ALLIANT  ENERGY  RESOURCES   COMPLETES  $402.5  MILLION  PRIVATE   PLACEMENT  OF
EXCHANGEABLE SENIOR NOTES

         MADISON,  WIS.  --  February  1,  2000 --  Alliant  Energy  Corporation
(NYSE:LNT)  today  announced that its  wholly-owned  subsidiary,  Alliant Energy
Resources,  Inc., completed a private placement of 5,940,960 exchangeable senior
notes in accordance with Rule 144A under the Securities Act of 1933.

         The  exchangeable  senior notes were issued in the  original  aggregate
principal  amount of $402.5 million,  and will be due in 2030. The  exchangeable
senior notes have an interest rate of 7.25 percent through February 15, 2003 and
2.5 percent thereafter.  The exchangeable senior notes are exchangeable for cash
based upon the value of McLeodUSA  Incorporated  Class A Common  Stock.  Alliant
Energy Corporation has agreed to fully and unconditionally guarantee the payment
of principal and interest on the exchangeable senior notes.

         Alliant Energy Resources  expects to use the net proceeds from the sale
of the  exchangeable  senior notes (1) to repay  commercial paper Alliant Energy
Resources   issued    initially   to   capitalize   its   wholly-owned    exempt
telecommunications  company  and  indirectly,  through an  internal  transfer of
assets, to fund Alliant Energy Resources recent investment in Brazil and (2) for
general  corporate  purposes,  including  to fund  potential  future  investment
opportunities in energy  marketing,  co-generation,  environmental  services and
other areas.  Alliant Energy Resources may initially invest net proceeds that it
does not immediately require in short-term marketable securities.

         The  exchangeable  senior  notes  have not been  registered  under  the
Securities Act of 1933 and may not be offered or sold absent  registration under
such Act or an applicable exemption from the registration requirements.

Ladies and Gentlemen:

         Alliant  Energy   Resources,   Inc.,  a  Wisconsin   corporation   (the
"Company"),  and  Alliant  Energy  Corporation,  a  Wisconsin  corporation  (the
"Parent"),  confirm their  agreement  with Merrill Lynch & Co.,  Merrill  Lynch,

with  respect  to the  issue and sale by the  Company  and the  purchase  by the
Initial  Purchaser  of  5,166,052   Exchangeable  Senior  Notes  due  2030  (the

purchased by the Initial  Purchaser and all or any part of the PHONES subject to
the option  described  in section  2(b) hereof  (the  "Option  Securities")  are

guaranteed  as to payment of  principal,  premium,  if any,  and interest by the
Parent and will be issued  pursuant to an indenture dated as of November 4, 1999
(the  "Indenture")  between the Company,  the Parent and Firstar Bank,  N.A., as

<PAGE>

Trust  Company  ("DTC")  pursuant to a letter  agreement,  to be dated as of the
Closing  Time (as  defined in Section  2(b))  (the "DTC  Agreement"),  among the
Company, the Trustee and DTC.

         The Company  understands that the Initial Purchaser proposes to make an
offering of the  Securities  on the terms and in the manner set forth herein and
agrees that the Initial  Purchaser  may resell,  subject to the  conditions  set
forth herein,  all or a portion of the  Securities  to  purchasers  ("Subsequent
Purchasers")  at any time after this  Agreement has been executed and delivered.
The Securities are to be offered and sold through the Initial  Purchaser without
being  registered under the Securities Act of 1933, as amended (the "1933 Act"),
in reliance upon exemptions  therefrom.  Pursuant to the terms of the Securities
and the  Indenture,  investors  that  acquire  Securities  may  only  resell  or
otherwise  transfer such Securities if such Securities are hereafter  registered
under the 1933 Act or if an exemption from the registration  requirements of the
1933 Act is  available  (including  the  exemption  afforded by Rule 144A ("Rule
144A")  of the  rules  and  regulations  promulgated  under  the 1933 Act by the
Securities and Exchange  Commission (the  "Commission")  and the exemption under
Regulation D  ("Regulation  D") for sales to a limited  number of  institutional
"accredited  investors" as that term is defined in Rule  501(a)(1),  (2), (3) or
(7) under the Securities Act (each, an "Institutional Accredited Investor")).

         Holders (including subsequent  transferees) of the Securities will have

"Registration  Rights Agreement"),  to be entered at the Closing Time, among the
Company,  the Parent and the Initial  Purchaser,  for so long as such Securities
constitute  "Registrable  Securities"  (as  defined in the  Registration  Rights
Agreement).  Pursuant to the Registration Rights Agreement,  the Company and the
Parent will use their  reasonable best efforts to file with the Commission under
the circumstances set forth therein, (i) a registration statement under the 1933
Act (the "Exchange Offer  Registration  Statement")  registering an issue of the
Company's  PHONES  identical in all  material  respects to the  Securities  (the
"Exchange  Securities")  to be  offered  in  exchange  for the  Securities  (the
"Exchange  Offer")  and  (ii),  under  certain  circumstances,   a  registration
statement  pursuant  to Rule 415  under  the 1933 Act (the  "Shelf  Registration
Statement") to register the Securities.

         The Company has prepared and delivered to the Initial  Purchaser copies
of a preliminary  offering  memorandum dated January 26, 2000 (the  "Preliminary
Offering  Memorandum")  and  has  prepared  and  will  deliver  to  the  Initial
Purchaser,  on the date  hereof or the next  succeeding  day,  copies of a final
offering  memorandum  dated January 26, 2000 (the "Final Offering  Memorandum"),

<PAGE>

Purchaser as evidenced by a notice in writing from the Initial  Purchaser to the

the Parent and their respective  subsidiaries,  taken as a whole, which (i) make
any statement in the Offering Memorandum  materially false or misleading or (ii)

circumstances then existing,  the Company will forthwith amend or supplement the
Final Offering  Memorandum by preparing and furnishing to the Initial  Purchaser
an amendment or  amendments  of, or a supplement  or  supplements  to, the Final
Offering  Memorandum  (in  form and  substance  satisfactory  in the  reasonable
opinion  of  counsel  for the  Initial  Purchaser)  so that,  as so  amended  or
supplemented, the Final Offering Memorandum will not include an untrue statement
of a material fact or omit to state a material  fact  necessary in order to make
the statements therein,  in the light of the circumstances  existing at the time
it is delivered to a Subsequent Purchaser, not misleading.

         (c) Amendment to Offering  Memorandum and Supplements.  The Company and
the Parent will advise the Initial  Purchaser  promptly of any proposal to amend
or  supplement  the Offering  Memorandum  and will not effect such  amendment or
supplement without the consent of the Initial Purchaser, which consent shall not
be unreasonably withheld.  Neither the consent of the Initial Purchaser, nor the
Initial  Purchaser's  delivery  of  any  such  amendment  or  supplement,  shall
constitute a waiver of any of the conditions set forth in Section 5 hereof.  The
Company will furnish to the Initial  Purchaser,  without charge,  such number of
copies of such  amendment or supplement as the Initial  Purchaser may reasonably
request.

use its best efforts, in cooperation with the Initial Purchaser,  to qualify the
Securities  for offering and sale under the applicable  securities  laws of such
states and other  jurisdictions as the Initial  Purchaser may designate and will
maintain such  qualifications  in effect as long as required for the sale of the
Securities;  provided,  however, that the Company shall not be obligated to file
any general consent to service of process or to qualify as a foreign corporation
or as a dealer in securities in any jurisdiction in which it is not so qualified

         (f) DTC. The Company will cooperate with the Initial  Purchaser and use

         limited  number  of  persons  who are  other  institutional  accredited
         investors,  as such term is defined in Rule 501(a)(1),  (2), (3) or (7)

                (ii) No General Solicitation. No general solicitation or general
         advertising (within the meaning of Rule 502(c) under the 1933 Act) will

         Securities from the Initial Purchaser or affiliate, as the case may be,
         in the United States that the Securities (A) have not been and will not
         be  registered  under the 1933 Act,  (B) are being sold to them without
         registration  under  the  1933  Act in  reliance  on  Rule  144A  or in
         accordance with another exemption from registration under the 1933 Act,
         as the  case  may be,  and (C) may not be  offered,  sold or  otherwise
         transferred  except (1) to the Company or (2) inside the United  States
         in accordance with (x) Rule 144A to a person whom the seller reasonably
         believes is a Qualified  Institutional  Buyer that is  purchasing  such
         Securities  for  its own  account  or for the  account  of a  Qualified
         Institutional  Buyer to whom  notice is given that the  offer,  sale or
         transfer  is being made in  reliance  on Rule 144A or (y)  pursuant  to
         another available exemption from registration under the 1933 Act.

Parent, jointly and severally, covenant with the Initial Purchaser as follows:

                 (i)  Integration.  The Company  and the Parent  agree that they
         will not and will cause their respective Affiliates not to, directly or
         indirectly,  solicit  any offer to buy,  sell or make any offer or sale
         of, or otherwise  negotiate in respect of, securities of the Company of
         any class if, as a result of the doctrine of "integration"  referred to
         in Rule 502 under the 1933 Act, such offer or sale would render invalid
         (for the  purpose of (i) the sale of the  Securities  by the Company to
         the Initial Purchaser, (ii) the resale of the Securities by the Initial
         Purchaser  to  Subsequent   Purchasers  or  (iii)  the  resale  of  the
         Securities by such Subsequent  Purchasers to others) the exemption from
         the registration  requirements of the 1933 Act provided by Section 4(2)
         thereof or by Rule 144A thereunder or otherwise.

                (ii) Rule 144A  Information.  The Company  and the Parent  agree
         that, in order to render the Securities eligible for resale pursuant to
         Rule  144A  under  the 1933 Act,  while  any of the  Securities  remain
         outstanding,  they will make available,  upon request, to any holder of
         Securities or  prospective  purchasers of  Securities  the  information
         specified in Rule  144A(d)(4),  unless such information is furnished to
         the Commission pursuant to Section 13 or 15(d) of the 1934 Act.

               (iii)  Restriction  on  Repurchases.  Until the expiration of two
         years after the original  issuance of the  Securities,  the Company and
         the Parent will not, and will cause their respective Affiliates not to,
         resell any Securities  which are "restricted  securities" (as such term
         is  defined  under  Rule  144(a)(3)  under the 1933  Act),  whether  as
         beneficial  owner or otherwise  (except as agent acting as a securities
         broker on behalf of and for the account of  customers  in the  ordinary
         course of business in unsolicited broker's transactions).

         (c) Qualified Institutional Buyer. The Initial Purchaser represents and
warrants to, and agrees with,  the Company and the Parent that it is a Qualified
Institutional  Buyer  within the  meaning of Rule 144A under the 1933 Act and an
"accredited  investor"  within the meaning of Rule 501(a) under the 1933 Act (an
"Accredited Investor").

jointly  and  severally,  agree to  indemnify  and  hold  harmless  the  Initial
Purchaser and each person, if any,

         Preliminary  Offering  Memorandum or the Final Offering  Memorandum (or
         any  amendment  or  supplement  thereto),  or the  omission  or alleged
         omission  therefrom of a material  fact  necessary in order to make the
         statements  therein, in the light of the circumstances under which they
         were made, not misleading;

                (ii)  against  any and all loss,  liability,  claim,  damage and
         expense whatsoever,  as incurred, to the extent of the aggregate amount
         paid  in  settlement  of  any  litigation,   or  any  investigation  or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim  whatsoever  based upon any such  untrue  statement  or
         omission,  or any such alleged untrue  statement or omission;  provided
         that  (subject to Section 7(d) below) any such  settlement  is effected
         with the written consent of the Company and the Parent; and

               (iii)  against  any  and  all  expense  whatsoever,  as  incurred
         (including  the fees and  disbursements  of  counsel  chosen by Merrill
         Lynch),  reasonably  incurred in investigating,  preparing or defending
         against any  litigation,  or any  investigation  or  proceeding  by any
         governmental  agency or body,  commenced  or  threatened,  or any claim
         whatsoever  based upon any such untrue  statement or  omission,  or any
         such alleged untrue statement or omission,  to the extent that any such
         expense is not paid under (i) or (ii) above;

provided,  however,  that this indemnity  agreement shall not apply to any loss,
liability,  claim,  damage or expense to the  extent  arising  out of any untrue
statement or omission or alleged  untrue  statement or omission made in reliance
upon and in conformity with written information  furnished to the Company or the
Parent,  as the case may be, by any Initial  Purchaser  expressly for use in the
Offering Memorandum (or any amendment thereto).

         (b) Indemnification of Company and Parent. The Initial Purchaser agrees
to indemnify  and hold  harmless the Company and the Parent and each person,  if
any, who controls the Company or the Parent  within the meaning of Section 15 of
the 1933 Act or Section 20 of the 1934 Act against any and all loss,  liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this  Section,  as incurred,  but only with respect to untrue  statements  or
omissions,  or alleged  untrue  statements  or  omissions,  made in the Offering
Memorandum in reliance upon and in conformity with written information furnished
to the  Company  or the  Parent,  as the case may be, by the  Initial  Purchaser
expressly for use in the Offering Memorandum.

         (c) Actions against Parties; Notification. Each indemnified party shall
give notice as promptly as reasonably  practicable to each indemnifying party of
any action  commenced  against it in  respect of which  indemnity  may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying  party  from  any  liability  hereunder  to  the  extent  it is not
materially  prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In the case of parties  indemnified  pursuant to Section 7(a) above,
counsel to the indemnified  parties shall be selected by Merrill Lynch,  and, in
the case of parties indemnified  pursuant to Section 7(b) above,  counsel to the
indemnified  parties shall be selected by the Parent. An indemnifying  party may
participate  at its own  expense in the  defense of any such  action;  provided,
however,  that  counsel to the  indemnifying  party shall not  (except  with the
consent of the indemnified  party) also be counsel to the indemnified  party. In
no event shall the indemnifying  parties be liable for fees and expenses of more
than one counsel  (in  addition to any local  counsel)  separate  from their own
counsel  for all  indemnified  parties  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.  In addition,  the indemnifying
party shall be entitled to, to the extent that it wishes, jointly with any other
similarly  notified  indemnifying  party,  to assume the defense of any claim or
action brought against an indemnified party with counsel reasonably satisfactory
to the  indemnified  party.  After  notice  from the  indemnifying  party to the
indemnified party of its election to assume the defense of such claim or action,
the indemnifying  party shall not be liable to the indemnified  party under this
Section  7 for  any  legal  or  other  expenses  subsequently  incurred  by  the
indemnified  party in connection  with the defense thereof other than reasonable
costs of investigation; provided, however, that the Initial Purchaser shall have
the right to employ one counsel to represent it and its officers,  employees and
controlling  persons who may be subject to liability arising out of any claim in
respect of which  indemnity may be sought by the Initial  Purchaser  against the
Company and the Parent  under this Section 7 if, in the  reasonable  judgment of
the  Initial  Purchaser,  either  (i) there is an actual or  potential  conflict
between  the  position  of the  Company  and the  Parent on the one hand and the
Initial  Purchaser on the other hand or (ii) there may be defenses  available to
it or them that are  different  from or  additional  to those  available  to the
Company and Parent (in any of which events the Company  shall not have the right
to direct the  defense of such action on behalf of the  Initial  Purchaser  with
respect to such different defenses), in any of which events such reasonable fees
and expenses  shall be borne by the Company and Parent.  No  indemnifying  party
shall, without the prior written consent of the indemnified  parties,  settle or
compromise  or  consent  to  the  entry  of any  judgment  with  respect  to any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  in respect of which
indemnification  or contribution could be sought under this Section or Section 8
hereof (whether or not the indemnified  parties are actual or potential  parties
thereto),  unless  such  settlement,  compromise  or  consent  (i)  includes  an
unconditional  release of each indemnified  party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as


                                       24

<PAGE>

to or an admission of fault,  culpability or a failure to act by or on behalf of
any indemnified party.

         (d) Settlement without Consent if Failure to Reimburse.  If at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified  party for fees and  expenses of counsel,  such  indemnifying  party
agrees that it shall be liable for any settlement of the nature  contemplated by
Section 7(a)(ii)  effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such  indemnifying  party of the
aforesaid  request,  (ii) such indemnifying  party shall have received notice of
the terms of such  settlement  at least 30 days prior to such  settlement  being
entered into and (iii) such  indemnifying  party shall not have  reimbursed such
indemnified  party in  accordance  with such  request  prior to the date of such
settlement.

