to the recordation of the Final Map. Effective upon the Close of a Purchase
Escrow, Buyer shall assume and perform the obligations of the property owner
under such subdivision agreements, subdivision improvement agreements and
similar agreements as to the Phase purchased, and shall indemnify, defend and
hold Seller harmless therefrom. Buyer shall post all bonds required in
connection with the recordation of any Final Maps for portions of the Property
after the date hereof, and shall pay all premiums therefore at its sole cost.
Within sixty (60) days after the execution of this Agreement, Buyer also agrees
to substitute its own bonds for any bonds now posted by Seller in connection
with existing Final Maps on the Property. In the event of any termination of
Buyer's Option as to any portion of the Property, Seller shall within sixty (60)
days after such termination obtain a release of any bonds Buyer has posted with
respect to such portion of the Property so long as such bonds

                                      -18-
   20

do not also pertain to other real property owned by Buyer. Buyer shall not
modify the size or number of the residential lots shown on the currently
approved tentative maps for the Property without the prior written consent of
Seller, which shall not be unreasonably withheld or delayed.

               8.2. License to Enter and Construct Improvements. To facilitate
Buyer's development of the Property, Seller hereby grants Buyer a nonexclusive
license to enter upon the Property for the purpose of grading and constructing
such improvements thereto and completing such work thereon (such improvements
and work hereinafter referred to collectively as the "Improvements") as Buyer
elects to construct in connection with its planned development of the Property.
The terms of such license are further specified on Exhibit F hereto. Such
license shall terminate (i) with respect to any Phase of the Property, upon the
Close of Escrow for such Phase, or (ii) upon the termination of this Agreement.
Seller agrees to execute such documents and agreements and take such other and
further action, at no out-of-pocket cost to Seller, as are reasonably requested
by Buyer in connection with the Improvements.

               8.3. Use and Compliance with Laws.

                      (a) Use. Each Phase purchased by Buyer shall be used only
for the development, construction and occupancy of detached single-family
residential dwellings, and for incidental accessory purposes. Buyer shall not
construct, place, maintain or permit to remain on any Residential Lot more than
one detached single-family residential dwelling, except such temporary
structures as may be necessary and permitted by Law during the course of
construction of the dwelling.

                      (b) Compliance with Laws. Buyer shall comply with all Laws
in connection with its use of the Property.

               8.4. Maintenance; Completion of Residences.

                      (a) Maintenance of Property. Buyer shall maintain the
Property in a neat, attractive, sanitary and orderly condition and in compliance
with all applicable Laws. All weeds, rubbish, trash, garbage, debris and other
unsightly waste and materials shall be regularly removed from the Property and
shall not be permitted to accumulate upon the Property.

                      (b) Completion of Residences. Once Buyer has commenced the
construction of a residential structure on the Property, Buyer shall, subject to
force majeure, diligently pursue such construction to completion.

               8.5. Periodic Reports. Buyer shall deliver the following reports
to Seller at the times set forth below:

                          (i) If requested by Seller, within five (5) business
days after the close of escrow for each sale by Buyer of a Residential Lot in a
Phase purchased by Buyer, a copy of the seller's escrow settlement statement and
the sales contract for the sale; and

                                      -19-
   21

                          (ii) within twenty-five (25) days after the end of
each calendar quarter, a report of Adjusted Gross Proceeds and Net Profits
generated by Buyer during such quarter in such detail as Seller reasonably may
request with respect to Phases purchased by Buyer.

               8.6. Books and Records. Buyer shall: (i) maintain full and
complete books of account and other records reflecting, on a Unit by Unit basis,
the Adjusted Gross Proceeds and Net Profits for all Units purchased by it in
accordance with GAAP; and (ii) permit Seller and its agents, from time to time
during normal business hours and at any other reasonable tunes, to inspect and
copy all such books and records.

