                                VITALSTREAM, INC.
                      2000 STOCK OPTION/STOCK ISSUANCE PLAN

                                   ARTICLE ONE

                               GENERAL PROVISIONS

     I.   PURPOSE OF THE PLAN

          This 2000 Stock Option/Stock Issuance Plan is intended to promote the
interests of VitalStream, Inc., a Delaware corporation, by providing eligible
persons in the Corporation's employ or service with the opportunity to acquire a
proprietary interest, or otherwise increase their proprietary interest, in the
Corporation as an incentive for them to continue in such employ or service.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into two (2) separate equity programs:

                    (i)    the Option Grant Program under which eligible persons
     may, at the discretion of the Plan Administrator, be granted options to
     purchase shares of Common Stock, and

                    (ii)   the Stock Issuance Program under which eligible
     persons may, at the discretion of the Plan Administrator, be issued shares
     of Common Stock directly, either through the immediate purchase of such
     shares or as a bonus for services rendered the Corporation (or any Parent
     or Subsidiary).

          B.   The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   The Plan shall be administered by the Board. However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee. Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

<Page>

          B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options or stock issuances thereunder as it may deem necessary or
advisable. Decisions of the Plan Administrator shall be final and binding on all
parties who have an interest in the Plan or any option grant or stock issuance
thereunder.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Plan are as follows:

                      (i)     Employees,

                      (ii)    non-employee members of the Board or the
     nonemployee members of the board of directors of any Parent or Subsidiary,
     and

                      (iii)   consultants and other independent advisors who
     provide services to the Corporation (or any Parent or Subsidiary).

          B.   The Plan Administrator shall have full authority to determine,
(i) with respect to the grants made under the Option Grant Program, which
eligible persons are to receive the option grants, the time or times when those
grants are to be made, the number of shares to be covered by each such grant,
the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding, and (ii) with
respect to stock issuances made under the Stock Issuance Program, which eligible
persons are to receive such stock issuances, the time or times when those
issuances are to be made, the number of shares to be issued to each Participant,
the vesting schedule (if any) applicable to the issued shares and the
consideration to be paid by the Participant for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Option Grant Program or to effect stock
issuances in accordance with the Stock Issuance Program.

     V.   STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock. The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed 2,000,000
shares.

          B.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant

                                        2
<Page>

provisions of Article Two. Unvested shares issued under the Plan and
subsequently repurchased by the Corporation, at the option exercise or direct
issue price paid per share, pursuant to the Corporation's repurchase rights
under the Plan shall be added back to the number of shares of Common Stock
reserved for issuance under the Plan and shall accordingly be available for
reissuance through one or more subsequent option grants or direct stock
issuances under the Plan.

          C.   Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive. In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                                   ARTICLE TWO

                              OPTION GRANT PROGRAM

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.

               1.   The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                    (i)  The exercise price per share shall not be less than
     eighty-five percent (85%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                    (ii) If the person to whom the option is granted is a 10%
     Stockholder, then the exercise price per share shall not be less than one
     hundred ten percent (110%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                                        3
<Page>

               2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                    (i)  in shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                    (ii) to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions (A) to a
     Corporation designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (B) to the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at
such time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option grant. However, no option shall have a term in excess of ten (10)
years measured from the option grant date.

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                    (i)   Should the Optionee cease to remain in Service for any
     reason other than death, Disability or Misconduct, then the Optionee shall
     have a period of three (3) months following the date of such cessation of
     Service during which to exercise each outstanding option held by such
     Optionee.

                    (ii)  Should Optionee's Service terminate by reason of
     Disability, then the Optionee shall have a period of twelve (12) months
     following the date of such cessation of Service during which to exercise
     each outstanding option held by such Optionee.

                                        4
<Page>

                    (iii) If the Optionee dies while holding an outstanding
     option, then the personal representative of his or her state or the person
     or persons to whom the option is transferred pursuant to the Optionee's
     will or the laws of inheritance shall have a twelve (12)-month period
     following the date of the Optionee's death to exercise such option.

                    (iv)  Under no circumstances, however, shall any such option
     be exercisable after the specified expiration of the option term.

                    (v)   During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding with respect to any and all option shares for which the
     option is not otherwise at the time exercisable or in which the Optionee is
     not otherwise at that time vested.

                    (vi)  Should Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to remain outstanding.

               2.  The Plan Administrator shall have the discretion, exercisable
either at the time an option is granted or at any time while the option remains
outstanding, to:

                    (i)  extend the period of time for which the option is to
     remain exercisable following Optionee's cessation of Service or death from
     the limited period otherwise in effect for that option to such greater
     period of time as the Plan Administrator shall deem appropriate, but in no
     event beyond the expiration of the option term, and/or

                    (ii) permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but also
     with respect to one or more additional installments in which the Optionee
     would have vested under the option had the Optionee continued in Service.

          D.   STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
recordholder of the purchased shares.

          E.   UNVESTED SHARES. The Plan Administrator shall have the discretion
to grant options which are exercisable for unvested shares of Common Stock.
Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such

                                        5
<Page>

repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right. The Plan Administrator may not impose a vesting schedule
upon any option grant or the shares of Common Stock subject to that option which
is more restrictive than twenty percent (20%) per year vesting, with the initial
vesting to occur not later than one (1) year after the option grant date.
However, such limitation shall not be applicable to any option grants made to
individuals who are officers of the Corporation, non-employee Board members or
independent consultants.

          F.   FIRST REFUSAL RIGHTS. Until such time as the Common Stock is
first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

          G.   LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Four shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options
shall not be subject to the terms of this Section II.

          A.   ELIGIBILITY. Incentive Options may only be granted to Employees.

          B.   EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

          C.   DOLLAR LIMITATION. The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one (1) calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

                                        6
<Page>

          D.   10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the option term shall not exceed five (5)
years measured from the option grant date.

     III. CORPORATE TRANSACTION

          A.   The shares subject to each option outstanding under the Plan at
the time of a Corporate Transaction shall automatically vest in full so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for all of the shares of Common Stock at
the time subject to that option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock. However, the shares subject to an
outstanding option shall not vest on such an accelerated basis if and to the
extent: (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and any repurchase rights of the
Corporation with respect to the unvested option shares are concurrently assigned
to such successor corporation (or parent thereof) or (ii) such option is to be
replaced with a cash incentive program of the successor corporation which
preserves the spread existing on the unvested option shares at the time of the
Corporate Transaction and provides for subsequent payout in accordance with the
same vesting schedule applicable to those unvested option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction, had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same.

          E.   The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to structure one or

                                        7
<Page>

more options so that those options shall automatically accelerate and vest in
full (and any repurchase rights of the Corporation with respect to the unvested
shares subject to those options shall immediately terminate) upon the occurrence
of a Corporate Transaction, whether or not those options are to be assumed in
the Corporate Transaction.

          F.   The Plan Administrator shall also have full power and authority,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to structure such option so that the shares subject
to that option will automatically vest on an accelerated basis should the
Optionee's Service terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which the option is assumed and the
repurchase rights applicable to those shares do not otherwise terminate. Any
option so accelerated shall remain exercisable for the fully-vested option
shares until the expiration or sooner termination of the option term. In
addition, the Plan Administrator may provide that one or more of the
Corporation's outstanding repurchase rights with respect to shares held by the
Optionee at the time of such Involuntary Termination shall immediately terminate
on an accelerated basis, and the shares subject to those terminated rights shall
accordingly vest at that time.

          G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction shall remain exercisable as an Incentive Option
only to the extent the applicable One Hundred Thousand Dollar limitation is not
exceeded. To the extent such dollar limitation is exceeded, the accelerated
portion of such option shall be exercisable as a NonStatutory Option under the
Federal tax laws.

          H.   The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                             STOCK ISSUANCE PROGRAM

     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

          A.   PURCHASE PRICE.

               1.   The purchase price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the issue date. However, the purchase
price per share of Common Stock issued to a 10% Stockholder shall not be less
than one hundred and ten percent (110%) of such Fair Market Value.

               2.   Subject to the provisions of Section I of Article Four,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                    (i)  cash or check made payable to the Corporation, or

                    (ii) past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   VESTING PROVISIONS.

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one (1) year after the issuance date. Such limitation shall
not apply to any Common Stock issuances made to the officers of the Corporation,
non-employee Board members or independent consultants.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the

                                        9
<Page>

Participant's unvested shares of Common Stock and (ii) such escrow arrangements
as the Plan Administrator shall deem appropriate.

               3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested. Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to such surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to those shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

          C.   FIRST REFUSAL RIGHTS. Until such time as the Common Stock is
first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

     II.  CORPORATE TRANSACTION

          A.   Upon the occurrence of a Corporate Transaction, all outstanding
repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

                                       10
<Page>

          B.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase rights with respect to those shares remain
outstanding, to provide that those rights shall automatically terminate on an
accelerated basis, and the shares of Common Stock subject to those terminated
rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase rights are assigned
to the successor corporation (or parent thereof).

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on

                                  ARTICLE FOUR

                                  MISCELLANEOUS

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Option Grant Program or the purchase price
for shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments and secured by the purchased shares. The terms of any such
promissory note (including the interest rate and the terms of repayment) shall
be established by the Plan Administrator in its sole discretion. In no event may
the maximum credit available to the Optionee or Participant exceed the sum of
(i) the aggregate option exercise price or purchase price payable for the
purchased shares (less the par value of those shares) plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

     II.  EFFECTIVE DATE AND TERM OF PLAN

          A.   The Plan shall become effective when adopted by the Board, but no
option granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders. If
such stockholder approval is not obtained within twelve (12) months after the
date of the Board's adoption of the Plan, then all options previously granted
under the Plan shall terminate and cease to be outstanding, and no further
options shall be granted and no shares shall be issued under the Plan. Subject
to such limitation, the Plan

                                       11
<Page>

Administrator may grant options and issue shares under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan.

          B.   The Plan shall terminate upon the earliest of (i) the expiration
of the ten (10)-year period measured from the date the Plan is adopted by the
Board, (ii) the date on which all shares available for issuance under the Plan
shall have been issued as vested shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. All options and
unvested stock issuances outstanding at the time of a clause (i) termination
event shall continue to have full force and effect in accordance with the
provisions of the documents evidencing those options or issuances.

     III. AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects. However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to options or unvested stock issuances at the time outstanding under the Plan
unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws and regulations.

          B.   Options may be granted under the Option Grant Program and shares
may be issued under the Stock Issuance Program which are in each instance in
excess of the number of shares of Common Stock then available for issuance under
the Plan, provided any excess shares actually issued under those programs shall
be held in escrow until there is obtained stockholder approval of an amendment
sufficiently increasing the number of shares of Common Stock available for
issuance under the Plan. If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess grants or issuances are
made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

     IV.  USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     V.   WITHHOLDING

          The Corporation's obligation to deliver shares of Common Stock upon
the exercise of any options granted under the Plan or upon the issuance or
vesting of any shares issued under the Plan shall be subject to the satisfaction
of all applicable Federal, state and local income and employment tax withholding
requirements.

                                       12
<Page>

     VI.  REGULATORY APPROVALS

          The implementation of the Plan, the granting of any options under the
Plan and the issuance of any shares of Common Stock (i) upon the exercise of any
option or (ii) under the Stock Issuance Program shall be subject to the
Corporation's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the options granted under it and
the shares of Common Stock issued pursuant to it.

