                           ------------

                     (iii) an additional $30,000 in cash to be paid if and only
                           if the conditions set forth in Section 1.06 have been

         Effective Time will by virtue of the Merger and at the Effective Time,
         and without further action on the part of any holder thereof, be
         converted into the right to receive the Merger Consideration, subject
         to all terms and conditions of this Agreement, including, without

         1.02  Fractional Shares. No fractional shares of Edge Common Stock will
               -----------------
be issued in connection with the Merger, but in lieu thereof, the holder of any
shares of Media Resolutions Common Stock who would otherwise be entitled to
receive a fraction of a share of Edge Common Stock would receive from Edge,
promptly after the Effective Time, an amount of cash equal to $0.753 multiplied
by the fraction of a share of Edge Common Stock to which such holder would
otherwise be entitled.

         1.03  Withheld Merger Consideration.  At the Closing, Edge shall retain
               -----------------------------

         an amount not to exceed $75,000, any of the following amounts upon
         delivery of a notice to Media Resolutions and the accompanying

                     (i)   any Media Resolutions Pre-Closing Date Tax
                           Obligations, as defined in Section 2.08(b), that
                           remain unpaid as of the Closing Date;

                           in excess of $10,000.

               (c)   On the date that is six months and one day after the
         Effective Date, Edge shall release $75,000 of the Withheld Merger
         Consideration to the Media Resolutions Shareholders; provided, that on
         such date there are no current, pending or threatened Claims for
         indemnification under Section 6.02 that would exceed, in the aggregate,
         $75,000.

               (d)   Edge shall release any remaining amounts of Withheld Merger
         Consideration to the Media Resolutions Shareholders on the date that is
         twelve months and one day from the Effective Date; provided, however,
                                                            --------  -------
         that on such date there are current, pending or threatened Claims
         ("Current Claims") for indemnification under Section 6.02, then Edge
         shall not release any amounts (the "Holdback") which Edge believes in
         good faith may be required to satisfy such Current Claims. Edge shall
         release the remaining balance of the Holdback within three (3) business
         days after the date that all Current Claims are finally resolved.

               (e)   If all or a portion of any payment to be made pursuant to
         Sections 1.03(c) and 1.03(d) has not be paid when due, then any and all
         amounts payable due and payable at such time under this Agreement by
         Edge shall thereafter bear interest at a rate per annum equal to 12%
         until such overdue amount is paid in full. In addition thereto, Edge's
         obligations to make payment to the Media Resolutions Shareholders under
         Sections 1.03(c) and 1.03(d) shall be secured by a stock pledge, the
         form of which is attached hereto as Exhibit B.
                                             ---------

               (f)   The deductions against the Withheld Merger Consideration
         set forth in this Section 1.03 shall not be deemed to be Edge's
         exclusive remedy for any breach by Media Resolutions or any Media
         Resolutions Shareholder of any term, condition, provision, or
         obligation hereunder.

         1.04  Effects of the Merger.  At the Effective Time:
               ---------------------

               (a)   the separate existence of Acquisition Corp. will cease

         terms of the Plan of Merger;

               (b)   the Articles of Incorporation and Bylaws of Acquisition

              (f)  the Merger will, at and after the Effective Time, have all of
         the effects  provided by applicable law.

         1.05 Further Assurances.  Media Resolutions agrees that if, at any time
              ------------------
after the Effective Time, Edge considers or is advised that any further deeds,
assignments or assurances are reasonably necessary or desirable to vest, perfect
or confirm in the Surviving Corporation title to any property or rights of Media
Resolutions, Edge and any of its officers are hereby authorized by Media
Resolutions to execute and deliver all such proper deeds, assignments and
assurances and do all other things reasonably necessary or desirable to vest,
perfect or confirm title to such property or rights in the Surviving Corporation
and otherwise to carry out the purposes of this Agreement, in the name of Media
Resolutions or otherwise.

         1.06 Earnout Commissions.
              -------------------

              (a) In the event that "RadCart Gross Revenue" (as defined below)
         during the period beginning on the Closing Date and continuing until
         the date that is twelve months after the Closing Date (the "Earnout
         Period") equals to or exceeds $60,000, then Edge shall make an earnout
         payment in the amount of $30,000 (the "Earnout Commission"), to the
         Media Resolutions Shareholders as set forth below.

              (b) For purposes of this Agreement, the term "RadCart Gross
         Revenue" shall mean an amount equal to the gross revenue actually
         received by the Surviving Corporation during the Earnout Period from
         the sale of, or provision of services related to, the RadCart web site
         shopping cart, whether in the form of a PC or PDA based shopping cart,
         including, but not limited to proceeds from any licenses granted or
         royalties received in connection with such products and services.

              (c) Edge shall pay to the Media Resolutions Shareholders an amount
         in cash equal to the Earnout Commission earned, if any, by the later of
         (i) sixty (60) days following the end of the Earnout Period or (ii) the
         final determination of the RadCart Gross Revenue.

              (d) As promptly as practicable, but in no event later than thirty
         (30) days after the end of the Earnout Period, Edge shall deliver to
         the Media Resolutions Shareholders a calculation of RadCart Gross
         Revenue. Media Resolution Shareholders shall, at their own expense,
         have an opportunity to audit the calculation and such audit shall be
         the final determination of said RadCart Gross Revenue.

         1.07 Incidental Registration (a) If at any time after the date hereof
              -----------------------
but before the fifth anniversary of the date hereof, Edge proposes to register
any of its common stock under the Securities Act of 1933 (the "Securities Act")
(other than by a registration in connection with an acquisition in a manner
which would not permit registration of the common stock for sale to the public,
on Form S-8, or any successor form thereto, on Form S-4, or any successor form
thereto), on an underwritten basis (either best-efforts or firm-commitment),
then, Edge will each such time give prompt written notice to each of the Media
Resolutions Shareholders of its intention to do so and of such Media Resolutions
Shareholder's rights under this Section 1.07. Upon the written request of any
such Media Resolutions Shareholder made within ten (10) days

AGREEMENT AND PLAN OF MERGER - Page 5

<PAGE>

after the receipt of any such notice (which request shall specify the Edge
Common Stock intended to be disposed of by such Holder), Edge will, subject to
the terms of this Agreement, effect the registration under the Securities Act of
the requested Edge Common Stock, to the extent requisite to permit the
disposition of such Edge Common Stock so to be registered, by inclusion of such
Edge Common Stock in the registration statement which covers the securities
which Edge proposes to register, provided that if, at any time after giving
written notice of its intention to register any securities and prior to the
effective date of the registration statement filed in connection with such
registration, Edge shall determine for any reason either not to register or to
delay registration of such securities, Edge may, at its election, give written
notice of such determination to each Media Resolutions Shareholder and,
thereupon, (i) in the case of a determination not to register, shall be relieved
of its obligation to register any Edge Common Stock in connection with such
registration (but not from its obligation to pay the reasonable registration
expenses in connection therewith), and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering any Edge Common
Stock, for the same period as the delay in registering such other common stock
of Edge. Edge will pay all registration expenses in connection with each
registration of Edge Common Stock requested pursuant to this Section 1.07.

         (b) If the managing underwriter of the underwritten offering
contemplated by this Section 1.07 shall inform Edge and the Media Resolutions
Shareholders requesting registration of the Edge Common Stock by letter of its
belief that the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering, then Edge
will include in such registration, to the extent of the number which Edge is so
advised can be sold in such offering, (i) first securities proposed by Edge to
be sold for its own account, and (ii) second Edge Common Stock and securities of
other selling security holders requested to be included in such registration pro
rata on the basis of the number of shares of such securities so proposed to be
sold and so requested to be included; provided, however, the holders of Edge
Common Stock shall have priority to all shares sought to be included by officers
and directors of Edge as well as holders of ten percent (10%) or more of the
common stock of Edge unless the holders of such shares are exercising their own
registration rights.

     4.05 No Violation of Existing Agreements. Neither the execution and
          -----------------------------------
delivery of this Agreement or any agreement executed by Edge in connection with
the delivery of this Agreement, nor the consummation of the transactions

          ---------------------------------------------

                                 CLOSING MATTERS

     5.01 The Closing. The closing of this Agreement and the transactions
          -----------
contemplated hereunder (the "Closing") shall take place contemporaneously with
the execution hereof and on the date hereof (the "Closing Date") but for all

AGREEMENT AND PLAN OF MERGER - Page 23

<PAGE>

and such other documents as may be required to effectuate the Merger will be
filed in the office of the Secretary of State of the State of Texas, and the
Merger will become effective at the Effective Time.

     5.02 Exchange of Certificates.
          ------------------------

          (a) As of the Effective Time, all shares of Media Resolutions Common
     Stock that are outstanding immediately prior thereto will, by virtue of the
     Merger and without further action, cease to exist, and each share of Media
     Resolutions Common Stock will be converted into the right to receive from
     Edge that portion of the Merger Consideration, subject to the withholding
     provisions of Section 1.03, that each such share bears to the total of all
     shares of Media Resolutions Common Stock issued and outstanding as of the
     Effective Time (the "Pro Rata Portion").

          (b) At and after the Effective Time, each certificate representing
     outstanding shares of Media Resolutions Common Stock will represent the
     number of shares of Edge Common Stock into which such shares of Media
     Resolutions Common Stock have been converted, and such shares of Edge
     Common Stock will be deemed registered in the name of the holder of such
     certificate. Upon the Effective Time, the holder of shares of Media
     Resolutions Common Stock will surrender (i) the certificates of such shares
     (the "Media Resolutions Certificates") to Edge for cancellation or (ii) an
           ------------------------------
     affidavit of lost (or non-issued) certificate and agreement to indemnify in
     form satisfactory to Edge (an "Affidavit"). Further, all rights to acquire
                                    ---------
     capital stock of Media Resolutions (whether in the form of options,
     warrants, or rights to convert securities) shall be terminated upon the
     Effective Time, such that upon the payment of the Merger Consideration,
     Edge will hold 100% of the capital stock of Media Resolutions and no rights
     or options to purchase or receive any shares of Media Resolutions' capital
     stock shall be outstanding. At Closing, Edge will deliver such Holder's Pro
     Rata Portion of the Cash Consideration less the amount withheld pursuant to
     Section 1.03 and as soon as practicable after the Effective Time and
     receipt of Media Resolutions Certificates and of any Affidavits, will issue
     to such surrendering holder certificate(s) representing such holder's Pro
     Rata Portion of the Stock Consideration and any cash for fractional shares
     payable under Section 1.02.

          (c) All shares of Edge Common Stock (and, if applicable, cash in lieu
     of fractional shares) delivered upon the surrender of Media Resolutions
     Certificates in accordance with the terms hereof will be delivered to the
     registered holder. After the Effective Time, there will be no further
     registration of transfers of the shares of Media Resolutions Common Stock
     on the stock transfer books of Media Resolutions. If, after the Effective
     Time, Media Resolutions Certificates are presented for transfer or for any
     other reason, they will be canceled and exchanged and certificates for Edge
     Common Stock will be delivered pursuant to the terms and conditions set
     forth in this Section 5.02.

          (d) Until certificates representing Media Resolutions Common Stock
     outstanding prior to the Merger are surrendered pursuant to Section 5.02
     (b) above, such certificates will be deemed, for all purposes, to evidence
     ownership of (i) the number of shares of Edge Common Stock into which the
     shares of Media Resolutions Common

AGREEMENT AND PLAN OF MERGER - Page 24

<PAGE>

          Stock will have been converted, subject to the obligation to withhold
          a portion thereof as required hereby, and (ii) if applicable, cash in
          lieu of fractional shares.

          5.03    Delivery of Lease Agreement. At the Closing, Media Resolutions
                  ---------------------------
shall deliver to Edge an executed lease agreement between Media Resolutions and
Allegiance Telecom, upon terms and conditions that are acceptable to Edge, in
the exercise of its sole discretion, including, without limitation, a lease term
expiring not less than six months from the Closing Date.

         to individually as an "Indemnified Person" and collectively as
                                ------------------
         "Indemnified Persons") from and against any and all claims, demands,

         actions, causes of action, losses, costs, damages, liabilities and

     instrument delivered by or on behalf of Media Resolutions and/or by the
     Media Resolutions Shareholders pursuant hereto (hereafter in this Section
     6.02 referred to as the "Edge Damages"); provided; however, that in no
                              ------------    --------  -------
     event shall the aggregate liability of the Media Resolutions Shareholders
     under this Agreement exceed an amount greater than $730,000.

