the Transaction Documents have been duly authorized by all necessary corporate
action on the part of the Company. The Company's Board of Directors has approved
the Certificate of Designation. This Agreement has been, and when executed and
delivered at the Closing the other Transaction Documents will be, duly executed
and delivered by the Company and constitutes, or when executed and delivered at
the Closing will constitute, valid and binding obligations of the Company,
enforceable against it in accordance with their respective terms, except as may

similar laws and equitable principles relating to or limiting creditors' rights
generally.

                           3.4.2    The execution, delivery and, subject to
obtaining the consents set forth in SCHEDULE 3.4, performance by the Company of
the Transaction Documents and the consummation of the transactions contemplated
thereby will not, except in each case where the effect of non-compliance could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, (i) modify, breach or constitute grounds for the occurrence or
declaration of a default under or give rise to a right to terminate any
agreement, license, indenture, undertaking or other instrument to which the
Company is a party or by which it or any of its assets may be bound or affected,
(ii) violate any provision of law or any regulation or any order, judgment, or
decree of any court or other agency of government to which the Company is
subject, (iii) violate any provision of the Amended and Restated Certificate of
Incorporation (the "CERTIFICATE OF INCORPORATION") or Bylaws of the Company, or

                  3.5 STATE TAKEOVER STATUTES. The Strategic Investment
Committee of the Board, by a unanimous written consent dated June 8, 2000, has
unanimously approved the terms of this Agreement and the other Transaction
Documents and the consummation of the transactions contemplated hereby and
thereby (including without limitation the sale and issuance to Purchaser of the
Shares and the Vulcan Warrant pursuant to this Agreement) and such approval
constitutes approval of such transactions by the Board under the provisions of
Section 203 of the Delaware General Corporation Law, as amended (the "DGCL"),
and constitutes all actions necessary to ensure that the restrictions contained
in Section 203 of the DGCL will not apply to Purchaser in connection with or
following such transactions. To its knowledge, no other state takeover statute
is applicable to the transactions contemplated by this Agreement and the other
Transaction Documents.

provisions of this Agreement, the Shares will be validly issued, fully paid and
nonassessable, and will be free of any Liens created by or through the Company,
other than restrictions on transfer under state and/or federal securities laws.
The sale of the Shares is not subject to any preemptive rights or rights of
first refusal that have not been properly waived or complied with. Upon the
filing with the Delaware Secretary of State and effectiveness of the Certificate
of Designation, the rights, privileges and preferences of the Series A Preferred
Stock set forth in the Certificate of Designation will constitute the valid and
binding obligations of the Company, enforceable against it in accordance with
their respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium and other similar laws and equitable principles

issuable upon exercise of the Vulcan Warrant against payment therefore, when so
issued, will be validly issued, fully paid and nonassessable, and will be free
of any Liens created by or through the Company, other than restrictions on
transfer under state and/or federal securities laws. Issuance of such shares of
Common Stock is not subject to any preemptive rights or rights of first refusal
that have not been properly waived or complied with.

                  3.7 GOVERNMENTAL CONSENT. No consent, approval or
authorization of, or declaration or filing with, any governmental authority on
the part of the Company is required for the execution and delivery of the

thereunder, and (y) did not at the time they were filed, contain any untrue

presently conducted, except where a failure to own or license Intellectual
Property Rights could not, either individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect on the Company.

                           3.13.2   To the Company's knowledge, the operation of
the business of the Company does not, and except as identified on SCHEDULE 3.13,

entity is infringing or misappropriating any Intellectual Property Rights owned
or licensed by the Company or engaging in other conduct other than in the
ordinary course of business that may diminish or undermine such Intellectual

<PAGE>

Governmental Body in any audit or examination which reasonably could be expected
to result in a proposed deficiency, penalty or interest for any other period,
which could reasonably be expected to have a Material Adverse Effect on the
Company.

                           3.15.3   There are no outstanding agreements or
waivers extending the statutory period of limitation applicable to any Tax
Returns required to be filed by, or which include or are treated as including,

                           3.15.5   All material elections with respect to Taxes
affecting the Company as of the date hereof are set forth in SCHEDULE 3.15. No

includible in any consolidated or unitary Tax Return with any corporation other
than such a return of which the Company is the common parent corporation.

required to make any material adjustment under section 481(a) of the Internal
Revenue Code of 1986, as amended (the "CODE").

                           3.15.9   "TAX" or "TAXES", as the context may

subject to any Liens, except for (a) immaterial Liens which arise in the
ordinary course of business (including without limitation Liens from current
taxes not yet due and payable), and (b) Liens which individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect on
the Company or its material properties. All material leases, subleases,
conditional sale contracts and other agreements pursuant to which the Company
leases or otherwise uses real or personal property (collectively, "LEASES") are
in good standing and are valid and effective in accordance with their respective
terms. The Company has performed its obligations in all material respects to
date under all such Leases.

