                      FIFTH AMENDMENT TO CREDIT AGREEMENT
                      -----------------------------------


     This Fifth Amendment to Credit Agreement ("Amendment"), dated September 27,
2000, is entered into by and among PNC Bank, National Association ("Bank"), RMH
Teleservices, Inc. ("Borrower"), and RMH Teleservices International, Inc.
("Surety").

                                  BACKGROUND
                                  ----------

     A.   Borrower and Bank are parties to a certain letter agreement, dated
March 21, 1997 (as amended, supplemented, replaced, restated or otherwise
modified from time to time, "Credit Agreement"), pursuant to which Bank
established for the benefit of Borrower a line of credit in the maximum
aggregate principal amount of Fifteen Million Dollars ($15,000,000).
Capitalized terms used but not otherwise defined in this Amendment shall have
the meanings given to such terms in the Credit Agreement.

     B.   Bank and Borrower desire to modify the terms and conditions of the
Credit Agreement as more fully set forth herein.

TERMS AND CONDITIONS
--------------------

     NOW, THEREFORE, with the foregoing Background hereinafter incorporated by
reference, the parties hereto, intending to be legally bound, hereby covenant
and agree as follows:

     1.   Line of Credit and Use of Proceeds.  Effective on the Effective Date
          ----------------------------------
(as defined below), the Credit Agreement is hereby amended by deleting Section 1
in its entirety and replacing it with the following:

          1.   Line of Credit and Use of Proceeds.  The first credit facility is
               ----------------------------------
          a committed revolving line of credit under which Borrower may request
          and Bank, subject to the terms and conditions of this letter, will
          make advances to Borrower from time to time until the Expiration Date
          ("Line of Credit").  The aggregate principal amount of unpaid advances
          (including unreimbursed draws on Letters of Credit) shall not, at any
          time, exceed Twenty Million Dollars ($20,000,000).  The "Expiration
          Date" means September 30, 2001, or such later date as may be
          designated by Bank by written notice to Borrower.  Advances may be
          used for working capital or other general business purposed of
          Borrower.  Notwithstanding anything in the Credit Agreement to the
          contrary, in no event may the face amount of all issued and
          outstanding Letters of Credit, plus the amount of all drawn but
          unreimbursed Letters of Credit, exceed at any time Four Million
          Dollars ($4,000,000)

     2.   Base Rate Option:  Effective on the Effective Date, the Credit
          ----------------
Agreement is hereby amended by deleting Subsection 2(i) in its entirety and
replacing it with the following:
<PAGE>

          i.   Base Rate Option.  A rate of interest per annum (computed on the
               ----------------
          basis of a year of 360 days and the actual number of days elapsed)
          equal to rate of interest announced from time to time by Bank at its
          principal office as its prime rate, which rate may not be the lowest
          interest rate then being charged commercial borrowers by Bank (the
          "Prime Rate") minus one percent (1.0%).  If and when the Prime Rate
                        -----
          changes, the rate of interest on the principal of the Line of Credit
          bearing interest under the Base Rate Option will change automatically
          without notice to Borrower, effective on the date of any such change.

     3.   Euro-Rate Interest Period.  Effective on the Effective Date, the
          -------------------------
definition of "Euro-Rate Interest Period" contained in the Credit Agreement is
hereby restated in its entirety and shall read as follows:

          "Euro-Rate Interest Period" shall mean the period seven days, fourteen
          ---------------------------
          days, one, two, three, four or six months, or an overnight period,
          each as selected by Borrower commencing on the date on which a Euro-
          Rate Option is elected to commence; provided, that if a Euro-Rate
                                              --------
          Interest Period would end on a day which is not a Business Day, it
          shall end on the next succeeding Business day, unless, with respect to
          Euro-Rate Interest Periods of one month or longer, such day falls in
          the succeeding calendar month on which case the Euro-Rate Interest
          Period shall end on the next preceding Business Day.  In no event
          shall any Euro-Rate Interest Period end on a day after the Expiration
          Date.

     4.   Negative Covenants:  Effective on the Effective Date, the Credit
          ------------------
Agreement is hereby amended by deleting Subsections III (d) and III(f) of
Exhibit "A" in their entirety and replacing them with the following:

          (d)  Borrower will not, nor suffer or permit any Subsidiary to, make
          acquisitions of all or substantially all of the property or assets of

          investment on terms and conditions satisfactory to Bank of an
          aggregate amount not to exceed $1,500,000 in a joint venture with
          Advanta Partners to be called "365biz.com."

          (f)  Subject to Subsection (a) above, Borrower and each of its
          Subsidiaries will not incur, create or assume any commitment to make
          any direct or indirect payment, whether rent or otherwise, under any
          lease rental or other arrangement for the use of real or personal
          property, except for: (i) operating leases with Bank or its
          affiliates, or (ii) operating leases with other parties so long as the
          aggregate outstanding obligations, direct or indirect, due or to
          become due, under all such leases does not exceed $16,000,000.