       (b) Withheld Merger Consideration. Except for the Adjustment Amounts set
           -----------------------------
     forth in Section 1.03(a)(i) and (iii) above, Indemnified Persons shall make
     no deductions in the Withheld Merger Consideration and shall have no claims
     against the Media Resolutions Shareholders unless and until the Edge
     Damages exceed $10,000, (the "Threshold Amount"), at which point the
     Indemnified Persons shall be entitled to indemnification for all claims,
     including those within the Threshold Amount. In seeking indemnification for
     Edge Damages under this Section 6.02 following the Closing, the Indemnified
     Persons shall be entitled to, including, without limitation, available
     amounts of the Withheld Merger Consideration and all other remedies
     available at law or in equity.

     Promptly after the receipt by Edge of notice or discovery of any claim,
     damage or legal action or proceeding giving rise to indemnification rights
     under this Section 6.02, Edge will give the Claims Representative written
     notice of such claim, damage, legal action or proceeding (for purposes of
     this Section 6.02, a "Claim") in accordance with Section 6.02 of this
     Agreement. Within seven days of delivery of such written notice, the Claims
     Representative may, with Edge's written consent, which shall not be
     unreasonably withheld, at the expense of the Media Resolutions
     Shareholders, elect to take all necessary steps properly to contest any
     Claim involving third parties or to prosecute or defend such Claim to
     conclusion or settlement. If the Claims Representative makes the foregoing
     election, then the Claims Representative will take all necessary steps to
     contest any such Claim or to prosecute or defend such Claim to conclusion
     or settlement, and will notify Edge of the progress of any such Claim, will
     permit Edge, at its expense, to participate in such prosecution or defense
     (PROVIDED, HOWEVER, that if a conflict of interest exists which would make
     it inappropriate, in the reasonable opinion of Edge, for the same counsel
     to represent both Edge and the Media Resolutions Shareholders in the
     resolution of such Claim, then Edge may retain separate counsel, the fees
     and expenses of which shall not be borne by Edge but shall instead be borne
     by the Media Resolutions Shareholders) and will provide Edge with
     reasonable access to all relevant information and documents relating to the
     Claim and the Claims Representative's prosecution or defense thereof. If
     the Claims Representative does not make such election, then Edge shall be
     free to handle the prosecution or defense of any such Claim, will take all
     necessary steps to contest any such Claim involving third parties or to
     prosecute or defend such Claim to conclusion or settlement, will notify the
     Claims Representative of the progress of any such Claim, and will permit
     the Claims Representative, at the expense of the Media Resolutions
     Shareholders (which expense shall be paid for from sources other than the
     Withheld Merger Consideration) to participate in such prosecution or
     defense and will provide the Claims Representative with reasonable access
     to all relevant information and documents

AGREEMENT AND PLAN OF MERGER - Page 26

<PAGE>

     relating to the Claim and Edge's prosecution or defense thereof. In either
     case, the party not in control of a Claim will fully cooperate, and will
     cause its counsel, if any, to fully cooperate, with the other party in the
     conduct of the prosecution or defense of such Claim. Neither party will
     compromise or settle any such Claim without the written consent of either
     Edge (if the Claims Representative defends the Claim) or the Claims
     Representative (if Edge defends the Claim), such consent not to be
     unreasonably withheld.

          (d) Any written notice of a Claim required under this Section 6.02
     (for purposes of this Section 6.02, a "Notice of Claim") will be in writing
     and will contain the following information to the extent reasonably
     available to Edge:

              (1) Edge's good faith estimate of the reasonably foreseeable
          maximum amount of the alleged Edge Damages (which amount may be the
          amount of damages claimed by a third party plaintiff in an action
          brought against Edge or Media Resolutions); and

              (2) A brief description in reasonable detail of the facts,
          circumstances or events giving rise to the alleged Edge Damages based
          on Edge's good faith belief thereof and the basis under this Agreement
          for such Claim, including, without limitation, the identity and
          address of any third-party claimant (to the extent reasonably
          available to Edge) and copies of any formal demand or complaint.

          (e) For purposes of Sections 6.02 and 6.03, the Media Resolutions
     Shareholders hereby consent to the appointment of the Claims
     Representative, as representative of the Media Resolutions Shareholders,
     and as the attorney-in-fact for and on behalf of each Media Resolutions
     Shareholder, and, subject to the express limitation set forth below, the
     taking by the Claims Representative of any and all actions and the making
     of any decisions required or permitted to be taken by the Claims
     Representative under Sections 6.02 and 6.03, including, without limitation,
     the exercise of the power to (i) agree to Edge's deductions against the
     Withheld Merger Consideration, or any portion thereof, in satisfaction of
     any Claims (for purposes of this Section 6.02(e), the term "Claims" is as
     defined in Sections 6.02 and 6.03), (ii) agree to, negotiate, enter into
     settlements and compromises of, and demand arbitration and comply with

     foregoing and all of the other terms, conditions and limitations of this
     Agreement. The Claims Representative will have unlimited authority and
     power to act on behalf of each Media Resolutions Shareholder with respect
     to Sections 6.02 and 6.03 and the disposition, settlement or other handling
     of all Claims, rights or obligations arising under this Agreement so long
     as all Media Resolutions Shareholders are treated in the same manner. The
     Media Resolutions Shareholders will be bound by all actions taken by the
     Claims Representative in connection with Sections 6.02 and 6.03, and Edge
     will be entitled to rely on any action or decision of the Claims
     Representative. In performing the functions specified in Sections 6.02 and
     6.03, the Claims Representative will not be liable to the Media Resolutions
     Shareholders in the absence of gross negligence or willful

     Representative subject to the right to resign as set forth below. The
     Claims Representative may resign from such position, effective upon a new
     representative being appointed in writing by Media Resolutions Shareholders
     who beneficially own a majority of the withheld portion of the Media
     Resolutions Common Stock. The Claims Representative will not be entitled to
     receive any compensation from Edge or the Media Resolutions Shareholders in
     connection with this Agreement. Each Media Resolutions Shareholder will pay
     to the Claims Representative his or her Pro Rata Portion of any
     out-of-pocket costs and expenses reasonably incurred by the Claims

     the resolution of such Claim, then such Media Resolutions Shareholder may
     retain separate counsel, and the fees and expenses of one such counsel for
     all applicable Media Resolutions Shareholders shall be borne by Edge rather
     than by any such Media Resolutions Shareholder) and will provide such Media
     Resolutions Shareholder with reasonable access to all relevant information
     and documents relating to the Claim and Edge's prosecution or defense
     thereof. If Edge does not make such election, then such Media Resolutions
     Shareholder shall be free to handle the prosecution or defense of any such
     Claim, will take all necessary steps to contest any such Claim involving
     third parties or to prosecute or defend such Claim to conclusion or
     settlement, will notify Edge of the progress of any such Claim, and will
     permit Edge, at the expense of Edge, to participate in such prosecution or
     defense and will provide Edge with reasonable access to all relevant
     information and documents relating to the Claim and such Media Resolutions
     Shareholder's prosecution or defense thereof. In either case, the party not
     in control of a Claim will fully cooperate with, and will cause its
     counsel, if any, to fully cooperate with, the other party in the conduct of
     the prosecution or defense of such Claim. Neither party will compromise or
     settle any such Claim without the written consent of either such Media
     Resolutions Shareholder (if Edge defends the Claim) or Edge (if such Media
     Resolutions Shareholder defends the Claim), such consent not to be
     unreasonably withheld. Notwithstanding the foregoing provisions of this
     Section 6.03(c), if two or more Media Resolutions Shareholders deliver,
     whether separately or together, a Claim to Edge arising from or relating to
     the same or a reasonably similar matter, then the Claims Representative
     shall act on behalf of each such Media Resolutions Shareholder bringing
     such a Claim for purposes of this Section 6.03.

          (d) Notice. Any written notice of a Claim required under this Section
              ------

              (i)  such Media Resolutions Shareholder's good faith estimate of
          the reasonably foreseeable maximum amount of the alleged Media

          by a third party plaintiff in an action brought against such Media
          Resolutions Shareholder); and

              (ii) A brief description in reasonable detail of the facts,
          circumstances or events giving rise to the alleged Media Resolutions

          including, without limitation, the identity and address of any

                                   ARTICLE VII
                                  MISCELLANEOUS

         7.01 Governing Law; Specific Performance; Dispute Resolution. The laws
              -------------------------------------------------------
of the State of Texas (without regard to its choice of law principles that might
apply the law of another jurisdiction) will govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties. Notwithstanding any other provision of
this Agreement, it is understood and agreed that the remedy of indemnity
payments and other remedies at law would be inadequate in the case of any breach
of the covenants contained herein and each party agrees that any other party
shall be entitled to equitable relief, including the remedy of specific
performance, without posting of bond or other security, with respect to any
breach or attempted breach of such covenants. Any dispute hereunder ("Dispute")
                                                                      -------
shall be settled by arbitration in Dallas, Texas and, except as herein
specifically stated, in accordance with the commercial arbitration rules of the
American Arbitration Association ("AAA Rules") then in effect. However, in all
                                   ---------
events, these arbitration provisions shall govern over any conflicting rules
that may now or hereafter be contained in the AAA Rules. Any judgment upon the
award rendered by the arbitrator may be entered in any court having jurisdiction
over the subject matter thereof. The arbitrator shall have the authority to
grant any equitable and legal remedies that would be available in any judicial
proceeding instituted to resolve a Dispute.

              (a) Compensation of Arbitrator. Any such arbitration will be
                  --------------------------
         conducted before a single arbitrator who will be compensated for his or
         her services at a rate to be determined by the parties or by the
         American Arbitration Association, but based upon a reasonable hourly or
         daily consulting rate for the arbitrator if the parties are not able to
         agree upon his or her rate of compensation.

              (b) Selection of Arbitrator. The American Arbitration Association
                  -----------------------
         will have the authority to select an arbitrator from a list of
         arbitrators who are lawyers familiar with Texas contract law and
         experienced in mergers and acquisitions; provided, however, that

AGREEMENT AND PLAN OF MERGER - Page 32

<PAGE>

         such lawyers cannot work for a firm then performing services for either
         party, that each party will have the opportunity to make such
         reasonable objection to any of the arbitrators listed as such party may
         wish and that the American Arbitration Association will select the
         arbitrator from the list of arbitrators as to whom neither party makes
         any such objection. If the foregoing procedure is not followed, each
         party will choose one person from the list of arbitrators provided by
         the American Arbitration Association (provided that such person does
         not have a conflict of interest), and the two persons so selected will
         select from the list provided by the American Arbitration Association
         the person who will act as the arbitrator.

              (c) Payment of Costs. Edge and the Media Resolutions Shareholders
                  ----------------
         will each pay 50% of the initial compensation to be paid to the
         arbitrator in any such arbitration and 50% of the costs of transcripts
         and other normal and regular expenses of the arbitration proceedings;
         provided, however, that the prevailing party in any arbitration will be
         entitled to an award of attorneys' fees and costs, and all costs of
         arbitration, including those provided for above, will be paid by the
         non-prevailing party, and the arbitrator will be authorized to make
         such determinations.

              (d) Burden of Proof. For any Dispute submitted to arbitration, the
                  ---------------
         burden of proof will be as it would be if the claim were litigated in a
         Texas judicial proceeding.

              (e) Award. Upon the conclusion of any arbitration proceedings
                  -----
         hereunder, the arbitrator will render findings of fact and conclusions
         of law and a written opinion setting forth the basis and reasons for
         any decision reached and will deliver such documents to each party to
         this Agreement along with a signed copy of the award.

              (f) Terms of Arbitration. The arbitrator chosen in accordance with
                  --------------------
         these provisions will not have the power to alter, amend or otherwise
         affect the terms of these arbitration provisions or the provisions of
         this Agreement.

              (g) Exclusive Remedy. Except as specifically otherwise provided in
                  ----------------
         this Agreement, arbitration will be the sole and exclusive remedy of
         the parties for any Dispute arising out of this Agreement.

