         RE:      AMENDMENT #2 TO LOAN AND SECURITY AGREEMENT

Dear Jim:

         This letter will confirm our conversation of February 24, 1999.

         Section 3.1.1b of the First Amendment to the loan and security
agreement dated December 30, 1998 is amended to delete the following words
"(after first deducting from such eligible Receivables a dilution reserve to
account for dilution in excess of five percent (5%) to be established at
Lender's sole discretion and to be adjusted quarterly at Lender's sole
discretion on a trailing twelve-month basis)."

         Add Section 3.1.3b - establish a new sublimit of the revolving lines to
issue letters of credit (standby-or commercial) in an amount up to $3 million.

         Section 13.14 of the Loan and Security Agreement dated June 20, 1997 is
revised to delete the minimum EBITDA amount of $3 million, and replace it with a
minimum EBITDA of $7 million at 6/30/99 and $8 million at 12/31/99.

         All other terms and conditions of the above agreements remain
unchanged. Please sign, date and fax back a copy indicating your agreement with
the above. I will forward an original copy by regular mail.

                                    Sincerely,

                                    [FINOVA] Capital Corporation

                                ADDENDUM NO 2 TO
                    MANUFACTURING AND DISTRIBUTION AGREEMENT

         This is Addendum No 2 to the Manufacturing and Distribution Agreement
between Rockford Corporation ("Rockford") and Path Group Inc. ("Path Group")
dated June 11, 1998, which was effective on July 1, 1998 and modified by an
Addendum effective on July 30, 1999 (as modified by Addendum No 1, the
"Agreement").

         The effective date of this Addendum is January 1, 2000. It is effective
through the last day of the term of the Agreement.

         1.       ROCKFORD'S RELATIONSHIP WITH LIGHTNING AUDIO. Rockford has
                  informed Path that the restrictions in Section 3 of Addendum
                  No 1 are interfering with sales growth of Connecting Punch
                  products because of the lack of co-ordination in sales efforts
                  between the Lightning Audio sales organisation and the
                  Rockford sales organisation. Accordingly, Section 3 of
                  Addendum No 1 is deleted in its entirety. Rockford is
                  authorised to combine the Rockford and Lightning Audio sales
                  organisations, manufacturers' representatives, and
                  distributors in any manner Rockford deems appropriate. The
                  provisions relating to minimum sales of Connecting Punch
                  Products to Best Buy are terminated by this amendment and
                  replaced by the new provisions in Section 2 of this Addendum
                  No. 2.

         2.       MINIMUM SALES GOALS AND PAYMENT. Rockford shall use its best
                  efforts throughout the remaining term of the Agreement to
                  cause sales (which shall be defined in this Addendum as "gross
                  shipped sales") of Connecting Punch products to grow at a rate
                  not less than the sales growth rate for all car audio
                  products.

                  (a) Achievement of this goal shall be measured by comparing
                      the growth in worldwide sales of Connecting Punch products
                      to the growth in total car audio industry sales worldwide
                      (including amplifiers, source units, speakers, and
                      accessories). The parties agree that they will estimate
                      car audio sales growth worldwide using the following
                      computation:

                      (1)  car audio sales growth for the United States will be
                           based on market data provided by NPD Intelect Market
                           Research; and

                      (2)  car audio sales growth for the rest of the world will
                           be assumed to be (a) 23% during the year 2000 (this
                           estimate is (*) of Rockford's projected sales growth
                           for Connecting Punch products for 2000 and is an
                           agreed fixed figure) and (b) the same as the United
                           States sales growth during 2001 based on data
                           provided by NPD Intelect Market Research.

                      Sales growth will be measured on a quarterly basis,
                      comparing sales for the current quarter to sales for the
                      comparable quarter in the prior year. This will result in
                      the following comparisons for the remainder of the
                      Agreement term: (1) 1st through 4th Quarters of 2000 each
                      compared to the same quarter in 1999 and (2) 1st and 2nd
                      Quarters of 2001 each compared to the same quarter in
                      2000. The required sales of Connecting Punch products will
                      be computed based on:

                     (A) actual Connecting Punch sales in the United States for
                         the comparable quarter of the prior year increased by
                         the United States market growth rate computed using (1)
                         above; plus

                     (B) actual Connecting Punch sales in the rest of the world
                         for the comparable quarter of the prior year increased
                         by the rest of the world market growth rate computed
                         using (2) above.

