Mortgagee as loss payee and (ii) provide that all property losses insured
against involving a claim or claims with respect to a single Casualty in excess
of $100,000 shall be adjusted by the Mortgagor, subject to the Mortgagee's
rights pursuant to Section 3.03 hereof and the Security Agreement. The liability

material change thereof shall be effective until at least 30 days after receipt

under this Section (or to pay the Insurance Premiums for such Insurance Policies
as and when due), the Mortgagee shall have the right (but not the obligation) to
obtain such Insurance Policies and pay the Insurance Premiums therefor. If the
Mortgagee obtains such Insurance Policies or pays the premiums therefor, upon
demand, the Mortgagor shall reimburse the Mortgagee for its reasonable expenses
in connection therewith (including reasonable attorneys' fees and expenses),

policy allocated to the Property, and (B) any sublimits in such blanket policy
applicable to the Property, which sublimits shall not be less than the amounts
required pursuant to this Section, (ii) any such blanket insurance policy shall

than that which would have been afforded under a separate policy relating only
to the Property.

concurrent in form or contributing in the event of loss with the insurance
required under this Section, unless (i) the policies providing such additional
or separate insurance are submitted to the Mortgagee for its approval, which
approval shall not be unreasonably withheld, (ii) the insurers under such
policies and the terms thereof are approved by the Mortgagee, which approval
shall not be unreasonably withheld and (iii) the Mortgagee and the other Secured
Parties are included in such policies as loss payees or additional insureds.

         SECTION 5.3. WAIVERS BY THE MORTGAGOR. To the fullest extent permitted
under applicable law, the Mortgagor shall not assert, and hereby irrevocably
waives, any right or defense the Mortgagor may have under any statute or rule of
law or equity now or hereafter in effect relating to (i) appraisement,
valuation, homestead exemption, extension, moratorium, stay, statute of
limitations, redemption, marshaling of the Mortgaged Property or the other
assets of the Mortgagor, sale of the Mortgaged Property in any order or notice

Secured Obligations under or with respect to this Mortgage or the other
Collateral Documents as it relates to any Trust Property; or (vii) the right of
the Mortgagee to foreclose this Mortgage in its own name as Collateral Agent on
behalf of all of the Secured Parties by judicial action as the real party in
interest without the necessity of joining any other Secured Party. Nothing in
this Section shall be construed to limit any rights, including rights to notice,
afforded to the Mortgagor under this Mortgage or the other Financing Documents.

         SECTION 5.4. JURISDICTION AND PROCESS. (a) To the fullest extent
permitted under applicable law, in any suit, action or proceeding arising out of
or relating to this Mortgage or any other Collateral Document as it relates to
any Mortgaged Property, the Mortgagor (i) irrevocably consents to the
non-exclusive jurisdiction of any state or federal court sitting in the State in

which it may now or hereafter have to the jurisdiction of such court over, the
venue of such court for or the convenience of such court as the forum for any
such suit, action or proceeding; and (ii) irrevocably consents to the service of
(A) any process in any such suit, action or proceeding, or (B) any notice
relating to any sale, or the exercise of any other remedy by the Mortgagee
hereunder by mailing a copy of such process or notice by United States

                                       24
<PAGE>

          (b) Nothing in this Section shall affect the right of the Mortgagee or
the Mortgagor to bring any suit, action or proceeding arising out of or relating
to this Mortgage or any other Financing Document in any court having
jurisdiction under the provisions of any other Financing Document or applicable
law or to serve any process, notice of sale or other notice in any manner
permitted by any other Financing Document or applicable law.

         SECTION 5.5. SALES. Except as otherwise provided herein, to the fullest
extent permitted under applicable law, at the election of the Mortgagee, the
following provisions shall apply to any sale of the Mortgaged Property
hereunder, whether made pursuant to the power of sale hereunder, any judicial
proceeding or any judgment or decree of foreclosure or sale or otherwise:

          (a) The Mortgagee or the court officer (whichever is the Person
conducting any sale) may conduct any number of sales from time to time. The
power of sale hereunder or with respect hereto shall not be exhausted by any
sale as to any part or parcel of the Mortgaged Property which is not sold,
unless and until the Secured Obligations shall have been paid in full, and shall
not be exhausted or impaired by any sale which is not completed or is defective.
Any sale may be as a whole or in part or parcels and, to the fullest extent
permitted under applicable law, the Mortgagor hereby waives its right to direct
the order in which the Mortgaged Property or any part or parcel thereof is sold.