         7.02 Assignment; Binding Upon Successors and Assigns. No party may
              -----------------------------------------------
assign any of its rights or obligations hereunder without the prior written
consent of the other party. This Agreement will be binding upon and inure to the
benefit of the parties and their respective successors and permitted assigns.

         7.03 Severability. If any provision of this Agreement, or the
              ------------
application thereof, is for any reason held to any extent to be invalid or
unenforceable, then the remainder of this Agreement and application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties. The parties further agree to replace such
unenforceable provision of this Agreement with valid and enforceable provisions
that will achieve, to the extent possible, the economic, business and other
purposes of the invalid or unenforceable provisions.

AGREEMENT AND PLAN OF MERGER - Page 33

<PAGE>

         7.04 Counterparts. This Agreement may be executed in counterparts, each
              ------------
of which will be an original as regards any party whose signature appears
thereon and all of which together will constitute one and the same instrument.
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of all parties reflected
hereon as signatories.

         7.05 Other Remedies. Except as otherwise provided herein, any and all
              --------------
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.

         7.06 Amendment and Waivers. Any term or provision of this Agreement may
              ---------------------
be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default of any succeeding
breach or default. This Agreement may be amended by the parties at any time.

         7.07 No Waiver. The failure of any party to enforce any of the
              ---------
provisions hereof will not be construed to be a waiver of the right of such
party thereafter to enforce such provisions. The waiver by any party of the
right to enforce any of the provisions hereof on any occasion will not be
construed to be a waiver of the right of such party to enforce such provisions
on any other occasion.

         7.08 Expenses. Other than sharing in equal portions the cost of the
              --------
Media Resolutions audit performed by Grant Thornton LLP, each party will bear
its respective expenses and fees of its own accountants, attorneys, investment
bankers and other professionals incurred with respect to this Agreement and the
transactions contemplated hereby; provided, however, that Media Resolutions will
not incur, in connection with the Merger and the related transactions
contemplated hereunder, expenses for fees and expenses of lawyers, accountants
and other professionals in excess of $15,000 for the period of time from the
Balance Sheet Date until the Closing Date, unless any such fees or expenses
incurred by Media Resolutions in excess of such $15,000 are paid by the Media
Resolutions Shareholder on or before the Closing Date.

         7.09 Notices. Any notice or other communication required or permitted
              -------

                    be deemed to be a part of the Indenture.

     INDENTURE, dated as of _________ __, 2002 between XTO ENERGY INC., a
Delaware corporation (hereinafter called the "Company"), and THE BANK OF NEW
YORK, a New York banking corporation, trustee (hereinafter called the
"Trustee").

                             RECITALS OF THE COMPANY

     The Company has duly authorized the execution and delivery of this
Indenture to provide for the issuance by the Company in one or more series from
time to time of debentures, notes or other evidences of indebtedness, unlimited
as to principal amount, to bear such rates of interest, to mature at such time
or times and to have such other provisions as shall be fixed as hereinafter
provided.

     This Indenture is subject to the provisions of the Trust Indenture of 1939,
as amended, that are required to be part of this Indenture and shall, to the
extent applicable, be governed by such provisions.

     All things necessary to make this Indenture a valid agreement of the
Company and the Trustee, in accordance with its terms, have been done.

                   NOW, THEREFORE, THIS INDENTURE WITNESSETH:

     For and in consideration of the premises and the purchase of the Securities
by the Holders thereof, it is mutually covenanted and agreed, for the equal and
proportionate benefit of all Holders of the Securities or of a series thereof,
as follows:

                                    ARTICLE I

             DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

Section 1.1  Definitions.

     "Act," when used with respect to any Holder, has the meaning specified in
Section 13.3.

     "Adjusted Consolidated Net Tangible Assets" means (without duplication), as
of the date of determination, (a) the sum of (i) discounted future net revenues
from proved oil and gas reserves of the Company and its Restricted Subsidiaries
(including, without limitation, oil and gas reserves owned by an oil and gas
royalty trust and attributable to the Company or a Restricted Subsidiary by
virtue of its ownership of Capital Stock of such royalty trust) calculated in
accordance with SEC guidelines before any state or federal income taxes, as
estimated by a nationally recognized firm of independent petroleum engineers in
a reserve report prepared as of the end of the Company's most recently
completed fiscal year, as increased by, as of the date of determination, the
estimated discounted future net revenues from (A) estimated proved oil and gas
reserves acquired since the date of such year-end reserve report, and (B)
estimated oil and gas reserves attributable to upward revisions of estimates of
proved oil and gas reserves since the date of such year-end reserve report due
to exploration, development or exploitation activities, in each case calculated
in accordance with SEC guidelines (utilizing the prices utilized in such

<PAGE>

year-end reserve report), and decreased by, as of the date of determination, the
estimated discounted future net revenues from (C) estimated proved oil and gas
reserves produced or disposed of since the date of such year-end reserve report
and (D) estimated oil and gas reserves attributable to downward revisions of
estimates of proved oil and gas reserves since the date of such year-end reserve
report due to changes in geological conditions or other factors which would, in
accordance with standard industry practice, cause such revisions, in each case
calculated in accordance with SEC guidelines (utilizing the prices utilized in
such year-end reserve report); provided that, in the case of each of the
determinations made pursuant to clauses (A) through (D), such increases and
decreases shall be as estimated by the Company's petroleum engineers, (ii) the
capitalized costs that are attributable to oil and gas properties of the Company
and its Restricted Subsidiaries to which no proved oil and gas reserves are
attributable, based on the Company's books and records as of a date no earlier
than the date of the Company's latest annual or quarterly financial statements,
(iii) the Net Working Capital on a date no earlier than the date of the
Company's latest annual or quarterly financial statements and (iv) the greater
of (A) the net book value on a date no earlier than the date of the Company's
latest annual or quarterly financial statements or (B) the appraised value, as
estimated by independent appraisers, of other tangible assets (including,
without duplication, investments in unconsolidated Restricted Subsidiaries) of
the Company and its Restricted Subsidiaries, as of the date no earlier than the
date of the Company's latest audited financial statements, minus (b) the sum of
(i) minority interests (other than a minority interest in a Subsidiary that is a
business trust or similar entity formed for the primary purpose of issuing
preferred securities the proceeds of which are loaned to the Company or a
Restricted Subsidiary), (ii) any net gas balancing liabilities of the Company
and its Restricted Subsidiaries reflected in the Company's latest audited
financial statements, (iii) to the extent included in (a)(i) above, the
discounted future net revenues, calculated in accordance with SEC guidelines
(using the prices utilized in the Company's year-end reserve report),
attributable to reserves which are required to be delivered to third parties to
fully satisfy the obligations of the Company and its Restricted Subsidiaries
with respect to Volumetric Production Payments on the schedules specified with
respect thereto and (iv) the discounted future net revenues, calculated in
accordance with SEC guidelines (using prices utilized in the Company's year-end
reserve report), attributable to reserves subject to Dollar-Denominated
Production Payments which, based on the estimates of production and price
assumptions included in determining the discounted future net revenues specified
in (a)(i) above, would be necessary to fully satisfy the payment obligations of
the Company and its Restricted Subsidiaries with respect to Dollar-Denominated
Production Payments on the schedules specified with respect thereto. If the
Company changes its method of accounting from the successful efforts method to
the full cost method or a similar method of accounting, "Adjusted Consolidated
Net Tangible Assets" will continue to be calculated as if the Company was still
using the successful efforts method of accounting.

     "Affiliate" means, with respect to any specified Person, any other Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with such specified Person. For the purposes of this definition,
"control," when used with respect to any Person, means the power to direct the
management and policies of such Person, directly or indirectly, whether through
the ownership of voting securities, by contract or otherwise; and the terms
"controlling" and "controlled" have meanings correlative to the foregoing. For
purposes of this definition, beneficial ownership of 10% or more of the voting
common equity (on a fully

                                       2

<PAGE>

diluted basis including options or warrants to purchase such equity, but only if
exercisable at the date of determination or within 60 days thereof) of a Person
shall be deemed to constitute control of such Person. No Person shall be deemed
an Affiliate of an oil and gas royalty trust solely by virtue of ownership of
units of beneficial interest in such trust.

     "Agent Members" has the meaning specified in Section 2.8(b).

     "Attributable Indebtedness" means, with respect to any particular lease
under which any Person is at the time liable and at any date as of which the
amount thereof is to be determined, the present value of the total net amount of
rent required to be paid by such Person under the lease during the primary term
thereof, without giving effect to any renewals at the option of the lessee,
discounted from the respective due dates thereof to such date of determination
at the rate of interest per annum implicit in the terms of the lease. As used in
the preceding sentence, the "net amount of rent" under any lease for any such
period shall mean the sum of rental and other payments required to be paid with
respect to such period by the lessee thereunder, excluding any amounts required
to be paid by such lessee on account of maintenance and repairs, insurance,
taxes, assessments, water rates or similar charges. In the case of any lease
which is terminable by the lessee upon payment of a penalty, such net amount of
rent shall also include the amount of such penalty, but no rent shall be
considered as required to be paid under such lease subsequent to the first date
upon which it may be so terminated.

     "Average Life" means, with respect to any Indebtedness, as at any date of

phraseology and form as may

                                       22

expense to them, shall provide for the exchange of all Securities of the series

Securities of such series shall be exchangeable for Definitive Securities of
such series upon surrender of the temporary Securities at the office or agency

charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
Definitive Securities of the same series of authorized denominations. Until so
exchanged, the temporary Securities of any series shall in all respects be

     (a)  Transfer and Exchange of Definitive Securities. When Definitive
Securities of any series are presented to the Securities Registrar with the
request:

          (i)   to register the transfer of such Definitive Securities, or

          (ii)  to exchange such Definitive Securities for an equal principal
amount of Definitive Securities of the same series of other authorized
denominations,

the Securities Registrar shall register the transfer or make the exchange as
requested if its requirements for such transactions are met; provided, however,
that the Definitive Securities presented or surrendered for registration of
transfer or exchange shall be duly endorsed or accompanied by a written
instrument of transfer in form satisfactory to the Securities Registrar duly
executed by the Holder thereof or by his attorney, duly authorized in writing.

     (b)  Restriction on Transfer of a Definitive Security for a Beneficial
Interest in a Global Security. A Definitive Security of a series may not be
exchanged for a beneficial interest in a Global Security of the same series
except upon satisfaction of the requirements set forth below. Upon receipt by
the Trustee of a Definitive Security of a series, duly endorsed or accompanied
by appropriate instruments of transfer, in form satisfactory to the Trustee,
together with written instructions directing the Trustee to make, or directing
the Security Custodian to make, an endorsement on the Global Security of the
same series to reflect an increase in the aggregate principal amount of the
Securities represented by such Global Security, then the Trustee shall cancel
such Definitive Security in accordance with Section 2.12 and cause, or direct
the Security Custodian to cause, in accordance with the standing instructions
and procedures existing between the Depositary and the Security Custodian, the
aggregate principal amount of Securities represented by such Global Security to
be increased accordingly. If no Global Securities of such series are then
outstanding, the Company shall issue and the Trustee shall authenticate a new
Global Security of the same series in the appropriate principal amount.

     (c)  Transfer and Exchange of Global Securities. The transfer and exchange
of Global Securities of any series or beneficial interests therein shall be
effected through the Depositary, in accordance with this Indenture and the
procedures of the Depositary therefor.

     (d)  Transfer of a Beneficial Interest in a Global Security for a
Definitive Security.

          (i)   Any Person having a beneficial interest in a Global Security of
any series may upon request to the Trustee exchange such beneficial interest for
a Definitive Security of the same series. Upon receipt by the Trustee of written
instructions, or such other form of instructions as is customary for the
Depositary, from the Depositary or its nominee on behalf of any Person having a
beneficial interest in a Global Security of a series. The Trustee or the
Security Custodian, at the direction of the Trustee, shall, in accordance with
the standing instructions and procedures existing between the Depositary and the
Security Custodian, cause the aggregate principal amount of Global Securities of

                                       24

<PAGE>

     such series to be reduced accordingly and, following such reduction, the
     Company shall execute and the Trustee shall authenticate and deliver to the
     transferee a Definitive Security of the same series in the appropriate
     principal amount.

