(the "Projections"), true and complete copies of which have been delivered to

and attached as Exhibit 2 to the Disclosure Schedule, were prepared in good
faith on the assumptions stated therein, which assumptions were believed and
presently are believed to be fair and reasonable in light of conditions existing
at the time of delivery of such forecasts and those presently existing, and
represented, at the time of delivery, and continue to represent the Company's
reasonable estimate of its future financial performance, it being recognized
that such forecasts do not constitute a warranty as to the future performance

                                       -5-
<Page>

of the Company and that actual results may vary from forecasted results.

respect to Taxes which have accrued and are not yet due and payable, the same
have been properly reflected as a liability on the books and records of the
Company and adequate reserves therefor have been established. All such Tax
Returns have been properly prepared and are true, correct (and to the extent
such Tax Returns reflect judgments made by the Company or a Subsidiary, as the
case may be, such judgments were reasonable under the circumstances) and
complete in all material respects. Except as indicated in Item 2.7 of the
Disclosure Schedule, no extension for the filing of any Tax Return is currently
in effect. Except as indicated in Item 2.7 of the Disclosure Schedule, no Tax
Return or Tax Return liability of the Company or any Subsidiary has been audited

Company and in the Financial Statements. Except as indicated in Item 2.7 of the

the Company or Subsidiary is or may be subject to Taxes assessed by such
jurisdiction. Neither the Company nor any Subsidiary has been a member of an
Affiliated Group other than one consisting solely of two or more of the Company
and any of the Subsidiaries, or filed or been included in a combined,
consolidated or unitary income Tax Return, other than one filed by a group
consisting solely of two or more of the Company and any of the Subsidiaries.

Operating Agreements.

Notwithstanding the foregoing, Item 2.8 of the Disclosure Schedule and Items
2.10 and 2.19 of the Disclosure Schedule name or describe, and the term

                    exceeding $200,000;

            (iv)    each agreement or indenture relating to borrowed money or

                    debts or a guarantee by a Subsidiary of the Company's debts
                    or another Subsidiary's debts);

                    Subsidiary is lessor of, or permits any third party to hold
                    or operate, any property, real or personal, owned or

The Operating Agreements constitute all of the material contracts, agreements,
understandings and arrangements required for the operation of the business of
the Company and the Subsidiaries or which have a material effect thereon. True
and complete copies of all written Operating Agreements without schedules and
exhibits have previously been delivered or otherwise made available to the
Purchasers. Such schedules and exhibits contain no information which is material
to the provisions of the Operating Agreements.

            (b) Except as disclosed in Item 2.8 of the Disclosure Schedule,
neither the Company, any Subsidiary, nor, to the Company's knowledge, any other
Person or entity is in breach in any material respect of, or in default in any
material respect under, any Operating Agreement and no event or action has
occurred, is pending or is threatened, which, after the giving of notice,
passage of time or otherwise, would constitute or result in such a material
breach or material default by the Company or any Subsidiary or, to the knowledge
of the Company, any other Person or entity except for such breaches as would not
have a Material Adverse Effect. Neither the Company nor any Subsidiary has
received any notice of default under any Operating Agreement to which it is a
party, which default has not been cured to the satisfaction of, or duly waived
by, the party claiming such default on or before the date hereof. All of the
Operating Agreements on Item 2.8 of the Disclosure Schedule are in all material
respects, valid, binding and enforceable in accordance with their respective
terms. Neither the Company nor any Subsidiary has any present expectation or
intention of not fully performing its obligations under any Operating Agreement;
and, neither the Company nor any Subsidiary has knowledge of any anticipated
breach by the other parties to any Operating Agreement except for such breaches
or anticipated breaches as would not, singly or in the aggregate, have a
Material Adverse Effect.

            Except as set forth in Item 2.9 of the Disclosure Schedule, each of
the Company and the Subsidiaries has good and marketable title to all of its

disposed of in the ordinary course of business since December 31, 2000), free
and clear of all Liens or mortgages, except for (a) any Lien for current taxes
not yet due and payable, (b) restrictions, if any, on the disposition of
securities as may be imposed by federal or applicable state securities laws and
(c) failures of title or Liens as do not materially affect the value,
marketability, operation or the Company's and the Subsidiaries' use of such
assets or as would not, singly or in the aggregate, have a Material Adverse
Effect.

