except as otherwise contemplated by this Agreement, there
         has been no amendment to, written interpretation or announcement
         (whether or not written) by the Company or any of its subsidiaries
         relating to, or change in employee participation or coverage under,
         any Company Benefit Plan which would increase materially the expense
         of maintaining such Company Benefit Plan above the level of the
         expense incurred in respect thereof for the fiscal year ended
         September 30, 1999.

         SECTION 4.12 Compliance With Agreements; Law. Neither the Company nor
any of its subsidiaries is in default or violation of (i) any term, provision
or condition of (A) its Amended and Restated Certificate of Incorporation, as
amended, or Amended and Restated ByLaws (or similar charter documents) or (B)
any note, license, agreement or other instrument or obligation to which the
Company or any of its subsidiaries is a party or by which the Company, any of
its subsidiaries or any of their respective assets may be bound ("agreement"),
or (ii) any judgment, order, writ, injunction, decree, stipulation, award, law,
ordinance, rule or regulation of any governmental or regulatory authority or
body (including, but not limited to, any law, ordinance, rule or regulation
relating to the protection of the environment), except for possible violations
in the case of clauses (i)(B) and (ii) which in the aggregate do not and,
insofar as reasonably can be foreseen, in the future will not have a Material
Adverse Effect. To the knowledge of the Company, no other party to any such
agreement is, or, based on existing facts and circumstances, with the passage
of time will be, in default or violation of any such agreement except for
possible violations of such agreements which will not have a Material Adverse
Effect. All licenses, permits and other governmental authorizations held by the
Company or any of its subsidiaries are valid and sufficient for all businesses
conducted by the Company and its subsidiaries except where the failure to hold
such licenses, permits and other governmental authorizations would not in the
aggregate have a Material Adverse Effect.

been asserted or, to the knowledge of the Company, threatened by any person (i)
to the effect that the sale or use of any product or process as now used or
offered by the Company or any subsidiary infringes on any patents, (ii) against
the use by the Company or any of its subsidiaries of any trademarks, trade
names, technology, know-how or processes necessary for the operation of the
business of the Company and its subsidiaries as currently conducted or
presently contemplated or (iii) challenging or questioning the validity or
effectiveness of any of the Company Intellectual Property.

         SECTION 4.14  Taxes.

                  (a) The Company and each of its subsidiaries on or prior to
         the date of this Agreement has filed or has had filed on its behalf,

         Tax Returns (as defined herein) required to be filed prior to the
         Effective Time with respect to Taxes (as defined herein) of the
         Company and each of its subsidiaries, and such Tax Returns are true,
         correct and complete in all material respects.

                  (b) All material Taxes with respect to the Company and its
         subsidiaries have been paid in full to the extent required to be so
         paid as of the date of this Agreement or have been provided for in
         accordance with generally accepted accounting principles on the
         Company's most recent balance sheet (as of the date of such balance
         sheet) which is part of the Company Filings.

                  (c) There are no outstanding agreements or waivers extending
         the statutory period of limitations applicable to any federal, state,
         local or foreign income or other material Tax Returns required to be
         filed by or with respect to the Company and its subsidiaries.

                  (d) No deficiency, delinquency or default for any Tax has
         been claimed, proposed or assessed against the Company or any of its
         subsidiaries which has not been abated or paid in full or which is
         being contested in good faith by the Company, and to the Company's
         knowledge, neither the Company nor any subsidiary of the Company has
         received written notice of any such deficiency, delinquency or default
         nor does the Company otherwise have knowledge of any threat of any
         governmental entity to assert




                                      19
<PAGE>   23

         such deficiency, delinquency or default or any facts or circumstances
         that would form a basis of such threat.

                  (e) There are no liens for Taxes upon the assets of the
         Company or any of its subsidiaries except statutory liens for current
         Taxes not yet due.

                  (f) Neither the Company nor any of its subsidiaries is
         currently the subject of any audit with respect to any Tax Return nor
         has the Company or any subsidiary been notified that the Company or

                  (g) Neither the Company nor any of its subsidiaries is a
         party to or bound by or has any obligation under any written or
         unwritten tax sharing or similar agreement or arrangement.

                  (h) For purposes of this Agreement, (i) "Taxes" shall mean
         all taxes, government fee, charges, fees, levies or other assessments
         of any kind, including, without limitation, income, gross receipts,
         sales, use, ad valorem, goods and services, capital, transfer,
         franchise, profits, license, withholding, payroll, employment,
         employer health, excise, estimated, severance, stamp, occupation,
         property or other taxes, customs duties, fees, assessments or charges

         additions to tax or additional amounts imposed by any taxing authority
         and (ii) "Tax Return" shall mean any report, return, document,
         declaration or other information or filing required to be supplied to
         any taxing authority or jurisdiction with respect to Taxes.

         SECTION 4.15 Antitakeover Statutes. The Board has taken the necessary
action to render Section 203 of the Delaware General Corporation Law, and any
other potentially applicable antitakeover or similar statute or regulation
inapplicable to this Agreement, the Merger and the Offer and the transactions
contemplated hereby.


