                STATEMENTS REGARDING FORWARD-LOOKING INFORMATION

    The Securities and Exchange Commission encourages companies to disclose
forward-looking information so that investors can better understand a company's
future prospects and make informed investment decisions. This prospectus
contains such 'forward-looking statements' within the meaning of the Private
Securities Litigation Reform Act of 1995. These statements may be made directly
in this prospectus referring to us and they may also be made a part of this
prospectus by reference to other documents filed with the Securities and
Exchange Commission by us, America Online or Time Warner, which is known as
'incorporation by reference.'

    Words such as 'anticipate', 'estimate', 'expects', 'projects', 'intends',
'plans', 'believes' and words and terms of similar substance used in connection
with any discussion of future operating or financial performance identify
forward-looking statements. All forward-looking statements are management's
present expectations of future events and are subject to a number of factors and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements. Actual results may vary materially
from those described in the forward-looking statements due to a variety of
factors. Investors are cautioned not to place undue reliance on the
forward-looking statements, which speak only as of the date of this prospectus
or the date of the document incorporated by reference in this prospectus. None
of us, America Online, Time Warner, Time Warner Companies, Inc. and Turner
Broadcasting System, Inc. is under any obligation, and each expressly disclaims
any obligation, to update or alter any forward-looking statements, whether as a
result of new information, future events or otherwise.

    AOL Time Warner operates in highly competitive, consumer driven and rapidly
changing Internet, media and entertainment businesses that are dependent on
government regulation and economic, political and social conditions in the
countries in which they operate, consumer demand for their products and
services, technological developments and (particularly in view of technological
changes) protection of their intellectual property rights. AOL Time Warner's
actual results could differ materially from management's expectations because of
changes in such factors and factors affecting the integration of the businesses
of America Online and Time Warner.

    For additional information about factors that could cause actual results to
differ materially from those described in the forward-looking statements, please

                       RATIO OF EARNINGS TO FIXED CHARGES

    The ratio of earnings to fixed charges and the ratio of earnings to combined
fixed charges and preferred dividends for each of AOL Time Warner, America
Online, Time Warner, TWC and TBS are set forth below for the periods indicated.
For periods in which earnings before fixed charges were insufficient to cover
fixed charges (or combined fixed charges and preferred dividends), the dollar
amount of coverage deficiency (in millions), instead of the ratio, is disclosed.

    In addition to the historical ratios (or coverage deficiencies), pro forma
ratios of earnings to fixed charges and pro forma ratios of earnings to combined
fixed charges and preferred dividends are presented that give effect to the
merger of America Online and Time Warner as if it occurred at the beginning of
each period. Because America Online and Time Warner have different fiscal years,
and the combined company has adopted the calendar year-end of Time Warner, pro
forma ratios for AOL Time Warner are presented on two different bases as
follows: (1) a June 30 fiscal year basis, which is consistent with America
Online's historical fiscal year-end, and (2) a December 31 calendar year basis,
which is consistent with Time Warner's historical fiscal year-end and that of
AOL Time Warner going forward. Management believes that it is meaningful to
present pro forma financial information based on the calendar year-end of the
combined company to facilitate an analysis of the pro forma effects of the
merger.

    Further, as a result of the merger of America Online and Time Warner, the
pro forma ratios of Time Warner, TWC and TBS have each been adjusted to reflect
an allocable portion of AOL Time Warner's new basis of accounting on a pushdown
basis. The historical ratios are reflected at each company's historical cost
basis of accounting.

    The pro forma ratios have been derived from, and should be read in
conjunction with, the pro forma consolidated condensed financial statements
including the notes thereto, of AOL Time Warner. Those pro forma consolidated
condensed financial statements are included in AOL Time Warner's Current Report
on Form 8-K/A dated January 11, 2001, which is incorporated herein by reference.

    For purposes of computing the ratio of earnings to fixed charges and the
ratio of earnings to combined fixed charges and preferred stock dividends,
earnings were calculated by adding:

        (i) pretax income,

        (ii) interest expense, including previously capitalized interest
    amortized to expense and the portion of rents representative of an interest
    factor for AOL Time Warner, America Online, Time Warner, TWC, TBS and their
    respective majority-owned subsidiaries,

        (iii) AOL Time Warner's, America Online's, Time Warner's, TWC's, and
    TBS's respective proportionate share of the items included in (ii) above for
    their 50%-owned companies,

        (iv) preferred stock dividend requirements of majority-owned companies,

        (v) minority interest in the income of majority-owned subsidiaries that
    have fixed charges, and

        (vi) the amount of undistributed losses of each of AOL Time Warner's,
    America Online's, Time Warner's, TWC's and TBS's less than 50%-owned
    companies.

    Fixed charges consist of:

        (i) interest expense, including interest capitalized and the portion of
    rents representative of an interest factor for AOL Time Warner, America
    Online, Time Warner, TWC, TBS and their respective majority-owned
    subsidiaries,

        (ii) AOL Time Warner's, America Online's, Time Warner's, TWC's, and
    TBS's respective proportionate share of such items for their 50%-owned
    companies, and

        (iii) preferred stock dividend requirements of majority-owned
    subsidiaries.

    Combined fixed charges and preferred stock dividends include the fixed
charges mentioned above and the amount of pretax income necessary to cover any
preferred stock dividend requirements of the registrant.

                                       10





    Earnings as defined include significant non-cash charges for depreciation
and amortization primarily relating to the amortization of intangible assets
recognized in business combinations accounted for by the purchase method. On a
pro forma basis, based on a preliminary allocation of the purchase price paid in
the merger of America Online and Time Warner, earnings have been reduced by
annual non-cash amortization charges of $6.929 billion for both AOL Time Warner
and Time Warner, $5.580 billion for TWC and $1.687 billion for TBS.

     January 11, 2001 in connection with the consummation of the merger of
     America Online and Time Warner with subsidiaries of AOL Time Warner.

(b) Time Warner became the parent of TWC and TBS on October 10, 1996, upon the
    merger of TWC and TBS with separate subsidiaries of Time Warner (the 'TBS
    Merger'). The historical ratios of TBS for all periods after the TBS Merger
    have been adjusted to reflect Time Warner's basis of accounting. The
    historical ratios of TBS for all periods before the TBS Merger are reflected

                                USE OF PROCEEDS

    We will use the net proceeds we receive from the sale of the securities
offered by this prospectus and the accompanying prospectus supplement for
general corporate purposes, unless we specify otherwise in the applicable
prospectus supplement. General corporate purposes may include additions to
working capital, capital expenditures, repayment of debt, the financing of
possible acquisitions and investments or stock repurchases.

