                                  CONTINGENCIES

5.1. EFFECT OF CONDITIONS GENERALLY. The Closings and the parties' obligations
with respect to each Property shall be contingent upon the satisfaction (or
deemed satisfaction as specifically set forth in each Section herein) or waiver
by TST or Symantec of all of the conditions that are expressly stated to be in
favor of each as set forth in this Article and the Conditions to Closing as set
forth in Schedule "3" hereof, within the time limits specified in each Section
of this Article and such Schedule.

   5.1.1. FAILURE OF CONDITIONS. In the event that any such condition is neither
   satisfied within the time limits specified in each such Section nor waived in
   writing by the Party specifically stated to be benefited by such Section,
   such condition shall be deemed to have failed and the Party specifically
   stated to be benefited by such failed condition, may elect to terminate this
   Agreement by notice to the other Party and to Escrow Holder given before such
   failed condition has been satisfied. In the event of any termination pursuant
   to this Article, TST and Symantec shall be released from their respective
   obligations to exchange, purchase or sell under this Agreement and shall have
   no further rights or remedies regarding exchange, purchase or sale against
   the other as a result of such termination, except for (a) the return to TST
   of TST's Deposit (if applicable) with interest actually earned thereon
   pursuant to Section 4.2.3.1 and the payment of 50% of any escrow cancellation
   fees, and (b) the return to Symantec of Symantec's Deposit (if applicable)

   Holder to evidence such termination.

   5.1.2. CONDITIONS ARE NOT COVENANTS. Conditions specified in this ARTICLE 5
   or in Schedule "3" as being for the benefit of TST or Symantec are NOT also
   to be considered as "covenants" of TST or Symantec unless such conditions are
   also listed 

                                       16
   17

   as either "TST's Covenants" or "Symantec's Covenants" in ARTICLE 5 or in 
   Schedule "3."

5.2. CONDITIONS APPLICABLE TO BOTH PARTIES. The following conditions shall be
for the benefit of each Party:

   5.2.1. FEASIBILITY STUDIES. This Agreement is contingent on each Party's
   approval of any and all investigations, studies or analyses for the Property
   deemed appropriate by a Party to aid such Party in determining whether to
   consummate the transaction ("Feasibility Studies"). Either Party may elect in
   such Party's sole and unreviewable discretion, at any time prior to the end
   of the Feasibility Period to terminate this Agreement.

   Upon such election to terminate, the Deposit together with interest earned
   thereon shall be returned to the Party making such Deposit.

   Without limiting the generality of the foregoing, each Party shall have the
   right to have prepared and to evaluate, both at the requesting Party's sole
   expense, during the Feasibility Period, including, but not limited to, the
   following:

      5.2.1.1. LEASES.  The Leases, if any, for each Property;

      5.2.1.2. SITE APPRAISAL.  An appraisal of the Property;

      5.2.1.3. SURVEY. An ALTA survey, and Symantec agrees that as soon as
      reasonably possible following the Agreement Date, Symantec shall obtain at
      Symantec's sole cost and expense, and deliver to TST an ALTA "As Built"
      survey showing the location on the CCC5 Property of Building CCC5;

      5.2.1.4. SITE IMPROVEMENTS. An inspection of any existing site
      improvements (including, without limitation, location and availability of
      utilities and a consultant's analysis of the buildings and other
      improvements on the Property);

      5.2.1.5. ENVIRONMENTAL, SOIL, AND GROUND WATER CONDITIONS. Environmental,
      soil and groundwater conditions concerning, without limitation, (i) the
      stability and load bearing capacity of the soil, and (ii) the presence of
      Hazardous Material on or under the Property or the potential for migration
      of Hazardous Material onto or under the Property from other property;
      provided, however, each Party agrees not to perform any drilling without
      giving the other Party notice at least two (2) business days in advance;

      5.2.1.6. ENTITLEMENTS AND APPROVALS. An analysis of governmental approvals
      and entitlements for the Projects;

      5.2.1.7. SERVICE CONTRACTS.  The Service Contracts, if any, for each 
      Property; and

      5.2.1.8. WITH RESPECT TO CCC2. Without limiting the generality of Section
      5.2.1, TST specifically acknowledges that, in addition to the general
      rights available to 


                                       17
   18

      both Symantec and TST to terminate this Agreement for any reason prior to 
      the end of the Feasibility Period, Symantec may decline to give its 
      Election to Proceed as to CCC2 unless both of the following have occurred 
      within the Feasibility Period:

         5.2.1.8.1 FINANCING. TST is aware that CCC5 and WHQ are owned by
         Sumitomo Bank Leasing and Finance, Inc. and leased to Symantec in an
         "off balance sheet" financing transaction known as a "Synthetic Lease."
         Symantec intends to utilize a Synthetic Lease financing structure to
         acquire CCC2 in exchange for CCC5, and commitments satisfactory to
         Symantec from sources acceptable to Symantec to provide such a
         structure as of the First Closing shall have been obtained by Symantec
         prior to the end of the Feasibility Period.

         5.2.1.8.2 APPLE LEASE TERMINATION. CCC2 is currently occupied by Apple
         Computer as "Tenant" pursuant to a lease (the "Apple Lease") that has
         an expiration date of October 31, 2000 and a right of renewal for an
         additional two (2) years. Symantec intends during the Feasibility
         Period to seek a commitment from Apple Computer pursuant to which
         commitment Apple Computer agrees to terminate the Apple Lease and
         vacate CCC2 not later than a date satisfactory to Symantec, and such a
         commitment in form and content satisfactory to Symantec should have
         been obtained prior to the end of the Feasibility Period. Symantec
         covenants and agrees that it shall not have any meetings or discussions
         with representatives of Apple Computer (nor shall Symantec send Apple
         Computer any written proposals) without first notifying TST and
         affording TST the right to be present at such meetings or discussions
         or to first review and approve (in its sole and absolute discretion)
         any such written proposals. No agreement between Symantec and Apple
         Computer shall bind TST or Travelers or otherwise affect Building CCC2,
         and any such agreement shall be expressly conditioned upon Symantec
         having acquired CCC2 at the First Closing.

         In the event a termination agreement is reached with Apple that is
         conditioned upon a termination payment being made to Apple, Symantec
         and TST agree to contribute at the First Closing up to Two Hundred
         Thousand Dollars ($200,000) each toward such termination payment.

