                         REPRESENTATIONS AND WARRANTIES

         2.1 REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
makes the following representations and warranties to the Purchasers:

                  (a) ORGANIZATION AND QUALIFICATION. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of California, with the requisite corporate power and
authority to own and use its properties and assets and to carry on its business
as currently conducted. The Company has no subsidiaries other than as set forth
in SCHEDULE 2.1(A) (collectively the "SUBSIDIARIES"). Each of the Subsidiaries
is an entity, duly incorporated or otherwise organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
organization (as applicable), with the full power and authority to own and use
its properties and assets and to carry on its business as currently conducted.
Each of the Company and the Subsidiaries is duly qualified to do business and is
in good standing as a foreign corporation in each jurisdiction in which the
nature of the business conducted or property owned by it makes such
qualification necessary, except where the failure to be so qualified or in good
standing, as the case may be, could not, individually or in the aggregate, (x)
adversely affect the legality, validity or enforceability of the Debentures or
any of this Agreement, the Registration Rights Agreement, the Warrants, the
Security Agreement or the IP Security Agreement, dated May 17, 1999, by and
among the Company and the Purchasers, as amended by the Security Agreements
Amendment (the "SECURITY AGREEMENT"), dated May 17, 1999, by and among the

                                      -2-
<PAGE>

Company and the Purchaser, as amended by the Security Agreements Amendment (the
"IP SECURITY AGREEMENT") (collectively, the "TRANSACTION DOCUMENTS"), (y) have
or result in a material adverse effect on the results of operations, assets,
prospects, or condition (financial or otherwise) of the Company and the
Subsidiaries, taken as a whole, or (z) adversely impair the Company's ability to
perform fully on a timely basis its obligations under any of the Transaction
Documents (any of (x), (y) or (z), a "MATERIAL ADVERSE EFFECT").

                  (b) AUTHORIZATION; ENFORCEMENT. The Company has the requisite
corporate power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations thereunder. The execution and delivery of each of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated thereby have been duly authorized by all necessary action on the
part of the Company and no further action is required by the Company. Each of
the Transaction Documents and the Debentures has been duly executed by the
Company and, when delivered (or filed, as the case may be) in accordance with
the terms hereof, will constitute the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms. Neither
the Company nor any Subsidiary is in violation of any of the provisions of its
respective certificate of incorporation, by-laws or other charter documents.

                  (c) CAPITALIZATION. The number of authorized, issued and
outstanding capital stock of the Company is set forth in SCHEDULE 2.1(C). No
shares of Common Stock are entitled to preemptive or similar rights, nor is any
holder of the Common Stock entitled to preemptive or similar rights arising out
of any agreement or understanding with the Company by virtue of any of the
Transaction Documents. Except as a result of the purchase and sale of the
Debentures and the Warrants and except as disclosed in SCHEDULE 2.1(C), there
are no outstanding options, warrants, script rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities, rights or
obligations convertible into or exchangeable for, or giving any Person (as
defined below) any right to subscribe for or acquire, any shares of Common
Stock, or contracts, commitments, understandings, or arrangements by which the
Company or any Subsidiary is or may become bound to issue additional shares of
Common Stock, or securities or rights convertible or exchangeable into shares of
Common Stock. To the knowledge of the Company, except as specifically disclosed
in the SEC Documents (as defined below) or SCHEDULE 2.1(C), no Person or group
of related Persons beneficially owns (as determined pursuant to Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT")), or has the right to acquire by agreement with or by obligation binding
upon the Company, in excess of 5% of the Common Stock. A "PERSON" means an
individual or corporation, partnership, trust, incorporated or unincorporated
association, joint venture, limited liability company, joint stock company,
government (or an agency or subdivision thereof) or other entity of any kind.

                  (d) ISSUANCE OF THE DEBENTURES AND THE WARRANTS. The
Debentures and the Warrants are duly authorized and, when issued and paid for in
accordance with the terms hereof, will be duly and validly issued, fully paid
and nonassessable, free and clear of all liens, encumbrances and rights of first
refusal of any kind (collectively, "LIENS"). The Company has on the date hereof

                                      -3-
<PAGE>

and will, at all times while the Debentures and the Warrants are outstanding,
maintain an adequate reserve of duly authorized shares of Common Stock, reserved
for issuance to the holders of the Debentures and the Warrants, to enable it to
perform its conversion, exercise and other obligations under this Agreement, the
Debentures and the Warrants. Such number of reserved and available shares of
Common Stock is not less than the sum of (i) 200% of the number of shares of
Common Stock which would be issuable upon conversion in full of the Debentures,
assuming such conversion occurred on the Original Issue Date for the Debentures,
the Filing Date or the Effectiveness Date (each as defined in the Registration
Rights Agreement), whichever yields the lowest Conversion Price, (ii) the number
of shares of Common Stock issuable upon exercise of the Warrants, and (iii) the
number of shares Common Stock which would be issuable upon payment of interest
on the Debentures, assuming the Debentures are outstanding for three years and
all interest is paid in shares of Common Stock (such number of shares of Common
Stock as contemplated in clauses (i)-(iii), the "INITIAL MINIMUM"). All such
authorized shares of Common Stock shall be duly reserved for issuance to the
holders of the Debentures and the Warrants. The shares of Common Stock issuable
upon conversion of the Debentures, as payment of interest thereon and upon
exercise of the Warrants are collectively referred to herein as the "UNDERLYING
SHARES." The Debentures, the Warrants and the Underlying Shares are collectively
referred to herein as, the "SECURITIES." When issued in accordance with the
Debentures and the Warrants, the Underlying Shares will be duly authorized,
validly issued, fully paid and nonassessable, free and clear of all Liens.

                  (e) NO CONFLICTS. The execution, delivery and performance of
the Transaction Documents by the Company and the consummation by the Company of
the transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of its articles of incorporation, bylaws or other charter
documents (each as amended through the date hereof), or (ii) subject to
obtaining the Required Approvals (as defined below), conflict with, or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation (with or without notice, lapse of time
or both) of, any agreement, credit facility, indenture or instrument (evidencing
a Company debt or otherwise) to which the Company or any Subsidiary is a party
or by which any property or asset of the Company or any Subsidiary is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental
authority to which the Company is subject (including Federal and state
securities laws and regulations), or by which any property or asset of the
Company is bound or affected, except in the case of each of clauses (ii) and
(iii), as could not, individually or in the aggregate, have or result in a
Material Adverse Effect. The business of the Company is not being conducted in
violation of any law, ordinance or regulation of any governmental authority,
except for violations which, individually or in the aggregate, could not have or
result in a Material Adverse Effect. The sale and issuance of the Securities
hereunder shall not cause any Purchaser or Purchasers to be an "Acquiring
Person" under the Rights Plan (as defined in Section 3.17).

                  (f) FILINGS, CONSENTS AND APPROVALS. Neither the Company nor
any Subsidiary is required to obtain any consent, waiver, authorization or order
of, give any notice to, or make any filing or registration with, any court or
other Federal, state, local or other governmental authority or other Person in
connection with the execution, delivery and performance by the Company of the
Transaction Documents, other than (i) the filings required pursuant to Section
3.11, (ii) the filing with the Securities and Exchange Commission (the

                                      -4-
<PAGE>

"COMMISSION") of a registration statement meeting the requirements set forth in
the Registration Rights Agreement and covering the resale of the Underlying
Shares by the Purchasers (the "UNDERLYING SHARES REGISTRATION STATEMENT"), (iii)
the application(s) to the Nasdaq National Market ("NASDAQ") for the listing of
the Underlying Shares for trading on the NASDAQ (and with any other national
securities exchange or market on which the Common Stock is then listed), (iv)
applicable Blue Sky filings and (v) in all other cases where the failure to
obtain such consent, waiver, authorization or order, or to give such notice or
make such filing or registration could not have or result in, individually or in
the aggregate, a Material Adverse Effect (collectively, the "REQUIRED
APPROVALS").

                  (g) LITIGATION; PROCEEDINGS. Except as specifically disclosed
in SCHEDULE 2.1(G), there is no action, suit, notice of violation, proceeding or
investigation pending or, to the knowledge of the Company, threatened against or
affecting the Company or any of its Subsidiaries or any of their respective
properties before or by any court, governmental or administrative agency or
regulatory authority (Federal, state, county, local or foreign) which (i)
adversely affects or challenges the legality, validity or enforceability of any
of the Transaction Documents or the Securities or (ii) could, individually or in
the aggregate, have or result in a Material Adverse Effect.

                  (h) NO DEFAULT OR VIOLATION. Neither the Company nor any
Subsidiary (i) is in default under or in violation of (and no event has occurred
which has not been waived which, with notice or lapse of time or both, would
result in a default by the Company or any Subsidiary under), nor has the Company
or any Subsidiary received notice of a claim that it is in default under or that
it is in violation of, any indenture, loan or credit agreement or any other
agreement or instrument to which it is a party or by which it or any of its
properties is bound, (ii) is in violation of any order of any court, arbitrator
or governmental body, or (iii) is in violation of any statute, rule or
regulation of any governmental authority, except as could not individually or in
the aggregate, have or result in a Material Adverse Effect. The security
interests granted to the Purchasers pursuant to the Security Agreement and IP
Security Agreement will convey and grant to the Purchasers a first priority
security interest in all of the Collateral (as such terms is defined in such
agreements).

                  (i) PRIVATE OFFERING. Assuming the accuracy of the
representations and warranties of the Purchasers set forth in Sections
2.2(b)-(g), the offer, issuance and sale of the Securities to the Purchasers as
contemplated hereby are exempt from the registration requirements of the
Securities Act of 1933, as amended (the "SECURITIES ACT"). Neither the Company

offering, issuance or sale of the Securities to the registration requirements of
the Securities Act.

in SCHEDULE 2.1 (J) attached hereto, the Company has filed all reports required
to be filed by it under the Exchange Act, including pursuant to Section 13(a) or

together with the Schedules to this Agreement, the "DISCLOSURE MATERIALS") on a

                                      -5-

timely basis or has received a valid extension of such time of filing and has
filed any such SEC Documents prior to the expiration of any such extension. As
of their respective dates, the SEC Documents complied in all material respects
with the requirements of the Securities Act and the Exchange Act and the rules
and regulations of the Commission promulgated thereunder, and none of the SEC
Documents, when filed, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. All material agreements to which the Company is
a party or to which the property or assets of the Company are subject have been
filed as exhibits to the SEC Documents as required. The financial statements of
the Company included in the SEC Documents comply in all material respects with
applicable accounting requirements and the rules and regulations of the

financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
("GAAP"), except as may be otherwise specified in such financial statements or
the notes thereto, and fairly present in all material respects the financial
position of the Company and its consolidated subsidiaries as of and for the
dates thereof and the results of operations and cash flows for the periods then
ended, subject, in the case of unaudited statements, to normal, immaterial,

financial statements pursuant to GAAP or required to be disclosed in filings
made with the Commission, (c) the Company has not altered its method of
accounting or the identity of its auditors and (d) the Company has not declared

redeemed (or made any agreements to purchase or redeem) any shares of its
capital stock.

                  (k) INVESTMENT COMPANY. The Company is not, and is not an
Affiliate (as defined in Rule 405 under the Securities Act) of, an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.

                  (l) CERTAIN FEES. Except for certain fees payable by the
Company to Wharton Capital Partners, Ltd., and its Affiliates, no fees or
commissions will be payable by the Company to any broker, financial advisor or
consultant, finder, placement agent, investment banker, or bank with respect to
the transactions contemplated by this Agreement. The Purchasers shall have no
obligation with respect to any fees or with respect to any claims made by or on
behalf of other Persons for fees of a type contemplated in this Section that may
be due in connection with the transactions contemplated by this Agreement. The
Company shall indemnify and hold harmless the Purchasers, their employees,
officers, directors, agents, and partners, and their respective Affiliates, from
and against all claims, losses, damages, costs (including the costs of
preparation and attorney's fees) and expenses suffered in respect of any such
claimed or existing fees, as such fees and expenses are incurred.

<PAGE>

                  (m) SOLICITATION MATERIALS. Neither the Company nor any Person
acting on the Company's behalf has solicited any offer to buy or sell the
Securities by means of any form of general solicitation or advertising.

                  (n) FORM S-3 ELIGIBILITY. The Company is eligible to register
securities for resale with the Commission under Form S-3 promulgated under the
Securities Act.

                  (o) EXCLUSIVITY. The Company shall not issue and sell the
Debentures to any Person other than the Purchasers other than with the specific
prior written consent of the Purchasers.

                  (p) SENIORITY. No indebtedness of the Company is senior to the
Debentures in right of payment, whether with respect to interest or upon
liquidation, dissolution or otherwise.

                  (q) LISTING AND MAINTENANCE REQUIREMENTS COMPLIANCE. Except as
specified in SCHEDULE 2.1 (Q) hereto, the Company has not, in the two years
preceding the date hereof, received notice (written or oral) from the NASDAQ or
any other stock exchange, market or trading facility on which the Common Stock
is or has been listed (or on which it has been quoted) to the effect that the
Company is not in compliance with the listing or maintenance requirements of
such exchange or market. The Company is, and has no reason to believe that it
will not in the foreseeable future continue to be, in compliance with all such
maintenance requirements.

                  (r) PATENTS AND TRADEMARKS. The Company has, or has rights to
use, all patents, patent applications, trademarks, trademark applications,
service marks, trade names, copyrights, licenses and rights which are necessary
or material for use in connection with its business, and which the failure to so
have would have a Material Adverse Effect (collectively, the "INTELLECTUAL
PROPERTY RIGHTS"). The patents and trademark specified in the IP Security
Agreement are the only patent or trademark intellectual property rights (or
applications therefor) held by the Company and the Subsidiaries for which
applications for patents and trademarks have been made or granted in the United
States (excluding, for such purposes, patents and trademarks held by Ophthalmic
Imaging Systems, Inc.). To the best knowledge of the Company all such
Intellectual Property Rights are enforceable and there is no existing
infringement by another Person of any of the Intellectual Property Rights.

