                                    RECITALS

         A. As of May 28, 1999, the Company entered into a 1999 Amended and

         C. As of August 3, 1999, Medscape entered into a Registration Rights
Agreement (the "CBS Agreement") with CBS Corporation ("CBS") that provided
certain registration rights to CBS with respect to Medscape common stock owned
by CBS.

         D. As of August 25, 1999 and September 8, 1999, the 1999 Medscape

to MedicaLogic/Medscape, Inc.

         F. In Section 1.9 of the Merger Agreement, the Company and Medscape
agreed that any registration rights existing as of the date of the Merger
Agreement with respect to Medscape common stock would, as of the effective date
of the Merger, be converted into the same rights with respect to Company common
stock received in exchange therefor pursuant to the Merger, and that they would
execute such documents and take such further actions as may be necessary or
desirable to effectuate the provisions of Section 1.9.

         G. Section 3.7 of the 1999 MedicaLogic Agreement provides that the 1999

outstanding.

                  1.2 REQUEST FOR REGISTRATION.

<PAGE>

                           (a) If (i) the Company shall receive, at any time
after December 31, 1999, a written request from (A) Holders of at least fifteen
percent (15%) of the Registrable Securities then outstanding referred to in
clauses (i) and (ii) of subsection 1.1(g) or (B) Holders of at least thirty
percent (30%) of the Registrable Securities then outstanding held by the former
holders of the Company's Series J Preferred Stock (a "Series J Investor") that
the Company file a registration statement under the Act covering the
registration of the Registrable Securities then outstanding, or (ii) the Company
shall receive a written request from (W) Holders of at least fifty percent (50%)
of the Registrable Securities then outstanding held by the former holders of
Investor Registrable Securities (excluding Holders described in clause (X), (Y)
or (Z) hereof) as listed on Signature Page C hereto, (X) any Holder who
purchased more than 650,000 shares of the Series D Preferred Stock of Medscape
as listed on Signature Page D hereto (a "Series D Holder"), (Y) any Holder who
purchased more than 260,000 shares of the Series E Preferred Stock of Medscape
as listed on Signature Page E hereto (a "Series E Holder"), or (Z) any Holder of
Warrant Shares, that the Company file a registration statement on Form S-1 (or
similar successor forms) under the Act covering the registration of Registrable
Securities issued in exchange for Investor Registrable Securities, then the
Company shall, within ten (10) days of the receipt thereof, give written notice
of such request to all Holders and shall, subject to the limitations of
subsection 1.2(b), use its reasonable best efforts to effect as soon as
practicable, and in any event within one hundred twenty (120) days of the
receipt of such request, the registration under the Act of all Registrable
Securities that the Holders request to be registered within twenty (20) days of
the mailing of such notice by the Company in accordance with Section 3.5,
provided that the Registrable Securities requested by the Holders to be
registered pursuant to such request must have an anticipated aggregate public
offering price of not less than $5,000,000.

                           (b) If the Holders initiating the registration
request hereunder ("Initiating Holders") intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to subsection 1.2(a)
and the Company shall include such information in the written notice referred to
in subsection 1.2(a). The underwriter will be selected by the Initiating Holders
and shall be reasonably acceptable to the Company, provided that such
underwriter shall be of nationally recognized standing and shall agree to firmly
underwrite such offering. In such event, the right of any Holder to include
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Company as provided in subsection
1.4(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provisions of this Section 1.2, if the underwriter, with respect to a
registration requested under subsection 1.2(a)(i), advises the Initiating
Holders in writing that marketing factors require a limitation

<PAGE>

of the number of shares to be underwritten, then such Initiating Holders shall
so advise all Holders of Registrable Securities which would otherwise be
underwritten pursuant hereto, and the number of shares of Registrable Securities
that may be included in the underwriting shall be allocated among all Holders
thereof, including such Initiating Holders, in proportion (as nearly as
practicable) to the amount of Registrable Securities of the Company owned by
each Holder; provided, however, that the number of shares of Registrable
Securities to be included in such underwriting shall not be reduced unless all
other securities are first entirely excluded from the underwriting; and
provided, further, that Registrable Securities held by Holders referred to in
subsection 1.2(a)(ii) shall be entirely excluded from the underwriting before
any Registrable Securities held by Holders referred to in subsection 1.2(a)(i)
are excluded. In a registration pursuant to subsection 1.2(a)(i), if Registrable
Securities held by a Series J Investor are excluded from the registration
pursuant to the previous sentence as a result of election of Holders other than
Series J Investors to participate in the registration, then that registration
will not be deemed to be a registration requested by the Series J Investors for
the purposes of Section 1.2(d)(i).

                           (c) Notwithstanding the foregoing, if the Company
shall furnish to Holders requesting a registration statement pursuant to this
Section 1.2, a certificate signed by the Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its shareholders
for such registration statement to be filed and it is therefore essential to
defer the filing of such registration statement, the Company shall have the
right to defer taking action with respect to such filing for a period of not
more than ninety (90) days after receipt of the request of the Initiating
Holders; provided, however, that the Company may not utilize this right more
than once in any twelve-month period.

                           (d) In addition, the Company shall not be obligated
to effect, or to take any action to effect,

                                    (i) any registration pursuant to subsection
1.2(a)(i):

                                             (A) After the Company has effected
         three (3) registrations pursuant to subsection 1.2(a)(i), two (2) of
         which may only be initiated by Series J Investors under subsection
         1.2(a)(i)(B), and such registrations have been declared or ordered
         effective; or

                                             (B) During the period starting with
         the date sixty (60) days prior to the Company's good faith estimate of
         the date of filing of, and ending on a date sixty (60) days after the
         effective date of, a registration subject to Section 1.3 hereof,
         provided that the Company is actively employing in good faith all
         reasonable efforts to cause such registration statement to become
         effective; or

                                    (ii) any registration pursuant to subsection
1.2(a)(ii):

<PAGE>

                                             (A) After the Company has effected
         seven (7) registrations pursuant to subsection 1.2(a)(ii), two (2) of
         which may only be initiated by a Series D Holder, one (1) of which may
         only be initiated by a Series E Holder, two (2) of which may only be
         initiated by a Holder of Warrant Shares, and two (2) of which may only
         be initiated by Holders who are not Series D Holders, Series E Holders
         or Holders of Warrant Shares; or

                                             (B) During the period starting with
         the date sixty (60) days prior to the Company's good faith estimate of
         the date of filing of, and ending on a date one hundred eighty (180)
         days after the effective date of, a registration subject to Section 1.3
         hereof, provided that the Company is actively employing in good faith
         all reasonable efforts to cause such registration statement to become
         effective; or

                                             (C) If the Initiating Holders
         propose to dispose of shares of Registrable Securities which may be
         immediately registered on Form S-3 pursuant to a request made under
         Section 1.12 hereof.

                  1.3 COMPANY REGISTRATION. If (but without any obligation to do
so) the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
stock or other securities under the Act in connection with the public offering
of such securities solely for cash (other than a registration relating solely to
the sale of securities to participants in a Company stock plan, a registration
on any form which does not include substantially the same information as would
be required to be included in a registration statement covering the sale of the
Registrable Securities or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered), the Company shall, at such time, promptly, but at least
thirty (30) days prior to filing such registration statement, give each Holder
written notice of such registration. Upon the written request of each Holder
given within twenty (20) days after receipt of such notice by the Holder in
accordance with Section 3.5, the Company shall, subject to the provisions of
Section 1.8, cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

                  1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this
Section 1 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                           (a) Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its diligent
efforts to cause such registration statement to become effective, and, upon the
request of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for a period of up to one
hundred eighty (180) days; provided, however, that (i) such 180-day

<PAGE>

period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;
and (ii) in the case of any registration of Registrable Securities on Form S-3
which are intended to be offered on a continuous or delayed basis, such 180-day
period shall be extended, if necessary, to keep the registration statement
effective until all such Registrable Securities are sold, provided that Rule
415, or any successor rule under the Act, permits an offering on a continuous or
delayed basis; and provided further that applicable rules under the Act
governing the obligation to file a post-effective amendment permit, in lieu of
filing a post-effective amendment which (I) includes any prospectus required by
Section 10(a)(3) of the Act or (II) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (I) and (II) above to be contained in periodic reports filed pursuant to
Section 13 or 15(d) of the 1934 Act in the registration statement.

                           (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

                           (c) Furnish to the Holders such numbers of copies of
a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                           (d) Use its reasonable best efforts to register and
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders; provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such
jurisdiction and except as may be required by the Act.

                           (e) In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                           (f) Notify each Holder of Registrable Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to

<PAGE>

make the statements therein not misleading in the light of the circumstances
then existing.

                           (g) Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed.

                           (h) Provide a transfer agent and registrar for all
Registrable Securities registered pursuant hereunder and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration.

                           (i) Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Section 1, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Section 1, if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters, on the date that the registration statement with respect
to such securities becomes effective, (i) an opinion, dated such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

                  1.5 FURNISH INFORMATION. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to this Section 1
with respect to the Registrable Securities of any selling Holder that such
Holder shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Holder's
Registrable Securities.

                  1.6 EXPENSES OF DEMAND REGISTRATION. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2 (which right
may be assigned as provided in Section 1.13), including (without limitation) all
registration, filing, qualification, printers' and accounting fees, fees and
disbursements of counsel for the Company (including fees and disbursements of
counsel for the Company in its capacity as counsel to the selling Holders
hereunder; if Company counsel does not make itself available for this purpose,
the Company will pay the reasonable fees and disbursements of one counsel for
the selling Holders) shall be borne by the Company; provided, however, that the
Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Section 1.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all participating

<PAGE>

Holders shall bear such expenses), unless the Holders of a majority of the
Registrable Securities agree to forfeit the applicable demand registration right
pursuant to Section 1.2; provided further, however, that if at the time of such
withdrawal, the Holders have learned of a material adverse change in the
condition, business, or prospects of the Company from that known to the Holders
at the time of their request and have withdrawn the request with reasonable
promptness following disclosure by the Company of such material adverse change,
then the Holders shall not be required to pay any of such expenses and shall
retain their rights pursuant to Section 1.2.

                  1.7 EXPENSES OF COMPANY REGISTRATION. The Company shall bear
and pay all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing,
qualification, printers' and accounting fees, fees and disbursements of counsel
for the Company (including fees and disbursements of counsel for the Company in
its capacity as counsel to the selling Holders hereunder; if Company counsel
does not make itself available for this purpose, the Company will pay the
reasonable fees and disbursements of one counsel for the selling Holders) but
excluding underwriting discounts and commissions relating to Registrable
Securities.

