To the Holders of Common Stock
  of New Image Industries, Inc.:
 
INTRODUCTION
 
     Image Acquisition Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of DENTSPLY International Inc., a Delaware corporation
("Parent"), hereby offers to purchase all outstanding shares of common stock,
par value $.001 per share (the "Shares" and, each, a "Share"), of New Image
Industries, Inc., a Delaware corporation (the "Company"), at a price of $2.00
per Share (the "Offer Price"), net to the seller in cash, without interest, upon
the terms and subject to the conditions set forth in this Offer to Purchase and
in the related Letter of Transmittal (which, together with any amendments or
supplements hereto or thereto, collectively constitute the "Offer").
 
     Tendering stockholders will not be charged 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. The Purchaser will pay
all fees and expenses of Robert W. Baird & Co. Incorporated, which is acting as
Dealer Manager (the "Dealer Manager"), Harris Trust and Savings Bank, which is
acting as the Depositary (the "Depositary"), and D.F. King & Co., Inc., which is
acting as Information Agent (the "Information Agent"), incurred in connection
with the Offer. See Section 17.
 
     THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT THE OFFER AND THE
MERGER (AS DEFINED BELOW) ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY
AND ITS STOCKHOLDERS, HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT (AS DEFINED
BELOW) AND THE TRANSACTIONS CONTEMPLATED THEREBY AND UNANIMOUSLY RECOMMENDS THAT
ALL HOLDERS OF SHARES TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
     CLEARY GULL REILAND & MCDEVITT INC. ("CLEARY GULL"), THE COMPANY'S
FINANCIAL ADVISOR, HAS DELIVERED TO THE BOARD OF DIRECTORS OF THE COMPANY ITS
WRITTEN OPINION DATED JANUARY 20, 1997, TO THE EFFECT THAT THE CONSIDERATION TO
BE RECEIVED BY HOLDERS OF SHARES IN EACH OF THE OFFER AND THE MERGER IS FAIR,
FROM A FINANCIAL POINT OF VIEW, TO SUCH HOLDERS AS OF THE DATE OF DELIVERY OF
SUCH OPINION. SUCH 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 ACCOMPANIES THIS OFFER TO PURCHASE. CLEARY GULL HAS PREVIOUSLY PROVIDED
INVESTMENT BANKING AND FINANCIAL ADVISORY SERVICES TO PARENT. SEE SECTION 11.
 
     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION DATE (AS DEFINED IN SECTION
1) THAT NUMBER OF SHARES WHICH REPRESENTS AT LEAST FIFTY-FIVE PERCENT (55%) OF
ALL OUTSTANDING SHARES AS OF THE DATE OF COMMENCEMENT OF THE OFFER (THE "MINIMUM
TENDER CONDITION"). SEE SECTIONS 1 AND 15.
 
     The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of January 27, 1997 (the "Merger Agreement"), by and 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 (the "Merger"), the separate existence of
the Purchaser (except as may be continued by operation of law) will cease, and
the Company will continue as the surviving corporation following the Merger (the
"Surviving Corporation"). At the Effective Time of the Merger (the "Effective
Time"), each outstanding Share (other than Shares held in the treasury of the
Company or owned by Parent or any direct or indirect subsidiary of Parent
(including the Purchaser) or by stockholders, if any, who are entitled to and
who properly exercise appraisal rights under the Delaware General Corporation
Law (the "DGCL")) will be converted into the right to receive the Offer Price in
cash, without interest (the "Merger Consideration").
 
     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 Minimum Tender Condition is satisfied and the Purchaser accepts for payment
Shares tendered pursuant to the Offer, the Purchaser will be entitled to
designate all of the members of the Company's Board of Directors and to effect
the Merger without the affirmative vote of any other stockholder of the Company.
In the event the Purchaser acquires 90% or more of the Shares pursuant to
<PAGE>   13
 
the Offer, the Purchaser would be able to effect the Merger pursuant to the
short-form merger provisions of the DGCL, without prior notice to, or any action
by, any other stockholder of the Company. See Section 12.
 
     The Merger Agreement provides that, following the satisfaction or waiver of
the conditions of the Offer, the Purchaser will accept for payment, in
accordance with the terms of the Offer, all Shares validly tendered (and not
previously withdrawn) pursuant to the Offer as promptly as practicable following
the termination of the Offer, which is currently 12:00 Midnight, New York City
time, on Monday, March 3, 1997. The Merger Agreement provides that the Purchaser
may, under certain circumstances and from time to time, extend the period of
time during which the Offer is open. Also at the Effective Time, each option and
warrant to purchase Shares, whether or not then exercisable in accordance with
its terms, will be converted into the right to receive, upon the surrender of
the agreement evidencing such option or warrant and the delivery of an
acknowledgment in accordance with the terms of the Merger Agreement, an amount
in cash (net of applicable withholding) equal to the excess, if any, of the
Offer Price over the exercise price per Share subject to such option or warrant,
as the case may be, multiplied by the number of Shares previously subject to
such option or warrant. See Section 13.
 
     The Purchaser and Parent have also entered into separate stockholder
agreements (the "Stockholder Agreements") with (i) each executive officer and
director of the Company who, in each case, beneficially owns Shares or options
or warrants to purchase Shares and (ii) The William W. Stevens and Virda J.
Stevens Trust, a stockholder of the Company (collectively, the "Stockholder
Parties"), pursuant to which such Stockholder Parties have agreed to tender all
Shares held by such Stockholder Parties into the Offer. Such Stockholder Parties
presently hold 537,795 Shares, or approximately 9.8% of the outstanding Shares.
In addition, Parent, the Company and Dewey F. Edmunds, the Company's current
President and Chief Executive Officer, will enter into an employment agreement
(the "Employment Agreement"), pursuant to which, subject to certain conditions,
Mr. Edmunds will be employed as Vice President and General Manager of the
Company following the purchase of Shares pursuant to the Offer. See Section 13.
 
     The Company has represented and warranted to Parent and the Purchaser that,
as of January 27, 1997, there were 5,479,911 Shares issued and outstanding.
Accordingly, approximately 3,013,951 Shares constitute fifty-five percent (55%)
of the Shares outstanding as of the date of the commencement of the Offer.
 
     The Purchaser and Parent estimate that the total funds required to purchase
all Shares validly tendered pursuant to the Offer, to consummate the Merger and
to pay all related costs and expenses will be approximately $12 million. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution or intercompany loan which will be made by Parent to the
Purchaser. Parent plans to obtain funds for such capital contribution or
intercompany loan from its available sources of cash, including its cash on
hand, its revolving loan facility or short-term bank borrowings.
 
     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 as they may affect stockholders are described in Section 5.
 
1. TERMS OF THE OFFER.
 
     Upon the terms and subject to the conditions of the Offer, the Purchaser
will accept for payment and pay for all Shares validly tendered prior to the
Expiration Date and not theretofore withdrawn. The term "Expiration Date" means
12:00 Midnight, New York City time, on March 3, 1997, 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 the applicable regulations of the Securities and Exchange
Commission (the "Commission"), the Purchaser also expressly reserves the right
(subject to the provisions of the Merger Agreement), 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 15 hereof shall have occurred or shall have been determined
by the Purchaser to have occurred, to (i) extend the period of time during which
the Offer is open, and thereby delay acceptance for payment, and payment for,
Shares, by giving oral or written notice to the Depositary, and (ii) amend the
Offer in any other
 
                                        2
<PAGE>   14
 
respect by giving oral or written notice of such amendment to the Depositary and
by making a public announcement thereof. 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.
 
     If by 12:00 Midnight, New York City time, on Monday, March 3, 1997 (or any
other date or time then set as the Expiration Date), any or all conditions of
the Offer have not been satisfied or waived, the Purchaser reserves the right
(but shall not be obligated), upon the terms and subject to the conditions
contained in the Merger Agreement and to the applicable rules and regulations of
the Commission, to (i) terminate the Offer and not accept for payment any Shares
and return all tendered Shares to tendering stockholders, (ii) waive all 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, (iii) 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 (iv) amend the Offer. Under the terms of the Merger Agreement,
Parent may not, and will cause the Purchaser not to, without the prior written
consent of the Company, decrease the Offer Price, or change the form of
consideration payable, in the Offer, decrease the number of Shares sought in the
Offer, change the conditions of the Offer from those contained in the Appendix
to the Merger Agreement, impose additional conditions to the Offer, or amend any
material term of the Offer in a manner adverse to the holders of Shares.
 
     Any extension, amendment or termination of the Offer will be followed as
promptly as practicable by public announcement. In the case of an extension,
Rule 14e-1(d) under the Securities Exchange Act of 1934, as amended (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 will not have any obligation to
publish, advertise or otherwise communicate any such public announcement other
than by making a release to the Dow Jones News Service.
 
     If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including a waiver of the Minimum Tender Condition), the Purchaser will
disseminate additional tender offer materials and extend the Offer to the extent
required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. The
minimum period during which 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
ten business days is generally required to allow for adequate dissemination to
stockholders and investor response.
 
     Consummation of the Offer is conditioned upon satisfaction of the Minimum
Tender Condition, the expiration or termination of all waiting periods imposed
by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
regulations thereunder (the "HSR Act") and the other conditions set forth in
Section 15. Upon the terms and subject to the conditions contained in the Merger
Agreement, the Purchaser reserves the right (but shall not be obligated) to
waive any or all such conditions. However, if the Purchaser waives or amends the
Minimum Tender Condition during the last five business days during which the
Offer is open, the Purchaser will be required to extend the Expiration Date so
that the Offer will remain open for at least five business days after the
announcement of such waiver or amendment is first published, sent or given to
holders of Shares.
 
     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 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
 
                                        3
<PAGE>   15
 
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 validly to tender Shares pursuant to the
Offer, either (i) a properly completed and duly executed Letter of Transmittal
(or manually signed facsimile thereof), together with any required signature
guarantees and any other required documents, must be received by the Depositary
at one of its addresses set forth on the back cover of this Offer to Purchase
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 below) received by the Depositary), in each case prior
to the Expiration Date, or (ii) the tendering stockholder must comply with the
guaranteed delivery procedure described below.
 
     The Depositary will establish an account with respect to the Shares at The
Depository Trust Company and the Philadelphia Depository Trust Company (each a
"Book-Entry Transfer Facility" and, together, the "Book-Entry Transfer
Facilities") 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
any of the Book-Entry Transfer Facilities' systems may make book-entry delivery
of Shares by causing a Book-Entry Transfer Facility to transfer such Shares into
the Depositary's account in accordance with such 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 a
Book-Entry Transfer Facility, the Letter of Transmittal (or manually signed
facsimile thereof), properly completed and duly executed, with any required
signature guarantees 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 a Book-Entry Transfer Facility as described above is
referred to herein as a "Book-Entry Confirmation." Delivery of documents to a
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures does not constitute delivery to the Depositary.
 
     The method of delivery of Shares, the Letter of Transmittal and all other
required documents is at the election and risk of the tendering stockholder. If
delivery is by mail, registered mail with return receipt requested, properly
insured, is recommended. In all cases, sufficient time should be allowed to
ensure timely delivery.
 
     Signature Guarantees.  No signature guarantee is required on the Letter of
Transmittal if (i) the Letter of Transmittal is signed by the registered holder
of Shares (which term, for purposes of this Section, includes any participant in
any of the Book-Entry Transfer Facilities' systems whose name appears on a
security position listing as the owner of the Shares) tendered therewith and
such registered holder has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on the
Letter of Transmittal or (ii) such Shares are tendered for the account of a firm
that is a member of a registered national securities exchange or of the National
Association of Securities Dealers, Inc. (the "NASD"), or a commercial bank or
trust company having an office or correspondent in the United States or by any
other "eligible guarantor institution," as such term is defined in Rule 17Ad-15
under the Exchange Act (each, an "Eligible Institution"). In all other cases,
all signatures on the Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instructions 1 and 5 to the Letter of Transmittal. If the
certificates for Shares are registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made or certificates
for Shares not tendered or not accepted for payment are to be 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.
 
                                        4
<PAGE>   16
 
     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 procedure 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:
 
          (a) such tender is made by or through an Eligible Institution;
 
          (b) a properly completed and duly executed Notice of Guaranteed
     Delivery substantially in the form provided by the Purchaser is received by
     the Depositary, as provided below, prior to the Expiration Date; and
 
          (c) the certificates for all tendered Shares, in proper form for
     transfer (or a Book-Entry Confirmation with respect to such Shares),
     together with a properly completed and duly executed Letter of Transmittal
     (or manually signed facsimile thereof), with any required signature
     guarantees 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 telegram, facsimile transmission or mail to the
Depositary and must include a guarantee by an Eligible Institution in the form
set forth in such Notice of Guaranteed Delivery.
 
     Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (i) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (ii) a Letter of Transmittal (or
manually signed facsimile thereof), properly completed and duly executed, with
any required signature guarantees, and (iii) 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.
 
     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 as set forth above, 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 the date of this Offer to Purchase. 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 appointment, all prior powers of attorney and proxies 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 and
proxies may be given (and, if given, will not be deemed effective). The
designees of the Purchaser will thereby be empowered to exercise all voting and
other rights with respect to such Shares or other securities or rights in
respect of any annual, special or adjourned meeting of the Company's
stockholders, or otherwise, as they in their sole discretion deem proper. The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser must be able to exercise full voting and other rights
with respect to such Shares and other securities or rights, including voting at
any meeting of stockholders then or thereafter 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 which may, in the
 
                                        5
<PAGE>   17
 
opinion of the Purchaser's counsel, 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, the Dealer Manager or any other person will be under any duty to give
notification of any defects or irregularities in tenders or incur any liability
for failure to give any such notification. The Purchaser's interpretation of the
terms and conditions of the Offer (including the Letter of Transmittal and the
instructions thereto) will be final and binding.
 
     Backup Withholding.  In order to avoid "backup withholding" of federal
income tax on payments of cash pursuant to the Offer, a stockholder surrendering
Shares in the Offer must provide the Depositary with such stockholder's correct
taxpayer identification number ("TIN") on a Substitute Form W-9 and certify
under penalties of perjury that such TIN is correct and that such stockholder is
not subject to backup withholding. Certain stockholders (including, among
others, all corporations and certain foreign individuals and entities) are 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 proved
in a manner satisfactory to the Purchaser and the Depositary). Noncorporate
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 Instruction 9 to the
Letter of Transmittal.
 
3. WITHDRAWAL RIGHTS.
 
     Except as otherwise provided in this Section 3, tenders of Shares are
irrevocable. Shares tendered pursuant to the Offer may be withdrawn pursuant to
the procedures set forth below at any time prior to the Expiration Date and,
unless theretofore accepted for payment and paid for by the Purchaser pursuant
to the Offer, may also be withdrawn at any time after April 1, 1997.
 
     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase and
must specify the name of the person having tendered the Shares to be withdrawn,
the number of Shares to be withdrawn and the name of the registered holder of
the Shares to be withdrawn, if different from the name of the person who
tendered the Shares. If certificates for Shares have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been tendered by an Eligible
Institution, the signatures on the notice of withdrawal must be guaranteed by an
Eligible Institution. If Shares have been delivered pursuant to the procedure
for book-entry transfer as set forth in Section 2, any notice of withdrawal must
also specify the name and number of the account at the appropriate Book-Entry
Transfer Facility to be credited with the withdrawn Shares and otherwise comply
with such Book-Entry Transfer Facility's procedures. Withdrawals of tenders of
Shares may not be rescinded, and any Shares properly withdrawn will thereafter
be deemed not validly tendered for purposes of the Offer. However, withdrawn
Shares may be retendered by again following one of the procedures described in
Section 2 at any time prior to the Expiration Date.
 
     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Parent, the Depositary, the Information Agent, the Dealer Manager or
any other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

4. ACCEPTANCE FOR PAYMENT AND PAYMENT.
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and will pay for all Shares
validly tendered prior to the Expiration Date (and not properly withdrawn in
accordance with Section 3) promptly after the Expiration Date. Any determination
concerning the satisfaction of such terms and conditions will be within the sole
discretion of the Purchaser, subject to rules and regulations of the Commission,
and such determination will be final and binding on all tendering stockholders.
The Purchaser expressly reserves the right, in its sole discretion, to delay
acceptance for payment of or payment for Shares in order to comply in whole or
in part with any applicable law, including, without limitation, the HSR Act. 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).
 
     Parent filed a Notification and Report Form with respect to the Offer under
the HSR Act on January 29, 1997. The waiting period under the HSR Act with
respect to the Offer will expire at 11:59 p.m., New York City time, on February
13, 1997, unless early termination of the waiting period is granted. In
addition, the Antitrust Division of the Department of Justice (the "Antitrust
Division") or the Federal Trade Commission (the "FTC") may extend the waiting
period by requesting additional information or documentary material from Parent.
If such a request is made, such waiting period will expire at 11:59 p.m., New
York City time, on the tenth calendar day following the date of substantial
compliance with such request. See Section 16 hereof for additional information
concerning the HSR Act and the applicability of the antitrust laws to 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 (i) certificates for
such Shares (or timely Book-Entry Confirmation of a transfer of such Shares as
described in Section 2), (ii) a Letter of Transmittal (or manually signed
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and (iii) 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.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not withdrawn as, if and when the Purchaser gives oral or written notice to
the Depositary of the Purchaser's acceptance for payment of such Shares. 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 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, and such Shares may not be withdrawn except to the extent
tendering stockholders are entitled to exercise, and duly exercise, withdrawal
rights as described in Section 3.
 
     If any tendered Shares are not purchased pursuant to the Offer 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 a Book-Entry Transfer Facility pursuant to the procedure set forth in
Section 2, such Shares will be credited to an account maintained at the
appropriate Book-Entry Transfer Facility), as promptly as practicable after the
expiration or termination of the Offer.
 
                                        7
<PAGE>   19
 
     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, but any such transfer or assignment will not relieve the Purchaser of
its obligations under the Offer and will in no way prejudice the rights of
tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.
 
5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
     Sales of Shares pursuant to the Offer (and the receipt of the right to
receive cash by stockholders of the Company pursuant to the Merger) will be
taxable transactions for federal income tax purposes under the Internal Revenue
Code of 1986, as amended (the "Code"), and may also be taxable transactions
under applicable state, local, foreign and other tax laws. For federal income
tax purposes, a tendering stockholder will generally recognize gain or loss
equal to the difference between the amount of cash received by the stockholder
pursuant to the Offer (or to be received pursuant to the Merger) and the
aggregate tax basis in the Shares tendered by the stockholder and purchased
pursuant to the Offer (or canceled pursuant to the Merger). Under present law,
gain or loss will be calculated separately for each block of Shares tendered and
purchased pursuant to the Offer.
 
     If tendered Shares are held by a tendering stockholder as capital assets,
gain or loss recognized by the tendering stockholder will be capital gain or
loss, which will be long-term capital gain or loss if the tendering
stockholder's holding period for the Shares exceeds one year. Under present law,
long-term capital gains recognized by a tendering individual stockholder will
generally be taxed at a maximum federal marginal tax rate of 28%, and long-term
capital gains recognized by a tendering corporate stockholder will be taxed at a
maximum federal marginal tax rate of 35%.
 
     A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals) that tenders Shares
may be subject to 31% backup withholding unless the stockholder provides its TIN
and certifies that such number is correct or properly certifies that it is
awaiting a TIN. A stockholder that does not furnish its TIN may be subject to a
penalty imposed by the IRS. 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 its individual circumstances. Holders of Shares are
urged to consult their own tax advisors to determine the particular tax
consequences to them (including the application and effect of any state, local
or foreign income and other tax laws) of the Offer and the Merger.
 
6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES.
 
     The Shares were traded on the Nasdaq National Market until December 5,
1996. Effective on December 5, 1996, the Shares were delisted from the Nasdaq
National Market. Since being delisted from the Nasdaq National Market, the
Shares have traded on the OTC Bulletin Board.
 
     The following table sets forth, for each of the indicated periods of the
Company's fiscal years ended June 30, 1994, 1995 and 1996, the fiscal quarter
ended September 30, 1996 and the second fiscal quarter

</TABLE>
 
     From the time period beginning on December 6, 1996 and ending on January
30, 1997,the range of the high and low last reported sales prices per Share as
reported on the OTC Bulletin Board has been $1 13/16 to $ 9/16. On December 23,
1996, the last full day of trading prior to the public announcement of the
Letter of Intent (as defined below) between the Company and Parent, the closing
per Share sales price on the OTC Bulletin Board was $1.00. On January 30, 1997,
the last full trading day prior to commencement of the Offer, the closing per
Share sales price on the OTC Bulletin Board was $1 13/16. Stockholders are urged
to obtain a current quotation for their Shares.
 
     As reported by the Company, the Company has never paid any dividends on the
Shares.
 
7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, NASDAQ STOCK QUOTATION AND
   EXCHANGE ACT REGISTRATION.
 
     The Shares were previously traded on the Nasdaq National Market. The Shares
were delisted from the Nasdaq National Market on December 5, 1996 for failure to
meet the capital and surplus requirements set forth in the marketplace rules of
The Nasdaq Stock Market, Inc. Since being delisted from the Nasdaq National
Market, the Shares have traded on the OTC Bulletin Board.
 
     Under the rules of The Nasdaq Stock Market, Inc., an issuer of securities
which has been delisted may again become eligible for listing on The Nasdaq
Stock Market ("Nasdaq") only if it satisfies the Nasdaq's quantitative
designation criteria for initial inclusion, including the requirements that an
issuer have capital and surplus of at least $2 million and have at least 100,000
publicly held shares with a market value of at least $1 million held by at least
300 stockholders. Shares held directly or indirectly by an officer or director
of the Company, or by any beneficial owner of more than 10% of the shares, will
not be considered as being publicly held for this purpose. There can be no
assurance that the Company will in the future satisfy the requirement that the
Company have capital and surplus of at least $2 million and again become
eligible for listing on Nasdaq in the event that the Offer is not consummated.
 
     If the Offer is consummated, the Shares may not become eligible for listing
on Nasdaq, depending upon the aggregate market value and the per share price of
any Shares not purchased pursuant to the Offer, the number of publicly held
Shares, the number of stockholders and other applicable standards for initial
inclusion
 
                                        9
<PAGE>   21
 
on Nasdaq. In such event, quotations might still continue to be available from
the OTC Bulletin Board. The extent of the public market for the Shares and
availability of such quotations would, however, depend upon the number of
holders of Shares remaining at such time, the interest in maintaining a market
in the Shares on the part of securities firms, the possible termination of
registration under the Exchange Act, as described below, and other factors.
 
     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 not listed on a national securities
exchange or Nasdaq and there are fewer than 300 holders of record of the Shares.
According to the Company, as of January 28, 1997, there were approximately 620
holders of record of Shares. Termination of registration of the Shares under the
Exchange Act would reduce substantially 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. Furthermore,
if the registration of the Shares under the Exchange Act were to be terminated,
the ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
under the Securities Act of 1933, as amended, may be impaired or eliminated. It
is the present intention of the Purchaser to seek to cause the Company to make
an application for termination of registration of the Shares as soon as possible
following the consummation of the Offer if the requirements for termination of
registration are met.
 
8. CERTAIN INFORMATION CONCERNING THE COMPANY.
 
     The Company is a Delaware corporation with its principal executive offices
at 2283 Cosmos Court, Carlsbad, California 92009. As reported by the Company,
the Company's principal line of business is designing, developing, manufacturing
and distributing intraoral cameras and computer imaging systems and related
software exclusively to the dental marketplace.
 
     The Company has informed Parent that it has experienced severe financial
difficulties which raised substantial doubts about its ability to continue as a
going concern. In each of its last three fiscal years, the Company had net
losses, totalling approximately $11.2 million, $11.9 million and $2.2 million in
fiscal 1996, 1995 and 1994, respectively. For the fiscal quarter ended September
30, 1996, the Company reported a net loss of approximately $1.3 million. The
Company has also informed Parent that it has experienced severe constraints on
its liquidity, has been unable to obtain sufficient infusions of equity or debt
capital either in a timely manner or on acceptable terms and has been delinquent
on certain payments to its vendors under the terms of applicable vendor invoices
and has suffered delays or interruptions in the receipt of needed components.
 
     Set forth below is certain selected consolidated financial information with
respect to the Company and its subsidiaries excerpted or derived from the
information contained in the Company's Form 10-K for the fiscal year ended June
30, 1996 and its Form 10-Q for the quarterly period ended September 30, 1996.
More comprehensive financial information is included in such reports and other
documents filed by the Company with the Commission, and the following summary is
qualified in its entirety by reference to such reports and such other documents
and all the financial information (including any related notes) contained
therein. Such reports and other documents should be available for inspection and

Parent to the Purchaser. Parent plans to obtain funds for such capital
contribution or intercompany loan from its available sources of cash, including
its cash on hand, its revolving loan facility or short-term bank borrowings.
However, the Purchaser has not conditioned the Offer on obtaining financing.
 
11. CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER.
 
     Parent designs, develops, manufactures and markets a broad range of
products for the dental market, and distributes its dental products worldwide.
As part of its business, Parent continually seeks to develop, either internally
or through acquisitions, new products for the dental market.
 
     Executives of the Company approached Parent in September 1996 to inquire as
to Parent's interest in a possible acquisition of the Company. Parent decided to
pursue discussions with the Company in order to determine whether the Company's
intraoral cameras and computer imaging systems and related software for the
dental market would be a strategic fit for Parent's business.
 
                                       13
<PAGE>   25
 
     Parent had previously considered an acquisition of the Company in July
1994, at which time discussions had led to the execution of a letter of intent.
Under that letter of intent, subject to certain conditions, including Parent's
completion of a satisfactory due diligence investigation of the Company and the
negotiation and execution of definitive agreements, Parent agreed to acquire the
Company for a price of $16 3/8 per share in a cash transaction (the "Previous
Proposal"). No definitive agreements were executed in connection with the
Previous Proposal. In September 1994, Parent terminated the letter of intent
relating to the Previous Proposal because issues identified in its due diligence
investigation of the Company could not be resolved to Parent's satisfaction.
Although Parent discussed with the Company the possibility of negotiating a
transaction at a significantly lower price, the parties could not reach
agreement, and all discussions with respect to the Previous Proposal terminated
in September 1994.
 
     In a meeting held on September 30, 1996, executives of the Company informed
Parent of the Company's operating losses since the end of the Company's fiscal
1994 and of the Company's financial difficulties and severe liquidity
constraints. The parties also discussed the Company's business and explored
whether Parent was willing to consider an acquisition of the Company. The
parties met again in October 1996 and signed a Mutual Confidential
Non-Disclosure Agreement dated October 8, 1996 (the "Mutual Confidential Non-
Disclosure Agreement") preceding Parent's review of certain confidential
information concerning the Company.
 
     Executives of Parent and the Company met again in November 1996 and
discussed the deteriorating financial condition of the Company. Among other
matters, the parties discussed the fact that the Company was in default under
certain covenants in its senior credit agreement with Coast Business Credit, a
division of Southern Pacific Thrift & Loan Association ("Coast"), and its
subordinated credit agreement with Mercury Partners, LLC ("Mercury"), and did
not have sufficient cash to meet its current obligations. At that time, Parent
informed the Company that it would be prepared to consider acquiring the
Company, subject to certain conditions, at a purchase price of $2.00 per share
in cash, and, subject to reaching agreement with Coast and Mercury, to make
funds available to the Company to enable the Company to continue operations. In
December 1996, Mr. Edmunds, Chief Executive Officer and President of the
Company, informed Parent that the Company's Board of Directors had authorized
him to negotiate a letter of intent with Parent at the price Parent had
proposed, and that the Company would require up to $3 million to continue
operations in the period prior to consummation of a transaction.
 
