          in the Borough of Manhattan, The City of New York) specified in the
          notice prior to the close of business on the last Exchange Date and
          (B) represent that (x) it is not an affiliate of the Company as
          defined in Rule 405 under the 1933 Act, (y) such Registrable Security
          was acquired in the ordinary course of its business and (z) at the

               (v) that Holders will be entitled to withdraw their election, not
          later than the close of business on the last Exchange Date, by sending
          to the institution and at the address (located in the

                                       6
<PAGE>   7

          Borough of Manhattan, The City of New York) specified in the notice a
          telegram, telex, facsimile transmission or letter setting forth the
          name of such Holder, the principal amount of Registrable Securities
          delivered for exchange and a statement that such Holder is withdrawing
          his election to have such Securities exchanged.

                      As soon as practicable after the last Exchange Date, the
               Company shall:

                    (i) accept for exchange Registrable Securities or portions
               thereof tendered and not validly withdrawn pursuant to the
               Exchange Offer; and

                    (ii) deliver, or cause to be delivered, to the Trustee for
               cancellation all Registrable Securities or portions thereof so
               accepted for exchange by the Company and issue, and cause the
               Trustee to promptly authenticate and mail to each Holder, an
               Exchange Security equal in principal amount to the principal
               amount of the Registrable Securities surrendered by such Holder.

        The Company shall use its reasonable best efforts to complete the
Exchange Offer as provided above and shall comply with the applicable
requirements of the 1933 Act, the 1934 Act and other applicable laws and
regulations in connection with the Exchange Offer. The Exchange Offer shall not
be subject to any conditions, other than that the Exchange Offer does not
violate applicable law or any applicable interpretation of the Staff of the SEC.
The Company shall inform the Initial Purchasers of the names and addresses of
the Holders to whom the Exchange Offer is made, and the Initial Purchasers shall
have the right, subject to applicable law, to contact such Holders and otherwise
facilitate the tender of Registrable Securities in the Exchange Offer.

          (b) In the event that (i) the Company determines that the Exchange
     Offer Registration provided for in Section 2(a) above is not available or
     may not be consummated as soon as practicable after the last Exchange Date
     because it would violate applicable law or the applicable interpretations
     of the Staff of the SEC, (ii) the Exchange Offer is not for any other
     reason consummated within 270 days of the Issue Date or (iii) in the case
     of any Holder that participates in an Exchange Offer that has been
     completed, such Holder has not received, in the opinion of counsel for the
     Initial Purchasers, Exchange Securities on the Exchange Date that may be
     offered or sold without restriction under state and federal securities laws
     (other than due solely to the status of such Holder as an affiliate of the


                                       7
<PAGE>   8

     Company as defined in Rule 405 under the 1933 Act or as a broker-dealer),
     the Company shall (A) promptly deliver to the Holders written notice
     thereof and (B) use its reasonable best efforts to cause to be filed, at
     its sole expense, as soon as practicable after, and in no event later than
     90 days after, such determination, date or notice of such opinion of
     counsel is given to the Company, as the case may be, a Shelf Registration
     Statement providing for the sale by the Holders of all of the Registrable
     Securities and to have such Shelf Registration Statement declared effective
     by the SEC. In the event the Company is required to file a Shelf
     Registration Statement solely as a result of the matters referred to in
     clause (iii) of the preceding sentence, the Company shall use its
     reasonable best efforts to file and have declared effective by the SEC both
     an Exchange Offer Registration Statement pursuant to Section 2(a) with
     respect to all Registrable Securities and a Shelf Registration Statement
     (which may be a combined Registration Statement with the Exchange Offer
     Registration Statement) with respect to offers and sales of Registrable
     Securities held by the Initial Purchasers after completion of the Exchange
     Offer. The Company agrees to use its reasonable best efforts to keep the
     Shelf Registration Statement continuously effective until the earlier of
     two years (or, if Rule 144(k) is amended to provide a shorter restrictive
     period with respect to the Registrable Securities, such shorter period)
     after the Issue Date or such shorter period that will terminate when (A)
     all of the Registrable Securities covered by the Shelf Registration
     Statement have been sold pursuant to the Shelf Registration Statement or
     (B) in the case of clause (ii) of the first sentence of this Section 2(b),
     when the Exchange Offer is consummated. The Company further agrees to
     supplement or amend the Shelf Registration Statement if required by the
     rules, regulations or instructions applicable to the registration form used
     by the Company for such Shelf Registration Statement or by the 1933 Act or
     by any other rules and regulations thereunder for shelf registration or if
     reasonably requested by a Holder with respect to information relating to
     such Holder, and to use its reasonable best efforts to cause any such
     amendment to become effective and such Shelf Registration Statement to
     become usable as soon as thereafter practicable. The Company agrees to
     furnish to the Holders of Registrable Securities copies of any such
     supplement or amendment promptly after its being used or filed with the
     SEC.

