                            Lakewood, Colorado 80228

         This information statement (the "Information Statement") is furnished
by the Board of Directors (the "Board") of Ustman Technologies, Inc., a
California corporation (the "Company"), to holders of the outstanding shares of
common stock, no par value per share (the "Common Stock"), of the Company in
connection with the written consent of stockholders representing a majority of
the issued and outstanding shares of the Company approving: (i) the sale of
substantially all of the assets of the Company (the "Proposed Sale") to
Veeder-Root Service Company ("Veeder-Root"), a wholly-owned subsidiary of
Danaher Corporation, (ii) the orderly dissolution and liquidation of the Company
and the payment of the net proceeds of the Proposed Sale pursuant to a plan of
liquidation (the "Plan of Liquidation"), and (iii) amending the Company's
Articles of Incorporation to change the Company's name within fifteen (15) days
after the closing of the Proposed Sale to "UST Liquidating Corporation". The
Proposed Sale is to be effected pursuant to that certain Asset Purchase
Agreement dated as of July 21, 2000 (the "Asset Purchase Agreement") between the
Company and Veeder-Root for an aggregate purchase price of $17,158,000 in cash
(the "Purchase Price"). The Company expects, that after the payment of (i) all
legal, accounting, investment banking and other fees and expenses related to the
Proposed Sale, (ii) the repayment in full of the $1.75 million in principal plus
accrued interest thereon of approximately $________________ to the Company's
secured lender BankBoston, and (ii) the partial repayment of the approximately
$17,500,000 liquidation preference of the Company's issued and outstanding
Series A Convertible Preferred Stock (the "Series A Preferred Stock"), there
will not be any proceeds available for distribution to the holders of the
Company's Common Stock. The purpose of this Information Statement is to inform
the Company's shareholders of certain actions that have been taken by the
Company pursuant to the unanimous approval by its Board of Directors (the
"Board") and the written consent of the holders of a majority of the outstanding
shares of Common Stock .

         Since the Proposed Sale involves a sale of assets, the stockholders of
the Company will retain their equity interest in the Company following its
consummation. However, upon the closing of the Proposed Sale, the Company will
dissolve and liquidate and pay out the net proceeds of the Proposed Sale to the
holders of the Company's Series A Preferred Stock. Because it is anticipated
that the net proceeds of the Proposed Sale will not exceed the approximately
$17.5 million liquidation preference of the Series A Preferred Stock, there will
not be any proceeds available for distribution to the holders of the Company's
Common Stock.

         Sagaponack Partners, L.P., a Delaware limited partnership, and
Sagaponack International Partners, L.P., a Cayman Islands exempted limited
partnership (collectively, "Sagaponack"), beneficially own, in the aggregate,
approximately 50.2% of the issued and outstanding Common Stock of the Company.
As a result, Sagaponack beneficially owns a majority of the issued and
outstanding securities of the Company entitled to vote at any meeting to
consider the Proposed Sale. On July 21, 2000, Sagaponack executed and delivered
to the Company a written consent in lieu of a meeting of shareholders (the
"Consent") approving the Asset Purchase Agreement and the Proposed Sale.

         WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US
A PROXY.

                                             Company on April 1, 2002, and the
                                             remaining unused portion of the
                                             hold back will be paid to the
                                             Company on April 1, 2003. The
                                             Company intends to use the proceeds
                                             of the Proposed Sale (i) to repay
                                             in full the entire principal amount
                                             of $1.75 million credit facility
                                             currently outstanding to Bank
                                             Boston, plus accrued interest
                                             thereon, (ii) pay the costs
                                             (including taxes) of effecting the
                                             Proposed Sale, and use the
                                             remainder to repay the
                                             approximately $17.5 liquidation
                                             preference with respect to the
                                             Series A Preferred Stock. Because
                                             it is anticipated that the proceeds
                                             of the Proposed Sale will not
                                             exceed the approximately $17.5
                                             million liquidation preference of
                                             the Series A Preferred Stock, there
                                             will not be any proceeds available
                                             for distribution to the holders of
                                             the Company's Common Stock. Upon
                                             the closing of the Proposed Sale,
                                             the Company will effect a Plan of
                                             Liquidation.

Tax Consequences........................     The Proposed Sale will be a taxable
                                             transaction of the Company for
                                             United States federal income tax
                                             purposes and will result in a
                                             taxable gain to the Company of
                                             $8,000,000. Although the Company
                                             does not expect to pay regular
                                             income tax on the gain because it
                                             has available to it a net operating
                                             loss carry forward, the Company
                                             does, however, anticipate that it
                                             may be subject to an alternative
                                             minimum tax of approximately
                                             $172,000.

                                             date in the event that certain
                                             conditions are not met and for
                                             certain other reasons, including,
                                             without limitation, the Company may
                                             terminate the Asset Purchase
                                             Agreement to pursue an acquisition
                                             proposal. Under certain
                                             circumstances, including but not
                                             limited to termination by the
                                             Company to pursue an acquisition
                                             proposal, the Company will be
                                             required to pay to Veeder Root a
                                             termination fee in the amount of

               REQUIRED VOTE; WRITTEN CONSENT IN LIEU OF MEETING.

         Under the California General Corporation Law (the "CGCL") and the
Company's Articles of Incorporation, the affirmative vote of holders of a
majority of the voting power of the outstanding shares of Common Stock is
required to (i) approve the Proposed Sale, (ii) approve the Plan of Liquidation,
and (iii) amend the Company's Articles of Incorporation at a duly convened
meeting of the shareholders of the Company called for such purpose. Pursuant to
Section 603 of the CGCL, any action required by the CGCL to be taken at any
meeting of shareholders of the Company may be taken without a meeting, without
prior notice and without a vote of the shareholders of the Company if a written
consent, setting forth the action to be taken, is signed by the holders of a
majority of the votes entitled to be cast at such meeting of shareholders. On
July 21, 2000, Sagaponack executed and delivered to the Company the consent
approving the Asset Purchase Agreement and the Proposed Sale. Sagaponack owns
approximately 50.2%, or an aggregate of 11,189,461 shares, of the 22,298,598
issued and outstanding shares of the Company's Common Stock. On August 16, 2000,
Sagaponack executed and delivered a consent to the Company approving the Plan of
Liquidation. Sagaponack has also agreed, upon the closing of the Asset Purchase
Agreement, to cause the Company's Articles of Incorporation to be amended to
change the name of the Company to UST Liquidating Corporation. As the holder of
the majority of the outstanding shares of the Company's Common Stock, Sagaponack
has the power to approve or disapprove any corporate action that is subject to a
vote of the Company's shareholders, in each case, regardless of how the other
shareholders of the Company may vote. Rule 14c-2(b) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") requires that this Information
Statement be sent to


                                       6

shareholders at least 20 calendar days prior to the >earliest date on which
the Merger may be effective. The closing of the Asset Purchase Agreement and the
Proposed Sale is expected to be effected as soon as practicable subsequent to
the 20th day following the date of mailing of this Information Statement.

                        BACKGROUND OF THE PROPOSED SALE.

         The Company's business is principally providing leak detection services
to owners and operators of underground storage tanks. The Company provides this
service using a methodology known as Statistical Inventory Reconciliation
("SIR"). For the past couple of years, the Company believes that it has been at
a competitive disadvantage because it only offered its clients the SIR
methodology, and did not also offer its clients a leak detection technology
known as Automatic Tank Gauge ("ATG") technology. ATG technology automates the
data collection process, and as compared to the SIR methodology, monitors the
tanks more frequently and provides more accurate real-time leak detection. ATG
technology is also more reliable and faster, although it is more expensive than
the SIR methodology used by the Company. As a consequence, for a number of years
the Company has been trying to find a way to offer its clients ATG technology in
addition to its SIR methodology. To this end, the Company has attempted to
develop its own ATG technology, but has lacked the financial resources to do so.
The Company has also tried to purchase a manufacturer of the ATG technology, but
it has been unable to come to terms with any seller. The Company has also
attempted to explore joint ventures and/or licensing arrangements with various
entities. None of these efforts had been successful. During this time,
management has continually advised the Board that unless the Company can offer
ATG technology to its clients, the Company risks losing some of its larger
clients to other providers offering this technology.

         In seeking a potential joint venture and/or licensing arrangement, the
Company spoke with, among others, Veeder-Root, a wholly-owned subsidiary of
Danaher Corporation, and the most prominent company in the industry. After
extensive discussions with Veeder-Root, neither a joint venture, licensing nor
any other transaction could be agreed upon. As an outgrowth of these
discussions, however, the Company and Veeder-Root began discussing a possible
acquisition of the Company by Veeder-Root. Consequently, after significant
negotiations with Veeder-Root, on June 6, 2000, the Company entered into a
definitive Letter of Intent with Veeder-Root to sell substantially all of the
assets of the Company for a purchase price of $17.35 million cash, without any
financing contingency, but subject to adjustment for changes in the Company's
balance sheet. The negotiations with Veeder-Root were arms-length, as there are
no pre-existing relationships between the Company and Veeder-Root or Danaher. At
the time the Letter of Intent was executed, the market capitalization of the
Company was approximately $3.8 million, notwithstanding the fact that the
Company owed approximately $2 million in principal ($250,000 of which was
subsequently repaid by the Company in accordance with the terms of the loan),
plus accrued interest, to BankBoston, and the Company's Series A Preferred Stock
had a liquidation preference, including dividends, in excess of $17 million.

         In negotiating the definitive Asset Purchase Agreement, the final
Purchase Price was determined to be $17.158 million in accordance with the
balance sheet adjustments contemplated by the Letter of Intent. On July 21,
2000, the Company and Veeder-Root signed the definitive Asset Purchase Agreement
described below, a copy of which is attached hereto as Annex A.

                  OPINION OF THE COMPANY'S FINANCIAL ADVISORS.

         After signing the Letter of Intent, the Board immediately engaged an
independent investment bank, H.C. Wainwright & Co., Inc. ("Wainwright"), to
provide the Board with a fairness opinion of the Proposed Sale. The Board of the
Company requested Wainwright to provide an opinion as to the fairness from a
financial point of view of the consideration to be received by the Company from
the Proposed Sale. On July 21, 2000, Wainwright delivered its written opinion
(the "Fairness Opinion") which stated that, as of the date of such opinion and
based upon and subject to the assumptions, limitations and qualifications set
forth therein, the consideration to be received by the Company pursuant to the
Asset Purchase Agreement is fair to the Company from a financial point of view.

         Wainwright, founded in 1868, is a Boston based investment bank that
provides integrated research, investment banking and capital markets
capabilities in a variety of growth industries. The Board selected Wainwright to
render the Fairness Opinion based upon its experience and reputation. There is
no relationship between the Company and Wainwright other than the Company's
engagement of Wainwright to render the Fairness Opinion in connection with the
Proposed Sale.

         A copy of the Fairness Opinion is attached hereto as Annex B. The
summary of the Fairness Opinion set forth below is qualified in its entirety by
reference to the full text of the Fairness Opinion. Shareholders are urged to
read the Fairness Opinion carefully in its entirety for the assumptions made,
the procedures followed, the matters considered and the limits of the review
made by Wainwright in connection with such opinion.

