Section 2.04, Sellers shall be in breach of this Agreement and shall be liable
to Buyer for any losses incurred by Buyer or its affiliates as a result of such
breach, including without limitation losses incurred in connection with any
decrease in the Closing Price of the Common Stock subsequent to the fifth
Exchange Business Day immediately preceding the Maturity Date.

     (c) The "EXCHANGE RATE" shall be determined by the Calculation Agent in
accordance with the following formula, and is subject to adjustment as a result
of certain events as provided in Article 7 and as provided in Section 6(i) of
the Pledge Agreement: (i) if the Maturity Price is less than the Threshold Price
but greater than $90.5917 (the "ISSUE PRICE"), the Exchange Rate shall be a
ratio (rounded upward or downward to the nearest 1/10,000th or, if there is not
a nearest 1/10,000th, to the next lower 1/10,000th) equal to the Issue Price
divided by the Maturity Price, (ii) if the Maturity Price is equal to or greater
than the Threshold Price, the Exchange Rate shall be a ratio (rounded upward or
downward to the nearest 1/10,000th or, if there is not a nearest 1/10,000th, to
the next lower 1/10,000th) equal to the Issue Price divided by the Threshold
Price and (iii) if the Maturity Price is equal to or less than the Issue Price,
the Exchange Rate shall be one (1). "THRESHOLD PRICE" means $111.4278, provided
that if for any period during the term of this Agreement a Rehypothecation
Unavailability (as defined in the Pledge Agreement) shall not have occurred or
shall not be continuing, then the Threshold Price shall be increased by an
amount equal to the product of $1.8118 and a fraction, the numerator of which
shall equal the number of days during the term of this Agreement on which a
Rehypothecation Unavailability shall not have occurred or shall not be
continuing and the denominator of which shall equal 1084.

     SECTION 2.04. Cash Settlement Option. Sellers may, upon written notice
delivered to Buyer at least 35 Exchange Business Days prior to the Maturity
Date, elect to deliver the Cash Settlement Amount to Buyer on the Maturity Date
by wire transfer of immediately available funds to an account designated by
Buyer, in lieu of the shares of Common Stock (or security entitlements in
respect thereof) to be delivered on the Maturity Date pursuant to Section
2.03(b).



                                    ARTICLE 3

                             TERMINATION BY SELLERS

     SECTION 3.01. Termination by Seller. Sellers may terminate this Agreement
in whole or in part upon 35 Exchange Business Days' prior written notice to
Buyer (the termination date specified in such notice, the "OPTIONAL TERMINATION
DATE"). If Sellers terminate this Agreement in whole, Sellers shall make a cash
payment, by wire transfer of immediately available funds to an account
designated by Buyer, to Buyer on the Optional Termination Date in an amount
equal to the Replacement Value (calculated in the manner

                                       6
<PAGE>   10

set forth in Section 8.01 as if the Optional Termination Date were the
Acceleration Date). If Sellers terminate this Agreement in part, Sellers shall
specify the number of shares of Common Stock with respect to which this
Agreement is to be terminated and (i) Sellers shall make a cash payment, by wire
transfer of immediately available funds to an account designated by Buyer, to
Buyer on the Optional Termination Date in an amount equal to the Replacement
Value (calculated in the manner set forth in Section 8.01 as if the Optional
Termination Date were the Acceleration Date, provided that for purposes of such
calculation, the Base Amount shall be deemed to be such number of shares of
Common Stock with respect to which this Agreement is to be terminated) and (ii)
the Base Amount shall be reduced by such number of shares of Common Stock with
respect to which this Agreement is to be terminated.

     to applicable bankruptcy, reorganization, insolvency, moratorium or similar
     laws affecting creditors' rights generally and subject, as to
     enforceability, to equitable principles of general application (regardless
     of whether enforcement is sought in a proceeding in equity or at law)).

          (e) No Acceleration Event or event that, with the giving of notice or
     the lapse of time or both, would constitute an Acceleration Event has
     occurred and is continuing and no such event would occur as a result of its
     entering into or

                                       8

     performing its obligations under this Agreement or (in the case of
     Subsidiary) the Pledge Agreement.

          (f) There is not pending or, to its knowledge, threatened against it
     or any of its affiliates any action, suit or proceeding at law or in equity
     or before any court, tribunal, governmental body, agency or official or any
     arbitrator that is likely to affect the legality, validity or
     enforceability against it of this Agreement or (in the case of Subsidiary)
     the Pledge Agreement or its ability to perform its obligations under this
     Agreement or (in the case of Subsidiary) the Pledge Agreement.

          (g) It is acting for its own account, and has made its own independent
     decision to enter into this Agreement and (in the case of Subsidiary) the
     Pledge Agreement and as to whether this Agreement and the Pledge Agreement
     are appropriate or proper for it based upon its own judgment and upon
     advice of such advisors as it deems necessary. It acknowledges and agrees
     that it is not relying, and has not relied, upon any communication (written
     or oral) of Buyer or any affiliate, employee or agent of Buyer with respect
     to the legal, accounting, tax or other implications of this Agreement and
     (in the case of Subsidiary) the Pledge Agreement and that it has conducted
     its own analyses of the legal, accounting, tax and other implications
     hereof and thereof; it being understood that information and explanations
     related to the terms and conditions of this Agreement or (in the case of
     Subsidiary) the Pledge Agreement shall not be considered investment advice
     or a recommendation to enter into this Agreement or (in the case of
     Subsidiary) the Pledge Agreement. It is entering into this Agreement and
     (in the case of Subsidiary) the Pledge Agreement with a full understanding
     of all of the terms and risks hereof and thereof (economic and otherwise)
     and is capable of evaluating and understanding (on its own behalf or
     through independent professional advice), and understands and accepts, the
     terms, conditions and risks. It is also capable of assuming (financially
     and otherwise), and assumes, those risks. It acknowledges that neither
     Buyer nor any affiliate, employee or agent of Buyer is acting as a
     fiduciary for or an advisor to it in respect of this Agreement or (in the
     case of Subsidiary) the Pledge Agreement.

          (h) It is not an "affiliate", within the meaning of Rule 144 under the
     Securities Act, of the Issuer. From the date three months prior to the date
     hereof until the Restriction Termination Date, Seller has not, without the
     written consent of Buyer, sold any shares of Common Stock (or security
     entitlements in respect thereof) or hedged (through swaps, options, short
     sales or otherwise) any long position in the Common Stock (or security
     entitlements in respect thereof), other than sales or hedges that would
     not, if aggregated with sales of a number of shares of Common Stock equal
     to the Base Amount, exceed the volume limits set forth in Rule 144(e) under
     the Securities Act for any three month period. Seller does not know or have
     any reason to believe that the Company has not complied with the reporting
     requirements contained in Rule 144(c)(1) under the Securities Act.

          (i) Delivery of shares of Common Stock (or security entitlements in
     respect thereof) by it pursuant to Section 2.03(b) or Section 8.01 will
     pass to Buyer title to such shares (or security entitlements) free and
     clear of any Liens or Transfer Restrictions, except for those created
     pursuant to the Pledge Agreement.

          (j) It has a valid business purpose for entering into this Agreement,
     and the transaction contemplated hereby is consistent with its overall
     investment strategy.

                        CONDITIONS TO BUYER'S OBLIGATIONS

     SECTION 5.01. Conditions. The obligation of Buyer to deliver the Purchase
Price on the Payment Date is subject to the satisfaction of the following
conditions:

          (a) The representations and warranties of each Seller contained in
     Article 4 and in the Pledge Agreement shall be true and correct as of the
     Payment Date.

          (b) The Pledge Agreement shall have been executed by the parties
     thereto, and Subsidiary shall have delivered to the Collateral Agent in
     accordance therewith the collateral required to be delivered pursuant to
     Section 1(b) thereof.

          (c) Sellers shall have performed all of the covenants and obligations
     to be performed by them hereunder and (in the case of Subsidiary) under the
     Pledge Agreement on or prior to the Payment Date.

          (d) There shall not have occurred, in the reasonable determination of
     Buyer, any material decrease in the public float or daily trading volume of
     the Common Stock.

          (e) Sellers shall have delivered to Buyer on or prior to the Payment
     Date an opinion of counsel acceptable to Buyer to the effect set forth in
     Annex A.



                                    ARTICLE 6

                                    COVENANTS

     SECTION 6.01. Taxes. Sellers shall pay any and all documentary, stamp,
transfer or similar taxes and charges that may be payable in respect of the
entry into this Agreement and the transfer and delivery of any Common Stock (or
security entitlements in respect thereof) pursuant hereto. Sellers further agree
to make all payments in respect of this Agreement free and clear of, and without
withholding or deduction for or on account of,

                                       10
<PAGE>   14

any present or future taxes, duties, fines, penalties, assessments or other
governmental charges of whatsoever nature (or interest on any taxes, duties,
fines, penalties, assessments or other governmental charges of whatsoever
nature) imposed, levied, collected, withheld or assessed by, within or on behalf
of (a) the United States or any political subdivision or governmental authority
thereof or therein having power to tax or (b) any jurisdiction from or through
which payment on the Agreement is made by the either Seller, or any political
subdivision or governmental authority thereof or therein having power to tax. In
the event such withholding or deduction is imposed, Sellers jointly and
severally agree to indemnify the Buyer for the full amount of such withholding
or deduction, as well as any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.

     SECTION 6.02. Forward Contract. Each Seller hereby agrees that: (i) it will
not treat this Agreement, any portion of this Agreement, or any obligation
hereunder as giving rise to any interest income or other inclusions of ordinary
income; (ii) it will not treat the delivery of any portion of the shares of
Common Stock (or security entitlements in respect thereof) or cash to be
delivered pursuant to this Agreement as the payment of interest or ordinary
income; (iii) it will treat this Agreement in its entirety as a forward contract
for the delivery of such shares of Common Stock (or security entitlements in
respect thereof) or cash; and (iv) it will not take any action (including filing
any tax return or form or taking any position in any tax proceeding) that is
inconsistent with the obligations contained in (i) through (iii).
Notwithstanding the preceding sentence, either Seller may take any action or
position required by law, provided that such Seller deliver to Buyer an
unqualified opinion of counsel, nationally recognized as expert in Federal tax
matters and acceptable to Buyer, to the effect that such action or position is
required by a statutory change or a Treasury regulation or applicable court
decision published after the date of this Agreement.

     SECTION 6.03. Notices. Each Seller will cause to be delivered to Buyer:

          (a) Immediately upon the occurrence of any Acceleration Event
     hereunder, notice of such occurrence; and

          (b) In case at any time prior to the Maturity Date such Seller or any
     officer of such Seller receives notice that any event requiring that an
     adjustment be calculated pursuant to Article 7 hereof shall have occurred
     or be pending, then such Seller shall promptly cause to be delivered to
     Buyer a notice identifying such event and stating, if known to such Seller,
     the date on which such event occurred or is to occur and, if applicable,
     the record date relating to such event. Such Seller shall cause further
     notices to be delivered to Buyer if such Seller or any officer of such
     Seller shall subsequently receive notice of any further or revised
     information regarding the terms or timing of such event or any record date
     relating thereto.

     SECTION 6.04. Further Assurances. From time to time from and after the date
hereof through the Maturity Date, each of the parties hereto shall use its
reasonable best efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things

                                       11
<PAGE>   15

necessary, proper and advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement in accordance with
the terms and conditions hereof, including (i) using reasonable best efforts to
remove any legal impediment to the consummation of such transactions and (ii)
the execution and delivery of all such deeds, agreements, assignments and
further instruments of transfer and conveyance necessary, proper or advisable to
consummate and make effective the transactions contemplated by this Agreement in
accordance with the terms and conditions hereof.

     SECTION 6.05. Actions That Could Cause Either Seller to Become an
Affiliate. Each Seller shall notify Buyer immediately of its intention to (i)
purchase Common Stock (or security entitlements in respect thereof) or any other
equity security of the Issuer in an amount that would cause such Seller to
become the beneficial owner, directly or indirectly, of more than three percent
of the outstanding shares of any equity security of the Issuer, (ii) accept a
position as an officer or director of the Company, (iii) take any action that
would cause such Seller to possess, directly or indirectly, the power to direct
or cause the direction of the management and policies of the Issuer, whether by
ownership of voting securities, by contract or otherwise, or (iv) take any other
action that could reasonably be expected to result in such Seller becoming an
"affiliate," within the meaning of Rule 144 under the Securities Act, of the
Issuer. Each Seller shall not take any such action unless a period of fifteen
Business Days shall have elapsed after receipt of such notice by Buyer and Buyer
shall not have objected in writing to such action during such period.

     SECTION 6.06. Securities Contract. The parties hereto recognize that the
Collateral Agent is a "financial institution" within the meaning of Section
101(22) of Title 11 of the United States Code (the "BANKRUPTCY CODE") and is
acting as agent and custodian for Buyer in connection with this Agreement and
that Buyer is a "customer" of the Collateral Agent within the meaning of said
Section 101(22). The parties hereto further recognize that this Agreement is a
"securities contract," as such term is defined in Section 741(7) of the
Bankruptcy Code, entitled to the protection of Section 555 of the Bankruptcy
Code.

     SECTION 6.07. Sales of Common Stock. Seller agrees that it shall not,
without the prior written consent of Buyer, sell any shares of Common Stock (or
security entitlements in respect thereof) or hedge (through swaps, options,
short sales or otherwise) any long position in the Common Stock (or security
entitlements in respect thereof), other than sales or hedges that would not, if
aggregated with sales of a number of shares of Common Stock equal to the Base
Amount, exceed the volume limits set forth in Rule 144(e) under the Securities
Act for any three month period, until the Restriction Termination Date.

