     This AGREEMENT AND PLAN OF MERGER is made and entered into as of October

VideoTele.com, Inc., an Oregon corporation and a majority-owned subsidiary of
Parent ("Company").

                                    RECITALS

     WHEREAS, upon the terms and subject to the conditions set forth herein and
in accordance with the provisions of the Oregon Business Corporation Act (the
"OBCA"), Purchaser, Merger Sub, Parent and Company are entering into a business
combination pursuant to which Merger Sub will merge with and into Company, with
the result that Company shall be the surviving corporation and shall become a
wholly-owned subsidiary of Purchaser, all upon the terms and conditions set
forth herein.

     WHEREAS, the Boards of Directors of Purchaser, Merger Sub, and Company have
(i) determined that the Merger is consistent with and in furtherance of their
long-term business strategies and fair to, advisable and in the best interests
of their respective securityholders; (ii) approved this Agreement and all other
agreements and transactions contemplated by this Agreement; and (iii) in the
case of the Board of Directors of Company, determined to recommend that its
shareholders vote to approve the Merger.

     WHEREAS, Parent has approved the Agreement and all other agreements
contemplated by the Agreement to which it is or will be a party.

     NOW, THEREFORE, in consideration of the mutual covenants set forth herein
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto, intending to be legally
bound, hereby agree as follows:

                                    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 the OBCA, Merger Sub shall be merged with and into
Company (the "Merger"), the separate corporate existence of the Merger Sub shall
cease and Company shall continue as the surviving corporation. Company as the
surviving corporation after the Merger is hereinafter sometimes referred to as
the "Surviving Corporation."

     1.2 Effective Time; Closing. Subject to the provisions of this Agreement,
the parties hereto shall cause the Merger to be consummated by filing articles
of merger in the form attached as Exhibit A with the Secretary of State of the
State of Oregon in accordance with the relevant provisions of Oregon law (the
"Merger Documents") (the time of such filing (or such later time as



may be agreed in writing by Company and Purchaser and specified in the Merger
Documents) being the "Effective Time") as soon as practicable on or after the
Closing Date (as herein defined). Unless the context otherwise requires, the
term "Agreement" as used herein refers collectively to this Agreement and Plan
of Merger and the articles of merger. The closing of the Merger (the "Closing")
shall take place at the offices of Stoel Rives LLP, at a time and date to be
specified by the parties, which shall be no later than the second business day
after the satisfaction or waiver of the conditions set forth in Article VII, or
at such other time, date and location as the parties hereto agree in writing
(the "Closing Date").

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

     1.4 Articles of Incorporation; Bylaws.

         (a) At the Effective Time, the Articles of Incorporation of Merger Sub,
as in effect immediately prior to the Effective Time, shall be the Articles of
Incorporation of the Surviving Corporation until thereafter amended as provided
by law and such Articles of Incorporation of the Surviving Corporation;
provided, however, that at the Effective Time the Articles of Incorporation of
the Surviving Corporation shall be amended so that the name of the Surviving
Corporation shall be "Company."

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

     1.5 Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time.

     1.6 Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any action
on the part of Parent, Merger Sub, Company or the holders of any of the
following securities, the following shall occur:

         (a) Conversion of Company Common Stock and Company Preferred Stock. At
the Effective Time, without any action on the part of the holders of the
following securities: (i) each outstanding share of common stock, no par value,
of Company (the "Company Common Stock"), upon the terms and subject to the
conditions set forth below and throughout this Agreement, will be canceled and
extinguished and, pursuant to the terms of Company's articles of incorporation,
shall receive no consideration therefor, and (ii) each outstanding share of
preferred stock, no par value, of Company (the "Company Preferred Stock"), upon
the terms and subject to the conditions set forth below and throughout this
Agreement will be canceled and extinguished and automatically

                                       -2-



converted (subject to Section 1.6(d) and Section 1.6(e)) into the right to
receive: (i) that number of shares of Purchaser Common Stock equal to the Stock
Exchange Ratio (as defined and subject to adjustment as set forth in Section
1.12 hereof) and (ii) the Note Portion (as defined and subject to adjustment as
set forth in Section 1.12 hereof) (the number of shares equal to the Stock
Exchange Ratio and the Note Portion being referred to herein, collectively, as
the "Merger Consideration") upon surrender of the certificate representing such
share of Company Preferred Stock in the manner provided in Section 1.8 (or in
the case of a lost, stolen or destroyed certificate, upon delivery of an
affidavit (and bond, if required) in the manner provided in Section 1.10).

         (b) Treatment of Options. On or prior to the date hereof, the Board of
Directors of Company shall have amended the Company Stock Option Plan, in light
of the structure of the transaction, in which Company will become a wholly-owned
subsidiary of Purchaser, to provide for the cancellation of all Company Options
on and as of the Effective Time due to the following: under Section 12(b) of the
Company Stock Option Plan, in a transaction such as the Merger the Board of
Directors of the Company has the option of either (i) having the Surviving
Corporation assume the Company Options at the exchange ratio applicable to the
Company Common Stock or (ii) accelerating the exercisability of the Company
Options. The election of either option in the preceding sentence would result in
the holders of Company Options receiving nothing upon the exercise of their
respective options. Accordingly, all Company Options would effectively be
cancelled at the Effective Time upon an election of either of the above options
by the Board of Directors of the Company. Promptly after the date hereof, the
Company shall give a notice (the "Cancellation Notice") to all holders of
Company Options, whether or not required under any Company Stock Option Plan or
under any agreements relating to the Company Options, informing such holders of
the foregoing, the form and substance of which shall be subject to the
reasonable review of Purchaser. The Cancellation Notice shall be provided as of
the date of this Agreement.

         (c) Common Stock of Merger Sub. Each share of common stock of Merger
Sub issued and outstanding immediately prior to the Effective Time shall be
converted into and exchanged for one (1) validly issued, fully paid and
non-assessable share of common stock of the Surviving Corporation. Each stock
certificate of Merger Sub evidencing ownership of any such shares shall
thereafter evidence ownership shares of the common stock of the Surviving
Corporation.

         (d) Adjustments to Stock Exchange Ratio. The Stock Exchange Ratio shall
be adjusted to reflect appropriately the effect of any stock split, reverse
stock split, stock dividend (including any dividend or distribution of
securities convertible into Purchaser Common Stock or Company Preferred Stock),
extraordinary cash dividends, reorganization, recapitalization,
reclassification, combination, exchange of shares or other like change with
respect to Purchaser Common Stock or Company Preferred Stock occurring on or
after the date hereof and prior to the Effective Time.

         (e) Fractional Shares. No fraction of a share of Purchaser Common Stock
will be issued by virtue of the Merger, but in lieu thereof each holder of
shares of Company Preferred Stock who would otherwise be entitled to a fraction
of a share of Purchaser Common Stock (after aggregating all fractional shares of
Purchaser Common Stock that otherwise would be received by such holder) shall,
upon surrender of such holder's Certificates(s) (as defined in Section 1.8)
receive from Purchaser an amount of cash (rounded to the nearest whole cent),
without interest, equal to the

                                       -3-



product of (i) such fraction, multiplied by (ii) the average last sale price on
Nasdaq of one share of Purchaser Common Stock for the five (5) most recent days
that Purchaser Common Stock has traded ending on the trading day immediately
prior to the Effective Time, as reported on Nasdaq.

     1.7 Dissenting Shares.

         (a) Notwithstanding any other provisions of this Agreement to the
contrary, any shares of Company Common Stock held by a holder who has not
effectively withdrawn or lost such holder's dissenters' rights under Sections
60.551 through 60.594 of the OBCA ("Dissenting Shares") shall not be converted
into the consideration for Company Common Stock set forth in Section 1.6 hereof
(and subject to the provisions of Article IX hereof), but the holder thereof
shall only be entitled to such rights as are provided by the OBCA.

         (b) Notwithstanding the provisions of Section 1.7(a) hereof, if any
holder of Dissenting Shares shall effectively withdraw or lose (through failure
to perfect or otherwise) such holder's dissenters' rights under the OBCA, then,
as of the later of the Effective Time and the occurrence of such event, such
holder's shares shall automatically be converted into and represent only the
consideration for Company Common Stock set forth in Section 1.6 hereof, without
interest thereon, and subject to the provisions of Section 1.8, upon surrender
of the certificate(s) representing such shares.

         (c) Company shall give Purchaser (i) prompt notice of any written
demand for dissenters' rights received by the Company pursuant to the applicable
provisions of the OBCA, and (ii) the opportunity to direct all negotiations and
proceedings with respect to such demands. The Company shall not, except with the
prior written consent of Purchaser, voluntarily make any payment with respect to
any such demands, offer to settle or settle any such demands.

     1.8 Surrender of Certificates.

         (a) Purchaser to Provide Merger Consideration. At the Effective Time,
Purchaser shall make available for exchange in accordance with this Article I,
the shares of common stock of Purchaser (the "Purchaser Common Stock") and the
Note (as defined in Section 1.12 hereof) issuable pursuant to Section 1.6 in
exchange for outstanding shares of Company Preferred Stock, and cash in an
amount sufficient for payment in lieu of fractional shares pursuant to Section
1.6(e) and any dividends or distributions to which holders of shares of Company
Preferred Stock may be entitled pursuant to Section 1.8(b).

         (b) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Purchaser Common Stock with a record date after the Effective Time
will be paid to the holders of any unsurrendered certificate or certificates of
Company Preferred Stock (the "Certificates") with respect to the shares of
Purchaser Common Stock represented thereby until the holders of record of such
Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Purchaser shall deliver to the
record holders thereof, without interest, certificates representing whole shares
of Purchaser Common Stock issued in exchange therefor along with payment in lieu
of fractional shares pursuant to Section 1.6(e) hereof and the amount of any
such dividends or other

                                       -4-



distributions with a record date after the Effective Time payable with respect
to such whole shares of Purchaser Common Stock.

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

          (d) No Liability. Notwithstanding anything to the contrary in this
Section 1.8, neither the Purchaser nor the Surviving Corporation shall be liable
to a holder of shares of Purchaser Common Stock, Company Common Stock or Company
Preferred Stock for any amount properly paid to a public official pursuant to
any applicable abandoned property, escheat or similar law following the passage
of time specified therein.