         In connection with the Fairness Opinion, Wainwright performed certain
procedures and reviewed with the management of the Company the assumptions on
which such analyses were based. The following is a summary of such analyses and
the results that were reached by Wainwright in rendering the Fairness Opinion.

         In arriving at its opinion, Wainwright reviewed the public business and
financial information relating to the Company, as well as the Asset Purchase
Agreement. Wainwright also reviewed certain other information, including
financial forecasts, provided to it by the Company, and discussed with the
Company's management the business, both past and current, and future prospects
of the Company. Wainwright also considered certain financial stock market data
of the Company, and Wainwright compared that data with similar data for other
publicly-held companies and businesses that Wainwright deemed similar to those
of the Company. Wainwright also considered financial terms, to the extent
publicly available, of certain business combinations and other transactions
which have recently been effected and that Wainwright deemed relevant.
Wainwright also considered such other information, financial studies, analysis,
investigations and financial, economic and market criteria, which it deemed
relevant. In connection with its review and issuance of its opinion, Wainwright
did not assume any responsibility for independent verification of any of the
foregoing information. In addition, Wainwright did not make an independent
evaluation or appraisal of the assets or liabilities, contingent or otherwise,
of the Company, nor was Wainwright furnished with any such evaluations or
appraisals.



                                       8
<PAGE>   9


         Wainwright, in preparing its opinion, stated that its analyses must be
considered as a whole. Selecting portions of its analyses and factors considered
by it, without considering all analyses and factors, could create a misleading
view of the process underlying the Wainwright's opinion. Wainwright also stated
that no company or transaction used in the analyses performed by Wainwright as a
comparison is identical to the transactions contemplated by the Asset Purchase
Agreement. In addition, Wainwright may have given various analyses more or less
weight than other analyses, and may have deemed various assumptions more or less
probable than other assumptions, so that the range of valuation resulting from
any particular analysis undertaken should not be taken to be Wainwright's view
of the actual value of the Company.

         In performing these analyses, Wainwright made numerous assumptions with
respect to performance, general business and economic conditions and other
matters, many of which are beyond the control of the Company. In arriving at its
opinion, Wainwright performed a number of separate and distinct analyses in
order to ascertain and support the conclusions as outlined in the opinion.

         The following is a summary of all material analyses performed by
Wainwright in connection with its opinion.

         Selected Precedent Transactions - Revenue Multiple Valuation

Wainwright reviewed and analyzed the publicly available information and
financial terms of four acquisitions which occurred during the period April 1999
to February 2000. Wainwright compared the publicly available statistics for
these precedent transactions to the relevant financial statistics of the
Proposed Sale based on the aggregate consideration to be received. The multiples
of the precedent transactions compared by Wainwright included, among other
things, the mean/median or otherwise adjustable transaction value of the
acquired entity to the last 12 months mean/median or otherwise adjusted revenues
of the acquired entity. Applying this transaction multiple, Wainwright derived
the implied value for the Company using the relevant financial statistics for
the Company.

         Public Company Trading Valuation Analysis - Revenue Multiple Valuation

         Wainwright noted that although public company valuation is
traditionally based on price earnings ratios, public companies with earnings
losses or an insignificant amount of earnings are often valued based on their
adjusted market value as a multiple of revenues and a historical and forward
looking basis. Given the Company's operating history, taking into account the
uncertainty of the Company's future prospects as a stand-alone entity,
Wainwright stated that it believed that an appropriate method of valuation for
the Company in terms of revenues is Adjusted Market Values as a multiple of the
latest 12 month revenues. Adjusted Market Value as a multiple of revenues is
defined as market capitalization, including dilution, plus total debt less cash
and cash equivalents, divided by the latest 12 months revenues. Wainwright
compared certain financial information of the Company with that of other
companies which had similar recurring revenue streams that Wainwright deemed
comparable to the Company. It was Wainwright's belief that these comparable
companies are currently valued between 0.3x and 1.7x latest 12 month revenues,
with a mean of 1.1x and a median of 1.3x latest 12 month revenues, respectively.
In accordance with the terms of the Asset Purchase Agreement, the



                                       9
<PAGE>   10


Company is valued at approximately 2.6x the latest 12 month revenues, a multiple
that values the Company above the range of its comparables.

         Public Trading Valuation Analysis - EBITDA Multiple Valuation

         Another commonly used public marketplace valuation measures companies
operating under circumstances similar to that of the Company as a multiple of
Adjusted Market Value to EBITDA. EBITDA is defined as pretax income plus
interest expense, less interest income plus depreciation and amortization,
excluding any non-operating income/expense. Compared to companies that generate
similarly recurring streams that Wainwright deemed relevant as comparable to the
Company, it was Wainwright's belief that these companies are currently valued
between 20.8x and 2.0x trailing EBITDA with a mean of 7.6x and median 4.8x
trailing EBITDA, respectively. In accordance with the Proposed Sale, the Company
is valued at approximately 9.0x trailing EBITDA, a multiple that, Wainwright
believes, places the Company in an acceptable range of the comparables.

         The Company does not make, as a matter of course, public forecasts or
projections as to future performance on earnings, operations, profitability or
other financial metrics. However, in connection with its ongoing internal
activities, the management of the Company periodically prepares projections and
financial forecasts with respect to its operations.

         THE PROJECTIONS PROVIDED BY THE COMPANY TO WAINWRIGHT ARE BASED ON MANY
ESTIMATES AND ARE INHERENTLY SUBJECT TO SIGNIFICANT AND COMPETITIVE
UNCERTAINTIES AND CONDITIONS, MANY OF WHICH ARE BEYOND THE CONTROL OF MANAGEMENT
OF THE COMPANY, INCLUDING, WITHOUT LIMITATION, THE EFFECT OF GENERAL ECONOMIC
AND MARKET CONDITIONS, BUSINESS PREDICTIONS, COMPETITION, AND THE AVAILABILITY
OF CAPITAL. ACCORDINGLY, ACTUAL RESULTS MAY MATERIALLY BE HIGHER OR LOWER THAN
THOSE PROJECTED. INCLUSION OF SUCH PROJECTIONS IN WAINWRIGHT'S ANALYSES SHOULD
NOT BE REGARDED AS A REPRESENTATION BY THE COMPANY OR ANY OTHER PERSON THAT SUCH
FINANCIAL FORECASTS OR PROJECTIONS ARE CORRECT.

         Pursuant to the Company's engagement letter with Wainwright dated June
9, 2000, the Company agreed to pay Wainwright a fee for rendering its Fairness
Opinion pursuant to an agreement dated June 9, 2000. Specifically, the Company
agreed to pay Wainwright a fee of $50,000 in cash, as follows: $20,000 upon the
execution of the engagement letter and $30,000 upon completion of the Fairness
Opinion. The Company has also agreed to reimburse Wainwright for its reasonable
out-of-pocket expenses, and to indemnify Wainwright against certain liabilities,
including liabilities relating to or arising out of Wainwright's engagement.

                       APPROVAL BY THE BOARD OF DIRECTORS.

         On July 17, 2000, the Company's Board unanimously approved the Asset
Purchase Agreement and the Proposed Sale, and recommended that each be approved
by the Company's shareholders. In approving the Asset Purchase Agreement and the
Proposed Sale, and recommending the transaction to the Company's shareholders,
the members of the Board considered various factors, including, but not limited
to, the following, all of which they believe support such approval and
recommendation:


                                       10

         (i)      The Company's business, its current financial condition and
                  results of operations, its future prospects and the current
                  and anticipated developments in the Company's industry;

         (ii)     The Board has been advised repeatedly by management that
                  unless it makes a strategic change, i.e., offers ATG
                  technology to its clients, the Company is at risk of losing
                  substantial client revenues which in turn could threaten the
                  economic viability of the Company;

         (iii)    The Company cannot presently afford to invest in the ATG
                  technology and has been unable to raise additional capital to
                  do so;

         (iv)     The Company has explored a variety of transactions in recent
                  years in an attempt to offer ATG technology to its client base
                  but has not been able to consummate any such transaction;

         (v)      The industry in which the Company participates is highly
                  specialized and dominated by relatively few players and, as a
                  consequence, is not attractive either to financial or general
                  business suitors;

         (vi)     The amount offered by Veeder-Root for substantially all of the
                  Company's assets is extremely attractive in light of the
                  Company's current business and prospects; and

         (vii)    Unless the Company completes this transaction with Veeder-Root
                  the business and economic value of the Company is at risk of
                  being significantly impaired.

         In view of the wide variety of factors considered, the Board did not
find it practicable to, and did not, quantify, or otherwise attempt to assign
relative weights to, the specific factors considered or determine that any
factor was of particular importance in reaching its determination that the
Proposed Sale is fair to, and in the best interests of, the Company.

         Upon consummation of the Proposed Sale, the Company will no longer have
any business operations, executive management or employees, and it is
anticipated that the proceeds from the Proposed Sale will be insufficient to
repay the entire approximately $17.5 million liquidation preference of the
Series A Preferred Stock. Accordingly, on August 16, 2000, the Board unanimously
approved the Plan of Liquidation pursuant to which the Company will wind up its
affairs and cease to exist as an operating entity.

 CERTAIN EFFECTS OF THE PROPOSED SALE, PLANS FOR THE COMPANY AFTER THE PROPOSED
               SALE, USE OF PROCEEDS FOLLOWING THE PROPOSED SALE.

         Upon consummation of the Proposed Sale, the Company will no longer have
any operating assets or any ongoing business operations and will cease business
other than winding up its affairs and matters incidental thereto and
distributing the net proceeds of the Proposed Sale to the holders of its Series
A Preferred Stock. The Company expects to make an interim distribution to the
holders of its Series A Preferred Stock shortly after the closing of the
Proposed Sale after paying all fees and costs related to the transaction and all
outstanding bank debt. In


                                       11
<PAGE>   12


addition, upon the closing of the Proposed Sale, it is anticipated that the
Company will delist the trading of its Common Stock from the OTC Bulletin Board.
In accordance with the terms of the Asset Purchase Agreement, $1,500,000 of the
Purchase Price is to be held back by Veeder Root to secure the Company's
indemnity obligations under the Asset Purchase Agreement. Subject to the
indemnity provisions of the Asset Purchase Agreement, one-half of the unused
portion of this hold back is to be paid to the Company on April 1, 2002, and the
remaining unused portion of this hold back is to be paid to the Company on April
1, 2003. Accordingly, the Company anticipates that additional distributions will
be made to the holders of the Company's Series A Preferred Stock shortly after
the release of each of these held back sums.

         Each of the shareholders representing a majority of the Company's
issued and outstanding Common Stock, and the Board of Directors, unanimously,
has approved the Plan of Liquidation. The following is a summary of the material
terms and provisions of the Plan of Liquidation, a copy of which is annexed
hereto to this Information Statement as Annex C and is incorporated herein by
reference in its entirety. This summary is qualified in its entirety by
reference to the full text of the Plan of Liquidation.

