          the Internal  Revenue  Service,  the Department of Labor, a court,  an

     4. Effective as of April 1, 1997, Section 1.1(A)(16) of the Plan is amended
to read in its entirety as follows:

     "(16)'Highly  Compensated  Employee'  shall  mean any  'highly  compensated
          active employee' or 'highly compensated former employee.'

          (a)  A 'highly  compensated active employee' includes any employee who
               performs  service  for an  Employer or  Controlled  Group  Member
               during the determination year and who, during the look-back year,
               received  compensation  from the  Employer  or  Controlled  Group
               Member in excess of  $80,000  (as  adjusted  pursuant  to Section
               415(d)  of the  Internal  Revenue  Code)  and was a member of the
               top-paid group for such year. The term 'highly compensated active
               employee'  also  includes an employee who is a '5-percent  owner'
               (within the  meaning of Section  414(q) of the  Internal  Revenue
               Code) any time  during the  look-back  year or the  determination
               year. An employee is in the  'top-paid  group' for a year if such
               employee  is in  the  group  consisting  of  the  top  20% of the
               employees  of all  Controlled  Group  Members  when ranked on the
               basis of compensation paid during such year.

               The  'determination   year'  shall  be  the  Plan  Year  and  the
               'look-back  year' shall be the  twelve-month  period  immediately
               preceding the determination  year. The calendar year which begins
               with or  within  the  look-back  year  shall  be  treated  as the
               look-back year for purposes of determining whether an employee is
               a  highly  compensated  employee  on  account  of the  employee's
               compensation  for a look-back year under Section  414(q)(1)(B) of
               the Internal Revenue Code.

                                      -3-

          (b)  A 'highly  compensated former employee' includes any employee who
               separated from service (or was deemed to have separated) prior to
               the determination year, performs no service for the Employer or a
               Controlled Group Member during the determination  year, and was a
               highly compensated active employee for either the separation year
               or any determination  year ending on or after the employee's 55th
               birthday.

          (c)  The  determination  of  who  is a  Highly  Compensated  Employee,
               including  the  determinations  of the  number  and  identity  of
               employees  in the  top-paid  group and the  compensation  that is
               considered,  shall be made in accordance  with Section  414(q) of
               the Internal Revenue Code and regulations thereunder.  The method
               of  determination  set forth above in this Section shall apply to
               all plans (both retirement and nonretirement) of the Employer for
               which  the  definition  of  'highly   compensated   employee'  is
               applicable."

     5.  Effective  as of  January 1, 1997,  Section  1.1(A)(32)  of the Plan is
amended to add the following paragraph at the end thereof:

          "Notwithstanding  the foregoing provisions of this Section 1.1(A)(32),
          each participant who is not a 5-percent owner, who has attained age 70
          1/2 in a  calendar  year  after 1995 and prior to 2002 and who has not
          retired by the end of such calendar year,  shall be entitled to elect,
          at the time and in the manner  specified by the Committee,  but in any
          event prior to April 1 of the  calendar  year  following  the calendar
          year in which  such  Participant  attained  age 70 1/2,  to defer such
          Participant's  Required  Beginning  Date until April 1 of the calendar
          year that next  follows the  calendar  year in which he retires.  Upon
          such election by the  Participant,  his Required  Beginning Date shall
          become April 1 of the calendar year immediately following the calendar
          year in which he retires.

          For purposes of this Section 1.1(A)(32), a Participant is treated as a
          5-percent  owner after  December 31, 1996,  if such  Participant  is a
          5-percent  owner,  as defined in Section 416 of the  Internal  Revenue
          Code,  with  respect to the Plan Year ending in the  calendar  year in
          which the Participant attains age 70 1/2."

     6.  Effective  as of  January 1, 2002,  Section  1.1(A)(32)  of the Plan is
amended to add the following paragraph at the end thereof:

          the  Required  Beginning  Date  for  each  Participant  who  is  not a
          5-percent  owner and who  attains  age 70 1/2 on or after  January  1,
<PAGE>

                                      -4-

          2002,  shall be April 1 of the calendar  year  following  the calendar
          year  in  which  such  Participant  attains  age 70  1/2  or  retires,
          whichever occurs later."

     7. Effective as of December 12, 1994,  the second  paragraph in Section 1.3
of the Plan is amended to add the following sentence at the end thereof:

          "Notwithstanding   any   provision  of  this  Plan  to  the  contrary,
          contributions,  benefits and service  credit with respect to qualified
          military service will be provided in accordance with section 414(u) of

     considered to be in the service of the Employer and shall not be considered
     to have incurred a termination  of his service until the date of his early,
     normal or disability  retirement,  death,  resignation,  discharge or other
     termination of his employment with an Employer, notwithstanding any payment
     or agreement to pay severance pay in connection with the termination of his
     employment."

     9.  Effective as of January 1, 1997,  Section 2.1(C) of the Plan is amended
to add the following paragraph at the end thereof:

          "Where a Participant's monthly retirement income commences after April
     1 following the calendar year in which such Participant attains age 70 1/2,
     the accrued benefit of such Participant  shall be actuarially  increased in
     accordance  with  regulations  or  other  official  pronouncements  of  the
     Internal Revenue Service to take into account the period beginning on April
     1 following the calendar year in which the  Participant  attains age 70 1/2
     and  ending on the date on which  benefits  under the Plan  commence  after
     retirement  in an amount  sufficient  to satisfy  Section  401(a)(9) of the
     Internal Revenue Code."

     10.  Effective  as of April 1, 1997,  Section  2.4(A)(2)(b)  of the Plan is

               writing filed with the Committee at least 30 but not more than 90
               days prior to the effective  date thereof (or if the  Participant
               waives  the  30-day  notice  period  with  any  required  spousal
               consent, then more than 7 days but not more than 90 days prior to
               the effective date thereof), the first day of any month, which is

     "3.2 - LUMP-SUM PAYMENT OF SMALL RETIREMENT INCOME
            -------------------------------------------

     single-sum  value of the  retirement  income or other  benefit  payable  on
     behalf  of any  Participant  hereunder  whose  retirement  income  or other
     benefit payments have not commenced does not exceed the maximum amount that
     is  permissible  as an  involuntary  cash-out  of  accrued  benefits  under
     Sections 411(a)(11) and 417(e) of the Internal Revenue Code and regulations
     issued with respect  thereto  ($5,000 as of April 1, 1998),  the  actuarial
     equivalent of such benefit shall be paid in a lump sum; provided,  however,
     that a lump-sum  distribution  under this Section 3.2 will not be permitted
     after the Annuity  Starting Date and will not be permitted in the case of a
     Participant  who  is  entitled  to  receive  disability  retirement  income
     payments."