         SECTION 8. Contribution. If the indemnification provided for in Section
7 hereof is for any reason  unavailable to or  insufficient  to hold harmless an
indemnified  party in respect of any  losses,  liabilities,  claims,  damages or
expenses referred to therein,  then each indemnifying  party shall contribute to
the aggregate amount of such losses,  liabilities,  claims, damages and expenses
incurred by such  indemnified  party, as incurred,  (i) in such proportion as is
appropriate  to reflect the  relative  benefits  received by the Company and the
Parent on the one hand and the  Initial  Purchaser  on the  other  hand from the
offering of the Securities  pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative  benefits  referred to in clause
(i) above but also the  relative  fault of the Company and the Parent on the one
hand and of the  Initial  Purchaser  on the other  hand in  connection  with the
statements  or omissions  which  resulted in such losses,  liabilities,  claims,
damages or expenses, as well as any other relevant equitable considerations.

         The relative benefits received by the Company and the Parent on the one
hand and the Initial Purchaser on the other hand in connection with the offering
of the Securities  pursuant to this Agreement  shall be deemed to be in the same
respective  proportions  as the  total net  proceeds  from the  offering  of the
Securities  pursuant to this Agreement (before deducting  expenses)  received by
the  Company  and  the  total  underwriting  discount  received  by the  Initial
Purchaser, bear to the aggregate initial offering price of the Securities.

         The  relative  fault of the  Company and the Parent on the one hand and
the Initial  Purchaser on the other hand shall be  determined  by reference  to,
among other  things,  whether any such untrue or alleged  untrue  statement of a
material  fact or omission or alleged  omission to state a material fact relates
to  information  supplied  by the  Company  and  the  Parent  or by the  Initial
Purchaser and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.


                                       25
<PAGE>

         The Company,  the Parent and the Initial  Purchaser agree that it would
not be  just  and  equitable  if  contribution  pursuant  to this  Section  were
determined by pro rata allocation (even if the Initial Purchaser 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 Section.
The  aggregate  amount of losses,  liabilities,  claims,  damages  and  expenses
incurred by an indemnified  party and referred to above in this Section shall be
deemed  to  include  any legal or other  expenses  reasonably  incurred  by such
indemnified  party  in   investigating,   preparing  or  defending  against  any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  based upon any such
untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding  the provisions of this Section,  the Initial Purchaser
shall not be required to contribute  any amount in excess of the amount by which
the  total  price at which the  Securities  purchased  and sold by it  hereunder
exceeds the amount of any damages which the Initial Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this  Section,  each  person,  if any, who controls the
Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act  shall  have the same  rights  to  contribution  as the  Initial
Purchaser,  and each  person,  if any,  who  controls  the Company or the Parent
within  the  meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
shall have the same rights to contribution as the Company and the Parent.

         SECTION  9.  Representations,  Warranties  and  Agreements  to  Survive
Delivery.  All  representations,  warranties  and  agreements  contained in this
Agreement or in  certificates  of officers of the Company,  the Parent or any of
their respective  subsidiaries  submitted pursuant hereto shall remain operative
and in full force and  effect,  regardless  of any  investigation  made by or on
behalf of the Initial Purchaser or controlling person, or by or on behalf of the
Company or the  Parent,  and shall  survive  delivery of the  Securities  to the
Initial Purchaser.

         SECTION 10.  Termination of Agreement.

         (a)  Termination;  General.  The Initial  Purchaser may terminate  this
Agreement,  by notice to the Company and the Parent,  at any time at or prior to
the  Closing  Time (i) if there has been,  since the time of  execution  of this
Agreement or since the respective dates as of which  information is given in the
Offering Memorandum, any material adverse change in the condition,  financial or
otherwise,  or in the earnings or business affairs of the Company and the Parent
and


                                       26
<PAGE>

their  respective  subsidiaries,  in each case,  considered  as one  enterprise,
whether or not arising in the ordinary  course of  business,  nor has there been
any developments  involving a prospective material adverse change of the Company
and the Parent and their respective  subsidiaries,  in each case,  considered as
one enterprise,  whether or not arising in the ordinary course of business, (ii)
if there has occurred any material  adverse  change in the financial  markets in
the United  States or the  international  financial  markets,  any  outbreak  of
hostilities  or escalation  thereof or other calamity or crisis or any change or
development   involving  a  prospective  change  in  national  or  international
political, financial or economic conditions, in each case the effect of which is
such as to  make  it,  in the  reasonable  judgment  of the  Initial  Purchaser,
impracticable  to market the Securities or to enforce  contracts for the sale of
the Securities, (iii) if trading in any securities of the Company or the Parent,
or in McLeod Shares, has been suspended or materially limited by the Commission,
the New York Stock  Exchange or The Nasdaq Stock Market,  as the case may be, or
if  trading  generally  on the  American  Stock  Exchange  or the New York Stock
Exchange or in the NASDAQ System has been  suspended or materially  limited,  or
minimum or maximum  prices for trading  have been fixed,  or maximum  ranges for
prices  have been  required,  by any of said  exchanges  or by such system or by
order of the Commission, the National Association of Securities Dealers, Inc. or
any  other  governmental  authority  or (iv) if a  banking  moratorium  has been
declared by either Federal or New York authorities.

         (b)  Liabilities.  If this  Agreement  is  terminated  pursuant to this
Section,  such termination  shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 7, 8 and 9 shall  survive  such  termination  and  remain  in full  force and
effect.

         SECTION 11. Default by the Initial Purchaser.  If the Initial Purchaser
shall fail at the Closing Time or the Date of  Delivery,  as the case may be, to
purchase the  Securities  which it is obligated to purchase under this Agreement
(the "Defaulted Securities"), this Agreement shall terminate.

         The  termination  of this  Agreement due to such default by the Initial
Purchaser  shall not relieve the Initial  Purchaser from liability in respect of
its default.

         SECTION 12.  Notices.  All notices and other  communications  hereunder
shall be in  writing  and shall be  deemed to have been duly  given if mailed or
transmitted  by any standard form of  telecommunication.  Notices to the Initial
Purchaser  shall be directed  to the Initial  Purchaser  at North  Tower,  World
Financial  Center,  New  York,  New York  10281,  attention  of John  Thorndike,
Managing  Director,  notices to the  Company  shall be  directed  to it 222 West

         SECTION 13.  Parties.  This Agreement shall inure to the benefit of and
be  binding  upon the  Initial  Purchaser,  the  Company,  the  Parent and their
respective  successors.  Nothing  expressed or  mentioned  in this  Agreement is

than the  Initial  Purchaser,  the  Company,  the  Parent  and their  respective
successors and the controlling persons and officers and directors referred to in
Sections  7 and 8 and  their  heirs  and  legal  representatives,  any  legal or
equitable  right,  remedy or claim under or in respect of this  Agreement or any
provision  herein  contained.  This  Agreement and all conditions and provisions
hereof are  intended  to be for the sole and  exclusive  benefit of the  Initial
Purchaser,  the Company,  the Parent and their respective  successors,  and said
controlling  persons  and  officers  and  directors  and  their  heirs and legal
representatives, and for the benefit of no other person, firm or corporation. No
purchaser  of  Securities  from the  Initial  Purchaser  shall be deemed to be a
successor by reason merely of such purchase.

         SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY
AND  CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK.  EXCEPT AS
OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

               The Company and the Guarantor  desire to supplement and amend the
Indenture to allow for the issuance of  Securities  to be initially  sold within
the United States to U.S.  Persons that are Qualified  Institutional  Buyers and
Institutional  Accredited  Investors  and  issued  in the  form  of one or  more
Restricted  Global Securities  deposited with the Trustee,  as custodian for the
Depositary,  and  registered  in the name of a nominee  of the  Depositary,  and
Restricted Physical Securities.

               The Company and the  Guarantor  desire to set forth the terms and
form of a new  series  of  Restricted  Securities  to be known as the  Company's
Exchangeable Senior Notes due 2030 (the "PAY PHONES" or the "PHONES"), which are
exchangeable  for cash based on the value of  McLeodUSA  Incorporated's  Class A
Common Stock,  initially  limited to an aggregate number of 5,166,052 PHONES (or
up to 5,940,960 if additional  PHONES are issued in connection with the exercise
by the  Initial  Purchaser  (as such term is defined in the  Purchase  Agreement
dated  January  26,  2000  among the  Company,  the  Guarantor  and the  Initial
Purchaser  named  therein) of its  over-allotment  option)  and  unconditionally
guaranteed by the Guarantor.

               The  PHONES,   the  related  guarantee  and  the  certificate  of
authentication to be borne by the PHONES are to be substantially in the form set
forth in Exhibit A hereto.

any  property,   including  cash  (other  than  any  regular  cash   dividends),
distributed  on or with respect to the  Reference  Shares  (other than  publicly
traded  equity  securities,  which will  themselves  become  Reference  Shares).
Interest on the PHONES  shall be paid  quarterly  in arrears on February 15, May
15,  August 15 and November 15 of each year,  beginning May 15, 2000, to holders
of record at the close of business  on February 1, May 1, August 1 and  November
1, as the case may be, immediately  preceding the payment date (whether or not a
business day), but subject to the Company's right to defer quarterly payments of
basic interest beginning after the February 15, 2003 payment.

the case  may be,  by check  mailed  to the  registered  address  of the  person
entitled  thereto as such  address  shall  appear on the  registry  books of the
Company.  On each interest  payment date the Trustee shall pay to the registered
holder  interest  accrued in respect of such  PHONES.  Payment of  principal  on
PHONES  shall be paid to the  registered  holder  or upon his  order  only  upon
presentation  and  surrender  for payment of such PHONES on or after the payment
date at the  offices  of the  Company or the  Guarantor,  as the case may be, in
Milwaukee,  Wisconsin  and the Borough of Manhattan,  The City of New York,  New
York or at any other office of the Company or the Guarantor, as the case may be,
maintained for such purpose.

               (c) The PHONES shall not be convertible  into or exchangeable for
equity securities of the Company, the Guarantor or McLeodUSA Incorporated.

               (d) The PHONES shall not be subject to any sinking fund.

               (e) The Trustee,  at its Corporate  Trust Office  located at 1555

registered  owner of any  Restricted  Global  Security,  such  nominee  shall be
considered  the  sole  owner  and  holder  of the  PHONES  represented  by  such
Restricted  Global  Security under the Indenture,  as  supplemented  and amended
hereby.  Except  as  herein  provided,  owners of  beneficial  interests  in any
Restricted  Global Security shall not be entitled to have PHONES  represented by
such Restricted Global Security  registered in their names, shall not receive or
be entitled to receive  physical  delivery  of PHONES in  certificated  form and
shall not be considered the owners or holders thereof under the Indenture.

               (b) None of the Company,  the Guarantor or the Trustee shall have
any  responsibility  or liability  for any aspect of the records  relating to or
payments made on account of  beneficial  ownership  interests in any  Restricted
Global  Security,  or for  maintaining,  supervising  or  reviewing  any records
relating to such beneficial interests.

Holders (by virtue of their  acceptance of the PHONES) shall treat the PHONES as
indebtedness  of the Company for all tax  purposes.  The  Company  shall  hereby
instruct the Trustee to treat the PHONES as  indebtedness of the Company for all
tax reporting purposes.  The Company, the Trustee and the Holders shall not take
any  position  that  is  inconsistent  with  the  treatment  of  the  PHONES  as
indebtedness of the Company for all tax purposes.


                                   ARTICLE 3.

                                  MISCELLANEOUS

have the  respective  meanings set forth in the Indenture and the form of PHONES
attached hereto as Exhibit A.

attached  hereto as Exhibit A,  constitute a part of the provisions with respect
to the PHONES and are incorporated  into this Second  Supplemental  Indenture in
its  entirety  and shall for all  purposes  have the same effect as if fully set
forth in this Second Supplemental Indenture.

               Section 3.03.  Except as  supplemented  and amended  hereby,  the
Indenture as supplemented and amended by the First Supplemental  Indenture is in

enforceability  of the remaining  provisions shall not in any way be affected or
impaired thereby.

Indenture  limits,  qualifies or conflicts with any other provision hereof or of
the Indenture which provision is required to be included in the Indenture by any
of the  provisions of the Trust  Indenture  Act, such required  provision  shall
control.

               Section  3.06.  THIS  SECOND  SUPPLEMENTAL   INDENTURE  SHALL  BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF WISCONSIN

simultaneously  executed in several counterparts,  each of which shall be deemed

to have been executed on the date of the  acknowledgment  thereof by the officer
of the Trustee who signed it on behalf of the Trustee.

to be issued under the Indenture. Terms defined in the Indenture and not defined
herein have the meaning  ascribed  thereto in the Indenture.  The Securities are
subject to all such  terms,  and Holders are  referred  to the  Indenture  for a
statement of those terms.  As provided in the  Indenture,  the Securities may be
issued in one or more series,  which  different  series may be issued in various
aggregate  principal  amounts,  may be denominated in currencies other than U.S.
Dollars  (including  composite  currencies),  may mature at different times, may
bear  interest,  if  any,  at  different  rates,  may be  subject  to  different
redemption provisions, if any, may be subject to different sinking fund or other
purchase provisions, if any, may be subject to different covenants and Events of
Default and may otherwise vary as in the Indenture  provided or permitted.  This
PHONES is one of a series of the Securities  designated as  Exchangeable  Senior
Notes Due 2030,  which are exchangeable for cash based on the value of McLeodUSA
Incorporated's Class A Common Stock.

               The Maturity  Amount,  the Redemption  Amount (as defined below),
Additional  Interest  and Basic  Interest on the PHONES  shall be payable at the
office or agency the Company or the Guarantor, as the case may be, maintains for
such purpose within Milwaukee,  Wisconsin and the Borough of Manhattan, the City
of New York, New York, or at the Company's option, any such payments of cash may
be made by check  mailed  to the  Holders  of the  PHONES  at  their  respective
addresses  set forth in the  register of Holders of PHONES.  The PHONES shall be
issued in denominations of one PHONES and integral multiples thereof.

1.  Interest

               The Company  shall pay Basic  Interest on the Original  Principal
Amount  from the date of  original  issuance  or from the most  recent  Interest
Payment Date to which  interest has been paid or duly  provided for in an amount
equal to $1.2280 per PHONES,


                                       3
<PAGE>

reflecting a basic  interest  rate of 7.25% per annum on the Original  Principal
Amount,  through February 15, 2003, and thereafter in an amount equal to $0.4234
per PHONES,  reflecting a basic interest rate of 2.50% per annum on the Original
Principal Amount (as applicable,  the "Basic Interest Rate"),  in each case plus
the  amount  of  any  regular  cash  dividends  paid  on  the  Reference  Shares
attributable to each PHONES. Interest on the PHONES will accrue from the date of
issuance and will be paid quarterly in arrears on February 15, May 15, August 15
and November 15 of each year (each, an "Interest Payment Date" and collectively,
the "Interest  Payment Dates" and each quarterly  period ending on such Interest
Payment  Date, an "Interest  Payment  Period"),  beginning  May 15, 2000,  until
payment of the Maturity Amount,  or if redeemed  earlier,  the Redemption Amount
(as defined  below) or until  earlier  exchanged  upon  exercise of the Exchange
Right (as defined  below) by the Holder hereof.  The Company's  first payment of
Basic  Interest  on May 15,  2000  shall  equal  $1.4327  per  PHONES,  which is
calculated  to equal an annual rate of 7.25% on the  Original  Principal  Amount
from the date hereof.

               Basic  Interest  payable  on  any  Interest  Payment  Date  shall
(subject to exceptions  provided in the Indenture referred to herein) be paid to
the person in whose name this PHONES,  or the PHONES in exchange or substitution
for which this PHONES shall have been issued,  shall have been registered at the
close of  business on February 1, May 1, August 1 or November 1 (each a "Regular
Record Date"), as the case may be,  immediately  preceding such Interest Payment
Date whether or not a Business Day (as defined below). Changes in the Contingent
Principal  Amount  (as  defined  below)  shall not  affect  the  amount of Basic
Interest.  At least five (5) Business Days prior to each Interest  Payment Date,
the Company shall deliver an Officers' Certificate to the Trustee setting forth:
(i) the amount of Basic Interest per PHONES for such  quarterly  period and (ii)
the  total  quarterly  interest  due for such  quarterly  period  on all  PHONES
outstanding.

               The Company  shall also  distribute to the Holder of each PHONES,
an amount  equal to any  property,  including  cash (other than any regular cash
dividends),  distributed on or with respect to the Reference Shares attributable
to each PHONES  (other  than  publicly  traded  equity  securities,  which shall
themselves become Reference Shares) ("Additional  Interest").  If any Additional
Interest includes publicly traded securities (other than equity securities) that
can be transferred by the Company to the Holders without  registration under the
federal  securities laws and without breach of any  contractual  arrangements of
the Company with McLeodUSA Incorporated, and that will be freely transferable in
the hands of the Holders,  such securities shall be distributed to the Holder of
each PHONES; provided however, that no fractional units of such securities shall
be distributed, and the Company shall distribute cash representing the then fair
market value of such  fractional  units of such securities as determined in good
faith by the Board of  Directors.  If any  Additional  Interest is not  publicly
traded securities or is publicly


                                       4
<PAGE>

traded  securities not meeting the above standards,  cash  representing the then
fair market value of such property (as  determined in good faith by the Board of
Directors) shall be distributed to the Holder of each PHONES.