                  3.17 EMPLOYEE BENEFIT PLANS. Except as listed in SCHEDULE 3.17
or as described in the SEC Reports or as could not, either individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect, the
Company does not maintain, sponsor, or contribute to any program or arrangement
that is an "employee welfare benefit plan," as that term is defined in Section
3(1) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or any similar employment, severance or other arrangement or policy
of the Company (whether written or oral) providing for insurance coverage
(including self-insured arrangements), workers' compensation, disability
benefits, supplemental unemployment benefits, vacation benefits, fringe benefits
or for qualified deferred compensation, bonuses, stock options, stock
appreciation or other forms of incentive compensation or post-retirement
insurance, compensation or benefits (a "PLAN"). Except as listed in SCHEDULE
3.17, neither the Company nor any member of the same controlled group of
businesses as the Company within the meaning of Section 4001(a)(14) of ERISA (an
"ERISA AFFILIATE") maintains or is obligated to contribute to, or has ever
maintained or been obligated to contribute to, any "pension plan" within the
meaning of Section 3(2) of ERISA, or any "multiemployer plan" within the meaning
of Section 3(37) of ERISA (a "PENSION PLAN"). Each Plan which is subject to
ERISA is in compliance with ERISA, except where the failure to so comply would
not reasonably be expected to have a Material Adverse Effect. None of the Plans
provides or provided post-retirement medical or health benefits, except as
required by the health care continuation requirements of the Consolidated
Omnibus Reconciliation Act of 1985, as amended, or other applicable legal
requirement and except for coverage the full cost of which is paid by the
participant or beneficiary. None of the Plans is or was a "welfare benefit
fund," as defined in Section 419(e) of the Code, or an organization described in
Sections 501(c)(9) or 501(c)(20) of the Code. The Company is not and never has
been a party to any collective bargaining agreement. Except as would not
reasonably be expected to have a Material Adverse Effect and except as set forth
on SCHEDULE 3.17, the Company has not announced or otherwise made any commitment
to create any new Plan or amend any existing Plan, and neither the Company nor
any ERISA Affiliate has announced or otherwise made any commitment to create or
begin contributing to any Plan or Pension Plan or amend any existing Plan or
Pension Plan, except for amendments to existing Plans and Pension Plans that are
required by applicable law (including provisions of the Code relating to the
intended tax treatment of any such Plan or Pension Plan). All contributions
required to be made under the terms of each Plan have been timely made. Each
Plan which is required to comply with the provisions of Sections 4980B and 4980C
of the Code, or with the requirements referred to in


                                      -9-
<PAGE>

Section 4980D(a) of the Code, has complied in all material respects. Each Plan
intended to meet the requirements for tax-favored treatment under Part III of
Subchapter B of Chapter 1 of the Code meets such requirements. Except as
described in SCHEDULE 3.17, the execution and performance of this Agreement will
not (i) result in any obligation or liability (with respect to accrued benefits
or otherwise) of the Company to any Plan, or any present or former employee of
the Company, (ii) be a trigger event under any Plan that will result in any
payment (whether of severance pay or otherwise) becoming due to any present or
former employee, officer, director, stockholder, contractor, or consultant, or
any of their dependents, or (iii) except as otherwise expressly contemplated by
this Agreement, accelerate the time of payment or vesting, or increase the
amount, of compensation due from the Company to any employee, officer, director,
stockholder, contractor, or consultant of the Company.

                  3.18 YEAR 2000 COMPLIANCE. The Company has completed its
assessment of all current versions (including products and services currently
operating or under development) of its information technology systems (including
systems utilized in the operation of its Internet sites) and believes they are
year 2000 compliant. The Company has made appropriate inquiries of its key
vendors and suppliers and has been assured that such persons have also taken
appropriate actions to assure that there shall be no material adverse change to
its business and electronic systems related to year 2000 issues. Based upon the
information provided to the Company and its own internal assessment, the Company
does not believe that its year 2000 issues will have a Material Adverse Effect
on the Company.

                  3.19 FINDERS' FEES. There is no investment banker, broker,
finder or other intermediary that has been retained by or is authorized to act
on behalf of Company who might be entitled to any fee or commission upon
consummation of the transactions contemplated by this Agreement and each of the
other Transaction Documents other than Credit Suisse First Boston Corporation.

         4. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby
represents and warrants to the Company as follows:

                  4.1 ORGANIZATION AND QUALIFICATION. Purchaser is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Washington. Purchaser has all requisite corporate power and authority
to conduct its business as currently conducted and to enter into and to carry
out and perform its obligations under the Transaction Documents.

                  4.2 DUE EXECUTION, DELIVERY AND PERFORMANCE OF THE AGREEMENT.
The execution, delivery and performance of the Transaction Documents have been
duly authorized by all necessary corporate action on the part of Purchaser. This
Agreement has been, and when executed and delivered at the Closing the other
Transaction Documents will be, duly executed and delivered by Purchaser and
constitutes, or when executed and delivered at the Closing will constitute,
valid and binding obligations of Purchaser, enforceable against it in accordance
with their respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium and other similar laws and equitable principles
relating to or limiting creditors' rights generally.