     13.  Effective  as of  January 1, 2000,  Section  4.1(A)(1)  of the Plan is
amended to read in its entirety as follows:

          "(1) Maximum Amount of Retirement Income: Any provisions herein to the
     contrary  notwithstanding,  in no event shall the monthly retirement income
     that is payable on or after the first day of the limitation  year beginning
     in 1987 to a Participant  hereunder exceed the maximum amount of retirement
     income  for  defined  benefit  plans as  specified  in  Section  415 of the

     provided, however, that:

          (a)  the  maximum  amount  of  retirement   income   applicable  to  a
               Participant who was a participant in the Superseded Plan, if any,
               before the  limitation  year beginning in 1983 and whose Credited
               Service   includes   service  that  was  accrued  prior  to  such
<PAGE>

                                      -6-

               limitation  year,  shall  not be less  than his  current  accrued
               benefit within the meaning of Section 235(g)(4) of the Tax Equity
               and Fiscal Responsibility Act of 1982;

               and

          (b)  such  maximum  amount  of  retirement   income  applicable  to  a
               Participant who was a participant in the Superseded Plan, if any,
               before the  limitation  year beginning in 1987 and whose Credited
               Service   includes   service  that  was  accrued  prior  to  such
               limitation  year,  shall  not be less  than his  current  accrued
               benefit  within the meaning of Section  1106(i)(3)(B)  of the Tax
               Reform Act of 1986.

     In determining the maximum monthly  retirement  income payable on behalf of
     any  Participant,  all defined benefit plans (whether or not terminated) of
     the Controlled Group Members are to be treated as one defined benefit plan.
     The proportion of the maximum monthly  retirement  income applicable to all
     such  defined  benefit  plans  of the  Controlled  Group  Members  shall be
     determined on a pro rata basis  depending upon the  actuarially  equivalent
     amount of  retirement  income  otherwise  accrued  under each such  defined
     benefit plan."

     14.  Effective  as of  January 1, 1995,  Section  4.1(A)(2)  of the Plan is
amended to read in its entirety as follows:

          "(2)Actuarial Assumptions:  The mortality assumptions that are used to
     compute the  actuarially  equivalent  maximum  amount of retirement  income
     permitted  under this Section  4.1(A) on and after January 1, 1995 shall be
     based upon the  mortality  table  prescribed  by the  Secretary of Treasury
     pursuant to Section 415(b)(2)(E) of the Internal Revenue Code. The interest
     rate  assumptions  that  are used to  compute  the  actuarially  equivalent
     maximum amounts of retirement income permitted under the provisions of this
     Section  4.1(A)  shall  be the same as  those  that  are used in  computing
     actuarially equivalent benefits payable on behalf of a Participant upon his
     retirement  or  termination  of service  and upon the  exercise of optional
     forms of retirement income under the Plan except that:

          (a)  the interest  rate  assumption  shall not be less than 5% for the
               purposes of converting  the maximum  retirement  income to a form
               other than a straight life annuity (with no ancillary  benefits);
               provided,  however,  for the purposes of  converting  the maximum
               retirement  income to any form of  benefit  which is  subject  to
               Section  417(e)(3)  of the  Internal  Revenue  Code (which  shall
               include  lump-sum  distributions  and other forms of distribution
               that provide payments in the form of a decreasing annuity or that
               provide  payments  for  a  period  less  than  the  life  of  the
               recipient), such minimum interest rate assumption that applies on
               and after  January  1, 1995  shall (in lieu of 5%) be the  annual
<PAGE>

                                      -7-

               rate of interest on 30-year  Treasury  securities  for the second
               full calendar  month  immediately  preceding the first day of the
               Plan Year during which the Annuity Starting Date occurs;

          (b)  the interest rate assumption shall not be greater than 5% for the
               purposes of adjusting the maximum  retirement income payable to a
               Participant who is over the social security retirement age within
               the meaning of Section 415(b)(8) of the Internal Revenue Code (or
               age 65 in the case of a governmental plan or a plan maintained by
               a tax exempt  organization) so that it is actuarially  equivalent
               to such a retirement  income  commencing  at the social  security
               retirement age (or age 65 in the case of a governmental plan or a
               plan maintained by a tax exempt organization); and

          (c)  the factor  for  adjusting  the  maximum  permissible  retirement
               income to a Participant  who is less than age 62 years so that it
               is actuarially  equivalent to such a retirement income commencing
               at age 62 years shall be equal to (i) the factor for  determining
               actuarial equivalence for early retirement under the Plan or (ii)
               an actuarially  computed  reduction  factor  determined  using an
               interest  rate  assumption  of 5% and the  mortality  assumptions
               specified in the first sentence of this Section 4.1(A)(2) (except
               that the mortality  decrement shall be ignored if a death benefit
               at least  equal  to the  single-sum  value  of the  Participant's
               Accrued Deferred Monthly  Retirement  Income Commencing at Normal
               Retirement  Date would be payable under the Plan on behalf of the
               Participant if he remained in the service of the Employer and his
               service were to be terminated by reason of his death prior to his
               Normal  Retirement  Date),  whichever  factor  will  provide  the
               greater   reduction.   The  factor  for   determining   actuarial
               equivalence for early retirement under the Plan for any given age
               below age 62 years  shall be  determined  by  dividing  the early
               retirement  adjustment factor that applies under the Plan at such
               given age by the early retirement  adjustment factor that applies
               under the Plan at age 62 years."

     15.  Effective as of January 1, 1998,  Section  4.1(A)(4)(e) of the Plan is
amended to add the  following  sentence  between the second and third  sentences
thereof:

     "Notwithstanding  any  provisions of this  subsection to the contrary,  the

     defined in Section  402(g)(3) of the Internal  Revenue  Code,  and (ii) any

<PAGE>

     amount which is  contributed or deferred by the Employer at the election of
     the  Employee  and  which is not  includible  in the  gross  income  of the
     Employee by reason of Section 125 or Section  457 of the  Internal  Revenue
     Code."

     16. Effective as of January 1, 2000, Section 4.1(A)(4) is amended to delete

     the  term  'IRC 415  Compensation'  shall  also  include  (i) any  elective
     deferral as defined in Section  402(g)(3) of the Internal Revenue Code, and
     (ii) any amount  which is  contributed  or deferred by the  Employer at the
     election of the Employee and which is not includible in the gross income of
     the Employee by reason of Section 125, Section 132(f)(4), or Section 457 of

invested in accordance with Purchaser's direction and all interest earned on the
Earnest Money shall remain the property of and be paid to Purchaser. Wherever

Price in the amount thereof. If the transaction does not so close, the Earnest
Money shall be disbursed in accordance with the terms of this Agreement.

                  Provided that Purchaser does not terminate this Agreement nor

Seller, the interest theretofore earned on the Earnest Money shall be disbursed
to Purchaser, and Purchaser shall receive a credit at Closing against the
Purchase Price in the amount of the Earnest Money. In the event this Agreement

theretofore disbursed to Seller within two (2) business days after Seller's
receipt of such termination notice. Purchaser shall have the right to bring

party in such action shall be entitled to recover from the other the reasonable
attorneys' fees and litigation costs incurred by it in connection with such
matter. Any references in this Agreement to the return of Earnest Money to
Purchaser shall be deemed to include Seller's return of the Earnest Money in
accordance with the terms of this Section 3 if the Earnest Money has already
been disbursed to Seller. The terms of this Section 3 are not intended to
contradict the terms and conditions contained in Section 17 below.