                  1.8 UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Holders of a majority of the Registrable Securities
that indicated they would like to be included in the underwriting, the Company
and the underwriters selected by it (or by other persons entitled to select the
underwriters), and then only in such quantity as the underwriters determine in
their sole discretion will not jeopardize the success of the offering by the
Company. If the total amount of securities, including Registrable Securities,
requested by shareholders to be included in such offering exceeds the amount of
securities sold other than by the Company that the underwriters determine in
their sole discretion is compatible with the success of the offering, then the
Company shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters determine
in their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling shareholders
according to the total amount of securities entitled to be included therein
owned by each selling shareholder or in such other proportions as shall mutually
be agreed to by such selling shareholders) but in no event shall (i) the amount
of securities of the selling Holders included in the offering be reduced below
thirty percent (30%) of the total amount of securities included in such
offering, or (ii) notwithstanding (i) above, Section 1.2 governs the exclusion
of shares being sold by a shareholder exercising a demand registration right
granted thereunder. For purposes of the preceding parenthetical concerning
apportionment, for any selling shareholder which is a holder of Registrable
Securities and which is a partnership or corporation, the partners,

<PAGE>

retired partners and shareholders of such holder, or the estates and family
members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons shall be deemed to be a single "selling
shareholder," and any pro-rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder," as defined in this sentence.

                  1.9 DELAY OF REGISTRATION. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

                  1.10 INDEMNIFICATION. In the event any Registrable Securities
are included in a registration statement under this Section 1:

                           (a) To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, any underwriter (as defined in the Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Act or the 1934 Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law, or
any rule or regulation promulgated under the Act, and the Company will pay to
each such Holder, underwriter or controlling person, as incurred, any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 1.10(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable in any such case for any such loss, claim, damage, liability, or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, underwriter or
controlling person.

                           (b) To the extent permitted by law, each selling
Holder will indemnify and hold harmless the Company, each of its directors, each
of its officers who has signed the registration statement, each person, if any,
who controls the Company within

<PAGE>

the meaning of the Act, any underwriter, any other Holder selling securities in
such registration statement and any controlling person or any such underwriter
or Holder, against any losses, claims, damages, or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Act, the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereto) arise out of or are
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 1.10(b), in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.10(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided, however, that in no event shall
any indemnity under this subsection 1.10(b) exceed the net proceeds from the
offering received by such Holder.

                           (c) Promptly after receipt by an indemnified party
under this Section 1.10 of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 1.10,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.10.

                           (d) If the indemnification provided for in this
Section 1.10 is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any loss, liability, claim, damage, or
expense referred to herein, then the indemnifying party, in lieu of indemnifying
such indemnified party hereunder, shall contribute to the amount paid or payable
by such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim,

<PAGE>

damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission. Notwithstanding
the foregoing, (i) no Holder shall be required to contribute any amount in
excess of the public offering price of all Registrable Securities offered and
sold by such Holder pursuant to such registration statement, and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.

                           (e) The obligations of the Company and Holders under
this Section 1.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

                  1.11 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a
view to making available to the Holders the benefits of Rule 144 promulgated
under the Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

                           (a) make and keep public information available, as
those terms are understood and defined in SEC Rule 144, at all times after
ninety (90) days after the effective date of the first registration statement
filed by the Company for the offering of its securities to the general public;

                           (b) take such action, including the voluntary
registration of its Common Stock under Section 12 of the 1934 Act, as is
necessary to enable the Holders to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the
end of the fiscal year in which the first registration statement filed by the
Company for the offering of its securities to the general public is declared
effective;

                           (c) file with the SEC in a timely manner all reports
and other documents required of the Company under the Act and the 1934 Act; and

                           (d) furnish to any Holder, so long as the Holder owns
any Registrable Securities, forthwith upon request (i) a written statement by
the Company that it has complied with the reporting requirements of SEC Rule 144
(at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company),

<PAGE>

the Act, and the 1934 Act (at any time after it has become subject to such
reporting requirements), or that it qualifies as a registrant whose securities
may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company, and (iii) such other information
as may be reasonably requested in availing any Holder of any rule or regulation
of the SEC which permits the selling of any such securities without registration
or pursuant to such form.

                  1.12 FORM S-3 REGISTRATION. In case the Company shall receive
from any Holder or Holders a written request or requests that the Company effect
a registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will:

                           (a) promptly give written notice of the proposed
registration, and any related qualification or compliance, to all other Holders;
and

                           (b) as soon as practicable, effect such registration
and all such qualifications and compliances as may be so requested and as would
permit or facilitate the sale and distribution of all or such portion of such
Holder's or Holders' Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any other
Holder or Holders joining in such request as are specified in a written request
given within twenty (20) days after receipt of such written notice from the
Company; provided, however, that the Company shall not be obligated to effect
any such registration, qualification or compliance, pursuant to this Section
1.12: (1) if Form S-3 is not available for offering by the Holders; (2) if the
Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at an aggregate price to the
public (net of any underwriters' discounts or commissions) of less than
$1,000,000; (3) if the Company shall furnish to the Holders a certificate signed
by the President of the Company stating that in the good faith judgment of the
Board of Directors of the Company, it would be seriously detrimental to the
Company and its shareholders for such Form S-3 Registration to be effected at
such time, in which event the Company shall have the right to defer the filing
of the Form S-3 registration statement for a period of not more than 150 days
after receipt of the request of the Holder or Holders under this Section 1.12;
provided, however, that the Company shall not utilize this right more than once
in any twelve (12) month period; (4) if the Company has, within the six (6)
month period preceding the date of such request, already effected one
registration on Form S-3 for the Holders pursuant to this Section 1.12; or (5)
in any particular jurisdiction in which the Company would be required to qualify
to do business or to execute a general consent to service of process in
effecting such registration, qualification or compliance.

                           (c) Subject to the foregoing, the Company shall file
a registration statement covering the Registrable Securities and other
securities so requested to be

<PAGE>

registered as soon as practicable after receipt of the request or requests of
the Holders. The Company shall bear and pay all expenses incurred in connection
with a registration requested pursuant to Section 1.12, including (without
limitation) all registration, filing, qualification, printer's and accounting
fees, fees and disbursements of counsel for the Company (including fees and
disbursements of counsel for the Company in its capacity as counsel to the
selling Holder or Holders hereunder, if Company counsel does not make itself
available for this purpose, the Company will pay the reasonable fees and
disbursements of one counsel for the selling Holder or Holders) but excluding
underwriting discounts and commissions relating to Registrable Securities;
provided, however, that the Company shall not be obligated to pay registration
expenses under this paragraph if the Company has already effected two
registrations on Form S-3 pursuant to this Section 1.12. Registrations effected
pursuant to this Section 1.12 shall not be counted as registrations effected
pursuant to Section 1.2 or 1.3.

                  1.13 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause
the Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities, provided: (a) the Company is, within a reasonable
time after such transfer, furnished with written notice of the name and address
of such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee acquires
from the Holder more than 100,000 shares; (c) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.15 below;
and (d) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.

                  1.14 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and
after the date of this Agreement, the Company shall not, without the prior
written consent of the Holders of a majority of the outstanding Registrable
Securities, enter into any agreement with any holder or prospective holder of
any securities of the Company which would allow such holder or prospective
holder (a) to include such securities in any registration filed under Section
1.2 hereof, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of such securities will not reduce the amount of the
Registrable Securities of the Holders which is included or (b) to make a demand
registration which could result in such registration statement being declared
effective prior to the earlier of either of the dates set forth in subsection
1.2(a) or within one hundred twenty (120) days of the effective date of any
registration effected pursuant to Section 1.2. If the Company grants
registration rights to holders of any security of the Company which are more
favorable to such holders than the registration rights granted hereunder, then
such more favorable registration rights shall also be deemed to be granted to
the Holders of Registrable Securities hereunder, and the Company covenants and
agrees to take any and all steps necessary to modify the terms of this Agreement
to so provide.

                  1.16 TERMINATION OF REGISTRATION RIGHTS.

                           (a) No Holder shall be entitled to exercise any right
provided for in this Section 1 after December 10, 2009.

                           (b) In addition, the right of any Holder to request
registration or inclusion in any registration pursuant to Section 1 shall
terminate on such date that all shares of Registrable Securities held or
entitled to be held upon conversion by such Holder may immediately be sold under
Rule 144 during any 90-day period; provided, however, that the provisions of
this Section 1.16(b) shall not apply to any Holder who owns at least one percent
(1%) of the Company's outstanding stock.

except as follows:

                           (a) any amendment or waiver affecting only the rights

two-thirds percent (66 2/3%) of such Registrable Securities; and

                           (d) any amendment or waiver affecting only the rights

future holder of such Registrable Securities and the Company.

                  3.8 SEVERABILITY. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, such provision shall be
excluded from this

<PAGE>

Agreement and the balance of the Agreement shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

                  3.9 AGGREGATION OF STOCK. All shares of Registrable Securities
(including the Common Stock issuable upon conversion thereof), as applicable,
held or acquired by a Holder shall be aggregated together for the purpose of
determining the availability of any rights under this Agreement.

                  3.10 ENTIRE AGREEMENT; AMENDMENT; WAIVER. This Agreement

validly existing and in good standing under the laws of the State of California.
Kaufman Trust is a revocable trust duly formed, validly existing and in good
standing under the laws of the State of California. Landlord has all requisite
legal power and authority to enter into this Lease and to perform its
obligations hereunder. The sole general partner of Kaufman Partnership is Ron
Kaufman ("RK"), and the sole trustees of Kaufman Trust are RK and Barbara Lynn
Kaufman. The execution, delivery and performance by Landlord under this Lease
have been duly authorized by the trustees of the Kaufman Trust and by the
partners in Kaufman Partnership, do not conflict with any agreement or
restriction binding upon Landlord, any trustee in Kaufman Trust, any general
partner in Kaufman Partnership or the Property. RK has full power and authority
to make and implement, on behalf of Landlord, all design, construction,
financing and operating decisions necessary to Landlord's full and timely
performance of its obligations under this Lease.

                  (b) To the best of Landlord's knowledge, the Property is zoned
M-1, and such zoning will accommodate Tenant's intended use of the Project;
however, all other land use entitlements for construction and development of the
Project for the use thereof contemplated by Tenant under this Lease must be
obtained from the appropriate governmental authorities, including, without

best of Landlord's knowledge, those entitlements may include, without
limitation, certification of an environmental impact report, a conditional use
permit or planned unit development authorization, and any other requirements or
conditions that may be imposed at the Planning Department staff or the Planning
Commission level. Further, the development of the Project is subject to the
discretionary review at a full hearing of the Planning Commission at the
discretion of the Planning Department staff or at the request of any interested
party. Site permits, addenda and/or building permits will need to be obtained
from the San Francisco Department of Building Inspection in order to authorize
construction of the Project. A variety of authorizations will likely be required
from the San Francisco Department of Public Works.

of the sixth year of the Term, and the denominator of which shall be the Index
figure published most recently prior to the Commencement Date. Notwithstanding
the foregoing, in no event shall the Base Rent as so adjusted be (i) greater

percent (110%), of the Base Rent for the first five years of the Term.