               Additional  Interest  shall be  distributed to the Holder of each
PHONES  on  the  twentieth  (20th)  Business  Day  (the   "Additional   Interest
Distribution  Date") after the Reference Shares  Distribution  Date.  "Reference
Shares  Distribution Date" means the date on which any property,  including cash
(other than any regular cash  dividends),  distributed on or with respect to the
Reference  Shares shall be distributed to the holders of Reference  Shares.  The
record  date for any  distribution  of  Additional  Interest  shall be the tenth
(10th) Business Day after the Reference Shares Distribution Date.

               At least five (5) Business Days prior to any Additional  Interest
Distribution  Date,  the Company shall deliver an Officers'  Certificate  to the
Trustee setting forth:  (i) the amount of Additional  Interest to be distributed
per PHONES;  and (ii) the total amount of Additional  Interest to be distributed
for all outstanding PHONES on such Additional Interest Distribution Date. If any
Additional  Interest  consists  of any  property  that  is not  publicly  traded
securities or is publicly traded securities not meeting the standards  described
above,  then at least five (5) Business Days prior to such  Additional  Interest
Distribution  Date,  the Company shall  deliver to the Trustee:  (i) a certified
copy of a Board Resolution  establishing the fair market value of such property;
and (ii) an  Officers'  Certificate  setting  forth (A) the total amount of cash
relating to the fair market value of such property to be distributed per PHONES,
and (B) the  total  amount of cash  relating  to the fair  market  value of such
property to be distributed  for all outstanding  PHONES.  In each case described
above,  the Company shall state in such Officers'  Certificate  whether it shall
distribute such Additional  Interest in property or cash. The Trustee shall only
be  responsible  for  distributing  Additional  Interest  in the form of cash or
global  book-entry  securities  which are DTC  eligible.  The  Company  shall be
responsible  for acting as its own paying agent to make all other  distributions
of Additional  Interest.  The Company shall prepare a press release  relating to
any  such  distribution  of  Additional  Interest  to be  provided  to  DTC  for
dissemination through the DTC broadcast facility.

               If Basic  Interest  or  Additional  Interest is payable on a date
that is not a Business Day,  payment shall be made on the next Business Day (and
without any  interest or other  payment in respect of such  delay).  A "Business
Day" means any day that is not a Saturday,  a Sunday or a legal holiday or a day
on which  banking  institutions  or trust  companies in The City of New York are
authorized or obligated by law to close.

               The  Company  shall  pay  interest  at a rate  equal to the Basic
Interest Rate per annum then in effect on (i) any overdue Maturity Amount;  (ii)
any overdue  installments of Basic Interest;  and (iii) any overdue  payments of
Additional Interest based


                                       5
<PAGE>

on the fair market  value of such  Additional  Interest,  in each case,  without
regard to any  applicable  grace  period.  Notwithstanding  any other  provision
herein,  no  interest  shall  accrue  or  be  payable  in  accordance  with  the
immediately  preceding  sentence  on any  Deferred  Basic  Interest  (as defined
below).

               Interest  on the  PHONES  shall  be  computed  on the  basis of a
360-day year of twelve 30-day months.

2.  Deferral of Interest Payments

               If no Event of Default has occurred and is  continuing  under the
PHONES, the Company may, on one or more occasions,  beginning after the February
15, 2003 payment,  defer payments of Basic Interest  ("Deferred Basic Interest")
for up to twenty  (20)  consecutive  quarterly  periods.  Any  deferral of Basic
Interest may not extend beyond the Maturity  Date, and the Company may not defer
distributions of Additional Interest or quarterly payments equal to regular cash
dividends paid on the maximum number of Reference Shares.

               If the Company defers payments of Basic Interest,  the Contingent
Principal  Amount  shall  increase  during  each  quarter  by the amount of such
Deferred Basic Interest (plus accrued  interest  thereon at an annual rate equal
to 2.50%,  compounded  quarterly  ("Accrued  Interest") ) and the Early Exchange
Ratio (as defined  below) shall be 100% of the Reference  Shares for the quarter
following such  deferral.  Once the Company has paid all Deferred Basic Interest
(plus Accrued  Interest),  together with the Basic Interest for the then current
quarterly period,  the Contingent  Principal Amount shall decrease by the amount
of the payment of such Deferred  Basic  Interest  (plus Accrued  Interest),  the
Early Exchange Ratio will change to 95% of the Reference Shares, and the Company
may again defer  Basic  Interest as  described  above.  The Company may only pay
Deferred Basic Interest (plus Accrued Interest) on an Interest Payment Date.

               If the Company elects to defer payments of Basic Interest for any
quarterly  period,  the Company  shall  provide the Trustee  with notice of such
election (a "Deferral  Notice") and shall  prepare a press  release  relating to
such deferral to be provided to DTC for dissemination  through the DTC broadcast
facility.  The  Deferral  Notice with respect to any  quarterly  period shall be
given to the Trustee not later than one (1)  Business Day before the earlier of:
(i) the Regular Record Date for the payment of Basic Interest for such quarterly
period;  or (ii) the date that the  Company is  required  to give  notice to The
Nasdaq Stock Market (or any other applicable self-regulatory organization) or to
the  Holders  of the PHONES as of such  Regular  Record  Date or the  applicable
Interest Payment Date.


                                       6
<PAGE>

               The  Deferral  Notice  shall  be in  the  form  of  an  Officers'
Certificate to the Trustee  setting forth:  (i) the period with respect to which
the Company is electing to defer Basic Interest;  (ii) the amount of increase of
Contingent  Principal  Amount per PHONES;  (iii) the total amount of increase of
the Contingent  Principal  Amount for all outstanding  PHONES;  (iv) a statement
that the Early  Exchange Ratio will change to 100% of the Reference  Shares,  or
will  continue  at such  rate,  prospectively  from such date for the  following
quarter;  and (v) that no Event of Default has occurred and is continuing  under
the PHONES.  The Company  shall  deliver a Deferral  Notice for each deferral of
Basic Interest.

               If and when the Company pays all of the Deferred  Basic  Interest
and Accrued  Interest,  the Company  shall  deliver to the Trustee an  Officers'
Certificate  setting forth:  (i) the  calculation of Deferred Basic Interest and
Accrued  Interest  owed per  PHONES;  (ii) the total  amount of  Deferred  Basic
Interest and Accrued Interest owed on all outstanding PHONES;  (iii) a statement
that the  Early  Exchange  Ratio  will  change  to 95% of the  Reference  Shares
prospectively  from  such date for the  following  quarter;  (iv) the  amount of
decrease of the Contingent Principal Amount per PHONES; and (v) the total amount
of decrease of the Contingent Principal Amount for all outstanding PHONES.

3.  Principal Amount

               The  "Original  Principal  Amount" per PHONES is equal to $67.75.
The  minimum  amount  payable  upon  redemption  or maturity of each PHONES (the
"Contingent  Principal  Amount")  shall  be  initially  equal  to  the  Original
Principal  Amount.  The  Contingent  Principal  Amount for each  PHONES  will be
increased during each quarter,  based on the Contingent  Principal Amount at the
beginning of the Interest Payment Period, by an amount equal to interest accrued
on such beginning  Contingent Principal Amount at the Basic Interest Rate on the
PHONES  then in effect,  and,  on the dates the  following  amounts  are paid to
Holders of the PHONES,  will be reduced by: (a) each Basic Interest Payment made
on the  PHONES,  (b) any amounts  paid on the PHONES in respect of regular  cash
dividends  paid  on the  Reference  Shares  during  that  quarter  and  (c)  any
Additional  Interest  paid  on the  PHONES.  In no  event  will  the  Contingent
Principal Amount be less than zero.  Notwithstanding the foregoing, in the event
that the Company  redeems  the PHONES on a date which is between  February 6 and
February 15, 2003 (not  including  February 6 or February  15),  the  Contingent
Principal  Amount  will not be  increased  by an  amount  equal to the  interest
accrued on the beginning  Contingent  Principal  Amount for the Interest Payment
Period beginning on November 15, 2002.


                                       7
<PAGE>

               For purposes of the Indenture, the "principal" of a PHONES on any
day and for any purpose  means the amount that is payable  with  respect to such
PHONES as of such date and for such purpose (including without limitation,  upon
any redemption at the option of the Company,  upon any exchange at the option of
the Holder of such  PHONES and upon the  acceleration  of the  maturity  of such
PHONES).  For purposes of the Indenture,  "Interest" on a PHONES for any purpose
includes  Basic  Interest,  any regular  cash  dividends  paid on the  Reference
Shares, Additional Interest and any Final Period Distribution.

               At  maturity,  the Holder of each  PHONES  shall be  entitled  to
receive the Maturity Amount.  The "Maturity  Amount" per PHONES means the higher
of: (i) the  Contingent  Principal  Amount of the PHONES on the Maturity Date or
(ii) the sum of (1) the then  Current  Market  Value (as  defined  below) of the
Reference  Shares on the Maturity Date  attributable  to each PHONES and (2) any
Deferred Basic Interest  (including any Accrued Interest),  plus, in the case of
either (i) or (ii), the Final Period Distribution.

               "Final Period  Distribution"  per PHONES means, in respect of (i)
the Maturity Date, a distribution determined in accordance with clauses (2), (3)
and (4) below and (ii) the Redemption  Date (as defined  below),  a distribution
determined  in  accordance  with  clauses (1),  (2),  (3) and (4) below.  If the
Redemption  Date is in connection  with a Rollover  Offering (as defined below),
the   distribution   determined  in  accordance  with  clause  (4)  shall  be  a
distribution  equal to all dividends and  distributions  on or in respect of the
Reference  Shares which a holder of the Reference Shares on the Pricing Date (as
defined below) would be entitled to receive.

          (1)  Unless (i) the Redemption  Date of the PHONES is also an Interest
               Payment  Date or (ii) Basic  Interest  has been  deferred for the
               then  current  quarterly  period,  an  amount  equal to the Basic
               Interest Rate accrued on the Original  Principal  Amount from the
               most recent Interest  Payment Date to the Redemption  Date, or to
               the next Interest Payment Date in the case of a redemption of the
               PHONES on a date which is between  February  6 and  February  15,
               2003 (not including February 6 or February 15), plus

          (2)  a   distribution   equal  to  the  sum  of  all   dividends   and
               distributions  on or in respect of the Reference  Shares declared
               by the  applicable  Reference  Company (as defined below) and for
               which the ex-date for the dividend or  distribution  falls during
               the period  from the date of  original  issuance of the PHONES to
               the most  recent  Interest  Payment  Date and which have not been
               distributed  to holders  of


                                       8
<PAGE>

               Reference  Shares prior to the most recent Interest Payment Date,
               plus

          (3)  a   distribution   equal  to  the  sum  of  all   dividends   and
               distributions  on or in respect of the  Reference  Shares which a
               holder of Reference  Shares on the latest  ex-date for a dividend
               or distribution  occurring during the period from the most recent
               Interest Payment Date to the date immediately preceding the first
               Trading  Day (as  defined  below)  of the  Averaging  Period  (as
               defined below) is entitled to receive, plus

          (4)  a  distribution  equal to the sum of, for each  successive day in
               the Averaging  Period that is anticipated on the first day of the
               Averaging  Period to be a Trading Day, the amounts  determined in
               accordance with the following formula:

               E x (1 - 0.05n)

where:

               E=   all  dividends  and  distributions  on or in  respect of the
                    Reference  Shares which a holder of the Reference  Shares on
                    the  applicable  day would be entitled to receive,  provided
                    that the ex-date for the dividend or distribution  date that
                    occurs on a day that is not a scheduled Trading Day shall be
                    deemed  to  have  occurred  on  the  immediately   preceding
                    scheduled Trading Day; and

               n=   the number of  scheduled  Trading  Days that have elapsed in
                    the  Averaging  Period  with the  first  Trading  Day of the
                    Averaging Period being counted as zero.

               The  Holder  of  each   PHONES  is  only   entitled   to  receive
distributions  determined  in  accordance  with  clauses  (2), (3) or (4) to the
extent actually distributed by the applicable  Reference Company.  Distributions
related to cash amounts paid by the  applicable  Reference  Company on Reference
Shares as described in clauses (2), (3) or (4) before the Redemption Date or the
Maturity Date, as the case may be, shall be paid on the  Redemption  Date or the
Maturity Date, as the case may be.  Distributions  related to all other property
distributed,  or the cash value of such property,  shall be  distributed  within
twenty (20) Business Days after the Reference Shares Distribution Date.


                                       9
<PAGE>

               Upon  maturity,  the  Company  shall  deliver  to the  Trustee an
Officers'  Certificate  (i)  informing  the Trustee of the  applicable  Maturity
Amount  per  PHONES  and in the  aggregate  for all  outstanding  PHONES and the
Company's  calculation  thereof  and (ii)  directing  the  Trustee to adjust the
Trustee's records and to request DTC to adjust DTC's records.

               Notwithstanding  any other  provision  hereof,  if the Contingent
Principal  Amount is reduced to zero or if all of the Reference  Shares cease to
be  outstanding,  the PHONES  shall  continue  to remain  outstanding  until the
Maturity Date unless the Company shall elect to earlier  redeem the PHONES,  and
each Holder of PHONES will receive the Contingent  Principal  Amount, if any, on
the Redemption Date or the Maturity Date, as applicable.

4.  Exchange Option

               The Holder of each  PHONES  shall  have a right,  at any time and
from time to time, to exchange (an  "Exchange  Right") each PHONES for an amount
of cash equal to a  percentage  of the then  Exchange  Market  Value (as defined
below) of the Reference Shares  attributable to each PHONES (the "Early Exchange
Ratio").  The Early Exchange Ratio at any time shall be equal to: (i) 95% of the
then Exchange Market Value of the Reference  Shares  attributable to each PHONES
or (ii) during a deferral of Basic Interest or, if the Company so elects, during
the pendency of any tender or exchange  offer for any of the  Reference  Shares,
100% of the then Exchange Market Value of the Reference  Shares  attributable to
each PHONES. The Company shall pay the Holder of each PHONES the amount due upon
exchange as soon as reasonably practicable after such Holder delivers notice (an
"Exchange  Notice") to the Trustee,  but in no event  earlier than three Trading
Days after the date of such  Exchange  Notice or later than fifteen (15) Trading
Days after the date of such Exchange Notice.

               "Exchange  Market  Value"  means the  Closing  Price (as  defined
below) on the  Trading  Day  following  the date a Holder of PHONES  delivers an
Exchange  Notice to the Trustee (an  "Exchange  Date");  provided,  however,  if
Exchange Notices relating to more than 200,000 PHONES have been delivered on any
Exchange Date, then the Exchange Market Value shall be the average Closing Price
on the five (5) Trading Days following  such Exchange Date. If Exchange  Notices
relating to more than 200,000  PHONES are  delivered on any Exchange  Date,  the
Trustee shall notify the Company of such fact by 6:00 p.m.,  New York City time,
on the Exchange  Date, and the Company shall give notice of such fact by issuing
a press release prior to 9:00 a.m., New York City time, on the next Trading Day,
which  shall be  provided to DTC for  dissemination  through  the DTC  broadcast
facility and to the Trustee. The Company's failure to provide this


                                       10
<PAGE>

notice,  however, shall not affect the determination of Exchange Market Value as
described above.

               If the PHONES are held through DTC, the Holder of each PHONES may
exercise such Holder's Exchange Right through the relevant direct participant in
DTC through the DTC ATOP system by delivering an agent's  message and delivering
the PHONES of such  Holder to the  Trustee's  DTC  participant  account.  If the
PHONES are held in  certificated  form,  the Holder may exercise  such  Exchange
Right as follows:  the Holder shall (i)  complete and manually  sign an Exchange
Notice in the form available  from the Trustee and deliver such Exchange  Notice
to the Trustee at the office  maintained by the Trustee for such  purpose,  (ii)
surrender  such PHONES to the Trustee,  (iii) if required,  furnish  appropriate
endorsement and transfer  documents,  and (iv) if required,  pay all transfer or
similar taxes.

               By 12:00 noon, New York City time, on each Business Day following
receipt by the Trustee of notification from DTC that DTC has received an agent's
message from a DTC participant electing to exercise such participant's  Exchange
Right and delivery of such PHONES into the Trustee's DTC participant  account or
following  receipt of a complete  manually signed Exchange Notice and receipt of
the related PHONES from the Holder,  the Trustee shall notify the Company of the
amount of such  PHONES so  tendered.  The  Company  shall  deliver an  Officers'
Certificate  to the Trustee no later than one (1) Business Day after the Trading
Day following the Exchange Date;  provided however, if Exchange Notices relating
to more than  200,000  PHONES have been  delivered  on any  Exchange  Date,  the
Company shall deliver such Officers'  Certificate no later than one (1) Business
Day after the fifth  (5th)  Trading  Day  following  such  Exchange  Date.  Such
Officers'  Certificate  shall set forth the amount to be paid to such  tendering
Holder and the date of payment of such amount (the "Exchange Payment Date"). The
Company shall deposit such amount with the Trustee on the Exchange Payment Date,
and upon receipt of such payment from the Company, the Trustee shall pay DTC, as
soon as  practicable  or,  in the case of PHONES  that are held in  certificated
form, as directed by the tendering Holder.

