                        UDC HOMES, INC. AND SUBSIDIARIES
              CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.   BASIS OF PRESENTATION

         The  consolidated  financial  statements  include  the  accounts of UDC
     Homes, Inc. (the "Company") and all of its majority-owned  subsidiaries and
     joint ventures.  All material  intercompany  balances and transactions have
     been  eliminated in  consolidation.  Investments  in  unconsolidated  joint
     ventures are recorded using the equity method of accounting.

         The  consolidated   financial  statements  and  related  notes  thereto
     contained  in the  Annual  Report on Form 10-K for the  fiscal  year  ended
     September 30, 1997,  filed by the Company with the  Securities and Exchange
     Commission, should be read in conjunction with these consolidated financial
     statements. The results of operations for the interim periods presented are
     not  necessarily  indicative  of the results to be expected  for the entire
     year.  Certain amounts in the  consolidated  financial  statements of prior
     periods have been reclassified to conform to the current presentation.  The
     consolidated  financial statements included herein are unaudited;  however,
     they include all  adjustments of a normal  recurring  nature which,  in the
     opinion of  management,  are necessary to present  fairly the  consolidated
     financial  position,  results of operations  and cash flows for the interim
     period.

         Through May 31, 1997, the Company's  mortgage  banking  operations were
     exclusively conducted through its indirect,  wholly-owned  subsidiary,  UDC
     Mortgage  Corporation ("UDC Mortgage  Corp.").  Effective June 1, 1997, the
     Company entered into a joint venture with Norwest Ventures,  Inc. (entitled
     UDC Mortgage)  through which all future mortgage banking  operations of the
     Company will be conducted.  The joint venture  agreement  provides that all
     capital contributions and distributions, as well as all profits and losses,
     will be split 50/50.  The  Company's  investment  in this joint  venture is
     being  accounted for using the equity method of  accounting.  The Company's
     investment was approximately $50,000 at December 31, 1997 and September 30,
     1997,  and is included in "Other assets" in the  accompanying  consolidated
     balance  sheets.  For the quarter ended December 31, 1997,  income from all
     mortgage operations was $382,000,  of which $281,000 was from the Company's
     equity in the operations of UDC Mortgage and $101,000 was from UDC Mortgage
     Corp.   Effective   December  31,  1997,  UDC  Mortgage  Corp.  ceased  all
     operations.

         In December  1997, the Company  entered into a joint venture  agreement
     with SunPower  Properties L.L.C. (of which an affiliate of DMB, a holder of
     50% of the Company's  common stock,  is a member) for the  development of a
     master-planned  retirement  community  in Arizona.  This new  community  is
     expected to consist of approximately  2,000 homesites upon completion.  The
     joint venture agreement  provides that all capital or land contributions as
     well as all  capital  distributions  and  profits  and losses be  allocated
     50/50.  The joint venture is being accounted for using the equity method of
     accounting.   At  December  31,  1997,   the   Company's   investment   was
     approximately   $835,000   and  is  included  in  "Other   assets"  in  the
     accompanying consolidated balance sheet.

3.   INTEREST

         Interest  incurred is capitalized and expensed  through cost of housing
     sales,  as they relate to housing and land  inventories.  The components of
     interest,  excluding  interest on the Company's  subordinated notes payable
     for the three months ended December 31 are as follows :

</TABLE>

         The credit facilities listed above contain numerous financial and other
     covenants  which may,  among other things,  limit the Company's  ability to
     obtain  additional  financing  when needed and on terms  acceptable  to the
     Company.  The Series B senior notes further  require the Company to make an
     offer to  repurchase  the  Series B senior  notes  with the  proceeds  from
     qualifying asset sales in excess of certain  thresholds,  as defined in the
     indenture.  In December  1997,  the proceeds from such asset sales exceeded
     the defined threshold.  Accordingly,  on January 21, 1998, the Company made
     an offer to purchase the  outstanding $10 million  principal  amount of the
     Series B senior notes at par value,  plus accrued and unpaid interest.  The
     offer to  purchase  will  expire on March 5, 1998,  unless  extended by the
     Company.

         The  payment of  interest  in cash on the  Series C and D  subordinated
     notes  is  restricted  by  certain   covenants  in  the  Company's   credit
     facilities.  The November 1, 1997 payments of interest were paid in kind in
     additional Series C and D subordinated notes.

5.   ACCRUED LIABILITIES AND EXPENSES

     Accrued liabilities and expenses consist of the following:

6.   RELATED PARTY TRANSACTIONS

     The  Company  has  entered  into  option  agreements  with DC Ranch LLC, an
affiliate of DMB, and DMB/AEW Land Holdings Two, LLC ("Land  Holdings  Two"), an
affiliate of DMB and AEW, a holder of 50% of the Company's common stock, for the
purchase  of up to 1,357 lots in southern  California  and  Arizona.  During the
quarter ended December 31, 1997, the Company paid these entities  $1,527,000 for
the purchase of 23 lots under these option agreements.  As of December 31, 1997,
the number of lots  remaining to be acquired  under these option  agreements was
1,184.

     The Company's Los Angeles regional office is located in a building owned by
an affiliate of AEW.  During the quarter  ended  December 31, 1997,  the Company
paid this affiliate $45,000 in office rent.

     The Company believes that the monetary and other provisions under the above
agreements  are no less  favorable  than could be obtained  through  third party
arrangements.

7.   CONTINGENCIES

     During 1995,  three  lawsuits were filed on behalf of a purported  class of
present and former  shareholders  of the Company against certain former officers
and directors of the Company  alleging  violation of securities  laws, fraud and
negligence. The Company is not a named defendant in these lawsuits; however, the
Company could be required to indemnify  certain  director/officer  defendants if
such defendants  incur defense expenses and seek  indemnification.  An agreement
(the  "Settlement  Agreement")  was  previously  reached  pursuant  to which the
plaintiffs and the  director/officer  defendants agreed to settle and compromise
the lawsuits in their entirety,  as such actions relate to the  director/officer
defendants and the Company, in exchange for, among other things, $12.75 million.
Of such amount, $1.5 million,  which represents the self-insured retention under
the Company's applicable  directors' and officers' insurance policies,  has been
paid by the Company.  In addition,  the Company paid  $250,000 on behalf of DMB.
Certain issuers of the Company's  directors' and officers'  insurance  policies,
together with the Company's insurance carriers,  have agreed to fund the balance
of the settlement.  The Company does not believe that its remaining  obligations
to directors  and officers will exceed its insurance  coverage.  The  Settlement
Agreement  and  amendments  thereto were approved by the  bankruptcy  court at a
final  settlement  hearing held on February 14,  1997.  The court's  decision is
currently being appealed by the Company's former independent public accountants.

     The  Company is a defendant  in lawsuits  that arise from or are related to
the conduct of the  Company's  business.  The Company  does not believe that the
ultimate  resolution  of  these  cases  will  materially  affect  the  financial
position, results of operations or cash flows of the Company.

<PAGE>
     The  increase  in volume in the Family  Division  resulted  from  increased
deliveries in California  due to an increase in the average  number of homesites
available  for sale for the quarter  ended  December 31,  1997,  compared to the
quarter ended December 31, 1996. The decrease in volume in the California region
of the Retirement  Division for the quarter ended December 31, 1997, compared to
the quarter ended December 31, 1996,  resulted from a decrease in backlog caused
by the closeout of six  communities  in California in the six month period ended
September 30, 1997.

     Net orders  represent  the  aggregate  dollar value and number of homes for
which the Company has received  purchase  deposits  and signed  sales  contracts
during the period,  net of  cancellations.  Net orders  increased in the quarter
ended  December  31,  1997,  compared to the quarter  ended  December  31, 1996,
primarily as a result of increased orders in the California region of the Family
Division  caused by an increase in the number of homesites  available  for sale.
This increase was offset by decreased orders in the Arizona region of the Family
Division as well as decreased orders in the California  region of the Retirement
Division.  The decrease in orders in the Arizona  region of the Family  Division
resulted  from a decrease in the number of  homesites  available  for sale.  The
decrease in the  California  region of the  Retirement  Division  resulted  from
                                       11

delays in the commencement of land development  activities in five  subdivisions
consisting of 506 homesites  caused by the decision to redesign  certain product
offerings and delays in obtaining certain required approvals. The approvals were
obtained in the fourth quarter of fiscal 1997.

Net Sales Backlog

     Net sales backlog represents the aggregate dollar value and number of homes
ordered,  net of  cancellations,  pending delivery at December 31, for which the
Company had received purchase deposits and signed sales contracts. The following
table presents comparative net sales backlog by market and region as of December
31:

     The  increase  in the  aggregate  dollar  value and the  number of homes in
backlog at December 31, 1997,  compared to December 31, 1996, resulted primarily
from lower levels of deliveries in the fourth quarter of fiscal 1997 compared to
the fourth quarter of fiscal 1996 in the Arizona region of the Family  Division.
The decrease in the units and dollars in backlog at December 31, 1997,  compared
to December  31,  1996,  in the  California  region of the  Retirement  Division
resulted from decreased product  availability  caused by the delays in obtaining
certain approvals as previously discussed.

</TABLE>

    Gross margins increased during the quarter ended December 31, 1997, compared
to the  quarter  ended  December  31,  1996,  primarily  due to  reduced  direct
construction costs incurred as a result of more competitive bids on construction
contracts and lower levels of change orders. Additionally, margins were lower in
the quarter ended December 31, 1996,  compared to the quarter ended December 31,
1997, due to the amortization of  approximately  $.4 million of purchased profit
which was  recorded as a result of the  acquisition  of the Company by DMB.  The
purchased profit was fully amortized as of September 30, 1997.

    The following  table presents the  components of selling and  administrative
expenses in dollars and as a percentage  of revenues  from housing sales for the
quarters ended December 31:

     The variable  component  of selling and  administrative  expenses  includes
sales   commissions,   advertising,   model   maintenance  and  model  furniture
amortization.  Variable selling and  administrative  expenses as a percentage of
revenues  from housing  sales for the quarter  ended  December 31, 1997 remained
consistent with the quarter ended December 31, 1996.

     The fixed  component of selling and  administrative  expenses  includes all
other  selling and  administrative  expenses  which  generally  do not vary with
housing sales volume. Fixed selling and administrative  expenses as a percentage
of revenues from housing sales decreased in the quarter ended December 31, 1997,
compared to the quarter ended  December 31, 1996,  primarily due to decreases in
warranty  and  settlement  costs  as well as  decreases  in  professional  fees,
including fees paid to architects, professional search firms and attorneys.

     The  Company  capitalizes  certain  interest  costs  for its home  building
operations and includes such capitalized  interest in cost of housing sales when
the related units are delivered.  Total interest  incurred by the Company's home
building  operations,  excluding interest expense on the Company's  subordinated
notes payable,  for the quarters ended December 31, 1997 and 1996 was $4,491,000
and $4,563,000,  respectively. Interest, net for the quarters ended December 31,
1997 and 1996, was $668,000 and  $2,176,000,  respectively.  Interest  incurred,
excluding  interest  expense  on  the  Company's   subordinated  notes  payable,
decreased in the quarter  ended  December 31, 1997 compared to the quarter ended
December  31,  1996 as a result of lower  average  debt  levels.  Interest,  net
decreased in the quarter  ended  December 31, 1997 compared to the quarter ended
December  31, 1996 due to increased  development  activities  which  resulted in
higher  levels of interest  capitalization.  Interest  expense on the  Company's
subordinated  notes  payable  increased  from  $1,594,000  for the quarter ended
December 31, 1996 to $3,408,000  for the quarter ended  December 31, 1997 due to
higher levels of subordinated indebtedness.

Mortgage Operations

     Through May 31,  1997,  the  Company's  mortgage  banking  operations  were
exclusively  conducted  through  its  indirect,   wholly-owned  subsidiary,  UDC
Mortgage Corporation ("UDC Mortgage Corp."). Effective June 1, 1997, the Company
entered into a joint venture with Norwest Ventures, Inc. (entitled UDC Mortgage)
through  which all future  mortgage  banking  operations  of the Company will be
conducted.  The joint venture agreement provides that all capital  contributions
and distributions,  as well as all profits and losses,  will be split 50/50. The
Company's  investment  in this joint  venture is being  accounted  for using the
equity method of accounting.  At December 31, 1997, the Company's investment was
approximately  $50,000. For the quarter ended December 31, 1997, income from all
mortgage  operations  was  $382,000,  of which  $281,000 was from the  Company's
equity in the  operations  of UDC  Mortgage  and  $101,000 was from UDC Mortgage
Corp. Effective December 31, 1997, UDC Mortgage Corp. ceased all operations.

     The Company has entered into land option  agreements with certain  entities
(including  affiliates of DMB and AEW) which have available  sources of capital.
These  entities  acquire  land and grant  purchase  options to the  Company.  At
December  31,  1997,  the  Company had land option  agreements  with  affiliated
entities which enable the Company to purchase up to 1,184 lots. The Company also
had an option  agreement  with an unrelated  party which  enables the Company to
purchase  up to 83 lots.  The  Company  believes  that the  monetary  and  other
provisions  under the agreements with affiliated  entities are no less favorable
than could be obtained through third party arrangements. The Company is actively
pursuing  the  acquisition  of land to maintain or  increase  its lot  inventory
levels in each of its operating  divisions.  There can be no assurance  that the
Company will be successful in acquiring land on acceptable  terms or in a timely
manner.

     Since May 6, 1996, the Company's  Westbrook  Village  operations  have been
conducted under a joint venture agreement in which UDC and affiliates of DMB and
AEW currently own 77.0%, 11.5% and 11.5% equity interests, respectively.

     In December 1997, the Company  entered into a joint venture  agreement with
SunPower  Properties  L.L.C.  (of which an affiliate of DMB is a member) for the
development  of a  master-planned  retirement  community  in  Arizona.  This new
community  is  expected  to  consist  of  approximately   2,000  homesites  upon
completion.  The joint  venture  agreement  provides  that all  capital  or land
contributions,  as well as all capital  distributions and profits and losses, be
allocated  50/50.  The joint  venture  is being  accounted  for using the equity
method of accounting.

Liquidity and Capital Resources

     The Company's  financing  needs depend  primarily upon sales volume,  asset
turnover,  land acquisitions and inventory  balances.  The Company has financed,
and expects to continue to  finance,  its working  capital  needs as well as its
land acquisition and construction costs through funds provided primarily by cash
flow from  operations,  current and future  borrowings  as  permitted  under the
Company's loan agreements and capital  contributions by AEW and DMB. The Company
believes that amounts  generated  from  operations,  additional  borrowings  and
capital  contributions  will provide funds adequate to finance its  homebuilding
activities  and meet its debt  service  requirements.  The  Company  continually
monitors  its current  and  long-term  cash flow  requirements  to evaluate  the
optimal use of its available financing sources.

     The Company's net cash used in operating  activities  decreased  from $19.0
million  for the quarter  ended  December  31,  1996,  to $14.4  million for the
quarter ended  December 31, 1997.  This decrease was primarily due to a decrease
in  certain  accrued  liabilities  offset  by an  increase  in land and  housing
inventory. Net cash used in investing activities increased from $0.8 million for
the quarter  ended  December  31, 1996,  to $0.9  million for the quarter  ended
December 31, 1997. This increase was due to the Company's  investment in a joint
venture for a  master-planned  retirement  community  offset by lower  levels of
computer and  equipment  purchases in the current  year.  The Company's net cash
provided by financing  activities  decreased  from $19.0 million for the quarter
ended  December 31, 1996, to $11.1  million for the quarter  ended  December 31,
1997.  This  decrease  resulted  primarily  from the  receipt of $10  million in
capital contributions in the quarter ended December 31, 1996.

     At December 31,  1997,  the Company had cash and cash  equivalents  of $4.7
million and availability of $20.4 million to be drawn under its revolving credit
facility.  At December 31, 1997,  the Company had total  indebtedness  of $243.5
million,  including  $70.0  million of senior  unsecured  notes  payable,  $98.5
million of  subordinated  notes  payable,  $69.6 million due under the Company's
$170 million revolving credit facility,  $3.6 million due under construction and
acquisition  and  development  lines of credit and $1.8  million due under other
notes payable.

     The credit  facilities  listed above contain  numerous  financial and other
covenants which may, among other things,  limit the Company's  ability to obtain
additional  financing  when needed and on terms  acceptable to the Company.  The
Company's  Series B senior notes further require the Company to make an offer to
repurchase  the Series B senior notes with the proceeds  from  qualifying  asset
sales in excess of certain thresholds,  as defined in the indenture. In December
1997,  the  proceeds  from such asset  sales  exceeded  the  defined  threshold.
Accordingly,  on January 21,  1998,  the Company  made an offer to purchase  the
outstanding $10 million  principal amount of Series B senior notes at par value,
plus accrued and unpaid  interest.  Funds  required to  repurchase  the tendered
Series  B  senior  notes,  if any,  will be  obtained  through  cash  flow  from
operations and or borrowings as permitted  under the Company's loan  agreements.
The offer to  purchase  will  expire on March 5, 1998,  unless  extended  by the
Company.

     The payment of interest in cash on the subordinated  notes is restricted by
certain  covenants  in the  Company's  credit  facilities.  The November 1, 1997
payments of interest were paid in kind in additional subordinated notes.

