Real Property, the Personal Property and the Intangibles (collectively, the
"Property") to Buyer, and Buyer is prepared to purchase and accept the Property
from Seller, all for the purchase price and on the other terms and conditions
hereinafter set forth.

                                   AGREEMENT:

         In consideration of the mutual covenants and agreements herein
contained, and intending to be legally bound hereby, the parties hereto agree as
follows:

         1.       Sale and Purchase. Seller hereby agrees to sell and convey the
Property to Buyer and Buyer hereby agrees to purchase and accept the Property
from Seller, in each case for the Purchase Price and subject to the other terms
and conditions set forth in this Agreement.

         2.       Purchase Price. The purchase price for the Property (the
"Purchase Price") shall be Sixty Five Million Four Hundred Thirty Three Thousand
Four Hundred Eighty Two and no/100 Dollars ($65,433,482.00). The Purchase Price
shall be paid to Seller by Buyer as follows:

                  2.1      Deposit. Within two (2) Working Days (a "Working Day"
shall be deemed to be any day that is not a Saturday or Sunday or an official
state or federal holiday in California) after the Effective Date, Buyer shall
deposit with First American Title Guaranty Company, located at 1737 North First
Street, Suite 100, San Jose, California, 95112 (telephone (408) 451-7800; fax
(408) 451-7836; Attention: Rob Tidd) (the "Escrow Agent"), to be held in an
interest-bearing escrow account under escrow account No. 4305-521802sc (the
"Escrow") and disbursed in accordance with this Agreement, a cash deposit in the
amount of One Million and no/100 Dollars ($1,000,000.00) (which amount, together
with all interest earned thereon while in the Escrow, shall be hereinafter
collectively referred to as the "Initial Deposit"). If Buyer fails to remit the
Initial Deposit into Escrow within such two (2) Working Day Period, Seller shall
be entitled to terminate this Agreement by providing written notice of such
termination to Buyer. If Buyer elects to proceed with the transaction in
accordance with Section 5.2.1, below, then on or before the expiration of the
Feasibility Period (as defined below), Buyer shall deposit an additional Two
Million and no/100 Dollars ($2,000,000.00) into Escrow (which amount, together
with all interest earned thereon while in the Escrow, shall be hereinafter
collectively referred to as the "Additional Deposit", and collectively with the
Initial Deposit, the "Deposit").

                  2.2      Disposition of Deposit. The Initial Deposit shall be
fully refunded out of Escrow to Buyer, without requirement of the consent or
release by Seller, and thereafter neither party shall have any further liability
hereunder except as may otherwise be expressly provided hereunder if Buyer
elects to unilaterally terminate this Agreement during the Feasibility Period,
as set forth in Section 5.2 below. If Buyer deposits the Additional Deposit
prior to the expiration of the Feasibility Period, then the Deposit shall be
deemed non-refundable to Buyer except as expressly provided herein. The Deposit
shall be applied to the Purchase Price at the Closing.

                  2.3      Interest. The Deposit shall be deposited to Escrow in
the form of cash, certified check, bank cashier's check, wire transfer or other
form of readily available federally insured funds. The Deposit shall be held by

interest-bearing account or in such other liquid investment as reasonably may be
requested by Buyer and approved by Seller in its reasonable discretion. All
interest earned on the Deposit shall be deemed to be part of the Deposit and
shall accrue to the benefit of Buyer except to the extent the Deposit becomes
payable to Seller pursuant to Section 11.1. In such event, Seller shall be
entitled to all interest earned on the Deposit.

                  2.4      Remainder of Purchase Price. At Closing, Buyer shall
deliver to the Escrow Agent cash in an amount equal to the Purchase Price, less
the Deposit, together with Buyer's share of closing costs and due and payable by
Buyer in accordance with this Agreement, and subject to adjustments, prorations
and apportionments as set forth herein. The Purchase Price shall be paid at the
Closing by wire transfer of immediately available federal funds, transferred
through the Escrow to the order or account of Seller or such other person as
Seller may designate in writing.

         3.       Seller's Representations and Warranties; Definition of
Seller's Knowledge; Survival.

                  3.1      Seller's Representations and Warranties. Seller
represents to Buyer as follows, which representations and warranties shall be
deemed remade by Seller to Buyer on the Closing Date, and which shall survive
the Closing for the period and to the extent described in Section 3.3 below:

                           3.1.1    Compliance with Laws. To the best of
Seller's knowledge, the Improvements were constructed in compliance with
applicable federal, state and local laws and regulations ("Laws").

                           3.1.2    Documents. To the best of Seller's
knowledge, all Property Documents (defined below) delivered or made available to
Buyer by Seller are true copies.

                           3.1.3    Possessory Rights. There are no leases or
other possessory rights of third parties in the Real Property except for (i) the
Office Lease dated June 19, 2003, between Seller and Magma Design Automation,
Inc. (the "Magma Lease"), and (ii) the Pedestrian Bridge Lease Agreement dated
September 18, 1998 between Seller and the Santa Clara Valley Water District (the
"Bridge Lease").

                           3.1.4    Litigation. To the best of Seller's
knowledge, there is no current litigation, claim, investigation or eminent
domain proceeding that may affect the Property or the transaction contemplated
by this Agreement.

                           3.1.5    Authority. Subject to Section 7.2.5, below,
Seller has the power and authority to enter into and to perform all of Seller's
obligations pursuant to this Agreement, and to purchase the Property on the
terms and conditions set forth herein. No consent of any third party is required
in order for Seller to perform any of its obligations hereunder.

                                       3
<PAGE>

                           3.1.6    No Conflict. This Agreement and Seller' sale
of the Property hereunder do not violate any material terms or provisions of any
contract to which Seller is a party

                           3.1.7    Hazardous Materials. To the best of Seller's
knowledge, no Hazardous Materials (as defined below) have been placed on, under
or about the Property by Seller in violation of any applicable Environmental
Laws (as defined in Section 6.6(b), below).

                           3.1.8    Personal Property. Subject to the rights of
the "Tenant" under the Magma Lease, Seller is the owner of the Personal
Property, the Personal Property is not subject to any liens, leases, claims,
interests or encumbrances, and Seller has the right to transfer the Personal
Property to Buyer.

                           3.1.9    Signage. To the best of Seller's knowledge,
no parties have any right to use the existing monument signage on the rooftop of
Building 5.

                  3.2      Definition of Seller's Knowledge. As used in this
Section 3, the phrase "to the best of Seller's knowledge" refers only to the
current actual knowledge of the Designated Individuals (as hereinafter defined)
of Seller, and shall not be construed, by imputation or otherwise, to refer to
the knowledge of Seller or any affiliate of Seller, or to any officer, agent,
consultant, representative or employee of Seller or any affiliate thereof or,
except to the limited extent described in this Section 3.2, to impose upon such
Designated Individuals any duty to investigate the matter to which such actual
knowledge, or the absence thereof, pertains. Seller makes no representation that
the Designated Individuals have read all or any of the Property Documents (as
defined in Section 4.2). As used herein, the term "Designated Individuals" shall
refer to Roger van Overbeek, Director, Real Estate and Site Services, and Steve
Joesten, Site Services Manager, and Seller represents and warrants to Buyer that
the Designated Individuals are the individuals currently employed by 3Com with
the most extensive personal knowledge of the Property. Except as described
above, Seller makes no representation or warranty as to the scope of any inquiry
made by the Designated Individuals to verify the matters referred to in Section
3.1 hereof.

