            NOW, THEREFORE, in consideration of the promises and the mutual
agreements herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto,
intending to be legally bound, agree as follows:

                                    ARTICLE I
                                     WAIVER

            SECTION 1.1. Waiver. (a) Subject to the conditions and upon the
terms set forth in this Waiver and in reliance on the representations and
warranties of the Borrowers set forth in this Waiver, the Lenders hereby waive
compliance by Borrowers with the requirements of subsection 9.1(a) of the Credit
Agreement, only insofar as it requires the Consolidated Revenue

                                       1
<PAGE>
of SMC for the period beginning on April 1, 2002 and ending on September 30,

            (b) This Waiver shall be effective only through November 15, 2002,
after which date it shall terminate and be of no further force and effect
without any action by the Borrowers, the Lenders, or the Agent.

            (c) This Waiver is limited solely to the matters set forth in this
Section 1.1, as at the date stated herein, and does not constitute a waiver of
any other Default or Event of Default or compliance with any other term or
condition of the Loan Documents.

                                   ARTICLE II
                              CONDITIONS PRECEDENT

            The effectiveness of this Waiver shall be subject to the
satisfaction of each of the following conditions precedent:

            SECTION 2.1. Waiver. Each of the Agent and the Required Lenders
shall have executed this Waiver and the Borrowers shall have delivered to the
Agent duly executed counterparts of this Waiver.

            SECTION 2.2. Approval of the Bankruptcy Court. The Borrowers shall
have delivered to the Agent a true and correct copy of the final order(s)
entered by the Bankruptcy Court approving the payment of the Waiver Fee and the
Adequate Protection Payment (each as defined below) by the Borrowers to the
Agent on behalf of the Lenders.

            SECTION 2.3. Waiver Fee. The Borrowers shall have paid to the Agent
a waiver fee (the "Waiver Fee") equal to 0.125% applied to sum of the aggregate
(a) outstanding Revolving Credit Loans, plus (b) Letters of Credit Outstanding,
plus (c) Unused Revolving Credit Commitments of each Lender. Such fee (i) shall
be received by the Agent ratably for account of, and shall be remitted by the
Agent, to the Lenders and (ii) shall be fully earned and nonrefundable when
paid.

            SECTION 2.4. Adequate Protection Payment. The Borrowers shall have
paid to the administrative agent (the "Prepetition Agent") under the Existing
Credit Agreement an adequate protection payment (the "Adequate Protection
Payment") in the amount of $2,500,000. Such payment (i) shall be received by the
Prepetition Agent and applied to repay the Deemed DIP Loans ratably for account
of the lenders under the Existing Credit Agreement and (ii) shall be fully
earned and nonrefundable when paid. The Adequate Protection Payment shall be
deemed to have been used to repay Prepetition Indebtedness for purposes of the
proviso to the first sentence of Section 5.1(b) of the Credit Agreement and
shall therefore apply dollar-for-dollar against the $30,000,000 basket specified
therein.

            SECTION 2.5. Representations and Warranties. Each Borrower shall
have confirmed to the Agent, by the signature of a Responsible Officer of such
Borrower below, that on and as of the date of this Waiver:

                                       2
<PAGE>
            (a) each of the representations and warranties made by the Borrowers
or their Subsidiaries in or pursuant to the Loan Documents is true and correct
in all material respects (except that any such representation or warranty that
is expressly stated as being made only as of a specified earlier date shall be
true and correct in all material respects as of such earlier date);

            (b) other than the Event of Default that is the subject of this
Waiver, no Default or Event of Default has occurred and is continuing; and

            (c) none of the Bankruptcy Cases has been dismissed or converted to
Chapter 7 of the Bankruptcy Code, no Person has filed an application for an
order dismissing any Borrower's Bankruptcy Case or converting any Borrower's
Bankruptcy Case to a case under Chapter 7 of the Bankruptcy Code, and no trustee
under Chapter 7 or Chapter 11 of the Bankruptcy Code or responsible officer or
examiner with powers beyond the duty to investigate and report, as set forth in
Sections 1106(a)(3) and (4) of the Bankruptcy Code has been appointed in any of
the Bankruptcy Cases. No application has been filed by any Borrower for the
approval of any other superpriority administrative claim in any Bankruptcy Case
which is pari passu with or senior to the claims of the Agent and/or any Lender
against the Borrowers (and, other than the Carve-Out, no such claim or lien has
arisen) and the Final Order is in full force and effect and has not been stayed,
modified, amended, reversed, rescinded or vacated.

