To the Holders of Common Stock
of Optical Security Group, Inc.:

                                  INTRODUCTION

    Applied Opsec Corporation, a Colorado corporation (the "Purchaser") and a
wholly-owned subsidiary of Applied Holographics PLC, a public limited company
incorporated and existing under the laws of England and Wales ("Parent"), is
offering to purchase all outstanding shares (the "Shares") of common stock, par
value $.005 per share ("Common Stock"), of Optical Security Group, Inc., a
Colorado corporation (the "Company"), at $7.00 per Share (the "Offer Price"),
net to the seller, in cash, upon the terms and subject to the conditions set
forth in this Offer to Purchase dated December 6, 1999 and in the related Letter
of Transmittal (which, together with any amendments or supplements thereto,
collectively constitute the "Offer").

    If you have Shares registered in your name that you tender directly, you
will not be obligated to pay brokerage fees or commissions or, except as set
forth in Instruction 6 of the Letter of Transmittal, transfer taxes on the
purchase of Shares pursuant to the Offer. If you hold your Shares through a
broker or bank, you should consult with them to determine if there are any fees
applicable to a tender of the Shares. The Purchaser will pay all fees and
expenses of Wilmington Trust Company, which is acting as the Depositary (the
"Depositary") and MacKenzie Partners, Inc., which is acting as Information Agent
(the "Information Agent"), incurred in connection with the Offer. See
Section 16.

    THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER AND
THE MERGER (AS DEFINED BELOW) AND DETERMINED THAT THE TERMS OF THE OFFER AND THE
MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE
COMPANY, AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF THE COMPANY ACCEPT THE
OFFER AND TENDER THEIR SHARES.

    The Company has advised the Purchaser that Wasserstein Perella & Co., Inc.
("Wasserstein Perella") has delivered to the board of directors of the Company
its written opinion dated November 29, 1999 to the effect that, subject to and
based upon the matters described in the opinion, as of the date of such opinion,
the $7.00 in cash per Share to be received by the holders of Shares pursuant to
the Offer and the Merger is fair to such holders from a financial point of view.
That opinion is set forth in full as an exhibit to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which is being mailed to you with this Offer to Purchase. YOU ARE URGED TO, AND
SHOULD, READ SUCH OPINION CAREFULLY IN ITS ENTIRETY.

    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 THAT WOULD CONSTITUTE AT LEAST A MAJORITY OF THE
OUTSTANDING SHARES (DETERMINED AS OF THE EXPIRATION DATE ON A FULLY DILUTED
BASIS, TAKING INTO ACCOUNT ALL SHARES ISSUABLE ON EXERCISE OR CONVERSION OF ALL
OPTIONS, WARRANTS AND ANY OTHER RIGHTS TO ACQUIRE SHARES OUTSTANDING ON THE
EXPIRATION DATE) (THE "MINIMUM CONDITION"). THE 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, TO WAIVE OR REDUCE THE MINIMUM CONDITION AND TO ELECT TO PURCHASE,
PURSUANT TO THE OFFER, LESS THAN THE NUMBER OF SHARES REQUIRED TO SATISFY THE
MINIMUM CONDITION. SEE SECTIONS 1 AND 14.

    The Company has informed the Purchaser that, as of November 30, 1999, there
were 6,202,425 Shares issued and outstanding and 3,713,616 shares reserved for
issuance upon the exercise of outstanding options, warrants, and other rights to
acquire Shares (including 333,333 Shares issuable by the Company in connection
with the Bridgestone Acquisition (see Section 11), and excluding 426,154 Shares
issuable upon exercise of the Company's $6.50 Senior Subordinated Convertible
Debentures, and 309,052 Shares issuable upon exercise of certain warrants and
options, on the assumption that such securities will either be cashed out or
terminated prior to exercise). Accordingly, based on the foregoing assumptions,
the Minimum Condition will be satisfied if at least 4,958,021 Shares, or
approximately 80% of the outstanding Shares as

                                       1
<PAGE>
of November 30, 1999, are validly tendered and not withdrawn prior to the
Expiration Date. Once the Minimum Condition has been satisfied and the Purchaser
accepts for payment Shares tendered pursuant to the Offer, the Purchaser will be
able to elect a majority of the members of the Company's board of directors and,
if such amount of shares also constitutes at least 90% of all Shares outstanding
at such time, to effect the Merger without the affirmative vote of any other
stockholder of the Company.

    The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of November 30, 1999 (the "Merger Agreement"), among Parent, the Purchaser
and the Company, pursuant to which, following the consummation of the Offer and
the satisfaction or waiver of certain conditions, the Purchaser will be merged
with and into the Company, with the Company surviving the merger (as such, the
"Surviving Corporation") as a subsidiary of Parent (the "Merger"). In the
Merger, each Share issued and outstanding immediately prior to the Merger (other
than Shares (1) owned or held in treasury by the Company, (2) owned by Parent or
the Purchaser, (3) remaining outstanding held by any subsidiary of the Company
or Parent or (4) owned by stockholders, if any, who are entitled to and who
properly exercise dissenters' rights under Colorado law) will be converted into
the right to receive in cash, without interest, the per Share price paid in the
Offer (the "Merger Consideration"). See Section 12.

    The Merger is subject to a number of conditions, including approval by
stockholders of the Company, if such approval is required by applicable law. If
the Purchaser acquires 90% or more of the outstanding Shares pursuant to the
Offer or otherwise, the Purchaser will effect the Merger pursuant to the
short-form merger provisions of the Colorado Business Corporation Act (the
"CBCA"), without prior notice to, or any action by, any other stockholder of the
Company. See Section 12.

    The Merger Agreement is more fully described in Section 12. Certain Federal
income tax consequences of the sale of Shares pursuant to the Offer and the
exchange of Shares for the Merger Consideration pursuant to the Merger are
described in Section 5.

                                THE TENDER OFFER

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 any such extension or
amendment), the Purchaser will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 3. The term "Expiration Date" means 12:00 noon, New York
City time, on Friday, January 7, 2000, unless the Purchaser shall have extended
the period of time during which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by the Purchaser, shall expire.

    Subject to applicable rules and regulations of the Commission, the Purchaser
expressly reserves the right, in its sole discretion, at any time and from time
to time, and regardless of whether or not any of the events set forth in
Section 14 hereof shall have occurred or shall have been determined by the
Purchaser to have occurred, (1) to extend the period of time during which the
Offer is open, and thereby delay acceptance for payment of and the payment for
any Shares, by giving oral or written notice of such extension to the Depositary
and (2) to amend the Offer in any other respect by giving oral or written notice
of such amendment to the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE
PAID ON THE PURCHASE PRICE OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS
OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

    If by 12:00 noon, New York City time, on Friday, January 7, 2000 (or any
other date or time then set as the Expiration Date), any or all conditions to
the Offer have not been satisfied or waived, the Purchaser reserves the right
(but shall not be obligated), subject to the terms and conditions contained in
the Merger Agreement and to the applicable rules and regulations of the
Commission, (1) to terminate the Offer and not accept for payment any Shares and
return all tendered Shares to tendering stockholders, (2) to waive

                                       2
<PAGE>
one or more of the unsatisfied conditions and, subject to complying with the
terms of the Merger Agreement and the applicable rules and regulations of the
Commission, accept for payment and pay for all Shares validly tendered prior to
the Expiration Date and not theretofore withdrawn, (3) to extend the Offer and,
subject to the right of stockholders to withdraw Shares until the Expiration
Date, retain the Shares that have been tendered during the period or periods for
which the Offer is extended or (4) to amend the Offer.

    There can be no assurance that the Purchaser will exercise its right to
extend the Offer. Any extension, waiver, amendment or termination will be
followed as promptly as practicable by public announcement. In the case of an
extension, Rule 14e-l(d) under the Securities Exchange Act of 1934 (the
"Exchange Act") requires that the announcement be issued no later than
9:00 a.m., New York City time, on the next business day after the previously
scheduled Expiration Date in accordance with the public announcement
requirements of Rule 14d-4(c) under the Exchange Act. Subject to applicable law
(including Rules 14d-4(c) and 14d-6(d) under the Exchange Act which require that
any material change in the information published, sent or given to stockholders
in connection with the Offer be promptly disseminated to stockholders in a
manner reasonably designed to inform stockholders of such change), and without
limiting the manner in which the Purchaser may choose to make any public
announcement, the Purchaser currently intends to make such public announcement
by issuing a press release to the Dow Jones News Service and making any
appropriate filing with the Commission.

    Pursuant to the Merger Agreement, the Purchaser may, without the prior
consent of the Company, extend the Offer, particularly, but not exclusively
(1) if at the Expiration Date any of the conditions to the Purchaser's
obligations to accept Shares for payment are not satisfied or waived, until such
time as such conditions are satisfied or waived, (2) for any period required by
any rule, regulation, interpretation or position of the Commission or the staff
thereof applicable to the Offer or any period required by applicable law and
(3) on one or more occasions for an aggregate period of not more than 10
business days beyond the latest expiration date that would otherwise be
permitted under clause (1) or (2) of this sentence, if on such expiration date
there shall not have been tendered at least 90% of the outstanding Shares. For
purposes of the Offer, a "business day" means any day other than a Saturday,
Sunday or a federal holiday and consists of the time period from 12:01 a.m.
through 12:00 Midnight, New York City time.

    If the Purchaser extends the Offer or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its acceptance for
payment of or payment for Shares or it is unable to pay for Shares pursuant to
the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer, the Depositary may retain tendered Shares on behalf of the
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 the Purchaser to delay the payment for Shares that the
Purchaser has accepted for payment is limited by Rule 14e-1 under the 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 such bidder's offer.

    If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-l under the
Exchange Act. The minimum period during which an 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 the changed terms or information. With
respect to a change in price or a change in the percentage of securities sought,
a minimum period of 10 business days is generally required to allow for adequate
dissemination to stockholders.

                                       3
<PAGE>
    CONSUMMATION OF THE OFFER IS CONDITIONED UPON SATISFACTION OF THE MINIMUM
CONDITION AND THE OTHER CONDITIONS SET FORTH IN SECTION 14. Subject to the terms
and conditions contained in the Merger Agreement, the Purchaser reserves the
right (but shall not be obligated) to waive any or all such conditions. The
Company has provided the Purchaser with the Company's stockholder lists and
security position listings for the purpose of disseminating the Offer to holders
of the Shares. This Offer to Purchase, the related Letter of Transmittal and
other relevant materials will be mailed by the Purchaser to record holders of
Shares and will be furnished by the Purchaser 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

    VALID TENDER.  For a stockholder to tender Shares validly pursuant to the
Offer, either (1) a properly completed and duly executed Letter of Transmittal
(or facsimile thereof), together with any required signature guarantees, or in
the case of a book-entry transfer, an Agent's Message (as defined in the second
succeeding paragraph), and any other documents required by the Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration Date
and either certificates for tendered Shares must be received by the Depositary
at one of such addresses or such Shares must be delivered pursuant to the
procedure for book-entry transfer set forth below (and a Book-Entry Confirmation
(as defined in the next paragraph) received by the Depositary), in each case,
prior to the Expiration Date, or (2) the tendering stockholder must comply with
the guaranteed delivery procedure set forth below.

    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 within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Shares by causing the
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account in accordance with the Book-Entry Transfer Facility's procedures for
such transfer. However, although delivery of Shares may be effected through
book-entry transfer into the Depositary's account at the Book-Entry Transfer
Facility, the Letter of Transmittal (or facsimile thereof), properly completed
and duly executed, with any required signature guarantees, or an Agent's
Message, and any other required documents, must, in any case, be transmitted to,
and received by, the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date, or the tendering
stockholder must comply with the guaranteed delivery procedure described below.
The confirmation of a book-entry transfer of Shares into the Depositary's
account at the Book-Entry Transfer Facility as described above is referred to
herein as a "Book-Entry Confirmation." DELIVERY OF THE LETTER OF TRANSMITTAL OR
ANY OTHER REQUIRED DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE
WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY
TO THE DEPOSITARY.

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

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

                                       4
<PAGE>
    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal if (1) the Letter of Transmittal is signed by the registered holder
(which term, for purposes of this Section, includes any participant in the
Book-Entry Transfer Facility's system whose name appears on a security position
listing as the owner of the Shares) of Shares tendered therewith unless such
registered holder has completed either the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" on the Letter
of Transmittal or (2) such Shares are tendered for the account of a financial
institution (including most commercial banks, savings and loan associations and
brokerage houses) that is a participant in the Security Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Guarantee
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
the Letters of Transmittal must be guaranteed by an Eligible Institution. See
Instructions 1 and 5 to the Letter of Transmittal. If the certificates for
Shares are registered in the name of a person other than the signer of the
Letter of Transmittal, or if payment is to be made, or certificates for Shares
not tendered or not accepted for payment are to be issued, to a person other
than the registered holder of the certificates surrendered, the tendered
certificates must be endorsed or accompanied by appropriate stock powers, in
either case, signed exactly as the name or names of the registered holders or
owners appear on the certificates, with the signatures on the certificates or
stock powers guaranteed as aforesaid. See Instruction 5 to the Letter of
Transmittal.

    GUARANTEED DELIVERY.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met:

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

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

        (3) the certificates for all tendered Shares, in proper form for
    transfer (or a Book-Entry Confirmation with respect to such Shares),
    together with a properly completed and duly executed Letter of Transmittal
    (or facsimile thereof), with any required signature guarantees, 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 trading days after the date of execution of such Notice of Guaranteed
    Delivery. A "trading day" is any day on which the New York Stock
    Exchange, Inc. (the "NYSE") is open for business.

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

    Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (1) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (2) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, and (3) any other documents required by the Letter of Transmittal.
Accordingly, tendering stockholders may be paid at different times depending
upon when certificates for Shares or Book-Entry Confirmations are actually
received by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE
PURCHASE PRICE OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY
EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

                                       5
<PAGE>
    The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering stockholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

    APPOINTMENT.  By executing a Letter of Transmittal, the tendering
stockholder will irrevocably appoint designees of the Purchaser as such
stockholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after November 30, 1999. All such proxies shall be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such stockholder as provided herein. Upon such
acceptance for payment, all prior powers of attorney, proxies and consents given
by such stockholder with respect to such Shares or other securities or rights
will, without further action, be revoked and no subsequent powers of attorney,
proxies or consents may be given (and, if given, will not be deemed effective).
The designees of the Purchaser will thereby be empowered to exercise all voting
rights with respect to such Shares or other securities or rights in respect of
any annual, special or adjourned meeting of the Company's stockholders, or
otherwise, and may execute any written consent, and may otherwise act as an
attorney-in-fact and proxy concerning any matter as they in their sole
discretion deem proper. The Purchaser reserves the right to require that, in
order for Shares to be deemed validly tendered, immediately upon the Purchaser's
acceptance for payment of such Shares, the Purchaser must be able to exercise
full voting rights with respect to such Shares and other securities or rights,
including voting at any meeting of stockholders then scheduled.

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

    BACKUP FEDERAL INCOME TAX WITHHOLDING.  In order to avoid "backup
withholding" of federal income tax on payments of cash pursuant to the Offer, a
stockholder surrendering Shares in the Offer must, unless an exemption applies,
provide the Depositary with such Stockholder's correct Taxpayer Identification
Number ("TIN") on a Substitute Form W-9 and certify under penalty of perjury
that such TIN is correct and that such stockholder is not subject to backup
withholding. If a stockholder does not provide its correct TIN or fails to
provide the certifications described above, the Internal Revenue Service ("IRS")
may impose a penalty on such stockholder and payment of cash to such stockholder
pursuant to the Offer may be subject to backup withholding of 31%. All
stockholders surrendering Shares pursuant to the Offer should complete and sign
the main signature form and the Substitute Form W-9 included as part of the
Letter of Transmittal to provide the information and certification necessary to
avoid backup withholding (unless an applicable exemption exists and is proven in
a manner satisfactory to the Purchaser and the Depositary). Foreign stockholders
should complete and sign the main signature form and a Form W-8, Certificate of
Foreign Status, a copy of which may be obtained from the Depositary, in order to
avoid

                                       6
<PAGE>
backup withholding. See instruction 9 to the Letter of Transmittal and
"Important Tax Information" in the Letter of Transmittal.

3.  WITHDRAWAL RIGHTS

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

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

    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Parent, the Depositary, the Information Agent 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 FOR SHARES

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will accept for payment and, promptly after the
Expiration Date, will pay for all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 3. Any
determination concerning the satisfaction of such terms and conditions will be
within the sole discretion of the Purchaser, and such determination will be
final and binding on all tendering stockholders. See Sections 1 and 14. The
Purchaser expressly reserves the right, in its sole discretion, to delay
acceptance for payment of or payment for Shares in order to comply with any
applicable law. Any such delays will be effected in compliance with
Rule 14e-1(c) under the Exchange Act (relating to the Purchaser's obligation to
pay for or return tendered Shares promptly after the termination or withdrawal
of the Offer).

    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (1) certificates for
such Shares (or timely Book-Entry Confirmation of a transfer of such Shares as
described in Section 2), (2) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees and
(3) any other documents required by the Letter of Transmittal. The per Share
consideration paid to any stockholder pursuant to the Offer will be the highest
per Share consideration paid to any other stockholder pursuant to the Offer.

                                       7
<PAGE>
    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn, if and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Shares. Payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the Purchaser
and transmitting payment to tendering stockholders. UNDER NO CIRCUMSTANCES WILL
INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE PAID BY THE
PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.

    If the 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 the Purchaser's rights under
the Offer (but subject to compliance with Rule 14e-1(c) under the Exchange Act,
which requires that a tender offeror pay the consideration offered or return the
tendered securities promptly after the termination or withdrawal of a tender
offer), the Depositary may, nevertheless, on behalf of the Purchaser, retain
tendered Shares. Any 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 because of an
invalid tender or otherwise, certificates for any such Shares will be returned,
without expense to the tendering stockholder (or, in the case of Shares
delivered by book-entry transfer of such Shares into the Depositary's account at
the Book-Entry Transfer Facility pursuant to the procedure set forth in
Section 2, such Shares will be credited to an account maintained at the
Book-Entry Transfer Facility), as promptly as practicable after the expiration
or termination of the Offer.

    The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Parent, or to one or more direct or indirect wholly
owned subsidiaries of Parent, the right to purchase Shares tendered pursuant to
the Offer. Any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer and will in no way prejudice the rights of tendering
stockholders to receive payment for Shares validly tendered and accepted for
payment pursuant to the Offer.

5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The receipt of cash pursuant to the Offer or the Merger will constitute a
taxable transaction for federal income tax purposes under the Internal Revenue
Code of 1986, as amended (the "Code"), and may also constitute a taxable
transaction under applicable state, local, foreign and other tax laws. As a
result, a tendering stockholder will generally recognize gain or loss for
Federal income tax purposes in an amount equal to the difference between the
amount of cash received by the stockholder pursuant to the Offer or the Merger
and such stockholder's aggregate adjusted tax basis in the Shares tendered and
purchased pursuant to the Offer (or canceled pursuant to the Merger). Gain or
loss will be calculated separately for each block of Shares tendered and
purchased pursuant to the Offer (or canceled pursuant to the Merger). If
tendered Shares are held by a tendering stockholder as capital assets, any gain
or loss recognized by the tendering stockholder will constitute capital gain or
loss, and will constitute long-term capital gain or loss if the tendering
stockholder held the underlying Shares for more than 12 months as of the date of
disposition. There are limits on the deductibility of capital losses.

    A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals) that tenders Shares
may be subject to backup withholding at a rate of 31% unless the stockholder
provides its correct TIN (or certifies that it is awaiting a TIN) and certifies
as to no loss of exemption from backup withholding and otherwise complies with
the applicable requirements of the backup withholding rules. A stockholder that
does not furnish its correct TIN in the prescribed manner or that does not
otherwise establish a basis for an exemption from backup withholding may be
subject to a penalty imposed by the IRS, and the gross proceeds of the Offer or
the Merger payable to such

                                       8
<PAGE>
stockholder may be subject to backup withholding at a rate of 31%. Each
stockholder should complete and sign the Substitute Form W-9 included as part of
the Letter of Transmittal so as to provide the information and certification
necessary to avoid backup withholding.

    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 MAY NOT BE APPLICABLE WITH RESPECT TO SHARES
RECEIVED PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION OR WITH RESPECT TO 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 A
HOLDER OF SHARES IN LIGHT OF SUCH PERSON'S 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.

    On November 29, 1999, the last full day of trading before the public
announcement of the execution of the Merger Agreement, the reported last sale
price of the Shares on The Nasdaq SmallCap Stock Market(SM) was $5.63 per Share.
On December 2, 1999, the reported last sale price of the Shares on The Nasdaq
SmallCap Stock Market(SM) was $6.75 per Share. STOCKHOLDERS ARE URGED TO OBTAIN
CURRENT MARKET QUOTATIONS FOR THE SHARES.

    According to the Company's Annual Report on Form 10-KSB for the fiscal year
ended March 31, 1999 (the "Form 10-KSB"), the Company has not paid cash
dividends on Common Stock to date and does not plan to pay cash dividends to its
common stockholders in the foreseeable future.

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

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

    MARKET FOR SHARES.  Depending upon the number of Shares purchased pursuant
to the Offer, the Shares may no longer meet the requirements of the National
Association of Securities Dealers, Inc. (the "NASD") for continued inclusion in
The Nasdaq SmallCap Stock Market(SM). According to published guidelines for the
Nasdaq SmallCap Stock Market(SM), the Shares might no longer be eligible for
quotation on the Nasdaq SmallCap Stock Market(SM) if, among other things, either
(1) the Company's net tangible assets were less than $2,000,000, the Company's
market capitalization was less than $35,000,000, and the Company's net income
(in latest fiscal year or 2 of last 3 fiscal years) was less than $500,000, or
(2) the number of Shares publicly held was fewer than 500,000, there were fewer
than 300 holders of round lots, the aggregate market value of publicly held
Shares was less than $1,000,000, or there were fewer than two registered and
active market makers for the Shares. If these standards are not met, the Shares
might nevertheless continue to be included in The Nasdaq Stock Market with
quotations published in the Nasdaq "additional list" or in one of the "local
lists," but if the number of holders of the Shares were to fall below 300, or if
the number of publicly held Shares were to fall below 100,000 or there were not
at least two registered and active market makers for the Shares, the NASD's
rules provide that the Shares would no longer be "qualified" for Nasdaq Stock
Market reporting and The Nasdaq Stock Market would cease to provide any
quotations. Shares held directly or indirectly by directors, officers or
beneficial owners of more than 10% of the Shares are not considered as being
publicly held for this purpose. According to the Company, as of November 26,
1999, there were approximately 831 holders of record of Shares (including one
holder in "street name" representing approximately 800 stockholders) and
6,202,425 Shares were outstanding. If, as a result of the purchase of Shares
pursuant to the Offer, the Shares no longer meet the requirements of the NASD
for continued inclusion in The Nasdaq Stock Market or The Nasdaq SmallCap Stock
Market(SM), as the case may be, the market for Shares could be adversely
affected.

    If the Shares no longer meet the requirements of the NASD for quotation
through any tier of The Nasdaq Stock Market, it is possible that the Shares
would continue to trade in the over-the-counter market and that price quotations
would be reported by other sources. The extent of the public market for the
Shares and the availability of such quotations would depend, however, upon the
number of holders of Shares remaining at such time, the interests in maintaining
a market in Shares on the part of securities firms, the possible termination of
registration of the Shares under the Exchange Act, as described below, and other
factors.

    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
shortswing profit recovery provisions of Section 16(b) of the Exchange Act, the
requirement of furnishing a proxy statement pursuant to Section 14(a) of the
Exchange Act in connection with 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 144A promulgated under the Securities Act of
1933, may be impaired or eliminated. The Purchaser intends to seek to cause the
Company to apply for termination of registration of the Shares under the
Exchange Act as soon after the completion of the Offer as the requirements for
such termination are met.

                                       10
<PAGE>
    If registration of the Shares is not terminated prior to the Merger, then
the Shares will cease to be reported on The Nasdaq Stock 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 currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of the Shares. Depending upon factors
similar to those described above regarding listing and market quotations, it is
possible that, following the Offer, the Shares would no longer constitute
"margin securities" for the purposes of the margin regulations of the Federal
Reserve Board and therefore could no longer be used as collateral for loans made
by brokers. If registration of Shares under the Exchange Act were terminated,
the Shares would no longer be "margin securities."

</TABLE>

    SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN UK GAAP AND US GAAP.  The
consolidated financial statements of Applied Holographics PLC above are prepared
and presented under the historical cost convention in accordance with United
Kingdom generally accepted accounting principles ("UK GAAP"). UK GAAP differs in
certain significant respects from United States generally accepted accounting
principles ("US GAAP"). Certain significant differences between UK GAAP and US
GAAP as they relate to the financial statements of Parent are summarized below.
Such summary should not be construed to be exhaustive. Given the inherent
differences between UK GAAP and US GAAP, the financial statements presented
under UK GAAP are not presented fairly, in all material respects, under US GAAP.
Parent has not quantified these differences, nor prepared consolidated financial
statements under US GAAP, nor undertaken a reconciliation of UK GAAP and US GAAP
financial statements. Had Parent undertaken any such qualification or
preparation or reconciliation, other potentially significant accounting and
disclosure differences may have come to their attention, which are not
identified below. Accordingly, Parent can provide no assurance that the
identified differences in the summary below represent all the principal
differences relating to Parent. Further, no attempt has been made to identify
future differences between UK GAAP and US GAAP as the result of prescribed
changes in accounting standards. Professional bodies that promulgate UK GAAP and
US GAAP have significant projects that could affect future comparisons such as
this one. Finally, no attempt has been made to identify all future differences
between UK GAAP and US GAAP that may affect the financial statements as a result
of transactions or events that may occur in the future.

                                       20
<PAGE>
        (1) CURRENT ASSETS AND LIABILITIES.  Current assets under UK GAAP
    include amounts which fall due after more than one year. Under US GAAP such
    assets would be reclassified as non-current assets. Provisions for
    liabilities and charges under UK GAAP include amounts due within one year
    which would be reclassified to current liabilities under US GAAP.

        (2) COMPENSATION EXPENSE.  Parent has three principal stock compensation
    schemes which result in a UK GAAP to US GAAP accounting difference.

           Under UK GAAP, qualified Save As You Earn (SAYE) schemes which offer
       employees up to a 20% discount on stock prices do not result in
       compensation expense. Under US GAAP, if all other qualifications for a
       non compensatory plan are met, but the plan offers a discount on the
       stock price greater than 15%, the plan is considered compensatory, and
       compensation expense is recognized.

           Under UK GAAP, in a share option scheme no compensation expense is
       recognized upon the issuance of stock options if the exercise price for
       the option is equivalent to, or above, the market price of the stock on
       the date of issue. Under US GAAP, compensation expense is based upon the
       exercise price of the option in comparison to the market price of the
       stock on the measurement date. The measurement date is fixed only when
       both the number of shares to be issued and the exercise price are fixed.

           Under UK GAAP, compensation expense is recognized upon the payment of
       cash under the phantom share option scheme, which pays an employee the
       increase in the market value of specific number of shares. Under US GAAP,
       compensation cost should be recognized over the vesting period and
       measured as the amount by which the quoted market value of the shares
       exceeds the option price, subject to adjustment in future periods for
       changes in the market value prior to exercise of the option.

        (3) DEFERRED TAXATION.  Under UK GAAP, deferred taxation is only
    accounted for the extent that it is probable that a liability or asset will
    arise in the foreseeable future. The calculation of deferred taxation is
    based upon timing differences between taxable and accounting income. Under
    US GAAP, deferred taxation is accounted for on all temporary differences,
    and a valuation allowance is established in respect of deferred taxation
    assets where it is more likely than not that some portion will not be
    realized. Additionally, for US GAAP purposes deferred taxes would be
    provided in respect of US GAAP adjustments to the book basis of assets and
    liabilities.

        (4) JOINT VENTURES.  Under UK GAAP Parent has reflected its interest in
    joint ventures on the basis of proportional consolidation. Under US GAAP,
    investments in joint ventures are generally recorded as a single line in
    accordance with the principles of equity accounting.

        (5) EARNINGS PER ORDINARY SHARE.  Under UK GAAP, a fully diluted
    calculation is provided only if materially dilutive (five per cent) in
    relation to the undiluted amount. Under US GAAP, the calculation of diluted
    earnings per share includes the effect of the assumed exercise of all
    dilutive potential common shares (e.g., outstanding share options and
    warrants as well as convertible debt) that were outstanding during the
    period, unless such exercise would prove to be antidilutive. Furthermore,
    under US GAAP both basic and fully diluted earnings per share must be
    presented on the face of the income statement of public companies.

        (6) CONVERTIBLE SECURITIES.  Under UK GAAP, convertible debt securities
    are classified as liabilities and the accrued interest payable on the
    securities is recorded as interest expense. Under US GAAP, conditions may
    require the convertible securities to be classified within the equity
    section and interest expense to be classified as dividends.

        (7) CASH FLOW STATEMENTS.  The definition of "cash flows" differs
    between UK GAAP and US GAAP. Cash flows under UK GAAP represents increases
    or decreases in "cash", which is comprised of cash in hand and repayable on
    demand and overdrafts. Under US GAAP, cash flow represents increases or
    decreases in "cash and cash equivalents", which include short term, highly
    liquid investments with original maturities of less than 90 days, and
    exclude overdrafts.

                                       21
<PAGE>
        There are also certain differences in classification of items within the
    cash flow statement between UK GAAP and US GAAP. Under UK GAAP, cash flows
    are presented in the following categories: (a) operating activities;
    (b) returns on investments and servicing of finance; (c) taxation;
    (d) capital expenditure and financial investment; (e) acquisitions and
    disposals; (f) equity dividends paid; (g) management of liquid resources;
    and (h) financing. Under US GAAP cash flows are segregated into operating,
    investing and financing activities.

        Cash flows from taxation, returns on investments and servicing of
    finance would be, with the exception of any interest paid but capitalized,
    included as operating activities under US GAAP. The payment of any dividends
    would be included under financing activities and any capitalized interest
    would be included under investing activities for US GAAP purposes.
    Additionally, under US GAAP cash flows from the purchase and sale of
    tangible fixed assets and the sale of debt and equity investments would be
    shown within investing activities.

        (8) DISCLOSURES.  In general, disclosures required under US GAAP are
    more extensive than those required under UK GAAP. For example, under US GAAP
    more detailed disclosures would be required with respect to share options
    (details of all share option schemes and the fair value of share options
    issued), financial instruments (fair value, terms, gains recognized), taxes
    (details of the components of current and deferred income tax expenses and
    deferred tax items, including valuation allowances), and equity (a statement
    of changes in shareholders equity and associated rights).

10.  SOURCE AND AMOUNT OF FUNDS

    The total amount of funds required by the Purchaser to purchase all
outstanding Shares pursuant to the Offer and to pay fees and expenses related to
the Offer and the Merger is estimated to be approximately $64 million. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution which will be made by Parent to the Purchaser.

    Parent intends to provide to the Purchaser the funds required to consummate
the Offer and the Merger by way of a Placing and Open Offer (the "Placing and
Open Offer") of 20,370,370 new ordinary 5 pence shares of Parent (the "New
Ordinary Shares") at 270 pence each, to raise approximately 52.5 million pounds
sterling (US $84 million). The New Ordinary Shares will be listed on the London
Stock Exchange, and will be issued to certain institutional investors and to
Parent's existing stockholders. The Placing and Open Offer is being fully
underwritten by Greig Middleton & Co. Limited ("Greig Middleton").

    The Placing and Open Offer is conditional, inter alia, on the following:

    (1) the prospectus (the "UK Prospectus") relating to the Placing and Open
       Offer being approved by the London Stock Exchange and filed with the

11. CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER

    LOAN AGREEMENT WITH THE COMPANY.  Parent and the Company are parties to a
Loan Agreement dated November 30, 1999 (the "Loan Agreement"). Pursuant to the
terms and conditions set forth in the Loan Agreement, Parent has agreed to lend
to the Company on or before December 10, 1999 an amount not in excess of
$10,000,000 (the "Loan"). The Company shall use the proceeds of the Loan solely
to complete the purchase of 100% of the issued and outstanding capital stock of
Bridgestone Technologies, Inc. and 19.9% of the membership interests of two
associated limited liability companies, Label Systems Acquisition L.L.C. and
Keystone Technologies, L.L.C (the "Bridgestone Transaction"), pursuant to the
Stock Purchase Agreement executed between the Company, Keystone Technologies,
L.L.C., and Kenneth P. Felis, Michael J. Zubretsky, Richard Zucker and Timothy
Dolan, as sellers (the "Bridgestone Agreement"). Subject to acceleration of the
Loan in accordance with the terms of the Loan Agreement, the Loan shall be due
and payable in full in cash on the date (the "Maturity Date) which is the
earliest to occur of (1) December 31, 2000, or (2) any date specified in a
demand notice delivered by Parent to the Company; provided, that such date shall
not be earlier than six months from the date of such demand notice; provided
further, that such demand notice shall not be delivered to the Company prior to
the date of termination of the Merger Agreement, or (3) any date which may be
mutually agreed upon in writing by Parent and the Company. In the event the
Merger is not completed on or before the Maturity Date and the failure to
complete the Merger is not the result of Parent's stockholders failing to
approve the Merger or Parent failing to obtain the financing necessary to
complete the Merger, and so long as Parent has not materially breached any
agreement or other document in connection with the Merger, then a fee of
$1,700,000 shall be due from the Company to Parent on the Maturity Date. The
Loan shall be secured by liens (subject only to existing senior lender liens and
other mutually agreed upon liens) on all assets of the Company and its
subsidiaries located in the United States, whether now owned or hereafter
acquired, pursuant to the terms of the security documents to which the Company
or its subsidiaries located in the United States are a party.

    STOCK OPTION AGREEMENT WITH THE COMPANY.  Immediately after the execution of
the Merger Agreement, the Company executed and delivered a stock option
agreement, dated November 30, 1999 (the "Option Agreement"), pursuant to which
the Company granted to Parent an option to purchase Common Stock under the
conditions set forth below. The Option Agreement is intended to increase the
likelihood that the Merger will be consummated in accordance with the terms of
the Merger Agreement. Consequently, certain aspects of the Option Agreement may
have the effect of discouraging persons who might now or at any other time prior
to the completion of the Merger may be interested in acquiring all of or a
significant interest in the Company from considering or proposing an
acquisition, even if those persons were prepared to offer to pay consideration
to shareholders of the Company in excess of that proposed to be paid by Parent
pursuant to the Merger Agreement.

    The Option Agreement provides for the purchase by Parent of up to 1,234,283
shares (the "Option Shares") of Common Stock, subject to certain anti-dilutive
adjustments, at an exercise price of $7.00 per

                                       23
<PAGE>
share, payable in cash. The Option Shares will in no event exceed 19.9% of the
Common Stock issued and outstanding without giving effect to the issuance of any
Common Stock subject to the Option.

