                          IRONSIDE TECHNOLOGIES INC.

                           2000 STOCK INCENTIVE PLAN

     1.   Purpose. The purpose of this 2000 Stock Incentive Plan (the "Plan") is
to enable Ironside Technologies Inc. (the "Company") to attract and retain the
services of (i) selected employees, officers and directors of the Company or any
parent or subsidiary of the Company and (ii) selected nonemployee agents,
consultants, advisers and independent contractors of the Company or any parent
or subsidiary of the Company. For purposes of this Plan, a person is considered
to be employed by or in the service of the Company if the person is employed by
or in the service of the Company or any parent or subsidiary of the Company (an
"Employer").

     2.   Shares Subject to the Plan. Subject to adjustment as provided below
and in Section 9, the shares to be offered under the Plan shall consist of
Common Shares of the Company, and the total number of Common Shares that may be
issued under the Plan shall be 2,250,000 shares plus (a) the number of Common
Shares reserved under the Company's Second Amended and Restated Stock Option
Plan, dated June 30, 2000 (the "Option Plan"), that are unissued and not subject
to outstanding options as of the effective date of the Plan and (b) the number
of Common Shares returned to the Option Plan after the effective date of the
Plan as a result of termination of options issued under the Option Plan. A total
of 14,800,000 shares were originally reserved for issuance under the Option
Plan. If an option granted under the Plan expires, terminates or is cancelled,
the unissued shares subject to that option shall again be available under the
Plan. If shares sold or awarded as a bonus under the Plan are forfeited to or
repurchased by the Company, the number of shares forfeited or repurchased shall
again be available under the Plan.

     3.   Effective Date and Duration of Plan.

          (a)  Effective Date. The Plan shall become effective as of October 19,
2000. No option granted under the Plan shall become exercisable and no shares
may be awarded as a bonus or sold under the Plan, however, until the Plan is
approved by the affirmative vote of the holders of a majority of the Common
Shares represented at a shareholders meeting at which a quorum is present or by
means of unanimous consent resolutions, and the exercise of any options granted
under the Plan before approval shall be conditioned on and subject to that
approval. Subject to this limitation, options may be granted at any time after
the effective date and before termination of the Plan, and shares may be awarded
as bonuses or sold under the Plan at any time after shareholder approval and
before termination of the Plan.

          (b)  Duration. The Plan shall continue in effect until July 31, 2010
or until all shares available for issuance under the Plan have been issued and
all restrictions on the shares have lapsed. The Board of Directors may suspend
or terminate the Plan at any time except with respect to options and shares
subject to restrictions then outstanding under the Plan. Termination shall not
affect any outstanding options, any right of the Company to repurchase shares or
the forfeitability of shares issued under the Plan.

     4.   Administration.

          (a)  Board of Directors. The Plan shall be administered by the Board
of Directors of the Company, which shall determine and designate the individuals
to whom awards shall be made, the amount of the awards and the other terms and
conditions of the awards. Subject to the provisions of the Plan, the Board of
Directors may adopt and amend rules and regulations relating to administration
of the Plan, advance the lapse of any waiting period, accelerate any exercise
date, waive or modify any restriction applicable to shares (except those
restrictions imposed by law) and make all other determinations in the judgment
of the Board of Directors necessary or desirable for the administration of the
Plan. The interpretation and construction of the provisions of the Plan and
related agreements by the Board of Directors shall be final and conclusive. The
Board of Directors may correct any defect or supply any omission or reconcile
any inconsistency in the Plan or in any related agreement in the manner and to
the extent it deems expedient to carry the Plan into effect, and the Board of
Directors shall be the sole and final judge of such expediency.

          (b)  Committee. The Board of Directors may delegate to any committee
of the Board of Directors (the "Committee") any or all authority for
administration of the Plan. If authority is delegated to the Committee, all
references to the Board of Directors in the Plan shall mean and relate to the
Committee, except (i) as otherwise provided by the Board of Directors and (ii)
that only the Board of Directors may amend or terminate the Plan as provided in
Sections 3 and 10.

          (c)  Officers. The Board of Directors may delegate to any officer or
officers of the Company authority to grant awards under the Plan, subject to any
restrictions imposed by the Board of Directors.

     5.   Types of Awards, Eligibility, General Rules.

          (a)  Types of Awards. The Board of Directors may, from time to time,
take the following actions, separately or in combination, under the Plan: (i)
grant Incentive Stock Options, as defined in Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), as provided in Sections 6(a) and 6(b);
(ii) grant options other than Incentive Stock Options ("Non-Statutory Stock
Options") as provided in Sections 6(a) and 6(c); (iii) award stock bonuses as
provided in Section 7; and (iv) sell shares subject to restrictions as provided
in Section 8.

          (b)  Eligibility; Limitations. Awards may be made to employees,
including employees who are officers or directors, and to other individuals
described in Section 1 selected by the Board of Directors; provided, however,
that only employees of the Company or any parent or subsidiary of the Company
(as defined in subsections 424(e) and 424(f) of the Code) are eligible to
receive Incentive Stock Options under the Plan. The Board of Directors shall
select the individuals to whom awards shall be made and shall specify the action
taken with respect to

                                       2
<PAGE>

each individual to whom an award is made. At the discretion of the Board of
Directors, an individual may be given an election to surrender an award in
exchange for the grant of a new award. No employee may be granted options for
more than an aggregate of 5,000,000 Common Shares in the calendar year in which
the employee is hired or 1,000,000 Common Shares in any other calendar year.

          (c)  Repurchase Rights in the Event of Termination of Employment. If,
in connection with shares sold pursuant to the Plan (including shares sold upon
exercise of options granted pursuant to the Plan) to persons other than
officers, directors or consultants of the Company, the Board of Directors
establishes provisions giving the Company a right to repurchase such shares, the
repurchase rights shall be limited to (i) a right to repurchase the shares at a
price not less than the fair market value of the shares on the date of
termination of employment, which right shall terminate at such time as the
Common Stock becomes publicly traded, and (ii) a right to repurchase the shares
at the original purchase price, provided that such right lapses at the rate of
at least 20% of the shares per year over 5 years from the date the shares are
sold or the option is granted (without respect to the date the option was
exercised or became exercisable). Any such right to repurchase may only be
exercised for cash or cancellation of a promissory note given as payment for the
shares and only within 90 days of termination of the person's employment (or in
the case of shares issued upon exercise of options after the date of
termination, within 90 days after the date of the exercise).

          (d)  Information. Financial statements of the Company will be provided
annually to each optionee under the Plan and to each person who holds Common
Shares acquired pursuant to the Plan; provided, however, that this requirement
shall not apply to key employees whose duties in connection with the Company
assure them access to equivalent information.

     6.   Option Grants.

          (a)  General Rules Relating to Options.

               (i)  Terms of Grant. The Board of Directors may grant options
     under the Plan. With respect to each option grant, the Board of Directors
     shall determine the number of shares subject to the option, the exercise
     price, the period of the option, the time or times at which the option may
     be exercised and whether the option is an Incentive Stock Option or a Non-
     Statutory Stock Option. At the time of the grant of an option or at any
     time thereafter, the Board of Directors may provide that an optionee who
     exercised an option with Common Shares of the Company shall automatically
     receive a new option to purchase additional shares equal to the number of
     shares surrendered and may specify the terms and conditions of such new
     options.

               (ii)  Exercise of Options. Except as provided in Section 6(a)(iv)
     or as determined by the Board of Directors, no option granted under the
     Plan may be exercised unless at the time of exercise the optionee is
     employed by or in the service of the

                                       3
<PAGE>

     Company and shall have been so employed or provided such service
     continuously since the date the option was granted. Except as provided in
     Sections 6(a)(iv) and 9, options granted under the Plan may be exercised
     from time to time over the period stated in each option in amounts and at
     times prescribed by the Board of Directors, provided that options may not
     be exercised for fractional shares and further provided that each option
     granted to a person who is not an officer, director or consultant of the
     Company shall become exercisable at the rate of at least 20 percent of the
     shares covered by the option per year over the first five years after the
     date of the grant. Unless otherwise determined by the Board of Directors,
     if an optionee does not exercise an option in any one year for the full
     number of shares to which the optionee is entitled in that year, the
     optionee's rights shall be cumulative and the optionee may purchase those
     shares in any subsequent year during the term of the option.

               (iii)  Nontransferability. Each option granted under the Plan by
     its terms (i) shall be nonassignable and nontransferable by the optionee,
     either voluntarily or by operation of law, except by will or by the laws of
     descent and distribution of the state or country of the optionee's domicile
     at the time of death, and (ii) during the optionee's lifetime, shall be
     exercisable only by the optionee; provided, however, that the Board of
     Directors may permit a Non-Statutory Stock Option to be transferable (x) to
     a trust under which the option is to be passed to beneficiaries on the
     death of the optionee and (y) by gift to immediate family members of the
     optionee. For this purpose, the term "immediate family member" shall mean
     any child, stepchild, grandchild, parent, stepparent, grandparent, spouse,
     sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law,
     brother-in-law, or sister-in-law, and shall include adoptive relationships.

               (iv)   Termination of Employment or Service.

                      (A)  General Rule. Unless otherwise determined by the
          Board of Directors, if an optionee's employment or service with the
          Company terminates for any reason other than because of total
          disability or death as provided in Sections 6(a)(iv)(B) and (C), his
          or her option may be exercised at any time before the expiration date
          of the option or the expiration of 90 days after the date of
          termination, whichever is the shorter period, but only if and to the
          extent the optionee was entitled to exercise the option at the date of
          termination; provided, however, that the Board of Directors may not
          provide for a post-termination exercise period of less than 30 days.

                      (B)  Termination Because of Total Disability.  Unless
          otherwise determined by the Board of Directors, if an optionee's
          employment or service with the Company terminates because of total
          disability, his or her option may be exercised at any time before the
          expiration date of the option or before the date 12 months after the
          date of

                                       4
<PAGE>

          termination, whichever is the shorter period, but only if and to the
          extent the optionee was entitled to exercise the option at the date of
          termination; provided, however, that the Board of Directors may not
          provide for a post-termination exercise period of less than 6 months.
          The term "total disability" means a medically determinable mental or
          physical impairment that is expected to result in death or has lasted
          or is expected to last for a continuous period of 12 months or more
          and that, in the opinion of the Company and two independent
          physicians, causes the optionee to be unable to perform his or her
          duties as an employee, director, officer or consultant of the Employer
          and unable to be engaged in any substantial gainful activity. Total
          disability shall be deemed to have occurred on the first day after the
          two independent physicians have furnished their written opinion of
          total disability to the Company and the Company has reached an opinion
          of total disability.