                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES
                            OF PARENT AND PURCHASER

         Parent and Purchaser represent and warrant to the Company as follows:

         SECTION 5.01 Organization and Good Standing. Each of Parent and

corporate proceedings on the part of Parent or Purchaser are necessary to
authorize this Agreement, or commence the Offer or to consummate the
transactions contemplated by this Agreement (including the Offer). This
Agreement has been duly and validly executed and delivered by each of Parent
and Purchaser and, assuming this Agreement has been duly authorized, executed
and delivered by the Company, this Agreement constitutes a valid and binding
agreement of each of Parent and Purchaser, enforceable against each of Parent
and Purchaser in accordance with its terms, except that (i) enforcement may be
subject to applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws, now or hereafter in effect, affecting creditors' 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 proceeding therefor may be brought.

         SECTION 5.03 Consents and Approvals; No Violation. Neither the
execution and delivery of this Agreement by Parent and Purchaser nor the

result in any breach of any provision or the respective Certificate of
Incorporation or By-Laws (or other similar governing documents) of Parent or
any of its subsidiaries, (ii) require any consent, approval, authorization or
permit of, or filing with or notification to, any governmental or regulatory

termination, unilateral modification or amendment, cancellation or
acceleration) under any of the terms, conditions or provisions of any note,
license, agreement or other instrument or obligation to which the Parent or any
of its subsidiaries is a party; or (iv) violate any order, writ, injunction,
decree, judgment, ordinance, statute, rule or regulation applicable to Parent,
any of its subsidiaries or any of their respective properties or businesses.

         SECTION 5.04 Offer Documents; Proxy Statement. The Schedule 14D-1,

amendments or supplements thereto, are filed with the SEC 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 were made, not misleading, except that no
representation is made by Parent with respect to information supplied by the
Company specifically for inclusion in the Offer Documents. None of the
information supplied by Parent and its affiliates specifically for inclusion in
the Proxy Statement will, at the time the Proxy Statement is mailed, or, at the
time of the Special Meeting or at the Effective Time, 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 were made, not misleading.

         SECTION 5.05 Ownership of Shares. As of the date hereof, neither
Parent nor Purchaser nor any subsidiary or affiliate of Parent has beneficial
ownership (within the meaning of Rule 13d-3 under the Exchange Act) of any
Shares.

                                   ARTICLE VI
                                   COVENANTS

         SECTION 6.01 Conduct of Business of the Company.

                  (a) Except as contemplated by this Agreement, during the
         period from the date of this Agreement to such time at which directors
         of the Company affiliated with or designated by Parent or Purchaser
         shall constitute a majority of the Board (such time, the "Board
         Transition Date"), the Company and its subsidiaries will each conduct
         its operations according to its ordinary and usual course of business,
         substantially consistent with past practice. Without limiting the
         generality of the foregoing, and except as otherwise contemplated by
         this Agreement, neither the Company nor any of its subsidiaries will,
         prior to the Board Transition Date, without the prior written consent
         of Parent (i) issue, sell or pledge, or authorize or propose the
         issuance, sale or pledge of (A) additional shares of capital stock of
         any class of the Company, or securities convertible into any such
         shares, or any rights, warrants or options to acquire any such shares
         or other convertible securities, other than such issuance of Shares
         pursuant to the exercise of Options outstanding on the date hereof,
         and other than the issuance of Shares in connection with the Company's
         employee stock purchase plan, or (B) any other securities in respect
         of, in lieu of or in substitution for, Shares outstanding on the date
         hereof, (ii) purchase or otherwise acquire, or propose to purchase or
         otherwise acquire, any outstanding Shares, (iii) declare or pay any
         dividend or distribution on any shares of its capital stock, (iv)
         propose or adopt any amendments to its Amended and Restated
         Certificate of Incorporation, as amended, or Amended and Restated
         By-Laws, (v) agree in writing or otherwise to take any of the
         foregoing actions or any action which would prevent the conditions to
         Purchaser's obligation to purchase Shares under the Offer or Parent's
         and Purchaser's obligation to consummate the Merger from being
         satisfied; provided, however, that the Company shall be permitted to
         accelerate the vesting schedule of all outstanding Options. The
         Company shall, through its Board or any committee thereof, terminate
         the Company's Employee Stock Purchase Plan so that no Shares shall be
         issued thereunder subsequent to the date of this Agreement.