    EXERCISE OF THE COMPANY OPTION.  The Option will become exercisable, in
whole or in part, but only if both an Initial Triggering Event and a Subsequent
Triggering Event occur prior to an Exercise Termination Event. For purposes of
the Option Agreement:

    (1) An "Initial Triggering Event" will occur if one of the following events
       occurs:

       (a) the Company, without Parent's prior written consent, enters into an
           agreement to engage in, or the board of directors of the Company
           recommends that shareholders of the Company approve or accept, an
           Acquisition Transaction,

       (b) the Company, without Parent's prior written consent, authorizes,
           recommends, proposes or publicly announces its intention to
           authorize, recommend or propose to engage in an Acquisition
           Transaction, or the board of directors of the Company publicly
           withdraws or modifies, or publicly announces its intention to
           withdraw or modify, in any manner adverse to Parent, its
           recommendation that its shareholders approve the Merger Agreement,

       (c) the Company terminates the Merger Agreement after receipt of a
           superior proposal from a third party,

       (d) a third party acquires beneficial ownership, or the right to acquire
           beneficial ownership, of 20% or more of the outstanding shares of
           Common Stock,

       (e) a third party makes a BONA FIDE proposal to the Company or its
           shareholders by public announcement, or written communication that
           becomes the subject of public disclosure, to engage in an Acquisition
           Transaction, or

       (f) the Company breaches any covenant or obligation in the Merger
           Agreement after an overture is made by a third party to engage in an
           Acquisition Transaction, and following the breach, Parent would be
           entitled to terminate the Merger Agreement.

(2) As used above in (1), the term "Acquisition Transaction" means:

       (a) a merger or consolidation, or any similar transaction with the
           Company or any of its subsidiaries

       (b) a purchase, lease or other acquisition or assumption of all or
           substantially all of the assets of the Company or any of its
           subsidiaries

       (c) a purchase or other acquisition of securities representing 20% or
           more of the voting power of the Company or any of the Company's
           subsidiaries, or

       (d) any transaction substantially similar to those described in (a) - (c)
           above.

(3) A "Subsequent Triggering Event" will occur if either of the following
    occurs:

       (a) any person acquires beneficial ownership of 30% or more of the
           then-outstanding shares of Common Stock; or

       (b) the Initial Triggering Event described in clause (1)(a) occurs,
           except that the percentage referred to in clause (2)(c) of the
           definition of "Acquisition Transaction" set forth above is 30%.

(4) An "Exercise Termination Event" means the earliest of:

       (a) the effective time of the Merger,

       (b) termination of the Merger Agreement in accordance with its terms if
           the termination occurs prior to the occurrence of an Initial
           Triggering Event, except in the case of the termination of the Merger
           Agreement by Parent as a result of an uncured material breach by the
           Company of any of its representations, warranties, covenants or
           agreements, or

                                       24
<PAGE>
       (c) the date that is 6 months after the termination of the Merger
           Agreement.

    REPURCHASE OF THE COMPANY OPTION.  The Option Agreement also provides that
after the occurrence of a Repurchase Event (as defined below), upon request, the
Company will repurchase the Option and all or any part of the Option Shares
received upon the full or partial exercise of the Option from the holder of
those shares At the Company's option, however, instead of repurchasing the
Option and any Option Shares, the Company may choose to cause any Option Shares
to be registered with the SEC under the Securities Act of 1933, as amended. In
the event that the Company chooses this option, the Option and any Option Shares
will not be repurchased by the Company.

    Any repurchase of the Option will be made at an aggregate price equal to the
amount by which the Market/Offer Price (as defined below) exceeds the option
price multiplied by the number of shares then subject to the Option. A
repurchase of any shares received upon exercise of the Option will be made at an
aggregate price equal to the Market/Offer Price multiplied by the number of
shares to be repurchased.

    The term "Market/Offer Price" means the highest of the following:

    (1) the price per share at which a tender or exchange offer has been made
       for the Common Stock,

    (2) the price per share of the Common Stock that any third party is to pay
       pursuant to an agreement with the Company,

    (3) the highest closing price per share of the Common Stock within the
       six-month period immediately preceding the date that notice to repurchase
       is given, or

    (4) if there is a sale of all or a substantial portion of the Company's
       assets, the sum of the price paid for those assets and the current market
       value of the remaining assets (as determined by a nationally recognized
       investment banking firm), divided by the number of shares of the Common
       Stock outstanding at the time of such sale.

    The term "Repurchase Event" is defined in the Option Agreement to mean
(1) the acquisition by any third party of beneficial ownership of 50% or more of
the outstanding shares of Common Stock or (2) the consummation of a merger,
consolidation or similar transaction involving the Company or any purchase,
lease or other acquisition of all or a substantial portion of the assets of the
Company unless the transaction would not constitute an Acquisition Transaction,
in either case provided that a Subsequent Triggering Event shall have occurred
prior to an Exercise Termination Event.

    TOTAL PROFIT.  The total profit that Parent may realize with regard to the
exercise of the Option may not exceed $1.5 million. "Total profit" is defined to
mean the aggregate (before taxes) of:

    (1) any amount received by Parent pursuant to the Company's repurchase of
       the Option,

    (2) any amount received by Parent pursuant to the Company's repurchase of
       the Option Shares (less the purchase price for those Option Shares),

    (3) any net cash received pursuant to the sale of Option Shares to any
       unaffiliated party (less Parent's purchase price of those Option Shares),
       and

    (4) any amounts received by Parent on transfer of the Option or any portion
       of the Option to any unaffiliated party.

    STOCKHOLDER AGREEMENTS WITH CERTAIN STOCKHOLDERS OF THE
COMPANY.  Concurrently with the execution of the Merger Agreement, the
directors, certain executive officers, and certain stockholders of the Company,
Mark Bar, Linda Bar, Richard Bard, Philena Enterprises, Yoram Curiel, Martin T.
Hart, Hunt Capital Group, LLC, Richard Lamm, Dorothy Lamm, Heather Lamm, Scott
Lamm, Bruce Raben, and Mark Turnage each entered into a voting agreement with
the Company under which these individuals and entities agreed to:

                                       25
<PAGE>
    (1) vote all of the shares of Common Stock owned, controlled by or
       subsequently acquired by that director or executive officer in favor of
       the Merger, the Merger Agreement and the transactions contemplated by the
       Merger Agreement.

    (2) vote all of the shares of Common Stock owned, controlled by or
       subsequently acquired by that director or executive officer against any
       other Merger Agreement or merger, consolidation, combination, sale of
       substantial assets, reorganization, dissolution, liquidation or winding
       up of the affairs of the Company or the adoption of amendments to the
       Company's charter documents which would frustrate or impede the Merger.

    In addition, with respect to all shares owned of record and all shares
acquired by these directors and executive officers at any time prior to the
effective time of the Merger, each signing stockholder has appointed Parent as
their irrevocable proxy and lawful attorney to vote their shares in favor of the
Merger and the Merger Agreement and against any other Merger or combination
proposal. The stockholder agreements terminate upon the earlier of the
termination of the Merger Agreement or the effective time of the Merger.

    The stockholder agreements also provide that each stockholder will accept
the all cash offer of $7.00 per share made by Parent in accordance with the
Offer and will not withdraw such acceptance, so long as either (1) holders of at
least a majority of the Shares have agreed to accept the cash offer in
accordance with the Offer, or (2) Parent has not terminated the Offer or
permitted the Offer to lapse in accordance with its terms. For purposes of
determining whether the condition in subclause (1) above is satisfied, each
stockholder's shares are to be included in the shares, the holders of which have
accepted the cash offer in accordance with the Offer.

    The stockholder agreements also prohibit each signing stockholder from
soliciting additional acquisition proposals from third parties on behalf of the
Company or from engaging in any discussions with third parties regarding any
acquisition proposal.

    As of November 29, 1999, these directors, executive officers and other
individuals beneficially owned an aggregate of 2,185,406 shares of Common Stock,
which represented approximately 35.2% of the Shares outstanding on that date.

    MERGER NEGOTIATIONS WITH THE COMPANY.  In February 1997, Parent and the
Company commenced initial discussions regarding a possible merger of their
business. The parties terminated these discussions soon thereafter after little
progress was made. Parent and the Company made intermittent contacts with each
other between February 1997 and August 1999, including the execution of a
confidentiality agreement on February 17, 1998, but did not undertake any
further material discussions regarding a potential merger.

    On August 11, 1999, representatives of Parent and the Company met in New
York to discuss a possible merger. At this meeting, the parties also discussed
the Company's planned acquisition of Bridgestone and the Company's source of
financing for the acquisition.

    On August 24, 1999, the representatives of Parent and the Company met a
second time in New York to discuss the terms of a possible merger. Over the next
two weeks representatives of Parent and the Company spoke intermittently via the
telephone to further discuss possible terms of a merger.

    On September 7, 1999, Parent sent a letter to the Company proposing a
merger, subject to further negotiations, definitive documentation and due
diligence.

    On October 4, 1999, Parent sent a follow up letter with further terms of a
potential transaction.

    On October 11, 1999, the Company and Parent executed an additional
confidentiality agreement with Parent.

    On October 13, 1999, representatives of Parent and the Company met in
Denver, Colorado to further discuss the terms of a possible transaction.

                                       26
<PAGE>
    On October 21, 1999, Parent sent a further letter to the Company with terms
of a proposed transaction.

    On October 27, 1999, representatives of Parent and the Company, together
with various financial, legal and accounting advisers, met in London to discuss
the terms of a potential transaction including the form of consideration, the
structure of the transaction and other material items relating to the
transaction.

    On November 11, 1999, Parent and the Company executed a non-binding letter
of intent regarding the proposed transaction. The parties negotiated the
definitive documentation for the Merger over the following two weeks.

    On November 29, 1999, the board of directors of the Company held a meeting
to consider the Offer, the Merger and the Merger Agreement. At the meeting, the
board of directors of the Company heard presentations by its legal counsel with
respect to the terms of the proposed offer, the Merger and the Merger Agreement,
and legal counsel advised the board of directors that the negotiations for the
Merger Agreement were substantially complete.

    At the November 29, 1999 meeting of the board of directors of the Company,
representatives of Wasserstein Perella delivered Wasserstein Perella's oral
opinion that, subject to and based upon the matters described in the opinion, as
of the date of the Merger Agreement, the $7.00 in cash per Share to be paid to
the holders of Shares, pursuant to the Offer and the Merger was fair to such
stockholders from a financial point of view. Wasserstein Perella subsequently
delivered a written opinion, dated the date of the Merger Agreement, to the same
effect.

    On November 30, 1999, Parent, the Purchaser and the Company executed and
delivered the Merger Agreement.

    Based upon such discussion, presentations and opinion, the board of
directors of the Company has unanimously approved the Merger and determined that
the terms of the Offer and the Merger are fair to, and in the best interests of,
the stockholders of the Company and unanimously recommends that stockholders of
the Company accept the Offer and tender their Shares to the Purchaser pursuant
to the terms of the Offer.

12. PURPOSE OF THE OFFER; THE MERGER AGREEMENT

    PURPOSE OF THE OFFER.  The purpose of the Offer is to enable Parent to
acquire control of, and the entire equity interest in, the Company. Following
the consummation of the Offer, the Purchaser and Parent intend to acquire any
remaining equity interest in the Company not acquired in the Offer by
consummating the Merger. The Offer is subject to certain terms and conditions.
Notwithstanding anything to the contrary set forth in this Offer to Purchase,
any determination concerning the satisfaction of such terms and conditions will
be within the reasonable discretion of the Purchaser.

    THE MERGER AGREEMENT.  The Merger Agreement provides that following the
satisfaction or waiver of the conditions described below under "Conditions to
the Merger," the Purchaser will be merged with and into the Company, and each
then outstanding Share (other than Shares (1) owned or held in treasury by the
Company, (2) owned by the Purchaser or Parent, (3) remaining outstanding held by
any subsidiary of the Company or Parent or (4) owned by stockholders, if any,
who are entitled to and who properly exercise dissenters' rights under Colorado
law), will be converted into the right to receive an amount in cash, without
interest, equal to the price per Share paid pursuant to the Offer. Shares
described in (1), (2) and (3) of this paragraph will be cancelled without the
payment of any consideration.

    VOTE REQUIRED TO APPROVE THE MERGER.  The CBCA requires, among other things,
that the adoption of any plan of Merger or consolidation of the Company must be
approved by the board of directors of the Company and, if the "short form"
Merger procedure described below is not available, by the holders of a majority
of the Company's outstanding Shares. The board of directors of the Company has
approved the Offer, the Merger and the Merger Agreement; consequently, the only
additional corporate action of the Company that may be necessary to effect the
Merger is approval by such stockholders if the "short-form"

                                       27
<PAGE>
Merger procedure described below is not available. Under the CBCA, the
affirmative vote of holders of a majority of the outstanding Shares (including
any Shares owned by the Purchaser), is generally required to approve the Merger.
In addition, holders of Company preferred stock will also have the right to vote
on the Merger, on the same basis as the holders of the Shares. If the Purchaser
acquires, through the Offer or otherwise, voting power with respect to at least
a majority of the outstanding Shares (which would be the case if the Minimum
Condition were satisfied and the Purchaser were to accept for payment Shares
tendered pursuant to the Offer), it would have sufficient voting power to effect
the Merger without the vote of any other stockholder of the Company. The CBCA
also provides, however, that if a parent company owns at least 90% of each class
of stock of a subsidiary, the parent company can effect a "short-form" merger
with that subsidiary without the action of the other stockholders of the
subsidiary. Accordingly, if, as a result of the Offer or otherwise, the
Purchaser acquires or controls the voting power of at least 90% of the
outstanding Shares, the Purchaser could (and, under the Merger Agreement, is
required to) effect the Merger using the "short-form" merger procedures without
prior notice to, or any action by, any other stockholder of the Company.

    CONDITIONS TO THE MERGER.  The Merger Agreement provides that the respective
obligations of Parent, the Purchaser and the Company to effect the Merger are
subject to the fulfillment at or prior to the effective time of the Merger of
each of the following conditions: (1) other than as described above with respect
to the "short-form merger procedures" the Offer, the Merger Agreement and the
Merger shall have been approved and adopted by the requisite vote of the
stockholders of the Company in accordance with the CBCA, (2) the Merger
Agreement, the Merger and the Placing and Open Offer shall have been approved
and adopted by the requisite vote of the stockholders of Parent in accordance
with the Listing Rules of London Stock Exchange Limited and (3) no temporary
restraining order, preliminary or permanent injunction, judgment or other order,
decree or ruling nor any statute, rule, regulation or order shall be in effect
which prevents the consummation of the Merger.

    The obligations of Parent and Purchaser to consummate the Merger are also
subject to the satisfaction at or prior to the effective time of the Merger of
the following conditions (unless any such condition is waived in writing by
Parent or the Purchaser):

    (1) the representations and warranties of the Company set forth in the
Merger Agreement shall be true and correct in all material respects (without
giving duplicative effect to any materiality qualification contained in the
applicable representation or warranty) as of the effective time of the Merger
with the same force and effect as though made again at and as of the effective
time of the Merger, except for any representations and warranties that address
matters only as of a particular date (which shall remain true and correct in all
material respects (without giving duplicative effect to any materiality
qualification contained in the applicable representation or warranty) as of such
date) and Parent shall have received a certificate from the Company's chief
executive officer and chief financial officer to that effect;

    (2) the Company shall have performed in all material respects all
obligations required to be performed by the Company under the Merger Agreement
at or prior to the effective time of the Merger and Parent shall have received a
certificate from the Company's chief executive officer and chief financial
officer to that effect;

    (3) there shall not have occurred any change in the business, assets,
prospects, financial condition or results of operations of the Company or any of
its subsidiaries which has had, or is reasonably likely to have, individually or
in the aggregate, a change or effect that is, in the reasonable judgement of
Parent, materially adverse to the business, assets, prospects, financial
condition, results of operations or condition of the Company and its
subsidiaries taken as a whole (a "Material Adverse Effect");

    (4) the Company shall have received all necessary consents or waivers to the
Merger, in form and substance satisfactory to Parent, from the other parties to
each contract, lease or agreement to which the Company is a party, except where
the failure to obtain such consent or waiver would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect;

                                       28
<PAGE>
    (5) the consummation of the Bridgestone Transaction on terms substantially
in accordance with the terms of the Bridgestone Agreement;

    (6) the receipt by Parent of sufficient funds from the Placing and Open
Offer to fund its obligations under the Merger Agreement; and

    (7) the admittance of the New Ordinary Shares to the Official List of the
London Stock Exchange, subject to notice of admittance.

    The obligations of the Company to consummate the Merger are also subject to
the satisfaction at or prior to the effective time of the Merger of the
following conditions (unless any such condition is waived in writing by the
Company):

    (1) the representations and warranties of Parent set forth in the Merger
Agreement shall be true and correct in all material respects (without giving
duplicative effect to any materiality qualification contained in the applicable
representation or warranty) as of the effective date of the Merger with the same
force and effect as though made again at and as of the effective date of the
Merger, except for any representations and warranties that address matters only
as of a particular date (which shall remain true and correct in all material
respects (without giving duplicative effect to any materiality qualification
contained in the applicable representation or warranty) as of such date) and the
Company shall have received a certificate to that effect from Parent's chief
executive officer and chief financial officer and

    (2) Parent shall have performed in all material respects all obligations
required to be performed by it under the Merger Agreement at or prior to the
effective time of the Merger and the Company shall have received a certificate
to that effect from Parent's chief executive officer and chief financial
officer.

    TERMINATION OF THE MERGER AGREEMENT.  The Merger Agreement may be terminated
at any time prior to the effective time of the Merger, whether before or after
approval and adoption of the Merger Agreement by the stockholders of the
Company:

    (1) by mutual agreement of the boards of directors of Parent and the
Company;

    (2) by Parent or the Company if (a) any court of competent jurisdiction in
the United States or other United States governmental body shall have issued an
order, decree or ruling or taken any other action restraining, enjoining or
otherwise prohibiting the Merger and such order, decree or ruling or other
action has become final and nonappealable, (b) there has been a material breach
by the other party of any representation, warranty, covenant or agreement set
forth in the Merger Agreement or the Option Agreement that is not capable of
being cured, (c) the stockholders of Parent shall fail to approve the Merger and
the Placing and Open Offer, or (d) the stockholders of the Company shall fail to
approve the Merger;

    (3) by Parent, if (a) the Company or any of its directors or officers shall

Company described under "No Solicitation by the Company; Acquisition Proposals"
in this Section 12, (b) the board of directors of the Company approves or
recommends an acquisition proposal by a third party (other than Parent) or
withdraws or modifies in a manner adverse to Parent its recommendation that
stockholders of the Company approve the Merger or (c) the Company shall have
failed to mail a proxy statement to the stockholders in connection with the
approval of the Merger by the shareholders of the Company or failed to include
in such proxy statement its recommendation of the Merger Agreement and the
transactions contemplated thereby;

    (4) by Parent prior to the purchase of the Shares pursuant to the Offer, in
the event of a breach or failure to perform by the Company of any
representation, warranty, covenant or other agreement contained in the Merger
Agreement which (a) would give rise to the failure of a condition set forth in
the Stockholder Agreements and (b) cannot be cured, or has not been cured within
15 days after the Company receives written notice from Parent of such breach or
failure to perform;

                                       29
<PAGE>

    (7) by the Company if in response to an acquisition proposal which
constitutes a Superior Proposal (as defined in "No Solicitation by the Company;
Acquisition Proposals" in this Section 12 below) which was not solicited by the

    NO SOLICITATION BY THE COMPANY; ACQUISITION PROPOSALS.  The Merger Agreement
provides that the Company will not, nor will it permit any of it subsidiaries
to, nor will it authorize or permit any of its, directors, officers or employees
or any investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its subsidiaries to, directly or
indirectly, (1) solicit, initiate or encourage (including by way of furnishing
information), or take any other action designed to facilitate, any inquiries or
the making of any proposal which constitutes an Acquisition Proposal (as defined
below) or (2) participate in any discussions or negotiations regarding any
Acquisition Proposal. Notwithstanding the foregoing, if the board of directors
of the Company determines in good faith, after consultation with outside
counsel, that it is necessary to do so in order to comply with its fiduciary
duties to the Company's stockholders under applicable law, the Company, in
response to a Superior Proposal (as defined below) which was not solicited by it
or which did not result from a breach by the Company of its non-solicitation
obligations, and subject to compliance with the Merger Agreement, may furnish
information with respect to the Company and its subsidiaries to any person
making a Superior Proposal pursuant to a confidentiality agreement on terms no
less favorable than the confidentiality agreement between the Company and Parent
and participate in discussions or negotiations regarding such Superior Proposal.

    For purposes of the Merger Agreement, an "Acquisition Proposal" means any
inquiry, proposal or offer from any person (1) relating to any direct or
indirect acquisition or purchase of (a) a business that constitutes 15% or more
of the net revenues, net income or the assets of the Company and its
subsidiaries, taken as a whole, (b) 20% or more of any class of equity
securities of the Company or (c) any material equity interest in any subsidiary
of the Company, (2) relating to any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of the Company or any material equity interest in any
of its subsidiaries, or (3) relating to any merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its subsidiaries, other than the transactions
contemplated by the Merger Agreement.

    For purposes of the Merger Agreement, "Superior Proposal" means any proposal
made by a third party to acquire, directly or indirectly, including pursuant to
a tender offer, exchange offer, merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction, for
consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the Shares then outstanding or all or substantially all
the assets of the Company and otherwise on terms which the board of directors of
the Company determines in its good faith judgment is reasonably likely to be
consummated, taking into account the person making the proposal and all legal,
financial and regulatory aspects of the proposal, and would provide greater
value to the stockholders of the Company than the Merger.

Agreement" in this Section 12.

person making the request and the identity of the person making the Acquisition
Proposal or request for information. The Company must promptly inform Parent of
any change in the status and material terms and conditions (including amendments
or proposed amendments) of any such Acquisition Proposal or request for
information.

(b) cannot be cured, or has not been cured within 15 days after the Company
receives written notice from Parent or Purchaser of such breach or failure to
perform; or

    (7) the Company terminates the Merger Agreement in response to a Superior

    BOARD OF DIRECTORS.  The Merger Agreement provides that promptly upon the
acceptance for payment of, and payment for, Shares by the Purchaser pursuant to
the Offer, the Purchaser will be entitled to designate such number of directors
on the board of directors of the Company as will give the Purchaser, subject to
compliance with Section 14(f) of the Exchange Act, representation on the
Company's board of directors equal to the product of (1) the total number of
directors on the Company's board of directors and (2) the percentage that the
number of Shares purchased by the Purchaser in the Offer bears to the number of
Shares outstanding, and the Company will, at such time, cause the Purchaser's
designees to be selected by its existing board of directors. Subject to
applicable law, the Company has agreed to take all action requested by Parent
necessary to effect any such election, including mailing to its stockholders the
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder. The Merger Agreement
further provides that in the event that the Purchaser's designees are elected to
the board of directors of the Company, until the effective time of the Merger,
the board of directors of the Company will have at least two independent
directors who were directors on the date of the Merger Agreement and who are not
officers of the Company or any of its subsidiaries. The Merger Agreement also
provides that the Company will promptly, at the option of Parent, either
increase the size of the Company's board of directors and/or obtain the
resignation of such number of its current directors as is necessary to enable
the Purchaser's designees to be elected or appointed to, and to constitute a
majority of, the Company's board of directors as provided above.

    STOCK OPTIONS.  The Merger Agreement provides that prior to the effective
time of the Merger, the Company shall to terminate the Company Equity Plans and
shall provide written notice to each holder of a then outstanding option to
purchase shares of Common Stock pursuant to the Company Equity Plans (whether or
not such option is then vested or exercisable), that such option shall be
exercisable in full as of the date of such notice and that such option shall
terminate at the effective time of the Merger and that, if such option is not
exercised or otherwise terminated before the effective time of the Merger, such
holder shall be entitled to receive in cancellation of such option a cash
payment from Parent promptly after the effective time of the Merger, in an
amount equal to the excess, if any, by which the Offer Price exceeds the
exercise price per share with respect to such option multiplied by the number of
shares represented by such option immediately prior to such cancellation,
subject to income tax withholding as required by applicable law.

    WARRANTS.  The Merger Agreement also provides that, prior to the effective
time of the Merger, the Company shall use its commercially reasonable efforts to
receive from each holder of an outstanding warrant to purchase shares of Common
Stock an agreement that, as of the effective time of the Merger, such warrant
shall be converted into a right of such holder to receive from Parent promptly
after the effective time of the Merger an amount in cash, without interest equal
to the product of (1) the number of shares of Common Stock subject to such
warrant immediately prior to the effective time of the Merger and

                                       34
<PAGE>
(2) the excess, if any, by which the Offer Price exceeds the exercise price per
share that was applicable with respect to such warrant.

    DEBENTURES.  The Merger Agreement further provides that, prior to the
effective time of the Merger, the Company shall use its commercially reasonable
efforts to receive from each holder of an outstanding debenture issued by the
Company an agreement that, simultaneously with the consummation of the Merger
and at the effective time of the Merger, the debenture then held by it shall,
automatically and without further action by the holder of the debenture, be
cancelled and deemed to be paid-in-full. Promptly after the effective time of
the Merger. Parent shall pay to each holder of a debenture with a strike price
of $6.00 who shall have entered into an agreement with the Company for the
cancellation of such holder's debenture, an amount in cash equal to 116.67% of
such debenture holders' pro-rata share of the outstanding principal amount of
such class of debenture, together with accrued interest thereon as provided in
the applicable debentures. The maximum aggregate consideration payable to the
holders of debentures with a strike price of $6.00 by Parent, assuming that all
such holders enter into agreements with the Company for the cancellation of
their debentures, shall be $583,350. In addition, promptly after the effective
time of the Merger, Parent shall pay to each holder of a debenture with a strike
price of $6.50 who shall have entered into an agreement with the Company for the
cancellation of such holder's debenture, an amount in cash equal to 109% of such
debenture holders' pro-rata share of the outstanding principal amount of such
class of debenture, together with accrued interest thereon as provided in the
applicable debentures. The maximum aggregate consideration payable to the
holders of debentures with a strike price of $6.50 by Parent, assuming that all
such holders enter into agreements with the Company for the cancellation of
their debentures, shall be $3,019,300. From and after the effective time of the
Merger, none of Parent, Purchaser or the Company shall have any liability or
obligation of any kind whatsoever under debentures with respect to which the
holder shall have received payment as described herein.

    EMPLOYEE MATTERS.  The Merger Agreement provides that from and after the
Merger, Parent will cause the Surviving Corporation to provide, employee benefit
plans, programs and arrangements to employees of the Company which are in the
aggregate at least as favorable as those maintained by the Company today.

    The Merger Agreement also provides that with respect to each benefit plan,
program practice, policy or arrangement maintained by the Surviving Corporation
in which employees of the Company subsequently participate, for purposes of
determining vesting and entitlement to benefits, including for severance
benefits and vacation entitlement (but not for accrual of pension benefits),
service with the Company (or predecessor employers to the extent the Company
provides past service credit) will be treated as service with the Surviving
Corporation.

    As described in the Company's most recent proxy statement dated November 2,
1999, the Company is party to an amended employment agreement with Richard H.
Bard, Chairman and Chief Executive Officer of the Company. Under the terms of
his employment agreement, Mr. Bard is entitled to certain benefits in the event
of an acquisition of the Company. In connection with the execution of the Merger
Agreement, the Company and Mr. Bard entered into an amendment to his employment
agreement.

    Under the amendment executed by the Company and Mr. Bard dated as of
November 30, 1999 (the "Amendment"), Mr. Bard's employment with the Company will
terminate on the later to occur of the effective time of the Merger and January
31, 2000. In addition, the Company has agreed to pay to Mr. Bard bonuses for
past service to the Company for the years 1997, 1998 and 1999 in the amounts of
$160,000, $200,000 and $240,000, respectively. Furthermore, in the Amendment,
Mr. Bard has agreed that the provisions of his employment agreement which
provide for a payment upon termination of 1.5 times the present value of the
salary and other benefits for the remaining term (currently through March 31,
2006) of the agreement are to be deleted.

    In addition to the foregoing, in the Merger Agreement, Parent has agreed to
pay to Mr. Bard following the effective time of the Merger an amount in cash
equal to $3,500,000 in full satisfaction of

                                       35
<PAGE>
certain rights of Mr. Bard under his employment agreement to receive 500,000
shares of Common Stock upon a merger or acquisition of the Company and certain
other rights to which he is entitled under his employment upon a termination of
his employment with the Company. Furthermore, Parent has also agreed in the
Merger Agreement to pay to Mr. Bard $250,000 in full satisfaction of his options
to acquire 147,000 shares of Common Stock.

    After the consummation of the Merger, Mark Turnage, the current President
and Chief Operating Officer of the Company, will (1) assume primary
responsibility for the United States operations of the Surviving Corporation and
be entitled to an annual salary of $200,000, (2) join the board of directors of
Parent and the Surviving Corporation, pending the requisite shareholder
approval, (3) be entitled to participate in a bonus plan, receive certain
pension contributions (to be agreed) and to benefit from a company car and
private medical health insurance cover, and (4) become entitled to receive
payments of bonuses from the Company in respect of prior years' service in the
amount of approximately $390,000, and an additional bonus of approximately
$110,000. Mr. Turnage has agreed to invest such payment in New Ordinary Shares
at their issue price and to retain such shares for a minimum period of one year.

    INDEMNIFICATION.  From and after the consummation of the Merger and for a
period of six years thereafter, Parent will, or will cause the Surviving
Corporation to, fulfill and honor in all respects the obligations of the Company
to indemnify each person who is or was a director or officer (an "Indemnified
Party") of the Company or any of its subsidiaries pursuant to any
indemnification provision of the Company's articles of incorporation or by-laws
as each is in effect on the date of the Merger Agreement. In addition, for a
period of six years after the Merger, the Surviving Corporation will not amend
or reduce the rights to indemnification provided in the articles of
incorporation of the Company. Furthermore, the Merger Agreement provides that,
for a period of three years after the consummation of the Merger, Parent shall
cause to be maintained in effect the current officers' and directors' liability
insurance maintained by the Company with respect to the Indemnified Parties to
the extent that it provides coverage for events occurring prior to the
consummation of the Merger for all persons who are directors and officers of
Seller on the date of the Merger Agreement, so long as such insurance is
available on commercially reasonable terms and the annual premium for such
liability insurance would not be in excess of 200% of the last annual premium
paid prior to the date of the Merger Agreement If the existing officers' and
directors' liability insurance expires, is terminated or cancelled during such
three-year period, Parent will use all reasonable efforts to cause to be
obtained as much officers' and directors' liability insurance as can be obtained
for the remainder of such period for an annualized premium as provided in the
Merger Agreement and on terms and conditions no less advantageous than the
existing officers' and directors' liability insurance.

    COMMERCIALLY REASONABLE EFFORTS.  Upon the terms and subject to the
conditions set forth in the Merger Agreement, Parent, the Purchaser and the
Company have each agreed to use its commercially reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with each other in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Offer, the Merger and the other transactions contemplated by
the Merger Agreement, including (1) the taking of all reasonable acts necessary
to cause the conditions of the Offer to be satisfied, (2) the obtaining of all
necessary actions or nonactions, waivers, consents and approvals from
governmental entities and the making of all necessary registrations and filings
and the taking of all steps as may be necessary to obtain an approval or waiver
from, or to avoid an action or proceeding by, any governmental entity, (3) the
obtaining of all necessary consents, approvals or waivers from third parties,
(4) the defending of any lawsuits or other legal proceedings, whether judicial
or administrative, challenging the Merger Agreement or the consummation of the
transactions contemplated by the Merger Agreement, including seeking to have any
stay or temporary restraining order entered by any court or other governmental
entity vacated or reversed, and (5) the execution and delivery of any additional
instruments necessary to consummate the transactions contemplated by, and to
fully carry out the purposes of, the Merger Agreement. In connection with and
without limiting the foregoing, but subject

                                       36
<PAGE>
to the terms and conditions of the Merger Agreement, the Company and its board
of directors will (1) take all action necessary to ensure that no state takeover
statute or similar statute or regulation is or becomes applicable to the Offer,
the Merger, the Merger Agreement or any of the other transactions contemplated
by the Merger Agreement, and (2) if any state takeover statute or similar
statute or regulation becomes applicable to the Offer, the Merger, the Merger
Agreement or any other transaction contemplated by the Merger Agreement, take
all action necessary to ensure that the Offer, the Merger, the Merger Agreement
and the other transactions contemplated by the Merger Agreement may be
consummated as promptly as practicable on the terms contemplated by the Offer
and the Merger Agreement and otherwise to minimize the effect of such statute or
regulation on the Offer, the Merger, the Merger Agreement and the other
transactions contemplated by the Merger Agreement.

    The Merger Agreement further provides that the Company will give prompt
notice to Parent, and Parent will give prompt notice to the Company, of (1) the
occurrence, or non-occurrence, of any event which would be likely to cause any
representation or warranty contained in the Merger Agreement to be untrue or
inaccurate in any material respect or any covenant, condition or agreement
contained in the Merger Agreement not to be complied with or satisfied or
(2) any failure of the Company, Parent or the Purchaser to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it under the Merger Agreement; provided that no such notification will limit or
otherwise affect the remedies available to the party receiving the notice.

    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties. The foregoing summary of the Merger
Agreement is qualified in its entirety by reference to the Merger Agreement, a
copy of which is filed as Exhibit (c)(1) to the Purchaser's Tender Offer
Statement on Schedule 14D-1 filed with the Commission on the date hereof (the
"Schedule 14D-1") and incorporated by reference herein. The Merger Agreement
should be read in its entirety for a more complete description of the matters
summarized above.

    APPRAISAL RIGHTS.  No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated holders of Shares will have certain
rights pursuant to the provisions of Section 7-113-102 of the CBCA to dissent
and demand appraisal of, and to receive payment in cash of the fair value of,
their Shares. If the statutory procedures were complied with, such rights could
lead to a judicial determination of the fair value required to be paid in cash
to such dissenting holders for their Shares. In determining the fair value of
the Shares, the court is required to take into account all relevant factors.
Accordingly, any such judicial determination of the fair value of Shares could
be based upon considerations other than or in addition to the Offer Price or the
market value of the Shares, including the asset value and investment value of
the Shares. The value so determined could be more or less than the Offer Price
or the Merger Consideration.

    If any holder of Shares who demands appraisal under Section 7-113-102 of the
CBCA fails to perfect, or effectively withdraws or loses his right to appraisal,
as provided in the CBCA, the Shares of such stockholder will be converted into
the Merger Consideration in accordance with the Merger Agreement.

    The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the CBCA and is qualified in its entirety by the full
text of Section 7-113-102 of the CBCA.

    FAILURE TO FOLLOW THE STEPS REQUIRED BY THE CBCA FOR PERFECTING APPRAISAL
RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

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

13. DIVIDENDS AND DISTRIBUTIONS

    Pursuant to the terms of the Merger Agreement, prior to the effective time
of the merger, unless otherwise permitted in the Merger Agreement or approved in
writing by the Purchaser, the Company may not (1) declare, set aside, make or
pay any dividends on, or make any other 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 securities convertible into or exchangeable for any
such shares. Nothing herein shall constitute a waiver by the Purchaser or Parent
of any of its rights under the Merger Agreement or a limitation of remedies
available to the Purchaser or Parent for any breach of the Merger Agreement,
including termination thereof.