                    (C)  Termination Because of Death. Unless otherwise
          determined by the Board of Directors, if an optionee dies while
          employed by or providing service to the Company, his or her option may
          be exercised at any time before the expiration date of the option or
          before the date 12 months after the date of death, whichever is the
          shorter period, but only if and to the extent the optionee was
          entitled to exercise the option at the date of death and only by the
          person or persons to whom the optionee's rights under the option shall
          pass by the optionee's will or by the laws of descent and distribution
          of the state or country of domicile at the time of death; provided,
          however, that the Board of Directors may not provide for a post-
          termination exercise period of less than 6 months.

                    (D)  Amendment of Exercise Period Applicable to Termination.
          The Board of Directors may at any time extend the 90-day and 12-month
          exercise periods any length of time not longer than the original
          expiration date of the option.  The Board of Directors may at any time
          increase the portion of an option that is exercisable, subject to
          terms and conditions determined by the Board of Directors.

                    (E)  Failure to Exercise Option.  To the extent that the
          option of any deceased optionee or any optionee whose employment or
          service terminates is not exercised within the applicable period, all
          further rights to purchase shares pursuant to the option shall cease
          and terminate.

                    (F)  Leave of Absence.  Absence on leave approved by the
          Employer or on account of illness or disability shall not be deemed a
          termination or interruption of employment or service.  Unless
          otherwise determined by the Board of Directors, vesting of options
          shall continue during a medical, family or military leave of absence,
          whether paid or unpaid, and vesting of options shall be suspended
          during any other unpaid leave of absence.

                                       5

               (v)  Purchase of Shares.  Unless the Board of Directors
     determines otherwise, shares may be acquired pursuant to an option granted
     under the Plan only upon the Company's receipt of written notice from the
     optionee of the optionee's binding commitment to purchase shares,
     specifying the number of shares the optionee desires to purchase under the
     option and the date on which the optionee agrees to complete the
     transaction, and, if required to comply with the Securities Act of 1933,
     containing a representation that it is the optionee's intention to acquire
     the shares for investment and not with a view to distribution.  Unless the
     Board of Directors determines otherwise, on or before the date specified
     for completion of the purchase of shares pursuant to an option exercise,
     the optionee must pay the Company the full purchase price of those shares
     in cash or by check or, with the consent of the Board of Directors, in
     whole or in part, in Common Shares of the Company valued at fair market
     value, restricted stock or other contingent awards denominated in either
     stock or cash and other legal forms of consideration.  Unless otherwise
     determined by the Board of Directors, any Common Shares provided in payment
     of the purchase price must have been previously acquired and held by the
     optionee for at least six months. The fair market value of Common Shares
     provided in payment of the purchase price shall be the closing price of the
     Common Shares last reported before the time payment in Common Shares is
     made or, if earlier, committed to be made, if the Common Shares is publicly
     traded, or another value of the Common Shares as specified by the Board of
     Directors.  No shares shall be issued until full payment for the shares has
     been made, including all amounts owed for tax withholding.  Each optionee
     who has exercised an option shall, immediately upon notification of the
     amount due, if any, pay to the Company in cash or by check amounts
     necessary to satisfy any applicable federal, state and local tax
     withholding requirements.  If additional withholding is or becomes required
     (as a result of exercise of an option or as a result of disposition of
     shares acquired pursuant to exercise of an option) beyond any amount
     deposited before delivery of the certificates, the optionee shall pay such
     amount, in cash or by check, to the Company on demand.  If the optionee
     fails to pay the amount demanded, the Company or the Employer may withhold
     that amount from other amounts payable to the optionee, including salary,
     subject to applicable law.  With the consent of the Board of Directors, an
     optionee may satisfy this obligation, in whole or in part, by instructing
     the Company to withhold from the shares to be issued upon exercise or by
     delivering to the Company other Common Shares; provided, however, that the
     number of shares so withheld or delivered shall not exceed the minimum
     amount necessary to satisfy the required withholding obligation.  Upon the
     exercise of an option, the number of shares reserved for issuance under the
     Plan shall be reduced by the number of shares issued upon exercise of the
     option (less the number of any shares surrendered in payment for the
     exercise price or withheld to satisfy withholding requirements).

               (vi) Limitations on Grants to Non-Exempt Employees.  Unless
     otherwise determined by the Board of Directors, if an employee of the
     Company or any parent or subsidiary of the Company is a non-exempt employee
     subject to the overtime compensation provisions of Section 7 of the Fair
     Labor Standards Act (the "FLSA"), any

                                       6
<PAGE>

     option granted to that employee shall be subject to the following
     restrictions: (i) the option price shall be at least 85 percent of the fair
     market value, as described in Section 6(b)(iv), of the Common Shares
     subject to the option on the date it is granted; and (ii) the option shall
     not be exercisable until at least 6 months after the date it is granted;
     provided, however, that this 6-month restriction on exercisability will
     cease to apply if the employee dies, becomes disabled or retires, there is
     a change in ownership of the Company, or in other circumstances permitted
     by regulation, all as prescribed in Section 7(e)(8)(B) of the FLSA.

          (b)  Incentive Stock Options.  Incentive Stock Options shall be
subject to the following additional terms and conditions:

               (i)  Limitation on Amount of Grants.  If the aggregate fair
     market value of stock (determined as of the date the option is granted) for
     which Incentive Stock Options granted under this Plan (and any other stock
     incentive plan of the Company or its parent or subsidiary corporations, as
     defined in subsections 424(e) and 424(f) of the Code) are exercisable for
     the first time by an employee during any calendar year exceeds $100,000,
     the portion of the option or options not exceeding $100,000, to the extent
     of whole shares, will be treated as an Incentive Stock Option and the
     remaining portion of the option or options will be treated as a Non-
     Statutory Stock Option.  The preceding sentence will be applied by taking
     options into account in the order in which they were granted.  If, under
     the $100,000 limitation, a portion of an option is treated as an Incentive
     Stock Option and the remaining portion of the option is treated as a Non-
     Statutory Stock Option, unless the optionee designates otherwise at the
     time of exercise, the optionee's exercise of all or a portion of the option
     will be treated as the exercise of the Incentive Stock Option portion of
     the option to the full extent permitted under the $100,000 limitation.  If
     an optionee exercises an option that is treated as in part an Incentive
     Stock Option and in part a Non-Statutory Stock Option, the Company will
     designate the portion of the stock acquired pursuant to the exercise of the
     Incentive Stock Option portion as Incentive Stock Option stock by issuing a
     separate certificate for that portion of the stock and identifying the
     certificate as Incentive Stock Option stock in its stock records.

               (ii) Limitations on Grants to 10 Percent Shareholders.  An
     Incentive Stock Option may be granted under the Plan to an individual (a
     "10 Percent Shareholder") possessing more than 10 percent of the total
     combined voting power of all classes of stock of the Company or any parent
     or subsidiary (as defined in subsections 424(e) and 424(f) of the Code)
     only if the option price is at least 110 percent of the fair market value,
     as described in Section 6(b)(iv), of the Common Shares subject to the
     option on the date it is granted and the option by its terms is not
     exercisable after the expiration of five years from the date it is granted.

                                       7
<PAGE>

               (iii)  Duration of Options.  Subject to Sections 6(a)(ii),
     6(a)(iv) and 6(b)(ii), Incentive Stock Options granted under the Plan shall
     continue in effect for the period fixed by the Board of Directors, except
     that by its terms no Incentive Stock Option shall be exercisable after the
     expiration of 10 years from the date it is granted.

               (iv)   Option Price.  The option price per share shall be
     determined by the Board of Directors at the time of grant.  Except as
     provided in Section 6(b)(ii), the option price shall not be less than 100
     percent of the fair market value of the Common Shares covered by the
     Incentive Stock Option at the date the option is granted.  The fair market
     value shall be the closing price of the Common Shares last reported before
     the time the option is granted, if the stock is publicly traded, or another
     value of the Common Shares as specified by the Board of Directors.

               (v)    Limitation on Time of Grant.  No Incentive Stock Option
     shall be granted on or after the tenth anniversary of the last action by
     the Board of Directors adopting the Plan or approving an increase in the
     number of shares available for issuance under the Plan, which action was
     subsequently approved within 12 months by the shareholders.

               (vi)   Early Dispositions. If within two years after an Incentive
     Stock Option is granted or within 12 months after an Incentive Stock Option
     is exercised, the optionee sells or otherwise disposes of Common Shares
     acquired on exercise of the Option, the optionee shall within 30 days of
     the sale or disposition notify the Company in writing of (i) the date of
     the sale or disposition, (ii) the amount realized on the sale or
     disposition and (iii) the nature of the disposition (e.g., sale, gift,
     etc.)

          (c)  Non-Statutory Stock Options.  Non-Statutory Stock Options shall
be subject to the following terms and conditions, in addition to those set forth
in Section 6(a) above:

               (i)    Option Price. The option price for Non-Statutory Stock
     Options shall be determined by the Board of Directors at the time of grant.
     The option price shall be not less than 85 percent of the fair market value
     of the Common Shares covered by the Non-Statutory Stock Option at the date
     the option is granted, except that the option price for a Non-Statutory
     Stock Option granted to a 10 Percent Stockholder shall be at least 110
     percent of the fair market value of the Common Shares covered by the option
     at the date the option is granted. The fair market value shall be
     determined in a manner consistent with that described in Section 6.2-4.

               (ii)   Duration of Options. Non-Statutory Stock Options granted
     under the Plan shall continue in effect for the period fixed by the Board
     of Directors; provided, however, that no Non-Statutory Stock Option shall
     be exercisable after the expiration of 10 years from the date it is
     granted.

                                       8

     7.   Stock Bonuses. The Board of Directors may award shares under the Plan
as stock bonuses in recognition of past services. Shares awarded as a bonus
shall be subject to the terms, conditions and restrictions determined by the
Board of Directors. The restrictions may include restrictions concerning
transferability and forfeiture of the shares awarded, together with any other
restrictions determined by the Board of Directors. The Board of Directors may
require the recipient to sign an agreement as a condition of the award, but may
not require the recipient to pay any monetary consideration other than amounts
necessary to satisfy tax withholding requirements. The agreement may contain any
terms, conditions, restrictions, representations and warranties required by the
Board of Directors. The certificates representing the shares awarded shall bear
any legends required by the Board of Directors. The Company may require any
recipient of a stock bonus to pay to the Company in cash or by check upon demand
amounts necessary to satisfy any applicable federal, state or local tax
withholding requirements. If the recipient fails to pay the amount demanded, the
Company or the Employer may withhold that amount from other amounts payable to
the recipient, including salary, subject to applicable law. With the consent of
the Board of Directors, a recipient may satisfy this obligation, in whole or in
part, by instructing the Company to withhold from any shares to be issued or by
delivering to the Company other Common Shares; provided, however, that the
number of shares so withheld or delivered shall not exceed the minimum amount
necessary to satisfy the required withholding obligation. Upon the issuance of a
stock bonus, the number of shares reserved for issuance under the Plan shall be
reduced by the number of shares issued, less the number of shares withheld or
delivered to satisfy withholding obligations.

