                                PLEDGE AGREEMENT

      THIS PLEDGE AGREEMENT (this "Agreement"), dated as of June 29, 2004, is
made by VISKASE COMPANIES, INC., a Delaware corporation (the "Company"), and
each of its Domestic Restricted Subsidiaries (such capitalized term and other
capitalized terms used but not defined herein having the meanings respectively
ascribed thereto in the Security Agreement (as defined below)) hereafter party
hereto (such Subsidiaries, together with Company, each, a "Pledgor" and,
collectively, the "Pledgors"), in favor of LASALLE BANK NATIONAL ASSOCIATION
("LaSalle"), as collateral agent (together with its successor(s) thereto in such
capacity, "Pledgee") for the Trustee and Holders, in light of the following:

                                    RECITALS:

      A. The Company and LaSalle, as collateral agent and as trustee, have
entered into an Indenture, dated as of June 29, 2004 (as amended, restated,
supplemented or otherwise modified from time to time, the "Indenture"), pursuant
to which the Company has issued 90,000 Units (and, together with any additional
units that may be issued from time to time thereunder or exchanged therefor or
for such additional units, the "Units"), each of which consists of an 11-1/2%
Senior Secured Note due 2011 in a principal amount of $1,000 (and, together with
any additional notes that may be issued by the Company from time to time
thereunder or exchanged therefor or for such additional notes, the "Notes") and
a warrant to purchase 8.947 shares of common stock of the Company, at an
exercise price of $0.01 per share, subject to adjustment.

      B. Each Domestic Restricted Subsidiary of the Company that is not an
Immaterial Subsidiary is required under the Indenture to (a) become a party to
the Indenture and deliver a Guarantee to guarantee the payment of the Notes and
the other Obligations of the Company thereunder and the other Indenture
Documents to which the Company is a party and (b) become a party hereto as a
Pledgor and secure its Obligations under the Indenture, such Guarantee and the
other Indenture Documents to which it is a party pursuant to the terms hereof.

      C. The Pledgors and the Pledgee have entered into that certain Security
Agreement, dated as of June 29, 2004 (as amended, restated, supplemented or
otherwise modified from time to time, the "Security Agreement"), pursuant to
which the Pledgors have granted security interests in certain of their assets
(including the Collateral) as more fully described therein.

      D. The Company and Wells Fargo Foothill, Inc. ("Foothill") have entered
into that certain Loan and Security Agreement dated as of June 29, 2004 (as
amended, restated, supplemented, replaced or otherwise modified from time to
time, the "Credit Agreement").

      E. The Pledgors and Foothill have entered into one or more pledge
agreements, dated as of June 29, 2004 (such pledge agreement(s), together with
any others entered into after the date hereof, the "Credit Agreement Pledge
Agreement"), pursuant to which the Pledgors have granted a security interest in
the Collateral in favor of the Administrative Agent.

      F. The Pledgee, the Administrative Agent and the Company have entered into
that certain Intercreditor and Lien Subordination Agreement, dated as of June
29, 2004 (as amended,

restated, supplemented, replaced or otherwise modified from time to time, the
"Intercreditor Agreement"), which agreement, among other things, sets forth, as
between the Pledgee and the Administrative Agent, the relative priority of their
respective Liens in the Collateral and their rights with respect thereto.

      G. The Company desires to secure its Obligations under the Notes, the
Indenture and each other Indenture Document to which it becomes a party and each
other Pledgor that becomes a party hereto desires to secure its Guarantee, the
Indenture and each other Indenture Document to which it becomes a party by
granting to the Pledgee, for the benefit of itself and the other Secured
Parties, security interests in the Collateral as set forth herein.

      H. To induce the Initial Purchaser to purchase the Units and the
underlying Notes, each Holder to hold the Units and the underlying Notes to be
held by it and LaSalle to act in its capacities as trustee and collateral agent,
each Pledgor desires to pledge, grant, transfer, and assign to the Pledgee, for
the benefit of itself and the other Secured Parties, a security interest in the
Collateral to secure the Obligations, as provided herein.

      NOW, THEREFORE, in consideration of the premises set forth above, the
terms and conditions contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, and each intending
to be bound hereby, the Pledgee and each Pledgor agree as follows:

      1. SECURITY FOR OBLIGATIONS. This Agreement is for the benefit of the
Pledgee and the other Secured Parties to secure the prompt and complete payment
and performance when due of any and all of the Obligations.

      2. DEFINITION OF ISSUERS; DESIGNATED NUMBER; CAPITAL STOCK; PLEDGED
INTERESTS; PLEDGED COLLATERAL. As used herein, (A) the term "Issuers" shall
mean, with respect to each Pledgor, each of the Persons identified as an Issuer
on Annex A attached hereto of such Pledgor (or any addendum or supplement
thereto), and any successors thereto, whether by merger or otherwise; (B) the
term "Designated Number" shall mean, with respect to any Issuer that is (1) a
Domestic Subsidiary of a Pledgor, all of the Capital Stock of such Issuer held
by such Pledgor and (2) a Foreign Subsidiary of a Pledgor, with respect to its
Capital Stock that is (x) not Voting Stock, all of such Capital Stock of such
Issuer held by such Pledgor and (y) Voting Stock, the largest whole number of
shares or units, as the case may be, of Voting Stock of such Issuer held by such
Pledgor representing not greater than sixty- five percent (65%) of all of the
fully diluted issued and outstanding Voting Stock of such Issuer (whether or not
owned by such Pledgor); (C) the term "Pledged Interest" means, with respect to
each Issuer, the Designated Number of Capital Stock identified as Pledged
Interests of such Issuer on Annex A attached hereto of the Pledgor that is a
holder of the Capital Stock of such Issuer (or any addendum or supplement
thereto); (D) the term "Pledged Collateral" means the "Pledged Interests" and
the "Future Rights" as defined in and acquired pursuant to Section 3.2 below,
collectively, and (E) "Excluded Capital Stock" means, with respect to any Issuer
that is a

                                     - 2 -
<PAGE>

Subsidiary of the Company, that portion of such Issuer's Capital Stock that
would otherwise constitute Collateral to the extent the greater of the par
value, book value as carried by the Pledgor that is the holder thereof or the
market value of any such Capital Stock is equal to or greater than 20% of the
aggregate principal amount of the Notes then outstanding. Notwithstanding
anything to the contrary in the immediately preceding sentence, neither the
Pledged Collateral nor the Future Interests relating to any Issuer shall include
any Excluded Capital Stock. Annex A of any Pledgor may be supplemented from time
to time pursuant to Section 3.2 below. Each Pledgor represents and warrants to
the Pledgee for the benefit of the Pledgee and the other Secured Parties that on
the date hereof (a) Annex A attached hereto of such Pledgor correctly identifies
the Pledged Interests and the Pledged Collateral owned by such Pledgor with
respect to Issuers; and (b) such Pledgor is the holder of record and sole
beneficial and legal owner of such Pledged Interests and Pledged Collateral.