14. CERTAIN CONDITIONS OF THE OFFER

    Notwithstanding any other term of the Offer or the Merger Agreement, the
Purchaser will not be required to accept for payment or, subject to any
applicable rules and regulations of the Commission, including Rule 14e-1(c)
under the Exchange Act (relating to the Purchaser's obligation to pay for or
return tendered Shares after the termination or withdrawal of the Offer), to pay
for any Shares tendered pursuant to the Offer unless the Minimum Condition shall
have been satisfied. Furthermore, the Purchaser will not be required to accept
for payment or, subject as aforesaid, to pay for any Shares not theretofore
accepted for payment or paid for, and may, in accordance with the provisions of
the Merger Agreement described in the subsection entitled "Termination of the
Merger Agreement" in Section 12 above, terminate the Merger Agreement or amend
the Offer with the consent of the Company, if, upon the scheduled expiration
date of the Offer (as extended, if required, pursuant to the provisions
discussed in Section 1 above), any of the following conditions exists and is
continuing and does not result principally from the breach by Parent or the
Purchaser of any of their obligations under the Merger Agreement:

    (1) there shall be instituted or pending by any governmental entity any
suit, action or proceeding (a) challenging the acquisition by Parent or the
Purchaser of any Shares under the Offer, seeking to restrain or prohibit the
making or consummation of the Offer or the Merger or the performance of any of
the other transactions contemplated by the Merger Agreement or seeking to obtain
from the Company, Parent or the Purchaser any damages that are material in
relation to the Company and its subsidiaries as a whole, (b) seeking to prohibit
or materially limit the ownership or operation by the Company, Parent or any of
Parent's subsidiaries of all or a portion of the business or assets of the
Company or Parent and its subsidiaries, taken as a whole, or to compel the
Company or Parent and its subsidiaries to dispose of or hold separate all or a
portion of the business or assets of the Company or Parent and their
subsidiaries, taken as a whole, in each case as a direct result of the Offer or
any of the other transactions contemplated by the Merger Agreement, (c) seeking
to impose material limitations on the ability of Parent or the Purchaser to
acquire or hold, or exercise full rights of ownership of, any Shares to be
accepted for payment pursuant to the Offer, including, without limitation, the
right to vote such Shares on all matters properly presented to the stockholders
of the Company, (d) seeking to prohibit Parent or any of its subsidiaries from
effectively controlling in any material respect any material portion of the
business or operations of the Company, (e) that could reasonably be expected to
require the divestiture by Parent or the Purchaser of Shares, in the case of any
of the foregoing in clauses (b), (c) or (d), which could reasonably be expected,
individually or in the aggregate, to have a material adverse effect on the
businesses of the Company and its subsidiaries, or (f) that could reasonably be
expected to result in a material adverse effect on the Company or Parent;

    (2) there shall be any statute, rule, regulation, judgment, order or
injunction enacted, entered, enforced, promulgated or deemed applicable to the
Offer or the Merger, by any governmental entity or court that would result in
any of the consequences referred to in clauses (a) through (f) of paragraph (1)
above;

                                       38
<PAGE>
    (3) there shall have occurred any events or changes which have had or which
could reasonably be expected to have, individually or in the aggregate, a
material adverse effect on the Company;

    (4) any of the representations and warranties of the Company set forth in
the Merger Agreement that are qualified as to materiality shall not be true and
correct or any such representations and warranties that are not so qualified
shall not be true and correct in any material respect, in each case, at the date
of the Merger Agreement and at the scheduled or extended expiration of the
Offer;

    (5) the Company shall have failed to perform in any material respect any
material obligation or to comply in any material respect with any material
agreement or material covenant of the Company to be performed or complied with
by it under the Merger Agreement, which failure to perform or comply cannot be
cured, or has not been cured within 15 business days after the Company receives
written notice from Parent of such breach or failure to perform;

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

    (7) any consent (other than the filing of the Certificate of Merger or
Company Stockholder Approval if required by the CBCA) required to be filed, or
to have occurred or been obtained by the Company or any of its Subsidiaries in
connection with the execution and delivery of the Merger Agreement, the Offer
and the consummation of the transactions contemplated by the Merger Agreement
shall not have been filed or obtained or shall not have occurred, except where
the failure to obtain such consent could not reasonably be expected to have,
individually or in the aggregate, a material adverse effect on the Company;

    (8) the Company's board of directors (a) shall have withdrawn, or modified
or changed in a manner adverse to Parent or the Purchaser (including by
amendment of the Schedule 14D-9) its recommendation of the Offer, the Merger
Agreement or the Merger, (b) shall have recommended a Superior Proposal,
(c) shall have adopted any resolution to effect any of the foregoing or
(d) upon request of Parent or the Purchaser, shall fail to reaffirm its approval
of recommendation of the Offer, the Merger Agreement or the Merger;

    (9) the Company shall not have consummated the Bridgestone Transaction on
terms substantially in accordance with the Bridgestone Agreement; or

    (10) any person or "group" (within the meaning of Section 13(d)(3) of the
Exchange Act), other than Parent, the Purchaser or their affiliates or any group
of which any of them is a member, shall have acquired or announced its intention
to acquire beneficial ownership (as determined pursuant to Rule 13d-3
promulgated under the Exchange Act) of 30% or more of the Shares;

and, in the good faith judgment of Parent or the Purchaser, in its sole
discretion, make it inadvisable to proceed with such acceptance of Shares for
payment or the payment therefor.

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

15. CERTAIN LEGAL MATTERS

    Based on a review of publicly available filings made by the Company with the
Commission and other publicly available information concerning the Company and
representations made by representatives of the Company and the Company, neither
the 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 the Purchaser's
acquisition of Shares as contemplated herein or of any

                                       39
<PAGE>
approval or other action, except as otherwise described in this Section 15, by
any governmental entity that would be required for the acquisition or ownership
of Shares by the Purchaser as contemplated herein. Should any such approval or
other action be required, the Purchaser and Parent currently contemplate that
such approval or other action will be sought. Except as otherwise expressly
described in this Section 15, while the Purchaser does not presently intend to
delay the acceptance for payment of or payment for Shares tendered pursuant to
the Offer pending the outcome of any such matter, there can be no assurance that
any such approval or other action, if needed, would be obtained or would be
obtained without substantial conditions or that failure to obtain any such
approval or other action might not result in consequences adverse to the
Company's business or that certain parts of the Company's business might not
have to be disposed of if such approvals were not obtained or such other actions
were not taken or in order to obtain any such approval or other action. If
certain types of adverse action are taken with respect to the matters discussed
below, the Purchaser could decline to accept for payment or pay for any Shares
tendered. See Section 14 for certain conditions to the Offer.

    ANTITRUST.  Under the provisions of the Hart-Scott Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), and the regulations
thereunder applicable to the Offer, an acquiring person and the person whose
voting securities are being acquired in a tender offer must make an HSR filing
by filing a Notification and Report Form with respect to the tender offer if
each of the following three conditions are satisfied: (1) the acquiring person
or the person whose voting securities are being acquired are engaged in commerce
or in any activity affecting commerce, (2)(a) any voting securities or assets of
a person engaged in manufacturing which has annual net sales or total assets of
$10,000,000 or more are being acquired by any person which has total assets or
annual net sales of $100,000,000 or more, (b) any voting securities or assets of
a person not engaged in manufacturing which has total assets of $10,000,000 or
more are being acquired by any person which has total assets or annual net sales
of $100,000,000 or more or (c) any voting securities or assets of a person with
annual net sales or total assets of $100,000,000 or more are being acquired by
any person which has total assets or annual net sales of $10,000,000 or more,
and (3) as a result of such acquisition, the acquiring person would hold
(a) 15% or more of the voting securities or assets of the acquired person, or
(b) an aggregate total amount of the voting securities and assets of the
acquired person in excess of $15,000,000.

    Although Parent, the Purchaser and the Company are engaged in commerce in
satisfaction of the first statutory condition to an HSR filing stated above, and
the consummation of the Offer will result in the acquisition by the Purchaser of
15% or more of the voting securities or assets of the Company in satisfaction of
the third statutory condition to an HSR filing stated above, none of Parent, the
Purchaser and the Company have total assets or annual net sales of $100,000,000
or more in satisfaction of the second statutory condition to an HSR filing.
Therefore, none of Parent, the Purchaser, or the Company is required to file a
Notification and Report Form with respect to the Offer under the HSR Act and
applicable regulations.

    Nevertheless, the FTC and the Antitrust Division may scrutinize the legality
of transactions such as the Purchaser's proposed acquisition of the Company
under the antitrust laws. If the Antitrust Division or the FTC raises
substantive issues in connection with a proposed transaction, the parties may
engage in negotiations with the relevant governmental agency concerning possible
means of addressing those issues and may agree to delay consummation of the
transaction while such negotiations continue. At any time before or after the
Purchaser's purchase of Shares pursuant to the Offer, the Antitrust Division or
FTC could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or the consummation of the Merger or seeking the
divestiture of Shares acquired by the Purchaser or the divestiture of
substantial assets of Parent or its subsidiaries, or the Company or its
subsidiaries. Private parties may also bring legal action under the antitrust
laws under certain circumstances. There can be no assurance that a challenge to
the Offer on antitrust grounds will not be made or, if such a challenge is made,
of the results thereof.

                                       40
<PAGE>
    OTHER FOREIGN APPROVALS.  The Company conducts business in a number of
foreign countries and jurisdictions. In connection with the acquisition of
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 tot he
offer. There can be no assurance that the 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.

16. FEES AND EXPENSES

    The Purchaser has retained MacKenzie Partners, Inc. to act as the
Information Agent and Wilmington 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
under the Federal securities laws.

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

17. MISCELLANEOUS

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. Neither the Purchaser nor Parent is aware of any jurisdiction in
which the making of the Offer or the tender of Shares in connection therewith
would not be in compliance with the laws of such jurisdiction. To the extent the
Purchaser or Parent becomes aware of any state law that would limit the class of
offerees in the Offer, the Purchaser 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.

    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF THE 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.

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

Ladies and Gentlemen:

    The undersigned hereby tenders to Applied Opsec Corporation, a Colorado
corporation (the "Purchaser"), which is a wholly owned subsidiary of Applied
Holographics PLC, a public limited company incorporated and existing under the
laws of England and Wales ("Parent"), the above-described shares of Common
Stock, par value $.005 per share (the "Shares"), of Optical Security
Group, Inc., a Colorado corporation (the "Company"), upon the terms and subject
to the conditions set forth in the Purchaser's Offer to Purchase dated December
3, 1999 (the "Offer to Purchase"), and this Letter of Transmittal (which,
together with any amendments or supplements thereto or hereto, collectively
constitute the "Offer"), receipt of which is hereby acknowledged.

    Upon the terms of the Offer, subject to, and effective upon, acceptance for
payment of, and payment for, the Shares tendered herewith in accordance with the
terms of the Offer, the undersigned hereby sells, assigns and transfers to, or
upon the order of, the Purchaser all right, title and interest in and to all the
Shares that are being tendered hereby (and any and all other Shares or other
securities or rights issued or issuable in respect thereof on or after
November 30, 1999), and irrevocably constitutes and appoints Wilmington Trust
Company (the "Depositary"), the true and lawful agent and attorney-in-fact of
the undersigned, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to the full extent
of the undersigned's rights with respect to such Shares (and any such other
Shares or securities or rights), (1) to deliver certificates for such Shares
(and any such other Shares or securities or rights) or transfer ownership of
such Shares (and any such other Shares or securities or rights) on the account
books maintained by the Book-Entry Transfer Facility together, in any such case,
with all accompanying evidences of transfer and authenticity to, or upon the
order of, the Purchaser, (2) to present such Shares (and any such other Shares
or securities or rights) for transfer on the Company's books and (3) to receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any such other Shares or securities or rights), all in accordance
with the terms of the Offer.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the tendered Shares
(and any and all other shares or other securities or rights issued or issuable
in respect of such Shares on or after November 30, 1999) and, when the same are
accepted for payment by the Purchaser, the Purchaser will acquire good title
thereto, free and clear of all liens, restrictions, claims and encumbrances, and
the same will not be subject to any adverse claim. The undersigned, upon
request, will execute any additional documents deemed by the Depositary or the
Purchaser to be necessary or desirable to complete the sale, assignment and
transfer of the tendered Shares (and any and all such other Shares or securities
or rights).

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

    The undersigned hereby irrevocably appoints David J. Tidmarsh and Michael W.
Angus, and each of them acting singly, and any other designees of the Purchaser,
the attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to vote at any annual, special or adjourned meeting of the
Company's stockholders or otherwise in such manner as each such attorney-in-fact
and proxy or his substitute shall in his or her sole discretion deem proper with
respect to, to execute any written consent concerning any matter as each such
attorney-in-fact and proxy or his or her substitute shall in his or her sole
discretion deem proper with respect to, and to otherwise act as each such
attorney-in-fact and proxy or his or her substitute shall in his or her sole
discretion deem proper with respect to, the Shares tendered hereby that have
been accepted for payment by the Purchaser prior to the time any such action is
taken and with respect to which the undersigned is entitled to vote (and any and
all other Shares or other securities or rights issued or issuable in respect of
such Shares on or after November 30, 1999). This appointment is effective when,
and only to the extent that, the Purchaser accepts for payment such Shares as
provided in the Offer to Purchase. This power of attorney and proxy are
irrevocable and are granted in consideration of the acceptance for payment of
such Shares in accordance with the terms of the Offer. Upon such acceptance for
payment, all prior powers of attorney, proxies and consents given by the
undersigned with respect to such Shares (and any such other Shares or securities
or rights) will, without further action, be revoked and no subsequent powers of
attorney, proxies, consents or revocations may be given (and, if given, will not
be deemed effective) by the undersigned.

    The undersigned understands that the valid tender 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 the Purchaser upon the terms and subject to the conditions of the Offer.

                                  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 (1) if this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this Section, includes any
participant in the Book-Entry Transfer Facility's system whose name appears on a
security position listing as the owner of the Shares) of Shares tendered
herewith, unless such registered holder(s) has completed either the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on this Letter of Transmittal or (2) if such Shares are tendered
for the account of a financial institution (including most commercial banks,
savings and loan associations and brokerage houses) that is a participant in the
Security Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program
(such participant, an "Eligible Institution"). In all other cases, all
signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 5.

    2. REQUIREMENTS OF TENDER.  This Letter of Transmittal is to be completed by
stockholders either if certificates are to be forwarded herewith or, unless an
Agent's Message (as defined below) is utilized, if delivery of Shares is to be
made pursuant to the procedures for book-entry transfer set forth in Section 2
of the Offer to Purchase. For a stockholder to validly tender Shares pursuant to
the Offer, either (1) a Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, together with any required signature guarantees,
or, in the case of a book-entry transfer, an Agent's Message, and any other
required documents, must be received by the Depositary at one of its addresses
set forth herein prior to the Expiration Date and either certificates for
tendered Shares must be received by the Depositary at one of such addresses or
such Shares must be delivered pursuant to the procedures for book-entry transfer
set forth herein (and a Book-Entry Confirmation received by the Depositary), in
each case prior to the Expiration Date, or (2) the tendering stockholder must
comply with the guaranteed delivery procedures set forth below and in Section 2
of the Offer to Purchase.

    If a stockholder desires to tender Shares pursuant to the Offer and such
stockholder's certificates for Shares are not immediately available or the
procedures for book-entry transfer cannot be completed on a timely basis or time
will not permit all required documents to reach the Depositary prior to the
Expiration Date, such stockholder's tender may be effected by properly
completing and duly executing the Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth in Section 2 of the Offer to Purchase.
Pursuant to such procedures, (1) such tender must be made by or through an
Eligible Institution, (2) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form provided by the Purchaser, must
be received by the Depositary prior to the Expiration Date and (3) the
certificates for all tendered Shares in proper form for transfer (or a
Book-Entry Confirmation with respect to all such Shares), together with a Letter
of Transmittal (or facsimile thereof), properly completed and duly executed,
with any required signature guarantees, or, in the case of a book-entry
transfer, an Agent's Message, and any other required documents, must be received
by the Depositary within three trading days after the date of execution of such
Notice of Guaranteed Delivery as provided in Section 2 of the Offer to Purchase.
A "trading day" is any day on which the New York Stock Exchange, Inc. is open
for business.

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

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

    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 facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.

    3. INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
schedule attached hereto.
<PAGE>
    4. PARTIAL TENDERS.  (Applicable to Certificate Stockholders Only). If fewer
than all the Shares evidenced by any certificate submitted are to be tendered,
fill in the number of Shares that are to be tendered in the box entitled "Number
of Shares Tendered." In any such case, new certificate(s) for the remainder of
the Shares that were evidenced by the old certificate(s) will be sent to the
registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the acceptance for payment
of, and payment for, the Shares tendered herewith. All Shares represented by
certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.

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

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

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

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

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

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

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

    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

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

    8. WAIVER OF CONDITIONS.  The Purchaser reserves the absolute right to waive
any of the specified conditions of the Offer, in whole or in part at any time
and from time to time in its sole discretion.

    9. BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  In order to avoid backup
withholding of Federal income tax on payments of cash pursuant to the Offer, a
stockholder surrendering Shares in the Offer must, unless an exemption applies,
provide the Depositary with such stockholder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 below in this Letter of Transmittal and
certify under penalty of perjury that such TIN is correct and that such
stockholder is not subject to backup withholding. If a stockholder does not
provide such stockholder's correct TIN or fails to provide the certifications
described above, the Internal Revenue Service (the "IRS") may impose a penalty
on such stockholder and the payment of cash to such stockholder pursuant to the
Offer may be subject to backup withholding of 31%.
<PAGE>
    Backup withholding is not an additional income tax. Rather, the amount of
the backup withholding can be credited against the U.S. federal income tax
liability of the person subject to the backup withholding, provided that the

                           IMPORTANT TAX INFORMATION

    Under Federal income tax law, a stockholder is required to provide the
Depositary such stockholder's TIN (i.e., social security number or employer
identification number) on Substitute Form W-9 (or otherwise establish a basis
for exemption from backup withholding) and certify under penalty of perjury that
such TIN is correct and that such stockholder is not subject to backup
withholding. If the Shares are held in more than one name or are not in the name
of the actual owner, consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which number to report. If the Depositary is not provided with a
stockholder's correct TIN, the stockholder or other payee may be subject to a
penalty imposed by the Internal Revenue Service. In addition, any amounts
payable to such stockholder in connection with the Offer may be subject to
backup withholding at a 31% rate.

    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% on all payments made prior to the time a properly certified TIN is
provided to the Depositary.

    Foreign stockholders should complete and sign the main signature form and a
Form W-8, Certificate of Foreign Status, a copy of which may be obtained from
the Depositary, in order to avoid backup withholding. See the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for more instructions.

                                             (1) The number shown on this form is my correct taxpayer identification
                                             number (or I am waiting for a number to be issued to me) and
                                             (2) I am not subject to backup withholding because (a) I am exempt from
                                             backup withholding, or (b) I have not been notified by the Internal Revenue
                                                 Service ("IRS") that I am subject to backup withholding as a result of a
                                                 failure to report all interest or dividends, or (c) the IRS has notified
                                                 me that I am no longer subject to backup withholding.

                                             CERTIFICATION INSTRUCTIONS You must cross out item (2) in Part 2 above if

                                             because you have failed to report all interest or dividends on your tax
                                             returns. However, if after being notified by the IRS that you were subject
                                             to backup withholding you received another notification from the IRS stating
                                             that you are no longer subject to backup withholding, do not cross out such
                                             item (2). If you are exempt from backup withholding, check the box in Part 4

a taxpayer identification number to a payer. Certain penalties may also apply.

PENALTIES

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

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
    include any portion of an includible payment for interest, dividends, or
    patronage dividends in gross income, such failure will be treated as being
    due to negligence and will be subject to a penalty of 20% on any portion of
    an underpayment attributable to that failure unless there is clear and
    convincing evidence to the contrary.

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

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

SERVICE.

         Applied Opsec Corporation, a Colorado corporation (the "Purchaser") and
a wholly owned subsidiary of Applied Holographics PLC, a public limited company
incorporated and existing under the laws of England and Wales ("Parent"), is

and subject to the conditions set forth in the Offer to Purchase, dated December

Shares (determined as of the date of the expiration of the Offer on a fully
diluted basis for all outstanding stock options, warrants and any other
rights to acquire Shares outstanding on the date of the expiration of the
Offer, as further described in the Offer) (the "Minimum Condition").

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of November 30, 1999 (the "Merger Agreement"), among Parent, the
Purchaser and the Company pursuant to which, following the consummation of the

owned by the Company or any subsidiary of the Company or by Parent, the
Purchaser or any other subsidiary of Parent or by stockholders, if any, who are
entitled to and who properly exercise appraisal rights under Colorado law) will

or written notice to the Depositary of the Purchaser's acceptance for payment
of such Shares. Upon the terms and subject to the conditions of the Offer,
payment for Shares purchased pursuant to the Offer will be made by deposit of
the purchase price therefor with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the
Purchaser and transmitting payment 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 timely confirmation of
book-entry transfer of such Shares into the Depositary's account at the
Book-Entry Transfer Facility (as defined in the Offer to Purchase) pursuant
to the procedures set forth in Section 2 of the Offer to Purchase, (ii) a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof) with any required signature guarantees, or, in the case of a
book-entry transfer, an Agent's Message (as defined in the Offer to Purchase)
and (iii) any other documents required by the Letter of Transmittal. Under no
circumstances will interest be paid by the Purchaser on the purchase price of
the Shares to be paid by the Purchaser, regardless of any extension of the
Offer or any delay in making such payment.

         The term "Expiration Date" means 12:00 noon, New York City time, on
Friday, January 7, 2000, unless and until the Purchaser, in its sole
discretion but subject to the terms of the Merger Agreement, shall have
extended the period of time during which the Offer is open, in which event
the term "Expiration Date" shall mean the latest time and date on which the
Offer, as so extended by the Purchaser, shall expire. The Purchaser expressly
reserves the right, in its sole discretion, at any time or from time to time,
and regardless of whether or not any of the events set forth in Section 14 of
the Offer to Purchase shall have occurred, (i) to extend the period of time
during which the Offer is open and thereby delay acceptance for payment of,
and the payment for, any Shares, by giving oral or written notice of such
extension to the Depositary and (ii) to amend the Offer in any other respect
by giving oral or written notice of such amendment to the Depositary. The
Purchaser shall not have any obligation to pay interest on the purchase price
for tendered Shares, whether or not the Purchaser exercises its right to
extend the Offer. There can be no assurance that the Purchaser will exercise
its right to extend the Offer. Any such extension will be followed by a
public announcement thereof no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date. During
any such extension, all Shares previously tendered and not withdrawn will
remain subject to the Offer, subject to the right of a tendering stockholder
to withdraw such stockholder's Shares.

         Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn at any time prior to the
Expiration Date and, unless previously accepted for payment and paid for by the
Purchaser pursuant to the Offer, may also be withdrawn at any time after
February 3, 1999. For a withdrawal to be effective, a written or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of the Offer to Purchase and
must specify the name of the person having delivered the Shares to be withdrawn,
the number of Shares to be withdrawn and the name of the registered holder of
the Shares to be withdrawn, if different from the name of the person who
tendered the Shares. If certificates for Shares have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been tendered by an Eligible
Institution (as defined in Section 2 of the Offer to Purchase), the signatures
on the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been tendered pursuant to the procedures for book-entry transfer as
set forth in Section 2 of the Offer to Purchase, any notice of withdrawal must
also specify the name and number of the account at the Book-Entry Transfer
Facility to be credited with the withdrawn shares and otherwise comply with the
Book-Entry Transfer Facility's procedures. Withdrawals of tenders of Shares may
not be rescinded, and any Shares properly withdrawn will thereafter be deemed
not validly tendered for purposes of the Offer. However, withdrawn Shares may be
re tendered by again following one of the procedures described in Section 2


<PAGE>

of the Offer to Purchase at any time prior to the Expiration Date. All questions
as to the form and validity (including time of receipt) of notices of withdrawal
will be determined by the Purchaser, in its sole discretion, whose determination
will be final and binding.

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

the Securities Exchange Act of 1934 is contained in the Offer to Purchase and is

INTRODUCTION

It is announced today that Applied Holographics has entered into an agreement to
acquire OpSec for approximately US$64 million in cash (L39.93 million). OpSec is
listed on the Nasdaq securities exchange and is a leading provider in the US of
security and product authentication solutions.

By a separate loan agreement entered into between Applied Holographics and
OpSec, Applied Holographics has agreed to lend OpSec US$10 million (L6.24
million), financed by a short term bank facility, to enable OpSec to complete
its acquisition of Bridgestone. Bridgestone also provides security
authentication products and services.

The Board also announced today a Placing and Open Offer to raise approximately
L52.5 million (net of expenses) to fund the consideration payable in connection
with the OpSec Acquisition, to re-finance the OpSec Loan and to provide working
capital for the Enlarged Group. 10,132,240 New Ordinary Shares have been placed
firm with institutional and other investors and 10,238,130 New Ordinary Shares
have been placed subject to recall to satisfy valid applications by Qualifying
Shareholders under the Open Offer. The Open Offer is being made on the basis of
5 New Ordinary Shares for every 13 existing Ordinary Shares held at the close of
business on the Record Date. The Placing and Open Offer is fully underwritten by
Greig Middleton & Co Limited.

Contemporaneously with the Placing and Open Offer, the Company also proposes to
issue 3,100,000 New Ordinary Shares at the issue price to trustees of new
employee share schemes of the Company. Mark Turnage, President and Chief
Executive of OpSec, who will become Deputy Chief Executive of the Enlarged
Group, will also subscribe for up to 115,000 shares at the issue price.

The OpSec Acquisition will be effected by means of a US Tender Offer and Merger.
The Tender Offer has been unanimously recommended to the shareholders of OpSec
by its directors, and is conditional, INTER ALIA, upon the acceptance of the
holders of a majority of the OpSec Shares on a fully diluted basis. Certain
OpSec shareholders, including all of its directors and some members of its
senior management team, together holding approximately 34 percent. of the
existing issued OpSec Shares, have agreed irrevocably to tender their Opsec
Shares pursuant to the Tender Offer.

As part of the Proposals, the Directors propose that the name of the Company is
changed to Applied Optical Technologies plc.

In addition, Applied Holographics announced today its interim results for the
six months ended 30 September 1999.


INFORMATION ON OPSEC AND BRIDGESTONE

OPSEC
OpSec designs, manufactures and supplies imaging-based foils, labels, laminates
and technology and optical coatings for a range of security, document
authentication, product protection and anti-tampering applications.

OpSec operates in five key areas:

- -    BRAND PROTECTION - protection of branded and licensed products against
     counterfeiting and diversion
- -    DOCUMENT AUTHENTICATION - travellers cheques, credit cards, gift
     certificates and event tickets
- -    GOVERNMENT PRODUCTS - security features for passports, driving licences,
     identification cards and other government-issued documents
- -    PHARMACEUTICALS AND AGROCHEMICALS - authentication and tamper-evident
     labels
- -    PARTS AUTHENTICATION AND TRACKING - protection, authentication and tracking
     of automotive, aircraft and other components

OpSec's products offer a range of overt and covert security technologies which
protect documents and products from forgery and counterfeiting, deter tampering,
provide authentication and track and prevent diversion. OpSec's technologies can
be used with a variety of marking systems, including labels, hang tags, hot
stamping foils, laminates, plastic pouches and threads.

OpSec's customers include US federal, state and overseas governments as well as
major companies and organisations. OpSec has production facilities on the East
Coast of the US and design and origination premises in Loughborough in the UK.

BRIDGESTONE
Bridgestone is also involved in providing security authentication products and
services for anti-counterfeiting and anti-diversion purposes to corporate and
government customers. Its products and services include embossed security
labels, data tracking and compliance and monitoring.

It is proposed that Bridgestone's printed and polymer labels operations will be
transferred after completion of the Bridgestone Acquisition to Keystone Imaging
Technology LLC, a company in which OpSec will retain a 19.9 per cent interest.
Bridgestone's continuing operations will be transferred to OpSec's existing
production facilities over a period of twelve months from completion of the
Bridgestone Acquisition.

BACKGROUND TO AND REASONS FOR THE ACQUISITION

Applied Holographics' strategy over the past few years has been to achieve
growth and improved profitability by focusing on specific products directed to
selected markets. The Directors believe that the Company now has established
market positions in the key product areas of security and selected packaging
applications.


<PAGE>


The Directors believe that the OpSec Acquisition will provide Applied
Holographics with the opportunity significantly to enhance its position in the
security market by combining the Company's existing expertise in currency and
document protection with OpSec's expertise in document and brand protection.
OpSec has a complementary product range and customer base, a strong sales and
marketing team, technical capability and experienced management.

The Enlarged Group will maintain production facilities in both the UK and the US
which the Directors believe will enable it to service its clients' increasing
focus on global sales. Applied Holographics will retain its packaging capability
where, increasingly, it will place an emphasis on branding and brand protection,
where the security benefits of the use of holography and related technologies
are increasingly being recognised by its customers. An immediate benefit of the
Acquisition will be the ability of OpSec and Applied Holographics to source from
each other products and technologies not currently in their respective
portfolios. This will provide enhanced marketing opportunities for both
companies.

DIRECTORS AND SENIOR MANAGEMENT OF THE ENLARGED GROUP

Mark Turnage, currently president and chief operating officer of OpSec, will
assume primary responsibility for the Enlarged Group's operations in the
Americas. He will join the Board upon completion of the Acquisition in the role
of Deputy Chief Executive. Richard Bard, currently chairman and chief executive
of OpSec, will stand down from his executive responsibilities within OpSec upon
completion of the Acquisition.

FINANCIAL EFFECTS OF THE ACQUISITION

The Acquisition is expected to enhance earnings per share (before goodwill
amortisation) for the year ending 31 March 2001.

CFC

The Company currently licenses technology to CFC for use by it in generating
holography sales in the US, Canada and Mexico. In return, the Company receives a
six per cent. royalty on all such sales. During the six months to 30 September
1999, the total royalties receivable by the Company from CFC under these
arrangements amounted to approximately US$213,000. As a consequence of the
Acquisition, the Company has agreed with CFC to terminate the existing
arrangements in return for a one-off severance payment by CFC to the Company of
approximately US$3.5 million. The existing joint venture between the Company and
Nimbus CD International Inc. in the US relating to the licensing of
anti-counterfeiting technologies for compact discs will not be affected by the
Acquisition.

CURRENT TRADING AND PROSPECTS FOR THE ENLARGED GROUP

Applied Holographics trading remains in line with expectations and, accordingly,
the Directors are confident in the outlook for the Enlarged Group for the
current financial year of the Company.


<PAGE>


THE PLACING

INTERIM RESULTS FOR THE SIX MONTHS ENDED 30 SEPTEMBER 1999

CHAIRMAN'S STATEMENT
I am pleased to report that in the six months to 30 September 1999 profits rose
to L1,193,723 (1998: L966,256) on Group turnover of L7,481,515 (1998:
L7,224,337). The Group operating profit was L112,307 (1998: L636,970). The
contribution from joint ventures and associated undertakings was L1,193,406
(1998: L383,808).

In my Chairman's statement contained within the last Annual Report, I cautioned
that the disruption caused by the installation of the facilities required to
enable the production facility at Crowther to undertake bank note and high
security work would inevitably impact production in the early months of the
current year. This was the case and the first three months of the period
suffered from a fall in volumes coupled with a high level of rejects. As a
result, there was a loss for the first quarter but this was fully offset by
profits in the subsequent three months as the upgraded plant became fully
operational.

A major contribution to profits in the first six months resulted from the
machine element of a new Microsoft contract. It should be noted that whilst the
contribution via our share in the 3DCD joint venture contract is largely
accounted for in the first half year, the Group will receive a significant
benefit in the second half from the associated contract to supply security
products to the production units.

Our production facility now has full ECB approval and initial orders for Euro
note production have been secured. Unsurprisingly, given the complexity of
introducing the Euro, there has been some slippage in the overall programme with
some consequent delay in the placing of orders for holographic patches and
stripes. We have been pleased with the reception which our products have
received and remain confident that we will win significant business with a
number of bank note printers and paper manufacturers.

Our banknote and high security activities are not solely directed at the Euro
programme and during the period we received orders for holographic thread
material and patches for use in a number of currency applications by countries
outside the EU. This continues to be an expanding market and with our enhanced
facilities we are well placed to benefit from the growth in this market.

The use of holography for document and brand protection continues to expand into
new areas. The largest of the general security contracts won in the period was a
three year contract with a major European railway operation for a national
transport scheme. Initial production for this order will start in the second
half of the current year.

The unaudited consolidated cash flow statement reflects the impact of debtor
levels arising from the higher sales in August and September coupled with a
continuing high level of capital expenditure without the benefit of a
distribution from 3DCD which will be received in the second half.

In general the market for holography continues to expand rapidly worldwide and
in order to address the opportunity which this presents we continue to examine a
number of opportunities to acquire or invest in companies able to service
discreet geographic areas. This year we acquired a 25% holding in MTM Guvenlik
ve Holografik Kart Sistemleri San.Tic. A.S. (MTM) - a Turkish company well
positioned to supply both the public and private sectors in Turkey and
neighbouring countries.

<PAGE>


We announced today the proposed acquisition of Optical Security Group, Inc
("OpSec"). Full details of OpSec's business and the related equity fund-raising
are contained in a circular to shareholders which is being posted today.

PROSPECTS
We continue to anticipate a satisfactory outturn for the current year and,
equally importantly, to lay the base for significant advances in profitability
in future years resulting from the proposed merging of OpSec's operations with
our own activities.

     payment, or the second Business Day after the date on which the obligations
     of the Sponsor shall cease and determine pursuant to Clause 2.4 or be
     terminated pursuant to Clause 11.1. The Sponsor shall promptly produce to
     the Company an appropriate value added tax invoice.

           respect were the Warranties to be repeated by reference to the

<PAGE>

           facts and circumstances for the time being subsisting;

     9.5.3 forthwith to disclose in writing to the Sponsor any matter or thing
           which arises (or is reasonably likely to arise) or becomes known to
           it after the date of this Agreement and before Admission which is
           material to be known by a subscriber for any of the New Ordinary
           Shares or which is reasonably likely to give rise to a claim under
           Clause 10; and

     9.5.4 forthwith to notify the Sponsor of all other information which is
           reasonably likely to require the publication of a supplementary
           prospectus under section 147 of the FSA.

9.6  If, at any time prior to Admission, the Sponsor receives notification
     pursuant to Clause 9.5 or otherwise becomes aware that any of the
     Warranties is (or has become reasonably likely to become were the
     Warranties to be repeated by reference to the facts and circumstances for
     the time being subsisting) untrue, inaccurate or misleading to a material
     extent, the Sponsor may (without prejudice to its right to terminate its
     obligations under this Agreement pursuant to Clause 11) require the Company
     at its own expense to make or cause to be made such communication as the
     Sponsor shall reasonably consider necessary, after consultation with the
     Company, including, without limitation, the publication of a supplementary
     prospectus in accordance with section 147 of the FSA.

