          -----------------------
in effect as of the date hereof or as hereafter adopted or amended in any
jurisdiction where the Collateral is or may from time to time be located.

     2. Loans and Interest.
        ------------------

     2.1 Loans.  The Bank proposes to make the following loans to the
         -----
Borrower:

     2.1.1 Automated Revolving Credit Loan.  The Bank will make a revolving
           -------------------------------
line of credit loan ("LOC Loan") to Borrower in an aggregate amount not to
exceed at any one time outstanding the lesser of (i) $4,500,000.00 or (ii)
the sum of (a) the lesser of $1,500,000.00 or 40% of the cost or market
value, whichever is lower, of Eligible Inventory, and (b) 85% of the
outstanding amount of Eligible Accounts (the sum of (a) and (b) being
herein referred to as the "Borrowing Base") (the lesser of (i) or (ii)
being referred to hereinafter as the "Maximum LOC Loan Amount").  Should
the outstanding amount of the LOC Loan at any time exceed the Maximum LOC
Loan Amount, Borrower shall on demand immediately repay such excess amount.
All such loans will be made from time to time in the absolute discretion of
the Bank, and neither this Agreement nor any loans or other action by the
Bank shall obligate the Bank to make further loans to the Borrower.  Such
loans may be made in excess of the Maximum LOC Loan Amount in the sole
discretion of the Bank.   The LOC Loan shall be for an initial term of three
(3) years, and may be renewed annually thereafter on the anniversary of the
effective date of the LOC Note (defined herein) at the sole discretion of
the Bank.

At such times as may from time to time be required by Bank, but at least
once each month during the term of the LOC Loan, Borrower shall provide
Bank with a true and correct Borrowing Base Certificate, in form attached
hereto as Exhibit A and made a part hereof, stating the then-current
Borrowing Base.  If the outstanding amount of the LOC Loan at any time
exceeds the Maximum LOC Loan Amount, based on the then-current Borrowing
Base, then Borrower shall pay to Bank all such excess amounts immediately
on demand.  All advances under the LOC Loan will be made from time to time
in the absolute discretion of the Bank, and neither this Agreement nor any
loans or other action by the Bank shall obligate the Bank to make further
advances to the Borrower.  The Bank's maximum commitment hereunder shall be
reduced by the amount of outstanding letters of credit issued by the Bank
for the benefit of Borrower, and any banker's acceptances and time drafts
resulting therefrom.

     2.1.2 Term Loan.  The Bank will make a Term Loan ("Term Loan") to
           ---------
Borrower in the amount of $1,000,000.00 ("Term Loan Amount").  The Term
Loan shall be for a term of five (5) years as more particularly set out in
the Term Loan Note (defined herein).

<PAGE>  5

     2.1.3 Loans.  The LOC Loan and the Term Loan listed in this Section 2.1
           -----
shall be herein collectively called the "Loans".

     2.2 Evidence of Loans. The Loans shall be evidenced by a Revolving
         -----------------
Credit Promissory Note in the principal amount of $4,500,000.00 and a Term
Loan Note in the principal amount of $1,000,000.00 (collectively the "Notes")
in forms satisfactory to Bank.  The Notes shall bear interest on the daily
outstanding balance thereof at the rates set forth in such Notes.

     2.3 Interest Rate.  Amounts advanced to Borrower under the Notes shall
         -------------
bear interest  at (i) a fluctuating rate equal to the Prime Rate  (as defined
herein) charged by Bank, minus one-quarter of one percent (.25%) ("Prime Rate
Election"); or (ii) at a fixed rate equal to the relevant Quoted LIBOR Rate
plus two and one-half percent (2.50%) per annum, as elected by Borrower in
the manner set out herein ("LIBOR Rate Election").

     Interest shall be calculated on a 360-day year basis and shall be due
and payable on the first day of each calendar month (but charged based on
actual days) during the term of and at maturity of the respective Notes.  In
the case of a Prime Rate Election, the interest rate shall be adjusted,
whenever necessary, to reflect any change in the Prime Rate then in effect
at the Bank, and such adjustment shall be effective on the date such change
is announced as effective by the Bank.  Such new rate shall remain in effect
until the next date an adjustment is required or until the Borrower makes a
LIBOR Rate Election or the respective Note is paid in full.