     1.9  No Further Ownership Rights in Company Common Stock and Company
Preferred Stock. All shares of Purchaser Common Stock issued in accordance with
the terms hereof (including any cash paid in respect thereof pursuant to Section
1.6(e) and Section 1.8(b)) along with the Note Portion, shall be deemed to have
been issued in full satisfaction of all rights pertaining to such shares of
Company Common Stock and Company Preferred Stock, and there shall be no further
registration of transfers on the records of the Surviving Corporation of shares
of Company Common Stock and Company Preferred Stock which 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 Lost, Stolen or Destroyed Certificates. In the event that any
Certificate(s) shall have been lost, stolen or destroyed, Purchaser shall issue
in exchange for such lost, stolen or destroyed Certificate(s), upon the making
of an affidavit of that fact by the holder thereof, certificate(s) representing
the shares of Purchaser Common Stock into which the shares of Company Preferred
Stock represented by such Certificates were converted pursuant to Section 1.6,
cash for fractional shares, if any, as may be required pursuant to Section
1.6(e) and any dividends or distributions payable pursuant to Section 1.8(b);
provided, however, that Purchaser may, in its sole and absolute discretion and
as a condition precedent to the issuance of such certificates representing
shares of Purchaser Common Stock, cash and other distributions, 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 Purchaser or the Surviving Corporation with respect to the
Certificate(s) alleged to have been lost, stolen or destroyed.

               (ii)   Purchaser may dispute any amounts reflected on the Closing

such other accounting firm being referred to herein as the "Independent
Accounting Firm"), which shall, within thirty (30) business days after such
submission, determine and report to the Purchaser and Parent upon such remaining
disputed items, and such report shall be final, binding and conclusive on
Purchaser and Parent. The fees and disbursements of the Independent Accounting

Firm that is unsuccessfully disputed by each such party (as finally determined
by the Independent Accounting Firm) bears to the total amount of such remaining
disputed items so submitted.

               (iii)  In acting under this Agreement, the Purchaser's
Accountants, the Parent's Accountants and the Independent Accounting Firm shall
be entitled to the privileges and immunities of arbitrators.

               (iv)   Adjustment. The Closing Balance Sheet shall be deemed
final for the purposes of this Section 1.15 upon the earliest of (A) the failure
of the Purchaser to notify Parent of a dispute within ten (10) business days of
Parent's delivery of the Closing Balance Sheet to Purchaser, (B) the resolution
of all disputes, pursuant to Section 1.15(b)(ii), by Purchaser and Parent and
(C) the resolution of all disputes, pursuant to Section 1.15(b)(ii), by the
Independent Accounting Firm. "Actual Company Net Book Value" means the net book
value of Company as of the Effective Time after giving effect to (A), (B) and
(C) minus the Book Value Adjustments. Within three (3) business days of the
Closing Balance Sheet being deemed final, an adjustment to the principal amount
of the Note shall be made as follows: in the event that the Estimated Net Book
Value differs from the Actual Company Net Book Value as reflected on the Closing
Balance Sheet, then the principal amount of the Note shall be adjusted upward or
downward, as the case may be, in an amount equal to such difference (the "PNV
Adjustment"). Purchaser shall deliver written notice to Parent specifying the
amount thereof, which adjustment shall be automatically made in the amount of
the difference.

     1.16 The Stock Portion Adjustment. The Stock Portion is subject to
adjustment as follows: if any adjustment pursuant to Section 1.13 or Section
1.15 exceeds the principal balance of the Note, then the Stock Portion shall be
reduced by such difference, and Parent shall return the number of shares of
Purchaser Common Stock equal to such difference divided by the Average Purchaser
Stock Price (the "Stock Portion Adjustment") to Purchaser within three (3)
business days of receipt of written notice of such Stock Portion Adjustment by
Purchaser. No failure of Purchaser to deliver a notice of the type specified in
the immediately preceding sentence shall relieve Parent of the obligation
created by any Stock Price Adjustment owed to Purchaser.

other documents with the SEC.

            (b)    Each set of consolidated financial statements (including, in
each case, any related notes thereto) contained in the Purchaser SEC Reports was
prepared in accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto or, in the
case of unaudited statements, do not contain footnotes as permitted by Form 10-Q
of the Exchange Act) and each presented fairly in all material respects the
consolidated financial position of Purchaser and its subsidiaries at the
respective dates thereof and the consolidated results of its operations and cash

statements were or are subject to normal adjustments which were not or are not
expected to be material in amount.

            (c)    Since the date of the balance sheet included in Purchaser's
report on Form 10-Q filed on July 26, 2002, and until the date hereof, there has

no liabilities or obligations of any nature (whether accrued,

                                      -31-



absolute, contingent or otherwise) that would be required to be reflected on a
balance sheet or in notes thereto prepared in accordance with GAAP, except (i)
liabilities incurred since June 30, 2002 in the ordinary course of business; or
(ii) liabilities which would not reasonably be expected to have a Material
Adverse Effect of Purchaser.

     4.9    Absence of Litigation. Except as set forth in Section 4.9 of the
Purchaser Schedule and in the Purchaser SEC Reports, there are no claims,
actions, suits or proceedings pending or, to the knowledge of Purchaser,
threatened (or, to the knowledge of Purchaser, any governmental or regulatory
investigation pending or threatened) against Purchaser or any properties or
rights of Purchaser, before any court, arbitrator or administrative,
governmental or regulatory authority or body, domestic or foreign, except as
would not reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect on Purchaser.

Merger Sub have, as of the date of this Agreement unanimously (i) approved this
Agreement and the transactions contemplated hereby and (ii) determined that the

Schedule, neither Purchaser, Merger Sub nor any other subsidiary of Purchaser is

bound or affected, or (ii) any material note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Purchaser, Merger Sub or any other subsidiary of Purchaser
is a party or by which Purchaser, Merger Sub or any other subsidiary of
Purchaser or its or any of their respective properties is bound or affected,
except for any conflicts, defaults or violations that (individually or in the
aggregate) would not cause the Purchaser to lose any material benefit or incur
any material liability. No investigation or review by any governmental or
regulatory body or authority is pending or, to the knowledge of Purchaser,
threatened against Purchaser, Merger Sub or any other subsidiary of Purchaser,
nor has any Governmental Entity indicated to the Purchaser an intention to
conduct the same, other than, in each such case, those the outcome of which
could not, individually or in the aggregate, reasonably be expected to have the
effect of prohibiting or materially impairing any business practice of the
Purchaser, Merger Sub or any other subsidiary of Purchaser, any acquisition of
material property by the Purchaser, Merger Sub or any other subsidiary of
Purchaser or the conduct of business by the Purchaser, Merger Sub or any other

     6.6  Employee Benefits.

          (a)  Purchaser shall provide or cause to be provided that under each
employee benefit plan, policy, program or arrangement where service is relevant
to a determination of an employee's eligibility to participate, vesting, or
level or amount of benefits, employees of Company shall be credited with their
periods of service with Company and its affiliates prior to the Closing
(excluding employee benefit plans, policies, programs or arrangements that
provide for retirement benefits or sabbatical leave); provided, that employees
of Company shall be credited with their periods of service with Company only
(and not with Parent or any of its other affiliates) prior to Closing for
employee benefit plans, policies, programs or arrangements that provide for
severance pay, and provided further, that Parent provides Company with all
applicable accurate records to facilitate such credits. Purchaser shall make its
commercially reasonable best efforts available, or cause to be made available,
to employees of Company, medical, dental, disability and other welfare benefits
plans and programs without regard to any preexisting condition limitation,
actively-at-work requirement or similar limitation to the extent that such
employee had satisfied any similar limitation or requirement under an analogous
Employee Plan prior to the Effective Time. In determining an employee's share of
the cost of coverage under any plan or program of Purchaser or its subsidiaries
for the coverage year in which the Closing Date falls, the Purchaser shall make
its commercially best efforts to cause the employee to be credited with any
pre-Closing co-pays and payment of deductibles toward any cost of coverage under
corresponding Employee Plans that cover the employee for the remainder of such
coverage year, provided that Purchaser receives evidence reasonably satisfactory
to Purchaser from Parent, Company or Employees to facilitate such credits. For a
period beginning on the Closing Date and ending no earlier than the first
anniversary of the Closing Date, Purchaser or its affiliates shall provide to
employees of the Company and its affiliates who continue employment with
Purchaser or any of its affiliates (i) benefits that are substantially similar,
in the aggregate, to the benefits provided to such employees immediately prior
to the Closing Date, (ii) benefits that are substantially similar, in the
aggregate, to the benefits offered to similarly situated employees of Purchaser,
or (iii) a combination of clauses (i) and (ii). Options to purchase common stock
of the Purchaser will be granted to employees of Company, other than
Transitional Employees (as defined herein), who continue employment with
Purchaser or its subsidiaries promptly following the Effective Time with a per
share exercise price equal to one hundred percent of the fair market value of
the Purchaser's common stock on the date of grant and subject to the vesting
schedule as determined by Purchaser.

          (b)  Effective not later than the Effective Time, Company shall cease
to participate in those Employee Plans (the "Parent-group Employee Plans") (i)
in which it participated prior to the Effective Time, and (ii) which were not
sponsored or maintained by Company solely for the benefit of its Employees,
former Employees or beneficiaries. Prior to Closing, Parent shall furnish
Purchaser with a list and copies of relevant documents of all Employee Plans
other than Parent-group Employee Plans. Upon and following the Effective Time,
Company shall have no liability for contributions, premiums, benefits, or other
payments, or any other obligation, under any Parent-group Employee Plan.

                                      -38-



          (c)  Parent and Company or its Affiliates shall take all actions
necessary or appropriate so that effective no later than immediately prior to
the Effective Time, Parent or any of its ERISA Affiliates (other than the
Company and subsidiaries of the Company) shall become the sole sponsor of the
401(k) Plan maintained by Company for the benefit of its Employees (the "Company
401(k) Plan"). On and after the Effective Time, Purchaser, Company and their
affiliates shall have no liability with respect to the Company 401(k) Plan.
Purchaser, Parent and Company agree that the Merger will result in, and
constitute, a distribution event for the Employees under the Company 401(k)
Plan. Parent and Company further agree that on or prior to the Closing Date, all
accounts of Employees participating in the Company 401(k) Plan shall be fully
vested. To the extent permitted by the Purchaser's 401(k) plan, Purchaser shall
cause a tax-qualified defined contribution plan maintained by Purchaser or a
subsidiary of Purchaser to accept rollovers (including direct rollovers) from
the Company 401(k) Plan in respect of distributions made on account of the
transactions contemplated by this Agreement; provided, however, Purchaser is
reasonably satisfied that the Company 401(k) Plan is qualified under Code
Section 401(a) and that the trust is exempt under Code Section 501(a).

