aggregate of $150,000,000 principal amount of its 12 3/4% Senior Subordinated
Notes due 2005 (the "Securities"). The securities will be unconditionally
guaranteed by the Guarantor (the "Guarantee"). The Securities are to be issued

          The Securities will be offered and sold to you without being

reliance on an exemption therefrom. The Company has prepared a preliminary
offering memorandum, dated April 5, 1995 (such preliminary offering memorandum
being hereinafter referred to as the

 
                                       2

Purchaser for use in connection with the offering of the Securities, being
hereinafter referred to as the "Offering Memorandum"), setting forth information
regarding the Company and the Securities.  The Company hereby confirms that it
has authorized the use of the Preliminary Offering Memorandum and the Offering
Memorandum in connection with the offering and resale of the Securities to such
potential purchasers as specified therein.

          The Company understands that you propose to make an offering of the
Securities on the terms set forth in the Offering Memorandum, as soon as you
deem advisable after this Agreement has been executed and delivered only (i) to
persons in the United States whom you reasonably believe to be qualified
institutional buyers ("Qualified Institutional Buyers") as defined in Rule 144A
under the 1933 Act, as such rule may be amended from time to time ("Rule 144A"),
in transactions under Rule 144A, (ii) to a limited number of other institutional
"accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under
Regulation D of the 1933 Act ("Accredited Investors")) in private sales exempt
from registration under the 1933 Act and/or (iii) to non-U.S. persons outside
the United States to whom offers and sales of the Securities may be made in
reliance upon Regulation S under the 1933 Act.

          The holders of the Securities will be entitled to the benefits of a
Registration Rights Agreement, in substantially the form attached hereto as
Exhibit A with such changes as shall be agreed to by the parties hereto (the
"Registration Rights Agreement"), pursuant to which the Company has agreed to
use its best efforts to file within 30 days of the date of original issue of the
Securities a registration statement (the "Registration Statement") with the
Securities and Exchange Commission (the "Commission") registering the Securities
or the Exchange Securities referred to in the Registration Rights Agreement

     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by the Initial Purchaser expressly for use therein.

 
                                       3

          (ii)   The Preliminary Offering Memorandum, the Offering Memorandum

     ("Associated") and its subsidiaries as of the dates indicated and the

     and in good standing under the laws of the State of Illinois with corporate
     power and authority under such laws to own, lease and operate its

     Memorandum; and the Company is duly qualified to transact business as a
     foreign corporation and is in good standing in each other jurisdiction in
     which it owns or leases property of a nature, or transacts business of a
     type, that would make such qualification necessary, except to the extent
     that the failure to so qualify or be in good standing would not have a
     material adverse effect

 
                                       4

     on the Company, the Guarantor and the Subsidiaries (as defined herein),
     considered as one enterprise.

     material adverse effect on the Company, the Guarantor and the Subsidiaries,
     considered as one enterprise.

          (viii)  The Guarantor's only direct subsidiary is the Company.  The

     Each Subsidiary is a corporation or limited partnership, as applicable,
     duly organized, validly existing and in good standing under the laws of the
     jurisdiction of its incorporation with corporate power and authority under
     such laws to own, lease and operate its properties and conduct its
     business; and each Subsidiary is duly qualified to transact business as a
     foreign corporation and is in good standing in each other jurisdiction in
     which it owns or leases property of a nature, or transacts business of a

     the Company's ownership of capital stock of each Subsidiary.  The Company
     owns such capital stock of each such Subsidiary free and clear of any
     pledge, lien, security interest, charge, claim, equity or encumbrance of

     the Guarantor, will be substantially in the form heretofore delivered to

     and the Guarantor, enforceable against the Company and the Guarantor in
     accordance with its terms, except as enforcement thereof may be limited by
     bankruptcy, insolvency (including, without limitation, all laws relating to
     fraudulent conveyances or transfers), reorganization, moratorium or similar

     Registration Rights Agreement conforms in all material respects to the
     description thereof in the Offering Memorandum.

          (xiii)  All of the outstanding shares of capital stock of the Company
     have been duly authorized and validly issued and are fully paid and non-

     that are not described in the Offering Memorandum to which the Company, the
     Guarantor or any Subsidiary is a party or which affect any of their
     respective properties, including ordinary routine litigation incidental to
     the business of the Company, the Guarantor or any Subsidiary, would not
     have a material adverse effect on the condition (financial or otherwise),

     Guarantor and the Subsidiaries, considered as one enterprise.

          (xviii)  The Company, the Guarantor and the Subsidiaries each have

     are in full force and effect, and none of the Company, the Guarantor nor
     any Subsidiary has any notice of any material claim of any sort that has
     been asserted by anyone adverse to the rights of the Company, the Guarantor
     or any Subsidiary  under any of the leases or subleases mentioned above, or
     affecting or questioning the rights of such corporation to the continued

     possesses or has obtained all material governmental licenses, permits,
     certificates, consents, orders, approvals and other authorizations
     necessary to own or lease, as the case may be, and to operate its
     properties and to carry on its business as presently conducted, and none of
     the Company, the Guarantor nor any Subsidiary has received any notice of

     permits, certificates, consents, orders, approvals or authorizations.

          (xx)  The Company, the Guarantor and the Subsidiaries each owns or
     possesses, or can acquire on reasonable terms, adequate patents, patent
     licenses, trademarks, service marks and trade names necessary to carry on
     its business as presently conducted, and none of the Company, the Guarantor
     nor any Subsidiary has received any notice of infringement of or conflict
     with asserted rights of others with respect to any patents, patent
     licenses, trademarks, service marks or trade names that

 
                                       9

     in the aggregate, if the subject of an unfavorable decision, ruling or
     finding, could materially adversely affect the condition (financial or
     otherwise), earnings, business affairs or business prospects of the
     Company, the Guarantor and the Subsidiaries, considered as one enterprise.

          (xxi)  To the best knowledge of the Company, no labor problem exists

     Guarantor and the Subsidiaries, considered as one enterprise, and the
     Company is not aware of any existing or imminent labor disturbance by the
     employees of any of its or the Subsidiaries' principal suppliers,
     contractors or customers that could reasonably be expected to materially
     adversely affect the condition (financial or otherwise), earnings, business
     affairs or business prospects of the Company, the Guarantor and the
     Subsidiaries, considered as one enterprise.