             DESCRIPTION OF THE DEBT SECURITIES AND THE GUARANTEES

GENERAL

    The following description of the terms of the debt securities sets forth
certain general terms and provisions of the debt securities to which any
prospectus supplement may relate. The particular terms of any debt securities
and the extent, if any, to which such general provisions will not apply to such
debt securities will be described in the prospectus supplement relating to such
debt securities.

    The debt securities will be issued from time to time in series under an
indenture among us, America Online, Time Warner, TWC, TBS and The Chase
Manhattan Bank, as Trustee. The statements set forth below are brief summaries
of certain provisions contained in the indenture, which summaries do not purport
to be complete and are qualified in their entirety by reference to the
indenture, a form of which is an Exhibit to the registration statement of which
this prospectus is a part. If we issue subordinated debt, it may be issued
either under the same indenture as for senior debt or another indenture in
substantially the same form. Wherever defined terms are used but not defined
herein, such terms shall have the meanings assigned to them in the indenture, it
being intended that such defined terms shall be incorporated herein by
reference.

    The indenture does not limit the amount of debt securities which may be
issued thereunder and debt securities may be issued thereunder up to the
aggregate principal amount which may be authorized from time to time by us. Any
such limit applicable to a particular series will be specified in the prospectus
supplement relating to that series.

    Reference is made to the prospectus supplement for the following terms of
each series of debt securities in respect to which this prospectus is being
delivered:

     the designation, issue date, currency or currency unit of payment if other
     than United States dollars and authorized denominations of such debt
     securities, if other than US$1,000 and integral multiples;

     the aggregate principal amount offered and any limit on any future issues
     of additional debt of the same series;

                                       12





     the date or dates on which such debt securities will mature (which may be
     fixed or extendible);

     the rate or rates (or manner of calculation thereof), if any, per annum at
     which such debt securities will bear interest;

     the dates, if any, on which such interest will be payable;

     the terms of any mandatory or optional redemption (including any sinking,
     purchase or analogous fund) and any purchase at the option of Holders
     (including whether any such purchase may be paid in cash, common stock or
     other securities or property);

     the terms of any mandatory or optional conversion or exchange provisions;

     whether such debt securities are to be issued in the form of Global
     Securities and, if so, the identity of the Depository with respect to such
     Global Securities;

     if the debt securities are to be subordinated in right of payment to any
     other securities, the terms of subordination; and

     any other specific terms.

    Unless otherwise set forth in the prospectus supplement, interest on
outstanding debt securities will be paid to Holders of record on the date, which
is 15 days prior to the date such interest is to be paid, or if not a business
day, the next preceding business day. Unless otherwise specified in the
prospectus supplement, debt securities will be issued in fully registered form
only. Unless otherwise specified in the prospectus supplement, the principal
amount of the debt securities will be payable at the corporate trust office of
the Trustee in New York, New York. The debt securities may be presented for
transfer or exchange at such office unless otherwise specified in the prospectus
supplement, subject to the limitations provided in the indenture, without any
service charge, but we may require payment of a sum sufficient to cover any tax
or other governmental charges payable in connection therewith.

GUARANTEES


    Under the Guarantees, each of America Online and Time Warner, as primary
obligor and not merely as surety, will fully, irrevocably and unconditionally
guarantee to each Holder of debt securities and to the Trustee and its
successors and assigns, (1) the full and punctual payment of principal of and
interest on the debt securities when due, whether at maturity, by acceleration,
by redemption or otherwise, and all other monetary obligations of ours under the
indenture (including obligations to the Trustee) and the debt securities and
(2) the full and punctual performance within applicable grace periods of all
other obligations of ours under the indenture and the debt securities. Such
Guarantees will constitute guarantees of payment, performance and compliance and
not merely of collection. The obligations of each of America Online and Time
Warner under the indenture will be unconditional irrespective of the absence or
existence of any action to enforce the same, the recovery of any judgment
against us or each other or any waiver or amendment of the provisions of the
indenture or the debt securities to the extent that any such action or similar
action would otherwise constitute a legal or equitable discharge or defense of a
guarantor (except that each such waiver or amendment shall be effective in
accordance with its terms). The obligations of America Online and Time Warner to
make any payments may be satisfied by causing us to make such payments. Each of
America Online and Time Warner further agrees to waive presentment to, demand of
payment from and protest to us and also waives diligence, notice of acceptance
of its Guarantee, presentment, demand for payment, notice of protest for non-
payment, filing a claim if we complete a merger or declare bankruptcy and any
right to require a proceeding first against us. These obligations shall be
unaffected by any failure or policy of the Trustee to exercise any right under
the indenture or under any series of security. If any Holder of any debt
security or the Trustee is required by a court or otherwise to return to us,
America Online or Time Warner, or any custodian, trustee, liquidator or other
similar official acting in relation to any of us, America Online or Time Warner,
any amount paid by any of them to the Trustee or such Holder, the Guarantee of
America Online and the Guarantee of Time Warner, to


                                       13






the extent theretofore discharged, shall be reinstated in full force and effect.
Further, America Online and Time Warner agree to pay any and all reasonable
costs and expenses (including reasonable attorneys' fees) incurred by the
Trustee or any Holder of debt securities in enforcing any of their respective
rights under the Guarantees. The indenture provides that each of the Guarantees
of America Online and Time Warner is limited to the maximum amount that can be
guaranteed by America Online or Time Warner, respectively, without rendering the
relevant Guarantee voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally.


    Additionally, TWC and TBS will fully, irrevocably and unconditionally
guarantee Time Warner's guarantee of the debt securities under substantially the
same terms as the guarantees of America Online and Time Warner of our
indebtedness.

RANKING


    The debt securities may be either senior or subordinated in right of payment
to other securities. If subordinated debt securities are offered, the terms of
subordination will be set forth in the related prospectus supplement. The
Guarantees of the senior debt securities will be senior obligations of America
Online, Time Warner, TWC and TBS, as applicable, and will be direct unsecured
obligations of America Online, Time Warner, TWC and TBS, respectively, ranking
equally with all other unsecured and unsubordinated obligations of America
Online, Time Warner, TWC and TBS, respectively. The Guarantees of the
subordinated debt securities will be subordinated obligations of America Online,
Time Warner, TWC and TBS, as applicable and will be direct and unsecured
obligations of America Online, Time Warner, TWC and TBS, respectively, ranking
equally with all other unsecured and subordinated obligations of America Online,
Time Warner, TWC and TBS, respectively. Each of our company, Time Warner, TWC
and TBS is a holding company and the debt securities and the Guarantees will be
effectively subordinated to all existing and future liabilities, including
indebtedness, of the subsidiaries of our company, Time Warner, TWC and TBS,
respectively.


