         AMENDMENT NO. 6 ("AMENDMENT"), dated as of May 21, 2001, to the Amended
and Restated Credit Agreement, dated as of March 10, 2000 (as the same may be
amended, restated, supplemented and/or modified from time to time in accordance
with its terms, the "CREDIT AGREEMENT"), by and between VIASOURCE
COMMUNICATIONS, INC. (the "BORROWER") and GENERAL ELECTRIC CAPITAL CORPORATION
(the "LENDER"). All capitalized terms used herein and not otherwise defined
shall have the meanings assigned to such terms in the Credit Agreement.

         The Borrower has requested that Lender amend certain margins, amend
certain financial covenants and waive compliance with certain financial
covenants and Lender is willing to grant such requests on the terms and
conditions set forth herein.

         Accordingly, the parties hereto agree as follows:

         Section 1. WAIVER. Effective as of the Effective Date (as defined
herein) until January 1, 2002, the Lender hereby waives compliance by the
Borrower with the provisions of Sections 6.7(a), 6.7(b), 6.7(c) and 6.7(d) of
the Credit Agreement.

         Section 2. AMENDMENTS. Effective as of the Effective Date (as defined
herein) the Credit Agreement is hereby amended as follows:

         (a) Section 1.1 of the Credit Agreement is hereby amended by adding the
following new defined term:

                  "CASH REVENUES" with respect to the Borrower and its
         Subsidiaries on a consolidated basis, means the amount indicated on the
         monthly financial statements, as required under subsection 5.1(i), of
         the Borrower and subsidiaries as "revenues"; excluding from such figure
         the effect from the recognition of deferred revenues thereon.

         (b) Section 2.1(c) of the Credit Agreement is hereby amended by (x)
deleting the phrase "Lender agrees to make advances available to the Borrower"
appearing on the third line thereof, and (y) substituting therefor the phrase

to the Borrower".

         (c) Section 2.2(a) of the Credit Agreement is hereby amended by (x)
deleting the tables for calculation of "Applicable Margin" for Term Loans and
Revolving Loans and (y) inserting the following substitution therefor:

                  The "APPLICABLE MARGIN" for Loans that are Base Rate Loans and
         LIBOR Rate Loans shall be determined quarterly, based upon the
         calculation of the Total Leverage Ratio for the prior fiscal quarter,
         as follows:
