               __% Debenture to the Trustee at the principal office of the
               Trustee in lawful money of the United States of America by

               indicate or any error in such CUSIP number shall not in any

                    A.   Article II of the Indenture is hereby supplemented
               with respect to the __% Debentures by inserting, following
               the final sentence of Section 2.6, the following:

                         The __% Debentures shall be issued in registered
                    form and shall be transferable only upon the surrender
                    of a __% Debenture for registration of transfer.  When
                    a __% Debenture is presented to the Registrar or a co-
                    registrar with a request to register a transfer, the
                    Registrar shall register the transfer as requested if
                    the requirements of Section 8-401(1) of the Uniform
                    Commercial Code are met.  When __% Debentures are
                    presented to the Registrar or a co-registrar with a
                    request to exchange them for an equal principal amount
                    of __% Debentures of other denominations, the Registrar
                    shall make the exchange as requested if the same
                    requirements are met.  To permit registration of
                    transfers and exchanges, the Company shall execute and
                    the Trustee shall authenticate __% Debentures at the
                    Registrar's or co-registrar's request.

                    B.   Article II of the Indenture is hereby supplemented
               with respect to the __% Debentures by inserting, following
               the phrase "of evidence" in the first sentence of
               Section 2.9, the phrase "that the requirements of Section 8-
               405 of the Uniform Commercial Code have been met and
               evidence". 

                    C.   Article II of the Indenture is hereby supplemented
               with respect to the __% Debentures by inserting, following
               the first sentence of Section 2.11, the following:  

                         The Company may not issue new __% Debentures to
                    replace __% Debentures it has redeemed, paid or
                    delivered to the Trustee for cancellation.

                    D.   Article II of the Indenture is hereby supplemented
               with respect to the __% Debentures by inserting, following
               the final sentence of Section 2.13, the following:  

                         SECTION 2.14.  Registrar and Paying Agent. 

                         The Company shall enter into an appropriate agency
               agreement with any Registrar, Paying Agent or co-registrar
               not a party to this Indenture, which shall incorporate the
               terms of the TIA.  The agreement shall implement the provi-
               sions of this Indenture that relate to such agent.  The
               Company shall notify the Trustee of the name and address of

                                                                         27



               

               any such agent.  If the Company fails to maintain a Regis-
               trar or Paying Agent, the Trustee shall act as such and
               shall be entitled to appropriate compensation therefor
               pursuant to Section 11.2.  The Company or any of its
               domestically incorporated Wholly Owned Subsidiaries may act
               as Paying Agent, Registrar, co-registrar or transfer agent.

                         The Company initially appoints the Trustee as
               Registrar and Paying Agent in connection with the __% De-
               bentures.

                         SECTION 2.15.  Securityholder Lists.  The Trustee
               shall preserve in as current a form as is reasonably prac-
               ticable the most recent list available to it of the names
               and addresses of Securityholders.  If the Trustee is not the
               Registrar, the Company shall furnish to the Trustee, in
               writing at least five Business days before each interest
               payment date and at such other times as the Trustee may
               request in writing, a list in such form and as of such date
               as the Trustee may reasonably require of the names and
               addresses of Securityholders.

                         SECTION 2.16.  Outstanding __% Debentures.  __%
               Debentures outstanding at any time are all __% Debentures
               authenticated by the Trustee except for those canceled by
               it, those paid pursuant to Section 2.9, those delivered to
               it for cancellation and those described in this Section as
               not outstanding.  A __% Debenture does not cease to be
               outstanding because the Company or an Affiliate of the
               Company holds the __% Debenture.

                         If a __% Debenture is replaced pursuant to Sec-
               tion 2.9, it ceases to be outstanding unless the Trustee and
               the Company receive proof satisfactory to them that the
               replaced __% Debenture is held by a bona fide purchaser.

                         If the Paying Agent segregates and holds in trust,
               in accordance with this Indenture, on a redemption date or
               maturity date money sufficient to pay all principal and
               interest payable on that date with respect to the __%
               Debentures (or portions thereof) to be redeemed or maturing,
               as the case may be, then on and after that date such __%
               Debentures (or portions thereof) cease to be outstanding and
               interest on them ceases to accrue.

                         SECTION 2.17.  Temporary __% Debentures.  Until
               definitive __% Debentures are ready for delivery, the
               Company may prepare and the Trustee shall authenticate

                                                                         28



               

               temporary __% Debentures.  Temporary __% Debentures shall be
               substantially in the form of definitive __% Debentures but
               may have variations that the Company considers appropriate
               for temporary __% Debentures.  Without unreasonable delay,
               the Company shall prepare and the Trustee shall authenticate
               definitive __% Debentures and deliver them in exchange for
               temporary __% Debentures. 

                         SECTION 2.18.  Record Date.  The Company may set a
               record date for purposes of determining the identity of
               Securityholders entitled to vote or to consent to any action
               by vote of consent authorized or permitted by Sections 3.15,
               7.5 and 7.6.  Unless this Indenture provides otherwise, such
               record date shall be the later of 30 days prior to the first
               solicitation of such consent or the date of the most recent
               list of Holders furnished to the Trustee pursuant to
               Section 2.15 prior to such solicitation.

               4.   Provisions Supplemental to Article III of the
                    Indenture.


                    A.   For purposes of the __% Debentures only,

               entirety and replaced by the following:

                         SECTION 3.12.  Governing Law.  The Indenture and
               each __% Debenture issued hereunder shall be governed by,
               and construed in accordance with, the laws of the State of
               New York but without giving effect to applicable conflicts
               of law to the extent that the application of the laws of
               another jurisdiction would be required thereby.  

                    B.   Article III of the Indenture is hereby
               supplemented with respect to the __% Debentures by
               inserting, following the final sentence of Section 3.13, the
               following:

                         SECTION 3.14.  Communication by Holders with Other
               Holders.  Securityholders may communicate pursuant to TIA
               s. 312(b) with other Securityholders with respect to their
               rights under this Indenture or the __% Debentures.  The
               Company, the Trustee, the Registrar and anyone else shall
               have the protection of TIA s. 312(c).

                         SECTION 3.15.  Rules by Trustee, Paying Agent and
               Registrar.  The Trustee may make reasonable rules for action

               by or a meeting of Securityholders.  The Registrar and the
               Paying Agent may make reasonable rules for their functions. 