            4.    CLOSING.

                  Subject to terms and conditions of this Agreement, the closing
of the transaction contemplated by this Agreement (the "Closing") shall take

Date") at the offices of the Title Company, or as the parties shall otherwise
agree. On the Closing Date, Seller shall transfer and convey title to the
Property to Purchaser free and clear of all liens and encumbrances, other than
real and personal property taxes not yet due and payable and such title
exceptions as may be permitted pursuant to

                                       3

<PAGE>

Section 6 below and in accordance with the Escrow. Notwithstanding the
foregoing, Purchaser shall have the right, upon written notice to Seller, to
accelerate the Closing Date to a date specified in such notice which is at least
five (5) business days after the date Seller receives such notice.

     5.   ESCROW.

          This transaction shall be closed through an escrow established with
Title Company in accordance with the deed and money escrow instructions in the
form attached hereto as Exhibit F (the "Escrow"). Upon the creation of the
Escrow, anything herein to the contrary notwithstanding, the transfer and
conveyance of the Property, the payment of funds and the delivery of the
Conveyance Documents (as defined below) and other documents required to close
the transaction contemplated by this Agreement shall be made through the Escrow.
All escrow costs shall be divided equally between Purchaser and Seller.

     6.   TITLE COMMITMENT.

          The parties acknowledge that Seller has provided Purchaser with a
current ALTA Form B title commitment (or such other comparable form as may be
reasonably acceptable to Purchaser and customary in the state where the Property
is located) (the "Title Commitment") for an owner's title insurance policy
issued by the title company identified in Line 10 of the Summary Statement (the
"Title Company"), covering title to the Land, Improvements and Appurtenant
Rights, together with legible copies of each of the documents underlying the
title exceptions listed therein.

          On or before the date that is ten (10) business days after Purchaser's
receipt of the Title Commitment and the Survey (defined below) (the "Objection
Date"), Purchaser will notify Seller in writing (the "Exception Notice") as to
those title exceptions listed in the Title Commitment which it will accept (the
"Permitted Exceptions"). If Purchaser fails to provide Seller the Exception
Notice on or before the Objection Date, the title exceptions listed in the Title
Commitment shall be deemed to be Permitted Exceptions and Purchaser shall be
deemed to have waived its right to object to such exceptions. Seller shall have
the right, but not the obligation, until the sooner of (x) the Closing Date, or
(y) the date which is ten (10) days after the date Seller receives the Exception
Notice (the soonest of which is hereinafter referred to as the "Title Clearance
Date") to have all title exceptions other than Permitted Exceptions
(collectively, the "Unpermitted Exceptions") removed from the Title Commitment
or to have Title Company commit to insure, at Seller's expense, against any and
all loss or damage that may be occasioned by any such Unpermitted Exceptions. If
Seller fails on or before the Title Clearance Date to reasonably demonstrate to
Purchaser that the Unpermitted Exceptions have been removed, or in the
alternative, that Seller has obtained a commitment for title indemnification or
title insurance over such Unpermitted Exceptions (provided such indemnification
or insurance shall be acceptable to Purchaser in its sole discretion), then, in
either such case, Purchaser shall, as its sole remedy, have the option (the
"Title Election") to either (i) terminate this Agreement, whereupon the parties
hereto shall have no further

                                       4

<PAGE>

obligations hereunder (except for obligations which are expressly intended to
survive the termination of this Agreement), and receive a return of the Earnest
Money, or 7. proceed with Closing, in which event the Purchase Price shall be
reduced by an amount equal to the aggregate amount of all tax, judgment and
mechanics' liens of a definite and ascertainable amount that constitute
Unpermitted Exceptions and Purchaser shall be deemed to have waived any
objection to any other Unpermitted Exceptions. If Purchaser fails to notify
Seller of its Title Election within five (5) days after the Title Clearance
Date, Purchaser shall be deemed to have elected to proceed with the Closing, as
set forth in subclause (ii) above.

               In the event the Title Company issues any modification or
supplement to the Title Commitment between the Objection Date and the Closing
Date that is not the result of activities of Purchaser or any of Purchaser's
agents, representatives, consultants or contractors and if, in Purchaser's
reasonable judgment, any such changes materially and adversely affect the
Property or Purchaser's projected use thereof, Purchaser shall have five (5)
business days after receipt of the modification or supplement to the Title
Commitment in which to object thereto by written notice to Seller, and such
objections shall be deemed to be Unpermitted Exceptions. Seller shall have five
(5) business days after receipt of Purchaser's objection notice (and, if
necessary, the Closing Date shall be extended by the number of days necessary to
give Seller this full five (5) business day period) in which to notify Purchaser
of its election to cure or not to cure Purchaser's objections in accordance with
the third grammatical sentence of the immediately preceding paragraph and the
terms and procedures set forth in such paragraph shall again be used to
determine the parties rights and obligations vis-a-vis such new Unpermitted
Exception(s).

          7.   SURVEY.

               Promptly after the date this Agreement becomes effective pursuant
to Section 22 below, Seller shall obtain, at Seller's expense, a survey of the
Land and Improvements (the "Survey"), dated on or after the date of this
Agreement and prepared by a land surveyor licensed by the state in which the
Land is located. The Survey shall be certified to Seller, Purchaser, the
Purchaser's lender (if any), and Title Company as having been prepared in
accordance with the 1997 minimum standard detail requirements for an Urban Land
Title Survey jointly adopted by the American Land Title Association and the
American Congress of Surveying and Mapping.

               On or before the Objection Date, Purchaser will notify Seller in
writing as to those encroachments, gaps, gores and other matters depicted on the
Survey which Purchaser shall not accept (the "Survey Defects"). If Purchaser
fails to provide Seller with written notice of any Survey Defects on or before
the Objection Date, Purchaser shall be deemed to have waived its right to object
to matters of survey (and to any related title exceptions raised on the Title
Commitment in connection with survey matters). Seller shall have the right, but
not the obligation, until the sooner of (x) the Closing Date, or (y) the date
which is ten (10) days after the date Seller receives notice of the Survey
Defects (the soonest of which is hereinafter referred to as the "Survey
Clearance Date") to have the Survey Defects removed from the Survey or to have
the Title Company commit to insure, at Seller's expense and subject to
Purchaser's approval in its sole discretion, against any and all loss or damage
that may be occasioned by any

                                       5

<PAGE>

such Survey Defect. If Seller fails on or before the Survey Clearance Date to
reasonably demonstrate to Purchaser that the Survey Defects have been removed,
or, in the alternative, that Seller has obtained a commitment for title
indemnification or title insurance over such Survey Defect, then, in either
case, Purchaser shall, as its sole remedy, have the option (the "Survey
Election") to either (i) terminate this Agreement, whereupon the Earnest Money
shall be returned to Purchaser and the parties hereto shall have no further
obligations hereunder (except for obligations which are expressly intended to
survive the termination of this Agreement), or (ii) proceed with Closing, in
which case Purchaser shall be deemed to have waived any objection to such Survey
Defects. If Purchaser fails to notify Seller of its Survey Election within ten
(10) days after the Survey Clearance Date, Purchaser shall be deemed to have
elected to proceed with the Closing as set forth in subclause (ii) above.

