fail to deliver the Feasibility Deposit to Escrow Holder before the end of the
Feasibility Period, then Buyer shall be deemed to have elected not to acquire
the Property and to have terminated this Agreement in accordance with Section
4.4 hereof, and the provisions of Section 17 shall govern the rights and
obligations of the parties thereafter.

                  3.1.3. ESCROW HOLDER ACKNOWLEDGMENT. Escrow Holder agrees to
deliver, or cause to be delivered, to Buyer and Seller, Escrow Holder's written
acknowledgment promptly after Escrow Holder shall have received each of the
following (a) a fully executed copy of this Agreement, (b) the Initial Deposit,
or (c) the Feasibility Deposit.

            3.2.  INVESTMENT OF EARNEST MONEY. Escrow Holder shall, promptly
upon receipt, deposit the Earnest Money in an interest-bearing account at a
financial institution selected by Buyer and approved by Seller. The interest
thus derived shall become part of the Earnest Money and shall be paid to the
party entitled to the Earnest Money in accordance with



                                       4
<PAGE>

the terms hereof. Buyer and Seller agree to and shall be bound by the terms set
forth on EXHIBIT "D" attached hereto.

            3.3.  DISBURSEMENTS OF EARNEST MONEY TO SELLER. At Seller's sole
election, upon receipt of the Feasibility Deposit, Escrow Holder shall disburse
all of the Earnest Money to Seller. In the event Seller so elects, the
affirmative act of Buyer's delivery of the Feasibility Deposit into Escrow shall
constitute Buyer's instructions to Escrow Holder to effect the disbursements to
Seller described in this Section. The foregoing disbursements of the Earnest
Money constitute a material part of this agreement between Buyer and Seller,
and, except as otherwise provided herein, are unrelated to any event of default
or damage. Buyer and Seller recognize that the Escrow will not have closed and
that documents will not have been recorded at the time of such release; if
Seller so elects, Buyer and Seller nevertheless hereby instruct Escrow Holder to
release the foregoing sums to Seller as herein provided and agree to indemnify
and hold harmless Escrow Holder in connection therewith. Seller shall have no
obligation to segregate the Earnest Money (to the extent in Seller's possession)
from Seller's other funds or invest the Earnest Money. Once delivered to Seller,
the Earnest Money shall not accrue interest.

            3.4.  APPLICATION OF EARNEST MONEY. If the sale hereunder is
consummated in accordance with the terms hereof, the Earnest Money shall be
applied toward the Purchase Price to be paid by Buyer at the Closing. In the
event of a default hereunder by Seller, the Earnest Money shall be refunded to
Buyer as set forth in Section 16.1. In the event of a default hereunder by
Buyer, the Earnest Money shall be disbursed to or retained by Seller, as
liquidated damages, as set forth in Section 16.2. If this Agreement shall
terminate in accordance with its terms other than as a consequence of a default
hereunder by Buyer or Seller, the Earnest Money shall be applied as set forth in
Section 17.

            3.5.  NON-REFUNDABILITY. Buyer acknowledges that Seller will incur
significant carrying costs and that Seller may suffer significant opportunity
costs if this Agreement terminates before the Closing. From and after the date
when Buyer shall have delivered the Initial Deposit and the Feasibility Deposit,
respectively, to Seller, the Earnest Money shall be completely non-refundable,
except as provided in Sections 16.1 and 17.

      4.    FEASIBILITY.

            4.1.  BUYER'S FEASIBILITY ANALYSIS. The parties have established the
Feasibility Period under this Agreement in order to provide Buyer with a limited
but appropriate and reasonable period of time to fully and independently assess
the Property, its condition, its value, its marketability, its past and present
uses and activities (including any such use or activity bearing upon liability
of owner or operators under environmental laws), its habitability, its
feasibility for use and development, the attributes and viability of the
existing permits for the Property and the Seller Diligence Deliveries, the
effect of all permits, approvals, laws, statutes, rules, ordinances and other
governmental regulations or requirements applicable to any of the foregoing
(including but not limited to the PID Permit, the Vesting Tentative Map and
permits and approvals required with respect to zoning, planning, building and
safety, fire, police, handicapped access, transportation, parking and
environmental matters), and any and all other matters pertinent to Buyer's
acquisition, ownership, use or development of the Property. The



                                       5
<PAGE>

foregoing analysis sometimes is referred to herein as the "BUYER'S FEASIBILITY
ANALYSIS". The length of the Feasibility Period has been calculated to balance
Seller's legitimate interest in expeditiously obtaining a final decision from
Buyer as to its decision to proceed with the acquisition of the Property against
Buyer's legitimate need for an adequate period to complete the Buyer's
Feasibility Analysis, and Buyer acknowledges and agrees that the Feasibility
Period will be adequate and sufficient for this purpose.

            4.2.  DILIGENCE DELIVERIES. If not already delivered, within two (2)
Business Days after the Effective Date, Seller shall deliver the materials
listed on EXHIBIT "E" attached hereto (the "SELLER DILIGENCE DELIVERIES") to
Buyer. Buyer shall be responsible for gathering any and all other information
which Buyer might deem pertinent to its acquisition of the Property, including
but not limited to confirmation of the acreage and PID square footage
approximations.

            4.3.  INSPECTION AND INDEMNITY. During the Feasibility Period, Buyer
shall fully and independently inspect and assess the condition of the Property,
the Seller Diligence Deliveries, and any other information deemed pertinent by
Buyer to its acquisition, use or development of the Property (including any
permits, approvals, laws, statutes, rules, ordinances and other governmental
regulations or requirements applicable to the Property), and to approve or
disapprove the same in its sole discretion. In connection therewith, Buyer shall
have the right physically to inspect, and to cause one or more engineers or
other representatives of Buyer physically to inspect, the Property without
interfering with Seller's operation of the Property. Buyer shall make such
inspections in good faith and with due diligence. All inspection fees, appraisal
fees, engineering fees and other expenses of any kind incurred by Buyer relating
to the inspection of the Property will be solely Buyer's expense. Seller shall
cooperate reasonably with Buyer in providing access to the Property for such
inspections. Seller hereby reserves the right to have a representative present
when Buyer conducts any inspection of the Property. Prior to and as a condition
to Buyer making each physical inspection of the Property, Buyer shall provide
Seller with all of the following items reasonably in advance of such inspection
(but in any case at least three (3) Business Days before such inspection): (a)
reasonably detailed written notice of the proposed date, time and nature of such
inspection, (b) evidence in a form reasonably acceptable to Seller that Buyer
has obtained and will maintain in force and effect insurance that is, in
Seller's judgment, appropriate to cover any risks related to such inspection,
and (c) evidence in a form reasonably acceptable to Seller that Buyer has
obtained all permits or other governmental approvals required for such
inspection. In making any inspection, Buyer shall treat, and shall use best
efforts to cause any representative of Buyer to treat, all information obtained
by Buyer pursuant to the terms of this Agreement as strictly confidential. Buyer
shall indemnify, protect, defend (with counsel approved by Seller) and hold
harmless Seller, its affiliates, its contractors and its employees from and
against any and all injuries, losses, liens, claims, judgments, liabilities,
costs, expenses and damages (including reasonable attorneys' fees and court
costs) sustained by or threatened against Seller which result from or arise out
of any inspections of the Property by Buyer or its representatives (except to
the extent caused by Seller's gross negligence or willful misconduct).
Notwithstanding any provision herein to the contrary, the indemnity contained in
the preceding sentence shall survive the Closing or the earlier termination of
this Agreement for a period of two (2) years. After the expiration of the



                                       6
<PAGE>

Feasibility Period, Buyer may continue to inspect the Property during the
pendency of this Agreement but without additional termination rights.

            4.4.  BUYER'S TERMINATION. In the event Buyer determines, as a
result of the foregoing, that Buyer, in Buyer's sole and absolute discretion,
elects not to acquire the Property, then Buyer shall terminate this Agreement by
delivering written notice thereof to Seller and Escrow Holder before the
expiration of the Feasibility Period and the provisions of Section 17 shall
govern the rights and obligations of the parties thereafter.

      5.    CONDITION OF TITLE.

            5.1.  PRELIMINARY TITLE REPORT. No later than five (5) Business Days
after the Effective Date, Seller shall, or shall cause Title Company to, deliver
to Buyer (i) a preliminary title report (the "TITLE REPORT") on the Property
issued by Title Company; (ii) copies of all documents shown as exceptions in the
Title Report; (iii) a copy of the most recent tax bill for the Property; and
(iv) per Buyer's request, title insurance commitment (which, in the event of
termination of this Agreement for any reason, including a failure to close,
shall be charged solely to Buyer by Title Company). If Buyer desires to obtain,
at Buyer's sole expense, an American Land Title Association ("ALTA") Extended
Coverage Owner's Policy of Title Insurance in lieu of a California Land Title
Association ("CLTA") Owner's Title Insurance Policy, then within ten (10)
Business Days after Buyer shall have received the Title Report and copies of all
documents shown therein as exceptions to title (but in all events prior to
expiration of the Feasibility Period), Buyer shall notify Seller thereof. If any
exceptions appear in the Title Report that are unacceptable to Buyer, then Buyer
shall, before the expiration of such ten (10) Business Day period (but in all
events prior to expiration of the Feasibility Period), provide written notice to
Seller, which notice shall specify all such unacceptable exceptions to title
(collectively, "BUYER'S TITLE OBJECTIONS") and describe why each such title
exception is unacceptable to Buyer. Upon the earlier of the end of the
Feasibility Period or expiration of such ten (10) Business Day period, Buyer
shall be deemed to have accepted all exceptions to title and all matters shown
on the Title Report other than Buyer's Title Objections, and such exceptions
shall be included in the term "PERMITTED ENCUMBRANCES" as used herein. The
Feasibility Period shall not be extended if Buyer elects to obtain an ALTA
policy.

            5.2.  REMOVAL OF OBJECTIONS. Within five (5) Business Days after
Buyer notifies Seller of Buyer's Title Objections, Seller shall notify Buyer in
writing as to whether and how Seller intends to cure Buyer's Title Objections.
If Seller notifies Buyer that Seller intends to cure a Buyer's Title Objection,
then such Buyer's Title Objection shall be deemed a "CURABLE TITLE EXCEPTION"
and the cure of such Curable Title Exception shall be deemed an additional
condition to Closing for Buyer's exclusive benefit in accordance with Section
7.1.1 but Seller's failure to complete such a cure shall not constitute a
default by Seller. If Seller elects to eliminate Buyer's Title Objection, upon
Buyer's request, Seller shall provide Buyer additional information, if
available, that may assist Buyer in determining that Buyer's Title Objections
will be removed prior to the Closing Date. Unless Seller notifies Buyer in
writing during such five (5) Business Day period that Seller intends to cure a
particular Buyer's Title Objection, then upon expiration of such five (5)
Business Day period, Seller shall be deemed unwilling to cure such Buyer's Title
Objection. Notwithstanding anything to the contrary contained herein, Seller



                                       7
<PAGE>

shall have no obligation to bring any action or proceeding or otherwise to incur
any expense whatsoever to cure or modify Buyer's Title Objections unless Seller
notifies Buyer hereunder that it intends to cure a particular Buyer's Title
Objection. If Seller is unwilling to cure or modify any or all of Buyer's Title
Objections then Buyer shall, as its sole and exclusive remedy, either (a)
terminate this Agreement by notice in writing to Seller before the earlier to
occur of (i) the Scheduled Closing Date, or (ii) five (5) Business Days
following written notice from Seller that it is unwilling to cure or modify
Buyer's Title Objections, or (b) accept such title as Seller can deliver without
any reduction in the Purchase Price, in which event such uncured Buyer's Title
Objections shall be included in the term "Permitted Encumbrances". If Buyer does
not elect to terminate this Agreement within the period described in the
immediately preceding sentence, Buyer shall be deemed to have accepted all
Buyer's Title Objections other than the Curable Title Exceptions, and such
Buyer's Title Objections shall be included in the term "Permitted Encumbrances".

