                  (b)      Deferral Option. During the term of the Note, the
Borrower may elect to defer the payment of all or a portion of the interest due
and payable on a Payment Date (other than the Maturity Date) and instead may, at

repay to the Purchaser on February 18, 2009, the unpaid principal balance of,

whether by reason of acceleration of the maturity of the amounts due hereunder
or otherwise, shall interest and fees contracted for, charged, received, paid or
agreed to be paid to the Purchaser exceed the maximum amount permissible under
such applicable law. If, from any circumstance whatsoever, interest and fees
would otherwise be payable to the Purchaser in excess of the maximum amount
permissible under applicable law, the interest and fees shall be reduced to the
maximum amount permitted under applicable law. If from any circumstance, the
Purchaser shall have received anything of value deemed interest by applicable
law in excess of the maximum lawful amount, an amount equal to any excess
interest shall be applied to the reduction of the principal amount of the Note,
in such manner as may be determined by the Purchaser, and not to the payment of
fees or interest, or if such excessive interest exceeds the unpaid balance of
the principal amount of the Note, such excess shall be refunded to the Borrower;
provided, however, that in such event the Conversion Price (as defined in the
Note) of the Note shall be adjusted to preserve the economic effects of the
transactions contemplated by this Agreement.

Agreement, the Note, Warrants and the other Transaction Documents have been duly
authorized by all necessary corporate action on the part of the Borrower and
each Guarantor, as applicable, except for stockholder approval of the
transactions contemplated by this Agreement as required under Section 713 of the
Listing Standards, Policies and Requirements of the American Stock Exchange.
This Agreement, the Note, the Warrants and the other Transaction Documents have
been duly executed and delivered by the Borrower and each Guarantor, as
applicable, and constitute legal, valid and binding obligations of the Borrower,
and each Guarantor, as applicable, enforceable against it in accordance with
their respective terms, except (i) that such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance and transfer and similar laws of general application relating to or
affecting the rights and remedies of creditors, and (ii) that acceleration of
the Note may affect the collectibility of that portion of the stated principal
amount thereof which might be determined to constitute unearned interest
thereon.

                  (c)      No Other Indebtedness. Neither the Borrower nor any
Guarantor has any outstanding Indebtedness to any person or entity other than
the Bonds, the Senior Debt, the Indebtedness contemplated by this Agreement and
the Indebtedness set forth on Schedule 5.1(c) hereto ("Permitted Indebtedness").

environmental conditions; and (iii) other activities incidental to the business
(the "Business").

the Purchaser complete and correct copies of (i) its annual report to
stockholders for the fiscal year ended February 22, 2002 (the "Annual Report")

Securities and Exchange Commission (the "Form 10-K"), and (ii) its quarterly
report on Form 10-Q for the Fiscal Quarter ended November 22, 2002 as filed with
the Securities and Exchange Commission (the "Form 10-Q"). The Annual Report and
the Form 10-K correctly describe, in all material respects, as of their
respective dates, the business then conducted and proposed to be conducted by
the Borrower. There are included in the Form 10-K financial statements of the
Borrower for the fiscal year ended February 22, 2002, accompanied by the opinion
thereon of Grant Thornton LLP, independent public accountants, and in the Form
10-Q financial statements of the Borrower for the Fiscal Quarter ended November
22, 2002. All financial statements included in the foregoing materials delivered
to the Purchaser (except as otherwise specified therein) have been prepared in
accordance with GAAP applied on a consistent basis throughout the periods
specified and present fairly the financial position of the Borrower and its
Subsidiaries as of the respective dates specified and the results of their
operations and cash flows for the respective periods specified (with normal
year-end adjustments, which in the aggregate would not have a Material Adverse
Effect on the Company).

as of the Closing Date, the Borrower will not have outstanding securities
convertible into or exchangeable for any shares of its capital stock, nor will
it have outstanding any rights to subscribe for or to purchase, or any options
for the purchase of, or any agreements providing for the issuance (contingent or
otherwise) of, or any calls, commitments or claims of any character relating to,
any shares of its capital stock or any securities convertible into or
exchangeable for any shares of its capital stock.