                  (c) The Base Rent payable by Tenant to Landlord for the

the sixth through tenth years of the Term multiplied by a fraction, the
numerator of which shall be the Index figure published most recently prior to
the first day of the eleventh year of the Term, and the denominator of which
shall be the Index figure published most recently prior to the first day of the
sixth year of the Term. Notwithstanding the foregoing, in no event shall the
Base Rent as so adjusted be (i) greater than one hundred thirty percent (130%),

numerator of which shall be the Index figure published most recently prior to
the first day of the sixteenth year of the Term, and the denominator of which
shall be the Index figure published most recently prior to the first day of the
eleventh year of the Term. Notwithstanding the foregoing, in no event shall the
Base Rent as so adjusted be (i) greater than one hundred thirty percent (130%),

immediately preceding the date of such adjustment.

the cost of living.

         5.2 TAXES. As used in this Lease, the term "Taxes" shall mean all AD
VALOREM taxes, assessments and charges levied upon or with respect to the
Premises, or Landlord's interest in the Premises, including all real property
taxes and general and special assessments; charges, fees, levies or assessments
for transit, housing, police, fire or other governmental services or purported
benefits to the Premises; service payments in lieu of taxes; excise taxes; gross
receipts taxes; commercial rent taxes; water and sewer taxes; any tax, fee or
excise on the act of entering into this Lease or on the use or occupancy of the

contemplation of the parties hereto, which may now or hereafter be levied or
assessed against Landlord by the United States of America, the State of
California, the City and County of San Francisco or any political subdivision,
public corporation, district or other political or public entity, and any other

hereinafter defined) occurring subsequent to the date of this Lease, other than
(i) the change in ownership resulting from Landlord's transfer of an undivided
one-half interest in the Premises to Tenant pursuant to the Option Agreement, or
(ii) any subsequent changes in ownership initiated by Tenant. For the purposes
of this Lease, "change in ownership" shall have the meaning provided in Sections
61 ET SEQ. of the California Revenue and Taxation Code, as amended or recodified
from time to time, and the regulations promulgated thereunder.

         5.4 ADDITIONAL TAXES. In addition to the Base Rent and other amounts
payable by Tenant hereunder, to the extent that Tenant shall not have paid any
such amounts directly to the appropriate party therefor, Tenant shall reimburse
Landlord for any and all taxes, surcharges, levies, assessments, fees and
charges paid by Landlord, whether or not now customary or within the
contemplation of the parties hereto upon, measured by or reasonably attributable
to the cost or value of Tenant's equipment, furniture, fixtures and other
personal property located in the Premises, or the cost or value of the Tenant
Improvements or any leasehold improvements or alterations, additions and
improvements to the Premises made by Tenant under Article 8 below, regardless of
whether title to such improvements shall be in Tenant or Landlord.

         5.5 CONTEST. Notwithstanding the provisions of Section 5.1 above,
Tenant shall not be required to pay any Taxes so long as Tenant contests in good
faith such Taxes or the validity, applicability or amount thereof, by an
appropriate legal proceeding which operates to prevent the collection of such
amounts and the sale of the Premises or any portion thereof by reason of such
contest; provided, however, that prior to the date on which such Taxes would
otherwise have become delinquent, Tenant shall have given to Landlord written
notice of such contest. Tenant shall prosecute any such contest with due
diligence, and Tenant shall promptly pay the amount of such Taxes finally
determined to be owing, together with all interest and penalties payable in
connection therewith. In addition, notwithstanding Tenant's right of contest,
Tenant shall cause any delinquent Taxes and penalties to be paid to the extent
reasonably required by Landlord in connection with Landlord's efforts to finance
or sell the Project.

                           (iv) The cost of capital items, including, without
                  limitation, capital improvements, capital replacements or
                  capital equipment, all as determined in accordance with
                  generally accepted accounting principles, consistently applied

                  to be borne by Tenant under the provisions of subparagraph (c)
                  below.

         If Tenant's performance of Tenant's repair, maintenance and/or
         replacement obligations under this Lease would cause Tenant to incur
         any of the foregoing costs and expenses, at Landlord's option, Landlord
         shall either be obligated to (A) perform promptly such repair,
         maintenance or replacement item, or (B) pay to Tenant the amount of
         such cost or expense within thirty (30) days following written notice
         thereof to Landlord of the actual amount thereof, together with
         reasonable documentation of such amount, and Tenant shall not be
         obligated to commence or perform such repair, maintenance or
         replacement item until Tenant shall have received such payment from
         Landlord. In the event of any disagreement between Landlord and Tenant
         as to the obligation to perform any such repair, maintenance or
         replacement item, or the cost or expense of performing such repair,
         maintenance or replacement item, Landlord and Tenant shall meet and
         confer and, acting reasonably and in good faith, attempt to resolve
         such disagreement within thirty (30) days. If Landlord or Tenant shall
         be unable to resolve such disagreement within thirty days, either party
         shall thereafter have the right to refer the matter to arbitration in
         accordance with the provisions of Section 20.24 of this Lease.

                  (c) Notwithstanding anything to the contrary contained in this
Article 6 or elsewhere in this Lease, the following costs and expenses of
Capital Items shall be allocated between Landlord and Tenant in the manner
provided for below:

                           (i) Costs of Capital Items constructed or installed
                  by Landlord or Tenant in or to the Premises as required by
                  this Lease in order to comply with applicable statutes,
                  ordinances, rules and regulations of governmental authorities
                  that were not in effect as of the Commencement Date; provided,
                  however, that the cost of Capital Items constructed or
                  installed by Landlord or Tenant in or to the Premises to
                  comply with Hazardous Materials Laws that were not in effect
                  as of the Commencement Date shall be allocated between
                  Landlord and Tenant as follows: Tenant shall be responsible
                  for the costs of such Capital Items constructed or installed
                  by Landlord or Tenant in or to the interior of the Premises,
                  and Landlord shall be responsible for the costs of such
                  Capital Items constructed or installed by Landlord or Tenant
                  in or to the Building Shell or the portion of the Premises
                  located outside of the Building Shell, including the
                  subsurface portions of the Premises. Notwithstanding the

                  foregoing, any such costs which are attributable to a
                  condition caused by Tenant shall be borne solely by Tenant;
                  and

                           (ii) Costs of Capital Items constructed or installed
                  by Landlord or Tenant in or to the Premises in order to
                  maintain the Premises in the condition required under this
                  Lease.

The costs and expenses of Capital Items described in this subparagraph (c) shall
be allocated between Landlord and Tenant as follows: (A) Landlord and Tenant
shall first reasonably determine the useful life of the Capital Item in
accordance with generally accepted accounting principles consistently applied;
(B) if the useful life of the Capital Item shall be less than the period of time
remaining in the Term (including any extensions of the Term agreed to by
Landlord and Tenant), Tenant shall bear the entire cost of such Capital Item;
(C) if the useful life of the Capital Item shall extend beyond the remaining
Term (including any extensions of the Term agreed to by Landlord and Tenant),
Tenant shall bear a portion of such cost equal to the product of such cost
multiplied by a fraction, the numerator of which shall be the number of months
remaining in the Term (including any extensions of the Term agreed to by
Landlord and Tenant), and the denominator of which shall be the number of months
contained in the useful life of such Capital Item; and (D) Landlord shall bear
the balance of the cost of such Capital Item. If Landlord and Tenant shall agree
to extend the Term, the cost of any such Capital Item shall be recalculated and
reallocated based upon the extended Term of this Lease. The party whose
obligations under this Lease require the construction or installation of any
such Capital Item shall be responsible for reasonably determining the cost of
constructing or installing such Capital Item (as determined by Section 6.3(b)
above) and for the timely performance of such work in accordance with this
Lease. Landlord and Tenant shall each be obligated to pay its allocable share of
the costs and expenses of such Capital Item into a segregated account maintained
by the party performing such work within thirty (30) days following written
notice of the cost of performing such work given by the party performing such
work to the other party, together with such reasonable detail of such cost as
the other party shall reasonably require. The party performing such work shall
apply the amounts in such account to the cost of construction or installation of
such Capital Item throughout the course of performance of such work. Neither
Landlord nor Tenant shall be obligated to commence the work of construction or
installation of any Capital Item unless and until the other party shall have
paid its allocable share of such costs and expenses as provided above. If
Landlord or Tenant shall fail to advance in a timely manner such party's
allocable share of such costs and expenses within the time period required
above, the other party shall have the right to advance such amount for the
account of the non-advancing party, and the non-advancing party shall be
obligated to repay such amount, together with interest thereon at the Interest
Rate (as defined below) from the date of such advance, upon demand by the

concerning the costs and expenses of the Capital Item or the allocation thereof
between Landlord and Tenant, Landlord and Tenant shall meet and confer and
attempt to resolve the disagreement in the manner provided for in Section 6.3(b)
above, and shall thereafter have the right to refer the matter to arbitration as
provided in such Section 6.3(b) above.

         6.4 INSPECTION. Landlord and Tenant shall each have the right
periodically to review the other party's books and records (which are to be
located in the City and County of San Francisco) pertaining to the costs and
expenses described in Section 6.3 above at any time during normal business hours
and after reasonable notice to the other party. Landlord and Tenant shall each
keep and maintain the results of any such review of the other party's books and
records privileged and confidential, and shall not disclose or disseminate any
information derived from any such review to any other person or entity without
the other party's prior written consent, except as may be required by applicable
law.

otherwise in connection with the commencement of utility and other services to

improvements to the Premises or any part thereof (except for telephone and
telecommunications equipment, cabling and furniture, fixtures, and equipment
which are not permanently attached to the Premises), which cost is in excess of
Two Hundred Fifty Thousand Dollars ($250,000), without Landlord's prior written
consent, which consent shall not be unreasonably withheld. Notwithstanding the
foregoing, without the prior written consent of Landlord, which consent shall
not be unreasonably withheld, Tenant shall have no right to make any
alterations, additions, or improvements to the Premises or any part thereof (a)
that affect the exterior appearance of the Building, or (b) would adversely

other related documents reasonably requested by Landlord together with the
request for such consent. If necessary, Landlord shall reasonably cooperate with
Tenant, at no cost to Landlord, to obtain any governmental permits, licenses or
approvals necessary to make any such alterations, additions or improvements.

as-built drawings of the alterations, additions or improvements. Tenant shall
cause any contractor performing the work of any such alterations, additions and
improvements to carry builder's risk and liability insurance in amounts and

action (including attorney's fees) arising out of Tenant's performance of any
work of alteration, addition or improvement in the Premises, including liens or
claims for work performed or materials furnished to or at the request of Tenant.
Tenant shall keep the Premises free from any liens arising out of any work
performed, materials furnished or obligations incurred by Tenant. Within thirty
(30) days following the date on which Tenant shall receive written notice from
Landlord or otherwise that any such lien has been recorded against the Premises,
Tenant shall either cause such lien to be satisfied or Tenant shall cause to be
recorded an appropriate lien release bond sufficient to cause such lien to be
removed as a lien on the Premises. Landlord shall have the right to post and
keep posted on the Premises any notices that may be provided by law or which
Landlord may deem to be proper for the protection of Landlord or the Premises
from such liens.

