DTC to credit the Notes to the account of the Underwriters at DTC against

          5.   Agreements of the Issuers.  The Issuers, jointly and severally,
               -------------------------
agree with the Underwriters as follows:

          (a)   The Issuers will, if necessary or required by law, file an
     amendment to the Registration Statement or, if necessary pursuant to Rule
     430A under the Act, a post-effective amendment to the Registration
     Statement, as soon as practicable after the execution and delivery of this
     Agreement, and will use their best efforts to cause the Registration
     Statement or such post-effective amendment to become effective at the
     earliest possible time. The Company will comply fully and in a timely
     manner with the applicable provisions of Rule 424 and Rule 430A under the
     Act.

          (b)   The Issuers will advise you promptly and, if requested by you,
     will confirm such advice in writing: (i) of the effectiveness of any
     amendment to the Registration Statement; (ii) of the transmission to the
     Commission for filing of any supplement to the Prospectus (including any
     document that would as a result of such filing become an Incorporated
     Document) and to furnish you with copies thereof; (iii) of the receipt of
     any comments from the Commission that relate to the Registration Statement
     or of any request by the Commission for amendment of or a supplement to the
     Registration Statement or the Prospectus or for additional information;
     (iv) of the issuance by the Commission of any stop order suspending the
     effectiveness
<PAGE>
 
                                      -4-

     of the Registration Statement or any order preventing or suspending the use
     of the Prospectus or of the suspension of qualification of the Securities
     for offering or sale in any jurisdiction or the initiation or the
     threatening of any proceeding for such purpose; and (v) within the period
     of time referred to in paragraph (e) below, of any change in the Company's
     condition (financial or other), business, prospects, properties, net worth
     or results of operations, or of the happening of any event, which makes any
     statement of a material fact made in the Registration Statement or the
     Prospectus (as then amended or supplemented) untrue or which requires the
     making of any additions to or changes in the Registration Statement or the
     Prospectus (as then amended or supplemented) in order to state a material
     fact required to be stated therein or necessary in order to make the
     statements therein not misleading, or of the necessity to amend or
     supplement the Prospectus (as then amended or supplemented) to comply with
     the Act or any other law.  If at any time any stop order suspending the
     effectiveness of the Registration Statement or any order preventing or
     suspending the use of the Prospectus or suspending any such qualification
     shall be issued, the Issuers will promptly use their best efforts to obtain
     the withdrawal of such order at the earliest possible time.

          (c)   The Issuers will furnish to you, without charge, (i) five copies
     of the registration statement as originally filed with the Commission and
     of each amendment thereto, including all exhibits thereto, (ii) the
     Prospectus and any amendment or supplement thereto, (iii) such number of
     copies of the registration statement as originally filed and of each
     amendment thereto, but without exhibits, as you may request, (iv) such
     number of copies of the Incorporated Documents, without exhibits, as you
     may request, and (v) five copies of the exhibits to the Incorporated
     Documents.

          (d)   The Issuers will not file any amendment to the Registration
     Statement or make any amendment or supplement to the Prospectus or, prior
     to the end of the period of time referred to in paragraph (e) below, file
     any document which, upon filing becomes an Incorporated Document, of which
     you shall not previously have been advised or to which, after you shall
     have received a copy of the document proposed to be filed, you shall
     reasonably object.

          (e)   As soon after the execution and delivery of this Agreement as
     possible and thereafter from time to time for 
<PAGE>
 
                                      -5-

     such period as in the opinion of counsel for the Underwriters a prospectus
     is required by the Act to be delivered in connection with sales by the
     Underwriters or any dealer, the Issuers will expeditiously deliver to the
     Underwriters and each dealer, without charge, as many copies of the
     Prospectus (and of any amendment or supplement thereto) as you may
     reasonably request. The Issuers consent to the use of the Prospectus (and
     of any amendment or supplement thereto) in accordance with the provisions
     of the Act and with the securities or Blue Sky laws of the jurisdictions in
     which the Securities are offered by the Underwriters and by all dealers to
     whom Securities may be sold, both in connection with the offering and sale
     of the Securities and for such period of time thereafter as the Prospectus
     is required by the Act to be delivered in connection with sales by the
     Underwriters or any dealer.

          (f)   If during the period of time referred to in paragraph (e) above
     any event shall occur as a result of which, in the judgment of the Issuers
     or in the opinion of counsel for the Underwriters, it becomes necessary to
     amend or supplement the Prospectus in order to make the statements therein,
     in the light of the circumstances when the Prospectus is delivered to a
     purchaser, not misleading, or if it is necessary to amend or supplement the
     Prospectus to comply with the Act or any other law, the Issuers will
     forthwith prepare and, subject to the provisions of paragraph (d) above,
     file with the Commission an appropriate amendment or supplement to the
     Prospectus so that the statements in the Prospectus, as so amended or
     supplemented, will not, in the light of the circumstances when it is so
     delivered, be misleading, or so that the Prospectus will comply with law,
     and to furnish to the Underwriters and to such dealers as you shall specify
     such number of copies thereof as the Underwriters or such dealers may
     reasonably request. In the event that the Issuers and you agree that the
     Prospectus should be amended or supplemented, the Issuers, if requested by
     you, will promptly issue a press release announcing or disclosing the
     matters to be covered by the proposed amendment or supplement.

          (g)   The Issuers will cooperate with you and with counsel for the
     Underwriters in connection with the registration or qualification of the
     Securities for offering and sale by the Underwriters and by dealers under
     the securities or Blue Sky laws of such jurisdictions as you may designate
     and will file such consents to service of process or other documents
     necessary or appropriate in order 
<PAGE>
 
                                      -6-

     to effect such registration or qualification; provided, however, that in no
                                                   --------  -------
     event shall any Issuer be obligated to qualify to do business in any
     jurisdiction where it is not now so qualified or to take any action which
     would subject it to service of process in suits, other than those arising
     out of the offering or sale of the Securities, in any jurisdiction where it
     is not now so subject.

          (h)   The Issuers will make generally available to its security
     holders a consolidated earnings statement, which need not be audited,
     covering a twelve-month period commencing after the date the Registration
     Statement is declared effective by the Commission (the "Effective
                                                             ---------
     Date") and ending not later than 15 months thereafter, as soon as
     ----
     practicable after the end of such period, which consolidated earnings
     statement shall satisfy the provisions of Section 11(a) of the Act and Rule
     158 thereunder, and to advise you in writing when such statement has been
     made available.

          (i)   During the period of five years hereafter, the Issuers will
     furnish to you as soon as available, a copy of all public materials
     furnished by the Company to its stockholders and all public reports and
     financial statements furnished by the Company to the principal national
     securities exchange upon which the Common Stock may be listed pursuant to
     requirements of or agreements with such exchange or to the Commission.

          (j)   The Company will apply the net proceeds from the sale of the
     Notes in accordance with the description set forth in the Prospectus under
     the caption "Use of Proceeds."

          (k)   Neither the Company nor any of its subsidiaries has taken, or
     will 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 Notes to facilitate the sale or resale of the Notes.

          (l)   The Issuers will pay all costs, expenses, fees and taxes
     incident to (i) the preparation, printing, filing and distribution under
     the Act of the Registration Statement (including financial statements and
     exhibits), and all amendments and supplements thereto prior to or during
     the period specified in paragraph (e) above, (ii) the printing and delivery
     of the Prospectus and all
<PAGE>
 
                                      -7-

     amendments or supplements thereto during the period specified in paragraph
     (e) above, (iii) the printing and delivery of this Agreement, the
     Preliminary and Supplemental Blue Sky Memoranda and all other agreements,
     memoranda, correspondence and other documents printed and delivered in
     connection with the offering of the Securities (including in each case any
     disbursements of counsel for the Underwriters relating to such printing and
     delivery), (iv) the registration or qualification of the Securities for
     offer and sale under the securities or Blue Sky laws of the several states
     (including in each case the reasonable fees and disbursements of counsel
     for the Underwriters relating to such registration or qualification and
     memoranda relating thereto), (v) filings and clearance with the National
     Association of Securities Dealers, Inc. in connection with the offering,
     (vi) the listing, if any, of the Securities on any national securities
     exchange, and (vii) furnishing such copies of the Registration Statement,
     the Prospectus and all amendments and supplements thereto as may be
     requested for use in connection with the offering or sale of the Securities
     by the Underwriters or by dealers to whom Securities may be sold.

