Item 2.  Acquisition or Disposition of Assets
         ------------------------------------

     Pursuant to an Agreement and Plan of Reorganization dated as of November
16, 1999 (the "Agreement") among Tut Systems, Inc., a Delaware corporation
("Tut"), Fortress Acquisition Corporation, a Delaware corporation and a wholly
owned subsidiary of Tut ("Sub"), FreeGate Corporation ("FreeGate"), U.S. Bank
Trust, as Escrow Agent and, with respect to Article VII only, James Mongiello,
as Stockholder Representative, on February 14, 2000 (the "Closing"), Tut
acquired FreeGate by means of a merger of FreeGate with and into Sub (the
"Merger").  As a result of the Merger, each share of FreeGate capital stock was
converted into shares of Tut Common Stock according to the following exchange
ratios: 0.017617 shares of Tut Common Stock for each share of FreeGate common
stock, 0.001516 shares of Tut Common Stock for each share of Series A Preferred
Stock, 0.009476 shares of Tut Common Stock for each share of Series B Preferred
Stock, 0.021478 shares of Tut Common Stock for each share of Series C Preferred
Stock,  0.037903 shares of Tut Common Stock for each share of Series D Preferred
Stock. All options and warrants to purchase shares of FreeGate capital stock
were cancelled upon the Closing.  The Company issued options to purchase Tut
Common Stock in substitution for 1,113,000 cancelled options at an exchange
ratio of 0.017617 shares of Tut Common Stock for each one share of FreeGate
common stock subject to those options.  At the Closing, ten percent of the
shares issued pursuant to the Merger were deposited into an escrow account to
secure the indemnification obligations of FreeGate (the "Escrow Fund").  The
Escrow fund is to be governed by the terms set forth in the Agreement at Tut's
cost and expense.  The Escrow Fund shall be the sole source of funds available
for the fulfillment of any indemnification obligations of FreeGate to Tut and
Sub.

     The provisions of the Agreement described in this report are qualified in
their entirety by reference to the actual text of that agreement, included as an
exhibit to this report.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors of
FreeGate Corporation

  In our opinion, the accompanying balance sheet as of December 31, 1999 and
the related statements of operations, of cash flows, and of stockholders'
equity (deficit) present fairly, in all material respects, the financial
position of FreeGate Corporation at December 31, 1999, and the results of its
operations and its cash flows for the year then ended in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for the opinion expressed above.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors of
FreeGate Corporation

  We have audited the accompanying balance sheet of FreeGate Corporation (the
"Company") as of December 31, 1998, and the related statements of operations,
stockholders' equity, and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of FreeGate Corporation as of
December 31, 1998, and the results of its operations and its cash flows for the
year then ended, in conformity with generally accepted accounting principles.

  The accompanying financial statements have been prepared assuming the Company
will continue as a going concern. As discussed in Note 1 to the financial
statements, the Company has incurred net losses and negative operating cash
flows since inception that cause substantial doubt about its ability to
continue as a going concern. Management's plans in regard to these matters are
also described in Note 1. Continuation of the Company as a going concern is
dependent upon management's ability to obtain additional financing and the
successful development and marketing of its products. The financial statements
do not include any adjustments that might result from the outcome of this
uncertainty.


                                                                    /s/ KPMG LLP

                         NOTES TO FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 (a) Description of business

  FreeGate Corporation (the "Company") was incorporated in the state of
Delaware on December 26, 1995. FreeGate Corporation provides "all-in-one"
Internet and Intranet connectivity solutions for small to medium sized
businesses and branch offices. These solutions combine E-mail, web access and
publishing, electronic file transfer, remote access, virtual private
networking, firewall security, and LAN/router capabilities in an affordable,
reliable turnkey system for a nontechnical audience.

  Beyond this integrated Internet and Intranet functionality, the Company
provides a remote provisioning and management system that opens up business
opportunities for value-added Internet applications and services, with
increased security and reliability.

 (b) Basis of presentation

  The Company has incurred net losses and negative operating cash flows since
inception that raise substantial doubt about its ability to continue as a going
concern. The accompanying financial statements have been prepared assuming the
Company continues in existence as a going concern. Continuation of the Company
as a going concern is dependent upon the successful conclusion of the merger
agreement signed in November 1999 (see Note 7).

 (c) Use of estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
reported results of operations during the reporting period. Actual results
could differ from those estimates.

 (d) Revenue recognition

  On October 1, 1997, the Company adopted Statement of Position (SOP) 97-2,
Software Revenue Recognition. The adoption of SOP 97-2 did not have a material
effect on the Company's operating results. SOP 97-2 generally requires revenue
earned on software arrangements involving multiple elements to be allocated to
each element based on the relative fair values of the elements. The fair value
of an element must be based on evidence that is specific to the vendor. If a
vendor does not have evidence of the fair value of all elements in a multiple-
element arrangement, all revenue from the arrangement is deferred until such
evidence exists or until all elements are delivered.

  Product revenue is generally recognized upon delivery or if sales are made to
a distributor, with right of return, upon sell through, provided the Company
deems the receivable to be collectible. Revenue allocated to maintenance is
recognized ratably over the maintenance term.

 (e) Concentrations of credit risk

  Financial instruments that subject the Company to concentrations of credit
risk consist primarily of cash and cash equivalents, accounts receivable, and a
note receivable. The Company maintains all of its cash with one financial
institution in the United States. Cash equivalents are comprised of money
market funds. The Company's policy limits the amount of credit exposure in any
one-debt issue. Management believes the financial risks associated with these
financial instruments are minimal. The notes receivable are due from
stockholders of the Company and management believes that the risk of credit
loss is low. With respect to accounts receivable, the Company performs credit
evaluations of its customers and maintains reserves for potential credit
losses.

 (f) Capitalized software

  Costs related to the research and development for new software products and
enhancements to existing software products are expensed as incurred until
technological feasibility of the product has been established, at which time
such costs are capitalized subject to expected recoverability. As of December
31, 1999, the Company had not capitalized any development costs related to
software products.

 (g) Inventory

  Inventory as of December 31, 1999, consisted of finished goods and raw
materials valued at the lower of cost, using the first in first out method, or
market.

 (h) Property and equipment

  Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is calculated using the straight-line method over
the estimated useful lives of the equipment, generally three years. Assets
under capital leases are amortized over the shorter of the lease terms or the
estimated useful lives of the assets.

 (i) Income taxes

  The Company utilizes the asset and liability method of accounting for income
taxes. Under the asset and liability method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases and operating loss and tax
credit carryforwards. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. A
valuation allowance is recorded to reduce deferred tax assets to an amount that
is more likely than not to be realized. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date.

 (j) Stock-based compensation

  The Company accounts for its employee stock option plan in accordance with
the provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting
for Stock Issued to Employees, and related interpretations. As such,
compensation expense is recorded on the date of grant only if the current
market price of the underlying stock exceeds the exercise price. Statement of
Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based
Compensation, permits entities to recognize as expense over the vesting period
the fair value of all stock-based awards on the date of grant. Alternatively,
SFAS No. 123 allows entities to continue to apply the provisions of APB Opinion
No. 25 and provide pro forma net income or loss disclosures for employee
options granted as if the fair value-based method defined in SFAS No. 123 had
been applied. The Company has elected to apply the provisions of APB Opinion
No. 25 and provide the pro forma disclosure provisions of SFAS No. 123.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 (k) Accumulated other comprehensive income

  In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
130, Reporting Comprehensive Income. SFAS No. 130 establishes standards of
reporting and display of comprehensive income and its components of net income
and "Other Comprehensive Income" in a full set of general-purpose financial
statements. Other comprehensive income refers to revenues, expenses, gains, and
losses that are not included in net income but rather are recorded directly in
stockholders' equity. SFAS No. 130 was adopted by the Company in 1998 but the
Company has no elements of other comprehensive income.

 (l) Impairment of long-lived assets

  In accordance with SFAS No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of, management evaluates the
Company's long-lived assets for impairment whenever events or changes in
circumstances indicate that the carrying value of an asset may not be
recoverable. As of December 31, 1999, the Company does not consider any assets
to be impaired.

 (m) Net loss per share

  Basic net loss per share is computed using the weighted-average number of
vested outstanding shares of common stock. Diluted net loss per share is
computed using the weighted-average number of shares of vested common stock
outstanding and when dilutive, unvested common stock outstanding, potential
common shares from options and warrants to purchase common and preferred stock
using the treasury stock method and from convertible securities using the as-
if-converted basis. All potential common shares have been excluded from the
computation of diluted net loss per share for all periods presented because the
effect would be antidilutive.

  Diluted net loss per share does not include the effect of the following (in
thousands):

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

Shares of convertible preferred stock on an "as-if-converted"
 basis........................................................  16,715  16,715
</TABLE>

  The weighted-average exercise price of stock options outstanding was $0.24
and $0.53 as of December 31, 1998 and 1999, respectively. The weighted-average
purchase price of unvested stock was $0.11 and $0.41 as of December 31, 1998
and 1999, respectively. The weighted-average exercise price of warrants was
$1.14 and $2.61 as of December 31, 1998 and 1999, respectively.