          (b) Any sale may be postponed or adjourned by public announcement at
the time and place appointed for such sale or for such postponed or adjourned
sale without further notice.

          (c) After each sale, the Person conducting such sale shall execute and
deliver to the purchaser or purchasers at such sale a good and sufficient
instrument or instruments granting, conveying, assigning, transferring and
delivering all right, title and interest of the Mortgagor in and to the
Mortgaged Property sold and shall receive the proceeds of such sale up to the
Maximum Secured Amount and apply the same as provided in Section 5.06. The
Mortgagor hereby irrevocably appoints the Person conducting such sale as the
attorney-in-fact of the Mortgagor (with full power to substitute any other
Person in its place as such attorney-in-fact) to act in the name of the
Mortgagor or, at the option of the Person conducting such sale, in such Person's
own name, to make without warranty by such Person any conveyance, assignment,
transfer or delivery of the Mortgaged Property sold, and to execute, acknowledge
and deliver any instrument of conveyance, assignment, transfer or delivery or
other document in connection therewith or to take any other action incidental
thereto, as the Person conducting such sale shall deem appropriate in its
discretion; and the Mortgagor hereby irrevocably authorizes and directs any
other Person to rely and act upon the foregoing appointment and a certificate of
the Person conducting such sale that such Person is authorized to act hereunder.
Nevertheless, upon the request of such attorney-in-fact the Mortgagor shall
promptly execute, acknowledge and deliver any documentation which such
attorney-in-fact may require for the purpose of ratifying, confirming or
effectuating the powers granted hereby or any such conveyance, assignment,
transfer or delivery by such attorney-in-fact.

          (d) Any statement of fact or other recital made in any instrument
referred to in Section 5.05(c) given by the Person conducting any sale as to the
non-payment of any Secured Obligation, the occurrence of any Event of Default,
the amount of the Secured Obligations due and payable, the request to the
Mortgagee to sell, the notice of the time, place and terms of sale and the


                                       25
<PAGE>

Mortgaged Property to be sold having been duly given, the refusal, failure or
inability of the Mortgagor to act, the appointment of any substitute or
successor agent or any other act or thing having been taken or done by the
Mortgagor, the Mortgagee or any other Person shall be taken as conclusive and
binding, absent manifest error, against all other Persons as evidence of the
truth of the facts so stated or recited. The Person conducting any sale may
appoint or delegate any other Person as agent to perform any act necessary or
incident to such sale, including the posting of notices and the conduct of such
sale, but in the name and on behalf of the Person conducting such sale.

          (e) The receipt by the Person conducting any sale of the purchase
money paid at such sale shall be sufficient discharge therefor to any purchaser
of any Mortgaged Property sold, and no such purchaser, or its representatives,
grantees or assigns, after paying such purchase price and receiving such
receipt, shall be bound to see to the application of such purchase price or any
part thereof upon or for any trust or purpose of this Mortgage or the other
Financing Documents or, in any manner whatsoever, be answerable for any loss,
misapplication or nonapplication of any such purchase money or be bound to
inquire as to the authorization, necessity, expediency or regularity of such
sale.

          (f) Subject to mandatory provisions of applicable law, any sale shall
operate to divest all of the estate, right, title, interest, claim and demand
whatsoever, whether at law or in equity, of the Mortgagor in and to the
Mortgaged Property sold, and shall be a perpetual bar both at law and in equity
against the Mortgagor and any and all Persons claiming such Mortgaged Property
or any interest therein by, through or under the Mortgagor.

          (g) At any sale, the Mortgagee may bid for and acquire the Mortgaged
Property sold and, in lieu of paying cash therefor, may make settlement for the
purchase price by causing the Secured Parties to credit against the Secured
Obligations, including the expenses of the sale and the cost of any enforcement
proceeding hereunder, the amount of the bid made therefor to the extent
necessary to satisfy such bid.