   5.2.2.  CONDITION OF TITLE.

      5.2.2.1. TITLE REVIEW; RESPONSIBILITY OF EACH PARTY. The Parties agree
      that all matters regarding title with respect to all Properties shall be
      resolved during the Feasibility Period. Each Party shall be responsible
      for evaluating the condition of title for the Property(ies) to be acquired
      by such Party. The Election to Proceed required to be given pursuant to
      Section 5.2.3 with respect to each Property requires that the Party giving
      the Election to Proceed identify a Title Pro Forma that such Party will
      accept as a condition to the Closing for such Property. During the
      Feasibility Period, each Party shall be responsible for obtaining from the
      Title Insurer such title information as each Party shall deem appropriate
      and to obtain the binding commitment of the Title Insurer as to the form
      of Title Policy including endorsements that the Title Insurer will deliver
      at Closing which commitment shall 


                                       18
   19

         only be subject to the effect of encumbrances to title occurring
         subsequent to the date of such Title Pro Forma.

      5.2.2.2. PROCEDURES FOR TITLE OBJECTIONS.

         5.2.2.2.1 DURING FEASIBILITY PERIOD. During the Feasibility Period, if
         either Party objects to an exception to title with respect to a
         Property controlled by the other Party, such objecting Party may
         identify such title objection and make written request that the other
         Party cure such title objection. Such other Party may, but shall not be
         obligated to respond to such request, provided, however, that the
         Transferor must agree to remove any voluntary monetary liens or
         encumbrances created or suffered by Transferor. If such title
         objections are not cured prior to the end of the Feasibility Period,
         but such other Party has agreed in writing given prior to the end of
         the Feasibility Period to use its best efforts to cure such title
         objection prior to the Closing, then the Election to Proceed may be
         conditioned upon the issuance by the Title Insurer of a Title Policy in
         the form of the Title Policy Pro Forma subject only to the cure of such
         title objection as a condition to Closing. If a Party requests that the
         other Party agree to cure a title objection and such other Party either
         does not respond to such request prior to the end of the Feasibility
         Period or declines to cure such title objection, then such Party making
         such request may either terminate this Agreement with respect to the
         Property which is the subject of such request or give its Election to
         Proceed with respect to such Property, in which latter event such
         requesting Party shall have agreed to accept such Property at the
         Closing without a cure of such title objection and in accordance with
         the Title Policy Pro Forma identified in its Election to Proceed.

         5.2.2.2.2 SUBSEQUENT ENCUMBRANCES. If a Title Pro Forma is amended (an
         "Amendment") to reflect the existence of any exceptions to title
         arising subsequent to the Feasibility Period with respect to a
         particular Property, the Transferee Party shall have three (3) business
         days from the date of Transferee Party's receipt of such Amendment in
         which to approve, in writing, any such easements, encumbrances, or
         other exceptions or requirements shown thereon which were not disclosed
         by the applicable Title Pro Forma or a previous Amendment (the
         "Additional Encumbrances"). If such Transferee does not approve such
         Amendment within such three (3) business day period, such Additional
         Encumbrances shall be deemed disapproved. If such Transferee Party
         approves the Additional Encumbrances within such time period, then the
         Additional Encumbrances shall be deemed Permitted Exceptions and the
         Title Pro Forma identified on Exhibit L for the Property affected shall
         be deemed amended to incorporate the Amendment. If the Additional
         Encumbrances are not approved, then, except with respect to monetary
         liens or encumbrances voluntarily created by the Transferor Party, such
         Transferor Party shall have the right to terminate this Agreement in
         accordance with the provisions of the Section hereof entitled "Non
         Default Termination" unless Transferor Party has elected (i) in the
         next succeeding sentence. Transferor Party, within three (3) business
         days after Transferee Party's written or deemed disapproval, shall, in


                                       19
   20

         Transferor Party's sole discretion: (i) notify Transferee Party in
         writing that Transferor Party will eliminate the Additional
         Encumbrances before the Closing; or (ii) notify Transferee Party that
         unless Transferee Party waives its disapproval of the Additional
         Encumbrances within three (3) business days after receipt of Transferor
         Party's notice, Transferor Party shall cancel this Agreement; provided,
         however, that the Transferor must agree to remove any monetary liens or
         encumbrances voluntarily created or suffered by Transferor. If
         Transferor Party elects (i) above, Transferor Party shall eliminate the
         Additional Encumbrances prior to the Closing. If Transferor Party
         elects (ii) above, this Agreement shall automatically terminate upon
         the expiration of the 3-day period referenced therein unless Transferee
         Party notifies Transferor Party that it waives Transferee Party's
         disapproval of the Additional Encumbrances, in which case the
         Additional Encumbrances shall be deemed Permitted Exceptions and the
         Title Pro Forma identified on Exhibit L for the Property affected shall
         be deemed amended to incorporate the Amendment.

         5.2.2.2.3     COST OF TITLE INSURANCE.

         Each Transferee Party shall bear all costs of the title insurance
         required as a condition of the First Closing. With respect to the
         Second Closing as to WHQ, Symantec shall be responsible for the costs
         of a CLTA owner's policy and TST shall be responsible for any costs of
         title insurance in excess thereof; provided, however, if any Title Pro
         Forma includes a mechanics lien endorsement, the Transferor Party with
         respect to the Closing in which such a Title Pro Forma is required
         shall be responsible for providing such indemnities as may be required
         by the Title Insurer as a condition to providing such endorsement.

   5.2.3. ELECTION TO PROCEED. By giving an Election to Proceed with respect to
   a Property or Properties, the Party giving such Election to Proceed shall be
   deemed to have agreed at the Closing with respect to the Property covered by
   such Election to Proceed as follows: (i) to accept such Property in its then
   "As Is" condition except for such representations are warranties given by the
   Transferor Party and are intended to survive the Closing and (ii) to accept
   title to such Property in the condition specified in the Title Pro Forma
   specified in such Election to Proceed. The Title Pro Forma specified in the
   Election to Proceed shall be incorporated into the Condition of Title at
   Closing on Exhibit L with respect to the applicable Property.

      SECTION 2.02 OF SCHEDULE "2" AND THAT EACH OF SYMANTEC AND TST HAVE HAD
      THE CHANCE TO CONSULT ITS COUNSEL ABOUT ITS MEANING AND SIGNIFICANCE AND
      AGREES TO ITS TERMS.