                  (s) REGISTRATION RIGHTS; RIGHTS OF PARTICIPATION. Except as
set forth on SCHEDULE 6(B) to the Registration Rights Agreement, the Company has
not granted or agreed to grant to any Person any rights (including "piggy-back"
registration rights) to have any securities of the Company registered with the
Commission or any other governmental authority which has not been satisfied. No
Person, has any right of first refusal, preemptive right, right of
participation, or any similar right to participate in the transactions
contemplated by the Transaction Documents.

                  (t) REGULATORY PERMITS. The Company and its Subsidiaries
possess all certificates, authorizations and permits issued by the appropriate
Federal, state or foreign regulatory authorities necessary to conduct their
respective businesses as described in the SEC Documents, except where the
failure to possess such permits could not, individually or in the aggregate,
have or result in a Material Adverse Effect ("MATERIAL PERMITS"), and neither
the Company nor any such Subsidiary has received any notice of proceedings
relating to the revocation or modification of any Material Permit.

                                      -7-
<PAGE>

                  (u) TITLE. The Company and the Subsidiaries have good and
marketable title in fee simple to all real property and personal property owned
by them which is material to the business of the Company and its Subsidiaries,
in each case free and clear of all Liens, except for Liens granted to the
Purchasers pursuant to the Security Agreement and IP Security Agreement and for
other Liens as do not materially affect the value of such property and do not
interfere with the use made and proposed to be made of such property by the
Company and its Subsidiaries. Any real property and facilities held under lease
by the Company and its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

                  (v) DISCLOSURE. The Company confirms that it has not provided
any of the Purchasers or its agents or counsel with any information that
constitutes or might constitute material non-public information. The Company
understands and confirms that the Purchasers shall be relying on the foregoing
representations in effecting transactions in securities of the Company. All
disclosure provided to the Purchasers regarding the Company, its business and
the transactions contemplated hereby, including the Schedules to this Agreement,
furnished by or on behalf of the Company are true and correct and do not contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading.

                  (w) OPHTHALMIC IMAGING SYSTEMS, INC. The Company owns free and
clear of all Liens 2,131,758 shares of the common stock, no par value, of
Ophthalmic Imaging Systems, Inc., a California corporation, and 150 shares of
Series B Preferred Stock, which together represent 51% of the total issued and
outstanding shares of voting stock of such entity (the "OPHTHALMIC SHARES").

                  (x) The Company has not issued any of the shares of Common
Stock permitted to be issued or paid any other monies permitted to be paid under
Section 3(a)(xiii) of the Debentures.

         2.2 REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each Purchaser
hereby represents and warrants to the Company as follows:

                  (a) ORGANIZATION; AUTHORITY. Such Purchaser is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation with the requisite corporate power and
authority, to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations thereunder. The
purchase by such Purchaser of the Securities hereunder has been duly authorized
by all necessary action on the part of such Purchaser. Each of this Agreement,
the Registration Rights Agreement, the Security Agreement Amendment and the IP
Security Amendment has been duly executed and delivered by such Purchaser and
constitutes the valid and legally binding obligation of such Purchaser,
enforceable against it in accordance with its terms.

<PAGE>

                  (b) INVESTMENT INTENT. Such Purchaser is acquiring the
Securities for its own account for investment purposes only and not with a view
to or for distributing or reselling such Securities or any part thereof or
interest therein, without prejudice, however, to such Purchaser's right, subject
to the provisions of this Agreement and the Registration Rights Agreement, at
all times to sell or otherwise dispose of all or any part of such Securities
pursuant to an effective registration statement under the Securities Act and in
compliance with applicable state securities laws or under an exemption from such
registration. Nothing contained herein shall be deemed a representation or
warranty by such Purchaser to hold Securities for any amount of time.

                  (c) PURCHASER STATUS. At the time such Purchaser was offered
the Debentures and the Warrant, it was, and at the date hereof it is, and at
each exercise date under the Warrant, it will be, an "accredited investor" as
defined in Rule 501(a) under the Securities Act.

                  (d) EXPERIENCE OF THE PURCHASER. Such Purchaser, either alone
or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

                  (e) ABILITY OF THE PURCHASER TO BEAR RISK OF INVESTMENT. Such
Purchaser is able to bear the economic risk of an investment in the Securities
and, at the present time, is able to afford a complete loss of such investment.

                  (f) ACCESS TO INFORMATION. Such Purchaser acknowledges that it
has reviewed the Disclosure Materials and has been afforded (i) the opportunity
to ask such questions as it has deemed necessary of, and to receive answers
from, representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and risks of investing in the
Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, properties, management and
prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its representatives or counsel shall modify, amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the Disclosure Materials and the Company's representations and warranties
contained in the Transaction Documents.

                  (g) GENERAL SOLICITATION. Such Purchaser is not purchasing the
Securities as a result of or subsequent to any advertisement, article, notice or
other communication regarding the Securities published in any newspaper,

any seminar or any other general solicitation or general advertisement.

                  (h) RELIANCE. Such Purchaser understands and acknowledges that
(i) the Securities are being offered and sold to it without registration under
the Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption,
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing representations and such Purchaser hereby consents to such
reliance.

                  The Company acknowledges and agrees that each of the
Purchasers makes no representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in this
Section 2.2.

                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

         3.1 TRANSFER RESTRICTIONS. (a) Securities may only be disposed of
pursuant to an effective registration statement under the Securities Act, to the
Company or pursuant to an available exemption from or in a transaction not
subject to the registration requirements of the Securities Act. In connection
with any transfer of Securities other than pursuant to an effective registration
statement or to the Company, except as otherwise set forth herein, the Company
may require the transferor thereof to provide to the Company an opinion of
counsel selected by the transferor, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred Securities under the
Securities Act. Notwithstanding the foregoing, the Company, without requiring a
legal opinion as described in the immediately preceding sentence, hereby
consents to and agrees to register on the books of the Company and with any
transfer agent for the securities of the Company any transfer of Securities by a
Purchaser to an Affiliate of such Purchaser or to one or more funds or managed
accounts under common management with such Purchaser, and any transfer among any
such Affiliates or one or more funds or managed accounts, provided that the
transferee certifies to the Company that it is an "accredited investor" as
defined in Rule 501(a) under the Securities Act and that it is acquiring the
Securities solely for investment purposes (subject to the qualifications
hereof). Any such transferee shall agree in writing to be bound by the terms of
this Agreement and shall have the rights of a Purchaser under this Agreement and
the Registration Rights Agreement.

                  (b) The Purchasers agree to the imprinting, so long as is
required by this Section 3.1(b), of the following legend on the Securities:

                  NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE
         SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH
         THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF
         ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
         AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
         REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
         APPLICABLE STATE SECURITIES LAWS.

                                      -10-
<PAGE>

                  Underlying Shares shall not contain the legend set forth above
nor any other legend if the conversion of Debentures, the payment of interest
thereon, and exercise of the Warrants or other issuances of Underlying Shares as
contemplated hereby, by the Debentures or the Warrants occurs at any time while
an Underlying Shares Registration Statement is effective under the Securities
Act or, in the event there is not an effective Underlying Shares Registration
Statement, at such time, in the opinion of counsel to the Company, such legend
is not required under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the
Commission). The Company shall cause its counsel to issue the legal opinion
included in the Transfer Agent Instructions to the Company's transfer agent on
the day that the Underlying Shares Registration Statement is declared effective
by the Commission. The Company agrees that, in the event any Underlying Shares
are issued with a legend in accordance with this Section 3.1(b), it will, within
three (3) Trading Days after request therefor by a Purchaser, provide such
Purchaser with a certificate or certificates representing such Underlying
Shares, free from such legend at such time as such legend would not have been
required under this Section 3.1(b) had such issuance occurred on the date of
such request. The Company may not make any notation on its records or give
instructions to any transfer agent of the Company which enlarge the restrictions
of transfer set forth in this Section. However, the Company may provide
appropriate instructions to any transfer agent of the Company to enforce the
provisions of this Section 3.1(b) when the Underlying Shares Registration
Statement is not effective.

         3.2 ACKNOWLEDGMENT OF DILUTION. The Company acknowledges that the
issuance of the Underlying Shares upon (i) conversion of the Debentures and
payment of interest thereon in accordance with the terms of the Debentures, and
(ii) exercise of the Warrants in accordance with their terms, will result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Underlying Shares upon (x) conversion of the
Debentures and payment of interest thereon in accordance with the terms of the
Debentures, and (y) exercise of the Warrants in accordance with their terms, is
unconditional and absolute, subject to the limitations set forth herein in the
Debentures or pursuant to the Warrants, regardless of the effect of any such
dilution.

         3.3 FURNISHING OF INFORMATION. As long as the Purchasers own
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or 15(d) of the Exchange Act. As long as the Purchasers own Securities, if
the Company is not required to file reports pursuant to such sections, it will
prepare and furnish to the Purchasers and make publicly available in accordance
with Rule 144(c) promulgated under the Securities Act such information as is
required for the Purchasers to sell the Securities under Rule 144 promulgated
under the Securities Act. The Company further covenants that it will take such
further action as any holder of Securities may reasonably request, all to the
extent required from time to time to enable such Person to sell Underlying
Shares without registration under the Securities Act within the limitation of
the exemptions provided by Rule 144 promulgated under the Securities Act,
including the legal opinion referenced above in this Section. Upon the request
of any such Person, the Company shall deliver to such Person a written
certification of a duly authorized officer as to whether it has complied with
such requirements.

                                      -11-
<PAGE>

         3.4 INTEGRATION. The Company shall not, and shall use its best efforts
to ensure that, no Affiliate of the Company shall, sell, offer for sale or
solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchasers.

         3.5 INCREASE IN AUTHORIZED SHARES. If on any date the Company would be,
if a notice of conversion or exercise (as the case may be) were to be delivered
on such date, precluded from (a) issuing 200% of the number of Underlying Shares
as would then be issuable upon a conversion in full of the Debentures and as
payment of any accrued and unpaid interest in respect thereof in shares of
Common Stock, or (b) issuing the number of Underlying Shares upon exercise in
full of the Warrants (the "CURRENT REQUIRED MINIMUM"), in either case, due to
the unavailability of a sufficient number of authorized but unissued or reserved
shares of Common Stock, then the Board of Directors of the Company shall
promptly (and in any case, within 30 Business Days from such date) prepare and
mail to the stockholders of the Company proxy materials requesting authorization
to amend the Company's Articles of Incorporation to increase the number of
shares of Common Stock which the Company is authorized to issue to at least such
number of shares as reasonably requested by the Purchasers in order to provide
for such number of authorized and unissued shares of Common Stock to enable the
Company to comply with its issuance, conversion exercise and reservation of
shares obligations as set forth in this Agreement, the Debentures and the
Warrants (the sum of (x) the number of shares of Common Stock then outstanding
plus all shares of Common Stock issuable upon exercise of all outstanding
options, warrants and convertible instruments, and (y) the Current Required
Minimum, shall be a reasonable number). In connection therewith, the Board of
Directors shall (a) adopt proper resolutions authorizing such increase, (b)
recommend to and otherwise use its best efforts to promptly and duly obtain
stockholder approval to carry out such resolutions (and hold a special meeting
of the stockholders no later than the 60th day after delivery of the proxy
materials relating to such meeting) and (c) within five (5) Business Days of
obtaining such stockholder authorization, file an appropriate amendment to the
Company's Articles of Incorporation to evidence such increase.

         3.6 RESERVATION AND LISTING OF UNDERLYING SHARES. (a) The Company shall
(i) in the time and manner required by NASDAQ and such other exchange, market or
quotation system on which the Common Stock is traded, prepare and file with the
NASDAQ (and such other national securities exchange or market or trading or
quotation facility) an additional shares listing application covering a number
of shares of Common Stock which is not less than the Initial Minimum, (ii) take
all steps necessary to cause such shares of Common Stock to be approved for
listing in the NASDAQ (as well as on any such other national securities exchange
or market or trading or quotation facility on which the Common Stock is then
listed) as soon as possible thereafter, and (iii) provide to the Purchasers
evidence of such listing, and the Company shall maintain the listing of its

                                      -12-
<PAGE>

Common Stock thereon. If the number of Underlying Shares issuable upon
conversion in full of the then outstanding Debentures, as payment of interest
thereon, and upon exercise of the then unexercised portion of the Warrants
exceeds 85% of the number of Underlying Shares previously listed on account
thereof with NASDAQ (and any such other required exchanges), then the Company
shall take the necessary actions to immediately list a number of Underlying
Shares as equals no less than the then Current Required Minimum.

                  (b) The Company shall maintain a reserve of shares of Common
Stock for issuance upon conversion of the Debentures and for payment of interest
thereupon in shares of Common Stock and upon exercise in full of the Warrants in
accordance with this Agreement, the Debentures and the Warrants, respectively,
in such amount as may be required to fulfill its obligations in full under the
Transaction Documents, which reserve shall equal no less than the then Current
Required Minimum.

         3.7 CONVERSION AND EXERCISE PROCEDURES. The Conversion Notice (as
defined in EXHIBIT A) and Form of Election to Purchase under the Warrants set
forth the totality of the procedures with respect to the conversion of the
Debentures and exercise of the Warrants, including the form of legal opinion, if
necessary, that shall be rendered to the Company's transfer agent and such other
information and instructions as may be reasonably necessary to enable the
Purchasers to convert their Debentures and exercise their Warrants as
contemplated in the Debentures and the Warrants (as applicable).

         3.8 NOTICE OF BREACHES. Each of the Company and the Purchasers shall
give prompt written notice to the other of any breach by it of any
representation, warranty or other agreement contained in any Transaction
Document, as well as any events or occurrences arising after the date hereof
which would reasonably be likely to cause any representation or warranty or
other agreement of such party, as the case may be, contained therein to be
incorrect or breached as of the Closing Date. However, no disclosure by either
party pursuant to this Section shall be deemed to cure any breach of any
representation, warranty or other agreement contained in any Transaction
Document.

         3.9 CONVERSION AND EXERCISE OBLIGATIONS OF THE COMPANY. The Company
shall honor conversions of the Debentures and exercises of the Warrants and
shall deliver Underlying Shares in accordance with the respective terms,
conditions and time periods set forth in the Debentures and the Warrants.