                    Seller shall have the right, at any time and from time to
time, to cause an audit of Buyer's books and records with respect to the Phases
purchased by it (including the examination of such federal income tax returns of
Buyer or any affiliate of Buyer as Seller may deem necessary) to be made by a
certified public account or firm of certified public accountants of nationally
recognized standing selected by Seller to verify the accuracy of the statement
of Net Profits required by this Agreement. The cost of any such audit shall be
borne by Seller unless the audit reveals a deficiency of more than two percent
(2%) in the Additional Purchase Price which should have been paid by Buyer, in
which event, Buyer shall pay to Seller, on demand, the costs of such audit plus
the amount of the deficiency, together with two percent (2%) of the amount
underpaid as a late charge.

               8.7. Real Estate Taxes and Bond Premiums. During the term of this
Agreement, Buyer shall, before delinquency, pay all real property taxes and
assessments imposed on the Property and attributable to such term. Further,
during the term of this Agreement, Buyer shall pay before delinquency all
premiums on improvement bonds or other like indemnities provided by Seller to
any Authority in connection with the Project. Seller shall give written notice
to Buyer of the amount and due dates of such items not less than thirty (30)
calendar days prior to any due date. If any item covers a period of time either
before the commencement of this Agreement or following its expiration or
termination, then, such item shall be prorated. In the event that Seller pays
any such item, then, Buyer shall reimburse Seller within thirty (30) days
following receipt of a written request for reimbursement together with such
substantiation as Buyer may reasonably request.

               8.8. Approval of Plans. Before Buyer commences the construction
of any residences on the Property, Buyer shall submit the plans and
specifications for such residences to Seller for approval. Seller shall either
approve or disapprove such plans and specifications within ten (10) days of
receipt thereof. Seller's approval shall not be unreasonably withheld. If Seller
has not approved or disapproved such plans and specifications within such ten
(10) day period, Seller shall be deemed to have waived its right to approve or
disapprove such plans and specifications. The approval by Seller of any plans
and specifications 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. By
approving any such plans and specifications, Seller assumes no liability or
responsibility therefor or for any defect in any structure constructed in
accordance with the items approved by Seller.

                                      -20-
   22

               8.9. No Homeowners' Association. Buyer hereby acknowledges that
it has no plans to form a homeowners' association for the Project. Seller's
prior written consent shall be required before Buyer forms a homeowners'
association for the Project. As a condition to granting any such consent, Seller
shall have the right to approve the form and substance of the governing
documents for such association, including any covenants, conditions and
restrictions and the respective rights granted or reserved to Buyer and Seller
thereunder.

        9.     Entry on Seller's Property.

Seller's partners and the officers, directors, shareholders, employees and
agents of Seller and/or Seller's partners shall not be liable for any loss,

        BUYER ACKNOWLEDGES THAT IT HAS BEEN ADVISED BY ITS LEGAL COUNSEL AND IS
FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH
PROVIDES 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 BEING AWARE OF SAID CODE SECTION, HEREBY EXPRESSLY WAIVES ANY
RIGHT IT MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER STATUTE OR COMMON LAW

shareholders, employees and agents of Seller and/or Seller's partners from all
loss, liability, damages, costs and expenses (including attorneys' fees) arising

made by Buyer or any other person(s). The foregoing waiver and indemnity shall
apply to any claim or action brought by a private party or by a governmental
authority under any statute or common law now or hereinafter in effect and is
intended to apply with respect to loss, damage, injury or claim arising before
or after the conveyance of all of the residences

                                      -22-
   24

constructed on the Project. With respect to design, construction methods,

its approval or recommendation, the foregoing waiver and indemnity shall apply
irrespective of Seller approval or recommendation.

                      (c) Without limiting the generality of Subsection 10(b)
above, Buyer agrees to indemnify and protect Seller, and to defend Seller with
counsel reasonably acceptable to Seller, against any and all claims, demands,
liabilities, obligations, damages, causes of action, judgments, losses, costs
and expenses (including, without limitation, reasonable attorneys' fees) which
Seller may incur or suffer by reason of or in connection with (i) any breach of
or failure of Buyer to perform any of its Obligations contained in this
Agreement, and (ii) the development or disposal by Buyer of the Property
(including, without limitation, the construction of residential dwellings and
the sale or lease of such dwellings to the public or any Person). The
obligations of Buyer set forth in Section shall survive any termination of this
Agreement and the close of any Purchase Escrow.

