         or any development involving a prospective material adverse change, in
         the condition, financial or otherwise, or in the earnings, business or

         that set forth in the Final Memorandum (exclusive of any amendments or

         in all material respects in the Memorandum and proceedings that would

         taken as a whole, or on the power or ability of the Company or the
         Guarantors to perform their respective obligations under this
         Agreement, the Indenture, the Registration Rights Agreement, the
         Securities (in the case of the Company) and the Guarantee (in the case

         the Final Memorandum.

                  (m)      Each of the Company and its subsidiaries has all
         necessary consents, authorizations, approvals, orders, certificates and
         permits of and from, and has made all declarations and filings with,

         self-regulatory organizations and all courts and other tribunals, to
         own, lease, license and use its properties and assets and to conduct
         its business in the manner described in the Final Memorandum, except to
         the extent that the failure to obtain such consents, authorizations,
         approvals, orders, certificates and permits or make such declarations
         and filings would not have a material adverse effect on the Company and
         its subsidiaries, taken as a whole. Neither the Company nor any of its
         subsidiaries has received any notice of proceedings relating to the
         revocation or modification of any such consent, authorization,
         approval, order, certificate or permit which, singly or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would result in a material adverse change in the condition,
         financial or otherwise, or in the earnings, business or operations of
         the Company and its subsidiaries, taken as a whole, except as described
         in or contemplated by the Final Memorandum.


                                       4

                  (n)      The Company and its subsidiaries (i) are in
         compliance with any and all applicable foreign, federal, state and
         local laws and regulations relating to the protection of human health
         and safety, the environment or hazardous or toxic substances or wastes,
         pollutants or contaminants ("Environmental Laws"), (ii) have received
         all permits, licenses or other approvals required of them under
         applicable Environmental Laws to conduct their respective businesses
         and (iii) are in compliance with all terms and conditions of any such
         permit, license or approval, except where such noncompliance with
         Environmental Laws, failure to receive required permits, licenses or
         other approvals or failure to comply with the terms and conditions of
         such permits, licenses or approvals would not, singly or in the
         aggregate, have a material adverse effect on the Company and its
         subsidiaries, taken as a whole.

                  (o)      In the ordinary course of business, the Company
         conducts a periodic review of the effect of Environmental Laws on the
         business, operations and properties of the Company and its
         subsidiaries, in the course of which it identifies and evaluates
         associated costs and liabilities (including, without limitation, any
         capital or operating expenditures required for clean-up, closure of
         properties or compliance with Environmental Laws or any permit, license
         or approval, any related constraints on operating activities and any
         potential liabilities to third parties). On the basis of such review,
         the Company has reasonably concluded that such associated costs and
         liabilities would not, singly or in the aggregate, have a material
         adverse effect on the Company and its subsidiaries, taken as a whole.

                  (p)      Neither the Company nor the Guarantors, after giving
         effect to the offering and sale of the Securities and the application
         of the proceeds thereof as described in the Final Memorandum, will be
         an "investment company" as such term is defined in the Investment
         Company Act of 1940, as amended.

                  (q)      None of the Company, any Guarantor or any affiliate
         (as defined in Rule 501(b) of Regulation D under the Securities Act, an
         "Affiliate") of the Company or any Guarantor has directly, or through
         any agent, (i) sold, offered for sale, solicited offers to buy or
         otherwise negotiated in respect of, any security (as defined in the
         Securities Act) which is or will be integrated with the sale of the
         Securities in a manner that would require the registration under the
         Securities Act of the Securities or (ii) engaged in any form of general
         solicitation or general advertising in connection with the offering of
         the Securities, (as those terms are used in Regulation D under the
         Securities Act) or in any manner involving a public offering within the
         meaning of Section 4(2) of the Securities Act.

                  (r)      None of the Company, any Guarantor, their Affiliates
         or any person acting on its or their behalf has engaged or will engage
         in any directed selling efforts (within the meaning of Regulation S)
         with respect to the Securities and the Company, any Guarantor and their
         Affiliates and any person acting on its or their behalf have complied
         and will comply with the offering restrictions requirement of
         Regulation S.