     Representatives of Parent and the Company had a series of meetings and
telephone conferences in December 1996 to negotiate a letter of intent and a
credit arrangement. Representatives of Parent also met with representatives of
Coast and Mercury to discuss the circumstances under which Coast and Mercury
would be willing to forbear from exercising default remedies against the Company
during the time period while Parent was completing a due diligence investigation
of the Company and pending the consummation of an acquisition transaction. Such
discussions included Parent's willingness to loan up to $3 million to the
Company because the Company could not continue operations for any significant
period of time without such funding.
 
     Following these meetings, on December 11, 1996, the Board of Directors of
Parent approved in principle an acquisition transaction at $2.00 per share,
subject to final approval by the Executive Committee of such Board, and also
approved the Credit Agreement (as defined below). On December 24, 1996, Parent
and the Company signed a letter of intent (the "Letter of Intent") pursuant to
which Parent, subject to certain conditions, agreed to acquire the Company for
$2.00 per share in a cash transaction. On the same date, Parent, the Company and
Insight Imaging Systems, Inc., a wholly owned subsidiary of the Company
("Insight"), entered into a Credit Agreement (the "Credit Agreement"), and
certain security agreements ancillary to the Credit Agreement, which provided
for Parent to make available a line of credit of up to an aggregate principal
amount of $3 million to the Company. Parent loaned the Company $2.5 million
under the Credit Agreement on December 24, 1996; no further advances have been
made since such date. Also on the same date, Coast purchased from Mercury the
indebtedness owed to Mercury by the Company, and Coast agreed (as more fully
described below) to forbear from exercising its default rights and remedies
through the earlier of March 25, 1997 or the date on which the Letter of Intent
terminates other than by execution of a definitive merger agreement.

<PAGE>   26
 
     Representatives of Parent and the Company held meetings and telephone
conferences in January 1997 to discuss the business and operations of the
Company and to negotiate the terms of the Merger Agreement and the transactions
contemplated thereby. During this time the Company's Board of Directors retained
the investment banking firm of Cleary Gull to consider the fairness from a
financial point of view of the Offer and the Merger. Cleary Gull has in the past
provided financial and/or investment banking services to Parent and was Parent's
financial advisor in connection with the Previous Proposal discussed above.
Except for certain trading activities relating to Parent's securities, Cleary
Gull has not rendered any financial advisory or investment banking services to
Parent since the termination of discussions relating to the Previous Proposal in
September 1994. In the ordinary course of its business, Cleary Gull may trade
securities of Parent and the Company for its own account and for the account of
its customers.
 
     A meeting of the Company's Board of Directors was held on January 20, 1997
at which Cleary Gull delivered its oral opinion (which it subsequently confirmed
in writing) that as of the date thereof the consideration to be received by
holders of Shares in each of the Offer and the Merger is fair to such holders
from a financial point of view. The Board of Directors of the Company, by
unanimous written consent dated January 27, 1997, determined that the Offer and
the Merger are fair to, and in the best interests of, the Company and its
stockholders, and unanimously approved the Merger Agreement and the transactions
contemplated thereby and unanimously recommended that all holders of Shares
tender their Shares pursuant to the Offer and determined to recommend that
stockholders of the Company vote in favor of the approval and adoption of the
Merger Agreement if such approval is required by applicable law. On January 21,
1997, the Executive Committee of the Board of Directors of Parent and the Board
of Directors of the Purchaser approved the Merger Agreement, the Offer and the
transactions contemplated thereby.
 
     Following such approvals, the parties executed the Merger Agreement on
January 27, 1997, and issued a press release announcing such execution on
January 28, 1997.
 
     CREDIT AGREEMENT; SUBORDINATION AND INTERCREDITOR AGREEMENT; FORBEARANCE
LETTER.
 
     The following summaries of the Credit Agreement, the Subordination and
Intercreditor Agreement (as defined below) and the Forbearance Letter (as
defined below) are qualified in their entirety by reference to the Credit
Agreement, the Subordination and Intercreditor Agreement and Forbearance Letter,
copies of which are filed as Exhibits (b)(1), (b)(2) and (b)(3), respectively,
to the Schedule 14D-1. The Credit Agreement, the Subordination and Intercreditor
Agreement and the Forbearance Letter should be read in their entirety for a more
complete description of the matters summarized below.
 
     On December 24, 1996, the Company, Insight (together with the Company,
"Borrower"), and Parent entered into the Credit Agreement pursuant to which,
among other things, Parent agreed to make available to Borrower a line of credit
(the "Line") of up to an aggregate principal amount of $3 million (the "Maximum
Available Credit").
 
     Upon execution and delivery of the Credit Agreement, Parent made an advance
to Borrower under the Line of $2.5 million to pay necessary and reasonable
operating expenses required to keep Borrower operating as a going concern
through the Termination Date (as defined below). Pursuant to the Credit
Agreement, at any time and from time to time during the term of the Credit
Agreement and until the Termination Date, Borrower may request an Advance (as
defined in the Credit Agreement), and Parent will make such Advance upon the
terms and subject to the conditions of the Credit Agreement if such Advance is
to be used as set forth in the preceding sentence. Parent may also in its sole
and absolute discretion make Advances to be used by Borrower for any other
purpose related to the operation of Borrower's business. Since December 24,
1996, Parent has made no additional Advances, so that the aggregate amount
loaned to the Company under the Credit Agreement is $2.5 million, and thus there
is, as of the date of this Offer to Purchase, $0.5 million additional borrowing
capacity available to Borrower under the Credit Agreement. Each outstanding
Advance is, and each future Advance will be, evidenced by a note (the "Note").
All of Borrower's indebtedness under the Credit Agreement is subordinated to the
extent provided in the Subordination and Intercreditor Agreement.
 
                                       15
<PAGE>   27
 
     Advances bear interest on the unpaid principal balance outstanding at any
time at the floating interest rate of 4% per annum in excess of the prime rate
of interest set forth in the Money Rates Section of The Wall Street Journal
rounded up to the nearest one-eighth (the "Line Interest Rate") or such lesser
rate permitted by applicable law if the Line Interest Rate would violate
applicable law. Except as otherwise provided in the Credit Agreement, Borrower
is obligated to pay in full all unpaid principal on the Line and all interest
accrued but unpaid thereon on March 25, 1997.
 
     Pursuant to the Credit Agreement, Borrower granted to Parent a security
interest and lien on the Collateral (as defined in the Credit Agreement), which
includes, without limitation, all of Borrower's rights, title and interest in
and to all of its personal property, rights, interests and privileges. In
connection therewith, Borrower and Parent entered into certain security
agreements.
 
     The Credit Agreement will terminate on the date (the "Termination Date") on
which (a) there is an Event of Default (as defined below) with respect to which
Parent has declared all principal and interest on the Note to be immediately due
and payable or with respect to which all principal and interest is immediately
due and payable without any declaration by Parent, or (b) the date of the
earliest to occur of (i) the termination of the Letter of Intent other than by
means of the execution and delivery of a definitive merger agreement as
contemplated therein, (ii) the termination of the Merger Agreement other than by
means of the consummation of the transactions contemplated therein or (iii)
March 25, 1997.
 
     The Credit Agreement provides that the occurrence of any one or more of the
following events will constitute an Event of Default under the Credit Agreement
and the Note: (a) Borrower fails to pay as and when due any principal or
interest under the Credit Agreement or under the Note, or uses the proceeds of
Advances in violation of the terms thereof; (b) Borrower fails to observe or
perform any obligation or any covenant to be observed or performed by it under
the Credit Agreement or under the Note or in any other agreement between Parent
and Borrower; (c) Borrower defaults after December 24, 1996 in the payment or
performance of any material obligation or material indebtedness to another
person whether then existing or thereafter incurred including, without
limitation, any event of default as defined in the Coast Agreement (as defined
below) that is not then subject to Coast's forbearance under the terms of the
Forbearance Letter; (d) any material statement, certificate, report,
representation or warranty made or furnished by Borrower in the Credit Agreement
or in compliance with the provisions thereof proves to have been false or
misleading in any material respect at the time when made, deemed made or
furnished; (e) (i) any money judgment, writ or warrant of attachment or similar
process involving an amount in excess of $50,000 is entered or filed against
Borrower or any of its assets or properties and remains undischarged for a
period of 30 days, or (ii) any judgment or order of any court or administrative
agency awarding damages under the federal securities laws or in any action
seeking reimbursement, indemnification or contribution with respect to payment
of any such claim is filed against Borrower; (f) Borrower (i) applies for or
consents to the appointment of a receiver, trustee or liquidator of itself or of
its property, (ii) is unable, or admits in writing inability, to pay its debts
as they mature, (iii) makes a general assignment for the benefit of creditors,
(iv) is adjudicated a bankrupt or insolvent, (v) files a voluntary petition in
bankruptcy, or a petition or answer seeking reorganization or an arrangement

by execution of a definitive merger agreement as contemplated therein.
 
12. PURPOSE OF THE OFFER; SHORT FORM MERGER; PLANS FOR THE COMPANY; DISSENTERS'
    RIGHTS; GOING PRIVATE TRANSACTIONS.
 
     Purpose.  The purpose of the Offer is to acquire control of, and the entire
equity interest in, the Company. Following the Offer, the Purchaser and Parent
intend to acquire any remaining equity interest in the Company not acquired in
the Offer by consummating the Merger.
 
     Vote Required to Approve Merger.  The DGCL requires, among other things,
that the adoption of any plan of merger or consolidation of the Company must be
approved by the Board of Directors and generally by the holders of the Company's
outstanding voting securities. The Board of Directors of the Company has
approved the Offer and the Merger; consequently, the only additional action of
the Company that may be necessary to effect the Merger is approval by such
stockholders if the short-form merger procedure described below is not
available. Under the DGCL and pursuant to the Company's Bylaws, the affirmative
vote of holders of a majority of the outstanding Shares (including any Shares
owned by the Purchaser) is required to approve the Merger. If the Purchaser
acquires, through the Offer or otherwise, voting power with respect to at least
a majority of the outstanding Shares (which would be the case if the Minimum
Tender Condition were satisfied and the Purchaser were to accept for payment
Shares tendered pursuant to the Offer), it would have sufficient voting power to
effect the Merger without the vote of any other stockholder of the Company. The
Company would, however, be required to provide certain notice of the Merger to
stockholders, as required by law. However, the DGCL also provides 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 intends to,
effect the Merger without prior notice to, or any action by, any other
stockholder of the Company.
 
                                       17
<PAGE>   29
 
     Plans for the Company.  Except as set forth in this Offer to Purchase, it
is expected that, initially following the Merger, the business and operations of
the Company will be continued by the Company as the corporation surviving the
Merger substantially as they are currently being conducted. The directors of the
Purchaser will be the initial directors of the Surviving Corporation, and the
officers of Purchaser and such other persons as are designated by Parent will be
the initial officers of the Surviving Corporation. Upon completion of the Offer
and the Merger, Parent intends to conduct a detailed review of the Company and
its assets, corporate structure, dividend policy, capitalization, operations,
properties, policies, management and personnel and to consider, subject to the
terms of the Merger Agreement, what, if any, changes would be desirable in light
of the circumstances then existing, and will take such actions or effect such
changes as it deems desirable.
 
     Except as otherwise described in this Offer to Purchase, the Purchaser and
Parent have no current plans or proposals that would relate to, or result in,
any extraordinary corporate transaction involving the Company, such as a
reorganization or liquidation involving the Company or any of its subsidiaries,
a sale or transfer of a material amount of assets of the Company or any of its
subsidiaries, any change in the Company's capitalization or dividend policy or
any other material change in the Company's business, corporate structure or
personnel.
 
     Dissenters' Rights.  Holders of Shares do not have dissenters' rights as a
result of the Offer. However, if the Merger is consummated, holders of Shares
will have certain rights pursuant to the provisions of Section 262 of the DGCL
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. 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 asset values and the investment value of the Shares. The value
so determined could be more or less than the Offer Price or the Merger
Consideration (as defined below).
 
     If any holder of Shares who demands appraisal under Section 262 of the DGCL
fails to perfect, or effectively withdraws or loses his right to appraisal, as
provided in the DGCL, the Shares of such stockholder will be converted into the
right to receive the Merger Consideration in accordance with the Merger
Agreement. A stockholder may withdraw his demand for appraisal by delivery to
Parent of a written withdrawal of his demand for appraisal and acceptance of the
terms of the Merger.
 
     A stockholder seeking to exercise dissenters' rights under Section 262 of
the DGCL may not tender Shares in the Offer and will be further advised by the
Company as to the steps necessary to exercise such rights. FAILURE TO FOLLOW THE
STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR PERFECTING APPRAISAL RIGHTS MAY
RESULT IN THE LOSS OF SUCH RIGHTS.
 
     Going Private Transactions.  The Merger would have to comply with any
applicable federal law operative at the time of its consummation. Rule 13e-3
under the Exchange Act is applicable to certain "going private" transactions.
The Purchaser does not believe that Rule 13e-3 will be applicable to the Merger
unless the Merger is consummated more than one year after the termination of the
Offer. If applicable, Rule 13e-3 would require, among other things, that certain
financial information concerning the Company and certain information relating to
the fairness of the Merger and the consideration offered to minority
shareholders be filed with the Commission and disclosed to minority shareholders
prior to consummation of the Merger.
 
13. THE MERGER AGREEMENT; THE STOCKHOLDER AGREEMENTS; THE EMPLOYMENT AGREEMENT.
 
     MERGER AGREEMENT.
 
     The following 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 Schedule 14D-1. The Merger Agreement should be read in its entirety for a
more complete description of the matters summarized below.
 
     The Offer.  Pursuant to the Merger Agreement, the Purchaser has made the
Offer to purchase all the outstanding Shares at $2.00 per Share in cash, without
interest, upon the terms and subject to the conditions
 
                                       18
<PAGE>   30
 
set forth in this Offer to Purchase. The Merger Agreement provides that the
obligation of Purchaser to consummate the Offer is subject to the satisfaction
of the Minimum Tender Condition and certain other conditions that are described
in Section 15 hereof. The Merger Agreement provides that Parent and Purchaser
will not, without the written consent of the Company, decrease the Offer Price,
change the form of consideration payable in the Offer, decrease the number of
Shares sought in the Offer, change the conditions of the Offer from those
contained in the Appendix thereto, impose additional conditions to the Offer, or
amend any material term of the Offer in a manner adverse to the holders of
Shares.
 
     The Merger.  Upon the terms and subject to the conditions of the Merger
Agreement, and in accordance with the DGCL, at the Effective Time the Purchaser
will be merged with and into the Company, the separate corporate existence of
the Purchaser will cease and the Company will continue as the Surviving
Corporation. Parent may elect at any time prior to the Merger to merge the
Company with and into the Purchaser, in which event the parties agree to execute
an appropriate amendment to the Merger Agreement to reflect the foregoing. The
Certificate of Incorporation and Bylaws of the Purchaser will be the Certificate
of Incorporation and Bylaws of the Surviving Corporation until amended as
provided therein or in the DGCL.
 
     Conversion of Shares; Stock Options and Warrants.  At the Effective Time,
each then outstanding Share (other than Shares owned by the Company, Parent, the
Purchaser, any other Subsidiary of Parent or by stockholders who are entitled to
and who properly exercise dissenters' rights under the DGCL) will be converted
into the right to receive $2.00 in cash, without interest (the "Merger
Consideration"). At the Effective Time, each option and each warrant, whether or
not then exercisable in accordance with its terms, will be converted into the
right to receive, upon the surrender of the agreement evidencing such stock
option or warrant and upon the delivery of a stock option acknowledgment or
warrant acknowledgment, in accordance with the terms of the Merger Agreement, an
amount in cash (net of applicable withholding) equal to the excess, if any, of
the Merger Consideration over the exercise price per share of the common stock
of the Company subject to such stock option or warrant, as the case may be,
multiplied by the number of shares previously subject to such stock option or
warrant.
 
     Board Representation.  The Merger Agreement provides that, upon the
acceptance for payment of, and payment for, any Shares by Purchaser pursuant to
the Offer which, when taken together with any Shares which Parent beneficially
owns (as such term is defined under the Exchange Act), represent at least a
majority of the then outstanding Shares, Purchaser will be entitled at such time
to designate the directors on the Board of Directors of the Company, and the
Company will, at such time, obtain resignations of all then-serving Directors
and, prior to such resignations, cause Purchaser's designees to be elected to,
and to constitute all of, the Board of Directors of the Company. The Merger
Agreement provides that the Company agrees to cooperate in permitting the
exercise by Purchaser of its rights set forth in this paragraph including,
without limitation, (x) cooperating in satisfying the requirements of Section
14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and (y)
amending, prior to the Expiration Date of the Offer, any provisions of the
Bylaws or any agreement by which the Company is bound that could delay or hinder
the ability of Purchaser or Parent to elect its designees to a majority of the
directorships constituting the Board of Directors of the Company. The Merger
Agreement provides that the Company will not take any action to delay or hinder
such election.
 
     Directors' and Officers' Insurance Coverage.  The Merger Agreement provides
that, for six years after the earlier of (i) the date on which the designees of
the Purchaser have been elected to the Board of Directors of the Company
pursuant to the provisions set forth in the preceding paragraph and constitute
all of the members thereof and (ii) the Effective Time, Parent and the Surviving
Corporation will indemnify, defend and hold harmless the present officers,
directors, employees and agents of the Company and its Subsidiaries (each an
"Indemnified Party") against all losses, claims, damages, liabilities, fees and
expenses (including reasonable fees and disbursements of counsel) and judgments,
fines, losses, claims, liabilities and amounts paid in settlement (provided that
any such settlement is effected with the prior written consent of Parent or the
Surviving Corporation (which consent shall not be unreasonably withheld))
arising out of actions or omissions occurring at or prior to the Effective Time
(including without limitation matters arising out of or pertaining to the
transactions contemplated by the Merger Agreement) to the full extent permitted
by the DGCL or the Company's Certificate of Incorporation or Bylaws as in effect
on the date of the Merger Agreement, including
 
                                       19
<PAGE>   31
 
provisions therein relating to the advancement of expenses incurred in the
defense of any action or suit; provided, however, that in the event any claim or
claims are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until
disposition of the claim to which such rights are applicable.
 
     The Merger Agreement provides that, for two years after the Effective Time,
Parent and the Surviving Corporation will (i) maintain the current policies of
officers' and directors' liability insurance in respect of acts or omissions
(including without limitation matters arising out of or pertaining to the
transactions contemplated by the Merger Agreement) occurring at or prior to the
Effective Time covering each person who is an officer or director of the Company
on the date of the Merger Agreement and who is currently covered by the
Company's officers' and directors' liability insurance policy, or (ii)
substitute policies providing substantially similar coverage containing terms
and conditions that, taken together, are not materially less advantageous, and
provided that such substitution does not result in gaps or lapses in coverage.
 
     The Merger Agreement provides that Parent and the Surviving Corporation
will pay all expenses (including attorneys' fees) that may be incurred by any
Indemnified Party or person having rights to coverage pursuant to the provisions
set forth under this caption "Directors' and Officers' Insurance Coverage"
(collectively, "Covered Persons") in enforcing the obligations of Parent and the
Surviving Corporation provided for therein, provided that no such expenses will
be payable if such Indemnified Party or person is found, in or as a result of
such enforcement action, not to have the rights to coverage claimed by such
Indemnified Party or person. The Merger Agreement provides for equitable
remedies including without limitation the right to specific performance for any
breach of the obligations under the indemnification provisions.
 
     The Merger Agreement provides that the rights set forth under this caption
"Directors' and Officers' Insurance Coverage" are contingent upon the occurrence
of, and shall survive the consummation of, the Offer, are intended to benefit
the Company, the Surviving Corporation and each Covered Person, shall be binding
on all successors and assigns of Parent and the Surviving Corporation and shall
be enforceable by each Covered Person, each of whom shall be a third party
beneficiary of these provisions.
 
     Benefit Plans and Certain Contracts.  Pursuant to the Merger Agreement,
Parent agreed to cause the Surviving Corporation to pay, in accordance with
their terms as in effect on the date of the Merger Agreement, all amounts due
and payable under the terms of all written employment contracts, agreements,
plans, policies and written commitments of the Company and its subsidiaries (the
"Subsidiaries") with or with respect to its current employees, officers and
directors as such contracts, agreements, plans, policies and written commitments
are described in the disclosure schedule to the Merger Agreement. For at least
two years following the Effective Time, each employee of the Company and its
Subsidiaries (while such person remains an employee of the Company and its
Subsidiaries) shall be entitled to participate in all benefit plans maintained
or sponsored by the Company or in benefit plans providing substantially similar
benefits. Upon or prior to the consummation of the Offer, Parent and the Company
will enter into the Employment Agreement with Mr. Edmunds.
 
     Stockholders' Meeting.  The Merger Agreement provides that if the approval
of the Merger by the Company's stockholders (the "Company Stockholder Approval")
is required by law, the Company will, at Parent's request, as soon as
practicable following acceptance for payment of and payment for Shares, duly
call, give notice of, convene and hold a meeting of its stockholders (the
"Stockholders' Meeting") for the purpose of obtaining such Company Stockholder
Approval. The Merger Agreement provides that the Company will, through its Board
of Directors, recommend to its stockholders that such Company Stockholder
Approval be given. Notwithstanding the foregoing, the Merger Agreement provides
that if Parent, Purchaser or any other subsidiary of Parent shall acquire at
least 90% of the outstanding Shares, the parties will, at the request of Parent,
take all necessary and appropriate action to cause the Merger to become
effective as soon as practicable after the expiration of the Offer without a
Stockholders' Meeting in accordance with Section 253 of the DGCL. The Merger
Agreement provides that, without limiting the generality of the foregoing, the
Company agrees that its obligations pursuant to the first sentence of this
paragraph shall not be affected by (i) the commencement, public proposal, public
disclosure or communication to the Company of any
 
                                       20
<PAGE>   32
 
"Acquisition Proposal" (as defined below) that is not a "Superior Acquisition
Proposal" (as defined below) or (ii) the withdrawal or modification by the Board
of Directors of the Company of its approval or recommendation of the Offer, the
Merger Agreement or the Merger. The Merger Agreement provides that Parent agrees
to cause all Shares purchased pursuant to the Offer and all other Shares owned
by Purchaser or any other subsidiary of Parent to be voted in favor of the
Merger.
 
     Conditions to the Merger.  The Merger Agreement provides that the
respective obligations of each party to effect the Merger is subject to the
fulfillment or waiver at or prior to the Effective Time of the following
conditions: (a) if required by the DGCL, the Merger Agreement has been approved
and adopted by the requisite vote of the stockholders of the Company; (b) no
statute, rule, regulation, executive order, decree, temporary restraining order,
preliminary injunction or other order or legal restraint or prohibition
preventing the consummation of the Merger has been issued by any federal, state

orders or approvals of, or declarations or filings with, or expiration of
waiting periods imposed by, any Governmental Entity necessary for the
consummation of the Merger and the transactions contemplated by the Merger
Agreement have been filed, occurred or been obtained and shall be in effect at
the Effective Time. The obligation of the Company to effect the Merger is also
subject to the condition that each of Parent and the Purchaser have made the
Offer and have consummated the Offer in accordance with its terms.
 
     Representations and Warranties.  Pursuant to the Merger Agreement, the
Company has made customary representations and warranties to Parent and the
Purchaser relating to the Company and its Subsidiaries, including, among other
things, with respect to: organization and qualification, capitalization,

will maintain in full force and effect its current policies of directors' and

     Actions by Parent and the Purchaser Pending the Merger.  The Merger
Agreement provides that none of the provisions contained in the preceding
paragraph will prohibit Parent or the Purchaser (or any of their respective
subsidiaries), during the period between the payment for Shares pursuant to the
Offer and the
 
                                       22
<PAGE>   34
 
Effective Time, from taking or causing to be taken any action with respect to
the business of the Company and its Subsidiaries that Parent or the Purchaser
(or any of their respective subsidiaries) would legally be permitted to take or
cause to be taken with respect to a majority owned subsidiary of Parent or the
Purchaser (or any of their respective subsidiaries), provided that Parent will
not take any action in violation of the terms of the Merger Agreement that would
cause Parent's obligations to effect the Merger hereunder to not be satisfied
and provided further that any such action taken by or at the direction of Parent
or the Purchaser (or any of their respective subsidiaries) will not cause a
breach by the Company of any of the provisions of the preceding paragraph.
 
     Exclusive Dealing.  The Merger Agreement provides that neither the Company
nor any of its Subsidiaries, officers, directors, or the directors and officers
of its Subsidiaries, nor any of its other affiliates (each, an "Affiliate")
will, and the Company will cause its and its respective Affiliates' employees,
agents and representatives (including, without limitation, any investment
banking, legal or accounting firm retained by the Company or any of its
Affiliates and any individual member or employee of the foregoing) (each, an
"Agent") not to: (i) initiate, solicit or seek, directly or indirectly, any
inquiries or the making or implementation of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders or any of them)
with respect to a merger, acquisition, consolidation, recapitalization,
liquidation, dissolution or similar transaction involving, or any purchase of
all or a substantial portion of the assets or any equity securities of, the
Company or any of its Subsidiaries, except for the transactions contemplated by
the Merger Agreement (any such proposal or offer being hereinafter referred to
as an "Acquisition Proposal"); or (ii) engage in any negotiations concerning, or
provide any confidential information or data to, or have any discussions with,
any person relating to an Acquisition Proposal; or (iii) otherwise cooperate in
any effort or attempt to make, implement or accept an Acquisition Proposal;
provided, however, that the Company may, if it receives an Acquisition Proposal
which was not directly or indirectly initiated, solicited or otherwise sought by
the Company or by any of its Affiliates or its or their respective Agents, and
which is a Superior Acquisition Proposal, respond to such Superior Acquisition
Proposal by engaging in negotiations with respect thereto and providing
nonpublic information concerning the Company to the person making such Superior
Acquisition Proposal, provided that such person has entered into a written
confidentiality agreement on terms no more favorable to such person than the
Mutual Confidential Non-Disclosure Agreement is to Parent, and provided further
that the Company has received a written opinion of its outside counsel that such
response is required in order to satisfy the fiduciary duties imposed under
applicable law on its Board of Directors. The Company will take the necessary
steps to inform the individuals and entities referred to in the first sentence
hereof of the obligations undertaken in this paragraph.
 
     The Merger Agreement provides that, unless it has theretofore been
terminated pursuant to clause (f) under the caption "Termination," neither the
Board of Directors of the Company nor any committee thereof will (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent or
Purchaser, the approval or recommendation by such Board of Directors or any such
committee of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend, or propose to approve or recommend, any Acquisition Proposal or (iii)
enter into any agreement with respect to any Acquisition Proposal. The Merger
Agreement provides that, notwithstanding the foregoing, in the event the Board
of Directors of the Company receives an Acquisition Proposal that constitutes a
Superior Acquisition Proposal, the Board of Directors may (subject to the
limitations contained in this paragraph) withdraw or modify its approval or
recommendation of the Offer, the Merger Agreement or the Merger, approve or
recommend any such Superior Acquisition Proposal, enter into an agreement with
respect to any such Superior Acquisition Proposal or terminate this Agreement in
each case at any time after 48 hours following Parent's receipt of written
notice (a "Notice of Superior Acquisition Proposal") advising Parent that the
Board of Directors has received a Superior Acquisition Proposal, specifying the
material terms and conditions of such Superior Acquisition Proposal and
identifying the person making such Superior Acquisition Proposal. For purposes
of the Merger Agreement, a "Superior Acquisition Proposal" means an Acquisition
Proposal received by the Company without violation of the provisions contained
in the preceding paragraph, having terms which the Board of Directors of the
Company determines, in the exercise of its fiduciary duties, after consultation
with outside counsel, and upon the written opinion of its outside financial
advisor, to be more favorable to the Company's stockholders from a financial
point of view than the Offer and the Merger.
 
