         its rights hereunder with respect to such pledge and security interest;

              (c) keep full and accurate books and records relating to the
         Collateral, and stamp or otherwise mark such books and records in order

         notices or communications received by the Obligor with respect to the

upon such deposit and at all times thereafter such amounts shall not constitute
Collateral.

              (3) The Holdings Collateral Agent (acting upon the instructions of
the Required Creditors) shall be entitled to exercise all rights of the "Lender"
under the Intercompany Note to the exclusion of the Obligor (including, without

compromise or settlement at the direction of the Required Creditors deemed
desirable with respect to any of the Collateral and may extend the time of
payment, arrange for payment in installments, or otherwise modify the terms of,
any of the Collateral at the direction of the Required Creditors;

                                        5
<PAGE>

              (d) the Holdings Collateral Agent shall have all of the rights and
remedies with respect to the Collateral of a secured party under the Uniform
Commercial Code (whether or not said Code is in effect in the jurisdiction where
the rights and remedies are asserted) and such additional rights and remedies to
which a secured party is entitled under the laws in effect in any jurisdiction
where any rights and remedies hereunder may be asserted, including, without
limitation, the right, to the maximum extent permitted by law, to exercise all
voting, consensual and other powers of ownership pertaining to the Collateral as
if the Holdings Collateral Agent were the sole and absolute owner thereof (and
the Obligor agrees to take all such action as may be appropriate to give effect
to such right);

              (e) the Holdings Collateral Agent may, at the direction of the
Required Creditors, in its name or in the name of the Obligor or otherwise,
demand, sue for, collect or receive any money or property at any time payable or
receivable on account of or in exchange for any of the Collateral, but shall be
under no obligation to do so; and

              (f) the Holdings Collateral Agent may, with respect to the
Collateral or any part thereof that shall then be or shall thereafter come into
the possession, custody or control of the Holdings Collateral Agent, any other
Secured Party or any of their respective agents, upon ten (10) Business Days
prior written notice to the Obligor of the time and place, sell, lease, assign
or otherwise dispose of all or any part of such Collateral, at such place or
places as the Holdings Collateral Agent deems best, and for cash or for credit
or for future delivery (without thereby assuming any credit risk or liability),
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 as
provided above and such notice as is required above or by applicable statute
that cannot be waived), and upon such other terms as the Holdings Collateral
Agent, at the direction of the Required Creditors, may reasonably deem
commercially reasonable, and the Holdings Collateral Agent or any other Secured
Party or anyone else 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 Obligor, any such demand, notice
and right or equity being hereby expressly waived and released. The Holdings
Collateral Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned

                                        6
<PAGE>

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 proceeds of each collection, sale or other disposition under
this Section 4.5 shall be applied in accordance with Section 4.9 hereto.

              The Obligor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, and applicable state
securities laws, the Holdings Collateral Agent may be compelled, with respect to
any sale of all or any part 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
Obligor acknowledges that any such private sales may be at prices and on terms
less favorable to the Holdings Collateral Agent than those obtainable through a
public sale without such restrictions. The parties hereto agree that any such
private sale shall be made in a commercially reasonable manner and that the
Holdings Collateral Agent 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 or issuers thereof to register it for
public sale.

              Section 4.6 DEFICIENCY. If the proceeds of sale, collection or
other realization of or upon the Collateral pursuant to Section 4.5 are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Secured Obligations, the Obligor shall remain liable for any
deficiency to the extent the Obligor is obligated under this Agreement.

              Section 4.7 REMOVALS, ETC. Without at least 30 days' prior written
notice to the Holdings Collateral Agent, the Obligor shall not (i) maintain any
of its books and records with respect to the Collateral at any office, or
maintain its principal place of business at any place other than at the address
indicated beneath the signature of Holdings to the Credit Agreement or (ii)
change its name, or the name under which it does business, from the name shown
on the signature pages hereto.

              Section 4.8 PRIVATE SALE. The Holdings Collateral Agent and the
other Secured Parties shall incur no liability as a result of the sale of the
Collateral, or any part thereof, at any private sale pursuant to Section 4.5
conducted in a commercially reasonable manner. The Obligor hereby waives any
claims against the

                                        7
<PAGE>

Holdings Collateral Agent or any other 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 Holdings Collateral Agent accepts the first offer received and
does not offer the Collateral to more than one offeree.

              Section 4.9 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, and any other cash at the
time held by the Holdings Collateral Agent under this Section 4, shall be
applied by the Holdings Collateral Agent in accordance with Section 16 of the
Intercreditor Agreement.