                                    ARTICLE 7

                                   ADJUSTMENTS

     SECTION 7.01. Dilution Adjustments. (a) Following the declaration by the
Issuer of the terms of any Potential Adjustment Event occurring prior to the
Maturity Date, the

                                       12
<PAGE>   16

Calculation Agent will determine whether such Potential Adjustment Event has a
diluting or concentrative effect on the theoretical value of the Common Stock
and, if so, will (i) make the corresponding adjustment, if any, to any one or
more of the Base Amount, the Exchange Rate, the Threshold Price, the Issue
Price, the Maturity Price, the Cash Settlement Amount, any Closing Price and any
other variable relevant to the exercise, settlement or payment terms hereof or
of the Pledge Agreement as the Calculation Agent determines appropriate to
account for that diluting or concentrative effect and (ii) determine the
effective date of the adjustment. The Calculation Agent may (but need not)
determine the appropriate adjustment by reference to the adjustment in respect
of such Potential Adjustment Event made by an options exchange to options on the
Common Stock traded on that options exchange.

     (b) For these purposes, "POTENTIAL ADJUSTMENT EVENT" means any of the
following:

          (i) a subdivision, consolidation or reclassification of shares of
     Common Stock (which does not constitute a Reorganization Event), or a free
     distribution or dividend of any shares of Common Stock to existing holders
     of Common Stock by way of bonus, capitalization or similar issue;

          (ii) a distribution or dividend to existing holders of Common Stock of
     (A) shares of Common Stock, or (B) other share capital or securities
     granting the right to payment of dividends and/or the proceeds of
     liquidation of the Company equally or proportionately with such payments to
     holders of Common Stock, or (C) other types of securities, rights or
     warrants or other assets, in any case for payment (cash or other) at less
     than the prevailing market price as determined by the Calculation Agent;

          (iii) a cash dividend;

          (iv) a call by the Issuer in respect of shares of Common Stock that
     are not fully paid;

          (v) a repurchase by the Issuer of shares of Common Stock, whether out
     of profits or capital and whether the consideration for such repurchase is
     cash, securities or otherwise; or

          (vi) any other similar event that may have a diluting or concentrative
     effect on the theoretical value of the Common Stock.

     Without limiting the foregoing, the parties acknowledge that the
Calculation Agent will make adjustments to the Base Amount, the Threshold Price,
the Issue Price and any other variable relevant to the exercise, settlement or
payment terms hereof or of the Pledge Agreement as the Calculation Agent
determines appropriate to account for the value of all cash dividends (ordinary
or extraordinary) with respect to the Common Stock.


                                       13
<PAGE>   17


     (c) Notwithstanding the foregoing, in the event of a distribution of shares
of capital stock of a subsidiary of the Issuer that is a Publicly-Traded Entity
(a "SPIN-OFF") made to holders of shares of Common Stock, the Exchange Rate in
effect immediately prior to such Spin-Off shall be adjusted so that Buyer shall
thereafter be entitled to receive, on the Maturity Date, in addition to the
number of shares of Common Stock required to be delivered on the Maturity Date,
the number of shares of common stock of such Publicly-Traded Entity that Buyer
would have owned or been entitled to receive immediately following such Spin-Off
had the shares of Common Stock required to be delivered to Buyer hereunder on
the Maturity Date been delivered immediately prior to such Spin-Off. Following a
Spin-Off, "Original Common Stock" shall mean the common stock of the Issuer and
"New Common Stock" shall mean the common equity securities of the
Publicly-Traded Entity resulting from such Spin-Off.

     SECTION 7.02. Reorganization Events. In the event of (i) any consolidation
or merger of the Issuer with or into another entity (other than a merger or
consolidation in which the Issuer is the continuing corporation and in which the
Common Stock outstanding immediately prior to the merger or consolidation is not
exchanged for cash, securities or other property of the Issuer or another
corporation), (ii) any sale, transfer, lease or conveyance of the property of
the Issuer as an entirety or substantially as an entirety, (iii) any statutory
exchange of securities of the Issuer with another corporation (other than in
connection with a merger or acquisition) or (iv) any liquidation, dissolution or
winding up of the Issuer (any such event, a "REORGANIZATION EVENT"), then (A) if
the surviving or continuing corporation is a Publicly-Traded Entity, the
Exchange Rate in effect immediately prior to such Reorganization Event shall be
adjusted so that Buyer shall thereafter be entitled to receive, on the Maturity
Date, the number of shares of common stock of the Publicly-Traded Entity that
Buyer would have owned or been entitled to receive immediately following such
Reorganization Event had the shares of Common Stock required to be delivered to
Buyer hereunder on the Maturity Date been delivered immediately prior to such
Reorganization Event or (B) if the surviving or continuing corporation is not a
Publicly-Traded Entity, this Agreement shall terminate and Sellers shall make a
payment or delivery to Buyer as provided in Section 7.04.

     SECTION 7.03. Provisions Relating to Reorganization Events and Spin-Offs.
If a Reorganization Event occurs and clause (B) of Section 7.02 does not apply,
the surviving or continuing corporation shall be deemed to be the "Issuer" and
the common equity securities of such corporation shall be deemed to be the
"Common Stock". If a Spin-Off occurs, the Issuer and the Publicly-Traded Entity
resulting from the Spin-Off shall each be deemed to be the "Issuer" and the
Original Common Stock and the New Common Stock shall each be deemed to be the
"Common Stock". Following any Spin-Off, the Calculation Agent shall calculate
further adjustments pursuant to this Article 7 by applying the methodology set
forth in this Article 7 to both the Original Common Stock and the New Common
Stock.

     SECTION 7.04. Termination and Payment. Following termination of this
Agreement as a result of any Reorganization Event, the Calculation Agent shall
determine the Replacement Value in the manner provided in Section 8.01
(calculated, for purposes of this Section 7.04, as if the Termination Date were
the Acceleration Date, and

                                       14
<PAGE>   18

representing the fair replacement value (including both intrinsic and time
value) to Buyer of an agreement with terms that would preserve for Buyer the
economic equivalent of the payments and deliveries that Buyer and its affiliates
would, but for the occurrence of the Reorganization Event, have been entitled to
receive after the Termination Date hereunder). As promptly as reasonably
practicable after calculation of the Replacement Value, the Calculation Agent
shall deliver to Buyer and Sellers a notice (the "TERMINATION AMOUNT NOTICE")
specifying the Replacement Value. Not later than three Business Days following
delivery of a Termination Amount Notice, Sellers shall make a cash payment, by
wire transfer of immediately available funds to an account designated by Buyer,
to Buyer in an amount equal to the Replacement Value. Notwithstanding the
foregoing, to the extent that any Marketable Securities are received by holders
of Common Stock in such Reorganization Event, then in lieu of delivering cash as
provided in the immediately preceding sentence, Sellers may deliver Marketable
Securities with an equal value (as determine by the Calculation Agent in its
discretion in a commercially reasonable manner).



                                    ARTICLE 8

                                  ACCELERATION

     SECTION 8.01. Acceleration. If one or more of the following events (each an
"ACCELERATION EVENT") shall occur:

          (a) any legal proceeding shall have been instituted or any other event
     shall have occurred or condition shall exist that in Buyer's reasonable
     judgment could have a material adverse effect on the financial condition of
     either Seller or on either Seller's ability to perform such Seller's
     obligations hereunder, or that provides a reasonable basis to call into
     question the validity or binding effect of any agreement of such Seller
     hereunder or under the Pledge Agreement;

          (b) such Seller makes an assignment for the benefit of creditors,
     files a petition in bankruptcy, is adjudicated insolvent or bankrupt,
     petitions or applies to any tribunal for any receiver of or any trustee for
     such Seller or any substantial part of such Seller's property, commences
     any proceeding relating to such Seller under any reorganization,
     arrangement, readjustment of debt, dissolution or liquidation law or
     statute of any jurisdiction, whether now or hereafter in effect, or there
     is commenced against or with respect to such Seller or any substantial
     portion of Seller's property any such proceeding and an order for relief is
     issued or such proceeding remains undismissed for a period of 30 days;

          (c) at any time, any representation made or repeated or deemed to have
     been made or repeated by either Seller under this Agreement or the Pledge
     Agreement or any certificate delivered pursuant hereto or thereto would be
     incorrect or misleading if made or repeated as of such time in any respect
     that, in

                                       15
<PAGE>   19

     the reasonable judgment of Buyer, would have a material adverse effect on
     Buyer in respect of the transactions contemplated hereby;

          (d) Sellers fail to deliver shares of Common Stock (or security
     entitlements in respect thereof) or cash on the Maturity Date as required
     by this Agreement;

          (e) such Seller fails to fulfill or discharge when due any of its
     other obligations, covenants or agreements under or relating to this
     Agreement or the Pledge Agreement (other than the obligation referred to in
     Section 8.01(d)), and such failure remains unremedied for 30 days following
     notice from Buyer;

          (f) due to the adoption of, or any change in, any applicable law after
     the date hereof, or due to the promulgation of, or any change in, the
     interpretation by any court, tribunal or regulatory authority with
     competent jurisdiction of any applicable law after the date hereof, it
     becomes unlawful for either Seller to perform any absolute or contingent
     obligation to make payment or delivery hereunder or to comply with any
     other material provision of this Agreement or the Pledge Agreement;

          (g) in the reasonable judgement of the Calculation Agent, Buyer is
     unable to hedge Buyer's exposure to this Agreement in the ordinary course
     of Buyer's business through share borrowing arrangements because of the
     lack of sufficient shares of Common Stock being made available by lenders
     (it being understood that, at any time at which a Rehypothecation
     Unavailability (as defined in the Pledge Agreement) shall not have occurred
     and be continuing, there shall be deemed to be sufficient shares of Common
     Stock being made available by lenders);

          (h) there occurs a default under any indebtedness for money borrowed
     by either Seller or its subsidiaries (except CompuCom Systems, Inc. and
     Tangram Enterprise Solutions, Inc.), whether such indebtedness now exists
     or shall hereafter be created, which indebtedness, individually or in the
     aggregate, is in excess of $10,000,000 principal amount, which default
     shall constitute a failure to pay any portion of the principal of such
     indebtedness when due and payable after the expiration of any applicable
     grace or cure period with respect thereto or shall have resulted in such
     indebtedness becoming or being declared due and payable prior to the date
     on which it would otherwise have become due and payable;

          (i) a Collateral Event of Default within the meaning of the Pledge
     Agreement shall occur;

then, upon notice to Sellers from Buyer at any time following an Acceleration
Event, an "ACCELERATION DATE" shall occur, and Sellers shall become obligated to
deliver to Buyer immediately upon receipt of the Acceleration Amount Notice a
number of shares of Free Stock equal to the Acceleration Amount; provided that
if the Collateral Agent proceeds to

                                       16
<PAGE>   20

realize upon any collateral pledged under the Pledge Agreement and to apply the
proceeds of such realization as provided in paragraph second of Section 8(d)
thereof, then, to the extent of such application of proceeds, Sellers'
obligation to deliver Free Stock pursuant to this paragraph shall be deemed to
be an obligation to deliver an amount of cash equal to the aggregate Market
Value of such Free Stock on the Acceleration Date. The "ACCELERATION AMOUNT"
means the quotient obtained by dividing: (i) the Replacement Value by (ii) the
Market Value per share of the Common Stock on the Acceleration Date, provided
that the Acceleration Amount shall not be greater than the Base Amount.

     The "REPLACEMENT VALUE" means an amount determined by the Calculation Agent
representing the fair replacement value (including both intrinsic and time
value) to Buyer of an agreement with terms that would preserve for Buyer the
economic equivalent of the payments and deliveries that Buyer and its affiliates
would, but for the occurrence of the Acceleration Date, have been entitled to
receive after the Acceleration Date hereunder (taking into account any
adjustments pursuant to Section 7.01 or pursuant to Section 6(i) of the Pledge
Agreement that may have been calculated on or prior to the Acceleration Date),
including any loss of bargain, cost of funding or, without duplication, loss or
cost incurred as a result of Buyer terminating, liquidating, obtaining or
reestablishing any hedge or related trading position.

     As promptly as reasonably practicable after calculation of the Replacement
Value, the Calculation Agent shall deliver to either Seller and Buyer a notice
(the "ACCELERATION AMOUNT NOTICE") specifying the Acceleration Amount of shares
of Common Stock (or security entitlements in respect thereof) required to be
delivered by Sellers.

self-regulatory organization, each party hereto agrees to keep this Agreement
and the Pledge Agreement and the transactions contemplated hereby and thereby
confidential. In the event disclosure is permitted pursuant to the preceding
sentence, the disclosing party shall (i) provide prior notice of such disclosure
to the other party, (ii) use its best efforts to minimize the extent of such

benefit of CREDIT SUISSE FINANCIAL PRODUCTS ("SECURED PARTY"), and Secured
Party.