                                      -10-
<PAGE>

                  4.3 EVALUATION; PURCHASE FOR INVESTMENT, ILLIQUID INVESTMENT.
Purchaser has been furnished any and all materials relating to the Company and
its Affiliates (as defined below) and the offering of the Shares and the Vulcan
Warrant, and the shares of Common Stock issuable upon conversion of the Shares
and upon exercise of the Vulcan Warrant (collectively, the "COMMON SHARES"),
that Purchaser has requested and Purchaser has been afforded the opportunity to
obtain any additional information necessary to verify the accuracy of any such
information. Purchaser is a sophisticated investor capable of evaluating the
merits and risks of the purchase of the Shares, the Vulcan Warrant and the
Common Shares. Purchaser is purchasing the Shares and the Vulcan Warrant for its
own account as principal, for investment and not with a view to the resale or
distribution of all or any part thereof. Purchaser recognizes that the Shares,
the Vulcan Warrant and the Common Shares have not been registered under
applicable Federal or State securities laws, and that such Shares, the Vulcan
Warrant and the Common Shares are being offered and sold in reliance upon the
exemptions from registration provided in the Securities Act and applicable
exemptions under State securities laws. Purchaser is an accredited investor (as
that term is defined in Regulation D under the Securities Act) and has the
economic ability to maintain its investment in such Shares, the Vulcan Warrant
and the Common Shares for an indefinite period of time. For purposes of this
Agreement, "AFFILIATE" shall have the meaning set forth in Rule 501(b) under the
Securities Act.

                  4.4 FINDERS' FEES. Except for Yagemann & Co. LLC, there is no
investment banker, broker, finder or other intermediary that has been retained
by or is authorized to act on behalf of Purchaser who might be entitled to any
fee or commission upon consummation of the transactions contemplated by this
Agreement and each of the other Transaction Documents.

                  4.5 FINANCIAL CONDITION. As of the date hereof, Purchaser has
sufficient resources to fulfill its financial obligations under this Agreement
and the transactions contemplated hereby.

                  4.6 INTERESTED STOCKHOLDER. In each case within the meaning of
Section 203 of the DGCL:

                           (a)      at no time since immediately prior to the
time the Company's Board of Directors approved the transactions contemplated by
this Agreement through the time of the signing hereof, has Purchaser or any
"affiliate" or "associate" of Purchaser "owned" fifteen percent (15%) or more of
the Company's "voting stock"; and

                           (b)      there are no facts known to Purchaser or any
"affiliate" or "associate" of Purchaser, that have not been disclosed to the
Company that relate to whether Purchaser or any "affiliate" or "associate" of
Purchaser, directly or indirectly, through one or more intermediaries,
"controls" or "controlled" or is or was "controlled by" or is or was "under
common control with" the Company.

         5. COVENANTS OF THE COMPANY. The Company hereby covenants and agrees
with Purchaser as follows:

                  5.1      ADDITIONAL ISSUANCES; SUBSCRIPTION RIGHT.

                           5.1.1    At any time after the date of the Closing,
so long as Purchaser (together with its Affiliates) holds of record or
beneficially owns at least fifty percent (50%) of the Shares issued in the
Closing (the "AGREED PERCENTAGE"), in the event the Company shall issue (an
"ADDITIONAL ISSUANCE") any capital stock, including securities of any type that
are, or may become, convertible into or exercisable or exchangeable for capital
stock of the Company (the "ADDITIONAL SECURITIES"), Purchaser shall have the
right to subscribe for and to purchase (the "SUBSCRIPTION RIGHT") that number of
Additional Securities such that Purchaser holds the same percentage of the
Company's outstanding capital stock immediately prior to and immediately
following the Additional Issuance (the "PRO RATA SHARE"); PROVIDED, HOWEVER,
that this Section 5.1 shall not apply to shares issued:

                           (a)      to employees, officers or directors of, or
consultants or advisors to the Company or any subsidiary, pursuant to stock
purchase, the Company Equity Incentive Plans, the Director Option Plan, the 1997
Employee Stock Purchase Plan or other equity plans or arrangements approved by
the Board;

                           (b)      pursuant to any options, warrants,
conversion rights or other rights or agreements outstanding as of the date of
this Agreement or pursuant to the conversion of the shares of Series A Preferred
Stock or pursuant to the exercise of the Vulcan Warrant;

                           (c)      in connection with any stock split, stock
dividend or recapitalization by the Company; or

                           (d)      pursuant to any equipment leasing
arrangement or debt financing from a bank or similar financial institution, not
to exceed 100,000 shares of Common Stock in the aggregate.