      3. PLEDGE OF PLEDGED COLLATERAL AND OTHER COLLATERAL.

      3.1 Pledge. (i) To secure the Obligations and for the purposes set forth
in Section 1 hereof, each Pledgor hereby pledges and collaterally assigns, and
grants a security interest in and lien on, in favor of Pledgee for the benefit
of the Pledgee and the other Secured Parties, all of such Pledgor's right, title
and interest in, to, and under (A) the Pledged Collateral, (B) any additional
Pledged Collateral acquired pursuant to Section 3.2 below (whether by purchase,
dividend, merger, consolidation, sale of assets, split, spin-off, or any other
dividend or distribution of any kind or otherwise), (C) all distributions,
dividends, cash, certificates, liquidation rights and interests, options,
rights, warrants, instruments or other property from time to time received,
receivable or otherwise distributed in respect of or in exchange or substitution
for any and all of the Pledged Collateral (excluding any of the foregoing items
in the preceding clause with respect to an Issuer to the extent and only to the
extent that their inclusion would cause (i) the number of shares or units, as
the case may be, of Capital Stock pledged under this Agreement to exceed, with
respect to such Issuer, the Designated Number or (ii) such Pledged Collateral to
constitute Excluded Capital Stock, in each case, after giving effect to such
issuances), (D) such Pledgor's right to vote the Pledged Collateral, and (E) all
proceeds, products, replacements and substitutions for any of the foregoing, in
each case whether now owned or hereafter acquired by such Pledgor (collectively,
the "Collateral"). Notwithstanding the foregoing, the term Collateral shall in
no event include the Excluded Capital Stock of any Issuer.

      (ii) If the Pledged Collateral is evidenced by certificates, then such
Pledgor shall concurrently herewith deposit with the Pledgee, for the benefit of
itself, the other Secured Parties and the Administrative Agent, in accordance
with the terms of the Intercreditor Agreement, the Pledged Collateral owned by
such Pledgor on the date hereof and the certificates representing the Pledged
Collateral endorsed in blank by such Pledgor or accompanied by undated stock
powers or instruments of transfer, in each case, duly executed in blank by such
Pledgor. If any Capital Stock does not constitute Pledged Collateral but instead
constitutes Excluded Capital Stock that is evidenced by certificates, then such
Pledgor shall concurrently herewith deposit with the Pledgee, (x) for the
benefit of the Administrative Agent (and not any Secured Party), in accordance
with the terms of the Intercreditor Agreement and (y) on behalf of such Pledgor,
such

                                     - 3 -
<PAGE>

Excluded Capital Stock owned by such Pledgor on the date hereof and the
certificates representing such Excluded Capital Stock endorsed in blank by such
Pledgor or accompanied by undated stock powers or instruments of transfer, in
each case, duly executed in blank by such Pledgor. For the avoidance of doubt,
if any certificate or instrument representing any Pledged Collateral also
represents any Excluded Capital Stock, the Lien created hereunder shall only
attach to the Capital Stock evidenced thereby to the extent such Capital Stock
does not constitute Excluded Capital Stock.

      (iii) Whether or not the Pledged Collateral is evidenced by certificates,
such Pledgor shall, and hereby authorizes the Pledgee to, file a Code Financing
Statement naming such Pledgor as debtor and the Pledgee as secured party with
respect to the Collateral in the applicable filing office and in such form and
containing such substance as may be necessary to perfect the security interest
of the Pledgee in the Pledged Collateral by the filing of a Code Financing
Statement; provided, however, that no such authorization shall obligate the
Pledgee to make any such filing. Notwithstanding anything to the contrary
contained in this Agreement, the Pledgee shall not as a result of this Agreement
be responsible or liable for any obligations or liabilities of such Pledgor in
such Pledgor's capacity as a holder of any Capital Stock of any Issuer, and the
Pledgee shall not be deemed to have assumed any of such obligations or
liabilities.

      3.2 Subsequently Acquired Pledged Collateral. (i) If at any time or from
time to time after the date hereof during the term of this Agreement, any
Pledgor shall acquire any additional Pledged Interests, including any further
stock, or equity in each Issuer (whether by purchase, dividend, merger,
consolidation, sale of assets, split, spin-off, or any other dividend or
distribution of any kind or otherwise) (collectively, the "Future Rights")
(provided, however, that Future Rights under this clause shall exclude any
Future Rights to the extent and only to the extent that (i) their inclusion
would cause the number of shares or units, as the case may be, of Capital Stock
pledged hereunder to exceed the Designated Number or (ii) such Future Rights
would constitute Excluded Capital Stock, in each case, after giving effect to
the issuance of such Future Rights and any related issuances).

      (ii) Such Pledgor will forthwith pledge and, if applicable, deposit such
additional Pledged Collateral with the Pledgee, for the benefit of itself, the
other Secured Parties and the Administrative Agent in accordance with the terms
of the Intercreditor Agreement and deliver to the Pledgee, for the benefit of
itself, the other Secured Parties and the Administrative Agent in accordance
with the terms of the Intercreditor Agreement, certificates or instruments
therefor, endorsed in blank by such Pledgor or accompanied by undated stock
powers or instruments of transfer, in each case, duly executed in blank by such
Pledgor, and will promptly thereafter deliver to the Pledgee, for the benefit of
itself, the other Secured Parties and the Administrative Agent in accordance
with the terms of the Intercreditor Agreement, a certificate (which shall be
deemed to supplement Annex A attached hereto of such Pledgor) executed by such
Pledgor describing such Pledged Collateral and the other Pledged Collateral
pledged to the Pledgee, and certifying that the same have been duly pledged with
the Pledgee hereunder. If any Capital Stock does not constitute any such
additional Pledged Collateral but instead constitutes Excluded Capital Stock
that is evidenced by certificates, then such Pledgor shall concurrently promptly
thereafter deposit with the Pledgee, (x) for the benefit of the Administrative
Agent (and not any

                                     - 4 -
<PAGE>

Secured Party), in accordance with the terms of the Intercreditor Agreement and
(y) on behalf of such Pledgor, such Excluded Capital Stock owned by such Pledgor
on the date hereof and the certificates representing such Excluded Capital Stock
endorsed in blank by such Pledgor or accompanied by undated stock powers or
instruments of transfer, in each case, duly executed in blank by such Pledgor.
For the avoidance of doubt, if any certificate or instrument representing any
such additional Pledged Collateral also represents any Excluded Capital Stock,
the Lien created hereunder shall only attach to the Capital Stock evidenced
thereby to the extent such Capital Stock does not constitute Excluded Capital
Stock.

      (iii) Whether or not such additional Pledged Collateral is evidenced by
certificates, such Pledgor shall, and hereby authorizes the Pledgee to, file a
Code Financing Statement naming such Pledgor as debtor and the Pledgee as
secured party with respect to the additional Collateral in the applicable filing
office and in such form and containing such substance as may be necessary to
perfect the security interest of the Pledgee in the additional Collateral by the
filing of a Code Financing Statement; provided, however, that no such
authorization shall obligate the Pledgee to make any such filing.

      3.3 Uncertificated Pledged Collateral. In addition to anything contained
in Sections 3.1 and 3.2 hereof, if any Pledged Collateral (whether now owned or
hereafter acquired) is not certificated or becomes an uncertificated security,
the applicable Pledgor shall promptly notify the Pledgee thereof and shall
promptly take all actions required to perfect or improve the perfection of the
security interest and pledge in favor of the Pledgee under applicable law
(including, in any event, any action required or appropriate under this
Agreement or the Code). Such Pledgor further agrees to take such actions as may
be necessary to permit the Pledgee to exercise any of its rights and remedies
hereunder.