         3.10 RIGHT OF FIRST REFUSAL; SUBSEQUENT REGISTRATIONS. (a) The Company
shall not, directly or indirectly, without the prior written consent of the
Purchasers, offer, sell, grant any option to purchase, or otherwise dispose of
(or announce any offer, sale, grant or any option to purchase or other
disposition) any of its or its Affiliates' equity or equity-equivalent
securities (including the issuance of any debt or other instrument is at any
time over life thereof convertible into or exchangeable for Common Stock or any
other transaction intended to be exempt or not subject to registration under the
Securities Act (a "SUBSEQUENT PLACEMENT") for a period of 180 days after the

                                      -13-
<PAGE>

later to occur of the Effectiveness Date (as defined in the Registration Rights
Agreement) and the date that the Commission first declares effective an
Underlying Shares Registration Statement, except (i) the granting of options or
warrants to employees, consultants, officers and directors, and the issuance of
shares upon exercise of options granted, under any stock option plan heretofore
or hereinafter duly adopted by the Company, (ii) shares of Common Stock issuable
upon exercise of any currently outstanding warrants (including the Class B
Warrants (as defined herein)) and upon conversion of any currently outstanding
convertible securities of the Company, in each case only if such security is
disclosed in SCHEDULE 2.1(C), (iii) shares of Common Stock or Common Stock
Equivalents (as defined in the Debentures) permitted to be issued without giving
rise to an Event of Default under Sections 3(a)(xii) or 3(a)(xiii)(a) of the
Debentures, and (iv) shares of Common Stock issuable upon conversion of
Debentures, as payment of interest thereon and upon exercise of the Warrants in
accordance with the Debentures or the Warrants, respectively, unless (A) the
Company delivers to the Purchasers a written notice (the "SUBSEQUENT PLACEMENT
NOTICE") of its intention effect such Subsequent Placement, which Subsequent
Placement Notice shall describe in reasonable detail the proposed terms of such
Subsequent Placement, the amount of proceeds intended to be raised thereunder,
the Person with whom such Subsequent Placement shall be effected, and attached
to which shall be a term sheet or similar document relating thereto and (B) the
Purchasers shall not have notified the Company by 5:00 p.m. (New York City time)
on the tenth (10th) Trading Day after their receipt of the Subsequent Placement
Notice of their willingness to cause the Purchasers to provide (or to cause its
sole designee to provide), subject to completion of mutually acceptable
documentation, financing to the Company on the same terms set forth in the
Subsequent Placement Notice. If the Purchasers shall fail to notify the Company
of their intention to enter into such negotiations within such time period, the
Company may effect the Subsequent Placement substantially upon the terms and to
the Persons (or Affiliates of such Persons) set forth in the Subsequent
Placement Notice; PROVIDED, that the Company shall provide the Purchasers with a
second Subsequent Placement Notice, and the Purchasers shall again have the
right of first refusal set forth above in this paragraph (a), if the Subsequent
Placement subject to the initial Subsequent Placement Notice shall not have been
consummated for any reason on the terms set forth in such Subsequent Placement
Notice within thirty (30) Trading Days after the date of the initial Subsequent
Placement Notice with the Person (or an Affiliate of such Person) identified in
the Subsequent Placement Notice. If the Purchasers shall indicate a willingness
to provide financing in excess of the amount set forth in the Subsequent
Placement Notice, then each Purchaser shall be entitled to provide financing
pursuant to such Subsequent Placement Notice up to an amount equal to such
Purchaser's pro rata portion of the aggregate principal amount of Debentures
purchased by the Purchasers under this Agreement, but the Company shall not be
required to accept financing from the Purchasers in an amount in excess of the
amount set forth in the Subsequent Placement Notice.

                  (b) Except for (x) Underlying Shares, (y) other "Registrable
Securities" (as such term is defined in the Registration Rights Agreement) to be
registered, and securities of the Company permitted pursuant to Schedule 6(b) of
the Registration's Rights Agreement to be registered, in the Underlying Shares
Registration Statement in accordance with the Registration Rights Agreement, and
(z) Common Stock permitted to be issued pursuant to paragraph (a)(i), (ii) and
(iv) of Section 3.10(a), the Company shall not, for a period of not less than 90
Trading Days after the date that the Underlying Shares Registration Statement is
declared effective by the Commission, without the prior written consent of the
Purchasers (i) issue or sell any of its or any of its Affiliates' equity or
equity-equivalent securities pursuant to Regulation S promulgated under the
Securities Act, or (ii) register for resale any securities of the Company. Any
days that a Purchaser is not permitted to sell Underlying Shares under the
Underlying Shares Registration Statement shall be added to such 90 Trading Day
period for the purposes of (i) and (ii) above.

consult with each other in issuing any press releases or otherwise making public
statements or filings and other communications with the Commission or any
regulatory agency or stock market or trading facility with respect to the
transactions contemplated hereby and neither party shall issue any such press
release or otherwise make any such public statement, filings or other
communications without the prior written consent of the other, which consent
shall not be unreasonably withheld or delayed, except that no prior consent
shall be required if such disclosure is required by law, in which such case the
disclosing party shall provide the other party with prior notice of such public
statement, filing or other communication. Notwithstanding the foregoing, the
Company shall not publicly disclose the names of the Purchasers, or include the
names of the Purchasers in any filing with the Commission, or any regulatory
agency, trading facility or stock market without the prior written consent of
the Purchasers, except to the extent such disclosure (but not any disclosure as
to the controlling Persons thereof) is required by law, in which case the
Company shall provide the Purchasers with prior notice of such disclosure.

         3.12 TRANSFER OF INTELLECTUAL PROPERTY RIGHTS. Except in connection
with the sale of all or substantially all of the assets of the Company or
licensing arrangements in the ordinary course of the Company's business, the
Company shall not transfer, sell or otherwise dispose of any Intellectual

renewable and it would otherwise lapse if not renewed), without the prior
written consent of the Purchasers.

         3.13 USE OF PROCEEDS. The Company shall use the net proceeds from the
sales of the Securities hereunder for general working capital purposes only.

         3.14 REIMBURSEMENT. If any Purchaser, other than by reason of its gross
negligence or willful misconduct, becomes involved in any capacity in any
action, proceeding or investigation brought by or against any Person, including
stockholders of the Company, in connection with or as a result of the
consummation of the transactions contemplated by Transaction Documents, the
Company will reimburse such Purchaser for its reasonable legal and other
expenses (including the cost of any investigation and preparation) incurred in
connection therewith, as such expenses are incurred. In addition, other than

                                      -15-
<PAGE>

with respect to any matter in which a Purchaser is a named party, the Company
will pay such Purchaser the charges, as reasonably determined by such Purchaser,
for the time of any officers or employees of such Purchaser devoted to appearing
and preparing to appear as witnesses, assisting in preparation for hearings,
trials or pretrial matters, or otherwise with respect to inquiries, hearings,
trials, and other proceedings relating to the subject matter of this Agreement.
The reimbursement obligations of the Company under this paragraph shall be in
addition to any liability which the Company may otherwise have, shall extend
upon the same terms and conditions to any Affiliates of the Purchasers who are
actually named in such action, proceeding or investigation, and partners,
directors, agents, employees and controlling persons (if any), as the case may
be, of the Purchasers and any such Affiliate, and shall be binding upon and
inure to the benefit of any successors, assigns, heirs and personal
representatives of the Company, the Purchasers and any such Affiliate and any
such Person. The Company also agrees that neither the Purchasers nor any such
Affiliates, partners, directors, agents, employees or controlling persons shall
have any liability to the Company or any Person asserting claims on behalf of or
in right of the Company in connection with or as a result of the consummation of
the Transaction Documents except to the extent that any losses, claims, damages,
liabilities or expenses incurred by the Company result from the gross negligence
or willful misconduct of the applicable Purchaser or entity in connection with
the transactions contemplated by this Agreement.

         3.15 CERTAIN TRADING RESTRICTIONS. The Purchasers will not enter into
any Short Sales (as hereinafter defined) at a price below the Initial Conversion
Price (as defined in the Debentures), PROVIDED, that the limitations set forth
in this Section shall cease to be in effect on the earlier of (x) date that an
Underlying Shares Registration Statement is first declared effective by the
Commission and (y) the Effectiveness Date. For purposes of this Section, a
"Short Sale" by a Purchaser shall mean a sale of Common Stock by such Purchaser
that is marked as a short sale and that is made at a time when there is no
equivalent offsetting long position in Common Stock held by such Purchaser. For
purposes of determining whether there is an equivalent offsetting long position
in Common Stock held by a Purchaser, Underlying Shares that have not yet been
issued but for which the Company has received a Conversion Notice (with respect
to Debentures) or Form of Election to Purchase (with respect to Warrants), as
the case may be, shall be deemed held long by a Purchaser.

         3.16 CERTAIN FUTURE ACTIONS. Subject to compliance with the Transaction
Documents relating thereto, the Company is expressly permitted to (i) lower the
exercise price of its Class B Warrants, entitling the holders thereof to
purchase an aggregate of 7,592,460 shares of Common Stock (the "CLASS B
WARRANTS") and (ii) issue up to an aggregate of 2,250,000 shares of Common Stock
in satisfaction of the litigation described in SCHEDULE 2.1(G) hereto less the
number of shares of Common Stock, if any, which have been issued in respect of
such litigation from May 17, 1999 to the Closing Date.

         3.17 RIGHTS PLAN. The Company may not claim or enforce any claims that
any Purchaser is (or that the Purchasers taken collectively are) an "Acquiring
Person" under the Company's Shareholders Rights Agreement, dated as of March
1998 (or any amendment thereto) (the "RIGHTS PLAN"), by virtue of its purchase
or beneficial ownership of Securities.

         3.18 CONTINUED OWNERSHIP OF THE OPHTHALMIC SHARES. So long as the
security interests granted to the Purchasers under the Security Agreement
Amendment and the IP Security Agreement Amendment shall be in effect the Company
shall not without the prior written consent of the Purchasers pledge, sell,
transfer, or assign or otherwise dispose of the Ophthalmic Shares.

                                  MISCELLANEOUS

         4.1 FEES AND EXPENSES. At the Closing the Company shall reimburse the
Purchasers for their legal fees and expenses incurred in connection with the
preparation and negotiation of the Transaction Documents by paying to Robinson
Silverman $20,000 for the preparation and negotiation of the Transaction

be retained by the Purchasers and shall not be delivered to the Company at the
Closing. Other than the amounts contemplated in the immediately preceding
sentence, and except as otherwise set forth in the Registration Rights

accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and

         4.2 ENTIRE AGREEMENT; AMENDMENTS. The Transaction Documents, together
with the Exhibits and Schedules thereto, and the Transfer Agent Instructions
contain the entire understanding of the parties with respect to the subject
matter hereof and supersede all prior agreements and understandings, oral or
written, with respect to such matters, which the parties acknowledge have been
merged into such documents, exhibits and schedules.

         4.3 NOTICES. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be

Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not

substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

incurred by reason of any breach of its obligations described in the foregoing

responsible in any way for the performance of the obligations of any other
Purchaser hereunder. Nothing contained herein or in any other agreement or
document delivered at any closing, and no action taken by any Purchaser pursuant
hereto or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert with
respect to such obligations or the transactions contemplated by this Agreement.
Each Purchaser shall be entitled to protect and enforce its rights, including
without limitation the rights arising out of this Agreement or out of the
Transaction Documents, and it shall not be necessary for any other Purchaser to
be joined as an additional party in any proceeding for such purpose.

                             MERCER YALE BUILDING
                            OFFICE LEASE AGREEMENT

                             ARTICLE 1.  PREMISES

     Section 1.1   Premises Defined.   Landlord hereby leases to Tenant, and
Tenant hereby leases from Landlord, upon the terms and conditions hereinafter
set forth, those certain premises and improvements consisting of the floor area
and the location described in the Lease Summary and designated on the plans
attached hereto as Exhibit A (hereinafter referred to as the "Premises").  The
Premises are located in the building known as the Mercer Yale Building (the
"Building") which is situated in the City of Seattle, County of King, State of
Washington and located upon the real property described in Exhibit B (the
"Property").  For convenience purposes, portions of the Premises are sometimes
referred to herein as the "Stage I Premises", which includes the Third and
Fourth Floors of the Building, the "Stage II Premises", which includes the
Second Floor of the Building, and the "Stage III Premises", which includes the
First Floor and the Plaza.

     Section 1.2   Alterations.   Landlord and Tenant acknowledge that Exhibit A
sets forth the floor plan for the floor(s) of the Building on which the Premises
is located and the location of the Premises therein.  Landlord may in its sole
discretion increase, decrease, or change the number, locations and dimensions of
any hallways, lobby areas and other improvements shown on Exhibit A that are not
within the Premises.  Landlord reserves the right from time to time (a) to
install, use, maintain, repair, relocate and replace pipes, ducts, conduits,
wires, and appurtenant meters and equipment for service to the Premises or to
other parts of the Building which are above the ceiling surfaces, below the
floor surfaces, within the walls and in the central core areas of the Building
which are located within the Premises or located elsewhere in the Building; (b)
to alter or expand the Building; and (c) to alter, relocate or substitute any of
the Common Areas, as defined in Section 1.4 below.  Landlord further reserves
the right to install at any time vertical risers and associated duct work within
portions of the Premises designed to provide access between the roof of the
Building and all levels of the Building through existing "punch out" areas
located in the slab floors for the installation of cooling towers and other
equipment and apparatus servicing floors beneath the floors comprising the
Premises. Landlord agrees to execute any work permitted pursuant to this Section
1.2 in a manner (x) designed to minimize disruption to Tenant's business
operations and (y) such that such work does not result in additional charges or
expenses to Tenant (except to the extent that the cost of such work constitutes
an Operating Expense pursuant to Section 4.2.6).

     Section 1.3   Condition of Premises.   The Premises are leased by Landlord
and accepted by Tenant in an "as is" condition, subject to any improvements,
alterations or modifications to be made pursuant to Article 7 below, and the
requirement of Landlord to complete the improvements specified therein.

