a Prime Rate Loan.

           (b)  Revolving Credit Loans shall be made ratably by the Lenders in
accordance with their respective Revolving Credit Commitments; provided,
however, that the failure of any Lender to make any Revolving Credit Loan shall
not in itself relieve any other Lender of its obligation to lend hereunder.

           (c)  Each Revolving Credit Loan shall be either a Prime Rate Loan or
a LIBOR Rate Loan as the Borrower may request pursuant to Section 2.5 hereof.
Loans of more than one type and Interest Period may be outstanding at the same
time.

           (d)  Each Lender shall make its Revolving Credit Loans on the
proposed dates thereof by paying the amount required to the Administrative Agent
in Philadelphia, Pennsylvania in immediately available funds not later than
12:00 noon, Philadelphia time, and the Administrative Agent shall as soon as
practicable, but in no event later than 3:00 p.m., Philadelphia time, credit the
amounts so received to the general deposit account of the Borrower with the
Administrative Agent in immediately available funds or, if Revolving Credit
Loans are not to be made on such date because any condition precedent to a
borrowing herein specified is not met, return the amounts so received to the
respective Lenders.

     2.2.1 Swing Loans. (a) Subject to the terms and conditions set forth
           -----------
herein, the Swing Bank agrees to make Swing Loans to the Borrower, in the Swing
Bank's sole discretion, from time to time during the Commitment Period, in an
aggregate principal amount at any time outstanding that will not result in the
aggregate principal amount of outstanding Swing Loans exceeding $3,000,000.00.
Within the foregoing limit and subject to the Swing Bank's discretion and the
terms and conditions set forth herein, the Borrower may borrow, prepay and
reborrow the Swing Loans. Each Swing Loan shall be made as a Prime Rate Loan.

           (b)  To request a Swing Loan, the Borrower shall notify the Swing
Bank (which shall promptly notify the Administrative Agent) of such request by
telephone (confirmed by telecopy), not later than 1:00 p.m., Philadelphia time,
on the day of a proposed

                                      -11-
<PAGE>

Swing Loan. Each such notice shall be irrevocable and shall specify the
requested date (which shall be a Business Day) of the requested Swing Loan and
the amount of the requested Swing Loan. The Swing Bank shall make each Swing
Loan available to the Borrower, in its discretion, by means of a credit to the
general deposit account of the Borrower with the Administrative Agent by 3:00
p.m., Philadelphia time, on the requested date of such Swing Loan.

          (c)  The Swing Bank may by written notice given to the Administrative
Agent not later than 12:00 noon, Philadelphia Time, on any Business Day require
the Lenders to acquire participations on such Business Day in all or a portion
of the Swing Loans outstanding, together with interest accrued thereon. Such
notice shall specify the aggregate amount of Swing Loans in which Lenders will
participate. Promptly upon receipt of such notice, the Administrative Agent will
give notice thereof to each Lender, specifying in such notice such Lender's pro
rata share of such Swing Loan or Loans, together with interest accrued thereon,
which pro rata share shall be based upon the proportion that such Lender's
Revolving Credit Commitment bears to the Total Revolving Credit Commitment. Each
Lender hereby absolutely and unconditionally agrees, upon receipt of notice as
provided above, to pay to the Administrative Agent, for the account of the Swing
Bank, such Lender's pro rata share of such Swing Loan or Loans. Each Lender
acknowledges and agrees that its obligation to acquire participations in Swing
Loans pursuant to this paragraph is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including the occurrence and
continuance of a Default or Event of Default or reduction or termination of the
Revolving Credit Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever. Each Lender shall
comply with its obligation under this paragraph in the same manner as provided
in Section 2.2(d) with respect to Revolving Credit Loans made by such Lender and
the Administrative Agent shall promptly pay to the Swing Bank the amounts so
received by it from the Lenders. The Administrative Agent shall notify the
Borrower of any participations in any Swing Loan acquired pursuant to this
paragraph, and thereafter payments in respect of such Swing Loan shall be made
to the Administrative Agent and not to the Swing Bank. Any amounts received by
the Swing Bank from the Borrower (or other party on behalf of the applicable
Borrower) in respect of a Swing Loan after receipt by the Swing Bank of the
proceeds of a sale of participations therein shall be promptly remitted to the
Administrative Agent; any such amounts received by the Administrative Agent
shall be promptly remitted by the Administrative Agent to the Lender that shall
have made their payments pursuant to this paragraph and to the Swing Bank, as

                                      -12-
<PAGE>

their interests may appear. The purchase of participations in a Swing Loan
pursuant to this paragraph shall not relieve the Borrower of any default in the
payment thereof.

          (d) The Swing Loans made by the Swing Bank on any date shall be in a
minimum amount of $250,000.00 and in integral multiples of $100,000.00.

     2.3  Notes.  (a) The Revolving Credit Loans made by the Lenders pursuant to
          -----
Section 2.2 hereof shall be evidenced by promissory notes of the Borrower
substantially in the form of Exhibit "A" hereto with appropriate insertions
(individually, a "Revolving Credit Note" and, collectively, the "Revolving
Credit Notes"), payable to the order of each Lender and representing the
obligations of the Borrower to pay to each Lender on the Termination Date the
lesser of (y) the amount of each Lender's Revolving Credit Commitment or (z) the
aggregate unpaid principal amount of all Revolving Credit Loans made by such
Lender, with interest thereon as hereinafter prescribed in Section 2.4 hereof.

          (b) The Swing Loans made by the Swing Bank pursuant to Section 2.2.1
hereof shall be evidenced by a promissory note of the Borrower payable to the
order of the Swing Bank and representing the obligations of the Borrower to pay
to the Swing Bank on the Termination Date the lesser of (y) $3,000,000.00 or (z)
the aggregate unpaid principal amount of all Swing Loans made by the Swing Loan
Bank, with interest thereon as hereafter prescribed in Section 2.4 hereof.

          (c) The date and amount of each Loan, the basis for calculating
interest, the Interest Period applicable thereto and each payment of principal
with respect thereto shall be endorsed by the Lenders on the schedule annexed to
and constituting a part of the Notes.  The aggregate unpaid amount of Loans set
forth on such schedule shall be presumed to be the principal amount owing and
unpaid thereon.  The failure of a Lender to make such endorsement on such
schedule shall not prejudice such Lender in any way, nor affect its rights
hereunder with respect to any Revolving Credit Loan.  The Notes shall be dated
the date of this Agreement and be stated to mature on the Termination Date.

     2.4  Interest.  Interest on each Revolving Credit Loan shall be at a per
          --------
annum rate to be elected by the Borrower, in accordance with Section 2.5 hereof,
and shall be one of the following:

          (a) a fluctuating rate equal to the Prime Rate, which interest rate

<PAGE>

          (b) subject to availability, the LIBOR Rate for Interest Periods
selected by the Borrower plus the applicable Margin.

The Administrative Agent shall determine each interest rate applicable to the
Revolving Credit Loans and shall promptly advise the Borrower and the Lenders of
the interest rate so determined.  Each Swing Loan shall be Prime Rate Loan.
Interest on each Prime Rate Loan, except Swing Loans, shall be payable monthly
in arrears to the Administrative Agent for the pro rata benefit of the Lenders
on the first Business Day of each month, commencing on the first such day to
occur after the pertinent loan is made and upon payment in full thereof.
Interest on Swing Loans shall be payable on such dates as set forth above to the
Swing Bank. Interest on each LIBOR Rate Loan shall be payable to the
Administrative Agent for the pro rata benefit of the Lenders in arrears (i) in
the case of Revolving Credit Loans with Interest Periods of three months or
less, at the end of each applicable Interest Period and (ii) in the case of
Revolving Credit Loans with Interest Periods of more than three months, at the
end of each calendar quarter and at the end of the Interest Period.  Whenever
the unpaid principal balance of any Loan shall become due and payable (whether
at the stated maturity thereof, by acceleration or otherwise) interest shall
thereafter be payable on demand to the Administrative Agent for the pro rata
benefit of the Lenders at the Involuntary Rate; provided, however, that no
interest payable hereunder shall be in excess of the rate permitted by
applicable law.  Interest on each Loan shall be calculated on the basis of a
year of 360 days for the actual number of days elapsed.