      4. VOTING, ETC. Until the occurrence and continuance of an Event of
Default, each Pledgor shall be entitled to vote any and all of the Pledged
Collateral and the Excluded Capital Stock; provided, however, that no vote shall
be cast or any action taken by such Pledgor with respect to any Pledged
Collateral or Excluded Capital Stock which would violate or be materially
inconsistent with any of the terms of this Agreement, the Indenture, any other
Indenture Document, or which would have the effect of materially impairing the
position or interests of the Pledgee or which would authorize or effect actions
prohibited under the terms of the Indenture or any Indenture Document. All such
rights of such Pledgor to vote any Pledged Collateral shall cease upon the
occurrence and during the continuance of an Event of Default, if the Pledgee so
directs and provides notice to such Pledgor to do so; provided, however, that
upon the cure or waiver of such Event of Default, all rights of the Pledgee to
vote any and all of the Pledged Collateral shall cease. Upon the giving of any
such notice by the Pledgee, such Pledgor shall retain the right to exercise all
voting and other consensual rights relating to all Excluded Capital Stock
applicable to it so long as it exercises any such voting or other consensual
right in a manner identical to the exercise by the Pledgee of any such voting or
other consensual right of the Capital Stock (of the Issuer of such Excluded
Capital Stock) constituting Pledged Collateral applicable to such Pledgor.

                                     - 5 -
<PAGE>

      5. PAYMENTS AND OTHER DISTRIBUTIONS. Until the occurrence and continuance
of an Event of Default and subject in all cases to the Intercreditor Agreement,
all cash, dividends or distributions payable in respect of the Pledged
Collateral (to the extent such payments shall be permitted pursuant to the terms
and provisions of the Indenture) shall be paid to the applicable Pledgor;
provided, however, upon the occurrence and during the continuance of an Event of
Default, all cash, dividends or distributions payable in respect of the Pledged
Collateral shall be paid to the Pledgee as security for the Obligations if the
Pledgee so directs and provides notice to such Pledgor to that effect (it being
understood and agreed that such Pledgor shall retain the right, whether an Event
of Default is outstanding, to receive all cash, dividends or distributions
payable in respect of the Excluded Capital Stock so long as the cash, dividends
or distributions payable in respect of the Excluded Capital Stock are made on a
pro rata basis with the Capital Stock (of the Issuer of such Excluded Capital
Stock) that constitute Pledged Collateral applicable to such Pledgor); provided
further, that upon the cure or waiver of such Event of Default, all cash
dividends or distributions payable in respect of the Pledged Collateral shall be
paid to such Pledgor. The Pledgee shall be entitled to receive directly, and to
retain as part of the Collateral:

            (a) all other or additional securities or investment property, or
      rights to subscribe for or purchase any of the foregoing, or property
      (other than cash) paid or distributed by way of dividend in respect of the
      Pledged Collateral (excluding any of the foregoing items in the preceding
      clause with respect to an Issuer to the extent and only to the extent that
      their inclusion would cause (i) the number of shares or units, as the case
      may be, of such other or additional securities or investment property
      pledged hereunder to exceed the Designated Number or (ii) such other or
      additional securities or investment property to constitute Excluded
      Capital Stock, in each case, after giving effect to such issuances); and

            (b) all other or additional securities, investment property or
      property (including cash) paid or distributed in respect of the Pledged
      Collateral by way of split, spin-off, split-up, reclassification,
      combination of shares or similar rearrangement (excluding any of the
      foregoing items in the preceding clause with respect to an Issuer to the
      extent and only to the extent that their inclusion would cause (i) the
      number of shares or units, as the case may be, of Capital Stock pledged
      hereunder to exceed the Designated Number or (ii) such other or additional
      securities or investment property to constitute Excluded Capital Stock, in
      each case, after giving effect to such issuances).

      Subject to the Intercreditor Agreement, if at any time any Pledgor shall
obtain or possess any of the foregoing Collateral described in this Section,
such Pledgor shall be deemed to hold such Collateral in trust for the Pledgee
for the benefit of the Pledgee and the other Secured Parties, and such Pledgor
shall promptly surrender and deliver such Collateral to the Pledgee.

      6. REMEDIES IN CASE OF AN EVENT OF DEFAULT. (i) Subject to the
Intercreditor Agreement, upon the occurrence and during the continuance of an
Event of Default, the Pledgee shall be entitled to exercise all of the rights,
powers and remedies (whether vested in it by this Agreement, the Indenture, any
other Indenture Documents, and/or in equity or by law,

                                     - 6 -
<PAGE>

and including, without limitation, all rights and remedies of a secured party of
a debtor in default under the Code) for the protection and enforcement of its
rights in respect of the Pledged Collateral, and to the fullest extent permitted
by applicable law, the Pledgee shall be entitled, without limitation, to
exercise the following rights, which each Pledgor hereby agrees to be
commercially reasonable:

            (a) to receive all amounts payable to such Pledgor in respect of the
      Pledged Collateral in accordance with Section 5 hereof;

            (b) to transfer all or any part of the Pledged Collateral into the
      Pledgee's name or the name of its nominee or nominees for the benefit of
      the Pledgee and the other Secured Parties;

            (c) to vote all or any part of the Pledged Collateral and otherwise
      act with respect thereto as though it were the outright owner thereof in
      accordance with Section 4 hereof;

            (d) at any time or from time to time to sell, assign and deliver, or
      grant options to purchase, all or any part of the Pledged Collateral in
      one or more parcels, or any interest therein, at any public or private
      sale at any exchange, broker's board or at any of the Pledgee's offices or
      elsewhere, without demand of performance, advertisement or notice of
      intention to sell or of time or place of sale or adjournment thereof or to
      redeem (all of which, except as may be required by mandatory provisions of
      applicable law, are hereby expressly and irrevocably waived by such
      Pledgor) for cash, on credit or for other property, for immediate or
      future delivery without any assumption of credit risk, and for such price
      or prices and on such terms as the Pledgee in its commercially reasonable
      judgment may determine. Such Pledgor agrees that to the extent that notice
      of sale shall be required by law that at least ten (10) calendar days'
      notice to such Pledgor of the time (which shall be during normal business
      hours) and place of any public sale or the time after which any private
      sale is to be made shall constitute reasonable notification. The Pledgee
      shall not be obligated to make any sale of Pledged Collateral regardless
      of notice of sale having been given. The Pledgee may adjourn any public or
      private sale from time to time by announcement at the time and place fixed
      therefor, and any such sale may, without further notice, be made at the
      time and place to which it was so adjourned. Such Pledgor hereby waives
      and releases to the fullest extent permitted by law any right or equity of
      redemption with respect to the Pledged Collateral, whether before or after
      sale hereunder, and all rights, if any of marshalling the Pledged
      Collateral and any other security for the Obligations or otherwise. At any
      such sale, unless prohibited by applicable law, the Pledgee may bid for
      and purchase all or any part of the Pledged Collateral so sold free from
      any such right or equity of redemption. Neither the Pledgee nor any of the
      other Secured Parties shall be liable for failure to collect or realize
      upon any or all of the Pledged Collateral or for any delay in so doing nor
      shall the Pledgee nor any of the other Secured Parties be under any
      obligation to take any action whatsoever with regard thereto;

                                     - 7 -
<PAGE>

            (e) to settle, adjust, compromise and arrange all accounts,
      controversies, questions, claims and demands whatsoever in relation to all
      or any part of the Pledged Collateral;

            (f) in respect of the Pledged Collateral, to execute all such
      contracts, agreements, deeds, documents and instruments, to bring, defend
      and abandon all such actions, suits and proceedings, and to take all
      actions in relation to all or any part of the Pledged Collateral as the
      Pledgee in its reasonable discretion may determine;

            (g) to appoint managers, sub-agents, officers and servants for any
      of the purposes mentioned in the foregoing provisions of this Section and
      to dismiss the same, all as the Pledgee in its reasonable discretion may
      determine; and

            (h) generally, to take all such other action as the Pledgee in its
      reasonable discretion may determine as incidental or conducive to any of
      the matters or powers mentioned in the foregoing provisions of this
      Section and which the Pledgee may or can do lawfully and to use the name
      of such Pledgor for the purposes aforesaid and in any proceedings arising
      therefrom.

