Appendix A

6.04  Purchase of Interests of Limited Partners.

      (a) The Partnership shall use its best efforts to repurchase Units on an
annual basis from Limited Partners desiring to have such Units repurchased upon
the terms and conditions set forth below.

      (b) A Limited Partner wishing to have some or all of his or her Units
repurchased by the Partnership must mail or deliver a written request to the
Partnership indicating his or her desire to have such Units repurchased. Any
such request must be received by the Partnership on or before July 1 immediately
preceding the January 1 date on which the repurchase is to be effective. Any
such request to have Units repurchased shall constitute an offer by the Limited
Partner to sell such Units and shall be irrevocable. If the Partnership does not
have sufficient funds to purchase all of the Units so offered or is otherwise
prohibited from purchasing all of the Units so offered, the Partnership will
purchase Units in the order in which effective offers are received from offerors
to the extent that the Partnership has funds available therefor and is not
prohibited from purchasing Units.

      (c) The purchase price for any Units purchased by the Partnership will
equal 90% of the Fair Market Value of the Units. "Fair Market Value" of a Unit
shall mean the fair market value as determined by the General Partner in its
sole and absolute discretion, after consultation with an adviser selected by the
General Partner. Any repurchase of Units by the Partnership shall be effective
as of January 1 of the year following the year in which the corresponding offer
was timely made pursuant to Section 6.04(b). Any Limited Partner whose Units are
to be repurchased shall execute and deliver such transfer and other documents
and instruments as the Partnership may reasonably request. Any Units repurchased
by the Partnership shall be cancelled and shall not be reissued by the
Partnership.

      (d) In fulfilling the Partnership's obligation to use best efforts to
repurchase Units for which offers have been timely made pursuant to Section
6.04(b), the General Partner shall be authorized to take such steps as it deems
appropriate, in its sole discretion, including without limitation the
disposition of assets of the Partnership (including assets owned by Sponsored
Partnerships which have been acquired by the Partnership) and incurring
indebtedness on behalf of the Partnership.

      (e) Notwithstanding anything herein to the contrary, no Unit shall be
repurchased by the Partnership pursuant to this Section 6.04 if:

            (i)   The Partnership is insolvent or such repurchase would render
                  the Partnership insolvent;

            (ii)  Such repurchase would impair the capital or operations of the
                  Partnership;

<PAGE>

            (iii) Such repurchase would contravene any provision of federal or
                  state securities laws;

            (iv)  Such repurchase would cause the Partnership to terminate as a
                  partnership under the Code;

            (v)   Such repurchase would cause the Partnership to fail to qualify
                  for one or more of the "safe harbors" contained in Treasury
                  Regulation Section 1.7704-1(e) through (j) that would preclude
                  the Partnership from being treated as a "publicly traded
                  partnership" within the meaning of Section 7704 of the Code;
                  or

            (vi)  The General Partner determines such repurchase would otherwise
                  not be in the best interests of the Partnership.

      (f) If the Partnership is unable to repurchase any Units, the Partnership
shall use its best efforts to arrange for a purchase by a third party or
parties, including without limitation members of the General Partner, of such
Units; provided, however, that no such purchase shall be effected if it would
not be permitted under the terms of Section 6.04(e). In addition, the
Partnership shall have the right to satisfy its obligations under Section
6.04(a) by arranging for the purchase of Units by any such third party or
parties for the price set forth in Section 6.04(c).

      (g) Any request for repurchase of Units by a Limited Partner pursuant to
Section 6.04(b) shall be binding on such Limited Partner's successors, heirs and
assigns.<PAGE>

Re:     Wells  Fargo  Business  Credit/Rockshox,  Inc.
        ----------------------------------------------
Dear  Chris:

     This  letter is written in reference to the Amended and Restated Credit and
Security  Agreement  dated  as  of  June  28,  2000  between Rockshox, Inc. (the
"Borrower")  and  Wells  Fargo  Business  Credit, Inc. (the "Lender") (as may be
 --------                                                    ------
amended  or restated from time to time, the "Agreement").  All capitalized terms
                                             ---------
not  defined  in  this  letter have the meanings given to them in the Agreement.

     You  have  asked  the  Lender  to  amend  the Agreement to provide you with
additional  credit,  and the Lender is considering whether it will enter into an
amendment.  In  the  meantime,  the  Lender is willing to accommodate you on the
terms  set  forth  in  this  letter.

     The  Lender  may  in its discretion, as a special short-term accommodation,
make  Revolving  Advances  in  excess  of the Borrowing Base in an amount not to
exceed  One  Million Two Hundred Thousand Dollars ($1,200,000) (individually and
collectively,  the  "Special Accommodation"); provided that no Revolving Advance
                     ---------------------    --------
(including  any  Special  Accommodation)  shall be made in excess of the Maximum
Line.  Each  Special  Accommodation  shall  be deemed to be a Revolving Advances
under the Agreement; provided however, that the Special Accommodation shall bear
                     -------- -------
interest  at  a  rate  equal to the Base Rate plus three percent (3%).  You will
repay  the  Special  Accommodation in full, together with accrued interest, upon
demand by the Lender at any time and in the Lender's sole discretion, but in any
event  not  later  than  August  31,  2001.

     As  consideration for the Special Accommodation, the Borrower agrees to pay
Lender  an  non-refundable  accommodation  fee  in the amount of Twelve Thousand
Dollars  ($12,000),  which fee shall be fully earned and payable upon Borrower's
acceptance  of  this  letter.

     Except  as  modified by this letter, the provisions of the Agreement remain
unchanged  and  continue  in  full  force  and  effect.

     By  your  execution  of  this  letter below, you confirm that no Default or
Event  of  Default  exists  under  the Agreement (other than certain Defaults or
Events of Default which have been disclosed to Lender prior to the date hereof),
that  the  representations  and  warranties  of  the  Borrower  set forth in the
Agreement are true and correct on the date of this letter as if made on the date
of  this  letter, and that the Borrower has taken all corporate action necessary
in order to execute and deliver this letter and to perform its obligations under
this  letter.

     The  Lender's  willingness  to  extend  the  Special Accommodation is not a
waiver  of any existing or future Events of Default.  Upon the occurrence of any
Events of Default after the date of this letter, or in the event that the Lender
learns of any Event of Default that occurred prior to its date, the Lender shall
be  free  to  exercise  any and all of its various rights and remedies under the
Agreement.  Furthermore,  nothing  contained  in  this  letter  shall  diminish,
prejudice  or  waive  any of Lender's rights and remedies under the Agreement or
applicable  law,  and  Lender  hereby  reserves all of such rights and remedies.