         The Company finances its home building and land development  operations
with a $170 million (the "commitment  amount")  revolving credit facility with a
group of banks (the "credit  facility").  The credit  facility is available  for
both construction and acquisition and development  ("A&D") activities in Arizona
and California. The amount available for A&D activities is limited to the lesser
of (a)  37.5% of the  commitment  amount or (b)  $63,750,000,  as  adjusted  for
various  sublimits,  as defined.  The credit facility  accrues interest at prime
plus 1% or, at the Company's  option,  LIBOR plus 3.25%,  payable  monthly,  and
requires a commitment  fee of 1% per annum of the commitment  amount,  an unused
commitment fee of .25% per annum of the average unused  commitment  amount,  and
syndication and agency fees. The interest rate and commitment fee may be reduced
if the Company meets certain financial ratios. The credit facility is secured by
portions of the  Company's  housing and land  inventory and matures on September
30, 1999. At December 31, 1997,  $69.6 million was outstanding and an additional
$20.4 million was available under the credit facility.

     The  Company  has  entered  into  option  agreements  with DC Ranch LLC, an
affiliate of DMB, and DMB/AEW Land Holdings Two, LLC ("Land  Holdings  Two"), an
affiliate  of DMB and AEW,  for the  purchase  of up to 1,357  lots in  southern
California and Arizona.  During the quarter ended December 31, 1997, the Company
paid these  entities  $1,527,000  for the purchase of 23 lots under these option
agreements. As of December 31, 1997, the number of lots remaining to be acquired
under these option agreements was 1,184.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings
- -------  -----------------


     The Arizona  Actions - On June 5, 1995, June 14, 1995 and October 25, 1995,
lawsuits  were  filed on behalf  of a  purported  class of  present  and  former
shareholders of the Company in the Superior Court of the State of Arizona in and
for Maricopa County (the "Court") against, among others, certain former officers
and  directors  of the Company  (the  "Director/Officer  Defendants"),  entitled
Michael A. Isco v.  Richard C.  Kraemer,  et al. (Case No. CV  95-08941),  Larry
Alexander  et al. v. Arthur  Andersen  LLP, et al. (Case No. CV  95-09509),  and
Crandon Capital Partners v. Kraemer,  et al.,  respectively  (collectively,  the
"Arizona  Actions").  Subsequently,  the Arizona Actions were consolidated.  The
Arizona Actions seek, among other things,  unspecified money damages and contain
allegations which include violations of Arizona securities law, fraud, negligent
misrepresentation,  breach of fiduciary duty,  negligence and gross  negligence.
The Company is not a named defendant in these lawsuits.  Further,  the Company's
Reorganization  Plan  provided  for the  discharge  of claims  asserted in class
action lawsuits against the Company.  However,  the Company could be required to
indemnify  certain of the  Director/Officer  Defendants if such defendants incur
expenses or  liability  in the  Arizona  Actions  and seek  indemnification.  In
connection with the settlement described below, the Director/Officer  Defendants
agreed  to  limit  their   aggregate  claim  for   indemnification   in  certain
circumstances.

         An  agreement  (the  "Settlement  Agreement")  was  previously  reached
pursuant to which the plaintiffs and the  Director/Officer  Defendants agreed to
settle and compromise  the Arizona  Actions in their  entirety,  as such actions
relate to the  Director/Officer  Defendants  and the Company,  in exchange  for,
among  other  things,  $12.75  million.  Of such  amount,  $1.5  million,  which
represents the self-insured  retention under the Company's applicable directors'
and officers' insurance policies, has been paid by the Company. In addition, the
Company  paid  $250,000  on  behalf of DMB.  Certain  issuers  of the  Company's
directors'  and  officers'  insurance  policies,  together  with  the  Company's
insurance  carriers,  have  agreed to fund the  balance of the  settlement.  The
Company  does not  believe  that its  remaining  obligations  to  directors  and
officers  will exceed its  insurance  coverage.  The  Settlement  Agreement  and
amendments thereto were approved by the Court at a final settlement hearing held
on February 14, 1997. The Court's  decision is being appealed by Arthur Andersen
LLP.

     The Company is also involved in various legal  proceedings  which generally
represent  ordinary routine litigation  incident to its business,  some of which
are covered in whole or in part by insurance.  In the Company's opinion, none of
the pending  litigation  matters  will have a material  adverse  effect upon the
Company's financial position, results of operations or cash flow.

         1.10 Independent Activities.

                  1.10.1  The  General  Scope  of  Independent  Activities.  The
Members hereby  expressly agree and acknowledge that each of the Members (either
directly, or through its Affiliates, officers, directors, members, shareholders,
agents and  employees)  is involved in  transactions,  investments  and business
ventures and undertakings of every nature,  which include,  without  limitation,
activities  which are not  associated  in any manner with real estate as well as
the ownership, construction,  development, marketing, sale and operation of real
property and improvements of every type and nature thereon (all such investments
and activities being referred to hereinafter as the "Independent Activities").

                  1.10.2 Specific Independent  Activities.  Without limiting the
generality of Section 1.10.1,  the Members  acknowledge that (a) the Independent
Activities  of SunPower  or its  Affiliates  include,  without  limitation,  the
ownership and development of real property  adjacent to the Property that may be
deemed to be in  competition  with the Property for utility and other  services,
purchasers and other matters; and (b) the Independent Activities of UDC include,
without  limitation,  the ownership and  development of residential  real estate
projects throughout Maricopa County, Arizona.

                  1.10.3   Waiver  of  Rights   with   Respect  to   Independent
Activities.  Nothing in this  Agreement  shall be construed to: (a) prohibit any
Member  or its  Affiliates  from  continuing,  acquiring,  owning  or  otherwise
participating  in any Independent  Activity that is not owned or operated by the
Company,  even if such Independent Activity is or may be in competition with the
Company;  and (b) require any Member to allow the Company or the other Member to
participate in the ownership or profits of any such Independent Activity. To the
extent any Member would have any rights or claims  against the other Member as a
result of the Independent  Activities of such Member or its Affiliates,  whether
arising by  statute,  common law or in equity,  the same are hereby  waived with
respect to the operation of the Company and the development and operation of the
Project.

                  1.10.4 Limitation on Company Opportunities. Each Member hereby
represents and warrants to the other Member that it has not been offered,  as an
inducement to enter into this Agreement, the opportunity to participate with the
other Member in the ownership or profits of any Independent Activity of any kind
whatsoever of such Member or its Affiliates.  The Members expressly  acknowledge
that  the  opportunities  of the  Company  shall  be  limited  to the  Permitted
Activities  with respect to the  Property and shall not extend to any  property,
investment or activity other than the Permitted  Activities  conducted solely on
or with respect to the Property.

         SECTION 2. MEMBERS; PERCENTAGE INTERESTS; CAPITAL CONTRIBUTIONS; LOANS

         2.1  Members.  The name and address of each Member are set forth on the
signature pages to this Agreement.

         2.2 Percentage Interests.  The Members' initial Percentage Interests in
the Company are as follows:

         SunPower:            50%
         UDC:                 50%

The Members'  initial  Percentage  Interests  shall be subject to  adjustment as
provided in Section 2.9 hereof.

         2.3 Initial Capital Contribution by SunPower.

                  2.3.1 Contribution of Property.  SunPower shall contribute the
Property  to  the  Company  on  the  terms  and  conditions  set  forth  in  the
Contribution  Agreement.  All  warranties  by  SunPower  under the  Contribution
Agreement  shall inure to the benefit of the Company as if set forth  separately
herein. In connection with the contribution of the Property to the Company,  the
parties  shall  execute  and  deliver  all  documents   contemplated  under  the
Contribution Agreement.

                  2.3.2 Seller Note and Deed of Trust.  The Members  acknowledge
that:

                              2.3.2.1 the  Property is  encumbered  by a deed of
trust (the  "Seller  Deed of Trust") in favor of Power  Enterprises,  an Arizona
general partnership (the "Seller"), securing payment of a promissory note in the
initial  principal  amount of  $3,971,545.60  (the  "Company  Note to  Seller"),
resulting from the division of a $5,927,680 promissory note given by SunPower to
Seller in connection with  SunPower's  purchase of the Property into the Company
Note to Seller and a second promissory note (the "SunPower Note to Seller"), all
in accordance with the Note Division  Agreement to be entered into among Seller,
SunPower and the Company in connection with the execution of this Agreement (the
"Note Division Agreement"); and

                              2.3.2.2  the  Company  Note  to  Seller  is  cross
collateralized and cross defaulted with the SunPower Note to Seller.

The Company will perform all  obligations  and make all payments with respect to
the Company Note to Seller and SunPower  will perform all  obligations  and make
all payments with respect to the SunPower Note to Seller.

                  2.3.3  Agreed  Net  Value of  Contribution.  In  exchange  for
contributing the Property to the Company,  SunPower shall be deemed to have made
a Capital  Contribution  to the Company in an amount (the  "Agreed Net  Property
Value") equal to the excess of:
                                       4
<PAGE>
                              2.3.3.1 $14,000  multiplied by the number of gross
acres included in the Property (the "Gross Property Value"), over

                              2.3.3.2 an amount equal to the outstanding balance
of principal and interest, if any, under the Company Note to Seller,  determined
as of the date the Property is contributed to the Company.

Immediately  following its  contribution  of the Property,  SunPower  shall have
Unreturned  Capital  Contributions in an amount equal to the Agreed Net Property
Value.

         2.4 Initial Capital  Contribution by UDC.  Concurrently with SunPower's
contribution of the Property to the Company,  and through the escrow established
in connection with such contribution,  UDC shall contribute  $818,945 in cash to
the  Company,  which  shall  be used to pay  closing  costs  under  the  escrow,
reimburse  SunPower for $818,945 of expenses  incurred by it in contemplation of
the formation of the Company.  The expenses to be reimbursed to SunPower are set
forth on an itemized list that has been provided to and approved by UDC prior to
the execution of this Agreement.

         2.5 Additional Capital  Contributions.  The Members shall contribute to
the Company from time to time such amounts as are reasonably required to pay the
Approved  Expenses of the Company,  as and when the same come due; provided that
neither  Member  shall be  obligated to make  additional  Capital  Contributions
pursuant to this Section 2.5 after such time as that Members'  aggregate Capital
Contributions to the Company pursuant to Sections 2.3, 2.4 and this Section 2.5,
as applicable,  are equal to the Gross Property Value. All Capital Contributions
pursuant to this Section 2.5 shall be made first by UDC,  until such time as the
Members' Unreturned Capital  Contributions are equal.  Thereafter,  all required
Capital  Contributions  shall  be made by the  Members  in  proportion  to their
respective  Percentage Interests in the Company,  determined at the time of each
such Capital Contribution.  All Capital  Contributions  pursuant to this Section
2.5 shall be due and  payable  not later  than ten  business  days  following  a
request  therefor by either  Member.  All  requests  for  Capital  Contributions
pursuant to this Section 2.5 shall be in writing and shall specify in reasonable
detail the Approved Expenses to be funded with such Capital Contributions.

         2.6 Failure to Make Payments Under Seller Notes and Deed of Trust.  The
Company  and  SunPower  shall  take all steps  that are  necessary  to cause one
another to be listed as parties  entitled  to  receive  notices of default  with
respect to the  Company  Note to  Seller,  the  SunPower  Note to Seller and any
instrument evidencing or securing the foregoing notes (collectively, the "Seller
Loan  Documents")  and to be  granted  the right to cure any  default  under the
Seller Loan Documents.  If the Company makes any payment or incurs any cost with
respect to a default by SunPower under any Seller Loan Document  relating to the
SunPower Note to Seller,  SunPower  shall  reimburse the Company upon demand for
any payment or cost thus incurred,  together with interest on the amount thereof
at the rate of 20% per annum. Additionally,  SunPower may not transfer or convey
to any entity all or any part of the real  property  that is subject to the deed
of trust securing the SunPower Note to Seller without the prior written  consent
of UDC (which UDC may  withhold  in its sole  discretion),  unless and until the
real property that is subject to the deed of trust  securing the Company Note to
Seller is no longer  security for the  SunPower  Note to Seller  (e.g.,  through
elimination of the  cross-collateralization or satisfaction of the SunPower Note
to Seller).  If 
                                       5
<PAGE>
SunPower  makes any payment or incurs any cost with  respect to a default by the
Company under any Seller Loan  Document  relating to the Company Note to Seller,
the Company  shall  reimburse  SunPower upon demand for any payment or cost thus
incurred,  together with  interest on the amount  thereof at the rate of 20% per
annum.  The Company shall be entitled to offset  against any amounts  payable or
distributable  to SunPower  under this  Agreement  the entire amount owed at any
time by  SunPower  to the  Company  pursuant  to  this  Section  2.6  (it  being
understood  that the foregoing  offset right shall be effective  against amounts
payable or distributable to SunPower regardless of any transfer or conveyance by
SunPower  of the  property  that is  subject to the deed of trust  securing  the
SunPower  Note to Seller  and  regardless  of any  consent to such  transfer  or
conveyance  by UDC).  If the  Company  owes any amount to  SunPower  at any time
pursuant to this Section  2.6,  the entire  amount owed shall be paid before the
Company makes any  distributions or payments to any Member or any Affiliate of a
Member pursuant to any provision of this Agreement. In addition to the foregoing
reimbursements:  (a)  SunPower  shall  indemnify,  defend and hold  harmless the
Company from and against any liability,  damage,  cost, expense,  loss, claim or
judgment  incurred  by the  Company  as a result  of  SunPower's  breach  of any
obligation  under any Seller Loan  Documents  relating to the  SunPower  Note to
Seller,  and (b) the Company shall indemnify,  defend and hold harmless SunPower
from and against any liability,  damage, cost, expense,  loss, claim or judgment
incurred by SunPower as a result of the Company's breach of any obligation under
any Seller Loan Documents relating to the Company Note to Seller.

         2.7 Intent to Finance  Approved  Expenses.  If,  during the term of the
Company,  funds  available  to the  Company  are  insufficient  to pay  Approved
Expenses when due, the Executive  Committee shall use its best efforts to obtain
a loan from a third party lender on commercially  reasonable terms acceptable to
the Executive Committee to fund such  insufficiency.  If the Executive Committee
is unable to secure  third-party  financing  to pay  Approved  Expenses on terms
acceptable to the Executive Committee,  then upon the written election of either
Member  delivered to the Executive  Committee,  the Members shall be entitled to
make Member Loans on the terms and  conditions set forth in Section 2.10 hereof;
provided  that in no event shall the  aggregate  Member Loans under Section 2.10
exceed $2,000,000 without the prior written consent of both Members.

         2.8 Limitations Pertaining to Capital Contributions.

                  2.8.1 Return of Capital.  Except as otherwise provided in this
Agreement,  no Member shall withdraw any Capital  Contributions  or any money or
other property from the Company without the written consent of the other Member.
Under circumstances  requiring a return of any Capital Contributions,  no Member
shall have the right to receive  property  other  than  cash,  unless  otherwise
specifically agreed in writing by the Members at the time of such distribution.

                  2.8.2 No  Interest  or Salary.  No Member  shall  receive  any
interest,  salary or drawing  with respect to its Capital  Contributions  or its
Capital  Account or for services  rendered on behalf of the Company or otherwise
in its  capacity as a Member,  except as  otherwise  expressly  provided in this
Agreement.

                  2.8.3 Liability of Members.  Except as agreed upon in writings
signed by the  Members,  no Member  shall be liable for the debts,  liabilities,
contracts or any other obligations of 
                                       6
<PAGE>
the  Company.  Except as agreed  upon by the  Members,  and except as  otherwise
provided by Section 29-651 of the Act or by any other  applicable state law, the
Members shall be liable only to make their Capital  Contributions  to the extent
provided in Sections  2.3, 2.4 and 2.5 hereof and no Member shall be required to
make any other Capital  Contributions or to loan any amounts to the Company.  No
Member  shall have any  personal  liability  for the  repayment  of the  Capital
Contributions or loans of the other Member.

                  2.8.4  No  Third  Party  Rights.  Nothing  contained  in  this
Agreement  is intended or will be deemed to benefit any creditor of the Company,
and no  creditor  of the  Company  will be  entitled  to require  the  Executive
Committee or any Member to solicit or demand additional Capital Contributions or
Member Loans.

                  2.8.5  Withdrawal.  Except as provided in Section 8 hereof, no
Member may voluntarily or  involuntarily  withdraw from the Company or terminate
its interest therein without the prior written consent of the other Member.  Any
Member who withdraws from the Company in breach of this Section 2.8.5:

                              2.8.5.1  shall  be  treated  as an  assignee  of a
Member's interest, as provided in the Act;

                              2.8.5.2 shall have no right to  participate in the
business  and affairs of the Company or to exercise any rights of a Member under
this Agreement or the Act; and

                              2.8.5.3  shall,  subject  to Section  8.5  hereof,
continue to share in  distributions  from the  Company,  on the same basis as if
such  Member had not  withdrawn,  provided  that any damages to the Company as a
result of such  withdrawal  shall be offset against amounts that would otherwise
be distributed to such Member. The right to share in distributions granted under
this Section 2.8.5 shall be in lieu of any right the  withdrawn  Member may have
under the Act to  receive a  distribution  or  payment  of the fair value of the
Member's interest in the Company.

         2.9 Failure to Make Additional Capital Contributions.

                  2.9.1 Notice.  If either Member (a  "Noncontributing  Member")
fails to make an additional Capital Contribution when required under Section 2.5
hereof when due,  and if the other Member (the  "Contributing  Member") has made
its corresponding Capital Contribution (the "Corresponding Contribution"),  then
the  Contributing   Member  may  give  written  notice  (the  "Notice")  to  the
Noncontributing Member setting forth the amount required to cure such delinquent
contribution   (the  "Capital   Amount").   From  and  after  the  Notice,   the
Noncontributing  Member shall have no right to issue an Offering Notice pursuant
to Section  5.13.1 or an Offer to Sell or Purchase  pursuant to Section  5.14.2.
The rights and powers suspended under the immediately  preceding  sentence shall
be  reinstated  only upon the  Noncontributing  Member's  funding of the Capital
Amount.