         WHEREAS, pursuant to the SAILS Mandatorily Exchangeable Securities
Contract (as amended from time to time, the "SECURITIES CONTRACT") dated as of
the date hereof among Pledgor, CSFP Capital, Inc., as Agent, and Secured Party,
Parent and Pledgor have jointly and severally agreed to sell and Secured Party
has agreed to purchase shares of common stock (the "COMMON STOCK") of Tellabs,
Inc., a Delaware corporation (the "ISSUER") (or security entitlements in respect
thereof), or cash in lieu thereof, subject to the terms and conditions of the
Securities Contract;

         WHEREAS, it is a condition to the obligations of Secured Party under
the Securities Contract that Pledgor, the Collateral Agent and Secured Party
enter into this Agreement and that Pledgor grant the pledge provided for herein;

         NOW, THEREFORE, in consideration of their mutual covenants contained
herein and to secure the performance by Parent and Pledgor of their obligations
under the Securities Contract and the observance and performance of the
covenants and agreements contained herein and in the Securities Contract, the
parties hereto, intending to be legally bound, hereby mutually covenant and
agree as follows:

         SECTION 1. The Security Interests. In order to secure the full and
punctual observance and performance of the covenants and agreements contained
herein and in the Securities Contract:

         (a) Pledgor hereby assigns and pledges to the Collateral Agent, as
agent of and for the benefit of Secured Party, and grants to the Collateral
Agent, as agent of and for the benefit of Secured Party, security interests in
and to, and a lien upon and right of set-off against, and transfers to the
Collateral Agent, as agent of and for the benefit of Secured Party, as and by
way of a security interest having priority over all other security interests,
with power of sale, all of its right, title and interest in and to (i) the

substitutions for such Pledged Items (including, without limitation, any
securities, instruments or other property delivered or pledged pursuant to
Section 5(a) or 6(b)); (iii) all income, proceeds and collections received or to
be received, or derived or to be derived, now or any time hereafter (whether
before or after the commencement of any proceeding under applicable bankruptcy,
insolvency or similar law, by or against Pledgor, with respect to Pledgor) from
or in connection with the Pledged Items (including, without limitation, any
shares of capital stock issued by the Issuer in respect of any Common Stock (or
security entitlements in respect thereof) constituting Collateral or any cash,
securities or other
<PAGE>   4
property distributed in respect of or exchanged for any Common Stock (or
security entitlements in respect thereof) constituting Collateral, or into which
any such Common Stock (or security entitlements in respect thereof) is
converted, in connection with any Merger Event, and any security entitlements in
respect of any of the foregoing); and (iv) all powers and rights now owned or
hereafter acquired under or with respect to the Pledged Items (such Pledged
Items, additions, substitutions, proceeds, collections, powers and rights being
herein collectively called the "COLLATERAL"). The Collateral Agent shall have
all of the rights, remedies and recourses with respect to the Collateral
afforded a secured party by the UCC, in addition to, and not in limitation of,
the other rights, remedies and recourses afforded to the Collateral Agent by
this Agreement.

         (b) On or prior to the Payment Date, Pledgor shall deliver to the
Collateral Agent in pledge hereunder Eligible Collateral consisting of a number
of shares of Common Stock (or security entitlements in respect thereof) equal to
the Base Amount, in the manner provided in Section 6(c).

         (c) In the event that the Issuer at any time issues to Pledgor in
respect of any Common Stock (or security entitlements in respect thereof)
constituting Collateral hereunder any additional or substitute shares of capital
stock of any class (or any security entitlements in respect thereof), Pledgor
shall immediately pledge and deliver to the Collateral Agent in accordance with
Section 6(c) all such shares and security entitlements as additional Collateral
hereunder.

         (d) The Security Interests are granted as security only and shall not
subject the Collateral Agent or Secured Party to, or transfer or in any way
affect or modify, any obligation or liability of Pledgor or the Issuer with
respect to any of the Collateral or any transaction in connection therewith.

UCC) with respect to any Collateral.

         (b) Other than financing statements or other similar or equivalent
documents or instruments with respect to the Security Interests, no financing
statement, security agreement or similar or equivalent document or instrument
covering all or any part of the Collateral is on file or of record in any
jurisdiction in which such filing or recording would be effective to perfect a
lien, security interest or other encumbrance of any kind on such Collateral.

         (c) All shares of Common Stock at any time pledged hereunder (or in

or its nominee in accordance with Section 6(c)(B), the Collateral Agent will

Stock remains so registered, perfected security interest therein, in respect of
which the Collateral Agent will have control, subject to no prior Lien and (ii)

<PAGE>   7
securities intermediary, perfected security interest in a securities entitlement

subject to no prior Lien.

         (e) No registration, recordation or filing with any governmental body,

this Agreement or necessary for the validity or enforceability hereof or for the
perfection or enforcement of the Security Interests.

         (f) Pledgor and Parent have not performed and will not perform any acts

         SECTION 4. Representations, Warranties and Agreements of the Collateral
Agent. The Collateral Agent represents and warrants to, and agrees with, Pledgor
and Secured Party that:

         (a) The Collateral Agent is a duly incorporated, validly existing and
in good standing under the laws of the jurisdiction of its incorporation, and
has all powers and all material governmental licenses, authorizations, consents
and approvals required to enter into, and perform its obligations under, this
Agreement.

         (b) The execution, delivery and performance by the Collateral Agent of
this Agreement have been duly authorized by all necessary action on the part of
the Collateral Agent and do not and will not violate, contravene or constitute a
default under any provision of applicable law or regulation or of the
constitutive documents of the Collateral Agent or of any material agreement,
judgment, injunction, order, decree or other instrument binding upon the
Collateral Agent.

         (c) This Agreement constitutes a valid and binding agreement of the
Collateral Agent enforceable against the Collateral Agent in accordance with its
terms.

         (d) Subject to Sections 6(i) and 6(j), the Collateral Agent has not and
will not enter into any agreement pursuant to which any person other than the
Pledgor, the Collateral Agent, the Secured Party or any securities intermediary
through whom any Collateral is held (but in the case of any such securities
intermediary only in respect of Collateral held through it) has or will have
control (within the meaning of Section 8-106 of the UCC) with respect to any
Collateral.

         (e) The Collateral Agent hereby agrees that all liens, pledges and
other security interests of any kind or nature held by it (other than liens,
pledges and security interests arising hereunder) in any of the Collateral
securing any obligation to the


                                       5
<PAGE>   8
Collateral Agent (either in such capacity or in any other capacity)
(collectively, "OTHER LIENS") shall be subordinate and junior to the liens,
pledges and security interests in the Collateral arising hereunder and that the
Collateral Agent will take no action to enforce any Other Liens so long as any
obligation under the Securities Contract or hereunder (whether or not then due)
should remain unsatisfied.

         SECTION 5. Certain Covenants of Pledgor. Pledgor agrees that, so long
as any of the obligations of Parent or Pledgor under the Securities Contract
remain outstanding:

         (a) Pledgor shall ensure at all times that a Collateral Event of
Default shall not occur, and shall pledge additional Collateral in the manner
described in Sections 6(b) and 6(c) as necessary to cause such requirement to be
met.

         (b) Pledgor shall, at the expense of either Parent or Pledgor and in
such manner and form as Secured Party or the Collateral Agent may require, give,
execute, deliver, file and record any financing statement, notice, instrument,
document, agreement or other papers that may be necessary or desirable in order
to create, preserve, perfect, substantiate or validate any security interest
granted pursuant hereto or to enable the Collateral Agent to exercise and
enforce its rights and the rights of Secured Party hereunder with respect to
such security interest. To the extent permitted by applicable law, Pledgor
hereby authorizes the Collateral Agent to execute and file, in the name of
Pledgor or otherwise, UCC financing or continuation statements (which may be
carbon, photographic, photostatic or other reproductions of this Agreement or of
a financing statement relating to this Agreement) that the Collateral Agent in
its sole discretion may deem necessary or appropriate to further perfect, or
maintain the perfection of, the Security Interests.

         (c) Pledgor shall warrant and defend its title to the Collateral,
subject to the rights of the Collateral Agent and Secured Party, against the
claims and demands of all persons. The Collateral Agent and Secured Party (or,
as they may agree, one of them) may elect, but without an obligation to do so,
to discharge any Lien of any third party on any of the Collateral.

         (d) Pledgor agrees that it shall not change (1) its name, identity or
corporate structure in any manner or (2) its Location, unless in either case (A)
it shall have given the Collateral Agent not less than 30 days' prior notice
thereof and (B) such change shall not cause any of the Security Interests to
become unperfected or subject any Collateral to any other Lien.

         (e) Pledgor agrees that it shall not (1) create or permit to exist any
Lien (other than the Security Interests) or any Transfer Restriction (other than
the Existing Transfer Restrictions) upon or with respect to the Collateral, (2)
sell or otherwise dispose of, or grant any option with respect to, any of the
Collateral or (3) enter into or consent to any agreement pursuant to which any
person other than the Pledgor, the Collateral Agent, the Secured Party and any
securities intermediary through whom any of the Collateral is held (but in the
case of any such securities intermediary only in respect of Collateral held


                                       6

through it) has or will have control (within the meaning of Section 8-106 of the
UCC) in respect of any Collateral.

         SECTION 6. Administration of the Collateral and Valuation of the
Securities. (a) The Collateral Agent shall determine on each Business Day
whether a Collateral Event of Default shall have occurred.

         (b) Pledgor may pledge additional Collateral hereunder at any time.
Concurrently with the delivery of any additional Eligible Collateral, Pledgor
shall deliver to the Collateral Agent a certificate of an Authorized Officer
Pledgor substantially in the form of Exhibit A hereto and dated the date of such
delivery, (A) identifying the additional items of Eligible Collateral being
pledged and (B) certifying that with respect to such items of additional
Eligible Collateral the representations and warranties contained in paragraphs
(a), (b), (c), (d) and (e) of Section 3 are true and correct with respect to
such Eligible Collateral on and as of the date thereof. Pledgor hereby covenants
and agrees to take all actions required under Section 6(c) and any other actions
necessary to create for the benefit of the Collateral Agent a valid, first
priority, perfected security interest in, and a first lien upon, such additional
Eligible Collateral.

         (c) Any delivery of Common Stock (or security entitlement in respect
thereof) as Collateral to the Collateral Agent by Pledgor shall be effected (A)
in the case of Collateral consisting of certificated Common Stock registered in
the name of Pledgor, by delivery of certificates representing such Common Stock
to the Collateral Agent, accompanied by any required transfer tax stamps, and in
suitable form for transfer by delivery or accompanied by duly executed
instruments of transfer or assignment in blank, with signatures appropriately
guaranteed, all in form and substance satisfactory to the Collateral Agent, (B)
in the case of Collateral consisting of uncertificated Common Stock registered
in the name of Pledgor, by transmission by Pledgor of an instruction to the
issuer of such Common Stock instructing such issuer to register such Common
Stock in the name of the Collateral Agent or its nominee, accompanied by any
required transfer tax stamps, and the issuer's compliance with such instructions
or (C) in the case of Common Stock in respect of which security entitlements are
held by Pledgor through a securities intermediary, by the crediting of such
Common Stock, accompanied by any required transfer tax stamps, to a securities
account of the Collateral Agent at such securities intermediary or, at the
option of the Collateral Agent, at another securities intermediary satisfactory
to the Collateral Agent. Upon delivery of any such Pledged Item under this
Agreement, the Collateral Agent shall examine such Pledged Item and any
certificates delivered pursuant to Section 6(b) or otherwise pursuant to the
terms hereof in connection therewith to determine that they comply as to form
with the requirements for Eligible Collateral.

         (d) If on any Business Day the Collateral Agent determines that a
Collateral Event of Default shall have occurred, the Collateral Agent shall
promptly notify Parent and Pledgor of such determination by telephone call to
Parent and to an Authorized Officer of Pledgor followed by a written
confirmation of such call.


                                       7
<PAGE>   10
         (e) If on any Business Day the Collateral Agent determines that no
Acceleration Event or failure by Pledgor to meet any of its obligations under
Sections 5 or 6 hereof has occurred and is continuing, Pledgor may obtain the
release from the Security Interests of any Collateral upon delivery to the
Collateral Agent of a written notice from an Authorized Officer of Pledgor
indicating the items of Collateral to be released so long as, after such
release, no Collateral Event of Default shall have occurred.

         (f) On the Maturity Date, unless (i) Parent or Pledgor shall have
otherwise effected the deliveries required by Section 2.03(b) of the Securities
Contract or shall have delivered the Cash Settlement Amount to Secured Party in
lieu of shares of Common Stock (or security entitlements in respect thereof) in
accordance with Section 2.04 of the Securities Contract on the Maturity Date or
(ii) the Common Stock (or security entitlements in respect thereof) then held by
the Collateral Agent hereunder is not Free Stock, the Collateral Agent shall
deliver (and Pledgor hereby irrevocably instructs the Collateral Agent to
deliver, in whole or partial, as the case may be, satisfaction of Pledgor's
obligations to deliver shares of Common Stock (or security entitlements in
respect thereof) to Secured Party on the Maturity Date pursuant to the
Securities Contract) to Secured Party shares of Common Stock (or security
entitlements in respect thereof) then held by it hereunder representing the
number of shares of Common Stock (or security entitlements in respect thereof)
required to be delivered under the Securities Contract on the Maturity Date.
Upon any such delivery, Secured Party shall hold such shares of Common Stock (or
security entitlements in respect thereof) absolutely and free from any claim or
right whatsoever (including, without limitation, any claim or right of Pledgor).

         (g) The Collateral Agent may at any time or from time to time, in its
sole discretion, cause any or all of the Common Stock pledged hereunder (or in
respect of which security entitlements are pledged hereunder) registered in the
name of Pledgor or its nominee to be transferred of record into the name of the
Collateral Agent or its nominee. Pledgor shall promptly give to the Collateral
Agent copies of any notices or other communications received by Pledgor with
respect to Common Stock (or security entitlements in respect thereof) pledged
hereunder registered, or held through a securities intermediary, in the name of
Parent or its nominee, or Pledgor or its nominee and the Collateral Agent shall
promptly give to Pledgor copies of any notices and communications received by
the Collateral Agent with respect to Common Stock (or security entitlements in
respect thereof) pledged hereunder registered, or held through a securities
intermediary, in the name of the Collateral Agent or its nominee.