      (ii) During the continuance of any Event of Default, each Pledgor shall
retain the right to exercise all voting and other consensual rights relating to
all Excluded Capital Stock applicable to it so long as it exercises any such
voting or other consensual right in a manner identical to the exercise by the
Pledgee of any such voting or other consensual right of the Capital Stock (of
the Issuer of such Excluded Capital Stock) constituting Pledged Collateral
applicable to such Pledgor and (ii) receive and retain all cash, dividends and
distributions that it would otherwise be entitled to exercise or receive and
retain in respect of the Excluded Capital Stock applicable to it to the extent,
and solely to the extent, that such cash, dividends and distributions are made
on a pro rata basis with the Capital Stock (of the Issuer of such Excluded
Capital Stock) that constitute Pledged Collateral applicable to such Pledgor.

      7. REMEDIES, ETC., CUMULATIVE. (a) Each right, power and remedy of the
Pledgee (for the benefit of the Pledgee and the other Secured Parties) provided
for in this Agreement, the Indenture, any Indenture Document or any other
security agreement, mortgage, guaranty or now or hereafter existing at law or in
equity or by statute shall be cumulative and concurrent and shall be in addition
to every other such right, power or remedy. The exercise or beginning of the
exercise by the Pledgee (for the benefit of the Pledgee and the other Secured
Parties) of any one or more of the rights, powers or remedies provided for in
this Agreement, the Indenture, or any other Indenture Document or now or
hereafter existing at law or in equity or by statute or otherwise shall not
preclude the simultaneous or later exercise by the Pledgee of all such other
rights, powers or remedies, and no failure or delay on the part of the Pledgee
to exercise any such right, power or remedy shall operate as a waiver thereof.

      (b) Each Pledgor authorizes the Pledgee to sell all or any portion of the
Excluded Capital Stock together with all of the Pledged Interests of the Issuer
of such Excluded Capital Stock to the same extent as it is permitted to
authorize the sale of the Pledged Interests hereunder

                                     - 8 -
<PAGE>

without any liability thereto or any duty owed thereby other than as otherwise
expressly required hereunder with respect to such Pledged Interests in the same
sale and on the same terms and for the same consideration as provided in such
sale of the Pledged Interests and at the same price per share or unit of Pledged
Interest as the Excluded Capital Stock; provided that the Pledgee shall promptly
upon receipt of such consideration turn over to such Pledgor (after deducting a
pro rata portion of the costs and expenses incurred in connection with such
sale) the proceeds of such sale relating to the Excluded Capital Stock so sold,
together with a copy of any instruments or other documentation evidencing such
share and an accounting of the costs and expenses applied thereto. Each Pledgor
agrees that the foregoing provisions of this Section 9 shall apply to such
Excluded Capital Stock as if such Excluded Capital Stock were Pledged Interests,
subject to the immediately preceding sentence, the last sentence of Section 4
and Section 6(ii).

      8. APPLICATION OF PROCEEDS. Subject to any mandatory requirements of
applicable law and the terms of the Indenture and the Intercreditor Agreement,
all moneys collected by the Pledgee (for the benefit of the Pledgee and the
other Secured Parties) upon sale or other disposition of the Collateral,
together with all other moneys received by the Pledgee hereunder, shall be
turned over to the Trustee for distribution in accordance with Section 6.10 of
the Indenture.

      9. INDEMNITY. Without duplication of any amounts payable under any other
similar indemnity provision set forth in the Indenture or any other Indenture
Documents, each Pledgor shall, jointly and severally: (i) pay all out-of-pocket
costs and expenses of the Pledgee incurred in connection with the administration
of and in connection with the preservation of rights under, and enforcement of,

be necessary and wherever required or permitted by law in order to perfect and
preserve the Pledgee's security interest in the Collateral, and hereby
authorizes the Pledgee to file financing statements and amendments thereto
relative to all or any part of the Collateral (provided, however, that no such
authorization shall obligate the Pledgee to make any such filing), and agrees to
do such further acts and things and to promptly execute and deliver to the

Parties and the Administrative Agent hereunder and under the Credit Agreement
Pledge Agreement constitute valid and perfected security interests therein
superior and prior to the rights or claims of any other person or entity
therein.

      13.2 No Liens; Other Financing Statements.

hereafter during the term of this Agreement, freely transferable without
restriction or limitation (except as limited by the terms of this Agreement).

are not dealt in or traded on securities exchanges or in securities markets,
(ii) do not have terms expressly providing that they are securities governed by

not, therefore, "securities" governed by Article 8 of the Code.

      13.6 Litigation. There are no actions, suits or proceedings pending or, to
such Pledgor's best knowledge, threatened against or involving such Pledgor
before any court with respect to any of the transactions contemplated by this

such Pledgor hereunder.

      13.7 State of Organization. Such Pledgor's state of organization is
specified on Annex A of such Pledgor.

      13.8 Continued Existence. Upon any transfer of the Pledged Collateral to

have been paid and performed in full (other than contingent indemnification
obligations) or the Defeasance thereof shall have been consummated and this

      14.1 Collateral. (a) Such Pledgor will use its commercially reasonable
efforts to defend the Pledgee's right, title and security interest in and to the
Collateral against the claims and demands of all Persons whomsoever; (b) such
Pledgor will have good and marketable title to and right to pledge any other
property at any time hereafter constituting Collateral and will likewise use its
commercially reasonable efforts to defend the right thereto and security
interest therein of the Pledgee; and (c) such Pledgor will not, with respect to
any Pledged Collateral, enter into any shareholder type agreements, voting
agreements, voting trusts, trust deeds, irrevocable proxies or any other similar
agreements or instruments, other than any shareholder type agreements, voting
agreements, voting trusts, trust deeds, irrevocable proxies or any other similar
agreements or instruments which would not (x) be inconsistent with the terms of
this Agreement, (y) materially and adversely affect the Pledgee's interest in
any of the Pledged Collateral or (z) have a Material Adverse Effect.

      14.3 Compliance with Laws. Such Pledgor will comply with all requirements
of law applicable to the Pledged Collateral or any part thereof, except where
the failure to comply could not reasonably be expected to have a Material
Adverse Effect.

Pledgor shall use its best efforts to prevent the Issuers from issuing Future

basis between Capital Stock of such Issuers constituting Pledged Interests and
Excluded Capital Stock.

      14.5 No Impairment. Such Pledgor will not take or permit to be taken any
action which could materially impair the Pledgee's rights in the Pledged
Collateral. Such Pledgor will not create, incur or permit to exist, will use its
commercially reasonable efforts to defend the Pledged Collateral against and
will take such other action as is necessary to remove, any lien or claim on or
to the Pledged Collateral, other than the liens created hereby and liens in
favor of the Administrative Agent in accordance with the Intercreditor
Agreement, and will use its commercially reasonable efforts to defend the right,
title and interest of the Pledgee in and to any of the Pledged Collateral
against the claims and demands of all Persons whomsoever.