                                       23
<PAGE>   35
 
     The Merger Agreement provides that, in addition to the obligations of the
Company set forth in the preceding paragraph, the Company will promptly advise
Parent orally and in writing of any request for nonpublic information relating
to the Company or by any person that, to the Company's knowledge, may be
considering making, or has made, an Acquisition Proposal or the receipt of any
Acquisition Proposal, or any inquiry with respect to any Acquisition Proposal,
the material terms and conditions of such request, Acquisition Proposal or
inquiry, and the identity of the person making any such Acquisition Proposal or
inquiry. The Company will keep Parent fully informed of the status and details
of any such request, Acquisition Proposal or inquiry.
 
     Fees and Expenses.  Except as provided below, the Merger Agreement provides
that, whether or not the Offer and/or the Merger are consummated, each of the
Company and Parent will separately bear its own expenses, including the fees and
disbursements of counsel, investment bankers and accountants, incurred in
connection with the Offer, the Merger, the Merger Agreement and the transactions
contemplated thereby.
 
     The Merger Agreement also provides that if the Company or any affiliate or
agent of the Company fails to fulfill its obligations described above under the
caption "Exclusive Dealing," or enters into an agreement which contemplates the
sale of all or any material portion of the assets of, or any equity interest in,
the Company to a third party, or the parties to the Stockholder Agreements or
any of them enters into an agreement which contemplates such a transaction,
then, in any such case, the Company will promptly reimburse Parent for all its
out-of-pocket expenses incurred in connection with the Offer, the Merger, the
Merger Agreement, the Stockholder Agreements or any transactions contemplated by
the Merger Agreement or the Stockholder Agreements.
 
     Termination.  The Merger Agreement may be terminated at any time prior to
the Effective Time, whether prior to or after any approval by the stockholders
of the Company:
 
     (a) by mutual written consent of the Boards of Directors of Parent and the
Company;
 
     (b) by Parent, if (i) neither Parent nor any subsidiary of Parent has
accepted for payment any Shares pursuant to the Offer by the sixtieth day
following commencement of the Offer and such failure is not in breach of the
Offer or the Merger Agreement, or (ii) Parent has properly terminated the Offer
in accordance with its terms; provided that Parent may not terminate the Merger
Agreement pursuant to this provision if (A) the failure of Parent or the
Purchaser to fulfill any obligation under the Merger Agreement has been the
cause of, or resulted in, the circumstances described in clause (i), or (B) in
the case of clause (ii), Parent or the Purchaser has not exercised such right by
the close of business on or before the fifth business day following the
termination of the Offer in accordance with its terms;
 
     (c) by Parent and the Purchaser prior to the purchase of Shares pursuant to
the Offer, if there has been any material breach of a material obligation of the
Company hereunder and such breach has not been remedied within five days after
receipt by the Company of notice in writing from Parent or the Purchaser
specifying such breach and requesting that it be remedied;
 
     (d) by the Company prior to the purchase of Shares pursuant to the Offer,
if there has been any material breach of a material obligation of Parent or the
Purchaser hereunder and such breach has not been remedied within five days after
receipt by Parent or the Purchaser, as the case may be, of notice in writing
from the Company specifying such breach and requesting that it be remedied;
 
     (e) by the Company, if (i) the Offer has not been commenced on or before
the fifth business day after the announcement to the public of the execution of
the Merger Agreement, (ii) the Offer is terminated without the purchase of any
Shares and such termination is in breach of the Offer or the Merger Agreement,
or (iii) Parent or the Purchaser has failed to pay or to cause another entity to
pay for Shares duly and properly tendered in the Offer within 10 business days
following expiration of the Offer, provided that the Company may not terminate
the Merger Agreement pursuant to this provision if the failure of the Company to
fulfill any obligation under the Merger Agreement has been the cause of, or
resulted in, the circumstances described in clauses (i), (ii) or (iii) above;
 
                                       24
<PAGE>   36
 
     (f) by the Company or by Parent and the Purchaser prior to the purchase of
Shares pursuant to the Offer, if a Superior Acquisition Proposal is received and
the Board of Directors of the Company withdraws or modifies its recommendation
of the Offer or recommends to the stockholders of the Company that such
stockholders tender their Shares into, or vote in favor of, such Superior
Acquisition Proposal, provided that such termination shall not affect the
Company's obligations to pay the expenses of Parent and the Purchaser set forth
above in the second paragraph under the caption "Fees and Expenses;" or
 
     (g) by the Company or by Parent and the Purchaser if there is any law or
regulation that makes consummation of the Merger illegal or otherwise prohibited
or if any judgment, injunction, order or decree enjoining Parent, the Purchaser
or the Company from consummating the Merger is entered and such judgment,
injunction, order or decree becomes final and nonappealable.
 
     The Merger Agreement provides that in the event of termination of the
Merger Agreement prior to the Purchase of Shares, the Merger Agreement will
forthwith become void and of no effect, and there will be no liability on the
part of Parent, the Purchaser or the Company, except as set forth in the second
paragraph under "Fees and Expenses" or as otherwise expressly provided in the
Merger Agreement, and (b) nothing in the Merger Agreement will relieve any party
from liability for any willful or grossly negligent breach of any representation
or warranty or any breach prior to such termination of any covenant or agreement
contained herein.
 
     Entire Agreement.  The Merger Agreement provides that the Merger Agreement
(including the Appendix thereto and the documents and instruments referred to
therein) constitutes the entire agreement and supersedes all other prior
agreements and undertakings, both written and oral, among the parties, or any of
them, with respect to the subject matter thereof, provided, however, that (i)
Paragraph 5 of the Letter of Intent, (ii) the Credit Agreement, (iii) the
Subordination and Intercreditor Agreement, and (iv) the Mutual Confidential
Non-Disclosure Agreement will remain in effect in accordance with their terms.
 
     Amendment.  The Merger Agreement provides that it may not be amended except
by an instrument in writing signed on behalf of each of the parties, and
provided that any amendment effected after obtaining the Company Stockholder
Approval may be subject to further approval of the Company's stockholders if
required by the DGCL.
 
     STOCKHOLDER AGREEMENTS.
 
     The following summary of the Stockholder Agreements is qualified in its
entirety by reference to the Stockholder Agreements, copies of which are filed
as Exhibits (c)(2) through (c)(14) to the Schedule 14D-1. The Stockholder
Agreements should be read in their entirety for a more complete description of
the matters summarized below.
 
     Tender of Shares.  In connection with the execution of the Merger
Agreement, Parent and the Purchaser entered into Stockholder Agreements with the
Stockholder Parties. Upon the terms and subject to the conditions of such
agreements, each Stockholder Party agreed to validly tender (or cause the record
holder of such Shares to validly tender) and not withdraw, pursuant to and in
accordance with the terms of the Offer, the number of Shares owned beneficially
by such Stockholder Party and any Shares acquired by such Stockholder Party in
any capacity after the date of the respective Stockholder Agreement. The
Stockholder Parties currently own a total of 537,795 Shares, representing
approximately 9.8% of the outstanding Shares as of January 27, 1997. Each
Stockholder Party also consented to the treatment of the stock options and the
warrants held by such party as described under "The Merger Agreement--Conversion
of Shares; Stock Options and Warrants" above.
 
     Provisions Concerning Shares.  Each Stockholder Party has agreed that
during the period commencing on the date of such party's Stockholder Agreement
and continuing until the termination of the Merger Agreement in accordance with
its terms, at any meeting of the Company's stockholders or in connection with
any written consent of the Company's stockholders, such Stockholder Party will
vote (or cause to be voted) the Shares held of record or beneficially owned by
such party: (i) in favor of the Merger, the execution and delivery by the
Company of the Merger Agreement and the approval of the terms thereof and each
of the
 
                                       25
<PAGE>   37
 
other actions contemplated by the Merger Agreement and such Stockholder
Agreement and any actions required in furtherance thereof; and (ii) against any
Acquisition Proposal and against any action or agreement that would impede,
frustrate, prevent or nullify such Stockholder Agreement or result in a breach
in any respect of any covenant, representation or warranty or any other
obligation or agreement of the Company under the Merger Agreement or which would
result in any of the conditions of the Offer or of the Merger not being
fulfilled. The Stockholder Agreements also provide that, notwithstanding
anything therein to the contrary, each Stockholder Party, in his or her capacity
as a director and/or officer of the Company, as the case may be, and in
accordance with the Merger Agreement, may exercise his or her fiduciary duties
with respect to the Company. Each Stockholder Party also agreed, among other
things, not to transfer such party's Shares and, in such party's capacity as a
stockholder of the Company, not to, directly or indirectly, encourage, solicit,
participate in or initiate discussions or negotiations with, or provide any
information to, any corporation, partnership, person or other entity or group
(other than Parent, any of its affiliates or representatives) concerning any
Acquisition Proposal.
 
     EMPLOYMENT AGREEMENT.
 
     The following summary of the Employment Agreement is qualified in its
entirety by reference to the form of Employment Agreement, a copy of which is
filed as Exhibit (c)(15) to the Schedule 14D-1. The Employment Agreement should
be read in its entirety for a more complete description of the matters
summarized below.
 
     Upon or prior to consummation of the Offer, Parent, the Company and Mr.
Edmunds will enter into the Employment Agreement, pursuant to which Mr. Edmunds
will be employed as Vice President and General Manager of the Company or any
entity (including a division of Parent) that succeeds to all or any substantial
part of the business and operations of the Company for a term commencing on the
effective date of the Employment Agreement and expiring on February 28, 1999
(the "Term"), unless sooner terminated as described below. Thereafter Mr.
Edmunds will become an at-will employee of the Company.
 
     Pursuant to the Employment Agreement, Mr. Edmunds will (i) receive an
initial base salary of not less than $180,000, or such larger amount as may from
time to time be fixed by Parent, (ii) be entitled to bonus compensation that is
comparable (in the manner in which it is determined and with respect to the
timing of payment) to that of Parent's domestic executive employees who perform
duties and have responsibilities comparable to those of Mr. Edmunds, (iii) be
entitled to participate in all plans and other benefits made available by Parent
generally to its domestic executive employees who perform duties and have
responsibilities comparable to those of Mr. Edmunds and (iv) be eligible to
participate in Parent's 1993 Stock Option Plan. Parent's management will
recommend to the Compensation Committee of Parent's Board of Directors that Mr.
Edmunds be granted options under such plan in an amount that is determined in a
manner comparable to the manner in which option grants are determined for
Parent's domestic executive employees who perform duties and have
responsibilities comparable to those of Mr. Edmunds.
 
     The Employment Agreement provides that, upon termination of Mr. Edmunds'
employment for any reason, he will be entitled to receive the compensation
accrued and unpaid as of the date of his termination, including his pro rata
share of any bonus or other incentive payment to which he is otherwise entitled
that becomes payable with respect to the year in which termination of employment
occurred.
 
     The Employment Agreement provides that Mr. Edmunds may terminate the
Employment Agreement at any time after the occurrence of certain events
specified therein (any such event, "Good Reason"). If the Employment Agreement
is terminated by Mr. Edmunds for "Good Reason" or by the Company for certain
reasons specified in the Employment Agreement, the Company will continue to pay
compensation and provide benefits for a period beginning on the date of the
termination notice and ending on the later of the second anniversary of such
date or February 28, 1999. Neither the Company nor Parent will be obligated to
continue to pay such compensation or provide benefits if Mr. Edmunds' employment
is terminated because of gross negligence or significant willful misconduct.
 
                                       26
<PAGE>   38
 
     If at any time during the Term after a Change of Control (as defined in the
Employment Agreement) Mr. Edmunds terminates his employment for Good Reason, or
Parent or the Company terminates or gives written notice of termination, then in
lieu of any periodic payments to which he is otherwise entitled, Mr. Edmunds
will receive, at his election, within five business days of such termination,
the present value of such periodic payments.
 
14. DIVIDENDS AND DISTRIBUTIONS.
 
     Pursuant to the Merger Agreement, the Company has agreed that, from the
date of the Merger Agreement until the Effective Time, it will not, and will not
permit any of its Subsidiaries to, split, combine or reclassify any shares of
its outstanding capital stock or declare, set aside or pay any dividend or other
distribution payable in cash, stock or property or redeem or otherwise acquire
any shares of its capital stock. In addition, the Company has agreed that, for
such period, it will not, and will cause its Subsidiaries not to, authorize for
issuance, issue or sell any additional shares of, or rights of any kind to
acquire any shares of, its capital stock, of any class, except for unissued
Shares reserved for issuance upon the exercise of stock options or warrants
outstanding on the date of the Merger Agreement in accordance with their
existing terms.
 
15. CERTAIN CONDITIONS OF THE OFFER.
 
     The Merger Agreement provides that, notwithstanding any other term of the
Offer or the Merger Agreement, Parent or the Purchaser shall not be required to
accept for payment or to pay for any Shares tendered pursuant to the Offer, and
may terminate or, subject to the provisions of the Merger Agreement, amend the
Offer and may postpone the acceptance for payment of Shares pursuant thereto,
unless (a) the Minimum Tender Condition has been met and, (b) any waiting period
under the HSR Act applicable to the purchase of Shares pursuant to the Offer
shall have expired or been terminated (the "HSR Condition"), provided, however,
that prior to March 25, 1997, Parent will not terminate the Offer by reason of
the nonsatisfaction of the HSR Condition and, if the HSR Condition is the only
condition that is not satisfied upon the expiration of the Offer, Parent shall
cause the Offer to be extended to March 24, 1997.
 
     The Merger Agreement also provides that, notwithstanding any other term of
the Offer or the Merger Agreement, Parent or the Purchaser will not be required
to accept for payment or to pay for any Shares tendered pursuant to the Offer,
and may terminate or, subject to the provisions of the Merger Agreement, amend
the Offer and may postpone the acceptance for payment of Shares pursuant thereto
if, at any time on or after the date of the Merger Agreement and before the
acceptance of such Shares for payment or the payment therefor, any of the
following conditions exists:
 
     (a) any statute, rule, regulation or order has been proposed, enacted,
entered or deemed applicable to the Offer or the Merger (i) making the purchase
of, or payment for, some or all of the Shares pursuant to the Offer or the
Merger Agreement illegal, or resulting in a material delay in the ability of
Parent to accept for payment or pay for some or all of the Shares, or to
consummate the Offer or Merger or seeking to obtain from the Company, Parent or
the Purchaser any damages that would have a Material Adverse Effect on the
Company or Parent, (ii) imposing material limitations on the ability of Parent
or the Purchaser effectively to acquire or hold or to exercise full rights of
ownership of the Shares acquired by it, including the right to vote the Shares
purchased by it on all matters properly presented to the stockholders of the
Company, (iii) which would require Parent or any direct or indirect subsidiary
of Parent to dispose of or hold separate any of the Shares or all or any
material portion of the assets or business of the Company and its Subsidiaries,
or (iv) prohibit or limit the ability of Parent or any direct or indirect
subsidiary of Parent to own, control or operate the Company or any of its
Subsidiaries or all or any material portion of the businesses, operations or
assets of the Company and its Subsidiaries, where such prohibition or limitation
would have a Material Adverse Effect on the Company; or
 
     (b) any governmental or regulatory action or proceeding by or before any
Governmental Entity is instituted or pending, which would reasonably be expected
to result in any of the consequences referred to in clauses (i) through (iv) of
paragraph (a) above; or
 
                                       27
<PAGE>   39
 
     (c) the Company has not complied with its agreements and covenants in the
Merger Agreement, or any of its representations and warranties in the Merger
Agreement, when made or at and as of any time thereafter, are inaccurate or
incomplete, except (i) where such failure so to comply or such inaccuracy or
incompleteness would not reasonably be expected to have a Material Adverse
Effect on the Company, (ii) for changes specifically permitted by the Merger
Agreement or (iii) those representations and warranties that address matters
only as of a particular day must be accurate and complete as of such date; or
 
     (d) there has occurred an event of default set forth in the Coast
Agreement, as to which event of default Coast has not given a written waiver or
is not required to forbear under the terms of the Forbearance Letter; or
 
     (e) the Company commences a case under any chapter of Title XI of the
United States Code or any similar law or regulation; or a petition under any
chapter of Title XI of the United States Code or any similar law or regulation
is filed against the Company which is not dismissed within five business days;
or the Company applies for or consents to the appointment of a receiver, trustee
or liquidator of itself or of its property; or the Company makes a general
assignment for the benefit of creditors; or an order, judgment or decree is
entered, without the application, approval or consent of the Company by any
court of competent jurisdiction, approving a petition seeking a reorganization
of the Company or appointing a receiver, trustee or liquidator of the Company or
of all or a substantial part of its assets, and such order, judgment or decree
continues unstayed for a period of five business days; or the Company takes
corporate action for the purpose of effecting any of the foregoing; or
 
     (f) there has occurred (i) the declaration of a banking moratorium or any
suspension of payments in respect of banks in the United States, (ii) the
commencement of a war, armed hostilities or other international or national
calamity directly or indirectly involving the United States, (iii) any
limitation by any governmental authority on the extension of credit by banks or
other financial institutions, or (iv) in the case of any of the foregoing
existing at the time of the commencement of the Offer, a material acceleration
or worsening thereof; or
 
     (g) the Merger Agreement has been terminated in accordance with its terms;
 
which, in Parent's sole discretion, in any such case regardless of the
circumstances giving rise to any such conditions, makes it inadvisable to
proceed with such acceptance for payment or payment or makes it advisable to
terminate or amend the Offer.
 
     The Merger Agreement provides that the foregoing conditions are for the
sole benefit of Parent and the Purchaser and may be asserted by Parent or the
Purchaser regardless of the circumstances giving rise to any such conditions or
may be waived by Parent or 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 shall not be
deemed a waiver of any such right and each right shall be deemed an ongoing
right which may be asserted at any time and from time to time. Any determination
by Parent or the Purchaser concerning any events described in the above
conditions shall be final and binding on all parties.
 
16. CERTAIN LEGAL MATTERS.
 
     Except as described in this Section 16, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning 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 approval or other action by any Governmental Entity that would
be required for the acquisition or ownership of Shares by the Purchaser as
contemplated herein other than pursuant to the HSR Act. 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 described below under
"State Takeover Laws." While, except as otherwise expressly described in this
Section 16, the Purchaser does not currently 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
 
                                       28
<PAGE>   40
 
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 15 "Certain Conditions
of the Offer."
 
     State Takeover Laws.  A number of states have enacted takeover statutes
that purport, in varying degrees, to be applicable to attempts to acquire
securities of corporations that are incorporated or have assets, stockholders,
executive offices or places of business in such states. In CTS Corp. v. Dynamics
Corp. of America, the Supreme Court of the United States held that a state may
constitutionally disqualify a potential acquiror from voting on the affairs of a
target corporation without prior approval of the remaining stockholders,
provided that such laws were applicable only under certain conditions.
 
     Section 203 of the DGCL limits the ability of certain Delaware corporations
to engage in business combinations with "interested stockholders" (defined as
any beneficial owner of 15% or more of the outstanding voting stock of the
corporation) unless, among other things, the corporation's board of directors
has given its prior approval to either the business combination or the
transaction which resulted in the stockholder becoming an "interested
stockholder." The Company does not have a class of voting stock that is (i)
listed on a national securities exchange, (ii) authorized for quotation on The
Nasdaq Stock Market or (iii) held of record by more than 2,000 stockholders. In
addition, the Company's Board of Directors has approved the Merger Agreement,
the Stockholder Agreements and the Purchaser's acquisition of Shares pursuant to
the Offer. Therefore, Section 203 of the DGCL is inapplicable to the Merger.
 
     Based on representations and warranties of the Company, the Purchaser does
not believe that any state takeover statutes purport to apply to the Offer or
the Merger. Neither the Purchaser nor Parent has currently complied with any
state takeover statute or regulation. The Purchaser reserves the right to
challenge the applicability or validity of any state law purportedly applicable
to the Offer or the Merger and nothing in this Offer to Purchase or any action
taken in connection with the Offer or the Merger is intended as a waiver of such
right. If it is asserted that any state takeover statute is applicable to the
Offer or the Merger and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer or the Merger, the Purchaser
might be required to file certain information with, or to receive approvals
from, the relevant state authorities, and the Purchaser might be unable to
accept for payment or pay for Shares tendered pursuant to the Offer, or be
delayed in consummating the Offer or the Merger. In such case, the Purchaser may
not be obliged to accept for payment or pay for any Shares tendered pursuant to
the Offer.
 
     Antitrust.  Under the provisions of the HSR Act applicable to the Offer,
the purchase of Shares pursuant to the Offer may be consummated following the
expiration of a 15-calendar day waiting period following the filing by Parent of
a Notification and Report Form with respect to the Offer, unless Parent receives
a request for additional information or documentary material from the Antitrust
Division or the FTC or unless early termination of the waiting period is
granted. Parent made such filing on January 29, 1997. If, within the initial
15-day waiting period, either the Antitrust Division or the FTC requests
additional information or material from Parent concerning the Offer, the waiting
period will be extended and will expire at 11:59 p.m., New York City time, on
the tenth calendar day following the date of substantial compliance with such
request. Only one extension of the waiting period pursuant to a request for
additional information is authorized by the HSR Act. Thereafter, such waiting
period may be extended only by court order or with the consent of Parent.
Complying with a request for additional information or material can take a
significant amount of time. In addition, if the Antitrust Division or the FTC
raises substantive issues in connection with a proposed transaction, the parties
frequently engage in negotiations with the relevant governmental agency
concerning possible means of addressing those issues and may agree to delay
consummation of the transaction while such negotiations continue.
 
     The Merger would not require an additional filing under the HSR Act if the
Purchaser owns 50% or more of the outstanding Shares at the time of the Merger
or if the Merger occurs within one year after the HSR Act waiting period
applicable to the Offer expires or is terminated.
 
                                       29
<PAGE>   41
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed acquisition
of the Company. At any time before or after the Purchaser's 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 result thereof.
 
17. FEES AND EXPENSES.
 
     Robert W. Baird & Co. Incorporated ("Baird") is acting as Dealer Manager in
connection with the Offer. Parent has agreed to pay Baird as compensation for
all such services a total of $90,000. In addition, Parent has agreed (i) to
reimburse Baird for its out-of-pocket expenses, including the reasonable fees
and expenses of its counsel, in connection with the Offer, and (ii) to indemnify
Baird and certain related persons against certain liabilities and expenses,
including certain liabilities under the federal securities laws.
 
     The Purchaser has retained D.F. King & Co., Inc. to act as the Information
Agent and Harris Trust and Savings Bank to serve as the Depositary in connection
with the Offer. The Information Agent and the Depositary each will receive
reasonable and customary compensation for their services, be reimbursed for
certain reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection therewith, including certain liabilities
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 Dealer Manager and the
Information Agent) in connection with the solicitation of tenders of Shares
pursuant to the Offer. Brokers, dealers, banks and trust companies will be
reimbursed by the Purchaser upon request for customary mailing and handling
expenses incurred by them in forwarding material to their customers.
 
18. 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

                       TERMS AND CONDITIONS OF THE OFFER
 
    1. SIGNATURE GUARANTEES.  No signature guarantee is required on this Letter
of Transmittal (a) if this Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this document, shall include any
participant in a Book-Entry Transfer Facility whose name appears on a security
position listing as the owner of Shares) of Shares tendered herewith, unless
such holder(s) has completed either the box entitled "Special Delivery
Instructions" or the box entitled "Special Payment Instructions" on the reverse
hereof, or (b) if such Shares are tendered for the account of a firm that is a
member of a registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
having an office or correspondent in the United States or by any other "eligible
guarantor institution," as such term is defined in Rule 17Ad-15 under the
Securities Exchange Act of 1934, as amended (each, an "Eligible Institution").
In all other cases, all signatures on this Letter of Transmittal must be
guaranteed by an Eligible Institution. See Instruction 5.
 
    2. REQUIREMENTS OF TENDER.  This Letter of Transmittal is to be completed by
stockholders either if certificates are to be forwarded herewith or 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 validly to tender
Shares pursuant to the Offer, either (a) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), together with any required
signature guarantees and any other required documents, must be received by the
Depositary at one of its addresses set forth herein prior to the Expiration Date
and either (i) certificates for tendered Shares must be received by the
Depositary at one of such addresses prior to the Expiration Date or (ii) Shares
must be delivered pursuant to the procedures for book-entry transfer set forth
herein and a Book-Entry Confirmation must be received by the Depositary prior to
the Expiration Date or (b) the tendering stockholder must comply with the
guaranteed delivery procedures set forth below and in Section 2 of the Offer to
Purchase.
 
    Stockholders whose certificates for Shares are not immediately available or
who cannot deliver their certificates and all other required documents to the
Depositary or complete the procedures for book-entry transfer prior to the
Expiration Date may tender their Shares by properly completing and duly
executing the Notice of Guaranteed Delivery pursuant to the guaranteed delivery
procedures set forth in Section 2 of the Offer to Purchase.
 
    Pursuant to such procedures, (a) such tender must be made by or through an
Eligible Institution, (b) a properly completed and duly executed Notice of
Guaranteed Delivery substantially in the form provided by the Purchaser must be
received by the Depositary prior to the Expiration Date and (c) the certificates
for all physically delivered Shares or a Book-Entry Confirmation with respect to
all tendered Shares, as well as a properly completed and duly executed Letter of
Transmittal (or facsimile thereof) with any required signature guarantees and
any other documents required by this Letter of Transmittal, must be received by
the Depositary within three New York Stock Exchange, Inc. trading days after the
date of execution of the Notice of Guaranteed Delivery.
 
    THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. 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.
 
    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 certificates (for the remainder of
the Shares that were evidenced by the old certificates) 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 expiration of the Offer.
All Shares represented by certificates delivered to the Depositary will be
deemed to have been tendered unless otherwise indicated.
 
    5. SIGNATURES ON LETTERS 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 to so act must be submitted.
<PAGE>   55
 
    When this Letter of Transmittal is signed by the registered holder(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 holder(s). Signatures on such certificates or
stock powers must be guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of certificates listed, the certificates must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered owner or owners appear on the certificates.
Signatures on such certificates or stock powers must be guaranteed by an
Eligible Institution.
 
    6. STOCK TRANSFER TAXES.  The Purchaser will pay any stock transfer taxes
with respect to the transfer and sale of Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares not tendered or accepted for payment are to be
registered in the name of, any persons other than the registered holder(s) or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder(s) or such person) payable on
account of the transfer to such person 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 tendered or not accepted for
payment are to be issued 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.  Subject to the terms of the Offer, the Purchaser
reserves the absolute right in its sole discretion to waive any of the specified
conditions of the Offer, in whole or in part, in the case of any Shares
tendered.
 
