                                      -8-
<PAGE>

any one time outstanding (including, without duplication, the face amount of all
outstanding Letters of Credit and unreimbursed draws on Letters of Credit) up to
but not exceeding the lesser of the Revolving Loan Commitment I as then in
effect or the Collateral Coverage Base. Subject to the terms of this Agreement,
during the Revolving Credit Period I the Borrowers may borrow, repay and
reborrow (all as provided herein).

               (ii)   On or before the last Business Day of each week, Borrowers
shall execute a Borrowing Base Certificate ("Borrowing Base Certificate")
prepared by Borrowers and certified by their corporate controller or chief
financial officer setting forth the present values of the Collateral and
Borrowers' compliance with the Collateral Coverage Base and the Borrowing Base.

               (iii)  Each Lender agrees severally to make cash Revolving Loan I
Advances to Borrowers, as a part of the Revolving Loan I, subject to the terms
of this Agreement, up to such Lender's Pro Rata Percentage of the Revolving Loan
I, as more fully set forth in Section 2.5 hereof.

          (b)  (i)    During the Revolving Credit Period I, Borrowers may obtain
letters of credit (each a "Letter of Credit" and, collectively, "Letters of
Credit") from the Issuer, on behalf of all Lenders, in an aggregate amount not
to exceed $20,000,000 (measured by the face amount thereof) at any time
outstanding, upon prior approval of the Issuer, on such terms (including without
limitation the expiry date, which Borrowers agree will in no event be twelve
months beyond the Commitment Termination Date I) as the Issuer may require and
with such documentation, including Issuer's then standard Letter of Credit
Application and Security Agreement, as shall be satisfactory in form and
substance to the Issuer. Borrowers will pay to Agent, for the account of each
Lender in accordance with their Pro Rata Percentages, a letter of credit fee for
each Letter of Credit issued hereunder in the amount of 1% per annum of the face
amount of such Letter of Credit, payable quarterly in arrears (measured from the
date of issuance) (the "L/C Fee"). Borrowers will pay to Issuer, for its own
account, all issuance, negotiation, draw and other administrative fees from time
to time assessed by Issuer in accordance with Issuer's then standard fee
schedule for the issuance and administration of letters of credit.

               (ii)   (A)  Immediately upon the issuance of any Letter of
Credit, Issuer is deemed to have granted to each other Lender, and each other
Lender is hereby deemed to have acquired, an undivided participating interest
(without recourse to or warranty by Issuer), in accordance with each such other
Lender's respective Pro Rata Percentage, in all of Issuer's rights and
liabilities with respect to such Letter of Credit. Each Lender shall be directly
and unconditionally obligated to Issuer, according to its Pro Rata Percentage,
to reimburse Issuer for any draws not reimbursed by Borrowers in accordance with
the terms hereof, made at any time without regard to the occurrence of a Default
or Event of Default (including, without limitation, any draw made following the
commencement of any bankruptcy, reorganization, receivership, liquidation or
dissolution proceeding with respect to any Borrower) under any Letter of Credit
outstanding under the Revolving Loan I.

                      (B)  Each Letter of Credit issued from time to time under
the Revolving Loan I which remains undrawn (and the amounts of draws on Letters
of Credit prior to payment as hereinafter set forth) shall reduce dollar for
dollar the amount available to be borrowed by Borrowers under the Revolving Loan
I.

                      (C)  In the event of any request for drawing under any
Letter of Credit by the beneficiary thereof, Issuer shall promptly notify
Borrowers and Borrowers shall immediately reimburse Issuer on the day when such
drawing is honored, including by way of a cash Revolving Loan I Advance under
the Revolving Loan I if otherwise available pursuant to

                                      -9-
<PAGE>

this Agreement. Borrowers' reimbursement obligation for draws under Letters of
Credit shall herein be referred to collectively as Borrowers' "Reimbursement
Obligations". All of Borrowers' Reimbursement Obligations hereunder with respect
to Letters of Credit shall apply unconditionally and absolutely to, and shall be
joint and several with respect to, Letters of Credit issued hereunder on behalf
of Borrowers.

                      (D)  (1)  In the event that Borrowers shall fail to
reimburse Issuer as provided in subpart (C) above in an amount equal to the
amount of the drawing honored by Issuer under a Letter of Credit, Issuer shall
promptly notify each Lender of the unreimbursed amount of such drawing and of
such Lender's participation therein based on such Lender's Pro Rata Percentage.
Each Lender shall make available to Issuer an amount equal to its respective
participation in same day funds, at the office of Issuer specified in such
notice, not later than 1:00 p.m. (Philadelphia time) on the Business Day after
the date notified by Issuer. In the event that any Lender fails to make
available to such Issuer the amount of such Lender's participation based on such
Lender's Pro Rata Percentage in such Letter of Credit, as provided in this
Section 2.1.1(b), Issuer shall be entitled to recover such amount on demand from
such Lender together with interest at the Fed Funds Rate for one (1) Business
Day and thereafter at two (2) percentage points above the Agent's Prime Rate.
Nothing in this Section shall be deemed to relieve any Lender from its
obligation to pay all amounts payable by it under this Section with respect to
any Letter of Credit issued by Issuer or to prejudice any rights that Issuer may
have against a Lender as a result of any default by such Lender hereunder and no
Lender shall be responsible for the failure of any other Lender to pay its
respective participation, based on its Pro Rata Percentage, payable under this
Section.

                           (2)  In connection with the failure of any Lender to
make available to Issuer the amount of such Lender's participation in any Letter
of Credit, such Lender hereby agrees to indemnify Issuer from and against any
and all costs and expenses (including, without limitation, reasonable attorneys'
fees, allocated costs of internal counsel and the costs in connection with any
related litigation) which Issuer may incur or be subject to as a consequence,
direct or indirect, of the failure of such Lender to make available its
participation in such Letter of Credit. Notwithstanding anything to the contrary
contained in this Section, no Lender failing to provide its participation in any
Letter of Credit shall have any obligation to indemnify Issuer in respect of any
liability incurred by Issuer arising solely out of the gross negligence or
willful misconduct of Issuer.

