     We issued the warrants and the securities that were exchanged for the
offered preferred stock in May 1998 to the selling securityholders named on
pages 69 and 71 in a private placement. We made this private placement under an
investment agreement, dated as of February 23, 1998, between Oxford and TPG

investment agreement as an exhibit to the registration statement of which this
prospectus is a part.

                                           June 2000; and


                                         - on May 13, 2000, we may choose to
                                           make payments of dividends in cash or
                                           by the issuance of additional shares
                                           of Series D preferred stock; after
                                           May 13, 2000, payments of dividends
                                           must be in cash.

                                    entitled to receive dividends in the

                                         - an annual dividend payment in the
                                           form of Series E preferred stock was
                                           made on May 13, 1999.

                                    ON OR AFTER MAY 13, 2000:

                                         - shares of Series E preferred stock

                                           dividends are payable in equal
                                           quarterly installments on the last

                                         - on May 13, 2000, we may choose to
                                           make payments of dividends in cash or
                                           by the issuance of additional shares

Limitations on Payment of
Dividends.......................    We may only pay dividends out of funds
                                    legally available under Delaware law. In
                                    addition, we are subject to restrictive
                                    covenants that may limit our ability to pay
                                    dividends. See "Description of Term Loan and
                                    Senior Notes" beginning on page 62 for a
                                    description of these covenants. If we fail
                                    to pay dividends when due, we will not be
                                    released from our obligation to make that
                                    dividend payment and additional dividends
                                    will accumulate on the missed payment.

Ranking.........................    With respect to the right to receive
                                    dividends and payments upon the liquidation,
                                    dissolution or winding up of Oxford, the
                                    offered preferred stock ranks:

                                         - senior to our common stock and,
                                           except as specified below, any other
                                           class or series of capital stock that
                                           we issue in the future;

                                         - equally with each other class or
                                           series of preferred stock which
                                           provides that it ranks equally with
                                           the offered preferred stock; and

                                         - junior to each other class of
                                           preferred stock which provides that
                                           it ranks senior to the offered
                                           preferred stock.

                                    Currently, there are no classes of preferred
                                    stock issued or outstanding that rank senior
                                    to the Series D preferred stock or the
                                    Series E preferred stock. The Series D
                                    preferred stock and the Series E preferred
                                    stock have the same ranking, and there are
                                    currently no other classes of preferred
                                    stock that have the same ranking as the
                                    Series D preferred stock and Series E
                                    preferred stock. The holders of each series
                                    of offered preferred stock must consent for
                                    Oxford to be able to create a class of
                                    preferred stock that ranks the same or that
                                    ranks senior to that class of offered
                                    preferred stock.

Liquidation Preference..........    Upon liquidation, dissolution or winding up
                                    of Oxford, each holder of shares of offered
                                    preferred stock is entitled to receive the
                                    following amount before we make any payment
                                    on securities that rank junior to the
                                    offered preferred stock:

                                         - dividends, if any, accumulated or
                                           deemed to have accumulated on each
                                           share of offered preferred stock held
                                           by the holder to the date we make
                                           liquidation distributions, whether or
                                           not declared, and

                                         - the stated value of each share of
                                           offered preferred stock held by the
                                           holder, which is $1,000.

                                    If the assets or proceeds from a
                                    liquidation, dissolution or winding up of
                                    Oxford are insufficient to make these
                                    payments, then we will distribute the assets
                                    and proceeds ratably among holders of
                                    offered preferred stock and any securities
                                    that have the same ranking as the offered
                                    preferred stock.

Optional Redemption.............    We have the right to redeem all outstanding
                                    shares of a series of offered preferred
                                    stock on or after May 13, 2003, at a
                                    redemption price for each share
                                        4
<PAGE>   9

                                    of that series equal to all unpaid dividends
                                    accumulated to the date of payment of the
                                    redemption price, plus the stated value of
                                    the share, which is $1,000.


Change of Control Redemption....    If a "change of control" occurs with respect
                                    to Oxford, holders of offered preferred
                                    stock may require us to redeem any or all of
                                    the shares of offered preferred stock that
                                    they hold, at a redemption price for each
                                    share equal to all unpaid dividends
                                    accumulated to the date of payment of the
                                    redemption price, plus the stated value of
                                    the share, which is $1,000.


                                    Generally, a change of control may occur
                                    upon events such as:

                                         - a merger or consolidation of Oxford;

                                         - acquisition of majority control of
                                           Oxford by a person;

                                         - a sale, lease or other transfer of
                                           substantially all of our assets;

                                         - a substantial change in our board of
                                           directors; or

                                         - adoption of a plan of liquidation or
                                           dissolution.


                                    For a more complete definition of a "change
                                    of control," please see the section of this
                                    prospectus entitled "Description of the
                                    Offered Preferred Stock -- Change of Control
                                    Redemption" beginning on page 18.



                                    Our ability to redeem offered preferred
                                    stock upon a change of control may be
                                    limited by the agreements that we have made
                                    and the various restrictive covenants under
                                    our term loan agreement and under the
                                    indenture that governs our 11% Senior Notes
                                    due 2005. For a description of these
                                    limitations, see "Description of Term Loan
                                    and Senior Notes" beginning on page 62. If
                                    we are required to redeem offered preferred
                                    stock and we fail to pay the redemption
                                    price on the redemption date, we will not be
                                    released from our obligation to pay the
                                    redemption price, and dividends will
                                    accumulate on the missed payment.



Exchange........................    On any dividend payment date, we have the
                                    right to exchange Series D preferred stock
                                    for Series D debentures or Series E
                                    preferred stock for Series E debentures.
                                    Each series of debentures will be issued
                                    pursuant to an indenture. We will not
                                    exchange offered preferred stock for
                                    debentures before May 13, 2000.

                                    Unless all holders of shares of the series
                                    of offered preferred stock to be exchanged
                                    consent, we may effect an exchange only if:


                                         - we have paid or set aside for payment
                                           full cumulative dividends on all
                                           outstanding shares of the series of
                                           offered preferred stock to be
                                           exchanged;


                                         - we have amended our certificate of
                                           incorporation to give holders of the

                                           that they had as holders of offered
                                           preferred stock; and



                                         - the exchange could not result in any
                                           materially adverse tax consequence to

                                    The indentures that will govern the
                                    debentures will have terms comparable to the
                                    terms of the series of offered preferred
                                    stock that is exchanged, including an
                                    interest rate that is the same as the
                                    dividend rate on the series of offered
                                    preferred stock that is exchanged. These

Limited Voting Rights...........    Holders of offered preferred stock, other
                                    than TPG Partners II, one of the selling
                                    securityholders, and its affiliates,
                                    generally will not have the right to vote,
                                    unless:

                                         - dividends are in arrears and we have
                                           not paid dividends in full on May 13,
                                           2000;

                                         - dividends are in arrears and we have
                                           not paid dividends in full for four
                                           consecutive quarters; or

                                         - we fail to redeem shares of offered
                                           preferred stock when required to do
                                           so.


                                    Generally, if any of the above events occur,
                                    then the number of directors on our board of
                                    directors automatically will be increased by
                                    two, and the holders of a majority of the
                                    outstanding shares of offered preferred
                                    stock will have the exclusive right, voting
                                    together as a single class, to elect the two
                                    new directors. However, there are
                                    limitations on this right, which are
                                    described in the section of this prospectus
                                    entitled "Description of the Offered

                                    be entitled to receive debentures with a
                                    principal amount equal to $1,000 in exchange
                                    for each share of the offered preferred

                                    debentures will bear interest at a rate of
                                    14% per year.

                                    series of debentures in equal quarterly
                                    installments on the last day of March, June,
                                    September and December of each year.



Subordination...................    The indebtedness evidenced by the debentures
                                    will be subordinated in right of payment to
                                    the prior payment in full of all "senior
                                    indebtedness." Senior indebtedness generally
                                    includes:



                                         - our outstanding 11% Senior Notes due
                                           2005;



                                         - any indebtedness now or hereafter
                                           issued or incurred by us under the
                                           term loan agreement described in this
                                           prospectus under "Description of Term
                                           Loan and Senior Notes" beginning on
                                           page 62; and



                                         - any other indebtedness now or
                                           hereafter incurred by us, unless the
                                           instrument under which that
                                           indebtedness is incurred expressly
                                           provides that it is not superior in
                                           right of payment to the debentures of
                                           that series, excluding liability for
                                           taxes, indebtedness to our
                                           subsidiaries or other affiliates,
                                           trade payables, or the debentures of
                                           the other series.



                                    Each series of debentures will rank equally
                                    with or will be senior to all other
                                    indebtedness of Oxford and will rank equally
                                    with, and not senior to, each other.

                                    Upon certain bankruptcy and similar events
                                    relating to Oxford, holders of senior
                                    indebtedness will be entitled to receive
                                    payment in full of the senior indebtedness
                                    before the holders of the debentures will be
                                    entitled to receive any payment of principal
                                    or interest on the debentures, subject to
                                    certain exceptions. In addition, no payment
                                    may be made to holders of debentures when
                                    certain defaults have occurred and are
                                    continuing with respect to the senior
                                    indebtedness, subject to certain exceptions.



                                    As of the date of this prospectus, we had
                                    approximately $150 million outstanding under
                                    the term loan agreement and $200 million
                                    aggregate principal amount of 11% Senior
                                    Notes due 2005 outstanding.



                                    The indentures relating to each series of
                                    debentures do not contain restrictions on
                                    our ability to incur additional
                                    indebtedness.



Optional Redemption.............    We have the right to redeem all outstanding
                                    debentures of a series on or after May 13,
                                    2003, at a redemption price for each
                                    debenture of that series of 100% of the
                                    principal amount of the debenture to be
                                    redeemed, plus accrued and unpaid interest
                                    on the debenture to the redemption date.



Change of Control Redemption....    If a "change of control" occurs with respect
                                    to Oxford, holders of debentures may require
                                    us to redeem any or all of the debentures
                                    that they hold, at a redemption price for
                                    each debenture equal to 100% of the
                                    principal amount of the debenture to be
                                    redeemed, plus accrued and unpaid interest
                                    on the debenture to the redemption date.
                                    Events that constitute a "change of control"
                                    generally are described above in "-- Terms
                                    of the Offered Preferred Stock" and a more
                                    complete definition is contained in the
                                    section of this prospectus entitled
                                    "Description of the Offered Preferred

                                    Our ability to redeem debentures upon a
                                    change of control may be limited by the
                                    agreements that we have made and the various
                                    restrictive covenants under our term loan
                                    agreement and under the indenture that
                                    governs our 11% Senior Notes due 2005. For a
                                    description of these limitations, see
                                    "Description of Term Loan and Senior Notes"
                                    beginning on page 62. If we are required to
                                    redeem debentures and we fail to pay the
                                    redemption price

                                    on the redemption date, we will not be
                                    released from our obligation to pay the
                                    redemption price, and interest will accrue
                                    on the missed payment.



Limited Voting Rights...........    Holders of debentures will have voting
                                    rights that are substantially similar to the
                                    voting rights that the holders of offered
                                    preferred stock have. Holders of debentures,
                                    other than TPG Partners II, one of the
                                    selling securityholders, and its affiliates,
                                    generally will not have the right to vote,
                                    unless:



                                         - interest due and payable on either
                                           series of debentures has not been
                                           paid in full or, if one series of
                                           offered preferred stock has not been
                                           exchanged for debentures, the
                                           dividends payable on that series of

                                           arrears and not paid in full, for
                                           four consecutive quarterly periods;
                                           or



                                         - we fail to redeem or repay either
                                           series of debentures when required to
                                           do so or, if one series of offered
                                           preferred stock has not been
                                           exchanged for debentures, we fail to
                                           redeem shares of that series of
                                           offered preferred stock when required
                                           to do so.



                                    Generally, if any of the above events occur,
                                    then the number of directors on our board of
                                    directors automatically will be increased by
                                    two, and the holders of a majority in
                                    aggregate principal amount of outstanding
                                    debentures of both series will have the
                                    exclusive right, voting together as a single
                                    class, to elect the two additional
                                    directors. If one series of offered
                                    preferred stock has not been exchanged for
                                    debentures, then holders of debentures shall
                                    vote with holders of the series of offered
                                    preferred stock that has not been exchanged
                                    as a single class to elect the two
                                    additional directors. However, there are
                                    limitations on this right, which are
                                    described in "Description of the
                                    Debentures -- Voting Rights" beginning on
                                    page 36.



Restrictions on Dividends.......    The indentures will contain limited
                                    restrictions on our ability to pay dividends
                                    or make any payment on our capital stock.

Shelf Registration Statement....    Under the registration rights agreement,
                                    dated as of February 23, 1998, between us

                                    until:

                                         - 10 years after the date it is first
                                           declared effective; or

                                           investment agreement and are

                                    Generally, we intend the shelf registration

                                    once sold under the shelf registration
                                    statement, the registrable securities should
                                    be freely tradeable except by purchasers who
                                    are our "affiliates" or are "underwriters"

     The ratio of earnings to combined fixed charges and preference dividends

* Earnings were insufficient to cover fixed charges and preference dividends by
  $642.9 million for the year ended December 31, 1998, $431.6 million for the
  year ended December 31, 1997 and $622.2 million for the nine months ended
  September 30, 1998.



     For purposes of computing these ratios, we increased our combined earnings
before income taxes, as reported in our annual report on Form 10-K/A No. 2 for
the year ended December 31, 1998, as amended by our Form 10-K/A No. 3, and in
our quarterly report on Form 10-Q for the quarter ended September 30, 1999, by
the amount of our fixed charges. We then divided the amount of earnings by the
amount of fixed charges and preference dividends, resulting in the ratio of
earnings to combined fixed charges and preference dividends. Fixed charges
represent interest expense plus the estimated interest factor in rental expense.
We have not capitalized interest in any period.

