Mr. Buckley:

      You agree that, until November 26, 2003, unless such shall have been
specifically invited in writing by Onvia.com, Inc. (the "COMPANY") or as
otherwise contemplated by the possible disposition of all or a portion of its
shares of the common stock of the Company to an undesignated party, neither you
nor any of your affiliates (as such term is defined under the Securities
Exchange Act of 1934, as amended (the "1934 ACT")) will in any manner, directly
or indirectly: (a) effect or seek, offer or propose (whether publicly or
otherwise) to effect, or cause or in any way assist any other person to effect
or seek, offer or propose (whether publicly or otherwise) to effect, (i) any
acquisition of any securities (or beneficial ownership thereof) or assets of the
Company or any of its subsidiaries, (ii) any tender or exchange offer, merger or
other business combination involving the Company or any of its subsidiaries,
(iii) any recapitalization, restructuring, liquidation, dissolution or other
extraordinary transaction with respect to the Company or any of its
subsidiaries, or (iv) any "solicitation" of "proxies" (as such terms are used in
the proxy rules of the Securities and Exchange Commission) or consents to vote
any voting securities of the Company; (b) form, join or in any way participate
in a "group" (as defined under the 1934 Act) with respect to the Company; (c)
otherwise act, alone or in concert with others, to seek to control or influence
the management, Board of Directors or policies of the Company; (d) take any
action which might force the Company to make a public announcement regarding any
of the types of matters set forth in (a) above; or (e) enter into any
discussions or arrangement with any third party with respect to any of the
foregoing. You also agree during such period not to request the Company or any
of its Representatives, directly or indirectly, to amend or waive any provision
of this paragraph (including this sentence). As used in this letter, the
Company's "REPRESENTATIVES" shall include the directors, officers, employees,
agents, partners or advisors of the Company and its subsidiaries and affiliates
(including, without limitation, attorneys, accountants, consultants, bankers and
financial advisors).

      It is understood and agreed that no failure or delay by the Company in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
future exercise thereof or the exercise of any other right, power or privilege
hereunder.

      It is further understood and agreed that money damages would not be a
sufficient remedy for any breach of this letter agreement by you and that the
Company shall be entitled to equitable relief, including injunction and specific
performance, as a remedy for any such breach. Such remedies shall not be deemed
to be the exclusive remedies for a breach by you of this letter agreement but
shall be in addition to all other remedies available at law or equity. In the
event of litigation relating to this letter agreement, if a court of competent
jurisdiction determines that you have breached this letter agreement, then you
shall be liable and pay to the Company the reasonable legal fees incurred by the
Company in connection with such litigation, including any appeal therefrom.

      This letter agreement is for the benefit of the Company, its
Representatives and their respective directors, officers, stockholders, owners,
affiliates, and agents (all of the foregoing, other than the Company as a direct
party hereto, being expressly designated as third party beneficiaries of this
letter agreement), and shall be governed by and construed in accordance with the
laws of the State of Washington (the "SUBJECT STATE") applicable to agreements
made and to be performed entirely within the Subject State.

      This letter agreement contains the entire agreement between the Company
and you regarding its subject matter and supersedes all prior agreements,
understandings, arrangements and discussions between the Company and you
regarding such subject matters.

      This letter agreement may be signed in counterparts, each of which shall
be deemed an original but all of which shall be deemed to constitute a single
instrument.


                                       2

      Please confirm your agreement with the foregoing by having a duly
authorized officer of your organization sign and return one copy of this letter
to the undersigned, whereupon this letter agreement shall become a binding
agreement between you and the Company.

                                          Very truly yours,


                                          Onvia.com, Inc.