          (d)  Parent assumes any and all liability relating to, arising out of,
or resulting from COBRA (or similar state statute) attributable to Employees and
any and all related Qualified Beneficiaries (as such term is defined in COBRA)
with respect to qualifying events occurring at or prior to the Effective Time
(including, without limitation, by reason of the transactions contemplated by
this Agreement) under an Employee Plan. Company shall cooperate with an
administrator identified by Parent in facilitating the delivery by the
administrator of required notices and other COBRA-related communications to
Employees and Qualified Beneficiaries.

          (e)  Purchaser agrees to accept sponsorship of flexible spending
accounts (pursuant to Code Sections 105 and 129) of Employees and maintain such
accounts in accordance with their terms for the remainder of the plan year.
Parent shall make its commercially reasonable best efforts to transfer to
Purchaser all records attributable to each Employee's participation in the
flexible spending accounts maintained by Parent or Company; and the aggregate
cash amount of contributions paid by or on behalf of Employees to, net of the
aggregate amount of reimbursements and payments to Employees from, such flexible
spending accounts for the year in which the Closing occurs. Purchaser shall be
responsible for filing Forms 5500 as may be required for any flexible spending
account transferred to Purchaser and Parent shall cooperate with reasonable
requests for information necessary to complete such Forms 5500.

     6.7  Third Party Consents. As soon as practicable following the date
hereof, Purchaser, Parent and Company will each use its commercially reasonable
efforts to obtain any consents, waivers and approvals under any of its or its
subsidiaries' respective agreements, contracts, licenses or leases required to
be obtained in connection with the consummation of the transactions contemplated
hereby.

     6.8  Non-Competition.

          (a)  Parent agrees that for a period of three (3) years after the

controlled Affiliate) controls, including any entity acquired subsequent to the
date hereof (Parent and each such entity a "Restricted Entity") shall not make,
have made, use, sell or otherwise distribute, develop, have developed, and shall
not manufacture for its own behalf or on behalf of another Restricted Entity,
equipment, services and/or technology for generation, processing and delivery of

security (the "Restricted Products"); and Parent further agrees that for a
period of three (3) years no Restricted Entity may manufacture, distribute,
market, sell or resell for its own behalf or on behalf of another Restricted
Entity any Restricted Products.

          (b)  Parent agrees that for a period of three (3) years after the

accounted for greater than thirty-three percent (33%) of such entity's revenues
during the previous year; (y) is projected to account for greater than
thirty-three percent (33%) of such entity's revenues during the next year; or
(z) would have accounted for greater than ten percent (10%) of Parent's revenues
during the previous year (a "Relevant Acquisition"). Any acquisition by Parent
or another Restricted Entity for whom the sale of Restricted Products is below
the levels specified in subclauses (x), (y) or (z) shall be a "Permitted
Acquisition" for purposes of this Section 6.8.

     A Restricted Entity may make a Relevant Acquisition if, and only if, (i) it
is making such Relevant Acquisition by itself and not as part of a group that
includes a person described in subclause (x), (y) or (z), (ii) its primary
purpose in making such Relevant Acquisition is not to exploit for profit such
Restricted Products, or (iii) (A) the Restricted Entity has a good faith intent
to dispose of (or cease operating) the entity or portion thereof whose business
constituted the manufacture or sale of Restricted Products within six months of
the consummation of such Relevant Acquisition and Restricted Entity completes
such disposal or cessation within a commercially reasonable time after
consummation of the Relevant Transaction, and (B) in connection with such
disposition Parent grants Purchaser the right or option to acquire such entity
or portion in any sale or disposition process that Parent may conduct. For the
purpose of determining whether an acquisition is a Relevant Acquisition or a
Permitted Acquisition, all entities previously acquired under the Permitted
Acquisition exception shall be included in the person proposed to be acquired.
All restrictions specified in this Section 6.8 shall not apply to any person who
purchases more than 50% of the voting common stock of Parent or more than 50% of
Parent's assets (a "Change of Control") and shall not apply to Parent or any
Restricted Entity after such Change of Control if Parent discontinues using its
brand name in business or legally ceases to exit.

     Nothing in this Section 6.8 shall be construed as prohibiting any
Restricted Entity from using underlying technology or components of Restricted
Products in unrelated fields.

     For the purposes of this Section 6.8, "control" means the ability (through
the ownership of securities or similar interests, by contract or otherwise and
whether or not exercised) to elect a majority of the board of directors or
similar governing body of a Person.

contemplated by this Agreement. Parent agrees not to transfer any Company
Preferred Stock from the date of this Agreement through the Effective Time.
Parent hereby covenants and agrees to execute and deliver any additional
documents, and to take any additional actions, necessary or desirable, in the
reasonable opinion of Purchaser, to carry out the intent of this Section 6.11.

(including, without limitation, reasonable attorneys' and consultants' fees and
expenses) actually suffered or incurred by them (hereinafter a "Loss"), arising
out of or resulting from:

             (i)    the breach of any representation or warranty made by Company
and Parent contained in the Acquisition Documents (which, for the purposes
hereof, shall include the bring down thereof included in the certificate
referenced in Section 7.3(a)), (other than a breach of any representation and
warranty if such breach is the result of (A) the exercise of any Company Option
after the Effective Time or the treatment of Company Options or the amendment of
the Company Option Plan pursuant to Section 1.6(b) hereof or (B) a breach of the
representation and warranty contained in Section 2.7 relating to the treatment
of the items comprising the Book Value Adjustments or the accounts receivable
referred to in subsection (iv) below in the Company Reports, for which Parent
shall have no liability;) or

             (ii)   the breach of any covenant or agreement by the Company and
Parent contained in the Acquisition Documents; or

             (iii)  payments by the Company to holders of Company Common Stock

with the repurchase of such stock; or

             (iv)   to the extent the Surviving Corporation has been unable to
collect, using commercially reasonable efforts, the two accounts receivable set
forth on Schedule 9.2 hereto, and, in the case of the receivable from Advanced

             (v)    any taxes due and payable under Article VIII hereto; or

             (vi)   payments associated with Dissenting Shares, or any amount
associated with Dissenting Shares.

         For the purposes of determining whether there has been a breach of any
representation or warranty made by Company or Parent, all "Material Adverse

similar phrases shall be disregarded and all

                                      -51-



qualifications based on "knowledge" other than in the case of threatened
litigation or governmental proceedings shall also be disregarded.

     To the extent that the undertakings of Parent set forth in this Section 9.2
may be unenforceable, Parent shall contribute the maximum amount that it is
permitted to contribute under applicable law to the payment and satisfaction of
all Losses incurred by Purchaser, Company and the Subsidiaries.

         (b) A Purchaser Indemnified Party shall give the Parent notice of any
matter which a Purchaser Indemnified Party has determined has given or could
give rise to a right of indemnification under this Agreement, within sixty (60)
days of such determination, stating the amount of the Loss, if known, and method
of computation thereof, and containing a reference to the provisions of this
Agreement in respect of which such right of indemnification is claimed or
arises. The obligations and Liabilities of Parent under this Article IX with
respect to Losses arising from claims of any third party which are subject to
the indemnification provided for in this Article IX ("Third Party Claims") shall
be governed by and contingent upon the following additional terms and
conditions: if a Purchaser Indemnified Party shall receive notice of any Third
Party Claim, the Purchaser Indemnified Party shall give Parent notice of such
Third Party Claim within thirty (30) days of receipt by the Purchaser
Indemnified Party of such notice; provided, however, that the failure to provide
such notice shall not release Parent from any of its obligations under this
Article IX except to the extent Parent is materially prejudiced by such failure
and shall not relieve Parent from any other obligation or Liability that it may
have to any Purchaser Indemnified Party otherwise than under this Article IX. If
Parent acknowledges in writing its obligation to indemnify the Purchaser
Indemnified Party hereunder against any Losses that may result from such Third
Party Claim, then Parent shall be entitled to assume and control the defense of
such Third Party Claim at its expense and through counsel of its choice if it
gives notice of its intention to do so to the Purchaser Indemnified Party within
ten (10) days of the receipt of such notice from the Purchaser Indemnified
Party; provided, however, that if there exists or is reasonably likely to exist
a conflict of interest that would make it inappropriate in the judgment of the
Indemnified Party, in its sole and absolute discretion, for the same counsel to
represent both the Purchaser Indemnified Party and Parent, then the Purchaser
Indemnified Party shall be entitled to retain its own counsel, in each
jurisdiction for which the Purchaser Indemnified Party determines counsel is
required, at the expense of Parent. In the event Parent exercises the right to
undertake any such defense against any such Third Party Claim as provided above,
the Purchaser Indemnified Party shall cooperate with Parent in such defense and
make available to Parent, at Parent's expense, all witnesses, pertinent records,
materials and information in the Indemnified Party's possession or under the
Purchaser Indemnified Party's control relating thereto as is reasonably required
by Parent. Similarly, in the event the Purchaser Indemnified Party is, directly
or indirectly, conducting the defense against any such Third Party Claim, Parent
shall cooperate with the Purchaser Indemnified Party in such defense and make
available to the Purchaser Indemnified Party, at Parent's expense, all such
witnesses, records, materials and information in Parent's possession or under
Parent's control relating thereto as is reasonably required by the Purchaser
Indemnified Party. No such Third Party Claim may be settled by the Parent
without the prior written consent of the Purchaser Indemnified Party.

     9.3 Limits on Parent Indemnification. Notwithstanding anything to the
contrary contained in this Agreement, the maximum amount of indemnifiable Losses
which may be recovered

                                      -52-



from the Parent arising out of or resulting from the causes enumerated in
Section 9.2(a) shall be an amount equal to twenty-five percent of the Initial
Note Face Value; provided, however, that such limitation shall not apply to Tax
Matters covered by Article VIII. No claim may be made by the Purchaser with
respect to indemnifiable Losses until the aggregate of all indemnifiable Losses
exceeds $200,000, and Seller shall not be obligated with respect to indemnified
Losses below such threshold; provided that this limitation will not apply for
Losses arising under Sections 9.2(a)(iii) through (vi).