         (h) Pledgor agrees that either Parent or Pledgor shall forthwith upon
demand pay to the Collateral Agent:

                  (i) the amount of any taxes that the Collateral Agent or
         Secured Party may have been required to pay by reason of the Security
         Interests or to free any of the Collateral from any Lien thereon, and


                                       8
<PAGE>   11
                  (ii) the amount of any and all out-of-pocket expenses,
         including the fees and disbursements of counsel and of any other
         experts, that the Collateral Agent or Secured Party may incur in
         connection with (A) the enforcement of this Agreement, including such
         expenses as are incurred to preserve the value of the Collateral and
         the validity, perfection, rank and value of the Security Interests, (B)
         the collection, sale or other disposition of any of the Collateral, (C)
         the exercise by the Collateral Agent of any of the rights conferred
         upon it hereunder or (D) any Acceleration Event.

Any such amount not paid on demand shall bear interest (computed on the basis of
a year of 360 days and payable for the actual number of days elapsed) at a rate
per annum equal to the lesser of (i) Secured Party's cost of borrowing as
determined by the Calculation Agent or (ii) 5% plus the prime rate as published
from time to time in The Wall Street Journal, Eastern Edition.

         (i) Without limiting the rights and obligations of the parties under
this Agreement, the Collateral Agent shall, notwithstanding Section 9-207 of the
UCC, have the right, upon the consent of Pledgor (which consent need not be in
writing), to sell, lend, pledge, rehypothecate, assign, invest, use, commingle
or otherwise dispose of, or otherwise use in its business (collectively,
"REHYPOTHECATE"), any Collateral it holds, free from any claim or right of any
nature whatsoever of Parent or Pledgor, including any equity or right of
redemption by Parent or Pledgor; provided that the Collateral Agent will not
lend any Collateral except pursuant to arrangements that (i) give the Collateral
Agent the right to take possession of such Collateral (or substitute Collateral)
upon five Business Days' notice, and the Collateral Agent shall exercise such
right upon notice from Parent, Pledgor or Secured Party, and (ii) provide that
the borrower of any Collateral consisting of Common Stock shall pay or deliver
to the Collateral Agent, for the account of Pledgor, the amount of any dividends
or distributions paid on the borrowed Common Stock, and any such delivery or
payment received by the Collateral Agent shall become proceeds of the Collateral
hereunder and (except in the case of extraordinary dividends or distributions)
shall be subject to payment or delivery over to the Pledgor pursuant to Section
7(a).

         (j) Notwithstanding any other provision of this Agreement and Section
9-207 of the UCC, the Collateral Agent shall have the right to pledge the
Collateral to an affiliate of Secured Party in connection with hedging
transactions in respect of the Securities Contract entered into among Secured
Party and its affiliates in the ordinary course of business, which pledge shall
have no effect on the rights and obligations of Pledgor, the Collateral Agent or
Secured Party hereunder.

         SECTION 7. Income and Voting Rights in Collateral. (a) The Collateral
Agent shall have the right to receive and retain as Collateral hereunder (i) all
proceeds (other than interest, or dividends or distributions that are not
extraordinary dividends or distributions) of the Collateral and (ii) upon the
occurrence and during the continuance of an Acceleration Event, all proceeds of
the Collateral, including, without limitation, interest, or dividends or
distributions that are not extraordinary dividends or distributions


                                       9
<PAGE>   12
("DIVIDEND PROCEEDS"), and Pledgor shall take all such action as the Collateral
Agent shall deem necessary or appropriate to give effect to such right. All such
proceeds that are received by Pledgor shall be received in trust for the benefit
of the Collateral Agent and Secured Party and, if the Collateral Agent so
directs (but only, in the case of Dividend Proceeds, upon the occurrence and
during the continuance of an Acceleration Event), shall be segregated from other
funds of Parent or Pledgor and shall, forthwith upon demand by the Collateral
Agent (but only, in the case of Dividend Proceeds, upon the occurrence and
during the continuance of an Acceleration Event), be paid over to the Collateral
Agent as Collateral in the same form as received (with any necessary
endorsement). The Collateral Agent shall pay or deliver over to Pledgor any
proceeds of any Collateral that the Collateral Agent receives but does not have
the right to retain hereunder. After all Acceleration Events have been cured,
the Collateral Agent's right to retain Dividend Proceeds under this Section 7(a)
shall cease and the Collateral Agent shall pay or deliver over to Pledgor any
such Collateral consisting of Dividend Proceeds retained by it during the
continuance of an Acceleration Event.

         (b) Unless an Acceleration Event shall have occurred and be continuing,
Pledgor shall have the right, from time to time, to vote and to give consents,
ratifications and waivers with respect to the Collateral (other than Collateral
that has been rehypothecated by the Collateral Agent pursuant to Section 6(i)),
and the Collateral Agent shall, upon receiving a written request from Parent or
Pledgor accompanied by a certificate of an Authorized Officer of Pledgor stating
that no Acceleration Event has occurred and is continuing, deliver to Pledgor or
as specified in such request such proxies, powers of attorney, consents,
ratifications and waivers in respect of any of the Collateral that is
registered, or held through a securities intermediary, in the name of the
Collateral Agent or its nominee as shall be specified in such request and shall
be in form and substance satisfactory to the Collateral Agent.

         (c) If an Acceleration Event shall have occurred and be continuing, the
Collateral Agent shall have the right, to the extent permitted by law, and
Pledgor shall take all such action as may be necessary or appropriate to give
effect to such right, to vote and to give consents, ratifications and waivers,
and to take any other action with respect to any or all of the Collateral with
the same force and effect as if the Collateral Agent were the absolute and sole
owner thereof.

         SECTION 8. Remedies upon Acceleration Events. (a) If any Acceleration
Event shall have occurred and be continuing, the Collateral Agent may exercise
on behalf of Secured Party all the rights of a secured party under the Uniform
Commercial Code (whether or not in effect in the jurisdiction where such rights
are exercised) and, in addition, without being required to give any notice,
except as herein provided or as may be required by mandatory provisions of law,
shall: (i) deliver all Collateral consisting of shares of Common Stock (or
security entitlements in respect thereof) (but not in excess of the number
thereof deliverable under the Securities Contract at such time) to Secured Party
on the date of the Acceleration Amount Notice relating to such Acceleration
Event (the "DEFAULT SETTLEMENT DATE") in satisfaction of Parent's and Pledgor's
obligations to deliver Common Stock (or security entitlements in respect
thereof) under the Securities


                                       10
<PAGE>   13
Contract, whereupon Secured Party shall hold such shares of Common Stock (or
security entitlements in respect thereof) absolutely free from any claim or
right of whatsoever kind, including any equity or right of redemption of Parent
or Pledgor that may be waived or any other right or claim of Parent or Pledgor,
and Pledgor, to the extent permitted by law, hereby specifically waives all
rights of redemption, stay or appraisal that Pledgor or Parent has or may have
under any law now existing or hereafter adopted; and (ii) if such delivery shall
be insufficient to satisfy in full all of the obligations of Parent and Pledgor
under the Securities Contract or hereunder, sell all of the remaining
Collateral, or such lesser portion thereof as may be necessary to generate
proceeds sufficient to satisfy in full all of the obligations of Parent or
Pledgor under the Securities Contract or hereunder, at public or private sale or
at any broker's board or on any securities exchange, for cash, upon credit or
for future delivery, and at such price or prices as the Collateral Agent may
deem satisfactory. Pledgor covenants and agrees that it will execute and deliver
such documents and take such other action as the Collateral Agent deems
necessary or advisable in order that any such sale may be made in compliance
with law. Upon any such sale the Collateral Agent shall have the right to
deliver, assign and transfer to the buyer thereof the Collateral so sold. Each
buyer at any such sale shall hold the Collateral so sold absolutely and free
from any claim or right of whatsoever kind, including any equity or right of
redemption of Parent or Pledgor that may be waived or any other right or claim
of Parent or Pledgor, and Pledgor, to the extent permitted by law, hereby
specifically waive all rights of redemption, stay or appraisal that Pledgor or
Parent has or may have under any law now existing or hereafter adopted. The
notice (if any) of such sale required by Section 9-504 of the UCC shall (1) in
case of a public sale, state the time and place fixed for such sale, (2) in case
of sale at a broker's board or on a securities exchange, state the board or
exchange at which such sale is to be made and the day on which the Collateral,
or the portion thereof so being sold, will first be offered for sale at such
board or exchange, and (3) in the case of a private sale, state the day after
which such sale may be consummated. Any such public sale shall be held at such
time or times within ordinary business hours and at such place or places as the
Collateral Agent may fix in the notice of such sale. At any such sale the
Collateral may be sold in one lot as an entirety or in separate parcels, as the
Collateral Agent may determine. The Collateral Agent shall not be obligated to
make any such sale pursuant to any such notice. The Collateral Agent may,
without notice or publication, adjourn any public or private sale or cause the
same to be adjourned from time to time by announcement at the time and place
fixed for the sale, and such sale may be made at any time or place to which the
same may be so adjourned. In case of any sale of all or any part of the
Collateral on credit or for future delivery, the Collateral so sold may be
retained by the Collateral Agent until the selling price is paid by the buyer
thereof, but the Collateral Agent shall not incur any liability in case of the
failure of such buyer to take up and pay for the Collateral so sold and, in case
of any such failure, such Collateral may again be sold upon like notice. The
Collateral Agent, instead of exercising the power of sale herein conferred upon
it, may proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

         (b) Pledgor hereby irrevocably appoints the Collateral Agent its true
and lawful attorney, with full power of substitution, in the name of Pledgor,
the Collateral Agent or Secured Party or otherwise, for the sole use and benefit
of the Collateral Agent and Secured Party, but at the expense of either Parent
or Pledgor, to the extent permitted by law, to exercise, at any time and from
time to time while an Acceleration Event has occurred and is continuing, all or
any of the following powers with respect to all or any of the Collateral:

                  (i) to demand, sue for, collect, receive and give acquittance
         for any and all monies due or to become due upon or by virtue thereof,

                  (ii) to settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (iii) to sell, transfer, assign or otherwise deal in or with
         the same or the proceeds or avails thereof, as fully and effectually as
         if the Collateral Agent were the absolute owner thereof (including,
         without limitation, the giving of instructions and entitlement orders
         in respect thereof), and

                  (iv) to extend the time of payment of any or all thereof and
         to make any allowance and other adjustments with reference thereto;

provided that the Collateral Agent shall give Parent and Pledgor not less than
one day's prior written notice of the time and place of any sale or other
intended disposition of any of the Collateral, except any Collateral that
threatens to decline speedily in value, including, without limitation, equity
securities, or is of a type customarily sold on a recognized market. The
Collateral Agent and Pledgor agree that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC.

         (c) Upon any delivery or sale of all or any part of any Collateral made
either under the power of delivery or sale given hereunder or under judgment or
decree in any judicial proceedings for foreclosure or otherwise for the
enforcement of this Agreement, the Collateral Agent is hereby irrevocably
appointed the true and lawful attorney of Pledgor, in the name and stead of
Pledgor, to make all necessary deeds, bills of sale, instruments of assignment,
transfer or conveyance of the property, and all instructions and entitlement
orders in respect of the property thus delivered or sold. For that purpose the
Collateral Agent may execute all such documents, instruments, instructions and
entitlement orders. This power of attorney shall be deemed coupled with an
interest, and Pledgor hereby ratifies and confirms that which its attorney
acting under such power, or such attorney's successors or agents, shall lawfully
do by virtue of this Agreement. If so requested by the Collateral Agent, by
Secured Party or by any buyer of the Collateral or a portion thereof, Parent or
Pledgor shall further ratify and confirm any such delivery or sale by executing
and delivering to the Collateral Agent, to Secured Party or to such buyer or
buyers at the expense of Pledgor all proper deeds, bills of sale, instruments of
assignment, conveyance or transfer, releases, instructions and entitlement
orders as may be designated in any such request.

<PAGE>   15
         (d) In the case of an Acceleration Event, the Collateral Agent may
proceed to realize upon the security interest in the Collateral against any one
or more of the types of Collateral, at any time, as the Collateral Agent shall
determine in its sole discretion subject to the foregoing provisions of this
Section 8. The proceeds of any sale of, or other realization upon, or other
receipt from, any of the Collateral shall be applied by the Collateral Agent in
the following order of priorities:

                  first, to the payment to the Collateral Agent of the expenses
         of such sale or other realization, including reasonable compensation to
         the Collateral Agent and its agents and counsel, and all expenses,
         liabilities and advances incurred or made by the Collateral Agent in
         connection therewith, including brokerage fees in connection with the
         sale by the Collateral Agent of any Collateral;

                  second, to the payment to Secured Party of an amount equal to
         the aggregate Market Value of a number of shares of Common Stock equal
         to (i) the number of shares of Common Stock (or security entitlements
         in respect thereof) that would be required to be delivered under
         Section 7.01 of the Securities Contract on the Default Settlement Date
         without giving effect to the proviso therein minus (ii) the number of
         shares of Common Stock (or security entitlements in respect thereof)
         delivered by the Collateral Agent to Secured Party on the Default
         Settlement Date as described in Section 8(a);

                  finally, if all of the obligations of Parent and Pledgor
         hereunder and under the Securities Contract have been fully discharged
         or sufficient funds have been set aside by the Collateral Agent at the
         request of Parent or Pledgor for the discharge thereof, any remaining
         proceeds shall be released to Pledgor.