                  3.3      Survival. The representations and warranties of
Seller set forth in this Section 3 shall be deemed to have been made as of, and
only as of, (a) the Effective Date and (b) the Closing. Such representations and
warranties shall survive for a period of three hundred sixty five (365) days
after the Closing. No claim for a breach of any representation or warranty of
Seller shall be actionable or payable if the breach in question results from or
is based on a condition, state of facts or other matter which was known to or
discovered by Buyer prior to Closing. Seller shall have no liability to Buyer
for a breach of any representation or warranty (i) unless the valid claims for
all such breaches collectively aggregate more than $25,000, in which event the
full amount of such valid claims shall be actionable, up to the amount specified
in Section 11.2 hereof, and (ii) unless written notice containing a description
of the specific nature of such breach shall have been given by Buyer to Seller
prior to the expiration of the applicable period specified in the first sentence
of this Section 3.3 and an action shall have been

                                       4
<PAGE>

commenced by Buyer against Seller within thirty (30) days after expiration
of such applicable period.

                  3.4      Updating Representations and Warranties. In the event
that any representation or warranty of Seller needs to be modified due to
changes since the Effective Date, Seller shall deliver to Buyer a certificate,
dated as of the date of Closing and executed on behalf of Seller by a duly
authorized officer thereof, identifying any representation or warranty which is
not, or no longer is, true and correct and explaining the state of facts giving
rise to the change. In no event shall Seller be liable to Buyer for, or be
deemed to be in default hereunder by reason of, any breach of representation or
warranty which results from any change that (i) occurs between the Effective
Date and the date of the Closing and (ii) is either not prohibited under the
terms of this Agreement or is beyond the reasonable control of Seller to
prevent; provided, however, that the occurrence of any change to a
representation and warranty by Seller under this Article 3 shall, if materially
adverse to Buyer, constitute the non-fulfillment of the condition set forth in
Section 7.1.1 hereof. If, despite changes or other matters described in such
certificate, the Closing occurs, Seller's representations and warranties set
forth in this Agreement shall be deemed to have been modified by all statements
made in such certificate. In no event shall this Section 3.4 relieve Seller of
liability, if any, for making a representation or warranty that was known by
Seller to be false at the time it was made.

         4.       Seller's Covenants and Agreements.

                  4.1      Contracts. Within three (3) Working Days after the
Effective Date, to the extent in Seller's possession Seller shall make available
for inspection by Buyer or deliver to Buyer copies of all service, equipment,
supply, maintenance or concession agreements entered into between Seller and
such service providers with respect to the Property (collectively, the
"Contracts"), provided that Seller shall not be required to provide Buyer with
or assign to Buyer any agreements between Seller and Washington Group
("Washington Group"), which provides property management services to Seller at
the Property and at other properties owned or operated by Seller. Buyer shall
give written notice to Seller prior to the expiration of the Feasibility Period
designating those Contracts, if any, which Buyer elects to continue after the
Closing, and such designated Contracts, if assignable by Seller in accordance
with their terms (collectively, the "Assigned Contracts"), shall be assigned to
Buyer at the Closing, and Buyer shall assume all obligations with respect
thereto arising from and after the Closing. Notwithstanding the preceding
sentence, Seller shall have no obligation to assign such Contracts to Buyer if
the Assigned Contracts are assignable only with the approval of the other party
or parties to the Assigned Contracts and if Seller is unable to obtain such
approval, or if any expense must be incurred or any other consideration paid as
a condition to such assignment, unless Buyer agrees to reimburse Seller for such
expense or payment. Seller shall terminate all Contracts that are not assigned
to and assumed by Buyer as of the Closing or, if Seller is unable to or
otherwise fails to terminate such Contracts, Seller shall be solely responsible
for performance of Seller's obligations thereunder and shall indemnify Buyer
against all claims with respect thereto.

material to Buyer's decision to purchase the Property. Buyer acknowledges and

Seller shall operate and maintain the Property in substantially its current
condition and repair as of the Effective Date, in accordance with its current
management standards and subject to normal wear and tear; provided that such

or other casualty event prior to the Closing, in accordance with Section 10.2
hereof. From and after the Effective Date Seller agrees not to remove any
Personal Property from the Property.

                  4.4      New Agreements. During the pendency of this
Agreement, Seller shall not execute any agreement affecting the ownership or
operation of the Property, or any portion thereof, if such lease, license or
other agreement will be binding on Buyer or the Property after Closing, without
Buyer's prior written approval, not to be unreasonably withheld (which approval
shall be deemed denied if not approved in writing within five (5) Working Days

                                       7
<PAGE>

following Seller's written request for approval), such approval not to be
unreasonably withheld. Notwithstanding the foregoing, in no event shall Seller
be entitled to enter into any lease for Buildings 1 through 4, and Seller shall
not enter into any amendment of the Magma Lease without Buyer's prior written
approval, not to be unreasonably withheld, and in connection with such approval
Buyer's legal counsel shall have the opportunity to review and comment on any
such lease or amendment. In the event Buyer approves any leases for Building 5
which are executed after the Effective Date, and in the event the Closing
occurs, Buyer shall pay for all costs associated with such leases, including
without limitation any and all leasing commissions, rental concessions and
tenant improvement expenses and/or allowances, to the extent such costs have
been approved in writing by Buyer prior to the Closing. Notwithstanding anything
else in this Agreement, Seller shall pay for all (a) leasing commissions due or
payable in connection with the Magma Lease, subject to the provisions of Section
9.1.6, below, and (b) leasing commissions, tenant improvement costs and
attorneys fees due or payable in connection with any other lease entered into
prior to the Closing unless such costs have been approved in writing by Buyer
prior to the Closing.

                  4.5      Seller Obligations.

                           4.5.1    Seller agrees that, during the period
commencing on the Effective Date and until this Agreement is either terminated
or the parties proceed to Closing, Seller will remove its listing for the sale
of the Property and all advertisements related thereto and shall not show the
Property to or negotiate with other potential buyers of the Property, or
otherwise solicit offers or discuss the terms of a proposed sale of the Property
with other potential buyers; provided, however, that Seller shall not be deemed
to have breached this Section 4.5.1 if any advertisements placed prior to the
Effective Date continue in circulation thereafter, and/or if Seller receives any
unsolicited offers for the purchase of the Property, provided such offers are
not accepted, even on a back-up basis.