          (h) If the Mortgagor or any Person claiming by, through or under the
Mortgagor shall transfer or fail to surrender possession of the Mortgaged
Property, after the exercise by the Mortgagee or a Receiver of its remedies
under Section 5.02(a)(vi) or after any sale of the Mortgaged Property pursuant
hereto, then to the fullest extent permitted under applicable law, the Mortgagor
or such Person shall be deemed a tenant at sufferance of the purchaser at such
sale, subject to eviction by means of summary process for possession of land, or
subject to any other right or remedy available hereunder or under applicable
law.

          (i) Upon any sale, it shall not be necessary for the Person conducting
such sale to have any Mortgaged Property being sold present or constructively in
its possession.

          (j) If a sale hereunder shall be commenced by the Mortgagee, the
Mortgagee may at any time before the sale abandon the sale, and may institute
suit for the collection of the Secured Obligations or for the foreclosure of
this Mortgage; or if the Mortgagee shall institute a suit for collection of the
Secured Obligations or the foreclosure of this Mortgage, the Mortgagee may at


                                       26
<PAGE>

any time before the entry of final judgment in said suit dismiss the same and
sell the Mortgaged Property in accordance with the provisions of this Mortgage.

         SECTION 5.6. PROCEEDS. Except as otherwise provided herein or required
under any mandatory provision of applicable law, the proceeds of any sale of, or
other realization upon, the Mortgaged Property hereunder up to the Maximum
Secured Amount, whether made pursuant to the power of sale hereunder, any
judicial proceeding, any judgment or decree of foreclosure or sale or otherwise
shall be paid into the applicable Collateral Account and applied and paid as
follows:

          (a) FIRST: to the payment of all expenses of such sale or other
realization, including compensation for the Person conducting such sale (which
may include the Mortgagee), the cost of title searches, foreclosure certificates
and attorneys' fees and expenses incurred by such Person, together with interest
on any such expenses paid by such Person at the Post-Default Rate for Revolving
Loans from the date paid by such Person through the date repaid to such Person;

          (b) SECOND: to the payment of the expenses and other amounts payable
under Sections 4.04 or 7.02; and

          (c) THIRD: to the payment of the other Secured Obligations in the
order and priority set forth in Section 20 of the Security Agreement, until all
Secured Obligations shall have been paid in full; and

          (d) FOURTH: to pay to the Mortgagor or its successors and assigns, or
as a court of competent jurisdiction may direct, any surplus then remaining from
such proceeds.

         SECTION 5.7. ASSIGNMENT OF LEASES. (a) To the fullest extent permitted
under applicable law, subject to Section 5.07(d), the assignments of the Leases
and the Rents under Granting Clauses VI and VII are and shall be present,
absolute and irrevocable assignments by the Mortgagor to the Mortgagee and,
subject to the license to the Mortgagor under Section 5.07(b), the Mortgagee or
a Receiver appointed pursuant to Section 5.02(a)(v) (whichever is the Person
exercising the rights under this Section) shall have the absolute, immediate and
continuing right to collect and receive all Rents now or hereafter, including
during any period of redemption, accruing with respect to the Property. At the
request of the Mortgagee or such Receiver, the Mortgagor shall promptly execute,
acknowledge, deliver, record, register and file any additional general
assignment of the Leases or specific assignment of any Lease which the Mortgagee
or such Receiver may require from time to time (all in form and substance
satisfactory to the Mortgagee or such Receiver) to effectuate, complete,
perfect, continue or preserve the assignments of the Leases and the Rents under
Granting Clauses VI and VII.

          (b) So long as an Event of Default is not continuing, the Mortgagor
shall have a license to collect and receive all Rents (but not prior to thirty
(30) days before the due date thereof) and apply the same subject to the
provisions of the Financing Documents, such license to be terminable as provided
in Section 5.07(c).

