PROSPECTUS

                                  $750,000,000

                               Mirant Corporation
                                 ---------------

                   2.5% Convertible Senior Debentures due 2021
                                       and
                                  Common Stock
                                 ---------------

                                  THE OFFERING
    This prospectus relates to up to $750,000,000 in aggregate  principal amount
of 2.5%  Convertible  Senior  Debentures due 2021, which may be offered and sold
from time to time by certain of the  securityholders  of Mirant  Corporation and
its  Subsidiaries  ("Mirant,"  "we" or  "us"),  all of whom  are  named  in this
prospectus. We issued the debentures in a private placement at an issue price of
$1,000  per  debenture  (100% of the  principal  amount  at  maturity).  Selling
securityholders  will use this  prospectus  to resell their  debentures  and the
shares  of  common  stock  issuable  upon  conversion  or  redemption  of  their
debentures at fixed prices, which may be changed, at prevailing market prices at
the  time of  sale,  at  varying  prices  determined  at the  time of sale or at
negotiated prices.

    We will not receive any of the proceeds from the sale of the debentures. The
selling  securityholders may offer the debentures and the shares of common stock
issuable upon their conversion through public or private transactions, on or off
the New York Stock  Exchange,  at  prevailing  market  prices,  or at  privately
negotiated  prices.  All  costs,  expenses  and  fees  in  connection  with  the
registration of the debentures will be borne by us.

                                 THE DEBENTURES
    The  debentures  are senior debt  securities.  The debentures are our senior
unsecured  obligations  and rank  equally  with all of our  existing  and future
senior unsecured indebtedness.  The debentures mature on June 15, 2021. Interest
on the  debentures  at the  rate of 2.5%  per year on the  principal  amount  is
payable  semiannually  in  arrears  on June  15 and  December  15 of each  year,
beginning December 15, 2001. We will pay additional  interest in the event of an
upward interest adjustment as described below.

    We may redeem for cash some or all of the debentures at any time on or after
June 18, 2006 at a price equal to 100% of the principal amount of the debentures
to be redeemed plus accrued and unpaid interest to the redemption date.

    Holders may convert their debentures into 14.7167 shares of our common stock
(subject  to  adjustment)  for  each  $1,000   principal  amount  of  debentures
(equivalent  to an initial  conversion  price of $67.95  per share  based on the
issue price of the  debentures)  under any of the following  circumstances:  (i)
during any  conversion  period (as  defined in this  prospectus)  if the closing
sales  prices  of our  common  stock  for at  least  20  trading  days in the 30
consecutive  trading days ending on the first day of such  conversion  period is
more than 110% of the accreted conversion price per share of common stock on the
first day of the conversion period;  (ii) if the debentures have been called for
redemption;  or (iii) upon the occurrence of specified  corporate  transactions.
The  conversion  rate may be  adjusted  as  described  in this  prospectus.  The
"accreted  conversion  price"  as of any day will  equal  100% of the  principal
amount of the debenture plus accrued and unpaid interest  (excluding any accrued
and unpaid interest payable as cash interest),  if any, divided by the number of
shares of our common stock  issuable upon  conversion of such  debenture on that
day.

    The interest rate on the  debentures  will be 2.5% per year through June 15,
2004. If the average of the closing sales price of our common stock is less than
or equal to 45% of the accreted  conversion  price of the  debentures for any 20
out of the last 30  trading  days  ending  five  days  prior to each June 15 and
December 15 beginning on June 15, 2004, then the interest rate on the debentures
will be  subject  to an upward  interest  adjustment  to the reset  rate for the
subsequent  six-month period. The upward interest  adjustment will result in the
interest rate on the debentures  being equivalent to the per year reset rate (as
defined in this prospectus). If an upward interest adjustment is in effect for a
particular six-month period, we will pay a portion of the interest adjustment as
cash interest at a rate of 0.25% per year (0.125% per  six-month  period) of the
principal amount,  plus accrued and unpaid interest  (excluding interest payable
in cash), and the remaining  additional  interest will be accrued and payable at
maturity.  Following a tax event as defined herein, we may elect to pay interest
entirely in cash. After June 15, 2004, if the average of the closing sales price
of our common stock is not less than or equal to 45% of the accreted  conversion
price  of the  debentures  for  any 20 out of the  last 30  trading  days of the
six-month period ending on the fifth day preceding each June 15 and December 15,
then the interest rate on the  debentures for the  subsequent  six-month  period
will revert to 2.5% per year.  For United  States  federal  income tax purposes,
holders  will be required to treat the  debentures  as  contingent  payment debt
instruments.  You should read the  discussion of certain  United States  federal
income tax consequences relevant to the debentures beginning on page 30.

    Holders may require us to purchase all or a portion of their  debentures  on
June 15, 2004,  June 15, 2006,  June 15, 2011 and June 15, 2016 at a price equal
to 100% of the principal  amount of the  debentures to be purchased plus accrued
and unpaid  interest to such  purchase  date.  We may choose to pay the purchase
price in cash, shares of our common stock or a combination of cash and shares of
our common stock.

    Holders  may  also  require  us to  purchase  debentures  for  cash  upon  a
Fundamental Change (as defined in this prospectus) involving Mirant. In the case
of a purchase upon a  Fundamental  Change,  the purchase  price will be equal to
100% of the principal amount of the debentures plus accrued and unpaid interest.

    We do not intend to list the debentures on any national  securities exchange
or automated  quotation  system.  The  debentures and the shares of common stock
issuable  upon  conversion  of the  debentures  issued  in the  initial  private
placement are eligible for trading in the Private Offerings, Resales and Trading
through  Automated  Linkages Market,  commonly referred to as the PORTAL Market.
The debentures  and the shares of common stock  issuable upon  conversion of the
debentures sold using this prospectus,  however,  will no longer be eligible for
trading in the PORTAL system.

    Our common stock is listed on the New York Stock  Exchange  under the symbol
"MIR." On October 3, 2001,  the last  reported sale price of our common stock on
the New York Stock Exchange was $25.63 per share.

selling securityholder sells securities,  the selling securityholder is required
to provide you with this prospectus, and, in some cases, a prospectus supplement
containing specific  information about the selling  securityholder and the terms
of the  securities  being  offered.  That  prospectus  supplement  may include a
discussion  of any risk factors or other  special  considerations  applicable to
those  securities.  Any  prospectus  supplement  may also add,  update or change
information  in this  prospectus.  If there  is any  inconsistency  between  the

The Power and Gas Markets

    In the United  States,  during 2000, the Energy  Information  Administration
estimates that the power industry had an end-user market of over $228 billion of
electricity  sales  produced by an aggregate base power  generation  capacity of
approximately  793,000 MW (North American Electric  Reliability Council ("NERC")
2001 Summer Assessment).  The NERC anticipates that near term electricity demand
will grow by 60,500 MW in the  period  from  2000-2004  (Reliability  Assessment
2000-2009: The Reliability of Bulk Electric Systems in North America).

    Historically,  the  power  generation  industry  has been  characterized  by
electric utility monopolies selling to a franchise customer base. In response to
increasing  customer  demand for access to  low-cost  electricity  and  enhanced
services,  new regulatory initiatives have been and are continuing to be adopted
to increase competition in the power industry.  As a result of the recent energy
crisis  in  California,   some  states  have  either   discontinued  or  delayed
implementation  of initiatives  involving retail  deregulation.  In deregulating
markets,  industry trends and regulatory  initiatives are transforming  existing
franchise  customer markets,  which are characterized by vertically  integrated,
price-regulated  utilities,  into markets in which generators  compete with each
other  for  their  principal  customers  (wholesale  power  suppliers  and major
end-users) on the basis of price, service quality and other factors.

    During  the late  1980s and early  1990s  deregulation  of the  natural  gas
markets  created  a robust  competitive  wholesale  gas  market.  Gas  demand is
expected to grow from 23  trillion  cubic feet per year in 2000 to a 30 trillion
cubic feet per year by 2010.  The majority of this growth is being driven by the
electric  generation market. The competitive  electric  generation market favors
low cost generation  technologies such as natural gas-fired  combustion turbines
or combined  cycle  plants to serve  growing  electricity  demand and to replace
older, less efficient units. Additionally,  natural gas continues to be the most
cost  effective  fuel  source  that  meets  increasingly   stringent  clean  air
requirements.  Currently,  16% of US power  generation is fueled by natural gas.
Cambridge  Energy  Research  Associates  estimates  that there are 240,000 MW of
proposed power generation development over the next four years in North America.
Of this total,  90% is expected to use natural gas as its primary energy source.
While  the  likelihood  that all the  proposed  additions  will  actually  enter
commercial  service as scheduled is low, it does appear  likely that natural gas
demand driven by power generation will be significant. Consequently, the natural
gas and power commodity markets are converging rapidly. The converging power and
gas markets could create significant arbitrage opportunities for Mirant as a top
five  marketer  of  natural  gas  and  power  and an  owner  and  controller  of
significant gas and power assets.

     We view  our  gas  and  power  marketing  and  risk  management  and  power
generation  businesses  as an  integrated  unit.  As the  natural  gas and power
markets  continue to  deregulate,  unbundle  and  converge,  we believe that our
marketing experience,  risk management  capabilities and products and control of
selected assets in both commodities  potentially afford us a wide range of value
creation  opportunities  which  could  benefit  both us and our  customers.  The
ongoing  restructuring  of the  power  industry  should  continue  to  transform
traditional   vertically   integrated,   price-regulated   markets   into   more
competitive, more volatile markets. This transformation requires that generators
and their  principal  customers  manage the risks  associated with producing and
delivering  energy  commodities.  As such,  this  transformation  of the  energy
markets could have the effect of creating opportunities for us to market  energy
                                       5


commodities  and provide  services to manage  these  risks.  We believe the move
towards  competitive   marketplaces  will  increase  in  the  U.S.  and  abroad,
potentially  providing  additional   opportunities  for  us  to  grow  our  risk
management business.

    Outside  of the United  States,  we expect  many  governments  in  developed
economies to privatize their utilities, having realized that their energy assets
can be sold to raise capital without  impairing  system  reliability.  We expect
these countries to develop regulatory structures to encourage competition in the
electricity  sector.  In developing  countries,  the demand for  electricity  is
expected  to grow  rapidly.  In order to satisfy  this  anticipated  increase in
demand,  some developing  countries have adopted government programs designed to
encourage  private  investment  in power  plants.  We believe  that these market
trends will  continue  to create  opportunities  to acquire  and  develop  power
generation plants outside the United States.

Strategy

    Our strategy is to expand our business through ownership, leasing or control
of  additional  natural gas and  electricity  assets and to  continue  our rapid
growth by capitalizing on opportunities in markets where our unique  combination
of strengths in physical asset management, electricity generation, management of
gas assets and energy  marketing and risk  management  services  allows us to be
positioned  as a  leading  provider  of energy  products  and  services.  We are
implementing   our  strategy   through  the  development  of  new  power  plants
(greenfield  projects),  the  expansion  of existing  power  plants  (brownfield
projects),  acquisitions of power and gas assets competitively positioned in our
targeted  markets,  contractual  arrangements  for  the  control  of  generation
capacity and gas management facilities,  the expansion of our marketing and risk
management  activities  and the  implementation  of  information  technology and
e-commerce applications. We continually review acquisition opportunities and are
currently  in  discussions  with a number of  parties  in  regard  to  potential
acquisitions,  including  potential  acquisitions in the U.S. that may be deemed
material to our business.  Our willingness to pursue these  opportunities may be
dependent on many  factors,  including,  but not limited to, the market price of
our common stock. To secure wholesale supply agreements or to provide additional
opportunities for growth,  profitability or revenue stability, we may enter into
agreements to acquire,  control or manage  distribution and supply businesses or
other  energy  aggregators  in  selected  markets.  We expect to fund our growth
strategy in both the long and  short-term  through a  combination  of cash flows
from  operations  as well as debt  financings  and  equity  offerings  that  are
currently under evaluation.

    While we believe that our experience and expertise in assessing and managing
market and credit risk will allow us to remain  competitive  during  volatile or
otherwise  adverse  market  circumstances,  we may suffer from some  competitive
disadvantages which impede our ability to implement this strategy.

Competition

    As a global competitive energy company,  we face intense  competition in all
phases of the  business  in which we compete,  both in the United  States and in
international  markets.  We encounter  competition  from companies of all sizes,
having varying levels of experience, financial and human resources and differing
strategies.  In the power generation  markets, we compete in the development and
operation of  energy-producing  projects,  and our  competitors in this business
include various utilities,  industrial companies and independent power producers
(including affiliates of utilities). In our energy marketing and risk management
operations,  we compete with  international,  national and regional full service
energy providers, merchants, producers and pipelines in our ability to aggregate
competitively  priced  supplies  from a variety of sources and  locations and to
utilize efficient transmission or transportation.

    The  following  summarizes  our  competitive  position in several of our key
markets:

    o   North  America:   We  were  ranked  the  fifth  and  the  sixth  largest
        competitive  power  company  in July 2001 and July  2000,  respectively,
        according to the Platts  "Global  Power  Report." In  addition,  for the
        second  quarter of 2001,  our marketing and risk  management  operations
        were  ranked  by Power  Markets  Weekly  as the  seventh  largest  North
        American  power  marketer  and by Gas Daily as the third  largest  North
        American gas marketer.

    o   Europe: In the European market, in general, we were ranked among the top
        10 largest  private power  company  based on total  dollars  invested in
        private power assets according to Cambridge Energy Research  Associates.
        In  addition,  according  to 1999  data,  Bewag  was the  sixth  largest
        electricity  producer  in  Germany  based  on  total  electricity  sales
        (approximately  13 TWh). These rankings are based on a report by VDEW, a
        German electricity association.

    o   Asia-Pacific:  As of July  2001,  we  ranked  sixth in the  Asia-Pacific
        market among the twenty largest  private power companies and we were the
        second  largest U.S.  developer as measured by MW's of equity  ownership
        according to Cambridge Energy Research Associates. Specifically, we have
        an  approximate  20%  share  of  the  total  installed  capacity  in the
        Philippines,  and we are the largest private  producer of electricity in
        that country.  In general,  our coal-fired plants in the Philippines are
        among the lowest operating cost plants in their market and have exceeded
        their contractual  availability  requirements.  In addition we also hold
        interests  in  power  plants  located  in  the  Guangdong  and  Shandong
        provinces of China.
                                       6


    During the transition of the energy industry to competitive  markets,  it is
difficult  for us to assess our position  versus the position of existing  power
providers and new entrants.  Due to the fact that each company may employ widely
differing  strategies in their fuel supply and power sales contracts with regard
to pricing,  terms and conditions.  Further  difficulties in making  competitive
assessments  of our company  arise from the fact that many states and  countries
are considering or implementing  different types of regulatory and privatization
initiatives  that are aimed at  increasing  competition  in the power  industry.
Increased  competition  that has  resulted  from some of these  initiatives  has
already  contributed  to a reduction in  electricity  prices and put pressure on
electric  utilities  to lower  their  costs,  including  the  cost of  purchased
electricity. Additionally, our business is rapidly becoming more competitive due
to technological  advances in power generation,  e-commerce enabling new ways of
conducting business,  the increased role of full service providers and increased
efficiency of energy markets.

    In  general,  however,  we believe  that our  experience  and  expertise  in
assessing  and  managing  market  and  credit  risk  will  allow  us  to  remain
competitive during volatile or otherwise adverse market circumstances.

Recent Developments

    In  addition  to the recent  developments  described  below,  please see our
Annual  Report on Form 10-K for the year ended  December 31, 2000, as amended by
Form 10-K/A,  our Quarterly  Report on Form 10-Q for the three months ended June
30, 2001, as amended by Form 10-Q/A,  and our Quarterly  Report on Form 10-Q for
the three months  ended March 31, 2001 and our Forms 8-K filed on September  17,
2001 and on  October  3,  2001,  which are  incorporated  by  reference  in this
prospectus.

    In January  2001,  the EPA,  Region 3 issued a request  for  information  to
Mirant  Mid-Atlantic  concerning the air permitting  implications of past repair
and maintenance activities at the Chalk Point, Dickerson, Morgantown and Potomac
River plants. Mirant Mid-Atlantic has responded fully to this request.

