"Consolidated Net Income" means, with respect to any Person for any period, the aggregate of the Net Income of such Person and its Restricted Subsidiaries, for such period, on a consolidated basis determined in accordance with GAAP; provided, however, that (1) the Net Income, but not loss, of any Person that is not a Restricted Subsidiary or that is accounted for by the equity method of accounting shall be included only to the extent of the amount of dividends or distributions paid in cash to the referent Person or a Restricted Subsidiary; (2) the Net Income of any Restricted Subsidiary shall be excluded to the extent that the declaration or payment of dividends or similar distributions by that Restricted Subsidiary of that Net Income is not at the date of determination permitted without any prior governmental approval, that has not been obtained, or, directly or indirectly, by operation of the terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule or governmental regulation applicable to that Restricted Subsidiary or its stockholders, except in the case of any restriction or encumbrance permitted under clause (a) of Section 4.06; (3) the Net Income of any Person acquired in a pooling of interests transaction for any period prior to the date of such acquisition shall be excluded for purposes of computing the amount of Restricted Payments that the Issuers or their Restricted Subsidiaries may make; and (4) the cumulative effect of a change in accounting principles shall be excluded.

"Disqualified Stock" means any Capital Stock that, by its terms or by the terms of any security into which it is convertible or for which it is exchangeable at the option of the holder of that security, or upon the happening of any event (other than an optional call for redemption by the issuer of that Capital Stock), matures or is mandatorily redeemable, pursuant to a sinking fund obligation or otherwise, or redeemable at the option of the holder of that security, in whole or in part, on or prior to the date on which the notes mature, except to the extent that the Capital Stock is solely redeemable with, or solely exchangeable for, any Capital Stock of that Person that is not Disqualified Stock; provided, however, that any Capital Stock that would not constitute Disqualified Stock but for provisions of that Capital Stock giving holders of that Capital Stock a right to require that Person to repurchase or redeem that Capital Stock upon the occurrence of an "asset sale" or a "change of control" occurring prior to the final maturity date of the applicable notes shall not constitute Disqualified Stock if the "asset sale" or "change of control" provisions applicable to that Capital Stock are no more favorable to the holders of that Capital Stock than the provisions contained in Section 4.07 and Section 4.14 and the Capital Stock specifically provides that the Person will not repurchase or redeem any such Capital Stock pursuant to those "asset sales" or "change of control" provisions prior to the repurchase of any Notes that are required to be repurchased pursuant to Section 4.07 and Section 4.14 and at all times subject to Section 4.03; provided, further, that if an Issuer issues any Capital Stock pursuant to any plan for the benefit of its employees or of employees of its Restricted Subsidiaries, such Capital Stock shall not constitute Disqualified Stock solely because it may be required to be repurchased by such Issuer in order to satisfy applicable statutory or regulatory obligations. Notwithstanding anything herein to the contrary, neither the Series A1 Preferred Stock nor Series A2 Preferred Stock shall constitute Disqualified Stock for any purpose of the Indenture or this First Supplemental Indenture. "Equity Interests" means Capital Stock and all warrants, options or other rights to acquire Capital Stock, but excluding any debt security that is convertible into, or exchangeable for, Capital Stock. "ERISA" means the Employee Retirement Income Security Act of 1974 and regulations promulgated thereunder.

"Hedging Obligations" means, with respect to any Person, the net payment obligations of that Person under (1) interest rate swap agreements, interest rate cap agreements and interest rate collar agreements, and (2) other agreements or arrangements in the ordinary course of business designed to protect that Person against fluctuations in commodity prices, interest rates or currency exchange rates, in any case, not entered into for speculative purposes. "Holding Company Reorganization" means a transaction or a series of transactions resulting in the assets and operations of the Company being held and operated by Finance Sub or its Restricted Subsidiaries; provided, however, that a transaction or a series of transactions shall qualify as a "Holding Company Reorganization" only if it does not result in adverse tax consequences to the Holders or material adverse tax consequence to the Issuers, as determined in good faith by each Issuer's Board of Directors by a resolution set forth in an officers' certificate delivered to the Trustee, which resolution shall be based on an opinion of independent tax counsel of national standing that there will be no adverse tax consequences to the Holders or material adverse consequences to the Issuers. A Holding Company Reorganization may be effected, without limitation, through: (1) a transaction or series of transactions in which the Company contributes all or substantially of its assets and liabilities to Finance Sub which may at any time and from time to time transfer these assets to its Restricted Subsidiaries, but retains its obligations under the notes, or (2) a transaction in which (A) a wholly owned subsidiary of Finance Sub formed solely for the purpose of effecting the Holding Company Reorganization merges with and into the Company, with the Company being the surviving entity and in which Finance Sub becomes the sole holder of all of the issued and outstanding Capital Stock of the surviving entity and all of the holders of the Capital Stock of the Company become the holders of all of the issued and outstanding shares of the Capital Stock of Finance Sub; or (B) the Company merges into a newly-formed limited liability company the sole member of which is Finance Sub as a result of which Finance Sub becomes the sole owner of the limited liability company successor of the Company, and all of the holders of the Capital Stock of the Company, become the holders of all of the issued and outstanding shares of the Capital Stock of Finance Sub. Following the completion of a Holding Company Reorganization, the term "Issuers" will refer only to the holding company resulting from the consummation of the Holding Company Reorganization. "Incur" means create, incur, issue, assume, guarantee or otherwise become liable, directly or indirectly, contingently or otherwise, for any Indebtedness. The term 9 16 "Incurrence" when used as a noun shall have a correlative meaning.

Notwithstanding the foregoing, prior to a Holding Company Reorganization Metricom Finance will not have any of the foregoing obligations unless and to the extent otherwise required by law. (b) The Issuers shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers' Certificate specifying such Default or Event of Default and what action the Issuers are taking or propose to take with respect thereto. SECTION 4.02. RELEASE OF OBLIGATIONS FOLLOWING HOLDING COMPANY REORGANIZATION. Upon consummation of the Holding Company Reorganization, the obligation of (a) Finance Sub with respect to the Notes shall automatically be extinguished and only the Company shall continue as the sole obligor on the Notes, if the 27 34 Holding Company Reorganization is one in which the assets and operations of the Company are transferred to Finance Sub or any of its Restricted Subsidiaries, as contemplated by clause (1) of the definition of Holding Company Reorganization, or (b) the Company with respect to the Notes shall automatically be extinguished and only Finance Sub shall continue as the sole obligor on the Notes, if the Holding Company Reorganization is one in which the assets and operations of the Company remain with the Company or its successor corporation or organization, as contemplated by clause (2) of the definition of Holding Company Reorganization; provided, however, that upon consummation of the Holding Company Reorganization, the Company's guarantee of Finance Sub's obligations with respect to the Notes shall automatically, and without further notice to or action by the Holders, be extinguished and shall cease to be of any further force or effect. In that event, the Trustee shall, at the request of either obligor, enter into a Supplemental Indenture to evidence the release of the Company or Finance Sub, as the case may be, from its obligations on the notes, and the release of the Company from its guarantee of Finance Sub's obligations with respect to the Notes. SECTION 4.03. LIMITATION ON RESTRICTED PAYMENTS. The Issuers shall not make, and shall not permit any Restricted Subsidiary to make, directly or indirectly a Restricted Payment, unless, at the time of and after giving effect to that Restricted Payment: (1) no Default or Event of Default will have occurred and be continuing or would occur as a consequence of the Restricted Payment; (2) the Issuers would, at the time of the Restricted Payment and after giving pro forma effect to the Restricted Payment as if it had been made at the beginning of the applicable Reference Period, have been permitted to incur at least $1.00 of additional Indebtedness under the Consolidated Leverage Ratio test set forth in the first paragraph of Section 4.04 hereof; and (3) the Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Issuers or any of their Restricted Subsidiaries after the date hereof are issued, excluding Restricted Payments permitted by clauses (ii), (iii), (iv) or (v) of the immediately following paragraph below, is less than the sum of: (a) the amount by which Consolidated Cash Flow exceeds 1.5 times Consolidated Fixed Charges for the period from the first day of the calendar quarter in which the Notes are issued through the end of the last completed fiscal quarter for which consolidated financial statements for the Issuers are publicly available; plus (b) 100% of the aggregate net cash proceeds received by the Issuers from the