     2.5  Procedure for Revolving Credit Borrowing.  The Borrower may borrow
          ----------------------------------------

Credit Loan requested, the date thereof, whether it is to be a LIBOR Rate Loan
or a Prime Rate Loan and, if it is to be a LIBOR Rate Loan, the duration of the
Interest Period applicable thereto.  Requests for LIBOR Rate Loans shall be

Credit Loan may be written or oral, but if oral, it shall be confirmed in

Days thereafter.  The Administrative Agent shall

                                      -14-

     2.6   Conversion and Renewals.  The Borrower may elect from time to time to
           -----------------------
convert all or a part of one type of Revolving Credit Loan into another type of
Revolving Credit Loan or to renew all or part of a Revolving Credit Loan by
giving the Administrative Agent notice at least one (1) Business Day before the
conversion into a Prime Rate Loan and at least three (3) Business Days before
the conversion into or renewal of a LIBOR Rate Loan, specifying:  (1) the
renewal or conversion date; (2) the amount of the Revolving Credit Loan to be
converted or renewed; (3) in the case of conversions, the type of Revolving
Credit Loan to be converted into; and (4) in the case of renewals of or a
conversion into LIBOR Rate Loans, the duration of the Interest Period applicable
thereto; provided that (a) the minimum principal amount of each Revolving Credit
Loan outstanding after a renewal or conversion to a LIBOR Rate Loan shall be
$500,000.00 or to a Prime Rate Loan shall be $250,000.00; and (b) LIBOR Rate
Loans can be converted only on the last day of the Interest Period of such Loan.

the number of Business Days specified above for such notice.  Any request for a
conversion or a renewal under this Section 2.6 may be written or oral, but if

Administrative Agent within two (2) Business Days thereafter.  If the Borrower
shall fail to give the Administrative Agent the notice as specified above for
the renewal or conversion of a LIBOR Rate Loan prior to the end of the Interest
Period with respect thereto, such LIBOR Rate Loan shall automatically be
converted into a Prime Rate Loan on the last day of the Interest Period for such
Revolving Credit Loan.  The Administrative Agent shall promptly advise (but in
any event, by 2:00 p.m. Philadelphia time, two (2) Business Days prior to a
LIBOR Rate Loan or by 11:00 a.m. on the same Business Day in the case of a Prime

           ------------------------------

          (a) Disaster.  Notwithstanding anything contained in this Agreement to
              --------
the contrary, if the Administrative Agent determines that:

based upon a LIBOR Rate, or

               (ii) the LIBOR Rate does not accurately reflect the cost to a
Lender of making or maintaining a LIBOR Rate Loan then the Administrative Agent
shall give the Borrower prompt notice thereof, and so long as such condition
shall remain in effect the right of the Borrower to select a LIBOR Rate Loan or
to convert a Prime Rate Loan into a LIBOR Rate Loan shall be suspended. The
Borrower, in such event, shall, on the last day of a then current Interest
Period either prepay such loan together with accrued interest thereon or convert
such loan into a Prime Rate Loan.

          (b) Illegality.  Notwithstanding any other provisions herein, if any
              ----------
Requirements of Law, regulation, order or decree or any change therein or in the
interpretation or application thereof shall make it unlawful for a Lender to
make or maintain LIBOR Rate Loans as contemplated by this Agreement, the
Commitment hereunder to make LIBOR Rate Loans shall forthwith be canceled with
respect to such Lender upon notice to the Administrative Agent and the Borrower
and Revolving Credit Loans then outstanding as LIBOR Rate Loans, if any, shall,
at the option of the Borrower, be prepaid in full together with all interest
accrued and unpaid to the date of any such prepayment together with any amounts
required by Section 2.10 hereof, or converted into a Prime Rate Loan.

Commitment, the Borrower agrees to pay the Administrative Agent for the pro rata
benefit of the Lenders a commitment fee for the Commitment Period based on the
average daily unused portion of the Total Revolving Credit Commitments and the
applicable Leverage Ratio and Liabilities to Tangible Net Worth Ratio as
reflected in the financial statements delivered pursuant to Section 5.1 hereof
in the percentage per annum as determined by reference to the grid set forth

     Any fee payable under this Section 2.9 which is not paid when due shall
bear interest at the Involuntary Rate until paid, payable on demand.  Such fee
shall be computed on the basis of a 360 day year for the actual days elapsed and
shall be payable monthly on the first day of each month during the Commitment
Period and on the Termination Date.  The "unused portion of the Total Revolving
Credit Commitments" means, at any time, the Total Revolving Credit Commitments
less the sum of (a) the unpaid principal balance of all Revolving Credit Loans,
(b) Letter of Credit Exposure and (c) Acceptance Draft Exposure.  Upon
termination or reduction of the Revolving Credit Commitments, the Borrower will
pay to the Administrative Agent, for the pro rata account of the Lenders,
accrued unused fees on the portion of the Revolving Credit Commitment terminated
or reduced to the date of termination or reduction.

     2.10  Additional Compensation in Certain Circumstances.

          (a) Increased Costs or Reduced Return Resulting From Taxes, Reserves,
              -----------------------------------------------------------------
Capital Adequacy Requirements, Expenses, Etc.  If any law or guideline or
---------------------------------------------
interpretation or application thereof by any Governmental Authority charged with
the interpretation or administration thereof or compliance with any request or
directive of any

                                      -17-
<PAGE>

Governmental Authority (whether or not having the force of law) now existing or
hereafter adopted:

          (i)   subjects the Administrative Agent or a Lender to any tax or
changes the basis of taxation with respect to this Agreement, the Notes, the
Loans or payments by the Borrower of principal, interest, commitment fee or
other amounts due from the Borrower hereunder or under the Notes (except for
taxes on the overall net income of the Administrative Agent or a Lender imposed
by the jurisdiction in which the Administrative Agent or such Lender's principal
office is located),

          (ii)  imposes, modifies or deems applicable any reserve, special
deposit or similar requirement against credits or commitments to extend credit
extended by, assets (funded or contingent) of, deposits with or for the account
of, or other acquisition of funds by, the Administrative Agent or a Lender (or
participation therein) (other than requirements expressly included herein in the
determination of the LIBOR Rate hereunder),

          (iii) imposes, modifies or deems applicable any capital adequacy or
similar requirement (A) against assets (funded or contingent) of, or credits or
commitments to extend credit extended by, the Administrative Agent or a Lender
(or participations therein) or (B) otherwise applicable to the obligations of
the Administrative Agent or a Lender under this Agreement, or

          (iv)  imposes upon the Administrative Agent or a Lender any other
condition or expense with respect to this Agreement, the Notes or its making,
maintenance or funding any part of the Loans (or participations therein), and
the result of any of the foregoing is to increase the cost to, reduce the income
receivable by, or impose any expense (including loss of margin) upon the
Administrative Agent or a Lender with respect to this Agreement, the Notes or
the making, maintenance or funding of any part of the Loans (or, in the case of
any capital adequacy or similar requirement, to have the effect of reducing the
rate of return on the Administrative Agent's or a Lender's capital, taking into
consideration the Administrative Agent's and such Lender's policies with respect
to capital adequacy) by an amount which the Administrative Agent or a Lender
deems to be material, the Administrative Agent or Lender shall from time to time
notify the Borrower of the amount determined in good faith (using any averaging
and attribution methods) by the Administrative Agent or Lender (which
determination shall be conclusive) to be necessary to compensate the
Administrative Agent or Lender for such increase, reduction or imposition.  Such
amount shall be due and

                                      -18-
<PAGE>

payable by the Borrower to the Administrative Agent or Lender ten (10) ten
Business Days after such notice is given. A certificate by the Administrative
Agent or Lender as to the amount due and payable under this Section 2.10(a) from
time to time and the method of calculating such amount shall be conclusive
absent manifest error.

          All references to "Lender" shall be deemed to include any participant
in such Lender's Revolving Credit Commitment.

          (b) Indemnity.  In addition to the compensation required by subsection
              ---------
(a) of this Section 2.10, the Borrower shall indemnify the Administrative Agent
and a Lender against any loss or expense (including loss of margin) which the
Administrative Agent or Lender has sustained or incurred as a consequence of any

          (i)   payment, prepayment or conversion of any part of any LIBOR Rate
Loan on a day other than the last day of the applicable Interest Period (whether
or not such payment, prepayment or conversion is mandatory or automatic and
whether or not such payment or prepayment is then due).

          (ii)  attempt by the Borrower to revoke (expressly, by later
inconsistent notices or otherwise) in whole or part any notice stated herein to
be irrevocable (the Administrative Agent having in its sole discretion the
options (A) to give effect to such attempted revocation and obtain indemnity
under this Section 2.10(b) or (B) to treat such attempted revocation as having
no force or effect, as if never made), or

          (iii) default by the Borrower in the performance or observance of any
covenant or condition contained in this Agreement or the Notes, including
without limitation any failure of the Borrower to pay when due (by acceleration
or otherwise) any principal, interest, commitment fee or any other amount due
hereunder or under a Note.

If the Administrative Agent or Lender sustains or incurs any such loss or
expense it shall from time to time notify the Borrower of the amount determined
in good faith by the Administrative Agent or Lender (which determination shall
be conclusive) to be necessary to indemnify the Administrative Agent or Lender
for such loss or expense.  Such amount shall be due and payable by the Borrower
to the Administrative Agent or Lender ten (10) Business Days after such notice
is given.

          All references to "Lender" shall be deemed to include any participant
in such Lender's Revolving Credit Commitment.

                                      -19-
<PAGE>

          The indemnities set forth herein shall survive payment in full of all
LIBOR Rate Loans and all other Revolving Credit Loans made pursuant to this
Agreement.