                  (b) Except as set forth on the Disclosure Schedule or
         contemplated by this Agreement, from the date of this Agreement to the
         Board Transition Date, (i) the Company will not, and will not permit
         any of its subsidiaries to, merge or consolidate with any other person
         or acquire a material amount of stock or assets of any other person;
         (ii) the Company will not, and will not permit any of its subsidiaries
         to, sell, lease, license or otherwise dispose of any material
         subsidiary or material amount of assets, securities or property except
         (A) pursuant to existing contracts or commitments and (B) in the
         ordinary course consistent of business with past practice; (iii) the





                                      22
<PAGE>   26

         Company will (and will cause its subsidiaries to) use reasonable
         efforts not to, (A) take any action that (x) would make any
         representation and warranty of the Company hereunder that is qualified
         by materiality or Material Adverse Effect inaccurate in any respect
         at, or as of any time prior to, the Effective Time or (y) would make
         any representation or warranty of the Company hereunder that is not so
         qualified to be inaccurate in any material respect at, or as of any
         time prior to, the Effective Time or (B) omit to take any action
         necessary to prevent any such representation or warranty from being
         inaccurate in any respect or material respect, as the case may be, at
         any such time; (iv) the Company will not, and will not permit any of
         its subsidiaries to, sell, transfer, license, sublicense or otherwise
         dispose of any material intellectual property rights (other than in
         the ordinary course of business consistent with past practice) or
         amend or modify any existing agreements with respect to any material
         intellectual property rights or third party intellectual property
         rights; (v) the Company will not, and will not permit any of its
         subsidiaries to, (A) incur any indebtedness for borrowed money or
         issue any debt securities or assume, guarantee or endorse or otherwise
         as an accommodation become responsible for, the obligations of any
         other person (other than (x) for an amount not exceeding $4,000,000 in
         the aggregate, or make any loans, advances, or capital contributions
         to, or investments in, any other person, (B) enter into or amend any
         contract or agreement other than in the ordinary course of business
         consistent with past practice, (C) authorize or make any capital
         expenditures or purchases of fixed assets that are not currently
         budgeted and that in the aggregate exceeds $1,000,000, (D) terminate
         any material contract to which the Company is a party or amend in any
         material respect any such material contract or (E) enter into or amend
         any contract, agreement, commitment or arrangement to effect any of
         the matters prohibited hereunder; (vi) the Company will not, and will
         not permit any of its subsidiaries to, take any action, other than as
         required by generally accepted accounting principles, to change
         accounting policies or procedures or cash maintenance policies or
         procedures (including, without limitation, procedures with respect to
         revenue recognition, capitalization of development costs, payments of
         accounts payable and collection of accounts receivable); (vii) the
         Company will not, and will not permit any of its subsidiaries to, make
         any tax election not required by law and inconsistent with past
         practice or settle or compromise any tax liability, except to the
         extent the amount of any such settlement or compromise has been
         reserved for on the consolidated financial statements contained in the
         Company's filings with the SEC, (viii) the Company will not, and will
         not permit any of its subsidiaries to, pay, discharge, settle, or
         satisfy any lawsuits, claims, liabilities or obligations (absolute,
         accrued, asserted or unasserted, contingent or otherwise), other than
         the payment, discharge or satisfaction in the ordinary course of
         business consistent with past practice of liabilities reflected or
         reserved against on the Company's September 30, 1999 pro forma balance
         sheet which is attached to the Disclosure Schedule or incurred in the
         ordinary course of business consistent with past practice or other
         payments, discharges or satisfactions which in the aggregate do not
         exceed $1,000,000 or waive the benefits of, or agree to modify in any
         manner, any confidentiality or standstill agreement.

         SECTION 6.02 No Solicitation, etc. From the date of this Agreement
until the earlier of the Board Transition Date or the termination of this
Agreement, the Company will not (and it will use its best efforts to not permit
any of its officers, directors, agents, affiliates, investment bankers,
accountants or attorneys to) directly or indirectly (i) solicit, engage in
discussions or negotiate with any person (whether such discussions or
negotiations are initiated by the Company or otherwise) or take any other
action intended or designed to facilitate the efforts of any person (other than
Parent) relating to the possible acquisition of the Company (whether by way of
merger, purchase of capital stock, purchase of assets or otherwise) or any
material portion of its capital stock or assets (with any such efforts by any
such person, including a firm proposal to make such an acquisition, to be
referred to as an "Alternative Acquisition"), (ii) provide information with
respect to the Company to any person, other than Parent, relating to a possible
Alternative Acquisition by any person, other than Parent, (iii) enter into an
agreement with any person, other than Parent, providing for a possible
Alternative Acquisition, or (iv) make or authorize any statement,
recommendation or solicitation in support of any possible Alternative
Acquisition by any person, other than by Parent. The Company shall and shall
cause its representatives to cease immediately and cause to be terminated all
activities, discussions and negotiations, if any, conducted prior to the date
hereof with respect to any Alternative Acquisition. Notwithstanding anything to
the contrary contained in Section 6.02 or elsewhere in this Agreement, prior to
the consummation of the Offer, the Company may participate in discussions or
negotiations with, and furnish non-public information, and afford access to the
properties, books, records, officers, employees and representatives of the
Company to any person, entity or group if such person, entity or group has
delivered unsolicited to the Company, prior to the consummation of the Offer,
and in writing, a proposal for an Alternative Acquisition which is not subject
to any financing contingency, which the Board by a majority vote in its good
faith judgment (after consultation with its independent financial advisor)
determines that such proposal is reasonably likely to be consummated and if
consummated would be more favorable, from a financial point of view, to the
Company's stockholders than the transactions contemplated by this Agreement and
the Company's Board determines in good faith that it is necessary to furnish
such information and negotiate in order to comply with its fiduciary
obligations to its stockholders (a "Superior Proposal"). In the event the
Company receives a Superior Proposal, nothing contained in this Agreement (but
subject to the terms of this paragraph (b)) will prevent the Board from
executing or entering into an agreement relating to such Superior Proposal and
recommending such Superior Proposal to its stockholders; in such case, the
Board may withdraw, modify or refrain from making its recommendation of the
Offer and the Merger; provided, however that the Company (i) shall have
promptly notified Parent, and in any event within 24 hours, of any proposal for
an Alternative Acquisition received by, any such information requested from, or
any such negotiations or discussions sought to be initiated or recommenced
with, the Company or any of its subsidiaries, indicating, in connection with
such notice, the name of the person making the proposal for an Alternative
Acquisition or taking such action and, in reasonable detail, the significant
terms of any such proposal for an Alternative Acquisition and including with
such notice any documentation relating to such Alternative Acquisition, (ii)
shall provide Parent at least two business days prior written notice of the
Company's intention to execute or enter into an agreement relating to such
Superior Proposal and (iii) may only terminate this Agreement by written notice
to Parent provided no sooner than two business days after Parent's receipt of a
copy of such Superior Proposal (or a detailed description of the significant
terms and conditions thereof).

<PAGE>   28

         SECTION 6.03 Access to Information.

                  (a) Subject to any confidentiality requirements of any
         agreement to which the Company or any of its subsidiaries is a party,
         any regulatory obligations to maintain the confidentiality of
         information or any confidentiality privileges applicable to
         communications between the Company or any of its subsidiaries and its
         respective attorneys or accountants, between the date of this
         Agreement and the Effective Time, upon reasonable prior notice to the
         Company, the Company will give Parent and its authorized
         representatives reasonable access during normal business hours to the
         plants, offices, warehouses and other facilities and to the books and
         records of it and its subsidiaries, will permit Parent to make such
         reasonable inspections during normal business hours as it may
         reasonably request and will cause its officers and those of its
         subsidiaries to furnish Parent with such financial and operating data
         and other information with respect to the business and properties of
         the Company and its subsidiaries as Parent may from time to time
         reasonably request; provided, however, that all such access and
         inspections shall be coordinated by Parent with a designee of the
         Company and shall be conducted in such manner so as not to unduly
         interfere with the normal business operations of the Company or any of
         its subsidiaries.

                  (b) All information received by Parent and its
         representatives pursuant to this Section 6.03 will be subject to the
         confidentiality agreement between Parent or an affiliate thereof and
         the Company.

         SECTION 6.04 Best Efforts. Subject to the terms and conditions herein
provided, each of the parties hereto agrees to promptly effect all necessary
filings under the HSR Act, if any, and use its best efforts to secure all
government clearances (including by taking all reasonable steps to avoid or set
aside any preliminary or permanent injunction or other order of any federal or
state court of competent jurisdiction or other governmental authority). Each of
the parties hereto further agrees to use its reasonable efforts to take, or
cause to be taken, all action, and to do, or cause to be done, all other things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.
In particular, Parent and the Company will use their respective reasonable
efforts to obtain all other consents, authorizations, orders and approvals
required in connection with, and waivers of any violations, breaches and
defaults that may be caused by, the consummation of the Merger or the other
transactions contemplated by this Agreement, other than consents,
authorizations, orders, approvals and waivers the failure to obtain which would
not (A) be material to the consummation of the Merger or the other transactions
contemplated by this Agreement or (B) have a Material Adverse Effect. In case
at any time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement, the proper officers and
directors of each party to this Agreement shall take all such necessary action,
including, without limitation, providing for the sale or other disposition or
the holding separate (through the establishment of a trust or otherwise) of
particular assets or categories of assets, or businesses, of the Company or any
of its subsidiaries.





                                      25
<PAGE>   29

         SECTION 6.05 Public Announcements. Parent and the Company will consult
with each other before issuing any press release or otherwise making any public
statements with respect to the Offer or the Merger and shall not issue any such
press release or make any such public statement prior to such consultation,
except as may be required by law or by obligations pursuant to any listing
agreement with any national securities exchanges or The Nasdaq Stock Market.

         SECTION 6.06 Indemnification; Insurance.