                  2.9.2  Remedies.  If  the  Noncontributing   Member  fails  to
contribute  the  Capital  Amount to the  Company  within 15 days  following  the
Notice,  then the  Contributing  Member may elect to withdraw the  Corresponding
Contribution  from the Company or to fund all or part of the 
                                       7
<PAGE>
Capital  Amount.  If the  Contributing  Member  funds the  Capital  Amount,  the
Members'  Unreturned  Capital   Contributions  and  Percentage  Interests  shall
immediately be adjusted to be as follows:

                              2.9.2.1 The  Noncontributing  Member's  Unreturned
Capital Contributions shall be reduced by an amount equal to 120% of the Capital
Amount  funded  by  the  Contributing  Member  and  the  Contributing   Member's
Unreturned Capital Contributions shall be increased by a like amount; and

                              2.9.2.2 Each Member's  Percentage  Interest in the
Company  shall be adjusted to equal the  quotient,  expressed  as a  percentage,
determined  by  dividing  (a) the  Member's  Unreturned  Capital  Contributions,
determined after the adjustment required under Section 2.9.2.1 hereof by (b) the
Members' aggregate  Unreturned Capital  Contributions to the Company at the time
of such adjustment.

         2.10 Member Loans.

                  2.10.1  Conditions to Member Loans. The Members may make loans
("Member  Loans") to the Company to pay  Approved  Expenses and to pay any other
material  cost or expense  within an Approved  Budget or  consistent in terms of
quality and amount with material costs and expenses contemplated by the Approved
Master Plan or an Approved Development Plan under the following conditions:  (a)
upon the written approval of the Executive Committee at any time during the term
of this Agreement;  or (b) subject to the provisions of Section 2.10.3, upon the
written  election  of any  Member,  delivered  to  the  Executive  Committee  in
accordance  with  Section  2.7  hereof,  up to the full  amount of Member  Loans
authorized under Section 2.7 hereof.

                  2.10.2  Terms for  Repayment.  Unless  otherwise  approved  in
writing by the Executive Committee at the time of a Member Loan:

                              2.10.2.1   each  Member  Loan  shall  bear  simple
(noncompounded) interest at the Prime Rate plus 1% per annum;

                              2.10.2.2  each Member Loan shall be repaid  solely
from the  Company's  Net Cash Flow,  prior to any  distributions  to the Members
pursuant to Section 3 or 9.2.3.2 hereof; and

                              2.10.2.3  all  payments  on Member  Loans shall be
applied first to repay interest on all Member Loans, in proportion to the unpaid
interest  outstanding on all such Member Loans,  and then to repay  principal on
all Member Loans, in proportion to the unpaid principal  outstanding on all such
Member Loans.

                  2.10.3 Members' Right to  Participate.  Prior to accepting any
Member Loans,  the Executive  Committee  shall  provide  written  notice to each
Member of the total amount of the currently  proposed  Member Loan.  Each Member
shall have the right to fund a pro rata share of each Member Loan, based on that
Member's  Percentage  Interest in the  Company,  by  tendering  its share of the
Member Loan to the Company  within 15 days  following the Executive  Committee's
notice under this Section 2.10.3.
                                       8
<PAGE>
                  2.10.4  Optional  Nature of Member  Loans.  No Member shall be
required to make a Member Loan, unless that Member has agreed in writing to make
such Member Loan,  and no Member shall have any  obligation  to repay the Member
Loans of the other  Member or to make  Capital  Contributions  to the Company to
provide it with funds with which to repay Member Loans.

         SECTION 3.  DISTRIBUTIONS

         3.1 Distributions.  Except as provided in Section 9 hereof, and subject
to the provisions of Section 2.10 hereof,  Net Cash Flow shall be distributed to
the Members on a quarterly basis in the following order of priority:

                  3.1.1  First,  to the Members in a manner  which  brings their
respective   Unreturned   Capital   Contributions  into  proportion  with  their
Percentage  Interests (at the time of such distribution) as quickly as possible;
and

                  3.1.2 Second, to the Members in proportion to their Percentage
Interests at the time of each such distribution.

         SECTION 4.  TAX ALLOCATIONS

         4.1 General Allocation Rules.

                  4.1.1 General  Allocation  Rule.  For each taxable year of the
Company,  after the  application  of Section 4.2 hereof,  Profits  and/or Losses
shall be  allocated  to the  Members  in a manner  which  causes  each  Member's
Adjusted  Capital  Account Balance to equal the amount that would be distributed
to  such  Member   pursuant  to  Section  9.2.3.2  hereof  upon  a  hypothetical
liquidation of the Company in accordance with Section 4.1.2 below.

                  4.1.2  Hypothetical  Liquidation  Defined.  In determining the
amounts  distributable  to the Members under Section 9.2.3.2 upon a hypothetical
liquidation,  it shall be presumed that (a) all of the Company's assets are sold
at their  respective  values  reflected  on the books of account of the Company,
determined in accordance  with Code Section  704(b) and  Regulations  thereunder
("Book  Value"),  without  further  adjustment,  (b) payments to any holder of a
nonrecourse debt are limited to the Book Value of the assets securing  repayment
of such debt,  and (c) the  proceeds of such  hypothetical  sale are applied and
distributed in accordance with Section 9.2 hereof.

                  4.1.3 Special Loss Allocation. If the Company incurs Losses at
any time when the Members'  Adjusted  Capital Account Balances have been reduced
to or below zero, such Losses shall be allocated to the Members in proportion to
their Percentage Interests.

                  4.1.4  Special  Profits  Allocation.  If  the  Company  incurs
Profits at any time when the Members' Adjusted Capital Account Balances are less
than zero and the hypothetical  liquidation described in Section 4.1.2 would not
result in any  distributions  to the Members,  Profits 
                                       9
<PAGE>
shall be  allocated  to the Members in  proportion  to their  negative  Adjusted
Capital Account Balances, until such negative balances have been eliminated.

                  4.1.5 Item Allocations. To the extent the Executive Committee,
upon consultation with the Company's accountants, determines that allocations of
Profits and/or Losses over the term of the Company are not likely to produce the
Adjusted Capital Account Balances  intended under this Section 4.1, then special
allocations  of income,  gain,  loss  and/or  deduction  shall be made as deemed
necessary by the Executive  Committee to achieve the intended  Adjusted  Capital
Account Balances.

         4.2 Regulatory and Curative  Allocations.  The allocations set forth in
Section 4.1 are intended to comply with the requirements of Regulations Sections
1.704-1(b)  and  1.704-2.  If the Company  incurs  "nonrecourse  deductions"  or
"partner  nonrecourse  deductions,"  or if there is any change in the  Company's
"minimum  gain" or "partner  nonrecourse  debt minimum gain," as defined in such
Regulations,  or if  the  Executive  Committee  determines  that  the  foregoing
allocations fail for any reason to comply with the  Regulations,  the allocation
of  Profits,  Losses and items  thereof to the  Members  shall be  modified in a
reasonable  manner deemed  necessary or advisable by the Executive  Committee to
comply  with the  Regulations;  provided  that to the  extent  permitted  by the
Regulations,  all "nonrecourse  deductions" shall be allocated to the Members in
proportion to their Percentage Interests. In accordance with Code Section 704(c)
and the Regulations thereunder, income or gain resulting from the disposition of
all or any portion of the Property shall be specially allocated to SunPower,  to
take into  account  the excess of the Gross  Property  Value over the  Company's
initial tax basis in the  Property  (the  "Built-in-Gain").  For purposes of the
immediately  preceding  sentence,  the  Built-in-Gain  shall be  allocated  on a
proportional  basis across the entire  Property,  in the same ratio in which the
Company's  initial  tax  basis is  allocated  across  the  Property.  As soon as
practicable following the execution of this Agreement,  SunPower shall provide a
written  statement to the Company  setting forth the Company's  initial basis in
the Property.

         4.3 Capital  Account.  A Capital  Account shall be maintained  for each
Member in accordance with the Regulations, under uniform policies and procedures
established by the Executive Committee.

         SECTION 5.  MANAGEMENT

         5.1 Management of Company.

                  5.1.1 General. Except as specifically provided in Section 5.8,
the right to manage, control and conduct the business and affairs of the Company
shall be vested solely in the Executive Committee.

                              5.1.1.1  Executive  Committee.  The Members  shall
establish a committee (the "Executive  Committee"),  which shall consist of four
representatives   (individually,   a   "Representative"   and  collectively  the
"Representatives")  to act on behalf of the Members on all  matters  relating to
the Company.  SunPower  shall  designate two  Representatives  (with its initial
Representatives  being  John W.  Graham  and  James C.  Hoselton)  and UDC shall
designate two  Representatives  (with its initial  Representatives  being Robert
McLaughlin and Darrell  Bolognesi).  
                                       10
<PAGE>
Representatives  may be  changed  upon  written  notice  from the  Member  which
appointed the Representative who is being changed to the other Member,  provided
that all successor Representatives of a Member shall be reasonably acceptable to
the other  Member.  Each of SunPower and UDC may appoint one or more  alternates
for  the  Representative(s)   appointed  by  it,  which  alternate(s)  shall  be
reasonably  acceptable  to the other Member and shall have all the powers of the
initially  designated  Representative(s)  in his (their) absence or inability to
serve.

                              5.1.1.2  Meetings.  A  meeting  of  the  Executive
Committee may be called by any Member or its Representatives upon written notice
delivered not less than five business days before the meeting, setting forth the
time and general purpose of the meeting. Unless the Representatives collectively
agree otherwise  (which agreement may include an arrangement to hold meetings by
telephone conference), all meetings shall be held in the offices of the Company.
Representatives may bring to any meeting such employees,  agents,  professionals
and  advisors  as they deem  necessary  or  appropriate  to assist  them at such
meeting.

                              5.1.1.3 Decisions.  All decisions of the Executive
Committee shall require unanimous agreement of the Representatives, which may be
stated in person or given by proxy or pursuant to written  agreements  signed by
the  Representatives  (with  or  without  holding  a  meeting).  Subject  to the
provisions  of Section 5.8, any Dispute (as defined in Section 5.6) with respect
to  decisions  by the  Executive  Committee  shall be subject to  resolution  in
accordance with Section 5.7.

                              5.1.1.4 Required Effort. The Representatives shall
devote such time to the Company and its  business as is  appropriate  to conduct
the business of the Executive Committee in an effective manner, but shall not be
required to devote  their full time  efforts to the  Executive  Committee or the
Company.

                              5.1.1.5 Indemnity; Insurance. The liability of the
Representatives  shall be limited, and the Representatives  shall be indemnified
for their acts to the extent provided in Section 5.10 hereof.  Either Member may
procure (at its sole expense)  errors and omissions  insurance  coverage for its
Representatives,  for policy  limits  and risks  reasonably  acceptable  to such
Member.

                  5.1.2  Assignment  and  Delegation  of Duties.  The  Executive
Committee shall apportion responsibility for the management and operation of the
Company   between   the   Members  on  a   reasonable   basis,   such  that  the
responsibilities and duties allocated to the Members are commensurate with their
respective ownership interests in the Company. The responsibilities allocated to
each Member shall include specific duties,  privileges,  powers and authority as
deemed  necessary  by the  Executive  Committee  to  further  the  business  and
operations of the Company.

                  5.1.3 Duties and Authority of Members.

                              5.1.3.1  Right  and  Duty  to  Complete  Allocated
Responsibilities.  Subject to the terms of the Approved  Master Plans,  Approved
Development Plans and Approved Budgets,  and to any additional  limitations that
may be imposed from time to time by the Executive  Committee,  each Member shall
have the  right  and the  duty to  exert  reasonable  efforts  in a  prompt  and
businesslike  manner to do,  accomplish  and complete,  in accordance  with this
Agreement,  all  responsibilities  and duties  allocated to it by the  Executive
Committee.

                              5.1.3.2 Standard of Performance. Each Member shall
exercise such skill and care in fulfilling its  responsibilities and duties as a
prudent developer with experience in developing  projects like the Project would
exercise in dealing with its own property.

                              5.1.3.3 Effort. The Members shall devote such time
to the Company as is  appropriate  to  supervise  and  complete in an  effective
manner the tasks and  activities  assigned to them, but shall not be required to
devote their full time efforts to the Company.

                              5.1.3.4  Means  of  Performance.  Each  Member  is
hereby authorized to take all actions reasonably deemed necessary by it to carry
out its rights and duties under this Agreement.  Subject to the Approved Budget,
and to any additional  limitations  that may be imposed from time to time by the
Executive  Committee,  each  Member may engage  independent  contractors  at the
expense of the Company to assist such Member in performing its duties under this
Agreement  and to  render  services  to  the  Company  in  connection  with  the
development, operation and marketing of the Project.

                  5.1.4 Signature Power of Members.  Either Member, acting alone
and without the joinder of the other Member, shall have the power to execute and
deliver  documents  and  instruments  of every  type and nature on behalf of the
Company,  which shall be binding on the  Company;  provided,  however,  that the
signature  of both  Members  shall be required for  documents  evidencing  Major
Decisions.  Any  Person  dealing  with the  Company  may rely,  without  further
inquiry,  on a  certificate  signed  by  any  Member  as  to  the  existence  or
nonexistence of any fact or facts which constitute a condition precedent to acts
by the Member or which are in any other  manner  germane  to the  affairs of the
Company.  The  Members'  respective  Representatives  shall be their  designated
agents to execute documents on behalf of each such Member and, in addition, each
Member may provide to the other Member from time to time  written  notice of any
other agents designated by the Member to execute documents on its behalf.

                  5.1.5 Operation of Golf Course.  The Members  acknowledge that
it is there intent to operate the golf course to be  constructed  on the Project
for so long as the  Company's  ownership  of the  golf  course  (as  opposed  to
ownership by unrelated  third parties) is  advantageous  to the  development and
disposition  of the  remainder of the Project or to the overall  financial  well
being of the Company. The Members do not intend for the Company to hold the golf
course as a permanent investment or permanent business operation.

         5.2 Master Plan.

development of the Property (such  development  being referred to hereinafter as
the  "Project")  shall be based on an overall  plan for  development  (a "Master
Plan")  approved  from time to time by the  Members or the  Executive  Committee
pursuant to this Section 5.2. Any such plan,  including  modifications  thereto,
that is approved by the Members of the Executive  Committee  shall be termed the
"Approved  Master Plan." The initial  Approved Master Plan is attached hereto as
Exhibit  A.  Any  Representative  may  from  time to time  submit  revisions  or
modifications  to the  Approved  Master  Plan then in  effect  to the  Executive
Committee  for its review and  approval in  accordance  with Section 5.6 hereof;
provided that no revisions or modifications shall be implemented unless approved
in accordance with Section 5.6 hereof.

                  5.2.2 Delegation of Responsibilities  with Respect to Approved
Master Plan.  To the extent all  necessary  governmental  approvals  and actions
reasonably required to vest the Company's development rights with respect to the
Project have not been  completed  prior to the  formation  of the  Company,  the
Executive  Committee  shall delegate to the Members,  in accordance with Section
5.1.2, the responsibility  for obtaining such governmental  approvals and taking
such  actions  (including,   without  limitation,  the  duty  to  supervise  the
activities of all engineers,  land planners and other  professionals that may be
required to obtain the foregoing governmental approvals and vested rights).

                  5.2.3  Contents  of Master  Plan.  The  Master  Plan  shall be
prepared in accordance  with good land planning  principles  and shall  include,
without limitation:

buildings, retail space, etc.) to be constructed on the Property, whether by the
Company or by purchasers from the Company, and a summary, by major land area, of
the anticipated density of development; and

                              5.2.3.3 a description of each phase of development
of the Project,  identifying the proposed  sequence of development,  and setting
forth for each phase a tentative  schedule (based on events or time or both) and

                  5.3.1   Submission   and  Approval.   Prior  to  any  material
expenditure of funds for any building phase of the Project,  the Representatives
shall prepare a plan (a "Development Plan") detailing the scope of the Company's
operations  and  planned  development  of  that  phase  (including  those  items
described in Section 5.2 hereof) and submit it to the  Executive  Committee  for
review and approval in  accordance  with Section 5.6 hereof.  Development  Plans
shall  be  prepared  from  time  to  time  as  market  conditions   permit.  Any
Representative  may from  time to time  submit  revisions  or  modifications  to
Development  Plans to the  Executive  Committee for approval in the same manner;
provided that no revisions or modifications shall be implemented unless approved
in accordance  with Section 5.6 hereof.  Each  Development  Plan,  including any
revisions thereto, which is approved in accordance with Section 5.6 hereof shall
be termed an "Approved Development Plan."

                  5.3.2 Delegation of Responsibilities  with Respect to Approved
Development  Plans.  Once an Approved  Development Plan has been adopted for any
phase of the Project,  the  Representatives  shall  delegate to the Members,  in
accordance with Section 5.1.2, the responsibility for implementing such Approved
Development Plan. The Members acknowledge that a separate Development Plan shall
be  required  in  connection  with  each  phase of the  Project  and  that  each
Development  Plan shall be  consistent  with the  Approved  Master  Plan then in
effect.

                  5.3.3  Marketing  Agreement.  The Company  shall enter into an
agreement with UDC at Power Ranch Marketing L.L.C. to provide marketing services
with respect to the Project.