issue or sale since the date hereof of (I) Equity Interests, other than Disqualified Stock, of the Issuers, except to the extent any such net cash proceeds are relied upon to incur Indebtedness pursuant to clause (10) of the definition of the term Permitted Debt or used to make Permitted Investments pursuant to clause (8) of the definition of the term Permitted Investment, and (II) Disqualified Stock or convertible debt securities of the Issuers to the extent converted into Equity Interests, other than Disqualified Stock, and in any case other than Equity Interests, Disqualified Stock or convertible debt securities sold to a Restricted Subsidiary; plus (c) to the extent not already included in Consolidated Cash Flow for the Issuers for the relevant period, without duplication, if any Restricted Investment that was made by the Issuers or any of their Restricted Subsidiaries after the date hereof is sold for cash or otherwise liquidated or repaid for cash, the lesser of: (I) the cash return of capital with respect to the Restricted 28 35 Investment, less the cost of disposition, if any; and (II) the initial amount of the Restricted Investment; plus (d) to the extent not already included in Consolidated Cash Flow for the Issuers the relevant period, without duplication, an amount equal to the net reduction in Restricted Investments made by the Issuers or any of their Restricted Subsidiaries from the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary not to exceed the lesser of: (I) the amount of the Restricted Investment, valued in each case as provided under Section 4.13 hereof, previously made by the Issuers or any of their Restricted Subsidiaries in that Unrestricted Subsidiary, which amount was included in the calculation of the amount of Restricted Payments associated with that Restricted Investment, and (II) the fair market value of the Investment by the Issuers or their Restricted Subsidiaries in the Unrestricted Subsidiary at the time of the redesignation. The foregoing provision will not be violated by reason of: (i) the payment of any dividend with respect to any Equity Interests of the Issuers or their Restricted Subsidiaries within 60 days after the date of its declaration if the payment would comply with the foregoing paragraph at the date of its declaration; (ii) the payment of dividends with respect to the Series A1 Preferred Stock and Series A2 Preferred Stock through November 15, 2002 in accordance with the terms of those securities as of the date hereof; (iii) the redemption, repurchase, defeasance or other acquisition or retirement for value of Equity Interests of the Issuers or any Indebtedness that is subordinated to the Notes, in each case in exchange for, or out of the net cash proceeds of the substantially concurrent sale, other than to a Restricted Subsidiary of an Issuer of, Equity Interests of an Issuer, other than Disqualified Stock; provided, however, that the amount of any net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause (b) of the preceding paragraph; (iv) the defeasance, redemption, repurchase or other acquisition or retirement of Indebtedness which is subordinated to the Notes with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; (v) the payment of any dividend or distribution by any Restricted Subsidiary of an Issuer, including Finance Sub, to the holders of such Restricted Subsidiary's Common Stock so long as that dividend or distribution is paid to all holders of the Common Stock of that Restricted Subsidiary pro rata in accordance with their interests; (vi) payments or distributions to dissenting stockholders pursuant to applicable law, pursuant to or in connection with a consolidation, merger or transfer of assets that complies with the provisions of Section 5.01 of the Indenture and Section 5.01 of this First Supplemental Indenture; (vii) cash payments in lieu of the issuance of fractional shares in connection with the exercise of any warrants, options or other securities convertible into or exchangeable for Common Stock of an Issuer or of a Restricted Subsidiary of an Issuer; (viii) the purchase, redemption, acquisition, cancellation or other retirement for value of shares of Capital Stock of an Issuer or any Restricted Subsidiary of an Issuer to the extent required by FCC rules, other comparable foreign telecommunications authorities or any other governmental agencies in order to prevent the loss or secure the renewal or reinstatement of any license or franchise held by the Issuers or any Restricted Subsidiary; (ix) the purchase by the Issuers or a Restricted Subsidiary of Equity Interests, other than with respect to Disqualified Stock, in a 29 36 Restricted Subsidiary from employees, officers or directors of that Restricted Subsidiary in connection with the termination of their employment with such Restricted Subsidiary; provided that the Equity Interests so repurchased are not Capital Stock of, or Equity Interests to acquire Capital Stock of, a class that is listed on a national securities exchange or admitted for trading in the National Market of the Nasdaq Stock Market; provided further that the amount of all Restricted Payments made pursuant to this clause (ix) do not exceed $2.5 million in any calendar year or $10.0 million in the aggregate; (x) other Restricted Payments in an aggregate amount not to exceed $5.0 million; and (xi) the repurchase of Subordinated Debt at a purchase price not greater than 101% of the principal or accreted amount thereof, plus accrued and unpaid interest, if any, pursuant to a mandatory offer to repurchase made after a Change of Control; provided, however, that the Issuers shall have first made any Change of Control Offer and repurchased all tendered notes pursuant to Section 4.14 hereof; provided, further, that except for clauses (i), (v), (vii) and (viii), no Default or Event of Default shall have occurred and be continuing or occur as a consequence of the Restricted Payment. The amount of all Restricted Payments, other than cash, will be the fair market value on the date the Restricted Payment is made of the assets or securities proposed to be transferred or issued by the Issuers or any Restricted Subsidiary pursuant to the Restricted Payment. The fair market value of any non-cash Restricted Payment will be determined by each Issuer's Board of Directors in good faith, whose resolution will be delivered to the Trustee, and its determination will be based upon an opinion or appraisal issued by an investment banking firm, appraisal firm or accounting firm, in each case of national standing, if the fair market value exceeds $15.0 million. Not later than the date of making any Restricted Payment, the Issuers will deliver to the Trustee an Officers' Certificate stating that the Restricted Payment is permitted and setting forth the basis hereof, unless all payments due under the Indenture or this First Supplemental Indenture with respect to the Notes, and the applicable Notes, are secured on an equal and ratable basis with (or if the obligations being secured rank junior in right of payment to the Notes, on a senior basis to) the obligations so secured until such time as such obligations are no longer secured by a Lien, provided, however, in no event will the Issuers or their Restricted Subsidiaries be permitted at any time to have Liens securing more than $700 million principal amount of Indebtedness. SECTION 4.04. LIMITATION ON INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness (including Acquired Debt) and the Issuers will not issue any Disqualified Stock and will not permit any of their Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however, that the Issuers may Incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and any of their Restricted Subsidiaries may Incur Indebtedness if the incurrence results in a Consolidated Leverage Ratio that is no greater than 7.0 to 1.0 if the Indebtedness is Incurred or the Disqualified Stock is issued prior to February 1, 2005, or 6.0 to 1.0 thereafter. Notwithstanding the foregoing, as long as no Default or Event of Default shall have occurred and be continuing, the Issuers and, except 30 37 as specified in the definition of Permitted Debt, any of their Restricted Subsidiaries may Incur Permitted Debt. Notwithstanding any other provision of this Section 4.04, including the definition of Permitted Debt, the Issuers and their Restricted Subsidiaries may Incur the U.S. dollar equivalent of any Indebtedness in a foreign currency and the maximum amount of Indebtedness that the Issuers or a Restricted Subsidiary may incur pursuant to this covenant will not be deemed to be exceeded with respect to any outstanding Indebtedness due solely to the result of subsequent fluctuations in the exchange rates of currencies. For purposes of determining compliance with this Section 4.04, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (11) of the definition of Permitted Debt or would be entitled to be Incurred pursuant to the first paragraph of this Section 4.04, at the date of Incurrence, the Issuers, in their sole discretion, shall classify and from time thereafter may reclassify, in whole or in part, that item of Indebtedness in any manner that complies with this Section 4.04. Accrual of interest, accretion of accreted value and the payment of interest in the form of additional Indebtedness shall not be deemed an Incurrence of Indebtedness for purposes of this Section 4.04. In addition, for purposes of determining any particular amount of Indebtedness under this Section 4.04, neither (A) Guarantees, Liens or obligations with respect to letters of credit supporting Indebtedness otherwise included in the determination of such particular amount, or (B) any Liens granted pursuant to the equal and ratable provisions referred to in Section 4.05 hereof, will be included. SECTION 4.05. LIMITATION ON LIENS. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Indebtedness, Attributable Debt or trade payables, other than Permitted Liens, upon any of the Issuers' or their Restricted Subsidiaries' property or assets, now owned or acquired after the date hereof, unless all payments due under the Indenture or this First Supplemental Indenture with respect to the Notes, and the applicable Notes, are secured on an equal and ratable basis with (or if the obligations being secured rank junior in right of payment to the Notes, on a senior basis to) the obligations so secured until such time as such obligations are no longer secured by a Lien; provided, however, in no event will the Issuers or their Restricted Subsidiaries be permitted at any time to have Liens securing more than $700 million principal amount of Indebtedness. SECTION 4.06. LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES. For so long as any of the Notes are outstanding, the Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction of any kind on the ability of any Restricted Subsidiary to: (1) pay dividends or make any other distributions to the Issuers or any of their Restricted 31 38 Subsidiaries on any Capital Stock or with respect to any other interest or participation in, or measured by, profits; (2) pay any Indebtedness owed to the Issuers or any of their Restricted Subsidiaries; (3) make loans or advances to the Issuers or any Restricted Subsidiary; or (4) transfer any property or assets of a Restricted Subsidiary to the Issuers or any Restricted Subsidiary. The foregoing provisions shall not restrict any encumbrances or restrictions: (a) contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in that Indebtedness or agreement and such encumbrance or restriction is not materially more disadvantageous to the Holders than is customary in comparable financings, as determined by each Board of Directors of the Issuers, in good faith, and such Boards of Directors determine in good faith that any such encumbrance or restriction is not reasonably likely to materially affect the Issuers' ability to make principal or interest payments on the Notes; (b) existing under or by reason of applicable law; (c) existing with respect to any Person, or the property or assets of that Person, acquired by the Issuers or any Restricted Subsidiary existing at the time of the acquisition and not incurred in contemplation of the acquisition, which encumbrances or restrictions are not applicable to any Person or the property or assets of any Person other than the acquired Person or the property or assets of the Person so acquired, provided that, in the case of encumbrances and restrictions with respect to Acquired Indebtedness, that Indebtedness was permitted to be incurred under the Indenture and this First Supplemental Indenture; (d) in the case of clause (4) (and, in case of subparagraph (II) below to the extent relating to the sale of all of an Issuer's Capital Stock in, or all or substantially all the assets of, a Restricted Subsidiary, clause (1)) of the first paragraph of this Section 4.06, (I) that restrict in a customary manner the subletting, assignment or transfer of any property or asset that is, or is subject to, a lease, purchase mortgage obligation, license, conveyance or similar agreement or instrument; (II) existing by virtue of any transfer of, agreement to transfer, option or right with respect to, or Lien on, any of the property or assets of the Issuers of any Restricted Subsidiary not otherwise prohibited by the Indenture or this First Supplemental Indenture, or (III) arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of the property or assets of the Issuers or of any Restricted Subsidiary in any manner material to the Issuers or any Restricted Subsidiary; (e) existing under purchase money obligations that impose restrictions of the nature described in clause (4) above on the property so acquired; (f) existing under Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing the Permitted Refinancing Indebtedness are no more restrictive than those contained in the agreements governing the Indebtedness being refinanced; or (g) provisions in joint venture and other similar agreements entered into in the ordinary course of business that prohibit actions of the type described in clauses (1), (3) or (4) above unless the joint venture or similar entity satisfies net worth or other operating or financial performance standards customary in these types of agreements, as determined by each Board of Directors of the Issuers in good faith. 32 39 Nothing contained in this Section 4.06 will prevent the Issuers or any Restricted Subsidiary from: (A) creating, incurring, assuming or suffering to exist any Liens otherwise permitted by Section 4.05; or (B) restricting the sale or other disposition of property or assets of the Issuers or any of their Restricted Subsidiaries that secure Indebtedness of the Issuers or any of their Restricted Subsidiaries. SECTION 4.07. LIMITATION ON SALE OF ASSETS. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, consummate an Asset Sale, unless (1) the Issuers or such Restricted Subsidiary receive consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of, as determined in good faith by the Board of Directors of each Issuer, whose determination will be conclusive, and in each case where the fair market value is greater than $10.0 million, evidenced by a Board Resolution and set forth in an Officers' Certificate delivered to the Trustee; and (2) at least 75% of the consideration received by the Issuers or such Restricted Subsidiary for the Asset Sale consists of cash or Cash Equivalents; provided, however, that the amount of: (a) any liabilities of (I) the Issuers, as shown on the most recent balance sheet, other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or (II) any Restricted Subsidiaries, as shown on the most recent consolidated balance sheet, other than contingent liabilities or liabilities that are by their terms subordinated to any guarantees of the Notes, in each case that are assumed by the transferee in the Asset Sale pursuant to a customary novation agreement that releases the Issuers or such Restricted Subsidiary, as applicable, from further liability, and (b) any securities, notes or other obligations received by the Issuers or such Restricted Subsidiary from the transferee in the Asset Sale that are converted into cash or Cash Equivalents within 30 days, to the extent of the cash or Cash Equivalents received in that conversion, shall be treated as cash for purposes of this clause (2). The Issuers shall, or shall cause the relevant Restricted Subsidiary to, within 360 days after the date of receipt of the Net Proceeds from an Asset Sale, at the option of the Issuers either apply these Net Proceeds (a) to permanently repay, and reduce the amount permitted to be borrowed under, any of the Issuers' Indebtedness secured by a Lien or any Indebtedness of one or more of the Issuers' Restricted Subsidiaries, or (b) acquire a controlling interest in, or all or substantially all the assets of, another Communications and Data Access Business, make a capital expenditure in assets used or to be used in a Communications and Data Access Business or acquire other long-term assets that are used or are to be used in a Communications and Data Access Business. Pending the final application of any Net Proceeds from an Asset Sale, the Issuers may temporarily reduce Indebtedness under any revolving Credit Facility or otherwise invest those Net Proceeds in any manner that is not prohibited by the Indenture 33 40 or this First Supplemental Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided above will be deemed to constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Issuers shall make an offer to all Holders and holders of any other Indebtedness that ranks equally in right of payment with the Notes and that requires the Issuers to make such an offer (an "Asset Sale Offer") to purchase the maximum principal amount or principal amount at maturity, as applicable, of Notes and other Indebtedness that ranks equally in right of payment with the Notes that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to the purchase date. If the aggregate amount of Notes and other Indebtedness ranking equally with the Notes tendered in an Asset Sale Offer exceeds the amount of Excess Proceeds, the Holders validly accepting the Asset Sale Offer will be entitled to receive their pro rata portion of the Excess Proceeds (calculated for each Holder based on the ratio of the principal amount of the Notes tendered by such Holder to the total principal amount of Notes, or principal amount at maturity of all other Indebtedness tendered in respect of such Asset Sale Offer). Following the completion of an Asset Sale Offer, the amount of Excess Proceeds remaining, if any, will be deemed to be zero. To the extent that the aggregate amount of Notes and other Indebtedness tendered in response to an Asset Sale Offer is less than the Excess Proceeds, the Issuers may use any remaining Excess Proceeds for any purpose not prohibited by the Indenture and this First Supplemental Indenture. SECTION 4.08. LIMITATION ON TRANSACTIONS WITH AFFILIATES. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuers or any of their Restricted Subsidiaries (each of the foregoing, an "Affiliate Transaction"), unless (1) the Affiliate Transaction is on terms that are no less favorable to the Issuers or such Restricted Subsidiary than terms that would have been obtained in a comparable transaction by the Issuers or such Restricted Subsidiary with an unrelated Person and (2) the Issuers deliver to the Trustee (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, a resolution of the Board of Directors of each Issuer set forth in an Officers' Certificate certifying that the Affiliate Transaction complies with clause (1) above and that the Affiliate Transaction has been approved by a majority of the disinterested members of each Board of Directors and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15.0 million, an opinion or appraisal as to the fairness to the Issuers or such Restricted Subsidiary of the Affiliate Transaction from a financial 34 41 point of view, issued by an investment banking firm, appraisal firm or accounting firm, in each case of national standing. The foregoing limitation does not limit, and will not apply to: (I) any employment agreement entered into by the Issuers or any of their Restricted Subsidiaries in the ordinary course of business; (II) transactions between or among the Issuers and/or their Restricted Subsidiaries; (III) Restricted Payments that are permitted by Section 4.03; (IV) fees and compensation paid to members of the Boards of Directors of the Issuers and their Restricted Subsidiaries in their capacity as such, to the extent such fees and compensation are reasonable and