     We provide health care benefit plans through our HMO and insurance

       contract with us;

     - health care benefit plans for Medicare beneficiaries;

     - health care benefit plans, known as point-of-service plans, which provide
       the member with the option of using a provider who is under contract with
       us or one who is not under contract with us;

     - health care benefit plans, known as preferred provider organizations,
       which permit the member to choose any health care provider;

also have contracts with groups of providers such as physician hospital
organizations, individual practice associations and other physician groups. We

to some of our Medicare beneficiaries as well as for pharmacy benefits

prospectus by reference.


                   DESCRIPTION OF THE OFFERED PREFERRED STOCK


     The following summarizes certain terms and provisions of the Series D
preferred stock and the Series E preferred stock. This summary is not complete
and is subject to, and qualified in its entirety by reference to, applicable
Delaware law and to the provisions of our certificate of incorporation, by-laws
and the certificates of designations designating the Series D preferred stock
and the Series E preferred stock. These documents are filed as exhibits to the
registration statement of which this prospectus is a part.


AUTHORITY TO ISSUE PREFERRED STOCK


     Our certificate of incorporation authorizes our board of directors to
issue, without the approval of the stockholders, up to 2,000,000 shares of
preferred stock, $.01 par value. As of the date of this prospectus, we:



     - had designated 300,000 shares of Series D Cumulative Preferred Stock, par
       value $.01 per share, which we refer to as the "Series D preferred
       stock," and had issued 263,606.551 shares of Series D preferred stock;
       and


                                       13
<PAGE>   18


     - had designated 300,000 shares of Series E Cumulative Preferred Stock, par
       value $.01 per share, which we refer to as the "Series E preferred
       stock," and had issued 115,899.276 shares of Series E preferred stock.



     We expect to issue an additional 14,022.606 shares of Series D preferred
stock and 16,908.793 shares of Series E preferred stock as dividends on the
existing shares of offered preferred stock through May 13, 2000.


     Before issuing a series of preferred stock, our board of directors has the
right to designate, for that series of preferred stock:

     - the serial designations;

     - dividend rates;

     - the offering price or prices;

     - provisions for redemption or purchase;

     - provisions for conversion;

     - voting rights;

     - special or relative rights in the event of a liquidation, distribution or
       sale of assets or dissolution or winding up;

     - provisions for a sinking fund; and

     - any other rights, obligations or provisions which may be so determined to
       the fullest extent permitted by Delaware law.


     As described below, our board of directors cannot create any class of
capital stock with a ranking equal to or senior to the offered preferred stock
or that is redeemable on or before May 13, 2008 without the consent of the
holders of a majority of the shares of each series of the offered preferred
stock.


GENERAL

     The stated value of the offered preferred stock is $1,000 per share. The
offered preferred stock does not provide holders with preemptive rights. The
terms of the Series D preferred stock and Series E preferred stock are
substantially similar except for their dividend rates and as noted specifically
below.

     Under the investment agreement, the selling securityholders named in this
prospectus purchased 245,000 shares of our Series A Cumulative Preferred Stock,
which we refer to as the "Series A preferred stock," 105,000 shares of our
Series B Cumulative Preferred Stock, which we refer to as the "Series B
preferred stock," Series A Warrants to purchase 15,800,000 shares of our common
stock, par value $.01 per share, and Series B Warrants to purchase 6,730,000
shares of our common stock for a total purchase price of $350 million. On
February 13, 1999, we entered into a share exchange agreement with the selling
securityholders to redistribute the total amount of dividends payable among the
shares of Series A preferred stock and Series B preferred stock. Under the share
exchange agreement, the 245,000 shares of Series A preferred stock were
exchanged for 260,146.909 shares of Series D preferred stock, and the 105,000
shares of Series B preferred stock were exchanged for 111,820.831 shares of
Series E preferred stock. The additional amounts of Series D preferred stock and
Series E preferred stock issued in the exchange are attributable to dividends
accrued on the Series A preferred stock and the Series B preferred stock,
respectively, through February 13, 1999. As a result of the exchange, the

                                       14
<PAGE>   19


selling securityholders hold only Series D preferred stock and Series E
preferred stock and, following the exchange, all shares of the Series A
preferred stock and Series B preferred stock were canceled. The terms of the
Series D preferred stock are substantially similar to the terms of the Series A
preferred stock and the terms of the Series E preferred stock are substantially
similar to the terms of the Series B preferred stock, except, in each case, with
respect to applicable dividend rates and their use as consideration for the
exercise of the warrants. The exchange was effected primarily to facilitate the
potential sale of the offered preferred stock by the selling securityholders.



     We conduct our operations primarily through our subsidiaries. Therefore,
our ability to make required dividend payments depends in part on the earnings
of our subsidiaries and on our ability to receive funds from our subsidiaries
through dividends or other payments. Because payments due on the offered
preferred stock are obligations of Oxford alone, our subsidiaries are not
obligated to pay any amount due under the offered preferred stock or to make
funds available for dividends on the offered preferred stock in the form of
dividends or advances to us. In addition, various insurance and health
regulations applicable to our subsidiaries restrict their ability to pay
dividends to us. If we incur operating losses, we may be required to make
additional capital contributions to our subsidiaries in order to comply with
statutory capital requirements and the payment of dividends by those
subsidiaries would likely not be permitted.



     In addition, the offered preferred stock effectively is subordinated to all
outstanding indebtedness and other liabilities and commitments, including
accounts payable and other accrued liabilities, of our subsidiaries. Any right
we have to receive assets of one of our subsidiaries upon its liquidation or
reorganization, and the resulting right of holders of the offered preferred
stock to participate in those assets, effectively will be subordinated to the
claims of that subsidiary's creditors, except to the extent we are recognized as
a creditor of that subsidiary. If we are recognized as a creditor of that
subsidiary, our claims would still be subordinated to any security interest in
the assets of the subsidiary and any indebtedness of the subsidiary that is
senior to indebtedness held by us.


     ChaseMellon Shareholder Services, L.L.C. will be the transfer agent,
dividend disbursing agent and registrar for the offered preferred stock unless
otherwise specified in a prospectus supplement.

RANKING

     With respect to the right to receive dividends and payments upon the
liquidation, dissolution or winding up of Oxford, the offered preferred stock
ranks:

     - senior to our common stock and, except as specified below, any other
       class or series of our capital stock we issue in the future;

     - equally with each other class or series of preferred stock which by its
       terms provides that it ranks equally with the offered preferred stock;
       and

     - junior to each other class of preferred stock which by its terms provides
       that it ranks senior to the offered preferred stock.

     Currently, there are no classes of preferred stock issued or outstanding
that rank senior to the Series D preferred stock or the Series E preferred
stock. The Series D preferred stock and the Series E preferred stock have the
same ranking, and there are currently no other classes of preferred stock that
have the same ranking as the Series D preferred stock and Series E preferred
stock. The consent of holders of each series of

                                       15
<PAGE>   20

offered preferred stock is required for Oxford to be able to create a class of
preferred stock that has the same ranking or that is senior to that class of
offered preferred stock.

MANDATORY REDEMPTION


     On May 13, 2008, we are required to redeem all outstanding shares of the
offered preferred stock. For a description of the redemption price and
redemption procedures, see "-- Redemption Price and Procedures" beginning on
page 19.

</TABLE>


     If any date specified as a dividend payment date is not a business day, we
will pay the dividends due on the next business day, without interest. We will
pay dividends to holders of record as they appear on our stock record books 15
days prior to the relevant dividend payment date.

                                       16
<PAGE>   21


     We will pay dividends only when, as and if declared by our board of
directors, out of funds at the time legally available for the payment of
dividends under the Delaware General Corporation Law. In addition, we are
subject to various restrictive covenants that may limit our ability to pay
dividends on the offered preferred stock. See "Description of Term Loan and
Senior Notes" beginning on page 62 of this prospectus. If we fail to pay
dividends when due, we will not be released from our obligation to make that
dividend payment and additional dividends will accumulate on the missed payment.


On May 13, 1999, we issued:

(a) a dividend in the amount of $13.29880250 per share of Series D preferred
    stock in the form of 3,459.64236379 shares of Series D preferred stock to
    the holders of record as of April 28, 1999; and

(b) a dividend in the amount of $36.47303500 per share of Series E preferred
    stock in the form of 4,078.44508277 shares of Series E preferred stock to
    the holders of record as of April 28, 1999.


     These payments reflected dividends accumulated from February 13, 1999, the
date the offered preferred stock was issued in exchange for the Series A
preferred stock and the Series B preferred stock. Dividends that accumulated on
the Series A preferred stock and Series B preferred stock from May 13, 1998
through February 13, 1999 were satisfied by the issuance of additional shares of
Series D preferred stock and Series E preferred stock in the exchange. We have
paid all accrued dividends required to be paid on the offered preferred stock to
the date of this prospectus.


  ACCUMULATION OF DIVIDENDS

     Dividends began to accumulate on outstanding shares of the offered
preferred stock from the date of issuance, and accumulate day-to-day, whether or
not earned or declared, until the dividends are paid. Dividends accumulate on
the basis of a 360-day year consisting of twelve 30-day months and the actual
number of days elapsed in the period for which payable. Dividends payable at
more than one annual rate for any dividend period or partial dividend period
will be pro rated based on the number of days in the dividend period or partial
dividend period, and the actual number of days elapsed for which dividends are
payable, at the applicable annual rate.

  ADDITIONAL DIVIDENDS


     Whenever we do not pay in full any dividend that has accumulated through
any dividend payment date, or whenever we do not pay in full any redemption
payment on any payment date set for a redemption, additional dividends will
accumulate on the amount of the unpaid dividends or the unpaid redemption
payment. An unpaid amount is referred to as an "arrearage." Additional dividends
accumulate on an arrearage at the annual dividend rate then in effect or a
lesser rate as may be the maximum rate that is then permitted by applicable law.
Additional dividends in respect of any arrearage:


     - will accumulate day-to-day, whether or not earned or declared, until the
       arrearage is paid; and

     - will be calculated as of each successive dividend payment date and will
       constitute an additional arrearage from and after any dividend payment
       date to the extent not paid on that dividend payment date.

     We may declare and pay additional dividends in respect of any arrearage at
any time, in whole or in part, without reference to any regular dividend payment
date, to registered

                                       17
<PAGE>   22

holders as they appear on our stock record books on the record date fixed by our
board of directors. The record date must be at least 10 days before the
corresponding payment date. Repayment of any arrearage must be made in cash.

  METHOD OF PAYMENT

     If we pay less than the total amount of accumulated dividends payable on
all outstanding shares of a series of offered preferred stock, then we will
allocate dividends pro rata on a share-by-share basis among all outstanding
shares of that series. Once dividends are payable in cash, dividends that we
declare and pay in an amount less than the full amount of dividends accumulated
on a series of the offered preferred stock and on any arrearage will be applied
first to the earliest dividend that has not yet been paid. We will make all cash
payments of dividends on the offered preferred stock in United States dollars.

LIQUIDATION PREFERENCES

     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of Oxford, a holder of offered preferred stock will be entitled to
receive out of the assets of Oxford, before we make any payment or distribute
any assets to the holders of any securities that rank junior to the offered
preferred stock, an amount per share equal to the sum of:

     (1) the dividends, if any, accumulated on the offered preferred stock to
         the date we make liquidation distributions, whether or not dividends
         have been declared; and


     (2) the stated value of the share of offered preferred stock, which is
         $1,000.


     If these assets or proceeds are insufficient to satisfy all claims with the
same priority of payment as the offered preferred stock, then we will distribute
the available assets and proceeds ratably among the holders of the offered
preferred stock and any securities that have the same priority of payment as the
offered preferred stock. After we pay holders the full amount of the liquidation
preference to which they are entitled, they will not be entitled to participate
in any further distribution of our assets. Neither a consolidation nor merger of
Oxford nor a sale, conveyance, lease, exchange or transfer of all or part of
Oxford's assets will be a liquidation, dissolution or winding up of Oxford.

OPTIONAL REDEMPTION


     On and after May 13, 2003, we have the right to redeem all the outstanding
shares of a series of the offered preferred stock, in whole but not in part, in
accordance with the procedures described under "-- Redemption Price and
Procedures" beginning on page 19.


CHANGE OF CONTROL REDEMPTION

     If a "change of control" occurs, then holders of offered preferred stock
may require us to redeem any or all of their shares of offered preferred stock.

       A "change of control" means the time that any of the following occurs:

       (1) any person or group other than TPG Partners II, its affiliates,
           Oxford or any of our subsidiaries, or any group comprised of those
           persons, becomes, directly or indirectly, the beneficial owner, by
           way of merger, consolidation or otherwise, of a majority of the
           then-outstanding securities of Oxford entitled to vote in an election
           of directors. This determination will be made after giving effect to
           the

                                       18
<PAGE>   23


           conversion and exercise of all outstanding warrants, options and
           other securities of Oxford convertible into or exercisable for
           securities of Oxford entitled to vote in an election of directors,
           whether or not the securities are then convertible or exercisable;


       (2) the sale, lease, transfer or other disposition of all or
           substantially all of the assets of Oxford and our subsidiaries to any
           person or group;

       (3) during any period of two consecutive calender years, the following
           individuals cease to constitute a majority of our directors then in
           office:

            (a) directors who constituted our board of directors at the
                beginning of the two-year period; together with

            (b) new directors whose election by our board of directors or whose
                nomination by stockholders was approved by at least a majority
                of the directors then still in office, which approving directors
                were directors:

              - at the beginning of the two-year period; or

              - whose election or nomination was previously approved by our
                board of directors; or

              - who were approved under the provisions of the investment
                agreement or the applicable certificate of designations;

       (4) Oxford consolidates or merges with or into another person, or any
           person consolidates or merges with or into Oxford, and immediately
           after the consolidation or merger, the persons who owned the
           outstanding voting securities of Oxford immediately before the
           consolidation or merger do not own, by reason of their prior
           ownership, a majority of the outstanding voting securities of Oxford
           or the surviving corporation; or

       (5) the adoption of a plan relating to the liquidation or dissolution of
           Oxford.