     Section 1.4   Common Areas.   So long as Tenant occupies the Premises under
the terms of this Lease, Tenant, its licensees, invitees, customers and
employees shall have the non-exclusive right to use all entrances, lobbies, and
other public areas of the Building (the "Common Areas") in common with Landlord,
other Building tenants, and their respective licensees, invitees, customers and
employees.  The use of the Common Areas shall be subject to the terms and
conditions of this Lease.

                     ARTICLE 2.  BUSINESS PURPOSE AND USE

     Section 2.1   Permitted Uses.   Tenant shall use the Premises solely for
the purposes specified in the Lease Summary, and for no other business or
purpose without the prior written consent of the Landlord.

                                       1
<PAGE>

     Section 2.2   Prohibited Uses.   Tenant shall not do or permit anything to
be done in or about the Premises, nor bring or keep anything therein, which will
(a) in any way increase the existing rate of or adversely affect any policy of
fire or other insurance upon the Building or any of its contents, or cause a
cancellation of any insurance policy covering any part thereof or any of its
contents; (b) obstruct or interfere in any way with the rights of other tenants
or occupants of the Building or injure or unreasonably annoy any of them; or (c)
use or allow the Premises to be used for any improper, unlawful or objectionable
purposes.  Tenant shall not cause, maintain or permit any nuisance in, on or
about the Premises, nor shall Tenant commit or suffer to be committed any waste
in, on or about the Premises.  Tenant shall not place upon or install in windows
or other openings any signs, symbols, drapes, or other material without written
approval of Landlord (subject to Tenant's right to install a sign on the
Building as set forth in Exhibit E).  Tenant shall not place any object or
barrier within, or otherwise obstruct, any of the Common Areas.

     Section 2.3   Compliance With Laws.   Tenant shall at all times comply with
all laws, ordinances and any regulations promulgated by any governmental
authority having jurisdiction over the Building and/or the Premises.  To the
extent Landlord is required by the City of Seattle to maintain carpooling and
public transit programs, Tenant shall use commercially reasonable efforts to
cooperate in the implementation and use of these programs by and among Tenant's
employees.

                               ARTICLE 3.  TERM

     Section 3.1   Term.   The term of this Lease shall commence on the first
day of the calendar month in which the earlier of the following dates occurs
(such first day of the calendar month shall be referred to as the "Lease
Commencement Date"):

          3.1.1   The date the "Tenant Improvements" pertaining to the Stage I
Premises and which are described in Part II of Exhibit C are approved by the
appropriate governmental agency as being in accordance with its building code
and the building permit issued for such improvements, as evidenced by the
issuance of a final building inspection approval; or

          3.1.2   The date Landlord's architect and general contractor have
both certified in writing to Tenant that the Tenant Improvements pertaining to
the Stage I Premises which are described in Part II of Exhibit C have been
substantially completed in accordance with the plans and specifications
therefor; or

          3.1.3   The date that Tenant takes possession or beneficial occupancy
of all or any portion of the Premises.

provided, that if the first to occur of Sections 3.1.1, 3.1.2 or 3.1.3 above
falls on a day other than the first day of a calendar month, Tenant's rent and
other obligations pursuant to this Lease for the first month of the Lease Term
(as defined below) shall be prorated based upon the number of days from and
including the first to occur of Sections 3.1.1, 3.1.2 or 3.1.3 above to the end
of such first month.

From the Lease Commencement Date, the term of this Lease shall continue for the
time period specified in the Lease Summary, the expiration of which shall be the
Termination Date of this Lease, unless this Lease is sooner terminated as
hereinafter provided.  The period between the Lease Commencement Date and the
Termination Date shall be referred to as the "Lease Term" or "Term".  The
Landlord and Tenant acknowledge that certain obligations under the provisions of
this Lease may be binding upon them prior to the Lease Commencement Date, such
as, but not limited to, the provisions of Exhibit C, and Landlord and Tenant
shall be bound by such provisions prior to the Lease Commencement Date.

                                       2
<PAGE>

     Section 3.2   Lease Year.   "Lease Year" shall mean that period of twelve
(12) consecutive months which ends on December 31 of each year and which falls
within the Term of this Lease; provided, however, the first Lease Year (which
may be a partial Lease Year) shall mean that period from the Lease Commencement
Date until the December 31 first occurring after the Lease Commencement Date and
the last Lease Year (which may be a partial Lease Year) shall mean that period
from the January 1st last occurring during the Term of this Lease until the
Termination Date.

     Section 3.3   Possession by Tenant.

          3.3.1   Landlord shall deliver to Tenant, and Tenant shall accept from
Landlord, possession of the Premises, upon the date of substantial completion of
the "Tenant Improvements" for the Stage I Premises described in Part II of
Exhibit C. Certification by Landlord's architect (the "Project Architect") and
Landlord's general contractor as to the substantial completion of the Tenant
Improvements shall be conclusive and binding upon Landlord and Tenant.

          3.3.2   If Landlord cannot deliver possession of the Premises to
Tenant by the Target Lease Commencement Date, as specified in the Lease Summary,
then this Lease shall not be void or voidable, nor shall Landlord be liable to
Tenant for any loss or damage resulting therefrom, but in that event all Rent
shall be abated until the Landlord delivers possession of the Premises to Tenant
in the condition described in the first sentence of Section 3.3.1 (except to the
extent any such delay is caused by Tenant or anyone acting through or on behalf
of Tenant).

                               ARTICLE 4.  RENT

     Section 4.1   Basic Rent.

          4.1.1   Tenant shall pay to Landlord as minimum rental for the use and
occupancy of the Premises the "Basic Rent" as specified in the Lease Summary.
Basic Rent shall be payable in Monthly Rent Installments of the amount specified
in the Lease Summary, with the Monthly Rent Installment attributable to each
month of the Lease Term payable on or before the 25th day of the preceding
month. The first Monthly Rent Installment shall be due on or before the Lease
Commencement Date. Basic Rent for any partial year shall be prorated based upon
the actual number of months left in such partial year. The Monthly Rent
Installment for any partial month shall be prorated based upon the actual number
of days in that partial month. The Basic Rent set forth in the Lease Summary
shall not be adjusted (either upward or downward) despite subsequent
measurements of the rentable area of the Premises which identify discrepancies
between the actual area and that shown in the Lease Summary.

          4.1.2   Notwithstanding the foregoing, Tenant shall pay to Landlord
the Basic Rent shown in the Lease Summary for Month 01 of the Term for the Stage
III Premises (i.e., $26.00 per RSF per month) on or before April 25, 2000
(respecting the Basic Rent corresponding to the month commencing May 1, 2000),
regardless of whether the Lease Commencement Date occurs before or after May 1,
2000.

     Section 4.2   Operating Expenses.

          4.2.1   This is a "triple net lease". With respect to each Lease Year
commencing with the first Lease Year, and commencing as of the Lease
Commencement Date, the Tenant shall pay, in monthly installments and as
"Additional Rent", an amount equal to the "Tenant's Proportionate Share" (as
hereinafter defined) of actual "Total Operating Expenses" (as hereinafter
defined). The monthly installment of Additional Rent attributable to each month
during the Lease Term shall be due and payable on the 25th day of the
immediately preceding month. Notwithstanding anything herein to the contrary,
Tenant shall in no event pay less than the Basic Rent in any calendar year.

                                       3
<PAGE>

          4.2.2   "Tenant's Proportionate Share" shall be computed by dividing
the Total Rentable Area of the Premises by the Total Rentable Area of the
Building. Tenant's Proportionate Share upon the Lease Commencement Date for the
entire Premises is as specified in the Lease Summary.

          4.2.3   "Rentable Area of the Building" and "Rentable Area of the
Premises" are defined as those areas obtained by measuring the Building and
Premises using Landlord's method of measurement, which method is based
substantially on the method of measuring floor area in office buildings
specified in the American National Standard Publication ANSI/BOMA Z65.1-1996
published by the Building Owners and Managers Association International
(otherwise known as "BOMA Standard").  The Total Rentable Area of the Building
and Total Rentable Area of the Premises, as of the Lease Commencement Date, are
as specified in the Lease Summary.  The Total Rentable Area of the Premises
exceeds the usable area of the Premises to include a pro rata share of hallways,
restrooms, and other common elements located on the floor on which the Premises
are located.

          4.2.4    Landlord shall provide Tenant with a written estimate of
Total Operating Expenses for the first Lease Year not later than the Lease
Commencement Date. Landlord shall provide Tenant with a written estimate of
Total Operating Expenses for each succeeding year not later than sixty (60) days
after the start of each Lease Year during the Lease Term. Tenant shall then pay
to Landlord, monthly in advance, one-twelfth (1/12) of Tenant's Proportionate
Share of the estimated Total Operating Expenses for the said Lease Year. In the
event any item of actual Operating Expenses, including without limitation those
items identified in subparagraph 4.2.6 below, increases five percent (5%) or
more in price or cost over any twelve (12) month period, Landlord shall have the
option to proportionally increase the amount of Tenant's monthly remittance on
account of any such increase upon thirty (30) days' written notice from Landlord
to Tenant.

          4.2.5   Within one hundred twenty (120) days after the end of every
Lease Year during the Lease Term, Landlord shall provide the Tenant with a
written statement of the actual Total Operating Expenses for that Lease Year.
If the actual Total Operating Expenses should exceed the estimated amount with
respect to such Lease Year, then Tenant shall pay Landlord the additional amount
due to the Landlord within thirty (30) days and, if actual Total Operating
Expenses should be less than the estimated Total Operating Expenses for that
Lease Year, then Landlord shall credit, against future Additional Rent due under
this Article, the amount of any overpayment by Tenant; provided, that if any
overpayment by Tenant exists at the Termination Date, Landlord shall remit to
Tenant the amount of any such overpayment within thirty (30) days of the date of
determination.

          4.2.6   "Operating Expenses" as used herein shall mean all costs,
expenses and other charges incurred by Landlord in connection with the
ownership, operation, repair and maintenance of the Property and the Building as
an office building in Seattle, Washington, including but not limited to:

               4.2.6.1   Wages, salaries and fringe benefits of all employees
and contractors engaged in the management, operation and maintenance of the
Property and/or the Building (but only to the extent so engaged); employer's
Social Security taxes, unemployment taxes or insurance, and any other taxes
which may be levied against Landlord on those wages and salaries; and the cost
to Landlord of disability and hospitalization insurance and pension or
retirement benefits for these employees;

               4.2.6.2   All supplies and materials used in the operation and
maintenance of the Property and/or the Building;

               4.2.6.3   Cost of water and power, and cost of heating, lighting,
air conditioning and ventilating the Building, the Common Areas and the
Premises, which costs shall be based on either Tenant's Proportionate Share or
separately allocated to the Premises, at Landlord's option, based upon either
direct usage, if separately metered, or an appropriate allocation among all
tenants consuming those services as measured from the meter monitoring this
usage;

                                       4
<PAGE>

               4.2.6.4   The electrical costs incurred in the operation of the
"chiller" for the Building, which shall be allocated pro rata among the Building
tenants;

               4.2.6.5   Cost of maintenance, depreciation and replacement of
machinery, tools and equipment (if owned by Landlord) and for rental paid for
such machinery, tools and equipment (if rented) used in connection with the
operation or maintenance of the Building maintenance (except that if such
equipment is used at a location other than the Property, all costs attributable
to such equipment shall be allocated proportionately to the Property based on
the ratio of the number of hours of operation at the Property during a specific
time period [such as a month, Lease Year, calendar year or fiscal year] divided
by the total number of hours of operation of such equipment at all locations
during the same time period);

               4.2.6.6   All premiums and deductibles on policies of
compensation, public liability, property damage, automobile, garage keepers,
rental loss and any other policies of insurance maintained by Landlord with
respect to the Property, Building or any insurable interest therein. Cost of
casualty and liability insurance applicable to the Property and/or the Building,
the improvements therein, and Landlord's personal property used in connection
therewith;

               4.2.6.7   Cost of janitorial services, repairs and general
maintenance;

               4.2.6.8   Any capital improvements made or installed (a) to be in
compliance with any applicable government statutes, ordinances, regulations or
other requirements, and (b) for purposes of saving labor or otherwise reducing
applicable operating costs amortized over the useful life of such improvements,
as determined by Landlord in accordance with generally accepted accounting
principles and practices in effect at the time of acquisition of the capital
item;

               4.2.6.9   Costs in connection with maintaining and operating any
garage owned by the Landlord for use by tenants of the Building;

               4.2.6.10   All taxes and assessments and governmental charges
whether federal, state, county or municipal and any other taxes and assessments
attributable to the Property and/or the Building or its operation, including
without limitation real property taxes and assessments and any tax or other
levy, however denominated, on or measured by the rental collected by the
Landlord with respect to the Building, or on Landlord's business of leasing the
Building, but excluding federal and state taxes on income and corporate
franchise taxes (Any such assessments which are payable in installments shall
only be included in Operating Expenses to the extent Landlord had elected to pay
the same over the longest installment permitted by the jurisdiction imposing
such assessment and Tenant shall not be responsible for the portion thereof
attributable to periods not included in the Lease Term. If at any time during
the Lease Term a tax, license fee or excise on rents or other tax, however
described, is levied or assessed against Landlord on account of the rent
expressly reserved hereunder, as a substitute in whole or in part for taxes
levied or assessed on land and buildings or on land or buildings, such tax or
excise on rents or other tax shall be included within the definition of
Operating Expenses, but only to the extent of the amount thereof which is
lawfully levied, assessed or imposed as a direct result of Landlord's ownership
of this Lease or of the rentals accruing under this Lease);

               4.2.6.11   The cost of maintaining any public transit system,
vanpool, or other public or semi-public transportation imposed upon Landlord's
ownership and operation of the Building;

               4.2.6.12   Cost of all accounting and other professional fees
incurred in connection with the operation of the Property and/or the Building;

               4.2.6.13   A management fee, not to exceed current market rates,
which may be payable to the Landlord;

                                       5
<PAGE>

               4.2.6.14   Cost of replacing lamps, bulbs, starters and ballasts
used in the Building, other than those for which the cost is billed directly to
a tenant.