               5.   Provisions Supplemental to Article IV of the Indenture.

                    A.   For purposes of the __% Debentures, Section 4.4 of
               the Indenture is hereby superseded in its entirety and shall
               not apply to the __% Debentures.

                    B.   Article IV of the Indenture is hereby supplemented

               be continuing following such Incurrence and either (i) after
               giving effect to the Incurrence of such Indebtedness and the

               may (i) pay dividends on its Capital Stock within 60 days of
               the declaration thereof if, on the declaration date, such
               dividends could have been paid in compliance with the
               Indenture, (ii) redeem, repurchase, defease, acquire or
               retire for value, any Indebtedness subordinate (whether
               pursuant to its terms or by operation of law) in right of
               payment to the __% Debentures with the proceeds of any
               Permitted Refinancing Indebtedness, (iii) acquire, redeem or
               retire Capital Stock of the Company or Indebtedness
               subordinate (whether pursuant to its terms or by operation
               of law) in right of payment to the __% Debentures in
               exchange for, or in connection with a substantially
               concurrent issuance of, Capital Stock of the Company (other
               than Redeemable Stock and other than Capital Stock issued or
               sold to a Subsidiary or an employee stock ownership plan or
               other trust established by the Company or any Subsidiary),
               (iv) consummate an exchange of Investments in Persons, the
               primary businesses of which are Related Businesses, but only

               Communications, Inc. pursuant to the Geotek Management

               (other than Investments in the Capital Stock of the Company)
               in an amount at any time outstanding not to exceed in the
               aggregate for all such Investments made in reliance upon
               this clause (vi), the sum of (1) $50 million and (2) an
               amount equal to the net reduction in Investments made by the
               Company and its Restricted Subsidiaries subsequent to the
               Issue Date in any Person resulting from payments of
               dividends, repayment of loans or advances, or other
               transfers or distributions of Property to the Company or any
               Restricted Subsidiary from any Person (but only to the
               extent such net reduction in Investments has not been

               utilized to permit a Restricted Payment pursuant to clause
               (iii)(1) or (iii)(4) in Section 4.10(a)) not to exceed, in
               the case of clause (vi)(2), the amount of such Investments
               previously made by the Company and its Restricted
               Subsidiaries in such Person which were treated as Restricted
               Payments; provided, however, that no more than $25 million
               of the aggregate Investments permitted to be made pursuant
               to this clause (vi) may be utilized to make Investments in
               Inter-Act Systems, Inc.

                         (c)  Any payments made pursuant to clauses (ii),
               (iii), (iv) and (v) of Section 4.10(b) shall be excluded
               from the calculation of the aggregate amount of Restricted
               Payments made after the Issue Date; provided, however, that
               the proceeds from the issuance of Capital Stock pursuant to
               clause (iii) of Section 4.10(b) shall not constitute Capital
               Stock Sale Proceeds for purposes of clause (iii)(2) of
               Section 4.10(a).

                         SECTION 4.11.  Limitation on Liens.  The Company
               shall not, and shall not permit any Restricted Subsidiary
               to, directly or indirectly, Incur or suffer to exist, any
               Lien (other than Permitted Liens) upon any of its Property,
               whether now owned or hereafter acquired, including any Lien
               on any interest in, or any income or profits from, its
               Property unless (a) with respect to any Restricted
               Subsidiary, such Lien secures Indebtedness other than
               Guarantees of Indebtedness of the Company or (b) effective
               provision has been or will be made whereby the __%
               Debentures will be secured by such Lien; provided, however,
               that no Lien may be granted with respect to Indebtedness of
               the Company that is subordinated to the __% Debentures.

                         SECTION 4.12.  Limitation on Asset Sales.  (a) The
               Company shall not, and shall not permit any Restricted
               Subsidiary to, directly or indirectly, consummate any Asset
               Sale after the Issue Date unless (i) the Company or such
               Restricted Subsidiary, as the case may be, receives
               consideration at the time of such Asset Sale at least equal
               to the Fair Market Value of the Property subject to such
               Asset Sale and (ii) (A) at least 80% of the consideration
               paid to the Company or such Restricted Subsidiary in
               connection with such Asset Sale is in the form of cash or
               cash equivalents or (B) the consideration paid to the
               Company or such Restricted Subsidiary is determined in good
               faith by the Board of Directors of the Company, as evidenced
               by a Board Resolution, to be substantially comparable in
               type to the assets being sold.

                         (b)  The Net Available Cash (or any portion
               thereof) from Asset Sales may be applied by the Company or a
               Restricted Subsidiary, to the extent the Company or such
               Restricted Subsidiary elects, (i) to prepay, repay or
               purchase Indebtedness under the Credit Facility or
               Indebtedness of a Restricted Subsidiary (excluding
               Indebtedness owed to the Company or an Affiliate of the
               Company); or (ii) to reinvest in Additional Assets
               (including by means of an Investment in Additional Assets by
               a Restricted Subsidiary with Net Available Cash received by
               the Company or another Restricted Subsidiary).  Any Net
               Available Cash from an Asset Sale not applied in accordance
               with the first sentence of this Section 4.12(b) within one
               year from the date of such Asset Sale or the receipt of such
               Net Available Cash shall constitute "Excess Proceeds".  When
               the aggregate amount of Excess Proceeds exceeds $15 million
               (taking into account income earned on such Excess Proceeds),
               the Company will be required to make an offer to purchase
               (the  Prepayment Offer ) the __% Debentures, on a pro rata
               basis according to principal amount, at a purchase price
               equal to 100% of the principal amount thereof plus accrued
               and unpaid interest thereon (if any) to the date of purchase
               in accordance with the procedures (including prorating in
               the event of oversubscription) set forth in the Indenture. 
               If the aggregate principal amount of __% Debentures
               surrendered for purchase by holders thereof exceeds the
               amount of Excess Proceeds, then the Trustee shall select the
               __% Debentures to be purchased pro rata according to
               principal amount or by lot with such adjustments as may be
               deemed appropriate by the Company so that only __%
               Debentures in denominations of $1,000, or integral multiples
               thereof, shall be purchased.  To the extent that any portion
               of the amount of Net Available Cash remains after compliance
               with the preceding sentence and provided that all holders of
               __% Debentures have been given the opportunity to tender
               their __% Debentures for purchase as described in
               Section 4.12(c), the Company or such Restricted Subsidiary
               may use such remaining amount for general corporate purposes
               and the amount of Excess Proceeds will be reset to zero. 

