Exhibit 10.2


                             REVOLVING CREDIT NOTE
                                 (this "NOTE")

FOR VALUE RECEIVED, ON OR BEFORE the Termination Date (as defined in the 
Credit Agreement), 1st TECH CORPORATION and DARKHORSE SYSTEMS, INCORPORATED, 
(jointly and severally, "BORROWERS") promise to pay to the order of CHEMICAL 
BANK ("Bank") at its office at 633 Third Avenue, New York, NY 10017 or such 
other location as Bank may designate, in immediately available funds and 
lawful money of the United States of America, the sum of SIX MILLION AND 
NO/100THS UNITED STATES DOLLARS (U.S. $6,000,000.00) or the aggregate unpaid 
amount of all advances hereunder, whichever is lesser, plus interest on the 
unpaid balance outstanding from time to time at a rate per annum equal to the 
lesser of (i) the Stated Rate (as hereinafter defined) from time to time in 
effect or (ii) the Highest Lawful Rate. If the Stated Rate at any time 
exceeds the Highest Lawful Rate, the actual rate of interest to accrue on 
the unpaid principal amount of this Note will be limited to the Highest 
Lawful Rate, but any subsequent reductions in the Stated Rate due to 
reductions in the Prime Rate will not reduce the interest rate payable upon 
the unpaid principal amount of this Note below the Highest Lawful Rate until 
the total amount of interest accrued on this Note equals the amount of 
interest which would have accrued if the Stated Rate had at all times been in 
effect.
     The "STATED RATE" at any time shall be: (i) from the Credit Agreement 
Effective Date through September 30, 1996, a rate equal to the Prime Rate as 
it changed plus 3.0%; and (ii) on and after October 1, 1996, the rate 
indicated by the following chart:

     DETERMINING RATIO            STATED RATE
     ---------------            -----------

     Over 3.0X                  Prime Rate +3.0%
     1.5X to 3.0X               Prime Rate +2.0%
     1.0X top 1.4X              Prime Rate +1.5%
     Less than 1.0X             Prime Rate +1.0%

     The "DETERMINING RATIO" on any date shall be the ratio (determined for 
both Borrowers combined, as of the end of the most recently ended calendar 
month) of (i) Indebtedness to (ii) Annualized EBDITA (Adjusted). Annualized 
EBDITA (Adjusted) shall mean (i) for the first 11 months after the Credit 
Agreement Effective Date, Borrowers' average combined monthly EBDITA 
(Adjusted) (as correctly reported in Borrowers' Compliance Certificates in 
the form of Exhibit C of the Credit Agreement) for all months reported to the 
date the ratio is determined, times twelve; and (ii) thereafter, the sum of 
Borrowers' combined monthly EBDITA (Adjusted) (as correctly reported) for the 
12 months preceding the date the ratio is determined.

     "PRIME RATE" means that rate as determined from time to time by Bank as 
being its prime rate in effect at its principal office in New York City. 
Without notice to Borrowers or any other Person, the Prime Rate shall change 
automatically from time to time as and in the amount by which said prime rate 
shall fluctuate with each such change to be effective as of the date of each 
change in such prime rate. THE PRIME RATE IS A REFERENCE RATE AND DOES NOT 
NECESSARILY REPRESENT THE LOWEST OR BEST RATE. BANK MAY MAKE LOANS AT RATES 
OF INTEREST AT, ABOVE OR BELOW THE PRIME RATE.







     This Note is the Revolving Credit Note described in Section 1.1 of the 
Credit Agreement (Borrowing Base) between Borrowers and Bank dated as of May 
20, 1996 (as amended, restated and supplemented from time to time, the 
"Credit Agreement" and "Agreement") and sometimes referred to therein as the 
Note. Capitalized terms used in this Note have the meanings used in the 
Agreement.

     Accrued and unpaid interest shall be due and payable monthly, beginning 
on June 30, 1996, and continuing on the last day of each month thereafter and 
at Termination Date when all unpaid principal and accrued and unpaid interest 
shall be finally due and payable. Borrowers must make the payments required 
by Sections 1.3, 1.4 and 1.5 of the Agreement.

     Interest shall be computed on the basis of the actual number of days 
elapsed and a year comprised of 360 days, unless such calculation would 
result in a usurious interest rate, in which case interest will be calculated 
on the basis of a 365 or 266 day year, as applicable.

     All past-due principal and, as permitted by applicable law, interest on 
this Note, shall, at Bank's option, bear interest at the Highest Lawful Rate, 
or if applicable law shall not provide for a maximum nonusurious rate of 
interest, at a rate per annum equal to eighteen percent (18%).

     The unpaid principal balance of this Note at any time shall be the total 
amounts advanced by Bank, less the amount of all payments of principal. 
Absent manifest error, the records of Bank shall be conclusive as to amounts 
owed. Subject to the terms and conditions of the Agreement, Borrowers may use 
all or any part of the credit provided for herein at any time before the 
Termination Date.

     Time is of the essence. Borrowers may at any time pay the full amount or 
any part of this Note without the payment of any premium or fee. At Bank's 
sole option, all payments may be applied to accrued interest, to principal, 
or to both.

     If any Event of Default occurs, then Bank may exercise any and all 
rights and remedies under the Loan Documents, at law, in equity or otherwise.

     Each and all Obligators severally waive notice, demand, presentment for 
payment, notice of nonpayment, notice of intent to accelerate, notice of 
acceleration, protest, notice of protest, and the filing of suit and 
diligence in collecting this Note and all other demands and notices, and 
consent and agree that their liabilities and obligations shall not be 
released or discharged by any or all of the following, whether with or 
without notice to them or any of them, and whether before or after the stated 
maturity hereof: (i) extensions of the time of payment; (ii) renewals; (iii) 
acceptances of partial payments; (iv) releases or substitutions of any 
collateral or any Obligor; and (v) failure, if any, to perfect or maintain 
perfection of any security interest in any collateral. Each Obligor agrees 
that acceptance of any partial payment shall not constitute a waiver.

     Bank and any subsequent owner or holder hereof reserves the right, in 
its sole discretion, without notice to Borrowers, to sell participations or 
assign its interest or both, in all or any part of this Note. For purposes of 
this Note, any assignee or subsequent holder of this Note will be considered 
the "Bank," and each successor to each Borrower will be considered a 
"Borrower."





IN WITNESS WHEREOF, Borrowers have executed this Note effective as of the 
Effective Date.