         SECTION 9. The Collateral Agent. (a) Secured Party hereby irrevocably
appoints and authorizes the Collateral Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Collateral Agent by the terms hereof, together with all such powers as are
reasonably incidental thereto.

         (b) The obligations of the Collateral Agent hereunder are only those
expressly set forth in this Agreement.

         (c) The Collateral Agent may consult with legal counsel, independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

         (d) Neither the Collateral Agent nor any of its directors, officers,
agents or employees shall be liable for any action taken or not taken by it in
connection with this Agreement (1) with the consent or at the request of Secured
Party or (2) in the absence of its own gross negligence or willful misconduct.
The Collateral Agent shall not incur any liability by acting in reliance upon
any notice, consent, certificate, statement, or other


                                       13
<PAGE>   16
writing (which may be a bank wire, telex or similar writing) believed by it to
be genuine or to be signed by the proper party or parties.

         (e) Pledgor shall indemnify the Collateral Agent against any cost,
expense (including counsel fees and disbursements), claim, demand, action, loss
or liability (except such as result from the Collateral Agent's gross negligence
or willful misconduct) that the Collateral Agent may suffer or incur in
connection with this Agreement or any action taken or omitted by the Collateral
Agent hereunder.

         (f) Beyond the exercise of reasonable care in the custody thereof, the
Collateral Agent shall have no duty as to any Collateral in its possession or
control or in the possession or control of any agent, bailee, clearing
corporation or securities intermediary or any income thereon or as to the
preservation of rights against prior parties or any other rights pertaining
thereto. The Collateral Agent shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any agent, bailee, clearing corporation or securities intermediary
selected by the Collateral Agent in good faith (or selected by an agent, bailee,
clearing corporation or securities intermediary so selected by the Collateral
Agent or by any agent, bailee, clearing corporation or securities intermediary
selected in accordance with this parenthetical phrase).

         (g) Any corporation or association into which the Collateral Agent may
be converted or merged, or with which it may be consolidated, or to which it may
sell or transfer its agency business and assets as a whole or substantially as a
whole, or any corporation or association resulting from any such conversion,
sale, merger, consolidation or transfer to which it is a party, shall, subject
to the prior written consent of Secured Party, be and become a successor
Collateral Agent hereunder and vested with all of the title to the Collateral
and all of the powers, discretions, immunities, privileges and other matters as
was its predecessor without, except as provided above, the execution or filing
of any instrument or any further act, deed or conveyance on the part of any of
the parties hereto, anything herein to the contrary notwithstanding.

         SECTION 10. Miscellaneous. (a) Whenever any of the parties hereto is
referred to, such reference shall be deemed to include the successors and
assigns of such party. All the covenants and agreements herein contained by or
on behalf of Pledgor and the Collateral Agent shall bind, and inure to the
benefit of, their respective successors and assigns whether so expressed or not,
and shall be enforceable by and inure to the benefit of Secured Party and its
successors and assigns.

         (b) Any provision of this Agreement may be amended or waived if, and
only if, such amendment or waiver is in writing and signed, in the case of an
amendment, by Pledgor, the Collateral Agent and Secured Party or, in the case of
a waiver, by the party against whom the waiver is to be effective. No failure or
delay by either party in


                                       14
<PAGE>   17
exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law.

         (c) All notices and other communications hereunder shall be in writing
and shall be deemed to have been duly given if mailed or transmitted by any
standard forms of telecommunication. Notices to Pledgor shall be directed to it
at 800 The Safeguard Building, 435 Devon Park Drive, Wayne, Pennsylvania 19087,
Telecopy No. (610) 293-0601, Attention: Chief Financial Officer; notices to the

to Secured Party shall be directed to it in care of CSFP Capital, Inc., Eleven
Madison Avenue, New York, New York 10010, Telecopy No. (212) 325-8175,
Attention: Ricardo Harewood.

         (d) This Agreement shall in all respects be construed in accordance
with and governed by the laws of the State of New York without reference to
choice of law doctrine (provided that as to Pledged Items located in any
jurisdiction other than the State of New York, the Collateral Agent on behalf of
Secured Party shall, in addition to any rights under the laws of the State of
New York, have all of the rights to which a secured party is entitled under the
laws of such other jurisdiction) and each party hereto submits to the
jurisdiction of the Courts of the State of New York. The parties hereto hereby
agree that the Collateral Agent's jurisdiction, within the meaning of Section
8-110(e) of the UCC, insofar as it acts as a securities intermediary hereunder
or in respect hereof, is the State of New York. To the extent permitted by law,
the unenforceability or invalidity of any provision or provisions of this
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

         (e) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND
ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         (f) This Agreement may be executed, acknowledged and delivered in any
number of counterparts and all such counterparts taken together shall be deemed
to constitute one and the same agreement.

         SECTION 11. Termination of Pledge Agreement. This Agreement and the
rights hereby granted by Pledgor in the Collateral shall cease, terminate and be
void upon fulfillment of all of the obligations of Pledgor under the Securities
Contract and hereunder. Any Collateral remaining at the time of such termination
shall be fully released and discharged from the Security Interests and delivered
to Pledgor by the Collateral Agent, all at the request and expense of Pledgor.

conditions of this Agreement, Sellers jointly and severally agree to sell to
Buyer, and Buyer agrees to purchase and acquire from Sellers, the number of
shares of Common Stock (or security entitlements in respect thereof) equal to

         (a) Upon the terms and subject to the conditions of this Agreement,
Buyer shall deliver to Subsidiary the Purchase Price on August 30, 1999 (the
"PAYMENT DATE") at the offices of Davis Polk & Wardwell, 450 Lexington Avenue,
New York, New York 10017, or at such other place as shall be agreed upon by

to the product of (A) the Base Amount and (B) the Exchange Rate, rounded down to

have not otherwise effected such delivery of Common Stock (or security
entitlements in respect thereof) or delivered cash in lieu thereof pursuant to
Section 2.04 and (y) the Common Stock and security entitlements in respect
thereof then held by the Collateral Agent as collateral under the Pledge
Agreement is Free Stock, then (i) Sellers shall be deemed not to have elected to
deliver cash in lieu of shares of Free Stock pursuant to Section 2.04
(notwithstanding any notice by either Seller to the contrary) and (ii) the
delivery provided by this Section 2.03(b) shall be effected by delivery by the
Collateral Agent to Buyer of a number of shares of Free Stock then held by the

thereof required to be delivered by Sellers to Buyer pursuant to this Section

provided

in Section 2.04, Sellers shall be in breach of this Agreement and shall be
liable to Buyer for any losses incurred by Buyer or its affiliates as a result
of such breach, including without limitation losses incurred in connection with
any decrease in the Closing Price of the Common Stock subsequent to the fifth
Exchange Business Day immediately preceding the Maturity Date.

         (c) The "EXCHANGE RATE" shall be determined by the Calculation Agent in
accordance with the following formula, and is subject to adjustment as a result
of certain events as provided in Article 7 and as provided in Section 6(i) of
the Pledge Agreement: (i) if the Maturity Price is less than the Threshold Price
but greater than $63.0424 (the "ISSUE PRICE"), the Exchange Rate shall be a
ratio (rounded upward or downward to the nearest 1/10,000th or, if there is not
a nearest 1/10,000th, to the next lower 1/10,000th) equal to the Issue Price
divided by the Maturity Price, (ii) if the Maturity Price is equal to or greater
than the Threshold Price, the Exchange Rate shall be a ratio (rounded upward or
downward to the nearest 1/10,000th or, if there is not a nearest 1/10,000th, to
the next lower 1/10,000th) equal to the Issue Price divided by the Threshold
Price and (iii) if the Maturity Price is equal to or less than the Issue Price,
the Exchange Rate shall be one (1). "THRESHOLD PRICE" means $77.5421, provided
that if for any period during the term of this Agreement a Rehypothecation
Unavailability (as defined in the Pledge Agreement) shall not have occurred or
shall not be continuing, then the Threshold Price shall be increased by an
amount equal to the product of $1.2609 and a fraction, the numerator of which
shall equal the number of days during the term of this Agreement on which a
Rehypothecation Unavailability shall not have occurred or shall not be
continuing and the denominator of which shall equal 1,096.

         SECTION .2.04 Cash Settlement Option. Sellers may, upon written notice
delivered to Buyer at least 35 Exchange Business Days prior to the Maturity
Date, elect to deliver the Cash Settlement Amount to Buyer on the Maturity Date
by wire transfer of immediately available funds to an account designated by
Buyer, in lieu of the shares of Common Stock (or security entitlements in
respect thereof) to be delivered on the Maturity Date pursuant to Section
2.03(b).

                             TERMINATION BY SELLERS

         SECTION .3.01 Termination by Seller. Sellers may terminate this
Agreement in whole or in part upon 35 Exchange Business Days' prior written
notice to Buyer (the termination date specified in such notice, the "OPTIONAL
TERMINATION DATE"). If Sellers terminate this Agreement in whole, Sellers shall
make a cash payment, by wire transfer of immediately available funds to an
account designated by Buyer, to Buyer on the Optional Termination Date in an
amount equal to the Replacement Value (calculated in the manner set forth in
Section 8.01 as if the Optional Termination Date were the Acceleration Date). If
Sellers terminate this Agreement in part, Sellers shall specify the number of





                                       9
<PAGE>   10
shares of Common Stock with respect to which this Agreement is to be terminated
and (i) Sellers shall make a cash payment, by wire transfer of immediately
available funds to an account designated by Buyer, to Buyer on the Optional
Termination Date in an amount equal to the Replacement Value (calculated in the
manner set forth in Section 8.01 as if the Optional Termination Date were the
Acceleration Date, provided that for purposes of such calculation, the Base
Amount shall be deemed to be such number of shares of Common Stock with respect
to which this Agreement is to be terminated) and (ii) the Base Amount shall be
reduced by such number of shares of Common Stock with respect to which this
Agreement is to be terminated.

                                   ARTICLE 4.

         SECTION .5.01 Conditions. The obligation of Buyer to deliver the

                                   ARTICLE 6.

                                   COVENANTS

         SECTION .6.01 Taxes. Sellers shall pay any and all documentary, stamp,
transfer or similar taxes and charges that may be payable in respect of the
entry into this Agreement and the transfer and delivery of any Common Stock (or
security entitlements in respect thereof) pursuant hereto. Sellers further agree
to make all payments in respect of this Agreement free and clear of, and without
withholding or deduction for or on account of, any present or future taxes,
duties, fines, penalties, assessments or other governmental charges of
whatsoever nature (or interest on any taxes, duties, fines, penalties,
assessments or other governmental charges of whatsoever nature) imposed, levied,
collected, withheld






                                       12
<PAGE>   13
or assessed by, within or on behalf of () the United States or any political
subdivision or governmental authority thereof or therein having power to tax or
() any jurisdiction from or through which payment on the Agreement is made by
the either Seller, or any political subdivision or governmental authority
thereof or therein having power to tax. In the event such withholding or
deduction is imposed, Sellers jointly and severally agree to indemnify the Buyer
for the full amount of such withholding or deduction, as well as any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.

         SECTION .6.02 Forward Contract. Each Seller hereby agrees that: (i) it
will not treat this Agreement, any portion of this Agreement, or any obligation
hereunder as giving rise to any interest income or other inclusions of ordinary
income; (ii) it will not treat the delivery of any portion of the shares of
Common Stock (or security entitlements in respect thereof) or cash to be
delivered pursuant to this Agreement as the payment of interest or ordinary
income; (iii) it will treat this Agreement in its entirety as a forward contract
for the delivery of such shares of Common Stock (or security entitlements in
respect thereof) or cash; and (iv) it will not take any action (including filing
any tax return or form or taking any position in any tax proceeding) that is
inconsistent with the obligations contained in (i) through (iii).
Notwithstanding the preceding sentence, either Seller may take any action or
position required by law, provided that such Seller deliver to Buyer an
unqualified opinion of counsel, nationally recognized as expert in Federal tax
matters and acceptable to Buyer, to the effect that such action or position is
required by a statutory change or a Treasury regulation or applicable court
decision published after the date of this Agreement.

         SECTION .6.03 Notices. Each Seller will cause to be delivered to Buyer:

         (a) Immediately upon the occurrence of any Acceleration Event
hereunder, notice of such occurrence; and

         (b) In case at any time prior to the Maturity Date such Seller or any
officer of such Seller receives notice that any event requiring that an
adjustment be calculated pursuant to Article 7 hereof shall have occurred or be
pending, then such Seller shall promptly cause to be delivered to Buyer a notice
identifying such event and stating, if known to such Seller, the date on which
such event occurred or is to occur and, if applicable, the record date relating
to such event. Such Seller shall cause further notices to be delivered to Buyer
if such Seller or any officer of such Seller shall subsequently receive notice
of any further or revised information regarding the terms or timing of such
event or any record date relating thereto.

         SECTION .6.04 Further Assurances. From time to time from and after the
date hereof through the Maturity Date, each of the parties hereto shall use its
reasonable best efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper and advisable to consummate and
make effective as promptly as practicable the transactions contemplated by this






                                       13
<PAGE>   14
Agreement in accordance with the terms and conditions hereof, including (i)
using reasonable best efforts to remove any legal impediment to the consummation
of such transactions and (ii) the execution and delivery of all such deeds,
agreements, assignments and further instruments of transfer and conveyance
necessary, proper or advisable to consummate and make effective the transactions
contemplated by this Agreement in accordance with the terms and conditions
hereof.

