      favor of Lender granted by Sea Electronics against the assets of Sea
      Electronics as a result of Sea Electronics becoming an additional named

      "2.2 Term Loan and Equipment Loans.

            (A) Term Loan. Borrower hereby represents and warrants that on
      December 15, 1993, Lender made a term loan to Borrower in the principal
      amount of $3,500,000 (the "Existing Term Loan"), which Existing Term Loan
      is repayable in accordance with the terms of that certain secured
      promissory note dated December 15, 1993, executed by Borrower and payable
      to the order of Lender. Borrower further represents and warrants that as
      of the date of the First Amendment Agreement, the aggregate unpaid
      principal balance of Existing Term Loan is $1,990,326, and such amount is
      unconditionally owed by Borrower to Lender without offset, defense or
      counterclaim of any kind, nature or description whatsoever. Subject to the
      terms and conditions of the First Amendment Agreement, Borrower and Lender
      hereby agree that (i) on the date of the First Amendment Agreement, Lender
      shall make an additional term loan to Borrower in the amount of
      $1,509,674, the proceeds of which shall be used by Borrower solely to
      finance its seasonal working capital needs, and (ii) such additional term
      loan and the Existing Term Loan shall be combined into a single term loan
      of $3,500,000 (the "Term Loan"), which shall be repayable in accordance
      with the terms of the Term Note and shall be secured by the Collateral.

            (B) Equipment Loans - Lender agrees that it will, from time to time
      during the term hereof so long as no Default or Event of Default exists,
      make Loans to Borrower to finance Borrower's purchase of Equipment for use
      in Borrower's business; provided, however, that no Equipment Loan may
      exceed 100% of the actual cost (exclusive of taxes, transportation and
      shipping charges and installation, make-ready fees or expenses) of such
      Equipment. All such Equipment Loans shall be in such amounts as may be
      mutually agreed upon, but in no event to be less than $100,000.00 each, or
      to exceed in the aggregate during the term hereof $750,000.00. The
      Equipment Loans shall be secured by the Collateral, and shall bear
      interest at the rate specified in Section 3.1(A) hereof. Prior to funding
      of an Equipment Loan, Borrower will execute and deliver to Lender an
      Equipment Note to evidence the applicable Equipment Loan. Each Equipment
      Loan will be repayable in monthly principal installments calculated on an
      five-year amortization, beginning the month after the funding of such
      Equipment Loan. Each Equipment Loan will mature simultaneously with the
      termination of the Revolving Credit Loans. Accrued interest on each
      Equipment Loan will be payable monthly, beginning the month after the
      funding of such Equipment Loan.

            (C) Mandatory Prepayments. If Borrower sells any of its Equipment or
      real Property, the proceeds of which exceed $25,000 in the aggregate
      during any fiscal year of Borrower, or if any of the Collateral is taken
      by condemnation, Borrower shall pay to Lender, unless otherwise agreed by
      Lender, as and when received by Borrower and as a mandatory prepayment of
      the Term Loan (or, at Lender's option, such of the other Obligations as
      Lender may elect), a sum equal to the proceeds received by Borrower from
      such sale or condemnation or at Borrower's option, Borrower may use the
      proceeds from

                                        5

      Equipment sales to acquire replacement Equipment in accordance with

      2.08 Amendment to Section 3.1(A). Effective as of the date hereof, Section
3.1(A) of the Loan Agreement is hereby amended by deleting the first sentence
thereof in its entirety and substituting the following two sentences in lieu

            "Outstanding principal on the Loans shall bear interest, calculated

      interest at a fluctuating rate per annum equal to 1.50% above the Base
      Rate, (ii) the Equipment Loans shall bear interest at a fluctuating rate
      per annum equal to 1.50% above the Base Rate and (iii) the Revolving

      Reduction Event, at a fluctuating rate per annum equal to 0.75% above the
      Base Rate and (b) after the occurrence of the Rate Reduction Event (if
      applicable), at a fluctuating rate per annum equal to 0.50% above the Base
      Rate. Each Applicable Annual Rate shall be increased or decreased, as the
      case may be, by an amount equal to any increase or decrease in the Base
      Rate, with such adjustments to be effective as of the opening of business
      on the day that any such change in the Base Rate becomes effective."

      Event of Default, (a) this Agreement shall be in effect, through and
      including December 31, 1998 (the "Original Term"), and (b) unless
      terminated by either party upon at least 180 days notice to the other
      party prior to the end of the Original Term, this Agreement shall
      automatically renew for an additional one year period, through and
      including December 31, 1999 (the "Renewal Term"). Notwithstanding anything
      herein to the contrary, Lender may terminate this Agreement without notice
      upon or after the occurrence of an Event of Default."

      2.11 Amendment to Section 3.3(A). Effective as of the date hereof, Section
3.3(A) of the Loan Agreement is hereby deleted in its entirety, and the
following shall be substituted therefor:

            "(A) Borrower may terminate Lender's agreement to make Equipment
      Loans and the Term Loan at any time, without premium or penalty. Further,
      Borrower may prepay the Equipment Loans and the Term Loan at any time
      during the term of this Agreement, in whole or in part, without premium or
      penalty, but any portions so prepaid

                                       6

<PAGE>

      may not be reborrowed. However, if Borrower chooses to terminate the
      Revolving Credit Commitment and this Agreement in its entirety, Borrower
      shall give Lender at least 30 days prior written notice thereof, and, on
      the designated termination date, all of the Obligations shall become due
      and payable in immediately available funds. At the effective date of any
      such termination of the Revolving Credit Commitment and this Agreement,
      Borrower shall pay to Lender (in addition to the then outstanding
      principal, accrued interest and other charges owing under the terms of
      this Agreement and any of the other Loan Documents), as liquidated damages
      for the loss of the bargain and not as a penalty, an amount equal to (i)
      1.0% of the Termination Amount if such termination occurs during the
      period from October 16, 1995 through December 31, 1996; and (ii) 0.67% of
      the Termination Amount if such termination occurs during the period from