                  (s)      It is not necessary in connection with the offer,
         sale and delivery of the Securities to the Placement Agents in the
         manner contemplated by this Agreement to register the Securities or the
         Guarantees under the Securities Act or to qualify the Indenture under
         the Trust Indenture Act of 1939, as amended.

         the Final Memorandum.

                  (w)      The Company and its subsidiaries have good and
         marketable title in fee simple to all real property and good and
         marketable title to all personal property owned by them which is
         material to the business of the Company and its subsidiaries, in each
         case free and clear of all liens, encumbrances and defects except such
         as are described in the Final Memorandum or such as do not materially
         affect the value of such property and do not interfere with the use
         made and proposed to be made of such property by the Company and its
         subsidiaries: and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not

         of such property and buildings by the Company and its subsidiaries, in
         each case except as described in or contemplated by the Final
         Memorandum.

         can acquire on reasonable terms, all material patents, patent rights,

         subsidiaries has received any notice of infringement of or conflict
         with asserted rights of others with respect to any of the foregoing
         which, singly or in the aggregate, if the subject of an unfavorable
         decision, ruling or finding, would result in any material adverse
         change in the condition, financial or otherwise, or in the earnings,
         business or operations of the Company and its subsidiaries, taken as a
         whole.

                  (y)      No material labor dispute with the employees of the
         Company or any of its subsidiaries exists, except as described in or
         contemplated by the Final Memorandum, or, to the knowledge of the
         Company, is imminent; and the Company is not aware of any existing,
         threatened or imminent labor disturbance by the employees of any of its
         principal suppliers, manufacturers or contractors that could result in
         any material adverse change in the condition, financial or otherwise,
         or in the earnings, business or operations of the Company and its
         subsidiaries, taken as a whole.

                  (z)      The Company and each of its subsidiaries are insured
         by insurers of recognized financial responsibility against such losses
         and risks and in such amounts as are prudent and customary in the
         businesses in which they are engaged; neither the Company nor any such
         subsidiary has been refused any insurance coverage sought or applied
         for; and neither the Company nor any such subsidiary has any reason to
         believe that it will not be able to renew its existing insurance
         coverage as and when such coverage expires or to obtain similar
         coverage from similar insurers as may be necessary to continue its
         business at a cost that would not materially and adversely affect the
         condition, financial or otherwise, or the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole,
         except as described in or contemplated by the Final Memorandum.

                  (aa)     The Company and each of its subsidiaries maintain a
         system of internal accounting controls sufficient to provide reasonable
         assurance that (1) transactions are executed in accordance with
         management's general or specific authorizations; (2) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset accountability; (3) access to assets is permitted only
         in accordance with management's general or specific authorization; and
         (4) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect to any differences.

         2.       Agreements to Sell and Purchase. The Company hereby agrees to
sell to the several Placement Agents, and each Placement Agent, upon the basis
of the representations and warranties herein contained, but subject to the
conditions hereinafter stated, agrees, severally and not jointly, to purchase
from the Company the respective principal amount of Securities set forth in
Schedule I hereto opposite its name at a purchase price of 106.956725% of the
principal amount, plus accrued interest thereon from September 15, 2003 to but
excluding the Closing Date thereof (the "Purchase Price").

                  The Company and the Guarantors hereby agree that, without the
prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
Placement Agents, it will not, during the period beginning on the date hereof
and continuing to and including the Closing Date, offer, sell, contract to sell
or otherwise dispose of any debt of the Company or any Guarantor or warrants to
purchase debt of the Company or any Guarantor substantially similar to the
Securities or the Guarantees (other than the sale of the Securities under this
Agreement.)

         3.       Terms of Offering. You have advised the Company and the
Guarantors that the Placement Agents will make an offering of the Securities
purchased by the Placement Agents hereunder on the terms to be set forth in the
Final Memorandum, as soon as practicable after this Agreement is entered into as
in your judgment is advisable.