          (c) The Company shall pay all Registration Expenses in connection with
     the registration pursuant to Section 2(a) and Section 2(b). Each Holder
     shall pay all underwriting discounts and commissions and transfer taxes, if
     any, relating to the sale or disposition of such Holder's Registrable
     Securities pursuant to the Shelf Registration Statement.


                                       8
<PAGE>   9


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

     In the event that (i) an Exchange Offer Registration Statement (or a Shelf
Registration Statement pursuant to Section 2(b)) is not filed with the SEC on or
prior to the 180th day following the Issue Date, (ii) an Exchange Offer
Registration Statement is not declared effective on or prior to the 240th day
following the Issue Date (unless a Shelf Registration Statement shall have been
filed pursuant to Section 2(b)) or (iii) the Exchange Offer is not consummated
or a Shelf Registration Statement is not declared effective on or prior to the
270th day following the Issue Date, the interest rate on the Securities will be
increased by 0.25% per annum from and including the next day following the
applicable period referred to in clauses (i) through (iii); provided that the
interest rate on the Securities pursuant to the foregoing will in no event
increase by more than 0.25% per annum in the aggregate; and provided further
that if the Exchange Offer Registration Statement is not declared effective on
or prior to the 240th day following the Issue Date and the Company requests
Holders of the Registrable Securities to provide the information as described in
Section 3(p), the Securities held by Holders who do not deliver such information
to the Company when so requested will not be entitled to any such increase in
the interest rate for any day after the 240th day following the Issue Date. Upon
(A) the filing of an Exchange Offer Registration Statement after the 180-day
period referred to in clause (i), (B) the effectiveness of an Exchange Offer
Registration Statement after the 240-day period referred to in clause (ii) or
(C) the consummation of the Exchange Offer or the effectiveness of a Shelf
Registration Statement, as the case may be, after the 270-day period referred to
in clause (iii), in each case the interest rate on the Securities from the day
of such filing, effectiveness or consummation, as the case may be, shall be
reduced to the original interest rate of the Securities as of the Issue Date.

     In the event that a Shelf Registration Statement is declared effective
pursuant to Section 2(b) and the Company fails to keep such Shelf Registration
Statement continuously effective or usable for resales for the period set forth
in

                                       9
<PAGE>   10

Section 2(b) due to any matter contemplated by Section 3(e)(v), and such failure
continues for more than 60 days (whether or not consecutive) in any twelve-month
period, then the interest rate on the Securities will be increased by 0.25% per
annum from the 61st day until the earlier of (x) the date that the Shelf
Registration Statement is again deemed effective or is usable, (y) the date that
is the second anniversary of the Issue Date (or, if Rule 144(k) is amended to
provide a shorter restrictive period, such shorter period), or (z) the date as
of which all the Securities are sold pursuant to the Shelf Registration
Statement.

          (e) Without limiting the remedies available to the Initial Purchasers
     and the Holders, the Company acknowledges that any failure by the Company
     to comply with its obligations under Section 2(a) and Section 2(b) hereof
     may result in material irreparable injury to the Initial Purchasers or the
     Holders for which there is no adequate remedy at law, that it will not be
     possible to measure damages for such injuries precisely and that, in the
     event of any such failure, the Initial Purchasers or any Holder may obtain
     such relief as may be required to specifically enforce the Company's
     obligations under Section 2(a) and Section 2(b) hereof.

