     Inventory Lots:               Six Hundred Twenty-Five (625).

     Borrower may increase the number of Specs  allowed above by the same number

     agrees not to allow,  and is prohibited  from  allowing,  any more than ten
     (10) Specs,  three (3) Models or one hundred fifty (150)  Inventory Lots to

AGREEMENT")  dated  as of the date  hereof  amending  certain  other  terms  and
provisions of the Loan  Instruments.  (Hereafter,  this Agreement and the Letter
Agreement shall be included in the defined term "LOAN INSTRUMENTS.")

     4. Borrower  acknowledges and agrees, that as an accommodation to Borrower,
Exhibit A hereto  (which  exhibit  describes the  recording  information  of the
Master Deeds of Trust) shall be attached to this  Agreement  (and to any and all

     now or hereafter  executed by Borrower (or any future owner of the Property
     if different from Borrower) and duly recorded in the  appropriate  official
     public  records,  Borrower  acknowledges  and agrees that such amendment or
     modification of the Master Deeds of Trust shall  constitute an amendment or
     modification to the terms and provisions of any such Supplemental  Deeds of
     Trust (and shall be incorporated into any such Supplemental  Deeds of Trust
     and made a part  thereof  for all  purposes,  as though such  amendment  or
     modification  of the Master  Deeds of Trust  specifically  referred to such
     Supplemental  Deeds  of  Trust)  without  the  necessity  of  any  specific
     reference in such amendment or modification to any such Supplemental  Deeds
     of Trust;  and no such  amendment  or  modification  of the Master Deeds of
     Trust shall impair the obligations of Borrower under any such  Supplemental
     Deeds of Trust or any other of the Loan Instruments.

     6. Borrower hereby  expressly  promises to pay to the order of Lender,  the
principal  amount of the Note (as  modified and  increased)  and all accrued and
unpaid  interest now or hereafter to become due and payable under the Note,  and
Borrower hereby expressly promises to perform all of the obligations of Borrower
under the Loan Instruments (as modified and increased).

     7. The liens of the Deeds of Trust are hereby  acknowledged  by Borrower to
be good,  valid and  subsisting  liens,  and such liens are hereby  renewed  and
extended  so as to secure  the  payment  of the Note and Loan (as  modified  and
increased).

     8. Borrower  hereby  represents and warrants to Lender that (a) Borrower is
the sole legal and beneficial  owner of the Property;  (b) Borrower has the full
power and authority to make the agreements  contained in this Agreement  without
joinder or consent of any other party; (c) the

execution,  delivery and  performance  of this  Agreement will not contravene or
constitute  an event which itself or which with the passing of time or giving of
notice  or both  would  constitute  a  default  under  any deed of  trust,  loan
agreement,  indenture  or other  agreement  to which  Borrower or Guarantor is a
party or by which Borrower or any of its property is bound; and (d) there exists
no default under the Loan  Instruments (as modified).  BORROWER HEREBY AGREES TO
INDEMNIFY AND HOLD LENDER HARMLESS AGAINST ANY LOSS, CLAIM, DAMAGE, LIABILITY OR
EXPENSE (INCLUDING WITHOUT LIMITATION,  ATTORNEYS' FEES) INCURRED AS A RESULT OF
ANY  REPRESENTATION  OR WARRANTY MADE BY BORROWER HEREIN PROVING TO BE UNTRUE IN
ANY MATERIAL RESPECT.

     9. The terms and conditions hereof may not be modified, amended, altered or
otherwise  affected  except by  instrument  in  writing  executed  by Lender and
Borrower.

     10.  All Loan  Instruments  are hereby  amended  and  modified  in a manner
consistent with the  modifications,  terms and/or  provisions  contained herein.
Except as  expressly  modified  hereby,  the terms  and  conditions  of the Loan
Instruments are and shall remain in full force and effect.

     11. Borrower agrees to pay to Lender,  contemporaneously with the execution
and delivery  hereof,  all costs and expenses  incurred in connection  with this
transaction,  title insurance endorsement premiums,  reasonable fees of Lender's
counsel and recording fees.

     12.  Borrower  hereby  agrees to execute and deliver to Lender such further
documents and instruments  evidencing or pertaining to the Loan, as modified and
increased hereby, as may be reasonably  requested by Lender from time to time so
as to evidence the terms and conditions hereof.

