whereby the Secured Party and Pledgor amended the SLA Note, the Credit Agreement

     WHEREAS, to induce the Secured Party to enter into the Omnibus Amendment,
and for other good and valuable consideration the receipt and sufficiency of
which are hereby acknowledged, the Pledgor has agreed to enter into this
Agreement and to grant to the Secured Party a security interest in the
Collateral (as hereinafter defined) to secure the full and punctual performance
of the Secured Obligations (as hereinafter defined);

     NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements hereinafter set forth, the parties hereto agree as
follows:

                                    ARTICLE 1
                                SECURITY INTEREST

     Section 1.01. The Pledge. As security for the prompt payment in full when
due (whether at stated maturity, by acceleration or otherwise) of the Secured
Obligations, whether now existing or hereafter from time to time arising, the
Pledgor hereby pledges and grants to the Secured Party, a Security Interest in
and lien on all of the Pledgor's right, title and interest in, to and under the
following property, whether now owned or hereafter acquired or hereafter coming
into existence and wherever located (all being collectively referred to herein
as the "Collateral"):

          (a) all Pledged Shares, together with, in each case:



                                       1
<PAGE>

          (i) all shares, securities, moneys or property representing a dividend
     on any of the Pledged Shares, or representing a distribution or return of
     capital upon or in respect of the Pledged Shares, or resulting from a
     split-up, revision, reclassification or other like change of the Pledged
     Shares or otherwise received in exchange therefor, and any subscription
     warrants, rights or options issued to the holders of, or otherwise in
     respect of, the Pledged Shares,

          (ii) without affecting the obligations of the Pledgor under any
     provision prohibiting such action hereunder or under the Credit Documents,
     in the event of any consolidation or merger in which the Pledgor is not the
     surviving corporation, all shares of each class of capital stock of the
     successor corporation (unless such successor corporation is the Pledgor
     itself) formed by or resulting from such consolidation or merger; and

          (iii) all Proceeds of and to any of the property of the Pledgor
     described in the preceding clauses of this Section 1.01 (including, without
     limitation, all causes of action, claims and warranties now or hereafter
     held by the Pledgor with respect to any of the items listed above) and, to
     the extent related to any property described in said clauses or such
     proceeds, all books, correspondence, credit files, records, invoices and
     other papers.

     Section 1.02. Financing Statements. Prior to or concurrently with the
execution and delivery of this Agreement, the Pledgor will promptly deliver
financing statements, continuation statements, assignments, certificates and
other documents with respect to the Collateral pursuant to the Uniform
Commercial Code, any other applicable law and otherwise as may be necessary or
appropriate (in the reasonable judgment of the Secured Party) to enable the
Secured Party to create, preserve, perfect or from time to time renew the
security interests granted hereby, in form satisfactory to the Secured Party,
and the Pledgor will pay the cost of filing the same in all public offices
wherever the Secured Party deems filing to be necessary or appropriate (in the
reasonable judgment of the Secured Party). The Pledgor grants the Secured Party
the right, at the Secured Party's option, to file any or all such financing
statements, continuation statements and other documents pursuant to the Uniform
Commercial Code, any other applicable law or otherwise, without the Pledgor's
signature, and irrevocably appoints the Secured Party as attorney in fact for
the Pledgor to execute any such statements and documents in the Pledgor's name
and to perform all other acts which the Secured Party deems appropriate to
perfect and continue the security interests conferred by this Agreement. The
Pledgor authorizes the Secured Party to file one or more Uniform Commercial Code
financing statements or continuation statements relating to all or any part of
the Collateral without the signature of the Pledgor where permitted by law. The
Secured Party may, at any time and from time to time, pursuant to the provisions
of this Section 1.02, file financing statements that describe the Collateral as
all assets and/or all personal property of the Pledgor or words of similar
effect and which contain any other information required by Article 9 of the

                                       2
<PAGE>


Uniform Commercial Code for the sufficiency or filing office acceptance of any
financing statement, including whether the Pledgor is an organization, the type
of organization and any organization identification number issued to the
Pledgor. The Pledgor agrees to promptly furnish any such information to the
Secured Party upon request. Any such financing statements may be filed at any
time in any jurisdiction deemed necessary or desirable by Secured Party.