         4.       Payment and Delivery. Payment for the Securities shall be made
to the Company in Federal or other funds immediately available in New York City
against delivery of such Securities for the respective accounts of the several
Placement Agents at 10:00 a.m., New York City time, on November 26, 2003, or at
such other time on the same or such other date, not later than December 8, 2003,
as shall be designated in writing by you. The time and date of such payment are
hereinafter referred to as the "Closing Date."

                  Certificates for the Securities shall be in definitive form or
global form, as specified by you, and registered in such names and in such
denominations as you shall request in writing not later than one full business
day prior to the Closing Date. The certificates evidencing the Securities shall
be delivered to you on the Closing Date for the respective accounts of the
several Placement Agents, with any transfer taxes payable in connection with the
transfer of the Securities to the Placement Agents duly paid, against payment of
the Purchase Price therefor.

         5.       Conditions to the Placement Agents' Obligations. The several
obligations of the Placement Agents to purchase and pay for the Securities on
the Closing Date are subject to the following conditions:

                  (a)      Subsequent to the execution and delivery of this
         Agreement and prior to the Closing Date:

                           (i)      there shall not have occurred any
                  downgrading, nor shall any notice have been given of any
                  intended or potential downgrading or of any review for a
                  possible change that does not indicate the direction of the
                  possible change, in the rating accorded the Company or any of
                  the Company's securities or in the rating outlook for the
                  Company by any "nationally recognized statistical rating
                  organization," as such term is defined for purposes of Rule
                  436(g)(2) under the Securities Act; and

                           (ii)     there shall not have occurred any change, or
                  any development involving a prospective change, in the
                  condition, financial or otherwise, or in the earnings,
                  business or operations of the Company and its subsidiaries,
                  taken as a whole, from that set forth in the Final Memorandum
                  (exclusive of any amendments or supplements thereto subsequent
                  to the date of this Agreement) that, in your judgment, is
                  material and adverse and that makes it, in your judgment,
                  impracticable to market the Securities on the terms and in the
                  manner contemplated in the Final Memorandum.

                  (b)      The Placement Agents shall have received on the
         Closing Date a certificate, dated the Closing Date and signed by an
         executive officer of the Company and each Guarantor, to the effect set
         forth in Section 5(a)(i) and to the effect that the representations and
         warranties of the Company and such Guarantor contained in this
         Agreement are true and correct as of the Closing Date and the Company
         and such Guarantor has complied with all of the agreements and
         satisfied all of the conditions on its part to be performed or
         satisfied hereunder on or before the Closing Date.

                  The officer signing and delivering such certificate may rely
         upon the best of his or her knowledge as to proceedings threatened.

         satisfactory to the Placement Agents, from Ernst & Young LLP,

                  (g)      The Sixth Amendment to the Credit Agreement shall

Agreement, each of the Company and the Guarantors, jointly and severally,

                  (c)      If, during such period after the date hereof and
         prior to the date on which all of the Securities shall have been sold
         by the Placement Agents, any event shall occur or condition exist as a

         as so amended or supplemented will not, in the light of the

         will comply with applicable law.

                  of the Securities, or possession or distribution of the
                  Memorandum or any other offering or publicity material
                  relating to the Securities, in any country or jurisdiction
                  where action for that purpose is required;

                           (iii)    such Placement Agent will comply with all

                  have been registered under the Securities Act and may not be
                  offered or sold within the United States or to, or for the
                  account or benefit of, U.S. persons except in accordance with

                  days after the later of the commencement of the offering and
                  the Closing Date, only in accordance with Rule 903 of
                  Regulation S or as otherwise permitted in Section 7(a);
                  accordingly, neither such Placement Agent, its Affiliates nor
                  any persons acting on its or their behalf have engaged or will
                  engage in any directed selling efforts (within the meaning of
                  Regulation S) with respect to the Securities, and any such
                  Placement Agent, its Affiliates and any such persons have

                  businesses or otherwise in circumstances which have not
                  resulted and will not result in an offer to the public in the
                  United Kingdom within the meaning of the Public Offers of
                  Securities Regulations 1995; (B) complied and will comply with
                  all applicable provisions of the Financial Services Act 1986
                  with respect to anything done by it in relation to the
                  Securities in, from or otherwise involving the United Kingdom,
                  and (C) only issued or passed on and will only issue or pass
                  on in the United Kingdom any document received by it in
                  connection with the issue of the Securities to a person who is
                  of a kind described in Article 11(3) of the Financial Services