      In the event of termination pursuant to this Section, each party shall
have no further rights or obligations hereunder (except that the indemnities set
forth in this Agreement shall continue notwithstanding such termination), and
the Earnest Money shall be returned to Buyer upon satisfaction of the condition
set forth in Section 17.

      The term "PERMITTED ENCUMBRANCES" as used herein includes:

            (a)   Any easement, right-of-way, encroachment, conflict,
      discrepancy, overlapping of improvements, protrusion, lien, encumbrance,
      restriction, condition, covenant or other matter with respect to the
      Property that (i) is addressed or shown on the Title Report, or that
      ordinarily would be addressed on an ALTA survey of the Property, and (ii)
      either (A) is not one of Buyer's Title Objections or (B) is not a Curable
      Title Exception.

            (b)   Non-delinquent county and city, general and special taxes, if
      any, constituting a lien at the Closing (and which shall be prorated upon
      Closing), and the lien of supplemental taxes arising on or after the
      Closing Date, if any, pursuant to the provisions of Chapter 3.5 of the
      California Revenue and Taxation Code;

            (c)   The Restrictions;

            (d)   Any Buyer's Title Objections that remain uncured, for whatever
      reason, at the date of Closing hereunder (except for title matters
      (including liens or other encumbrances) that Seller has agreed to cure);

            (e)   Any Land Use Changes of the kind described in Section 13
      created, imposed or effected before the Closing;

            (f)   The Sorrento Hills Landscape Maintenance District, the right
      of the Sorrento Hills Landscape Maintenance District to impose taxes on
      the Property and any non-delinquent taxes imposed by Sorrento Hills
      Landscape Maintenance District constituting a lien at the Closing which
      shall be prorated at the Closing;



                                       8
<PAGE>

            (g)   Any other lien voluntarily imposed by Buyer as of the Closing;
      and

            (h)   The PID Permit.

            5.3.  REVIEW OF SUPPLEMENTAL REPORTS. Escrow Holder shall cause
Title Company to issue to Buyer and Seller a supplemental preliminary report
("SUPPLEMENTAL REPORT") referencing any title exceptions against the Property,
in addition to those specified in the Title Report, which Escrow Holder
discovers before the Scheduled Closing Date.

            (a)   If any such exceptions are unacceptable to Buyer, then Buyer
      shall, within five (5) Business Days after receipt of the Supplemental
      Report, notify Seller in writing of such fact and the reasons therefor
      ("BUYER'S SUPPLEMENTAL TITLE OBJECTIONS"). Upon expiration of said five
      (5) Business Day period, Buyer shall be deemed to have accepted all
      exceptions to title and all other matters shown on the Supplemental Report
      other than Buyer's Supplemental Title Objections, and such exceptions
      shall be included in the term "Permitted Encumbrances" as used herein.

            (b)   Notwithstanding anything to the contrary contained herein,
      Seller shall have no obligation to bring any action or proceeding or
      otherwise to incur any expense whatsoever to cure or modify Buyer's
      Supplemental Title Objections unless Seller notifies Buyer hereunder that
      it intends to cure the objection. Within five (5) Business Days after
      Buyer notifies Seller of Buyer's Supplemental Title Objections, Seller
      shall notify Buyer in writing as to whether and how Seller intends to cure
      Buyer's Supplemental Title Objections prior to the Scheduled Closing Date.
      If Seller notifies Buyer that Seller intends to cure a Buyer's
      Supplemental Title Objection, then such Buyer's Supplemental Title
      Objection shall be deemed a Curable Title Exception and the cure of such
      Curable Title Exception shall be deemed an additional condition to Closing
      for Buyer's exclusive benefit in accordance with Section 7.1.1 herewith
      but Seller's failure to complete such a cure shall not constitute a
      default by Seller. Unless Seller notifies Buyer in writing during such
      five (5) Business Day period that Seller intends to cure a particular
      Buyer's Supplemental Title Objection, then upon expiration of such five
      (5) Business Day period, Seller shall be deemed to be unwilling to cure
      such Buyer's Supplemental Title Objection. If Seller is unwilling to cure
      or modify any or all of Buyer's Supplemental Title Objections, then Buyer
      shall, as its sole and exclusive remedy, either (a) terminate this
      Agreement by notice in writing to Seller before the earlier to occur of
      (i) the Scheduled Closing Date, or (ii) five (5) Business Days following
      written notice from Seller that it is unwilling to cure or modify Buyer's
      Supplemental Title Objections, or (b) accept such title as Seller can
      deliver without any reduction in the Purchase Price, in which event such
      uncured Buyer's Supplemental Title Objections shall be included in the
      term "Permitted Encumbrances". If Buyer does not elect to terminate this
      Agreement within the period described in the immediately preceding
      sentence, Buyer shall be deemed to have accepted all Buyer's Supplemental
      Title Objections other than the Curable Title Exceptions, and such Buyer's
      Supplemental Title Objections shall be included in the term "Permitted
      Encumbrances". If necessary, the Scheduled Closing Date shall be postponed
      for such period of time as may be required to accomplish the foregoing
      review and approval or termination.



                                       9
<PAGE>

            In the event of termination pursuant to this Section, each party
shall have no further rights or obligations hereunder (except that the
indemnities set forth in this Agreement shall continue notwithstanding such
termination), and the Earnest Money shall be returned to Buyer upon satisfaction
of the condition set forth in Section 17.

      6.    DELIVERIES AND EXECUTION AT CLOSING.

            6.1.  SELLER'S DELIVERIES. Prior to 3:00 P.M. local time on the last

      ("IRC SECTION 1445"), or a certificate from the Internal Revenue Service
      to the effect that no portion of the purchase price is subject to
      withholding under IRC Section 1445;

                  (d)   If the facts in such form would be true, a California
      form 590, to the effect that Seller has a permanent place of business in

                  (e)   A Partial Assignment of Warranties in the form of
      EXHIBIT "K";

                  (f)   Such documentary and other evidence as may reasonably be
      required by Escrow Holder evidencing the status and capacity of Seller and
      the authority of the person or persons who are executing the various
      documents on behalf of Seller in connection with this Agreement.

            6.2.  BUYER'S DELIVERIES. Prior to 3:00 P.M. local time on the last
Business Day before the Scheduled Closing Date, Buyer shall deliver to Escrow
Holder each of the following, duly executed and acknowledged, if required:

                  (a)   The balance of the Purchase Price plus the amount, if
      any, required of Buyer with respect to prorations and costs as set forth
      in Sections 7.4 or 7.5;

                  (b)   An Undertaking of Representations and Warranties and

      and

                  (d)   Such documentary and other evidence as may be reasonably

      Buyer and the



                                       10
<PAGE>

      authority of the person or persons who are executing the various documents

      7.    CLOSING.

            7.1.  CLOSING CONDITIONS.

                  7.1.1. THE CONDITIONS. Each of the following items shall be a

      Property and the improvements thereon, the nature and condition of the
      existing permits and approvals for the Property, the Seller Diligence
      Deliveries, the availability or non-availability of any other governmental
      approvals required for use of the Property, the financial feasibility of
      the Property, and the effect of any governmental rules, regulations,
      statutes or ordinances applicable to any of the foregoing, and any and all

                         (e)   Buyer shall have delivered the Feasibility
      Deposit to Escrow Holder, at or before the end of the Feasibility Period.
      Buyer shall be under no obligation to deliver the Feasibility Deposit, but
      the delivery of the Feasibility Deposit to Escrow Holder shall be deemed
      to constitute (i) Buyer's election to purchase the Property on an "AS-IS,
      WHERE-IS" basis in accordance with Section 10, without any continuing
      representations or warranties of Seller of any kind except as set forth in
      Section 9 (the



                                       11
<PAGE>

      foregoing clause (i) is not intended to negate the covenants to be made by
      Seller in the Right of First Offer), and (ii) Buyer's agreement that the
      condition set forth in clause (d) of this Subsection 7.1.1 has been
      satisfied or waived by Buyer, and that from and after the delivery of the

      to the closing of the Escrow.

                        (f)   The Title Company shall be unconditionally
      prepared to deliver the Title Company's standard coverage CLTA Owner's
      Policy of Title Insurance with a CLTA Form 101.1 mechanic's lien

      Closing to Buyer, insuring Buyer in an amount equal to the Purchase Price,
      and showing good and marketable fee simple title to the Property vested in
      Buyer free and clear of all covenants, conditions, rights, rights of way,
      easements, liens, encumbrances, or other matters affecting title to or use
      of the Property, except:

                              (i)    The customary printed exceptions contained
                                     in Buyer's Title Policy;

                              (ii)   The Permitted Encumbrances; and

                        (g)   The final map shall have been recorded through the
      due diligence and good faith efforts of Seller, such that the Property
      shall consist only of one or more parcels or lots that comply with the
      California Subdivision Map Act ("FINAL MAP"). Notwithstanding anything
      herein to the contrary, Buyer shall have the option to terminate the
      Agreement pursuant to this Section 7 and Section 17 herein, if the Final
      Map has not been recorded by December 30, 2001 ("ESCROW TERMINATION
      DATE").

                        (h)   Seller shall have delivered, promptly upon its
      issuance, a Soils Certificate and Engineer's Certificate [each in the form
      described in Section 37] to Buyer and Escrow Holder for the Property, and
      met other conditions, if any, set forth as Seller Improvements in Section
      11 herein.

            If Buyer elects, in accordance with Section 5.1, to obtain an ALTA
Extended Coverage Owner's Policy of Title Insurance in lieu of the CLTA policy
of title insurance specified above, then the reference in this Section 7.1 to
"Buyer's Title Policy" shall mean and refer to such ALTA policy of title
insurance.

precedent described in clauses (a), (d), (f), (g) and (h) of Subsection 7.1.1

            7.2.  THE CLOSING. Escrow Holder shall close the Escrow on the date
when each and every condition described in Subsection 7.1.1. has been satisfied
or waived by (a) filing for record the following items in the following order:
(i) the Deed and such other documents as may be necessary to procure Buyer's
Title Policy, (ii) the Right of First Offer and (iii) such other documents as
may be necessary, and then (b) delivering funds and documents as set forth
herein.

            7.3.  FAILURE OF TIMELY SATISFACTION OF CONDITIONS.

                  7.3.1. If Escrow Holder cannot close the Escrow on or before
the Scheduled Closing Date, then it will, nevertheless, close the Escrow when
all conditions have been satisfied or waived, notwithstanding that one or more
of such conditions has not been timely performed, unless a notice of termination
shall have been delivered to Escrow Holder at that time by a party that is not
then in default under this Agreement. The right so to terminate the Escrow and
this Agreement shall be optional, not mandatory. No delay in the giving of such
notice shall affect the rights hereunder of the party giving the same.
Notwithstanding the foregoing, the Escrow and this Agreement shall terminate if
the Closing does not occur before the Escrow Termination Date.