CERTAIN COVENANTS

    Limitation on Liens. The indenture provides that neither we nor any Material
Subsidiary of ours shall incur, create, issue, assume, guarantee or otherwise
become liable for any indebtedness for money borrowed that is secured by a lien
on any asset now owned or hereafter acquired by us or it unless we make or cause
to be made effective provisions whereby the debt securities will be secured by
such lien equally and ratably with (or prior to) all other indebtedness thereby
secured so long as any such indebtedness shall be secured. The foregoing
restriction does not apply to the following:

     liens existing as of the date of the indenture;

     liens created by Subsidiaries of ours to secure indebtedness of such
     Subsidiaries to us or to one or more other Subsidiaries of ours;

     third-party investors in connection with the financing of such motion
     pictures, video and television programming, sound recordings or books in
     the ordinary course of business and the granting to us or any of our
     Subsidiaries of rights to distribute such motion pictures, video and
     television programming, sound recordings or books; provided, however, that
     no such lien shall attach to any asset or right of ours or our Subsidiaries
     (other than (1) the motion pictures, video and television programming,
     sound recordings, books or rights which were sold, transferred to or
     financed by the tax shelter group or third-party investors in question or
     the proceeds arising therefrom and (2) the stock or equity interests of a

     is not a Subsidiary of ours;


     liens on Works which either (1) existed in such Works before the time of
     their acquisition and were not created in anticipation thereof, or
     (2) were created solely for the purpose of securing obligations to
     financiers, producers, distributors, exhibitors, completion guarantors,
     inventors, copyright holders, financial institutions or other participants
     incurred in the ordinary course of business in connection with the
     acquisition, financing, production, completion, distribution or exhibition
     of Works;

     any lien on the office building and hotel complex located in Atlanta,
     Georgia known as the CNN Center Complex, including the parking decks for
     such complex (to the extent such parking decks are owned or leased by us or

     and the products, revenues and proceeds therefrom created as part of any
     mortgage financing or sale-leaseback of the CNN Center Complex;

     liens on satellite transponders and all property rights therein and the
     products, revenues and proceeds therefrom which secure obligations incurred

     satellite transponders or the refinancing of any such obligations;

     restrictions on the Atlanta National League Baseball Club, Inc., Atlanta
     Hawks, Ltd and the Atlanta Hockey Club, Inc. and their respective assets
     imposed by Major League Baseball or the Commissioner of Baseball, the
     National Basketball Association and the National Hockey League,
     respectively, including, without limitation, restrictions on the
     transferability of our or any of our Subsidiaries' interests therein;

     liens on capital leases entered into after the date of the indenture
     provided that such liens extend only to the property or assets that are the
     subject of such capital leases;

     liens resulting from progress payments or partial payments under United
     States government contracts or subcontracts;

     any extensions, renewal or replacement of any lien referred to in the
     foregoing clauses or of any indebtedness secured thereby; provided,
     however, that the principal amount of indebtedness secured thereby shall
     not exceed the principal amount of indebtedness so secured at the time of
     such extension, renewal or replacement, or at the time the lien was issued,
     created or assumed or otherwise permitted, and that such extension, renewal
     or replacement lien shall be limited to all or part of substantially the
     same property which secured the lien extended, renewed or replaced (plus
     improvements on such property); and

     other liens arising in connection with our indebtedness and our
     Subsidiaries' indebtedness in an aggregate principal amount for us and our
     Subsidiaries not exceeding at the time such lien is issued, created or
     assumed the greater of (A) 15% of the Consolidated Net Worth of our company
     and (B) $500 million.

                                       15

assets substantially as an entirety to any Person, unless:

        or into which our company is merged or the Person which acquires by
        conveyance or transfer the properties and assets of our company
        substantially as an entirety shall be organized and existing under the
        laws of the United States of America or any State or the District of
        Columbia, and shall expressly assume, by supplemental indenture,
        executed and delivered to the Trustee, in form satisfactory to the
        Trustee, the due and punctual payment of the principal of (and premium,
        if any) and interest on all the debt securities and the performance of
        every covenant of the indenture (as supplemented from time to time) on
        the part of our company to be performed or observed; (b) in the case of
        America Online, Time Warner, TWC or TBS, the Person formed by such
        consolidation or into which America Online, Time Warner, TWC or TBS is
        merged or the Person which acquires by conveyance or transfer the
        properties and assets of America Online, Time Warner, TWC or TBS
        substantially as an entirety shall be either (i) one of us, America
        Online, Time Warner, TWC or TBS or (ii) a Person organized and existing
        under the laws of the United States of America or any State or the
        District of Columbia, and in the case of clause (ii), shall expressly
        assume, by supplemental indenture, executed and delivered to the
        Trustee, in form satisfactory to the Trustee, the performance of every
        covenant of the indenture (as supplemented from time to time) on the
        part of America Online, Time Warner, TWC or TBS to be performed or
        observed;


    (2) immediately after giving effect to such transaction, no Event of
        Default, and no event which, after notice or lapse of time, or both,
        would become an Event of Default, shall have happened and be continuing;
        and

    (3) we have delivered to the Trustee an Officers' Certificate and an Opinion
        of Counsel each stating that such consolidation, merger, conveyance or
        transfer and such supplemental indenture comply with this Article and
        that all conditions precedent provided for relating to such transaction
        have been complied with.

    Upon any consolidation or merger, or any conveyance or transfer of the
properties and assets of our company, America Online, Time Warner, TWC or TBS
substantially as an entirety as set forth above, the successor Person formed by
such consolidation or into which our company, America Online, Time Warner, TWC
or TBS is merged or to which such conveyance or transfer is made shall succeed
to, and be substituted for, and may exercise every right and power of our
company, America Online, Time Warner, TWC or TBS, as the case may be, under the
indenture with the same effect as if such successor had been named as our
company, America Online, Time Warner, TWC or TBS, as the case may be, in the
indenture. In the event of any such conveyance or transfer, we, America Online,
Time Warner, TWC or TBS, as the case may be, as the predecessor shall be
discharged from all obligations and covenants under the indenture and the debt
securities and may be dissolved, wound up or liquidated at any time thereafter.