                  (a) Notwithstanding anything to the contrary in Section 2.04,
         Parent and Purchaser agree that all rights to indemnification existing
         in favor, and all limitations on the personal liability of, each
         present and former director, officer, employee or agent of the Company
         or any of its subsidiaries or a director, officer, employee, agent or
         trustee of any employee benefit plan for employees of the Company or
         any of its subsidiaries, and each person who is or was then serving in
         any such capacity (or any person who is or was then serving any other
         corporation or entity in any such capacity at the request of the
         Company) (individually, an "Indemnified Party" and collectively, the
         "Indemnified Parties") provided for in the Company's Amended and
         Restated Certificate of Incorporation, as amended, or Amended and
         Restated By-Laws or similar organizational documents of any Company
         subsidiary as in effect on the date of this Agreement with respect to
         matters occurring prior to the Effective Time shall survive the Merger
         and shall continue in full force and effect for a period of not less
         than six (6) years from the Effective Time; provided, however, that
         all rights to indemnification in respect of any claim for
         indemnification for losses, damages or liabilities of any kind or
         nature incurred (an "Indemnifiable Claim") which is asserted or made
         within such period shall continue until the final disposition of such
         claim. Parent hereby agrees that it shall indemnify any Indemnified
         Party in respect of any Indemnifiable Claim to the extent that the

         effect on the Board Transition Date, or other plans that, in the

         employees for a period of six months.

         SECTION 6.08 Substitution of Letter of Credit. Parent agrees that
prior to the Completion of the Offer it shall either (a) provide a letter of

in effect until the earlier of (i) the Closing of the Merger or (ii) December
31, 2000, or (b) provide substitute financing in amounts and on terms at least

         the occurrence or nonoccurrence of any event the occurrence or
         nonoccurrence of which would be likely to cause any representation or
         warranty contained in this Agreement to be untrue or inaccurate in any
         material respect at or prior to the Effective Time, (ii) any material
         failure of the Company, Parent or Purchaser, as the case may be, to

         and

                  (e) Purchaser shall have purchased the Shares pursuant to the
         Offer; provided, however, that this condition shall be deemed
         satisfied with respect to Parent and Purchaser if Purchaser's failure

         Parent's or Purchaser's obligations hereunder.

                                  ARTICLE VIII
                        TERMINATION; AMENDMENTS; WAIVER

                  (b) by Parent or Purchaser if an occurrence or circumstance
         (except where Parent's or Purchaser's failure to fulfill any of their
         respective obligations under this Agreement is the cause of or
         resulted in such occurrence or circumstance or except where there has
         been a material breach of any representation or warranty on the part

         permanently restraining, enjoining or otherwise prohibiting the Merger
         and such order, decree, ruling or other action shall have become final
         and nonappealable; provided, however, that a termination of this
         Agreement by the Company pursuant to this Section 8.01(c) after the
         Board Transition Date shall require the affirmative vote of a majority
         of the Board and a majority of the Independent Directors;

         pursuant to the Offer, if (i) Purchaser shall discover that any
         representation or warranty made by the Company in this Agreement is
         untrue at the time such representation or warranty was made or (except
         for those representations and warranties made as of a particular date
         which need only be true and correct as of such date) shall not be true
         and correct as of the date of consummation of the Offer, except where
         the failure to be so true and correct would not have a Material
         Adverse Effect, provided that if any such failure to be so true and
         correct is capable of being cured prior to the Final Date, then Parent
         and Purchaser may not terminate this Agreement under this paragraph
         (d) until the Final Date, (ii) there shall have been a breach of any
         covenant or agreement on the part of the Company under this Agreement

         being cured prior to the Final Date, (iii) the Board (x) fails to
         recommend approval and adoption of this Agreement and the Merger by
         the stockholders of the Company or withdraws or amends or modifies in
         a manner adverse to Parent and Purchaser its recommendation or
         approval in respect of this Agreement, the Offer or the Merger, (y)
         makes any recommendation with respect to an Alternative Acquisition
         other than a recommendation to reject such Alternative Acquisition or

         shall have made a written proposal to the Company and not withdrawn
         such proposal for an Alternative Acquisition;

                  (e) by the Company, if (i) the Company shall discover that
         any representation or warranty made by Parent or Purchaser in this
         Agreement is untrue at the time such representation or warranty was
         made or (except for those representations and warranties made as of a
         particular date which need only be true and correct as of such date)
         shall not be true and correct as of the date of consummation of the
         Offer, except where the failure to be so true and correct would not
         materially adversely affect (or materially delay) the consummation of
         the Offer or the Merger, provided that if any such failure to be so
         true and correct is capable of being cured prior to the Final Date,

         been cured or (ii) there shall have been a material breach of any
         covenant or agreement in this Agreement on the part of Parent or
         Purchaser which materially adversely affects (or materially delays)
         the consummation of the Offer or the Merger which shall not be capable
         of being cured prior to the Final Date, or (iii) prior to the
         acceptance of any Shares pursuant to the Offer and the Company is in
         compliance with Section 6.02, such termination is necessary to allow
         the Company to enter into a binding written agreement with respect to
         a proposal for an Alternative Acquisition; provided, however, that a
         termination of this Agreement by the Company pursuant to Section
         8.01(e)(i) or (ii) after the Board Transition Date shall require the
         affirmative vote of a majority of the Board and a majority of the
         Independent Directors; or

         part of the Company which has not been cured and (i) Purchaser shall
         have failed to commence the Offer within the time required by
         Regulation 14D under the Exchange Act, (ii) the Offer shall have been

         Agreement pursuant to Section 8.01 hereof, this Agreement shall
         forthwith become void, without liability on the part of any party
         hereto except as provided in this Section 8.02 and Sections 6.03(b)
         and 9.09 and the last sentence of Section 1.02, and except that
         nothing herein shall relieve any party from liability for any breach
         of this Agreement. Notwithstanding the foregoing, neither Parent or
         Purchaser, on the one hand, nor the Company, on the other hand, shall
         have any rights with respect to the recovery of expenses, except as
         provided for in Sections 8.02(b)(i) and 8.02(b)(ii), respectively.