                  (g)      No Breach. Except as specifically provided by the
Transaction Documents, the execution and delivery by the Borrower and each
Guarantor of the Transaction Documents, as applicable, and the consummation of
the Transactions do not and will not (i) conflict with or result in a breach of
the terms, conditions or provisions of, (ii) constitute a default under, (iii)

Borrower or any Guarantor is a party or to which they or their assets are
subject.

                  (h)      Governmental Approvals. Except as specifically
provided by the Transaction Documents, no registration with or consent or
approval of, or other action by, any Governmental Authority or any other Person
is or will be required in connection with the consummation of the Transactions
by the Borrower or Guarantors and the performance of their obligations
thereunder.

officers or the businesses, assets or rights of the Borrower or any Guarantor.

                  (k)      Compliance with Laws. Neither the Borrower nor any
Guarantor is in violation of any applicable Law, the affect of which violation

compliance with any judgment, order, writ, injunction or decree of any
Governmental Authority or to maintain any material permits, approvals or
licenses granted by any Governmental Authority in full force and effect.

                                       20


                           (i)      The Borrower will apply any proceeds of the
         sale of the Note and Warrants, together with the proceeds of borrowings
         under the Senior Credit Agreement, simultaneously with the Closing, (a)

         the meaning of Regulations T, U or X issued by the Board of Governors
         of the Federal Reserve System), and no proceeds of the sale of the Note
         and Warrants will be used to purchase or carry any margin stock or
         margin security or to extend credit to others for the purpose of
         purchasing or carrying any margin stock or margin security.

                  (n)      Taxes. Each of the Borrower and each Guarantor has
filed or caused to be filed all tax returns which are required to be filed and
have paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other taxes, fees or
other charges imposed on it or any of its property by any Governmental Authority

no tax Lien has been filed against the Borrower or any Guarantor, and, to the
knowledge of the Borrower, no claim is being asserted, with respect to any such

                  (o)      ERISA; Labor and Employment.

                           (i)      The Borrower is and each of its Plans are in
         compliance in all material respects with those provisions of ERISA, the
         Code, the Age Discrimination in Employment Act, and the regulations and
         published interpretations thereunder which are applicable to the
         Borrower or any such Plan. As of the date hereof, no Reportable Event
         has occurred with respect to any Plan as to which the Borrower is or
         was required to file a report with the PBGC. No Plan has any material
         amount of unfunded benefit liabilities (within the meaning of Section
         4001(a)(18) of ERISA) or any accumulated funding deficiency (within the
         meaning of Section 302(a)(2) of ERISA), whether or not waived, and the
         Borrower has not incurred nor reasonably expects to incur any material
         withdrawal liability under Subtitle E of Title IV of ERISA to a
         Multiemployer Plan. The Borrower is in compliance in all material
         respects with all labor and employment laws, rules, regulations and
         requirements of all applicable domestic and foreign jurisdictions.
         There are no pending or threatened labor disputes, work stoppages or
         strikes.


                                       21

         collective bargaining agreement, and there are no strikes, work
         stoppages, material grievances, disputes or controversies with any
         union or any other organization of the Borrower's employees, or threats
         of strikes, work stoppages or any asserted pending demands for
         collective bargaining by any union or organization, except to the
         extent that such strikes, work stoppages, material grievances, disputes
         or controversies could not reasonably be expected to have a Material
         Adverse Effect. The Borrower has not, within the two-year period
         preceding the Closing Date, taken any action which would have
         constituted or resulted in a "plant closing" or "mass layoff" within
         the meaning of the Federal Worker Adjustment and Retraining
         Notification Act of 1988 or any similar Law. The procedures by which
         each of the Borrower has hired or will hire its employees comply and
         will comply in all material respects with each collective bargaining
         agreement to which the Borrower is a party and any applicable Law. The
         Borrower is in compliance with the Fair Labor Standards Act, as
         amended, and has paid all minimum and overtime wages required by law to
         be paid to its respective employees, except for violations which could
         not have a Material Adverse Effect.