     Section 1.03. Share Certificates. Prior to or concurrently with the
execution of this Agreement, the Pledgor will deliver to M&E Advisors L.L.C. as
Collateral Agent under the Collateral Agency Agreement certificates representing
the Pledged Shares and such certificates shall be duly endorsed in blank or
accompanied by stock powers duly executed by the Pledgor in blank, together with
any documentary tax stamps and any other documents necessary or desirable to
cause the Secured Party to have a good, valid and perfected pledge of, lien on
and security interest in the Pledged Shares, free and clear of any mortgage,
pledge, lien, security interest, hypothecation, assignment, charge, right,
encumbrance or restriction other than those arising under federal or state
Securities laws, those created hereunder and those created under the M&E Pledge.

     Section 1.04. Preservation of Rights. The Secured Party shall not be
required to take steps necessary to preserve any rights against prior parties to
any of the Collateral.

                                    ARTICLE 2
                    REPRESENTATIONS AND WARRANTIES OF PLEDGOR

     The Pledgor hereby represents and warrants to the Secured Parties that:

     Section 2.01. Title to Collateral. As of the date hereof, the Pledgor is
the sole beneficial owner of, and has good, valid and marketable title to, the
Collateral in which it purports to grant a security interest pursuant to Section
1.01, free from all Liens, except for the Security Interests in favor of the
Collateral Agent and the Secured Party, and has full right and power to grant
the Secured Party a Security Interest therein. Upon the execution and delivery
of this Agreement, and upon the filing of financing statements referred to in
Section 1.02 hereof, the Secured Party will have a good, valid and perfected
second lien and Security Interest in the Collateral, subject only to the
Collateral Agent's first priority lien and Security Interest in the Collateral.

     Section 2.02. Pledged Shares. The Pledged Shares will be duly authorized,
validly existing, fully paid and non-assessable and none of such Pledged Shares
are or will be subject to any contractual restriction, or any restriction under
the charter or by-laws of the respective issuer of such Pledged Shares, upon the
transfer of such Pledged Shares (except for any such restriction contained
herein or in the Credit Documents or arising under federal or state securities
laws). The Pledged Shares constitute all of the issued and outstanding shares of
capital stock of any class of License Sub beneficially owned by the Pledgor on
the date hereof (whether or not registered in the name of the Pledgor) and
Exhibit A correctly identifies, as of the date hereof, the issuer of such
Pledged Shares, the class and par value of the shares constituting such Pledged
Shares and the number of shares (and the registered owner thereof) represented
by each such certificate.


                                       3
<PAGE>

     Section 2.03. Names, Etc. The full and correct legal name, type of
organization, jurisdiction of organization, organizational ID number (if
applicable) and mailing address of the Pledgor as of the date hereof are
correctly set forth in Exhibit B.

period of four months prior to the date hereof, changed its location (as defined
in Section 9-307 of the Uniform Commercial Code), (ii) heretofore changed its
name, or (iii) heretofore become a "new debtor" (as defined in Section
9-102(a)(56) of the Uniform Commercial Code) with respect to a currently
effective security agreement previously entered into by any other Person.

     Section 2.05. Financing Statements. No Financing Statement (other than any
which may have been filed on behalf of the Secured Party) relating to any of the
Collateral is on file in any public office.

     Section 2.06. Non-Subordination. The obligations of the Pledgor under this
Agreement are not subordinated in any way to any other obligation of the Pledgor
or to the rights of others, except as provided in the Collateral Agency
Agreement.

     Section 2.07. True at Signing Date. Each of the representations and
warranties set forth in this Agreement or any other Loan Document shall be true
and correct as of the date hereof.