     2.11  Termination or Reduction of Commitment.  Subject to the indemnity
           --------------------------------------
agreement with respect to LIBOR Rate Loans set forth in Section 2.10(b) hereof,
the Borrower shall have the right, upon not less than three (3) Business Days'
irrevocable notice to the Administrative Agent, to terminate the Total Revolving
Credit Commitment or, from time to time, to reduce the amount of the Total
Revolving Credit Commitment, provided that (a) any such reduction (i) shall be
in the minimum amount of $1,000,000 or a multiple thereof, (ii) shall reduce
permanently the amount of the Total Revolving Credit Commitment then in effect,
and (iii) shall be accompanied by prepayment of the Revolving Credit Loans
outstanding, together with accrued interest on the amount so prepaid to the
dates of each such prepayment, to the extent, if any, that the Revolving Credit
Loans then outstanding exceed the amount of the Total Revolving Credit
Commitment as then reduced, and (b) any such termination of the Total Revolving
Credit Commitment shall be accompanied by prepayment in full of the Revolving
Credit Loans outstanding, together with accrued interest thereon to the date of
prepayment, and the payment of any unpaid commitment fee then accrued hereunder.

     2.12  Prepayment.  Subject to the indemnity agreement with respect to
           ----------
LIBOR Rate Loans set forth in Section 2.10(b) hereof, the Borrower may prepay
any Loan in whole or in part without premium or penalty together with interest
accrued on the amount prepaid to the date of prepayment. Prepayments of Loans
may be reborrowed on a revolving basis as aforesaid.

     2.13  Payments. (a)  Except as set forth below with respect to Swing Loans,
           --------
all payments (including prepayments) to be made by the Borrower on account of
principal, interest and fees shall be made without setoff or counterclaim and
shall be made to the Lender on the date of payment at the office of the
Administrative Agent set forth in Section 10.1 hereof or at such other place as
the Administrative Agent may from time to time designate in writing on or before
11:00 a.m. (Philadelphia time).  All such payments with respect to Swing Loans
shall be to the Swing Bank.  In each case in lawful money of the United States
of America and in immediately available funds.  If any payment hereunder (other
than payments on LIBOR Rate Loans) becomes due and payable on a day other than a
Business Day, such payment shall be extended to the next succeeding Business Day
and, with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension.  If any payment on a LIBOR

                                      -20-
<PAGE>

Rate Loan becomes due and payable on a day other than a Business Day, the
maturity thereof shall be extended to the next succeeding Business Day unless
the result of such extension would be to extend such payment into another
calendar month in which event such payment shall be made on the immediately
preceding Business Day.

            (b) The Borrower hereby authorizes the Administrative Agent to
charge any of its accounts maintained at the Administrative Agent on the date
any payment is due hereunder or under a Note.

     2.14   Pro Rata Treatment.  (a) Except for any payment, reimbursement or
            ------------------
other indemnity to any Lender or other indemnified person under Section 2.7(b),
2.10, 2.19 or 10.4 hereof, or under Section 2.4 and 2.13 with respect to Swing
Loans, each borrowing, each payment or prepayment of principal of the Revolving
Credit Notes, each payment of interest on the Revolving Credit Notes, each
payment of any fee or other amount payable hereunder and each reduction of the
Total Revolving Credit Commitment shall be made pro rata among the Lenders in
the proportions that their Revolving Credit Commitments bear to the Total
Revolving Credit Commitment.

            (b) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to the time the Lender is required to fund any
proposed borrowing that such Lender will not make the amount that would
constitute its pro rata share of the borrowing on such date available to the
Administrative Agent, the Administrative Agent may (assuming that the
Administrative Agent has furnished such Lender with notice of the proposed
borrowing as required under Section 2.5 hereof) assume that such Lender has made
such amount available to the Administrative Agent on such date, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is made available by such
Lender to the Administrative Agent on a date after such borrowing date, such
Lender shall pay to the Administrative Agent on demand an amount equal to the
product of (i) the daily average Federal funds rate during such period as quoted
by the Administrative Agent, times (ii) the amount of such Lender's pro rata
share of such borrowing, times (iii) a fraction the numerator of which is the
number of days that elapse from and including such borrowing date to the date on
which such Lender's pro rata share of such borrowing shall have become
immediately available to the Administrative Agent and the denominator of which
is 360. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this subsection shall be conclusive in the
absence of manifest error. If such Lender's

                                      -21-
<PAGE>

pro rata share of such borrowing is not in fact made available to the
Administrative Agent by such Lender within three (3) Business Days of such
borrowing date, the Administrative Agent shall be entitled to recover such
amount with interest thereon at the rate per annum applicable to the relevant
Revolving Credit Loans hereunder, on demand, from the Borrower.

          (c) Notwithstanding the foregoing provisions of this Section 2.14, in
the event that a Lender fails to make any amount that would constitute its pro
rata share of a borrowing available to the Administrative Agent, the
Administrative Agent shall so notify the other Lender(s) whereupon such
Lender(s) shall be required to make such amount available to the Administrative
Agent on a pro rata basis between (or among) the Lenders in the proportions that
their Revolving Credit Commitments bear to the Total Revolving Credit
Commitment, in an aggregate amount not to exceed the amount of such Lender's
Revolving Credit Commitment as set forth on Schedule A attached hereto.

     2.15  Sharing of Setoffs.  Each Lender agrees that if it shall, through the
           ------------------
exercise of a right of banker's lien, setoff or counterclaim against the
Borrower or a Guarantor, including, but not limited to, a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, obtain
payment (voluntary or involuntary) in respect of a Revolving Credit Note held by
it or participation in a Swing Loan Note as a result of which the unpaid
principal portion of the Revolving Credit Notes held by it or participation in a
Swing Loan Note shall be proportionately less than the unpaid principal portion
of the Revolving Credit Notes or participation in a Swing Loan Note held by any
other Lender, it shall be deemed to have simultaneously purchased from such
other Lender a participation in the Revolving Credit Notes or Swing Loan Note
held by such other Lender with the purchase price payable in cash upon demand by
such other Lender, so that the aggregate unpaid principal amount of the
Revolving Credit Notes and participations in Revolving Credit Notes and Swing
Loan Note held by it shall be in the same proportion to the aggregate unpaid
principal amount of all Revolving Credit Notes and Swing Loan Note then
outstanding as the principal amount of the Revolving Credit Notes and Swing Loan
Note held by it prior to such exercise of banker's lien, setoff or counterclaim
was to the principal amount of all Revolving Credit Notes and Swing Loan Note
outstanding prior to such exercise of banker's lien, setoff or counterclaim;
provided, however, that if any such purchase or purchases or adjustments shall
be made pursuant to this Section 2.15 and such other Lender shall thereafter
receive or recover

                                      -22-
<PAGE>

from or respecting the Borrower or any Guarantor any amount in respect of a
Revolving Credit Note or Swing Loan Note proportionally greater than that
received by the first Lender, such purchase or purchases or adjustments shall be
repurchased and rescinded to the extent of such receipt or recovery and the
purchase price or prices paid or adjustments made shall be repaid or restored,
as applicable, without interest; provided, that, if such disproportionate amount
received or recovered by such other Lender exceeds the amount necessary to
restore the Lenders respective pro rata shares, then this section shall apply to
such excess. The Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Note deemed to have been so
purchased may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by the Borrower to such
Lender as fully as if such Lender held a Note in the amount of such
participation.

     2.16  Use of Proceeds.  The Borrower will utilize the proceeds of the
           ---------------
initial Revolving Credit Loans to repay any amounts owing to Mellon, EAB and
HSBC under the revolving credit agreement among Mellon, as Administrative Agent
and a Lender, EAB, HSBC and the Borrower dated October 28, 1999 (the "Prior
Agreement").  Any remaining proceeds of the initial borrowing and of any
subsequent Loans may be used by the Borrower for working capital purposes,
capital expenditures and to fund the purchase price of Permitted Acquisitions
provided no portion of the proceeds of any Loan shall be used by the Borrower in
any manner which might cause the borrowing or the application of such proceeds
to violate Regulation G, Regulation U, Regulation T or Regulation X of the Board
of Governors of the Federal Reserve System.

     2.17  Issuance of Letters of Credit.  Upon the request of the Borrower, and
           -----------------------------
subject to the conditions set forth herein and such other conditions to the
opening of Letters of Credit as the Administrative Agent requires of its
customers generally, the Administrative Agent shall from time to time issue
documentary or standby letters of credit (each, a "Letter of Credit") for the
account of the Borrower.  The issuance of each Letter of Credit shall be made on
at least one (1) Business Day's prior written notice from the Borrower to the
Administrative Agent which written notice shall be an application for a Letter
of Credit on the Administrative Agent's customary form.  The expiration date of
any Letter of Credit shall not be later than one (1) year from the date of
issuance thereof nor, in any event, later than the Termination Date.  The
Letters of Credit shall be issued in respect of any transactions occurring in
the Borrower's ordinary course of business.

                                      -23-
<PAGE>

     2.18  Actions of Administrative Agent.  Any Letter of Credit may, in the
           -------------------------------
discretion of the Administrative Agent or its correspondents, be interpreted by
them (to the extent not inconsistent with such Letter of Credit) in accordance
with the Uniform Customs and Practice for Documentary Credits of the
International Chamber of Commerce, as adopted or amended from time to time, or
any other rules, regulations and customs prevailing at the place where any
Letter of Credit is available or the drafts are drawn or negotiated.  The
Administrative Agent and its correspondents may in good faith accept and act
upon the name, signature, or act of any party purporting to be the executor,
administrator, receiver, trustee in bankruptcy, or other legal representative of
any party designated in any Letter of Credit in the place of the name,
signature, or act of such party.