     Notwithstanding the foregoing, Operating Expenses shall not include
expenses for which the Landlord is reimbursed or indemnified (either by an
insurer, condemnor, tenant or otherwise); expenses incurred in leasing or
procuring tenants (including, without limitation, lease commissions, legal
expenses, advertising costs, and expenses of renovating space for tenants);
legal, accounting and other expenses arising out of disputes with tenants or
other occupants of the Building, the enforcement of the provisions of any lease
of space in the Building or the defense of Landlord's title to or interest in
the Property, Building or any portion of either; fines or penalties incurred due
to violations by Landlord of any governmental rule or authority; provided that
if, as a consequence of any such violation, Landlord is required to incur costs
on an ongoing basis which are in the nature of Operating Expenses as described
herein, such costs shall be included in Operating Expenses; except as provided
in Section 4.2.6.1, Landlord's general corporate overhead and general
administrative expenses (excluding reimbursement of out-of-pocket costs for
postage, photocopies, and telephone costs incurred in operating the Building);
interest or amortization payments on any mortgage or mortgages, and rental under
any ground or underlying lease or leases; costs of any work or service performed
for or facilities furnished to a tenant at the tenant's cost; the cost of
correcting defects (latent or otherwise) in the construction, design,
workmanship or material of the Building, except those conditions (not occasioned
by construction defects) resulting from wear and tear shall not be deemed
defects; and costs of capital improvements and depreciation and amortization
(except as provided in Section 4.2.6.8 or otherwise above). Landlord and Tenant
shall each from time to time upon request of the other sign a written memorandum
confirming the amount of the Additional Rent as adjusted from time to time
hereunder. Landlord shall not collect in excess of one hundred percent (100%) of
the Total Operating Expenses for any Lease Year and shall not recover any item
of cost more than once. In computing Operating Expenses for any period, if less
than one hundred percent (100%) of the rentable square feet of the Building are
occupied by tenants during such period, the amount of Operating Expenses will be
deemed to be increased to an amount equal to the like Operating Expenses which
would have been incurred in Landlord's reasonable judgment had such occupancy
been one hundred percent (100%) of the rentable square feet of the Building
during such period.

          4.2.7   Tenant shall have the right, upon fulfillment of the
conditions set forth below, to conduct one (1) audit of the Landlord's books and
records covering the Operating Expenses for a particular calendar year to verify
the accuracy of the Landlord's determination of the Operating Expenses for such
period. The conditions which must be met before Tenant shall have the right to
audit the books and records of a particular calendar year are as follows:

               4.2.7.1   Tenant must provide Landlord not less than thirty (30)
days' prior written notice of the Tenant's election to audit (the "Tenant's
Notice of Audit"), together with the information concerning the auditor as
outlined in subsection 4.2.7.4 below, which Tenant's Notice of Audit and
information must be delivered to Landlord within thirty (30) days after Tenant's
receipt of the Landlord's statement of actual Operating Expenses for a
particular calendar year.

               4.2.7.2   Tenant's audit must be undertaken and completed by
Tenant or its agents at reasonable times during Landlord's normal business hours
at the place where the Landlord's records are kept. Said audit must be commenced
within ninety (90) days of Tenant's receipt of the Landlord's statement of
Operating Expenses for a particular calendar year and completed within a
reasonable time of commencement.

               4.2.7.3   Tenant shall not entitled to conduct an audit if
Landlord has delivered written notice to Tenant that Tenant is in default under
this Lease.

               4.2.7.4   At the time the Tenant delivers its Tenant's Notice of
Audit to Landlord, the Tenant shall also provide evidence that the audit will be
a "fair and true audit." For the purposes hereof, the term "fair and true audit"
shall mean that the review of the subject books and records shall be undertaken
and completed by the Tenant, its officers or employees, or by an independent
accounting firm being paid on an hourly basis and that in no event will the
party auditing the books (or that

                                       6
<PAGE>

party's employer or principal) directly or indirectly base the compensation or
fees for such audit work upon a percentage of the savings found or the return
due the Tenant by reason of that audit.

               4.2.7.5   The Tenant's rights to audit the Landlord's books and
records shall be strictly limited to the right set forth above and the Tenant
shall have no right to audit any of the Landlord's books or records for any
calendar year before or after the Lease Term or for any calendar year other than
the immediately preceding calendar year as set forth above. All costs and
expenses of the audit shall be borne solely by the Tenant.

               4.2.7.6   A true and correct copy of the audit shall be delivered
to the Landlord within fifteen (15) days of the completion of such audit if
Tenant requests a credit for overpayment. Any overpayment shown by such audit
shall be subject to the Landlord's prompt verification and, upon such
verification, shall be given to the Tenant as a credit against Operating
Expenses next falling due or, if after the expiration of the Term, shall be
promptly paid directly to Tenant.

     Section 4.3   Rent.   The terms "Rent" and "Rental" as used in this Lease
shall mean all amounts to be paid hereunder by Tenant whether those sums are
designated as Basic Rent, Additional Rent or the amounts payable for the
Stipulated Parking Spaces, all as the same may be adjusted by the terms of this
Lease.  Failure by Tenant to pay any sum of Rent as defined under this Article 4
shall entitle Landlord to pursue any or all remedies specified in this Lease as
well as remedies specified in RCW Chapter 59.12 or otherwise allowed by law.

     Section 4.4   Place of Payment.   All Rent shall be paid to the Landlord on
or before the 25th day of the calendar month preceding the month to which the
particular item comprising the Rent relates, at the address to which notices to
Landlord are to be given.  All Rental payments to be made hereunder, whether
Basic Rent, or Additional Rent or otherwise, are to be made without deduction,
setoff, prior notice or demand by Landlord.

                           ARTICLE 5.  PREPAID RENT

     Section 5.1   Prepaid Rent.   Contemporaneously with Tenant's execution of
this Lease, Tenant shall pay to Landlord the sum set forth as Prepaid Rent in
the Lease Summary to be applied to Basic Rent for the month during the Term
hereof as specified in the Lease Summary.  In the event Tenant defaults under
the terms of this Lease prior to the application of the Prepaid Rent, such sums
shall not be applicable to the Basic Rent as set forth in the Lease Summary but
shall be held by Landlord as a security deposit for the full and faithful
performance of every provision of this Lease to be performed by Tenant.

                               ARTICLE 6.  TAXES

     Section 6.1   Personal Property Taxes.   Tenant shall pay before
delinquency all license fees, public charges, property taxes and assessments on
the furniture, fixtures, equipment and other property of or being used by Tenant
at any time situated on or installed in the Premises.

     Section 6.2   Business Taxes.   Tenant shall pay before delinquency all
taxes and assessments or license fees levied, assessed or imposed by law or
ordinance, by reason of the use of the Premises for the specific purposes set
forth in this Lease.

                                       7
<PAGE>

     Section 6.3   Right to Contest.   Notwithstanding the foregoing, Tenant
shall have the right to contest the validity or amount of any taxes,
assessments, duties or fees contemplated by Sections 6.1 or 6.2 as long as
Tenant first provides such security in lieu of payment as Landlord may
reasonably require and Landlord's interest in the Premises or the Property is
not rendered subject to forfeiture, sale or disturbance. In such case, during
the bona fide period of such contest, Tenant will not be in default hereunder.
However, upon final determination of such contest, Tenant must immediately pay
the amount found to be due thereby, if any, together with all costs, penalties
or interest. After such payment, Tenant will be entitled to the release of any
security.

               ARTICLE 7.  MAINTENANCE, REPAIRS AND ALTERATIONS

     Section 7.1   Landlord's and Tenant's Improvements.   Landlord and Tenant
shall, each at its own expense, complete and install in a good and workmanlike
manner within the Stage I Premises those items specified as the "Landlord's
Work" and "Tenant's Work", respectively, on Exhibit C attached hereto.

     Section 7.2   Services to Be Furnished by Landlord.   Provided Tenant is
not in default under any of the provisions of this Lease, and subject to
reimbursement pursuant to Section 4.2 above, Landlord shall provide the
following services during standard hours of operation of the Building.  These
standard hours of operation are 8 a.m. to 6 p.m., Monday through Friday.

          7.2.1   Public utilities shall be caused to furnish the Premises with
electricity and water utilized in operating any and all facilities serving the
Premises;

          7.2.2   Hot and cold water at those points of supply provided for
general use of other tenants in the Building, central heat and air conditioning
in season, at such times as Landlord normally furnishes these services to other
tenants in the Building and at temperatures and in amounts as are considered by
Landlord to be standard, but this service at times during the weekdays at other
than standard hours of operation for the Project, on weekends and holidays shall
be furnished only upon request of Tenant, who shall bear the entire costs
thereof in respect to the Premises;

          7.2.3   Routine maintenance, painting and electric lighting service
for all Common Areas and special service areas of the Building in the manner and
to the extent deemed by Landlord to be standard and consistent with the
operation and maintenance of the Building as a first-class office building in
Seattle, Washington;

          7.2.4   Janitorial service on a five (5) day week basis, excluding
Fridays, Saturdays, and legal holidays;

          7.2.5   Electrical facilities to provide sufficient power for
typewriters, personal computers and other small office machines of similar low
electrical consumption, but not including electricity required for electronic
data processing equipment, special lighting in excess of building standard, and
any other item of electrical equipment which (itself) consumes more than .5
kilowatts per hour at rated capacity or requires a voltage other than 120 volts
single phase per square foot. If any electrical equipment installed in the
Premises requires air conditioning capacity above that provided by the building
standard system, then the additional air conditioning installation and
corresponding operating costs will be the separate obligation of the Tenant; and

          7.2.6   Security for the Building; provided, however, Landlord shall
not be liable to Tenant or any employee, invitee, licensee or sublessee of
Tenant for bodily injury, property damage, or other losses or damages due to
theft, burglary, or other criminal activities occurring in or about the
Building.

In the event Tenant desires any of the aforementioned services in amounts in
excess of those deemed by Landlord to be "standard" and in the event Landlord
elects to provide these additional services, Tenant

                                       8
<PAGE>

shall pay Landlord as Additional Rent hereunder the cost of providing these
additional services. Failure by Landlord to any extent to furnish any of the
above services, or any cessation thereof, resulting from causes beyond the
control of Landlord, shall not render Landlord liable in any respect for damages
to either person or property, nor shall that event be construed as an eviction
of Tenant, nor result in an abatement of Rent, nor relieve Tenant from any of
Tenant's obligations hereunder (including, but not limited to, the payment of
Rent). Should any of the equipment or machinery utilized in supplying the
services listed herein for any cause cease to function properly, Landlord shall
use commercially reasonable diligence to repair that equipment or machinery
promptly, but Tenant shall have no right to terminate this Lease, and shall have
no claim for a reduction, abatement or rebate of Rent or damages on account of
any interruption in service occasioned thereby or resulting therefrom.

     Section 7.3   Tenant's Maintenance and Repairs.   Tenant shall be obligated
to maintain and to make all repairs, replacements or additions of any kind
whatsoever to all personal property located within the Premises and to all trade
fixtures, furnishings and carpet located within the Premises. Tenant shall keep
all such items in good condition, subject to ordinary wear and tear. Tenant also
shall be responsible for maintaining and replacing all specialty lamps, bulbs,
starters and ballasts.

     Section 7.4   Tenant's Alterations.   Subject to Landlord's prior written
approval, Tenant may make, at its expense, additional improvements or
alterations to the Premises which it may deem necessary or desirable. Landlord's
approval to any improvements or alterations may be withheld in Landlord's sole
discretion if such improvements or alterations require any other alteration,
addition, or improvement to be performed or made to any portion of the Building
other than the Premises. Any repairs or new construction by Tenant shall be done
in compliance with all applicable laws, rules, and regulations (including,
without limitation, the Americans with Disabilities Act of 1990 (the "ADA")) and
in conformity with plans and specifications approved by Landlord and shall be
performed by a licensed contractor approved by Landlord; provided, however,
Landlord's consent to any alterations or improvements, or Landlord's approval of
plans and specifications for such alterations or improvements shall create no
responsibility or liability on the part of Landlord for their completeness,
design sufficiency, or compliance with all laws, rules, and regulations
(including, without limitation, the ADA). If requested by Landlord, Tenant shall
post a bond or other security satisfactory to Landlord to protect Landlord
against liens arising from work performed for Tenant. All work performed shall
be done in a workmanlike manner and with materials of the quality and appearance
as exist throughout the Building. Landlord may require Tenant to remove and
restore any improvements or alterations on the termination of this Lease in
accordance with Section 13.2 below.

     Section 7.5   Liens.   Tenant shall keep the Premises and the Building free
from any liens arising out of any work performed, material furnished, or
obligations incurred by Tenant.  If Tenant disputes the correctness or validity
of any claim of lien, Tenant shall, within ten (10) days after written request
by Landlord, post or provide security in a form and amount acceptable to
Landlord to insure that title to the Property remains free from the lien
claimed.

                            ARTICLE 8.  INSURANCE

     Section 8.1   Use; Rate.   Tenant shall not do anything in or about the
Premises which will in any way tend to increase insurance rates paid by Landlord
on policies of liability or casualty insurance maintained with respect to the
Building and/or Property.  In no event shall Tenant carry on any activities
which would invalidate any insurance coverage maintained by Landlord.

     Section 8.2   Liability Insurance.   Tenant shall during the Lease Term, at
its sole expense, maintain in full force a policy or policies of commercial
general liability insurance issued by one or more insurance carriers, insuring
against liability for injury to or death of persons and loss of or damage to
property occurring in or on the Premises and any portion of the Common Area
which is subject to Tenant's exclusive control.  Said liability insurance shall
be in an amount not less than Two Million Dollars ($2,000,000.00) combined
single limit for bodily and personal injury and property damage per occurrence
and not less than Five Million Dollars ($5,000,000.00) in the aggregate.

     Section 8.3   Worker's Compensation Insurance.   Tenant shall at all times
maintain Worker's Compensation Insurance in compliance with Washington law.

     Section 8.4   Casualty Insurance.   Tenant shall pay for and shall maintain
in full force and effect during the Term of this Lease a standard form policy or
policies of property and all-risk coverage with an extended coverage endorsement
covering all interior and storefront glass, whether plate or otherwise, stock in
trade, trade fixtures, equipment, and other personal property located in the
Premises and used by Tenant in connection with its business.