     2.10   REAL PROPERTY

            (a) Item 2.10(a) of the Disclosure Schedule sets forth a true and
complete list of all real property owned by the Company or any Subsidiary (the

located thereon, free and clear of all Liens, mortgages, encroachments,
restrictions on the use thereof, or other defects in title (collectively,

Adverse Effect.

                                       -8-
<Page>

            (b) Item 2.10(b)(i) of the Disclosure Schedule sets forth a true,
correct and complete list of all leases, subleases, licenses and other
agreements (collectively, the "Real Property Leases") under which the Company or
any Subsidiary uses or occupies, has the right to use or occupy, or leases the
right to use or occupy, now or in the future, any real property where the annual

Property" and together with the Owned Real Property, the "Real Property").
Except as set forth in Items 2.10(b)(i) and (ii) of the Disclosure Schedule, (i)
the Company or a Subsidiary has a valid leasehold interest in the Leased Real
Property and (ii) each Real Property Lease is valid, binding and in full force
and effect with respect to the Company or a Subsidiary, as the case may be, and,
to the knowledge of the Company, to all other parties thereto; no notice of
default or termination under any Real Property Lease is outstanding; no
termination event or condition or uncured default on the part of the Company or
a Subsidiary, as the case may be, exists under any Real Property Lease, and no
event has occurred and no condition exists which, with the giving of notice or
the lapse of time or both, would constitute such a default or termination event
or condition with respect to the Company or a Subsidiary, as the case may be,
or, to the knowledge of the Company or any Subsidiary, any other party thereto,
in each case except for such defaults, terminations, events or conditions as
would not, singly or in the aggregate, have a Material Adverse Effect. The
Company and the Subsidiaries hold their respective leasehold estate under, and
any other interest in each applicable Real Property Lease, free and clear of all
Encumbrances except as set forth in Item 2.10(b)(ii) of the Disclosure Schedule.
The Company has previously delivered or otherwise made available to the
Purchasers true and complete copies of all the Real Property Leases involving

result of the execution of this Agreement or the consummation of the
transactions contemplated hereby.

            (c) The Real Property constitutes all of the real property owned,
leased, occupied or otherwise utilized in connection with the business of the
Company and the Subsidiaries. Except as set forth in Item 2.10(c) of the
Disclosure Schedule, other than the Company and the Subsidiaries, there are no
parties in possession or parties having any current or future right to occupy
any of the Real Property. Except as set forth in Item 2.10(c) of the Disclosure
Schedule, the Real Property is, in all material respects, in good condition and
repair and is sufficient and appropriate for the conduct of the business of the
Company and its Subsidiaries as currently conducted or as currently contemplated
to be conducted. Except as set forth in Item 2.10(c) of the Disclosure Schedule,
to the knowledge of the Company and its Subsidiaries, the Real Property and,
with respect to the Owned Real Property, all plants, buildings and improvements
located thereon conform in all material respects to all applicable building,
zoning and other laws, ordinances, rules and regulations. There exists no
material violation of any covenant, condition, restriction, easement, agreement
or order affecting any portion of the Real Property. Except as set forth in Item
2.10(c) of the Disclosure Schedule, all improvements located on the Real
Property have direct access to a public road adjoining such Real Property. No
such improvements or accessways encroach on land not included in the Real
Property and no such improvement is dependent for its access, operation or
utility on any land, building or other improvement not included in the Real
Property. There is no pending or, to the knowledge of the Company or any
Subsidiary, threatened condemnation proceeding affecting any portion of the Real
Property.

oral notice or claim pertaining to the failure to obtain, or the violation of,

rise to any other material liabilities (whether accrued, absolute, contingent,
unliquidated or otherwise) pursuant to Environmental, Health, and Safety
Requirements, including without limitation, any relating to onsite or offsite
releases or threatened releases of hazardous materials, substances or wastes,
personal injury, property damage or natural resources damage except as would