          (ii)  Definitive Securities of a series issued in exchange for a
     beneficial interest in a Global Security of the same series pursuant to
     this Section 2.7(d) shall be registered in such names and in such
     authorized denominations as the Depositary, pursuant to instructions from
     its direct or indirect participants or otherwise, shall instruct the
     Trustee. The Trustee shall deliver such Definitive Securities to the
     Persons in whose names such Securities are so registered.

     (e)  Restrictions on Transfer and Exchange of Global Securities.
Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in subsection (f) of this Section 2.7), any Global Security
may not be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. Each Security
certificate evidencing Global Securities shall bear the paragraph referred to in
footnote 1 in the form of Security attached hereto as Exhibit A.

     (f)  Authentication of Definitive Securities in Absence of Depositary. If
at any time:

          (i)   the Depositary for Securities of a series notifies the Company
     that the Depositary is unwilling or unable to continue as Depositary for
     such Global Securities of such series and a successor Depositary for such
     Global Securities is not appointed by the Company within 90 days after
     delivery of such notice;

          (ii)  an Event of Default with respect to Securities of a series then
     Outstanding has occurred and is continuing and the Security Registrar has
     received a request from the Depositary to issue Definitive Securities of
     such series in lieu of all or a portion of the Global Security (in which
     case the Company shall deliver such Definitive Securities within 30 days of
     such request); or

          (iii) the Company, at its sole discretion, notifies the Trustee in
     writing that it elects to cause the issuance of Definitive Securities of a
     Series under this Indenture;

then the Company will execute, and the Trustee will authenticate and deliver,
Definitive Securities of such series in an aggregate principal amount equal to
the principal amount of the Global Securities of such series, in exchange for
such Global Securities and registered in such names as the Depositary shall
instruct the Trustee or the Company in writing.

     (g)  Cancellation and/or Adjustment of Global Security. At such time as all
beneficial interests in a Global Security of a series have either been exchanged
for Definitive Securities of such series, redeemed, repurchased or canceled,
such Global Security shall be returned to or retained and cancelled by the
Trustee. At any time prior to such cancellation, if any beneficial interest in
such Global Security is exchanged for Definitive Securities of such series,
redeemed,

                                       25

<PAGE>

repurchased or cancelled, the principal amount of Securities represented by such
Global Security shall be reduced and an endorsement shall be made on such Global
Security, by the Trustee or the Security Custodian, at the direction of the
Trustee to reflect such reduction.

     (h)   General Provisions with respect to Transfer and Exchanges.

           (i)   To permit registrations of transfers and exchanges, the Company

     shall execute and the Trustee shall authenticate Definitive Securities and
     Global Securities at the Registrar's request.

           (ii)  No service charge shall be made to a Holder for any
     registration of transfer or exchange or redemption of Securities (except as
     otherwise expressly permitted herein), but the Company or the Security
     Registrar may require payment of a sum sufficient to cover any transfer tax
     or similar governmental charge payable in connection therewith (other than
     such transfer tax or similar governmental charge payable upon exchanges
     pursuant to the last paragraph of Section 2.4 or Sections 2.5, 8.6 or
     10.7).

           (iii) The Trustee shall authenticate Definitive Securities and Global
     Securities in accordance with the provisions of Section 2.4.

           (iv)  Notwithstanding any other provisions of this Indenture to the
     contrary, the Company shall not be required to register the transfer or
     exchange of a Security between the record date and the next succeeding
     Interest Payment Date.

           (v)   Neither the Company nor the Trustee will have any
     responsibility or liability for any aspect of the records relating to, or
     payments made on account of, Securities of any series by the Depositary, or
     for maintaining, supervising or reviewing any records of the Depositary
     relating to such Securities. Neither the Company nor the Trustee shall be
     liable for any delay by the related Global Security Holder or the
     Depositary in identifying the beneficial owners of the related Securities,
     and the Company and the Trustee may conclusively rely on, and shall be
     protected in relying on, instructions from such Global Security Holder or
     the Depositary for all purposes (including with respect to the registration
     and delivery, and the respective principal amounts, of the Securities of
     any series to be issued).

           (vi)  Neither the Trustee, the Security Registrar nor the Company
     shall be required (A) to issue, register the transfer of or exchange any
     Security of a series during a period beginning at the opening of business
     15 days before the mailing of a notice of redemption of Securities of such
     series selected for redemption under Section 10.3 and ending at the close
     of business on the day of such mailing of the relevant notice of
     redemption, or (B) to register the transfer of or exchange any Security so
     selected for redemption in whole or in part, except the unredeemed portion
     of any Security being redeemed in part.

           (vii) All Securities issued upon any registration of transfer or
     exchange of Securities shall be the valid obligations of the Company
     evidencing the same debt, and

                                       26

<PAGE>

     entitled to the same benefits under this Indenture, as the Securities
     surrendered upon such registration of transfer or exchange.

           (viii)  Each Holder of a Security of a series agrees to indemnify the
     Company and the Trustee against any liability that may result from the
     transfer, exchange or assignment of such Holder's Security in violation of
     any provision of this Indenture and/or applicable federal or state
     securities law.

Section 2.8 Additional Provisions for Global Securities.

     (a) The Global Security of any series initially shall be registered in the
name of the Depositary for such Global Security or the nominee of such
Depositary and be delivered to the Trustee as custodian for such Depositary.

     (b)   Members of, or participants in, the Depositary ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary, or the Trustee as its custodian, or
under any Global Security, and the Depositary may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or shall impair, as between
the Depositary and its Agent Members, the operation of customary practices
governing the exercise of the rights of a holder of any Security.

     (c)   The registered holder of the Global Security of any series may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any permitted by a Holder
of Securities of such series.

Section 2.9 Mutilated, Destroyed, Lost and Stolen Securities.

     If (i) any mutilated Security is surrendered to the Trustee or (ii) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such
destroyed, lost or stolen Security, a new Security of the same series of like
tenor and principal amount bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

                                       27

<PAGE>

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 2.10 Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name such Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency of the Company maintained for such purpose pursuant to Section 9.2.

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date
by virtue of having been such Holder, and such and (to the extent lawful)
interest on such defaulted interest at the rate prescribed therefor in such
Security (such defaulted interest and interest thereon herein collectively
called "Defaulted Interest") may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

     (1)   The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited shall be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date, and in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
given in

                                       28

<PAGE>

the manner provided for in Section 14.5, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been so given, such Defaulted
Interest shall be paid to the Persons in whose names the Securities of such
series (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant
to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 2.11 Persons Deemed Owners.

     Prior to the due presentment of a Security for registration of transfer,
the Company, the Security Registrar, the Trustee and any agent of the Company or
the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of
(and premium, if any, on) and (subject to Section 2.10) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and none of the Company, the Security Registrar, the Trustee or any
agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12 Cancellation.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture. All cancelled Securities held by the Trustee shall be
delivered to the Company.

Section 2.13 Computation of Interest.

     Except as otherwise provided or contemplated by Section 2.1, interest on
the Securities of each series shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

                                       29

Section 2.14 CUSIP Numbers.

     The Company in issuing the Securities of any series may use "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

Section 2.15 Form of Trustee's Certificate of Authentication.

     The Trustee's certificate of authentication shall be in substantially the
following form:

     This is one of the Securities of the series designated herein and referred
to in the within-mentioned Indenture.

payment of all amounts due the Trustee under Section 5.6, the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging

      delivered to the Trustee for cancellation, or

             (ii)   all Securities of that series not theretofore delivered to
      the Trustee for cancellation

                    (A)  have become due and payable, or

                    (B)  will become due and payable at their Stated Maturity

      become due and payable) or to the Stated Maturity or Redemption Date, as

respect to any series of Securities, the obligations of the Company to the
Trustee under Section 5.6 shall survive and, if money shall have been deposited

Indebtedness, property or assets of the Company or any Restricted Subsidiary
having a Fair Market Value in excess of $10,000,000 individually or in the
aggregate; provided that if any such proceedings or actions are terminated or
rescinded, or such Indebtedness is repaid, such Event of Default under this
Indenture and any consequential acceleration of Securities shall be
automatically rescinded, so long as (i) such rescission does not conflict with
any judgment or decree and (ii) the holder of such Indebtedness shall not have
applied any such property or assets in satisfaction of such Indebtedness; or

PBGC Plan, Multiple Employer Plan or Multiemployer Plan which in combination
with one or more of any events described in (i) through (vi) above (determined
without regard to whether the event or condition taken alone would or could
result in a material liability) that has occurred or exists, would likely
subject the Company or any Restricted Subsidiary to any material tax, penalty or
other liability (for purposes of this paragraph (g) the term "material" and
"material liability" shall mean any tax, penalty or liability in excess of
$10,000,000); or

Section 4.2  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in
Section 4.1(i) or (j)) with respect to Securities of any series at the time
Outstanding shall occur and be continuing, the Trustee, by written notice to the

Securities as may be specified in the terms thereof), premium, if any, and
accrued interest on all Securities of that series to be due and payable
immediately, upon which declaration all amounts payable in respect of such

     At any time after a declaration of acceleration with respect to Securities
of any series has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind such declaration and its consequences if:

     (a)  the Company has paid or deposited with the Trustee a sum sufficient to
pay:

          (i)    all sums paid or advanced by the Trustee under this Indenture
     and the reasonable compensation, expenses, disbursements and advances of
     the Trustee, its agents and counsel,

          (ii)   all overdue interest on all Outstanding Securities of that
     series,

          (iii)  all unpaid principal of (and premium, if any, on) any
     Outstanding Securities of that series which has become due otherwise than
     by such declaration of acceleration and interest on such unpaid principal
     at the rate borne by such Securities, and

          (iv)   to the extent that payment of such interest is lawful, interest
     upon overdue interest and overdue principal which has become due otherwise
     than by such declaration of acceleration (without duplication of any amount
     deposited pursuant to clauses (ii) and (iii) above), at the rate or rates
     prescribed therefor in such Securities of that series;

     (b)  the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction; and

     (c)  all Events of Default with respect to Securities of that series, other
than the nonpayment of principal of (or premium, if any, on), and interest on
Securities of that series that has become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 4.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     Notwithstanding the foregoing, in the event of a declaration of
acceleration in respect of Securities of a series because of an Event of Default
specified in (A) Section 4.1(e) shall have occurred and be continuing, such
declaration of acceleration and any consequential acceleration shall be
automatically rescinded if the Indebtedness that is the subject of such Event of
Default has been repaid, or if the default relating to such Indebtedness is
waived or cured and if such Indebtedness has been accelerated, then the holders
thereof have rescinded their declaration of acceleration in respect of such
Indebtedness (provided, in each case, that such repayment, waiver, cure or
rescission is effected within a period of 10 days from the continuation of such
default beyond the applicable grace period or the occurrence of such
acceleration), or (B) Section 4.1(f) shall have occurred and be continuing, such
declaration and any consequential acceleration shall be automatically rescinded
if the proceedings or enforcement action with respect to the Indebtedness that
is the subject of such Event of Default are terminated or rescinded, or such

                                       35

<PAGE>

Indebtedness has been repaid and only so long as the holder of such Indebtedness
shall not have applied any Property referenced in such Section 4.1(f) in
satisfaction of such Indebtedness; and, in the case of both (A) and (B) above,
written notice of such repayment, or cure or waiver and rescission, as the case
may be, shall have been given to the Trustee by the Company and countersigned by
the holders of such Indebtedness or a trustee, fiduciary or agent for such
holders or other evidence satisfactory to the Trustee of such events is provided
to the Trustee, within 30 days after such declaration of acceleration in respect
of such Securities, and no other Event of Default has occurred during such
30-day period which has not been cured or waived during such period, and so long
as such recision of the declaration of acceleration of such Securities does not
conflict with any judgement or decree as certified to the Trustee by the
Company.

Section 4.3  Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

             (i)   default is made in the payment of any installment of interest
     on any Security when such interest becomes due and payable and such default
     continues for a period of 30 days, or

             (ii)  default is made in the payment of the principal of (or
     premium, if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee for the benefit
of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installment of interest,
at the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the Property of the Company or any other obligor upon such Securities, wherever
situated.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in any provision of such Securities or this Indenture or
in aid of the exercise of any power granted therein or herein, or to enforce any
other proper remedy.