     The procedures for redemption are described below under "-- Redemption
Price and Procedures."



     We may redeem the offered preferred stock only out of funds at the time of
redemption legally available for the redemption of capital stock under the
Delaware General Corporation Law. In addition, we are subject to obligations and
various restrictive covenants that may limit our ability to redeem the offered
preferred stock upon a change of control. See "Description of Term Loan and
Senior Notes" beginning on page 62 of this prospectus. If we are required to
redeem offered preferred stock and we fail to pay the redemption price on the
redemption date, we will not be released from our obligation to pay the
redemption price, and dividends will accumulate on the missed payment.


REDEMPTION PRICE AND PROCEDURES

  REDEMPTION PRICE

     We will pay the redemption price of the offered preferred stock to be
redeemed in cash out of funds legally available for the payment of the
redemption price. The redemption price will be an amount per share equal to the
sum of:

     (1) the amount, if any, of all unpaid dividends accumulated on the offered
         preferred stock to be redeemed to the date of actual payment of the
         redemption price, whether or not these dividends have been declared;
         and

                                       19
<PAGE>   24


     (2) the stated value of the share of offered preferred stock to be
         redeemed, which is $1,000.


  OPTIONAL REDEMPTION AND MANDATORY REDEMPTION PROCEDURES


     If we redeem shares of offered preferred stock, we are required to send
notice of the redemption, including the redemption date, to the holders of
record of the offered preferred stock to be redeemed by first class mail,
postage prepaid, at each holder's address as it appears on our stock record
books. We are required to send the notice not more than 120 days nor fewer than
90 days before the date fixed for redemption. If we irrevocably deposit funds
sufficient to pay the aggregate redemption price for the series of offered
preferred stock to be redeemed, as described under "-- Deposit of Funds" on page
22 at the same time or prior to the delivery of a notice of redemption, then we
are required to send the notice of redemption not more than 120 days nor fewer
than 30 days before the fixed redemption date. However, if requested by TPG
Partners II or any of its affiliates, we must delay the fixed redemption date
for a period of no more than 30 days, if:


     - the notice of redemption is delivered less than 60 days before the
       redemption date; and


     - as of the date of the notice of redemption, TPG Partners II or any of its
       affiliates beneficially owns offered preferred stock of the series to be
       redeemed and has used its reasonable best efforts to complete a sale of
       some or all of its shares of the series of offered preferred stock to be
       redeemed prior to the stated redemption date but has not completed the
       sale.


We are required to notify the holders of the offered preferred stock to be
redeemed about this delay within five days of receiving the request from TPG
Partners II or its affiliates. We will not delay the redemption date in this
manner more than once.


     Our board of directors may fix a record date to determine the holders of
offered preferred stock to be redeemed. This record date will not be more than
30 days before the date that we mail the notice of redemption. On or after the
redemption date, each holder of the shares of offered preferred stock called for
redemption will be required to surrender the certificate evidencing those shares
to us at the place designated in the notice, and will be entitled to receive
payment of the redemption price when they surrender their certificate. No
dividends on the offered preferred stock called for redemption will accumulate
after the redemption date, and after that date, all rights of the holders of
shares of offered preferred stock that are redeemed will cease and terminate,
except to the extent we default in payment on the redemption date.


     As long as TPG Partners II or its affiliates hold any shares of a series of
the offered preferred stock, we may not deliver a notice of redemption with
respect to that series unless:


     - our preferred stock is rated Baa or better by Moody's Investors Service,
       Inc., or BBB or better by Standard & Poor's Ratings Group or, if our
       preferred stock is not rated by Moody's and Standard & Poor's, our
       unsecured debt is rated Baa or better by Moody's or BBB or better by
       Standard & Poor's; or


     - we have sufficient funds reasonably available under committed lines of
       credit or other similar sources of financing established with financially
       sound financing providers to pay, on the redemption date, the aggregate
       redemption price and have reserved funds or availability for payment of
       the total redemption price.

                                       20
<PAGE>   25


     We may deliver a notice of redemption without complying with these two
conditions if we irrevocably deposit funds sufficient to pay the total
redemption price for the offered preferred stock to be redeemed, as described
under "-- Deposit of Funds" on page 22, before or at the same time we deliver
the notice of redemption.


     Prior to any redemption date, other than in a mandatory redemption, we will
take all measures reasonably requested by TPG Partners II or its affiliates to
facilitate their sale or other disposition of the offered preferred stock to be
redeemed before the redemption date, including:

     - participation in due diligence sessions and provision of information
       about our management, business and financial condition;

     - preparation of offering memoranda, private placement memoranda and other
       similar documents; and

     - preparation and delivery of other certificates or documents that TPG
       Partners II or any of its affiliates reasonably requests.

  CHANGE OF CONTROL REDEMPTION PROCEDURES


     We are required to send notice of any change of control to the holders of
record of the outstanding shares of offered preferred stock not more than five
days following a change of control. This notice will describe the transaction
constituting the change of control and will set forth:


     - each holder's right to require us to redeem any or all shares of offered
       preferred stock held by him or her out of legally available funds;

     - the redemption date, which will not be more than 30 days from the date of
       the notice of the change of control; and


     - the procedures to be followed by holders in exercising his or her right
       to have his or her shares of offered preferred stock redeemed.



     If more than 50 holders or groups of affiliated holders own shares of a
series of offered preferred stock and if that series of offered preferred stock
is listed on any national securities exchange or quoted on any national
quotation system, we also are required to give notice of a change of control by
publication in a newspaper of general circulation in the Borough of Manhattan,
The City of New York, within 30 days following the change of control. Our
failure to give a notice of a change of control, or the formal insufficiency of
any notice, will not prejudice the rights of holders of offered preferred stock
to have us redeem their shares.



     If a holder of offered preferred stock elects to require us to redeem any
or all of its shares of offered preferred stock following a change of control,
the holder must deliver a written notice to us, in the form specified by us if
we did in fact give notice of a change of control as required, stating that the
holder wants us to redeem the shares it holds, and specifying the number of
shares to be redeemed. This notice must be delivered prior to the redemption
date set forth in the notice of a change of control, or, if the notice of a
change of control is not given, at any time following the last day we were
required to give the notice of a change of control. If we do not give the
required notice, the redemption date for any holder that elects to redeem shares
of offered preferred stock will be the date that is the later of (x) 30 days
following the last day we were required to give the notice of change of control
and (y) 15 days following the delivery of a notice of election by that holder.
If 50 or fewer holders or groups of affiliated holders own all of the shares of
a


                                       21
<PAGE>   26


series of the offered preferred stock, the holders or groups of holders of that
series may deliver a notice or an election to redeem at any time within 90 days
following the occurrence of a change of control without awaiting receipt of a
notice of a change of control or the expiration of the time allowed for the
delivery of a notice of a change of control. We will redeem the shares of
offered preferred stock so specified on the redemption date fixed by us or as
provided in the preceding sentence.


     We are required to comply with the requirements of Rules 13e-4 and 14e-1
under the Securities Exchange Act of 1934 and any other securities laws and
regulations to the extent such laws and regulations are applicable in connection
with the repurchase of the shares of the offered preferred stock as a result of
a change of control. To the extent that the provisions of any securities laws or
regulations conflict with the redemption procedures described above, we will
comply with the applicable securities laws and regulations and will not be
deemed to have breached our obligations to the holders of offered preferred
stock.

     On or prior to any redemption date, we are required to deposit with our
transfer agent or other redemption agent, as a trust fund for the benefit of the
holders of the shares of the offered preferred stock to be redeemed, an amount
of cash that is sufficient to redeem all offered preferred stock to be redeemed.
We also are required to provide irrevocable instructions and authority to the
transfer agent or other redemption agent to pay the redemption price to those
holders whose shares are to be redeemed. This deposit will constitute full
payment to the holders, and from and after the date of this deposit, all rights
of the holders with respect to the shares of the offered preferred stock that
are to be redeemed, except the right to receive the redemption price upon the
surrender of their respective certificates, will cease and terminate.


     Dividends will not accumulate on any shares of offered preferred stock
after the redemption date for those shares unless we fail to deposit cash
sufficient to redeem those shares. If the holders of any shares of offered
preferred stock to be redeemed do not claim the cash deposited for redemption
within two years after the deposit, the transfer agent or other redemption agent
will pay the balance to us. Upon this payment, the transfer agent or other
redemption agent will be relieved of all responsibility to holders and the sole
right of holders, with respect to shares to be redeemed, will be to receive the
redemption price as our general creditors. Any interest accrued on the deposited
funds will belong to us and will be paid to us from time to time on demand.

EXCHANGE


     We may exchange the Series D preferred stock for Series D Junior
Subordinated Debentures due May 13, 2008 and we may exchange the Series E
preferred stock for Series E Junior Subordinated Debentures due May 13, 2008 at
any time, in each case to the extent permitted by applicable law, in whole but
not in part. Each series of debentures will be issued pursuant to an indenture,
the form of which is attached as an exhibit to the registration statement of
which this prospectus is a part. We would issue a debenture in principal amount
of $1,000 in exchange for each share of the series of offered preferred stock
exchanged. The terms of the debentures are described under "Description of the
Debentures" beginning on page 28. The exchange may take place on any dividend
payment date at our offices or at any other place that our board of directors
designates.


                                       22
<PAGE>   27

     Unless we receive the prior written consent of the holders of all
outstanding shares of the series of offered preferred stock to be exchanged, we
may not exchange any shares if:


     (a) full cumulative dividends, to the extent payable or deemed payable
         through the date of exchange, have not been paid or set aside for
         payment on all outstanding shares of the series of offered preferred
         stock to be exchanged;



     (b) we have failed to amend our certificate of incorporation pursuant to
         Delaware law to give holders of the debentures the same power to vote
         that they had as holders of offered preferred stock; or


     (c) the exchange could result in any materially adverse tax consequence to
         TPG Partners II or any of its affiliates.


     In order to prevent an exchange of shares of offered preferred stock
because it could result in a material adverse tax consequence to TPG Partners II
or any of its affiliates, TPG Partners II or one of its affiliates must deliver
a written notice to us specifying in reasonable detail the nature of the tax
consequence, which must be a tax consequence other than the difference between
the tax treatment of distributions on the offered preferred stock and interest
payments on the debentures. TPG Partners II or one of its affiliates must
deliver that notice by the fifteenth day after it received the notice of
exchange. TPG Partners II and its affiliates have agreed not to deliver this
notice unless at the time TPG Partners II and its affiliates beneficially own a
total of at least 1,000 shares of the series of offered preferred stock to be
exchanged. If we receive an objection notice, then we will not exchange the
shares of offered preferred stock held by TPG Partners II and its affiliates,
and we will mail, within 15 days after receipt of the notice, written notice
that we are canceling the proposed exchange of shares of offered preferred stock
to each holder of record of shares of offered preferred stock to which we mailed
the notice of exchange.



     Before giving notice of our intention to exchange, we will execute and
deliver the indenture to a bank or trust company selected by our board of
directors and will qualify the trustee under the Trust Indenture Act of 1939.



     We are required to mail written notice of our intention to exchange the
offered preferred stock for debentures to each holder of record of shares of the
series of offered preferred stock to be exchanged not less than 90 days nor more
than 120 days prior to the date fixed for exchange.


     Prior to effecting any exchange, we are required to deliver to each holder
of shares of the series of offered preferred stock to be exchanged an opinion of
nationally recognized legal counsel which states that:


     (1) the applicable indenture and the debentures to be exchanged have been
         duly authorized and executed by Oxford and, when delivered by Oxford in
         exchange for shares of offered preferred stock, will constitute valid
         and legally binding obligations of Oxford enforceable against Oxford in
         accordance with their terms, subject to applicable bankruptcy,
         insolvency and similar laws affecting creditors' rights generally and
         to general principles of equity;



     (2) the exchange of debentures for the shares of offered preferred stock
         will not violate the provisions of the applicable certificate of
         designations that govern an exchange or of the Delaware General
         Corporation Law; and


     (3) the exchange of the debentures for the shares of offered preferred
         stock is exempt from the registration requirements of the Securities
         Act or, if no such exemption
                                       23
<PAGE>   28

         is available, that the debentures have been duly registered for
         exchange under the Securities Act.


     Upon the exchange of a series of offered preferred stock for debentures,
the rights of the holders of that series of offered preferred stock as our
stockholders will terminate, and the shares of offered preferred stock will no
longer be outstanding.


     Before any holder of offered preferred stock will be entitled to receive
debentures, a holder must surrender his or her certificates at our office or at
any other place that our board of directors may designate, and must state in
writing the name or names with addresses in which he or she wishes the
certificates for the debentures to be issued. After the surrender of
certificates, we will issue and deliver certificates for the debentures to the
holder, or to his or her nominee, at our office or other designated place. We
will exchange shares of offered preferred stock as of the close of business on
the date fixed for exchange as provided above, and the person entitled to
receive the debentures issuable upon exchange will be treated for all purposes,
including the accrual and payment of interest, as the record holder or holders
of debentures as of the close of business on that date.

VOTING RIGHTS


  RIGHTS OF TPG PARTNERS II AND ITS AFFILIATES



     Under the terms of the offered preferred stock, TPG Partners II and its
affiliates have certain voting rights as holders of shares of offered preferred
stock, which voting rights do not apply to other holders. In particular, only
TPG Partners II and its affiliates have the right to vote their shares of
offered preferred stock on all matters voted by holders of common stock. In
those circumstances, TPG Partners II and its affiliates vote together with the
holders of common stock as a single class. These voting rights are not
transferable to any subsequent holder of offered preferred stock. If the shares
of offered preferred stock are transferred to a person other than TPG Partners
II or its affiliates, and TPG Partners II or its affiliates subsequently
reacquire those shares, TPG Partners II and its affiliates would not reacquire
the right to vote those shares of offered preferred stock with holders of common
stock.