    Other than the restrictions in the indenture on liens described above, the
indenture and the debt securities do not contain any covenants or other
provisions designed to afford Holders of debt securities protection in the event
of a recapitalization or highly leveraged transaction involving our company.

    Any additional covenants of our company, America Online, Time Warner, TWC or
TBS pertaining to a series of debt securities will be set forth in a prospectus
supplement relating to such series of debt securities.

DEFEASANCE

    The indenture provides that we (and to the extent applicable, America
Online, Time Warner, TWC and TBS), at our option,

    (a) will be Discharged from any and all obligations in respect of any series
        of debt securities (except in each case for certain obligations to
        register the transfer or exchange of debt securities, replace stolen,
        lost or mutilated debt securities, maintain paying agencies and hold
        moneys for payment in trust) or

    (b) need not comply with the covenants described above under 'Certain
        Covenants' and any other restrictive covenants described in a prospectus
        supplement relating to such series of debt securities, and certain
        Events of Default (other than those arising out of the failure to pay
        interest or principal on the debt securities of a particular series and
        certain events of bankruptcy, insolvency and reorganization) will no
        longer constitute Events of Default with respect to such series of debt
        securities,

in each case if we deposit with the Trustee, in trust, money or the equivalent
in securities of the government which issued the currency in which the debt
securities are denominated or government agencies backed by the full faith and
credit of such government, or a combination thereof, which through the payment
of interest thereon and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay all the principal (including any
mandatory sinking

                                       17





fund payments) of, and interest on, such series on the dates such payments are
due in accordance with the terms of such series.

    To exercise any such option, we are required, among other things, to deliver
to the Trustee an opinion of counsel to the effect that

    (i) the deposit and related defeasance would not cause the Holders of such
        series to recognize income, gain or loss for Federal income tax purposes
        and, in the case of a Discharge pursuant to clause (a), accompanied by a
        ruling to such effect received from or published by the United States
        Internal Revenue Service and

   (ii) the creation of the defeasance trust will not violate the Investment
        Company Act of 1940, as amended.

    In addition, we are required to deliver to the Trustee an Officers'
Certificate stating that such deposit was not made by us with the intent of
preferring the Holders over other creditors of ours or with the intent of
defeating, hindering, delaying or defrauding creditors of our company or others.

EVENTS OF DEFAULT, NOTICE AND WAIVER

    The indenture provides that, if an Event of Default specified therein with
respect to any series of debt securities issued thereunder shall have happened
and be continuing, either the Trustee thereunder or the Holders of 25% in
aggregate principal amount of the outstanding debt securities of such series (or
25% in aggregate principal amount of all outstanding debt securities under the
indenture, in the case of certain Events of Default affecting all series of debt
securities under the indenture) may declare the principal of all the debt
securities of such series to be due and payable.

    Events of Default in respect of any series are defined in the indenture as
being:

     default for 30 days in payment of any interest installment with respect to
     such series;

     default in payment of principal of, or premium, if any, on, or any sinking
     fund or analogous obligation with respect to, debt securities of such
     series when due at their stated maturity, by declaration or acceleration,
     when called for redemption or otherwise;


     default for 90 days after written notice to us (or America Online, Time
     Warner, TWC or TBS, if applicable) by the Trustee thereunder or by Holders
     of 25% in aggregate principal amount of the outstanding debt securities of
     such series in the performance, or breach, of any covenant pertaining to
     debt securities of such series;



     certain events of bankruptcy, insolvency and reorganization with respect to
     us or any Material Subsidiary thereof which is organized under the laws of
     the United States or any political sub-division thereof or the entry of an
     order ordering the winding up or liquidation of our affairs; and


     any Guarantee ceasing to be, or asserted by any guarantor as not being, in
     full force and effect, enforceable according to its terms, except to the
     extent contemplated by the indenture.

    Any additions, deletions or other changes to the Events of Default which
will be applicable to a series of debt securities will be described in the
prospectus supplement relating to such series of debt securities.


    The indenture provides that the Trustee thereunder will, within 90 days
after the occurrence of a default with respect to the debt securities of any
series, give to the Holders of the debt securities of such series notice of all
uncured and unwaived defaults known to it; provided, however, that, except in
the case of default in the payment of principal of, premium, if any, or
interest, if any, on any of the debt securities of such series, the Trustee
thereunder will be protected in withholding such notice if it in good faith
determines that the withholding of such notice is in the interests of the
Holders of the debt securities of such series. The term 'default'


                                       18






for the purpose of this provision means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to debt
securities of such series.


    The indenture contains provisions entitling the Trustee, subject to the duty
of the Trustee during an Event of Default to act with the required standard of
care, to be indemnified by the Holders of the debt securities before proceeding
to exercise any right or power under the indenture at the request of Holders of
the debt securities.

    The indenture provides that the Holders of a majority in aggregate principal
amount of the outstanding debt securities of any series may direct the time,
method and place of conducting proceedings for remedies available to the Trustee
or exercising any trust or power conferred on the Trustee in respect of such
series, subject to certain conditions.


    In certain cases, the Holders of a majority in principal amount of the
outstanding debt securities of any series may waive, on behalf of the Holders of
all debt securities of such series, any past default or Event of Default with
respect to the debt securities of such series except, among other things, a
default not theretofore cured in payment of the principal of, or premium, if
any, or interest, if any, on any of the debt securities of such series or
payment of any sinking or purchase fund or analogous obligations with respect to
such debt securities.


    The indenture includes a covenant that we will file annually with the
Trustee a certificate of no default or specifying any default that exists.