     3. Registration Procedures.

     In connection with the obligations of the Company with respect to the
Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the
Company shall as expeditiously as possible:

          (a) prepare and file with the SEC a Registration Statement on the
     appropriate form under the 1933 Act, which form (x) shall be selected by
     the Company and (y) shall, in the case of a Shelf Registration, be
     available for the sale of the Registrable Securities by the selling Holders
     thereof and (z) shall comply as to form in all material respects with the
     requirements of the applicable form and include all financial statements
     required by the SEC to be filed therewith, and use its reasonable best
     efforts to cause such Registration Statement to become effective and remain
     effective in accordance with Section 2 hereof;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to each Registration Statement as may be necessary to keep such
     Registration Statement effective for the applicable period and cause each
     Prospectus to be supplemented by any required prospectus supplement and, as
     so supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to
     keep each Prospectus current during the period described under Section 4(3)
     and Rule 174 under the 1933 Act that is

                                       10
<PAGE>   11

     applicable to transactions by brokers or dealers with respect to the
     Registrable Securities or Exchange Securities;

          (c) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, to counsel for the Initial Purchasers, to counsel

     Registrable Securities, if any, without charge, as many copies of each
     Prospectus, including each preliminary Prospectus, and any amendment or
     supplement thereto and such other documents as such Holder or Underwriter
     may reasonably request, in order to facilitate the public sale or other
     disposition of the Registrable Securities; and the Company consents to the
     use of such Prospectus and any amendment or supplement thereto in
     accordance with applicable law by each of the selling Holders of
     Registrable Securities and any such Underwriters in connection with the
     offering and sale of the Registrable Securities covered by and in the
     manner described in such Prospectus or any amendment or supplement thereto
     in accordance with applicable law;

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

          (e) in the case of a Shelf Registration, notify each Holder of
     Registrable Securities, counsel for the Holders and counsel for the Initial
     Purchasers promptly and, if requested by any such Holder or counsel,
     confirm such advice in writing (i) when a Registration Statement has become
     effective and when any post-effective amendment thereto has been filed and

     effectiveness of a Registration Statement or the initiation of any
     proceedings for that purpose, (iv) if, between the effective date of a
     Registration Statement and the closing of any sale of Registrable
     Securities covered thereby, the representations and warranties of the
     Company contained in any underwriting agreement, securities sales agreement
     or other similar agreement, if any, relating to the offering cease to be
     true and correct in all material respects or if the Company receives any
     notification with respect to the suspension of the qualification of the
     Registrable Securities for sale in any jurisdiction or the initiation of
     any proceeding for such purpose, (v) of the happening of any event during
     the period a Shelf Registration Statement is effective which makes any
     statement made in such Registration Statement or the related Prospectus
     untrue in any material respect or which requires the making of any changes
     in such Registration Statement or Prospectus in order to make the
     statements therein not misleading, including (A) the fact that the
     Registration Statement or the related Prospectus contains an untrue
     statement of material fact or omits to state a material fact required or
     necessary in order to make the statements therein not misleading and (B)
     circumstances relating to pending corporate developments, public filings
     with the SEC and similar events that result in such Registration Statement
     not being continuously effective or usable for resales during the period
     set forth in Section 2(b) and (vi) of any determination by the Company that
     a post-effective amendment to a Registration Statement would be
     appropriate;

          (f) make every reasonable effort to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement at the earliest
     possible moment and provide immediate notice to each Holder of the
     withdrawal of any such order;

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


          (h) in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Securities to facilitate the timely preparation and
     delivery of certificates representing Registrable Securities to be sold and
     not bearing any restrictive legends and enable such Registrable Securities
     to be in such denominations (consistent with the provisions of the
     Indenture) and registered in such names as the selling Holders may


                                       12
<PAGE>   13

     reasonably request at least one business day prior to the closing of any
     sale of Registrable Securities;

          (i) in the case of a Shelf Registration, upon the occurrence of any
     matter contemplated by Section 3(e)(v) hereof, use its reasonable best
     efforts to prepare and file with the SEC a supplement or post-effective
     amendment to a Registration Statement or the related Prospectus or any
     document incorporated therein by reference or file any other required
     document so that, as thereafter delivered to the purchasers of the
     Registrable Securities, such Prospectus will not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements therein, in light of the circumstances under which they
     were made, not misleading. The Company agrees to notify the Holders to
     suspend use of the Prospectus as promptly as practicable after the
     occurrence of such an event, and the Holders hereby agree to suspend use of
     the Prospectus until the Company has amended or supplemented the Prospectus
     to correct such misstatement or omission. The Company will extend (A) the
     period set forth in Section 2(b) during which the Company is required to
     keep the Shelf Registration Statement effective and (B) the period set
     forth in Section 4(b)(i) during which Participating Broker-Dealers are
     authorized to use the Prospectus, by the number of days during the period
     from and including the date of the giving of such notice to and including
     the date when Holders receive copies of the supplemented or amended
     Prospectus necessary to permit resales of the Securities or to and
     including the date on which the Company has given notice that the sale of
     the Securities may be resumed, as the case may be;