     2.19  Indemnity as to Letters of Credit.  The Borrower hereby agrees to
           ---------------------------------
indemnify and hold harmless the Administrative Agent and the Lenders from and
against any and all claims, damages, losses, liabilities, costs or expenses
whatsoever which the Administrative Agent or the Lenders may incur or suffer by
reason of or in connection with the execution and delivery or assignment of, or
payment under, any Letter of Credit, except only if and to the extent that any
such claim, damage, loss, liability, cost or expense shall be caused by the
willful misconduct or gross negligence of the Administrative Agent or any Lender
performing its obligations respecting such Letter of Credit under this
Agreement.  Without limiting the foregoing, the Borrower further agrees to
indemnify and hold harmless the Administrative Agent, its officers and
directors, each person who controls the Administrative Agent within the meaning
of Section 15 of the Securities Act of 1933 or any applicable state securities
law and their respective successors and assigns from and against any and all
claims, damages, losses, liabilities, costs or expenses, joint or several, to
which they or any of them may become subject under any federal or state
securities law, rule or regulation, at common law or otherwise, insofar as such
claims, damages, losses, liabilities, costs or expenses arise out of or are
based upon the execution and delivery by the Administrative Agent of any Letters
of Credit or the execution and delivery of any other document in connection
therewith (but not including any claims, damages, losses, liabilities, costs or
expenses arising from the gross negligence or willful misconduct of the
Administrative Agent).  The Borrower upon demand by the Administrative Agent at
any time, shall reimburse the Administrative Agent for any reasonable legal or
other expenses incurred in connection with investigating or defending against
any of the foregoing.  The indemnities contained herein shall survive the
expiration or termination of the Letters of Credit and this Agreement.

                                      -24-
<PAGE>

     2.20  Letter of Credit Fees.  The Borrower agrees to pay to the
           ---------------------
Administrative Agent its standard draw fees and commissions in effect from time
to time.  The full amount of any commission in excess of $500.00 shall be shared
with the Lenders on a pro rata basis in accordance with the provisions of
Section 2.14 hereof.

     2.21  Acceptance Drafts.  (a)  Upon the terms and conditions hereof, the
           -----------------
Borrower may, from time to time from the date hereof until the Termination Date,
request the Administrative Agent to accept drafts in the form of Exhibit B (each
an "Acceptance Draft" and, collectively, the "Acceptance Drafts"), at the
Borrower's election.

           (b)  The Borrower shall give the Administrative Agent telephonic
notice (immediately confirmed in writing) of its request that the Administrative
Agent accept such Acceptance Draft no later than 1:00 p.m. (Philadelphia time)
on the same day of such request (the "Acceptance Date"). Such notice shall
contain the aggregate face amount (which shall be in minimum aggregate principal
amounts of $1,000,000 and in integral multiples of $100,000 in excess thereof)
and maturity date of such Acceptance Draft, which maturity date shall not be
later than the earlier of (a) 30, 60, 90 or 120 days after the Acceptance Date
of such Acceptance Draft, as the Borrower shall designate, and (b) the
Termination Date. Such notices also shall describe the underlying goods and
indicate their origin and destination points or provide other evidence of the
underlying transaction in form and substance as may be acceptable to the
Administrative Agent to permit it to accurately complete the appropriate
eligibility legend (i.e., "eligibility certificate") on the face of the
Acceptance Draft. The Borrower shall promptly confirm such telephonic notices by
telecopy and mailing an original signed notice. Each draft shall mature on a
Business Day, which shall be at least thirty (30) days after the Acceptance
Date. No Acceptance Draft shall be dated or accepted more than thirty (30) days
before or more than thirty (30) days after the date of the shipment of goods to
which it relates. The Borrower hereby irrevocably authorizes the Administrative
Agent to complete its Acceptance Draft in accordance with the instructions given
pursuant to this Section 2.21. Any pre-signed drafts held by the Administrative
Agent for completion shall not be affected by the departure of the signer as an
authorized signatory of the Borrower, which drafts shall nevertheless remain
valid and binding upon the Borrower for all purposes as if the signer's
authority had continued in effect. (Such completion and presentment, however,
shall not obligate the Administrative Agent to accept any such Acceptance
Draft.)

                                      -25-
<PAGE>

          (c) Upon receipt of such notices from the Borrower, the Administrative
Agent shall promptly notify each Lender of (i) its pro rata (based on its
Revolving Credit Commitment) share of such Acceptance Draft, (ii) the maturity
date of such Acceptance Draft and (iii) the discount rate and commission
applicable to such Acceptance Draft. The Administrative Agent may decline to
create any such Acceptance Draft if the Administrative Agent is not then
providing such financing to its middle market customers with credit standings
similar to the Borrower's.

          (d) The Administrative Agent in its discretion at any time or from
time to time may sell, rediscount or otherwise dispose of any Acceptance Draft
without any notice or credit to or consent from the Borrower or any other
Lender.

          (e) Each Acceptance Draft shall relate to one or more specific
transactions involving the importation or exportation of goods or the domestic
shipment of goods within the United States. The goods relating to each
Acceptance Draft shall have a c.i.f. value equaling or exceeding the amount of
the Acceptance Draft, shall be of good and merchantable quality, shall be fully
insured in accordance with prudent industry practice and shall not be the
subject of any security interest granted by the Borrower or any Subsidiary. No
other source shall have financed the transaction underlying the Acceptance
Draft. The Borrower shall have procured all import, export and other licenses
essential to the underlying transaction and shall have complied with all
applicable laws pertaining to the underlying goods and transaction. Each
Acceptance Draft shall qualify (upon acceptance) in all respects with the
requirements for eligibility for discount of the Federal Reserve Lenders of the
United States. With regard to each Acceptance Draft presented, the Borrower
represents and warrants to the Administrative Agent and the Lenders that, as of
the date of presentment, the Acceptance Draft and underlying goods and
transaction conform to the requirements of this subsection, and the Borrower
covenants and agrees that they will continue to conform to those requirements
for so long as the Acceptance Draft is outstanding.

     2.22  Payment in Respect of Letters of Credit and Acceptances;
           --------------------------------------------------------
Reimbursement. Upon the issuance of any Letter of Credit, the Administrative
-------------
Agent shall notify each Lender of the principal amount, the number, and the
expiration date thereof and the amount of such Lender's participation therein.
By the issuance of a Letter of Credit hereunder and without further action on
the part of the Administrative Agent or the Lenders, each Lender hereby accepts
from the Administrative Agent a participation (which participation shall be
nonrecourse to the Administrative Agent)

                                      -26-
<PAGE>

in such Letter of Credit equal to such Lender's pro rata (based on its Revolving
Credit Commitment) share of such Letter of Credit, effective upon the issuance
of such Letter of Credit. The Administrative Agent shall notify each Lender of
the presentment to the Administrative Agent of any draft for acceptance
hereunder, which notice shall include the amount of such draft and the maturity
date thereof. Upon the acceptance of any Acceptance Draft, the Administrative
Agent shall: (i) notify each Lender of the net proceeds thereof and the amount
of such Lenders's participation therein (acquired pursuant to the terms hereof)
and (ii) credit the net proceeds thereof to the Borrower's account maintained
with the Administrative Agent for such purpose. Such net proceeds shall be in an
amount equal to the face amount of such Acceptance Draft less the applicable
discount and commission. The funds, net of such discounts and commissions, so
credited to the Borrower's account shall be immediately available to the
Borrower, and the Administrative Agent shall promptly notify the Borrower as to
the amount of the net funds so credited. By acceptance of an Acceptance Draft
and without further action on the part of the Administrative Agent or the
Lenders, each Lender hereby accepts from the Administrative Agent a
participation (which participation shall be nonrecourse to the Administrative
Agent) in such Acceptance Draft equal to such Lender's pro rata (based on its
Revolving Credit Commitment) share of such Acceptance Draft, effective upon the
issuance of such Acceptance Draft. Each Lender hereby absolutely and
unconditionally assumes, as primary obligor and not as a surety, and agrees to
pay and discharge, and to indemnify and hold the Administrative Agent harmless
from liability in respect of, such Lender's pro rata share of the amount of any
drawing under a Letter of Credit and payment of any Acceptance Draft. Each
Lender acknowledges and agrees that its obligation to acquire participation in
each Letter of Credit issued by and each Acceptance Draft accepted by the
Administrative Agent and its obligation to make the payments specified herein,
and the right of the Administrative Agent to receive the same, in the manner
specified herein, are absolute and unconditional and shall not be affected by
any circumstance whatsoever, including, without limitation, the occurrence and
continuance of a Default or an Event of Default hereunder, and that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever. The Administrative Agent shall review, on behalf of the Lenders,
each draft presented under a Letter of Credit and shall notify each Lender of
any such presentment. Promptly after it shall have ascertained that any draft
presented under such Letter of Credit appears on its face to be in substantial
conformity with the terms and conditions of the Letter of Credit, the
Administrative Agent shall give telephonic or facsimile notice to the Lenders
and the Borrower of the receipt and amount