                                    ARTICLE 3
                        AFFIRMATIVE COVENANTS OF PLEDGOR

Maintain its location (as defined in Section 9-307 of the Uniform Commercial
Code) only at the location set forth in Exhibit B attached hereto, provided that

notice of any changes in location (as defined in Section 9-307 of the Uniform
Commercial Code).

     to the Collateral Agent such shares or securities so received by the
     Pledgor (together with the certificates for any such shares and securities
     duly endorsed in blank or accompanied by undated stock powers duly executed
     in blank), all of which thereafter shall be held by the Collateral Agent,
     pursuant to the terms of this Agreement and the Collateral Agency
     Agreement, as part of the Collateral or (y) take such other action as the
     Secured Party shall deem reasonably necessary or appropriate to duly record
     the Lien created hereunder in such shares, securities, moneys or property
     pursuant to Section 1.01;


                                       4
<PAGE>

          (b) give, execute, deliver, file, record, authorize or obtain all such
     financing statements, notices, instruments, documents, agreements, consents
     or other papers as may be necessary or desirable (in the reasonable
     judgment of the Secured Party) to create, preserve, perfect or validate the
     security interest granted pursuant hereto or to enable the Secured Party to
     exercise and enforce their rights hereunder with respect to such pledge and
     security interest; including, without limitation, causing any or all of the
     Share Collateral to be transferred of record into the name of the Secured
     Party or its nominee, provided that notices to account debtors in respect
     of any Accounts, Chattel Paper or General Intangibles and to obligors on
     Instruments shall be subject to the provisions of clause (d) below;

          (c) keep full and accurate books and records relating to the
     Collateral, and stamp or otherwise mark such books and records in such
     manner as the Secured Party may reasonably require in order to reflect the
     security interests granted by this Agreement; and

          (d) permit representatives of the Secured Party, upon reasonable
     notice, at any time during normal business hours to inspect and make
     abstracts from its books and records pertaining to the Collateral, and
     permit representatives of the Secured Party to be present at the Pledgor's
     place of business to receive copies of all communications and remittances
     relating to the Collateral, and forward copies of any notices or
     communications received by the Pledgor with respect to the Collateral, all

     continuing, the Pledgor shall have the right to exercise all voting,
     consensual and other powers of ownership pertaining to the Share Collateral
     for all purposes not inconsistent with the terms of this Agreement, the
     Credit Agreement or any other Credit Document or other instrument or
     agreement referred to herein or therein, provided that the Pledgor agrees
     that it will not vote the Share Collateral in any manner that is
     inconsistent with the terms of this Agreement, the Credit Agreement or any
     such other Credit Document or other instrument or agreement; and the
     Secured Party shall execute and deliver to the Pledgor or cause to be

     executed and delivered to the Pledgor all such proxies, powers of attorney,
     dividend and other orders, and all such instruments, without recourse, as
     the Pledgor may reasonably request for the purpose of enabling the Pledgor
     to exercise the rights and powers that it is entitled to exercise pursuant
     to this Section 3.04.

          (c) Unless and until an Event of Default has occurred and is
     continuing, the Pledgor shall be entitled to receive and retain any and all
     dividends and distributions on the Share Collateral.

     Section 3.05. Further Assurances. From time to time, upon the written
request of the Secured Party, execute and deliver such further documents and do

                                    ARTICLE 4
                          NEGATIVE COVENANTS OF PLEDGOR

Deposit Account, Electronic Chattel Paper, Investment Property or
Letter-of-Credit Right constituting part of the Collateral.