         8.    REPRESENTATIONS AND WARRANTIES.

               (a)   As used in this Section 8, references to "Seller's actual
         knowledge" shall mean the actual knowledge of Randal S. Bessolo, a
         managing director of Transwestern Investment Company, L.L.C., and of
         Jim Gilchrist, the property manager, after an investigation of Seller's
         files and records relating to the Property in its possession but
         without investigation or inquiry of any other person or entity. Seller
         represents that Messieurs Bessolo and Gilchrist have significant
         knowledge of the condition of the Property. Seller represents and
         warrants to Purchaser, as of the date hereof and again on the Closing
         Date, as follows:

                     (i)    As of the Closing Date, there shall be no Leases or
               Contracts granting any person or entity the right to possession
               or occupancy of the Land and/or Improvements; there shall be no
               persons in possession or occupancy of the Property, or any part
               thereof; nor shall there be, except to the extent such possessory
               right is granted through a Permitted Exception, any persons who
               have possessory rights with respect to the Property or any part
               thereof;

                     (ii)   As of the date of this Agreement, neither Seller
               nor, to Seller's actual knowledge, the Existing Tenant, is in
               default under the terms of the Sun Leases beyond expiration of
               notice and cure periods. As of the Closing Date, the Existing
               Tenant shall not be in default under the terms of the Sun Leases
               to the extent such default could affect title to or possession of
               any of the Property;

                     (iii)  During its period of ownership, Seller has received
               no written notice from any governmental authority of any
               violation of applicable laws, ordinances or regulations related
               to the Property or the occupancy thereof which have not been
               heretofore corrected, nor any written notice of increases in
               insurance premiums;

                     (iv)   Neither the execution or delivery of this Agreement,
               the consummation of the transaction contemplated hereby, nor the
               fulfillment of or compliance with the terms and conditions hereof
               conflict with or result in a material breach of any of the terms,
               conditions or provisions of any agreement or instrument to which
               the Seller is a party or by which Seller is bound;

                                       6

<PAGE>

                     (v)    There are no leasing commissions now or hereafter
               due with respect to any of the Leases for any current terms or
               exercised renewals, extensions or expansions. Seller has entered
               into no brokerage or leasing commission agreements with respect
               to the Property, where a commission or fee has been earned but
               not fully paid;

                     (vi)   There are no contracts or agreements affecting the
               operation of the Land or the Improvements (including without
               limitation management, maintenance, service, supply, purchase,
               consulting, advertising, promotion, public relations and
               construction contracts, agreements, commitments, guarantees and
               warranties) which will survive Closing and be binding upon
               Purchaser except as disclosed in Exhibit D attached hereto and,
               to Seller's actual knowledge, no party is in default under any
               such contracts. All Contracts, except those consented to in
               writing by the Purchaser, shall be terminated as of the Closing
               Date;

                     (vii)  To Seller's actual knowledge, there are no claims,
               causes of action, lawsuits or legal proceedings pending or
               threatened regarding the ownership, use or possession of the
               Property, including without limitation condemnation or similar
               proceedings except for the Pending Condemnation described below;

                     (viii) Seller is duly organized, validly existing and in
               good standing under the laws of the State of Delaware, and is
               qualified to do business under the laws of the jurisdiction where
               the Land is located. Seller has all necessary power and authority
               to enter into this Agreement and to consummate all of the
               transactions contemplated herein. The individuals executing this
               Agreement on behalf of Seller (or on behalf of members of Seller)
               are duly authorized to execute, deliver and perform this
               Agreement on behalf of Seller (or on behalf of members of Seller)
               and to bind Seller. This Agreement and all documents to be
               executed by Seller and delivered to Purchaser hereunder (A) are
               and will be the legal, valid and binding obligations of Seller,
               enforceable in accordance with their terms, (B) do not or will
               not contravene any provision of Seller's organizational documents
               or any existing laws and regulations applicable to Seller or the
               Property and (C) will not conflict with or result in a violation
               of any agreement, instrument, order, writ, judgment or decree to
               which Seller is a party or is subject or which governs the
               Property;

                     (ix)   Except as to matters disclosed in the environmental
               reports or other materials delivered by Seller to Purchaser: (A)
               Seller has not caused the generation, presence, use, release,
               transportation, storage, treatment or disposal at or from the
               Property of any Hazardous Substances (as defined in Section 21)
               in violation of any applicable environmental laws; (B) Seller has
               no actual knowledge of the generation, presence, use, release,
               transportation, storage, treatment or disposal at or from the
               Property of any Hazardous Substances in violation of any
               applicable environmental laws, (C) Seller has not received any
               written notice of any generation, transportation, storage,
               treatment or disposal at or from the Property of any Hazardous
               Substances in violation of any applicable environmental laws; and
               (D) no enforcement action or litigation has been brought

                                       7

<PAGE>

               or, to Seller's actual knowledge, threatened against Seller or
               the Property nor any settlements reached by Seller or, to
               Seller's actual knowledge, any prior owner of or other party
               having any interest in the Property, alleging the use of any
               Hazardous Substances on, from or under the Property in violation
               of any applicable environmental laws;

                     (x)   As of the Closing Date, there shall be no Lease
               (including but not limited to the Sun Leases) in effect;

                     (xi)  To Seller's actual knowledge, all approvals,
               easements and rights of way which are reasonably required by any
               and all governmental authorities having jurisdiction over the
               Property for the normal use, occupancy and operation of the
               Property have been obtained and all such approvals are in full
               force and effect; and

                     (xii) To Seller's actual knowledge, the Land and
               Improvements are connected to and serviced by adequate water,
               sewage disposal, gas, electricity and telephone facilities to
               meet the requirements of normal usage thereof.

         There is currently pending a condemnation proceeding ("Pending
         Condemnation") of a small strip of land containing approximately 3,444
         square feet of the Property ("Condemnation Parcel") in connection with
         a widening of Highway 880. Notwithstanding anything contained in this
         Agreement to the contrary, Seller shall be responsible for taking care
         of all matters associated with the Pending Condemnation including
         arranging for the deeding of the Condemnation Parcel to the condemning
         authority (or as it shall otherwise direct) and shall bear any and all
         costs associated therewith. Furthermore, Seller shall have the right to
         retain any and all payments from the condemning authority associated
         with the Condemnation Parcel whether or not they are paid prior to or
         after the Closing. Seller shall exercise due diligence to have all
         documentation completed and filed prior to or simultaneously with the
         Closing; provided, however, should Seller be unable to have all such
         documentation completed by such date, Purchaser covenants to cooperate
         with Seller and the condemning authority to effectuate same after the
         Closing including, but not limited to, execution of a deed, transfer
         declaration, etc.

