                                  4(2) PROGRAM

         This agreement ("Agreement") sets forth the understandings between AT&T
Wireless Services, Inc. (the "Issuer") and ______________, as dealer for Notes
(as such term is defined below) (the "Dealer"), each named on the cover page
hereof, in connection with the issuance and sale by the Issuer of its short-term
promissory notes (the "Notes") through the Dealer.

         Certain terms used in this Agreement are defined in Section 6 hereof.

         The Addendum to this Agreement, and any Annexes or Exhibits described
in this Agreement or such Addendum, are hereby incorporated into this Agreement
and made fully a part hereof.

1.       OFFERS, SALES AND RESALES OF NOTES

         1.1 While (i) the Issuer has and shall have no obligation to sell the
Notes to the Dealer or to permit the Dealer to arrange any sale of the Notes for
the account of the Issuer, and (ii) the Dealer has and shall have no obligation
to purchase the Notes from the Issuer or to arrange any sale of the Notes for
the account of the Issuer, the parties hereto agree that in any case where a
Dealer purchases Notes from the Issuer, or arranges for the sale of Notes by the
Issuer, such Notes will be purchased or sold by such Dealer in reliance on the
representations, warranties, covenants and agreements of the Issuer contained
herein or made pursuant hereto and on the terms and conditions and in the manner
provided herein.

         1.2 So long as this Agreement shall remain in effect, and in addition
to the limitations contained in Section 1.7 hereof, the Issuer shall not,
without the consent of the Dealer, offer, solicit or accept offers to purchase,
or sell, any Notes except (a) in transactions with one or more dealers which may
from time to time after the date hereof become dealers with respect to the Notes
by executing with the Issuer one or more agreements which contain provisions
substantially identical to those contained in Section 1 of this Agreement, of
which the Issuer hereby undertakes to provide the Dealer prompt notice, (b) in
transactions with the other dealers listed on the Addendum hereto, which are
executing agreements with the Issuer which contain provisions substantially
identical to Section 1 of this Agreement contemporaneously herewith or (c) in
accordance with Section 1.6(i) hereof. In no event shall the Issuer offer,
solicit or accept offers to purchase, or sell, any Notes directly on its own
behalf in transactions with persons other than broker-dealers as specifically
permitted in this Section 1.2.

         1.3 The Notes shall be in a minimum denomination of $250,000 or
integral multiples of $1,000 in excess thereof, will bear such interest rates,
if interest bearing, or will be sold at such discount from their face amounts,
as shall be agreed upon by the applicable Dealer and the Issuer, shall have a
maturity not exceeding 365 days from the date of issuance
<PAGE>   3
(exclusive of days of grace), and shall not contain any provision for extension,
renewal or automatic "rollover."

         1.4 The authentication and issuance of, and payment for, the Notes
shall be effected in accordance with the Issuing and Paying Agency Agreement,
and the Notes shall be either individual physical certificates or book-entry
notes evidenced by a Master Note (as such term is defined in the Issuing and
Paying Agency Agreement) registered in the name of DTC or its nominee, in the
form or forms annexed to the Issuing and Paying Agency Agreement.

         1.5 If the Issuer and a Dealer shall agree on the terms of the purchase
of any Note by such Dealer or the sale of any Note arranged by such Dealer
(including, but not limited to, agreement with respect to the date of issue,
purchase price, principal amount, maturity and interest rate (in the case of
interest-bearing Notes) or discount thereof (in the case of Notes issued on a
discount basis), and appropriate compensation for such Dealer's services
hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be
issued and delivered in accordance with the terms of the Issuing and Paying
Agency Agreement and payment for such Note shall be made by the purchaser
thereof, either directly or through such Dealer, to the Issuing and Paying
Agent, for the account of the Issuer. Except as otherwise agreed, in the event
that a Dealer is acting as an agent and a purchaser shall either fail to accept
delivery of or make payment for a Note on the date fixed for settlement, such
Dealer shall promptly notify the Issuer, and if such Dealer has theretofore paid
the Issuer for the Note, the Issuer will promptly return such funds to such
Dealer against its return of the Note to the Issuer, in the case of a
certificated Note, and upon notice of such failure in the case of a book-entry
Note. If such failure occurred for any reason other than default by a Dealer,
the Issuer shall reimburse such Dealer on an equitable basis for such Dealer's
loss of the use of such funds for the period such funds were credited to the
Issuer's account.