          (j) a reasonable time prior to the filing of any Registration
     Statement, any Prospectus, any amendment to a Registration Statement or
     amendment or supplement to a Prospectus or any document which is to be
     incorporated by reference into a Registration Statement or a Prospectus
     after initial filing of a Registration Statement, provide copies of such
     document to the Initial Purchasers and their counsel (and, in the case of a
     Shelf Registration Statement, the Holders and their counsel) and make such
     of the representatives of the Company as shall be reasonably requested by
     the Initial Purchasers or their counsel (and, in the case of a Shelf
     Registration Statement, the Holders or their counsel) available for
     discussion of such document, and shall not at any time file or make any
     amendment to the Registration Statement, any Prospectus or any amendment of
     or supplement to a Registration Statement or a Prospectus or any document
     which is to be incorporated by reference into a Registration Statement or a
     Prospectus, of which the Initial Purchasers and their counsel (and, in the
     case of a Shelf Registration Statement, the

                                       13
<PAGE>   14

     Holders and their counsel) shall not have previously been advised and
     furnished a copy or to which the Initial Purchasers or their counsel (and,
     in the case of a Shelf Registration Statement, the Holders or their
     counsel) shall object, except for any amendment or supplement or document
     (a copy of which has been previously furnished to the Initial Purchasers
     and their counsel (and, in the case of a Shelf Registration Statement, the
     Holders and their counsel)) which counsel to the Company shall advise the
     Company in writing is required in order to comply with applicable law;

          (k) obtain a CUSIP number for all Exchange Securities or Registrable
     Securities, as the case may be, not later than the effective date of a
     Registration Statement;

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

          (m) in the case of a Shelf Registration, make available for inspection
     by a representative of the Holders of the Registrable Securities, any
     Underwriter participating in any disposition pursuant to such Shelf
     Registration Statement, and attorneys and accountants designated by the
     Holders, at reasonable times and in a reasonable manner, all financial and
     other records, pertinent documents and properties of the Company, and cause
     the respective officers, directors and employees of the Company to supply
     all information reasonably requested by any such representative,
     Underwriter, attorney or accountant in connection with a Shelf Registration
     Statement;

          (n) in the case of a Shelf Registration, use its reasonable best
     efforts to cause all Registrable Securities to be listed on any securities
     exchange or any automated quotation system on which similar securities
     issued by the Company are then listed if requested by the Majority Holders,
     to the extent such Registrable Securities satisfy applicable listing
     requirements;


                                       14
<PAGE>   15


          (o) if reasonably requested by any Holder of Registrable Securities
     covered by a Registration Statement, (i) promptly incorporate in a
     Prospectus supplement or post-effective amendment such information with
     respect to such Holder as such Holder reasonably requests to be included
     therein and (ii) make all required filings of such Prospectus supplement or
     such post-effective amendment as soon as the Company has received
     notification of the matters to be incorporated in such filing; and

          (p) in the case of a Shelf Registration, enter into such customary
     agreements and take all such other actions in connection therewith
     (including those requested by the Holders of a majority of the Registrable
     Securities being sold) in order to expedite or facilitate the disposition
     of such Registrable Securities including, but not limited to, an
     Underwritten Offering and in such connection, (i) to the extent possible,
     make such representations and warranties to the Holders and any
     Underwriters of such Registrable Securities with respect to the business of
     the Company and its subsidiaries, the Registration Statement, Prospectus
     and documents incorporated by reference or deemed incorporated by
     reference, if any, in each case, in form, substance and scope as are
     customarily made by issuers to underwriters in underwritten offerings and
     confirm the same if and when requested, (ii) obtain opinions of counsel to
     the Company (which counsel and opinions, in form, scope and substance,
     shall be reasonably satisfactory to the Holders and such Underwriters and
     their respective counsel) addressed to each selling Holder and Underwriter
     of Registrable Securities, covering the matters customarily covered in
     opinions requested in underwritten offerings, (iii) obtain "COLD COMFORT"
     letters from the independent certified public accountants of the Company
     (and, if necessary, any other certified public accountant of any subsidiary
     of the Company, or of any business acquired by the Company for which
     financial statements and financial data are or are required to be included
     in the Registration Statement) addressed to each selling Holder and
     Underwriter of Registrable Securities, such letters to be in customary form
     and covering matters of the type customarily covered in "COLD COMFORT"
     letters in connection with underwritten offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders of
     a majority in principal amount of the Registrable Securities being sold or
     the Underwriters, and which are customarily delivered in underwritten
     offerings, to evidence the continued validity of the representations and
     warranties of the Company made pursuant to clause (i) above and to evidence
     compliance with any customary conditions contained in an underwriting
     agreement.