               The date on which  all of the  foregoing  requirements  have been
satisfied shall be the Redemption Date with respect to the PHONES  delivered for
exchange.

5.  Redemption

               The Company may redeem, at any date (the "Redemption  Date"), the
PHONES  in whole  but not in part (a  "Redemption")  at a  redemption  price per
PHONES (the "Redemption  Amount") equal to the sum of: (i) the higher of (A) the
Contingent  Principal  Amount per PHONES or (B) the sum of (1) the then  Current
Market Value of


                                       11
<PAGE>

the Reference Shares on the Redemption Date  attributable to each PHONES and (2)
any Deferred  Basic Interest  (plus Accrued  Interest) per PHONES;  plus, in the
case of either (A) or (B), the Final Period Distribution; and (ii) a "Redemption
Premium" in an amount  equal to $14.9407  per PHONES if the Company  redeems the
PHONES prior to the first quarterly  Interest  Payment Date on May 15, 2000, and
such amount as successively reduced by $1.2280 per PHONES if the Company redeems
the PHONES prior to each following  quarterly  Interest Payment Date through the
twelfth  quarterly  Interest  Payment Date on February 15, 2003;  except that no
such  amount  referred  to in this clause (ii) shall be payable in the event the
PHONES are redeemed  between  February 6 and  February  15, 2003 (not  including
February 6 or February 15). In addition, if any Additional Interest Distribution
Date falls after the Redemption  Date, the Company shall make such  distribution
on the Additional Interest Distribution Date.

               The "Current  Market Value" (other than in the case of a Rollover
Offering,  as defined below) is defined in respect of: (i) the Maturity Date, as
the average  Closing Price per  Reference  Share on the twenty (20) Trading Days
(the  "Averaging  Period")  immediately  prior to (but not  including) the fifth
(5th) Business Day preceding the Maturity Date; and (ii) the Redemption Date, as
the average  Closing  Price per  Reference  Share  during the  Averaging  Period
immediately  prior to (but not including) the fifth (5th) Business Day preceding
the Redemption  Date;  provided,  however,  that for purposes of determining the
payment  required  upon  Redemption  in  connection  with a  Rollover  Offering,
"Current  Market  Value"  means the  Closing  Price per  Reference  Share on the
Trading Day immediately  preceding the date that the Rollover Offering is priced
(the "Pricing Date") or, if the Rollover Offering is priced after 4:00 p.m., New
York City time,  on the Pricing Date,  the Closing Price per Reference  Share on
the  Pricing  Date,  except  that if  there  is not a  Trading  Day  immediately
preceding the Pricing Date or (where  pricing  occurs after 4:00 p.m.,  New York
City  time,  on the  Pricing  Date) if the  Pricing  Date is not a Trading  Day,
"Current  Market  Value"  means the market value per  Reference  Share as of the
Redemption Date as determined by a nationally recognized  independent investment
banking firm retained by the Company.

               A "Rollover Offering" means a refinancing of the PHONES by way of
either (i) a sale of the Reference  Shares or (ii) a sale of securities that are
priced by  reference to the  Reference  Shares,  in either  case,  by means of a
completed  public or private  offering or  offerings by the Company and which is
expected to yield net proceeds which are sufficient to pay the Redemption Amount
for all of the PHONES.  The Trustee will notify the Holders of the PHONES if the
Company elects to redeem the PHONES in connection  with a Rollover  Offering not
less than  thirty  (30) nor more than  sixty  (60)  Business  Days  prior to the
Redemption Date. The Company will also issue a press release prior to 4:00 p.m.,
New York City time, on the Business Day immediately prior to the day


                                       12
<PAGE>

on which the Closing  Price of the  Reference  Shares is to be measured  for the
purpose of determining  the Current  Market Value in connection  with a Rollover
Offering.  Such notice shall state that the Company is firmly committed to price
the Rollover Offering,  shall specify the date on which the Rollover Offering is
to be priced  (including  whether the Rollover  Offering  shall be priced during
trading on the Pricing  Date or after the close of trading on the Pricing  Date)
and  consequently,  whether the Closing Price for the Reference  Shares by which
the Current  Market  Value shall be measured  shall be the Closing  Price on the
Trading Day  immediately  preceding the Pricing Date or the Closing Price on the
Pricing  Date.  The  Company  shall  provide  such  press  release  to  DTC  for
dissemination through the DTC broadcast facility.

               The "Closing Price" of any security on any date of  determination
means the closing sale price (or, if no closing sale price is reported, the last
reported sale price) of such  security  (regular way) on The Nasdaq Stock Market
on such date or, if such  security is not listed for trading on The Nasdaq Stock
Market on that date, as reported in the composite transactions for the principal
United States  securities  exchange on which such  security is so listed,  or if
such  security  is not  so  listed  on a  United  States  national  or  regional
securities  exchange,  the  last  quoted  bid  price  for such  security  in the
over-the-counter  market as reported by the National Quotation Bureau or similar
organization.  In the event that no such quotation is available for any day, the
Board of Directors shall be entitled to determine the Closing Price on the basis
of such quotations as it in good faith considers appropriate. To the extent that
trading of Reference  Shares normal way continues  past 4:00 p.m., New York City
time,  "Closing Price" shall be deemed to refer to the price at the time that is
then customary for  determining the Trading Day's index levels for stocks traded
on the primary  national  securities  exchange or automated  quotation system on
which the  Reference  Shares are then traded or quoted.  All  references to 4:00
p.m.,  New York City time,  in the  definition  of Current  Market  Value  shall
thereafter be deemed to refer to the then customary determination time.

               A "Trading  Day" is defined as a day on which the  security,  the
Closing Price of which is being determined, (i) is not suspended from trading on
any national or regional  securities exchange or association or over-the-counter
market  at the  close  of  business  and (ii) has  traded  at least  once on the
national or regional  securities  exchange or  association  or  over-the-counter
market that is the primary market for the trading of such security.

               In case of any Redemption  (other than a Redemption in connection
with a Rollover  Offering),  the Company shall give thirty (30)  Business  Days'
notice to the Trustee and to the  Holders of the PHONES of such  Redemption  and
the Redemption  Date,  such notice to include the issuance of a press release by
the Company,  which press  release  shall also be provided by the Company to DTC
for dissemination through the DTC


                                       13

<PAGE>

broadcast facility.  On the fifth Business Day preceding the Redemption Date (or
as soon as practicable thereafter),  the Company shall provide to the Trustee an
Officer's  Certificate  and  prepare a press  release to be  provided to DTC for
dissemination through the DTC broadcast facility. Such Officer's Certificate and
press  release shall set forth on a per PHONES and an aggregate  basis,  (i) the
Redemption  Amount,  (ii) the Contingent  Principal  Amount as of the Redemption
Date,  (iii) the Current  Market  Value of the  Reference  Shares,  and (iv) the
Deferred  Basic  Interest  in  respect of such  Redemption.  The  Company  shall
irrevocably  deposit  with the Trustee  sufficient  funds to pay the  Redemption
Amount  on the  Redemption  Date.  Distributions  to be  paid on or  before  the
Redemption  Date  shall be payable  to the  Holders on the record  dates for the
related  dates  of  distribution.   In  addition,  if  any  Additional  Interest
Distribution  Date falls after the Redemption  Date, the Company shall make such
distribution on the Additional Interest Distribution Date.

               Once  notice of  Redemption  is given  and funds are  irrevocably
deposited,  interest  on the  PHONES  shall  cease to  accrue  on and  after the
Redemption Date and all rights of the Holders shall cease,  except for the right
of such Holders to receive the Redemption  Amount (but without  interest on such
Redemption Amount).

               If the Redemption Date is not a Business Day, then the Redemption
Amount  shall be payable on the next  Business  Day (and without any interest or
other payment in respect of any such delay).

               If the Company  improperly holds or refuses to pay any Redemption
Amount,  interest on the PHONES shall  continue to accrue at a rate equal to the
Basic Interest Rate then in effect,  even if such rate is lower than the rate in
effect when the amount owed  originally  accrued,  from the original  Redemption
Date (the "Original Redemption Date") to the actual date of payment (the "Actual
Redemption  Date"). In such case, the Actual Redemption Date shall be considered
the Redemption Date for purposes of calculating the Redemption Amount. The Final
Period  Distribution shall be deemed paid on the Original Redemption Date to the
extent paid as set forth in the definition of Final Period Distribution above.

6.  Reference Share Adjustments

               For  purposes   hereof,   "Reference   Company"  means  McLeodUSA
Incorporated,  a Delaware corporation  ("McLeodUSA"),  and any other issuer of a
Reference Share. A "Reference Share" means,  collectively (i) initially,  0.8772
share of  McLeodUSA's  Class A Common  Stock,  par value  $0.01 (the  "McLeodUSA
Stock");  (ii) and, after the date hereof,  each share or fraction of a share of
publicly traded equity  securities  received by a holder of a Reference Share in
respect of such Reference Share


                                       14
<PAGE>

and, to the extent that the Reference Share remains outstanding after any of the
following events but without duplication, including the Reference Share, in each
case directly or as the result of successive applications of this paragraph upon
any  of the  following  events:  (A)  the  distribution  on or in  respect  of a
Reference Share in Reference  Shares;  (B) the  combination of Reference  Shares
into a  smaller  number  of  shares  or  other  units;  (C) the  subdivision  of
outstanding  shares or other units of Reference  Shares;  (D) the  conversion or
reclassification   of  Reference   Shares  by  issuance  or  exchange  of  other
securities;  (E) any  consolidation  or merger of a  Reference  Company,  or any
surviving  entity or  subsequent  surviving  entity of a  Reference  Company  (a
"Reference Company Successor"), with or into another entity (other than a merger
or  consolidation in which the Reference  Company is the continuing  corporation
and in which the Reference Company common stock outstanding immediately prior to
the merger or  consolidation  is not  exchanged  for cash,  securities  or other
property of the  Reference  Company or another  corporation);  (F) any statutory
exchange  of  securities  of the  Reference  Company  or any  Reference  Company
Successor with another  corporation  (other than in connection  with a merger or
acquisition  and other than a  statutory  exchange  of  securities  in which the
Reference  Company  is the  continuing  corporation  and in which the  Reference
Company common stock outstanding  immediately prior to the statutory exchange is
not exchanged for cash, securities or other property of the Reference Company or
another corporation);  or (G) any liquidation,  dissolution or winding up of the
Reference  Company or any Reference Company  Successor;  and (iii) any Reference
Share as adjusted by any Reference Share Offer Adjustment (as defined below).

               A  "Reference  Share  Offer"  means any tender  offer or exchange
offer  made for all or a portion of a class or series of  Reference  Shares of a
Reference Company. If a Reference Share Offer is made, the Company shall, at its
option,  either: (i) during the pendency of the Reference Share Offer,  increase
the Early  Exchange  Ratio to 100% of the  Reference  Shares and, if the Company
exercises  this  option  prior  to  February  15,  2003,  agree  to pay to  each
exchanging  Holder of a PHONES an amount  equal to the  Redemption  Premium that
would be owed to such Holder if the Company had  redeemed the PHONES on the date
of exchange; or (ii) make a Reference Share Offer Adjustment.

               A "Reference Share Offer Adjustment" means including as part of a
Reference Share each share of publicly traded equity securities,  if any, deemed
to be distributed on or in respect of a Reference  Share as Average  Transaction
Consideration  (as  defined  below)  less  the  Reference  Share   Proportionate
Reduction (as defined below).

               "Average  Transaction  Consideration"  deemed to be received by a
holder of one Reference  Share in a Reference  Share Offer shall be equal to (i)
the  aggregate  consideration  actually  paid or  distributed  to all holders of
Reference Shares that participated in the Reference Share Offer, divided by (ii)
the total number of Reference


                                       15
<PAGE>

Shares  outstanding  immediately  prior to the expiration of the Reference Share
Offer and entitled to participate in such Reference Share Offer.

               A "Reference Share Proportionate Reduction" means a proportionate
reduction  in the  number  of  Reference  Shares  which are the  subject  of the
applicable  Reference Share Offer and  attributable to one PHONES  calculated in
accordance with the following formula:

                                  R=  X
                                     --
                                      N
where:

               R=   the fraction by which the number of Reference  Shares of the
                    class of Reference  Shares  subject to the  Reference  Share
                    Offer and attributable to one PHONES shall be reduced.

               X=   the  aggregate  number of  Reference  Shares of the class or
                    series of Reference  Shares  subject to the Reference  Share
                    Offer accepted in the Reference Share Offer.

               N=   the  aggregate  number of  Reference  Shares of the class of
                    series of Reference  Shares  subject to the Reference  Share
                    Offer outstanding immediately prior to the expiration of the
                    Reference Share Offer.

               If the Company elects to make a Reference Share Offer Adjustment,
the Company will  distribute  as  Additional  Interest  the Average  Transaction
Consideration  (other than Average  Transaction  Consideration  that is publicly
traded equity  securities  which will themselves  become  Reference  Shares as a
result of a  Reference  Share  Offer  Adjustment)  deemed to be  received on the
Reference Shares of the class or series subject to the Reference Share Offer and
attributable to each PHONES  immediately prior to giving effect to the Reference
Share Proportionate Reduction relating to such Reference Share Offer.

               If the Company elects to make a Reference Share Offer Adjustment,
and during the pendency of the  Reference  Share Offer another  Reference  Share
Offer is commenced in relation to the  Reference  Shares that are the subject of
the then  existing  Reference  Share Offer,  the Company may change its original
election  by  electing  to  increase  the  Early  Exchange  Ratio to 100% of the
Reference  Shares and agreeing to pay the other amounts  described  above during
the pendency of the new  Reference  Share Offer,  or the Company may continue to
elect to make a Reference Share Offer Adjustment. The


                                       16
<PAGE>

Company  shall  similarly  be entitled to change its  election  for each further
Reference  Share Offer made during the pendency of any Reference Share Offer for
the same class of Reference  Shares.  For the purposes of these  adjustments,  a
material change to the terms of an existing Reference Share Offer will be deemed
to be a new Reference Share Offer.

               If the Company  elects to increase  the Early  Exchange  Ratio to
100% of the Reference  Shares in  connection  with a Reference  Share Offer,  no
Reference  Share Offer  Adjustment  shall be made and the Company may not change
such election if any further Reference Share Offer is made.

               The  Company  shall  give the  Trustee  notice  of the  Company's
election in the event of a Reference Share Offer. The Company shall also prepare
a press release and provide such press release to DTC for dissemination  through
the DTC broadcast facility. The Company shall give such notice no later than ten
(10) Business Days before the scheduled expiration of the Reference Share Offer.

7.  Acceleration of PHONES

               If an Event of Default with respect to the PHONES shall occur and
be  continuing,  the  Maturity  Amount of all  PHONES  then  outstanding  may be
declared,  or may become,  due and payable upon the conditions and in the manner
and with the effect provided in the Indenture.

8.  Calculations in Respect of the PHONES

               The  Company  shall be  responsible  for making all  calculations
required under the PHONES, including,  without limitation, the determination of:
(i) the  Contingent  Principal  Amount;  (ii) the  Current  Market  Value of the
Reference Shares;  (iii) the Exchange Market Value of the Reference Shares; (iv)
the Final Period  Distribution  on the PHONES;  (v) the fair market value of any
property  distributed  on the  Reference  Shares;  (vi) the Average  Transaction
Consideration; (vii) the composition of a Reference Share; (viii) the Redemption
Amount; (ix) the Maturity Amount; (x) Basic Interest;  (xi) Additional Interest;
and (xii) the amount of Accrued  Interest payable upon Redemption or at Maturity
of the PHONES.

               The Company shall make all such  calculations  in good faith and,
absent manifest error, such  calculations  shall be final and binding on Holders
of the PHONES.  The Company shall provide a schedule of such calculations to the
Trustee  and the Trustee  shall be  entitled  to rely upon the  accuracy of such
calculations without independent verification.