     Under the investment agreement, TPG Partners II and its affiliates are
permitted to designate members of our board of directors. The number of
directors TPG Partners II and its affiliates are permitted to designate at any
time is dependent on the number of shares of common stock issued or issuable
upon exercise of warrants held by TPG Partners II and its affiliates. In
addition to the other voting rights described in this section, if at any time
the number of directors on our board of directors designated by TPG Partners II
and its affiliates is less than the number they are entitled to designate under
the investment agreement, TPG Partners II and its affiliates, voting separately
as a single class, are entitled to elect a number of additional directors to our
board of directors equal to the deficiency. This right terminates at the time
the requisite number of directors on our board of directors are designated by
TPG Partners II and its affiliates.

  RIGHTS OF ALL HOLDERS


     All holders of shares of offered preferred stock, including TPG Partners II
and its affiliates, have the voting rights described below.


     If:

     (1) dividends payable on either series of offered preferred stock have been
         in arrears and not paid in full for four consecutive quarterly periods
         or if dividends on either

                                       24
<PAGE>   29

         series of offered preferred stock have been in arrears and not paid in
         full on May 13, 2000; or

     (2) we fail to satisfy our obligation to redeem shares of either series of
         offered preferred stock under the relevant certificate of designations,

then the number of directors constituting our board of directors automatically
will be increased by two, and the holders of a majority of the outstanding
shares of offered preferred stock will have the exclusive right, voting together
as a single class, to elect the two additional directors, except under the
circumstances described below.

     Under the investment agreement, TPG Partners II and its affiliates are
permitted to designate directors to our board of directors. However, TPG
Partners II and its affiliates are not permitted to elect and/or designate a
total of more than four directors to our board of directors. If at the time
holders of offered preferred stock have the right to elect additional directors,

     (1) TPG Partners II and its affiliates together beneficially own a majority
         of the outstanding shares of offered preferred stock; and

     (2) TPG Partners II and its affiliates are not permitted to elect one or
         both of the additional directors because of the restrictions described
         above,

then the holders of offered preferred stock, other than TPG Partners II and its
affiliates, will have the right to elect, voting together as a single class,
only one additional director.

     Any additional director will continue as a director, and these additional
voting rights will continue until:

     (1) we pay all dividends accumulated on the offered preferred stock in
         full; and

     (2) we satisfy any obligation to redeem the offered preferred stock that
         has become due, or we set aside all necessary funds for the redemption
         payment.

Upon the occurrence of these events, any additional director will cease to be a
director and the additional voting rights of the holders of offered preferred
stock will terminate subject to revesting if any subsequent failure to pay
dividends or redeem shares as described above occurs and subject to any rights
to elect directors of holders of any other series of our preferred stock.

     The holders of offered preferred stock may exercise their right to elect
additional directors at any annual meeting of stockholders, at a special meeting
of stockholders held for this purpose, or by the written consent of the holders
of the minimum number of shares required to take action. As long as this right
to vote continues, and unless this right has been exercised by written consent
of the minimum number of shares required to take action, the chairman of our
board of directors may call, and upon the written request of holders of record
of 20% of the outstanding shares of either the Series D preferred stock or the
Series E preferred stock, addressed to our secretary at our principal office,
will call a special meeting of the holders of shares entitled to vote as
described above. This meeting will be held within 60 days after delivery of a
request to the secretary, at the place and upon the notice provided by law and
in the by-laws for meetings of stockholders.

     Each director elected as described above will serve until the next annual
meeting or until his or her successor is elected and qualified, unless the
director's term of office has terminated as described above. If any vacancy
occurs among the directors elected as described above, the vacancy may be filled
for the unexpired portion of the term by the remaining director or directors
elected by the holders entitled to vote for directors as

                                       25
<PAGE>   30

described above, or their successor or successors in office, if any. If the
vacancy is not filled within 20 days after it is created or if all of the
remaining directors elected by the holders of offered preferred stock as
described in this section cease to serve as directors before their term expires,
the holders of the shares then outstanding and entitled to vote for the director
as described above may elect successors to hold office for the unexpired terms
of any vacant directorships. The holders of a majority of the shares entitled to
vote for directors as described above will have the right to remove with or
without cause at any time and replace any directors that they have elected, by
written consent or at a special meeting of the holders entitled to vote for
directors as described above.


     We may not take the following actions without the consent or affirmative
vote of the holders of at least a majority of the outstanding shares of a series
of offered preferred stock, voting separately as a class:


     - authorize, create or issue, or increase the authorized amount of any
       securities that rank senior or equal to the offered preferred stock for
       the purpose of receiving dividends or distributions upon the liquidation,
       dissolution or winding-up of Oxford;

     - authorize, create or issue, or increase the authorized amount of any
       class or series of capital stock or any security convertible into or
       exercisable for any class or series of capital stock, redeemable
       mandatorily or redeemable at the option of the holder at any time on or
       prior to May 13, 2008, whether or not redemption may occur only upon the
       occurrence of a specified event;


     - amend, alter or repeal any provision of our certificate of incorporation
       or our by-laws if the amendment, alteration or repeal alters or changes
       the powers, preferences or special rights of the applicable series of
       offered preferred stock so as to affect them materially and adversely; or


     - authorize or take any other action if such action alters or changes any
       of the rights of the applicable series of offered preferred stock in any
       respect or otherwise would be inconsistent with the provisions of the
       applicable certificate of designations and the holders of any class or
       series of our capital stock are entitled to vote on that action.

No consent or vote of the holders of the outstanding shares of offered preferred
stock is required:

     - for the creation or issuance by a trust formed at our direction of any
       series of preferred securities of such trust for financing purposes in an
       aggregate amount not to exceed $250,000,000; or

     - to authorize, create or issue, or increase the authorized amount of, any
       class or series of securities that rank junior to the offered preferred
       stock, or any security convertible into a stock of any class or series of
       securities that rank junior to the offered preferred stock, except to the
       extent such action would violate the relevant certificate of
       designations.


RESTRICTIONS ON DIVIDENDS


     As long as any shares of offered preferred stock are outstanding, our board
of directors:


     - may not declare, and we may not pay or set apart for payment, any
       dividend on any securities that rank junior to the offered preferred
       stock;


     - may not make any payment on account of, or set apart for payment money
       for a sinking or other similar fund for, the repurchase, redemption or
       other retirement of, any securities that rank junior or equal to the
       offered preferred stock or any

                                       26
<PAGE>   31

warrants, rights or options exercisable for or convertible into any securities
that rank junior or equal to the offered preferred stock, other than the
repurchase, redemption or other retirement of debentures or other debt
      securities that are convertible into or exchangeable for any securities
      that rank junior or equal to the offered preferred stock;

     - may not make any distribution in respect of the securities that rank
       junior to the offered preferred stock, either directly or indirectly, and
       whether in cash, obligations, shares or other property, other than
       distributions or dividends in securities that rank junior to the offered
       preferred stock to the holders of securities that rank junior to the
       offered preferred stock; and


     - may not permit any corporation or other entities directly or indirectly
       controlled by us to purchase or redeem any securities that rank junior or
       equal to the offered preferred stock or any warrants, rights, calls or
       options exercisable for or convertible into any securities that rank
       junior or equal to the offered preferred stock, other than the
       repurchase, redemption or other retirement of debentures or other debt
       securities that are convertible into or exchangeable for any securities
       that rank junior or equal to the offered preferred stock;


unless before or at the same time we take action, all accumulated and unpaid
dividends on shares of offered preferred stock not paid on the applicable dates,
including arrearages and accumulated dividends, have been paid.

     When dividends are not paid in full upon the offered preferred stock, all
dividends declared on the offered preferred stock and any other series of
securities that ranks equally with the offered preferred stock, with respect to
dividends, will be declared and paid pro rata so that the amount of dividends
declared and paid will bear to each other the same ratio that accumulated
dividends, including interest accrued in respect of such accumulated dividends,
on the shares of offered preferred stock and those other securities bear to each
other.

     The following actions are not prohibited by the restrictions described
above:

     (1) the acquisition, repurchase, exchange, conversion, redemption or other
         retirement for value of shares of offered preferred stock or any
         security that ranks equal to the offered preferred stock with respect
         to dividends or of any shares of preferred securities of a trust as
         referred to above; or

     (2) the acquisition, repurchase, exchange, conversion, redemption or other
         retirement for value by us of any securities that rank junior to the
         offered preferred stock with respect to dividends in accordance with
         any obligation in existence at the time of original issuance of the
         offered preferred stock.

NO INCONSISTENT OBLIGATIONS

     We are not permitted to enter into any agreement or issue any security that
prohibits, conflicts or is inconsistent with, or would be breached by, our
performance of our obligations with respect to the offered preferred stock.

USE OF THE OFFERED PREFERRED STOCK FOR EXERCISE OF WARRANTS


     Shares of offered preferred stock may be used as consideration for exercise
of the Series A warrants and the Series B warrants. For limitations on the
ability to use shares of offered preferred stock in this manner, see
"Description of the Warrants -- Limitations on Use of the Offered Preferred
Stock for Exercise of Warrants" beginning on page 45.


                                       27
<PAGE>   32


                         DESCRIPTION OF THE DEBENTURES



     We may exchange the shares of Series D preferred stock, in whole but not in
part, for Series D Junior Subordinated Debentures due May 13, 2008, and we may
exchange the shares of Series E preferred stock, in whole but not in part, for
Series E Junior Subordinated Debentures due May 13, 2008. We sometimes refer to
the Series D Junior Subordinated Debentures due May 13, 2008 as the "Series D
debentures," the Series E Junior Subordinated Debentures due May 13, 2008 as the
"Series E debentures" and, together, as the "debentures."



     We may exchange offered preferred stock for debentures only under certain
circumstances. For a description of these circumstances, see "Description of the
Offered Preferred Stock -- Exchange" beginning on page 22. We will not exchange
offered preferred stock for debentures before May 13, 2000.



     If we elect to exchange either series of preferred stock for debentures, we
will issue the debentures pursuant to an indenture to be entered into between
Oxford and a trustee to be selected by Oxford prior to such exchange, which
trustee would qualify at the time of such designation as a trustee under the
Trust Indenture Act of 1939. The following summarizes certain terms and
provisions of the Series D debentures and the Series E debentures. This summary
is not complete and is subject to, and qualified in its entirety by reference
to, applicable Delaware and New York law, the Trust Indenture Act of 1939 and
the provisions of our certificate of incorporation, our by-laws and the
indentures for each series of debentures. The form of indenture for each series
of debentures, which indentures are governed by the Trust Indenture Act of 1939,
and the debentures are exhibits to the registration statement of which this
prospectus is a part.



PRINCIPAL, MATURITY AND INTEREST



     Upon an exchange of a series of offered preferred stock for debentures, the
holders of the outstanding shares of the series of offered preferred stock to be
exchanged will be entitled to receive debentures with a principal amount equal
to $1,000 in exchange for each share of offered preferred stock exchanged.



     Each of the Series D debentures and the Series E debentures will mature on
May 13, 2008.



     We will be required to pay interest to holders of the Series D debentures
and Series E debentures in the following amounts and manner:

FORM OF DEBENTURES



     We expect to issue the debentures as one or more global debentures. The
Depository Trust Company is expected to be the depositary. See "Book-Entry;
Delivery and Form" beginning on page 42 for a description of the procedures of
the depositary.


                                       28
<PAGE>   33


REDEMPTION



  OPTIONAL REDEMPTION



     On and after May 13, 2003, we have the right to redeem all the outstanding
debentures of a series, in whole but not in part, at the price and in accordance
with the procedures described below.



  CHANGE OF CONTROL REDEMPTION



     If a "change of control" occurs, then holders of the debentures may require
us to redeem any or all of their debentures at the price and in accordance with
the procedures described below.



     We are subject to obligations and various restrictive covenants that may
limit our ability to redeem the debentures upon a change of control. These
factors are discussed in "Description of Term Loan and Senior Notes" beginning
on page 62 of this prospectus. If we are required to redeem debentures and we
fail to pay the redemption price on the redemption date, we will not be released
from our obligation to pay the redemption price, and interest will accrue on the
missed payment.



     For the definition of "change of control," see "Description of the Offered
Preferred Stock -- Change of Control Redemption" beginning on page 18.



  REDEMPTION PRICE



     Upon an optional redemption by us or a redemption upon a change of control,
we will pay the redemption price of the debentures to be redeemed in cash in an
amount per debenture equal to the sum of:



     (1) 100% of the principal amount of the debenture to be redeemed, plus



     (2) accrued and unpaid interest on the debenture to the redemption date.



  OPTIONAL REDEMPTION PROCEDURES



     If we redeem a series of debentures, we are required to send notice of the
redemption, including the redemption date, to the holders of record of the
debentures to be redeemed by first class mail, postage prepaid, at each holder's
address as it appears in the debenture register. We are required to send the
notice not more than 120 days nor fewer than 90 days before the date fixed for
redemption. If we irrevocably deposit funds sufficient to pay the aggregate
redemption price for the debentures to be redeemed, as described on page 31
under "-- Deposit of Funds," at the same time or prior to the delivery of a
notice of redemption, then we are required to send the notice of redemption not
more than 120 days nor fewer than 30 days before the fixed redemption date.
However, if requested by TPG Partners II or any of its affiliates, we must delay
the fixed redemption date for a period of no more than 30 days if:



     - the notice of redemption is delivered less than 60 days before the
       redemption date; and



     - as of the date of the notice of redemption, TPG Partners II or any of its
       affiliates beneficially owns debentures of the series to be redeemed and
       has used its reasonable best efforts to complete a sale of some or all of
       its debentures to be redeemed prior to the stated redemption date but has
       not completed the sale.


                                       29
<PAGE>   34


We are required to notify the holders of the debentures to be redeemed about
this delay within five days of receiving the request from TPG Partners II or its
affiliates. We may not delay the redemption date in this manner more than once.