                           (vii)    such Placement Agent agrees that, at or
                  prior to confirmation of sales of the Securities, it will have
                  sent to each distributor, dealer or person receiving a selling
                  concession, fee or other remuneration that purchases the
                  Securities from it during the restricted period a confirmation
                  or notice to substantially the following effect:

                           "The Securities covered hereby have not been
                  registered under the U.S. Securities Act of 1933 (the
                  "Securities Act") and may not be offered and sold within the

                  them by Regulation S."

                           Terms used in this Section 7(b) have the meanings
                  given to them by Regulation S.

         8.       Indemnity and Contribution. (a) Each of the Company and the
Guarantors agrees, jointly and severally, to indemnify and hold harmless each
Placement Agent, each person, if any, who controls any Placement Agent within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act and each affiliate of any Placement Agent within the meaning of
Rule 405 under the Securities Act from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in either Memorandum (as amended or supplemented if
the Company or the Guarantors shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein in the light of the
circumstances under which they were made not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to any Placement Agent furnished to the Company and the Guarantors in
writing by such Placement Agent through you expressly for use therein.

                  (b)      Each Placement Agent agrees, severally and not
         jointly, to indemnify and hold harmless the Company, the Guarantors,
         their directors and officers and each person, if any, who controls the
         Company or the Guarantors within the meaning of either Section 15 of
         the Securities Act or Section 20 of the Exchange Act to the same extent
         as the foregoing indemnity from the Company and the Guarantors to such
         Placement Agent, but only with reference to information relating to
         such Placement Agent furnished to the Company and the Guarantors in
         writing by such Placement Agent through you expressly for use in either
         Memorandum or any amendments or supplements thereto.

                  (c)      In case any proceeding (including any governmental
         investigation) shall be instituted involving any person in respect of
         which indemnity may be sought pursuant to Section 8(a) or 8(b), such
         person (the "indemnified party") shall promptly notify the person
         against whom such indemnity may be sought (the "indemnifying party") in
         writing and the indemnifying party, upon request of the indemnified
         party, shall retain counsel reasonably satisfactory to the indemnified
         party to represent the indemnified party and any others the
         indemnifying party may designate in such proceeding and shall pay the
         fees and disbursements of such counsel related to such proceeding. In
         any such proceeding, any indemnified party shall have the right to
         retain its own counsel, but the fees and expenses of such counsel shall
         be at the expense of such indemnified party unless (i) the indemnifying
         party and the indemnified party shall have mutually agreed to the
         retention of such counsel or (ii) the named parties to any such
         proceeding (including any impleaded parties) include both the
         indemnifying party and the indemnified party and representation of both
         parties by the same counsel would be inappropriate due to actual or
         potential differing interests between them. It is understood that the
         indemnifying party shall not, in respect of the legal expenses of any
         indemnified party in connection with any proceeding or related
         proceedings in the same jurisdiction, be liable for the fees and
         expenses of more than one separate firm (in addition to any local
         counsel) for all such indemnified parties and that all such fees and
         expenses shall be reimbursed as they are incurred. Such firm shall be
         designated in writing by Morgan Stanley & Co. Incorporated, in the case
         of parties indemnified pursuant to Section 8(a), and by the Company, in
         the case of parties indemnified pursuant to Section 8(b). The
         indemnifying party shall not be liable for any settlement of any
         proceeding effected without its written consent, but if settled with
         such consent or if there be a final judgment for the plaintiff, the
         indemnifying party agrees to indemnify the indemnified party from and
         against any loss or liability by reason of such settlement or judgment.
         Notwithstanding the foregoing sentence, if at any time an indemnified
         party shall have requested an indemnifying party to reimburse the
         indemnified party for fees and expenses of counsel as contemplated by
         the second and third sentences of this paragraph, the indemnifying
         party agrees that it shall be liable for any settlement of any
         proceeding effected without its written consent if (i) such settlement
         is entered into more than 30 days after receipt by such indemnifying
         party of the aforesaid request and (ii) such indemnifying party shall
         not have reimbursed the indemnified party in accordance with such
         request prior to the date of such settlement. No indemnifying party
         shall, without the prior written consent of the indemnified party,
         effect any settlement of any pending or threatened proceeding in
         respect of which any indemnified party is or could have been a party
         and indemnity could have been sought hereunder by such indemnified
         party, unless such settlement includes an unconditional release of such
         indemnified party from all liability on claims that are the subject
         matter of such proceeding.