Section 4.4  Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the Property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
of any series shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand on the Company or such other obligor for the payment of overdue
principal, premium, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise:

             (i)   to file and prove a claim for the whole amount of principal
     (and premium, if any) and interest owing and unpaid in respect of such
     Securities and to file such other papers or documents and take any other
     actions including participation as a full member of any creditor or other
     committee as may be necessary or advisable in order to have the claims of
     the Trustee (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

             (ii)  to collect and receive any moneys or other Property payable
     or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 5.6.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

Section 4.5  Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

             (i)   such Holder has previously given written notice to the
     Trustee of a continuing Event of Default with respect to the Securities of
     that series;

             (ii)  the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

             (iii) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

             (iv)  the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity has failed to institute any such proceeding;
     and

             (v)   no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of Outstanding Securities of that series;

it being understood and intended that no one or more Holders of Securities of a
series shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders of Securities of that series, or to obtain or to seek to
obtain priority or preference over any other Holders of Securities of that

                                       38

such Security of the principal of (and premium, if any, on) and (subject to
Section 2.10) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and, if applicable to such Security, to convert or exchange such Security
in accordance with provisions of such Security, and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

Section 4.9  Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereunder,
and all rights and remedies of the Trustee and the Holders shall continue as

Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 4.11 Delay or Omission Not Waiver.

or remedy accruing upon any Event of Default shall impair any such right or

or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

power conferred on the Trustee, provided that:

             (i)   such direction shall not be in conflict with any rule of law
     or with this Indenture,

             (ii)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction, and

             (iii) the Trustee need not take any action which might involve it

for every purpose under this Indenture, but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon.

notice of such Default known to the Trustee, unless such Default shall have been
cured or waived; provided, however, that, except in the case of a Default in the
payment of the principal of (or premium, if any, on) or interest on any
Security, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determines

provided, further, that in the case of any Default of the character specified in

     The Company agrees:

     (a)     to pay to the Trustee from time to time such compensation as shall

by any provision of law in regard to the compensation of a trustee of an express
trust);

     (b)     except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances

<PAGE>

harmless the Trustee shall constitute additional indebtedness hereunder and
shall survive the satisfaction and discharge of this Indenture or any other

of an Event of Default specified in paragraph (i) or (j) of Section 4.1 of this

condition at least annually, pursuant to law or to the requirements of federal,
state, territorial or District of Columbia supervising or examining authority,
then for the purposes of this Section 5.7, the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this

Indenture Act.

Section 5.9  Resignation and Removal; Appointment of Successor.

     (a)     No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 5.10.

     (b)     The Trustee may resign at any time with respect to Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 5.10 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor

delivered to the Trustee and to the Company. If the instrument of acceptance by
a successor Trustee required by Section 5.10 shall not have been delivered to
the Trustee within 30 days after the giving of such notice of removal, the
Trustee being removed may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

     (d)  If at any time:

          (i)   the Trustee shall fail to comply with the provisions of TIA
     Section 310(b) after written request therefor by the Company or by any

     months, or

          (ii)  the Trustee shall cease to be eligible under Section 5.7 and
     shall fail to resign after written request therefor by the Company or by
     any Holder who has been a bona fide Holder of a Security for at least six
     months, or

          (iii) the Trustee shall become incapable of acting or shall be
     adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation;

then, in any such case, (A) the Company, by a Board Resolution, may remove the
Trustee, or (B) subject to TIA Section 315(e), any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for

or incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance

of such series and supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to Securities of a series shall have been so
appointed by the Company or Holders and accepted appointment in the manner
required by Section 5.10, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series. Such successorship may, but need not be, evidenced by a supplemental
indenture.

     (f)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to the Holders of
Securities of each series so affected in the manner provided for in
Section 13.5. Each notice shall include the name of the successor Trustee and
the address of its Corporate Trust Office.

Section 5.10 Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective, and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of all amounts due it under
Section 5.6, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments to more fully and

business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities;
and in case at that time any of the Securities shall not have been
authenticated, any successor Trustee may authenticate such Securities either in
the name of any predecessor hereunder or in the name of the successor Trustee;
and in all such cases such certificates shall have the full force that is
provided anywhere in the Securities or in this Indenture; provided, however,
that the right to adopt the certificate of authentication of any predecessor
Trustee or to authenticate Securities in the name of any predecessor Trustee
shall apply only to its successor or successors by merger, conversion or
consolidation.

Section 5.12 Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor under the Securities), the Trustee shall be subject to the

that series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so

written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any,
on) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general

Indenture, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect the corporate existence, rights
(charter and statutory) and franchises of the Company and each Restricted
Subsidiary; provided, however, that the Company shall not be required to
preserve any such existence of its Restricted Subsidiaries, right or franchise,
if the Board of Directors shall determine that the preservation thereof is no

Restricted Subsidiaries, taken as a whole, and that the loss thereof is not
disadvantageous in any material respect to Holders of Securities of any series.

Section 9.5 Payment of Taxes and Other Claims.

     The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Restricted
Subsidiary or upon the income, profits or Property of the Company or any
Restricted Subsidiary and (b) all lawful claims for labor, materials and
supplies, which, if unpaid, might by law become a Lien upon the Property of the
Company or any Restricted Subsidiary; provided, however, that the Company shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings and for which
appropriate provision has been made in accordance with GAAP.

the judgment of the Company may be necessary so that its business may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
maintenance of any of such Properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business or the business of any
Restricted Subsidiary and not disadvantageous in any material respect to the
Holders of Securities of any series. Notwithstanding the foregoing, nothing
contained in this Section 9.6 shall limit or impair in any way the right of the
Company and its Restricted Subsidiaries to sell, divest and otherwise to engage
in transactions that are otherwise permitted by this Indenture.

Section 9.7 Insurance.

     The Company shall at all times keep all of its and its Restricted
Subsidiaries' Properties which are of an insurable nature insured (including
appropriate self-insurance) with insurers,

believed by the Company to be responsible, against loss or damage to the extent
that, in the reasonable good faith opinion of the Company, property of similar
character is usually so insured by corporations similarly situated and owning
like properties.

     The Company may adopt such other plan or method of protection, in lieu of
or supplemental to insurance with insurers, whether by the establishment of an
insurance fund or reserve to be held and applied to make good losses from
casualties, or otherwise, conforming to the systems of self-insurance, in the
reasonable good faith opinion of the Company, maintained by corporations
similarly situated and owning like properties, as may be determined by the Board
of Directors.

Section 9.8 Statement by Officers as to Default.

     (a) The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year of the Company and within 45 days of the end of each of the
first, second and third quarters of each fiscal year of the Company, an
Officers' Certificate, one of the signers of which shall be the principal
executive officer, principal financial officer or principal accounting officer
of the Company, stating that a review of the activities of the Company and its
Subsidiaries during the preceding fiscal quarter or fiscal year, as applicable,
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of such Officer's knowledge the
Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which such Officer may have knowledge and what action the
Company is taking or proposes to take with respect thereto). Such Officers'
Certificate shall comply with TIA Section 314(a)(4). For purposes of this
Section 9.8(a), such compliance shall be determined without regard to any period
of grace or requirement of notice under this Indenture.

     (b) The Company shall, so long as any Securities of any series are
Outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of
any Default or Event of Default or default in the performance of any covenant,
agreement or condition contained in this Indenture, an Officers' Certificate
specifying such Default or Event of Default and what action the Company proposes
to take with respect thereto within 10 days of its occurrence.

Section 9.9 Reports.

     The Company shall file with the Trustee and the Commission, and transmit to
Holders, such information, documents and reports as required under the Trust
Indenture Act. In connection therewith, the Company shall file with the Trustee
copies of all annual, quarterly and other reports and other information and
documents that the Company is required to file with the Commission under the
Exchange Act. Each such report or other information or document shall be filed
with the Trustee within 15 days after the filing thereof with the Commission. If
the Company at any time is no longer subject to the reporting requirements of
Section 13 or 15(d) of

                                       55

<PAGE>

the Exchange Act, the Company will file with the Trustee annual and quarterly
reports and other documents that the Company would be required to file with the
Commission if it were subject to Section 13 of the Exchange Act, and the Company
shall file such reports and other documents with the Trustee within 15 days
after the date on which the Company would be required to file them with the
Commission if the Company were so required.

         Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

Section 9.10  Limitation on Liens.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create, incur, assume, affirm or suffer to exist or
become effective any Lien of any kind, except for Permitted Liens, on or with
respect to any of its property or assets (including any intercompany notes),
whether owned at the date of this Indenture or thereafter acquired, or any
income, profits or proceeds therefrom, unless (a) in the case of any Lien
securing Subordinated Indebtedness, the Securities (then Outstanding and
thereafter created) are secured by a Lien on such property, assets or proceeds
that is senior in priority to such Lien and (b) in the case of any other Lien,
the Securities (then Outstanding and thereafter created) are directly secured
equally and ratably with the obligation or liability secured by such Lien.

Section 9.11  Waiver of Certain Covenants.

         The Company may, with respect to the Securities of any series, omit in
any particular instance to comply with any term, provision or condition set
forth in Sections 9.5 through 9.10 if, before or after the time for such
compliance, the Holders of at least a majority in principal amount of the
Outstanding Securities of each series affected, by Act of such Holders, waive
such compliance in such instance with such term, provision or condition, but no
such waiver shall extend to or affect such term, provision or condition except
to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

Section 10.2  Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. In case of any redemption at the election of the Company,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and, if less than all the Securities of a
series are to be redeemed, the principal amount of Securities of the series to
be redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 10.3. Any election to redeem Securities shall be revocable until the
Company gives a notice of redemption pursuant to Section 10.4 to the Holders of
Securities to be redeemed.

Section 10.3  Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not less than 30 days nor
more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series not previously called for redemption, pro
rata, by lot or by any other method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
of the principal of Securities of such series; provided, however, that any such
partial redemption shall be in integral multiples of $1,000.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities shall relate, in
the case of any Security redeemed or to be redeemed only in part, to the portion
of the principal amount of such Security which has been or is to be redeemed.

Section 10.4 Notice of Redemption.

         Notice of redemption shall be given in the manner provided for in
Section 13.5 not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed.

         All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number) and shall state:

         (a)  the Redemption Date;

         (b)  the Redemption Price;

                                       57

<PAGE>

         (c) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of a partial redemption of any
series, the principal amounts) of the particular Securities to be redeemed;

         (d) that on the Redemption Date the Redemption Price (together with
accrued interest to the Redemption Date payable as provided in Section 10.6)
will become due and payable upon each such Security, or the portion thereof, to
be redeemed, and that, unless the Company shall default in the payment of the
Redemption Price and any applicable accrued interest, interest thereon will
cease to accrue on and after said date;

         (e) if applicable, that the redemption is for a sinking fund; and

         (f) the place or places where such Securities are to be surrendered for
payment of the Redemption Price.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company. Notice, if given in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. In any case, failure to give
such notice or any defect therein to the Holder of any Security of a series
shall not affect the validity of any proceedings for the redemption of other
Security of such series.

Section 10.5  Deposit of Redemption Price.

         On or before 11:00 A.M., New York City time, on any Redemption Date,
the Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 9.3) an amount of money sufficient to pay the Redemption
Price of, and accrued and unpaid interest on, all the Securities which are to be
redeemed on such Redemption Date.

Section 10.6  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued and unpaid interest to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued and unpaid interest)
such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with accrued and unpaid
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 2.10.

                                       58

<PAGE>

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Security.

Section 10.7  Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at the office or agency of the Company maintained for such purpose pursuant to
Section 9.2 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of the same series and of like tenor, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal
amount of the Security so surrendered.

Section 10.8  Sinking Fund.

         The terms of the Securities of any series may provide for a sinking
fund for the retirement of Securities of that series. The following provisions
shall apply to any such sinking fund except as otherwise specified for the
Securities of such series.

         (a) The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment."