                                   ARTICLE III
                                  MISCELLANEOUS

            SECTION 3.1. Execution of this Waiver. This Waiver is executed and
shall be construed as the Fourth Waiver to the Postpetition Credit Agreement,
and, as provided in the Credit Agreement, this Waiver forms a part thereof and
is a Loan Document.

            SECTION 3.2. Waiver. This Waiver shall not constitute an amendment
or waiver of or consent to any provision of the Credit Agreement or any other
Loan Document not expressly referred to herein and shall not be construed as an
amendment, waiver or consent to any action on the part of the Borrowers that
would require an amendment, waiver or consent of the Agent or the Lenders except
as expressly stated herein. The execution, delivery and performance by the
parties hereto of this Waiver shall not constitute a waiver, forbearance or
other indulgence with respect to any Default or Event of Default now existing or
hereafter arising, except as expressly set forth herein. Except as specifically
modified pursuant to the terms of this Waiver, the terms and conditions of the
Credit Agreement and the other Loan Documents remain in full force and effect.
Nothing herein shall limit in any way the rights and remedies of the Agent and
the Lenders under the Credit Agreement and the other Loan Documents.

            SECTION 3.3. Counterparts; Integration; Effectiveness. This Waiver
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Waiver constitutes the
entire contract among the parties hereto relating to the subject matter hereof
and supersedes any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. Upon the effectiveness of this
Waiver as set forth in Article II hereof, this Waiver shall be binding upon and
inure to the benefit of the parties hereto and, subject to and in accordance
with SECTION 12.6 of the Credit Agreement, their respective

                                       3
<PAGE>
successors and assigns. Delivery of an executed counterpart of a signature page
of this Waiver by facsimile shall be as effective as delivery of a manually
executed counterpart of this Waiver.

            SECTION 3.4. Ratification. Subject to the waiver provided hereby,
the Loan Documents shall continue to be in full force and effect and are hereby
in all respects ratified and confirmed.

                  SECTION 3.5. Severability. Any provision of this Waiver held
to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

            SECTION 3.6. Expenses. The Borrowers agree to pay or reimburse the
Agent for all of its reasonable out-of-pocket costs and expenses incurred in
connection with this Waiver, any other documents prepared in connection herewith
and the transactions contemplated hereby, including, without limitation, the
reasonable fees and disbursements of counsel to the Agent.

            SECTION 3.7. Governing Law. THIS WAIVER AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS WAIVER SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAW OF THE STATE OF NEW YORK
WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF THAT WOULD
DIRECT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION, ALL TO THE EXTENT NOT
PREEMPTED BY THE FEDERAL BANKRUPTCY LAWS OF THE UNITED STATES; PROVIDED, THAT
THE LENDERS AND AGENT SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

            SECTION 3.8. Headings. Article and Section headings used herein are
for convenience of reference only, are not part of this Waiver and shall not
affect the construction of, or be taken into consideration in interpreting, this
Waiver.

                             SECURED PROMISSORY NOTE

$6,000,000.00                                                     March 11, 2002

            FOR VALUE RECEIVED, the undersigned, AMERICOLD LOGISTICS, LLC, a
Delaware limited liability company (hereinafter referred to as "Borrower"),
hereby promises to pay to the order of VORNADO OPERATING L.P., a Delaware
limited partnership (hereinafter referred to as "Noteholder," which term shall
mean the holder at any particular time of this Note) the principal sum of SIX
MILLION and NO/100ths DOLLARS ($6,000,000.00), together with interest as
hereinafter provided.

            From the date hereinabove set forth, until this Note is paid in
full, interest shall be charged on the principal balance of this Note
outstanding from time to time at an annual rate (the "Interest Rate") equal to
twelve percent (12%). The entire unpaid principal balance of this Note and all
accrued and unpaid interest thereon shall be due and payable on December 31,
2004 (the "Maturity Date"), unless this Note shall be accelerated sooner
pursuant to any provision hereof. Interest will be due and payable in arrears on
the seventeenth day of each calendar month beginning on November 17, 2002,
through and including the Maturity Date, provided that so long as no Event of
Default shall have occurred and be continuing, unless Borrower shall make such
payment of interest, the amount thereof shall be added to the principal amount
of this Note and shall thereafter accrue interest at the Interest Rate.