                      (E)  The obligation of Borrowers to reimburse Issuer for
drawings made (or Lenders for cash Revolving Loan I Advances made to cover
drawings made) under the Letters of Credit and the obligations of Lenders to
Issuer under Section 2.1.1(b)(ii)(D) shall be unconditional and irrevocable and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances including, without limitation, the following circumstances:

                           (1) any lack of validity or enforceability of any
Letter of Credit;

                           (2) the existence of any claim, setoff, defense or
other right that Borrowers or any other Person may have at any time against a
beneficiary or any transferee of any Letter of Credit (or any Person for whom
any such beneficiary or transferee may be acting), Issuer, Agent, any Lender or
any other Person, whether in connection with this Agreement, the transactions
contemplated herein or any unrelated transaction;

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

                                      -10-
<PAGE>

                           (4) payment by Issuer under any Letter of Credit
against presentation of a demand, draft or certificate, or other document that
does not comply with the terms of such Letter of Credit unless Issuer shall have
acted with willful misconduct or gross negligence in issuing such payment; or

                           (5) the fact that a Default or Event of Default shall
have occurred and be continuing.

                      (F)  (1) In addition to amounts payable as elsewhere
provided in this Section, without duplication, Borrowers hereby agree to
protect, indemnify, pay and save Issuer, Agent and Lenders harmless from and
against any and all claims, demands, liabilities, damages, losses, costs,
charges and expenses (including reasonable attorneys' fees) which Issuer may
incur or be subject to as a consequence, direct or indirect, of (A) the issuance
of the Letters of Credit or (B) the failure of Issuer to honor a drawing under
any Letter of Credit as a result of any act or omission, whether rightful or
wrongful, of any present or future de jure or de facto government or
                                   --------   ---------
governmental authority (all such acts or omissions herein called "Government
Acts").

                           (2) As between Borrowers and Issuer, Agent, and
Lenders, Borrowers assume all risks of the acts and omissions of, or misuse of
the Letters of Credit issued by Issuer by, the respective beneficiaries of such
Letters of Credit. In furtherance and not in limitation of the foregoing, Issuer
shall not be responsible: (a) for the form, validity, sufficiency, accuracy,
genuineness or legal effects of any document submitted by any party in
connection with the application for and issuance of such Letters of Credit, even
if it should in fact prove to be in any or all respects invalid, insufficient,
inaccurate, fraudulent or forged; (b) for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
such Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, that may prove to be invalid or ineffective for any reason;
(c) for failure of the beneficiary of any such Letter of Credit to comply fully
with conditions required in order to draw upon such Letter of Credit so long as
Issuer acts in good faith and without gross negligence or willful misconduct;
(d) for errors, omissions, interruptions or delays in transmission or delivery
of any messages, by mail, cable, telegraph, telex or otherwise, whether or not
they are in cipher, unless any of the foregoing are caused by Issuer's gross
negligence or willful misconduct; (e) for errors in interpretation of technical
terms; (f) for any loss or delay in the transmission of any document required in
order to make a drawing under any such Letter of Credit or of the proceeds
thereof, unless caused by Issuer's gross negligence or willful misconduct; (g)
for the misapplication by the beneficiary of any such Letter of Credit of the
proceeds of any drawing under such Letter of Credit; and (h) for any
consequences arising from causes beyond the control of Issuer, including,
without limitation, any Government Acts. None of the above shall affect, impair,
or prevent the vesting of any of Issuer's rights or powers hereunder.

                           (3) In furtherance and extension and not in
limitation of the specific provisions hereinabove set forth, any action taken or
omitted by Issuer in connection with the Letters of Credit issued by it or the
related certificates, if taken or omitted in good faith, shall not create any
liability on the part of Issuer to Borrowers.

                           (4) The term "Lender" shall, unless the context
otherwise indicates, include the Issuer in its individual capacity as a Lender.

     2.1.2  Revolving Loan II.
            ------------------

            (a)  (i)  Subject to the terms and conditions of this Agreement,
each Lender hereby establishes for Borrowers a revolving credit facility
(collectively, the "Revolving Loan

                                      -11-
<PAGE>

II") pursuant to which Lenders will make cash loans hereinafter provided for in
this Section 2.1.2 (individually, a "Revolving Loan II Advance" and,
collectively, the "Revolving Loan II Advances") to or for the account of the
Borrowers, at any time and from time to time during the period (the "Revolving
Credit Period II") from the date hereof to and including the Commitment
Termination Date II, in an aggregate principal amount at any one time
outstanding up to but not exceeding the lesser of the Revolving Loan Commitment
II or the Borrowing Base. Subject to the terms of this Agreement, during the
Revolving Credit Period II the Borrowers may borrow, repay and reborrow (all as
provided herein).

                 (ii) Each Lender agrees severally to make Revolving Loan II
Advances to Borrowers, as part of the Revolving Loan II, subject to the terms of
this Agreement, up to such Lender's Pro Rata Percentage of the Revolving Loan
II, as more fully set forth in Section 2.5 hereof.

     2.2  Changes in Revolving Loan Commitments.
          --------------------------------------

     The Borrowers shall be entitled to terminate or reduce the Revolving Loan
Commitment I and/or the Revolving Loan Commitment II, provided that the
Borrowers shall give notice of each such termination or reduction to the Agent
as provided in Section 2.3 hereof and that any partial reduction of either
Revolving Loan Commitment shall be in an aggregate amount equal to $100,000 or
an integral multiple thereof, and, provided further, that Borrowers shall have
the right hereunder to reduce or terminate the Revolving Loan Commitment I only
if the Revolving Loan Commitment II has been terminated. Any such termination or
reduction shall be permanent and irrevocable.

     2.3  Notices.
          --------

     SSI, as agent hereunder for the Borrowers, shall give the Agent telephonic
and written notice of each termination or reduction of either of the Revolving
Loan Commitments, each borrowing, and repayment of either Revolving Loan. All
requests for borrowings shall be made, subject to the terms and conditions of
this Agreement and subject further to the terms of Section 2.5(c) hereof, by
telephonic or facsimile request of any Borrower. Agent may rely upon any and all
telephonic, facsimile and written requests purported to be made by any Borrower
through any of its officers. Each such written notice shall be irrevocable and
shall be effective only if received by the Agent not later than 1:00 p.m.,
Philadelphia time, on the date which is: (a) in the case of each notice of
termination one Business Day prior to the date of the related termination, and
(b) in the case of a notice of borrowing or reduction, the Business Day on which
the requested borrowing or reduction is to be made, subject, as to borrowings
for which the LIBOR Rate is being selected, to the provisions of Section 2.8(c)
hereof.