MODIFICATION OF THE INDENTURE

    We and the Trustee may, without the consent of the Holders of the debt
securities, enter into indentures supplemental to the indenture for, among
others, one or more of the following purposes:

     (1) to evidence the succession of another Person to us, America Online,
         Time Warner, TWC or TBS and the assumption by such successor of our
         company's, America Online's, Time Warner's, TWC's or TBS's obligations
         under the indenture and the debt securities of any series or the
         Guarantees relating thereto;

     (2) to add to the covenants of our company, America Online, Time Warner,
         TWC or TBS, or to surrender any rights or powers of our company,
         America Online, Time Warner, TWC or TBS, for the benefit of the Holders
         of debt securities of any or all series;

     (3) to cure any ambiguity, or correct any inconsistency in the indenture or
         to make any other provisions with respect to matters or questions
         arising under this indenture;


     (4) to add to the indenture any provisions that may be expressly permitted
         by the Trust Indenture Act, or 'the Act', excluding the provisions
         referred to in Section 316(a)(2) of the Act as in effect at the date as
         of which this instrument was executed or any corresponding provision in
         any similar federal statute hereafter enacted;


     (5) to establish the form or terms of any series of debt securities;

     (6) to evidence and provide for the acceptance of any successor Trustee
         with respect to one or more series of debt securities or to facilitate
         the administration of the trusts thereunder by one or more trustees in
         accordance with the indenture;

     (7) to provide any additional Events of Default;

     (8) to provide for the issuance of debt securities in coupon or as fully
         registered form;

     (9) to provide for the terms and conditions of converting those debt
         securities that are convertible into common stock or another such
         similar security; and

    (10) to secure any series of debt securities pursuant to the indenture's
         limitation on liens.

    No supplemental indenture for the purpose identified in clauses (2), (3),
(5) or (7) above may be entered into if to do so would adversely affect the
rights of the Holders of debt securities of any series in any material respect.

                                       19





    The indenture contains provisions permitting us and the Trustee thereunder,
with the consent of the Holders of a majority in principal amount of the
outstanding debt securities of all series to be affected voting as a single
class, to execute supplemental indentures by adding any provisions to or
changing or eliminating any of the provisions of the indenture or modifying the
rights of the Holders of the debt securities of such series to be affected,
except that no such supplemental indenture may, without the consent of the
Holders of affected debt securities, among other things:

     change the fixed maturity of any debt securities, or

     reduce the principal amount thereof, or

     reduce the rate or extend the time of payment of interest thereon, or

     reduce the number of shares of any common stock or other securities to be
     delivered by us in respect of a conversion of any convertible debt
     securities, or

     amend or modify the terms of any of the Guarantees in a manner adverse to
     the Holders or reduce the aforesaid percentage of debt securities of any
     series the consent of the Holders of which is required for any such
     supplemental indenture.

THE TRUSTEE

    The Chase Manhattan Bank is the Trustee under the indenture. The Trustee is
a depository for funds and performs other services for, and transacts other
banking business with, us in the normal course of business.

GOVERNING LAW

    The indenture will be governed by, and construed in accordance with, the
laws of the State of New York.

GLOBAL SECURITIES

    We may issue debt securities through global securities. A global security is
a security, typically held by a depositary, that represents the beneficial
interests of a number of purchasers of the security. If we do issue global
securities, the following procedures will apply.

    We will deposit global securities with the depositary identified in the
prospectus supplement. After we issue a global security, the depositary will
credit on its book-entry registration and transfer system the respective
principal amounts of the debt securities represented by the global security to
the accounts of persons that have accounts with the depositary. These account
Holders are known as 'participants'. The underwriters or agents participating in
the distribution of the debt securities will designate the accounts to be
credited. Only a participant or a person that holds an interest through a
participant may be the beneficial owner of a global security. Ownership of
beneficial interests in the global security will be shown on, and the transfer
of that ownership will be effected only through, records maintained by the
depositary and its participants.

    We and the trustee will treat the depositary or its nominee as the sole
owner or Holder of the debt securities represented by a global security. Except
as set forth below, owners of beneficial interests in a global security will not
be entitled to have the debt securities represented by the global security
registered in their names. They also will not receive or be entitled to receive
physical delivery of the debt securities in definitive form and will not be
considered the owners or Holders of the debt securities.

    Principal, any premium and any interest payments on debt securities
represented by a global security registered in the name of a depositary or its
nominee will be made to the depositary or its nominee as the registered owner of
the global security. None of us, the trustee or any paying agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the global
security or the maintaining, supervising or reviewing any records relating to
the beneficial ownership interests.

                                       20





    We expect that the depositary, upon receipt of any payments, will
immediately credit participants' accounts with payments in amounts proportionate
to their respective beneficial interests in the principal amount of the global
security as shown on the depositary's records. We also expect that payments by
participants to owners of beneficial interests in the global security will be
governed by standing instructions and customary practices, as is the case with
the securities held for the accounts of customers registered in 'street names',
and will be the responsibility of the participants.

    If the depositary is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by us within ninety days,
we will issue registered securities in exchange for the global security. In
addition, we may at any time in our sole discretion determine not to have any of
the debt securities of a series represented by global securities. In that event,
we will issue debt securities of that series in definitive form in exchange for
the global securities.

                        DESCRIPTION OF THE CAPITAL STOCK

    The following description of the terms of the common stock and the preferred

also summarizes relevant provisions of the Delaware General Corporation Law,

                                       21





    If we offer shares of a new series of series common stock, the prospectus
supplement will specify the designation and number of shares of that series, and

     shares of such series.

    The powers, preferences and relative, participating, optional and other
special rights of each series of preferred stock, and the qualifications,
limitations or restrictions thereof, if any, may differ from those of any and

vote per share.

    Dividends. Holders of our common stock are entitled to receive dividends or
other distributions when and if declared by our board of directors. The right of

                                       22





EXISTING SERIES COMMON STOCK

SERIES LMC COMMON STOCK

    LMC Formula Number. Shares of our series LMC common stock are attributed a
'formula number' that is used to calculate the dividend, voting, conversion and
liquidation rights for each share of our series LMC common stock. We refer to
this formula number as the 'LMC formula number'. The LMC formula number is
initially set at 1.00, and it is subject to adjustment for stock splits, reverse
stock splits, stock dividends and other similar corporate events affecting our
common stock.

    Voting Rights. Each outstanding share of our series LMC common stock is
entitled to a number of votes that is equal to the product of the number of
votes per share that may be cast by holders of our common stock multiplied by
the LMC formula number in effect at the time of the vote.

    Holders of our series LMC common stock are entitled to vote on all matters
on which holders of our common stock are entitled to vote. Holders of our series
LMC common stock vote together as one group with holders of our common stock. A
vote of at least two-thirds of the voting power of all shares of our series LMC
common stock that are outstanding is necessary in order to amend, alter or
repeal any of the provisions of our restated certificate of incorporation,
including the certificate of designations relating to our series LMC common
stock, to:

     amend, alter or repeal any of the powers, preferences or rights of our
     series LMC common stock or series LMCN-V common stock; or

     adversely affect the voting powers, designations, preferences and relative,
     participating, optional or other special rights, and qualifications,
     limitations or restrictions, of our series LMC common stock or series
     LMCN-V common stock.