          (xxii)  The Company has not taken and will not take, directly or
     indirectly, any action designed to, or that might reasonably be expected
     to, cause or result in stabilization or manipulation of the price of the
     Securities.

     the Guarantor and the Subsidiaries required by law to be filed have been
     filed and all taxes shown by such returns or otherwise assessed, which are
     due and payable, have been paid, except assessments against which appeals
     have been or will be promptly taken and as to which adequate reserves have

     no assessment in connection therewith has been made against the Company.
     The Company, the Guarantor and the Subsidiaries each has filed all other
     tax returns that are required to have been filed by it pursuant to
     applicable foreign, state, local or other law except insofar as the failure
     to file such returns would not have a material adverse effect on the
     condition (financial or otherwise), earnings, business affairs or business
     prospects of the Company, the Guarantor and the Subsidiaries, considered as
     one enterprise, and has paid all taxes due pursuant to such returns or
     pursuant to any assessment received by the Company, the Guarantor and the
     Subsidiaries, except for such taxes, if any, as are being contested in good
     faith and as to which adequate reserves have been provided.  The charges,
     accruals and reserves on the books of the Company in respect of any income
     and corporation tax liability for any years not finally determined are
     adequate to meet any assessments or re-assessments for additional income
     tax for any years not finally determined, except to the extent of any
     inadequacy that would not have a material adverse effect on the condition
     (financial or otherwise), earnings, business affairs or business prospects
     of the Company, the Guarantor and the Subsidiaries, considered as one
     enterprise.

     assurances that (A) transactions are executed in accordance with

     recorded as necessary to permit preparation of financial statements in

with the Initial Purchaser as follows:

          (a) to furnish the Initial Purchaser with copies of the Offering
Memorandum in such quantities as the Initial Purchaser may from time to time
reasonably request, and if at any time prior to the completion of the sale of
the Securities by the Initial Purchaser to third parties any event shall have
occurred as a result of which the Offering Memorandum as then amended or
supplemented would include an untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made when such Offering
Memorandum is delivered, not misleading, to promptly inform the Initial
Purchaser and prepare and furnish without charge to the Initial Purchaser and to
any dealer in securities as many copies as the Initial Purchaser may from time

the Offering Memorandum which will correct such statement or omission or effect

under the securities laws of such jurisdictions as the Initial Purchaser may
request and to comply with such laws so as to permit the continuance of sales
and dealings therein in such jurisdictions for as long as may be necessary to
complete the placement of the Securities, provided that in connection therewith
                                          --------

such reports and information, together with such other documents, reports and
information as shall be furnished by the Company to the holders of the
Securities issued by it;

          (g) each Security will bear the following legend until, in the opinion

          execution and delivery thereof by each of the other parties thereto,

          Securities by the Company, the Securities, when duly authenticated by
          the Trustee in accordance with the terms of the Indenture and duly
          delivered against receipt of payment therefor in accordance with the

          and subject to the qualification that such counsel expresses no
          opinion as to the effect on the Securities of the laws of any
          jurisdiction other than federal law and the laws of the States of New
          York and Texas wherein any purchaser of the Securities may be located
          or wherein enforcement may be sought which limits the rate of interest
          legally chargeable or collectible.

          and the consummation by the Company and the Guarantor of the

          writ, injunction, decree, order or ruling of any court or government
          authority binding on the Company, the Guarantor or any Subsidiary of
          which such counsel is aware or (b) result in the creation of any lien
          on any of the material assets or properties of the Company, the
          Guarantor or any Subsidiary pursuant to any material agreement to
          which the Company, the Guarantor or any Subsidiary is a party of which
          we are aware.

               (vi)   The Indenture, the Securities, the Registration Rights
          Agreement, the Credit Agreement, dated as of March 30, 1995, among the
          Company, the Guarantor, The Chase Manhattan Bank (National
          Association), and the lenders party thereto, and Article Fourth of the
          Restated Certificate of Incorporation of the Guarantor, as amended to
          the date hereof, conform in all material respects to the descriptions
          thereof in the Offering Memorandum.

               (vii)  No consent, approval, waiver, license or authorization or
          other action by or filing with any New York, Delaware corporate or
          federal governmental authority is required in connection with the
          execution and delivery by the Company of the Securities or for the
          execution, delivery or performance of the Indenture by the Company and
          the Guarantor, except for federal and state securities or blue sky
          laws, as to which such counsel expresses no opinion in this paragraph
          (vii).

               (viii) Except as disclosed in the Offering Memorandum, to our
          knowledge, there is no litigation, proceeding or governmental
          investigation pending or overtly threatened against the Company or the
          Guarantor or any of the Subsidiaries that relates to any of the
          transactions contemplated by the Agreement, the Indenture, the
          Securities and the Registration Rights Agreement or which, if
          adversely determined, would have a material adverse effect on the
          business, assets or financial condition of the Guarantor, the Company
          and the Subsidiaries taken as a whole or on the ability of either the
          Guarantor or the Company to perform its respective obligations under
          the Agreement, the Indenture, the Securities and the Registration
          Rights

 
                                      20

          Agreement to which it is a party or to consummate the transactions
          contemplated by the Offering Memorandum.

               (ix) Such counsel has participated in conferences with officers
          and other representatives of the Guarantor and the Company and
          representatives of the independent public accountants for the
          Guarantor and the Company in connection with the preparation of the
          Offering Memorandum and although such counsel has not independently
          verified and is not passing upon and assumes no responsibility for the
          accuracy, completeness or fairness of the statements contained in the
          Offering Memorandum (except to the extent specified in the foregoing
          opinion) no facts have come to such counsel's attention which lead
          such counsel to believe that the Offering Memorandum, at any time from
          the date thereof through the Time of Delivery, contained any untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          contained therein, in light of the circumstances under which they were
          made, not misleading (it being understood that such counsel expresses
          no view with respect to the financial statements and related notes,
          the projections and the other financial, statistical and accounting
          data included in or appended as exhibits to the Offering Memorandum).

     Such opinion shall be to such further effect with respect to other legal
     matters relating to this Agreement and the sale of the Securities pursuant
     to this Agreement as counsel for the Initial Purchaser may reasonably
     request no less than two business days prior to the Time of Delivery.  Such
     counsel may also state that, insofar as such opinion involves factual
     matters, such counsel has relied, to the extent such counsel deems proper,
     upon certificates of officers of the Company, the Guarantor and the
     Subsidiaries and certificates of public officials; provided that copies of
     such certificates have been delivered to the Initial Purchaser.

          (b) At the Closing Time, you shall have received a signed opinion of
     Altheimer & Gray, local counsel for the Company and the Guarantor, dated as
     of the Closing Time, in form and substance satisfactory to counsel for the
     Initial Purchaser, to the effect that:

               (i) The Company is a corporation organized, validly existing, and
          in good standing under the laws of the State of Illinois with the
          corporate power and authority to own, lease and operate its properties
          and conduct its business as described in the Offering Memorandum.

               (ii) The Company is qualified to transact business as a foreign
          corporation in good standing in the states listed on Schedule 1
          thereto.

               (iii) All of the outstanding shares of stock of the Company are
          held by the Guarantor and have been duly authorized, validly issued,
          fully paid and non-assessable.

               (iv)  Each of the Indenture, the Securities, the Registration
          Rights Agreement and this Agreement have been duly authorized and
          executed by the Company.

               (v)   No authorization, approval, consent or license of any
          government or government instrumentality (other than under any
          securities or blue sky laws) is required for the valid authorization,
          issuance, sale and delivery of the Securities.

               (vi)  The execution and delivery of this Agreement, the Indenture
          and the Registration Rights Agreement by the Company, the issuance and
          delivery of the Securities, the consummation by the Company of the
          transactions contemplated thereby in the Offering Memorandum and
          compliance by the Company with the terms of this Agreement, the
          Indenture and the Registration Rights Agreement do not and will not
          result in any violation of the charter or by-laws of the Company.