     Section 8.5   Compliance With Regulations.   Tenant shall, at its own
expense, comply with all requirements, including installation of fire
extinguishers, or automatic dry chemical extinguishing systems, required by
insurance underwriters or any governmental authority having jurisdiction
thereover, necessary for the maintenance of reasonable fire and extended
insurance for the Premises and/or Building.

     Section 8.6   Waiver of Subrogation.   Any property and all-risk coverage
insurance carried by Landlord or Tenant insuring, in whole or in part, the
Building and/or the Premises, including improvements, alterations and changes in
and to the Premises made by either of them, and Tenant's trade fixtures therein
shall be written in such a manner as to permit the waiver of rights of
subrogation prior to loss by either party against the other in connection with
loss or damage covered by the policies involved. So long as the policy or
policies can be so written and maintained in effect, neither Landlord nor Tenant
shall be liable to the other for any such loss or damage. Either party shall,
upon request by the other party, furnish such other party evidence of its
compliance with this Section 8.6.

     Section 8.7   General Requirements.

          8.7.1   All policies of insurance required to be carried hereunder by
Tenant shall be written by companies licensed to do business in Washington and
which have A.M. Best rating of not less than A:XIII or better in the "Best's Key
Rating Guide". Tenant shall, when requested by Landlord, furnish Landlord with a
certificate evidencing insurance required to be maintained by Tenant pursuant to
this Article 8 and shall satisfy Landlord that each such policy is in full force
and effect.

          8.7.2   The commercial general liability insurance required to be
carried under Section 8.2 above shall be primary and non-contributing with the
insurance carried by Landlord.

          8.7.3   Each policy required under Sections 8.2 and 8.4 shall
expressly include, severally and not collectively, as named or additionally
named insured thereunder, the Landlord, Landlord's property manager, and any
person or firm designated by the Landlord and having an insurable interest
thereunder, hereinafter called "Additional Insured," as their respective
interests may appear.

          8.7.4   All insurance policies maintained by Tenant shall not be
subject to cancellation in coverage except upon at least thirty (30) days' prior
written notice to Landlord. The policies of insurance or duly executed Accord
Form 27, Evidence of Property Insurance Forms evidencing such policies, together
with satisfactory evidence of the payment of premiums thereon, shall be
deposited with Landlord.

          8.7.5   If the Tenant fails to procure and maintain insurance as
required by this Article 8, the Landlord may obtain such insurance and keep it
in effect, and the Tenant shall pay to Landlord the premium cost thereof, upon
demand and as Additional Rent, with interest as provided in Section 21.7 below
from the date of payment by the Landlord to the date of repayment by the Tenant.

          8.7.6   The limits of any insurance maintained by Tenant pursuant to
this Article 8 shall in no way limit the liability of Tenant under this Lease.

     Section 8.8   Blanket Insurance.   The Tenant may fulfill its insurance
obligations hereunder by maintaining a so-called "blanket" policy or policies of
insurance in a form that provides by specific

                                      10
<PAGE>

endorsement coverage not less than that which is required hereunder for the
particular property or interest referred to herein; provided, however, that the
coverage required by this Article 8 will not be reduced or diminished by reason
of use of such blanket policy of insurance.

                   ARTICLE 9.  DESTRUCTION AND CONDEMNATION

     Section 9.1   Total or Partial Destruction.

          9.1.1   In the event the Building and/or the Premises is damaged by
fire or other perils covered by Landlord's insurance, Landlord shall:

               9.1.1.1   In the event of Total Destruction, either Landlord or
Tenant may elect to terminate this Lease by written notice delivered to the
other not later than sixty (60) days after the event causing the Total
Destruction. In the event neither party delivers such notice, the Lease shall
remain in effect, subject to the remaining provisions of this Section 9.1. As
used herein, the term "Total Destruction" means damage to the Building and/or
Premises exceeding fifty percent (50%) of the full insurable value thereof.

               9.1.1.2   In the event of partial destruction of the Building
and/or the Premises, to an extent not exceeding fifty percent (50%) of the full
insurable value thereof, and if the damage thereto is such that the Building
and/or the Premises may be repaired, reconstructed or restored within a period
of ninety (90) days from the date of the discovery of such casualty, and if
Landlord will receive insurance proceeds sufficient to cover the cost of such
repairs, then Landlord shall commence and proceed diligently with the work of
repair, reconstruction and restoration and this Lease shall continue in full
force and effect. If such work of repair, reconstruction and restoration shall
require a period longer than ninety (90) days or exceeds fifty percent (50%) of
the full insurable value thereof, or if said insurance proceeds will not be
sufficient to cover the cost of such repairs, then Landlord either may elect to
so repair, reconstruct or restore and the Lease shall continue in full force and
effect or Landlord may elect not to repair, reconstruct or restore and the Lease
shall then terminate. Under any of the conditions of this Section 9.1.1.2,
Landlord shall give written notice to Tenant of its intention within sixty (60)
days after Landlord's discovery of such partial destruction. In the event
Landlord elects not to restore the Building and/or the Premises, this Lease
shall be deemed to have terminated as of the date possession of the Premises is
surrendered to Landlord.

          9.1.2   Upon any termination of this Lease under any of the provisions
of this Section 9.1, the parties shall be released without further obligation to
the other from the date possession of the Premises is surrendered to Landlord
except for items which have therefore accrued and are then unpaid.

          9.1.3   In the event of repair, reconstruction and restoration by
Landlord as herein provided, the rental payable under this Lease shall be abated
proportionately with the degree to which Tenant's use of the Premises is
impaired during the period of such repair, reconstruction or restoration;
provided that there shall be no abatement of rent if such damage is the result
of Tenant's negligence or intentional wrongdoing.  Tenant shall not be entitled
to any compensation or damages for loss in the use of the whole or any part of
the Premises and/or any inconvenience or annoyance occasioned by such damage,
repair, reconstruction or restoration.  Tenant shall not be released from any of
its obligations under this Lease except to the extent and upon the conditions
expressly stated in this Section 9.1.  Notwithstanding anything to the contrary
contained in this Section 9.1, if Landlord is delayed or prevented from
repairing or restoring the damaged Premises within one (1) year after the
discovery of such damage or destruction by reason of acts of God, war,
governmental restrictions, inability to procure the necessary labor or
materials, or other cause beyond the control of Landlord, Landlord, at its
option, may terminate this Lease, whereupon Landlord shall be relieved of its
obligation to make such repairs or restoration and Tenant shall be released from
its obligations under this Lease as of the end of said one year period.

                                      11
<PAGE>

          9.1.4   If damage is due to any cause other than fire or other peril
covered by extended coverage insurance, Landlord may elect to terminate this
Lease.

          9.1.5   If Landlord is obligated to or elects to repair or restore as
herein provided, Landlord shall be obligated to make repair or restoration only
of those portions of the Building and the Premises which were originally
provided at Landlord's expense, and the repair and restoration of items not
provided at Landlord's expense shall be the obligation of Tenant.

          9.1.6   Notwithstanding anything to the contrary contained in this
Section 9.1, Landlord shall not have any obligation whatsoever to repair,
reconstruct or restore the Premises when the damage resulting from any casualty
covered under this Section 9.1 is discovered during the last twelve (12) months
of the Term of this Lease or any extension hereof.

          9.1.7   Landlord and Tenant hereby waive the provisions of any
statutes or court decisions which relate to the abatement or termination of
leases when leased property is damaged or destroyed and agree that such event
shall be exclusively governed by the terms of this Lease.

     Section 9.2   Condemnation.   If the whole of the Building or the Premises,
or such portion thereof as shall be required for its reasonable use, shall be
taken by virtue of any condemnation or eminent domain proceeding, this Lease
shall automatically terminate as of the date of the condemnation, or as of the
date possession is taken by the condemning authority, whichever is later.
Current Rent shall be apportioned as of the date of the termination.  In case of
a taking of a part of the Building not required for the reasonable use of the
Premises, then this Lease shall continue in full force and effect and the Rental
shall be equitably reduced based upon the proportion by which the Rentable Area
of the Premises is reduced.  This Rent reduction shall be effective on the date
of the partial taking.  No award, settlement in lieu of an award, or any partial
or entire taking shall be apportioned, and Tenant hereby assigns to Landlord any
award or settlement in lieu of an award which may be made in the taking or
condemnation proceeding, together with any and all rights of Tenant now or
hereafter arising in or to the same or any part thereof; provided that nothing
herein shall prevent Tenant from making a separate claim against the condemning
authority for the taking of Tenant's personal property and/or moving costs so
long as such claim in no way affects the award to be received by Landlord.

     Section 9.3   Sale Under Threat of Condemnation.   A sale by Landlord to
any authority having the power of eminent domain, either under threat of
condemnation or while condemnation proceedings are pending, shall be deemed to
be a taking under the power of eminent domain for all purposes under this
Article 9.

                       ARTICLE 10.  INDEMNITY AND WAIVER

     Section 10.1   Indemnity.

          10.1.1   Tenant, as a material part of the consideration to be
rendered to Landlord, and subject to subsection 10.1.2 below, hereby agrees to
defend, indemnify, and hold Landlord harmless against any and all claims, costs,
and liabilities, including reasonable attorneys' fees and costs (including costs
and fees associated with any lawsuit or appeal), arising by reason of any injury
or claim of injury to person or property, of any nature and howsoever caused,
arising out of the use, occupation and/or control of the Premises, or from any
breach of the terms of this Lease, or any violation of any governmental or
insurance requirements by Tenant, its sublessees, assignees, invitees, agents,
employees, contractors, or licensees, except and to the extent as may arise out
of the willful or negligent acts of Landlord or Landlord's agents, employees or
contractors.

          10.1.2   In the event of concurrent negligence of Tenant, its
sublessees, assignees, invitees, agents, employees, contractors, or licensees on
the one hand, and that of Landlord, its agents, employees, or contractors on the
other hand, which concurrent negligence results in injury or damage to persons
or property of any nature and howsoever caused, and relates to the construction,
alteration, repair, addition to, subtraction from, improvement to or maintenance
of the Premises, Common

                                      12
<PAGE>

Areas, or Building, Tenant's obligation to indemnify Landlord as set forth in
this Section 10.1 shall be limited to the extent of Tenant's negligence, and
that of Tenant's sublessees, assignees, invitees, agents, employees, contractors
or licensees, including Tenant's proportional share of costs, attorneys' fees
and expenses incurred in connection with any claim, action or proceeding brought
with respect to such injury or damage. Tenant agrees that it will not assert its
industrial insurance immunity if such assertion would be inconsistent with
Landlord's right to indemnification from Tenant pursuant to this Section 10.1.
The parties agree that this provision was mutually negotiated.

     Section 10.2   Waiver.   All property kept, stored or maintained on the
Premises shall be so kept, stored or maintained at the sole risk of Tenant.
Except in the case of Landlord's negligence or willful misconduct, Landlord
shall not be liable, and Tenant waives all claims against Landlord, for damages
to persons or property sustained by Tenant or by any other person or firm
resulting from the Building or by reason of the Premises or any equipment
located therein becoming out of repair, or through the acts or omissions of any
persons present in the Building (including the Common Areas) or renting or
occupying any part of the Building (including the Common Areas), or for loss or
damage resulting to Tenant or its property from burst, stopped or leaking
sewers, pipes, conduits, or plumbing fixtures, or for interruption of any
utility services, or from any failure of or defect in any electric line,
circuit, or facility, or any other type of improvement or service on or
furnished to the Premises or the Common Areas or resulting from any accident in,
on, or about the Premises or the Common Areas.

                              ARTICLE 11.  DELAYS

     Section 11.1   Delays.   If either party is delayed in the performance of
any covenant of this Lease because of any of the following causes (referred to
elsewhere in this Lease as a "Delaying Cause"): acts of the other party, action
of the elements, war, riot, labor disputes, inability to procure or general
shortage of labor or materials in the normal channels of trade, delay in
transportation, delay in inspections, or any other cause beyond the reasonable
control of the party so obligated, whether similar or dissimilar to the
foregoing, financial inability excepted, then that performance shall be excused
for the period of the delay but shall in no way affect Tenant's obligation to
pay Rent or the length of the Lease Term.

               ARTICLE 12.  ASSIGNMENT, SUBLEASE AND SUCCESSION

     Section 12.1   Consent Required.   Tenant shall not voluntarily or by
operation of law, (1) mortgage, pledge, hypothecate or encumber this Lease or
any interest herein, (2) assign or transfer this Lease or any interest herein,
sublease the Premises or any part thereof, or any right or privilege appurtenant
thereto, or allow any other person (the employees and invitees of Tenant
excepted) to occupy or use the Premises, or any portion thereof, without first
obtaining the written consent of Landlord, which consent shall not be withheld
unreasonably as set forth below in this Section 12, provided that (i) Tenant is
not then in default under this Lease nor is any event then occurring which with
the giving of notice or the passage of time, or both, would constitute a default
hereunder, and (ii) Tenant has not previously assigned or transferred this Lease
or any interest herein or subleased the Premises or any part thereof. When
Tenant requests Landlord's consent to such assignment or subletting, it shall
notify Landlord in writing of the name and address of the proposed assignee or
subtenant and the nature and character of the business of the proposed assignee
or subtenant and shall provide current and prior financial statements for the
proposed assignee or subtenant, which financial statements shall be audited to
the extent available and shall in any event be prepared in accordance with
generally accepted accounting principles. Tenant shall also provide Landlord
with a copy of the proposed sublease or assignment agreement, including all
material terms and conditions thereof. Landlord shall have the option, to be
exercised within thirty (30) days of receipt of the foregoing, to (1) terminate
this Lease as of the commencement date stated in the proposed sublease or
assignment, (2) sublease or take an assignment, as the case may be, from Tenant
of the interest, or any portion thereof, in this Lease and/or the Premises that
Tenant proposes to assign or sublease, on the same terms and conditions as
stated in the proposed sublet or assignment agreement, (3) consent to the
proposed assignment or sublease, or (4) refuse its consent to the proposed
assignment or sublease, providing that such consent shall not be unreasonably
withheld so long as Tenant is not then in default under this Lease nor is any
event then
                                      13
<PAGE>

occurring which with the giving of notice or the passage of time, or both, would
constitute a default hereunder. In the event Landlord elects to terminate this
Lease or sublease or take an assignment from Tenant of the interest, or portion
thereof, in the Lease and/or the Premises that Tenant proposes to assign or
sublease as provided in the foregoing clauses (1) and (2), respectively, then
Landlord shall have the additional right to negotiate directly with Tenant's
proposed assignee or subtenant and to enter into a direct lease or occupancy
agreement with such party on such terms as shall be acceptable to Landlord in
its sole and absolute discretion, and Tenant hereby waives any claims against
Landlord related thereto, including, without limitation, any claims for any
compensation or profit related to such lease or occupancy agreement.