                                       17

9.  Amount Payable Upon Bankruptcy

               Upon  dissolution,  winding-up,  liquidation  or  reorganization,
whether voluntary or involuntary or in bankruptcy,  insolvency,  receivership or
other similar  proceedings in respect of the Company,  Holders of the PHONES may
be entitled to a claim  against  the Company  with  respect to each PHONES in an
amount equal to the higher of: (i) the Contingent  Principal  Amount or (ii) the
sum of  (1)  the  then  Current  Market  Value  (without  giving  effect  to the
provisions   relating  to  any  Rollover   Offering)  of  the  Reference  Shares
attributable  to  each  PHONES  and  (2)  any  unpaid  Deferred  Basic  Interest
(including  any Accrued  Interest)  plus, in the case of either (i) or (ii), the
Final  Period  Distribution  determined  as if the date of such  event  were the
Maturity Date of the PHONES.

10.  Discharge and Defeasance

               The Indenture  contains  provisions  for defeasance of the entire
indebtedness  of the PHONES upon  compliance  with certain  conditions set forth
therein, which provisions shall not apply to the PHONES.

11.  Amendment; Waiver

               The  Indenture  permits,   with  certain  exceptions  as  therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Company and the  Guarantor  and the rights of the Holders of
the PHONES under the Indenture at any time by the Company, the Guarantor and the
Trustee  with the consent of the  Holders of a majority  in  Original  Principal
Amount of the  PHONES  at the time  outstanding.  The  Indenture  also  contains
provisions permitting the Holders of specified percentages in Original Principal
Amount of the PHONES at the time  outstanding,  on behalf of the  Holders of all
PHONES,  to waive  compliance  by the  Company  or the  Guarantor  with  certain
provisions of the  Indenture  and certain past Defaults  under the Indenture and
their  consequences.  Any such  consent or waiver by the  Holder of this  PHONES
shall be conclusive  and binding upon such Holder and upon all future Holders of
this PHONES and of any PHONES issued upon the  registration of transfer  thereof
or in  exchange  herefor  or in lieu  hereof,  whether or not  notation  of such
consent or waiver is made upon this PHONES.  Notwithstanding any other provision
of this PHONES or the Indenture, no supplemental indenture,  without the consent
of the Holders of each PHONES shall:

               (a)  reduce the amount of PHONES whose Holders must consent to an
                    amendment or waiver;


                                       18
<PAGE>

               (b)  change  the  rate  or the  time  for  payment  of  interest,
                    including  Basic Interest,  Additional  Interest and amounts
                    relating to cash dividends on the Reference Shares;

               (c)  change the principal or the fixed maturity;

               (d)  waive a default  in the  payment  of  principal,  premium or
                    interest;

               (e)  make the PHONES payable in a different currency;

               (f)  make  any  change  in  the   provisions   of  the  Indenture
                    concerning  (i) waiver of existing  Defaults;  (ii) right of
                    Holders of PHONES to receive  payment;  or (iii)  amendments
                    and waivers with consent of Holders of PHONES;

               (g)  impair the right to institute  suit for the  enforcement  of
                    any payment on or after the stated  maturity of such payment
                    or, in the case of  Redemption,  on or after the  Redemption
                    Date; or

               (h)  modify or effect in any manner  adverse to the  Holders  the
                    terms  and   conditions  of  the   Guarantor's   obligations
                    regarding  due and punctual  payment of principal of, or any
                    premium or interest on the PHONES.

12. Payment

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

13. Transfers

               As provided in the Indenture  and subject to certain  limitations
on transfer of this PHONES by DTC or its nominee, the transfer of this PHONES is
registrable by the Registrar,  upon surrender of this PHONES for registration of
transfer  at the office or agency of the Company or the  Guarantor,  as the case
may be, in Milwaukee,  Wisconsin  and the Borough of Manhattan,  The City of New
York, New York,  duly endorsed by, or  accompanied by the written  instrument of
transfer attached hereto duly executed by the Holder hereof or his attorney duly
authorized  in writing,  and  thereupon  one or more new PHONES,  of  authorized
denominations and for the same aggregate  principal  amount,  shall be issued to
the designated  transferee or  transferees.  The Registrar need not register the
transfer  of or  exchange  any PHONES for a period of 15 days before an Interest
Payment Date.


                                       19
<PAGE>

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

               Prior to due  presentment  of this  PHONES  for  registration  of
transfer, the Company, the Guarantor,  the Trustee and any agent of the Company,
the  Guarantor  or the Trustee may treat the person in whose name this PHONES is
registered as the owner hereof for all  purposes,  whether or not this PHONES be
overdue, and none of the Company,  the Guarantor,  the Trustee or any such agent
shall be affected by notice to the contrary.

14. Persons Deemed Owners

               The registered  Holder of this PHONES may be treated as the owner
of it for all purposes.

15. Unclaimed Money

               If money for the payment of principal of, or premium,  if any, or
interest on, any PHONES remains  unclaimed for two years,  the Trustee or paying
agent shall pay the money back to the Company at its 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.

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 PHONES or the Indenture or for any claim based on, in respect
of or by reason of such  obligations or their  creation.  By accepting a PHONES,
each Holder waives and releases all such  liability.  The waiver and release are
part of the consideration for the issue of the PHONES.

17. Registration Rights

               The Holder of this  PHONES is  entitled  to the  benefits  of the
Registration  Rights Agreement,  dated as of February 1, 2000 (the "Registration
Rights Agreement"), among the Company, the Guarantor and the Initial Purchaser.

18. Representation and Warranty by Holders

               Each purchaser of PHONES,  by its  acquisition  thereof,  will be
deemed  to  have  acknowledged,  represented  to and  agreed  with  the  Initial
Purchaser, the Company and the Guarantor as follows:

               (1) Such purchaser  understands and acknowledges  that the PHONES
          have  not  been  registered  under  the  Securities  Act or any  other
          applicable   securities   laws,   are  being  offered  for  resale  in
          transactions  not requiring  registration  under the Securities Act or
          any other  securities laws including sales pursuant to Rule 144A under
          the  Securities  Act,  and  may  not be  offered,  sold  or  otherwise
          transferred except in compliance with the registration requirements of
          the Securities Act or any other applicable securities law, or pursuant
          to an exemption therefrom or in a transaction not subject thereto, and
          in each case in compliance  with the conditions for transfer set forth
          in paragraph (4) below.

               (2) Such purchaser is not an "affiliate"  (as defined in Rule 144
          under the Securities Act) of the Company and it is either:

                    (a) a QIB and is aware that any sale of PHONES to it will be
               made in  reliance on Rule 144A and such  acquisition  will be for
               its own account or for the account of another QIB with respect to
               which it exercises sole investment  discretion and to whom it has
               given  notice  that the PHONES are being sold in reliance on Rule
               144A; or

                    (b) an Institutional  Accredited Investor and, if the PHONES
               are  to  be  purchased  for  one  or  more  accounts   ("investor
               accounts")  for which it is acting as  fiduciary  or agent,  each
               such investor account is an Institutional  Accredited Investor on
               a like basis; in the normal course of its business, it invests in
               or purchases  securities similar to the PHONES and such purchaser
               has such  knowledge  and  experience  in  financial  and business
               matters that it is capable of evaluating  the merits and risks of
               purchasing any of the PHONES and it is aware that it (or any such
               investor account) may be required to bear the economic risk of an
               investment in the PHONES for an indefinite  period of time and it
               (or  such  investor  account)  is able to bear  such  risk for an
               indefinite  period  and such  purchaser  has  agreed to deliver a
               letter  substantially  in the  form of  Exhibit  D to the  Second
               Supplemental Indenture to the Company.

               (3) Such  purchaser  acknowledges  that none of the Company,  the
          Guarantor or the Initial  Purchaser,  or any person  representing  the
          Company,  the


                                       21
<PAGE>

          Guarantor or the Initial Purchaser,  has made any representation to it
          with respect to the Company,  the Guarantor or the offering or sale of
          any  PHONES  other  than the  information  contained  in the  Offering
          Memorandum,  dated January 26, 2000, relating to the PHONES, which has
          been  delivered  to it and upon  which  such  purchaser  is relying in
          making  its   investment   decision   with   respect  to  the  PHONES.
          Accordingly,  such purchaser  acknowledges  that no  representation or
          warranty  is made  by the  Initial  Purchaser  as to the  accuracy  or
          completeness of such materials.  Such purchaser has had access to such
          financial and other information  concerning the Company, the Guarantor
          and the PHONES  (and the  Guarantees)  as it has deemed  necessary  in
          connection with its decision to purchase any of the PHONES,  including
          an  opportunity to ask questions of and request  information  from the
          Initial Purchaser, the Company and the Guarantor.

               (4) Such  purchaser is purchasing the PHONES for its own account,
          or for one or more  investor  accounts  for  which it is  acting  as a
          fiduciary or agent, in each case for  investment,  and not with a view
          to, or for offer or sale in connection with, any distribution  thereof
          in violation of the Securities Act,  subject to any requirement of law
          that the  disposition of its property or the property of such investor
          account or  accounts be at all times  within its or their  control and
          subject to its or their ability to resell such PHONES pursuant to Rule
          144A or any exemption from registration available under the Securities
          Act or pursuant to a  registration  statement  which has been declared
          effective under the Securities  Act. Such purchaser  agrees on its own
          behalf  and  on  behalf  of  any  investor  account  for  which  it is
          purchasing the PHONES, and each subsequent holder of the PHONES by its
          acceptance  thereof  will be deemed to  agree,  not to offer,  sell or
          otherwise transfer the PHONES prior to (x) the date which is two years
          (or such shorter  period of time as permitted by Rule 144(k) under the
          Securities  Act) after the later of the date of original  issue of the
          PHONES  and  the  last  date  on  which  the  Company  or  any  of its
          "affiliates" (as defined in Rule 144 under the Securities Act) was the
          owner of the PHONES  (or any  predecessor  thereto)  or (y) such later
          date,  if any,  as may be  required  by  applicable  law (the  "Resale
          Restriction Termination Date"), unless such sale, offer or transfer is
          made (a) to the  Company,  (b)  pursuant to a  registration  statement
          which has been declared effective under the Securities Act, (c) for so
          long as the PHONES are eligible for resale  pursuant to Rule 144A to a
          person it  reasonably  believes  is a QIB that  purchases  for its own
          account or for the  account of a QIB,  in each case to whom  notice is
          given that the transfer is being made in reliance on Rule 144A, (d) to
          an Institutional  Accredited Investor that is acquiring the PHONES for
          its own account or for the account of such an Institutional Accredited
          Investor for investment  purposes and not with a view to, or for offer
          or sale in  connection  with,  any  distribution  in  violation of the
          Securities


                                       22
<PAGE>

          Act  or (e)  pursuant  to  any  other  available  exemption  from  the
          registration  requirements of the Securities  Act,  subject in each of
          the foregoing  cases to any requirement of law that the disposition of
          its property or the property of such  investor  account or accounts be
          at all times within its or their  control and to  compliance  with any
          applicable  state or other  securities laws. If any resale or transfer
          of the  PHONES is  proposed  to be made  pursuant  to clause (d) above
          prior to the Resale Restriction Termination Date, the transferor shall
          deliver  a letter  from the  transferee  substantially  in the form of
          Exhibit  D to the  Indenture  to the  Company  and  the  Trustee.  The
          foregoing  restrictions  on resale  will not apply  subsequent  to the
          Resale   Restriction   Termination  Date.  Each  purchaser  of  PHONES
          acknowledges  that the Company,  the Guarantor and the Trustee reserve
          the right prior to any offer,  sale or other  transfer of PHONES prior
          to the Resale Restriction  Termination Date pursuant to clauses (d) or
          (e),  above,  to  require  the  delivery  of an  opinion  of  counsel,
          certifications  and/or other information  satisfactory to them and the
          Trustee.  Each purchaser of PHONES  acknowledges that each PHONES will
          contain a legend  substantially in the form on the face of this PHONES
          unless otherwise agreed by the Company, the Guarantor and the Trustee.

               (5) Such purchaser  acknowledges that the Company, the Guarantor,
          the Initial Purchaser, the Trustee and others will rely upon the truth
          and accuracy of the  foregoing  acknowledgments,  representations  and
          agreements   and   agree   that,   if  any  of  the   acknowledgments,
          representations, warranties and agreements deemed to have been made by
          its purchase of the notes are no longer  accurate,  it shall  promptly
          notify the Initial Purchaser. If such purchaser is acquiring any notes
          as a  fiduciary  or  agent  for  one or  more  investor  accounts,  it
          represents that it has sole investment discretion with respect to each
          such   account   and  it  has  full   power  to  make  the   foregoing
          acknowledgments, representations and agreements on behalf of each such
          account  and that each such  investor  account is eligible to purchase
          the PHONES.

               (6) Such purchaser  acknowledges  that the Trustee,  the transfer
          agent  and  the   registrar   will  not  be  required  to  accept  for
          registration  of  transfer  any PHONES  acquired  by it,  except  upon
          presentation  of evidence  satisfactory to the Company and the Trustee
          that the restrictions set forth above have been complied with.

               (7) Such purchaser  acknowledges that the foregoing  restrictions
          apply to holders of beneficial interests in the PHONES, as well as the
          holders of the PHONES.

19.  Sinking Fund

               The  PHONES  do  not  have  the  benefit  of  any  sinking   fund
obligations.

20.  Indenture

               The Company shall furnish to any Holder of record of PHONES, upon
written request and without charge, a copy of the Indenture.

21.  Governing Law

construed in accordance  with the laws of the State of Wisconsin  without regard
to principles of conflicts of law.

22.  Authentication

by the Trustee by manual  signature,  this  PHONES  shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose.

               FOR  VALUE  RECEIVED,   the  Guarantor,   hereby  unconditionally
guarantees to the Holder of the Security  upon which this  Guarantee is endorsed
the due and punctual payment of the principal,  of premium,  if any, or interest
on said Security, when and as the same shall be become due and payable,  whether
at maturity, upon redemption or otherwise, according to the terms thereof and of
the Indenture referred to therein.

               The  Guarantor  agrees to  determine,  at least one  business day
prior to the date upon which a payment of  principal,  of  premium,  if any,  or
interest on said Security is due and payable,  whether the Company has available
the funds to make such payment as the same shall become due and payable. In case
of the failure of the Company punctually to pay any such principal,  premium, if
any, or interest,  the  Guarantor  hereby agrees to cause any such payment to be
made  punctually  when and as the same shall become due and payable,  whether at
maturity, upon redemption or otherwise,  and as if such payment were made by the
Company.

               The Guarantor hereby agrees that its obligations  hereunder shall
be  unconditional,  irrevocable  and  absolute,  irrespective  of the  validity,
regularity or enforceability of said Security or said Indenture,  the absence of
any  action to  enforce  the same,  any  waiver or consent by the Holder of said
Security with respect to any  provisions  thereof,  the recovery of any judgment
against the Company or any action to enforce the same or any other  circumstance
which might otherwise  constitute a legal or equitable discharge or defense of a
guarantor.  The  Guarantor  hereby  waives  diligence,  presentment,  demand  of
payment,  filing of claims with a court in the event of merger or  bankruptcy of
the  Company,  any right to require a  proceeding  first  against  the  Company,
protest  or notice  with  respect to said  Security  or  indebtedness  evidenced
thereby,  and all demands  whatsoever and covenants that this Guarantee will not
be discharged  except by complete  performance of the  obligations  contained in
said Security and in this Guarantee.

               The Guarantor  shall be subrogated to all rights of the Holder of
said  Security  against  the  Company  in  respect  to any  amounts  paid by the
Guarantor pursuant to the provisions of this Guarantee;  provided, however, that
the  Guarantor  shall not,  without  the  consent  of the  Holders of all of the
Securities then  outstanding,  be entitled to enforce or to receive any payments
arising out of or based upon such right of  subrogation  until the  principal of
and premium, if any, and interest on all Securities shall have been paid in full
or  payment  thereof  shall  have  been  provided  for in  accordance  with said
Indenture.

               Notwithstanding  anything to the contrary  contained  herein,  if
following any payment of principal or interest by the Company on the  Securities
to the Holders of the


                                       26

Securities  it is  determined  by a  final  decision  of a  court  of  competent
jurisdiction  that such  payment  shall be avoided  by a trustee  in  bankruptcy
(including any debtor-in-possession) as a preference under 11 U.S.C. Section 547
and such payment is paid by such Holder to such trustee in bankruptcy,  then and
to the extent of such repayment the obligations of the Guarantor hereunder shall
remain in full force and effect.

               This  Guarantee  shall not be valid or become  obligatory for any
purpose with respect to a Security until a certificate of authentication on such
Security shall have been signed by the Trustee (or the authenticating agent).

