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.

     3. All collateral security given to secure the loan or line of credit shall
also secure all of the other obligations of the Borrower to the Lender of
whatsoever nature, past, present, or future. All collateral security given for
other obligations of the Borrower to the Lender, together with any debt from
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
this agreement.

     4. The Borrower will at all times maintain in full force adequate liability
and property insurance to protect its assets, the insurance to be in such form
and such amounts as the Lender, at its sole discretion, may require.

     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

Borrower Warrants:

     1. All representations and statements of whatever nature made or delivered
to the Lender at any time prior to, contemporaneous with, or subsequent to this
agreement have been, are, or shall be true in all respects.

     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
Lender.

     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
owned or occupied by Borrower, that such real estate has not in the past, nor
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
regulation.

other indebtedness for borrowed money, become a guarantor or surety for any
third party, will not lend money, encumber any of its assets, or sell any asset,
except in the ordinary course of Borrower's business, without the written
permission of the Lender. For the purposes of this section, the sale of accounts
is deemed to be borrowing money.

     The Borrower agrees to pay all of the Lender's expenses incidental to
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
the enforcement of Lender's rights and remedies under this agreement, the
Related Documents, and any other agreements between the Borrower and Lender in
connection with any amendments, modifications, waiver of consent with respect to
this agreement, including reasonable attorney fees.

due; any breach or default of any term, condition or warranty of this agreement
or any other agreement between the Borrower and the Lender; any appointment of a
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.

     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