     8.   Restricted Stock. The Board of Directors may issue shares under the
Plan for any legal consideration determined by the Board of Directors; provided,
however, that the purchase price for the shares shall be not less than 85
percent of the fair market value of the Common Shares on the date that the right
to purchase the shares is granted, except that the purchase price for shares
issued to a 10 Percent Shareholder shall be at least 100 percent of the fair
market value of the Common Shares on the date that the right to purchase the
shares is granted and provided further that such fair market value shall be
determined in a manner consistent with that described in Section 6(b)(iv).
Shares issued under the Plan shall be subject to the terms, conditions and
restrictions determined by the Board of Directors. Subject to Section 5(c), the
restrictions may include restrictions concerning transferability, repurchase by
the Company and forfeiture of the shares issued, together with any other
restrictions determined by the Board of Directors. All Common Shares issued
pursuant to this Section 8 shall be subject to a purchase agreement, which shall
be executed by the Company and the prospective purchaser of the shares before
the delivery of certificates representing the shares to the purchaser. Subject
to Section 5(c), the purchase agreement may contain any terms, conditions,
restrictions, representations and warranties required by the Board of Directors;
provided, however, that the right to purchase the shares shall be nonassignable
and nontransferable by the prospective recipient of the shares, either
voluntarily or by operation of law, except by will or by the laws of descent and
distribution of the state or country of such prospective recipient's domicile at
the time of death. The certificates representing the shares shall bear any
legends required by the Board of Directors. The Company may require any
purchaser of restricted stock to pay to the

                                       9
<PAGE>

Company in cash or by check upon demand amounts necessary to satisfy any
applicable federal, state or local tax withholding requirements. If the
purchaser fails to pay the amount demanded, the Company or the Employer may
withhold that amount from other amounts payable to the purchaser, including
salary, subject to applicable law. With the consent of the Board of Directors, a
purchaser may satisfy this obligation, in whole or in part, by instructing the
Company to withhold from any shares to be issued or by delivering to the Company
other Common Shares; provided, however, that the number of shares so withheld or
delivered shall not exceed the minimum amount necessary to satisfy the required
withholding obligation. Upon the issuance of restricted stock, the number of
shares reserved for issuance under the Plan shall be reduced by the number of
shares issued, less the number of shares withheld or delivered to satisfy
withholding obligations.

     9.   Changes in Capital Structure.

          (a)  Stock Splits, Stock Dividends. If the outstanding Common Shares
of the Company is hereafter increased or decreased or changed into or exchanged
for a different number or kind of shares or other securities of the Company by
reason of any stock split, combination of shares, dividend payable in shares,
recapitalization or reclassification, appropriate adjustment shall be made by
the Board of Directors in the number and kind of shares available for grants
under the Plan and in all other share amounts set forth in the Plan. In
addition, the Board of Directors shall make appropriate adjustment in the number
and kind of shares as to which outstanding options, or portions thereof then
unexercised, shall be exercisable, so that the optionee's proportionate interest
before and after the occurrence of the event is maintained. Notwithstanding the
foregoing, the Board of Directors shall have no obligation to effect any
adjustment that would or might result in the issuance of fractional shares, and
any fractional shares resulting from any adjustment may be disregarded or
provided for in any manner determined by the Board of Directors. Any such
adjustments made by the Board of Directors shall be conclusive.

          (b)  Mergers, Reorganizations, Etc. In the event of a merger,
amalgamation, consolidation, plan of exchange, acquisition of property or stock,
split-up, split-off, spin-off, reorganization or liquidation to which the
Company is a party or any sale, lease, exchange or other transfer (in one
transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company (each, a "Transaction"), the Board of Directors
shall, in its sole discretion and to the extent possible under the structure of
the Transaction, select one of the following alternatives for treating
outstanding options under the Plan:

               (i)  Outstanding options shall remain in effect in accordance
     with their terms.

               (ii) Outstanding options shall be converted into options to
     purchase stock in one or more of the corporations, including the Company,
     that are the surviving or acquiring corporations in the Transaction. The
     amount, type of securities subject thereto

                                       10
<PAGE>

     and exercise price of the converted options shall be determined by the
     Board of Directors of the Company, taking into account the relative values
     of the companies involved in the Transaction and the exchange rate, if any,
     used in determining shares of the surviving corporation(s) to be held by
     holders of shares of the Company following the Transaction. Unless
     otherwise determined by the Board of Directors, the converted options shall
     be vested only to the extent that the vesting requirements relating to
     options granted hereunder have been satisfied.

               (iii)  The Board of Directors shall provide a period of 30 days
     or less before the completion of the Transaction during which outstanding
     options may be exercised to the extent then exercisable, and upon the
     expiration of that period, all unexercised options shall immediately
     terminate. The Board of Directors may, in its sole discretion, accelerate
     the exercisability of options so that they are exercisable in full during
     that period.

          (c)  Dissolution of the Company. In the event of the dissolution of
the Company, options shall be treated in accordance with Section 9(b)(iii).

          (d)  Rights Issued by Another Corporation. The Board of Directors may
also grant options and stock bonuses and issue restricted stock under the Plan
with terms, conditions and provisions that vary from those specified in the
Plan, provided that any such awards are granted in substitution for, or in
connection with the assumption of, existing options, stock bonuses and
restricted stock granted, awarded or issued by another corporation and assumed
or otherwise agreed to be provided for by the Company pursuant to or by reason
of a Transaction.

     10.  Amendment of the Plan. The Board of Directors may at any time modify
or amend the Plan in any respect. Except as provided in Section 9, however, no
change in an award already granted shall be made without the written consent of
the holder of the award if the change would adversely affect the holder.

     11.  Approvals. The Company's obligations under the Plan are subject to the
approval of provincial, state and federal authorities or agencies with
jurisdiction in the matter. The Company will use its best efforts to take steps
required by provincial, state or federal law or applicable regulations,
including rules and regulations of the Securities and Exchange Commission and
any stock exchange on which the Company's shares may then be listed, in
connection with the grants under the Plan. The foregoing notwithstanding, the
Company shall not be obligated to issue or deliver Common Shares under the Plan
if such issuance or delivery would violate provincial, state or federal
securities laws.

     12.  Employment and Service Rights. Nothing in the Plan or any award
pursuant to the Plan shall (i) confer upon any employee any right to be
continued in the employment of an Employer or interfere in any way with the
Employer's right to terminate the employee's employment at will at any time, for
any reason, with or without cause, or to decrease the

                                       11
<PAGE>

employee's compensation or benefits, or (ii) confer upon any person engaged by
an Employer any right to be retained or employed by the Employer or to the
continuation, extension, renewal or modification of any compensation, contract
or arrangement with or by the Employer.

     13.  Rights as a Shareholder. The recipient of any award under the Plan
shall have no rights as a shareholder with respect to any Common Shares until
the date the recipient becomes the holder of record of those shares. Except as
otherwise expressly provided in the Plan, no adjustment shall be made for
dividends or other rights for which the record date occurs before the date the
recipient becomes the holder of record.

                                  POSSESSION
                                  ----------

          Tenant agrees that, if Landlord is unable to deliver possession of the
Premises to Tenant on or before the scheduled commencement of the term of this
Lease, this Lease shall not be void or voidable, nor shall Landlord be liable to
Tenant for any loss or damage resulting therefrom, but in such event the Term of
this Lease shall not commence until Landlord tenders possession of the Premises
to Tenant with the Tenant Improvements substantially completed. If Landlord
completes construction of the Tenant Improvements prior to the date scheduled,
Landlord shall deliver possession of the Premises to Tenant upon such completion
and the term of this Lease shall thereupon commence.

                                   ARTICLE 3

                                  BASIC RENT
                                  ----------

          (a)  Tenant agrees to pay Landlord Basic Rent for the Premises
(subject to adjustment as hereinafter provided) as follows:

          Months of Term                  Basic Rent/Per Month
          --------------                  --------------------

             01 - 60                           $38,092.60

The Basic Rent shall be paid monthly, in advance on the first (1st) day of each
calendar month during the term, commencing on the first (1st) month of the Lease
term and continuing on the first day of each month thereafter, except that the
first (1st) month's rent shall be paid on execution hereof.  If Tenant's
obligation to pay rent commences or ends on a day other than the first day of a
calendar month, then the rental for such period shall be prorated in the
proportion that the number of days this Lease is in effect during such period
bears to thirty.  In addition to the Basic Rent, Tenant agrees to pay as
additional rental the amount of rental adjustments and other charges required by
this Lease.  All rental shall be paid to Landlord, without prior demand and
without any deduction or offset, in lawful money of the United States of
America, at the address of Landlord designated on the signature page of this
Lease or to such other person or at such other place as Landlord may from time
to time designate in writing.

          (b)  Late Charges.   In the event Tenant fails to pay any installment
               ------------
of rent when due or in the event Tenant fails to make any other payment for
which Tenant is obligated under this Lease when due, then Tenant shall pay to
Landlord a late charge equal to 5% of the amount due to compensate Landlord for
the extra costs incurred as a result of such late payment.

          (a)  For the purpose of this Article  4, the following terms are
defined as follows:

               (i)   Tenant's Percentage.   That portion of the Project occupied

                     --------------------
Expenses which Landlord has included in Annual Basic Rent, which amount is
Tenant's Percentage of the actual Direct Expenses for 2000. If the Project is
less than ninety-five percent (95%) occupied during any calendar year of the
term, an adjustment shall be made in computing the Direct Expenses for such year
so that Direct Expenses shall be computed as though the Project were ninety-five
percent (95%) occupied.

               (iii) Direct Expenses.   The term "Direct Expenses" shall
                     ---------------

governmental authority or agency on the Project and the land on which the
Project is located (including a pro-rata portion of any taxes levied on any
common areas); any assessments levied in lieu of taxes; any non-progressive tax
on or measured by gross rentals received from the rental of space in the
Project; and any other costs levied or assessed by, or at the direction of, any
federal, state, or local government authority in connection with the use or
occupancy of the Premises or the parking facilities serving the Premises; any
tax on this transaction or any document to which Tenant is a party creating or
transferring an interest in the Premises, and any expenses, including cost of
attorneys or experts, reasonably incurred by Landlord in seeking reduction by
the taxing authority of the above-referenced taxes, less tax refunds obtained as
a result of an application for review thereof; but shall not include any net
income, franchise, capital stock, estate or inheritance taxes.

                     (B)   Operating costs consisting of costs incurred by
Landlord to the extent they relate to maintaining and operating the Project,

may have installed: (a) for the purpose of reducing operating costs, (b) to
comply with governmental

                                       3

rules and regulations promulgated after the date of substantial completion of
the Premises, and (d) any costs required by the CC&R's, as defined in Article 6,
affecting the Premises or by any corporation, committee or association formed in
connection therewith, provided that such cost together with interest at the
prime rate for money center banks plus 100 basis points as published from time
to time in the Wall Street Journal shall be amortized over such reasonable
period as Landlord shall determine in accordance with generally accepted
accounting principles, and only the monthly amortized cost shall be included in
Direct Expenses monthly.