               This  Guarantee  shall be  governed  by the laws of the  State of

               2. Registration Under the 1933 Act.

               2.1 Exchange Offer.  Except as provided in Section 2.2 and to the
extent not prohibited by any applicable law or applicable  interpretation of the
staff of the SEC,  the  Company  and the Parent  shall,  for the  benefit of the
Holders,  at the cost of the Company and the Parent, (A) prepare and, as soon as
practicable  but not later than 135 days  following the Closing Date,  use their
reasonable  best  efforts to file with the SEC an  Exchange  Offer  Registration
Statement on an  appropriate  form under the 1933 Act with respect to a proposed
Exchange Offer and the issuance and delivery to the Holders, in exchange for the
Registrable  Securities  (other than  Private  Exchange  Securities),  of a like
principal amount of Exchange  Securities,  (B) use their reasonable best efforts
to cause the Exchange  Offer  Registration  Statement  to be declared  effective
under the 1933 Act within 180 days of the Closing Date, (C) use their reasonable
best efforts to keep the Exchange Offer Registration  Statement  effective until
the closing of the Exchange Offer and (D) use their  reasonable  best efforts to
cause the  Exchange  Offer to be  consummated  not later  than 45 days after the
effective  date of the  Exchange  Offer  Registration  Statement.  The  Exchange
Securities  will be issued under the Indenture.  Upon the  effectiveness  of the
Exchange Offer Registration Statement, the Company and the Parent shall promptly
commence the Exchange  Offer,  it being the objective of such Exchange  Offer to
enable each Holder eligible and electing to exchange Registrable  Securities for
Exchange  Securities  (assuming  that such Holder (a) is not an affiliate of the
Company  within  the  meaning  of Rule  405  under  the 1933  Act,  (b) is not a
broker-dealer  tendering  Registrable  Securities  acquired  directly  from  the
Company  for its own  account,  (c)  acquired  the  Exchange  Securities  in the
ordinary  course  of such  Holder's  business  and (d)  has no  arrangements  or
understandings  with any Person to  participate  in the  Exchange  Offer for the
purpose of  distributing  the Exchange  Securities)  to transfer  such  Exchange
Securities  from and after their receipt without any limitations or restrictions
under the 1933 Act and under state securities or blue sky laws.

               In connection with the Exchange Offer, the Company and the Parent
shall:

                    (a) mail as promptly as practicable to each Holder a copy of
          the  Prospectus  forming  part  of  the  Exchange  Offer  Registration
          Statement,  together with an  appropriate  letter of  transmittal  and
          related documents;

                    (b) keep the Exchange Offer open for acceptance for a period
          of not less than 20  business  days after the date  notice  thereof is
          mailed to the Holders (or longer if required by applicable  law) (such
          period referred to herein as the "Exchange Period");


                                       6
<PAGE>

                    (c) utilize the services of the  Depositary for the Exchange
          Offer;

                    (d)  permit   Holders  to  withdraw   tendered   Registrable
          Securities at any time prior to 5:00 p.m.  (Eastern Time), on the last
          business day of the  Exchange  Period,  by sending to the  institution
          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  such  Holder's  election  to have  such
          Securities exchanged;

                    (e) notify  each Holder that any  Registrable  Security  not
          tendered will remain outstanding and continue to accrue interest,  but
          will not retain any rights under this Agreement (except in the case of
          the Initial  Purchaser and  Participating  Broker-Dealers  as provided
          herein); and

                    (f)  otherwise  comply in all respects  with all  applicable
          laws relating to the Exchange Offer.

               If,  prior to  consummation  of the Exchange  Offer,  the Initial
Purchaser holds any Securities acquired by it and having the status of an unsold
allotment  in the  initial  distribution,  the  Company  and the Parent upon the
request of the Initial Purchaser shall,  simultaneously with the delivery of the
Exchange  Securities  in the  Exchange  Offer and  subject  to  compliance  with
applicable  securities  laws,  issue and  deliver to the  Initial  Purchaser  in
exchange  (the  "Private  Exchange")  for the  Securities  held  by the  Initial
Purchaser, a like principal amount of debt securities of the Company on a senior
basis,  that are identical  (except that such securities  shall bear appropriate
transfer  restrictions)  to  the  Exchange  Securities  (the  "Private  Exchange
Securities").

               The Exchange Securities and the Private Exchange Securities shall
be issued  under the  Indenture  which  has been  qualified  under the TIA or is
exempt from such  qualification  and shall provide that the Exchange  Securities
shall not be subject to the transfer restrictions set forth in the Indenture but
that  the  Private  Exchange  Securities  shall  be  subject  to  such  transfer
restrictions.  The  Indenture  shall provide that the Exchange  Securities,  the
Private  Exchange  Securities and the Securities shall vote and consent together
on all  matters  as one  class  and that none of the  Exchange  Securities,  the
Private  Exchange  Securities or the  Securities  will have the right to vote or
consent as a separate class on any matter. The Private Exchange Securities shall
be of the  same  series  as and  the  Company  and  the  Parent  shall  use  all
commercially reasonable efforts to have the Private Exchange Securities bear the
same CUSIP number as the Exchange Securities. Neither the Company nor the Parent
shall have any liability under this Agreement solely as


                                       7
<PAGE>

a result of such Private  Exchange  Securities not bearing the same CUSIP number
as the Exchange Securities.

               As soon as  practicable  after  the close of the  Exchange  Offer
and/or the  Private  Exchange,  as the case may be, the  Company  and the Parent
shall:

                    (i) accept for  exchange  all  Registrable  Securities  duly
          tendered and not validly  withdrawn  pursuant to the Exchange Offer in
          accordance with the terms of the Exchange Offer Registration Statement
          and the letter of transmittal which shall be an exhibit thereto;

                    (ii) accept for exchange all  Securities  properly  tendered
          pursuant to the Private Exchange;

                    (iii)   deliver  to  the   Trustee  for   cancellation   all
          Registrable Securities so accepted for exchange; and

                    (iv) cause the Trustee  promptly to authenticate and deliver
          Exchange  Securities or Private Exchange  Securities,  as the case may
          be, to each Holder of Registrable  Securities so accepted for exchange
          in a principal amount equal to the principal amount of the Registrable
          Securities of such Holder so accepted for exchange.

               Interest on each Exchange  Security and Private Exchange Security
will accrue  from the last date on which  interest  was paid on the  Registrable
Securities  surrendered in exchange therefor or, if no interest has been paid on
the Registrable  Securities,  from the date of original  issuance.  The Exchange
Offer and the Private  Exchange  shall not be subject to any  conditions,  other
than (i) that the Exchange Offer or the Private  Exchange,  or the making of any
exchange  by a  Holder,  does  not  violate  applicable  law or  any  applicable
interpretation  of the staff of the SEC, (ii) the due  tendering of  Registrable
Securities in accordance with the Exchange Offer and the Private Exchange, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have  represented  that all  Exchange  Securities  to be received by it shall be
acquired  in the  ordinary  course of its  business  and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding
with any person to  participate in the  distribution  (within the meaning of the
1933  Act)  of  the  Exchange   Securities   and  shall  have  made  such  other
representations  as may be  reasonably  necessary  under  applicable  SEC rules,
regulations  or  interpretations  to  render  the  use  of  Form  S-4  or  other
appropriate  form  under  the 1933 Act  available  and (iv)  that no  action  or
proceeding shall have been instituted or threatened in any court or by or before
any  governmental  agency  with  respect to the  Exchange  Offer or the  Private
Exchange which, in the


                                       8
<PAGE>

judgment of the Company and the Parent,  would  reasonably be expected to impair
the ability of the Company and the Parent to proceed with the Exchange  Offer or
the Private  Exchange and that the Exchange Offer and the Private Exchange shall
comply with the provisions of the SEC's Release No.  35-27069,  70-9455 dated as
of August  26,  1999 by which the  Parent  and the  Company  are bound (the "SEC
Order").  The Company and the Parent shall  inform the Initial  Purchaser of the
names and addresses of the Holders to whom the Exchange  Offer is made,  and the
Initial  Purchaser  shall have the right to contact such  Holders and  otherwise
facilitate the tender of Registrable Securities in the Exchange Offer.

               2.2 Shelf Registration.  (i) If the law, SEC rules or regulations
or applicable  interpretations  thereof by the staff of the SEC, U.S. Department
of the  Treasury  or the  Internal  Revenue  Service  do not  permit  or make it
impractical or inadvisable for the Company and the Parent to effect the Exchange
Offer as  contemplated  by Section 2.1 hereof,  (ii) if for any other reason the
Exchange Offer Registration  Statement is not declared effective within 180 days
following the Closing Date or the Exchange  Offer is not  consummated  within 45
days after effectiveness of the Exchange Offer Registration  Statement (provided
that if the Exchange Offer  Registration  Statement shall be declared  effective
after such 180-day period or if the Exchange  Offer shall be  consummated  after
such 45-day period, then the obligation of the Company and the Parent under this
clause  (ii)  arising  from  the  failure  of the  Exchange  Offer  Registration
Statement to be declared  effective within such 180-day period or the failure of
the Exchange  Offer to be consummated  within such 45-day period,  respectively,
shall terminate), (iii) upon the request of the Initial Purchaser within 90 days
following the  consummation of the Exchange Offer or (iv) if, as a result of any
changes in law, SEC rules or regulations or applicable  interpretations  thereof
by the staff of the SEC or otherwise, a Holder (other than the Initial Purchaser
holding  securities  acquired  directly  from the  Company) is not  permitted to
participate in the Exchange Offer or does not receive fully  tradeable  Exchange
Securities  pursuant to the Exchange Offer,  then in case of each of clauses (i)
through (iv) the Company and the Parent shall, at their cost:

                    (a) To the extent not  prohibited by any  applicable  law or
          applicable  interpretations  thereof  by  the  staff  of  the  SEC  or
          otherwise,  as  promptly as  practicable,  use their  reasonable  best
          efforts to file with the SEC and  thereafter  to cause to be  declared
          effective as promptly as practicable  but no later than 210 days after
          the Closing Date, a Shelf Registration Statement relating to the offer
          and sale of the  Registrable  Securities  by the Holders  from time to
          time in  accordance  with the methods of  distribution  elected by the
          Majority Holders participating in the Shelf Registration and set forth
          in such Shelf Registration Statement.


                                       9
<PAGE>

                    (b) Use  their  reasonable  best  efforts  to keep the Shelf
          Registration  Statement  continuously effective in order to permit the
          Prospectus  forming  part thereof to be usable by Holders for a period
          of two years from the Closing  Date,  or for such shorter  period that
          will terminate when all  Registrable  Securities  covered by the Shelf
          Registration   Statement   have  been  sold   pursuant  to  the  Shelf
          Registration  Statement or cease to be  outstanding or otherwise to be
          Registrable   Securities  (the  "Effectiveness   Period");   provided,
          however,  that  the  Effectiveness  Period  in  respect  of the  Shelf
          Registration  Statement  shall be extended  to the extent  required to
          permit  dealers  to comply  with the  applicable  prospectus  delivery
          requirements of Rule 174 under the 1933 Act and as otherwise  provided
          herein.

                    (c)  Notwithstanding  any other provisions hereof, use their
          reasonable  best  efforts  to ensure  that (i) any Shelf  Registration
          Statement and any amendment  thereto and any  Prospectus  forming part
          thereof and any supplement  thereto complies in all material  respects
          with the 1933 Act and the rules and regulations  thereunder,  (ii) any
          Shelf Registration  Statement and any amendment thereto does not, when
          it becomes  effective,  contain an 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 not misleading and (iii) any
          Prospectus forming part of any Shelf Registration  Statement,  and any
          supplement to such Prospectus (as amended or supplemented from time to
          time), does not include an untrue statement of a material fact or omit
          to state a material fact necessary in order to make the statements, in
          light of the circumstances under which they were made, not misleading;
          provided,  however, that clauses (ii) and (iii) shall not apply to any
          information  relating to the Initial Purchaser or any Holder furnished
          to the Company in writing by the Initial Purchaser or Holder expressly
          for use in the Shelf Registration Statement.

               The  Company  and the Parent  further  agree,  if  necessary,  to
supplement  or amend the Shelf  Registration  Statement,  as required by Section
3(b) below,  and 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.

               2.3   Expenses.   The  Company  and  the  Parent  shall  pay  all
Registration  Expenses in connection with the  registration  pursuant to Section
2.1 or 2.2. 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.

               2.4. Effectiveness.

               (a) The  Company  and the Parent  will be deemed not to have used
          their reasonable best efforts to cause the Exchange Offer Registration
          Statement or the Shelf Registration  Statement, as the case may be, to
          become,  or to remain,  effective  during the requisite  period if the
          Company and the Parent voluntarily take any action that would, or omit
          to  take  any  action  which  omission  would,   result  in  any  such
          Registration  Statement not being declared effective or in the Holders
          of Registrable  Securities  covered thereby not being able to exchange
          or offer and sell such  Registrable  Securities  during that period as
          and to the extent contemplated hereby,  unless such action is required
          by applicable  law, as  contemplated by clause (i) of Section 2.2, or,
          in the case of the Exchange Offer Registration Statement,  such action
          would violate the provisions of the SEC Order.

               (b) An Exchange Offer Registration  Statement pursuant to Section
          2.1 hereof or a Shelf  Registration  Statement pursuant to Section 2.2
          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 an  Exchange  Offer  Registration  Statement  or 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.

               (c)  Notwithstanding  anything in this Agreement to the contrary,
          during the  Effectiveness  Period,  upon  notice to the Holders of the
          Securities (as described in Section 3(e)(viii) hereunder), the Company
          and the Parent may suspend the availability of the Shelf  Registration
          Statement for up to two (2) periods of up to 30 consecutive days each,
          but not more than an aggregate  of 30 days during any 365-day  period,
          if the  board of  directors  of the  Company  and the  Parent in their
          respective reasonable judgments believe that they may possess material
          non-public  information  that makes it  advisable  to so  suspend  the
          availability of the Shelf Registration Statement.

               3.   Registration Procedures.

               In connection  with and subject to the rights and the obligations
of the Company and the Parent with respect to Registration  Statements  pursuant
to Sections 2.1, 2.2 and 2.4(c) hereof, the Company and the Parent shall:

          effective for the applicable  period;  and cause each Prospectus to be
          supplemented  by  any  required  prospectus  supplement,   and  as  so

          applicable period in accordance with the intended method or methods of
          distribution by the selling Holders  thereof  (including  sales by any

          of  Registrable  Securities,  at least  five  business  days  prior to
          filing,  that a  Shelf  Registration  Statement  with  respect  to the

          the distribution of Registrable  Securities will be made in accordance
          with the method selected by the Majority Holders  participating in the

                                       12
<PAGE>

               (d) use their  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 and each underwriter of
          an underwritten  offering of Registrable  Securities  shall reasonably
          request by the time the applicable  Registration Statement is declared
          effective  by the SEC,  and do any and all other acts and things which
          may be  reasonably  necessary  or advisable to enable each such Holder
          and   underwriter   to  consummate   the   disposition  in  each  such
          jurisdiction  of such  Registrable  Securities  owned by such  Holder;
          provided,  however,  that  neither the Company nor the Parent shall 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), or (ii) take any action
          which  would  subject it to general  service of process or taxation in
          any such jurisdiction where it is not then so subject;

               (e) notify promptly each Holder of Registrable Securities under a
          Shelf Registration or any Participating Broker-Dealer who has notified
          the Company and the Parent that it is  utilizing  the  Exchange  Offer
          Registration  Statement  as  provided in  paragraph  (f) below and, if
          requested by such Holder or Participating Broker-Dealer,  confirm such
          advice in  writing  promptly  (i) when a  Registration  Statement  has
          become   effective  and  when  any   post-effective   amendments   and
          supplements  thereto become effective,  (ii) of any request by the SEC
          or any state securities  authority for  post-effective  amendments and
          supplements  to  a  Registration   Statement  and  Prospectus  or  for
          additional  information  after the  Registration  Statement has become
          effective,  (iii) of the  issuance by the SEC or any state  securities
          authority  of  any  stop  order  suspending  the  effectiveness  of  a
          Registration  Statement or the initiation of any  proceedings for that
          purpose,  (iv) in the case of a Shelf  Registration,  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 and the Parent 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,  (v) of the happening of any event or the discovery
          of any facts  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,  (vi) of the  receipt by the  Company or the Parent of any
          notification  with respect to the suspension of the  qualification  of
          the Registrable Securities or the Exchange Securities, as the case may
          be, for sale


                                       13
<PAGE>

          in any jurisdiction or the initiation or threatening of any proceeding
          for such purpose,  (vii) of any  determination  by the Company and the
          Parent that a post-effective  amendment to such Registration Statement
          would be appropriate  and (viii) of any  determination  to suspend the
          use of the Shelf Registration Statement under Section 2.4(c);