                           5.1.2    Notwithstanding anything to the contrary
contained herein, in the event Purchaser elects to exercise its Subscription
Right as a result of (i) an underwritten public offering of Additional
Securities, (ii) the offering of Additional Securities to the Company's joint
venture partners in exchange for interests in the relevant joint venture, or
(iii) the offering of Additional Securities in connection with an acquisition of
a business or assets or a strategic alliance, then (x) the number of shares of
the Company's capital stock to be purchased by Purchaser shall not reduce the
number of shares of capital stock to be sold by the Company in such transaction
and (y) Purchaser's Pro Rata Share shall be determined based on the number of
shares of the Company's outstanding capital stock as would be outstanding after
giving effect to the proposed transactions.

                           5.1.3    If the Company proposes an Additional
Issuance, the Company shall, at least ten (10) business days prior to the
proposed closing date of such issuance, give written notice to Purchaser and
offer to sell to Purchaser its Pro Rata Share of the Additional Securities at
the lowest price per share, and otherwise on the same terms and


                                      -12-
<PAGE>

conditions (or, if the nature of the transaction involves an exchange of assets
or securities which cannot be delivered by Purchaser, then for cash with an
equivalent fair market value (as agreed upon by the Company and Purchaser, and
if they cannot agree, as determined by an independent investment banking firm
mutually agreeable to both parties)), offered (or proposed to be offered) to
other investors. Such notice shall describe the type of Additional Securities
which the Company is offering to Purchaser, the price of the Additional
Securities and the general terms upon which the Company will issue same.
Purchaser shall have five (5) business days from the date of receipt of any such
notice to agree to purchase its Pro Rata Share of such Additional Securities for
the price and upon the general terms specified in the notice (except with
respect to Subscription Rights in connection with an underwritten public
offering, in which case Purchaser's shares will be issued in a simultaneous
private placement at a purchase price net of the underwriting commission) by
giving written notice to the Company and stating whether it will exercise the
Subscription Right and in the case the Subscription Right is exercised,
specifying the quantity of Additional Securities to be purchased. If Purchaser
elects to exercise its Subscription Right, the sale and issuance of the
Additional Securities which Purchaser has elected to purchase shall be effected
concurrently with the closing of the issuance of securities which gave rise to
Purchaser's right to buy such securities. Notwithstanding the foregoing, in the
event of an exercise of the Subscription Right, such purchase by Purchaser may
only occur after compliance with all governmental regulations, including but not
limited to the expiration or early termination of the applicable waiting periods
under the HSR Act, if applicable, which may be subsequent to the consummation of
the transaction which gave rise to the Subscription Right.

                  5.2 MOST FAVORED NATION. So long as Purchaser (together with
its Affiliates) holds the Agreed Percentage, the Company shall offer and make
available to Purchaser and its Affiliates licensing and business arrangements
relating to the Company's technologies, products and services, or any
combination thereof, on a "most favored nation" basis (i.e., on terms and
conditions at least as favorable as those agreed to with any third party for
similar technologies, products and services at substantially the same level of
purchase or other financial commitment). From time to time upon Purchaser's
request, the Company shall provide Purchaser or its Affiliates with information
regarding such technologies, products and services and the terms and conditions
on which they are being offered or have been made available to any third party.
Within sixty days after the end of each calendar year, the Company shall provide
a certificate to Purchaser, signed by the Company's Chief Financial Officer,
certifying that the Company has complied with its obligations under this Section
5.2. Purchaser shall have the right, no more than twice each calendar year, to
request any certified public accountant, during normal business hours, to
examine, audit and reproduce all or part of the books of account and all other
records, documents and materials in the possession or under the control of the
Company with respect to this Section 5.2. Such materials will be provided to the
designated certified public accountant under a non-disclosure agreement for the
sole purpose of verifying that the Company has complied with its obligations
under this Section 5.2. The costs and expenses of the certified public
accountant shall be paid by Purchaser; PROVIDED, HOWEVER, that if the certified
public accountant determines that the Company has not complied with its
obligations under this Section 5.2, such costs and expenses will be paid by the
Company.


                                      -13-
<PAGE>

                  5.3 BOARD SIZE. So long as Purchaser (together with its
Affiliates) holds the Agreed Percentage, the Company shall not increase the size
of the Board of Directors of the Company to greater than seven (7) members
without the written consent of Purchaser.

         6.       COVENANTS OF PURCHASER. Purchaser hereby covenants and
agrees with the Company that Purchaser will not sell or otherwise transfer
any Shares unless such sale or transfer is made under an effective Securities
Act registration statement or pursuant to an available exemption from the
registration requirements of the Securities Act and Purchaser shall have
delivered to the Company an opinion of securities counsel to Purchaser, in
form and substance reasonably satisfactory to the Company, to the forgoing
effect. Each certificate representing any Shares shall contain a legend to
the following effect:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "SECURITIES ACT"), AND MAY NOT BE SOLD OR OTHERWISE
                  TRANSFERRED UNLESS SUCH SALE OR TRANSFER IS MADE UNDER AN
                  EFFECTIVE SECURITIES ACT REGISTRATION STATEMENT OR PURSUANT TO
                  AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
                  THE SECURITIES ACT.