9.7  If a supplementary prospectus is published by the Company in connection
     with the Placing and Open Offer, Warranties relating to the Circular given
     pursuant to Clause 9.1 shall be deemed to be repeated on the date of
     publication of such supplementary prospectus and when so repeated shall be
     read and construed as if the references in Schedule 2 and this Clause 9 to
     the Circular meant the Circular when read together with such supplementary
     prospectus.

9.8  The Sponsor shall, at the Company's expense, take reasonable steps to
     mitigate any loss or liability suffered by it which is the subject of a
     claim or potential claim under the Warranties.

9.9  In the event of a claim by the Sponsor under the Warranties and without
     prejudice to any right or remedy which may be available to it, the quantum
     of the Sponsor's claim shall not be restricted to a calculation based on
     the diminution in value of any New Ordinary Shares subscribed by it under
     this Agreement.

10.  INDEMNITY

10.1 The Company will not make any claim (and will procure that no other member
     of the Group will make any claim) against the Sponsor or any of its
     affiliates to recover any loss, claim, cost, liability, expense, charge, or
     demand which the Company or any other member of the Group or its respective
     directors, officers, employees or agents or any subscriber of New Ordinary
     Shares pursuant to the Placing or the Open Offer or any subsequent
     purchaser or transferee thereof may suffer or incur by reason of or arising
     out of the carrying out by the Sponsor or on its behalf of its obligations
     and services hereunder or otherwise in connection with the Placing, or the
     Open Offer save to the extent that such loss, damage, cost, charge or
     expense arises from the fraud, negligence, or wilful default of an
     Indemnified Person (as defined in Clause 10.2) or a breach by the Sponsor
     of its obligations under this Agreement.

<PAGE>

10.2 The Company undertakes to the Sponsor for itself and as trustee for each of
     its affiliates, to indemnify and at all times to keep the Sponsor and each
     of its affiliates (each an "INDEMNIFIED PERSON") fully and effectively
     indemnified on demand (on an after tax basis) against all losses, claims,
     costs, liabilities, expenses, charges, actions or demands whatsoever which
     the Sponsor or any of its affiliates may wheresoever suffer or incur
     (including, without limitation, all such costs, charges and expenses as any
     of such persons may pay or incur in responding to, disputing or considering
     any such actual or potential actions, claims or demands or in enforcing its
     rights under this Clause 10) or which may be made or threatened against or
     incurred by the Sponsor or any of its affiliates in any jurisdiction
     whatsoever to the extent that in any such case arises directly or
     indirectly out of or results from or is attributable to:

     10.2.1 any publication, statement or communication including, without
            limitation, the Press Announcement or the Issue Documents or the
            Proxy Form not containing or being alleged not to contain all
            information required to be stated therein or any statement therein
            being or being alleged to be untrue, inaccurate, incomplete or
            misleading in any respect or as having been made negligently or
            otherwise without therequired standard of skill and care or
            reasonableness;

     10.2.2 the issue or approval of any investment advertisement (as defined
            for the purpose of section 57(2) of the FSA) issued in connection
            with the issue of the New Ordinary Shares for the purpose of
            section 57(1) of the FSA;

     10.2.3 the performance by the Sponsor or any of its affiliates of its
            obligations and services under or in connection with this Agreement
            and/or the Placing and/or the Open Offer;

     10.2.4 the making of the Placing or the Open Offer or the preparation and
            distribution of the Press Announcement or the Issue Documents or the
            Proxy Form; or

     10.2.5 any breach or alleged breach of the laws or regulations of any
            country resulting from the Placing or the Open Offer, the
            implementation of the other transactions and matters referred to
            in the Circular or the distribution of the Issue Documents in the
            manner contemplated hereby;

     and which does not in any such case arise from the negligence, wilful
     default or fraud of the Sponsor or a breach by the Sponsor of its
     obligations under this Agreement.

10.3 For the purposes of this clause, "affiliates" means any subsidiary
     undertaking or holding company of the Sponsor and any other subsidiary
     undertaking of its holding company and any of their respective directors,
     officers, agents, employees and advisers.

10.4 Any agreement or arrangement made by the Company in connection with the
     Placing or the Open Offer with any adviser excluding or limiting in any
     manner the liability of that adviser to the Company or any other person
     shall not increase the liability of the Sponsor or any Indemnified Person
     to the Company, and the Company shall not be entitled to recover from the
     Sponsor or any Indemnified Person any amount which, if such exclusion or
     limitation had not been agreed, the Sponsor would have been entitled to
     recover from that adviser pursuant to the Civil Liability (Contribution)
     Act 1978.

<PAGE>

10.5 Save in the event of a breach of any Warranty, Clauses 9 and 10 shall not
     apply with respect to any trading losses of the Sponsor arising in relation
     to any New Ordinary Shares acquired pursuant to its underwriting
     obligations under Clause 5.1.3. Save as set out above, the Sponsor shall
     have, in addition to its rights under Clauses 9 and 10, the same rights and
     remedies pursuant to Part IV of the FSA in relation to any New Ordinary
     Shares subscribed by it hereunder as any other subscriber for New Ordinary
     Shares, and the provisions of this Agreement shall be without prejudice to
     the statutory rights of the Sponsor in respect to such subscription.

10.6 The indemnities contained in this Clause 10 shall extend to any payments
     made by the Sponsor or any loss suffered as a result of any reasonable
     action taken by the Sponsor (including, without limitation, the purchase of
     any Ordinary Shares by the Sponsor (other than purchases made by the
     Sponsor for its own investment purposes or shares acquired pursuant to its
     underwriting obligations under Clause 5.1.3)) notwithstanding that the
     Sponsor may be under no legal obligation to make such payment or take such
     action.

11.  TERMINATION

11.1 If at any time prior to Admission:

     11.1.1 it shall come to the notice of the Sponsor that any statement
            contained in the Circular is untrue or incorrect or misleading in
            any respect or that matters have arisen which would, if the Circular
            were issued at that time, constitute a material omission therefrom;
            or

     11.1.2 it shall come to the notice of the Sponsor that a matter has arisen
            which might give rise to a claim under the indemnity in Clause 10.2
            or that any of the Warranties was untrue or inaccurate or misleading
            in any respect when given and/or that any of the Warranties has
            at the relevant time ceased to be true or accurate or has become
            misleading in any respect by reference to the facts and
            circumstances for the time being subsisting, so as (in the
            reasonable opinion of the Sponsor) to result in the Circular being
            or becoming misleading in any material respect, or as to make it
            otherwise commercially inadvisable (based on an objective investment
            decision) to proceed with the Placing or the Open Offer; or

     11.1.3 the Company fails in any material respect to comply with any of its
            obligations under this Agreement,

     then and in any such case the Sponsor may, following reasonable
     consultation with the Company (including considering whether it would
     be appropriate to issue a supplementary prospectus), in its absolute
     discretion give notice in writing to the Company to terminate this
     Agreement and its obligations hereunder save to the extent specified
     in Clause 11.2 (and, for the avoidance of doubt, the Sponsor shall not
     be required to wait until Admission to exercise any right arising
     pursuant to Clause 11.1.2).

11.2 If the obligations of the Sponsor or the Company under this Agreement (save
     to the extent specified in this Clause 11.2) shall cease or determine
     pursuant to Clause 2.4 or be terminated

<PAGE>

     pursuant to Clause 11.1, no party will have any claim against any other for
     compensation, costs, damages or otherwise (except in relation to any
     breaches prior to such determination or termination) save that:

     11.2.1 the Company shall pay the expenses and costs and fees and
            commissions referred to in Clause 8 (together with any value added
            tax payable thereon); and

     11.2.2 the provisions of Clauses 1, 9, 10, 11.2 and 12 to 24 inclusive
            shall remain in full force and effect notwithstanding such
            termination or determination.

12.  ANNOUNCEMENTS AND COVENANTS

12.1 Save as required by law or the Listing Rules or the requirements of any
     relevant regulatory authority:

     12.1.1 the Company undertakes to the Sponsor that it will hold no press
            conferences and will not make any public announcement or
            communication concerning this Agreement, the Company, the Open
            Offer or the Placing (other than the publication of the documents
            referred to in this Agreement) or otherwise relating to the
            financial condition or trading or financial prospects of the Company
            between the date of this Agreement and forty days after Admission,
            whether in response to enquiries or otherwise, without the prior
            approval of the Sponsor (such approval not to be unreasonably
            withheld or delayed);

     12.1.2 no announcement, statement or communication to shareholders (other
            than the Press Announcement, the Issue Documents and the Proxy Form)
            concerning the Company or any other members of the Group or in
            connection with the Issue Documents or the New Ordinary Shares will
            be made or despatched by the Company or any other members of the
            Group to any third party between the date of this Agreement and
            forty days after Admission without the prior approval of the Sponsor
            such approval not to be unreasonably withheld or delayed;

     12.1.3 the Company will not (and will procure that no member of the Group
            will) between the date of this Agreement and forty days after
            Admission enter into any commitment or agreement which it is obliged
            to announce or put itself into a position where it is obliged to
            announce that any commitment or agreement may be entered into
            without (in each case) the prior approval of the Sponsor such
            approval not to be unreasonably withheld or delayed; and

     12.1.4 save as set out in the Circular, the Company will not (and will
            procure that no member of the Group will) issue any share or right
            to be allotted any share or agree to do any such thing between the
            date of this Agreement and forty days after Admission without the
            prior approval of the Sponsor such approval not to be unreasonably
            withheld or delayed.

12.2 The Company agrees and undertakes to perform and implement each of the
     OpSec Merger Agreement and Tender Offer in accordance with its provisions
     and to use all reasonable endeavours to ensure that the Opsec Merger and
     the Tender Offer complete according to the

<PAGE>

     timetable set out in the Circular. The Company undertakes to take such
     steps as may be reasonably required to enforce or procure the exercise of
     any undertakings or rights contained in the OpSec Merger Agreement and/or
     Tender Offer and/or any document entered into pursuant thereto or in
     connection therewith. The Company undertakes to the Sponsor that it will
     not materially alter, revise or amend or agree any material alteration,
     revision or amendment of any of the terms of the OpSec Merger Agreement
     and/or Tender Offer (or any document entered into pursuant thereto or in
     connection therewith) or (where material) waive any condition or exercise
     any discretion pursuant thereto or grant any time for performance or other
     indulgence thereunder or proceed to completion of the Opsec Merger without
     the full satisfaction of each of the terms and conditions in the OpSec
     Merger Agreement without the prior approval of the Sponsor, such approval
     not to be unreasonably withheld or delayed. In the event of any claim, suit
     or proceedings by any third party, regulatory authority or otherwise which
     may have the effect of interfering with or delaying the Opsec Merger or
     Tender Offer, all proposed actions which are material taken by (or approved
     by) the Company shall be promptly notified to the Sponsor and no action
     shall be taken without the Sponsor's prior approval, such approval not to
     be unreasonably withheld or delayed.

13.  WITHHOLDING

     All sums payable to the Sponsor under this Agreement shall be paid without
     any set off or counterclaim and free and clear of all deductions or
     withholdings unless the deduction or withholding is required by law, in
     which event the relevant person shall pay such additional amount as shall
     be required to ensure that the net amount received by the Sponsor will
     equal the full amount which would have been received by it had no such
     deduction or withholding been made.

14.  REMEDIES AND ENFORCEMENT

14.1 This Agreement shall (except for any obligation fully performed) remain in
     full force and effect notwithstanding the completion of this Agreement, the
     Open Offer, the Placing and the subscription of the New Ordinary Shares
     pursuant thereto.

14.2 The Warranties and the indemnities herein contained shall be in addition
     to, and shall not be construed to limit, affect or prejudice, any other
     right or remedy available to the Sponsor or any Indemnified Person.

14.3 In exercising any right or power as trustee of an Indemnified Person under
     this Agreement, the Sponsor shall be entitled to act in such manner as it
     shall in its absolute discretion consider appropriate.

15.  INVALIDITY

     Each of the provisions of this Agreement is severable and distinct from the
     others and the invalidity, illegality or unenforceability of any one or
     more of the provisions of this Agreement shall not affect the continuation
     in force of the remaining provisions of this Agreement.

     preclude or restrict any other or further exercise of such right or remedy
     or the exercise of any other right or remedy. The rights and remedies

     audited accounts of the Company for the two years ended 31 March 1998 and
     31 March 1999 and the accounting policies and practices set out in such
     accounts and in a manner similar to the preparation of interim results in
     the previous two financial years of the Company and, so far as the
     Directors are aware, have been prepared with due care and attention and are
     based on reasonable assumptions.

2.2  So far as the Directors are aware, there is no fact or circumstance the
     existence of which would make the Interim Results materially inaccurate or
     misleading.

     statement referred to therein the Directors have taken full account of all
     matters set out in the Working Capital Report.

     The information contained in the replies to the Verification Notes is true
     and accurate in all material respects and not misleading in any material
     respect and no information has been omitted from such replies the absence

8.   OTHER EVENTS OF DEFAULT

     No event has occurred or is subsisting or (so far as the Directors are
     aware) is about to occur which constitutes or results in, or would with the
     giving of notice and/or the lapse of time and/or the satisfaction of any
     other condition constitute or result in termination of, or a default or the
     acceleration of any obligation under, any agreement, instrument or
     arrangement to which any Group Company is a party or by which it or any of
     its properties, revenues or assets are bound and which would in any such

     trading position, assets or prospects of the Group as a whole.

9.   INSOLVENCY

     No member of the Group has taken any action nor has the Company received
     notice that any other steps have been taken or legal proceedings have

     arrangement or composition for the benefit of creditors or for the
     appointment of an administrator, a receiver, trustee or similar officer of

<PAGE>

     carrying on of its business and such Authorities have at all times been and

     Group Company has complied (whether retrospectively or otherwise) with all
     material legal and regulatory requirements applicable to its business.

     potential investors in the Company concerning actual or potential conflicts
     of interest between any Group Company and any Director or any Related

     conflict or concerning the future relationship with such Director or

                          AGREEMENT AND PLAN OF MERGER

         AGREEMENT AND PLAN OF MERGER (this "AGREEMENT") is made and entered
into as of this 30th day of November, 1999, by and among Applied Holographics
plc, a public limited company incorporated and existing under the laws of
England and Wales ("BUYER"), Applied OpSec Corporation, a Colorado corporation,
and a direct wholly-owned subsidiary of Buyer ("NEWCO"), and Optical Security
Group, Inc., a Colorado corporation ("SELLER").

                                    RECITALS

         WHEREAS, Buyer and Seller have agreed that Buyer shall acquire Seller
by causing Newco, which has been formed for the express purpose of consummating
the transactions contemplated hereby, to merge with and into Seller (the
"MERGER"), with Seller as the surviving corporation of the Merger, upon the
terms and subject to the conditions set forth herein, all in accordance with the
Colorado Business Corporation Act (the "CBCA").

         WHEREAS, substantially concurrently herewith and as a condition and
inducement to Buyer's willingness to enter into this Agreement, Buyer and
certain stockholders of Seller, who include certain of the directors and
officers of Seller and its Subsidiaries (as defined herein) who hold, in the
aggregate, approximately 35.2% of the outstanding shares of common stock, par
value $.005, of Seller (the "SELLER COMMON STOCK"), are entering into
Stockholder Agreements in the form of EXHIBIT A hereto (the "STOCKHOLDER
AGREEMENTS").

         WHEREAS, as a condition and inducement to Buyer to enter into, and
after the execution of, this Agreement, Buyer and Seller are entering into the
Seller Option Agreement ("SELLER OPTION AGREEMENT"), attached hereto as EXHIBIT
B, pursuant to which Seller has granted an option to purchase shares of Seller
Common Stock ("SELLER OPTION") to Buyer.

         WHEREAS, in furtherance of the acquisition of Seller by Buyer on the
terms and subject to the conditions set forth in this Agreement, Buyer proposes
to cause Newco to make a tender offer (as it may be amended from time to time as
permitted under this Agreement, the "OFFER") to purchase all of the outstanding
shares of Seller Common Stock, at a purchase price of $7.00 per share (the
"OFFER PRICE"), without interest thereon, upon the terms and subject to the
conditions set forth in this Agreement.

         WHEREAS, the Boards of Directors of Buyer, Newco and Seller have
determined that the Offer, this Agreement and the Merger are advisable and in
the best interests of Buyer, Newco and Seller and their respective stockholders.
The Boards of Directors of each of Buyer, Newco and Seller have approved the
Offer, this Agreement and the Merger. The Board of Directors of Seller has
resolved to recommend to the stockholders of Seller to vote in favor of this

Merger.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained and for other good and valuable consideration the
receipt and sufficiency of which are hereby acknowledged, Buyer, Newco and
Seller hereby agree as follows:

                                    ARTICLE I

                                    THE OFFER

         1.01.    THE OFFER.


<PAGE>

         (a) Subject to the provisions of this Agreement, as promptly as
practicable, but in no event later than five (5) business days after the date of
the public announcement by Buyer and Seller of this Agreement, Buyer shall cause
Newco to commence the Offer. The initial expiration date for the Offer shall be
the 20th business day following the commencement of the Offer. The obligation of
Newco to accept for payment, and pay for, any shares of Seller Common Stock
tendered pursuant to the Offer shall be subject to the conditions set forth in
EXHIBIT C hereto (the "OFFER CONDITIONS") (any of which may be waived in whole
or in part by Buyer in its sole discretion) and to the terms and conditions of
this Agreement.

         (b) Buyer may, without the consent of Seller, cause Newco to (A)
extend the Offer, if at the scheduled or extended expiration date of the
Offer any of the Offer Conditions shall not be satisfied or waived, until
such time as such conditions are satisfied or waived, (B) extend the Offer
for any period required by any rule, regulation, interpretation or position
of the U.S. Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer or any period required by applicable law and
(C) extend the Offer on one or more occasions for an aggregate period of not
more than ten (10) business days beyond the latest expiration date that would
otherwise be permitted under clause (A) or (B) of this sentence, if on such
expiration date there shall not have been tendered at least 90% of the
outstanding shares of Seller Common Stock. Subject to the terms and
conditions of the Offer and this Agreement, Buyer shall cause Newco to accept
for payment, and pay for, all shares of Seller Common Stock validly tendered
and not withdrawn pursuant to the Offer that Newco becomes obligated to
accept for payment and pay for, pursuant to the Offer as promptly as
practicable after the expiration of the Offer.

         (c) On the date of commencement of the Offer, Buyer shall cause Newco
to file with the SEC a Tender Offer Statement on Schedule 14D-1 (the "SCHEDULE
14D-1") with respect to the Offer, which shall contain an offer to purchase and
a related letter of transmittal and summary advertisement (such Schedule 14D-1
and the documents included therein pursuant to which the Offer shall be made,
together with any supplements or amendments thereto, the "OFFER DOCUMENTS"). The
Offer Documents shall comply as to form in all material respects with the
requirements of the Exchange Act (as defined herein) and the rules and
regulations promulgated thereunder and the Offer Documents, on the date first
published, sent or given to the holders of shares of Seller Common Stock, shall
not 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. Each of Buyer, Newco and Seller agree promptly to correct any
information provided by it for use in the Offer Documents if and to the extent
that such information shall have become false or misleading in any material
respect, and Buyer further agrees to cause Newco to take all steps necessary to
cause the Schedule 14D-1 as so corrected to be filed with the SEC and the other
Offer Documents as so corrected to be disseminated to holders of Seller Common
Stock, in each case as and to the extent required by applicable federal
securities laws. Seller and its counsel shall be given reasonable opportunity to
review and comment upon the Offer Documents prior to their filing with the SEC
or dissemination to the holders of Seller Common Stock. Buyer agrees to cause
Newco to provide Seller and its counsel any comments Buyer, Newco or their
counsel may receive from the SEC or its staff with respect to the Offer
Documents promptly after the receipt of such comments.

         1.02.    SELLER ACTIONS.

         (a) Seller hereby approves of, and consents to, the Offer and
represents that the Board of Directors of Seller, at a meeting duly called and
held, duly and unanimously adopted resolutions approving this Agreement, the
Offer and the Merger, determining, as of the date of such resolutions, that the
terms of the Offer are fair to, and in the best interests of, the holders of
Seller Common Stock, recommending that the holders of Seller Common Stock accept
the Offer, tender their shares of Seller Common Stock pursuant to the Offer and
approve this Agreement (if required) and approving the acquisition of shares of
Seller Common Stock by Newco pursuant to the Offer and the other transactions
contemplated by this Agreement, including the Merger. Seller

of Seller Common Stock (each of whom is listed in Section 1.02(a) of the Seller
Disclosure Schedule) that such person currently intends to tender all shares of
Seller Common Stock.

         (b) On the date the Offer Documents are filed with the SEC, Seller
shall file with the SEC a Solicitation/Recommendation Statement on Schedule
14D-9 with respect to the Offer (such Schedule 14D-9, as supplemented or amended
from time to time, the "SCHEDULE 14D-9") containing, subject to the terms of
this Agreement, the recommendation described in paragraph (a) and shall mail the
Schedule 14D-9 to the holders of shares of Seller Common Stock. The Schedule
14D-9 shall comply as to form in all material respects with the requirements of
the Exchange Act and the rules and regulations promulgated thereunder and, on
the date filed with the SEC and on the date first published, sent or given to
the holders of Seller Common Stock, shall not 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. Each of Buyer, Newco
and Seller agrees promptly to correct any information provided by it for use in
the Schedule 14D-9 if and to the extent that such information shall have become
false or misleading in any material respect, and Seller further agrees to take
all steps necessary to amend or supplement the Schedule 14D-9 and to cause the
Schedule 14D-9 as so amended or supplemented to be filed with the SEC and
disseminated to the holders of the Shares, in each case as and to the extent
required by applicable federal securities laws. Buyer, Newco and their counsel
shall be given reasonable opportunity to review and comment upon the Schedule
14D-9 prior to its filing with the SEC or dissemination to the holders of Seller
Common Stock. Seller agrees to provide Buyer, Newco and their counsel any
comments Seller or its counsel may receive from the SEC or its staff with
respect to the Schedule 14D-9 promptly after the receipt of such comments.

         (c) In connection with the Offer and the Merger, Seller shall cause its
transfer agent to furnish Buyer promptly with mailing labels containing the
names and addresses of the record holders of Seller Common Stock as of a recent
date and of those persons becoming record holders subsequent to such date,
together with copies of all lists of stockholders, security position listings
and computer files and all other information in Seller's possession or control
regarding the beneficial owners of shares of Seller Common Stock, and shall
furnish to Buyer such information and assistance (including updated lists of
stockholders, security position listings and computer files) as Buyer may
reasonably request in communicating the Offer to the holders of shares of Seller
Common Stock. Subject to the requirements of applicable law, and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Merger, Buyer and each of its agents shall
hold in confidence the information contained in any such labels, listings and
files, will use such information only in connection with the Offer and the
Merger and, if this Agreement shall be terminated, will deliver, and will use
their reasonable efforts to cause their agents to deliver, to Seller all copies
and any extracts or summaries from such information then in their possession or
control.

                                   ARTICLE II

                                   THE MERGER

         2.01. THE MERGER. At the Effective Time (as defined in Section 2.03
hereof), in accordance with this Agreement and the CBCA, Newco shall be merged
with and into Seller, the separate existence of Newco (except as may be
continued by operation of law) shall cease, and Seller shall continue as the
surviving corporation under the corporate name it possesses immediately prior to
the Effective Time, as a wholly-owned subsidiary of Buyer. Seller after the
Merger hereinafter sometimes is referred to as the "SURVIVING CORPORATION."

         2.02. EFFECT OF THE MERGER. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of this Agreement and
the CBCA. Without limiting the generality of the foregoing, and subject thereto,
at the Effective Time all the rights and property of Seller and Newco (the
"CONSTITUENT CORPORATIONS") shall vest in the Surviving Corporation, and all
debts and liabilities of Seller and Newco shall become the debts and liabilities
of the Surviving Corporation.


<PAGE>

         2.03. CONSUMMATION OF THE MERGER. In the event of, and as soon as is
practicable after, the satisfaction or waiver of the conditions set forth in
Article VI hereof, the parties hereto will cause the Merger to be consummated by
filing, with the Secretary of State of Colorado, Articles of Merger (the time of
confirmation of such filing or such later time as is specified in such Articles
of Merger being the "EFFECTIVE TIME"). Contemporaneous with the filing referred
to in this Section 2.03, a closing (the "CLOSING") will be held at the offices
of Bingham Dana LLP, 150 Federal Street, Boston, Massachusetts 02110 or at such
other location as the parties may establish for the purpose of confirming all
the foregoing. The date and the time of such Closing are referred to as the
"CLOSING DATE."

         2.04. CHARTER; BYLAWS; DIRECTORS AND OFFICERS. Unless otherwise
determined by Buyer prior to the Effective Time, the Articles of Organization
and Bylaws of the Surviving Corporation shall be the Articles of Organization
and Bylaws of Seller, as in effect immediately prior to the Effective Time,
until thereafter amended as provided therein and under the CBCA. The directors
of Newco immediately prior to the Effective Time will be the initial directors
of the Surviving Corporation, and the officers of Newco immediately prior to the
Effective Time will be the initial officers of the Surviving Corporation, in
each case until their successors are elected and qualified.

         2.05.    EFFECT ON OUTSTANDING SECURITIES.

         (a) NEWCO COMMON STOCK. By virtue of the Merger, automatically and
without any action on the part of any Person, including without limitation the
holder thereof, each share of common stock, par value $.01 per share, of Newco
("NEWCO COMMON STOCK") issued and outstanding immediately prior to the Effective
Time shall be converted into and become one validly issued, fully paid and
nonassessable share of common stock, par value $.01 per share, of the Surviving
Corporation.

         (b) SELLER COMMON STOCK. By virtue of the Merger, automatically and
without any action on the part of any Person, including without limitation the
holder thereof, each of the shares of Seller Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares of Seller Common
Stock to be cancelled pursuant to Section 2.05(d) hereof and any Dissenting
Shares (as defined in Section 2.08)), shall be cancelled and extinguished and be
automatically converted into and become a right to receive an amount per share
in cash (the "COMMON STOCK MERGER CONSIDERATION") equal to $7.00, upon surrender
in the manner provided in Section 2.09 of the certificate that evidenced the
shares of Seller Common Stock (a "COMMON STOCK CERTIFICATE").

         (c) SELLER PREFERRED STOCK. By virtue of the Merger, automatically and
without any action on the part of any Person, including without limitation the
holder thereof, each of the shares of Series B 8% Convertible Preferred Voting
Stock of Seller ("SELLER PREFERRED STOCK") issued and outstanding immediately
prior to the Effective Time (other than any Dissenting Shares (as hereinafter
defined)), shall be cancelled and extinguished and be automatically converted
into and become a right to receive an amount per share in cash (the "PREFERRED
STOCK MERGER CONSIDERATION", and, together with the Common Stock Merger
Consideration, the "MERGER CONSIDERATION") equal to the product of (i) the
number of shares of Seller Common Stock into which such share of Seller
Preferred Stock is convertible MULTIPLIED BY (ii) the Common Stock Merger
Consideration, upon surrender in the manner provided in Section 2.09 of the
certificate that evidenced the shares of Seller Preferred Stock (a "PREFERRED
STOCK CERTIFICATE," and, together with the Common Stock Certificates, the
"CERTIFICATES").

         (d) TREASURY STOCK; SHARES OWNED BY BUYER OR SELLER. Each share of
Seller Common Stock which is issued and held in the treasury of Seller
immediately prior to the Effective Time or issued and outstanding and owned by
Buyer or any direct or indirect Subsidiary (as defined in Article VIII) of Buyer
or Seller, shall be cancelled and retired, and no payment shall be made with
respect thereto.

         (e) DISSENTING SHARES. The holders of Dissenting Shares, if any, shall
be entitled to payment for such shares only to the extent permitted by and in
accordance with the provisions of the CBCA; provided,


<PAGE>

however, that if, in accordance with the applicable provisions of the CBCA, any
holder of Dissenting Shares shall forfeit such right to payment of the fair cash
value of such shares, such shares shall thereupon be deemed to have been
converted into and to have become exchangeable for, as of the Effective Time,
the right to receive the Merger Consideration applicable thereto as provided in
Section 2.05(b) or (c), as the case may be.

         2.06.    SELLER STOCK OPTIONS, WARRANTS AND RELATED MATTERS.

         (a) Prior to the Effective Time, Seller shall terminate Seller's
Incentive Stock Option Plan, Nonqualified Stock Option Plan and Stock Bonus Plan
(collectively, the "SELLER EQUITY PLANS"), and, in connection therewith, shall
provide written notice to each holder of a then outstanding stock option (each,
an "OPTION") to purchase shares of Seller Common Stock pursuant to the Seller
Equity Plans (whether or not such Option is then vested or exercisable), that
such Option shall be, as of the date of such notice, exercisable in full and
that such Option shall terminate at the Effective Time and that, if such Option
is not exercised or otherwise terminated before the Effective Time, such holder
shall be entitled to receive in cancellation of such Option a cash payment from
Buyer promptly after the Effective Time, in an amount equal to the excess of the
Common Stock Merger Consideration over the per share exercise price of such
Option, if any, multiplied by the number of shares covered by such Option (the
"OPTION SETTLEMENT AMOUNT"), subject to income tax withholding as required by
applicable law. The Seller Disclosure Schedule includes a complete listing of
Options held by each optionee (including the date of grant, the number of shares
issuable upon exercise of the Option, and the Option Settlement Amount to which
the Optionee is entitled). Except as otherwise provided in this Section 2.06(a),
Seller shall not grant or amend any Option after the date hereof. Seller hereby
represents and warrants to Buyer that the number of shares of Seller Common
Stock subject to issuance pursuant to the exercise of Options issued and
outstanding under the Seller Equity Plans is, and shall be as of the Effective
Time, not in excess of 2,154,712. To the extent that the cancellation of any
Option pursuant to this Section 2.06(a) requires the agreement of the holder of
such Option under a Seller Equity Plan, Seller shall use commercially reasonable
efforts, including taking reasonable instructions from Buyer, to enter into an
agreement with such holder providing for the cancellation of such Option in
consideration for the receipt by such holder of the applicable Option Settlement
Amount with respect to such Option. Buyer acknowledges and agrees that the
failure of Seller to obtain any required agreement of a holder of an Option to
the provisions of this Section 2.06(a) after using its commercially reasonable
efforts to do so, shall not be deemed to be a breach by Seller of this Agreement
but shall be relevant in determining whether or not Seller has satisfied its
obligations under this Agreement for purposes of Section 6.02(b) hereof.

         (b) Prior to the Effective Time, Seller shall use its commercially
reasonable efforts, including taking reasonable instructions from Buyer, to
receive from each holder of an outstanding warrant (each, a "WARRANT") to
purchase shares of Seller Common Stock an agreement that, as of the Effective
Time, such Warrant shall be converted into a right of such holder to receive
from Buyer promptly after the Effective Time the consideration set forth in the
next sentence. Each holder of a Warrant shall be entitled to receive from Buyer
in respect of the shares of Seller Common Stock to be issued upon the exercise
of such Warrant, an amount in cash, without interest (the "WARRANT
CONSIDERATION"), equal to the product of (i) the number of shares of Seller
Common Stock subject to such Warrant immediately prior to the Effective Time and
(ii) the excess, if any, by which the Common Stock Merger Consideration exceeds
the exercise price per share that was applicable with respect to such Warrant.
Seller hereby represents and warrants to Buyer that the number of shares of
Seller Common Stock subject to issuance pursuant to the Warrants is, and shall
be as of the Effective Time, not in excess of 1,152,457. Buyer acknowledges and
agrees that the failure of Seller to obtain the agreements with each holder of a
Warrant described in this Section 2.06(b) after using its commercially
reasonable efforts to do so, shall not be deemed to be a breach by Seller of
this Agreement but shall be relevant in determining whether or not Seller has
satisfied its obligations under this Agreement for purposes of Section 6.02(b)
hereof.

         (c) Simultaneously with the execution of this Agreement, Seller and
Richard H. Bard are entering an amendment to Mr. Bard's employment agreement
(the "AMENDMENT"), which Amendment shall not be amended or otherwise changed
without the prior written consent of Buyer. In addition, promptly after the
Effective Time, Buyer shall pay to Mr. Bard an amount in cash equal to $250,000
in settlement of certain


<PAGE>

Options held by Mr. Bard under a Seller Equity Plan. Also, in satisfaction of
certain rights of Mr. Bard to receive shares of Seller Common Stock upon a
merger or acquisition of Seller as described in paragraph 3-5 of Mr. Bard's
employment agreement, and as otherwise allocated in a manner to be agreed upon
by the parties, Buyer shall pay to Mr. Bard promptly after the Effective Time an
amount in cash equal to $3,500,000.

         2.07.    CANCELLATION OF CONVERTIBLE DEBENTURES.

         (a) Prior to the Effective Time, Seller shall use its commercially
reasonable efforts to receive from each holder (each, a "DEBENTURE HOLDER") of
an outstanding debenture (each, a "DEBENTURE") an agreement that, simultaneously
with the consummation of the Merger and at the Effective Time, the Debenture
then held by it shall (automatically and without further action by the Debenture
Holder) be cancelled and deemed to be paid-in-full and each Debenture Holder
shall be entitled to receive as payment therefor the consideration set forth in
Sections 2.07(c) and (d) below. Buyer acknowledges and agrees that the failure
of Seller to obtain the agreements with each Debenture Holder described in this
Section 2.07(a) after using its best efforts and taking all actions necessary to
do so, shall not be deemed to be a failure of Seller to satisfy its covenants
and other agreements contained herein for purposes of Section 6.02(b) hereof.

         (b) At the Closing, each Debenture Holder who shall have agreed to the
cancellation of the Debenture held by such holder pursuant to Section 2.07(a)
hereof, shall deliver the original Debenture held by it for cancellation in
accordance with this Section 2.07. At the Effective Time, and subject to and
upon delivery and cancellation of such original Debenture, Buyer shall pay to
such Debenture Holder the consideration to which such Debenture Holder is
entitled, pursuant to Sections 2.07(c) and (d) below, as payment for, and in
full satisfaction of, all amounts owed by Seller thereunder. From and after the
Effective Time, none of Buyer, Newco or Seller shall have any liability or
obligation of any kind whatsoever under the Debentures to the extent that a
Debenture Holder shall have agreed to the cancellation of his, her or its
Debenture pursuant to this Section 2.07.

         (c) Subject to the provisions of this Section 2.07, promptly after the
Effective Time, Buyer shall pay to each Debenture Holder of a Debenture with a
strike price of $6.00 who shall have entered into an agreement with Seller for
the cancellation of such holder's Debenture, an amount in cash equal to 116.67%
of such Debenture Holders' pro-rata share of the outstanding principal amount of
such Debenture, together with accrued interest thereon as provided in the
applicable Debenture. The maximum aggregate consideration payable to the
Debenture Holders of Debentures with a strike price of $6.00 by Buyer, assuming
that all such Debenture Holders enter into agreements with Seller for the
cancellation of such holders' Debentures, shall be $583,350.