     VII. NO EMPLOYMENT OR SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

     VIII.FINANCIAL REPORTS

          The Corporation shall deliver a balance sheet and an income statement
at least annually to each individual holding an outstanding option under the
Plan, unless such individual is a key Employee whose duties in connection with
the Corporation (or any Parent or Subsidiary) assure such individual access to
equivalent information.

   SECTION 2.1 LEASED PREMISES. Landlord leases to Tenant and Tenant leases from
Landlord the premises shown in Exhibit A (the "Premises"), containing
approximately the floor area set forth in Item 8 of the Basic Lease Provisions
and known by the suite number identified in Item 1 of the Basic Lease
Provisions. The Premises are located in the building identified in Item 1 of the
Basic Lease Provisions (which together with the underlying real property, is
called the "Building"), and is a portion of the project shown in Exhibit Y (the
"Project"). Tenant understands that the floor area set forth in Item 8 of the
Basic Lease Provisions may include, at Landlord's option, a factor approximating
the total square footage of any common lobby or internal common features of the
Building times the ratio of the actual square footage of the Premises to the
total square footage of the Building. If, upon completion of the space plans for
the Premises, Landlord's architect or space planner determines that the rentable
square footage of the Premises differs from that set forth in the Basic Lease
Provisions, then Landlord shall so notify Tenant and the Basic Rent (as shown in
Item 6 of the Basic Lease Provisions) shall be promptly adjusted in proportion
to the change in square footage. Within five (5) days following Landlord's
request, the parties shall memorialize the adjustments by executing an amendment
to this Lease prepared by Landlord, provided that the failure or refusal by
either party to execute the amendment shall not affect its validity.

   SECTION 2.2 ACCEPTANCE OF PREMISES. Tenant acknowledges that neither Landlord
nor any representative of Landlord has made any representation or warranty with
respect to the Premises or the Building or the suitability or fitness of either
for any purpose, including without limitation any representations or warranties
regarding zoning or other land use matters, and that neither Landlord nor any
representative of Landlord has made any representations or warranties regarding
(i) what other tenants or uses may be permitted or intended in the Building and
the Project, or (ii) any exclusivity of use by Tenant with respect to

                                        2
<Page>

its permitted use of the Premises as set forth in Item 3 of the Basic Lease
Provisions. Tenant further acknowledges that neither Landlord nor any
representative of Landlord has agreed to undertake any alterations or additions
or construct any improvements to the Premises except as expressly provided in
this Lease. The taking of possession or use of the Premises by Tenant for any
purpose other than construction shall conclusively establish that the Premises
and the Building were in satisfactory condition and in conformity with the
provisions of this Lease in all respects, except for those matters which Tenant
shall have brought to Landlord's attention on a written punch list The list
shall be limited to any items required to be accomplished by Landlord under the
Work Letter attached as Exhibit X and shall be delivered to Landlord within
thirty (30) days after the term (`Term") of this Lease commences as provided in
Article III below. If no items are required of Landlord under the Work Letter,
by taking possession of the Premises Tenant accepts the improvements in their
existing condition, and waives any right or claim against Landlord arising out
of the condition of the Premises. Nothing contained in this Section shall affect
the commencement of the Term or the obligation of Tenant to pay rent. Landlord
shall diligently complete all punch list items of which it is notified as
provided above.

   SECTION 2.3 BUILDING NAME AND ADDRESS. Tenant shall not utilize any name
selected by Landlord from time to time for the Building and/or the Project as
any part of Tenant's corporate or trade name. Landlord shall have the right to
change the name, address, number or designation of the Building or Project
without liability to Tenant.

                               ARTICLE III. TERM

   SECTION 3.1 GENERAL. The Term shall be for the period shown in Item 5 of the
Basic Lease Provisions. Subject to the provisions of Section 3.2 below, the Term
shall commence ("Commencement Date") on the earlier of (a) the date upon which
Landlord tenders possession of the Premises to Tenant with the Tenant
Improvements (as defined in the Work Letter Attached hereto) substantially
completed, or (b) the date Tenant acquires possession or commences use of the
Premises for any purpose other than construction of Tenant Improvements by
Tenant under the Work Letter. Within ten (10) days after possession of the
Premises is tendered to Tenant, the parties shall memorialize on a form provided
by Landlord die actual Commencement Date and the expiration date ("Expiration
Date") of this Lease. Tenant's failure to execute that form shall not affect the
validity of Landlord's determination of those dates.

   SECTION 3.2 DELAY IN POSSESSION. If Landlord, for any reason whatsoever,
cannot deliver possession of the Premises to Tenant on or before the Estimated
Commencement Date, this Lease shall not be void or voidable nor shall Landlord
be liable to Tenant for any resulting loss or damage. However, Tenant shall not
be liable for any rent and the Commencement Date shall not occur until Landlord
delivers possession of the Premises and the Premises are in fact available for
Tenant's occupancy with any Tenant Improvements that have been approved as per
Section 3.1 (a) above, except that if Landlord's failure to so deliver
possession on the Estimated Commencement Date is attributable to any action or
inaction by Tenant (including without limitation any Tenant Delay described in
the Work Letter attached to this Lease), then the Commencement Date shall not be
advanced to the date on which possession of the Premises is tendered to Tenant,
and Landlord shall be entitled to full performance by Tenant (including the
payment of rent) from the date Landlord would have been able to deliver the
Premises to Tenant but for Tenants delay(s).

                    ARTICLE IV. RENT AND OPERATING EXPENSES

   SECTION 4.1 BASIC RENT. From and after the Commencement Date, Tenant shall
pay to Landlord without deduction or offset, Basic Rent for the Premises in the
total amount shown (including subsequent adjustments, if any) in Item 6 of the
Basic Lease Provisions. Any rental adjustment shown in Item 6 shall be deemed to
occur on the specified monthly anniversary of the Commencement Date, whether or
not that date occurs at the end of a calendar month. The rent shall be due and
payable in advance commencing on the Commencement Date (as prorated for any
partial month) and continuing thereafter on the first day of each successive
calendar month of the Term. No demand, notice or invoice shall be required for
the payment of Basic Rent. An installment of rent in the amount of one (1) full
month's Basic Rent at the initial rate specified in Item 6 of the Basic Lease
Provisions shall be delivered to landlord concurrently with Tenant's execution
of this Lease and shall be applied against the Basic Rent fast due hereunder.

   SECTION 4.2 OPERATING EXPENSES.

      (a)  Tenant shall pay to Landlord, as additional rent, Tenant's Share of
"Operating Expenses", as defined below, incurred by Landlord in the operation of
the Building and Project. The term "Tenant's Share" means that portion of an
Operating Expense determined by multiplying the cost of such item by a faction,
the numerator of which is the floor area of the Premises and the denominator of
which is the total square footage of the floor area, as of the date on which the
computation is made, to be charged with such Operating Expense.

      (b)  Commencing prior to the start of the first full "Expense Recovery
Period" (as defined below) of the Lease, and prior to the start of each full or
partial Expense Recovery Period thereafter, Landlord shall give Tenant a written
estimate of the amount of Tenant's Share of operating Expenses for the Expense
Recovery Period. Tenant shall pay the estimated amounts to Landlord in equal
monthly installments, in advance, with Basic Rent. If Landlord has not furnished
its written estimate for any Expense Recovery Period by the time set forth
above, Tenant shall continue to pay cost reimbursements at the rates established
for the prior Expense Recovery Period, if any; provided that when the new
estimate is delivered to Tenant, Tenant shall, at the next monthly payment date,
pay any accrued cost reimbursements based upon the new estimate. For purposes
hereof, "Expense Recovery Period" shall mean every twelve mouth period during
the Term (or portion thereof for the first and last lease years) commencing July
1 and ending June 30.

      (c)  Within one hundred twenty (120) days after the end of each Expense
Recovery Period, Landlord shall furnish to Tenant a statement showing in
reasonable detail the actual or prorated Operating Expenses incurred by Landlord
during the period, and the parties shall within thirty (30) days thereafter make
any payment or allowance necessary to adjust Tenant's estimated payments, if
any, to the actual Tenant's Share as shown by the annual statement. Any delay or
failure by Landlord in delivering any statement hereunder shall not constitute a
waiver of Landlord's right to require Tenant to pay Tenant's Share of operating
Expenses pursuant hereto. Any amount due Tenant shall be credited against
installments next coming due under this Section 4.2, and any deficiency shall be
paid by Tenant together with the next installment. If Tenant has not made
estimated payments during the Expense Recovery Period, any amount owing by
Tenant pursuant to subsection (a) above shall be paid to Landlord in accordance
with

                                        4
<Page>

Article XVI. Should Tenant fail to object in writing to Landlord's determination
of actual Operating Expenses within sixty (60) days following delivery of
Landlord's expense statement, Landlord's determination of actual Operating
Expenses for the applicable Expense Recovery Period shall be conclusive and
binding on the parties and any future claims to the contrary shall be barred.

      (d)  Even though the Lease has terminated and the Tenant has vacated the
Premises, when the final determination is made of Tenant's Share of Operating
Expenses for the Expense Recovery Period in which the Lease terminates, Tenant
shall upon notice pay the entire increase due over the estimated expenses paid.
Conversely, any overpayment made in the event expenses decrease shall be rebated
by Landlord to Tenant.

      (e)  If, at any time during any Expense Recovery Period, any one or more
of the Operating Expenses are increased to a rate(s) of amount(s) in excess of
the rate(s) or amount(s) used in calculating the estimated expenses for the
year, then the estimate of Tenant's Share of Operating Expenses shall be
increased for the month in which such rate(s) or amount(s) becomes effective and
for all succeeding months by an amount equal to Tenant's Share of the increase.
Landlord shall give Tenant written notice of the amount or estimated amount of
the increase, the month in which the increase will become effective, Tenants
Share thereof and the month for which the payments are due. Tenant shall pay the
increase to Landlord as a part of Tenants monthly payments of estimated expenses
as provided in paragraph (b) above, commencing with the month in which
effective.

      (f)  The term "Operating Expenses" shall mean and include all "Project
Costs" (as hereafter defined) and "Property `taxes" (as hereafter defined).

      (g)  The term "Project Costs" shall include all expenses of operation and
maintenance of the Building and the Project, together with all appurtenant
Common Areas (as defined in Section 6.2), and shall include the following
charges byway of illustration but not limitation: water and sewer charges;
insurance premiums or reasonable premium equivalents should Landlord elect to
self-insure any risk that Landlord is authorized to insure hereunder; license,

compliance of any laws or changes in laws applicable to the Building or the
Project; the cost of any capital investments (other than tenant improvements for
specific tenants) to the extent of the amortized amount thereof over the useful
life of such capital investments calculated at a market cost of funds, all as
determined by Landlord, for each such year of useful life during the Tern; costs
associated with the procurement and maintenance of an air conditioning, heating
and ventilation service agreement, and procurement and maintenance of an
intrabuilding network cable service agreement for any intrabuilding network
cable telecommunications lines within the Project, and any other installation,

reasonably allocated wages and salaries, fringe benefits, and payroll taxes for
administrative and other personnel directly applicable to the Building and/or
Project, including both Landlord's personnel and outside personnel; any expense

<Page>

6.2, 6.4, 72, and 10.2; and a reasonable overhead/management fee for the
professional operation of the Project Notwithstanding anything to the contrary
herein, Tenant's Share of any such property management fees shall be determined
by multiplying the actual property management fee charged (which from time to
time may be with respect to the Building only, a portion of the Project only,
the entire Project, or the Project together with other properties owned by
Landlord and/or its affiliates) by a fraction, the numerator of which is the
floor area of the Premises (as set forth in Item 8 of the Basic Lease Provisions
contained in the Lease), and the denominator of which is the total square
footage of space charged with such management fee actually leased to tenants
(including Tenant). It is understood that Project Costs shall include
competitive charges for direct services provided by any subsidiary or division
of Landlord.