                             DAMAGE AND DESTRUCTION

         9.1 GENERAL. For the purposes of this Lease, the term "Casualty" shall
mean damage to or destruction of the Premises from any fire, earthquake, other
Act of God or any other cause.

         9.2 REBUILDING AND RESTORATION. In the event of a Casualty, Tenant
shall rebuild and restore the Premises substantially to the condition existing
immediately prior to the date of occurrence of the damage or destruction as
promptly as reasonably possible, provided that then-existing applicable law
shall allow Tenant to restore and rebuild the Premises to substantially the same
condition as existed immediately prior to the damage or destruction. Landlord
shall cooperate with Tenant in making available to Tenant insurance proceeds, if
any, for the purpose of enabling Tenant to rebuild and restore the Premises.

         9.3 TENANT'S ELECTION. Notwithstanding anything to the contrary
contained in this Article 9, Tenant shall have the right to terminate this Lease
in the event the Premises are damaged or destroyed by Casualty (a) at any time
within the last five (5) years of the Term and the cost to repair or restore the
Premises would exceed twenty-five percent (25%) of the replacement cost of the
Premises at such time, or (b) then-existing applicable law shall not allow
Tenant to restore and rebuild the Premises to substantially the same condition
as existed immediately prior to the damage or destruction. Tenant's election
shall be made by

written notice to Landlord given within thirty (30) days following Tenant's
receipt from Tenant's architect or construction consultant of the estimate of
the time required to complete the repair and restoration of the Premises. If
Tenant does not deliver such notice within such thirty-day period, Tenant may
not later terminate this Lease by reason of such Casualty. If Tenant delivers
such notice within such thirty-day period, then Tenant shall assign to Landlord
all of Tenant's rights to the insurance proceeds with respect to such Casualty,
and this Lease shall terminate effective as of the date of such Casualty.

         9.4 ABATEMENT OF RENTALS. In the event of damage to or destruction of
the Premises, the Base Rent and all other amounts payable by Tenant under this
Lease shall be proportionately reduced until the repair and restoration is
completed, based upon the extent to which the damage or destruction and/or the
making of repairs interferes with Tenant's use and enjoyment of the Premises.
All other obligations of Tenant under this Lease shall continue unaffected, all
subject to rental abatement insurance as provided in Section 11.2 below.

         9.5 LIABILITY FOR PERSONAL PROPERTY. In no event shall Landlord have
any liability for, nor shall Landlord be required to repair or restore, any
injury or damage to any of Tenant's trade fixtures, equipment, furniture or
personal property located on the Premises.

         9.6 WAIVER OF CERTAIN REMEDIES. Landlord and Tenant acknowledge that
the rights and obligations of the parties in the event of the damage or
destruction to the Premises are as set forth in this Article 9. Tenant hereby
expressly waives any rights to terminate this Lease upon damage or destruction
to the Premises, except as specifically provided by this Lease, including,
without limitation, any rights pursuant to the provisions of Sections 1932(2)
and 1933(4) of the California Civil Code, as amended, or any other, similar
provisions of law.

Tenant harmless from and against any and all losses, costs, claims, liabilities,
damages, expenses, and causes of action, including, without limitation,
reasonable attorneys' fees and costs arising out of or in any way connected
with: (a) any default by Landlord in the observance or performance of any of the
terms, covenants and obligations contained in this Lease on Landlord's part to
be observed or performed; or (b) any willful act or omission, or the sole
negligence, of Landlord or of the contractors, agents or employees of Landlord.
The provisions of this Section shall not affect the provisions of Section 20.4

damage or injury) occurring prior to such expiration or earlier termination.

                                   INSURANCE

         11.1 LIABILITY INSURANCE. Tenant, at Tenant's sole cost and expense,
shall obtain and maintain in effect during the Term a policy of commercial
general liability insurance with a minimum combined single limit of coverage of
not less than Five Million Dollars ($5,000,000), insuring against any liability
arising out of or in connection with Tenant's use or occupancy of the Premises.
Such insurance shall name Landlord and Landlord's mortgagee, if any, as
additional insureds, and shall provide that it is primary insurance and not
"excess over" or contributory with any other insurance in force for or on behalf
of Landlord. Such insurance policy shall eliminate cross-liability and shall
contain a severability of interest clause. Landlord shall have the right,
periodically during the Term, but not more frequently than once each five (5)
years, to require that Tenant increase the minimum liability amount specified in
this Section to an amount equal to the then-prevailing minimum liability limit
required by prudent Landlords of comparable buildings in San Francisco,
California, as determined by Landlord's insurance advisor and reasonably
concurred in by Tenant's insurance advisor.

         11.2 PROPERTY INSURANCE. Tenant shall obtain and maintain in effect
during the Term a policy of "special form" property insurance (including
mechanical breakdown coverage) with respect to the Property in the name of
Landlord with loss payable to Landlord, Landlord's mortgagee, if any, and
Tenant, as their interests may appear. The amount of such property insurance
shall be equal to the full replacement cost of the Premises. Such policy shall
insure against all risks of direct physical loss or damage, shall not include
coverage for the perils of flood or earthquake and shall include coverage for
any additional costs resulting from debris removal and reasonable amounts of
coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any

undamaged sections of the Premises required to be demolished or removed by
reason of the enforcement of any building, zoning, safety or land use laws as
the result of a covered cause of loss. Such policy shall also contain an agreed
valuation provision in lieu of any coinsurance clause, waiver of subrogation and
inflation guard protection causing an increase in the annual property insurance
coverage amount by a factor of not less than the Index figure published most
recently prior to each anniversary of the Commencement Date. Tenant shall also
obtain and maintain in effect during the Term rental interruption insurance in
an amount equal to the Base Rent, Taxes and other amounts payable by Tenant
under this Lease for a period of one (1) year following the date of any damage
or destruction resulting from a Casualty, if available on commercially
reasonable terms. If Tenant shall be unable to obtain such insurance, Tenant
shall give to Landlord written notice thereof.

         11.3 PERSONAL PROPERTY INSURANCE. Tenant, at its sole cost and expense,
shall also obtain and maintain in effect during the Term a policy of "special
form" property insurance with respect to Tenant's furniture, fixtures,
equipment, trade fixtures and personal property located on the Premises, in an
amount equal to the full replacement cost thereof.

         11.4 WORKER'S COMPENSATION INSURANCE. Tenant, at its sole cost and
expense, shall obtain and maintain in effect during the Term worker's
compensation insurance policies in such forms and amounts as are required by
applicable law.

         11.5 AUTOMOBILE INSURANCE. Tenant, at its sole cost and expense, shall
obtain and maintain in effect during the Term insurance covering the automobile
operations at the Premises, including, without limitation, the Parking Areas,
with a combined single limit of coverage of at least Five Million Dollars
($5,000,000), unless such coverage is provided by the policy of liability
insurance described in Section 11.1 above.

         11.6 INSURANCE CRITERIA. All insurance required under this Article 11
shall be issued by good and responsible companies qualified to do business in
the State of California, and having a rating of at least A-VII or better as
rated in the most recent edition of "Best's Insurance Guide." Each policy shall
expressly provide that the policy will not be canceled or altered without thirty
(30) days' prior written notice to the insureds. All insurance under this
Article 11 shall be primary and non-contributing with any insurance which may be
carried by any other party. Tenant shall deliver to Landlord certificates of
insurance evidencing the insurance coverage that Tenant is obligated to maintain
in effect under this Article II.

         11.7 WAIVER OF SUBROGATION. Landlord and Tenant each hereby waives any
and all rights to recovery against the other or the officers, employees, agents
and representatives of such other party, for losses or damage to such waiving
party or its property or the property

of others under its control, arising from any cause insured against under the
property insurance policies required to be carried by such party under this
Lease, or otherwise actually carried by such party, to the full extent of such
insurance coverage. Such waiver shall be effective only so long as the same is
permitted by each party's insurance carrier. In the event that either party's
insurance carrier notifies such party that the waiver will not be permitted,
then such party shall so notify the other party not later than thirty (30) days
prior to the expiration of the policy containing the waiver (or upon receipt of
such notice if the notice is received within the 30-day period) and such party
shall use its reasonable efforts to obtain replacement insurance containing such
waiver, provided that such waiver is available at no or nominal additional
premium cost.

ordinances, rules, regulations and requirements of governmental authorities now
in effect or which may hereafter be enacted or promulgated which relate to or
affect the exercise of such party's rights, or the performance of such party's
obligations, under this Lease.

         12.2 ALLOCATION. Regardless of whether Landlord or Tenant shall be
obligated to comply with any statutes, ordinances, rules, regulations or
requirements of governmental authorities under this Article 12, the costs and
expenses of constructing or installing any alterations, additions, improvements,
replacements or repairs to the Premises required by any such compliance shall be
allocated between Landlord and Tenant to the extent required and in the manner
provided for in Section 6.3 above.

representatives, nor Tenant's successors-in-interest, by operation of law or
otherwise, shall assign this Lease or sublease the Premises or any part thereof
(except to the extent permitted under Section 13.2 below), or mortgage, pledge,
transfer or hypothecate its leasehold interest (collectively, an "Assignment")
without Landlord's prior written consent, which, based on the standards set
forth in Section 13.7 below, shall not be unreasonably withheld. Any such
Assignment without Landlord's prior written consent shall be void and shall
constitute an Event of Default under Article 15 of this Lease.

         13.2 PERMITTED TRANSACTIONS.

                  (a) Landlord's consent shall not be required for any
Assignment to a Permitted Affiliate, as defined below ("Permitted Assignment"),
provided that (i) at the time of the Permitted Assignment, no Event of Default
exists or would exist with notice or passage of time; (ii) Landlord is provided
with written notice of the proposed Permitted Assignment describing the
transaction in reasonable detail; (iii) the Permitted Affiliate agrees in
writing to be bound by the terms of this Lease; and (iv) Landlord is provided
with a copy of the Proposed Assignment. The Permitted Assignment shall not
constitute a release of Tenant from further performance by Tenant under this
Lease, and Tenant shall remain liable and responsible for Base Rent and all
other obligations of Tenant under this Lease.

                  (b) Landlord's consent shall not be required for Tenant's
subleasing of up to 100,000 square feet of rentable area of the Premises from
time to time throughout the Term, but Landlord's consent shall be required for
any subleases exceeding such limit.