     Section 4.03. FCC Licenses. Unless permitted by the Collateral Agent, the
Pledgor will not suffer (a) any FCC License to be owned or acquired by any
Person other than License Sub or (b) License Sub to (i) be partially or wholly

                   RIGHTS UPON OCCURRENCE OF EVENTS OF DEFAULT

     Section 6.01. Rights of the Collateral Agent. Upon the occurrence and
continuance of any Event of Default, the Collateral Agent shall have the right,
subject to the provisions of Section 7.06:

          (a) to declare all of the Secured Obligations to be immediately due
     and payable, whereupon all such Secured Obligations shall become
     immediately due and payable without presentment, demand, protest or further
     notice of any kind, all of which are hereby expressly waived by the
     Pledgor, anything contained herein to the contrary notwithstanding;

          (b) to exercise any one or more of the rights and remedies exercisable
     by the Collateral Agent under other provisions of this Agreement or
     exercisable by a secured party under the Uniform Commercial Code as in
     effect in Illinois (whether or not said Uniform Commercial Code is in
     effect in the jurisdiction where the rights and remedies are asserted) or
     under any other applicable law;

          (c) to exercise, in the name of the Pledgor or in the name of the
     Collateral Agent, such rights and powers with respect to the Collateral as
     the Pledgor might exercise, including the right to demand, sue, collect or
     receive any money or property at any time payable or receivable on account
     of or in exchange for any of the Collateral;


                                       7
<PAGE>


               (d) whether or not Secured Party exercises any available right to
          declare any Secured Obligation due and payable or seek or pursue any
          other relief or remedy available to it under applicable law or under
          this Agreement, the Credit Agreement or any other Credit Document or
          other instrument or agreement relating to such Secured Obligation, (i)
          any and all Pledged Shares will be, at the option of the Secured
          Party, registered on the books of the relevant company in the name of
          the Collateral Agent and (ii) all dividends and other distributions on
          the Share Collateral shall be paid directly to the Collateral Agent
          and retained by it on behalf of the Secured Party as part of the Share
          Collateral, subject to the terms of this Agreement, and, if the
          Secured Party shall so request in writing, the Pledgor agrees to
          execute and deliver to the Collateral Agent appropriate additional
          dividend, distribution and other orders and documents to that end,
          provided that if such Event of Default is cured, any such dividend or
          distribution theretofore paid to the Collateral Agent shall, upon
          request of the Pledgor (except to the extent theretofore applied to
          the Secured Obligations), be returned by the Collateral Agent to the
          Pledgor; and

               (e) to sell, lease, assign or otherwise dispose of all or a part
          of the Collateral that shall then be or shall thereafter come into the
          possession, custody or control of the Collateral Agent at such place
          or places that the Secured Party deems best, and for cash or for
          credit or for future delivery (without thereby assuming any credit
          risk), at public or private sale, without demand of performance or
          notice of intention to effect any such disposition or of the time or
          place thereof (except such notice as is required below or by
          applicable statute and cannot be waived), and the Secured Party or any
          other individual or entity may be the purchaser, lessee, assignee or
          recipient of any or all of the Collateral so disposed of at any public
          sale (or, to the extent permitted by law, at any private sale) and
          thereafter hold the same absolutely, free from any claim or right of
          whatsoever kind, including any right or equity of redemption
          (statutory or otherwise), of the Pledgor, any such demand, notice and
          right or equity being hereby expressly waived and released. Unless the
          Collateral is perishable or threatens to decline speedily in value or
          is of a type customarily sold on a recognized market, the Secured
          Party will give the Pledgor at least five (5) days' prior written
          notice of the time and place of any public sale thereof or of the time
          after which any private sale or any other intended disposition thereof
          is to be made, which notice shall constitute reasonable notice. The
          Secured Party 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 sale may be so
          adjourned.

     The Pledgor recognizes that, by reason of certain prohibitions contained in
the Securities Act of 1933, as amended, and applicable state securities laws,
the Secured Party may be compelled, with respect to any sale of all or any part


                                       8
<PAGE>

of the Collateral, to limit purchasers to those who will agree, among other
things, to acquire the Collateral for their own account, for investment and not
with a view to the distribution or resale thereof. The Pledgor acknowledges that
any such private sales may be at prices and on terms less favorable to the
Secured Party than those obtainable through a public sale without such
restrictions, and, notwithstanding such circumstances, agree that any such
private sale shall be deemed to have been made in a commercially reasonable
manner and that the Secured Party shall have no obligation to engage in public
sales and no obligation to delay the sale of any Collateral for the period of
time necessary to permit the respective issuer to register it for public sale.