         5.4 Contents of Development  Plans.  Unless  otherwise  approved by the
Executive Committee in accordance with Section 5.6 hereof, each Development Plan
shall detail the overall plan for design, development, construction, completion,
financing,  operation  and sale of the  relevant  phase or aspect of the Project
covered by the Development Plan, and shall include, but not be limited to:

                  5.4.1 a proposed plat and preliminary site plans for the phase
of  the  Project  to  be  developed  which  are  designed  to  comply  with  the
requirements of all governmental authorities with jurisdiction over the Project;

                  5.4.2 a general  description of the type of improvements to be
constructed as part of that phase of the Project and any  covenants,  conditions
and restrictions proposed by the Company to be applied to that phase;

         5.5 Approval of Budgets.

                  5.5.1  Types  of  Budgets.   From  time  to  time  during  the
development of the Project,  the  Representatives  shall prepare and present for
the  approval of the  Executive  Committee  in  accordance  with Section 5.6 the
following  budgets (each, a "Budget"):  (a) a separate,  general budget for each
phase of the Project covered by an Approved  Development Plan,  setting forth in
general terms the budget needs for such phase over its  anticipated  development
term,  (b) a separate  annual budget for each phase of the Project  currently in
operation or development under an Approved  Development  Plan,  setting forth in
specific  terms and specific  detail all costs expected to be incurred under the
relevant  Approved  Development Plan, and (c) a separate annual operating budget
for the Company,  setting forth in detail all anticipated Company expenses which
are not addressed in other more specific budgets.  Any  Representative  may from
time to time  submit  revisions  or  modifications  to Budgets to the  Executive
Committee for approval;  provided  that no revisions or  modifications  shall be
implemented unless approved in accordance with Section 5.6 hereof.

                  5.5.2  Annual  Operating  Budgets.  Not  later  than  90  days
following  the  execution  of this  Agreement,  the  Executive  Committee  shall
approve,  in accordance  with the  provisions of Section 5.6, an initial  annual
operating  budget for the 1998 calendar year (the "Initial  
                                       15
<PAGE>
Operating Budget"). The Representatives shall present a revised annual operating
budget for approval by the Executive Committee not later than November 1 of each
year  preceding  the year  covered by the  proposed  budget,  and the  Executive
Committee shall approve the annual  operating  budget by December 1 of each year
in accordance with the provisions of Section 5.6.

                  5.5.3  Limitation on  Expenditures;  Use of Reserves.  Budgets
shall  include  a  reasonable   contingency   reserve  for  unanticipated  costs
associated with the matters covered  thereby.  Specific  expenditures to develop
and  operate  the  Project  may be made only  pursuant  to an  Approved  Budget;
provided that the Members  shall have  discretion  to use  contingency  reserves
included in any Approved Budget in any reasonable  manner and shall be permitted
to make  reasonable  adjustments  between  line items  reflected  on an Approved
Budget if the expenses  intended to be paid pursuant to the line item from which
funds are  transferred  are in fact incurred and paid (at a total cost less than
budgeted)  and the  items on which  the  transferred  funds  are  expended  were
included among the items set forth in the Approved  Budget (and were incurred at
a cost greater than budgeted).  Notwithstanding  the foregoing,  any increase in
excess of 25% in any  individual  line item in an Approved  Budget that  exceeds
$25,000 shall require the approval of the Executive Committee.

                  5.5.4 Definitions  Relating to Budgets.  The Initial Operating
Budget and each other Budget, including any revisions thereto, which is approved
in accordance with Section 5.6 hereof, shall be termed an "Approved Budget." All
expense items  identified in the  Company's  Approved  Budgets from time to time
shall constitute "Approved Expenses" of the Company.

         5.6 Mechanism for Obtaining  Consents.  The Representatives may propose
approval of a Master Plan,  Development Plans, Budgets and amendments thereto by
the Executive Committee by giving notice thereof to each  Representative  (which
notice  may   include   alternative   recommendations   or   proposals   by  the
Representatives).  The  Representatives  shall  cooperate in good faith to reach
unanimous  agreement on all matters  submitted for the approval of the Executive
Committee (including,  without limitation,  the matters set forth in Section 5.8
hereof, any Budgets,  Master Plans,  Development Plans and modifications thereto
proposed  by  a   Representative   and  any  other   matters   proposed  by  the
Representatives)  within 30 days of their submission to the Executive Committee.
If agreement by a unanimous vote of the Representatives  cannot be achieved with
respect to a  particular  issue (the  absence of  agreement  on that issue being
referred to herein as a "Dispute")  within such 30-day period,  the parties wish
to provide for an efficient and prompt  resolution  thereof  through the dispute
resolution   mechanism   of  Section  5.7,   rather  than  through   litigation.
Accordingly,  the Members hereby waive their rights to institute litigation with
respect to any Dispute arising under this  Agreement,  and consent instead to be
bound by the  results  of the  dispute  resolution  mechanism  of  Section  5.7.
Notwithstanding  the foregoing,  disagreements with respect to matters described
in Section 5.8 shall not be "Disputes" nor be subject to resolution  pursuant to
Section 5.7,  provided that a disagreement  regarding whether any act is outside
the scope of the Company's  Permitted  Activities shall constitute a Dispute and
shall be subject to resolution pursuant to Section 5.7.

         5.7      Dispute Resolution.

<PAGE>
                  5.7.1 Initial  Designation of  Arbitrators.  The Company shall
maintain  a list of five or more  individuals  whom the  Members  have  mutually
agreed are qualified to serve as  arbitrators to resolve  Disputes.  The initial
arbitrator  list  shall be  agreed  upon by the  Members  and  attached  to this
Agreement not later than January 15,1998.

                  5.7.2  Disclosure of Business  Relationships;  Replacement  of
Arbitrator.  The Members  shall  disclose to each other in writing all  material
business  relationships they have had in the past five years with any arbitrator
before an arbitrator  is added to the  arbitrator  list.  The Members shall also
disclose  to each other in writing  all  material  business  relationships  they
develop with an arbitrator  once the arbitrator has been added to the arbitrator
list. An  individual  shall remain on the  arbitrator  list until removed by the
mutual  consent of the Members;  provided  that if any Person  designated on the
arbitrator  list  dies,  refuses  to serve or for any other  reason is unable to
serve,  the Members shall designate an additional  Person to fill the vacancy on
the arbitrator  list. An individual  shall be added to the arbitrator  list only
upon the  unanimous  consent of the Members;  provided  that if a vacancy on the
arbitrator  list is not  filled  within 30 days of the event  that  caused  such
vacancy,  the remaining  Persons on the arbitrator  list shall promptly choose a
new arbitrator to fill the vacancy.

                  5.7.3  Dispute  Notice.  If both  Representatives  of a Member
believe that a Dispute exists, the Member shall notify the other Member thereof,
which  notice (a  "Dispute  Notice")  shall  identify  the Dispute and set forth
briefly the notifying Member's position with respect to the Dispute. As promptly
as  practicable,  and in any event  within one week of the giving of the Dispute
Notice,  the  Members  shall meet in an attempt to resolve the  Dispute.  If the
Dispute  cannot be resolved at that  meeting,  either  Member may  institute the
arbitration process on the terms set forth in Section 5.7.4.

                  5.7.4 Arbitration.  The arbitration process shall be conducted
by an arbitrator  selected by random means from the  arbitrator  list  described
above.  In  general,  the  arbitrator  shall  follow  the rules of the  American
Arbitration Association, but shall have discretion to vary from those guidelines
in light of the  nature  or  circumstances  of any  particular  Dispute.  In all
events, unless waived by the Members, the arbitrator will conduct an arbitration
hearing at which the  Members  and their  counsel  shall be present and have the
opportunity to present evidence and examine the evidence  presented by the other
Member. The proceedings at the arbitration  hearing shall,  unless waived by the
Members,  be  conducted  under  oath  and  before  a court  reporter.  Upon  the
conclusion of the arbitration  hearing, the arbitrator shall and must select the
position  offered by one of the Members with respect to each individual  Dispute
(i.e.,  each issue presented for  resolution),  without  variation.  The parties
shall cooperate in good faith to permit a conclusion of the arbitration  hearing
within 90 days  following  the meeting  described  in Section  5.7.3,  and shall
endeavor to submit a joint statement  setting forth each Dispute to be resolved,
including a summary of each Member's  position on each Dispute.  The decision of
the  arbitrator  with  respect to any Dispute  shall be final and binding on the
Members and shall be treated as an approval of the matter subject to the Dispute
by the Members pursuant to Section 5.6.

                  5.7.5  Standards  of  Conduct.  The  Members  agree  that with
respect to all aspects of the dispute  resolution  process contained herein they
will  conduct  themselves  in a manner  
                                       17
<PAGE>
intended to assure the integrity and fairness of that process. To that end, if a
Dispute  is  submitted  to  arbitration,  the  Members  agree that they will not
contact or communicate with the arbitrator with respect to any Dispute either ex
parte or outside of the contacts and communications contemplated by this Section
5.7, and the Members further agree that they will cooperate in good faith in the
production of  documentary  and  testimonial  evidence in a prompt and efficient
manner to permit the review and evaluation thereof by the other Member.

                  5.7.6 Costs.  The cost of resolving any Dispute by arbitration

all purposes of this Agreement).

         5.8 Major Decisions. Notwithstanding any provision of this Agreement to
the contrary, the following matters (each, a "Major Decision") shall require the
consent  of both  Members,  which  may be  withheld  in the  sole  and  absolute
discretion of each Member (and which shall not be subject to resolution pursuant

         5.9 Special Considerations for Master Plan, Development Plans and Other
Matters.  The provisions of this Section 5.9 are intended to serve as guidelines
to the Executive  Committee in attempting to agree on the Approved  Master Plan,
the  Approved  Development  Plans,  and the Approved  Budgets and other  matters
contemplated  by this  Agreement  (and to  serve as a basis  or  standard  to be
applied by an arbitrator pursuant to Section 5.7 hereof, if necessary).

                  5.9.1 Agreement to Optimize  Returns.  It is the intent of the
Company  to  develop  the  Project  as soon as market  and  other  circumstances
reasonably  permit.  The Master Plan and each Development Plan shall be prepared
in a manner  which  optimizes  the  Members'  returns  from the Project over its
contemplated  development cycle,  consistent with good land planning principles,
prudent business practices and market conditions.

                  5.9.2 Effect on Residual Property. Each Development Plan shall
allow any portions of the Property that are not subject to Approved  Development
Plans  to be  developed  and  marketed  by the  Company  in an  orderly  manner,
independent  of any  portions  of the  Property  that are  subject  to  Approved
Development Plans.

                  5.9.3 Consideration of Parties' Varying Interests.  The Master
Plan, each Development Plan and each Budget shall take into consideration all of
the facts  relating to the  Members and the  Property,  including  the  Members'
respective  capital  investments  and  interests  in the  Company,  the economic
sharing arrangements contemplated by this Agreement and the need for development
and use of the Property in an orderly  manner that protects the interests of all
Members.

         5.10   Limitations   on   Liability;    Indemnity.   No   Member,   its
Representatives  or its or their  Affiliates (an "Actor") shall be liable to the
Company or the other  Members  for  actions  taken in good faith by the Actor in
connection  with the Company or its  business;  provided that the Actor shall in
all  instances  remain  liable  for acts in  breach of this  Agreement  or which
constitute bad faith,  fraud,  willful misconduct or gross negligence (except to
the  extent  the  Company  is  compensated  for the same by  insurance  coverage
maintained  in accordance  with this  Agreement).  The Company,  its receiver or
trustee shall  indemnify,  defend and hold harmless each Actor, to the extent of
the Company's assets (without any obligation of any Member to make contributions
to the Company to fulfill  such  indemnity),  from and  against  any  liability,
damage, cost, expense, loss, claim or judgment incurred by the Actor arising out
of any claim based upon acts  performed  or omitted to be performed by the Actor
in connection  with the business of the Company,  including  without  limitation
attorneys'  fees and costs incurred by the Actor in the settlement or defense of
such claim;  provided that no Actor shall be  indemnified  for claims based upon
acts  performed or omitted in breach of this  Agreement or which  constitute bad
faith, fraud, willful misconduct or gross negligence.

         5.11  Compensation  and Expenses of the Members.  The Members  shall be
entitled to reimbursement  from the Company for costs incurred by them and their
Representatives  in connection with the performance of their  respective  duties
hereunder  in the  manner  and  to the  extent  set  forth  on  Exhibit  C.  The
reimbursements  set forth on Exhibit C are  intended  to fully  compensate  each
Member for any direct  expenses  incurred by the Members or the  Representatives
                                       19
<PAGE>
for legal,  accounting,  auditing and other services provided for the benefit of
the Company  (whether  rendered by Affiliates of a Member or  Representative  or
otherwise) and for any facilities  (such as office space) and supplies  provided
to the  Company  and,  except  as set  forth on  Exhibit  C the  Members,  their
Affiliates and their Representatives shall not receive any reimbursement for the
foregoing  items  or  matters,   nor  shall  they  receive  any  fees  or  other
compensation from the Company,  unless  unanimously  agreed from time to time by
the Members.

         5.12 [Intentionally deleted].

         5.13  Disagreement  on Major  Decision.  This Section 5.13 sets forth a
procedure pursuant to which either Member may cause a sale of the Project on the
terms and subject to the conditions set forth herein.

                  5.13.1  Offering  Notice.  If a Member gives written notice to
the other  Member that it believes an  irreconcilable  disagreement  exists with
respect to a Major Decision,  and if such disagreement is not resolved within 10
days  following  delivery  of such  notice,  then at any time after such  10-day
period and until such disagreement is resolved by the Members, either Member (an
"Initiating  Member") may provide written notice (the "Offering  Notice") to the
other Member (the "Responding  Member")  setting forth in reasonable  detail the
terms and  conditions  upon  which the  Initiating  Member  desires  to sell the
Project. The date on which the Responding Member receives the Offering Notice is
referred to hereinafter  as the "Option Notice Date." The Offering  Notice shall
include the following:

                              5.13.1.1 a stated  purchase  price (which is fixed
in amount and not subject to adjustment for any  contingencies  or other events)
for the Project (the "Offered Price");

                              5.13.1.2  the terms  for  payment  of the  Offered
Price (which shall be payable solely in U.S.  currency,  rather than in property
of any other kind or nature),  which shall specify any amount payable in cash or
by certified  funds at closing as well as the  portion,  if any, of the purchase
price to be deferred and evidenced by one or more promissory notes;

                              5.13.1.3  the  terms  of  any   promissory   notes
(including a stated rate of interest and a fixed payment  schedule) and security
instruments  (including  provisions for releases of portions of the Project from
the lien of such security instruments) to evidence and secure any portion of the
Offered Price which is not payable at closing;

                              5.13.1.4 the Age Restrictions described in Section
5.15; and

                              5.13.1.5  such  other   material   terms  for  the
purchase deemed relevant by the Initiating Member.

                  5.13.2  Election to  Purchase.  Within 45 days  following  the
Offering  Notice  Date,  the  Responding  Member  shall give  written  notice (a
"Reply") to the Initiating  Member stating whether the Responding Member desires
to  purchase  the  Initiating  Member's  entire  interest  in the  Company  (the
"Available Interest"). Failure to provide a Reply within the 45 day period shall
be deemed an election not to purchase the Available Interest.  The date, if any,
on which the  
                                       20
<PAGE>
Responding  Member elects (or, as a result of failing to deliver a timely Reply,
is deemed to have elected) not to purchase the Available Interest is referred to
hereinafter as the  "Rejection  Date." The date, if any, on which the Responding
Member elects to purchase the Available  Interest is referred to  hereinafter as
the "Reply Date."

                  5.13.3 Terms of  Purchase.  If the  Responding  Member gives a
Reply within the prescribed 45 day period under Section 5.13.2,  stating that it
intends to purchase the Available  Interest,  the Responding Member may purchase
the Available Interest on the following terms and conditions:

                              5.13.3.1 Time for Performance. The purchase of the
Available  Interest  must close on or before the date which is 60 days after the
Reply Date. If the Responding  Member fails to close on the purchase  within the
prescribed 60 day period:  (a) the Initiating  Member's sole recourse and remedy
shall be the right to  solicit  and  accept on behalf of the  Company  offers to
purchase  the Project in  accordance  with Section  5.13.4,  and (b) the date on
which  the  prescribed  60  day  period  expires  shall  be  referred  to as the
"Expiration Date."

                              5.13.3.2   Closing   Procedure.   Closing  of  the
transfer of the  Available  Interest  pursuant to this  Section  5.13 shall take
place within 60 days of the Reply Date,  at the offices of the  Company,  and on
the specific date selected by the Responding  Member. The Company shall not make
any distributions of Net Cash Flow for the period between the Option Notice Date
and the Rejection Date, the date on which the transfer of the Available Interest
is completed,  or the Expiration Date, whichever is applicable.  At the closing,
the  Responding  Member  shall  pay to the  Initiating  Member,  in  immediately
available  funds,  the portion of the purchase price for the Available  Interest
that is payable at closing pursuant to the terms of the Offering Notice, and the
parties shall execute and deliver all documents and  instruments  required under
the terms of the Offering Notice.