         The Plan of Liquidation provides that after the consummation of the
Proposed Sale the Company will not engage in any business except for the
purposes of preserving the value of the Company's assets (which will consist
principally of the proceeds of the Proposed Sale), in order to wind up the
Company's business affairs and make pro-rata distributions (the "Liquidating
Distributions") first, to the holders of the Company's Series A Preferred Stock,
and if there are any assets remaining after payment to the holders of the
Company's Series A Preferred Stock of their entire liquidation preference (which
is not anticipated to be the case), then pro rata to holders of the Company's
Common Stock; except the Company will not distribute those assets required to be
reserved for payment of any claims or obligations of the Company. It is also
further provided that, as promptly as practicable following the consummation of
the Proposed Sale, the Company will first wind up its affairs, and thereafter,
will be dissolved by filing a Certificate of Election to Wind Up and Dissolve
and a Certificate of Dissolution pursuant to the applicable provisions of the
CGCL.

         Pursuant to the Plan of Liquidation, the Board of Directors may, in its
sole discretion, establish a contingency reserve to satisfy any claims against
the Company for expenses incurred in connection with the Plan of Liquidation or
otherwise, including but not limited to, reasonable payments to officers,
directors and outside professionals. Liquidating Distributions will be in
complete redemption of cancellation of all the outstanding shares of Series A
Preferred Stock. Shareholders must surrender their stock certificates (or, if
required by the Board in its absolute discretion, furnish indemnity bonds in
case of lost or destroyed certificates) as a condition of them receiving the
Liquidating Distributions.

         The Plan of Liquidation provides that the Company may indemnify its
officers, directors, employees and agents in accordance with the Company's
articles of incorporation and by-laws. In the event of a vacancy occurring on
the Board for any reason, the remaining Board members (or the surviving officer
if there are no remaining Board members) have the authority to fill the vacancy,
but failure to do so will not impair the authority of the remaining Board
members to exercise the powers provided to them under the Plan of Liquidation.
The Plan of Liquidation provides that the Company may, in the absolute
discretion of the Board, pay the Company's




                                       12
<PAGE>   13


officers, directors and employees additional compensation above their regular
compensation in recognition of any extraordinary contribution they make in
connection with the successful implementation of the Plan of Liquidation.

         The Board of Directors is authorized under the Plan of Liquidation to
establish, if necessary for any reason to complete the Liquidation Distribution,
a liquidating trust into which any remaining assets of the Company may be
transferred to be held as a reserve for contingent liabilities. The Company has
no current plans to use a liquidating trust, but believes the flexibility
provided by the Plan of Liquidation to allow such a trust to be established is
advisable.

         The Company intends to use the proceeds of the Proposed Sale as
follows:

         (i)      Repay in full the entire principal amount of the $1.75 million
                  loan currently outstanding to BankBoston, plus accrued
                  interest thereon, $_______ as of ___________, 2000;

         (ii)     Pay the costs of effecting the transaction, including, but not
                  limited to, legal fees, accounting fees, fees related to the
                  fairness opinion; and

         (iii)    Apply the balance of the proceeds to repay, in part only, the
                  approximately $17.5 million liquidation preference with
                  respect to the Series A Preferred Stock in accordance with the
                  express provisions of the Series A Preferred Stock.

               INTERESTS OF CERTAIN PERSONS IN THE PROPOSED SALE.

         Messrs. Barry S. Rosenstein and Marc A. Weisman, directors of the
Company, are co-managing partners of Sagaponack. Sagaponack owns approximately
50.2% of the issued and outstanding shares of common stock of the Company and
owns 100% of its issued and outstanding shares of Series A Preferred Stock. Each
of Messrs. David Shapiro and Michael Lerner, directors of the Company, are
limited partners of Sagaponack Partners, L.P.

         Dan Cook, the Company's Chief Executive Officer and a director of the
Company, will be employed by Veeder-Root subsequent to the closing of the Asset
Purchase Agreement on terms and conditions substantially similar to the terms of
Mr. Cook's current employment arrangement with the Company.

                                 EFFECTIVE TIME.

         The effective date of the Proposed Sale will be on or about September
___, 2000.

                  CERTAIN INFORMATION CONCERNING THE PURCHASER.

         Veeder-Root is a supplier of fuel management solutions and monitors
over 500,000 petroleum underground storage tanks at retail stations around the
world. Veeder-Root is a wholly-owned subsidiary of the Danaher Corporation, a
public company and a manufacturer of process/environmental and tools and

                               REGULATORY MATTERS.

         Upon providing this Information Statement to shareholders of the
Company, the Company knows of no remaining federal or state regulatory
requirements that must be complied with or approvals that must be obtained in
order to consummate the Proposed Sale.

         ACCOUNTING TREATMENT; CERTAIN FEDERAL INCOME TAX CONSEQUENCES
                              OF THE PROPOSED SALE.

         In accordance with generally accepted accounting principles, any gain
or loss on the sale will be recognized as of the date the Asset Purchase
Agreement is closed.

         The following describes the material federal income tax consequences of
the Proposed Sale to Veeder-Root. It does not attempt to provide tax advice to
any particular shareholder. It does not address state or local tax consequences
nor does it address tax consequences to specialized types of shareholders such
as foreign investors or tax-exempt stockholders. Each shareholder is urged to
discuss the tax consequences of the proposed transaction with his or her own tax
advisor.

         Tax consequences at the corporate level. On the sale of the assets of
the Company, the Company generally will recognize gain for federal income tax
purposes to the extent that the amount realized on such sale of assets exceeds
the Company's basis in any assets being sold. It is presently anticipated that
the Proposed Sale will result in a taxable gain to the Company of approximately
$8,000,000 based on financial information as of March 31, 2000. The Company does
not expect to pay regular income tax on the gain due to the availability of net
operating loss carry forwards. The Company does, however, anticipate that it may
be subject to an alternative minimum tax of approximately $172,000.

         Tax consequences at the stockholder level. Under current tax law, the
Proposed Sale will not have any federal income tax consequences to the
stockholders of the Company.

                              NO APPRAISAL RIGHTS.

         Pursuant to the CGCL, holders of shares of Common Stock will not be
entitled to rights of appraisal in connection with the Proposed Sale.

                          THE ASSET PURCHASE AGREEMENT.

         General

         The following is a summary description of the material terms and
provisions set forth in the Asset Purchase Agreement, and is qualified in its
entirety by reference to the Asset Purchase Agreement, a copy of which is
attached hereto as Annex A. Shareholders are urged to review the Asset Purchase
Agreement in its entirety.

         Terms which are not otherwise defined in the following summary or
elsewhere in this Information Statement shall have the meaning set forth in the
Asset Purchase Agreement.

         Purchase Price

         The Asset Purchase Agreement provides for the sale by the Company to
Veeder-Root of substantially all of the Company's assets, and substantially all
of the assets of the Company's subsidiaries, for an aggregate Purchase Price of
Seventeen Million One Hundred Fifty-Eight Thousand Dollars ($17,158,000). The
Purchase Price is subject to adjustment based upon the difference between the
cash and debt-free net equity of the Company at the Closing Date and the cash

amount of Seven Million Four Hundred Eight Thousand Dollars ($7,408,000).
Veeder-Root will hold back One Million Five Hundred Thousand Dollars

insurance payable to Veeder-Root, all unknown or unasserted liabilities of the

         On July 21, 2000, the Company executed a definitive Asset Purchase
Agreement with Veeder-Root, a wholly-owned subsidiary of Danaher Corporation, a
publicly traded company, to sell substantially all of the assets of the Company
to Veeder-Root for $17,158,000, of which $1,500,000 of the purchase price is to
be held back by Veeder-Root to secure indemnity

obligations of the Company. The Company expects to recognize a net realized gain
and a deferred gain on the transaction, estimated to be approximately $7,922,000
and $1,500,000 respectively, based upon pro forma calculations as if the
transaction had been consummated on March 31, 2000, as discussed below. The
Company presently intends on using the proceeds of the sale to repay
indebtedness not assumed by Veeder-Root, pay transaction expenses and income
taxes on the transaction, and partially pay the liquidation preference of its
Series A Preferred Stock. It is not presently expected that there will be funds
available for distribution to common stockholders.

         Upon consummation of the proposed sale, the Company will no longer have
any business operations, executive management, or employees, and the proceeds
from the proposed sale are expected to be insufficient to repay the entire
amount of the Series A liquidation preference. Accordingly, on August 15, 2000,
the Company's board of directors unanimously approved the Plan of Liquidation,
pursuant to which the Company will wind up its affairs and cease to exist as an
operating entity. Revenues and expenses of the Company subsequent to the
transaction are anticipated to consist primarily of interest income earned on
remaining cash balances and legal and accounting expenses expected to be
incurred in connection with corporate winding up and liquidation. The Company
believes that revenues and expenses subsequent to the transaction will represent
a minimal continuing impact to the Company. As a result, pro forma statements of
operations for periods prior to April 1, 2000, are not presented.

         The accompanying unaudited pro forma condensed consolidated balance
sheet gives effect to the proposed sale as if it had been consummated on March
31, 2000. The unaudited pro forma condensed consolidated balance sheet should be
read in conjunction with the historical consolidated financial statements of the
Company. The unaudited pro forma condensed consolidated balance sheet does not
purport to be indicative of the financial position that actually would have
occurred had the transaction occurred on March 31, 2000, or to project the
Company's financial position to any future period.

1.       Description of the transaction:

         On July 21, 2000, the Company executed a definitive Asset Purchase
         Agreement with Veeder-Root, a wholly-owned subsidiary of Danaher
         Corporation, a publicly traded company, to sell substantially all of
         the assets of the Company to Veeder-Root for $17,158,000, of which
         $1,500,000 of the purchase price is to be held back by Veeder-Root to
         secure indemnity obligations of the Company. One-half of the unused
         portion of the holdback is to be paid to the Company on April 1, 2002,
         and the remaining unused portion of the holdback is to be paid to the
         Company on April 1, 2003. The Company expects to recognize a net
         realized gain and a deferred gain on the transaction, calculated to be
         approximately $7,922,000 and $1,500,000 respectively, based upon pro
         forma calculations as if the transaction had been consummated on March
         31, 2000, as discussed below. The Company presently intends on using
         the proceeds of the sale to repay indebtedness not assumed by
         Veeder-Root, pay transaction expenses, and partially pay the
         liquidation preference of its Series A Preferred Stock. It is not
         presently expected that there will be funds available for distribution
         to common stockholders.

         Upon consummation of the proposed sale, the Company will no longer have
         any business operations, executive management, or employees, and the
         proceeds from the proposed sale are expected to be insufficient to
         repay the entire amount of the Series A liquidation preference.
         Accordingly, on August 14, 2000, the Company's board of directors
         unanimously approved the Plan of Liquidation pursuant to which the
         Company will wind up its affairs and cease to exist as an operating
         entity. Revenues and expenses of the Company subsequent to the
         transaction are anticipated to consist primarily of interest income
         earned on remaining cash balances and legal and accounting expenses
         expected to be incurred in connection with corporate winding up and
         liquidation. The Company believes that revenues and expenses subsequent
         to the transaction will represent a minimal continuing impact to the
         Company. As a result, statements of operations for periods prior to
         April 1, 2000, are not presented.

         The unaudited condensed consolidated balance sheet as of March 31, 2000
         gives effect to the transaction as if it had occurred March 31, 2000.
         The final sales price will be subject to an adjustment for the
         difference between the Company's actual "Cash and Debt Free Net Equity"
         as of the acquisition date and the targeted "Cash and Debt Free Net
         Equity" amount of $7,750,000, as defined.