         SECTION .6.05 Actions That Could Cause Either Seller to Become an
Affiliate. Each Seller shall notify Buyer immediately of its intention to (i)
purchase Common Stock (or security entitlements in respect thereof) or any other
equity security of the Issuer in an amount that would cause such Seller to
become the beneficial owner, directly or indirectly, of more than three percent
of the outstanding shares of any equity security of the Issuer, (ii) accept a
position as an officer or director of the Company, (iii) take any action that
would cause such Seller to possess, directly or indirectly, the power to direct
or cause the direction of the management and policies of the Issuer, whether by
ownership of voting securities, by contract or otherwise, or (iv) take any other
action that could reasonably be expected to result in such Seller becoming an
"affiliate," within the meaning of Rule 144 under the Securities Act, of the
Issuer. Each Seller shall not take any such action unless a period of fifteen
Business Days shall have elapsed after receipt of such notice by Buyer and Buyer
shall not have objected in writing to such action during such period.

         SECTION .6.06 Securities Contract. The parties hereto recognize that
the Collateral Agent is a "financial institution" within the meaning of Section
101(22) of Title 11 of the United States Code (the "BANKRUPTCY CODE") and is
acting as agent and custodian for Buyer in connection with this Agreement and
that Buyer is a "customer" of the Collateral Agent within the meaning of said
Section 101(22). The parties hereto further recognize that this Agreement is a
"securities contract," as such term is defined in Section 741(7) of the
Bankruptcy Code, entitled to the protection of Section 555 of the Bankruptcy
Code.

                                   ARTICLE 7.

                                  ADJUSTMENTS

         SECTION .7.01 Dilution Adjustments.

         (a) Following the declaration by the Issuer of the terms of any
Potential Adjustment Event occurring prior to the Maturity Date, the Calculation
Agent will determine whether such Potential Adjustment Event has a diluting or
concentrative effect on the theoretical value of the Common Stock and, if so,
will (i) make the corresponding adjustment, if any, to any one or more of the
Base Amount, the Exchange Rate, the Threshold Price, the Issue Price, the
Maturity Price, the Cash Settlement Amount, any Closing Price and any other
variable relevant to the exercise, settlement or payment terms hereof or of the
Pledge Agreement as the Calculation Agent determines appropriate to account for
that



                                       14
<PAGE>   15
diluting or concentrative effect and (ii) determine the effective date of the
adjustment. The Calculation Agent may (but need not) determine the appropriate
adjustment by reference to the adjustment in respect of such Potential
Adjustment Event made by an options exchange to options on the Common Stock
traded on that options exchange.

         (b) For these purposes, "POTENTIAL ADJUSTMENT EVENT" means any of the
following:


                  (i) a subdivision, consolidation or reclassification of shares
         of Common Stock (which does not constitute a Reorganization Event), or
         a free distribution or dividend of any shares of Common Stock to
         existing holders of Common Stock by way of bonus, capitalization or
         similar issue;

                  (ii) a distribution or dividend to existing holders of Common
         Stock of (A) shares of Common Stock, or (B) other share capital or
         securities granting the right to payment of dividends and/or the
         proceeds of liquidation of the Issuer equally or proportionately with
         such payments to holders of Common Stock, or (C) other types of
         securities, rights or warrants or other assets, in any case for payment
         (cash or other) at less than the prevailing market price as determined
         by the Calculation Agent;

                  (iii) a cash dividend;

                  (iv) a call by the Issuer in respect of shares of Common Stock
         that are not fully paid;

                  (v) a repurchase by the Issuer of shares of Common Stock,
         whether out of profits or capital and whether the consideration for
         such repurchase is cash, securities or otherwise; or

                  (vi) any other similar event that may have a diluting or
         concentrative effect on the theoretical value of the Common Stock.

         Without limiting the foregoing, the parties acknowledge that the
Calculation Agent will make adjustments to the Base Amount, the Threshold Price,
the Issue Price and any other variable relevant to the exercise, settlement or
payment terms hereof or of the Pledge Agreement as the Calculation Agent
determines appropriate to account for the value of all cash dividends (ordinary
or extraordinary) with respect to the Common Stock.

         (c) Notwithstanding the foregoing, in the event of a distribution of
shares of capital stock of a subsidiary of the Issuer that is a Publicly-Traded
Entity (a "SPIN-OFF") made to holders of shares of Common Stock, the Exchange
Rate in effect immediately prior to such Spin-Off shall be adjusted so that
Buyer shall thereafter be entitled to receive, on the Maturity Date, in addition
to the number of shares of Common Stock required to be delivered on the Maturity
Date, the number of shares of common stock of such Publicly-Traded Entity that
Buyer





                                       15
<PAGE>   16
would have owned or been entitled to receive immediately following such Spin-Off
had the shares of Common Stock required to be delivered to Buyer hereunder on
the Maturity Date been delivered immediately prior to such Spin-Off. Following a
Spin-Off, "Original Common Stock" shall mean the common stock of the Issuer and
"New Common Stock" shall mean the common equity securities of the
Publicly-Traded Entity resulting from such Spin-Off.

         SECTION .7.02 Reorganization Events. In the event of (i) any
consolidation or merger of the Issuer with or into another entity (other than a
merger or consolidation in which the Issuer is the continuing corporation and in
which the Common Stock outstanding immediately prior to the merger or
consolidation is not exchanged for cash, securities or other property of the
Issuer or another corporation), (ii) any sale, transfer, lease or conveyance of
the property of the Issuer as an entirety or substantially as an entirety, (iii)
any statutory exchange of securities of the Issuer with another corporation
(other than in connection with a merger or acquisition) or (iv) any liquidation,
dissolution or winding up of the Issuer (any such event, a "REORGANIZATION
EVENT"), then (A) if the surviving or continuing corporation is a
Publicly-Traded Entity, the Exchange Rate in effect immediately prior to such
Reorganization Event shall be adjusted so that Buyer shall thereafter be
entitled to receive, on the Maturity Date, the number of shares of common stock
of the Publicly-Traded Entity that Buyer would have owned or been entitled to
receive immediately following such Reorganization Event had the shares of Common
Stock required to be delivered to Buyer hereunder on the Maturity Date been
delivered immediately prior to such Reorganization Event or (B) if the surviving
or continuing corporation is not a Publicly-Traded Entity, this Agreement shall
terminate and Sellers shall make a payment or delivery to Buyer as provided in
Section 7.04.

         SECTION .7.03 Provisions Relating to Reorganization Events and
Spin-Offs. If a Reorganization Event occurs and clause (B) of Section 7.02 does
not apply, the surviving or continuing corporation shall be deemed to be the
"Issuer" and the common equity securities of such corporation shall be deemed to
be the "Common Stock". If a Spin-Off occurs, the Issuer and the Publicly-Traded
Entity resulting from the Spin-Off shall each be deemed to be the "Issuer" and
the Original Common Stock and the New Common Stock shall each be deemed to be
the "Common Stock". Following any Spin-Off, the Calculation Agent shall
calculate further adjustments pursuant to this Article 7 by applying the
methodology set forth in this Article 7 to both the Original Common Stock and
the New Common Stock.

         SECTION .7.04 Termination and Payment. Following termination of this
Agreement as a result of any Reorganization Event, the Calculation Agent shall
determine the Replacement Value in the manner provided in Section 8.01
(calculated, for purposes of this Section 7.04, as if the Termination Date were
the Acceleration Date, and representing the fair replacement value (including
both intrinsic and time value) to Buyer of an agreement with terms that would
preserve for Buyer the economic equivalent of the payments and deliveries that
Buyer and its affiliates would, but for the occurrence of the Reorganization
Event, have been






                                       16
<PAGE>   17
entitled to receive after the Termination Date hereunder). As promptly as
reasonably practicable after calculation of the Replacement Value, the
Calculation Agent shall deliver to Buyer and Sellers a notice (the "TERMINATION
AMOUNT NOTICE") specifying the Replacement Value. Not later than three Business
Days following delivery of a Termination Amount Notice, Sellers shall make a
cash payment, by wire transfer of immediately available funds to an account
designated by Buyer, to Buyer in an amount equal to the Replacement Value.
Notwithstanding the foregoing, to the extent that any Marketable Securities are
received by holders of Common Stock in such Reorganization Event, then in lieu
of delivering cash as provided in the immediately preceding sentence, Sellers
may deliver Marketable Securities with an equal value (as determined by the
Calculation Agent in its discretion in a commercially reasonable manner).

                                   Article 8.

                                  ACCELERATION

         SECTION .8.01 Acceleration. If one or more of the following events
(each an "ACCELERATION EVENT") shall occur:

         (a) any legal proceeding shall have been instituted or any other event
shall have occurred or condition shall exist that in Buyer's reasonable judgment
could have a material adverse effect on the financial condition of either Seller
or on either Seller's ability to perform such Seller's obligations hereunder, or
that provides a reasonable basis to call into question the validity or binding
effect of any agreement of such Seller hereunder or under the Pledge Agreement;

         (b) such Seller makes an assignment for the benefit of creditors, files
a petition in bankruptcy, is adjudicated insolvent or bankrupt, petitions or
applies to any tribunal for any receiver of or any trustee for such Seller or
any substantial part of such Seller's property, commences any proceeding
relating to such Seller under any reorganization, arrangement, readjustment of
debt, dissolution or liquidation law or statute of any jurisdiction, whether now
or hereafter in effect, or there is commenced against or with respect to such
Seller or any substantial portion of Seller's property any such proceeding and
an order for relief is issued or such proceeding remains undismissed for a
period of 30 days;

         (c) at any time, any representation made or repeated or deemed to have
been made or repeated by either Seller under this Agreement or the Pledge
Agreement or any certificate delivered pursuant hereto or thereto would be
incorrect or misleading if made or repeated as of such time in any respect that,
in the reasonable judgment of Buyer, would have a material adverse effect on
Buyer in respect of the transactions contemplated hereby;

         (d) Sellers fail to deliver shares of Common Stock (or security
entitlements in respect thereof) or cash on the Maturity Date as required by
this Agreement;




                                       17
<PAGE>   18
         (e) such Seller fails to fulfill or discharge when due any of its other
obligations, covenants or agreements under or relating to this Agreement or the
Pledge Agreement (other than the obligation referred to in Section 8.01(d)), and
such failure remains unremedied for 30 days following notice from Buyer;

         (f) due to the adoption of, or any change in, any applicable law after
the date hereof, or due to the promulgation of, or any change in, the
interpretation by any court, tribunal or regulatory authority with competent
jurisdiction of any applicable law after the date hereof, it becomes unlawful
for either Seller to perform any absolute or contingent obligation to make
payment or delivery hereunder or to comply with any other material provision of
this Agreement or the Pledge Agreement;

         (g) in the reasonable judgement of the Calculation Agent, Buyer is
unable to hedge Buyer's exposure to this Agreement in the ordinary course of
Buyer's business through share borrowing arrangements because of the lack of
sufficient shares of Common Stock being made available by lenders (it being
understood that, at any time at which a Rehypothecation Unavailability (as
defined in the Pledge Agreement) shall not have occurred and be continuing,
there shall be deemed to be sufficient shares of Common Stock being made
available by lenders);

         (h) there occurs a default under any indebtedness for money borrowed by
either Seller or its subsidiaries (except CompuCom Systems, Inc. and Tangram
Enterprise Solutions, Inc.), whether such indebtedness now exists or shall
hereafter be created, which indebtedness, individually or in the aggregate, is
in excess of $10,000,000 principal amount, which default shall constitute a
failure to pay any portion of the principal of such indebtedness when due and
payable after the expiration of any applicable grace or cure period with respect
thereto or shall have resulted in such indebtedness becoming or being declared
due and payable prior to the date on which it would otherwise have become due
and payable;

         (i) a Collateral Event of Default within the meaning of the Pledge
Agreement shall occur;

then, upon notice to Sellers from Buyer at any time following an Acceleration
Event, an "ACCELERATION DATE" shall occur, and Sellers shall become obligated to
deliver to Buyer immediately upon receipt of the Acceleration Amount Notice a
number of shares of Free Stock equal to the Acceleration Amount; provided that
if the Collateral Agent proceeds to realize upon any collateral pledged under
the Pledge Agreement and to apply the proceeds of such realization as provided
in paragraph second of Section 8(d) thereof, then, to the extent of such
application of proceeds, Sellers" obligation to deliver Free Stock pursuant to
this paragraph shall be deemed to be an obligation to deliver an amount of cash
equal to the aggregate Market Value of such Free Stock on the Acceleration Date.
The "ACCELERATION AMOUNT" means the quotient obtained by dividing: (i) the
Replacement Value by (ii) the Market Value per share of the Common Stock on the
Acceleration Date, provided that the Acceleration Amount shall not be greater
than the Base Amount.




                                       18
<PAGE>   19
         The "REPLACEMENT VALUE" means an amount determined by the Calculation
Agent representing the fair replacement value (including both intrinsic and time
value) to Buyer of an agreement with terms that would preserve for Buyer the
economic equivalent of the payments and deliveries that Buyer and its affiliates
would, but for the occurrence of the Acceleration Date, have been entitled to
receive after the Acceleration Date hereunder (taking into account any
adjustments pursuant to Section 7.01 or pursuant to Section 6(i) of the Pledge
Agreement that may have been calculated on or prior to the Acceleration Date),
including any loss of bargain, cost of funding or, without duplication, loss or
cost incurred as a result of Buyer terminating, liquidating, obtaining or
reestablishing any hedge or related trading position.