                              5.13.3.3   Price.   The  purchase  price  for  the
Available  Interest  shall equal the total amount of payments and  distributions
that the  Initiating  Member would  receive  pursuant to Section  9.2.3,  if the
Company's assets were sold for cash at the sum of the Offered Price and the book
value  of  any  Company  asset  not  included  in the  Project  (such  as  cash,
receivables,  etc.),  the  Company  immediately  dissolved,  and its assets were
applied and  distributed  (without  retention of any  reserves)  in  liquidation
pursuant to the provisions of Section 9.2.3.

                              5.13.3.4 Terms of Payment.  The purchase price for
the  Available  Interest  shall  be paid in  accordance  with  the  terms of the
Offering  Notice,  against  delivery by the Initiating  Member of instruments of
assignment  sufficient  to transfer  the  Available  Interest to the  Responding
Member, free and clear of any liabilities,  liens, claims or encumbrances of any
nature. If, at the Closing,  the Initiating  Member's interest in the Company is
subject to any liability, lien, claim or encumbrance,  the Responding Member may
elect (a) to cause the  purchase  price (or a portion  thereof) to be applied to
discharge such liability, lien, claim or encumbrance,  (b) to take such interest
subject to such liability, lien, claim or encumbrance and to reduce the purchase
price  otherwise  payable  to the  Initiating  Member  by  the  amount  of  such
liability,  lien, claim or encumbrance,  or (c) if the liability, lien, claim or
encumbrance  was  created  without  the  consent of the  Responding  Member,  to
terminate the proceedings  under this Section 5.13.3 because of the 
                                       21
<PAGE>
existence of such  liability,  lien,  claim or  encumbrance.  Any portion of the
purchase  price  which  is not  payable  at  closing  shall  be  evidenced  by a
promissory  note  and  shall  be  secured  solely  by  a  first-lien  collateral
assignment of the Available Interest.  The payment schedule under the promissory
note shall be consistent in time and amount with the payments required under the
terms of the Offering Notice,  except the amount of required  principal payments
shall  equal the  amounts  specified  in the  Offering  Notice  multiplied  by a
fraction,  the  numerator  of  which is the  purchase  price  for the  Available
Interest and the  denominator  of which is the Offered  Price.  Acceleration  of
payments under the  promissory  note shall be required upon the sale of portions
of the Project by the Company,  determined in a manner consistent with the terms
of any release prices  established under the security  instruments  described in
the Offering  Notice.  The promissory note and pledge of the Available  Interest
shall be in customary  commercial form  reasonably  acceptable to the Initiating
Member.

                  5.13.4 Failure to Purchase.  If the  Responding  Member elects
not to  purchase  the  Available  Interest  (or is deemed to have so  elected by
failing to deliver a timely Reply), or if the Responding Member delivers a Reply
but thereafter  fails to complete the purchase of the Available  Interest within
the prescribed 60 day period, the Initiating Member shall be permitted (a) for a
period  of 180  days  following  the  Rejection  Date  or  Expiration  Date,  as
applicable  (such  period  being  referred to  hereinafter  as the  "Opportunity
Period"),  to solicit and accept on behalf of the Company offers to purchase the
Project on terms none of which are less  favorable to the Company than those set
forth in the Offering Notice,  and (b) to close the sale of the Project pursuant
to any offer accepted in accordance with clause (a) immediately  above, but only
if the closing occurs within 60 days after such offer was accepted.  If an offer
to purchase the Project is not accepted within the foregoing 180 day period,  of
if an offer is accepted but fails to close  within the  foregoing 60 day period,
then at any time following the expiration of the relevant period, any Member may
again  invoke the  provisions  of this  Section 5.13 if the Project has not been
sold by the Company and the Dispute with respect to a Major  Decision  still has
not been resolved;  provided that each Member shall have the right to invoke the
provisions of this Section 5.13 only two times.

                  5.13.5 Treatment of Certain  Nonconforming  Offers. If, during
the Opportunity Period, the Company receives an offer (a "Nonconforming  Offer")
to purchase  the Project and if any term of such offer is less  favorable to the
Company than any term of the Offering Notice:

                              5.13.5.1 A copy of the  Nonconforming  Offer shall
be provided to each Member,  and within 10 days  following  the receipt  thereof
(the "Refusal Date"),  each Member shall give written notice to the other Member
stating  whether  such Member  desires  the Company to accept the  Nonconforming
Offer. If the Nonconforming  Offer is unanimously  approved by the Members on or
before the Refusal  Date,  the  Company  shall sell the Project on the terms and
conditions set forth in the Nonconforming Offer.

                              5.13.5.2  If  the   Nonconforming   Offer  is  not
unanimously approved by the Members on or before the Refusal Date, any Member (a
"Willing  Member")  who gave  written  notice of its desire  for the  Company to
accept the Nonconforming Offer may submit the Nonconforming Offer as an Offering
Notice to the other  Member,  in which case,  the  Nonconforming  Offer shall be
treated for all purposes of this Agreement as a new Offering Notice to which all
provisions of this Section 5.13 shall apply.

<PAGE>
                  5.13.6  Use of  Nominee.  At the  election  of the  Responding
Member,  the purchase of all or part of the Available  Interest pursuant to this
Section 5.13 may be completed by a nominee of the  Responding  Member;  provided
that the  Responding  Member  shall  remain  liable  for all  obligations  to be
performed  by the nominee as  purchaser  of the  Available  Interest  under this
Section 5.13.

                  5.13.7  Operations of Company  Pending  Purchase of Interests.
During the pendency of any  proceedings  under Section  5.13,  the Company shall
continue its  operations in the ordinary  course of business in accordance  with
the terms and conditions of this Agreement.

         5.14 Buy/Sell Procedure.

                  5.14.1  Purpose.  This  Section  5.14 sets  forth a  procedure
pursuant  to which  either  Member  (each,  an  "Eligible  Member")  may cause a
purchase and sale of interests  in the Company  between the Eligible  Member and
the other Member.

                  5.14.2  Appraisal;  Offer to Sell or Purchase.  Subject to the
provisions of Section  5.14.12,  within 30 days  following the  conclusion of an
Opportunity  Period  during which the Project is not sold as provided in Section
5.13.4,  either  Member may cause the Company to engage a  nationally-recognized
business appraisal firm to determine the value of the business of the Company as
a going concern (the "Appraised Value") and the liquidation value of the Company
(the  "Liquidation  Value").  The  appraiser  shall  be  chosen  by  the  Member
commissioning  the  appraisal,  subject to the consent of the other Member which
consent shall not be unreasonably  withheld.  In no event shall the appraiser be
an  Affiliate  of either  Member or have  provided  services  to either  Member,
directly or indirectly,  within the 12-month period prior to its engagement. The
cost of the appraisal  shall be borne by the Company.  The Member  commissioning
the appraisal shall so notify the other Member,  and both Members shall have the
right to  participate  in the appraisal  process by providing the appraiser with
such information as the Members deem relevant,  provided that all communications
with the  appraiser  shall  involve  both  Members and no Member will contact or
communicate  with the appraiser ex parte.  In all events the appraiser  shall be
instructed to take into account the efforts made to sell the Project  during the
Opportunity  Period. The appraiser shall render its report to the Company within
30  days  of its  engagement  or  such  longer  period  as the  appraiser  shall
reasonably require. Within 30 days after the appraisal has been delivered to the
Company,  either  Member  (the  "Offeror")  may make to the  other  Member  (the
"Offeree") an offer to sell the Offeror's  entire interest in the Company to the
Offeree for the Purchase  Price  determined  in accordance  with Section  5.14.6
below,  which shall be coupled  with an offer to purchase the  Offeree's  entire
interest in the Company for the Purchase  Price  determined  pursuant to Section
5.14.6  below.  The  offer  described  in this  Section  5.14.2 is  referred  to
hereinafter as an "Offer to Sell or Purchase." Once given,  the Offer to Sell or
Purchase may not be revoked or altered by the Offeror.  The terms and conditions
for the  purchase  and  sale by the  Offeror  and the  Offeree  (other  than the
Purchase  Price,  which  shall be  determined  under  Section  5.14.6)  shall be
identical irrespective of which Member is the purchaser pursuant to this Section
5.14.2.  The  institution  of the  appraisal  process  shall  not  obligate  the
initiating Member to become an Offeror pursuant to this Section 5.14.
                                       23
<PAGE>
                  5.14.3  Contents  of Offer to Sell or  Purchase.  The Offer to
Sell or Purchase shall include the following:

                              5.14.3.1  a Stated  Value (as  defined  in Section
5.14.6  below)  which  forms the basis of the  Purchase  Price for the  Member's
interest in the Company;

                              5.14.3.2  the terms for  payment  of the  Purchase
Price for the Member's interest in the Company (which shall be payable solely in
U.S. currency, rather than in property of any other kind or nature), which shall
specify any amount  payable in cash or by certified  funds at closing as well as
the portion,  if any, of the Purchase  Price to be deferred and evidenced by one
or more promissory notes;

                              5.14.3.3   forms  of  promissory   notes  and  any
security  instruments  to evidence and secure any portion of the Purchase  Price
for the Member's interest in the Company which is not payable upon Closing;

                              5.14.3.4 the Age Restrictions described in Section
5.15;

                              5.14.3.5  forms of  instruments  which  impose any
operating  restrictions  and covenants  that will apply to the Company until the
Purchase Price for the Member's interest in the Company is paid in full;

                              5.14.3.6  forms of any  releases,  indemnities  or
similar agreements to be delivered by the Members at Closing;

                              5.14.3.7  forms of  instruments  pursuant to which
the interest in the Company will be conveyed or assigned; and

                              5.14.3.8  such all  other  material  terms for the
purchase and sale of interests in the Company deemed relevant by the Offeror.

Each of the instruments and documents referred to above shall be in commercially
reasonable   form  and  shall  be  prepared  in  good  faith  by  the   Offeror.
Notwithstanding  the  terms  set  forth in the  Offer to Sell or  Purchase,  the
selling  Member  shall be obligated to convey its interest in the Company to the
purchasing  Member  free  and  clear  of  any  liabilities,   liens,  claims  or
encumbrances,  other than any liabilities,  liens,  claims or encumbrances taken
subject to or being  assumed by the  purchasing  Member as  outlined  in Section
5.14.10.

                  5.14.4 Response. The Offeree shall elect in writing, within 30
days of its receipt of the Offer to Sell or Purchase, either:

                              5.14.4.1  to  sell  its  entire  interest  in  the
Company  to the  Offeror  in  accordance  with the terms of the Offer to Sell or
Purchase; or

                              5.14.4.2 to  purchase  from the Offeror its entire
interest  in the  Company in  accordance  with the terms of the Offer to Sell or
Purchase.

<PAGE>
The  Offeree's   election  pursuant  to  this  Section  5.14.4  is  referred  to
hereinafter as the "Response." If the Offeree fails to issue the Response within
the  required  30 day  period,  the  Offeree  shall be deemed to have  given the
Response on the last day of such period, electing to sell its entire interest in
the Company to the Offeror. The date on which the Response is actually given (or
deemed to have been given,  if the Offeree  fails to give a timely  Response) is
referred to hereinafter as the "Response Date."

                  5.14.5  Effect of  Response.  If the  Offeree  makes  (or,  by
failing to issue a Response,  is deemed to have made) the election  described in
Section  5.14.4.1,  the Offeror  shall be obligated  to purchase  the  Offeree's
entire  interest in the Company (and the Offeree shall be obligated to sell such
interest)  on the  terms  and  conditions  set  forth  in the  Offer  to Sell or
Purchase,  for the Purchase Price determined  pursuant to Section 5.14.6 hereof.
If the Offeree  makes the election  described in Section  5.14.4.2,  the Offeree
shall be obligated to purchase the Offeror's entire interest in the Company (and
the  Offeror  shall  be  obligated  to sell  such  interest)  on the  terms  and
conditions  set forth in the Offer to Sell or Purchase,  for the Purchase  Price
determined pursuant to Section 5.14.6 hereof.

                  5.14.6  Purchase  Price.  The  purchase  price for a  Member's
interest in the Company  pursuant to this  Section 5.14 (the  "Purchase  Price")
shall equal the total  amount of  payments  and  distributions  that such Member
would receive pursuant to Section 9.2.3, if the Company was sold for cash at the

Member's  interest in the Company is subject to any  liability,  lien,  claim or
encumbrance, the purchasing Member may elect (a) to cause the Purchase Price (or
a portion  thereof) to be applied to discharge such  liability,  lien,  claim or
encumbrance, (b) to take such interest subject to such liability, lien, claim or
encumbrance  and to reduce the Purchase Price  otherwise  payable to the selling
Member by the amount of such liability,  lien,  claim or encumbrance,  or (c) if

without  the  consent  of the  purchasing  Member,  to  terminate  the  buy-sell
proceedings  under this Section 5.14 because of the existence of such liability,
lien, claim or encumbrance.

                  5.14.11  Failure to Close. If the Member which is obligated to
purchase the interest of the other Member  pursuant to the terms of this Section
5.14 fails for any reason (other than as set forth in Section  5.14.10(c) above)

"Disqualified  Member"),  the  Disqualified  Member shall be liable to the other
Member for all costs (including, without limitation, attorneys' and accountants'
fees),  incurred by it in  connection  with the  proceedings  under this Section
5.14. In addition:  (a) the Disqualified Member shall not be permitted to become

                  5.14.13 Use of  Nominee.  At the  election  of the  purchasing
Member, the purchase of the selling Member's interest in the Company pursuant to
this  Section  5.14 may be  completed  by a nominee  of the  purchasing  Member;
provided that the purchasing  Member shall remain liable for all  obligations to
be performed by the nominee under this Section 5.14.

         5.15 Age  Restrictions.  If the Project has not been  subjected  to Age
Restrictions  (as  hereinafter  defined) at any time that either Member acquires
the other Member's interest in the Company pursuant to the provisions of Section
5.13,  Section 5.14 or Section 8.5 or if the Project is sold pursuant to Section
5.13,  then on or before the  closing of the  transfer of the  interest  (or the
Project, as applicable), the acquiring Member shall cause Age Restrictions to be
recorded  against  the  Property.  As  used  in  this  Section,  the  term  "Age
Restrictions"  shall mean a recorded  declaration  of covenants,  conditions and
restrictions (i) which subjects the Property to age restrictions  qualifying for
the "55 or older" exemption of the Fair Housing Act, 42 U.S.C. ss. 3607(b)(2)(C)
and applicable rules, regulations and policies promulgated thereunder,  (ii) the
form of which has been  approved by the  non-acquiring  Member,  which  approval

hereinafter  referred to as a "North Property  Developer")  owning or developing
all  or  part  of  the  approximately  1,000  acres  of  real  property  located
immediately  north of the Property (as  described in that certain  Third Amended

prior written consent of each North Property Developer,  which consent shall not
be unreasonably withheld.

         5.16  Restrictive  Covenants.  SunPower  agrees  that  (a) it will  not
develop or apply for any governmental  approval  required for the development of
an  age-restricted  community  on any portion of the real  property  depicted on
Exhibit A, other than the Property (the "Retained  SunPower Land"),  for so long
as the  Company  is  actively  developing  an  age-restricted  community  on the
Property,  and (b) it will not make any material change to the development  plan
for the  Retained  SunPower  Land,  as set forth on Exhibit A, without the prior
written consent of UDC. The foregoing  covenants and  restrictions in clause (a)
and clause (b) above shall  expire upon the first to occur of (i) 15 years after
the date of this  Agreement,  or (ii)  sale of 90% of the  approved  residential
units within the Property.  SunPower also will cause Power North L.L.C.  ("Power
North"),  an Arizona limited liability company that is an Affiliate of SunPower,
to comply with the  restrictions in clause (a) (but not clause (b)) above on the
same basis as SunPower with respect to the real  property  depicted on Exhibit B
(the "Power North Land").  On or before January 15, 1998,  SunPower shall record
instruments in a form  satisfactory  to SunPower and UDC subjecting the SunPower
Retained  Land and the Power North Land to the  covenant set forth in clause (a)
above  (and  prior to such  recordation  SunPower  shall  obtain  the  necessary
signatures  thereon by the owner of such Land and any  lender  holding a lien on
such Land).  Upon any sale of all or any portion of the SunPower  Retained  Land
(other than to the end user of a  residential  lot),  SunPower  shall notify the
purchaser  of the  covenant  set forth in clause (b) above and shall  cause such
covenant (and the indemnity obligation set forth below) to be assumed in writing
by the purchaser (which  assumption shall include a covenant by the purchaser to
cause  subsequent  purchasers  to assume the covenant set forth in clause (b) on
the same basis as the  purchaser).  For  purposes of Section  5.16(b),  the word
"material"  shall mean only those changes which  reasonably could be expected to
have a material  negative  financial  impact on the  Company's  development  and
marketing of the Property.  If any  disagreement  with respect to any matter set
forth in this Section 5.16 (including,  without  limitation,  whether a proposed
change to the development  plan for the Retained  SunPower Land is material) has
not been  resolved  within 30 days  following a written  request for approval of
such matter by the Members  whose  consent is  required  hereunder,  such matter
shall be a Dispute that is subject to  resolution in the same manner as provided
in Section 5.7 hereof.  SunPower shall  indemnify,  defend and hold harmless the
Company from and against any liability,  damage,  cost, expense,  loss, claim or
judgment  incurred  by the  Company  as a result  of  SunPower's  breach  of any
obligation under this Section 5.16.