2.       Description of pro forma adjustments

         (A1) To reflect cash proceeds of $15,658,000 and to reflect a
         $1,500,000 "hold back" receivable from Veeder-Root in exchange for
         Company assets with a carrying value of $8,808,000 and liabilities with
         a carrying value of $1,072,000 at March 31, 2000, resulting in a net
         realized gain of $7,922,000 and a deferred gain of $1,500,000.

         (A2) To reflect transaction expenses, estimated to be approximately
         $275,000, incurred by the Company in connection with the transaction.

         (A3) To reflect estimated current and deferred income taxes totaling
         approximately $172,000 ($145,000 current; $27,000 deferred) incurred in
         connection with the transaction, and based on an estimated total tax
         gain of approximately $8,000,000. Income tax of $172,000 represents
         estimated alternative minimum tax. Regular income tax is not expected
         to be incurred by the Company due to the availability of net operating
         loss carry forwards.

         (B) To reflect the payment of obligations not assumed by Veeder-Root,
         including current and long-term debt, transaction expenses incurred in
         connection with the transaction, and estimated current income taxes.

         (C) To reflect the Company's liquidating distribution of all available
         funds payable to the Series A preferred shareholders in accordance with
         the provisions of the Series A Preferred Stock. At March 31, 2000 the
         Series A Preferred Stock had a liquidation preference of $17,230,285.

Private Securities Litigation Reform Act of 1995. In addition, the Company,
through its senior management, from time to time makes forward-looking public
statements concerning expected future operations and performance and other
developments. Such forward-looking statements are necessarily estimates
reflecting the Company's best judgment based upon current information and
involve a number of significant risks and uncertainties, and there can be no
assurance that other factors will not affect the accuracy of such
forward-looking statements. While it is impossible to identify all such factors,
factors which could cause actual results to differ materially from those
estimated by the Company include, but are not limited to, the Company's
incurring expenses in connection with its winding up, liquidation and
dissolution which are greater than those anticipated, changes in the regulation
of the industrial cleaning industry at either or both of the federal and state
levels, competitive pressures in the industrial cleaning industry and the
Company's response thereto, the general conditions in the economy and capital

California. Seller has the requisite corporate power and authority to own,
operate or lease its properties and to carry on its business as it is now being
conducted, and is duly qualified or licensed to do business, and is in good
standing, in each jurisdiction in which the nature of its business or the
properties owned, operated or leased by it makes such qualification, licensing
or good standing necessary which failure to qualify, be licensed or be in good
standing would have a material adverse effect on the business, operations,
affairs, prospects, properties, assets, profits or condition (financial or
otherwise) of the Business (a "Material Adverse Effect"). Section 3.l of the
Disclosure Schedule contains a list of all jurisdictions in which Seller is
authorized or qualified to do business. Seller has delivered to Buyer true,

transactions contemplated by this Agreement to perform its obligations pursuant
to the terms of this Agreement. The execution and delivery of this Agreement by
Seller and the performance by Seller of the transactions contemplated herein
have been duly and validly authorized by the Board of Directors of Seller and no
other corporate proceedings on the part of Seller are necessary to authorize or
approve this Agreement or to consummate the transactions contemplated hereby
(other than the approval of this Agreement by the affirmative vote of the

entitled to vote thereon, to the extent required by applicable law). This
Agreement has been duly and validly authorized by Seller. This Agreement is a

policies. The revenues of Seller and its subsidiaries for the six month period
ended December 31, 1999, were not less than Three Million Forty-Five Thousand
and 00/100 U.S. Dollars ($3,045,000.00) and the operating profit of Seller and

filing a Proxy Statement and intends to hold the Seller Stockholders Meeting,

enter into negotiations with all of the employees of Seller employed in the
Business for their continued employment with Buyer from and after the Closing

employment to such employees, except that Buyer shall take all actions necessary
or appropriate to permit all employees of Seller who become employees of Buyer

employee benefit plans (including without limitation severance plans, if any)
and salary structure.

                  (b) Notwithstanding the foregoing subsection (a), Buyer shall

inaccurate in any material respect, or (b) any covenant or condition or
agreement contained in this Agreement not to be complied with or satisfied in

policy for a period of six months following the Closing Date, which insurance
policy shall be structured to provide to Buyer and its affiliates insurance
coverage with respect to product liability, personal injury or property damage
arising out of events or occurrences relating to products manufactured or
services provided by Seller or any of its


                                      A-39

<PAGE>   75

                  (b) any and all Damages incident to any of the foregoing or to

         8.2 Limitation and Expiration. Notwithstanding the above:

                  (a) there shall be no liability for indemnification under
Section 8.1 unless, and solely to the extent that, the aggregate amount of
Damages exceeds $250,000 (the "Indemnification Deductible"); provided, however,
that the Indemnification Deductible shall not apply to (i) Damages arising out

Period"), or

                               (2) with respect to representations and
warranties contained in Sections 3.13 and 3.21 and the Excluded Liabilities, on
(A) the date that is the expiration of the longest applicable federal or state
statute of limitation (including extensions thereof), or (B) if there is no
applicable statute of limitation, ten (10) years after the Closing Date; or

                           (ii) the final resolution of claims or demands (a
"Claim") pending as of the relevant dates described in clause (i) of this
Section 8.2(b) (such claims referred to as "Pending Claims").

         8.3 Indemnification Procedures. All Claims for indemnification under
this Article 8 shall be asserted and resolved as follows:

                  (a) In the event that any Buyer Indemnified Party or Seller
Indemnified Party (each, as the case may be, an "Indemnified Party") has a Claim
against any party obligated to provide indemnification pursuant to Section 8.1
hereof (the "Indemnifying Party") which does not involve a Claim being asserted
against or sought to be collected by a third party, the Indemnified Party shall
promptly, but in no event later than ten (10) business days after knowledge of
the Claim, notify the Indemnifying Party of such Claim, specifying the nature of
such claim and the amount or the estimated amount thereof to the extent then
feasible (the "Claim Notice"). If the Indemnifying Party does not notify the
Indemnified Party within thirty (30) days from the receipt of the Claim Notice
(the "Notice Period") that the Indemnifying Party disputes such Claim, the Claim
shall be conclusively deemed a liability of the Indemnifying Party hereunder and
the Indemnifying Party shall have the obligation to promptly pay the Indemnified
Party the actual amount of such Claim. In case an objection is made in writing
in accordance with this Section 8.3(a), the Indemnified Party shall have thirty
(30) days to respond in a written statement to the objection. If after such
thirty (30) day period there remains a dispute


                                      A-44
<PAGE>   76

as to any Claims, the parties shall attempt in good faith for sixty (60) days to
agree upon the rights of the respective parties with respect to each of such
Claims.

                  (b) In the event that any Claim for which the Indemnifying
Party would be liable to an Indemnified Party hereunder is asserted against an
Indemnified Party by a third party, the Indemnified Party shall promptly, but in
no event later than ten (10) business days after knowledge of the Claim, send a
Claim Notice with respect to such Claim to the Indemnifying Party. The
Indemnifying Party shall have the Notice Period to notify the Indemnified Party
(i) whether or not it disputes the liability to the Indemnified Party hereunder
with respect to such Claim and (ii) regardless of whether the Indemnifying Party
disputes liability, whether or not the Indemnifying Party desires to defend the
Indemnified Party against such Claim, at the sole cost and expense of the
Indemnifying Party, provided that the Indemnified Party is hereby authorized
(but not obligated) prior to and during the Notice Period to file any motion,
answer or other pleading and to take any other action which the Indemnifying
Party shall deem necessary to protect the Indemnifying Party's interests. In the
event that the Indemnifying Party notifies the Indemnified Party within the
Notice Period that the Indemnifying Party desires to defend the Indemnified
Party against such Claim and except as hereinafter provided, such party shall
have the right to defend the Indemnified Party by appropriate proceedings, which
proceedings shall be promptly settled or prosecuted by such party to a final
conclusion. The Indemnifying Party shall not, without the prior written consent
of the Indemnified Party, which consent shall not be unreasonably withheld,
settle, compromise or offer to settle or compromise any such Claim on a basis
that (i) would result in the imposition of a consent order, injunction or decree
that would restrict the future activity or conduct of, or have a materially
adverse effect on the assets, liabilities, financial condition, results of
operations or business prospects of, the Indemnified Party or any subsidiary or
Affiliate thereof, (ii) would result in any monetary liability of the
Indemnified Party that will not be paid or reimbursed by the Indemnifying Party,
or (iii) that would not result in a complete and unconditional release of the
Indemnified Party. If the Indemnified Party desires to participate in, but not
control, any such defense or settlement the Indemnified Party may do so at its
sole cost and expense. If the Indemnifying Party elects not to defend the
Indemnified Party against such Claim, whether by failure of such party to give
the Indemnified Party timely notice as provided above or otherwise, then the
Indemnified Party, without waiving any rights against such party, may settle
(after giving notice to the Indemnifying Party and allowing the Indemnifying
Party three (3) days to comment upon the proposed settlement) or defend against
any such Claim in the Indemnified Party's sole discretion and the Indemnified
Party shall be entitled to recover from the Indemnifying Party the amount of any
settlement or judgment and, on an ongoing basis, all indemnifiable costs and
expenses of the Indemnified Party with respect thereto, including interest from
the date such costs and expenses were incurred.

                  (c) If the Indemnifying Party assumes the defense with respect
to any Claim of a third party, the Indemnified Party shall have the right to
participate in the defense thereof and to employ separate counsel reasonably
acceptable to the Indemnifying Party, at the Indemnifying Party's sole expense,
if such Claim involves, in the good faith belief of the Indemnified Party, a
conflict of interest between or substantially different defenses for the
Indemnified Party and the Indemnifying Party.


                                      A-45
<PAGE>   77

                  (d) Any failure of the Indemnified Party's to give prompt
notice as required by this Section 8.3 of any actual, threatened or possible
claim or demand which may give rise to a right of indemnification hereunder
shall not constitute a waiver of the Indemnifying Party's indemnity obligations
hereunder except to the extent that the failure to give such notice materially
prejudiced the Indemnifying Party.

                  (e) The parties will make appropriate adjustments for any Tax
benefits, Tax detriments or insurance proceeds in determining the amount of any
indemnification obligation under Article 8.

         8.4 Manner of Payment. Any indemnification obligations of Seller
pursuant to Section 8.2 shall be paid first by reduction of the Holdback, and
second by wire transfer from Seller of immediately available funds to an account
designated in writing by the applicable Indemnified Party within five (5) days
after the determination thereof.

         8.5 Survival of Representations, Warranties and Covenants. All
representations, warranties and covenants made by Seller and Buyer in or
pursuant to this Agreement or in any document delivered pursuant hereto shall be
deemed to have been made on the date of this Agreement (except as otherwise
specifically provided herein) and, if a Closing occurs, as of the Closing Date.
The representations and warranties of Seller will survive the Closing and will
remain in effect until, and will expire upon, the termination of the relevant
indemnification obligation as provided in Section 8.2. The representations and
warranties of Buyer will survive the Closing and will remain in effect until,
and will expire upon the later of (i) the first anniversary of the Closing Date
or (ii) the date of the final resolution of Claims pending as of the first
anniversary of the Closing Date. The covenants of the parties set forth in this
Agreement shall survive the Closing and shall expire in accordance with their
respective terms.