In addition, the affirmative vote of holders of shares of our series LMC common
stock representing 100% of the aggregate voting power of the outstanding shares
of our series LMC common stock is required to amend, alter or repeal the
provisions of the certificate of designations that prohibit us from, at our
option, redeeming the shares of our series LMC common stock.

    The vote of the holders of shares of our series LMC common stock is not
required for us to:

     create any indebtedness;

     authorize or issue any class of capital stock that is senior to, or on a
     parity with, our series LMC common stock with respect to the payment of
     dividends or any other distribution of assets;

     approve any amendment to our restated certificate of incorporation that
     would increase or decrease the aggregate number of authorized shares of our
     series common stock or our common stock; or

     authorize any increase or decrease in the number of shares constituting our
     series LMC common stock.

    Cash Dividends. Holders of our series LMC common stock are entitled to
receive cash dividends when and if declared by our board of directors, but only
to the extent that regularly scheduled cash dividends are declared and paid on
our common stock. When declared, cash dividends on each share of our series LMC
common stock will equal the product of:

     the amount of the regularly scheduled cash dividend to be paid on one share
     of our common stock; multiplied by

     the LMC formula number in effect on the dividend payment date.

    Distributions. If we distribute to the holders of our common stock any
assets or property, in each case not including a distribution upon the
liquidation of our company, a regularly scheduled cash dividend or a common
stock dividend that results in an adjustment of the LMC formula number, then we
must at the same time distribute the same assets or property pro rata to the
holders of our series LMC common stock in an amount equal to the amount that the
holders of

                                       23





our series LMC common stock would have been entitled to receive had they
converted their shares of our series LMC common stock into shares of our common
stock immediately prior to the record date for the distribution.

    Conversion Rights. Holders of our series LMC common stock have the right to
convert each of their shares, at any time, into:

     a number of shares of our common stock equal to the LMC formula number in
     effect on the conversion date; or

     one share of our series LMCN-V common stock.

    Each holder of our series LMC common stock may convert shares of our series
LMC common stock into shares of our common stock or our series LMCN-V common
stock only to the extent that the ownership by the converting holder of shares
of our common stock or our series LMCN-V common stock upon conversion would not
violate the federal communications laws.

    Conversion Rate Adjustment. If we consolidate or merge with another entity
such that we are not the surviving entity or the transaction results in a change
in our common stock, or if we sell all or substantially all of our property and
assets to another entity, each share of our series LMC common stock is
convertible into the number of shares of capital stock or other property
received by the holder of a number of shares of our common stock into which the
shares of our series LMC common stock could have been converted immediately
before the transaction.

    Liquidation Rights. In the event of the liquidation of our company, the
holders of our series LMC common stock are entitled to receive, at the same time
as any distribution to holders of our common stock, an aggregate amount per
share equal to the product of:

     the aggregate amount to be distributed per share to holders of our common
     stock; and

     the LMC formula number in effect on the date of the distribution.

    Transfer Restriction. Holders of our series LMC common stock are subject to
a transfer restriction that prevents these holders, without obtaining prior
consent from us, from transferring their shares of our series LMC common stock
to any person other than a 'permitted transferee'. The term 'permitted
transferee' means:

     Liberty Media Corporation, which is commonly referred to as 'LMC', and any
     affiliate that is controlled by LMC; or

     Tele-Communications Inc. and any affiliate that is controlled by
     Tele-Communications, so long as Tele-Communications is an affiliate of LMC.

In addition, the transfer restriction provides that any permitted transferee
must agree to be subject to the transfer restriction for subsequent transfers.

    The transfer restriction applicable to our series LMC common stock does not
prevent any holder of our series LMC common stock from:

     entering into an arrangement providing for the prompt conversion of the
     shares of our series LMC common stock into shares of our common stock and
     the immediate sale or transfer of our common stock received upon the
     conversion of shares of our series LMC common stock; or

     pledging shares of our series LMC common stock, so long as the terms of the
     pledge provide that, in the event of a foreclosure on the shares of our
     series LMC common stock, the foreclosing party delivers the forfeited
     series LMC common stock to us for conversion into our common stock.

SERIES LMCN-V COMMON STOCK

    LMCN-V Formula Number. Shares of our series LMCN-V common stock are
attributed a formula number that is used to calculate the dividend, voting,
conversion and liquidation rights for each share of our series LMCN-V common
stock. We refer to this formula number as the 'LMCN-V formula number'. The
LMCN-V formula number is initially set at 1.00, and it is

                                       24





subject to adjustment for stock splits, reverse stock splits, stock dividends
and other similar corporate events affecting our common stock.

    Voting Rights. Holders of our series LMCN-V common stock are entitled to
vote together as one group with holders of our common stock in the election of
directors of our company, and they have the right to cast a number of votes per
share that is equal to:

     the product of the number of votes per share that may be cast by holders of
     our common stock multiplied by the LMCN-V formula number in effect at the
     time of the vote; divided by

     100.

    A vote of at least two-thirds of the voting power of all shares of our
series LMCN-V common stock that are outstanding is necessary in order to amend,
alter or repeal any of the provisions of our restated certificate of
incorporation, including the certificate of designations relating to our series
LMCN-V common stock, to:

     amend, alter or repeal any of the powers, preferences or rights of our
     series LMCN-V common stock or series LMC common stock; or

     adversely affect the voting powers, designations, preferences and relative,
     participating, optional or other special rights, and qualifications,
     limitations or restrictions, of our series LMCN-V common stock or series
     LMC common stock.

In addition, the affirmative vote of holders of shares of our series LMCN-V
common stock representing 100% of the aggregate voting power of the outstanding
shares of our series LMCN-V common stock is required to amend, alter or repeal
the provisions of the certificate of designations that prohibit us from, at our
option, redeeming the shares of our series LMCN-V common stock.

    The vote of the holders of shares of our series LMCN-V common stock is not
required for us to:

     create any indebtedness;

     authorize or issue any class of capital stock that is senior to, or on a
     parity with, our series LMCN-V common stock with respect to the payment of
     dividends or any other distribution of assets;

     approve any amendment to our restated certificate of incorporation that
     would increase or decrease the aggregate number of authorized shares of our
     series common stock or our common stock; or

     authorize any increase or decrease in the number of shares constituting our
     series LMCN-V common stock.