<PAGE>

      14.6 Performance by Pledgee of Such Pledgor's Obligations. If such Pledgor
fails to perform or comply with any of the agreements contained herein, the
Pledgee may, upon the occurrence and during the continuance of an Event of
Default, without notice to or consent by such Pledgor, perform or comply or
cause performance or compliance therewith; provided, however, the Pledgee shall
not be under any obligation to taken any such action.

      14.7 Further Identification of Pledged Collateral. Such Pledgor will
furnish to the Pledgee from time to time such reports in connection with the
Pledged Collateral as the Pledgee may reasonably request from time to time.

      14.8 Continuous Perfection. No Pledgor will change its name,
organizational identification number, state of organization or organizational
identity unless such Pledgor shall within ten Business Days of any such change
provide written notice to the Pledgee of such change and file any financing
statements or amendments thereto necessary to continue the perfection of the
Liens of the Pledgee on the Collateral.

      14.9 Stay or Extension Laws. Such Pledgor will not at any time claim,
take, insist upon or invoke the benefit or advantage of or from any law now or
hereafter in force providing for the valuation or appraisement of the Pledged
Collateral prior to any sale or sales thereof to be made pursuant to the
provisions hereof or pursuant to the decree, judgment, or order of any court of
competent jurisdiction; nor, after such sale or sales, claim or exercise any
right under any statute now or hereafter made or enacted by any state to redeem
the property so sold or any part thereof, and such Pledgor hereby expressly
waives (to the extent not prohibited by applicable law), on behalf of such
Pledgor and each and every person or entity claiming by, through and under such
Pledgor, all benefit and advantage of any such law or laws, and covenants that
such Pledgor will not invoke or utilize any such law or laws or otherwise
hinder, delay or impede the execution of any power, right or remedy herein or
hereby granted and delegated to the Pledgee, but will authorize, allow and
permit the execution of every such power, right or remedy as though no such law
or laws had been made or enacted.

      14.10 The Issuers' Records. Such Pledgor shall cause each of the Issuers
to make a notation on its respective records indicating the interest granted
hereby in favor of the Pledgee.

      15. EACH PLEDGOR'S OBLIGATIONS ABSOLUTE, ETC. The obligations of each
Pledgor under this Agreement shall be absolute and unconditional in accordance
with its terms and shall remain in full force and effect (except as otherwise
provided herein under Section 19) without regard to, and shall not be released,
suspended, discharged, terminated or otherwise affected by, any circumstance or
occurrence whatsoever, including, without limitation: (a) any change in the
time, place or manner of payment of, or in any other term of, all or any of the
Obligations, any waiver, indulgence, renewal, extension, amendment or
modification of or addition, consent or supplement to or deletion from or any
other action or inaction under or in respect of this Agreement, the Indenture or
any other Indenture Document, or any of the other documents, instruments or
agreements relating to the Obligations or any other instrument or agreement
referred to therein or any assignment or transfer of any thereof; (b) any lack
of validity or enforceability of the Indenture, or any other Indenture Document,
or any other

                                     - 13 -
<PAGE>

documents, instruments or agreement referred to therein or any assignment or
transfer of any thereof; (c) any furnishing of any additional security or
collateral to the Pledgee, for the benefit of the Pledgee and/or the other
Secured Parties; or its assignees or any acceptance thereof or any release of
any security by the Pledgee or its assignees; (d) any limitation on any party's
liability or obligations under any such instrument or agreement or any
invalidity or unenforceability, in whole or in part, of any such instrument or
agreement or any term thereof; (e) any bankruptcy, insolvency, reorganization,
composition, adjustment, dissolution, liquidation or other like proceeding
relating to such Pledgor or any other Person, as applicable, or any action taken
with respect to this Agreement by any trustee or receiver, or by any court, in
any such proceeding, whether or not such Pledgor shall have notice or knowledge
of any of the foregoing; (f) any exchange, release or nonperfection of any other
collateral, or any release, or amendment or waiver of or consent to departure
from any guaranty or security, for all or any of the Obligations; or (g) any
other circumstance which might otherwise constitute a defense available to, or a
discharge of, such Pledgor.

      16. NOTICES, ETC. Except as otherwise expressly provided herein, any
notice required or desired to be served, given or delivered hereunder shall be
in the form and manner, and shall be addressed to the parties set forth in the
Indenture.

      17. POWER OF ATTORNEY. Each Pledgor hereby absolutely and irrevocably
constitutes and appoints the Pledgee for the benefit of the Pledgee and the
other Secured Parties as such Pledgor's true and lawful agent and
attorney-in-fact with full power of substitution, in the name of such Pledgor
upon the occurrence and during the continuance of an Event of Default: (a) to
execute and do all such assurances, acts and things which such Pledgor ought to
do but has failed to do under the covenants and provisions contained in this
Agreement; (b) to take any and all such action as may be necessary for the
purpose of maintaining preserving or protecting the security constituted by this
Agreement or any of the rights, remedies, powers or privileges of the Pledgee
under this Agreement; and (c) generally, in the name of such Pledgor, exercise
all or any of the powers, authorities, and discretions conferred on or reserved
to the Pledgee by or pursuant to this Agreement, and (without prejudice to the
generality of any of the foregoing) to deliver or otherwise perfect any deed,
assurance, agreement, instrument or act as may be proper in or for the purpose
of exercising any of such powers, authorities or discretions. Such Pledgor
hereby ratifies and confirms, and hereby agrees to ratify and confirm, whatever
lawful acts the Pledgee or any of the Pledgee's sub-agents or attorneys shall do
or purport to do in the exercise of the power of attorney granted to the Pledgee
pursuant to this Section, which power of attorney, being coupled with an
interest and given for security, is irrevocable; provided, however, that such
Pledgor neither ratifies nor confirms any acts of the Pledgee or any of the
Pledgee's sub-agents or attorneys do in the exercise of this power of attorney
if such acts constitute the negligence, bad faith or willful misconduct of such
Person.

      18. MISCELLANEOUS. Each Pledgor agrees with the Pledgee that each of the
obligations and liabilities of such Pledgor to the Pledgee under this Agreement
may be enforced against such Pledgor without the necessity of joining any other
Person as a party. This Agreement shall create a continuing security interest in
the Pledged Collateral and shall be binding upon the heirs and legal
beneficiaries, and permitted successors and assigns, of such

                                     - 14 -
<PAGE>

Pledgor, as applicable, and shall inure to the benefit of and be enforceable by
the Pledgee and its successors and assigns; provided, however, that no party may
assign this Agreement or any rights or duties hereunder other than pursuant to
the terms of the Indenture. Unless otherwise defined herein, terms defined in
the Code are used herein as therein defined. The headings and titles in this
Agreement are for convenience of reference only and shall not limit or define
the meaning hereof. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which shall
constitute one instrument. If any provision of this Agreement shall prove to be
invalid or unenforceable, such provision shall be deemed to be severable from
the other provisions of this Agreement which shall remain binding on all parties
hereto. No Pledgor shall have any right of subrogation as to any of the Pledged
Collateral until full and complete performance and payment of the Obligations
(other than contingent indemnification obligations) or the Defeasance thereof. A
signature hereto distributed by facsimile or electronic mail shall be deemed to
be as legally binding as a signed original.