                                 INDEMNIFICATION

     7.1    INDEMNITY OF PURCHASERS

            The Company agrees to defend, indemnify and hold harmless each
Purchaser from and against, and to reimburse such Purchaser with respect to, all
liabilities, losses, costs and expenses, including, without limitation,
reasonable attorneys' fees and disbursements, asserted against or incurred by
such Purchaser by reason of, arising out of, or in connection with:

            (a) any material breach of any representation or warranty (PROVIDED,
HOWEVER, that if any such representation and warranty is already qualified in
any respect by materiality or as to Material Adverse Effect, for purposes of
this Section 7.1(a), such materiality or Material Adverse Effect qualification
will be in all respects ignored and such representation shall be true and
correct in all material respects without regard to such qualification) contained
in this Agreement and made by the Company or in any document or certificate
delivered by the Company pursuant to the provisions of this Agreement or in
connection with the transactions contemplated thereby;

                                      -24-
<Page>

            (b) any material failure by the Company to perform any agreement
required by this Agreement to be performed thereby; or

            (c) any claim, demand, action, suit, proceeding or investigation
involving the Company or any Subsidiary arising at any time and not disclosed in
the Disclosure Schedule (including the exhibits thereto) and required to be so
disclosed relating to a state of facts, action or omission to act arising on or
prior to the Closing Date or the allegation by any third party of the existence
of any state of facts which, if existing, would constitute a material breach of
any representation or warranty referred to in clause (a) of this Section 7.1.

     7.2    INDEMNIFICATION PROCEDURE

            A Purchaser shall give prompt notice to the Company of any claim for
indemnification arising under Section 7.1. The Company shall have the right to
assume and to control the defense of any such claim with counsel reasonably
acceptable to such Purchaser, at the Company's own cost and expense, including
the cost and expense of reasonable attorneys' fees and disbursements in
connection with such defense, in which event the Company shall not be obligated
to pay the fees and disbursements of separate counsel for such Purchaser in such
action. In the event, however, that such Purchaser's legal counsel shall
determine that defenses may be available to such Purchaser that are different
from or in addition to those available to the Company, in that there could
reasonably be expected to be a conflict of interest if such Purchaser and the
Company have common counsel in any such proceeding, or if the Company has not
assumed the defense of the action or proceedings, then such Purchaser may employ
separate counsel to represent or defend such Purchaser, and the Company shall
pay the reasonable fees and disbursements of such counsel. No settlement of any
such claim or payment in connection with any such settlement shall be made
without the prior consent of the Company which consent shall not be unreasonably
withheld.

                                  ARTICLE VIII

                      AFFIRMATIVE COVENANTS OF THE COMPANY

Exchange Act of 1934 by reason of its registration of Common Stock thereunder if
any Shares are outstanding:

     8.1    FINANCIAL STATEMENTS AND OTHER INFORMATION

            The Company shall deliver to the Purchasers:

            (a) as soon as available but in any event within 30 days after the
end of each monthly accounting period in each fiscal year, unaudited
consolidated statements of income and cash flows of the Company and the
Subsidiaries for such monthly period and for the period from the beginning of
the fiscal year to the end of such month, and unaudited consolidated balance
sheets of the Company and the Subsidiaries as of the end of such monthly period,
setting forth in each case comparisons to the Company's annual budget and to the
corresponding period in the preceding fiscal year, and all such statements shall
be prepared in accordance with generally accepted accounting principles,
consistently applied and shall be certified by the Company's

                                      -25-
<Page>

chief financial officer;

