<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This Prospectus Supplement and the accompanying Prospectus contain both historical and forward-looking statements within the meaning of
Section&nbsp;27A of the United&nbsp;States Securities Act of 1933, as amended (the&nbsp;"</FONT><FONT SIZE=2><B>U.S.&nbsp;Securities Act</B></FONT><FONT SIZE=2>"), and Section&nbsp;21E of
the United&nbsp;States Securities Exchange Act of 1934, as amended (the&nbsp;"</FONT><FONT SIZE=2><B>U.S.&nbsp;Exchange Act</B></FONT><FONT SIZE=2>"). All forward-looking statements are based
on TransAlta's beliefs as well as assumptions based on information available at the time the assumption was made and on management's experience and perception of historical trends, current conditions
and expected further developments as well as other factors deemed appropriate in the circumstances. Forward-looking statements are not facts, but only predictions and generally can be identified by
the use of statements that include phrases such as "may", "will", "believe", "expect", "anticipate", "intend", "plan", "foresee", "potential", "enable", "continue" or other comparable terminology.
These statements are not guarantees of TransAlta's future performance and are subject to risks, uncertainties and other important factors that could cause TransAlta's actual performance to be
materially different from those projected. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With
respect to forward-looking statements contained in this Prospectus Supplement, we have made assumptions regarding, among other things: our ability to close this offering on a timely

cash flow from operating and contracting activities; estimates of fuel supply and demand conditions and the costs of procuring fuel; expectations for demand for electricity in both the short term and
long term, and the resulting impact on electricity prices; the impact of load growth, increased capacity, and natural gas costs on power prices; expectations in respect of generation availability,
capacity and production; expectations regarding the role different energy sources will play in meeting future energy needs; expected financing of our capital expenditures; expected governmental
regulatory regimes and legislation and their expected impact on us and the timing of the implementation of such regimes and regulations, as well as the cost of complying with resulting regulations and
laws; our expectations relating to
the FERC's approval of our California settlement and the outcome of proceedings before the AUC; our trading strategies and the risk involved in these strategies; estimates of future tax rates, future