         (b) In lieu of making all or any part of any mandatory sinking fund
payment in cash with respect to any Securities of a series, the Company may at
its option satisfy all or part of its sinking fund payment obligation with
respect to such Securities by (i) delivery of Outstanding Securities of that
series theretofore purchased or otherwise acquired by the Company (other than
any Securities previously called for redemption) or (ii) applying as a credit
the principal amount of Securities of that series which have been redeemed
either at the election of the Company pursuant to the terms of such Securities
or through the application of permitted optional sinking fund payments pursuant
to the terms of such Securities; provided that such Securities have not been
previously so credited. Such Securities shall be received and credited for such
purpose by the Trustee at the redemption price specified in such Securities for
redemption through operation of the sinking fund, and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

         (c) Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 10.8(b) (including therewith delivery to the Trustee of any
Securities to be so

                                       59

<PAGE>

delivered), and whether the Company intends to make any permitted optional
sinking fund payment with respect to such series. Not less than 45 days prior to
such sinking fund payment date, the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
10.3, and the Company shall cause notice of the redemption thereof to be given
at its expense in the manner provided in Section 10.4 except that the notice of
redemption shall also state that the Securities are being redeemed by operation
of the sinking fund. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
10.6 and 10.7.

                                   ARTICLE XI

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 11.1  Company's Option to Effect Defeasance or Covenant Defeasance.

         Unless pursuant to Section 2.1 provision is made that this Article
shall not be applicable to the Securities of any series, the Company may, at its
option by Board Resolution, at any time, with respect to the Outstanding
Securities of any series designated in accordance with Section 2.1 as being
defeasible pursuant to this Article XI, elect to have either Section 11.2 or
Section 11.3 be applied to all Outstanding Securities of such series upon
compliance with the conditions set forth below in this Article XI.

Section 11.2  Defeasance and Discharge.

         Upon the Company's exercise under Section 11.1 of the option applicable
to this Section 11.2, the Company shall be deemed to have been discharged from
its obligations with respect to all Outstanding Securities of the applicable
series on the date the conditions set forth in Section 11.4 are satisfied
(hereinafter referred to as "legal defeasance"). For this purpose, such legal
defeasance means that the Company shall be deemed (a) to have paid and
discharged their respective obligations under the Outstanding Securities of such
series; provided, however that the Securities shall continue to be deemed to be
"Outstanding" for purposes of Section 11.5 and the other Sections of this
Indenture referred to in clauses (i) and (ii) below, and (b) to have satisfied
all their other obligations under such Securities and this Indenture insofar as
such Securities are concerned (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of Outstanding Securities of such series to
receive, solely from the trust fund described in Section 11.4 and as more fully
set forth in such Section, payments in respect of the principal of (and premium,
if any, on) and interest on such Securities when such payments are due (or at
such time as the Securities would be subject to redemption at the option of the
Company in accordance with this Indenture), (ii) the respective obligations of
the Company under Sections 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 4.8, 4.14, 5.6, 5.9,
5.10, 9.1, 9.2 and 9.3, (iii) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (iv) the obligations of the Company under this
Article XI. Subject to compliance with this Article XI, the Company may exercise
its option under Section 11.1 applicable to this Section

                                       60

<PAGE>

11.2 notwithstanding the prior exercise of its option under Section 11.1
applicable to Section 11.3.

Section 11.3  Covenant Defeasance.

         Upon the Company's exercise under Section 11.1 of the option applicable
to this Section 11.3, the Company shall be released from its obligations under
any covenant contained in Article VII and in Sections 9.5 through 9.10 (and any
other covenant, as may be determined pursuant to Section 2.1, of the applicable
series of Securities subject to this provision) with respect to the Outstanding
Securities of the applicable series on and after the date the conditions set
forth below are satisfied (hereinafter referred to as "covenant defeasance"),
and the Securities of such series shall thereafter be deemed not to be
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to the Outstanding Securities, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Sections 4.1(c) or 4.1(d) or any additional Event of Default included in the
Securities of such series, but, except as specified above, the remainder of this
Indenture and such Securities shall be unaffected thereby.

Section 11.4  Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to application of either Section
11.2 or Section 11.3 to the Outstanding Securities of any series:

         (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 5.7 who shall agree to comply with the provisions of this Article XI
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities of such series, (i) cash in
U.S. Dollars in an amount, or (ii) U.S. Government Obligations which through the
scheduled payment of principal and interest in respect thereof in accordance
with their terms will provide, not later than one day before the due date of any
payment, money in an amount, or (iii) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, the principal of (and premium, if any, on) and
interest on the Outstanding Securities of such series on the Stated Maturity (or
Redemption Date, if applicable) of such principal (and premium, if any) or
installment of interest; provided that the Trustee shall have been irrevocably
instructed in writing by the Company to apply such money or the proceeds of such
U.S. Government Obligations to said payments with respect to the Securities of
such series. Before such a deposit, the Company may give to the Trustee, in
accordance with Section 10.2, a notice of its election to redeem all of the
Outstanding Securities of such series at a future date in accordance with
Article X, which notice

                                       61

<PAGE>

shall be irrevocable. Such irrevocable redemption notice, if given, shall be
given effect in applying the foregoing. For this purpose, "U.S. Government
Obligations" means securities that are (x) direct obligations of the United
States of America for the timely payment of which its full faith and credit is
pledged or (y) obligations of a Person controlled or supervised by and acting as
an agency or instrumentality of the United States of America the timely payment
of which is unconditionally guaranteed as a full faith and credit obligation by
the United States of America, which, in either case, are not callable or
redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act), as custodian with respect to any such U.S. Government
Obligation or a specific payment of principal of or interest on any such U.S.
Government Obligation held by such custodian for the account of the holder of
such depository receipt, provided that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to the
holder of such depository receipt from any amount received by the custodian in
respect of the U.S. Government Obligation or the specific payment of principal
of or interest on the U.S. Government Obligation evidenced by such depository
receipt.

         (b) No Default or Event of Default with respect to the Securities of
such series shall have occurred and be continuing on the date of such deposit.

         (c) Such legal defeasance or covenant defeasance shall not cause the
Trustee to have a conflicting interest under this Indenture or the Trust
Indenture Act with respect to any securities of the Company.

         (d) Such legal defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under any other material
agreement or instrument to which the Company is a party or by which it is bound,
as evidenced to the Trustee in an Officers' Certificate delivered to the Trustee
concurrently with such deposit.

         (e) In the case of an election under Section 11.2, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling, or (ii) since the date of this Indenture there has been a change in
the applicable Federal income tax laws; in either case providing that the
Holders of the Outstanding Securities of such series will not recognize income,
gain or loss for federal income tax purposes as a result of such legal
defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such legal
defeasance had not occurred (it being understood that (x) such Opinion of
Counsel shall also state that such ruling or applicable law is consistent with
the conclusions reached in such Opinion of Counsel and (y) the Trustee shall be
under no obligation to investigate the basis of correctness of such ruling).

         (f) In the case of an election under Section 11.3, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the Outstanding Securities will not recognize income, gain or loss
for federal income tax purposes as a result of such covenant defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such covenant defeasance had not
occurred.

                                       62

<PAGE>

         (g) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that the Securities of such series, if then listed on
any securities exchange, will not be delisted as a result of such legal
defeasance or covenant defeasance.

         (h) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the legal defeasance under Section
11.2 or the covenant defeasance under Section 11.3 (as the case may be) have
been complied with.

Section 11.5  Deposited Money and U.S. Government Obligations to Be Held in
              Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 9.3, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 11.5, the "Trustee") pursuant to Section 11.4 in respect of the
Outstanding Securities of any series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 11.4 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article XI to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 11.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent legal defeasance or covenant
defeasance, as applicable, in accordance with this Article.

Section 11.6  Reinstatement.

         If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 11.5 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities of the applicable series shall be revived and reinstated as though no
deposit had occurred pursuant to Section 11.2 or 11.3, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 11.5; provided, however, that if the Company makes any
payment of principal of (or premium, if any, on) or interest on any Security of
a series following the reinstatement of its

                                       63

<PAGE>

obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money held by the Trustee or
Paying Agent.

                                   ARTICLE XII

                                   CONVERSION

Section 12.1  Applicability; Conversion Privilege and Conversion Price.

         If Securities of any series are designated pursuant to Section 2.2 as
convertible into Common Stock of the Company, such conversion shall be in
accordance with the terms of this Article, unless otherwise specified in the
terms of such Securities. Conversion provisions for Securities of any series
denominated in a foreign currency or for conversion into a security other than
Common Stock of the Company shall be specified in the terms of such Securities
in accordance with Section 2.2. Reference in this Article to "Common Stock"
shall mean the common stock, par value $0.01 per share, of the Company
authorized on the date of this Indenture and any other class of stock resulting
from successive changes or reclassifications of such common stock.

         Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Security of a series to which this Article
applies, or any portion of the principal amount thereof which equals $1,000 or
an integral multiple thereof, may be converted at the principal amount thereof,
or of such portion thereof, into fully paid and non-assessable shares
(calculated as to each conversion to the nearest 1/100th of a share) of Common
Stock, at the conversion price in effect at the time of conversion. Such
conversion right shall expire at the close of business on the date specified for
Securities of such series. In case a Security or portion thereof is called for
redemption, such conversion right in respect of the Security or portion so
called shall expire at the close of business on the Business Day immediately
preceding the Redemption Date, unless the Company defaults in making the payment
due upon redemption.

         The price at which shares of Common Stock shall be delivered upon
conversion (the "conversion price") shall be the price specified for the
Securities of such series, subject to adjustment as provided in this Article.

Section 12.2  Conversion Procedure.

     In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender to the Company such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company
maintained pursuant to Section 9.2, accompanied by written notice of conversion
in substantially the form set forth in the Security (except in the case of a
depositary of a Global Security, for which the customary procedures of the
depositary will apply). Securities surrendered for conversion during the period
from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
shall (except in the case of Securities or portions thereof which have been
called for redemption on a Redemption Date within such period) be accompanied by

                                       64

<PAGE>

payment in New York Clearing House funds or other funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of Securities being surrendered for conversion. Except
as provided in the immediately preceding sentence, no payment or adjustment
shall be made upon any conversion on account of any interest accrued on the
Securities surrendered for conversion or on account of any dividends on the
Common Stock issued upon conversion.

         Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at and
after such time. As promptly as practicable on or after the conversion date, the
Company shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with any payment in lieu of any fraction of a share, as
provided in Section 12.3.

         In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of the applicable series of authorized denominations in aggregate
principal amount equal to the unconverted portion of the principal amount of
such Security.

Section 12.3  Fractions of Shares.

         No fractional shares of Common Stock or scrip representing fractions of
shares shall be issued upon conversion of Securities. If more than one Security
of a series shall be surrendered for conversion at one time by the same Holder,
the number of full shares which shall be issuable upon conversion thereof shall
be computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof) of that series so surrendered. Instead of any
fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay to the Holder of such Security an amount in cash (computed to
the nearest cent) based upon the closing price of the Common Stock on the
Business Day immediately preceding the date of conversion.

Section 12.4  Adjustment of Conversion Price.

         The conversion price shall be subject to adjustment from time to time
as follows:

         (a) In case the Company shall pay or make a dividend or other
distribution on any class of its capital stock in shares of its Common Stock,
then the conversion price in effect at the opening of business on the day
following the record date for determination of stockholders entitled to receive
such dividend or other distribution shall be reduced by multiplying such
conversion price by a fraction of which the numerator shall be the number of
shares of Common Stock issued and outstanding at the close of business on such
record date and the denominator shall be the sum of such number of shares and
the total number of shares constituting such

                                       65

<PAGE>

dividend or other distribution. Such reduction shall become effective
immediately after the opening of business on the day following such record date.