                         (c)  Within five Business days after one year from
               the date of an Asset Sale or the receipt of Net Available
               Cash therefrom, the Company shall, if it is obligated to
               make a Prepayment Offer, send a written notice, by first-
               class mail, to the holders of the __% Debentures (the
               "Prepayment Offer Notice"), accompanied by such information
               regarding the Company and its Subsidiaries as the Company in
               good faith believes will enable such holders of the __%

               Debentures to make an informed decision with respect to the
               Prepayment Offer.  The Prepayment Offer Notice will state,
               among other things, (i) that the Company is offering to
               purchase __% Debentures pursuant to the provisions of this
               Section 4.12, (ii) that any Debenture (or any portion
               thereof) accepted for payment (and duly paid on the Purchase
               Date) pursuant to the Prepayment Offer shall cease to accrue
               interest after the Purchase Date, (iii) the purchase price
               and purchase date, which shall be, subject to any contrary
               requirements of applicable law, no less than 30 days nor
               more than 60 days from the date the Prepayment Offer Notice
               is mailed (the "Purchase Date"), (iv) the aggregate
               principal amount of __% Debentures (or portions thereof) to
               be purchased and (v) a description of the procedure which
               holders of __% Debentures must follow in order to tender
               their __% Debentures (or portions thereof) and the
               procedures that holders of __% Debentures must follow in
               order to withdraw an election to tender their __% Debentures
               (or portions thereof) for payment.

                         SECTION 4.13  Limitation on Restrictions on
               Distributions from Restricted Subsidiaries.  The Company
               shall not, and shall not permit any of its Restricted
               Subsidiaries to, directly or indirectly, create or otherwise
               cause or suffer to exist or become effective, or enter into
               any agreement with any Person that would cause to become
               effective, any consensual encumbrance or restriction on the
               ability of any Restricted Subsidiary to (a) pay dividends,
               in cash or otherwise, or make any other distributions on or
               in respect of its Capital Stock, or pay any Indebtedness or
               other obligation owed, to the Company or any other
               Restricted Subsidiary, (b) make any loans or advances to the
               Company or any other Restricted Subsidiary or (c) transfer
               any of its Property to the Company or any other Restricted
               Subsidiary. Such limitation will not apply (1) with respect
               to clauses (a), (b) and (c), to encumbrances and
               restrictions (i) in existence under or by reason of any
               agreements (not otherwise described in clause (iii)) in
               effect on the Issue Date, (ii) relating to Indebtedness of a
               Restricted Subsidiary and existing at such Restricted
               Subsidiary at the time it became a Restricted Subsidiary if
               such encumbrance or restriction was not created in
               connection with or in anticipation of the transaction or
               series of related transactions pursuant to which such
               Restricted Subsidiary became a Restricted Subsidiary or was
               acquired by the Company, (iii)(a) any encumbrance or
               restriction pursuant to the Credit Facility, provided that
               such restrictions or encumbrances are no less favorable to

               the holders of the __% Debentures than those restrictions or
               encumbrances pursuant to the Credit Facility as in effect on
               the date of the Indenture; provided further, however, that
               the provisions of the Credit Facility permit distributions
               to the Company for the purpose of, and in an amount
               sufficient to fund, the payment of principal due at maturity
               and interest in respect of the __% Debentures (provided, in
               either case, that such payment is due or to become due
               within 30 days from the date of such distribution) at a time
               when there does not exist an event which after notice or
               passage of time or both would permit the lenders under the
               Credit Facility to declare all amounts thereunder due and
               payable or (iv) which result from the renewal, refinancing,
               extension or amendment of an agreement referred to in the
               immediately preceding clauses (1)(i) and (ii) above and in
               clauses (2)(i) and (ii) below, provided, such encumbrance or
               restriction is no more restrictive to such Restricted
               Subsidiary and is not materially less favorable to the
               holders of __% Debentures than those under or pursuant to
               the agreement evidencing the Indebtedness so extended,
               renewed, refinanced or replaced, and (2) with respect to
               clause (c) only, to (i) any encumbrance or restriction
               relating to Indebtedness that is permitted to be Incurred
               and secured pursuant to the provisions under Section 4.9 and
               Section 4.11 that limits the right of the debtor to dispose
               of the assets or Property securing such debt, (ii) any
               encumbrance or restriction in connection with an acquisition
               of Property, so long as such encumbrance or restriction
               relates solely to the Property so acquired and was not
               created in connection with or in anticipation of such
               acquisition, (iii) customary provisions restricting
               subletting or assignment of leases and customary provisions
               in other agreements that restrict assignment of such
               agreements or rights thereunder or (iv) customary
               restrictions contained in asset sale agreements limiting the
               transfer of such assets pending the closing of such sale.

                         SECTION 4.14.  Limitation on Transactions with
               Affiliates.  (a)  The Company shall not, and shall not
               permit any Restricted Subsidiary to, directly or indirectly,
               conduct any business or enter into or suffer to exist any
               transaction or series of transactions (including the
               purchase, sale, transfer, lease or exchange of any Property
               or the rendering of any service) with, or for the benefit
               of, any Affiliate of the Company (an "Affiliate
               Transaction") unless (i) the terms of such Affiliate
               Transaction are (1) set forth in writing, (2) in the best
               interest of the Company or such Restricted Subsidiary, as

               the case may be, and (3) no less favorable to the Company or
               such Restricted Subsidiary, as the case may be, than those
               that could be obtained in a comparable arm's-length
               transaction with a Person that is not an Affiliate of the
               Company or such Restricted Subsidiary, (ii) with respect to
               an Affiliate Transaction involving aggregate payments or
               value in excess of $15 million, the Board of Directors of
               the Company (including a majority of the disinterested
               members of the Board of Directors of the Company) approves
               such Affiliate Transaction and, in its good faith judgment,
               believes that such Affiliate Transaction complies with
               clauses (i)(2) and (3) of this paragraph as evidenced by a
               Board Resolution and (iii) with respect to an Affiliate
               Transaction involving aggregate payments or value in excess
               of $25 million, the Company obtains a written opinion from
               an independent appraisal firm to the effect that such
               Affiliate Transaction is fair, from a financial point of
               view.