            (b) within 120 days after the end of each fiscal year, consolidating
and consolidated statements of income and cash flows of the Company and the
Subsidiaries for such fiscal year, and consolidating and consolidated balance
sheets of the Company and the Subsidiaries as of the end of such fiscal year,
setting forth in each case comparisons to the Company's annual budget and to the
preceding fiscal year, all prepared in accordance with generally accepted
accounting principles, consistently applied, and accompanied by (i) with respect
to the consolidated portions of such statements, an opinion of an independent
accounting firm of recognized national standing acceptable to the holders of a
majority of the outstanding Series D Preferred Stock, (ii) a certificate from
such accounting firm, addressed to the Board, stating that in the course of its
examination nothing came to its attention that caused it to believe that there
was any default by the Company or any Subsidiary in the fulfillment of or
compliance with any of the terms, covenants, provisions or conditions of any
material agreement to which the Company or any Subsidiary is a party or, if such
accountants have reason to believe any such default by the Company or any
Subsidiary exists, a certificate specifying the nature and period of existence
thereof, and (iii) a copy of such firm's annual management letter to the board
of directors;

            (c) promptly upon receipt thereof, any additional reports,
management letters or other detailed information concerning significant aspects
of the Company's operations or financial affairs given to the Company by its
independent accountants (and not otherwise contained in other materials provided
hereunder);

            (d) at least 30 days, but not more than 90 days, prior to the
beginning of each fiscal year, an annual budget prepared on a monthly basis for
the Company and the Subsidiaries for such fiscal year (displaying anticipated
statements of income and cash flows and balance sheets), and promptly upon
preparation thereof any other significant budgets prepared by the Company or any
Subsidiary and any revisions of such annual or other budgets;

            (e) with reasonable promptness, such other information and financial
data concerning the Company and the Subsidiaries as any Person entitled to
receive information under this Section 8.1 may reasonably request.

            Each of the financial statements referred to in Section 8.1(a) and
8.1(b) hereof shall present fairly the financial position of the Company and the
Subsidiaries in all material respects as of the dates and for the periods stated
therein, subject in the case of the unaudited financial statements to changes
resulting from year-end adjustments.

     8.2    RIGHTS OF INSPECTION

            The Company will permit any representatives designated by the
Purchasers to visit and inspect the property of the Company and the Subsidiaries
and to make copies and extracts therefrom and to discuss the affairs, finances
and accounts of the Company and the Subsidiaries with their respective officers,
all during reasonable business hours, upon reasonable notice and as often as the
Purchasers may reasonably request, subject, in the case of any proprietary or
confidential material, to appropriate measures to ensure the confidentiality
thereof, provided, however, that any such investigation shall be conducted in
such manner as not to

                                      -26-
<Page>

interfere unreasonably with (a) the operation of the business of the Company and
the Subsidiaries or (b) the performance by the officers of the Company and the
Subsidiaries of their respective duties to the Company and the Subsidiary. The
presentation of an executed copy of this Agreement by a Purchaser to the
Company's independent accountants shall constitute the Company's permission to
its independent accountants to participate in discussions with such Persons.

     8.3    RESERVATION OF COMMON STOCK

            The Company shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the conversion of the Series D Preferred Stock, such number of
shares of Common Stock issuable upon the conversion of all outstanding Series D
Preferred Stock. All shares of Common Stock which are so issuable shall, when
issued, be duly and validly issued, fully paid and nonassessable and free from
all taxes, liens and charges. The Company shall take all such actions as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which shares of Common
Stock may be listed (except for official notice of issuance which shall be
immediately transmitted by the Company upon issuance).

     8.4    USE OF PROCEEDS

            The Company shall use the net proceeds (after payment of the Closing
Fee and other expenses related to the offering and sale of the Shares) from the
sale of the Shares to reduce its borrowings under the Credit Agreement and for
working capital and general corporate purposes.

            (b) By either the Purchasers or the Company if the transactions
shall not have occurred on or before September 30, 2001 if the party seeking
termination is not at such time in material breach of this Agreement;

            (c) By the Company if any condition specified in Article VI hereof

no longer be satisfied; or

jurisdiction

                                      -27-

or other governmental authority shall have issued a final, non-appealable order,
decree or ruling or taken any other action (which order, decree or ruling the
parties hereto shall use their best efforts to lift), in each case permanently
restraining, enjoining or otherwise prohibiting the transactions contemplated
hereby.