         1.6 The Dealer and the Issuer hereby establish and agree to observe the
following procedures in connection with offers, sales and subsequent resales or
other transfers of the Notes:

                  (a) Offers and sales of the Notes by or through a Dealer shall
be made only to: (i) investors reasonably believed by such Dealer to be
Qualified Institutional Buyers, Institutional Accredited Investors or
Sophisticated Individual Accredited Investors and (ii) non-bank fiduciaries or
agents that will be purchasing Notes for one or more accounts, each of which is
reasonably believed by such Dealer to be an Institutional Accredited Investor or
Sophisticated Individual Accredited Investor.

                  (b) Resales and other transfers of the Notes by the holders
thereof shall be made only in accordance with the restrictions in the legend
described in clause (e) below.

                  (c) No general solicitation or general advertising shall be
used in connection with the offering of the Notes. Without limiting the
generality of the foregoing, without the prior written approval of the Dealer,
the Issuer shall not issue any press release or place or publish any "tombstone"
or other advertisement relating to the Notes.
<PAGE>   4
                  (d) No sale of Notes to any one purchaser shall be for less
than $250,000 principal or face amount, and no Note shall be issued in a smaller
principal or face amount. If the purchaser is a non-bank fiduciary acting on
behalf of others, each person for whom such purchaser is acting must purchase at
least $250,000 principal or face amount of Notes.

                  (e) Offers and sales of the Notes by the Issuer through a
Dealer acting as agent for the Issuer shall be made in accordance with Rule 506
under the Securities Act, and shall be subject to the restrictions described in
the legend appearing on Exhibit A hereto. A legend substantially to the effect
of such Exhibit A shall appear as part of the Private Placement Memorandum used
in connection with offers and sales of Notes hereunder, as well as on each
individual certificate representing a Note and each Master Note representing
book-entry Notes offered and sold pursuant to this Agreement.

                  (f) A Dealer shall furnish or shall have furnished to each
purchaser of Notes for which it has acted as the Dealer a copy of the
then-current Private Placement Memorandum unless such purchaser has previously
received a copy of the Private Placement Memorandum as then in effect. The
Private Placement Memorandum shall expressly state that any person to whom Notes
are offered shall have an opportunity to ask questions of, and receive
information from, the Issuer and such Dealer and shall provide the names,
addresses and telephone numbers of the persons from whom information regarding
the Issuer may be obtained.

                  (g) The Issuer agrees, for the benefit of the Dealer and each
of the holders and prospective purchasers from time to time of the Notes that,
if at any time the Issuer shall not be subject to Section 13 or 15(d) of the
Exchange Act, the Issuer will furnish, upon request and at its expense, to the
Dealer and to holders and prospective purchasers of Notes information required
by Rule 144A(d)(4)(i) in compliance with Rule 144A(d).

                  (h) In the event that any Note offered or to be offered by a
Dealer would be ineligible for resale under Rule 144A, the Issuer shall
immediately notify such Dealer (by telephone, confirmed in writing) of such fact
and shall promptly prepare and deliver to such Dealer an amendment or supplement
to the Private Placement Memorandum describing the Notes that are ineligible,
the reason for such ineligibility and any other relevant information relating
thereto.

                  (i) The Issuer represents that it may issue commercial paper
in the United States market in reliance upon, and in compliance with, the
exemption provided by Section 3(a)(3) of the Securities Act. If it does so, the
Issuer agrees that (a) the proceeds from the sale of the Notes will be
segregated from the proceeds of the sale of any such commercial paper by being
placed in a separate account; (b) the Issuer will institute appropriate
corporate procedures to ensure that the offers and sales of notes issued by the
Issuer pursuant to the Section 3(a)(3) exemption are not integrated with
offerings and sales of Notes hereunder; and (c) the Issuer will comply with each
of the requirements of Section 3(a)(3) of the Act in selling commercial paper or
other short-term debt securities other than the Notes in the United States.
<PAGE>   5
         1.7 The Issuer hereby represents and warrants to the Dealer, in
connection with offers, sales and resales of Notes, as follows:

                  (a) Issuer hereby confirms to the Dealer that (except as
permitted by Section 1.6(i)) within the preceding six months neither the Issuer
nor any person other than the Dealer or the other dealers referred to in Section
1.2 hereof acting on behalf of the Issuer has offered or sold any Notes, or any
substantially similar security of the Issuer (including, without limitation,
medium-term notes issued by the Issuer), to, or solicited offers to buy any such
security from, any person other than the Dealer or the other dealers referred to
in Section 1.2 hereof. The Issuer also agrees that (except as permitted by
Section 1.6(i)), as long as the Notes are being offered for sale by the Dealer
and the other dealers referred to in Section 1.2 hereof as contemplated hereby
and until at least six months after the offer of Notes hereunder has been
terminated, neither the Issuer nor any person other than the Dealer or the other
dealers referred to in Section 1.2 hereof (except as contemplated by Section 1.2
hereof) will offer the Notes or any substantially similar security of the Issuer
for sale to, or solicit offers to buy any such security from, any person other
than the Dealer or the other dealers referred to in Section 1.2 hereof, it being
understood that such agreement is made with a view to bringing the offer and
sale of the Notes within the exemption provided by Section 4(2) of the
Securities Act and shall survive any termination of this Agreement. The Issuer
hereby represents and warrants that it has not taken or omitted to take, and
will not take or omit to take, any action that would cause the offering and sale
of Notes hereunder to be integrated with any other offering of securities,
whether such offering is made by the Issuer or some other party or parties.

                  (b) The Issuer represents and agrees that the proceeds of the
sale of the Notes are not currently contemplated to be used for the purpose of
buying, carrying or trading securities within the meaning of Regulation T and
the interpretations thereunder by the Board of Governors of the Federal Reserve
System. In the event that the Issuer determines to use such proceeds for the
purpose of buying, carrying or trading securities, whether in connection with an
acquisition of another company or otherwise, the Issuer shall give the Dealer at
least five business days' prior written notice to that effect. The Issuer shall
also give the Dealer prompt notice of the actual date that it commences to
purchase securities with the proceeds of the Notes. Thereafter, in the event
that a Dealer purchases Notes as principal and does not resell such Notes on the
day of such purchase, to the extent necessary to comply with Regulation T and
the interpretations thereunder, such Dealer will sell such Notes either (i) only
to offerees it reasonably believes to be QIBs or to QIBs it reasonably believes
are acting for other QIBs, in each case in accordance with Rule 144A or (ii) in
a manner which would not cause a violation of Regulation T and the
interpretations thereunder.

2.       REPRESENTATIONS AND WARRANTIES OF ISSUER

         The Issuer represents and warrants to the Dealer:

         2.1 The Issuer is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation and has
all the requisite power
<PAGE>   6
and authority to execute, deliver and perform its obligations under the Notes,
this Agreement and the Issuing and Paying Agency Agreement.

         2.2 This Agreement and the Issuing and Paying Agency Agreement have
been duly authorized, executed and delivered by the Issuer and constitute legal,
valid and binding obligations of the Issuer enforceable against the Issuer in
accordance with their terms, subject to applicable bankruptcy, insolvency and
similar laws affecting creditors' rights generally, and subject, as to
enforceability, to general principles of equity (regardless of whether
enforcement is sought in a proceeding in equity or at law).

         2.3 The Notes have been duly authorized, and when issued as provided in
the Issuing and Paying Agency Agreement, will be duly and validly issued and
will constitute legal, valid and binding obligations of the Issuer enforceable
against the Issuer in accordance with their terms, subject to applicable
bankruptcy, insolvency and similar laws affecting creditors' rights generally,
and subject, as to enforceability, to general principles of equity (regardless
of whether enforcement is sought in a proceeding in equity or at law).

         2.4 The offer and sale of Notes in the manner contemplated hereby do
not require registration of the Notes under the Securities Act, pursuant to the
exemption from registration contained in Section 4(2) thereof, and no indenture
in respect of the Notes is required to be qualified under the Trust Indenture
Act of 1939, as amended.