         (d) Subject to the provisions of this Section 2.07, promptly after the
Effective Time, Buyer shall pay to each Debenture Holder of a Debenture with a
strike price of $6.50 who shall have entered into an agreement with Seller for
the cancellation of such holder's Debenture, an amount in cash equal to 109% of
such Debenture Holders' pro-rata share of the outstanding principal amount of
such Debenture, together with accrued interest thereon as provided in the
applicable Debenture. The maximum aggregate consideration payable to the
Debenture Holders of Debentures with a strike price of $6.50 by Buyer, assuming
that all such Debenture Holders enter into agreements with Seller for the
cancellation of such holders' Debentures, shall be $3,019,300.

         2.08.    DISSENTING SHARES.

         (a) Notwithstanding any provision of this Agreement to the contrary,
holders of Seller Common Stock and Seller Preferred Stock which are entitled to
dissenter's rights in connection with the Merger under the CBCA (collectively,
the "DISSENTING SHARES") shall not be converted into or represent the right to
receive the Merger Consideration applicable to such shares. Such stockholders
shall be entitled to receive payment of the fair market value of such Dissenting
Shares held by them in accordance with the provisions of the CBCA, except that
all Dissenting Shares held by stockholders who shall have failed to perfect or
who effectively shall have withdrawn or lost their rights to the payment of fair
market value for such shares under the CBCA shall


<PAGE>

thereupon be deemed to have been converted into and to have become exchangeable
for, as of the Effective Time, the right to receive the Merger Consideration
applicable to such shares, without any interest thereon, upon surrender, in the
manner provided in Section 2.09, of the certificate or certificates that
formerly evidenced such shares.

         (b) Seller shall give Buyer (i) prompt notice of any demand for payment
of fair market value received by Seller, the withdrawals of any such demand, and
any other instrument served pursuant to the CBCA and received by Seller and (ii)
the opportunity to direct all negotiations and proceedings with respect to
demands for payment of fair market value under the CBCA. Seller shall not,
except with the prior written consent of Buyer, make any payment with respect to
any demands for payment of fair market value or offer to settle or settle any
such demands.

         2.09.    EXCHANGE OF CERTIFICATES.

         (a) From and after the Effective Time, a bank or trust company to be
designated by Buyer (the "EXCHANGE AGENT") shall act as exchange agent in
effecting the exchange of the Merger Consideration for Certificates which, prior
to the Effective Time, represented shares of Seller Common Stock or Seller
Preferred Stock, as the case may be, entitled to payment pursuant to Section
2.05 hereof. At or immediately prior to the Effective Time, Buyer shall deposit
with the Exchange Agent the aggregate Merger Consideration necessary to make the
payments contemplated hereby on a timely basis (the "DEPOSIT AMOUNT") in trust
for the benefit of the holders of Certificates. Upon the surrender of each such
Certificate and the issuance and delivery by the Exchange Agent of the Merger
Consideration applicable thereto in exchange therefor, such Certificate shall
forthwith be cancelled. Until so surrendered and exchanged, each such
Certificate (other than Certificates representing shares held by Buyer or Seller
or any direct or indirect Subsidiary of Buyer or Seller and Dissenting Shares)
shall represent solely the right to receive the Merger Consideration applicable
thereto, without interest, multiplied by the number of shares represented by
such Certificate. Promptly after the Effective Time, the Exchange Agent shall
mail to each record holder of Certificates which immediately prior to the
Effective Time represented shares a form of letter of transmittal and
instructions for use in surrendering such Certificates and receiving the Merger
Consideration applicable thereto. Upon the surrender to the Exchange Agent of
such an outstanding Certificate together with such letter of transmittal, duly
completed and validly executed in accordance with the instructions thereto, and
such other documents as may be required pursuant to such instructions, the
holder shall receive the Merger Consideration applicable thereto, without any
interest thereon and such Certificate shall be cancelled. If any Merger
Consideration is to be paid to a name other than the name in which the
Certificate representing shares surrendered in exchange therefor is registered,
it shall be a condition to such payment or exchange that the Person requesting
such payment or exchange shall pay to the Exchange Agent any transfer or other
taxes required by reason of the payment of such Merger Consideration to a name
other than that of the registered holder of the Certificate surrendered, or such
Person shall establish to the satisfaction of the Exchange Agent that such tax
has been paid or is not applicable. Notwithstanding the foregoing, neither the
Exchange Agent nor any party hereto shall be liable to a holder of shares for
any Merger Consideration delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

         (b) Buyer shall not be entitled to the return of any of the Deposit
Amount in the possession of the Exchange Agent relating to the transactions
described in this Agreement until the date which is 180 days after the Effective
Time. Thereafter, each holder of a Certificate representing a share may
surrender such Certificate to the Surviving Corporation and (subject to
applicable abandoned property, escheat and similar laws) receive in exchange
therefor the Merger Consideration applicable thereto, without any interest
thereon, but shall have no greater rights against the Surviving Corporation than
may be accorded to general creditors of the Surviving Corporation.

         (c) At and after the Effective Time, the holders of Certificates to be
exchanged for the Merger Consideration applicable thereto pursuant to this
Agreement shall cease to have any rights as to stockholders of Seller except for
the right to surrender such holder's Certificates in exchange for payment of the
Merger Consideration applicable thereto, and after the Effective Time there
shall be no transfers on the stock transfer


<PAGE>

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 cancelled and exchanged for the Merger Consideration applicable
thereto, as provided in this Article II, subject to applicable law in the case
of Dissenting Shares.

         (d) If 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 subject to such other conditions as the
Buyer may impose, the Exchange Agent shall pay in exchange for such lost, stolen
or destroyed Certificate the Merger Consideration deliverable in respect of such
Certificate as determined in accordance herewith. When authorizing such payment
of the Merger Consideration in exchange for such Certificate, the Buyer (or any
authorized officer thereof) may, in its reasonable discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificate to deliver to the Surviving Corporation a bond in such sum
as the Surviving Corporation may reasonably require as indemnity against any
claim that may be made against Buyer, the Surviving Corporation or the Exchange
Agent with respect to the Certificate alleged to have been lost, stolen or
destroyed.

         (e) The provisions of this Section 2.09 shall also apply to Dissenting
Shares that lose their status as such, except that the obligations of Exchange
Agent under this Section 2.09 shall commence on the date of loss of such status.

         2.10. SUPPLEMENTARY ACTION. If, at any time after the Effective Time,
any further assignments or assurances in law or any other things are necessary
or desirable to vest or to perfect or confirm of record in the Surviving
Corporation the title to any property or rights of either Seller or Newco, or
otherwise to carry out the provisions of this Agreement, the officers and
directors of the Surviving Corporation are hereby authorized and empowered, in
the name of and on behalf of Seller and Newco, to execute and deliver any and
all things necessary or proper to vest or to perfect or confirm title to such
property or rights in the Surviving Corporation, and otherwise to carry out the
purposes and provisions of this Agreement.

         2.11. POSSIBLE ALTERNATIVE STRUCTURE. Notwithstanding any other
provision of this Agreement to the contrary, prior to the Effective Time, Buyer
shall be entitled to revise the structure of the transaction to provide that
Seller shall be merged with and into Newco at the Effective Time, with Newco as
the surviving corporation of the Merger. Notwithstanding the foregoing or any
other provision of this Agreement to the contrary, Buyer and Seller may jointly
elect prior to the Effective Time, to substitute an alternative structure for
the accomplishment of the transactions contemplated by this Agreement; it being
understood by Buyer and Seller that any change to the structure of the Merger
pursuant to this Section 2.11 shall not be adopted if such change would (a)
materially delay consummation of the Merger, (b) change the amount or form of
consideration to be received by the stockholders of Seller or (c) have an
adverse impact on the financial benefits reasonably expected to be derived by,
or affect the obligations of Seller to, the security holders (Seller Common
Stock, Seller Preferred Stock, Options, Debentures and Warrants) of Seller from
the transactions provided for herein. Buyer and Seller agree that this Agreement
shall be appropriately amended in order to reflect any alternative structure.

                                   ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller represents and warrants to Buyer and Newco that, except as
described in the applicable section of the Seller Disclosure Schedule furnished
by Seller to Buyer prior to the execution of this Agreement (the "SELLER
DISCLOSURE SCHEDULE") corresponding to the Sections set forth below:

         3.01. ORGANIZATION AND QUALIFICATION. Seller is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Colorado. Each Subsidiary of Seller is a corporation duly


<PAGE>

organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. Seller and its Subsidiaries have all
requisite corporate power and authority to own, operate and lease its properties
and to carry on its business as it is now being conducted. Each of Seller and
its Subsidiaries is duly qualified as a foreign corporation, and is in good
standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification
necessary, other than in jurisdictions where the failure to be so qualified,
individually and in the aggregate, has not had and would not reasonably be
expected to have a Material Adverse Effect. Except as set forth in Section 3.01
of the Seller Disclosure Schedule, other than Seller's ownership interest in its
Subsidiaries, Seller has no direct or indirect equity or related interest in any
partnership, corporation, limited liability company, joint venture, business
association or other entity.

         3.02. ARTICLES OF ORGANIZATION; BYLAWS; AND STOCK TRANSFER RECORDS.
Seller has made available to Buyer prior to the date of this Agreement complete
and correct copies of (i) the Articles of Organization (or other charter
document) and By-laws of Seller and each of its Subsidiaries, (ii) shareholder
list of each of Seller's Subsidiaries and (iii) all stock certificates
representing any of the issued and outstanding capital stock of each of Seller's
Subsidiaries, and in each case such copies are or will be accurate and complete
as of the date of this Agreement or when furnished.

         3.03.    CAPITALIZATION OF SELLER.

         (a) On the date of this Agreement, the authorized capital stock of
Seller consists of (i) 15,000,000 shares of Seller Common Stock, of which
6,202,425 shares are issued and outstanding and (ii) 2,500,000 shares of
preferred stock, of which 15,000 shares have been designated Seller Preferred
Stock, of which 1,793 shares are issued and outstanding. Except for (i) Options
listed in the Seller Disclosure Schedule which were granted under the Seller
Equity Plans, (ii) the rights created pursuant to this Agreement, (iii) rights
created pursuant to the Warrants, (iv) rights created pursuant to the
Debentures, and (v) as set forth in Section 3.03 of Seller Disclosure Schedule,
there are no other options, warrants, calls, rights, commitments or agreements
of any character to which Seller is a party or by which it is bound obligating
Seller to issue, sell, deliver, repurchase or redeem or cause to be issued,
sold, delivered, repurchased or redeemed any shares of capital stock of, or
equity interests in, Seller. All outstanding shares are, and all shares subject
to issuance as aforesaid, upon issuance on the terms and conditions specified in
the instruments pursuant to which they are issuable, will be, duly authorized,
validly issued, fully paid and nonassessable and free of preemptive rights or
rights of first refusal. None of Seller or any of its Subsidiaries is required
to redeem, repurchase or otherwise acquire shares of capital stock of Seller or
any of its Subsidiaries. Seller has no stockholder rights plan or agreement in
force providing for the issuance to holders of shares of Seller Common Stock or
Seller Preferred Stock of rights to purchase or receive stock, cash or other
assets upon the acquisition or proposed acquisition of shares of Seller Common
Stock or Seller Preferred Stock by a Person (a "RIGHTS PLAN"), nor has Seller's
Board of Directors or stockholders ever adopted a Rights Plan.

         (b) All of Seller's Subsidiaries are listed in Exhibit 21.1 to Seller's
Annual Report on Form 10-KSB for the fiscal year ended March 31, 1999 (the "1999
10-KSB"). Except as set forth in the 1999 10-KSB or in the Seller Disclosure
Schedule, Seller owns all of the outstanding capital stock of its Subsidiaries
free and clear of any liens, security interests, pledges, agreements, claims,
charges or encumbrances of any nature whatsoever. Except as set forth in Section
3.03 of Seller Disclosure Schedule, there are no voting trusts or other
agreements or understandings to which Seller or any of its Subsidiaries is a
party or by which Seller or any of its Subsidiaries may be bound with respect to
the voting of the capital stock of Seller or any of Seller's Subsidiaries.
Except as set forth in Section 3.03 of Seller Disclosure Schedule, there are no
options, warrants, calls, rights, commitments, or agreements of any character to
which any of Seller's Subsidiaries is a party or by which any of Seller's
Subsidiaries is bound obligating such Subsidiary to issue, sell, deliver,
repurchase or redeem, or caused to be issued, sold, delivered, repurchased or
redeemed, any shares of capital stock of, or equity interests in, such
Subsidiary. All of the outstanding capital stock of each of Seller's
Subsidiaries is duly authorized, validly issued, fully paid and nonassessable
and issued free of preemptive rights or rights of first refusal.


<PAGE>

         3.04. CORPORATE POWER, AUTHORIZATION AND ENFORCEABILITY. Seller has all
requisite corporate power and authority to enter into this Agreement and to
perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by Seller, the
performance by Seller of its obligations hereunder and the consummation by
Seller of the transactions contemplated hereby have been duly and validly
authorized by Seller's Board of Directors and no other corporate action on the
part of Seller is necessary to authorize this Agreement or to consummate the
transactions contemplated hereby (other than, with respect to the Offer and the
Merger, the approval and adoption of this Agreement by holders of a majority of
the Seller Common Stock and, with respect to the Merger, the approval and
adoption of this Agreement by the holders of a majority of the Seller Preferred
Stock). This Agreement has been duly executed and delivered by Seller and is a
legal, valid and binding obligation of Seller, enforceable against Seller in
accordance with its terms. The affirmative vote of the holders of a majority of
the outstanding shares of Seller Common Stock and Seller Preferred Stock
entitled to vote thereon is the only vote of any class of capital stock of
Seller required by the CBCA, the Articles of Organization of Seller or the
Bylaws to adopt this Agreement and approve the Offer and the Merger.

         3.05.    NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

         (a) Assuming satisfaction of any applicable requirements referred to in
Section 3.05(b) below, and except as set forth in Section 3.05 of the Seller
Disclosure Schedule, the execution and delivery by Seller of this Agreement, the
compliance by Seller with the provisions hereof and the consummation by Seller
of the transactions contemplated hereby:

                  (A) will not conflict with or violate any statute, law,
         ordinance, rule, regulation, order, writ, judgment, award, injunction,
         decree or ruling applicable to Seller or any of its Subsidiaries or any
         of their properties, or conflict with, violate or result in any breach
         of or constitute a default (or an event which with notice or lapse of
         time or both would become a default) under, or give to others any
         rights of termination, amendment, cancellation or acceleration of, or
         the loss of a benefit under, or result in the creation of a lien,
         security interest, charge or encumbrance on any of the properties or
         assets of Seller or any of its Subsidiaries pursuant to (i) the
         Articles of Organization (or other charter document) or Bylaws of
         Seller or any of its Subsidiaries, or (ii) any contract, lease,
         agreement, note, bond, mortgage, indenture, deed of trust, or other
         instrument or obligation, or any license, authorization, permit,
         certificate or other franchise, other than such conflicts, violations,
         breaches, defaults, losses, rights of termination, amendment,
         cancellation or acceleration, liens, security interests, charges or
         encumbrances as to which requisite waivers have been obtained; and

                  (B) do not and will not result in any grant of rights to any
         other party under the Articles of Organization (or other charter
         document) or Bylaws of Seller or any of its Subsidiaries or restrict or
         impair the ability of the Buyer or any of its Subsidiaries to vote, or
         otherwise exercise the rights of a stockholder with respect to shares
         of Seller or any of its Subsidiaries that may be directly or indirectly
         acquired or controlled by them.

         (b) Other than in connection with or in compliance with the provisions
of the CBCA and the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), (i) Seller is not required to submit any notice, report, registration,
declaration or other filing with any foreign, federal, state or local
government, court, administrative agency or commission or other governmental
authority or instrumentality, domestic or foreign (collectively, "GOVERNMENTAL
ENTITIES"), in connection with the execution or delivery of this Agreement by
Seller or the performance by Seller of its obligations hereunder or the
consummation by Seller of the transactions contemplated by this Agreement and
(ii) no waiver, consent, approval, order or authorization of any Governmental
Entity is required to be obtained in connection with the execution or delivery
of this Agreement by Seller or the performance by Seller of its obligations
hereunder or the consummation by Seller of the transactions contemplated by this
Agreement, other than such notices, reports, registrations, declarations,
filings, waivers, consents, approvals, orders, or authorizations, the absence of
which would not, individually and in the


<PAGE>

aggregate, subject Seller or its Subsidiaries to any criminal penalties or
otherwise reasonably be expected to have a Material Adverse Effect.

         3.06. SEC REPORTS; FINANCIAL STATEMENTS. Seller has filed all required
reports, schedules, forms, statements and other documents with the Securities
and Exchange Commission (the "SEC") since March 31, 1994 (collectively, the "SEC
REPORTS"). Seller has delivered to Buyer copies of (a) the consolidated balance
sheets of Seller and its Subsidiaries as of March 31 for the fiscal years 1998
and 1999, and the related consolidated statements of operations and cash flows
for the fiscal years 1997 through 1999, inclusive, as reported in the Annual
Report of Seller on Form 10-KSB for the fiscal year ended March 31, 1999 filed
with the SEC under the Exchange Act, accompanied by the audit report of Ernst &
Young LLP, and (b) the unaudited consolidated balance sheet of Seller and its
Subsidiaries as of September 30, 1999, the related unaudited consolidated
statements of income and changes in stockholders' equity for the six (6) months
ended September 30, 1999 and September 30, 1998 and the related unaudited
consolidated statements of cash flows for the six (6) months ended September 30,
1999 and September 30, 1998, all as reported in the Seller's Quarterly Report on
Form 10-QSB for the quarter ended September 30, 1999 (the "SEPTEMBER 1999
10-QSB") filed with the SEC under the Exchange Act. The March 31, 1999
consolidated balance sheet (the "SELLER BALANCE SHEET") of Seller (including the
related notes, where applicable) and the other financial statements referred to
herein were prepared in accordance with generally accepted accounting principles
applied on a consistent basis throughout the periods involved ("GAAP") (except
as may be indicated in the notes or schedules thereto and except, in the case of
the unaudited interim statements, as may be permitted under Form 10-QSB of the
Exchange Act) and present fairly in all material respects the consolidated
financial position of Seller and its consolidated Subsidiaries as of the dates
thereof and the consolidated results of their operations and cash flows as of
the dates and for the fiscal periods indicated therein (subject, in the case of
unaudited interim financial statements, to normal year-end adjustments). The
books and records of Seller and its Subsidiaries have been, and are being,
maintained in accordance with GAAP and applicable legal and regulatory
requirements. Each SEC Report filed with the SEC complied in all material
respects with the then applicable requirements of the Exchange Act and the
Securities Act of 1933, as amended (the "SECURITIES ACT"), and the rules and
regulations of the SEC promulgated thereunder and did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Seller has filed all
documents and agreements which were required to be filed as exhibits to the SEC
Reports. None of Seller's Subsidiaries is required to file any statements or
reports with the SEC.

         3.07. NO DEFAULT. Neither Seller nor any of its Subsidiaries is in
default or violation (and no event has occurred which with or without notice,
the lapse of time or the happening or occurrence of any other event would
constitute a default or violation) of any term, condition or provision of (i)
its Articles of Organization (or other charter document) or Bylaws, or (ii) any
contract, lease, agreement, license, note, bond, mortgage, indenture, deed of
trust or other instrument or obligation to which Seller or any of its
Subsidiaries is a party or by which Seller or its Subsidiaries or any of their
properties or assets may be bound (nor to the knowledge of Seller is any other
party thereto in breach thereof or default thereunder), except, in each case,
for such violations, conflicts, breaches or defaults which either individually
or in the aggregate will not have a Material Adverse Effect.

         3.08. COMPLIANCE WITH LAW. Except as set forth in Section 3.08 of the
Seller Disclosure Schedule, each of Seller and its Subsidiaries is in
compliance, and has conducted its respective businesses so as to comply with,
all statutes, laws, ordinances, rules, regulations, permits and approvals
applicable to its operations, whether domestic or foreign, other than where such
noncompliance will not result in, or create the possibility of resulting in, a
material limitation on the conduct of the business of Seller, will not cause, or
create the possibility of causing, Seller or any of its Subsidiaries to incur
any financial penalty in excess of $20,000, and will not otherwise result, or
create the possibility of resulting in, any Material Adverse Effect. Except as
disclosed in the SEC Reports, as of the date hereof no investigation or review
by any Governmental Entity with respect to Seller, any of its Subsidiaries or
any property owned or leased by Seller or any of its Subsidiaries is pending or,
to the knowledge of Seller, threatened.


<PAGE>

         3.09. PERMITS. Seller and its Subsidiaries have all permits,
authorizations, licenses and franchises from Governmental Entities required to
conduct their business as now being conducted, except where the failure to have
any such permits, authorizations, licenses and franchises would not have a
Material Adverse Effect. Section 3.09 of the Seller Disclosure Schedule lists as
of the date of this Agreement all of Seller's licenses and permits
(collectively, the "LICENSES"). The Licenses are the only permits and licenses
required by Seller to operate its business as currently conducted. Seller is not
in material default with respect to any of the Licenses. The consummation of the
transactions contemplated by this Agreement will not cause any default,
cancellation or loss of a benefit under, or require any approval of a
Governmental Authority with respect to, any of the Licenses.

         3.10. ABSENCE OF CERTAIN CHANGES. Except as disclosed in the 1999
10-KSB, the September 1999 10-QSB, in Section 3.10 of the Seller Disclosure
Schedule, or incurred hereinafter in the ordinary course of business consistent
with past practice and with Section 5.01 hereof, since March 31, 1999, (i) the
business of each of Seller and its Subsidiaries has been conducted only in the
ordinary course consistent with past practices, (ii) there has not been any
change in the business, assets, financial condition or results of operations of
Seller and its Subsidiaries, (iii) there has not been any change in any policy
or practice followed by Seller nor its Subsidiaries in the ordinary course of
business except for changes which have not had and are not likely to have a
Material Adverse Effect, (iv) there has not been any material agreement,
contract or commitment entered into, or agreed to be entered into, except for
those in the ordinary course of business; (v) there has not been any increase in
or establishment of any bonus, insurance, severance (including severance after a
change in control), deferred compensation, pension, retirement, profit sharing,
life insurance or split dollar life insurance, retiree medical or life
insurance, or other employee benefit plan, or any other increase in the
compensation payable or to become payable to any officers or key employees of
Seller or its Subsidiaries, except with respect to cash compensation, in the
ordinary course of business consistent with past practice; (vi) there has not
been any change in any of the accounting methods or practices of Seller and its
Subsidiaries other than changes required by applicable law or applicable
accounting policies; and (viii) neither Seller nor its Subsidiaries has
declared, paid or set aside for payment any dividend or other distribution in
respect of its capital stock or redeemed, purchased or otherwise acquired,
directly or indirectly, any shares of capital stock or other securities of
Seller or any Subsidiary.

         3.11. NO UNDISCLOSED LIABILITIES. Except for liabilities and
obligations incurred since March 31, 1999 in the ordinary course of business,
incurred in connection with this Agreement or identified in Section 3.11 of the
Seller Disclosure Schedule, neither Seller nor any of its Subsidiaries has any
liabilities or obligations of any nature whatsoever (whether absolute, accrued,
fixed, contingent, liquidated, unliquidated or otherwise), required by generally
accepted accounting principles to be recognized or disclosed on a consolidated
balance sheet of Seller and its Subsidiaries or in the notes thereto, other than
those recognized or disclosed in the Seller Balance Sheet or disclosed in the
1999 10-KSB or the September 1999 10-QSB.

         3.12. LITIGATION. Except as set forth in the 1999 10-KSB or the
September 1999 10-QSB, there is no action, suit, investigation or proceeding
pending against, or to the knowledge of Seller, threatened against or affecting,
Seller or any of its Subsidiaries or any of their respective properties as to
which there is a reasonable possibility of an adverse determination and which if
determined adversely to Seller could be expected to have a Material Adverse
Effect and there is no judgment, decree, writ, injunction, award, ruling or
order of any Governmental Entity or arbitrator outstanding against Seller or any
of its Subsidiaries having, or which, insofar as can reasonably be foreseen, in
the future would have, a Material Adverse Effect. Section 3.12 of the Seller
Disclosure Schedule includes a list of all litigation pending or threatened
against Seller as of the date of this Agreement. Seller has made available to
Buyer correct and complete copies of all correspondence prepared by its counsel
for Seller's auditors in connection with the last completed audit of Seller's
financial statements and any such correspondence since the date of the last such
audit. As of the date of this Agreement, there are no actions, suits or
proceedings pending or, to the knowledge of Seller, threatened against Seller
arising out of or in any way related to this Agreement, the Offer, the Merger or
any of the transactions contemplated hereby or thereby.

         3.13.    ERISA.

         (a) Section 3.13 of the Seller Disclosure Schedule lists each "employee
benefit plan," as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), and all other written or oral plans
or agreements involving direct or indirect compensation (including any
employment agreements entered into between Seller or any of its Subsidiaries and
any employee or former employee of Seller or any of its Subsidiaries, but
excluding worker's compensation, unemployment compensation and other
government-mandated programs) currently or previously maintained, contributed to
or entered into by Seller or any of its Subsidiaries or any ERISA Affiliate
thereof for the benefit of any employee or former employee of or current or
former service provider to Seller or any of its Subsidiaries under which Seller
or any of its Subsidiaries or any ERISA Affiliate thereof has or may have any
present or future obligation or liability (collectively, the "SELLER EMPLOYEE
PLANS"). For purposes of this Section 3.13, "ERISA AFFILIATE" shall mean any
entity which is a member of (i) a "controlled group of corporations," as defined
in Section 414(b) of the Internal Revenue Code of 1986, as amended (the "CODE"),
(ii) a group of entities under "common control," as defined in Section 414(c) of
the Code or (iii) an "affiliated service group," as defined in Section 414(m) of
the Code or treasury regulations promulgated under Section 414(o) of the Code,
any of which includes Seller or any of its Subsidiaries. Section 3.13 of Seller
Disclosure Schedule identifies the only Seller Employee Plans which individually
or collectively would constitute an "employee pension benefit plan," as defined
in Section 3(2) of ERISA (collectively, the "SELLER PENSION PLANS").

         (b) No Seller Pension Plan is subject to Title IV of ERISA, Part 3 of
Title I of ERISA or Section 412 of the Code. No Seller Pension Plan constitutes
or has since the enactment of ERISA constituted a "multiemployer plan," as
defined in Section 3(37) of ERISA. Nothing done or omitted to be done and no
transaction or holding of any asset under or in connection with any Seller
Employee Plan has or is likely to make Seller or any of its Subsidiaries or any
officer or director thereof subject to any material liability under Title I of
ERISA or liable for any material tax pursuant to Section 4975 of the Code.

         (c) Each Seller Pension Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date. Each trust forming a part of a Seller Pension
Plan is exempt from tax pursuant to Section 501(a) of the Code. Each Seller
Employee Plan has been maintained in compliance with its terms and with the
applicable requirements of ERISA and the Code.

         (d) Each employment, severance or other similar contract, arrangement
or policy and each plan or arrangement (written or oral) providing for insurance
coverage (including any self-insured arrangements), vacation benefits, severance
or severance-type benefits, disability benefits, death benefits, hospitalization
benefits, retirement benefits, deferred compensation, profit-sharing, bonuses,
stock options, stock purchase, phantom stock, stock appreciation or other forms
of incentive compensation or post-retirement insurance, compensation or benefits
which (i) is not a Seller Employee Plan, (ii) is entered into, maintained or
contributed to, as the case may be, by Seller or any of its Subsidiaries, and
(iii) covers any employee or former employee of or other current or former
service provider to Seller or any of its Subsidiaries, is herein referred to as
a "SELLER BENEFIT ARRANGEMENT" and collectively as the "SELLER BENEFIT
ARRANGEMENTS." All Seller Benefit Arrangements are listed in Section 3.13 of the
Seller Disclosure Schedule. Each Seller Benefit Arrangement has been maintained
in compliance with its terms and with the requirements prescribed by any and all
statutes (including but not limited to the Code), orders, rules and regulations
which are applicable to such Seller Benefit Arrangements.

         (e) There has been no amendment to, written interpretation or
announcement (whether or not written) by Seller or any of its Subsidiaries
relating to, or change in employee participation or coverage under, any Seller
Employee Plan or Seller Benefit Arrangement which would increase the expense of
maintaining such Seller Employee Plan or Seller Benefit Arrangement above the
level of the expense incurred in respect thereof for the fiscal year ended March
31, 1999.


<PAGE>

         (f) The Seller has complied with the requirements of Section 4980B of
the Code with respect to any "qualifying event" (as defined in Section
4980B(f)(3) of the Code) occurring prior to and including the Closing Date,
except where failure to be in compliance individually and in the aggregate has
not had and would not reasonably be expected to have a Material Adverse Effect
and, to Seller's knowledge, no tax payable on account of Section 4980B of the
Code has been incurred with respect to any current or former employees of Seller
or any of its Subsidiaries.

         (g) There is no term of any Seller Employee Plan or Seller Benefit
Arrangement covering a "disqualified individual" (as defined in Section 280G(c)
of the Code), or of any contract, instrument, agreement or arrangement with any
such disqualified individual, that individually or collectively could result in
a disallowance of the deduction for any "excess parachute payment" (as defined
in Section 280G(b)(i) of the Code) or the imposition of the excise tax provided
in Section 4999 of the Code. The consummation of the transactions contemplated
by this Agreement will not result in any "excess parachute payment" or the
imposition of any such excise tax.

         (h) Seller has heretofore delivered or made available to Buyer copies
of all of Seller Employee Plans, Seller Pension Plans and Seller Benefit
Arrangements listed in Section 3.13 of Seller Disclosure Schedule.

         (i) There is no pending or, to Seller's knowledge, threatened legal
action, proceeding or investigation, other than routine claims for benefits,
concerning any Seller Employee Plan, Seller Pension Plan or Seller Benefit
Arrangement or, to the knowledge of Seller any fiduciary or service provider
thereof and, to the knowledge of Seller, there is no basis for any such legal
action or proceeding.

         (j) No Seller Employee Plan or Seller Benefit Arrangement provides
health, life or other similar welfare coverages after termination of employment
except to the extent required by applicable state insurance laws and Title I,
Part 6 of ERISA.

         (k) With respect to each Seller Employee Plan, Seller Pension Plan or
Seller Benefit Arrangement for which a separate fund of assets is or is required
to be maintained, full payment has been made of all amounts required of Seller
and its Subsidiaries and ERISA Affiliates under the terms of each such Plan or
Arrangement or applicable law, through the Closing Date.

         3.14. LABOR MATTERS. There is no labor strike, dispute, slowdown,
stoppage or lockout actually pending, or threatened against Seller or any
Subsidiary. Neither Seller nor any Subsidiary is a party to or bound by any
collective bargaining agreement with any labor organization applicable to
employees of Seller or any Subsidiary. Neither Seller nor any Subsidiary has
experienced any material work stoppage or other material labor difficulty during
the two-year period ending on the date hereof.

         3.15.    TAX RETURNS AND REPORTS.

         (a) Seller and its Subsidiaries have timely filed in correct form with
the appropriate taxing authorities all federal, state, county, local and foreign
returns, estimates, information statements, reports and other documents in
respect of Taxes (as defined in Article VIII) required to be filed by Seller and
its Subsidiaries. All amounts shown due on such returns have been timely paid as
required by law.

         (b) No assessment that has not been settled or otherwise resolved has
been made with respect to Taxes not shown on the Tax returns, other than such
additional Taxes as are being contested in good faith or which if determined
adversely to Seller would not have a Material Adverse Effect. There are no
material disputes pending or written claims asserted for Taxes or assessments
upon Seller or any of its Subsidiaries, nor has Seller or any of its
Subsidiaries been requested to give any currently effective waivers extending
the statutory period of limitation applicable to any Federal, state, county,
foreign or local income tax return for any period. No deficiency in Taxes or
other proposed adjustment that has not been settled or otherwise resolved has

<PAGE>

been asserted in writing by any taxing authority against any of Seller or its
Subsidiaries. No Tax return of Seller or any of its Subsidiaries is now under
examination by any applicable taxing authority. There are no material liens for
Taxes (other than current Taxes not yet due and payable) on any of the assets of
Seller or any of its Subsidiaries, except for such liens for Taxes that would
not have a Material Adverse Effect. During the past five years, no jurisdiction
has made any written claim or allegation, or made any written inquiry pursuant
to such a written claim or allegation, that Seller or any of its Subsidiaries is
required to file Tax returns in such jurisdiction for any Tax for which Seller
or the applicable Subsidiary does not presently filed Tax returns in such
jurisdiction.

         (c) Adequate provision has been made on the Seller Balance Sheet for
all Taxes of Seller and its Subsidiaries in respect of all periods through the
date hereof.

         (d) As of the date of this Agreement, Seller has no ruling requests
currently pending with the Internal Revenue Service.

         (e) Except as set forth in the SEC Reports, neither Seller nor any of
its Subsidiaries is a party to (or obligated under) any Tax allocation, tax
sharing or tax indemnity agreement which has as a party any Person other than
Seller or its Subsidiaries.

         (f) Seller and its Subsidiaries have withheld and paid all Taxes
required to have been withheld and paid in connection with amounts paid or owing
to any employee, consultant, independent contractor, creditor, stockholder or
other party.

         3.16. SELLER DEBT. Section 3.16 of the Seller Disclosure Schedule lists
all outstanding Indebtedness of Seller and each Subsidiary as of the date
hereof, except for individual items of indebtedness the principal amount of
which do not exceed $25,000. Section 3.16 of the Seller Disclosure Schedule sets
forth the amount of principal and unpaid interest outstanding under each
instrument evidencing Indebtedness of Seller or each Subsidiary, if any, that
will accelerate or become due or result in a right on the part of the holder of
such indebtedness (with or without due notice or lapse of time) to require
prepayment, redemption or repurchase as a result of the execution of this
Agreement or the consummation of the transactions contemplated hereby.

         3.17.    TRADEMARKS, PATENTS AND COPYRIGHTS.

         (a) Section 3.17 of the Seller Disclosure Schedule contains a true and
complete list of Seller Intellectual Property and includes details of all due
dates for further filings, maintenance, payments or other actions falling due
within twelve (12) months of the Closing Date. All of Seller's patents, patent
applications, registered trademarks, and trademark applications, and registered
copyrights remain in good standing with all fees and filings due as of the
Closing Date duly made and the due dates specified in the Seller Disclosure
Schedule are accurate and complete.

         (b) The Seller Intellectual Property consists solely of items and
rights which are: (i) owned by Seller; or (ii) rightfully used by Seller
pursuant to a valid license ("SELLER LICENSED INTELLECTUAL PROPERTY"), the
parties and date of each such license agreement and each material agreement in
which Seller is the licensor or owner of the subject rights in the agreement
being set forth on Section 3.17(b) of the Seller Disclosure Schedule. Seller has
all rights in Seller Intellectual Property necessary to carry out Seller's
current activities (and had all rights necessary to carry out its former
activities at the time such activities were being conducted), including without
limitation, to the extent required to carry out such activities, rights to make,
use, reproduce, modify, adopt, create derivative works based on, translate,
distribute (directly and indirectly), transmit, display and perform publicly,
license, rent and lease and, other than with respect to the Seller Licensed
Intellectual Property, assign and sell, the Seller Intellectual Property.