     On or after the redemption date, each holder of the debentures called for
redemption will be required to surrender the debentures to us at the place
designated in the notice, and will be entitled to receive payment of the
redemption price when they surrender their debentures. From and after the
redemption date, all interest on debentures that have been redeemed will cease
to accrue and all rights of the holders as holders of debentures will cease and
terminate, except to the extent we default in a payment on the redemption date.



     As long as TPG Partners II or its affiliates hold debentures, we may not
deliver a notice of redemption with respect to that series of debentures unless:



     - our unsecured debt is rated Baa or better by Moody's Investors Service,
       Inc. or BBB or better by Standard & Poor's Ratings Group; or



     - we have sufficient funds reasonably available under committed lines of
       credit or other similar sources of financing established with financially
       sound financing providers to pay, on the redemption date, the aggregate
       redemption price, and we have reserved such funds or availability for the
       payment of the aggregate redemption price.



We may deliver a notice of redemption without complying with these two
conditions if we irrevocably deposit funds sufficient to pay the total
redemption price for the series of debentures to be redeemed, as described under
"-- Deposit of Funds" on page 31 before or at the same time we deliver the
notice of redemption.



     Prior to any redemption date, we will take all measures reasonably
requested by TPG Partners II to facilitate a sale or other disposition of the
debentures to be redeemed by TPG Partners II or its affiliates before the
redemption date, including, without limitation:



     - participation in due diligence sessions and provision of information
       about our management, business and financial condition;



     - preparation of offering memoranda, private placement memoranda and other
       similar documents; and



     - preparation and delivery of the other certificates or documents that TPG
       Partners II reasonably requests.



  CHANGE OF CONTROL REDEMPTION PROCEDURES



     We are required to send a notice of any change of control to the holders of
debentures to be redeemed not more than five days following a change of control.
This notice will describe the transaction constituting such change of control
and will set forth:



     - each holder's right to require us to redeem any or all debentures it
       holds or any portion thereof;



     - the redemption date, which will not be more than 30 days from the date of
       the notice of the change of control; and



     - the procedures to be followed by a holder in exercising its right to have
       its debentures redeemed.



     If more than 50 holders or groups of affiliated holders own debentures of a
series and if that series of debentures is listed on any national securities
exchange or quoted on any


                                       30
<PAGE>   35


national quotation system, we also are required to give notice of a change of
control by publication in a newspaper of general circulation in the Borough of
Manhattan, The City of New York, within 30 days following the change of control,
and to mail a similar notice to holders at the same time. Our failure to give a
notice of a change of control, or the formal insufficiency of any notice of a
change of control, will not prejudice the rights of holders of debentures to
cause us to redeem their debentures.



     If a holder of debentures elects to require us to redeem any or all of the
debentures it holds following a change of control, the holder must deliver a
written notice to us, in the form specified by us, if we did in fact give notice
of a change of control as required, stating that the holder wants us to redeem
the debentures it holds and specifying the debentures or portions of debentures
to be redeemed. This notice must be delivered prior to the redemption date set
forth in the notice of a change of control or, if the notice of a change of
control is not given as required, at any time following the last day we were
required to give the notice of a change of control. If we do not give the
required notice, the redemption date for any holder that elects to redeem
debentures will be the date that is the later of (x) 30 days following the last
day we were required to give the notice of change of control and (y) 15 days
following the delivery of a notice of election to require us to redeem the
debentures it holds by that holder. If 50 or fewer holders or groups of
affiliated holders own all of the debentures of a series, the holders or groups
of affiliated holders may deliver a notice of an election to redeem the
debentures it holds at any time within 90 days following the occurrence of a
change of control without awaiting receipt of a notice of a change of control or
the expiration of the time allowed for the delivery of a notice of a change of
control. We will redeem the debentures or portions of debentures on the
redemption date fixed by us or as provided in the preceding sentence.



     We are required to comply with the requirements of Rules 13e-4 and 14e-1
under the Securities Exchange Act of 1934 and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in
connection with the repurchase of the debentures as a result of a change of
control. To the extent that the provisions of any securities laws or regulations
conflict with the redemption procedures described above, we will comply with the
applicable securities laws and regulations and will not be deemed to have
breached our obligations to the holders of debentures.



  DEPOSIT OF FUNDS



     On or before the relevant redemption date, we are required to deposit with
the trustee or with a paying agent, which may be Oxford, as a trust fund for the
benefit of the holders of the debentures to be redeemed, an amount of cash that
is sufficient to pay the redemption price of all debentures to be redeemed. If
we or any of our subsidiaries or affiliates acts as paying agent, we will
segregate and hold in a separate trust fund for the benefit of the holders of
debentures all money held by us as paying agent. We also are required to provide
irrevocable instructions and authority to the trustee or the paying agent to pay
the redemption price to those holders whose debentures are to be redeemed upon
surrender of the debentures. This deposit will be deemed to constitute full
payment of the debentures to be redeemed, and from and after the date of the
deposit, all rights of the holders of debentures that are to be redeemed, except
the right to receive the redemption price upon the surrender of their respective
debentures, will cease and terminate.



     Interest will not accrue on any debentures to be redeemed after the
redemption date unless we fail to deposit cash sufficient to redeem those
debentures. If the holders of any debentures to be redeemed do not claim the
cash deposited for redemption within two


                                       31
<PAGE>   36


years after the deposit, the trustee or the paying agent will pay the balance so
deposited to us, or if held by us or any of our subsidiaries or affiliates, the
balance shall be discharged from the trust. Upon this payment, the trustee or
the paying agent will be relieved of all responsibility to holders, or if we or
any of our affiliates act as paying agent, we will be relieved of all
responsibility as trustee of the cash, and the sole right of holders of
debentures, with respect to debentures to be redeemed, will be to receive the
redemption price as our general creditors. Any interest accrued on the deposited
funds will belong to us and will be paid to us from time to time on demand.



RESTRICTIONS ON DIVIDENDS



     As long as any debentures are outstanding, we:



     - may not pay or set apart for payment any dividend on any Oxford capital
       stock;



     - may not make any payment on account of, or set apart for payment money
       for a sinking fund for, the repurchase, redemption or other retirement
       of, any Oxford capital stock or any warrants, rights or options
       exercisable for or convertible into any Oxford capital stock, other than
       the repurchase, redemption or other retirement of debentures or other
       debt securities that are convertible into or exchangeable for any Oxford
       capital stock;



     - may not make any distribution in respect of Oxford capital stock, either
       directly or indirectly, and whether in cash, obligations, shares or other
       property, other than distributions or dividends in capital stock to the
       holders of capital stock; and



     - may not permit any corporation or other entities directly or indirectly
       controlled by us to purchase or redeem any Oxford capital stock or any
       warrants, rights, calls or options exercisable for or convertible into
       any Oxford capital stock, other than the repurchase, redemption or other
       retirement of debt securities that are convertible into or exchangeable
       for any Oxford capital stock,



unless before or at the same time we take action, all interest that has become
due and payable on the debentures has been paid.



     The acquisition, repurchase, exchange, conversion, redemption or other
retirement for value by Oxford of a series of debentures in accordance with the
applicable indenture or of any shares of preferred securities of a trust as
referred to under "-- Voting Rights -- Rights of All Holders" beginning on page
36 is not prohibited by the restrictions described above.



EVENTS OF DEFAULT



     Set forth below are events of default with respect to debentures of either
series under the applicable indenture:



     (a) we do not pay the principal of any debenture of that series of
         debentures when due (upon maturity, required redemption or otherwise);



     (b) we fail to perform or we breach any other covenant or agreement under
         the applicable indenture or under the debentures of that series (other
         than referred to in (a) above) and such default or breach continues for
         60 days after we receive written notice of the default from the trustee
         or holders of at least 25% in aggregate principal amount of outstanding
         debentures of that series; or



     (c) certain events of bankruptcy, insolvency or reorganization affecting us
         occur.


                                       32
<PAGE>   37


     Within 30 days after the occurrence of a default or an event of default, we
will deliver to the trustee a written notice of a default or an event of default
referred to in (b) or (c) above, the status of the default or event of default
and what action we are taking or propose to take. The indentures require the
trustee to provide the holders of the debentures with notice of an event of
default within 30 days after it is known to the trustee or written notice of it
is received by the trustee, unless the event of default is cured or waived.
Except in the case of a default or event of default in payment of principal or
interest on any debenture, the trustee is not required to provide the holders of
debentures with notice of an event of default if the trustee determines in good
faith that withholding the notice is in the interests of the holders of the
debentures.



     If an event of default (other than an event of default described in clause
(c) above) occurs and is continuing with respect to the debentures of a series
outstanding, either the trustee by written notice to us, or the holders of at
least 25% in aggregate principal amount of the outstanding debentures of that
series by written notice to us and the trustee, may, and the trustee at the
request of the holders will, declare the principal of and accrued and unpaid
interest on all debentures of that series to be due and payable. However, the
holders of a majority in aggregate principal amount of outstanding debentures of
that series, by written notice to the trustee, may rescind and annul such
acceleration and its consequences if the recission would not conflict with any
judgment or decree and if all existing events of default, other than the
non-payment of accelerated principal or interest, have been cured or waived.



     If an event of default specified in clause (c) above occurs with respect to
the debentures of a series outstanding, the outstanding debentures of that
series will become immediately due and payable without any declaration or other
act on the part of the trustee or any holders.



     In general, subject to certain rights of the trustee, TPG Partners II and
its affiliates, so long as they own at least 20% of the aggregate principal
amount of outstanding debentures, or the holders of not less than a majority in
aggregate principal amount of the outstanding debentures of any series, by their
consent, may waive by written notice to the trustee an existing default or event
of default, except a default in the payment of principal or interest on any
debentures of that series. However, a waiver by TPG Partners II and its
affiliates of an existing default or event of default will not be effective if
holders of a majority of the aggregate principal amount of outstanding
debentures:



     (1) have delivered to us written notice of a default specified in clause
         (b) above;



     (2) have declared the principal of and accrued but unpaid interest on all
         debentures to be due and payable by virtue of the event of default; or



     (3) give written notice to the trustee that the holders do not consent to
         the waiver of the default or event of default and its consequences.



     Subject to the right of the trustee to be indemnified by holders of
debentures, the holders of a majority in aggregate principal amount of the
outstanding debentures of any series will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee or of exercising any trust or power conferred on the trustee with
respect to the debentures of that series.



     No holder of any debenture of a series will have the right to pursue any
remedy with respect to the indenture or debentures, unless:



     (1) the holder gives to the trustee written notice stating that an event of
         default with respect to the debentures of that series is continuing;


                                       33
<PAGE>   38


     (2) holders of at least 25% in aggregate principal amount of the
         outstanding debentures of that series, or TPG Partners II and its
         affiliates, so long as TPG Partners II and its affiliates own at least
         20% of the aggregate principal amount of outstanding debentures of that
         series, make a written request to the trustee to pursue the remedy;



     (3) such holder or holders offer to the trustee reasonable security or
         indemnity against any loss, liability or expense;



     (4) the trustee does not comply with the request within 60 days after
         receipt of the request and the offer of security or indemnity; and



     (5) the holders of a majority of the aggregate principal amount of
         outstanding debentures of that series, or TPG Partners II and its
         affiliates, so long as TPG Partners II and its affiliates own at least
         20% of the aggregate principal amount of outstanding debentures of that
         series, do not give the trustee a direction that, in the opinion of the
         trustee, is inconsistent with such request during the 60-day period.
         Any direction given by TPG Partners II and its affiliates will be
         disregarded, for purposes of this clause (5), if:



        (a) the request was made by holders of a majority of the aggregate
            principal amount of outstanding debentures; or



        (b) such holders give the trustee a direction that, in the opinion of
            the trustee, is inconsistent with such direction given by TPG
            Partners II and its affiliates.



However, such limitations may not impair or affect the right of a holder to
receive payment of principal of or interest on debentures held by such holder,
on or after the respective due dates (or, in the case of redemption, on the
redemption date) expressed in the debenture, or to bring suit for the
enforcement of any such payment, without the consent of the holder.



     We will be required to furnish to the trustee, within 90 days after the end
of each fiscal year, a statement as to the knowledge of any default or event of
default. If a default or event of default has occurred, we will describe the
default or event of default, the status of it and what action we are taking or
propose to take. We will furnish evidence to the trustee, as required by the
Trust Indenture Act of 1939, that we are in compliance with the indenture and
the debentures.



AMENDMENTS AND SUPPLEMENTS



     We may amend or supplement the indenture applicable to a series of
debentures with the written consent of the holders of a majority of the
aggregate principal amount of the outstanding debentures of that series.
However, no amendment or supplement may, without the consent of the holders of
each outstanding debenture of that series affected:



     (a) reduce the percentage in principal amount of the outstanding debentures
         of that series whose holders must consent to an amendment, supplement
         or waiver;



     (b) reduce the rate of or change or have the effect of changing the time
         for payment of interest on any debentures of that series;



     (c) reduce the principal of or change or have the effect of changing the
         fixed maturity of any debentures of that series, or change the date on
         which any such debentures may be subject to redemption, or reduce the
         redemption price therefor;


                                       34
<PAGE>   39


     (d) make any debentures of that series payable in money other than that
         stated in the debentures;



     (e) make any change in provisions of the applicable indenture entitling a
         holder to receive payment of principal and interest on such debentures
         on or after the due date or to bring suit to enforce such payment, or
         permitting the holders of a majority of the aggregate principal amount
         of outstanding debentures of that series to waive defaults or events of
         default; or



     (f) modify, in a manner that would adversely affect the interests of the
         holders of debentures of that series in any material respect, the
         obligations of Oxford to repurchase the debentures of that series upon
         a change of control.