         2.5 The Notes will rank at least pari passu with all other unsecured
and unsubordinated indebtedness of the Issuer.

         2.6 No consent or action of, or filing or registration with, any
governmental or public regulatory body or authority, including the SEC, is
required to authorize, or is otherwise required in connection with the
execution, delivery or performance of, this Agreement, the Notes or the Issuing
and Paying Agency Agreement, except as may be required by the securities or Blue
Sky laws of the various states in connection with the offer and sale of the
Notes.

         2.7 Neither the execution and delivery of this Agreement and the
Issuing and Paying Agency Agreement, nor the issuance of the Notes in accordance
with the Issuing and Paying Agency Agreement, nor the fulfillment of or
compliance with the terms and provisions hereof or thereof by the Issuer, will
(i) result in the creation or imposition of any mortgage, lien, charge or
encumbrance of any nature whatsoever upon any of the properties or assets of the
Issuer, or (ii) violate or result in a breach or a default under any of the
terms of the Issuer's charter documents or by-laws, any contract or instrument
to which the Issuer is a party or by which it or its property is bound, or any
law or regulation, or any order, writ, injunction or decree of any court or
government instrumentality, to which the Issuer is subject or by which it or its
property is bound, which breach or default might have a material adverse effect
on the condition (financial or otherwise), operations or business prospects of
the Issuer or the ability of the Issuer to perform its obligations under this
Agreement, the Notes or the Issuing and Paying Agency Agreement.
<PAGE>   7
         2.8 The Issuer is not an "investment company" or an entity "controlled"
by an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

         2.9 The Private Placement Memorandum delivered to investors in
connection with any sale of Notes will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

         2.10 Each (a) issuance of Notes by the Issuer hereunder and (b)
amendment or supplement of the Private Placement Memorandum shall be deemed a
representation and warranty by the Issuer to the applicable Dealer, as of the
date thereof, that, both before and after giving effect to such issuance and
after giving effect to such amendment or supplement, the representations and
warranties given by the Issuer set forth above in this Section 2 remain true and
correct on and as of such date as if made on and as of such date.

3.       COVENANTS AND AGREEMENTS OF ISSUER

         The Issuer covenants and agrees that:

         3.1 The Issuer will give the Dealer prompt notice (but in any event
prior to any subsequent issuance of Notes hereunder) of any amendment to,
modification of or waiver with respect to, the Notes or the Issuing and Paying
Agency Agreement, including a complete copy of any such amendment, modification
or waiver.

         3.2 The Issuer shall not request the Dealer to place or purchase Notes
whenever there shall have occurred any change in the Issuer's condition
(financial or otherwise), operations or business prospects or any development or
occurrence in relation to the Issuer that would be material to potential holders
of the Notes (including any downgrading or receipt of any notice of intended or
potential downgrading or any review for potential change in the rating accorded
any of the Issuer's securities by any nationally recognized statistical rating
organization which has published a rating of the Notes).

         3.3 The Issuer shall from time to time furnish to a Dealer such
publicly available information as such Dealer may reasonably request, including,
without limitation, any press releases or material provided by the Issuer to any
national securities exchange or rating agency, regarding (i) the Issuer's
operations and financial condition, (ii) the due authorization and execution of
the Notes and (iii) the Issuer's ability to pay the Notes as they mature.

         3.4 The Issuer will take all such action as the Dealer may reasonably
request to ensure that each offer and each sale of the Notes will comply with
any applicable state Blue Sky laws; provided, however, that the Issuer shall not
be obligated to file any general consent to service of process or to qualify as
a foreign corporation in any jurisdiction in which it is not so qualified or
subject itself to taxation in respect of doing business in any jurisdiction in
which it is not otherwise so subject.
<PAGE>   8
         3.5 The Issuer shall not issue Notes hereunder until the Dealer shall
have received (a) an opinion of counsel to the Issuer, addressed to the Dealer,
satisfactory in form and substance to the Dealer, (b) a copy of the executed
Issuing and Paying Agency Agreement as then in effect, (c) a copy of resolutions
adopted by the Board of Directors of the Issuer, satisfactory in form and
substance to the Dealer and certified by the Secretary or similar officer of the
Issuer, authorizing execution and delivery by the Issuer of this Agreement, the
Issuing and Paying Agency Agreement and the Notes and consummation by the Issuer
of the transactions contemplated hereby and thereby, (d) prior to the issuance
of any Notes represented by a book-entry note registered in the name of DTC or
its nominee, a copy of the executed Letter of Representations among the Issuer,
the Issuing and Paying Agent and DTC and (e) such other certificates, opinions,
letters and documents as the Dealer shall have reasonably requested.