      19. TERMINATION; RECOVERY CLAIM. This Agreement shall terminate after the
Obligations are paid in full (other than contingent indemnification obligations)
or the Defeasance thereof. Upon the termination of this Agreement, or as
otherwise provided in the Indenture, the Pledgee, at the request of any
applicable Pledgor and at the cost and expense of such Pledgor, will promptly
execute and deliver to such Pledgor the proper instruments acknowledging the
termination of this Agreement and the security interest and lien on the Pledged
Collateral created hereby and will duly assign, transfer and deliver to such
Pledgor or to whomsoever shall be lawfully entitled to receive the same (without
recourse and without any representation or warranty of any kind) such of the
Pledged Collateral and Excluded Capital Stock as may be in the possession of the
Pledgee and has not theretofore been sold or otherwise applied or released
pursuant to this Agreement. Should a claim ("Recovery Claim") be made upon the
Pledgee or any or all of the other Secured Parties at any time for recovery of
any amount received by the Pledgee or any or all of the other Secured Parties in
payment of the Obligations (whether received such Pledgor or otherwise) and
should the Pledgee or any or all of the other Secured Parties repay all or part
of said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Pledgee or any or all of the
other Secured Parties or any of their respective property; or (b) any settlement
or compromise of any such Recovery Claim effected by the Pledgee or any or all
of the other Secured Parties with the claimant (including, without limitation,
such Pledgor), this Agreement and the security interests granted to the Pledgee
for the benefit of the Pledgee and the other Secured Parties hereunder shall
continue in effect with respect to the amount so repaid to the same extent as if
such amount had never originally been received by the Pledgee or any or all of
the other Secured Parties, notwithstanding any prior termination of this
Agreement, the return of this Agreement to such Pledgor, or the cancellation of
any note or other instrument evidencing the Obligations.

      20. AMENDMENTS; MARSHALLING, ETC. (a) None of the terms or provisions of
this Agreement may be waived, amended, supplemented or otherwise modified except
by a written instrument executed by such Pledgor and the Pledgee.
Notwithstanding the foregoing, the parties hereto agree that in the event that
Rule 3-16 of Regulation S-X under the Securities Act is amended, modified or
interpreted by the SEC to require (or is replaced with another rule or
regulation, or any other law, rule or regulation is adopted, which would
require)

                                     - 15 -
<PAGE>

the filing with the SEC of separate financial statements of any Issuer whose
Capital Stock constitute Pledged Collateral, the term "Excluded Capital Stock"
shall be deemed amended (without further action or consent by any Pledgor, the
Pledgee, the Trustee or any Noteholder) to the extent, and only to the extent,
necessary to avoid the requirement of filing with the SEC of such separate
audited financial statements of such Issuer, and for the avoidance of doubt,
Pledged Interests shall not include any Excluded Capital Stock as amended.

      (b) The Pledgee shall be under no obligation to marshal any assets or
collateral in favor of such Pledgor or any other person or entity or against or
in payment of any or all of the Obligations. All indemnities set forth herein
shall survive the execution and delivery of this Agreement and the making and
repayment of the Obligations or the Defeasance thereof. The Secured Parties
(other than the Pledgee) are the intended third party beneficiaries of this
Agreement.

      21. REVIEW OF AGREEMENT BY EACH PLEDGOR. Each Pledgor acknowledges that
such Pledgor has thoroughly read and reviewed the terms and provisions of this
Agreement, and that such terms and provisions are clearly understood by such
Pledgor, and has been fully and unconditionally consented to by such Pledgor
with the full benefit and advice of counsel chosen by such Pledgor, and that
such Pledgor has freely and voluntarily signed this Agreement without duress.

      22. WAIVER OF CLAIMS. Except as otherwise provided in this Agreement or
prohibited by law, EACH PLEDGOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE PLEDGEE'S
TAKING POSSESSION OR SALE OR THE PLEDGEE'S DISPOSITION OF ANY OF THE COLLATERAL,
INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY
PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH SUCH PLEDGOR WOULD
OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF
ANY STATE, and each Pledgor hereby further waives (and releases any cause of
action and claim against the Pledgee as a result of), to the fullest extent
permitted by law: (a) all damages occasioned by such taking of possession,
collection or sale except any damages which are the direct result of the
Pledgee's gross negligence or willful misconduct; (b) all other requirements as
to the time, place and terms of sale or other requirements with respect to the
enforcement of the Pledgee's rights hereunder; (c) demand of performance or
other demand, notice of intent to demand or accelerate, notice of acceleration,
presentment, protest, advertisement or notice of any kind to or upon such
Pledgor or any other person or entity; and (d) all rights of redemption,
appraisement, valuation, diligence, stay, extension or moratorium now or
hereafter in force under any applicable law in order to delay the enforcement of
this Agreement.

      23. REVIVAL AND REINSTATEMENT OF OBLIGATIONS. If the incurrence or payment
of the Obligations by any Pledgor or the transfer by any Pledgor to the Pledgee
of any property of such Pledgor should for any reason subsequently be declared
to be void or voidable under any state or federal law relating to creditors'
rights, including provisions of the Bankruptcy Code relating to

                                     - 16 -
<PAGE>

fraudulent conveyances, preferences, or other voidable or recoverable payments
of money or transfers of property (collectively, a "Voidable Transfer"), and if
the Pledgee is required to repay or restore, in whole or in part, any such
Voidable Transfer, or elects to do so upon the reasonable advice of its counsel,
then, as to any such Voidable Transfer, or the amount thereof that the Pledgee
is required or elects to repay or restore, and as to all reasonable costs,
expenses, and attorneys fees of the Pledgee related thereto, the liability of
such Pledgor automatically shall be revived, reinstated, and restored and shall
exist as though such Voidable Transfer had never been made.

      24. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICT OF LAWS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT.

      25. WAIVER OF TRIAL BY JURY. EACH PLEDGOR HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

      26. INTEGRATION. This Agreement, together with the other Indenture
Documents, reflects the entire understanding of the parties with respect to the
transactions contemplated hereby and shall not be contradicted or qualified by
any other agreement, oral or written, before the date hereof.

      27. Intercreditor Agreement.

itself and the other Secured Parties in respect of the Collateral and the
exercise of any right related thereto thereby shall be subject, in each case, to

      (b) In the event of any direct conflict between the express terms and
provisions of this Agreement and of the Intercreditor Agreement, the terms and
provisions of the Intercreditor Agreement shall control.

Director.

                                       3
<PAGE>
      2.2. Participation and Deferrals. A Director shall become a Participant by
electing, on a Participation Agreement, to defer the receipt of all or any
portion of the Fees he would otherwise receive with respect to a Plan Year,
consistent with Section 2.3.

      2.3. Participation Agreement. As a condition to the Company's and the
Committee's obligation to withhold and credit deferred Fees for a Participant
under the Plan, the Participant must execute a Participation Agreement on such
forms as shall be prescribed by the Committee.

      (a)   Timing of Execution and Delivery of Participation Agreement. Except
            as provided below, a Participation Agreement must be executed by the
            Participant and the Committee prior to the first day of the Plan
            Year in which the Fees specified in the Participation Agreement will
            be paid. For example, to defer Fees payable in the 2006 Plan Year, a
            Participation Agreement must be executed on or prior to December 31,
            2005. The Participation Agreement may not be amended or revoked
            during the Plan Year.

      (b)   Directors Elected Mid-Year. Notwithstanding subsection (a), a
            non-employee who is elected or appointed to fill a vacancy on the
            Board and who was not a Director on the preceding December 31st may,
            by completing a Participation Agreement, elect to defer Fees for the
            balance of the Plan Year and succeeding Plan Years. In order to
            defer Fees under this subsection (b), the newly elected or appointed
            Director must, within thirty (30) days after such election or
            appointment, execute and deliver a Participation Agreement to the
            Committee, which will be effective for Fees payable on or after the
            date the executed Participation Agreement is delivered to the
            Committee.