Even though the First Closing will occur some time after the occurrence of
Substantial Completion of Building CCC5, TST acknowledges that in most cases the
time period for any warranties given by the Building CCC5 Contractor or any of
the subcontractors or contractors will commence to run upon the date of
Substantial Completion set forth in the Certificate of Substantial Completion.

6.4. SURVIVABILITY. Except where a longer or shorter period is specified
elsewhere in this Agreement, each Party's representations, warranties and
indemnities (if any) shall survive the Closing and the delivery of the Grant
Deed, but shall terminate on the date which is one (1) year after each Closing
except as to claims and matters as to which either Party has given specific
notice to the other within such one (1) year period. Any claim against a Party
with respect to any breach of such Party's representations, warranties and
indemnities (if any) as to which notice has been given to a Party within such
one (1) year period and which has not been satisfied shall be deemed discharged


                                       27
   28

unless the party making such claim shall have pursued such claim pursuant within
six (6) months following the end of such one (1) year period.

                                    ARTICLE 7
                                    COVENANTS

7.1. INSPECTION RIGHTS. Subject to the rights of Apple Computer pursuant to the
terms and provisions of the Apple Lease, each Party and its agents and
contractors shall have the right to enter on the Property ("Access") to inspect
it and conduct tests and each Party hereby agrees to indemnify the other Party
and the fee owners of the Property from any liability, loss, cost or damage
resulting from physical damage caused by a Party or its agents during such entry
or inspection; provided, however, each Party agrees not to perform any drilling
without giving the other Party reasonable notice of not less than one (1) full
business day. Either Party may contact any federal, state or local governmental
authority or agency to investigate any matters relating to the Property. With
respect to the rights of Apple Computer pursuant to the Apple Lease, TST agrees
to use its commercially reasonable efforts to cause Apple Computer to permit
inspections by Symantec and its agents as contemplated above.

7.2. DISCOVERIES. Each Party acknowledges that it may discover Hazardous
Materials on, under or about the Property or some other fact or condition
pertaining to the Property which a Party believes may negatively impact the
value or development potential of the Property in some manner (the "Discovery").
If either Party makes any such Discovery prior to Closing but nevertheless
completes the acquisition of a particular Property, the Party acquiring such
Property further covenants and agrees to refrain from bringing any claim for
damages, causes of action, or lawsuit against other Party or the other Party's
Related Parties, or their successors, heirs, contractors, engineers and/or
attorneys which in any way alleges that the other Party failed to disclose the
existence of such Hazardous Materials or other fact or condition which was
discovered prior to Closing by the Party completing such acquisition. The
foregoing shall not limit a Party's right to seek legal or equitable remedies
against the other Party for such other Party's breach of its representations,
warranties or covenants contained in this Agreement unless the Party completing
such acquisition had actual knowledge of the material facts relating to such
breach prior to Closing.

   7.2.1. TERMINATION UPON CERTAIN DISCOVERIES. Each Party acknowledges that
   during the Feasibility Period, it will have sufficient time to make such
   investigations with respect to the Property as it deems appropriate. Once a
   Party gives such Party's Election to Proceed pursuant to Section 5.3.1.1 with
   respect to a particular Property, any failure by such Party to close on
   account of a later Discovery shall constitute a default by such Party and the
   provisions of Section 8.5 shall apply. Notwithstanding the foregoing, if
   either Party fails to close following its Election to Proceed on account of a
   Discovery of a "Material Hazardous Material Problem" which was not disclosed
   (and could not reasonably have been discovered upon the performance of
   customary environmental due diligence during the Feasibility Period), such
   failure to close shall constitute a non-default termination pursuant to
   Section 8.8. As used herein, "Material Hazardous Material Problem" shall
   exist only if a Party gives written notice to the 

                                       28
   29

   other Party signed by an officer of the Party giving the notice at the
   level of Vice President or Senior Managing Director or above which
   notice states that subsequent to the end of the Feasibility Period, (i)
   such Party has Discovered that there exists with respect to the Property
   a Hazardous Material issue that such Party believes will materially
   impact such Party's business operations if such Party completes the
   acquisition of the Property pursuant to this Agreement and (ii)
   describes such Hazardous Material issue with particularity.

7.3. OPERATION OF THE PROJECTS. The Parties hereby covenant and agree that from
the Agreement Date until either the Closing with respect to a particular
Property occurs or this Agreement is terminated, that the Properties will be
maintained and operated as set forth below:

   7.3.1. CCC5. Symantec shall continue to manage the construction of the
   Building CCC5 as Sumitomo Bank Leasing and Finance, Inc.'s construction agent
   and build-to-suit lessee under the Building CCC5 General Contract in
   accordance with Symantec's current practices with a view toward achieving
   Substantial Completion of Building CCC5 in accordance with the Building CCC5
   Plans as soon as practicable. So long as this Agreement has not been
   terminated with respect to CCC5, Symantec agrees that without the prior
   written consent of TST: (i) it shall not cause any leases to be executed with
   respect to any portion of Building CCC5 and (ii) it shall not construct or
   install any improvements, in the nature of "tenant improvements" or
   otherwise, or install any furniture or fixtures, except as shown on the
   Building CCC5 Plans. Without TST's prior approval (which approval shall not
   be unreasonably withheld or delayed) Symantec shall not make any changes to
   the Building CCC5 Plans or amend or modify the Building CCC5 Architectural
   Contract or the Building CCC5 General Contract if any single such change will
   result in an increase or decrease in the cost of construction of Building
   CCC5 by $100,000 or if all such changes cumulatively will exceed $250,000.

   7.3.2. CCC2. TST shall continue to manage CCC2 in accordance with TST's
   current practices as Traveler's managing agent as an office building occupied
   entirely by Apple Computer. So long as this Agreement has not been
   terminated, TST agrees (but subject to the rights of Travelers as the fee
   owner of the Property as to which TST shall have no liability of
   responsibility) that without the prior written consent of Symantec: (i) it
   shall not amend, extend or modify in any material way the Apple Lease, (ii)
   it shall not enter into any new leases with respect to any portion of CCC2,
   (iii) except as necessary to fulfill its obligations under the Apple Lease or
   as reasonably prudent in the judgment of TST as the property manager for a
   first class office building, it shall not construct any improvements or
   modify the building in any way.