          (c) If an Event of Default has occurred and is continuing, the
Mortgagee or a Receiver appointed pursuant to Section 5.02(a)(v) (whichever is
the Person exercising the rights under this Section) shall have the right to
terminate the license granted under Section 5.07(b) by notice to the


                                       27
<PAGE>

Mortgagor and to exercise the rights and remedies provided under Section
5.07(a), under Sections 5.02(a)(vi) and (vi) or under applicable law. If an
Event of Default is continuing, upon demand by the Person exercising the rights
under this Section, the Mortgagor shall promptly pay to such Person all Security
Deposits under the Leases and all Rents allocable to any period after such
demand. Subject to Sections 5.02(a)(vi) and (vi) and any applicable requirement
of law, any Rents received hereunder by such Person exercising the rights under
this Section shall be promptly paid to the Mortgagee, and any Rents received
hereunder by the Mortgagee shall be deposited in the applicable Collateral
Account, to be held, applied and disbursed as provided in the Security
Agreement, PROVIDED that, subject to Sections 5.02(a)(vi) and (vi) and any
mandatory requirement of applicable law, any Security Deposits actually received
by such Person shall be promptly paid to the Mortgagee, and any Security
Deposits actually received by the Mortgagee shall be held, applied and disbursed
as provided in the applicable Leases and applicable law. If after the occurrence
of an Event of Default all Events of Default shall have been fully cured or
waived as provided in the Credit Agreement, the license granted in Section
5.07(b) shall automatically be reinstated.

          (d) Nothing herein shall be construed to be an assumption by the
Person exercising the rights under this Section, or otherwise to make such
Person liable for the performance, of any of the obligations of the Mortgagor
under the Leases, PROVIDED that such Person shall be accountable as provided in
Section 5.07(c) for any Rents or Security Deposits actually received by such
Person.

         SECTION 5.8. DEALING WITH THE MORTGAGED PROPERTY. Subject to Section
7.01, the Mortgagee shall have the right to release any portion of the Mortgaged
Property, or grant or consent to the granting of any Lien affecting any portion
of the Mortgaged Property at the request of the Mortgagor, in each case, for
such consideration as the Mortgagee may require without, as to the remainder of
the Mortgaged Property, in any way impairing or affecting the Lien or priority
of this Mortgage, improving the position of any subordinate lienholder with
respect thereto or impairing or affecting the rights of any maker, guarantor,
endorser, co-maker or other obligor of the Secured Obligations, except to the
extent that the Secured Obligations shall have been reduced by any actual
monetary consideration received for such release and applied to the Secured
Obligations, and may accept by assignment, pledge or otherwise any other
property in place thereof as the Mortgagee may require without being accountable
therefor to any other lienholder.

         SECTION 5.9. RIGHT OF ENTRY. The Mortgagee and its representatives
shall have the right (but not the obligation) (i) without prior notice if an
Event of Default is continuing, or (ii) with simultaneous notice, if any payment
or performance is immediately required in the reasonable opinion of the
Mortgagee to preserve the Mortgagee's right under this Mortgage or with respect
to the Mortgaged Property or (iii) after reasonable notice in all other cases,
to enter upon the Property at all reasonable times and with reasonable frequency
to inspect the Mortgaged Property or, subject to the provisions hereof, to
exercise any right, power or remedy of the Mortgagee hereunder, PROVIDED that
any Person so entering the Property shall not unreasonably interfere with the
ordinary conduct of the Mortgagor's business, and PROVIDED FURTHER that no such
entry on the Property for the purpose of performing obligations under Section
5.10 or for any other purpose shall be construed to be (x) possession of the
Property by such Person or to constitute such Person as a beneficiary, trustee
or mortgagee in possession, unless such Person exercises its right to take
possession of the Property under Section 5.02(a)(vi), or (y) a cure of any
Default or waiver of any


                                       28
<PAGE>

Default or Secured Obligation. The expense of any inspection pursuant to clause
(iii) above shall be borne by the Mortgagee unless an Event of Default shall
have occurred and be continuing at the time of such inspection, in which case
the Mortgagor shall reimburse the Mortgagee for such expense.