     9.4  Reduction in Principal Amount of Note. A Purchaser Indemnified Party's
sole remedy in the event of an acknowledgment or determination of liability by
Parent with respect to an indemnification claim under Section 9.2 (other than a
claim under Section 9.2(a)(v)) is to reduce the outstanding principal amount of
the Note by the amount of such claim, subject to the limitations set forth in
Section 9.3. Interest shall thereafter accrue on the remaining principal balance
of the Note after giving effect to such reduction. Such reduction may be
effected from time to time upon each concession or determination of liability
pursuant to the terms hereof, and Purchaser shall record on its records the date
and amount of each such reduction. If any reduction is made hereunder for
indemnification for which the Purchaser Indemnified Party could have collected
on a claim (a "Pass-Through Claim") against a third party, Parent shall be
subrogated to all rights and interests of the Purchaser Indemnified Party and
any of its successors, to pursue and to collect on any indemnification or other
remedy available to the Purchaser Indemnified Party with respect to a
Pass-Through Claim.

     9.5  Indemnification by the Purchaser.

          (a)  Parent and its Affiliates, officers, directors, employees,
agents, successors and assigns (each a "Parent Indemnified Party") shall be
indemnified and held harmless by the Purchaser for any and all Losses arising
out of or resulting from:

               (i)    the breach of any representation or warranty made by
Purchaser and Merger Sub contained in the Acquisition Documents (which, for the
purposes hereof, shall include the bring down thereof included in the
certificate referenced in Section 7.2(a)); or

               (ii)   the breach of any covenant or agreement by Purchaser and
Merger Sub contained in the Acquisition Documents; or

               (iii)  any liability resulting from the exercise of any Company
Option after the Effective Time or the treatment of Company Options or the
amendment of the Company Option Plan pursuant to Section 1.6(b) hereof.

     For the purposes of determining whether there has been a breach of any
representation or warranty made by Purchaser and Merger Sub, all "Material
Adverse Effect" qualifications and other qualifications based on the word
material or similar phrases shall be disregarded and all qualifications based on
"knowledge" other than in the case of threatened litigation or governmental
proceedings shall also be disregarded.

                                      -53-



     To the extent that the undertakings of Purchaser set forth in this Section
9.5 may be unenforceable, Purchaser shall contribute the maximum amount that it
is permitted to contribute under applicable law to the payment and satisfaction
of all Losses incurred by Parent.

          (b)  A Parent Indemnified Party shall give Purchaser notice of any
matter which a Parent Indemnified Party has determined has given or could give
rise to a right of indemnification under this Agreement, within sixty (60) days
of such determination, stating the amount of the Loss, if known, and method of
computation thereof, and containing a reference to the provisions of this
Agreement in respect of which such right of indemnification is claimed or
arises. The obligations and Liabilities of the Purchaser under this Article IX
with respect to Losses arising from Third Party Claims shall be governed by and
contingent upon the following additional terms and conditions: if a Parent
Indemnified Party shall receive notice of any Third Party Claim, the Parent
Indemnified Party shall give Purchaser notice of such Third Party Claim within
thirty (30) days of the receipt by the Parent Indemnified Party of such notice;
provided, however, that the failure to provide such notice shall not release
Purchaser from any of its obligations under this Article IX except to the extent
Purchaser is materially prejudiced by such failure and shall not relieve
Purchaser from any other obligation or Liability that it may have to any Parent
Indemnified Party otherwise than under this Article IX. If Purchaser
acknowledges in writing its obligation to indemnify the Parent Indemnified Party
hereunder against any Losses that may result from such Third Party Claim, then
Purchaser shall be entitled to assume and control the defense of such Third
Party Claim at its expense and through counsel of its choice if it gives notice
of its intention to do so to the Parent Indemnified Party within ten (10) days
of the receipt of such notice from the Parent Indemnified Party; provided,
however, that if there exists or is reasonably likely to exist a conflict of
interest that would make it inappropriate in the judgment of the Parent
Indemnified Party, in its sole and absolute discretion, for the same counsel to
represent both the Parent Indemnified Party and Purchaser, then the Parent
Indemnified Party shall be entitled to retain its own counsel, in each
jurisdiction for which the Parent Indemnified Party determines counsel is
required, at the expense of Purchaser. In the event Purchaser exercises the
right to undertake any such defense against any such Third Party Claim as
provided above, the Parent Indemnified Party shall cooperate with Purchaser in
such defense and make available to the Purchaser, at the Purchaser's expense,
all witnesses, pertinent records, materials and information in the Parent
Indemnified Party's possession or under the Parent Indemnified Party's control
relating thereto as is reasonably required by Purchaser. Similarly, in the event
the Parent Indemnified Party is, directly or indirectly, conducting the defense
against any such Third Party Claim, Purchaser shall cooperate with the Parent
Indemnified Party in such defense and make available to the Parent Indemnified
Party, at Purchaser's expense, all such witnesses, records, materials and
information in Purchaser's possession or under Purchaser's control relating
thereto as is reasonably required by the Parent Indemnified Party. No such Third
Party Claim may be settled by Purchaser without the prior written consent of the
Parent Indemnified Party.

     9.6  Limits on Purchaser Indemnification. Notwithstanding anything to the
contrary contained in this Agreement, the maximum amount of indemnifiable Losses
which may be recovered from Purchaser arising out of or resulting from the
causes enumerated in Section 9.5(a) shall be equal to twenty-five percent of the
Initial Note Face Value. No claim may be made by Parent with respect to
indemnifiable Losses until the aggregate of all indemnifiable Losses exceeds
$200,000, and Purchaser shall not be obligated with respect to indemnified
Losses below such threshold; provided that there shall be no threshold for any
Loss under Section 9.5(a)(iii) hereof.

                                      -54-



     9.7  Exclusive Rights. An indemnified party's rights to indemnification
under this Article IX, including the right to reduction contained in Section
9.4, are the sole rights in the event of a breach of any representation,
warranty, covenant or agreement contained in the Acquisition Documents except
any Loss as a result of fraud shall not be limited in any way by this Article
IX.

                                   ARTICLE X

                        TERMINATION, AMENDMENT AND WAIVER

     10.1 Termination. This Agreement may be terminated at any time prior to the
Effective Time:

          (a)  by mutual written consent of Purchaser and Parent;

          (b)  by either Company or Purchaser if the Merger shall not have been
consummated by December 31, 2002 for any reason; provided, however, that the
right to terminate this Agreement under this Section 10.1(b) shall not be
available to any party whose action or failure to act has been a principal cause
of or resulted in the failure of the Merger to occur on or before such date and
such action or failure to act constitutes a breach of this Agreement;

          (c)  by either Company or Purchaser if a Governmental Entity shall
have issued an order, decree or ruling or taken any other action, in any case
having the effect of permanently restraining, enjoining or otherwise prohibiting
the Merger, which order, decree, ruling or other action is final and
nonappealable;

          (d)  by Company, upon a breach of any representation, warranty,
covenant or agreement on the part of Purchaser set forth in this Agreement, or
if any representation or warranty of Purchaser shall have become untrue, in
either case such that the conditions set forth in Section 7.2(a) or Section
7.2(b) would not be satisfied as of the time of such breach or as of the time
such representation or warranty shall have become untrue, provided, that if such
inaccuracy in Purchaser's representations and warranties or breach by Purchaser
is curable by Purchaser through the exercise of its commercially reasonable
efforts, then Company may not terminate this Agreement under this Section
10.1(d) for thirty (30) days after delivery of written notice from Company to
Purchaser of such breach, provided Purchaser continues to exercise commercially
reasonable efforts to cure such breach (it being understood that Company may not
terminate this Agreement pursuant to this Section 10.1(d) if it shall have
materially breached this Agreement or if such breach by Purchaser is cured
during such thirty (30) day period); or

          (e)  by Purchaser, upon a breach of any representation, warranty,
covenant or agreement on the part of Company set forth in this Agreement, or if
any representation or warranty of Company shall have become untrue, in either
case such that the conditions set forth in Section 7.3(a) or Section 7.3(b)
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided, that if such
inaccuracy in Company's representations and warranties or breach by Company is
curable by Company through the exercise of its commercially reasonable efforts,
then Purchaser may not terminate this Agreement under this Section 10.1(e) for
thirty (30) days after delivery of written notice from Purchaser to

                                      -55-



Company of such breach, provided Company continues to exercise commercially
reasonable efforts to cure such breach (it being understood that Purchaser may
not terminate this Agreement pursuant to this Section 10.1(e) if it shall have
materially breached this Agreement or if such breach by Company is cured during
such thirty (30) day period).

     10.2 Notice of Termination; Effect of Termination. Any termination of this
Agreement under Section 10.1 above will be effective immediately upon (or, if
the termination is pursuant to Section 10.1(d) or Section 10.1(e) and the
proviso therein is applicable, thirty (30) days after) the delivery of written
notice of the terminating party to the other parties hereto. In the event of the
termination of this Agreement as provided in Section 10.1, this Agreement shall
be of no further force or effect, except (i) as set forth in this Section 10.2,
Section 10.3 and Article XI (General Provisions), each of which shall survive
the termination of this Agreement, and (ii) nothing herein shall relieve any
party from liability for any intentional or willful breach of this Agreement. No
termination of this Agreement shall affect the obligations of the parties
contained in the Confidentiality Agreement, all of which obligations shall
survive termination of this Agreement in accordance with their terms.

     10.3 Fees and Expenses. Except as set forth in this Section 10.3, all fees
and expenses incurred in connection with this Agreement and the transactions
contemplated hereby by Purchaser shall be paid by Purchaser whether or not the
Merger is consummated and all fees and expenses incurred in connection with this
Agreement and the transactions contemplated hereby by Parent and Company shall
be paid by Parent whether or not the Merger is consummated.

     10.4 Amendment. Subject to applicable law, 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 Purchaser, Parent and Company.

     10.5 Extension; Waiver. At any time prior to the Effective Time, any party
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties 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. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

            (a)    When a reference is made in this Agreement to Exhibits, such
reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be
to a Section of this Agreement. Unless otherwise indicated the words "include,"
"includes" and "including" when 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. When reference is
made herein to "the business of" an entity, such reference shall be deemed to
include the business of all direct and indirect subsidiaries of such entity.
Reference to the subsidiaries of an entity shall be deemed to include all direct
and indirect subsidiaries of such entity.

            (b)    For purposes of this Agreement, the term "Material Adverse
Effect" when used in connection with an entity means any change, event,
violation, inaccuracy, circumstance or effect, individually or when aggregated
with other changes, events, violations, inaccuracies, circumstances or effects,
that is materially adverse to the business, assets (including intangible
assets), capitalization, financial condition or results of operations of such
entity and its subsidiaries taken as a whole, other than changes, events,
circumstances or effects arising out of general business or economic conditions
or generally affecting the industry in which the party is engaged and not
disproportionately adversely affecting such party or business; provided that a
decline in a Person's stock price shall not in and of itself constitute a
Material Adverse Effect.