     Section 6.02. Deficiency. If the Proceeds or sale, collection or other
realization of or upon the Collateral pursuant to this Article 6 are
insufficient to cover the costs and expenses or such realization and the payment
in full of the Secured Obligations, the Pledgor shall remain liable for any
deficiency.

     Section 6.03. Private Sale. The Secured Party shall not incur any liability
as a result of a private sale of the Collateral, or any part thereof, at any
private sale pursuant to Section 6.03 conducted in a commercially reasonable
manner. The Pledgor hereby waives any claims against the Secured Party arising
by reason of the fact that the price at which the Collateral may have been sold
at such a private sale was less than the price that might have been obtained at
a public sale or was less than the aggregate amount of the Secured Obligations,
even if the Secured Party accepts the first offer received and does not offer
the Collateral to more than one offeree, so long as such private sale is
conducted in a commercially reasonable manner.

     Section 6.04. Application of Proceeds. Except as otherwise herein expressly
provided, the Proceeds of any collection, sale or other realization of all or
any part of the Collateral pursuant hereto shall be applied by the Secured Party
in the following order of priority:

          First, to the payment of all costs and expenses of such collection,
     sale or other realization (including reasonable out-of-pocket costs and
     expenses of the Secured Parties and fees and expenses of its agents and
     counsel, and all expenses, liabilities and advances made or incurred in
     connection therewith);

          Next, to the payment in full of all Secured Obligations, in each case
     equally and ratably in accordance with the respective amounts thereof then
     due and owing or as the Secured Parties holding the same may otherwise
     agree; and

          Finally, to the payment to the Pledgor or its successors and assigns,
     unless otherwise provided by law or directed by a court of competent
     jurisdiction.

          Section 6.05. Attorney-in-Fact. Without limiting any rights or powers
     granted by this Agreement to the Secured Party, upon the occurrence and
     during the continuance of any Event of Default the Secured Party is hereby
     appointed the attorney-in-fact of the Pledgor for the purpose of carrying
     out the provisions of this Article 6 and taking any action and executing
     any instruments that the Secured Party may deem necessary or advisable to
     accomplish the purposes hereof, which appointment as attorney-in-fact is



                                       9
<PAGE>

     irrevocable and coupled with an interest. Without limiting the generality
     of the foregoing, so long as the Secured Party shall be entitled under this
     Article 6 to make collections in respect of the Collateral, the Secured
     Party shall have the right and power to receive, endorse and collect all
     checks made payable to the order of the Pledgor representing any dividend,
     payment or other distribution in respect of the Collateral or any part
     thereof and to give full discharge for the same.

          Section 6.06. Right of the Secured Party To Appoint Receiver. Without
     limiting any other rights granted to the Secured Party under this
     Agreement, the Secured Party shall have the right to apply for and have a
     receiver appointed by a court of competent jurisdiction in any action taken
     by the Secured Party to enforce its rights and remedies hereunder in order
     to manage, protect and preserve the Collateral and continue the operation
     of the business of the Pledgor and to collect all revenues and profits
     thereof and apply the same to the payment of all expenses and other charges
     of such receivership including the compensation of the receiver and to the
     payments as aforesaid until a sale or other disposition of such Collateral
     shall be finally made and consummated.

          Section 6.07. Names. The Pledgor shall not change its name from the
     name shown as its current legal name on Exhibit B hereto without at least
     thirty (30) days' prior written notice to the Collateral Agent.

                                    ARTICLE 7
                            MISCELLANEOUS PROVISIONS

          Section 7.01. Additional Actions and Documents. The Pledgor hereby
     agrees to take or cause to be taken such further actions, to execute,
     deliver and file or cause to be executed, delivered and filed such further
     documents and instruments, and to obtain such consents, as may be necessary
     or as may be reasonably requested in order to fully effectuate the
     purposes, terms and conditions of this Agreement, whether before, at or
     after the closing of transactions contemplated hereby or the occurrence of
     an Event of Default hereunder.