          (m)   The Issuers 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 securities of the Company
     or any warrants, options or other rights to purchase or acquire debt
     securities of the Company or any securities convertible into or
     exchangeable for debt securities of the Company (other than (i) the
     Securities and (ii) commercial paper issued in the ordinary course of
     business), without the prior written consent of Donaldson, Lufkin &
     Jenrette Securities Corporation.

          (n)   The Issuers will use their best efforts to do and perform all
     things required or necessary to be done and performed under this Agreement
     by the Issuers prior to the Closing Date and to satisfy all conditions

          6.   Representations and Warranties of the Issuers.  The Issuers,
               ---------------------------------------------
jointly and severally, represent and warrant to the Underwriters that:

          (a)   Each preliminary prospectus included as part of the registration
     statement as originally filed or as part of any amendment or supplement
     thereto, or filed pursuant 
<PAGE>
 
                                      -8-

     to Rule 424 under the Act, complied when so filed in all material respects
     with the provisions of the Act. The Commission has not issued any order
     preventing or suspending the use of any preliminary prospectus.

          (b)   The Registration statement has become effective and at the date
     of the Prospectus (if different), including at the date of any post-
     effective amendment or supplement, the Registration Statement will comply
     in all material respects with the provisions of the Act, and will not
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading; the Prospectus (and any supplements or
     amendments thereto) will at all such times comply in all material respects
     with the provisions of the Act and will not at any such time contain any
     untrue statement of a material fact or omit to state any material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
                                                               --------
     however, that no representation or warranty is made as to information
     -------
     contained in or omitted from the Registration Statement or the Prospectus
     in reliance upon and in conformity with written information furnished to
     the Issuers with respect to the Underwriters specifically for inclusion
     therein.

          (c)   The Incorporated Documents, at the time they were filed with the
     Commission or, to the extent such documents were subsequently amended prior
     to the date hereof, at the time so amended, complied in all material
     respects with the requirements of the Act or the Securities Exchange Act of
     1934, as amended, and the published rules and regulations of the Commission
     thereunder (collectively, the "Exchange Act"), as applicable, and such
                                    ------------                           
     documents do not on the date hereof and will not on the Closing Date
     contain an untrue statement of a material fact and do not on the date
     hereof and will not on the Closing Date omit to state a material fact
     required to be stated therein or necessary to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading.

          (d)   The financial statements (including the related notes and
     supporting schedules) in the Registration Statement or the Prospectus
     present fairly the consolidated financial position and results of
     operations of the entities purported to be shown thereby, at the dates and
     for the

                                      -9-

     periods indicated, and have been prepared in conformity with generally
     accepted accounting principles applied on a consistent basis throughout the
     periods involved.

          (e)   Each of Ernst & Young, LLP and Arthur Andersen LLP who have
     reported on the financial statements of the Company, are independent public
     accountants with respect to the Company and its subsidiaries as required by
     the Act.

          (f)   The material assumptions used in the preparation of the pro
     forma financial statements and other pro forma information in the
     Prospectus are set forth therein and were reasonable when made, and the
     adjustments used therein are appropriate to give pro forma effect to the
     transactions or circumstances referred to therein.

          (g)   The Company and each of its subsidiaries have been duly formed
     and are validly existing in good standing under the laws of their
     respective jurisdictions of organization, are duly qualified to do business
     and are in good standing in each jurisdiction in which their respective
     ownership or lease of property or the conduct of their respective
     businesses requires such qualification except where the failure to so
     qualify, singly or in the aggregate, would not have a material adverse
     effect on the financial condition, results of operations, business or
     prospects of the Company and its subsidiaries taken as a whole (a "Material
                                                                        --------
     Adverse Effect"), and have all power and authority necessary to own or hold
     --------------
     their respective properties and to conduct the businesses in which they are
     engaged.

          (h)   The Company has an authorized capitalization as set forth in the
     Prospectus; and all of the issued equity interests of each subsidiary of
     the Company have been duly authorized and validly issued and, as to shares
     of capital stock of any corporation constituting a subsidiary, are fully
     paid and non-assessable and (except for directors' qualifying shares) are
     owned directly or indirectly by the Company, free and clear of all liens,
     encumbrances, equities or claims other than restrictions on transfer
     imposed by applicable securities laws.

          (i)   The execution, delivery and performance of this Agreement, the
     Indenture and the Securities by the issuers, compliance by the Issuers of
     all the provisions hereof and thereof and the consummation of the transac-
<PAGE>
 
                                      -10-

     tions contemplated hereby will not conflict with or result in a breach or
     violation of any of the terms or provisions of, or constitute a default
     under, any indenture, mortgage, deed of trust, loan agreement or other
     material agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which the Company or any of its subsidiaries
     is bound or to which any of the property or assets of the Company or any of
     its subsidiaries is subject, nor will such actions result in any violation
     of the provisions of the organizational documents of the Company or any of
     its subsidiaries or any statute or any order, rule or regulation of any
     court or governmental agency or body having jurisdiction over the Company
     or any of its subsidiaries or any of their property or assets; and except
     for such consents, approvals, authorizations, registrations or
     qualifications as may be required under the Act or applicable state or
     foreign securities laws in connection with the purchase and distribution of
     the Securities by the Underwriters, no consent, approval, authorization or
     order of, or filing or registration with, any such court or governmental
     agency or body is required for the execution, delivery and performance of
     this Agreement, the Indenture and the Securities by the Issuers, compliance
     by the Issuers of all the provisions hereof and thereof and the
     consummation of the transactions contemplated hereby.

          (j)   This Agreement has been duly authorized, executed and delivered
     by the Issuers and is a valid and binding agreement of the Issuers
     enforceable in accordance with its terms (except as rights to indemnity and
     contribution hereunder may be limited by applicable law).

          (k)   The Indenture has been duly qualified under the Trust Indenture
     Act of 1939, as amended (the "TIA"), and has been duly authorized, executed
                                   ---
     and delivered by the Issuers and is a valid and binding agreement of the
     Issuers, enforceable in accordance with its terms except as (i) the
     enforceability thereof may be limited by bankruptcy, insolvency or similar
     laws affecting creditors' rights generally and (ii) rights of acceleration
     and the availability of equitable remedies may be limited by equitable
     principles of general applicability.

          (l)   The Notes have been duly authorized and, when executed and

     Agreement,
<PAGE>
 
                                      -11-

     will be entitled to the benefits of the Indenture, and will be valid and
     binding obligations of the Company, enforceable in accordance with their
     terms except as (i) the enforceability thereof may be limited by
     bankruptcy, insolvency or similar laws affecting creditors' rights
     generally and (ii) rights of acceleration and the availability of equitable
     remedies may be limited by equitable principles of general applicability.

          (m)   The Guarantees have been duly authorized and, upon endorsement
     on the Notes by the Guarantors, execution and authentication of the Notes
     in accordance with the provisions of the Indenture and delivery of the
     Notes to the Underwriters against payment therefor as provided by this
     Agreement, will be entitled to the benefits of the Indenture, and will be
     valid and binding obligations of the Guarantors, enforceable in accordance
     with their terms except as (i) the enforceability thereof may be limited by
     bankruptcy, insolvency or similar laws affecting creditors' rights
     generally and (ii) rights of acceleration and the availability of equitable
     remedies may be limited by equitable principles of general applicability.

          (n)   The Securities and the Indenture conform to the description
     thereof in the Prospectus.

          (o)   Neither the Company nor any of its subsidiaries has sustained,
     since the date of the latest audited financial statements in the
     Prospectus, any loss or interference with the business of the Company and
     its subsidiaries taken as a whole from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth
     or contemplated in the Prospectus, resulting in a Material Adverse Effect;
     and, since such date, there has not been any change in the capital stock or
     long-term debt of the Company or any of its subsidiaries or any material
     adverse change, or any development involving a prospective material adverse
     change, in or affecting the general affairs, management, financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries taken as a whole, otherwise than as set forth or
     contemplated in the Prospectus.

          (p)   There are no contracts, agreements or understandings between the
     Company and any person granting such person the right to require the
     Company to file a regis-
<PAGE>
 
                                      -12-

     tration statement under the Act with respect to any securities of the
     Company owned or to be owned by such person or to require the Company to
     include such securities in the securities registered pursuant to the
     Registration Statement or in any securities being registered pursuant to
     any other registration statement filed by the Company under the Act.

          (q)   The Company and its subsidiaries own the items of real property
     and personal property purported to be owned by them which are material to
     the conduct of the business of the Company and its subsidiaries taken as a
     whole, free and clear of all liens, encumbrances and defects, except such
     as are described in the Prospectus or such as would not have a Material
     Adverse Effect. All real property held under lease by the Company and its
     subsidiaries are held by them under valid, subsisting and enforceable
     leases, with such exceptions as are described in the Prospectus or such as
     would not have a Material Adverse Effect.