                         (b) Notwithstanding Section 4.14(a), the Company
               may enter into or suffer to exist the following: (i) any
               transaction pursuant to any contract in existence on the
               Issue Date; (ii) any transaction or series of transactions
               between the Company and one or more of its Restricted
               Subsidiaries or between two or more of its Restricted
               Subsidiaries; (iii) any Restricted Payment permitted to be
               made pursuant to Section 4.10; (iv) the payment of
               compensation (including, amounts paid pursuant to employee
               benefit plans) for the personal services of officers,
               directors and employees of the Company or any of its
               Restricted Subsidiaries, so long as the Board of Directors
               of the Company in good faith shall have approved the terms
               thereof and deemed the services theretofore or thereafter to
               be performed for such compensation or fees to be fair
               consideration therefor; and (v) loans and advances to
               employees made in the ordinary course of business and
               consistent with past practice of the Company or such
               Restricted Subsidiary, as the case may be, provided that
               such loans and advances do not exceed $15 million at any one
               time outstanding.

                         SECTION 4.15.  Ownership of Vanguard Cellular
               Financial Corp.  The Company will at all times maintain its
               direct 100% ownership of the Capital Stock of Vanguard
               Cellular Financial Corp., the primary obligor with respect

               the final sentence of Section 5.7, the following (which, to
               the extent inconsistent therewith, shall supersede Section
               5.2 of the Indenture with respect to the __% Debentures):

                         SECTION 5.8.  Notices to Trustee.  If the Company

               provided for in this Section at least 60 days before the

               7.   Provisions Supplemental to Article VI of the Indenture.

                    A.   For purposes of the __% Debentures only,
               Section 6.1 of the Indenture is hereby superseded in its
               entirety and replaced by the following:

                         SECTION 6.1.  Discharge of Liability on __%
               Debentures; Defeasance.  (a)  When (i) the Company delivers
               to the Trustee all outstanding __% Debentures (other than
               __% Debentures replaced pursuant to Section 2.9) for
               cancellation or (ii) all outstanding __% Debentures have
               become due and payable, whether at maturity or as a result
               of the mailing of a notice of redemption pursuant to
               Article V of the Indenture, and the Company irrevocably
               deposits with the Trustee funds sufficient to pay at
               maturity or upon redemption all outstanding __% Debentures,
               including interest thereon (other than __% Debentures
               replaced pursuant to Section 2.9), and if in either case the
               Company pays all other sums payable hereunder by the
               Company, then this Indenture shall, subject to Sections
               6.1(c) and 6.5, cease to be of further effect with respect
               to the __% Debentures.  The Trustee shall acknowledge
               satisfaction and discharge of this Indenture on demand of
               the Company accompanied by an Officers' Certificate and an
               Opinion of Counsel and at the cost and expense of the
               Company.

                         (b)  Subject to Sections 6.1(c), 6.1A and 6.5, the
               Company at any time may terminate (i) all its obligations
               under the __% Debentures and this Indenture with respect to
               the __% Debentures ("legal defeasance option") or (ii) its
               obligations under Sections 4.9, 4.10, 4.11, 4.12, 4.13,
               4.14, 4.15, 4.16 (to the extent that failure to comply with
               such Section 4.16 shall not violate the TIA), and
               Section 10.1(a)(iv) and the related operation of
               Section 7.1(4) and the operation of Sections 7.1(6), 7.1(7)
               (with respect to Restricted Subsidiaries), 7.1(8) (with
               respect to Restricted Subsidiaries) and 7.1(9) ("covenant
               defeasance option").  The Company may exercise its legal
               defeasance option notwithstanding its prior exercise of its
               covenant defeasance option.

                         If the Company exercises its legal defeasance
               option, payment of the __% Debentures may not be accelerated
               because of an Event of Default.  If the Company exercises
               its covenant defeasance option, payment of the __%
               Debentures may not be accelerated because of an Event of
               Default specified in Sections 7.1(4), 7.1(5) (with respect










                                                                         39



               

               to Section 10.1(a)(iv)), 7.1(6), 7.1(7) (with respect to
               Restricted Subsidiaries), 7.1(8) (with respect to Restricted
               Subsidiaries) and 7.1(9) (except to the extent covenants or
               agreements referenced in such Sections remain applicable).

                         Upon satisfaction of the conditions set forth
               herein and upon request of the Company, the Trustee shall
               acknowledge in writing the discharge of those obligations
               that the Company terminates.

                         (c)  Notwithstanding clauses (a) and (b) above,
               the Company's obligations in Sections 2.7, 2.9, 2.10, 2.14,
               2.15, 4.8, 6.2, 6.4, 6.5, 11.2 and 11.6 shall survive until
               the __% Debentures have been paid in full.  Thereafter, the
               Company's obligations in Sections 6.2, 6.4 and 11.2 shall
               survive.

                         SECTION 6.1A.  Conditions to Defeasance.  The
               Company may exercise its legal defeasance option or its
               covenant defeasance option only if:

                         (1) the Company irrevocably deposits in trust with
                    the Trustee money or U.S. Government Obligations for
                    the payment of principal and interest on the __%
                    Debentures to maturity or redemption, as the case may
                    be;

                         (2) the Company delivers to the Trustee a
                    certificate from a nationally recognized firm of

                    without reinvestment on the deposited U.S. Government
                    Obligations plus any deposited money without investment
                    will provide cash at such times and in such amounts as
                    will be sufficient to pay principal and interest when
                    due on all the __% Debentures to maturity or
                    redemption, as the case may be;

                         (3) 123 days pass after the deposit is made and
                    during the 123-day period no Default specified in
                    Section 7.1(7) or (8) with respect to the Company
                    occurs which is continuing at the end of the period;

                         (4) no Default has occurred and is continuing on
                    the date of such deposit and after giving effect

                         (5) the deposit does not constitute a default
                    under any other agreement binding on the Company;

                         (6) the Company delivers to the Trustee an Opinion
                    of Counsel to the effect that the trust resulting from
                    the deposit does not constitute, or is qualified as, a
                    regulated investment company under the Investment
                    Company Act of 1940;

                         (7) in the case of the legal defeasance option,

                    change in the applicable Federal income tax law, in
                    either case to the effect that, and based thereon such
                    Opinion of Counsel shall confirm that, the
                    Securityholders will not recognize income, gain or loss
                    for Federal income tax purposes as a result of such
                    defeasance and will be subject to Federal income tax on
                    the same amounts, in the same manner and at the same
                    times as would have been the case if such defeasance
                    had not occurred;

                         (8) in the case of the covenant defeasance option,
                    the Company shall have delivered to the Trustee an
                    Opinion of Counsel to the effect that the
                    Securityholders will not recognize income, gain or loss
                    for Federal income tax purposes as a result of such
                    covenant defeasance and will be subject to Federal
                    income tax on the same amounts, in the same manner and
                    at the same times as would have been the case if such
                    covenant defeasance had not occurred; and

                         (9) the Company delivers to the Trustee an
                    Officers' Certificate and an Opinion of Counsel, each

                    and discharge of the __% Debentures as contemplated by
                    this Article VI have been complied with.