               (f) (A) in the case of the Exchange Offer Registration  Statement
          (i) include in the  Exchange  Offer  Registration  Statement a section
          entitled  "Plan of  Distribution"  which  section  shall be reasonably
          acceptable   to   Merrill   Lynch  on  behalf  of  the   Participating
          Broker-Dealers,  and which shall  contain a summary  statement  of the
          positions  taken or policies made by the staff of the SEC with respect
          to the potential  "underwriter" status of any broker-dealer that holds
          Registrable  Securities  acquired  for its own  account as a result of
          market-making  activities or other trading activities and that will be
          the beneficial owner (as defined in Rule 13d-3 under the Exchange Act)
          of Exchange  Securities  to be received by such  broker-dealer  in the
          Exchange Offer,  whether such positions or policies have been publicly
          disseminated by the staff of the SEC or such positions or policies, in
          the   reasonable   judgment   of  Merrill   Lynch  on  behalf  of  the
          Participating Broker-Dealers and its counsel, represent the prevailing
          views of the staff of the SEC,  including  a  statement  that any such
          broker-dealer  who  receives   Exchange   Securities  for  Registrable
          Securities  pursuant to the  Exchange  Offer may be deemed a statutory
          underwriter and must deliver a prospectus  meeting the requirements of
          the  1933  Act  in  connection   with  any  resale  of  such  Exchange
          Securities,  (ii) furnish to each Participating  Broker-Dealer who has
          delivered  to the  Company  and the Parent the notice  referred  to in
          Section  3(e),  without  charge,  as many  copies  of each  Prospectus
          included in the Exchange Offer Registration  Statement,  including any
          preliminary  prospectus,  and any amendment or supplement  thereto, as
          such Participating  Broker-Dealer may reasonably request, (iii) hereby
          consent  to the use of the  Prospectus  forming  part of the  Exchange
          Offer Registration  Statement or any amendment or supplement  thereto,
          by any Person subject to the prospectus  delivery  requirements of the
          SEC,  including all Participating  Broker-Dealers,  in connection with
          the  sale  or  transfer  of the  Exchange  Securities  covered  by the
          Prospectus or any amendment or supplement thereto, and (iv) include in
          the transmittal  letter or similar  documentation to be executed by an
          exchange offeree in order to participate in the Exchange Offer (x) the
          following provision:

               "If the  exchange  offeree is a  broker-dealer  holding
               Registrable  Securities acquired for its own account as
               a result of  market-making  activities or other trading
               activities,


                                       14

               it will deliver a prospectus  meeting the  requirements
               of the  1933  Act in  connection  with  any  resale  of
               Exchange   Securities   received  in  respect  of  such
               Registrable Securities pursuant to the Exchange Offer;"
               and

          (y) a  statement  to the  effect  that by a  broker-dealer  making the
          acknowledgment  described in clause (x) and by delivering a Prospectus
          in  connection  with  the  exchange  of  Registrable  Securities,  the
          broker-dealer  will not be deemed to admit  that it is an  underwriter
          within the meaning of the 1933 Act; and

                    (B)  in  the  case  of  any  Exchange   Offer   Registration
          Statement,  the Company and the Parent agree to deliver to the Initial
          Purchaser  on  behalf  of the  Participating  Broker-Dealers  upon the
          effectiveness  of the Exchange  Offer  Registration  Statement  (i) an

          attached   hereto   as   Exhibit   A,  (ii)   officers'   certificates
          substantially in the form  customarily  delivered in a public offering

          Standards  No.  72 of  the  American  Institute  of  Certified  Public
          Accountants  (or if such a comfort letter is not permitted,  an agreed
          upon  procedures  letter  in  customary  form)  from  the  independent
          certified  public  accountants  of the Company and the Parent (and, if
          necessary,  any other independent  certified public accountants of any
          subsidiary of the Company or the Parent or of any business acquired by
          the Company or the Parent for which  financial  statements are, or are
          required to be,  included in the  Registration  Statement) at least as
          broad in scope and coverage as the comfort  letter or comfort  letters
          delivered to the Initial Purchaser in connection with the initial sale
          of the Securities to the Initial Purchaser;

               (g) (i) in the case of an Exchange Offer, furnish counsel for the
          Initial  Purchaser  and  (ii) in the  case  of a  Shelf  Registration,
          furnish  counsel for the Holders of Registrable  Securities  copies of
          any comment letters  received from the SEC or any other request by the
          SEC or any state securities authority for amendments or supplements to
          a Registration Statement and Prospectus or for additional information;

               (h) make every reasonable  effort to obtain the withdrawal of any
          order suspending the effectiveness of a Registration  Statement at the
          earliest possible moment;

               (i) in the case of a Shelf  Registration,  furnish to each Holder
          of  Registrable  Securities,  and each  underwriter,  if any,  without
          charge, at least one


                                       15
<PAGE>

          conformed copy of each Registration  Statement and any  post-effective
          amendment  thereto,   including  financial  statements  and  schedules
          (without documents  incorporated therein by reference and all exhibits
          thereto, unless requested);

               (j) 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 or the  underwriters,  if any,  may
          reasonably  request at least three  business days prior to the closing
          of any sale of Registrable Securities;

               (k) in the case of a Shelf  Registration,  upon the occurrence of
          any event or the  discovery  of any  facts,  each as  contemplated  by
          Sections  3(e)(v),  3(e)(vi)  and  3(e)(viii)  hereof,  as promptly as
          practicable   after  the  occurrence  of  such  an  event,  use  their
          reasonable  best  efforts to prepare a  supplement  or  post-effective
          amendment to the 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 or Participating  Broker-Dealers,  such
          Prospectus  will not contain at the time of such  delivery  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  or will
          remain  so  qualified.  At  such  time as such  public  disclosure  is
          otherwise  made or the  Company  and the  Parent  determine  that such
          disclosure is not necessary,  in each case to correct any misstatement
          of a material  fact or to  include  any  omitted  material  fact,  the
          Company  and the Parent  agree  promptly to notify each Holder of such
          determination  and to furnish each Holder such number of copies of the
          Prospectus as amended or  supplemented,  as such Holder may reasonably
          request;

               (l) in the case of a Shelf Registration,  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 Purchaser on behalf of such Holders;  and make representatives
          of the Company and the Parent as shall be reasonably  requested by the
          Holders of Registrable Securities,  or the Initial Purchaser on behalf
          of such  Holders,  available  for  discussion  of such  document  upon
          reasonable  advance

<PAGE>

          notice.  In  connection  with such  discussions,  the  Holders  or the
          Initial  Purchaser,  on  behalf  of  such  Holders,  shall  use  their
          reasonable  best efforts to minimize any disruption to the business of
          the Company and the Parent;

               (m) obtain a CUSIP  number for all Exchange  Securities,  Private
          Exchange Securities or Registrable Securities, as the case may be, not

          the Trustee with  certificates  for the Exchange  Securities,  Private
          Exchange Securities or the Registrable Securities, as the case may be,
          in a form eligible for deposit with the Depositary;

               (n) (i)  cause the  Indenture  to be  qualified  under the TIA in
          connection  with  the  registration  of  the  Exchange  Securities  or
          Registrable  Securities,  as the case may be, (ii)  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 (iii) execute,  and use their 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;

               (o) in the case of a Shelf  Registration,  enter into  agreements
          (including  underwriting  agreements) and take all other customary and
          appropriate actions in order to expedite or facilitate the disposition
          of such Registrable  Securities and in such connection  whether or not
          an  underwriting  agreement  is  entered  into and  whether or not the
          registration is an underwritten registration:

                    (i) make such  representations and warranties to the Holders
               of such Registrable  Securities and the underwriters,  if any, in
               form,  substance and scope as are customarily  made by issuers to

                    (ii)  obtain  opinions  of  counsel to the  Company  and the
               Parent and updates  thereof (which counsel and opinions (in form,

               managing  underwriters,  if any, and the holders of a majority in
               principal  amount  of  the  Registrable  Securities  being  sold)
               addressed to each selling  Holder and the  underwriters,  if any,

               sales of securities or underwritten offerings and

               the independent  certified public  accountants of the Company and
               the Parent (and, if necessary,  any other  independent  certified
               public accountants of any subsidiary of the Company or the Parent
               or of any  business  acquired  by the  Company  or the Parent for
               which  financial  statements are, or are required to be, included
               in the Registration Statement) addressed to the underwriters,  if
               any, and use reasonable  efforts to have such letter addressed to
               the  selling  Holders of  Registrable  Securities  (to the extent
               consistent  with  Statement on Auditing  Standards  No. 72 of the
               American Institute of Certified Public Accountants), such letters
               to  be in  customary  form  and  covering  matters  of  the  type
               customarily  covered in "cold comfort" letters to underwriters in
               connection with similar underwritten offerings;

                    (iv)  enter  into a  securities  sales  agreement  with  the
               Holders and an agent of the Holders  providing  for,  among other
               things, the appointment of such agent for the selling Holders for
               the purpose of soliciting  purchases of  Registrable  Securities,
               which agreement  shall be in form,  substance and scope customary
               for similar offerings;

                    (v) if an underwriting  agreement is entered into, cause the
               same  to set  forth  indemnification  provisions  and  procedures
               substantially  equivalent to the  indemnification  provisions and
               procedures  set forth in  Section 4 hereof  with  respect  to the
               underwriters and all other parties to be indemnified  pursuant to
               said Section or, at the request of any underwriters,  in the form
               customarily  provided to such  underwriters  in similar  types of
               transactions; and

                    (vi)  deliver  such  documents  and  certificates  as may be
               reasonably requested and as are customarily  delivered in similar
               offerings to the Holders of a majority in principal amount of the
               Registrable  Securities being sold and the managing underwriters,
               if any.

          The above shall be done at (i) the  effectiveness of such Registration
     Statement (and each post-effective amendment thereto) and (ii) each closing
     under any  underwriting or similar  agreement as and to the extent required
     thereunder;

          reasonably object, and make the representatives of the Company and the
          Parent  available  for  discussion  of  such  documents  as  shall  be
          reasonably requested by the Initial Purchaser; and

               (ii) in the case of a Shelf Registration, a reasonable time prior
          to filing any Shelf Registration  Statement,  any Prospectus forming a
          part thereof,  any amendment to such Shelf  Registration  Statement or
          amendment or supplement  to such  Prospectus,  provide  copies of such

                                       19
<PAGE>

          which the  Majority  Holders,  the Initial  Purchaser on behalf of the
          Holders  of  Registrable  Securities,   counsel  for  the  Holders  of
          Registrable  Securities or any  underwriter  shall not have previously
          been advised and furnished a copy of or to which the Majority Holders,
          the  Initial  Purchaser  of  behalf  of  the  Holders  of  Registrable
          Securities,  counsel to the Holders of  Registrable  Securities or any

          for the Holders of Registrable Securities or any underwriter.

               (r) following  effectiveness  of a  Registration  Statement,  use
          their  reasonable best efforts to cause all Exchange  Securities to be
          listed on the New York Stock  Exchange if  requested  by the  Majority
          Holders,  or if requested by the  underwriter  or  underwriters  of an
          underwritten offering of Exchange Securities, if any;

               (s) in the case of a Shelf  Registration,  use  their  reasonable
          best efforts to cause the  Registrable  Securities  to be rated by the
          appropriate rating agencies,  if so requested by the Majority Holders,
          or if requested by the  underwriter or underwriters of an underwritten
          offering of Registrable Securities, if any;

               (t) otherwise comply with all applicable rules and regulations of
          the  SEC  and  make  available  to its  security  holders,  as soon as

          of the 1933 Act and Rule 158 thereunder;

               (u) cooperate and assist in any filings  required to be made with
          the NASD and, in the case of a Shelf Registration,  in the performance
          of any due diligence  investigation by any underwriter and its counsel
          (including any "qualified independent underwriter" that is required to
          be retained in accordance with the rules and regulations of the NASD);
          and

               (v) upon consummation of an Exchange Offer or a Private Exchange,
          obtain a  customary  opinion of counsel to the  Company and the Parent
          addressed to the Trustee for the benefit of all Holders of Registrable
          Securities  participating  in the Exchange Offer or Private  Exchange,
          and which  includes  an opinion  that (i) each of the  Company and the
          Parent  has duly  authorized,  executed  and  delivered  the  Exchange
          Securities and/or Private Exchange Securities, as applicable,  and the
          related  indenture,  and  (ii)  each of the  Exchange  Securities  and
          related indenture  constitute a legal, valid and binding obligation of
          the Company and the  Parent,  enforceable  against the Company


                                       20
<PAGE>

          and the Parent in accordance with its respective terms (with customary
          exceptions).

               In the case of a Shelf  Registration  Statement,  the Company and
the Parent  may (as a  condition  to such  Holder's  participation  in the Shelf
Registration)  require each Holder of  Registrable  Securities (i) to furnish to
the  Company  and the  Parent  such  information  regarding  the  Holder and the
proposed  distribution  by such  Holder of such  Registrable  Securities  as the
Company  and the Parent  may from time to time  reasonably  request  and (ii) to
agree in writing to be bound by this  Agreement,  including the  indemnification
provisions.

               In the case of a Shelf Registration Statement, each Holder agrees
that,  upon  receipt  of any  notice  from the  Company  and the  Parent  of the
happening of any event or the discovery of any facts, each of the kind described
in  Sections  3(e)(v)  and  3(e)(viii)   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(k) hereof,  and, if so directed by
the  Company and the  Parent,  such  Holder will  deliver to the Company and the
Parent (at its  expense)  all  copies in such  Holder's  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  any of  the  Registrable  Securities  covered  by  any  Shelf
Registration  Statement  are  to  be  sold  in  an  underwritten  offering,  the
underwriter  or  underwriters  and  manager or  managers  that will  manage such
offering will be selected by the Majority Holders of such Registrable Securities
included in such offering and shall be acceptable to the Company and the Parent.
No  Holder  of  Registrable  Securities  may  participate  in  any  underwritten
registration  hereunder  unless  such  Holder (a)  agrees to sell such  Holder's
Registrable  Securities on the basis provided in any  underwriting  arrangements
approved by the persons entitled  hereunder to approve such arrangements and (b)
completes  and executes  all  questionnaires,  powers of attorney,  indemnities,
underwriting  agreements  and other  documents  required under the terms of such
underwriting arrangements.

               4. Indemnification; Contribution.

               (a) The Company and the Parent  jointly  and  severally  agree to
          indemnify and hold harmless the Initial Purchaser,  each Holder,  each
          Participating  Broker-Dealer,  each  Person  who  participates  as  an
          underwriter (any such Person being an "Underwriter")  and each Person,
          if any, who controls any Holder or  Underwriter  within the meaning of
          Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:


                                       21
<PAGE>

                    (i) against any and all loss,  liability,  claim, damage and
               expense  whatsoever,  as  incurred,  arising  out of  any  untrue
               statement  or  alleged  untrue   statement  of  a  material  fact
               contained  in any  Registration  Statement  (or any  amendment or
               supplement  thereto)  pursuant to which  Exchange  Securities  or
               Registrable  Securities  were  registered  under  the  1933  Act,
               including all documents incorporated therein by reference, or the
               omission  or  alleged  omission  therefrom  of  a  material  fact
               required to be stated therein or necessary to make the statements
               therein not misleading, or arising out of any untrue statement or
               alleged  untrue  statement  of a material  fact  contained in any
               Prospectus  (or  any  amendment  or  supplement  thereto)  or the
               omission  or  alleged  omission  therefrom  of  a  material  fact
               necessary in order to make the statements  therein,  in the light
               of the circumstances under which they were made, not misleading;

                    (ii) against any and all loss, liability,  claim, damage and
               expense whatsoever,  as incurred,  to the extent of the aggregate
               amount paid in settlement of any litigation, or any investigation
               or proceeding by any  governmental  agency or body,  commenced or
               threatened, or of any claim whatsoever based upon any such untrue
               statement or omission,  or any such alleged  untrue  statement or
               omission;  provided that (subject to Section 4(d) below) any such
               settlement  is effected  with the written  consent of the Company
               and the Parent; and

                    (iii)  against any and all expense  whatsoever,  as incurred
               (including  the fees and  disbursements  of counsel chosen by any
               indemnified   party),   reasonably   incurred  in  investigating,
               preparing   or   defending   against  any   litigation,   or  any
               investigation or proceeding by any  governmental  agency or body,
               commenced or threatened,  or any claim  whatsoever based upon any
               such untrue  statement  or omission,  or any such alleged  untrue
               statement or omission, to the extent that any such expense is not
               paid under subparagraph (i) or (ii) above;

          provided,  however,  that this indemnity  agreement shall not apply to
          any loss,  liability,  claim,  damage or expense to the extent arising
          out of any untrue statement or omission or alleged untrue statement or
          omission  made  in  reliance  upon  and  in  conformity  with  written
          information  furnished  to the  Company by the  Holder or  Underwriter
          expressly  for  use in a  Registration  Statement  (or  any  amendment
          thereto) or any Prospectus (or any amendment or supplement thereto).