                  (d)      To the extent the indemnification provided for in
         Section 8(a) or 8(b) is unavailable to an indemnified party or
         insufficient in respect of any losses, claims, damages or liabilities
         referred to therein, then each indemnifying party under such paragraph,
         in lieu of indemnifying such indemnified party thereunder, shall
         contribute to the amount paid or payable by such indemnified party as a
         result of such losses, claims, damages or liabilities (i) in such
         proportion as is appropriate to reflect the relative benefits received
         by the Company and the Guarantors, on the one hand, and the Placement
         Agents, on the other hand, from the offering of the Securities or (ii)
         if the allocation provided by clause 8(d)(i) above is not permitted by
         applicable law, in such proportion as is appropriate to reflect not
         only the relative benefits referred to in clause 8(d)(i) above but also
         the relative fault of the Company and the Guarantors, on the one hand,
         and of the Placement Agents, on the other hand, in connection with the
         statements or omissions that resulted in such losses, claims, damages
         or liabilities, as well as any other relevant equitable considerations.
         The relative benefits received by the Company and the Guarantors, on
         the one hand, and the Placement Agents, on the other hand, in
         connection with the offering of the Securities shall be deemed to be in
         the same respective proportions as the net proceeds from the offering
         of the Securities (before deducting expenses) received by the Company
         and the total discounts and commissions received by the Placement
         Agents in respect thereof, bear to the aggregate offering price of the
         Securities. The relative fault of the Company and the Guarantors, on
         the one hand, and of the Placement Agents, on the other hand, shall be
         determined by reference to, among other things, whether the untrue or
         alleged untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied by
         the Company and the Guarantors or by the Placement Agents and the
         parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such statement or omission. The
         Placement Agents' respective obligations to contribute pursuant to this
         Section 8 are several in proportion to the respective principal amount
         of Securities they have purchased hereunder, and not joint.

                  (e)      The Company, the Guarantors and the Placement Agents
         agree that it would not be just or equitable if contribution pursuant
         to this Section 8 were determined by pro rata allocation (even if the
         Placement Agents were treated as one entity for such purpose) or by any
         other method of allocation that does not take account of the equitable
         considerations referred to in Section 8(d). The amount paid or payable
         by an indemnified party as a result of the losses, claims, damages and
         liabilities referred to in Section 8(d) shall be deemed to include,
         subject to the limitations set forth above, any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending any such action or claim. Notwithstanding
         the provisions of this Section 8, no Placement Agent shall be required
         to contribute any amount in excess of the amount by which the total
         price at which the Securities resold by it in the initial placement of
         such Securities were offered to investors exceeds the amount of any
         damages that such Placement Agent has otherwise been required to pay by
         reason of such untrue or alleged untrue statement or omission or
         alleged omission. No person guilty of fraudulent misrepresentation
         (within the meaning of Section 11(f) of the Securities Act) shall be
         entitled to contribution from any person who was not guilty of such
         fraudulent misrepresentation. The remedies provided for in this Section
         8 are not exclusive and shall not limit any rights or remedies which
         may otherwise be available to any indemnified party at law or in
         equity.

