 ---------
corporation ("Onvia"), Zanova Acquisition Corporation, a Delaware corporation
              -----

deemed it advisable and in the best interests of each corporation and its

Internal Revenue Code of 1986, as amended (the "Code");
                                                ----

         D.     For accounting purposes, it is intended that the Merger shall be
accounted for as a purchase transaction; and

         E.     As a condition and inducement to Onvia's willingness to enter
into this Agreement, certain Zanova stockholders holding no less than eighty
eight percent (88%) of the issued and outstanding capital stock of Zanova have,
concurrently with the execution of this Agreement, executed and delivered Voting
Agreements in the form attached hereto as Exhibit A (the "Voting Agreements"),
                                          ---------       -----------------
pursuant to which such stockholders have, among other things, agreed to vote
their shares of Zanova capital stock in favor of the Merger and to grant Onvia
irrevocable proxies to vote such shares; and

         F.     This Agreement has been adopted and approved by the respective
boards of directors of Onvia, Sub and Zanova.

         NOW, THEREFORE, in consideration of the foregoing recitals and the
respective representations, warranties, covenants and agreements set forth

                  (a)  From and after the Effective Time, each holder of an
outstanding certificate or certificates ("Certificates") which represented

                  (b)  If any shares of Onvia Common Stock are to be issued in
the name of a person other than the person in whose name the Certificate(s)
surrendered in exchange therefor is registered, it shall be a condition to the
issuance of such shares that (i) the Certificate(s) so surrendered shall be
transferable, and shall be properly assigned, endorsed or accompanied by
appropriate stock powers, (ii) such transfer shall otherwise be proper and (iii)
the person requesting such transfer shall pay Onvia, or its exchange agent, any
transfer or other taxes payable by reason of the foregoing or establish to the

a holder of shares of Zanova Capital Stock for shares of Onvia Common Stock
issuable to such holder pursuant to the provisions of Article II of this
Agreement that are delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

                  (c)  In the event any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed, Onvia shall issue in
exchange for such lost, stolen or destroyed Certificate the shares of Onvia
Common Stock issuable in exchange therefor pursuant to the provisions of Article
II of the Agreement. The board of directors of Onvia, or Onvia's exchange agent
(if any), may in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificate to

made against Onvia with respect to the Certificate alleged to have been lost,
stolen or destroyed.

                  (d)  Onvia agrees to make available to its exchange agent, if

dividends or other distributions declared or made after the Effective Time with
respect to Onvia Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Onvia Common Stock represented thereby below until the holder of

time of such surrender, the amount of any dividends or other distributions with
a record date after the Effective Time previously paid with respect to such

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

               (a)     Zanova has delivered to Onvia copies of Zanova's
unaudited balance sheet as of March 31, 2000 (the "Most Recent Balance Sheet")
                                                   -------------------------
and statements of operations for the three-month period then-ended (together
with the Most Recent Balance Sheet, the "Zanova Interim Financials") and
                                         -------------------------
Zanova's audited balance sheets as of December 31, 1999 and 1998, and the
related audited statements of operations, stockholders' equity and cash flows
for the years ended December 31, 1999 and 1998, respectively (together with the
Zanova Interim Financials, the "Zanova Financial Statements").
                                ---------------------------

               (b)     Other than as set forth on the Zanova Disclosure
Schedule, the Zanova Financial Statements are in accordance with the books and
records of Zanova and present fairly in all material respects the financial
position, results of operations and cash flows of Zanova as of their historical
dates and for the periods indicated. The Zanova Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a basis consistent with prior periods. The reserves, if any, reflected on the

respect to which they were made.

               (c)     Except as set forth in Schedule 3.4(c) of the Zanova

accordance with generally accepted accounting principles applied on a basis
consistent with prior periods, to be included in a balance sheet or the notes
thereto. All material debts, liabilities, and obligations incurred after the
date of the Most Recent Balance Sheet were incurred in the ordinary course of
business and are not material either individually or in the aggregate to Zanova
or its business.