                                       15
<PAGE>   16


     In the case of a Shelf Registration Statement, (A) a Holder that sells
Registrable Securities pursuant to such Shelf Registration Statement will be
required to be named as a selling security holder in the related Prospectus and
(B) the Company may require each Holder of Registrable Securities to furnish to
the Company such information regarding the Holder and the proposed distribution
by such Holder of such Registrable Securities as the Company may from time to
time reasonably request in writing. The Company will not have any obligation to
include in the Shelf Registration Statement any Holder that does not deliver
such information to the Company.

     In the case of a Shelf Registration Statement, each Holder agrees that,
upon receipt of any notice from the Company of the happening of any event of the
kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to a Registration Statement until
such Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof, and, if so directed by the Company, such
Holder will deliver to the Company (at its expense) all copies in its
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice. If the Company shall give any such notice to suspend the
disposition of Registrable Securities pursuant to a Registration Statement, the
Company shall extend the period during which the Registration Statement shall be
maintained effective pursuant to this Agreement by the number of days during the
period from and including the date of the giving of such notice to and including
the date when the Holders shall have received copies of the supplemented or
amended Prospectus necessary to resume such dispositions. The Company may give
any such notice only twice during any 365 day period and any such suspensions
may not exceed 30 days for each suspension and there may not be more than two
suspensions in effect during any 365 day period.

     The Holders of Registrable Securities covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment banker
or investment bankers and manager or managers (the "UNDERWRITERS") that will
administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering.

     4. Participation of Broker-Dealers in Exchange Offer.


          (a) The Staff of the SEC has taken the position that any broker-
     dealer that receives Exchange Securities for its own account in the
     Exchange Offer in exchange for Securities that were acquired by such
     broker-dealer as a result of market-making or other trading activities (a


                                       16
<PAGE>   17

     "PARTICIPATING BROKER-DEALER"), may be deemed to be an "UNDERWRITER" within
     the meaning of the 1933 Act and must deliver a prospectus meeting the
     requirements of the 1933 Act in connection with any resale of such Exchange
     Securities.

     The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Securities, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Securities owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Securities for their own accounts, so
long as the Prospectus otherwise meets the requirements of the 1933 Act.

          (b) In light of the above, notwithstanding the other provisions of
     this Agreement, the Company agrees that the provisions of this Agreement as
     they relate to a Shelf Registration shall also apply to an Exchange Offer
     Registration to the extent, and with such reasonable modifications thereto
     as may be, reasonably requested by the Initial Purchasers or by one or more
     Participating Broker-Dealers, in each case as provided in clause (ii)
     below, in order to expedite or facilitate the disposition of any Exchange
     Securities by Participating Broker-Dealers consistent with the positions of
     the Staff recited in Section 4(a) above; provided that:

               (i) the Company shall not be required to amend or supplement the
          Prospectus contained in the Exchange Offer Registration Statement, as
          would otherwise be contemplated by Section 3(i), for a period
          exceeding 240 days after the last Exchange Date (as such period may be
          extended pursuant to the penultimate paragraph of Section 3 of this
          Agreement) and Participating Broker-Dealers shall not be authorized by
          the Company to deliver and shall not deliver such Prospectus after
          such period in connection with the resales contemplated by this
          Section 4; and

               (ii) the application of the Shelf Registration procedures set
          forth in Section 3 of this Agreement to an Exchange Offer
          Registration, to the extent not required by the positions of the Staff
          of the SEC or the 1933 Act and the rules and regulations thereunder,
          will be in conformity with the reasonable request to the Company by
          the Initial Purchasers or with the reasonable request in writing to
          the Company by one or more broker-dealers who

                                       17
<PAGE>   18

          certify to the Initial Purchasers and the Company in writing that they
          anticipate that they will be Participating Broker-Dealers; and
          provided further that, in connection with such application of the
          Shelf Registration procedures set forth in Section 3 to an Exchange
          Offer Registration, the Company shall be obligated (x) to pay the fees
          and expenses of only one counsel representing the Participating
          Broker-Dealers, which shall be counsel to the Initial Purchasers
          unless such counsel elects not to so act and (y) to cause to be
          delivered only one, if any, "COLD COMFORT" letter with respect to the
          Prospectus in the form existing on the last Exchange Date and with
          respect to each subsequent amendment or supplement, if any, effected
          during the period specified in clause (i) above.