         Notwithstanding the foregoing, certificates issued after the date
hereof and representing Shares shall not contain the foregoing legend to the
extent that Purchaser shall have delivered to the Company an opinion of
securities counsel to Purchaser, in form and substance reasonably satisfactory
to the Company, to the effect that the statements made in such legend are no
longer relevant.

         7.       ADDITIONAL COVENANTS OF THE PARTIES.

                  7.1      BOARD COMPOSITION.

                           7.1.1    The Company shall set the number of the
members of the Board of Directors at seven. The Purchaser Director (as defined
below) shall be entitled to serve on the Executive Committee (if any), the
Planning Committee (if any), the Steering Committee (if any), the Nominating
Committee (if any) or any other committee of the Board of Directors that is
similar to any of the foregoing and, upon election of the Purchaser Director,
the Company shall take all action necessary to cause the Purchaser Director to
be on any such committees of the Board of Directors.

                           7.1.2    Pursuant to the Certificate of Designation,
immediately upon expiration or early termination of the waiting period under the
HSR Act applicable to the transactions contemplated hereby, holders of a
majority of the outstanding shares of Series A Preferred Stock shall be entitled
to elect one (1) director to serve on the Board of Directors of the Company. The
Company shall, as soon as practicable after such time, take all such action as
may be required to cause the Purchaser Director to be appointed or elected to
the Board of Directors, whether by appointment by the Board of Directors of a
nominee designated by Purchaser, through calling a special meeting of the
holders of shares of the Series A Preferred Stock to elect such director to the
Board or otherwise, and shall take all


                                      -14-
<PAGE>

action necessary to cause such individual to be elected, including either
increasing the size of the Board or securing the resignation of an incumbent
director or both. The member of the Board of Directors elected by the holders of
the Series A Preferred Stock is referred to as the "PURCHASER DIRECTOR".

                  7.2      ANNUAL OPERATING AND CAPITAL EXPENDITURE BUDGETS;
CONSULTATION.

                           7.2.1    After the Closing and for so long as
Purchaser (together with its Affiliates) holds the Agreed Percentage, (i) the
Company shall not operate without or approve any Annual Budget without the
consent of the Board of Directors, and (ii) on an annual basis, the management
of the Company shall prepare and submit to the Board of Directors, an Annual
Budget. As defined herein the "ANNUAL BUDGET" refers to the annual operating
budget (comprised of quarterly projected statements of revenue and expenses
(including capital expenditures) for the current calendar year and projected
statements of revenues and expenses for the following two (2) calendar years).
On or about the end of each quarter, the management of the Company shall prepare
an updated version of the Annual Budget, covering the remaining quarters of the
year for such Annual Budget. In addition to the foregoing, the management of the
Company may not, without the approval of the Board of Directors, issue any debt
or equity securities of the Company; PROVIDED, HOWEVER, that the foregoing
approval requirement shall not apply to the issuances of securities set forth in
the proviso to Section 5.1.1.

                  7.2.2 (a) After the Closing and for so long as Purchaser
(together with its Affiliates) holds the Agreed Percentage, the Company shall
consult in good faith with Purchaser with respect to each of the following
(each, a "PROPOSAL"): (i) the Annual Budget; (ii) any proposed sale, lease,
transfer or other disposition of assets (including, without limitation, by
merger) having a fair market value of at least 30% of the fair market value of
the assets of the Company and its subsidiaries on a consolidated basis (other
than a Takeover Proposal (as defined below)); (iii) any Takeover Proposal; (iv)
any proposed acquisition by the Company or any subsidiary thereof of another
entity or business whether by means of a purchase of equity interests or the
purchase of all or substantially all of the assets of such entity or business or
by merger, consolidation, reorganization, issuance or exchange of securities or
otherwise where the consideration involved (including, without limitation,
non-cash consideration) has a value of at least $50,000,000; and (v) any
proposed issuance of any debt or equity securities of the Company (other than
the issuances of securities set forth in the proviso to Section 5.1.1). The
Company shall provide Purchaser with written notice (a "CONSULTATION NOTICE") of
each Proposal, which Consultation Notice shall, (a) in the case of any Proposal
described in clause (ii), (iv) or (v) above, describe in reasonable detail the
terms and conditions of the transaction, including the identity of the person or
entity and its Affiliates that will be a party to the proposed transaction and
the consideration that the Company may receive in respect of such transaction,
and shall include copies of the material documents and agreements relating
thereto, (b) in the case of the Annual Budget, shall include a copy of the
proposed Annual Budget, and (c) in the case of any proposal described in clause
(iii) above, notify Purchaser that (i) the Company has received or proposes to
enter into negotiations or discussions with respect to a Takeover Proposal, (x)
the type of Takeover Proposal, (y) if the person or entity making the Takeover
Proposal or with which the Company proposes to enter into negotiations or
discussions is