                                       22
<PAGE>

               (b) Each Holder severally,  but not jointly,  agrees to indemnify
          and hold harmless the Company, the Parent, the Initial Purchaser, each
          Underwriter  and  the  other  selling  Holders,   and  each  of  their
          respective  directors  and  officers,  and each  Person,  if any,  who
          controls  the  Company,   the  Parent,  the  Initial  Purchaser,   any
          Underwriter  or any other selling Holder within the meaning of Section
          15 of the 1933 Act or Section 20 of the 1934 Act,  against any and all
          loss, liability,  claim, damage and expense described in the indemnity
          contained in Section 4(a) hereof,  as incurred,  but only with respect
          to untrue  statements or omissions,  or alleged  untrue  statements or
          omissions,  made in the Shelf Registration Statement (or any amendment
          thereto)  or any  Prospectus  included  therein (or any  amendment  or
          supplement  thereto) in reliance upon and in  conformity  with written
          information  with  respect to such Holder  furnished to the Company by
          such Holder expressly for use in the Shelf Registration  Statement (or
          any  amendment  thereto)  or  such  Prospectus  (or any  amendment  or
          supplement thereto);  provided,  however, that no such Holder shall be
          liable  for any  claims  hereunder  in  excess  of the  amount  of net
          proceeds  received  by  such  Holder  from  the  sale  of  Registrable
          Securities pursuant to such Shelf Registration Statement.

               (c) Each  indemnified  party  shall give  notice as  promptly  as
          reasonably  practicable  to each  indemnifying  party of any action or
          proceeding  commenced  against it in respect of which indemnity may be
          sought hereunder, but failure so to notify an indemnifying party shall
          not relieve such  indemnifying  party from any liability  hereunder to
          the extent it is not materially  prejudiced as a result thereof and in
          any event  shall not relieve it from any  liability  which it may have
          otherwise than on account of this indemnity agreement. An indemnifying
          party  may  participate  at its own  expense  in the  defense  of such
          action;  provided,  however,  that counsel to the  indemnifying  party
          shall not (except with the consent of the  indemnified  party) also be
          counsel to the indemnified  party. In no event shall the  indemnifying
          party or parties be liable for the fees and  expenses of more than one
          counsel (in  addition to any local  counsel)  separate  from their own
          counsel for all indemnified  parties 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.  In
          addition,  the indemnifying  party shall be entitled to, to the extent
          that it wishes, jointly with any other similarly notified indemnifying
          party, to assume the defense of any claim or action brought against an
          indemnified  party  with  counsel   reasonably   satisfactory  to  the
          indemnified  party.  After notice from the  indemnifying  party to the
          indemnified  party of its election to assume the defense of such claim
          or  action,  the  indemnifying  party  shall  not  be  liable  to  the
          indemnified party under this Section 7 for any legal or other expenses


                                       23
<PAGE>

          subsequently  incurred by the indemnified party in connection with the
          defense  thereof  other  than  reasonable   costs  of   investigation;
          provided,  however, that the Initial Purchaser shall have the right to
          employ one counsel to represent  it and its  officers,  employees  and
          controlling persons who may be subject to liability arising out of any
          claim in  respect  of which  indemnity  may be sought  by the  Initial
          Purchaser  against the Company and the Parent under this Section 4 if,
          in the reasonable judgment of the Initial Purchaser,  either (i) there
          is an actual or potential conflict between the position of the Company
          and the Parent on the one hand and the Initial  Purchaser on the other
          hand or (ii) there may be  defenses  available  to it or them that are
          different  from or  additional  to those  available to the Company and
          Parent (in any of which events the Company shall not have the right to
          direct the defense of such  action on behalf of the Initial  Purchaser
          with respect to such different defenses),  in any of which events such
          reasonable fees and expenses shall be borne by the Company and Parent.
          No indemnifying party shall,  without the prior written consent of the
          indemnified  parties,  settle or compromise or consent to the entry of
          any judgment with respect to any litigation,  or any  investigation or
          proceeding  by  any   governmental   agency  or  body,   commenced  or
          threatened,   or  any   claim   whatsoever   in   respect   of   which
          indemnification  or contribution  could be sought under this Section 4
          (whether  or not the  indemnified  parties  are  actual  or  potential
          parties  thereto),  unless such settlement,  compromise or consent (i)
          includes an unconditional  release of each indemnified  party from all
          liability arising out of such litigation, investigation, proceeding or
          claim and (ii) does not include a statement  as to or an  admission of
          fault,  culpability  or a  failure  to  act  by or on  behalf  of  any
          indemnified party.

               (d) If at any time an  indemnified  party shall have requested an
          indemnifying  party to reimburse  the  indemnified  party for fees and
          expenses of counsel,  such indemnifying  party agrees that it shall be
          liable  for any  settlement  of the  nature  contemplated  by  Section
          4(a)(ii)  effected  without its written consent if (i) such settlement
          is entered into more than 45 days after  receipt by such  indemnifying
          party of the aforesaid  request,  (ii) such  indemnifying  party shall
          have received  notice of the terms of such settlement at least 30 days
          prior  to  such   settlement   being   entered  into  and  (iii)  such
          indemnifying party shall not have reimbursed such indemnified party in
          accordance with such request prior to the date of such settlement.

               (e) If the indemnification  provided for in this Section 4 is for
          any  reason  unavailable  to  or  insufficient  to  hold  harmless  an
          indemnified  party in  respect  of any  losses,  liabilities,  claims,
          damages or expenses referred to therein,  then each indemnifying party
          shall contribute to the aggregate amount of such


                                       24
<PAGE>

          losses,  liabilities,  claims,  damages and expenses  incurred by such
          indemnified  party, as incurred,  in such proportion as is appropriate
          to reflect the relative fault of the Company and the Parent on the one
          hand and the Holders and the  Initial  Purchaser  on the other hand in
          connection  with the  statements or omissions  which  resulted in such
          losses, liabilities, claims, damages or expenses, as well as any other
          relevant equitable considerations.

               The relative  fault of the Company and the Parent on the one hand
and the Holders and the Initial  Purchaser on the other hand shall be determined
by reference to, among other things,  whether any such untrue or alleged  untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information  supplied by the Company, the Parent, the Holders or
the Initial  Purchaser and the parties'  relative intent,  knowledge,  access to
information and opportunity to correct or prevent such statement or omission.

               The Company,  the Parent,  the Holders and the Initial  Purchaser
agree that it would not be just and equitable if  contribution  pursuant to this
Section 4 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 in this Section 4. The aggregate amount of losses, liabilities, claims,
damages and expenses  incurred by an indemnified  party and referred to above in
this Section 4 shall be deemed to include any legal or other expenses reasonably
incurred by such  indemnified  party in  investigating,  preparing  or defending
against any litigation,  or any  investigation or proceeding by any governmental
agency or body, commenced or threatened,  or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

               Notwithstanding  the  provisions  of this  Section 4, the Initial
Purchaser shall not be required to contribute any amount in excess of the amount
by which the total price at which the Securities sold by it were offered exceeds
the  amount of any  damages  which the  Initial  Purchaser  has  otherwise  been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.

               No Person  guilty of  fraudulent  misrepresentation  (within  the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

               For purposes of this Section 4, each Person, if any, who controls
the Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act shall have the same rights to  contribution as the
Initial  Purchaser or Holder,  and each director of the Company,  the Parent and
each Person, if any, who controls the


                                       25
<PAGE>

Company  or the  Parent  within  the  meaning  of  Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall  have the same  rights to  contribution  as the
Company and the Parent.

               5. Miscellaneous.

               5.1 Rule 144 and Rule 144A.  For so long as the Parent is subject
to the  reporting  requirements  of Section 13 or 15 of the 1934 Act, the Parent
covenants  that it will file the  reports  required  to be filed by it under the
1933  Act and  Section  13(a)  or  15(d)  of the  1934  Act and  the  rules  and
regulations  adopted  by the  SEC  thereunder.  If the  Parent  ceases  to be so
required  to file  such  reports,  the  Parent  covenants  that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information  as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, (b) deliver such information to a prospective  purchaser as is necessary to
permit  sales  pursuant  to Rule  144A  under the 1933 Act and it will take such
further action as any Holder of Registrable  Securities may reasonably  request,
and (c) take such further  action that is  reasonable in the  circumstances,  in
each case,  to the extent  required  from time to time to enable  such Holder to
sell its Registrable  Securities without  registration under the 1933 Act within
the limitation of the exemptions provided by (i) Rule 144 under the 1933 Act, as
such Rule may be amended  from time to time,  (ii) Rule 144A under the 1933 Act,
as such Rule may be amended  from time to time,  or (iii) any  similar  rules or
regulations  hereafter  adopted  by the SEC.  Upon the  request of any Holder of
Registrable  Securities,  the  Parent  will  deliver  to such  Holder a  written
statement  as to whether it has  complied  with such  requirements.  The Company
shall not be subject to the requirements of this Section 5.1, provided, that, it
obtains no-action relief from the SEC regarding its reporting requirements under
Section 13 or 15 of the 1934 Act and under the 1933 Act.

               5.2 No  Inconsistent  Agreements.  Neither  the  Company  nor the
Parent has  entered  into and  neither the Company nor the Parent will after the
date of this Agreement 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 and will not for the term of this Agreement in any way
conflict with the rights granted to the holders of the Company's or the Parent's
other issued and outstanding securities under any such agreements.

               5.3  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 and the Parent  have  obtained  the written
consent of Holders of at least a majority in aggregate  principal  amount of the
outstanding  Registrable  Securities  affected by such amendment,  modification,
supplement, waiver or departure.


                                       26
<PAGE>

               5.4 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 (a) if to a Holder, at the most current address given by such Holder to
the  Company or the  Parent,  as the case may be, by means of a notice  given in
accordance  with the provisions of this Section 5.4, which address  initially is
the  address set forth in the  Purchase  Agreement  with  respect to the Initial
Purchaser;  (b) if to the Company,  initially at the Company's address set forth
in the Purchase Agreement,  and thereafter at such other address of which notice
is given in accordance with the provisions of this Section 5.4 and (c) if to the
Parent,  initially at the Parent's address set forth in Purchase Agreement,  and
thereafter at such other address of which notice is given in accordance with the
provisions of this Section 5.4.

               All such notices and communications  shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; two 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
under the Indenture, at the address specified in such Indenture.

               5.5  Successor  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 or the Indenture.
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, including the restrictions on resale set forth in this Agreement
and, if applicable, the Purchase Agreement, and such person shall be entitled to
receive the benefits hereof.

               5.6 Third Party Beneficiaries. The Initial Purchaser (even if the
Initial  Purchaser is not a Holder of Registrable  Securities)  shall be a third
party  beneficiary to the agreements made hereunder  between the Company and the
Parent, on the one hand, and the Holders,  on the other hand, and shall have the
right  to  enforce  such  agreements  directly  to the  extent  they  deem  such
enforcement  necessary  or  advisable  to protect  their rights or the rights of
Holders hereunder. Each Holder of Registrable Securities shall be a


                                       27
<PAGE>

third party beneficiary to the agreements made hereunder between the Company and
the Parent, on the one hand, and the Initial  Purchaser,  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 hereunder.

               5.7.   Specific   Enforcement.   Without  limiting  the  remedies
available to the Initial  Purchaser and the Holders,  the Company and the Parent
acknowledge  that any  failure by the  Company and the Parent to comply with its
obligations  under  Sections  2.1  through  2.4 hereof  may  result in  material
irreparable injury to the Initial Purchaser or the Holders for which there is no
adequate  remedy at law,  that it would not be possible  to measure  damages for
such injuries precisely and that, in the event of any such failure,  the Initial
Purchaser  or  any  Holder  may  obtain  such  relief  as  may  be  required  to
specifically  enforce  the  obligations  of the  Company  and the  Parent  under
Sections 2.1 through 2.4 hereof.

               5.8.  Restriction  on Resales.  Until the expiration of two years
after the original  issuance of the Securities and the related  guarantees,  the
Company and the Parent will not, and will cause their "affiliates" (as such term
is defined in Rule  144(a)(1)  under the 1933 Act) not to, resell any Securities
and  related  guarantees  which  are  "restricted  securities"  (as such term is
defined under Rule  144(a)(3)  under the 1933 Act) that have been  reacquired by
any of them and shall  immediately  upon any purchase of any such Securities and
related  guarantees submit such Securities and related guarantees to the Trustee
for cancellation.

               5.9 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 agreement.

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

               5.11  GOVERNING  LAW.  THIS  AGREEMENT  SHALL BE  GOVERNED BY AND
CONSTRUED IN ACCORDANCE  WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICT OF LAWS THEREOF.

               5.12  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

                           Form of Opinion of Counsel


Merrill Lynch, Pierce, Fenner & Smith
                Incorporated
Merrill Lynch World Headquarters
North Tower
World Financial Center
New York, New York 10281-1209

Ladies and Gentlemen:

               We have acted as counsel for Alliant  Energy  Resources,  Inc., a
Wisconsin  corporation  (the  "Company"),  and  Alliant  Energy  Corporation,  a
Wisconsin corporation (the "Parent"), in connection with the sale by the Company
to the Initial  Purchaser  (as defined  below) of 5,166,052 (or 5,940,960 if the
over-allotment  option is exercised in full) Exchangeable  Senior Notes Due 2030
of the Company  pursuant to the Purchase  Agreement  dated January 26, 2000 (the
"Purchase  Agreement")  among the Company,  the Parent, as guarantor and Merrill
Lynch,  Pierce,  Fenner & Smith  Incorporated (the "Initial  Purchaser") and the
filing by the Company and the Parent of an Exchange Offer Registration Statement
(the  "Registration  Statement")  in  connection  with an  Exchange  Offer to be
effected pursuant to the Registration Rights Agreement (the "Registration Rights
Agreement"),  dated  February  1, 2000  among the  Company,  the  Parent and the
Initial Purchaser.  This opinion is furnished to you pursuant to Section 3(f)(B)
of  the  Registration   Rights  Agreement.   Unless  otherwise  defined  herein,
capitalized  terms used in this  opinion  that are  defined in the  Registration
Rights Agreement are used herein as so defined.

               We have examined such documents, records and matters of law as we
have deemed  necessary for purposes of this opinion.  In rendering this opinion,
as to all  matters  of fact  relevant  to this  opinion,  we  have  assumed  the
completeness  and accuracy of, and are relying solely upon, the  representations
and warranties of the Company and the Parent set forth in the Purchase Agreement
and the statements set forth in certificates of public officials and officers of
the Company and the Parent,  without  making any  independent  investigation  or
inquiry with respect to the  completeness  or accuracy of such  representations,
warranties  or   statements,   other  than  a  review  of  the   certificate  of
incorporation, by-laws and relevant minute books of the Company and the Parent.

<PAGE>

               Based on and  subject  to the  foregoing,  we are of the  opinion
that:

               1. The Exchange Offer  Registration  Statement and the Prospectus
(other  than the  financial  statements,  notes or  schedules  thereto and other
financial  and  statistical   data  and  supplemental   schedules   included  or
incorporated by reference  therein or omitted  therefrom and the Form T-1, as to
which such counsel  need express no opinion),  comply as to form in all material
respects  with the  requirements  of the 1933 Act and the  applicable  rules and
regulations promulgated under the 1933 Act.

               We  have  participated  in the  preparation  of the  Registration
Statement and the Prospectus and in the course thereof have had discussions with
representatives of the Underwriters,  officers and other  representatives of the
Company,  the Parent and Arthur Andersen LLP, the independent  certified  public
accountants  of the  Company and the Parent,  during  which the  contents of the
Registration Statement and the Prospectus were discussed.  We have not, however,
independently  verified  and  are  not  passing  upon,  and  do not  assume  any
responsibility  for, the accuracy,  completeness  or fairness of the  statements
contained  in the  Registration  Statement  and  the  Prospectus.  Based  on our
participation as described  above,  nothing has come to our attention that would
lead us to  believe  that  the  Registration  Statement  (except  for  financial
statements  and schedules  and other  financial  and  statistical  data included
therein as to which we make no  statement)  contained  an untrue  statement of a
material fact or omitted to state a material fact required to be stated  therein
or  necessary  to make  the  statements  therein  not  misleading  or  that  the
Prospectus  or  any  amendment  or  supplement  thereto  (except  for  financial
statements  and schedules  and other  financial  and  statistical  data included
therein,  as to which  such  counsel  need make no  statement),  at the time the
Prospectus was issued,  at the time any such amended or supplemented  Prospectus
was issued or at the Closing Time, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading.

               This opinion is being furnished to you solely for your benefit in
connection  with  the  transactions  contemplated  by  the  Registration  Rights
Agreement,  and may not be used for any  other  purpose  or  relied  upon by any
person  other than you.  Except with our prior  written  consent,  the  opinions
herein expressed are not to be used, circulated, quoted or otherwise referred to
in  connection  with any  transactions  other  than  those  contemplated  by the
Registration Rights Agreement by or to any other person.

                                         Very truly yours,



                                       2