                     (D) Tenant acknowledges that the Premises are subject to
assessments levied to secure bonds sold by the City of Pleasanton pursuant to
Consolidated Reassessment District 1993-1. Such Assessments shall be Landlord's
responsibility throughout the term of this Lease. Tenant hereby consents to the
formation of any other districts formed for maintenance, utilities, landscaping,
lighting, special service zones, fire district, water district, road extensions,
traffic mitigation, sports facilities or other improvements in the Project or
Bernal Corporate Park and to the re-financing of any assessment districts.
Tenant hereby waives any right of notice and protest in connection with the
formation and continued existence of the assessment districts so long as Tenant
is not required to pay any assessments for any assessment districts that are
specific to Bernal Corporate Park. Tenant shall execute all documents,
including, but not limited to, petitions and formal waivers of notice and
protest of formation, evidencing such consent and waiver upon request of
Landlord or the City of Pleasanton.

          (b)    Payment of Direct Expenses.
                 --------------------------

                 (i)   If Tenant's Percentage of the Direct Expenses paid or
incurred by Landlord for any calendar year exceeds the Direct Expenses Base
included in Tenant's rent, then Tenant shall pay such excess as additional rent.

                 (ii)  In addition, for each year after the first calendar year,
or portion thereof, Tenant shall pay Tenant's Percentage of Landlord's estimate
of the amount by which Direct Expenses for that year shall exceed the Direct
Expenses Base ("Landlord's Estimate"). This estimated amount shall be divided
into twelve equal monthly installments. Tenant shall pay to Landlord,
concurrently with the regular monthly rent payment next due following the
receipt of such statement, an amount equal to one monthly installment multiplied
by the number of months from January in the calendar year in which said
statement is submitted to the month of such payment, both months inclusive.
Subsequent installments shall be payable concurrently with the regular monthly
rent payments for the balance of that calendar year and shall continue until the
next calendar year's statement is rendered.

                 (iii) As soon as possible after the end of each calendar year,
Landlord shall provide Tenant with a reasonably detailed statement showing the
amount of Tenant's Percentage of Direct Expenses, the amount of Landlord's
Estimate actually paid by Tenant and the amount of the Direct Expenses Base.
Thereafter, Landlord shall reconcile the above amounts and shall either bill
Tenant for the balance due (payable on demand by Landlord) or credit any
overpayment by Tenant towards the next monthly installment of Landlord's
Estimate falling due, as the case may be.  For

                                       4
<PAGE>

purposes of making these calculations, in no event shall Tenant's Percentage of
the Direct Expenses be deemed to be less than the Direct Expenses Base.

          (c)  Even though the term has expired and Tenant has vacated the
Premises, when the final determination is made of Tenant's Percentage of Direct
Expenses for the year in which this Lease terminates, Tenant shall immediately
pay any increase due over the estimated expenses paid and, conversely, any
overpayment made in the event said expenses decrease shall be rebated by
Landlord to Tenant.

          (d)  Tenant shall have the right to inspect Landlord's books and
records for the Project for the prior calendar year at any time within twelve
(12) months after Tenant's receipt of Landlord's statement of the actual Direct
Expenses to verify the Direct Expenses for such calendar year.  Tenant shall
conduct such inspection during normal business hours at the office of Landlord's
property manager upon not less than two business days prior notice to Landlord.
If Tenant questions or disputes any Direct Expenses billed to Tenant, Tenant
shall notify Landlord in writing, and Landlord and Tenant shall attempt in good
faith to resolve any dispute regarding such expenses.  If Landlord and Tenant
fail to resolve such dispute within thirty days after Tenant has notified
Landlord of the expenses questioned, Tenant shall be permitted to conduct an
audit of Landlord's books and records of the Direct Expenses, using an
independent, licensed and reputable accounting firm, which audit shall be
completed no later than twelve (12) months from the date that Landlord's
statement of the actual Direct Expenses for the calendar year in question has
been delivered to Tenant.  If the audit discloses that the Direct Expenses
charged to Tenant for the period under review were overstated by five percent
(5%) or more, Landlord shall reimburse Tenant for the cost of the audit;
otherwise, the cost of the audit shall be paid by Tenant.  Landlord shall
promptly refund to Tenant the full amount of any overpayment made by Tenant.

                                ----------------

          Tenant, upon execution of this Lease, shall deposit with Landlord
the sum of One Hundred Fifty-Two Thousand Three Hundred Seventy Dollars and
40/100 ($152,370.40). Said sum shall be held by Landlord as security for the
faithful performance by Tenant of all of Tenant's obligations hereunder. If
Tenant defaults with respect to any provision of this Lease, including but not
limited to the provisions relating to the payment of rent, Landlord may (but
shall not be required to) use, apply or retain all or any part of this security
deposit for the payment of any rent or any other sum in default, or for the
payment of any other amount which Landlord may spend or become obligated to
spend by reason of Tenant's default or to compensate Landlord for any other loss
or damage which Landlord may suffer by reason of Tenant's default. If any
portion of the deposit is so used or applied, Tenant shall, upon demand, deposit
cash with Landlord in an amount sufficient to restore the security deposit to
its original amount. Tenant's failure to do so shall be a material breach of
this Lease. Landlord shall not be required to keep this security deposit
separate from its general funds, and Tenant shall not be entitled to interest on
such deposit. If Tenant shall fully and faithfully perform all of its
obligations under this Lease, the security deposit or any balance thereof shall
be returned to Tenant (or, at Landlord's option, to the last assignee of
Tenant's interests hereunder) at the expiration of the Lease

                                       5

term, provided that Landlord may retain the security deposit until such time as
any amount due from Tenant in accordance with Article 4 hereof has been
determined and paid in full. Provided that Tenant is not in default under this
Lease, the Security Deposit shall be reduced by applying amounts to Basic Rent
due for the 13th, 25th and 37th months of the Lease.

          Tenant shall use the Premises for general office use and shall not use
or permit the Premises to be used for any other purpose without the prior
written consent of Landlord.  Nothing contained herein shall be deemed to give
Tenant any exclusive right to such use in the Project.  Tenant shall not use or
occupy the Premises in violation of law or of the certificate of occupancy
issued for the Building or Project, and shall, upon written notice from
Landlord, discontinue any use of the Premises which is declared by any
governmental authority having jurisdiction to be a violation of law or of said
certificate of occupancy.  Tenant shall comply with any direction of any
governmental authority having   jurisdiction which shall, by reason of the
nature of Tenant's use or occupancy of the Premises, impose any duty upon Tenant
or Landlord with respect to the Premises or with respect to the use or
occupation thereof.  Tenant shall not do or permit to be done anything which
will invalidate or increase the cost of any fire, extended coverage or any other
insurance policy covering the Building and/or Project and/or property located
therein and shall comply with all rules, orders, regulations and requirements of
the Insurance Service Offices, formerly known as the Pacific Fire Rating Bureau
or any other organization performing a similar function.  Tenant shall promptly,
upon demand, reimburse Landlord for any additional premium charged for such
policy by reason of Tenant's failure to comply with the provisions of this
Article.  Tenant shall not do or permit anything to be done in or about the
Premises which will in any way obstruct or interfere with the rights of other
tenants or occupants of the Project, or injure them, or use or allow the
Premises to be used for any improper, immoral, unlawful or objectionable
purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about
the Premises. Tenant shall not commit or suffer to be committed any waste in or
upon the Premises. Tenant acknowledges that Landlord has recorded covenants,
conditions and restrictions against the Premises on February 18, 1987 as
Instrument Number 87/046032 in the Official Records of Alameda County (the
"CC&R's"). Tenant's use of the Premises shall be subject to and Tenant shall
comply with the CC&R's, as the same may be amended from time to time, provided
that any amendments do not materially diminish Tenant's rights under this Lease
or materially increase Tenant's obligations. Tenant acknowledges that there have
been and may be from time to time recorded easements and/or declarations
granting or declaring easements for parking, utilities, fire or emergency
access, and other matters. Tenant's use of the Premises shall be subject to and
Tenant shall comply with any and all such easements and declarations. Tenant's
use of the Premises shall be subject to such guidelines as may from time to time
be prepared by Landlord or the Bernal Corporate Park Owner's Association in
their sole discretion. Tenant acknowledges that governmental entities with
jurisdiction over the Premises may, from time to time promulgate laws, rules,
plans and regulations affecting the use of the Premises, including, but not
limited to, traffic management plans and energy conservation plans. Tenant's use
of the Premises shall be subject to and Tenant shall comply with any and all
such laws, rules, plans, and regulations. Tenant, at its sole cost, shall comply
with all laws relating to the storage, use and disposal of hazardous, toxic or
radioactive matter, to the extent brought into the Project by Tenant, its agents
or employees, including those materials identified in Sections 66680 through
66685 of Title 33 of the California Administrative Code, Division 4, Chapter 30

of any Toxic Materials, Tenant shall notify Landlord in writing at least ten
(10) days prior to their first appearance on the Premises.

          Any notice required or permitted to be given hereunder must be in
writing and may be given by personal delivery or by mail, or by nationally
recognized overnight delivery service, and if given by mail shall be deemed
sufficiently given if sent by registered or certified mail addressed to Tenant

Lease.  Either party may specify a different address for notice purposes by
written notice to the other except that the Landlord may in any event use the

          Landlord and Tenant warrants, each to the other, that it has had no
dealings with any real estate broker or agent in connection with the negotiation
of this Lease, except N/A, whose commission shall be payable by Landlord, and
that it knows of no other real estate broker or agent who is or might be
entitled to a commission in connection with the Lease. If either Landlord or
Tenant has dealt with any other person or real estate broker with respect to
leasing or renting space in the Project, such party shall be solely responsible
for the payment of any fee due said person or firm and shall hold the other
party free and harmless against any liability in respect thereto, including
attorneys' fees and costs.

          If Tenant holds over after the expiration or earlier termination of
the term hereof without the express written consent of Landlord, Tenant shall
become a Tenant at sufferance only, at a rental rate equal to one hundred fifty
percent (150%) of the rent in effect upon the date of such expiration (subject
to adjustment as provided in Paragraph 4 hereof and prorated on a daily basis),
and otherwise subject to the terms, covenants and conditions herein specified,
so far as applicable.  Acceptance by Landlord of rent after such expiration or
earlier termination shall not result in a renewal of this Lease.  The foregoing
provisions of this Article 9 are in addition to and do not affect Landlord's
right of re-entry or any rights of Landlord hereunder or as otherwise provided
by law.  If Tenant fails to surrender the Premises upon the expiration of this
Lease despite demand to do so by Landlord, Tenant shall indemnify and hold
Landlord harmless from all loss or liability, including without limitation, any
claim made by any succeeding tenant founded on or resulting from such failure to
surrender and any attorneys' fees and costs.