                      SPECIAL TAX AND ACCOUNTING PROVISIONS


     A.1  ACCOUNTING   DEFINITIONS.   The  following   terms,   which  are  used
predominantly  in this  Appendix A, shall have the  meanings set forth below for
all purposes under this Agreement:

the  balance of such  Partner's  Capital  Account as of the end of the  relevant
Fiscal Year, after giving effect to the following adjustments:

          (a) Credit to such Capital  Account any amounts  which such Partner is
obligated to restore  pursuant to this  Agreement or as  determined  pursuant to
Regulations  Section  1.704-1(b)(2)(ii)(Q),  or is  deemed  to be  obligated  to

          (b) Debit to such Capital  Account the items described in clauses (4),
(5) and (6) of Section 1.704-1(b)(2)(ii)(d) of the Regulations.

The foregoing  definition  of Adjusted  Capital  Account  Balance is intended to
comply with the provisions of Section  1.704-1(b)(2)(ii)(d)  of the  Regulations
and shall be interpreted consistently therewith.

          "BOOK VALUE" means,  with respect to any asset,  the asset's  adjusted
basis for federal income tax purposes, except as follows:

          (a)  The  initial   Book  Value  for  any  asset  (other  than  money)
contributed by a Partner to the  Partnership  shall be the value as set forth in
this Agreement or, if not set forth in this Agreement,  as reasonably determined
by the General Partner;

          (b) The Book Value of all  Partnership  assets  shall be  adjusted  to
equal their respective gross fair market values, as reasonably determined by the
General  Partner as of the following  times:  (i) the  acquisition of additional
Units in the  Partnership  by any new or existing  Partner in exchange  for more
than a de minimis Capital Contribution; (ii) the distribution by the Partnership
to a  Partner  of  more  than  a de  minimis  amount  of  cash  or  property  as
consideration  for  Units  in  the  Partnership,  if (m  any  such  event)  such
adjustment  is  necessary  or  appropriate,  in the  reasonable  judgment of the
General Partner,  to reflect the relative economic  interests of the Partners in
the Partnership;  or (iii) the liquidation of the Partnership for federal income
tax purposes pursuant to Regulations Section 1.704-1(b)(2)(ii)(g);

          (c) The Book Value of any Partnership asset distributed to any Partner
shall  be  adjusted  to  equal  its  gross  fair  market  value  on the  date of
distribution, as reasonably determined by the General Partner;

          (d) The Book Values of the Partnership's assets shall be increased (or
decreased)  to reflect  any  adjustments  to the  adjusted  basis of such assets
pursuant to Code Section 734(b) or Code Section  743(b),  but only to the extent
that such  adjustments  are taken into account in determining  Capital  Accounts
pursuant to Regulation Section  1.704-1(b)(2)(iv)(m)  and Section A.2(g) hereof;
provided,  however,  that Book  Values  shall not be  adjusted  pursuant to this
subsection  (d) to the extent that an adjustment  pursuant to subsection  (b) of
this  definition is necessary or  appropriate  in connection  with a transaction
that would  otherwise  result in an adjustment  pursuant to this subsection (d);
and

          (e) If the Book  Value of an asset  has been  determined  or  adjusted
pursuant to subsection (a), (b) or (d) above,  such Book Value shall  thereafter
be  adjusted  by the  Depreciation  taken  into  account  from time to time with
respect to such asset for purposes of computing Profits and Losses.

          "CAPITAL ACCOUNT" means, with respect to any Partner or other owner of
Units in the  Partnership,  the Capital  Account  maintained  for such Person in
accordance with the following provisions:

          (a) To each such Person's Capital Account, there shall be credited the
amount of cash  contributed  to the capital of the  Partnership  and the initial
Book Value of any noncash assets  contributed to the capital of the  Partnership
by such Person, such Person's distributive share of Profits and any items in the
nature of income or gain that are specially  allocated  pursuant to Sections A.2
and A.3 hereof,  and the amount of any Partnership  liabilities  assumed by such
person  (excluding  assumed  liabilities  that have been taken  into  account in
computing  the  Book  Value  of any  Partnership  property  distributed  to such
Person);