               (b)   Purchaser represents and warrants to Seller, now and again
         on the Closing Date, that: (i) Purchaser has all necessary power and
         authority to enter into this Agreement and to consummate all the
         transactions contemplated herein, (ii) the individuals executing this
         Agreement on behalf of Purchaser are duly authorized to execute,
         deliver and perform this Agreement on behalf of Purchaser and to bind
         Purchaser and (iii) this Agreement and all documents to be executed by
         Purchaser and delivered to Seller hereunder (A) are and will be the
         legal, valid and binding obligations of Purchaser, enforceable in
         accordance with their terms, (B) do not or will not contravene any
         provision of Purchaser's organizational documents or any existing laws
         and regulations applicable to Purchaser and (C) will not conflict with
         or result in a violation of any agreement, instrument, order, writ,
         judgment or decree to which Purchaser is a party or is subject.

                                       8

<PAGE>

               (c)  All of the representations and warranties of Seller and
         Purchaser contained in this Section 8 are material, none shall merge
         into the deed herein provided for and all shall survive the Closing
         Date or termination of this Agreement for a period of twelve (12)
         months (the "Survival Period"). All rights of Purchaser hereunder with
         respect to any surviving representation, warranty or covenant shall be
         deemed waived if Purchaser does not, by written notice to Seller,
         advise Seller of any alleged breach of representation, warranty or
         covenant prior to the expiration of the Survival Period. Subject to the
         limitation set forth in the immediately preceding sentence, all
         remedies shall be those set forth in Section 17 below, and
         notwithstanding anything herein to the contrary, Seller's liability
         under any representation, warranty or covenant made hereunder or in any
         of the Closing Documents shall in no event exceed Seller's Maximum
         Liability (as hereinafter defined).

         9.    SELLER'S COVENANTS.

               From and after the date of this Agreement through the Closing
Date, Seller and Seller's agents shall at Seller's expense:

               (a)  maintain the Property in the condition in which it existed
         as of the date of this Agreement, normal wear and tear excepted, free
         from mechanics' liens and operate the Property in a manner consistent
         with current practice and perform its obligations under the Leases,
         Contracts and Licenses;

               (b)  keep in existence all fire and extended coverage insurance
         policies, and all public liability insurance policies, that are in
         existence as of the date of this Agreement with respect to the
         Property;

               (c)  not enter into or extend any Contract or License to a period
         beyond the Closing Date, nor apply any security or other deposits held
         under any License whose term shall extend beyond the Closing Date to
         delinquent payments, without Purchaser's prior written consent, which
         will not be unreasonably withheld. Notwithstanding the preceding
         sentence, (i) without the Purchaser's consent, the Seller shall have
         the right to enter into new contracts, licenses and leases, amend and
         extend leases, contracts and licenses, enforce and terminate leases,
         contracts and licenses, and apply security or other deposits provided
         the ramifications of such actions shall neither extend beyond the
         Closing Date nor be binding upon Purchaser;

               (d)  upon at least twenty-four (24) hours' notice to Seller,
         permit Purchaser, its engineer, architect or other agents, during
         normal business hours (or such other times as are reasonable), to enter
         onto the Land for the purpose of making inspections thereof;

               (e)  grant Purchaser access to any records, books and agreements
         concerning the Property within Seller's possession or control (with the
         exception of any such documents that Seller deems confidential or
         proprietary), and maintain such records, books and accounts in Seller's
         ordinary manner consistent with past practice;

                                       9

<PAGE>

               (f)  promptly advise Purchaser in writing of any changes in
         circumstances which would render the representations and warranties
         made by Seller herein false or misleading;

               (g)  upon written notice from Purchaser or before the Approval
         Date, give appropriate notices of termination of Contracts designated
         by
         Purchaser; provided, however, that if the notice period required to
         terminate such contracts will not have run prior to Closing, Seller
         shall be obligated to bear the cost of any remaining obligations under
         such Contracts accruing after the Closing Date;

               (h)  not enter into any financing agreement which would encumber
         the Property beyond the Closing Date nor perform any new construction
         work on the Property which (a) will not be fully paid for by the
         Closing Date or (b) is not reasonably necessary to comply with the
         terms of this Agreement or any agreement by which Seller or the
         Property is bound except to the extent same is reasonably necessary for
         health or safety reasons. Notwithstanding anything contained in this
         Agreement to the contrary, Seller shall have the right to enter into
         the Temporary Construction Easement with the City of Milpitas, a copy
         of which has been previously delivered to Seller;

               (i)  after the Approval Date, not accept any offers from other
         potential purchasers of the Property or market the Property to
         potential purchasers of the Property;

               (j) not extend the term of the Sun Leases without Purchaser's
         prior written consent;

               (k)  exercise commercially reasonable efforts to ensure that no
         contracts, licenses or other agreements entered into by or on behalf of
         the Existing Tenant which affect the Property extend beyond the Closing
         Date;

               (l)  from and after June 30, 2002, use commercially reasonable
         efforts to enforce the terms of the Sun Leases, including the
         obligation of the Existing Tenant to surrender the Property in
         accordance with the terms of the Sun Leases; and

               (m)  provide Purchaser with any other relevant information with
         respect to the Property upon Purchaser's reasonable request.

         10.   APPROVAL DATE.

               (a)  Purchaser shall have from the date this Agreement becomes
         effective pursuant to Section 22 below through the Approval Date
         identified in Line 8 of the Summary Statement (the "Approval Date") to
         inspect the Property and complete such tests, inspections and
         investigations as Purchaser may determine in its sole discretion. The
         period between the date this Agreement becomes effective and the
         Approval Date is called the "Inspection Period." Without limiting the
         generality of the first sentence of this Section 10(a), during the
         Inspection Period: (A) Seller shall permit Purchaser to examine, at all
         reasonable times, all books and records (including without limitation
         financial and operating statements) in Seller's possession or control
         relating to the Property, (B) Purchaser shall have the right, at all
         reasonable times, to (I) inspect the Land,

                                       10

<PAGE>

         Improvements, Appurtenant Rights and Personal Property, (II) review the
         Leases, the Contracts, the Licenses and the Intangibles, (III) discuss
         the Property with, and obtain additional information from, tenants and
         any property manager and (IV) conduct geophysical feasibility tests of
         the Property and environmental audit or audits of the Property (with
         copies of the reports relating to such audits delivered to Seller when
         completed), including sampling, and (C) Purchaser shall be given
         complete access to the Property for the purpose of making such tests,
         inspections and investigations. All of the foregoing tests,
         investigations and studies to be conducted under this Section 10(a) by
         Purchaser shall be subject to the following:

                         (i)   Such tests, inspections and investigations shall
                  take place during normal business hours upon reasonable notice
                  to Seller or its designated agents and Seller's consent shall
                  be required prior to the performance of any drilling, boring
                  or other invasive testing or procedures;

                         (ii)  In the event the Closing does not occur,
                  Purchaser shall promptly return to Seller any documents
                  obtained from Seller or Seller's agents;

                         (iii) Purchaser shall not suffer or permit any lien,
                  claim or charge of any kind whatsoever to attach to the
                  Property or any part thereof; and

                         (iv)  such tests, investigations and studies shall be
                  at Purchaser's sole cost and expense and shall not
                  unreasonably interfere with the operation of the Property. In
                  the event of any damage to the Property caused by Purchaser,
                  its agents, engineers, employees, contractors or surveyors
                  (including, without limitation, pavement, landscaping and
                  surface damage), Purchaser shall pay the cost incurred by
                  Seller to restore the Property to the condition existing prior
                  to the performance of such tests, investigations or studies.

                  Purchaser shall defend, indemnify and hold Seller harmless
         from any and all liability, cost and expense (including without
         limitation, reasonable attorneys' fees, court costs and costs of
         appeal) suffered or incurred by Seller for injury to persons or
         property caused by Purchaser's investigations, tests, studies and
         inspections of the Property. Prior to commencing any such tests,
         studies and investigations, Purchaser shall furnish to Seller a
         certificate of insurance evidencing comprehensive general public
         liability insurance insuring the person, firm or entity performing such
         tests, studies and investigations and listing Seller and Purchaser as
         additional insureds thereunder. If, in the sole discretion and at the
         sole election of Purchaser, any of said tests, inspections or
         investigations are unsatisfactory to Purchaser, in any manner or for
         any reason in Purchaser's sole discretion, including without limitation
         for reasons relating to restrictions on use of the Property, matters
         relating to zoning, government approvals, title, survey, appraised
         value or other matters impacting the condition or value of the
         Property, Purchaser may terminate this Agreement. If Purchaser notifies
         Seller, in writing, on or before 5:00 p.m. (San Francisco time) on the
         Approval Date of Purchaser's election to proceed under this Agreement,
         then this Agreement shall remain in full force and effect and Purchaser
         shall deposit the Additional Earnest Money as required by Section 3
         hereof. If Purchaser fails to notify Seller, in writing, on or before
         5:00 p.m. (San Francisco time) on

                                       11

         the Approval Date of Purchaser's election to proceed or if Purchaser
         notifies Seller in writing of Purchaser's election to terminate this
         Agreement on or before the Approval Date, this Agreement shall
         terminate, the Earnest Money and all interest earned thereon shall be
         delivered to Purchaser and the parties hereto shall have no further
         obligations hereunder (except for obligations which are expressly
         intended to survive termination of this Agreement).

               (b)  The obligation of Purchaser to close the transaction
         contemplated by this Agreement is further subject to the condition
         that: (i) all of the representations and warranties of Seller contained
         in this Agreement are true and correct, in all material respects, at
         the date hereof and as of the Closing Date, and (ii) all of the
         obligations and duties of Seller to be performed hereunder on or before
         the Closing Date have been substantially completed in a timely manner.
         Purchaser shall give written notice to Seller within five (5) days
         after Purchaser's receipt of any written notice disclosing that any
         Seller representation and warranty is no longer true and correct;
         provided, however, that Purchaser's failure to give such written notice
         shall in no instance constitute a default by Purchaser under this
         Agreement but shall instead only serve to bar Purchaser from raising
         such matter as a failure of a condition precedent to Purchaser's
         obligation to close the transaction and Purchaser's election to proceed
         with the Closing shall result in Purchaser's waiver of any remedy
         resulting from the incorrectness in such representation of warranty.

               (c)  All information, data and documents relating to the Property
         (including, without limitation, those furnished pursuant to the terms
         and provisions of Section 9(h)), obtained by Purchaser from Seller or
         any other party or discovered by Purchaser during the term of this
         Agreement shall be maintained by Purchaser in strict confidence and may
         not be revealed to any other party except that Purchaser may make such
         disclosures as may be required by applicable laws and to its employees,
         managers, members, officers, lenders, attorneys, contractors
         accountants, appraisers, insurance advisors, consultants and similar
         third party professionals provided such party agrees to maintain such
         information in strict confidence and not reveal any such information to
         any other party.

         11.   DELIVERY OF DOCUMENTS.

               (a)  During the Inspection Period, Seller shall provide Purchaser

                  tenants and mortgagees with respect to the Property that are
                  in Seller's possession or control, all other documents
                  material to the condition, maintenance or operation of the
                  Property; and

                         (viii) all other documents relating to the Property
                  as Purchaser shall reasonably request in writing within
                  fifteen (15) days after the date this Agreement has been fully
                  executed by the parties.

         In the event Seller is unable to locate or obtain copies of "as built"
         architectural and engineering plans and specifications for the
         improvements currently existing on the Property prior to Closing,
         Seller shall provide Purchaser with a credit at Closing in an amount
         not to exceed the sum of $30,000 to cover the cost of obtaining same.
         The parties acknowledge and agree that they shall cooperate in
         obtaining bids for such drawings and shall agree upon the actual amount
         of the credit (not to exceed $30,000 in any event) prior to the
         Approval Date.

                  (b)    On the Closing Date, Seller shall deliver the following
         documents (the "Closing Documents") to Purchaser, all duly executed,
         where appropriate, each of which shall be a condition precedent to
         Purchaser's obligation to close the transaction contemplated by this
         Agreement (and one or more of which may be waived in writing by the
         Purchaser, in its sole discretion, on or prior to the Closing Date):

                  Improvements and Appurtenant Rights to Purchaser;

                         (ii)   a bill of sale, in the form of Exhibit G-2

                  Personal Property to Purchaser;

                         (iii)  an assignment and assumption, in the form of
                  Exhibit G-3 attached hereto, executed by Seller, that
                  transfers all of Seller's right, title and interest in and to
                  the Contracts, the Licenses, and the Intangibles to Purchaser

                  transfer declarations described above;

                                       14

<PAGE>

                         (ii)   counterparts of the Assignment and Assumption,
                  executed by Purchaser;

                         (iii)  counterparts of the closing and proration

                         (iv)   a certified copy of the resolutions or consent

                  agent, in order to issue the Title Policy free of any
                  exceptions raised due to the actions of Purchaser, and to
                  otherwise consummate the Closing.