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TransAlta is a corporation amalgamated under the </FONT><FONT SIZE=2><I>Canada Business Corporations Act</I></FONT><FONT SIZE=2>. The
registered office and principal place of business of TransAlta are located at 110-12<SUP>th</SUP>&nbsp;Avenue S.W., Calgary, Alberta, Canada, T2R&nbsp;0G7. For further information on the
intercorporate relationships among TransAlta and its subsidiaries, please see "</FONT><FONT SIZE=2><I>Corporate Structure"</I></FONT><FONT SIZE=2> in the Annual Information&nbsp;Form. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TransAlta
and its predecessors have been engaged in the production and sale of electric energy since 1909. The Corporation is among Canada's largest non-regulated electric generation and
energy marketing companies with an aggregate net ownership interest of approximately 8,833&nbsp;megawatts ("</FONT><FONT SIZE=2><B>MW</B></FONT><FONT SIZE=2>") of generating capacity operating in
facilities having approximately 11,095&nbsp;MW of aggregate generating capacity<SUP>(1)</SUP>. The
Corporation is focused on generating electricity in Canada, the United&nbsp;States and Australia through its diversified portfolio of facilities fuelled by coal, natural gas, hydroelectric and
geothermal resources. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
Canada, excluding assets under development and restoration, the Corporation holds a net ownership interest of approximately 6,322&nbsp;MW of electrical generating capacity in
thermal, natural gas-fired, wind-powered and hydroelectric facilities, including 5,165&nbsp;MW in Western Canada, 922&nbsp;MW in Ontario, 147&nbsp;MW in Qu&eacute;bec and 88&nbsp;MW in
New&nbsp;Brunswick. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the United&nbsp;States, the Corporation's principal facilities include a 1,340&nbsp;MW thermal facility and a 248&nbsp;MW natural gas-fired facility, both located in Centralia,
Washington, as well as a 1&nbsp;MW hydroelectric facility in Washington, all of which supply electricity to the Pacific Northwest. The Corporation also holds a 101&nbsp;MW net interest in a wind
farm located in Wyoming (the&nbsp;"</FONT><FONT SIZE=2><B>Wyoming Wind Farm</B></FONT><FONT SIZE=2>"). The economic interest in the Wyoming Wind Farm was transferred to TransAlta Renewables in
exchange for approximately US$102&nbsp;million and we maintain a 70.3% direct and indirect ownership interest in TransAlta Renewables. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Corporation also holds a 50&nbsp;percent interest in CE Generation,&nbsp;LLC ("</FONT><FONT SIZE=2><B>CE Generation</B></FONT><FONT SIZE=2>") and Wailuku Holding
Company&nbsp;LLC ("</FONT><FONT SIZE=2><B>Wailuku</B></FONT><FONT SIZE=2>") through which it has an aggregate net ownership interest of approximately 396&nbsp;MW of generating capacity in
geothermal facilities in California, natural gas-fired facilities in Texas, Arizona and New&nbsp;York, and a hydroelectric facility located in Hawaii. We have entered into an agreement to sell our
ownership interest in these holdings to our partner, MidAmerican Renewables. With the exception of Wailuku, we expect to complete the sale during the second quarter of&nbsp;2014. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
Australia, the Corporation has 425&nbsp;MW of net electrical generating capacity from natural gas-fired and diesel-fired generation facilities that are located at customer
mine&nbsp;sites. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Corporation regularly reviews its operations in order to optimize its generating assets and evaluates appropriate growth opportunities. The Corporation has in the past and may in the
future make changes and additions to its fleet of coal, natural gas, hydro, wind and geothermal facilities. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Corporation is organized into three business segments, Generation, Energy Trading and Corporate. The Generation group is responsible for constructing, operating and maintaining our
electricity generation facilities. The Energy Trading group is responsible for the wholesale trading of electricity and other energy-related commodities and derivatives. It is also responsible for the
management of available generating capacity as well as the fuel and transmission needs of the Generation business. Both segments are supported by a Corporate group that provides finance, tax,
treasury, legal, regulatory, environmental, health and safety, sustainable development, corporate communications, government and investor relations, procurement, information technology, risk
management, human resources, internal audit, and other administrative services, including compliance and governance services. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;An investment in the Notes is subject to a number of risks. In addition to the other information contained in and incorporated by
reference into this Prospectus Supplement and the accompanying Prospectus, you should consider carefully the risk factors set forth below and under the heading "Risk Factors" in the accompanying
Prospectus, "Risk Factors" and "Risk Management" in the Annual MD&amp;A and "Risk Factors" in the Annual Information&nbsp;Form. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> There is no public market for the Notes.  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Notes are a new issue of securities for which there is currently no public market. We do not intend to apply for listing of the
Notes on any securities exchange or to arrange for the Notes to be quoted on any automated dealer quotation system. If the Notes are traded after their initial issue, they may trade at a discount from
their initial offering prices, depending on prevailing interest rates, the market for similar securities and other factors, including general economic conditions and our financial
condition. We cannot assure you as to the liquidity of the trading market for the Notes or that a trading market for the Notes will&nbsp;develop. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> Changes in interest rates may cause the market value of the Notes to decline.  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prevailing interest rates will affect the market price or value of the Notes. The market price or value of the Notes may decline as