     2.4  Fees.  (a) The Borrowers shall pay to the Agent, for the account of
          -----
each Lender in accordance with their Pro Rata Percentages, a commitment fee at
the rate of four-tenths of one percent (4/10%) per annum on the daily average
unused amount of the Revolving Loan Commitment I and at a rate of three-tenths
of one percent (3/10%) per annum on the daily average unused amount of the
Revolving Loan Commitment II (which in each case shall be calculated as the
applicable Revolving Loan Commitment minus all cash advances outstanding under
the related Revolving Loan on the date of such calculation) during each calendar
quarter for the period from the date hereof to and including the earlier of the
date on which the applicable Revolving Loan Commitment is terminated or the
applicable Commitment Termination Date. The commitment fee shall be payable
quarterly in arrears on the Quarterly Dates and on the earlier of the date the
applicable Revolving Loan Commitment is terminated or the applicable Commitment
Termination Date.

                                      -12-
<PAGE>

          (b) The Borrowers shall concurrently with the execution hereof, pay to
the Agent, for the account of each Lender in accordance with their Pro Rata
Percentages, an amendment fee in the aggregate amount of $100,000.

          (c) The Borrowers shall pay to Agent, for its own account, a non-
refundable Agent Fee (the "Agent Fee") in such amount as to which Agent and
Borrowers may from time to time agree.

     2.5  Borrowings.
          -----------

          (a) Except as otherwise provided in subparts (b), (c) and (e) below,
upon receiving a request for a cash Advance in accordance with Section 2.3
hereof, Agent shall prior to 2:00 p.m. or as soon as reasonably practical
thereafter notify all Lenders of the request. Each Lender shall advance its
applicable Pro Rata Percentage of the requested Advance to Agent by remitting
federal funds, immediately available, to Agent pursuant to Agent's instructions
prior to 3:00 p.m. Philadelphia time or as soon as is reasonably practicable
thereafter on the date of such notice. Subject to the satisfaction of the terms
and conditions hereof, and receipt by the Agent of all required funds from the
other Lenders, Agent shall make the requested Advance available to the Borrowers
by crediting such amount to SSI's operating account with Agent, or to such other
account as SSI may from time to time designate to Agent, as soon as is
reasonably practicable thereafter on the day on which such Advance was
requested.

          (b) In lieu of the foregoing, Agent may, in its discretion (and
without any obligation to do so or continue to do so), fund the Pro Rata
Percentage of an Advance (including any cash Revolving Loan I Advance to
reimburse Issuer for unreimbursed draws under a Letter of Credit) on behalf of
any one or more Lenders (unconditionally and absolutely obliging such affected
Lender to reimburse Agent in full without deduction or setoffs for its portion
of such Advance) with a settlement among Lenders on the following Business Day
or under such other settlement procedures as Agent and Lenders may mutually
agree upon from time to time.

          (c) In lieu of the funding procedure set forth in subparts (a) and (b)
above, Agent hereby establishes for the Borrower an interim line of credit
(herein, the "Swing Line") under which Agent will, for its own account except as
otherwise set forth in this Section 2.5(c), fund cash Revolving Loan I Advances
under the Revolving Loan I, subject to the following terms and conditions:

               (i)    all cash Revolving Loan I Advances, so long as the same do
                      not exceed $15,000,000 in the aggregate at any time
                      outstanding, shall be made from the Swing Line instead of
                      the Revolving Loan I;

               (ii)   principal outstanding under the Swing Line will accrue
                      interest at the Agent's Prime Rate as otherwise set forth
                      in Section 2.8 (a) hereof, which interest shall, except as
                      provided in subpart (vii) below, be entirely for Agent's
                      own account;

               (iii)  all principal payments made by Borrower on account of the
                      Revolving Loan I shall be applied first to principal
                      outstanding under the Swing Line prior to application
                      thereof to the principal of the Revolving Loan I;

               (iv)   if there is neither any Advance under nor repayment of
                      principal on account of the Swing Line for seven (7)
                      consecutive Business Days, the unpaid principal of the
                      Swing Line as of the expiration of such seven (7) Business
                      Day period shall be funded by Banks

                                      -13-
<PAGE>

                      under the Revolving Loan I in accordance with subpart (a)
                      or (b) above, as the case may be;

               (v)    the Swing Line will be advanced pursuant to the procedures
                      set forth in and will otherwise be subject to the terms of
                      the Working Cash Agreements referred to in Section 4.2
                      hereof;

               (vi)   except as otherwise specifically set forth in this subpart
                      (c), Advances under the Swing Loan are subject to the same
                      terms and conditions of this Agreement which are
                      applicable to the Revolving Loan I and shall be deemed to
                      be "Obligations" and "Secured Obligations" of the
                      Borrowers for all purposes of this Agreement, and in no
                      event will the outstanding principal of the Swing Line,
                      when taken together with the outstanding principal of the
                      Revolving Loan I (including the face amount of Letters of
                      Credit and outstanding Reimbursement Obligations), exceed
                      the Revolving Loan Commitment I; and

               (vii)  immediately upon the making by Agent of each cash Advance
                      under the Swing Line (each such advance being herein
                      called a "Swing Loan"), Agent is deemed to have granted to
                      each Lender, and each Lender is hereby deemed to have
                      acquired, an undivided participating interest (without
                      recourse to or warranty by Agent), in accordance with each
                      such Lender's respective Pro Rata Percentage, in all of
                      Agent's rights and liabilities with respect to such Swing
                      Loan. In the event that the Obligations are accelerated
                      incident to an Event of Default, Agent shall promptly
                      notify each Lender of the unpaid principal balance of all
                      Swing Loans and all of such Lender's participation therein
                      based on such Lender's Pro Rata Percentage. Each Lender
                      shall make available to Agent an amount equal to its
                      respective participation in same day funds, at the office
                      of Agent specified in such notice, not later than 1:00
                      p.m. (Philadelphia time) on the Business Day after the
                      date notified by Agent. In the event that any Lender fails
                      to make available to Agent the amount of such Lender's
                      participation based on such Lender's Pro Rata Percentage
                      in such Swing Loans, Agent shall be entitled to recover
                      such amount on demand from such Lender together with
                      interest at the Fed Funds Rate for one (1) Business Day
                      and thereafter at two (2) percentage points above the
                      Agent's Prime Rate. Agent shall distribute to each other
                      Lender which has paid all amounts payable by it under this
                      subpart (c) with respect to any Swing Loans, such other
                      Lender's share, based on such Lender's Pro Rata
                      Percentage, of all payments received by Agent from
                      Borrower in payment of such Swing Loans, when such
                      payments are received.