         (c) The reproduction, manufacturing, distribution, licensing,
sublicensing or sale of any Seller Intellectual Property, now used or offered or
proposed for use, licensing or sale by Seller does not infringe on


<PAGE>

any patent, copyright, trademark, service mark, trade name, trade dress, firm
name, Internet domain name, logo, trade dress, of any person and does not
constitute a misappropriation of any trade secret. No claims (i) challenging the
validity, effectiveness or ownership by Seller of any of the Seller Intellectual
Property, or (ii) to the effect that the use, distribution, licensing,
sublicensing or sale of the Seller Intellectual Property as now used or offered
or proposed for use, licensing, sublicensing or sale by Seller infringes or will
infringe on any intellectual property or other proprietary right of any person
have been asserted or, to the knowledge of Seller, are threatened by any person
or have been made or threatened by any person against the Seller's distributors.
To the knowledge of Seller, there is no unauthorized use, infringement or
misappropriation of any of the Seller Intellectual Property by any third party,
employee or former employee.

         (d) All Seller Intellectual Property has been solely developed by full
time employees within the scope of his or her employment with the Seller or
within the scope of his or her employment with companies acquired by Seller
prior to the date hereof. All employee contribution or participation in the
conception and development of the Seller Intellectual Property on behalf of
Seller constitutes work prepared by an employee within the scope of his or her
employment in accordance with applicable federal and state law that has accorded
Seller ownership of all tangible and intangible property thereby arising.

         (e) Seller is not, nor as a result of the execution or delivery of this
Agreement, or performance of Seller's obligations hereunder, will Seller be, in
violation of any material license, sublicense, agreement or instrument to which
Seller is a party or otherwise bound, nor will execution or delivery of this
Agreement, or performance of Seller's obligations hereunder, cause the
diminution, termination or forfeiture of any material Seller Intellectual
Property.

         (f) Section 3.17(f) of the Seller Disclosure Schedule contains a true
and complete list of all of Seller's internally-developed software programs
("SELLER SOFTWARE PROGRAMS"). Seller owns full and unencumbered right and good,
valid and marketable title to such Seller Software Programs and all Seller
Intellectual Property free and clear of all mortgages, pledges, liens, security
interests, conditional sales agreements or encumbrances.

         (g) The Seller Software Programs (i) have been designed to ensure year
2000 compatibility, which includes, but is not limited to, being able to provide
specific dates and calculate spans of dates within and between twentieth century
and twenty-first century, prior to, including and following January 1, 2000;
(ii) operate and will operate in accordance with their specifications and
correctly process day and date calculations for dates prior and up to December
31, 1999, and on and after January 1, 2000, prior to, during and after the
calendar year 2000; and (iii) shall not end abnormally or provide invalid or
incorrect results as a result of date data, specifically including date data
which represents or references different centuries or more than one century.

         3.18. MATERIAL AGREEMENTS. Except as set forth in the 1999 10-KSB and
as listed in Section 3.18 of the Seller Disclosure Schedule, except for this
Agreement and the agreements specifically referred to herein, neither Seller nor
any of its Subsidiaries is a party to or bound by any of the following
agreements (with the following agreements, and the agreements included as
exhibits to the SEC Reports, collectively referred to as the "MATERIAL
AGREEMENTS"):

         (a) any contract or agreement or amendment thereto that would be
required to be filed as an exhibit to a registration statement on Form S-1 filed
by Seller as of the date hereof;

         (b) any confidentiality agreement, non-competition agreement or other
contract or agreement that contains covenants limiting Seller's or any of its
Subsidiaries' freedom to compete in any line of business or in any location or
with any Person; and


<PAGE>

         (c) any loan agreement, indenture, note, bond, debenture or any other
document or agreement evidencing a capitalized lease obligation or other
Indebtedness (as defined in Article VIII) to any Person, other than any
Indebtedness in a principal amount less than $25,000 individually or $100,000 in
the aggregate.

         Seller has delivered to Buyer a correct and complete copy of each
Material Agreement and a written summary setting forth the terms and conditions
of each oral agreement, if any, referred to in the Seller Disclosure Schedule.
Each such Material Agreement constitutes the legal, valid and binding obligation
of Seller or a Subsidiary, as the case may, and to the knowledge of Seller, the
other party thereto, enforceable against such parties in accordance with the
terms thereof (except as enforcement may be limited by general principles of
equity whether applied in a court of law or equity and by bankruptcy, insolvency
and similar laws affecting creditors' rights and remedies generally). None of
Seller or any of its Subsidiaries, as the case may be, is in default under, or
with the giving of notice or the lapse of time, or both, would be in default
under, any of the material terms or conditions of any Material Agreement. To the
knowledge of Seller, there has occurred no material default or event which, with
the giving of notice or the lapse of time, or both, would constitute a material
default by any other party to any Material Agreement.

         3.19. INSURANCE. Seller and each Subsidiary is presently insured, and
during each of the past five calendar years has been insured, against such risks
as companies engaged in a similar business would, in accordance with good
business practice, customarily be insured. The policies of fire, theft,
liability and other insurance maintained with respect to the assets or
businesses of Seller and its Subsidiaries provide reasonably adequate coverage
against loss. Seller has heretofore furnished to Buyer a complete and correct
list as of the date hereof of all insurance policies maintained by Seller or its
Subsidiaries, and has made available to Buyer complete and correct copies of all
such policies, together with all riders and amendments thereto. All such
policies are in full force and effect and all premiums due thereon have been
paid to the date hereof. Seller and its Subsidiaries have complied in all
material respects with the terms of such policies.

         3.20. PROPERTIES. Except as set forth in Section 3.20 of the Seller
Disclosure Schedule, neither Seller nor any or its Subsidiaries owns any real
property. Seller and its Subsidiaries have good and valid title, free and clear
of all Encumbrances to all of their material properties and assets, whether
tangible or intangible, real, personal or mixed, reflected in the 1999 10-KSB as
being owned by Seller and its Subsidiaries as of the date thereof, other than
(i) any properties or assets that have been sold or otherwise disposed of in the
ordinary course of business since the date of the Seller Balance Sheet, (ii)
liens disclosed in the notes to the Seller Balance Sheet and (iii) liens arising
in the ordinary course of business after the date of the Seller Balance Sheet.
All buildings, and all fixtures, equipment and other property and assets that
are material to its business on a consolidated basis, held under leases or
sub-leases by Seller or any Subsidiary are held under valid instruments
enforceable in accordance with their respective terms, subject to applicable
laws of bankruptcy, insolvency or similar laws relating to creditors' rights
generally and to general principles of equity (whether applied in a proceeding
in law or equity). Substantially all of Seller's and its Subsidiaries' equipment
in regular use has been reasonably maintained and is in serviceable condition,
reasonable wear and tear excepted.

         3.21. LEASES. Section 3.21 of the Seller Disclosure Schedule lists all
outstanding leases, both capital and operating, or licenses, pursuant to which
Seller or any of its Subsidiaries has (i) obtained the right to use or occupy
any real or tangible personal property under arrangements where the remaining
obligation is more than $25,000, inclusive of any renewal rights or (ii) granted
to any other Person the right to use any material item of machinery, equipment,
furniture, vehicle or other personal property of Seller or any of its
Subsidiaries having an original cost of $25,000 or more.

         3.22. BUSINESS ACTIVITY RESTRICTION. Except as set forth in Section
3.22 of the Seller Disclosure Schedule, there is no non-competition or other
similar agreement, commitment, judgment, injunction, order or decree to which
Seller or any Subsidiary is a party or subject to that has or could reasonably
be expected to have the effect of prohibiting or impairing the conduct of
business by Seller. Seller has not entered into any agreement under which Seller
is restricted from selling, licensing or otherwise distributing any of its
technology


<PAGE>

or products to, or providing services to, customers or potential customers or
any class of customers, in any geographic area, during any period of time or in
any segment of the market or line of business.

         3.23.    ACCOUNTS RECEIVABLE; INVENTORY.

         (a) Except as specifically set forth in Section 3.23 of the Seller
Disclosure Schedule, hereto, all accounts and notes receivable reflected in the
Seller Balance Sheet, and all accounts and notes receivable arising subsequent
to the date of the Seller Balance Sheet, have arisen in the ordinary course of
business, represent valid obligations to Seller or a Subsidiary and, subject
only to an amount of bad debts reasonable in the industry and not materially
different than Seller's past experience, have been collected or are collectible
in the aggregate recorded amounts thereof in accordance with their terms.

         (b) The inventories (and any reserves established with respect thereto)
of Seller and its Subsidiaries as of March 31, 1999 are described in Section
3.23(b) of the Seller Disclosure Schedule. All such inventories (net of any such
reserves) are properly reflected on the Seller Balance Sheet in accordance with
GAAP and, to the best knowledge of Seller, are of such quality as to be useable
and saleable in the ordinary course of business (subject, in the case of
work-in-process inventory, to completion in the ordinary course of business).

         3.24. CUSTOMERS AND SUPPLIERS. Neither Seller's nor any of its
Subsidiaries' customers which individually accounted for more than 5% of
Seller's or such Subsidiary's gross revenues during the 12-month period
preceding the date hereof has terminated or threatened or indicated an intention
to terminate any agreement with Seller or such Subsidiary. Except as set forth
in Section 3.24 of the Seller Disclosure Schedule, as of the date hereof, no
material supplier of Seller or any of its Subsidiaries has notified Seller in
writing that it will stop, or decrease the rate of, supplying materials,
products or services to Seller or such Subsidiary.

         3.25. YEAR 2000 COMPLIANCE. The only "mission-critical" computer
systems (as such term is commonly used in regulations and trade organization
guidelines with respect to the Year 2000 Problem (as defined below)) owned or
utilized by Seller and its Subsidiaries in their businesses are set forth in
Section 3.25 of the Disclosure Schedule (the "SELLER MISSION CRITICAL SYSTEMS").
Seller and its Subsidiaries have taken all steps necessary to ensure that all of
such Seller Mission Critical Systems will not, or each of Seller and its
Subsidiaries has received written assurances from the applicable third-party
service providers with respect to each Seller Mission Critical System that each
of such Seller Mission Critical Systems will not, contain any deficiencies
relating generally to formatting for entering dates (commonly referred to and
referred herein as the "YEAR 2000 PROBLEM") and each Seller Mission Critical
System is in compliance with all regulations and trade organization guidelines
concerning the Year 2000 Problem. To the knowledge of Seller, all of Seller's
and its Subsidiaries' other computer systems ("NON-MISSION CRITICAL SYSTEMS"),
third party service and equipment providers are in compliance with all
regulations and trade organization guidelines concerning the Year 2000 Problem,
except where the failure to be compliant would not result in any Material
Adverse Effect. None of Seller or any Subsidiary is aware of any inability on
the part of any customer or service provider with which Seller or any Subsidiary
transacts business to timely remedy any deficiencies of its own in respect of
the Year 2000 Problem.

         3.26. ENVIRONMENTAL MATTERS. Except as would not reasonably be
expected to have a Material Adverse Effect, (a) Seller and each Subsidiary
are in compliance with all applicable Environmental Laws, (b) neither Seller
nor any Subsidiary has received any written notice with respect to the
business of, or any property owned or leased by, Seller or any Subsidiary
from any governmental entity or third party alleging that Seller or any
Seller Subsidiary is not in compliance with any Environmental Law, and (c)
there has been no "release" of a "hazardous substance", as those terms are
defined in the Comprehensive Environmental Response, Compensation, and
Liability Act, 42 U.S.C. Section 9601 ET SEQ., in excess of a reportable
quantity on any real property owned by Seller or any Subsidiary that is used
for the business of Seller or any Subsidiary.

         3.27. PRIOR ACQUISITIONS AND DISPOSITIONS. Except as set forth in the
1999 10-KSB or in Section 3.27 of the Seller Disclosure Schedule, no claims,
amounts owed, liabilities (contingent or otherwise), encumbrances,


<PAGE>

legal proceedings or any other obligations of any kind are due or were incurred
or outstanding in connection with any acquisitions or dispositions made by
Seller or any of its Subsidiaries prior to the date of this Agreement.

         3.28. ABSENCE OF CERTAIN BUSINESS PRACTICES. No employee, consultant,
agent or other representative of Seller or any of its Subsidiaries has directly
or indirectly within the past five years given or agreed to give any gift or
similar benefit to any customer, supplier, governmental employee or other Person
who is or may be in a position to help or hinder the business of Seller or any
of its Subsidiaries in connection with any actual or proposed transaction which
(a) would reasonably be expected to subject Seller or any of its Subsidiaries to
any damage or penalty in any civil, criminal or governmental litigation or
proceeding, (b) if not given in the past, would reasonably be expected to have
had a Material Adverse Effect, or (c) if not continued in the future, would
reasonably be expected to have a Material Adverse Effect. Without limiting the
generality of the foregoing, Seller has not committed, been charged with or to
the knowledge of Seller been under investigation with respect to, nor does there
exist, any violation by Seller of the Foreign Corrupt Practices Act, as amended
(the "FCPA").

         3.29. TAKEOVER LAWS. No "fair price," "moratorium," "control share
acquisition" or other similar anti-takeover statute or regulation enacted under
state or federal laws in the United States including, without limitation,
applicable to Seller or any of Seller Subsidiaries is applicable to the
execution, delivery and performance of this Agreement, the Seller Option
Agreement or the Stockholder Agreements or the consummation of the Offer or the
Merger.

         3.30. OPINION OF FINANCIAL ADVISOR. Seller has received the opinion of
Seller's Financial Advisor, as of the date of this Agreement, to the effect that
the Merger Consideration is fair, from a financial point of view, to Seller's
stockholders.

         3.31. DISCLOSURE. To Seller's knowledge, as of the date of this
Agreement, no representation or warranty by Seller in this Agreement contains
any untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements contained
therein, in light of the circumstances under which they were made, not false or
misleading.

         3.32. BROKERS AND FINDERS. Seller has furnished to Buyer or its counsel
a true and complete copy of that certain letter agreement (the "WASSERSTEIN
ENGAGEMENT LETTER") between Seller and Wasserstein Perella & Co., Inc. (the
"SELLER'S FINANCIAL ADVISOR"), such letter agreement being the only agreement
pursuant to which such firm would be entitled to any payment relating to the
transactions contemplated hereunder. No broker, finder or investment banker
other than Seller's Financial Advisor is entitled to any brokerage, finder's or
other fee or commission in connection with the transactions contemplated by this
Agreement based upon arrangements made by or on behalf of Seller or any of its
Subsidiaries.

<PAGE>


         5.03.    PROXY STATEMENT.

         (a) Promptly after execution and delivery of this Agreement, Seller
shall prepare and shall file with the SEC as soon as is reasonably practicable a
preliminary Proxy Statement, together with a form of proxy, with respect to the
Seller Special Meeting and shall use all reasonable efforts to have the Proxy
Statement and form of proxy cleared by the SEC as promptly as practicable, and
promptly after request by Buyer shall mail the definitive Proxy Statement and
form of proxy to stockholders of Seller. Subject to its fiduciary duties under
applicable law, the Proxy Statement shall contain the recommendation of the
Board of Directors that the stockholders of Seller vote to adopt and approve the
Offer, the Merger and this Agreement. The term "Proxy Statement" shall mean such
proxy or information statement at the time it initially is mailed to Seller's
stockholders and all amendments or supplements thereto, if any, similarly filed
and mailed.

         (b) Buyer will provide Seller with all information concerning Buyer (or
its Affiliates) required to be included in, or otherwise reasonably requested by
Seller in connection with the preparation of, the Proxy Statement. The
information provided and to be provided by Buyer and Seller, respectively, for
use in the Proxy Statement shall, on the date the Proxy Statement is first
mailed to Seller's stockholders and on the date of the Seller Special Meeting
(as hereinafter defined), not contain an untrue statement of a material fact or

light of the circumstances under which it was provided, not misleading, and
Seller and Buyer each agree to correct any information provided by it for use in
the Proxy Statement which shall have become false or misleading in any material
respect. The Proxy Statement shall comply as to form in all material respects
with all applicable requirements of federal securities laws.

         5.04.    MEETING OF STOCKHOLDERS OF SELLER.

         (a) Seller shall take all action necessary, in accordance with the CBCA
and its Articles of Incorporation, to cause only proposals one and two set forth
in Seller's definitive proxy statement (the "ANNUAL MEETING PROXY STATEMENT")
filed with the SEC on November 2, 1999, to be voted on by Seller's stockholders
at the annual meeting of Seller's stockholders currently scheduled for December
2, 1999 (the "ANNUAL MEETING"). Seller shall take all action necessary to cause
proposals three, four and five set forth in the Annual Meeting Proxy Statement
not to be voted on by the stockholders of Seller at the Annual Meeting,
including causing all proxies held by management of Seller to be voted in favor
of adjourning the Annual Meeting so that no such vote is taken on such matters
at such meeting.

         (b) If required under the CBCA and Seller's Articles of Incorporation,
Seller shall, as soon as practicable following the expiration of the Offer, duly
call, give notice of, convene and hold a meeting of its stockholders (the
"SELLER SPECIAL MEETING") to consider and vote upon this Agreement, the Offer
and the Merger and shall, through its Board of Directors, recommend to its
stockholders the approval and adoption of the Offer, this Agreement, the Merger
and the other transactions contemplated hereby. Without limiting the generality
of the foregoing but subject to its rights to terminate this Agreement pursuant
to Section 7.01(d), Seller agrees that its obligations pursuant to the second
sentence of this Section 5.04 shall not be affected by the commencement, public
proposal, public disclosure or communication to Seller of any Acquisition
Proposal. Notwithstanding the foregoing, if Buyer shall acquire at least 90% of
the outstanding shares of Seller Common Stock in the Offer, the parties shall
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
Seller Special Meeting in accordance with the CBCA. Buyer agrees to cause all
shares of Seller Common Stock purchased pursuant to the Offer to be voted in
favor of the Merger, this Agreement and the transactions contemplated hereby.

         5.05.    NO SOLICITATION BY SELLER.

         (a) Except as provided in Section 5.05(b), Seller agrees that, from the
date of this Agreement until the earlier of the Effective Time or the
termination of this Agreement pursuant to Section 7.01, Seller shall not, nor
shall it permit any of its Subsidiaries to, nor shall it authorize or permit any
of its directors, officers or employees or any representative retained by it
(including Seller's Financial Advisor) or any of its Subsidiaries


<PAGE>

to, directly or indirectly through another Person, (i) solicit, initiate,
entertain or encourage (including by way of furnishing non-public information)
any inquiries or the making of an Acquisition Proposal, or (ii) participate in
any discussions or negotiations regarding any Acquisition Proposal; PROVIDED,
HOWEVER, that if, at any time, the Board of Directors of Seller determines in
good faith, after consultation with and receipt of advice from outside counsel,
that it is necessary to do so in order to act in a manner consistent with its
fiduciary duties to Seller's stockholders under applicable law, Seller may, in
response to a Superior Proposal (as defined below) and subject to delivering a
Seller Notice (as defined in paragraph (c) below) and compliance with the other
provisions of paragraph (c) below, following delivery of Seller Notice (x)
furnish information with respect to Seller and its Subsidiaries to any Person
making such Acquisition Proposal pursuant to a confidentiality agreement entered
into between such Person and Seller with terms no less favorable to Seller than
those contained in the Confidentiality Agreement and (y) participate in
discussions or negotiations regarding such Acquisition Proposal. For purposes of
this Agreement, an "Acquisition Proposal" means any inquiry, proposal or offer
from any Person (i) relating to any direct or indirect acquisition or purchase
of (A) a business that constitutes 15% or more of the net revenues, net income
or the assets of Seller and its Subsidiaries, taken as a whole, (B) 20% or more
of any class of equity securities of Seller or (C) any material equity interest
in any Subsidiary of Seller (i.e., in excess of 20% of the outstanding capital
stock of such Subsidiary), (ii) relating to any tender offer or exchange offer
that if consummated would result in any Person beneficially owning 20% or more
of any class of equity securities of Seller or any material equity interest in
any of its Subsidiaries, or (iii) relating to any merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving Seller or any of its Subsidiaries, in each case, other
than the transactions contemplated by this Agreement. Immediately following the
execution and delivery of this Agreement by the parties hereto, Seller will
cease and cause to be terminated any existing activities, discussions or
negotiations with any parties conducted with respect to the foregoing. Promptly
following the execution of this Agreement by the parties hereto, Seller will
request each Person that has, prior to the date of this Agreement, executed a
confidentiality agreement in connection with its consideration of an Acquisition
Proposal to return or destroy all confidential information heretofore furnished
to such Person by or on behalf of Seller or any of its Subsidiaries.

         (b) Except as expressly permitted by this Section 5.05, the Board of
Directors of Seller shall not (i) withdraw or modify, or propose publicly to
withdraw or modify, in a manner adverse to Buyer, the approval or recommendation
by such Board of Directors of the Merger, the Offer or this Agreement, (ii)
approve or recommend, or propose publicly to approve or recommend, any
Acquisition Proposal, or (iii) cause Seller to enter into any letter of intent,
agreement in principle, acquisition agreement or other similar agreement (each,
a "SELLER ACQUISITION AGREEMENT") related to any Acquisition Proposal, other
than any such agreement entered into concurrently with a termination pursuant to
the next sentence to facilitate such action. Notwithstanding the foregoing, if
at any time the Board of Directors of Seller determines in good faith, after
consultation with and receipt of advice from outside counsel, that it is
necessary to do so in order to act in a manner consistent with its fiduciary
duties to Seller's stockholders under applicable law, subject to compliance with
paragraph (c) below, the Board of Directors of Seller may, in response to a
Superior Proposal which was not solicited by Seller and which did not otherwise
result from a breach of this Section 5.05 (subject to this and the following
sentences) terminate this Agreement (and concurrently with or after such
termination, if it so chooses, cause Seller to enter into any Acquisition
Agreement with respect to any Superior Proposal) but only at a time that is at
least after the third business day after delivery of a Seller Notice. For
purposes of this Agreement, a "Superior Proposal" means any proposal made by a
third party to acquire, directly or indirectly, including pursuant to a tender
offer, exchange offer, merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction, for
consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of Seller Common Stock then outstanding or
all or substantially all the assets of Seller which (i) the Board of Directors
of Seller determines in good faith is reasonably likely to be consummated,
taking into account the Person making the proposal and all legal, financial and
regulatory aspects of the proposal, including any break-up fees, expense
reimbursement provisions and conditions to consummation, and (ii) the Board of
Directors determines in good faith (after consultation with and based upon the
advice of its outside financial advisors) would, if consummated, provide greater
value to Seller's stockholders than the transactions contemplated by this
Agreement.


<PAGE>

         (c) In addition to the obligations of Seller as set forth in paragraphs
(a) and (b) of this Section 5.05, Seller shall advise the Buyer orally and in
writing of any request for non-public information, any Acquisition Proposal,
including all of the material proposed terms of such Acquisition Proposal, the
identity of the third party, or any decision by Seller to take any of the
actions permitted in clauses (x) or (y) of paragraph (a) above (with any such
notice referred to as a "SELLER NOTICE"). Any such Seller Notice will be
delivered promptly after (and in no event later than 24 hours after) receipt of
any request for non-public information or of any Acquisition Proposal and prior
to Seller taking any of the actions permitted in clauses (x) or (y) of paragraph
(a) above. In addition, in the event Seller intends to enter into a Seller
Acquisition Agreement relating to a Superior Proposal, Seller will deliver a
Seller Notice at least 24 hours prior to entering into such Seller Acquisition
Agreement, which Seller Notice will identify the third party and the material
proposed terms of such Superior Proposal. Seller will keep Buyer reasonably
informed of the status of any such request or Acquisition Proposal and will
update the information required to be provided in Seller Notice upon the request
of the Newco.

         5.06. PUBLIC ANNOUNCEMENTS. Buyer and Seller will consult with each
other before, but will not be required to obtain the other party's consent with
respect to, issuing any press release, any filing with the SEC on Form 8-K or
otherwise making any public statements with respect to this Agreement or the
Merger or the other transactions contemplated hereby, and shall not issue any
such press release, SEC Form 8-K filing or make any such public statement prior
to such consultation, except to the extent that compliance with legal
requirements requires a party to issue a press release or public announcement or
make an 8-K filing prior to such consultation. This Section 5.06 shall supersede
any conflicting provisions in the Confidentiality Agreement.

         5.07.    NOTIFICATION OF CERTAIN MATTERS.

         (a) Seller shall give prompt notice (which notice shall state that it
is delivered pursuant to Section 5.07 of this Agreement) in writing to Buyer and
Buyer shall give prompt notice in writing to Seller, of (i) the occurrence, or
failure to occur, of any event which occurrence or failure would be likely to
cause any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date of this Agreement
through the Effective Time and (ii) any material failure of Seller or Buyer, as
the case may be, or of any officer, director, employee or agent thereof, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement; provided, however, no such notification
shall affect the representations or warranties of the parties or the conditions
to the obligations of the parties hereunder.

         (b) Seller shall give prompt notice in writing (which notice shall
state that it is delivered pursuant to Section 5.07 of this Agreement) to Buyer
of any occurrence that has had or may reasonably be expected to have a Material
Adverse Effect.

         5.08.    EMPLOYMENT AND BENEFIT MATTERS

         (a) From and after the Effective Time, Buyer agrees to cause the
Surviving Corporation to provide the employees of Seller and its Subsidiaries
(the "SELLER EMPLOYEES") who remain employed after the Effective Time with the
types and levels of employee benefits which are in the aggregate at least as
favorable as those maintained by Seller prior to the Effective Time. Buyer will
cause the Surviving Corporation to treat, and cause its applicable benefit plans
to treat, the service of Seller Employees with Seller or any Subsidiary as
service rendered to the Surviving Corporation for purposes of eligibility to
participate, vesting and for other appropriate benefits but not for benefit
accrual.

         (b) Notwithstanding anything to the contrary contained herein, Buyer
shall have sole discretion with respect to the determination as to whether or
when to terminate, merge or continue any employee benefit plans and programs of
Seller after the Effective Time.


<PAGE>


         5.09.    OFFICERS' AND DIRECTORS' INDEMNIFICATION; INSURANCE.

         (a) The Surviving Corporation agrees that for a period ending on the
sixth anniversary of the Effective Time, the Surviving Corporation will maintain
all rights to indemnification (including with respect to the advancement of
expenses incurred in the defense of any action or suit) existing on the date of
this Agreement in favor of the present and former directors, officers, employees
and agents of Seller as provided in Seller's Articles of Incorporation and
By-laws , in each case as in effect on the date of this Agreement, and that
during such period, neither the Articles of Incorporation nor the Bylaws of the
Surviving Corporation shall be amended to reduce or limit the rights of
indemnity afforded to the present and former directors, officers, employees and
agents of Seller, or the ability of the Surviving Corporation to indemnify them,
nor to hinder, delay or make more difficult the exercise of such rights or
indemnity or the ability to indemnify.

         (b) The Surviving Corporation agrees to indemnify to the fullest extent
permitted under its Articles of Incorporation, its Bylaws, and applicable law
the present and former directors, officers, employees and agents of Seller
against all losses, damages, liabilities or claims made against them arising
from their service in such capacities prior to and including the Effective Time,
to at least the same extent as such persons are currently permitted to be
indemnified pursuant to Seller's Articles of Incorporation and Bylaws for a
period ending on the sixth anniversary of the Effective Time.

         (c) Buyer will cause to be maintained for a period of three years from
the Effective Time Seller's current directors' and officers' insurance and
indemnification policy to the extent that it provides coverage for events
occurring prior to the Effective Time (the "D&O INSURANCE") for all persons who
are directors and officers of Seller on the date of this Agreement, so long as
such insurance is available on commercially reasonable terms and the annual
premium therefor would not be in excess of 200% of the last annual premium paid
prior to the date of this Agreement (the "MAXIMUM PREMIUM"). If the existing D&O
Insurance expires, is terminated or cancelled during such three-year period,
Buyer will use all reasonable efforts to cause to be obtained as much D&O
Insurance as can be obtained for the remainder of such period for an annualized
premium not in excess of the Maximum Premium, on terms and conditions no less
advantageous than the existing D&O Insurance.

         5.10.    ADDITIONAL AGREEMENTS.

         (a) Subject to the terms and conditions hereof, each of the parties to
this Agreement agrees 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 to consummate and make effective as promptly as practicable
the transactions contemplated by this Agreement (including consummation of the
Merger) and to cooperate with each other in connection with the foregoing.

         (b) Subject to the terms and conditions hereof, each of the parties to
this Agreement agrees to use commercially reasonable efforts to: (i) obtain all
necessary waivers, consents and approvals from other parties to loan agreements,
leases, licenses and other contracts, (ii) obtain all necessary consents,
approvals and authorizations as required to be obtained under any federal, state
or foreign law or regulations, (iii) defend all lawsuits or other legal
proceedings challenging this Agreement or the consummation of the transactions
contemplated hereby, (iv) lift or rescind any injunction or restraining order or
other order adversely affecting the ability of the parties to consummate the
transactions contemplated hereby, (v) effect all necessary registrations and
filings, including, but not limited to, submissions of information requested by
Governmental Entities, and (vi) fulfill all conditions to this Agreement.

         (c) In connection with and without limiting the foregoing, Seller and
its Board of Directors shall (i) take all action necessary to ensure that no
state takeover statute or similar statute or regulation is or becomes applicable
to the Offer, the Merger, this Agreement or any of the other transactions
contemplated by this Agreement and (ii) if any state takeover statute or similar
statute or regulation becomes applicable to the Offer, the Merger, this
Agreement or any other transaction contemplated by this Agreement, take all
action necessary


<PAGE>

to ensure that the Offer, the Merger, this Agreement and the other transactions
contemplated by this Agreement may be consummated as promptly as practicable on
the terms contemplated by the Offer and this Agreement and otherwise to minimize
the effect of such statute or regulation on the Offer, the Merger or this
Agreement and the other transactions contemplated by this Agreement.

         5.11. SELLER INDEBTEDNESS. Prior to the Effective Time, Seller shall
cooperate with Buyer in taking such actions requested by Buyer as are reasonably
appropriate or necessary in connection with the redemption, prepayment,
modification, satisfaction or elimination of any outstanding Indebtedness of
Seller or any of its Subsidiaries with respect to which a consent is required to
be obtained to effectuate the Merger and the transactions contemplated by this
Agreement and has not been so obtained.

         5.12. UPDATE OF DISCLOSURE SCHEDULES. Each party agrees that, with
respect to the representations and warranties of such party contained in this
Agreement, such party shall have the continuing obligation until the Closing to
supplement or amend promptly the Schedules hereto with respect to any matter
hereafter arising or discovered which, if existing or known at the date of this
Agreement, would have been required to be set forth or described in the
Schedules. For all purposes of this Agreement, including without limitation for
purposes of determining whether the conditions set forth in Section 6.02(a) and
6.03(a) have been fulfilled, the Schedules hereby shall be deemed to include
only that information contained therein on the date of this Agreement and shall
be deemed to exclude all information contained in any supplement or amendment
thereto.

         5.13. FUTURE FILINGS. Seller will deliver to Buyer as soon as they
become available true and complete copies of any report or statement mailed by
it to its stockholders generally or filed by it with the SEC subsequent to the
date of this Agreement and prior to the Effective Time. As of their respective
dates, such reports and statements (excluding any information therein provided
by Buyer, as to which Seller makes no representation) will not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they are made, not misleading and will comply as to
form in all material respects with all applicable requirements of law. The
consolidated financial statements of Seller to be included in such reports and
statements (excluding any information therein provided by Buyer, as to which
Seller makes no representation) will be prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods involved (except (i) as otherwise indicated in such financial statements
and the notes thereto or (ii) in the case of unaudited interim statements, to
the extent permitted under Form 10-QSB under the Exchange Act) and will present
fairly the consolidated financial position, results of operations and cash flows
of Seller as of the dates thereof and for the periods indicated therein
(subject, in the case of any unaudited interim financial statements, to normal
year-end audit adjustments). Buyer shall deliver to Seller as soon as they
become available, true and complete copies of any report or statement mailed by
it to Seller's stockholders generally or filed by it with the SEC subsequent to
the date of this Agreement and prior to the Effective Time.

         5.14. FINANCING. As soon as practicable after the date hereof, Buyer
shall use its best efforts and take all actions necessary to complete the Share
Issuance pursuant to which the New Buyer Shares will be offered for sale to the
public in accordance with the Placing Agreement. Buyer shall use its best
efforts and take all actions necessary to cause the New Buyer Shares to be
admitted to the London Stock Exchange's Official List. Buyer will notify Seller
promptly in the event that Buyer becomes aware of any facts, circumstances or
developments that would create reasonable doubt regarding the completion prior
to the Closing Date of the Share Issuance. Prior to the Effective Time, Buyer
shall contribute the proceeds of the Share Issuance to Newco and Newco shall use
such proceeds solely to complete the Offer in accordance with its terms and pay
the Merger Consideration and other amounts payable pursuant to Article II
hereof.

         5.15. MEETING OF STOCKHOLDERS OF BUYER. Promptly after the execution
and delivery of this Agreement, Buyer shall duly call, give notice of, convene
and hold a meeting of its shareholders (the "BUYER SPECIAL MEETING") to consider
and vote upon this Agreement, the Merger and the Share Issuance, and shall,
through its Board of Directors, recommend to its shareholders the approval and
adoption of the Merger, this Agreement, and the Share Issuance. Buyer shall use
reasonable efforts to solicit from stockholders of Buyer


<PAGE>

proxies in favor of such adoption and approval and, subject to the rules of the
London Stock Exchange and the duties of the directors of Buyer under the laws of
England, to take all other action necessary to secure the vote or consent of
stockholders required by the laws of the United Kingdom to effect the Merger and
the Share Issuance. On or prior to the date hereof, each of the directors of
Buyer has delivered a written irrevocable commitment to Seller that they will
vote their shares of Buyer stock at the Buyer Special Meeting in favor of the
Merger, the Merger Agreement and the Share Issuance.

         5.16. COMPLETION OF BRIDGESTONE TRANSACTION. Seller shall use its best
efforts to complete the transactions contemplated by the Bridgestone Agreement
substantially in accordance with its terms.

         5.17. DIRECTORS. Promptly upon the acceptance for payment of, and
payment for, Shares by Buyer pursuant to the Offer, Buyer shall be entitled to
designate such number of directors on the Board of Directors of Seller as will
give Buyer, subject to compliance with Section 14(f) of the Exchange Act,
representation on Seller's Board of Directors equal to the product of (i) the
total number of directors on Seller's Board of Directors and (ii) the percentage
that the number of shares of Seller Common Stock purchased by Buyer in the Offer
bears to the number of shares of Seller Common Stock outstanding, and Seller
shall, at such time, cause Buyer's designees to be so elected by its existing
Board of Directors; provided, that in the event that Buyer's designees are
elected to the Board of Directors of Seller, until the Effective Time such Board
of Directors shall have at least two directors who are directors of Seller on
the date of this Agreement and who are not officers of Seller or any of its
Subsidiaries (the "INDEPENDENT DIRECTORS") and; provided further that, in such
event, if the number of Independent Directors shall be reduced below two for any
reason whatsoever, the remaining Independent Director shall designate a person
to fill such vacancy who shall be deemed to be an Independent Director for
purposes of this Agreement or, if no Independent Directors then remain, the
other directors of Seller on the date hereof shall designate two persons to fill
such vacancies who shall not be officers or affiliates of Seller or any of its
Subsidiaries, or officers or affiliates of Buyer or any of its Subsidiaries, and
such persons shall be deemed to be Independent Directors for purposes of this
Agreement. Subject to applicable law, Seller shall take all action requested by
Buyer necessary to effect any such election, including mailing to its
stockholders the Information Statement containing the information required by
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and
Seller agrees to make such mailing with the mailing of the Schedule 14D-9
(provided that Buyer shall have provided to Seller on a timely basis all
information required to be included in the Information Statement with respect to
Buyer's designees). In connection with the foregoing, Seller will promptly, at
the option of Buyer, either increase the size of the Seller's Board of Directors
and/or obtain the resignation of such number of its current directors as is
necessary to enable Buyer's designees to be elected or appointed to, and to
constitute a majority of Seller's Board of Directors as provided above.

