GENERAL AGREEMENTS

     1. The business of the Borrower shall be continued in its present form and
at the address as shown on page one, and the Borrower will not enter into
changes of its partnership agreement, limited liability company articles of
organization, or, if a corporation, enter into a consolidation, merger, or
permit a majority of its common stock to be transferred, or grant options which
could result in such actions unless the Lender is first notified and consents in
writing to any such change.

     2. The proceeds of the loan or line of credit will be used lawfully and
exclusively for the benefit of the Borrower's business and for the purpose set
forth on page one.

Lender to Borrower, (including, but not limited to checking, deposit accounts,
certificates of deposit, savings accounts, and the like) shall, likewise, secure
the loan or line of credit described on page one. It is the expressed intent to
cross-collateralize all of the borrowings or other indebtedness of Borrower to
the Lender. The breach of the terms of any note, security agreement, mortgage,
pledge, or loan agreement of whatsoever nature between the Borrower and the
Lender shall constitute default and breach of all such agreements, including

and property insurance to protect its assets, the insurance to be in such form

     5. This agreement shall pertain to and govern monies owed by Borrower to
Lender, identified as loan(s) and/or line(s) of credit on page one, including
all renewals, extensions and changes of form related thereto, until the same

     2. The Borrower has full and unencumbered title to all property relied upon
by the Lender as security and to all assets set forth in any financial
statement, unless otherwise indicated in such statement.

     3. The Borrower will keep its books and records in accordance with
generally accepted accounting principles and will deliver balance sheets as well
as profit and loss statements from time to time in a form satisfactory to the

     4. The Borrower agrees that the Lender may itself, or by its authorized
representative, inspect the premises, books, and records of the Borrower during
regular business hours and at reasonable intervals.

     5. As to any real estate which has been, is now, or will be in the future

will now or in the future be allowed in any manner to be exposed to or contain
hazardous or environmentally harmful substances as may be defined or regulated
by any state or federal law or regulation which impacts, in any way, such
substances, except to the extent the existence of such substances has been
presently disclosed in writing to Lender, and Borrower will immediately notify
Lender in writing of any assertion made by any party to the contrary. Borrower
indemnifies and holds Lender and Lender's directors, officers, employees, and
agents harmless from any liability or expense of whatsoever nature, including
reasonable attorney fees, incurred directly or indirectly as a result of
Borrower's involvement with hazardous or environmentally harmful substances as
may be defined or regulated as such under any state or federal law or

third party, will not lend money, encumber any of its assets, or sell any asset,

perfecting Lender's security interests and liens, including all insurance
premiums and title insurance costs, Uniform Commercial Code search fees, and
all, fees incurred by Lender for audits, inspection, and copying of Borrower's
books and records. In addition, any costs associated with the closing of this
loan, attorney fees and other incidental costs shall be paid by Borrower. The
Borrower also agrees to pay all costs and expenses of Lender in connection with

receiver, trustee, or assignment for the benefit of creditors; any voluntary or
involuntary bankruptcy insolvency proceeding; any assessment for taxes (other
than real property taxes) levied by any government entity; or any lien,
attachment, or garnishment by a creditor of the Borrower shall constitute a
default hereof. Borrower shall also be in default if the Lender should, in good
faith, believe the Borrower's ability to repay its indebtedness under this
Agreement, any collateral, or the ability to resort to any collateral, is or
soon will be impaired, time being of the very essence.

I.  REMEDIES ON DEFAULT

     In addition to any other remedies upon an event of Default, Lender shall
have the right to cease to make any further advances under this Agreement, or

Borrower immediately due and payable regardless of the terms of any note or
other evidence of indebtedness between the Borrower and the Lender. No