customary; (V) reasonable advances to employees for moving, entertainment and travel expenses, and similar expenditures in the ordinary course of business; (VI) fees and compensation paid to, and indemnity provided on behalf of, officers, directors or employees of the Issuers or any of their Restricted Subsidiaries, as determined by the Board of Directors of each Issuer or of any such Restricted Subsidiary, to the extent those fees and compensation are reasonable and customary; (VII) the MCI WorldCom Reseller Agreement as in effect on the date hereof; (VIII) any agreement similar to the MCI WorldCom Reseller Agreement entered into with any Affiliate of the Issuers or of their Restricted Subsidiaries on terms not more favorable to such party than the terms of the MCI WorldCom Reseller Agreement, as in effect immediately before the effective time of any such similar agreement; (IX) compliance by the Company with its obligations under the outstanding Series A1 Preferred Stock and Series A2 Preferred Stock, as the same exist on the date hereof; (X) the consummation of the Holding Company Reorganization; (XI) any sale or other issuance of Equity Interests, other than in respect of Disqualified Stock; or (XII) commercial, technical and similar agreements or transactions related to the provision of services by the Issuers or their Restricted Subsidiaries or related to the acquisition of goods and services by the Issuers or their Restricted Subsidiaries, in any case entered into in the ordinary course of business; provided, however, that the terms of such agreements or transactions are no less favorable to the Issuers than terms that 35 42 would have been obtained in a comparable transaction by the Issuers or their Restricted Subsidiaries with an unrelated Person. SECTION 4.09. LIMITATION ON SALE AND LEASEBACK TRANSACTIONS. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction; provided, however, that the Issuers and their Restricted Subsidiaries may enter into a Sale and Leaseback Transaction if (1) the Issuers or such Restricted Subsidiary could have Incurred Indebtedness in an amount equal to the Attributable Debt relating to the Sale and Leaseback Transaction pursuant to Section 4.04 hereof; (2) the gross cash proceeds of the Sale and Leaseback Transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors of each Issuer and set forth in an Officers' Certificate delivered to the Trustee, of the property that is the subject of the Sale and Leaseback Transaction; and (3) the transfer of assets in the Sale and Leaseback Transaction is permitted by, and the Issuers apply the proceeds of the transaction in compliance with, Section 4.07. SECTION 4.10. LIMITATION ON ISSUANCE OF GUARANTEES OF INDEBTEDNESS BY RESTRICTED SUBSIDIARIES. The Issuers shall not permit any Restricted Subsidiary, directly or indirectly, to guarantee, assume or in any other manner become liable with respect to any of Indebtedness of the Issuers that ranks equally in right of payment with, or junior in right of payment to the Notes unless: (1) that Restricted Subsidiary simultaneously executes and delivers a Supplemental Indenture to the Indenture providing for a guarantee of the Notes on terms substantially similar to the guarantee of such Indebtedness, along with a notation relating to such guarantee in substantially the form of Exhibit E hereto, except that if such Indebtedness is by its express terms subordinated in right of payment to the Notes, any such assumption, guarantee or other liability of such Restricted Subsidiary with respect to such Indebtedness will be subordinated in right of payment to such Restricted Subsidiary's assumption, guarantee of other liability with respect to the Notes substantially to the same extent as such Indebtedness is subordinated to the Notes, and (2) that Restricted Subsidiary waives, and will not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against the Issuers or any of their Restricted Subsidiaries as a result of any payment by such Restricted Subsidiary under its guarantee. 36 43 Notwithstanding the foregoing, any guarantee by a Restricted Subsidiary may provide by its terms that it will be automatically and unconditionally released and discharged upon (a) any sale, exchange or transfer, to any Person not an Affiliate of the Issuers, of all of the Capital Stock of the Issuers and their Restricted Subsidiaries in, or all or substantially all of the assets of, such Restricted Subsidiary, which sale, exchange or transfer is not prohibited by the Indenture or this First Supplemental Indenture; provided, however, that the Person to which that Capital Stock is sold does not, directly or indirectly, guarantee, assume or in any other manner become liable with respect to any Indebtedness of the Issuers as a result of or in connection with the sale, exchange or transfer, or (b) the release or discharge of the Indebtedness which resulted in the creation of that guarantee, except a discharge or release by or as a result of payment under such guarantee. SECTION 4.11. LIMITATION ON BUSINESS ACTIVITIES. The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, directly or indirectly, engage in any line of business other than a Communications and Data Access Business, except to such extent as would not be material to the Issuers and their Restricted Subsidiaries taken as a whole. SECTION 4.12. LIMITATION ON ISSUANCE AND SALE OF EQUITY INTERESTS OF RESTRICTED SUBSIDIARIES. Other than in connection with the Holding Company Reorganization, the Issuers shall not sell, transfer, convey or otherwise dispose of and shall not permit any Restricted Subsidiary, directly or indirectly, to issue, sell, transfer, convey or otherwise dispose of any Equity Interests of such Restricted Subsidiary or any other Restricted Subsidiary to any Person, except: (1) to the Issuers or any of their Restricted Subsidiaries; (2) issuances of director's qualifying shares or sales to foreign nationals of shares of Capital Stock of non-U.S. Restricted Subsidiaries to the extent required by law; and (3) issuances and sales of Equity Interests in respect of Common Stock of Restricted Subsidiaries effected in compliance with Section 4.07 hereof or in a transaction excluded from the definition of the term "Asset Sale"; provided, however, that, if, after giving effect to such issuance or sale, that Restricted Subsidiary would cease to be a Subsidiary of the Issuers, then the Issuers shall not effect, or permit their Restricted Subsidiary, to effect such issuance or sale unless any remaining Investment in such Person would have been permitted to be made (and shall be treated as a Restricted Investment) under Section 4.03 hereof, with the value of such remaining Investment to be determined in the manner prescribed by the last sentence of the first paragraph of Section 4.13 hereof. SECTION 4.13. DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES. For so long as no Default or Event of Default has occurred and is continuing, the Board of Directors of the Company prior to a Holding Company Reorganization and the Board of Directors of Finance Sub, after a Holding Company 37 44 Reorganization will be permitted to designate any Restricted Subsidiary to be an Unrestricted Subsidiary; provided, however, that the Issuers could incur, immediately after that designation, $1.00 of Indebtedness under the Consolidated Leverage Ratio test set forth in the first paragraph of Section 4.04 hereof as though such designation had occurred at the beginning of the Reference Period. In the event that the Issuers designate a Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Issuers and their Restricted Subsidiaries, except to the extent repaid in cash, in the Restricted Subsidiary so designated will be deemed to be an Investment at the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.03 hereof or otherwise available as a Permitted Investment, as applicable. All of these outstanding Investments will be valued at an amount equal to the greater of: (1) the fair market value of those Investments at the time of the designation; and (2) the original fair market value of those Investments at the time they were made. The Issuers shall only be permitted to designate a Restricted Subsidiary as an Unrestricted Subsidiary if the Restricted Payment or an equivalent Permitted Investment would be permitted at that time and if the Restricted Subsidiary otherwise would meet the definition of an Unrestricted Subsidiary. Any designation by the Board of Directors of the Company, prior to a Holding Company Reorganization, and the Board of Directors of Finance Sub, after a Holding Company Reorganization, of a Restricted Subsidiary as an Unrestricted Subsidiary will be required to be evidenced by the filing with the Trustee of a certified copy of the Board Resolution giving effect to the designation and an Officers' Certificate certifying that the designation complied with the foregoing conditions. If, at any time, any Unrestricted Subsidiary would fail to meet the definition of an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and this First Supplemental Indenture and any Indebtedness of that Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of that date and, if the Indebtedness is not permitted to be Incurred as of that date under Section 4.04 hereof, the Issuers will be in default of such Section 4.04. The Board of Directors of the Company, prior to a Holding Company Reorganization, and the Board of Directors of Finance Sub, after a Holding Company Reorganization, will be permitted to at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided, however, that the designation will be deemed to be an Incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of the Unrestricted Subsidiary and the designation will only be permitted if (a) the Indebtedness is permitted under the first paragraph of Section 4.04 hereof, and (b) no Default or Event of Default would be in existence immediately following such designation. 