    On September 20, 2001,  Pacific Gas and Electric  Company filed its proposed
plan of  reorganization  with the bankruptcy court. If the terms of the plan are
confirmed,  its large  unsecured  creditors  would  receive 60% of their allowed
claims in cash within a few months following confirmation, with the remainder to
be paid in negotiable debt with terms from ten to thirty years.

    On  September  21,  2001,  the  defendants  in  the  California  rate  payer
litigation  served upon the  plaintiffs in each case a Joint  Demurrer,  a Joint
Motion to Strike and a Joint Motion to Stay. The Joint Demurrer asserts that the
defendants  should be granted judgment as a matter of law on the claims asserted
by the plaintiffs. The Joint Motion to Strike asserts that if the court does not
conclude that plaintiffs'  claims are barred  entirely,  then all claims seeking
monetary recovery should be stricken based on the filed rate doctrine. The Joint
Motion to Stay  asserts  that any claims not  dismissed in response to the Joint
Demurrer or stricken in response to the Motion to Strike  should be stayed until
the FERC has entered a final order in the ongoing  proceedings before it related
to the investigations of the California wholesale markets.  These pleadings have
been  served  on the  plaintiffs  in each of the six cases but will not be filed
with the court  until a  determination  is made  regarding  whether  the actions
should be coordinated  and, if so, before which court.  The  plaintiffs  seek to
have the cases coordinated before a court in San Francisco, while the defendants
have  asked for the cases to be  coordinated  before a court in San  Diego.  The
California  Judicial Council has sent the coordination  motions to the presiding
judge for the  Superior  Court for the County of San Diego,  who has  assigned a
judge to hear the  coordination  petitions.  The judge will  decide  whether the
cases should be coordinated and, if so, before what court. We cannot predict the
outcome of these cases.

    On September 26, 2001, we announced that the partnership discussions related
to the possible  combination of Bewag,  VEAG, Laubag and HEW, the so-called Neue
Kraft,  were terminated.  We continue to own approximately 45% of the integrated
utility, Bewag, which serves the city of Berlin.

    In the July 25 order issued in the California  refund  proceeding,  the FERC
also  ordered that a  preliminary  evidentiary  proceeding  be held to develop a
factual  record on whether there have been unjust and  unreasonable  charges for
spot market  bilateral  sales in the Pacific  Northwest  from  December 25, 2000
through June 20, 2001. In the  proceeding,  the  Department  of Water  Resources
("DWR")  filed to recover  certain  refunds  from  parties,  including  a Mirant
subsidiary,   for   bilateral   sales   of   electricity   to  the  DWR  at  the
California/Oregon  border,  claiming  that such sales took place in the  Pacific
Northwest.  A  FERC  administrative  law  judge  ("ALJ")  recently  concluded  a
preliminary  evidentiary  hearing related to possible refunds for power sales in

                                      7


the Pacific  Northwest.  In a preliminary  ruling issued September 24, 2001, the
ALJ indicated that he would order no refunds because the complainants had failed
to prove  any  exercise  of  market  power or that any  prices  were  unjust  or
unreasonable.  FERC may  accept or reject  this  preliminary  ruling  and FERC's
decision may itself be appealed.  At this time,  the Company  cannot predict the
outcome of this  proceeding.  If we are  required  to refund such  amounts,  our
subsidiaries would be required to refund amounts previously received pursuant to
sales made on their behalf.

    On October 2, 2001, the California  Public Utilities  Commission  refused to
approve a rate agreement  with the DWR. The  California  Treasurer has indicated
that this rate agreement is closely  related to the issuance of the proposed $13
billion in revenue bonds by the DWR that would be used by the DWR to finance the
purchase of electric energy.

    On October 9, 2001,  Mirant  Americas  Generation,  an indirect wholly owned
subsidiary of the Company,  issued $750 million in senior  unsecured notes under
Rule 144A of the Securities  Act. The notes issued included $300 million of 7.2%
senior notes due 2008 and $450  million of 8.5% senior  notes due 2021.  The net
proceeds from these notes will be used to repay the majority of existing  loans.
Interest  on the notes is payable  semiannually  beginning  April 1,  2002.  The
Company may redeem the notes,  in whole or in part,  at any time at a redemption
price  equal to 100% of the  principal  amount  plus  accrued  interest,  plus a

                                  THE OFFERING

Debentures................    $750,000,000 aggregate principal amount of 2.5%
                              convertible senior debentures due 2021.


Issue Price...............    Each debenture was initially issued at a price of
                              $1,000 per debenture and a principal amount at
                              maturity of $1,000.  Selling securityholders may
                              sell the debentures and the associated common
                              stock from time to time in one or more
                              transactions at fixed prices, which may be changed
                              at  prevailing  market prices at the time of sale,
                              at varying  prices determined at the  time of sale
                              or at negotiated prices.


Maturity of Debentures.....   June 15, 2021.


Ranking....................   The  debentures  are our senior unsecured
                              obligations and rank equally with all of our
                              existing  and  future  senior  unsecured
                              indebtedness. However,  we are a holding  company
                              and the debentures are effectively subordinated to
                              all existing and future obligations of our
                              subsidiaries.  As of June 30, 2001, we  had
                              approximately   $7,992   million   of   total
                              indebtedness  outstanding.  As of June  30,  2001,
                              our subsidiaries had approximately  $6,054 million
                              of total indebtedness.
                              See "Description of Debentures--Ranking."


Interest...................   2.5% per year on the  principal amount payable
                              semiannually  in arrears on June 15 and December
                              15 of each year,  beginning  on December 15, 2001.
                              We will pay  additional  interest in the event of
                              an upward  interest  adjustment  described  below.
                              See "Description of Debentures-- Interest."



Interest Adjustment........   The interest rate on the debentures is 2.5% per
                              year through June 15, 2004.  If the average of the
                              closing sales price of our common stock is less
                              than or equal to 45% of the accreted conversion
                              price of the debentures for any 20 out of the last
                              30 trading days ending five days prior to each
                              June 15 and December 15, as applicable, commencing
                              June 15, 2004, then the interest rate on the
                              debentures will be subject to an upward interest
                              adjustment to the applicable reset rate(as defined
                              below) for the subsequent six-month period.  If an
                              upward interest adjustment is in effect and the
                              average of the closing sales price of our common
                              stock is not less than or equal to 45% of the
                              accreted conversion price of the debentures for
                              any 20 out of the last 30 trading days of any
                              six-month period ending on the fifth day preceding
                              each June 15 and December 15, as applicable, then
                              the interest rate on the debentures for the
                              subsequent six-month period will revert to 2.5%
                              per year.  If an upward interest adjustment is in
                              effect for a particular six-month period, we will
                              pay a portion of the interest adjustment as cash
                              interest at an annualized rate of 0.25% per year
                              (0.125% per six-month period) of the principal
                              amount, plus any accrued and unpaid interest
                              (excluding interest payable in cash), and the
                              remaining interest will be accrued and payable at
                              maturity or upon the redemption or repurchase of
                              the debentures.  Following a tax event (as
                              described below), we may elect to pay interest
                              entirely in cash.


                              The  "applicable  reset  rate" for any  six-month
                              period in which there is an upward interest
                              adjustment will be set as of each of June 15,2004,
                              June 15, 2006,  June 15, 2011 and June 15, 2016
                              (each, a "purchase date") and will be equal to the
                              rate (the "reference fixed  rate") that would,  in
                              the sole and reasonable judgment of the reset rate
                              agent (as defined  in  this   prospectus) who must
                              seek  indicative reference  rates from  one  other
                              nationally recognized investment bank, result in a
                              trading  price of par for a hypothetical issue  of
                              our senior,  non-convertible, fixed-rate, callable
                              debt securities with (i) a final maturity equal to
                              the term from such purchase date until the next
                              purchase date, (ii) an aggregate principal amount
                              equal to the then principal  amount of the
                              debentures plus accrued and  unpaid  interest
                              (excluding  any  accrued  and  unpaid interest
                              payable as cash interest) and (iii)provisions that
                              are, insofar as would be practicable for an issue
                              of senior, non-convertible,  fixed-rate,  callable
                              debt  securities, substantially identical to those
                              of the debentures; provided that the reset rate
                              for the period commencing June 15, 2004 and ending
                              June 15,  2006 shall not exceed 10% per year.  If
                              the reset rate agent  determines in its reasonable
                              judgment that  there  is  no  suitable   reference
                              fixed  rate, the applicable rate of accretion  for
                              that period will be the applicable rate of
                              accretion  then in effect,  such rate of accretion
                              to remain in effect  until the reset  rate  agent
                              determines that there is a suitable  reference
                              fixed rate at which  time the  reset  rate  agent
                              shall  determine a new applicable  reset  rate for
                              the period ending  on the next purchase date.  The
                              applicable  reset rate for a debenture that is
                              subject to an upward  interest adjustment shall be
                              determined  as to any period for which  such
                              adjustment  is applicable until a new applicable
                              reset rate is in effect or until the  original
                              interest  rate is again in effect.  See
                              "Description of Debentures - Interest Adjustment."

Tax Event..................   We can elect to pay all the interest on the
                              debentures in cash upon the occurrence of a tax
                              event from and after the date a tax event occurs
                              instead of allowing that interest on the
                              debentures to accrete.  If that happens, the
                              principal amount on which we pay interest will be
                              restated and will be equal to the principal amount
                              of the debentures plus accrued and unpaid interest
                              (excluding interest payable in cash prior to our
                              election) on the date of restatement.  See
                              "Description of Debentures-- Tax Event."

Conversion Rights..........   Holders may convert their debentures into shares
                              of our common stock prior to stated maturity under
                              any of the following circumstances:

                                (i)  during any conversion period if the closing
                                     sales  price of our common  stock for a
                                     period  of at least 20 trading  days in the
                                     period of 30 consecutive trading days
                                     ending on the first  day of such conversion
                                     period is more  than  110% of the  accreted
                                     conversion price per share of common stock
                                     on the first day of the conversion  period.
                                     A conversion period will be the  period
                                     from and  including the twelfth trading day
                                     in a fiscal quarter  to but not including
                                     the twelfth trading day in the immediately
                                     following fiscal quarter; or

                               (ii)  if the debentures have been called for
                                     redemption; or

                              (iii)  upon the occurrence of specified corporate
                                     transactions described under "Description
                                     of Debentures -- Conversion Rights."

                              For each debenture surrendered for conversion, a
                              holder will  receive  14.7167 shares of our common
                              stock (subject to adjustment). This represents an
                              initial conversion  price of $67.95 per  share  of
                              common  stock Based on the  issue  price of the
                              debentures.  As described in this prospectus,  the
                              conversion    rate   may   be adjusted for certain
                              reasons, but it will  not be  adjusted for accrued
                              interest. Upon conversion, holders will not
                              receive any cash payment representing accrued  and
                              unpaid   interest.   Instead, accrued  and unpaid
                              interest will  be deemed  paid by the common stock
                              received by holders on conversion.  Debentures
                              called for redemption may be surrendered for
                              conversion   until  the close   of   business  two
                              business  days  prior  to the redemption date.

Optional Redemption........   On or after June 18, 2006, we may redeem for cash
                              all or part of the debentures at any time, upon
                              not less than 30 nor more than 60 days notice by
                              mail to holders of debentures, for a price equal
                              to 100% of the principal amount of the debentures
                              to be redeemed plus any accrued and unpaid
                              interest to the redemption date.  See"Description
                              of Debentures-- Optional Redemption."

                              circumstances. See "Description of Debentures--
                              Events of Default."



                              The following are events of default with respect
                              to the debentures:

                                  o   our  failure  for  30 days to pay when due
                                      any interest(including additional interest
                                      payable pursuant to an upward interest
                                      adjustment) on the debentures;

                                  o   our  failure  to pay the principal amount,
                                      plus accrued  and unpaid  interest  on the
                                      debentures, at maturity, upon redemption,
                                      purchase at the  option of the holder or
                                      following a Fundamental Change, when the
                                      same becomes due and payable;

                                       10


                                  o   our failure to deliver shares of our
                                      common  stock upon an appropriate election
                                      by holders of debentures to convert those
                                      debentures and continuance  of  such
                                      default for 10 days;


                                  o   our failure to comply in any material
                                      respect  with  any of our covenants or
                                      agreements  in  the debentures or the
                                      Indenture for 90 days after written notice
                                      is given by the Trustee or by the holders
                                      of at least 25% in principal amount of all
                                      outstanding debentures; and


                                  o   certain events involving the bankruptcy,
                                      insolvency or reorganization of Mirant.

Tax........................   Each holder has agreed in the Indenture, for U.S.
                              federal income tax purposes, to treat the
                              debentures as"contingent payment debt instruments"
                              and to be bound by our application of the Treasury
                              regulations that govern contingent payment debt
                              instruments, including our determination that the
                              rate at which interest will be deemed to accrue
                              for federal income tax purposes will be 8.543% per
                              year, which is the rate comparable to the rate at
                              which we could borrow on a noncontingent,
                              nonconvertible borrowing. Based on this agreement,
                              (i)each holder will be required to accrue interest
                              on a constant yield to maturity basis at that
                              rate, with the result that a holder will recognize
                              taxable income significantly in excess of cash
                              received while the debentures are outstanding, and
                              (ii) a holder will recognize ordinary income upon
                              a conversion of a debenture into our stock equal
                              to the excess, if any, between the value of the
                              stock received on the conversion and the sum of
                              the original purchase price of the holder's
                              debenture and accrued but unpaid interest.


                              The proper application of the regulations that
                              govern contingent payment debt instruments  to a
                              holder of a debenture is uncertain in a number of
                              respects,  and if our treatment were successfully
                              challenged by the Internal Revenue Service, it
                              might be determined  that, among  other
                              differences, a holder  should  have  accrued
                              interest  income  at a lower rate, should not have
                              recognized income or gain upon the conversion, and
                              should not have recognized ordinary income upon a
                              taxable  disposition  of  its debenture.


                              HOLDERS SHOULD CONSULT THEIR TAX ADVISORS
                              REGARDING  THE FEDERAL, STATE, LOCAL AND FOREIGN
                              TAX  CONSEQUENCES  OF AN  INVESTMENT IN THE
                              DEBENTURES   AND  WHETHER  AN INVESTMENT IN THE
                              DEBENTURES IS  ADVISABLE IN LIGHT OF THE AGREED
                              UPON TAX TREATMENT AND THE HOLDER'S PARTICULAR TAX
                              SITUATION.


Use of Proceeds............   We will not receive any of the proceeds from the
                              sale by the selling securityholders of the
                              debentures or the shares of common stock issuable
                              upon conversion or redemption of the debentures.


Book-Entry Form............   The debentures have been issued in book-entry form
                              and are represented by permanent a global
                              certificate deposited with, or on behalf of, DTC
                              and registered in the name of a nominee of DTC.
                              Beneficial interests in any of the debentures will
                              be shown on, and transfers will be effected only
                              through, records maintained by DTC or its nominee
                              and any such interest may not be exchanged for
                              certificated securities, except in limited
                              circumstances.  See "Description of Debentures--
                              Book-Entry System."


Trading....................   We do not intend to list the debentures on any
                              securities exchange or in any automated quotation
                              system.  The debentures issued in the initial
                              private placement are eligible for trading in the
                              PORTAL market; however, no assurance can be given
                              as to the liquidity of or trading market for the
                              debentures.  The debentures sold using this
                              prospectus, however, will not be eligible for
                              trading in the PORTAL system. Our shares of common
                              stock are traded on the New York Stock Exchange
                              under the symbol "MIR."

                                  RISK FACTORS

    Investing in the debentures  and the associated  common stock involves risk.
In order to  better  understand  the  risks  involved  in an  investment  in our
securities,  please see the risk factors  described in our Annual Report on Form
10-K for the year ended  December  31,  2000,  as amended  by Form  10-K/A,  our
Quarterly  Report on Form 10-Q for the three  months  ended  June 30,  2001,  as
amended  by Form  10-Q/A,  and our  Quarterly  Report on Form 10-Q for the three
months  ended  March 31,  2001,  which are  incorporated  by  reference  in this
prospectus.  You  should  carefully  consider  these  risks  as  well  as  other
information  contained or  incorporated  by reference in this  prospectus or any
applicable prospectus supplement before making an investment decision. The risks
and  uncertainties  described below are tailored to the risks  prescribed by the
debentures. Additional risks and uncertainties not presently known to us or that
we currently deem immaterial may also impair our business operations.