      (h)  The term "Property Taxes" as used herein shall include the following:
(i) all real estate taxes or personal property taxes, as such property taxes may
be reassessed from time to time; and (ii) other taxes, charges and assessments
which are levied with respect to this Lease or to the Building and/or the
Project, and any improvements, fixtures and equipment and other property of
Landlord located in the Building and/or the Project, except that general net
income and franchise taxes imposed against Landlord shall be excluded; and (iii)
all assessments and fees for public improvements, services, and facilities and
impacts thereon, including without limitation arising out of any Community
Facilities Districts, "Mello Roos" districts, similar assessment districts, and
any traffic impact mitigation assessments or fees; (iv) any tax, surcharge or
assessment which shall be levied in addition to or in lieu of real estate or
personal property taxes, other than taxes covered by Article VIII; and (v) costs
and expenses incurred in contesting the amount or validity of any Property Tax
by appropriate proceedings.

   SECTION 4.3 SECURITY DEPOSIT. Concurrently with Tenant's delivery of this
Lease, Tenant shall deposit with Landlord the sum, if any, stated in Item 9 of
the Basic Lease Provisions, to be held by Landlord as security for the full and
faithful performance of Tenant's obligations under this Lease (the "Security
Deposit"). Subject to the last sentence of this Section, the Security Deposit
shall be understood and agreed to be the property of Landlord upon Landlord's
receipt thereof, and may be utilized by landlord in its discretion towards the
payment of all prepaid expenses by Landlord for which Tenant would be required
to reimburse Landlord under this Lease, including without limitation brokerage
commissions and Tenant Improvement costs. Upon any default by Tenant, including
specifically Tenant's failure to pay rent or to abide by its obligations under
Sections 7.1 and 15.3 below, whether or not Landlord is informed of or has
knowledge of the default, the Security Deposit shall be deemed to be
automatically and immediately applied, without waiver of any rights Landlord may
have under this Lease or at law or in equity as a result of the default, as a
setoff for frill or partial compensation for that default If any portion of the
Security Deposit is applied after a default by Tenant, Tenant shall within five
(5) days after written demand by Landlord deposit cash with Landlord in an
amount sufficient to restore the Security Deposit to its original amount.
Landlord shall not be required to keep this Security Deposit separate from its
general funds, and Tenant shall not be entitled to interest on the Security
Deposit. If Tenant fully performs its obligations under this Lease, the Security
Deposit shall be retained to Tenant (or, at Landlord's option, to the last
assignee of Tenant's interest in this lease) after the expiration of the Term,
provided that Landlord may retain the Security Deposit to the extent and until
such time as all amounts due from Tenant in accordance with this Lease have been
determined and paid in full.

Landlord and shall entitle Landlord to injunctive relief in addition to any
other available remedy. Tenant, at its expense, shall procure, maintain and make
available for Landlord's inspection throughout the Term, all governmental

      (b)  Tenant shall not cause or permit any Hazardous Materials to be
brought upon, stored, used, generated, released or disposed of on, under, from
or about the Premises (including without limitation the soil and groundwater
thereunder) without the prior written consent of Landlord. Notwithstanding the
foregoing, Tenant shall have the right, without obtaining prior written consent
of Landlord, to utilize within the Premises standard office products that may
contain Hazardous Materials (such as photocopy toner, "White Out", and the

original retail packaging, shall follow all instructions on such packaging with
respect to the storage, use and disposal of such products, and shall otherwise
comply with all applicable laws with respect to such products, and (ii) all of
the other terms and provisions of this Section 5.3 shall apply with respect to
Tenant's storage, use and disposal of all such products. Landlord may, in its
sole discretion, place such conditions as Landlord deems appropriate with
respect to any such Hazardous Materials, and may further require that Tenant
demonstrate that any such Hazardous Materials are necessary or useful to
Tenant's business and will be generated, stored, used and disposed of in a
manner that complies with all applicable laws and regulations pertaining thereto
and with good business practices. Tenant understands that Landlord may utilize
an environmental consultant to assist in determining conditions of approval in
connection with the storage, generation, release, disposal or use of Hazardous
Materials by Tenant on or about the Premises, and/or to conduct periodic
inspections of the storage, generation, use, release and/or disposal of such
Hazardous Materials by Tenant on and from the Premises, and Tenant agrees that

Premises for the

                                        8
<Page>

twelve-month period prior thereto, and which Tenant desires to store, generate,
use, release and/or dispose of on, under or about the Premises for the

to utilize Hazardous Materials upon the Premises, Tenant shall promptly provide
Landlord with complete and legible copies of all the following environmental
documents relating thereto: reports filed pursuant to any self-reporting
requirements; permit applications, permits, monitoring reports, workplace

reports, notices, listings and correspondence (even those which may be
considered confidential) of or concerning the release, investigation of,
compliance, cleanup, remedial and corrective actions, and abatement of Hazardous
Materials; and all complaints, pleadings and other legal documents filed by or
against Tenant related to Tenant's use, handling, storage, release and/or
disposal of Hazardous Materials.

      (d)  Landlord and its agents shall have the right, but not the obligation,
to inspect, sample and/or monitor the Premises and/or the soil or groundwater
thereunder at any time to determine whether Tenant is complying with the terns
of this Section 5.3, and in connection therewith Tenant shall provide Landlord
with full access to all relevant facilities, records and personnel. If Tenant is
not in compliance with any of the provisions of this Section 5.3, or in the
event of a release of any Hazardous Material on, under or about the Premises
caused or permitted by Tenant, its agents, employees, contractors, licensees or
invitees, Landlord and its agents shall have the right, but not the obligation,
without limitation upon any of Landlord's other rights and remedies under this
Lease, to immediately enter upon the Premises without notice and to discharge
Tenant's obligations under this Section 5.3 at Tenant's expense, including
without limitation the taking of emergency or long-term remedial action.
Landlord and its agents shall endeavor to minimize interference with Tenant's
business in connection therewith, but shall not be liable for any such
interference. In addition, Landlord, at Tenant's expense, shall have the right,
but not the obligation, to join and participate in any legal proceedings or
actions initiated in connection with any claims arising out of the storage,
generation, use, release and/or disposal by Tenant or its agents, employees,
contractors, licensees or invitees of Hazardous Materials on, under, from or
about the Premises.

      (e)  If the presence of any Hazardous Materials on, under, from or about
the Premises or the Project caused or permitted by Tenant or its agents,
employees, contractors, licensees or invitees results is (i) injury to any
person, (ii) injury to or any contamination of the Premises or the Project, or
(iii) injury to or contamination of any real or personal property wherever
situated, Tenant, at its expense, shall promptly take all actions necessary to
return the Premises and the Project and any other affected real or personal
property owned by Landlord to the condition existing prior to the introduction
of such Hazardous Materials and to remedy or repair any such injury or
contamination, including without limitation, any cleanup, remediation, removal,
disposal, neutralization or other treatment of any such Hazardous Materials.
Notwithstanding the foregoing, Tenant shall not, without Landlord's prior
written consent, take any remedial action in response to the presence of any
Hazardous Materials on, under or about the Premises or the Project or any other
affected real or personal property owned by Landlord or enter into any similar
agreement, consent, decree or other compromise with any governmental agency with
respect to any Hazardous Materials claims; provided however, Landlord's prior
written consent

                                        9
<Page>

shall not be necessary in the event that the presence of Hazardous Materials on,
under or about the Premises or the Project or any other affected real or
personal property owned by Landlord (i) imposes an immediate threat to the
health, safety of welfare of any individual or (ii) is of such a nature that an
immediate remedial response is necessary and it is not possible to obtain
Landlord's consent before taking such action. To the fullest extent permitted by
law, Tenant shall indemnify, hold harmless, protect and defend (with attorneys
acceptable to Landlord) Landlord and any successors to all or any portion of
Landlord's interest in the Premises and the Project and any other real or
personal property owned by Landlord from and against any and all liabilities,
losses, damages, diminution in value, judgments, flues, demands, claims,
recoveries, deficiencies, costs and expenses (including without limitation
attorneys' fees, court costs and other professional expenses), whether
foreseeable or unforeseeable, arising directly or indirectly out of the use,
generation, storage, treatment, release, on- or off-site disposal or
transportation of Hazardous Materials on, into, from, tinder or about the
Premises, the Building and the Project and any other real or personal property
owned by Landlord caused or permitted by Tenant, its agents, employees,
contractors, licensees or invitees, specifically including without limitation
the cost of any required or necessary repair, restoration, cleanup or
detoxification of the Premises, the Building and the Project and any other real
or personal property owned by Landlord, and the preparation of any closure or
other required plans, whether or not such action is required or necessary during
the Term or after the expiration of this Lease. If Landlord at any time
discovers that Tenant or its agents, employees, contractors, licensees or
invitees may have caused or permitted the release of a Hazardous Material on,
under, from or about the Premises or the Project or any other real or personal
property owned by Landlord, Tenant shall, at Landlord's request, immediately
prepare and submit to Landlord a comprehensive plan, subject to Landlord's
approval, specifying the actions to be taken by Tenant to return the Premises or
the Project or any other real or personal property owned by Landlord to the
condition existing prior to the introduction of such Hazardous Materials. Upon
Landlord's approval of such cleanup plan, Tenant shall, at its expense, and
without limitation of any rights and remedies of Landlord under this Lease or at
law or in equity, immediately implement such plan and proceed to cleanup such
Hazardous Materials in accordance with all applicable laws and as required by
such plan and this Lease. The provisions of this subsection (e) shall expressly
survive the expiration or sooner termination of this Lease.

      (f)  Landlord hereby discloses to Tenant, and Tenant hereby acknowledges,
certain facts relating to Hazardous Materials at the Project known by Landlord
to exist as of the date of this Lease, as more particularly described in it
EXHIBIT C attached hereto. Tenant shall have no liability or responsibility with
respect to the Hazardous Materials facts described in EXHIBIT C, nor with
respect to any Hazardous Materials which Tenant proves were not caused or
permitted by Tenant, its agents, employees, contractors, licensees or invitees.
Notwithstanding the preceding two sentences, Tenant agrees to notify its agents,
employees, contractors, licensees, and invitees of any exposure or potential
exposure to Hazardous Materials at the Premises that Landlord brings to Tenant's
attention.