          (a) Tenant shall be liable for and shall pay, at least ten days before
delinquency, all taxes levied against any personal property or trade fixtures
placed by Tenant in or about the Premises.  If any such taxes on Tenant's
personal property or trade fixtures are levied against Landlord or Landlord's
property of if the assessed value of the Premises is increased by the inclusion
therein of a value placed upon such personal property or trade fixtures of
Tenant and if Landlord, after written notice to Tenant, pays the taxes based
upon such increased assessment, which Landlord shall have the right to do
regardless of the validity thereof, but only under proper protest if requested
by Tenant, Tenant shall, upon demand, repay to Landlord the taxes so levied
against Landlord, or the portion of such taxes resulting from such increase in
the assessment.

          (b) any improvements or alterations are made to Premises after the
commencement of the term, whether installed, and/or paid for by Landlord or
Tenant and whether or not affixed to the real property so as to become a part
thereof, are assessed for real property tax purposes at a valuation higher than
the valuation at which any improvements or alterations in other space in the
Project of tenants not separately charged are assessed, then the real property
taxes and assessment levied against the Project by reason of such excess
assessed valuation shall be deemed to be taxes levied against personal property
of Tenant and shall be governed by the provisions of Paragraph 10(a), above. If
the records of the County Assessor are available and sufficiently detailed to
serve as a basis for determining whether said improvements or alterations are
assessed at a higher valuation than improvements or alterations of tenants not
separately charged, such records shall be binding on both the Landlord and the
Tenant. If the records of the County Assessor are not available or sufficiently
detailed to serve as a basis for making said determination, the actual cost of
construction shall be used.

          Tenant acknowledges that, except as expressly stated herein, neither
Landlord nor any agent of Landlord has made any representation or warranty with
respect to the Premises or the Project or with respect to the suitability of
either for the conduct of Tenant's business.  The taking of possession of the
Premises by Tenant shall conclusively establish that the Premises and the
Project were in satisfactory condition at such time.

          (a) Tenant shall make no alterations, additions or improvements in or
to the Premises without Landlord's prior written consent, which consent shall
not be unreasonably withheld, delayed or conditioned, and then only by
contractors or mechanics reasonably approved by Landlord.  Tenant agrees that
there shall be no construction or partitions or other obstructions which might
interfere with Landlord's free access to mechanical installations or service
facilities of the Building or Project or interfere with the moving of Landlord's
equipment to or from the enclosures containing said installations or facilities.
All such work shall be done at such times and in such manner as Landlord may
reasonably designate from time to time. Tenant covenants and agrees
that all work done by Tenant shall be performed in full compliance with all
laws, rules, orders, ordinances,

                                       8
<PAGE>

regulations and requirements of all governmental agencies, offices, and boards
having jurisdiction, and in full compliance with the rules, regulations and
requirements of the Insurance Service Offices formerly known as the Pacific Fire
Rating Bureau, and of any similar body. Before commencing any work, Tenant shall
give Landlord at least ten days written notice of the proposed commencement of
such work and shall, if required by Landlord, secure at Tenant's own cost and
expense, a completion and lien indemnity bond, reasonably satisfactory to
Landlord, for said work. Tenant further covenants and agrees that any mechanic's
lien filed against the Premises or against the Building or Project for work
claimed to have been done for, or materials claimed to have been furnished to,
Tenant will be discharged by Tenant, by bond or otherwise, within thirty
(30) days after Landlord has notified Tenant in writing of the filing thereof,
at the cost and expense of Tenant. All alterations, additions or improvements
upon the Premises made by either party, including (without limiting the
generality of the foregoing) all wallcovering, built-in cabinet work, paneling
and the like, shall, unless Landlord elects otherwise, become the property of
Landlord, and shall remain upon, and be surrendered with the Premises, as a part
thereof, at the end of the term hereof, except that Landlord may, by written
notice to Tenant, given to Tenant at the time that Landlord grants its consent
to any alterations, additions or improvements, specify that Tenant shall be
required to remove such alterations, additions or improvements at the expiration
or sooner termination of this Lease, and in such event Tenant shall repair all
damage resulting from such removal or, at Landlord's option, shall pay to
Landlord all reasonable costs arising from such removal.

          (b) All articles of personal property and all business and trade
fixtures, machinery and equipment, furniture and movable partitions owned by
Tenant or installed by Tenant at its expense in the Premises shall be and remain
the property of Tenant and may be removed by Tenant at any time during the lease
term. If Tenant shall fail to remove all of its effects from the Premises upon
termination of this Lease for any cause whatsoever (other than Landlord's acts),
Landlord may, at its option, remove the same in any reasonable and prudent
manner that Landlord shall choose, and store said effects without liability to
Tenant for loss thereof. In such event, Tenant agrees to pay Landlord upon
demand any and all reasonable and actual expenses incurred in such removal,
including court costs and attorneys' fees and storage charges on such effects
for any length of time that the same shall be in Landlord's possession. Landlord
may, at its option, with notice, sell said effects, or any of the same, at
private sale and without legal process, for such price as Landlord may obtain
and apply the proceeds of such sale upon any amounts due under this Lease from
Tenant to Landlord and upon the expense incident to the removal and sale of said
effects.

expense.  Landlord shall also repair and maintain the basic plumbing, elevators,
life safety systems and other building systems, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, and
perform roof repair and maintenance to the Premises; the cost of such repairs
and maintenance shall be included in Direct Expenses as provided in Article 4.
Landlord shall not be liable for any failure to make any such repairs or to
perform any maintenance unless such failure shall persist for an unreasonable
time after written notice of the need of such repairs or maintenance is given to
Landlord by Tenant. Except as provided in Article 21 hereof, there shall be no
abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business arising from the making of any repairs,
alterations or improvements in or to any portion of the Building, Project or the
Premises or in or to fixtures, appurtenances and equipment therein. Tenant

protection from such liens.  If any such liens are filed, Landlord may, without
waiving its rights and remedies based on such breach of Tenant and without
releasing Tenant from any of its obligations, cause such liens to be released by
any means it shall deem proper, including payments in satisfaction of the claim
giving rise to such lien.  Tenant shall pay to Landlord at once, upon notice by
Landlord, any sum paid by Landlord to remove such liens, together with interest
at the maximum rate per annum permitted by law from the date of such payment by
Landlord.

Premises to prospective purchasers or tenants, to post notices of
nonresponsibility, to alter, improve or repair the Premises or any other portion
of the Building or Project, all without being deemed guilty of any eviction of
Tenant and without abatement of rent. Except for emergencies and regularly
scheduled janitorial services, Landlord shall provide Tenant with reasonable
prior notice of Landlord's intended entry.  Landlord may, in order to carry out
any of the foregoing purposes, erect scaffolding and other necessary
structures where reasonably required by the character of the work to be

little as is reasonably practicable.   Tenant hereby waives any claim for

said doors in an emergency in order to obtain entry to the Premises.  Any entry
to the Premises obtained by Landlord by any of said means, or otherwise, shall
not be construed or deemed to be a forcible or unlawful entry into the Premises,
or any eviction of Tenant from the Premises or any portion thereof. Any damage
to the Premises caused on account thereof shall be paid by Landlord. It is
understood and agreed that no provision of this Lease shall be construed as

entitled to any abatement or reduction of rent by reason of such failure, no
eviction of Tenant shall result from such failure and Tenant shall not be
relieved from the performance of any covenant or agreement in this Lease because
of such failure.  In the event of any failure, stoppage or interruption thereof,
Landlord shall diligently attempt to resume service promptly.

In such case, notwithstanding any other provisions of this Lease, Landlord, in
addition to any and all rights and remedies allowed by law or equity, shall,
upon such termination, be entitled to recover damages in the amount provided in
Paragraph 23(b) hereof. Neither Tenant nor any person claiming through or under

statute or rule of law in effect at the time when, and governing the proceedings
in which, such damages are to be proved; whether or not such amount is greater,
equal to, or less than the amount of damages recoverable under the provisions of

claims arising from Tenant's use of the Premises or the conduct of its business
or from any activity, work, or thing done, permitted or suffered by Tenant in or
about the Premises except to the extent arising from the gross negligence or

indemnify, defend and hold Landlord harmless from all claims arising from any
breach or default in the performance of any obligation to be performed by Tenant
under the terms of this Lease, or arising from any act, neglect, fault or
omission of Tenant or of its agents or employees, and from and against all
costs, attorneys' fees, expenses and liabilities incurred in or about such claim
or any action or proceeding brought thereon.  In case any action or proceeding
shall be brought against Landlord by reason  of any such claim, Tenant upon
notice from Landlord shall defend the same at Tenant's expense by counsel
approved in writing by Landlord.  Tenant, as a material part of the
consideration to Landlord, hereby assumes all risk of damage to property or
injury to person in, upon or about the Premises from any cause whatsoever except
that which is caused by the failure of Landlord to observe any of the terms and
conditions of this Lease where such failure has persisted for an unreasonable
period of time after written notice of such failure.  Tenant hereby waives all
its claims in respect thereof against Landlord.

to property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water or rain which may leak from any part of the Project or from
the pipes, appliances or plumbing work therein or from the roof, street or sub-
surface or from any other place or resulting from dampness or from any other
cause whatsoever. Landlord or its agents shall not be liable for interference
with light or other incorporeal hereditaments. Tenant shall give prompt notice
to Landlord in case of fire or accidents in the Premises or in the Project or of
defects therein or in the fixtures or equipment.

                               ------------------

          (a)  Tenant shall, during the term hereof and any other period of
occupancy, at its sole cost and expense, keep in full force and effect the
following insurance:

               (i)   Standard form property insurance insuring against the
perils of fire, extended coverage, vandalism, malicious mischief, special
extended coverage ("All-Risk") and sprinkler leakage. This insurance policy
shall be upon all property owned by Tenant, for which Tenant is legally liable
or that was installed at Tenant's expense, and which is located in the Project
including, without limitation, furniture, fittings, installations, fixtures
(other than Tenant improvements installed by Landlord), and any other personal
property in an amount not less than ninety percent of the full replacement cost
thereof. Such policy shall name Landlord and any mortgagees of Landlord as
additional insured parties, as their respective interests may appear.

               (ii)  Commercial General Liability Insurance insuring Tenant
against any liability arising out of the lease, use, occupancy or maintenance of
the Premises and all areas appurtenant thereto. Such insurance shall be in the
amount of $2,000,000 Combined Single Limit for injury to, or death of one or
more persons in an occurrence, and for damage to tangible property (including
loss of use) in an occurrence. The policy shall insure the hazards of premises
and operation, contractual liability (covering the Indemnity contained in
Paragraph 18 hereof) and shall (1) name Landlord as an additional insured, and
(2) contain a cross liability provision, and (3) contain a provision that "the
insurance provided the Landlord hereunder shall be primary and non-contributing
with any other insurance available to the Landlord."

               (iii)  Workers' Compensation and Employer's Liability insurance
(as required by state law).