          (c)  At the Closing Time, you shall have received the favorable
     opinion of Shearman & Sterling, counsel for the Initial Purchaser, dated as
     of the Closing Time, to the effect that the opinion delivered pursuant to
     Sections 5(a) appears on its face to be appropriately responsive to the
     requirements of this Agreement except, specifying the same, to the extent
     waived by you, and with respect to the incorporation and legal existence of
     the Company, the incorporation and legal existence of the Guarantor, the
     Securities, this Agreement, the Indenture, the Registration Rights
     Agreement, the Preliminary Offering Memorandum, the Offering Memorandum and
     such other related matters as you may require. In giving such opinion such
     counsel may rely, as to all matters governed by the laws of jurisdictions
     other than the law of the State of New York, the federal law of the United
     States and the General Corporation Law of the State of Delaware, upon the
     opinions of counsel satisfactory to you. Such counsel may also state that,
     insofar as such opinion involves factual matters, they have relied, to the
     extent they deem proper, upon certificates of officers of the Company, the
     Guarantor and the Subsidiaries and certificates of public officials;
     provided that such certificates have been delivered to the Initial
     Purchaser.

          (d)  At the Closing Time, (i) the Offering Memorandum, as it may then
     be amended or supplemented, shall not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, 
     (ii) there shall not have been, since the respective

 
                                      22

     dates as of which information is given in the Offering Memorandum, any
     material adverse change in the condition (financial or otherwise),
     earnings, business affairs or business prospects of the Company, the
     Guarantor and the Subsidiaries, considered as one enterprise, whether or
     not arising in the ordinary course of business, (iii) no action, suit or
     proceeding shall be  pending or, to the knowledge of the Company,
     threatened against the Company, the Guarantor or any Subsidiary that could

     condition (financial or otherwise), earnings, business affairs or business
     prospects of the Company, the Guarantor and the Subsidiaries, considered as
     one enterprise other than as set forth in the Offering Memorandum and no
     proceedings shall be pending or, to the knowledge of the Company,
     threatened against the Company, the Guarantor or any Subsidiary before or
     by any government, governmental instrumentality or court, domestic or
     foreign, that could reasonably be expected to result in any material
     adverse change in the condition (financial or otherwise), earnings,
     business affairs or business prospects of the Company, the Guarantor and
     the Subsidiaries, considered as one enterprise, other than as set forth in
     the Offering Memorandum, (iv) the Company and the Guarantor shall have
     complied with all agreements and satisfied all conditions on their
     respective parts to be performed or satisfied at or prior to the Closing
     Time, (v) no event of default shall exist under any contract, indenture,
     mortgage, loan agreement, note, lease or other agreement or instrument
     constituting Senior Indebtedness (as defined in the Indenture) and (vi) the
     other representations and warranties of the Company set forth in Section
     1(a) shall be accurate as though expressly made at and as of the Closing
     Time.  At the Closing Time, you shall have received a certificate of the
     President or a Vice President, and the Chief Financial Officer, Treasurer
     or Controller, of the Company and the Guarantor, dated as of the Closing
     Time, to such effect.

          (e) You shall have received on each of the date hereof and the Closing
     Date a letter, dated the date hereof or the Closing Date, as the case may
     be, in form and substance satisfactory to you, from Arthur Andersen LLP,
     the Company's independent public accountants, containing statements and
     information of the type ordinarily included in accountants "comfort
     letters" to underwriters with respect to the financial statements and

          (i) At the Closing Time, counsel for the Initial Purchaser shall have
     been furnished with all such documents, certificates and opinions as they
     may reasonably request for the purpose of enabling them to pass upon the
     issuance and sale of the Securities as contemplated in this Agreement and
     the matters referred to in Section 5(d) and in order to evidence the
     accuracy and completeness of any of the representations, warranties or
     statements of the Company, the performance of any of the covenants of the
     Company, or the fulfillment of any of the conditions herein contained; and
     all proceedings taken by the Company at or prior to the Closing Time in
     connection with the authorization, issuance and sale of the Securities as
     contemplated in this Agreement shall be reasonably satisfactory in form and

     Purchaser.

               Section 6.  Indemnification.  (a)  The Company and the Guarantor
                           ---------------
each agree jointly and severally to indemnify and hold harmless the Initial
Purchaser and each person, if any, who controls the Initial Purchaser within the
meaning of Section 15 of the 1933 Act as follows:

          (i)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of or based upon an untrue statement
     or alleged untrue statement of a material fact contained in the Preliminary
     Offering Memorandum or the Offering Memorandum (or any amendment or
     supplement thereto) or the omission or alleged omission therefrom of a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company or the Guarantor; and

          (iii) against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any

 
                                      24

     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------                                                           
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Initial Purchaser expressly for use in the Preliminary Offering Memorandum or
the Offering Memorandum (or any amendment or supplement thereto); and provided,
                                                                      -------- 
further, that the Company will not be liable to the Initial Purchaser or any
- -------                                                                     
person controlling the Initial Purchaser with respect to any such untrue
statement or omission made in any preliminary prospectus that is corrected in
the Prospectus (or any amendment or supplement thereto) if the person asserting
any such loss, claim, damage or liability purchased Securities from the Initial
Purchaser in reliance upon a preliminary prospectus but was not sent or given a
copy of the Prospectus (as amended or supplemented) at or prior to the written
confirmation of the sale of such Securities to such person in any case where
such delivery of the Prospectus (as so amended or supplemented) is required by
the 1933 Act, unless such failure to deliver the Prospectus (as amended or
supplemented) was a result of noncompliance by the Company with Section 3 of
this Agreement.

          (b) The Initial Purchaser agrees to indemnify and hold harmless the
Company and the Guarantor, and each person, if any, who controls the Company or
the Guarantor within the meaning of Section 15 of the 1933 Act, against any and
all loss, liability, claim, damage and expense described in the indemnity
agreement in Section (a), as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in any
preliminary offering memorandum or the Offering Memorandum (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by the Initial Purchaser expressly for use in such
preliminary offering memorandum or the Offering Memorandum (or any amendment or
supplement thereto).

          (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement.  An indemnifying party may participate
at its own expense in the defense of such action.  In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

          Section 7.  Contribution.  In order to provide for just and equitable
                      ------------                                             
contribution in circumstances under which the indemnity provided for in Section
6 is for any

 
                                      25

reason held to be unenforceable by the indemnified parties although applicable
in accordance with its terms, the Company and the Guarantor on the one hand and
the Initial Purchaser on the other shall contribute to the aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity incurred by the Company and the Initial Purchaser, as incurred, in
such proportions that the Initial Purchaser is responsible for that portion
represented by the percentage that the Initial Purchaser's discount appearing on
the cover page of the Offering Memorandum bears to the price to investors
appearing thereon, and the Company and the Guarantor are responsible for the
balance; provided, however, that no person guilty of fraudulent
         --------  -------                                     
misrepresentation (within the meaning of Section 1(f) of the 1933 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section, each person, if any, who
controls the Initial Purchaser within the meaning of Section 5 of the 1933 Act
shall have the same rights to contribution as the Initial Purchaser, and each
person, if any, who controls the Company or the Guarantor within the meaning of
Section 5 of the 1933 Act shall have the same rights to contribution as the
Company and the Guarantor.

          Section 8.  Representations, Warranties and Agreements to Survive
                      -----------------------------------------------------
Delivery.  The representations, warranties, indemnities, agreements and other
- --------                                                                     
statements of the Company, the Guarantor, the Initial Purchaser, or their
respective officers set forth in or made pursuant to this Agreement will remain
operative and in full force and effect regardless of any investigation made by
or on behalf of the Company, the Guarantor, the Initial Purchaser or any person
who controls the Company, the Guarantor or the Initial Purchaser within the
meaning of Section 5 of the 1933 Act and will survive delivery of and payment
for the Securities.