 (n) Recent Accounting Pronouncements

  In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. FreeGate is required to adopt SFAS No. 133
in fiscal 2001. SFAS No. 133 establishes methods of accounting for derivative
financial instruments and hedging activities related to those instruments as

derivative financial instruments or hedging activities.

  In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements," which provides guidance on the recognition, presentation, and
disclosure of revenue in financial statements filed with the SEC. SAB 101

outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. Management
believes that the impact of SAB 101 will not have a material effect on the
financial position or results of the operations of the Company.

3. STOCKHOLDERS' EQUITY

 (a) Convertible preferred stock

  The rights, preferences, and privileges of the holders of Series A, B, C, and
D convertible preferred stock are as follows:

  . The holders of Series D convertible preferred stock shall be entitled to
    receive dividends, at a rate of $0.18 per share, per annum in preference
    to holders of Series A, B, and C convertible preferred stock payable when
    and if declared by the Company's Board of Directors. The holders of
    Series A, B, and C convertible preferred stock are entitled to receive
    dividends at the rate of $0.0075, $0.045, and $0.102, per share,
    respectively, per annum, payable when and if declared by the Company's
    Board of Directors in preference and priority to any payments of
    dividends to holders of the Company's common stock. The dividend rights
    are not cumulative.

  . The holders of Series D convertible preferred stock have a liquidation
    preference of $3.00 per share in preference to the holders of Series A,
    B, and C convertible preferred stock. Subject to Series D rights, the
    holders of Series A, B, and C convertible preferred stock have a
    liquidation preference of $0.12, $0.75, and $1.70 per share,
    respectively. After payment of the liquidation preference, all remaining
    assets of the Company shall be distributed among holders of convertible
    preferred stock and common stock pro rata on an "as-if-converted" basis.
    Distributions to holders of convertible preferred stock are limited to an
    aggregate of $0.24, $1.50, $3.40, and $6.00 per share to holders of
    Series A, B, C, and D convertible preferred stock, respectively. After
    payment of the maximum liquidation distribution to holders of convertible
    preferred stock, any remaining assets of the Company will be distributed
    pro rata to holders of common stock.

  . Each share of convertible preferred stock is convertible into one share
    of common stock. Conversion will occur automatically upon an initial
    public offering with a price of not less than $4.50 per share and
    proceeds in excess of $30,000,000.

  . Holders of Series A, B, C, and D convertible preferred stock vote equally
    with shares of common stock on an "as-if-converted" basis.

  . Holders of Series A, B, C, and D convertible preferred stock possess
    certain registration rights and the right to participate in future
    financings.

  No dividends have been declared or paid on convertible preferred stock or
common stock since inception of the Company.

 (b) Common stock

  During 1996, the Company issued 6,000,000 shares of common stock to the
Company's founders in exchange for certain rights and services. The fair value
assigned to the rights and services was equivalent to the fair value of the
common stock on the issuance date as determined by the Board of Directors. Upon
issuance, the Company had the right to repurchase 50% of these shares at $0.005
per share. Subject to continued employment of the founders, the repurchase
right expired in December 1996 for 25% of the shares and, for the remaining
shares, expired ratably over 36 months through December 1999. Under certain
circumstances, the shares may immediately vest upon a change in control of the
Company.

  Stock issued to the founders, as well as stock issued upon exercise of stock
options under the 1996 Stock Option Plan, is subject to vesting. The Company
reserves the right of first refusal to purchase all vested shares of common
stock. All unvested shares of common stock may be repurchased by the Company at
the original issuance price upon an employee's termination of employment. The
repurchase right expires when the Company's stock becomes publicly traded or
upon a change in control of the Company. As of December 31, 1998 and 1999,
2,017,832 and 2,579,419 shares of outstanding common stock, respectively, are
unvested and, therefore, subject to repurchase by the Company.

                              FREEGATE CORPORATION

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


  By decision of the Board of Directors in November 1999, however, these
options will vest immediately on the closing date of the merger of the Company.

 (c) 1996 Stock Option Plan

  The Company's 1996 Stock Option Plan (the "Plan") authorizes the granting of
incentive and nonstatutory common stock options to employees and nonemployees
at exercise prices no less than 85% of the fair market value of the common
stock on the grant date, as determined by the Board of Directors. The options
may be exercised immediately upon issuance and generally have a term of 10
years. The common stock issued upon the exercise of stock options vests 25%
after one year of service and thereafter ratably over 36 months of service.
Upon termination of service, an employee's unvested shares may be repurchased
by the Company at the option exercise price. Approximately 5,000,000 shares of
common stock have been reserved for issuance under the Plan.

 (d) Accounting for stock-based compensation

  Under APB Opinion No. 25, the Company has recorded no compensation costs
related to its stock option plan for the year ended December 31, 1999, because
the exercise price of each employee option equals or exceeds the market value
of the underlying common stock as of the grant date for each employee stock
option. Had compensation cost for the Company's plans been determined
consistent with the fair value approach enumerated in SFAS No. 123, the
Company's pro forma net loss would have been as follows (in thousands, except
per share amounts):

</TABLE>

  The fair value of employee options granted was estimated on the date of grant
using the minimum-value method. The fair value of nonemployee options granted
was estimated on the date of grant using the Black-Scholes option-pricing
model. There were no nonemployee options granted in 1998. The following
weighted-average assumptions were used in these calculations: risk-free
interest rate of approximately 5.3% and 6.1% for the years ended 1998 and 1999,
respectively; expected life of five years and ten years for the years ended
December 31, 1998 and 1999, respectively; no dividends and expected volatility
of 0% and 65% for employee and nonemployee options, respectively.

  The weighted average fair values of options granted in 1998 and 1999 was
$0.07 and $0.24, respectively.

4. INCOME TAXES

  Income tax expense for the years ended December 31, 1998 and 1999, consisted
of state income tax. The difference between the statutory income tax rate of
34% and the Company's effective tax rate is primarily due to the valuation
allowance provided for deferred tax assets. The Company has provided a
valuation allowance due to the uncertainty of generating future taxable income
that would allow for the realization of such deferred tax assets.

  The types of temporary differences that give rise to significant portions of
the deferred tax assets and liabilities as of December 31, 1998 and 1999 are as
follows (in thousands):

</TABLE>

  The change in valuation allowance for the years ended December 31, 1998 and
1999, was $5,038,000 and $2,333,000 respectively.

  The Company has net operating loss carryforwards for federal and state tax
purposes of approximately $24,000,000 and $20,500,000, respectively. The
federal carryforwards expire from 2010 to 2018. The state net operating loss
carryforwards expire in 2003. The Company also has tax credit carryforwards of
approximately $591,000 and $366,000 for federal and state tax purposes,
respectively, which expire from 2001 to 2003.

  The Internal Revenue Code of 1986, and applicable state tax laws, impose
substantial restrictions on the ability of the Company to utilize net operating
loss and tax credit carryforwards in the event of an ownership change, as
defined. During 1997, the Company underwent an ownership change, and, as a
result, the federal and state tax losses and tax credit carryovers incurred
through that date are subject to an annual limitation.

5. COMMITMENTS AND CONTINGENCIES

 Lease Obligations

noncancelable operating leases. In addition, the Company has entered into

6. SEGMENT INFORMATION

  The Company has adopted the provisions of SFAS No. 131, Disclosure about
Segments of an Enterprise and Related Information. SFAS No. 131 establishes
standards for reporting information about operating segments. The method for
determining what information to report is based on the way that management
organizes the operating segments within the Company for making operating
decisions and assessing financial performance. The Company's chief operating
decision-maker is considered to be the Company's Chief Executive Officer (CEO).
The consolidated financial information reviewed by the CEO is identical to the
information presented in the accompanying statements of operations. Therefore,
the Company operates in a single operating segment.

  The CEO does not receive discrete financial information about individual
components of the Company's operations. The CEO reviews financial information
presented on a consolidated basis accompanied by disaggregated information
about revenue by geographic region for purposes of making operating decisions
and assessing financial performance.

ended December 31, 1998 and 1999 are as follows (in thousands):

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                                 (in thousands)

NOTE 1--BASIS OF PRESENTATION:

  The pro forma financial information gives effect to Tut's acquisition of
FreeGate, consummated on February 14, 2000 in a business combination to be
accounted for as a purchase. All the outstanding common and preferred stock of
FreeGate was converted into shares of Tut common stock, and all outstanding
stock options to purchase shares of FreeGate common shares and options to be
issued to FreeGate stockholders and options holders.

  The pro forma financial information has been prepared on the basis of
assumptions described in the following notes and include assumptions relating
to the allocation of the consideration paid for the assets and liabilities of
FreeGate based on preliminary estimates of their fair value. The actual
allocation of such consideration may differ from that reflected in the pro
forma financial statements after valuations after the closing of the FreeGate
acquisition have been completed. Tut does not expect that the final allocation
of the purchase price will differ materially from the preliminary allocation.