          (b) To each such Person's  Capital  Account there shall be debited the
amount of cash and the Book Value of any  Partnership  property  distributed  to
such  Person  pursuant  to  any  provision  of  this  Agreement,  such  person's
distributive  share of Losses, and any items in the nature of expenses or losses
that are specially  allocated  pursuant to Sections A.2 and A.3 hereof,  and the
amount of any liabilities of such Person assumed by the Partnership;

          (c) In the event  any  Units in the  Partnership  are  transferred  in
accordance with the terms of this.  Agreement,  the transferee  shall succeed to
the  Capital  Account  of  the  transferor  to  the  extent  it  relates  to the
transferred interest;

          (d)  Section  752(c) of the Code shall be applied in  determining  the
amount of any liabilities  taken into account for purposes of this definition of
"Capital Account"; and

                                       -2-

          (e)  The  foregoing  provisions  and  the  other  provisions  of  this
Agreement relating to the maintenance of Capital Accounts are intended to COMPLY
with Sections 1.704-1(b) and 1.704-2 of the Regulations and shall be interpreted
and applied in a manner  consistent with such  Regulations.  The General Partner
may modify the manner of computing the Capital Accounts or any debits or credits
thereto (including debits or credits relating to liabilities that are secured by
contributed  or distributed  property or that are assumed by the  Partnership or
any Partner) in order to comply with such  Regulations,  provided  that any such
modification   is  not  likely  to  have  a  material   effect  on  the  amounts
distributable  to any Partner upon the dissolution of the  Partnership.  Without
limiting the  generality of the preceding  sentence,  the General  Partner shall
make any  adjustments  that are necessary or  appropriate  to maintain  equality
between  the  aggregate  sum of the Capital  Accounts  and the amount of capital
reflected  on the  balance  sheet of the  Partnership,  as  determined  for book
purposes in accordance with Section 1.704-1(b)(2)(iv)(g) of the Regulations. The
General Partner shall also make any appropriate  modifications  if unanticipated
events (for example, the availability of investment tax credits) might otherwise
cause this Agreement not to comply with Regulations Section 1.704-1(b).

          "PARTNERSHIP   MINIMUM   GAIN"  has  the  same  meaning  as  the  term
"partnership   minimum  gain"  under  Regulations   Section  1.704-2(d)  of  the
Regulations.

          "DEPRECIATION"  means, for each Fiscal Year or other period, an amount
equal  to the  depreciation,  amortization  or  other  cost  recovery  deduction
allowable with respect to an asset for such year or other period, except that if
the Book Value of an asset  differs from its adjusted  basis for federal  income
tax purposes at the beginning of such year or other period,  Depreciation  shall
be an amount  that  bears the same  ratio to such  beginning  Book  Value as the
federal income tax depreciation,  amortization or other cost recovery  deduction
for such  year or other  period  bears to such  beginning  adjusted  tax  basis;
provided,  however,  that if  such  depreciation,  amortization  or  other  cost
recovery  deductions  with  respect  to any such  asset for  federal  income tax
purposes is zero for any Fiscal  Year,  Depreciation  shall be  determined  with
reference  to the  asset's  BOOK Value at the  beginning  of such year using any
reasonable method selected by the General Partner.

          "PARTNER  NONRECOURSE  DEBT" has the same meaning as the term "partner
nonrecourse debt" under Section 1.704-2(b)(4) of the Regulations.

          "PARTNER  NONRECOURSE  DEBT MINIMUM  GAIN" has the same meaning as the
term "partner nonrecourse debt minimum gain" under Section  1.704-2(i)(2) of the
Regulations and shall be determined in accordance with Section  1.704-2(i)(3) of
the Regulations.

          "PARTNER  NONRECOURSE  DEDUCTIONS"  has the same  meaning  as the term
"partner nonrecourse  deductions" under Regulations Section  1.704-2(i)(1).  The
amount of Partner  Nonrecourse  Deductions with respect to a Partner Nonrecourse
Debt for each Fiscal Year of the  Partnership  equals the excess (if any) of the
net  increase  (if any) in the amount of Partner  Nonrecourse  Debt Minimum Gain
attributable to such Partner  Nonrecourse  Debt during such Fiscal Year over the
aggregate  amount  of  any  distributions during such Fiscal Year to the Partner

                                       -3-

that bears the economic  risk of loss for such Partner  Nonrecourse  Debt to the
extent that such distributions are from the proceeds of such Partner Nonrecourse
Debt which are allocable to an increase in Partner Nonrecourse Debt Minimum Gain
attributable  to such Partner  Nonrecourse  Debt,  determined in accordance with
Section 1.704-2(i)(2) of the Regulations.