         Section 3.5   Tax Matters.
                       -----------

               (a)     For purposes of this Section 3.5 and other provisions of
this Agreement relating to Taxes, the following definitions shall apply:

                       (i)  The term "Taxes" shall mean all taxes, however
                                      -----
denominated, including any interest, penalties or other additions to tax that
may become payable in respect thereof, (A) imposed by any federal, territorial,
state, local or foreign government or any agency or political subdivision of any
such government, which taxes shall include, without limiting the generality of
the foregoing, all income or profits taxes (including but not limited to,
federal income taxes and state income taxes), payroll and employee withholding
taxes, unemployment insurance, social security taxes, sales and use taxes, ad
valorem taxes, excise taxes, franchise taxes, gross receipts taxes, business
license taxes, occupation taxes, real and personal property taxes, stamp taxes,
environmental taxes, ozone depleting chemicals taxes, transfer taxes, workers'
compensation, Pension Benefit Guaranty Corporation premiums and other
governmental charges, and other obligations of the same or of a similar nature
to any of the foregoing, which are required to be paid, withheld or collected,
(B) any liability for the payment of amounts referred to in (A) as a result of
being a member of any affiliated, consolidated, combined or unitary group, or
(C) any liability for amounts referred to in (A) or (B) as a result of any
obligations to indemnify another person.

                       (ii) The term "Returns" shall mean all reports,
                                      -------
estimates, declarations of estimated tax, information statements and returns
relating to, or required to be filed in connection with, any Taxes, including
information returns or reports with respect to backup withholding and other
payments to third parties.

               (b)     Except as set forth in Schedule 3.5(b) of the Zanova
Disclosure Schedule, all Returns required to be filed prior to the date hereof
by or on behalf of Zanova have been duly filed on a timely basis, and such
Returns are true, complete and correct in all material respects. All Taxes shown
to be payable on such Returns or on subsequent assessments with respect thereto,
and all payments of estimated Taxes required to be made prior to the date hereof
by or on behalf of Zanova under Section 6655 of the Code or comparable
provisions of state, local or foreign law, have been paid in full on a timely
basis or have been accrued on the Most Recent Balance Sheet, and no other Taxes
are payable by Zanova with respect to items or periods covered by such Returns
(whether or not shown on or reportable on such Returns). Zanova has withheld and
paid over all Taxes required to have been withheld and paid over prior to the
date hereof , and complied with all information reporting and backup withholding
requirements, including maintenance of required records with respect thereto, in
connection with amounts paid or owing to any employee, creditor, independent
contractor, or other third party. There are no liens on any of the assets of
Zanova with respect to Taxes, other than liens for Taxes not yet due and payable
or for Taxes that Zanova is contesting in good faith through appropriate
proceedings and for which appropriate reserves have been established on the Most
Recent Balance Sheet. Zanova has not at any time been (i) a member of an
affiliated group of corporations filing

                                     -12-
<PAGE>

consolidated, combined or unitary income or franchise tax returns, or (ii) a
member of any partnership or joint venture for a period for which the statue of
limitations for any Tax potentially applicable as a result of such membership
has not expired.

               (c)     The amount of Zanova's liability for unpaid Taxes
(whether actual or contingent) for all periods through the date of the Most
Recent Balance Sheet does not, in the aggregate, exceed the amount of the
current liability accruals for Taxes reflected on the Most Recent Balance Sheet,
and the Most Recent Balance Sheet reflects proper accrual in accordance with
generally accepted accounting principles applied on a basis consistent with
prior periods of all liabilities for Taxes payable after the date of the Most
Recent Balance Sheet attributable to transactions and events occurring prior to
such date. No liability for Taxes has been incurred (or prior to Closing will be
incurred) since such date other than in the ordinary course of business.