     9.2    PROCEDURE AND EFFECT OF TERMINATION

            In the event of termination of this Agreement pursuant to Section
9.1 hereof, written notice thereof shall forthwith be given by the terminating
party or parties to the other party or parties hereto, and this Agreement shall
thereupon terminate and become void and have no effect and the transactions
contemplated hereby shall be abandoned without further action by the parties
hereto, except that the provisions of Sections 4.2 and 10.7 hereof shall survive
such termination; provided, however, that such termination shall not relieve any
party hereto of any liability for any breach of this Agreement.

                                   ARTICLE X

                                  MISCELLANEOUS

Company's 2001 fiscal year audited financial statements, regardless of any
investigation made by any party or on its behalf; provided, however, that the
representations and warranties and statements made by the Company in Section 2.7

majority of the Common Stock issued upon conversion of the Series D Preferred
Stock (determined as if all then outstanding Series D Preferred Stock were
converted in accordance with its terms). No other course of dealing between the
Company and the holder of any Preferred Stock or Common Stock or any delay in

Company and adequate reserves therefor have been established. All such Tax

Affiliated Group other than one consisting solely of two or more of the Company

            (viii) each contract or agreement prohibiting it from freely

The Operating Agreements constitute all of the material contracts, agreements,
understandings and arrangements required for the operation of the business of
the Company and the Subsidiaries or which have a material effect thereon. True
and complete copies of all written Operating Agreements without schedules and
exhibits have previously been delivered or otherwise made

                                       -7-

which is material to the provisions of the Operating Agreements.

            (b)    Except as disclosed in Item 2.8 of the Disclosure Schedule,
neither the Company, any Subsidiary, nor, to the Company's knowledge, any other
Person or entity is in breach in any material respect of, or in default in any
material respect under, any Operating Agreement and no event or action has
occurred, is pending or is threatened, which, after the giving of notice,
passage of time or otherwise, would constitute or result in such a material
breach or material default by the Company or any Subsidiary or, to the knowledge
of the Company, any other Person or entity except for such breaches as would not
have a Material Adverse Effect. Neither the Company nor any Subsidiary has
received any notice of default under any Operating Agreement to which it is a
party, which default has not been cured to the satisfaction of, or duly waived
by, the party claiming such default on or before the date hereof. All of the
Operating Agreements on Item 2.8 of the Disclosure Schedule are in all material
respects, valid, binding and enforceable in accordance with their respective

intention of not fully performing its obligations under any Operating Agreement;

breach by the other parties to any Operating Agreement except for such breaches
or anticipated breaches as would not, singly or in the aggregate, have a
Material Adverse Effect.

the Company and the Subsidiaries has good and marketable title to all of its

disposed of in the ordinary course of business since December 31, 2000), free
and clear of all Liens or mortgages, except for (a) any Lien for current taxes
not yet due and payable, (b) restrictions, if any, on the disposition of
securities as may be imposed by federal or applicable state securities laws and
(c) failures of title or Liens as do not materially affect the value,
marketability, operation or the Company's and the Subsidiaries' use of such
assets or as would not, singly or in the aggregate, have a Material Adverse
Effect.

located thereon, free and clear of all Liens, mortgages, encroachments,
restrictions on the use thereof, or other defects in title (collectively,
"Encumbrances"), except matters of record which do not reduce the value or
marketability, or interfere in any material way with use or occupancy of the
Owned Real Property or as would not, singly or in the aggregate, have a Material
Adverse Effect.

            (b)    Item 2.10(b)(i) of the Disclosure Schedule sets forth a true,
correct and complete list of all leases, subleases, licenses and other

Property, the "Real Property"). Except as set forth in Items 2.10(b)(i) and (ii)
of the Disclosure Schedule, (i) the Company or a Subsidiary has a valid
leasehold interest in the Leased Real Property and (ii) each Real Property Lease
is valid, binding and in full force and effect with respect to the Company or a
Subsidiary, as the case may be, and, to the knowledge of the Company, to all
other parties thereto; no notice of default or termination under any Real