          Section 9.  Termination of Agreement.  (a)  The Initial Purchaser may
                      ------------------------                                 
terminate this Agreement, by notice to the Company, at any time at or prior to
the Closing Time (i) if there has been, since the respective dates as of which
information is given in the Offering Memorandum, any material adverse change in
the condition (financial or otherwise), earnings, business affairs or business
prospects of the Company, the Guarantor and the Subsidiaries, considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
if there has occurred any material adverse  change in the financial markets in
the United States or any outbreak of hostilities or escalation thereof or other
calamity or crisis the effect of which on the financial markets of the United
States is such as to make it, in the Initial Purchaser's judgment, impracticable
to market the Securities or enforce contracts for the sale of the Securities or
(iii) if trading in any securities of the Company or the Guarantor has been
suspended by the Commission or the National Association of Securities Dealers,
Inc., or if trading generally on either the American Stock Exchange or the New
York Stock Exchange or in the over-the-counter market has been suspended, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices for securities have been required, by such exchange or by order of the
Commission, the National Association of Securities Dealers, Inc. or any other
governmental authority or (iv) if a banking moratorium has been declared by
either federal, New York or Illinois authorities.

 
                                      26

          (b) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party, except
to the extent provided in Section 4.  Notwithstanding any such termination, the
provisions of Sections 6, 7 and 8 shall remain in effect.

          Section 10.  Notices.  All statements, requests, notices, and
                       -------

expressed, any person who controls the Company, the Guarantor or the Initial
Purchaser within the meaning of Section 15 of the 1933 Act, and their respective

acquire or have any right under or by virtue of this Agreement.  The term

more counterparts and when a counterpart has been executed by each party, all
such counterparts taken together shall constitute one and the same agreement.

- ------------                                                                   
interpretation of the Staff of the SEC, the Company shall use its best efforts
(i) to file within 30 days after the Closing Date an Exchange Offer Registration
Statement covering the offer by the Company to the Holders to exchange all of
the Registrable Securities for Exchange Securities, (ii) to cause such Exchange
Offer Registration Statement to be declared effective by the SEC within 120 days
after the Closing Date, (iii) to cause such Registration Statement to remain
effective until the closing of the Exchange Offer and (iv) to consummate the
Exchange Offer within 150 days following the Closing Date.  The Exchange
Securities will be issued under the Indenture.  Upon the effectiveness of the
Exchange Offer Registration Statement, the Company shall promptly commence the
Exchange Offer, it being the objective of such Exchange Offer to enable each
Holder (other than Participating Broker-Dealers (as defined in Section 3(f)
hereof) eligible and electing to exchange Registrable Securities for Exchange
Securities (assuming that such Holder is not an affiliate of the Company within
the meaning of Rule 405 under the 1933 Act, acquires the Exchange Securities in
the ordinary course of such Holder's business and has no arrangements or
understandings with any person to participate in the Exchange Offer for the
purpose of distributing the Exchange Securities) to trade such Exchange
Securities from and after their receipt without any limitations or restrictions
under the 1933 Act.

          In connection with the Exchange Offer, the Company shall:

          (i)   mail to each Holder, at its address reflected on the security
     register, a copy of the Prospectus forming part of the Exchange Offer
     Registration Statement, together with an appropriate letter of transmittal
     (a "Letter of Transmittal") and related documents;

          (ii)  keep the Exchange Offer open for not less than 30 calendar days
     after the date notice thereof is mailed to the Holders (or longer if
     required by applicable law);

          (iii) permit Holders to withdraw tendered Registrable Securities at
     any time prior to the close of business, New York City time, on the last
     business day on which

 
                                      5 

     the Exchange Offer shall remain open, by sending to the institution
     specified in the notice, a telegram, telex, facsimile transmission or
     letter setting forth the name of such Holder, the principal amount of
     Registrable Securities delivered for exchange, and a statement that such
     Holder is withdrawing his election to have such Securities exchanged; and

          (iv)   otherwise comply in all respects with all applicable laws
     relating to the Exchange Offer.

          As soon as practicable after the close of the Exchange Offer, the
Company shall:

          (i)    accept for exchange Registrable Securities duly tendered and
     not validly withdrawn pursuant to the Exchange Offer in accordance with the
     terms of the Exchange Offer Registration Statement and the Letter of
     Transmittal;

          (ii)   deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities so accepted for exchange by the
     Company; and

          (iii)  cause the Trustee promptly to authenticate and deliver Exchange
     Securities to, or upon the instructions of, each Holder of Registrable
     Securities equal in principal amount to the Registrable Securities of such
     Holder so accepted for exchange.

          Interest on each Exchange Security will accrue from the last date on
which interest was paid on the Registrable Securities surrendered in exchange
therefor or, if no interest has been paid on the Registrable Securities, from
the date of its original issue.  The Exchange Offer shall not be subject to any
conditions, other than that the Exchange Offer, or the making of any exchange by
a Holder, does not violate applicable law or any applicable interpretation of
the Staff of the SEC.  Each Holder of Registrable Securities (other than
Participating Broker-Dealers) who wishes to exchange such Registrable Securities
for Exchange Securities in the Exchange Offer will be required to represent that
(i) it is not an affiliate of United or the Company, (ii) any Exchange
Securities to be received by it were acquired in the ordinary course of its
business and (iii) at the time of the commencement of the Exchange Offer, it has
no arrangement with any person to participate in the distribution (within the
meaning of the 1933 Act) of the Exchange Securities.  The Company shall inform
the Initial Purchaser of the names and addresses of the Holders to whom the
Exchange Offer is made, and the Initial Purchaser shall have the right to
contact such Holders and otherwise facilitate the tender of Registrable
Securities in the Exchange Offer.

          (b) Shelf Registration.  (i) If, because of any change in law or
              ------------------                                          
applicable interpretations thereof by the Staff of the SEC, the Company is not
permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof,
(ii) upon the request of the Initial Purchaser (with respect to any Registrable
Securities which it acquired directly from the Company) within 30 calendar days
after the Closing Date if the Initial Purchaser shall hold Registrable
Securities which it acquired directly from the Company and if the Initial
Purchaser is not permitted, in the opinion of counsel to the Initial Purchaser
addressed to the

 
                                       6

Company (which counsel shall be reasonably acceptable to the Company), pursuant
to applicable law or applicable interpretation of the Staff of the SEC to
participate in the Exchange Offer, or (iii) if any Holder other than the Initial
Purchaser is not eligible to participate in the exchange offer due to a change
in law or the applicable interpretation of the staff of the Commission and such
holder so notifies the Company, the Company shall, at its cost,

          (A) as promptly as practicable, file with the SEC a Shelf Registration
     Statement relating to the offer and sale of the Registrable Securities
     (limited solely to the Initial Purchaser if clause (ii) alone applies) by
     the Holders from time to time in accordance with the methods of
     distribution elected by the Majority Holders of such Registrable Securities
     and set forth in such Shelf Registration Statement, and use its best
     efforts to cause such Shelf Registration Statement to be declared effective
     by the SEC by the later of (1) 120 days after the Closing Date and (2) 45
     days after publication of the change in law or interpretation.  In the
     event that the Company is required to file a Shelf Registration Statement
     upon the request of the Initial Purchaser pursuant to clause (ii) above,
     the Company shall file and have declared effective by the SEC both an
     Exchange Offer Registration Statement pursuant to Section 2(a) hereof with
     respect to all Registrable Securities and a Shelf Registration Statement
     (which may be a combined Registration Statement with the Exchange Offer
     Registration Statement) with respect to offers and sales of Registrable
     Securities held by the Initial Purchaser after completion of the Exchange
     Offer;