                           4.5.2    Until the Closing has occurred, Seller shall
keep in confidence and shall not disclose or permit or suffer the disclosure of
any information relating to this transaction, the identity of Buyer and the
terms and conditions of this Agreement to any person, firm or entity, except
that such information may be disclosed (i) to the Seller's partners, directors,
officers, existing and financing sources, assignees, lawyers, consultants, and
representatives as needed to enable Seller to complete its obligations or
exercise its rights hereunder, or (ii) to Seller's Agents.

                           4.5.3    Commencing on the Effective Date, subject to
Buyer's rights under Section 4.4, above, Seller shall continue to actively seek
tenants for Building 5.

                           4.5.4    The Bridge Lease governs that portion of a
pedestrian bridge (the "Bridge") which spans the San Tomas Aquinas Creek
adjacent to the Property, which Bridge also extends over the Eastern border of
and onto a portion of the Property. If the Santa Clara Valley Water District or
any other governmental agency requires removal of the Bridge across the San
Tomas Aquinas Creek, then Seller shall remove, at its sole cost and expense,
that portion of the Bridge which is on Santa Clara Valley Water District
property and subject to the Bridge Lease;

                                       8
<PAGE>

provided, however, that Seller's obligation shall not include any repair work
for that portion of the Bridge remaining on the Property (including without
limitation repair, shoring or reinforcement, installation of railings, and/or
removal of those portions of the Bridge located on the Property), the
performance and expense for which shall be Buyer's responsibility. Buyer agrees
to reasonably cooperate with Seller's performance of its obligations under this
Paragraph 4.5.4, including Seller's right to access over and onto the Property
to perform such work. Seller's obligations under this Section 4.5.4 shall
survive the Closing.

         5.       Title Review and Feasibility Period.

                  5.1      Title Report and Survey. Promptly after the execution
and delivery of this Agreement, Seller shall provide Buyer with (a) a current
title report for the Real Property, (the "Title Report") prepared by First
America Title Guaranty Company (the "Title Company"), (b) copies of documents
referenced in the exceptions set forth in the Title Report, and (c) the Survey.
Promptly after the Effective Date, Seller shall instruct the Title Company to
deliver the Title Report, copies of the documents referenced in the exceptions
thereto, and shall deliver the Survey to Buyer, Buyer's attorney (as identified
in Section 14 below), and Seller. In addition to any and all exceptions approved
by Seller pursuant to Section 5.1.1 below, the Title Report shall be subject to
and Buyer hereby approves as "Permitted Exceptions" the following: (i)
exceptions for general taxes not yet due and payable, and (ii) matters affecting
title attributable to the acts of Buyer and its agents, contractors and
employees.

                           5.1.1    Buyer shall have thirty (30) days after
receipt of the Title Report (such period herein called the "Title Objection
Period") to notify Seller and the Title Company in writing of Buyer's approval
or disapproval of any exceptions or other matters shown therein other than the
Permitted Exceptions listed in Section 5.1, above ("Notice of Title Objection")
and to request any endorsements to the Title Report that Buyer desires. If Buyer
does not give Seller written notice of disapproval of any such matters or
exceptions within the prescribed time, the Title Report, the Survey and the
supporting documents shall be deemed approved (and all exceptions therein shall
be deemed "Permitted Exceptions") and this condition shall be deemed satisfied.
Within seven (7) days after receipt of Buyer's notice of disapproval of any such
matters or exceptions timely delivered to Seller, Seller shall notify Buyer in
writing whether Seller is willing to remove any such item which Buyer has
disapproved ("Seller's Cure Item"). If Seller does not give Buyer written notice
within the prescribed period of time, Seller shall be deemed to have elected not
to remove any such item which Buyer has disapproved and such items shall not be
deemed Seller's Cure Items. If there are exceptions which Buyer has disapproved
and which Seller is not willing to remove at Seller's expense, Buyer shall have
until the end of the Feasibility Period to notify Seller in writing of Buyer's
election to either (i) waive its disapproval and approve such exceptions, or
(ii) terminate this Agreement and receive a return of the Deposit in accordance
with Section 2.1. If Buyer does not expressly elect to waive its disapproval in
a timely manner, then this Agreement shall terminate and the Deposit shall be
returned to Buyer.

                           5.1.2    Survey. Seller's sole obligation with
respect to a survey of the Property shall be to deliver the Survey to Buyer as
provided herein. Buyer shall be responsible, at its sole cost, for obtaining any
updates to the Survey and/or any new survey(s) of the Property.

                           5.1.3    Pre-Closing "Gap" Title Defects. Buyer may,
at or prior to Closing, deliver written notice to Seller (the "Gap Notice") of
any exceptions to title (a) raised by the Title Company between the expiration
of the Feasibility Period and the Closing and (b) not disclosed by the Title
Company or otherwise known to Buyer prior to the expiration of the Feasibility
Period; provided that Buyer must notify Seller of such objection to title within
two (2) Working Days of being made aware of the existence of such exception. If
Buyer sends a Gap Notice to Seller, Buyer and Seller shall have the same rights
and obligations with respect to such notice as apply to a Notice of Title
Objection under Section 5.1.1 above.

         5.2      Feasibility Period.

                  5.2.1    For the period commencing on the Effective Date and
expiring on the date which is sixty (60) days after the Effective Date, but in
no event later than October 15, 2003 (the "Feasibility Period"), Buyer and
Buyer's Agents shall have the right to enter the Real Property and to conduct
and carry out any and all inspections, tests and studies that Buyer deems
appropriate in its evaluation of the physical condition of the Property, the
compliance of the Property with applicable laws, and the suitability of the
Property for Buyer's intended use, as Buyer deems appropriate in its sole
discretion. Buyer shall be allowed until 5:00 P.M. (Pacific Time) on the last
day of the Feasibility Period to deliver to Seller, with a copy also to be
delivered to Escrow Agent and to Seller's counsel designated in Section 14
hereof, a written notice of Buyer's election to purchase the Property ("Buyer's
Notice"). Buyer's failure to deliver the Buyer's Notice within the Feasibility
Period shall conclusively be deemed Buyer's election not to purchase the
Property and to terminate the Agreement.

                  5.2.2    During the Feasibility Period, Buyer and Buyer's
Agents shall be granted a right of entry on the Real Property to perform such
soil, engineering and geological tests and other physical inspections, including
building systems and components, to make such other reports as Buyer shall deem
appropriate and for any other purpose related to Buyer's proposed use of the
Property. Buyer's entry onto the Real Property as provided in this Section 5.2
is referred to herein as the "Inspection." Buyer's right of entry upon the Real
Property for the purposes of the Inspection shall be subject to, and Buyer
agrees to perform, each of the following conditions and covenants, all of which
shall survive the termination of this Agreement or delivery of the Deed (as
hereinafter defined) and the Closing:

                           (i)      Buyer shall pay all costs, expenses,
liabilities and charges incurred by Buyer related to Buyer's entry.