prevailing interest rates for comparable debt instruments rise, and increase as prevailing interest rates for comparable debt securities decline. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> The Notes are unsecured obligations of the Corporation.  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Notes will be our direct unsecured obligations, ranking equally and </FONT> <FONT SIZE=2><I>pari&nbsp;passu</I></FONT><FONT SIZE=2>, except as to sinking fund or analogous provisions,
 with all of our other unsecured and unsubordinated indebtedness. The Notes will be
effectively subordinated to all indebtedness and other liabilities of our subsidiaries and will be effectively subordinated to all of our existing and future secured indebtedness, to the extent of the
value of the assets securing such secured indebtedness. If we are involved in any bankruptcy, dissolution, liquidation or reorganization, the holders of indebtedness and liabilities of our
subsidiaries would be paid before the holders of Notes receive any amounts due under the Notes and the holders of our secured indebtedness would be paid before the holders of Notes receive any amounts
due under the Notes, to the extent of the value of the assets securing such secured indebtedness. In that event, a holder of Notes may not be able to recover any principal or interest due under
the&nbsp;Notes. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> We may not be able to fulfill our repurchase obligations with respect to the Notes upon a change of&nbsp;control.  </I></B></FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If we experience a Change of Control Triggering Event, we will be required to make an offer to repurchase all outstanding Notes at a
repurchase price equal to 101% of the principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, to the applicable repurchase date. Failure to repurchase, or to make an offer
to repurchase, the Notes would constitute a default under the indenture governing the Notes, which would also constitute a default under certain instruments governing our existing indebtedness. See
"Description of the Notes&nbsp;&#151;&nbsp;Repurchase Upon Change of Control Triggering Event". </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a Change of Control Triggering Event were to occur, we cannot assure you that we would have sufficient funds to repay any Notes that we would be required to offer to repurchase, or to
satisfy any other obligations that would become immediately due and payable under the other instruments governing our indebtedness, as a result of such Change of Control Triggering Event. In order to
satisfy our obligations, we
may attempt to refinance our indebtedness or obtain consents from our other lenders or from the holders of the Notes. We cannot assure you that we would be able to refinance our indebtedness or obtain
such consents on satisfactory terms or at&nbsp;all. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If a Change of Control Triggering Event occurs, unless the Corporation has exercised its right to redeem the Notes as described under
"&#151;&nbsp;Optional Redemption", each holder of Notes will have the right to require the Corporation to purchase all or a portion of such holder's Notes pursuant to the offer
described below (the&nbsp;"</FONT><FONT SIZE=2><B>Change of Control Offer</B></FONT><FONT SIZE=2>"), at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the date of purchase, subject to the rights of holders of Notes on the relevant record date to receive interest due on the relevant interest payment&nbsp;date. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Within
30&nbsp;days following the date upon which the Change of Control Triggering Event occurred, or at the Corporation's option, prior to any Change of Control but after the public
announcement of the pending Change of Control, the Corporation will be required to send, by first class mail, a notice to each holder of Notes, with a copy to the Trustee, which notice will govern the
terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30&nbsp;days nor later than 60&nbsp;days from the date such
notice is mailed, other than as may be required by law (the&nbsp;"</FONT><FONT SIZE=2><B>Change of Control Payment Date</B></FONT><FONT SIZE=2>"). The notice, if mailed prior to the date of
consummation of the Change of Control, will state that the Change of Control Offer is conditional on the Change of Control being consummated on or prior to the Change of Control Payment Date. Holders
of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender their Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of
the Note completed, to the paying agent at the address specified in the notice, or transfer their Notes to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying
agent, prior to the close of business on the third business day prior to the Change of Control Payment&nbsp;Date. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Corporation will not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
definition of Change of Control includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of "all or substantially all" of the assets of
the Corporation and its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase "substantially all", there is no precise established definition of the
phrase under applicable law. Accordingly, the ability of a holder of Notes to require the Corporation to repurchase its Notes as a result of a sale, transfer, conveyance or other disposition of less
than all of the assets of the Corporation and its subsidiaries taken as a whole to another "person" may be uncertain. In addition, a recent Delaware Chancery Court decision raised questions about the
enforceability of provisions, which are similar to those in the Indenture, related to the triggering of a change of control as a result of a change in the composition of a board of directors.
Accordingly, the ability of a holder of Notes to require the Corporation to repurchase its Notes as a result of a change in the composition of the board of directors of the Corporation may
be&nbsp;uncertain. </FONT></P>