         13.3 PERMITTED AFFILIATE. The term "Permitted Affiliate" means a person
or entity that controls, is controlled by or is under common control with
Tenant; a person or entity with which Tenant shall merge or consolidate; and/or
a person or entity who acquires all or substantially all of the assets of
Tenant. "Control" means the direct or indirect ownership of more than fifty
percent (50%) of the voting securities of an entity or the possession of the
right to vote more than fifty percent (50%) of the voting interest in the
ordinary direction of the entity's affairs.

         13.4 NOTICE TO LANDLORD. Tenant shall give Landlord written notice of
its desire to make any Assignment for which Landlord's consent is required under
this Article 13. At the time of giving such notice, Tenant shall provide
Landlord with a copy of the proposed Assignment (including the sublease
documents or the financing documents, as applicable), which shall include a
covenant by the proposed assignee or sublessee, as applicable, in favor of
Landlord to abide by the terms of this Lease (applicable to the subleased
premises, in the case of a sublease), and such information as Landlord may
reasonably request concerning the proposed assignee, sublessee or lender, to
assist Landlord in making an informed judgment regarding the financial
condition, reputation, operation and general desirability of the proposed
assignee, sublessee, or lender, as applicable. Landlord shall then have a period
of ten (10) business days following receipt of such notice within which to
notify Tenant in writing of Landlord's decision.

         13.5 APPROVED ASSIGNMENTS. In the event of any approved Assignment or
any Permitted Assignment, the rights of the assignee or sublessee thereunder
shall be subject to

all of the terms, conditions and provisions of this Lease, including, without
limitation, restrictions on use and the covenant to pay Base Rent. If the
Landlord consents to any Assignment for which Landlord's consent is required
under this Article 13, Tenant shall have the right thereafter to enter into such
Assignment with the proposed assignee or sublessee upon the terms and conditions
set forth in the notice provided to Landlord. If Tenant shall default in the
payment of Base Rent to Landlord, then Landlord shall be authorized to collect
any rent due under any subleases directly from the sublessees, and payment of
rent by such sublessees shall satisfy their obligation to pay rent to Tenant
under their respective sublease.

         13.6 NO WAIVER. Consent by Landlord to a particular Assignment shall
not be deemed to be a consent to any other or subsequent transaction. Whether or
not Landlord consents to any such Assignment, Tenant shall pay Landlord an
administrative fee and any reasonable attorneys' fees or accountants' fees and
costs actually incurred by Landlord in connection with such proposed
transaction, in an aggregate amount not to exceed two thousand dollars ($2,000).
Such $2,000 limitation shall be adjusted every five (5) years throughout the
Term in the manner provided for adjustment of Base Rent in Section 4.4 above.

         13.7 STANDARD FOR CONSENT. Subject to the foregoing provisions, any
consents required by Landlord under this Article 13 shall not be unreasonably
withheld or delayed. In considering a proposed Assignment, it shall not be
unreasonable for Landlord to consider (a) the financial condition of the
proposed assignee, sublessee or lender, as applicable; (b) the character and
reputation of the assignee, sublessee or lender, as applicable; (c) the proposed
use of the Premises by the proposed assignee or sublessee, as applicable, (d)
whether an Event of Default shall have occurred and be continuing as of the date
on which Tenant shall request Landlord's consent to such Assignment; and (e) any
other reasonable economic and non-economic factors, in considering whether to
give its consent.

         13.8 EXCESS SUBLEASE RENTAL. If at any time Tenant shall enter into a
sublease or subleases which, in the aggregate, cover in excess of fifty percent
(50%) of the Rentable Area of the Premises (such portion of the Premises in
excess of fifty percent (50%) of the rentable area of the Premises being
referred to herein as the "Excess Area"), then Tenant shall pay to Landlord, as
and when received from the subtenant or subtenants under such subleases, fifty
percent (50%) of the Excess Sublease Rental (as defined below) attributable to
the Excess Area. For the purposes of this Lease, "Excess Sublease Rental" shall
mean the rentals and other economic consideration received by Tenant as a result
of such sublease or subleases and with respect to the Excess Area (less
reasonable, bona fide finders' fees or leasing commissions payable to a third
party in connection with such sublease or subleases, less reasonable attorneys'
fees and costs paid in connection with such sublease or subleases

subleases), and less tenant improvement costs paid by Tenant in connection with
such subleases, all as allocable to Excess Area), whether denominated as rent or
otherwise, which exceed, in the aggregate, the Base Rent, Taxes and any other
amounts which Tenant is obligated to pay to Landlord under this Lease (prorated
to reflect obligations allocable to the Excess Area). Tenant's payment of such
portion of the Excess Sublease Rental to Landlord shall not affect or reduce any
other obligation of Tenant under this Lease. At Landlord's request, Tenant shall
deliver to Landlord such evidence of the rentals and other economic
consideration received by Tenant as a result of any such sublease, and the
amounts deducted therefrom for purposes of calculating Landlord' share of such
rentals and other economic consideration, as Landlord shall reasonably require
from time to time.

                                ENTRY BY LANDLORD

         14.1 ENTRY. Landlord shall have the right to enter the Premises at any
reasonable time after giving Tenant not less than twenty-four (24) hours prior
written notice (except in the event of emergency, in which case such notice as
shall be reasonable under the circumstances shall be given) to: (a) inspect the
Premises; (b) exhibit the Premises to prospective purchasers, lenders or, during
the last six (6) months prior to the Expiration Date, tenants; (c) determine
whether Tenant is performing all of its obligations hereunder; (d) post notices
of non-responsibility; and (e) make repairs, alterations or improvements
required of Landlord hereunder to any portion of the Building, provided all such
work will be done as promptly as reasonably practicable and so as to cause as
little interference to Tenant as reasonably practicable. Subject to the
foregoing and Landlord's indemnification obligations under Section 10.2 of this
Lease, Tenant hereby waives any claim for damages for any injury to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises or any other loss occasioned by such entry.

         14.2 ACCESS. At all times, Landlord shall have and retain a key with
which to unlock all of the doors of the Premises (excluding Tenant's vaults,
safes and secure or proprietary areas designated in writing by Tenant). Landlord
shall have the right to use any and all means which Landlord may deem reasonable
under the circumstances to open such doors in an emergency in order to obtain
entry into the Premises, and any entry to the Premises obtained by Landlord by
any such means shall not be construed or deemed to be a forcible or unlawful
entry into or a detainer of the Premises or an eviction, actual or constructive,
of Tenant from the Premises or any portion thereof.

         15.1 EVENTS OF DEFAULT. The occurrence of any one or more of the
following events (each, an "Event of Default") shall constitute a default under
this Lease by Tenant:

                  (a) Tenant fails to pay any Base Rent, Taxes or any other
amount payable by Tenant under this Lease as and when the same becomes due and
payable, and such failure continues for more than five (5) days after Landlord
gives written notice thereof to Tenant; or

                  (b) Tenant fails to perform or observe any other agreement,
covenant or obligation contained in this Lease to be performed by Tenant as and
when performance is due, and such failure continues for more than thirty (30)
days after Landlord gives written notice thereof to Tenant; provided, however,
that if any such failure to perform by Tenant is not reasonably susceptible of
cure within such thirty-day period, then such failure to perform shall not
constitute an Event of Default provided that Tenant shall commence to cure such
failure to perform within such thirty-day period and shall thereafter prosecute
such cure diligently to completion; or

                  (c) Tenant (i) files, or consents by answer or otherwise to
the filing against Tenant of, a petition for relief, reorganization or
arrangement or any other petition in bankruptcy or to take advantage of any
bankruptcy or insolvency law of any jurisdiction; (ii) makes a general
assignment for the benefit of its creditors; (iii) consents to the appointment
of a custodian, receiver, trustee or other officer with similar powers for
Tenant or any substantial part of its property; or (iv) takes action for the
purpose of any of the foregoing; or

jurisdiction, without consent by Tenant, enters an order appointing a custodian,
receiver, trustee or other officer with similar powers with respect to Tenant or
with respect to any substantial part of its property, or constituting an order
for relief or approving a petition for relief, reorganization management or any
other petition in bankruptcy or to take advantage of any bankruptcy or
insolvency law of any jurisdiction, or ordering the dissolution, winding up or
liquidation of Tenant, or if any such petition is filed against Tenant and such
petition is not be dismissed within ninety (90) days; or

                  (e) This Lease or any estate of Tenant hereunder is levied
upon under any attachment or execution and such attachment or execution is not
vacated within ninety (90) days.

         15.2 RIGHT TO TERMINATE. If an Event of Default shall occur, Landlord
at any time thereafter shall have the right to terminate this Lease by written
notice given to Tenant. Upon such termination, Landlord shall have the right to
recover from Tenant:

                  (a) The worth at the time of award of all unpaid Rent which
had been earned at the time of termination;

                  (b) The worth at the time of award of the amount by which all
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided;

                  (c) The worth at the time of award of the amount by which all
unpaid rent 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; and

                  (d) All other amounts 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 of things would be likely to
result therefrom, including, without limitation, any penalties or fees incurred
by Landlord and charged by the applicable lender with respect to the
Construction Loan and/or the Landlord Financing in any way resulting from
Tenant's failure to pay Base Rent. The "worth at the time of award" of the
amounts referred to in subparagraphs (a) and (b) above shall be computed by
allowing interest at the maximum annual interest rate allowed by law. The "worth
at the time of award" of the amount referred to in subparagraph (c) above shall
be computed by discounting such amount at the discount rate of the Federal
Reserve Bank of San Francisco at the time of award plus 1%.

         15.3 RIGHT OF ENTRY. In the event of any termination of this Lease by
reason of an Event of Default, Landlord shall have the immediate right to enter
upon and repossess the entire Premises (without regard to whether Tenant holds
title to any interest therein), and any personal property of Tenant may be
removed from the Premises and stored in any public warehouse at the risk and
expense of Tenant.

         15.4 CONTINUATION AFTER DEFAULT. If an Event of Default shall occur,
this Lease shall continue in effect for so long as Landlord does not terminate
Tenant's right to possession, and Landlord shall have the right to enforce all
of its rights and remedies under this Lease, including the right to recover all
rent as it becomes due under this Lease. It is the intention of the parties that
Landlord shall have the remedy described in California Civil Code Section
1951.4, which provides that a lessor may continue the lease in effect after the
lessee's breach and abandonment and recover rent as it becomes due, if the
lessee has the right to

sublease or assign, subject only to reasonable limitations. Acts of maintenance
or preservation or efforts to relet the Premises, the appointment of a receiver
upon initiative of Landlord to protect Landlord's interest under this Lease or
any other acts of Landlord, shall not constitute a termination of Tenant's right
to possession unless written notice of termination is given by Landlord to
Tenant.