     We may also amend the indenture applicable to a series of debentures
without notice to or the consent of any holder of debentures:



     (a) to cure any ambiguity or inconsistency;



     (b) to comply with the provisions of the applicable indenture in respect of
         the assumption by a successor of our obligations under the applicable
         indenture;



     (c) to provide for uncertificated debentures in addition to or in place of
         certificated debentures;



     (d) to add guarantees with respect to that series of debentures or to
         secure the debentures;



     (e) to add to our covenants in the indenture for the benefit of the holders
         of that series of debentures or to surrender any right or power
         conferred on us in the applicable indenture; or



     (f) to comply with any requirements of the Securities and Exchange
         Commission in connection with qualifying the applicable indenture under
         the Trust Indenture Act of 1939 or to provide for the succession of a
         successor trustee;



so long as any such change does not adversely affect the rights of any holder in
any material respect.



SATISFACTION AND DISCHARGE OF THE INDENTURE



     The indenture applicable to a series of debentures will be satisfied and
discharged and will cease to be of further effect as to all outstanding
debentures of that series, except as to surviving rights of registration of
transfer or exchange of that series of debentures and except as to compensation
and indemnity to the trustee under the applicable indenture, when:



     (a) either:



          (1) all debentures of that series (except lost, stolen or destroyed
              debentures which have been replaced or paid, and debentures for
              whose payment money has been deposited in trust or segregated and
              held in trust by us and thereafter repaid to us or discharged from
              such trust) have been delivered to the trustee for cancellation;
              or



          (2) all debentures of that series not delivered to the trustee for
              cancellation have become due and payable and we have irrevocably
              deposited or caused to be deposited with the trustee funds in an
              amount sufficient to pay and discharge the entire indebtedness on
              the debentures of that series not delivered to the


                                       35
<PAGE>   40


              trustee for cancellation, for principal and interest on the
              debentures of that series to the date of deposit together with
              irrevocable instructions from us directing the trustee to apply
              such funds to the payment thereof;



     (b) no default or event of default with respect to the applicable indenture
         or the debentures of that series has occurred and is continuing on the
         date of deposit or will occur as a result of the deposit and the
         deposit will not result in a breach or violation of, or constitute a
         default under, any other instrument to which we are a party or by which
         we are bound;



     (c) we have paid all other sums payable by us under the applicable
         indenture and the debentures of that series; and



     (d) we have delivered to the trustee an officer's certificate and an
         opinion of counsel as required by the applicable indenture.



VOTING RIGHTS



  RIGHTS OF TPG PARTNERS II AND ITS AFFILIATES



     Under the terms of the applicable indentures, TPG Partners II and its
affiliates have certain voting rights as holders of a series of debentures,
which voting rights do not apply to other holders. In particular, only TPG
Partners II and its affiliates have the right to vote their debentures of that
series on all matters voted on by holders of common stock. In those
circumstances, TPG Partners II and its affiliates vote together with the holders
of common stock (and any offered preferred stock entitled to vote) as a single
class. These voting rights:



     (1) apply to debentures issued to TPG Partners II or any of its affiliates
         in exchange for shares of a series of offered preferred stock that had
         similar voting rights; and



     (2) are not transferable to any subsequent holder of debentures.



If the debentures are transferred to a person other than TPG Partners II or its
affiliates, and TPG Partners II or its affiliates subsequently reacquire those
debentures, TPG Partners II or its affiliates would not reacquire the right to
vote those debentures with holders of common stock.



     Under the investment agreement, TPG Partners II and its affiliates are
permitted to designate members of our board of directors. See "Description of
the Offered Preferred Stock -- Voting Rights -- Rights of TPG Partners II and
Its Affiliates" on page 24 for a description of this right to designate
directors.



  RIGHTS OF ALL HOLDERS



     All holders of debentures, including TPG Partners II and its affiliates,
have the voting rights described below.



     If:



     (1) interest due and payable on either series of debentures has not been
         paid in full (or, if one series of offered preferred stock has not been
         exchanged for debentures, the dividends payable on that series of
         offered preferred stock have been in arrears and not paid in full) for
         four consecutive quarterly periods; or



     (2) we fail to satisfy our obligation to redeem or repay the principal of
         either series of debentures under the applicable indenture (or, if one
         series of offered preferred stock has not been exchanged for
         debentures, we have failed to satisfy our


                                       36
<PAGE>   41


         obligation to redeem shares of that series of offered preferred stock
         pursuant to its certificate of designations);



then the number of directors constituting our board of directors automatically
will be increased by two, and the holders of both series of debentures
representing at least a majority of the aggregate principal amount of
outstanding debentures will have the exclusive right, voting together as a
single class, to elect the two additional directors, except under the
circumstances described below. If the shares of one series of offered preferred
stock have not been exchanged for debentures, then the holders of the shares of
that series of offered preferred stock will vote together with the holders of
debentures as a single class, and, for the purposes of determining a majority of
the aggregate principal amount of debentures and the series of offered preferred
stock that was not exchanged, one share of the series of offered preferred stock
will be deemed to be equal to a principal amount of $1,000.



     Under the investment agreement, TPG Partners II and its affiliates are
permitted to designate directors to our board of directors. However, TPG
Partners II and its affiliates are not permitted to elect and/or designate a
total of more than four directors to our board of directors. If at the time
holders of debentures or, if applicable, the holders of shares of a series of
offered preferred stock that has not been exchanged for debentures, have the
right to elect additional directors:



     (1) TPG Partners II and its affiliates together beneficially own debentures
         representing a majority of the aggregate principal amount of
         outstanding debentures of both series (or, if the shares of one series
         of offered preferred stock have not been exchanged for debentures, TPG
         Partners II and its affiliates together beneficially own a majority of
         the aggregate principal amount of the debentures and that series of
         offered preferred stock), taken together as a single class; and



     (2) TPG Partners II and its affiliates are not permitted to elect one or
         both of the additional directors because of the restrictions described
         above;



then the holders of debentures (and, if applicable, holders of shares of a
series of offered preferred stock that has not been exchanged), other than TPG
Partners II and its affiliates, will have the right to elect, voting together as
a single class, only one additional director. For the purposes of determining a
majority of the aggregate principal amount of debentures and a series of offered
preferred stock, if necessary, one share of the series of offered preferred
stock that has not been exchanged will be deemed to be equal to a principal
amount of $1,000.



     Any additional director elected as described above will continue as a
director, and these additional voting rights will continue until:



     (1) we pay all interest due and payable on the debentures of each series
         and we pay in full all dividends accumulated on the series of offered
         preferred stock that has not been exchanged; and



     (2) we satisfy any obligation to redeem the debentures or the series of
         offered preferred stock that has not been exchanged or any obligation
         to repay the principal that has become due, or we set aside all
         necessary funds for the redemption payment.



Upon the occurrence of these events, any additional director will cease to be a
director and the additional voting rights of the holders of debentures will
terminate subject to revesting if any subsequent failure to pay interest or
dividends or redeem debentures or shares as


                                       37
<PAGE>   42


described above occurs and subject to any rights to elect directors of holders
of any other series of our preferred stock.



     The holders of debentures may exercise their right to elect additional
directors at any annual meeting of stockholders, at a special meeting held for
this purpose, or by the written consent of the holders of the minimum principal
amount of debentures required to take action. As long as this right to vote
continues, and unless this right has been exercised by written consent of the
minimum principal amount of debentures required to take action, the chairman of
our board of directors may call, and upon the written request of holders of
record of debentures representing 20% of the aggregate principal amount of the
outstanding debentures, addressed to our secretary at our principal office, will
call, a special meeting of the holders entitled to vote as described above. This
meeting will be held within 60 days after delivery of a request to the
secretary, at the place and upon the notice provided by law and in the by-laws
for meetings of stockholders.



     Each director elected as described above will serve until the next annual
meeting or until his or her successor is elected and qualified, unless the
director's term of office has terminated as described above. If any vacancy
occurs among the directors elected as described above, the vacancy may be filled
for the unexpired portion of the term by the remaining director or directors
elected by the holders of debentures (and, if applicable, holders of shares of a
series of offered preferred stock that has not been exchanged) entitled to vote
for directors as described above, or their successor or successors in office, if
any. If the vacancy is not filled within 20 days or if all of the remaining
directors elected as described in this section cease to serve as directors
before their term expires, the holders of debentures (and, if applicable,
holders of shares of a series of offered preferred stock that has not been
exchanged) entitled to vote for the director as described above may elect
successors to hold office for the unexpired terms of any vacant directorships by
written consent or at a special meeting. The holders of a majority of debentures
(and, if applicable, holders of shares of a series of offered preferred stock
that has not been exchanged) entitled to vote for directors as described above
will have the right to remove with or without cause at any time and replace any
directors that they have elected, by written consent or at a special meeting.



     We may not take the following actions without the consent or vote of the
holders of at least a majority of the aggregate principal amount of outstanding
debentures of a series, voting separately as a class:



     - authorize, create or issue, or increase the authorized amount of any
       class or series of capital stock or any security convertible into or
       exercisable for any class or series of capital stock, redeemable
       mandatorily or redeemable at the option of the holder of debentures of
       that series at any time on or prior to May 13, 2008, whether or not
       thereof only upon the occurrence of a specified event;



     - amend, alter or repeal any provision of our certificate of incorporation
       or our by-laws if the amendment, alteration or repeal alters or changes
       the rights of the holders of debentures of that series so as to affect
       them materially and adversely; or



     - authorize or take any other action if such action alters or changes any
       of the rights of holders of debentures of that series in any respect or
       otherwise would be inconsistent with the provisions of the applicable
       indenture and the holders of any class or series of our capital stock are
       entitled to vote on that action.



No consent or vote of the holders of debentures is required for the creation or
issuance by a trust formed at our direction of any series of preferred
securities of such trust for financing purposes in an aggregate amount not to
exceed $250,000,000.

SUBORDINATION



     The indebtedness evidenced by the debentures will be subordinated in right
of payment, as described below, to the prior payment in full of all "senior
indebtedness," as defined below. Each series of debentures will rank equally
with or will be senior to all other indebtedness of Oxford and will rank equally
with, and not senior to, each other. Accordingly, upon any payment or
distribution of assets to creditors upon a total or partial liquidation or a
total or partial dissolution of Oxford or in a winding up or bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to
Oxford or its property:



     (1) holders of senior indebtedness of Oxford will be entitled to receive
         payment in full of the senior indebtedness before holders of the
         debentures will be entitled to receive any payment of principal or
         interest on the debentures; and



     (2) until the senior indebtedness is paid in full, any distribution to
         which holders of debentures would be entitled will be made to holders
         of senior indebtedness as their interests may appear, except that
         holders of debentures may receive:



          (a) securities of a person that are subordinated to the senior
              indebtedness to at least the same extent as the debentures are
              subordinated to senior indebtedness and any indebtedness or
              securities issued in exchange for senior indebtedness, and



          (b) payments and other distributions made from any funds deposited by
              us pursuant to the applicable indenture.



     In addition, we may not pay the principal of or interest on a series of
debentures or make any deposit of money to satisfy and discharge our obligations
under the applicable indenture, and we may not repurchase, redeem or otherwise
retire any debentures of that series if:



     (1) any senior indebtedness is not paid when due; or



     (2) any other default on the senior indebtedness occurs and the maturity of
         the senior indebtedness is accelerated in accordance with its terms;



     unless, in either case:



          (a) the default has been cured or waived and such acceleration has
              been rescinded; or



          (b) such senior indebtedness has been paid in full.



     However, we may pay the debentures without regard to the above restrictions
if we and the trustee receive written notice approving the payment from the
representative of such senior indebtedness with respect to which either of the
events set forth in (1) or (2) above has occurred and is continuing.



     During the continuance of any default (other than a default described in
(1) or (2) above) with respect to any senior indebtedness pursuant to which the
maturity of the senior indebtedness may be accelerated immediately without
further notice (except a notice as may be required to effect such acceleration)
or the expiration of any applicable grace period, we may not pay the debentures
for a period, which we refer to as the "Payment Blockage Period," commencing
upon the receipt by the trustee (with a copy to us) of written notice, which we
refer to as a "Blockage Notice," of such default from the representative of the
holders of the senior indebtedness specifying an election to effect a


                                       39
<PAGE>   44


Payment Blockage Period and ending 179 days thereafter. A Payment Blockage
Period may end earlier than 179 days:



     (1) if written notice is given to the trustee and us from such person or
         persons who gave such Blockage Notice;



     (2) if the default giving rise to the Blockage Notice is no longer
         continuing; or



     (3) if the senior indebtedness has been repaid in full.



     Unless the holders of such senior indebtedness or their representative have
accelerated the maturity of such senior indebtedness, we may resume payments on
the debentures after such Payment Blockage Period.



     No more than one Payment Blockage Period may be commenced during any
360-day period. Also, no default or event of default with respect to the senior
indebtedness which existed or was continuing on the date of the commencement of
any Payment Blockage Period and which initiated such Payment Blockage Period may
be or may be made the basis of the commencement of a subsequent Payment Blockage
Period by the representative of the senior indebtedness (whether or not within a
period of 360 consecutive days), unless such default or event of default is
cured or waived for a period of not less than 90 consecutive days.



     By reason of this subordination, in the event of insolvency, our creditors
who are not holders of senior indebtedness or holders of debentures may recover
less, ratably, than holders of the senior indebtedness and may recover more,
ratably, than holders of debentures. A default under any senior indebtedness
would not constitute a default under the debentures unless payment of any amount
payable under the debentures is blocked by reason of such default.



     "Senior indebtedness," as used in this summary, means:



     (1) our outstanding 11% Senior Notes due 2005;



     (2) any indebtedness now or hereafter issued or incurred by us pursuant to
         the Term Loan Agreement, dated as of May 13, 1998, among Oxford, as
         borrower, the Lenders listed therein, as Lenders, DLJ Capital Funding,
         Inc., as Syndication Agent, and IBJ Schroeder Bank & Trust Company, as
         Facility Manager; and



     (3) any other indebtedness now or hereafter incurred by us, unless the
         instrument under which that indebtedness is incurred expressly provides
         that it is not superior in right of payment to the debentures of that
         series.