                                      -27-

of such draft and the date on which payment thereon will be made. The Borrower
shall reimburse the Administrative Agent for the amount specified in such notice
by no later than 11:00 a.m. (Philadelphia time) on the date such payment is
scheduled to be made. If the Borrower has not so discharged such reimbursement
obligations and the Administrative Agent is unable to recover the required
amount by debiting the Borrower's account (as hereinafter provided), the
Administrative Agent shall give each Lender notice of any amount that remains
unreimbursed, and each Lender shall promptly, but in any event within two hours
of the receipt of such notice, pay the amounts required to the Administrative
Agent in immediately available funds, and the Administrative Agent, not later
than 3:00 p.m. (Philadelphia time) on such day, shall make the appropriate
payment to the beneficiary. If the Lenders shall pay any draft presented under a
Letter of Credit or make any such payment upon the maturity of an Acceptance
Draft, then the Administrative Agent, on behalf of the Lenders, shall charge the
general deposit account of the Borrower with the Administrative Agent for the
amount thereof, together with the Administrative Agent's customary overdraft or
similar fee in the event the funds available in such account shall not be
sufficient to reimburse the Lenders for such payment. If the Lenders have not
been reimbursed with respect to such drawing as provided above, the Borrower
shall pay to, the Administrative Agent, for the account of the Lenders, the
amount of the drawing together with interest on such amount at a rate per annum
(computed on the basis of the actual number of days elapsed over a year of 360
days) equal to the Involuntary Rate payable on demand. The obligations of the
Borrower under this Section 2.22 to reimburse the Lenders and the Administrative
Agent for all drawings under Letters of Credit and payments made in respect of
Acceptance Drafts shall be absolute, unconditional and irrevocable and shall be
satisfied strictly in accordance with their terms, irrespective of:

          (a) any lack of validity or enforceability of any Letter of Credit or
Acceptance Draft;

          (b) the existence of any claim, setoff, defense or other right which
the Borrower or any other person may at any time have against the beneficiary
under the Letter of Credit or the Acceptance Draft, the Administrative Agent or
any Lender (other than the defense of payment in accordance with the terms of
this Agreement or a defense not otherwise waived hereunder based on the gross
negligence or willful misconduct of the Administrative Agent or any Lender) or
any other person in connection with this Agreement or any other transaction;

                                      -28-
<PAGE>

          (c) any draft or other document presented under any Letter of Credit
or Acceptance Draft proving to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;

          (d) payment by the Administrative Agent or any Lender under any Letter
of Credit against presentation of a draft or other document which does not
comply with the terms of such Letter of Credit;

          (e) the existence, character, quantity, quality, condition, packing,
value or delivery of any goods or other property relating to any Letter of
Credit or Acceptance Draft;

          (f) the time, place, manner or order in which shipment is made;

          (g) the provisions of any insurance policy or any act or omission of
any insurer, shipper, warehouseman, carrier, correspondent or other person;

          (h) any other circumstance or event whatsoever, whether or not similar
to any of the foregoing.

          Neither the Administrative Agent nor a Lender shall have any liability
or responsibility by reason of or in connection with the issuance or transfer of
any Letter of Credit or Acceptance Draft or any payment or failure to make
payment thereunder (irrespective of any of the circumstances referred to above),
or any error, omission, interruption, loss or delay in transmission or delivery
of any draft, notice or other communication under or relating to any Letter of
Credit or Acceptance Draft (including any document required to make a drawing
thereunder), any error in interpretation of technical terms or any consequence
arising from causes beyond the control of the Administrative Agent or a Lender,
provided that the foregoing shall not be construed to excuse the Administrative
Agent or a Lender from liability to the Borrower to the extent of damages
suffered by the Borrower that are caused by the Administrative Agent's or a
Lender's gross negligence or willful misconduct. It is understood that in making
any payment under any Letter of Credit or Acceptance Draft (x) the
Administrative Agent's and any Lender's exclusive reliance on the documents
presented to it under such Letter of Credit or Acceptance Draft as to any and
all matters set forth therein, including, without limitation, good faith
reliance on the amount of any draft presented under such Letter of Credit or
Acceptance Draft, whether or not the amount due to the beneficiary equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit or Acceptance Draft proves to be insufficient in any respect,
if such document on its face appears to be in order, and whether or not any
other statement or any other document presented

                                      -29-
<PAGE>

pursuant to such Letter of Credit or Acceptance Draft proves to be forged or
invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever and (y) any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit or Acceptance Draft with the
terms thereof shall, in each case, not be deemed willful misconduct or gross
negligence of the Administrative Agent or any Lender.

     2.23  Ineligibility of Acceptance Drafts. In the event that any Acceptance
           ----------------------------------
Draft accepted pursuant to this Agreement does not, for reasons beyond the
control of the Administrative Agent, comply at the time of its acceptance with
applicable regulations of the Board governing bankers' acceptances and would not
be eligible under such regulations for discount with a Federal Reserve lender or
if for any other reason any Acceptance Draft is deemed by the Administrative
Agent not eligible for discount, the Borrower will, upon receipt of written
notice from the Administrative Agent, forthwith pay to the Administrative Agent
any additional cost or costs, as determined by the Administrative Agent,
incurred by the Administrative Agent (including, without limitation, any costs
resulting from a higher discount rate upon disposition of such Acceptance Draft
by the Administrative Agent, any funding costs resulting from a higher discount
rate upon disposition of such Acceptance Draft by the Administrative Agent,
reserve requirements or additional premium liability to the Federal Deposit
insurance Corporation) in connection with such Acceptance Draft on account of
such noncompliance or ineligibility.

     3.5   Legal Bar. The execution, delivery and performance of each of the
           ---------
Loan Documents and the borrowings hereunder and the use of the proceeds thereof,
will not violate any of the Requirements of Law or Contractual Obligations of

          (h)  The rendition by any court of a final judgment or judgments
against the Borrower or any of its Subsidiaries which shall not be

          (j)  Any representation or warranty made or deemed herein or in any
Loan Document or which is contained in any certificate, document or financial or

the Administrative Agent with the written consent of the Required Lenders may,
and upon the written request of the Required Lenders shall by notice of default

                                      -50-

                       SECTION 9.  ADMINISTRATIVE AGENT
                                   --------------------

     In order to expedite the transactions contemplated by this Agreement,
Mellon Bank, N.A. is hereby appointed to act as Administrative Agent on behalf
of the Lenders.  Each of the Lenders and each subsequent holder of any Note or
issuer of any Letter of Credit, irrevocably authorizes the Administrative Agent
to take such action on its behalf and to exercise such powers hereunder and
under the Loan Documents as are specifically delegated to or required of the
Administrative Agent by the terms hereof and the terms thereof together with
such powers as are reasonably incidental thereto.  Neither the Administrative
Agent nor any of its directors, officers, employees or Administrative Agents
shall be liable as such for any action taken or omitted to be taken by it or
them hereunder or under any of the Loan Documents or in connection herewith or
therewith (a) at the request or with the approval of the Lenders (or, if
otherwise specifically required hereunder or thereunder, the consent of the
Lenders) or (b) in the absence of its or their own gross negligence or willful
misconduct.

     The Administrative Agent is hereby expressly authorized on behalf of the
Lenders, without hereby limiting any implied authority, (a) to receive on behalf
of each of the Lenders any payment of principal of or interest on the Notes
outstanding hereunder and all other amounts accrued hereunder paid to the
Administrative Agent, and promptly to distribute to each Lender its proper share
of all payments so received, (b) to distribute to each Lender copies of all
notices, agreements and other material as provided for in this Agreement or in
the other Loan Documents as received by such Administrative Agent and (c) to
take all actions with respect to this Agreement and the other Loan Documents as
are specifically delegated to the Administrative Agent.

     In the event that (a) the Borrower fails to pay when due the principal of
or interest on any Note, any amount payable under any Letter of Credit or
Acceptance Draft, or any fee payable hereunder or (b) the Administrative Agent
receives written notice of the occurrence of a Default or an Event of Default,
the Administrative Agent within a reasonable time shall give written notice
thereof to the Lenders; and shall take such action with respect to such Event of
Default or other condition or event as it shall be directed to take by the
Lenders; provided, however,

                                      -51-
<PAGE>

that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may take such action or refrain from taking
such action hereunder or under any other Loan Documents with respect to a
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders.

     The Administrative Agent shall not be responsible in any manner to any of
the Lenders for the effectiveness, enforceability, perfection, value,
genuineness, validity or due execution of this Agreement, the Notes or any of
the other Loan Documents or any other agreements or certificates, requests,
financial statements, notices or opinions of counsel or for any recitals,
statements, warranties or representations contained herein or in any such
instrument or be under any obligation to ascertain or inquire as to the
performance or observance of any of the terms, provisions, covenants,
conditions, agreements or obligations of this Agreement or any of the other Loan
Documents or any other agreements on a part of the Borrower and, without
limiting the generality of the foregoing, the Administrative Agent shall, in the
absence of knowledge to the contrary, be entitled to accept in good faith any
certificate furnished pursuant to this Agreement or any of the other Loan
Documents as conclusive evidence of the facts stated therein and shall be
entitled to rely in good faith on any note, notice, consent, certificate,
affidavit, letter, telegram, teletype message, statement, order or other
document which it believes in good faith to be genuine and correct and to have
been signed or sent by the proper person or persons.  It is understood and
agreed that the Administrative Agent may exercise its rights and powers under
other agreements and instruments to which it is or may be a party, and engage in
other transactions with the Borrower, as though it were not Administrative Agent
of the Lenders hereunder.