         8.6 Other Indemnification Matters. Except with respect to matters
involving fraud, the indemnity provided herein shall be the sole and exclusive
remedy of the parties hereto, their Affiliates, successors and assigns with
respect to any and all Claims for losses sustained or incurred arising out of
this Agreement and the transactions contemplated herby; except that, nothing
contained herein shall limit the right of Buyer to seek contribution from Seller
for any Damages arising out of any Excluded Liabilities after the expiration of
the indemnification obligations under this Article 8. Notwithstanding the other
provisions of this Article 8, Buyer agrees that prior to seeking any
indemnification payment from Seller for a specific matter for which Seller is
obligated to indemnify Buyer hereunder (each an "Indemnification Claim"), Buyer
will first use commercially reasonable efforts (which shall not include
expending any funds to third parties or pursuing litigation, arbitration or any
other dispute resolution process) to seek payment of the Indemnification Claim
under any insurance policies (except self-insurance policies) under which
coverage of the Indemnification Claim is available to Buyer; provided, however;
that in the event that Seller shall be unable, because of lack of privity,
because Seller is not a named insured or additional insured under an applicable
insurance policy or because Seller does not otherwise have the legal right, to
seek payment under an insurance policy of the Indemnification Claim, Seller
shall have the right, at Seller's sole cost and expense, and subject to the
succeeding sentences hereof, to commence proceedings against an applicable
insurance company that has refused to provide payment of an amount that is the
subject of an Indemnification Claim. Buyer agrees to cooperate with Seller in
connection with a claim brought


                                      A-46
<PAGE>   78

by Seller as provided in the previous clause against any such insurance company
in any commercially reasonable manner requested by Seller provided that Buyer
shall not be required to incur any cost in doing so. Seller shall have the right
to take any such action against such insurance company in Buyer's name and, for
that purpose and only to such extent, all of the rights of Buyer to enforce the
obligations of such insurance company related to such Indemnified Claim are
hereby conferred upon and conditionally assigned to Seller; provided, further,
however, that Seller shall only have such rights if prior to the commencement of
any such action Seller provides such security (in the form of a guaranty,
deposit or other arrangement) to Buyer as Buyer reasonably deems necessary to
secure Seller's obligation to fund the expenses of any such action and to
indemnify Buyer for the Insurance Indemnification (as later defined). Seller
shall indemnify and hold Buyer harmless from and against any and all losses,
costs, liability, claims, damages, expenses, penalties and fines which Buyer may
incur in connection with or arising out of the taking of any such action by
Seller (the "Insurance Indemnification"). Notwithstanding the foregoing, if
Seller proceeds against an insurance company as contemplated in the foregoing
sentences, Seller shall pay the Indemnification Claim to Buyer prior to
commencing such proceedings.

         8.7 Indemnification by Buyer. From and after the Closing Date, Buyer
shall indemnify, pay, defend, protect and hold harmless Seller and its officers,
directors, employees, stockholders, assigns, successors and affiliated companies
(each a "Seller Indemnified Party") from and against Damages actually suffered,
sustained, incurred or paid by a Seller Indemnified Party as a result of any
breach or inaccuracy contained in any representation or warranty made by Buyer
in this Agreement, any breach of any covenant of Buyer contained in this
Agreement or Buyer's operation of the Business after the Closing Date, or
failure of Buyer to pay or perform any of the Assumed Liabilities; provided that
Buyer shall not be required to indemnify any Seller Indemnified Party under this
Section 8.7 from or against any Damages for which Seller will indemnify a Buyer
Indemnified Party under Section 8.1 of this Agreement.

9. RESTRICTIVE COVENANTS

         9.1 Prohibited Activities.

                  (a) Seller covenants and agrees with Buyer that it shall not,

that compete with the services provided by the Business (collectively, the
"Competitive Products and Services") in direct competition with the Business
anywhere within the United States, South America, Latin, America, Canada, Asia,
Australia, New Zealand and Europe (the geographic locations in this subsection
(a) being the "Territory"). "Competitive Products and Services" includes all
activities of Company that constitute the Business, which includes without
limitation, providing leak detection services to owners and operators of
underground storage


                                      A-47

tanks, licensing fuel management software and selling related fuel management
products, marketing automatic tank gauge systems, and marketing regulatory
compliance software;

                  (ii) solicit any person who is, at that time, within the
Territory, an employee of Buyer or any company affiliated with Buyer that is
engaged in the design, manufacturer, distribution or sale of Competitive
Products and Services for the purpose or with the intent, of enticing such
employee away from or out of the employ of Buyer or any of its Affiliates; or

                  (iii) solicit any person who is or entity that is, at that
time, or that has been, within one year prior to that time, a customer of Buyer
within the Territory for the purpose of soliciting or selling products or
services in competition with the Competitive Products or Services.

         (b) Seller acknowledges and agrees that Seller is a sophisticated
corporation that conducts business throughout the world and that accordingly the
duration and geographic scope of the non-competition provision set forth in this
Section 9.1 are reasonable. In the event that any court determines that the
duration or the geographic scope, or both, are unreasonable and that such
provision is to that extent unenforceable, the Parties agree that the provision
shall remain in full force and effect for the greatest time period and in the
greatest area that would not render it unenforceable. The Parties intend that
this non-competition provision shall be deemed to be a series of separate
covenants, one for each and every county of each and every state of the United
States of America and each and every political subdivision of each and every
country outside the United States of America where this provision is intended to
be effective.

         9.2 Confidentiality. Seller recognizes that by reason of its ownership
of the Business it has acquired confidential information and trade secrets
concerning the operation of the Business, the use or disclosure of which could
cause Buyer or its affiliates or subsidiaries substantial loss and damages that
could not be readily calculated and for which no remedy at law would be
adequate. Accordingly, Seller covenants and agrees with Buyer that it will not,
and will cause its subsidiaries to not, at any time, except with the prior
written consent of Buyer, directly or indirectly, disclose any secret or
confidential information that it may learn or has learned by reason of its
relationship to or ownership of the Business, or use any such information in a
manner detrimental to the interests of Buyer. The term "confidential
information" includes, without limitation, information not previously disclosed
to the public or to the trade by Seller's management with respect to the
Business, facilities, methods, trade secrets and other intellectual property,
software, systems, procedures, operational policies, manuals, confidential
reports, product price lists, pricing and cost policies, customer lists,
financial information (including the revenues, costs, or profits associated with
the Business), business plans, prospects, or opportunities related to the
Business but shall exclude (i) any information already in the public domain,
(ii) information that becomes part of the public domain by publication or
otherwise, except by a breach of this Agreement, (iii) information that Seller
can establish by reasonable proof was received from a third party with a right
to disclose it; or (iv) information that Seller is obligated to disclose by law
or in legal proceedings; provided, however, that Seller shall provide prompt
notice of any need to make such disclosure and cooperate with the disclosing
party in obtaining available protective orders, if any, relating thereto.


                                      A-48
<PAGE>   80

         9.3 Damages. Because of the difficulty of measuring economic losses to
Buyer as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Buyer for which it
would have no other adequate remedy, Seller agrees that the foregoing covenant
may be enforced by Buyer in the event of breach by Seller or any of its
subsidiaries by injunctions and restraining orders.

         9.4 Reasonable Restraint. The parties agree that the foregoing
covenants in this Article 9 impose a reasonable restraint on Seller and its
subsidiaries in light of the activities and business of Buyer on the date of the
execution of this Agreement and the current plans of Buyer.

         9.5 Severability; Reformation. The covenants in this Article 9 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent that the
court deems reasonable, and the Agreement shall thereby be reformed.

         9.6 Independent Covenant. All of the covenants in this Article 9 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of Seller against
Buyer or any of its affiliates, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by Buyer of such
covenants. The parties expressly acknowledge that the terms and conditions of
this Article 9 are independent of the terms and conditions of any other
agreements. It is specifically agreed that the period of four (4) years stated
at the beginning of this Article 9 during which the agreements and covenants of
Seller made in this Article 9 shall be effective, shall be computed by excluding
from such computation any time during which Seller is found by a court of
competent jurisdiction to have been in violation of any provision of this
Article 9. The covenants contained in Article 9 shall not be affected by any
breach of any other provision hereof by any party hereto and shall have no
effect if the transactions contemplated by this Agreement are not consummated.

         9.7 Materiality. Seller hereby agrees that the covenants set forth in
this Article 9 are a material and substantial part of the transactions
contemplated by this Agreement, supported by adequate consideration.

10. GENERAL

         10.1 Termination.

                  (a) This Agreement may be terminated at any time prior to the

stockholders, solely:

                           (i) by mutual written consent of Buyer and Seller;

                           (ii) by Seller, on the one hand, or by Buyer, on the
other hand, if the Closing shall not have occurred on or before 5:00 p.m.
Washington, D.C. time on September 30, 2000 provided that the right to terminate
this Agreement under this Section 10.1(b) shall not be available to either party
whose misrepresentation, breach of warranty or failure to fulfill any


                                      A-49
<PAGE>   81

obligation under this Agreement has been the cause of, or resulted in, the
failure of the Closing to occur on or before such date; or

                           (iii) by Buyer if there has been a material breach by
Seller of the representations and warranties of Seller set forth in this
Agreement or a material breach of a covenant of Seller hereunder, in each case
which renders the conditions in Article 6 hereof incapable of being satisfied;
provided, however, that the right to terminate this Agreement pursuant to
Section 10.1(c) shall not be available to Buyer if Buyer, at such time, is in
material breach of any representation, warranty, covenant or agreement set forth
in this Agreement;

                           (iv) by Seller if there has been a material breach by
Buyer of the representations and warranties of Buyer set forth in Article 4 or a
material breach of a covenant of Buyer hereunder, in each case which renders the
conditions in Article 7 incapable of being satisfied; provided, however, that
the right to terminate this Agreement pursuant to Section 10.1(c) shall not be
available to Seller if Seller, at such time, is in material breach of any
representation, warranty, covenant or agreement set forth in this Agreement;

                           (v) by Seller, on the one hand, or by Buyer, on the
other hand, if there shall have issued a final non-appealable order of a federal
or state court of competent jurisdiction in effect restraining, enjoining, or
otherwise preventing consummation of this Agreement; or there shall be any
action taken, or any statute, rule regulation or order enacted, promulgated or
issued or deemed applicable to the transactions contemplated hereby by any
governmental entity which would make the consummation of this Agreement illegal;

                           (vi) by either Seller or Buyer if Seller shall have
not obtained the Seller Stockholders Approval or the approval of the
stockholders of Seller at the Seller's Stockholders Meeting; or

                           (vii) by Seller for the purposes of pursuing an
Acquisition Proposal as contemplated under Section 5.4 .

                  (b) If (i) this Agreement is terminated pursuant to Section
10.1(a)(vi), (ii) Seller's board of directors fails to approve this Agreement
and the transactions contemplated hereunder, (iii) Seller violates the
provisions of Section 5.4, (iv) the Sagaponack Entities fail to consent to this
Agreement and the transaction contemplated hereunder, or (v) this Agreement is
terminated pursuant to Section 10.1(a)(iii), then Seller shall within ten days
from the termination of this Agreement pay to Buyer a termination fee equal to
$1,000,000 in cash and the reasonable out-of-pocket expenses (not to exceed an
additional $75,000) incurred by Buyer in connection with this Agreement, which
shall be payable immediately upon termination of this Agreement. The agreement
contained in this 10.1(b) is an integral part of the Transactions and
constitutes liquidated damages in the event of the occurrence of the
circumstances specified in this Section 10.1(b) and not a penalty.