from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the
Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Notes are to be accomplished by entries made on the books of
Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Notes, except in the event that
use of the book-entry system for the Notes is discontinued. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To

any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Notes; DTC's records reflect only the identity of the Direct Participants to whose accounts such Notes

certain steps to augment the transmission to them of notices of significant events with respect to the Notes, such as redemptions, tenders, defaults, and proposed amendments to the Notes. For example,
Beneficial Owners of Notes may wish to ascertain that the nominee holding the Notes for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial

Money Market Instrument procedures. Under its usual procedures, DTC mails an "Omnibus Proxy" to the Corporation as soon as possible after the record date. The Omnibus Proxy assigns
Cede&nbsp;&amp;&nbsp;Co.'s consenting or voting rights to those Direct Participants to whose accounts Notes are credited on the record date (identified in a listing attached to the

Participants' accounts upon DTC's receipt of funds and corresponding detail information from the Corporation or the trustee, on payable date in accordance with their respective holdings shown on DTC's
records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with Notes held for the accounts of customers in bearer form or

(the&nbsp;"</FONT><FONT SIZE=2><B>Proposed Amendments</B></FONT><FONT SIZE=2>") and counsel's understanding of the current published administrative practices of the Canada Revenue Agency in effect

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following is a summary of the material U.S.&nbsp;federal income tax consequences of the acquisition, ownership and disposition of
a Note by an initial purchaser thereof who is a U.S.&nbsp;Holder (as&nbsp;hereinafter defined) who purchases the Note for cash at its "issue price" (the&nbsp;first price at which a substantial
amount of the Notes is sold for cash, excluding sales to bond houses, brokers, or similar persons acting in the capacity of underwriters, placement agents or wholesalers) and who will hold the Note as
a "capital asset" within the meaning of Section&nbsp;1221 of the Internal Revenue Code of 1986, as amended (the&nbsp;"</FONT><FONT SIZE=2><B>Code</B></FONT><FONT SIZE=2>"). This summary is
intended for general information only and does not address all potentially relevant U.S.&nbsp;federal income tax&nbsp;matters. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
summary does not address the tax consequences to U.S.&nbsp;Holders subject to special provisions of the Code including, without limitation: banks; financial institutions;
tax-exempt organizations; insurance companies; regulated investment companies; holders subject to the alternative minimum tax; certain former citizens or residents of the United&nbsp;States; dealers
in securities or foreign currencies; traders in securities; holders holding Notes as part of a "hedge", "straddle", "conversion transaction" or other integrated transaction; and holders with a
"functional currency" other than the U.S.&nbsp;dollar. This summary also does not cover any state, local or non-U.S.&nbsp;tax consequences. This summary is based upon provisions of the Code,
Treasury Regulations promulgated thereunder, and rulings and judicial decisions in effect on the date hereof, all of which are subject to change (possibly with retroactive effect) and differing
interpretations, so as to result in U.S.&nbsp;federal income tax consequences different from those described herein. </FONT></P>

used herein, the term "</FONT><FONT SIZE=2><B>U.S.&nbsp;Holder</B></FONT><FONT SIZE=2>" means a beneficial owner of a Note that is (i)&nbsp;an individual who is a citizen or
resident of the United&nbsp;States as determined for U.S.&nbsp;federal income tax purposes, (ii)&nbsp;a corporation, or other entity treated as a corporation for U.S.&nbsp;federal income tax
purposes, created or organized under the laws of the United&nbsp;States or any political subdivision thereof, (iii)&nbsp;an estate the income of which is subject to U.S.&nbsp;federal income tax
without regard to its source, or (iv)&nbsp;a trust if a court within the United&nbsp;States is able to
exercise primary supervision over the administration of the trust and one or more United&nbsp;States persons have the authority to control all substantial decisions of the trust or if the trust has