                                      -15-
<PAGE>

proposing a transaction involving the use by such person or entity of cash
consideration, (A) whether the Takeover Proposal will be Fully Financed (as
defined below) at the time the Board of Directors may approve the Takeover
Proposal or (B) if the Takeover Proposal will not be Fully Financed, the
identity of such person or entity and (z) if the person or entity making the
Takeover Proposal or with which the Company proposes to enter negotiations or
discussions is proposing a transaction involving the use by such person or
entity of non-cash consideration, the identity of such person or entity and the
form of consideration proposed to be used. The cash consideration to be
delivered under a Takeover Proposal will be "FULLY FINANCED" for purposes hereof
if either (i) the person or entity making the Takeover Proposal has committed
financing for such Takeover Proposal or (ii) such person or entity is a publicly
traded entity with an equity market capitalization of at least 300% of the
equity market capitalization of the Company. Purchaser shall have a period of
five (5) business days following receipt of a Consultation Notice (the
"CONSULTATION PERIOD") to review and consider the Proposal described therein and
to consult with the Company with respect thereto. In addition to the
Consultation Notice, the Company shall promptly provide to Purchaser such
additional information regarding the Proposal (other than a Takeover Proposal)
as Purchaser may reasonably request. The Company shall not approve or consummate
any Proposal without first having consulted with Purchaser regarding the same in
accordance with this Section 7.2. "TAKEOVER PROPOSAL" shall mean that the
Company proposes to enter into negotiations or discussions with any person or
entity (other than an Affiliate of Purchaser) regarding (i) a proposed sale of
all or substantially all of the Company's assets, (ii) a proposed sale or
issuance of the Company's equity securities resulting in any person or group (as
defined in Section 13(d)(3) of the Exchange Act) owning a majority of the
outstanding shares of Common Stock of the Company, or (iii) a proposed merger,
consolidation, business combination or other similar transaction.

                           (b)      Without limiting the generality of the
foregoing, in connection with any Proposal that constitutes a Takeover Proposal,
the Company shall not accept or enter into or agree to accept or enter into any
agreement concerning such Proposal nor issue any securities or agree to pay a
termination or break-up fee in connection with such Proposal during the
Consultation Period, and the Company will afford Purchaser an opportunity to
discuss with the Company what, if any, response Purchaser may desire to make
with respect to such Proposal. If after the delivery of the Consultation Notice,
the person or entity making the Takeover Proposal and the Company determine to
change the form of consideration or the Fully Financed status of the Takeover
Proposal changes, the Company will provide Purchaser with another Consultation
Notice (which will commence a new Consultation Period (as defined above)). The
Company shall not provide any non-public information to any person or entity
making a Proposal that constitutes a Takeover Proposal unless (a) the Company
shall simultaneously provide such information to Purchaser and (b) the Company
has provided such non-public information pursuant to a non-disclosure agreement
with terms which are at least as restrictive as the nondisclosure agreement
heretofore entered into between the Company and Purchaser.

                           (c)      Any information provided to Purchaser
pursuant to this Section 7.2.2 shall be treated as confidential information of
the Company. Purchaser shall not disclose any such information to any other
person or entity except as otherwise permitted pursuant to that certain
Confidentiality Agreement between Purchaser and the


                                      -16-
<PAGE>

Company dated as of March 20, 2000 and shall not use any such confidential
information for any purpose other than for the purposes set forth in this
Section 7.2.2 and for the purposes of formulating any response or proposal that
Purchaser may desire to make in response thereto.

                  7.3 REGULATORY APPROVAL; HSR FILINGS. The Company and
Purchaser shall use commercially reasonable efforts to file, as soon as
practicable after the date of this Agreement, all notices, reports and other
documents required to be filed with any federal, state, local, municipal,
foreign or other governmental body ("GOVERNMENTAL BODY") with respect to the
transactions contemplated by this Agreement, and to submit promptly any
additional information requested by any such Governmental Body. Without limiting
the generality of the foregoing, the Company and Purchaser shall, promptly after
the date of this Agreement, prepare and file the notifications required under
the HSR Act in connection with the transactions contemplated by this Agreement.
The Company and Purchaser shall respond as promptly as practicable to (i) any
inquiries or requests received from the Federal Trade Commission or the
Department of Justice for additional information or documentation and (ii) any
inquiries or requests received from any state attorney general or other
Governmental Body in connection with antitrust or related matters. Each of the
Company and Purchaser shall (a) give the other party prompt notice of the
commencement of any action, suit, litigation, arbitration, preceding or
investigation ("LEGAL PROCEEDING") by or before any Governmental Body with
respect to the transactions contemplated by this Agreement, (b) keep the other
party informed as to the status of any such Legal Proceeding, and (c) promptly
inform the other party of any communication to or from the Federal Trade
Commission, the Department of Justice or any other Governmental Body regarding
the transactions contemplated by this Agreement.