                       ARTICLE VI. COMMON AREAS; SERVICES

   SECTION 6.1 UTILITIES AND SERVICES. Tenant shall be responsible for and shall
pay promptly, directly to the appropriate supplier, all charges for water, gas,
electricity, sewer, beat, light, power, telephone, refuse pickup, janitorial
service, interior landscape maintenance

                                       10
<Page>

and all other utilities, materials and services furnished directly to Tenant or
the Premises or used by Tenant in, on or about the Premises during the Term,
together with any taxes thereon. If any utilities or services are not separately
metered or assessed to Tenant, Landlord shall make a reasonable determination of
Tenant's proportionate share of the cost of such utilities and services and
Tenant shall pay such amount to Landlord, as an item of additional rent, within
ten (10) days after receipt of landlord's statement or invoice therefor.
Alternatively, Landlord may elect to include such cost in the definition of
Building Costs in which event Tenant shall pay Tenant's proportionate share of
such costs in the manner set forth in Section 4.2. Landlord shall not be liable
for damages or otherwise for any failure or interruption of any utility or other
service furnished to the Premises, and no such failure or interruption shall be
deemed an eviction or entitle Tenant to terminate this Lease or withhold or
abate any rent due hereunder. Landlord shall at all reasonable times have free
access to all electrical and mechanical installations of Landlord.

   SECTION 6.2 OPERATION AND MAINTENANCE OF COMMON AREAS. During the Term,
Landlord shall operate all Common Areas within the Building and the Project. The
term "Common Areas" shall mean all areas within the exterior boundaries of the
Building and other buildings in the Project which are not held for exclusive use
by persons entitled to occupy space, and all other appurtenant areas and
improvements provided by Landlord for the common use of Landlord and tenants and
their respective employees and invitees, including without limitation parking
areas and structures, driveways, sidewalks, landscaped and planted areas,
hallways and interior stairwells not located within the premises of any tenant,
common electrical rooms and roof access entries, common entrances and lobbies,
elevators, and restrooms not located within the premises of any tenant.

   SECTION 6.3 USE OF COMMON AREAS. The occupancy by Tenant of the Premises
shall include the use of the Common Areas in common with Landlord and with all
others for whose convenience and use the Common Areas may be provided by
Landlord, subject, however, to compliance with all rules and regulations as are
prescribed from time to time by Landlord. Landlord shall operate and maintain
the Common Areas in the manner Landlord may determine to be appropriate. All
costs incurred by Landlord for the maintenance and operation of the Common Areas
shall be included in Project Costs unless any particular cost incurred can be
charged to a specific tenant of the Project. Landlord shall at all times during
the Term have exclusive control of the Common Areas, and may restrain any use or
occupancy, except as authorized by Landlord's rules and regulations. Tenant
shall keep the Common Areas clear of any obstruction or unauthorized use related
to Tenant's operations. Nothing in this Lease shall be deemed to impose
liability upon Landlord for any damage to or loss of the property of, or for any
injury to, Tenant, its invitees or employees. Landlord may temporarily close any
portion of the Common Areas for repairs, remodeling and/or alterations, to
prevent a public dedication or the accrual of prescriptive rights, or for any
other reason deemed sufficient by Landlord, without liability to Landlord,
provided, however, Landlord shall promptly use reasonable efforts to minimize
any unreasonable interference of Tenant's use of and access to the Premises.

   SECTION 6.4 PARKING. Tenant shall be entitled to the number of vehicle
parking spaces set forth in Item 14 of the Basic Lease Provisions, which spaces
shall be unreserved and unassigned, on those portions of the Common Areas
designated by Landlord for parking. Tenant shall not use more parking spaces
than such number. All parking spaces shall be used only for

                                       11
<Page>

parking by vehicles no larger than full size passenger automobiles or pickup
trucks. Tenant shall not permit or allow any vehicles that belong to or are
controlled by Tenant or Tenant's employees, suppliers, shippers, customers or

from within those motor vehicles, or for any injury to Tenant, its visitors or
employees, unless ultimately determined to be caused by the sole active
negligence or willful misconduct of Landlord. Landlord shall have the right to

upon written or oral notice (except in emergencies, when no notice shall be
required) have the right to enter the Premises to inspect them, to supply
services in accordance with this Lease, to protect the interests of Landlord in
the Premises, and to submit the Premises to prospective or actual purchasers or
encumbrance holders (or, during the last one hundred and eighty (180) days of
the Term or when an uncured Tenant default exists, to prospective tenants), all

of rent except as provided elsewhere in this Lease. Landlord shall have the
right, if desired, to retain a key which unlocks all of the doors in the
Premises, excluding Tenant's vaults and safes, and Landlord shall have the right
to use any and all means which Landlord may deem proper to open the doors in an

and reconnect Tenants personal property and equipment within the new space;
provided that Landlord may elect to cause such work to be done by its
contractors. Landlord shall also reimburse Tenant for such other reasonable
out-of-pocket costs that Tenant may incur in connection with the relocation,
including without limitation necessary stationery revisions, provided that a
reasonable estimate thereof is given to Landlord within twenty (20) days

of the parties to reach an agreement on the proposed relocation), or should
Tenant thereafter fail to comply with the terms thereof, then Landlord may at
its option elect to terminate this Lease upon not less than ninety (90) days
prior written notice to Tenant. In the event of such termination, Tenant's
obligation to pay Basic Rent during the final two (2) months of the Term shall
be waived. Upon the effective date of any termination of this Lease, Tenant
shall vacate the Premises in accordance with Section 15.3. Notwithstanding the
foregoing, however, Landlord agrees that it shall not enforce the provisions of
this Section 7.6 during the initial thirty-six (36) month Term.

quantity for comparable space within the Project ("Above Standard
Improvements"), and against any alterations, additions or like improvements made
to the Premises by or on behalf of Tenant. When possible Tenant shall cause its
personal property, Above Standard Improvements and alterations to be assessed
and billed separately

                                       15
<Page>

from the real property of which the Premises form a part. If any taxes on
Tenant's personal property, Above Standard Improvements and/or alterations are
levied against Landlord or Landlord's property and if Landlord pays the same, or
if the assessed value of Landlords property is increased by the inclusion of a
value placed upon the personal property, Above Standard Improvements and/or
alterations of Tenant and if Landlord pays the taxes based upon the increased
assessment, Tenant shall pay to Landlord the taxes so levied against Landlord or
the proportion of the taxes resulting from the increase in the assessment. In
calculating what portion of any tax bill which is assessed against Landlord
separately, or Landlord and Tenant jointly, is attributable to Tenant's Above
Standard Improvements, alterations and personal property, Landlords reasonable
determination shall be conclusive.

                      ARTICLE IX. ASSIGNMENT A" SUBLETTING

   SECTION 9.1 RIGHTS OF PARTIES.

      (a)  Notwithstanding any provision of this Lease to the contrary, Tenant
will not, either voluntarily or by operation of law, assign, sublet, encumber,
or otherwise transfer all or any part of Tenant's interest in this lease, or
permit the Premises to be occupied by anyone other than Tenant without Landlords
prior written consent, which consent shall not unreasonably be withheld in
accordance with the provisions of Section 9.1(b). No assignment (whether
voluntary, involuntary or by operation of low) and no subletting shall be valid
or effective without Landlord's prior written consent and, at Landlord's
election, any such assignment or subletting or attempted assignment or
subletting shall constitute a material default of this Lease. Landlord shall not
be deemed to have given its consent to any assignment or subletting by any other
course of action, including its acceptance of any name for listing in the
Building directory. To the extent not prohibited by provisions of the Bankruptcy
Code, 11 U.S.C. Section 101 et seq. (the "Bankruptcy Code"), including Section
365(f)(1), Tenant on behalf of itself and its creditors, administrators and
assigns waives the applicability of Section 365(e) of the Bankruptcy Code unless

this Lease is assigned to any person or entity pursuant to the provisions of the
Bankruptcy Code, any and all monies or other considerations to be delivered in
connection with the assignment shall be delivered to Landlord, shall be and
remain the exclusive property of Landlord and shall not constitute property of
Tenant or of the estate of Tenant within the meaning of the Bankruptcy Code. Any
person or entity to which this Lease is assigned pursuant to the provisions of
the Bankruptcy Code shall be deemed to have assumed all of the obligations
arising under this Lease on and after the date of the assignment, and shall upon
demand execute and deliver to Landlord an instrument confirming that assumption.

fast notify Landlord of its desire and shall submit in writing to Landlord: (i)
the name and address of the proposed transferee; (ii) the nature of any proposed

proposed assignee or subtenant complying with the requirements of EXHIBIT D
hereto; (v) a completed Environmental Questionnaire from the proposed assignee
or subtenant and (vi) any other information requested by Landlord and reasonably
related to the transfer. Except as provided in

consent, provided: (1) the use of the Premises will be consistent with the
provisions of this Lease and with Landlord's commitment to other tenants of the
Building and Project (2) the proposed assignee or subtenant has not been
required by any prior landlord, lender or governmental authority to take
remedial action in connection with Hazardous Materials contaminating a property
arising out of the proposed assignee's or subtenant's actions or use of the
property in question and is not subject to any enforcement order issued by any
governmental authority in connection with the use, disposal or storage of a
Hazardous Material; (3) at Landlord's election, insurance requirements shall be
brought into conformity with Landlord's then current leasing practice; (4) any
proposed subtenant or assignee demonstrates that it is financially responsible
by submission to Landlord of all reasonable information as Landlord may request
concerning the proposed subtenant or assignee, including, but not limited to, a
balance sheet of the proposed subtenant or assignee as of a date within ninety
(90) days of the request for Landlord's consent, statements of income or profit
and loss of the proposed subtenant or assignee for the two-year period preceding
the request for Landlord's consent, and/or a certification signed by the
proposed subtenant or assignee that it has not been evicted or been in arrears
in rent at any other leased premises for the 3-year period preceding the request
for Landlord's consent (5) any proposed subtenant or assignee demonstrates to
Landlord's reasonable satisfaction a record of successful experience in
business; (6) the proposed assignee or subtenant is not an existing tenant of
the Building or Project or a prospect with whom Landlord is negotiating to
become a tenant at the Building or Project and (7) the proposed transfer will
not impose additional burdens or adverse tax effects on Landlord. If Tenant has
any exterior sign rights under this Lease, such rights are personal to Tenant
and may not be assigned or transferred to any assignee of this Lease or
subtenant of the Premises without Landlord's prior written consent, which may be
withheld in Landlord's sole and absolute discretion.

      If Landlord consents to the proposed transfer, Tenant may within ninety
(90) days after the date of the consent effect the transfer upon the terms
described in the information furnished to Landlord; provided that any material
change in the terms shall be subject to Landlord's consent as set forth in this
Section. Landlord shall approve or disapprove any requested transfer within
twenty (20) days following receipt of Tenant's written request, the information
set forth above, and the fee set forth below.

      (c)  Notwithstanding the provisions of Subsection (b) above, in lieu of
consenting to a proposed assignment or subletting, Landlord may elect to (i)
sublease the Premises (or the portion proposed to be subleased), or take an
assignment of Tenant's interest in this Lease, upon the same terms as offered to
the proposed subtenant or assignee (excluding terms relating to the purchase of
personal property, the use of Tenant's name or the continuation of Tenant's
business), or (ii) terminate this Lease as to the portion of the Premises
proposed to be subleased or assigned with a proportionate abatement in the rent
payable under this Lease, effective on the date that the proposed sublease or
assignment would have become effective. Landlord may thereafter, at its option,
assign or re-let any space so recaptured to any third party, including without
limitation the proposed transferee of Tenant.