               (iv)   Any other form or forms of insurance as Tenant or Landlord
or any mortgagees of Landlord may reasonably require from time to time in form,
in amounts and for insurance risks against which a prudent tenant would protect
itself; provided that such other insurance is warranted due to a substantial
change in the nature of Tenant's operations at the Premises and

                                      13
<PAGE>

the increased risks associated therewith or due to the total amount of any
claims paid on Tenant's insurance policies in the prior twelve (12) month
period, or such insurance is customarily required for similar uses by owners of
comparable buildings in Pleasanton, California.

          (b)  All policies shall be written in a form satisfactory to Landlord
and shall be taken out with insurance companies holding a General Policyholders
Rating of "A" and a Financial Rating of "X" or better, as set forth in the most
current issue of Bests Insurance Guide.  Within thirty days after the
execution of this Lease, Tenant shall deliver to Landlord
certificates evidencing the existence of the amounts and forms of coverage
satisfactory to Landlord.  No such policy shall be cancelable or reducible in
coverage except after thirty days prior written notice to Landlord.  Tenant
shall, within ten days prior to the expiration of such policies, furnish
Landlord with a new certificate of insurance evidencing the renewal thereof, or
within ten (10) days after written notice Landlord may order such insurance and
charge the cost thereof to Tenant as additional rent. If Landlord obtains any
insurance that is the responsibility of Tenant under this section, Landlord
shall deliver to Tenant a written statement setting forth the cost of any such
insurance and showing in reasonable detail the manner in which it has been
computed.

                             ---------------------

          (a)  In the event the Project and/or the Premises is damaged by fire
or other perils covered by Landlord's insurance, Landlord shall have the
following rights and obligations:

               (i)  In the event of total destruction, at Landlord's option, as
soon as reasonably possible thereafter, commence repair, reconstruction and
restoration of the Project and/or the Premises and prosecute the same diligently
to completion, in which event this Lease shall remain in full force and effect;
or within ninety days after such damage, elect not to so repair, reconstruct or
restore the Project and/or the Premises, in which event this Lease shall
terminate. In either event, Landlord shall give Tenant written notice of its
intention within said ninety day period. In the event Landlord elects not to
restore the Project and/or the Premises, this Lease shall be deemed to have
terminated as of the date of such total destruction.

               (ii) In the event of a partial destruction of the Project and/or
the Premises, to an extent not exceeding twenty-five percent of the full
insurable value thereof, and if the damage thereto is such that the Project
and/or the Premises may be repaired, reconstructed or restored within a period
of ninety days from the date of the happening of such casualty and if Landlord
will receive insurance proceeds sufficient to cover at least ninety-five percent
(95%) of the cost of such repairs, then Landlord shall commence and proceed
diligently with the work of repair, reconstruction and restoration and this
Lease shall continue in full force and effect. If such work of repair,
reconstruction and restoration shall require a period longer than ninety days or
exceeds twenty-five percent of the full insurable value thereof, or if said
insurance proceeds will not be sufficient to cover the cost of such repairs,
then Landlord either may elect to so repair, reconstruct or restore and the
Lease shall continue in full force and effect or Landlord may elect not to
repair, reconstruct or restore and the Lease shall then terminate. Under any of
the conditions of this Subparagraph 21(a)(ii), Landlord shall give written
notice to Tenant of its intention within said ninety day period. In the event
Landlord elects

                                      14
<PAGE>

not to restore the Project and/or the Premises, this Lease shall be deemed to
have terminated as of the date of such partial destruction.

          (b) Upon any termination of this Lease under any of  the provisions of
this Article 21, the parties shall be released without further obligation to the
other from the date possession of the Premises is surrendered to Landlord except
for items which have therefore accrued and are then unpaid.

          (c) In the event of repair, reconstruction and restoration by Landlord
as herein provided, the rental payable under this Lease shall be abated
proportionately with the degree to which Tenant's use of the Premises is
impaired during the period of such repair, reconstruction or restoration.
Tenant shall not be entitled to any compensation or damages for loss in the use
of the whole or any part of the Premises and/or any inconvenience or annoyance
occasioned by such damage, repair, reconstruction or restoration.

          (d) Tenant shall not be released from any of its obligations under
this Lease except to the extent and upon the conditions expressly stated in this
Article 21.  Notwithstanding anything to the contrary contained in this Article
21, if Landlord is delayed or prevented from repairing or restoring the damaged
Premises within one year after the occurrence of such damage or destruction by
reason of acts of God, war, governmental restrictions, inability to procure the
necessary labor or materials, or other cause beyond the control of Landlord,
Landlord shall be relieved of its obligation to make such repairs or restoration
and Tenant shall be released from its obligation under this Lease as of the end
of said one year period.

          (e) If damage, as defined and described in paragraph 21(a) above,
is due to any cause other than fire or other peril covered by extended coverage
insurance, Landlord may elect to terminate this Lease.

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

          (g) Notwithstanding anything to the contrary contained in this Article
21, Landlord shall not have any obligation whatsoever to repair, reconstruct or
restore the Premises when the damage resulting from any casualty covered under
this Article 21 occurs during the last twelve months of the term of this Lease
or any extension hereof.

          (h) The provisions of California Civil Code 1932, Subsection 2, and
1933, Subsection 4, which permit termination of a lease upon destruction of the
Leased Premises, are hereby waived by Tenant; and the provisions of this Article
shall govern in case of such destruction.

eminent domain, or sold to prevent such taking, either party shall have the
right to terminate this Lease effective as of the date possession is required to
be surrendered to said authority. Tenant shall not assert any claim against
Landlord or the taking authority for any compensation because of such taking,
and Landlord shall be entitled to receive the entire amount of any award without
deduction for any estate or interest of Tenant. In the event the amount of
property or the type of estate taken shall not substantially interfere with the
conduct of Tenant's business, Landlord shall be entitled to the entire amount of
the award without deduction for any estate or interest of Tenant, Landlord shall
restore the Premises to substantially their same condition prior to such partial
taking, and a proportionate allowance shall be made to Tenant for the rent
corresponding to the time during which, and to the part of the Premises of
which, Tenant shall be so deprived on account of such taking and restoration.
Nothing contained in this Paragraph shall be deemed to give Landlord any
interest in any award made to Tenant for the taking of personal property and
fixtures belonging to Tenant.

                             ---------------------

          (a)  The occurrence of any one or more of the following events shall
constitute a default hereunder by Tenant:

               (i)   The failure by Tenant to make any payment of rent or
additional rent or any other payment required to be made by Tenant hereunder, as
and when due, where such failure shall continue for a period of ten (10)
business days after written notice thereof from Landlord to Tenant; provided
however, that any such notice shall be in lieu of, and not in addition to, any
notice required under California Code of Civil Procedure Section 1161 regarding
unlawful detainer actions.

               (ii)  The failure by Tenant to observe or perform any of the
express or implied covenants or provisions of this Lease to be observed or
performed by Tenant, other than as specified in Subparagraph 23(a)(i)
above, where such failure shall continue for a period of thirty (30) days after
written notice thereof from Landlord to Tenant. Any such notice shall be in lieu
of, and not in addition to, any notice required under California Code of Civil
Procedure Section 1161 regarding unlawful detainer actions. If the nature of
Tenant's default is such that more than thirty (30) days are reasonably
required for its cure, then Tenant shall not be deemed to be in default if
Tenant shall commence such cure within said thirty-day period and thereafter
diligently prosecute such cure to completion.

               (iii) (1)   The making by Tenant of any general assignment for
the benefit of creditors; (2) the filing by or against Tenant of a petition to
have Tenant adjudged a bankrupt or a petition for reorganization or arrangement
under any law relating to bankruptcy (unless, in the case of a petition filed
against Tenant, the same is dismissed within thirty days); (3) the appointment
of a

                                      16
<PAGE>

trustee or receiver to take possession of substantially all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease, where possession
is not restored to Tenant within thirty days; or (4) the attachment, execution
or other judicial seizure of substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease where such seizure is not
discharged within thirty days.

          (b)  In the event of any such default by Tenant which continues beyond
the expiration of any applicable cure period provided for herein, in addition to
any other remedies available to Landlord at law or in equity, Landlord shall
have the immediate option to terminate this Lease and all rights of Tenant
hereunder.  In the event that Landlord shall elect to so terminate this Lease
then Landlord may recover from Tenant:

               (i)   the worth at the time of award of any unpaid rent which had
been earned at the time of such termination; plus

               (ii)  the worth at the time of award of the amount by which the
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; plus

               (iii) the worth at the time of award of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided; plus

               (iv)  any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform Tenant's
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom.

As used in Subparagraph 23(b)(i) and (ii) above, the "worth at the time of
award" is computed by allowing interest at the maximum rate permitted by law.
As used in Subparagraph 23(b)(iii) above, the "worth at the time of award" is
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award plus one percent.

          (d)  All rights, options and remedies contained in this Lease shall be
constructed and held to be cumulative, and no one of them shall be exclusive of
the other, and either party shall have the right to pursue any one or all of
such remedies or any other remedy or relief which may be provided by law,
whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any rent or other
payments due hereunder or any omission by Landlord to take any action on account
of such default if such default persists or is repeated, and no express waiver
shall affect defaults other than as specified in said waiver.

<PAGE>

The consent or approval of Landlord to or of any act by Tenant requiring
Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent or approval to or of any subsequent similar acts
by Tenant.

          (e) The chronic delinquency by Tenant in the payment of Basic Rent or
any other payments required to be paid by Tenant under this Lease shall
constitute a default hereunder by Tenant.  "Chronic delinquency" shall mean
failure by Tenant to pay Basic Rent, or any other payments required to be paid
by Tenant under this Lease within ten (10) business days after written notice
thereof (together with appropriate invoices or other backup documentation for
any non-rent payments due from Tenant) for any three (3) occasions (consecutive
or non-consecutive) during any twelve (12) month period. In the event of a
chronic delinquency, Landlord shall have the right, at Landlord's option, to
require that Basic Rent be paid by Tenant quarterly, in advance.

                           ASSIGNMENT AND SUBLETTING
                           -------------------------

          (a) Tenant shall not voluntarily assign or encumber its interest in
this Lease or in the Premises, or sublease all or any part of the Premises, or
allow any other person or entity to occupy or use all or any part of the
Premises, without first obtaining Landlord's prior written consent which consent
shall not be unreasonably withheld, delayed or conditioned.  Any assignment,
encumbrance or sublease without Landlord's prior written consent shall be
voidable, at Landlord's election, and shall constitute a default.  No consent to
assignment, encumbrance, or sublease shall constitute a further waiver of the
provisions of this paragraph. Tenant shall notify Landlord in writing of
Tenant's intent to sublease, encumber or assign this Lease and Landlord shall,
within ten (10) business days of receipt of such written notice, elect one of
the following:

              (i)   Consent to such proposed assignment, encumbrance or
sublease;

              (ii)  Refuse such consent, which refusal shall be on reasonable
grounds; or

              (iii) Elect to terminate this Lease.