          (d) Neither Agent nor any other Lender shall be obligated, for any
reason whatsoever, to advance the share of any other Lender. If such
corresponding amount is not made available to Agent by such Lender on the date
the Advance is to be made and Agent elects (at its discretion, without any
obligation to do so) to make such Lender's share of the Advance (including any
cash Revolving Loan I Advance to reimburse Issuer for unreimbursed draws under a
Letter of Credit), Agent shall be entitled to recover such amount on demand from
such Lender, together with interest in respect of each day during the period
commencing on the date such amount was made available to the Borrowers (or on
that date Agent required such funds to

                                      -14-
<PAGE>

be advanced pursuant to the settlement procedures established by Agent) and
ending on (but excluding) the date Agent recovers such amount, at a per annum
rate equal to the Fed Funds Rate for the first Business Day and thereafter at
two (2) percentage points above the Agent's Prime Rate. Agent shall also be
entitled to recover any and all losses and damages (including without
limitation, attorneys' fees) from any Lender failing to so advance upon demand
of Agent. Agent may set off the obligations of a Lender under this paragraph
against any distributions or payments of the Obligations which Agent would
otherwise make available to such Lender. To the extent any Lender fails to
provide or delays providing its respective Pro Rata Percentage of any requested
Advance, such Lender's Pro Rata Percentage of all payments of the Obligations
(but not its Pro Rata Percentage of Advances required to be funded by such
Lender) shall decrease to reflect the actual percentage which its actual
outstanding Advances bears to the total outstanding Advances of all Lenders.

     2.6  Use of Proceeds of Loans.
          -------------------------

     The proceeds of the Revolving Loans shall be used solely for general
corporate purposes, including for acquisition of Equity Interests subject to the
limitations set forth in Section 6.6 hereof.

     2.7  Payment of Loan.
          ----------------

          (a) Unless sooner accelerated pursuant to the terms hereof, the
applicable Revolving Loan shall be due and payable on the applicable Commitment
Termination Date. Borrowers will, on the Commitment Termination Date I, provide
Bank with cash collateral in an amount equal to 105% of the face amount of all
issued and outstanding Letters of Credit issued under this Agreement.

          (b) Except to the extent otherwise set forth in this Agreement, all
payments of principal and of interest on the Revolving Loans, and all other fees
and charges and any other Obligations of Borrowers hereunder, shall be made to
Agent at its Principal Office, in United States dollars, in immediately
available funds, not later than 1:00 p.m. Philadelphia time on the date on which
such payment is due. Agent and each Lender, on behalf of all Lenders, shall have
the unconditional right and discretion to charge any Borrower's operating
account with any such respective institution for all of Borrowers' Obligations
as they become due from time to time under this Agreement including without
limitation, interest, principal, fees and reimbursement of expenses.
Alternatively, Agent may in its discretion (and Borrowers hereby authorize Agent
to) direct the Lenders to make a cash Advance under the applicable Revolving
Loan (subject to the terms and provisions of this Agreement) in a sum sufficient
to pay all interest accrued and payable on the Obligations during the
immediately preceding month and to pay all costs, fees and expenses owing
hereunder.

     2.8  Interest.
          ---------

          (a) Subject to the provisions of subsection (c) hereof and subject
further to the provisions of Section 2.5(c)(ii), the Borrowers shall pay
interest on the unpaid principal amount of each Advance for the period
commencing on the date of such Advance until such Advance shall be paid in full,
at a rate per annum equal to Agent's Prime Rate. Notwithstanding the foregoing,
the Borrowers shall pay interest on any Advance, and on any other amount payable
by the Borrowers hereunder (including, to the extent permitted by law, interest)
which shall not be paid in full when due (whether at stated maturity, by
acceleration or otherwise, and including all reimbursement obligations on
Letters of Credit which are not immediately repaid from an Advance or otherwise)
for the period commencing on the due date thereof until the payment in full at
the Post-Default Rate. Except as provided in the next sentence, accrued interest
on the Loans shall be payable (i) monthly in arrears within 10 days of
Borrowers' receipt of a bill

                                      -15-
<PAGE>

therefor, and (ii) on the earlier of the date the applicable Revolving Loan
Commitment is terminated or the applicable Commitment Termination Date. Interest
payable at the Post-Default Rate shall be payable from time to time on demand of
the Agent. Interest shall continue to accrue and be paid at the applicable rate
provided herein even after Default, an Event of Default, entry of judgment
against any or all of the Borrowers or the commencement of any bankruptcy,
reorganization or insolvency proceeding, and any such judgment entered in
connection with the enforcement hereof or the collection of the Obligations
shall earn interest at the Post-Default Rate.

          (b) Notwithstanding any provision herein or in the Notes, the total
liability for payments of interest, or in the nature of interest, shall not
exceed the limits imposed by any applicable laws. If the terms of this Agreement
or the Security Documents, the Notes, or any other agreement or instrument
entered into in connection herewith require or shall require Borrowers to pay
interest in excess of amounts allowed by law, the rate of interest payable shall
be reduced immediately, without action by Lenders or Agent, to the applicable
maximum rate, and any excess payment made by Borrowers at any time shall be
immediately and automatically applied to the unpaid balance of the outstanding
principal due hereunder and not to the payment of interest. In the event of
acceleration of sums due hereunder, the total charges for interest and in the
nature of interest shall not exceed the maximum allowed by law, and any excess
portions of such charges which may have been prepaid and cannot be applied to
repayment of principal shall be refunded to Borrowers. Borrowers agree that in
determining whether or not any interest payable under this Agreement, the Notes
or the Security Documents exceeds the highest applicable rate permitted by law,
any non-principal payment including, without limitation, fees, costs, Post-
Default Rate and late charges, shall be deemed to the extent permitted by law to
be an expense, fee or penalty not deemed interest by law.

          (c)  (i)  As used in this Section 2.8(c), the following terms shall
have the following meanings:

                    (A) "Good Business Day" means any day when both Agent and
                         -----------------
banks in London, England are open for business.