               (d)     Zanova has made available to Onvia true and complete
copies of (i) relevant portions of income tax audit reports, statements of
deficiencies, closing or other agreements received by or on behalf of Zanova
relating to Taxes, and (ii) all federal and state income or franchise tax
Returns and state sales and use tax Returns for or including Zanova for all
periods since the inception of Zanova. Zanova does not do business in or derive
income from any state other than states for which Returns have been duly filed
and furnished to Onvia.

               (e)     The Returns of or including Zanova have never been
audited by a government or taxing authority, nor is any such audit in process,
pending or, to Zanova's knowledge, threatened (either in writing or verbally,
formally or informally). No deficiencies exist or have been asserted (either in
writing or verbally, formally or informally), and Zanova has not received notice
(either in writing or verbally, formally or informally) that it has not filed a
Return or paid Taxes required to be filed or paid. Zanova is neither a party to
any action or proceeding for assessment or collection of Taxes, nor has such
event been asserted or, to the knowledge of Zanova, threatened (either in
writing or orally, formally or informally) against Zanova or any of its assets.
No waiver or extension of any statute of limitations is in effect with respect
to Taxes or Returns of Zanova. Zanova has disclosed on its federal and state
income and franchise tax Returns all positions taken therein that could give
rise to a substantial understatement penalty within the meaning of Code Section
6662 or comparable provisions of applicable state, local, foreign or other tax
laws.

               (f)     Except as may be required as a result of the Merger,
Zanova and its subsidiaries have not been and will not be required to include
any material adjustment in taxable income for any Tax period (or portion
thereof) pursuant to Section 481 or Section 263A of the Code or any comparable
provision under state or foreign Tax laws as a result of transactions, events or
accounting methods employed prior to the Closing.

               (g)     Zanova is not, nor has it ever been, a party to any tax
sharing agreement. Since April 16, 1997, Zanova has not been a distributing
corporation or a controlled corporation in a transaction described in Section
355(a) of the Code.

               (h)     Zanova is not, nor has it been, a United States real
property holding corporation within the meaning of Section 897(c)(2) of the Code
during the applicable period

                                     -13-
<PAGE>

specified in Section 897(c)(1)(A)(ii) of the Code, and Onvia is not required to
withhold tax by reason of Section 1445 of the Code. Zanova is not a "consenting
corporation" under Section 341(f) of the Code. Zanova has not entered into any
compensatory agreements with respect to the performance of services which
payment thereunder would result in a nondeductible expense to Zanova pursuant to
Section 280G of the Code or an excise tax to the recipient of such payment
pursuant to Section 4999 of the Code. Zanova has not agreed to, nor is it
required to make any adjustment under Code Section 481(a) by reason of, a change
in accounting method. Zanova is not, nor has it been, a "reporting corporation"
subject to the information reporting and record maintenance requirements of
Section 6038A and the regulations thereunder. Zanova is in compliance with the
terms and conditions of any applicable tax exemptions, agreements or orders of
any foreign government to which it may be subject or which it may have claimed,
and the transactions contemplated by this Agreement will not have any adverse
effect on such compliance.

               (i)     The Zanova Disclosure Schedule sets forth accurate and
complete information regarding Zanova's net operating losses for federal and
each applicable state income tax purposes. Except as a result of the
transactions contemplated hereby, Zanova has no net operating losses and credit
carryovers or other tax attributes currently subject to limitation under
Sections 382, 383, or 384 of the Code.

                       -------------------------
title to all its properties, interests in properties and assets, real and

www.zanova.com and the other domain names listed in the Zanova Disclosure
Schedule) or any product which has been or is being distributed or sold by
Zanova or currently is under development by Zanova or has previously been under
development by Zanova (collectively, including such Web sites, the "Zanova
                                                                    ------
Products"), free and clear of all liens, claims and encumbrances (including
--------
without limitation licensing and distribution rights) (all of which are referred
to as "Zanova Proprietary Rights"). The Zanova Disclosure Schedule contains an