         2.  THE TERM LOAN.

                  2.1. COMMITMENT TO LEND. Subject to the terms and conditions
         set forth in this Loan Agreement, the Lender agrees to lend on the
         Drawdown Date in a single draw such amount as requested by the Borrower
         up to a maximum aggregate principal amount of $10,000,000. The Drawdown
         Date shall occur on any single date from the Closing Date up to and
         including the Drawdown Termination Date upon notice by the Borrower to
         the Lender given in accordance with Section 2.4. The Borrower's request
         for the Loan hereunder shall constitute a representation and warranty
         by the Borrower that the conditions set forth in Section 8 and Section
         9 have been satisfied on the date of such request.

                  2.2. REPAYMENT OF THE LOAN. The Borrower hereby absolutely and
         unconditionally promises to pay the Lender on the Maturity Date the
         entire unpaid principal amount of the Loan then outstanding and the
         entire unpaid amount of all other Obligations (except as may be
         expressly waived in writing by the Lender).

                  2.3. THE NOTE. The Loan shall be evidenced by a promissory
         note of the Borrower in substantially the form of EXHIBIT A hereto (the
         "NOTE"), dated the Closing Date and completed with appropriate
         insertions. The Note shall be payable to the order of the Lender in a
         principal amount equal to the aggregate principal amount of the Loan
         and representing the obligation of the Borrower to pay to the Lender
         such principal amount or, if less, the outstanding amount of the Loan,
         plus interest accrued thereon, as set forth below. The Borrower
         irrevocably authorizes the Lender to make or cause to be made a
         notation on the Note Record reflecting the original principal amount of
         the Loan and, at or about the time of the Lender's receipt of any
         principal payment on the Note, an appropriate notation on the Note
         Record reflecting such payment. The aggregate unpaid amount set forth
         on the Note Record shall be PRIMA FACIE evidence of the principal
         amount thereof owing and unpaid to the Lender, but the failure to
         record, or any error in so recording, any such amount on the Note
         Record shall not affect the obligations of the Borrower hereunder or
         under the Note to make payments of principal of and interest on the
         Note when due.

                  2.4. REQUEST FOR LOAN. The Borrower shall give to the Lender
written notice in the form of EXHIBIT B hereto (or telephonic notice confirmed
in a writing in the form of EXHIBIT B hereto) of the Loan requested hereunder (a
"LOAN REQUEST") no less than two (2) Business Days prior to the proposed
Drawdown Date. Such notice shall specify (a) the principal amount of the Loan
requested, and (b) the proposed Drawdown Date of Loan. Such notice shall be
irrevocable and binding on the Borrower and shall obligate the Borrower to
accept the Loan requested from the Lender on the proposed Drawdown Date.

                  2.5. OPTIONAL PREPAYMENT OF LOAN. The Borrower shall have the
         right at any time to prepay the Note on or before the Maturity Date, as
         a whole, or in part, upon not less than three (3) Business Days prior
         written notice to the Lender, without premium or penalty, PROVIDED that
         each partial prepayment shall be in the principal amount of $500,000 or
         an integral multiple thereof. Any


<PAGE>

         prepayment of principal of the Loan shall include all fees and interest
         accrued to the date of prepayment. No amount repaid with respect to the
         Loan may be reborrowed.

                  2.6. INTEREST ON LOAN. Except as otherwise provided in Section
         3.7, the outstanding amount of the Loan shall bear interest at the rate
         of two percent (2%) per annum above the Lender's Cost of Funds as in
         effect from time to time[; provided, that in the event the Merger
         Agreement is terminated solely because (a) the Lender's shareholders
         failed to approve the Merger, or (b) the Lender failed to obtain the
         financing necessary to complete the Merger, or (c) a material breach by
         the Lender of any Merger Document, then commencing as of the Drawdown
         Date and continuing thereafter the outstanding amount of the Loan shall
         bear interest at the rate of one-half percent (1/2%) per annum above
         the Lender's Cost of Funds as in effect from time to time]. Interest
         shall be payable monthly in arrears on the first day of each calendar
         month for the immediately preceding calendar month, commencing on the
         first such date following the Drawdown Date, and on the Maturity Date.
         Any change in the interest rate resulting from a change in the Lender's
         Cost of Funds is to be effective at the beginning of the day of such
         change in the Lender's Cost of Funds. The Lender will give the Borrower
         prompt notice in writing of any change in the Lender's Cost of Funds.
         The Borrower promises to pay interest on the amount of the Loan
         outstanding from time to time from the Drawdown Date until the earlier
         of the Maturity Date or payment in full of the Obligations in
         accordance with the provisions of this Section 2.6.

         3.  CERTAIN GENERAL PROVISIONS.

                  3.1. CLOSING FEE. Unless otherwise expressly waived in writing
         by the Lender in accordance with the terms hereof, the Borrower agrees
         to pay to the Lender on the Maturity Date a closing fee in the amount
         of $1,700,000 (the "CLOSING FEE"). For the avoidance of doubt, each of
         the Borrower and the Lender agree that the Closing Fee shall be deemed
         fully earned by the Lender on the Closing Date; PROVIDED, that prior to
         the Maturity Date the Closing Fee shall not bear interest and
         commencing on the Maturity Date and thereafter the Closing Fee shall
         bear interest at the rate of six (6%) per annum above the Lender's Cost
         of Funds until the Closing Fee is paid in full in cash or otherwise
         waived. The Lender agrees to waive the Closing Fee if, as at the
         Maturity Date, (a) the Borrower has completed its merger with a
         wholly-owned Subsidiary of the Lender pursuant to the terms and
         conditions set forth in the Merger Agreement and the other Merger
         Documents (the "Merger"), or (b) the Merger Agreement has been
         terminated solely because either (i) the Lender's shareholders failed
         to approve the Merger, or (ii) the Lender failed to obtain the
         financing necessary to complete the Merger, or (c) a material breach by
         the Lender of any Merger Document.

                  3.2.  FUNDS FOR PAYMENTS.

                           3.2.1. PAYMENTS TO LENDER. All payments of principal,
                  interest, fees and any other amounts due hereunder or under
                  any of the other Loan Documents shall be made on the due date
                  thereof to the Lender in Dollars at the Lender's Head Office
                  or at such other place that the Lender may from time to time
                  designate, in each case such payment shall be sent by the
                  Borrower not later than 11:00 a.m. (Denver, Colorado time) and
                  in immediately available funds; PROVIDED, that in calculating
                  interest hereunder such payment shall only be credited to the
                  Borrower's account when it is actually received by the Lender
                  at the Lender's Head Office or at such other place as the
                  Lender has designated.

                           3.2.2. NO OFFSET, ETC. All payments by the Borrower
                  hereunder and under any of the other Loan Documents shall be
                  made without recoupment, setoff or counterclaim and free and
                  clear of and without deduction for any taxes, levies, imposts,
                  duties, charges, fees, deductions, withholdings, compulsory
                  loans, restrictions or conditions of any nature now or
                  hereafter imposed or levied by any jurisdiction or any
                  political subdivision thereof or taxing or other authority
                  therein unless the Borrower is compelled by law to make such
                  deduction or withholding. If any such obligation is imposed
                  upon the Borrower with respect to any amount


<PAGE>

                  payable by it hereunder or under any of the other Loan
                  Documents, the Borrower will pay to the Lender on the date on
                  which such amount is due and payable hereunder or under such
                  other Loan Document, such additional amount in Dollars as
                  shall be necessary to enable the Lender to receive the same
                  net amount which the Lender would have received on such due
                  date had no such obligation been imposed upon the Borrower.
                  The Borrower will deliver promptly to the Lender certificates
                  or other valid vouchers for all taxes or other charges
                  deducted from or paid with respect to payments made by the
                  Borrower hereunder or under such other Loan Document.

                  3.3. COMPUTATIONS. All computations of interest on the Loan
         and of other fees shall be based on a 360-day year and paid for the
         actual number of days elapsed. Whenever a payment hereunder or under
         any of the other Loan Documents becomes due on a day that is not a
         Business Day, the due date for such payment shall be extended to the
         next succeeding Business Day, and interest shall accrue during such
         extension. In the absence of manifest error, the outstanding amount of
         the Loan as reflected on the Note Record from time to time shall be
         considered correct and binding on the Borrower unless within five (5)
         Business Days after receipt of any notice by the Lender of such
         outstanding amount, the Lender shall notify the Borrower to the
         contrary.

                  3.4. ADDITIONAL COSTS, ETC. If any present or future
         applicable law, which expression, as used herein, includes statutes,
         rules and regulations thereunder and interpretations thereof by any
         competent court or by any governmental or other regulatory body or
         official charged with the administration or the interpretation thereof
         and requests, directives, instructions and notices at any time or from
         time to time hereafter made upon or otherwise issued to the Lender by
         any regulatory authority (whether or not having the force of law),
         shall:

                           (a) subject the Lender to any tax, levy, impost,
                  duty, charge, fee, deduction or withholding of any nature with
                  respect to this Loan Agreement, the other Loan Documents, or
                  the Note (other than taxes based upon or measured by the
                  income or profits of the Lender), or

                           (b) materially change the basis of taxation (except
                  for changes in taxes on income or profits) of payments to the
                  Lender of the principal of or the interest on the Loan or any
                  other amounts payable to the Lender under this Loan Agreement
                  or the other Loan Documents, or

                           (c) impose or increase or render applicable (other
                  than to the extent specifically provided for elsewhere in this
                  Loan Agreement) any special deposit, reserve, assessment,
                  liquidity, capital adequacy or other similar requirements
                  (whether or not having the force of law) against assets held
                  by, or deposits in or for the account of, or loans by, or
                  commitments of an office of the Lender, or

                           (d) impose on the Lender any other conditions or
                  requirements with respect to this Loan Agreement, the other
                  Loan Documents, or the Note, and the result of any of the
                  foregoing is

                                    (i) to increase the cost to the Lender of
                           making, funding, issuing, renewing, extending or
                           maintaining the Loan, or

                                    (ii) to reduce the amount of principal,
                           interest, or other amount payable to the Lender
                           hereunder on account of the Loan, or

                                    (iii) to require the Lender to make any
                           payment or to forego any interest or other sum
                           payable hereunder, the amount of which payment or
                           foregone interest or other sum is calculated by
                           reference to the gross amount of any sum receivable
                           or deemed received by the Lender from the Borrower
                           hereunder,


<PAGE>

         then, and in each such case, the Borrower will, upon demand made by the
         Lender at any time and from time to time and as often as the occasion
         therefor may arise, pay to the Lender such additional amounts as will
         be sufficient to compensate the Lender for such additional cost,
         reduction, payment or foregone interest or other sum.

                  3.5. CERTIFICATE. A certificate setting forth any additional
         amounts payable pursuant to Section 3.4 and a brief explanation of such
         amounts which are due, submitted by the Lender to the Borrower, shall
         be conclusive, absent manifest error, that such amounts are due and
         owing.

                  3.6. INDEMNITY. The Borrower agrees to indemnify the Lender
         and to hold the Lender harmless from and against any loss, cost or
         expense that the Lender may sustain or incur as a consequence of (a)
         default by the Borrower in payment of the principal amount of or any
         interest on the Loan as and when due and payable, including any such
         loss or expense arising from interest or fees payable by the Lender to
         lenders of funds obtained by it in order to maintain the Loan, (b)
         default by the Borrower in making a borrowing after the Borrower has
         given (or is deemed to have given) a Loan Request, or (c) the making of
         any payment on the Loan on a day that is not the Maturity Date,
         including interest or fees payable by the Lender to lenders of funds
         obtained by it in order to maintain the Loan.

                  3.7.  INTEREST AFTER DEFAULT.

                           3.7.1. OVERDUE AMOUNTS. Overdue principal and (to the
                  extent permitted by applicable law) interest on the Loan and
                  all other overdue amounts payable hereunder or under any of
                  the other Loan Documents shall bear interest compounded
                  monthly and payable on demand at a rate per annum equal to
                  four percent (4%) above the otherwise applicable rate until
                  such amount shall be paid in full (after as well as before
                  judgment).

                           3.7.2. AMOUNTS NOT OVERDUE. During the continuance of
                  a Default or an Event of Default the principal of the Loan not
                  overdue shall, until such Default or Event of Default has been
                  cured or remedied or such Default or Event of Default has been
                  waived in writing by the Lender, bear interest at a rate per
                  annum equal to four percent (4%) above the otherwise
                  applicable rate.

                  3.8. USURY PROVISION. It is not the intention of any parties
         to this Loan Agreement to make an agreement in violation of the laws of
         any applicable jurisdiction relating to usury. Regardless of any
         provision of this Loan Agreement or of any other Loan Document, the
         Lender shall not be entitled to receive, collect or apply, as interest,
         charges, fees, penalties or additional amounts (collectively, referred
         to herein as "INTEREST") on any of the Loans or any other Obligation,
         any amount in excess of the Highest Lawful Rate. If under the laws of
         any applicable jurisdiction there is no legal limitation on the rate of
         Interest that may be charged with respect to an obligation owing to the
         Lender (including, without limitation, the outstanding principal amount
         of the Loan, unpaid interest with respect to the Loan or any other
         Obligations due and payable under any Loan Document), there shall be no
         maximum amount applicable to such obligation, notwithstanding any
         reference thereto herein or in any other Loan Document. If at any time
         the rate at which interest is payable to the Lender on the Loan or any
         other Obligation exceeds the Highest Lawful Rate, the Loan or other
         Obligation shall bear interest at the Highest Lawful Rate only but
         shall continue to bear interest at the Highest Lawful Rate until such
         time as the total amount of interest accrued on the Loan or other
         Obligation equals (but does not exceed) the total amount of interest
         which would have accrued thereon had there been no Highest Lawful Rate
         applicable thereto. If at the maturity or final payment of the Loan or
         other Obligation (whether at stated maturity, by acceleration or
         prepayment or otherwise) the total amount of interest which has then
         accrued or been paid thereon as provided above (the "COLLECTED
         INTEREST") is less than the total amount of interest which would have
         accrued thereon had there been no Highest Lawful Rate applicable
         thereto (the "UNRESTRICTED INTEREST"), then the Borrower shall, in
         addition to the Collected Interest, pay to the Lender an amount equal
         to (a) the lesser of the Unrestricted Interest owed or accrued for the
         benefit of


<PAGE>

         the Lender and the total amount of interest which would have accrued
         thereon for the benefit of the Lender had the Loan or other Obligation
         at all times borne Interest at the Highest Lawful Rate, MINUS (b) the
         Collected Interest paid for the account of the Lender. This Section 3.8
         shall control every provision of every agreement pertaining to the
         transactions contemplated by or contained in this Loan Agreement or any
         of the other Loan Documents and shall equally apply to any guaranty or
         other obligation of any Subsidiary of the Borrower or of any other
         Person under the Loan Documents as if such obligations were
         "Obligations" as defined herein.

         4.  SECURITY AND GUARANTIES.

                  4.1. SECURITY OF BORROWER. The Obligations shall be secured by
         a perfected security interest (subject only to the Permitted Liens
         entitled to priority under applicable law) in all of the assets of the
         Borrower and its Domestic Subsidiaries, whether now owned or hereafter
         acquired, pursuant to the terms of the Security Documents to which the
         Borrower or its Domestic Subsidiaries are a party.

                  4.2. GUARANTIES OF DOMESTIC SUBSIDIARIES. The Obligations
         shall also be guaranteed pursuant to the terms of the Guaranties and
         the Bridgestone Guaranty.

         5.  REPRESENTATIONS AND WARRANTIES.

         The Borrower represents and warrants to the Lender as of the date
hereof, as of the date the Loan is made and immediately following the
consummation of the Bridgestone Acquisition as follows:

                  5.1.  CORPORATE AUTHORITY.

                  organized, validly existing and in good standing under the
                  laws of its jurisdiction of incorporation or organization, (b)
                  has all requisite corporate power to own its property and
                  conduct its business as now conducted and as presently

                  corporation (or similar business entity) and is duly
                  authorized to do business in each jurisdiction where such
                  qualification is necessary except where a failure to be so
                  qualified would not have a materially adverse effect on the
                  business, assets or financial condition of the Borrower or its
                  Subsidiaries.

                           5.1.2. AUTHORIZATION. The execution, delivery and
                  performance of this Loan Agreement and the other Loan
                  Documents to which the Borrower or any of its Subsidiaries is
                  or is to become a party and the transactions contemplated
                  hereby and thereby (a) are within the corporate (or similar)
                  authority of such Person, (b) have been duly authorized by all
                  necessary corporate (or similar organizational) proceedings,
                  (c) do not conflict with or result in any breach or
                  contravention of any provision of law, statute, rule or
                  regulation to which the Borrower or any of its Subsidiaries is
                  subject or any judgment, order, writ, injunction, license or
                  permit applicable to such Person, (d) do not conflict with any
                  provision of the corporate charter or bylaws or other
                  organizational or constitutive documents of, or any agreement
                  or other instrument binding upon, the Borrower or any of its
                  Subsidiaries, and (e) except for the Liens granted in favor of
                  the Lender under this Loan Agreement and the other Loan
                  Documents, do not result in the creation or imposition of any
                  Lien on any undertaking, assets, rights or revenues of the
                  Borrower or its Subsidiaries.

                           5.1.3. ENFORCEABILITY. The execution and delivery of
                  this Loan Agreement and the other Loan Documents to which the
                  Borrower or any of its Subsidiaries is or is to become a party
                  will result in valid and legally binding obligations of such
                  Person enforceable against it in accordance with the
                  respective terms and provisions hereof and thereof, except as
                  enforceability is limited by bankruptcy, insolvency,
                  reorganization, moratorium or other laws relating to or

<PAGE>

                  affecting generally the enforcement of creditors' rights and
                  except to the extent that availability of the remedy of
                  specific performance or injunctive relief is subject to the
                  discretion of the court before which any proceeding therefor
                  may be brought.

                  5.2. GOVERNMENTAL APPROVALS. The execution, delivery and
         performance by the Borrower and any of its Subsidiaries of this Loan
         Agreement and the other Loan Documents to which the Borrower or any of
         its Subsidiaries is or is to become a party and the transactions
         contemplated hereby and thereby do not require the approval or consent
         of, or filing with, any governmental agency or authority other than
         those already obtained.

                  5.3. TITLE TO PROPERTIES; LEASES. Except as indicated on
         SCHEDULE 5.3 hereto, the Borrower and its Subsidiaries own all of the
         assets reflected in the consolidated balance sheet of the Borrower and
         its Subsidiaries as at the Balance Sheet Date or acquired since that
         date (except property and assets sold or otherwise disposed of in the
         ordinary course of business since that date), subject to no rights of
         others, including any mortgages, leases, conditional sales agreements,
         title retention agreements, liens or other encumbrances except
         Permitted Liens.

                  5.4.  FISCAL YEAR; FINANCIAL STATEMENTS.

                           5.4.1. FISCAL AND FINANCIAL YEAR. The Borrower and
                  each of its Subsidiaries has a fiscal year (or financial year,
                  as applicable) which is the twelve months ending on March 31
                  of each calendar year.

                           5.4.2. FINANCIAL STATEMENTS. There has been furnished
                  to the Lender a consolidated balance sheet of the Borrower and
                  its Subsidiaries as at the Balance Sheet Date, and a
                  consolidated statement of income for the fiscal year then
                  ended, certified by the Borrower's independent certified
                  public accountants. Such balance sheet and statement of income
                  have been prepared in accordance with generally accepted
                  accounting principles and fairly present the financial
                  condition of the Borrower as at the close of business on the
                  date thereof and the results of operations for the fiscal year
                  then ended. There are no contingent liabilities of the
                  Borrower or any of its Subsidiaries as of such date involving
                  material amounts, known to the officers of the Borrower not
                  disclosed in said balance sheet and the related notes thereto.

                  5.5. NO MATERIAL CHANGES, ETC. Since the Balance Sheet Date
         there has occurred no materially adverse change in the financial
         condition or business of the Borrower and its Subsidiaries as shown on
         or reflected in the consolidated balance sheet of the Borrower and its
         Subsidiaries as at the Balance Sheet Date, or the consolidated
         statement of income for the fiscal year then ended, other than changes
         in the ordinary course of business that have not had any materially
         adverse effect either individually or in the aggregate on the business
         or financial condition of the Borrower or its Subsidiaries. Except as
         set forth on SCHEDULE 5.5, since the Balance Sheet Date the Borrower
         has not made any Distribution.

                  5.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. Each of the
         Borrower and its Subsidiaries possesses all franchises, patents,
         copyrights, trademarks, trade names, licenses and permits, and rights
         in respect of the foregoing, adequate for the conduct of its business
         substantially as now conducted without known conflict with any rights
         of others.

                  5.7. LITIGATION. There are no actions, suits, proceedings or
         investigations of any kind pending or threatened against the Borrower
         or any of its Subsidiaries before any court, tribunal or administrative
         agency or board that, if adversely determined, might, either in any
         case or in the aggregate, materially adversely affect the properties,
         assets, financial condition or business of the Borrower and its
         Subsidiaries or materially impair the right of the Borrower and its
         Subsidiaries, considered as a whole, to carry on business substantially
         as now conducted by them, or result in any substantial liability not
         adequately covered by insurance, or for which adequate reserves are not
         maintained on the consolidated


<PAGE>

         balance sheet of the Borrower, or which question the validity of this
         Loan Agreement or any of the other Loan Documents, or any action taken
         or to be taken pursuant hereto or thereto.

                  5.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the
         Borrower nor any of its Subsidiaries is subject to any charter,
         corporate or other legal restriction, or any judgment, decree, order,
         rule or regulation that has or is expected in the future to have a
         materially adverse effect on the business, assets or financial
         condition of the Borrower or any of its Subsidiaries. Neither the
         Borrower nor any of its Subsidiaries is a party to any contract or
         agreement that has or is expected, in the judgment of the Borrower's
         officers, to have any materially adverse effect on the business of the
         Borrower or any of its Subsidiaries.

                  5.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the
         Borrower nor any of its Subsidiaries is in violation of any provision
         of its charter documents, bylaws, or any agreement or instrument to
         which it may be subject or by which it or any of its properties may be
         bound or any decree, order, judgment, statute, license, rule or
         regulation, in any of the foregoing cases in a manner that could result
         in the imposition of substantial penalties or materially and adversely
         affect the financial condition, properties or business of the Borrower
         or any of its Subsidiaries.

                  5.10. TAX STATUS. The Borrower and its Subsidiaries (a) have
         made or filed all federal, state and foreign income and all other tax
         returns, reports and declarations required by any jurisdiction to which
         any of them is subject, (b) have paid all taxes and other governmental
         assessments and charges shown or determined to be due on such returns,
         reports and declarations, except those being contested in good faith
         and by appropriate proceedings and (c) have set aside on their books
         provisions reasonably adequate for the payment of all taxes for periods
         subsequent to the periods to which such returns, reports or
         declarations apply. There are no unpaid taxes in any material amount
         claimed to be due by the taxing authority of any jurisdiction, and the
         officers of the Borrower know of no basis for any such claim.

                  5.11. NO EVENT OF DEFAULT. No Default or Event of Default has
         occurred and is continuing.

                  5.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the
         Borrower nor any of its Subsidiaries is a "holding company", or a
         "subsidiary company" of a "holding company", or an affiliate" of a
         "holding company", as such terms are defined in the Public Utility
         Holding Company Act of 1935; nor is it an "investment company", or an
         "affiliated company" or a "principal underwriter" of an "investment
         company", as such terms are defined in the Investment Company Act of
         1940.

                  5.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except with
         respect to Permitted Liens, there is no financing statement, security
         agreement, chattel mortgage, real estate mortgage or other document
         filed or recorded with any filing records, registry, or other public
         office, that purports to cover, affect or give notice of any present or
         possible future lien on, or security interest in, any assets or
         property of the Borrower or any of its Subsidiaries or rights
         thereunder.

                  5.14. PERFECTION OF SECURITY INTEREST. All filings,
         assignments, pledges and deposits of documents or instruments have been
         made and all other actions have been taken that are necessary or
         advisable, under applicable law, to establish and perfect the Lender's
         security interest in the Collateral. The Collateral and the Lender's
         rights with respect to the Collateral are not subject to any setoff,
         claims, withholdings or other defenses. The Borrower is the owner of
         the Collateral free from any Lien, except for Permitted Liens.

                  5.15. CERTAIN TRANSACTIONS. Except for arm's length
         transactions pursuant to which the Borrower or any of its Subsidiaries
         makes payments in the ordinary course of business upon terms no less
         favorable than the Borrower or such Subsidiary could obtain from third
         parties, none of the officers, directors, or employees of the Borrower
         or any of its Subsidiaries is presently a party to any transaction with
         the Borrower or any of its Subsidiaries (other than for services as
         employees, officers and


<PAGE>

         directors), including any contract, agreement or other arrangement
         providing for the furnishing of services to or by, providing for rental
         of real or personal property to or from, or otherwise requiring
         payments to or from any officer, director or such employee or, to the
         knowledge of the Borrower, any corporation, partnership, trust or other
         entity in which any officer, director, or any such employee has a
         substantial interest or is an officer, director, trustee or partner.

                  5.16.  EMPLOYEE BENEFIT PLANS.

                           5.16.1. IN GENERAL. Each Employee Benefit Plan and
                  each Guaranteed Pension Plan has been maintained and operated
                  in compliance in all material respects with the provisions of
                  ERISA and/or all Applicable Pension Legislation and, to the
                  extent applicable, the Code, including but not limited to the
                  provisions thereunder respecting prohibited transactions and
                  the bonding of fiduciaries and other persons handling plan
                  funds as required by Section 412 of ERISA. The Borrower has
                  heretofore delivered to the Lender the most recently completed
                  annual report, Form 5500, with all required attachments, and
                  actuarial statement required to be submitted under Section
                  103(d) of ERISA, with respect to each Guaranteed Pension Plan.

                           5.16.2. TERMINABILITY OF WELFARE PLANS. No Employee
                  Benefit Plan, which is an employee welfare benefit plan within
                  the meaning of Section 3(1) or Section 3(2)(B) of ERISA,
                  provides benefit coverage subsequent to termination of
                  employment, except as required by Title I, Part 6 of ERISA or
                  the applicable state insurance laws. The Borrower may
                  terminate each such Plan at any time (or at any time
                  subsequent to the expiration of any applicable bargaining
                  agreement) in the discretion of the Borrower without liability
                  to any Person other than for claims arising prior to
                  termination.

                           5.16.3. GUARANTEED PENSION PLANS. Each contribution
                  required to be made to a Guaranteed Pension Plan, whether
                  required to be made to avoid the incurrence of an accumulated
                  funding deficiency, the notice or lien provisions of Section
                  302(f) of ERISA, or otherwise, has been timely made. No waiver
                  of an accumulated funding deficiency or extension of
                  amortization periods has been received with respect to any
                  Guaranteed Pension Plan, and neither the Borrower nor any
                  ERISA Affiliate is obligated to or has posted security in
                  connection with an amendment to a Guaranteed Pension Plan
                  pursuant to Section 307 of ERISA or Section 401(a)(29) of the
                  Code. No liability to the PBGC (other than required insurance
                  premiums, all of which have been paid) has been incurred by
                  the Borrower or any ERISA Affiliate with respect to any
                  Guaranteed Pension Plan and there has not been any ERISA
                  Reportable Event (other than an ERISA Reportable Event as to
                  which the requirement of 30 days notice has been waived), or
                  any other event or condition which presents a material risk of
                  termination of any Guaranteed Pension Plan by the PBGC. Based
                  on the latest valuation of each Guaranteed Pension Plan (which
                  in each case occurred within twelve months of the date of this
                  representation), and on the actuarial methods and assumptions
                  employed for that valuation, the aggregate benefit liabilities
                  of all such Guaranteed Pension Plans within the meaning of
                  Section 4001 of ERISA did not exceed the aggregate value of
                  the assets of all such Guaranteed Pension Plans, disregarding
                  for this purpose the benefit liabilities and assets of any
                  Guaranteed Pension Plan with assets in excess of benefit
                  liabilities.

                           5.16.4. MULTIEMPLOYER PLANS. Neither the Borrower nor
                  any ERISA Affiliate has incurred any material liability
                  (including secondary liability) to any Multiemployer Plan as a
                  result of a complete or partial withdrawal from such
                  Multiemployer Plan under Section 4201 of ERISA or as a result
                  of a sale of assets described in Section 4204 of ERISA.
                  Neither the Borrower nor any ERISA Affiliate has been notified
                  that any Multiemployer Plan is in reorganization or insolvent
                  under and within the meaning of Section 4241 or Section 4245
                  of ERISA or is at risk of entering reorganization or becoming
                  insolvent, or that any Multiemployer Plan intends to terminate
                  or has been terminated under Section 4041A of ERISA.

                  5.17. USE OF PROCEEDS. The proceeds of the Loan shall be used
solely to finance the acquisition by the Borrower of 100% of the issued and
outstanding common stock of Bridgestone and other transactions in connection
therewith (the "BRIDGESTONE ACQUISITION"), all in accordance with the terms of
and pursuant to the Bridgestone Acquisition Documents.

                  5.18. ENVIRONMENTAL COMPLIANCE. The Borrower has taken all
         necessary steps to investigate the past and present condition and usage
         of the Real Estate and the operations conducted thereon and, based upon
         such diligent investigation, has determined that:

                           (a) none of the Borrower, its Subsidiaries or any
                  operator of the Real Estate or any operations thereon is in
                  violation, or alleged violation, of any judgment, decree,
                  order, law, license, rule or regulation pertaining to
                  environmental matters, including without limitation, those
                  arising under the Resource Conservation and Recovery Act
                  ("RCRA"), the Comprehensive Environmental Response,
                  Compensation and Liability Act of 1980 as amended ("CERCLA"),
                  the Superfund Amendments and Reauthorization Act of 1986
                  ("SARA"), the Federal Clean Water Act, the Federal Clean Air
                  Act, the Toxic Substances Control Act, or any state or local
                  statute, regulation, ordinance, order or decree relating to
                  health, safety or the environment in the United Kingdom,
                  France, Germany, the European Union or other applicable
                  jurisdiction (hereinafter "ENVIRONMENTAL LAWS"), which
                  violation would have a material adverse effect on the
                  environment or the business, assets or financial condition of
                  the Borrower or any of its Subsidiaries;

                           (b) neither the Borrower nor any of its Subsidiaries
                  has received notice from any third party including, without
                  limitation, any federal, state or local governmental
                  authority, (i) that any one of them has been identified by the
                  United States Environmental Protection Agency ("EPA") as a
                  potentially responsible party under CERCLA with respect to a
                  site listed on the National Priorities List, 40 C.F.R. Part
                  300 Appendix B; (ii) that any hazardous waste, as defined by
                  42 U.S.C. Section 6903(5), any hazardous substances as defined
                  by 42 U.S.C. Section 9601(14), any pollutant or contaminant as
                  defined by 42 U.S.C. Section 9601(33), any waste substance or
                  other material as defined in the Environmental Protection Act
                  1990 (United Kingdom), and any toxic substances, oil or
                  hazardous materials or other chemicals or substances regulated
                  by any Environmental Laws ("HAZARDOUS SUBSTANCES") which any
                  one of them has generated, transported or disposed of has been
                  found at any site at which a federal, state or local agency or
                  authority in any other applicable jurisdiction, or other third
                  party has conducted or has ordered that the Borrower or any of
                  its Subsidiaries conduct a remedial investigation, removal or
                  other response action pursuant to any Environmental Law; or
                  (iii) that it is or shall be a named party to any claim,
                  action, cause of action, complaint, or legal or administrative
                  proceeding (in each case, contingent or otherwise) arising out
                  of any third party's incurrence of costs, expenses, losses or
                  damages of any kind whatsoever in connection with the release
                  of Hazardous Substances;

                           (c) except as set forth on SCHEDULE 5.18 attached
                  hereto: (i) no portion of the Real Estate has been used for
                  the handling, processing, storage or disposal of Hazardous
                  Substances except in accordance with applicable Environmental
                  Laws; and no underground tank or other underground storage
                  receptacle for Hazardous Substances is located on any portion
                  of the Real Estate; (ii) in the course of any activities
                  conducted by the Borrower, its Subsidiaries or operators of
                  its properties, no Hazardous Substances have been generated or
                  are being used on the Real Estate except in accordance with
                  applicable Environmental Laws; (iii) there have been no
                  releases (i.e. any past or present releasing, spilling,
                  leaking, pumping, pouring, emitting, emptying, discharging,
                  injecting, escaping, disposing or dumping) or threatened
                  releases of Hazardous Substances on, upon, into or from the
                  properties of the Borrower or its Subsidiaries, which releases
                  would have a material adverse effect on the value of any of
                  the Real Estate or adjacent properties or the environment;
                  (iv) to the best of the Borrower's knowledge, there have


<PAGE>

                  been no releases on, upon, from or into any real property in
                  the vicinity of any of the Real Estate which, through soil or
                  groundwater contamination, may have come to be located on, and
                  which would have a material adverse effect on the value of,
                  the Real Estate; and (v) in addition, any Hazardous Substances
                  that have been generated on any of the Real Estate have been
                  transported offsite only by carriers having an identification
                  number issued by the EPA (or by a similar agency in other
                  jurisdictions, as applicable), treated or disposed of only by
                  treatment or disposal facilities maintaining valid permits as
                  required under applicable Environmental Laws, which
                  transporters and facilities have been and are, to the best of
                  the Borrower's knowledge, operating in compliance with such
                  permits and applicable Environmental Laws; and

                           (d) None of the Borrower and its Subsidiaries or any
                  of the other Real Estate is subject to any applicable
                  environmental law requiring the performance of Hazardous
                  Substances site assessments, or the removal or remediation of
                  Hazardous Substances, or the giving of notice to any
                  governmental agency or the recording or delivery to other
                  Persons of an environmental disclosure document or statement
                  by virtue of the transactions set forth herein and
                  contemplated hereby, or as a condition to the recording of any
                  Mortgage or to the effectiveness of any other transactions
                  contemplated hereby.

                  5.19. SUBSIDIARIES, ETC. SCHEDULE 5.19 sets forth all the
         Subsidiaries of the Borrower, their respective jurisdictions of
         organization and principal places of business. Except as set forth on
         SCHEDULE 5.19, neither the Borrower nor any Subsidiary of the Borrower
         is engaged in any joint venture or partnership with any other Person.