                           (ii)     Buyer, at Buyer's sole cost, shall repair
all damage or injury caused by Buyer or Buyer's Agents in connection with any
such inspection or entry and shall return the Real Property to the condition
existing prior to such entry, it being understood, however, that Buyer shall not
be responsible for damage due to the mere discovery of a pre-

                                       10
<PAGE>

existing condition, provided Buyer shall be responsible for any exacerbation of
a pre-existing condition resulting from Buyer's activities.

                           (iii)    Any such entry upon the Real Property shall
be upon no less than 24 hours advance notice to Seller and shall be at
reasonable times during normal business hours and shall not unreasonably
interfere with the Seller's and/or Magma's operations on the Real Property.
Seller shall have the right to accompany Buyer and Buyer's Agents during any
entry upon the Real Property and to require that Buyer and Buyer's Agents comply
with Seller's reasonable security procedures.

                           (iv)     Buyer shall keep the Real Property free and
clear of all liens arising out of Buyer's activities conducted upon the Real
Property.

                           (v)      Buyer shall indemnify and hold Seller
harmless from any lien, loss, claim, liability, or expense, including reasonable
attorneys' fees and costs, directly arising out of or in connection with the
Inspection. Such obligation to indemnify and hold Seller harmless shall survive
Closing or any termination of this Agreement.

                           (vi)     Buyer shall provide (or cause Buyer's Agents
to provide) liability insurance with a combined single limit liability of not
less than Five Million Dollars ($5,000,000), either under Buyer's policy or such
insurance provided by Buyer's Agents, and which liability insurance shall cover
all activities performed by Buyer or Buyer's Agents, in connection with the
Inspection activities. Seller shall be named as an additional insured upon such
insurance. Buyer shall provide proof of such insurance in the form of a
certificate of insurance prior to, and as a condition of, any such entry.

                           (vii)    Buyer shall not conduct any invasive testing
of the Real Property without Seller's prior written approval, which shall
include a work plan acceptable to Seller. Prior to performing any environmental
tests or studies on the Real Property beyond the scope of work generally
performed in a "Phase I" environmental property assessment study, Buyer shall
notify Seller of the scope of work intended to be performed and shall provide
Seller an opportunity to confer, either directly or through Seller's
consultants, with Buyer's environmental consultants in order to determine
whether to consent to any sampling or testing of surface or subsurface soils,
surface water or ground water. Seller shall not unreasonably withhold consent to
any inspections of the existing Improvements (including asbestos testing)
requested to be performed by Buyer. Seller may elect to deny Buyer permission to
conduct invasive testing or other inspections of the soils, surface water or
ground water based on Seller's good faith determination, in its sole discretion,
that such inspections are inadvisable, including without limitation for any of
the following reasons: (A) Seller's environmental consultants object to the
methodology or procedures of the inspections proposed, (B) or such inspections
otherwise do not satisfy the requirements set forth in this Section 5. In any
event, if Seller has not consented or refused to consent in writing to such
environmental tests or studies within three (3) Working Days of Buyer's written
notification to Seller requesting such consent, Seller shall be deemed to have
refused to consent to such tests and/or studies. Prior to the Closing, all
information derived from Buyer's tests and test results shall, to the extent
permissible under

                                       11
<PAGE>

existing law, remain confidential and shall not be disclosed to any party other
than as is necessary to consummate the transaction contemplated hereby or to
exercise Buyer's rights hereunder including, without limitation, to Buyer's
counsel and its consultants, and to Buyer's prospective lenders and partners, if
any, or as required to comply with any applicable Laws. At Seller's request,
Buyer shall provide Seller with copies of all reports and test results relating
to Buyer's tests and evaluations of the environmental or physical condition of
the Real Property prior to the Closing. Buyer shall obtain all consultants'
consent to the foregoing as a part of any retention agreement with the
consultant. Seller's rights to such reports and test results relating to the
environmental or physical conditions of the Real Property shall survive the
Closing and recording of the Deed from Seller to Buyer. Buyer shall bear the
costs and expenses with respect to its feasibility studies hereunder, including,
but not limited to, all environmental matters and investigations.

         6.       Buyer's Covenants, Representations, Warranties and
Acknowledgments. Buyer hereby represents and warrants to Seller and covenants
with Seller as follows:

                  6.1      Authority. Subject to Section 7.1.6, below, Buyer has
the power and authority to enter into and to perform all of Buyer's obligations
pursuant to this Agreement, and to purchase the Property on the terms and
conditions set forth herein. No consent of any third party is required in order
for Buyer to perform any of its obligations hereunder. Buyer will finance the
purchase of the Property using Buyer's own funds, and no third party financing
shall be required in order for Buyer to consummate its purchase of the Property.

                  6.2      No conflict. This Agreement and Buyer's purchase of
the Property hereunder do not violate any material terms or provisions of any
contract to which Buyer is a party.

                  6.3      Confidentiality and Exclusivity.

                           6.3.1    Definitions. As used herein, the following
terms have the meanings set forth below: (i) the term "Information" shall mean
all information relating to the products, business, assets, financial condition
or prospects of 3Com which has been or may hereafter be furnished to Buyer; and
(ii) the term "Confidential Information" shall mean all Information which 3Com
protects against unrestricted disclosure to others and which: (i) if in written
or other tangible form, is clearly designated as "Confidential" or
"Proprietary"; and (ii) if disclosed orally, is identified as confidential at
the time of its disclosure and reduced to a writing designating such Information
as "Confidential" which is delivered to Buyer promptly following such oral
disclosure. By way of illustration, but not limitation, Confidential Information
may include designs, structures, processes, financial information and data
regarding suppliers and customers.

                           6.3.2    Non-Disclosure. Until the Closing, Buyer
agrees, with respect to any Confidential Information received by it from 3Com:
(i) to hold the Confidential Information in confidence and use it only for the
purposes previously stated (i.e. for the purpose of evaluating and effecting the
proposed purchase and sale transaction between the parties hereto); (ii) to use
the same methods and degree of care to prevent disclosure of the Confidential
Information as it uses to prevent disclosure of its own proprietary and
confidential information; (iii) not to disclose

                                       12
<PAGE>

any Confidential Information to any third party (other than directors and
officers of Buyer, employees of Buyer involved directly with the proposed
transaction and counsel and financial advisors to Buyer, all of whom shall be
informed of the confidential nature of the Confidential Information), without
the prior written consent of 3Com; and (iv) if this Agreement is terminated for
any reason, to promptly return the Confidential Information received in any
tangible form to 3Com at the request of 3Com and to retain no reproductions,
copies, extracts or summaries of any Confidential Information.

                           6.3.3    Exclusivity. Commencing on the Effective
Date and through the date this Agreement is terminated or the parties proceed to
Closing, Buyer agrees that it shall not review, tour, offer to purchase or
otherwise conduct negotiations or discussions with any party for the possible
lease or purchase of real property in Santa Clara, San Mateo and/or Alameda
Counties other than the Property which is comparable to the Property.