     The Administrative Agent shall promptly give notice to the Lenders of the
receipt or sending of any notice, schedule, report, projection, financial
statement or other document or information pursuant to this Agreement or any of
the other Loan Documents and shall promptly forward a copy thereof to each
Lender.

     Neither the Administrative Agent nor any of its directors, officers,
employees or Administrative Agents shall have any responsibility to the Borrower
on account of the failure or delay in performance or breach by any Lender other
than the Administrative Agent of any of its obligations hereunder or to any
Lender on account of the failure of or delay in performance

                                      -52-
<PAGE>

or breach by any other Lender or the Borrower of any of their respective
obligations hereunder or in connection herewith.

     The Administrative Agent may consult with legal counsel selected by it in
connection with matters arising under this Agreement or any of the other Loan
Documents and any action taken or suffered in good faith by it in accordance
with the opinion of such counsel shall be full justification and protection to
it. The Administrative Agent may exercise any of its powers and rights and
perform any duty under this Agreement or any of the other Loan Documents through
Administrative Agents or attorneys.

     The Administrative Agent and the Borrower may deem and treat the payee or
most recent assignee pursuant to Section 10.3 hereof, as applicable, of any Note
as the holder thereof until written notice of transfer shall have been delivered
as provided in Section 10.3 hereof by such payee to the Administrative Agent and
the Borrower.

     With respect to the Loans made hereunder, the Notes issued to it and any
other extension of credit applicable to it, the Administrative Agent in its
individual capacity and not as an Administrative Agent shall have the same
rights, powers and duties hereunder and under any other Agreement executed in
connection herewith as any other Lender and may exercise the same as though it
were not the Administrative Agent, and the Administrative Agent and its
affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Borrower or other affiliate thereof as if it were not
the Administrative Agent.

     Each Lender agrees (i) to reimburse the Administrative Agent in the amount
of such Lender's pro rata share (based on its Revolving Credit Commitment
hereunder) of any reasonable out-of-pocket expenses incurred for the benefit of
the Lenders by the Administrative Agent, including reasonable fees and
disbursements of counsel to the Administrative Agent and compensation of
Administrative Agents and employees paid for services rendered on behalf of the
Lenders, not reimbursed by the Borrower pursuant to Section 10.4 hereof and (ii)
to indemnify and hold harmless the Administrative Agent and any of its
directors, officers, employees or Administrative Agents, on demand, in the
amount of its pro rata share (based on its Revolving Credit Commitment
hereunder), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed on, incurred by or
asserted against it in its capacity as the Administrative Agent or any of them
in any way relating to or arising out of this Agreement or

                                      -53-
<PAGE>

any of the other Loan Documents or any action taken or omitted by it or any of
them under this Agreement or any of the other Loan Documents, to the extent not
reimbursed by the Borrower pursuant to Section 10.4 hereof; provided, however,
that no Lender shall be liable to the Administrative Agent for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the gross negligence or
willful misconduct of the Administrative Agent or any of its directors,
officers, employees or Administrative Agents.

     Each Lender acknowledges that it has, independently and without reliance
upon the Administrative Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and any other Loan Document to which such
Lender is a party. Each Lender also acknowledges that it will, independently and
without reliance upon the Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document, any related agreement or any
document furnished hereunder.

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower.  Upon any such resignation, the Lenders
shall have the right to appoint a successor Administrative Agent.  If no
successor Administrative Agent shall have been so appointed by such Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent gives notice of its resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a Lender with an office (or an affiliate
with an office) in the New York metropolitan area having a combined capital and
surplus of at least $500,000,000.  Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Lender, such successor shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder and under
each of the other Loan Documents.  After any Administrative Agent's resignation
hereunder, the provisions of this Article shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

                                      -54-
<PAGE>

     The Lenders hereby acknowledge that the Administrative Agent shall be under
no duty to take any discretionary action permitted to be taken by the
Administrative Agent pursuant to the provisions of this Agreement or any of the
other Loan Documents unless it shall be requested in writing to do so by the
Required Lenders.

Agreement or any other Loan Document, shall be considered to have been relied
upon by the Lenders and shall survive the making by the Lenders of the Revolving

effect as long as the principal of or any accrued interest on the Notes or any

     10.3  Successors and Assigns: Participations.  (a)  Whenever in this
           --------------------------------------
Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf the Borrower, any Guarantor, any ERISA
Affiliate, any Subsidiary of any thereof, the Administrative Agent or the
Lenders, that are contained in this Agreement shall bind and inure to the
benefit of their respective successors and assigns.  Without limiting the
generality of the foregoing, the Borrower specifically confirms that the
Administrative Agent and each Lender may at any time and from time to time
assign or pledge or otherwise grant a security interest in any Loan or any Note
or Acceptance Draft (or any part thereof) to any Federal Reserve Bank.  The
Borrower may not assign or transfer any of its rights or obligations hereunder
without the written consent of all the Lenders.

           (b)   Each Lender, without the consent of the Borrower, may sell
participations to one or more Lenders or other entities in all or a portion of
its rights and obligations under this Agreement (including, without limitation,
all or a portion of its Revolving Credit Commitment) and the Loans owing to it
and undrawn Letters of Credit and Acceptance Drafts and the Notes held by it);
provided, however, that (i) such Lender's obligations under this Agreement
(including, without limitation, its Revolving Credit Commitment) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) the Lenders

                                      -56-
<PAGE>

or other entities buying participations shall be entitled to the cost protection
provisions contained in Sections 2.10 (except to the extent that application of
such Section 2.10 to such Lenders and entities would cause the Borrower to make
duplicate payments thereunder) and Section 2.7 hereof, and (iv) the Borrower,
the Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.

          (c)   Each Lender may assign by novation as of the date of assignment,
to any one or more Lenders or other entities with the consent of the Borrower
(which consent shall be given in its sole discretion unless the Administrative
Agent waives its additional fee for the assignment to such Lender or Lenders in
which case consent will not be unreasonably withheld) and the Administrative
Agent (which consent will not be unreasonably withheld) (except that in the case
of an assignment by a Lender to one of its Affiliates or to another Lender no
such consent of the Administrative Agent shall be required), all or a portion of
its interests, rights and obligations under this Agreement and the other Loan
Documents (including, without limitation, all or a portion of its Revolving
Credit Commitment and the same portion of the Loans and undrawn Letters of
Credit and Acceptance Drafts at the time owing to it and the Notes held by it),
provided, however, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all of the assigning Lender's rights and obligations
under this Agreement, which shall include the same percentage interest in the
Loans, Letters of Credit, Acceptance Drafts and Notes, (ii) the amount of the
Revolving Credit Commitment of the assigning Lender being assigned pursuant to
each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative Agent) shall
be in a minimum principal amount of $3,000,000 Revolving Credit Commitment of
such Lender and (iii) the parties to each such assignment shall execute and
deliver to the Administrative Agent, for its acceptance and recording in the
Register (as defined below), an assignment and acceptance in form and substance
acceptable to the Administrative Agent (an "Assignment and Acceptance"),
together with any Note subject to such assignment and a processing and
recordation fee of $2,500.00 payable by the assigning Lender. Upon such
execution, delivery, acceptance and recording and after receipt of the written
consent of the Administrative Agent, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be at least five
(5) Business Days after the execution thereof, (x) the assignee thereunder shall
be a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder and under the other Loan
Documents and (y)

                                      -57-
<PAGE>

the Lender which is assignor thereunder shall, to the extent provided in such
Assignment and Acceptance, be released from its obligations under this Agreement
and the other Loan Documents (and, in the case of an Assignment and Acceptance
covering all or the remaining portion of an assigning Lender's rights and
obligations under this Agreement, such Lender shall cease to be a party hereto
and thereto).

          (d)  By executing and delivering an Assignment and Acceptance, the
Lender which is assignor thereunder and the assignee thereunder confirm to, and
agree with, each other and the other parties hereto as follows: (i) other than
the representation and warranty that it is the legal and beneficial owner of the
interest being assigned thereunder free and clear of any adverse claim,
responsibility with respect to any statements, warranties or representations
made in or in connection with this Agreement or the execution, legality,
validity, enforceability, perfection, genuineness, sufficiency or value of this
Agreement, the other Loan Documents or any other instrument or document
furnished pursuant hereto or thereto; (ii) such Lender makes no representation
or warranty and assumes no responsibility with respect to the financial
condition of the Borrower, any Guarantor or any Subsidiary of any thereof or the
performance or observance by the Borrower, any Guarantor or any Subsidiary of
any thereof of any of their respective obligations under this Agreement or any
of the other Loan Documents or any other instrument or document furnished
pursuant hereto or thereto; (iii) such assignee confirms that it has received a
copy of this Agreement, and the other Loan Documents, together with copies of
financial statements and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such Lender or any other Lender and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes the
Administrative Agent to take such action as the Administrative Agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vi) such assignee agrees that it will
perform in accordance with their terms all of the obligations which by the terms
of this Agreement are required to be performed by it as a Lender.