    Cash Dividends. Holders of our series LMCN-V common stock are entitled to
receive cash dividends when and if declared by our board of directors, but only
to the extent that regularly scheduled cash dividends are declared and paid on
our common stock. When declared, cash dividends on each share of our series
LMCN-V common stock will equal the product of:

     the amount of the regularly scheduled cash dividend to be paid on one share
     of our common stock; multiplied by

     the LMCN-V formula number in effect on the dividend payment date.

    Distributions. If we distribute to the holders of our common stock any
assets or property, in each case not including a distribution upon the
liquidation of our company, a regularly scheduled cash dividend or a common
stock dividend that results in an adjustment of the LMCN-V formula number, then
we must at the same time distribute the same assets or property pro rata to the
holders of our series LMCN-V common stock in an amount equal to the amount that
the holders of our series LMCN-V common stock would have been entitled to
receive had they converted their shares of our series LMCN-V common stock into
shares of our common stock immediately prior to the record date for the
distribution.

                                       25





    Conversion Rights. Holders of our series LMCN-V common stock have the right
to convert each of their shares, at any time, into:

     a number of shares of our common stock equal to the LMCN-V formula number
     in effect on the conversion date; or

     one share of our series LMC common stock.

Each holder of our series LMCN-V common stock may convert shares of our series
LMCN-V common stock into shares of our common stock or our series LMC common
stock only to the extent that the ownership by the converting holder of shares
of our common stock or our series LMC common stock upon conversion would not
violate the federal communications laws.

    Conversion Rate Adjustment. If we consolidate or merge with another entity
such that we are not the surviving entity or the transaction results in a change
in our common stock, or if we sell all or substantially all of our property and
assets to another entity, each share of our series LMCN-V common stock is
convertible into the number of shares of capital stock or other property
received by the holder of a number of shares of our common stock into which the
shares of our series LMCN-V common stock could have been converted immediately
before the transaction.

    Liquidation Rights. In the event of the liquidation of our company, the
holders of our series LMCN-V common stock are entitled to receive, at the same
time as any distribution to holders of our common stock, an aggregate amount per
share equal to the product of:

     the aggregate amount to be distributed per share to holders of our common
     stock; and

     the LMCN-V formula number in effect on the date of the distribution.

    Transfer Restriction. Holders of our series LMCN-V common stock are subject
to a transfer restriction that prevents these holders, without obtaining prior
consent from us, from transferring their shares of our series LMCN-V common
stock to any person other than a 'permitted transferee'. The transfer
restriction applicable to holders of our series LMCN-V common stock is identical
to the transfer restriction applicable to holders of our series LMC common
stock. See 'Series LMC Common Stock -- Transfer Restriction'.

                              PLAN OF DISTRIBUTION

    We may sell the debt securities, preferred stock, series common stock,
common stock or warrants (together referred to as the 'offered securities') to
one or more underwriters or dealers for public offering and sale by them or may
sell the offered securities to investors directly, including through the
Internet, or through agents. The prospectus supplement with respect to the
offered securities offered thereby, describes the terms of the offering of such
offered securities and the method of distribution of the offered securities
offered thereby and identifies any firms acting as underwriters, dealers or
agents in connection therewith.

    The offered securities may be distributed from time to time in one or more
transactions at a fixed price or prices (which may be changed) or at prices
determined as specified in the prospectus supplement. In connection with the
sale of the offered securities, underwriters, dealers or agents may be deemed to
have received compensation from us in the form of underwriting discounts or
commissions and may also receive commissions from purchasers of the offered
securities for whom they may act as agent. Underwriters may sell the offered
securities to or through dealers, and such dealers may receive compensation in
the form of discounts, concessions or commissions from the underwriters or
commissions from the purchasers for whom they may act as agent. Certain of the
underwriters, dealers or agents who participate in the distribution of the
offered securities may engage in other transactions with, and perform other
services for us, America Online, Time Warner, TWC and TBS in the ordinary course
of business.

    Any underwriting compensation paid by us to underwriters or agents in
connection with the offering of the offered securities, and any discounts,
concessions or commissions allowed by underwriters to dealers, are set forth in
the prospectus supplement. Underwriters, dealers and agents participating in the
distribution of the offered securities may be deemed to be underwriters, and any
discounts and commissions received by them and any profit realized by them on
the resale of the offered securities may be deemed to be underwriting discounts
and commissions under the Securities Act. Underwriters and their controlling
persons, dealers and agents may be entitled, under agreements entered into with
us, to indemnification against and contribution toward certain civil
liabilities, including liabilities under the Securities Act.

    Certain persons participating in this offering may engage in transactions
that stabilize, maintain or otherwise affect the price of the securities,
including over-allotment, stabilizing and short-covering transactions in such
securities, and the imposition of a penalty bid, in connection with the
offering.

                                 LEGAL OPINIONS

    Certain legal matters in connection with the offered securities will be
passed upon for us, America Online, Time Warner, TWC and TBS by Cravath, Swaine
& Moore, Worldwide Plaza, 825 Eighth Avenue, New York, New York 10019.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    AOL Time Warner. Section 145(a) of the General Corporation Law of the State
of Delaware ('Delaware Corporation Law') provides, in general, that a
corporation shall have the power to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation),
because the person is or was a director or officer of the corporation. Such
indemnity may be against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding, if the person acted in good
faith and in a manner the person reasonably believed to be in or not opposed to
the best interests of the corporation and if, with respect to any criminal
action or proceeding, the person did not have reasonable cause to believe the
person's conduct was unlawful.

    Section 145(b) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor because the person is or was a director or officer of the corporation,
against any expenses (including attorneys' fees) actually and reasonably
incurred by the person in connection with the defense or settlement of such
action or suit if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnify for such expenses which the Court of Chancery or such other court
shall deem proper.

    Section 145(g) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to purchase and maintain insurance on behalf of
any person who is or was a director or officer of the corporation against any
liability asserted against the person in any such capacity, or arising out of
the person's status as such, whether or not the corporation would have the power
to indemnify the person against such liability under the provisions of the law.

    Article VI of AOL Time Warner's by-laws requires indemnification to the
fullest extent permitted under Delaware law or other applicable law or any
person who is or was a director or officer of AOL Time Warner who is or was
involved or threatened to be made so involved in any action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that such person is or was serving as a director, officer, employee or agent of
AOL Time

                                      II-1





Warner or was serving at the request of AOL Time Warner as a director, officer,
employee or agent of any other enterprise; provided, however, that the foregoing
shall not apply to a director or officer with respect to a proceeding that was
commenced by such director or officer unless under certain circumstances.