    9. BACKUP WITHHOLDING.  Under U.S. federal income tax law, a stockholder
whose tendered Shares are accepted for payment is required to provide the
Depositary with such stockholder's correct Taxpayer Identification Number
("TIN") on Substitute Form W-9 below and to certify whether the stockholder is
subject to backup withholding of federal income tax. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31% federal income tax withholding on the payment of the purchase price.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the stockholder or other payee. Backup withholding is
not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld, provided that the
required information is given to the Internal Revenue Service. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN is
provided to the Depositary. However, such amounts will be refunded to such
stockholder if a TIN is provided to the Depositary within 60 days.
 
    The stockholder is required to give the Depositary the TIN (e.g., Social
Security Number or Employer Identification Number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which TIN to report.
 
    10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for additional
copies of the Offer to Purchase, this Letter of Transmittal, the Notice of
Guaranteed Delivery and the Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 should be directed to the
Information Agent at its address set forth below. Questions or requests for
assistance may be directed to the Information Agent or the Dealer Manager.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE COPY
THEREOF (TOGETHER WITH CERTIFICATES FOR, OR A BOOK-ENTRY CONFIRMATION WITH
RESPECT TO, TENDERED SHARES WITH ANY REQUIRED SIGNATURE GUARANTEES AND ALL OTHER
REQUIRED DOCUMENTS) MUST BE RECEIVED BY THE DEPOSITARY, OR THE NOTICE OF
GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, PRIOR TO THE EXPIRATION
DATE.

              THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00

     The Offer is conditioned upon, among other things, there being validly

Shares which would represent at least 55% of all outstanding Shares as of the
date of commencement of the Offer.

and the Company pursuant to which, following the consummation of the Offer, the

effective date of the Merger, each outstanding Share (other than Shares held in
the treasury of the Company or owned by Parent or any direct or indirect
subsidiary of Parent (including the Purchaser)) will be converted into the
right to receive $2.00 in cash, without interest. The Purchaser and Parent have
also entered into stockholder agreements with each executive officer and
director of the Company who, in each case, beneficially owns Shares, and the
William W. Stevens and Virda J. Stevens Trust, a stockholder of the Company,
under which such stockholders have agreed to tender their Shares into the
Offer. As of the date of this notice, such stockholders own approximately 9.8%
of the outstanding Shares.


<PAGE>   65

     THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT THE OFFER AND
THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS
STOCKHOLDERS, HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY AND UNANIMOUSLY RECOMMENDS THAT ALL HOLDERS
OF SHARES TENDER THEIR SHARES PURSUANT TO THE OFFER.

     For purposes of the Offer, the Purchaser shall be deemed to have accepted
for payment, and thereby purchased, Shares validly tendered and not properly
withdrawn as, if and when the Purchaser gives oral or written notice to the
Depositary (as defined in the Offer to Purchase) of the Purchaser's acceptance
for payment of such Shares. Upon the terms and subject to the conditions of the
Offer, payment for Shares 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 stockholders whose Shares have been
accepted for payment. A stockholder desiring to tender such stockholder's
Shares must comply with the terms and conditions set forth in Section 2 of the
Offer to Purchase.

     The term "Expiration Date" means 12:00 Midnight, New York City time, on
March 3, 1997, 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. Any extension of the Offer 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
12:00 Midnight, New York City time, on March 3, 1997 (or, if the Purchaser
shall have extended the period of time during which the Offer is open, the
latest time and date at which the Offer, as so extended by the Purchaser, shall
expire), and, unless theretofore accepted for payment, may also be withdrawn at
any time after April 1, 1997. For a withdrawal to be effective, a written,
telegraphic or facsimile transmission notice of withdrawal must be timely
received by the Depositary at one of its addresses set forth in the Offer to
Purchase and must specify the name of the person having tendered the Shares to
be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder of the Shares to be withdrawn, if different from the name of
the person who tendered the Shares. If certificates for Shares have been
delivered or otherwise identified to the Depositary, then, prior to the
physical release of such certificates, the serial numbers shown on such
certificates must be submitted to the Depositary and, unless such Shares have
been tendered by any Eligible Institution (as defined in the Offer to
Purchase), the signature on the notice of withdrawal must be guaranteed by an
Eligible Institution. If Shares have been delivered pursuant to the procedures
for book-entry transfer as set forth in the Offer to Purchase, any notice of
withdrawal must also specify the name and number of the account at the
appropriate book-entry transfer facility to be credited with the withdrawn
Shares and otherwise comply with such book-entry transfer facility's
procedures. Withdrawals of tenders of Shares may not be rescinded, and any
Shares properly withdrawn will thereafter be deemed not validly tendered for
purposes of the Offer. However, withdrawn Shares may be retendered by again
following the applicable procedures described in Section 2 of the Offer to
Purchase at any time prior to the Expiration Date.

     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,

                                      -2-

              DENTSPLY INTERNATIONAL INC. AND NEW IMAGE INDUSTRIES
                             SIGN MERGER AGREEMENT

York, Pa, -- (Business Wire) -- January 28, 1997. DENTSPLY International Inc.
(Nasdaq- XRAY) and New Image Industries, Inc. today announced that they have
entered into a definitive merger agreement under which DENTSPLY will commence a
cash tender offer for all of the outstanding shares of New Image at a price of
$2.00 per share. New Image, based in Carlsbad, California, designs, develops,
manufactures and distributes intra-oral cameras and computer imaging systems
and related software exclusively to the dental market. New Image's products
include the AcuCam, MultiCam, AcuCam Concept III, Plug N' Play, and Multilink
Video Operatory Network intra-oral camera systems as well as the dental
operatory software programs, Capture-It and Chart-It.

The terms and conditions of DENTSPLY's cash tender offer will be set forth in
the offering documents expected to be filed by February 3, 1997 with the
Securities and Exchange Commission. Conditions to DENTSPLY's purchase of shares
in the offer include the tender of at least 55% of all shares of New Image that
are outstanding as of the commencement of the offer, and expiration of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act.

Under the merger agreement, which has been approved by the boards of directors
of each company, a newly created subsidiary of DENTSPLY will be merged into New
Image following completion of the tender offer and New Image will become a
wholly owned subsidiary of DENTSPLY. DENTSPLY has also entered into agreements
with certain stockholders of New Image, including its directors and senior
executive officers, and the William W. Stevens and Virda J. Stevens Trust, who
own in the aggregate 10% of New Image's shares outstanding, whereby each has
agreed to tender his or her shares in the offer. The net cash cost to DENTSPLY
of purchasing the outstanding equity of New Image (excluding transaction costs)
is expected to be approximately $11.4 million.

Request, Lender shall make the Advance requested on the proposed Funding Date
in accordance with Borrower's Funding Requests.

         (c) Lender agrees that it shall approve the Advance set forth in a
Funding Request if the Advance requested thereby is to be used to pay necessary
and reasonable operating expenses of the Business required to keep it operating
as a going concern through the Termination Date including, without limitation,
accounts payable which are due as of the date of such request. Lender shall not
be required to, but in its sole and absolute discretion may, advance funds to
be used by Borrower for any other purpose related to the operation of the
Business.  The Initial Advance and each subsequent Advance shall be evidenced
by the Note in the form attached hereto as Schedule 2.3(c). No third party is
intended to be a beneficiary of this provision (or of any other provision of
this Agreement).

     2.4 Maximum Available Credit. The aggregate amount of principal which
Borrower may have outstanding under the Line at any time shall not exceed the
Maximum Available Credit. Borrower agrees, without notice or demand,
immediately to repay, any principal balance of the Line in excess of the
Maximum Available Credit.

     2.5 Principal and Interest Payments.

         (a) Interest shall accrue on the principal balance outstanding under
the Line at the Line Interest Rate. All unpaid principal on the Line and all
interest accrued but unpaid thereon shall be paid in full by Borrower on March
25, 1997 (or as otherwise provided herein or in the Note). Prior to the
Termination Date, accrued interest shall be calculated monthly and capitalized,
and constitute outstanding principal but such capitalized interest shall not be
considered principal for purposes of determining the Maximum Available Credit.

         (b) Without in any way limiting Lender's rights and remedies hereunder
and under the Note in the case of Events of Default, any principal payments on
the Line not paid when due and, to the extent permitted by applicable law, any
interest payment on the Line not paid when due, and any other amount due to
Lender under this Agreement not paid when due, shall thereafter bear interest
payable upon demand at a rate which is three percent (3%) per annum in excess
of the applicable Line Interest Rate.

         (c) Borrower may prepay the Advances, in whole or in part from time to
time, without penalty.

                              ARTICLE 3 - SECURITY

     3.1 Grant of Security Interests. To secure the prompt and complete payment
when due of all of its Obligations and the performance by Borrower of all of
the covenants and obligations to be performed by it pursuant to this Agreement,
Borrower hereby assigns and pledges to Lender

                                       6

and grants to Lender a security interest in and lien on all of Borrower's
right, title and interest in and to all of the Collateral, wherever located,
whether now owned or existing or hereafter arising or acquired.

     3.2 Continuing Liability of Borrower. The security interests described
above are granted as security only and shall not subject Lender, or transfer or
in way affect or modify, any obligation or liability of Borrower with respect
to, any of the Collateral or any transaction in connection therewith. Lender
shall not be required or obligated in any manner to make any inquiry as to the
nature or sufficiency of any payment received by it or the sufficiency of any
performance by any party under any such obligation, or to make any payment or
present or file any claim, or to take any action to collect or enforce any
performance or the payment of any amount thereunder to which any such Person
may be entitled at any time.

     3.3 Filings; Further Assurances. Borrower will, from time to time, at its
expense and in such manner and form as Lender may reasonably require, execute,
deliver, file and record Financing Statements and any other statements,
continuation statement, specific assignment or other instrument or document and
take any other action that may be necessary or desirable, to create, preserve,
perfect or validate the security interests created hereunder or to enable
Lender to exercise and enforce its rights hereunder with respect to any of the
Collateral.

     3.4 Power of Attorney. Borrower hereby authorizes Lender, and gives Lender
its irrevocable power of attorney (which authorization is coupled with an
interest), in the name of Borrower or otherwise, to execute, deliver, file and
record any financing statement, continuation statement, specific assignment or
other paper and to take any other action that Lender in its sole discretion may
deem necessary or appropriate to further perfect the security interests created
hereby. Borrower agrees that a carbon, photographic, photostatic, or other
reproduction of this Agreement or of a financing statement is sufficient as a
financing statement where permitted by applicable law.

     3.5 Place of Business; Change of Name. As of the Effective Date, the chief
executive office of the Borrower and its chief place of business, the locations
of the Collateral and the location where it maintains all records relating to
the Collateral are listed on Schedule 3.5 hereto. Borrower will not (x) change
its principal place of business or chief executive office from the location
listed on such Schedule, (y) change its name, identity or corporate structure
or (z) change the location of the Collateral or its records relating to the
Collateral from those specified on Schedule 3.5 hereto, unless in any such
event Borrower shall have given Lender at least sixty (60) days' (or such
shorter period to which Lender may consent in writing) prior written notice
thereof and shall have taken all action necessary or reasonably requested
(including without limitation appropriate opinions of counsel) by Lender to
amend its existing financing statements and continuation statements so that
they are not misleading and to file additional financing statements in all
applicable jurisdictions to perfect the security interests of Lender in all of
the Collateral.

     3.6 Maintenance of Collateral. If Borrower fails to do so, Lender may, at
its option,

                                       7


<PAGE>   77



pay and discharge taxes, liens, security interests and other encumbrances
pertaining to the Collateral (except Permitted Liens), and may pay for the
maintenance and preservation of the Collateral to prevent a material
deterioration from its present condition and for insurance thereon in order to
keep the Collateral in salable condition. Borrower agrees to reimburse Lender
promptly after notice thereof for any payment so made.

operations or properties of Borrower.

its important activities, in the business of extending credit for the purpose
of "purchasing" or "carrying" any "margin stock" (as each of the quoted terms
is defined or used in Regulation G, T, U or X). No part of the proceeds of any

leased properties, no Hazardous Material was generated, treated, stored,
disposed of, used, handled or manufactured at, or transported, shipped or
disposed of from, such current or previously owned properties, and there were
no Releases of Hazardous Material in, on, under or affecting any such property
or any surrounding site. The term "Release" has the meaning set forth in 42

violated or, by conducting its business as now conducted or currently proposed
to be conducted by Borrower, would violate any patent, trade secret, trademark,
service mark, trade name, copyright, license, information, proprietary right or

knowledge, there is no basis for any such allegation. Borrower has taken
reasonable steps to protect its trade secrets and confidential information.

infringement or adverse use of Borrower's rights to or in any material
know-how, processes, trade secrets, trademarks, service marks, trade names,
copyrights, licenses, information, proprietary rights or other material rights
of Borrower.  To the best of Borrower's knowledge, neither the execution nor
delivery of this Agreement, nor the carrying on of Borrower's business as now
conducted or under development by Borrower, will conflict with or result in a
material breach of the terms, conditions or provisions of, or constitute a
material default under or a material violation of, any fiduciary duty or any
contract, covenant or instrument under which any of Borrower's employees is now
obligated.

continue unstayed and in effect for any period of 30 consecutive days;

         (h) If (i) any person or group within the meaning of Section 13(d)(3)
of the Securities Exchange Act of 1934, as amended (the "1934 Act") and the
rules and regulations promulgated thereunder other than Lender shall have
acquired beneficial ownership (within the meaning of Rule 13d-3 of the 1934

<PAGE>   89



Board of Directors of the Company. For purposes of clause (i) above, a person

or otherwise) of Borrower; or

         (l) Borrower shall cease to conduct its Business substantially as it
is conducted as of the Effective Date, or Borrower shall change the nature of
its Business.

     7.2 Remedies on Default. Upon the occurrence of an Event of Default:

         (a) In addition to the rights specifically granted hereunder or now or
hereafter existing in equity, at law, by virtue of statute or otherwise (each
of which rights may be exercised at any time and from time to time), Lender may
at its election forthwith declare all principal and interest to be immediately
due and payable, without protest, demand or other notice (which are hereby
expressly waived by Borrower). Upon the occurrence of an Event of Default
specified in Article 7.1(f) or (g) above, all obligations, including all
principal and interest, shall be immediately due and payable without any
declaration by Lender.

         (b) Lender shall have all the rights of a secured creditor under the
Uniform Commercial Code.

         (c) Borrower will pay, as part of the Obligations secured hereunder,
Lender's administrative fees and all other amounts (including but not limited

taxes, levies and insurance on, or maintenance of, the Collateral; and (ii) in
taking possession of, disposing of, or preserving such Collateral.

or agents as attorneys-in-fact of Borrower upon the occurrence and continuation
of an Event of Default, irrevocably and with power of substitution, with
authority to sign Borrower's name on any

                                       20


<PAGE>   90



Financing Statements relating to the Collateral; to endorse the name of
Borrower on any notes, acceptances, checks, drafts, money orders or other
evidence of payment or proceeds of the Collateral that come into Lender's
possession; to sign the name of Borrower on any invoices, documents, drafts
against and notices to account debtors of Borrower, assignments and request for
verification of accounts; to execute proofs of claim and loss; to execute any
endorsements, assignments or other instruments of conveyance or transfer; and
to do any and all acts and things necessary or advisable in the sole discretion
of Lender to carry out and enforce this Agreement. All acts of said attorney or
designee are hereby ratified and approved and said attorney or designee shall
not be liable for any acts of commission or omission, nor for any error of
judgment or mistake of fact or law. This power of attorney being coupled with
an interest is irrevocable while any of the Obligations shall remain unpaid or
Lender has any obligation or ability to make Advances hereunder.

         (e) Any cash proceeds of sale, lease or other disposition of
Collateral upon an Event of Default shall be applied in the following order:
(i) to Lender's costs; (ii) to the payment of interest due pursuant to this
Agreement or the Note; (iii) to the payment of principal due pursuant to this
Agreement or the Note; and (iv) any surplus then remaining to Borrower or
whomever may be lawfully entitled thereto.

         (f) The remedies provided herein or in the Note or otherwise available
to Lender at law or in equity shall be cumulative and concurrent, and may be
pursued singly, successively or together at the sole discretion of Lender, and
may be exercised as often as occasion therefor shall occur; and the failure to
exercise any such right or remedy shall in no event be construed as a waiver or
release of the same.

                           ARTICLE 8 - MISCELLANEOUS

     8.1 Amendments, Etc. No amendment to or waiver of any provision of this
Agreement nor consent to any departure by Borrower, shall in any event be
effective unless (a) the same shall be in writing and signed by Lender and
Borrower (with respect to an amendment) or Lender (with respect to a waiver or
consent by it) or Borrower (with respect to a waiver or consent by it), as the
case may be, and such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given. This Agreement contains
a final and complete integration of all prior expressions by the parties hereto
with respect to the subject matter hereof and shall constitute the entire
agreement (together with the Schedules hereto) among the parties hereto with
respect to the subject matter hereof, superseding all prior oral or written
understandings.

     8.2 Notices, Etc. All notices and other communications provided for
hereunder shall, unless otherwise stated herein, be in writing (including
communication by facsimile copy) and mailed, return receipt requested,
transmitted or delivered, as to each party hereto, at its address or facsimile

address

<PAGE>   91



as shall be designated by such party in a written notice to the other parties.
All such notices and communications shall be effective, upon receipt, or in the
case of delivery by mail, five days after being deposited in the mails, or, in
the case of notice by facsimile copy, when verbal communication of receipt is
obtained.

     8.3 Binding Effect; Assignability. This Agreement shall be binding upon
and inure to the benefit of Borrower and Lender and their respective successors
and permitted assigns (which successors of Borrower shall include a trustee in
bankruptcy). Borrower may not assign any of its rights and obligations
hereunder or any interest herein without the prior written consent of Lender.
Lender may assign at any time its rights and obligations hereunder and
interests herein to any other Person without the consent of Borrower. Borrower
hereby consents to the foregoing and agrees to cooperate with any such Person
electing to exercise Lender's rights under this Agreement. This Agreement shall
create and constitute the continuing obligations of the parties hereto in
accordance with its terms, and shall remain in full force and effect until such
time as the Collection Date shall occur; provided, however, that the rights and
remedies with respect to any breach of any representation and warranty or
covenant made by the Borrower pursuant to Article 5 and Article 6 shall be
continuing and shall survive until all Obligations are satisfied in full.

     8.4 GOVERNING LAW; WAIVER OF JURY TRIAL. THIS AGREEMENT AND THE NOTE SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH
OF PENNSYLVANIA WITHOUT REGARD TO CONFLICT OF LAWS. BORROWER HEREBY AGREES TO
THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE COMMONWEALTH OF PENNSYLVANIA
FOR THE COUNTY OF YORK AND THE UNITED STATES DISTRICT COURT OF THE MIDDLE
DISTRICT OF PENNSYLVANIA AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS
UPON IT AND CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY REGISTERED
MAIL DIRECTED TO BORROWER AT THE ADDRESS SET FORTH ON THE SIGNATURE PAGE HEREOF
AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED FIVE (5) DAYS AFTER THE
SAME SHALL HAVE BEEN DEPOSITED IN THE U.S. MAILS, POSTAGE PREPAID. BORROWER
HEREBY WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE,
WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE BETWEEN BORROWER AND LENDER
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT. INSTEAD, ANY DISPUTE RESOLVED
IN COURT WILL BE RESOLVED IN A BENCH TRIAL WITHOUT A JURY. WITH RESPECT TO THE
FOREGOING CONSENT TO JURISDICTION, LENDER HEREBY WAIVES ANY OBJECTION BASED ON
FORUM NON CONVENIENS, AND ANY OBJECTION TO VENUE OF ANY ACTION INSTITUTED
HEREUNDER AND CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS
DEEMED APPROPRIATE BY THE COURT. NOTHING IN THIS ARTICLE 8.4 SHALL AFFECT THE
RIGHT OF LENDER TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR
AFFECT THE RIGHT OF LENDER TO

                                       22


<PAGE>   92



BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS
OF ANY OTHER JURISDICTION.

     8.5 Execution in Counterparts; Severability. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which when taken together shall constitute one and the same
agreement. In case any provision in or obligation under this Agreement shall be
invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

     8.6 Joint and Several Liability. Each entity constituting Borrower hereby
unconditionally and absolutely guarantees to and for the Lender the due
performance, including without limitation the prompt payment when due or within
any applicable grace period, whether at stated maturity, by acceleration or
otherwise and at all times thereafter, of any and all Obligations of Borrower
owed to the Lender irrespective of (a) any lack of enforceability of any
Obligation, (b) any change of the time, manner, place of payment, or any other
term of any Obligation, (c) any exchange, release or non-perfection of any
collateral securing payment of any Obligation, (d) any law, regulation or order
of any jurisdiction affecting the genuineness, validity, or rights of the
Lender with respect to the Obligations or any instruments evidencing any of the
Obligations, or (e) any other circumstance which might otherwise constitute a
defense to or discharge of an entity constituting Borrower. Each entity
constituting Borrower agrees that its obligations hereunder are irrevocable;
that a separate action or actions may be brought and prosecuted against it
regardless of whether the other entity constituting Borrower is joined in any
such action or actions; and that it waives the benefit of any statute of
limitations affecting its liabilities hereunder or the enforcement hereof.

     Each entity constituting Borrower agrees that its obligations as a
guarantor shall not be impaired, modified, changed, released, or limited in any
manner whatsoever by any impairment, modification, change, release or
limitation of the liability of the other's estate in bankruptcy, resulting from
the operation of any present or future provision of the bankruptcy laws or
other similar statute, or from the decision of any court in a bankruptcy
proceeding.

     This is a continuing guarantee and shall remain in full force and effect
and be binding upon each entity constituting Borrower, their respective
successors and assigns until payment in full of all of the Obligations and no
partial payment hereunder shall entitle either of them, by subrogation or
otherwise, to any payment by the other out of its property.

     Each entity constituting Borrower hereby waives all notices of any
character whatsoever with respect to this guarantee and the Obligations,
including but not limited to notice of the acceptance hereof and reliance
hereon, of the present existence or future incurring of any Obligations, of the
amounts, terms and conditions thereof, and of any defaults thereon and further
waives the defenses of diligence, presentment for payment, protest, demand or
extensions of time for payment. Each entity constituting Borrower hereby
consents to the taking of, or failure to take, from time to time

                                       23


<PAGE>   93



without notice to it, any such action of any nature whatsoever with respect to
the Obligations and with respect to any rights against any person or persons or
in any property, including but not limited to any renewals, extensions,
modifications, postponements, compromises, settlements, substitutions, refusals
or failures to exercise or enforce, indulgences, waivers, surrenders, exchanges
and releases, and each such entity will remain fully liable hereon
notwithstanding any of the foregoing. Each entity constituting Borrower hereby
waives the benefit of all laws now or hereafter in effect in any way limiting
or restricting the liability of such entity hereunder, including without
limitation (a) all defenses whatsoever to such entity's liability hereunder
except the defense of payment made on account of the Obligations to the Lender
and such entity's liability hereunder; and (b) all right to stay of execution
and exemption of property in any action to enforce the liability of such entity
hereunder; and (c) all rights accorded such entity under any other statutory
provisions of any other applicable jurisdiction affecting the rights of the
Lender to enforce the obligations of such guarantee under this guarantee.

     Each entity constituting Borrower hereby consents and agrees that without
further notice to or assent from it, the time of payment of any or all of the
Obligations may be changed, any other term or condition relating to any or all
of the Obligations may be changed, the other entity constituting Borrower may
be discharged from any or all of the Obligations, any composition or settlement
relating thereto may be consummated and accepted, and that such entity will
remain bound upon this guarantee notwithstanding any or all of the foregoing.

     No failure on the part of the Lender to exercise, and no delay in
exercising, any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial exercise by the Lender of any right, power or
remedy preclude any other further exercise thereof or the exercise of any other
right, power or remedy. The rights and remedies provided herein shall be in
addition to and not exclusive of any rights or remedies provided at law or in
equity.

                                       24

     2. Creditor (as to (a) only) and Debtor (as to (a) and (b)) represent to
        Coast that:

        which, upon the terms and subject to the conditions therein, Creditor
        will make available to Debtor a line of credit up to the aggregate
        principal amount of $3,000,000.

     b. Debtor agrees, and Creditor consents and acknowledges, that the face of
        any and all Creditor Agreements shall be permanently and conspicuously
        marked with the following legend: "Subject to that certain
        Subordination and Intercreditor Agreement executed by and among Coast
        Business Credit, Dentsply International Inc., and New Image Industries,
        Inc. and Insight Imaging Systems, Inc., dated as of December 24, 1996"
        and, after being so marked, copies of said agreements and instruments
        shall be promptly delivered to Coast. Creditor shall mark all of its
        books and records in such manner as to indicate that the payment and
        enforcement of the Creditor Indebtedness and the Creditor Agreements
        are subject to the terms of this Agreement.

     3. Creditor and Debtor agree with Coast that:

     a. The Creditor Indebtedness shall be and hereby is subordinated to the
        extent provided herein, and the payment therefor shall be deferred if
        and when required pursuant to the terms hereof, to any and all rights,
        claims, demands, indebtedness, action or causes of action of any nature
        whatsoever that Coast may now have, or hereafter may have against
        Debtor with respect to the Coast Indebtedness.

     b. No scheduled payment of interest or principal shall be made prior to
        the expiration of the Forbearance Period. In addition, upon the
        commencement of a Blockage Period, (i) Creditor's right to receive any
        and all payments of interest and principal on the Creditor Indebtedness
        shall immediately cease, notwithstanding the terms of the Creditor
        Indebtedness, for a period commencing on the first day of such Blockage
        Period and continuing for the duration of such Blockage Period and (ii)
        Coast shall have no obligation to make loans to Debtor under the Coast
        Loan Documents from and after the commencement of such Blockage Period.

     c. The Creditor Indebtedness may be secured by security interests and
        liens in and upon the following assets of Debtor: such of the Coast
        Collateral which is described in the Creditor Agreements, provided,
        however, as set forth below, such security interests and liens in and
        upon the Coast Priority Collateral (as hereinafter defined) shall be at
        all times junior and subordinate to all security interests and liens of
        Coast in and upon the Coast Priority Collateral.

        As between Coast and Creditor, and notwithstanding the terms or time of
        granting or perfection of any security interest or lien, the time of
        filing or recording of any financing statements, assignments, or any
        other documents, instruments, or

                                       3


<PAGE>   102



        agreements under the Uniform Commercial Code or any other applicable
        law, Coast shall have a first priority security interest in and lien
        upon the Coast Collateral (the "Coast Priority Collateral"). The lien
        and security interest priority provided herein shall not be altered or
        otherwise affected by any amendment, modification, supplement,
        extension, renewal, restatement, or refinancing of any of the Creditor
        Indebtedness or of any of the Coast Indebtedness, nor by any action or
        inaction which Coast or Creditor may take or fail to take in respect of
        any of the respective collateral.

     d. If a Triggering Event has occurred and a Blockage Period has commenced,
        Creditor agrees that it will not commence, prosecute or participate in
        any administrative, legal or equitable action against Debtor or any of
        the Coast Collateral or any other assets of the Debtor, or in any
        administrative, legal, or equitable action that might adversely affect
        Debtor or its interests, without Coast's prior written consent, which
        consent may be withheld in Coast's sole discretion for any reason,
        until the sooner to occur of (i) if a Triggering Event has occurred,
        the first day after the expiration of the Blockage Period with respect
        thereto, so long as on such date Coast has not yet commenced
        enforcement of its rights and remedies with respect to the Coast
        Priority Collateral; provided that if Coast has commenced enforcement
        of its rights or remedies, Creditor may enforce its rights and remedies
        at the end of the Blockage Period other than foreclosing on or
        collecting any of the Coast Priority Collateral, and (ii) the date that
        the Coast Loan Documents have been terminated and all of the Coast
        Indebtedness has been paid in full; provided, however, Creditor shall
        have the right (subject and subordinate to the Coast Loan Documents) to
        file a claim in any voluntary or involuntary bankruptcy or insolvency
        action or proceeding of Debtor.

     e. Creditor shall give Coast a copy of any notice(s) of any default or
        event of default under the Creditor Agreements or of any actions which
        Creditor intends to take with respect thereto, concurrently with the
        giving of such notice(s) to Debtor. Coast shall give Creditor a copy of
        any notice(s) of any default or event of default under the Coast Loan
        Documents or of any actions which Coast intends to take with respect
        thereto, concurrently with the giving of such notice(s) to Debtor;
        provided that the failure of Creditor or Coast to give such notice
        shall not create any liability of such party to the other or affect
        either party's rights under this Agreement.