         As promptly as reasonably practicable after calculation of the
Replacement Value, the Calculation Agent shall deliver to either Seller and
Buyer a notice (the "ACCELERATION AMOUNT NOTICE") specifying the Acceleration
Amount of shares of Common Stock (or security entitlements in respect thereof)

Agent. The Collateral Agent represents and warrants to, and agrees with, Pledgor
and Secured Party that:

         (a) The Collateral Agent is a duly incorporated, validly existing and
in good standing under the laws of the jurisdiction of its incorporation, and
has all powers and all material governmental licenses, authorizations, consents
and approvals required to enter into, and perform its obligations under, this
Agreement.

         (b) The execution, delivery and performance by the Collateral Agent of
this Agreement have been duly authorized by all necessary action on the part of
the Collateral Agent and do not and will not violate, contravene or constitute a
default under any provision of applicable law or regulation or of the
constitutive documents of the Collateral Agent or of any material agreement,
judgment, injunction, order, decree or other instrument binding upon the
Collateral Agent.

         (c) This Agreement constitutes a valid and binding agreement of the
Collateral Agent enforceable against the Collateral Agent in accordance with its
terms.

         (d) Subject to Sections 6(i) and 6(j), the Collateral Agent has not and
will not enter into any agreement pursuant to which any person other than the
Pledgor, the Collateral Agent, the Secured Party or any securities intermediary
through whom any Collateral is held (but in the case of any such securities
intermediary only in respect of Collateral held through it) has or will have
control (within the meaning of Section 8-106 of the UCC) with respect to any
Collateral.

         (e) The Collateral Agent hereby agrees that all liens, pledges and
other security interests of any kind or nature held by it (other than liens,
pledges and security interests arising hereunder) in any of the Collateral
securing any obligation to the Collateral Agent (either in such capacity or in
any other capacity) (collectively, "OTHER LIENS") shall be subordinate and
junior to the liens, pledges and security interests in the Collateral arising
hereunder and that the Collateral Agent will take no action to enforce any Other
Liens so long as any obligation under the Securities Contract or hereunder
(whether or not then due) should remain unsatisfied.

         SECTION 5. Certain Covenants of Pledgor. Pledgor agrees that, so long
as any of the obligations of Parent or Pledgor under the Securities Contract
remain outstanding:

         (a) Pledgor shall ensure at all times that a Collateral Event of
Default shall not occur, and shall pledge additional Collateral in the manner
described in Sections 6(b) and 6(c) as necessary to cause such requirement to be
met.

         (b) Pledgor shall, at the expense of either Parent or Pledgor and in
such manner and form as Secured Party or the Collateral Agent may require, give,
execute, deliver, file

                                       7
<PAGE>   8
and record any financing statement, notice, instrument, document, agreement or
other papers that may be necessary or desirable in order to create, preserve,
perfect, substantiate or validate any security interest granted pursuant hereto
or to enable the Collateral Agent to exercise and enforce its rights and the
rights of Secured Party hereunder with respect to such security interest. To the
extent permitted by applicable law, Pledgor hereby authorizes the Collateral
Agent to execute and file, in the name of Pledgor or otherwise, UCC financing or
continuation statements (which may be carbon, photographic, photostatic or other
reproductions of this Agreement or of a financing statement relating to this
Agreement) that the Collateral Agent in its sole discretion may deem necessary
or appropriate to further perfect, or maintain the perfection of, the Security
Interests.

         (c) Pledgor shall warrant and defend its title to the Collateral,
subject to the rights of the Collateral Agent and Secured Party, against the
claims and demands of all persons. The Collateral Agent and Secured Party (or,
as they may agree, one of them) may elect, but without an obligation to do so,
to discharge any Lien of any third party on any of the Collateral.

         (d) Pledgor agrees that it shall not change (1) its name, identity or
corporate structure in any manner or (2) its Location, unless in either case (A)
it shall have given the Collateral Agent not less than 30 days' prior notice
thereof and (B) such change shall not cause any of the Security Interests to
become unperfected or subject any Collateral to any other Lien.

         (e) Pledgor agrees that it shall not (1) create or permit to exist any
Lien (other than the Security Interests) or any Transfer Restriction (other than
the Existing Transfer Restrictions) upon or with respect to the Collateral, (2)
sell or otherwise dispose of, or grant any option with respect to, any of the
Collateral or (3) enter into or consent to any agreement pursuant to which any
person other than the Pledgor, the Collateral Agent, the Secured Party and any
securities intermediary through whom any of the Collateral is held (but in the
case of any such securities intermediary only in respect of Collateral held
through it) has or will have control (within the meaning of Section 8- 106 of
the UCC) in respect of any Collateral.

         SECTION 6. Administration of the Collateral and Valuation of the
Securities. (a) The Collateral Agent shall determine on each Business Day
whether a Collateral Event of Default shall have occurred.

         (b) Pledgor may pledge additional Collateral hereunder at any time.
Concurrently with the delivery of any additional Eligible Collateral, Pledgor
shall deliver to the Collateral Agent a certificate of an Authorized Officer
Pledgor substantially in the form of Exhibit A hereto and dated the date of such
delivery, (A) identifying the additional items of Eligible Collateral being
pledged and (B) certifying that with respect to such items of additional
Eligible Collateral the representations and warranties contained in paragraphs
(a), (b), (c), (d) and (e) of Section 3 are true and correct with respect to
such Eligible Collateral on and as of the date thereof. Pledgor hereby covenants
and agrees to take all actions required under Section 6(c) and any other actions
necessary to create for

                                       8
<PAGE>   9
the benefit of the Collateral Agent a valid, first priority, perfected security
interest in, and a first lien upon, such additional Eligible Collateral.

         (c) Any delivery of Common Stock (or security entitlement in respect
thereof) as Collateral to the Collateral Agent by Pledgor shall be effected (A)
in the case of Collateral consisting of certificated Common Stock registered in
the name of Pledgor, by delivery of certificates representing such Common Stock
to the Collateral Agent, accompanied by any required transfer tax stamps, and in
suitable form for transfer by delivery or accompanied by duly executed
instruments of transfer or assignment in blank, with signatures appropriately
guaranteed, all in form and substance satisfactory to the Collateral Agent, (B)
in the case of Collateral consisting of uncertificated Common Stock registered
in the name of Pledgor, by transmission by Pledgor of an instruction to the
issuer of such Common Stock instructing such issuer to register such Common
Stock in the name of the Collateral Agent or its nominee, accompanied by any
required transfer tax stamps, and the issuer's compliance with such instructions
or (C) in the case of Common Stock in respect of which security entitlements are
held by Pledgor through a securities intermediary, by the crediting of such
Common Stock, accompanied by any required transfer tax stamps, to a securities
account of the Collateral Agent at such securities intermediary or, at the
option of the Collateral Agent, at another securities intermediary satisfactory
to the Collateral Agent. Upon delivery of any such Pledged Item under this
Agreement, the Collateral Agent shall examine such Pledged Item and any
certificates delivered pursuant to Section 6(b) or otherwise pursuant to the
terms hereof in connection therewith to determine that they comply as to form
with the requirements for Eligible Collateral.

         (d) If on any Business Day the Collateral Agent determines that a
Collateral Event of Default shall have occurred, the Collateral Agent shall
promptly notify Parent and Pledgor of such determination by telephone call to
Parent and to an Authorized Officer of Pledgor followed by a written
confirmation of such call.

         (e) If on any Business Day the Collateral Agent determines that no
Acceleration Event or failure by Pledgor to meet any of its obligations under
Sections 5 or 6 hereof has occurred and is continuing, Pledgor may obtain the
release from the Security Interests of any Collateral upon delivery to the
Collateral Agent of a written notice from an Authorized Officer of Pledgor
indicating the items of Collateral to be released so long as, after such
release, no Collateral Event of Default shall have occurred.

         (f) On the Maturity Date, unless (i) Parent or Pledgor shall have
otherwise effected the deliveries required by Section 2.03(b) of the Securities
Contract or shall have delivered the Cash Settlement Amount to Secured Party in
lieu of shares of Common Stock (or security entitlements in respect thereof) in
accordance with Section 2.04 of the Securities Contract on the Maturity Date or
(ii) the Common Stock (or security entitlements in respect thereof) then held by
the Collateral Agent hereunder is not Free Stock, the Collateral Agent shall
deliver (and Pledgor hereby irrevocably instructs the Collateral Agent to
deliver, in whole or partial, as the case may be, satisfaction of Pledgor's
obligations to deliver shares of Common Stock (or security entitlements in
respect thereof) to Secured Party on the Maturity Date pursuant to the
Securities

                                       9
<PAGE>   10
Contract) to Secured Party shares of Common Stock (or security entitlements in
respect thereof) then held by it hereunder representing the number of shares of
Common Stock (or security entitlements in respect thereof) required to be
delivered under the Securities Contract on the Maturity Date. Upon any such
delivery, Secured Party shall hold such shares of Common Stock (or security
entitlements in respect thereof) absolutely and free from any claim or right
whatsoever (including, without limitation, any claim or right of Pledgor).

         (g) The Collateral Agent may at any time or from time to time, in its
sole discretion, cause any or all of the Common Stock pledged hereunder (or in
respect of which security entitlements are pledged hereunder) registered in the
name of Pledgor or its nominee to be transferred of record into the name of the
Collateral Agent or its nominee. Pledgor shall promptly give to the Collateral
Agent copies of any notices or other communications received by Pledgor with
respect to Common Stock (or security entitlements in respect thereof) pledged
hereunder registered, or held through a securities intermediary, in the name of
Parent or its nominee, or Pledgor or its nominee and the Collateral Agent shall
promptly give to Pledgor copies of any notices and communications received by
the Collateral Agent with respect to Common Stock (or security entitlements in
respect thereof) pledged hereunder registered, or held through a securities
intermediary, in the name of the Collateral Agent or its nominee.

         (h) Pledgor agrees that either Parent or Pledgor shall forthwith upon
demand pay to the Collateral Agent:

                  (i) the amount of any taxes that the Collateral Agent or
         Secured Party may have been required to pay by reason of the Security
         Interests or to free any of the Collateral from any Lien thereon, and

                  (ii) the amount of any and all out-of-pocket expenses,
         including the fees and disbursements of counsel and of any other
         experts, that the Collateral Agent or Secured Party may incur in
         connection with (A) the enforcement of this Agreement, including such
         expenses as are incurred to preserve the value of the Collateral and
         the validity, perfection, rank and value of the Security Interests, (B)
         the collection, sale or other disposition of any of the Collateral, (C)
         the exercise by the Collateral Agent of any of the rights conferred
         upon it hereunder or (D) any Acceleration Event.

Any such amount not paid on demand shall bear interest (computed on the basis of
a year of 360 days and payable for the actual number of days elapsed) at a rate
per annum equal to the lesser of (i) Secured Party's cost of borrowing as
determined by the Calculation Agent or (ii) 5% plus the prime rate as published
from time to time in The Wall Street Journal, Eastern Edition.

         (i) Without limiting the rights and obligations of the parties under
this Agreement, the Collateral Agent shall, notwithstanding Section 9-207 of the
UCC, have the right, upon the consent of Pledgor (which consent need not be in
writing), to sell, lend, pledge, rehypothecate, assign, invest, use, commingle
or otherwise dispose of, or

                                       10
<PAGE>   11
otherwise use in its business (collectively, "REHYPOTHECATE"), any Collateral it
holds, free from any claim or right of any nature whatsoever of Parent or
Pledgor, including any equity or right of redemption by Parent or Pledgor;
provided that the Collateral Agent will not lend any Collateral except pursuant
to arrangements that (i) give the Collateral Agent the right to take possession
of such Collateral (or substitute Collateral) upon five Business Days' notice,
and the Collateral Agent shall exercise such right upon notice from Parent,
Pledgor or Secured Party, and (ii) provide that the borrower of any Collateral
consisting of Common Stock shall pay or deliver to the Collateral Agent, for the
account of Pledgor, the amount of any dividends or distributions paid on the
borrowed Common Stock, and any such delivery or payment received by the
Collateral Agent shall become proceeds of the Collateral hereunder and (except
in the case of extraordinary dividends or distributions) shall be subject to
payment or delivery over to the Pledgor pursuant to Section 7(a).

         (j) Notwithstanding any other provision of this Agreement and Section
9-207 of the UCC, the Collateral Agent shall have the right to pledge the
Collateral to an affiliate of Secured Party in connection with hedging
transactions in respect of the Securities Contract entered into among Secured
Party and its affiliates in the ordinary course of business, which pledge shall
have no effect on the rights and obligations of Pledgor, the Collateral Agent or
Secured Party hereunder.