     (c) The Initial Purchasers shall have no liability to the Company or any
Holder with respect to any request that it may make pursuant to Section 4(b)
above.

     5. Indemnification and Contribution.

          (a) The Company agrees to indemnify and hold each Initial Purchaser,
     each Holder and each Person, if any, who controls any Initial Purchaser or
     any Holder within the meaning of Section 15 of the Act or Section 20 of the
     Exchange Act, harmless from and against any and all losses, claims,
     damages, and liabilities arising because any Registration Statement (or any
     amendment thereto) pursuant to which Exchange Securities or Registrable
     Securities were registered under the 1933 Act, including all documents
     incorporated therein by reference, or any Prospectus (as amended or
     supplemented if the Company shall have furnished any amendments or
     supplements thereto) contained or is alleged to have contained any untrue
     statement of a material fact or omitted or is alleged to have omitted to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading, except as to losses, claims, damages
     or liabilities caused by any such untrue statement or omission or alleged
     untrue statement or omission made in reliance upon information furnished to
     the Company herein or otherwise in writing by or on behalf of any Initial
     Purchaser of any Holder for use therein. In connection with any
     Underwritten Offering permitted by Section 3, the Company will also
     indemnify the Underwriters, if any, selling brokers, dealers and similar
     securities industry professionals participating in the distribution, their
     officers and directors and each Person who controls such Persons (within
     the meaning of the 1933 Act and the 1934 Act) to the same extent as
     provided above with respect to the indemnification of the Holders, if
     requested in connection with any Registration Statement.


                                       18
<PAGE>   19


          (b) In the event that any Registration Statement is filed pursuant to
     this Agreement prior to the consummation of the split-off of AT&T Wireless
     Group from AT&T, as described in the Offering Memorandum, AT&T agrees to
     indemnify and hold each Initial Purchaser, each Holder and each Person, if
     any, who controls any Initial Purchaser or Holder within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, harmless from and
     against any and all losses, claims, damages, and liabilities arising
     because any Registration Statement (or any amendment thereto) pursuant to
     which Exchange Securities or Registrable Securities were registered under
     the 1933 Act, including all documents incorporated therein by reference, or
     any Prospectus (as amended or supplemented if the Company shall have
     furnished any amendments or supplements thereto) contained or is alleged to
     have contained any untrue statement of a material fact or omitted or is
     alleged to have omitted to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, which
     untrue statement or omission or alleged untrue statement or omission was
     made in the Registration Statement (or any amendment thereto), including
     all documents incorporated therein by reference , or the Prospectus or any
     amendment or supplement thereto in reliance upon information furnished to
     the Company herein or otherwise in writing by or on behalf of AT&T for use
     in connection with the preparation thereof.

          (c) Each Holder agrees, severally and not jointly, to indemnify and
     hold the Company and AT&T, the Initial Purchasers and the other selling
     Holders, and each of their respective directors, officers who sign the
     Registration Statement, and each Person who controls the Company, AT&T, any
     Initial Purchaser and any other selling Holder within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, harmless from and
     against any and all losses, claims, damages and liabilities arising because
     any Registration Statement (or any amendment thereto) pursuant to which
     Exchange Securities or Registrable Securities were registered under the
     1933 Act, including all documents incorporated therein by reference, or any
     Prospectus (as amended or supplemented if the Company shall have furnished
     any amendments or supplements thereto) contained any untrue statement of a
     material fact or omitted or is alleged to have omitted to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, which untrue statement or omission or alleged
     untrue statement or omission was made in the Registration Statement (or any
     amendment thereto), including all documents incorporated therein by
     reference, or the Prospectus or any amendment or supplement thereto in
     reliance upon information furnished

                                       19
<PAGE>   20

     to the Company herein or otherwise in writing by or on behalf of such
     Initial Purchaser for use in connection with the preparation thereof.