                         Before or after a deposit, the Company may make
               arrangements satisfactory to the Trustee for the redemption
               of __% Debentures at a future date in accordance with

                         part of its property; or

                              (C) orders the winding up or liquidation of
                         the Company or any Restricted Subsidiary;

                    or any similar relief is granted under any foreign
                    laws, and any order or decree described in this Section
                    7.1(8) remains unstayed and in effect for 60 days; or

                         (9) any judgment or decree for the payment of
                    money in excess of $15,000,000 or its Dollar Equivalent
                    at the time is entered against the Company or any
                    Restricted Subsidiary and is not discharged and either
                    (A) an enforcement proceeding has been commenced by any
                    creditor upon such judgment or decree or (B) there is a
                    period of 30 consecutive days following the entry of
                    such judgment or decree during which, in the case of
                    (A) or (B), such enforcement proceeding, judgment or
                    decree is not discharged, waived or the execution
                    thereof stayed and such default continues for 10 days
                    after the notice specified below.

                         The foregoing will constitute Events of Default
               whatever the reason for any such Event of Default and
               whether it is voluntary or involuntary or is effected by
               operation of law or pursuant to any judgment, decree or
               order of any court or any order, rule or regulation of any
               administrative or governmental body.

                         The term "Bankruptcy Law" means Title 11, United
               States Code, or any similar Federal or state law for the
               relief of debtors.  The term "Custodian" means any receiver,
               trustee, assignee, liquidator, custodian or similar official
               under any Bankruptcy Law.

                         A Default under clause (4), (5), (6) or (9) is not
               an Event of Default until the Trustee or the Holders of at
               least 25% in principal amount of the __% Debentures notify
               the Company of the Default and the Company does not cure
               such Default within the time specified after receipt of such
               notice.  Such notice must specify the Default, demand that
               it be remedied and state that such notice is a "Notice of
               Default".  

                         The Company shall deliver to the Trustee, within
               30 days after the occurrence thereof, written notice in the

               form of an Officers' Certificate of any event which with the
               giving of notice and the lapse of time would become an Event
               of Default under clause (4), (5), (6) or (9), its status and
               what action the Company is taking or proposes to take with
               respect thereto.  

                    B.   For purposes of the __% Debentures only, the first
               two sentences of Section 7.2 of the Indenture are hereby
               superseded in their entirety and replaced by the following:

                         If an Event of Default (other than an Event of
               Default specified in Section 7.1(7) or (8) with respect to
               the Company) occurs and is continuing, the Trustee by notice
               to the Company, or the Holders of at least 25% in principal
               amount of the __% Debentures by notice to the Company and
               the Trustee, may declare the principal of and accrued
               interest on all the __% Debentures to be due and payable. 
               Upon such a declaration, such principal and interest shall
               be due and payable immediately.  If an Event of Default
               specified in Section 7.1(7) or (8) with respect to the
               Company occurs, the principal of and interest on all the __%
               __% Debentures shall become and be immediately due and
               payable without any declaration or other action the part of
               the Trustee or any Securityholders.  The Holders of a
               majority in principal amount of the __% Debentures by notice
               to the Trustee may rescind an acceleration and its
               consequences if the rescission would not conflict with any
               judgment or decree and if all existing Events of Default
               have been cured or waived except nonpayment of principal or
               interest that has become due solely because of acceleration. 
               No such rescission shall affect any subsequent Default or
               impair any right consequent thereto.

                    C.   Article VII of the Indenture is hereby
               supplemented with respect to the __% Debentures by
               inserting, following the final sentence of Section 7.2, the
               following:

                    The Trustee may fix a record date and payment date for
                    any payment to Securityholders pursuant to this
                    Section.  At least 15 days before such record date, the
                    Company shall mail to each Securityholder and the
                    Trustee a notice that states the record date, the
                    payment date and amount to be paid.

                    D.   Article VII of the Indenture is hereby
               supplemented with respect to the __% Debentures by

               inserting, following the final word of the first sentence of
               the second paragraph of Section 7.5, the following:

                    or a Default in respect of a provision that under
                    Section 12.2 cannot be amended without the consent of
                    each Securityholder affected

                    E.   For purposes of the __% Debentures only, the term
               "a majority" in the first sentence of Section 7.7 of the
               Indenture is hereby superseded and replaced by the phrase
               "at least 25%".

                    F.   Article VII of the Indenture is hereby
               supplemented with respect to the __% Debentures by
               inserting, following the final sentence of Section 7.9, the
               following:

                         SECTION 7.10.  Undertaking for Costs.  In any suit
               for the enforcement of any right or remedy under this
               Indenture or in any suit against the Trustee for any action
               taken or omitted by it as Trustee, a court in its discretion
               may require the filing by any party litigant in the suit of
               an undertaking to pay the costs of the suit, and the court
               in its discretion may assess reasonable costs, including
               reasonable attorneys' fees and expenses, against any party
               litigant in the suit, having due regard to the merits and
               good faith of the claims or defenses made by the party
               litigant.  This Section does not apply to a suit by the
               Trustee, a suit by a Holder pursuant to Section 7.7 or a
               suit by Holders of more than 10% in principal amount of the
               __% Debentures.  