   7.3.3. WHQ. Symantec shall continue to manage WHQ as an office building
   housing its business operations in accordance with Symantec's current
   practices and agrees to manage to completion, at its sole cost and expense,
   the WHQ Exterior Lighting Contract provided that without TST's written
   consent, Symantec shall not enter into any leases or occupancy agreements for
   any space within WHQ.

                                       29
   30


   7.3.4. ALL PROPERTIES; SERVICE CONTRACTS. Without limiting the generality of
   the foregoing, each Party agrees that from and after the date of this
   Agreement that with respect to the Properties controlled by each Party (but
   subject to the rights of Travelers as the fee owner of the CCC2 as to which
   TST shall have no liability or responsibility), each Party will not enter
   into new service or other contracts or amendments to existing service or
   other contracts unless such new or amended service or other contracts contain
   clauses permitting cancellation of such contracts on not more than thirty
   (30) days notice without a termination fee.

      7.3.4.1. DURING FEASIBILITY PERIOD; EXISTING SERVICE CONTRACTS. During the
      Feasibility Period, if either Party objects to an existing service
      contract with respect to a Property controlled by the other Party, such
      objecting Party may identify such service contract and make written
      request that the other Party terminate such service contract as of the
      Closing applicable to such Property. Such other Party may, but shall not
      be obligated to respond to such request. If such service contracts are not
      terminated prior to the end of the Feasibility Period, but such other
      Party has agreed in writing given prior to the end of the Feasibility
      Period to use its best efforts to terminate such service contracts prior
      to the Closing, then the Election to Proceed may be conditioned upon the
      termination of such service contracts as a condition to Closing. If a
      Party requests that the other Party agree to terminate a service contract
      and such other Party either does not respond to such request prior to the
      end of the Feasibility Period or declines to terminate such service
      contracts, then such Party making such request may either terminate this
      Agreement with respect to the Property which is the subject of such
      request or give its Election to Proceed with respect to such Property, in
      which latter event such requesting Party shall have agreed to accept such
      Property at the Closing without a termination of such service contracts.

7.4.    OTHER COVENANTS. Each Party hereby further covenants and agrees as 
        follows:

   7.4.1. COVENANTS OF BOTH PARTIES. Both Parties covenant and agree as follows:

      7.4.1.1. PROPERTY INSPECTION AND DOCUMENTS. To reasonably cooperate with
      the other Party in the inspection of the Property and the Property
      Documents. Within ten (10) days after the Agreement Date, each Party shall
      deliver to the other Party all Property Documents that, to the best of the
      delivering Party's actual knowledge, are in the delivering Party's
      possession or are under the delivering Party's control, including all
      third-party inspection reports.

   7.4.2. SYMANTEC'S COVENANTS. Symantec hereby further covenants and agrees to
   execute and deliver at the First Closing and the Second Closing, as
   applicable, the documents described as conditions in Sections 5.4.2.3,
   5.4.2.4, 5.4.2.6, 5.4.3.1, and 5.4.3.2.

   7.4.3. TST'S COVENANTS. TST hereby further covenants and agrees to execute
   and deliver at the First Closing and the Second Closing, as applicable, the
   documents described as conditions in Sections 5.3.2.2.2, 5.3.2.2.3,
   5.3.2.2.4, and 5.3.2.2.6.

            Building CCC5 prior to the First Closing;

        7.5.1.2. NO RIGHT TO CONSTRUCT TENANT IMPROVEMENTS. TST may not enter
        Building CCC5 and construct tenant improvements for tenants under leases

        7.5.2. WHQ TENANT IMPROVEMENTS. No tenant improvements or other
        construction shall be undertaken by TST with respect to WHQ prior to the

9.2. INCORPORATION OF EXHIBITS. All schedules and exhibits attached hereto and
referred to herein are incorporated in this Agreement as though fully set forth

9.3. RIGHT OF FIRST REFUSAL AND RIGHT OF FIRST OFFER. If, and only if, TST or

completes the Second Closing and acquires WHQ, then with respect to each of CCC2
and CCC1, TST shall have the following special rights:

        9.3.1. RIGHT OF FIRST REFUSAL. TST shall have a "Right of First Refusal"
        to acquire CCC2 and CCC1 for a period ending at the end of 3 (three)
        years following the First Closing as to CCC2.

        9.3.2. RIGHT OF FIRST OFFER. TST shall have a "Right of First Offer" for
        a period ending at the end of 5 (five) years following the time when the
        Right of First Refusal granted pursuant to Section 9.3.1 has ended.

        9.3.3. PROCEDURES FOR RIGHT OF FIRST REFUSAL AND RIGHT OF FIRST OFFER.
        TRIGGERING EVENT. For purposes of this Section 9.3.3, a "Triggering
        Event" shall mean: (i) in the case of the Right of First Refusal, the
        receipt by Symantec of a bona fide written offer (a "Purchase Offer") to
        purchase either or both CCC1 or CCC2 (each an "Affected Property" and
        collectively, the "Affected Properties") and (ii) in the case of the
        Right of First Offer, thirty (30) days before Symantec 

                                       35
   36

        gives written notice to parties other than TST of Symantec's intent to
        sell (an "Intent to Sell") either or both Affected Properties.

        9.3.3.2. TRIGGERING EVENT OFFER NOTICE. Within ten (10) days following
        the occurrence of a Triggering Event, Symantec shall give notice to TST
        (the "Triggering Event Offer Notice") listing the principal terms (the
        "Triggering Event Terms") of the Intent to Sell or including a copy of
        the Purchase Offer, as the case may be.

        9.3.3.3. TRIGGERING EVENT PURCHASE NOTICE. TST shall have ten (10)
        business days following the Triggering Event Offer Notice within which
        to notify Symantec that TST desires to purchase the Affected Property
        upon the Triggering Event Terms (the "Triggering Event Purchase
        Notice").