                  (f)      The indemnity and contribution provisions contained
         in this Section 8 and the representations, warranties and other
         statements of the Company and the Guarantors contained in this
         Agreement shall remain operative and in full force and effect
         regardless of (i) any termination of this Agreement, (ii) any
         investigation made by or on behalf of any Placement Agent, any person
         controlling any Placement Agent or any affiliate of any Placement Agent
         or by or on behalf of the Company, the Guarantors, their officers or
         directors or any person controlling the Company or the Guarantors and
         (iii) acceptance of and payment for any of the Securities.

         9.       Termination. The Placement Agents may terminate this Agreement
by notice given by you to the Company, if after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on, or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange, the Nasdaq National
Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange
or the Chicago Board of Trade, (ii) trading of any securities of the Company
shall have been suspended on any exchange or in any over-the-counter market,
(iii) a material disruption in securities settlement, payment or clearance
services in the United shall have occurred, (iv) any moratorium on commercial
banking activities shall have been declared by Federal or New York State
authorities or (v) there shall have occurred any outbreak or escalation of
hostilities, or any change in financial markets or any calamity or crisis that,
in your judgment, is material and adverse and which, singly or together with any
other event specified in this clause (v), makes it, in your judgment,
impracticable or inadvisable to proceed with the offer, sale or delivery of the
Securities on the terms and in the manner contemplated in the Final Memorandum.

         10.      Effectiveness; Defaulting Placement Agents. This Agreement
shall become effective upon the execution and delivery hereof by the parties
hereto.

         If, on the Closing Date, any one or more of the Placement Agents shall
fail or refuse to purchase Securities that it or they have agreed to purchase
hereunder on such date, and the aggregate principal amount of Securities which
such defaulting Placement Agent or Placement Agents agreed but failed or refused
to purchase is not more than one-tenth of the aggregate principal amount of
Securities to be purchased on such date, the other Placement Agents shall be
obligated severally in the proportions that the principal amount of Securities
set forth opposite their respective names in Schedule I bears to the aggregate
principal amount of Securities set forth opposite the names of all such
non-defaulting Placement Agents, or in such other proportions as you may
specify, to purchase the Securities which such defaulting Placement Agent or
Placement Agents agreed but failed or refused to purchase on such date; provided
that in no event shall the principal amount of Securities that any Placement
Agent has agreed to purchase pursuant to this Agreement be increased pursuant to
this Section 10 by an amount in excess of one-ninth of such principal amount of
Securities without the written consent of such Placement Agent. If, on the
Closing Date any Placement Agent or Placement Agents shall fail or refuse to
purchase Securities which it or they have agreed to purchase hereunder on such
date and the aggregate principal amount of Securities with respect to which such
default occurs is more than one-tenth of the aggregate principal amount of
Securities to be purchased on such date, and arrangements satisfactory to you
and the Company for the purchase of such Securities are not made within 36 hours
after such default, this Agreement shall terminate without liability on the part
of any non-defaulting Placement Agent or of the Company or of the Guarantors. In
any such case either you or the Company shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Final Memorandum or in any other documents or
arrangements may be effected. Any action taken under this paragraph shall not
relieve any defaulting Placement Agent from liability in respect of any default
of such Placement Agent under this Agreement.


                                       16

         If this Agreement shall be terminated by the Placement Agents, or any
of them, because of any failure or refusal on the part of the Company or the
Guarantors to comply with the terms or to fulfill any of the conditions of this
Agreement, or if for any reason the Company shall be unable to perform its
obligations under this Agreement, the Company will reimburse the Placement
Agents or such Placement Agents as have so terminated this Agreement with
respect to themselves, severally, for all out-of-pocket expenses (including the
fees and disbursements of their counsel) reasonably incurred by such Placement
Agents in connection with this Agreement or the offering contemplated hereunder.