  The Unaudited Pro Forma Combined Statement of Operations for the year ended
December 31, 1999 gives effect to this transaction as if it had taken place on
January 1, 1999. The Unaudited Pro Forma Combined Balance Sheet as of December
31, 1999 gives effect to the transaction as if it had taken place on December
31, 1999.

  The pro forma financial information is not necessarily indicative of what the
actual financial results would have been had the transaction taken place on
January 1, 1999 and do not purport to indicative the results of future
operations.

NOTE 2--PURCHASE PRICE ALLOCATION:

  The unaudited pro forma combined information reflects a total purchase price
of $24.7 million from 510,931 shares of common stock, approximately 19,600
options to acquire common stock and acquisition related expenses, consisting
primarily of investment advisory, legal and other professional fees. The
Company valued the options using the Black-Scholes option pricing model,
applying an average expected life of 4 years, a weighted average risk free
rate of 6%, an expected dividend yield of zero percent, a volatility of 80%
and a deemed fair value of common stock of $41.81.

  The Company's allocation of aggregate purchase price to the tangible and
identifiable assets acquired in connection with this acquisition has been based
on a preliminary analysis by the Company and the goodwill, patents and current
technology are being amortized over an estimated useful life of five years and
assembled workforce is being amortized over an estimated useful life of three
years. The allocation is summarized below (in thousands):

    NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION--(Continued)
                                 (in thousands)

  The amount allocated to in-process research and development represents the
purchased in-process technology for projects that, as of the date of the
acquisition, had not yet reached technological feasibility and had no
alternative future use. Based on preliminary assessments, the value of these
projects was determined by using the income approach, which discounts expected
future cash flows to present value. The discount rate used in the present value
calculations were typically derived from a weighted average cost of capital
analysis adjusted upwards to reflect additional risks inherent in the
development life cycle. These risk factors are reflected in the discount rate
used of 30%. Tut expects that the pricing model for products and intellectual
property licenses related to the acquisition of FreeGate will be considered
standard within the high-technology communications industry. Tut does not
expect, however, to achieve expense reductions as a result of integrating the
acquired in-process technology. Therefore, the valuation assumptions do not
include any anticipated cost savings. Tut expects that products incorporating
the acquired technology from this acquisition will be completed and begin to
generate cash flows over a six to nine month period after integration.
Development of these technologies, however, remains a significant risk due to
the remaining effort to achieve technical viability, rapidly changing customer
markets, uncertain standards for new products and significant competitive
threats from numerous companies. Efforts to develop the acquired technology into
commercially viable products consists principally of planning, designing and
testing activities necessary to determine that the product can meet market
expectations, including functionality and technical requirements. Failure to
bring these products to market in a timely manner could result in a loss of
market share, or a lost opportunity to capitalize on emerging markets, and could
harm our business and operating results.

  The amounts allocated to in-process research and development will be charged
to the statement of operations in the period the acquisition is consummated.

NOTE 3--UNAUDITED PRO FORMA COMBINED NET LOSS PER SHARE:

  The net loss per share and shares used in computing the net loss per share
for the year ended December 31, 1999 are based upon the Tut historical weighted
average common shares outstanding together with the shares issued in the
transaction as if such shares were issued January 1, 1999. Common stock
issuable upon the exercise of Tut stock options and warrants has been excluded
as the effect would be anti-dilutive. In addition to the shares used in
computing the net loss per share above, pro forma net loss per share is
calculated using the convertible preferred stock outstanding as if such shares
were converted to common stock at the time of issuance or January 1, 1999 for
the stock issued in the transaction.

NOTE 4--PURCHASE ADJUSTMENTS:

  The following adjustments were applied to the combined financial statements:

  (A) To reflect the issuance of shares in the acquisition and to record
      estimated transaction costs and other assets and liabilities at their
      fair values.

  (B) To record amortization of goodwill and other intangibles.

  The amount allocated to in-process research and development has not been
included in the unaudited pro forma combined statement of operations as it is
nonrecurring. This amount will be expensed in the period the acquisition is
consummated.

                      AGREEMENT AND PLAN OF REORGANIZATION

     This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of November 16, 1999 among Tut Systems, Inc., a Delaware
corporation ("Parent"), Fortress Acquisition Corporation, a Delaware corporation
and a wholly owned subsidiary of Parent ("Sub"), Freegate Corporation, a
Delaware corporation (the "Company"), and, with respect to Article VII only,
James Mongiello, as Stockholder Representative, and U.S. Bank Trust, as Escrow
Agent.

                                    RECITALS

     A.   The Boards of Directors of each of the Company, Parent and Sub believe
it is in the best interests of each company and the stockholders of each company
that Parent acquire the Company through the statutory merger of Sub with and
into the Company (the "Merger") and, in furtherance thereof, have approved the
Merger.

     B.   Pursuant to the Merger, among other things, all of the issued and
outstanding shares of capital stock of the Company and all options, warrants and
other rights to acquire any shares of the Company shall be converted into the
right to receive shares of Common Stock of Parent.

     C.   A portion of the shares of Common Stock of Parent otherwise payable by
Parent in connection with the Merger shall be placed in escrow by Parent, the
release of which amount shall be contingent upon certain events and conditions.

     D.   It is intended by the parties hereto that the Merger shall constitute
a reorganization within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended (the "Code").

     E.   Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, Company and
each of the stockholders of the Company listed on Exhibit E-1 (collectively, the
"Principal Stockholders") shall execute and deliver a Support Agreement in
substantially the form attached hereto as Exhibit E-2 (the "Support Agreement")
agreeing to vote in favor of this Agreement and the Merger.

     G.   The Company, Parent and Sub desire to make certain representations,
warranties, covenants and other agreements in connection with the Merger.

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the parties agree as follows:
<PAGE>

                                   ARTICLE I

                                   The Merger

     1.1  The Merger.  At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of Delaware General Corporation Law (the "Delaware Law"),
Sub shall be merged with and into the Company, the separate corporate existence
of Sub shall cease and the Company shall continue as the surviving corporation
and as a wholly owned subsidiary of Parent. The surviving corporation after the
Merger is hereinafter sometimes referred to as the "Surviving Corporation."

     1.2  Effective Time.  Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than five (5) business days following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California,
or by exchange of original documentation by each of the respective parties'
attorneys via Federal Express or similar overnight courier service, unless
another place, manner or time is agreed to in writing by Parent and the Company.
The date upon which the Closing actually occurs is herein referred to as the
"Closing Date." On the Closing Date, the parties hereto shall cause the Merger
to be consummated by filing of a Certificate of Merger (or like instrument)
substantially in the form of Exhibit I (the "Merger Certificate") with the
Secretary of State of Delaware, in accordance with the relevant provisions of
applicable law (the time of acceptance by the Secretary of State of Delaware of
such filing, or such other time as may be agreed upon by the parties and set
forth in the Merger Certificate, being referred to herein as the "Effective
Time").

     1.3  Effect of the Merger.  At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of Delaware Law. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of the Company
and Sub shall vest in the Surviving Corporation, and all debts, liabilities and
duties of the Company and Sub shall become the debts, liabilities and duties of
the Surviving Corporation.

     1.4  Certificate of Incorporation; Bylaws.

          (a) Unless otherwise determined by Parent prior to the Effective Time,
at the Effective Time, the Certificate of Incorporation of Sub shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation; provided,
however, that Article I of the Certificate of Incorporation of the Surviving
Corporation shall be amended to read as follows:  "The name of the corporation
is Freegate Corporation."

          (b) The Bylaws of Sub, as in effect immediately prior to the Effective
Time, shall be the Bylaws of the Surviving Corporation until thereafter amended.

                                      -2-
<PAGE>

     1.5  Directors and Officers.  The director(s) of Sub immediately prior to
the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation. The officers of Sub
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.