                  7.4 AMENDMENT OF CERTIFICATE OF INCORPORATION OR BYLAWS. The
Company shall take all steps reasonably necessary to amend the Certificate of
Incorporation and Bylaws to implement the rights and obligations of the parties
contained herein to the extent necessary or appropriate under Delaware law.

                  7.5 AUTHORIZATION AND ISSUANCE OF SERIES A PREFERRED STOCK.
The Company agrees that from the date hereof it shall not increase the
authorized number of shares of Series A Preferred Stock set forth in the
Certificate of Designation and shall not issue any shares of Series A Preferred

Agreement or the conversion or exercise of any of the securities to be acquired
by Purchaser pursuant to this Agreement), (b) any acquisition of any assets
(other than acquisitions in the ordinary course of business) of the Company, any
of its subsidiaries or other Affiliates or any division of the Company, or any
successor to the Company, (c) any tender or exchange offer, merger or business
combination involving the Company or any of its subsidiaries or other
Affiliates, or involving any securities of the Company or any securities of any
subsidiary or other Affiliate of the Company, (d) any recapitalization,
restructuring, liquidation, dissolution or other extraordinary transaction with
respect to the Company or any of its subsidiaries or other Affiliates, or
involving any securities of the Company or any securities of any subsidiary or
other Affiliate of the Company, or (e) any "solicitation" of "proxies" (as such
terms are used in the proxy rules of the SEC) or consents to vote any voting
securities of the Company; (ii) form, join or in any way participate in a
"group" (as defined under the Exchange Act and the rules promulgated thereunder)
with respect to the Company or the beneficial ownership of any securities of the
Company; (iii) otherwise act, alone or in concert with others, to seek to
control or influence the management, board of directors or policies of the
Company; (iv) take any action that would be expected to require the Company to
make a public announcement regarding any of the matters set forth in clause (i)
of this sentence; (v) agree or offer to take or knowingly encourage or propose
(publicly or otherwise) the taking of, any action referred to in clauses (i),
(ii), (iii) or (iv) of this sentence; or (vi) enter into any discussions or
arrangements with any third party with respect to any of the foregoing;
PROVIDED, HOWEVER, that notwithstanding the foregoing, Purchaser may acquire
beneficial ownership of up to forty percent (40%) of the Common Stock of the
Company outstanding on a fully diluted basis (the "PERMITTED PERCENTAGE").
Notwithstanding the foregoing, in the event that:

                           (a) any person or entity that is not an Affiliate of
                  Purchaser has commenced a hostile tender or exchange offer
                  (without the support or encouragement of Purchaser or any
                  Affiliate of Purchaser) for at least a majority of the
                  outstanding shares of Common Stock of the Company;

                           (b) any person or entity that is not an Affiliate of
                  Purchaser has publicly announced that it has purchased or
                  intends to purchase (in the open market, by agreement or
                  otherwise) shares of the equity securities of the Company
                  constituting at least a majority of the outstanding voting
                  securities of the Company with respect to the election of
                  directors, and in the case of purchases in the open market,
                  Purchaser has a good faith belief that such purchases have
                  commenced;

                           (c) any person or entity (other than the Company)
                  that is not an Affiliate of Purchaser has publicly announced
                  that it intends to solicit, or has commenced solicitation of,
                  proxies or consents to elect (or remove) a majority of the
                  members of the Board of Directors of the Company;

                           (d) the Board of Directors of the Company formally
                  approves any transaction or definitive agreement with respect
                  to a transaction that would upon consummation constitute a
                  change of control of the Company; or


                                      -18-
<PAGE>

                           (e) the Board of Directors of the Company adopts
                  resolutions approving the disposition of all or substantially
                  all of the assets of the Company (an event described in (a)
                  through (e) of this sentence shall be an "EXCEPTION EVENT");

then the Permitted Percentage shall toll and have no force or effect beginning
immediately upon the occurrence of such Exception Event and ending on the
Standstill Resumption Date (provided such Standstill Resumption Date is prior to
the Standstill Expiration Date). The "STANDSTILL RESUMPTION DATE" shall be (y)
with respect to any Exception Event described in clause (a), (b) or (c) above,
the date the applicable third party publicly announces that it has abandoned
such transaction and (z) with respect to any Exception Event described in clause
(d) or (e) above, the date the Company notifies the Purchaser in writing that
such Exception Event has been terminated or abandoned or is no longer
applicable, which written notice shall be accompanied by evidence reasonably
satisfactory to Purchaser of the termination or abandonment of (A) such
Exception Event or (B) the resolution of the Board of Directors of the Company
which originally approved such Exception Event. On the Standstill Resumption
Date (provided it is prior to the Standstill Expiration Date), the provisions of
this Section 7.7 would immediately apply to Purchaser with full force and
effect, except that the Permitted Percentage would be increased, but in no event
decreased, to equal Purchaser's beneficial ownership interest as of the
Standstill Resumption Date. The Company confirms to Purchaser that, as of the
date of this Agreement, Purchaser is not in possession of any material
non-public information about the Company as a result of the due diligence
materials or other information provided by the Company to Purchaser on or prior
to the date of this Agreement that would prohibit Purchaser from trading in the
Company's securities.