     4. If Creditor, in violation of this Agreement, shall commence, prosecute
or participate in any suit, action or proceeding against Debtor whenever
prohibited by the terms hereof, Debtor may interpose as a defense or dilatory
plea the making of this Agreement and Coast may intervene and interpose such
defense or plea in Coast's name or in the name of Debtor. If Creditor shall
attempt to enforce any of the Creditor Agreements whenever prohibited by the
terms hereof, Coast or Debtor may by virtue of this Agreement restrain the
enforcement thereof in Coast's name or in the name of Debtor. If Creditor shall
obtain any assets of Debtor or the proceeds thereof whenever prohibited by the
terms hereof as a result of any administrative, legal, or equitable action, or
otherwise, Creditor agrees to forthwith pay, deliver, and assign to Coast any
such assets or proceeds for application upon

                                       4


<PAGE>   103



the Coast Indebtedness.

     5. Except for scheduled payments of interest and principal as and to the
extent permitted by the terms of Section 3.b of this Agreement, Debtor agrees
with Coast that it will not, without Coast's prior written consent (which may
be withheld for any reason), pay to Creditor any sum on account of the Creditor
Indebtedness provided that notwithstanding the foregoing, Debtor may, following
the date on which the Letter of Intent is terminated, make principal
prepayments to Creditor so long as (i) no Blockage Period is then in effect,
(ii) no Event of Default has occurred and is continuing (under the criteria set
forth in Section 1 hereof under "Triggering Event") and (iii) Debtor has excess
borrowing availability pursuant to the borrowing formulas in the Coast
Agreement of not less than $100,000 both during the ten days prior to the
contemplated payment and on the date of payment after taking into account the
proposed payment.

     6. Coast may grant extensions of the time of payment or performance of the
Coast Indebtedness and make compromises and settlements with Debtor and all
other persons with respect to the Coast Indebtedness, and release all or any
portion of the Coast Priority Collateral (subject to an obligation to use its
best efforts to realize the maximum proceeds from the disposition thereof), all
without the consent of Debtor or Creditor and all without affecting the
agreements of Creditor or Debtor hereunder.

     7. Coast hereby consents to the Creditor Indebtedness subject to the terms
and conditions of this Agreement.

     8. Coast agrees that the subordinations and relative priority agreements
set forth above are expressly conditioned upon the non-voidability and
perfection of the security interest to which another security interest is
subordinated and if the security interest to which another interest is
subordinated is not perfected or is voidable for any reason, then the
subordination provided for herein shall not be effective as to the particular
collateral; provided, however, that Creditor agrees that it shall not take any
action to void or attempt to void a security interest granted in favor of
Coast; provided further, however, notwithstanding anything to the contrary
contained herein, nothing shall prevent Creditor from serving on any creditors'
committee or filing a claim, or otherwise participating, in any voluntary or
involuntary bankruptcy or insolvency action or proceeding of Debtor.

     9. If, at any time hereafter, Coast shall, in Coast's own judgment,
determine to discontinue the extension of credit to Debtor in accordance with
the terms of the Coast Loan Documents, Coast may do so. This Agreement shall
continue in full force and effect until the Coast Loan Documents have been
terminated and all of the Coast Indebtedness has been paid in full. Creditor
and Debtor agree that, if at any time all or any part of any payment previously
applied by Coast to the Coast Indebtedness is or must be returned by Coast, or
recovered from Coast for any reason (including the order of any bankruptcy
court), this Agreement shall automatically be reinstated to the same effect as
if the prior application had not been made, and, in addition, Debtor hereby
agrees to indemnify Coast against, and to save and hold Coast harmless from any
required return by

                                       5


<PAGE>   104



Coast or recovery from Coast, of any of such payments because of its being
deemed preferential under applicable bankruptcy, receivership or insolvency
laws, or for any other reason.

     10. This Agreement shall be binding upon the successors and assigns of
Creditor and Debtor, and shall inure to the benefit of the successors and
assigns of Coast.

     11. All notices, demands, requests, consents, approvals, declarations or
other communications from one party hereto to another relating to this
Agreement shall be in writing and shall be delivered either in person, with

mail, postage prepaid, or by facsimile, addressed as follows:

DENTSPLY International Inc.

     Re: New Image
         ---------

Gentlemen:

     Reference is made to that certain Amended and Restated Loan and Security
Agreement dated May 22, 1996, as amended ("Loan Agreement") among Coast
Business Credit, a division of Southern Pacific Thrift & Loan Association
("Coast") on the one hand and New Image Industries, Inc. and Insight Imaging
Systems, Inc. (New Image Industries, Inc. and Insight Imaging Systems, Inc. is
hereinafter collectively referred to as, "Borrower") on the other hand.
Borrower is in violation of its covenant under the Loan Agreement to be and
continue to be solvent ("Solvency Covenant"). Coast has waived compliance by
Borrower with the Solvency Covenant through January 1, 1997.

     Borrower has advised Coast that it proposes to enter into a letter of
intent with DENTSPLY International Inc. (the "Letter of Intent") with respect
to the acquisition of Borrower by a wholly-owned subsidiary of DENTSPLY
International Inc. ("DENTSPLY"). That Letter of Intent provides, among other
things, for DENTSPLY to loan to Borrower not less than $2,500,000 and not more
than $3,000,000 pending the negotiation and possible execution and closing of a
definitive merger agreement as contemplated in the Letter of Intent. In turn,
DENTSPLY requires a security interest in the assets of Borrower, junior only to
the security interest of Coast. In order for Borrower to provide the security
interest to DENTSPLY, Borrower has requested Coast to purchase the claim of
Mercury Partners, LLC ("Mercury") in the principal amount of $500,000. Borrower
confirms that the claim of Mercury Partners, LLC in the principal amount of
$500,000 is due and owing without offset, counterclaim, defense or offset.

     In consideration of the above, including without limitation, the agreement
of DENTSPLY to loan not less than $2,500,000 to Borrower, Coast hereby agrees
to forbear from exercising any of its default rights and remedies in connection
with the violation of the Solvency Covenant and the violation of any and all
other covenants of which Borrower may be in breach as of the date hereof
whether contained in the Loan Agreement or in the loan documents assigned to
Coast by Mercury (the "Mercury Agreement"), and any and all other covenants,
whether contained in the Loan Agreement or in the Mercury Agreement documents
assigned to Coast by Mercury, which may occur subsequent to the date hereof
through the earlier of March 25, 1997 or (b) the date on which the Letter of
Intent terminates other than by execution of a definitive merger agreement as
contemplated therein ("Forbearance Period"). If for any reason the Letter of
Intent terminates, DENTSPLY agrees to give Coast prompt written notice of such
termination. Notwithstanding the foregoing, Coast is not forbearing from any
default arising from the failure of Borrower to make any required payment to
Coast of principal or interest due and payable after the date hereof (other
than a payment which may be or become due and payable as a result of a default
of Borrower to comply with the Solvency Covenant or any other non-payment
covenant). Nothing


<PAGE>   109


herein shall affect the right of Coast to exercise any and all default rights
and remedies after the expiration of the Forbearance Period.

     DENTSPLY confirms that in the event of a closing of a definitive merger
agreement as set forth in the Letter of Intent, DENTSPLY will cause the claim
of Coast against Borrower (including the claim of Mercury purchased by Coast)
to be paid in full, unless Coast shall agree otherwise in writing.

     Coast acknowledges that concurrent with the execution of the Letter of
Intent, Borrower and DENTSPLY will enter into a credit agreement which will
provide for, among other things, the granting of a security interest in favor
of DENTSPLY junior to the security interest of Coast. Coast hereby consents to
the execution by Borrower of the credit agreement and the performance of its
obligations thereunder.

     The obligations of Coast under this letter agreement are conditioned upon
the concurrent execution of a Subordination and Intercreditor Agreement among
DENTSPLY, Borrower and Coast in form and substance satisfactory to Coast and
confirmation that $2,500,000 will be loaned forthwith by DENTSPLY to Borrower.


                                        Very truly yours,

                                        Coast Business Credit

Mr. Dewey Edmunds, President
New Image Industries, Inc.
2283 Cosmos Court
Carlsbad, CA  92009

Gentlemen:

This will confirm our discussions with respect to the proposed acquisition of
New Image Industries, Inc., a Delaware corporation ("New Image"), by DENTSPLY
International Inc., a Delaware corporation ("Dentsply").

1. Structure and Price. Subject to the conditions set forth below, the
transaction will be accomplished by means of either (i) a tender offer (the
"Tender Offer") to be made by a wholly-owned subsidiary of Dentsply (the
"Acquisition Subsidiary") for all of the issued and outstanding shares of
Common Stock of New Image (the "New Image Common Stock"), conditioned on the
tender of at least 51% of such shares, for a price of $2.00 per share in cash
(the "Offer Consideration"), and, following completion of the Tender Offer, the
merger of Acquisition Subsidiary with and into New Image pursuant to which each
share of the outstanding Common Stock of New Image then owned by Acquisition
Subsidiary will be exchanged for the Offer Consideration, and each option,
warrant and other right to acquire a share of the Common Stock of New Image
will be exchanged for the Offer Consideration less the exercise price of such
option, warrant or right; or (ii) an all-cash merger of Acquisition Subsidiary
with and into New Image for the price set forth above.

2. Certain Fundamental Conditions. Consummation of the proposed acquisition or
the proposed tender will be subject to the following fundamental conditions:

                  (i) There are on the date hereof and there will be, at all
                  times between the date hereof and the closing, no more than
                  5,479,908 outstanding shares of New Image Common Stock (plus
                  any shares issued upon the exercise of options or other
                  rights outstanding on the date hereof as set forth below),
                  and no outstanding shares or rights to acquire any other
                  class of New Image capital stock, and outstanding stock
                  options,

<PAGE>   111


New Image Industries, Inc.
Page 2
December 24, 1996

                  warrants and other rights to acquire no more than 2,045,201
                  shares of New Image Common Stock, and no more than 950,000 of
                  such options, warrants and rights having an exercise price of
                  less than $2.00, and the average of the exercise prices of
                  such 950,000 options, warrants and other rights being not
                  less than approximately $1 9/16;

                  (ii) due diligence review, to Dentsply's sole satisfaction,
                  by Dentsply and its legal and financial advisors, of the
                  business, assets, operations and liabilities of New Image,
                  including, without limitation, environmental conditions and
                  contingencies, pending or threatened patent and other
                  litigation matters, accounting matters, employee benefits and
                  other contingent liabilities;

                  (iii) negotiation and execution of definitive documentation
                  mutually acceptable in form and substance;

                  (iv) approval of such documentation by the Boards of
                  Directors of Dentsply and New Image;

                  (v) negotiation and execution of a Stockholder Agreement
                  between Dentsply and each of the directors and officers of
                  New Image who collectively own approximately 13.8% of the
                  outstanding New Image Common Stock and options (each, a
                  "Stockholder"), pursuant to which, among other things, such
                  Stockholder will agree to tender his or her shares of New
                  Image Common Stock in the Tender Offer or, if the acquisition
                  is accomplished by means of a merger without a Tender Offer
                  to vote such shares in favor of such merger, as the case may
                  be, and, pending consummation of the proposed acquisition,
                  not to sell or otherwise transfer shares of New Image Common
                  Stock owned of record or beneficially by him or her;

                  (vi) receipt of all approvals, consents or waivers from third
                  parties, the absence of which would, in Dentsply's reasonable
                  judgment, be reasonably likely to be materially adverse to
                  New Image or to the transactions contemplated by this letter;

                  (vii) receipt of all material regulatory and governmental
                  approvals and compliance with all applicable regulatory or
                  governmental requirements;


<PAGE>   112


New Image Industries, Inc.
Page 3
December 24, 1996

                  (viii) the business and operations of New Image are conducted
                  in the ordinary course between the date hereof and the
                  closing date; (ix) if the proposed acquisition is
                  accomplished by means of a Tender Offer, tender of no fewer
                  than the number of shares representing at least 51% of the
                  issued and outstanding shares of New Image Common Stock;

                  (x) there having been no dividends or other distributions
                  paid with respect to the New Image Common Stock, and no
                  increases in compensation, bonuses, loans or other payments
                  outside the ordinary course made to any officers, directors
                  or management employees of New Image, and no consulting,
                  brokers', finders' or investment banking or advisory fees
                  paid to any director or any person affiliated with New Image
                  or affiliated with any of its directors, officers or
                  management employees;

                  (xi) negotiation and execution of an employment agreement
                  with Dewey F. Edmunds, mutually acceptable in form and
                  substance;

                  (xii) the definitive documentation referred to in clause
                  (iii) above shall include covenants from Dentsply to continue
                  complying with the agreements covered by Paragraph 5 hereof
                  for the time period set forth therein; and

                  (xiii) the conditions set forth in subparagraphs (ii), (iii)
                  and (v) of this Paragraph 2 will be satisfied or waived at
                  the time the parties enter into definitive documentation.

3. Negotiation in Good Faith. Dentsply and New Image will negotiate in good
faith to execute definitive documentation evidencing the proposed transaction
as promptly as practicable and will cooperate fully with each other in
preparing all such documentation, obtaining all necessary approvals, consents
or waivers from third parties and taking reasonable steps to comply with all
governmental and regulatory requirements.

4. Regulatory Filings. Dentsply and New Image will cooperate in making as
promptly as practicable after the date hereof all filings and seeking all
approvals which may be determined to be necessary in connection with the
transactions contemplated hereby, including, without limitation, filings under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

5. Standstill. In the event that the proposed acquisition is not consummated,
Dentsply hereby agrees that, for a period of one year from the date of this
Agreement, unless New Image shall (i)


<PAGE>   113


New Image Industries, Inc.
Page 4

otherwise agree in writing, (ii) apply for or consent to the appointment of a
receiver, trustee or liquidator of itself or of its property, (iii) make a
general assignment for the benefit of creditors, (iv) be adjudicated a bankrupt
or insolvent, (v) file a voluntary petition in bankruptcy, or a petition or
answer seeking reorganization or an arrangement with creditors to take
advantage of any insolvency law, or an answer admitting the material
allegations of a bankruptcy, reorganization or insolvency petition filed
against it, (vi) take corporate action for the purpose of effecting any of the
foregoing, (vii) have an order for relief entered against it in any proceeding
under the United States Bankruptcy Code, (viii) have an order, judgment or
decree entered, without the application, approval or consent of New Image, by
any court of competent jurisdiction, approving a petition seeking
reorganization of New Image or appointing a receiver, trustee or liquidator of
New Image or of all or a substantial part of its assets, and such order,
judgment or decree shall continue unstayed and in effect for a period of 60
consecutive days, or (ix) solicit Acquisition Proposals (as defined in
Paragraph 7 hereof), neither Dentsply nor any of its affiliates (as such term
is defined under the Securities Exchange Act of 1934, as amended (the "1934
Act")) will in any manner, directly or indirectly, (a) effect or seek, offer or
propose (whether publicly otherwise) to effect, offer or participate in (A) any
acquisition of any securities (or beneficial ownership thereof) or assets of
New Image or any of its subsidiaries; (B) any tender or exchange offer, merger
or other business combination involving New Image or any of its subsidiaries;
(C) any recapitalization, restructuring, liquidation, dissolution or other
extraordinary transaction with respect to New Image or any of its subsidiaries;
or (D) any "solicitation" of "proxies" (as such terms are used in the proxy
rules of the Securities and Exchange Commission) or consents to vote any voting
securities of New Image; (b) form, join or in any way participate in a "group"
(as defined under the 1934 Act) formed to accomplish any of the foregoing; (c)
otherwise act, alone or in concert with others, to seek to control the
management or Board of Directors of New Image; (d) take any action which might
force New Image to make a public announcement regarding any of the types of
matters set forth in (a) above; or (e) enter into any discussions or
arrangements with any third party with respect to any of the foregoing.
Dentsply also agrees during such period not to request New Image (or its
directors, officers, employees or agents), directly or indirectly, to amend or
waive any provision of this paragraph (including this sentence).

6. Information. During the period from the date hereof and until the earlier of
the expiration of this letter as provided in Paragraph 11 below or its prior
termination, Dentsply shall be provided full opportunity to examine the
financial records and reports of New Image in connection with its due diligence
investigation (including, without limitation, the work papers of independent
certified public accountants, the financial statements for the fiscal year
ended June 30, 1996 and financial projections for fiscal year 1997), leases,
properties, books of account, corporate records, legal opinions and
litigation-related documents and other materials and information of any kind
relating to the business, assets, operations and liabilities of New Image, and
the officers and


<PAGE>   114


New Image Industries, Inc.
Page 5
December 24, 1996

employees of New Image shall cooperate with such examination. All information
delivered pursuant to this letter shall be subject to the Confidentiality
Agreement of even date herewith executed by the parties.

7. Exclusive Dealing. From the date hereof and until the earlier of the
expiration of this letter as provided in Paragraph 11 below or its prior
termination, New Image agrees that neither it nor any of its subsidiaries,
officers, directors, or the directors and officers of its subsidiaries, nor any
of its other affiliates (each, an "Affiliate") shall, and New Image shall cause
its and its respective subsidiaries' and Affiliates' employees, agents and
representatives (including, without limitation, any investment banking, legal
or accounting firm retained by New Image or any of its subsidiaries or
Affiliates and any individual member or employee of the foregoing) (each, an
"Agent") not to (a) initiate, solicit or seek, directly or indirectly, any
inquiries or the making or implementation of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders or any of them)
with respect to a merger, acquisition, consolidation, recapitalization,
liquidation, dissolution or similar transaction involving, or any purchase of
all or a substantial portion of the assets or any equity securities of, it or
any of its subsidiaries (any such proposal or offer being hereinafter referred
to as an "Acquisition Proposal"), or (b) engage in any negotiations concerning,
or provide any confidential information or data to, or have any discussions
with, any person relating to an Acquisition Proposal, or (c) otherwise
cooperate in any effort or attempt to make, implement or accept an Acquisition
Proposal; provided, however, that New Image may, if it receives an Acquisition
Proposal which was not directly or indirectly initiated, solicited or otherwise
sought by New Image or by any of the individuals or entities referred to in the
first sentence of this Paragraph 7, and which in the written opinion of its
outside financial advisor, is superior from a financial point of view to the
transactions contemplated by this letter (a "Superior Acquisition Proposal"),
respond to such Superior Acquisition Proposal, if New Image has received a
written opinion of its outside counsel that such response is required in order
to satisfy the fiduciary duties imposed under applicable law on its Board of
Directors. New Image shall immediately cease and cause to be terminated any
existing activities, including discussions or negotiations with any parties,
conducted heretofore with respect to any of the foregoing and shall take the
necessary steps to inform the individuals and entities referred to in the first
sentence hereof of the obligations undertaken in this Paragraph 7. If New Image
or any of its Affiliates or Agents has provided any person (other than
Dentsply) with any confidential information or data relating to an Acquisition
Proposal, it shall request the immediate return thereof. New Image shall notify
Dentsply immediately if any inquiries, proposals or offers related to an
Acquisition Proposal are received by, any confidential information or data is
requested from, or any negotiations or discussions related to an Acquisition
Proposal are sought to be initiated or continued with, it or any individual or
entity referred to in the first sentence of this Paragraph 7, and of the terms
and other details of any such Acquisition Proposal or request.

8. Expenses. Except as provided below, each of New Image and Dentsply will
separately bear its own expenses, including the fees and disbursements of
counsel, investment bankers and accountants, incurred in connection with this
letter of intent and the transactions contemplated hereby. If New Image or any
Affiliate or Agent of New Image shall fail to fulfill the obligations under
Paragraph 7 above, and shall sell, or enter into an agreement which
contemplates the sale of, all or any material portion of the assets or equity

        WHEREAS, the Parties recognize that they may be required to disclose
confidential information in such business discussions:

        NOW THEREFORE, in consideration of the above and the mutual covenants

obligations of this Agreement.

        3.      All Confidential Information exchanges between the Parties

<PAGE>   119
        (d)     shall be treated by the receiving Party with the same degree of
care to avoid disclosure to any third Party as is used with respect to the
receiving Party's own information of like importance which is to be kept
confidential; 

        (e)     shall not be used by the receiving Party for its own purposes
of any other purpose except the purpose set forth above, except as otherwise
expressly stated herein, without the express written permission of the
disclosing Party; and

        (f)     shall remain the property of and be returned to the disclosing
Party (along with all copies thereof) within thirty (30) days of receipt by the
receiving Party of a written request from the disclosing Party setting forth the
Confidential Information to be returned, or shall be destroyed and confirmed by
a certificate attesting the same.

        4.      The obligation of Paragraph 3 shall not apply however to any

Information shall terminate three (3) years from the date of receipt by the
receiving Party or at such earlier time when such Confidential Information
enters the public domain pursuant to Section 4(a) above.

        6.      Either party shall have the right to refuse to accept any
information under this Agreement and nothing herein shall obligate either Party
to disclose any particular information to the other party.

        7.      The parties hereto shall not be obligated to compensate each

further agreement with the other except as it, in its sole judgment, may deem
advisable.  It is understood that no patent, copyright, trademark or other
proprietary right or license is granted by this Agreement.  The disclosure of
Confidential information and material which may accompany the disclosure shall
not result in any obligation to grant the receiving Party rights therein.

and delivered in the State of California, and agree that the laws of the State
of California shall govern the interpretations and enforcement, and that any
legal action arising out of or in conjunction with this Agreement or any breech
thereof shall be brought and prosecuted in an appropriate court of competent

agreement of the Parties and supersedes all prior communications, agreements
and understandings relating to the subject matter hereof.  The provisions of
this Agreement may not be modified, amended, nor waived, except by a written
instrument duly executed by both Parties.

        IN WITNESS HEREOF, the Parties hereto, intending to be legally bound,

                          AGREEMENT AND PLAN OF MERGER


         THIS AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of
January 27, 1997, is by and among DENTSPLY International Inc., a Delaware
corporation ("Parent"), Image Acquisition Corp., a Delaware corporation and
wholly owned subsidiary of Parent ("Merger Sub"), and New Image Industries,
Inc., a Delaware corporation (the "Company").

                              W I T N E S S E T H:

         WHEREAS, the respective Boards of Directors of Parent, Merger Sub and
the Company have approved the acquisition of the Company by Parent upon the
terms and subject to the conditions set forth in this Agreement;

         WHEREAS, in furtherance of such acquisition, Parent proposes to cause
Merger Sub to make a tender offer (as it may be amended from time to time as
permitted under Section 1.1 of this Agreement, the "Offer") to purchase all the
issued and outstanding shares of Common Stock, par value $.001 per share, of
the Company (the "Company Common Stock,"  the outstanding shares of Company
Common Stock being hereinafter referred to as the "Shares"), at a purchase
price of  $2.00 per share (the "Offer Price"), net to the seller in cash,
without interest thereon, upon the terms and subject to the conditions set
forth in this Agreement; and the Board of Directors of the Company has adopted
resolutions approving the Offer and the Merger (as defined below), recommending
that the Company's stockholders accept the Offer;

         WHEREAS, each of the respective Boards of Directors of Parent, Merger
Sub and the Company has approved the Offer and the merger of Merger Sub with
and into the Company (the "Merger") upon the terms and subject to the
conditions set forth in this Agreement, whereby each issued and outstanding
share of Company Common Stock, other than shares owned directly or indirectly
by Parent or the Company and "Dissenting Shares" (as defined in Section
2.8(d)), will be converted into the right to receive the Offer Price;

         WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent, Merger Sub and each
executive officer (as defined in Rule 3b-7 promulgated under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")) and director of the
Company who, in each case, owns Shares or options or warrants to acquire shares
of the Company Common Stock and The William W. Stevens and Virda J. Stevens
Trust, a stockholder of the Company (collectively, the "Stockholder Parties"),
are entering into separate stockholder agreements (the "Stockholder
Agreements"), pursuant to which each such Stockholder Party  is agreeing to
tender all Shares owned by such person in the Offer, upon the terms and subject
to the conditions set forth in such Stockholder Party's respective Stockholder
Agreement; and

         WHEREAS, Parent, Merger Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger and also to prescribe various conditions to the Offer and
the Merger;


<PAGE>   126

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, intending to be legally bound hereby, Parent,
Merger Sub and the Company hereby agree as follows:


                             ARTICLE 1 -- THE OFFER

         1.1      The Offer.

                  (a)      Subject to the conditions set forth in the Appendix
hereto, as promptly as practicable but in no event later than five business
days after the date of the public announcement by Parent and the Company of the
execution of this Agreement, Merger Sub shall, and Parent shall cause Merger
Sub to, commence (within the meaning of Rule 14d-2 under the Exchange Act),
the Offer for any and all Shares at a price of $2.00 per share net to the
seller in cash, without interest thereon, and, subject to the conditions set
forth in the Appendix, consummate the Offer in accordance with its terms.  The
Offer shall be made by means of an Offer to Purchase having the conditions set
forth in the Appendix (any of which may be waived by Merger Sub or Parent in
its sole discretion).  The obligations of Merger Sub to commence the Offer and
to accept for payment and to pay for any Shares validly tendered on or prior to
the expiration of the Offer and not withdrawn shall be subject only to the
conditions set forth in the Appendix.

                  (b)      Parent will not, and will cause Merger Sub not to,
without the prior written consent of the Company (which consent may be withheld
for any reason), decrease the price per Share, or change the form of
consideration payable, in the Offer, decrease the number of Shares sought in
the Offer, change the conditions to the Offer from those contained in the
Appendix hereto, impose additional conditions to the Offer, or amend any
material term of the Offer in a manner adverse to the holders of the Shares.
Subject to the terms and conditions of the Offer and this Agreement, Merger Sub
shall, and Parent shall cause Merger Sub to, accept for payment, and pay for,
all Shares validly tendered and not withdrawn pursuant to the Offer that Merger
Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer
as soon as practicable after the expiration of the Offer.