Zanova Proprietary Right has been issued or registered or in which any such
application of such issuance and registration has been filed, (ii) list of all
licenses and other agreements with third parties (the "Third Party Licenses")
                                                       --------------------
relating to any material patents, copyrights, trade secrets, software,
inventions, technology, know-how, processes or other proprietary rights that
Zanova is licensed or otherwise authorized by such third parties to use, market,
distribute or incorporate in Zanova Products (such patents, copyrights, trade
secrets, software, inventions, technology, know-how, processes or other
proprietary rights are collectively referred to as the "Third Party Technology")

and (iii) list of all licenses and other agreements with third parties relating
to any material information, compilations, data lists or databases that Zanova

registrations, if any, related to or in the Zanova Products are valid and in
full force and effect, and except as set forth on the Zanova Disclosure
Schedule, consummation of the transactions contemplated in this Agreement will
not alter or impair any such rights. Except as set forth on the Zanova
Disclosure Schedule, no claims have been asserted or threatened against Zanova
(and Zanova is not aware of any claims which are likely to be asserted or
threatened against Zanova or which have been asserted or threatened against
others relating to Zanova Proprietary Rights or Zanova Products) by any person

basis for any claim of the type specified in the immediately preceding sentence
which could in any material way relate to or interfere with the continued
exploitation by Zanova of any of the Zanova Products in their current form. None
of the Zanova Products in their current form nor the use or exploitation of any
Zanova Proprietary Rights in Zanova's current business infringes on the rights
of or constitutes misappropriation of any proprietary information or intangible
property right of any third person or entity, including without limitation any
patent, trade secret, copyright, trademark or trade name, and except as set
forth on the Zanova Disclosure Schedule, Zanova has not been sued or named in
any suit, action or proceeding which involves a claim of such infringement,
misappropriation or unfair competition.

               (b)     Except as set forth in Schedule 3.11(a) of the Zanova
Disclosure Schedule, Zanova has not granted any third party any right to

any portion thereof. Except with respect to the rights of third parties to the

distribute, market or exploit any works or materials of which any of the Zanova
Products are a "derivative work" as that term is defined in the United States
Copyright Act, Title 17, U.S.C. Section 101.

               (c)     Except for Third Party Technology subject to the Third
Party Licenses, all material designs, drawings, specifications, source code,
object code, scripts, documentation, flow charts, diagrams, data lists,
databases, compilations and information incorporating, embodying or reflecting
any of the Zanova Products at any stage of their development (the "Zanova
                                                                   ------

----------
employees of Zanova without the assistance of any third party or entity or were
created by third parties who assigned ownership of their rights to Zanova by
means of valid and enforceable confidentiality and invention assignment
agreements, copies of which have been delivered to Onvia. Except as set forth in
Schedule 3.8(c) of the Zanova Disclosure Schedule, Zanova has at all times used
commercially reasonable efforts customary in its industry to treat the Zanova
Proprietary Rights related to Zanova Products and Zanova Components as
containing trade secrets and, other than as provided in Schedule 3.11(a) of the
Zanova Disclosure Schedule, has not disclosed or otherwise dealt with such items
in a manner intended or reasonably likely to cause the loss of such trade
secrets by release into the public domain; provided, that the Zanova has

of the Zanova Disclosure Schedule, source code of its products to its licensees.

consultant of Zanova is in violation in any material respect of any term of any
written employment contract, patent disclosure agreement or any other written
contract or agreement relating to the relationship of any such employee,
consultant or contractor with Zanova or, to Zanova's knowledge, any other party
because of the nature of the business conducted by Zanova or proposed to be
conducted by Zanova. Except for Third Party Technology subject to Third Party
Licenses, the Zanova Disclosure Schedule lists all employees, contractors and
consultants who have participated in any way in the development of any material
portion of the Zanova Products or the Zanova Proprietary Rights.

               (e)     Except as set forth in Section 3.8(e) of the Zanova

(including independent contractors, if any) with access authorized by Zanova to
confidential information of Zanova has executed a confidentiality and non-

Onvia or its representatives.

               (f)     No product liability or warranty claims have been
communicated in writing to or threatened against Zanova.