        9.3.3.4. NO TST PURCHASE. If TST either notifies Symantec that TST
        declines to purchase the Affected Property upon the Triggering Event
        Terms or fails to give Symantec a Triggering Event Purchase Notice,
        Symantec shall be free to enter into and complete a sale of the Affected
        Property upon the Triggering Event Terms without any further notice to
        TST. In such event, TST shall have no further Right of First Refusal or
        Right of First Offer with respect to the Affected Property (but such
        rights shall continue with respect to the other Property) so long as:

         (a)   within six (6) months following the Triggering Event Offer
               Notice, Symantec enters into a binding agreement with a third
               party for the purchase and sale of the Affected Property
               substantially in accordance with the Triggering Event Terms and
               otherwise upon "net economic terms"(as hereinafter defined) of
               not less than ninety-five percent (95%) of the net economic terms
               offered to TST in the Triggering Event Offer Notice (the "Third
               Party Agreement), and

         (b)   thereafter such sale closes pursuant to the terms of the Third
               Party Agreement;

         (c)   provided, however, if the purchase and sale of the Affected
               Property does not close pursuant to the terms of the Third Party
               Agreement within a reasonable time following the date for closing
               set forth in the Third Party Agreement and/or if the Third Party
               Agreement is terminated, the Affected Property shall again be
               subject to the Right of First Refusal and the Right of First
               Offer;

         (d)   provided, further, if the Triggering Event Terms did not include
               seller financing, and if Symantec later offers seller financing,
               it shall be deemed that the Third Party Agreement is not
               substantially in accordance with the Triggering Event Terms;

        (e)     for purposes of this Section 9.3.3.4, "net economic terms' shall
                mean the purchase price reduced by the monetary value of (i) any
                credits or offsets 

                                       36
   37

                to be given to the buyer at closing, (ii) the present value
                (calculated using a discount rate of ten percent (10%)) of any
                rents or other amounts to be paid by Symantec to the buyer
                following the closing, and (iii) if seller financing is part of
                the Triggering Event Terms, the present value (calculated using
                a discount rate of ten percent (10%)) of the amount by which the
                periodic payments to be made pursuant to the financing terms
                which are part of the Triggering Event Terms are less than the
                actual financing terms set for in the Third Party Agreement.

      9.3.3.5. YES TST PURCHASE. If TST gives a Triggering Event Purchase
      Notice, but either of the following occur, such Affected Property shall no
      longer be subject to either the Right of First Refusal or the Right of
      First Offer:

         (a) within sixty (60) days following such Triggering Event Purchase
             Notice, and despite the parties' good faith commercially reasonable
             efforts, Symantec and TST have not executed a mutually acceptable
             binding agreement which (except for the specific terms set forth in
             the Triggering Event Offer Notice) shall be on substantially the
             same terms, conditions, representations and warranties as set forth
             in this Agreement (the "Affected Property Agreement") providing for
             the purchase by TST of the Affected Property; provided, however, if
             the parties have not executed the Affected Property Agreement
             within such sixty (60) day period but are continuing to use good
             faith commercially reasonable efforts to do so, either party may,
             by notice to the other party given prior to the end of such sixty
             (60) day period, assert that such party believes that with the
             continuation of such good faith commercially reasonable efforts,
             the parties are likely to execute the Affected Property Agreement
             within an additional thirty (30) days, in which event such sixty
             (60) day period shall be so extended for an additional thirty (30)
             days;

         (b) Symantec and TST enter into an Affected Property Agreement, but the
             purchase and sale of the Affected Property does not close pursuant
             to the terms of the Affected Property Agreement within a reasonable
             time following the date for closing set forth in the Affected
             property Agreement and/or if the Affected property Agreement is
             terminated for reasons other than the breach or default of
             Symantec.

      9.3.3.6. RIGHT TO ASSIGN. The provisions of Section 3.4 shall apply to the
      exercise by TST of the rights set forth in this Section 9.3.

                                   ARTICLE 10
                      LOSS OR CONDEMNATION PRIOR TO CLOSING

Notwithstanding the provisions of the Uniform Vendor and Purchaser Risk Act, the
parties hereto agree that if a loss to all or any portion of the Property occurs
prior to Closing from any cause whatsoever, including, without limitation, due
to a casualty or a taking under the power of eminent domain, the following
provisions will apply:

                                       37
   38

10.1. LOSS DOES NOT EXCEED MATERIALITY LIMIT. In the event of any condemnation
or taking of the Property, or loss or damage by fire or other casualty to the
Property prior to the Closing which does not exceed the Materiality Limit, the
Closing shall occur just as if such condemnation, loss or damage had not
occurred, and the Transferor Party shall assign to the Transferee Party all of
Transferor Party's interest in any condemnation actions and proceeds, or deliver
to Transferee Party any and all proceeds paid to Transferor Party by Transferee
Party's insurer with respect to such fire or other casualty (together with the
amount of any deductible); provided, however, that Transferor Party shall be
entitled to retain an amount of such insurance proceeds equal to Transferor
Party's reasonable expenses, if any, incurred in repairing the damage caused by
fire or other casualty (together with the amount of any deductible). Each Party
shall maintain "all risk" replacement value insurance coverage in place on the
Property at all times prior to the Closing. During the Feasibility Period, each
Party has reviewed the other Party's current insurance policies for the Property
(or the relevant portions thereof) and agrees that such policies, if continued
through Closing, will satisfy such requirements for "all risk" replacement value
insurance coverage within the meaning of the preceding sentence. At Closing, in
the case of a fire or other casualty, Transferor Party shall give Transferee
Party a credit on the Purchase Price equal to the lesser of the estimated cost
of restoration or the amount of the deductible.

10.2. LOSS EXCEEDS MATERIALITY LIMIT. In the event of any condemnation of all or
a part of the Property, or loss or damage by fire or other casualty to the
Property prior to the Closing which exceeds the Materiality Limit, at Transferee
Party's sole option, either:

   10.2.1. TERMINATE AGREEMENT. Elect to terminate this Agreement in accordance
   with the Section 8.8 if Transferee Party shall so notify Transferor Party in
   writing within ten (10) days of Transferee Party having actual knowledge of
   the casualty or condemnation; or

   10.2.2. CLOSE. If Transferee Party shall not have timely notified Transferor
   Party of its election to terminate this Agreement in accordance with
   Subsection (a) above, the Closing shall occur just as if such condemnation,
   loss, or damage had not occurred, without reduction in the Purchase Price,
   and Transferor Party shall assign to Transferee Party all of Transferor
   Party's interest in any condemnation actions and proceeds or deliver to
   Transferee Party any and all proceeds paid to Transferor Party by Transferor
   Party's insurer with respect to such fire or other casualty; provided,
   however, that Transferor Party shall be entitled to retain an amount of such
   insurance proceeds equal to Transferor Party's reasonable expenses, if any,
   incurred in repairing the damage caused by such fire or other casualty. At
   Closing, in the case of a fire or other casualty, Transferor Party shall give
   Transferee Party a credit on the Purchase Price equal to the lesser of the
   estimated cost of restoration or the amount of the deductible.