         10.2 Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 10.1, this Agreement shall forthwith become void,
and there shall be no liability or obligation on the part of any party hereto or
its officers, directors or shareholders. Notwithstanding the foregoing sentence,
(i) the provisions of this Section 10.2 and Sections 5.1(b) and 5.1(c) and the
other provisions of Article 10 (including without limitation brokers and



                                      A-50
<PAGE>   82

expenses), shall remain in full force and effect and survive any termination of
this Agreement; (ii) each party shall remain liable for any breach of this
Agreement prior to its termination; and (iii) in the event of termination of
this Agreement pursuant to Section 10.1(c) or (d), then notwithstanding the
provisions of Section 10.8, the breaching party, shall be liable to the other
party to the extent of the reasonable expenses incurred by such other party in
connection with this Agreement and the transactions contemplated hereby, as well
as any damages in accordance with applicable law.

         10.3 Headings. The Article and Section headings contained in this
Agreement are inserted for convenience only and shall not affect in any way the
meaning or interpretation of this Agreement.

         10.4 Successors and Assigns. This Agreement and the rights of the
parties hereunder may not be assigned without the prior written consent of each
of the other parties hereto, except that Buyer, without Seller's prior consent,
may assign its rights and obligations under this Agreement to any of its
affiliates which are directly or indirectly wholly-owned subsidiaries of Danaher
Corporation. This Agreement shall be binding upon and shall inure to the benefit
of the parties hereto and the successors and permitted assigns of each of the
parties hereto.

         10.5 Entire Agreement. This Agreement (which includes the Disclosure
Schedule and Exhibits hereto) sets forth the entire understanding of the parties
hereto with respect to the transactions contemplated hereby. It shall not be
amended or modified except by a written instrument duly executed by each of the
parties hereto. Any and all previous agreements and understandings between or
among the parties regarding the subject matter hereof, whether written or oral,
are superseded by this Agreement. The Disclosure Schedule and each of the
Exhibits to this Agreement is incorporated herein by this reference and
expressly made a part hereof.

         10.6 Counterparts. This Agreement may be executed in any number of
counterparts each of which when executed and delivered shall be deemed to be an
original and all of which counterparts taken together shall constitute but one
and the same instrument. This Agreement shall become binding when one or more
counterparts taken together shall have been executed and delivered (which
deliveries may be by telefax) by the parties.

         10.7 Expenses. Buyer has paid and will pay the fees, expenses and
disbursements of Buyer and its agents, representatives, accountants and counsel
incurred in connection with the subject matter of this Agreement, whether or not
the transactions contemplated hereby are consummated. Seller has paid and will
pay the fees, expenses and disbursements of Seller and its agents,
representatives, financial advisers, accountants and counsel incurred in
connection with the subject matter of this Agreement, whether or not the
transactions contemplated hereby are consummated.

         10.8 Specific Performance; Remedies. Each party hereto acknowledges
that the other parties will be irreparably harmed and that there will be no
adequate remedy at law for any violation by any of them of any of the covenants
or agreements contained in this Agreement, including without limitation, the
confidentiality obligations set forth in Sections 5.1(b) and 5.1 (c) and the
restrictive covenants set forth in Article 9. It is accordingly agreed that, in
addition to


                                      A-51

any other remedies which may be available upon the breach of any such covenants
or agreements, each party hereto shall have the right to obtain injunctive
relief to restrain a breach or threatened breach of, or otherwise to obtain
specific performance of, the other parties, covenants and agreements contained
in this Agreement.

         10.10 Governing Law. This Agreement shall be construed, performed and
enforced in accordance with, and governed by the laws of the State of Delaware,
without regard to principles of conflicts of laws. Each party to this Agreement
shall have the right to enforce specifically the terms and provisions of this
Agreement in any court of the United States located in the State of Delaware or
in Delaware state court, this being in addition to any other remedy to which
they are entitled at law or in equity or under this Agreement. In addition, each
of the parties hereto (i) consents to submit such party to the personal
jurisdiction of any Federal court located in the State of Delaware or any
Delaware state court in the event any dispute arises out of this Agreement or
any of the transactions contemplated hereby, (ii) agrees that such party will
not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court and (iii) agrees that such party will not
bring any action relating to this Agreement or any of the transactions
contemplated hereby in any court other than a court of the United States located
in the State of Delaware or a Delaware state court. It is further agreed that
any breaching or defaulting party hereunder shall pay to the other parties
hereto such out of pocket costs and expenses, including legal and accounting
fees, as are reasonably incurred in pursuit of such parties' remedies hereunder.

         10.11 Severability. If any provision of this Agreement or the
application thereof to any person or circumstances is held invalid or
unenforceable in any jurisdiction, the remainder hereof, and the application of
such provision to such person or circumstances in any other jurisdiction, shall

be severable.

         10.12 Absence of Third Party Beneficiary Rights. Except as otherwise
expressly set forth in this Agreement, no provision of this Agreement is
intended, nor will be interpreted, to provide or to create any third party
beneficiary rights or any other rights of any kind in any client, customer,
affiliate, shareholder, employee, partner of any party hereto or any other
person or entity.

         10.13 Mutual Drafting. This Agreement is the mutual product of the
parties hereto, and each provision hereof has been subject to the mutual
consultation, negotiation and agreement of each of the parties, and shall not be
construed for or against any party hereto. Each party to this Agreement
acknowledges and represents that it has been represented by its own legal
counsel in connection with the transactions contemplated by this Agreement, with
the opportunity to seek advice as to its legal rights from such counsel.

         10.14 Amendment; Waiver. This Agreement may be amended by the parties
hereto at any time prior to the Closing by execution of an instrument in writing
signed on behalf of each of the parties hereto. Any extension or waiver by any
party of any provision hereto shall be valid only if set forth in an instrument
in writing signed on behalf of such party. Any waiver by any party of any
condition or of a breach of any provision, term, covenant, representation or
warranty contained in this Agreement, in any one or more instances, shall not be
deemed to be nor construed as, a further or continuing waiver of any such
condition or of a breach of any other provision, term, covenant, representation
or warranty of this Agreement.

         10.15 Public Disclosure. Prior to the Closing Date, neither Buyer nor
Seller shall make any disclosure (whether or not in response to an inquiry) of
the subject matter of this Agreement


                                      A-53
<PAGE>   85

unless previously approved by the other party in writing; provided, however,
that either party may make any public disclosure it believes in good faith is
required by law or regulation or the applicable rules of a stock exchange (in
which case the disclosing party shall advise the other party and provide it with
a copy of the proposed disclosure prior to making the disclosure).

         10.16 Accounting Principles. Except as otherwise expressly provided in
this Agreement, all accounting terms used in this Agreement shall be
interpreted, and all financial statements to and certificates and reports as to
financial matters required to be delivered hereunder shall be prepared in
accordance with United States generally accepted accounting principles ("GAAP")
consistently applied.

         10.17 Further Assurances. At any time and from time to tune after the
Closing without further consideration, each Party shall execute and deliver such
other instruments of sale, transfer, conveyance and assignment and take such
action as the other party hereto may reasonably determine is necessary to
transfer, convey and assign to the Buyer, to evidence and confirm Buyer's rights
to, title in and ownership of, the Purchased Assets, and to carry out the
purpose and intent of this Agreement.

         10.18 Shareholder Lawsuit. The parties acknowledge that on June 8,
2000, Stourbridge Investments Limited, on behalf of itself and the other
shareholders of Seller, filed a lawsuit in the Superior Court of the State of
California in and for the County of Los Angeles, Case Number B-C231418, (the
"Lawsuit") in which Seller and Buyer, among others, were named as defendants and
which made allegations relating to or arising out of the transactions
contemplated by this Agreement. By a letter dated June 27, 2000 (a copy of which
is attached hereto as Exhibit E (the "Indemnity Letter")), Seller agreed to
fully indemnify, defend, pay and hold harmless Danaher Corporation ("Danaher"),
its affiliates, each of its subsidiaries, and each of their officers, directors,
employees, agents and representatives from and against any and all liabilities,
losses, costs, expenses (including costs of mailing, printing, copying and other
administrative expenses), fees (including attorneys' fees), damages, fines and
payments of any kind that any of such indemnified parties may suffer, pay, or
otherwise incur resulting from, arising out of, connecting with or in any way
relating to (i) the Lawsuit or (ii) any other lawsuit, action, proceeding, cause
of action or other claim of any kind made by any of the shareholders of Seller
against any of such indemnified parties. The parties agree that the promises and
covenants made by Seller in the Indemnity Letter are hereby incorporated into
this Agreement as if made herein and shall be in addition to and in no way in
derogation of any of the other indemnity provisions and obligations contained in
this Agreement.

12265 West Bayaud Avenue
Suite 300
Lakewood, Colorado 80228

To The Board of Directors:

Under an engagement letter dated June 9, 2000, USTMAN Technologies, Inc.
("USTX", or the "Company") retained H.C. Wainwright & Co., Inc. ("Wainwright")
to provide an opinion as to the fairness from a financial point of view of the
Purchase Price (as defined below) to be paid to USTX in connection with the
acquisition (the "Acquisition") of the assets of USTX by Danaher Corporation,
either directly or through a wholly-owned subsidiary ("DHR"), as set forth in
the Asset Purchase Agreement by and among Veeder-Root Service Company and USTMAN
Technologies, Inc. dated as of July 21, 2000 (the "Acquisition Agreement"). The
Acquisition Agreement provides for the purchase by DHR of substantially all of
USTX's assets and certain liabilities for $17.158 million in cash, with no
financing contingency (the "Purchase Price"). The Purchase Price is subject to
revision by the amount, if any, that USTX's closing balance sheet is in excess
of, or less than, its December 31, 1999 cash and debt-free net equity.

Wainwright was selected by USTX's board of directors to render an opinion as to
the fairness from a financial point of view of the Purchase Price to be paid to
USTX, based on Wainwright's qualifications, reputation and expertise, and
familiarity with USTX.

Wainwright has reviewed with USTX's Board of Directors, among other things,
assumptions made, procedures followed, matters considered and limitations on the
scope of review undertaken by Wainwright in the course of rendering its opinion.
The opinion addresses the fairness to USTX of the aggregate consideration to be
paid to USTX by DHR for the assets and certain liabilities of USTX, from a
financial point of view, as of the date of the Wainwright opinion, and does not
constitute a recommendation to any stockholder.