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In certain circumstances we may be obligated to pay amounts in excess of stated interest or principal on the Notes (see, for example,
"</FONT><FONT SIZE=2><I>Description of Debt Securities</I></FONT><FONT SIZE=2>&nbsp;&#151;&nbsp;</FONT><FONT SIZE=2><I>Additional Amounts</I></FONT><FONT SIZE=2>" in the
accompanying Prospectus) and "Description of the Notes&nbsp;&#151;&nbsp;Repurchase Upon Change of Control Triggering Event" herein. Under the applicable U.S.&nbsp;Treasury
regulations, such excess amounts should not cause the Notes to be subject to special rules applicable to contingent payment debt instruments if, based on all the facts and circumstances as of the date
on which the Notes are issued, there is only a remote likelihood that any contingencies causing the payment of such excess amounts will occur, or if such excess amounts, in the aggregate, are
considered incidental. We believe that the possibility of paying excess amounts is remote and/or that such amounts are incidental. Accordingly, we do not intend to treat the Notes as contingent
payment debt instruments. Our position will be binding on a holder unless such holder timely and explicitly discloses its contrary position in the manner required by applicable U.S.&nbsp;Treasury
regulations. Our position, however, is not binding on the IRS. If the IRS successfully challenges this position, the timing and amount of income included and the character of the income recognized
with respect to the Notes may be materially and adversely different from the consequences discussed herein. Holders should consult their own tax advisors regarding this issue. The remainder of this
discussion assumes that the Notes will not be treated as contingent payment debt instruments. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> Payments of Interest  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest on the Notes will generally be taxable to a U.S.&nbsp;Holder as ordinary income at the time received or accrued, in
accordance with such holder's method of accounting for U.S.&nbsp;federal income tax purposes. Such interest will constitute income from sources outside the United&nbsp;States for
U.S.&nbsp;foreign tax credit limitation purposes. The rules governing U.S.&nbsp;foreign tax credits are complex.
Prospective purchasers of Notes should consult their tax advisors regarding the availability of U.S.&nbsp;foreign tax credits in their particular circumstances. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> Sale, Exchange, Retirement or Redemption of Notes  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon the sale, exchange, retirement, redemption or other taxable disposition of a Note, a U.S.&nbsp;Holder generally will recognize
gain or loss equal to the difference between the amount realized on such sale, exchange, retirement or redemption (other than amounts received that are attributable to accrued and unpaid interest,
which amounts will be taxable as ordinary income to the extent not previously included in income) and such U.S.&nbsp;Holder's adjusted tax basis in the Note, which generally is its cost. Such gain
or loss generally will constitute capital gain or loss and will be long-term capital gain or loss if the Note was held by such U.S.&nbsp;Holder for more than one year. Long-term capital gain of
non-corporate U.S.&nbsp;Holders, including individuals, is generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to&nbsp;limitations. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Gain
or loss recognized by a U.S.&nbsp;Holder generally will be treated as U.S.&nbsp;source income or loss for foreign tax credit purposes. Prospective investors should consult their
own tax advisors as to the foreign tax credit implications of such sale, exchange or other disposition of a&nbsp;Note. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> Additional Tax on Investment Income  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain U.S.&nbsp;Holders who are individuals, estates or trusts and whose income exceeds certain thresholds generally will be
required to pay an additional 3.8&nbsp;percent tax on all or a portion of their "net investment income," which includes, among other things, interest income and capital gains from the sale or other
disposition of a Note, subject to certain limitations and exceptions. U.S.&nbsp;Holders should consult their own tax advisors regarding the application of this additional surtax to their investment
in the&nbsp;Notes. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2><B><I> Information Reporting and Backup Withholding  </I></B></FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In general, payments of interest and principal on and the proceeds from sales of Notes held by a U.S.&nbsp;Holder will be required to
be reported to the IRS unless the U.S.&nbsp;Holder is a corporation or other exempt recipient and, when required, demonstrates this fact. In addition, a U.S.&nbsp;Holder that is not an exempt
recipient may be subject to backup withholding of U.S.&nbsp;federal income tax on such payments unless it provides a taxpayer identification number and otherwise complies with applicable
certification requirements. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S.&nbsp;Holder generally will be </FONT></P>