          (B) use its best efforts to keep the Shelf Registration Statement
     continuously effective in order to permit the Prospectus forming part
     thereof to be usable by Holders for a period of (i), in the case of clause
     2(b)(i) above, three years from the date the Shelf Registration Statement
     is declared effective by the SEC, or (ii) in the case of clauses 2(b)(ii)
     and 2(b)(iii) above, three years after the closing date, or in any case
     such shorter period which will terminate when all of the Registrable
     Securities covered by the Shelf Registration Statement have been sold
     pursuant to the Shelf Registration Statement or cease to be outstanding;
     and

          (C) notwithstanding any other provisions hereof, use its best efforts
     to ensure that (i) any Shelf Registration Statement complies in all
     material respects with the 1933 Act and the rules and regulations
     thereunder, (ii) any Shelf Registration Statement does not, when it becomes
     effective, contain an untrue statement of a material fact or omit to state
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading and (iii) any Prospectus forming part of
     any Shelf Registration Statement, and any supplement to such Prospectus (as
     amended or supplemented from time to time), does not include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements, in light of the circumstances under which
     they were made, not misleading.

          The Company further agrees, if necessary, to supplement or amend the
Shelf Registration Statement if reasonably requested by the Majority Holders
with respect to information relating to the Holders and otherwise as required by
Section 3(b) below, to use all reasonable efforts to cause any such amendment to
become effective and such Shelf

 
                                       7

Registration to become usable as soon as thereafter practicable and to furnish
to the Holders of Registrable Securities copies of any such supplement or
amendment promptly after its being used or filed with the SEC.

          (c) Expenses.  The Company shall pay all Registration Expenses in
              --------                                                     
connection with the registration pursuant to Section 2(a) or 2(b).

          (d) Effective Registration Statement.  An Exchange Offer Registration
              --------------------------------                                 
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the SEC; provided, however, that if,
                                                  --------  -------          
after it has been declared effective, the offering of Registrable Securities
pursuant to a Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Registration Statement will be deemed not to have been
effective during the period of such interference, until the offering of
Registrable Securities pursuant to such Registration Statement may legally
resume.

          (e) Increase in Interest Rate.  In the event that (i) the Exchange
              -------------------------                                     
Offer Registration Statement is not filed with the SEC on or prior to the 30th
calendar day after the Closing Date (unless changes in law or the applicable
interpretation of the staff of the Commission do not permit the Company to
effect the Exchange Offer, in which case clause (iv) shall apply), (ii) the
Exchange Offer Registration Statement is not initially declared effective on or
prior to the 120th calendar day after the Closing Date (unless changes in law or
the applicable interpretation of the staff of the Commission do not permit the
Company to effect the Exchange Offer, in which case clause (iv) shall apply) or
(iii) the Exchange Offer is not consummated on or prior to the 150th day after
the Closing Date (unless changes in law or the applicable interpretation of the
staff of the Commission do not permit the Company to effect the Exchange Offer,
in which case clause (iv) shall apply) or (iv) a Shelf Registration Statement
required under Section 2(b)(i) hereof with respect to the Registrable Securities
is not initially declared effective on or prior to the later of 120th calendar
day after the Closing Date or the 45th calendar day after the publication of the
change in law or interpretation, the interest rate borne by the Securities shall
be increased by one-half of one percent per annum following such 30-day period
in the case of clause (i) above, such 120-day period in the case of clause (ii)
above, such 150-day period in the case of clause (iii) above or such 120-day or
45-day period in the case of clause (iv) above (as applicable); provided that
                                                                --------     
the aggregate increase in such interest rate will in no event exceed one-half of
one percent per annum.  Immediately upon (A) the filing of the Exchange Offer
Registration Statement after the 30-day period described in clause (i) above,
(B) the effectiveness of the Exchange Offer Registration Statement after the
120-day period described in clause (ii) above, (C) the consummation of the
Exchange Offer after the 150-day period described in clause (iii) above or (D)
the effectiveness of a Shelf Registration Statement after such 120-day or 45-day
period described in clause (iv) above (as applicable), the interest rate borne
by the Securities from the date of such filing, effectiveness or consummation,
as the case may be, will be reduced to the original interest rate.

          (f) Specific Enforcement.  Without limiting the remedies available to
              --------------------                                             
the Initial Purchaser and the Holders, the Company acknowledges that any failure
by the

 
                                       8

Company to comply with its obligations under Section 2(a) and Sections 2(b)
hereof may result in material irreparable injury to the Initial Purchaser or the
Holders for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchaser or any Holder may obtain such relief
as may be required to specifically enforce the Company's obligations under
Section 2(a) and Section 2(b) hereof.

          (g) Acknowledgment of Holders.  Each Holder shall be deemed to have
              -------------------------                                      
agreed that any broker-dealer and any such Holder using the Exchange Offer to
participate in a distribution of the securities to be acquired in the Exchange
Offer must comply with the registration and prospectus delivery requirements of
the 1933 Act in connection with secondary resale transactions and that such
secondary resale transactions should be covered by an effective registration
statement.

          3.   Registration Procedures.   In connection with the obligations of
               -----------------------

or incorporate by reference all financial statements required by the SEC to be
filed therewith, and use its best efforts to cause such Registration Statement
to become effective and remain effective in accordance with Section 2 hereof;

          (b) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary under applicable

and as so supplemented to be filed if required pursuant to Rule 424 under the
1933 Act; comply with the provisions of the 1933 Act with respect to the
disposition of all securities covered by each Registration Statement during the
applicable period in accordance with the intended method or methods of

during the period described under Section 4(3) and Rule 174 under the 1933 Act
that is applicable to transactions by brokers or dealers with respect to
Exchange Securities or Registrable Securities;

          (c) in the case of a Shelf Registration, (i) notify each Holder of
Registrable Securities, at least five days prior to filing, that a Shelf

supplement thereto and such other

 
                                       9

documents as such Holder or underwriter may reasonably request, including
financial statements and schedules and, if the Holder so requests, all exhibits
(including those incorporated by reference) in order to facilitate the public
sale or other disposition of the Registrable Securities; and (iii) subject to
the last paragraph of Section 3 hereof, hereby consent to the use of the
Prospectus or any amendment or supplement thereto by each of the selling Holders
of Registrable Securities in connection with the offering and sale in accordance
with applicable law of the Registrable Securities covered by the Prospectus or
any amendment or supplement thereto;

          (d) use its best efforts to register or qualify the Registrable
Securities under all applicable state securities or "blue sky" laws of such
jurisdictions as any Holder of Registrable Securities covered by a Registration
Statement and each underwriter of an underwritten offering of Registrable
Securities shall reasonably request in writing by the time the applicable
Registration Statement is declared effective by the SEC, to cooperate with the
Holders in connection with any filings required to be made with the NASD, and do
any and all other acts and things which may be reasonably necessary or advisable
to enable such Holder to consummate the disposition in each such jurisdiction of
such Registrable Securities owned by such Holder; provided, however, that the
                                                  --------  -------          
Company shall not be required to (i) qualify as a foreign corporation or as a
dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d) or (ii) take any action which
would subject it to general service of process or taxation in any such
jurisdiction if it is not then so subject;