                  6.4      Limitations. Buyer shall not be obligated to treat
Information as Confidential Information if such Information: (i) was rightfully
in Buyer's possession or was rightfully known to Buyer prior to receipt from
3Com; (ii) is independently developed by Buyer, provided that the burden of
proof of such independent development shall be on Buyer; (iii) is or becomes
publicly known WITHOUT the fault of Buyer; (iv) is or becomes rightfully
available to Buyer without confidential restriction from a source not bound by a
confidentiality obligation to 3Com; or (v) is required to be disclosed pursuant
to court or government action provided, however, that 3Com is given reasonable
prior notice of such disclosure. The obligations of confidentiality and other
restrictions imposed under this Agreement shall terminate with respect to each
item of Confidential Information one (1) year from the date of its delivery to
Buyer.

                  6.5      "AS IS" Purchase. Seller shall deliver the Property
at the Closing with the interior of the Buildings in its "AS IS" condition.
Except for and subject to the representations and warranties of Seller as are

if any, (a) Buyer acknowledges and agrees that Buyer is acquiring the Property
in its "AS IS" condition, WITH ALL FAULTS, IF ANY, AND WITHOUT ANY WARRANTY,
EXPRESS OR IMPLIED, and (b) neither Seller nor any agents, representatives, or

square footage of the Land or the Improvements thereon, the condition of the
Property, its fitness for any particular purpose, or its compliance with any
laws, Seller expressly disclaims any such representations or warranties and

of any other party. Buyer acknowledges that the Feasibility Period will have
afforded Buyer an adequate period of time and the opportunity to make such
inspections (or have such inspections made by consultants) as it desires of the
Property and all factors relevant to its use, and that Buyer has elected to go
forward with the purchase of the Property based on such examinations and
inspections as Buyer has deemed appropriate to make. Buyer agrees that, except
as specifically provided in Section 3.1 of this Agreement, Seller has not made,
does not make and specifically disclaims any representations, warranties,
covenants, agreements or guaranties of any kind or character whatsoever, whether
express or implied, oral or written, past, present or future, concerning the

                                       13

Section 6.5(b), below), land use laws and the Americans with Disabilities Act of
1990; (g) the presence or absence of hazardous materials at, on, under or

         BUYER ACKNOWLEDGES AND AGREES THAT ANY INFORMATION MADE AVAILABLE TO
BUYER OR PROVIDED OR TO BE PROVIDED BY OR ON BEHALF OF SELLER WITH RESPECT TO
THE PROPERTY WAS OBTAINED FROM A VARIETY OF SOURCES AND THAT NEITHER SELLER NOR
ITS AGENTS HAVE MADE ANY INDEPENDENT INVESTIGATION OR VERIFICATION OF SUCH
INFORMATION AND MAKES NO REPRESENTATIONS AS TO THE ACCURACY OR COMPLETENESS OF
SUCH INFORMATION EXCEPT AS MAY OTHERWISE BE EXPRESSLY PROVIDED HEREIN. BUYER
FURTHER ACKNOWLEDGES AND AGREES THAT TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE
SALE OF THE PROPERTY AS PROVIDED FOR HEREIN IS MADE ON AN "AS-IS" CONDITION AND
BASIS, WITH ALL FAULTS.

         The provisions of this Section 6.4 shall survive the Closing and the
delivery of the Deed.

                  6.6      Release of Claims.

                           (a)      From and after the Closing, Buyer hereby
completely releases and forever discharges and covenants not to sue Seller and
Seller's affiliates, employees, successors, assigns, heirs, agents, and
representatives from and against all claims, liabilities, demands, orders,

storage, transportation or disposal of Hazardous Materials at or from the Real

other latent or patent defect affecting the Real Property (collectively, the
"Released Matters"); provided, however, that subject to the limitations on
Buyer's remedies set forth in Section 11.2 hereof the

                                       14
<PAGE>

Released Matters shall not include (x) Claims arising from Hazardous Materials
placed at on the Real Property by Seller during the period during which Seller
held title to the Property, or (y) Claims arising from any breach of an express
representation or warranty by Seller under Section 3.1 hereof. In connection
with such waiver and relinquishment, Buyer acknowledges that it is aware that it
hereafter may discover Claims or facts in addition to or different from those
which it now knows or believes to exist with respect to the Released Matters,
but that it is its intention to fully, finally and forever to settle and release
all of the Released Matters in accordance with the provisions of this Section
6.5, and the release set forth herein shall be and remain in effect as a full

and asbestos containing materials ("ACM")). As used herein, the term
"Environmental Laws" means any applicable federal, state, local or foreign law
(including common law), statute, regulation, rule, ordinance, permit, license,

directive or order of any executive or judicial authority at any federal, state
or local level (whether now existing or subsequently adopted or promulgated)
relating to pollution or the protection of the environment, natural resources,
flora, fauna, or public or worker health and safety.

                  6.7      No Title Warranty. Nothing in this Agreement or in
any instrument delivered by Seller to Buyer shall be construed as a warranty or
representation by Seller, either express or implied, concerning Seller's title
to the Property, and Owner makes no such warranty or representation. Buyer is
relying solely upon the Title Report, the Title Policy and Buyer's own
investigations respecting Seller's title to the Property.

believes that any condition to Closing has not been satisfied, then Buyer
immediately shall notify Seller thereof. Buyer acknowledges that certain
conditions precedent set forth in Section 7.1 hereof may not be under Seller's
control, and the mere failure of a condition precedent to be satisfied shall not
by itself be deemed to constitute a default by Seller hereunder. In the event

satisfied or, at Seller's option, to terminate this Agreement, and each party

party as provided in and limited by Section 11 of this Agreement. If Seller
believes that any condition to Closing has not been satisfied, then Seller
immediately shall notify Buyer thereof. Seller acknowledges that certain
conditions precedent set forth in Section 7.2 hereof may not be under Buyer's
control, and the mere failure of a condition precedent to be satisfied shall not
by itself be deemed to constitute a default by Buyer hereunder. In the event
this Agreement is terminated due to the failure of any of Seller's conditions
precedent, all obligations, liabilities and rights of the parties hereunder
shall terminate excepting any obligations which expressly survive the Closing or
termination hereof, and Buyer

                                       17

shall promptly return to Seller all documentation delivered by Seller to Buyer
and shall provide copies to Seller of all reports and studies obtained or
developed by Buyer with respect to the Property, at no cost to Seller.

         8.       Closing; Deliveries.

                  8.1      Timing of Closing. The consummation of the

Company (or on such earlier date and time, at such other location, as shall be
mutually agreed to by Seller and Buyer). At the Closing, Seller and Buyer shall
have made the Closing deliveries set forth in, respectively, Sections 8.2, 8.3

Seller at least three (3) Working Days advance notice.

the form of EXHIBIT "F" hereto.