          (r)   Except as described in the Prospectus, there are no legal or
     governmental proceedings pending to which the Company or any of its
     subsidiaries is a party or of which any property or assets of the Company
     or any of its subsidiaries is the subject which are reasonably likely to
     have a Material Adverse Effect; and to the Issuers' knowledge, no such
     proceedings are threatened by governmental authorities or by others.

          (s)   The conditions for use of Form S-3, as set forth in the General
     Instructions thereto, have been satisfied.

          (t)   To the Issuers' knowledge, all real property owned (either
     presently or at any time in the past) or presently leased by the Company
     and its subsidiaries in connection with the operation of their business,
     including, without limitation, any subsurface soils and ground water
     (collectively, the "Realty"), is free of contamination from any substance
                         ------
     or material presently known to be toxic or hazardous, including, without
     limitation, any radioactive substance, methane, volatile hydrocarbons or
     industrial solvents (each, a "Hazardous Substance"), which could reasonably
                                   -------------------
     be expected to materially impair the beneficial use thereof by the Company
     and its subsidiaries or constitute or cause a significant health, safety or
     other environmental hazard to occupants or users (except for contaminations
     which would not have a Material Adverse
<PAGE>
 
                                      -13-

     Effect); and to the Issuers' knowledge, the Realty does not contain any
     underground storage or treatment tanks, active or abandoned water, gas or
     oil wells, or any other underground improvements or structures, other than
     the foundations, footings or other supports for the improvements located
     thereon, the presence of which would have a Material Adverse Effect.
     Notwithstanding the foregoing, Hazardous Substances shall be deemed not to
     include any supplies or substances maintained, used, stored or held on the
     Realty which are (i) naturally occurring, (ii) installed by public
     utilities or (iii) used in the ordinary course of the Company's or its
     subsidiaries' business, provided that such supplies or substances are
     stored, used, maintained and held in all material respects in accordance
     with any applicable governmental requirements and with restrictions,
     conditions and standards suggested by the manufacturer and the Company's
     insurance carriers.

          (u)   The Company and its subsidiaries carry, or are covered by,
     insurance in such amounts and covering such risks as is adequate for the
     conduct of their respective businesses.

          (v)   The Company and its subsidiaries own or possess adequate rights
     to use all material patents, patent applications, trademarks, service
     marks, trade names, trademark registrations, service mark registrations,
     copyrights and licenses necessary for the conduct of their respective
     businesses the absence of which would have a Material Adverse Effect and
     have no reason to believe that the conduct of their respective businesses
     will conflict with, and have not received any notice of any claim of
     conflict with, any such rights of others.

          (w)   There are no contracts or other documents which are required to
     be described in the Prospectus or filed as exhibits to the Registration
     Statement by the Act which have not been described in the Prospectus or
     filed as exhibits to the Registration Statement or incorporated therein by
     reference as permitted by the Act.

          (x)   No labor disturbance by the employees of the Company or any of
     its subsidiaries exists or, to the Issuers' knowledge, is imminent which
     could reasonably be expected to have a Material Adverse Effect.

          (y)   The Company and its subsidiaries have filed all federal, state
     and local income and franchise tax returns 
<PAGE>
 
                                      -14-

     required to be filed through the date hereof and has paid all taxes due
     thereon, and no tax deficiency has been determined adversely to the Company
     or any of its subsidiaries which has had (nor does any Issuer have any
     knowledge of any tax deficiency which would reasonably likely have) a
     Material Adverse Effect.

          (z)   Since the date as of which information is given in the
     Prospectus, and except as may otherwise be disclosed in the Prospectus,
     neither the Company nor any of its subsidiaries has (i) entered into any
     material transaction not in the ordinary course of business or (ii) except
     for the dividend of $.03 per share declared in January 1999, declared or
     paid any dividend on its capital stock from the date of the Prospectus,
     neither the Company nor any of its subsidiaries has incurred any material
     liability other than in the ordinary course of business.

          (aa)  The Company is in full compliance with Section 13(b)(2) of the
     Exchange Act.

          (bb)  Neither the Company nor any of its subsidiaries (i) is in
     violation of its organizational documents, (ii) is in default in any
     material respect, and no event has occurred which, with notice or lapse of
     time or both, would constitute such a default, in the due performance or
     observance of any term, covenant or condition contained in any indenture,
     mortgage, deed of trust, loan agreement or other material agreement or
     instrument to which it is a party or by which it is bound or to which any
     of its properties or assets is subject as a result of which default there
     would be a Material Adverse Effect or (iii) is in violation of any law,
     ordinance, governmental rule, regulation or court decree to which it or its
     property or assets may be subject or has failed to obtain any license,
     permit, certificate, franchise or other governmental authorization or
     permit necessary to the ownership of its property or to the conduct of its
     business which violation or failure would have a Material Adverse Effect.

          (cc)  Neither the Company nor any of its subsidiaries is an
     "investment company" or an entity "controlled" by an "investment company"
     within the meaning of the Investment Company Act of 1940, as amended, and
     the rules and regulations of the Commission thereunder.

          7.   Indemnification.  (a)  The Issuers, jointly and severally, agree
               ---------------
to indemnify and hold harmless the Underwrit-
<PAGE>
 
                                      -15-

ers and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages, liabilities and judgments caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or the Prospectus (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to the Underwriters furnished in writing to the Issuers by or on behalf of the
Underwriters expressly for use therein; provided, however, that the foregoing
                                        --------  -------
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter or any person controlling such Underwriter
asserted by a person with respect to any such losses, claims, damages and
liabilities and judgments, if a copy of the Prospectus (as then amended or
supplemented if the Issuers shall have furnished such amendment or supplement
thereto in the requisite quantity on a timely basis to permit such sending or
giving) was not sent or given by or on behalf of the Underwriters to such
person, if required by law so to have been delivered, at or prior to the written
confirmation of the sale of Notes to such person, and if the Prospectus (as so
amended and supplemented) would have cured the defect giving rise to such loss,
claim, damage, liability or judgment. Notwithstanding anything to the contrary
herein, the Underwriters shall not be obligated to send or give any Incorporated
Document, or any amendment or supplement thereto, to any person in order to
benefit from the indemnity provisions herein or otherwise. The foregoing
indemnity agreement shall be in addition to any liability that the Issuers may
otherwise have.
 
     (b)   In case any action shall be brought against any Underwriter or any
person controlling any Underwriter, based upon any preliminary prospectus, the
Registration Statement or the Prospectus or any amendment or supplement thereto
and with respect to which indemnity may be sought against the Issuers, such
Underwriter shall promptly notify the Issuers in writing and the Issuers shall
assume the defense thereof, including the employment of counsel reasonably
satisfactory to such indemnified party and payment of all fees and expenses. The
Underwriters or any such controlling person shall have the right to employ
separate counsel in any such action and participate in
<PAGE>
 
                                      -16-

     the defense thereof, but the fees and expenses of such counsel shall be at
     the expense of such Underwriter or such controlling person unless (i) the
     employment of such counsel shall have been specifically authorized in
     writing by the Issuers, (ii) the Issuers shall have failed to assume the
     defense and employ counsel or (iii) the named parties to any such action
     (including any impleaded parties) include both such Underwriter or such
     controlling person and the Issuers and such Underwriter or such controlling
     person shall have been advised by such counsel that there may be one or
     more legal defenses available to it which are different from or additional
     to those available to the Issuers (in which case the Issuers shall not have
     the right to assume the defense of such action on behalf of such
     Underwriter or such controlling person, it being understood, however, that
     the Issuers shall not, in connection with any one such action or separate
     but substantially similar or related actions in the same jurisdiction
     arising out of the same general allegations or circumstances, be liable for
     the fees and expenses of more than one separate firm of attorneys (in
     addition to any local counsel) for the Underwriters and all such
     controlling persons, which firm shall be designated in writing by
     Donaldson, Lufkin & Jenrette Securities Corporation and that all such fees
     and expenses shall be reimbursed as they are incurred). The Issuers shall
     not be liable for any settlement of any such action effected without the
     Company's written consent but if settled with the written consent of the
     Company, the Issuers agree to indemnify and hold harmless the Underwriters
     and any such controlling person from and against any loss or liability by
     reason 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.