      (d)  Tenant' agrees that fifty percent (50%) of any amounts paid by the
assignee or subtenant, however described, in excess of (i) the Basic Rent
payable by Tenant hereunder, or in the case of a sublease of a portion of the
Premises, in excess of the Basic Rent reasonably

                                       17
<Page>

allocable to such portion, plus (ii) Tenant's direct out-of-pocket costs which
Tenant certifies to Landlord have been paid to provide occupancy related
services to such assignee or subtenant of a nature commonly provided by
landlords of similar space, shall be the property of Landlord and such amounts
shall be payable directly to Landlord by the assignee or subtenant or, at
Landlord's option, by Tenant At Landlord's request, a written agreement shall be
entered into by and among Tenant, Landlord and the proposed assignee or
subtenant confirming the requirements of this subsection.

      (e)  Tenant shall pay to Landlord a fee of Five Hundred Dollars ($500.00)
if and when any transfer hereunder is requested by Tenant. Such fee is hereby
acknowledged as a reasonable amount to reimburse Landlord for its costs of
review and evaluation of a proposed assignee/sublessee, and Landlord shall not
be obligated to commence such review and evaluation unless and until such fee is
paid.

   SECTION 9.2 EFFECT OF TRANSFER. No subletting or assignment, even with the
consent of Landlord, shall relieve Tenant of its obligation to pay rent and to
perform all its other obligations under this Lease. Moreover, Tenant shall
indemnify and hold Landlord harmless, as provided in Section 10.3, for any act
or omission by an assignee or subtenant. Each assignee, other than Landlord,
shall be deemed to assume all obligations of Tenant under this Lease and shall
be liable jointly and severally with Tenant for the payment of all rent, and for
the due performance of all of Tenant's obligations, under this Lease. No
transfer shall be binding on Landlord unless any document memorializing the
transfer is delivered to Landlord and both the assignee/subtenant and Tenant
deliver to Landlord an executed consent to transfer instrument prepared by
Landlord and consistent with the requirements of this Article. The acceptance by
Landlord of any payment due under this Lease from any other person shall not be
deemed to be a waiver by Landlord of any provision of this Lease or to be a
consent to any transfer. Consent by Landlord to one or more transfers shall not
operate as a waiver or estoppel to the future enforcement by Landlord of its
rights under this Lease.

   SECTION 9.3 SUBLEASE REQUIREMENTS. The following terms and conditions shall
apply to any subletting by Tenant of all or any part of the Premises and shall
be deemed included in each sublease:

      (a)  Each and every provision contained in this Lease (other than with
respect to the payment of rent hereunder) is incorporated by reference into and
made a part of such sublease, with "Landlord" hereunder meaning the sublandlord
therein and "Tenant" hereunder meaning the subtenant therein.

      (b)  Tenant hereby irrevocably assigns to Landlord all of Tenant's
interest in all rentals and income arising from any sublease of the Premises,
and Landlord may collect such rent and income and apply same toward Tenant's
obligations under this Lease; provided, however, that until a default occurs in
the performance of Tenant's obligations under this Lease, Tenant shall have the
right to receive and collect the sublease rentals. Landlord shall not, by reason
of this assignment or the collection of sublease rentals, be deemed liable to
the subtenant for the performance of any of Tenant's obligations under the
sublease. Tenant hereby irrevocably authorizes and directs any subtenant, upon
receipt of a written notice from Landlord stating that an uncured default exists
in the performance of Tenant's obligations under this

                                       18
<Page>

Lease, to pay to Landlord all stuns then and thereafter due under the sublease.
Tenant agrees that the subtenant may rely on that notice without any duty of
further inquiry and notwithstanding any notice or claim by Tenant to the
contrary. Tenant shall have no right or claim against the subtenant or Landlord
for any rentals so paid to Landlord.

      (c)  In the event of the termination of this Lease, Landlord may, at its
sole option, takeover Tenant's entire interest in any sublease and, upon notice
from Landlord, the subtenant shall attorn to Landlord. In no event, however,
shall Landlord be liable for any previous act or omission by Tenant under the
sublease or for the return of any advance rental payments or deposits under the
sublease that have not been actually delivered to Landlord, nor shall Landlord
be bound by any sublease modification executed without Landlord's consent or for
any advance rental payment by the subtenant in excess of one month's rent. The
general provisions of this Lease, including without limitation those pertaining
to insurance and indemnification, shall be deemed incorporated by reference into
the sublease despite the termination of this Lease.

Tenant's assets (other than bulk sales in the ordinary course of business) or,
if Tenant is a corporation, an unincorporated association, or a partnership, the
transfer, assignment or hypothecation of any stock or interest in such
corporation, association, or partnership in the aggregate of twenty-five percent
(25%) (except for publicly traded shares of stock constituting a transfer of
twenty-five percent (25%) or more in the aggregate, so long as no change in the
controlling interest of Tenant occurs as a result thereof) shall be deemed an
assignment within the meaning and provisions of this Article. Notwithstanding
the foregoing, Landlord's consent shall not be required for the assignment of
this Lease as a result of a merger by Tenant with or into another entity, so
long as (i) the net worth of the successor entity after such merger is at least
equal to the greater of the net worth of Tenant as of the execution of this
Lease by Landlord or the net worth of Tenant immediately prior to the date of
such merger, evidence of which, satisfactory to Landlord, shall be presented to
Landlord prior to such merger, (u) Tenant shall provide to Landlord, prior to
such merger, written notice of such merger and such assignment documentation and
other information as Landlord may request in connection therewith, and (iii) all
of the other terms and requirements of this Article shall apply with respect to
such assignment.

property of Landlord, whether or not Landlord is obligated to or elects to make
any repairs. At Landlord's option, Landlord may self-insure all or any portion
of the risks for which Landlord elects to provide insurance hereunder.

   SECTION 10.3 TENANT'S INDEMNITY. To the fullest extent permitted by law,
Tenant shall defend, indemnify, protect, save and hold harmless Landlord, its
agents, and any and all affiliates of Landlord, including, without limitation,

control with Landlord, from and against any and all claims, liabilities, costs
or expenses arising either before or after the Commencement Date from Tenant's
use or occupancy of the Premises, the Building or the Common Areas, or from the
conduct of its business, or from any activity, work, or thing done, permitted or
suffered by Tenant or its agents, employees, invitees or licensees in or about
the Premises, the Building or the Common Areas, or from any default in the
performance of any obligation on Tenant's part to be performed under this Lease,
or from any act or negligence of Tenant or its agents, employees, visitors,
patrons, guests, invitees or licensees. Landlord may, at its option, require
Tenant to assume Landlord's defense in any action covered by this Section

expressly survive the expiration or sooner termination of this Lease.

   SECTION 10.4 LANDLORD'S NONLIABILITY. Landlord shall not be liable to Tenant,
its employees, agents and invitees, and Tenant hereby waives all claims against
Landlord for loss of or damage to any property, or loss or interruption of
business of income, or any other loss, cost, damage, injury or liability
whatsoever (including without limitation any consequential damages and lost
profit or opportunity costs) resulting from, but not limited to, Acts of God,
acts of civil disobedience or insurrection, acts or omissions of other tenants
within the Project or their agents, employees, contractors, guests or invitees,
fire, explosion, falling plaster, steam, gas, electricity, water or rain which
may leak or flow from or into any part of the Premises or from the breakage,
leakage, obstruction or other defects of the pipes, sprinklers, wires,
appliances, plumbing, air conditioning, electrical works or other fixtures in
the Building, whether the damage or injury results from conditions arising in
the Premises or in other portions of the Building. It is understood that any
such condition may require the temporary evacuation or closure of all or a

there shall be no abatement of rent and no liability of Landlord by reason of
any injury to or interference with Tenant's business (including without
limitation consequential damages and lost profit or opportunity costs) arising

little as reasonably practicable with the conduct of Tenant's business in the
Premises. Neither Landlord nor its agents shall be liable for interference with
light or other similar intangible interests. Tenant shall immediately notify
Landlord in case of fire or accident in the Premises, the Building or the
Project and of defects in any improvements or equipment.

   SECTION 10.5 WAIVER OF SUBROGATION. Landlord and Tenant each hereby waives
all rights of recovery against the other and the other's agents on account of
loss and damage occasioned to the property of such waiving party to the extent
only that such loss or

                                       20
<Page>

damage is required to be insured against under any "all risk" property insurance
policies required by this Article X; provided however, that (i) the foregoing
waiver shall not apply to the extent of Tenant's obligations to pay deductibles
under any such policies and this Lease, and (ii) if any loss is due to the act,
omission or negligence or willful misconduct of Tenant or its agents, employees,
contractors, guests or invitees, Tenant's liability insurance shall be primary
and shall cover all losses and damages prior to any other insurance hereunder.
By this waiver it is the intent of the parties that neither Landlord nor Tenant
shall be liable to any insurance company (by way of subrogation or otherwise)
insuring the other party for any loss or damage insured against under any
"all-risk" property insurance policies required by this Article, even though
such loss or damage might be occasioned by the negligence of such party, its
agents, employees, contractors, guests or invitees. The provisions of this
Section shall not limit the indemnification provisions elsewhere contained in
this Lease.

                       ARTICLE XI. DAMAGE OR DESTRUCTION

   SECTION 11.1 RESTORATION.

      (a)  If the Building of which the Premises are apart is damaged, Landlord
shall repair that damage as soon as reasonably possible, at its expense, unless:
(i) Landlord reasonably determines that the cost of repair is not covered by
Landlord's fire and extended coverage insurance plus such additional amounts
Tenant elects, at its option, to contribute, excluding however the deductible
(for which Tenant shall be responsible for Tenant's Share); (ii) Landlord
reasonably determines that the Premises cannot, with reasonable diligence, be
fully repaired by Landlord (or cannot be safely repaired because of the presence
of hazardous factors, including without limitation Hazardous Materials,
earthquake faults, and other similar dangers) within two hundred seventy (270)
days after the date of the damage; (iii) an event of default by Tenant has
occurred and is continuing at the time of such damage; or (iv) the damage occurs
during the final twelve (12) months of the Term. Should Landlord elect not to
repair the damage for one of the preceding reasons, Landlord shall so notify
Tenant in writing within sixty (60) days after the damage occurs and this Lease
shall terminate as of the date of that notice.

      (b)  Unless Landlord elects to terminate this Lease in accordance with
subsection (a) above, this Lease shall continue in effect for the remainder of
the Term; provided that so long as Tenant is not in default trader this Lease,
if the damage is so extensive that Landlord reasonably determines that the
Premises cannot, with reasonable diligence, be repaired by Landlord (or cannot
be safely repaired because of the presence of hazardous factors, earthquake
faults, and other similar dangers) so as to allow Tenant's substantial use and
enjoyment of the Premises within two hundred seventy (270) days after the date
of damage, then Tenant may elect to terminate this Lease by written notice to
Landlord within the sixty (60) day period stated in subsection (a).

      (c)  Commencing on the date of any damage to the Building, and ending on
the sooner of the date the damage is repaired or the date this Lease is
terminated, the rental to be paid under this Lease shall be abated in the same
proportion that the floor area of the Premises that is rendered unusable by the
damage from time to time bears to the total floor area of the Premises, but only
to the extent that any business interruption insurance proceeds are received by
Landlord therefor from Tenant's insurance described in EXHIBIT D.