default on the part of the Company or a Subsidiary, as the case may be, exists
under any Real Property Lease, and no event has occurred and no condition exists
which, with the giving of notice or the lapse of time or both, would constitute
such a default or termination event or condition with respect to the Company or
a Subsidiary, as the case may be, or, to the knowledge of the Company or any
Subsidiary, any other party thereto, in each case except for such defaults,
terminations, events or conditions as would not, singly or in the aggregate,
have a Material Adverse Effect. The Company and the Subsidiaries hold their
respective leasehold estate under, and any other interest in each applicable
Real Property Lease, free and clear of all Encumbrances except as set forth in
Item 2.10(b)(ii) of the Disclosure Schedule. The Company has previously

leased, occupied or otherwise utilized in connection with the business of the
Company and the Subsidiaries. Except as set forth in Item 2.10(c) of the
Disclosure Schedule, other than the Company and the Subsidiaries, there are no
parties in possession or parties having any current or future right to occupy
any of the Real Property. Except as set forth in Item 2.10(c) of the Disclosure
Schedule, the Real Property is, in all material respects, in good condition and
repair and is sufficient and appropriate for the conduct of the business of the
Company and its Subsidiaries as currently conducted or as currently contemplated
to be conducted. Except as set forth in Item 2.10(c) of the Disclosure Schedule,
to the knowledge of the Company and its Subsidiaries, the Real Property and,
with respect to the Owned Real Property, all plants, buildings and improvements
located thereon conform in all material respects to all applicable building,
zoning and other laws, ordinances, rules and regulations. There exists no
material violation of any covenant, condition, restriction, easement, agreement
or order affecting any portion of the Real Property. Except as set forth in Item

Property have direct access to a public road adjoining such Real Property. No
such improvements or accessways encroach on land not included in the Real

utility on any land, building or other improvement not included in the Real
Property. There is no pending or, to the knowledge of the Company or any
Subsidiary, threatened condemnation proceeding affecting any portion of the Real
Property.

Requirements, including without limitation, any relating to onsite or offsite

            No claim, action, suit, investigation or proceeding shall be pending

                                   ARTICLE VII

                                 INDEMNIFICATION

     7.1    INDEMNITY OF THE PURCHASER

            The Company agrees to defend, indemnify and hold harmless the
Purchaser from and against, and to reimburse the Purchaser with respect to, all
liabilities, losses, costs and expenses, including, without limitation,
reasonable attorneys' fees and disbursements, asserted against or incurred by
the Purchaser by reason of, arising out of, or in connection with:

            (a)    any material breach of any representation or warranty
(PROVIDED, HOWEVER, that if any such representation and warranty is already
qualified in any respect by materiality or as to Material Adverse Effect, for
purposes of this Section 7.1(a), such materiality or Material Adverse Effect
qualification will be in all respects ignored and such representation shall be
true and correct in all material respects without regard to such qualification)
contained in this Agreement and made by the Company or in any document or
certificate delivered by the Company pursuant to the provisions of this
Agreement or in connection with the transactions contemplated thereby;

            (b)    any material failure by the Company to perform any agreement
required by this Agreement to be performed thereby; or

            (c)    any claim, demand, action, suit, proceeding or investigation
involving the Company or any Subsidiary arising at any time and not disclosed in
the Disclosure Schedule (including the exhibits thereto) and required to be so
disclosed relating to a state of facts, action or omission to act arising on or
prior to the Closing Date or the allegation by any third party of the existence
of any state of facts which, if existing, would constitute a material breach of
any representation or warranty referred to in clause (a) of this Section 7.1.

     7.2    INDEMNIFICATION PROCEDURE

            The Purchaser shall give prompt notice to the Company of any claim
for indemnification arising under Section 7.1. The Company shall have the right
to assume and to control the defense of any such claim with counsel reasonably
acceptable to the Purchaser, at the Company's own cost and expense, including
the cost and expense of reasonable attorneys' fees and disbursements in
connection with such defense, in which event the Company shall not be obligated
to pay the fees and disbursements of separate counsel for the Purchaser in such
action. In the event, however, that the Purchaser's legal counsel shall
determine that defenses may be available to the Purchaser that are different
from or in addition to those available to the Company, in that there could
reasonably be expected to be a conflict of interest if the Purchaser and the
Company have common counsel in any such proceeding, or if the Company has not
assumed the defense of the action or proceedings, then the Purchaser may employ
separate counsel to represent or defend the Purchaser, and the Company shall pay
the reasonable fees and disbursements of such counsel. No settlement of any such
claim or payment in connection with any such settlement shall be made without
the prior consent of the Company which consent shall not be unreasonably
withheld.