          (d) Upon the commencement of any action against any Person in respect
     of which indemnity may be sought on account of any indemnity agreement
     contained herein, such Person or any Person controlling such Person as
     aforesaid, will promptly give written notice of the commencement thereof to
     the party or parties against whom indemnity shall be sought, but the
     omission so to notify such indemnifying party or parties of any such action
     shall not relieve such indemnifying party or parties from any liability
     which it or they may have to the indemnified party or parties otherwise
     than on account of such indemnity agreement. In case such notice of any
     such action shall be so given, such indemnifying party or parties shall be
     entitled to participate at its or their own expense in the defense of such
     action, or, if it or they so elect, to assume the defense of such action,
     and in the latter event such defense shall be conducted by counsel chosen
     by such indemnifying party or parties and satisfactory to the indemnified
     party or parties who shall be defendant or defendants in such action, and
     such defendant or defendants shall bear the fees and expenses of any
     additional counsel retained by them; but if the indemnifying party or
     parties shall not elect to assume the defense of such action, such
     indemnifying party or parties will reimburse such indemnified party or
     parties for the reasonable fees and expenses of any counsel retained by
     them. In the event that the parties to any such action (including impleaded
     parties) include both the indemnifying party and the indemnified party and
     either (i) the indemnifying party or parties and indemnified party or
     parties mutually agree or (ii) representation of both the indemnifying
     party or parties and the indemnified party or parties by the same counsel
     is inappropriate under applicable standards of professional conduct due to
     actual or potential differing interests between them, then the indemnifying
     party or parties shall not have the right to assume the defense of such
     action on behalf of such indemnified party or parties and will reimburse
     such indemnified party or parties for the reasonable fees and expenses of
     any counsel retained by them and satisfactory to the indemnifying party or
     parties, it being understood that the indemnifying party or parties shall
     not, in connection with any one action or separate but similar or related
     actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the reasonable fees and
     expenses of more than one separate firm of attorneys for all such
     indemnified parties, which firm shall be designated in writing by Merrill
     Lynch, Pierce, Fenner & Smith Incorporated and Salomon Smith Barney Inc.,
     jointly, in the case of an action in which one or more Initial Purchasers,
     or controlling persons are indemnified parties,


                                       20
<PAGE>   21

     by the Majority Holders in the case of an action in which the Holders, or
     controlling persons are indemnified parties, and by the Company or AT&T in
     the case of an action in which the Company or AT&T or any of their
     directors, officers or controlling persons are indemnified parties. The
     indemnifying party or parties shall not be liable under this Agreement with
     respect to any settlement made by any indemnified party or parties without
     prior written consent by the indemnifying party or parties to such
     settlement.

          (e) If the indemnification provided for in paragraph (a) or (c) of
     this Section 5 is unavailable to an indemnified party in respect of any
     losses, claims, damages, or liabilities referred to therein, then each
     indemnifying party under such paragraph, in lieu of indemnifying such
     indemnified party thereunder, shall contribute to the amount paid or
     payable by such indemnified party as a result of such losses, claims,
     damages or liabilities in such proportion as is appropriate to reflect the
     relative fault of the indemnified party or parties on the one hand and the
     indemnified party or parties on the other in connection with the statements
     or omissions or alleged statements or omissions which resulted in such
     losses, claims, damages, or liabilities, as well as any other relevant
     equitable considerations. The relative fault of the Company on the one hand
     and of the Holders on the other shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by the Company or by the Holders and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such statement or omission. The Company and each Holder
     agree that it would not be just and equitable if contribution pursuant to
     this paragraph (e) were determined by pro rata allocation (even if the
     Holders were treated as one entity for such purpose) or by any other method
     of allocation which does not take account of the equitable considerations
     referred to above in this paragraph (e). The amount paid or payable by an
     indemnified party as a result of the losses, claims, damages or liabilities
     referred to in this paragraph (e) shall be deemed to include, subject to
     the limitations set forth above in this Section 5, any legal or other
     expenses reasonably incurred by such indemnified party in connection with
     defending any such action or claim. Notwithstanding the provisions of this
     paragraph (e), no Holder shall be required to contribute any amount in
     excess of the amount by which the total price at which the Registrable
     Securities were sold by such Holder exceeds the amount of any damages which
     such Holder has been required to pay, otherwise than pursuant to this
     paragraph (e), by reason of such untrue or alleged untrue statement or
     omission or alleged omission. No Person guilty of fraudulent


                                       21
<PAGE>   22

     misrepresentation (within the meaning of Section 11(e) of the 1933 Act)
     shall be entitled to contribution from any Person who was not guilty of
     such fraudulent misrepresentation.