         9.       Apportionments; Taxes; Expenses.

                  9.1      Apportionments and Prorations. At the Closing the
following items and any other items customarily prorated in similar transactions
shall be adjusted and apportioned by credits to the appropriate party on the
Closing Statement as of the end of the day (the "Adjustment Date") immediately
prior to the date of Closing (unless otherwise specified below), it being hereby
acknowledged and agreed, that all items of income and expense for the period
prior to the end of the Adjustment Date shall be for the account of Seller and
all items of income and expense for the period following the Adjustment Date
shall be for the account of Buyer:

                                       19
<PAGE>

                           9.1.1    Taxes and Other Expenses. The parties agree
that as between Buyer and Seller, general real estate taxes, personal property
taxes and ad valorem taxes (collectively, "Taxes"), as well as utility,
maintenance and other operating expenses (collectively with taxes, "Property
Expenses") for periods prior to the Closing shall be Seller's sole
responsibility, and Property Expenses for the period from and after the Closing
shall be Buyer's sole responsibility, subject to the following provisions of
this Section 9.1.1. If and to the extent that the final amounts of any Property
Expenses are unavailable at the Closing (including, but not limited to, utility
charges for which final meter readings cannot be made), Seller and Buyer shall
adjust the same based upon a reasonable estimate of that item and a readjustment
thereof as of the Adjustment Date will be made as soon as the final amounts are
ascertainable, with the party owing sums following such post-closing adjustments
paying same to the other within ten days following such readjustment; provided,
however, that with respect to all Property Expenses other than Taxes, the
parties agree to reconcile such amounts within ninety (90) days after the
Closing, and provided further, that the parties shall make no such post-closing
adjustment if the aggregate amount of such adjustments is less than $500.
Notwithstanding the foregoing, nothing herein shall be deemed to assign to Buyer
any right of Seller to appeal or apply for a reduction in Taxes for periods
attributable prior to the Closing, and Seller shall be entitled to pursue any
and all such appeals after the Closing at its expense, and Buyer expressly
disclaims any interest whatsoever in any tax reductions or credits obtained by
Seller in connection therewith. In the event any such appeal or application by
either party results in a refund to Buyer of Taxes attributable to the period
before Closing, then Buyer shall pay such amounts to Seller promptly after
receipt, reduced by a percentage of Buyer's expenses in connection with such
appeal or application equal to the percentage Seller's portion of such refund
bears to the entire Tax refund paid to Buyer. In the event any such appeal or
application by either party results in a refund to Seller of Taxes attributable
to the period after Closing, then Seller shall pay such amounts to Buyer
promptly after receipt, reduced by a percentage of Seller's expenses in
connection with such appeal or application equal to the percentage Buyer's
portion of such refund bears to the entire Tax refund paid to Seller.

                           9.1.2    Assigned Contracts. To the extent there are
any unpaid monetary obligations of Seller with respect to any of the Assigned
Contracts as of the Closing Date, such obligations shall be included within the
Property Expenses and apportioned between Buyer and Seller as provided in
Section 9.1.1, above.

                           9.1.3    Rent. Rent under the Magma Lease shall be
apportioned as of the Closing, to the extent such rent has actually been
collected as of such date. Seller agrees to credit Buyer at Closing for one (1)
month's Base Rent previously collected by Seller and applicable to the first
calendar month of the lease term occurring after the "Free Rent Period", as
defined in the Magma Lease, so long as the Closing occurs prior to such Free
Rent Period. Notwithstanding the foregoing, all other components of "Rent" under
the Magma Lease shall be apportioned as of the Closing. If Seller collects or
receives any rent payments which properly belong to Buyer, Seller shall
immediately pay such amounts to Buyer. If Buyer collects or receives any rent
payments which properly belong to Seller, Buyer shall immediately pay such
amounts to Seller.

                                       20
<PAGE>

                           9.1.4    Security Deposits. Buyer and Seller agree
and acknowledge that the only security deposit held for a Lease on the Property
is a $100,000 deposit under the Magma Lease, held by Seller in the form of a
letter of credit (the "LC"). Seller shall deliver the original LC to Buyer
through Escrow at Closing, and shall cooperate with Buyer and shall make
commercially reasonable efforts to cause the transfer to Buyer of the
beneficiary's rights under the LC, provided that if Seller fails to achieve the
transfer of such letters of credit, Seller shall not be in default hereunder,
and in no event shall such failure delay or prevent the Closing. Seller's
obligations under this Section 9.1.4 shall survive the Closing.

                           9.1.5    Other Tenant Charges. Notwithstanding
Section 9.1.1 and Section 9.1.2 above, any amounts payable by the Tenants under
the Magma Lease for taxes, common area expenses, operating expenses, or
additional charges of any other nature relating to the Property, if any, shall
be prorated as of the Closing ("Expense Reimbursements"), with Seller retaining
rights to Expense Reimbursements relating to periods before the Closing and
Buyer being entitled to Expense Reimbursements relating to periods after the
Closing. If the Expense Reimbursements are required to be reconciled by the
landlord at the end of the calendar year or other specified time period, Buyer
shall perform such reconciliation as and when required and shall deliver a copy
thereof to Seller. In such event, Seller shall reimburse Buyer, or Buyer shall
reimburse Seller, as appropriate, for any amounts that such party is responsible
to pay or is entitled to receive as the result of underpayments or overpayments
of Expense Reimbursements.

                           9.1.6    Lease Commissions and Allowances. Seller
shall remain liable for the obligation to pay for all leasing commissions
payable in connection with the Magma Lease (and any other leases entered into by
Seller pursuant to the terms of this Agreement) pursuant to the terms of such
lease and any commission agreements binding on Seller with respect thereto;
provided, however, that Seller shall not be liable to Buyer, nor shall Buyer
receive a credit at Closing, for any free rent period under the Magma Lease (or
any other leases entered into by Seller pursuant to the terms of this Agreement)
to the extent such period occurs after the Closing.

                  9.2      Expenses. The expenses and costs of the transactions
contemplated by this Agreement shall be borne by the parties as follows, all of
which obligations shall survive the Closing:

                           9.2.1    Advisors. Except as otherwise provided in
this Agreement, each party will pay all its own expenses incurred in connection
with this Agreement and the transactions contemplated hereby, including, without
limitation, (a) all costs and expenses stated herein to be borne by such party,
and (b) all of its own respective accounting, legal and appraisal fees.

                           9.2.2    Seller's Expenses. Provided the Closing
occurs, Seller shall pay at the Closing (a) the cost of a standard CLTA Title
Policy, and (b) One Hundred percent (100%) of all State of California and County
of Santa Clara real estate transfer taxes.

                           9.2.3    Buyer's Expenses. Buyer shall pay all costs,
expenses and fees incurred in connection with its "due diligence" activities.
Provided the Closing occurs, Buyer

                                       21
<PAGE>

shall pay at the Closing all premiums associated with any ALTA extended coverage
for the owner's Title Policy, together with the cost of all endorsements
requested by Buyer.