     Senior indebtedness does not include:



     (1) any liability for federal, state, local or other taxes owed or owing by
         us;



     (2) any indebtedness of us to any of our subsidiaries or other affiliates;



     (3) any trade payables; or



     (4) any debentures of either series.



     Senior indebtedness means, with respect to any guarantor, any guarantee by
the guarantor of senior indebtedness.



     As of the date of this prospectus, we had approximately $150 million
outstanding under the term loan agreement and $200 million aggregate principal
amount of 11% Senior Notes due 2005 outstanding.


                                       40
<PAGE>   45


     The indentures relating to each series of debentures will not contain
restrictions on our ability to incur additional indebtedness.



CERTAIN DEFINITIONS



     Set forth below are certain of the defined terms used in the indentures.
You should refer to the indentures for the definition of any other terms in this
prospectus for which no definition is provided.



     The term "affiliate" has the meaning set forth in Rule 12b-2 under the
Securities Exchange Act of 1934.



     The term "indebtedness" means, with respect to any person, whether recourse
is to all or a portion of the assets of such person, and whether or not
contingent, (i) any obligation of such person for money borrowed, (ii) any
obligation of such person evidenced by bonds, debentures, notes, guarantees or
other similar instruments, (iii) any reimbursement obligation of such person
with respect to letters of credit, bankers' acceptances or similar facilities
issued for the account of such person, (iv) any obligation of such person issued
or assumed as the deferred purchase price of property, assets or services (but
excluding trade accounts payable and other accrued liabilities arising in the
ordinary course of business), (v) any interest rate or currency swap or similar
hedging agreement and (vi) any capital lease obligation.



     The term "subsidiary" means, with respect to any person, (i) any
corporation, association or other business entity of which more than 50% of the
total voting power of shares of voting stock is at the time owned or controlled,
directly or indirectly, by such person or one or more of the other subsidiaries
of that person (or a combination thereof) and (ii) any partnership (A) the sole
general partner of the managing general partner of which is such person or a
subsidiary of such person or (B) the only general partners of which are such
person or of one or more subsidiaries of such person (or any combination
thereof).



NOTICES



     The trustee will cause all notices to the holders of the debentures to be
mailed by first class mail, postage prepaid, telecopier or overnight air
courier, to the address of each holder as it appears in the debenture register.
Any notice so mailed will be conclusively presumed to have been given to the
holders of the debentures.



GOVERNING LAW



     The indentures and the debentures will be governed by the laws of the State
of New York.



THE TRUSTEE



     Except during the continuance of an event of default, the trustee will
perform only such duties and responsibilities as are provided for by the Trust
Indenture Act of 1939 or specifically set forth in the applicable indenture. If
an event of default has occurred and is continuing, the trustee will exercise
the rights and powers vested in it under the applicable indenture and use the
same degree of care and skill as a prudent person would exercise or use under
the circumstances in the conduct of such person's own affairs. However, the
trustee will be under no obligation to exercise any of its rights and powers
under the


                                       41
<PAGE>   46


applicable indenture at the request or direction of holders of debentures unless
those holders offer the trustee reasonable indemnity or security against loss,
liability or expense.



     The applicable indenture and provisions of the Trust Indenture Act of 1939
incorporated by reference in the indenture limit the rights of the trustee,
should it become our creditor, to obtain payment of claims in certain cases or
to realize on certain property received by it in respect of any such claim as
security or otherwise. The trustee is permitted to engage in other transactions
with us or any affiliate. However, if it acquires any conflicting interest, as
defined in the Trust Indenture Act of 1939, it must eliminate the conflict or
resign.



                         BOOK-ENTRY; DELIVERY AND FORM



     The debentures initially will be represented by one or more debentures in
global form, which we refer to as "global debentures." It is expected that the
global debentures will be deposited upon issuance with The Depository Trust
Company, New York, New York, which we refer to as DTC, and registered in the
name of a nominee of DTC.



THE DEBENTURES



     We expect that pursuant to procedures established by DTC:



     (1) upon the issuance of the global debentures, DTC or its custodian will
         credit, on its internal system, the principal amount of the individual
         beneficial interests represented by the global debentures to the
         respective accounts of persons who have accounts with such depositary;
         and



     (2) ownership of beneficial interests in the global debentures will be
         shown on, and the transfer of ownership will be effected only through,
         records maintained by DTC or its nominee, with respect to interests of
         participants, and the records of participants, with respect to
         interests of persons other than participants.



Ownership of beneficial interests in the global debentures will be limited to
persons who have accounts with DTC or persons who hold interests through
participants.



     So long as DTC or its nominee is the registered owner or holder of the
global debentures, DTC or such nominee will be considered the sole owner or
holder of the debentures represented by the global debentures for all purposes
under the applicable indenture. No beneficial owner of an interest in the global
debentures will be able to transfer that interest except in accordance with
DTC's procedures.



     Payments of principal and interest due on the debentures will be made to
DTC or its nominee as the registered owner. None of Oxford, 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 debentures or for maintaining, supervising or reviewing
any records relating to this beneficial ownership interest.



     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest due on the debentures, will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the global debentures as shown on the records of DTC or its nominee. We also
expect that payments by participants to owners of beneficial interests in the
global debentures held through these participants will be governed by standing
instructions and customary practice, as is now the case with


                                       42
<PAGE>   47


securities held for the accounts of customers registered in the names of
nominees for those customers. These payments will be the responsibility of the
participants.



     Transfers between participants in DTC will be effected in the ordinary way
through DTC's settlement system in accordance with DTC rules and will be settled
in same day funds.



     DTC has advised us that it will take any action permitted to be taken by a
holder of debentures, including the representation of debentures for exchange as
described below, only at the direction of one or more participants to whose
account the DTC interests in the global debentures are credited. Further, DTC
will take action only as to such portion of the debentures as to which the
participant or participants have given such direction. However, if there is an
Event of Default under the applicable indenture, DTC will exchange the global
debentures for certificated debentures, which it will distribute to its
participants.



     DTC has advised us as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "Clearing Agency" registered pursuant to the provisions of
Section 17A of the Securities Exchange Act of 1934. DTC was created to hold
securities for its participants and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly.



     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the global debentures among participants of DTC, it is
under no obligation to perform those procedures, and those procedures may be
discontinued at any time. Neither we nor the trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.



CERTIFICATED SECURITIES



     No global debenture may be exchanged for a debenture registered, and no
transfer of a global debenture may be registered, unless:



     (1) the depositary (a) notifies us that it is unwilling or unable to
         continue as depositary for the global debenture or (b) has ceased to be
         a clearing agency registered under the Securities Exchange Act of 1934,
         and in either case we fail to appoint a successor depositary within 90
         days;



     (2) we, at our option, notify the trustee in writing that we elect to issue
         the debentures in certificated form; or



     (3) an event of default or any event which after notice or lapse of time or
         both would be an event of default with respect to the debentures has
         occurred and is continuing.



     In all cases, certificated debentures delivered in exchange for any global
debenture will be registered in the names as directed by the depositary. An
adjustment will be made


                                       43
<PAGE>   48


in the records of the registrar to reflect the decrease in the principal amount
of the relevant global debenture.



                          DESCRIPTION OF THE WARRANTS



     The following summarizes certain terms and provisions of the Series A
warrants and the Series B warrants. This summary is not complete and is subject
to, and qualified in its entirety by reference to, the warrant certificates,
applicable Delaware law, the provisions of our certificate of incorporation, our
by-laws and the form of warrant agreement pursuant to which the warrants are
issued. These documents are filed as exhibits to the registration statement of
which this prospectus is a part.


GENERAL


     The selling securityholders initially purchased the Series A warrants and
the Series B warrants in a private placement on May 13, 1998. As of the date of
this prospectus, 15,800,000 Series A warrants and 6,730,000 Series B warrants
were outstanding. The warrant agent for the Series A warrants and the Series B
warrants is ChaseMellon Shareholder Services, L.L.C.



     Any warrants sold by selling securityholders under this prospectus will be
covered by a warrant agreement between Oxford and ChaseMellon Shareholder
Services, L.L.C., as warrant agent. The warrant agent will act solely as an
agent of Oxford in connection with the warrants and will not assume any
obligation or relationship of agency or trust for or with any holder of warrants
or beneficial owners of warrants. A copy of the form of warrant agreement has
been filed as an exhibit to the registration statement of which this prospectus
is a part.


EXERCISE

     Each warrant entitles its holder to purchase one share of common stock at
an exercise price of $17.75 per share at any time until the expiration of the
warrants.

     The exercise price of the warrants was determined by negotiation between us
and TPG Partners II and its affiliates and should not be construed as an
estimate of the value of our common stock or to imply that the price of our
common stock will increase or decrease.


     We have reserved from our authorized but unissued shares a sufficient
number of shares of common stock for issuance upon the exercise of the warrants.


     The warrants provide for adjustment of their exercise price and for a
change in the number of shares that may be purchased upon exercise to protect
holders against dilution in the event of a stock dividend, stock split or
reverse split, upon issuance of shares of common stock at prices lower than the
market price of the common stock, upon distribution of a special dividend, or
upon a tender or exchange offer. The warrants also provide for adjustments to
the exercise price and number of shares that may be purchased upon exercise in
the event of a merger, consolidation, recapitalization or other transaction that
results in the conversion of our common stock into the right to receive other
securities, property or cash.

                                       44
<PAGE>   49

EXPIRATION OF WARRANTS

     The Series A warrants expire on the earlier of:

     - May 13, 2008; and

     - the redemption of all of the Series D preferred stock, which we can do
       only after May 13, 2003.


     The Series B warrants expire on the earlier of:


     - May 13, 2008; and

     - the redemption of all of the Series E preferred stock, which we can do
       only after May 13, 2003.

PROCEDURES FOR EXERCISE

     You may exercise a warrant by surrendering the warrant certificate on or
before its expiration date, with the form of "Election to Exercise" on the
reverse side of the warrant certificate completed and executed, accompanied by
payment of the full exercise price for the number of shares for which the
warrant is being exercised.

     You may make payment of the exercise price:

     - in cash;

     - by certified or official bank check;

     - by an exchange with us of a number of shares of offered preferred stock
       having a total stated value plus accumulated and unpaid dividends equal
       to the total exercise price (for limitations on the ability to use the
       offered preferred stock in this manner, see below under "-- Limitations
       on Use of the Offered Preferred Stock for Exercise of Warrants");


     - by an exchange with us of a principal amount of debentures having an
       aggregate principal amount plus accrued and unpaid interest equal to the
       total exercise price;



     - by an exchange with us of outstanding warrants, other than the warrants
       being exercised, having an aggregate value equal to the aggregate
       exercise price, which value per warrant will be determined by subtracting
       the exercise price of the warrant being exchanged from the average
       closing price of our common stock for the 10 trading days ending on the
       trading day before the day the exercise occurs; or


     - by any combination of the above.


     Upon the surrender of the warrant certificate and payment of the exercise
price, we will promptly issue and cause to be delivered the appropriate number
of shares of common stock to the holder, or to the persons designated by the
holder in writing. If you exercise fewer than all of the warrants represented by
a certificate, we will issue a new certificate for the remaining number of
warrants.


LIMITATIONS ON USE OF THE OFFERED PREFERRED STOCK FOR EXERCISE OF WARRANTS


     Holders of warrants may use shares of offered preferred stock as
consideration for the exercise of the warrants. However, before May 13, 2000,
holders of warrants may not use shares of Series D preferred stock as
consideration for the exercise of warrants unless they use a percentage of the
total number of shares of the Series D preferred stock issued by us


                                       45
<PAGE>   50

on February 13, 1999 that does not exceed the percentage of the total number of
shares of Series E preferred stock issued by us on February 13, 1999 that have
been:

     - redeemed by us;

     - repurchased by us as a result of a change of control or otherwise;

     - used as consideration in connection with the exercise of the warrants; or

     - otherwise retired by us.

NO FRACTIONAL SHARES


     We are not required to issue fractional shares of common stock. If any
fractional share would be issuable upon the exercise of a warrant, instead of
issuing the fractional share, we will pay the holder an amount in cash equal to
the market value of the fractional share.


NO RIGHTS AS A STOCKHOLDER

     Holders of warrants do not have rights as stockholders of Oxford. For
instance, they do not have the right to vote, to receive dividends or to receive
notices of stockholder meetings.

OTHER

     The holders of warrants have the opportunity to profit from a rise in the
market value of the common stock, with a resulting dilution in the interest of
all other stockholders. As a result, so long as the warrants are outstanding,
the terms on which we can obtain additional capital may be adversely affected.
We expect the holders of the warrants to exercise them at a time when we would,
in all likelihood, be able to obtain any needed capital by a new offering of
securities on terms more favorable than those provided for by the warrants.

                         REGISTRATION RIGHTS AGREEMENT


     The following summarizes certain provisions of the registration rights
agreement, dated as of February 23, 1998, between Oxford and TPG Partners II,
one of the selling securityholders. This summary is not complete and is subject
to, and qualified in its entirety by reference to, the registration rights
agreement, a copy of which is filed as an exhibit to the registration statement
of which this prospectus is a part.



     We are a party to a registration rights agreement with TPG Partners II, one
of the selling securityholders. Under the registration rights agreement, we have
agreed to use our reasonable best efforts to keep effective a shelf registration
statement at our expense, covering offers and sales of the offered preferred
stock, any debentures issued in exchange for the offered preferred stock, the
warrants and the common stock issuable upon exercise of the warrants. We
sometimes refer to the securities covered by the registration rights agreement
as the "registrable securities." We filed the shelf registration statement of
which this prospectus is a part with the SEC to comply with our obligations
under the registration rights agreement. Under the registration rights
agreement, we are required to keep the shelf registration statement effective
until 10 years after the date it is declared effective or, if earlier, the date
that all registrable securities have been sold under the shelf registration
statement or on which TPG Partners II and its affiliates are no longer entitled
to board representation under the investment agreement and are permitted to sell
their registrable securities without registration pursuant to Rule 144(k) under
the Securities Act.