                                       21
<Page>

      (d)  Notwithstanding the provisions of subsections (a), (b) and (e) of
this Section, and subject to the provisions of Section 10.5 above, the cost of
any repairs shall be borne by Tenant, and Tenant shall not be entitled to rental
abatement or termination rights, if the damage is due to the fault or neglect of
Tenant or its employees, subtenants, invitees or representatives. In addition,
the provisions of this Section shall not be deemed to require Landlord to repair
any improvements or fixtures that Tenant is obligated to repair or insure
pursuant to any other provision of this Lease.

      (e)  Tenant shall fully cooperate with Landlord in removing Tenant's
personal property and any debris from the Premises to facilitate all inspections
of the Premises and the making of any repairs. Notwithstanding anything to the
contrary contained in this Lease, if Landlord in good faith believes there is a
risk of injury to persons or damage to property from entry into the Building or
Premises following any damage or destruction thereto, Landlord may restrict
entry into the Building or the Premises by Tenant, its employees, agents and
contractors in a non-discriminatory manner, without being deemed to have
violated Tenant's rights of quiet enjoyment to, or made an unlawful detainer of,
or evicted Tenant from, the Premises. Upon request, Landlord shall consult with
Tenant to determine if there are safe methods of entry into the Building or the
Premises solely in order to allow Tenant to retrieve files, data in computers,
and necessary inventory, subject however to all indemnities and waivers of
liability from Tenant to Landlord contained in this Lease and any additional
indemnities and waivers of liability which Landlord may require.

   SECTION 11.2 LEASE GOVERNS. Tenant agrees that the provisions of this Lease,
including without limitation Section 11.1, shall govern any damage or
destruction and shall accordingly supersede any contrary statute or rule of law.

                          ARTICLE XII. EMINENT DOMAIN

   SECTION 12.1 TOTAL OR PARTIAL TAKING. If all or a material portion of the
Premises is taken by any lawful authority by exercise of the right of eminent
domain, or sold to prevent a taking, either Tenant or Landlord may terminate
this Lease effective as of the date possession is required to be surrendered to
the authority. In the event title to a portion of the Building or Project, other
than the Premises, is taken or sold in lieu of taking, and if Landlord elects to
restore the Building in such a way as to alter the Premises materially, either
party may terminate this Lease, by written notice to the other party, effective
on the date of vesting of title. In the event neither party has elected to
terminate this Lease as provided above, then Landlord shall promptly, after
receipt of a sufficient condemnation award, proceed to restore the Premises to
substantially their condition prior to the 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 is deprived on account of the
taking and restoration. In the event of a taking, Landlord shall be entitled to
the entire amount of the condemnation award without deduction for any estate or
interest of Tenant; provided that nothing in this Section shall be deemed to
give Landlord any interest in, or prevent Tenant from seeking any award against
the taking authority for, the taking of personal property and fixtures belonging
to Tenant or for relocation or business interruption expenses recoverable from
the taking authority.

                                       22
<Page>

   SECTION 12.2 TEMPORARY TAKING. No temporary taking of the Premises shall
terminate this Lease or give Tenant any right to abatement of rent, and any
award specifically attributable to a temporary taking of the Premises shall
belong entirely to Tenant. A temporary taking shall be deemed to be a taking of
the use or occupancy of the Premises for a period of not to exceed one hundred
eighty (180) days.

   SECTION 12.3 TAKING OF PARKING AREA. In the event there shall be a taking of
the parking area such that Landlord can no longer provide sufficient parking to
comply with this Lease, Landlord may substitute reasonably equivalent parking in
a location reasonably close to the Building; provided that if Landlord fails to
make that substitution within one hundred eighty (180) days following the taking
and if the taking materially impairs Tenant's use and enjoyment of the Premises,
Tenant may, at its option, terminate this Lease by written notice to Landlord.
If this Lease is not so terminated by Tenant, there shall be no abatement of
rent and this Lease shall continue in effect

         ARTICLE XIII. SUBORDINATION; ESTOPPEL CERTIFICATE; FINANCIALS

   SECTION 13.1 SUBORDINATION. At the option of Landlord, this Lease shall be
either superior or subordinate to all, ground or underlying leases, mortgages
and deeds of trust, if any, which may hereafter affect the Building, and to all
renewals, modifications, consolidations, replacements and extensions thereof
provided, that so long as Tenant is not in default under this Lease, this Lease
shall not be terminated or Tenant's quiet enjoyment of the Premises disturbed in
the event of termination of any such ground or underlying lease, or the
foreclosure of any such mortgage or deed of trust, to which Tenant has
subordinated this Lease pursuant to this Section. In the event of a termination
or foreclosure, Tenant shall become a tenant of and attorn to the
successor-in-interest to Landlord upon the same terms and conditions as are
contained in this Lease, and shall execute any instrument reasonably required by
Landlord's successor for that purpose. Tenant shall also, upon written request
of Landlord, execute and deliver all instruments as may be required from time to
time to subordinate the rights of Tenant under this Lease to any ground or
underlying lease or to the lien of any mortgage or deed of trust (provided that
such instruments include the nondisturbance and attornment provisions set forth
above), or, if requested by Landlord, to subordinate, in whole or in part, any
ground or underlying lease or the lien of any mortgage or deed of trust to this
Lease.

   SECTION 13.2 ESTOPPEL CERTIFICATE.

      (a)  Tenant shall, at any time upon not less than ten (10) days prior
written notice from Landlord, execute, acknowledge and deliver to Landlord, in
any form that Landlord may reasonably require, a statement in writing (i)
certifying that this Lease is unmodified and in full force and effect (or, if
modified, stating the nature of the modification and certifying that this Lease,
as modified, is in full force and effect) and the dates to which the rental,
additional rent and other charges have been paid in advance, if any, and (ii)
acknowledging that, to Tenant's knowledge, there are no uncured defaults on the
part of Landlord, or specifying each default if any are claimed, and (iii)
setting forth all further information that Landlord may reasonably require.
Tenant's statement may be relied upon by any prospective purchaser or
encumbrancer of all or any portion of the Building or Project.

                                       23
<Page>

      (b)  Notwithstanding any other rights and remedies of Landlord, Tenant's
failure to deliver any estoppel statement within the provided time shall be
conclusive upon Tenant that (i) this Lease is in full force and effect, without
modification except as may be represented by Landlord, (ii) there are no uncured
defaults in Landlord's performance, and (iii) not more than one month's rental
has been paid in advance.

   SECTION 13.3 FINANCIALS.

      (a)  Tenant shall deliver to Landlord, prior to the execution of this
Lease and thereafter at anytime upon Landlord's request, Tenant's current tax
returns and financial statements, certified true, accurate and complete by the
chief financial officer of Tenant, including a balance sheet and profit and loss
statement for the most recent prior year (collectively, the "Statements"), which
Statements shall accurately and completely reflect the financial condition of
Tenant. Landlord agrees that it will keep the Statements confidential, except
that Landlord shall have the right to deliver the same to any proposed purchaser
of the Building or Project, and to any encumbrancer of all or any portion of the
Building or Project.

      (b)  Tenant acknowledges that Landlord is relying on the Statements in its
determination to enter into this Lease, and Tenant represents to Landlord, which
representation shall be deemed made on the date of this Lease and again on the
Commencement Date, that no material change in the financial condition of Tenant,
as reflected in the Statements, has occurred since the date Tenant delivered the
Statements to Landlord. The Statements are represented and warranted by Tenant
to be correct and to accurately and fully reflect Tenant's true financial
condition as of the date of submission by any Statements to Landlord.

                       ARTICLE XIV. DEFAULTS AND REMEDIES

   SECTION 14.1 TENANT'S DEFAULTS. In addition to any other event of default set
forth in this Lease, the occurrence of any one or more of the following events
shall constitute a default by Tenant:

      (a)  The failure by Tenant to make any payment of rent or additional rent
required to be made by Tenant, as and when due, where the failure continues for
a period of three (3) days after written notice 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
and 1161(a) as amended. For purposes of these default and remedies provisions,
the term "additional rent" shall be deemed to include all amounts of any type
whatsoever other than Basic Rent to be paid by Tenant pursuant to the terms of
this Lease.

      (b)  Assignment; sublease, encumbrance or other transfer of the Lease by
Tenant, either voluntarily or by operation of law, whether by judgment,
execution, transfer by intestacy or testacy, or other means, without the prior
written consent of Landlord.

      (c)  The discovery by Landlord that any financial statement provided by
Tenant, or by any affiliate, successor or guarantor of Tenant, was materially
false.

      (d)  The failure of Tenant to timely and fully provide any subordination
agreement, estoppel certificate or financial statements in accordance with the
requirements of Article XIII.

                                       24
<Page>

      (e)  The failure or inability 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 any other subsection of this
Section, where the failure continues for a period of thirty (30) days after
written notice from Landlord to Tenant or such shorter period as is specified in
any other provision of this Lease; 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 and 1161(a) as amended. However, if the nature
of the failure 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
commences the cure within thirty (30) days, and thereafter diligently pursues
the cure to completion.

      (f)  (i) The making by Tenant of any general assignment for the benefit of
creditors; (ii) the filing by or against Tenant of a petition to have Tenant
adjudged a Chapter 7 debtor under the Bankruptcy Code or to have debts
discharged 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 (30) days); (iii) the appointment of a
trustee or receiver to take possession of substantially all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease, if possession is
not restored to Tenant within thirty (30) days; (iv) the attachment, execution
or other judicial seizure of substantially all of Tenants assets located at the
Premises or of Tenant's interest in this Lease, where the seizure is not
discharged within thirty (30) days; or (v) Tenant's convening of a meeting of
its creditors for the purpose of effecting a moratorium upon or composition of
its debts. Landlord shall not be deemed to have knowledge of any event described
in this subsection unless notification in writing is received by Landlord, nor
shall there be any presumption attributable to Landlord of Tenant's insolvency.
In the event that any provision of this subsection is contrary to applicable
law, the provision shall be of no force or effect.

   SECTION 14.2 LANDLORD'S REMEDIES.

      (a)  In the event of any default by Tenant, or in the event of the
abandonment of the Premises by Tenant, then in addition to any other remedies
available to Landlord, Landlord may exercise the following remedies:

           (i)  Landlord may terminate Tenant's right to possession of the
Premises by any lawful means, in which case this Lease shall terminate and
Tenant shall immediately surrender possession of the Premises to Landlord. Such
termination shall not affect any accrued obligations of Tenant under this Lease.
Upon termination, Landlord shall have the right to reenter the Premises and
remove all persons and property. Landlord shall also be entitled to recover from
Tenant:

                (1)  The worth at the time of award of the unpaid rent and
additional rent which had been earned at the time of termination;

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

                                       25
<Page>

                (3)  The worth at the time of award of the amount by which the
unpaid rent and additional rent for the balance of the Tern after the time of
award exceeds the amount of such loss that Tenant proves could be reasonably
avoided;

                (4)  Any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which in the ordinary course of things would be likely to
result from Tenant's default, including, but not limited to, the cost of
recovering possession of the Premises, refurbishment of the Premises, marketing
costs, commissions and other expenses of reletting, including necessary repair,
the unamortized portion of any tenant improvements and brokerage commissions
funded by Landlord in connection with this Lease, reasonable attorneys' fees,
and any other reasonable costs; and

                (5)  At Landlord's election, all other amounts in addition to or
in lieu of the foregoing as may be permitted by law. The term "rent" as used in
this Lease shall be deemed to mean the Basic Rent and all other sums required to
be paid by Tenant to Landlord pursuant to the terms of this Lease. Any sum,
other than Basic Rent, shall be computed on the basis of the average monthly
amount accruing daring the twenty-four (24) month period immediately prior to
default, except that if it becomes necessary to compute such rental before the
twenty-four (24) month period has occurred, then the computation shall be on the
basis of the average monthly amount during the shorter period. As used in
subparagraphs (1) and (2) above, the "worth at the time of award" shall be
computed by allowing interest at the rate often percent (10%) per annum. As used
in subparagraph (3) above, the "worth at the time of award" shall be computed by
discounting the amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%).