                  (p)      Investment Company Act; Public Utility Holding
Company Act. The Borrower is not (i) an "investment company" or "controlled" by
an investment company within the meaning of the Investment Company Act of 1940,
as amended, or (ii) a "holding company" or a "subsidiary company" of a "holding
company" or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

                  (q)      Condition of and Title to Properties. The real
property owned or leased by the Borrower and any Guarantor in the United States
as of the Closing Date is described on Schedule 5.1(q) hereto. Each of the
Borrower and each Guarantor has good title to or valid leasehold interest in all
properties, assets and other rights which it purports to own or lease or which
are reflected as owned or leased on its books and records (the "Properties and
Facilities"), free and clear of all Liens and encumbrances except Permitted
Liens, and subject to the terms and conditions of the applicable leases. Except
as described on Schedule 5.1(q), all leases of property are in full force and
effect. No consent under any lease is required in connection with the
consummation of the transactions contemplated hereby. Except for financing
statements evidencing Permitted Liens, no effective financing statement under
the Uniform Commercial Code is in effect in any jurisdiction and no other filing
which names the Borrower or any Guarantor as debtor or which covers or purports
to cover any of the assets of the Borrower or any Guarantor is currently
effective and on file in any state or other jurisdiction, and neither the
Borrower nor any Guarantor has signed any such financing statement or filing or
any security agreement authorizing any secured party thereunder to file any such
financing statement or filing. All of the assets and properties of the Borrower
and each Guarantor that are necessary for the operation of their respective
businesses are in good working condition and are able to serve the functions for
which they are currently being used, except for ordinary wear and tear.


                                       22


                  (r)      Proprietary Rights. Each of the Borrower and each
Guarantor owns, or is licensed to use its Proprietary Rights necessary for the
conduct of its business as currently conducted. Except as set forth on Schedule
5.1(r), no claim has been asserted and is pending by any Person challenging or
questioning the use of any such Proprietary Rights, nor does the Borrower know
of any valid basis for any such claim. The use of such Proprietary Rights by the
Borrower and each Guarantor does not infringe the rights of any Person, except
for such claims and infringements that, in the aggregate, do not have a Material
Adverse Effect. To the best knowledge of the Borrower, except as set forth on
Schedule 5.1(r), no slogan or other advertising, device, product, process,
method, substance, part or component or other material now employed, or now
contemplated to be employed, by any of the Borrower and each Guarantor infringes
upon or conflicts with any rights owned by any other Person, and no claim or
litigation regarding any of the foregoing is pending or, to the knowledge of the
Borrower, threatened. No patent, invention, device, application, and no statute,
law, rule, regulation, standard or code involving the Borrower's or any
Guarantor's Proprietary Rights is pending or, to the knowledge of the Borrower,
proposed, except where the consequences in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

                  (s)      Solvency. After giving effect to the Transactions,
(i) the fair value of the assets of the Borrower and each Guarantor, at a fair
valuation, will exceed its debts and liabilities, subordinated, contingent or
otherwise, (ii) the present fair saleable value of the property of the Borrower
and each Guarantor will be greater than the amount that will be required to pay
the probable liability of its debts and other liabilities, subordinated,
contingent or otherwise, as such debts and other liabilities become absolute and
matured, (iii) the Borrower and each Guarantor will be able to pay their
respective debts and liabilities, subordinated, contingent or otherwise, as such
debts and liabilities become absolute and matured, and (iv) the Borrower will
not have unreasonably small capital with which to conduct the Business.

                  (t)      Subsidiaries. As of the Closing Date, the Borrower
has no Subsidiaries except for those set forth on Schedule 5.1(t), each of which
was duly formed and is existing under the law of the jurisdiction set forth
opposite their names. All of the issued and outstanding shares of capital stock
of the Subsidiaries are duly and validly authorized and issued and fully paid
and nonassessable and are owned by the Borrower, (except for directors'
qualifying shares). There are no options, warrants or other rights outstanding
to purchase any capital stock of any of the Subsidiaries, nor are any securities
of any of the Subsidiaries convertible into or exchangeable for capital stock of
the Subsidiaries except as described on Schedule 5.1(t).

                  (u)      Broker's or Finder's Commissions. Except as set forth
on Schedule 5.1(u), no broker's or finder's or placement fee or commission will
be payable to any broker or agent engaged by the Borrower or any of its
officers, directors or agents with respect to the issuance and sale of the Note,
the Warrants or the Transactions. The Borrower agrees to indemnify the Purchaser
and hold Purchaser harmless from and against any claim, demand or liability for
broker's or finder's or placement fees or similar commissions, alleged to have
been incurred in connection with such transactions, other than any broker's or
finder's fees payable to Persons engaged by the Purchaser.