                      AFFIRMATIVE COVENANTS OF THE COMPANY

            The Company covenants and agrees that until the date on which the
Company shall be obligated to file periodic reports under the Securities
Exchange Act of 1934 by reason of its registration of Common Stock thereunder if
any Shares are outstanding:

     8.1    FINANCIAL STATEMENTS AND OTHER INFORMATION

            The Company shall deliver to the Purchaser:

            (a)    as soon as available but in any event within 30 days after
the end of each monthly accounting period in each fiscal year, unaudited
consolidated statements of income and cash flows of the Company and the
Subsidiaries for such monthly period and for the period from the beginning of
the fiscal year to the end of such month, and unaudited consolidated balance
sheets of the Company and the Subsidiaries as of the end of such monthly period,
setting forth in each case comparisons to the Company's annual budget and to the
corresponding period in the preceding fiscal year, and all such statements shall
be prepared in accordance with generally accepted accounting principles,
consistently applied and shall be certified by the Company's chief financial
officer;

            (b)    within 120 days after the end of each fiscal year,
consolidating and consolidated statements of income and cash flows of the
Company and the Subsidiaries for such fiscal year, and consolidating and
consolidated balance sheets of the Company and the Subsidiaries as of the end of
such fiscal year, setting forth in each case comparisons to the Company's annual
budget and to the preceding fiscal year, all prepared in accordance with
generally accepted accounting principles, consistently applied, and accompanied
by (i) with respect to the consolidated portions of such statements, an opinion
of an independent accounting firm of recognized national standing acceptable to
the holders of a majority of the outstanding Series D Preferred Stock, (ii) a
certificate from such accounting firm, addressed to the Board, stating that in
the course of its examination nothing came to its attention that caused it to
believe that there was any default by the Company or any Subsidiary in the
fulfillment of or compliance with any of the terms, covenants, provisions or
conditions of any material agreement to which the Company or any Subsidiary is a
party or, if such accountants have reason to believe any such default by the
Company or any Subsidiary exists, a certificate specifying the nature and period
of existence thereof, and (iii) a copy of such firm's annual management letter
to the board of directors;

            (c)    promptly upon receipt thereof, any additional reports,
management letters or other detailed information concerning significant aspects
of the Company's operations or financial affairs given to the Company by its
independent accountants (and not otherwise contained in other materials provided
hereunder);

            (d)    at least 30 days, but not more than 90 days, prior to the
beginning of each fiscal year, an annual budget prepared on a monthly basis for
the Company and the Subsidiaries for such fiscal year (displaying anticipated
statements of income and cash flows and balance

                                      -25-

sheets), and promptly upon preparation thereof any other significant budgets
prepared by the Company or any Subsidiary and any revisions of such annual or
other budgets;

            (e)    with reasonable promptness, such other information and
financial data concerning the Company and the Subsidiaries as any Person
entitled to receive information under this Section 8.1 may reasonably request.

            Each of the financial statements referred to in Section 8.1(a) and
8.1(b) hereof shall present fairly the financial position of the Company and the
Subsidiaries in all material respects as of the dates and for the periods stated
therein, subject in the case of the unaudited financial statements to changes
resulting from year-end adjustments.

     8.2    RIGHTS OF INSPECTION

            The Company will permit any representatives designated by the
Purchaser to visit and inspect the property of the Company and the Subsidiaries
and to make copies and extracts therefrom and to discuss the affairs, finances
and accounts of the Company and the Subsidiaries with their respective officers,
all during reasonable business hours, upon reasonable notice and as often as the
Purchaser may reasonably request, subject, in the case of any proprietary or
confidential material, to appropriate measures to ensure the confidentiality
thereof, provided, however, that any such investigation shall be conducted in
such manner as not to interfere unreasonably with (a) the operation of the
business of the Company and the Subsidiaries or (b) the performance by the
officers of the Company and the Subsidiaries of their respective duties to the
Company and the Subsidiary. The presentation of an executed copy of this
Agreement by the Purchaser to the Company's independent accountants shall
constitute the Company's permission to its independent accountants to
participate in discussions with such Persons.

