10. The amount of terms of any Alliant  Energy  indebtedness  issued  during the
quarter.

ANSWER:

Alliant Energy  Resources (AER) issued  $300,000,000 in senior  unsecured notes,
fully and unconditionally  guaranteed by Alliant Energy  Corporation,  which was
priced on November 9, 2001 for settlement on November 15, 2001. The notes mature
on December 1, 2011 and carry a 7% coupon, having been priced at a spread of 275
basis  points  over the U.S.  Treasury  5% notes  due  August  15,  2011  (CUSIP
9128277B2)  serving as the maturity benchmark issue. The notes rank equally with
AER's  senior  unsecured  indebtedness  and were  assigned  a rating  of BBB+ by
Standard & Poor's Ratings Service and Baa1 by Moody's Investor's  Service,  Inc.
The  notes  are  redeemable  at  AER's  option  and do not have a  sinking  fund
provision.


11.  The  amount  and  terms of any  financings  consummated  by any  Nonutility
Subsidiary that is not exempt under rule 52.

12. The  notational  amount and  principal  terms of any Interest Rate Hedges or
Anticipatory  Hedges  entered  into during the  quarter and the  identity of the
other parties to the transaction.

Alliant  Energy  Resources  (AER)  entered  into  $250  million  face  value  of
Anticipatory Hedges in advance of pricing its issuance of $300 million in senior
unsecured  notes,  detailed in the answer to Item 10 above.  Five  Treasury lock
transactions were entered into:

First Union      10-31-01     $ 50 Mill.   4.3085%   11-09-01     4.267%    0.0805%
First Union      10-31-01     $ 50 Mill.   4.2700%   11-09-01     4.267%    0.0420%
Merrill Lynch    10-31-01     $ 50 Mill.   4.2800%   11-09-01     4.267%    0.0410%


Both counterparties qualified as Approved Counterparties.

The objective was to mitigate the underlying  interest rate  volatility  between
the date AER  committed  to  proceed  to  market  and the  date AER  priced  the
transaction, as is illustrated by the range of yields during the two days during
which the hedges were  layered  in. It was not certain  whether or not the issue
would be closed at the top end of the target range of $250 to $300  million,  so
the  amount  hedged  was the  lower  end of that  range.  The net  effect of the
Anticipatory  Hedges was to provide an average hedged  Treasury yield of 4.3611%
on $250 million of the debt issue.

The choice of Treasury locks over the alternative forward-starting interest rate
swaps,  which  would  have  hedged an element  of the  spread of  Treasury,  was
predicated on the  comparative  efficiency of the two  alternatives.  The spread
over  Treasury  for  comparable  issues was quite  volatile,  in part due to the
record volume of corporate  debt being issued and specific  corporate  events in
the  industry  sector.  The  LIBOR-Treasury  correlation  (which  impacts on the
hedging efficiency of a forward-starting interest rate swap) was not as tight as
it  had  been  historically.  In the  event,  the  hedges  qualified  for  hedge
accounting treatment under U.S. GAAP and FAS 133 guidelines.