         Attach draft opinion of the counsel for the Company and the Guarantors
to be delivered pursuant to Section 5(c) of the Placement Agreement to the
effect that:

         A.       The Company has been duly incorporated, is validly existing as
a corporation in good standing under the laws of the jurisdiction of its
incorporation, has the corporate power and authority to own its property and to
conduct its business as described in the Final Memorandum and is duly qualified
to transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such
qualification, except to the extent that the failure to be so qualified or be in
good standing would not have a material adverse effect on the Company and its
subsidiaries, taken as a whole.

         B.       Each subsidiary of the Company has been duly incorporated or
organized, is validly existing as a corporation or as a limited liability
company in good standing under the laws of the jurisdiction of its incorporation
or organization, has the corporate power and authority to own its property and
to conduct its business as described in the Final Memorandum and is duly
qualified to transact business and is in good standing in each jurisdiction in
which the conduct of its business or its ownership or leasing of property
requires such qualification, except to the extent that the failure to be so
qualified or be in good standing would not have a material adverse effect on the
Company and its subsidiaries, taken as a whole; all of the issued shares of
capital stock, and all membership units or interests, of each subsidiary of the
Company have been duly and validly authorized and issued, are fully paid and
non-assessable, and are owned directly by the Company, free and clear of all
liens, encumbrances, equities or claims.

         C.       The Placement Agreement has been duly authorized, executed and
delivered by the Company and the Guarantors.

         D.       All shares of common stock of the Company and its subsidiaries

         E.       The Securities have been duly authorized, executed and
delivered by the Company.

         F.       The Guarantee by each Guarantor has been duly authorized,

                                      A-1

         I.       The Sixth Amendment to the Credit Agreement has been duly
authorized, executed and delivered by the Company and the Guarantors named
therein and is in full force and effect.

         J.       The execution and delivery by the Company and the Guarantors
of, and the performance by the Company and the Guarantors of their respective
obligations under, the Placement Agreement, the Indenture, the Registration
Rights Agreement, the Securities (in the case of the Company) and the Guarantees
(in the case of the Guarantors) will not contravene any provision of applicable
law or the articles of incorporation or by-laws of the Company or the Guarantors
or, to the best of such counsel's knowledge, any agreement or other instrument
binding upon the Company or any of its subsidiaries that is material to the
Company and its subsidiaries, taken as a whole, (including, but not limited to,
the Credit Agreement as amended by the Sixth Amendment) or, to the best of such
counsel's knowledge, any judgment, order or decree of any governmental body,
agency or court having jurisdiction over the Company or any subsidiary, and no
consent, approval, authorization or order of, or qualification with, any
governmental body or agency is required for the performance by the Company or
the Guarantors of their respective obligations under the Placement Agreement,
the Indenture, the Registration Rights Agreement, the Securities (in the case of
the Company) and the Guarantees (in the case of the Guarantors), except such as
may be required by the securities or Blue Sky laws of the various states in
connection with the offer and sale of the Securities and by Federal and state
securities laws with respect to the Company's and the Guarantors' obligations
under the Registration Rights Agreement.

         K.       After due inquiry, such counsel does not know of any legal or
governmental proceedings pending or threatened to which the Company or any of
its subsidiaries is a party or to which any of the properties of the Company or
any of its subsidiaries is subject other than proceedings fairly summarized in
all material respects in the Final Memorandum and proceedings which such counsel
believes are not likely to have a material adverse effect on the Company and its
subsidiaries, taken as a whole, or on the power or ability of the Company and
the Guarantors to perform their respective obligations under the Placement
Agreement, the Indenture, the Registration Rights Agreement, the Securities (in
the case of the Company), and the Guarantees (in the case of the Guarantors) or
to consummate the transactions contemplated by the Final Memorandum.

         L.       After due inquiry, to the best of our knowledge, the Company
and its subsidiaries (i) are in compliance with any and all applicable foreign,
federal, state and local laws and regulations relating to the protection of
human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("Environmental Laws"), (ii) have received
all permits, licenses or other approvals required of them under applicable
Environmental Laws to conduct their respective businesses and (iii) are in
compliance with all terms and conditions of any such permit, license or
approval, except where such noncompliance with Environmental Laws, failure to
receive required permits, licenses or other approvals or failure to comply with
the terms and conditions of such permits, licenses or approvals would not,
singly or in the aggregate, have a material adverse effect on the Company and
its subsidiaries, taken as a whole.