connection with this offering, the Representatives may purchase and sell Notes in the open market. These transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of the Notes in excess of the principal amount of the Notes to be purchased by the underwriters in this offering, which creates a
syndicate short position. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of certain bids or purchases of the Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while this offering is
in&nbsp;progress. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
underwriters may also impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the Representatives, in covering
syndicate short positions or making stabilizing purchases, repurchases Notes originally sold by that syndicate member. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of these activities, the market price of the Notes offered under this Prospectus Supplement may be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at any time without notice. The underwriters may carry out these transactions in the over-the-counter market
or&nbsp;otherwise. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity
securities (or&nbsp;related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities
activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit
exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of
either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such short positions could adversely affect future
trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such
securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. </FONT></P>

Securities that are not within the options and parameters set forth in this Prospectus. You should read this Prospectus and any applicable Prospectus Supplement before you invest in

which additional series of First Preferred Shares, Warrants, Subscription Receipts or debt securities may be sold and purchasers may not be able to resell such Securities purchased under this
Prospectus. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer
regulation. Investing in the Securities involves risks. See "</B></FONT><FONT SIZE=2><B><I>Risk Factors</I></B></FONT><FONT SIZE=2><B>" in this Prospectus and in any applicable Prospectus

may sell the Securities to or through underwriters or dealers purchasing as principals, directly to one or more purchasers pursuant to applicable statutory exemptions or through agents. See
"</FONT><FONT SIZE=2><I>Plan of Distribution</I></FONT><FONT SIZE=2>". The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent engaged
in connection with the offering and sale of the Securities, and will set forth the terms of the offering of such Securities, including the method of distribution, the proceeds to us and any fees,
discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of offering of such Securities. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>Unless
otherwise specified in the applicable Prospectus Supplement, each series or issue of Securities (other than Common Shares) will be a new issue of Securities with no established trading market.
The Securities may be sold from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a non-fixed price basis the Securities may be offered at
market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers, in which case the compensation payable to an
underwriter, dealer or agent in connection with any such sale will be the amount, if any, by which the aggregate price paid for the Securities by the purchasers exceeds the gross proceeds paid by the
underwriter, dealer or agent to us and the price at which the Securities will be offered and sold may vary as between purchasers during the distribution period. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>In
connection with any offering of Securities, the underwriters may over allot or effect transactions which stabilize, maintain or otherwise affect the market price of the Securities at a level above
that which otherwise might prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any time. See "</FONT><FONT SIZE=2><I>Plan of

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
evaluate our performance using a variety of measures. Earnings coverage discussed above is not defined under IFRS and therefore, should not be considered in isolation or as an
alternative to, or more meaningful than, net earnings as determined in accordance with IFRS as an indicator of our financial performance or liquidity. This measure is not necessarily comparable to a
similarly titled measure of another company. Net earnings (loss) has been calculated on a consistent basis for the twelve month period ended December&nbsp;31, 2011 and the twelve month period ended
September&nbsp;30,&nbsp;2012. </FONT></P>

-$254&nbsp;million, respectively, which is 2.7&nbsp;times and -1.1&nbsp;times, respectively, TransAlta's interest requirements, as adjusted as described above, for such

September&nbsp;30, 2012, in order to achieve an earnings coverage ratio of one-to-one for such&nbsp;period. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Each
Common Share of the Corporation entitles the holder thereof to one vote for each Common Share held at all meetings of shareholders of the Corporation, except meetings at which only
holders of another specified class or series of shares are entitled to vote, to receive dividends if, as and when declared by the board of directors, subject to prior satisfaction of preferential
dividends applicable to any First Preferred Shares, and to participate rateably in any distribution of the assets of the Corporation upon a liquidation, dissolution or winding up, subject to prior
rights and privileges attaching to the First Preferred Shares. The Common Shares are not convertible and are not entitled to any pre-emptive rights. The Common Shares are not entitled to cumulative
voting. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