            All payments received hereunder shall be applied first to accrued
interest and the balance, if any, to principal. The principal of and interest on
this Note shall be payable in immediately available funds in lawful money of the
United States. Any payment by other than immediately available funds which
Noteholder, at its option, elects to accept shall be subject to collection, and
interest shall continue to accrue thereon until the funds by which payment is
made are available to Noteholder for its use. All payments hereunder shall be
payable to the order of Noteholder at 210 Route 4, Paramus, New Jersey 07652, or
at such place and to such person as shall be designated in writing from time to
time by Noteholder.

            Borrower hereby agrees to pay Noteholder any and all fees and costs,
including, without limitation, Noteholder's reasonable legal fees, incurred by
Noteholder in connection with the loan evidenced hereby and the preparation,
negotiation, recordation, filing and/or enforcement of this Note and the Loan
Documents (as defined below).

            Borrower reserves the privilege of prepaying without premium or
penalty, all or any portion of the principal balance of this Note, together with
accrued interest thereon to the date of payment.
<PAGE>
            If any payment required to be made under this Note is not paid when
due and payable hereunder, whether at maturity or by acceleration, (i) interest
shall be payable on the principal portion of such payment and, to the extent
permitted by law, on all accrued but unpaid interest and other amounts
outstanding hereunder, at the Interest Rate, and (ii) Borrower promises to pay
all costs of collection, including reasonable attorneys' fees, incurred by
Noteholder, whether or not suit is filed hereon. Such costs of collection shall
include, but not be limited to, all costs and expenses, including reasonable
attorneys' fees, incurred in connection with the protection of or realization
upon the collateral securing this Note.

            At the option of Noteholder, this Note shall become immediately due
and payable if any of the following shall occur: (i) if Borrower fails to make
any payment hereunder when such payment is due and payable; (ii) if Borrower
fails to observe or perform any covenant to be observed or performed by Borrower
under this Note; (iii) a receiver, liquidator or trustee shall be appointed for
Borrower or Borrower shall be adjudicated a bankrupt or insolvent, or if any
petition for bankruptcy, reorganization or arrangement pursuant to federal
bankruptcy law, or any similar federal or state law, shall be filed by or
against, consented to, or acquiesced in by, Borrower or if any proceeding for
the dissolution or liquidation of Borrower shall be instituted; provided,
however, if such appointment, adjudication, petition or proceeding was
involuntary and not consented to by Borrower upon the same not being discharged,
stayed or dismissed within ninety (90) days; or (iv) if there shall exist any
"Event of Default", as such term is defined in that certain Security Agreement
(the "Security Agreement"), dated of even date herewith, between the Borrower
and Noteholder.

            The failure of Noteholder to exercise its option to accelerate this
Note as provided above, or to exercise any other option or remedy granted to it
under this Note, the Security Agreement or any other document, instrument or
agreement now or hereafter evidencing or securing the indebtedness evidenced by
this Note as amended from time to time (collectively, the "Loan Documents"), in
any one or more instances, or the acceptance by Noteholder of partial payments
or partial performance, shall not constitute a waiver of any default by
Borrower, and all such options and remedies shall remain continuously in force.
Acceleration of maturity, once claimed hereunder by Noteholder, may at
Noteholder's option be rescinded by written acknowledgment to that effect, but
the tender and acceptance of partial payment or partial performance alone shall
not in any way affect or rescind such acceleration of maturity.

            Borrower agrees hereby to (i) waive and renounce any and all
homestead exemption rights and the benefits of all valuation and appraisement
privileges as against this debt or any renewal or extension hereof; and (ii)
waive presentment, demand, protest, notice of nonpayment, notice of dishonor,
and any and all lack of diligence or delays in the collection or enforcement
hereof.
<PAGE>
            In no event shall the amount of interest due or payable hereunder
exceed the maximum amount of interest allowed by applicable law or otherwise
violate applicable law, and in the event any payment is made which exceeds such
maximum lawful amount, then the amount of such excess sum shall be credited as a
payment of principal. It is the express intent hereof that Borrower shall not
pay and Noteholder shall not receive, directly or indirectly, interest in excess