      (c)   Modification of Participant Deferral Election. During each December,
            a Participant and the Committee may execute and deliver an amended
            Participation Agreement which increases, decreases, commences or
            terminates the deferral of the Participant's Fees payable after the
            31st day of that December.

                                  ARTICLE III

                            DEFERRALS AND ALLOCATIONS

      3.1. Establishment of Individual Accounts. The Committee shall establish
and maintain an Individual Account for each Participant, to which the Committee
shall credit the Fees deferred by the Participant pursuant to Article II and
from which the Committee shall debit all amounts paid to the Participant or his
or her designated beneficiary pursuant to Article V.

      3.2. Accounting. As of each Accounting Date, each Participant's Individual
Account will be adjusted as follows:

      (a)   First, by charging the Individual Account with any distributions
            pursuant to Article V made to or on behalf of the Participant or his
            or her designated beneficiary since the last Accounting Date.

                                       4
<PAGE>
      (b)   Second, by allocating any Company Stock Dividends which are
            allocable to the Participant's Company Stock Account in accordance
            with Section 3.4.

      (c)   Third, by allocating any interest which is allocable to the
            Participant's Interest Bearing Account in accordance with Section
            3.6.

      (d)   Finally, by crediting the Individual Account with any deferred Fees
            that are to be allocated in accordance with Section 3.7.

      3.3. Conversion of Deferrals. For deferred Fees that are to be invested in
Company Stock and allocated to the Participant's Company Stock Account on any
Allocation Date, such Account shall be credited with a number of shares of
Company Stock, including fractions thereof, determined by dividing the Fair
Market Value of the Company's common stock on that Accounting Date into the
applicable amount of such deferred Fees to be invested in shares of Company
Stock since the last Accounting Date.

      3.4. Allocation of Company Stock Dividends to Company Stock Accounts. As
of each Accounting Date, the number of shares of Company Stock, including
fractions thereof, allocated to a Participant's Company Stock Account shall be
credited with any Company Stock Dividends which were paid with respect to such
shares of Company Stock since the preceding Accounting Date. The aggregate
amount of such Company Stock Dividends shall be divided by the Fair Market Value
of the Company Stock as of the Accounting Date specified in the first sentence
of this Section to determine the number of shares of Company Stock, including
fractions thereof, to be credited to the Participant's Company Stock Account.

      3.5. Changes in Stock. In the event of any change in Company Stock through
stock dividends, split-ups, recapitalizations, reclassifications, conversions or
otherwise, or in the event that other stock shall be converted into or
substituted for the present Company Stock as the result of any merger,
consolidation, reorganization or similar transaction, then the Committee shall
make appropriate adjustment in the aggregate number, price and kind of shares of
Company Stock held in each Individual Account.

      3.6. Allocation of Interest to Interest Bearing Accounts. The interest
rate to be credited to a Participant's Interest Bearing Account as of each
Accounting Date shall be equal to Forty-Five Percent (45%) of the prime rate as
reported in the Wall Street Journal on the applicable Accounting Date. Interest
shall be compounded on each Accounting Date, based on the amount of the
Participant's Individual Account allocated to the Interest Bearing Account as of
the prior Accounting Date.

      3.7. Crediting of Deferrals. All amounts deferred by a Participant
pursuant to Article II shall be credited to the Participant's Individual Account
effective as of the Accounting Date immediately following the period in which
the Fees would otherwise have been paid to the Participant had they not been
deferred.

                                   ARTICLE IV

                             INVESTMENT OF DEFERRALS

      4.1. Trust and Investments. Each Participant's deferrals under the Plan
shall be credited to the Participant's Individual Account as provided in Section
3.2 and may be invested by the Trustee in accordance with the terms and
conditions of the Trust. The Participant may, upon (i) initial enrollment in the
Plan, and (ii) making any subsequent deferral election, direct that his or her
Individual Account be invested in shares of Company Stock in the Trust, credited
to the Interest Bearing Account, or in a combination of these investments. The
Participant may change his or her investment direction at any time after the
initial election; provided, however, any such change shall relate only to Fees
being deferred in the the Plan Year to which the deferral election which
includes the investment direction relates. Thus, once given, an investment
direction applicable to Fees deferred in a particular Plan Year cannot later be
changed insofar as it relates to such Fees.

      4.2. Unsecured Contractual Rights. The Plan at all times shall be unfunded
and shall constitute a mere promise by the Company to make benefit payments in
the future. No provision of the Plan shall impose or be deemed to impose any
obligation upon the Company, other than an unsecured contractual obligation to
make a cash payment to Participants and their beneficiaries in accordance with
the terms of the Plan. Benefits payable under the Plan shall be paid directly by
the Trustee from the Trust or by the Company from its general assets.
Notwithstanding any other provision of this Plan, neither a Participant nor his
designated beneficiary shall have any preferred claim on, or any beneficial
ownership interest in, any assets of the Company or any Affiliate prior to the
time benefits are distributed as provided in Article V.

                                   ARTICLE V

                                  DISTRIBUTIONS

      5.1. Time of Payment of Benefits. All amounts credited to a Participant's
Individual Account shall be distributed for the benefit of a Participant (or his
designated beneficiary) as soon as administratively practicable following the
earlier of (i) the Participant's death, (ii) the date the Participant ceases to
be a Director or (iii) the date elected by the Director.

      5.2. Method of Payment of Benefits. The balance of a Participant's
Individual Account shall be distributed in a single sum payment unless the
Participant has made an election, at the time of his or her initial deferral
election, to receive the distribution in annual installments over a period of
five (5) years. All shares of Company Stock held in the Company Stock Account at
the time of distribution will be distributed in kind, and all amounts invested
in the Interest Bearing Account at the time of distribution will be distributed
in cash.

      5.3. Benefit Payment Elections. In order to be effective, a Participant's
election to receive installment payments or to select an earlier distribution
date must be made by delivering a Participation Agreement to the Committee that
includes such elections at the same time as the

                                       6
<PAGE>
Participant's initial deferral election. If the Participant does not elect to
receive installment payments or if such election is not timely or properly made
under this Section 5.3, the Company shall pay the entire benefit in the form of
a single sum within nine (9) months after the date the Participant first becomes
eligible for the distribution under Section 5.1. If the Participant does not
elect an additional distribution date, or if such election is not timely or
properly made under this Section 5.3, the Company shall pay the benefit at the
time provided in Section 5.1.

      5.4. Death of a Participant and Beneficiary Designation.

      (a)   Time of Payment. In the event of a Participant's death prior to the
            time his benefits under the Plan are distributed, the balance in his
            Individual Account shall be paid, or begin to be paid, to his
            designated beneficiary within nine (9) months of the date of the
            Participant's death.

      (b)   Designation of Beneficiaries. The Participant may designate a
            primary and contingent beneficiary or beneficiaries on forms
            provided by the Committee, which for this purpose may include the
            Participation Agreement. Such designation may be changed at any time
            for any reason by the Participant. If the Participant fails to
            designate a beneficiary, or if such designation shall for any reason
            be illegal or ineffective, or if the designated beneficiary(ies)
            shall not survive the Participant, his benefits under the Plan shall
            be paid to his estate.

      5.5. Participant Ceases to be a Director. In the event a Participant
ceases to be a Director prior to the time his benefits under the Plan are
distributed, the balance in his Individual Account shall be paid, or begin to be
paid, within nine (9) months of the Participant's cessation as a Director.