                         REPRESENTATIONS AND WARRANTIES

        hereby makes the following representations and warranties to each
        Transferee Party, except as set forth in Schedule 2A and except to the
        extent that Transferee Party makes any Discovery:

(1)     Unqualified Representations and Warranties. The representations and
        warranties set forth below in this Section 2.01(1) are given by
        Transferor Party without qualification pursuant to their terms:

        (a)     Other Agreements. Neither this Agreement, nor anything provided
                to be done hereunder, violates or shall violate any contract,
                agreement or instrument to which Transferor Party is a party, or
                to the best of Transferor Party's actual knowledge, which
                affects Transferor Party's Property or any portion thereof;

        (b)     Organization and Standing. Transferor Party is an entity of the
                type described in the opening paragraph of the Agreement, duly
                organized, validly existing and in good standing under the laws
                of the State of its formation, has, or with respect to TST, as

        (c)     No Other Sales. Transferor Party has not entered into, and has
                no legal notice of any claim relating to, any other contracts
                for the sale of all, any portion of, or any interest in
                Transferor Party's Property, and Transferor Party has not
                granted, and has no legal notice of any claim relating to, any
                rights of first refusal or options to purchase the all, any
                portion of, or any interest in Transferor Party's Property;

        (d)     Approvals. Transferor Party has not received written notice (or,
                if any such notice has been received the violation described in
                such notice has been cured) that any consent, authorization,
                variance, license, permit, or approval (collectively, the
                "Approvals") relating to or required for the operation or
                occupancy of Transferor Party's Property and required in order
                for Transferor Party to carry out the transactions contemplated
                hereby has not been validly and unconditionally obtained (or, if
                there existed any condition with respect thereto, such condition
                has been satisfied) or is not in full force and effect.
                Materially true, accurate, and complete copies of all Approvals
                in Transferor Party's possession have been, or will be,

                of the Property Documents. All fees, charges, and other payments

                except in the ordinary course of business, there will be no
                application for any Approval which is pending. Transferor Party
                shall have no liability with respect to this Subsection (d) to

                Transferee Party conducted its due diligence;

        (e)     Tenant Agreements. Other than the Leases and the Permitted
                Encumbrances, there are no other lease amendments or agreements
                between Transferor Party and any tenant. Transferor Party has
                made no other agreements (whether written or oral) in the nature
                of a lease affecting Transferor Party's Property that has not
                expired or terminated or will not expire or terminate as of the
                Closing;

        (f)     No Continuing Employees. There are no persons employed in
                connection with the use, operation, maintenance or management of
                Transferor Party's Property whom the Transferee Party would be
                obligated to retain or compensate or provide benefits for after
                the Closing, unless Transferee Party obligates itself to do so
                by a separate written agreement;

        (g)     Personal Property. A materially true and accurate list of the
                personal property of material value used in connection with the
                operations of Transferor Party's Property shall be attached as
                Exhibit K hereto within thirty (30) days of the Agreement Date,
                and a true and accurate list of such personal property of
                material value, not materially varying from the attached, will
                be updated as of the Closing Date and will be attached to the
                Bill of Sale delivered to Transferee Party at Closing. All of
                such personal property of material value is owned by Transferor
                Party in its own name. As of the Closing, none of such personal
                property of material value will be leased or be subject to any
                liens or conditional sales contracts (personal property
                complying with such representations and warranties is referred
                to herein as the "Personal Property");

(2)     Qualified Representations and Warranties. The representations and
        warranties set forth below in this Section 2.01(2) are given by
        Transferor Party pursuant to their terms and to the best knowledge of

                Agreement Date. New Lease Reports, all updated as of the Closing
                Date will be delivered to Transferee Party at Closing, and will

                of the Tenants pursuant to the Leases, (c) the Tenants are not

                received by Transferor Party from any of the tenants in
                Transferor Party's Property;

        (b)     No Actions. To the best of Transferor Party's knowledge, there
                are no pending, threatened or contemplated actions, suits,

             EXCEPTIONS TO SYMANTEC'S REPRESENTATIONS AND WARRANTIES


A.      CCC5.

        -       At the time of the acquisition of the CCC5 Property by
        Symantec's designee in 1997, the Property was used as a surface parking
        area by users within Cupertino City Center.

        -       As a condition to the acquisition of the Property, Symantec made
        various commitments to other owners or property within Cupertino City
        Center (and certain of their lenders) to provide extra parking
        facilities within the parking structure to be built on the Property as
        part of the Building CCC5 project to accommodate the parking needs of
        such other owners and users.

        -       Among other documents evidencing the right of such other owners
        and users, is that certain Parking Easement and Relocation Agreement
        recorded February 5, 1997 as Document #13602281 in the Official Records
        and Santa Clara County (the "Parking Easement and Relocation
        Agreement").

        -       In addition, to the Parking Easement and Relocation Agreement,
        certain parking rights have been granted pursuant to recorded easements
        in favor of the apartment project located across the entry driveway to
        Building CCC5 and in favor of the WHQ Property.

        -       In order to accommodate the various parking requirements, the
        parking structure was expanded below ground beyond the parcel boundaries
        for the Property. Various easements and other agreements were obtained
        from affected parties in order to authorize such expansion of the
        parking structure and the installation and maintenance of (i) electrical
        and communications infrastucture within such expanded area and (ii)
        landscaping treatments.

        -       In order to facilitate the construction process, a "tie-back
        easement" was obtained from a neighboring property owner.

        -       The foregoing is not intended to be a comprehensive list or to
        serve as substitute for TST's thorough investigation of title and all
        other matters relating to the CCC5 Property.

A.      WHQ.


                The following statements describe relevant information relating
        to WHQ of which TST should be aware as TST conducts its investigations
        during the Feasibility Period:

        -       3rd Floor, South Wing has several roof leaks

        -       3rd Floor, North Wing A/C system has a large pressure drop



                                       49
   50

        -       Building carpets need replacing

        -       Parking lot stall lines need repainting



                                       50
   51

                                   SCHEDULE 2B
               EXCEPTIONS TO TST'S REPRESENTATIONS AND WARRANTIES

        Cupertino City Center Buildings ("Buildings") and its affiliates own
certain properties within the, Cupertino City Center, and is effectively by
succession the Declarant under that certain Declaration of Covenants, Conditions
and Restrictions and Grant of Easements for Cupertino City Center dated October
2, 1985 (the "Original Declaration").