         Company shall promptly reimburse Parent for all out-of-pocket expenses
         of Parent and its subsidiaries, up to an amount of $100,000 (which
         $100,000 limit shall not apply in the event of a breach by the Company

         pursuant to Section 8.01(e)(i), 8.01(e)(ii) or 8.01(f)(i), then Parent
         shall promptly reimburse the Company for all out-of-pocket expenses of
         Company and its subsidiaries, up to an amount of $100,000, incurred in
         connection with the transactions contemplated hereby. Nothing herein
         shall limit the Company's right under Section 8.02(a) to pursue
         remedies for breach of this Agreement.

                  (iii) If Parent or Purchaser shall have terminated this
         Agreement pursuant to Section 8.01(d)(iii) or the Company shall have
         terminated this Agreement pursuant to Section 8.01(e)(iii), then in
         any such case the Company shall promptly, but in no event later than
         two business days after the date of such termination, pay Parent a
         termination fee of $400,000 and shall have no obligation to pay any

         to any party who shall be in material breach of its obligations
         hereunder. For purposes of this clause (iv), Parent and Purchaser

Shares shall be deemed appropriately modified).

                                       to

                         Agreement and Plan of Merger*

         Conditions of the Offer. Notwithstanding any other provisions of the
Offer, and in addition to (and not in limitation of) Purchaser's rights to
extend and amend the Offer at any time in its sole discretion (subject to the

payment (whether or not the Shares have theretofore been accepted for payment),
or pay for, and may delay the acceptance for payment of, or the payment for,
any tendered Shares, and may terminate the Offer and not accept for payment any
Shares if (i) there are not validly tendered and not withdrawn prior to the

number of then outstanding Shares (the "Minimum Condition"), (ii) all
regulatory approvals required to consummate the Offer and the Merger shall have
been obtained and shall remain in full force and effect and all statutory

conditions exist:

                  (a) there shall be pending any action, investigation,

         agency which seeks to (i) prohibit the making or consummation of the
         Offer or the Merger or (ii) restrain or prohibit the performance of
         the Merger Agreement; (iii) seeks to impose limitations on the ability
         of Purchaser or to render Purchaser unable to accept payment, pay for
         or purchase some or all of the Shares pursuant to the Offer or Merger;
         (iv) seeking to restrain or prohibit Parent's ownership or operation
         of all or any portion of the business and assets of the Company and

         and its subsidiaries; (iv) seeking to impose limitations on the
         ability of Parent and its affiliates to exercise full voting rights or

         have a Material Adverse Effect; or

                  (b) there is in effect any order, decree or injunction
         (whether preliminary, final or appealable, other than a temporary
         restraining order) issued by a court or governmental authority of

                  (c) there shall have been any statute, rule, regulation,
         injunction, order or decree proposed, enacted or promulgated or any
         similar action taken or deemed applicable to the Offer or the Merger
         which prohibits consummation of the Offer or the Merger; or

                  (d) there shall be in effect a banking moratorium or any
         suspension of payments in respect of banks in the United States
         (whether or not mandatory); or

                  (e) Purchaser shall discover that any representation or
         warranty made by the Company in the Merger Agreement is untrue at the
         time such representation or warranty was made or shall not be true and
         correct as of the date of consummation of the Offer (except for those
         representations and warranties made as of a particular date which need
         only be true and correct as of such date), except where the failure to
         be so true and correct would not have a Material Adverse Effect; or

                  (f) there shall have been a breach in any material respect by
         the Company of any of its covenants or agreements contained in the
         Merger Agreement, except for any such breaches that would not have a
         Material Adverse Effect; or

                  (g) the Merger Agreement shall have been terminated in
         accordance with its terms;

                  (h) any person shall have entered into a definitive agreement
         or an agreement in principal with the Company regarding an Alternative
         Acquisition; or

                  (i) the Company's Board of Directors will have withdrawn or
         modified (including by amendment of the Schedule 14D-9) in a manner
         adverse to Parent or Purchaser its approval or recommendation of the
         Offer, the Merger Agreement or the Merger, will have recommended to
         the Company's stockholders another offer or will have adopted any
         resolution to effect any of the foregoing which, in the sole judgment
         of Purchaser in any such case, and regardless of the circumstances
         (including any action or omission by Purchaser) giving rise to any
         such condition, makes it inadvisable to proceed with such acceptance
         or payment.