     1.6  Effect on Capital Stock.  At the Effective Time, by virtue of the
Merger and without any action on the part of Sub, the Company or the holders of
any of the following securities:

          (a) Conversion of the Company Capital Stock.  Each share of Series A
Preferred Stock, $.0001 par value per share, of the Company (the "Company Series
A Stock") issued and outstanding immediately prior to the Effective Time, other
than shares, if any, for which dissenters rights have been or may be perfected
in compliance with applicable law, will be canceled and extinguished and be
converted automatically into the right to receive that number of shares  (the
"Series A Exchange Ratio") of the common stock, par value $0.001 per share, of
Parent ("Parent Common Stock") determined by dividing (i) $.06 by (ii) the
Parent Closing Price (as defined below).  Each share of Series B Preferred
Stock, $.0001 par value per share, of the Company (the "Company Series B Stock")
issued and outstanding immediately prior to the Effective Time, other than
shares, if any, for which dissenters rights have been or may be perfected in
compliance with applicable law, will be canceled and extinguished and be
converted automatically into the right to receive that number of shares (the
"Series B Exchange Ratio") of Parent Common Stock determined by dividing (i)
$.375 by (ii) the Parent Closing Price.  Each share of Series C Preferred Stock,
$.0001 par value per share, of the Company (the "Company Series C Stock") issued
and outstanding immediately prior to the Effective Time, other than shares, if
any, for which dissenters rights have been or may be perfected in compliance
with applicable law, will be canceled and extinguished and be converted
automatically into the right to that number of shares (the "Series C Exchange
Ratio") of Parent Common Stock determined by dividing (i) $.85 by (ii) the
Parent Closing Price. Each share of Series D Preferred Stock, $.0001 par value
per share, of the Company (the "Company Series D Stock") issued and outstanding
immediately prior to the Effective Time, other than shares, if any, for which
dissenters rights have been or may be perfected in compliance with applicable
law, will be canceled and extinguished and be converted automatically into the
right to receive that number of shares (the "Series D Exchange Ratio") of Parent
Common Stock determined by dividing (i) $1.50 by (ii) the Parent Closing Price.
Each share of common stock, $.0001 par value per share, of the Company (the
"Company Common Stock") issued and outstanding immediately prior to the
Effective Time, other than shares, if any, for which dissenters rights have been
or may be perfected in compliance with applicable law, will be canceled and
extinguished and be converted automatically into the right to receive that
number of shares (the "Common Exchange Ratio") of Parent Common Stock determined
by dividing (i) the Remaining Parent Shares to Be Issued (as defined below) by
(ii) the Common Shares Outstanding (as defined below). The Company Common Stock,
Company Series A Stock, Company Series B Stock, Company Series C Stock and the
Company Series D Stock shall hereinafter collectively be referred to as the
"Company Capital Stock." The Common Exchange Ratio, Series A Exchange Ratio,
Series B Exchange Ratio, Series C Exchange Ratio and Series D Exchange Ratio
shall hereinafter collectively be referred to as the "Exchange Ratio." The
shares of Parent Common Stock issued

                                      -3-
<PAGE>

pursuant to this Section 1.6(a) are referred to as the "Merger Shares."
Notwithstanding anything to the contrary contained in this Agreement, in no
event shall Parent be obligated to issue, pursuant to this Section 1.6(a) or
Section 1.6(d) below, any shares of Parent Common Stock in excess of the Total
Parent Shares to be Issued (as defined in subsection (c) below).

          (b) Shares Outstanding. The "Series A Shares Outstanding" shall equal
the total number of shares of Company Series A Stock issued and outstanding at
the Effective Time. The "Series B Shares Outstanding" shall equal the total
number of shares of Company Series B Stock issued and outstanding at the
Effective Time. The "Series C Shares Outstanding" shall equal the total number
of shares of Company Series C Stock issued and outstanding at the Effective
Time. The "Series D Shares Outstanding" shall equal the total number of shares
of Company Series D Stock issued and outstanding at the Effective Time. The
"Common Shares Outstanding" shall equal the total number of shares of Company
Common Stock issued and outstanding at the Effective Time plus the total number
of shares of Company Common Stock issuable upon exercise of all Company Options
listed on Exhibit H-1 attached hereto and outstanding at the Effective Time.
"Total Parent Shares to be Issued" shall equal (A) $21,000,000 divided by (B)
the average closing price as quoted on the Nasdaq National Market and as
reported in the Wall Street Journal of one share of Parent Common Stock for the
ten trading days prior to and including the trading day ending one day prior to
the date of this Agreement (the "Parent Closing Price").  "Remaining Parent
Shares to be Issued" shall equal (A) the Total Parent Shares to be Issued minus
(B) the sum of (i) the Series A Shares Outstanding multiplied by the Series A
Exchange Ratio, plus (ii) the Series B Shares Outstanding multiplied by the
Series B Exchange Ratio, plus (iii) the Series C Shares Outstanding multiplied
by the Series C Exchange Ratio, plus (iv) the Series D Shares Outstanding
multiplied by the Series D Exchange Ratio.

          (c) Shares Owned by Parent, etc.  Each share of the Company Capital
Stock issued and outstanding and owned by Parent, Sub or any of their
subsidiaries immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, cease to be
outstanding, be canceled and retired without payment of any consideration
therefor and cease to exist.

          (d) Company Options, Warrants, etc.  At the Effective Time, each
outstanding option to purchase shares of Company Capital Stock (each a "Company
Option") and each outstanding warrant or other right to purchase shares of the
Company Capital Stock (each a "Company Right"), whether vested or unvested,
shall be canceled and extinguished.  Parent shall issue in substitution for each
Company Option listed on Exhibit H-1 hereto a new option of equal remaining
tenor (a "Substitute Stock Option" and collectively "Substitute Stock Options")
to purchase a number of shares of Parent Common Stock equal to the product of
the number of shares of Company Common Stock covered by such Company Option
immediately prior to the Effective Time and as set forth on Exhibit H-1,
multiplied by the Common Exchange Ratio, rounded down to the nearest whole
number of shares of Parent Common Stock.  Each Substitute Stock Option shall
have a per share exercise price for the Parent Common Stock issuable upon the
exercise thereof equal to the quotient determined by dividing the exercise price
per share of Company Common Stock specified for each such Company Option under
the applicable option agreement immediately

                                      -4-
<PAGE>

prior to the Effective Time and as set forth on Exhibit H-1, by the Common
Exchange Ratio, rounding the resulting exercise price up to the nearest whole
cent. Parent shall reserve for issuance a sufficient number of shares of Parent
Common Stock for delivery upon the exercise of each Substitute Stock Option.
Each Substitute Stock Option shall be issued pursuant to and subject to the
terms and conditions of Parent's 1998 Stock Plan. No cash will be paid in lieu
of fractional shares which are rounded down pursuant to this section. It is the
intention of the parties hereto that, prior to the Effective Time, all
outstanding Company Options and Company Rights, other than those listed on
Exhibit H-1 hereto, will be exercised by the holders thereof.

          (e) Capital Stock of Sub. Each share of common stock, $.0001 par value
per share, of Sub issued and outstanding immediately prior to the Effective Time
shall be converted into and exchanged for one validly issued, fully paid and
nonassessable share of common stock, no par value, of the Surviving Corporation.
Each stock certificate of Sub evidencing ownership of any such shares shall
continue to evidence ownership of such shares of capital stock of the Surviving
Corporation.

          (f) Adjustments to Exchange Ratio.  The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Parent Common Stock or Company Capital Stock), reorganization, recapitalization
or other like change with respect to Parent Common Stock or Company Capital
Stock occurring after the date hereof and prior to the Effective Time, except
for any anticipated recapitalization expressly contemplated by this Agreement.

          (g) Fractional Shares. No fractional shares of Parent Common Stock
shall be issued in the Merger.  In lieu thereof, each holder of shares of the
Company Capital Stock (each, a "Company Stockholder") who would otherwise be
entitled to a fraction of a share of Parent Common Stock, shall (after
aggregating all fractional shares of Parent Common Stock to be received by such
holder), receive from Parent, promptly after the Effective Time, an amount of
cash equal to Parent Closing Price multiplied by the fraction of a share of
Parent Common Stock to which such holder would otherwise be entitled.

     1.7  Dissenting Shares.  Notwithstanding any provision of this Agreement to
the contrary, any shares of the Company Capital Stock that are outstanding
immediately prior to the Effective Time and that are held by Company
Stockholders who have not voted such shares in favor of the approval and
adoption of this Agreement and who shall have delivered a written demand for
appraisal of such shares in accordance with Section 262 of Delaware Law
("Dissenting Shares"), shall not be converted into or represent the right to
receive the Parent Common Stock as provided in Section 1.6 of this Agreement,
but the holders of such shares shall only be entitled to such rights as are
granted by Delaware Law; provided, however, that (i) if any holder of Dissenting
Shares shall subsequently deliver a written withdrawal of his demand for
appraisal of such shares (with the written approval of the Surviving
Corporation, if such withdrawal is not tendered within 60 days after the
Effective Time), or (ii) if any holder fails to perfect or loses his appraisal
rights as provided under Delaware Law, or (iii) if any holder of Dissenting
Shares fails to demand payment within the time period provided under Delaware
Law, such holder shall forfeit the right to appraisal of such

                                      -5-
<PAGE>

shares and such shares shall thereupon be deemed to have been converted into and
to have become exchangeable for, as of the Effective Time, the right to receive
Parent Common Stock as provided in Section 1.6 of this Agreement and in
accordance with Section 1.8 of this Agreement. The Company shall give Parent (i)
prompt notice of any written demands received by the Company to require the
Company to purchase shares of the Company Capital Stock, withdrawals of such
demands, and any other instruments served pursuant to Delaware Law and received
by the Company and (b) the opportunity to direct all negotiations and
proceedings with respect to such demands. The Company shall not, except with the
prior written consent of Parent, voluntarily make any payment with respect to
any such demands or offer to settle or settle any such demands.

     1.8  Surrender of Certificates.

          (a) Exchange Agent. American Stock Transfer & Trust shall serve as
exchange agent (the "Exchange Agent") in the Merger.