          Section 7.02. Expenses. The Pledgor agrees to reimburse the Secured
     Party for all reasonable costs and expenses incurred by them, including,
     without limitation, the reasonable fees and expenses of legal counsel, in
     connection with (a) any Event of Default and any enforcement or collection
     proceeding resulting therefrom, including, without limitation, all manner
     of participation in or other involvement with (i) performance by the
     Secured Party of any obligations of the Pledgor in respect of the
     Collateral that the Pledgor has failed or refused to perform, (ii)
     bankruptcy, insolvency, receivership, foreclosure, winding up or
     liquidation proceedings, or any actual or attempted sale, or any exchange,
     enforcement, collection, compromise or settlement in respect of any of the
     Collateral, and for the care of the Collateral and defending or asserting
     rights and claims of the Secured Party in respect thereof, by litigation or
     otherwise, including expenses of insurance, (iii) judicial or regulatory
     proceedings and (iv) workout, restructuring or other negotiations or
     proceedings (whether or not the workout, restructuring or transaction
     contemplated thereby is consummated) and (b) the enforcement of this
     Section 7.02, and all such costs and expenses shall be Secured Obligations


                                       10
<PAGE>

     entitled to the benefits of the collateral security provided pursuant to
     Section 1.01; provided, however, the Pledgor shall only be required to
     reimburse the Secured Party under this Section 7.02 for the reasonable
     costs, fees and expenses of legal counsel for the Secured Party.

          Section 7.03. Notices. All notices, demands, requests, or other

     Section 7.04. Waiver of Right to Judicial Hearing. The Pledgor hereby
waives any right it may have to a judicial hearing prior to the exercise of any
right or remedy provided to the Secured Party under this Agreement, and waives
its rights, if any, to set aside or invalidate any sale duly consummated in
accordance with the foregoing provisions hereof on the grounds (if such be the
case) that the sale was consummated without a prior judicial hearing. The
Pledgor's waivers under this paragraph have been made voluntarily and knowingly
and after the Pledgor has been apprised and counseled by its attorneys as to the
nature of such rights and as to the Pledgor's possible alternative rights.

     Section 7.05. Waiver by the Secured Party. No waiver by the Secured Party
of, or consent by the Secured Party to, a variation from the requirements of any
provision of this Agreement shall be effective unless made in a written
instrument duly executed on behalf of the Secured Party by its duly authorized
officer, and any such waiver shall be limited solely to those rights or
conditions expressly waived. No failure on the part of the Secured Party to
exercise, and no course of dealing with respect to, and no delay in exercising,
any right, power or remedy hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise by the Secured Party of any right, power or
remedy hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. The remedies herein are cumulative and are
not exclusive of any remedies provided by law.

     Section 7.06. Governmental Approvals. The Secured Party acknowledges that
in connection with any exercise by them of their rights hereunder to dispose of
or operate under the licenses, permits, or other approvals covered hereby, it
may be necessary to obtain the prior consent or approval of certain governmental
authorities. Upon the exercise by the Secured Party of any power, right,
privilege or remedy pursuant to this Agreement which requires any consent,
approval, registration, qualification or authorization of any governmental
authority or instrumentality, including, but not limited to, the Federal
Communications Commission, the Pledgor will execute and deliver, or will cause
the execution and delivery of, all applications, certificates, instruments and
other documents and papers that the Secured Party may be required to obtain for
such governmental consent, approval, registration, qualification or
authorization.

     Section 7.07. Release of Collateral. Promptly following performance and
payment in full of the Secured Obligations, the Security Interest created hereby
shall terminate, and the Secured Party shall execute and deliver such documents,
at the Pledgor's expense, as are necessary to release the Secured Party's
Security Interest in the Collateral.