        Pursuant to the terms of the Original Declaration a Parking Structure
was designated for Lot 3 of Tract 7734, to contain 1,232 spaces, to be used by
the owners of Lots 1, 2, and 4. CCC2 is located on Lot 2. The original
Declaration also provided that the owner of each Lot would be allocated a
non-exclusive easement for the use of "such a number of parking spaces therein
as are reasonably necessary to satisfy the Minimum Parking Ratio applicable to
each such Lot." TST believes that the contemplated number of parking spaces in
the Original Declaration is not sufficient to satisfy the Minimum Parking Ratio
for the building to be built on Lots 1, 2, and 4 at such time as all three Lots
are fully developed. As of the Agreement Date, Lot 4 remains undeveloped. A
Parking Structure has been built on Lot 3, which contains approximately 1,265
spaces.

        On February 2, 1987, through a recorded Deed of Trust, Buildings granted
to the Travelers Insurance Company ("Travelers"), the present fee owner of CCC2,
a non-exclusive easement to park 494 automobiles in the Parking Structure. In
that Deed of Trust, Buildings warranted and represented that it would not grant
easements for the benefit of other properties for parking in the Parking
Structure that would overburden the Parking Structure or would violate
applicable zoning laws.

        On April 15, 1987, Buildings granted to the owner of Lot I in Tract 7734
a non-exclusive easement for parking 580 automobiles in the Parking Structure
pursuant to an Agreement and Grant of Permanent Easement, Thereafter, on August
28, 1987, the Original Declaration was amended by a First Amendment to
Declaration (the "First Amendment") to incorporate nine additional Lots in the
adjoining Tract 7953 into the Cupertino City Center complex. The First Amendment
restricted the Declarant's right to grant further parking rights in the Parking
Structure without the consent of the owners and mortgagees of Lots 1 and 2 of
Tract 7734, which would include Travelers as the then mortgagee of Lot 2.

        On November 1, 1989, in a Deed of Trust for the benefit of Teachers
Insurance & Annuity Association of America ("TIAA"), Buildings granted a
non-exclusive easement for parking 193 automobiles within the Parking Structure
for the benefit of Lots 2 and 3 of Tract 7953 This increased the parking
allocation within the Parking Structure to 1,267 spaces. The subject TIAA Deed
of Trust provided in part that the grant of easement had received all necessary
approvals and consents, including the consents of owners and mortgagees of Lots
I and 2 of Tract 7734. TST has no knowledge whether Travelers was consulted or
provided any consent in this regard. 




                                       51
   52

        On or about October 3, 1996, a Parking Easement and Relocation
Agreement (the "Relocation Agreement") was entered into between Buildings, TIAA,
and several other parties (and which was approved and consented to by Symantec
on September 30, 1996), under which certain parking rights benefiting Lots 2 and
3 in Tract 7953 can be temporarily relocated either to the Parking Structure or
to alternate parcels (Lots 1 and 6 in Tract 7953), The Relocation Agreement
relates to parking rights for a total of 255 additional automobiles, The term of
this temporary parking easement is three years from the date that Buildings
sends a notice to the applicable parties designating which area is to be
burdened with temporary additional parking. As of the Agreement Date, TST
believes that Travelers has not received any such notice, so it is presumed that
temporary parking rights in the Parking Structure have not been granted by
Buildings pursuant to the Relocation Agreement.

        TST further believes that Travelers is not aware of any effort to gain
Travelers consent to the Relocation Agreement, as required under the First
Amendment. However, TST is aware that on February 7, 1997, in a document
entitled Second Amendment to Declaration (the "Second Amendment"), Buildings
purported to modify the First Amendment by retroactively providing that the
consent and approval requirements for the granting of additional parking rights
shall not apply to the Relocation Agreement and "any parking temporarily
relocated after the date hereof from Lot 4 of Tract 7734 on terms and conditions
which are similar to those contained in the [Relocation Agreement.]"

        TST believes that Travelers was not consulted and did not consent to the
Second Amendment. While the original Declaration specifies that Buildings (as
the Class B member) has the sole right to amend the Declaration, it also states
that any amendment that would have a materially adverse effect on any mortgagee
requires the consent of such mortgagee. TST is not aware of mortgagee consent to
the Second Amendment. Moreover, according to the Declaration, in the event a
mortgagee succeeds to the ownership interest of any so-called Class B member's
voting rights, then that Mortgagee also succeeds to the Class B member's voting
rights. Accordingly, Travelers, upon its foreclosure of CCC2 arguably succeeded
to the Class B member voting rights of the original owner of Lot 2. Travelers
was not given the opportunity to vote in connection with the Second Amendment.

        TST HEREBY DISCLAIMS ANY REPRESENTATION OR WARRANTY THAT THE PURCHASER
OF LOT 2 AND CCC2 WILL HOLD AN IRREVOCABLE EASEMENT TO PARK 494 AUTOMOBILES
WITHIN THE PARKING STRUCTURE OR ANY REPRESENTATION OR WARRANTY THAT THE PARKING
STRUCTURE IS ADEQUATE TO SATISFY THE MINIMUM PARKING REQUIREMENTS FOR EACH LOT
WITH RIGHTS TO PARK THEREIN.

3.03    Prorations. All items of revenue and expense from the Projects shall be
        prorated as of the Closing Date. Without limiting the foregoing:

        (a)     All prorations shall be based on a 30-day month and a 360-day
                year. All items of income and expense for the date on which
                Closing occurs shall be allocated to Transferee Party.

