                                   SECTION 4

                 Representations and Warranties of the Purchaser

         Purchaser hereby represents, warrants and covenants to and with the
Company as follows:

         4.1 Experience. Purchaser has substantial experience in evaluating and
investing in private placement transactions so that Purchaser is capable of
evaluating the merits and risks of Purchaser's investment in the Company.
Purchaser, by reason of its business or financial experience or the business or
financial experience of its professional advisors who are unaffiliated with and
who are not compensated by the Company or any affiliate or selling agent of the
Company, directly or indirectly, has the capacity to protect its own interests
in connection with the purchase of the Shares under this Agreement.

         4.2 Purchase Entirely for Own Account. This Agreement is made with the
Purchaser in reliance upon the Purchaser's representation to the Company, which
by the Purchaser's execution of this Agreement the Purchaser hereby confirms,
that the Shares to be received by the Purchaser will be acquired for investment
for the Purchaser's own account, not as a nominee or agent, and not with a view
to the resale or distribution of any part thereof, and that the Purchaser has no
present intention of selling, granting any participation in or otherwise
distributing the same. By executing this Agreement, the Purchaser further
represents that it does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such
person or to any third person, with respect to any of the Shares.

         4.3 Restricted Securities. The Purchaser understands that the Shares it
is purchasing are characterized as "restricted securities" under the U.S.
federal securities laws inasmuch as they are being acquired from the Company in
a transaction not involving a public offering and that under such laws and
applicable regulations such Shares may be resold without registration under the
Securities Act of 1933, as amended (the "Securities Act"), only in certain
limited circumstances. In the absence of an effective registration statement
covering the Shares or an available exemption from registration under the
Securities Act, the Shares must be held indefinitely. In this connection, the
Purchaser represents that it is familiar with Rule 144 under the Securities Act,
as presently in effect, and understands the resale limitations imposed thereby
and by the Securities Act, including without limitation the Rule 144 condition
that current information about the Company be available to the public, and
further understands that such information is not now available.

         4.4 Access to Data. Purchaser and its representatives have met with
representatives of the Company and have had the opportunity to ask questions of,
and receive answers from, said representatives concerning the Company and the
terms and conditions of this transaction as well as to obtain any information
requested by Purchaser. Any questions raised by Purchaser or its representatives
concerning the transaction have been answered to the satisfaction of Purchaser
and its representatives. Purchaser's decision to purchase the Shares is based in
part on the answers to such questions as Purchaser and its representatives have
raised concerning the transaction and on its own evaluation of the risks and
merits of the purchase and the Company's proposed business activities.
<PAGE>

         4.5 Accredited Investor. The Purchaser is either (i) a "qualified
institutional buyer" within the meaning of such term under paragraph (a) of Rule
144A under the Securities Act, or (ii) a large institutional "accredited
investor" within the meaning of such term under paragraph (a)(1), (a)(2),
(a)(3), (a)(7) or (a)8 of Rule 501 of Regulation D under the Securities Act as
further discussed in SEC No-Action Letter regarding Black Box Incorporated, 1992
WL 55818 (S.E.C.), dated February 28, 1992 and SEC No-Action Letter regarding
Black Box Incorporated, 1990 WL 286633 (S.E.C.), dated June 26, 1990.

         4.6 Further Limitations on Disposition. Without in any way limiting the
representations set forth above, the Purchaser further agrees not to make any
disposition of all or any portion of the Shares unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by this Section
4, and: (a) There is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or (b) (i) The Purchaser shall
have notified the Company of the proposed disposition and shall have furnished
the Company with a detailed statement of the circumstances surrounding the
proposed disposition, and (ii) if requested by the Company, the Purchaser shall
have furnished the Company with an opinion of counsel, reasonably satisfactory
to the Company that such disposition will not require registration of such
Shares under the Securities Act. It is agreed that the Company will not require
opinions of counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

         Notwithstanding the provisions of subsections (a) and (b) above, no
such registration statement or opinion of counsel shall be necessary for a
transfer by the Purchaser, if it is a partnership, to a partner of such
partnership or a retired partner of such partnership who retires after the date
hereof, or to the estate of any such partner or retired partner or the transfer
by gift, will or intestate succession of any partner to his or her spouse or to
the siblings, lineal descendants or ancestors of such partner or his or her
spouse, if the transferee agrees in writing to be subject to the terms hereof to
the same extent as if he or she were the original Purchaser hereunder.

         4.7 Legends. It is understood that the certificates evidencing the
Shares may bear one or all of the following legends: (a) These securities have
not been registered under the Securities Act of 1933, as amended (the "Act").
They may not be sold, offered for sale, pledged or hypothecated in the absence
of a registration statement in effect with respect to the securities under such
Act or an opinion of counsel satisfactory to the Company that such registration
is not required or unless sold pursuant to Rule 144 of such Act.

         (b) Any legend required by the laws of the State of Delaware, including
any legend required by the Delaware General Corporation Law.

         4.8 Further Representations by Foreign Investors. If it is not a United
States person, the Purchaser hereby represents that it has satisfied itself as
to the full observance of the laws of its jurisdiction in connection with any
purchase of the Shares or any use of this Agreement, including (i) the legal
requirements within its jurisdiction for the purchase of the Shares, (ii) any
foreign exchange restrictions applicable to such purchase, (iii) any
governmental or other consents that may need to be obtained and (iv) the income
tax and other tax consequences, if any, that may be relevant to the purchase,
holding, redemption, sale or transfer of the Shares. The Purchaser further
represents that its purchase and payment for, and its continued beneficial
ownership of the Shares, will not violate any applicable securities or other
laws of its jurisdiction

         4.9 Organization; Authorization. Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of Washington.
All corporate action on the part of Purchaser, its officers, directors and
stockholders necessary for the authorization, execution, delivery and
performance of all of its obligations under this Agreement has been taken or
will be taken prior to the Closing. This Agreement when executed and delivered
by the Purchaser will constitute a valid and legally binding obligation of the
Purchaser, enforceable in accordance with its terms.