                           9.2.4    Escrow and Other Expenses. The cost of all
escrow and recording fees shall be shared equally by Buyer and Seller. All other
customary and usual closing costs, if any, shall be borne by the parties in
accordance with the custom of Santa Clara County, as determined by the Title
Company.

                  9.3      Survival. The obligations of the parties pursuant to
this Section 9 shall survive the Closing and shall not merge into any documents
of conveyance delivered at Closing.

         10.      Casualty; Condemnation; Insurance.

                  10.1     Threshold Amount for Termination Option. If, at any
time prior to the date of Closing, Improvements having a replacement value of
$500,000 or more are destroyed or damaged as a result of fire or any other
casualty whatsoever, or as a result of the fact that any portion of the Real
Property is condemned by eminent domain proceedings by any public authority,
then, at Buyer's option, this Agreement shall terminate, and the Deposit shall
be returned to Buyer, and except as expressly set forth herein, neither party
shall have any further liability or obligation to the other hereunder. Buyer
shall exercise such termination right, if at all, within fifteen (15) days after
receipt of written notice from Seller advising Buyer of such casualty or
condemnation.

                  10.2     Allocation of Compensation. If there is any casualty
or taking as above set forth and if (a) the casualty or condemnation involves
less than $500,000, or (b) Buyer elects not to terminate this Agreement as
provided above, then (1) in the case of condemnation, all eminent domain
proceeds paid or payable to Seller shall belong to Buyer and shall be paid over
and assigned to Buyer at Closing; and (2) in the case of a casualty, Seller
shall assign to Buyer all rights to any insurance proceeds paid or payable under
the applicable insurance policy(ies) and Buyer shall receive a credit at Closing
in the amount of the applicable deductible or co-payment. In no event shall
Seller have any obligation to restore any damage to or loss of the Real Property
caused by or arising from casualty or condemnation, nor shall Buyer have the
right to terminate this Agreement in such a case except as set forth in Section
10.1 hereof.

         11.      Remedies for Buyer's Default and Seller's Default.

                  11.1     BUYER'S DEFAULT. FROM AND AFTER THE EXPIRATION OF THE
FEASIBILITY PERIOD, IN THE EVENT THE SALE OF THE PROPERTY AS CONTEMPLATED
HEREUNDER IS NOT CONSUMMATED DUE TO A DEFAULT OF THIS AGREEMENT BY BUYER, THEN
SELLER SHALL, AS ITS SOLE AND EXCLUSIVE REMEDY THEREFOR, HAVE THE RIGHT TO
TERMINATE THIS AGREEMENT, IN WHICH CASE IT SHALL BE ENTITLED TO RECEIVE THE
DEPOSIT, INCLUDING ALL ACCRUED INTEREST THEREON, AS LIQUIDATED DAMAGES (AND NOT
AS A PENALTY) IN LIEU OF, AND AS FULL COMPENSATION FOR, ALL OTHER RIGHTS OR
CLAIMS OF SELLER AGAINST BUYER BY REASON OF SUCH DEFAULT. UPON SUCH DEFAULT BY
BUYER, THIS AGREEMENT SHALL TERMINATE AND THE PARTIES

                                       22
<PAGE>

SHALL BE RELIEVED OF ALL FURTHER OBLIGATIONS AND LIABILITIES HEREUNDER, EXCEPT
AS EXPRESSLY SET FORTH HEREIN. BUYER AND SELLER ACKNOWLEDGE THAT THE DAMAGES TO
SELLER RESULTING FROM BUYER'S BREACH WOULD BE DIFFICULT, IF NOT IMPOSSIBLE TO
ASCERTAIN WITH ANY ACCURACY, AND THAT THE LIQUIDATED DAMAGE AMOUNT SET FORTH IN
THIS SECTION 11.1 REPRESENTS BOTH PARTIES' EFFORTS TO APPROXIMATE SUCH POTENTIAL
DAMAGES AND IS REASONABLE UNDER THE CIRCUMSTANCES EXISTING ON THE EFFECTIVE
DATE. NOTHING HEREIN SHALL LIMIT SELLER'S REMEDIES WITH RESPECT TO ANY BREACH OF
ANY COVENANT OF BUYER TO INDEMNIFY, DEFEND, PROTECT OR HOLD HARMLESS SELLER OR
TO REIMBURSE SELLER FOR ANY SUMS OTHERWISE PAYABLE TO SELLER (INCLUDING
ATTORNEYS' FEES AND COSTS), OR TO PROVIDE CERTAIN DOCUMENTS TO SELLER AFTER
TERMINATION AS PROVIDED HEREIN, TO THE EXTENT SUCH COVENANT SURVIVES THE
TERMINATION OF THIS AGREEMENT OR THE CLOSING UNDER THE EXPRESS TERMS OF THIS
AGREEMENT. BUYER AND SELLER SPECIFICALLY ACKNOWLEDGE THEIR AGREEMENT TO THE
FOREGOING LIQUIDATED DAMAGES PROVISION BY INITIALING THIS PARAGRAPH IN THE
APPROPRIATE SPACES PROVIDED BELOW:

Buyer's Initials ________                   Seller's Initials ___________

                  11.2     Seller's Default. In the event that the Closing does
not occur as a result of a breach of any of Seller's covenants, representations,
warranties or other obligations under this Agreement, and if such breach is not
cured within five (5) days after Seller's receipt of written notice specifying
such breach, then Buyer shall have as its sole and exclusive remedy the right to
either (a) terminate this Agreement and to receive a return of the Deposit and
(if Buyer so elects) to file an action for Buyer's actual damages to recover
Buyer's out-of-pocket costs incurred in connection with the transactions
contemplated by this Agreement (but in no event any punitive, consequential, or
special damages) in an amount not to exceed $1,000,000, or (b) seek the remedy
of specific performance to enforce Seller's obligation to convey title to the
Property to Buyer in accordance with the terms and conditions of this Agreement,
it being understood and agreed, however, that the remedy of specific performance
shall not be available to enforce any other obligation of Seller hereunder.
Buyer hereby waives any right or remedy available at law or in equity to seek
damages in excess of $1,000,000 in the event of Seller's breach of any covenant,
representation, warranty or other obligation hereunder. Buyer shall be deemed to
have elected to seek the remedy referred to in clause (a) of this Section 11.2
unless Buyer files suit for specific performance within 30 days after the later
of (i) the scheduled Closing Date, or (ii) the date Seller's cure period has
expired.

         12.      Further Assurances. Seller and Buyer each agrees to perform
such other acts, and to execute, acknowledge and deliver, prior to, at or
subsequent to the Closing, such other customary instruments, documents and other
materials as the other may reasonably request and as shall be necessary in order
to effect the consummation of the transactions contemplated hereby.