Company's  place of business,  setting forth a true and accurate  account of all

Company.  The costs and expenses  (including  employee costs) incurred by UDC in
maintaining  such books and  records  shall be paid or  reimbursed  to it by the
Company to the extent  provided in Section  5.11.  Any Member or its  designated
representative  shall have the right, at any reasonable  time, to have access to
and inspect,  copy and audit the  contents of such books or records.  Unless the
Executive  Committee  determines  otherwise,  the Company's  financial books and
records  shall be audited  annually at the expense of the Company,  by a firm of
independent certified  accountants selected by the Executive Committee,  and the
costs of the audit shall be treated as an Approved  Expense for purposes of this
Agreement.
                                       27

         6.2 Reports. Within 45 days following the end of each calendar quarter,
UDC  shall  furnish  each  Member  with:  (a) cash  basis  financial  statements

of the Executive Committee.

         6.4 Bank  Accounts.  UDC shall open and maintain in the Company's  name
one or more bank  accounts,  into which shall be deposited all Company funds and
only Company  funds.  The funds in the Company's  bank accounts may be withdrawn
solely to pay Approved  Expenses and those other expenses for which Member Loans
may be funded  pursuant to Section 2.10.1 hereof.  Withdrawals  from any Company
bank account may be made by checks or other withdrawal forms signed by UDC.

         SECTION 7.  AMENDMENTS

instrument signed by the Members.

         SECTION 8.  TRANSFER OF COMPANY INTERESTS; NEW MEMBERS

         8.1  General.  No  Member  shall  sell,  assign,  pledge,  hypothecate,
encumber or otherwise  voluntarily  transfer by any means whatever  ("Transfer")
all or any portion of its interest in the Company (or permit any Person directly
or  indirectly  holding any interest in such Member  directly or  indirectly  to
Transfer  any part of such  interest),  except for  Transfers  (a)  approved  in
writing by all Members,  or (b) permitted under Section 8.2 hereof. A transferee
of a Member's  interest in the Company will be admitted as a Substituted  Member
only  pursuant to Section  8.4 hereof.  Any  purported  Transfer  which does not
comply with the  provisions  of this  Section 8 shall be void and of no force or
effect.

         8.2 Permitted Transfers.  Notwithstanding  Section 8.1 hereof, a Member
may permit direct and indirect  Transfers of interests in such Member so long as
such Transfers do not result in a Change in Control of such Member.

         8.3  Assignee of Member's  Interest.  If,  pursuant to a Transfer of an
interest in the Company by operation of law and without violation of Section 8.1
hereof (or  pursuant to a Transfer  that the  Company is  required to  recognize
notwithstanding any contrary provisions of this Agreement), a Person acquires an
interest in the Company, but is not admitted as a Substituted Member pursuant to
Section 8.4 hereof, then, subject to Section 8.5 hereof, such Person:
                                       28
<PAGE>
                  8.3.1 shall be treated as an assignee of a Member's  interest,
as provided in the Act;

                  8.3.2 shall have no right to  participate  in the business and
affairs  of the  Company  or to  exercise  any  rights  of a Member  under  this
Agreement or the Act; and

                  8.3.3  shall  share in  distributions  from the  Company  with
respect  to the  transferred  interest,  on the same  basis as the  transferring
Member.

         8.4  Substituted  Members.  No Person taking or acquiring,  by whatever
means,  the  interest  of any  Member  in the  Company  shall be  admitted  as a
substituted  Member in the Company (a "Substituted  Member") without the written
consent of all Members, which consent may be withheld or granted in the sole and
absolute discretion of each Member.

         8.5 Option to Purchase.

                  8.5.1 General. Upon any Transfer of an interest in the Company
in  violation  of this  Section 8 or upon a Transfer of any interest in a Member
that is prohibited by this Agreement (a "Triggering  Event"), the Member to whom
a Triggering  Event has not occurred (the "Option Member") shall have the right,
but not the  obligation,  to purchase  the entire  interest in the Company  (the
"Option  Interest")  of the Member to whom the  Triggering  Event  occurred (the
"Selling Member"), on the terms and conditions set forth in this Section 8.5.

                  8.5.2  Election.  An Option  Member may  invoke the  valuation
procedure of Section 8.5.3 by giving written notice (the "Valuation  Notice") to
the Selling  Member (or, if  applicable,  its  representatives,  successors,  or
assigns) and to each other Option Member,  if any, at any time within six months
following the Option Member's actual knowledge of the Triggering Event.

                  8.5.3 Valuation  Procedure.  For a period of 60 days following
the  Valuation  Notice,  the  Option  Member  and the  Selling  Member  (or,  if
applicable,  the  representatives,  successors or assigns of the Selling Member)
shall  negotiate in good faith to determine  the fair market value of all of the
Company's  assets,  taken  as a  whole,  exclusive  of  any  goodwill  or  other
intangible  asset that does not have a book value for  accounting  purposes (the
"Assets").  If the parties  are unable to agree on the fair market  value of the
Assets within the prescribed  60-day period,  the parties shall,  within 15 days
following  the end of such 60-day  period,  unanimously  select an  appraiser or
appraisers to determine the fair market value of the Assets.  If the parties are
unable to agree on an  appraiser  or  appraisers  within  the  foregoing  15-day
period,  then at the  election of any party,  the  selection  of an appraiser or
appraisers  shall be submitted to dispute  resolution in accordance with Section
5.7 hereof.  Following his or their selection,  the appraiser(s) shall determine
as soon as  practicable  the fair  market  value  of the  Assets  assuming,  for
purposes of determining such value, that the Assets are liquidated in an orderly
manner over a period of six months.  The parties'  agreement as to value,  or if
applicable,  the  appraiser's  (appraisers')  determination  of  value  shall be
binding on all parties for purposes of this Agreement.  The date of the parties'
agreement on the value of the Assets,  or, if applicable,  the date of the final
appraisal  
                                       29
<PAGE>
report(s),  is referred to hereinafter  as the  "Valuation  Date." All appraisal
costs and costs under Section 5.7 shall be borne by the Selling Member.

                  8.5.4  Purchase  Price.  The  purchase  price  of  the  Option
Interest shall equal 95% of the amount the Selling Member would receive pursuant
to Section  9.2.3 if the Assets  were sold for cash at their fair  market  value
(determined  in  accordance  with  Section  8.5.3),   the  Company   immediately
dissolved, and its assets were applied and distributed (without retention of any
reserves) in liquidation pursuant to Section 9.2 hereof.

                  8.5.5  Exercise  of  Right.   Within  60  days  following  the
Valuation  Date,  the Option  Member  shall give  written  notice to the Selling
Member  stating  whether  such  Option  Member  desires to  purchase  the Option
Interest.  The Option Member shall thereafter be entitled to purchase the Option
Interest  by  delivering  to the  Selling  Member  (or,  if  applicable,  to the
representatives,  successors  or  assigns  of the  Selling  Member)  the  Option
Member's negotiable  promissory note (the "Note") in a principal amount equal to
the purchase  price  determined  under  Section  8.5.4,  payable in equal annual
installments of principal together with annual payments of interest at the Prime
Rate, over a period not to exceed five years, with the first installment due and
payable  one  year  from  the date of sale.  The  Note  shall  be  secured  by a
collateral assignment of the Option Interest acquired by the Option Member, in a
commercially  reasonable form determined by the Option Member. The Note shall be
due and  payable  in full at such  time  as the net  fair  market  value  of the
Company's  remaining  assets (as reasonably  determined by the Option Member) is
less than 200% of the then outstanding balance of the Note.

                  8.5.6 Deliveries by Selling Member.  Upon receipt of an Option
Member's  Note,  the Selling  Member (or, if  applicable,  its  representatives,
successors or assigns) shall deliver to the Option Member an executed assignment
of the Option Interest to be acquired by the Option Member, sufficient to convey
such  interest to the Option  Member free and clear of any  liabilities,  liens,
claims or encumbrances,  except those taken subject to by the Option Member,  as
provided below.

                  8.5.7 Assumption and Release.  In connection with the purchase
of any portion of the Option Interest hereunder, the Option Member shall release
the  Selling  Member  from and  assume,  as  appropriate,  such  Company-related
obligations  and  guarantees as shall relate to the  transferred  portion of the
Option Interest and agree to indemnify and hold harmless the Selling Member with
respect to all such obligations and guarantees.

                  8.5.8 Closing  Adjustments.  If the Option Interest is subject
to any liability, lien, claim or encumbrance, the Option Member may elect (a) to
cause the purchase price (or a portion  thereof) to be applied to discharge such
liability,  lien,  claim or encumbrance,  or (b) to take the relevant portion of
the Option Interest subject to such liability, lien, claim or encumbrance and to
reduce the purchase price otherwise  payable by the Option Member to the Selling
Member by the amount of such liability, lien, claim or encumbrance.

                  8.5.9 Use of Nominee.  At the election of a Option Member, the
purchase of all or part of the Option Interest  pursuant to this Section 8.5 may
be  completed  by a  nominee  of the  
                                       30
<PAGE>
Purchasing  Member,  in which case,  the  obligations of the Option Member under
this  Section  8.5 shall be  performed  by the  nominee  rather  than the Option
Member.

         8.6 Distributions in Respect of Transferred Interests.  If any interest
in the Company is transferred  during any accounting  period in compliance  with
the  provisions  of this Section 8, all  distributions  on or before the date of
such Transfer shall be made to the transferor,  and all distributions thereafter
shall be made to the transferee.

                  9.2.2 Effect of Filing.  After the dissolution of the Company,
the  Company  shall  cease to carry on its  business,  except  insofar as may be
necessary  for  the  winding  up of its  business,  but the  Company's  separate
existence shall continue until articles of termination  have been filed with the
Arizona Corporation Commission or until a decree dissolving the Company has been
entered by a court of competent jurisdiction.

                  9.2.3  Liquidation  and  Distribution  of  Assets.   Upon  the
dissolution  of the  Company,  the  remaining  Member(s),  or a  court-appointed
trustee,  if there is no  remaining  Member,  shall  take  full  account  of the
Company's  liabilities  and  assets,  and such  assets  shall be  liquidated  as
promptly as is  consistent  with  obtaining the fair value  thereof.  During the
period of liquidation, the business and affairs of the Company shall continue to
be governed by the  provisions  of this  Agreement,  with the  management of the
Company   continuing  as  provided  in  Section  5  hereof.  The

         1.10 Independent Activities.

                  1.10.1  The  General  Scope  of  Independent  Activities.  The
Members hereby  expressly agree and acknowledge that each of the Members (either
directly, or through its Affiliates, officers, directors, members, shareholders,
agents and  employees)  is involved in  transactions,  investments  and business
ventures and undertakings of every nature,  which include,  without  limitation,
activities  which are not  associated  in any manner with real estate as well as
the ownership, construction,  development, marketing, sale and operation of real
property and improvements of every type and nature thereon (all such investments
and activities being referred to hereinafter as the "Independent Activities").

                  1.10.2 Specific Independent  Activities.  Without limiting the
generality of Section 1.10.1,  the Members  acknowledge that (a) the Independent

                  1.10.3   Waiver  of  Rights   with   Respect  to   Independent
Activities.  Nothing in this  Agreement  shall be construed to: (a) prohibit any
Member  or its  Affiliates  from  continuing,  acquiring,  owning  or  otherwise
participating  in any Independent  Activity that is not owned or operated by the
Company,  even if such Independent Activity is or may be in competition with the
Company;  or (b) require any Member to allow the Company or the other  Member to
participate in the ownership or profits of any such Independent Activity. To the
extent any Member would have any rights or claims  against the other Member as a
result of the Independent  Activities of such Member or its Affiliates,  whether
arising by  statute,  common law or in equity,  the same are hereby  waived with
respect  to the  operation  of the  Company  and the  marketing  and sale of the
Project.

                  1.10.4 Limitation on Company Opportunities. Each Member hereby
represents and warrants to the other Member that it has not been offered,  as an
inducement to enter into this Agreement, the opportunity to participate with the
other Member in the ownership or profits of any Independent Activity of any kind
whatsoever of such Member or its Affiliates.  The Members expressly  acknowledge
that  the  opportunities  of the  Company  shall  be  limited  to the  Permitted
Activities  with respect to the  Property and shall not extend to any  property,
investment or activity other than the Permitted  Activities  conducted solely on

                  UDC                 50%

At each time (if any)  that the  percentage  interests  of UDC and  SunPower  in
UDC/SunPower  L.L.C.  are adjusted as set forth in Section 2.7 of the  Operating
Agreement  of  UDC/SunPower  L.L.C.  the Members'  Percentage  Interests in this
Company  shall  be  adjusted  so  that at all  times,  the  Members'  Percentage
Interests in UDC/SunPower L.L.C. and in this Company are identical.

<PAGE>
         2.4 Additional Capital Contributions.

                  2.4.1 Intent to Finance Approved Expenses. If, during the term
of the Company,  funds available to the Company are insufficient to pay Approved
Expenses when due, the Executive  Committee shall use its best efforts to obtain
a loan from a third party lender (or from a Member,  if no third party lender is
willing  to lend  sufficient  funds to the  Company on terms  acceptable  to the
Executive Committee) to fund such insufficiency.

                  2.4.2  Inability to Obtain  Financing;  Request for Additional
Capital Contributions.  If the Executive Committee is unable to secure financing
to pay such Approved  Expenses on terms  acceptable to the Executive  Committee,
then the Executive Committee shall send a written request to the Members and the
Members  shall  contribute to the Company,  in  proportion  to their  Percentage
Interests,  as "Additional  Capital  Contributions," an amount equal to any such
insufficiency.  Additional Capital Contributions  required under the immediately
preceding  sentence  shall be due and payable in cash within 15 days following a
written  request  therefor  from the  Executive  Committee.  Additional  Capital
Contributions shall be applied by the Company solely to pay Approved Expenses.

                  2.4.3 Limitation on Additional  Capital  Contributions.  In no
event shall Additional Capital  Contributions exceed $5,000 in the aggregate for
UDC or $5,000 in the aggregate for SunPower without the prior written consent of
both Members.

                  2.4.4  Failure of Executive  Committee  to Request  Additional
Capital  Contributions.  If the Executive  Committee fails to request Additional
Capital  Contributions  to fund any Approved  Expenses  after demand to do so is
made upon the  Executive  Committee  in  writing by any  Member,  any Member may
request Additional Capital Contributions pursuant to this Section 2.4.

         2.5 Limitations Pertaining to Capital Contributions.

                  2.5.1 Return of Capital.  Except as otherwise provided in this
Agreement,  no Member shall withdraw any Capital  Contributions  or any money or
other property from the Company without the written consent of the other Member.
Under circumstances  requiring a return of any Capital Contributions,  no Member
shall have the right to receive  property  other  than  cash,  unless  otherwise
specifically agreed in writing by the Members at the time of such distribution.

                  2.5.2 No  Interest  or Salary.  No Member  shall  receive  any
interest,  salary or drawing  with respect to its Capital  Contributions  or its
Capital  Account or for services  rendered on behalf of the Company or otherwise
in its  capacity as a Member,  except as  otherwise  expressly  provided in this
Agreement.

                  2.5.3 Liability of Members.  Except as agreed upon in writings
signed by the  Members,  no Member  shall be liable for the debts,  liabilities,
contracts or any other obligations of the Company.  Except as agreed upon by the
Members, and except as otherwise provided by Section 29-651 of the Act or by any
other  applicable  state law,  the  Members  shall be liable  only to make their
Capital  Contributions to the extent provided in Sections 2.3 and 2.4 hereof and
no 
                                       4
<PAGE>
Member shall be required to make any other Capital  Contributions or to loan any
amounts to the  Company.  No Member shall have any  personal  liability  for the
repayment of the Capital Contributions or loans of the other Member.

                  2.5.4  No  Third  Party  Rights.  Nothing  contained  in  this
Agreement  is intended or will be deemed to benefit any creditor of the Company,
and no  creditor  of the  Company  will be  entitled  to require  the  Executive
Committee or any Member to solicit or demand Additional Capital Contributions.

                  2.5.5  Withdrawal.  Except as provided in Section 8 hereof, no
Member may voluntarily or  involuntarily  withdraw from the Company or terminate
its interest therein without the prior written consent of the other Member.  Any
Member who withdraws from the Company in breach of this Section 2.5.5:

                              2.5.5.1  shall  be  treated  as an  assignee  of a
Member's interest, as provided in the Act;

                              2.5.5.2 shall have no right to  participate in the
business  and affairs of the Company or to exercise any rights of a Member under
this Agreement or the Act; and

                              2.5.5.3  shall,  subject  to Section  8.5  hereof,
continue to share in  distributions  from the  Company,  on the same basis as if
such  Member had not  withdrawn,  provided  that any damages to the Company as a
result of such  withdrawal  shall be offset against amounts that would otherwise
be distributed to such Member. The right to share in distributions granted under
this Section 2.5.5 shall be in lieu of any right the  withdrawn  Member may have
under the Act to  receive a  distribution  or  payment  of the fair value of the
Member's interest in the Company.

         2.6 Failure to Contribute.

                  2.6.1  Default  Notice.  If  any  Member  (a  Non-Contributing
Member") fails to fund its Additional Capital Contributions when due, any Member
which has funded its Additional Capital Contributions (a "Contributing  Member")
may give  written  notice (the  "Contribution  Notice") to the  Non-Contributing
Member,   setting  forth  the  amount  of  the  delinquent   Additional  Capital
Contribution (the "Deficit Amount"). From and after the Contribution Notice, the
Non-Contributing  Member's  Representatives  shall  cease to be  members  of the
Executive  Committee (with the Contributing  Member's  Representatives,  if any,
serving as the sole members of the Executive  Committee).  The rights  suspended
under the  immediately  preceding  sentence  shall be  reinstated  only upon the
Non-Contributing  Member's  funding of the Deficit  Amount or  repayment  of the
applicable Default Loan.