                    (B) "LIBOR Rate" means for any day during each Rate Period
                        ------------
(a) the per annum rate of interest (computed on a basis of a year of 360 days
and actual days elapsed) determined by Agent as being the composite rate
available to Agent at approximately 11:00 a.m., London time in the London
Interbank Market, as referenced by Telerate (page 3750), in accordance with the
usual practice in such market, for the Rate Period elected by Borrowers, in
effect two (2) Good Business Days prior to the funding date for a requested
LIBOR Rate advance for deposits of dollars in amounts equal (as nearly as may be
estimated) to the amount of the LIBOR Rate advance which shall then be loaned by
the Lenders to Borrowers as of the time of such determination, as such rate (the
"Base Rate") may be adjusted by the reserve percentage applicable during the
Rate Period in effect (or if more than one such percentage shall be applicable,
the daily average of such percentages for those days in such Rate Period during
which any such percentage shall be so applicable) under regulations issued from
time to time by the Board of Governors of the Federal Reserve System (or any
successor) for determining the maximum reserve requirement (including, without
limitation, any emergency, supplemental or other marginal reserve requirement)
for the Agent with respect to liabilities or assets consisting of or including
"Eurocurrency Liabilities" as such term is defined in Regulation D of the Board
of Governors of the Federal Reserve System, as in effect from time to time,
having a term equal to such Rate Period ("Eurocurrency Reserve Requirement"),
plus (b) 1.25 percentage points. Such reserve adjustment shall be effectuated by
----
calculating, and the LIBOR Rate shall be equal to, (a) the quotient of (i) the
Base Rate divided by (ii) one minus the Eurocurrency Reserve Requirement, plus
                                                                          ----
(b) 1.25 percentage points.

                    (C) "Notification" means telephonic notice (which shall be

made not less than one (1) Business Day prior to the requested date of
quotation, shall apply to some portion of the principal amount of either of the
Revolving Loans in accordance with the provisions of this Section 2.8(c), which
notice shall be given no later than 11:00 a.m. Philadelphia time, on the day
which is at least 2 Business Days prior to the Business Day on which such
election is to become effective, which notice shall specify (i) that the LIBOR
Rate option is being selected; (ii) the principal amount of cash Advances under

                         -----------
the Loans for which Borrowers elect the LIBOR Rate the period of time for which
such rate shall apply to such principal portion. Rate periods for principal
earning interest at the LIBOR Rate shall be for periods of 30, 60, 90 or 180
days and for no other length of time, provided, that, no Rate Period may end on
other than a Business Day or after the applicable Commitment Termination Date.

              (ii)  (A)  Subject to the terms of this Section 2.8 (c) (ii), by
giving Notification, Borrowers may request to have all or a portion of the
outstanding principal of cash Advances under the Loans (other than Swing Loans)
as hereinafter permitted earn interest at the LIBOR Rate as follows: (1) with
respect to the principal amount of any cash Advance under the Loans, from the
date of such Advance until the end of the Rate Period specified in the
Notification; and/or (2) with respect to the principal amount of any portion of
cash Advances under the Loans outstanding and earning interest at the LIBOR Rate
at the time of the Notification related to such principal amount, from the
expiration of the then current Rate Period related to such principal amount
until the end of the Rate Period specified in the Notification; and/or (3) with
respect to all or any portion of the principal amount of cash Advances under the
Loans outstanding and earning interest at the Prime Rate at the time of

provisions of this Agreement, the Prime Rate and the LIBOR Rate may apply

which any LIBOR Rate election may be made shall be $5,000,000, and (5) that
Agent shall have the right to terminate any Rate Period, and the interest rate
applicable thereto, prior to maturity of such Rate Period, if Agent determines
in good faith (which determination shall be conclusive) that continuance of such
interest rate has been made unlawful by any Law to which any Lender may be
subject, in which event the principal to which such terminated Rate Period
relates thereafter shall earn interest at the Prime Rate.

                    (C) After expiration of any Rate Period, any principal
portion corresponding to such Rate Period which has not been converted or
renewed in accordance with this Section 2.8(c) (ii) shall earn interest
automatically at the Prime Rate from the date of expiration of such Rate Period
until paid in full, unless and until the Borrowers request and Agent approves a
conversion to the LIBOR Rate in accordance with this Section 2.8. With respect
to any cash Advances (whether an advance of new funds or an already outstanding

                                      -17-
<PAGE>

amount), if Borrowers fail to request the LIBOR Rate option by giving Bank a
Notification, or if Agent fails to approve such request when made, such
principal amount shall earn interest at the Prime Rate.

                    (D) Borrowers shall indemnify Lenders against any and all
loss or expense (including loss of margin) which any Lender has sustained or
incurred as a consequence of (a) any payment of any principal amount earning

such payment is consented to by Agent, unless Agent shall have expressly waived
such indemnity in writing); (2) any attempt by a Borrower to revoke in whole or
part any Notification given pursuant to this Agreement; (3) any attempt by
Borrowers to convert or renew any principal amount earning interest at the LIBOR
Rate on a day other than the last day of the corresponding Rate Period (whether
or not such conversion or renewal is consented to by Agent, unless Agent shall
have expressly waived such indemnity in writing); or (4) any breach of or
default by any Borrower.

          ------

     Contemporaneously herewith, Borrowers shall execute and deliver to each
Lender their Notes in the principal amount of such Lender's Pro Rata Share of

Borrowers shall, prior to the occurrence of an Event of Default and provided
that Borrowers are in full compliance with the Collateral Coverage Base and the
Borrowing Base, have the right to designate the applicable Revolving Loan to
which principal payments are to be applied; after an Event of Default and/or
should Borrowers not be in compliance with the Collateral Coverage Base or the
Borrowing Base, principal shall be applied to either of the Loans and in any
order as Agent shall determine in its discretion.

participant shall be entitled, at its option, and for the ratable benefit of all
Lenders, to offset balances held by it at any of its offices against any

due (regardless

                                      -18-
<PAGE>

repayment is made pursuant to acceleration upon or after an Event of Default,
demand by Agent otherwise made under this Agreement, by reason of an application

other reason), Borrowers shall, together with such repayment, pay to Agent, for

of the close of the last previous trading day. Any determination of the value of
the Collateral Coverage Securities by the Agent through its brokerage services
shall be conclusive and binding on Borrowers absent manifest error. Borrowers
may sell Collateral Coverage Securities in accordance with the terms of the
Pledge Agreement so long as after giving effect to any such sale, Borrowers are
not in violation of the Collateral Coverage Base or the Borrowing Base and the
proceeds thereof shall be paid over to Agent as provided in the Pledge

Subsidiary (other than another Borrower).

          (b) There are no jurisdictions other than as set forth on Exhibit 3.1
hereto in which the character of the properties owned or proposed to be owned by
the Borrowers or in which the transaction of the business of any of the
Borrowers as now conducted or as proposed to be conducted requires or will
require any Borrower to qualify to do business in any such other jurisdiction
where the failure to do so would have a Material Adverse Effect on such
Borrower.