We  expect  that the  trading  value  of the  debentures  will be  significantly
affected by the price of our common stock and other factors.

    The market price of the debentures is expected to be significantly  affected
by the market price of our common stock.  This may result in greater  volatility
in the trading value of the debentures than would be expected for nonconvertible
debt securities we issue. In addition, the debentures have a number of features,
including conditions to conversion,  which, if not met, could result in a holder
receiving  less than the value of the common stock into which the debentures are
otherwise  convertible.  These features could adversely affect the value and the
trading prices for the debentures.

An active trading market for debentures may not develop.

    We cannot assure you that an active trading  market for the debentures  will
develop or as to the liquidity or sustainability of any such market, the ability
of  holders  to sell  their  debentures  or the  price at which  holders  of the
debentures will be able to sell their  debentures.  Future trading prices of the
debentures  will  depend  on  many  factors,   including,  among  other  things,
prevailing interest rates, the market for similar  securities,  the price of our
common stock, our performance and other factors.

We may not  have the  ability  to raise  the  funds  necessary  to  finance  the
Fundamental Change purchase or purchase at the option of the holder.

    On June 15, 2004,  June 15, 2006,  June 15, 2011 and June 15, 2016, and upon
the occurrence of a Fundamental Change of Mirant,  holders of the debentures may
require us to purchase their debentures.  However,  it is possible that we would
not have  sufficient  funds at that time to make the  required  purchase  of the
debentures.  In addition,  certain important corporate events, such as leveraged
recapitalizations  that would  increase the level of our  indebtedness,  may not
constitute  a  Fundamental  Change  under the  indenture.  See  "Description  of
Debentures  -- Purchase of Debentures by Mirant at the Option of the Holder" and
"-- Fundamental Change."

Our holding company structure results in structural subordination and may affect
our ability to make payments on the debentures.

    The debentures are our  obligations  exclusively.  We are a holding  company
and, accordingly,  substantially all of our operations are conducted through our
subsidiaries.  As a result,  our cash flow and our  ability to service our debt,
including  the  debentures,  depends upon the earnings of our  subsidiaries.  In
addition, we depend on the distribution of earnings,  loans or other payments by
our subsidiaries to us.

    Our subsidiaries are separate and distinct legal entities.  Our subsidiaries
have no  obligation  to pay any amounts due on the  debentures  or to provide us
with funds for our payment  obligations,  whether by  dividends,  distributions,
loans or other payments. In addition,  any payment of dividends,  distributions,
loans or advances by our  subsidiaries  to us could be subject to  statutory  or
contractual  restrictions.  Payments  to us by our  subsidiaries  will  also  be
contingent upon our subsidiaries' earnings and business considerations.

    Our right to  receive  any  assets  of any of our  subsidiaries  upon  their
liquidation  or  reorganization,  and  therefore the right of the holders of the
debentures to participate in those assets,  will be effectively  subordinated to
the  claims  of that  subsidiary's  creditors,  including  trade  creditors.  In
addition, even if we were a creditor of any of our subsidiaries, our rights as a
creditor  would be  subordinate  to any  security  interest in the assets of our
subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

                                       12



You should consider the United States federal income tax  consequences of owning
the debentures.

    While the proper tax  treatment of a holder of the  debentures is uncertain,
we and each holder  have  agreed in the  indenture  to treat the  debentures  as
"contingent  payment debt instruments" and to be bound by our application of the
Treasury  regulations that govern contingent payment debt instruments.  Pursuant
to this  agreement,  a holder will be required to accrue  interest on a constant
yield-to-maturity  basis  at a rate  comparable  to the  rate at  which we would
borrow in a  noncontingent,  nonconvertible  borrowing  (8.543%).  A holder will
recognize  taxable  income  significantly  in excess of cash received  while the
debentures are  outstanding.  In addition,  under the  indenture,  a holder will
recognize  ordinary  income,  if  any,  upon a  sale,  exchange,  conversion  or
redemption of the  debentures  at a gain.  See "Certain  United  States  Federal
Income Tax Consequences."

Terrorist attacks,  such as the attacks that occurred in New York,  Pennsylvania
and  Washington,  D.C. on September 11, 2001,  and future war or risk of war may
adversely impact our results of operations,  our ability to raise capital or our
future growth.

    The impact that the terrorist  attacks of September 11, 2001 may have on our
industry  in  general,  and on us in  particular,  is not  known  at this  time.
Uncertainty  surrounding  retaliatory  military strikes or a sustained  military
campaign may impact our operations in unpredictable ways, including  disruptions
of fuel  supplies  and  markets,  particularly  oil,  and the  possibility  that
infrastructure  facilities,  including  electric  generation,  transmission  and
distribution facilities,  could be direct targets of, or indirect casualties of,
an act of  terror.  War or risk of war may also  have an  adverse  effect on the
economy.  A lower level of economic activity could result in a decline in energy
consumption  which could  adversely  affect our  revenues or restrict our future
growth.  Instability  in the  financial  markets as a result of terrorism or war
could also affect our ability to raise capital.


                       RATIO OF EARNINGS TO FIXED CHARGES

    The table below sets forth the ratio of earnings to fixed  charges of us and
our  consolidated  subsidiaries  on a  historical  basis for each of the periods
indicated:

                     Six Months              Year Ended December 31,
                   Ended June 30,
                       2001           2000    1999    1998    1997    1996
                  --------------    ------- ------- ------- ------- ------
                       2.2            1.5     2.0      *      1.4     1.9
                                         ----------

* For the year ended  December  31, 1998,  fixed  charges  exceeded  earnings by
approximately $177 million.

    The ratio of  earnings to fixed  charges is computed by dividing  (i) income
from continuing operations before income taxes and minority interest, plus fixed
charges and distributed income of unconsolidated affiliates,  less equity income
in  unconsolidated  affiliates,  capitalized  interest and minority  interest in
losses by (ii) fixed charges.  Fixed charges consist of interest  expense on all
indebtedness (including  amortization of deferred financing costs),  capitalized
interest   and  the  portion  of  operating   lease   rental   expense  that  is
representative of the interest factor.

    We currently  intend to retain any future  earnings to fund the  development
and growth of our  business.  Therefore,  we do not  anticipate  paying any cash
dividends  on our common  stock in the  foreseeable  future.  See  "Management's

                            DESCRIPTION OF DEBENTURES

    We issued the debentures under an Indenture dated as of May 31, 2001 between
us and Bankers Trust Company, as trustee.

    The debentures are our senior  unsecured  obligations  and are limited to an
aggregate  principal amount of $750,000,000.  The debentures will mature on June
15, 2021. The debentures rank equally with all of our existing and future senior
unsecured indebtedness.

    The debentures  were issued at a price to investors of $1,000 per debenture.
The debentures  accrue  interest at a rate of 2.5% per year from May 31, 2001 or
from the most recent  interest  payment date to which  interest has been paid or
duly  provided,  payable  semiannually  in arrears on June 15 and December 15 of
each year,  beginning  December  15, 2001.  In  addition,  we will pay an upward
interest adjustment (as defined below) if it becomes payable. The maturity value
of each debenture may exceed $1,000 in the event an upward  interest  adjustment
becomes  payable  on  the  debentures.   The  debentures  were  issued  only  in
denominations  of $1,000  principal  amount and  multiples  of $1,000  principal
amount.

    Interest,  including  additional  amounts in the event of an upward interest
adjustment,  will be paid to the person in whose name a debenture is  registered
at the  close  of  business  on  June 1 or  December  1,  as the  case  may  be,
immediately  preceding  the  relevant  interest  payment  date.  Interest on the
debentures  will be computed on the basis of a 360-day  year  composed of twelve
30-day months.

    You have the option to convert  your  debentures  into  shares of our common
stock at a conversion rate of 14.7167 shares of common stock per debenture. This
is  equivalent  to an  initial  conversion  price of $67.95  per share of common
stock.  The  conversion  rate is subject to adjustment if certain  events occur.
Upon conversion,  you will receive only shares of our common stock. You will not
receive any cash payment for interest accrued to the conversion date.

    If any interest  payment date,  maturity date,  redemption  date or purchase
date of a  debenture  falls on a day that is not a business  day,  the  required
payment of principal and interest will be made on the next  succeeding  business
day as if made on the date that the payment was due and no interest  will accrue
on that  payment  for the  period  from and after  the  interest  payment  date,
maturity date, redemption date or purchase date, as the case may be, to the date
of that payment on the next  succeeding  business day. The term  "business  day"
means, with respect to any debenture, any day other than a Saturday, a Sunday or
a day on which banking  institutions  in The City of New York are  authorized or
required by law, regulation or executive order to close.

    Each holder has agreed in the  Indenture,  for United States  federal income
tax purposes,  to treat the debentures as "contingent  payment debt instruments"
and to be bound by our  application  of the  Treasury  regulations  that  govern
contingent  payment debt instruments,  including our determination that the rate
at which  interest will be deemed to accrue for United States federal income tax
purposes  will be 8.543%,  which is the rate  comparable to the rate at which we
would have been able to borrow on a noncontingent,  nonconvertible  borrowing at
the time of  issuance.  Accordingly,  each  holder  will be  required  to accrue
interest  on a constant  yield to maturity  basis at that rate,  with the result
that a holder will  recognize  taxable  income  significantly  in excess of cash
received  while the  debentures  are  outstanding.  In  addition,  a holder will
recognize ordinary income upon a conversion of a debenture into our common stock
equal  to the  excess,  if  any,  of the  value  of the  stock  received  on the
conversion and the sum of the original purchase price of the holder's  debenture
and  accrued  but  unpaid  interest.  However,  the  proper  application  of the
regulations  that govern  contingent  payment debt  instruments to a holder of a
debenture  is  uncertain  in a number of  respects,  and if our  treatment  were
successfully  challenged by the Internal Revenue Service, it might be determined
that, among other differences, a holder should have accrued interest income at a
lower rate, should not have recognized  income or gain upon the conversion,  and
should not have  recognized  ordinary  income upon a taxable  disposition of its
debenture.

    EACH INVESTOR SHOULD CONSULT ITS TAX ADVISOR  REGARDING THE TAX TREATMENT OF
AN INVESTMENT IN THE  DEBENTURES  AND WHETHER AN INVESTMENT IN THE DEBENTURES IS
ADVISABLE  IN  LIGHT  OF THE  AGREED  UPON  TAX  TREATMENT  AND  THE  INVESTOR'S
PARTICULAR TAX SITUATION.

Interest Adjustment

    The interest rate on the  debentures is 2.5% per year through June 15, 2004.
If the  average of the closing  sales price of our common  stock is less than or
equal to 45% of the accreted  conversion  price of the debentures for any 20 out
of the last 30 trading  days ending five days prior to each June 15 and December
15, as  applicable,  commencing  June 15, 2004,  then the  interest  rate on the
debentures  will be subject to an upward  interest  adjustment to the applicable

                                       15


reset rate for the subsequent six-month period. If an upward interest adjustment
is then in effect and the average of the closing sales price of our common stock
is not  less  than or  equal  to 45% of the  accreted  conversion  price  of the
debentures  for any 20 out of the last 30 trading days of any  six-month  period
ending on the fifth day preceding  each June 15 and December 15, as  applicable,
then the interest rate on the  debentures for the  subsequent  six-month  period
will revert to 2.5% per year. If an upward interest  adjustment is in effect for
a particular  six-month period, we will pay a portion of the interest adjustment
as cash interest at a rate of 0.25% per annum  (0.125% per six-month  period) of
the principal amount,  plus any accrued and unpaid interest  (excluding interest
payable in cash),  and the  remaining  interest  will be accrued  and payable at
maturity or upon the redemption or repurchase of the debentures. Following a tax
event (as defined below), we may elect to pay interest entirely in cash.

    In the event of an upward  interest  adjustment,  the maturity  value of the
debentures will exceed their initial maturity value of $1,000.

    The "sale price" of our common stock on any date means the closing per share
sale price (or if no closing sale price is reported,  the average of the bid and
asked prices or, if more than one in either case, the average of the average bid
and the  average  asked  prices) on that date as  reported on the New York Stock
Exchange or, if our common  stock is not listed on the New York Stock  Exchange,
then as reported by the NASDAQ system.

    In the event of any upward interest adjustment,  we will disseminate a press
release through Dow Jones & Company,  Inc. or Bloomberg Business News containing
this  information  or publish the  information  on our Web site or through  such
other public medium as we may use at that time.

    The  "applicable  reset rate" for any six-month  period in which there is an
upward  interest  adjustment  will be set as of the purchase  date on which such
adjustment  is required or, if the  adjustment  is required as of a date that is
not a purchase date, the immediately  preceding  purchase date, as determined by
the reset rate agent (as defined below). The applicable reset rate will be equal
to the rate (the "reference  fixed rate") that would, in the sole and reasonable
judgment  of the  reset  rate  agent,  result  in a  trading  price of par for a
hypothetical issue of our senior,  non-convertible,  fixed-rate, callable (after
June 15, 2006) debt securities with:

    (i)a final  maturity  equal to the term from the most recent  purchase  date
until the next purchase date;

    (ii)an aggregate  principal amount equal to the then principal amount of the
        debentures plus accrued and unpaid interest (other than interest payable
        in cash); and

    (iii)provisions  that are,  insofar as would be practicable  for an issue of
         senior,  non-convertible,  fixed-rate,  callable  (after June 15, 2006)
         debt securities, substantially identical to those of the debentures.

    In no case, however, will the applicable reset rate for the period from June
15, 2004 to June 15, 2006 be greater than 10% per year without our prior written
consent.  Also, if the reset rate agent  determines in its  reasonable  judgment
that there is no suitable reference fixed rate, the applicable rate of accretion
for  that  period  will be the  applicable  rate  then in  effect  such  rate of
accretion to remain in effect until the reset rate agent  determines  that there
is a suitable  reference  fixed  rate at which  time the reset rate agent  shall
determine a new applicable reset rate for the period ending on the next purchase
date.  The  applicable  reset rate for a debenture  that is subject to an upward
interest  adjustment  shall  be  determined  as to any  period  for  which  such
adjustment is applicable until a new applicable reset rate is in effect or until
the original interest rate is again in effect.

Reset Rate Agent; Determinations Conclusive

    Salomon Smith Barney Inc. is the reset rate agent. For the  determination of
the applicable  reset rate, the reset rate agent will seek indicative  reference
rates from one other nationally recognized investment bank. The determination of
any applicable  reset rate will be made by the reset rate agent by averaging the
indicative  reference rates obtained by Salomon Smith Barney Inc. and such other
investment  bank. The  determination  of any applicable  reset rate by the reset
rate agent will be  conclusive  and binding  upon the reset rate agent,  us, the
Trustee and the holders of the debentures, in the absence of manifest error.

    The reset rate agent may be removed at any time with or without  cause if we
give at least sixty (60) days' written notice to the reset rate agent. The reset
rate agent may resign at any time upon giving at least thirty (30) days' written
notice to us. A successor reset rate agent will be appointed by us.


                                       16



Interest

    We will  pay  interest  on the  debentures  at a rate of 2.5% per  year.  In
addition,  we will pay  additional  interest in the event of an upward  interest
adjustment.  Interest will be based on a 360-day year comprised of twelve 30-day
months,  and will be  payable  semiannually  on June 15 and  December  15.  Cash
interest as a result of an upward  interest  adjustment will be paid at the rate
of 0.25% per year (0.125% per six-month period). The record date for the payment
of interest to holders will be June 1 and  December 1 of each year.  Following a
tax event, we may elect to pay interest entirely in cash. We will give notice to
the holders of the debentures,  no later than 30 days prior to each record date,
of the amount of cash interest to be paid as of the next interest  payment date.
We will pay interest on the  debentures  by wire  transfer or by check mailed to
the address of the  registered  holders of the  debentures as of the record date
relating to each interest payment date.

    You should be aware that  interest  that accrues for the period you hold the
debentures  must be  included  in your gross  income for United  States  federal
income tax purposes in accordance with the Treasury regulations that govern debt
instruments  providing for contingent  payments.  For more information,  see the
discussion below in the section captioned  "Certain United States Federal Income
Tax Consequences."