          "NONRECOURSE DEBT" or "NONRECOURSE  LIABILITY" has the same meaning as
the term "nonrecourse liability" under Section 1.704-2(b)(3) of the Regulations.

          "NONRECOURSE   DEDUCTIONS"  has  the  meaning  set  forth  in  Section
1.704-2(b)(1)  of the  Regulations.  The amount of Nonrecourse  Deductions for a
Partnership  Fiscal Year equals the excess (if any) of the net increase (if any)
in the amount of  Partnership  Minimum  Gain  during  that  Fiscal Year over the
aggregate amount of any  distributions  during that Fiscal Year of proceeds of a
Nonrecourse Debt that are allocable to an increase in Partnership  Minimum Gain,
determined according to the provisions of Section 1.704-2(c) of the Regulations.

          "PROFITS" or "LOSSES" means, for each Fiscal Year or other period, the
taxable  income or taxable  loss of the  Partnership  as  determined  under Code
Section  703(x)  (including in such taxable  income or taxable loss all items of
income,  gain, loss or deduction  required to be stated  separately  pursuant to
Section 703(a)(1) of the Code) with the following adjustments:

          (a) All items of gain or loss  resulting  from any  disposition of the
Partnership's  property shall be determined  upon the basis of the Book Value of
such property rather than the adjusted tax basis thereof;

          (b) Any income of the  Partnership  that is exempt from federal income
tax shall be added to such taxable income or loss;

          (c) Any  expenditures  of the  Partnership  that are described in Code
Section  705(a)(2)(B),  or  treated  as such  pursuant  to  Regulations  Section
1.704-1(b)(2)(iv)(j),  and that are not  otherwise  taken  into  account  in the
computation of taxable income or loss of the  Partnership,  shall be deducted in
the determination of Profits or Losses;

          (d) If the Book Value of any Partnership asset is adjusted pursuant to
subsection  (b) or (c) of the  definition  of "Book  Value"-  set  forth in this
Appendix A, the amount of such adjustment shall be taken into account as gain or
loss from the  disposition  of such asset for purposes of  computing  Profits or
Losses unless such gain or loss is specially  allocated  pursuant to Section A.2
hereof;

          (e) In lieu of the depreciation, amortization, and other cost recovery
deductions  taken into account in determining such taxable income or loss, there
shall be deducted  Depreciation,  computed in accordance  with the definition of
such term in this Appendix A; and

                                       -4-

          (f)  Notwithstanding any of the foregoing  provisions,  any items that
are specially allocated pursuant to Section A.2 or A.3 hereof shall not be taken
into account in computing Profits or Losses.

     A.2  SPECIAL  ALLOCATIONS.  The  allocation  of Profits and Losses for each
Fiscal Year shall be subject to the following  special  allocations in the order
set forth below:

          (a) Section  704(c) In  accordance  with Code  Section  704(c) and the
Regulations  thereunder,  income,  gain,  loss and deduction with respect to any
in-kind property  contributed to the capital of the Partnership,  shall,  solely
for tax purposes,  be allocated  among the Partners so as to take account of any
variation  between the adjusted  basis of such property to the  Partnership  for
federal  income tax purposes  and its initial Book Value.  In the event the Book
Value of any  Partnership  asset is adjusted  pursuant to subsection  (b) of the
definition  of "Book  Value" in Section  A.1 of  Appendix  A to this  Agreement,
subsequent  allocations of income, gain, loss and deduction with respect to such
asset shall take account of any  variation  between the  adjusted  basis of such
asset for federal  income tax  purposes and its Book Value in the same manner as
under Code Section 704(c) and the Regulations thereunder. Any elections or other
decisions relating to such allocations shall be made by the General Partner.  in
any manner that reasonably reflects the purpose and intention of this Agreement.
Allocations  pursuant to this Section are solely for purposes of federal,  state
and local  taxes and shall not  affect,  or in any way be taken into  account in
computing,  any person's  Capital  Account or share of Profits,  Losses or other
items or distributions pursuant to any provision of this Agreement.