                                       23
<PAGE>

         13.      Possession. Subject to the Magma Lease, possession of the
Property shall be surrendered by Seller to Buyer at Closing. Notwithstanding the
preceding sentence, Buyer acknowledges that Seller shall have a right of access,
for one hundred twenty (120) days after Closing (the "Transition Period"), in
and to the following portions of the Property: (i) PBX room in Building 4, (ii)
network room located in Building 3, both of which are shown on EXHIBIT "G",
attached hereto, and (iii) all telecommunication lines and conduit located in
Building 3 and running from Building 3 to the Property line (collectively the
"Transition Facilities"). Buyer agrees that, during the Transition Period, it
shall make commercially reasonable efforts to provide continuous utilities and
services to the Transition Facilities in connection with Seller's transition of
its operations out of the Improvements, including without limitation
electricity, 24 hour HVAC (for the indoor Transition Facilities), backup
generator and UPS service (collectively, "Services"), at no cost to Seller.
Seller agrees that during the Transition Period, its right to use and access the
Transition Facilities shall be subject to the following conditions:

                  13.1     Buyer shall not be liable to Seller for any loss,
injury or other damage to Seller arising from or in connection with any
interruption or termination of the Services from any cause, and Seller hereby
waives all such claims against Buyer except to the extent caused by Buyer's
gross negligence or willful misconduct. Notwithstanding any other provision of
this Agreement to the contrary, in no event shall Buyer be liable to Seller for
any indirect, punitive or consequential damages in connection with Seller's use
of the Transition Facilities.

                  13.2     Seller shall make commercially reasonable efforts not
to interfere with the operations of Buyer or any other tenant or occupant of the
Property in connection with Seller's use of the Transition Facilities.

                  13.3     During the Transition Period, Seller shall continue
to maintain its liability and property insurance covering the Transition
Facilities in the same form as such facilities have been insured prior to the
Closing. Buyer and Seller agree that their respective property loss risks shall
be borne by their own insurance carriers, and agree to look solely to, and seek
recovery only from, their respective insurance carriers in the event of a
property loss to the extent that such coverage is carried by such party. The
parties each hereby waive all rights and claims against each other for such
losses to the extent of such insurance, and waive all rights of subrogation of
their respective insurers. The parties agree that their respective insurance
policies are now, or shall be, endorsed such that the waiver of subrogation
shall not affect the right of the insured to recover thereunder.

         The terms and conditions of this Article 13 shall survive the Closing.

         14.      Notices. All notices and other communications provided for
herein shall be in writing and shall be sent to the address set forth below (or
such other address as a party may hereafter designate for itself by notice to
the other parties as required hereby) of the party for whom such notice or

         15.      Brokers. Pursuant to a separate agreement between Seller and

connection with the purchase and sale of the Property or any other matter
contemplated by this Agreement other than CPS, A Commercial Real Estate Company,
Inc. ("Buyer's Broker"). Seller agrees to pay Seller's Broker pursuant to its
existing agreement, and Seller shall also pay a commission to Buyer's Broker
pursuant to a separate agreement between Seller and Buyer's Broker. Nothing in
this Agreement shall modify Seller's agreement with Seller's Broker or create
any dual agency by Buyer's Broker. Except as referred to in the preceding
provisions of this Section 15, Buyer and Seller each represents to the other
that it has not dealt with any broker or agent in connection with this
transaction. Each party hereby indemnifies and holds harmless the other party
from all loss, cost and expense (including reasonable attorneys' fees) arising
out of a breach of its representation or undertaking set forth in this Section
15. The provisions of this Section 15 shall survive the Closing or the
termination of this Agreement.

deliveries as contemplated by Section 8 of this Agreement and conduct the
Closing in accordance with the terms and provisions of the escrow instructions
to be provided to the Escrow Agent by the parties hereto prior to Closing.

the Closing, Buyer shall permit Seller's employees (up to a maximum of 125
employees at any given time) the continued right to use the Fitness Center
located at the Real Property; provided, however, that such rights shall be
personal to 3Com, and shall only be available to 3Com employees working in Santa
Clara County. Such use by Seller's employees shall be permitted subject to
payment of a monthly membership charge not to exceed Thirty Dollars ($30.00) per
month and execution of any reasonable waiver form requested by Buyer or its
agents. Buyer also reserves the right to (i) restrict the hours of usage for
Seller's employees, so long as such use is available from 6 a.m. to 9 p.m.,
Monday through Friday, (ii) to impose reasonable rules and regulations, so long
as the

                                       26
<PAGE>

same are consistently applied in a non-discriminatory manner, and (iii)
discontinue operating any Fitness Center altogether. The provisions of this
Section 17 shall survive the Closing and shall be binding on Seller, Buyer and
their respective successors and assigns.

         18.      California Disclosure Report/Wetlands Disclosure. Seller
acknowledges that the Disclosure Statutes (hereinafter defined) provide that a
seller of real property must make certain disclosures regarding certain natural
hazards potentially affecting the property, as more particularly provided
therein. As used in this Agreement, "Disclosure Statutes" means, collectively,
California Government Code Sections 8589.3, 8589.4 and 51183.5, California
Public Resources Code Sections 2621.9, 2694 and 4136 and any other California
statutes that require Seller to make disclosures concerning the Property. Prior
to the expiration of the Feasibility Period, Seller will deliver to Buyer a
Natural Hazard Disclosure Report for the Property in accordance with the
foregoing statutes (the "Report"). Buyer hereby agrees as follows with respect
to the Disclosure Statutes and the Report: (i) that the delivery of the Report
to Buyer as provided above shall be deemed to satisfy all obligations and
requirements of Seller under the Disclosure Statutes; (ii) that Seller shall not
be liable for any error or inaccuracy in, or omission from, the information in
the Report; (iii) that the Report was provided by Seller for purposes of
complying with the Disclosure Statutes and shall not be deemed to constitute a
representation or warranty by Seller as to the presence or absence in, at or
around the Property of the conditions that are the subject of the Disclosure
Statutes; and (iv) the Report is for Seller and Buyer only and is not for the
benefit of, or to be used for any purpose by, any other party, including,
without limitation, insurance companies, lenders, or governmental agencies. In
addition, Seller hereby discloses to Buyer that a portion of the Land has been
designated as a protected wetlands area. Buyer agrees that Seller has made no
representation or warranty with respect to such portions of the Property, and
agrees to satisfy itself during the Feasibility Period that the existence of a
designated wetlands area, together with jurisdiction over such areas by various
State and Federal governmental agencies, will not adversely affect Buyer's
intended use, development or disposition of the Property.

         19.      Miscellaneous.

                  19.1     Assignability. Buyer shall not assign its rights
under this Agreement without Seller's prior written consent. Any assignee of

Agreement, and any such assignment shall not release Buyer from any of its
obligations hereunder. Notwithstanding the foregoing, Buyer shall have the right
to assign all of its rights and obligations under this Agreement to any entity
wholly owned by Buyer, and to cause such entity to take title to the Property at
the Closing, upon written notice to Seller but without the requirement of
obtaining Seller's consent, and in such event, no such assignment shall operate
to release Buyer from any of its obligations under this Agreement.

                  19.2     Governing Law; Parties in Interest. This Agreement