     (b) In case the Company shall issue rights, options or warrants to all
holders of its outstanding shares of Common Stock entitling them to subscribe
for or purchase shares of Common Stock at a price per share less than the
current market price per share of the Common Stock on the record date for
determination of stockholders entitled to receive such rights, options or
warrants, then the conversion price in effect at the opening of business on the
day following such record date shall be reduced by multiplying such conversion
price by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on such record date plus the
number of shares of Common Stock which the aggregate of the offering price of
the total number of shares of Common Stock so offered for subscription or
purchase would purchase at such current market price and the denominator shall
be the number of shares of Common Stock outstanding at the close of business on
such record date plus the number of shares of Common Stock so offered for
subscription or purchase. Such reduction shall become effective immediately
after the opening of business on the day following such record date.
Notwithstanding the foregoing, in case the Company shall issue rights, options
or warrants ("Stockholder Rights") to all holders of its Common Stock entitling
the holders thereof to subscribe for or purchase shares of Common Stock, which
rights or warrants (i) are deemed to be transferred with such shares of Common
Stock, (ii) are not exercisable and (iii) are also issued in respect of future
issuances of Common Stock, in each case until the occurrence of a specified
event or events, such Stockholder Rights shall for purposes of this Section 12.4
not be deemed issued or distributed until the occurrence of the earliest of such
specified events and the conversion price shall not be reduced until the
occurrence of such earliest specified event. If the conversion price is reduced
pursuant to this paragraph (b) as a result of any rights, warrants or options
that are issued by the Company and if at the end of the period during which such
warrants, options, or rights are exercisable, not all such warrants, options or
rights shall have been exercised, the conversion price shall be immediately
readjusted to what it would have been had the above fraction been computed based
on the number of shares of Common Stock actually issued in respect of such
warrants, options or rights, as the case may be.

     (c) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, then the conversion price in effect at
the opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately reduced by multiplying such
conversion price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the day upon
which such subdivision becomes effective before giving effect to such
subdivision and the denominator shall be the number of shares of Common Stock
outstanding at the close of business on the day such subdivision becomes
effective after giving effect to such subdivision. Conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, then the conversion price in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately increased by multiplying such conversion
price by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the day upon which such
combination becomes effective before giving effect to such combination and the
denominator shall be the number of shares of Common Stock outstanding at

                                       66

<PAGE>

the close of business on the day such combination becomes effective after giving
effect to such combination. Such reduction or increase, as the case may be,
shall become effective immediately after the opening of business on the day
following the day upon which such subdivision or combination becomes effective.

     (d) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock evidences of its indebtedness or assets (including
securities, but excluding (i) an issuance, dividend or distribution referred to
in paragraphs (a) and (b) of this Section paid exclusively in cash or upon the
dissolution, liquidation or winding up of the Company or (ii) Stockholder
Rights), then the conversion price shall be adjusted so that the same shall
equal the price determined by multiplying the conversion price in effect
immediately prior to the close of business on the record date for determination
of stockholders entitled to receive such distribution by a fraction of which the
numerator shall be the current market price per share of the Common Stock on
such record date minus the then fair market value (as determined by the Board of
Directors of the Company, whose determination shall be conclusive and described
in a Board Resolution) of the portion of the evidences of indebtedness or assets
so distributed applicable to one share of Common Stock and the denominator shall
be such current market price per share of the Common Stock on such record date.
Such adjustment shall become effective immediately prior to the opening of
business on the day following such record date.

     (e) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any cash that is distributed as part
of a distribution referred to in paragraph (d) of this Section) in an aggregate
amount that, together with (i) the aggregate amount of any other distributions
to all holders of its Common Stock made exclusively in cash within the l2 months
preceding the date of payment of such distribution and in respect of which no
conversion price adjustment pursuant to paragraph (e) of this Section has been
made and (ii) the aggregate of any cash exceeds 10% of the product of the
current market price per share of the Common Stock on the date fixed for the
determination of stockholders entitled to receive such distribution multiplied
by the number of shares of Common Stock outstanding on such date, then the
conversion price shall be reduced so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction contemplated by this
paragraph (e) by a fraction of which the numerator shall be the current market
price per share of the Common Stock on such date minus the amount of cash so
distributed applicable to one share of Common Stock and the denominator shall be
such current market price per share of the Common Stock. Such reduction shall
become effective immediately prior to the opening of business on the date
following the date fixed for the payment of such distribution.

     (f) The reclassification of Common Stock into securities other than Common
Stock (excluding any reclassification upon a merger or consolidation to which
Section 12.12 applies) shall be deemed to involve a distribution of such
securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the record date
for determination of stockholders entitled to receive such distribution" within
the meaning of paragraph (d) of this Section). If such reclassification changes
the number of outstanding shares of Common Stock, then such reclassification
shall be deemed (in addition to any effect provided in the previous sentence) a
subdivision or combination, as the case may be,

                                       67

<PAGE>

of the number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall be
deemed to be "the day upon which such subdivision becomes effective" or "the day
upon which such combination becomes effective", as the case may be, within the
meaning of paragraph (c) of this Section).

     (g) No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
provided that any adjustment which by reason of this paragraph (g) is not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article shall be made to the
nearest cent or to the nearest 1/100th of a share, as the case may be. No
adjustment in the conversion price shall be required for any increase or
decrease in the par value of the Common Stock.

     (h) In addition to the adjustments in conversion price required by
paragraphs (a), (b), (c), (d), (e) and (f) of this Section, the Company may from
time to time in its discretion make such decreases in the conversion price as it
considers to be advisable, including for purposes of avoiding or diminishing any
Federal income tax to any holders of shares of Common Stock resulting from any
dividend or distribution of stock or issuance of rights or warrants to purchase
or subscribe for stock or from any event treated as such for Federal income tax
purposes or for any other reason.

     (i) Notwithstanding any other provision of this Article XIII, no adjustment
to the conversion price shall result in zero or in a negative number or shall
reduce the conversion price below the then par value per share of the Common
Stock, and any such purported adjustment shall instead reduce the conversion
price to such par value, unless the Common Stock then has no par value, in which
case such purported adjustment shall instead reduce the conversion price to $.01
per share. The Company hereby covenants not to take any action to increase the
par value per share of the Common Stock.

     (j) For the purpose of any computation in this Article, the current market
price per share of Common Stock on any date shall be deemed to be the average of
the closing prices for the 5 consecutive days (on which securities exchanges are
open for trading) preceding such date of determination. The closing price for
each day shall be the last reported sales price regular way or, if no such
reported sale takes place on such day, the average of the reported closing bid
and asked prices regular way, in either case as reported for consolidated
transactions on the New York Stock Exchange or, if the Common Stock is not
listed or admitted to trading on the New York Stock Exchange, on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or, if the Common Stock is not so listed or admitted to trading, on the
Nasdaq Stock Market or, if the Common Stock is not so listed or admitted to
trading, the average of the closing bid and asked prices (or if closing bid and
asked prices or not available, the average of the high bid and low asked prices
for such day) in the over-the-counter market as published by the appropriate
regulatory organization or if not so published as furnished by any New York
Stock Exchange member firm selected from time to time by the Company.

Section 12.5   Notice of Adjustments of Conversion Price.

     Whenever the conversion price is adjusted as herein provided, the Company
shall promptly:

               (i)   compute the adjusted conversion price in accordance with
          Section 12.4 and prepare a certificate signed by the chief financial
          officer or the Treasurer of the Company setting forth the adjusted
          conversion price and showing in reasonable detail the facts upon which
          such adjustment is based, and file such certificate (with a copy to
          the Trustee) at each office or agency maintained for the purpose of
          conversion of Securities pursuant to Section 9.2; and

               (ii)  prepare a notice stating that the conversion price has been
          adjusted and setting forth the adjusted conversion price, and as soon
          as practicable thereafter mail such notice to Holders of Securities
          providing the conversion right contained in this Article XII at their
          last addresses as they shall appear in the Securities Register.

Section 12.6   Trustee's Adjustment Disclaimer.

     The Trustee has no duty to determine when an adjustment under this Article
XII should be made, how it should be made or what it should be. The Trustee
shall not be accountable for and makes no representation as to the validity or
value of any securities or assets issued upon conversion of any Securities. The
Trustee shall not be responsible for the Company's failure to comply with this
Article XII.

Section 12.7   Notice of Certain Corporate Actions.

     In case the Company shall authorize:

               (i)   any event which could result in an adjustment in the
          conversion price under Section 12.4 or require the execution of a
          supplemental indenture under Section 12.12; or

               (ii)  the granting to holders of its Common Stock generally of
          rights, options or warrants to subscribe for or purchase any shares of
          Capital Stock excluding Stockholder Rights); or

               (iii) any reclassification of the Common Stock, or any merger,
          consolidation or share exchange to which the Company is a party and
          for which approval of any stockholders of the Company is required, or
          of the sale or transfer of the properties and assets of the Company
          substantially as an entirety; or

               (iv)  the voluntary or involuntary dissolution, liquidation or
          winding up of the Company;

                                       69

<PAGE>

then the Company shall cause to be filed at each office or agency maintained
pursuant to Section 9.2, and shall cause to be mailed to all Holders of
Securities providing the conversion right contained in this Article XII at their
last addresses as they shall appear in the Security Register, at least 15 days
prior to the applicable record, effective or expiration date hereinafter
specified, a notice stating (A) the date on which a record is to be taken for
the purpose of such dividend, distribution or granting of rights, options or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record who will be entitled to such dividend, distribution,
rights or warrants are to be determined, or (B) the date on which such
reclassification, merger, consolidation, share exchange, sale, transfer,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, merger, consolidation, share
exchange, sale, transfer, dissolution, liquidation or winding up. Neither the
failure to give any such notice nor any defect therein shall affect the legality
or validity of any action described in this Article XII. In case of the
occurrence of any event triggering the exercisability of Stockholder Rights,
then the Company shall cause to be filed at each office or agency maintained
pursuant to Section 9.2, and shall cause to be mailed to the Holders of
Securities providing the conversion right contained in this Article XII at their
last addresses as they shall appear in the Security Register within 10 days
after the occurrence of such event a notice of such event and the date of its
occurrence.

Section 12.8   Company to Reserve Common Stock.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of the authorized but unissued Common Stock or out of the
Common Stock held in treasury, for the purpose of effecting the conversion of
Securities, the full number of shares of Common Stock then issuable upon the
conversion of all outstanding Securities so convertible.

Section 12.9   Taxes on Conversions.

     The Company will pay any and all documentary, stamp or similar issue or
transfer taxes that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of Securities pursuant hereto. The Company shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that of the Holder of the Security or Securities to be converted, and
no such issue or delivery shall be made unless and until the Person requesting
such issue has paid to the Company the amount of any such tax, or has
established to the satisfaction of the Company that such tax has been paid.

Section 12.10  Covenant as to Common Stock.

     The Company covenants that all shares of Common Stock issued upon
conversion of Securities will be validly issued, fully paid and non assessable.

Section 12.11  Cancellation of Converted Securities.

     All Securities delivered for conversion shall be delivered to the Trustee
to be cancelled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 2.12.

Section 12.12  Effect of Merger, Consolidation or Sale of Assets.

     In case of any merger of the Company into or consolidation of the Company
with any other Person, any merger of another Person into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock) or any sale or transfer of
the properties and assets of the Company substantially as an entirety, the
Person resulting from such merger or consolidation or which acquires such
properties and assets of the Company, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security then outstanding shall have the right thereafter, during the
period such Security shall be convertible as specified in Section 12.1, to
convert such Security only into the kind and amount of securities, cash and
other property, if any, receivable upon such merger, consolidation, sale or
transfer by a holder of the number of shares of Common Stock into which such
Security might have been converted immediately prior to such merger,
consolidation, sale or transfer, assuming such holder of Common Stock (i) is not
a Person into which the Company merged or which merged into the Company or with
which the Company consolidated or to which such sale or transfer was made, as
the case may be (a "Constituent Person"), or an Affiliate of a Constituent
Person, and (ii) failed to exercise his rights of election, if any, as to the
kind or amount of securities, cash or other property receivable upon such
merger, consolidation, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such merger, consolidation,
sale or transfer is not the same for each share of Common Stock held immediately
prior to such merger, consolidation, sale or transfer by other than a
Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("nonelecting share"), then for the
purpose of this Section the kind and amount of securities, cash and other
property receivable upon such merger, consolidation, sale or transfer by each
nonelecting share shall be deemed to be the kind and amount so receivable per
share by a plurality of the nonelecting shares). Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date
of such supplemental indenture, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article. The above
provisions of this Section shall similarly apply to any successive merger,
consolidation, sale or transfer. No adjustment in the conversion price shall be
made pursuant to Section 12.4 as a result of any merger, consolidation, sale or
transfer of the properties and assets of the Company substantially as an
entirety to which this Section 12.12 applies.