         The foregoing conditions are for the sole benefit of Purchaser and may
be asserted by Purchaser regardless of the circumstances giving rise to such
condition or may be waived by Purchaser in whole or in part at any time and
from time to time in its sole discretion, subject in each case to the terms of
the Merger Agreement. The failure by Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right and each
such right shall be deemed an ongoing right and may be asserted at any time and
from time to time.

purchase Shares granted by the Company, and (iii) redeem the outstanding shares

         4.1 LIMITATION OF LIABILITY. Escrow Agent will not be bound by the

<PAGE>   4

collect and disburse income from and deliver the Escrowed Funds, as herein
provided. Escrow Agent will not in any way be required to determine whether or
not the terms and conditions of the Agreement and Plan of Merger have been
complied with by the parties. Escrow Agent's duties are only such as are
specifically provided herein and are administrative, not discretionary. Escrow
Agent shall incur no liability whatsoever to Company, Parent or Purchaser except
for gross negligence or wilful misconduct. Escrow Agent shall have no
responsibility hereunder other than to follow faithfully the instructions herein
contained or such further supplemental instructions as Company and Purchaser may
collectively provide. Escrow Agent shall not be subject to liability with
respect to losses suffered from investment of funds in the Escrowed Funds,
except for the safekeeping of the securities in which said funds are invested
and collection of interest thereon. Escrow Agent may consult with counsel and
shall be fully protected in any action taken in good faith in accordance with
such advice. Escrow Agent shall be fully protected in acting in accordance with
any written instructions given to it hereunder and reasonably believed by it to
have been executed by the proper parties. Escrow Agent shall not be liable for
interest on the Escrowed Funds except as provided herein.

         4.2 FEES AND EXPENSES. The Escrow Agent shall charge a fee for its
services hereunder as set forth in SCHEDULE I hereto, Parent and Purchaser
jointly and severally agree to pay all reasonable expenses of Escrow Agent,
including its attorney's fees and expenses, which it may incur in connection
with the performance of its duties under this Escrow Agreement or under the
indemnity provided in Section 4.7. To the extent not otherwise so paid, such
fees and expenses will be chargeable to the Escrowed Funds in existence when the
fees are earned or the expense incurred. Escrow Agent shall notify Company and
Purchaser of the amount to be chargeable pursuant to the preceding sentence, but
shall not be required to collect such amount from Parent or Purchaser; provided
that the failure of Escrow Agent to collect such amount shall not relieve Parent
or Purchaser of their obligations to pay such amounts, which obligations may be
enforced by Company.

         4.3 SUCCESSOR ESCROW AGENT. Escrow Agent may resign at any time by
giving written notice thereof to Company and Purchaser and may be removed at any
time by Company and Purchaser giving joint written notice thereof to Escrow
Agent; PROVIDED, HOWEVER, that any such resignation or removal shall not become
effective until a successor escrow agent shall have been appointed as provided
herein and shall have accepted such appointment in writing upon the resignation
or removal of Escrow Agent. A successor Escrow Agent will be appointed by joint
agreement of Company and Purchaser; PROVIDED, HOWEVER, that in the event no
successor Escrow Agent is appointed by mutual agreement of Company and Purchaser
within ten days after such resignation or removal, Company shall promptly
appoint the successor Escrow Agent, which successor shall be a bank or trust
company organized under the laws of the United States having reported capital
and surplus of not less than $100,000,000. Any such successor escrow agent shall
deliver to Escrow Agent, Company and Purchaser a written instrument accepting
such appointment hereunder, and thereupon it shall succeed to all of the rights,

pursuant to the terms of this Escrow Agreement. If an instrument of acceptance
by a successor escrow agent shall not have been delivered to Escrow Agent within
30 days after the giving of such notice of resignation, the resigning Escrow
Agent or Company or Purchaser, may at the expense of Company and Purchaser,
petition any court of competent jurisdiction for the appointment of a successor
escrow agent.

         4.4 DISPUTES. It is understood and agreed that, should any dispute
arise with respect to the payment and/or ownership or right of possession of the
Escrowed Funds, Escrow Agent is authorized and directed to retain in its
possession, without liability to anyone, all or any part of the Escrowed Funds
until such dispute shall have been settled either by mutual agreement by the
parties concerned or by the final order, decree or judgment of a court or other
tribunal of competent jurisdiction in the United States of America and time for
appeal has expired and no appeal has been perfected as so certified by the
parties. Escrow Agent shall be under no duty whatsoever to institute or defend
any such proceedings.

         4.5 ESCROW AGENT NOT REQUIRED TO INSTITUTE ACTION. Escrow Agent shall
not be required to institute or defend, except in the case of Escrow Agent's
wilful misconduct or gross negligence, any action or legal process involving any
matter referred to herein which in any manner affects it or its duties or
liabilities hereunder. In the event Escrow Agent shall institute or defend any
such action or legal process, it shall do so only upon receiving full indemnity
in an amount and of such character as it shall require, against any and all
claims, liabilities, judgments, attorneys' fees and other expenses of every kind
in relation thereto, except in the case of its own wilful misconduct or gross
negligence.