Tax Event

    We can elect to pay the entire interest adjustment on the debentures in cash
from and after  the date a tax  event  (as  defined  below)  occurs  instead  of
accreting the principal amount of the debentures. If that happens, the principal
amount  on  which  we pay  interest  will be  restated  and will be equal to the
principal  amount as of the day of restatement  plus accrued and unpaid interest
(excluding  interest  payable  in cash  prior to our  election).  This  restated
principal  amount will be the amount due at  maturity.  If we elect this option,
interest will be based on a 360-day year comprised of twelve 30-day months. Cash
interest at the higher rate will accrue from our option  exercise  date and will
be  payable  semiannually  in  arrears  on June 15 and  December  15  (each,  an
"Interest Payment Date").

    The term "tax event"  means the receipt by us of an opinion of a  nationally
recognized  independent  tax counsel  experienced  in such matters to the effect
that, as a result of:

    o   any amendment to or change (including any announced  prospective  change
        (which  does  not  include  a  proposed  change))  in the  laws  (or any
        regulations   thereunder)   of  the  United   States  or  any  political
        subdivision  or taxing  authority of the United  States or any political
        subdivision,  provided that a tax event does not occur more than 90 days
        before  the  effective  date of any  prospective  change in such laws or
        regulations; or

    o   any judicial decision or official administrative pronouncement,  ruling,
        regulatory  procedure,  notice or announcement,  including any notice or
        announcement  of intent to adopt  such  procedures  or  regulations  (an
        "administrative action"); or

    o   any   amendment  to  or  change  in  the   administrative   position  or
        interpretation  of any  administrative  action or judicial decision that
        differs from the previously  generally accepted position,  in each case,
        by any legislative body, court,  governmental agency or regulatory body,
        irrespective  of the  manner in which such  amendment  or change is made
        known,  which  amendment or change is  effective or such  administrative
        action or decision is announced, in each case, on or after May 31, 2001;

there is more  than an  insubstantial  risk  that  interest  on the  debentures,
including interest pursuant to an upward interest adjustment, either:

    o   would not be deductible on a current accrual basis; or

    o would not be deductible under any other method, in whole or in part, by us
for United States federal income tax purposes.

Optional Redemption

    No sinking fund is provided for the debentures.  Prior to June 18, 2006, the
debentures are not  redeemable.  On or after June 18, 2006, at our option we may
redeem  the  debentures  for cash at any time in whole,  or from time to time in
part,  for a cash price equal to 100% of the principal  amount of the debentures
to be redeemed, plus any accrued and unpaid interest. We will give not less than
30 days,  nor more  than 60 days  notice,  of  redemption  by mail to  debenture
holders.

    If we decide to redeem  fewer than all of the  outstanding  debentures,  the
Trustee will select the debentures to be redeemed by lot, or on a pro rata basis
or by another method the Trustee considers fair and appropriate.

                                       17


    If the Trustee  selects a portion of your  debenture for partial  redemption
and you convert a portion of the same debenture,  the converted  portion will be
deemed to be from the portion selected for redemption.

    In the event of any redemption in part, we are not required to:

    o   issue,  register  the  transfer of or exchange  any  debenture  during a
        period beginning at the opening of business 15 days before any selection
        of debentures  for redemption and ending at the close of business on the
        earliest  date on which the relevant  notice of  redemption is deemed to
        have been given to all holders of debentures to be so redeemed; and

    o   register  the  transfer of or exchange  any  debenture  so selected  for
        redemption,  in whole or in part,  except the unredeemed  portion of any
        debenture being redeemed in part.

Conversion Rights

    Subject to the conditions described below, holders may convert each of their
debentures  into  shares of our common  stock at a  conversion  ratio of 14.7167
shares of common stock per $1,000 principal amount of debentures  (equivalent to
an initial  conversion  price of $67.95 per share of common  stock  based on the
issue  price  of  the  debentures).  The  conversion  rate  and  the  equivalent
conversion  price in effect at any given time are referred to in this prospectus
as  the  applicable   conversion  rate  and  the  applicable  conversion  price,
respectively,  and will be  subject  to  adjustment  as  described  below.  If a
debenture  has been called for  redemption,  holders will be entitled to convert
the  debentures  from the date of  notice of the  redemption  until the close of
business two business  days  immediately  preceding  the date of  redemption.  A
holder may convert  fewer than all of such  holder's  debentures  so long as the
debentures converted are an integral multiple of $1,000 principal amount.

    Holders may surrender  their  debentures for  conversion  into shares of our
common  stock prior to stated  maturity if any of the  following  conditions  is
satisfied:

    o   during any  conversion  period (as defined  below) if the closing  sales
        price of our common stock for at least 20 trading days in the 30 trading
        day  period  ending on the first day of such  conversion  period is more
        than 110% of the accreted conversion price per share of the common stock
        on the first day of the conversion period;

    o   if we have called the debentures for redemption; or

    o   upon the occurrence of specified corporate transactions.

Conversion Upon Satisfaction of Market Price Condition

    A holder may surrender any of its debentures  for conversion  into shares of
our common stock during any conversion  period if the closing sales price of our
common stock on the principal national  securities  exchange on which the common
stock is listed,  for a period of at least 20  trading  days in the period of 30
consecutive  trading days ending on the first day of such  conversion  period is
more than 110% of the accreted conversion price per share of common stock on the
first day of the conversion period.  The accreted  conversion price per share of
our common  stock as of any day will equal 100% of the  principal  amount of the
debentures,  plus accrued and unpaid  interest  (excluding  interest  payable in
cash),  divided by the number of shares of common stock issuable upon conversion
of such  debenture on that day. A conversion  period will be the period from and
including the twelfth  trading day in a fiscal  quarter to but not including the
twelfth trading day in the immediately following fiscal quarter.

Conversion Upon Redemption

    A holder may  surrender  for  conversion  any of the  debentures  called for
redemption at any time prior to the close of business two business days prior to
the redemption date, even if it is not otherwise  convertible at such time. If a
holder has already delivered a purchase notice or a Fundamental  Change purchase
notice with respect to a debenture,  however,  the holder may not surrender that
debenture for conversion until the holder has withdrawn the notice in accordance
with the Indenture.

Conversion Upon Specified Corporate Transactions

    Even if the market price condition  described above has not occurred,  if we
elect to:

                                     18


    o   distribute to all holders of our common stock certain  rights  entitling
        them to purchase,  for a period expiring  within 60 days,  shares of our
        common stock at less than the sale price at the time, or

    o   distribute  to all holders of our common  stock any of our assets,  debt
        securities  or  certain  rights  to  purchase  our   securities,   which
        distribution  has a per share value exceeding 12.5% of the closing sales
        price of our common stock on the business day preceding the  declaration
        date for such distribution,

we must  notify  the  holders  of the  debentures  at least 20 days prior to the
ex-dividend date for such distribution.  Once we have given such notice, holders
may surrender  their  debentures for conversion at any time until the earlier of
the close of business on the business day prior to the  ex-dividend  date or our
announcement  that such  distribution  will not take place. No adjustment to the
ability  of a  holder  to  convert  will  be made if the  holder  may  otherwise
participate in the distribution without conversion.

    In addition,  if we are party to a  consolidation,  merger or binding  share
exchange  pursuant  to which our  common  stock  would be  converted  into cash,
securities or other property,  a holder may surrender  debentures for conversion
at any time from and after the date  which is 15 days  prior to the  anticipated
effective  date of the  transaction  until 15 days after the actual date of such
transaction.  If we are a party to a  consolidation,  merger  or  binding  share
exchange  pursuant to which our common stock is converted into cash,  securities
or other property,  then at the effective time of the transaction,  the right to
convert a debenture into common stock will be changed into a right to convert it
into the kind and amount of cash,  securities or other property which the holder
would have received if the holder had converted its debentures immediately prior
to the transaction. If the transaction also constitutes a Fundamental Change, as
defined  below,  a holder  can  require us to  purchase  all or a portion of its
debentures as described below under "-- Fundamental Change."

    The conversion agent will on our behalf determine at the end of each quarter
if the debentures are convertible and notify us and the Trustee.

    You will not  receive  any cash  payment  representing  accrued  and  unpaid
interest  upon  conversion  of a debenture.  Instead,  upon  conversion  we will
deliver to you a fixed number of shares of our common stock and any cash payment
to account for fractional shares. The cash payment for fractional shares will be
based  on the  closing  sales  price of our  common  stock  on the  trading  day
immediately  prior to the  conversion  date.  Delivery of shares of common stock
will be deemed to satisfy  our  obligation  to pay the  principal  amount of the
debentures,  including  accrued  interest.  Accrued and unpaid  interest will be
deemed paid in full rather than canceled, extinguished or forfeited. We will not
adjust the conversion rate to account for the accrued interest.

    If you  wish  to  exercise  your  conversion  right,  you  must  deliver  an
irrevocable  conversion notice,  together, if the debentures are in certificated
form, with the certificated  security, to the conversion agent who will, on your
behalf,  convert the debentures into shares of our common stock.  You may obtain
copies of the required form of the conversion notice from the conversion agent.

    Based on our treatment of the  debentures  for United States  federal income
tax  purposes,  as  discussed  above,  a holder  would be required to  recognize
ordinary  income upon a conversion of a debenture into our common stock equal to
the excess,  if any,  between the value of the stock  received on the conversion
and the sum of the original purchase price of the holder's debenture and accrued
but unpaid interest. For a more detailed discussion,  see "Certain United States
Federal Income Tax Consequences."

    The conversion rate will be subject to adjustment upon the following events:

    o   the payment of dividends and other distributions payable exclusively in
        shares of our common stock on our common stock;

    o   the  issuance to all  holders of our common  stock of rights or warrants
        that allow the  holders to purchase  shares of our common  stock at less
        than the then current market price;  provided that no adjustment will be
        made if holders of the debentures may  participate in the transaction on
        a basis and with notice  that our board of  directors  determines  to be
        fair and appropriate or in some other cases;

    o   subdivisions or combinations of our common stock;

    o   payment of dividends or distributions to all holders of our common stock
        consisting  of  evidences  of our  indebtedness,  securities  or capital
        stock,  cash or assets,  excluding any rights or warrants referred to in
        the second  bullet  point above and  dividends  and  distributions  paid
        solely in cash;

    o   payment of dividends or distributions on our common stock paid
        exclusively in cash, excluding:

                                     19


        o  cash  dividends  that do not  exceed  the  per  share  amount  of the
           immediately  preceding regular cash dividend,  as adjusted to reflect
           any of the events described in the preceding bullet points,

        o  cash  dividends,  if the annualized per share amount thereof does not
           exceed  12.5% of the current  market price of our common stock on the
           trading  day  immediately  prior  to the date of  declaration  of the
           dividend, and

        o  a redemption of any rights issued under a rights agreement; and

    o   payment  to  holders  of our  common  stock in  respect  of a tender  or
        exchange  offer,  other  than  an  odd-lot  offer,  made  by us  or  any
        subsidiary of ours for our common stock in excess of 110% of the current
        market price of our common  stock as of the trading day next  succeeding
        the last date tenders or exchanges may be made in the tender or exchange
        offer.

    In the  event we elect to make a  distribution  described  in the  second or
fifth bullet above which, in the case of the fifth bullet, has a per share value
equal to more than  12.5% of the  closing  sales  price of our  shares of common
stock on the day preceding the declaration date for such  distribution,  we will
be required to give  notice to the  holders of the  debentures  at least 20 days
prior to the ex-dividend date for such distribution and, upon the giving of such
notice,  the debentures may be surrendered  for conversion at any time until the
close of business on the business day prior to the ex-dividend  date or until we
announce  that such  distribution  will not take  place.  No  adjustment  to the
conversion  rate or the  ability of a holder of a debenture  to convert  will be
made if the  holder  will  otherwise  participate  in the  distribution  without
conversion or in certain other cases.

    If our stockholder rights plan, dated August 22, 2000, is triggered, holders
of the  debentures  will be entitled to receive  these rights  provided that the
debentures are converted  into shares of common stock prior to the  distribution
of the separate  certificate  representing  those rights.  There will not be any
adjustment to the conversion rate as a result of:

    o   the issuance of the rights;

    o   the distribution of separate certificates representing the rights;

    o   the exercise or redemption of the rights in accordance with any rights
        agreement; or

    o   the termination or invalidation of the rights.

    The applicable conversion price will not be adjusted:

    o   upon the  issuance  of any shares of our common  stock  pursuant  to any
        present or future plan  providing for the  reinvestment  of dividends or
        interest  payable on our  securities  and the  investment  of additional
        optional amounts in shares of our common stock under any plan;

    o   upon the issuance of any shares of our common stock or options or rights
        to purchase  those  shares  pursuant to any present or future  employee,
        director or consultant benefit plan or program of Mirant; or

    o   upon the  issuance  of any shares of our common  stock  pursuant  to any
        option,  warrant,  right,  or  exercisable,  exchangeable or convertible
        security outstanding as of the date the debentures were first issued.

    We may  increase  the  conversion  rate as  permitted by law for at least 20
days, so long as the increase is  irrevocable  during the period.  If any action
would  require  adjustment  of the  conversion  rate  under more than one of the
provisions described above, only one adjustment will be made and that adjustment
will be the amount of  adjustment  that has the  highest  absolute  value to the
holders of the debentures. No adjustment in the applicable conversion price will
be required  unless the  adjustment  would require an increase or decrease of at
least 1% of the  applicable  conversion  price.  If the  adjustment  is not made
because the adjustment does not change the applicable  conversion  price by more
than 1%, then the adjustment  that is not made will be carried forward and taken
into account in any future adjustment.  Except as specifically  described above,
the applicable  conversion price is not subject to adjustment in the case of the
issuance  of any  of  our  common  stock,  or  securities  convertible  into  or
exchangeable for our common stock.


                                       20



Purchase of Debentures by Mirant at the Option of the Holder

    Holders have the right to require us to purchase the  debentures on June 15,
2004,  June 15, 2006,  June 15, 2011,  and June 15, 2016. We will be required to
purchase  any  outstanding  debentures  for  which a holder  delivers  a written
purchase  notice to the paying agent.  This notice must be delivered  during the
period beginning at any time from the opening of business on the date that is 20
business days prior to the relevant purchase date until the close of business on
the last day prior to the purchase  date.  If the  purchase  notice is given and
withdrawn  during the  period,  we are not  obligated  to  purchase  the related
debentures.   Our  purchase  obligation  will  be  subject  to  some  additional
conditions  as  described  in the  Indenture.  Also,  our ability to satisfy our
purchase  obligations may be affected by the factors described in "Risk Factors"
under the caption "We may not have the ability to raise the funds  necessary  to
finance  the  Fundamental  Change  purchase  or  purchase  at the  option of the
holder."

    The purchase price payable will be equal to 100% of the principal  amount of
the  debentures  to be  purchased  plus any accrued and unpaid  interest to such
purchase date.

    We may  choose to pay the  purchase  price in cash or  shares of our  common
stock or a combination of cash and shares of our common stock,  provided that we
will pay any accrued  cash  interest  in cash.  For a  discussion  of the United
States federal income tax treatment of a holder receiving cash, shares of common
stock or any combination  thereof, see "Certain United States Federal Income Tax
Consequences."

    If we choose to pay the purchase  price in whole or in part in shares of our
common stock or a combination  of cash and shares of our common  stock,  we must
give notice on a date not less than 20 business days prior to each purchase date
to all holders at their addresses shown in the register of the registrar, and to
beneficial  owners as required by applicable law (if no notice is given, we will
pay the purchase price with cash), stating, among other things:

    o   whether we will pay the purchase  price of the  debentures  in cash,  in
        shares of our common stock, or any combination  thereof,  specifying the
        percentages of each;

    o   if we elect to pay with shares of our common stock, the method of
        calculating the price of our common stock; and

    o   the procedures that holders must follow to require us to purchase  their
        debentures.

    If we pay with  shares of our common  stock,  they will be valued at 100% of
the average  closing  sales price for the five  trading days ending on the third
day prior to purchase.

    Simultaneously  with such notice of purchase,  we will  disseminate  a press
release through Dow Jones & Company,  Inc. or Bloomberg Business News containing
this  information  or publish the  information  on our Web site or through  such
other public medium as we may use at that time.