          (e)  The Administrative Agent shall maintain at its address referred
to in Section 10.1 hereof a copy of each Assignment and Acceptance delivered to
it and a register for the

                                      -58-
<PAGE>

recordation of the names and addresses of the Lenders and the Revolving Credit
Commitment of, and principal amount of the Loans owing to, each Lender from time
to time (the "Register"). The entries in the Register shall be conclusive, in
the absence of manifest error or written notice to the contrary delivered in
accordance with this Agreement, and the Borrower, the Administrative Agent and
the Lenders may treat each person whose name is so recorded in the Register as a
Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Lender at any reasonable time
and from time to time upon reasonable prior notice.

          (f)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee together with any Note subject to such
assignment and the written consent to such assignment, the Administrative Agent
shall (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Lenders and the Borrower. Within five (5) Business Days after receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent in exchange for each surrendered Note or Notes a new Note
to the order of such assignee in an amount equal to the Revolving Credit
Commitment assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained any Revolving Credit Commitment hereunder, a new
Note to the order of the assigning Lender in an amount equal to the Revolving
Credit Commitment retained by it hereunder. Such new Note shall be in an
aggregate principal amount equal to the aggregate principal amount of such
surrendered Note shall be dated the effective date of such Assignment and
Acceptance and shall otherwise be in substantially the form of Exhibit A hereto.

          (g)  Notwithstanding any other provision herein, any Lender may, in
connection with any assignment or participation or proposed assignment or
participation pursuant to this Section 10.03, disclose to the assignee or
participant or proposed assignee or participant, any information relating to the
Borrower furnished to such Lender by or on behalf of the Borrower in connection
with this Agreement; provided, however, that prior to any such disclosure, each
such assignee or participant or proposed assignee or participant shall agree to
preserve the confidentiality of any confidential information relating to the
Borrower received from such Lender.

          (h)  Nothing in this Section shall limit or restrict the ability of
any Lender to sell, rediscount or otherwise dispose of any Acceptance Draft.

                                      -59-

           (i)  The annual Administrative Agent's fee shall be payable in
accordance with the provisions of Section 5.11 hereof.

     10.4  Expenses: Indemnity. (a) The Borrower agrees to pay all reasonable
           -------------------
out-of-pocket expenses incurred by the Administrative Agent in connection with
the preparation of this Agreement, the Notes and the other Loan Documents or
with any amendments, modifications or waivers of the provisions hereof or
thereof or incurred by the Administrative Agent or any of the Lenders in
connection with the enforcement, adjudication or protection of its rights in
connection with this Agreement or any of the other Loan Documents or with the
Loans made or the Notes or Letters of Credit or Acceptance Drafts issued
hereunder or the use of proceeds therefrom, or in connection with any pending or
threatened action, proceeding, or investigation relating to the foregoing,
including but not limited to the reasonable fees and disbursements of counsel
for the Administrative Agent and, in connection with such enforcement or
protection, the reasonable fees and disbursements of counsel for the Lenders.
The Borrower further indemnifies the Lenders from and agrees to hold them
harmless against any documentary taxes, assessments or charges made by any
governmental authority by reason of the execution and delivery of this Agreement
or the Notes.

           (b)  The provisions of this Section 10.4 shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or the Notes, or any investigation made by or on
behalf of the Administrative Agent or any Lender. All amounts due under this
Section 10.04 shall be payable on written demand therefor.

     10.5  Applicable Law.  THIS AGREEMENT AND THE NOTES SHALL BE CONSTRUED IN
           --------------
ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

     10.6  Right of Setoff.  If an Event of Default shall have occurred and be
           ---------------
continuing, upon the request of the Lenders each Lender shall and is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of the Borrower or
any Guarantor against any and all of the obligations of the Borrower now or
hereafter existing under this Agreement and the Notes held by such Lender,
irrespective of whether or not

                                      -60-
<PAGE>

such Lender shall have made any demand under this Agreement or the Notes and
although such obligations may be unmatured. Each Lender agrees to notify
promptly the Administrative Agent and the Borrower and any applicable Guarantor
after any such setoff and application made by such Lender, but the failure to
give such notice shall not affect the validity of such setoff and application.
The rights of each Lender under this Section are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which may be
available to such Lender.

     10.7  Payments on Business Days.  Should the principal of or interest on
           -------------------------
the Notes or any fee or other amount payable hereunder become due and payable on
other than a Business Day, payment in respect thereof may be made on the next
succeeding Business Day (except as otherwise specified in the definition of
"Interest Period"), and such extension of time shall in such case be included in
computing interest, if any, in connection with such payment.

     10.8  Waivers; Amendments.  (a) No failure or delay of any Lender in
           -------------------
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such right or power, preclude
any other or further exercise thereof or the exercise of any other right or
power.  The rights and remedies of the Lender hereunder are cumulative and not
exclusive of any rights or remedies which they may otherwise have.  No waiver of

     or redemption of shares of the series.

          (g) The amounts payable on, and the preferences, if any, of shares of
     the series in the event of any voluntary or involuntary liquidation,
     dissolution or winding up of the affairs of the Corporation.

          (h) Whether the shares of the series shall be convertible into or
     exchangeable for shares of any other class or series, or any other
     security, of the Corporation or any other corporation, and, if so, the
     specification of such other class or series or such other security, the
     conversion or exchange price or prices or rate or rates, any adjustments
     thereof, the date or dates at which such shares shall be convertible or
     exchangeable and all other terms and conditions upon which such conversion
     or exchange may be made.

          (i) Restrictions on the issuance of shares of the same series or of
     any other class or series.
<PAGE>

          (j) The voting rights, if any, of the holders of shares of the series.

     The Common Stock shall be subject to the express terms of the Preferred
Stock and any series thereof. Except as may otherwise be provided in this
restated certificate of incorporation, in a Preferred Stock Designation or by
applicable law, the holders of shares of Common Stock shall be entitled to one
vote for each such share upon all questions presented to the stockholders, the
Common Stock shall have the exclusive right to vote for the election of
directors and for all other purposes, and holders of Preferred Stock shall not
be entitled to vote at or receive notice of any meeting of stockholders.

     Subject to the rights of the holders of any series of Preferred Stock
pursuant to the terms of this restated certificate of incorporation or any
resolution or resolutions providing for the issuance of such series of stock
adopted by the Board of Directors, the number of authorized shares of Preferred
Stock or Common Stock may be increased or decreased (but not below the number of
shares thereof then outstanding) by the affirmative vote of the holders of a
majority of the stock of the Corporation entitled to vote generally in the
election of directors irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of the State of Delaware.

     FIFTH:  The authorized number of members of the Board of Directors will be
fixed from time to time by resolution adopted by the affirmative vote of a
majority of the entire Board of Directors but in no event may the number be less
than three.

     The Directors shall be divided into three classes, each consisting of one-
third of such directors, as nearly as may be, designated Class I, Class II and
Class III. Class I directors shall initially serve until the 2000 meeting of
stockholders; Class II directors shall initially serve until the 2001 meeting of
stockholders; and Class III directors shall initially serve until the 2002
meeting of stockholders. Commencing with the stockholders' meeting in 2000, and
at each succeeding annual stockholders' meeting, successors to the class of
directors whose term expires at such annual stockholders' meeting shall be
elected for a three-year term. If the number of such directors is changed, an
increase or decrease in such directors shall be apportioned among the classes so
as to maintain the number of directors comprising each class as nearly equal as
possible, and any additional directors of any class shall hold office for a term
which shall coincide with the remaining term of such class. A director shall
hold office until the annual stockholders' meeting for the year in which his
term expires and until his successor shall be elected and shall qualify,
subject, however, to prior death, resignation, retirement, disqualification, or
removal from office.

     Except as otherwise required by law, any vacancy on the board of directors
that results from an increase in the number of directors and any other vacancy
occurring in the board of directors shall only be filled by a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director. Any director elected to fill a vacancy not resulting from an increase
in the number of directors shall have the same remaining term as that of his or
her predecessor. A director may be removed only for cause by the stockholders.
Notwithstanding the foregoing, whenever the holders of any one or more series of
Preferred Stock issued by the Corporation shall have the right, voting
separately by class or series, to elect directors at an annual or special
meeting of stockholders, the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the terms of this
restated certificate of incorporation applicable thereto and such directors so
elected shall not be divided into classes pursuant to this Article Fifth, in
each case unless expressly provided by such terms. During any period when the
holders of any series of Preferred Stock have the right to elect additional
directors as provided for or fixed pursuant to the provisions of Article Fourth
hereof, then upon commencement and for the duration of the period during which
such right continues: (i) the then otherwise total authorized number of
directors of the Corporation shall automatically be increased by such specified
number of directors, and the holders of such Preferred Stock shall be entitled
to elect the additional directors so provided for or fixed pursuant to said
provisions, and (ii) each such additional director shall serve until such
director's successor shall have been duly elected and qualified, or until such
director's right to hold such office terminates pursuant to said provisions,
whichever occurs earlier, subject to his earlier death, disqualification,
resignation or removal. Except as otherwise provided by the Board of Directors
in the resolution or resolutions establishing such series, whenever the holders
of any series of Preferred Stock having such right to elect additional directors
are divested of such right pursuant to the provisions of such stock, the terms
of office of all such additional directors elected by the holders of such stock,
or elected to fill any vacancies resulting from the death, resignation,
disqualification or removal of such additional directors, shall forthwith
terminate and the total and authorized number of directors of the Corporation
shall be reduced accordingly.