         15.5 LANDLORD'S RIGHT TO CURE DEFAULTS. All agreements, covenants and
provisions to be performed or observed by either party under this Lease (unless
otherwise specified herein) shall be at such party's sole cost and expense. If
Tenant fails to pay any amount, other than rent, required to be paid by Tenant
hereunder or fails to perform any other act on Tenant's part to be performed
hereunder, Landlord has the right, but shall not be obligated, and without
waiving or releasing Tenant from any obligations of Tenant, to make any such
payment or to perform any such other act on Tenant's part to be made or
performed as provided in this Lease. All sums so paid by Landlord and all
necessary incidental costs are deemed additional rent hereunder and shall be
payable by Tenant to Landlord on demand, together with interest on all such sums
from the date of expenditure by Landlord to the date of repayment by Tenant at
the Interest Rate (as defined below). In addition to all other rights and
remedies of Landlord, Landlord shall have the same rights and remedies in the
event of the nonpayment of such amounts by Tenant as in the case of a default in
the payment of Base Rent. Any amount owing from Landlord to Tenant under this
Lease shall accrue interest from the date of expenditure by Tenant or the date
owing by Landlord, as applicable, to the date of repayment by Landlord at the
Interest Rate.

         15.6 TENANT'S RIGHT TO CURE DEFAULTS. In the event that Landlord shall
fail to perform any covenant, agreement or obligation to be performed by
Landlord under this Lease, within a reasonable period of time following notice
of such failure by Tenant to Landlord (which reasonable period of time shall be
thirty (30) days, unless such failure to perform is not reasonably susceptible
of cure within thirty (30) days, in which case Landlord shall have such
additional period of time to cure such failure to perform as may be necessary,
provided that Landlord is proceeding diligently), then Tenant shall have the
right to take whatever action is necessary in order to remedy Landlord's failure
to perform, at Landlord's sole cost and expense, provided that Tenant shall give
Landlord, and to any mortgagee of the Premises whose address has been provided
to Tenant in writing, written notice of Tenant's intent to take such action at
least five (5) days prior to taking any such action (in addition to the minimum
thirty (30) day notice period described above), and provided that Landlord
itself shall not have taken appropriate action within such 5-day period. If
within ten (10) days following Tenant's written demand for payment of Tenant's
costs incurred in taking any such action on Landlord's behalf (including a
reasonably detailed statement), Landlord shall not have paid such amount, then
such amount shall thereafter accrue interest at the Interest Rate, and Tenant
shall have the right to recover such

amount from Landlord. Tenant shall not have the right to deduct any disputed
amounts from Rent or to terminate this Lease for Landlord's failure to act as
required by this Section.

         15.7 CUMULATIVE REMEDIES. The remedies provided for in this Lease are
cumulative and are in addition to all other remedies available to Landlord and
Tenant at law or in equity by statute or otherwise.

         15.8 LATE CHARGES; INTEREST. Tenant acknowledges that late payment by
Tenant to Landlord of Base Rent will cause Landlord to incur costs not
contemplated by this Lease, the exact amount of such costs being extremely
difficult and impracticable to ascertain. Such costs include, without
limitation, processing and accounting charges, and late charges that may be
imposed on Landlord by the terms of any indebtedness secured by an encumbrance
covering the Premises. Therefore if Tenant shall fail to pay any installment of
Base Rent when due, and such failure shall continue for ten (10) days
thereafter, Tenant shall pay to Landlord on demand an additional sum equal to
five percent (5%) of the overdue amount as a late charge. The parties agree that
this late charge represents a fair and reasonable estimate of the costs that
Landlord will incur by reason of such late payment by Tenant. Acceptance of any
late charge shall not constitute a waiver of Tenant's default with respect to
the overdue amount, or prevent Landlord from exercising any of the other rights
and remedies available to Landlord. In addition, each installment of Base Rent
and any other amount payable by Tenant to Landlord under this Lease which shall
not have been paid within thirty (30) days after the same shall have become due
and payable shall bear interest at the Interest Rate from the date that the same
became due and payable until paid, whether or not any demand shall be made
therefor.

         15.9 SECURITY DEPOSIT.

                  (a) Concurrently with the execution of this Lease by the
parties, Tenant shall deliver to Landlord a portion of the Security Deposit
provided for in the Basic Lease Provisions in an amount equal to fifty percent
(50%) thereof, and within ten (10) days following the date on which Landlord
shall give to Tenant written notice that Landlord has obtained the site permit
entitling Landlord to commence construction of the Project, Tenant shall deliver
to Landlord the remaining fifty percent (50%) of the Security Deposit. Tenant
shall have the right, at any time and from time to time, to make the Security
Deposit in cash, by letter of credit ("Letter of Credit') or through pledge in
favor of Landlord of short-term investments such as deposit or money market
amounts and commercial paper maintained by Tenant in accordance with its
investment policy ("Pledged Investments"). The agreement creating the pledge of
the Pledged Investments shall be reasonably acceptable to Landlord and the
mortgagee of the Premises, if any. If at any time after the

making of the Security Deposit, Tenant shall desire to substitute cash, a Letter
of Credit and/or Pledged Investments for the Security Deposit then held by
Landlord, upon Tenant's delivery thereof to Landlord, Landlord shall release and
return to Tenant the cash, Letter of Credit and/or Pledged Investments then held
by Landlord as the Security Deposit. The Letter of Credit shall be issued for an
initial term of one year, and Tenant shall cause the Letter of Credit to be
renewed for successive twelve-month periods throughout the Term not less than
thirty (30) days prior to each expiration date of the Letter of Credit. Any
Letter of Credit shall entitle Landlord to make a draw thereunder upon
presentation of a sight draft in the amount of the draw, together with a signed
certification from Landlord under penalty of perjury stating that an Event of
Default under this Lease has occurred and is continuing, and that by reason
thereof, Landlord is entitled to make the requested draw under the Letter of
Credit.

                  (b) The Security Deposit shall be held by Landlord as security
for the faithful performance by Tenant of all of the covenants, agreements and
obligations under this Lease to be performed by Tenant during the Term. If
Tenant shall fail to pay Base Rent or other amounts payable by Tenant to
Landlord under this Lease, or if Tenant shall otherwise default with respect to
any provision of this Lease, Landlord shall have the right, but shall not be
obligated, to use, apply or retain all or any portion of the Security Deposit
for the payment of rental or any other amount which Landlord may expend or
become obligated to expend by reason of Tenant's default, to repair damages to
the Premises caused by Tenant or to compensate Landlord for any other loss or
damage which Landlord may suffer by reason of Tenant's default. If the Security
Deposit shall have been made by Letter of Credit or with Pledged Investments,
Landlord shall be entitled to make a draw under the Letter of Credit, or to
realize from the Pledged Investments, the amount described in the preceding
sentence, and to use, apply or retain such amount as provided therein. If
Landlord shall so use or apply any portion of the Security Deposit, Tenant
shall, within ten (10) days after Landlord's written demand therefor, deposit
with Landlord cash, a Letter of Credit or Pledged Investments in the amount so
used or applied by Landlord. Landlord shall not be required to keep the Security
Deposit separate from Landlord's other funds, and Tenant shall not be entitled
to any interest on the Security Deposit. Except as otherwise required by
subparagraph (c) below, Landlord shall return any cash, Pledged Investments
and/or Letter of Credit then held by Landlord on account of the Security Deposit
to Tenant within thirty (30) days following the expiration of this Lease, less
any amounts applied by Landlord in accordance with its rights under this Lease
or applicable law. In the event that Landlord shall transfer its interest in the
Premises, Landlord shall transfer any cash, Pledged Investments and/or Letter of
Credit then held by Landlord on account of the Security Deposit to Landlord's
transferee, and Landlord shall thereupon be released from all liability to
Tenant for return of the Security Deposit.

                  (c) Provided that no Event of Default shall have occurred and
be continuing at such time, effective as of (i) the date which is ninety (90)
days following the date on which Tenant shall have accepted possession of the
Premises and commenced the payment of Base Rent under this Lease, and provided
that Tenant's consolidated net worth as determined in accordance with generally
accepted accounting principals consistently applied for the six (6) months
preceding such 90-day period shall be equal to or greater than Tenant's
consolidated net worth as of the Effective Date, the Security Deposit shall be
reduced to an amount equal to two (2) months' Base Rent (provided that the
Security Deposit shall also be reduced to two (2) months' Base Rent as of any
later date on which the foregoing Tenant net worth test shall be satisfied for a
period of six (6) months), (ii) the date which is five (5) years following the
date on which Tenant shall have accepted possession of the Premises and
commenced the payment of Base Rent under this Lease, and provided that Tenant's
consolidated net worth as determined in accordance with generally accepted
accounting principals consistently applied for the six (6) months preceding such
date shall be equal to or greater than Tenant's consolidated net worth as of the
Effective Date, the Security Deposit shall be reduced to zero (provided that the
Security Deposit shall also be reduced to zero as of any later date on which the
foregoing Tenant net worth test shall be satisfied for a period of six (6)
months), and (iii) the date on which Tenant shall exercise Tenant's option to
acquire an undivided one-half interest in the Premises from Landlord pursuant to
the Option Agreement and shall provide Landlord with the Option Security (as
defined in the Option Agreement), if prior to the date specified in the
foregoing clause (i), the Security Deposit shall also be reduced to zero. On
each such date, or as soon thereafter as may be practicable, Landlord shall
cause to be returned to Tenant any cash, Letter of Credit and/or Pledged
Investments then held by Landlord on account of the Security Deposit which are
in excess of the reduced amount of the Security Deposit as of such date.
Landlord's obligation so to return to Tenant any Letter of Credit or Pledged
Investments then held by Landlord shall be conditioned upon Landlord's receipt
of cash, a Letter of Credit, an amended Letter of Credit and/or Pledged
Investments in any such reduced amount of the Security Deposit which is in
excess of zero.

Section 16.1, from and after the date of this Lease, Landlord shall not
mortgage, pledge, hypothecate, encumber or lease the Property without Tenant's
prior written consent, which consent shall not be unreasonably withheld or
conditioned upon the payment of fees or the satisfaction of any unreasonable
conditions; provided, however, that prior to the Commencement Date, Tenant shall

have the right to sell or convey the Property prior to the Commencement Date
without Tenant's prior written consent, which consent may be withheld in
Tenant's sole discretion, except that Tenant's consent shall not be required for
any sale, conveyance or transfer of all or any part of Landlord's interest in
the Premises for estate planning purposes to (a) an entity or entities
controlled by or under common control with Landlord (or either of Kaufman
Partnership or Kaufman Trust) or RK or (b) to RK's family members; provided,
however, that in the case of any such sale, conveyance or transfer, RK shall
directly manage and control the transferee. Tenant's consent shall not be
required for (i) the existing deeds of trust encumbering the Property ("Existing
Deeds of Trust"); (ii) the Construction Loan (as defined in, and subject to the
provisions of, the Improvement Agreement) and any deed of trust securing the
Construction Loan; or (iii) the permanent financing, and any deed of trust
securing the permanent financing, obtained by Landlord in order to refinance the
Construction Loan and finance Landlord's cost of owning the Premises ("Landlord
Financing"); provided, however, that the Landlord Financing shall comply with,
and is subject to, the applicable provisions of the Option Agreement. In the
event that Tenant is entitled to and does exercise its cure rights provided for
in the Option Agreement with respect to the Landlord Financing, Tenant shall be
entitled to offset any such amounts expended by Tenant against the Base Rent.