               9.   Provisions Supplemental to Article X of the Indenture.

                    A.   For purposes of the __% Debentures only,
               Section 10.1 of the Indenture is hereby superseded in its
               entirety and replaced by the following:

                         SECTION 10.1.  When Company May Merge or Transfer
               Property.  (a) The Company shall not consolidate with or
               merge with or into any Person, or convey, transfer or lease
               all or substantially all its Property, unless:  (i) either
               (a) the Company shall be the continuing Person in the case
               of a merger or consolidation or (b) the resulting, surviving
               or transferee Person if other than the Company (the
               "Successor Company") shall be a corporation organized and
               existing under the laws of the United States of America, any
               State thereof or the District of Columbia and the Successor










                                                                         46



               

               Company shall expressly assume, by an indenture supplemental
               hereto, executed and delivered to the Trustee, in form
               satisfactory to the Trustee, all the obligations of the
               Company under the __% Debentures and this Indenture; (ii) in
               the case of a sale, transfer, assignment, lease, conveyance
               or other disposition of all or substantially all of the
               Company's Property, such Property shall have been
               transferred as an entirety or virtually as an entirety to
               the Successor Company; (iii) immediately before and after
               giving effect to such transaction on a pro forma basis (and
               treating any Indebtedness which becomes an obligation of the
               Successor Company or any Restricted Subsidiary as a result
               of such transaction as having been Incurred by the Successor
               Company or such Restricted Subsidiary at the time of such
               transaction), no Default or Event of Default shall have
               occurred and be continuing; (iv) immediately after giving

               the Company, the Successor Company or such Restricted
               Subsidiary at the time of such transaction), the Company or

               additional $1.00 of Indebtedness pursuant to clause (i) of 
               Section 4.9(a); and (v) the Company shall have delivered to
               the Trustee an Officers' Certificate and an Opinion of
               Counsel, each stating that such consolidation, merger or
               transfer and such supplemental indenture (if any) comply
               with this Indenture.

                         (b) The Successor Company shall succeed to, and be
               substituted for, and may exercise every right and power of,
               the Company under this Indenture, but the predecessor
               Company in the case of a lease shall not be released from
               the obligation to pay the principal of and interest on the
               __% Debentures.

               of Section 10.1(a), any Restricted Subsidiary may

                    participation in other securities of the Company are
                    outstanding if the requirements for such exclusion set
                    forth in TIA s. 310(b)(1) are met.

                    C.   Article XI of the Indenture is hereby supplemented

                    After an amendment under this Section becomes
                    effective, the Company shall mail to Securityholders a
                    notice briefly describing such amendment.  The failure
                    to give such notice to all Securityholders, or any
                    defect therein, shall not impair or affect the validity

               of at least a majority in principal amount of the __%

                    payment of interest on any __% Debenture;

                         (3) reduce the principal of or extend the Stated

                    subordinate, the __% Debentures to any other obligation
                    of the Company; or

                         (7) make any change in Section 7.5, 7.6 or 7.7 or
                    the second sentence of this Section.

                         It shall not be necessary for the consent of the
               Holders under this Section to approve the particular form of
               any proposed amendment, but it shall be sufficient if such
               consent approves the substance thereof.

               subsequent Holder of that __% Debenture or portion of the
               __% Debenture that evidences the same debt as the consenting
               Holder's __% Debenture, even if notation of the consent or
               waiver is not made on the __% Debenture.  However, any such
               Holder or subsequent Holder may revoke the consent or waiver
               as to such Holder's __% Debenture or portion of the __%
               Debenture if the Trustee receives the notice of revocation
               before the date the amendment or waiver becomes effective. 
               After an amendment or waiver becomes effective, it shall
               bind every Securityholder.

                         The Company may, but shall not be obligated to,
               fix a record date for the purpose of determining the
               Securityholders entitled to give their consent or take any
               other action described above or required or permitted to be
               taken pursuant to this Indenture.  If a record date is
               fixed, then notwithstanding the immediately preceding
               paragraph, those Persons, who were Securityholders at such
               record date (or their duly designated proxies), and only
               those Persons, shall be entitled to give such consent or to
               revoke any consent previously given or to take any such
               action, whether or not such Persons continue to be Holders
               after such record date.  No such consent shall be valid or
               effective for more than 120 days after such record date.

                         SECTION 12.7.  Trustee To Sign Amendments.  The
               Trustee shall sign any amendment authorized pursuant to this
               Article XII if the amendment does not adversely affect the
               rights, duties, liabilities or immunities of the Trustee. 
               If it does, the Trustee may but need not sign it.  In
               signing such amendment the Trustee shall be entitled to
               receive indemnity reasonably satisfactory to it and to

               receive, and (subject to Section 11.1) shall be fully
               protected in relying upon, an Officers' Certificate and an
               Opinion of Counsel stating that such (i) amendment is
               authorized or permitted by this Indenture and that all
               conditions precedent to execution, delivery and performance
               of such amendment have been satisfied; (ii) the Company has
               all necessary corporate power and authority to execute and
               deliver the amendment and that the execution, delivery and
               performance of such amendment has been duly authorized by
               all necessary corporate action; (iii) the execution,
               delivery and performance of the amendment do not conflict
               with, or result in the breach of or constitute a default
               under any of the terms, conditions or provisions of (a) the
               Indenture, (b) the Articles of Incorporation or ByLaws of
               the Company, (c) any law or regulation applicable to the
               Company, (d) any material order, writ, injunction or decree
               of any court or governmental instrumentality applicable to
               the Company or (e) any material agreement or instruments to

               duly and validly executed and delivered by the Company, and
               the Indenture together with such amendment constitutes a
               legal, valid and binding obligation of the Company
               enforceable against the Company in accordance with its
               terms, except as such enforceability may be limited by
               applicable bankruptcy, insolvency or similar laws affecting
               the enforcement of creditors' rights generally and general
               equitable principles; and (v) the Indenture together with
               such amendment complies with the TIA.  Any opinion of
               counsel with respect to the foregoing may be based upon such
               counsel's knowledge of the Company and may contain such
               other qualifications as shall be reasonably acceptable to
               the Trustee.

                         SECTION 12.8.  Payment for Consent.  Neither the
               Company nor any Affiliate of the Company shall, directly or
               indirectly, pay or cause to be paid any consideration,
               whether by way of interest, fee or otherwise, to any Holder
               for or as an inducement to any consent, waiver or amendment
               of any of the terms or provisions of this Indenture or the
               __% Debentures unless such consideration is offered to be
               paid to all Holders that so consent, waive or agree to amend
               in the time frame set forth in solicitation documents
               relating to such consent, waiver or agreement.