38 45 SECTION 4.14. CHANGE OF CONTROL. Upon the occurrence of a Change of Control, each Holder will have the right to require the Issuers to repurchase all or any part of such Holder's Notes pursuant to the Change of Control Offer described below at a purchase price in cash (the "Change of Control Payment") equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest to the Change of Control Payment Date. Within 10 days following any Change of Control, the Issuers shall mail a notice to the Trustee and each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase the Notes (the "Change of Control Offer") on the date specified in the notice, which will not be earlier than 30 days or later than 60 days from the date the notice is mailed (the "Change of Control Payment Date"). On the Change of Control Payment Date, the Issuers shall, to the extent lawful: (a) accept for payment Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer; (b) deposit with the Paying Agent an amount equal to the Change of Control Payment for all Notes or portions thereof so accepted; and (c) deliver, or cause to be delivered, to the Trustee, all Notes or portions thereof so accepted together with an Officers' Certificate specifying the Notes or portions thereof that accepted for payment. The Paying Agent promptly shall mail the Change of Control Payment due to the Holders accepted for purchase. The Trustee shall promptly authenticate and mail or cause to be transferred by book entry to the Holders a new Note equal in principal amount of any unpurchased portion of the Notes surrendered. In any event, each Note that is purchased and each new Note that issued will be in a principal amount of $1,000 or integral multiples thereof. The Issuers shall announce publicly the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. The Change of Control provisions described in this Section 4.14 will be applicable whether or not any other provisions of the Indenture and this First Supplemental Indenture are applicable. Except as described in this Section 4.14, the Indenture and First Supplemental Indenture do not contain provisions that permit the Holders to require the Issuers to repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction. The Issuers shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture and this Supplemental Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under that Change of Control Offer. 39 46 The Issuers shall comply with Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent those laws and regulations are applicable in the event that a Change of Control occurs and the Issuers are required to offer to repurchase the Notes under this Section 4.14. In the event of a conflict between complying with applicable laws and the provisions of the Indenture and this First Supplemental Indenture, the Issuers shall comply with applicable laws and shall not be deemed to have committed a Default or Event of Default as a result of so complying. ARTICLE 5 SUCCESSORS SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS. The Issuers shall not, directly or indirectly, consolidate or merge with or into, whether or not an Issuer is the surviving corporation, or sell, assign, transfer, convey or otherwise dispose of all or substantially all of the Issuers' properties or assets in one or more related transactions, to another Person unless (1) an Issuer is the surviving corporation or the Person formed by or surviving the consolidation or merger, if other than an Issuer, or to which the sale, assignment, transfer, conveyance or other disposition is made is organized under the laws of the United States or any state of the United States or the District of Columbia, the British Virgin Islands, Cayman Islands, The Netherlands, Ireland, Jersey or Luxembourg; (2) the Person formed by or surviving the consolidation or merger, if other than an Issuer, or the Person to which the sale, assignment, transfer, conveyance or other disposition is made assumes all of the Issuers' obligations under the Notes and the Indenture and this First Supplemental Indenture pursuant to a Supplemental Indenture in a form reasonably satisfactory to the Trustee; (3) immediately before and after the transaction no Default or Event of Default will have occurred; (4) in the event that the continuing Person is incorporated in a jurisdiction other than under the laws of the United States or any state of the United States or the District of Columbia: (a) the Issuers deliver to the Trustee an opinion of counsel stating that the obligations of the continuing person under the Indenture and this First Supplemental Indenture are enforceable under the laws of the new jurisdiction of its incorporation to the same extent as the Issuers' obligations under the Indenture and this First Supplemental Indenture immediately prior to the transaction; (b) the continuing Person agrees in writing to submit to jurisdiction and appoints an agent for the service of process, each under terms substantially similar to the terms contained in the Indenture and this First Supplemental Indenture with respect to the Issuers; (c) the continuing Person agrees in writing to pay Additional Amounts with respect to any withholding tax imposed by the country of the continuing Person's organization or any political subdivision thereof, and such Additional Amounts will relate to any 40 47 withholding tax whatsoever regardless of any change of law, subject to exceptions set forth below under Section 5.03 hereof; and (d) the Board of Directors of the Company, prior to a Holding Company Reorganization, or Finance Sub, after a Holding Company Reorganization, determines in good faith that the transaction is not reasonably likely to have a material adverse effect on the Holders and a Board Resolution to that effect is delivered to the Trustee; and (5) except in the case of the Holding Company Reorganization, an Issuer or the Person formed by or surviving the consolidation or merger, if other than an Issuer, or to which the Issuers sell, assign, transfer, convey or otherwise dispose of all or substantially all their properties or assets, will, immediately after the transaction after giving pro forma effect to the transaction and any related financing transactions as if the same had occurred at the beginning of the applicable Reference Period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Leverage Ratio test set forth in the first paragraph of Section 4.04 hereof. In addition, the Issuers shall not, directly or indirectly, lease all or substantially all of their properties or assets, in one or more related transactions, to any other Person. Notwithstanding the foregoing provisions, nothing in this Section 5.01 shall prohibit the Issuers from completing the Holding Company Reorganization, provided that the completion of that transaction is solely for the purpose of effecting the Holding Company Reorganization and not for the purpose of circumventing any other provision of the Indenture or this First Supplemental Indenture. SECTION 5.02. SUCCESSOR CORPORATION SUBSTITUTED. Upon any consolidation or merger, or any sale, assignment, transfer, conveyance or other disposition of all or substantially all of the Issuers' assets in accordance with the foregoing provisions in which an Issuer is not the continuing obligor under the Notes and the Indenture and First Supplemental Indenture, the surviving entity will succeed to, and be substituted for, and may exercise every right and power of, the Issuers under the Notes, Indenture and the First Supplemental Indenture with the same effect as if that successor had been named as an Issuer in the Notes, Indenture and First Supplemental Indenture. When a successor assumes all the obligations of its predecessor under the Notes, Indenture and First Supplemental Indenture, the predecessor will be released from those obligations. SECTION 5.03. ADDITIONAL AMOUNTS. The Issuers shall pay to each Holder such additional amounts ("Additional Amounts") as may be necessary in order that every net payment of the principal of and interest on such Holder's Notes, after deduction or withholding for or on account of any present or future tax, assessment or governmental charge imposed upon or as a result of such payment by the country in which the continuing Person is organized or any political subdivision or taxing authority in that political subdivision or taxing authority, will not be less than the amount provided 41 48 for in such Notes, then due and payable before any such tax, assessment or other governmental charge; provided, however, that the foregoing obligation to pay Additional Amounts shall not apply to: (a) any tax, assessment or other governmental charge which would not have been so imposed but for: (i) the existence of any present or former connection between such Holder (or between a fiduciary, settler, beneficiary, member, partner or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the country in which the Issuers are organized, including, without limitation, such Holder (or such fiduciary, settler, beneficiary, member, partner, shareholder or possessor) being or having been a citizen or resident of the country in which the Issuers are organized or treated as a resident thereof, or being or having been engaged in trade or business or present therein, or having or having had a permanent establishment therein or making or having made an election the effect of which is to subject such Holder or beneficial owner (or such fiduciary, settler, beneficiary, member, partner, shareholder or possessor) to such tax assessment or other governmental charge; (ii) the failure of such Holder or beneficial owner of a Note to comply with any requirement under income tax treaties, statutes and regulations or administrative practice of the country in which the Issuers are organized, to establish entitlement to exemption from or reduction of such tax, assessment or other governmental charge; or (iii) such Holder's present or former status as a personal holding company or foreign personal holding company with respect to the United States, a controlled foreign corporation or a passive foreign investment company for United States tax purposes or a corporation that accumulates earnings to avoid United States federal income tax; (b) any tax, assessment or other governmental charge which would not been so imposed but for the presentation by the Holder of such Note for payment on a date more than 10 days after the date on which such payment becomes due and payable or a date on which payment thereof is duly provided for and notice is given to Holders, whichever occurs later; (c) any estate, inheritance, gift, sales, transfer, personal property or similar tax, assessment or governmental charge; (d) any tax, assessment or other