         3.6 The Issuer shall reimburse the Dealer for all of the Dealer's
out-of-pocket expenses related to this Agreement, including expenses incurred in
connection with its preparation and negotiation, and the transactions
contemplated hereby (including, but not limited to, the printing and
distribution of the Private Placement Memorandum), and, if applicable, for the
reasonable fees and out-of-pocket expenses of the Dealer's counsel.

4.       DISCLOSURE

         4.1 The Private Placement Memorandum and its contents (other than the
Dealer Information) shall be the sole responsibility of the Issuer. The Private
Placement Memorandum shall contain a statement expressly offering an opportunity
for each prospective purchaser to ask questions of, and receive answers from,
the Issuer concerning the offering of Notes and to obtain relevant additional
information which the Issuer possesses or can acquire without unreasonable
effort or expense.

         4.2 The Issuer agrees to promptly furnish the Dealer the Company
Information as it becomes publicly available.

         4.3 At any time that the Issuer has directed a Dealer to purchase Notes
from the Issuer and place such Notes in inventory, and such Dealer has done so
and continues to hold such Notes in its inventory, then the Issuer agrees:

                  (a) to notify such Dealer promptly upon the occurrence of any
event (but not as to the substance of any such event) relating to or affecting
the Issuer that would cause the Company Information then in existence to include
an untrue statement of a material fact or to omit to state a material fact
necessary in order to make the statements contained therein, in light of the
circumstances under which they are made, not misleading; the provision of such
notification will be held in confidence by such Dealer, provided that the Issuer
shall not be able to issue Notes pursuant to this Agreement until such time as
the Issuer has supplemented or amended the Company Information so that the
Company Information, as amended or supplemented, shall not contain an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading.
<PAGE>   9
                  (b) (i) promptly to supplement or amend the Company
Information so that the Company Information, as amended or supplemented, shall
not contain an untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and the Issuer shall
make such supplement or amendment available to such Dealer; or (ii) the Issuer
shall purchase from such Dealer any such Notes at a price equal to: (a) the
principal amount thereof plus accrued and unpaid interest thereon, in the case
of an interest-bearing Note, or (b) the face amount thereof discounted on a
ratable basis based on the Issuer's market rate reflecting the remaining period
until maturity in relation to the original term, in the case of such Note issued
on a discount basis, provided that no commissions or fees will be paid to such
Dealer in connection with any such repurchase pursuant to this Section
4.3(b)(ii).

5.       INDEMNIFICATION AND CONTRIBUTION

         5.1 The Issuer agrees to assume liability for and indemnify, protect
and hold harmless the Dealer, each individual, corporation, partnership, trust,
association or other entity ("Person") controlling the Dealer, and their
respective directors, officers, incorporators, shareholders, partners, servants,
trustees, employees and agents (all of such indemnified entities hereinafter
"Indemnitees" or, if the context requires, "indemnified parties") from and
against any and all losses, liabilities, claims, damages, penalties, causes of
action, suits, costs and expenses (including, without limitation, reasonable
attorneys' fees and expenses) or judgments of whatever kind and nature, imposed
upon, incurred by or asserted against the Indemnitees, which are (x) based on or
arising under the securities laws of the United States of America or of any
state or of any regulation, rule or interpretation thereunder or thereof to the
extent arising from the transactions contemplated hereby except as may otherwise
be limited herein, (y) based upon the inaccuracy of any representation made or
reaffirmed by the Issuer, or the breach of any agreement or covenant of the
Issuer contained herein, or (z) based upon any untrue statement or alleged
untrue statement of a material fact or the omission or alleged omission
therefrom of a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading.