          (c)   Each Underwriter, severally and not jointly, agrees to indemnify
     and hold harmless the Issuers, their directors, their officers who sign the
     Registration Statement and any person controlling the Issuers within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the
     same extent as the foregoing indemnity from the Issuers to the Underwriters
     but only with reference to information relating to such Underwriter
     furnished in writing by or on behalf of the Underwriter expressly for use
     in the Registration Statement, the Prospectus or any preliminary
     prospectus. In case any ac-
<PAGE>
 
                                      -17-

tion shall be brought against the Issuers, any of its directors, any such
officer or any person controlling the Issuers based on the Registration
Statement, the Prospectus or any preliminary prospectus and in respect of which
indemnity may be sought against the Underwriters, the Underwriters shall have
the rights and duties given to the Issuers (except that if the Issuers shall
have assumed the defense thereof, the Underwriters shall not be required to do
so, but may employ separate counsel therein and participate in the defense
thereof but the fees and expenses of such counsel shall be at the expense of the
Underwriters), and the Issuers, their directors, any such officers and any
person controlling the Issuers shall have the rights and duties given to the
Underwriters, by Section 7(b) hereof.

          (d)   If the indemnification provided for in this Section 7 is
unavailable to an indemnified party in respect of any losses, claims, damages,
liabilities or judgments referred to therein, then each indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable by such indemnified party as a result of such losses, claims,
damages, liabilities and judgments (i) in such proportion as is appropriate to
reflect the relative benefits received by the Issuers on the one hand and the
Underwriters on the other hand from the offering of the Securities or (ii) if
the allocation provided by clause (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 (i) above but also the relative fault of the Issuers and
the Underwriters in connection with the statements or omissions which resulted
in such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative benefits received by the Issuers
and the Underwriters shall be deemed to be in the same proportion as the total
net proceeds from the offering (before deducting expenses) received by the
Company, and the compensation received by the Underwriters (based on discount to
investors on resale), bear to the sum of such total net proceeds and such
compensation. The relative fault of the Issuers and the Underwriters shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Issuers or the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

          The Issuers and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Sec-
<PAGE>
 
                                      -18-

tion 7(d) were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, liabilities or
judgments referred to in the immediately preceding paragraph 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 7, the Underwriters shall not be required to contribute any amount in
excess of the amount by which the total price at which the Notes underwritten by
it and distributed to the public were offered to the public exceeds the amount
of any damages which such Underwriter 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 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          In rendering such opinion, such counsel may state that its opinion is
limited to the Federal laws of the United States of America, the laws of the
States of Texas and New York and the General Corporation Law of the State of
Delaware.  Such counsel shall also have furnished to the Underwriters a written
statement, addressed to the Underwriters and dated the Closing Date, in form and
substance satisfactory to the Underwriters and counsel for the Underwriters, to
the effect that (x) such counsel has acted as special counsel to the Company in
connection with the preparation of the Registration Statement and during the
course of the preparation of the Registration Statement and Prospectus, such
counsel participated in conferences with representatives of the Company, the
Company's internal counsel, and its accountants and the representatives of the
Underwriters and at which conferences the contents of the Registration Statement
and the Prospectus and related matters were discussed, and (y) based on the
foregoing, no facts have come to the attention of such counsel which lead it to
believe that (I) the Registration Statement (except as to financial and pro
forma data (and related notes thereto) and statistical data and the financial
statements and related schedules contained or incorporated by reference
therein), as of the date the Registration Statement became effective, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, or that the Prospectus (except as to financial and pro
forma data (and related notes thereto) and statistical data and the financial
statements and 
<PAGE>
 
                                      -24-

related schedules contained or incorporated by reference therein) contains any
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading or (II)
any Incorporated Document or any amendment or supplement thereto made by the
Company prior to such Closing Date, when they were filed with the Commission, as
the case may be, contained (except as to financial and pro forma data (and
related notes thereto) and statistical data and the financial statements and
related schedules contained or incorporated by reference therein) an untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The foregoing opinion and statement may be
qualified by a statement to the effect that such counsel has not independently
verified the accuracy, completeness or fairness of the statements contained in
the Registration Statement or Prospectus or incorporated by reference therein,
and such counsel is not passing upon and such counsel does not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus.

          (g)   You shall have received on the Closing Date, an opinion of
     Charles N. Warren, Esq., General Counsel of the Company, dated the Closing
     Date and addressed to you, to the effect that:

                (i)    The issue and sale of the Securities by the Issuers and
          the compliance by the Issuers with all of the provisions of this
          Agreement and the consummation by the Issuers of the transactions
          contemplated hereby will not, to such counsel's knowledge, conflict
          with or result in a material breach or violation of any of the terms
          or provisions of, or constitute a material default under, any
          indenture, mortgage, deed or trust, loan agreement or other material
          agreement or instrument known to such counsel to which the Company or
          any of its subsidiaries is a party or by which the Company or any of
          its subsidiaries is bound or to which any of the property or assets of
          the Company or any of its subsidiaries is subject, nor will such
          actions result in any violation of the provisions of the charter or 
          by-laws of any Issuer or any order, rule or regulation known to such
          counsel of any court or governmental agency or body having
          jurisdiction over any Issuer or any of their property or assets.

                (ii)   Each Guarantor that is a corporation has been duly
          incorporated and is validly existing as a corporation in good standing
          under the laws of its state of incorporation, is duly qualified to do
          business and is in good standing as a foreign corporation in each
          jurisdiction in which its ownership or lease of its property or the
          conduct of its business requires such qualification, except where the
          failure
<PAGE>
 
                                      -25-

          to be so qualified would not have a material adverse effect on the
          business, operations or financial condition of the Company and its
          subsidiaries taken as a whole, and has all corporate power and
          authority necessary to own or hold its properties and conduct its
          business as described in the Prospectus. The outstanding shares of
          capital stock of each such Guarantor is duly authorized, validly
          issued, fully paid and nonassessable and (except for directors'
          qualifying shares) are owned of record, directly or indirectly by the
          Company. Each Guarantor that is a limited partnership has been duly
          formed and is validly existing as a limited partnership in good
          standing under the laws of the state of its organization, is duly
          qualified to do business and is in good standing as a foreign limited
          partnership in each jurisdiction in which its ownership or lease of-
          its property or the conduct of its business requires such
          qualification, except where the failure to be so qualified would not
          have a material adverse effect on the business, operation or financial
          condition of the Company and its subsidiaries taken as a whole, and
          has all partnership power and authority necessary to own or hold its
          properties and conduct its business as described in the Prospectus.

          (h)   You shall have received on the Closing Date an opinion, dated
     the Closing Date, of Cahill Gordon and Reindel, counsel for the
     Underwriters, in form and substance satisfactory to the Underwriters.

          (i)   You shall have received a letter on and as of the Closing Date,
     in form and substance satisfactory to you, from Ernst & Young, LLP,
     independent public accountants, with respect to the financial statements
     and certain financial information contained in the Registration Statement
     and the Prospectus and substantially in the form and substance of the
     letter delivered to you by Ernst & Young, LLP, on the date of this
     Agreement.

          (j)   (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements in the
     Prospectus any loss or interference with its business from fire, explosion,
     flood or other calamity, whether or not covered by insurance, or from any
     labor dispute or court or governmental action, order or decree, otherwise
     than as set forth or contemplated in the Prospectus or (ii) since such date
     there
<PAGE>
 
                                      -26-

     shall not have been any change in the capital stock, net revenues, per
     share or total amounts of income before extraordinary income or of net
     income or long-term debt of the Company or any of its subsidiaries or any
     change, or any development involving a prospective change, in or affecting
     the general affairs, management, financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, otherwise
     than as set forth or contemplated in the Prospectus, the effect of which,
     in any such case described in clause (i) or (ii), is, in the judgment of
     the Underwriters, so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Securities being delivered on the Closing Date on the terms and in the
     manner contemplated in the Prospectus.

          (k)   The Issuers shall have furnished to you such other documents and
     certificates as to the accuracy and completeness of any statement in the
     Registration Statement or the Prospectus as you reasonably may request.

          (l)   You shall have been furnished with such additional documents and
     certificates as you or counsel for the Underwriters may reasonably request.

          All such opinions, certificates, letters and other documents will be
in compliance with the provisions hereof only if they are reasonably
satisfactory in form and substance to you and your counsel.

          Any certificate or document signed by any officer of the Issuers and
delivered to you or to your counsel shall be deemed a representation and
warranty by the Issuers to each Underwriter as to the statements made therein.