     Section 7.08. Benefit and Assignment. This Agreement shall be binding upon
and shall inure to the benefit of the Pledgor and the Secured Party and their
respective successors and assigns as permitted hereunder. This Agreement may not
be assigned by the Pledgor without the prior written consent of the Secured
Party. In the event of a sale or assignment by the Secured Party of all or any
part of the interests in the Credit Documents, the Secured Party may assign and


                                       12
<PAGE>

transfer their rights and interests under this Agreement in whole or in part to
the purchaser or purchasers of such interests in the Credit Documents, whereupon
such purchaser or purchasers shall become vested with all of the powers and
rights given to the Secured Party hereunder, and shall be deemed to be Secured
Party for all purposes hereunder, and the predecessor Secured Party shall
thereafter be forever released and fully discharged from any liability or
responsibility hereunder with respect to the rights and interests so assigned.

     Section 7.09. Severability. If fulfillment of any provision of this
Agreement, or performance of any transaction related hereto, at the time such
fulfillment or performance shall be due, shall transcend the limits of validity
prescribed by law, then the obligation to be fulfilled or performed shall be
reduced to the limit of such validity.

     Section 7.10. Survival. It is the express intention and agreement of the
parties hereto that all covenants and agreements, statements, representations,
warranties and indemnities made by the Pledgor shall survive the execution and
delivery of this Agreement.

     Section 7.11. Rights Cumulative. The rights and remedies of the Secured
Party described herein are cumulative and nonexclusive of any other rights or
remedies which the Secured Party otherwise would have at law or in equity or
otherwise. No notice to or demand on the Pledgor in any case shall entitle the
Pledgor to any other notice or demand in similar or other circumstances.

     Section 7.12. Entire Agreement, Modification. This Agreement and the
exhibits hereto constitute the entire agreement of the parties hereto with
respect to the transactions contemplated herein, and supersede all prior oral
and written agreements with respect to the transactions contemplated herein, and
may not be modified, deleted or amended in any manner except by agreement in
writing executed by the parties.

     Section 7.13. Termination. This Agreement shall continue in force until the
date on which the Secured Obligations shall have been paid and discharged in
full and the Commitments of the Secured Party under the Credit Documents have
terminated.

     Section 7.14. Construction. This Agreement, the rights and obligations of
the parties hereto, and any claims or disputes relating thereto, shall be
governed by and construed in accordance with the laws of the State of Illinois.
Each party hereto hereby acknowledges that all parties hereto participated
equally in the negotiation and drafting of this Agreement and that, accordingly,
no court construing this Agreement shall construe it more stringently against
one party than against the other.

     Section 7.15. Pronouns. All pronouns and any variations thereof shall be
deemed to refer to the masculine, feminine, neuter, singular or plural, as the
identity of the person or entity may require.

     Section 7.16. Headings. Section and subsection headings contained in this
Agreement are inserted for convenience of reference only, shall not be deemed to
be a part of this Agreement for any purpose, and shall not in any way define or
affect the meaning, construction or scope of any of the provisions hereof.
Unless otherwise indicated or apparent from the context, all references to
Articles and Sections herein contained are to Articles and Sections of this
Agreement.

     Section 7.17. Payments. If any payment or performance of obligations under
this Agreement becomes due on a day other than a Business Day, the due date
shall be extended to the next succeeding Business Day, and interest thereon (if
applicable) shall be payable at then applicable rate during such extension.

     Section 7.18. Execution. To facilitate execution, this Agreement may be
executed in as many counterparts as may be required; and it shall not be
necessary that the signatures of, or on behalf of, each party, or that the
signatures of all persons required to bind any party, appear on each
counterpart; but it shall be sufficient that the signature of, or on behalf of,
each party, or that the signatures of the persons required to bind any party,
appear on one or more of the counterparts. All counterparts shall collectively
constitute a single agreement. It shall not be necessary in making proof of this
Agreement to produce or account for any particular number of counterparts; but
rather any number of counterparts shall be sufficient so long as those
counterparts contain the respective signatures of, or on behalf of, all of the
parties hereto. Facsimile signatures to this Agreement shall have the same
binding effect as manual signatures hereto.