governmental charge which is payable otherwise than by deduction or withholding from payments of principal of or interest on such Note; 42 49 (e) any tax, assessment or other governmental charge which is payable by a Holder that is not the beneficial owner of the Note, or a portion of the Note, or that is a foreign or fiduciary partnership, but only to the extent that a beneficial owner, settler with respect to such fiduciary or member of the partnership would not have been entitled to the payment of an Additional Amount had the beneficial owner or member received directly its beneficial or distributive share of the payment; (f) any tax, assessment or other governmental charge required to be withheld by any Paying Agent from any payment of the principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or (g) any combination of items (a) through (f) above. For the purposes of the foregoing, the holding of or the receipt of any payment with respect to a Note will not constitute a connection between the Holder (or between a fiduciary, settler, beneficiary, member, partner or shareholder of, or a person having a power over, such Holder if such Holder is an estate, a trust, a partnership or a corporation) and the country in which the Issuers are organized. Except as specifically provided herein, the Issuers shall not be required to make any payment with respect to any tax, assessment or other governmental charge imposed by any government or any political subdivision or taxing authority thereof or therein. References in the Indenture and this First Supplemental Indenture to principal and/or interest shall be deemed also to refer to any Additional Amounts which may be payable under this provision. ARTICLE 6 DEFAULTS AND REMEDIES SECTION 6.01. EVENTS OF DEFAULT. Each of the following shall constitute an "Event of Default" for purposes of the Indenture and this First Supplemental Indenture: (1) default in the payment of interest on the Notes when due and payable and, other than with respect to the first four scheduled interest payments on the Notes, continuance of such default for a period of 30 days; (2) default in the performance of any covenant set forth in the Pledge Agreement, or repudiation by the Issuers of any of their obligations under the Pledge Agreement or the unenforceability of the Pledge Agreement against the Issuers for any reason which 43 50 in any one case or in the aggregate results in a material impairment of the rights intended to be afforded thereby; (3) default when due in the payment of principal of, or premium, if any, on any Note; (4) failure by the Issuers or any of their Restricted Subsidiaries for 30 days after written notice to them by the Trustee or by the Holders of at least 25% in aggregate principal amount of the outstanding Notes to comply with the provisions of Section 4.03, 4.04, 4.07 or 4.14 hereof; (5) failure by the Issuers or any of their Restricted Subsidiaries to perform or comply with the provisions of Section 5.01 hereof or of the Indenture; (6) failure by the Issuers or any of their Restricted Subsidiaries for 60 days after written notice to them by the Trustee or by the Holders of at least 25% in aggregate principal amount of the outstanding Notes to comply with any other covenant set forth in the Notes, Indenture or this First Supplemental Indenture; (7) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Issuers or any of their Significant Subsidiaries (or group of Restricted Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary), or the payment of which is guaranteed by the Issuers or any of their Significant Subsidiaries (or group of Restricted Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary), whether that Indebtedness or guarantee now exists or is created after the date hereof, which default (a) is caused by a failure to pay principal of or premium, if any, or interest on that Indebtedness prior to the expiration of the grace period provided in that Indebtedness on the date of such default (a "Payment Default") or (b) results in the acceleration of that Indebtedness prior to its express maturity, and, in each case, if the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more; (8) failure by the Issuers or any of their Significant Subsidiaries (or group of Restricted Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $10.0 million, excluding amounts covered by insurance, which judgments are not paid, discharged or stayed for a period of 60 days after the date on which the right to appeal has expired. (9) an Issuer or any Significant Subsidiaries of an Issuer (or group of Restricted Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary): (a) commences a voluntary case under any Bankruptcy Law; 44 51 (b) consents to the entry of an order for relief against it in an involuntary case under any Bankruptcy Law now or hereafter in effect; (c) consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of an Issuer or any Significant Subsidiary of an Issuer (or group of Restricted Subsidiaries that if treated as a single Subsidiary would constitute a Significant Subsidiary) or for all or substantially all of the property and assets of an Issuer or any of its Significant Subsidiaries (or group of Restricted Subsidiaries that if treated as a single Subsidiary would constitute a Significant Subsidiary); or (d) effects a general assignment for the benefit of its creditors; or (10) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law for: (a) relief in respect of an Issuer or any Significant Subsidiary of an Issuer (or group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary) in an involuntary case under any Bankruptcy Law now or hereafter in effect; (b) appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of an Issuer or any Significant Subsidiary of an Issuer (or group of Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary) or for all or substantially all of the property and assets of an Issuer or any Significant Subsidiary (or group of Restricted Subsidiaries that if treated as a single subsidiary would constitute a Significant Subsidiary); or (c) the winding up or liquidation of the affairs of an Issuer or any Significant Subsidiary (or group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary); and, in each case, the order or decree remains unstayed and in effect for a period of 60 consecutive days. SECTION 6.02. ACCELERATION. If an Event of Default, other than an Event of Default specified in clause (9) or (10) above, occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Issuers, and to the Trustee if such notice is given by the Holders, may, and the Trustee at the request of such Holders shall, declare, the principal of, premium, if any, and accrued but unpaid interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal, premium, if any, and accrued and unpaid interest will be immediately due and payable. In the event of a declaration of acceleration because an Event of Default set forth in clause 45 52 (7) above has occurred and is continuing, such declaration of acceleration will be automatically rescinded and annulled if the Indebtedness that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Issuers and countersigned by the holders of such Indebtedness or a trustee, fiduciary or agent for such holders, within 60 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 60-day period which has not been cured or waived during such period. If an Event of Default specified in clause (9) or (10) above occurs, the principal of, premium, if any, and accrued and unpaid interest on the Notes then outstanding will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of at least a majority in principal amount of the outstanding Notes as to which the acceleration has occurred, by written notice to the Issuers and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if, among other things, (1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and accrued and unpaid interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (2) the rescission, in the opinion of counsel, would not conflict with any judgment or decree of a court of competent jurisdiction. Notwithstanding the foregoing, the Trustee shall have no obligation to accelerate the Notes if in the best judgment of the Trustee acceleration is not in the best interest of the Holders. ARTICLE 7 INTEREST RESERVE SECTION 7.01. INTEREST RESERVE; SECURITY. The due and punctual payment of the principal of, premium, if any, and interest on the Notes when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on the Notes and performance of all other obligations of the Issuers and any Guarantors to the Holders of Notes or the Trustee under the Indenture, this First Supplemental Indenture, the Notes and the Note Guarantees, according to the terms hereunder or thereunder, shall be secured by the Pledged Securities, as provided in the Pledge Agreement which the Issuers and the Guarantor have entered into simultaneously with the execution of this First Supplemental Indenture for the benefit of the Holders of Notes. Each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of the Pledge Agreement as the same may be in effect or may be amended from time to time in accordance with its terms and authorizes and directs the Trustee to enter into the Pledge Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith. The Issuers and the Guarantor 46 53 shall deliver to the Trustee copies of all documents executed pursuant to the Indenture, this First Supplemental Indenture and the Pledge Agreement and shall do or cause to be done all such acts and things as may be necessary or proper, or as may be required by the provisions of the Pledge Agreement to assure and confirm to the Trustee the security interest in the Pledged Securities contemplated hereby, by the Pledge Agreement, or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this First Supplemental Indenture and of the Notes and the Note Guarantees secured hereby, according to the intent and purposes herein and therein expressed. The Issuers shall take, or shall cause their Restricted Subsidiaries to take, upon request of the Trustee, any and all actions reasonably required to cause the Pledge Agreement to create and maintain, as security for the obligations of the Issuers hereunder, a valid and enforceable perfected Lien on the Pledged Securities, subject to Liens permitted by the Pledge Agreement.