         M.       Each of the Company and the Guarantors are not, and after
giving effect to the offering and sale of the Securities and the application of
the proceeds thereof as described in the Final Memorandum, will not be an
"investment company" as such term is defined in the Investment Company Act of
1940, as amended.

         N.       The statements related to legal matters, documents or
proceedings included in the Final Memorandum under the captions "Risk
Factors--Environmental regulation imposes substantial costs and limitations on
our operations," "Description of Notes," "Description of Capital Stock,"
"Description of Certain Indebtedness," "Certain ERISA Considerations," "Private
Placement," and "Transfer Restrictions," and in "Item 1 -
Business--Environmental Matters," "Item 3 - Legal Proceedings," "Item 1 -
Business - Section 201 Investigation," "Item 1 - Business--Risk Factors--Risks
Related to Our Business--Environmental regulation imposes substantial costs and
limitations on our operations" and "Item 13 - Certain Relationships and Related
Transactions" of the Company's most recent annual report on Form 10-K and in
"Item 1 - Legal Proceedings," of each quarterly report on Form 10-Q included or
incorporated by reference in the Final Memorandum, in each case fairly summarize
in all material respects such matters, documents or proceedings.

         O.       The statements in the Final Memorandum under the caption
"United States Federal Income Tax Considerations," insofar as such statements
constitute a summary of the United States federal tax laws referred to therein,
are accurate and fairly summarize in all material respects the United States
federal tax laws referred to therein.

         P.       Such counsel (i) is of the opinion that each document
incorporated by reference in the Final Memorandum (except for financial
statements and schedules and other financial and statistical data included
therein as to which such counsel need not express any opinion), complied as to
form when filed with the Commission in all material respects with the Exchange
Act and the rules and regulations of the Commission thereunder and (ii) has no
reason to believe that (except for financial statements and schedules and other
financial and statistical data as to which such counsel need not express any
belief) the Final Memorandum when issued contained, or as of the date such
opinion is delivered contains, any untrue statement of a material fact or
omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

         Q.       Based upon the representations, warranties and agreements of
the Company in the Placement Agreement and of the Placement Agents in the
Placement Agreement, it is not necessary in connection with the offer, sale and
delivery of the Securities to the Placement Agents under the Placement Agreement
or in connection with the initial resale of such Securities by the Placement
Agents in accordance with the Placement Agreement to register the Securities
under the Securities Act of 1933, as amended, or to qualify the Indenture under
the Trust Indenture Act of 1939, it being understood that no opinion is
expressed as to any subsequent resale of any Security.


                                      A-3

         R.       Each of the Company and its subsidiaries has all necessary
certificates, orders, permits, licenses, authorizations, consents and approvals
of and from, and has made all declarations and filings with, all federal, state
and local governmental authorities, all self-regulatory organizations and all
courts and tribunals, to own, lease, license and use its properties and assets
and to conduct its business in the manner described in the Final Memorandum, and
neither the Company nor any of its subsidiaries has received any notice of
proceedings relating to revocation or modification of any such certificates,
orders, permits, licenses, authorizations, consents or approvals, nor is the
Company or any of its subsidiaries in violation of, or in default under, any
federal, state or local law, regulation, rule, decree, order or judgment
applicable to the Company or any of its subsidiaries the effect of which, singly
or in the aggregate, would have a material adverse effect on the prospects,
condition, financial or otherwise, or in the earnings, business or operations of
the Company and its subsidiaries, taken as a whole, except as described in the
Final Memorandum.

         With respect to paragraph P above, counsel may state that his or her
opinion and belief are based upon his or her participation in the preparation of
the Final Memorandum (and any amendments or supplements thereto), and review and
discussion of the contents thereof and review of the documents incorporated by
reference therein, but are without independent check or verification except with
respect to paragraphs N and O.