                  7.3.2. Escrow Holder shall have no liability or responsibility
for determining whether or not a party giving a notice of termination is or is
not in default hereunder. Within two Business Days after receipt of such notice
from one party, Escrow Holder shall deliver a copy of such notice to the other
party. Unless written objection to the termination of the Escrow is received by
Escrow Holder within ten (10) days after Escrow Holder delivers such notice to
the other party, (a) Escrow Holder shall forthwith terminate the Escrow and
return all funds, documents and other items held by it to the party depositing
same, except that Escrow Holder may retain such documents and other items
usually retained by escrow agents in accordance with standard escrow termination
procedures and practices, and (b) each party shall forthwith pay to Escrow
Holder one-half of Escrow Holder's reasonable escrow termination charges. If
written objection to the termination of the Escrow is delivered to Escrow Holder
within such ten (10) day period, then Escrow Holder is authorized to hold all
funds, documents and other items delivered to it in connection with the escrow
and may, in Escrow Holder's sole discretion, take no further action until
otherwise directed, either by the parties' mutual written instructions or final
order of a court of competent jurisdiction.

                  7.3.3. Neither (a) the exercise of the right of termination,
(b) delay in the exercise of such right, nor (c) the return of funds, documents
or other items, shall affect the right of the party giving a notice of
termination to pursue its remedy described in Section 16 hereof. Nor shall (i)
the giving of such notice, (ii) the failure to object to termination of the
Escrow, or (iii) the return of funds, documents or other items affect the right
of the other party to pursue its remedy described in Section 16 hereof.

            7.4.  PRORATION OF REAL ESTATE TAXES. Real estate taxes for the then
current year relating to the Property shall be prorated as of the Closing Date.
In the event that the Property is not separately assessed by applicable taxing
authorities and is assessed together with other property of Seller, then for
purposes of the proration set forth herein, the taxes attributable to the
Property shall be calculated by multiplying the total taxes covered by the
applicable tax



                                       13
<PAGE>

bill by a fraction, the numerator of which is the number of square feet of the
Property and the denominator of which is the total number of square feet of land
(including the Property) covered by such tax bill; provided, however, the real
estate taxes attributable to the value of any building improvements shall be
attributed to the property upon which such building improvements are located. If
the Closing shall occur before the actual taxes for the then current year
(excluding supplemental taxes arising as a consequence of the sale of the
Property) are known, the proration of taxes shall be upon the basis of taxes for
the Property (calculated as aforesaid, if the Property is not separately
assessed) for the immediately preceding year; provided that, if the taxes for
the current year (excluding supplemental taxes arising as a consequence of the
sale of the Property) are thereafter determined to differ from the taxes for the
preceding year (after any appeal of the assessed valuation thereof is concluded)
by more than One Hundred Dollars ($100), then Buyer and Seller shall promptly
adjust the proration of such taxes, with Seller or Buyer, as the case may be,
paying to the other any amount required as a result of such adjustment. All
special taxes and assessments actually assessed prior to the Closing Date shall
be prorated as set forth above, and those assessed after the Closing Date shall
be paid by Buyer. Under no circumstances shall Seller be responsible for any
property taxes to the extent such taxes increase as a result of the sale of the
Property to Buyer or Buyer's ownership, use or development of the Property. This
Section 7.4 shall not merge with the deed delivered hereunder but shall survive
Closing.

            7.5.  COSTS AND EXPENSES OF CLOSING.

                  7.5.1. Seller shall pay (a) County Documentary Transfer Tax,
in the amount Escrow Holder determines to be required by law, (b) the cost of
any survey and the CLTA Title Policy premium for Buyer's Title Policy, (c)
one-half of Escrow Holder's escrow fee or escrow termination charge, (d) fees
for beneficiaries' statements, and (e) usual seller's document drafting and
recording charges.

                  7.5.2. Buyer shall pay (a) one-half of Escrow Holder's escrow
fee or escrow termination charge, (b) the extra cost of any ALTA Title Policy
ordered by Buyer in the manner permitted by this Agreement, (c) the cost of any
endorsements to Buyer's Title Policy requested by Buyer other than the mechanics
lien endorsement, and (d) usual buyer's document drafting and recording charges.

                  7.5.3. Each party shall be responsible for the payment of its
own attorneys' fees incurred in connection with the negotiation of this
Agreement.

            7.6.  DISTRIBUTION OF FUNDS AND DOCUMENTS.

                  7.6.1. Escrow Holder shall, at the Closing, disburse (a) to
Seller, or order, the Earnest Money (to the extent not previously disbursed to
Seller) and the balance of the Purchase Price, plus or minus (i) any appropriate
prorations or other charges, and (ii) any amounts properly withheld with respect
to Seller's income taxes under California Revenue and Taxation Code Sections
18662 and 18668 (up to three and one-third percent of the Purchase Price), and
(b) to Buyer, or order, any excess funds theretofore delivered to Escrow Holder
by Buyer.

<PAGE>

                  7.6.2. Escrow Holder shall cause the recorder's office to mail
the Deed (and each other document which is herein expressed to be, or by general
usage is, recorded) after recordation, to the grantee, beneficiary or person (a)
acquiring rights under said document, or (b) for whose benefit said document was
acquired. Escrow Holder shall further provide promptly to each of Buyer and
Seller conformed copies of all such recorded documents bearing the pertinent
recording data.

                  7.6.3. Escrow Holder shall, at the Closing, deliver by United
States mail (or hold for personal pickup, if requested) each non-recorded
document received hereunder by Escrow Holder, to the payee or person (a)
acquiring rights under said document, or (b) for whose benefit said document was
acquired.

      10.   LIMITATIONS ON REPRESENTATIONS AND WARRANTIES.

            10.1. PROPERTY CONDITION. BUYER ACKNOWLEDGES THAT THE
REPRESENTATIONS AND WARRANTIES OF SELLER SET FORTH IN SECTION 9 HEREOF SHALL

      11.   SELLER'S DEVELOPMENT OBLIGATIONS. Seller shall be responsible for
completing or causing to be completed the Seller's Improvements in accordance
with this Agreement. Nothing contained in this Agreement shall obligate Seller
in any way to develop or construct any specific improvements on the Property or
in Torrey Hills or any of Seller's other land except as specifically set forth
herein.

            11.1. INFRASTRUCTURE ROAD AND GRADING IMPROVEMENTS: Seller has
completed Vista Sorrento Parkway to its intersection with Rose Coral Row. Prior
to Closing, Seller shall complete Vista Sorrento Parkway to Calle Mar de
Mariposa, and Calle Mar de Mariposa from Vista Sorrento Parkway to West Ocean
Air Drive (including the modified intersection of Vista Sorrento Parkway and

Seller shall also complete the grading for the Property in accordance with
City-approved grading plans, as evidenced by delivery of a Soils Certificate
(defined in Section 37 herein) to Buyer and Escrow Holder promptly upon its

            12.2. ADTs. Under the existing development entitlements for Torrey
Hills, a limited number of average daily trips ("ADTs") have been allocated to
Torrey Hills and the portion of Torrey Hills where the Property is located.
Seller shall cooperate reasonably with Buyer to effect an allocation of Seller's
ADTs to the Property consistent with Buyer's Improvements, but such Seller
allocation shall not exceed Buyer's Maximum ADT Allocation. Buyer shall neither
use nor seek an allocation of Seller-owned ADTs owned by Seller to the Property
in an amount greater than Buyer's Maximum ADT Allocation. Seller shall have the
right to allocate and control the allocation of any ADTs, which are not
allocated by Seller to Buyer and the Property or used by Buyer, for Seller's use
in connection with the development of the balance of Torrey Hills. This Section
12.2 shall survive the Closing.

            12.3. INDEMNIFICATION. Buyer shall indemnify, protect, defend (with
counsel approved by Seller) and hold harmless Seller, its contractors and
Seller's employees from and against any and all injuries, losses, liens, claims,
judgments, liabilities, costs, expenses and damages (including reasonable
attorneys' fees and court costs) sustained by or threatened against Seller, its
contractors and its employees which result from, arise out of or relate to the
Property after the Closing, or Buyer's use or development of the Property,
except to the extent caused by Seller's gross negligence or willful misconduct.
Buyer's indemnity shall survive Closing and completion of Buyer's Improvements
to the Property.

      13.   RELATION TO OTHER PROPERTY.

            13.1. LAND USE CHANGES. Buyer acknowledges that the Property is part
of Torrey Hills and that Seller intends to, but except as expressly set forth in
this Agreement shall have no obligation to, develop the remaining land in Torrey
Hills for among other purposes, residential, commercial and industrial uses.
Buyer shall reasonably cooperate with Seller with respect to such development
and take all steps reasonably requested by Seller in connection therewith,
provided Seller shall reimburse Buyer for any material out-of-pocket costs
associated therewith. Such steps shall include without limitation, the
following:

                  (a)   In addition to complying with the requirements of any
      Permitted Encumbrances affecting the Property, including but not limited
      to the Sorrento Hills Landscape Maintenance District (or the Torrey Hills
      Master Association in the event the Sorrento Hills Landscape Maintenance
      District fails or is dissolved), Buyer shall reasonably cooperate with
      Seller with respect to, and shall not oppose, (i) all applications
      proposed or supported by Seller for zoning changes, resubdivisions,
      planned residential development permits, planned industrial development
      permits, planned commercial development permits, conditional use permits,
      (ii) maintenance or other assessment district for streets, common areas
      and landscaping (iii) any covenants, conditions and restrictions
      encompassing all or part of the Property and/or Torrey Hills proposed by
      Seller which establish architectural guidelines and restrictions, an
      architectural review committee, allocation of the costs thereof, and
      remedies to assure compliance therewith; or any other land use approval or
      modifications to any of the foregoing, provided that the same are
      applicable generally to similar commercial properties within Torrey Hills,
      do not preclude Buyer's construction and maintenance of the Buyer's
      Improvements and do



                                       19
<PAGE>

      not unreasonably discriminate against the Property (collectively, "LAND
      USE CHANGES"); and

                  (b)   Buyer shall not propose or support any Land Use Change
      to the Property or any other portion of Torrey Hills if Seller notifies
      Buyer that such Land Use Change reasonably might be anticipated to have a
      material adverse effect upon Seller's intended development of the
      remainder of Torrey Hills.

            13.2. TRADE NAMES AND TRADEMARKS. Buyer agrees not to use any
trademark, trade name or service mark in connection with the use of the name
"Torrey Hills", the Torrey Hills logo, other trademarks of Torrey Hills, use of
the name "Westbrook", "TERRABROOK" or any combination of words deceptively
similar thereto in connection with any of its marketing, advertising or the
establishment of any ownership entity associated with Buyer or its Affiliates,
without the express prior written approval of Seller, which approval Seller may
withhold in its sole discretion. Notwithstanding the above, so long as Buyer
remains in good standing under this Agreement, Seller approves Buyer's use of
the phrase "at Torrey Hills" for locational and geographic identification
purposes only. This Section 13.2 shall survive Closing.