          (f) In the event that any Registration Statement is filed pursuant to
     this Agreement prior to the consummation of the split-off of AT&T Wireless
     Group from AT&T, as described in the Offering Memorandum, AT&T agrees with
     each Initial Purchaser and Holder that, in the event amounts are payable by
     the Company under paragraphs (a) or (e) of this Section 11, and the Company
     is unable to satisfy these obligations, AT&T will satisfy these obligations
     to the extent they remain unpaid by the Company.

          (g) Notwithstanding anything to the contrary in this Agreement, in the
     event that the split-off of AT&T Wireless Group from AT&T, as described in
     the Offering Memorandum, is consummated prior to the date that any
     Registration Statement under this Agreement is declared effective, the
     obligations of AT&T under this Agreement shall terminate.

     The indemnity and contribution provisions contained in this Section 5 shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of the Initial
Purchasers, any Holder or any Person controlling any Initial Purchaser or any
Holder, or by or on behalf of the Company, its officers or directors or any
Person controlling the Company, (iii) acceptance of any of the Exchange
Securities and (iv) any sale of Registrable Securities pursuant to a Shelf
Registration Statement.

     6. Miscellaneous.

          (a) No Inconsistent Agreements. The Company has not entered into, and
     on or after the date of this Agreement will not enter into, any agreement
     which is inconsistent with the rights granted to the Holders of Registrable
     Securities in this Agreement or otherwise conflicts with the provisions
     hereof. The rights granted to the Holders hereunder do not in any way
     conflict with and are not inconsistent with the rights granted to the
     holders of the Company's other issued and outstanding securities under any
     such agreements.

          (b) Amendments and Waivers. The provisions of this Agreement,
     including the provisions of this sentence, may not be amended, modified or
     supplemented, and waivers or consents to departures from the provisions
     hereof may not be given unless the Company has obtained the written consent
     of Holders of at least a majority

                                       22
<PAGE>   23

     in aggregate principal amount of the outstanding Registrable Securities
     affected by such amendment, modification, supplement, waiver or consent;
     provided, however, that no amendment, modification, supplement, waiver or
     consent to any departure from the provisions of Section 5 hereof shall be
     effective as against any Holder of Registrable Securities unless consented
     to in writing by such Holder.

          (c) Notices. All notices and other communications provided for or
     permitted hereunder shall be made in writing by hand-delivery, registered
     first-class mail, telex, telecopier, or any courier guaranteeing overnight
     delivery (i) if to a Holder, at the most current address given by such
     Holder to the Company by means of a notice given in accordance with the
     provisions of this Section 6(c), which address initially is, with respect
     to the Initial Purchasers, the addresses set forth in the Purchase
     Agreement; and (ii) if to the Company, initially at the Company's address
     set forth in the Purchase Agreement and thereafter at such other address,
     notice of which is given in accordance with the provisions of this Section
     6(c).

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

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

          (d) Successors and Assigns. This Agreement shall inure to the benefit
     of and be binding upon the successors, assigns and transferees of each of
     the parties, including, without limitation and without the need for an
     express assignment, subsequent Holders; provided that nothing herein shall
     be deemed to permit any assignment, transfer or other disposition of
     Registrable Securities in violation of the terms of the Purchase Agreement.
     If any transferee of any Holder shall acquire Registrable Securities, in
     any manner, whether by operation of law or otherwise, such Registrable
     Securities shall be held subject to all of the terms of this Agreement, and
     by taking and holding such Registrable Securities such Person shall be
     conclusively deemed to have agreed to be bound by and to perform all of the
     terms and provisions of this Agreement and such Person shall be entitled to
     receive the benefits hereof. The Initial Purchasers (in their capacity as
     Initial Purchasers) shall have no liability or obligation to the

                                       23

     breach by any Holder of, any of the obligations of such Holder under this
     Agreement.

          (e) Purchases and Sales of Securities. The Company shall not, and
     shall use its reasonable best efforts to cause its affiliates (as defined
     in Rule 405 under the 1933 Act) not to, purchase and then resell or
     otherwise transfer any Securities.

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

          (g) Counterparts. This Agreement may be executed in any number of
     counterparts and by the parties hereto in separate counterparts, each of
     which when so executed shall be deemed to be an original and all of which
     taken together shall constitute one and the same ageement.

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

          (i) Governing Law. This Agreement shall be governed by the laws of the
     State of New York.

          (j) Severability. In the event that any one or more of the provisions
     contained herein, or the application thereof in any circumstance, is held
     invalid, illegal or unenforceable, the validity, legality and
     enforceability of any such provision in every other respect and of the
     remaining provisions contained herein shall not be affected or impaired
     thereby.