              Section 4.10 ATTORNEY-IN-FACT. Without limiting any rights or
powers granted by this Agreement to the Holdings Collateral Agent while no
Intercreditor Agreement Event of Default has occurred and is continuing, upon
the occurrence and during the continuance of any Intercreditor Agreement Event
of Default, the Holdings Collateral Agent is hereby appointed the
attorney-in-fact of the Obligor for the purpose of carrying out the provisions
of this Section 4 and taking any action and executing any instruments that the
Holdings Collateral Agent may at the direction of the Required Creditors deem
necessary or advisable to accomplish the purposes hereof, which appointment as
attorney-in-fact is irrevocable and coupled with an interest. Without limiting
the generality of the foregoing, so long as the Holdings Collateral Agent shall
be entitled under this Section 4 to make collections in respect of the
Collateral, the Holdings Collateral Agent shall have the right and power to
receive, endorse and collect all checks made payable to the order of the Obligor
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 4.11. PERFECTION. Prior to or concurrently with the
execution and delivery of this Agreement, the Obligor shall (i) file such
financing statements and other documents in such offices as the Holdings
Collateral Agent may request to perfect the security interests granted by
Section 3 of this Agreement, (ii) deliver to the Holdings Collateral Agent the
Intercompany Note, accompanied by undated bond power duly executed in blank and
(iii) shall deliver to the Holdings Collateral Agent a UCC-1 financing statement
for filing, in each jurisdiction requested by the Hold-

                                        8
<PAGE>

ings Collateral Agent, at the direction of the Required Creditors, naming the
Obligor as debtor and duly signed by the Obligor.

              Section 4.12 TERMINATION. When the Intercreditor Agreement
Termination Date shall have occurred, this Agreement shall terminate, and the
Holdings Collateral Agent shall forthwith cause to be assigned, transferred and
delivered, against receipt but without any recourse, warranty or representation
whatsoever, any remaining Collateral and money received in respect thereof, to
or on the order of the Obligor. Upon the request, and at the expense of the
Obligor, the Holdings Collateral Agent shall execute and deliver all such
documentation necessary to release the pledge created pursuant to this
Agreement.

              Section 4.13 FURTHER ASSURANCES. The Obligor agrees that, from
time to time upon the written request of the Holdings Collateral Agent, the
Obligor will execute and deliver such further documents and do such other acts
and things as the Holdings Collateral Agent may, at the direction of the
Required Creditors, request in order to fully effect the purposes of this
Agreement.

              SECTION 5. MISCELLANEOUS.

              Section 5.1. NOTICES. All notices, requests and other
communications provided for herein shall be given or made in writing in the
manner set forth in Section 24 of the Intercreditor Agreement. Unless otherwise
changed in accordance with the Intercreditor Agreement by the respective parties
hereto, all notices, requests and other communications to each party hereto
shall be sent to the address for notices of such party set forth on the
signature pages hereto.

              Section 5.2. NO WAIVER. No failure on the part of the Holdings
Collateral Agent or any other 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 Holdings Collateral Agent or any other 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.

                                        9

              Section 5.3. AMENDMENTS, ETC. The terms of this Agreement may be
waived, altered or amended only by an instrument in writing duly executed by the
Obligor and the Holdings Collateral Agent (with the consent of the Required
Creditors in accordance with the Intercreditor Agreement). Any such amendment or
waiver shall be binding upon the Holdings Collateral Agent and each other
Secured Party, each holder of any of the Secured Obligations and the Obligor.

              Section 5.4. EXPENSES. The Obligor agrees to reimburse upon
demand to the Holdings Collateral Agent and each of the other Secured Parties
for all reasonable costs and expenses (including disbursements) of the Holdings
Collateral Agent and such other Secured Parties (including, without limitation,
the reasonable fees and expenses of legal counsel) incurred in connection with
(i) the preparation, delivery, administration, execution and amendment of this
Agreement, (ii) any Default and any enforcement, collection proceeding or sale
resulting therefrom, including, without limitation, all manner of participation

foreclosure, winding up or liquidation proceedings, or any actual or attempted

respect thereof, by litigation or otherwise, including expenses of insurance,
(y) judicial or regulatory proceedings and (z) workout, restructuring or other

transaction contemplated thereby is consummated) and (iii) the enforcement of
this Section 5.4, and all such costs and expenses shall be Secured Obligations
entitled to the benefits of the collateral security provided pursuant to Section
3.

              Section 5.5. SUCCESSORS AND ASSIGNS. This Agreement shall be
binding upon and inure to the benefit of the respective successors and assigns
of the Obligor, the Holdings Collateral Agent, each of the other Secured Parties
and each holder of any of the Secured Obligations (provided, however, that the
Obligor shall not assign or transfer its rights hereunder without the prior
written consent of the Holdings Collateral Agent).

              Section 5.6. COUNTERPARTS. This Agreement may be executed in