          9.    Termination.

financial or otherwise, of the Issuers and its subsidiaries or the earnings,
affairs, or business prospects of the Issuers or any of its subsidiaries taken
as a whole, whether or not arising in the ordinary course of business, which
would, in your judgment, make it impracticable to market the Securities

on the terms and in the manner contemplated in the Prospectus, (ii) any outbreak
or escalation of hostilities or other national or international calamity or

          WHEREAS, the conditions set forth in the Indenture for the execution

<PAGE>
 
                                      -2-


denture is supplemented and amended, to the extent expressed herein, as follows:


                                  ARTICLE ONE

                    Scope of Supplemental Indenture; General

          The changes, modifications and supplements to the Indenture effected
by this Supplemental Indenture shall be applicable only with respect to, and
govern the terms of, the Notes, which shall be limited in aggregate principal
amount to $400,000,000 in one or more series, and shall not apply to any other
Securities that may be issued under the Indenture unless a supplemental
indenture with respect to such other Securities specifically incorporates such
changes, modifications and supplements.  Pursuant to this Supplemental
Indenture, there is hereby created and designated a series of Securities under
the Indenture entitled "8% Senior Notes due 2009."  The Notes shall be in the
form of Exhibit A hereto.  The Notes shall be guaranteed by the Guarantors as
        ---------                                                            
provided in such form and the Indenture.  If required, the Notes may bear an
appropriate legend regarding original issue discount for federal income tax
purposes.

          In the event that the Company shall issue and the Trustee shall
authenticate any Notes issued under this Supplemental Indenture subsequent to
the Issue Date (such Notes, "Additional Securities"), the Company shall use its
                             ---------------------                             
best efforts to obtain the same "CUSIP" number for such Notes as is printed on
the Notes outstanding at such time; provided, however, that if any series of
                                    --------  -------                       
Notes issued under this Supplemental Indenture subsequent to the Issue Date is
determined, pursuant to an Opinion of Counsel of the Company in a form
reasonably satisfactory to the Trustee, to be a different class of security than
the Notes outstanding at such time for federal income tax purposes, the Company
may obtain a "CUSIP" number for such Notes that is different than the "CUSIP"
number printed on the Notes then outstanding.  Notwithstanding the foregoing,
all Notes issued under this Supplemental Indenture shall vote and consent
together on all matters as one class and no series of Notes will have the right
to vote or consent as a separate class on any matter.

          "Unrestricted Subsidiary" means any Subsidiary of the Company so
           -----------------------                                        
designated by a resolution adopted by the Board of Directors of the Company or a
duly authorized committee thereof as provided below; provided that (a) the
                                                     --------             
holders of Indebtedness thereof do not have direct or indirect recourse against
the Company or any Restricted Subsidiary, and neither the Company nor any
Restricted Subsidiary otherwise has liability, for any payment obligations in
respect of such Indebtedness (including any undertaking, agreement or instrument
evidencing such Indebtedness), except, (i) in each case, to the extent that the
amount thereof constitutes a Restricted Payment permitted by the Indenture, (ii)
in the case of Non-Recourse Indebtedness, to the extent such recourse or
liability is for the matters discussed in the last sentence of the definition of
"Non-Recourse Indebtedness," or (iii) to the extent such Indebtedness is a
guarantee by such Subsidiary of Indebtedness of the Company or a Restricted
Subsidiary and (b) no holder of any Indebtedness of such Subsidiary shall have a
right to declare a default on such Indebtedness or cause the payment thereof to
be accelerated or payable prior to its stated maturity as a result of a default
on any Indebtedness of the Company or any Restricted Subsidiary.  Subject to the
foregoing, the Board of Directors of the Company or a duly authorized committee
thereof may designate any Subsidiary to be an Unrestricted Subsidiary; provided,
                                                                       -------- 
however, that (i) the net amount (the "Designation Amount") then outstanding of
- -------                                ------------------                      
all previous Investments by the Company and the Restricted Subsidiaries in such
Subsidiary will be deemed to be a Restricted Payment at the time of such
designation and will reduce the amount available for Restricted Payments under
Section 3.03 hereof, to the extent provided therein, (ii) the Company must be
permitted under Section 3.03 hereof to make the Restricted Payment deemed to
have been made pursuant to clause (i), and (iii) after giving effect to such
designation, no Default or Event of Default shall have occurred and be
continuing.  In accordance with the foregoing, and not in limitation thereof,
Investments made by any Person in any Subsidiary of such Person prior to such
Person's merger with the Company or any Restricted Subsidiary (but not in
contemplation or anticipation of such merger) shall not be counted as an
Investment by the Company or such Restricted Subsidiary if such Subsidiary of
such Person is designated as an Unrestricted Subsidiary.  The Board of Directors
of the Company or a duly authorized committee thereof may also redesignate an
Unrestricted Subsidiary to be a Restricted Subsidiary; provided, however, that
                                                       --------  -------      
(i) the Indebtedness of such Unrestricted Subsidiary as of the date of such
redesignation could then be incurred under Section 3.02 hereof and (ii)
immediately after giving effect to such redesignation and the incurrence of any
<PAGE>
 
                                      -25-

such additional Indebtedness, the Company and the Restricted Subsidiaries could
incur $1.00 of additional Indebtedness under Section 3.02(a) hereof.  Any such
designation or redesignation by the Board of Directors of the Company or a
committee thereof will be evidenced to the Trustee by the filing with the
Trustee of a certified copy of the resolution of the Board of Directors of the
Company or a committee thereof giving effect to such designation or
redesignation and an Officers' Certificate certifying that such designation or
redesignation complied with the foregoing conditions and setting forth the
underlying calculations of such Officers' Certificate.  The designation of any
Person as an Unrestricted Subsidiary shall be deemed to include a designation of
all Subsidiaries of such Person as Unrestricted Subsidiaries; provided, however,
                                                              --------  ------- 
that the ownership of the general partnership interest (or a similar member's
interest in a limited liability company) by an Unrestricted Subsidiary shall not
cause a Subsidiary of the Company of which more than 95% of the equity interest
is held by the Company or one or more Restricted Subsidiaries to be deemed an
Unrestricted Subsidiary.

          "Weighted Average Life to Maturity" means, when applied to any
           ---------------------------------                            
Indebtedness or portion thereof at any date, the number of years obtained by
dividing (i) the sum of the products obtained by multiplying (a) the amount of
each then remaining installment, sinking fund, serial maturity or other required
payment of principal, including, without limitation, payment at final maturity,
in respect thereof, by (b) the number of years (calculated to the nearest one-
twelfth) that will elapse between such date and the making of such payment by
(ii) the sum of all such payments described in clause (i)(a) above.

                                   Covenants

Section 3.01.  Repurchase of Notes upon Change of Control
- --------                                                 

          (a)  In the event that there shall occur a Change of Control, each
Holder of Notes shall have the right, at such Holder's option, to require the
Company to purchase all or any part of such Holder's Notes on a date (the
                                                                         
"Repurchase Date") that is no later than 90 days after notice of the Change of
 ---------------                                                              
Control, at 101% of the principal amount thereof plus accrued interest to the
Repurchase Date.

          (b)  On or before the thirtieth day after any Change of Control, the
Company is obligated to mail, or cause to be
<PAGE>
 
                                      -26-

mailed, to all Holders of record of Notes a notice regarding the Change of
Control and the repurchase right. The notice shall state the Repurchase Date,
the date by which the repurchase right must be exercised, the price for the
Notes and the procedure which the Holder must follow to exercise such right.
Substantially simultaneously with mailing of the notice, the Company shall cause
a copy of such notice to be published in a newspaper of general circulation in
the Borough of Manhattan, The City of New York. To exercise such right, the
Holder of such Note must deliver at least ten days prior to the Repurchase Date
written notice to the Company (or an agent designated by the Company for such
purpose) of the Holder's exercise of such right, together with the Note with
respect to which the right is being exercised, duly endorsed for transfer;
provided, however, that if mandated by applicable law, a Holder may be permitted
- --------  ------- 
to deliver such written notice nearer to the Repurchase Date than may be
specified by the Company.

          (c)  The Company will comply with applicable law, including Section
14(e) of the Exchange Act and Rule 14e-1 thereunder, if applicable, if the
Company is required to give a notice of right of repurchase as a result of a
Change of Control.

Section 3.02.  Limitations on Indebtedness.
               ---------------------------

          (a)  Until the Notes are rated Investment Grade by both Rating
Agencies (after which time the following covenant will no longer be in effect),
the Company will not, and will not cause or permit any Restricted Subsidiary,
directly or indirectly, to, create, incur, assume, become liable for or
guarantee the payment of (collectively, an "incurrence") any Indebtedness
                                            ----------                   
(including Acquired Indebtedness) unless, after giving effect thereto and the
application of the proceeds therefrom, the Consolidated Fixed Charge Coverage
Ratio on the date thereof would be at least 2.0 to 1.0.