           (ii) Landlord may elect not to terminate Tenant's right to possession
of the Premises, in which event Landlord may continue to enforce all of its
rights and remedies under this Lease, including the right to collect all rent as
it becomes due. Efforts by the Landlord to maintain, preserve or relet the
Premises, or the appointment of a receiver to protect the Landlord's interests
under this Lease, shall not constitute a termination of the Tenant's right to
possession of the Premises. In the event that Landlord elects to avail itself of
the remedy provided by this subsection (ii), Landlord shall not unreasonably
withhold its consent to an assignment or subletting of the Premises subject to
the reasonable standards for Landlord's consent as are contained in this Lease.

      (b)  Landlord shall be under no obligation to observe or perform any
covenant of this Lease on its part to be observed or performed which accrues
after the date of any default by Tenant unless and until the default is cured by
Tenant, it being understood and agreed that the performance by Landlord of its
obligations under this Lease are expressly conditioned upon Tenant's full and
timely performance of its obligations under this Lease. The various fights and
remedies reserved to Landlord in this Lease or otherwise shall be cumulative
and, except as otherwise provided by California law, Landlord may pursue any or
all of its rights and remedies at the same time.

      (c)  No delay or omission of Landlord to exercise any right or remedy
shall be construed as a waiver of the right or remedy or of any default by
Tenant. The acceptance by

                                       26
<Page>

Landlord of rent shall not be a (i) waiver of any preceding breach or default by
Tenant of any provision of this Lease, other than the failure of Tenant to pay
the particular rent accepted, regardless of Landlord's knowledge of the
preceding breach or default at the time of acceptance of rent, or (ii) a waiver
of Landlord's right to exercise any remedy available to Landlord by virtue of
the breach or default. The acceptance of any payment from a debtor in
possession, a trustee, a receiver or any other person acting on behalf of Tenant
or Tenant's estate shall not waive or cure a default under Section 14.1. No
payment by Tenant or receipt by Landlord of a lesser amount than the rent
required by this Lease shall be deemed to be other than a partial payment on
account of the earliest due stipulated rent, nor shall any endorsement or
statement on any check or letter be deemed an accord and satisfaction and
Landlord shall accept the check or payment without prejudice to Landlord's right
to recover the balance of the rent or pursue any other remedy available to it.
No act or thing done by Landlord or Landlord's agents during the Term shall be
deemed an acceptance of a surrender of the Premises, and no agreement to accept
a surrender shall be valid unless in writing and signed by Landlord. No employee
of Landlord or of Landlord's agents shall have any power to accept the keys to
the Premises prior to the termination of this Lease, and the delivery of the
keys to any employee shall not operate as a termination of the Lease or a
surrender of the Premises.

   SECTION 14.3 LATE PAYMENTS.

      (a)  Any rent due under this Lease that is not received by Landlord within
five (5) days of the date when due shall bear interest at the maximum rate
permitted by law from the date due until fully paid. The payment of interest
shall not cure any default by Tenant under this Lease. In addition, Tenant
acknowledges that the late payment by Tenant to Landlord of rent will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of
which will be extremely difficult and impracticable to ascertain. Those costs
may include, but are not limited to, administrative, processing and accounting
charges, and late charges which may be imposed on Landlord by the terms of any
ground lease, mortgage or trust deed covering the Premises. Accordingly, if any
rent due from Tenant shall not be received by Landlord or Landlord's designee
within five (5) days after the date due, then Tenant shall pay to Landlord, in
addition to the interest provided above, a late charge in a sum equal to the
greater of five percent (5%) of the amount overdue or Two Hundred Fifty Dollars
($250.00) for each delinquent payment. Acceptance of a late charge by Landlord
shall not constitute a waiver of Tenant's default with respect to the overdue
amount, nor shall it prevent Landlord from exercising any of its other rights
and remedies.

      (b)  Following each second consecutive installment of rent that is not
paid within five (5) days following notice of nonpayment from Landlord, Landlord
shall have the option (i) to require that beginning with the first payment of
rent next due, rent shall no longer be paid in monthly installments but shall be
payable quarterly three (3) months in' advance and/or (ii) to require that
Tenant increase the amount, if any, of the Security Deposit by one hundred
percent (100%). Should Tenant deliver to Landlord, at any time during the Term,
two (2)or more insufficient checks, the Landlord may require that all monies
then and thereafter due from Tenant be paid to Landlord by cashier's check.

   SECTION 14.4 RIGHT OF LANDLORD TO PERFORM. All covenants and agreements to be
performed by Tenant under this Lease shall be performed at Tenant's sole cost

                                       27
<Page>

and expense and without any abatement of rent or right of set-off. If Tenant
fails to pay any sum of money, other than rent, or fails to perform any other
act on its part to be performed under this Lease, and the failure continues
beyond any applicable grace period set forth in Section 14.1, then in addition
to any other available remedies, Landlord may, at its election make the payment
or perform the other act on Tenant's part. Landlord's election to make the
payment or perform the act on Tenant's part shall not give rise to any
responsibility of Landlord to continue making the same or similar payments or
performing the same or similar acts. Tenant shall, promptly upon demand by
Landlord, reimburse Landlord for all sums paid by Landlord and all necessary
incidental costs, together with interest at the maximum rate permitted by law
from the date of the payment by Landlord. Landlord shall have the same rights
and remedies if Tenant fails to pay those amounts as Landlord would have in the
event of a default by Tenant in the payment of rent.

   SECTION 14.5 DEFAULT BY LANDLORD. Landlord shall not be deemed to be in
default in the performance of any obligation under this Lease unless and until
it has failed to perform the obligation within thirty (30) days after written
notice by Tenant to Landlord specifying in reasonable detail the nature and
extent of the failure; provided, however, that if the nature of Landlord's
obligation is such that more than thirty (30) days are required for its
performance, then Landlord shall not be deemed to be in default if it commences
performance within the thirty (30) day period and thereafter diligently pursues
the cure to completion.

   SECTION 14.6 EXPENSES AND LEGAL FEES. All sums reasonably incurred by
Landlord in connection with any event of default by Tenant under this Lease or
holding over of possession by Tenant after the expiration or earlier termination
of this Lease, including without limitation all costs, expenses and actual
accountants, appraisers, attorneys and other professional fees, and any
collection agency or other collection charges, shall be due and payable by
Tenant to Landlord on demand, and shall bear interest at the rate often percent
(10%) per annum. Should either Landlord or Tenant bring any action in connection
with this Lease, the prevailing party shall be entitled to recover as a part of
the action its reasonable attorneys' fees, and all other costs. The prevailing
party for the purpose of this paragraph shall be determined by the trier of the
facts.

   SECTION 14.7 WAIVER OF JURY TRIAL. LANDLORD AND TENANT EACH ACKNOWLEDGES THAT
1T IS AWARE OF AND HAS HAD THE ADVICE OF COUNSEL OF ITS CHOICE WITH RESPECT TO
ITS RIGHTS TO TRIAL BY JURY, AND EACH PARTY DOES HEREBY EXPRESSLY AND KNOWINGLY
WAIVE AND RELEASE ALL SUCH RIGHTS TO TRIM. BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM BROUGHT BY EITHER PARTY HERETO AGAINST THE OTHER (AND/OR AGAINST
ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR SUBSIDIARY OR AFFILIATED
ENTITIES) ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH
THIS LEASE, TENANT'S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM OF
INJURY OR DAMAGE.

   SECTION 14.8 SATISFACTION OF JUDGMENT. The obligations of Landlord do not
constitute the personal obligations of the individual partners, trustees,
directors, officers or shareholders of Landlord or its constituent partners.
Should Tenant recover a money judgment against Landlord, such judgment shall be
satisfied only out of the proceeds of sale received upon

                                       28
<Page>

execution of such judgment and levied thereon against the right, title and
interest of Landlord in the Project and out of the rent or other income from
such property receivable by Landlord or out of consideration received by
Landlord from the sale or other disposition of all or any part of Landlord's
right, title or interest in the Project and no action for any deficiency may be
sought or obtained by Tenant.

   SECTION 14.9 LIMITATION OF ACTIONS AGAINST LANDLORD. Any claim, demand or
right of any kind by Tenant which is based upon or arises in connection with
this Lease shall be barred unless Tenant commences an action thereon within
twelve (12) months after the date that the act, omission, event or default upon
which the claim, demand or right arises, has occurred.

                            ARTICLE XV. END OF TERM

   SECTION 15.1 HOLDING OVER. This Lease shall terminate without further notice
upon the expiration of the Term, and any holding over by Tenant after the
expiration shall not constitute a renewal or extension of this Lease, or give
Tenant any rights under this Lease, except when in writing signed by both
parties. If Tenant holds over for any period after the expiration (or earlier
termination) of the Term without the prior written consent of Landlord, such
possession shall constitute a tenancy at sufferance only; such holding over with
the prior written consent of Landlord shall constitute a month-to-month tenancy
commencing on the first (1st) day following the termination of this Lease. In
either of such events, possession shall be subject to all of the temps of this
Lease, except that the monthly Basic Rent shall be the greater of (a) two
hundred percent (200%) of the Basic Rent for the month immediately preceding the
date of termination or (b) the then currently scheduled Basic Rent for
comparable space in the Building. 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 claims made by any succeeding tenant relating to such
failure to surrender. Acceptance by Landlord of rent after the termination shall
not constitute a consent to a holdover or result in a renewal of this Lease. The
foregoing provisions of this Section are addition to and do not affect
Landlord's right of re-entry or any other rights of Landlord under this Lease or
at law.

   SECTION 15.2 MERGER ON TERMINATION. The voluntary or other surrender of this
Lease by Tenant, or a mutual termination of this Lease, shall terminate any or
all existing subleases unless Landlord, at its option, elects in writing to
treat the surrender or termination as an assignment to it of any or all
subleases affecting the Premises.

   SECTION 15.3 SURRENDER OF PREMISES; REMOVAL OF PROPERTY. Upon the Expiration
Date or upon any earlier termination of this Lease, Tenant shall quit and
surrender possession of the Premises to Landlord in as good order, condition and
repair as when received or as hereafter maybe improved by Landlord or Tenant,
reasonable wear and tear and repairs which are Landlord's obligation excepted,
and shall, without expense to Landlord, remove or cause to be removed from the
Premises all personal property and debris, except for any items that Landlord
may by written authorization allow to remain. Tenant shall repair all damage to
the Premises resulting from the removal, which repair shall include the patching
and filling of holes and repair of structural damage, provided that Landlord may
instead elect to repair any

                             LANDLORD'S DISCLOSURES

                                    SPECTRUM

      The capitalized terms used and not otherwise defined in this Exhibit shall
have the same definitions as set forth in the Lease. The provisions of this
Exhibit shall supersede any inconsistent or conflicting provisions of the Lease.