     Section 12.2   Landlord's Consent'.   Without otherwise limiting the
criteria upon which Landlord may withhold its consent, Landlord shall be
entitled to consider all reasonable criteria including, but not limited to, the
following: (1) whether or not the proposed subtenant or assignee is engaged in a
business which, and the use of the Premises will be in an manner which, is in
keeping with the then character and nature of all other tenancies in the
Building, (2) whether the use to be made of the Premises by the proposed
subtenant or assignee will conflict with any so-called "exclusive" use then in
favor of any other tenant of the Building, and whether such use would be
prohibited by any other portion of this Lease, including, but not limited to,
any rules and regulations then in effect, or under applicable Laws, and whether
such use imposes a greater load upon the Premises and the Building services then
imposed by Tenant, (3) the business reputation of the proposed individuals who
will be managing and operating the business operations of the assignee or
subtenant, and the long-term financial and competitive business prospects of the
proposed assignee or subtenant, and (4) the creditworthiness and financial
stability of the proposed assignee or subtenant in light of the responsibilities
involved. In any event, Landlord may withhold its consent to any assignment or
sublease, if (i) the actual use proposed to be conducted in the Premises or
portion thereof conflicts with the provisions of Section 2.1 above or with any
other lease which restricts the use to which any space in the Building may be
put, (ii) the proposed assignment or sublease requires material alterations,
improvements or additions to the Premises or portions thereof, (iii) the portion
of the Premises proposed to be sublet is irregular in shape and/or does not
permit safe or otherwise appropriate means of ingress and egress, or does not
comply with governmental safety and other codes, (iv) the proposed sublessee or
assignee is either a governmental agency or instrumentality thereof; (v) the
proposed sublessee or assignee, or any person or entity which directly or
indirectly, controls, is controlled by, or is under common control with, the
proposed sublessee or assignee, either (x) occupies space in the Building at the
time of the request for consent, or (y) is negotiating with Landlord or has
negotiated with Landlord during the six (6) month period immediately preceding
the date Landlord receives Tenant's request for consent, to lease space in the
Building. As a further condition to any rights Tenant may have under this Lease
to sublet all or any portion of the Premises, Tenant shall offer space for
sublease at a starting base rental rate no lower than Landlord's then current
highest asking base rental rate for other space in the Building which is then on
the market for direct lease. If there is no space in the Building then currently
on the market for direct lease, Tenant shall offer the space for sublease at a
starting base rental rate no lower than a rate which is the average of the
starting rate for Landlord's last two new leases and/or renewals in the
Building, or if Landlord has not entered into two new leases and/or renewals
within the immediately preceding six month period, then Tenant shall offer the
space for sublease at a starting base rental rate no lower than the fair market
rental rate.

     Section 12.3   Terms of Assignment or Sublease; Profit on Approved
Assignment                                     .

          12.3.1   If Landlord approves an assignment or subletting as herein
provided, the assignment or sublease agreement, as the case may be, after
approval by Landlord, shall not be amended without Landlord's prior written
consent, and shall contain a provision directing the assignee or subtenant to
pay the rent and other sums due thereunder directly to Landlord upon receiving
written notice from Landlord that Tenant is in default under this Lease with
respect to the payment of Rent. In the event that, notwithstanding the giving of
such notice, Tenant collects any rent or other sums from the assignee or
subtenant, then Tenant shall hold such sums in trust for the benefit of Landlord
and shall immediately forward the same to Landlord. Landlord's collection of
such rent and other sums shall not constitute an acceptance by Landlord of
attornment by such assignee or subtenant. A consent to one assignment,
subletting, occupation or use shall not be deemed to be a consent to any other
or

                                      14
<PAGE>

subsequent assignment, subletting, occupation or use, and consent to any
assignment or subletting shall in no way relieve Tenant of any liability under
this Lease. Any assignment or subletting without Landlord's consent shall be
void, and shall, at the option of Landlord, constitute a default under this
Lease.

          12.3.2   If Landlord approves an assignment of the entirety of
Tenant's interest in the Lease (as opposed to a subletting) as herein provided,
and provided Landlord's approval is accompanied by an instrument by which
Landlord releases Tenant from Tenant's obligations under this Lease which first
accrue from and after the date of assignment, then Tenant shall pay to Landlord,
as Additional Rent, one hundred percent (100%) of the excess, if any, of (1) the
rent, additional rent and any other consideration payable by the assignee to
Tenant, less reasonable and customary market-based leasing commissions, if any,
incurred by Tenant in connection with such assignment; minus (2) Base Rent plus
Additional Rent allocable to that part of the Premises affected by such
assignment or sublease pursuant to the provisions of this Lease, which
commissions shall, for purposes of the aforesaid calculation, be amortized on a
straight-line basis over the term of such assignment or sublease.

     Section 12.4   General Conditions.

          12.4.1   Except as may be to the contrary as provided for in Section
12.3.2, notwithstanding any assignment or subletting, Tenant and any guarantor
or surety of Tenant's obligations under this Lease shall at all times remain
fully and primarily responsible and liable for the payment of the Rent and for
compliance with all of Tenant's other obligations under this Lease (regardless
of whether Landlord's approval has been obtained for any such assignment or
subletting); provided, however, (X) in the event Landlord has made the election
to terminate pursuant to clause (1) of Section 12.1, Tenant shall be released
from its obligations hereunder to the extent the Lease has been terminated and
(Y) in the event Landlord has made the election to sublease or take an
assignment pursuant to clause (2) of Section 12.1, Tenant shall be released of
its obligations to the extent Landlord has taken an assignment of a portion of
the lease, or having taken a sublease, Landlord fails to perform its obligations
under such sublease.

          12.4.2   Tenant shall pay Landlord's reasonable fees (including,
without limitation, the fees of Landlord's counsel), incurred in connection with
Landlord's review and processing of documents regarding any proposed assignment
or sublease.

          12.4.3   Notwithstanding anything in this Lease to the contrary, in
the event Landlord consents to an assignment or subletting by Tenant in
accordance with the terms of this Section 12, Tenant's assignee or subtenant
shall have no right to further assign this Lease or any interest therein or
thereunder or to further sublease all or any portion of the Premises.  In
furtherance of the foregoing, Tenant acknowledges and agrees on behalf of itself
and any assignee or subtenant claiming under it (and any such assignee or
subtenant by accepting such assignment or sublease shall be deemed to
acknowledge and agree) that no sub-subleases or further assignments of this
Lease shall be permitted at any time.

          12.4.4   If this Lease is assigned, whether or not in violation of the
provisions of this Lease, Landlord may collect Rent from the assignee. If the
Premises or any part thereof is sublet or used or occupied by anyone other than
Tenant, whether or not in violation of this Lease, Landlord may, after a default
by Tenant, collect Rent from the subtenant or occupant. In either event,
Landlord may apply the net amount collected to Rent, but no such assignment,
subletting, occupancy or collection shall be deemed a waiver of any of the
provisions of this Section 12, or the acceptance of the assignee, subtenant or
occupant as tenant, or a release of Tenant from the further performance by
Tenant of Tenant's obligations under this Lease. The consent by Landlord to an
assignment, mortgaging, pledging, encumbering, transfer, use, occupancy or
subletting pursuant to any provision of this Lease shall not, except as
otherwise provided herein, in any way be considered to relieve Tenant from
obtaining the express consent of Landlord to any other or further assignment,
mortgaging, pledging, encumbering, transfer, use, occupancy or subletting.
References in this Lease to use or occupancy by anyone other than Tenant shall
not be construed as limited to subtenants and those claiming under or through

                                      15
<PAGE>

subtenants but as including also licensees or others claiming under or through
Tenant, immediately or remotely.  The listing of any name other than that of
Tenant on any door of the Premises or on any directory or in any elevator in the
Building, or otherwise, shall not, except as otherwise provided herein, operate
to vest in the person so named any right or interest in this Lease or in the
Premises, or be deemed to constitute, or serve as a substitute for, or any
waiver of, any prior consent of Landlord required under this Section 12.

          12.4.5   Each subletting and/or assignment pursuant to this Section 12
shall be subject to all of the covenants, agreements, terms, provision and
conditions contained in this Lease and each of the covenants, agreements, terms,
provisions and conditions of this Lease shall be automatically incorporated
therein. If Landlord shall consent to, or reasonably withhold its consent to,
any proposed assignment or sublease, Tenant shall indemnify, defend and hold
harmless Landlord against and from any and all loss, liability, damages, costs
and expenses (including reasonable counsel fees) resulting from any claims that
may be made against Landlord by the proposed assignee or sublessee or by any
brokers or other persons claiming a commission or similar in connection with the
proposed assignment or sublease.

                     ARTICLE 13.  SURRENDER OF POSSESSION

     Section 13.1   Surrender.   Upon the Termination Date, or upon the earlier
termination of this Lease as provided for herein, whether by lapse of time or
otherwise, Tenant shall surrender the Premises to Landlord.

     Section 13.2   Condition at Time of Surrender.   Furnishings, trade
fixtures and equipment including but not limited to voice and data cabling,
telecommunications equipment installed by Tenant shall be the property of
Tenant. Upon termination of this Lease, Tenant shall remove any such property.
Tenant shall repair any damage to the Premises and/or Common Areas resulting
from the installation or removal of Tenant's property, and Tenant shall deliver
the Premises to Landlord in clean and good condition, except for reasonable wear
and tear.

                           ARTICLE 14.  HOLDING OVER

     Section 14.1   Holding Over.   This Lease shall terminate without further
notice at the expiration of the Term.  Any holding over by Tenant without the
express written consent of Landlord shall not constitute the renewal or
extension of this Lease or give Tenant any rights in or to the Premises.  In the
event of such a holding over by Tenant without the express written consent of
Landlord, the monthly Rent payments to be paid by Tenant shall be subject to
increase at the sole discretion of Landlord in an amount equal to two hundred
percent (200%) of the then applicable Rental rate; provided, however, no payment
of such increased Rental by Tenant shall be deemed to extend or renew the Term
of this Lease, and such Rental payments shall be fixed by Landlord only to
establish the amount of liability for payment of Rent on the part of Tenant
during such period of holding over.  In the event Landlord shall give its
express written consent to Tenant to occupy the Premises beyond the expiration
of the Term, that occupancy shall be construed to be a month-to-month tenancy
upon all the same terms and conditions as set forth herein unless modified by
Landlord in such written consent; provided that Rent charged during any period
of holding over shall be as stated above.

                        ARTICLE 15.  ENTRY BY LANDLORD

     Section 15.1   Entry by Landlord.   Landlord reserves, and shall at any and
all times have, the right to enter the Premises during business hours to inspect
the same, to show the Premises to prospective purchasers or lessees, to post
notices of nonresponsibility, to repair the Premises and any portion of the
Building that Landlord may deem necessary or desirable, without abatement of
Rent, and may for that purpose erect scaffolding and other necessary structures
where reasonably required by the character of the work to be performed;
provided, that the entrance to the Premises shall not be blocked unreasonably
thereby and, provided, further that the business of the Tenant shall not be
interfered with unreasonably. Tenant hereby waives any claim for damages, injury
or inconvenience to or interference

                                      16
<PAGE>

with Tenant's business, any loss of occupancy or quiet enjoyment of the
Premises, and any other loss occasioned by Landlord's exercise of its rights
pursuant to this Section 15.1, except and to the extent any such damage, injury
or interference results from the negligence of Landlord. Landlord shall at all
times have and retain a key with which to unlock all of the doors in, upon and
about the Premises, excluding Tenant's vaults, safes and files, and Landlord
shall have the right to use any and all means which Landlord may deem proper to
open the doors to or in the Premises in an emergency, in order to obtain entry
to the Premises without liability to Tenant. Any entry to the Premises obtained
by Landlord by any of these means, or otherwise, shall not under any
circumstances be construed or deemed to be a forcible or unlawful entry into, or
a detainer of, the Premises, or an eviction of Tenant from the Premises or any
portion thereof.

     Section 15.2   Failure to Surrender.   If Tenant fails to surrender the
Premises upon the expiration of the Term or upon the sooner termination of this
Lease, Tenant shall indemnify and hold Landlord harmless from loss and liability
resulting from that failure, including, without limiting the generality of the
foregoing, any claims made by any succeeding tenant.

                          ARTICLE 16.  SUBORDINATION

     Section 16.1   Lease Subordinate To Mortgages.   This Lease shall
automatically be subordinate to any existing mortgages or deeds of trust which
affect the Property, the Building and/or the Premises; to any first mortgages or
deeds of trust hereafter affecting the Property, the Building and/or the
Premises, and to all renewals, modifications, consolidations, replacements or
extensions thereof. This provision shall be self-operative and no further
instrument of subordination shall be required by any existing or first mortgagee
or beneficiary of a deed of trust; provided, that Tenant shall have the
continued enjoyment of the Premises free from any disturbance or interruption by
any existing or first mortgagee or beneficiary of a deed of trust, or any
purchaser at a foreclosure or private sale of the Property as a result of
Landlord's default under a mortgage or deed of trust, so long as Tenant is not
then in default under the terms and conditions of this Lease. In the event of
the foreclosure of a deed of trust or mortgage affecting the Property,
judicially or nonjudicially, or if title to the Property is conveyed by deed in
lieu of foreclosure, Tenant agrees to attorn to and accept the purchaser(s) at
the foreclosure sale(s) conducted pursuant to the deed of trust or mortgage or
the grantee(s) in such deed(s) in lieu of foreclosure and his or its (or their)
heirs, legal representatives, successors and assigns as Landlord under this
Lease for the balance then remaining of the term hereof, subject to all terms
and conditions of this Lease.