          (b)  Notwithstanding the foregoing, the provisions of this
Supplemental Indenture will not prevent the incurrence of: (i) Permitted
Indebtedness, (ii) Refinancing Indebtedness, (iii) Non-Recourse Indebtedness,
(iv) any Guarantee of Indebtedness of the Company represented by the Notes and
(v) any guarantee of Indebtedness incurred under Credit Facilities in compliance
with this Indenture.

          (c)  For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness may be incurred through the first paragraph
of this covenant or by meeting the criteria of one or more of the types of
Indebtedness
<PAGE>
 
                                      -27-

described in the second paragraph of this covenant (or the definitions of the
terms used therein), the Company, in its sole discretion, (i) may classify such
item of Indebtedness under and comply with either of such paragraphs (or any of
such definitions), as applicable, (ii) may classify and divide such item of
Indebtedness into more than one of such paragraphs (or definitions), as
applicable, and (iii) may elect to comply with such paragraphs (or definitions),
as applicable, in any order.

          (d)  The Company will not, and will not cause or permit any Guarantor
to, directly or indirectly, in any event incur any Indebtedness that purports to
be by its terms (or by the terms of any agreement governing such Indebtedness)
subordinated to any other Indebtedness of the Company or of such Guarantor, as
the case may be, unless such Indebtedness is also by its terms (or by the terms
of any agreement governing such Indebtedness) made expressly subordinated to the
Notes or the Guarantee of such Guarantor, as the case may be, to the same extent
and in the same manner as such Indebtedness is subordinated to such other
Indebtedness of the Company or such Guarantor, as the case may be.

Section 3.03.  Limitations on Restricted Payments.
               ----------------------------------

          (a)  Until the Notes are rated Investment Grade by both Rating
Agencies (after which time the following covenant will no longer be in effect),
the Company will not, and will not cause or permit any Restricted Subsidiary to,
directly or indirectly, make any Restricted Payment unless:

               i)    no Default or Event of Default shall have occurred and be
continuing at the time of or immediately after giving effect to such Restricted
Payment;

               ii)   immediately after giving effect to such Restricted Payment,
the Company could incur at least $1.00 of Indebtedness pursuant to Section
3.02(a) hereof; and

               iii)  immediately after giving effect to such Restricted Payment,
the aggregate amount of all Restricted Payments (including the Fair Market Value
of any non-cash Restricted Payment) declared or made after the Issue Date does
not exceed the sum of (a) 50% of the Consolidated Net Income of the Company on a
cumulative basis during the period (taken as one accounting period) from and
including February 1, 1999 and ending on the last day of the Company's fiscal
quarter immediately preceding the date of such Restricted Payment (or in the
event such Consolidated Net Income shall be a deficit, minus
<PAGE>
 
                                      -28-

100% of such deficit), plus (b) 100% of the aggregate net cash proceeds of and
the fair market value of Property received by the Company from (1) any capital
contribution to the Company after June 9, 1997 or any issue or sale after June
9, 1997 of Qualified Stock (other than to any Subsidiary of the Company) and (2)
the issue or sale after June 9, 1997 of any Indebtedness or other securities of
the Company convertible into or exercisable for Qualified Stock of the Company
that have been so converted or exercised, as the case may be, plus (c) $86.0
million, which is equal to the aggregate principal amount of the Company's 6-
7/8% Convertible Subordinated Notes due 2002 that were converted into the
Company's Common Equity prior to the Issue Date, plus (d) in the case of the
disposition or repayment of any Investment constituting a Restricted Payment
made after the June 9, 1997, an amount (to the extent not included in the
calculation of the Consolidated Net Income referred to in (a)) equal to the
lesser of (x) the return of capital with respect to such Investment (including
by dividend, distribution or sale of Capital Stock) and (y) the amount of such
Investment that was treated as a Restricted Payment, in either case, less the
cost of the disposition or repayment of such Investment (to the extent not
included in the calculation of the Consolidated Net Income referred to in (a)),
plus (e) with respect to any Unrestricted Subsidiary that is redesignated as a
Restricted Subsidiary after June 9, 1997 in accordance with the definition of
Unrestricted Subsidiary (so long as the designation of such Subsidiary as an
Unrestricted Subsidiary was treated as a Restricted Payment made after June 9,
1997 and only to the extent not included in the calculation of the Consolidated
Net Income referred to in (a)), an amount equal to the lesser of (x) the
proportionate interest of the Company or a Restricted Subsidiary in an amount
equal to the excess of (I) the total assets of such Subsidiary, valued on an
aggregate basis at the lesser of book value and Fair Market Value thereof, over
(II) the total liabilities of such Subsidiary, determined in accordance with
GAAP, and (y) the Designation Amount at the time of such Subsidiary's
designation as an Unrestricted Subsidiary, plus (f) $25 million minus (g) the
aggregate amount of all Restricted Payments (other than Restricted Payments
referred to in clause (C) of the immediately succeeding paragraph) made after
June 9, 1997 through the Issue Date.

          (b)  Clauses (ii) and (iii) of paragraph (a) will not prohibit: (A)
the payment of any dividend within 60 days of its declaration if such dividend
could have been made on the date of its declaration without violation of the
provisions of this Indenture; (B) the repurchase, redemption or retirement of
any shares of Capital Stock of the Company in exchange for, or out
<PAGE>
 
                                      -29-

of the net proceeds of the substantially concurrent sale (other than to a
Subsidiary of the Company) of, other shares of Qualified Stock; and (C) the
purchase, redemption or other acquisition, cancellation or retirement for value
of Capital Stock, or options, warrants, equity appreciation rights or other
rights to purchase or acquire Capital Stock, of the Company or any Subsidiary
held by officers or employees or former officers or employees of the Company or
any Subsidiary (or their estates or beneficiaries under their estates) not to
exceed $20 million in the aggregate since the Issue Date; provided, however,
that each Restricted Payment described in clauses (A) and (B) of this sentence
shall be taken into account for purposes of computing the aggregate amount of
all Restricted Payments pursuant to clause (iii) of paragraph (a).

          (c)  For purposes of determining the aggregate and permitted amounts
of Restricted Payments made, the amount of any guarantee of any Investment in
any Person that was initially treated as a Restricted Payment and which was
subsequently terminated or expired, net of any amounts paid by the Company or
any Restricted Subsidiary in respect of such guarantee, shall be deducted.

          (d)  In determining the "fair market value of Property" for purposes
of clause (iii) of the paragraph (a), Property other than cash, Cash Equivalents
and Marketable Securities shall be deemed to be equal in value to the "equity
value" of the Capital Stock or other securities issued in exchange therefor.
The "equity value" of such Capital Stock or other securities shall be equal to
(i) the number of shares of Common Equity issued in the transaction (or issuable
upon conversion or exercise of the Capital Stock or other securities issued in
the transaction) multiplied by the closing sale price of the Common Equity on
its principal market on the date of the transaction (less, in the case of
Capital Stock or other securities which require the payment of consideration at
the time of conversion or exercise, the aggregate consideration payable
thereupon) or (ii) if the Common Equity is not then traded on the New York Stock
Exchange, American Stock Exchange or Nasdaq National Market, or if the Capital
Stock or other securities issued in the transaction do not consist of Common
Equity (or Capital Stock or other securities convertible into or exercisable for
Common Equity), the value of such Capital Stock or other securities as
determined by a nationally recognized investment banking firm retained by the
Board of Directors of the Company.

Section 3.04.  Limitations on Transactions with Affiliates.
               -------------------------------------------

          (a)  Until the Notes are rated Investment Grade by both Rating
Agencies (after which time the following covenant will no longer be in effect),
the Company will not, and will not cause or permit any Restricted Subsidiary to,
make any loan, advance, guarantee or capital contribution to, or for the benefit
of, or sell, lease, transfer or otherwise dispose of any property or assets to,
or for the benefit of, or purchase or lease any property or assets from, or
enter into or amend any contract, agreement or understanding with, or for the
benefit of, any Affiliate of the Company or any Affiliate of any of the
Company's Subsidiaries or any holder of 10% or more of the Common Equity of the
Company (including any Affiliates of such holders), in a single transaction or
series of related transactions (each, an "Affiliate Transaction"), except for
                                          ---------------------              
any Affiliate Transaction the terms of which are at least as favorable as the
terms which could be obtained by the Company or such Restricted Subsidiary, as
the case may be, in a comparable transaction made on an arm's length basis with
Persons who are not such a holder, an Affiliate of such a holder or an Affiliate
of the Company or any of the Company's Subsidiaries.