     3.2  Power, Authority, Consents.
          ---------------------------

     Each Borrower has the power to execute, deliver and perform this Agreement,

governmental authority, bureau or agency, domestic or foreign, or certificate of
incorporation or bylaws of any Borrower or create (with or without the giving of
notice or lapse of time, or both) a default under or breach of any agreement,
bond, note or indenture to which any Borrower is a party, or by which it is
bound or any of its properties or assets is affected, or result in the

which are subject to the provisions of Title IV of ERISA (any such plans which
have been or may hereafter be adopted or assumed by the Borrowers are

described in Section 4043(b) (3) of ERISA; (2) a termination or partial
termination; or (3) a merger or consolidation with, or transfer of assets to,
another plan. The Borrowers have no outstanding liability to the PBGC for reason
of any such Reportable Event, and the Borrowers have not received any notice
from the PBGC that any of the Plans should be terminated or from the Secretary
of the Treasury that any partial or full termination of any of the Plans has

          (d) No termination proceedings with respect to any of the Plans have
been commenced and have not yet been concluded.

with any available remedy and in any order.

Article 8.  The Agent.
            ----------

     As between Agent, on one hand, and Lenders, on the other hand, Agent and
each Lender, who are now or shall become parties to this Agreement, agree as
follows:

     8.1  Appointment and Authorization. Each Lender, and each subsequent holder
          -----------------------------
of any of the Notes by its acceptance thereof, hereby irrevocably appoints and
authorizes Agent to take such action on its behalf and to exercise such powers
under this Agreement as are delegated to Agent by the terms hereof, together
with such powers as are reasonably incidental thereto. Subject to the provisions
of this Agreement, Agent will handle all transactions relating to the Loans and
all other Obligations, including, without limitation, all transactions with
respect to Letters of Credit, this Agreement, the Loan Documents and all related
documents, in accordance with its usual banking practices. Except as otherwise
expressly provided herein, Borrowers are hereby authorized by Lenders to deal
solely with Agent in all transactions which affect Lenders under this Agreement
and the Loan Documents. The rights, privileges and remedies accorded to Agent
hereunder shall be exercised by Agent on behalf of all of the Lenders.

     8.2  General Immunity.  In performing its duties as Agent hereunder, Agent
          -----------------
will take the same care as it takes in connection with loans in which it alone
is interested. Subject to Section 8.6 of this Agreement, neither Agent nor any
of its directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them hereunder or in connection herewith
except such action or omission to the extent caused from its or their own gross
negligence or willful misconduct unless such action was taken or omitted to be
taken by Agent at the direction of Majority Lenders.

     8.3  Consultation with Counsel.  Agent may consult with legal counsel and
          --------------------------
any other professional advisors or consultants deemed necessary or appropriate
and selected by Agent and shall not be liable for any action taken or suffered
in good faith by it in accordance with the advice of such counsel.

     8.4  Documents.  Agent shall not be under a duty to examine into or pass
          ----------
upon the effectiveness, genuineness or validity of this Agreement or any of the
Notes or any other instrument or document furnished pursuant hereto or in
connection herewith, and Agent shall be entitled to assume that the same are
valid, effective and genuine and what they purport to be. In addition Agent
shall not be liable for failing to make any inquiry concerning the accuracy,
performance or observance of any of the terms, provisions or conditions of such
instrument or document. Agent shall furnish to Lenders copies of all notices and
financial statements received from Borrowers hereunder.

     8.5  Rights as a Lender.  With respect to its applicable Pro Rata
          -------------------
Percentage of the Loans, PNC Bank National Association shall have the same
rights and powers hereunder as any other Lender and may exercise the same as
though it were not Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include Agent in its individual capacity as a
"Lender". Subject to the provisions of this Agreement, Agent may accept deposits
from,

                                      -37-
<PAGE>

lend money to and generally engage in any kind of banking or trust business with
Borrowers and their affiliates and Subsidiaries as if it were not Agent.

     8.6  Responsibility of Agent.  It is expressly understood and agreed that
          ------------------------
the obligations of Agent hereunder are only those expressly set forth in this
Agreement and that Agent shall be entitled to assume that no Default or Event of
Default has occurred and is continuing, unless Agent has actual knowledge of
such fact. Except to the extent Agent is required by Lenders pursuant to the
express terms hereof to take a specific action, Agent shall be entitled to use
its discretion with respect to exercising or refraining from exercising any
rights which may be vested in it by, or with respect to taking or refraining
from taking any action or actions that it may be able to take under or in
respect of, this Agreement and the Loan Documents. Agent shall incur no
liability under or in respect of this Agreement and the Loan Documents by acting
upon any notice, consent, certificate, warranty or other paper or instrument
believed by it to be genuine or authentic or to be signed by the proper party or
parties, or with respect to anything that it may do or refrain from doing in the
reasonable exercise of its judgment, or that may seem to it to be necessary or
desirable under the circumstances. It is agreed among Agent and Lenders that
Agent shall have no responsibility to carry out audits or otherwise examine the
books and records or properties of Borrowers, except as Agent in its sole
discretion deems appropriate or as otherwise expressly required hereunder. The
relationship between Agent and each Lender is and shall be that of agent and
principal only and nothing herein shall be construed to constitute Agent a joint
venturer with any Lender, a trustee or fiduciary for any of Lenders or for the
holder of a participation therein nor impose on Agent duties and obligations
other than those set forth herein.

     8.7  Collections and Disbursements.
          ------------------------------

          (a)  Agent will have the right to collect and receive all payments of
the Obligations, and to collect and receive all reimbursements for draws made
under the Letters of Credit, together with all fees, charges or other amounts
due under this Agreement and the Loan Documents, and Agent will remit to each
Lender, according to its applicable Pro Rata Percentage, all such payments
actually received by Agent (subject to any required clearance procedures) in
accordance with the settlement procedures established by Agent from time to
time, provided that each Lender acknowledges that the Agent Fee and issuance and
other administrative fees for Letters of Credit and interest on the Swing Line
may be retained by Agent for its own account.

          (b)  If any such payment, other than the Agent Fee, received by Agent
is rescinded or otherwise required to be returned for any reason at any time,
whether before or after termination of this Agreement and the Loan Documents,
each Lender will, upon written notice from Agent, promptly pay over to Agent its
Pro Rata Percentage of the amount so rescinded or returned, together with
interest and other fees thereon if also required to be rescinded or returned.