          (e) in the case of a Shelf Registration, notify each Holder of
Registrable Securities and counsel for the Initial Purchaser promptly and, if
requested by such Holder or counsel, confirm such advice in writing promptly (i)
when a Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of any request by the
SEC or any state securities authority for post-effective amendments and
supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (iii) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation of
any proceedings for that purpose, (iv) if, between the effective date of a
Registration Statement and the closing of any sale of Registrable Securities
covered thereby, the representations and warranties of the Company contained in
any underwriting agreement, securities sales agreement or other similar
agreement, if any, relating to such offering cease to be true and correct in all
material respects, (v) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose, (vi) of the happening of any event or the discovery of any facts
during the period a Shelf Registration Statement is effective which makes any
statement made in such Registration Statement or the related Prospectus untrue
in any material respect or which requires the making of any changes in such
Registration Statement or Prospectus in order to make the statements therein not
misleading and (vii) of any determination by the Company that a post-effective
amendment to a Registration Statement would be appropriate;

          (f) a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a

 
                                      10

Prospectus or any document which is to be incorporated by reference into a
Registration Statement or a Prospectus after initial filing of a Registration
Statement, provide copies of such document to the Initial Purchaser and its
counsel (and, in the case of a Shelf Registration Statement, the Holders and
their counsel) and make representatives of the Company as shall be reasonably
requested by the Initial Purchaser and their counsel (and, in the case of a
Shelf Registration Statement, the Holders or their counsel) available for
discussion of such document and shall not at any time file or make any amendment
to the Registration Statement, any Prospectus or any amendment of or supplement
to a Registration Statement or a Prospectus or any document which is to be
incorporated by reference into a Registration Statement or a Prospectus, of
which the Initial Purchaser and its counsel (and, in the case of a Shelf
Registration Statement, the Holders and their counsel) shall not have previously
been advised and furnished a copy or to which the Initial Purchaser or its
counsel (and, in the case of a Shelf Registration Statement, the Holders or
their counsel) shall reasonably object unless counsel for the Company advises
the Company that such filing by the Company is required under applicable law;

          (g) (i) in the case of an Exchange Offer, furnish counsel for the
Initial Purchaser and (ii) in the case of a Shelf Registration, furnish counsel
for the Holders of Registrable Securities copies of any request by the SEC or
any state securities authority for amendments or supplements to a Registration
Statement and Prospectus or for additional information;

          (h) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement as soon as practicable
and provide immediate notice to each Holder of the withdrawal of any such order;

          (i) in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities, without charge, at least one conformed copy of each
Registration Statement and any post-effective amendment thereto (without
documents incorporated therein by reference or exhibits thereto, unless
requested);

          (j) in the case of a Shelf Registration, cooperate with the selling
Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends; and cause such Registrable Securities to be in
such denominations (consistent with the provisions of the Indenture) and
registered in such names as the selling Holders or the underwriters, if any, may
reasonably request at least two business days prior to the closing of any sale
of Registrable Securities;

          (k) in the case of a Shelf Registration, upon the occurrence of any
event or the discovery of any facts, each as contemplated by Section 3(e)(vi)
hereof, use its best efforts to prepare a supplement or post-effective amendment
to a Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Securities, such
Prospectus will not contain at the time of such delivery any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  The Company

 
                                      11

agrees to notify each Holder to suspend use of the Prospectus as promptly as
practicable after the occurrence of such an event, and each Holder hereby agrees
to suspend use of the Prospectus until the Company has amended or supplemented
the Prospectus to correct such misstatement or omission.  At such time as such
public disclosure is otherwise made or the Company determines that such
disclosure is not necessary, in each case to correct any misstatement of a
material fact or to include any omitted material fact, the Company agrees
promptly to notify each Holder of such determination and to furnish each Holder
such numbers of copies of the Prospectus, as amended or supplemented, as such
Holder may reasonably request;

          (l) obtain a CUSIP number for all Exchange Securities, or Registrable
Securities, as the case may be, not later than the effective date of a
Registration Statement, and provide the Trustee with printed certificates for
the Exchange Securities or the Registrable Securities, as the case may be, in a
form eligible for deposit with the Depositary;

          (m) (i) cause the Indenture to be qualified under the Trust Indenture
Act of 1939, as amended (the "TIA"), in connection with the registration of the
Exchange Securities, or Registrable Securities, as the case may be, 
(ii) cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the TIA and (iii) execute, and use its best efforts to cause
the Trustee to execute, all documents as may be required to effect such changes,
and all other forms and documents required to be filed with the SEC to enable
the Indenture to be so qualified in a timely manner;

          (n) in the case of a Shelf Registration, enter into agreements
(including customary underwriting agreements) and take all other customary and
appropriate actions (including those reasonably requested by the Majority
Holders) in order to expedite or facilitate the disposition of such Registrable
Securities and in such connection whether or not an underwriting agreement is
entered into and whether or not the registration is an underwritten
registration:

          (i)   to the extent possible, make such representations and warranties
     to the Holders of such Registrable Securities and the underwriters, if any,
     in form, substance and scope as are customarily made by issuers to
     underwriters in similar underwritten offerings as may be reasonably
     requested by them;

          (ii)  obtain opinions of counsel to the Company and, subject to the
     proviso in the first sentence of the last paragraph of this clause (n),
     updates thereof (which counsel and opinions (in form, scope and substance)
     shall be reasonably satisfactory to the managing underwriters, if any, and
     the Majority Holders of the Registrable Securities being sold) addressed to
     each selling Holder and the underwriters, if any, covering the matters
     customarily covered in opinions requested in sales of securities or
     underwritten offerings and such other matters as may be reasonably
     requested by such Holders and underwriters;

          (iii) obtain "cold comfort" letters and, subject to the proviso in
     the first sentence of the last paragraph of this clause (n), updates
     thereof from the Company's

 
                                      12

     independent certified public accountants addressed to the underwriters, if
     any, and use reasonable best efforts to have such letter addressed to the
     selling Holders of Registrable Securities, such letters to be in customary
     form and covering matters of the type customarily covered in "cold comfort"
     letters to underwriters in connection with similar underwritten offerings;

          (iv) enter into a securities sales agreement with the Holders and an
     agent of the Holders providing for, among other things, the appointment of
     such agent for the selling Holders for the purpose of soliciting purchases
     of Registrable Securities, which agreement shall be in form, substance and
     scope customary for similar offerings;

          (v)  if an underwriting agreement is entered into, cause the same to
     set forth indemnification provisions and procedures substantially
     equivalent to the indemnification provisions and procedures set forth in
     Section 6 hereof with respect to the underwriters and all other parties to
     be indemnified pursuant to said Section; and

          (vi) deliver such other documents and certificates as may be
     reasonably requested and as are customarily delivered in similar offerings.