          (b)  In addition, the Company will not, and will not cause or permit
any Restricted Subsidiary to, enter into an Affiliate Transaction unless (i)
with respect to any such Affiliate Transaction involving or having a value of
more than $5 million, the Company shall have (x) obtained the approval of a
majority of the Board of Directors of the Company and (y) either obtained the
approval of a majority of the Company's disinterested directors or obtained an
opinion of a qualified independent financial advisor to the effect that such
Affiliate Transaction is fair to the Company or such Restricted Subsidiary, as
the case may be, from a financial point of view and (ii) with respect to any
such Affiliate Transaction involving or having a value of more than $25 million,
the Company shall have (x) obtained the approval of a majority of the Board of
Directors of the Company and (y) delivered to the Trustee an opinion of a
qualified independent financial advisor to the effect that such Affiliate
Transaction is fair to the Company or such Restricted Subsidiary, as the case
may be, from a financial point of view.

          (c)  Notwithstanding the foregoing, an Affiliate Transaction will not
include (i) any contract, agreement or understanding with, or for the benefit
of, or plan for the benefit of employees of the Company or its Subsidiaries
generally
<PAGE>
 
                                      -31-

(in their capacities as such) that has been approved by the Board of Directors
of the Company, (ii) Capital Stock issuances to directors, officers and
employees of the Company or its Subsidiaries pursuant to plans approved by the
stockholders of the Company, (iii) any Restricted Payment otherwise permitted
under the "Limitations on Restricted Payments" covenant, (iv) any transaction
between or among the Company and one or more Restricted Subsidiaries or between
or among Restricted Subsidiaries (provided, however, no such transaction shall
                                  --------  -------
involve any other Affiliate of the Company (other than an Unrestricted
Subsidiary to the extent the applicable amount constitutes a Restricted Payment
permitted by this Indenture)) and (v) any transaction between one or more
Restricted Subsidiaries and one or more Unrestricted Subsidiaries where all of
the payments to, or other benefits conferred upon, such Unrestricted
Subsidiaries are substantially contemporaneously dividended, or otherwise
distributed or transferred without charge, to the Company or a Restricted
Subsidiary.

Section 3.05.  Limitations on Dispositions of Assets.
               -------------------------------------

          Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary to,
make any Asset Disposition unless (x) the Company (or such Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset
Disposition at least equal to the Fair Market Value thereof, and (y) not less
than 70% of the consideration received by the Company (or such Restricted
Subsidiary, as the case may be) is in the form of cash, Cash Equivalents and
Marketable Securities.  The amount of any Indebtedness (other than any
Indebtedness subordinated to the Notes) of the Company or any Restricted
Subsidiary that is actually assumed by the transferee in such Asset Disposition
shall be deemed to be consideration required by clause (y) above for purposes of
determining the percentage of such consideration received by the Company or the
Restricted Subsidiaries.  The Net Cash Proceeds of an Asset Disposition shall,
within one year, at the Company's election, (a) be used by the Company or a
Restricted Subsidiary in the business of the construction and sale of homes
conducted by the Company and the Restricted Subsidiaries or any other business
of the Company or a Restricted Subsidiary existing at the time of such Asset
Disposition or (b) to the extent not so used, be applied to make a Net Cash
Proceeds Offer for the Notes and, if the Company or a Restricted Subsidiary
elects or is required to do so, repay, purchase or redeem any other
unsubordinated Indebtedness (on a pro rata basis if
<PAGE>
 
                                      -32-

the amount available for such repayment, purchase or redemption is less than the
aggregate amount of (i) the principal amount of the Notes tendered in such Net
Cash Proceeds Offer and (ii) the lesser of the principal amount, or accreted
value, of such other unsubordinated Indebtedness, plus, in each case accrued
interest to the date of repayment, purchase or redemption) at 100% of the
principal amount or accreted value thereof, as the case may be, plus accrued
interest to the date of repurchase or repayment. Notwithstanding the foregoing,
(A) the Company will not be required to apply such Net Cash Proceeds to the
repurchase of Notes in accordance with clause (b) of the preceding sentence
except to the extent that such Net Cash Proceeds, together with the aggregate
Net Cash Proceeds of prior Asset Dispositions (other than those so used) which
have not been applied in accordance with this provision and as to which no prior
Net Cash Proceeds Offer shall have been made, exceed 5% of Consolidated Tangible
Assets and (B) in connection with any Asset Disposition, the Company and the
Restricted Subsidiaries will not be required to comply with the requirements of
clause (y) of the first sentence of this paragraph to the extent that the
aggregate non-cash consideration received in connection with such Asset
Disposition, together with the sum of all non-cash consideration received in
connection with all prior Asset Dispositions that has not yet been converted
into cash, does not exceed 5% of Consolidated Tangible Assets; provided,
                                                               --------
however, that when any non-cash consideration is converted into cash, such cash
- -------
shall constitute Net Cash Proceeds and be subject to the preceding sentence.

Section 3.06.  Limitations on Liens.
               --------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, incur, assume or suffer to exist any Liens, other than
Permitted Liens, on any of its Property, or on any shares of Capital Stock or
Indebtedness of any Restricted Subsidiary, unless contemporaneously therewith or
prior thereto all payments due under this Indenture and the Notes are secured on
an equal and ratable basis with the obligation or liability so secured until
such time as such obligation or liability is no longer secured by a Lien.

Section 3.07.  Limitations on Restrictions Affecting Restricted Subsidiaries.
               -------------------------------------------------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, assume or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction (other than encumbrances or
restrictions
<PAGE>
 
                                      -33-

imposed by law or by judicial or regulatory action or by provisions of leases
and other agreements that restrict the assignability thereof) on the ability of
any Restricted Subsidiary to (i) pay dividends or make any other distributions
on its Capital Stock or any other interest or participation in, or measured by,
its profits, owned by the Company or any other Restricted Subsidiary, or pay
interest on or principal of any Indebtedness owed to the Company or any other
Restricted Subsidiary, (ii) make loans or advances to the Company or any other
Restricted Subsidiary, or (iii) transfer any of its properties or assets to the
Company or any other Restricted Subsidiary, except for (a) encumbrances or
restrictions existing under or by reason of applicable law, (b) covenants or
restrictions contained in Indebtedness in effect on the date of this Indenture
as such covenants or restrictions are in effect on such date, (c) any
restrictions or encumbrances arising under Acquired Indebtedness; provided, that
                                                                  --------
such encumbrance or restriction applies only to either the assets that were
subject to the restriction or encumbrance at the time of the acquisition or the
obligor on such Indebtedness and its Subsidiaries, (d) any restrictions or
encumbrances arising in connection with Refinancing Indebtedness; provided,
                                                                  --------
however, that any restrictions and encumbrances of the type described in this
- -------
clause (d) that arise under such Refinancing Indebtedness shall not be
materially more restrictive than those under the agreement creating or
evidencing the Indebtedness being refunded, refinanced, replaced or extended,
(e) any Permitted Lien, or any other agreement restricting the sale or other
disposition of property, securing Indebtedness permitted by this Indenture if
such Permitted Lien or agreement does not expressly restrict the ability of a
Subsidiary of the Company to pay dividends or make or repay loans or advances
prior to default thereunder, (f) reasonable and customary borrowing base
covenants set forth in agreements evidencing Indebtedness otherwise permitted by
this Indenture, (g) customary provisions restricting subletting or assignment of

limitation, by way of liquidation or dissolution), or assign any of its

substantially in one transaction or in a series of related transactions), to any
Person (in each case other than in a transaction in which the Company or a
Restricted Subsidiary is the survivor of a consolidation or merger, or the
transferee in a sale, lease, conveyance or other disposition) unless: (i) the
Person formed by or surviving such consolidation or merger (if other than the
Company or the Guarantor, as the case may be), or to which such sale, lease,
conveyance or other disposition or assignment will be made (collectively, the
"Successor"), is a corporation or other legal entity organized and existing
 ---------
under the laws of the United States or any state thereof or the District of
Columbia, and the Successor assumes by supplemental indenture in a form

Company immediately prior to such transaction (exclusive of any adjustments to
Consolidated Net Worth attributable to transaction costs) less any amount
treated as a Restricted Payment in connection with such transaction in
accordance with this Indenture and (iv) unless prior to such transaction the
Notes are rated Investment Grade by both Rating Agencies (after which this
clause (iv) shall not apply), immediately after giving effect to such
transaction, the Company could incur at least $1.00 of Indebtedness pursuant to
Section 3.02(a) hereof. The foregoing provisions shall not apply to (i) a
transaction involving the sale or disposition of Capital Stock of a Guarantor,

other disposition of all or substantially all of the assets of a Guarantor, that
in any such case results in such Guarantor being released from its Guarantee

Section 3.09.  Reports to Holders of Notes.
               ---------------------------

information, documents and other reports required to be filed pursuant to
Section 13 or 15(d) of the Exchange Act.  The Company will file with the Trustee
and mail to each Holder of record of Notes such reports, information and
documents within 15 days after it files them with the Commission.  In the event
that the Company is no longer subject to these periodic requirements of the
Exchange Act, it will nonetheless continue to file reports with the Commission
and the Trustee and mail such reports to each holder of Notes as if it were
subject to such reporting requirements.  Regardless of whether the Company is
required to furnish such reports to its stockholders pursuant to the Exchange
Act, the Company will cause its consolidated financial statements and a
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" written report, similar to those that would have been required to
appear in annual or quarterly reports, to be delivered to Holders of Notes.