          (c)  All payments by Agent and Lenders to each other hereunder shall
be in immediately available funds. Agent will at all times maintain proper books
of account and records reflecting the interest of each Lender in the Revolving
Loans, in a manner customary to Agent's keeping of such records, which books and
records shall be available for inspection by each Lender at reasonable times
during normal business hours, at such Lender's sole expense. Agent may treat the
payees of any Revolving Loan Note as the holder thereof until written notice of
the transfer thereof shall have been received by Agent. In the event that any
Lender shall receive any payments in reduction of the Revolving Loans in an
amount greater than its applicable Pro Rata Percentage in respect of
indebtedness to Lenders evidenced hereby (including, without limitation amounts
obtained by reason of setoffs), such Lender shall hold such excess in trust for
                                                                   --------
Agent (on behalf of all other Lenders) and shall promptly remit to Agent such
excess amount so that the amounts received by each Lender hereunder shall at all
times be

                                      -38-
<PAGE>

in accordance with its applicable Pro Rata Percentage. To the extent necessary
for each Lender's actual percentage of all outstanding Advances to equal its
applicable Pro Rata Percentage, any Lender having a greater share of any
payment(s) than its applicable Pro Rata Percentage shall acquire a participation
in the applicable Pro Rata Percentage of the other Lenders as determined by
Agent.

     8.8  Indemnification.  Lenders hereby each indemnify Agent (and Issuer with
          ----------------
respect to Letters of Credit) ratably according to each Lender's Pro Rata
Percentage, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever that may be imposed on, incurred by or asserted
against Agent (or Issuer, as the case may be) in any way relating to or arising
out of this Agreement or any other Loan Document or any action taken or omitted
by Agent (or Issuer, as the case may be) under or related to this Agreement,
provided that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements to the extent resulting from Agent's (or Issuer's, as
the case may be) gross negligence or willful misconduct unless such action was
taken or omitted by Agent (or Issuer, as the case may be) at the direction of
the Majority Lenders.  Agent shall have the right to deduct, from any amounts to
be paid by Agent to any Lender hereunder, any amounts owing to Agent by such
Lender by virtue of this paragraph.

     8.9  Expenses.
          ---------

          (a)  All out-of-pocket costs and out-of-pocket expenses incurred by
Agent and not reimbursed on demand by Borrowers, in connection with the
amendment, administration, termination, work-out, forbearance and enforcement of
the Revolving Loans (including, without limitation, audit expenses, counsel fees
and expenditures to protect, preserve and defend Agent's and each Lender's
rights and interest under the Loan Documents) shall be shared and paid on demand
by Lenders pro rata based on their applicable Pro Rata Percentage.

          (b)  Agent may deduct from payments or distributions to be made to
Lenders such funds as may be necessary to pay or reimburse Agent for such costs
or expenses.

     8.10 No Reliance.  By execution of or joining in this Agreement, each
          ------------
Lender acknowledges that it has entered into this Agreement and the Loan
Documents solely upon its own independent investigation and is not relying upon
any information supplied by or any representations made by Agent. Each Lender
shall continue to make its own analysis and evaluation of Borrowers. Agent makes
no representation or warranty and assumes no responsibility with respect to the
financial condition of any Borrower, any obligor or any account debtor of any
Borrower; the accuracy, sufficiency or currency of any information concerning
the financial condition, prospects or results of operations of any Borrower; or
for sufficiency, authenticity, legal effect, validity or enforceability of the
Loan Documents. Agent assumes no responsibility or liability with respect to the
collectibility of the Obligations or the performance by Borrowers of any
obligation under the Loan Documents.

     8.11 Reporting.  During the term of this Agreement, Agent will, to the
          ---------
extent not required to be delivered by Borrowers to each Lender pursuant to the
other terms of this Agreement, promptly furnish each Lender with copies of all
financial statements and Borrowing Base Certificates of Borrowers to be
delivered to or obtained by Agent hereunder. Agent will immediately notify
Lenders when it receives actual knowledge of any Event of Default under the Loan
Documents.

     8.12 Removal of Agent.  Agent may resign at any time upon giving thirty
          -----------------
(30) days prior written notice thereof to Lenders and Borrowers. Agent may be
removed as Agent hereunder upon the written direction of such of the other
Lenders having 66.67% of the Pro Rata

                                      -39-
<PAGE>

Percentage of all Lenders other than Agent. Upon any resignation or removal of
Agent, the Lenders (exclusive of Agent) shall have the right to appoint a
successor Agent by majority vote of the other Lenders (based upon the Pro Rata
Percentages of the other Lenders). Upon the acceptance of the appointment as a
successor Agent hereunder by such successor Agent, such successor Agent shall
thereupon succeed to and become vested with all rights, powers, obligations and
duties of the retiring Agent and the retiring Agent shall be discharged from its
duties and obligations hereunder.

     8.13 Action on Instructions of Lenders.  With respect to any provision of
          ----------------------------------
this Agreement, or any issue arising thereunder, concerning which Agent is
authorized to act or withhold action by direction of Lenders (including the
Majority Lenders), Agent shall in all cases be fully protected in so acting, or
in so refraining from acting, hereunder in accordance with written instructions
signed by such Lenders. Such instructions and any action taken or failure to act

of the Loan Documents and grant such indulgences, forbearances and other waivers
as it shall determine.

until paid in full before any thereof shall be applied against the principal
balance of the Other Credit Facilities.

the provisions of Section 8.15 hereof) and then any such waiver or consent shall

                        EXECUTIVE EMPLOYMENT AGREEMENT

     THIS AGREEMENT, dated March 13, 2000 is made and entered into by and
between CompuCom Systems, a Delaware corporation ("Employer"), and Anthony F.
Pellegrini, an executive employee of Employer ("Executive").

                                   Recitals

     A.   Executive is employed by Employer in an executive capacity and
Executive has agreed to continue as an employee of Employer pursuant to the
terms of this Agreement.

     B.   Employer desires that the Executive continue as an employee of
Employer in order to provide the necessary leadership and senior management
skills that are important to the success of Employer. Employer believes that
retaining the Executive's services as an employee of Employer and the benefits
of his business experience are of material importance to Employer and Employer's
shareholders.

                                   Agreement

     NOW, THEREFORE, in consideration of Executive's continued employment by
Employer and the mutual promises and covenants contained herein the receipt and
sufficiency of which is hereby acknowledged, Employer and Executive intend by

President of Sales.