         1.2      Parent Action; Tender Offer Documents.  As soon as
practicable but not later than the date of commencement of the Offer, Parent
shall file or cause to be filed with the Securities and Exchange Commission
(the "SEC") a Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1").
The Schedule 14D-1 filed with the SEC, which shall contain the Offer to
Purchase and a related letter of transmittal and summary advertisement (such
Schedule 14D-1 and the documents included therein pursuant to which the Offer
will be made, together with any supplement or amendment thereto, are hereafter
referred to as the "Offer Documents") shall comply as to form in all material
respects with the applicable provisions of the Exchange Act and the rules and
regulations promulgated thereunder, and shall not contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements made therein, in light of the
circumstances under which they were made, not misleading; provided, however,
that the foregoing representation shall not apply with respect to the accuracy
of information furnished in

                                       2
<PAGE>   127

writing by the Company specifically for inclusion in the Offer Documents or
which is taken, after consultation with the Company, from reports filed by the
Company under the Exchange Act (provided that such information has not been
superseded by information contained in reports filed by the Company under the
Exchange Act subsequent thereto), which accuracy shall be the sole
responsibility of the Company.  Parent, Merger Sub and the Company each agrees
promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that it shall have become false or misleading in
any material respect, and Parent and Merger Sub further agree to take all steps
necessary to cause the Schedule 14D-1 as so corrected to be filed with the SEC
and the Offer Documents as so corrected to be disseminated to holders of
Shares, in each case as and to the extent required by applicable Federal
securities laws. The Company and its counsel shall be given reasonable
opportunity to review the Offer Documents prior to their filing with the SEC.
Parent and Merger Sub agree to provide the Company and its counsel in writing
any comments Parent, Merger Sub or its counsel may receive from the SEC or its
staff with respect to the Offer Documents promptly after receipt of such
comments.

         1.3      Company Action.

                  (a)      The Company hereby approves of and consents to the
Offer and represents that the Board of Directors of the Company, at a meeting
duly called and held, duly and unanimously adopted resolutions approving this
Agreement, the Offer and the Merger, determining that the terms of the Offer
and the Merger are fair, from a financial point of view, to, and in the best
interests of, the Company's stockholders and recommending that the Company's
stockholders approve and adopt this Agreement, and that the Company's
stockholders accept the Offer and tender their Shares pursuant to the Offer,
provided, however, that any such recommendation may be amended, withdrawn or
modified in accordance with the provisions of Section 6.5(b).  The Company
represents that its Board of Directors has received the opinion of Cleary Gull
Reiland & McDevitt Inc. ("Cleary Gull") to the effect that the proposed
consideration 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, and a
complete and correct signed copy of such opinion has been delivered by the
Company to Parent.  The Company understands that, concurrently with the
execution of this Agreement, each of the Company's directors and officers
intends to execute a Stockholder Agreement with Parent and/or Merger Sub and
intends to tender all Shares owned by such person pursuant to the Offer.  The
Company hereby approves of and consents to the execution by each Stockholder
Party of such Stockholder Party's Stockholder Agreement and the consummation of
the transactions contemplated thereby, including the tender of such Shares, and
represents that the Board of Directors of the Company, at a meeting duly called
and held, duly and unanimously adopted resolutions approving the execution of
the Stockholder Agreements and the consummation of the transactions
contemplated thereby.

                  (b)      On the date the Offer Documents are filed with the
SEC, the Company shall file with the SEC and mail to the holders of Shares a
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which shall reflect the recommendations described in Section 1.3(a).  The
Company agrees that the Schedule 14D-9, including all amendments and
supplements thereto, shall comply as to form in all material respects with the
applicable provisions of the Exchange Act and the rules and regulations
promulgated thereunder, and shall not contain any

                                       3
<PAGE>   128

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;
provided, however, that the foregoing representation shall not apply with
respect to the accuracy of information furnished in writing by Parent
specifically for inclusion in the Schedule 14D-9 or taken from reports, after
consultation with the Company, filed by Parent under the Exchange Act (provided
that such information has not been superseded by information contained in
reports filed by Parent under the Exchange Act subsequent thereto).  The
Company, Parent and Merger Sub each agrees promptly to correct any information
provided by it for use in the Schedule 14D-9 if and to the extent that it shall
have become false or misleading in any material respect, and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
amended or supplemented to be filed with the SEC and disseminated to the
Company's shareholders, in each case as and to the extent required by
applicable Federal securities laws.  Parent and Merger Sub and their counsel
shall be given reasonable opportunity to review the Schedule 14D-9 prior to its
filing with the SEC.  The Company agrees to provide Parent and its counsel in
writing any comments the Company or its counsel may receive from the SEC or its
staff with respect to the Schedule 14D-9 promptly after receipt of such
comments.

                  (c)      The Company will promptly furnish Parent or cause
Parent to be furnished with mailing labels containing the names and addresses
of the record holders of Shares 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 the Company's possession or control regarding the
beneficial owners of Shares, and shall furnish Parent with such additional
information and assistance as Parent may reasonably request to communicate the
Offer to the stockholders of the Company.


                            ARTICLE 2 -- THE MERGER

         2.1      The Merger.  Upon the terms and subject to the conditions of
this Agreement and in accordance with the Delaware General Corporation Law (the
"DGCL"), at the "Effective Time" (as defined in Section 2.2 hereof), Merger Sub
shall be merged with and into the Company in the Merger, the separate existence
of Merger Sub (except as may be continued by operation of law) shall cease, and
the Company shall continue as the surviving corporation following the Merger
(the "Surviving Corporation").  Notwithstanding the foregoing, Parent may elect
at any time prior to the Merger to merge the Company with and into Merger Sub,
instead of merging Merger Sub with and into the Company, in which event the
parties agree to execute an appropriate amendment to this Agreement to reflect
the foregoing.

         2.2      Effective Time. Upon the terms and subject to the conditions
hereof, the parties hereto will file a Certificate of Merger with the Secretary
of State of the State of Delaware, in such form as may be required by, and
executed in accordance with, the DGCL.  The Merger shall become effective at
such time as such document is so filed or at such time as is set forth in the
Certificate of Merger, if different, which time is hereinafter referred to as
the "Effective Time."


                                       4
<PAGE>   129

         2.3      Closing.  The closing of the Merger shall take place at the
offices of Morgan, Lewis & Bockius LLP, One Oxford Centre, Pittsburgh, PA 15219
at 10:00 a.m., Eastern Time, on a date (the "Closing Date") to be specified by
the parties, which shall be no later than the second business day after the
satisfaction or waiver of the conditions set forth in Article 7.

         2.4      Effects of the Merger.  The Merger shall have the effects set
forth in the applicable provisions of the DGCL and this Agreement.

         2.5      Certificate of Incorporation; By-Laws.  The Certificate of
Incorporation and By-Laws of Merger Sub at the Effective Time shall be the
Certificate of Incorporation and By-Laws of the Surviving Corporation until
amended as provided therein and under the DGCL.

         2.6      Directors and Officers of the Surviving Corporation.  The
directors and officers of Merger Sub at the Effective Time shall, from and
after the Effective Time, be the directors and officers of the Surviving
Corporation until their successors shall have been duly elected or appointed
and qualified or until their earlier death, resignation or removal in
accordance with the Surviving Corporation's Certificate of Incorporation and
Bylaws.

         2.7      Taking of Necessary Action; Further Action.  If, at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full rights and title to and possession of all assets, properties, rights,
privileges, immunities and franchises of either the Company or Merger Sub, the
officers and directors of each such corporation are fully authorized in the
name of such corporation or otherwise to take, and shall take, all such lawful
and necessary action.

         2.8      Conversion of Securities.  At the Effective Time, by virtue
of the Merger and without any action on the part of Merger Sub, the Company or
the holder of any of the securities of the Company or Merger Sub:

                  (a)      Subject to Section 2.8(d) hereof, each Share issued
and outstanding immediately prior to the Effective Time (other than Shares to
be canceled pursuant to Section 2.8(b) hereof), shall be canceled and
extinguished and be converted into and represent the right to receive $2.00 in
cash, without interest (the "Merger Consideration").  All such Shares, by
virtue of the Merger and without any action on the part of the holders thereof,
shall no longer be outstanding and shall be canceled and retired and shall
cease to exist, and each holder of a certificate representing any such Shares
shall thereafter cease to have any rights with respect thereto, except the
right to receive the Merger Consideration for such Shares upon the surrender of
such certificate in accordance with Section 2.9.

                  (b)      Each Share issued and outstanding immediately prior
to the Effective Time and held in the treasury of the Company or owned by
Parent or any direct or indirect subsidiary of Parent (including Merger Sub)
shall be canceled and retired and no payment shall be made with respect
thereto.


                                       5
<PAGE>   130

                  (c)      Each share of Common Stock, par value $.01 per
share, of Merger Sub 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.

                  (d)      Notwithstanding anything in this Agreement to the
contrary, any issued and outstanding Shares held by a person (a "Dissenting
Stockholder") who objects to the Merger and complies with all the provisions of
the DGCL concerning the right of holders of Shares to dissent from the Merger
and require appraisal of their Shares ("Dissenting Shares") shall not be
converted as described in Section 2.8(a) but shall become the right to receive
such consideration as may be determined to be due to such Dissenting
Stockholder pursuant to the laws of the State of Delaware.  If, after the
Effective Time, such Dissenting Stockholder withdraws his demand for appraisal
or fails to perfect or otherwise loses his right of appraisal, in any case
pursuant to the DGCL, his Shares shall be deemed to be converted as of the
Effective Time into the right to receive the Merger Consideration.  The Company
shall give Parent (i) prompt notice of any demands for appraisal of Shares
received by the Company and (ii) the opportunity to participate in and direct
all negotiations and proceedings with respect to any such demands.  The Company
shall not, without the prior written consent of Parent, make any payment with
respect to, or settle, offer to settle or otherwise negotiate, any such
demands.

         2.9      Exchange of Certificates.

                  (a)      Prior to the Effective Time, Parent shall select a
bank or trust company to act as paying agent (the "Paying Agent") for the
payment of the Merger Consideration upon surrender of certificates representing
Shares.

                  (b)      Parent shall, or shall cause the Surviving
Corporation to, provide to the Paying Agent on a timely basis, as and when
needed after the Effective Time, funds necessary to pay for the Shares as part
of the Merger pursuant to Section 2.8.

                  (c)      As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding Shares (the "Certificates") whose Shares were converted
into the right to receive the Merger Consideration pursuant to Section 2.8, (i)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon delivery
of the Certificates to the Paying Agent and shall be in a form and have such
other provisions as Parent may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for the Merger
Consideration.  Upon surrender of a Certificate for cancellation to the Paying
Agent or to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal, duly executed, and such other documents as may
reasonably be required by the Paying Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor the amount of cash into which
the Shares theretofore represented by such Certificate shall have been
converted pursuant to Section 2.8, and the Certificate so surrendered shall
forthwith be canceled.  In the event of a transfer of ownership of Shares which
is not registered in the transfer

                                       6
<PAGE>   131

records of the Company, payment may be made to a person other than the person
in whose name the Certificate so surrendered is registered, if such Certificate
shall be properly endorsed or otherwise be in proper form for transfer and the
person requesting such payment shall pay any transfer or other taxes required
by reason of the payment to a person other than the registered holder of such
Certificate or establish to the satisfaction of the Surviving Corporation that
such tax has been paid or is not applicable.  Until surrendered as contemplated
by this Section 2.9, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
amount of cash, without interest, into which the Shares theretofore represented
by such Certificate shall have been converted pursuant to Section 2.8.  No
interest will be paid or will accrue on the cash payable upon the surrender of
any Certificate.  In the event any Certificate shall have been lost, stolen or
destroyed, Parent may, in its discretion and as a condition precedent to the
payment of the Merger Consideration in respect of shares represented by such
Certificate, require the owner of such lost, stolen or destroyed Certificate to
make an affidavit of that fact containing such indemnification provisions as
Parent may deem appropriate, including, without limitation, the posting of a
bond in such amount as Parent may reasonably direct as indemnity against any
claim that may be made against it, the Surviving Corporation or the Paying
Agent with respect to such Certificate.

                  (d)      All cash paid upon the surrender of Certificates in
accordance with the terms of this Article 2 shall be deemed to have been paid
in full satisfaction of all rights pertaining to the Shares theretofore
represented by such Certificates, and there shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of the
Shares which were outstanding immediately prior to the Effective Time.  If,
after the Effective Time, Certificates are presented to the Surviving
Corporation or the Paying Agent for any reason, they shall be canceled and
exchanged as provided in this Article 2.

                  (e)      None of Parent, Merger Sub, the Company or the
Paying Agent shall be liable to any person in respect of any cash delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.  If any Certificates shall not have been surrendered prior to
seven years after the Effective Time (or immediately prior to such earlier date
on which any payment pursuant to this Article 2 would otherwise escheat to or
become the property of any federal, state or local government or any court,
administrative or regulatory agency or commission or other governmental
authority or agency, domestic or foreign (a "Governmental Entity")), the cash
payment in respect of such Certificate shall, to the extent permitted by
applicable law, become the property of the Surviving Corporation, free and
clear of all claims or interests of any person previously entitled thereto.

         2.10     Transfer of Shares After Effective Date.  No transfers of
Shares shall be made on the stock transfer books of the Surviving Corporation
at or after the Effective Time.

         2.11     Company Stock Options.  As of the Effective Time, each option
(a "Stock Option") to purchase Shares under the Company's 1989 Stock Incentive
Plan (the "1989 Plan"), 1992 Stock Incentive Plan (the "1992 Plan"), 1992
Director Incentive Plan (the "1992 Director Plan"), 1993 Stock Incentive Plan
(the "1993 Plan"), 1993 Director Incentive Plan (the "1993 Director Plan"), the
Insight Imaging Systems, Inc. 1994 Stock Option Plan (the "Insight Plan") and
the 1995 Stock

                                       7
<PAGE>   132

Incentive Plan (the "1995 Plan" and together with the 1989 Plan, the 1992 Plan,
the 1992 Director Plan, the 1993 Plan, the 1993 Director Plan and the Insight
Plan, the "Stock Option Plans," true, complete and correct copies of which have
heretofore been furnished to Parent), whether or not then exercisable in
accordance with its terms, shall be converted into the right to receive, upon
the surrender of the agreement evidencing such Stock Option to the Paying Agent
in accordance with the provisions of Section 2.9 applicable to Certificates and
upon the delivery to the Paying Agent of the "Stock Option Acknowledgment"
referred to below, an amount in cash (net of applicable withholding) equal to
the excess, if any, of the Merger Consideration over the exercise price per
Share subject to such Stock Option (each, an "Option Share") multiplied by the
number of Option Shares previously subject to such Stock Option (assuming full
vesting of all Stock Options).  Each holder of a Stock Option who surrenders
the agreement evidencing such Stock Option to the Paying Agent shall execute a
written acknowledgment, in form satisfactory to Parent (the "Stock Option
Acknowledgment"), that such holder's receipt of cash in exchange for such Stock
Option shall be in full settlement of such Stock Option and that such holder
understands that such Stock Option shall, as of the Effective Time, represent
only the right to receive cash in accordance with this Section 2.11 and shall
otherwise be canceled.  Regardless of the number of Stock Options (if any) so
surrendered, all Stock Options shall be canceled at the Effective Time and
shall thereafter represent only the right to receive the amount of cash payable
under this Section 2.11 upon compliance with the terms hereof.

         2.12     Company Warrants.  As of the Effective Time, each warrant to
purchase Shares (a "Warrant"), whether or not then exercisable in accordance
with its terms, shall be converted into the right to receive, upon the
surrender of the agreement evidencing such Warrant to the Paying Agent in
accordance with the provisions of Section 2.9 applicable to Certificates and
upon the delivery to the Paying Agent of the "Warrant Acknowledgment" referred
to below, an amount in cash (net of applicable withholding) equal to the
excess, if any, of the Merger Consideration over the exercise price per share
of the Common Stock of the Company subject to such Warrant (each, a "Warrant
Share") multiplied by the number of Warrant Shares previously subject to such
Warrant.  Each holder of a Warrant who surrenders the agreement evidencing such
Warrant to the Paying Agent shall execute a written acknowledgment, in form
satisfactory to Parent (the "Warrant Acknowledgment"), that such holder's
receipt of cash in exchange for such Warrant shall be in full settlement of
such Warrant and that such holder understands that such Warrant shall, as of
the Effective Time, represent only the right to receive cash in accordance with
this Section 2.12 and shall otherwise be canceled.  Regardless of the number of
Warrants, if any, so surrendered, all Warrants shall be canceled at the
Effective Time and shall thereafter represent only the right to receive the
amount of cash payable under this Section 2.12 upon compliance with the terms
hereof.

Neither the Company nor any Subsidiary is subject to or obligated under any
provision of (a) its respective Certificate of Incorporation or By-Laws,
(b) any contract, (c) any license, franchise or permit, or (d) any law,
regulation, order, judgment or decree, which would be breached, violated or
defaulted (with or without due notice or lapse of time or both) or in respect
of which a right of termination or acceleration or a loss of a material benefit
or any encumbrance on any of its assets would be created or suffered by its
execution and performance of this Agreement, except (as to clauses (b), (c) or
(d) above) where such breach, violation, default, right of termination or
acceleration, loss or encumbrance, individually or in the aggregate, would not
have a Material Adverse Effect on the Company.  The consummation of the Offer
and the Merger by the Company will not require the consent or approval of, or a
registration or filing with, any person or Governmental Entity, other than
(w) approval of the holders of Shares if required by applicable law or the
Company's Certificate of Incorporation or Bylaws, (x) applicable requirements,
if any, of the Exchange Act, state "blue sky" or takeover laws and the

Material Adverse Effect on the Company or prevent or materially delay the
Company from performing its obligations under this Agreement.

during each fiscal year beginning with the fiscal year 1993 and (d) all other
reports filed by the Company with the SEC since June 30, 1993 (collectively,
the "SEC Documents").  As of their respective dates, the SEC Documents complied
as to form in all material respects with the requirements of the Exchange Act
and the rules and regulations of the SEC promulgated thereunder and applicable
to such SEC Documents, and none of the SEC Documents contained any untrue
statement of a material fact or omitted to state a material fact required to be

circumstances under which they were made, not misleading, except for such

included in the SEC Documents comply with applicable accounting requirements
and the rules of the SEC with respect thereto, have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
(except as may be specifically indicated therein or in the notes thereto,
except for such statements, if any, as have been modified by subsequent filings

and its consolidated Subsidiaries as of the dates thereof and the consolidated
results of their operations, changes in stockholders' equity and statements of
cash flows (or changes in financial position prior to the approval of FASB 95)
for the periods then ended, subject, in the case of the unaudited consolidated
interim financial statements, to normal year-end adjustments and any other
adjustments described therein.

         3.7      No Undisclosed Liabilities.  Neither the Company nor any of
its Subsidiaries has any liabilities, obligations or commitments of any nature

(herein "Liabilities"), except (a) Liabilities which are adequately reflected
or reserved against in the financial statements of the Company for the quarter
ended September 30, 1996, (b) Liabilities which have been incurred in the
ordinary course of business and consistent with past practice since September
30, 1996 which individually or in the aggregate would not have a Material

         3.8      Absence of Certain Changes or Events.  Except as heretofore
disclosed in the SEC Documents, since the date of the most recently audited
financial statements included in the SEC Documents, the Company has conducted
its business only in the ordinary course, and there has not been:

                  (a)      any event, act, occurrence or omission to act or
occur having or which, insofar as reasonably can be foreseen, may have, a
Material Adverse Effect on the Company;

                  (b)      any declaration, setting aside or payment of any
dividend or other distribution (whether in cash, stock or property) with

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

                  (d)      (i) any granting by the Company or any of its
Subsidiaries to any executive officer of the Company or any of its Subsidiaries
of any increase in compensation, except as required under employment agreements
in effect as of the date of the most recent audited financial statements
included in the SEC Documents, (ii) any granting by the Company or any of its
Subsidiaries to any such executive officer of any increase in severance or
termination pay, except as required under any employment, severance or
termination agreement in effect as of the date of the most recent audited
financial statements included in the SEC Documents (true, complete and correct
copies of all of which agreements have heretofore been furnished to Parent),
(iii) any entry by the Company or any of its Subsidiaries into any employment,
severance or termination agreement with any such executive officer, or (iv) any

included within subsections (d) and (e) of Section 3.4);

                  (e)      any damage, destruction or loss, whether or not
covered by insurance, that has or could, insofar as reasonably can be foreseen,
have, a Material Adverse Effect on the Company; or

the Company.

         3.9      Litigation.  Except as disclosed in the SEC Documents, as of
the date of this Agreement, there is no suit, action or proceeding pending or,
to the knowledge of the Company, threatened against the Company or any of its
Subsidiaries that individually or in the aggregate could reasonably be expected
to (a) have a Material Adverse Effect on the Company, (b) materially impair the
ability of the Company to perform its obligations under this Agreement or (c)
prevent the consummation of any of the transactions contemplated by this
Agreement, nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against the Company or any of its
Subsidiaries having, or which is reasonably likely to have, any effect referred
to in the foregoing clauses (a), (b) or (c) above.

         3.10     Absence of Changes in Benefit Plans.  Except as disclosed in
the SEC Documents, since the date of the most recent audited financial
statements included in the SEC Documents, there has not been any adoption or
amendment in any material respect by the Company or any of its Subsidiaries of
any bonus, pension, profit sharing, deferred compensation, incentive
compensation, stock ownership, stock purchase, stock option, phantom stock,
retirement, vacation, severance, disability, death benefit, hospitalization,
medical or other plan, arrangement or understanding (whether or not legally
binding) providing benefits to any current or former employee, officer or
director of the Company or any of its Subsidiaries; true, complete and correct
copies of all of such plans, arrangements and understandings have heretofore
been furnished to Parent.  Except as disclosed in the SEC Documents, there are
no employment, consulting, severance, termination or indemnification
agreements, arrangements or understandings in effect (other than employment and
consulting agreements which are terminable at will without liability to the
Company) between the Company or any of its Subsidiaries and any current or
former employee, officer or director of the Company or any of its Subsidiaries.

         3.11     ERISA Compliance.

                  (a)      The Company Disclosure Schedule contains a list  of
each "employee pension benefit plan" (as defined in Section 3(2) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
(sometimes referred to herein as a "Pension Plan"), each "employee welfare
benefit plan" (as defined in Section 3(1) of ERISA) and each stock option,
stock purchase, deferred compensation plan or arrangement and each other
employee fringe benefit plan (as defined in Section 6039D(d) of the Internal
Revenue Code of 1986, as amended (the "Code")) maintained, contributed to or
required to be maintained or contributed to by the Company, any of its
Subsidiaries or any other person or entity that, together with the Company, is
treated as a single employer under Section 414(b), (c), (m) or (o) of the Code,
(each, a "Commonly Controlled Entity"), for the benefit of any

                                       13
<PAGE>   138

current or former employees, officers, directors or independent contractors of
the Company or any of its Subsidiaries (collectively, "Benefit Plans").  The
Company has delivered to Parent true, complete and correct copies of (i) each
Benefit Plan (or, in the case of any unwritten Benefit Plans, descriptions
thereof), (ii) the most recent annual report on Form 5500 filed with the
Internal Revenue Service with respect to each Benefit Plan (if any such report
was required), (iii) the most recent summary plan description for each Benefit
Plan for which such summary plan description is required and (iv) each
currently effective trust agreement and insurance or group annuity contract
relating to any Benefit Plan.

                  (b)      To the knowledge of the Company, there has been no
failure to administer any Benefit Plan in all material respects in accordance
with its terms, and no failure of the Company, its Subsidiaries or any Benefit
Plan to comply in all material respects with ERISA or the Code.

                  (c)      All Pension Plans intended to be qualified under
Section 401(a) of the Code have been the subject of determination letters from
the Internal Revenue Service to the effect that such Pension Plans are
qualified and exempt from federal income taxes under Sections 401(a) and
501(a), respectively, of the Code and no such determination letter has been
revoked nor, to the knowledge of the Company, has revocation been threatened,
nor has any such Pension Plan been amended since the date of its most recent
determination letter or application therefor in any respect that would
adversely affect its qualification or materially increase its costs.

                  (d)      No Pension Plan that the Company or any of its
Subsidiaries maintains, or to which the Company or any of its Subsidiaries is
obligated to contribute, other than any Pension Plan that is a "multiemployer
plan" (as such term is defined in Section 4001(a)(3) of ERISA; collectively,
the "Multiemployer Pension Plans"), had, as of the respective last annual
valuation date for each such Pension Plan, an "unfunded benefit liability" (as
such term is defined in Section 4001(a)(18) of ERISA), based on actuarial
assumptions which have been furnished to Parent, and neither the Company nor
any of its Subsidiaries is aware of any facts or circumstances that would
materially change the funded status of any such Benefit Plans.  None of the
Pension Plans has an "accumulated funding deficiency" (as such term is defined
in Section 302 of ERISA or Section 412 of the Code), and there has been no
application for a waiver of the minimum funding standards imposed by Section
412 of the Code with respect to any Benefit Plan that is a Pension Plan.

                  (e)      None of the Company, any of its Subsidiaries, any
officer of the Company or any of its Subsidiaries or any of the Benefit Plans
which are subject to ERISA, including the Pension Plans, any trusts created
thereunder or any trustee or administrator thereof, has engaged in a nonexempt
"prohibited transaction" (as such term is defined in Section 406 of ERISA or
Section 4975 of the Code) or any other breach of fiduciary responsibility that
could subject the Company, any of its Subsidiaries or any officer of the
Company or any of its Subsidiaries to tax or penalty under ERISA, the Code or
other applicable law that has not been corrected or that individually or in the
aggregate would have a Material Adverse Effect on the Company (determined
assuming that the tax under Section 4975(b) of the Code is imposed with respect
to such prohibited transaction).   Any taxes or penalties arising from
prohibited transactions referred to in this Section 3.11(e) that have been
corrected have been paid in full.  Neither any of such Benefit Plans nor any of
such trusts that

                                       14
<PAGE>   139

are subject to Title IV of ERISA has been terminated, nor has there been any
"reportable event" (as that term is defined in Section 4043 of ERISA) with
respect thereto, during the last three years.

                  (f)      Neither the Company nor any Commonly Controlled
Entity has suffered or otherwise caused a "complete withdrawal" or a "partial
withdrawal" (as such terms are defined in Section 4203 and Section 4205,
respectively, of ERISA) with respect to any of the Multiemployer Pension Plans
that could lead to the imposition of any withdrawal liability under Section
4201 of ERISA; and no action has been taken that alone or with the passage of
time could result in either a partial or complete withdrawal by any Commonly
Controlled Entity in respect of any such plan.

                  (g)      With respect to any Benefit Plan that is an employee
welfare benefit plan, (i) no such Benefit Plan is funded through a "welfare
benefit fund," as such term is defined in Section 419(e) of the Code, (ii) each
such Benefit Plan that is a "group health plan," as such term is defined in
Section 5000(b)(1) of the Code, complies in all material respects with the
applicable requirements of Section 4980B(f) of the Code and (iii) each such
Benefit Plan (including any such Plan covering retirees or other former
employees) may be amended or terminated without material liability to the
Company or any of its Subsidiaries on or at any time after the consummation of
the Offer, after giving any notice required by ERISA or the Code.

                  (h)      No Commonly Controlled Entity has incurred any
material liability to a Pension Plan (other than for contributions not yet
due).

         3.12     Taxes.

                  (a)      Each of the Company and each of its Subsidiaries has
filed all material tax returns and reports required to be filed by it
("Returns").  All such Returns are complete and correct in all material
respects.  Each of the Company and each of its Subsidiaries has paid (or the
Company has paid on its behalf or made provision for) all material taxes
required to be paid by it, and the most recent financial statements contained
in the SEC Documents properly reflect in accordance with generally accepted
accounting principles all material taxes payable by the Company and its
Subsidiaries for all taxable periods and portions thereof through the date of
such financial statements.