          (b) As a condition for granting its consent to any assignment,
encumbrance or sublease, thirty (30) days prior to any anticipated assignment or
sublease Tenant shall give Landlord written notice (the "Assignment Notice"),
which shall set forth the name, address and business of the proposed assignee or
sublessee, information (including references) concerning the character,
ownership, and financial condition of the proposed assignee or sublessee, and
the Assignment Date, any ownership or commercial relationship between Tenant and
the proposed assignee or sublessee, and the consideration of all other material
terms and conditions of the proposed assignment or sublease, all in such detail
as Landlord shall reasonably require. If Landlord requests reasonable additional
detail, upon receipt of the Assignment Notice, such notice shall not be deemed
to have been received until Landlord receives such additional detail, and
Landlord may withhold consent to any assignment or sublease until such
additional detail is provided to it. Further, Landlord may require that the
sublessee

                                      18
<PAGE>

or assignee remit directly to Landlord on a monthly basis, all monies due to
Tenant by said assignee or sublessee.

          (c) The consent by Landlord to any assignment or subletting shall not
be construed as relieving Tenant or any assignee of this Lease or sublessee of
the Premises from obtaining the express written consent of Landlord to any
further assignment or subletting or as releasing Tenant or any assignee or
sublessee of Tenant from any liability or obligation hereunder whether or not
then accrued.  In the event Landlord shall consent to an assignment or sublease,
Tenant shall pay Landlord as Additional Rent a reasonable attorneys' and
administrative fee not to exceed $500 for costs incurred in connection with
evaluating the Assignment Notice.  This section shall be fully applicable to all
further sales, hypothecations, transfers, assignments and subleases of any
portion of the Premises by any successor or assignee of Tenant, or any sublessee
of the Premises.

          (d) As used in this section, the subletting of substantially all of
the Premises for substantially all of the remaining term of this Lease shall be
deemed an assignment rather than a sublease. Notwithstanding the foregoing,
Landlord's consent shall not be required for an assignment, sale or
transfer to an affiliate of Tenant, any entity into which Tenant is merged, with
which Tenant is consolidated or which acquires all or substantially all of the
assets or stock of Tenant, provided that the assignee first executes,
acknowledges and delivers to Landlord an agreement whereby the assignee agrees
to be bound by all of the covenants and agreements in this Lease which Tenant
has agreed to keep, observe or perform, that the assignee agrees that the
provisions of this section shall be binding upon it as if it were the original
Tenant hereunder and that the assignee shall have a net worth (determined in
accordance with generally accepted accounting principles consistently applied)
immediately after such assignment which is at least equal to the net worth (as
so determined) of Tenant at the commencement of this Lease.

          (e) Except as provided above, Landlord's consent to any sublease shall
not be unreasonably withheld.  A condition to such consent shall be delivery by
Tenant to Landlord of a true copy of any such sublease.  If for any proposed
assignment or sublease Tenant receives rent or other consideration, either
initially or over the term of the assignment or sublease, in excess of the rent
called for hereunder, or, in case of the sublease of a portion of the Premises,
in excess of such rent fairly allocable to such portion, after appropriate
adjustments to assure that all other payments called for hereunder are taken
into account and after Tenant has first recovered any reasonable and customary
brokerage commission, reasonable attorneys' fees, and advertising costs paid by
Tenant in connection with the assignment or sublease, Tenant shall pay to
Landlord as additional rent hereunder one-half (1/2) of the excess of each such
payment of rent or other consideration received by Tenant promptly after its
receipt. Landlord's waiver or consent to any assignment or subletting shall not
relieve Tenant from any obligation under this lease. The parties intend that the
preceding sentence shall not apply to any sublease rentals respecting a portion
of the Premises that during the entire term of this Lease was not occupied by
Tenant for its own use, but was always subleased by Tenant and/or kept vacant.

          Without the necessity of any additional document being executed by
Tenant for the purpose of effecting a subordination, and at the election of
Landlord or any mortgagee with a lien on the Project or any ground lessor with
respect to the Project, this Lease shall be subject and subordinate at all times
to:

               (i)   All ground leases or underlying leases which may now exist
or hereafter be executed affecting the Project or the land upon which the
Project is situated or both,

               (ii)  The lien of any mortgage or deed of trust which may now
exist or hereafter be executed in any amount for which the Project, land, ground
leases or underlying leases, or Landlord's interest or estate in any of said
items is specified as security, so long as the holder of any such ground or
underlying lease, mortgage or deed of trust executes and delivers to Tenant a
non-disturbance agreement which provides that in the event of any termination of
such lease or foreclosure of any such mortgage or deed of trust this Lease shall
not be terminated so long as Tenant is not in default hereunder. Notwithstanding
the foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying leases or any such liens to
the Lease. In the event that any ground lease or underlying lease terminates for
any reason or any mortgage or deed of trust is foreclosed or a conveyance in
lieu of foreclosure is made for any reason, Tenant shall, notwithstanding any
subordination, attorn to and become the Tenant of the successor in interest to
Landlord. Tenant covenants and agrees to execute and deliver, upon demand by
Landlord and in the form requested by Landlord, any additional documents
evidencing the priority or subordination of this Lease with respect to any such
ground leases or underlying leases or the lien of any such mortgage or deed of
trust so long as, in the event of any subordination, such document(s) contain
the non-disturbance provisions stated above.

               (iii) The CC&R's as described in Article 6.

          (a)  Within ten days following any written request which Landlord may
make from time to time, Tenant shall execute and deliver to Landlord a statement
prepared initially by Landlord and confirming:

               (i)   The date of commencement of this Lease;

               (ii)  The fact that this Lease is unmodified and in full force
and effect (or, if there have been modifications hereto, that this Lease is in
full force and effect, and stating the date and nature of such modifications);

               (iii) The date to which the rental and other sums payable under
this Lease have been paid;

this Lease by either Landlord or Tenant except as specified in Tenant's
statement; and

               (v)   Such other matters  reasonably requested by Landlord.
Landlord and Tenant intend that any statement delivered pursuant to this Article
26 may be relied upon by any mortgagee, beneficiary, purchaser or prospective
purchaser of the Building or Project or any interest therein.

          (b)  Tenant's failure to deliver such statement to Landlord within
five (5) days after Landlord has delivered a second notice to Tenant requesting
completion of such statement shall be conclusive upon Tenant:

               (i)   That this Lease is in full force and effect, without
modification

               (ii)  That there are no uncured defaults in Landlord's
performance, and

               (iii) That not more than one month's rental has been paid in
advance.

          Landlord shall provide for Tenant the opportunity to have Tenant's
name placed upon the Building lobby directory sign, at Tenant's entrance to the
Premises, at the building monument sign at the street, and at the exterior
"tombstone" sign at the building entrance.  Tenant shall have exclusive use of
the monument sign as shown on Exhibit A-2.  Tenant shall have no right to
maintain any other Tenant identification sign in any other location in, on or
about the Premises, the Building, the Project, or Bernal Corporate Park and
shall not display or erect any Tenant identification sign, display or other
advertising material within the Premises that is visible from the exterior of
the Building. The size, design, color and other physical aspects of the Tenant
identification sign shall be subject to Landlord's written reasonable approval
prior to installation. The cost of the installation of the sign, and its
maintenance and removal expense, shall be at Tenant's sole expense. If Tenant
fails to maintain its sign or if Tenant fails to remove its sign upon
termination of this Lease, Landlord may do so at Tenant's expense and Tenant's
reimbursement to Landlord for such amounts shall be deemed additional rent. All
signs shall comply with rules and regulations set forth by Landlord as may be
modified from time to time.

          The voluntary or other surrender of this Lease by Tenant, or a mutual

          All covenants and agreements to be performed by Tenant under any of

for thirty (30) days after written notice thereof by Landlord, Landlord may,
without waiving or releasing Tenant from obligations of Tenant, but shall not be
obligated to, make any such payment or perform any such other act to be made or
performed by Tenant. All sums so paid by Landlord and all necessary incidental
costs together with interest thereon at the maximum rate permissible by law,
from the date of such payment by Landlord, shall be payable to Landlord on
demand. Tenant covenants to pay any such sums and Landlord shall have (in
addition to any other right or remedy of Landlord) all rights and remedies in
the event of the non-payment thereof by Tenant as are set forth in Article 23
hereof.

          In the event of any default on the part of Landlord, Tenant will give
notice by registered or certified mail to any beneficiary of a deed of trust or
mortgage covering the Premises whose address shall have been furnished to
Tenant, and shall offer such beneficiary or mortgagee a reasonable opportunity
to cure the default, including time to obtain possession of the Premises by
power of sale or a judicial foreclosure, if such should prove necessary to
effect a cure.

          The term "Landlord", as used in this Lease, so far as covenants or
obligations on the part of Landlord are concerned, shall be limited to mean and
include only the owner or owners, at the time in question, of the fee title of
the Premises or the lessees under any ground lease, if any.  In the event of any
transfer, assignment or other conveyance or transfers of any such title,
Landlord herein named (and in case of any subsequent transfers or conveyances,
the then grantor) shall be automatically freed and relieved from and after the
date of such transfer, assignment or conveyance of all liability as respects the
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed.  Without further agreement, the
transferee of such title shall be deemed to have assumed and agreed to observe
and perform any and all obligations of Landlord hereunder, during its ownership
of the Premises.  Landlord may transfer its interest in the Premises without the
consent of Tenant and such transfer or subsequent transfer shall not be deemed a
violation on Landlord's part of any of the terms and conditions of this Lease.

          The waiver by either Landlord or Tenant of any breach of any term,
covenant or condition herein contained shall not be deemed to be a waiver of any
subsequent breach of the same or any other term, covenant or condition herein
contained, nor shall any custom or practice which may grow up between the
parties in the administration of the terms hereof be deemed a waiver of or in
any way affect the right of either Landlord or Tenant to insist upon the
performance by the other in strict accordance with said terms. The subsequent
acceptance of rent hereunder by Landlord shall not be deemed to be a waiver of
any preceding breach by Tenant or any term, covenant or condition 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 at the time of
acceptance of such rent.

If, in Landlord's reasonable business judgment, it becomes necessary, Landlord
shall exercise due diligence to cause the creation of cross-parking easements
and such other agreements as are necessary to permit Tenant, its employees and
invitees to use parking spaces on the properties and buildings of Bernal
Corporate Park, which are separate legal parcels from the Project.  Tenant
acknowledges that other tenants of the Project and the tenants of the other
buildings, their employees and invitees, may be given the right to park at the
Project.  All parking shall be provided to Tenant at no charge during the term
of this Lease; provided, however, that if the City of Pleasanton or any other
governmental entity with jurisdiction imposes any fees or charges related to
parking, such fees or charges may be included in Direct Expenses and billed to
Tenant as provided in Article 4.

withhold, delay or defer its consent thereto, provided that such modifications

(the "Premises") more particularly described in EXHIBIT A attached to the Lease.
                                                ---------

     B.  In order to induce Tenant to enter into the Lease (which is hereby
incorporated by reference to the extent that the provisions of this Work Letter
Agreement may apply hereto) and in consideration of the mutual covenants
hereinafter contained, Landlord and Tenant hereby agree as follows:

          1.   COMPLETION SCHEDULE

deliver to Tenant, for Tenant's review and approval, a schedule (the "Work
Schedule") setting forth a timetable for the planning and completion of the
installation of the Tenant Improvements to be constructed in the Premises.  The
Work Schedule shall set forth each of the various items of work to be done by or
approval to be given by Landlord and Tenant in connection with the completion of
the Tenant Improvements.  Such schedule shall be submitted to Tenant for its
approval and, upon approval by both Landlord and Tenant, such schedule shall
become the basis for completing the Tenant Improvement Work.  If Tenant shall
fail to approve the Work Schedule, as it may be modified after discussions
between Landlord and Tenant, within five working days the Landlord may presume
that it has been accepted.