                  2.6.2 Default Remedies.  If the Non-Contributing  Member fails
to contribute  the Deficit  Amount to the Company  within 15 days  following the
Contribution Notice, the Nondefaulting Member may elect to:

                              2.6.2.1 recover from the Company the entire amount
of  its   Additional   Capital   Contribution   made  at  the   time   when  the
Non-Contributing Member failed to fund its Additional Capital Contribution; or
                                       5
<PAGE>
                              2.6.2.2  fund as a loan (a "Default  Loan") to the
Non-Contributing  Member,  all or part of the Deficit Amount by advancing  funds
directly to or for the account of the Company.

The  foregoing  remedies  shall  be  treated  for all  purposes  as  concurrent,
nonexclusive remedies.

                  2.6.3 Election by  Contributing  Member to Make Default Loans.
Within 30 days following the Contribution Notice (if the Non-Contributing Member
still has not funded its Deficit Amount),  the Contributing Member shall provide
written notice to the  Non-Contributing  Member stating whether the Contributing
Member  desires to make a Default Loan. The  Non-Contributing  Member may make a
Default  Loan at any time  within 60 days  following  the  Contribution  Notice.
Default Loans shall be payable on the terms and  conditions set forth in Section
2.6.4. The failure of a Contributing  Member to give a Contribution Notice under
this  Section  2.6.3  shall not  impair or  otherwise  affect  any other  remedy
available to the Contributing Member under Section 2.6.2 hereof.

                  2.6.4 Terms of Default Loans.  Default Loans shall bear simple
(noncompounded) interest at the greater of (a) the Prime Rate plus 1% per annum,
or (b) 15% per  annum;  provided  that any  Arizona  laws  limiting  the rate of
interest  that may be legally  charged  with  respect to a Default Loan shall be
taken into  account  and, if  applicable,  the rate of  interest  charged on the
Default Loans shall be reduced to the maximum rate of interest permitted by such
laws.

                  2.6.5 Accounting. The Non-Contributing Member shall be treated
as having made an Additional  Capital  Contribution in the amount of any Default
Loan made to it by the Contributing Member pursuant to Section 2.6.3 hereof.

                  2.6.6  Treatment of  Distributions.  While any Default Loan is
outstanding,  all payments and cash distributions to which the  Non-Contributing
Member is entitled  pursuant to Section  3.1, 5.8 or 9.2 hereof shall be paid to
the Contributing Member, first, in payment of the unpaid interest outstanding on
its Default Loan, and then in payment of the  outstanding  principal  balance on
its Default Loan, until the Default Loan has been paid in full.  Amounts paid to
the Contributing  Member pursuant to the preceding  sentence shall be treated as
payments  or  distributions  to the  Non-Contributing  Member,  as  appropriate.
Amounts  treated as  payments  shall  reduce the  amounts,  if any,  owed by the
Company to the  Non-Contributing  Member,  and amounts treated as  distributions
shall be debited to the Non-Contributing  Member's Capital Account, and shall be
treated for all  purposes of this  Agreement as though all such amounts had been
paid or distributed directly to the  Non-Contributing  Member under Section 3.1,
5.8 or 9.2, as applicable.

         SECTION 3.  DISTRIBUTIONS

         3.1   Distributions.   Except  as   provided   in   Section  9  hereof,
distributions of Net Cash Flow, if available,  shall be made to the Members on a
quarterly basis in proportion to their Percentage Interests.
                                       6

         SECTION 4. TAX ALLOCATIONS

         4.1 General Allocation Rules.

                  4.1.1 General  Allocation  Rule.  For each taxable year of the
Company,  after the  application  of Section 4.2 hereof,  Profits  and/or Losses
shall be  allocated  to the  Members  in a manner  which  causes  each  Member's
Adjusted  Capital  Account Balance to equal the amount that would be distributed
to  such  Member   pursuant  to  Section  9.2.3.2  hereof  upon  a  hypothetical
liquidation of the Company in accordance with Section 4.1.2 below.

                  4.1.2  Hypothetical  Liquidation  Defined.  In determining the
amounts  distributable  to the Members under Section 9.2.3.2 upon a hypothetical
liquidation,  it shall be presumed that (a) all of the Company's assets are sold
at their  respective  values  reflected  on the books of account of the Company,
determined in accordance  with Code Section  704(b) and  Regulations  thereunder
("Book  Value"),  without  further  adjustment,  (b) payments to any holder of a
nonrecourse debt are limited to the Book Value of the assets securing  repayment
of such debt,  and (c) the  proceeds of such  hypothetical  sale are applied and
distributed in accordance with Section 9.2 hereof.

                  4.1.3 Special Loss Allocation. If the Company incurs Losses at
any time when the Members'  Adjusted  Capital Account Balances have been reduced
to or below zero, such Losses shall be allocated to the Members in proportion to
their Percentage Interests.

                  4.1.4  Special  Profits  Allocation.  If  the  Company  incurs
Profits at any time when the Members' Adjusted Capital Account Balances are less
than zero and the hypothetical  liquidation described in Section 4.1.2 would not
result in any  distributions  to the Members,  Profits shall be allocated to the
Members in proportion to their negative Adjusted Capital Account Balances, until
such negative balances have been eliminated.

                  4.1.5 Item Allocations. To the extent the Executive Committee,
upon consultation with the Company's accountants, determines that allocations of
Profits and/or Losses over the term of the Company are not likely to produce the
Adjusted Capital Account Balances  intended under this Section 4.1, then special
allocations  of income,  gain,  loss  and/or  deduction  shall be made as deemed
necessary by the Executive  Committee to achieve the intended  Adjusted  Capital
Account Balances.

         4.2 Regulatory and Curative  Allocations.  The allocations set forth in
Section 4.1 are intended to comply with the requirements of Regulations Sections
1.704-1(b)  and  1.704-2.  If the Company  incurs  "nonrecourse  deductions"  or
"partner  nonrecourse  deductions,"  or if there is any change in the  Company's
"minimum  gain" or "partner  nonrecourse  debt minimum gain," as defined in such
Regulations,  or if  the  Executive  Committee  determines  that  the  foregoing
allocations fail for any reason to comply with the  Regulations,  the allocation
of  Profits,  Losses and items  thereof to the  Members  shall be  modified in a
reasonable  manner deemed  necessary or advisable by the Executive  Committee to
comply  with the  Regulations;  provided  that to the  extent  permitted  by the
Regulations,  all "nonrecourse  deductions" shall be allocated to the Members in
proportion to their Percentage Interests.
                                       7
<PAGE>
         4.3 Capital  Account.  A Capital  Account shall be maintained  for each
Member in accordance with the Regulations, under uniform policies and procedures
established by the Executive Committee.

         SECTION 5. MANAGEMENT

         5.1 Management of Company.

                  5.1.1 General. Except as specifically provided in Section 5.5,
the right to manage, control and conduct the business and affairs of the Company
shall be vested solely in the Executive Committee.

                              5.1.1.1  Executive  Committee.  The Members  shall
establish  a  committee  (the  "Executive  Committee"),  which  (subject  to the
provisions   of  Section   2.6.1)   shall   consist   of  four   representatives
(individually, a "Representative" and collectively the "Representatives") to act
on behalf of the Members on all matters relating to the Company.  SunPower shall
designate two Representatives  (with its initial  Representatives  being John W.
Graham and James C. Hoselton) and UDC shall designate two Representatives  (with
its initial  Representatives  being Robert  McLaughlin  and Darrell  Bolognesi).
Representatives  may be  changed  upon  written  notice  from the  Member  which
appointed the Representative who is being changed to the other Member,  provided
that all successor Representatives of a Member shall be reasonably acceptable to
the other  Member.  Each of SunPower and UDC may appoint one or more  alternates
for  the  Representative(s)   appointed  by  it,  which  alternate(s)  shall  be
reasonably  acceptable  to the other Member and shall have all the powers of the
initially  designated  Representative(s)  in his (their) absence or inability to
serve.

                              5.1.1.2  Meetings.  A  meeting  of  the  Executive
Committee may be called by any Member or its Representatives upon written notice
delivered not less than five business days before the meeting, setting forth the
time and general purpose of the meeting. Unless the Representatives collectively
agree otherwise  (which agreement may include an arrangement to hold meetings by
telephone conference), all meetings shall be held in the offices of the Company.
Representatives may bring to any meeting such employees,  agents,  professionals
and  advisors  as they deem  necessary  or  appropriate  to assist  them at such
meeting.

                              5.1.1.3 Decisions.  All decisions of the Executive
Committee shall require unanimous agreement of the Representatives, which may be
stated in person or given by proxy or pursuant to written  agreements  signed by
the  Representatives  (with  or  without  holding  a  meeting).  Subject  to the
provisions  of Section 5.5, any Dispute (as defined in Section 5.3) with respect
to  decisions  by the  Executive  Committee  shall be subject to  resolution  in
accordance with Section 5.4.

                              5.1.1.4 Required Effort. The Representatives shall
devote such time to the Company and its  business as is  appropriate  to conduct
the business of the Executive Committee in an effective manner, but shall not be
required to devote  their full time  efforts to the  Executive  Committee or the
Company.

                              5.1.1.5 Indemnity; Insurance. The liability of the
Representatives  shall be limited, and the Representatives  shall be indemnified
for their acts to the extent  provided in Section 5.7 hereof.  Either Member may
procure (at its sole expense)  errors and omissions  insurance  coverage for its
Representatives,  for policy  limits  and risks  reasonably  acceptable  to such
Member.

                  5.1.2  Assignment  and  Delegation  of Duties.  The  Executive
Committee shall apportion responsibility for the management and operation of the
Company   between   the   Members  on  a   reasonable   basis,   such  that  the
responsibilities and duties allocated to the Members are commensurate with their
respective ownership interests in the Company. The responsibilities allocated to
each Member shall include specific duties,  privileges,  powers and authority as
deemed  necessary  by the  Executive  Committee  to  further  the  business  and
operations of the Company.

                  5.1.3 Duties and Authority of Members.

                              5.1.3.1  Right  and  Duty  to  Complete  Allocated
Responsibilities.  Subject  to the  Approved  Budgets,  and  to  any  additional
limitations  that may be imposed from time to time by the  Executive  Committee,
each Member shall have the right and the duty to exert  reasonable  efforts in a
prompt and  businesslike  manner to do,  accomplish and complete,  in accordance
with this  Agreement,  all  responsibilities  and duties  allocated to it by the
Executive Committee.

                              5.1.3.2 Standard of Performance. Each Member shall
exercise such skill and care in fulfilling its  responsibilities and duties as a
prudent developer with experience in developing  projects like the Project would
exercise in dealing with its own property.

                              5.1.3.3 Effort. The Members shall devote such time
to the Company as is  appropriate  to  supervise  and  complete in an  effective
manner the tasks and  activities  assigned to them, but shall not be required to
devote their full time efforts to the Company.

                              5.1.3.4  Means  of  Performance.  Each  Member  is
hereby authorized to take all actions reasonably deemed necessary by it to carry
out its rights and duties under this Agreement.  Subject to the Approved Budget,
and to any additional  limitations  that may be imposed from time to time by the
Executive  Committee,  each  Member may engage  independent  contractors  at the
expense of the Company to assist such Member in performing its duties under this
Agreement and to render services to the Company in connection with the marketing
and sale of the Project.

                  5.1.4 Signature Power of Members.  Either Member, acting alone
and without the joinder of the other Member, shall have the power to execute and
deliver  documents  and  instruments  of every  type and nature on behalf of the
Company,  which shall be binding on the  Company;  provided,  however,  that the
signature  of both  Members  shall be required for  documents  evidencing  Major
Decisions.  Any  Person  dealing  with the  Company  may rely,  without  further
inquiry,  on a  certificate  signed  by  any  Member  as  to  the  existence  or
nonexistence of any fact or facts which constitute a condition precedent to acts
by the Member or which are in any other  manner  germane  to the  affairs of the
Company.  The  Members'  respective  Representatives  shall be their  designated
agents to execute documents on behalf of each such Member and, in addition, each
                                       9
<PAGE>
Member may provide to the other Member from time to time  written  notice of any
other agents designated by the Member to execute documents on its behalf.

         5.2 Approval of Budgets.

                  5.2.1 Types of Budgets. From time to time during the marketing
of the Project,  the Representatives  shall prepare and present for the approval
of the Executive  Committee in accordance with Section 5.3 the following budgets
(each, a "Budget"): (a) a separate, general budget for each phase of the Project
setting  forth in  general  terms  the  budget  needs  for such  phase  over its
anticipated  marketing  term, (b) a separate annual budget for each phase of the
Project  currently being marketed,  setting forth in specific terms and specific
detail all costs expected to be incurred under the relevant  marketing plan, and
(c) a separate annual operating budget for the Company,  setting forth in detail
all anticipated  Company expenses which are not addressed in other more specific
budgets.   Any  Representative  may  from  time  to  time  submit  revisions  or
modifications to Budgets to the Executive Committee for approval;  provided that
no revisions or modifications shall be implemented unless approved in accordance
with Section 5.3 hereof.

                  5.2.2  Annual  Operating  Budgets.  Not  later  than  90  days
following  the  execution  of this  Agreement,  the  Executive  Committee  shall
approve,  in accordance with the provisions of Section 5.3, an initial operating
budget  for the  1998  calendar  year  (the  "Initial  Operating  Budget").  The
Representatives  shall present a revised annual operating budget for approval by
the Executive  Committee  not later than  November 1 of each year  preceding the
year covered by the proposed budget.  The Executive  Committee shall approve the
annual  operating  budget  by  December  1 of each year in  accordance  with the
provisions of Section 5.3.

                  5.2.3  Limitation on  Expenditures;  Use of Reserves.  Budgets
shall  include  a  reasonable   contingency   reserve  for  unanticipated  costs
associated with the matters covered thereby. Specific expenditures to market the
Project  may be made only  pursuant  to an Approved  Budget;  provided  that the
Members  shall have  discretion  to use  contingency  reserves  included  in any
Approved  Budget  in any  reasonable  manner  and  shall  be  permitted  to make
reasonable adjustments between line items reflected on an Approved Budget if the
expenses  intended  to be paid  pursuant  to the line item from which  funds are
transferred  are in fact incurred and paid (at a total cost less than  budgeted)
and the items on which the  transferred  funds are expended were included  among
the items set forth in the Approved  Budget (and were incurred at a cost greater
than budgeted).  Notwithstanding the foregoing, any increase in excess of 25% in
any  individual  line item in an Approved  Budget  that  exceeds  $25,000  shall
require the approval of the Executive Committee.

                  5.2.4 Definitions  Relating to Budgets.  The Initial Operating
Budget and each other Budget, including any revisions thereto, which is approved
in accordance with Section 5.3 hereof, shall be termed an "Approved Budget." All
expense items  identified in the  Company's  Approved  Budgets from time to time
shall constitute "Approved Expenses" of the Company.

         5.3 Mechanism for Obtaining  Consents.  The Representatives may propose
approval of Budgets and amendments  thereto and any marketing plans with respect
to the  Project by the  Executive  Committee  by giving  notice  thereof to each
Representative   (which  notice  may  include  alternative   recommendations  or
proposals by the  Representatives).  The Representatives shall cooperate in good
faith to reach unanimous  agreement on all matters submitted for the approval of
                                       10
<PAGE>
the Executive Committee (including, without limitation, the matters set forth in
Section 5.5 hereof,  any  Budgets,  marketing  plans and  modifications  thereto
proposed  by  a   Representative   and  any  other   matters   proposed  by  the
Representatives)  within 30 days of their submission to the Executive Committee.
If agreement by a unanimous vote of the Representatives  cannot be achieved with
respect to a  particular  issue (the  absence of  agreement  on that issue being
referred to herein as a "Dispute")  within such 30-day period,  the parties wish
to provide for an efficient and prompt  resolution  thereof  through the dispute
resolution   mechanism   of  Section  5.4,   rather  than  through   litigation.
Accordingly,  the Members hereby waive their rights to institute litigation with
respect to any Dispute arising under this  Agreement,  and consent instead to be
bound by the  results  of the  dispute  resolution  mechanism  of  Section  5.4.
Notwithstanding  the foregoing,  disagreements with respect to matters described
in Section 5.5 shall not be "Disputes" nor be subject to resolution  pursuant to
Section 5.4,  provided that a disagreement  regarding whether any act is outside
the scope of the Company's  Permitted  Activities shall constitute a Dispute and
shall be subject to resolution pursuant to Section 5.4.

         5.4 Dispute Resolution.

                  5.4.1 Initial  Designation of  Arbitrators.  The Company shall
maintain  a list of five or more  individuals  whom the  Members  have  mutually
agreed are qualified to serve as  arbitrators to resolve  Disputes.  The initial
arbitrator  list  shall be  agreed  upon by the  Members  and  attached  to this
Agreement not later than January 15, 1998.

                  5.4.2  Disclosure of Business  Relationships;  Replacement  of
Arbitrator.  The Members  shall  disclose to each other in writing all  material
business  relationships they have had in the past five years with any arbitrator
before an arbitrator  is added to the  arbitrator  list.  The Members shall also
disclose  to each other in writing  all  material  business  relationships  they
develop with an arbitrator  once the arbitrator has been added to the arbitrator
list. An  individual  shall remain on the  arbitrator  list until removed by the
mutual  consent of the Members;  provided  that if any Person  designated on the
arbitrator  list  dies,  refuses  to serve or for any other  reason is unable to
serve,  the Members shall designate an additional  Person to fill the vacancy on
the arbitrator  list. An individual  shall be added to the arbitrator  list only
upon the  unanimous  consent of the Members;  provided  that if a vacancy on the
arbitrator  list is not  filled  within 30 days of the event  that  caused  such
vacancy,  the remaining  Persons on the arbitrator  list shall promptly choose a
new arbitrator to fill the vacancy.