                  7.8 SHAREHOLDER RIGHTS PLAN. The Company shall not adopt a
shareholder rights plan or similar defensive measure unless, in connection with
such adoption, Purchaser is made exempt from such plan up to the Permitted
Percentage (as it may be adjusted from time to time under Section 7.7), whether
or not the provisions of Section 7.7 are in effect or have terminated.

         8.       FEES AND EXPENSES. All costs and expenses incurred in
connection with this Agreement and the consummation of the transactions
contemplated hereby shall be paid by the party incurring such expenses;
PROVIDED, HOWEVER, that the Company shall pay to the Purchaser, the Purchaser's
fees and expenses incurred in connection with the transactions contemplated by
this Agreement not to exceed $1,000,000; and PROVIDED, FURTHER that the Company
shall pay such fees and expenses within two (2) business days of the Closing.

         9.       MISCELLANEOUS.

                  9.1 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENT.
Notwithstanding any investigation made by any party to this Agreement, the
representations and warranties made by the Company and Purchaser in connection
with the Closing shall not survive the Closing (other than the representations
and warranties of the Company set forth in Sections 3.4.1, 3.4.2(iii), 3.5 and
3.6, which shall survive indefinitely), and shall thereafter be of no further
force or effect, except in the case of fraud in connection with this


                                      -19-
<PAGE>

Agreement. All covenants and agreements contained in this Agreement shall
survive the Closing Date in accordance with their terms.

Stock by reason of a stock dividend, split-up, recapitalization, combination,

                  9.4 ASSIGNABILITY AND ENFORCEABILITY. This Agreement shall be
binding on and enforceable by the parties and their respective successors and
permitted assigns. No party may assign any of its rights, benefits or
obligations under this Agreement to any person or entity without the prior
written consent of the other party; PROVIDED, HOWEVER, that Purchaser may assign
its rights, benefits or obligations under this Agreement, without the prior
consent of the Company, to an Affiliate of Purchaser (for purposes of this
Section and Section 7.7, a person or entity shall be deemed to be an Affiliate
of Purchaser or the Company only if the control relationship involves direct or
indirect ownership of at least a majority of the outstanding voting interests of
the applicable entity, it being understood that any entity that is majority
owned (directly or indirectly) by a person or entity that directly or indirectly
owns a majority of the outstanding voting interests of Purchaser shall be an
Affiliate of Purchaser for these purposes). No such assignment shall relieve the
Purchaser of its obligations under this Agreement.

                  9.5 AMENDMENTS AND WAIVERS. No amendment or waiver of any
provision of this Agreement shall be binding on any party unless consented to in
writing by such party. No waiver of any provision of this Agreement shall be
construed as a waiver of any other provision nor shall any waiver constitute a
continuing waiver unless otherwise expressly provided. No provision of this
Agreement shall be deemed waived by a course of conduct including the act of
Closing unless such waiver is in writing signed by all parties and stating
specifically that it was intended to modify this Agreement. Notwithstanding the
foregoing, any term of this Agreement which applies to the rights applicable to
the holders of the Series A Preferred Stock may be amended and the observance of
any term of this Agreement may be waived (either generally or in a particular
instance and either retroactively or prospectively) only with the written
consent of the Company and the holders of more than 50% of the outstanding
shares of Series A Preferred Stock. Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each holder of Series A
Preferred Stock.

                  9.6 ENTIRE AGREEMENT. This Agreement and the other Transaction
Documents, including the Schedules and Exhibits and any agreements or documents
referred to herein or therein or executed contemporaneously herewith or
therewith, constitutes the entire agreement among the parties with respect to
the subject matter hereof and supersedes all prior agreements, understandings,
negotiations and discussions, whether written or oral. There are no conditions,
covenants, agreements, representations, warranties or other provisions, express
or implied, collateral, statutory or otherwise, relating to the subject matter
hereof except as herein provided.

                  9.7 HEADINGS. The headings of the various sections of this
Agreement have been inserted for convenience of reference only and shall not be
deemed to be part of this Agreement.

                  9.8 SEVERABILITY. In case any provision contained in this
Agreement should be invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby.

                  9.9 GOVERNING LAW. This Agreement shall be governed by and

matters which are subject to the Delaware General Corporation Law, which shall
be governed by such law, in each case without regard to the choice of law
provisions thereof.

                  9.10 COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original, but all of which,
when taken together, shall constitute but one instrument, and shall become
effective when one or more counterparts have been signed by each party hereto
and delivered to the other parties.