     2.3.1 Interest Periods.   Upon closing of the Loans, or at the time
           ----------------
Borrower gives any notice of borrowing relating to the LOC Loan, or at the
time Borrower gives notice of conversion of any Loan to a Quoted LIBOR Rate,
which notice shall be given at least three (3) Business Days prior to the
expiration of an existing Interest Period, and provided Borrower is not
otherwise in default hereunder, Borrower shall have the right to elect the
Interest Period applicable to a Quoted LIBOR Rate Election by giving the
Bank notice thereof, which Interest Period shall be a thirty (30), sixty
(60), ninety (90) or one hundred eighty (180) day period, provided, however,
that Borrower shall have no right to elect an Interest Period that would
extend beyond the maturity date of the LOC Loan or the Term Loan.  In the
case of  the LOC Loan, the Interest Period may be selected at the time a
request for an advance is made, in the manner required by the Bank for
giving such notice.  In the case of both the LOC Loan and  the Term Loan,
the Interest Period and applicable interest rate may also be selected by
giving notice in accordance with Section 2.3.2 below.  The Interest Period
may commence at any time after proper notice, and each Interest Period
occurring thereafter, if any, in respect of such a Loan shall commence on
the day on which the next preceding

<PAGE>  6

Interest Period expires.  If any Interest Period would otherwise expire on a
day which is not a business day, such Interest Period shall expire on the
next succeeding business day.  If upon the expiration of any Interest Period
for a Quoted LIBOR Rate Election, Borrower has failed to repay the borrowing
or elect a new Interest Period to be applicable, Borrower shall be deemed to
have elected to convert to or continue (as the case may be) with a Prime Rate
Election effective as of the expiration date of such current Interest Period.

     2.3.2 Continuation and Conversions.  Provided that no Event of Default
           ----------------------------
then exists, Borrower shall have the option, subject to the provisions of
Sections 2.3.1 and 2.3.3 and the following provisions of this Section 2.3.2,
on the first day following expiration of an Interest Period in the case of a
Quoted LIBOR Rate Election  or at any time in the case of a Prime Rate
Election, to continue a previously selected Quoted LIBOR Rate Election for
an additional Interest Period or to convert all or a portion of the
outstanding principal amount of under any Prime Rate Election to a Quoted
LIBOR Rate Election, provided that the outstanding principal amount of
Loans being continued as or converted into a Quoted LIBOR Rate Election
shall be at least Two Hundred Fifty Thousand Dollars U.S. ($250,000.00).
Each such conversion shall be effected by Borrower giving the Bank prior
notice in the form as required by the Bank, specifying the Loan and amount
of such Loan to be so continued or converted, and the Interest Period.

     2.3.3 Increased Costs, Illegality Etc.
           -------------------------------

     A. In the event the Bank shall have determined (which determination
shall, absent manifest error be final and conclusive and binding upon all
parties):

          (i)   on any date for determining the rate applicable to any Quoted
LIBOR Rate Election for any Interest Period, that by reason of any changes
arising after the date of this Agreement affecting the interbank Eurodollar
market, adequate and fair means do not exist for ascertaining the applicable
interest rate on the basis provided for in the definition of such Quoted
LIBOR Rate Election; or

          (ii)  at any time, that by reason of (x) any change since the date
of this Agreement in any applicable law or governmental rule, regulation,
guideline or order (or any interpretation thereof and including the intro-
duction of any new law or governmental rule, regulation, guideline or order)
(such as for example, but not limited to, a change in capital adequacy
requirements or in official reserve requirements, but, in all events,
excluding reserves required under Regulation D to the extent included in
the computation of the Quoted LIBOR Rate and/or (y) other circumstances
affecting a Bank or the interbank Eurodollar market or the position of such
Bank in such market, the Quoted LIBOR Rate or

<PAGE>  7

T-Bill Rate shall not represent the effective pricing to such Bank for
funding or maintaining the affected Quoted LIBOR Rate Election; or

          (iii) at any time, that the making or continuance of any Quoted
LIBOR Rate Election has become unlawful by compliance by a Bank in good
faith with any law, governmental rule, regulation, guideline or order, or
has become impracticable as a result of a contingency occurring after the
date of this Agreement which materially and adversely affects the interbank
Eurodollar market; then, and in any such event, the Bank shall on such date
give notice to Borrower of such determination.  Thereafter, (x) in the case
of clauses (i) and (ii) above, Borrower shall pay to each Bank, upon written
demand therefor, such additional amounts (in the form of an increased rate
of, or a different method of calculating, interest or otherwise as such Bank
in its sole discretion shall determine) as shall be required to cause such
Bank to receive interest with respect to its affected Quoted LIBOR Rate
Election at a rate per annum which shall equal the effective pricing to the
Bank to make or maintain such Quoted LIBOR Rate Election, respectively, plus
2.25 percent per annum (a written notice as to additional amounts owed such
Bank, showing the basis for the calculation thereof, submitted to Borrower
by such Bank shall, absent manifest error, be final and conclusive and
binding upon all of the parties hereto) and (y) in the case of clause (iii),
take one of the actions specified in Section 3.3.3.C. below, as promptly as
possible and, in any event, within the time period required by law.

     B. If the Bank determines that (i) maintenance of any Quoted LIBOR
Rate Election would violate any applicable law, rule, regulation, or
directive, whether or not having the force of law, (ii) deposits of a type
and maturity appropriate to match fund any Quoted LIBOR Rate Election are
not available , (ii) the Quoted LIBOR Rate does not accurately reflect the
cost of making or maintaining a Quoted LIBOR Rate Election, then the Bank
shall suspend the availability of the affected rate option and require any
Quoted LIBOR Rate Election outstanding under an affected rate option to be
repaid.