               (g)     To Zanova's knowledge, there is no material unauthorized

Rights, or any Third Party Technology to the extent licensed by or through
Zanova, by any third party, including any employee or former employee of Zanova.
Except as set forth in Schedule 3.11(a) to the Zanova Disclosure Schedule,
Zanova has not entered into any agreement to indemnify any other person against
any charge of infringement of any Zanova Proprietary Rights.

               (h)     Zanova has taken all steps customary and reasonable in
the industry to protect and preserve the confidentiality and proprietary nature
of all Zanova Proprietary Rights and other confidential information not
otherwise protected by patents, patent applications or copyright ("Confidential

-----------
knowledge, by another party pursuant to rights granted to it by Zanova, of
Confidential Information owned by Zanova to a third party has been pursuant to
the terms of a written agreement between Zanova and such third party. All use,
disclosure or appropriation by Zanova of Confidential Information not owned by
Zanova has been pursuant to the terms of a written agreement between Zanova and
the owner of such Confidential Information, or is otherwise lawful.

               (i)     Notwithstanding anything to the contrary in this Section
3.8, Zanova shall not be responsible or liable in any way, including any
indemnity obligation under Section 10.1, for breaches of the warranties and/or
representations contained herein resulting from: (1) derivative works created by
Onvia or any other third party based on the Zanova Products; (2) use of the

               (b)     Zanova has made available to Onvia or its representatives
a copy of each of the Zanova Employee Plans and related plan documents
(including trust documents, insurance policies or contracts, employee booklets,
summary plan descriptions and other authorizing documents) and has, with respect
to each Zanova Employee Plan which is subject to ERISA reporting requirements,
provided copies of any Form 5500 reports filed for the last three plan years.
Any Zanova Employee Plan intended to be qualified under Section 401(a) of the
Code has either obtained from the Internal Revenue Service a favorable
determination letter as to its qualified status under the Code, including all
amendments to the Code effected by the Tax Reform Act of 1986 and subsequent
legislation, or has applied to the Internal Revenue Service for such a
determination letter prior to the expiration of the requisite period under
applicable Treasury Regulations or Internal Revenue Service pronouncements in
which to apply for such determination letter and to make any amendments
necessary to obtain a favorable determination. Zanova has also made available
Onvia with the most recent Internal Revenue Service determination letter issued
with respect to each such Zanova Employee Plan, and nothing has occurred since
the issuance of each such letter which could reasonably be expected to cause the
loss of the tax-qualified status of any Zanova Employee Plan subject to Code
Section 401(a).

               (c)     (i) None of the Zanova Employee Plans promises or
provides retiree medical or other retiree welfare benefits to any person; (ii)
there has been no "prohibited transaction," as such term is defined in Section
406 of ERISA and Section 4975 of the Code, with respect to any Zanova Employee
Plan; (iii) each Zanova Employee Plan has been administered in all material
respects in accordance with its terms and in compliance in all material respects
with the requirements prescribed by any and all statutes, rules and regulations
(including ERISA and the Code), and Zanova and each Subsidiary or ERISA
Affiliate have performed all material obligations required to be performed by
them under, are not in any material respect in default, under or violation of,
and have no knowledge of any material default or violation by any other party
to, any of the Zanova Employee Plans; (iv) neither Zanova nor any subsidiary or
ERISA Affiliate is subject to any liability or penalty under Sections 4976
through 4980 of the Code or Title I of ERISA with respect to any of the Zanova
Employee Plans; (v) all contributions required to be made by Zanova or any
subsidiary or ERISA Affiliate to any Zanova Employee Plan have been made on or
before their due dates and a reasonable amount has been accrued for
contributions to each Zanova Employee Plan for the current plan years; (vi) with
respect to each Zanova Employee Plan, no "reportable event" within the meaning
of Section 4043 of ERISA (excluding any such event for which the thirty (30) day
notice requirement has been waived under the regulations to Section 4043 of
ERISA) nor any event described in Section 4062, 4063 or 4041 of ERISA has
occurred; and (vii) no Zanova Employee Plan is covered by, and neither Zanova
nor any subsidiary or ERISA Affiliate has incurred or