     SIXTH: Meetings of stockholders may be held within or without the State of
Delaware as the By-laws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the By-laws of the Corporation. The election of
directors need not be by written ballot unless the By-laws so provide.

     SEVENTH: The Board of Directors of the Corporation is authorized and
empowered from time to time in its discretion to make, alter, amend or repeal
By-laws of the Corporation.

     EIGHTH:  A director of the Corporation shall not be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except to the extent such exemption from liability or
limitation thereof is not permitted under the General Corporation Law of the
State of Delaware, as the same exists or may hereafter be amended. Any
amendment, modification or repeal of the foregoing sentence shall not adversely
affect any right or protection of a director of the Corporation hereunder in
respect of any act or omission occurring prior to the time of such amendment,
modification or repeal.

     NINTH:

     1.  Right to Indemnification.  The Corporation shall indemnify and hold
harmless, to the fullest extent permitted by applicable law as it presently
exists or may hereafter be amended, any person (an "Covered Person") who was or
is made or is threatened to be made a party or is otherwise involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (a "Proceeding"), by reason of the fact that he or she, or a
person for whom he or she is the legal representative, is or was a director or
officer of the Corporation or, while a director or officer of the Corporation,
is or was serving at the request of the Corporation as a director, officer,
employee, manager or agent of another corporation or of a partnership, limited
liability company, joint venture, trust, enterprise or nonprofit entity,
including service with respect to employee benefit plans, against all liability
and loss suffered and expenses (including attorneys' fees) reasonably incurred
by such Covered Person. Notwithstanding the preceding sentence, except as
otherwise provided in Section 3 of this Article Ninth, the Corporation shall be
required to indemnify an Covered Person in connection with a Proceeding (or part
thereof) commenced by such Covered Person only if the commencement of such
Proceeding (or part thereof) by the Covered Person was authorized by the Board
of Directors of the Corporation. Notwithstanding any provision herein to the
contrary, the Corporation shall not be required to advance expenses to an
Covered Person who is a party to an action, suit or proceeding brought by the
Corporation and approved by a majority of the Board of Directors of the
Corporation which alleges willful misappropriation of corporate assets by such
Covered Person, disclosure of confidential information in violation of such
Covered Person's fiduciary or contractual obligations to the Corporation or any
other willful and deliberate breach in bad faith of such Covered Person's duty
to the Corporation or its stockholders.

     2.  Prepayment of Expenses.  Except as otherwise provided in Section 1 of
this Article Ninth, the Corporation shall pay the expenses (including attorneys'
fees) incurred by an Covered Person in defending any Proceeding in advance of
its final disposition, provided, however, that to the extent required by law,
such payment of expenses in advance of the final disposition of the Proceeding
shall be made only upon receipt of an undertaking by the Covered Person to repay
all amounts advanced if it should be ultimately determined that the Covered
Person is not entitled to be indemnified under this Article Ninth or otherwise.

     3.  Claims.  If a claim for indemnification or advancement of expenses
under this Article Ninth is not paid in full within sixty days after a written
claim therefor by the Covered Person has been received by the Corporation, the
Covered Person may file suit to recover the unpaid amount of such claim and, if
successful in whole or in part, shall be entitled to be paid the expense of
prosecuting such claim. In any such action the Corporation shall have the burden
of proving that the Covered Person is not entitled to the requested
indemnification or advancement of expenses under applicable law.

     4.  Nonexclusivity of Rights.  The rights conferred on any Covered Person
by this Article Ninth shall not be exclusive of any other rights which such
Covered Person may have or hereafter acquire under any statute, provision of
this restated certificate of incorporation, the Corporation's by-laws or any
agreement, vote of stockholders or disinterested directors or otherwise.

     5.  Other Sources.  The Corporation's obligation, if any, to indemnify or
to advance expenses to any Covered Person who was or is serving at its request
as a director, officer, employee, manager or agent of another corporation,
partnership, limited liability company, joint venture, trust, enterprise or
nonprofit entity shall be reduced by any amount such Covered Person may collect
as indemnification or advancement of expenses from such other corporation,
partnership, limited liability company, joint venture, trust, enterprise or non-
profit enterprise.

     6.  Amendment or Repeal.  Any repeal or modification of the foregoing
provisions of this Article Ninth shall not adversely affect any right or
protection hereunder of any Covered Person in respect of any act or omission
occurring prior to the time of such repeal or modification.

     7.  Other Indemnification and Prepayment of Expenses.  This Article Ninth
shall not limit the right of the Corporation, to the extent and in the manner
permitted by law, to indemnify and to advance expenses to persons other than
Covered Persons when and as authorized by appropriate corporate action.

     TENTH:  No action required to be taken or which may be taken at any annual
or special meeting of stockholders of the Corporation may be taken without a
meeting; and the power of the stockholders to consent in writing, without a
meeting, to the taking of any action is specifically denied.

     ELEVENTH:  Except as otherwise required by law, the provisions of Articles
Fifth and Tenth and the provisions of this Article Eleventh may not be amended
in any respect unless such amendment is approved by the affirmative vote of the
holders of two thirds in voting power of the outstanding stock of the
Corporation entitled to vote generally.

     time to time (such shares, the "eFusion Merger Shares", and such merger
     agreement, the "eFusion Merger Agreement"), shall be subject to the
     restrictions set forth in Appendix A to this certificate of incorporation."

     Further, the Corporation's certificate of incorporation is amended to add
new Appendix A, which Appendix A shall read in its entirety as follows:

     "                            APPENDIX A

          1.  General Restrictions.  Except as otherwise provided in Section 2
     of this Appendix A or as otherwise consented to in writing by this
     Corporation in its absolute discretion, until the one hundred and eightieth
     (180th) day after the Closing Date, the Shareholders shall not (x) effect
     an offer, pledge, sale, contract of sale, short sale, sale of any option or
     contract to purchase, purchase of any option or contract to sell, grant of
     any option, right or warrant to purchase, gift or other transfer or
     disposition of, directly or indirectly, any eFusion Merger Shares (as such
     term is defined in Article Twelfth of this certificate of incorporation) or
     (y) enter into any swap or other arrangement that transfers all or a
     portion of the economic consequences associated with the ownership of any
     eFusion Merger Shares (regardless of whether any of the transactions
     described in clause (x) or (y) (each, a "Disposition") are to be settled by
     the delivery of eFusion Merger Shares, or such other securities, in cash or
     otherwise). This Corporation shall be authorized to cause its transfer
     agent to decline to transfer and/or to note stop transfer restrictions on
     the transfer books and records of this Corporation with respect to any of
     the eFusion Merger Shares.

          2.  Sequential Lapse of Restrictions.  During the Initial Period,
     each Shareholder shall have the right to make a Disposition of up to ten
     percent (10%) of the eFusion Merger Shares issuable to such Shareholder
     upon consummation of the eFusion Merger or subsequent thereto pursuant to
     the terms of the Escrow Agreement. During the Second Period, each
     Shareholder shall have the right to make a Disposition of up to an
     additional ten percent (10%) of the eFusion Merger Shares issuable to such
     Shareholder upon consummation of the Merger or subsequent thereto pursuant
     to the terms of the Escrow Agreement, together with any eFusion Merger
     Shares which such Shareholder had the right to subject to a Disposition,
     but did not subject to a Disposition, during the Initial Period. The
     restrictions set forth in Section 1 above shall cease to apply on the one
     hundred and eightieth (180th) day after the Closing Date.
<PAGE>

          3.  Certificates.  The certificates representing the eFusion
     Merger Shares shall bear a conspicuous legend, in addition to any other
     legend required by the eFusion Merger Agreement, referring to the
     restrictions set forth in this Appendix A; provided, however, at this
     Corporation's discretion, this Corporation may issue without legend
     certificates representing the eFusion Merger Shares which may be subject to
     a Disposition during the Initial Period.  At a Shareholder's written
     request, this Corporation will remove the legends required by this Appendix
     A at any time after the applicable restrictive period has lapsed.

          4.  Certain Definitions.  For purposes of this Appendix A, the
     following terms shall have the following meanings:

               "Closing" shall mean the closing provided for by the eFusion

     becomes effective under the laws of the State of Oregon.

               "Initial Period" shall mean the period commencing at the
     Effective Time and expiring on November 9, 2000; provided, however, if the
     Effective Time occurs after November 9, 2000, the term "Initial Period"
     shall mean the first thirty days after the Effective Time.

               "Second Period" shall mean the period commencing on the first day
     after the last day of the Initial Period and expiring on the one hundred
     and eightieth (180th) day after the Closing Date.

               "Shareholders" shall mean each person or entity that is a
     shareholder of eFusion, Inc., an Oregon corporation, immediately prior to
     the consummation of the eFusion Merger (as such term is defined in Article
     Twelfth of this certificate of incorporation)."                     "