     Section 16.2   Estoppel Certificates.   Tenant shall, within fifteen (15)
days of presentation, acknowledge and deliver to Landlord (a) any subordination
or non-disturbance agreement or other instrument that Landlord may require to
carry out the provisions of this Article, and (b) any estoppel certificate
requested by Landlord from time to time in the standard form of any mortgagee or
beneficiary of and deed of trust affecting the Building and Premises certifying,
if such be true, that Tenant is in occupancy, that this Lease is unmodified and
in full force and effect, or if there have been modifications, that the Lease as
modified is in full force and effect, and stating the modifications and the
dates to which the Rent and other charges shall have been paid, and that there
are no Rental offsets or claims.  Acceptable forms of estoppel certificate and
subordination agreement are attached as Exhibits F and G.

                        ARTICLE 17.  DEFAULT AND REMEDY

     Section 17.1   Events of Tenant's Default.   The occurrence of any one or
more of the following events shall constitute a material default and breach of
this Lease by Tenant:

          17.1.1   Vacation or abandonment of the Premises;

          17.1.2   Failure by Tenant to make any payment required as and when
due, where that failure shall continue for a period of eight (8) calendar days;

          17.1.3   Failure of Tenant to deposit with Landlord an amount equal to
the proceeds of any Letter of Credit or cash proceeds deposited with Landlord
pursuant to Paragraph 7 of

                                      17
<PAGE>

Exhibit E to this Lease which have been applied or retained by Landlord to
satisfy any obligation of Tenant under this Lease, within ten (10) calendar days
after Landlord's written demand to Tenant to do so;

          17.1.4   Failure of Tenant to deposit with Landlord a substitute
letter of credit in the Stipulated Amount on or before the LC Increase Date
pursuant to Paragraph 7.5 of Exhibit E to this Lease;

          17.1.5   Failure by Tenant to observe or perform any of the covenants,
conditions or provisions of this Lease, other than making any payment when due,
where that failure shall continue for a period of ten (10) calendar days after
Landlord gives written notice to Tenant of that failure; and

          17.1.6   Making by Tenant of any general assignment or general
arrangement for the benefit of creditors; the filing by or against Tenant of a
petition in bankruptcy, including reorganization or arrangement, unless, in the
case of a petition filed against Tenant, the petition is dismissed within ninety
(90) calendar days; or the appointment of a trustee or receiver to take
possession of substantially all of Tenant's assets located at the Premises, or
of Tenant's interest in this Lease.

     Section 17.2   Remedies.   In the event of any breach or default by Tenant
under the terms or provisions of this Lease, Landlord, in addition to any other
rights or remedies that it may have, shall have the immediate right of reentry.
Should Landlord elect to reenter or take possession of the Premises, it may
either terminate this Lease, or from time to time, without terminating this
Lease, relet the Premises or any part thereof for the account and in the name of
the Tenant or otherwise, for any term or terms and conditions as Landlord in its
sole discretion may deem advisable, with the right to complete construction of
or make alterations and repairs to the Premises and/or improvements installed by
Tenant.  Tenant shall pay to Landlord in the event of reletting, as soon as
ascertained, the costs and expenses incurred by Landlord in the reletting,
completion of construction, or in making any alterations and repairs.  Rentals
received by Landlord from any reletting shall be applied:  first, to the payment
of any indebtedness, other than Rent, due hereunder from Tenant to Landlord;
second, to the payment of Rent due and unpaid hereunder and to any other
payments required to be made by the Tenant hereunder; and the residue, if any,
shall be held by Landlord as payment of future Rent or damages in the event of
termination as the same may become due and payable hereunder; and the balance,
if any, at the end of the Term of this Lease shall be paid to Tenant.  Should
rental received from time to time from the reletting during any month be a
lesser Rental than herein agreed to by Tenant, the Tenant shall pay the
deficiency to Landlord.  The Tenant shall pay the deficiency each month as the
amount thereof is ascertained by the Landlord.  Notwithstanding the foregoing,
Landlord shall also have the right upon Tenant's default to terminate this Lease
and all rights of Tenant hereunder by giving written notice of such intention to
terminate.  In the event that Landlord shall elect to so terminate this Lease
then Landlord may recover from Tenant:

          17.2.1   The worth at the time of award of any unpaid Rent and any
other sums due and payable which have been earned at the time of such
termination; plus

          17.2.2   The worth at the time of award of the amount by which the
unpaid Rent and any other sums due and payable which would have been earned
after termination until the time of award exceeds the amount of such rental loss
Tenant proves could have been reasonably avoided; plus

          17.2.3   The worth at the time of award of the amount by which the
unpaid Rent and any other sums due and payable for the balance of the term of
this Lease after the time of award exceeds the amount of such rental loss that
Tenant proves could be reasonably avoided; plus

          17.2.4   Any other amount necessary to compensate Landlord for all the
detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which in the ordinary course would be likely to result
therefrom, including, without limitation, (A) any costs or expenses incurred by
Landlord (1) in retaking possession of the Premises; (2) in maintaining,
repairing,

                                      18
<PAGE>

preserving, restoring, replacing, cleaning, altering, remodeling or
rehabilitating the Premises or any affected portions of the Building or the
Project, including such actions undertaken in connection with the reletting or
attempted reletting of the Premises to a new tenant or tenants; (3) for leasing
commissions, advertising costs and other expenses of reletting the Premises; or
(4) in carrying the Premises, including taxes, insurance premiums, utilities and
security precautions; (B) any unearned brokerage commissions paid in connection
with this Lease; (C) reimbursement of any previously waived or abated Base Rent
or Additional Rent or any free rent or reduced rental rate granted hereunder;
and (D) any concession made or paid by Landlord to the benefit of Tenant in
consideration of this Lease including, but not limited to, any moving
allowances, contributions, payments or loans by Landlord for tenant improvements
or build-out allowances (including without limitation, any unamortized portion
of the improvement allowance provided to Tenant pursuant to Exhibit C, such
improvement allowance to be amortized over the Term in the manner reasonably
determined by Landlord), or assumptions by Landlord of any of Tenant's previous
lease obligations; plus

          17.2.5   Such reasonable attorneys' fees incurred by Landlord as a
result of a default, and costs in the event suit is filed by Landlord to enforce
such remedy; and plus

          17.2.6   At Landlord's election, such other amounts in addition to or
in lieu of the foregoing as may be permitted from time to time by applicable
law.

          17.2.7   As used in subparagraphs 17.2.1 and 17.2.2 above, the "worth
at the time of award" is computed by allowing interest at an annual rate equal
to twelve percent (12%) per annum or the maximum rate permitted by law,
whichever is less.  As used in subparagraph 17.2.3 above, the "worth at the time
of award" is computed by discounting such amount at the discount rate of Federal
Reserve Bank of San Francisco at the time of award, plus one percent (1%).
Tenant hereby waives for Tenant and for all those claiming under Tenant all
right now or hereafter existing to redeem by order or judgment of any court or
by any legal process or writ, Tenant's right of occupancy of the Premises after
any termination of this Lease.

     Section 17.3   Reletting.   No reletting of the Premises by Landlord
permitted under Section 17.2 shall be construed as an election on Landlord's
part to terminate this Lease unless a notice of Landlord's intention to
terminate is given to Tenant, or unless the termination of the Lease is decreed
by a court of competent jurisdiction. In the event of reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
for a previous breach, provided it has not been cured. Should Landlord at any
time terminate this Lease for any breach, in addition to any other remedy it may
have, it may recover from Tenant all damages it may incur by reason of that
breach.

     Section 17.4   Default of Landlord.   Landlord shall not be in default
unless Landlord fails to perform its obligations under this Lease within thirty
(30) days after written notice by Tenant, or if such failure is not reasonably
capable of being cured within such thirty (30) day period, Landlord shall not be
in default unless Landlord has failed to commence the cure and diligently pursue
the cure to completion.

     Section 17.5   Non-Waiver.   Failure by Landlord to take action or declare
a default as a result of any breach of any term, covenant or condition herein
contained shall not be deemed to be a waiver of that term, covenant, or
condition, or of any subsequent breach of any term, covenant or condition herein
contained. The subsequent acceptance of Rent hereunder by Landlord shall not be
deemed to be a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, other than the failure of Tenant to pay the particular
Rental so accepted, regardless of Landlord's knowledge of that preceding breach
at the time of acceptance of the Rent.

     Section 17.6   Mortgagee Protection.   In the event of any uncured default
on the part of Landlord, which default would entitle Tenant to terminate this
Lease, Tenant shall not terminate this Lease unless Tenant has notified any
mortgagee or beneficiary of deed of trust, whose address shall have been
furnished to Tenant, at least thirty (30) days in advance of the proposed
effective date of the termination.  During the thirty (30) day period the
mortgagee or beneficiary shall be entitled to commence

                                      19
<PAGE>

to cure the default. If the default is not capable of being cured with due
diligence within the thirty (30) day period, the Lease shall not be terminated
if the mortgagee or beneficiary of a deed of trust shall have commenced to cure
the default within the thirty (30) day period and shall pursue the cure with due
diligence thereafter. If the default is one which is not capable of cure by the
mortgagee or beneficiary of a deed of trust within the thirty (30) day period
because the mortgagee or beneficiary of a deed of trust is not in possession of
the Building or Property, the thirty (30) day period shall be extended to
include the time needed to obtain possession of the Premises by the mortgagee or
beneficiary of a deed of trust by power of sale, judicial foreclosure, or other
legal action required to recover possession, provided that these avenues are
pursued with due diligence.

                     ARTICLE 18.  LIMITATION OF LIABILITY

     Section 18.1   Limitation of Landlord's Liability.   Tenant understands,
covenants and agrees that the obligations of Landlord under this Lease shall not
constitute personal obligations of Landlord, the individual partners of Landlord
or its or their individual partners, directors, officers or shareholders, and
Tenant shall look solely to the Property and the Building, and to no other
assets of Landlord, for the satisfaction of any liability of Landlord with
respect to this Lease, and shall not seek recourse against the individual
partners of Landlord, or its or their individual partners, directors, officers
or shareholders, or any of their personal assets for such satisfaction.

     Section 18.2   Applicability.   Tenant agrees that each of the covenants
and agreements contained in Section 18.1 above shall be applicable to any
covenant or agreement either expressly contained in this Lease or imposed by
statute or at common law.

                             ARTICLE 19.  NOTICES

     Section 19.1   Notices.   Any notice required or desired to be given under
this Lease shall be in writing with copies directed as indicated herein and

deemed to have been given when seventy-two (72) hours have elapsed from the time
such notice was deposited in the United States mail, certified mail, return
receipt requested, and postage prepaid, addressed to the party to be served at
the last address given by that party to the other party under the provisions of
this section.  As of the Lease Commencement Date, the addresses of the Landlord
and Tenant are as specified in the Lease Summary.

                       ARTICLE 20.  HAZARDOUS SUBSTANCES

     Section 20.1   Presence and Use of Hazardous Substances.   Tenant shall
not, without Landlord's prior written consent, keep on or around the Premises,
Common Areas or Building, for use, disposal, transportation, treatment,
generation, storage or sale, any substances designated as, or containing
components designated as, hazardous, dangerous, toxic or harmful (collectively
referred to as "Hazardous Substances"), and/or are subject to regulation by any
federal, state or local law, regulation, statute or ordinance.

     Section 20.2   Landlord Indemnification.   Landlord shall indemnify,
defend, reimburse and hold Tenant harmless from and against any and all
environmental damages, including the cost of remediation, which existed as a
result of Hazardous Substances on the Premises prior to the Lease Commencement
Date or which are caused by the gross negligence or willful misconduct of
Landlord, its agents or employees.

     Section 20.3   Cleanup Costs, Default and Indemnification.   Tenant shall
be fully and completely liable to Landlord for any and all cleanup costs and any
and all other charges, fees, penalties (civil and criminal) imposed by any
governmental authority with respect to Tenant's use, disposal, transportation,
treatment, generation, storage and/or sale of Hazardous Substances, in or about
the Premises, Common Areas, or Building, whether or not consented to by
Landlord.  Tenant shall indemnify, defend and hold Landlord harmless from any
and all of the costs, fees, penalties, liabilities and charges incurred by,
assessed against or imposed upon Landlord (as well as Landlord's attorneys' fees
and costs)

                                      20

as a result of Tenant's use, disposal, transportation, treatment, generation,
storage and/or sale of Hazardous Substances.

                          ARTICLE 21.  MISCELLANEOUS

     Section 21.1   Headings.   The headings used in this Lease are for

     Section 21.5   Language.   The words "Landlord" and "Tenant", when used
herein, shall be applicable to one (1) or more persons, as the case may be, and
the singular shall include the plural and the neuter shall include the masculine
and feminine, and if there be more than one (1) the obligations hereof shall be
joint and several.  The word "persons" whenever used shall include individuals,
firms, associations and corporations and any other legal entity, as applicable.
The language in all parts of this Lease shall in all cases be construed as a
whole and in accordance with its fair meaning, and shall not be construed

     Section 21.6   Invalidity.   If any provision of this Lease shall be deemed
to be invalid, void or illegal, it shall in no way affect, impair or invalidate
any other provision hereof.

     Section 21.7   Late Charges.   Tenant hereby acknowledges that late payment
by Tenant to Landlord of Rent or other sums due hereunder will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which is
difficult to determine, but include, without limitation, processing and
accounting charges, and late charges which may be imposed upon Landlord by the
terms of any mortgage or deed of trust covering the Premises.  Therefore, in the
event Tenant shall fail to pay any installment of Rent or other sum due
hereunder within ten (10) days of the due date, Tenant shall pay to Landlord as
Additional Rent and as a reasonable estimate of the costs to Landlord, a late
charge equal to ten percent (10%) of each installment or the sum of One Hundred
Fifty Dollars ($150.00) per month, whichever is greater.  A One Hundred Fifty
Dollar ($150.00) charge will be paid by the Tenant to the Landlord for each
returned check.  In the event Landlord pays any sum or expense on behalf of
Tenant which Tenant is obligated to pay hereunder, or in the event Landlord
expends any other sum or incurs any expense, or Tenant fails to pay any sum due
hereunder, Landlord shall be entitled to receive interest upon that sum at the
rate of fifteen percent (15%) per annum until paid.