                  5.4.3  Dispute  Notice.  If both  Representatives  of a Member
believe that a Dispute exists, the Member shall notify the other Member thereof,
which  notice (a  "Dispute  Notice")  shall  identify  the Dispute and set forth
briefly the notifying Member's position with respect to the Dispute. As promptly
as  practicable,  and in any event  within one week of the giving of the Dispute
Notice,  the  Members  shall meet in an attempt to resolve the  Dispute.  If the
Dispute  cannot be resolved at that  meeting,  either  Member may  institute the
arbitration process on the terms set forth in Section 5.4.4.

                  5.4.4 Arbitration.  The arbitration process shall be conducted
by an arbitrator  selected by random means from the  arbitrator  list  described
above.  In  general,  the  arbitrator  shall  follow  the rules of the  American
Arbitration Association, but shall have discretion to vary from those guidelines
in light of the  nature  or  circumstances  of any  particular  Dispute.  In all
events, 
                                       11
<PAGE>
unless waived by the Members, the arbitrator will conduct an arbitration hearing
at which the Members and their counsel shall be present and have the opportunity
to present evidence and examine the evidence  presented by the other Member. The
proceedings at the arbitration  hearing shall,  unless waived by the Members, be
conducted  under oath and before a court  reporter.  Upon the  conclusion of the
arbitration  hearing,  the arbitrator shall and must select the position offered
by one of the Members with respect to each individual  Dispute (i.e., each issue
presented for  resolution),  without  variation.  The parties shall cooperate in
good faith to permit a  conclusion  of the  arbitration  hearing  within 90 days
following the meeting described in Section 5.4.3, and shall endeavor to submit a
joint statement  setting forth each Dispute to be resolved,  including a summary
of each Member's  position on each Dispute.  The decision of the arbitrator with
respect to any  Dispute  shall be final and  binding on the Members and shall be
treated as an  approval  of the matter  subject  to the  Dispute by the  Members
pursuant to Section 5.3.

                  5.4.5  Standards  of  Conduct.  The  Members  agree  that with
respect to all aspects of the dispute  resolution  process contained herein they
will  conduct  themselves  in a manner  intended  to assure  the  integrity  and
fairness of that process. To that end, if a Dispute is submitted to arbitration,
the Members agree that they will not contact or communicate  with the arbitrator
with  respect to any  Dispute  either ex parte or outside  of the  contacts  and
communications  contemplated  by this Section 5.4, and the Members further agree
that they will  cooperate in good faith in the  production  of  documentary  and
testimonial  evidence in a prompt and efficient  manner to permit the review and
evaluation thereof by the other Member.

                  5.4.6 Costs.  The cost of resolving any Dispute by arbitration
shall be borne by the Company  (and shall be treated as an Approved  Expense for
all purposes of this Agreement).

         5.5 Major Decisions. Notwithstanding any provision of this Agreement to
the contrary, the following matters (each, a "Major Decision") shall require the
consent  of both  Members,  which  may be  withheld  in the  sole  and  absolute
discretion of each Member (and which shall not be subject to resolution pursuant
to Section 5.4 hereof):

                  5.5.1 Any amendment to this Agreement;

                  5.5.2  An act  which is  outside  the  scope of the  Company's
Permitted Activities;

                  5.5.3 The  dissolution of the Company  pursuant to Section 9.1
hereof;

                  5.5.4 Admission of any new Member to the Company;

                  5.5.5 Filing, consenting to or acquiescing in any act or event
that would constitute an event of bankruptcy with respect to the Company;

                  5.5.6  Acquiring by lease,  purchase or  otherwise  additional
real property;

                  5.5.7 Any call for Additional Capital  Contributions in excess
of the aggregate cap on Additional  Capital  Contributions  set forth in Section
2.4;
                                       12
<PAGE>
                  5.5.8  Incurring  any  material  cost or  expense  that is not
authorized  in  an  Approved   Budget  or  undertaking   any  activity  that  is
inconsistent with any approved marketing plan;

                  5.5.9  Determining  the amount of reserves to be maintained by
the Company;

                  5.5.10 Borrowing or incurring an obligation for borrowed funds
in any amount, unless such borrowing is specifically contemplated in an Approved
Budget or is accomplished  pursuant to a Default Loan as provided in Section 2.6
hereof;

                  5.5.11  Entering into or making bulk sales or long term leases
of substantial portions of the Property; or

                  5.5.12  Entering  into  any  contract  or  arrangement   which
requires  any  payments  to any  Affiliate  of a  Member,  except  as  expressly
authorized by this Agreement.

 . The  provisions of this Section 5.6 are intended to serve as guidelines to the
Executive  Committee in attempting to agree on any approved  marketing plan, and
the Approved  Budgets and other matters  contemplated  by this Agreement (and to
serve as a basis or standard to be applied by an arbitrator  pursuant to Section
5.4 hereof, if necessary).

                  5.6.1 Agreement to Optimize  Returns.  It is the intent of the
Company  to  market  the  Project  as soon as  market  and  other  circumstances
reasonably  permit.  Any  marketing  plan shall be  prepared  in a manner  which
optimizes  the  Members'   returns  from  the  Project  over  its   contemplated
development  cycle,  consistent  with good  land  planning  principles,  prudent
business practices and market conditions.

                  5.6.2   Consideration  of  Parties'  Varying  Interests.   Any
marketing  plan and each Budget shall take into  consideration  all of the facts
relating to the Members and the  Property,  including  the  Members'  respective
capital  investments  and  interests  in  the  Company,   the  economic  sharing
arrangements  contemplated by this Agreement and the need for marketing and sale
of the Property in an orderly manner that protects the interests of all Members.
                                       13

         5.7 Limitations on Liability; Indemnity. No Member, its Representatives
or its or their  Affiliates  (an "Actor")  shall be liable to the Company or the
other Members for actions  taken in good faith by the Actor in  connection  with
the Company or its  business;  provided  that the Actor  shall in all  instances
remain  liable  for acts in breach of this  Agreement  or which  constitute  bad
faith,  fraud,  willful misconduct or gross negligence (except to the extent the
Company  is  compensated  for  the  same by  insurance  coverage  maintained  in
accordance  with this  Agreement).  The Company,  its receiver or trustee  shall
indemnify,  defend and hold harmless each Actor,  to the extent of the Company's
assets  (without  any  obligation  of any  Member to make  contributions  to the
Company to fulfill  such  indemnity),  from and against any  liability,  damage,
cost, expense,  loss, claim or judgment incurred by the Actor arising out of any
claim  based upon acts  performed  or omitted  to be  performed  by the Actor in
connection  with the  business  of the  Company,  including  without  limitation
attorneys'  fees and costs incurred by the Actor in the settlement or defense of
such claim;  provided that no Actor shall be  indemnified  for claims based upon
acts  performed or omitted in breach of this  Agreement or which  constitute bad
faith, fraud, willful misconduct or gross negligence.

         5.8  Compensation  and  Expenses of the Members.  The Members  shall be
entitled to reimbursement  from the Company for costs incurred by them and their
Representatives  in connection with the performance of their  respective  duties
hereunder  in the  manner  and  to the  extent  set  forth  on  Exhibit  A.  The
reimbursements  set forth on Exhibit A are  intended  to fully  compensate  each
Member for any direct  expenses  incurred by the Members or the  Representatives
for legal,  accounting,  auditing and other services provided for the benefit of
the Company  (whether  rendered by Affiliates of a Member or  Representative  or
otherwise) and for any facilities  (such as office space) and supplies  provided
to the  Company  and,  except  as set forth on  Exhibit  A, the  Members,  their
Affiliates and their Representatives shall not receive any reimbursement for the
foregoing  items  or  matters,   nor  shall  they  receive  any  fees  or  other
compensation from the Company,  unless  unanimously  agreed from time to time by
the Members.

         SECTION 6. BOOKS AND RECORDS

         6.1 Books and Records. UDC shall keep adequate books and records at the
Company's  place of business,  setting forth a true and accurate  account of all
business  transactions  arising out of and in connection with the conduct of the
Company.  The costs and expenses  (including  employee costs) incurred by UDC in
maintaining  such books and  records  shall be paid or  reimbursed  to it by the
Company to the extent  provided  in Section  5.8.  Any Member or its  designated
representative  shall have the right, at any reasonable  time, to have access to
and inspect,  copy and audit the  contents of such books or records.  Unless the
Executive  Committee  determines  otherwise,  the Company's  financial books and
records  shall be audited  annually at the expense of the Company,  by a firm of
independent certified  accountants selected by the Executive Committee,  and the
costs of the audit shall be treated as an Approved  Expense for purposes of this
Agreement.

         6.2 Reports. Within 45 days following the end of each calendar quarter,
UDC  shall  furnish  each  Member  with:  (a) cash  basis  financial  statements
consisting of a balance  sheet and income  statement for the quarter then ended,
and,  in the case of the  report for the last  quarter  of each  year,  the same
financial statements for the year then ended; and (b) a marketing status report.
UDC shall also  provide  monthly  statements  to the  Members  comparing  actual
Company expenses with those projected on the then current Approved Budget.
                                       14
<PAGE>
         6.3 Tax  Matters.  UDC shall  cause  necessary  tax  information  to be
delivered to each Member as soon as reasonably practicable after the end of each

tax information and tax returns relating to the Company, subject to the approval
of the Executive Committee.

         6.4 Bank  Accounts.  UDC shall open and maintain in the Company's  name
one or more bank  accounts,  into which shall be deposited all Company funds and
only Company  funds.  The funds in the Company's  bank accounts may be withdrawn

be made by checks or other withdrawal forms signed by UDC.

         SECTION 7. AMENDMENTS

         7.1 Amendments.  This Agreement may not be amended, except by a written
instrument signed by the Members.

         SECTION 8. TRANSFER OF COMPANY INTERESTS; NEW MEMBERS

         8.1  General.  No  Member  shall  sell,  assign,  pledge,  hypothecate,
encumber or otherwise  voluntarily  transfer by any means whatever  ("Transfer")
all or any portion of its interest in the Company (or permit any Person directly
or  indirectly  holding any interest in such Member  directly or  indirectly  to
Transfer  any part of such  interest),  except for  Transfers  (a)  approved  in
writing by all Members,  or (b) permitted under Section 8.2 hereof. A transferee
of a Member's  interest in the Company will be admitted as a Substituted  Member
only  pursuant to Section  8.4 hereof.  Any  purported  Transfer  which does not
comply with the  provisions  of this  Section 8 shall be void and of no force or
effect.

         8.2 Permitted Transfers.  Notwithstanding  Section 8.1 hereof, a Member
may permit direct and indirect  Transfers of interests in such Member so long as
such Transfers do not result in a Change in Control of such Member.

         8.3  Assignee of Member's  Interest.  If,  pursuant to a Transfer of an
interest in the Company by operation of law and without violation of Section 8.1
hereof (or  pursuant to a Transfer  that the  Company is  required to  recognize
notwithstanding any contrary provisions of this Agreement), a Person acquires an
interest in the Company, but is not admitted as a Substituted Member pursuant to
Section 8.4 hereof, then, subject to Section 8.5 hereof, such Person:

                  8.3.1 shall be treated as an assignee of a Member's  interest,
as provided in the Act;

                  8.3.2 shall have no right to  participate  in the business and
affairs  of the  Company  or to  exercise  any  rights  of a Member  under  this
Agreement or the Act; and

                  8.3.3  shall  share in  distributions  from the  Company  with
respect  to the  transferred  interest,  on the same  basis as the  transferring
Member.
                                       15
<PAGE>
         8.4  Substituted  Members.  No Person taking or acquiring,  by whatever
means,  the  interest  of any  Member  in the  Company  shall be  admitted  as a
substituted  Member in the Company (a "Substituted  Member") without the written
consent of all Members, which consent may be withheld or granted in the sole and
absolute discretion of each Member.

         8.5 Option to Purchase.

                  8.5.1 General. Upon any Transfer of an interest in the Company
in  violation  of this  Section 8 or upon a Transfer of any interest in a Member
that is prohibited by this Agreement (a "Triggering  Event"), the Member to whom
a Triggering  Event has not occurred (the "Option Member") shall have the right,
but not the  obligation,  to purchase  the entire  interest in the Company  (the
"Option  Interest")  of the Member to whom the  Triggering  Event  occurred (the
"Selling Member"), on the terms and conditions set forth in this Section 8.5.

                  8.5.2  Election.  An Option  Member may  invoke the  valuation
procedure of Section 8.5.3 by giving written notice (the "Valuation  Notice") to
the Selling  Member (or, if  applicable,  its  representatives,  successors,  or
assigns) and to each other Option Member,  if any, at any time within six months
following the Option Member's actual knowledge of the Triggering Event.

                  8.5.3 Valuation  Procedure.  For a period of 60 days following
the  Valuation  Notice,  the  Option  Member  and the  Selling  Member  (or,  if
applicable,  the  representatives,  successors or assigns of the Selling Member)
shall  negotiate in good faith to determine  the fair market value of all of the
Company's  assets,  taken  as a  whole,  exclusive  of  any  goodwill  or  other
intangible  asset that does not have a book value for  accounting  purposes (the
"Assets").  If the parties  are unable to agree on the fair market  value of the
Assets within the prescribed  60-day period,  the parties shall,  within 15 days
following  the end of such 60-day  period,  unanimously  select an  appraiser or
appraisers to determine the fair market value of the Assets.  If the parties are
unable to agree on an  appraiser  or  appraisers  within  the  foregoing  15-day
period,  then at the  election of any party,  the  selection  of an appraiser or
appraisers  shall be submitted to dispute  resolution in accordance with Section
5.4 hereof.  Following his or their selection,  the appraiser(s) shall determine
as soon as  practicable  the fair  market  value  of the  Assets  assuming,  for
purposes of determining such value, that the Assets are liquidated in an orderly
manner over a period of six months.  The parties'  agreement as to value,  or if
applicable,  the  appraiser's  (appraisers')  determination  of  value  shall be
binding on all parties for purposes of this Agreement.  The date of the parties'
agreement on the value of the Assets,  or, if applicable,  the date of the final
appraisal  report(s),  is referred to hereinafter  as the "Valuation  Date." All
appraisal  costs  and costs  under  Section  5.4  shall be borne by the  Selling

                  8.5.5  Exercise  of  Right.   Within  60  days  following  the
Valuation  Date,  the Option  Member  shall give  written  notice to the Selling
Member  stating  whether  such  Option  Member  desires to  purchase  the Option
Interest.  The Option Member shall thereafter be entitled to purchase the Option
Interest  by  delivering  to the  Selling  Member  (or,  if  applicable,  to the
representatives,  successors  or  assigns  of the  Selling  Member)  the  Option
Member's negotiable  promissory note (the "Note") in a principal amount equal to
the purchase  price  determined  under  Section  8.5.4,  payable in equal annual
installments of principal together with annual payments of interest at the Prime
Rate, over a period not to exceed five years, with the first installment due and
payable  one  year  from  the date of sale.  The  Note  shall  be  secured  by a
collateral assignment of the Option Interest acquired by the Option Member, in a
commercially  reasonable form determined by the Option Member. The Note shall be
due and  payable  in full at such  time  as the net  fair  market  value  of the
Company's  remaining  assets (as reasonably  determined by the Option Member) is
less than 200% of the then outstanding balance of the Note.

                  8.5.6 Deliveries by Selling Member.  Upon receipt of an Option
Member's  Note,  the Selling  Member (or, if  applicable,  its  representatives,
successors or assigns) shall deliver to the Option Member an executed assignment
of the Option Interest to be acquired by the Option Member, sufficient to convey
such  interest to the Option  Member free and clear of any  liabilities,  liens,
claims or encumbrances,  except those taken subject to by the Option Member,  as
provided below.

                  8.5.7 Assumption and Release.  In connection with the purchase
of any portion of the Option Interest hereunder, the Option Member shall release
the  Selling  Member  from and  assume,  as  appropriate,  such  Company-related
obligations  and  guarantees as shall relate to the  transferred  portion of the
Option Interest and agree to indemnify and hold harmless the Selling Member with
respect to all such obligations and guarantees.

                  8.5.8 Closing  Adjustments.  If the Option Interest is subject
to any liability, lien, claim or encumbrance (including, without limitation, any
Default Loan), the Option Member may elect (a) to cause the purchase price (or a
portion  thereof) to be applied to  discharge  such  liability,  lien,  claim or
encumbrance,  or (b) to take the relevant portion of the Option Interest subject
to such liability,  lien,  claim or encumbrance and to reduce the purchase price
otherwise  payable by the Option  Member to the Selling  Member by the amount of
such liability, lien, claim or encumbrance.

                  8.5.9 Use of Nominee.  At the election of a Option Member, the
purchase of all or part of the Option Interest  pursuant to this Section 8.5 may
be completed by a nominee of the Option Member,  in which case, the  obligations
of the Option  Member  under this  Section 8.5 shall be performed by the nominee
rather than the Option Member.

         8.6 Distributions in Respect of Transferred Interests.  If any interest
in the Company is transferred  during any accounting  period in compliance  with
the  provisions  of this Section 8, all  distributions  on or before the date of
such Transfer shall be made to the transferor,  and all distributions thereafter
shall be made to the transferee.