          2.   TENANT IMPROVEMENTS

          Reference herein to "Tenant Improvements" shall include all work to be
done in the Premises pursuant to the Tenant Improvement Plans described in
Paragraph 3 below, including but not limited to partitioning, doors, ceilings,
floor coverings, finishes, (including paint and wallcovering) electrical,

<PAGE>

          Immediately after the execution of this Lease, Tenant agrees to meet
with Landlord's architect and/or space planner for the purpose of preparing a
space plan for the layout of the Premises.  Based upon such space plan,
Landlord's architect shall prepare final working drawings and specifications may
be referred to herein as the "Tenant Improvement Plans."

     4.   FINAL PRICING AND DRAWING SCHEDULE

          After the preparation of the space plan and after Tenant's written
approval thereof, in accordance with the Work Schedule, Landlord shall cause its
architect to prepare and submit to Tenant the final working drawings and
specifications referred to in Paragraph 3 hereof.  Such working drawings shall
be approved by Landlord and Tenant in accordance with the Work Schedule and
shall thereafter be submitted to the appropriate governmental body for plan
checking and a building permit.  Concurrent with the plan checking, Landlord
shall have prepared a final pricing for Tenant's approval, taking into account
any modifications which may be required to reflect changes in the plans and
specifications required by the City or County in which the Premises are located.
After final approval of the working drawings, no further changes to Tenant
Improvement Plans may be made without the prior written approval from both
Landlord and Tenant, and then only after agreement by Tenant to pay any excess
costs resulting from such changes.

          After the Tenant Improvement Plans have been prepared and approved,
the final pricing has been approved by both Landlord and Tenant in writing, and
a building permit for the tenant Improvements has been issued, Landlord shall
enter into a construction contract with its contractor for the installation of
the Tenant Improvements in accordance with the Tenant Improvement Plans.
Landlord shall supervise the completion of such work and shall use its best
efforts to secure completion of the work in accordance with the Work Schedule.

          The following Standards for Utilities and Services are in effect.
Landlord reserves the right to adopt nondiscriminatory modifications and
additions hereto:

          Landlord shall:

          (a)  On Monday through Friday, except holidays, from 7 A.M. to 6 P.M.
(and other times for a reasonable additional charge to be fixed by Landlord),
ventilate the Premises and furnish air conditioning or heating on such days and
hours, when in the reasonable judgment of Landlord, in accordance with prudent
practices for comparable Class A office buildings in Pleasanton, it may be
required for the comfortable occupancy of the Premises.  The air conditioning
system achieves maximum cooling when the window coverings are closed.  Landlord
shall not be responsible for room temperatures if to the extent affected where
Tenant does not keep all window coverings in the Premises closed.  Tenant agrees
to cooperate fully at all times with Landlord, and to abide by all regulations
and requirements which Landlord may prescribe for the proper function and
protection of said air conditioning system. Tenant agrees not to connect any
apparatus, device, conduit or pipe to the Building chilled and hot water air
conditioning supply lines. Tenant further agrees that neither Tenant nor its
servants, employees, agents, visitors, licensees or contractors shall at any
time enter mechanical installations or facilities of the Building or adjust,
tamper with, touch or otherwise in any manner affect said installations or
facilities. The cost of maintenance and service calls to adjust and regulate the
air conditioning system shall be charged to Tenant if the need for maintenance
work results from either Tenant's adjustment of room thermostats or Tenant's
failure to comply with its obligations under this section, including keeping
window coverings closed as needed. Such work shall be charged at hourly rates
equal to then current journeymen's wages for air conditioning mechanics.

          (b)  Landlord shall furnish to Tenant after-hours heating and air
conditioning at the rate of $20.00 per hour (two-hour minimum charge) for such
after-hours use.  If the actual cost to Landlord of providing such after-hours
heating and air-conditioning increases at any time during the term of this
Lease, Landlord shall have the right to increase the hourly rate charged by
Landlord for such after-hours usage to the extent such costs are increased upon
at least 10 days prior notice to Tenant. Landlord shall bill Tenant monthly for
such after-hours usage. If such charges are billed to Tenant separately from
rent, then Tenant shall pay such charges to Landlord, as additional rent, within
thirty (30) days after receipt of Landlord's statement of such charges.

          (c)  Landlord shall furnish to the Premises, during the usual business
hours on business days, electric current sufficient for normal office use.
Tenant agrees, should its electrical installation or electrical consumption be
in excess of the aforesaid quantity or extend beyond normal

                                   EXHIBIT C
                                   ---------

business hours, to reimburse Landlord monthly for the measured consumption at
the average cost per kilowatt hour charged to the Building during the period.
If a separate meter is not installed at Tenant's cost, such excess cost will be
established by an estimate agreed upon by Landlord and Tenant, and if the
parties fail to agree, as established by an independent licensed engineer. Said
estimates to be reviewed and adjusted quarterly. Tenant agrees not to use any
apparatus or device in, or upon, or about the premises which may in any way
increase the amount of such services usually furnished or supplied to said
Premises, and Tenant further agrees not to connect any apparatus or device with
wires, conduits or pipes, or other means by which such services are supplied,
for the purpose of using additional or unusual amounts of such services without
written consent of Landlord. Should Tenant use the same to excess, the refusal
on the part of Tenant to pay upon demand of Landlord the amount established by
Landlord for such excess charge shall constitute a breach of the obligation to
pay rent under this Lease and shall entitle Landlord to the rights therein
granted for such breach. At all times Tenant's use of electric current shall
never exceed the capacity of the feeders to the Building or the risers or wiring
installation and Tenants shall not install or use or permit the installation or
use of any computer, larger than personal computer, without the prior written
consent of Landlord, which consent shall not be unreasonably withheld, delayed
or conditioned.

          (d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses or consumes water for any purposes
in addition to ordinary drinking and lavatory purposes of which fact Tenant
constitutes Landlord to be the sole judge, Landlord may install a water meter
and thereby measure Tenant's water consumption for all purposes.  Tenant shall
pay Landlord for the cost of the meter and the cost of the installation thereof
and throughout the duration of Tenant's occupancy, Tenant shall keep said meter
and installation equipment in good working order and repair at Tenant's own cost
and expense, in default of which Landlord may cause such meter and equipment to
be replaced or repaired and collect the cost thereof from Tenant.  Tenant agrees
to pay for water consumed, as shown on said meter, as and when bills are
rendered, and on default in making such payment, Landlord may pay such charges
and collect the same from Tenant.  Any such costs or expenses incurred, or
payments made by Landlord for any of the reasons or purposes hereinabove stated
shall be deemed to be additional rent payable by Tenant and collectible by
Landlord as such.  Landlord will provide water to the kitchen for standard
kitchen uses (i.e. cleaning dishes and making coffee) and to the wet bar in the
board room for standard office environment uses (i.e. making coffee or rinsing
dishes).

          (e) Provide janitor service to the Premises, provided the same are
kept reasonably in order by Tenant, and if to be kept clean by Tenant, no one
other than persons reasonably approved by Landlord shall be permitted to enter
the Premises for such purposes.  If the Premises are not used exclusively as
offices, they shall be kept clean and in order by Tenant, at Tenant's expense,
and to the satisfaction of Landlord, and by persons approved by Landlord.
Tenant shall pay to Landlord the cost

of removal of any of Tenant's refuse and rubbish, to the extent that the same
exceeds the refuse and rubbish usually attendant upon the use of the Premises as
offices.

          (f) Landlord reserves the right to stop service of the elevator,
plumbing, ventilation, air conditioning and electric systems, to the extent
necessary, by reason of accident or emergency or for repairs, alterations or
improvements, in the judgment of Landlord desirable or necessary to be made,
until said repairs, alterations or improvements shall have been completed, and
shall further have no responsibility or liability for failure to supply elevator
facilities, plumbing, ventilating, air conditioning or electric service, when
prevented from so doing by strike or accident or by any cause beyond Landlord's
reasonable control, or by laws, rules, orders, ordinances, directions,
regulations or requirements of any federal, state, county or municipal authority
or failure of gas, oil or other suitable fuel supply or inability by exercise of
reasonable diligence to obtain gas, oil or other suitable fuel. It is expressly
understood and agreed that any covenants on Landlord's part to furnish any
service pursuant to any of the terms, covenants, conditions, provisions or
agreements of this Lease, or to perform any act or thing for the benefit of
Tenant, shall not be deemed breached if Landlord is unable to furnish or perform
the same by virtue of a strike or labor trouble or any other cause whatsoever
beyond Landlord's control.

     1.   Except as specifically provided in the Lease to which these Rules and
Regulations are attached, no sign, placard, picture, advertisement, name or
notice shall be installed or displayed on any part of the outside or inside of

entrances, elevators, escalators, or stairways of the Project.  The halls,
passages, exits, entrances, elevators, and stairways are not open to the general

invitees.  Landlord shall in all cases retain the right to control and prevent
access thereto of all persons whose presence in the judgment of Landlord would
be prejudicial to the safety, character, reputation and interest of the Project
and its tenants; provided that nothing herein contained shall be construed to
prevent such access to persons with whom any tenant normally deals in the
ordinary course of its business, unless such persons are engaged in illegal or
unlawful activities.  No tenant and no employee or invitee of any tenant shall
go upon the roof of any building of the Project.

cleaning the same.  Tenant shall not cause any unnecessary labor by carelessness
or indifference to the good order and cleanliness of the Premises.

          responsibility for damage to vehicles is assumed by the parker.

     10.  Loss of theft of parking identification devices from automobiles must
          be reported immediately, and a lost or stolen report must be filed by
          the customer at that time. Landlord has the right to exclude any car
          from the parking facilities that does not have an identification.

     11.  Any parking identification devices reported lost or stolen found on

          reasonable and non-discriminatory rules and regulations for the
          parking facilities as it deems necessary for the operation of the
          parking facilities provided that such rules and regulations do not
          materially diminish Tenant's rights or materially increase Tenant's
          obligations. Landlord may refuse to permit any person who violates
          these rules to park in the parking facilities, and any violation of
          the rules shall subject the car to removal.