            13.3. DEVELOPMENT AGREEMENT. Seller shall cause the Title Company to
issue an endorsement to the Buyer's Title Policy insuring against Buyer having
any obligations under Seller's Development Agreement with City.[CONFIRM WITH
PARTIES.]

      14.   COMMUNITY FACILITIES DISTRICT.

            14.1. DISTRICTS. The Property has been encumbered by community
facilities districts as defined in the Mello-Roos Community Facilities Act of
1982, as amended (the ACT). In order to facilitate the development of the
Property, Buyer hereby consents to and acknowledges the formation of Community
Facilities District 95-1 of the Del Mar Union Elementary School District and
Community Facilities District 95-1 of the San Dieguito Union High School
District (collectively, the "DISTRICTS") and the imposition of special taxes by
the Districts upon the Property, if any.

            14.2. NOTICE OF SPECIAL TAX. At least five (5) days before the end
of the Feasibility Period, Seller shall deliver to Buyer, a Notice of Special
Tax which is being furnished in accordance with the requirements of Section
53341.5 of the California Government Code.

      15.   CONDEMNATION. Promptly after obtaining knowledge of the institution
of proceedings for the condemnation of any part of the Property, Seller or Buyer
will notify the other of the pendency of such proceedings and, if then
reasonably available, such notification shall include the following: (i) the
specific portions of the Property to be taken; (ii) the compensation to be paid
for such taking; (iii) the date upon which the taking is to occur; and (iv) the
proposed use of the property to be taken. In the event of the condemnation of
any portion of the Property or the sale of any portion of the Property in lieu
of condemnation, this Agreement shall remain in full force and effect, and in
such event Seller shall assign to Buyer any and all claims for the proceeds of
such condemnation or sale, and Buyer shall take title to the remainder of the
Property with the assignment of such proceeds and subject to such condemnation
and



                                       20
<PAGE>

without reduction in the Purchase Price; provided, however, that if after such
condemnation or conveyance in lieu thereof the remainder of the Property would
no longer be suitable for Buyer's purposes or the award is not sufficient
compensation for the taking in Buyer's sole determination, then Buyer may
terminate this Agreement by providing notice to Seller within five (5) days
following Seller's notice of such condemnation of the Property. If Buyer does
not elect to terminate within such five (5) day period following such notice by
Seller, Buyer shall be deemed to have waived all rights to terminate pursuant to
this provision, and this Agreement shall remain in full force and effect.

      16.   REMEDIES.

            16.1. REMEDIES FOR BREACH BY SELLER. IN THE EVENT THAT, BEFORE THE
CLOSING, SELLER SHALL BREACH ANY OF ITS OBLIGATIONS HEREUNDER OR CAUSE THE
CLOSING NOT TO OCCUR FOR ANY REASON, EXCEPT BUYER'S DEFAULT OR A TERMINATION OF
THIS AGREEMENT BY BUYER OR SELLER PURSUANT TO A RIGHT TO DO SO UNDER THE

PROVIDED THAT SUCH DAMAGES SHALL IN NO EVENT EXCEED $300,000, OR (II) BRING AN
ACTION FOR SPECIFIC PERFORMANCE. NOTWITHSTANDING THE FOREGOING, BUYER SHALL HAVE
NO RIGHT TO BRING AN ACTION FOR SPECIFIC PERFORMANCE UNLESS BUYER SHALL HAVE (1)
ON OR PRIOR TO THE CLOSING DATE TENDERED TO ESCROW THE FULL CASH CONSIDERATION,
SATISFIED EACH AND EVERY OTHER CONDITION TO THE CLOSING, AND NOT OTHERWISE BE IN
DEFAULT, AND (2) SENT SELLER A WRITTEN DEMAND TO CLOSE ESCROW WITHIN TEN (10)
DAYS OF SUCH NOTICE, AND SELLER SHALL HAVE FAILED TO CLOSE IN ACCORDANCE WITH
THE TERMS OF THIS AGREEMENT. ANY SUCH SPECIFIC PERFORMANCE MUST BE BROUGHT, IF

            THIS SECTION 16.1 SHALL NOT LIMIT OR ADVERSELY AFFECT BUYER'S RIGHTS
WITH RESPECT TO THE MUTUAL INDEMNITIES SET FORTH IN SECTION 25, OR ANY REMEDY
UNDER SECTION 17 OR SECTION 35 OR THE RIGHT TO RECOVER FEES AND EXPENSES IN
ACCORDANCE WITH SECTION 22.

            16.2. REMEDIES FOR BREACH BY BUYER. IN THE EVENT THAT, BEFORE THE

TERMS AND PROVISIONS HEREOF, THEN SELLER MAY, AS ITS SOLE AND EXCLUSIVE REMEDY,

THE TERMINATION DELIVERABLES FROM BUYER, PROVIDED, HOWEVER, THAT THIS SECTION
16.2 SHALL NOT LIMIT OR ADVERSELY AFFECT SELLER'S RIGHTS WITH RESPECT TO
INDEMNIFICATION UNDER SECTION 4.3 OR SECTION 12, THE MUTUAL INDEMNITIES SET
FORTH IN SECTION 25, ANY REMEDY UNDER SECTION 17 OR SECTION 35 OR THE RIGHT TO
RECOVER FEES AND EXPENSES IN ACCORDANCE WITH SECTION 22.

            16.3. GENERAL PROVISIONS. IN THE EVENT OF ANY SUCH TERMINATION BY
SELLER OR BUYER, THE MUTUAL INDEMNITIES SET FORTH IN SECTION 25 AND THE
INDEMNITY BY BUYER SET FORTH IN SECTION 4.3 SHALL, NONETHELESS, CONTINUE. THE
PARTIES AGREE THAT SELLER WILL SUFFER DAMAGES IN THE EVENT OF BUYER'S DEFAULT ON
ITS OBLIGATIONS. ALTHOUGH THE AMOUNT OF SUCH DAMAGES ARE DIFFICULT OR IMPOSSIBLE
TO DETERMINE, THE PARTIES AGREE THAT EXCEPT WITH RESPECT TO A BREACH OF SECTION
17 OR SECTION 35, THE RIGHT TO INDEMNIFICATION UNDER SECTION 4.3 AND SECTION 25,
AND THE RIGHT TO RECOVER FEES AND EXPENSES IN ACCORDANCE WITH SECTION 22, THE
AMOUNT OF THE EARNEST MONEY TOGETHER WITH RECEIPT OF THE TERMINATION
DELIVERABLES IS A REASONABLE ESTIMATE OF SELLER'S LOSS IN THE EVENT OF BUYER'S
DEFAULT. THUS, EXCEPT WITH RESPECT TO A BREACH OF SECTION 17 OR SECTION 35, THE
RIGHT TO INDEMNIFICATION UNDER SECTION 4.3 AND SECTION 12, AND THE RIGHT TO
RECOVER FEES AND EXPENSES IN ACCORDANCE WITH SECTION 22, SELLER SHALL ACCEPT AND
RETAIN THE EARNEST MONEY AS LIQUIDATED DAMAGES BUT NOT AS A PENALTY.

            16.4. EVENT OF BANKRUPTCY. Buyer and Seller acknowledge that the
provisions of this Agreement contemplate a material contractual business
relationship between the parties which contains material executory obligations
of both parties and that any delay, doubt or uncertainty concerning the
performance or status of this Agreement is likely to cause substantial injury
and irreparable harm to the other party hereto. Accordingly, if either Buyer or
Seller shall become a debtor under the United States Bankruptcy Code, as
hereafter amended or modified (the "BANKRUPTCY CODE"), voluntarily or
involuntarily (such party becoming a debtor hereinafter the "DEBTOR" and such
party not being the Debtor hereinafter the "NON-DEBTOR"), Buyer and Seller agree
as follows:

                  (a)   If the Non-Debtor is prevented from exercising any of
its rights or remedies under this Agreement without first obtaining leave of the
Bankruptcy Court, then the



                                       22
<PAGE>

Debtor will, within thirty (30) days of the filing of the bankruptcy petition,
arrange for and cause to be filed a motion to assume or reject this Agreement
and will perform all of the obligations under this Agreement as if this
Agreement were within the purview of Section 365(d)(3) of the Bankruptcy Code.
Buyer and Seller specifically acknowledge that "cause" and other good and
sufficient grounds exist for the setting of the specified period of time for the
Debtor to assume or reject this Agreement.

                  (b)   Any costs, damages or expenses incurred by the
Non-Debtor due to any post-petition default(s) shall be treated as
administrative claims under the Bankruptcy Code.

                  (c)   The Non-Debtor shall receive adequate protection pending
and prior to a determination on any motion to assume or reject this Agreement.

                  (d)   If the Non-Debtor is required to perform or pay any
post-petition obligation of the Debtor, then all amounts so paid or any damages
incurred will be entitled to administrative priority.

                  (e)   Any person to whom or entity to which this Agreement may
be assigned pursuant to the provisions of the Bankruptcy Code shall be deemed
without further act or deed to have assumed all of the obligations arising under
this Agreement on and after the date of such assignment; provided that nothing
herein shall be deemed a consent to any such assignment.

                  (f)   Nothing contained in this Section 16.4 or its
subsections shall be deemed to limit or restrict the Non-Debtor's right to seek
in the bankruptcy court any relief that the Non-Debtor may deem appropriate in
the event of a bankruptcy, and in particular, shall not preclude either party
from seeking to oppose the ability to reject this Agreement. The Non-Debtor
shall be free to seek the dismissal or conversion of any case, to compel
assumption or rejection of this Agreement, the appointment of a trustee or
examiner, and relief from the automatic stay.

      17.   EFFECT OF TERMINATION. If this Agreement terminates and neither
Buyer nor Seller is then in default, Buyer and Seller shall have no further
obligations under this Agreement, except that the obligations set forth in this
Section 17, the mutual indemnitees set forth in Section 25 and the indemnity by
Buyer set forth in Section 4.3 shall continue notwithstanding such termination.
Notwithstanding anything in this Agreement to the contrary, if this Agreement
shall terminate in accordance with its terms for any reason, then Buyer shall,
within five (5) Business Days after the effective date of such termination,
deliver to Seller the following items (the "TERMINATION DELIVERABLES"): (i)
Buyer's Quitclaim Deed to the Property, (ii) true and complete copies of any
surveys, market studies, soils reports, architectural drawings, plans and
renderings, engineering plans and drawings, feasibility studies, tenant
commitment letters, appraisals, environmental reports, any permits or other
approvals that Buyer has obtained in connection with the Property, and any other
due diligence or development documents produced or obtained by Buyer in
connection with its investigation or planned development of the Property
(collectively, the "BUYER DEVELOPMENT DOCUMENTS"), except Buyer shall have no
obligation to



                                       23
<PAGE>

deliver the Buyer Development Documents in the event of Seller's default
hereunder, (iii) an Assignment of Work Product in the form of EXHIBIT "I"
attached hereto duly executed by Buyer and (iv) a Release in the form of EXHIBIT
"J" duly executed by Buyer. If (x) this Agreement shall terminate in accordance
with its terms before the end of the Feasibility Period, (y) neither Buyer nor
Seller shall be in default of any of its Agreements contained herein and (z)
Buyer shall have delivered all of the Termination Deliverables to Seller, then
Buyer shall be entitled to a refund of the Earnest Money. Notwithstanding
anything contained in this Agreement to the contrary, Buyer shall have no
entitlement to any portion of the Earnest Money, and neither Escrow Holder nor
Seller shall have any obligation to pay any portion of the Earnest Money to
Buyer, unless and until Buyer shall have delivered the Termination Deliverables
(except the Buyer Development Documents in the event of Seller's default
hereunder) to Seller. If Buyer shall have failed to deliver the Termination
Deliverables to Seller in the manner and within the time period set forth above,
then Escrow Holder shall pay any portion of the Earnest Money in its possession
to Seller, and Seller shall be entitled to retain any portion of the Earnest
Money previously paid to Seller and to seek appropriate legal relief at law or
in equity with respect to Buyer's failure to perform in accordance with this
Section 17.