The above shall be done at (i) the effectiveness of such Registration Statement
(and, if appropriate, each post-effective amendment thereto) and (ii) each
closing under any underwriting or similar agreement as and to the extent
required thereunder; provided that the updates referred to in clauses (ii) and
                     --------                                                 
(iii) of this paragraph (n) shall only be required in the case of (A) any
closing with respect to sales under such Shelf Registration Statement of
Securities having a principal amount of $7.5 million or more or, if the Initial
Purchaser shall waive such updates under clause (A), then (B) in the case of up
to three such closings.  In the case of any underwritten offering, the Company
shall provide written notice to the Holders of all Registrable Securities of
such underwritten offering at least 30 days prior to the filing of a prospectus
supplement for such underwritten offering.  Such notice shall (x) offer each
such Holder the right to participate in such underwritten offering, (y) specify
a date, which shall be no earlier than 10 days following the date of such
notice, by which such Holder must inform the Company of its intent to
participate in such underwritten offering and (z) include the instructions such
Holder must follow in order to participate in such underwritten offering;

          (o) in the case of a Shelf Registration, make available for inspection
by one representative appointed by the Majority Holders of the Registrable
Securities and any underwriters participating in any disposition pursuant to a
Shelf Registration Statement and one counsel or accountant retained by such
Holders or underwriters, all financial and other records, pertinent corporate
documents and properties of the Company reasonably requested by any such
persons, and cause the respective officers, directors, employees, and any other
agents of the Company to supply all information reasonably requested by any such
representative, underwriter, special counsel or accountant in connection with a
Registration Statement; provided, however, that any records, information or
                        --------  -------                                  
documents that are designated by the Company as confidential at the time of
delivery of such records, information or documents shall be kept confidential by
such persons, unless (i) such records, information or documents are in the
public domain or otherwise publicly available;

 
                                      13

(ii) disclosure of such records, information or documents is required by court
or administrative order, provided that such person will, promptly upon learning
that disclosure of such information is sought in a court of competent
jurisdiction, give notice to the Company so that the Company may at its expense
undertake appropriate action to prevent disclosure of the information deemed to
be confidential, (iii) disclosure of such records, information or documents, in
the opinion of counsel to such person, is otherwise required by law (including,
without limitation, pursuant to the requirements of the 1933 Act) or (iv) upon
the advice of counsel, disclosure of such records, information or documents is
necessary to avoid or correct a misstatement or omission in the Registration
Statement;

          (p) in the case of a Shelf Registration, use its best efforts to cause
all Registrable Securities to be listed on any securities exchange on which
similar debt securities issued by the Company are then listed if requested in
writing by the Majority Holders or by the underwriter or underwriters of an
underwritten offering of Registrable Securities, if any;

          (q) in the case of a Shelf Registration, use its best efforts to cause
the Registrable Securities to be rated with the appropriate rating agencies, if
so requested by the Majority Holders or by the underwriter or underwriters of an
underwritten offering of Registrable Securities, if any, unless the Registrable
Securities are already so rated;

          (r) otherwise use its best efforts to comply with all applicable rules
and regulations of the SEC and make available to its security holders, as soon
as reasonably practicable, an earnings statement covering at least 12 months
which shall satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158
thereunder; and

          (s) cooperate and assist in any filings required to be made with the
NASD and in the performance of any due diligence investigation by any
underwriter and its counsel.

          In the case of a Shelf Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Company such information
regarding such Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
or the discovery of any facts, each of the kind described in 
Section 3(e)(ii)-(vi) hereof, such Holder will forthwith discontinue disposition
of Registrable Securities pursuant to a Registration Statement until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(k) hereof, and, if so directed by the Company, such
Holder will deliver to the Company (at its expense) all copies in its possession
or certify in writing that such copies have been destroyed, in each case other
than permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice to suspend the disposition of
Registrable Securities pursuant to a Shelf Registration Statement as a result of
the happening of any event or the discovery of any facts, each of the kind
described in Section 3(e)(vi) hereof, the Company shall be deemed to have used
its best

 
                                      14

efforts to keep the Shelf Registration Statement effective during such period of
suspension provided that the Company shall use its best efforts to file and have
declared effective (if an amendment) as soon as practicable an amendment or
supplement to the Shelf Registration Statement and shall extend the period
during which the Registration Statement shall be maintained effective pursuant
to this Agreement by the number of days during the period from and including the
date of the giving of such notice to and including the date when the Holders
shall have received copies of the supplemented or amended Prospectus necessary
to resume such dispositions.

          4.   Underwritten Registrations.  If any of the Registrable Securities
               --------------------------                                       
covered by any Shelf Registration are to be sold in an underwritten offering as
contemplated by Section 3 hereof, the investment banker or investment bankers
and manager or managers (and their counsel) that will manage the offering will
be agreed to by the Company and the Majority Holders of such Registrable
Securities included in such offering.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (b) completes, executes and delivers all questionnaires, powers
of attorney, indemnities, underwriting agreements and other documents required
of such Holder under the terms of such underwriting arrangements.

          5.   Participation of Broker-Dealers in Exchange Offer
               -------------------------------------------------

          (a) The Staff of the SEC has taken the position that any broker-dealer
that receives Exchange Securities for its own account in the Exchange Offer in
exchange for Registrable Securities that were acquired by such broker-dealer as
a result of market-making or other trading activities (a "Participating Broker-
Dealer") may be deemed to be an "underwriter" within the meaning of the 1933 Act
in connection with any resale of such Exchange Notes.

          The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Securities owned by
them, such Prospectus may be delivered by Participating Broker-Dealers to
satisfy their prospectus delivery obligations under the 1933 Act in connection
with resales of Exchange Securities for their own accounts, so long as the
Prospectus otherwise meets the requirements of the 1933 Act.

          (b) In light of the above, notwithstanding any other provision of this
Agreement, the Company agrees (x) that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such modifications thereto as may be,
reasonably requested by the Initial Purchaser or one or more Participating
Broker-Dealers, in each case as provided in clause (ii) below, in order to
expedite or facilitate the disposition of any Exchange Securities by
Participating Broker-Dealers consistent with the positions of the Staff recited
in Section 5(a) above and (y) without limiting the preceding clause (x), to
maintain the effectiveness of the Registration Statement

 
                                      15

for such purposes for the earlier of one year or until such Participating Broker
Dealers have sold all Exchange Securities (as determined in accordance with FIFO
accounting), but in any event only if applicable interpretations of the Staff
continue to require Prospectus delivery; provided that:
                                         --------      

          (i)  the Company shall not be required to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 3(k), for a period exceeding 180 days
     after the last Exchange Date (as such period may be extended pursuant to
     the last paragraph of Section 3 of this Agreement) and Participating
     Broker-Dealers shall not be authorized by the Company to deliver and shall
     not deliver such Prospectus after such period in connection with the
     resales contemplated by this Section 5; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Company by the Initial Purchaser or with the
     reasonable request in writing to the Company by one or more broker-dealers
     who certify to the Initial Purchaser and the Company in writing that they
     anticipate that they will be Participating Broker-Dealers; and provided
                                                                    --------
     further that, in connection with such application of the Shelf Registration
     -------                                                                    
     procedures set forth in Section 3 to an Exchange Offer Registration, the
     Company shall be obligated (x) to deal only with one entity representing
     the Participating Broker-Dealers, which shall be the Initial Purchaser
     unless it elects not to act as such representative, (y) to pay the fees and
     expenses of only one counsel representing the Participating Broker-Dealers,
     which shall be counsel to the Initial Purchaser unless such counsel elects
     not to so act and (z) to cause to be delivered only one, if any, "cold
     comfort" letter with respect to the Prospectus in the form existing on the
     last Exchange Date and with respect to each subsequent amendment or
     supplement, if any, effected during the period specified in clause (i)
     above.

          (c) The Initial Purchaser shall have no liability to the Company or
any Holder with respect to any request that it may make pursuant to this Section
5.