    A holder's  notice  electing to require us to purchase your  debentures must
state:

    o   if certificated  debentures have been issued, the debentures certificate
        numbers,   or  if  not  certificated,   your  notice  must  comply  with
        appropriate DTC procedures;

    o   the portion of the principal amount of debentures to be purchased, in
        multiples of $1,000;

    o   that the debentures are to be purchased by us pursuant to the applicable
        provisions of the debentures; and

    o   in the event we elect,  pursuant to the notice  that we are  required to
        give, to pay the purchase price in shares of our common stock,  in whole
        or in  part,  but the  purchase  price is  ultimately  to be paid to the
        holder  entirely in cash because any of the conditions to payment of the
        purchase  price or portion of the purchase price in shares of our common
        stock is not  satisfied  prior to the close of  business on the last day
        prior to the  purchase  date,  as  described  below,  whether the holder
        elects:

        (1)to withdraw the purchase notice as to some or all of the debentures
           to which it relates, or

        (2)to  receive  cash in respect  of the  entire  purchase  price for all
           debentures or portions of debentures subject to the purchase notice.

                                     21


    If the holder  fails to indicate  the  holder's  choice with  respect to the
election described in the final bullet point above, the holder will be deemed to
have  elected to receive  cash in respect of the entire  purchase  price for all
debentures  subject  to  the  purchase  notice  in  these  circumstances.  For a
discussion  of the  United  States  federal  income  tax  treatment  of a holder
receiving cash instead of shares of our common stock, see "Certain United States
Federal Income Tax Consequences."

    You may  withdraw  any  purchase  notice by a written  notice of  withdrawal
delivered  to the paying  agent  prior to the close of  business on the last day
prior to the purchase date. The notice of withdrawal must state:

    o   the principal amount of the withdrawn debentures;

    o   if certificated  debentures have been issued, the certificate numbers of
        the  withdrawn  debentures,  or if not  certificated,  your  notice must
        comply with appropriate DTC procedures; and

    o   the principal amount, if any, which remains subject to the purchase
        notice.

    If we elect to pay the purchase price, in whole or in part, in shares of our
common  stock,  the number of shares to be  delivered by us will be equal to the
portion of the purchase  price to be paid in shares of our common stock  divided
by the market price of one share of our common stock as  determined by us in our
company  notice.  We will pay cash based on the market price for all  fractional
shares.

    The "market price" means the average sales price of our common stock for the
five trading day period ending on the third business day prior to the applicable
purchase date (if the third business day prior to the  applicable  purchase date
is a trading  day,  or if not,  then on the last  trading day prior to the third
business  day),  appropriately  adjusted to take into  account  the  occurrence,
during the period  commencing  on the first of the trading  days during the five
trading day period and ending on the  purchase  date,  of some events that would
result in an adjustment of the conversion rate with respect to our common stock.

    The "sale price" of our common stock on any date means the closing per share
sale price (or if no closing sale price is reported,  the average of the bid and
asked prices or, if more than one in either case, the average of the average bid
and the average asked prices) on that date as reported in composite transactions
for the principal U.S.  securities  exchange on which our common stock is traded
or, if our common stock is not listed on a U.S. national or regional  securities
exchange, as reported by the NASDAQ system.

    Because  the market  price of our common  stock is  determined  prior to the
applicable  purchase date,  holders of the debentures  bear the market risk with
respect to the value of our common stock to be received from the date the market
price is determined to the purchase  date. We may pay the purchase  price or any
portion  of the  purchase  price  in  shares  of our  common  stock  only if the
information  necessary  to  calculate  the market  price is published in a daily
newspaper of national circulation.

    Upon  determination of the actual number of shares of our common stock to be
paid upon  redemption  of the  debentures,  we will  disseminate a press release
through Dow Jones & Company,  Inc. or Bloomberg  Business News  containing  this
information  or publish the  information  on our Web site or through  such other
public medium as we may use at that time.

    A holder must either effect  book-entry  transfer or deliver the debentures,
together with  necessary  endorsements,  to the office of the paying agent after
delivery of the purchase notice to receive  payment of the purchase  price.  You
will receive payment on the purchase date or the time of book-entry  transfer or
the delivery of the  debentures.  If the paying agent holds money or  securities
sufficient  to pay the  purchase  price of the  debentures  on the  business day
following the purchase date, then:

    o   the debentures will cease to be outstanding;

    o   interest, including any interest payable pursuant to an interest
        adjustment will cease to accrue; and

    o   all other rights of the holder will terminate.

    This will be the case whether or not  book-entry  transfer of the debentures
is made or whether or not the debenture is delivered to the paying agent.

    We will comply with the  provisions of Rule 13e-4 and any other tender offer
rules under the Exchange Act which may be  applicable  at the time. We will file
Schedule TO or any other schedule required in connection with any offer by us to
purchase the debentures at your option.

                                       22


Ranking

    The debentures are our senior  unsecured  obligations  and rank equally with
all of our existing and future senior  unsecured  indebtedness and senior to our
$345  million  junior  subordinated  convertible  debentures  due 2030 issued in
connection with our outstanding trust preferred  securities.  However,  we are a
holding company and the debentures are effectively  subordinated to all existing
and future obligations of our subsidiaries.

    As  of  June  30,  2001,  we  had  approximately  $7,992  million  of  total
indebtedness   outstanding.   As  of  June  30,  2001,  our   subsidiaries   had
approximately  $6,054  million  of  outstanding   indebtedness,   to  which  the
debentures would have been structurally subordinated.

Fundamental Change

    If a Fundamental Change as defined below occurs, a holder of debentures will
have the right,  at its option,  to require us to purchase all of its debentures
not previously  called for  redemption,  or any portion of the principal  amount
thereof, that is equal to $1,000 or an integral multiple of $1,000. The price we
are required to pay is equal to 100% of the principal  amount of the  debentures
to be purchased plus accrued and unpaid interest to the purchase date.

    Within  30  days  after  the  occurrence  of a  Fundamental  Change,  we are
obligated  to  give to the  holders  of the  debentures  written  notice  of the
Fundamental  Change  and  of the  purchase  right  arising  as a  result  of the
Fundamental  Change.  We must also deliver a copy of this notice to the Trustee.
To exercise the purchase  right, a holder of the  debentures  must deliver on or
before the 30th day after the date of our notice  irrevocable  written notice to
the Trustee of the holder's  exercise of its purchase  right,  together with the
debentures with respect to which the right is being  exercised.  We are required
to  purchase  the  debentures  on the date that is 45 days after the date of our
notice.

    A Fundamental Change will be deemed to have occurred at the time that any of
the following occurs:

    (1) any  person  acquires  beneficial  ownership,  directly  or  indirectly,
        through a purchase, merger or other acquisition transaction or series of
        transactions,  of shares of our capital  stock  entitling  the person to
        exercise  50% or more of the  total  voting  power of all  shares of our
        capital  stock  that is  entitled  to vote  generally  in  elections  of
        directors ("voting stock"),  other than an acquisition by us, any of our
        subsidiaries or any of our employee benefit plans; or

    (2) we merge or  consolidate  with or into any other  person,  any merger of
        another  person  into us, or we convey,  sell,  transfer or lease all or
        substantially  all of our  assets  to  another  person,  other  than any
        transaction:

        o  that does not result in any reclassification, conversion, exchange or
           cancellation  of outstanding  shares of our capital stock (such as an
           acquisition by a subsidiary), or

        o  where  the  holders  of our  common  stock  immediately  prior to the
           transaction  have 50% or more of our total voting power of our voting
           capital stock or its successor immediately after the transaction, or

        o  which is effected solely to change our  jurisdiction of incorporation
           and results in a  reclassification,  conversion or exchange of shares
           of our common  stock  solely into  shares of our common  stock of the
           surviving entity.

    However, a Fundamental Change will not be deemed to have occurred if either:

    (A) the  closing  price per share of our common  stock for any five  trading
        days within the period of 10 consecutive trading days ending immediately
        after the later of a Fundamental Change or the public  announcement of a
        Fundamental  Change, in the case of a Fundamental  Change relating to an
        acquisition  of capital stock,  or the period of 10 consecutive  trading
        days ending immediately before the Fundamental  Change, in the case of a
        Fundamental  Change relating to a merger,  consolidation  or asset sale,
        equals or exceeds  105% of the  conversion  price of the  debentures  in
        effect on each of those trading days, or

    (B) all of the consideration  (excluding cash payments for fractional shares
        and cash payments made pursuant to  dissenters'  appraisal  rights) in a
        merger or  consolidation  otherwise  constituting  a Fundamental  Change
        under  clause (1) and/or  clause (2) above  consists of shares of common
        stock traded on a national  securities  exchange or quoted on the NASDAQ
        National  Market (or will be so traded or quoted  immediately  following
        the  merger  or  consolidation)  and  as  a  result  of  the  merger  or
        consolidation the debentures become convertible into such common stock.

                                       23



    For purposes of these provisions:

    o   the conversion price is equal to $1,000 plus accrued and unpaid interest
        (excluding any accrued and unpaid cash interest) divided by the
        conversion rate;

    o   whether a person is a "beneficial owner"will be determined in accordance
        with Rule 13d-3 under the Exchange Act; and

    o   "person"  includes  any syndicate  or group that would be deemed to be a
        "person" under Section 13(d)(3) of the Exchange Act.

    Rule 13e-4 under the Exchange Act requires the  dissemination  of prescribed
information  to security  holders in the event of an issuer tender offer and may
apply in the event that the purchase option becomes  available to the holders of
debentures. We will comply with this rule to the extent it applies at that time.

    The  definition  of  Fundamental  Change  includes a phrase  relating to the
conveyance,  transfer,  sale, lease or disposition of "all or substantially all"
of our  assets.  There  is no  precise,  established  definition  of the  phrase
"substantially all" under applicable law.  Accordingly,  the ability of a holder
of the  debentures  to require us to purchase its  debentures as a result of the
conveyance,  transfer,  sale, lease or other disposition of less than all of our
assets may be uncertain.

    The foregoing  provisions  would not necessarily  provide the holders of the
debentures  with  protection  if we are involved in a highly  leveraged or other
transaction that may adversely affect the holders.

    If a Fundamental  Change were to occur,  we may not have enough funds to pay
the Fundamental  Change purchase price. See "Risk Factors" under the caption "We
may not have the ability to raise the funds necessary to finance the Fundamental
Change purchase or purchase at the option of the holder." In addition,  we have,
and may in the future incur,  other  indebtedness with similar change in control
provisions permitting our holders to accelerate or to require us to purchase our
indebtedness  upon the occurrence of similar events or on some specified  dates.
If we fail to purchase the  debentures  when  required  following a  Fundamental
Change, we will be in default under the Indenture.

Merger and Sales of Assets by Mirant

    We may not (1)  consolidate  with or merge with or into any other  person or
convey,  transfer,  sell or lease our properties and assets  substantially as an
entirety to any person,  or (2) permit any person to  consolidate  with or merge
into us unless:

    o    we are the continuing corporation, or

    o   the person  formed by the  consolidation  or into which we are merged or
        the  person  to  which  our  properties  and  assets  are  so  conveyed,
        transferred,  sold  or  leased,  is  a  corporation,  limited  liability
        company,  partnership or trust  organized and existing under the laws of
        the United States, any State within the United States or the District of
        Columbia and, if we are not the surviving  person,  the surviving person
        assumes the payment of the  principal of and interest on the  debentures
        and the performance of our other covenants under the Indenture, and

    o   in all cases,  immediately  after giving effect to the  transaction,  no
        event of default,  and no event that,  after  notice or lapse of time or
        both,  would  become  an event of  default,  will have  occurred  and be
        continuing.

Events of Default

    The following are events of default with respect to the debentures:

    o   default for 30 days in payment of any cash  interest  due and payable on
        the debentures,  including  additional  interest  payable upon an upward
        interest adjustment;

    o   default in payment of the principal amount of the debentures and accrued
        and unpaid interest at maturity, upon redemption, purchase at the option
        of the holder or  following a  Fundamental  Change when the same becomes
        due and payable;

    o   default in our  obligation to deliver shares of our common stock upon an
        appropriate   election  by  holders  of   debentures  to  convert  those
        debentures and continuance of such default for 10 days;

                                       24


    o   failure to comply in any  material  respect  with any other  covenant or
        agreement in respect of the debentures contained in the Indenture or the
        debentures  for 90 days after written  notice to us by the Trustee or to
        us and the Trustee by the holders of at least 25% in aggregate principal
        amount of the debentures then outstanding; and

    o   certain events of bankruptcy, insolvency and reorganization of Mirant.

    The Indenture  requires that we file annually with the Trustee a certificate
describing  any material  default by us in the  performance of any conditions or
covenants that has occurred under the Indenture and its status. We must give the
Trustee  written  notice within 30 days of any default under the Indenture  that
could  mature into an event of default  described  in the fourth or fifth bullet
point above.

    The Indenture provides, that if an event of default occurs and is continuing
with  respect to the  debentures,  either the Trustee or the holders of at least
25% in aggregate principal amount of the outstanding  debentures may declare the
principal amount plus accrued and unpaid interest,  if any, on the debentures to
be due and  payable  immediately.  If an event of default  relating to events of
bankruptcy,  insolvency or reorganization occurs,  principal amount plus accrued
and unpaid interest,  if any, on the debentures will become  immediately due and
payable without any action on the part of the Trustee or any holder. At any time
after a declaration of acceleration, but before a judgment or decree for payment
of money  has been  obtained,  if all  events of  default  with  respect  to the
debentures  have been cured (other than the nonpayment of principal plus accrued
and unpaid  interest on the debentures  which has become due solely by reason of
the declaration of  acceleration)  then the declaration of acceleration  will be
automatically annulled and rescinded.

    A holder of debentures may pursue any remedy under the Indenture only if:

    o   the holder gives the Trustee written notice of a continuing event of
        default for the debentures;

    o   the holders of at least 25% in principal amount of the outstanding
        debentures make a written request to the Trustee to pursue the remedy;

    o   the holder offers to the Trustee indemnity reasonably satisfactory to
        the Trustee;

    o   the Trustee fails to comply with the request for a period of 60 days
        after receipt of notice and offer of indemnity; and

    o   during that 60-day period, the holders of a majority in principal amount
        of the debentures do not give the Trustee a direction  inconsistent with
        the request.

    This provision does not, however, affect the right of a holder of debentures
to sue for  enforcement  of payment of the  principal of or interest,  including
liquidated  damages,  on the holder's  debenture on or after the  respective due
dates  expressed in its debenture or the holder's right to convert its debenture
in accordance with the Indenture.

    The  Trustee is  entitled  under the  Indenture,  subject to the duty of the
Trustee  during a  default  to act with the  required  standard  of care,  to be
indemnified before proceeding to exercise any right or power under the Indenture
at the direction of the  registered  holders of the debentures or which requires
the  Trustee to expend or risk its own funds or  otherwise  incur any  financial
liability. The Indenture also provides that the registered holders of a majority
in principal  amount of the  outstanding  debentures (or of all debt  securities
affected,  voting  as one  class)  may  direct  the  time,  method  and place of
conducting any proceeding for any remedy  available to the Trustee or exercising
any trust or power  conferred on the Trustee  with respect to these  debentures.
The Trustee,  however,  may refuse to follow any such  direction  that conflicts
with  law or the  Indenture,  is  unduly  prejudicial  to the  rights  of  other
registered  holders of the debentures,  or would involve the Trustee in personal
liability.

    The Indenture  provides that while the Trustee generally must mail notice of
a default or event of default to the registered holders of the debentures within
90 days of occurrence,  the Trustee may withhold  notice of any default or event
of default  (except in payment on the debt  securities)  if the  Trustee in good
faith  determines  that the withholding of such notice is in the interest of the
registered holders of that series of debt securities.