          (b) Parent to Provide Common Stock.  Promptly after the Effective
Time, Parent shall make available to the Exchange Agent for exchange in
accordance with this Article I the shares of Parent Common Stock issuable
pursuant to Section 1.6(a) in exchange for outstanding shares of the Company
Capital Stock; provided, however, that, on behalf of the Company Stockholders,
pursuant to Section 7.2 hereof, Parent shall deposit into an escrow account 10%
of the Merger Shares issued to the Escrow Agent on behalf of the Company
Stockholders pursuant to Section 1.6(a) (the "Escrow Amount"). The portion of
the Escrow Amount contributed on behalf of each Company Stockholder shall be in
proportion to the aggregate number of Merger Shares which such Company
Stockholder would otherwise be entitled to receive in the Merger by virtue of
ownership of outstanding shares of Company Capital Stock.

          (c) Exchange Procedures. Promptly after the Effective Time, the
Surviving Corporation shall cause to be mailed or provided at the Closing to
each Company Stockholder (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates (the
"Certificates"), which immediately prior to the Effective Time represented
outstanding shares of the Company Capital Stock whose shares were converted into
the right to receive Merger Shares pursuant to Section 1.6(a), shall pass, only
upon delivery of the Certificates to the Exchange Agent and shall be in such
form and have such other provisions consistent herewith as Parent may reasonably
specify) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing Merger Shares; provided,
however, that such letter of transmittal shall be substantially in the form and
substance of a letter of transmittal and instructions approved by counsel for
the Company at or before the Closing.  Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, a Company
Stockholder shall be entitled to receive in exchange therefor a certificate
representing the number of whole Merger Shares (less the number of shares of
Parent Common Stock to be deposited in the Escrow Fund on such holder's behalf
pursuant to paragraph (b) above) to which such Company Stockholder is entitled
pursuant to Section 1.6, and the Certificate so surrendered shall forthwith be
canceled.  As soon as practicable after the Effective

                                      -6-
<PAGE>

Time, and subject to and in accordance with the provisions of Article VII
hereof, Parent shall cause to be distributed to the Escrow Agent a certificate
or certificates representing that number of shares of Parent Common Stock equal
to the Escrow Amount, which shall be registered in the name of the Escrow Agent.
Such shares shall be beneficially owned by the holders on whose behalf such
shares were deposited in the Escrow Fund and shall be available to compensate
Parent as provided in Article VII. Until so surrendered, each outstanding
Certificate that, prior to the Effective Time, represented shares of the Company
Capital Stock will be deemed from and after the Effective Time, for all
corporate purposes, other than the payment of dividends, to evidence the
ownership of the number of full shares of Parent Common Stock into which such
shares of the Company Capital Stock shall have been so converted.

          (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock represented thereby until the holder of record of such Certificate
shall surrender such Certificate.  Subject to applicable law, following
surrender of any such Certificate, there shall be paid to the record holder of
the certificates representing whole shares of Parent Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount
of dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Parent Common Stock.

          (e) Transfers of Ownership.  If any certificate for shares of Parent
Common Stock is to be issued in a name other than that in which the certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

          (f) Lost, Stolen or Destroyed Certificates.  In the event any
certificates evidencing shares of the Company Capital Stock shall have been
lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such
lost, stolen or destroyed certificates, upon the making of an affidavit of that
fact by the holder thereof, such shares of Parent Common Stock; provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the certificates alleged to have been lost, stolen or
destroyed.

          (g) No Liability.  Notwithstanding anything to the contrary in this
Section 1.8, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Parent Common Stock or Company
Capital Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                                      -7-
<PAGE>

     1.9  No Further Ownership Rights in Company Capital Stock.  All shares of
Parent Common Stock issued upon the surrender for exchange of shares of the
Company Capital Stock in accordance with the terms hereof shall be deemed to be
full satisfaction of all rights pertaining to such shares of the Company Capital
Stock, and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of the Company Capital Stock that were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

     1.10 Dissenting Shares After Payment of Fair Value.  Dissenting Shares, if
any, after payments in respect thereto have been made pursuant to the Delaware
Law, shall be canceled.

     1.11 Tax and Accounting Consequences.  It is intended by the parties hereto
that the Merger shall constitute a reorganization within the meaning of Section
368 of the Code and constitute a purchase for accounting purposes. Each party
has consulted with its own tax advisors and accountants with respect to the tax
and accounting consequences, respectively, of the Merger.

     1.12 Hart-Scott-Rodino Filings.  Each of Parent and the Company will
promptly prepare and file the applicable notices (if any) required to be filed
by it under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR
Act"), and comply promptly with any requests to it from the Federal Trade
Commission or United States Department of Justice for additional information.

     1.13 Taking of Necessary Action; Further Action.  If, at any time after the
Effective Time, any such further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Sub, the officers and directors of the Company
and Sub are fully authorized in the name of their respective corporations or
otherwise to take, and will take, all such lawful and necessary action.

                                   ARTICLE II

                 Representations and Warranties of the Company

     The Company represents and warrants to Parent and Sub, subject to such
exceptions as are specifically disclosed in the Disclosure Schedule (referencing
the appropriate section and paragraph numbers) supplied by the Company to Parent
(the "Disclosure Schedule") and dated as of the date hereof, as set forth below.
"To the knowledge of the Company" means to the actual knowledge, after due
inquiry, of the officers of the Company.

     2.1  Organization of the Company.  The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. The Company has the corporate power to own its properties and to carry
on its business as now being conducted. The

<PAGE>

Company is duly qualified to do business and in good standing as a foreign
corporation in each jurisdiction in which the failure to be so qualified would
have a material adverse effect on the business, assets (including intangible
assets), financial condition, results of operations or prospects of the Company
(hereinafter referred to as a "Material Adverse Effect"). The Company has
delivered a true and correct copy of its Certificate of Incorporation and
Bylaws, each as amended to date, to Parent. Section 2.1 of the Disclosure

                             Additional Agreements

     5.1  Preparation of Permit Application, Hearing Request, Hearing Notice and
Information Statement.  As promptly as practicable after any determination by
Parent or its legal counsel of the unavailability of Rule 506 as an exemption
from registration under the Securities Act for the issuance of Parent Common
Stock in connection with the Merger, Parent and the Company shall prepare and
file with the California Commissioner of Corporations the documents required by
the California Corporate Securities Law of 1968, as amended (the "CCSL")
including, but not limited to, any required "Permit Application," "Hearing
Request," and "Hearing Notice", pursuant to Sections 25121 and 25142 of the CCSL
(collectively, the "Notice Materials"), in connection with the Merger, in order
to perfect the exemption from registration provided by Section 3(a)(10) of the
Securities Act. Each of Parent and the Company shall use reasonable efforts to

practicable date to submit this Agreement, the Merger and related matters for
the consideration and approval of the Company Stockholders, which approval will
be recommended by Company's Board of Directors and management. Such Information
Statement will contain information, and will be solicited, in compliance with
applicable law. Each of Parent and the Company will promptly provide all
information relating to their respective business and operations necessary for
inclusion in the Notice Materials to satisfy all requirements of applicable
state and federal securities laws. Each of Parent and the Company shall be

as practicable, and in any event (to the extent permissible under applicable
law) no more than ten (10) days after the California Commissioner of
Corporations has issued a permit declaring the Permit Application, Hearing
Request and Hearing Notice with respect to the Merger effective, for the purpose
of voting upon approval of this Agreement and the Merger. The Company will
solicit from its stockholders proxies in favor of the approval of this Agreement
and the Merger, and will use its commercially reasonable efforts to take all
other action necessary or advisable to secure the vote or consent of its
stockholders required by the rules of California Law and Delaware Law to obtain
such approvals. Notwithstanding anything to the contrary contained in this
Agreement, Company may adjourn or postpone the Company Stockholders' Meeting if
as of the time for which the Company Stockholders' Meeting is originally
scheduled there are insufficient shares of the Company Capital Stock represented
(either in person or by proxy) to constitute a quorum necessary to conduct the
business of the Company Stockholders' Meeting. The Company will use its
commercially reasonable efforts to ensure that all proxies solicited by Company
in connection with the Company Stockholders' Meeting are solicited in compliance
with the Delaware Law, California Law, its Certificate of Incorporation and
Bylaws, and all other applicable legal requirements. The Company's obligation to
call, give notice of, convene, hold and conduct the Company Stockholders'
Meeting in accordance with this Section 5.3(a) shall not be limited to or
otherwise affected by the commencement, disclosure, announcement or submission
to Company of any proposal by a third party to acquire the Company, or by any
withdrawal, amendment or modification of the recommendation of the Board of
Directors of the Company to the Company Stockholders to approve this Agreement
and the Merger.

          (b) The Board of Directors of the Company shall recommend that the
Company Stockholders vote in favor of and approve this Agreement and the Merger
at the Company Stockholders' Meeting, the Information Statement shall include a
statement to the effect that the Board of Directors of the Company has

amend or modify, or propose or resolve to withdraw, amend or modify in a manner
adverse to Parent, the recommendation of the Board of Directors of the Company
that Company's stockholders vote in favor of and approve this Agreement and the
Merger.