     C. At any time that any of its Quoted LIBOR Rate Elections are affected
by the circumstances described in Section 2.3.3.A.(iii), Borrower shall
either (x) if the affected Quoted LIBOR Rate Election is then being made
pursuant to an initial borrowing or a conversion, cancel said borrowing or
conversion by giving the Bank telephonic notice confirmed in writing thereof
on the same date that Borrower was notified by the Bank pursuant to Section
2.3.3.A, or (y) if the affected Quoted LIBOR Rate Elections are then
outstanding, upon at least two (2) Business Days' notice to the Bank,
require the Bank to convert each affected Quoted LIBOR Rate Election into a
Prime Rate Election.

     2.3.4 Compensation.  Borrower shall compensate the Bank upon written
           ------------
request (which request shall set forth the basis for requesting such

<PAGE>  8

amounts), for all reasonable losses, expenses and liabilities (including,
without limitation, any interest paid by the Bank to lenders of funds
borrowed by them to make or carry  a Quoted LIBOR Rate Election to the extent
not recovered by the Bank in connection with the re-employment of such funds),
which the Bank may sustain: (i) if for any reason (other than a default by the
Bank) a borrowing of, or conversion from or into, Quoted LIBOR Rate Election
does not occur on a date specified therefor in a notice of borrowing or
notice of conversion (whether or not withdrawn), or (ii) as a consequence of
any other default by Borrower to repay its Quoted LIBOR Rate Elections when
required by the terms of this Agreement.

     2.3.5 Rate Adjustment.  Notwithstanding anything to the contrary
           ---------------
contained herein, the Interest Rate charged under the Notes shall be reduced
for the remaining term of each such Note to (i) a fluctuating rate equal to
the Prime Rate charged by Bank, minus one half of one percent (.50%); or (ii)
a fixed rate equal to the relevant Quoted LIBOR Rate plus two and one quarter
percent (2.25%), effective December as of January 1, 2001 if the following
conditions are satisfied:

          a. Borrower's Debt Service Coverage Ratio (as defined in Section
             5.16 hereof) shall be greater than 2.00 to 1.00 for the year
             ending December 31, 2000;

          b. Borrower's ratio of Consolidated Liabilities to Consolidated
             Tangible Net Worth (both as defined in Section 5.16 hereof)
             shall be not more than 2.25 to 1.00 as of December 31, 2000; and

          c. There has not occurred an Event of Default hereunder or under
             the any loans from Bank to Lytton Incorporated, either now
             existing or hereafter made ("Lytton Loans").

          In the event the above conditions are satisfied, Borrower agrees
to execute and deliver to Bank, an Amended and Restated LOC Note and an
Amended and Restated Term Loan Note, each setting out the new interest rate
set out herein, which new Notes shall be effective as of January 1, 2001.

     2.4 Loan Payments.  All payments of interest, principal and all other
         -------------
amounts owing hereunder or under the Notes shall be made by the Borrower to
the Bank in immediately available funds at its principal office in Dayton,
Ohio or at such other place as the Bank may designate in writing, at such
times as shall be set forth herein or in the Notes.  Borrower hereby
authorizes Bank, at Bank's option, to charge any account or charge or
increase any Loan balance of Borrower at Bank for the payment or repayment
of any interest or principal of the Loans or any fees, charges or other
amounts due to Bank hereunder.

interest in all of Guarantor's accounts, inventory, equipment and general
intangibles (as those terms are defined in the Uniform Commercial Code as

9, 2000.  In addition, Guarantor shall execute and deliver to Bank, as
additional security for the Guaranty, a Conditional Assignment of Lease

other agreement to which the Borrower is a party or by which it is bound,
which breach or default would result in the creation, imposition or

interest granted to the Bank hereunder;

     7.2 Notice of Assignment.  Upon the occurrence and continuance of an
         --------------------
Event of Default beyond any applicable cure periods, the Bank shall have the
right at any time to notify Debtors of its security interest in the Accounts

to time designate, as attorney-in-fact for the Borrower to (a) receive, open
and dispose of all mail addressed to the Borrower and take therefrom any
payments on or proceeds of Accounts; (b) take over the Borrower's post

time credited by, or due from Bank to Borrower or Guarantor shall at all
times constitute additional security for the amount of the Notes then
outstanding with interest and may be set off against any of said
indebtedness to the Bank at any time, whether or not other security held
by the Bank is considered by the Bank to be adequate.  In addition, any and
all instruments, documents, monies, securities, goods, choses in action,
chattel paper and any other property of Borrower or Guarantor, or in which
Borrower or Guarantor has any interest, tangible or intangible, and the
proceeds thereof, which now or hereafter are at any time in the custody or
possession of the Bank or any third party acting in the Bank's behalf,
without regard to whether the Bank received the same in pledge, for safe-
keeping, as agent for collection or transmission or otherwise or whether
the Bank has conditionally released the same, shall constitute additional
security for the Notes and may be applied at any time to the liability
represented thereby which is then due, whether by acceleration or otherwise.