First Preferred Shares of all series rank senior to all other shares of TransAlta with respect to priority in payment of dividends and with respect to distribution of assets in the

subscription price thereof as and when declared by the board of directors at the rate established by the board of directors at the time of issue of shares of a series. No dividends may be declared or
paid on any other shares of TransAlta unless all cumulative dividends accrued upon all outstanding First Preferred Shares have been paid or declared and set apart. In the event of the liquidation,
dissolution or winding up of the Corporation, or a reduction of stated capital, no sum shall be paid or assets distributed to holders of other shares of the Corporation until the holders of First
Preferred Shares shall have been paid the subscription price of the shares, plus a sum equal to the premium payable on a redemption, plus a sum equal to the arrears of dividends accumulated on the
First Preferred Shares to the date of such liquidation, dissolution, winding up, or reduction of stated capital, as applicable. After payment of such amount, the holders of First Preferred Shares

under one or more subscription receipt agreements. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
Subscription Receipt is a security of the Corporation that will entitle the holder to receive one Common Share upon the completion of a transaction, typically an acquisition by us of
the assets or securities of another entity. After the offering of Subscription Receipts, the subscription proceeds for the Subscription Receipts are held in escrow by the designated escrow agent,
pending the completion of the transaction. Holders of Subscription Receipts will not have any rights of shareholders of the Corporation. Holders of Subscription Receipts are only entitled to receive
Common Shares upon the surrender of their Subscription Receipts to the escrow agent or to a return of the subscription price for the Subscription Receipts together with any payments in lieu of
interest or other income earned on the subscription proceeds. </FONT></P>

Whenever there are references to particular provisions of the Indenture, those provisions are qualified in their entirety by reference to the Indenture. References in parentheses are to section

interests in a Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary therefor or its nominee (with respect to

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We may sell the Securities to or through underwriters or dealers and also may sell the Securities directly to purchasers pursuant to
applicable statutory exemptions or through&nbsp;agents. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
distribution of the Securities of any series may be effected from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a
non-fixed price basis the Securities may be offered at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers,
in which case the compensation payable to an underwriter, dealer or agent in connection with any such sale will be the amount, if any, by which the aggregate price paid for the Securities by the
purchasers exceeds the gross proceeds paid by the underwriter, dealer or agent to us and the price at which the Securities will be offered and sold may vary as between purchasers during the
distribution period. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
connection with the sale of the Securities, underwriters may receive compensation from TransAlta or from purchasers of the Securities for whom they may act as agents in the form of
concessions or commissions. Underwriters, dealers and agents that participate in the distribution of the Securities may be deemed to be underwriters and any commissions received by them from TransAlta
and any profit on the resale of the Securities by them may be deemed to be underwriting commissions. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Prospectus Supplement relating to each series of the Securities will also set forth the terms of the offering of the Securities, including to the extent applicable, the initial
offering price, the proceeds to the Corporation, the underwriting concessions or commissions, and any other discounts or concessions to be allowed or re-allowed to dealers. Underwriters with respect
to each series sold to or through underwriters will be named in the Prospectus Supplement relating to such&nbsp;series. </FONT></P>

<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
connection with any offering of Securities, the underwriters may over allot or effect transactions which stabilize, maintain or otherwise affect the market price of the Securities at
a level above that which otherwise might prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any&nbsp;time. </FONT></P>


<P style="font-family:times;text-align:justify"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
agreements which may be entered into by TransAlta, underwriters, dealers and agents who participate in the distribution of the Securities may be entitled to indemnification by the
Corporation against certain liabilities, including liabilities under the securities legislation of each of the provinces of Canada or under the U.S.&nbsp;Securities&nbsp;Act. </FONT></P>