         16.2 SUBORDINATION OF LEASE. This Lease shall be subject and
subordinate at all times to the lien of all mortgages and deeds of trust in any
amount or amounts whatsoever (including all advances thereunder, renewals,
replacement, modifications, supplements, and extensions thereof) now or
hereafter placed on or against the Premises, or on or against Landlord's
interest or estate therein, all without the necessity of having further
instruments executed on the part of Tenant to effectuate such subordination;
provided that each mortgagee or beneficiary under any such mortgage or deed of
trust, shall agree in writing not to terminate or disturb Tenant's possession of
the Premises under this Lease in the event of foreclosure of such mortgage or
deed of trust or deed in lieu thereof, as the case may be, so long as an Event
of Default with respect to Tenant shall not have occurred and be continuing at
such time. Within twenty (20) days following Landlord's written request
therefor, Tenant shall execute and deliver such further instruments evidencing
such subordination of this Lease to the lien of any such mortgages or deeds of
trust as may be required by Landlord, and evidencing Tenant's agreement to
attorn to any such mortgagee or beneficiary under any mortgage or deed of trust
in the event of foreclosure or a deed in lieu of foreclosure, or other purchaser
or grantee in respect thereof, provided that any such instruments contain
written non-disturbance agreements from such mortgagees or beneficiaries in the
form provided above.

         16.3 SUBORDINATION OF DEED OF TRUST. Notwithstanding anything to the
contrary set forth above, any mortgagee or beneficiary under any mortgage or
deed of trust may at any

part, without any need to obtain Tenant's consent, by execution of a written
document subordinating such mortgage or deed of trust to this Lease to the
extent set forth in such document, and thereupon the Lease shall be deemed prior
to such mortgage or deed of trust to the extent set forth in such document
without regard to their respective dates of execution, delivery and/or
recording. In that event, to the extent set forth in such document, such
mortgage or deed of trust shall have the same rights with respect to this Lease
as would have existed if this Lease had been executed, and a memorandum thereof
recorded, prior to the execution, delivery and recording of the mortgage or deed
of trust.

provisions of this Lease may be subject to the approval of the Construction
Lender (as defined in the Improvement Agreement) and/or any lender providing the
Landlord Financing; Tenant shall reasonably cooperate with Landlord in good
faith in Landlord's efforts to obtain the Construction Loan and Landlord
Financing on satisfactory terms and at a reasonably competitive rate. In
connection therewith, if the Construction Lender or the lender providing the
Landlord Financing shall require reasonable and necessary modifications to this
Lease as a condition to providing such financing on satisfactory terms and at a
reasonably competitive rate, upon Landlord's written request, Tenant shall not
unreasonably withhold its consent to such modifications; provided, however, that
no such modification shall change the size, location or dimension of the
Premises or increase the amount of the rent or other amounts payable by Tenant
under this Lease or materially affect Tenant's rights or increase Tenant's
obligations hereunder.

taken as a result of the exercise of the power of eminent domain or any
agreement in lieu thereof, this Lease shall terminate as to the part so taken as
of the date of taking and, in the case of a partial taking, Tenant shall have
the right to terminate this Lease as to the balance of the Premises by giving
written notice to Landlord within thirty (30) days after such date; provided,
however, that a condition to the exercise by Tenant of such right to terminate
is that not less than twenty-five percent (25%) of the Premises shall have been
taken and the portion of the Premises remaining is not reasonably suitable for
Tenant's continued occupancy for the uses permitted under this Lease, taking
into account the business operations conducted by Tenant on the Premises. If
Landlord and Tenant cannot agree on whether the portion of the Premises
remaining is not reasonably suitable for Tenant's continued occupancy, then
either party shall have the right to refer such matter to arbitration in
accordance with the provisions of Section 20.24 of this Lease. The proceeds of

condemnation award or any conveyance in lieu thereof shall belong to and be paid
to Landlord, except that Tenant shall be entitled to petition or apply for and
to receive from the condemning authority a separate award (provided that such
separate award does not reduce the amount of Landlord's award) including any or
all of the following:

                  (a) A sum attributable to the taking of the alterations,
additions or improvements made to the Premises by Tenant at its expense, and/or
the taking of any furniture, fixtures, equipment, trade fixtures or personal
property which Tenant has the right to remove from the Premises pursuant to the
provisions of this Lease;

                  (b) A sum equal to the present value of any excess of the
prevailing market rental value of the Premises for the remainder of the Term,
exclusive of the alterations, additions or improvements for which Tenant is
compensated under subparagraph (a) above, over the discounted sum of the Base
Rent and Taxes payable for the remainder of the Term; provided, however, that
Tenant's rights under this subparagraph (b) shall be subordinate to the rights
of the Construction Lender or the lender providing the Landlord Financing, and
the appropriation of such proceeds by any such lender shall not give Tenant any
recourse against Landlord by reason thereof;

                  (c) A sum attributable to that portion of the award
constituting severance damages for the restoration of the Premises, compensation
to Tenant for business interruption, relocation or moving expenses; and

                  (d) A sum to compensate Tenant for loss of goodwill.

         17.2 ABATEMENT OF RENT. If any portion of the Premises shall be taken
in eminent domain or by conveyance in lieu thereof, and this Lease shall not be
terminated as provided in this Article 17 by reason thereof, as of the date of
such taking, the Base Rent and other applicable amounts payable by Tenant under
this Lease shall be equitably reduced in proportion to such taking.

         17.3 ADDITIONAL PROVISIONS. Each party agrees to execute and deliver to
the other party all instructions and directions to the condemning authority that
may be required to effectuate the provisions of this Article 17. Each party
waives the provisions of California Code of Civil Procedure Section 1265.130,
and any successor statute, allowing either party to file a petition to terminate
this Lease for a partial taking.

         18.1 GENERAL. The waiver by Landlord or Tenant of any breach of any
agreement, covenant or provision in this Lease will not be deemed to be a waiver
of any subsequent breach of the same or any other agreement, covenant or
provision of this Lease, nor will any custom or practice which may grow up
between Landlord and Tenant in the administration of this Lease be construed to
waive or to lessen the right of Landlord or Tenant to insist upon the
performance by Landlord or Tenant in strict accordance with this Lease. The
subsequent acceptance of Rent hereunder by Landlord or the payment of Rent by
Tenant will not be deemed to be a waiver of any preceding breach by Landlord or
Tenant of any agreement, covenant or provision in this Lease, other than the
failure of Tenant to pay the particular Rent so accepted, regardless of
Landlord's or Tenant's knowledge of such preceding breach at the time of
acceptance or payment of such rent.

         18.2 PAYMENT UNDER PROTEST. If at any time a dispute arises regarding
any amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay is asserted
shall have the right to make payment "under protest", and any such payment will
not be regarded as a voluntary payment. In addition, the right on the part of
such party to institute suit for the recovery of such sum will survive. If it is
adjudged that there was no legal obligation on the part of such party to pay
such sum or any part thereof, such party will be entitled to recover such sum or
so much thereof as it was not legally required to pay under the provisions of
this Lease, with interest thereon at the Interest Rate.

         18.3 WORK UNDER PROTEST. If at any time a dispute arises between the
parties hereto regarding any work to be performed by either of them under the
provisions hereof, the party against whom the obligation to perform the work is
asserted may perform such work and pay the cost thereof "under protest". The
performance of such work in no event shall be regarded as a voluntary
performance, and the right on the part of such party to institute suit for the
recovery of the costs of such work will survive. If it is adjudged that there
was no legal obligation on the part of such party to perform the same or any
part thereof, such party will be entitled to recover the cost of such work or
the cost of so much thereof as such party was not legally required to perform
under the provisions of this Lease, with interest thereon at the Interest Rate.

         18.4 NOTIFICATION. Whenever a payment is made or work is done "under
protest", as provided in this Article 18, the party doing so, before making any
such payment or doing any such work, must notify the other party in writing that
it is doing so "under protest".

case such notice as shall be reasonable under the circumstances shall be given)
in order to enable Landlord to conduct any inspection, monitoring, remediation

with any Hazardous Materials in or removed from the Premises, including any
complaints, notices, warnings or asserted violations in connection therewith.
Each party also shall supply to the other as promptly as possible copies of all
claims, reports, complaints, notices, warnings or asserted violations relating
in any way to the Premises. Each party shall deliver promptly to the other
copies of hazardous waste manifests reflecting the legal and proper disposal of
Hazardous Materials removed from the Premises.

harmless from and against any and all claims, liabilities, losses, expenses,

arising from or caused in whole or in part, directly or indirectly, by (x) the
presence in, on, under or about the Premises, or discharge in or from the
Premises, of any Hazardous Materials not placed, in, on, under or about the
Premises by Tenant or otherwise the responsibility of Tenant under this Article
19, excluding, however: (i) any naturally-occurring asbestos that may be
contained in any serpentine rock located on the Premises or any other
naturally-occurring materials; or (ii) any condition disclosed in the
Environmental Documents; (y) Landlord's use, storage, transportation, disposal,
release, threatened release, discharge or generation of Hazardous Materials to,

described in the foregoing clause (i) or (ii) above. The obligations of each
party pursuant to this Section 19.3 includes, without limitation, and whether
foreseeable or unforeseeable, all costs of any required or necessary repair,
cleanup, detoxification or decontamination of the Premises, and the preparation
and implementation of any closure, remedial action or other required plans in
connection therewith, which obligations shall survive the expiration or earlier

Landlord's right to recover Base Rent in the foregoing amounts shall be without
prejudice to Landlord's other rights and remedies by reason of any such holding
over by Tenant.

         20.2 LANDLORD'S INTEREST. The term "Landlord" as used herein shall mean
only the owner or owners at the times in question of fee title to the Premises.
In the event of a sale, conveyance or assignment by Landlord of Landlord's
interest in the Premises, Landlord shall be relieved, from and after the date of
such sale, conveyance or assignment, of any liability thereafter accruing upon
any of the agreements, obligations or covenants of Landlord under the Lease,
provided that the successor-in-interest of Landlord shall agree in writing to
assume such agreements, obligations and covenants of Landlord. In such event
Tenant agrees to look solely to the successor-in-interest of Landlord in and to
this Lease, provided that any funds in the hands of Landlord, in which Tenant
has an interest, and provided that any Letter of Credit and Pledged Investments,
shall be delivered to such successor-in-interest. This Lease shall not be
affected by any such sale, conveyance, or assignment, however, and Tenant agrees
to attorn to the purchaser or assignee, such attornment to be effective and
self-operative without the execution of any further instruments on the part of
any of the parties to this Lease.