Modification and Waiver

    We may amend or  supplement  the  Indenture  if the holders of a majority in
principal  amount of the  debentures  consent to it.  Without the consent of the
holder of each debenture affected, however, no modification may:

                                       25


    o   reduce the amount of debentures whose holders must consent to an
        amendment, supplement or waiver;

    o   reduce the rate of accrual of interest or change the time for payment of
        interest on the debentures;

    o   reduce  the  value of our  common  stock to which  reference  is made in
        determining   whether  an  interest  adjustment  will  be  made  on  the
        debentures, or change the method by which this value is calculated;

    o   reduce the principal amount of the debentures or change its stated
        maturity;

    o   reduce the redemption or purchase price of the debentures or change the
        time at which the debentures may or must be redeemed or purchased;

    o   make payments on the debentures payable in currency or securities other
        than as originally stated in the debentures;

    o   impair the holder's right to institute suit for the enforcement of any
        payment on the debentures;

    o   make any change in the  percentage  of  principal  amount of  debentures
        necessary to waive  compliance  with some provisions of the Indenture or
        to make any change in this provision for modification;

    o   waive a continuing default or event of default regarding any payment on
        the debentures; or

    o   adversely affect the conversion or repurchase provisions of the
        debentures.

    We may  amend or  supplement  the  Indenture  or waive any  provision  of it
without  the  consent  of any  holders  of  debentures  in  some  circumstances,
including:

    o   to cure any ambiguity, omission, defect or inconsistency;

    o   to provide for the assumption of our obligations  under the Indenture by
        a successor upon any merger,  consolidation or asset transfer  permitted
        under the Indenture;

    o   to provide for uncertificated debentures in addition to or in place of
        certificated debentures or to provide for bearer debentures;

    o   to provide any security for or guarantees of the debentures;

    o   to comply with any requirement to effect or maintain the qualification
        of the Indenture under the Trust Indenture Act of 1939;

    o   to add covenants that would benefit the holders of debentures or to
        surrender any rights we have under the Indenture;

    o   to add events of default with respect to the debentures; or

    o   to make any change  that  does  not  adversely  affect  any  outstanding
        debentures in any material respect.

    The holders of a majority in principal amount of the outstanding  debentures
may waive any  existing or past default or event of default.  Those  holders may
not,  however,  waive any  default  or event of  default  in any  payment on any
debenture or compliance  with a provision that cannot be amended or supplemented
without the consent of each holder affected.

Calculations in Respect of Debentures

    We are  responsible  for  making  all  calculations  called  for  under  the
debentures,  except for such  calculations  made by the reset rate agent.  These
calculations  include,  but are not  limited  to,  determinations  of the market
prices of our common stock,  accrued  interest payable on the debentures and the
accreted conversion price of the debentures. We will make all these calculations
in good faith and,  absent manifest error,  our  calculations  will be final and
binding on holders of debentures. We will provide a schedule of our calculations
to the  Trustee,  and the Trustee is  entitled to rely upon the  accuracy of our
calculations  without  independent  verification.  The Trustee  will forward our
calculations to any holder of debentures upon the request of that holder.

Governing Law

    The  Indenture  and  the  debentures  are  governed  by,  and  construed  in
accordance with, the laws of the State of New York.

Trustee

    Bankers Trust Company is the Trustee, registrar and paying agent.

    If an event  of  default  occurs  and is  continuing,  the  Trustee  will be
required to use the degree of care and skill of a prudent  person in the conduct
of that person's own affairs.  The Trustee will become obligated to exercise any
of its powers  under the  Indenture  at the request of any of the holders of any
debentures  only  after  those  holders  have  offered  the  Trustee   indemnity
reasonably satisfactory to it.

    If  the  Trustee  becomes  one of our  creditors,  it  will  be  subject  to
limitations  in the  Indenture  on its rights to obtain  payment of claims or to
realize on some property  received for any such claim, as security or otherwise.
The Trustee is permitted to engage in other  transactions  with us. If, however,
it acquires any conflicting interest, it must eliminate that conflict or resign.
Bankers Trust Company is currently  serving as the Trustee under other  numerous
indentures governing our debt issuances, including debt which is subordinated to
the debentures.

Form, Exchange, Registration and Transfer

    We issued the debentures in registered form,  without interest  coupons.  We
will not charge a service charge for any registration of transfer or exchange of
the  debentures.  We may,  however,  require  the  payment  of any tax or  other
governmental charge payable for that registration.

    The debentures are  exchangeable  for other  debentures,  for the same total
principal   amount  and  for  the  same  terms  but  in   different   authorized
denominations in accordance with the Indenture.  Holders may present  debentures
for  registration  of transfer at the office of the  security  registrar  or any
transfer  agent we  designate.  The security  registrar  or transfer  agent will
effect the transfer or exchange when it is satisfied with the documents of title
and identity of the person making the request.

    We have appointed the Trustee as security  registrar for the debentures.  We
may at any time  rescind  that  designation  or approve a change in the location
through  which any  registrar  acts.  We are  required  to maintain an office or
agency for transfers and exchanges in each place of payment.  We may at any time
designate additional registrars for the debentures.

    In the case of any  redemption,  the  security  registrar is not required to
register the transfer or exchange of any debentures either:

    o   during a period  beginning  15 days prior to the mailing of the relevant
        notice of  redemption  and ending on the close of business on the day of
        mailing of the notice, or

    o   if the  debentures  have been called for redemption in whole or in part,
        except the unredeemed portion of any debentures being redeemed in part.

    We do not intend to list the debentures on any securities exchange or in any
automated  quotation  system.  The  debentures  issued  in the  initial  private
placement are eligible for trading in the PORTAL Market;  however,  no assurance
can be given as to the liquidity of or trading  market for the  debentures.  The
debentures sold using this prospectus, however, will not be eligible for trading
in the  PORTAL  Market.  Our  shares of common  stock are traded on the New York
Stock Exchange under the symbol "MIR."

Payment and Paying Agents

    Payments on the debentures will be made in U.S. dollars at the office of the
Trustee.  At our option,  however,  we may make  payments by check mailed to the
holder's  registered  address or,  with  respect to global  debentures,  by wire
transfer.  We will  make  interest  payments  to the  person  in whose  name the
debentures  are  registered  at the close of business on the record date for the
interest payment.

    The Trustee is designated as our paying agent for payments on debentures. We
may at any time designate additional paying agents or rescind the designation of
any  paying  agent or approve a change in the  office  through  which any paying
agent acts.

                                       27


    Subject to the requirements of any applicable  abandoned  property laws, the
Trustee and paying agent will pay to us upon  written  request any money held by
them for payments on the  debentures  that remain  unclaimed for two years after
the date upon which that payment has become due.  After  payment to us,  holders
entitled to the money must look to us for payment.  In that case,  all liability
of the Trustee or paying agent with respect to that money will cease.

Notices

    Except as otherwise  described herein,  notice to registered  holders of the
debentures will be given by mail to the addresses as they appear in the security
register. Notices will be deemed to have been given on the date of such mailing.

Replacement of Debentures

    We will replace any debentures that become mutilated,  destroyed,  stolen or
lost upon delivery to the Trustee of the mutilated debentures or evidence of the
loss, theft or destruction  satisfactory to us and the Trustee. In the case of a
lost, stolen or destroyed debentures,  indemnity satisfactory to the Trustee and
us may be required before a replacement debenture will be issued.

Payment of Stamp and Other Taxes

    We will pay all stamp and other duties,  if any, which may be imposed by the
United States or any political  subdivision  thereof or taxing authority thereof
or therein with respect to the issuance of the  debentures.  We are not required
to make any payment with respect to any other tax,  assessment  or  governmental
charge imposed by any government or any political  subdivision thereof or taxing
authority thereof or therein.

Book-Entry System

    The debentures are represented by a global security. This global security is
on deposit with, or on behalf of, DTC and is registered in the name of a nominee
of DTC. Except under  circumstances  described below, the debentures will not be
issued in definitive form.

    When  the  global  security  was  issued,  DTC  credited  on its  book-entry
registration  and  transfer  system the  accounts of persons  designated  by the
initial  purchaser  with the  respective  principal  amounts  of the  debentures
represented  by the global  security.  Ownership  of  beneficial  interests in a
global security is limited to persons that have accounts with DTC or its nominee
("participants")  or  persons  that may  hold  interests  through  participants.
Ownership  of  beneficial  interests  in a global  security is shown on, and the
transfer of that ownership will be effected only through,  records maintained by
DTC  or  its  nominee   (with   respect  to  interests  of  persons  other  than
participants).  The  laws  of  some  states  require  that  some  purchasers  of
securities  take physical  delivery of the securities in definitive  form.  Such
limits and such laws may impair the ability to transfer beneficial  interests in
a global security.

    So long as DTC or its nominee is the registered  owner of a global security,
DTC or its  nominee,  as the case may be, will be  considered  the sole owner or
holder of the debentures  represented  by that global  security for all purposes
under the Indenture. Except as provided below, owners of beneficial interests in
a global security are not entitled to have debentures represented by that global
security  registered in their names,  will not receive or be entitled to receive
physical  delivery of debentures  in definitive  form and will not be considered
the  owners or holders  thereof  under the  Indenture.  Principal  and  interest
payments,  on  debentures  registered  in the name of DTC or its nominee will be
made to DTC or its nominee,  as the case may be, as the registered  owner of the
relevant  global  security.  Neither we, the  Trustee,  any paying  agent or the
registrar for the debentures will have any  responsibility  or liability for any
aspect of the records  relating to nor  payments  made on account of  beneficial
interests in a global security or for maintaining,  supervising or reviewing any
records relating to such beneficial interests.

    We expect that DTC or its nominee,  upon receipt of any payment of principal
or interest,  will credit  immediately  participants'  accounts with payments in
amounts  proportionate to their respective beneficial interests in the principal
amount of the  relevant  global  security  as shown on the records of DTC or its
nominee.  We also expect that payments by  participants  to owners of beneficial
interests in a global security held through these  participants will be governed
by standing instructions and customary practices, as is the case with securities
held for the  accounts  of  customers  in bearer form or  registered  in "street
name," and will be the responsibility of the participants.

    If DTC is at any time  unwilling or unable to continue as a depositary and a
successor  depositary  is not  appointed  by us within 90 days or if an event of
default occurs and is continuing with respect to the  debentures,  we will issue
debentures in definitive form in exchange for the entire global security for the
debentures. In addition, we may at any time and in our sole discretion determine

                                       28


not to have debentures represented by a global security and, in such event, will
issue  debentures in definitive  form in exchange for the entire global security
relating  to the  debentures.  In any such  instance,  an owner of a  beneficial
interest  in a  global  security  will  be  entitled  to  physical  delivery  in
definitive  form of  debentures  represented  by the  global  security  equal in
principal  amount  to  the  beneficial  interest  and  to  have  the  debentures
registered in its name.  Debentures so issued in definitive  form will be issued
as  registered  debentures  in  denominations  of $1,000 and integral  multiples
thereof, unless otherwise specified by us.

                                       29



              CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

    The following is a summary of the material  United States federal income tax
consequences  of the purchase,  ownership and  disposition of the debentures and
the shares of common  stock into which the  debentures  may be  converted.  This
summary  deals only with the  debentures  and the shares of common stock held as
capital assets for United States  federal  income tax purposes.  As used in this
prospectus,  "U.S.  Holders" are any beneficial  owners of the debentures or the
shares of common stock that are, for United States  federal income tax purposes:
(1) citizens or  residents of the United  States,  (2)  corporations  created or
organized in or under the laws of the United  States,  any state  thereof or the
District  of  Columbia,  (3)  estates,  the income of which is subject to United
States federal income taxation  regardless of its source,  and (4) trusts,  if a
court within the United States is able to exercise primary  supervision over the
administration  of the  trust and one or more  United  States  persons  have the
authority to control all  substantial  decisions  of the trust.  As used in this
prospectus,  "Non-U.S.  Holders" are holders of the  debentures or the shares of
common  stock that are,  for United  States  federal  income tax  purposes,  (1)
nonresident alien individuals,  (2) foreign corporations and (3) foreign estates
or trusts that are not subject to United States federal income taxation on their
worldwide  income.  If a  partnership  (including  for this  purpose  any entity
treated as a  partnership  for United States  federal  income tax purposes) is a
beneficial  owner of the debentures or the shares of common stock, the treatment
of a partner in the  partnership  will  generally  depend upon the status of the
partner and upon the activities of the  partnership.  A holder of the debentures
or the  shares  of common  stock  that is a  partnership  and  partners  in such
partnership  should  consult their tax advisors  about the United States federal
income tax consequences of holding and disposing of the debentures or the shares
of common stock, as the case may be. Unless otherwise stated,  this summary does
not deal with  special  classes of holders such as banks,  thrifts,  real estate
investment trusts, regulated investment companies,  insurance companies, dealers
in  securities  or  currencies,  tax-exempt  investors,  holders  that  hold the
debentures  as  part  of  a  hedge,  straddle,  "synthetic  security"  or  other
integrated transaction for United States federal income tax purposes and holders
whose functional currency is not the U.S. dollar. Further, this summary does not
include any  description of any  alternative  minimum tax  consequences,  United
States  federal  estate or gift tax laws or the tax laws of any state,  local or
foreign  government  that may be applicable  to the  debentures or the shares of
common stock.

    This summary is based on the Internal Revenue Code of 1986, as amended,  the
Treasury  regulations  promulgated  thereunder and  administrative  and judicial
interpretations thereof, all as of the date hereof, and all of which are subject
to change and differing  interpretations,  possibly on a retroactive  basis.  No
statutory, administrative or judicial authority directly addresses the treatment
of the  debentures or  instruments  similar to the  debentures for United States
federal  income tax  purposes.  Therefore,  there can be no  assurance  that the
Internal Revenue Service (the "IRS") will not successfully challenge one or more
of the conclusions described in this prospectus.

    We urge prospective  investors to consult their tax advisors with respect to
the tax  consequences to them of the purchase,  ownership and disposition of the
debentures  and the  shares  of common  stock in light of their  own  particular
circumstances,  including the tax consequences under state,  local,  foreign and
other tax laws and the possible  effects of changes in United States federal and
other tax laws.

Classification of the Debentures

    Pursuant  to the  terms of the  Indenture,  each  holder  of the  debentures
agreed,  for United States federal income tax purposes,  to treat the debentures
as  indebtedness  for United States federal  income tax purposes  subject to the
regulations governing contingent payment debt instruments and to be bound by our
application of those regulations to the debentures,  including our determination
of the rate at which  interest  will be deemed to accrue on the  debentures  for
United  States  federal  income tax purposes.  The remainder of this  discussion
assumes that the  debentures  will be treated in accordance  with that agreement
and our  determinations.  However,  the proper  application  of the  regulations
governing  contingent  payment  debt  instruments  to a holder of a debenture is
uncertain  in a number of respects,  and no assurance  can be given that the IRS
will not assert that the debentures  should be treated  differently or that such
an assertion would not prevail.  Such treatment could affect the amount,  timing
and  character  of  income,  gain or loss in  respect  of an  investment  in the
debentures.  In  particular,  it might be  determined  that a holder should have
accrued  interest income at a lower rate,  should not have recognized  income or
gain upon the conversion, and should have recognized capital gain upon a taxable
disposition of its debentures.

U.S. Holders

    Under the rules governing contingent payment debt instruments, a U.S. Holder
will generally be required to accrue interest  income on the debentures,  in the
amounts described below,  regardless of whether the U.S. Holder uses the cash or
accrual  method of tax  accounting.  Accordingly,  U.S.  Holders  will likely be
required  to include  interest  in taxable  income in each year in excess of the
accruals on the debentures for non-tax  purposes and in excess of any contingent
interest payments actually received in that year.

                                       30


    A U.S.  Holder must  accrue on its  debentures  an amount of original  issue
discount as ordinary  income for United States federal income tax purposes,  for
each accrual  period prior to and including the maturity date of the  debentures
that equals:

    o   the product of (i) the  adjusted  issue price (as defined  below) of the
        debentures  as of the  beginning  of the  accrual  period;  and (ii) the
        comparable  yield to  maturity  (as  defined  below) of the  debentures,
        adjusted for the length of the accrual period;

    o   divided by the number of days in the accrual period; and

    o   multiplied by the number of days during the accrual period that the U.S.
         Holder held the debentures.

    The "issue  price" of a debenture is the first price at which a  substantial
amount of the debentures is sold to the public,  excluding bond houses,  brokers
or similar  persons or  organizations  acting in the  capacity of  underwriters,
placement agents or wholesalers.  The adjusted issue price of a debenture is its
issue price  increased by any interest  income  previously  accrued,  determined
without  regard to any  adjustments  to interest  accruals  described  below and
decreased  by  the  projected  amounts  of  any  payments  with  respect  to the
debentures.