                  (b)      No material deficiencies for any taxes have been
proposed, asserted or assessed against the Company or any of its Subsidiaries
that have not been fully paid or are not properly reflected in accordance with
generally accepted accounting principles in the most recent financial
statements contained in the SEC Documents, other than those taxes being
contested in good faith, and no requests for waivers of the time to assess any
such taxes are pending.  The Company has not agreed with any tax authority to
extend the time to assess any such taxes.  The Company has not entered into any
closing agreement with respect to any taxable year.

                  (c)      The Company Disclosure Schedule sets forth (i) the
taxable years of the Company or any of its Subsidiaries as to which the
respective statutes of limitations with respect to federal income taxes have
not yet expired, and (ii) those taxable years and taxes as to which the Company
has agreed to extend the applicable statute of limitations.

                                       15
<PAGE>   140

                  (d)      None of the Company or any of its Subsidiaries has,
and none of them has ever had, a permanent establishment in any non-U.S.
country, as defined in any applicable tax treaty or convention between the
United States and such non-U.S. country, or any presence in a non-U.S.  country
with which the United States does not have a tax treaty or convention that
could subject the Company or any Subsidiary to the tax laws of such non-U.S.
country.

                  (e)      As used in this Agreement, "taxes" shall include all
federal, state, local and foreign income, property, sales, excise and other
taxes, tariffs or duties of any nature whatsoever.

                  (f)      The Company is not a party to any agreements that
could reasonably be expected to result in any payments that would be
characterized as "excess parachute payments" (as such term is defined in
Section 280G(b)(1) of the Code.

         3.13     Information Supplied.  None of the information supplied or to
be supplied by the Company in writing specifically for inclusion in, and none
of the information specifically to be incorporated by reference in, (a) the
Offer Documents, (b) the Schedule 14D-9, (c) the information statement to be
filed by the Company in connection with the Offer pursuant to Rule 14f-1
promulgated under the Exchange Act (the "Information Statement"), if any, or
(d) any proxy statement (the "Proxy Statement") relating to the "Stockholders
Meeting" (as defined in Section 6.1(a)), will, in the case of the Offer
Documents, the Schedule 14D-9 and the Information Statement, at the respective
times that the Offer Documents, the Schedule 14D-9 and the Information

Company's stockholders, or, in the case of the Proxy Statement, at the time the
Proxy Statement is first mailed to the Company's stockholders or at the time of
the Stockholders Meeting, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading.  The Schedule 14D- 9, the Information Statement
and the Proxy Statement will comply in all material respects with the
requirements of the Exchange Act and the rules and regulations thereunder,
except that no representation or warranty is made by the Company with respect
to statements made or incorporated by reference therein based on information
supplied in writing by Parent or Merger Sub specifically for inclusion or
incorporation by reference therein.

         3.14     Compliance with Applicable Laws.

                  (a)      Each of the Company and each of its Subsidiaries has
in effect all material federal, state, local and foreign governmental
approvals, authorizations, certificates, filings, franchises, licenses,
notices, permits and rights ("Permits") necessary for it to own, lease or
operate its properties and assets and to carry on its business as now
conducted, and there has occurred no default under any such Permit, except for
the lack of Permits and for defaults under Permits which lack or default
individually or in the aggregate would not have a Material Adverse Effect on
the Company.

                  (b)      Except as disclosed in the SEC Documents, to the
knowledge of the Company, the businesses of the Company and its Subsidiaries
are not being conducted in violation of any law,

                                       16
<PAGE>   141

ordinance or regulation of any Governmental Entity, except for violations that
would not have a Material Adverse Effect on the Company.  As of the date of
this Agreement, no investigation or review by any Governmental Entity with
respect to the Company or any of its Subsidiaries is pending or, to Company's
knowledge, threatened, nor has any Governmental Entity communicated to the
Company an intention to conduct any such investigation or review.

                  (c)      Except as disclosed in the SEC Documents, each of
the Company and its Subsidiaries is, and has been, and each of the Company's
former Subsidiaries, while Subsidiaries of the Company, was, in material
compliance with all applicable "Environmental Laws" (as defined below), except
for noncompliance that would not have a Material Adverse Effect on the
Company).  The term "Environmental Laws" means any federal, state or local
statute, code, ordinance, rule, regulation, policy, guideline, permit, consent,
approval, license, judgment, order, writ, decree, directive or injunction now
in effect, including the requirement to register underground storage tanks,
relating to:  (i) "Releases" (as defined below) or threatened Releases of
"Hazardous Material" (as defined below) into the environment, including into
ambient air, soil, sediments, land surface or subsurface, buildings or
facilities, surface water, groundwater, publicly-owned treatment works, septic
systems or land; or (ii) the generation, treatment, storage, disposal, use,
handling, manufacturing, transportation or shipment of Hazardous Material.

                  (d)      During the period of ownership or operation by the
Company and its current and former Subsidiaries of any of their respective
current or previously owned or leased properties, the Company has no knowledge
of any Releases of Hazardous Material in, on, under or affecting such properties
that would trigger reporting or cleanup obligations on the part of the Company
or its Subsidiaries under applicable environmental laws, and none of the Company
or its current and former Subsidiaries has disposed of any Hazardous Material or
any other substance in a manner that could reasonably be anticipated to lead to
a Release in, on or affecting such properties.  To the Company's knowledge,
prior to the period of ownership or operation by the Company and its current and
former Subsidiaries of any of their respective current or previously owned or
leased properties,  no Hazardous Material was generated, treated, stored,
disposed of, used, handled or manufactured at, or transported, shipped or
disposed of from, such current or previously owned properties, and the Company
has no knowledge of any Releases of Hazardous Material in, on, under or
affecting any such property that would trigger reporting or cleanup obligations
on the part of the Company or its Subsidiaries under applicable environmental
laws.  The term "Release" has the meaning set forth in 42 U.S.C. Section
9601(22).  The term "Hazardous Material" means (i) hazardous materials,
pollutants, contaminants, constituents, medical or infectious wastes, hazardous
wastes and hazardous substances as those terms are defined in the following
statutes and their implementing regulations:  the Hazardous Materials
Transportation Act, 49 U.S.C. Section 1801 et seq., the Resource Conservation
and Recovery Act, 42 U.S.C. Section 6901 et seq., the Comprehensive
Environmental Response, Compensation and Liability Act, as amended by the

         3.15     State Takeover Statutes.  The Board of Directors of the
Company has approved the Offer, the Merger,  this Agreement  and the
Stockholder Agreements, and such approval is sufficient to render inapplicable
to the Offer, the Merger, this Agreement and the Stockholder Agreements and the
transactions contemplated by this Agreement and the Stockholder Agreements the
provisions of Section 203 of the DGCL.  No other state takeover statute or
similar statute or regulation applies or purports to apply to the Offer, the
Merger, this Agreement, the Stockholder Agreements or any of the transactions
contemplated by this Agreement or the Stockholder Agreements.

         3.16     Brokers; Schedule of Fees and Expenses.  No broker,

has been delivered to Parent, is entitled to any broker's, finder's, financial
advisor's or other similar fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of the Company.  A good faith estimate of the fees and expenses
incurred and to be incurred by the Company in connection with this Agreement
and the transactions contemplated by this Agreement (including the fees of the
Company's legal counsel) is set forth in the Company Disclosure Schedule.  No
valid claim exists against the Company or the Surviving Corporation or, based
on any action by the Company or any Subsidiary, against Parent or Merger Sub
for payment of any "topping," "break-up" or "bust-up" fee or any similar
compensation or payment arrangement as a result of the transactions
contemplated hereby, including the Offer and the Merger.

         3.17     Contracts; Debt Instruments.

                  (a)      Except as disclosed in the SEC Documents, there is
no contract or agreement, written or oral  that is material to the business,
condition (financial or otherwise), properties, assets, results of operations
of the Company or its Subsidiaries (a "Material Contract"); true, complete and
correct copies of all such Material Contracts, or written summaries of oral
agreements, have heretofore been furnished to Parent.  For the purposes hereof,
"Material Contracts" shall mean (i) all contracts that are considered to be
"material" within the meaning of Item 601(b)(10) of Regulation S-K promulgated
under the Securities Act of 1933, as amended, and the Exchange Act and (ii) all
other agreements (whether or not material within the meaning of Regulation S-K)
that (A) limit the ability of the Company to engage or compete in any business,

employment of any individual by the Company or any of its Subsidiaries, (D)
provide for the distribution of the Company's products, (E) provide for the
license by or from the Company of any patents, copyrights, trademarks or other

litigation.  All such Material Contracts are in full force and effect, and, to
the Company's knowledge, the parties thereto other than the Company and its
Subsidiaries have complied and are complying with all of their obligations and
are not in default under (nor, to the Company's knowledge, does there exist any
condition which upon the passage of time or the giving of notice would
reasonably be expected to cause such a violation of or default under) any of
such Material Contracts.  Neither the Company nor any of its Subsidiaries is in
violation of or in default under (nor

                                       18
<PAGE>   143

does there exist any condition which upon the passage of time or the giving of
notice would reasonably be expected to cause such a violation of or default
under) any loan or credit agreement, note, bond, mortgage, indenture, lease,
permit, concession, franchise, license or any other contract, agreement,
arrangement or understanding to which it is a party or by which it or any of
its properties or assets is bound, except where such violation or default would
not have a Material Adverse Effect on the Company.

                  (b)      Set forth on the Company Disclosure Schedule is (i)
a list of all loan or credit agreements, notes, bonds, mortgages, indentures
and other agreements and instruments (other than accounts payable) pursuant to
which any indebtedness of the Company or any of its Subsidiaries is outstanding
or may be incurred and (ii) the respective principal amounts currently
outstanding thereunder.  For purposes of this Agreement, "indebtedness" shall
mean, with respect to any person, without duplication, (A) all obligations of
such person for borrowed money, or with respect to deposits or advances of any
kind to such person, (B) all obligations of such person evidenced by bonds,
debentures, notes or similar instruments, (C) all obligations of such person
upon which interest charges are customarily paid, (D) all obligations of such
person under conditional sale or other title retention agreements relating to
property purchased by such person, (E) all obligations of such person issued or
assumed as the deferred purchase price of property or services (excluding
obligations of such person to creditors for raw materials, inventory, services
and supplies incurred in the ordinary course of such person's business), (F)
all capitalized lease obligations of such person, (G) all obligations of others
secured by any lien on property or assets owned or acquired by such person,
whether or not the obligations secured thereby have been assumed, (H) all
obligations of such person under interest rate or currency hedging transactions
(valued at the termination value thereof), (I) all letters of credit issued for
the account of such person and (J) all guarantees and arrangements having the
economic effect of a guarantee of such person of any indebtedness of any other
person.

         3.18     Title to Properties.

                  (a)      Each of the Company and each of its Subsidiaries has
good and marketable title to, or valid leasehold interests in, all its
properties and assets, free and clear of all Liens, other than (i)
materialmen's, mechanics', carriers', workers', repairmen's and other similar
Liens arising or incurred in the ordinary course of business, or statutory
landlords' Liens under leases to which the Company is a party, with respect to
which the underlying obligation is not in default, (ii) the statutory rights of
third parties with respect to inventory or work in progress under orders or
contracts entered into by the Company in the ordinary course of business, (iii)
Liens that are immaterial in amount and do not materially impair  the present
or contemplated use of the properties or assets subject thereto or affected
thereby, or otherwise materially impair present or contemplated business

<PAGE>   144

Company and its Subsidiaries have complied and are complying with all of their
obligations and are not in default under (nor does there exist any condition
which upon the passage of time or the giving of notice would reasonably be
expected to cause such a violation of or default under) any of such leases.
Each of the Company and each of its Subsidiaries enjoys peaceful and
undisturbed possession under all such leases.

         3.19     Labor Matters.  There are no collective bargaining or other
labor union agreements to which the Company or any of its Subsidiaries is a
party or by which any of them is bound.  Neither the Company nor any of its
Subsidiaries has encountered any labor union organizing activity, or had any
actual or, to the Company's knowledge,  threatened employee strikes, work
stoppages, slowdowns or lockouts.

         3.20     Insurance.  As of the date hereof, the Company and each of
its Subsidiaries are covered under insurance policies and programs which
provide coverage to the Company against such losses and risks and in such
amounts as are adequate and customary in the businesses in which they are
engaged; true, complete and correct copies of all such policies and programs
have heretofore been furnished to Parent.  All material policies of insurance
and fidelity or surety bonds insuring the Company or any of its Subsidiaries or
their respective businesses, assets, employees, officers and directors are in
full force and effect.  Except as otherwise disclosed pursuant to Section 3.9,
as of the date hereof, there are no material claims by the Company or any
Subsidiary under any such policy or instrument as to which any insurance
company is denying liability or defending under a reservation of rights clause.
All necessary notifications of claims have been made to insurance carriers.

         3.21     Intellectual Property Matters.

                  (a)      The Company owns or has the right to use, free and
clear of all Liens, charges, claims and restrictions, all know-how, processes,
patents, trade secrets, trademarks, service marks, trade names, copyrights,
licenses, proprietary rights and other intellectual property rights materially
necessary to its business as now conducted or contemplated (the "Company
Intellectual Property Rights"). Any license agreement by which any Company
Intellectual Property Right is licensed by the Company from a third party has
heretofore been furnished to Parent.

                  (b)      To the Company's knowledge it is not infringing upon
or otherwise acting adversely to any actual or claimed know-how, process,
patent, trade secret, trademark, service mark, trade name, copyright, license,
information, proprietary right or other right of any person.  The Company has
not received any communications alleging that the Company has violated or, by
conducting its business as now conducted or currently proposed to be conducted
by the Company, would violate any know-how, process, patent, trade secret,
trademark, service mark, trade name, copyright, license,  or other proprietary
right of any person, and, to the Company's knowledge, there is no basis for any
such allegation.

                  (c)      To the Company's knowledge, there is no actual or
threatened infringement or adverse use of the Company's Intellectual Property
Rights.  There are no outstanding options, licenses or agreements of any kind
relating to any Company Intellectual Property Rights in favor of

                                       20
<PAGE>   145

any third party (other than license agreements on the Company's standard form
entered into in the ordinary course of business).

                  (d)      To the Company's knowledge, neither the execution
nor delivery of this Agreement, nor the carrying on of the Company's business
by the employees of the Company, nor the conduct of the Company's business as
now conducted or under development, will conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under or a
violation of, any fiduciary duty or any contract, covenant or instrument under
which any of such employees is now obligated.  To the Company's knowledge, it
is not, nor will it be necessary to, utilize any inventions of any of the
Company's employees made prior to their employment by the Company.

                  (e)      No present or former employee of the Company or its
Subsidiaries and no other person owns or has any proprietary, financial or
other interest, direct or indirect, in whole or in part, in any Company
Intellectual Property Rights.  The Company Disclosure Schedule lists all
confidentiality or non-disclosure agreements to which the Company or its
Subsidiaries or any of its or their employees is a party, other than customary
agreements on the Company's standard form with employees who are not officers
or directors.

         3.22     Payments.  Neither the Company nor any of its Subsidiaries
has paid or delivered any fee, commission or other sum of money or item of
property to any finder, agent, government official or other party, in the
United States or any other country, which is related to the business or
operations of the Company or any of its Subsidiaries, which the Company knows
or has reason to believe to have been illegal under any federal, state or local
laws of the United States or any other country having jurisdiction; and to the
Company's knowledge, neither the Company nor any of its Subsidiaries has
participated in any illegal boycotts or other similar practices affecting any
of its actual or potential customers.  To the Company's knowledge, the Company
and its Subsidiaries are in compliance in all material respects with the
Foreign Corrupt Practices Act.

         3.23     Suppliers and Customers.  There are no material agreements
which commit the Company or any of its Subsidiaries to sell products or
purchase materials or components at fixed prices or prices determined by an
established formula, other than purchase orders on the Company's standard form
for normal commercial quantities entered into in the ordinary course.  Except
as disclosed in the SEC Documents, no customer accounted for more than five
percent of the Company's or any of its Subsidiaries sales in either of the past
two fiscal years (any such customer being a "Material Customer") and no
supplier material to the business of the Company and its Subsidiaries, taken as
a whole, or Material Customer has terminated its relationship with the Company
or any of its Subsidiaries or has during the past fiscal year materially
decreased or delayed, or, to the Company's knowledge, threatened to materially
decrease or delay its services or supplies to the Company or any of its
Subsidiaries or decrease its usage of the Company's or any of its Subsidiaries'
products or services.  None of the Company or any of its Subsidiaries is aware
of any facts or events which may reasonably be expected to form the basis for
such a decrease or delay. Set forth on the Company Disclosure Schedule is a
complete and accurate list of:


                                       21

the six months ended December 31, 1996;

                  (b)      each customer to whom sales exceeded $42,000 for the
six months ended December 31, 1996 and the aggregate sales with respect to each
such customer; and

                  (c)      each supplier who constitutes a single source of
supply to the Company or any of its Subsidiaries where purchases exceeded
$25,000 for the last fiscal year.

         3.24     Regulatory Matters.

                  (a)      None of the Company or any of its Subsidiaries sells
any products for which a premarket approval of or 510(k) notification to the
U.S. Food and Drug Administration ("FDA") or any other federal, state, local,
non-U.S. or other governmental authority is required, or for which applications
for premarket approval or premarket notification have been filed or granted,
and there are no products sold by the Company or any of its Subsidiaries which
are, and none of the Company or any of its Subsidiaries is, otherwise subject
to the jurisdiction of the FDA or any similar state, local, non-U.S. or other
governmental authority.

                  (b)      To the Company's knowledge, there exists no set of
facts which would cause the Company or any of its Subsidiaries to recall any
product from the market or to restrict the marketing of any product or to
terminate or suspend testing of any product.

authorized by the respective Boards of Directors of Parent and Merger Sub and
by Parent as the sole stockholder of Merger Sub, and no other corporate

which would be breached, or violated or defaulted (with or without due notice
or lapse of time or both) or in respect of which a right of termination or
acceleration or a loss of a material benefit or any encumbrance on any of its
assets would be created by its execution and performance of this Agreement,
except (as to (b), (c) or (d) above) where such breach, violation or right
would not, individually or in the aggregate have a Material Adverse Effect on
Parent or  prevent or materially delay Parent or Merger Sub from performing its
obligations under this Agreement.  The consummation of the Offer and the Merger
by Parent and Merger Sub will not require the consent or approval of any party
other than (x) applicable requirements, if any, of the Exchange Act, state
"blue sky" or takeover laws and the HSR Act, (y) filing and recordation of
appropriate merger documents as required by the DGCL and (z) where failure to

have a Material Adverse Effect on Parent or prevent or materially delay Parent
or Merger Sub from performing its obligations under this Agreement.

         4.3      Financing.  Parent has, or has the borrowing facilities to
obtain, all funds necessary for the payment of the aggregate purchase price of

any Shares by virtue of the execution of the Stockholder Agreements).

         4.5      Information Supplied.  None of the information supplied or to
be supplied by Parent or Merger Sub specifically for inclusion in, and none of

case of the Proxy Statement, at the time the Proxy Statement is first mailed to
the Company's stockholders or at the time of the Stockholders Meeting, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.

consists of 1,000 shares of common stock.  As of the date hereof, there are 100
shares of common stock of Merger Sub outstanding.  All outstanding shares of

advisory services to, and has not been paid

                                       23

subsidiaries or affiliates; provided, however, Cleary Gull may have,  since
January 1, 1995, made a market in and traded, and may in the future make a
market in and trade, securities of Parent in the ordinary course of its
business for its own account and the account of its customers.  This
representation and warranty is intended to benefit the Company and each member

                       ARTICLE 6 -- ADDITIONAL AGREEMENTS

         6.1      Stockholder Approval; Preparation of Proxy Statement.

                  (a)  If the approval of the Merger by the Company's
Stockholders (the "Company Stockholder Approval") is required by law, the
Company will, at Parent's request, as soon as practicable in accordance with
applicable law following acceptance for payment of and payment for shares of
Company Common Stock, duly call, give notice of, convene and hold a meeting of
its stockholders (the "Stockholders' Meeting") for the purpose of obtaining
such Company Stockholder Approval.  The Company will, through its Board of
Directors, subject to Section 6.5(b) hereof, recommend to its stockholders that
such Company Stockholder Approval be given.  Notwithstanding the foregoing, if
Parent, Merger Sub or any other subsidiary of Parent shall acquire at least 90%
of

                                       26
<PAGE>   151

the outstanding Shares, the parties shall, at the request of Parent, take all
necessary and appropriate action to cause the Merger to become effective as
soon as practicable after the expiration of the Offer without a Stockholders'
Meeting in accordance with Section 253 of the DGCL.  Without limiting the
generality of the foregoing, the Company agrees that its obligations pursuant
to the first sentence of this Section 6.1(a) shall not be affected by (i) the
commencement, public proposal, public disclosure or communication to the
Company of any "Acquisition Proposal" (as defined in Section 6.5(a)) that is
not a "Superior Acquisition Proposal" (as defined in Section 6.5(b)) or (ii)
the withdrawal or modification by the Board of Directors of the Company of its
approval or recommendation of the Offer, this Agreement or the Merger.

                  (b)  If the Company Stockholder Approval is required by law,
the Company will, at Parent's request, as soon as practicable following
acceptance for payment of and payment for shares of Company Common Stock,
prepare and file a preliminary Proxy Statement (or, if applicable, an
information statement in lieu of proxy statement pursuant to Rule 14C under the
Exchange Act, with all references herein to the Proxy Statement being deemed to
refer to such information statement, to the extent applicable) with the SEC and
will use its best efforts to respond to any comments of the SEC or its staff
and to cause the definitive Proxy Statement to be mailed to the Company's
stockholders as promptly as practicable after responding to all such comments
to the satisfaction of the SEC staff.  The Company will notify Parent promptly
of the receipt of any comments from the SEC or its staff and of any request by
the SEC or its staff for amendments or supplements to the Proxy Statement or
for additional information and will supply Parent with true, complete and
correct copies of all correspondence between the Company or any of its
representatives, on the one hand, and the SEC or its staff, on the other hand,
with respect to the Proxy Statement or the Merger.  If at any time prior to the
Stockholders' Meeting there shall occur any event that should be set forth in
an amendment or supplement to the Proxy Statement, the Company will promptly
prepare and mail to its stockholders such an amendment or supplement.  The
Company will not mail any Proxy Statement, or any amendment or supplement
thereto, to which Parent reasonably objects, it being understood that Parent
may not reasonably object to the inclusion of information deemed necessary by
the Company, upon the written advice of its outside counsel, in order to comply
with the Exchange Act and the rules and regulations promulgated thereunder.

                  (c)  Parent agrees to cause all Shares purchased pursuant to
the Offer and all other Shares owned by Merger Sub or any other subsidiary of
Parent to be voted in favor of the Company Stockholder Approval.

         6.2      Stock Options and Warrants .  Within five business days after
the commencement of the Offer, the Company will notify in writing each holder
of a Stock Option under the Stock Option Plans and each  holder of a Warrant of
the effect of the Merger on the rights of the option holder and warrant holder
as described in Section 2.11 and Section 2.12, respectively.

         6.3      Expenses.

                  (a) Except as provided in Section 6.3(b) below, whether or
not the Offer and/or the Merger are consummated, each of the Company and Parent
will separately bear its own expenses,

                                       27
<PAGE>   152

including the fees and disbursements of counsel, investment bankers and
accountants, incurred in connection with the Offer, the Merger, this Agreement
and the transactions contemplated hereby.

                  (b)      If the Company or any Affiliate or Agent (as defined
in Section 6.5) of the Company shall fail to fulfill its obligations under
Section 6.5, or shall enter into an agreement which contemplates the sale of
all or any material portion of the assets of, or any equity interest in, the
Company to a third party, or the parties to the Stockholder Agreements or any
of them shall enter into an agreement which contemplates such a transaction,
then, in any such case, the Company shall promptly reimburse Parent for all of
its out-of-pocket expenses incurred in connection with the Offer, the Merger,
this Agreement, the Stockholder Agreements or any transactions contemplated by
this Agreement or the Stockholder Agreements.

         6.4      Other Actions.  Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use all reasonable efforts to
take, or cause to be taken, all action and to do, or cause to be done, all

promptly as practicable the transactions contemplated by the Offer and this
Agreement, including (a) consummation of the Offer and payment for the Shares
duly and properly tendered therein, (b) filing the Certificate of Merger
referred to in Section 2.2, (c) removing any legal impediment to the

Act and submissions of information requested by governmental authorities,
subject to the appropriate vote of stockholders of the Company required to so
vote as described in Section 6.1(a).

         6.5      Exclusive Dealing.

                  (a)      Neither the Company nor any of its Subsidiaries,
officers, directors, or the directors and officers of its Subsidiaries, nor any
of its other affiliates (each, an "Affiliate") shall, and the Company shall
cause its and its respective Affiliates' employees, agents and representatives
(including, without limitation, any investment banking, legal or accounting
firm retained by the Company or any of its Affiliates and any individual member
or employee of the foregoing) (each, an "Agent") not to:  (i) initiate, solicit
or seek, directly or indirectly, any inquiries or the making or implementation
of any proposal or offer (including, without limitation, any proposal or offer
to its stockholders or any of them) with respect to a merger, acquisition,
consolidation, recapitalization, liquidation, dissolution or similar
transaction involving, or any purchase of all or a substantial portion of the
assets or any equity securities of, the Company or any of its Subsidiaries,
except for the transactions contemplated by this Agreement (any such proposal
or offer being hereinafter referred to as an "Acquisition Proposal"); or (ii)
engage in any negotiations concerning, or provide any confidential information
or data to, or have any discussions with, any person relating to an Acquisition
Proposal; or (iii) otherwise cooperate in any effort or attempt to make,
implement or accept an Acquisition Proposal; provided, however, that the
Company may, if it receives an Acquisition Proposal which was not directly or
indirectly initiated, solicited or otherwise sought by the Company or by any of
its Affiliates or its or their respective Agents, and which is a Superior
Acquisition Proposal (as defined below), respond to such Superior Acquisition
Proposal by engaging

                                       28
<PAGE>   153

in negotiations with respect thereto and providing nonpublic information
concerning the Company to the person making such Superior Acquisition Proposal,
provided that such person has entered into a written confidentiality agreement
on terms no more favorable to such person than the Mutual Confidential
Non-Disclosure Agreement, dated October 8, 1996, between the Company and
Parent, is to Parent, and provided further that the Company has received a
written opinion of its outside counsel that such response is required in order
to satisfy the fiduciary duties imposed under applicable law on its Board of
Directors.  The Company shall take the necessary steps to inform the
individuals and entities referred to in the first sentence hereof of the
obligations undertaken in this Section 6.5(a).