In arriving at its opinion, Wainwright reviewed certain publicly available
business and financial information relating to USTX, including the exchange, at
the request of the management of USTX, of Sagaponack Partners, L.P.'s $7,000,000
in Senior Subordinated Notes and $2,717,000 in accrued interest, for $15,000,000
of Series A Preferred Stock in December 1998, as well as the Acquisition
Agreement. Wainwright also reviewed certain other information, including
financial forecasts, provided to it by USTX, and discussed the business, both
past and current, and future prospects of USTX. Wainwright also considered
certain financial and stock market data of USTX, and Wainwright compared that
data with similar data for other publicly held companies in businesses
Wainwright deemed similar to those of USTX. Wainwright considered the financial
terms, to the extent publicly available, of certain other recent business
combinations and other transactions, which have recently been effected, and that
Wainwright deemed relevant. Wainwright also considered such other information,
financial studies, analyses and investigations and financial, economic and
market criteria, which it deemed relevant. In connection with its review,
Wainwright did not assume any responsibility for independent verification of any
of the foregoing information and relied on the completeness and accurateness in
all material respects as represented by USTX . With respect to financial
forecasts, Wainwright assumed that they had been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
management of USTX as to the future financial performance of USTX. In addition,
Wainwright did not make an independent evaluation or appraisal of the assets or
liabilities

(contingent or otherwise) of USTX, nor was Wainwright furnished with any such
evaluations or appraisals. The Wainwright opinion is necessarily based upon
financial, economic, market and other conditions as they existed and could be
evaluated as of the date of the Wainwright opinion. Wainwright did not express
any opinion as to the prices that USTX and DHR common stock will trade
subsequent to the Acquisition.

We have assumed that the Purchase Price was determined by arm's-length
negotiation between the parties. In preparing the Wainwright opinion, Wainwright
performed a variety of financial and comparative analyses. The preparation of a
fairness opinion is a complex process and is not necessarily susceptible to
partial analysis or summary description. Wainwright believes that its analyses
must be considered as a whole and that selecting portions of its analyses and of
the factors considered by it, without considering all analyses and factors,
could create a misleading view of the process underlying the Wainwright opinion.
No company or transaction used in the analysis performed by Wainwright as a
comparison is identical to USTX. In addition, Wainwright may have given various
analyses more or less weight than other analyses, and may have deemed various
assumptions more or less probable than other assumptions, so that the range of
valuation resulting from any particular analysis undertaken should not be taken
to be Wainwright's view of the actual value of, USTX, . In performing its
analyses, Wainwright made numerous assumptions with respect to industry
performance and general business and economic conditions and other matters, many
of which are beyond the control of USTX. The analyses performed by Wainwright
are not necessarily indicative of actual values or actual future results, which
may be significantly more or less favorable than suggested by such analyses. In
addition, analyses relating to the value of businesses or assets do not purport
to be appraisals or to necessarily reflect the prices at which businesses or
assets may actually be sold. The analyses performed were prepared solely as part
of Wainwright's analysis of the fairness of the aggregate consideration and the
applicable purchase price to USTX from a financial point of view and were
provided to the USTX board of directors in connection with the delivery of the
Wainwright opinion.

Wainwright has rendered an opinion to USTX in connection with the proposed
Acquisition outlined herein, and will receive a fee for our services.

In the ordinary course of our business, Wainwright may have actively traded the
equity securities of the USTX or DHR and may continue to actively trade the
equity securities of USTX or DHR. In addition, certain individuals who are
employees or are affiliated with Wainwright have in the past and may currently
be shareholders of USTX.

Based upon and subject to the foregoing, it is Wainwright's opinion that, as of
the date hereof, the Purchase Price, for substantially all of the assets and
certain liabilities of USTX is fair, from a financial point of view to USTX.

We understand that you will include this opinion in its entirety as part of the
information you will distribute to the stockholders of USTX and file with the
Securities and Exchange Commission. We hereby consent to such distribution and
filing.

Very truly yours,
H.C. WAINWRIGHT & CO., INC

                       PLAN OF LIQUIDATION AND DISSOLUTION
                                       OF
                            USTMAN TECHNOLOGIES, INC.

         This Plan of Liquidation and Dissolution (the "Plan") is for the
purpose of effecting the complete liquidation and dissolution of USTMAN
Technologies, Inc., a California corporation (the "Company"), in accordance with
and pursuant to the applicable provisions of the California General Corporation
Law and Section 331 of the Internal Revenue Code of 1986, as amended, in
substantially the following manner:

         1.       EFFECTIVE DATE.

         The Plan shall be effective on the date (the "Effective Date"), after
it is adopted and approved by the affirmative vote of the holders of a majority
of the outstanding shares of Common Stock, no par value, of the Company ("Common
Stock") entitled to vote thereon, and subsequent to the closing of the sale of
the Company's business and substantially all of its assets pursuant to that
certain Asset Purchase Agreement dated July 21, 2000 (the "Asset Purchase
Agreement") by and among the Company and Veeder-Root Service Company.

         2.       CESSATION OF BUSINESS.

         After the Effective Date, the Company shall not engage in any business
activities except for the purposes of (i) preserving the values of its assets,
(ii) winding up its business affairs, including without limitation, the
consummation of a sale or sales in one or a series of transactions of the
remaining assets of the Company, and (iii) making the Liquidation Distribution
(as hereinafter defined) in accordance with the Plan. The Board of Directors of
the Company (the "Board") and, at their pleasure, the officers, shall continue
in office solely for these purposes.

         3.       DISSOLUTION.

         As promptly as practicable after the Effective Date, after winding up
the affairs of the Company and upon filing the Certificate of Election to Wind
Up and Dissolve and a Certificate Dissolution with the Secretary of State of the
State of California, the Company shall be dissolved in accordance with the
California General Corporation Law.

         4.       LIQUIDATION OF ASSETS.

         Commencing upon the Effective Date, the Company shall collect, sell,
exchange or otherwise dispose of all of its property and assets in one or more
transactions, including the property received pursuant to the consummation of
the Asset Purchase Agreement, upon such terms and conditions and for such
consideration, which may consist in whole or in part of money or other property,
as the Board deems expedient and in the best interests of the Company and the
holders of the Company's Series A Preferred Stock (the "Preferred Stockholders")
and Common Stock (the "Common Stockholders"). The Preferred Stockholders and the
Common Stockholders are sometimes hereinafter referred to as the "Stockholders".
In connection with such collection, sale, exchange and other disposition, the
Company shall marshal its assets and



                                      C-1
<PAGE>   91


collect or make provision for the collection of all accounts receivable, debts
and claims owing to the Company. The Company shall have continuing authority to
sell, lease exchange or otherwise convert to cash all or any part of its assets
in accordance with the terms and provisions of this Plan, and to make such
arrangements with respect to employee compensation as may be advisable.

         5.       PAYMENT OF DEBTS.

         The Company shall pay or make provision for the payment of all known or
ascertainable liabilities of and claims upon the Company, including all amounts
estimated by the Board to be necessary for the payment of estimated expenses,
taxes, and contingent liabilities (including expenses of dissolution,
liquidation, and termination of existence, and the Liquidation Distribution),
all as provided pursuant to Section [1905] of the California General Corporation
Law.

         6.       LIQUIDATING DISTRIBUTION.

         The Company shall distribute (i) first, pro rata to the Preferred
Stockholders, all its remaining property and assets, if any, including the
proceeds of any sale, exchange or disposition, except such property or assets as
are required for paying or making provision for the claims and obligations of
the Company in an amount equal to the aggregate amount of the liquidation
preference of the Preferred Stock as of the Record Date, as such liquidation
preference is determined in accordance with the Certificate of Determination of
Rights and Preferences of Preferred Shares as filed with the Secretary of State
of the State of California, and then, if there are any assets remaining after
all such distributions to Preferred Stockholders, (ii) pro rata to the Common
Stockholders (the "Liquidating Distribution"). The Liquidating Distribution may
occur all at one time or in a series of distributions and may be in cash or in
kind, in such manner, and at such time or times before and/or after the Record
Date (as defined below), as the Board, in its absolute discretion, may
determine. If and to the extent deemed necessary, appropriate or desirable by
the Board, in its absolute discretion, the Company may establish and set aside a
reasonable amount (the "Contingency Reserve") to satisfy claims against the
Company and all expenses of the sales of the Company's property and assets, of
the collection and defense of the Company's property and assets, and of the
liquidation and dissolution provided for in this Plan. The Contingency Reserve
may consist of cash or property.

         7.       REDEMPTION AND CANCELLATION OF PREFERRED STOCK AND COMMON
                  STOCK.

         The Liquidating Distribution shall be in complete redemption and
cancellation of all of the outstanding Preferred Stock and Common Stock of the
Company. The Company shall close its stock transfer books at the close of
business on the record date fixed by the Board for the first or any subsequent
installment of any Liquidating Distribution as the Board in its absolute
discretion may determine (the "Record Date"), and thereafter certificates
representing Preferred Stock and Common Stock shall not be assignable or
transferable on the books of the Company except by will, in testate succession
or operation of law. The Preferred Stockholders and Common Stockholders shall
surrender stock certificates (or, if so required by the Board in its absolute
discretion, furnish indemnity bonds in case of lost or destroyed certificates)
as a



                                      C-2
<PAGE>   92


condition to their receipt of any Liquidating Distribution immediately following
the Record Date.

         8.       MISSING STOCKHOLDERS.

         If any Liquidating Distribution to a Stockholder cannot be made,
whether because the Stockholder cannot be located, has not surrendered a
certificate evidencing their shares of Preferred Stock or Common Stock as
required hereunder or for any other reason, then the distribution to which such
Stockholder is entitled shall (unless transferred to the Trust established
pursuant to Section 11 hereof) be transferred to and deposited with the state
official authorized by the laws of the State of California to receive the
proceeds of such distribution; such transfer shall comply in all respects with
the laws of the State of California. The proceeds of such distribution shall
thereafter be held solely for the benefit of and for the ultimate distribution
to such Stockholder as the sole equitable owner thereof and shall escheat to the
State of California or be treated as abandoned property in accordance with the
laws of the State of California. In no event shall the proceeds of any such
distribution revert to or become the property of the Company.

         9.       REVOCATION.

         Notwithstanding adoption of the Plan by the Company's Common
Stockholders, Common Stockholders representing a majority of the issued and
outstanding voting interests in the Company may revoke the Plan to the extent
permitted by California law.

         10.      INDEMNIFICATION.

         The Company shall continue to indemnify its offices, directors,
employees and agents in accordance with its Certificate of Incorporation and
Bylaws and any contractual arrangements for actions taken in connection with
this Plan and the winding up of the affairs of the Company and shall indemnify
any liquidating trustees and their agents on similar terms. The Company's
obligations to indemnify such persons may be satisfied out of the assets of the
Trust (as defined below). The Board and the trustees, in their absolute
discretion, are authorized to obtain and maintain insurance for the benefit of
such officers, directors, employees, agents and trustees to the extent permitted
by law.

         11.      LIQUIDATING TRUST.

         If necessary for any reason to complete the liquidation and
distribution of the Company's assets to the Stockholders, the Board may at any
time transfer to a liquidating trust (the "Trust") any remaining assets of the
Company which are held as a reserve for contingent liabilities. The Trust, if
any, will succeed to all of the then remaining assets of the Company, including
such reserve, and any liabilities of the Company. The sole purpose of the Trust
will be to liquidate on terms satisfactory to the liquidating trustee(s) and to
distribute the assets formerly owned by the Company, if any, after paying any
remaining liabilities of the Company to the Stockholders.

         The Board is authorized to appoint one or more individuals or corporate
persons to act as trustee or trustees of the Trust and to cause to enter into a
liquidating trust agreement with such trustee or trustees on such terms and
conditions as the Board determines. Adoption of the Plan



                                      C-3
<PAGE>   93


will constitute the approval of the Stockholders of any such appointment and
liquidating trust agreement.