    Article VI of AOL Time Warner's by-laws authorizes AOL Time Warner to
purchase and maintain insurance on behalf of its directors, officers, employees
and agents. AOL Time Warner's Directors' and Officers' Liability and
Reimbursement Insurance Policy is designed to reimburse each of the registrants
for any payments made pursuant to these indemnification provisions.

    The foregoing statements are subject to the detailed provisions of Section
145 of the Delaware Corporation Law and Article VI of the by-laws of AOL Time
Warner.

    America Online. Article NINTH of the restated certificate of incorporation
and Article V of the restated by-laws of America Online provide that any person
who was or is a party or is threatened to be a party to, or is involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative, because that person is or was a director or officer, or is or was
serving at the request of America Online as a director, officer, employee or
agent of another corporation or of a partnership, joint venture, trust or other
enterprise, will be indemnified and held harmless by America Online to the
fullest extent permitted by Delaware law. The indemnification rights conferred
by America Online are not exclusive of any other right to which persons seeking
indemnification may be entitled under any statute, America Online's restated
certificate of incorporation or restated by-laws, any agreement, vote of
stockholders or disinterested directors or otherwise. America Online is
authorized to purchase and maintain insurance on behalf of its directors and
officers.

    In addition, America Online may pay expenses incurred by its directors and
officers in defending a civil or criminal action, suit or proceeding because
they are directors or officers in advance of the final disposition of the
action, suit or proceeding. The payment of expenses will be made only if America
Online receives an undertaking by or on behalf of a director or officer to repay
all amounts advanced if it is ultimately determined that the director or officer
is not entitled to be indemnified by America Online, as authorized by America
Online's restated certificate of incorporation and restated by-laws.

    Time Warner. Article VI of the Time Warner by-laws provide for
indemnification, to the fullest extent permitted by Delaware law, of any person
who is or was a director or officer of Time Warner and who is or was involved in
any manner, or who is threatened to be made involved in any manner, in any
threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he or she is or was a director, officer, employee or agent of
Time Warner, or is or was serving at the request of Time Warner as a director,
officer, employee or agent of another corporation, or of a partnership, joint
venture, trust or other enterprise; provided, however, that the foregoing shall
not apply to a director or officer with respect to a proceeding that was
commenced by such director or officer unless under certain circumstances. Time
Warner is authorized to purchase and maintain insurance on behalf of its
directors, officers, employees and agents. The indemnification rights conferred
by Time Warner are not exclusive of any other right to which persons seeking
indemnification may be entitled.

    In addition, the Time Warner by-laws provide that all reasonable expenses
incurred by or on behalf of a director or officer in connection with any
investigation, claim, action, suit or proceeding will be advanced to the
director or officer by Time Warner upon the request of the director or officer,
which request, if required by law, will include an undertaking by or on behalf
of the director or officer to repay the amounts advanced if ultimately it is
determined that the director or officer was not entitled to be indemnified
against the expenses.

    TWC. Article IV of TWC's by-laws require indemnification, to the fullest
extent permitted under Delaware law, of any person who is or was a director or
officer of TWC and who is or was involved, or who is threatened to be made so
involved, in any threatened, pending or completed investigation, claim, action,
suit or proceeding, whether criminal, civil, administrative or

                                      II-2





investigative, by reason of the fact that such person is or was serving as a
director, officer or employee of TWC or any predecessor of TWC or was serving at
the request of TWC as a director, officer or employee of any other enterprise.
The indemnification rights conferred by TWC are not exclusive of any other right
to which persons seeking indemnification may be entitled under any statute. TWC
is authorized to purchase and maintain insurance on behalf of its directors,
officers, employees and agents. In addition, the TWC by-laws provide that all
reasonable expenses incurred by or on behalf of a director or officer in
connection with any investigation, claim, action, suit or proceeding will be
advanced to the director or officer by TWC upon the request of the director or
officer, which request, if required by law, will include an undertaking by or on
behalf of the director or officer to repay the amounts advanced if ultimately it
is determined that the director or officer was not entitled to be indemnified
against the expenses.

    TBS. Article VIII of TBS's by-laws provide for indemnification of directors
and officers of TBS in connection with or resulting from any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, in which he or she may become involved by reason of his or her
being or having been a director or officer, or a director or officer of any such
other enterprise. Such indemnification shall be made only in accordance with the
laws of the state of Georgia and subject to the conditions prescribed therein.

    As a condition to any such right of indemnification, TBS may require that it
be permitted to participate in the defense through legal counsel designated by
TBS and at the expense of TBS. TBS may purchase and maintain insurance on behalf
of its directors and officers, whether or not TBS would have the power to
indemnify such directors and officers under the laws of the State of Georgia.

    Article 9 of TBS's articles of incorporation provides that a director of TBS
will not be personally liable to TBS or its shareholders for monetary damages
for breach of duty of care or other duty as a director, except for liability
(i) for any appropriation, in violation of the director's duties, of any
business opportunity of TBS; (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law; (iii) for
the types of liability set forth in Section 14-2-154 of the Georgia Business

ITEM 17. UNDERTAKINGS

A. UNDERTAKINGS PURSUANT TO RULE 415

    The undersigned registrants hereby undertake:

        (a) 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 or 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) ('SS'203.424(b) of this chapter) if,
       in the aggregate, the changes in volume and price represent 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 this registration statement or
       any material change to such information in this registration statement;

   provided, however, that the undertakings set forth in clauses (a)(i) and
   (a)(ii) do not apply if the information required to be included in a
   post-effective amendment by those clauses is contained in periodic reports
   filed by the registrants pursuant to Section 13 or Section 15(d) of the
   Exchange Act that are incorporated by reference in the registration
   statement;

        (b) 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 that time shall be deemed to be the
    initial bona fide offering thereof; and

        (c) 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.

B. UNDERTAKING REGARDING FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS
   BY REFERENCE

    The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act, each filing of any of the
registrants' annual reports pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the 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.

C. UNDERTAKING IN RESPECT OF INDEMNIFICATION

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrants pursuant to the provisions described in Item 15 above, or otherwise,
the registrants have been advised that in the opinion of the 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 registrants of expenses
incurred or paid by a director, officer or controlling person of the registrants
in the successful defense of any action, suit or proceeding) is asserted by such
officer, director or controlling person in connection with the securities being
registered, the registrants 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 of 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.