                                   ARTICLE VI

                               PLAN ADMINISTRATION

      6.1. Administration by the Committee. The Committee shall be responsible
for administering the Plan. Except as the Company shall otherwise expressly
determine, the Committee shall be charged with the full power and the
responsibility for administering the Plan in all its details. No Participant who
is also a member of the Committee shall vote on any matter concerning that
Participant's individual benefit hereunder.

      6.2. Powers and Responsibilities of the Committee.

      (a)   The Committee shall have all powers necessary to administer the
            Plan, including the power to construe and interpret the Plan
            documents; to decide all questions relating to an individual's
            eligibility to participate in the Plan; to determine the amount,
            manner and timing of any distribution of benefits under the Plan; to
            resolve any claim for benefits in accordance with Section 6.4, and
            to appoint or employ advisors, including legal counsel, to render
            advice with respect to any of the Committee's responsibilities under
            the Plan. Any construction, interpretation,

                                       7
<PAGE>
            or application of the Plan by the Committee shall be final,
            conclusive and binding on all persons. All actions by the Committee
            shall be taken pursuant to uniform standards applied to all
            similarly situated persons.

      (b)   Records and Reports. The Committee shall be responsible for
            maintaining sufficient records to determine each Participant's
            eligibility to participate in the Plan, and the Fees of each
            Participant for purposes of determining the amount of contributions
            that may be made by or on behalf of the Participant under the Plan.

      (c)   Rules and Decisions. The Committee may adopt such rules as it deems
            necessary, desirable or appropriate in the administration of the
            Plan. All rules and decisions of the Committee shall be applied
            uniformly and consistently to all Participants in similar
            circumstances. When making a determination or calculation, the
            Committee shall be entitled to rely upon information furnished by a
            Participant or beneficiary, the Company or the Company's legal
            counsel.

      (d)   Application and Forms for Benefits. The Committee may require a
            Participant or beneficiary to complete and file with it an
            application for a benefit, and to furnish all pertinent information
            requested by it. The Committee may rely upon all such information so
            furnished to it, including the Participant's or beneficiary's
            current mailing address.

      6.3. Liabilities. The Committee members shall be indemnified and held
harmless by the Company with respect to any actual or alleged breach of
responsibilities performed or to be performed hereunder in their official
capacities in the administration of the Plan.

      6.4. Claims Procedure.

      (a)   Filing a Claim. Any Participant or beneficiary under the Plan may
            file a written claim for a Plan benefit with the Committee or with a
            person named by the Committee to receive claims under the Plan.

      (b)   Notice of Denial of Claim. In the event of a denial or limitation of
            any benefit or payment due to or requested by any Participant or
            beneficiary under the Plan ("Claimant"), the Claimant shall be given
            a written notification containing specific reasons for the denial or
            limitation of his benefit. The written notification shall contain
            specific reference to the pertinent Plan provisions on which the
            denial or limitation of his benefit is based.

      (c)   Court Action. No Participant or beneficiary shall have the right to
            seek judicial review of a denial of benefits, or to bring any action
            in any court to enforce a claim for benefits prior to filing a claim
            for benefits or exhausting his rights to review under this Section
            6.4.

institution to act as Trustee under the Trust Agreement. The Trustee shall serve
at the pleasure of the Company and

its powers and responsibilities shall be set forth in a written Trust Agreement
between the Company and the Trustee. An amount equal to the amount of
contributions made pursuant to the Plan may be contributed to the Trust and held
by the Trustee in accordance with the terms of the Trust Agreement.

                                  ARTICLE VII

                            AMENDMENT AND TERMINATION

      The Company may amend, suspend or terminate the Plan, in whole or in part,
without the consent of the Committee, Participants, beneficiaries or any other
person, except that no amendment, suspension or termination shall retroactively
impair or otherwise adversely affect (without written consent) the rights of a
Participant or beneficiary which have accrued prior to the date of such action,
as determined by the Committee in its sole discretion. It is noted, however,
that the Participant's benefits under the Plan constitute mere unsecured claims
on the general assets of the Company.

                                  ARTICLE VIII

                               GENERAL PROVISIONS

      8.1. Governing Law. The Plan shall be construed, regulated and
administered according to the laws of the State of Indiana, without regard to
the choice of law principles thereof, except in those areas preempted by the
laws of the United States of America in which case such laws will control.

      8.2. Headings and Gender. The headings and subheadings in the Plan have
been inserted for convenience of reference only and shall not affect the
construction of the provisions hereof. In any necessary construction the
masculine shall include the feminine and the singular the plural, and vice
versa.

      8.3. Participant's Rights; Acquittance. No Participant shall acquire any
right to be retained as a Director by virtue of the Plan, nor, upon his
dismissal, or upon his voluntary termination as a Director shall he have any
right or interest in or to any Plan assets other than as specifically provided
herein.

      8.4. Spendthrift Clause. No benefit or interest available hereunder will
be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, attachment or garnishment by creditors of the
Participant or the Participant's designated beneficiary, either voluntarily or
involuntarily.

      8.5. Counterparts. This Plan may be executed in any number of
counterparts, each of which shall constitute but one and the same instrument and
may be sufficiently evidenced by any one counterpart.

                                       9

      8.6. No Enlargement of Rights. Nothing contained in the Plan shall be
construed as a contract of employment between the Company or any Affiliate and
any person, nor shall the Plan be deemed to give any person the right to be
retained in the employ or as a Director or limit the right of the Company to
employ or discharge any person with or without cause.

      8.7. Limitations on Liability. Notwithstanding any of the preceding
provisions of the Plan, neither the Company, the Committee nor any individual
acting as an employee or agent of the Company shall be liable to any
Participant, Director or beneficiary for any claim, loss, liability or expense
incurred in connection with the Plan, except when the same shall have been
judicially determined to be due to the gross negligence or willful misconduct of
such person.

      8.8. Incapacity of Participant or Beneficiary. If any person entitled to
receive a distribution under the Plan is physically or mentally incapable of
personally receiving and giving a valid receipt for any payment due (unless
prior claim therefor shall have been made by a duly qualified guardian or other
legal representative), then, unless and until claim therefor shall have been
made by a duly appointed guardian or other legal representative of such person,
the Committee may provide for such payment or any part thereof to be made to any
other person or institution then contributing toward or providing for the care
and maintenance of such person. Any such payment shall be a payment for the
account of such person and a complete discharge of any liability of the Company
and the Plan.

      8.9. Corporate Successors. The Plan shall not be automatically terminated
by a transfer or sale of assets of the Company or by the merger or consolidation
of the Company into or with any other corporation or other entity
("Transaction"), but the Plan shall be continued after the Transaction only if
and to the extent that the transferee, purchaser or successor entity agrees to
continue the Plan.

      8.10. Evidence. Evidence required of anyone under the Plan may be by
certificate, affidavit, document or other information which the person relying
thereon considers pertinent and reliable, and signed, made or presented by the
proper party or parties.

      8.11. Action by the Company. Any action required of or permitted by the
Company under the Plan shall be by resolution of its Board, or by resolution of
a committee of the Board or by a person or persons authorized by resolution of
the Board or a committee.

      8.12. Severability. In the event any provisions of the Plan shall be held
to be illegal or invalid for any reason, such illegality or invalidity shall not
affect the remaining parts of the Plan, and the Plan shall be construed and
endorsed as if such illegal or invalid provisions had never been contained in
the Plan.
