This Revolving Credit Agreement (the "Agreement") is made as of June 24, 1997,

     line of credit in the amount of $2,000,000 for working capital and
     acquisition purposes; and

ii.  Bank is willing to make available such line of credit as requested by
     Borrower, upon and subject to the terms and conditions set forth in this
     Agreement.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants
contained in this Agreement, Borrower and Bank agree as follows:

1. TERMS OF BORROWING
   ------------------

1.01 Revolving Credit Line.  Subject to the following terms and conditions, Bank
     ---------------------
     agrees to make a line of credit available to Borrower (the "Revolving
     Credit Line") in the maximum amount of $2,000,000 (the "Maximum Line") or,
     if less, the amount of the Cash Flow Limit (defined below), pursuant to
     which Bank will make loans to Borrower (each an "Advance") in such amounts
     as Borrower may request from time to time, the proceeds of which shall be
     used for working capital and future acquisitions. The aggregate outstanding
     principal balance of all Advances made hereunder may not exceed the Maximum
     Line.  Amounts borrowed under the Revolving Credit Line may be repaid prior
     to the Termination Date (defined below) without penalty and may be
     reborrowed subject to the terms hereof.

     Bank's commitment to make Advances hereunder is subject to the conditions
     in Section 3 below and the following limitations:

     a.   Bank's commitment to lend hereunder terminates on June 24, 1998 (the
          "Termination Date"), if not sooner terminated under Section 7 below;

     b.   Bank shall not be obligated to make any Advance which would cause the
          outstanding principal balance of the Revolving Credit Line (the "Line
          Balance") to exceed the Maximum Line or, if less, the Cash Flow Limit;
          and

     c.   Bank shall not be obligated to make any Advance if an Event of
          Default, as defined in Section 6 below, or an event which, with the
          giving of notice or lapse of time, or both, would become an Event of
          Default (a "Potential Default"), has occurred and has not been cured
          by Borrower or waived by Bank.

1.02 Line Note.  Borrower's indebtedness to Bank for amounts borrowed under the
     ---------
     Revolving Credit Line and for interest accrued thereon shall be evidenced
     by Borrower's promissory note to Bank, on Bank's standard form for
     commercial promissory notes and otherwise satisfactory to Bank, in the
     principal amount of the Maximum Line (the "Line Note").

1.03 Interest.  Borrower agrees to pay interest on the Line Balance from time to
     --------
     time as provided herein.  Interest will accrue on the daily outstanding
     Line Balance at a fluctuating rate per annum equal to the applicable
     "Reserve Adjusted LIBOR Rate" plus the applicable margin as set forth below
     for the selected Interest Period (see the attached Exhibit A which will be
                                                        ---------
     attached to and incorporated into the Line Note for terms and definitions
     which will apply while the interest rate is based on a Reserve Adjusted
     LIBOR Rate). Borrower shall have the option to select an Interest Period on
     each new Advance.   The interest rate for any new Advance or any Advance
     outstanding on a one-month reset daily basis will be subject to further

                                       1

 
     adjustment quarterly, as of the first day of each fiscal quarter, as
     follows:  When Borrower's ratio of Debt (as defined in Section 5.02) to
     Annualized Cash Flow (as defined in Section 1.04) is within one of the
     ranges set forth below, then the "margin" or "spread" to be added to the
     applicable Reserve Adjusted LIBOR Rate shall be the rate per annum set
     forth below opposite such range:

               Range of Debt/Annualized
               Cash Flow Ratios                Margin
               -----------------               ------

               (less than)  1.00:1              2.25%
               1.00:1 (= or less than) 2.50:1   2.50%
               (greater than)  2.50:1           2.75%

     Accrued interest shall be due and payable (i) on the first day of each
     month, (ii) at maturity of the Line Note and (iii) on demand after such
     maturity.  After the occurrence of an Event of Default or after maturity or
     any acceleration of maturity of the Line Note, at Bank's option, the
     interest rate applicable to the Line Balance may be increased as provided
     in the Line Note and Borrower agrees to pay any such increased interest.
     Interest shall be computed using the actual number of days in the period
     for which such computation is made and a per diem rate equal to 1/360 of
     the fluctuating rate per annum.

1.04 Cash Flow Limit.  The "Cash Flow Limit" means from time to time an amount
     ---------------
     equal to the result of multiplying Borrower's Annualized Cash Flow by 3.5
     where "Annualized Cash Flow" means Borrower's earnings before interest,
     taxes, depreciation and amortization calculated at the end of each quarter
     for the previous four quarters (i.e. on a four-quarter trailing basis).

1.05 Repayment of Principal.  Borrower agrees to repay all Advances made
     ----------------------
     hereunder.  The Line Balance will be due and payable in full at the
     maturity of the Line Note, which will be June 24, 1998 subject to
     acceleration upon the occurrence of an Event of Default.

1.06 Method of Borrowing.  Requests for Advances may be submitted by Borrower in
     -------------------
     writing or by telephone.  Bank shall be entitled to honor any such request
     it reasonably believes to be genuine, whether or not the person making the
     request is named as an authorized person in any corporate resolution or
     instruction furnished Bank by Borrower.  Advances shall be disbursed only
     by deposit to a demand deposit account maintained by Borrower at Bank.
     Proceeds of an Advance shall be disbursed on the Banking Day (as defined in
     the Colorado Uniform Commercial Code) Bank receives Borrower's request if
     such request is received before 2:00 p.m. Denver time on such day, and on
     the next Banking Day if received at or after 2:00 p.m. on such day, and in
     either case the conditions of Section 4 are met.

1.07 Letters of Credit.  In the event and to the extent Bank issues a letter of
     -----------------
     credit (an "L/C") on behalf of Borrower under the Revolving Credit Line in
     lieu of an advance, the Maximum Line shall be considered utilized by the
     amount of such L/C.  Borrower shall pay fees for any such L/C at the time
     of issuance according to Bank's schedule of fees relating to letters of
     credit in effect from time to time; and Borrower shall execute Bank's then
     current standard form application and agreement for such L/C.  Amounts
     drawn under any such L/C and honored by Bank but not immediately reimbursed
     by Borrower to Bank shall become an Advance hereunder in such amount at
     such time evidenced by the Line Note and subject to all the terms of this
     Agreement, whether or not any Event of Default or Potential Default has
     occurred.  No such L/C shall expire later than the Termination Date.

1.08 Loan Fee.  Borrower agrees to pay Bank a fee of $2,000.00, being one-tenth
     --------
     of one percent (0.1%) of the Maximum Line, payable in advance on the date
     of execution hereof by Borrower.

1.09 Annual Rest Period.  Notwithstanding that the Line Balance is not due in
     ------------------
     full until maturity, Borrower agrees to reduce the Line Balance to zero and
     refrain from reborrowing for a period of 30 consecutive days commencing at
     a time selected by Borrower not less than 30 days prior to the Termination
     Date.