            (c)    For purposes of this Agreement, the term "Person" shall mean
any individual, corporation (including any non-profit corporation), general
partnership, limited partnership, limited liability partnership, joint venture,
estate, trust, company (including any limited liability company or joint stock

counterparts have been signed by each of the parties and delivered to the other
party, it being understood that all parties need not sign the same counterpart.

     11.4   Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Schedule, the
Parent Schedule and the Purchaser Schedule (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings, both written and oral, among the parties

Closing and shall survive any termination of this Agreement; and (b) are not
intended to confer upon any other person any rights or remedies hereunder.

     11.5   Severability. In the event that any provision of this Agreement, or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

     11.6   Other Remedies; Specific Performance. Except as otherwise provided
herein, including without limitation the limitations contained in Section 9.7,
any and all remedies herein expressly conferred upon a party will be deemed
cumulative with and not exclusive of any other remedy conferred hereby, or by
law or equity upon such party, and the exercise by a party of any one remedy
will not preclude the exercise of any other remedy. The parties hereto agree
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the parties shall be
entitled to seek an injunction or injunctions to prevent breaches of this

accordance with the laws of the State of Oregon, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

     11.8   Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

     11.9   Assignment. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

     11.10  WAIVER OF JURY TRIAL. EACH OF PARENT, COMPANY, PURCHASER AND MERGER
SUB HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION,

ENFORCEMENT HEREOF.

                                      -60-

without giving effect to the transactions contemplated by the Merger Agreement,
neither Parent nor any Controlled Affiliate of Parent beneficially owns any
Voting Securities of Purchaser.

                                       B-3



     2.2 Standstill Provisions. Parent shall not acquire, directly or
indirectly, and shall not cause or permit any Controlled Affiliate of Parent to
acquire, directly or indirectly (through market purchases or otherwise), record
or beneficial ownership of any Voting Securities of Purchaser without the prior
written consent of the Board of Directors of Purchaser; provided, however, that
the prior written consent of the Board of Directors of Purchaser shall not be
required for the acquisition of any Voting Securities of Purchaser directly from
Purchaser or resulting from a stock split, stock dividend or similar
recapitalization by Purchaser. Nothing contained in this Section 2.2 shall
adversely affect any right of Parent or any Controlled Affiliate of Parent to
acquire record or beneficial ownership of Voting Securities of Purchaser
pursuant to any rights plan instituted by Purchaser.

     2.3 Voting. Unless the Board of Directors of Purchaser otherwise consents
in writing in advance, Parent shall take such action (and shall cause each
Controlled Affiliate of Parent that beneficially owns Voting Securities of
Purchaser to take such action) as may be required so that all Voting Securities
of Purchaser beneficially owned by Parent (or any such Controlled Affiliate of
Parent) from time to time, other than the Base Shares, are voted on all matters
to be voted on by holders of Voting Securities of Purchaser in the same
proportion (for, against and abstain, with lost, damaged or disfigured ballots
counting as abstentions to the extent that they cannot be counted as for or
against under applicable law) as the votes cast by the other holders of Voting
Securities of Purchaser with respect to such matters ("Proportionately"). At the
written request of Purchaser furnished to Parent between 10 and 30 days prior to
a shareholders meeting, Parent (or any Controlled Affiliate of Parent), as the
holder of Voting Securities of Purchaser, shall be present, in person or by
proxy, at all meetings of the stockholders of Purchaser so that all Voting
Securities of Purchaser beneficially owned by Parent (or such Controlled
Affiliate of Parent) from time to time may be counted for the purposes of
determining the presence of a quorum at such meetings. The foregoing provision
shall also apply to the execution by Parent of any written consent in lieu of a
meeting of holders of Voting Securities of Purchaser or any class thereof.

     2.4 Voting Trust. Parent shall not, and shall not cause or permit any
Controlled Affiliate of Parent to, deposit any Voting Securities of Purchaser in
a voting trust or, except as otherwise provided herein, subject any Voting
Securities of Purchaser to any arrangement or agreement with respect to the
voting of such Voting Securities of Purchaser.

approved in writing in advance by the Board of Directors of Purchaser except
that:

          (a) Parent may transfer the Securities subject to Section 3.3(a)
below, to any Controlled Affiliate of Parent, so long as such Controlled
Affiliate agrees in writing, in form reasonably acceptable to counsel for
Purchaser, to hold such Securities subject to all the provisions of this
Agreement, and so agrees to transfer such Voting Securities to Parent or another

                                       B-5



          (b) Parent may transfer the Securities in response to any general

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
          FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE

          OF COUNSEL SATISFACTORY TO THE ISSUER AS TO THE AVAILABILITY
          OF AN EXEMPTION FROM REGISTRATION.

     3.3  Procedures for Certain Transfers.

          (a) In connection with any transfer of any Securities pursuant to
Sections 3.1(a), (b) or (c) hereof, Parent shall provide the Purchaser with
evidence reasonably satisfactory to Purchaser and its counsel that the
transaction may be effected without registration under the Securities Act, which
may include: (i) a written opinion of legal counsel (including in-house
counsel), who shall be reasonably satisfactory to Purchaser, addressed to
Purchaser and reasonably satisfactory in form and substance to Purchaser's
counsel, to the effect that the proposed transfer of the Securities may be
effected without registration under the Securities Act; or (ii) a "no action"
letter from the SEC and a copy of any request by Parent (together with all
supplements or amendments thereto), which shall have been provided to Purchaser
at or prior to the time of first delivery to the SEC's staff, to the effect that
the transfer of such Securities without registration will not result in a
recommendation by the staff of the SEC that action be taken with respect
thereto, whereupon Parent shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered by Parent to
Purchaser.

          (b) In connection with any proposed transfer of Securities pursuant to
Rule 144, Parent shall comply with the reasonable requirements of Purchaser's
transfer agent with respect to sales of restricted securities pursuant to Rule
144.

          (c) Each certificate evidencing the Securities transferred (other than
a transfer pursuant to a registration statement) shall bear the restrictive
legend set forth in Section 3.2, except that such certificate shall not bear
such restrictive legend if: (i) in the opinion of counsel for Purchaser, such
legend is not required in order to establish compliance with any provisions of
the Securities Act; (ii) the Securities have been held by the holder for more
than two years, and the holder represents to counsel for Purchaser that it has
not been an "Affiliate" (as such term is defined

                                       B-6



for purposes of Rule 144) of Purchaser during the three-month period prior to
the sale and shall not become an affiliate (as such term is defined for purposes
of Rule 144) of Purchaser without resubmitting the Securities for reimposition
of the legend; or (iii) the Securities have been sold pursuant to Rule 144 or
pursuant to an effective registration statement. The restrictive legend
specified in Section 3.2 shall promptly be removed in connection with a sale
pursuant to a registration statement or the satisfaction of subclause (i), (ii)
or (iii) above.

     3.4 Covenant Regarding Exchange Act Filings. With a view to making

to sell securities of Purchaser to the public without registration. Purchaser
agrees to:

              (i)   Make and keep public information available, as those terms
are its understood and defined in SEC Rule 144;

              (ii)  File with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the Exchange Act; and

              (iii) Furnish to Parent, so long as Parent owns any Voting
Securities, forthwith upon request (i) a written statement by Purchaser that it
has complied with the reporting requirements of SEC Rule 144; (ii) a copy of the
most recent annual or quarterly report of Purchaser and such other reports and
documents so filed by Purchaser and (iii) such other information as may be
reasonably requested in availing Parent of any rule or regulation of the SEC
which permits the selling of any such securities without registration.

     3.5  First Refusal.

          (a) Notice of Transfer. If after _________, 2003 [first year after
Effective Date] and before _________, 2004 [two years from Effective Date]
Parent proposes to transfer any Securities to a Purchaser Competitor in a
private transaction or in a negotiated block trade on an exchange or in an over
the counter market, then Parent shall promptly give written notice (the
"Notice") to the Purchaser as described in this Section 3.5. The Notice shall
indicate the number of Securities to be transferred, the consideration to be
paid, and the name of each prospective purchaser or transferee. Parent shall not
consummate any such proposed Transfer prior to the satisfaction of the
applicable notice periods described herein.

          (b) Purchaser Right of First Refusal. For a period of five (5) days
following receipt of any Notice described in Section 3.5(a), Purchaser shall
have the right to purchase all (but not less than all) of the Securities subject
to such Notice on the same terms and conditions as set forth therein.
Purchaser's purchase right shall be exercised by written notice signed by an
officer of Purchaser (the "Purchaser Notice") and delivered to Parent within
such five (5) day period. Purchaser shall effect the purchase of Purchaser
Common Stock, including payment of the purchase price, not more than three (3)
business days after delivery of Purchaser's Notice, and at such time Parent
shall deliver to Purchaser the certificate(s) representing the Purchaser Common
Stock to be purchased by Purchaser, each certificate to be properly endorsed for
transfer.

                                       B-7



     3.7  Termination. The provisions of this Article 3 shall terminate (other
than insofar they relate to general application of securities laws) upon the
earliest to occur of: (i) the second anniversary date of this Agreement, (ii)
such time as Parent (together with all Controlled Affiliates of Parent)
beneficially owns in the aggregate Voting Securities of Purchaser representing
less than ten (10%) percent of the Total Voting Power of Purchaser or (iii) the
closing or other completion of a Change in Control of Purchaser.

                                   ARTICLE 4

                               REGISTRATION RIGHTS

     4.1  Shelf Registration.

          (a) No later than May 30, 2003, Purchaser shall use its commercially
reasonable efforts to register pursuant to Rule 415(a)(1)(i) under the
Securities Act (or any successor rule with similar effect) a continuous or
delayed offering of Registrable Securities (the "Shelf Registrable Securities")
to be registered so as to permit the sale thereof on and after December 1, 2003
and, in connection therewith, shall prepare and file with the SEC a shelf
registration statement on Form S-3 relating to the Shelf Registrable Securities,
if such Form S-3 is available for use by Purchaser (or any successor form of
registration statement to such Form S-3), to effect such registration (the
"Shelf Registration Statement"), to enable the distribution of the Shelf
Registrable Securities. In connection with the Shelf Registration Statement,
Parent shall undertake to offer or cause the offering of such Shelf Registrable
Securities in accordance with the plan of distribution described in the Shelf
Registration Statement which shall include, to the extent allowable on such
form, exchange transactions or the over-the-counter market transactions; private
transactions other than exchange or over-the-counter market transactions; pledge
to secure debts and other obligations; writing of non-traded and exchange-traded
call options, hedge transactions and in settlement of other transactions in
standardized or over-the-counter options, or a combination of the above
transactions; and provide all such information and materials and take all such
actions as may be required in order to permit Purchaser to comply with all
applicable requirements of the Securities Act, the Exchange Act and the rules
and Regulations of the SEC thereunder, and to obtain any desired acceleration of
the effective date of the Shelf Registration Statement.