        (b)     Real property taxes and assessments shall be prorated between
                Transferee Party and Transferor Party based on the latest
                available tax information. In the event any supplemental tax
                bill is issued following the Closing Date, Transferor Party
                shall pay to Transferee Party all additional amounts applicable
                to the time prior to the Closing Date upon written request of
                Transferee Party.

                issued as of the Closing Date for all public utility services on
                the Property and there shall be no proration of insurance
                premiums or public utility bills. Any deposits on utilities paid
                by Transferor Party shall be returned to Transferor Party.
                Transferee Party shall cause all utilities to be placed in

        (d)     Rental income actually received from the Property shall be
                prorated as of the Closing Date. Past due rentals shall be
                handled as follows: Transferor Party shall retain the right to
                collect receivables from former tenants who are no longer in
                residence at the Property as of the Closing Date, but Transferee
                Party shall have the right to collect and retain all receivables
                from tenants still in residence on the Closing Date. Transferor
                Party shall receive a credit from Transferee Party at Closing
                for: (1) 100% of receivables less than thirty (30) days past due
                from Tenants that are still in residency at the Property as of
                the Closing Date; and (2) 60% of receivables less than sixty
                (60) days but thirty (30) or more days past due from Tenants
                that are still in residency at the Property as of the Closing
                Date. The amount of all security deposits shall be deducted from
                Transferor Party's account at Closing. By execution of the
                Closing Statement, Transferor Party shall be deemed to have
                represented and warranted that the amount of security deposits
                so deducted from Transferor Party's accounts constitutes the
                entire amount of security deposits from tenants in the Property.

3.04    Costs of Escrow.

        (a)     Transferor Party shall pay the documentary transfer tax and;

                        hereunder.

        (b)     Transferee Party shall pay:

                (i)     All costs not specifically referenced herein customarily

                (ii)    The cost of title coverage for the Property being
                        acquired by such Transferee Party pursuant to Section
                        5.2.2.2.3 of the Agreements;

                (iii)   The cost of any of Transferee Party's other obligations
                        hereunder.

3.05    Escrow Cancellation Charges. In the event that any Closing shall fail to
        occur by reason of the default of either party, the defaulting party
        shall be liable for all escrow cancellation charges. In the event that
        any Closing shall fail to occur for any other reason, Transferee Party
        and Transferor Party shall each be liable for one-half of any escrow
        cancellation charges.

3.06    Default. TIME IS OF THE ESSENCE in this Agreement and if Transferee
        Party or Transferor Party (the "Defaulting Party") fails to deposit any
        of the amounts due pursuant to this Agreement, or to perform any other
        act when due, then the other party (the "Non-Defaulting Party") may give
        notice to the Defaulting Party demanding that such failed performance be
        completed and if such failed performance has not been completed within
        five (5) days following such notice, the Non-Defaulting Party may
        terminate this Agreement by notice in writing to the Defaulting Party
        and Escrow Holder at which time Escrow Holder shall cancel this escrow
        and the Non-Defaulting Party shall thereupon be released from its
        obligations under this Agreement except for any liability under any
        indemnity in the Agreement which expressly survives termination of this
        Agreement and Transferee Party's liability for Transferee Party's Work
        Product (if, and only if, Transferee Party was the Defaulting Party).

3.07    Additional Escrow Instructions. If required by Escrow Holder, Transferee
        Party and Transferor Party shall execute Escrow Holder's usual form of
        supplemental escrow instructions for transactions of this type,
        provided, however, that (a) in the event that any portion of such
        additional escrow instructions shall be inconsistent with the provisions
        of this Agreement, the provisions of this Agreement shall prevail to the
        extent of any such inconsistency; and (b) no provision thereof shall
        have the effect of modifying this Agreement unless it is expressly so
        stated and such express statement is initialed by Transferee Party and
        Transferor Party.

        If any broker or finder makes a claim for a commission or finder's fee
        based upon a contact, dealings, or communications, the party through
        whom the broker or finder makes this claim shall indemnify, defend with
        counsel of the indemnifying party's choice (subject to the reasonable
        approval of the indemnified party), and hold the indemnified party
        harmless from all expense, loss, damage, liability and claims, including

        party having a telecopier machine compatible with the telecopier machine
        of the party sending the notice. Any notice given by telecopier shall be
        deemed delivered when received by the party to whom the telecopy was
        addressed. Any party may change its address or telecopier number for
        notice purposes by giving notice to the other party and to Escrow
        Holder.

       5. All rights which Assignor may have to use any names commonly used in
connection with the Property, if any; and

       6. All rights, which Assignor may have, if any, in and to any tenant

all good will, if any, and any and all other rights, privileges and
appurtenances owned by Assignor and related to or used in connection with the
existing business operation of the Property.

       EXCEPT AS SPECIFICALLY SET FORTH IN SELLER'S REPRESENTATIONS AND
WARRANTIES IN THE AGREEMENT, ASSIGNOR MAKES NO REPRESENTATIONS OR WARRANTIES AS
TO THE PHYSICAL CONDITION OF THE PROPERTY OR THE ASSIGNED PROPERTIES OR THE
SUITABILITY THEREOF FOR ANY PURPOSE THAT ASSIGNEE MAY DESIRE TO USE IT. ASSIGNOR

PHYSICAL CONDITION OF THE ASSIGNED PROPERTIES. ASSIGNEE ACKNOWLEDGES AND AGREES
THAT IT HAS INSPECTED THE ASSIGNED PROPERTIES AND ACCEPTS SAME IN THEIR PRESENT

       Assignor on behalf of itself and its successors and assigns does hereby
agree to indemnify and hold Assignee, its successors and assigns, harmless from
all obligations accruing under the maintenance, service and supply contract
assigned hereby and any liabilities arising thereunder, prior to the date hereof
but not thereafter.

       Assignee on behalf of itself, its successors and assigns, hereby agrees
to assume and perform all obligations accruing under those maintenance, service
and supply contracts that Assignee has specifically elected to assume from and
after the date hereof, and Assignee on behalf of itself, its successors and
assigns does hereby agree to indemnify and hold Assignor, its successors and
assigns, harmless from all such obligations and any liabilities arising
thereunder from and after the date hereof.

       If either party hereto fails to perform any of its obligations under this
Bill of Sale and General Assignment or if any dispute arises between the parties
hereto concerning the meaning or interpretation of any provision of this Bill of
Sale and General Assignment, then the defaulting party or the party not
prevailing in such dispute, as the case may be, shall pay any and all costs and
expenses incurred by the other party on account of such default and/or in
enforcing or establishing its rights hereunder, including, without limitation,
court costs and reasonable attorneys' fees and disbursements. Any such
attorneys' fees and other expenses incurred by either party in enforcing a
judgment in its favor under this Bill of Sale and General Assignment shall be
recoverable separately from and in addition to any other amount included in such
judgment, and such attorneys' fees obligation is intended to be severable from
the other provisions of this Bill of Sale and General Assignment and to survive
and not be merged into any such judgment.