(a) Subject to subsections (b), (c) and (d) of this Section 7.03, Pledged Securities may be released from the Lien and security interest created by the Indenture, this First Supplemental Indenture and the Pledge Agreement at any time or from time to time upon the request of the Issuers pursuant to an Officers' Certificate certifying that all terms for release and conditions precedent hereunder and under the Pledge Agreement have been met and specifying (i) the identity of the Pledged Securities to be released and (ii) the provision of this First Supplemental Indenture which authorizes such release. The Trustee shall release (at the sole cost and expense of the Issuers) (i) all Pledged Securities (except as provided in Article 8 of the Indenture and, in particular, the funds in the trust fund described in Section 8.04 thereof) upon discharge or defeasance of this First Supplemental Indenture in accordance with Article 8 thereof; (ii) all Pledged Securities upon the payment in full of all obligations of the Issuers with respect to the Notes; and (iii) Pledged Securities that are expressly required to be released by the Pledge agreement.

(d) The release of any Pledged Securities from the terms of the Indenture, this First Supplemental Indenture and the Pledge Agreement shall not be 48 55 deemed to impair the security under this First Supplemental Indenture in contravention of the provisions hereof if and to the extent the Pledged Securities are released pursuant to the terms hereof. To the extent applicable, the Issuers shall cause TIA Section 313(b), relating to reports, and TIA Section 314(d), relating to the release of property or securities from the Lien and security interest of the Pledge Agreement and relating to the substitution therefor of any property or securities to be subjected to the Lien and security interest of the Pledge Agreement to be satisfied.

SECTION 7.04. CERTIFICATES OF THE ISSUERS. The Issuers shall furnish to the Trustee, prior to each proposed release of Pledged Securities pursuant to the Pledge Agreement (i) all documents required by TIA Section 314(d) and (ii) an Opinion of Counsel in the United States, which may be rendered by internal counsel to the Company, to the effect that, subject to customary assumptions and exclusions, such accompanying documents constitute all documents required by TIA Section 314(d). The Trustee may, to the extent permitted by Sections 7.01 and 7.02 of the Indenture, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained in such documents and such Opinion of Counsel. SECTION 7.05. AUTHORIZATION OF ACTIONS TO BE TAKEN BY THE TRUSTEE UNDER THE PLEDGE AGREEMENT. Subject to the provisions of Section 7.01 and 7.02 of the Indenture, the Trustee may, in its sole discretion and without the consent of the Holders of Notes, on behalf of the Holders of Notes, take all actions it deems necessary or appropriate in order to (a) enforce any of the terms of the Pledge Agreement and (b) collect and receive any and all amounts payable in respect of the Obligations of the Issuers hereunder, including but not limited to the appointment and approval of collateral agents and the appointment and approval of an insurance trustee. The Trustee shall have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Pledged Securities by any acts that may be unlawful or in violation of the Pledge Agreement or this Indenture, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests of the Holders of Notes in the Pledged Securities (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes or of the Trustee). SECTION 7.06. TRUSTEE'S DUTIES. The powers and duties conferred upon the Trustee by this Article 7 are solely to protect the Pledged Securities and shall not impose any duty upon the Trustee to exercise any such powers and duties, except as expressly provided in this First Supplemental Indenture. The Trustee shall be under no duty to either Issuer or any Guarantor whatsoever to make or give any presentment, 49 56 demand for performance, notice or nonperformance, protest, notice of protest, notice of dishonor, or other notice or demand in connection with any Pledged Securities, or to take any steps necessary to preserve this First Supplemental Indenture. The Trustee shall not be liable to either Issuer or any Guarantor for failure to collect or realize upon any or all of the Pledged Securities, or for any delay in doing so, nor shall the Trustee be under any duty to either Issuer or any Guarantor to take any action whatsoever with regard thereto. The Trustee shall have no duty to either Issuer, the Guarantor or any Holder to comply with any recording, filing or other legal requirements necessary to establish or maintain the validity, priority or enforceability of the Liens in, or the Trustee's rights in or to, any of the Pledged Securities. SECTION 7.07. AUTHORIZATION OF RECEIPT OF FUNDS BY THE TRUSTEE UNDER THE PLEDGE AGREEMENT. Upon an Event of Default and so long as such Event of Default continues, the Trustee may exercise in respect of the Pledged Securities, in addition to the other rights and remedies provided for herein, in the Pledge Agreement or otherwise available to it, all of the rights and remedies of a secured party under the Uniform Commercial Code or other applicable law, and the Trustee may also upon obtaining possession of the Pledged Securities as set forth herein, without notice to the Issuers, except as specified below, sell the Pledged Securities or any part thereof in one or more parcels at public or private sale, at any exchange, broker's board or at any of the Trustee's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable. The Issuers acknowledge and agree that any such private sale may result in prices and other terms less favorable to the seller than if such a sale were a public sale. The Issuers agree that, to the extent notice of sale shall be required by law, at least 10 days' notice to the Issuers of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Trustee shall not be obligated to make any sale regardless of notice of sale having been given. The Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Any cash that is Pledged Securities held by the Trustee and all cash proceeds received by the Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Pledged Securities shall be applied (unless otherwise provided for in the Pledge Agreement and after payment of any and all amounts payable to the Trustee pursuant to this Indenture), as the Trustee shall determine or as the Holders of the Notes shall direct pursuant to Section 6.05 of the Indenture, (i) against the obligations for the ratable benefit of the Holders of the Notes, (ii) to maintain, repair or otherwise protect the Pledged Securities or (iii) to take such other action to protect the other rights of the Holders of the Notes or to take any other appropriate action or remedy for the benefit of the Holders of the Notes. Any surplus of such cash or cash proceeds held by the Trustee and remaining after payment in full of all the obligations shall be paid over to the Issuers or to whomsoever may be lawfully entitled to receive such surplus or as a court of competent jurisdiction may direct. 50 57 SECTION 7.08. TERMINATION OF SECURITY INTEREST. Upon the payment in full of all interest payable on the first four scheduled interest payment dates, the Trustee shall (at the request of the Issuers accompanied by (i) an Officers' Certificate of each of the Issuers to the Trustee stating that such interest payments have been paid in full, and (ii) instructions from the Issuers to the Trustee to release the Liens pursuant to this First Supplemental Indenture and the Pledge Agreement) release the Liens securing the Pledged Securities. SECTION 7.09. COOPERATION OF TRUSTEE. In the event the Issuers or any Guarantor pledge or grant a security interest in additional Pledged Securities, the Trustee shall cooperate with the Issuers or such Guarantor in reasonably and promptly agreeing to the form of, and executing as required, any instruments or documents necessary to make effective the security interest in the Pledged Securities to be so substituted or pledged. To the extent practicable, the terms of any security agreement or other instrument or document necessitated by any such substitution or pledge shall be comparable to the provisions of the existing Pledge Agreement. Subject to, and in accordance with the requirements of this Article 7 and the terms of the Pledge Agreement, in the event that the Issuers or any Guarantor engages in any transaction pursuant to Section 7.03, the Trustee shall cooperate with the Issuers or such Guarantor in order to facilitate such transaction in accordance with any reasonable time schedule proposed by the Issuers, including by delivering and releasing the Pledged Securities in a prompt and reasonable manner. SECTION 7.10. COLLATERAL AGENT. The Trustee may, from time to time, appoint one or more Collateral Agents hereunder. Each of such Collateral Agents may be delegated any one or more of the duties or rights of the Trustee hereunder or under the Pledge Agreement or one or more Credit Facilities or which are specified in the Pledge Agreement or such Credit Facilities, including without limitation, the right to hold any Pledged Securities in the name of, registered to, or in the physical possession of, such Collateral Agent, for the rateable benefit of the Holders of the Notes. Each such Collateral Agent shall have such rights and duties as may be specified in an agreement between the Trustee and such Collateral Agent. The Trustee and any Collateral Agent shall be authorized hereunder to give any acknowledgment reasonably requested by any party under one or more Credit Facilities to confirm the rights