      1.   Landlord has been informed that the El Toro Marine Corps Air Station
(MCAS) has been listed as a Federal Superfund site as a result of chemical
releases occurring over many years of occupancy. Various chemicals including jet
fuel, motor oil and solvents have been discharged in several areas throughout
the MCAS site. A regional study conducted by the Orange County Water District
has estimated that groundwaters beneath more than 2,900 acres have been impacted
by Trichloroethlene (TCE), an industrial solvent. There is a potential that this
substance may have migrated into the ground water underlying the Premises. The
U.S. Environmental Protection Agency, the Santa Ana Region Quality Control
Board, and the Orange County Health Care Agency are overseeing the
investigation/cleanup of this contamination. To the Landlord's current actual
knowledge, the ground water in this area is used for irrigation purposes only,
and there is no practical impediment to the use or occupancy of the Premises due
to the El Toro discharges.

           amount of Thirteen Thousand Twenty-Eight Dollars ($13,028.00) each
           upon the expiration of the twelfth (12th), twenty-fourth (24th) and
           thirty-sixth (36th) months of the Term."

                                   WORK LETTER

                                DOLLAR ALLOWANCE
                            [SECOND GENERATION SPACE]

The Tenant Improvement work (herein "Tenant improvements") shall consist of any
work required to complete Suite 100 pursuant to approved plans and
specifications. All of the Tenant Improvement work shall be performed by a
contractor selected by Landlord and in accordance with the procedures and
requirements set forth below.

I.    ARCHITECTURAL AND CONSTRUCTION PROCEDURES

      A.   Tenant and Landlord have approved, or shall approve within the time
           period set forth below, both (i) a detailed space plan for Suite 100,
           prepared by Landlord's architect, which includes interior partitions,
           ceilings. interior finishes, interior office doors, suite entrance,
           floor coverings, window coverings, lighting, electrical and telephone
           outlets, plumbing connections, heavy floor loads and other special
           requirements ("Preliminary Plan"), and (ii) an estimate, prepared by
           Landlord's contractor, of the cost for which Landlord will complete
           or cause to be completed the Tenant Improvements ("Preliminary Cost
           Estimate"). Tenant shall approve or disapprove each of the
           Preliminary Plan and the Preliminary Cost Estimate by signing copies
           of the appropriate instrument and delivering same to Landlord within
           five (5) working days of its receipt by Tenant. If Tenant disapproves
           any matter, Tenant shall specify in detail the reasons for
           disapproval and Landlord shad attempt to modify the Preliminary Plan
           and the Preliminary Cost Estimate to incorporate Tenants suggested
           revisions in a mutually satisfactory manner. In no event, however,
           shad Tenant have the right to make additions to the Preliminary Plan
           as part of its approval thereof which would increase the improvements
           to be paid for by "Landlord's Contribution" (as hereinafter defined),
           it being understood and agreed that the Preliminary Plan submitted by
           Landlord's architect is intended to include all Improvements desired
           by Tenant using Landlord's "Standards" (as hereinafter defined),
           whether or not the full amount of Landlord's Contribution would be
           required to complete construction of the improvements as shown in the
           Preliminary Plan. In all events, however, Tenant shall approve in all
           respects a Preliminary Plan and Preliminary Cost Estimate not later
           than August 2, 2000 ("Plan Approval Date"), it being understood that
           Tenant's failure to do so shad constitute a "Tenant Delay" for
           purposes of this Lease.

      B.   On or before the Plan Approval Date, Tenant shall provide in writing
           to Landlord or Landlords architect all specifications and Information
           requested by Landlord for the preparation of final construction
           documents and costing, including without limitation Tenant's final
           selection of wall and floor finishes, complete specifications and
           locations (including load and HVAC requirements) of Tenant's

                                        1
<Page>

           equipment, and details of all "Non-Standard Improvements" (as defined
           below) to be Installed in Suite 100 (collectively, "Programming
           Information"). Tenants failure to provide the Programming Information
           by the Plan Approval Date shall constitute a Tenant Delay for
           purposes of this Lease. Tenant understands that final construction
           documents for the Tenant Improvements shall be predicated on the
           Programming Information, and accordingly that such Information must
           be accurate and complete.

      C.   The Tenant Improvements shall incorporate Landlords building standard
           materials and specifications ("Standards"). No deviations from the
           Standards may be required by Tenant with respect to doors and frames,
           finish hardware, entry graphics, the ceiling system, fight fixtures
           and switches, mechanical systems, life and safety systems, and/or
           window coverings; provided that Landlord may, in its sole discretion,
           authorize in writing one or more of such deviations, in which event
           Tenant shall pay to Landlord, prior to the commencement of
           construction and in addition to sums otherwise due hereunder from
           Tenant, an amount equal to the cost, as reasonably estimated by
           Landlord, of replacing the deviating item(s) with the applicable
           Standard Item(s) upon the expiration or termination of this Lease. Ad
           other non-standard items ("Nonstandard Improvements") shall be
           subject to the reasonable prior approval of Landlord. Landlord shall
           in no event be required to approve any Non-Standard Improvement if
           Landlord determines that such improvement (i) is of a lesser quality
           than the corresponding Standard, (ii) fails to conform to applicable
           governmental requirements, (iii) requires budding services beyond the
           level normally provided to other tenants, (v) would delay
           construction of the Tenant Improvements beyond the Estimated
           Commencement Date for Suite 100 and Tenant declines to accept such
           delay in writing as a Tenant Delay, or (v) would have an adverse
           aesthetic impact, from the exterior of Suite 100.

      D.   Upon Tenant's approval of the Preliminary Plan and Preliminary Cost
           Estimate and delivery of the complete Programming Information,
           Landlord's architect and engineers shall prepare and deliver to
           Tenant working drawings and specifications ("Working Drawings and
           Specifications"), and Landlord's contractor shall prepare a final
           construction cost estimate ("Final Cost Estimate') for the Tenant
           Improvements in conformity with the Working Drawings and
           Specifications. Tenant shall have five (5) working days from the
           receipt thereof to approve or disapprove the Working Drawings and
           Specifications and the Final Cost Estimate. Tenant shall not
           unreasonably withhold or delay its approval, and any disapproval or
           requested modification shall be limited to items not contained in the
           approved Preliminary Plan or Preliminary Cost Estimate. In no event
           shall Tenant disapprove the Final Cost Estimate if it does not exceed
           the approved Preliminary Cost Estimate. Should Tenant disapprove the
           Working Drawings and Specifications and the Final Cost Estimate, such
           disapproval shall be accompanied by a detailed list of revisions. Any
           revision requested by Tenant and accepted by Landlord shall be
           incorporated into a revised set of Working Drawings and
           Specifications and Final Cost Estimate, and Tenant shall approve

                                       2
<Page>

           same in writing within rive (5) business days of receipt without
           further revision. Tenant's failure to comply in a timely manner with
           any of the requirements of this paragraph shall constitute a Tenant
           Delay. Without limiting the rights of Landlord for Tenant Delays as
           set forth herein, in the event Tenant has not approved both the
           Working Drawings and Specifications and the Final Cost Estimate
           within sixty (60) days following the date of this Amendment, then
           Landlord may, at its option, elect to terminate this Lease by written
           notice to Tenant in the event Landlord elects to effect such a
           termination, Tenant shall, within ten (10) days following demand by
           Landlord, pay to Landlord any costs incurred by Landlord in
           connection with the preparation or review of plans, construction
           estimates, price quotations, drawings or specifications under this
           Work Letter and for all costs incurred in the preparation and
           execution of this Amendment. Including any leasing commissions.

      E.   In the event that Tenant requests in writing a revision in the
           approved Working Drawings and Specifications ("Change"), Landlord
           shall advise Tenant by written change order as soon as is practical
           of any increase in the Completion Cost and/or any Tenant Delay such
           Change would cause. Tenant shall approve or disapprove such change
           order in writing within two (2) working days following its receipt
           from Landlord. Tenant's approval of a Change shall be accompanied by
           Tenant's payment of any resulting increase in the Completion Cost
           Landlord shall have the right to decline Tenant's request for a
           Change for any of the reasons set forth in Article I.C. above for
           Landlord's disapproval of a Non-Standard Improvement. It is
           understood that Landlord shall have no obligation to interrupt or
           modify the Tenant Improvement work pending Tenant's approval of a
           change order.

      F.   Notwithstanding any provision in the Lease to the contrary, if Tenant
           fails to comply with any of the time periods specified in this Work
           Letter, fails otherwise to approve or reasonably disapprove any
           submittal within five (5) working days, fails to approve in writing
           both the Preliminary Plan and Preliminary Cost Estimate for the
           Tenant Improvements by the Plan Approval Date, fails to provide all
           of the Programming Information requested by Landlord by the Plan
           Approval Date, fails to approve in writing the Working Drawings and
           Specifications and the Final Cost Estimate within the time provided
           herein, requests any Changes, furnishes inaccurate or erroneous
           specifications or other information, or otherwise delays in any
           manner the completion of the Tenant Improvements (including without
           limitation by specifying materials that are not readily available) or
           the issuance of an occupancy certificate (any of the foregoing being
           referred to in this Lease as a "Tenant Delay"), then Tenant shall
           bear any resulting additional construction cost or other expenses,
           and the Commencement Date for Suite 100 shall be deemed to have
           occurred for off purposes, including Tenant's obligation to pay rent,
           as of the date Landlord reasonably determines that it would have been
           able to deliver Suite 100 to Tenant but for the collective Tenant
           Delays. In no event, however, shall such date be earlier than the
           Estimated Commencement Date for Suite 100 set forth in the Basic
           Lease Provisions. Should Landlord determine that the Commencement
           Date for Suite 100 should be advanced in

                                        3
<Page>

           accordance with the foregoing, it shall so notify Tenant in writing.
           Landlord's determination shall be conclusive unless Tenant notifies
           Landlord in writing, within five (5) working days thereafter, of
           Tenant's election to contest same by arbitration with JAMS/ENDISPUTE
           in Orange County, California. Pending the outcome of such arbitration
           proceedings, Tenant shall make timely payment of all rent due under
           this Lease based upon the Commencement Date set forth in the
           aforesaid notice from Landlord.

      G.   Landlord shall permit Tenant and its agents to enter Suite 100 prior
           to the Commencement Date for Suite 100 In order that Tenant may
           perform any work to be performed by Tenant hereunder through its own
           contractors, subject to Landlord's prior written approval, and In a
           manner and upon terms and conditions and at times satisfactory to
           Landlord's representative. The foregoing license to enter Suite 100
           prior to the Commencement Date for Suite 100 is, however, conditioned
           upon Tenant's contractors and their subcontractors and employees
           working in harmony and not interfering with the work being performed
           by Landlord. If at any time that entry shall cause disharmony or
           interfere with the work being performed by Landlord, this license may
           be withdrawn by Landlord upon twenty-four (24) hours written notice
           to Tenant. That license is further conditioned upon the compliance by
           Tenant's contractors with all requirements imposed by Landlord on
           third party contractors and subcontractors,