                      (d) Notwithstanding the provisions of this Section 10
above, Buyer shall be relieved from liability for, and the waivers and
indemnities set forth in subsections (a), (b) and (c) above shall not apply to
the extent of, any loss, damage, liability, injury or claim to the extent the
same is found by reference of controversies under subsection 13.15, below, or by
a court of competent jurisdiction to have been caused solely by the gross
negligence and/or willful misconduct of Seller.

                      (e) Nothing in this Section 10 shall relieve Seller from
any liability for breach of any of Seller's representations or warranties under
Section 6 above.

Buyer receives written notice from Seller that such proposed Phasing schedule

this Agreement on its part to be performed if the failure should continue
uncured for a period of thirty (30) days after written notice is given to the
party of the occurrence of the failure; provided, however, that the failure
shall not be deemed to have occurred if the failure relates to a Purchase Escrow
and is of a nature that reasonably requires more than thirty (30) days to cure,
is capable of being cured fully before the close of the Purchase Escrow and the
party is proceeding continuously and diligently to cure the failure and does
cure the failure before close of the Purchase Escrow;

                                      -23-
   25

the thirty (30) day period); or

                      (h) The attachment, execution or other judicial seizure of
the party's interest in this Agreement (and, in the case of Seller, in the
Property), such attachment, execution or seizure being in an amount not less
than Fifty Thousand Dollars ($50,000) and remaining undismissed or undischarged
for a period of thirty (30) days after the levy of the attachment, execution or
seizure (or to the date of the next close of a Purchase Escrow if such date
occurs before the expiration of the thirty (30) day period).

               11.2. Default by Buyer. If Buyer shall materially Default under
any of the terms of this Agreement, Seller shall have the right, in addition to
any other rights or remedies which it may have at law or in equity, to terminate

Agreement by giving written notice of such termination to Seller and Escrow
Holder, and shall also have all other rights and remedies available at law or in
equity, including without limitation an action for specific performance or for
monetary damages. Upon the giving of such a notice of termination, this
Agreement (excluding unclosed Purchase Escrows), and the rights and obligations
of Buyer and Seller under this Agreement shall terminate.

        12.    Indemnification.

               12.1. Indemnification of Seller. Buyer agrees to indemnify, hold
harmless and protect Seller, and to defend Seller with counsel reasonably
acceptable to Seller, against any and all claims, demands, liabilities,
obligations, damages, causes of action, judgments, losses, costs and expenses

               13.11. Construction. Whenever the context of this Agreement
requires the same, the singular shall include the plural and the masculine,

other party under this Agreement shall be implied from any omission or delay by
the nondefaulting party to take action on account of the Default if the Default
persists or is repeated. Any waiver of any covenant, term or condition contained
in this Agreement must be in writing. Any such express written waiver shall not
be construed as a waiver of any subsequent breach of the same covenant, term or
condition, nor shall it affect any Default other than the Default expressly made
the subject of the waiver. Any such express waiver shall be operative only for
the time and to the extent stated in the waiver. The consent or approval by a
party to or of any act by the other party shall not be deemed to waive or render
unnecessary consent or approval to or of any subsequent act.

joint venturer, trustee, fiduciary, alter ego, manager, controlling person or
other business associate or participant of any kind of the other party or any of
its Affiliates.

               13.14. Third Parties Not Benefited. This Agreement is made for

               13.15. Reference of Controversies. Any controversy between Seller
and Buyer under this Agreement which is the subject of an action or proceeding
brought by either Seller or Buyer shall be referred to a referee in accordance
with the provisions of Chapter 6 ("Chapter 6"), Title 8, Part II of California
Code of Civil Procedure ("Code"), (Sections 638 et seq.) as follows:

                      (a) Seller and Buyer shall submit to the appropriate court
a stipulation ("Stipulation") for a general order of reference to include all
issues in the action or proceeding, whether of fact or of law, including all
issues raised as affirmative defenses or cross-claims. If one party refuses or
fails to join in the submission of a Stipulation within fifteen (15) days after
being requested in writing to do so by the other party, the other party may make
a motion ("Motion") to the appropriate court for a general order of reference,
which the party failing to stipulate shall not oppose.