         SECTION 5.10. RIGHT TO PERFORM OBLIGATIONS. If the Mortgagor fails to
pay or perform any obligation of the Mortgagor hereunder, the Mortgagee and its
representatives shall have the right (but not the obligation) to pay or perform
such obligation of the Mortgagor (i) without notice, if an Event of Default is
continuing, (ii) with simultaneous notice, if such payment or performance is
immediately required in the reasonable opinion of the Mortgagee to preserve the
Mortgagee's rights under this Mortgage or with respect to the Mortgaged Property
or (iii) otherwise, after notice given reasonably in advance to allow the
Mortgagor an opportunity to pay or perform the same, PROVIDED that the Mortgagor
is not contesting such payment or performance as provided in Section 2.06, and
PROVIDED FURTHER no such payment or performance by the Mortgagee or its
representatives shall be construed to be a cure of any Default or waiver of any
Default or Secured Obligation. The Mortgagor shall reimburse the Mortgagee on
demand for its reasonable costs in connection with paying or performing any such
obligation of the Mortgagor (including reasonable attorneys' fees and expenses),
together with interest from the date of demand for each day until paid at the
Post-Default Rate for Base Rate Loans.

                      SECURITY AGREEMENT AND FIXTURE FILING

         SECTION 6.1. SECURITY AGREEMENT. To the extent that the Mortgaged
Property constitutes or includes tangible or intangible personal property,
including goods or items of personal property which are or are to become
fixtures under applicable law, the Mortgagor hereby grants a security interest
therein and this Mortgage shall also be construed as a pledge and a security
agreement under the UCC; and, upon the occurrence and continuance of an Event of
Default, the Mortgagee shall be entitled to exercise with respect to such
tangible or intangible personal property all remedies available under the UCC
and all other remedies available under applicable law. Without limiting the
foregoing, upon the occurrence and continuation of an Event of Default, any
personal property may, at the Mortgagee's option and, except as otherwise
required by applicable law, without the giving of notice, (i) be sold hereunder,
(ii) be sold pursuant to the UCC or (iii) be dealt with by the Mortgagee in any
other manner permitted under applicable law. The Mortgagee may require the
Mortgagor to assemble the personal property and make it available to the
Mortgagee at a place to be designated by the Mortgagee. At any time and from
time to time upon the occurrence and continuance of an Event of Default, the
Mortgagee shall be the attorney-in-fact of the Mortgagor with respect to any and
all matters pertaining to the personal property with full power and authority to
give instructions with respect to the collection and remittance of payments, to
endorse checks, to enforce the rights and remedies of the Mortgagor and to
execute on behalf of the Mortgagor and in Mortgagor's name any instruction,
agreement or other writing required therefor. The Mortgagor acknowledges and
agrees that a disposition of the personal property in accordance with the
Mortgagee's rights and remedies in respect to the other Mortgaged Property as


                                       29
<PAGE>

heretofore provided is a commercially reasonable disposition thereof.
Notwithstanding the foregoing, to the extent that the Mortgaged Property
includes personal property (that is not a fixture or otherwise become real
property under applicable law) covered by the Security Agreement, the provisions
of the Security Agreement shall govern with respect to such personal property.

         SECTION 6.2. FIXTURE FILING. To the extent that the Mortgaged Property

the Property is located shall also operate from the time of filing as a fixture

         release any Mortgaged Property from the Lien of this Mortgage pursuant
         to Section 2.17 of the Credit Agreement, the Lien of this Mortgage in
         such Mortgaged Property shall terminate and all rights to each item of

         into in order to transfer to the Administrative Agent a portion of cash
         proceeds sufficient to make the prepayment of Loans, if any, as
         required by Section 2.17(b) of the Credit Agreement and to the extent
         such Mortgaged Property constitutes Additional Collateral (as defined
         in the Security Agreement), the Collateral Agent will establish an
         account with the Administrative Agent, in the name and under the
         exclusive control of the Collateral Agent, into which all cash proceeds
         of the sale shall be deposited; or

Property, the Mortgagee shall, at the expense of the Mortgagor, execute,
acknowledge and deliver to the Mortgagor such documents, without warranty or
recourse, as the Mortgagor shall reasonably request to evidence the release of
Mortgaged Property or termination of this Mortgage, as the case may be.