                                     -19-
<PAGE>

expects to incur any material liability under Title IV of ERISA or Section 412
of the Code. With respect to each Zanova Employee Plan subject to ERISA as
either an employee pension plan within the meaning of Section 3(2) of ERISA or
an employee welfare benefit plan within the meaning of Section 3(1) of ERISA,
Zanova has prepared in good faith and timely filed all requisite governmental
reports (which were true and correct in all material respects as of the date
filed) and has properly and timely filed and distributed or posted all notices
and reports to employees required to be filed, distributed or posted with
respect to each such Zanova Employee Plan. No suit, administrative proceeding,
action or other litigation has been brought, or to the knowledge of Zanova is
threatened, against or with respect to any such Zanova Employee Plan, including
any audit or inquiry by the IRS or United States Department of Labor. Neither
Zanova nor any ERISA Affiliate is a party to, or has made any contribution to or
otherwise incurred any obligation under, any "multi-employer plan" as defined in
Section 3(37) of ERISA.

               (d)     With respect to each Zanova Employee Plan, Zanova has
complied in all material respects with (i) the applicable health care
continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the proposed regulations thereunder,
                             -----
(ii) the applicable requirements of the Family Leave Act of 1993 and the
regulations thereunder, and (iii) the applicable requirements of the Health
Insurance Portability and Accountability Act of 1996 ("HIPAA") and the temporary

regulations thereunder.

               (e)     Except as set forth in Schedule 3.8(e) of the Zanova
Disclosure Schedule, the consummation of the transactions contemplated in this
Agreement will not (i) entitle any current or former employee or other service
provider of Zanova or any other ERISA Affiliate to severance benefits or any
other payment (including, without limitation, unemployment compensation, golden
parachute or bonus), except as expressly provided in this Agreement, or (ii)
accelerate the time of payment or vesting of any such benefits, or (iii)
increase or accelerate any benefits or the amount of compensation due any such
employee or service provider.

               (f)     There has been no amendment to, written interpretation or
announcement (whether or not written) by Zanova or other ERISA Affiliate
relating to, or change in participation or coverage under, any Zanova Employee
Plan which would materially increase the expense of maintaining such Plan above
the level of expense incurred with respect to that Plan for the most recent
fiscal year included in the Zanova Financial Statements.

to the other party, if a court of competent jurisdiction or other Governmental
Entity shall have issued a nonappealable final order, decree or ruling or taken

days following receipt by the breaching party of written notice of such breach
by the other party;

                  (d)  by Onvia, by giving written notice to Zanova, if the
Closing shall not have occurred on or before July 31, 2000 by reason of the
failure of any condition precedent under Section 8.1 or 8.2 (unless the failure

stockholders or Affiliates, except as set forth in Section 9.3 and further
except to the extent that such termination results from the willful breach by
any such party of any of its representations, warranties or covenants set forth
in this Agreement.

         Section 9.3  Fees and Expenses.
                      -----------------

Merger within such budget and shall not enter into any agreement inconsistent
with such budget.

                  (b) If the Merger is consummated, all legal, accounting,
investment banking, broker's and finder's fees and expenses incurred by Zanova
or its stockholders in connection with the Merger shall be deemed expenses of
the stockholders of Zanova to the extent such fees and expenses exceed Three
Hundred Thousand Dollars ($300,000), and shall be borne by the stockholders of
Zanova to such extent and will not become obligations of Zanova. In addition,
Zanova may pay up to an additional Two Hundred Thousand Dollars ($200,000) of
such fees and expenses if and only if Zanova has at least such amount of
available cash on the Closing Date and such payment is made out of such
available cash. Zanova will make arrangements for the payments of such fees
acceptable to Onvia. Any such fees and expenses in excess of Three Hundred
Thousand Dollars ($300,000), or Five Hundred Thousand Dollars ($500,000) in the
aggregate if the additional Two Hundred Thousand Dollars ($200,000) is paid out
of available cash pursuant to this paragraph, incurred by Zanova shall be
recoverable from the Escrow Fund (as defined in Section 10.2) as Damages (as
defined in Section 10.1) without regard to the Indemnification Threshold or
Indemnification Deductible as contemplated in Section 10.3.