     5.3  Regulatory Approvals.  The Company will execute and file, or join in
the execution and filing, of any application or other document that may be
necessary in order to obtain the authorization, approval or consent of any
governmental body, federal, state, local or foreign, which may be reasonably
required, or which Parent may reasonably request, in connection with the
consummation of the transactions provided for in this Agreement. The Company

authorizations, approvals and consents.

accountants, counsel and other representatives reasonable access during normal

                                      -33-

reasonably request. The Company agrees to provide to Parent and its accountants,
counsel and other representatives copies of internal financial statements
promptly upon request. Parent shall provide the Company with copies of such
publicly available information about Parent as the Company may request and shall
provide the Company with reasonable access to its executive officers in this

Company, all Third Party Expenses shall be either paid or accrued by the Company
prior to the Effective Time. Parent agrees that if the Merger is consummated,
Parent will guarantee the payment of all Third Party Expenses which are
described in Section 2.21 of the Disclosure Schedule and which are incurred and
accrued for but not paid by the Company prior to the Effective Time.

     5.7  Public Disclosure.  Unless otherwise required by law, prior to the
Effective Time, no disclosure (whether or not in response to an inquiry) of the
subject matter of this Agreement shall be made by any party hereto unless

consents, waivers and approvals under any of the Contracts as may be required in
connection with the Merger (all of such consents, waivers and approvals are set
forth in Disclosure Schedule) so as to preserve all rights of, and benefits to,
the Company thereunder.

this Agreement, each of the parties hereto shall use commercially reasonable
efforts to take promptly, or cause to be taken, all actions, and to do promptly,
or cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated hereby, to obtain all necessary waivers, consents and approvals and

or other impediments or delays, legal or otherwise, in order to consummate and
make effective the transactions contemplated by this Agreement for the purpose
of securing to the parties hereto the benefits contemplated by this Agreement;
provided, however, that Parent shall not be required to agree to any divestiture
by Parent or the Company or any of Parent's subsidiaries or affiliates of shares
of capital stock or of any business, assets or property of Parent or its

the case may be, to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it hereunder; provided, however, that the
delivery of any notice pursuant to this Section 5.11 shall not limit or
otherwise affect any remedies available to the party receiving such notice.

     5.12 Business Arrangements.  In anticipation of the Closing, Parent and the
Company agree to negotiate in good faith a strategic alliance arrangement
pursuant to which the business operations of Parent and the Company will be
integrated to the greatest extent mutually agreeble to Parent and the Company.
It is the parties intentions that the final terms of such strategic alliance
arrangement will adequately protect each of the Company's and Parent's
intellectual property, assets, confidential information and other relevant
property and relationships in the event that this Agreement is terminated and
the Closing does not occur. In addition to the strategic alliance arrangement
discussed above, Parent agrees to use its best efforts to lend, on terms
comparable to lending terms available to the Company from commercial lenders and
to be negotiated in good faith between Parent and the Company, in an amount
necessary to meet the Company's needs for working capital during the period
prior to the earlier to occur of the Closing Date or the termination of this
Agreement.

                                  ARTICLE VII

              Survival of Representations and Warranties; Escrow

     7.1  Survival of Representations and Warranties. All of the Company's
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement shall survive the Merger and continue until the date
which is one year following the Closing Date (the "Expiration Date"). All of
Parent's and Sub's representations and warranties contained herein or in any
instrument delivered pursuant to this Agreement shall terminate at the
Expiration Date. Except for the representations and warranties contained in
Article 2 of this Agreement, the Company makes no other express or implied
representation or warranty to Parent or Sub. Parent and Sub acknowledge that, in
entering into this Agreement, they have not relied on any representations or
warranties of the Company other than the representations and warranties of the
Company set forth in Article 2 of this Agreement.

     7.2  Escrow Arrangements.

          (a) Escrow Fund.  As security for the indemnity provided for in this
Section 7.2 and by virtue of this Agreement, the Company Stockholders will be
deemed to have received and deposited with the Escrow Agent (as defined below)
the Escrow Amount (plus any additional shares as may be issued upon any stock
split, stock dividend or recapitalization effected by Parent after the Effective
Time) without any act of any Company Stockholder.  As soon as practicable after
the Effective Time, the Escrow Amount, without any act of any Company
Stockholder, will be deposited with U.S. Bank Trust (or other institution
acceptable to Parent and the Company Stockholders) as Escrow Agent (the "Escrow
Agent"), such deposit to constitute an escrow fund (the "Escrow Fund") to be
governed by the terms set forth herein.  The Escrow Agent may execute this
Agreement following the date hereof and prior to the Effective Time, and such
later execution, if so executed after the date hereof, shall not affect the
binding nature of this Agreement as of the date hereof between the other
signatories hereto.  The portion of the Escrow Amount contributed on behalf of
each Company Stockholder shall be in proportion to the aggregate Parent Common
Stock which such holder would otherwise be entitled under Section 1.6(a).  The
Company and the Company Stockholders jointly agree to indemnify and hold Parent
and its officers, directors and affiliates (the "Indemnified Parties") harmless
against all claims, losses, liabilities, damages, deficiencies, costs and
expenses, including reasonable attorneys' fees and expenses of investigation
(hereinafter individually a "Loss" and collectively "Losses") incurred by
Parent, its officers, directors, or affiliates (including the Surviving
Corporation) directly or indirectly as a result of (i) any inaccuracy or breach
of a representation or warranty of the Company contained in this Agreement, or
(ii) any failure by the Company to perform or comply with any covenant contained
in this Agreement; provided, however, that, except as set forth in Section 7.4,
the aggregate amount for which the Company Stockholders are required to
indemnify the Indemnified Parties shall not exceed the amount deposited in the
Escrow Fund. The Escrow Fund shall be available to compensate Parent and its
affiliates for any such Losses.  The Company Stockholders shall not have any
right of contribution from the Company with respect to any Loss claimed by
Parent after the Effective Time.  Nothing herein shall limit the liability of
the Company for any breach of any representation,

                                      -42-
<PAGE>

warranty or covenant if the Merger does not close for reasons other than
Parent's breach of its obligations hereunder; but the Company Stockholders shall
not be personally liable therefor. Parent may not receive any shares from the
Escrow Fund unless and until an Officer's Certificate (as defined in paragraph
(d) below) identifying Losses has been delivered to the Escrow Agent as provided
in paragraph (d) below.

          (b) Escrow Period; Distribution upon Termination of Escrow Periods.
Subject to the following requirements, the Escrow Fund shall be in existence
immediately following the Effective Time and shall terminate on the Expiration
Date (the "Escrow Period"); provided, however, that the Escrow Period shall not
terminate with respect to any amount which, in the reasonable judgement of
Parent, subject to the objection of the Stockholder Representative (as defined
in Section 7.3 below) and the subsequent arbitration of the matter in the manner
provided in Section 7.2(f) hereof, is necessary to satisfy any unsatisfied
claims specified in any Officer's Certificate delivered to the Escrow Agent
prior to termination of such Escrow Period with respect to facts and
circumstances existing prior to the termination of such Escrow Period.  As soon
as all such claims have been resolved, the Escrow Agent shall deliver to the
Company Stockholders the remaining portion of the Escrow Fund not required to
satisfy such claims.  Deliveries of Escrow Amounts to the Company Stockholders
pursuant to this Section 7.2(b) shall be made in proportion to their respective
original contributions to the Escrow Fund.

          (c)  Protection of Escrow Fund.

               (i)   The Escrow Agent shall hold and safeguard the Escrow Fund
during the Escrow Period, shall treat such fund as a trust fund in accordance
with the terms of this Agreement and not as the property of Parent and shall
hold and dispose of the Escrow Fund only in accordance with the terms hereof.

               (ii)  Any shares of Parent Common Stock or other equity
securities issued or distributed by Parent (including shares issued upon a stock
split) ("New Shares") in respect of Parent Common Stock in the Escrow Fund which
have not been released from the Escrow Fund shall be added to the Escrow Fund
and become a part thereof. New Shares issued in respect of shares of Parent
Common Stock which have been released from the Escrow Fund shall not be added to
the Escrow Fund but shall be distributed to the record holders thereof. Cash
dividends on Parent Common Stock shall not be added to the Escrow Fund but shall
be distributed to the record holders thereof.

               (iii) Each Company Stockholder shall have voting rights with
respect to the shares of Parent Common Stock contributed to the Escrow Fund by
such Company Stockholder (and on any voting securities added to the Escrow Fund
in respect of such shares of Parent Common Stock).

          (d)  Claims Upon Escrow Fund.

               (i)   Upon receipt by the Escrow Agent at any time on or before
the last day of the Escrow Period of a certificate signed by any officer of
Parent (an "Officer's Certificate"):

                                      -43-
<PAGE>

(A) stating that Parent has paid or properly accrued or reasonably anticipates
that it will have to pay or accrue Losses, and (B) specifying in reasonable
detail the individual items of Losses included in the amount so stated, the date
each such item was paid or properly accrued, or the basis for such anticipated
liability, and the nature of the misrepresentation, breach of warranty or
covenant to which such item is related, the Escrow Agent shall, subject to the
provisions of Section 7.2(e) hereof, deliver to Parent out of the Escrow Fund,
as promptly as practicable, shares of Parent Common Stock held in the Escrow
Fund with a value equal to such Losses; provided, however, that Parent may not
receive any shares from the Escrow Fund unless and until one or more Officer's
Certificatesi identifying Losses in excess of Fifty Thousand Dollars ($50,000)
in the aggreate (the "Basket Amount") has or have been delivered to the Escrow
Agent as provided in this Article VII, in which case Parent shall be entitled to
recover all Losses so identified, including without limitation, the Basket
Amount.