      18.   ORDER OF REFERENCE. ANY CONTROVERSY OR CLAIM ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE PERFORMANCE THEREOF SHALL BE REFERRED PURSUANT
TO THE PROVISION OF CALIFORNIA CODE OF CIVIL PROCEDURE, SECTIONS 638 ET SEQ.
("REFERENCE"), BY ANY COURT OF COMPETENT JURISDICTION TO A RETIRED JUDGE OR
JUSTICE FROM THE PANEL MEMBERS OF JAMS/ENDISPUTE, SAN DIEGO COUNTY OFFICE, OR
ANY SUCCESSOR ORGANIZATION TO TRY ALL OF THE ISSUES INCLUDING ALL PRE-TRIAL AND
POST-TRIAL HEARINGS, MOTIONS AND MATTERS OF ANY KIND WHETHER OF FACT OR OF LAW
AND REPORT A STATEMENT OF DECISIONS THEREON WHICH SHALL STAND AS A DECISION OF
THE COURT. THE PARTIES, IN SELECTING THIS PROCESS, FOR THEMSELVES, THEIR AGENTS,
HEIRS, ASSIGNS, SUCCESSORS IN INTEREST AND/OR ANY PERSON, FIRM, OR ORGANIZATION
ACTING FOR OR THROUGH THEM DO HEREBY WAIVE THEIR RIGHT TO A TRIAL BY JURY. NO
PROVISION OF THIS SECTION 18 SHALL LIMIT THE RIGHT OF ANY PARTY TO THIS
AGREEMENT TO EXERCISE SELF-HELP REMEDIES SUCH AS SETOFF, NON-JUDICIAL
FORECLOSURE AGAINST OR SALE OF ANY REAL OR PERSONAL PROPERTY, COLLATERAL OR
SECURITY, OR TO OBTAIN PROVISIONAL OR ANCILLARY REMEDIES FROM A COURT OF
COMPETENT JURISDICTION BEFORE, AFTER, OR DURING THE PENDENCY OF ANY REFERENCE OR
OTHER PROCEEDINGS. THE EXERCISE OF A REMEDY DOES NOT WAIVE THE RIGHT OF EITHER
PARTY TO RESORT TO JUDICIAL REFERENCE.

      19.   ASSIGNMENT.

            19.1. BY SELLER. Seller shall have the right to assign its interest
in this Agreement:

                  (a)   to any partnership, corporation, joint venture, limited
liability company or other person that acquires Seller's interest in the
Property and that assumes Seller's obligations hereunder; or

                  (b)   to any other person or entity upon the written consent
of Buyer, which consent shall not be unreasonably withheld or delayed. In
determining the reasonableness of withholding consent, the capacity of the
proposed assignee to perform Seller's obligations under this Agreement and any
related agreements shall be considered.

            In the event of any assignment by Seller, Seller shall be relieved
of all of its obligations hereunder.

            19.2. BY BUYER. Except as set forth in the next sentence hereof,
Buyer shall have no right to assign its interest in the Property or this
Agreement to any person or entity. Notwithstanding the foregoing, Buyer shall
have the right to assign its interest in this Agreement (i) to a corporation,
partnership or other company that is controlled by Buyer, (ii) to Torrey View
Associates, LLC or (iii) to an "END USER", defined for all purposes herein as a
third party entity with an unconditional obligation to Buyer to occupy at least
fifty percent (50%) of the office building constructed as part of Buyer's
Improvements, and who unconditionally assumes the obligations of Buyer under
this Agreement. Otherwise, Buyer shall have the right to assign its interest
hereunder only upon the written consent of Seller, which consent shall not be
unreasonably withheld by Seller; provided, however, it shall be reasonable for
Seller to withhold such consent if the proposed assignee, in Seller's judgment,
does not have the financial resources or the expertise in the design,
permitting, construction and marketing of commercial Class "A" office facilities
necessary to perform and insure the performance of Buyer's obligations hereunder
and under the agreements attached hereto as Exhibits. For the purposes of this
Section 19.2, "control" shall be deemed to exist if Buyer has the ability either
through the ownership of securities, capital stock or equity interests or
otherwise to control the operations of such other entity.

            19.3. GENERAL. Any assignment in contravention of this Section 19
shall be void and shall not relieve either party of its obligations and
liabilities hereunder. If Seller or Buyer hereunder is a corporation, an
unincorporated association, partnership, or limited liability company, then the
transfer, assignment, or hypothecation of any stock or interest in such
corporation, association, partnership, or limited liability company which is, in
the aggregate, greater than ten percent (10%) of the aggregate amount of such
interests shall be deemed an assignment of this Agreement. In connection with an
assignment pursuant to Section 19.1 or Section 19.2, the assigning party shall,
contemporaneously with the delivery of notice of such assignment, deliver to the
other party proof satisfactory to the other party in its reasonable business
judgment that the entity to which this Agreement has been assigned qualifies as
an assignee under such subsection.



                                       25

      20.   NOTICE. Any notice or communication required or permitted hereunder
shall be given in writing, sent by (a) personal delivery, (b) expedited delivery
service with proof of delivery, (c) United States mail, postage prepaid,
registered or certified mail, (d) telecopy (provided that such telecopy is
confirmed by expedited delivery service or by mail in the manner previously
described) addressed to the respective addresses set forth in Section 1, above,
or to such other address within the continental United States or to the
attention of such other persons as hereafter shall be designated in writing by
the applicable party sent in accordance herewith. Any such notice or
communication shall be deemed to have been given either at the time of personal
delivery or, in the case of delivery service or mail, as of the date of first
attempted delivery at the address and in the manner provided herein, or in the
case of telecopy upon receipt.

      21.   TIME LIMIT. ANY SUIT BY BUYER FOR ANY BREACH BY SELLER OF ANY
REPRESENTATION, WARRANTY OR COVENANT CONTAINED HEREIN THAT SURVIVES THE CLOSING
MUST BE FILED ON OR BEFORE THE SECOND (2ND) ANNIVERSARY OF THE SCHEDULED CLOSING
DATE OR IT SHALL BE FOREVER BARRED. NOTWITHSTANDING ANYTHING CONTAINED HEREIN TO
THE CONTRARY THIS SECTION SHALL SURVIVE THE CLOSING OR ANY TERMINATION OF THIS
AGREEMENT.

      22.   ATTORNEYS' FEES AND LEGAL EXPENSES. Should either party hereto
institute any action or proceeding in court or any arbitration or any reference
proceeding under Section 18 or similar proceeding to enforce any provision
hereof or for damages by reason of any alleged breach of any provision of this
Agreement or for any other judicial remedy, the prevailing party shall be
entitled to receive from the losing party all reasonable attorneys' fees and all
court costs in connection with said proceedings.

      23.   NO PARTNERSHIP. Seller shall not be liable to any contractor,
subcontractor, supplier, laborer, architect, engineer, purchaser, or any other
party for services performed or materials supplied or for any causes of action
arising out of or in connection with construction or sale of improvements on the
Property except for services, materials or improvements constructed by or caused
to be constructed by Seller. Seller shall not be liable for any debts or claims
accruing in favor of any such parties against Buyer or others or otherwise
against the Property. Neither party is nor shall be an agent of the other for
any purposes. Buyer and Seller agree that Seller is not a venture partner with
Buyer or with the owners of Buyer in any manner whatsoever and Seller shall not
be deemed to be in privity of contract with any contractor or provider of
services on the Property or any purchaser (other than Buyer or its permitted
assignee pursuant to Section 19.2) of the Property or any portion thereof, nor
shall any payment of funds directly to a contractor, subcontractor or provider
of services be deemed to create any third party beneficiary status or
recognition of same by Seller. Approvals granted by Seller for any matters
covered under this Agreement shall not be construed to be for the benefit of any
party other than Buyer or its permitted assignee pursuant to Section 19.2. Each
of Buyer and Seller has had the benefit of the advice of legal counsel of its
own choosing in the negotiations for and preparation of this Agreement,
including this Section 23, and has discussed this Section 23 with such counsel.

      24.   DAMAGE TO THE PROPERTY.

            24.1. MINOR DAMAGE. If there is damage to the Property prior to the
Closing and the lesser of the cost to repair such damage or the diminution in
value caused by such damage, as mutually and reasonably determined by Buyer and
Seller, is less than or equal to five percent (5%) of the Purchase Price, then
Escrow shall close pursuant to the terms of this Agreement without delay and
without any diminution in the Purchase Price, and Seller shall assign to Buyer
all of its rights under the casualty insurance policy or policies for the
Property, if any. In no event shall Seller be obligated to repair the Property.

            24.2. MAJOR DAMAGE. If there is damage to the Property prior to the
Closing and the lesser of the cost to repair such damage or the diminution in
value caused by such damage, as mutually and reasonably determined by Buyer and
Seller, exceeds five percent (5%) of the Purchase Price, then Buyer may, within
five (5) Business Days after it becomes aware of such damage, elect to terminate
this Agreement on written notice to Seller and the Escrow Holder. If Buyer fails
to timely elect to terminate this Agreement, then Escrow shall close pursuant to
the terms of this Agreement without delay and without any diminution in the
Purchase Price, and Seller shall assign to Buyer all of its rights under the
casualty insurance policy or policies for the Property, if any. In no event
shall Seller be obligated to repair the Property.

      25.   REAL ESTATE COMMISSIONS. Each party hereto represents to the other
that it has not authorized any broker or finder to act on its behalf in
connection with the sale and purchase hereunder and that it has not dealt with
any broker or finder purporting to act on behalf of any party, except for the
Broker (identified in Section 1 of this Agreement). Each party hereto agrees to
indemnify, defend and hold harmless the other party from and against any and all
losses, liens, claims, judgments, liabilities, costs, expenses or damages
(including reasonable attorneys' fees and court costs) of any kind or character
arising out of or resulting from any agreement, arrangement or understanding
alleged to have been made by such party or on its behalf with any broker or
finder in connection with this Agreement or the transaction contemplated hereby
other than such Broker. Broker's fees shall be paid through escrow.
Notwithstanding anything to the contrary contained herein, this Section shall
survive the Closing or any termination of this Agreement.