and Sub acknowledge and agree, and the Former Zanova Stockholders, by their
approval of this Agreement, agree that notwithstanding anything to the contrary

Article X and in the Depository Agreement. Notwithstanding the foregoing or
anything to the contrary contained in this Agreement, the indemnification

further, however, Onvia may bring claims against one or more Former Zanova

Stockholders' Agents and to the Depository Agent; provided, however, that after
an Officer's Certificate or Certificates for an aggregate amount equal to or
greater than the Indemnification Threshold in Damages has been delivered, Onvia
shall be entitled to receive Escrow Shares equal in value to the full amount of
Damages identified in such Officer's Certificate or Certificates for all amounts
in excess of Seventy Five Thousand Dollars ($75,000) (the "Indemnification
Deductible"); provided, however, that the Indemnification Deductible shall only

claim to which such item is related, the Depository Agent shall, subject to the

the Depository Agent shall make no delivery of Escrow Shares pursuant to Section
10.4 unless the Depository Agent shall have received written authorization from
the Stockholders' Agents to make such delivery. After the expiration of such
thirty (30) day period, the Depository Agent shall make delivery of the Escrow
Shares in the Escrow Fund in accordance with Section 10.4; provided, however,
that no such delivery may be made if the Stockholders' Agents shall object in a
written statement to the claim made in the Officer's Certificate, and such
statement shall have been delivered to the Depository Agent and to Onvia prior
to the expiration of such thirty (30) day period.

         Section 10.8   Resolution of Conflicts.
                        -----------------------

                  (a)   In case the Stockholders' Agents shall so object in
writing to any claim or claims by Onvia made in any Officer's Certificate, Onvia
shall have thirty (30) days to respond in a written statement to the objection
of the Stockholders' Agents. If after such thirty (30) day period there remains
a dispute as to any claims, the Stockholders' Agents and Onvia shall attempt in
good faith for thirty (30) days to agree upon the rights of the respective
parties with

                                     -47-
<PAGE>

respect to each of such claims. If the Stockholders' Agents and Onvia should so
agree, a memorandum setting forth such agreement shall be prepared and signed by
both parties and shall be furnished to the Depository Agent. The Depository
Agent shall be entitled to rely on any such memorandum and shall distribute the
Escrow Shares from the Escrow Fund in accordance with the terms of the
memorandum.
                  (b)   If no such agreement can be reached after good faith
negotiation, either Onvia or the Stockholders' Agents may, by written notice to
the other, demand arbitration of the matter unless the amount of the damage or
loss is at issue in pending litigation with a third party, in which event
arbitration shall not be commenced until such amount is ascertained or both
parties agree to arbitration; and in either such event the matter shall be
settled by arbitration conducted by three arbitrators. Within fifteen (15) days
after such written notice is sent, Onvia (on the one hand) and the Stockholders'
Agents (on the other hand) shall each select one arbitrator, and the two
arbitrators so selected shall select a third arbitrator. The decision of the
arbitrators as to the validity and amount of any claim in such Officer's
Certificate shall be binding and conclusive upon the parties to this Agreement,
and notwithstanding anything in Section 10.4, the Depository Agent shall be
entitled to act in accordance with such decision and make or withhold payments
out of the Escrow Fund in accordance with such decision.

                  (c)   Judgment upon any award rendered by the arbitrators
may be entered in any court having jurisdiction. Any such arbitration shall be
held in King County, Washington under the commercial rules then in effect of the
American Arbitration Association. The non-prevailing party to an arbitration
shall pay its own expenses, the fees of each arbitrator, the administrative fee
of the American Arbitration Association, and the expenses, including, without
limitation, the reasonable attorneys' fees and costs, incurred by the prevailing
party to the arbitration.