                  (b)      Unless this Agreement has theretofore been
terminated pursuant to Section 8.1(f) hereof, neither the Board of Directors of
the Company nor any committee thereof shall (i) withdraw or modify, or propose
to withdraw or modify, in a manner adverse to Parent or Merger Sub, the
approval or recommendation by such Board of Directors or any such committee of
the Offer, this Agreement or the Merger, (ii) approve or recommend, or propose
to approve or recommend, any Acquisition Proposal, or (iii) enter into any
agreement with respect to any Acquisition Proposal.  Notwithstanding the
foregoing, in the event the Board of Directors of the Company receives an
Acquisition Proposal that constitutes a "Superior Acquisition Proposal" (as
defined below), the Board of Directors may (subject to the limitations
contained in this Section) withdraw or modify its approval or recommendation of
the Offer, this Agreement or the Merger, approve or recommend any such Superior
Acquisition Proposal, enter into an agreement with respect to any such Superior
Acquisition Proposal or terminate this Agreement, in each case at any time
after 48 hours following Parent's receipt of written notice (a "Notice of
Superior Acquisition Proposal") advising Parent that the Board of Directors has
received a Superior Acquisition Proposal, specifying the material terms and
conditions of such Superior Acquisition Proposal and identifying the person
making such Superior Acquisition Proposal. For purposes of this Agreement, a
"Superior Acquisition Proposal" means an Acquisition Proposal received by the
Company without violation of the provisions of Section 6.5(a), having terms
which the Board of Directors of the Company determines, in the exercise of its
fiduciary duties, after consultation with outside counsel, and upon the written
opinion of its outside financial advisor to be more favorable to the Company's
stockholders from a financial point of view than the Offer and the Merger.

                  (c)      In addition to the obligations of the Company set
forth in paragraph (b) of this Section 6.5, the Company shall promptly advise
Parent orally and in writing of any request for nonpublic information relating
to the Company or by any person that, to the Company's knowledge, may be
considering making, or has made, an Acquisition Proposal, or the receipt of any
Acquisition Proposal, or any inquiry with respect to any Acquisition Proposal,
the material terms and conditions of such request, Acquisition Proposal or
inquiry, and the identity of the person making any such Acquisition Proposal or
inquiry.  The Company will keep Parent fully informed of the status and details
of any such request, Acquisition Proposal or inquiry.

         6.6      Notification of Certain Matters.  The Company shall give
prompt notice to Parent, and Parent shall give prompt notice to the Company, of
(a) 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 hereof

                                       29
<PAGE>   154

to the Effective Time, and (b) any material failure of the Company or Parent,
as the case may be, or 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 hereunder.

         6.7      Access to Information.  The Company shall, and shall cause
its Subsidiaries, officers, directors, employees and agents to, upon reasonable
notice, afford the officers, employees, agents and representatives of Parent
complete access at all reasonable times, from the date hereof to the Effective
Time, to its officers, employees, agents, properties, books and records, and
shall furnish Parent all financial, operating and other data and information as
Parent, through its officers, employees, agents or representatives, may
reasonably request.

         6.8      Antitrust Laws.  As promptly as practicable, the Company,
Parent and Merger Sub shall make all filings and submissions under the HSR Act
as may be reasonably required to be made in connection with this Agreement and
the transactions contemplated hereby.  Subject to Section 6.7 hereof, the
Company will furnish to Parent and Merger Sub, and Parent and Merger Sub will
furnish to the Company, such information and assistance as the other may
reasonably request in connection with the preparation of any such filings or
submissions.  Subject to Section 6.7 hereof and to the preservation of
attorney-client privilege and work-product doctrine, the Company will provide
Parent and Merger Sub, and Parent and Merger Sub will provide the Company, with
true, complete and correct copies of all correspondence, filings and
communications (or memoranda setting forth the substance thereof) between such
party or any of its representatives, on the one hand, and any governmental
agency or authority or members of their respective staffs, on the other hand,
with respect to this Agreement and the transactions contemplated hereby;
provided, however, that Parent and Merger Sub shall not be required to provide
the Company with copies of confidential documents or information included in
Parent's filings and submissions under the HSR Act.

         6.9      Public Announcements.  Upon execution of this Agreement, an
appropriate public announcement of the transactions contemplated hereby, the
form and substance of which shall have been agreed to by Parent and the
Company, shall be made; provided, that no such announcement shall be made
unless and until it shall comply with Rule 14d-2 under the Exchange Act.  So
long as this Agreement is in effect and subject to Section 6.5(b), neither
Parent nor the Company shall make any other press release or other written
public statement concerning the transactions contemplated by this Agreement,
including the Offer and the Merger, without the approval of the other party
hereto; provided, however, that either Parent or the Company may, without such
approval, make such press releases or other written public statements as are
required by law, and shall consult with the other party with respect to the
form and substance of such statements.

         6.10     Directors.  The Company will comply with the requirements of
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, so
that, upon the acceptance for payment of, and payment for, any Shares by Merger
Sub pursuant to the Offer which, when taken together with any Shares which
Parent beneficially owns (as such term is defined under the Exchange Act),
represent at least a majority of the then outstanding Shares, Merger Sub shall
be entitled at such time to designate the directors on the Board of Directors
of the Company, and the Company shall, at such time,  obtain resignations of
all then-serving Directors and, prior to such resignations, cause Merger

                                       30
<PAGE>   155

Sub's designees to be elected to, and to constitute all of,  the Board of
Directors of the Company.  The Company agrees to cooperate in permitting the
exercise by Merger Sub of its rights under this Section 6.10, including,
without limitation, (x) cooperating in satisfying the requirements of
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and
(y) amending, prior to the expiration date of the Offer, any provisions of the
By-Laws or any agreement by which the Company is bound that could delay or
hinder the ability of Merger Sub or Parent to elect its designees to a majority
of the directorships constituting the Board of Directors of the Company.  The
Company will not take any action to delay or hinder such election.

         6.11     Directors' and Officers' Insurance Coverage.

                  (a)      For six years after the earlier of (i) the date on
which the designees of Merger Sub have been elected to the Board of Directors
of the Company pursuant to Section 6.10 hereof and constitute all the members
thereof and (ii) the Effective Time, Parent and the Surviving Corporation shall
indemnify, defend and hold harmless the present officers, directors, employees
and agents of the Company and its Subsidiaries (each an "Indemnified Party")
against all losses, claims, damages, liabilities, fees and expenses (including
reasonable fees and disbursements of counsel) and judgments, fines, losses,
claims, liabilities and amounts paid in settlement (provided that any such
settlement is effected with the prior written consent of Parent or the
Surviving Corporation, which consent shall not be unreasonably withheld))
arising out of actions or omissions occurring at or prior to the Effective Time
(including without limitation matters arising out of or pertaining to the
transactions contemplated by this Agreement) to the full extent permitted by
the DGCL or the Company's certificate of incorporation or bylaws as in effect
at the date hereof, including provisions therein relating to the advancement of
expenses incurred in the defense of any action or suit; provided, however, that
in the event any claim or claims are asserted or made within such six-year
period, all rights to indemnification in respect of any such claim or claims
shall continue until disposition of the claim to which such rights are
applicable.

                  (b)      For two years after the Effective Time, Parent and
the Surviving Corporation will (i) maintain the current policies of officers'
and directors' liability insurance in respect of acts or omissions (including
without limitation matters arising out of or pertaining to the transactions
contemplated by this Agreement) occurring at or prior to the Effective Time
covering each person who is an officer or director of the Company on the date
hereof and who is currently covered by the Company's officers' and directors'
liability insurance policy, or (ii) substitute policies providing substantially
similar coverage containing terms and conditions that, taken together, are not
materially less advantageous, and provided that such substitution does not
result in gaps or lapses in coverage.

                  (c)      Parent and the Surviving Corporation shall pay all
expenses (including attorneys' fees) that may be incurred by any Indemnified
Party or person having rights to coverage pursuant to this Section 6.11
(collectively, "Covered Persons") in enforcing the obligations of Parent and
the Surviving Corporation provided for in this Section 6.11, provided that no
such expenses shall be payable if such Indemnified Party or person is found, in
or as a result of such enforcement action, not to have the rights to coverage
claimed by such Indemnified Party or person.  The parties hereto acknowledge
and agree that the remedy at law for any breach of the obligations under this
Section

                                       31
<PAGE>   156

6.11 is and will be insufficient and inadequate and that the Covered Persons,
in addition to any remedies at law, shall be entitled to equitable relief.
Without limiting any remedies Covered Persons may otherwise have hereunder or
under applicable law, in the event of nonperformance of any obligation under
this Section 6.11, the Covered Persons shall have, in addition to any other
rights at law or equity, the right to specific performance.

                  (d)      The rights under this Section 6.11 are contingent
upon, and shall survive, the consummation of the Offer, are intended to benefit
the Company, the Surviving Corporation and each Covered Person, shall be
binding on all successors and assigns of Parent and the Surviving Corporation
and shall be enforceable by each Covered Person, each of whom shall be a third
party beneficiary of this Section 6.11.

         6.12     Benefit Plans and Certain Contracts.

                  (a)      Parent hereby agrees to cause the Surviving
Corporation to pay, in accordance with their terms as in effect on the date
hereof, all amounts due and payable under the terms of all written employment
contracts, agreements, plans, policies and written commitments of the Company
and its Subsidiaries with or with respect to its current employees, officers
and directors as such contracts, agreements, plans, policies and written
commitments are described in the Company Disclosure Schedule.  For at least two
years following the Effective Time, each employee of the Company and its
Subsidiaries (while such person remains an employee of the Company and its
Subsidiaries) shall be entitled to participate in all Benefit Plans maintained
or sponsored by the Company or in benefit plans providing substantially similar
benefits.

                  (b)      Upon or prior to the consummation of the Offer,
Parent and the Company shall enter into an employment agreement with Dewey F.
Edmunds (the "Employment Agreement").

                  (c)      Nothing contained in this Agreement (other than as
specifically provided in the Employment Agreement), including, without
limitation, this Section 6.12, shall confer on any person not a party to this
Agreement, or constitute or be evidence of any agreement or understanding,
express or implied, that any person has a right to be employed as an employee
of or consultant to Parent or the Surviving Corporation for any period of time
or at any specific rate of compensation, or that any employee or other person
shall have a right to participate in any benefit plans maintained by Parent, or
to receive any equity or options to acquire equity in the Company or Parent.


                            ARTICLE 7 -- CONDITIONS

         7.1      Conditions to Obligation of each Party to Effect the Merger.

decree, temporary restraining order, preliminary injunction or permanent
injunction or other order or legal restraint or prohibition preventing the
consummation of the Merger shall have been issued by any Governmental Entity
and shall remain in effect; and

                  (c)      All authorizations, consents, orders or approvals

Offer in accordance with its terms.


                 ARTICLE 8 -- TERMINATION, AMENDMENT AND WAIVER

         8.1      Termination.  This Agreement may be terminated at any time

of Parent and the Company;

                  (b)      by Parent if (i) neither Parent nor any subsidiary
of Parent shall have accepted for payment any Shares pursuant to the Offer by
the sixtieth day following commencement of the Offer and such failure is not in
breach of the Offer or this Agreement, or (ii) Parent has properly terminated
the Offer in accordance with its terms; provided that Parent may not terminate
this Agreement pursuant to this Section 8.1(b) if (A) the failure of Parent or
Merger Sub to fulfill any obligation under this Agreement has been the cause
of, or resulted in, the circumstances described in clause (i), or (B) in the
case of clause (ii), Parent or Merger Sub has not exercised such right by the
close of business on or before the fifth business day following the termination
of the Offer in accordance with its terms;

                  (c)      by Parent and Merger Sub prior to the purchase of

<PAGE>   158


                  (e)      by the Company, if (i) the Offer shall not have been
commenced on or before the fifth business day after the announcement to the
public of the execution of this Agreement, (ii) the Offer is terminated without
the purchase of any Shares and such termination is in breach of the Offer or
this Agreement, or (iii) Parent or Merger Sub has failed to pay or to cause
another entity to pay for Shares duly and properly tendered in the Offer within
10 business days following expiration of the Offer, provided that the Company
may not terminate this Agreement pursuant to this Section 8.1(e) if the failure
of the Company to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the circumstances described in clauses (i), (ii) or
(iii) hereof;

                  (f)      by the Company or by Parent and Merger Sub prior to
the purchase of Shares pursuant to the Offer, if a Superior Acquisition
Proposal is received and the Board of Directors of the Company, pursuant to
Section 6.5(b),  withdraws or modifies its recommendation of the Offer or
recommends to the stockholders of the Company that such stockholders tender
their Shares into, or vote in favor of, such Superior Acquisition Proposal,
provided that termination pursuant to this Section 8.1(f) shall not affect the
Company's obligations under Section 6.3 hereof; or

                  (g)      by the Company or by Parent and Merger Sub if there
shall be any law or regulation that make consummation of the Merger illegal or
otherwise prohibited or if any judgment, injunction, order or decree enjoining
Parent, Merger Sub or the Company from consummating the Merger is entered and
such judgment, injunction, order or decree shall become final and
nonappealable.

         8.2      Effect of Termination.  In the event of termination of this
Agreement prior to the purchase of Shares as provided in Section 8.1, this
Agreement shall forthwith become void and of no effect, and there shall be no
liability on the part of Parent, Merger Sub or the Company, except that (a) the
provisions of Section 6.3, this Section 8.2 and Article 9 hereof shall survive
any such termination, and (b) nothing herein will relieve any party from
liability for any willful or grossly negligent breach of any representation or
warranty or any breach prior to such termination of any covenant or agreement
contained herein.  Except as set forth herein, the provisions of this Section
8.2 shall constitute the exclusive remedy of the parties in the event of
termination of this Agreement prior to the purchase of Shares.

         8.3      Amendment.  This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties, and provided
that any amendment effected after obtaining the Company Stockholder Approval
may be subject to further approval of the Company's stockholders if required by
the DGCL.

         8.4      Extension; Waiver.  At any time prior to the Effective Time,
any party hereto may (a) extend the time for the performance of any of the
obligations or other acts of any other party hereto or (b) waive compliance
with any of the agreements of any other party or with any conditions to its own
obligations.  Any agreement on the part of a party hereto to any such extension
or waiver shall be valid if set forth in an instrument in writing signed on
behalf of such party by a duly

                                       34

authorized officer.  The failure of any party to this Agreement to assert any
of its rights under this Agreement or otherwise shall not constitute a waiver
of those rights.

         9.3      Interpretation.  When a reference is made in this Agreement
to subsidiaries of Parent or the Company, the word "subsidiaries" or
"Subsidiaries" means any corporation more than fifty percent (50%) of whose
outstanding voting securities are directly or indirectly owned by Parent or the
Company, as the case may be.  All references in this Agreement to the Company
conducting business in the ordinary course or in a manner consistent with past
practice shall be considered in light of the Company's financial condition
prior to and as of the date indicated in the applicable reference.  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.

         9.4      Entire Agreement; No Third Party Beneficiaries.  This
Agreement (including the Appendix hereto and the documents and instruments
referred to herein) constitutes the entire agreement and supersedes all other
prior agreements and undertakings, both written and oral, among the parties, or
any of them, with respect to the subject matter hereof, provided, however, that
(i) Paragraph 5 of the letter of intent dated December 24, 1996 between the
Company and Parent, (ii) the Credit Agreement, dated as of December 24, 1996,
by and among Parent, the Company and Insight Imaging Systems, Inc., (iii) the
Subordination and Intercreditor Agreement, dated December 24, 1996, by and
among Coast Business Credit, a division of Southern Pacific Thrift & Loan
Association, Parent, the Company and Insight Imaging Systems, Inc. and (iv) the
Mutual Confidential Non-Disclosure Agreement, dated October 8, 1996, between
Parent and the Company, shall remain in effect in accordance with their terms.
Except as provided in Section 4.7 and 6.11, there are no third party
beneficiaries of this Agreement and nothing in this Agreement, express or
implied, is intended to or shall confer upon any person other than the parties
hereto and their respective successors and permitted assigns, any rights,
remedies, obligations or liabilities.

         9.5      Assignment.  Neither this Agreement nor any of the rights,
interests or obligations hereunder may be assigned by operation of law or
otherwise, provided that Parent or Merger Sub may assign its rights and
obligations hereunder to a direct or indirect subsidiary of Parent, but no such
assignment shall relieve Parent or Merger Sub, as the case may be, of its
obligations hereunder.  Subject to the foregoing sentence, this Agreement will
be binding upon, and inure to the benefit of, the parties and their respective
successors and assigns.

         9.6      Governing Law.  This Agreement shall be governed in all
respects, including validity, interpretation and effect, by the laws of the
State of Delaware, without giving effect to the conflicts of law principles
thereof.

         9.7      Counterparts.  This Agreement may be executed in one or more
counterparts which together shall constitute a single agreement.

         9.8      Specific Performance.  The parties hereto agree that
irreparable damage would occur in the event any of the provisions of this
Agreement were not performed in accordance with the terms hereof and that the
parties shall be entitled to specific performance of the terms hereof, in
addition to any other remedy at law or in equity.

inaccuracy or incompleteness would not reasonably be expected to have a
Material Adverse Effect on the Company, (ii) for changes specifically permitted
by this Agreement or (iii) those representations and warranties that address
matters only as of a particular day must be accurate and complete as of such

forth in that certain Amended and Restated Loan and Security Agreement, dated

proceed with such acceptance for payment or payment or makes it advisable to
terminate or amend the Offer.

         3.       The foregoing conditions are for the sole benefit of Parent
and Merger Sub and may be asserted by Parent and Merger Sub regardless of the

parties conducted heretofore with respect to any Acquisition Proposal. The
Stockholder will immediately communicate to Parent the terms of any proposal,

limited to, investment bankers, attorneys and accountants, not to), directly or
indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with, or provide any information to, any corporation, partnership,
person or other entity or group (other than Parent, any of its affiliates or

immediately cease any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any Acquisition Proposal. The
Stockholder will immediately communicate to Parent the terms of any proposal,
discussion, negotiation or inquiry such Stockholder, in its or his capacity as
a stockholder of the Company, receives (and will disclose any written materials

limited to, investment bankers, attorneys and accountants, not to), directly or
indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with, or provide any information to, any corporation, partnership,
person or other entity or group (other than Parent, any of its affiliates or

immediately cease any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any Acquisition Proposal. The
Stockholder will immediately communicate to Parent the terms of any proposal,
discussion, negotiation or inquiry such Stockholder, in its or his capacity as
a stockholder of the Company, receives (and will disclose any written materials

the certificates representing such Shares are now, and at all times during the

         WHEREAS, DENTSPLY and New Image are parties to an Agreement and Plan

         WHEREAS DENTSPLY and New Image desire that the Employee continue as an

covenants contained herein, DENTSPLY, New Image and the Employee, each
intending to be legally bound hereby, agree as follows:

hereby accepts employment with New Image, for


<PAGE>   284



the Term (as defined in Section 3 hereof) and upon the terms and conditions
contained in this Agreement.

         2.  POSITION AND DUTIES.

                  (a) During the Term, Employee shall serve as Vice President
and General Manager of New Image or any entity (including a division of
DENTSPLY) that succeeds to all or any substantial part of the business and
operations of New Image. Employee shall be responsible for the day-to-day
management and operations of New Image or any such successor entity and shall
report to the Senior Vice President, Pacific Rim, Latin America, Gendex and

or its successor's principal place of business, which shall be Carlsbad,

                  (b) Employee shall at all times devote his full business time
and efforts to the performance of his duties and to promote the best interests
of the Company and its Affiliates (as defined below).

                  (a) For all of the services rendered by the Employee to New
Image pursuant to this Agreement, Employee shall be entitled to receive the
following monetary compensation:

                             i)    New Image shall pay Employee an annual base
salary of not less than $180,000, or such larger amount as may from time to
time be fixed by DENTSPLY (the "Base Salary"), payable in approximately equal
installments (not less frequently than monthly) in accordance with New Image's
regular payroll practices in effect from time to time. The Base Salary may be
increased from time to time by action of DENTSPLY.

                                      -2-


<PAGE>   285



                            ii)    Employee shall be entitled to bonus
compensation that is comparable (in the manner in which it is determined and
with respect to the timing of payment) to that of DENTSPLY's domestic executive
employees who perform duties and have responsibilities comparable to those of
Employee.

                  (b) Throughout the Term, Employee shall be entitled to
participate in all plans and other benefits made available by DENTSPLY
generally to its domestic executive employees who perform duties and have
responsibilities comparable to those of Employee, including (without
limitation) benefits under any pension, profit sharing, employee stock
ownership, stock option, bonus, performance stock appreciation right,
management incentive, vacation (of not less than three (3) weeks each year),
disability, annuity or insurance plans or programs. Employee's service to New
Image prior to the Effective Date shall be credited toward the service
requirements, if any, of such plans or programs. Any payments to be made to
Employee under the provisions of section 6 or 7 of this Agreement shall not be
diminished by any payments made or to be made to Employee or his designees
pursuant to any such plan, nor shall any payments to be made to Employee or his
designees pursuant to any such plan be diminished by any payment made or to be
made to Employee under the provisions of section 6 or 7.

                  (c) Employee shall be eligible to participate in DENTSPLY's
1993 Stock Option Plan. Following the Effective Date, DENTSPLY management will
recommend to the Compensation Committee of the DENTSPLY Board of Directors that
Employee be granted options under such plan in an amount that is determined in
a manner comparable to the manner in which option grants are determined for
DENTSPLY's domestic executive employees who perform duties and have
responsibilities comparable to those of Employee.

         5.  DISCHARGE.

                  (a) Employee may terminate this Agreement upon thirty (30)
days' prior written notice delivered to New Image within thirty (30) days after
the occurrence of one or more of the following events:

                             i)    failure by DENTSPLY or New Image to maintain
the duties, status and responsibilities of the Employee

                                      -3-


<PAGE>   286



substantially consistent with those of Employee's position following the
Effective Date; or

                            ii)    a reduction in Employee's then current Base
Salary, other than any reduction implemented as part of a formal austerity
program approved by the Board of Directors of DENTSPLY and applicable to all
continuing employees of DENTSPLY and New Image, provided such reduction does
not reduce Employee's salary by a percentage greater than the average reduction
in the compensation of all employees who continue as employees of DENTSPLY and
New Image during such austerity program; or

                           iii)    the failure of DENTSPLY to maintain and to
continue Employee's participation in DENTSPLY's benefit plans as in effect from
time to time on a basis substantially equivalent to the participation and
benefits of employees of DENTSPLY similarly situated to the Employee; or

                            iv)    a change in the location where Employee is
required to perform his services hereunder to any location that is greater than
20 miles from the current location without Employee's prior consent; or

                             v)    any substantial and uncorrected breach of
the Agreement by either DENTSPLY or New Image.

                  (b) This Agreement shall terminate as of the date of
Employee's death.

                  (c) New Image may terminate the Employee's employment for
Disability by giving the Employee thirty (30) days' prior written notice. For
all purposes under this Agreement, "Disability" shall mean that the Employee,
at the time notice is given, has been unable to substantially perform his
duties under this Agreement for a period of not less than six (6) months as the
result of his incapacity due to physical or mental illness, despite reasonable
accommodation by New Image. In the event that the Employee resumes the
performance of substantially all of his duties hereunder before the termination
of his employment under this section becomes effective, the notice of
termination shall automatically be deemed to have been revoked.

                                      -4-

         6.  PAYMENT UPON DISCHARGE.

                  (a) Upon termination of Employee's employment for whatever
reason, Employee shall be entitled to receive the compensation accrued and
unpaid as of the date of his termination. If (i) Employee at the time of
termination is eligible to receive bonus compensation or is otherwise
participating in an incentive or bonus plan maintained by DENTSPLY or New Image
and (ii) a bonus or other form of incentive payment becomes payable with
respect to the year in which termination of Employee's employment occurred,
Employee shall be entitled to receive a pro-rata share of such bonus
compensation or other incentive or bonus award based upon the number of days he
is employed during the year up to the date of his termination. Such pro-rata
amount shall be calculated in the usual way and paid at the usual time.

                  (b) If Employee's employment terminates upon the death 
of Employee, New Image shall continue payment of (i) his then current Base
Salary for a period equal to the longer of the remainder of the Term or 12
months from the termination date, and (ii) his pro-rata share of any incentive
or bonus payments due for the period prior to the termination date. Such
payments shall be made (x) in the case of death, to Employee's designated
beneficiary or, if no beneficiary has been effectively designated, then to
Employee's estate, and (y) in the case of Disability, to Employee.

                  (c) If Employee's employment is terminated by the Employee
under section 5(a) or by New Image for any reason other than for "Cause" (as
defined below) or Employee's death, New Image shall continue to pay compensation
and provide benefits to the Employee as provided in this section 6(c) for a
period (the "Termination Period") beginning on the date of the termination
notice and ending on the later of the second anniversary of such date or
February 28, 1999, as follows:

                             i)    Compensation shall be paid to the Employee
at the rate of Base Salary in effect immediately before the termination;

                            ii)    Bonus and incentive compensation shall be
paid to the Employee in accordance with plans in which the

                                      -5-


<PAGE>   288



Employee participated at the termination date, using the same formula and
calculations as if termination had not occurred;

                           iii) Employee shall receive the benefits that
would have been accrued by the Employee during the Termination Period under any
pension, profit sharing, employee stock ownership plan ("ESOP") or similar
retirement plan or plans of DENTSPLY or New Image in which the Employee
participated immediately before the termination (or, if not available, in lieu
thereof Employee shall be compensated for such benefits), based on service the
Employee would have had during the Termination Period and on the compensation
(including, if applicable, bonus and incentive compensation) as determined
under subsections (i) and (ii) above;

                            iv)    Employee shall receive continued coverage
during the Termination Period under all employee disability, annuity, insurance
or other employee welfare benefit plans, programs or arrangements of DENTSPLY
or New Image in which Employee participated immediately before the notice of
termination, plus all improvements subsequent thereto (or, if not available, in
lieu thereof Employee shall be compensated for such coverage).

Except as provided in section 7, payment of compensation under subsection
6(c)(i) above shall be made at the same time as payments of compensation under
section 4(a), and payments of other benefits under subsection 6(c)(ii) and
(iii) shall be paid at the same time and to the same person as compensation or
benefits would have been paid under the plan, program or arrangement to which
they relate (after taking into account any election made by the Employee with
respect to payments under such plan, program or arrangement).

         (d) In no event will New Image or DENTSPLY be obligated to continue
Employee's compensation and other benefits under this Agreement if Employee's
employment is terminated because of gross negligence or significant willful
misconduct (i.e., conviction of misappropriation of corporate assets or heinous
criminal offense) (any of the foregoing, "Cause").

         (e) In no event shall the Employee be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Employee under any of the

                                      -6-

provisions of this Agreement and such amounts shall not be reduced whether or
not the Employee obtains other employment.

         7.  CHANGE OF CONTROL. If at any time during the Term after a Change of
Control (as defined below), Employee's employment is terminated by the Employee
pursuant to section 5(a), or DENTSPLY or New Image terminates or gives written
notice of termination to the Employee, then in lieu of the periodic payment of
the amounts specified in subsections 6(c)(i), (ii) and (iii) (except as may be
otherwise prohibited by law or by said plans), DENTSPLY and New Image, at the
written election of Employee, shall pay to Employee within five (5) business
days of such termination or notice of termination the present value of the
amounts specified in subsection 6(c)(i), (ii) and (iii), discounted at the
greater rate of interest then payable by Bank of America on any federally
insured savings account into which Employee could deposit such amount and make
immediate withdrawals therefrom without penalty, and shall provide for the
remainder of the Termination Period, if any, the benefit coverage required by
subsection 6(c)(iv).

         8.  PRIOR AGREEMENTS.  The Employee represents to New Image that:

the Employee is a party or by which he is bound which would prevent or make

the conditions hereof; and (d) Employee acknowledges that this Agreement