                  (v)      Absence of Undisclosed Liabilities. Except as set
forth on Schedule 5.1(v), the Borrower has no liabilities or obligations, either
accrued, absolute, contingent or otherwise, except:

                           (i)      those liabilities or obligations set forth
         on the Financial Statements and not heretofore paid or discharged,


                                       23


                           (ii)     liabilities arising in the ordinary course
         of business under any agreement, contract, commitment, lease or plan
         specifically disclosed on the schedules or not required to be disclosed
         because of the term or amount involved or otherwise, and

                           (iii)    those liabilities or obligations incurred,
         consistently with past business practice, in or as a result of the
         normal and ordinary course of business.

                  (w)      Federal Regulations. No part of the proceeds of the
Loan will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U or for any
purpose which violates the provisions of Regulation U or any other Regulations
of the Board of Governors of the Federal Reserve System. If requested by the
Purchaser, the Borrower will furnish to the Purchaser a statement to the
foregoing effect in conformity with the requirements of FR Form U-l referred to
in said Regulation U. No part of the proceeds of the Loan hereunder will be used

and material hereafter furnished by or on behalf of the Borrower will be, true
and accurate in all material respects on the date as of which such information
is furnished and not incomplete or misleading by omitting to state any fact
necessary to make such information not misleading at such time in light of the
circumstances under which such information was provided.

                  (y)      Security Interests. At all times after execution and
delivery of the Security Documents by the party or parties thereto and
completion of the filings and recordings listed on Schedule 5.1(y), the security
interests created for the benefit of the Purchaser pursuant to the Security
Documents will constitute valid, perfected security interests in the collateral
subject thereto, subject to no other Liens whatsoever, except Permitted Liens.

                  (z)      Insurance. The Borrower currently maintains insurance
which meets or exceeds the requirements of Section 7.1(c) and the applicable
insurance requirements set forth in the other Transaction Documents. Schedule
5.1(z) hereto lists, as of the Closing Date, all insurance policies and other
bonds to which the Borrower is a party, all of which are valid and in full force
and effect. No written notice has been given or claim made and the Borrower has
no knowledge that any grounds exist to cancel or avoid any of such policies or
bonds or to reduce the coverage provided thereby or any replacements thereof.
Such policies and bonds or any replacements thereof provide adequate coverage
from reputable and financially sound insurers in amounts sufficient to insure
the assets and risks of the Borrower in accordance with prudent business
practice in the industry of the Borrower.

         approvals of each Governmental Authority (the "Governmental Approvals")
         necessary for the operations of its business and is not in material
         violation thereof. All such Governmental Approvals are in full force
         and effect, and no event has occurred that permits, or after notice or
         lapse of time could permit, the revocation, termination or material and
         adverse modification of any such Governmental Approval.


                                       24


                           (ii)     Except as set forth on Schedule 5.1(aa),

         Authority, or of any other proceedings of or before any Governmental

         Adverse Effect.

any of its Subsidiaries, nor any director, officer, agent, employee or other

                  (ee)     No Defaults. Except as set forth on Schedule 5.1(ee),
neither the Borrower nor any Guarantor is in default under or with respect to
any of its Contractual Obligations in any respect which could reasonably be
expected to have a Material Adverse Effect. No Default or Event of Default has
occurred and is continuing.

All of the foregoing representations and warranties shall survive the execution
and delivery of the Note and the making by the Purchaser of the Loan hereunder
and shall continue in full force and effect so long as any indebtedness or
obligation of the Borrower to the Purchaser hereunder or otherwise is
outstanding or unperformed or this Agreement remains in effect.

                                   ARTICLE VI

                             RESTRICTED SECURITIES

         6.1      Restricted Securities. The Purchaser acknowledges that the
Securities have not been registered under the Securities Act and may be resold
only if registered pursuant to the provisions of the Securities Act or if an
exemption from registration is available, and, except as provided in the
Registration Rights Agreement, that the Borrower is not required to register any
of the Securities.