         12.      COSTS.

         The Board is authorized, empowered and directed to pay all legal,
accounting, printing, appraisal and other fees and expenses of persons rendering
services to the Company in connection with the sale of its assets, the Plan and,
if appointed, such expenses of a liquidating trustee or trustees.

         13.      AUTHORIZATION.

         Adoption of the Plan by the Stockholders shall constitute full and
complete authority to the proper officers of the Company, without further
Stockholder action (except for any further Stockholder or Board approval
required by law), to do and perform any and all acts and to make, execute and
deliver any and all agreements, conveyances, assignments, transfers,
certificates and other documents of every kind and character which such officers
deem necessary or appropriate to carry out the provisions of the Plan.

         14.      POWER OF THE BOARD OF DIRECTORS.

         The Board and, if authorized by the Board, the officers, shall have
authority to do or authorize any and all acts and things as provided for in the
Plan and any and all such further acts and things as they may consider desirable
to carry out the purpose of the Plan, including the execution and filing of all
other documents which may be necessary or appropriate to implement the Plan. The
Board, to the extent permitted by law, may authorize such variations from or
amendments to the provisions of the Plan as may be necessary or appropriate to
effectuate the complete liquidation and dissolution of the Company, and the
distribution of its assets, if any, to its Stockholders in accordance with the
California General Corporation Law. The death, resignation, or other disability
of any director or officer of the Company shall not impair the authority of the
surviving or remaining director(s) or officer(s) to exercise any of the powers
provided for in the Plan. Upon such death, resignation, or other disability, the
surviving or remaining directors, or if there be none, to the extent permitted
by law, the surviving or remaining officer(s) shall have authority to fill the
vacancy or vacancies so created, but the failure to fill such vacancy or
vacancies shall not impair the authority of the surviving or remaining
director(s) or officer(s) to exercise any of the powers provided for in the
Plan. In connection with and for the purpose of implementing and assuring
completion of this Plan, the Company may, in the absolute discretion of the
Board, pay to the Company's officers, directors and employees, or any of them,
compensation or additional compensation above their regular compensation, in
money or other property, in recognition of the extraordinary efforts they, or
any of them, will be required to undertake, or actually undertake, in connection
with the successful implementation of this Plan. Adoption shall constitute the
approval of the Stockholders of the payment of any such compensation.

                                    GUARANTY

         THIS GUARANTY ("Guaranty") is made jointly and severally as of July 21,
2000, by Sagaponack Partners, L.P., a Delaware limited partnership having a

Islands exempted limited partnership having a principal business address of c/o
Citco Trust, P.O. Box 31106 SMB Corporate Center Windward One, West Bay Road,
Grand Cayman, Cayman Islands ("Sagaponack II") (collectively the two Sagaponack
entities being the "Guarantors"), in favor of Veeder Root Service Company, a
Delaware corporation ("Veeder"), and its officers, directors, employees,
stockholder, assigns, successors and affiliated companies, including without
limitation Danaher Corporation, a Delaware corporation (collectively with
Veeder, the "Indemnified Parties"). Capitalized terms not defined herein shall

Preferred Stock of Ustman, which Series A Preferred Stock had an allocation
amount for purposes of liquidation priority and dividends of $17,230,285 as of
March 31, 2000.

B. Pursuant to an Asset Purchase Agreement of even date herewith (the "Purchase
Agreement"), Ustman intends to sell and Veeder intends to purchase substantially
all of the assets of Ustman for $17,350,000.

C. Guarantors will be directly and materially benefited by the consummation of
the transactions contemplated by the Purchase Agreement.

D. As a condition to Veeder's obligation to consummate the transactions
contemplated by the Purchase Agreement, Guarantors are required to execute and
deliver this Guaranty.

E. In order to induce Veeder to consummate the transactions contemplated by the
Purchase Agreement, Guarantors agree to jointly and severally execute and
deliver this Guaranty on the terms and conditions contained herein.

         NOW THEREFORE, in consideration of the premises, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, Guarantors hereby covenant and
agree with the Indemnified Parties as follows:

         1. If Ustman shall default in the payment when due of any amount due to
any of the Indemnified Parties under Article 8 of the Purchase Agreement, and no
funds under the Holdback are available to make such payment, Guarantors, jointly
and severally, shall forthwith on demand by Veeder unconditionally pay to Veeder
on behalf of the Indemnified Party in



                                      D-1
<PAGE>   95

immediately available funds by wire transfer to an account identified by Veeder
an amount equal to the amount payable by Ustman up to an aggregate maximum of
One Million Five Hundred Thousand and 00/100 U.S. Dollars ($1,500,000.00);
provided however that from and after April 1, 2002, the maximum aggregate
obligation of the Guarantors hereunder shall not exceed one half of the
previously unused portion of the guaranty obligation of Guarantors under this
Guaranty. Guarantors agree to make such full payment irrespective or whether or
not any one or more of the following events occurred: (i) an Indemnified Party
has made any demand on any obligor (other than Ustman) or guarantor of any of
the obligations of Ustman under the Purchase Agreement; (ii) an Indemnified
Party has taken any action of any nature against Ustman or any other obligor or
guarantor of any of the obligations of Ustman under the Purchase Agreement;
(iii) an Indemnified Party has pursued any rights which it has against any other
person or entity who may be liable for the obligations of Ustman under the
Purchase Agreement; or (iv) an Indemnified Party holds or has resorted to any
security for the obligations of Ustman under the Purchase Agreement (except to
the Holdback).

         2. Guarantors shall not be exonerated or discharged nor shall their
liability be affected by any forbearance, whether as to payment, time,
performance or otherwise howsoever, or by any other indulgence being given to
Ustman or by any variation of the terms of the Purchase Agreement or by any act,
thing, omission or means whatsoever which, but for this provision, might operate
to exonerate or discharge Guarantors from their obligations under the this
Guaranty.

the transactions contemplated thereby, Guarantors jointly and severally make the
following representations and warranties to Veeder:

complete and correct copies of (A) such Guarantor's audited consolidated balance

balance sheets, statements of income and cash flow for the three month period
ended March 31, 2000 (the items in the foregoing (A) and (B) being collectively,
the "Guarantors Financial Statements"). The Guarantors Financial Statements
(including the notes thereto) have been prepared in accordance with GAAP
consistently applied, and fairly present the financial condition of each
Guarantor, as applicable. Since the dates of the Guarantors Financial
Statements, there have been no material changes in Guarantor's accounting
policies;

                  (e) (i) no other agreement, representation or special
condition exists between any Guarantor and Ustman regarding the liability of any
Guarantor hereunder, nor does any understanding exist between any Guarantor and
Ustman that the obligations of Guarantors hereunder are or will be other than as
set forth herein; and (ii) as of the date hereof, Guarantors have no defense
whatsoever to any action or proceeding that may be brought to enforce this
Guaranty.

Guarantor have been timely filed and payment has been made or will have been
made prior to the date upon which any penalty or fine may be imposed; all taxes
which have or may become due pursuant to said returns or pursuant to assessments
received have been paid, except to the extent that such taxes



                                      D-3
<PAGE>   97

are being contested in good faith by appropriate proceedings diligently
conducted and for which such reserves or other appropriate provisions, if any,
as shall be required by generally accepted accounting principles ("GAAP") shall
have been made; and

                  (g) each Guarantor is solvent as of the date hereof; and after
giving effect to the transactions contemplated by this Guaranty, Guarantor will
be solvent.

Agreement which are guaranteed hereunder expire or are satisfied in full,
Guarantors waive and agree not to enforce any claim, right or remedy of any kind
that Guarantors may now have or hereafter acquire against any Indemnified Party,
whether or not any such claim, right or remedy arises in equity, under contract,
by statute or otherwise. Guarantors acknowledge that they will receive direct
and indirect benefits from the transactions contemplated by the Purchase
Agreement and that the waivers set forth in this Paragraph are knowingly made in
contemplation of such benefits.

         5. Guarantors waive promptness and diligence by the Indemnified Parties
with respect to their respective right under the Purchase Agreement and the
Ancillary Documents, including without limitation, this Guaranty.

         6. Guarantors waive any and all notice with respect to: (i) the

any default in connection with the obligations of Ustman under the Purchase
Agreement.

         7. Guarantors waive any rights of presentment, demand, notice of
dishonor or nonpayment, protest and notice of protest in connection with the

         8. Guarantors agree that the Indemnified Parties may from time to time,
whether before or after the occurrence of any breach of any obligation under the
Purchase Agreement, and as many times as the Indemnified Parties, in their sole
discretion, deem appropriate, do any of the following without notice to
Guarantors and without adversely affecting the validity or enforceability of
this Guaranty: (i) release, surrender, exchange, compromise, or settle any claim
for indemnification or breach of any obligation under the Purchase Agreement;
(ii) change, renew or waive the terms of the Purchase Agreement; (iii) grant any
extension or indulgence with respect to the payment or performance of any
obligation under the Purchase Agreement or any of the Ancillary Documents; (iv)
enter into any agreement or forbearance with respect to any claim for
indemnification or breach of any obligation under the Purchase Agreement; or (v)
sell, release, surrender, exchange or compromise any security held by the

Agreement; provided, however, that notwithstanding the foregoing, the
Indemnified Parties may not waive or release the primary obligation of Ustman as
indemnitor under the Purchase Agreement nor waive or release the Indemnified
Parties recourse to the Holdback under the Purchase Agreement for payout of any
indemnity obligation. Guarantors agree that the Indemnified Parties may do any
of the above, and upon such terms and conditions, as the Indemnified Parties

will remain liable for full payment of Ustman's indemnification obligations
guaranteed hereunder.

         9. This Guaranty shall be a continuing guaranty and indemnity and shall

Ustman arising, and all monies owing or payable by Ustman in respect of
indemnification obligations, under the Purchase Agreement have been paid,
discharged or satisfied in full or have expired and notwithstanding any
insolvency of Ustman as the case may be or any change in the status of Ustman.

2003 except as to indemnification claims raised by an Indemnified Party under
the Purchase Agreement prior to April 1, 2003.

         10. Guarantors agree that no failure or delay on the part of the
Indemnified Parties to exercise any of their rights, powers or privileges under
this Guaranty shall be a waiver if such rights, powers or privileges or a waiver
of any default, nor shall any single or partial exercise of any of the
Indemnified Parties' rights, powers or privileges preclude other or further
exercise thereof or the exercise of any other right, power or privileges or be
construed as a waiver of any default. Guarantors further agree that no waiver or
modification of any rights of the Indemnified Parties under this Guaranty shall
be effective unless in writing and signed by Veeder. Guarantors further agree
that each written waiver shall extend only to the specific instance actually

faith and by appropriate and lawful proceedings diligently conducted and for
which such reserve or other appropriate provisions, if any, as shall be required
by GAAP shall have been made;

                  (c) neither Guarantor shall sell, transfer or assign any
material part of its assets unless such assets so sold, transferred or assigned
are replaced with assets of equal or greater value (it being understood that
neither Guarantor shall be prohibited from making

combination of both) and it shall not liquidate, dissolve, consolidate or merge

                  (d) each Guarantor shall insure its properties and assets

         16. Guarantors agree that this Guaranty shall be binding upon
Guarantors, their successors and assigns, provided, however, that Guarantors may
not assign or transfer any of Guarantors' rights and obligations hereunder or