            12.   FIRE OR CASUALTY.

                  In the event of damage to the Property by fire or other
casualty prior to the Closing Date, Seller shall promptly notify Purchaser of
such fire or other casualty. If the fire or other casualty causes damage which
would cost in excess of $500,000 to repair (as determined by Seller in good
faith), then Purchaser may elect, by written notice to be delivered to Seller on
or before the twentieth (20th) day after Purchaser's receipt of such notice (and
the Closing Date shall be extended, if necessary, to accommodate such twenty
(20) day period), to either: (a) close the transaction contemplated by this
Agreement and receive all insurance claims and proceeds payable to Seller as a
result of such fire or other casualty, with the same being paid or assigned to
Purchaser at Closing (and Seller shall pay the insurance deductible or give
Purchaser a credit therefor) or (b) terminate this Agreement, and receive a
return of the Earnest Money in which case the parties hereto shall have no
further obligations hereunder (except for obligations which are expressly
intended to survive the termination of this Agreement). If the damage to the
Property by fire or other casualty prior to the Closing Date would cost less
than or equal to $500,000 to repair (as determined by Seller in good faith),
Purchaser shall not have the right to terminate its obligations under this
Agreement by reason thereof, and Seller shall have the right to elect to either
repair and restore the Property if such repair or restoration may be completed
prior to the Closing Date or to assign and transfer to Purchaser on the Closing
Date all of Seller's right, title and interest in and to all insurance proceeds
paid or payable to Seller on account of such fire or casualty (and Seller shall
pay the insurance deductible or give Purchaser a credit therefor). The
provisions of this Section 12 shall survive the termination of this Agreement.

                                       15

<PAGE>

           13.    CONDEMNATION.

                  If, prior to the Closing Date, all or any part of the Property
is taken by condemnation or a conveyance in lieu thereof, or if notice of a
condemnation proceeding with respect to the Property is received by Seller (a
copy of which notice shall be immediately delivered by Seller to Purchaser),
Seller shall promptly notify Purchaser of such condemnation or a conveyance in
lieu thereof. If the taking or threatened taking involves a material portion of
the Property (hereinafter defined), Purchaser may elect, by written notice to be
delivered to Seller on or before the twentieth (20th) day after Purchaser's
receipt of such notice (and the Closing Date shall be extended, if necessary, to
accommodate such twenty (20) day period), to terminate this Agreement, in which
event the Earnest Money shall be returned to Purchaser, and the parties hereto
shall have no further obligations hereunder (except for obligations which are
expressly intended to survive the termination of this Agreement). If Purchaser
elects to close this transaction notwithstanding such taking or condemnation,
Purchaser shall be entitled to any award given to Seller as a result of such
condemnation proceedings, with the same being paid or assigned to Purchaser at
Closing. As used herein, a "material portion of the Property" means any part of
the Property reasonably required for the operation of the Property in the manner
operated on the date hereof. If any taking or threatened taking does not involve
a material portion of the Property, Purchaser shall be required to proceed with
the Closing, in which event Seller shall assign to Purchaser any award given to
Seller as a result of such condemnation proceedings. The parties acknowledge and
agree that the Pending Condemnation and the Condemnation Parcel shall be deemed
not to involve a material portion of the Property. The provisions of this
Section 13 shall survive the termination of this Agreement.

           14.    ADJUSTMENTS AND PRORATIONS.

                  Adjustments and prorations with respect to the Property shall
be computed and determined between the parties as of 12:01 a.m. on the Closing
Date as follows:

                  (a)    General real estate taxes, special assessments and
           personal property taxes shall be prorated as of the Closing Date
           based on the then current taxes (if known, based on final tax bills
           for such period -- and if not known, based on the most recent
           ascertainable taxes) and the special assessments due and owing prior
           to Closing, and Seller or Purchaser shall receive a credit at
           Closing, as appropriate. If final taxes or special assessments are
           not known as of the Closing, the parties agree to reprorate when such
           amounts become known, but no later than ninety (90) days after
           issuance of the final tax bill.

                  (b)    Seller shall have the right to contact tenants to
           reconcile CAM, taxes and other pass-throughs and additional rent with
           respect to the Property including delinquent rentals after the
           Closing Date and institute legal proceedings to collect such amounts,
           if necessary. Any such enforcement or collection efforts by Seller
           shall be at Seller's sole expense.

                                       16

<PAGE>

              (c)    All amounts payable, owing or incurred in connection with
         the Property under the Contracts to be assumed by Purchaser under the
         Assignment and Assumption shall be prorated as of the Closing Date.

              (d)    All utility deposits, if any, may be withdrawn by and
         refunded to Seller and Purchaser shall make its own replacement
         deposits for utilities as may be required by the respective utilities
         involved.

              (e)    The Earnest Money (unless previously disbursed to Seller)
         shall be paid to Seller at Closing. Purchaser shall be entitled to a
         credit against the Purchase Price in the amount of the Earnest Money
         paid to Seller or credited against the Purchase Price, as the case may
         be.

              (f)    All utility charges will be prorated to the Closing Date
         and Seller will obtain a final billing therefor and pay any amounts
         owing therein for the period prior to the Closing Date and Purchaser
         shall pay any amounts owing for the period on and after the Closing
         Date. To the extent that utility bills cannot be handled in the
         foregoing manner, they shall be prorated as of the Closing Date based
         on the most recent bills available and reprorated when such final bills
         become known but no later than ninety (90) days after the Closing Date.

              (g)    A credit, if applicable, in accordance with Section 11(a)
         above.

              (h)    Unless provided otherwise hereinabove, such other items as
         are customarily prorated in a purchase and sale of the type
         contemplated hereunder shall be prorated as of the Closing Date.

              (i)    Each of the provisions of this Section 14 shall survive the
         Closing.

         15.  CLOSING COSTS.

              Seller shall pay: (a) the costs of recording any releases required
to clear title to the Property, (b) the costs of the Survey, (c) the cost of
state or county stamp tax, sales tax, documentary transfer tax or other tax
imposed on the transfer of the Property, (d) Seller's attorneys' fees, and (e)
one-half of all escrow and New York Style closing fees. Purchaser shall pay: (i)
the costs of recording the deed, (ii) the costs of the Title Commitment and the
Title Policy, including any endorsements or deletions thereto, (iii) Purchaser's
attorneys' fees, and (iv) one-half of all escrow and closing fees.