               (ii)  For the purposes of determining the number of shares of
Parent Common Stock to be delivered to Parent out of the Escrow Fund as
indemnity pursuant to Section 7.2(d)(i) hereof, the shares of Parent Common
Stock shall be valued at the Parent Closing Price.

          (e)  Objections to Claims.  At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Stockholder Representatives, and for a period of thirty (30)
days after such delivery, the Escrow Agent shall make no delivery to Parent of
any Escrow Amounts pursuant to Section 7.2(d) hereof unless the Escrow Agent
shall have received written authorization from the Stockholder Representative to
make such delivery.  After the expiration of such thirty (30) day period, the
Escrow Agent shall make delivery of shares of Parent Common Stock from the
Escrow Fund in accordance with Section 7.2(d) hereof; provided, however, that no
such payment or delivery may be made if the Stockholder Representative shall
object in a written statement to the claim made in the Officer's Certificate,
and such statement shall have been delivered to the Escrow Agent prior to the
expiration of such thirty (30) day period.

          (f)  Resolution of Conflicts; Arbitration.

               (i) In case the Stockholder Representative shall object in
writing to any claim or claims made in any Officer's Certificate, the
Stockholder Representative and Parent shall attempt in good faith to agree upon
the rights of the respective parties with respect to each of such claims. If the
Stockholder Representative and Parent should so agree, a memorandum setting
forth such agreement shall be prepared and signed by both parties and shall be
furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any
such memorandum and distribute shares of Parent Common Stock from the Escrow
Fund in accordance with the terms thereof.

               (ii) If no such agreement can be reached after good faith
negotiation, either Parent or the Stockholder Representative may demand
arbitration of the matter unless the amount of the damage or Loss is at issue in
pending litigation with a third party, in which event arbitration shall not be
commenced until such amount is ascertained or both parties agree to arbitration;
and in either such event the matter shall be settled by arbitration conducted by
one

                                      -44-
<PAGE>

arbitrator mutually agreeable to Parent and the Stockholder Representative. In
the event that within forty-five (45) days after submission of any dispute to
arbitration, Parent and the Stockholder Representative cannot mutually agree on
one arbitrator, Parent and the Stockholder Representative shall each select one
arbitrator, and the two arbitrators so selected shall select a third arbitrator.
The arbitrator or arbitrators, as the case may be, shall set a limited time
period and establish procedures designed to reduce the cost and time for
discovery while allowing the parties an opportunity, adequate in the sole
judgement of the arbitrator or majority of the three arbitrators, as the case
may be, to discover relevant information from the opposing parties about the
subject matter of the dispute. The arbitrator or a majority of the three
arbitrators, as the case may be, shall Rule upon motions to compel or limit
discovery and shall have the authority to impose sanctions, including attorneys'
fees and costs, to the same extent as a competent court of law or equity, should
the arbitrators or a majority of the three arbitrators, as the case may be,
determine that discovery was sought without substantial justification or that
discovery was refused or objected to without substantial justification. The
decision of the arbitrator or a majority of the three arbitrators, as the case
may be, as to the validity and amount of any claim in such Officer's Certificate
shall be binding and conclusive upon the parties to this Agreement. Such
decision shall be written and shall be supported by written findings of fact and
conclusions which shall set forth the award, judgment, decree or order awarded
by the arbitrator(s).

               (iii)  Judgment upon any award rendered by the arbitrator(s) may
be entered in any court having jurisdiction. Any such arbitration shall be held
in San Francisco County, California, under the rules then in effect of the
American Arbitration Association. The arbitrator(s) shall determine how all
expenses relating to the arbitration shall be paid, including without
limitation, the respective expenses of each party, the fees of each arbitrator
and the administrative fee of the American Arbitration Association.

          (g)  Third-Party Claims. In the event Parent becomes aware of a third-
party claim which Parent believes may result in a demand against the Escrow
Fund, Parent shall notify the Stockholder Representative of such claim, and the
Company Stockholders shall be entitled, at their expense, to participate in any
defense of such claim. Parent shall have the right in its sole discretion to
settle any such claim; provided, however, that except with the consent of the
Stockholder Representative, no settlement of any such claim with third-party
claimants shall be determinative of the amount of any claim against the Escrow
Fund. In the event that the Stockholder Representative has consented to any such
settlement, the Company Stockholders shall have no power or authority to object
under any provision of this Article VII to the amount of any claim by Parent
against the Escrow Fund with respect to such settlement.

          (h)  Escrow Agent's Duties.

               (i)    The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions which the Escrow Agent may
receive after the date of this Agreement which are signed by an officer of
Parent and the Stockholder Representative, and may rely and shall be protected
in relying or refraining from acting on any instrument reasonably believed to be
genuine and to have

                                      -45-
<PAGE>

been signed or presented by the proper party or parties. The Escrow Agent shall
not be liable for any act done or omitted hereunder as Escrow Agent while acting
in good faith and in the exercise of reasonable judgment, and any act done or
omitted pursuant to the advice of counsel shall be conclusive evidence of such
good faith.

               (ii)   The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person, excepting only orders or process of courts of law, and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree of any court, the Escrow Agent shall not be liable to any of the
parties hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently reversed,
modified, annulled, set aside, vacated or found to have been entered without
jurisdiction.

               (iii)  The Escrow Agent shall not be liable in any respect on
account of the identity, authority or rights of the parties executing or
delivering or purporting to execute or deliver this Agreement or any documents
or papers deposited or called for hereunder.

               (iv)   The Escrow Agent shall not be liable for the expiration of
any rights under any statute of limitations with respect to this Agreement or
any documents deposited with the Escrow Agent.

               (v)    In performing any duties under the Agreement, the Escrow
Agent shall not be liable to any party for damages, losses, or expenses, except
for negligence or willful misconduct on the part of the Escrow Agent. The Escrow
Agent shall not incur any such liability for (A) any act or failure to act made
or omitted in good faith, or (B) any action taken or omitted in reliance upon
any instrument, including any written statement of affidavit provided for in
this Agreement that the Escrow Agent shall in good faith believe to be genuine,
nor will the Escrow Agent be liable or responsible for forgeries, fraud,
impersonations, or determining the scope of any representative authority. In
addition, the Escrow Agent may consult with the legal counsel in connection with
Escrow Agent's duties under this Agreement and shall be fully protected in any
act taken, suffered, or permitted by him/her in good faith in accordance with
the advice of counsel. The Escrow Agent is not responsible for determining and
verifying the authority of any person acting or purporting to act on behalf of
any party to this Agreement.

               (vi)   If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
shall hold all documents and shares of Parent Common Stock and shall wait for
settlement of any such controversy by final appropriate legal proceedings or
other means as, in the Escrow Agent's discretion, the Escrow Agent may be
required, despite what may be set forth elsewhere in this Agreement. In such
event, the Escrow Agent will not be liable for damage. Furthermore, the Escrow
Agent may at its option, file an action of interpleader requiring the parties to
answer and litigate any claims and rights among themselves. The Escrow Agent is
authorized to deposit with the clerk of the court all documents and shares of
Parent Common Stock held in escrow,

                                      -46-
<PAGE>

except all cost, expenses, charges and reasonable attorney fees incurred by the
Escrow Agent due to the interpleader action and which the parties jointly and
severally agree to pay. Upon initiating such action, the Escrow Agent shall be
fully released and discharged of and from all obligations and liability imposed
by the terms of this Agreement.

               (vii)  The parties and their respective successors and assigns
agree jointly and severally to indemnify and hold Escrow Agent harmless against
any and all losses, claims, damages, liabilities, and expenses, including
reasonable costs of investigation, counsel fees, including allocated costs of
in-house counsel and disbursements that may be imposed on Escrow Agent or
incurred by Escrow Agent in connection with the performance of his/her duties
under this Agreement, including but not limited to any litigation arising from
this Agreement or involving its subject matter other than arising out of its
negligence or willful misconduct.

               (viii) The Escrow Agent may resign at any time upon giving at
least thirty (30) days written notice to the parties; provided, however, that no
such resignation shall become effective until the appointment of a successor
escrow agent which shall be accomplished as follows: the parties shall use their
best efforts to mutually agree on a successor escrow agent within thirty (30)
days after receiving such notice. If the parties fail to agree upon a successor
escrow agent within such time, the Escrow Agent shall have the right to appoint
a successor escrow agent authorized to do business in the state of California.
The successor escrow agent shall execute and deliver an instrument accepting
such appointment and it shall, without further acts, be vested with all the
estates, properties, rights, powers, and duties of the predecessor escrow agent
as if originally named as escrow agent. Upon appointment of a successor escrow
agent, the Escrow Agent shall be discharged from any further duties and
liability under this Agreement.