          Section 6.  Indemnification.  (a)  The Company and United each agree
                      ---------------                                         
jointly and severally to indemnify and hold harmless the Initial Purchaser, each
Holder, including Participating Broker Dealers, each underwriter who
participated in an offering of the Registrable Securities and each person, if
any, who controls such parties within the meaning of Section 15 of the 1933 Act
as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto) or the omission or alleged omission therefrom of
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading or arising out of an untrue statement or
     alleged untrue statement of a material fact included in any preliminary
     prospectus or the Prospectus (or any amendment or supplement thereto)

 
                                      16

     or the omission or alleged omission therefrom of a material fact necessary
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------                                                           
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company or
United by the Initial Purchaser expressly for use in the Registration Statement
(or any amendment thereto) or any preliminary prospectus or the Prospectus (or
any amendment or supplement thereto); and provided, further, that the Company
                                          --------  -------                  
will not be liable to the Initial Purchaser or any person controlling the
Initial Purchaser with respect to any such untrue statement or omission made in
any preliminary prospectus that is corrected in the Prospectus (or any amendment
or supplement thereto) if the person asserting any such loss, claim, damage or
liability purchased Securities from the Initial Purchaser in reliance upon a
preliminary prospectus but was not sent or given a copy of the Prospectus (as
amended or supplemented) at or prior to the written confirmation of the sale of
such Securities to such person in any case where such delivery of the Prospectus
(as so amended or supplemented) is required by the 1933 Act, unless such failure
to deliver the Prospectus (as amended or supplemented) was a result of
noncompliance by the Company with Section 3 of this Agreement.

          (b) The Initial Purchaser agrees to indemnify and hold harmless each
of the Company, United and each person, if any, who controls the Company or
United within the meaning of Section 15 of the 1933 Act, against any and all
loss, liability, claim, damage and expense described in the indemnity agreement
in Section (a), as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Company or United by the
Initial Purchaser expressly for use in the Registration Statement (or any
amendment thereto), or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto).

 
                                      17

          (c) In the case of a Shelf Registration, each Holder agrees,
severally and not jointly, to indemnify and hold harmless the Company, United,
the Initial Purchaser, each underwriter who participates in an offering of
Registrable Securities and the other selling Holders and each person, if any,
who controls such persons within the meaning of Section 15 of the 1933 Act,
against any and all losses, liabilities, claims, damages and expenses described
in the indemnity contained in (a) hereof, as incurred, but only with respect to
untrue statements or omissions, or alleged untrue statements or omissions, made
in the Registration Statement (or any amendment thereto) or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company or United by such Holder, expressly
for use in the Registration Statement (or any amendment thereto), or the
Prospectus (or any amendment or supplement thereto); provided, however, that no
                                                     --------  -------
such Holder shall be liable for any claims hereunder in excess of the amount of
net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Shelf Registration Statement.

          (d) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement.  An indemnifying party may participate
at its own expense in the defense of such action.  In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

          (e) In order to provide for just and equitable contribution in
circumstances under which the indemnity provided for in this Section 6 is for
any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms, the Company, United and the Initial
Purchaser shall contribute to the aggregate losses, liabilities, claims, damages
and expenses of the nature contemplated by such indemnity incurred by the
Company, United and the Initial Purchaser, as incurred, in such proportions that
the Initial Purchaser is responsible for that portion represented by the
percentage that the initial purchaser's discount appearing on the cover page of
the Prospectus bears to the price to investors appearing thereon, and the
Company and United are responsible for the balance; provided, however, that no
                                                    --------  -------         
person guilty of fraudulent misrepresentation (within the meaning of Section
1(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.  For purposes of this Section,
each person, if any, who controls the Initial Purchaser within the meaning of
Section 5 of the 1933 Act shall have the same rights to contribution as the
Initial Purchaser, and each director of the Company or United, each officer of
the Company or United who signed the Registration Statement, and each person, if
any, who controls the Company or United within the meaning of Section 5 of the
1933 Act shall have the same rights to contribution as the Company or United.

          7.   Miscellaneous.  (a)  Rule 144 and Rule 144A.  Regardless of
               -------------        ----------------------                
whether the Company is subject to the reporting requirements of Section 13 or 15
of the 1934 Act, the Company covenants that it will file the reports that would
be required to be filed by it

 
                                      18

under Section 13(a) or 15(d) of the 1934 Act and the rules and regulations
adopted by the SEC thereunder if such Sections were applicable to it, and that
if it ceases to be permitted to file such reports, it will upon the request of
any Holder of Registrable Securities (i) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act and (ii) deliver such information to a prospective purchaser as is
reasonably necessary to permit sales pursuant to Rule 144A under the 1933 Act,
in each case, to the extent required from time to time to enable such Holder to
sell its Registrable Securities without registration under the 1933 Act within
the limitation of the exemptions provided by (x) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, (y) Rule 144A under the 1993 Act, as
such Rule may be amended from time to time, or (z) any similar rules or
regulations hereafter adopted by the SEC.  Upon the request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such requirements.

          (b) No Inconsistent Agreements.  Neither the Company or United has
              --------------------------                                     
entered into nor will the Company or United on or after the date of this
Agreement enter into, any agreement which is inconsistent with the rights
granted to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof.   The Company and United represent and
warrant that the rights granted to the Holders hereunder do not conflict with
and are not inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities under any such agreements.

          (c) Amendments and Waivers.  The provisions of this Agreement,
              ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure; provided, however, that no amendment, modification,
                     --------  -------                                  
supplement or waiver or consent to any departure from the provisions of Section
6 hereof shall be effective as against any Holder of Registrable Securities
unless consented to in writing by such Holder.

          (d) Notices.  All notices and other communications provided for or
              -------

class mail, telex, telecopier, or any courier guaranteeing overnight delivery

Company by means of a notice given in accordance with the provisions of this
Section 7(d), which address initially is, with respect to the Initial Purchaser,
the address set forth in the Purchase Agreement and (ii) if to the Company,
initially at the Company's address set forth in the Purchase Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 7(d).

          All such notices and communications shall be deemed to have been duly
given  at the time delivered by hand, if personally delivered; three business
days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next business day if timely delivered to an air courier guaranteeing
overnight delivery.

 
                                      19

          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee, at the
address specified in the Indenture.

          (e) Successors and Assigns.  This Agreement shall inure to the benefit
              ----------------------                                            
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to

permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms hereof or of the Purchase Agreement or the Indenture.
If any transferee of any Holder shall acquire Registrable Securities, in any
manner, whether by operation of law or otherwise, such Registrable Securities
shall be held subject to all of the terms of this Agreement, and by taking and
holding such Registrable Securities, such Person shall be conclusively deemed to
have agreed to be bound by and to perform all of the terms and provisions of
this Agreement, including the restrictions on resale set forth in this Agreement
and, if applicable, the Purchase Agreement, and such Person shall be entitled to
receive the benefits hereof.

          (f) Third Party Beneficiary.  The Initial Purchaser shall be third
              -----------------------                                       
party beneficiary to the agreements made hereunder between the Company, on the
one hand, and the Holders, on the other hand, and shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

          (g) Counterparts.  This Agreement may be executed in any number of

counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h) Headings.  The headings in this Agreement are for convenience of
              --------                                                        
reference only and shall not limit or otherwise affect the meaning hereof.

          (i) GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
              -------------                                                    
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS
PERFORMED ENTIRELY IN THAT STATE.

          (j) Severability.  In the event that any one or more of the provisions
              ------------