                      (b) Not later than ten (10) days after the filing of the
Stipulation, Buyer and Seller shall use their best efforts to agree on the
appointment of a Person to act as referee; provided, however, if a Motion is
made because one party fails or refuses to join in the submission of the
Stipulation, the party making the Motion may select, not later than ten (10)
days after the making of the Motion, any Person as the referee so long as the
Person selected does not have any business or social relationship with either
Seller or Buyer and is a judge or retired judge of the Superior Courts of the
State of California or a justice or retired justice of any appellate court of
the State of California. Any such selection shall be subject to the provisions
of Section 641 of the Code.

                      (c) If a referee is not selected in accordance with the
preceding subsection, or if the Person selected is not willing to act as
referee, a single referee shall be chosen in the manner set forth in Sections
640 and 641 of the Code. The referee must be a judge or retired judge of the
Superior Courts of the State of California or a justice or retired justice of
any appellate court of the State of California.

                      (d) Seller and Buyer expressly waive any right to a trial
by jury.

                      (e) A reporter shall be present at all proceedings before
the referee.

                      (f) If the reference is commenced by a Stipulation, each
party shall bear its own costs in connection with the reference (including
attorneys' fees) and one half of the referee's fees and reporter's fees. If the
reference is commenced by a Motion, the party against whom judgment is entered
shall bear all costs in connection with the reference (including, without
limitation, reasonable attorneys' fees and the referee's fees and reporters
fees).

                      (g) The referee shall apply all California roles of
procedure and evidence and shall apply the substantive laws of California in
deciding any and all issues submitted to the referee.

                      (h) The referee shall have the authority to hear law and
motion matters.

                                      -28-
   30

                      (i) All discovery which either of the parties may wish to
take shall be commenced within thirty (30) days and completed within sixty (60)
days after the reference is ordered in accordance with Section 638 of the Code.

                      (j) Section 998 of the Code shall be applicable under the
reference.

                      (k) The referee's findings and decision under Section 643
and 644 of the Code shall be final and binding on Seller and Buyer and shall not
be subject to appeal or review.

                      (l) Seller and Buyer desire to have any and all matters
referred to a referee determined as soon as practicable consistent with the
availability of the referee, counsel and witnesses.

                      (m) Seller and Buyer agree that neither party will be
permitted to defeat the provisions of this subsection 13.15 by including
non-parties to this Agreement as parties to the action or proceeding. If
nonparties to the Agreement are proper parties to the action or proceeding:

                          (i) The non-parties to the Agreement may, at their
sole option, elect to stipulate to the reference and comply with the terms of
this subsection 13.15.

                          (ii) If the non-parties do not so agree, Seller and
Buyer shall stipulate that all claims by and against the non-parties be severed
and determined separately.

                          (iii) The provisions of this subsection 13.15 shall
have no further force or effect in the event Chapter 6 is repealed or amended in
such a manner as to make it materially inconsistent with the provisions of this
subsection.

               13.16. Force Majeure. If Buyer is delayed at any time in the
performance of its obligations hereunder (other than any obligation which only
requires the payment of money), by reason or labor disputes, fire, governmental
moratoria, adverse weather conditions or other "acts of God" not reasonably
anticipatable, unavoidable casualties, or any causes beyond the Buyer's
reasonable control, then the time for such performance shall be extended for
such reasonable time as may compensate for such occurrences. Buyer's inability
to obtain financing will not be deemed to constitute an event of force majeure
in any event.

               13.17. Assignment on Termination. If this Agreement terminates
prior to Buyer's exercise of all the Options, Buyer shall assign to Seller (on a
non-exclusive basis to the extent possible) any and all entitlements,
development agreement rights and other intangible rights then owned by Buyer and
that relate to the development of the unpurchased portions of the Project.
Notwithstanding the foregoing, Buyer shall have no obligation pursuant to this
subsection 13.17 to assign to Seller any of Buyer's plans, specifications or
other architectural work product with respect to residences planned for the
Property.