                           8% Senior Notes due 2009

1.  Interest.
    -------- 

          D.R. HORTON, INC. (the "Company"), a Delaware corporation, promises to
pay interest on the principal amount of this Security at the rate per annum
shown above.  The Company will pay interest semiannually on February 1 and
August 1 of each year, commencing August 1, 1999, until the principal is paid or
made available for payment.  Interest on the Securities will accrue from the
most recent date to which interest has been paid or duly provided for or, if no
interest has been paid, from the date of original issuance, provided that, if
there is no existing default in the payment of interest, and if this Security is
authenticated between a record date referred to on the face hereof and the next
succeeding interest payment date, interest shall accrue from such interest
payment date.  Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

2.  Method of Payment.
    ----------------- 

          The Company will pay interest on the Securities (except defaulted
interest, if any, which will be paid on such special payment date to Holders of
record on such special record date as may be fixed by the Company) to the
persons who are registered Holders of Securities at the close of business on the
January 15 and July 15 immediately preceding the interest payment date.  Holders
must surrender Securities to a Paying Agent to collect principal payments.  The
Company will pay principal and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts.

3.  Paying Agent and Registrar.
    -------------------------- 

          Initially, American Stock Transfer & Trust Company (the "Trustee")
will act as Paying Agent and Registrar.  The Company may change or appoint any
Paying Agent, Registrar or co-Registrar without notice.  The Company or any of
its Subsidiaries may act as Paying Agent, Registrar or co-Registrar.

4.  Indenture.
    --------- 

          The Company issued the Securities under an Indenture dated as of June
9, 1997 among the Company, the Guarantors and the Trustee, as supplemented (the
"Indenture").  The terms of the Securities and the Guarantees include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 ("TIA") as in effect on the date of the Indenture.
The Securities and the Guarantees are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
them.  Capitalized terms not defined herein have the meanings given to those
terms in the Indenture.

          The Company will furnish to any Securityholder upon written request
and without charge a copy of the Indenture and the applicable Authorizing
Resolution or supplemental indenture.  Requests may be made to:  D.R. Horton,
Inc., 1901 Ascension Blvd., Suite 100, Arlington, Texas 76006, Attention:  Chief
Financial Officer.

5.  Redemption.
    ---------- 

          Except as set forth in the following sentence, the Securities will not
be redeemable.  The Company may redeem Securities, at any time prior to February
1, 2002, with the net cash proceeds of one or more Public Equity Offerings by
the Company, at a redemption price equal to 108.0% of the principal amount of
such Securities, plus accrued and unpaid interest, if any, to the date of
redemption; provided, however, that after each such redemption not less than
            --------  -------                                               
$250,300,000 principal amount of Securities (including any Additional Securities
but excluding any Securities held by the Company or any of its Affiliates)
remains outstanding.  Notice of any such redemption must be given within 60 days
after the date of the closing of the relevant Public Equity Offering.

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Securities to be redeemed
at his registered address.  Securities in denominations larger than $1,000 may
be redeemed in part.  On and after the redemption date interest ceases to accrue
on Securities or portions of them called for redemption, provided that if the
Company shall default in the payment of such Security at the redemption price
together with accrued in-



                                      A-4
<PAGE>
 
terest, interest shall continue to accrue at the rate borne by the Securities.

6.  Denominations, Transfer, Exchange.
    --------------------------------- 

          The Securities are in registered form only without coupons in
denominations of $1,000 and integral multiples of $1,000.  A Holder may transfer
or exchange Securities by presentation of such Securities to the Registrar or a
co-Registrar with a request to register the transfer or to exchange them for an
equal principal amount of Securities of other denominations.  The Registrar may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not transfer or exchange any Security
selected for redemption, except the unredeemed part thereof if the Security is
redeemed in part, or transfer or exchange any Securities for a period of 15 days
before a selection of Securities to be redeemed.

7.  Persons Deemed Owners.
    --------------------- 

          The registered Holder of this Security shall be treated as the owner
of it for all purposes.

8.  Unclaimed Money.
    --------------- 

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent will pay the money back to the
Company at its request.  After that, Holders entitled to the money must look to
the Company for payment unless an abandoned property law designates another
person.

9.  Amendment, Supplement, Waiver.
    ----------------------------- 

          Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of at least a majority
in principal amount of the outstanding Securities and any past default or
compliance with any provision relating to the Securities may be waived in a
particular instance with the consent of the Holders of a majority in principal
amount of the outstanding Securities.  Without the consent of any
Securityholder, the Company and the Trustee may amend or supplement the
Indenture or the Securities to cure any ambiguity, defect or inconsistency, to
provide for uncerti-

ficated Securities in addition to or in place of certificated Securities, to
create a Series and establish its terms, to remove a Guarantor which, in
accordance with the terms of the Indenture, ceases to be liable in respect of
its Guarantee, or to make any other change, provided such action does not
adversely affect the rights of any Securityholder.

10.  Successor Corporation.
     --------------------- 

          When a successor corporation assumes all the obligations of its
predecessor under the Securities and the Indenture, the predecessor corporation
will be released from those obligations.

11.  Trustee Dealings With Company.
     ----------------------------- 

          American Stock Transfer & Trust Company, the Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may
otherwise deal with the Company or its affiliates, as if it were not Trustee.

12.  No Recourse Against Others.
     -------------------------- 

          A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of, such obligations or their creation.  Each Securityholder by accepting
a Security waives and releases all such liability.  The waiver and release are
part of the consideration for the issue of the Securities.

13.  Discharge of Indenture.
     ---------------------- 

          The Indenture contains certain provisions pertaining to defeasance,
which provisions shall for all purposes have the same effect as if set forth
herein.

14.  Authentication.
     -------------- 

          This Security shall not be valid until the Trustee signs the
certificate of authentication on the other side of this Security.

          The undersigned (the "Guarantors") have unconditionally guaranteed,
jointly and severally (such guarantee by each Guarantor being referred to herein
as the "Guarantee") (i) the due and punctual payment of the principal of and
interest on the Securities, whether at maturity, by acceleration or otherwise,
the due and punctual payment of interest on the overdue principal and interest,
if any, on the Securities, to the extent lawful, and the due and punctual
performance of all other obligations of the Company to the Holders or the
Trustee all in accordance with the terms set forth in Article Nine of the
Indenture and (ii) in case of any extension of time of payment or renewal of any
Securities or any of such other obligations, that the same will be promptly paid
in full when due or performed in accordance with the terms of the extension or
renewal, whether at stated maturity, by acceleration or otherwise.

          No past, present or future stockholder, officer, director, employee or
incorporator, as such, of any of the Guarantors shall have any liability under
the Guarantee by reason of such person's status as stockholder, officer,
director, employee or incorporator.  Each holder of a Security by accepting a
Security waives and releases all such liability.  This waiver and release are
part of the consideration for the issuance of the Guarantees.

          Each holder of a Security by accepting a Security agrees that any
Guarantor named below shall have no further liability with respect to its
Guarantee if such Guarantor otherwise ceases to be liable in respect of its
Guarantee in accordance with the terms of the Indenture.

          The Guarantee shall not be valid or obligatory for any purpose until
the certificate of authentication on the Securities upon which the Guarantee is
noted shall have been executed by the Trustee under the Indenture by the manual
signature of one of its authorized officers.