         4.6 INTERPLEADER. If any two parties, whether or not they are parties
to this Escrow Agreement, shall be in disagreement about the interpretation of
this Escrow Agreement, or about the rights and obligations, or the propriety, of
any action contemplated by Escrow Agent hereunder, or if any other dispute shall
arise hereunder, or if Escrow Agent otherwise has any doubts as to the proper
disposition of funds or any execution of any of its duties hereunder, Escrow
Agent may, at its sole discretion, file an action in interpleader to resolve
such disagreement in any Delaware State court, or any Federal Court of the
United States of America, sitting in Delaware. Escrow Agent shall be indemnified
for all costs, including reasonable attorneys' fees and expenses, and shall be
fully protected in suspending all or part of its activities under this Escrow
Agreement until a final judgment in the interpleader action is received.

         4.7 INDEMNIFICATION. Company, Parent and Purchaser, jointly and
severally, shall hold Escrow Agent harmless and indemnify Escrow Agent against
any loss, liability, expenses (including attorney's fees and expenses), claim or
demand arising out of or in connection with the performance of its obligations
in accordance with the provisions of this Escrow Agreement, except for gross
negligence or wilful misconduct of Escrow Agent; PROVIDED, HOWEVER, that Company
shall have no liability for any payments which are due to Escrow Agent pursuant
to Section 4.2 hereof. The foregoing indemnities in this paragraph shall survive
the resignation or removal of Escrow Agent or the termination of this Escrow
Agreement.

conditions of this Agreement, each of the parties hereto agrees to use all
reasonable best efforts to take, or cause to be taken, all actions and to do,
or cause to be done, all things necessary, proper or advisable under applicable
laws and regulations and which may be required under any agreements, contracts,
commitments, instruments, understandings, arrangements or restrictions of any
kind to which such party is a party or by which such party is governed or
bound, to consummate and make effective the transactions contemplated by this
Agreement.


           SECTION 6.4. Specific Performance. The parties acknowledge and agree
that performance of their respective obligations hereunder will confer a unique
benefit on the other and that a failure of performance will not be compensable
by money damages. The parties therefore agree that this Shareholder Agreement
shall be specifically enforceable and that specific enforcement and injunctive
relief shall be available to the Parent, Purchaser or the Stockholder for any
breach by the other party or parties of any agreement, covenant or
representation hereunder.

           SECTION 6.5. Notices. All notices, requests, claims, demands and
other communications hereunder shall be deemed to have been duly given when
delivered in person, by telecopy, or by registered or certified mail (postage
prepaid, return receipt requested) to such party at its address set forth on
the signature page hereto.


           SECTION 6.6. Survival of Representations and Warranties. All
representations and warranties contained in this Agreement shall survive
delivery of and payment for the Shares pursuant to Section 1.2 hereof. None of
the representations and warranties contained in this Agreement shall survive
the acceptance for payment and payment for the Shares pursuant to the Offer.


           SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer
or (ii) Purchaser amends the Offer to (w) reduce the Offer Price to less than
$8.79 in cash, net to the sellers, (x) reduce the number of shares of Company
Common Stock subject to the Offer, (y) change the form of consideration payable
in the Offer or (z) amend or modify any term or condition of the Offer in a
manner adverse to the stockholders of the Company (other than insignificant
changes or amendments or other than to waive any condition). This Agreement
will also terminate upon the later of (i) the Merger Agreement or (ii)
termination of the Offer or any revised Offer if Purchaser notifies Stockholder
of its intent to continue its Offer or a revised Offer within 2 business days
after termination of the Merger Agreement.


           SECTION 6.8. Successors and Assigns. The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns; provided, however, that Purchaser
may assign its rights and obligations to another wholly-owned subsidiary of the
Parent which is the assignee of Purchaser's rights under the Merger Agreement;
and provided further that except as set forth in the prior clause, a party may
not assign, delegate or otherwise transfer any of its rights or obligations
under this Agreement without the consent of the other parties hereto and any
purported assignment, delegation or transfer without such consent shall be null
and void.

           SECTION 6.9. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to
the principles of conflicts of laws thereof.


           SECTION 6.10. Counterparts; Effectiveness. This Agreement may be
signed in any number of counterparts, each of which shall be an original, with
the same effects as if the signatures thereto and thereof were upon the same
instrument. This Agreement shall become effective when each party hereto shall
have received counterparts hereof signed by all of the other parties hereto.


           SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in
its capacity as the record holder and beneficial owner of the Shares and
nothing herein shall limit or affect any actions taken by the Stockholder in
his or her capacity as an officer, director, partner, employee or affiliate of
the Company and no such actions shall be deemed a breach of this Agreement.

           SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of
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 are 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 shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in a mutually
acceptable manner in order that the transactions be consummated as originally
contemplated to the fullest extent possible. To the extent that any provision
of this Agreement and the Merger Agreement conflict, the provisions of the
Merger Agreement shall control.