                      This total will be compared to actual aggregate Connecting
                      Punch sales for the quarter. The only sales goal Rockford
                      must meet is an aggregate and there are not subgoals for
                      US and rest of world sales.

                  (b) If sales of Connecting Punch products fail to equal or
                      exceed the quarterly growth goals then Rockford will pay
                      Path Group a royalty equal to (*) of:

                      (1)  The shortfall in current quarter Connecting Punch
                           sales (compared to the base quarter increased by the
                           industry average sales growth through the current
                           quarter); reduced by

                      (2)  Sales in excess of the required growth rate for prior
                           quarters.

                      (Example: assume current quarter sales of (*), base
                      quarter sales of (*), combined US and rest of world sales
                      such that the required growth of Connecting Punch sales
                      since the comparable quarter of the prior year is (*), and
                      that all prior quarter's sales exceeded goal by an
                      aggregate of (*). Then the quarter sales goal is (*), and
                      there is a current quarter shortfall of (*). This is
                      partially offset by the (*) prior excess, so a (*) royalty
                      is payable on the (*) shortfall. The royalty due is (*)).

                  (c) If sales of Connecting Punch Products fail to exceed the
                      actual sales of Connecting Punch products for the
                      comparable quarter of the prior year, then Path Group's
                      royalty will increase to (*) for that portion of the
                      shortfall that is less than the comparable quarter's
                      sales. (Example: use the same data as above, but assume
                      that current quarter sales are (*). The current quarter
                      shortfall is (*), offset by the (*) excess for prior
                      quarters, leaving a (*) shortfall subject to royalty. Of
                      this amount, (*) minus the (*) excess for prior quarters,
                      or (*), is less than actual sales for the base quarter.
                      Royalty due is (*) of (*) plus (*) of (*), a total of (*)
                      plus (*) equals (*))

                  (d) The royalty, if any, shall be paid by the 14th day after
                      the later of (1) the end of the quarter or (2) Rockford's
                      receipt of the Intelect data allowing computation of the
                      industry growth rate for the quarter. Rockford confirms
                      that it ordinarily receives the Intelect data within 35-40
                      days after a quarter ends and agrees that it shall make
                      the royalty payment (if any is due) by the 50th day after
                      the end of the quarter even if it receives the Intelect
                      data later than the 36th day after the end of the quarter.
                      Rockford shall provide, by the same date, a sales report
                      identifying the actual sales of Connecting Punch product
                      and the required sales based on the Intellect data.
                      Rockford will send a facsimile to Path Group confirming
                      the date it received the Intelect data for each quarter.

         3.       CONSOLIDATION OF SHIPMENTS. Section 12 of Addendum No 1,
                  restricting consolidation of Rockford and Lightning Audio
                  products, is terminated and Rockford is free to consolidate
                  shipments to the extent it deems necessary.

         4.       LIGHTNING AUDIO DISTRIBUTION IN THE UNITED KINGDOM. During the
                  term of the Agreement, Rockford grants to Path Group's
                  affiliate Car Audio Labs ("CAL") a first right of refusal to
                  distribute Lightning Audio products in the United Kingdom.
                  Before offering the Lightning Audio line to any other U.K.
                  distributor during the term of the Agreement, Rockford will
                  give CAL 15 business days notice of the proposed terms on
                  which Rockford will offer the distribution rights for the
                  United Kingdom. Rockford's offer will specify the terms of
                  distribution, including minimum sales, minimum required scope
                  of distribution and other terms. CAL must accept or reject the
                  proposed terms within 15 business days after Rockford gives it
                  notice of the terms. If CAL rejects the terms, then Rockford
                  may offer the distribution rights to any third party but only
                  on the terms offered to CAL or on terms less favorable to the
                  new distributor than those offered CAL.

         5.       CONTINUATION OF AGREEMENT. Except as amended in this Addendum
                  No 2, the Agreement continues in full force and effect and
                  both parties retain their rights and obligations under the
                  Agreement.