and obligations of the parties under such Credit Facilities. ARTICLE 8 NOTE GUARANTEES SECTION 8.01. SUBSIDIARY GUARANTEES. Subject to this Article 8, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, this First Supplemental Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that: (a) the principal of premium, if any, and interest on the Notes will be 51 58 promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration pursuant to Section 6.02 hereof or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. Each Guarantor hereby agrees that its obligations with regard to this Note Guarantee shall be joint and several, unconditional, irrespective of the validity or enforceability of the Notes or the obligations of the Issuers under the Indenture, this First Supplemental Indenture, the absence of any action to enforce the same, the recovery of any judgment against the Issuers or any other obligor with respect to the Indenture, this First Supplemental Indenture, the Notes or the obligations of the Issuers under the Indenture, this First Supplemental Indenture or the Notes, any action to enforce the same or any other circumstances (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to: (a) any right to require any of the Trustee, the Holders or the Issuers (each a "Benefited Party"), as a condition of payment or performance by such Guarantor, to (1) proceed against the Issuers, any other guarantor (including any other Guarantor) of the obligations under the Note Guarantees or any other Person, (2) proceed against or exhaust any security held from the Issuers, any such other guarantor or any other Person, (3) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Issuers or any other Person, or (4) pursue any other remedy in the power of any Benefited Party whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Issuers including any defense based on or arising out of the lack of validity or the unenforceability of the obligations under the Note Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Issuers from any cause other than payment in full of the obligations under the Note Guarantees; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon any Benefited Party's errors or omissions in the administration of the obligations under the Note Guarantees, except behavior which amounts to bad faith; (e)(1) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of the Note Guarantees and any legal or equitable discharge of such Guarantor's obligations hereunder, (2) the benefit of any statute of limitations 52 59 affecting such Guarantor's liability hereunder or the enforcement hereof, (3) any rights to set-offs, recoupments and counterclaims and (4) promptness, diligence and any requirement that any Benefited Party protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of the Note Guarantees, notices of default under the Notes or any agreement or instrument related thereto, notices of any renewal, extension or modification of the obligations under the Note Guarantees or any agreement related thereto, and notices of any extension of credit to the Issuers and any right to consent to any thereof; (g) to the extent permitted under applicable law, the benefits of any "One Action" rule and (h) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Note Guarantees. Except as set forth in Section 8.6, each Guarantor hereby covenants that its Note Guarantee will not be discharged except by complete performance of the obligations contained in its Note Guarantee, the Indenture and this First Supplemental Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.02 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (y) in the event of any declaration of acceleration of such obligations as provided in Section 6.02 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. SECTION 8.02. ADDITIONAL GUARANTEES. If any Restricted Subsidiary becomes obligated pursuant to Section 4.10 hereof, then the Issuers shall cause any such Restricted Subsidiary to, within five Business Days of the date on which any such Restricted Subsidiary became so obligated, (a) execute and deliver to the Trustee a Supplemental Indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee, on a senior unsecured basis, all of the Issuers' obligations under the Notes, the Indenture and this First Supplemental Indenture on the terms set forth herein and therein and (b) deliver to the Trustee an Opinion of Counsel that, subject to customary assumptions and exclusions, such 53 60 supplemental indenture has been duly executed and delivered by such Restricted Subsidiary. Any Restricted Subsidiary that becomes a Guarantor shall remain a Guarantor unless (i) designated an Unrestricted Subsidiary by the Issuers in accordance with this First Supplemental Indenture; (ii) is otherwise released from its obligations as a Guarantor pursuant to Section 8.06 hereof; or (iii) the circumstances giving rise to the obligation to provide a guarantee under Section 4.10 no longer exist. SECTION 8.03. LIMITATION ON GUARANTOR LIABILITY. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under this Article 8 shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 8, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. SECTION 8.04. EXECUTION AND DELIVERY OF NOTE GUARANTEE. To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form included in Exhibit D shall be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by its President or one of its Vice Presidents. Each Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. SECTION 8.05. MERGER AND CONSOLIDATION OF GUARANTORS. Except as otherwise provided in Section 8.06 hereof, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person whether or not affiliated with such Guarantor unless: 54 61 (a) subject to Section 8.06 hereof, the Person formed by or surviving any such consolidation or merger (if other than a Guarantor or an Issuer) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under the Notes, the Indenture, this First Supplemental Indenture, and the Note Guarantee on the terms set forth herein or therein; and (b) the Guarantor complies with the requirements of Article 5 hereof. In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuers and delivered to the Trustee. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture, this First Supplemental Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture and this First Supplemental Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into an Issuer or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to an Issuer or another Guarantor. SECTION 8.06. RELEASE. In the event of a sale or other disposition of all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all to the capital stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) a Restricted Subsidiary of the Issuers, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Note Guarantee; provided, however, that the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation Section 4.07 hereof. Upon delivery by the Issuers to the Trustee of an Officers' Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Issuers in accordance with the provisions of the Indenture and this First Supplemental Indenture, including without limitation Section 4.07 hereof, the Trustee shall execute any documents 55 62 reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee. Any Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under the Indenture and this First Supplemental Indenture as provided in this Article 8. ARTICLE 9 LEGAL DEFEASANCE AND COVENANT DEFEASANCE SECTION 9.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE. The Issuers may, at the option of their respective Boards of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 9.02 or 9.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Nine. The provisions of this Article 9 shall modify and replace in their entirety the corresponding provisions of Article 8 of the Indenture. SECTION 9.02. LEGAL DEFEASANCE AND DISCHARGE. Upon Issuers' exercise under Section 9.01 hereof of the option applicable to this Section 9.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Issuers shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 9.05 hereof and the other Sections of this First Supplemental Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this First Supplemental Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 9.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (b) the Issuers' obligations with respect to such Notes under Article 2 of the Indenture, Article 2 of this First Supplemental Indenture and Section 4.02 of the Indenture, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers' obligations in connection therewith and (d) this Article Nine.

COVENANT DEFEASANCE. Upon the Issuers' exercise under Section 9.01 hereof of the option applicable to this Section 9.03, the Issuers shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from its obligations under the covenants contained in Sections 4.01, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13 and 4.14, hereof, and the operation of Section 5.01(5) hereof, with respect to the outstanding Notes on and after the date the conditions set forth in Section 9.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed not "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 (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuers 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 Section 6.01 hereof, but, except as specified above, the remainder of this First Supplemental Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer's exercise under Section 9.01 hereof of the option applicable to this Section 9.03 hereof, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, Sections 6.01(4) through 6.01(8) hereof shall not constitute Events of Default.