      26.   UNAVOIDABLE DELAY. Any prevention, delay or stoppage in the work of
subdivision and building and installation of offsite or onsite improvements and
common area improvements as provided for in this Agreement, including, without
limitation, the improvements to be constructed or installed by Buyer or Seller
set forth in Sections 11 and 12 of this Agreement, through acts of God, war,
inability to obtain labor or materials or reasonable substitutes therefor,
governmental regulations or controls, or other similar matters or causes beyond
the reasonable control of the party responsible for such improvements shall
extend the



                                       27
<PAGE>

time within which this Agreement requires such acts to be performed for a period
or periods equal to any such prevention, delay or stoppage and, to the extent
that such work of subdivision and building and installation of offsite or onsite
improvements and common area improvements constitutes a condition to the
Closing, the Scheduled Closing Date shall be extended for a period or periods
equal to such prevention, delay or stoppage; provided, however, that nothing in
this Section shall excuse the prompt payment of any and all amounts due from
Buyer to Seller as required herein or the performance of any act rendered
difficult solely because of the financial condition of Buyer. Without limiting
the generality of the foregoing, in no event shall Buyer's inability to obtain
construction or other financing for development of the Property, or any portion
thereof, constitute an unavoidable delay pursuant to this Section. Furthermore,
in no event shall any extension of any period of time be deemed to have occurred
unless the party seeking such extension shall have given written notice to the
other party within fifteen (15) days following the commencement of any such
delay, setting forth the facts giving rise to such extension.

      27.   ENTIRE AGREEMENT. This Agreement embodies the entire agreement
between the parties hereto and supersedes any prior understandings or written or
oral agreements, representations or warranties between the parties concerning
the Property. This Agreement cannot be varied, modified, amended or altered
except by the written agreement of the parties.

      28.   APPLICABILITY. The terms and provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
permitted successors and assigns, except as expressly set forth herein.

      29.   TIME. Time is of the essence in the performance of Buyer's
obligations under this Agreement.


      30.   CONSTRUCTION OF AGREEMENT.

            30.6. JOINT WORK PRODUCT. This Agreement is the joint work product
of both parties and shall not be construed more favorably for, or more strictly,
against either party on the grounds that such party participated more or less
fully in the preparation of this Agreement.

      31.   REPORTING OF FOREIGN INVESTMENT. Buyer and Seller agree to comply
with any and all reporting requirements applicable to the transaction which is
the subject of this Agreement which are set forth in any law, including, but not

of such compliance.

      32.   EXECUTION. This Agreement may be executed in multiple counterparts,

all times after the date of execution hereof and prior to the Closing, unless
consented to in writing by the other party, no press release or other public
disclosure concerning this transaction shall be made, and each party shall use
reasonable efforts to prevent public disclosure of this transaction and Buyer
shall use reasonable efforts to prevent public disclosure of any information
obtained by Buyer pursuant to the terms of this Agreement, other than (a) to
directors and officers of the parties, and employees, agents and affiliates of
the parties who are involved in the ordinary course of business with this
transaction, officers and employees of potential lenders and partners,
accountants, attorneys and persons employed by the inspectors performing the

Section 33 shall not allow either party to terminate this Agreement and the sole
remedy for such breach shall be damages.

      34.   PROHIBITION AGAINST RECORDATION. Buyer shall not record this
Agreement or any memorandum thereof. If this Agreement or any memorandum or
affidavit of this Agreement is filed for record by Buyer in the county where the
Property is located, then, notwithstanding any provision hereof, Buyer shall be
deemed to be in material default of this Agreement and notwithstanding any other
provision of this Agreement, Buyer shall immediately execute and deliver to
Seller a release of this Agreement in recordable form.

      35.   ESCROW. The Closing shall be accomplished through an escrow (the
"ESCROW") established with Escrow Holder. Concurrently with its execution
hereof, Buyer and Seller shall open the Escrow by Seller's delivery of a fully
executed copy of this Agreement with Escrow Holder. Buyer and Seller each shall
execute and deliver such further escrow instructions or other instruments as may
be reasonably requested by Escrow Holder from time to time, so long as the same
are consistent with this Agreement. If there is any inconsistency between Escrow
Holder's general provisions and any of the provisions of this Agreement, the
provisions of this Agreement shall control. For purposes of complying with
Internal Revenue Code Section 6045(e), as amended effective January 1, 1991,
Escrow Holder is hereby designated as the "person



                                       29
<PAGE>

responsible" and the "reporting person" for purposes of filing any information
returns with the Internal Revenue Service concerning this transaction, as may be
required by law.

            35.1. CONFLICTING DEMANDS. If Escrow Holder receives or becomes
aware of conflicting demands or claims with respect to the escrow, the rights of
any party hereto, or funds, documents or other items deposited with Escrow
Holder, Escrow Holder shall have the right to discontinue any further acts until
such conflict is resolved to its satisfaction, and it shall have the further
right to commence or defend any action for the determination of such conflict.
The parties shall, immediately after demand therefor by Escrow Holder, reimburse
Escrow Holder (in such respective proportions as the prevailing party shall
determine) any reasonable attorneys' fees and court costs incurred by Escrow
Holder pursuant to this Section.

            35.2. TAX REASSESSMENTS. Escrow Holder shall not be liable for
proration of any supplemental tax bills related to this transaction which may
hereafter be issued due to reassessments pursuant to the provisions of Chapter
3.5 of the Revenue & Taxation Code.

            35.3. ADDITIONAL RECORDING FEE. Escrow Holder is authorized and
directed to charge Buyer the additional sum of twenty dollars ($20.00) for
recording fees, in the event that Escrow Holder has not been presented with a
Preliminary Change of Ownership report form prior to the close of Escrow,
adequate to satisfy the requirements of Revenue & Taxation Code Sections 480.3
and 480.4.

            35.4. DISBURSEMENTS FROM ESCROW. All disbursements from the Escrow
shall be made by Escrow Holder's trust account check unless Escrow Holder
receives written instructions to the contrary. Escrow Holder shall disburse
funds by wire if the recipient or the recipient's agent requests such
disbursement in writing.

      36.   OFFER: EXPIRATION. In order to constitute a valid offer, this
Agreement must be executed by Buyer and delivered to Seller. The execution of
this Agreement by Buyer and the delivery hereof to Seller shall constitute an
offer which shall be automatically revoked, withdrawn and terminated unless
Seller accepts same by executing this Agreement and delivering one fully
executed copy thereof to Escrow Holder within two (2) Business Days after
receipt thereof by Seller. Escrow Holder promptly shall inform Buyer of Seller's
delivery of the executed Agreement.

      RIGHT OF FIRST OFFER, RIGHT TO REPURCHASE AND AGREEMENT

      THIS AGREEMENT OF RIGHT OF FIRST OFFER, RIGHT TO REPURCHASE AND AGREEMENT
(the "AGREEMENT") is granted this ___ day of ___________, 200_, by TORREY VIEW
PHASE II, L.P., a California limited partnership ("BUYER") to WESTBROOK TORREY
HILLS, L.P., a Delaware limited partnership ("SELLER"), upon the following terms
and conditions:

                                 R E C I T A L S

      A.    Pursuant to that certain Commercial Land Purchase and Sale Agreement
and Joint Escrow Instructions between Buyer and Seller dated for reference
purposes as of July 10, 2001 (the "PURCHASE AGREEMENT"), concurrently herewith
Seller is conveying to Buyer the real property (the "PROPERTY") located in the
City of San Diego (the "CITY"), State of California, more particularly described
on Exhibit "1" attached hereto and incorporated herein by this reference. The
Purchase Agreement requires Buyer to pay Five Million Fifty-six Thousand and
00/100 Dollars ($5,056,000.00) (the "PURCHASE AGREEMENT PURCHASE PRICE") to
Seller as consideration for the purchase of the Property.

      B.    As a material consideration inducing Seller to convey the Property
to Buyer, Buyer has represented to Seller that it is acquiring the Property to
develop thereon the improvements (the "BUYER IMPROVEMENTS") described in the
documents listed on Exhibit "2" attached hereto and incorporated herein by this
reference, and that Buyer intends to commence construction of the Buyer
Improvements on or before the date that is three hundred sixty (360) days after
the recordation of this Agreement (plus a period of time equal to the duration
of events not within the reasonable control of Buyer) (the "CONSTRUCTION
COMMENCEMENT DEADLINE"). Buyer has further represented to Seller that Buyer
intends to complete construction of the Improvements on or before the date that
is four hundred twenty (420) days after the commencement of construction (plus a
period of time equal to the duration of events not within the reasonable control
of Buyer) ("CONSTRUCTION COMPLETION DEADLINE"). Buyer has further



                                   EXHIBIT "G"

                                  Page 1 of 13

<PAGE>

represented that it has not purchased the Property to transfer its interest
therein until after Buyer shall have commenced construction of the Buyer
Improvements on the Property.

      C.    Buyer acknowledges that Seller is engaged in master-planning the
development of that certain real property located in the City and more
particularly described in Exhibit "3" attached hereto and incorporated herein by
this reference ("TORREY HILLS"). The Property is located within Torrey Hills.
Seller agreed to sell the Property to Buyer in part in reliance on Buyer's
representation that it would develop the Buyer Improvements on the Property, and
if Buyer should fail to commence construction of the Buyer Improvements or
should transfer its interest in the Property to another investor or builder on
or before the Construction Commencement Deadline, then Seller will be
substantially and irreparably damaged.

                                A G R E E M E N T

      NOW, THEREFORE, in consideration of the foregoing and other valuable
consideration, the receipt of which is hereby acknowledged, including without
limitation the sale of the Property to Buyer, Buyer and Seller hereby agree as
follows:

      1.    Right of First Offer.

            1.1.  Grant of Right to Seller.

                  1.1.1. Except to an "END USER", defined for all purposes
herein as a third party entity with an unconditional obligation to Buyer to
occupy at least fifty percent (50%) of the office building constructed as part
of Buyer's Improvements, and who unconditionally assumes the obligations of
Buyer under this Right of First Offer Agreement, Buyer shall not transfer its
interest in the Property or any part thereof, other than to a Buyer's affiliate,
except subject to Seller's right of first offer (the "RIGHT OF FIRST OFFER") to
purchase the Property as provided herein, unless Buyer shall have first
Commenced Construction (as defined in Section 15 hereof). Buyer shall not
transfer the Property, or any portion thereof, other than as provided above
without first giving prior written notice (the "RFO NOTICE") thereof to Seller
unless Buyer shall have first Commenced Construction. The RFO Notice shall
include a summary of the terms of the proposed transfer, including without
limitation, the purchase price, method of payment and condition of title to be
transferred. Each RFO Notice shall state a purchase price in cash.

                  1.1.2. If Seller, within thirty (30) days after receipt of the
RFO Notice, indicates in writing to Buyer its agreement to purchase the Property
or portion thereof to be sold on the terms stated in the RFO Notice, Buyer shall
sell and convey the Property to Seller on the same terms and conditions as set
forth in the RFO Notice. If Seller does not notify Buyer of its intent to
exercise its Right of First Offer within such thirty (30) day period, or if
Seller gives Buyer written notification that it does not elect to exercise the
Right of First Offer, then Buyer may transfer the Property or portion thereof
free of the Right of First Offer on the same terms and conditions not
substantially more favorable than those offered to Seller as set forth in the
RFO Notice other than the cash consideration which may not be less than 95% of
the cash consideration set forth in the RFO Notice.