                                      -29-

exclusion to be effective as to any such Phase from and after the date the same
is transferred to Buyer. Notwithstanding anything herein to the contrary, other
than with Seller's prior consent, Buyer shall not construct any residential
houses on any Residential Lot that Buyer has not yet acquired title to pursuant
to this Agreement.

        2. Term. The term of the license shall commence upon the execution of
this Agreement by both Seller and Buyer. The license shall terminate (i) with
respect to any Phase of the Property, upon the Close of Escrow for such Phase,
or (ii) upon the termination of this Agreement.

        3. Hazardous Materials. During the term of this license, Buyer shall not
introduce or release any Hazardous Materials in, to, from, under or on the
Property, or bring any Hazardous Materials onto or across the Property, except
as necessary to complete the Work and then only so long as the same are used,
handled and disposed of in accordance with applicable Laws. If Buyer becomes
aware of the presence of any Hazardous Materials on the Property, it shall
immediately notify Seller in writing of the same.

        4. Maintenance of Property; Performance of Work; Alterations.

               (a) Buyer shall not, except as required to complete the Work,
alter the physical condition of the Property. During the term of this license,
Buyer shall, at its sole cost, expense and liability, maintain in a safe and
sanitary condition those portions of the Property on which it is performing the
Work or which it is otherwise using. Without limiting the foregoing, Buyer shall
maintain any construction routes in a clean condition and establish and maintain
a regular dust control program. Buyer shall be responsible for any damage done
to the Property or other property of Seller and for any theft of Seller's
property from the Property or other real property of Seller by Buyer or its
representatives.

               (b) Buyer shall bear all costs of the Work. Buyer shall obtain at
its cost all permits and approvals required in connection with the Work
(including without limitation

   49

those required hereunder from Seller and also any required by any Authorities
with jurisdiction thereover) and shall comply with the requirements of all
Authorities with jurisdiction thereover, including without limitation all
requirements as to noise control, construction traffic and other construction
matters. If required by Seller, any equipment or materials placed or stored on
the Property by Buyer or its representatives shall be placed or stored only in
locations specifically approved by Seller. If required by Seller, any access by
Buyer and its representatives onto, over or across the Property shall be by way
of roads, paths or access points designated by Seller. Upon termination of this
license, Buyer shall remove any equipment or materials stored on the Property
and shall repair and restore every portion of the Property damaged or disturbed
during the term of this license to at least as good condition as existed prior
to Buyer's entry onto the Property; provided, however, Seller shall have the
option to do any necessary repairs and restoration and Buyer shall pay Seller
any and all amounts expended therefore upon demand. Buyer agrees to pay or
reimburse Seller for any utility or water charges allocable to Buyer's use of
the Property.

               (c) Buyer shall not use the Property in any manner or conduct any
activities thereon which will interfere with or delay Seller's use or
development of the Property. No Improvements (whether or not a part of the Work)
shall be constructed or installed on the Property until the plans and
specifications therefor have been approved by Seller. Seller's approval right
shall include, without limitation, the right to approve the architectural style
and exterior colors and materials of any structure, as well as landscaping plans
and the exact location of any such structure. All Improvements shall be
completed only in accordance with the approved plans and specifications
therefore, and in a good and workmanlike manner. Upon termination of this
license without an acquisition of the Property by Buyer, all improvements made
by Buyer upon any portion of the Property shall become the sole property of
Seller, without the payment of any consideration to Buyer.