                    D.   The Indenture is hereby supplemented with respect
               to the __% Debentures by inserting, following the final
               sentence of Section 13.12, the following:

                                Right to Require Repurchase


                         SECTION 14.1.  Purchase of the Option of Holders
               Upon a Change of Control.  (a)  Upon a Change of Control
               Triggering Event, each Holder shall have the right to
               require that the Company repurchase such Holder's __%
               Debentures at a purchase price in cash equal to 101% of the
               principal amount thereof plus accrued and unpaid interest,
               if any, to the date of purchase (subject to the right of
               holders of record on the relevant record date to receive
               interest due on the related interest payment date), in
               accordance with the terms contemplated in Section 14.1(b).  

                         (b)  Within 30 days following any Change of
               Control Triggering Event, the Company shall cause a notice
               of the offer required by this Section 14.1 to be sent at
               least once to the Dow Jones News Service or similar business
               news service in the United States and send, by first-class

                         (1) that a Change of Control Triggering Event has
                    occurred and that such Holder has the right to require
                    the Company to purchase such Holder's __% Debentures at
                    a purchase price in cash equal to 101% of the principal
                    amount thereof plus accrued and unpaid interest, if
                    any, to the date of purchase;

                         (2) the circumstances and relevant facts regarding
                    such Change of Control Triggering Event which the
                    Company in good faith believes will enable Holders to
                    make an informed decision (which at a minimum will
                    include (i) the most recently filed Annual Report on
                    Form 10-K (including audited financial statements) of
                    the Company, the most recent subsequently filed
                    Quarterly Report on Form 10-Q and any Current Report on
                    Form 8-K of the Company filed subsequent to such
                    Quarterly Report, (ii) a description of material

                    historical income, cash flow and capitalization, each
                    after giving effect to the Change of Control;

                         (4) the date such Change of Control Triggering
                    Event is deemed to have occurred;

                         (3) the purchase date (which shall be no earlier
                    than 30 days nor later than 60 days from the date such
                    notice is mailed); and

                         (4) the instructions determined by the Company,
                    consistent with this Section, that a Holder must follow
                    in order to have its __% Debentures purchased, together
                    with the information contained in Section 14.1(c) (and
                    including any related materials).

                         (c)  Not later than the date upon which written
               notice required by Section 14.1(b) is delivered to the
               Trustee, the Company shall irrevocably deposit with the
               Trustee or with a paying agent (or, if the Company is acting
               as its own paying agent, segregate and hold in trust) in
               Temporary Cash Investments an amount equal to the purchase
               price plus accrued and unpaid interest, if any, to the
               Holders entitled thereto, to be held for payment in
               accordance with the provisions of this Section.  Holders
               electing to have a __% Debenture purchased will be required
               to surrender the __% Debenture, with an appropriate form
               duly completed, to the Company at the address specified in
               the notice at least five Business days prior to the purchase
               date.  Holders will be entitled to withdraw their election
               if the Trustee or the Company receives not later than three
               Business days prior to the purchase date, a facsimile
               transmission or letter setting forth the name of the Holder,
               the principal amount of the __% Debenture which was
               delivered for purchase by the Holder, the certificate number
               of such __% Debenture and a statement that such Holder is
               withdrawing his election to have such __% Debenture
               purchased.

                         (d)  On the purchase date, the Company shall
               deliver to the Trustee the __% Debentures or portions
               thereof which have been properly tendered to and are to be
               accepted by the Company.  The Trustee shall, on the purchase
               date, mail or deliver payment of the purchase price to each
               tendering Holder.  In the event that the aggregate purchase
               price of the __% Debentures delivered by the Company to the
               Trustee is less than the amount deposited with the Trustee,

               the Trustee shall deliver the excess to the Company
               immediately after the end of the payment date.

                         SECTION 14.2.  Covenant to Comply with Securities
               Laws upon Purchase of __% Debentures.  In connection with
               any purchase of securities under Section 4.12 or
               Section 14.1 by the Company, the Company shall, to the
               extent then applicable and required by law, (i) comply with
               Rule 14e-1 (which term, as used herein, includes any
               successor provisions thereto) under the Exchange Act and
               (ii) otherwise comply with all Federal and state securities
               laws so as to permit the rights and obligations under
               Section 4.12 or Section 14.1 to be exercised in the time and
               in the manner specified in such Sections.  To the extent
               that the provisions of any such securities laws or
               regulations conflict with the provisions of Section 4.12 or
               Section 14.1, the Company shall comply with the applicable
               securities laws and regulations and shall not be deemed to
               have breached its obligations described in such Section 4.12
               or Section 14.1 by virtue thereof.

               WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING
               EFFECT TO APPLICABLE CONFLICTS OF LAW TO THE EXTENT THAT THE
               APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
               REQUIRED THEREBY.

1.  Interest

                  Vanguard Cellular Systems,  Inc., a North Carolina corporation

hereinafter  referred to, being herein  called the  "Company"),  promises to pay
interest on the  principal  amount of this  Security at the rate per annum shown
above. The Company will pay interest  semiannually on and of each year. Interest
on the  Securities  will accrue from the most recent date to which  interest has
been paid or, if no interest has been paid,  from . Interest will be computed on
the basis of a 360-day  year of twelve  30-day  months.  The  Company  shall pay

the close of business on the or next preceding the interest payment date even if
Securities  are  canceled  after the record  date and on or before the  interest
payment  date.  Holders must  surrender  Securities to a Paying Agent to collect
principal payments.  The Company will pay principal and interest in money of the

Indenture  and  those  made  part of the  Indenture  by  reference  to the Trust
Indenture Act of 1939 (15 U.S.C.  ss.ss.  77aaa-77bbbb) as in effect on the date

Company limited to $200,000,000  aggregate  principal amount (subject to Section

distributions,  incur Indebtedness,  enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted  Subsidiaries,
enter into or permit certain transactions with Affiliates, create or incur Liens
and make Asset Sales.  The Indenture also imposes  limitations on the ability of
the Company to  consolidate or merge with or into any other Person or permit any
other  Person  to merge  with or into the  Company,  or  sell,  convey,  assign,
transfer, lease or otherwise dispose of all or substantially all of the Property

                  2002                                                    %

before  a  Redemption  Date,  the  Company  will  send a notice  of  redemption,
first-class  mail,  postage prepaid,  to Holders of Securities to be redeemed at
the addresses of such Holders as they appear in the Security Register.