                  5.20. YEAR 2000 PROBLEM. The Borrower and its Subsidiaries
         have (a) reviewed the areas within their businesses and operations
         which could be adversely affected by failure to become "YEAR 2000
         COMPLIANT" (i.e. that computer applications, imbedded microchips and
         other systems used by the Borrower or any of its Subsidiaries, will be
         able properly to recognize and perform properly date-sensitive
         functions involving certain dates prior to and any date after December
         31, 1999), (b) developed a detailed plan and timetable to become Year
         2000 Compliant in a timely manner, and (c) committed adequate resources
         to support the Year 2000 plan of the Borrower and its Subsidiaries.
         Based upon such review, the Borrower reasonably believes that the
         Borrower and its Subsidiaries will become "Year 2000 Compliant" in a
         timely manner except to the extent that failure to do so will not have
         any materially adverse effect on the business or financial condition of
         the Borrower or any of its Subsidiaries.

                  5.21. DISCLOSURE. None of this Loan Agreement or any of the
         other Loan Documents contains any untrue statement of a material fact
         or omits to state a material fact (known to the Borrower or any of its
         Subsidiaries in the case of any document or information not furnished
         by it or any of its Subsidiaries) necessary in order to make the
         statements herein or therein not misleading. There is no fact known to
         the Borrower or any of its Subsidiaries which materially adversely
         affects, or which is reasonably likely in the future to materially
         adversely affect, the business, assets, financial condition or
         prospects of the Borrower or any of its Subsidiaries, exclusive of
         effects resulting from changes in general economic conditions, legal
         standards or regulatory conditions.

                  5.22. NO WITHHOLDING. Neither the Borrower nor any of its
         Subsidiaries is required by the laws of any jurisdiction to make any
         deduction or withholding of any nature whatsoever from any payment to
         be made by the Borrower or its Subsidiaries hereunder or under any Loan
         Document unless disclosed to the Lender in writing prior to the Closing
         Date (which may be in the form of legal opinions) and unless the amount
         and likelihood such deductions or withholdings are not, in the Lender's
         reasonable discretion, material. Neither this Loan Agreement nor any of
         the other Loan Documents is subject to any registration or stamp tax or
         any other similar or like taxes payable in any jurisdiction.


<PAGE>

                  5.23. CHIEF EXECUTIVE OFFICE. The location of the Borrower's
         and each of its Subsidiaries chief executive office or registered
         office, as applicable, is set forth in SCHEDULE 5.23.

                  5.24. INSURANCE. The Borrower and each of its Subsidiaries
         maintain with financially sound and reputable insurers insurance with
         respect to its properties and businesses against such casualties and
         contingencies as are in accordance with sound business practices and
         with the details of such coverage being more fully described on
         SCHEDULE 5.24 hereto.

                  5.25. DELIVERY OF CERTAIN DOCUMENTS. The Borrower has
         delivered to the Lender true and complete copies of all of the
         Bridgestone Acquisition Documents (including all amendments thereto).
         Each of the representations and warranties made by the Borrower and any
         of its Subsidiaries in any of the Bridgestone Acquisition Documents was
         true and correct in all material respects when made and continues to be
         true and correct in all material respects on the Closing Date, except
         to the extent that any of such representations and warranties relate,
         by the express terms thereof, solely to a date falling prior to the
         Closing Date.

         6.  AFFIRMATIVE COVENANTS OF THE BORROWER.

         The Borrower covenants and agrees that, so long as the Loan or Note is
outstanding:

                  6.1. PUNCTUAL PAYMENT. The Borrower will duly and punctually
         pay or cause to be paid the principal and interest on the Loan and the
         fees provided for in this Loan Agreement, all in accordance with the
         terms of this Loan Agreement and the Note.

                  shall continue in effect for more than fourteen (14) days;

                           (n) there shall occur any material damage to, or
                  loss, theft or destruction of, any Collateral, whether or not

                  condemnation, act of God or public enemy, or other casualty,
                  which in any such case causes the cessation or substantial
                  curtailment of revenue producing activities at any facility of
                  the Borrower or any of its Subsidiaries if such event or
                  circumstance is not covered by business interruption insurance
                  and would have in the opinion of the Lender a material adverse
                  effect on the business or financial condition of the Borrower
                  or such Subsidiary;

                           (o) there shall occur the loss, suspension or

                  held or hereafter acquired by the Borrower or any of its
                  Subsidiaries if such loss, suspension, revocation or failure
                  to renew would have in the opinion of the Lender a material
                  adverse effect on the business or financial condition of the
                  Borrower or such Subsidiary; and

                           (p) the Borrower or any of its Subsidiaries shall
                  fail to observe or perform, in any material respect, any
                  covenant, agreement or obligation contained in any of the
                  Merger Documents or the Bridgestone Acquisition Documents;

         then, and in any such event, so long as the same may be continuing, the
         Lender may by notice in writing to the Borrower declare all amounts
         owing with respect to this Loan Agreement, the Note and the other Loan
         Documents to be, and they shall thereupon forthwith become, immediately
         due and payable without presentment, demand, protest or other notice of
         any kind, all of which are hereby expressly waived by the Borrower;
         PROVIDED that in the event of any Event of Default specified in
         Sections 10.1(g), 10.1(h), 10.1(i), all such amounts shall become
         immediately due and payable automatically and without any requirement
         of notice from the Lender.

                  10.2. REMEDIES. In case any one or more of the Events of
         Default shall have occurred and be continuing, and whether or not the
         Lender shall have accelerated the maturity of the Loan pursuant to
         Section 10.1, the Lender, if owed any amount with respect to the Loan,
         may proceed to protect and enforce its rights by suit in equity, action
         at law or other appropriate proceeding, whether for the specific
         performance of any covenant or agreement contained in this Loan
         Agreement and the other Loan Documents or any instrument pursuant to
         which the Obligations to the Lender are evidenced, and, if such amount
         shall have become due, by declaration or otherwise, proceed to enforce
         the payment thereof or any other legal or equitable right of the
         Lender. No remedy herein conferred upon the Lender or the holder of the
         Note is intended to be exclusive of any other remedy and each and every
         remedy shall be cumulative and shall be in addition to every other
         remedy given hereunder or now or hereafter existing at law or in equity
         or by statute or any other provision of law.

                  10.3. DISTRIBUTION OF COLLATERAL PROCEEDS. If following the
         occurrence or during the continuance of any Default or Event of
         Default, the Lender receives any monies in connection with the
         enforcement of any the Security Documents, or otherwise with respect to
         the realization upon any of the Collateral, such monies shall be
         distributed for application as follows:

                           (a) First, to the payment of, or (as the case may be)

                  reasonable costs, expenses, disbursements and losses which
                  shall have been incurred or sustained by the Lender in
                  connection with the collection of such monies by the Lender,
                  for the exercise, protection or enforcement by the Lender of
                  all or any of the rights, remedies, powers and privileges of
                  the Lender under this Loan Agreement or any of the


<PAGE>

                  other Loan Documents or in respect of the Collateral or in
                  support of any provision of adequate indemnity to the Lender
                  against any taxes or liens which by law shall have, or may
                  have, priority over the rights of the Lender to such monies;

                           (b) Second, to all other Obligations in such order or
                  preference as the Lender may determine;

                           (c) Third, the excess, if any, shall be returned to
                  the Borrower or to such other Persons as are entitled thereto.

         11.  SETOFF.

any Event of Default, any deposits or other sums credited by or due from the
Lender to the Borrower and any securities or other property of the Borrower in
the possession of the Lender may be applied to or set off by the Lender against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to the Lender.

                  12.3. SURVIVAL. The covenants contained in this Section 12

                             STOCK OPTION AGREEMENT

         THIS STOCK OPTION AGREEMENT is made and entered into as of November 30,
1999, by and between Optical Security Group, Inc., a Colorado corporation
("ISSUER") and Applied Holographics plc, a public limited company incorporated
and existing under the laws of England and Wales ("GRANTEE").

                                   WITNESSETH:

         WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger of even date herewith (the "MERGER AGREEMENT"), which agreement has been
executed by the parties hereto immediately prior to this Agreement; and

         WHEREAS, as a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined):

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

         1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "OPTION") to purchase, subject to the terms hereof, up to 1,234,283
fully paid and nonassessable shares (the "OPTION SHARES") of Issuer's Common
Stock, par value $0.005 per share ("COMMON STOCK"), at a price of $7.00 per
share (the "OPTION PRICE"); PROVIDED that in no event shall the number of shares
of Common Stock for which this Option is exercisable exceed 19.9% of the
Issuer's issued and outstanding shares of Common Stock without giving effect to
any shares subject to or issued pursuant to the Option. The number of shares of
Common Stock that may be received upon the exercise of the Option and the Option
Price are subject to adjustment as herein set forth.

            (b) In the event that any additional shares of Common Stock are
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement), the number of shares of Common Stock subject
to the Option shall be increased so that, after such issuance, it equals 19.9%
of the number of shares of Common Stock then issued and outstanding without
giving effect to any shares subject to or issued pursuant to the Option. Nothing
contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to
authorize Issuer or Grantee to breach any provision of the Merger Agreement.

         2. (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, and from time to time, if, but only if, both an Initial
Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as
hereinafter defined) shall have occurred prior to the occurrence of an Exercise
Termination Event (as hereinafter defined); PROVIDED THAT the Holder shall have
sent the written notice of such exercise (as provided in subsection (e) of this
Section 2) within ninety (90) days following such Subsequent Triggering Event.
Each of the following shall be an "Exercise Termination Event": (i) the
Effective Time (as defined in the Merger Agreement) of the Merger; (ii)
termination of the Merger Agreement in accordance with the provisions thereof if
such termination occurs prior to the occurrence of an Initial Triggering Event
except a termination by Grantee pursuant to Section 7.01(b)(ii) of the Merger
Agreement; or (iii) the passage of six months after termination of the Merger
Agreement if such termination follows the occurrence of an Initial Triggering
Event or is a termination by Grantee pursuant to Section 7.01(b)(ii) of the
Merger Agreement (provided that if an Initial Triggering Event continues or
occurs beyond such termination and prior to the passage of such six-month
period, the Exercise Termination Event shall be three months from the expiration
of the Last Triggering Event but in no event more than nine months after such
termination). The "Last Triggering Event" shall mean the last Initial Triggering
Event to expire. The term "Holder" shall mean the holder or holders of the
Option.

<PAGE>

         (b) The term "Initial Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:

            (i) Issuer or any of its Subsidiaries (each an "ISSUER SUBSIDIARY"),
without having received Grantee's prior written consent, shall have entered into
an agreement to engage in an Acquisition Transaction (as hereinafter defined)
with any person (the term "person" for purposes of this Agreement having the
meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities
Exchange Act of 1934, as amended (the "1934 ACT"), and the rules and regulations
thereunder) other than Grantee or any of its Subsidiaries (each a "GRANTEE
SUBSIDIARY") or the Board of Directors of Issuer shall have recommended that the
stockholders of Issuer approve or accept any Acquisition Transaction or shall
have failed to publicly oppose an Acquisition Transaction, in each case with any
person other than Grantee or a Grantee Subsidiary. For purposes of this
Agreement, "Acquisition Transaction" shall mean (w) a merger or consolidation,
or any similar transaction, involving Issuer or any Significant Subsidiary (as
defined in Rule 1-02 of Regulation S-X promulgated by the Securities and
Exchange Commission (the "SEC")) of Issuer, (x) a purchase, lease or other
acquisition of all or a substantial portion of the assets of Issuer or any
Significant Subsidiary of Issuer, (y) a purchase or other acquisition (including
by way of merger, consolidation, share exchange or otherwise) of securities
representing 20% or more of the voting power of Issuer or any Significant
Subsidiary of Issuer, or (z) any substantially similar transaction; PROVIDED,
HOWEVER, that in no event shall any merger, consolidation, purchase,
liquidation, dividend in kind, reorganization or similar transaction involving
only the Issuer and one or more of its Subsidiaries or involving only any two or
more of such Subsidiaries, be deemed to be an Acquisition Transaction, so long
as any such transaction is not entered into in violation of the terms of the
Merger Agreement;

            (ii) Issuer or any Issuer Subsidiary, without having received
Grantee's prior written consent, shall have authorized, recommended, proposed or
publicly announced its intention to authorize, recommend or propose to engage
in, an Acquisition Transaction with any person other than Grantee or a Grantee
Subsidiary, or the Board of Directors of Issuer shall have publicly withdrawn or
modified, or publicly announced its intention to withdraw or modify, in any
manner adverse to Grantee, its recommendation that the stockholders of Issuer
approve the transactions contemplated by the Merger Agreement;

            (iii) Issuer terminates the Merger Agreement pursuant to Section
7.01(d) of the Merger Agreement;

            (iv) Any person other than Grantee, any Grantee Subsidiary or
any Issuer Subsidiary acting in a fiduciary capacity in the ordinary course of
its business shall have acquired beneficial ownership or the right to acquire
beneficial ownership of 20% or more of the outstanding shares of Common Stock
(the term "beneficial ownership" for purposes of this Option Agreement having
the meaning assigned thereto in Section 13(d) of the 1934 Act, and the rules and
regulations thereunder);

            (v) Any person other than Grantee or any Grantee Subsidiary
shall have made a bona fide proposal to Issuer or its stockholders by public
announcement or written communication that is or becomes the subject of public
disclosure to engage in an Acquisition Transaction; or

            (vi) After an overture is made by a third party to Issuer or
its stockholders to engage in an Acquisition Transaction, Issuer shall have
breached any covenant or obligation contained in the Merger Agreement and such
breach (x) would entitle Grantee to terminate the Merger Agreement and (y) shall
not have been cured prior to the Notice Date (as defined below).

         (c) The term "Subsequent Triggering Event" shall mean either of the
following events or transactions occurring after the date hereof:

            (i) The acquisition by any person of beneficial ownership of 30% or
more of the then outstanding Common Stock; or

<PAGE>

            (ii) The occurrence of the Initial Triggering Event described
in clause (i) of subsection (b) of this Section 2, except that the percentage
referred to in clause (y) shall be 30%.

         (d) Issuer shall notify Grantee promptly in writing of the occurrence
of any Initial Triggering Event or Subsequent Triggering Event (together, a
"TRIGGERING EVENT"), it being understood that the giving of such notice by
Issuer shall not be a condition to the right of the Holder to exercise the
Option.

         (e) In the event the Holder is entitled to and wishes to exercise the
Option, it shall send to Issuer a written notice (the date of which being herein
referred to as the "NOTICE DATE") specifying (i) the total number of shares it
will purchase pursuant to such exercise and (ii) a place and date not earlier
than three business days nor later than 60 business days from the Notice Date
for the closing of such purchase (the "CLOSING DATE"). Any exercise of the
Option shall be deemed to occur on the Notice Date relating thereto.

         (f) At the closing referred to in subsection (e) of this Section 2, the
Holder shall pay to Issuer the aggregate purchase price for the shares of Common
Stock purchased pursuant to the exercise of the Option in immediately available
funds by wire transfer to a bank account designated by Issuer, PROVIDED that
failure or refusal of Issuer to designate such a bank account shall not preclude
the Holder from exercising the Option.

         (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder, and the Holder
shall deliver to Issuer a copy of this Agreement and a letter agreeing that the
Holder will not offer to sell or otherwise dispose of such shares in violation
of applicable law or the provisions of this Agreement.

         (h) Certificates for Common Stock delivered at a closing hereunder may
be endorsed with a restrictive legend that shall read substantially as follows:

         "The transfer of the shares represented by this certificate
         is subject to certain provisions of an agreement between the
         registered holder hereof and Issuer and to resale
         restrictions arising under the Securities Act of 1933, as
         amended. A copy of such agreement is on file at the principal
         office of Issuer and will be provided to the holder hereof
         without charge upon receipt by Issuer of a written request
         therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 ACT"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

         (i) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (e) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder.


<PAGE>

Issuer shall pay all expenses, and any and all United States federal, state and
local taxes and other charges that may be payable in connection with the
preparation, issue and delivery of stock certificates under this Section 2 in
the name of the Holder or its assignee, transferee or designee.

         3. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) promptly to take all action as may from time to time be required
(including complying with all premerger notification, reporting and waiting
period requirements specified in 15 U.S.C. sec. 18a and regulations promulgated
thereunder necessary before the Option may be exercised, cooperating fully with
the Holder in preparing such applications or notices and providing such
information to the any federal or state regulatory authority as they may
require) in order to permit the Holder to exercise the Option and Issuer duly
and effectively to issue shares of Common Stock pursuant hereto; and (iv)
promptly to take all action provided herein to protect the rights of the Holder
against dilution.

         4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Stock Option
Agreements and related Options for which this Agreement (and the Option granted
hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

         5. In addition to the adjustment in the number of shares of Common
Stock that are purchasable upon exercise of the Option pursuant to Section 1 of
this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5. In the event of any change in, or
distributions in respect of, the Common Stock by reason of stock dividends,
split-ups, mergers, recapitalizations, combinations, subdivisions, conversions,
exchanges of shares, distributions on or in respect of the Common Stock that
would be prohibited under the terms of the Merger Agreement, or the like, the
type and number of shares of Common Stock purchasable upon exercise hereof and
the Option Price shall be appropriately adjusted in such manner as shall fully
preserve the economic benefits provided hereunder and proper provision shall be
made in any agreement governing any such transaction to provide for such proper
adjustment and the full satisfaction of the Issuer's obligations hereunder.

         6. Subject to Section 8 below, upon the occurrence of a Subsequent
Triggering Event that occurs prior to an Exercise Termination Event, Issuer
shall, at the request of Grantee delivered within ninety (90) days after such
Subsequent Triggering Event (whether on its own behalf or on behalf of any
subsequent holder of this Option (or part thereof) or any of the shares of
Common Stock issued pursuant hereto), promptly prepare, file and keep current a
shelf registration statement under the 1933 Act covering the resale of any
shares issued pursuant to this Option and the issuance of any shares issuable
pursuant to this Option to the extent then permitted under the rules,
regulations or policies of the SEC and, to the extent not so permitted, the
resale of such shares issuable pursuant to this Option. The Issuer shall use its
reasonable best efforts to cause such registration statement to become effective
and remain current in order to permit the sale or other disposition of this
Option and any shares of Common Stock issued upon total or partial exercise of
this Option ("OPTION

<PAGE>

SHARES") in accordance with any plan of disposition requested by Grantee. Issuer
will use its reasonable best efforts to cause such registration statement first
to become effective and then to remain effective for such period not in excess
of 180 days from the day such registration statement first becomes effective or
such shorter time as may be reasonably necessary to effect such sales or other
dispositions. Grantee shall have the right to demand two such registrations. The
foregoing notwithstanding, if, at the time of any request by Grantee for
registration of the Option or Option Shares as provided above, Issuer is in
registration with respect to an underwritten public offering of shares of Common
Stock, and if in the good faith judgment of the managing underwriter or managing
underwriters, or, if none, the sole underwriter or underwriters, of such
offering the inclusion of the Holder's Option or Option Shares would interfere
with the successful marketing of the shares of Common Stock offered by Issuer,
the number of Option Shares otherwise to be covered in the registration
statement contemplated hereby may be reduced; and PROVIDED, HOWEVER, that after
any such required reduction the number of Option Shares to be included in such
offering for the account of the Holder shall constitute at least 25% of the
total number of shares to be sold by the Holder and Issuer in the aggregate; and
PROVIDED FURTHER, however, that if such reduction occurs, then the Issuer shall
file a registration statement for the balance as promptly as practical and no
reduction shall thereafter occur. Each such Holder shall provide all information
reasonably requested by Issuer for inclusion in any registration statement to be
filed hereunder. If requested by any such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such shares, but only to the extent of obligating itself in
respect of representations, warranties, indemnities and other agreements
customarily included in such underwriting agreements for the Issuer. Upon
receiving any request under this Section 6 from any Holder, Issuer agrees to
send a copy thereof to any other person known to Issuer to be entitled to
registration rights under this Section 6, in each case by promptly mailing the
same, postage prepaid, to the address of record of the persons entitled to
receive such copies. Notwithstanding anything to the contrary contained herein,
in no event shall Issuer be obligated to effect more than two registrations
pursuant to this Section 6 by reason of the fact that there shall be more than
one Grantee as a result of any assignment or division of this Agreement.

         7. (a) Immediately prior to the occurrence of a Repurchase Event (as
defined below), subject to Section 8 below, (i) following a request of the
Holder, delivered prior to an Exercise Termination Event, Issuer (or any
successor thereto) shall repurchase the Option from the Holder at a price (the
"OPTION REPURCHASE PRICE") equal to the amount by which (A) the market/offer
price (as defined below) exceeds (B) the Option Price, multiplied by the number
of shares for which this Option may then be exercised and (ii) at the request of
the owner of Option Shares from time to time (the "OWNER") delivered within
ninety (90) days after such occurrence (or such later period as provided in
Section 10), Issuer shall repurchase such number of the Option Shares from the
Owner as the Owner shall designate at a price (the "OPTION SHARE REPURCHASE
PRICE") equal to the market/offer price multiplied by the number of Option
Shares so designated. The term "market/offer price" shall mean the highest of
(i) the price per share of Common Stock at which a tender offer or exchange
offer therefor has been made, (ii) the price per share of Common Stock to be
paid by any third party pursuant to an agreement with Issuer, (iii) the highest
closing price for shares of Common Stock within the six-month period immediately
preceding the date the Holder gives notice of the required repurchase of this
Option or the Owner gives notice of the required repurchase of Option Shares, as
the case may be, or (iv) in the event of a sale of all or a substantial portion
of Issuer's assets, the sum of the price paid in such sale for such assets and
the current market value of the remaining assets of Issuer as determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, divided by the number of shares of Common Stock of
Issuer outstanding at the time of such sale. In determining the market/offer
price, the value of consideration other than cash shall be determined by a
nationally recognized investment banking firm selected by the Holder or Owner,
as the case may be, and reasonably acceptable to the Issuer.

            (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. Within the later to occur of (x) five business days after the
surrender of the Option and/or certificates

<PAGE>

representing Option Shares and the receipt of such notice or notices relating
thereto and (y) the time that is immediately prior to the occurrence of a
Repurchase Event, Issuer shall deliver or cause to be delivered to the Holder
the Option Repurchase Price and/or to the Owner the Option Share Repurchase
Price therefor or the portion thereof that Issuer is not then prohibited under
applicable law and regulation from so delivering.

            (c) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of all or a substantial portion of the assets of Issuer, other
than any such transaction which would not constitute an Acquisition Transaction
pursuant to the proviso to Section 2 (b) (i) hereof or (ii) upon the acquisition
by any person of beneficial ownership of 50% or more of the then outstanding
shares of Common Stock. The parties hereto agree that Issuer's obligations to
repurchase the Option or Option Shares under this Section 7 shall not terminate
upon the occurrence of an Exercise Termination Event unless no Subsequent
Triggering Event shall have occurred prior to the occurrence of an Exercise
Termination Event.

         8. (a) Notwithstanding the terms of Sections 6 and 7 to the
contrary, in the event that Grantee notifies Issuer, after Grantee becomes
entitled to do so under Section 6, that Grantee is exercising its right to
require Issuer to cause the Option Shares to be registered under the 1933 Act
pursuant to Section 6 above, at Issuer's option, Issuer may elect (i) to cause
the Option Shares to be registered under the 1933 Act pursuant to Section 6
above or (ii) to repurchase the Option or the Option Shares by paying to the
Grantee the Option Repurchase Price or Option Share Repurchase Price pursuant to
Section 7(b) notwithstanding the fact that a Repurchase Event shall not have
occurred as of the date Grantee requests that Issuer register the Option Shares.
To the extent that, prior to a Repurchase Event, the Grantee has requested, and
the Issuer has agreed, to cause the Option Shares to be registered under the
1933 Act pursuant to Section 6 above, the Grantee shall not be entitled to
exercise its rights to cause Issuer to repurchase the Option or the Option
Shares pursuant to Section 7 hereof.

            (b) Notwithstanding the terms of Sections 6 and 7 to the
contrary, in the event that the Holder or the Owner, as the case may be,
notifies Issuer, after the Holder or the Owner, as the case may be, becomes
entitled to do so under Section 7, that such Holder or Owner is exercising its
right to require Issuer to repurchase the Option and any Option Shares pursuant
to Section 7 hereof, at Issuer's option, Issuer may elect (i) to repurchase the
Option or the Option Shares by paying to such Holder or Owner the Option
Repurchase Price or Option Share Repurchase Price pursuant to Section 7(b), or
(ii) to cause the Option Shares to be registered under the 1933 Act pursuant to
Section 6 above. It is further understood and agreed that, to the extent that
the Issuer has elected pursuant to this Section 8 not to repurchase the Option
or the Option Shares, the Holder or the Owner, as the case may be, shall be
entitled to exercise its rights under Section 6 hereof without limitation
(except as otherwise set forth in such Section 6).

            (c) It is understood and agreed by the parties hereto that
Grantee shall not be entitled to exercise its rights under both Sections 6 and 7
hereof.

         9. (a) Notwithstanding any other provision of this Agreement,
this Option may not be exercised for a number of shares as would, as of the date
of exercise, result in a Notional Total Profit (as defined below) of more than
$1.5 million; PROVIDED THAT nothing in this sentence shall restrict any exercise
of the Option permitted hereby on any subsequent date..

                          FORM OF STOCKHOLDER AGREEMENT

         THIS STOCKHOLDER AGREEMENT (this "AGREEMENT") is made and entered into
as of            , 1999, by and between Applied Holographics plc, a public

         Consummation by Stockholder of the transactions contemplated hereby
         will not violate, or require any consent, approval, or notice under,

         encumbrances whatsoever, except for any such encumbrances or proxies
         arising hereunder.

                  (d) No broker, investment banker, financial adviser or other
         person is entitled to any broker's, finder's, financial adviser's or
         other similar fee or commission in connection with the transactions
         contemplated hereby based upon arrangements made by or on behalf of
         Stockholder.

         or in any other circumstances upon which a vote, consent or other
         approval with respect to the Merger and the Merger Agreement is sought
         (the "STOCKHOLDERS' MEETING"), Stockholder shall vote (or cause to be
         voted) the Stockholder's Shares in favor of the Merger, the execution
         and delivery by Seller of the Merger Agreement, and the approval of the
         terms thereof and each of the other transactions contemplated by the
         Merger Agreement.

                  (b) While this Agreement shall be in effect, at any meeting of

         Seller's Articles of Organization or Bylaws or other proposal or

         or other proposal or transaction would in any manner impede, frustrate,
         prevent or nullify the Merger, the Merger Agreement or any of the other
         transactions contemplated by the Merger Agreement (each of the
         foregoing in clause (i) or (ii) above, a "COMPETING TRANSACTION").

         3. COVENANTS. Stockholder agrees with, and covenants to, Buyer that,

transfer of, any or all of the Stockholder's Shares or any interest therein,
except pursuant to the Merger; (ii) enter into any contract, option or other
agreement or understanding with respect to any transfer of any or all of the
Stockholder's Shares or any interest therein; (iii) grant any proxy, power of

voting agreement or arrangement with respect to such shares; (v) initiate,

Proposal or Superior Proposal, engage in negotiations with or discussions with,
or provide any information or data to, any person or entity (other than Buyer,
any of its affiliates or representatives) relating to any Acquisition Proposal
or Superior Proposal; PROVIDED, THAT Stockholder may transfer (as defined above)
any of the Stockholder's Shares to any other person or entity who is on the date
hereof, or to any family member of a person or to any charitable institution
which prior to the Stockholders Meeting and prior to such transfer becomes, a
party to this Agreement bound by all the obligations of "Stockholder" hereunder.

         4. GRANT OF IRREVOCABLE PROXY; APPOINTMENT OF PROXY.

                  (a) Stockholder hereby irrevocably grants to, and appoints,
         Buyer and David Tidmarsh, Chief Executive of Buyer, and Mike Angus,
         Group Finance Director of Buyer, in their respective capacities as
         officers of Buyer, and any individual who shall hereafter succeed to
         any such office of Buyer, and each of them individually, Stockholder's
         proxy and attorney-in-fact (with full power of substitution), for and
         in the name, place and stead of Stockholder, to vote the Stockholder's
         Shares, or grant a consent or approval in respect of the Stockholder's
         Shares (i) in favor of the Merger, the execution and delivery of the
         Merger Agreement and approval of the terms thereof and each of the
         other transactions contemplated by the Merger Agreement, and (ii)
         against any Competing Transaction.


<PAGE>

                  (b) Stockholder represents that any proxies heretofore given
         in respect of the Stockholder's Shares are not irrevocable, and that
         any such proxies are hereby revoked.

                  (c) Stockholder hereby affirms that the irrevocable proxy set
         forth in this Section 4 is given in connection with the execution of
         the Merger Agreement, that such irrevocable proxy is given to secure
         the performance of the duties of Stockholder under this Agreement and
         that such irrevocable proxy will continue in force and effect while
         this Agreement is in effect. Stockholder hereby further affirms that
         the irrevocable proxy is coupled with an interest sufficient in law to
         support an irrevocable power and may under no circumstances be revoked.
         Stockholder hereby ratifies and confirms all that such irrevocable
         proxy may lawfully do or cause to be done by virtue hereof. Such
         irrevocable proxy is executed and intended to be irrevocable in
         accordance with the Colorado Business Corporation Act.

         5. AGREEMENT TO TENDER STOCKHOLDER'S SHARES. Stockholder covenants and
agrees to promptly accept the all cash offer of $7.00 per share to purchase each
of Stockholder's Shares made by Buyer or Newco in accordance with the Offer and
Stockholder further agrees not to withdraw such acceptance, so long as either
(i) the holders of more than 50% of the outstanding shares of Seller Common
Stock have agreed to accept the cash offer in accordance with the Offer, or (ii)
neither Buyer nor Newco has terminated the Offer without the purchase by Buyer
or Newco of shares of Seller Common Stock or permitted the Offer to lapse in
accordance with its terms. For the avoidance of doubt, for purposes of
determining whether the condition in subclause (i) of this Section is satisfied,
the Stockholder's Shares shall be included in the shares, the holders of which
have accepted the cash offer in accordance with the Offer.

         6. CERTAIN EVENTS. Stockholder agrees that this Agreement and the
obligations hereunder shall attach to the Stockholder's Shares and shall be
binding upon any person or entity to which legal or beneficial ownership of any
or all of the Stockholder's Shares shall pass, whether by operation of law or
otherwise, including without limitation Stockholder's successors or assigns. In
the event of any stock split, stock dividend, merger, reorganization,
recapitalization or other change in the capital structure of Seller affecting
Seller Common Stock, or the acquisition of additional shares of Seller Common
Stock or other voting securities of Seller by Stockholder, the number of the
Stockholder's Shares subject to the terms of this Agreement shall be adjusted
appropriately and this Agreement and the obligations hereunder shall attach to
any additional shares of Seller Common Stock or other voting securities of
Seller issued to or acquired by Stockholder.

         7. LEGEND Stockholder agrees that at the request of Buyer, Stockholder
will place a legend, referring to this Agreement and in a form reasonably
satisfactory to Buyer, on the certificates representing such Stockholder's
Shares.

         8. FURTHER ASSURANCES. Stockholder shall, upon request of Buyer,
execute and deliver any additional documents and take such further actions as
may reasonably be deemed by Buyer to be necessary or desirable to carry out the
provisions hereof and to vest the power to vote the Stockholder's Shares as
contemplated by Section 4 in Buyer and the other irrevocable proxies described
therein at the expense of Buyer.

         9. TERMINATION. This Agreement, and all rights and obligations of the
parties hereunder, shall terminate upon the earlier of (a) termination of the
Merger Agreement in accordance with its terms or (b) upon consummation of the
Merger (as defined in the Merger Agreement).

         10. ENFORCEMENT COSTS. If any party institutes an action for the
enforcement of this Agreement, the prevailing party shall be entitled to
reimbursement on demand of all costs and expenses of such action including
reasonable legal fees.

         11. MISCELLANEOUS.

                  (a) Capitalized terms used and not otherwise defined in this
         Agreement shall have the


<PAGE>

         respective meanings assigned to them in the Merger Agreement.

                  (b) All notices, requests, claims, demands and other
         communications under this Agreement shall be in writing and shall be
         deemed given if delivered personally or sent by overnight courier
         (providing proof of delivery) to the parties at the following addresses
         (or at such other address for a party as shall be specified by like
         notice): (i) if to Buyer, to the address provided in the Merger
         Agreement; and (ii) if to Stockholder, to its address shown below its
         signature on the last page hereof.

                  (c) The headings contained in this Agreement are for reference
         purposes only and shall not affect in any way the meaning or
         interpretation of this Agreement.

                  (d) This Agreement may be executed in two or more
         counterparts, each of which shall be considered an original hereof and
         one and the same agreement.

                  (e) This Agreement (including the documents and instruments
         referred to herein) constitutes the entire agreement, and supersedes
         all prior agreements and understandings, both written and oral, among
         the parties with respect to the subject matter hereof.

                  (f) This Agreement shall be governed by, and construed in
         accordance with, the laws of the State of Colorado, regardless of the
         laws that might otherwise govern under applicable principles of
         conflicts of laws thereof.

                  (g) Neither this Agreement nor any of the rights, interests or
         obligations under this Agreement shall be assigned, in whole or in
         part, by operation of law or otherwise, by any of the parties without
         the prior written consent of the other parties, except as expressly
         contemplated by the proviso to Section 3(b). Any assignment in
         violation of the foregoing shall be void.

                  (h) Stockholder agrees that irreparable damage would occur and
         that Buyer would not have any adequate remedy at law in the event that
         any of the provisions of this Agreement were not performed in
         accordance with their specific terms or were otherwise breached. It is
         accordingly agreed that Buyer shall be entitled to an injunction or
         injunctions to prevent breaches by Stockholder of this Agreement and to
         enforce specifically the terms and provisions of this Agreement in any
         court, this being in addition to any other remedy to which they are
         entitled at law or in equity. In addition, each of the parties hereto
         (i) consents to submit such party to the personal jurisdiction of any
         Federal court located in the State of Colorado or any State of Colorado
         state court in the event any dispute arises out of this Agreement or
         any of the transactions contemplated hereby, (ii) agrees that such
         party will not attempt to deny or defeat such personal jurisdiction by
         motion or other request for leave from any such court and (iii) agrees
         that such party will not bring any action relating to this Agreement or
         any of the transactions contemplated hereby in any court other than a
         Federal court sitting in the State of Colorado or a Colorado state
         court. The foregoing remedies are in addition to, and not in lieu of,
         any payment required to be made by Seller pursuant to the terms of the
         Merger Agreement.

                  (i) If any term, provision, covenant or restriction herein, or
         the application thereof to any circumstance, shall, to any extent, be
         held by a court of competent jurisdiction to be invalid, void or
         unenforceable, the remainder of the terms, provisions, covenants and
         restrictions herein and the application thereof to any other
         circumstances, shall remain in full force and effect, shall not in any
         way be affected, impaired or invalidated, and shall be enforced to the
         fullest extent permitted by law.

                  (j) No amendment, modification or waiver in respect of this
         Agreement shall be effective against any party unless it shall be in
         writing and signed by such party.