     1.2  While employed hereunder, Executive shall obey the lawful directions
of the Board of Directors of Employer, or any duly authorized committee thereof,
and shall use his best efforts to promote the interests of Employer and to
maintain and to promote the reputation thereof. While employed hereunder,

<PAGE>

and obligations hereunder and such as may be assigned to or vested in him by the
Board of Directors of Employer, or any duly authorized committee thereof.

          1.3.  While this Agreement is in effect, Executive may from time to
time engage in any businesses or activities that do not compete directly and
materially with Employer, provided that such businesses or activities do not
materially interfere with his performance of the duties assigned to him in
compliance with this Agreement by the Board of Directors of Employer or any duly
authorized committee thereof. In any event, Executive is permitted to (i) invest
his personal assets as a passive investor in such form or manner as Executive
may choose in his discretion, (ii) participate in various charitable efforts,
and (iii) serve as a director or officer of any other entity or organization

          Section 2. Compensation and Benefits.

          2.1.  As compensation for services to Employer, Employer shall pay to
Executive, while this Agreement is in effect, a salary at a monthly rate of

Compensation Committee duly elected by the Board of Directors. The salary shall
be payable in equal bi-weekly installments, subject only to such payroll and
withholding deductions as may be required by law and other deductions applied
generally to employees of Employer for insurance and other employee benefit
plans. In addition, Executive shall be entitled to participate in the Company's
Management Incentive Compensation Plan ("MICP") at a rate of 50% of base salary.
This bonus will be subject to the parameters set forth by the Compensation
Committee each year and the amount of payment will be determined by such
Committee.

          2.2.  Upon Executive's furnishing to Employer customary and reasonable
documentary support (such as receipts or paid bills) evidencing costs and
expenses incurred by him in the performance of his services and duties hereunder
(including, without limitation, travel and entertainment expenses) and
containing sufficient information to establish the amount, date, place and
essential character of the expenditure, Executive shall be reimbursed for such
costs and expenses in accordance with Employer's normal expense reimbursement
policy.

          2.3.  Executive shall have the right to participate in medical, dental
insurance plans, 401(k) plan, life insurance or other plans existing in benefit
of executive officers of Employer.

          2.4.  Executive shall be entitled to such vacation (in no event less

organization of Employer, to keep available to Employer the services of present
employees and to preserve the business relations of Employer. Executive shall

upon his service and office.

     Section 4. Initial Term; Extensions of the Term.

     The term of this Agreement shall commence on the effective date hereof and

time upon at least thirty (30) days prior written notice to Employer.

     5.2. Employer may terminate Executive's employment under this Agreement at
any time, without prior notice, for "due cause" upon the good faith
determination by the Board of Directors of Employer that "due cause" exists for
the termination of the employment relationship. As used herein, the term "due
cause" shall mean any of the following events:

          (i)   any intentional misapplication by Executive of Employer's
     funds, or any other act of dishonesty injurious to Employer committed by
     Executive; or

          (ii)  Executive's conviction of a crime involving moral turpitude; or

          (iii) Executive's illegal use or possession of any controlled
     substance or chronic abuse of alcoholic beverages; or

          (iv)  Executive's breach, non-performance or non-observance of any of
     the terms of this Agreement if such breach, non-performance or non-
     observance shall continue beyond a period of ten (10) business days
     immediately after notice thereof by Employer to Executive; or

          (v)   any other action by the Executive involving willful and
     deliberate malfeasance or gross negligence in the performance of
     Executive's duties.

     5.3. In the event Executive is incapacitated by accident, sickness or
otherwise so as to render Executive mentally or physically incapable of
performing the services required under Section 1 of this Agreement for a period
of one hundred eighty (180) consecutive business days, and such incapacity is
confirmed by the written opinion of two (2) practicing
<PAGE>

medical doctors licensed by and in good standing in the state in which they
maintain offices for the practice of medicine, upon the expiration of such
period or at any time reasonably thereafter, or in the event of Executive's
death, Employer may terminate Executive's employment under this Agreement upon
giving Executive or his legal representative written notice at least thirty (30)
days' prior to the termination date. Executive agrees, after written notice by
the Board of Directors of Employer or a duly authorized committee or officer of
Employer, to submit to examinations by such practicing medical doctors selected
by the Board of Directors of Employer or a duly authorized committee or officer
of Employer.

     5.4   Employer may terminate Executive's employment under this Agreement
at any time for any reason whatsoever, even without "due cause," by giving a
written notice of termination to Executive, in which case the employment
relationship shall terminate immediately upon the giving of such notice.

     Section 6.  Effect of Termination.

     6.1   In the event the employment relationship is terminated (a) by
Executive upon thirty (30) days' written  notice pursuant to Subsection 5.1
hereof, (b) by Employer for "due cause" pursuant to Subsection 5.2 hereof, or
(c) by Executive breaching this Agreement by refusing to continue his employment
and failing to give the requisite thirty (30) days' written notice, all
compensation and benefits shall cease as of the date of termination, other
than: (i) those benefits that are provided by retirement and benefit plans and
programs specifically adopted and approved by Employer for Executive that are
earned and vested by the date of termination, (ii) Executive's pro rata annual
salary through the date of termination, and (iii) those benefits required by law
to be made available to terminating employees.

     6.2   If Executive's employment relationship is terminated pursuant to
Subsection 5.3 hereof due to Executive's incapacity or death, Executive (or, in
the event of Executive's death, Executive's legal representative) will be
entitled to those benefits tht are provided by retirement and benefits plans and
programs specifically adopted and approved by Employer for Executive that are
earned and vested at the date of termination and, even though no longer employed
by Employer, shall continue to receive salary compensation (payable in the
manner as prescribed in the second sentence of Subsection 2.1) for one year.

     6.3   If Employer (i) terminates the employment of Executive other than
pursuant to Subsection 5.2 hereof for "due cause" or other than for a disability
or death pursuant to Subsection 5.3 hereof, (ii) demotes the Executive to a
position below the level of the position described in Subsection 1.1, (iii)
decreases Executive's salary below the level or reduces the employee benefits
and perquisites below the level provided for by the terms of Section 2 hereof,
other than as a result of any amendment or termination of any employee and/or
executive benefit plan or arrangement, which amendment or termination is
applicable to all qualifying executives of Employer, then such action by
Employer, unless consented to in writing by Executive, shall be deemed to be a
constructive termination by Employer of Executive's employment (a "Constructive
Termination").  In the event of a Constructive Termination, at any time from the
start of this Agreement, March 13, 2000 through March 13, 2001, the Executive
shall be entitled to receive, the balance of payment remaining for the year