          (i)  Fees.  All fees of the Escrow Agent for performance of its duties
hereunder shall be paid by Parent in accordance with the standard fee schedule
of the Escrow Agent, attached hereto as Exhibit F.  It is understood that the
fees and usual charges agreed upon for services of the Escrow Agent shall be
considered compensation for ordinary services as contemplated by this Agreement.
In the event that the conditions of this Agreement are not promptly fulfilled,
or if the Escrow Agent renders any service not provided for in this Agreement,
or if the parties request a substantial modification of its terms, or if any
controversy arises, or if the Escrow Agent is made a party to, or intervenes in,
any litigation pertaining to the Escrow Fund or its subject matter, the Escrow
Agent shall be reasonably compensated for such extraordinary services and
reimbursed for all costs, attorney's fees, including allocated costs of in-house
counsel, and expenses occasioned by such default, delay, controversy or
litigation.

          (j)  Consequential Damages.  In no event shall the Escrow Agent be
liable for special, indirect or consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Escrow Agent
has been advised of the likelihood of such loss or damage and regardless of the
form of action.

          (k)  Successor Escrow Agents.  Any corporation into which the Escrow
Agent in its individual capacity may be merged or converted or with which it may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Escrow Agent in its

                                      -47-
<PAGE>

individual capacity shall be a party, or any corporation to which substantially
all the corporate trust business of the Escrow Agent in its individual capacity
may be transferred, shall be the Escrow Agent under this Escrow Agreement
without further act.

     7.3  Stockholder Representative.

          (a)  In the event that the Merger is approved, effective upon such
vote, and without further act of any Company Stockholder, James Mongiello shall
be appointed as agent and attorney-in-fact (the "Stockholder Representative")
for each Company Stockholder, for and on behalf of the Company Stockholders, to
give and receive notices and communications, to authorize delivery to Parent of
shares of Parent Common Stock from the Escrow Fund in satisfaction of claims by
Parent, to object to such deliveries, to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders of
courts and awards of arbitrators with respect to such claims, and to take all
actions necessary or appropriate in the judgment of the Stockholder
Representative for the accomplishment of the foregoing.  Such agency may be
changed by the Company Stockholders from time to time upon not less than thirty
(30) days prior written notice to Parent; provided, however, that the
Stockholder Representative may not be removed unless holders of a two-thirds
interest in the Escrow Fund agree to such removal and to the identity of the
substituted agent.  Any vacancy in the position of Stockholder Representative
may be filled by approval of the holders of a majority in interest in the Escrow
Fund.  No bond shall be required of the Stockholder Representatives, and a
Stockholder Representative shall not receive compensation for his or her
services.  Notices or communications to or from the Stockholder Representatives
shall constitute notice to or from each of the Company Stockholder.

          (b)  The Stockholder Representative shall not be liable for any act
done or omitted hereunder as Stockholder Representative while acting in good
faith and in the exercise of reasonable judgment.  The Company Stockholders on
whose behalf the Escrow Amount was contributed to the Escrow Fund shall
severally indemnify the Stockholder Representative and hold the Stockholder
Representative harmless against any loss, liability or expense incurred without
negligence or bad faith on the part of the Stockholder Representative and
arising out of or in connection with the acceptance or administration of the
Stockholder Representative's duties hereunder, including the reasonable fees and
expenses of any legal counsel retained by the Stockholder Representative.

          (c)  A decision, act, consent or instruction of the Stockholder
Representative shall constitute a decision of all Company Stockholders for whom
a portion of the Escrow Amount otherwise issuable to them are deposited in the
Escrow Fund and shall be final, binding and conclusive upon each of such Company
Stockholders, and the Escrow Agent and Parent may rely upon any such decision,
act, consent or instruction of the Stockholder Representatives as being the
decision, act, consent or instruction of each and every such Company
Stockholder.  The Escrow Agent and Parent are hereby relieved from any liability
to any person for any acts done by them in accordance with such decision, act,
consent or instruction of the Stockholder Representative.

     7.4  Exclusive Remedy. The indemnity set forth in this Article VII and the
Escrow Fund provided for herein shall apply only to breaches by the Company of
any representation, warranty, covenant or agreement of the Company contained
herein, by reason of any misrepresentation by the

                                      -48-
<PAGE>

Company made in or pursuant to Article II of this Agreement, and, except as
provided below, resort to the Escrow Fund shall be the exclusive right and
remedy of Parent for such breaches, or otherwise under or in connection with
this Agreement, once the Closing occurs. Notwithstanding the foregoing, the
existence of this Article VII and of the rights and restrictions set forth
herein do not limit any other potential remedies of Parent with respect to any
knowing and intentional or fraudulent actual breaches of the representations and
warranties or covenants of the Company contained in any Article of this
Agreement; provided, however, that, unless such Company Stockholder was
personally aware that such breach was knowing and intentional or fraudulent,
such Company Stockholder shall not have liability under the preceding clause in
an amount greater than the aggregate Merger Shares to be issued to such Company
Stockholder pursuant to Section 1.6 of this Agreement, nor shall any liability
be asserted against such Company Stockholder after November 16, 2001 for any
such knowing and intentional or fraudulent actual breach of the representations
and warranties or covenants of the Company contained in any Article of this
Agreement.

                                 ARTICLE VIII

                       Termination, Amendment and Waiver

     8.1  Termination.  Except as provided in Section 8.2 below, this Agreement
may be terminated and the Merger abandoned at any time prior to the Effective
Time:

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

          (b) by Parent or the Company if: (i) the Effective Time has not
occurred by March 31, 2000, or by June 30, 2000 in the event that a Registration
Statement on Form S-4 is required under the Securities Act in order to
consummate the Merger; (ii) there shall be a final nonappealable order of a
federal or state court in effect preventing consummation of the Merger; or (iii)
there shall be any statute, rule, regulation or order enacted, promulgated or
issued or deemed applicable to the Merger by any Governmental Entity that would
make consummation of the Merger illegal;

          (c) by Parent if there shall be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger by any Governmental Entity, which would: (i) prohibit Parent's or
Sub's ownership or operation of any portion of the business of the Company or
(ii) compel Parent or the Company to dispose of or hold separate all or a
portion of the business or assets of the Company or Parent as a result of the
Merger;

          (d) by Parent if it is not in material breach of its obligations under
this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of the
Company and such breach has not been cured within ten (10) calendar days after
written notice to the Company; provided, however, that, no cure period shall be
required for a breach which by its nature cannot be cured;

                                      -49-
<PAGE>

          (e) by the Company if it is not in material breach of its obligations
under this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of
Parent or Sub and such breach has not been cured within ten (10) calendar days
after written notice to Parent; provided, however, that, no cure period shall be
required for a breach which by its nature cannot be cured; or

          (f) by Parent if the required approval of the Company Stockholders
contemplated by this Agreement shall not have been obtained by reason of the
failure of the Principal Stockholders to fulfill their obligations under the
Support Agreement.

     Where action is taken to terminate this Agreement pursuant to this Section
8.1, it shall be sufficient for such action to be authorized by the Board of
Directors (as applicable) of the party taking such action.

     8.2  Effect of Termination.  In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of Parent, Sub, the Company, or
their respective officers, directors or stockholders; provided, however, that
each party shall remain liable for any breaches of this Agreement prior to its
termination; and provided, further, that the provisions of Sections 5.5, 5.6,
5.7 and this Article VIII of this Agreement shall remain in full force and
effect and survive any termination of this Agreement.

     8.3  Amendment.  This Agreement may be amended by the parties hereto at any
time by execution of an instrument in writing signed on behalf of each of the
parties hereto.

     8.4  Extension; Waiver.  At any time prior to the Effective Time, Parent
and Sub, on the one hand, and the Company, on the other, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

                                   ARTICLE IX

used herein shall be deemed in each case to be followed by the words "without
limitation." The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     9.3  Counterparts.  This Agreement may be executed in one or more

shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all

     9.4  Entire Agreement; Assignment.  This Agreement, the Exhibits hereto and
the Disclosure Schedule, and the documents and instruments and other agreements

made this 20th day of  December 1999, by and between Tut Systems, Inc., a

                                                ---------

     WHEREAS, as a material inducement to certain shareholders of the Company to
vote in favor of the Merger, the parties hereto desire to amend the Agreement as
set forth herein;

     NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and adequacy of which is hereby

deemed amended as necessary to provide as follows.

          1.  Amendment of Article VII, Section 7.3(b). Section 7.3(b) of the

shall be final, binding and conclusive upon each of such Company Stockholders,
and the Escrow Agent and Parent may rely upon any such decision, act, consent or
instruction of the Stockholder Representatives as being the decision, act,
consent or instruction of each and every such Company Stockholder.  The Escrow
Agent and Parent are hereby relieved from any liability to any person for any
acts done by them in accordance with such decision, act, consent or instruction
of the Stockholder Representative."

              ---------