         20.3 QUIET ENJOYMENT. Landlord hereby covenants in favor of Tenant
that, provided that Tenant shall pay all rent and perform all other covenants,
agreements and obligations of Tenant under this Lease, Tenant shall have and
enjoy quiet possession of the Premises throughout the Term without any hindrance
or interruption by Landlord or any person claiming by, through or under
Landlord, subject to the terms and conditions of this Lease.

         20.4 LANDLORD'S LIABILITY. To the extent that Landlord shall have
liability under this Lease, the liability of Landlord under this Lease or
otherwise in connection with the Premises or the Building shall be limited to
Landlord's interest in the Building, and in no event shall any other assets of
Landlord or any assets of any constituent partner or member of Landlord be
subject to any liability arising out of or in connection with this Lease, or the
Building. Notwithstanding anything to the contrary contained in this Lease, in
no event shall Landlord be liable for any consequential damages, special damages
or lost profits sustained by Tenant.

         20.5 NO MERGER. The voluntary or other surrender of this Lease by
Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at
the option of Landlord, either terminate any or all existing subleases or
operate as an assignment to Landlord of any or all of such subleases.

         20.6 SURRENDER OF PREMISES. At the expiration of the Term or upon
earlier termination of this Lease, Tenant shall surrender to Landlord possession
of the Premises, in the same condition as received, reasonable wear and tear and
damage by casualty excepted. Any personal property of Tenant not removed from
the Premises shall be deemed to have been abandoned by Tenant and shall
thereupon become the property of Landlord.

         20.7 ESTOPPEL CERTIFICATE. At any time and from time to time, but in no
event later than twenty (20) days following a request therefor by the other
party, each party shall execute, acknowledge and deliver to the other party, a
certificate certifying: (a) the Commencement and Expiration Dates of this Lease;
(b) whether there are then existing any defaults by Tenant or Landlord in the
performance of its obligations under this Lease (and, if so, specifying the
same); (c) that this Lease is unmodified and in full force and effect (or, if
there have been modifications, that this Lease is in full force and effect, as
modified, and stating the date and nature of each modification); (d) the
capacity of the person executing such certificate, and that such person is duly
authorized to execute the same on behalf of such party; (e) the date, if any, to
which rent and other sums payable hereunder have been paid; (f) that no notice
has been received by such party of any default which has not been cured, except
as to defaults specified in the certificate; (g) the amount of any Security
Deposit and prepaid rent; and (h) such other matters as the other party may
request. Any such certificate may be relied upon by any prospective purchaser
of, or any existing or prospective mortgagee or beneficiary under any deed of
trust affecting, the Premises or any part thereof, and by any other party
specified by the requesting party.

         20.8 NOTICES. All notices and other communications which may or are
required or permitted to be given by either party to the other hereunder shall
be in writing and shall be deemed to have been given when personally delivered
or transmitted by private nationally recognized overnight courier service, or
forty-eight (48) hours after deposit in the United States mail, certified or
registered, with return receipt requested, postage prepaid, and addressed as
follows: prior to the date on which Tenant accepts possession of the Premises,
at Tenant's address prior to occupancy set out in the Basic Lease Provisions,
and thereafter to Tenant at the address for Tenant set out in the Basic Lease
Provisions, or to such other place as Tenant may from time to time designate in
a notice to Landlord; to Landlord at the address specified in the Basic Lease
Provisions, or to such other place as Landlord may from time to time designate
in a notice to Tenant.

         20.9 SUCCESSORS. Subject to the provisions of Article 13 of this Lease,
all of the terms, covenants and conditions contained in this Lease shall be
binding upon, and shall inure to the benefit of, the heirs, executors,
administrators, successors and assigns of the parties hereto.

         20.10 ATTORNEYS' FEES. In the event of any action or proceeding brought
by either party against the other under this Lease, the prevailing party shall
be entitled to recover court costs and the fees of its attorneys in such action
or proceeding (whether at the administrative, trial or appellate levels or by
arbitration) in such amount as the court or administrative body may award. The
"prevailing party" shall be the party which obtains substantially the result
sought, whether by settlement, judgment, dismissal or arbitration award.

         20.11 WAIVER. The failure of Landlord to exercise its rights in
connection with any breach by Tenant of any provision of this Lease shall not be
deemed to be a waiver of such provision or any subsequent breach or violation of
the same or any other provision of this Lease. The subsequent acceptance of rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
or violation by Tenant of any provision of this Lease other than the failure of
Tenant to pay the particular rent so accepted, regardless of Landlord's
knowledge of such preceding breach or violation at the time of acceptance of
such rent.

         20.12 CAPTIONS. The captions and headings of the Articles and Sections
in this Lease are for convenience only and shall not in any way limit or be
deemed to construe or interpret the terms and provisions of this Lease.

         20.13 TIME OF ESSENCE. Time is of the essence of this Lease and of all
provisions hereof, except as otherwise provided herein.

         20.14 INTEREST RATE. As used herein, the term "Interest Rate" shall
mean a per annum rate of interest equal to three percent (3%) plus the rate most
recently announced by Wells Fargo Bank, N.A. (or any successor thereof), at its
main office in San Francisco, California, as its "Prime Rate", serving as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, but in no event in excess of the maximum applicable
usury limitation.

         20.15 GOVERNING LAW. This Lease shall be governed by, and construed and
enforced in accordance with, the laws of the State of California. Landlord and
Tenant agree to submit to jurisdiction in the City and County of San Francisco
for any legal proceedings.

         20.16 ENTIRE AGREEMENT. The terms of this Lease are intended by the
parties as a final expression of their agreement with respect to such terms as
are included in this Lease

                                     xxxix
<PAGE>

and shall supersede any prior agreements, memoranda or other written
communications regarding this Lease. The parties further intend that this Lease
constitutes the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial proceedings, if
any, involving this Lease. Notwithstanding the foregoing, nothing contained
herein shall limit or affect in any manner the provisions of the Option
Agreement.

         20.17 INVALIDITY. If any provision of this Lease or the application
thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such provision
to persons or circumstances other than those as to which it is invalid or
unenforceable, shall not be affected thereby, and each provision of this Lease
shall be valid and be enforceable to the full extent permitted by law.

         20.18 AUTHORITY. If Tenant executes this Lease as a corporation, a
partnership or limited liability company, each of the persons executing this
Lease on behalf of Tenant does hereby covenant and warrant that Tenant is a duly
authorized and existing entity, that Tenant has full right and authority to
enter into this Lease, and that each and all of the persons on behalf of Tenant
are authorized to do so. Upon Landlord's request, Tenant shall provide Landlord
with evidence reasonably satisfactory to Landlord confirming the foregoing
covenants and warranties.

         20.19 NO OFFER. No contractual or other rights shall exist between
Landlord and Tenant with respect to the Premises until both have executed and
delivered this Lease, notwithstanding that Landlord has delivered to Tenant an
unexecuted copy of this Lease. The submission of this Lease to Tenant shall not
constitute the grant of an option for the Tenant to lease, or otherwise create
any interest by Tenant in, the Premises. The execution of this Lease by Tenant
and return to Landlord shall not be binding upon Landlord, notwithstanding any
time interval, until Landlord has in fact executed and delivered this Lease to
Tenant.

         20.20 BROKERS. Each party hereto represents and warrants that it has
dealt with no broker, finder or salesperson in connection with this Lease, and
each party hereto shall indemnify, defend and hold the other party harmless from
and against and all losses, costs, claims, damages, liabilities or causes of
action (including attorney's fees) arising out of or relating to any breach of
the foregoing representation and warranty or arising out of or relating to any
claim made by any broker, finder or salesperson claiming to have dealt with the
indemnifying party.

         20.21 AMENDMENTS. This Lease may not be modified or amended except by
an instrument executed by both parties hereto.

         20.22 MEMORANDUM OF LEASE. Concurrently with their execution of this
Lease, Landlord and Tenant shall execute, acknowledge and deliver a memorandum
of this Lease in the form of EXHIBIT C attached hereto, and shall cause such
memorandum to be recorded in the San Francisco County, California Official
Records at Landlord's expense.

         20.23 TITLE INSURANCE. If Tenant shall so require by written notice to
Landlord given within thirty (30) days following the date of this Lease, Tenant
shall have the right to obtain an owner's title insurance policy insuring Tenant
that Tenant holds a valid leasehold estate in the Property under this Lease,
subject only to such exceptions to title as Tenant shall approve. Such title
insurance policy shall be in such liability amount and shall be issued by such
title insurance company as Tenant shall require. Tenant shall pay the premium
and endorsement charges for such title insurance policy. Such title insurance
policy shall not be a condition to Tenant's obligations under this Lease.

         20.24 ARBITRATION. Whenever in this Lease it is provided that a matter
shall be decided by arbitration, or if the parties shall otherwise agree to
arbitration, the matter shall be decided by expedited arbitration before a
single arbitrator mutually decided upon by Landlord and Tenant within thirty
(30) days following the date of any party's demand for arbitration. The
arbitrator shall be an impartial individual who is acceptable to Landlord and
Tenant, who is experienced in real estate law and has offices located in the
Counties of San Francisco, Alameda, Marin, Contra Costa or San Mateo, and who
has not been previously employed by either Landlord or Tenant. If the parties
shall be unable to agree upon the arbitrator, the arbitrator shall be selected
in accordance with the applicable procedures of the Commercial Arbitration Rules
of the American Arbitration Association. The arbitration shall take place within
fifteen (15) days after the date of selection of the arbitrator. The arbitrator
shall be obligated to render his or her decision within five (5) business days
following the date on which the arbitration shall be concluded, or as soon
thereafter as such arbitrator can reasonably render such decision. Such
arbitration shall be held under the auspices of the San Francisco office of the
American Arbitration Association, unless the American Arbitration Association
refuses to administer the matter, in which case it shall be administered by the
arbitrator.

         20.25 CONSENTS, APPROVALS. If under this Lease, (a) a party shall have
the right to consent to or approve any matter, and (b) the time period within
which such party shall be obligated to grant or withhold its consent or approval
to such matter shall not be specified in this Lease, then unless such party
shall notify the other party that such party does not consent to or approve such
matter within five (5) days following its receipt of a written request for
consent or approval from the other party, such party shall be deemed to have
consented to or approved such matter for which consent or approval shall have
been requested.