                                   EXHIBIT "G"

                                  Page 2 of 13
<PAGE>

                  1.1.3. If Buyer does not complete the transfer of the Property
within one hundred eighty (180) days after (i) the expiration of the
aforementioned thirty (30) day period, or (ii) such earlier date on which Seller
notifies Buyer that Seller does not wish to exercise its Right of First Offer,
or if Buyer intends to transfer the Property or a portion thereof on terms and
conditions which are changed or modified from those stated in the RFO Notice,
then the transaction or any further transaction shall be deemed a new
determination by Buyer to transfer the subject Property or portion thereof and
the prior provisions of this Agreement to provide Seller with a Right of First
Offer shall again be applicable.

                  1.1.4. The Right of First Offer shall be extinguished if and
only if (i) this Agreement terminates in accordance with Section 11 hereof or
(ii) Seller fails to exercise its right to purchase the Property within the
thirty (30) day period specified above and Buyer thereafter enters into a
binding agreement to transfer the Property on the described terms within the
one-hundred eighty (180) day period provided above, and provided the offer
presented to Seller in the RFO Notice was made in good faith. Failure by Seller
to respond to any other offer shall in no way extinguish the Right of First
Offer which shall in such case continue to burden the Property.

            1.2.  Transfer Defined. As used in this instrument, the term
"TRANSFER" shall be defined to mean any transfer, sale, lease for a term greater
than ten (10) years, or other conveyance, whether by agreement for sale or in
any other manner, but shall exclude any transfer merely as security for the
performance of an obligation and any transfer to a transferee to whom Buyer
could have assigned the Purchase Agreement pursuant to the provisions thereof.

            1.3.  Right of First Offer Exercised. Within ten (10) days after
Buyer's receipt of the RFO Exercise Notice, an escrow shall be opened at an
escrow company selected by Seller, which escrow shall have a time limit of
forty-five (45) days. Buyer shall transfer its interest in the Property through
said escrow to Seller or Seller's nominee pursuant to the terms and conditions
of the transfer as set forth in the RFO Notice. Buyer and Seller, or Seller's
nominee, shall each pay one-half (1/2) of the escrow fees; Buyer shall pay for
(i) any documentary tax stamps; (ii) if the transfer is in fee, an ALTA standard
Owner's Policy of Title Insurance issued by a title company satisfactory to
Seller or its nominee in the full amount of the purchase price showing fee title
vested in Seller or its nominee in the condition set forth in the RFO Notice;
and (iii) any additional amount that may be required to deliver title subject to
the terms and conditions set forth above, including without limitation, any
amount required to pay the indebtedness secured by a mortgage, deed of trust or
other encumbrance on the Property (in the event title is to be conveyed free and
clear of any such encumbrance) and the cost of obtaining any demand for payment
of such indebtedness and obtaining and recording the reconveyance, release or
satisfaction of any such encumbrance; and Seller or its nominee shall pay the
recording fee for any other instruments which are recorded through such escrow.

      2.    Option.

            2.1.  Grant of Option. Buyer hereby grants to Seller an option (the
"OPTION") to purchase the Property if Seller shall have not Commenced
Construction on or before the Construction Commencement Deadline. Seller or its
nominee may exercise the Option by written notice to Buyer (the "OPTION EXERCISE
NOTICE") at any time that is after the Construction



                                   EXHIBIT "G"

                                  Page 3 of 13

<PAGE>

Commencement Deadline, but not later than the earlier of: (a) sixty (60) days
after the Construction Commencement Deadline or (b) the date when Buyer shall
have Commenced Construction. The purchase price, upon exercise of the Option
shall be the Purchase Agreement Purchase Price payable in cash at the closing of
the repurchase of the Property. Seller shall have no obligation to (i) reimburse
Buyer for any taxes or maintenance charges paid by Buyer with respect to the
Property or any other sums paid by Buyer in connection with its purchase of the
Property or (ii) pay Buyer any interest on the purchase price paid by Buyer.
Upon the repurchase of the Property the Property shall be conveyed to Seller
subject only to the Permitted Encumbrances (as defined in the Purchase
Agreement) and any non-monetary encumbrances to which Seller shall have
consented (together with the Permitted Encumbrances, the "OPTION ENCUMBRANCES").

            2.2.  Exercise of Option. Within ten (10) days after Buyer's receipt
of the Option Exercise Notice, if Buyer still has not commenced construction, an
escrow shall be opened at an escrow company selected by Seller, which escrow
shall have a time limit of forty-five (45) days. Buyer shall transfer its
interest in the Subject Property through said escrow to Seller or Seller's
nominee for the Purchase Agreement Purchase Price. Buyer and Seller, or Seller's
nominee, shall each pay one-half (1/2) of the escrow fees; Buyer shall pay for
(i) any documentary tax stamps; (ii) an ALTA standard Owner's Policy of Title
Insurance issued by a title company satisfactory to Seller or its nominee in the
full amount of the Purchase Price showing fee title to the Property vested in
Seller or its nominee subject only to the Option Encumbrances, and (iii) any
additional amount that may be required to deliver title subject only to the
Option Encumbrances, including without limitation, any amount required to pay
the indebtedness secured by a mortgage, deed of trust or other encumbrance on
the Property and the cost of obtaining any demand for payment of such
indebtedness and obtaining and recording the reconveyance, release or
satisfaction of any such encumbrance; and Seller or its nominee shall pay the
recording fee for any other instruments which are recorded through such escrow.

      3.    Construction of Improvements - Covenants that Do Not Run With the
Land.

            3.1.  Soils. Buyer has made or, prior to the construction of any
improvements on the Property, will make its own tests to ascertain the amount
and extent of the present fill and/or any subsurface or soil condition upon or
in connection with the Property and Seller shall have no liability because of or
resulting from any fill or any subsurface or soil condition upon or in
connection with the Property, including without limitation subsurface geologic
or ground water conditions.

            3.2.  Approval of Buyer Improvements. The approval by Seller of
Buyer's Improvements shall not be deemed approval for architectural or
engineering design nor a representation or warranty as to the adequacy or
sufficiency of such plans and specifications or the construction contemplated
thereby for any use or purpose. By approving such plans and specifications,
Seller assumes no liability or responsibility therefor or for any defect in any
structure constructed from such plans and specifications.

<PAGE>

      4.    Construction of Improvements - Covenants that Run With the Land.

            4.1.  Compliance with Buyer Improvements. Buyer shall not construct
and shall not permit any other person to construct any improvement or
improvements on the Property unless all such improvements substantially comply
with the Buyer Improvements. Buyer shall submit to Seller any material
modifications to Buyer's Improvements (as defined on Exhibit "A"), prior to
implementing same. Seller's approval of said modifications shall not be
unreasonably withheld or delayed, so long as the modifications substantially
conform with Buyer's Improvements. Seller's approval of any such modifications
shall constitute an express condition to Seller's obligation to effect the
Closing. Seller shall cooperate reasonably with Buyer in Buyer's efforts to
obtain all required governmental approvals and permits for construction of
Buyer's Improvements.

            4.2.  Compliance with Laws. Buyer shall construct and complete any
and all improvements on the Property in compliance with all public laws,
ordinances and regulations applicable thereto and at the sole cost and expense
of the Buyer.

            4.3.  Construction of Initial Improvements. Buyer shall be under no
obligation to commence construction of the Buyer's Improvements; provided
however, that if Buyer shall have commenced construction of the Buyer's
Improvements, then Buyer shall thereafter diligently prosecute such construction
to completion with a goal of completing all of the Improvements on or before the
Construction Completion Deadline.

            4.4.  ADTs. Under the existing development entitlements for Torrey
Hills, a limited number of average daily trips ("ADTs") have been allocated to
Torrey Hills and the portion of Torrey Hills where the Property is located.
Seller shall cooperate reasonably with Buyer to effect an allocation of Seller's
ADTs to the Property consistent with Buyer's Improvements, but such Seller
allocation shall not exceed the amount required by applicable regulations to
support 103,800 square feet of office space ("BUYER'S MAXIMUM ADT ALLOCATION").
Buyer shall neither use nor seek an allocation of Seller-owned ADTs to the
Property in an amount greater than Buyer's Maximum ADT Allocation. Seller shall
have the right to allocate and control the allocation of any ADTs not allocated
to, or used by, Buyer and the Property for use in connection with the
development of the balance of Torrey Hills.

            4.5.  Subdivision Improvements. [Purposefully deleted.]

      5.    Indemnification. Buyer shall indemnify, protect, defend (with
counsel approved by Seller) and hold harmless Seller, its contractors and its
employees from and against any and all injuries, losses, liens, claims,
judgments, liabilities, costs, expenses and damages (including reasonable
attorneys' fees and court costs) sustained by or threatened against Seller, its
contractors and its employees which result from, arise out of or relate to
Buyer's development of or construction on the Property from and after the
Closing except to the extent caused by Seller's fraudulent, willful or grossly
negligent acts.

      6.    Liquidated Damages. Buyer and Seller agree that if Buyer were to
breach its obligation to convey fee title in the Property to Seller as set forth
in Subsection 1.1.2 hereof or Section 2.2 hereof, then Seller would suffer
actual and consequential damages because Seller's



                                   EXHIBIT "G"

                                  Page 5 of 13

<PAGE>

ability to develop its property located in the County of San Diego in a
coordinated fashion would be hindered and that such damages will be difficult to
compute. Therefore, if Buyer breaches its obligation to convey fee title in the
Property to Seller as set forth in Subsection 1.1.2 or Section 2.2 hereof, and
if Seller seeks a damages remedy for such breach, then Buyer shall pay
liquidated damages (the "LIQUIDATED DAMAGES") to Seller in an amount equal to
ten percent (10%) of the Purchase Agreement Purchase Price. Buyer and Seller
agree that the Liquidated Damages is a reasonable estimate of the damages Seller
would suffer as a result of a breach by Buyer of its obligation to convey fee
title in the Property to Seller. Buyer and Seller agree that this liquidated
damages provision shall not be deemed an election of remedies, and Seller shall
retain the right to seek, in lieu of Liquidated Damages, specific performance of
Buyer's obligation to convey the Property. If and to the extent any instrument,
including any deed of trust, purports to secure the obligations under this
Agreement, such instrument (i) shall not secure Buyer's obligation to convey the
Property and (ii) with respect to Buyer's obligations hereunder, shall secure
only Buyer's obligation to pay Liquidated Damages.

      7.    Assignment. Seller shall have the right to assign its interest in
this Agreement provided that Seller shall not be relieved of any of its
obligations hereunder. Any assignee shall execute and deliver to Buyer an
assumption agreement binding the assignee to all of Seller's obligations under
this Agreement and the related agreements and documents.

      8.    Release on Dedication. Any portion of the Property which is
dedicated or otherwise conveyed to and accepted by a public entity shall
automatically be released from this instrument without the payment of any
consideration to Seller. Within ten (10) days after a written request from
Buyer, Seller agrees to execute an instrument in recordable form evidencing such
release, provided that Buyer shall accompany such request for release with
evidence satisfactory to Seller that the foregoing conveyances have been or are
about to be made.