          (b) The procedures to be followed by Purchaser and Parent, and the
respective rights and obligations of Purchaser and Parent, with respect to the
preparation, filing and effectiveness of the Shelf Registration Statement and
the distribution of Registrable Securities pursuant to the Shelf Registration
Statement under this Section 4.1 are set forth in Section 4.3 and 4.7 hereof.

     4.2  Piggyback Registration.

          (a) If at any time after the date of this Agreement, Purchaser shall
determine to register any of its equity or equity-linked Securities, including
registration of shares in a so-called unallocated or universal shelf
registration, whether for sale for its own account or for the account of any
other Person, other than registration statements relating to (i) employee,
consultant or distributor compensation or incentive arrangements, including
employee benefit plans, or (ii) acquisitions or any transaction or transactions
under Rule 145 under the Securities Act or any successor rule with

                                       B-8



similar effect, then Purchaser will promptly give Parent written notice thereof
and include in such registration statement (a "Piggyback Registration
Statement") and in any underwriting involved therein, all Registrable Securities
(the "Piggyback Registrable Securities") specified in a written request made by
Parent (a "Piggyback Request") within five (5) business days (or such later time
as the underwriters may allow in writing) after receipt of such written notice
from Purchaser.

          (b) If the Piggyback Registration Statement of which Purchaser gives
notice is for an underwritten offering or Purchaser proposes to do an
underwritten take down from an unallocated or universal shelf registration,
Purchaser shall so advise Parent as a part of the written notice given pursuant
to Section 4.2(a). In such event, the right of Parent to registration pursuant
to this Section 4.2 (or participate in an underwritten take down in the case of
an unallocated or universal shelf registration) shall be conditioned upon the
agreement of Parent to participate in such underwriting and in the inclusion of
such Piggyback Registrable Securities in the underwriting to the extent provided
herein. Parent shall (together with Purchaser and any other holders distributing
Securities in such Piggyback Registration Statement, if any) enter into an
underwriting agreement (the "Piggyback Underwriting Agreement") in customary
form with the underwriter or underwriters selected for such underwriting by
Purchaser. If Parent disapproves of the terms of any such underwriting, it may
elect to withdraw therefrom by written notice to Purchaser and the managing
underwriters. Any Piggyback Registrable Securities excluded or excluded from
such underwriting shall be excluded from such Piggyback Registration Statement.

          (c) Notwithstanding any other provision of this Agreement, if the
managing underwriters of any underwritten offering pursuant to a Piggyback
Request determine, in their sole discretion that, after including all the shares
proposed to be offered by Purchaser and all the shares of any other Persons
entitled to registration rights with respect to such Piggyback Registration
Statement (pursuant to other agreements with Purchaser), marketing factors
require a limitation of the number of Piggyback Registrable Securities to be
underwritten, Purchaser may exclude Piggyback Registrable Securities (a
"Piggyback Market Cut-Back"); provided that if Parent is excluded from
participation in an offering pursuant to a PiggyBack Registration Statement,
such exclusion shall be proportionate to that of such other Persons entitled to
registration rights pursuant to other agreements with Purchaser.

          (d) Except to the extent specifically provided in this Section 4.2,
the procedures to be followed by Purchaser and Parent, and the respective rights
and obligations of Purchaser and Parent, with respect to the distribution of any
Piggyback Registrable Securities by Parent pursuant to any Piggyback
Registration Statement filed by Purchaser shall be as set forth in the Piggyback
Underwriting Agreement, or any other agreement or agreements governing the
distribution of such Piggyback Registrable Securities pursuant to such Piggyback
Registration Statement.

          (e) Notwithstanding the foregoing, however, nothing in this Section
4.2, or any other provision of this Agreement, shall be construed to limit the
absolute right of Purchaser, for any reason and in its sole discretion: (i) to
delay, suspend or terminate the filing of any Piggyback Registration Statement;
(ii) to delay the effectiveness of any Piggyback Registration Statement; (iii)
reduce the number of securities to be distributed pursuant to any Piggyback
Registration Statement; or (iv) to withdraw such Piggyback Registration
Statement.

                                       B-9



     4.3  Shelf Registration Procedures, Rights and Obligations. The procedures
to be followed by Purchaser and Parent, and the respective rights and
obligations of Purchaser and Parent, with respect to the preparation, filing and
effectiveness of the Shelf Registration Statement, and the distribution of
Registrable Securities, pursuant thereto, are as follows:

          (a) Purchaser shall use commercially reasonable efforts to cause the
Shelf Registration Statement to be declared effective prior to December 1, 2003
and to keep the Shelf Registration Statement continuously effective until the
earlier to occur of: (i) the sale or other disposition of all of the Registrable
Securities so registered; (ii) December 1, 2006; and (iii) the termination of
Parent's registration rights pursuant to Section 4.7 hereof. Purchaser shall
prepare and file with the SEC such amendments and supplements to the Shelf
Registration Statement and each prospectus used in connection therewith as may
be necessary to make and to keep the Shelf Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all Registrable Securities proposed to be distributed
pursuant to the Shelf Registration Statement until the earlier to occur of: (i)
the sale or other disposition of all of the Registrable Securities so
registered; (ii) December 1, 2006; and (iii) the termination of Parent's
registration rights pursuant to Section 4.8 hereof.

          (b) Notwithstanding any other provision of this Agreement, in the
event that Purchaser determines that: (i) non-public material information
regarding Purchaser exists, the immediate disclosure of which would be
significantly disadvantageous to Purchaser; (ii) the prospectus constituting the
Shelf Registration Statement covering the distribution of any Registrable
Securities contains an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; or (iii) an offering of Registrable Securities would materially
interfere with any proposed material acquisition, disposition or other similar
corporate transaction or event involving Purchaser (each of the events or
conditions referred to in clauses (i), (ii) and (iii) of this sentence is
hereinafter referred to as a "Suspension Condition"), then Purchaser shall have
the right to suspend any distribution of Registrable Securities pursuant to the
Shelf Registration Statement for so long as such Suspension Condition exists;
provided that Purchaser shall have suspended the filing or effectiveness of all
other registration statements registering securities for the account of
Purchaser or any other Person (including registration statements on Form S-8) or
suspended the distribution of any securities under such registration statements
and; provided further, that in the case of (ii) above, Purchaser shall be
obligated to use best efforts to amend such registration statement to correct
such material misstatement or omission in the Registration Statement and related
prospectus. Purchaser will as promptly as practicable provide written notice to
Parent when a Suspension Condition arises and when it ceases to exist. Upon
receipt of notice from Purchaser of the existence of any Suspension Condition,
Parent shall forthwith discontinue efforts to: (i) file or cause the Shelf
Registration Statement to be declared effective by the SEC (in the event that
the Shelf Registration Statement has not been filed, or has been filed but not
declared effective, at the time Parent receives notice that a Suspension
Condition has arisen); or (ii) offer or sell Registrable Securities (in the
event that the Shelf Registration Statement has been declared effective at the
time Parent receives notice that a Suspension Condition has arisen). In the
event that Parent had previously commenced or was about to commence the
distribution of Registrable Securities pursuant to a prospectus under the Shelf
Registration Statement, then Purchaser shall, as promptly as practicable after
the Suspension Condition ceases to exist, make available to Parent (and to each
underwriter, if any, participating in such distribution) an amendment or
supplement to such

                                      B-10



prospectus. If so directed by Purchaser, Parent shall deliver to Purchaser all
copies, other than permanent file copies then in Parent's possession, of the
most recent prospectus covering Registrable Securities at the time of receipt of
such notice.

          (c) Notwithstanding any other provision of this Agreement, Purchaser
shall not be permitted to postpone (i) the filing or effectiveness of the Shelf
Registration Statement or (ii) the distribution of Registrable Securities
pursuant to the Shelf Registration Statement more than two (2) times in any 360
day period provided that the aggregate of such suspensions may not exceed a
total of ninety (90) days in any 360 day period.

     4.4  Expenses. Parent and Purchaser shall pay their respective Selling
Expenses. Purchaser shall pay all Registration Expenses incurred in connection
with any registration statement that is initiated pursuant to Section 4.2 or 4.3
of this Agreement.

     4.5  Indemnification.

          (a) In the case of any offering registered pursuant to this Article 4,
Purchaser hereby indemnifies and agrees to hold harmless Parent (and its
officers and directors), and each Person, if any, who controls Parent against
any losses, claims, damages or liabilities, joint or several, to which any such
Persons may be subject, under the Securities Act or otherwise, and to reimburse
any of such Persons for any legal or other expenses reasonably incurred by them
in connection with investigating any claims or defending against any actions,
insofar as such losses, claims, damages or liabilities arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the registration statement under which such Registrable Securities
were registered under the Securities Act pursuant to this Article 4, the
prospectus contained therein (during the period that Purchaser is required to
keep such prospectus current), or any amendment or supplement thereto, or the
omission or alleged omission to state therein (if so used) a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances in which they were made, not misleading, except
insofar as such losses, claims, damages or liabilities arise out of or are (i)
based upon any such untrue statement or omission or alleged untrue statement or
omission made in reliance upon information furnished to Purchaser in writing by
Parent or any underwriter for Parent specifically for use therein, or (ii) made
in any preliminary prospectus, and the prospectus contained in the registration
statement as declared effective or in the form filed by Purchaser with the SEC
pursuant to Rule 424 under the Securities Act shall have corrected such
statement or omission and a copy of such prospectus shall not have been sent or
otherwise delivered to such Person at or prior to the confirmation of such sale
to such Person.