         SECTION 7. Income and Voting Rights in Collateral. (a) The Collateral
Agent shall have the right to receive and retain as Collateral hereunder (i) all
proceeds (other than interest, or dividends or distributions that are not
extraordinary dividends or distributions) of the Collateral and (ii) upon the
occurrence and during the continuance of an Acceleration Event, all proceeds of
the Collateral, including, without limitation, interest, or dividends or
distributions that are not extraordinary dividends or distributions ("DIVIDEND
PROCEEDS"), and Pledgor shall take all such action as the Collateral Agent shall
deem necessary or appropriate to give effect to such right. All such proceeds
that are received by Pledgor shall be received in trust for the benefit of the
Collateral Agent and Secured Party and, if the Collateral Agent so directs (but
only, in the case of Dividend Proceeds, upon the occurrence and during the
continuance of an Acceleration Event), shall be segregated from other funds of
Parent or Pledgor and shall, forthwith upon demand by the Collateral Agent (but
only, in the case of Dividend Proceeds, upon the occurrence and during the
continuance of an Acceleration Event), be paid over to the Collateral Agent as
Collateral in the same form as received (with any necessary endorsement). The
Collateral Agent shall pay or deliver over to Pledgor any proceeds of any
Collateral that the Collateral Agent receives but does not have the right to
retain hereunder. After all Acceleration Events have been cured, the Collateral
Agent's right to retain Dividend Proceeds under this Section 7(a) shall cease
and the Collateral Agent shall pay or deliver over to Pledgor any such
Collateral consisting of Dividend Proceeds retained by it during the continuance
of an Acceleration Event.

         (b) Unless an Acceleration Event shall have occurred and be continuing,
Pledgor shall have the right, from time to time, to vote and to give consents,
ratifications and waivers with respect to the Collateral (other than Collateral
that has been rehypothecated by the Collateral Agent pursuant to Section 6(i)),
and the Collateral Agent shall, upon

                                       11
<PAGE>   12
receiving a written request from Parent or Pledgor accompanied by a certificate
of an Authorized Officer of Pledgor stating that no Acceleration Event has
occurred and is continuing, deliver to Pledgor or as specified in such request
such proxies, powers of attorney, consents, ratifications and waivers in respect
of any of the Collateral that is registered, or held through a securities
intermediary, in the name of the Collateral Agent or its nominee as shall be
specified in such request and shall be in form and substance satisfactory to the
Collateral Agent.

         (c) If an Acceleration Event shall have occurred and be continuing, the
Collateral Agent shall have the right, to the extent permitted by law, and
Pledgor shall take all such action as may be necessary or appropriate to give
effect to such right, to vote and to give consents, ratifications and waivers,
and to take any other action with respect to any or all of the Collateral with
the same force and effect as if the Collateral Agent were the absolute and sole
owner thereof.

         SECTION 8. Remedies upon Acceleration Events. (a) If any Acceleration
Event shall have occurred and be continuing, the Collateral Agent may exercise
on behalf of Secured Party all the rights of a secured party under the Uniform
Commercial Code (whether or not in effect in the jurisdiction where such rights
are exercised) and, in addition, without being required to give any notice,
except as herein provided or as may be required by mandatory provisions of law,
shall: (i) deliver all Collateral consisting of shares of Common Stock (or
security entitlements in respect thereof) (but not in excess of the number
thereof deliverable under the Securities Contract at such time) to Secured Party
on the date of the Acceleration Amount Notice relating to such Acceleration
Event (the "DEFAULT SETTLEMENT DATE") in satisfaction of Parent's and Pledgor's
obligations to deliver Common Stock (or security entitlements in respect
thereof) under the Securities Contract, whereupon Secured Party shall hold such
shares of Common Stock (or security entitlements in respect thereof) absolutely
free from any claim or right of whatsoever kind, including any equity or right
of redemption of Parent or Pledgor that may be waived or any other right or
claim of Parent or Pledgor, and Pledgor, to the extent permitted by law, hereby
specifically waives all rights of redemption, stay or appraisal that Pledgor or
Parent has or may have under any law now existing or hereafter adopted; and (ii)
if such delivery shall be insufficient to satisfy in full all of the obligations
of Parent and Pledgor under the Securities Contract or hereunder, sell all of
the remaining Collateral, or such lesser portion thereof as may be necessary to
generate proceeds sufficient to satisfy in full all of the obligations of Parent
or Pledgor under the Securities Contract or hereunder, at public or private sale
or at any broker's board or on any securities exchange, for cash, upon credit or
for future delivery, and at such price or prices as the Collateral Agent may
deem satisfactory. Pledgor covenants and agrees that it will execute and deliver
such documents and take such other action as the Collateral Agent deems
necessary or advisable in order that any such sale may be made in compliance
with law. Upon any such sale the Collateral Agent shall have the right to
deliver, assign and transfer to the buyer thereof the Collateral so sold. Each
buyer at any such sale shall hold the Collateral so sold absolutely and free
from any claim or right of whatsoever kind, including any equity or right of
redemption of Parent or Pledgor that may be waived or any other right or claim
of Parent or Pledgor, and Parent and Pledgor, to the extent permitted by law,
hereby specifically waive all rights of redemption, stay or appraisal that
Pledgor or Parent

                                       12
<PAGE>   13
has or may have under any law now existing or hereafter adopted. The notice (if
any) of such sale required by Section 9-504 of the UCC shall (1) in case of a
public sale, state the time and place fixed for such sale, (2) in case of sale
at a broker's board or on a securities exchange, state the board or exchange at
which such sale is to be made and the day on which the Collateral, or the
portion thereof so being sold, will first be offered for sale at such board or
exchange, and (3) in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the
Collateral Agent may fix in the notice of such sale. At any such sale the
Collateral may be sold in one lot as an entirety or in separate parcels, as the
Collateral Agent may determine. The Collateral Agent shall not be obligated to
make any such sale pursuant to any such notice. The Collateral Agent may,
without notice or publication, adjourn any public or private sale or cause the
same to be adjourned from time to time by announcement at the time and place
fixed for the sale, and such sale may be made at any time or place to which the
same may be so adjourned. In case of any sale of all or any part of the
Collateral on credit or for future delivery, the Collateral so sold may be
retained by the Collateral Agent until the selling price is paid by the buyer
thereof, but the Collateral Agent shall not incur any liability in case of the
failure of such buyer to take up and pay for the Collateral so sold and, in case
of any such failure, such Collateral may again be sold upon like notice. The
Collateral Agent, instead of exercising the power of sale herein conferred upon
it, may proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

         (b) Pledgor hereby irrevocably appoints the Collateral Agent its true
and lawful attorney, with full power of substitution, in the name of Pledgor,
the Collateral Agent or Secured Party or otherwise, for the sole use and benefit
of the Collateral Agent and Secured Party, but at the expense of either Parent
or Pledgor, to the extent permitted by law, to exercise, at any time and from
time to time while an Acceleration Event has occurred and is continuing, all or
any of the following powers with respect to all or any of the Collateral:

                  (i) to demand, sue for, collect, receive and give acquittance
         for any and all monies due or to become due upon or by virtue thereof,

                  (ii) to settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (iii) to sell, transfer, assign or otherwise deal in or with
         the same or the proceeds or avails thereof, as fully and effectually as
         if the Collateral Agent were the absolute owner thereof (including,
         without limitation, the giving of instructions and entitlement orders
         in respect thereof), and

                  (iv) to extend the time of payment of any or all thereof and
         to make any allowance and other adjustments with reference thereto;

                                       13
<PAGE>   14
provided that the Collateral Agent shall give Parent and Pledgor not less than
one day's prior written notice of the time and place of any sale or other
intended disposition of any of the Collateral, except any Collateral that
threatens to decline speedily in value, including, without limitation, equity
securities, or is of a type customarily sold on a recognized market. The
Collateral Agent and Pledgor agree that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC.

         (c) Upon any delivery or sale of all or any part of any Collateral made
either under the power of delivery or sale given hereunder or under judgment or
decree in any judicial proceedings for foreclosure or otherwise for the
enforcement of this Agreement, the Collateral Agent is hereby irrevocably
appointed the true and lawful attorney of Pledgor, in the name and stead of
Pledgor, to make all necessary deeds, bills of sale, instruments of assignment,
transfer or conveyance of the property, and all instructions and entitlement
orders in respect of the property thus delivered or sold. For that purpose the
Collateral Agent may execute all such documents, instruments, instructions and
entitlement orders. This power of attorney shall be deemed coupled with an
interest, and Pledgor hereby ratifies and confirms that which its attorney
acting under such power, or such attorney's successors or agents, shall lawfully
do by virtue of this Agreement. If so requested by the Collateral Agent, by
Secured Party or by any buyer of the Collateral or a portion thereof, Parent or
Pledgor shall further ratify and confirm any such delivery or sale by executing
and delivering to the Collateral Agent, to Secured Party or to such buyer or
buyers at the expense of Pledgor all proper deeds, bills of sale, instruments of
assignment, conveyance or transfer, releases, instructions and entitlement
orders as may be designated in any such request.

         (d) In the case of an Acceleration Event, the Collateral Agent may
proceed to realize upon the security interest in the Collateral against any one
or more of the types of Collateral, at any time, as the Collateral Agent shall
determine in its sole discretion subject to the foregoing provisions of this
Section 8. The proceeds of any sale of, or other realization upon, or other
receipt from, any of the Collateral shall be applied by the Collateral Agent in
the following order of priorities:

                  first, to the payment to the Collateral Agent of the expenses
         of such sale or other realization, including reasonable compensation to
         the Collateral Agent and its agents and counsel, and all expenses,
         liabilities and advances incurred or made by the Collateral Agent in
         connection therewith, including brokerage fees in connection with the
         sale by the Collateral Agent of any Collateral;

                  second, to the payment to Secured Party of an amount equal to
         the aggregate Market Value of a number of shares of Common Stock equal
         to (i) the number of shares of Common Stock (or security entitlements
         in respect thereof) that would be required to be delivered under
         Section 7.01 of the Securities Contract on the Default Settlement Date
         without giving effect to the proviso therein minus (ii) the number of
         shares of Common Stock (or security entitlements in respect thereof)
         delivered by the Collateral Agent to Secured Party on the Default
         Settlement Date as described in Section 8(a);

                                       14
<PAGE>   15
                  finally, if all of the obligations of Parent and Pledgor
         hereunder and under the Securities Contract have been fully discharged
         or sufficient funds have been set aside by the Collateral Agent at the
         request of Parent or Pledgor for the discharge thereof, any remaining
         proceeds shall be released to Pledgor.

                                       15
<PAGE>   16
         SECTION 9. The Collateral Agent. (a) Secured Party hereby irrevocably
appoints and authorizes the Collateral Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Collateral Agent by the terms hereof, together with all such powers as are
reasonably incidental thereto.

         (b) The obligations of the Collateral Agent hereunder are only those
expressly set forth in this Agreement.

         (c) The Collateral Agent may consult with legal counsel, independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

         (d) Neither the Collateral Agent nor any of its directors, officers,
agents or employees shall be liable for any action taken or not taken by it in
connection with this Agreement (1) with the consent or at the request of Secured
Party or (2) in the absence of its own gross negligence or willful misconduct.
The Collateral Agent shall not incur any liability by acting in reliance upon
any notice, consent, certificate, statement, or other writing (which may be a
bank wire, telex or similar writing) believed by it to be genuine or to be
signed by the proper party or parties.

         (e) Pledgor shall indemnify the Collateral Agent against any cost,
expense (including counsel fees and disbursements), claim, demand, action, loss
or liability (except such as result from the Collateral Agent's gross negligence
or willful misconduct) that the Collateral Agent may suffer or incur in
connection with this Agreement or any action taken or omitted by the Collateral
Agent hereunder.

         (f) Beyond the exercise of reasonable care in the custody thereof, the
Collateral Agent shall have no duty as to any Collateral in its possession or
control or in the possession or control of any agent, bailee, clearing
corporation or securities intermediary or any income thereon or as to the
preservation of rights against prior parties or any other rights pertaining
thereto. The Collateral Agent shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any agent, bailee, clearing corporation or securities intermediary
selected by the Collateral Agent in good faith (or selected by an agent, bailee,
clearing corporation or securities intermediary so selected by the Collateral
Agent or by any agent, bailee, clearing corporation or securities intermediary
selected in accordance with this parenthetical phrase).

         (g) Any corporation or association into which the Collateral Agent may
be converted or merged, or with which it may be consolidated, or to which it may
sell or transfer its agency business and assets as a whole or substantially as a
whole, or any corporation or association resulting from any such conversion,
sale, merger, consolidation or transfer to which it is a party, shall, subject
to the prior written consent of Secured Party, be and become a successor
Collateral Agent hereunder and vested with

                                       16

all of the title to the Collateral and all of the powers, discretions,
immunities, privileges and other matters as was its predecessor without, except
as provided above, the execution or filing of any instrument or any further act,
deed or conveyance on the part of any of the parties hereto, anything herein to
the contrary notwithstanding.

         SECTION 10. Miscellaneous. (a) Whenever any of the parties hereto is
referred to, such reference shall be deemed to include the successors and
assigns of such party. All the covenants and agreements herein contained by or
on behalf of Pledgor and the Collateral Agent shall bind, and inure to the

only if, such amendment or waiver is in writing and signed, in the case of an
amendment, by Pledgor, the Collateral Agent and Secured Party or, in the case of
a waiver, by the party against whom the waiver is to be effective. No failure or
delay by either party in exercising any right, power or privilege hereunder
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided by law.

         (c) All notices and other communications hereunder shall be in writing

with and governed by the laws of the State of New York without reference to
choice of law doctrine (provided that as to Pledged Items located in any
jurisdiction other than the State of New York, the Collateral Agent on behalf of
Secured Party shall, in addition to any rights under the laws of the State of
New York, have all of the rights to which a secured party is entitled under the
laws of such other jurisdiction) and each party hereto submits to the
jurisdiction of the Courts of the State of New York. The parties hereto hereby
agree that the Collateral Agent's jurisdiction, within the meaning of Section
8-110(e) of the UCC, insofar as it acts as a securities intermediary hereunder
or in respect hereof, is the State of New York. To the extent permitted by law,
the unenforceability or invalidity of any provision or provisions of this
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.