      9.    Covenants to Run with the Land. The Property shall be held,
developed, conveyed, hypothecated, encumbered, leased, rented, used and occupied
subject to the covenants, conditions, restrictions and other limitations set
forth in Sections 4.1, 4.2, 4.3 and 4.5 of this Agreement (collectively, the
"RESTRICTIONS"). The Restrictions are for the benefit of the portion of Torrey
Hills which is owned by Seller as of the date hereof (the "BENEFITTED
PROPERTY"); provided however, Seller shall have the right, within twenty-five
(25) years after the recordation hereof, by duly recorded amendments hereto to
unilaterally add to the Benefitted Property, any real property now or hereafter
owned by Seller that is contiguous to Torrey Hills. The Restrictions, and only
the Restrictions, are intended and shall be construed as covenants and
conditions running with and binding the Property and equitable servitudes upon
the Property and every part thereof. Furthermore, all and each of the
Restrictions shall be binding upon and burden all persons having or acquiring
any right, title or interest in the Property, or any part thereof, and their
successors and assigns, and shall inure to the benefit of the Benefitted
Property and the owners of the Benefitted Property, their successors and
assigns.

      10.   Termination. The Option and the Right of First Offer shall terminate
and cease to have further force or effect on the earlier to occur of (i) the
date when Buyer shall have Commenced Construction or (ii) four (4) years after
the recordation hereof. This Agreement shall terminate and cease to have any
further force or effect on the earlier to occur of (i) the date


                                  EXHIBIT "G"

                                  Page 6 of 13
<PAGE>

when Buyer shall have Completed Construction, or (ii) six (6) years after the
recordation hereof or (iii) the date provided in Section 1.1.4. Notwithstanding
the foregoing, Seller, acting alone and without the concurrence of any other
owner of any portion of the Benefitted Property, shall have the right at any
time and for any reason, but under no circumstances except as may be provided
hereunder shall Seller have any obligation, to release all or any portion of the
Property from any or all of the covenants, conditions, restrictions and other
limitations set forth in this Agreement by recordation of a duly executed
release of this Agreement, which in all events Seller shall execute and record
upon termination of this Agreement, upon Buyer's request.

      11.   Choice of Law; Attorneys' Fees. This Agreement shall be construed
and applied in accordance with the laws of the State of California. Should
either party hereto institute any action or proceeding in court or any
arbitration or similar proceeding to enforce any provision hereof or for damages
by reason of any alleged breach of any provision of this Agreement or for any
other judicial remedy, the prevailing party shall be entitled to receive from
the losing party all reasonable attorneys' fees and all court costs in
connection with said proceedings.

      12.   Assignment of Warranties and Plans. In the event the Property or any
portion thereof is transferred to Seller or its nominee hereunder, all
warranties in which Buyer may then have an interest relating to work, labor,
skill or materials furnished in connection with the construction of any
improvements on the Property or portion thereof transferred shall thereupon be
deemed (a) assigned to, and (b) the property of, Seller or its nominee without
further act or consideration. Also in the event of such transfer, all of Buyer's
rights to the plans and specifications which have been prepared by or for Buyer
related to improvements on the Property or portion thereof transferred, whether
constructed or not, shall be deemed assigned to, and the property of, Seller or
its nominee without consideration or expense to Seller or its nominee. Buyer
agrees to execute, within ten (10) days of a request by Seller or its nominee,
such documents as Seller or its nominee reasonably requests to document the
foregoing assignments.

      13.   Notices. Any notice or other communications to be given or other
documents to be delivered by any party to the other or others and any payments
from Buyer to Seller, may be delivered in person to an officer of any party, or
may be deposited in the United States mail in the City, duly certified or

Express Mail of the U. S. Postal Service or Federal Express or any other courier
guaranteeing overnight delivery, charges prepaid. Notices and other

I.    Description: The Buyer's Improvements are generally described as follows:

      a.    The construction of not more than two (2) buildings of no greater
            than 70 feet in height, measured from the pad surface level to the
            top of the building parapet; provided, however, elevator shafts and
            related equipment; heating, ventilating and air conditioning
            equipment; and satellite dishes and other communications equipment,
            all of which shall be screened, may extend to a maximum height of 78
            feet.

      b.    The use of architectural highlights at key elements of the building.

      c.    The use of tinted not reflective glazing typical throughout the
            project as dictated by the approved PID.

      d.    The limiting of the parking garages to two levels above grade.

      e.    The locating of mechanical equipment in yards located at or below
            grade.

II.   Average Daily Trips: Seller shall cooperate reasonably with Buyer to
effect an allocation of average daily trips (ADTs) to the Property consistent
with Buyer's Improvements (subject to and as defined by the term "Buyer's
Maximum ADT Allocation" in Section 1(l) of the Purchase and Sale Agreement).
Buyer shall neither use nor seek an allocation of Seller-owned ADTs to the

Seller for use in connection with the development of the balance of Torrey

III.  Approvals: Buyer shall bear responsibility for obtaining all permits,
licenses and other approvals required for the development of the Buyer's

by Seller in accordance with Section 4.2 of the Purchase and Sale Agreement.
Buyer shall bear all costs associated with any such permits, licenses and other
approvals. Prior to contacting or meeting with any governmental entity with
respect to the Property, Buyer shall give Seller reasonable advance notice of
such contact or meeting and shall let representatives of Seller attend and
participate in such contact or meeting. Prior to submitting any items (including
without limitation any applications, proposals, plans, requests or other
documents) relating to the Property or Buyer's contemplated use of the Property
to the City or any such entity, Buyer first shall obtain Seller's written
approval of such items, which shall not be unreasonably withheld or delayed, so
long as said items are in substantial conformance with subparagraph I. a. above.
Approval of a particular item shall be deemed given by Seller if Seller does not
disapprove of the item within five (5) Business Days after Buyer's delivery
thereof to Seller. Specific time periods for notices and approvals under this
Section III shall be in accordance with the Purchase and Sale Agreement.

                UNDERTAKING OF REPRESENTATIONS AND WARRANTIES AND

                              RELEASE AND AGREEMENT

      THIS UNDERTAKING OF REPRESENTATIONS, AND WARRANTIES AND RELEASE AND
AGREEMENT (this "UNDERTAKING") is made on the date set forth below by TORREY
VIEW PHASE II, L.P., a California limited partnership ("BUYER"), for the benefit
of WESTBROOK TORREY HILLS, L.P., a Delaware limited partnership ("SELLER").
Buyer represents and covenants for the benefit of Seller as follows:

      1.    The Agreement. Pursuant to that certain Commercial Land Purchase and
Sale Agreement and Joint Escrow Instructions (the "PURCHASE AGREEMENT"), dated
for reference purposes as of July 10, 2001, by and between Buyer and Seller,
Buyer has had full access to and has (to Buyer's satisfaction) inspected and
evaluated for potential purchase the Property. Buyer is executing this
Undertaking pursuant to Section 6.2 of the Purchase Agreement, effective as of
the Closing, and Seller would not sell the Property to Buyer but for Seller's
agreements hereunder. Capitalized terms used herein without definition shall
have the meaning set forth in the Purchase Agreement.

      2.    Inspection Complete. Buyer and experts of Buyer's choice have had
full access to and have (to Buyer's satisfaction):

            (a)   physically inspected the "PROPERTY", as such term is used in
the Purchase Agreement, and independently assessed its physical and
environmental condition;

            (b)   independently determined the value, marketability and
habitability of the Property and the feasibility of the use and development of
the Property for the development of Buyer's Improvements;

            (c)   independently assessed the attributes and viability of the
Improvement Plans;

            (d)   independently analyzed the effect of all permits, approvals,
laws, statutes, rules, ordinances and other governmental regulations and
requirements applicable to the Property or any of the foregoing, including, but
not limited to, permits and approvals required with respect to zoning, planning,
building and safety, fire, police, handicapped access, transportation and
environmental matters; and

            (e)   independently verified the completeness and accuracy of all
documents and information, if any, provided to Buyer by Seller and Seller's
agents and of all information deemed necessary or material by Buyer to close the
purchase of the Property.

      3.    Acquisition "AS IS". Buyer is acquiring and hereby accepts the
Property on an "AS IS, WHERE IS, WITH ALL FAULTS" basis, without any continuing
representations or warranties, oral or written, of Seller of any kind, except as
expressly set forth in Section 9 of the Purchase Agreement. Buyer represents,
acknowledges and agrees that:

                                   Page 1 of 3
<PAGE>

            (a)   Buyer's decision to purchase the Property pursuant to the
Purchase Agreement is based solely upon Buyer's own independent evaluation of
information deemed relevant to Buyer, Buyer has had an ample opportunity to
collect and assess such information, and Buyer has not relied upon any written
or oral promises, representations or inducements which have been made by Seller
or Seller's agents in connection with the Property or the Purchase Agreement;
and

            (b)   Except as set forth in the Right of First Offer, there are no
promises, representations or inducements by Seller or Seller's agents in
connection with the Property, and from and after the close of escrow under the
Purchase Agreement, Seller shall have no obligation to perform, cause to be
performed or pay for any work relating to the Property or its condition.

      4.    Release.

            (a)   Except as otherwise provided in the Purchase Agreement, Buyer
hereby absolutely and irrevocably releases Seller and its attorneys, officers,
directors, agents, servants, contractors, employees, and parent and subsidiary
corporations and predecessors in interest (collectively the "Released Parties")
from any and all claims, rights, demands, suits, causes of action, losses,
costs, obligations, liabilities and expenses of every kind or nature, known or
unknown, suspected or unsuspected, fixed or contingent, arising out of or
relating in any way to the Purchase Agreement, the relationship of Seller and
Buyer, the Property, its condition, its value, its marketability, its
habitability, its feasibility for use and development, the attributes and
viability of the Improvement Plans and the effect of any permits, approvals,
laws, statutes (including the Comprehensive Environmental Response, Compensation
and Liability Act of 1980, 42 U.S.C.A. Sections 9601 et. seq.), rules,
ordinances and other governmental regulations or requirements applicable to any
of the foregoing (including but not limited to permits and approvals required
with respect to zoning, planning, building and safety, fire, police, handicapped
access, transportation, parking and environmental matters), or any other matters
pertinent to Buyer's acquisition, ownership, use or development of the Property.

            (b)   Buyer hereby acknowledges that Buyer has not relied upon any
other representation of any kind made by Seller in making the foregoing release.

            (c)   Buyer is aware of the provisions of Section 1542 of the
California Civil Code which Section reads as follows:

            "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
            CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT
            THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM
            MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
            DEBTOR."

Buyer waives the provisions of said Section 1542 of the California Civil Code
and the provisions of any other applicable laws restricting the release of
claims which the releasing parties do not know or suspect to exist at the time
of release, which, if known, would have materially affected Buyer's decision to
agree to this release.

            (d)   It is hereby further understood and agreed that the acceptance
of delivery of this release by the parties released hereby shall not be deemed
or construed as an admission of liability of any nature whatsoever arising from
or related to the subject of the within release.

      5.    Advice of Counsel. Buyer hereby agrees, represents and warrants that
Buyer has had advice of counsel of its own choosing in negotiations relating to
the Purchase Agreement, in consummating the transactions contemplated by the
Purchase Agreement, and in delivering this Undertaking. Buyer further
acknowledges that it has read the provisions of the Purchase Agreement and this
Undertaking (including the foregoing release), that Buyer has had the legal
effect of the Purchase Agreement and this Undertaking (including the foregoing
release) fully explained by such counsel, and that Buyer is fully aware of the
contents of the Purchase Agreement and this Undertaking and of their respective
legal effect.
