     THIS NOTE  PROVIDES FOR INTEREST AT A  FLUCTUATING  RATE PER ANNUM BASED ON
THE PRIME RATE (PLUS ANY APPLICABLE  SPREAD OVER THE PRIME RATE INDICATED BELOW)
ON THE TERMS AND CONDITIONS SET FORTH BELOW.

     This Note is executed  pursuant to the Building Loan Agreement  dated as of
the date of this Note between JORDAN LAKE PRESERVE CORPORATION, a North Carolina
corporation (the  "Borrower") and INDYMAC BANK F.S.B.  dba CONSTRUCTION  LENDING
CORPORATION OF AMERICA (the "Lender") (such Building Loan  Agreement,  as it may
from time to time be  supplemented,  modified and amended,  being referred to in
this  Note as the  "Agreement").  Capitalized  terms  used in this  Note and not
otherwise defined are used with the meanings set forth in the Agreement.

     1. FOR VALUE  RECEIVED,  the  Borrower  promises to pay to the  Lender,  or
order,  at the Lender's  office  located at 155 North Lake  Avenue,  11th Floor,
Pasadena,  California 91101,  Attention:  Construction Lending Division (or such
other  location  specified  by the  Lender  from time to time in  writing),  the
principal  amount of Six  Million  Seven  Hundred  Thousand  and N0/100  Dollars
($6,700,000.00), or so much of such amount as may be advanced by the Lender from
time to time,  together  with  interest as  provided in Section 3 below.  As set
forth in the Agreement, the indebtedness evidenced by this Note is structured as
a revolving line of credit,  with  disbursements  thereof in accordance with the
requirements and conditions therefor set forth in the Agreement.

     2. If not sooner paid,  the principal of this Note shall be payable on July
30,  2002;  provided,  however,  the term of this  Note  shall be  automatically
extended by one (1) year to July 30,  2003 upon  receipt by Lender of the second
installment  of the Loan Fee in the amount of  $74,931.50  on July 30, 2002 (the
"Maturity  Date").  Accrued  interest  shall be payable on the first day of each
calendar month beginning August 1, 2001, on the Maturity Date and on the date of
final  payment of the  principal of this Note in full,  except that any interest
which  accrues after the Maturity  Date or the  acceleration  of the maturity of
this Note shall be payable immediately and without demand.

     3.    (a) The unpaid principal of  this Note outstanding  from time to time
shall bear interest at a fluctuating  rate per annum (computed on the basis of a
year of 360 days) equal at all times to the Prime Rate plus one  percent  (1.0%)
per annum, with each change in such rate taking effect  simultaneously  with the
corresponding  change in the Prime Rate (such fluctuating rate of interest being
referred to in this Note as the "Base Rate").

          (b) Accrued interest not paid when due shall,  from and after the date
when due until the date such  interest is paid,  bear  interest at the Alternate
Rate.

          (c) Notwithstanding  Section 3(a), any principal of this Note not paid
when due (whether at the stated maturity,  by acceleration or otherwise)  shall,
from and after the date when due  until the date such  principal  is paid,  bear
interest at the Alternate Rate.

          (d) As used in this Note:

          "Alternate  Rate" means a fluctuating  rate per annum (computed on the
basis of a year of 360  days)  equal at all  times to the Base  Rate  plus  five
percent  (5.0%)  per  annum,  with  each  change  in  such  rate  taking  effect
simultaneously with the corresponding change in the Base Rate.

          "Prime Rate" means the rate as published in the "Money Rates"  section
of The Wall Street  Journal with changes  thereon to be effective as of the date
of such change. The foregoing notwithstanding, if The Wall Street Journal ceases
to publish the "Money Rates"  section or if there is a suspension of publication
of The Wall Street Journal, then an alternative source for determining the Prime
Rate shall be selected by Lender in its sole discretion."

     4. This Note shall also  evidence  the  obligation  of  Borrower  to pay to
Lender  the  second  installment  of the  $149,863.00  Loan Fee in the amount of
$74,931.50 on the first  anniversary  date of this Note. The full amount of such
Loan Fee shall be deemed fully earned by Lender on the date hereof.

     5.  Irrespective of any acceleration of maturity,  at Lender's option,  the
entire unpaid principal balance evidenced by this Note shall bear interest until
paid at an augmented  annual rate (the "Default Rate") from and after the stated
or  accelerated  maturity of this Note,  or from and after the failure to pay on
the due date any payment due and payable under this Note or under any other Loan
Document (and the  expiration of any  applicable  grace period  provided in this
Note or such  other  Loan  Document  for such  payment),  or from and  after the
occurrence  of any  other  default  (whether  due to the  payment  of  money  or
otherwise)  under any Loan Document (and the expiration of any applicable  grace
period  provided in such Loan Document for the cure of such default);  provided,
however,  that after judgment,  all such sums shall bear interest at the greater
of the Default Rate or the rate  prescribed by applicable law for the accrual of
interest  on  judgments.  The  Default  Rate shall equal the Base Rate plus five
percent  (5%) per annum,  but not  greater  than the  maximum  rate of  interest
permitted by applicable law.

     6.  This  Note may be  prepaid  in  whole  or in part at any  time  without
penalty. In the event of any such prepayment in whole, the second installment of
the Loan Fee in the  amount  of  $74,931.50  evidenced  hereby  shall be due and
payable  regardless  of whether or not such  prepayment in whole occurs prior to
the first anniversary date of this Note. All payments on this Note shall be made
in  lawful  money of the  United  States in same day  funds.  All  advances  and
payments of principal of this Note may be endorsed by the Lender on the attached
schedule.

     7. This Note is the "Note"  referred  to in, and is  entitled to the rights
and benefits of, the  Agreement,  and evidences  advances of the proceeds of the
loan made by the Lender to the Borrower under the Agreement. Among other things,
the Agreement  provides for  acceleration  of the maturity of this Note upon the
happening of certain  stated events and may also contain  additional  provisions
regarding  voluntary and mandatory  prepayments under certain  conditions.  This
Note is secured by the Deed of Trust  executed  by the  Borrower in favor of the
Lender pursuant to the Agreement and by any other collateral agreements referred
to in the Agreement which purport to secure this Note. Upon the occurrence of an
Event of Default,  Borrower shall be liable for all costs and expenses  incurred
by  Lender  in  exercising  any  of  Lender's  rights  and  remedies,  including
reasonable  attorney's  fees.  In  addition,  any  installment  of  principal or
interest due hereunder  not paid within  fifteen (15) days of its due date shall
be subject to a late fee of four percent (4.0%) of such installment due.

     8. This Note shall be governed by, and construed and enforced in accordance
with, the laws of North Carolina.