    Under  the rules  governing  contingent  payment  debt  instruments,  we are
required  to  establish  the  "comparable  yield"  for the  debentures.  We have
determined  that the comparable  yield for the debentures is the annual yield we
would incur, as of the initial issue date, on a fixed rate  nonconvertible  debt
security with no contingent  payments,  but with terms and conditions  otherwise
comparable to those of the  debentures  including the absence of  subordination,
term,  timing of payments  and general  market  conditions,  but  excluding  any
adjustments for liquidity or the riskiness of the contingencies  with respect to
the  debentures.  Accordingly,  we have  determined the  comparable  yield to be
8.543% compounded semiannually.

    We are required to provide to U.S. Holders, solely for United States federal
income tax  purposes,  a schedule  of the  projected  amounts of payments on the
debentures.  This schedule must produce the comparable  yield. Our determination
of the projected  payment  schedule for the  debentures  includes  estimates for
payments of contingent interest and an estimate for a payment at maturity taking
into  account the  conversion  feature.  U.S.  Holders may obtain the  projected
payment schedule by submitting a written request for it to us at the address set
forth in "Where You Can Find More Information."

    THE  COMPARABLE  YIELD  AND  THE  SCHEDULE  OF  PROJECTED  PAYMENTS  ARE NOT
    DETERMINED  FOR ANY  PURPOSE  OTHER  THAN  FOR THE  DETERMINATION  OF A U.S.
    HOLDER'S  INTEREST  ACCRUALS  AND  ADJUSTMENTS  THEREOF  IN  RESPECT  OF THE
    DEBENTURES  FOR  UNITED  STATES  FEDERAL  INCOME  TAX  PURPOSES  AND  DO NOT
    CONSTITUTE A  PROJECTION  OR  REPRESENTATION  REGARDING  THE ACTUAL  AMOUNTS
    PAYABLE TO U.S. HOLDERS OF THE DEBENTURES.

Adjustments to Interest Accruals on the Debentures

    If a U.S.  Holder receives actual payments with respect to the debentures in
a taxable  year that in the  aggregate  exceed  the  total  amount of  projected
payments  for that taxable  year,  the U.S.  Holder would incur a "net  positive
adjustment" equal to the amount of such excess.  The U.S. Holder would treat the
"net positive  adjustment" as additional  interest  income for the taxable year.
For this  purpose,  the payments in a taxable year include the fair market value
of property received in that year.

    If a U.S.  Holder receives actual payments with respect to the debentures in
a taxable year that in the  aggregate  are less than the amount of the projected
payments  for that taxable  year,  the U.S.  Holder would incur a "net  negative
adjustment" equal to the amount of such deficit. This adjustment will (a) reduce
the U.S.  Holder's  interest income on the debentures for that taxable year, and
(b) to the extent of any excess after the  application  of (a),  give rise to an
ordinary loss to the extent of the U.S. Holder's income on the debentures during
prior taxable years, reduced to the extent such interest was offset by prior net
negative adjustments.

Sale, Exchange, Conversion or Redemption

    Generally,  the sale or  exchange of a  debenture,  or the  redemption  of a
debenture  for cash,  will result in taxable gain or loss to a U.S.  Holder.  In
addition,  as described  above,  our calculation of the comparable yield and the
schedule of projected payments for the debentures includes the receipt of common
stock upon  conversion  of a  debenture  into  shares of our  common  stock as a
contingent  payment with respect to the  debentures.  Accordingly,  we intend to
treat the receipt of our common stock by a U.S.  Holder upon the conversion of a
debenture,  or upon  the  redemption  of a  debenture  where we elect to pay the
redemption  price in shares of our common  stock,  as a contingent  payment.  As
described  above,  holders  are  generally  bound  by our  determination  of the

                                       31




comparable yield and the schedule of projected payments. Under this treatment, a
sale or  exchange,  or such a  conversion  or  redemption,  also will  result in
taxable gain or loss to the U.S. Holder. The amount of gain or loss on a taxable
sale,  exchange,  conversion or redemption will equal the difference between (a)
the amount of cash plus the fair market value of any other property  received by
the U.S.  Holder,  including the fair market value of any common stock received,
and (b) the U.S. Holder's adjusted tax basis in the debentures.  A U.S. Holder's
adjusted  tax basis in a  debenture  on any date  generally  will equal the U.S.
Holder's original  purchase price for the debentures,  increased by any original
issue discount  previously accrued by the U.S. Holder (determined without regard
to any positive or negative  adjustments to interest accruals  described above),
and  decreased  by  the  amount  of any  projected  payments  on the  debentures
projected  to have been made  through that date.  Gain  recognized  upon a sale,
exchange,  conversion or redemption of a debenture  generally will be treated as
ordinary  interest  income;  any loss  will be  ordinary  loss to the  extent of
interest previously included in income, and thereafter, capital loss (which will
be long-term if the debenture is held for more than one year). The deductibility
of net capital losses is subject to limitations.

    A U.S.  Holder's  tax basis in shares of our common  stock  received  upon a
conversion  of a  debenture  or upon a holder's  exercise of a put right that we
elect to pay in shares of our  common  stock will  equal the then  current  fair
market value of such common  stock.  The U.S.  Holder's  holding  period for the
shares of our common stock  received  will commence on the day after the date of
conversion or redemption.

Purchasers of Debentures at a Price Other Than the Adjusted Issue Price

    A U. S. Holder that  purchases  debentures  in the  secondary  market for an
amount that differs from the adjusted  issue price of the debentures at the time
of purchase will be required to accrue  interest income on the debentures in the
same manner as a U.S. Holder that purchased  debentures in the initial offering.
A U.S. Holder must also reasonably  allocate any difference between the adjusted
issue price and the U.S.  Holder's  basis in the debentures to daily portions of
interest or projected payments over the remaining term of the debentures. If the
purchase price of the  debentures is greater than the adjusted issue price,  the
amount of the  difference  allocated  to a daily  portion  of  interest  or to a
projected  payment is treated as a  "negative  adjustment"  on the day the daily
portion accrues or the payment is made,  respectively.  If the purchase price of
the  debentures  is less  than the  adjusted  issue  price,  the  amount  of the
difference allocated to a daily portion of interest or to a projected payment is
treated as a "positive  adjustment" on the day the daily portion  accrues or the
payment is made,  respectively.  Any such negative or positive  adjustment  will
decrease or increase,  respectively, the U.S. Holder's adjusted tax basis in the
debentures.

    Certain U.S. Holders will receive Forms 1099-OID reporting interest accruals
on their debentures.  Those forms will not reflect the effect of any positive or
negative adjustments  resulting from the U.S. Holder's purchase of debentures in
the  secondary  market at a price  different  from  adjusted  issue price of the
debentures on the date of purchase.  U.S. Holders are urged to consult their tax
advisors as to whether,  and how, such adjustments  should be taken into account
in determining their interest accruals with regard to the debentures.

Distributions on Common Stock

    If a U.S. Holder converts the debentures into shares of our common stock, in
general,  distributions  on the shares of our common  stock that are paid out of
our current or  accumulated  earnings and profits,  as defined for United States
federal income tax purposes, will constitute dividends and will be includible in
income by a holder and taxable as ordinary  income when received or accrued,  in
accordance  with that holder's  method of accounting  for United States  federal
income tax  purposes.  If a  distribution  exceeds our  current and  accumulated
earnings and profits,  the excess will be treated first as a tax-free  return of
the U.S. Holder's investment, up to the U.S. Holder's basis in the shares of our
common stock. Any remaining excess will be treated as capital gain.

Constructive Dividends

    If at any time we make a distribution of property to our  stockholders  that
would be taxable to the  stockholders  as a dividend for United  States  federal
income tax purposes and, in accordance with the anti-dilution  provisions of the
debentures,  the conversion  rate of the debentures is increased,  such increase
may be  deemed  to be the  payment  of a  taxable  dividend  to  holders  of the
debentures.

    For example,  an increase in the exchange rate in the event of  distribution
of our evidences of indebtedness or our assets or an increase in the event of an
extraordinary  cash dividend will generally result in deemed dividend  treatment
to holders of the debentures, but an increase in the event of stock dividends or
the distribution of rights to subscribe for our common stock generally will not.

                                       32



Treatment of Non-U.S. Holders

    The rules  governing  United  States  federal  income  taxation  of Non-U.S.
Holders are complex and no attempt  will be made in this  prospectus  to provide
more than a summary of such rules.  Non-U.S.  Holders  should consult with their
tax advisors to determine the effect of United States federal,  state, local and
foreign  income tax laws,  as well as treaties,  with regard to an investment in
the  debentures  and  shares  of  our  common  stock,  including  any  reporting
requirements.

Payments Made With Respect to the Debentures

    The 30% United States federal  withholding tax will not apply to any payment
to a Non-U.S.  Holder of principal  or interest  (including  amounts  taken into
income as  interest  under the  accrual  rules  described  above  under "-- U.S.
Holders" and amounts  attributable  to the shares of our common  stock  received
upon a conversion of the  debentures)  on  debentures,  provided  that:  (i) the
Non-U.S.  Holder does not own,  actually or  constructively,  10% or more of the
total combined voting power of our common stock, (ii) the Non-U.S. Holder is not
a controlled foreign corporation related,  directly or indirectly, to us through
stock  ownership;  (iii) the  Non-U.S.  Holder is not a bank which  acquired the
debentures in  consideration  for an extension of credit made pursuant to a loan
agreement entered into in the ordinary course of business; (iv) our common stock
is  actively  traded  within the  meaning of Section  871(h)(4)(C)(v)(I)  of the
Internal  Revenue Code;  and (v) either (a) the  beneficial  owner of debentures
certifies  to us or our paying  agent on IRS Form  W-8BEN,  under  penalties  of
perjury,  that it is not a United States  person and provides its name,  address
and certain other  information or (B) the beneficial  owner holds its debentures
through certain foreign  intermediaries or certain foreign partnerships and such
holder satisfies certain certification requirements.

    If the Non-U.S.  Holder cannot  satisfy the  requirements  described  above,
payments  of interest  (including  amounts  taken into income  under the accrual
rules  described  above under "-- U.S.  Holder" and amounts  attributable to our
common stock  received upon a conversion of the  debentures)  will be subject to
the 30%  United  States  federal  withholding  tax unless  the  Non-U.S.  Holder
provides us with a properly  executed  (1) IRS Form W-8BEN (or  successor  form)
claiming an exemption from or reduction in  withholding  under an applicable tax
treaty or (2) IRS Form W-8ECI (or successor  form) stating that interest paid on
the  debentures  is not subject to  withholding  tax  because it is  effectively
connected  with the  Non-U.S.  Holder's  conduct of a trade or  business  in the
United States.

    If a Non-U.S.  Holder of the debentures is engaged in a trade or business in
the United States,  and if interest on the  debentures is effectively  connected
with the conduct of such trade or business, the Non-U.S. Holder, although exempt
from the withholding tax discussed in the preceding  paragraphs,  will generally
be subject to regular  United States  federal  income tax on interest and on any
gain realized on the sale,  exchange  conversion  of the  debentures in the same
manner as if it were a U.S. Holder.  Such a Non-U.S.  Holder will be required to
provide  to the  withholding  agent a  properly  executed  IRS Form  W-8ECI  (or
successor  form)  in  order  to claim an  exemption  from  withholding  tax.  In
addition,  if such a Non-U.S.  Holder is a foreign  corporation,  such  Non-U.S.
Holder may be subject  to a branch  profits  tax equal to 30% (or such lower tax
rate provided by an applicable treaty) of its effectively connected earnings and
profits for the taxable year, subject to certain adjustments.

Sale or Exchange of Debentures or Common Stock

    A Non-U.S.  Holder will not  generally be subject to United  States  federal
income or withholding tax with respect to gain upon the sale,  exchange or other
disposition  (other than a conversion  or a  redemption)  of the  debentures  or
shares of our common  stock,  unless:  (1) the income or gain is "U.S.  trade or
business income," which means income or gain that is effectively  connected with
the conduct by the Non-U.S.  Holder of a trade or business, or, in the case of a
treaty resident,  attributable to a permanent  establishment or a fixed base, in
the United States;  (2) such Non-U.S.  Holder is an individual who is present in
the United  States for 183 days or more in the taxable year of  disposition  and
certain other  conditions  are met; (3) such  Non-U.S.  Holder is subject to tax
pursuant to the  provisions of the Internal  Revenue Code  applicable to certain
United States expatriates; or (4) in the case of an amount which is attributable
to original issue discount, the Non-U.S. Holder does not meet the conditions for
exemption from United States federal withholding tax described above.

    U.S.  trade or  business  income  of a Non-U.S.  Holder  will  generally  be
subject to regular  United States federal income tax in the same manner as if it
were realized by a U.S.  Holder.  A Non-U.S.  Holder that realizes U.S. trade or
business  income with respect of the  debentures or common stock should  consult
their tax advisors as to the treatment of such income or gain. In addition, U.S.
trade or  business  income of a Non-U.S.  Holder  that is a  corporation  may be
subject to a branch profits tax at a rate of 30%, or such lower rate provided by
an applicable income tax treaty.

                                       33


Distributions on Common Stock

    A Non-U.S. Holder of shares of our common stock will generally be subject to
United States  federal  income or  withholding  tax at a 30% rate (or lower rate
provided under any  applicable  income tax treaty) on  distributions  by us with
respect to our common stock that are treated as dividends paid (and on dividends
deemed paid on the  debentures or common stock,  as described  above under "U.S.
Holders-Constructive  Dividends").  Except to the extent that an applicable  tax
treaty otherwise provides, a Non-U.S. Holder generally will be taxed in the same
manner as a U.S.  Holder on dividends paid (or deemed paid) that are effectively
connected  with the  Non-U.S.  Holder's  conduct of a trade or  business  in the
United States,  and a Non-U.S.  Holder that is a corporation may also be subject
to a United States branch profits tax at a 30% rate or such lower rate as may be
specified in an applicable income tax treaty.

Foreign Investment in Real Property Tax Act

    Under the  Foreign  Investment  in Real  Property  Tax Act,  any  person who
acquires a "United  States real property  interest" (as described  below) from a
foreign  person  must  deduct  and  withhold  a tax  equal to 10% of the  amount
realized by the foreign transferor.  In addition, a foreign person that disposes
of a United  States real  property  interest is generally  required to recognize
gain or loss that is  subject to United  States  federal  income  tax. A "United
States real property  interest"  generally  includes any interest (other than an
interest  solely as a  creditor)  in a United  States  corporation  unless it is
established  under specific  procedures that the corporation is not (and was not
for  the  prior  five-year  period)  a  "United  States  real  property  holding
corporation."  We do not believe  that we are or have been a United  States real
property  holding  corporation as of the date hereof,  nor do we believe that we
have been a United States real property  holding  corporation at any time during
the past five years.  We cannot,  however,  give any assurance  that we will not
become a United States real property holding  corporation in the future. Our tax
counsel  has  rendered  no opinion as to whether we are,  at any time during the
past five years have been,  or will in the future  become,  a United States real
property holding corporation.  If it is determined that we are, have been in the
past five years or in the future become,  a United States real property  holding
corporation,  as  long  as our  stock  is  regularly  traded  on an  established
securities  market,  an exemption  should apply to the debentures and our common
stock  except (i) in the case of  debentures,  if the  debentures  are or become
regularly  traded,  with respect to a Non-U.S.  Holder that owns more than 5% of
the  debentures,  and (ii)  otherwise,  and in the case of  common  stock,  with
respect to a Non-U.S.  Holder whose beneficial and/or constructive  ownership of
the  debentures or common stock exceeds 5% of the total fair market value of our
common stock.

    Any  investor  that  may  approach  or  exceed  the 5%  ownership  threshold
discussed above,  either along or in conjunction  with related  persons,  should
consult its own tax advisor  concerning  the United  States  federal  income tax
consequences that may result. A Non-U.S. Holder that sells or otherwise disposes
of debentures or common stock may be required to inform its  transferee  whether
such  debentures  or common  stock  constitutes  a United  States real  property
interest.