          (b) Partner  Minimum  Gain  Chargeback.  If there is a net decrease in
Partnership  Minimum Gain for any Fiscal Year,  each Partner  shall be specially
allocated  items of  income  and gain for such  year  (and,  if  necessary,  for
subsequent years) in an amount equal to such Partner's share of the net decrease
in  Partnership  Minimum Gain during such year,  determined in  accordance  with
Regulations  Section  1.704-2(g)(2).   Allocations  pursuant  to  the  preceding
sentence  shall be made  among the  Partners  in  proportion  to the  respective
amounts  required to be allocated to each of them  pursuant to such  Regulation.
The items to be so allocated shall be determined in accordance with  Regulations
Section 1.704-2(f)(6). Any special allocation of items of Partnership income and
gain pursuant to this Section  A.2(a) shall be made before any other  allocation
of items under this  Appendix A. This Section  A.2(a) is intended to comply with
the "minimum gain chargeback"  requirement in Regulations Section 1.704-2(f) and
shall be interpreted consistently therewith.

          (c) Partner  Nonrecourse Debt. Minimum Gain Chargeback.  If there is a
net decrease during a Fiscal Year in the Partner  Nonrecourse  Debt Minimum Gain
attributable  to a Partner  Nonrecourse  Debt, then each Partner with a share of
the Partner Nonrecourse Debt Minimum Gain attributable to such debt,  determined
in  accordance  with  Regulations  Section  1.704-2(i)(5),  shall  be  specially
allocated items of income and gain for such year (and, if necessary,  subsequent
years)  an  amount  equal to such  Partner's  share of the net  decrease  in the
Partner  Nonrecourse Debt Minimum Gain attributable to such Partner  Nonrecourse
Debt,   determined  in  accordance  with  Regulations   Section   1.704-2(i)(4).

                                       -5-

Allocations  pursuant to the preceding sentence shall be made among the Partners
in proportion to the respective amounts to be allocated to each of them pursuant
to such Regulation.  Any special allocation of items of income and gain pursuant
to this  Section  A.2(b)  for a Fiscal  Year  shall  be made  before  any  other
allocation of  Partnership  items under this Appendix A, except only for special
allocations  required under Section A.2(a) hereof.  The items to be so allocated
shall be determined in accordance with Regulations Section  1.704-2(i)(4).  This
Section A.2(b) is intended to comply with the provisions of Regulations  Section
1.704-2(i)(4) and shall be interpreted consistently therewith.

          (d)  QUALIFIED  INCOME  OFFSET.  If any Partner other than the General
Partner receives any  adjustments,  allocations,  or distributions  described in
clauses (4), (5) or (6) of Regulations  Section  1.704-1(b)(2)(ii)(d),  items of
income and gain shall be  specially  allocated to each such Partner in an amount
and  manner  sufficient  to  eliminate  as quickly  as  possible,  to the extent
required by such  Regulation,  any deficit in such  Partner's  Adjusted  Capital
Account  Balance,  such  balance to be  determined  after all other  allocations
provided for under this Appendix A have been tentatively made as if this Section
A.2(d) were not in this Agreement.

          (e) GROSS INCOME  ALLOCATION.  In the event any Partner  other' than a
General  Partner  has a deficit  Capital  Account at the end of any Fiscal  Year
which is in  excess  of the sum of (i) the  amount  (if  any)  such  Partner  is
obligated to restore  pursuant to any provision of this Agreement,  and (ii) the
amount  such  Partner  is deemed to be  obligated  to  restore  pursuant  to the
penultimate  sentences  of  Sections  1.704-2(g)(1)  and  1.704-2(i)(5)  of  the
Regulations,  each such Partner shall be specially allocated items of income and
gain in the  amount of such  excess as  quickly as  possible,  provided  that an
allocation  pursuant  to this  Section  A.2(e)  shall be made only if and to the
extent that such Partner would have a deficit  Capital Account in excess of such
sum after all other  allocations  provided for in this Appendix A have been made
as if Section A.2(d) hereof and this Section A.2(e) were not in this Agreement.

          (t) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for any Fiscal Year
or other period shall be specially  allocated to the Partners in  proportion  to
their Percentage Units.