         16.  POSSESSION.

              Possession of the Property shall be delivered to Purchaser at
Closing, free and clear of all liens and claims other than Permitted Exceptions,
in the same condition as it exists on the date of this Agreement, ordinary wear
and tear excepted and except as provided in Sections 12 and 13 hereof. The
Existing Tenant is the sole tenant of the Property. The Sun Leases are scheduled
to expire on June 30, 2002 and the Closing shall be contingent upon the

                                       17

<PAGE>

Existing Tenant having vacated the Property substantially in accordance with the
terms of the Sun Leases prior to Closing; provided, however, the parties agree
that the date of the Closing shall be delayed in accordance with Line 9 of the
Summary Statement until such time as the Existing Tenant shall have vacated the
Property. In the event the transaction contemplated by this Agreement fails to
close on or before August 1, 2002 due solely to the fact that the Existing
Tenant has not vacated the Property substantially in accordance with the terms
of the Sun Leases, then Purchaser shall receive as a credit at Closing an amount
equal to interest calculated at the Imputed Interest Rate (defined below) on the
amount of the Earnest Money theretofore paid to Seller from August 1, 2002
through the date of Closing. For purposes hereof, the Imputed Interest Rate
shall be a per annum rate of interest equal to the rate of interest Escrow Agent
was paying on the Earnest Money as of the Approval Date ("Imputed Interest
Rate"). Purchaser shall have the right to inspect the Property within three (3)
days prior to Closing to verify that the condition of the Property is as
required under this Agreement. Subject to the terms of the Sun Leases, Seller
shall exercise reasonable efforts to afford Purchaser reasonable access to the
Improvements for purposes of inspecting and/or measuring the premises, it being
understood and agreed that Purchaser shall not have the right to perform any
construction or demolition work in or about any portion of the Property prior to
the Closing Date.

              The Generator was installed by the Existing Tenant who may or may
not be obligated to remove it from the Property pursuant to the Sun Leases.
Seller covenants that it shall exercise reasonable efforts to cause the Existing
Tenant to leave the Generator at the Property and to relinquish any and all
right and title it may have thereto (and, to the extent feasible, to transfer
title to the Generator directly to Purchaser); provided, however, Seller shall
not be obligated to incur any expense or obligation or relinquish any rights it
may have against the Existing Tenant (except the obligation of the Existing
Tenant to remove the Generator) in order to effectuate same. As consideration
for allowing the Existing Tenant to possibly leave the Generator at the
Property, Seller shall have the right to require that the Existing Tenant agree
to remove the Generator from the Property in the event this Agreement is
terminated or the transaction contemplated hereby does not close for any reason.
Seller shall exercise reasonable efforts to resolve this issue prior to the
Approval Date; provided, however, it shall not be a condition of this Agreement
that the Generator remain at the Property. Purchaser acknowledges that (1) as of
the date of this Agreement, Seller may not have title or any rights to the
Generator, (2) if Seller fails to obtain title thereto, all references to
"Property" in this Agreement shall specifically exclude the Generator, and (3)
notwithstanding anything contained in this Agreement to the contrary, Seller is
making no representations or warranties with respect to title to or the
condition of the Generator and all representations contained in the Agreement
(including, but not limited to, those contained in Section 8) hereby
specifically exclude the Generator.

         17.  DEFAULT.

              If Seller defaults hereunder and fails to cure such default within
five (5) days after written notice of such default, or if the representations
and warranties set forth in this Agreement shall not be true and correct in all
material respects on the date of this Agreement and as of the Closing Date,
Purchaser's sole remedy shall be to either (a) terminate this Agreement and

                                       18

<PAGE>

receive a return of the Earnest Money, in which event each of the parties hereto
shall be relieved of any further obligation to the other arising by virtue of
this Agreement (except for obligations which are expressly intended to survive
the termination of this Agreement), or (b) pursue specific performance of this
Agreement. In no event shall Seller be liable for any actual, special, punitive,
speculative or consequential damages, nor shall Seller's liability under any
representation, warranty, covenant, agreement, proration, reproration,
obligation or indemnity made hereunder or under any of the Closing Documents
exceed $1,500,000 in the aggregate (the "Seller's Maximum Liability"). In the
case of (a) above, Seller shall reimburse Purchaser for all actual,
out-of-pocket costs, consisting of due diligence negotiation costs and costs of
negotiating this Agreement, including reasonable attorneys' fees, but in no
event shall Seller be liable for more than $75,000 for Purchaser's out-of-pocket
expenses in the aggregate. None of Seller's partners, members, managers,
officers, agents or employees shall have any personal liability of any kind or
nature or by reason of any matter or thing whatsoever under, in connection with,
arising out of or in any way related to this Agreement and the transactions
contemplated herein, and Purchaser waives for itself and for anyone who may
claim by, through or under Purchaser any and all rights to sue or recover on
account of any such alleged personal liability. If Purchaser defaults hereunder
and fails to cure such default within five (5) days of written notice of such
default, this Agreement shall terminate and Seller shall retain or receive the
Earnest Money if the Earnest Money is still held in Escrow as liquidated damages
in full settlement of all claims against Purchaser (with the exception of claims
against Purchaser related to obligations which are expressly intended to survive
the termination of this Agreement). The parties agree that the amount of actual
damages which Seller would suffer as a result of Purchaser's default would be
extremely difficult to determine and have agreed, after specific negotiation,
that the amount of the Earnest Money is a reasonable estimate of Seller's
damages and is intended to constitute a fixed amount of liquidated damages in
lieu of other remedies available to Seller and is not intended to constitute a
penalty. RETENTION OF THE EARNEST MONEY BY SELLER IS INTENDED TO CONSTITUTE
LIQUIDATED DAMAGES TO SELLER PURSUANT TO SECTIONS 1671, 1676 AND 1677 OF THE
CALIFORNIA CIVIL CODE AND SHALL NOT BE DEEMED TO CONSTITUTE A FORFEITURE OR
PENALTY WITHIN THE MEANING OF SECTION 3275 OR SECTION 3369 OF THE CALIFORNIA
CIVIL CODE, OR ANY SIMILAR PROVISION.

              PURCHASER AND SELLER ACKNOWLEDGE THAT THEY HAVE READ AND
UNDERSTAND THE PROVISIONS OF THIS SECTION 17 AND BY THEIR INITIALS IMMEDIATELY
BELOW AGREE TO BE BOUND BY ITS TERMS.

amount of one and three quarters percent (1.75%) of the Purchase Price out of

and expenses (collectively, "Leasing Costs") that are due and payable as of the
Closing Date with respect to Leases in force as of or prior to Closing. On the

unless expressly assumed by Purchaser in writing, any current management or
leasing agreements for the Property have been terminated (or notice of
termination given), and that the manager and any brokers have been paid all
commissions or fees due and payable. Purchaser is not required to continue the
employment of any employees of Seller or any property manager after the Closing
Date. Seller shall satisfy all obligations to all employees, if any, employed by
Seller or otherwise in the operation of the Property and provide Purchaser with
evidence thereof satisfactory to Purchaser on the Closing Date.

         of this Agreement.

              (i)  This Agreement shall not be construed more strictly against

         contributed substantially and materially to the preparation of this

         amendment hereto or any notice delivered hereunder shall have the same
         legal effect as an original signature.

              (n)  Prior to the Closing Date, the parties shall keep the terms
         of this Agreement confidential and shall not disclose such terms to any
         other parties without the other party's prior written consent, which
         consent shall be in each party's sole discretion; provided, however,
         that each party may, without obtaining such prior written consent, make
         such disclosures as may be required by applicable laws or agreements by

         officers, lenders, employees, attorneys, accountants, appraisers,