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

                  (a)   If this Agreement and the Merger are approved by the
requisite vote of Zanova's stockholders, effective upon such vote and without
any further act by any Former Zanova Stockholder, APPSWare Holdings, Inc. and
Richard Neuheisel shall be constituted and appointed as agents (the
"Stockholders' Agents") for and on behalf of the Former Zanova Stockholders to
 --------------------
give and receive notices and communications, to authorize delivery to Onvia of
the Escrow Shares or other property from the Escrow Fund in satisfaction of
claims by Onvia, to object to such deliveries, to agree to, negotiate, enter
into settlements and compromises of, and demand arbitration and comply with
orders of courts and awards of arbitrators with respect to such claims, and to
take all actions necessary or appropriate in the judgment of the Stockholders'
Agents for the accomplishment of the foregoing. All actions of the Stockholders'
Agents shall be taken jointly, not individually. Such agency may be changed by
the holders of a majority in interest of the Escrow Shares from time to time
upon not less than ten (10) days' prior written notice to Onvia. No bond shall
be required of the Stockholders' Agents, and the Stockholders' Agents shall
receive no compensation for services. Notices or communications to or from the
Stockholders' Agents shall constitute notice to or from each of the Former
Zanova Stockholders.

                  (b)   The Stockholders' Agents shall not be liable for any
act done or omitted hereunder as Stockholders' Agent while acting in good faith,
and any act done or omitted pursuant to the advice of counsel shall be
conclusive evidence of such good faith. The Former Zanova Stockholders shall
severally and pro rata, in accordance with their Pro Rata Portion, indemnify the
Stockholders' Agents and hold them harmless against any loss, liability or
expense incurred without gross negligence or bad faith on the part of the
Stockholders' Agents and arising out of or in connection with the acceptance or
administration of their duties hereunder under this Agreement or the Depository
Agreement.

                  (c)   The Stockholders' Agents shall have reasonable access
to information about Zanova and Onvia and the reasonable assistance of Zanova's
and Onvia's officers and employees for purposes of performing their duties and
exercising their rights under this Article X, provided that the Stockholders'
                                              --------
Agents shall treat confidentially and not disclose any nonpublic information
from or about Zanova or Onvia to anyone (except on a need to know basis to
individuals who agree to treat such information confidentially).

                        -----------------------------------
consent or instruction of the Stockholders' Agents shall constitute a decision
of all of the Former Zanova Stockholders for whom shares of Onvia Common Stock
otherwise issuable to them are deposited in the Escrow Fund and shall be final,
binding and conclusive upon each such Former Zanova Stockholder, and the
Depository Agent and Onvia may rely upon any decision, act, consent or
instruction of the Stockholders' Agents as being the decision, act, consent or
instruction of each and every such Former Zanova Stockholder. The Depository
Agent and Onvia are hereby relieved from any liability to any person for any
acts done by them in accordance with such decision, act, consent or instruction
of the Stockholders' Agents.

         Section 10.11  Claims. In the event Onvia becomes aware of a third-
                        ------
party claim which Onvia believes may result in a demand against the Escrow Fund,
Onvia shall promptly notify the Stockholders' Agents of such claim, and the
Stockholders' Agents and the Former Zanova Stockholders for whom shares of Onvia
Common Stock otherwise issuable to them are deposited in the Escrow Fund shall
be entitled, at their expense, to participate in any defense of such claim.
Onvia shall have the right in its sole discretion to settle any such claim;
provided, however, that Onvia may not effect the settlement of any such claim
without the consent of the Stockholders' Agents, which consent shall not be
unreasonably withheld. In the event that the Stockholders' Agents have consented
to any such settlement, the Stockholders' Agents shall have no power or
authority to object to the amount of any claim by Onvia against the Escrow Fund
for indemnity with respect to such settlement in the amount agreed to.