          (g) PARTNER NONRECOURSE DEDUCTIONS. Partner Nonrecourse Deductions for
any Fiscal Year or other period shall be specially allocated, in accordance with
Regulations  Section  1.704-2(i)(1),  to the  Partner or  Partners  who bear the
economic risk of loss for the Partner  Nonrecourse Debt to which such deductions
are attributable.

          (h) CODE SECTION 754  ADJUSTMENTS.  To the extent an adjustment to the
adjusted tax basis of any.Partnership  asset under Code Section 734(b) or 743(b)
is required to be taken into account in determining Capital Accounts pursuant to
Regulations Section  1.704-1(b)(2)(iv)(m),  the amount of such adjustment to the
Capital  Accounts  shall  be  treated  as an  item of  gain  (if the  adjustment
increases  the basis of the  asset) or loss (if the  adjustment  decreases  such
basis), and such gain or loss shall be specially  allocated to the Partners in a
manner  consistent with the manner in which their Capital  Accounts are required
to be adjusted pursuant to such section of the Regulations.

                                       -6-

     A.3 CURATIVE  ALLOCATIONS.  The  allocations  set forth in subsections  (b)
through (h) of Section A.2 hereof  ("Regulatory  Allocations")  are  intended to
comply with certain requirements of Regulations Sections 1.704-1(b) and 1.704-2.
Notwithstanding  any  other  provisions  of this  Appendix  A  (other  than  the
Regulatory  Allocations  and the next two following  sentences),  the Regulatory
Allocations shall be taken into account in allocating other Profits,  Losses and
items of income,  gain,  loss and  deduction  among the Partners so that, to the
extent possible, the net amount of such allocations of other Profits, Losses and
other items and the Regulatory Allocations to each Partner shall be equal to the
net amount that would have been allocated to each such Partner if the Regulatory
Allocations had not occurred.  For purposes of applying the preceding  sentence,
Regulatory   Allocations  of  Nonrecourse  Deductions  and  Partner  Nonrecourse
Deductions shall be offset by subsequent allocations of items of income and gain
pursuant to this Section A.3 only if (and to the extent)  that:  (a) the General
Partner reasonably determines that such Regulatory Allocations are not likely to
be offset by  subsequent  allocations  under  Section  A.2(a) or Section  A.2(b)
hereof,  and (b) there has been a net decrease in  Partnership  Minimum Gain (in
the  case of  allocations  to  offset  prior  Nonrecourse  Deductions)  or a net
decrease in Partner  Nonrecourse  Debt  Minimum Gain  attributable  to a Partner
Nonrecourse Debt (in the case of allocations to offset prior Partner Nonrecourse
Deductions). The General Partner shall apply the provisions of this Section A.3,
and shall divide the allocations hereunder among the Partners, in such manner as
will minimize the economic  distortions  upon the  distributions to the Partners
that might otherwise result from the Regulatory Allocations.

     A.4 GENERAL ALLOCATION RULES.

          (a) Generally,  all Profits and Losses allocated to the Partners shall
be allocated among them in proportion to their Percentage  Interests,  except as
otherwise  specifically  provided under the terms of this Agreement In the event
Partners are admitted to the  Partnership  on different  dates during any Fiscal
Year,   additional  Units  are  issued  during  a  Fiscal  Year,  or  Units  are
re-allocated  during a Fiscal  Year,  the Profits (or Losses)  allocated  to the
Partners  for each such Fiscal  Year shall be  allocated  among the  Partners in
proportion to the Percentage Interests that each Partner holds from time to time
during  such  Fiscal  Year in  accordance  with  Code  Section  706,  using  any
convention permitted by law and selected by the General Partner.

          (b) For purposes of determining the Profits, Losses or any other items
allocable  to any  period,  Profits,  Losses and any such other  items  shall be
determined  on a daily,  monthly or other basis,  as  determined  by the General
Partner using any method  permissible under Code Section 706 and the Regulations
thereunder.

          (c) For purposes of determining the Partners'  proportionate shares of
the "excess  nonrecourse  liabilities" of the Partnership  within the meaning of
Regulations Section 1.752-3(a)(3), their respective interests in Partner profits
shall be in the same proportions as their Percentage Interests.