                                  MISCELLANEOUS

Section 13.1   Compliance Certificates and Opinions.

     Upon any application or request by the Company to the Trustee to take any
action under any provision of this Indenture, the Company shall furnish to the
Trustee such certificates and opinions as may be required under the Trust
Indenture Act or this Indenture. Each such certificate and each such opinion
shall be in the form of an Officers' Certificate or an Opinion of Counsel, as
applicable, and shall comply with the requirements of this Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (i)    a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (ii)   a brief statement as to the nature and scope of the examination
     or investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (iii)  a statement that, in the opinion of each such individual, he
     has made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (iv)   a statement as to whether, in the opinion of each such
     individual, such condition or covenant has been complied with.

     The certificates and opinions provided pursuant to this Section 13.1 and
the statements required by this Section 13.1 shall comply in all respects with
TIA Sections 314(c) and (e).

Section 13.2   Form of Documents Delivered to Trustee.

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an Officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such Opinion of Counsel may be based, insofar as it relates to
factual

                                       72

<PAGE>

matters, upon an Officers' Certificate of an Officer or Officers of the Company
stating that the information with respect to such factual matters is in the
possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate with respect to such matters
is erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

Section 13.3   Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agents duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of authority.
The fact and date of the execution of any such instrument or writing, or the
authority of the Person executing the same, may also be proved in any other
manner which the Trustee deems sufficient.

     (c) The ownership, principal amount and serial numbers of Securities of any
series held by any Person, and the date of holding the same, shall be proved by
the Security Register.

     (d) If the Company shall solicit from Holders of Securities of any series
any request, demand, authorization, direction, notice, consent, waiver or other
Act, the Company may, at its option, by or pursuant to a Board Resolution, fix
in advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding TIA Section
316(c), such record date shall be the record date specified in or pursuant to
such Board Resolution, which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the

                                       73

<PAGE>

purposes of determining whether Holders of the requisite proportion of
Outstanding Securities of a series have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities of a series shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than eleven months after the record date.

     (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

Section 13.4   Notices, etc. to Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with:

          (i)    the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     and delivered in person or mailed by certified or registered mail (return
     receipt requested) to the Trustee at its Corporate Trust Office; or

          (ii)   the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and delivered in person or mailed by certified or registered
     mail (return receipt requested) to the Company addressed to it at the
     Company's principal office located at 810 Houston Street, Fort Worth, Texas
     76102, or at any other address otherwise furnished in writing to the
     Trustee by the Company.

Section 13.5   Notice to Holders; Waiver.

     Where this Indenture provides for notice of any event to Holders by the
Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to each Holder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice. Where this Indenture provides for notice in any manner,
such notice may be waived in writing by the Person entitled to receive such
notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee,

                                       74

<PAGE>

but such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

     In case by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause, it shall be impracticable to mail
notice of any event to Holders when such notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice for every purpose hereunder.

Section 13.6   Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

Section 13.7   Successors and Assigns.

     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not. All agreements of the
Trustee in this Indenture shall bind its successor.

Section 13.8   Separability Clause.

     In case any provision in this Indenture or in the Securities of any series
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby, and a Holder shall have no claim therefore against any party
hereto.

Section 13.9   Benefits of Indenture.

     Nothing in this Indenture or in the Securities of any series, express or
implied, shall give to any Person (other than the parties hereto, any Paying
Agent, any Securities Registrar and their successors hereunder and the Holders)
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

Section 13.10  Governing Law; Trust Indenture Act Controls.

     (a)  THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THE
TRUST INDENTURE ACT IS APPLICABLE. THE COMPANY IRREVOCABLY SUBMITS TO THE
NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT
SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES, AND

     (b) This Indenture is subject to the provisions of the Trust Indenture Act
that are required to be part of this Indenture and shall, to the extent
applicable, be governed by such provisions. If and to the extent that any
provision of this Indenture limits, qualifies or conflicts with the duties
imposed by Sections 310 and 318, inclusive, of the Trust Indenture Act, or
conflicts with any provision (an "incorporated provision") required by or deemed
to be included in this Indenture by operation of such Trust Indenture Act
sections, such imposed duties or incorporated provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or excluded, as the case may
be.

Section 13.11  Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, or Stated
Maturity or Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities of
any series) payment of interest or principal (and premium, if any) need not be
made on such date, but may be made on the next succeeding Business Day with the
same force and effect as if made on the Interest Payment Date, Redemption Date
or at the Stated Maturity or Maturity; provided that no interest shall accrue
for the period from and after such Interest Payment Date, Redemption Date,
Stated Maturity or Maturity, as the case may be.

Section 13.12  No Recourse Against Others.

     A director, officer, employee or stockholder of the Company shall not have
any liability, by reason of his or its status as such director, officer,
employee or stockholder, for any obligations of the Company under the Securities
of any series or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder, by accepting any
Security, waives and releases all such liability to the extent permitted by
applicable law.

Section 13.13  Duplicate Originals.

     The parties may sign any number of copies or counterparts of this
Indenture. Each signed copy shall be an original, but all of them together
represent the same agreement.

Section 13.14  No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or any of its Subsidiaries. Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.

to pay interest thereon, commencing on _______________ and continuing
semiannually thereafter, on __________ and __________ of each year, from
__________, or from the most recent Interest Payment Date to which interest has

principal hereof is paid or duly provided for [if applicable, insert:, and (to
the extent lawful) to pay on demand, interest on any overdue interest at
[_____%] or [the rate borne by the Securities] from the date on which such
overdue interest becomes payable to the date payment of such interest has been
made or duly provided for]. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date

Any such interest not so punctually paid or duly provided for shall forthwith
cease to be payable to the Holder on such Regular Record Date and may be paid to
the Person in whose name this Security (or one or more Predecessor Securities)
is registered at the close of business on a Special Record Date for the payment
of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to

not inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture. Interest on the
Securities of this series shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

                                [Form of Reverse]

     This Security is one of a duly authorized issue of the series of securities
of the Company designated as its [name of designated series] (herein called the
"Securities"), which is issued under, with securities of one or more additional
series that may be issued under, an indenture (herein called the "Indenture")
dated as of ____________, between the Company and The Bank of New York, as
trustee (herein called the "Trustee," which term includes any successor trustee
under the Indenture), to which Indenture and all applicable indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties, obligations and immunities thereunder of
the Company, the Trustee and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered.

     [If applicable, insert as applicable: The Securities are subject to
redemption (1) on __________ of each year commencing with the year ____ and
ending with year ____ through operation of a sinking fund at the Redemption
Prices for redemption through the operation of the sinking fund (expressed as
percentages of the principal amount) set forth in the table below and (2) at the
option of the Company, in whole or in part, at any time on or after
____________, upon not less than 30 or more than 60 days notice at the following
Redemption Prices for redemption otherwise than through operation of the sinking
fund (expressed as percentages of principal amount) set forth in the table
below, if redeemed during the 12-month period beginning on _____________ of the
years indicated below:

                         Redemption Price              Redemption Price
       Year                Sinking Fund                Non Sinking Fund
       ----              ----------------              ----------------

together in the case of any such redemption with accrued and unpaid interest to
the Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date to receive interest due on an Interest Payment Date that is
on or prior to the Redemption Date), all as provided in the Indenture.]

     [If applicable, insert: Securities acquired or redeemed by the Company
otherwise than through sinking fund payments may be credited against subsequent
sinking fund payments otherwise required to be made, in the inverse order in
which they become due.]

     [In the case of any redemption of Securities, interest installments whose
Stated Maturity is on or prior to the Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, of record at
the close of business on the relevant Record Date referred to on the face
hereof. Securities (or portions thereof) for whose redemption and payment
provision is made in accordance with the Indenture shall cease to bear interest
from and after the Redemption Date. In the event of redemption or purchase of
this Security in part only, a

                                       A-4

<PAGE>

new Security or Securities for the unredeemed or unpurchased portion hereof
shall be issued in the name of the Holder hereof upon the cancellation hereof.]

     [If applicable insert: The Securities do not have the benefit of any
sinking fund obligations.]

     As set forth in the Indenture, an Event of Default is generally (a) failure
to pay principal upon maturity, redemption or otherwise; (b) default for 30 days
in payment of interest on any of the Securities; (c) default in the performance
of agreements relating to mergers, consolidations and sales of all or
substantially all assets; (d) failure for 30 days after notice to comply with
any other covenants in the Indenture or the Securities; (e) certain payment
defaults under, the acceleration prior to the maturity of, and the exercise of
certain enforcement rights with respect to, certain Indebtedness of the Company
or any Restricted Subsidiary in an aggregate principal amount in excess of
$10,000,000; (f) certain events giving rise to ERISA liability; (g) certain
final judgments against the Company or any Restricted Subsidiary in an aggregate
amount of $10,000,000 or more which remain unsatisfied and either become subject
to commencement or enforcement proceedings or remain unstayed for a period of 60
days; and (h) certain events of bankruptcy, insolvency or reorganization of the
Company or any Restricted Subsidiary. [If applicable, insert additional events
of default.] If any Event of Default occurs and is continuing, the Trustee or
the holders of at least 25% in aggregate principal amount of the Outstanding
Securities may declare the principal amount of all the Securities to be due and
payable immediately, except that (i) in the case of an Event of Default arising
from certain events of bankruptcy, insolvency or reorganization of the Company
or any Restricted Subsidiary, the principal amount of the Securities will become
due and payable immediately without further action or notice and (ii) in the
case of an Event of Default which relates to certain payment defaults,
acceleration or the exercise of certain enforcement rights with respect to
certain Indebtedness, any acceleration of the Securities will be automatically
rescinded if any such Indebtedness is repaid or if the default relating to such
Indebtedness is cured or waived and if the holders thereof have accelerated such
Indebtedness then such holders have rescinded their declaration of acceleration
or if in certain circumstances the proceedings or enforcement action with
respect to the Indebtedness that is the subject of such Event of Default is
terminated or rescinded. No Holder may pursue any remedy under the Indenture
unless the Trustee shall have failed to act after notice of an Event of Default
and written request by Holders of at least 25% in principal amount of the
Outstanding Securities, and the offer to the Trustee of indemnity reasonably
satisfactory to it; however, such provision does not affect the right to sue for
enforcement of any overdue payment on a Security by the Holder thereof. Subject
to certain limitations, Holders of a majority in principal amount of the
Outstanding Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders notice of any continuing default
(except default in payment of principal, premium or interest) if it determines
in good faith that withholding the notice is in the interest of the Holders. The
Company is required to file quarterly reports with the Trustee as to the absence
or existence of defaults.

     [If applicable insert: The Indenture contains provisions for defeasance at
any time of (i) the entire indebtedness of the Company on this Security and
(ii) certain restrictive covenants

                                      A-5

<PAGE>

and the related Defaults and Events of Default, upon compliance by the Company
with certain conditions set forth therein, which provisions apply to this
Security.]

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Securities at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by or on behalf of the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof whether or not notation of such consent or waiver is made upon
this Security. Without the consent of any Holder, the Company and the Trustee
may amend or supplement the Indenture or the Securities to cure any ambiguity,
defect or inconsistency, to provide for uncertificated Securities in addition to
or in place of Definitive Securities and to make certain other specified changes
and other changes that do not adversely affect the rights of any Holder.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any, on)
and interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registerable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company maintained for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

     The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

     A director, officer, employee or stockholder of the Company shall not have
any personal liability under this Security or the Indenture by reason of his or
its status as such director, officer,

                                      A-6

<PAGE>

employee or stockholder. Each Holder, by accepting this Security, waives and
releases all such liability. Such waiver and release are part of the
consideration for the issuance of this Security.

     Prior to the time of due presentment of this Security for registration of
transfer, the Company, Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security is overdue, and neither the
Company, the Trustee nor any agent shall be affected by notice to the contrary.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture. The Company will furnish to
any Holder upon written request and without charge a copy of the Indenture.
Requests may be made to the Company, 810 Houston Street, Fort Worth, Texas
76102.

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities as a convenience to the Holders thereof. No
representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identifying information
printed hereon.

     This Security shall be governed by and construed in accordance with the
laws of the State of New York, except to the extent the TIA is applicable.