                  If less than all of the  Securities  are to be redeemed at any
time,  the Securities to be redeemed will be chosen by the Trustee in accordance
with the Indenture. If any Security is redeemed subsequent to a Record Date with
respect to any  Interest  Payment Date  specified  above and on or prior to such
Interest  Payment Date, then any accrued  interest will be paid on such Interest
Payment  Date to the Holder of the  Security  at the close of  business  on such
Record Date. If money in an amount sufficient to pay the Redemption Price of all
Securities  (or  portions  thereof)  to be redeemed  on the  Redemption  Date is

redeemed on the applicable Redemption Date will cease to accrue.

                  The Securities are not subject to any sinking fund.

7.     Repurchase of Securities at the Option of Holders upon
       Change of Control

                  Upon the  occurrence of a Change of Control  Triggering  Event
with respect to the Securities,  each Holder of Securities  shall have the right
to require the Company to purchase such  Holder's  Securities,  in whole,  or in
part in a principal amount that is an integral multiple of $1,000, pursuant to a
Change  of  Control  Offer,  at a  purchase  price in cash  equal to 101% of the
principal  amount thereof on any Change of Control Payment Date plus accrued and
unpaid interest, if any, to the Change of Control Payment Date.

                  Within 30  calendar  days  following  any  Change  of  Control
Triggering  Event,  the Company shall send, or cause to be sent, by  first-class
mail,  postage  prepaid,  a notice  regarding the Change of Control Offer to the
Trustee and each Holder of Securities.  The Holder of this Security may elect to
have this Security or a portion hereof in an authorized  denomination  purchased
by completing the form entitled  "Option of Holder to Elect Purchase"  appearing
below and  tendering  this  Security  pursuant  to the Change of Control  Offer.
Unless the Company  defaults  in the  payment of the Change of Control  Purchase
Price with respect  thereto,  all  Securities or portions  thereof  accepted for
payment  pursuant to the Change of Control  Offer will cease to accrue  interest
from and after the Change of Control Payment Date.


8.     Repurchase of Securities at the Option of Holders upon
       Asset Sale

                  If at  any  time  the  Company  or any  Restricted  Subsidiary
engages in any Asset Sale, as a result of which the  aggregate  amount of Excess
Proceeds exceeds  $15,000,000,  the Company shall,  within five Business days of
the  date  the  amount  of  Excess  Proceeds   exceeds   $15,000,000,   use  the

Proceeds,  at a  purchase  price in cash equal to 100% of the  principal  amount
thereof on any Purchase Date plus accrued and unpaid interest  thereon,  if any,

for accepted  Securities),  any surplus Excess Proceeds that were the subject of
such offer shall cease to be Excess Proceeds,










                             6










and the Company may then use such amounts for general
corporate purposes.

                  Within  five  Business  days of the date the  amount of Excess
Proceeds  exceeds  $15,000,000,  the Company shall send, or cause to be sent, by
first-class  mail,  postage prepaid,  a notice regarding the Prepayment Offer to
each Holder of  Securities.  The Holder of this  Security may elect to have this
Security  or a  portion  hereof  in  an  authorized  denomination  purchased  by

owner of it for all purposes.

                  If money for the  payment of  principal  or  interest  remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its written  request unless an abandoned  property law designates
another Person. After any such payment,  Holders entitled to the money must look
only to the Company and not to the Trustee for payment.












                                      7










12.  Discharge and Defeasance

                  Subject to  certain  conditions,  the  Company at any time may
terminate some or all of its obligations  under the Securities and the Indenture
if the Company  deposits with the Trustee money or U.S.  Government  Obligations
for the payment of principal  and interest on the  Securities  to  redemption or
maturity, as the case may be.


13.  Amendment, Waiver

                  Subject to certain exceptions set forth in the Indenture,  (i)
the  Indenture  or the  Securities  may be amended  without  prior notice to any
Securityholder  but  with  the  written  consent  of the  Holders  of at least a
majority in principal  amount of the  outstanding  Securities  and (ii) any past
Default  and its  consequences  may be waived  with the  written  consent of the
Holders  of  at  least  a  majority  in  principal  amount  of  the  outstanding
Securities.  Subject to certain  exceptions set forth in the Indenture,  without
the consent of any Holder of  Securities,  the Company and the Trustee may amend
the Indenture or the Securities (i) to add additional  covenants or to surrender
rights and powers conferred on the Company;  (ii) to provide for  uncertificated
Securities  in  addition  to or in place of  certificated  Securities;  (iii) to
secure  the  Securities;  (iv)  to  cure  any  ambiguity,  omission,  defect  or
inconsistency;  (v) to make any change that does not adversely affect the rights
of any  Securityholder  in any  material  respect;  or (vi) to  comply  with the
requirements of the SEC in order to effect or maintain the  qualification of the
Indenture under the TIA.


14.  Defaults and Remedies

                  If an Event of Default occurs and is  continuing,  the Trustee
or the Holders of at least 25% in principal amount of the Securities, subject to
certain  limitations,  may declare all the Securities to be immediately  due and
payable.  Certain  events of bankruptcy or insolvency  are Events of Default and
shall  result in the  Securities  being  immediately  due and  payable  upon the
occurrence  of such Events of Default  without any further act of the Trustee or
any Holder.

                  Holders of Securities may not enforce the
Indenture or the Securities except as provided in the









                                    8










Indenture.  The Trustee may refuse to enforce the  Indenture  or the  Securities
unless  it  receives  reasonable  indemnity  or  security.  Subject  to  certain
limitations,  Holders of a majority in principal  amount of the  Securities  may
direct the Trustee in its  exercise  of any trust or power under the  Indenture.
The Holders of a majority in principal amount of the outstanding Securities,  by
written  notice to the Company and the Trustee,  may rescind any  declaration of
acceleration  and its consequences if the rescission would not conflict with any
judgment  or  decree,  and if all  Events of  Default  have been cured or waived
except  nonpayment of principal and interest that has become due solely  because
of the acceleration.


15.  Trustee Dealings with the Company

                  Subject to certain limitations imposed by the Act, the Trustee
under the  Indenture,  in its individual or any other  capacity,  may become the
owner  or  pledgee  of  Securities  and may  otherwise  deal  with  and  collect
obligations  owed to it by the Company or its  Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.


16.  No Recourse Against Others

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


17.  Authentication

                  This Security shall not be valid until an authorized signatory
of the Trustee (or an  authenticating  agent)  manually signs the certificate of
authentication on the other side of this Security.