        5. Seller Not Liable. All persons who enter onto the Property pursuant
to this license do so at their own risk, and shall comply with all necessary and
reasonable instructions and directions of Seller with respect to use of the
Property. As a material part of the consideration for this license and the
Agreement, Buyer hereby waives and agrees to indemnify, protect, defend and hold
Seller harmless from and against any loss, damage, injury, accident, fire or
other casualty, liability, claim, cost or expense (including but not limited to
actual attorneys' fees) of any kind or character to any person or property
arising from, caused by or related to (i) any use of the Property by Buyer or
its representatives, (ii) any act or omission of Buyer or any of its
representatives, (iii) any bodily injury, property damage, accident, fire or
other casualty on the Property caused by the entry or activities of Buyer or its
representatives, (iv) any violation or alleged violation by Buyer or its
representatives of any law, ordinance or regulation now or hereafter enacted,
(v) any failure of Buyer to maintain the Property in a safe, decent, and
sanitary condition, (vi) the breach or violation of the terms of this license by
Buyer, (vii) any statutory liens for labor or materials or other liens which may
arise out of the Work or Buyer's activities on the Property, and (viii) any
enforcement by Seller of any provision of this license and any costs of duly
removing Buyer from the Property or restoring the same as provided herein. Buyer
acknowledges and agrees that Seller has no responsibility for loss of any
property of Buyer
   50

by theft, and Seller has no obligation to provide any security in respect of
Buyer's property. The provisions of this Paragraph 5 shall survive any
termination of this license.

        6. Insurance. Prior to and at all times after initially entering upon
the Property for any purpose, Buyer shall at its expense maintain with a
reputable company or companies qualified to do business in California and
acceptable to Seller, a policy or policies of comprehensive or commercial
general liability insurance with respect to the Property and the operations and
activities of or on behalf of Buyer on or about the Property, including, but not
limited to, owned, rented and non-owned automobile (vehicle) liability, personal
injury, blanket contractual, broad form property damage, products liability,
manufacturer's and contractor's basic coverage with X, C and U exclusions
deleted, owners' and contractors' protective liability and products/completed
operations liability coverage. Such policy shall provide that its coverage is
primary to any insurance of Seller (whose insurance shall be excess and
noncontributing) and shall contain a provision stating that the naming of an
additional insured shall not negate any right the additional insured would have
had as a claimant under the policy if not so named. Such policy shall contain
severability of interest and cross liability clauses. Such policy or policies
shall have limits of liability of not less than Ten Million Dollars
($10,000,000) combined single limit per occurrence. The policy shall provide
that it is not cancelable without thirty (30) days prior written notice to
Seller. Seller shall be named as an additional insured on such policy or
policies, and a certificate or certificates of insurance evidencing such policy
or policies shall be delivered to Seller before Buyer's initial entry onto the
Property. Additional certificates evidencing renewal or replacement of such
policy or policies shall be delivered to Seller at least thirty (30) days prior
to the expiration of any such policy or policies. A copy of any such policy
shall also be delivered to Seller upon request. Seller also reserves the right
to require Buyer to maintain a standard "all risk" Builders Risk Policy during
any period of construction for not less than the full replacement cost of the
improvements, which shall include a replacement cost endorsement and otherwise
be in form and substance acceptable to Seller. Buyer shall also maintain workers
compensation insurance as required by law.

        7. Liens. Buyer shall not suffer or permit to be filed or enforced
against the Property, or any part thereof, any statutory lien for labor or
materials (including without limitation any mechanics' or materialmen's lien) or
any claim for damages arising from or out of Buyer's use of or activities on the
Property. Buyer shall pay or cause to be paid on a timely basis all bills or
claims which could give rise to any such statutory lien or claim for damages. If
any statutory or other lien is filed or asserted against the Property, Buyer
shall cause the same to be fully discharged, by payment, bonding or otherwise,
within twenty (20) days of such filing or assertion, and upon any failure of
Buyer to do so, Seller shall have the right to do so, by payment, bonding
(including without limitation obtaining and recording a lien release bond
pursuant to California Civil Code Section 3143) or otherwise and Buyer shall pay
Seller on demand all amounts expended in connection with obtaining such release
or discharge. Buyer shall notify Seller no less than five (5) days prior to
doing any Work on the Property in order to allow Seller to post and record, at
Seller's option, appropriate notices of nonresponsibility. The failure by Seller
to post or record such notices shall not affect or negate in any manner Buyer's
obligations under this license.