          (b) By requesting registration under this Article 4, Parent agrees, if
Registrable Securities held by Parent are included in the Securities as to which
such registration is being effected, to indemnify and to hold harmless Purchaser
and its directors and officers and each Person, if any, who controls Purchaser
within the meaning of the Securities Act against any losses, claims, damages or
liabilities, joint or several, to which any of such Persons may be subject under
the Securities Act or otherwise, and to reimburse any of such Persons for any
legal or other expenses incurred in connection with investigating or defending
against any such losses, claims, damages or liabilities, but only to the extent
it arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission of a material fact in any registration
statement

                                      B-11



under which the Registrable Securities were registered under the Securities Act
pursuant to this Article 4, any prospectus contained therein, or any amendment
or supplement thereto, which was based upon and made in conformity with
information about Parent furnished to Purchaser in writing by Parent or such
underwriter expressly for use therein.

               (c) Each party entitled to indemnification under this Section 4.4
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at its own
expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Article 4 unless such failure resulted in actual
detriment to the Indemnifying Party. No Indemnifying Party, (i) in the defense
of any such claim or litigation, shall, except with the consent of each
Indemnified Party, which consent shall not be unreasonably withheld, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation, or (ii) shall be liable for amounts paid in any settlement if such
settlement is effected without the consent of the Indemnifying Party, which
consent shall not be unreasonably withheld.

         4.6   Information by Parent. Parent shall furnish to Purchaser such
information regarding Parent and the distribution of Registrable Securities
proposed by Parent as Purchaser may reasonably request in writing and as shall
be required in connection with any registration, qualification or compliance
referred to in this Article 4.

         4.7   Obligations of Purchaser. Whenever required under Section 4.1 or
4.2 to effect the registration of any Registrable Securities, Purchaser shall:

               (a) Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement.

               (b) Furnish to Parent such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

               (c) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or "blue sky"
laws of such states or jurisdictions as shall be reasonably requested by Parent,
provided, however, that Purchaser shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

                                      B-12



               (d) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form (including indemnity provisions), with the managing underwriter
of such offering.

               (e) Notify Parent, at any time when a prospectus covered by such
registration statement is required to be delivered under the Securities Act, of
the happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, either (a) includes an untrue
statement or a material fact or omits to a state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing or (b) to Purchaser's knowledge, fails
to comply with the Securities Act or any other applicable federal or state
securities laws.

               (f) Furnish, at the request of Parent, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to Article 4, if such securities are being sold
through underwriters, on the date that the registration statement with respect
to such securities become effective, (a) an opinion, dated such date, of the
counsel representing Purchaser for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Parent and (b)
certificates confirming representations and warranties by Purchaser, in form and
substance as is customarily given to underwriters in an underwritten public
offering delivered to and for the benefit of the underwriters, if any, and
Parent and (c) a letter dated such date, from the independent certified public
accountants of Purchaser, in form and substance as is customarily given by

                          SUBORDINATED PROMISSORY NOTE

               "This Note has not been registered or qualified under
               the Securities Act of 1933, as amended, or under any
               state securities or "blue sky" laws, and may not be
               transferred or disposed of by the holder in the absence

               upon an exemption therefrom."

$____________                                                   Portland, Oregon

                                                              November ___, 2002

FOR VALUE RECEIVED, Tut Systems, Inc. ("Debtor"), promises to pay to the order
of Tektronix, Inc. ("Holder"), the principal sum of [the Initial Note Face
Value] ($__________), as such sum may be adjusted pursuant to Section 4 hereof
from time to time, and to pay interest on the outstanding principal and accrued
interest of this Subordinated Promissory Note (this "Note") in accordance with
Sections 2 and 3 of this Note. Payment of principal and interest on this Note
shall be made by wire transfer or delivery of other immediately available funds
in accordance with reasonable instructions by Holder from time to time and shall
be payable in United States dollars. The interest on any payments not paid when
due, after an extended period for payment of five (5) days, shall bear interest
for such period as such payments have not been made, at a rate that is 5% per
annum in excess of the interest rate otherwise payable under this Note. This
Note is delivered in connection with that certain Agreement and Plan of Merger
by and among Debtor, Tiger Acquisition Corporation, VideoTele.com, Inc. and
Holder dated as of October 28, 2002 (the "Agreement").

     1. MATURITY. Debtor shall repay the unpaid principal outstanding balance
plus all unpaid interest accrued thereon by means of a single, lump sum payment
on ____________ (the "Repayment Date"). All payments received shall be applied
first against costs of collection (if any), then against accrued and unpaid
interest, then against principal.

     2. DEFINITIONS. All terms not defined herein shall have the meanings
assigned to them in the Agreement (including the Exhibits thereto). For the
purposes hereof, "Downward Adjustment Items" means (i) the Stock Price
Adjustment (if negative), (ii) any PNV Adjustment (if negative) pursuant to
Section 1.15 of the Agreement, and (iii) the indemnification obligations of
Holder under Articles VIII and IX of the Agreement.

     3. TERM OF NOTE; INTEREST; REPAYMENT. The term of this Note will begin on
the Effective Date and end on the Repayment Date. Interest on the unpaid
principal balance (such unpaid principal balance is referred to as the
"Outstanding Balance") will accrue from the Effective Date at the rate of eight
percent (8%) per annum, calculated on an annual compound basis for a 360 day
year and actual days elapsed; provided, however, that no such accrued interest
shall be due and payable prior to January 31, 2006, and any interest accrued
prior to such date and shall be added to



the principal balance of the Note. The Debtor will pay accrued interest on the
Note commencing on January 31, 2006 and on each April 30, July 31 and October 31
thereafter until the principal balance has been paid in full.

     4. AUTOMATIC ADJUSTMENT OF PRINCIPAL AMOUNT OF NOTE.

        (a) Adjustment.

             (i)  The principal balance of the Note shall be automatically
increased for any upward Stock Price Adjustment or a positive PNV Adjustment.

             (ii) The principal balance of the Note shall be automatically
reduced upon a determination pursuant to the Agreement that a Downward
Adjustment Item exists.

        (b) Notification of Adjustment. Upon any adjustment set forth in this
Section 4, Debtor shall send written notice to Holder of the amount of the
adjustment and the reason therefore within ten (10) business days after such
reduction. Upon request of the Holder, Debtor shall execute and deliver to
Holder a replacement note setting forth the revised principal amount.

     5. SUBORDINATION. The indebtedness evidenced by this Note is hereby
expressly subordinated in right of payment to all obligations at any time owing
by the Debtor to any (i) bank, financial or lending institution or other
non-affiliated entity primarily in the business of extending credit or other
financial accommodations in connection with borrowed money for working capital
or capital improvements or for capitalized leases ("Permitted Obligations"); and
(ii) reimbursement or subrogation obligations to any entity which has guaranteed
any such obligation of the Debtor (collectively, "Senior Indebtedness"). Debtor
may not make any payment upon or in respect of this Note (including upon
redemption) if (i) a default in the payment of, premium, if any, interest, rent
or other obligations in respect of Senior Indebtedness occurs and is continuing
beyond any applicable period of grace (a "Payment Default") or (ii) any other
default occurs and is continuing with respect to Senior Indebtedness that
permits holders of such Senior Indebtedness as to which the default relates to
accelerate its maturity and Parent receives a notice of such default (a "Payment
Blockage Notice") from Purchaser (a "Non-Payment Default"). Payments on the Note
may and shall be resumed (a) in case of a Payment Default, upon the date on
which such default is cured or waived or ceases to exist and (b) in the case of
a Non-Payment Default, the earlier of the date on which such nonpayment default
is cured or waived or ceases to exist or 270 days after the date on which the
applicable Payment Blockage Notice is received. Until such times as set forth in
(a) and (b) above, Holder shall not ask, demand or sue for any amounts owing
hereunder, accept any payment or transfer of property in settlement thereof, or
take any action inconsistent with the rights of the holders of the Senior
Indebtedness, including the initiation of any insolvency proceeding against
Debtor; provided, however, that the foregoing shall not apply after the payment
in full of Senior Indebtedness. Notwithstanding the foregoing, nothing in this
Section 4 shall affect Holder's right to accelerate this Note pursuant to
Section 7.

     6. PREPAYMENT TERMS. All or any portion of the principal amount of the Note
may be prepaid by Debtor without penalty at any time following the Effective
Date, upon one day's prior notice to Holder.

                                       C-2



     7. ACCELERATION. The principal balance of the Note may be accelerated on
the following basis:

        7.1 Acceleration on Change of Control. Upon the occurrence of any of the
following, Holder may, at its option and in its sole discretion, require the
immediate payment of all or a portion of the principal balance of the Note:

        (a) the closing of any agreement between Debtor and any person or group
(other than Holder) that results in a Change of Control; or

        (b) the closing by any person, entity or group of a tender offer or
exchange offer that results in a Change of Control (a "Third Party Offer").

     For purposes of this Note, a "Change of Control" shall be deemed to have
occurred with respect to Debtor if:

            (i)   any "person," "entity" or "group" within the meaning of
Sections 13(d) and 14(d) of the Exchange Act of 1934, as amended (the "Exchange
Act"), (other than Debtor, a Controlled Affiliate of Debtor, any trustee or
other fiduciary holding securities under any compensatory benefit plan of Debtor
or an Affiliate of Debtor, or any entity owned directly or indirectly by the
stockholders of Debtor in substantially the same proportions as their ownership
of stock of Debtor), is or becomes the "beneficial owner" (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of voting securities
representing more than fifty percent (50%) of Debtor's then outstanding voting
securities;

            (ii)  a merger or consolidation of Debtor with any other corporation
which is not a Controlled Affiliate of the Debtor is consummated, other than a
merger that would result in the voting securities of the company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving
entity) more than fifty percent (50%) of the combined voting power of the voting
securities of Debtor (or the comparable voting securities of such surviving
entity) outstanding immediately after such merger or consolidation, provided,
that a merger or consolidation effected to implement a recapitalization of
Debtor or an Affiliate thereof (or similar transaction) in which no person
acquires more than thirty percent (30%) of the combined voting power of Debtor's
then outstanding voting securities shall not constitute a "Change of Control" of
Debtor; or

            (iii) the sale or disposition by Debtor of all or a majority of
Debtor's assets, other than to a Controlled Affiliate of Debtor, is consummated.

     For purposes of this Note,

        (c) "Affiliate" shall mean, with respect to any specified person, a
person that directly or indirectly, through one or more intermediaries,
controls, is controlled by, or is under common control with, the person
specified; and

        (d) "Controlled Affiliate" with respect to a person shall mean any
Affiliate of such person that is controlled by such person.