     8.3    RESERVATION OF COMMON STOCK

            The Company shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
issuance upon the conversion of the Series D Preferred Stock, such number of
shares of Common Stock issuable upon the conversion of all outstanding Series D
Preferred Stock. All shares of Common Stock which are so issuable shall, when
issued, be duly and validly issued, fully paid and nonassessable and free from
all taxes, liens and charges. The Company shall take all such actions as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which shares of Common
Stock may be listed (except for official notice of issuance which shall be
immediately transmitted by the Company upon issuance).

     8.4    USE OF PROCEEDS

            The Company shall use the net proceeds (after payment of the Closing
Fee and other expenses related to the offering and sale of the Shares) from the
sale of the Shares to reduce its borrowings under the Credit Agreement and for
working capital and general corporate purposes.

     8.5    OBSERVATION RIGHTS; REGISTRATION RIGHTS

            The Purchaser shall have the right to (a) designate a representative
to attend and observe meetings of the Company's Board of Directors and any
committee thereof and (b) receive all information and consents distributed to
directors. Such representative shall be entitled to reimbursement of, and the
Company shall reimburse such representative for, all of its reasonable
out-of-pocket expenses incurred in connection with attending regular and special
meetings of the Board of Directors and any meeting of any committee of the Board
of Directors. Notwithstanding the foregoing, upon the request of the underwriter
in connection with an initial Public Offering (as defined in the Stockholders'
Agreement), the Purchaser will discuss the termination of the rights provided in
this Section 8.5.

            The Company shall use its best efforts to obtain the signatures of
all parties to the Registration Rights Agreement. If by the 30th day after the
date hereof, the Company has not obtained the signatures of all parties to the
Registration Rights Agreement, then the Company shall execute, and shall cause
those parties holding in the aggregate at least 95% of the Paid-In Shares (as
defined in the Stockholders' Agreement) to execute the Side Letter attached to
the Subordinate Registration Rights Agreement as Exhibit B thereto, dated the
45th day after the date hereof (the "Side Letter"). Without the prior written
consent of the Purchaser, the Company agrees not to amend or waive any provision
of the Side Letter so as to disproportionately and adversely affect the
Purchaser relative to the other addressees of the Side Letter.

            (a)    By mutual written consent of the Purchaser and the Company;

            (b)    By the Company if any condition specified in Article VI
hereof has not been met or waived by the Company at such time as such conditions
can no longer be satisfied;

            (c)    By the Purchaser if any condition specified in Article V
hereof has not been met or waived by the Purchaser at such time as such
condition can no longer be satisfied; or

            (d)    By either the Purchaser or the Company if (i) a court of
competent jurisdiction or other governmental authority shall have issued a
final, non-appealable order, decree or ruling or taken any other action (which
order, decree or ruling the parties hereto shall use their best efforts to
lift), in each case permanently restraining, enjoining or otherwise prohibiting
the transactions contemplated hereby or (ii) the transactions contemplated
hereby shall not have occurred on or before December 28, 2001 if the party
seeking termination is not at such time in material breach of this Agreement.

            In the event of termination of this Agreement pursuant to Section
9.1 hereof, written notice thereof shall forthwith be given by the terminating
party or parties to the other party or parties hereto, and this Agreement shall
thereupon terminate and become void and have no effect and the transactions
contemplated hereby shall be abandoned without further action by the parties
hereto, except that the provisions of Sections 4.2 and 10.7 hereof shall survive
such termination; provided, however, that such termination shall not relieve any
party hereto of any liability for any breach of this Agreement.

                                    ARTICLE X

                                  MISCELLANEOUS

Stock were converted in accordance with its terms). No other course of dealing