                                       25


         6.2      Legends; Purchaser's Representations. The Purchaser hereby
represents and warrants to the Borrower that it is an "accredited investor"
within the meaning of Rule 501(a) under the Securities Act and is acquiring the
Securities for investment for the Purchaser's own account, with no present
intention of dividing its participation with others (except for a potential
transfer or transfers of the Securities to an affiliate or affiliates of the
Purchaser) or reselling or otherwise distributing the same in violation of the
Securities Act or any applicable state securities laws. The Borrower may place
an appropriate legend on the Securities owned by the Purchaser concerning the
restrictions set forth in this Article 6. Upon the assignment or transfer by the
Purchaser or any of its successors or assignees of all or any part of the
Securities, the term "Purchaser" as used herein shall thereafter mean, to the
extent thereof, the then holder or holders of such Securities, or portion
thereof.

         6.3      Prohibition on Short Sales. The Purchaser will not engage in
any short sale of any shares of Common Stock or have in effect a short position
with respect thereto (whether such short sale or position is against the box and
regardless of when such position was entered into).

         6.4      Transfer of Notes. Subject to Section 6.2 hereof, a holder of
a Note may transfer such Note to a new holder, or may exchange such Note for
Notes of different denominations (but in no event of denominations of less than
$500,000 or increments of $100,000 in excess thereof in original principal
amount), by surrendering such Note to the Borrower duly endorsed for transfer or
accompanied by a duly executed instrument of transfer naming the new holder (or
the current holder if submitted for exchange only), together with written
instructions for the issuance of one or more new Notes specifying the respective
principal amounts of each new Note and the name of each new holder and each
address therefor. The Borrower shall simultaneously deliver to such holder or
its designee such new Notes, shall mark the surrendered Notes as canceled. The
Borrower shall not be required to recognize any subsequent holder of a Note
unless and until the Borrower have received reasonable assurance that all
applicable transfer taxes have been paid. Notwithstanding the foregoing, a
holder of a Note may not transfer such Note or shares of Common Stock issuable
upon conversion of such Note to a competitor of the Borrower or any Subsidiary
or affiliate of the Borrower.

         6.5      Replacement of Lost Securities. Upon receipt of evidence
reasonably satisfactory to the Borrower of the mutilation, destruction, loss or
theft of any Securities and the ownership thereof, the Borrower shall, upon the
written request of the holder of such Securities, execute and deliver in
replacement thereof new Securities in the same form, in the same original
principal amount and dated the same date as the Securities so mutilated,
destroyed, lost or stolen; and such Securities so mutilated, destroyed, lost or
stolen shall then be deemed no longer outstanding hereunder. If the Securities
being replaced have been mutilated, they shall be surrendered to the Borrower;
and if such replaced Securities have been destroyed, lost or stolen, such holder
thereof shall furnish the Borrower with a written indemnity, in form
satisfactory to the Borrower, to save it harmless in respect of such replaced
Security.

Transaction Documents and any and all contracts entered into by the Borrower
under policies issued by financially sound and reputable insurers in such
amounts as are customary with companies similarly situated and in the same or
similar business. The Borrower shall pay all insurance premiums payable by it
and shall deliver the policy or policies of such insurance (or certificates of

of the Borrower shall contain endorsements, in form and substance reasonably
satisfactory to the Purchaser, providing that the insurance shall not be
cancelable except upon thirty (30) days' prior written notice to Purchaser. The
Purchaser shall be shown as a loss payee and an additional named insured party
under all such insurance policies.

                  (d)      Obligations and Taxes. Pay and discharge promptly
when due all taxes, assessments and governmental charges or levies imposed upon
them or upon their income or profits or in respect of their properties before
the same shall become delinquent or in default, as well as all lawful claims for
labor, materials and supplies or otherwise, which, if unpaid, might give rise to
Liens or charges upon such properties or any part thereof; provided, however,
that neither the Borrower nor any Guarantor shall be required to pay and
discharge or to cause to be paid and discharged any such tax, assessment,
charge, levy or claim so long as the validity or amount thereof shall be
contested in good faith by appropriate proceedings and the Borrower or such
Guarantor shall have set aside on their books adequate reserves with respect
thereto.

         shall be limited to the property or assets covered by the Lien
         extended, renewed or replaced and that the obligations secured by any
         such extension, renewal or replacement Lien shall be in an amount not
         greater than the amount of the obligations secured by the Lien
         extended, renewed or replaced.

                  (c)      Contingent Obligations. Neither the Borrower nor any
Guarantor shall create, incur, assume or suffer to exist any Contingent
Obligation other than guarantees by the Borrower of Indebtedness of a