                  It is agreed, however, that the obligations of the Issuer
under this indemnification shall not extend to any liability of any Indemnitee
arising out of (i) any untrue statement or alleged untrue statement of a
material fact contained in the Private Placement Memorandum, or the omission or
alleged omission to state therein a material fact necessary to make the
statements therein not misleading, in each case, to the extent such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information relating to a Dealer
in its capacity as agent for the sale of the Notes or a Dealer's activities
pursuant to this Agreement furnished to the Issuer by or on behalf of the Dealer
specifically for use in connection with the preparation of the Private Placement
Memorandum or (ii) the Dealer's willful misconduct or gross negligence in the
performance of its obligations under this Agreement or to any liability arising
out of a material breach by a Dealer of its obligations under this Agreement.
<PAGE>   10
         5.2 The Dealer agrees to indemnify and hold harmless the Issuer, its
directors, its officers, and each person who controls the Issuer within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act""
(all such indemnified entities hereinafter the "Issuer Indemnitees" or, if the
context requires, the "indemnified parties") against any and all losses,
liabilities, claims, damages, penalties, causes of action, suits, costs and
expenses (including, without limitation, reasonable attorneys' fees and
expenses) to which the Issuer or Issuer Indemnitees may become subject under the
Securities Act, the Exchange Act or other Federal or state statutory law or
regulation, insofar as such losses, liabilities, claims, damages, penalties,
causes of action, suits, costs or expenses arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in the
Private Placement Memorandum, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, but only with
reference to written information relating to the Dealer in their capacity as
agents for the sale of the Notes or the Dealer's activities pursuant to this
Agreement furnished to the Issuer by or on behalf of the Dealer specifically for
use in connection with the preparation of the Private Placement Memorandum.

         5.3 The Issuer and the Dealer agree that upon the commencement of any
action against any Issuer Indemnitee or any Indemnitee in respect of which
indemnity may be sought on account of any indemnity agreement contained herein,
it 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 reasonably
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 the
Issuer, in the case of the Issuer Indemnitees, and the applicable Dealer, in the
case of the Indemnitees. 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, which consent shall not be unreasonably withheld or
delayed.

         5.4 The foregoing indemnities will also extend to any supplemental
material subsequently furnished to (i) the Dealer by the Issuer or (ii) the
Issuer by a Dealer and distributed to purchasers or prospective purchasers
during the term of this Agreement.

         5.5 In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section is for
any reason held unavailable (other than in accordance with the terms of this
section), the Issuer or the Dealer, as the case may be, on the one hand, and any
Indemnitees or Issuer Indemnitees, as the case may be, on the other hand, sought
to be charged with any liability shall contribute to the aggregate costs of
satisfying such liability in such proportion as is appropriate to reflect (i)
the relative benefits received by the Issuer on the one hand and the Dealer on
the other from the offering of the Notes and (ii) the relative fault of the
Issuer on the one hand and the Dealer on the other in connection with the
actions, inactions, statements or omissions which resulted in such losses,
liabilities, claims, damages, penalties, costs and expenses, as well as any
other relevant equitable considerations. The relative benefits received by the
Issuer, on the one hand, and the Dealer, on the other hand, in connection with
the offering of the Notes (before deducting expenses) received by the Issuer
bear to the total commission and other compensation received by the Dealer in
respect thereof. The relative fault of the Dealer, on the one hand, and the
Issuer, on the other and, shall be determined by reference to, among other
things, (i) in the case of actions or inactions, the party responsible for such
actions or inactions, the parties' relative intent and the opportunity of the
parties to prevent or take corrective measures with respect to such actions or
inactions, and (ii) in the case of an untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact,
whether such untrue statement or omission or alleged untrue statement or
omission relates to information supplied by the Dealer or the Issuer and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Issuer, on the one hand, and
the Dealer, on the other hand, agree that it would not be just and equitable if
contribution pursuant to this Section 5.5 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above. For purposes of this Section 5.5,
each Indemnitee shall have the same rights to contribution as the Dealer and
each Issuer Indemnitee shall have the same rights to contribution as the Issuer.
Any party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties
under this Section 5.5, notify such party or parties from whom contribution may
be sought, but the omission to so notify such party or parties shall
<PAGE>   12
not relieve the party or parties from whom contribution may be sought from any
obligation it or they may have hereunder or otherwise than under this Section
5.5.

         5.6 The obligations of the Issuer under this Section 5 shall survive
any termination of this Agreement, in whole or in part.