                                       C-3



     8. Default. For purposes of this Note, the term "default" shall include any
of the following:

        (a) The failure by Debtor to pay any amounts due hereunder when due;

        (b) Debtor's indebtedness for borrowed money in excess of $2,500,000 is
accelerated as a result of a default or breach of or under any agreement for
such borrowed money, including but not limited to loan agreements;

        (c) The filing of a petition in bankruptcy or under any similar
insolvency law by Debtor, the making of an assignment for the benefit of
creditors, or if any involuntary petition in bankruptcy or under any similar
insolvency law is filed against Debtor and such petition is not dismissed within
forty-five (45) days after the filing thereof.

     Debtor shall have thirty (30) days to cure any default pursuant to Section
8(b), after receipt of written notice of default from Holder specifying the
nature of Debtor's default. If the default is pursuant to Section 8(a) or 8(c)
or if Debtor is unable to cure its pursuant to Section 8(b) within such thirty
(30) day period, Holder may, at its option, accelerate repayment of the
principal amount hereof in which case it shall be due and payable immediately.
If the default is pursuant to Section 8(c), acceleration shall occur immediately
without the action of Holder. Upon any default of Debtor hereunder, Holder may
pursue any legal or equitable remedies that has available to it.

     9. Miscellaneous.

        (a) Debtor hereby waives presentment, demand, protest, notice of
dishonor, diligence and all other notices, any release or discharge arising from
any extension of time, discharge of a prior party, release of any or all of any
security given from time to time for this Note, or other cause of release or
discharge other than actual payment in full hereof.

        (b) Holder shall not be deemed, by any act or omission, to have waived
any of its rights or remedies hereunder unless such waiver is in writing and
signed by Holder and then only to the extent specifically set forth in such
writing. A waiver with reference to one event shall not be construed as
continuing or as a bar to or waiver of any right or remedy as to a subsequent
event. No delay or omission of Holder to exercise any right, whether before or
after a default hereunder, shall impair any such right or shall be construed to
be a waiver of any right or default, and the acceptance at any time by Holder of
any past due amount shall not be deemed to be a waiver of the right to require
prompt payment when due of any other amounts then or thereafter due and payable.

        (c) The remedies of Holder as provided herein, or any one or more of
them, or in law or in equity, shall be cumulative and concurrent, and may be
pursued singularly, successively or together at Holder's sole discretion, and
may be exercised as often as occasion therefor shall occur.

        (d) It is expressly agreed that if this Note is referred to an attorney
or if suit is brought to collect or interpret this Note or any part hereof or to
enforce or protect any rights conferred upon Holder by this Note or any other
document evidencing or securing this Note, then Debtor promises and agrees to
pay the reasonable costs, including, without limitation, any such costs at trial
and on appeal.

                                       C-4



        (e) If any provisions of this Note would require Debtor to pay interest
hereon at a rate exceeding the highest rate allowed by applicable law, Debtor
shall instead pay interest under this Note at the highest rate permitted by
applicable law.

        (f) This Note shall be governed by and construed in accordance with and
the laws of the State of Oregon applicable to contracts wholly made and
performed in the State of Oregon.

        (g) Holder may not transfer or assign any interest on this Note or any
of its rights hereunder.

                                       C-5



     IN WITNESS WHEREOF, Debtor has executed this Subordinated Promissory Note

               6.1  Entire Agreement/Modification. This Agreement, together with
the Asset Transfer Agreement, contains the entire agreement between the parties
with respect to the subject matter hereof, and unless otherwise provided in this
Agreement, no modification or waiver of any of the provisions, or any future
representation, promise, or addition, shall be binding upon the parties unless
made in writing and signed by both parties. For avoidance of doubt, this
Agreement is intended to supplement the Technology Transfer Agreement. To the
extent any grant of rights described herein was already made as of the Effective
Date under the Technology Transfer Agreement, this Agreement will not be
construed to vitiate such grant. To the extent of any conflict between the scope
of rights to particular Technology granted in this Agreement and the Technology
Transfer Agreement, the agreement granting the broader rights will govern.

               6.2  Waiver. The failure of either party to enforce at any time
any provision hereof shall not be construed to be a waiver of such provision or
of the right thereafter to enforce each and every provision. No waiver by either
party to this Agreement, either express or implied, of any breach of any term,
condition, or obligation of this Agreement, shall be construed as a waiver of
any subsequent breach of that term, condition, or obligation or of any other
term, condition or obligation of this Agreement.

               6.3  Force Majeure. Neither party shall be held responsible
because of any delay in performance or noncompliance with any provision of this
Agreement that results from an act, event, omission, or cause beyond its
reasonable control and without its fault or negligence, including but not
limited to, strikes, walkouts, civil commotion, riots, wars, fires, explosions,
floods, earthquakes, embargoes, or acts of civil or military authority.

               6.4  Independent Contractors. The parties to this Agreement are
independent contractors. Nothing contained in this Agreement shall be construed
to create relationships of partnership, joint venture, or employment between the
parties.

               6.5  Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their permitted successors
and assigns. Neither party may assign its rights under this Agreement, in whole
or in part, without the written consent of the other party, provided, however,
that VTC may assign or sublicense all of its rights under this Agreement to a
VTC Affiliate, including in connection with a merger, acquisition, or sale of
all or substantially all of its assets related to the VTC Field of Use, and
Tektronix may assign or sublicense all of its rights under this Agreement to a
Tektronix Affiliate, including in connection with a merger, acquisition, or sale
of all or substantially all of its assets related to the Tektronix Field of Use.
For avoidance of doubt, in the event either party assigns this Agreement as
allowed under this Section 6.5, the assigning part will continue to be obligated
not to assert its patent rights as described in Section 2.4 or 2.5, as
applicable.

               6.6  Severability. If any provision, term, condition, covenant,
restriction, or other portion of this Agreement shall be held to be invalid,
illegal, or unenforceable by any court of competent jurisdiction, the remaining
portion shall remain in force and effect.

               6.7  Attorneys' Fees. If litigation or arbitration is commenced
by either party to enforce or interpret any of the provision of this Agreement,
the prevailing party shall be entitled to recover reasonable costs, expenses and
attorneys' fees at arbitration, trial, on appeal, and on any petition for
review.

               6.8  Headings. Headings used herein are for convenience only and
shall not be construed a part of, or affect the construction or interpretation
of, any provision of this Agreement.

               6.9  Disputes/Governing Law. This Agreement shall be deemed to
have been executed in, and shall be exclusively governed by and interpreted in
accordance with the laws of, the State of Oregon, excluding choice of law rules.

               6.10 Notices. Any notice or report hereunder shall be given in
writing. Notices that affect the other party's rights under this Agreement shall

immediately prior to the Closing Date, including associated utilities;

               (b)  Services related to acting as the consignee for importation
of Tut Systems demonstration products, provided that Tut Systems adheres to
Tektronix's importation policies and further provided that Tut Systems complies
with the Chinese temporary import laws. Any cost associated with non-compliance
of such laws shall be the responsibility of Tut Systems;

               (c)  Services related to the payment of approved VTC business
expenses; and

               (d)  Payroll and employee services, as follows:

                       (1) The persons identified on Schedule 1.1 (the
"Employees") shall perform services exclusively for Tut Systems.

                       (2) Until such time as Tut Systems has established an
entity that can operate in China and employ the Employees, but not later than
termination of this agreement, Tektronix shall administer on Tut Systems' behalf
the payroll and benefit functions of Tut Systems with respect to the Employees.

                       (3) Employees shall report to and be directed by Tut
Systems, and only Tut Systems may terminate their employment.

                       (4) Prior to termination of this agreement, Tut Systems
may hire one (1) additional employee that would be subject to this Agreement.

                       (5) Applicable costs associated with this Service include
payroll, benefits, and any severance or other costs associated with the
Employees' termination.

     2.   COOPERATION AND ACCESS.

order to effectuate the Services. Such cooperation includes, but is not limited
to, providing the Employees with reasonable access to its facilities, as needed,
in order to enable the Employees to perform the Services as well as cooperating
with any request by Tut Systems for additional services, provided such services
are consistent with past practice.

     3.   FEES AND REIMBURSEMENT.

     Tut Systems shall reimburse Tektronix for all costs associated with the
Services provided pursuant to this Agreement on a monthly basis consistent with
past practices for determining and allocating such costs within fifteen (15)

THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
NON-INFRINGEMENT WITH RESPECT THERETO.

     5.   TERM AND TERMINATION.

          5.1  The term of this Agreement shall begin on the Closing Date and

earlier terminated as provided herein. Tut Systems will, beginning on the
Closing Date, diligently pursue the establishment of all necessary entities,
licenses, real property leases, permits, payroll systems and third party service
providers necessary to maintain the China Office without assistance from
Tektronix. Tut Systems shall, at reasonable intervals (but not less often than
monthly), report to Tektronix the status of such efforts. Each of the Services
herein shall terminate earlier upon Tut Systems' establishing independent
systems or relationships for providing the services.

          5.2  Tut Systems may terminate all or any Service(s) provided pursuant
to this Agreement on ten (10) days prior written notice to Tektronix. Upon the
termination of all Services or the Service described in Section 1(d) hereto,
Employees shall become the employees of Tut Systems. In the event the services
of Employees are not required by Tut Systems upon such termination, Employees
shall be terminated from employment and Tut Systems shall be responsible for all
costs of termination.

               (a)  In the event of a material breach under this Agreement, the
non-defaulting Party may terminate the specific Service(s) to which such breach
relates if the defaulting Party fails to cure such breach within thirty (30)
days (twenty (20) days after written notice of payment default) of its receipt
of a written notice from the non-defaulting Party of such breach, provided that
the duties and obligations of the defaulting Party which have accrued prior to
the termination of such Service shall not be released or discharged by such
termination.

               (b)  In the event Tut Systems fails to pay an amount invoiced
pursuant to Section 3 of this Agreement due to a dispute between the Parties
regarding the amount invoiced for the Service(s), such nonpayment will not be
deemed a material breach under this Agreement and the Parties shall have twenty
(20) days in which to resolve the dispute provided Tut Systems pays an amount it
reasonably believes to be correct pursuant to this Agreement during this twenty
(20) day period.

               (c)  Tektronix shall execute any further assignments or other
documents as shall reasonably be requested by Tut Systems to effect the
foregoing.

          5.3  Upon termination of any Service(s) provided hereunder, Tektronix
shall transfer to Tut Systems a copy of all reasonably available data related to
such Service(s).