Back-up Withholding and Information Reporting

U.S. Holders

    Payments of interest or dividends made by us on, or the proceeds of the sale
or other  disposition  of, the  debentures  or shares of our common stock may be
subject to information  reporting and United States  federal backup  withholding
tax at the rate then in effect if the  recipient of such payment fails to supply
an accurate  taxpayer  identification  number or otherwise  fails to comply with
applicable United States  information  reporting or certification  requirements.
Any  amount  withheld  from  a  payment  to an  U.S.  Holder  under  the  backup
withholding  rules is allowable as a credit  against the holder's  United States
federal income tax,  provided that the required  information is furnished to the
IRS.

Non-U.S. Holders

    A Non-U.S. Holder may be required to comply with certification procedures to
establish  that the  holder  is not a U.S.  person  in  order  to  avoid  backup
withholding  tax  requirements  with respect to our  payments of  principal  and
interest,  including  cash payments in respect of original issue discount on the
debentures,  or the proceeds of the sale or other disposition of the debentures.
In addition, we must report annually to the IRS and to each Non-U.S.  Holder the
amount of any  dividends  paid to, and the tax  withhold  with  respect to, such
holder,  regardless  of whether any tax was actually  withheld.  Copies of these
information  returns  may  also be made  available  under  the  provisions  of a
specific  treaty or agreement to the tax authorities of the country in which the
Non-U.S. Holder resides.

                                       34



Tax Event

    The modification of the terms of the debentures by us upon a Tax Event could
possibly  alter the amount and timing of income  recognition by the holders with
respect to the payments of interest due after the option exercise date.

THE PROPER TAX TREATMENT OF A HOLDER OF THE DEBENTURES IS HIGHLY  UNCERTAIN IN A
NUMBER OF RESPECTS.  HOLDERS  SHOULD  CONSULT  THEIR TAX ADVISORS  REGARDING THE
UNITED  STATES  FEDERAL,  STATE,  LOCAL  AND  FOREIGN  TAX  CONSEQUENCES  OF  AN
INVESTMENT IN THE  DEBENTURES  AND WHETHER AN  INVESTMENT  IN THE  DEBENTURES IS
ADVISABLE IN LIGHT OF THE AGREED UPON TAX TREATMENT AND THE HOLDER'S  PARTICULAR
TAX SITUATION.


                                       35




                             SELLING SECURITYHOLDERS

    The debentures were originally issued by us and sold by Salomon Smith Barney
Inc.  in  a  transaction  exempt  from  the  registration  requirements  of  the
Securities Act to persons reasonably believed by Salomon Smith Barney Inc. to be
"qualified  institutional  buyers" (as defined by Rule 144A under the Securities
Act).

     Set forth below are the names of each selling securityholder, the principal
amount of debentures  that may be offered by each selling  securityholder  under
this  prospectus,   each  selling  securityholder's  percentage  of  outstanding
debentures,  and the number of shares of common stock into which the  debentures
are convertible,  and the percentage of total common stock  outstanding for each
selling  stockholder,  received by us as of October 5, 2001. None of the selling
securityholders  have  held any  principal  position,  office  or had any  other
material relationship within the past three years with us or our predecessors or
affiliates.

     The  following  table  sets forth  certain  information  received  by us in
response to questionnaires  received from the selling  securityholders  named in
the table on or prior to October 5, 2001. However,  any or all of the debentures
or common stock listed  below may be offered for sale under this  prospectus  by
the selling securityholders from time to time and the number of shares of common
stock into which the  debentures  are  convertible  is subject to adjustment and
therefore  could  change.   Accordingly,  we  cannot  estimate  the  amounts  of
debentures or common stock that will be held by the selling securityholders upon
consummation of any sales.

     The  inclusion in the table of the  individuals  named therein shall not be
deemed to be an admission that any such individuals are our "affiliates."

(1)  Assumes  conversion of all of the holder's  debentures at a conversion rate
     of 14.7167 shares of common stock per $1,000  principal  amount at maturity
     of the  debentures,  rounded  down to the nearest  whole  number of shares.
     However,  this  conversion rate is subject to adjustment as described under
     "Description of Debentures - Conversion Rights." As a result, the amount of
     common stock  issuable upon  conversion of the  debentures  may increase or
     decrease in the future.

(2)  Calculated based on Rule 13d-3(d)(i) of the Exchange Act using  340,351,333
     shares of common stock outstanding as of October 3, 2001.  Pursuant to that
     rule, in calculating this amount for each holder, we treated as outstanding
     the number of shares of common stock  issuable  upon  conversion  of all of
     that  holder's  debentures  but  did not  assume  conversion  of any  other
     holder's debentures.

(3)  The TIERS(R)  Fixed Rate  Certificates  Trust Series 2001-14 (the "TIERS(R)
     Trust") holds these debentures in trust as part of its TIERS(R) program.

(4)  Information  about  other  selling  securityholders  will be set  forth  in
     prospectus supplements or in other documents that we file from time to time
     with the SEC that are  incorporated  by reference in this  prospectus  (see
     "Where You Can Find More Information" above), if required.

      This  prospectus  also covers any  additional  shares of common stock that
become  issuable in connection  with the debentures and underlying  common stock
being registered by reason of any stock dividend, stock split,  recapitalization
or other similar transaction effected without the receipt of consideration which
results in an increase in the number of our outstanding shares of common stock.


                                  UNDERWRITERS

         The  SEC  staff  is of a view  that  selling  securityholders  who  are
registered  broker-dealers  or affiliates of  registered  broker-dealers  may be
underwriters under the Securities Act. Salomon Smith Barney Inc. is a registered
broker-dealer.  UBS  AG  is  an  affiliate  of a  registered  broker-dealer.  No
compensation  will be paid and no discounts or commissions  will be given to any
underwriter  in  connection  with  the  securities   being  registered  in  this
registration statement.


                              PLAN OF DISTRIBUTION

      We are registering the debentures and associated common stock on behalf of
the  selling  securityholders.  As used in this  prospectus,  the term  "selling
securityholders" includes pledgees,  transferees or other successors-in-interest
selling  debentures  or the  associated  common stock  received from the selling
securityholders   as   pledgors,   borrowers   or  in   connection   with  other
non-sale-related  transfers after the date of this  prospectus.  This prospectus
may  also be used  by  transferees  of the  selling  securityholders,  including
broker-dealers or other transferees who borrow or purchase the debentures or the
associated  common  stock to settle or close out short sales of shares of common
stock.  The  selling  securityholders  will act  independently  of us in  making
decisions with respect to the timing,  manner, and size of each sale or non-sale
related transfer. We will not receive any of the proceeds of this offering.

     The selling  securityholders may sell debentures or associated common stock
directly to purchasers from time to time.  Alternatively,  they may from time to
time offer the debentures or associated common stock to or through underwriters,
broker-dealers  or  agents,  who  may  receive   compensation  in  the  form  of
underwriting   discounts,   concessions   or   commissions   from  the   selling
securityholders  or the  purchasers of such  securities for whom they may act as
agents.  The selling  securityholders  and any  underwriters,  broker-dealers or
agents that  participate  in the  distribution  of the  debentures or associated
common  stock may be deemed  to be  "underwriters"  within  the  meaning  of the
Securities Act and any profit on the sale of such  securities and any discounts,
commissions, concessions or other compensation received by any such underwriter,
broker-dealer  or  agent  may  be  deemed  to  be  underwriting   discounts  and
commissions  under  the  Securities  Act.  We know of no  existing  arrangements
between  any  selling  securityholder  and  any  other  selling  securityholder,
underwriter,  broker-dealer  or other agent relating to the sale or distribution
of the debentures or associated  common stock. No underwriter,  broker-dealer or
agent  has  been  engaged  by us in  connection  with  the  distribution  of the
debentures or associated common stock.

     Because  the  selling  securityholders  may be deemed to be  "underwriters"
within the meaning of the Securities  Act, the selling  securityholders  will be
subject to the prospectus delivery requirements of the Securities Act.

                                       37


      The debentures  and the  associated  common stock may be sold from time to
time in one or more  transactions  at fixed  prices,  which may be  changed,  at
prevailing  market prices at the time of sale, at varying  prices  determined at
the  time  of sale or at  negotiated  prices.  The  sale of the  debentures  and
associated common stock may be effected by means of one or more of the following
transactions (which may involve crosses or block transactions):

      o  on any  national  securities  exchange,  such  as the  New  York  Stock
         Exchange,  or quotation service on which the debentures or common stock
         may be listed or quoted at the time of sale,

      o  in the over-the-counter market,

      o  in transactions otherwise than on such exchanges or services or in the
         over-the-counter market,

      o  through the purchase and sale of over-the-counter options, or

      o  through at-the-market offerings as defined by Rule 415(a)(4) of the
         Securities Act.

      In connection with sales of the debentures and the associated common stock
or otherwise,  the selling  securityholders may enter into hedging  transactions
with  broker-dealers,  which may in turn engage in short sales of the debentures
and the  associated  common  stock in the course of hedging the  positions  they
assume. The selling  securityholders may also sell debentures and the associated
common stock short and deliver  debentures  and the  associated  common stock to
close out such short positions,  or loan or pledge  debentures to broker-dealers
that in turn may sell such securities.

      At the time a particular  offering of the  debentures  and the  associated
common stock is made, a prospectus supplement,  if required, will be distributed
which will set forth the aggregate  amount of  debentures  or associated  common
stock being offered and the terms of the  offering,  including the name or names
of any underwriters,  broker-dealers or agents,  any discounts,  commissions and
other terms constituting  compensation from the selling  securityholders and any
discounts,   commissions  or  concessions   allowed  or  reallowed  or  paid  to
broker-dealers.

      To  comply  with  the  securities  laws  of  certain   jurisdictions,   if
applicable,  the debentures  and the associated  common stock will be offered or
sold in such  jurisdictions  only  through  registered  or  licensed  brokers or
dealers.

      The selling  securityholders  will be subject to applicable  provisions of
the Exchange Act and the rules and regulations thereunder,  which provisions may
limit the timing of purchases and sales of any of the  debentures by the selling
securityholders. The foregoing may affect the marketability of such securities.

      All expenses of the  registration  of the  debentures  and the  associated
common  stock  will  be  paid  by  us;  provided,   however,  that  the  selling
securityholders will pay all underwriting discounts and selling commissions,  if
any. The selling securityholders will be indemnified by us against certain civil
liabilities,  including certain  liabilities under the Securities Act or will be
entitled to contribution in connection therewith.  We will be indemnified by the
selling securityholders  severally against certain civil liabilities,  including
certain   liabilities   under  the  Securities  Act,  or  will  be  entitled  to
contribution in connection therewith.

      We cannot assure you that the selling securityholders will sell all or any
of the debentures or associated common stock offered by this prospectus.

                                  LEGAL MATTERS

     The valid  issuance  of the  debentures  and the  associated  common  stock
offered  hereby  will be  passed  on for us by  Gibson,  Dunn &  Crutcher,  LLP,
Washington,  D.C. Skadden,  Arps, Slate, Meagher & Flom LLP, New York, New York,
which  acted  as  special  counsel  in  the  initial  private  placement  of the
debentures  and provided  additional  advice  regarding the debentures and legal
opinions on the validity of the debentures  and the associated  common stock and
certain  tax  matters,   will  pass  upon  certain  tax  matters  regarding  the
debentures.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Our restated  certificate of incorporation  provides that no director shall
be liable to us or our stockholders for monetary damages for breach of fiduciary
duty as a  director,  except as required by law, as in effect from time to time.
Currently, Delaware law requires that liability be imposed for the following:

o  any breach of the director's duty of loyalty to our company or our
   stockholders;

o  any act or omission not in good faith or which involved intentional
   misconduct or a knowing violation of law;

o  unlawful payments of dividends or unlawful stock repurchases or redemptions
   as provided in Section 174 of the Delaware General Corporate Law; and

o  any transaction from which the director derived an improper personal benefit.

     Our bylaws  provide that, to the fullest  extent  permitted by law, we will
indemnify  any  person  made or  threatened  to be made a party to any action by
reason of the fact that the person is or was our director or officer,  or served
any other enterprise at our request as a director or officer.  We will reimburse
the expenses,  including  attorneys' fees,  incurred by a person  indemnified by
this  provision  when we receive an  undertaking  to repay such amounts if it is
ultimately  determined  that the person is not entitled to be indemnified by us.
Amending this provision will not reduce our indemnification obligations relating
to actions taken before an amendment.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933,  as  amended,  may be  permitted  to  directors,  officers  or  persons
controlling the registrant pursuant to the foregoing  provision,  the registrant
has been informed that in the opinion of the Securities and Exchange  Commission
such  indemnification  is against  public  policy as expressed in the Act and is
therefore unenforceable.

ITEM 17.  UNDERTAKINGS


A.    Rule 415 Offering.  The undersigned registrant hereby undertakes:

(1)     To file, during any period in which offers or sales are being made, a
        post-effective amendment to this registration
        statement:

(i)     To include any prospectus required by Section 10(a)(3) of the Securities
        Act;

(ii)    To reflect in the prospectus any facts of events arising after the
        effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) under the Securities Act if,
        in the aggregate, the changes in volume and price present no more than a
        20% change in the maximum aggregate offering price set forth in the
        "Calculation of Registration Fee" table in the effective registration
        statement; and

(iii)   To include any material  information  with respect to the plan of
        distribution  not previously  disclosed in the registration statement or
        any material  change to such  information in the registration statement.

        Provided,  however,  the paragraphs  (1)(i) and (1)(ii) do not apply if
        the information  required to be included in a post-effective  amendment
        by those  paragraphs  is  contained in periodic  reports  filed with or
        furnished to the Commission by the Registrant pursuant to Section 13 or
        15(d) of the Securities  Exchange Act of 1934 that are  incorporated by
        reference in the registration statement.


                                       41


(2)     That, for the purpose of determining any liability under the Securities
        Act,  each such  post-effective  amendment  shall be deemed to be a new
        registration  statement relating to the securities offered therein, and
        the offering of such  securities  at the time shall be deemed to be the
        initial bona fide offering thereof;

(3)     To remove from registration by means of a post-effective amendment any
        of the securities being registered which remain unsold at the
        termination of the offering;

(4)     That,  for purposes of determining  any liability  under the Securities
        Act, each filing of the Registrant's  annual report pursuant to Section
        13(a)  or  15(d)  of the  Securities  Exchange  Act  of  1934  that  is
        incorporated  by  reference  in this  registration  statement  shall be
        deemed to be a new  registration  statement  relating to the securities
        offered therein, and the offering of such securities at that time shall
        be deemed to be the initial bona fide offering thereof;

(5)     To file an application  for the purpose of determining  the eligibility
        of the trustee to act under  subsection (a) of Section 310 of the Trust
        Indenture  Act of 1939 in  accordance  with the rules  and  regulations
        prescribed  by the  Commission  under  Section  305(b)(2)  of the Trust
        Indenture Act of 1939;

(6)     That,  for purposes of determining  any liability  under the Securities
        Act of 1933, the information  omitted from the form of prospectus filed
        as part of this  registration  statement in reliance upon Rule 430A and
        contained in a form of prospectus  filed by the registrant  pursuant to
        Rule  424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall
        be deemed to be part of this  registration  statement as of the time it
        was declared effective; and

(7)     Insofar as indemnification for liabilities arising under the Securities
        Act may be permitted to directors,  officers and controlling persons of
        the  Registrant  pursuant to the  provisions  referred to in Item 15 of
        this  registration  statement,  or otherwise,  the  Registrant has been
        advised that in the opinion of the Securities  and Exchange  Commission
        such  indemnification  is against  public  policy as  expressed  in the
        Securities Act and is,  therefore,  unenforceable.  In the event that a
        claim for  indemnification  against  such  liabilities  (other than the
        payment by the  Registrant of expenses  incurred or paid by a director,
        officer  or  controlling  person of the  Registrant  in the  successful
        defense of any action, suit or proceeding) is asserted by such director
        officer or controlling  person in connection with the securities  being
        registered,  the Registrant will,  unless in the opinion of its counsel
        the matter has been settled by controlling precedent, submit to a court
        of appropriate  jurisdiction the question whether such  indemnification
        by it is against  public policy as expressed in the  Securities Act and
        will be governed by the final adjudication of such issue.

                                       42