                                       46
<PAGE>   51


     We will provide each holder of the registrable securities with copies of
this prospectus, notify each holder when the shelf registration statement has
been declared effective and take other actions described in the registration
rights agreement as are required to permit unrestricted sales of the registrable
securities. A holder that sells registrable securities under the shelf
registration statement is required to be named as a selling securityholder in
this prospectus and to deliver this prospectus to purchasers. Those holders also
will be subject to certain civil liability provisions under the Securities Act
in connection with these sales and are bound by the provisions of the
registration rights agreement, including certain indemnification obligations.



     If we file a registration statement under the Securities Act for an
underwritten offering of our securities for our own account or for the account
of holders, or if we offer securities convertible into or exchangeable for any
of our equity securities, the holders of registrable securities have agreed, if
requested, not to publicly sell or distribute any securities that are the same
as or similar to those being registered by us in connection with their sale, or
any securities convertible or exchangeable or exercisable for any such
securities, during the period beginning seven days before and ending no more
than 90 days after the effective date of the registration statement filed by us.



     We have agreed, in the case of an underwritten offering of registrable
securities, if requested, not to effect any public sale or distribution of any
securities the same as or similar to those registrable securities being sold in
the underwritten offering, or any securities convertible into or exchangeable or
exercisable for securities that are the same as or similar to those registrable
securities being sold, during the period beginning seven days before and ending
no more than 90 days after the date of the related underwriting agreement.



     Purchasers of the registrable securities offered by means of this
prospectus will not have any rights under the registration rights agreement.
Once sold under the registration statement, the registrable securities should be
freely tradeable except by purchasers that are our "affiliates" or are
"underwriters" of the registrable securities for purposes of the Securities Act.


                                       47
<PAGE>   52

                                USE OF PROCEEDS


     We will not receive any of the proceeds from any sale of the shares of
offered preferred stock, the debentures issuable in exchange for offered
preferred stock or the warrants. All of the proceeds from the sale will be
received by the selling securityholders. The proceeds from the original sale of
the warrants and the securities that were exchanged for the offered preferred
stock on May 13, 1998 were utilized, in part, to retire outstanding bridge
notes, to make capital contributions to regulated subsidiaries and to pay fees
and expenses approximating $39 million related to the sale of the warrants and
the securities that were exchanged for the offered preferred stock. We have used
and will use the balance for subsidiary capital contributions, as necessary, and
for general corporate purposes, or as otherwise described in a prospectus
supplement.



     We will receive proceeds upon exercise of the Series A warrants and the
Series B warrants. In the event that all of the outstanding Series A warrants to
purchase 15,800,000 shares of our common stock and outstanding Series B warrants
to purchase 6,730,000 shares of our common stock are exercised, we would receive
proceeds of approximately $399,907,500, excluding the expenses related to the
resale of the warrants under this prospectus. The exercise price of the Series A
warrants and the Series B warrants was determined by negotiation between us and
TPG Partners II and its affiliates based on the trading range of our common
stock during the negotiations.

             MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES


     The following describes the principal United States federal income tax
consequences of owning shares of offered preferred stock, warrants, shares of
common stock issuable upon exercise of the warrants, which we refer to as the
"warrant stock," and the junior subordinated debentures that you would receive
if we elected to exchange the offered preferred stock for debentures. It is the
opinion of Sullivan & Cromwell, our counsel. It applies to you only if you are
holding shares of offered preferred stock, warrants, shares of warrant stock and
the debentures as capital assets and you purchased shares of offered preferred
stock, warrants or shares of warrant stock in the offering at the offering
price. This discussion does not apply to you if you are a member of a class of
holders subject to special rules such as:


     - a dealer in securities or currencies,

     - a trader in securities that elects to mark to market,

     - a bank,

     - a tax-exempt organization,

     - a life insurance company,

     - a person that holds shares of offered preferred stock, warrants, shares
       of warrant stock or the debentures as a hedge, or is hedged, against
       currency or interest rate risks or that are part of a straddle or
       conversion transaction, or

     - a person whose functional currency is not the U.S. dollar.

This discussion is based on the Internal Revenue Code of 1986, its legislative
history, existing and proposed regulations thereunder, published rulings and
court decisions, all of which are subject to change, or changes in
interpretation, possibly with retroactive effect.


     When we refer to a "United States holder," we mean a beneficial owner of
shares of offered preferred stock, warrants, shares of warrant stock or
debentures that is:


     (1) a citizen or resident of the United States;

     (2) a corporation organized under the laws of the United States or any
         State;

     (3) an estate the income of which is subject to United States federal
         income taxation regardless of its source; or

     (4) a trust if a court within the United States is able to exercise primary
         supervision over the administration of the trust and one or more United
         States persons have the authority to control all substantial decisions
         of the trust.

     You are a "non-United States holder" if you are a beneficial owner of
shares of offered preferred stock, warrants, shares of warrant stock or
debentures and are not a United States holder.

PROSPECTIVE PURCHASERS OF SHARES OF OFFERED PREFERRED STOCK, WARRANTS, SHARES OF
WARRANT STOCK OR DEBENTURES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE
CONSEQUENCES, IN THEIR PARTICULAR CIRCUMSTANCES, UNDER THE INTERNAL REVENUE CODE
AND THE LAWS OF ANY OTHER TAXING JURISDICTION, OF THE OWNERSHIP OF SHARES OF
OFFERED PREFERRED STOCK, WARRANTS, SHARES OF WARRANT STOCK AND DEBENTURES.

TAXATION OF UNITED STATES HOLDERS

     This section describes the tax consequences to a United States holder. If
you are not a United States holder, this section does not apply to you.

  THE OFFERED PREFERRED STOCK

  Distributions on the Offered Preferred Stock -- General

     We do not have any accumulated earnings and profits as determined for
United States federal tax purposes, and there can be no assurance that we will
have earnings and profits in this or future tax years.

     If we do not have any current or accumulated earnings and profits, as
determined for United States federal income tax purposes, in a given tax year,
any distribution on the offered preferred stock, including any distributions of
additional shares of offered preferred stock, generally would not be subject to
United States federal income taxation if your tax basis in the offered preferred
stock is greater than or equal to the amount of the distribution. However, the
distribution would reduce your tax basis in the offered preferred stock, but not
below zero. If any portion of the distribution exceeds your tax basis in the
offered preferred stock, that portion would be subject to United States federal
income taxation as capital gain that is recognized in the taxable year in which
you received the distribution. Until we have earnings and profits, no
distribution is eligible for the 70% dividends-received deduction allowable to
corporations.

     If we have current or accumulated earnings and profits in a given tax year,
distributions on the offered preferred stock, including any distributions of
additional shares of offered preferred stock, would be taxable to you as
ordinary dividend income to the extent they are paid out of our current or
accumulated earnings and profits. Any portion of the distribution not paid out
of current or accumulated earnings and profits would be taxed as described in
the previous paragraph. Dividends would be eligible for the 70% dividends-
received deduction allowable to corporations, subject to the limitations
described below.

  Distributions on the Offered Preferred Stock -- The Offered Preferred Stock
"Paid in Kind"


     Until May 13, 2000, we may, at our option, pay dividends on the offered
preferred stock "in kind" through the issuance of additional offered preferred
stock. Dividends "paid in kind" will be treated as a distribution of an amount
equal to the fair market value of the additional offered preferred stock as of
the date of distribution, and will be taxed as described above under
"-- Distributions on the Offered Preferred Stock -- General." This amount will
also be the initial issue price and tax basis of the newly distributed offered
preferred stock for United States federal income tax purposes.


     If the redemption price of the offered preferred stock exceeds its offering
price, or the redemption price of the offered preferred stock issued as an
"in-kind" distribution exceeds its fair market value at the time the dividend is
"paid in kind," which we refer to, in either case, as a "redemption premium," by
one-fourth of one percent of the offered preferred stock's mandatory redemption
price multiplied by the number of complete years to its mandatory redemption,
you will be considered to have constructively received the entire amount of such
excess as a distribution over the period between issuance and redemption under a
constant yield method. If you purchased shares of offered preferred stock as a
unit together with the warrants, you must allocate your purchase price between
the offered preferred stock and the warrants based on their relative fair market
values to determine the offering price of the offered preferred stock. The
constant yield method would result in

                                       50
<PAGE>   55


increasing accruals of income over the term of the offered preferred stock under
rules similar to those for accruing original issue discount on the debentures,
as described under "-- Debentures -- Original Issue Discount" beginning on page
54. The constructive distribution would be a dividend in the year such
distribution is considered to be received to the extent of our current and
accumulated earnings and profits. Your tax basis in the offered preferred stock
would be increased by the amount of any redemption premium included in income.
In addition, each issuance of the offered preferred stock with more than a de
minimis redemption premium might not be fungible with the other offered
preferred stock, which might adversely affect the liquidity of the offered
preferred stock.


  Distributions on the Offered Preferred Stock -- Dividends-Received Deduction

     If we have current or accumulated earnings and profits, amounts treated as
dividends would be eligible for the 70% dividends-received deduction allowable
to corporations, subject to the limitations described below.


     If you are a corporation considering investing in the offered preferred
stock, you should consider the effect of:



     (1) Section 246A of the Internal Revenue Code which reduces the dividends-
         received deduction allowed to a corporate shareholder that has incurred
         indebtedness that is "directly attributable" to an investment in
         portfolio stock such as the offered preferred stock;



     (2) Section 246(c) of the Internal Revenue Code which, among other things,
         disallows the dividends-received deduction in respect of any dividend
         on a share of stock that is held for less than the minimum holding
         period (generally at least 46 days during the 90-day period beginning
         on the date which is 45 days before the date on which such share
         becomes ex-dividend with respect to such dividend); and



     (3) Section 1059 of the Internal Revenue Code which, under certain
         circumstances, reduces the basis of stock for purposes of calculating
         gain or loss in a subsequent disposition by the portion of any
         "extraordinary dividend" (as defined below) that is eligible for the
         dividends-received deduction.


     The President has currently proposed legislation that would eliminate the
70% dividends-received deduction for dividends on the offered preferred stock.
There can be no certainty whether, or in what form, such legislation will be
enacted or what its effective date would be.

  Distributions on the Offered Preferred Stock -- Extraordinary Dividends

     If you are a corporate United States holder, you are required to reduce
your tax basis, but not below zero, in the offered preferred stock by the
nontaxed portion of any "extraordinary dividend" if you did not hold the offered
preferred stock for more than two years before the earliest of the date the
dividend is declared, announced or agreed to. Generally, the nontaxed portion of
an extraordinary dividend is the amount excluded from income by operation of the
dividends-received deduction.

     An extraordinary dividend on the offered preferred stock generally would be
a dividend that:

     (1) equals or exceeds 5% of your adjusted tax basis in the offered
         preferred stock, treating all dividends having ex-dividend dates within
         an 85-day period as one dividend; or

     (2) exceeds 20% of your adjusted tax basis in the offered preferred stock,
         treating all dividends having ex-dividend dates within a 365-day period
         as one dividend.

                                       51
<PAGE>   56


     In determining whether a dividend paid on the offered preferred stock is an
extraordinary dividend, you may elect to substitute the fair market value of the
stock for your tax basis for purposes of applying these tests, provided that the
fair market value as of the day before the ex-dividend date is established to
the satisfaction of the Secretary of the Treasury. An extraordinary dividend
also includes any amount treated as a dividend in the case of a redemption that
is either non-pro rata as to all stockholders or in partial liquidation,
regardless of your holding period and regardless of the size of the dividend. If
any part of the nontaxed portion of an extraordinary dividend is not applied to
reduce your tax basis as a result of the limitation on reducing your basis below
zero, that part would be treated as capital gain and would be recognized in the
taxable year in which the extraordinary dividend is received. CORPORATE UNITED
STATES HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE
POSSIBLE APPLICATION OF SECTION 1059 TO THEIR OWNERSHIP OR DISPOSITION OF SHARES
OF OFFERED PREFERRED STOCK.


  Sale or Exchange of the Offered Preferred Stock Other Than by Redemption

     Upon the sale or other disposition of shares of offered preferred stock,
other than by redemption, you will generally recognize capital gain or loss
equal to the difference between the amount you realized upon the disposition and
your adjusted tax basis in the shares of offered preferred stock. This gain or
loss would be long-term capital gain or loss if at the time of sale, exchange or
other disposition you held the shares of offered preferred stock for more than
one year. Long-term capital gain of a non-corporate United States holder is
generally subject to a maximum tax rate of 20%. The deductibility of capital
losses is subject to limitations.

  Redemption of the Offered Preferred Stock

     A redemption of your shares of offered preferred stock generally would be a
taxable event and would be treated as if you sold the shares of offered
preferred stock if the redemption:

     (1) results in a "complete termination" of your stock interest;

     (2) is "substantially disproportionate"; or

     (3) is "not essentially equivalent to a dividend."

     In determining whether any of these tests has been met, you must take into
account the shares of offered preferred stock you actually own and the shares of
offered preferred stock you constructively own by reason of certain constructive
ownership rules set forth in Section 318 of the Internal Revenue Code.


     If your shares of offered preferred stock are redeemed in a redemption that
meets one of the tests described above, you generally would recognize taxable
gain or loss equal to the difference between the amount of cash and the fair
market value of property, other than our stock or stock of our successor, you
received and your tax basis in the shares of offered preferred stock redeemed.
See below under "-- Special Rules Regarding the Redemption of the Offered
Preferred Stock for Debentures" for a description of the rules applicable to a
redemption in which you receive debentures. This gain or loss would be long-term
capital gain or capital loss if you held the shares of offered preferred stock
for more than one year.


     If a redemption does not meet any of the tests described above, the cash
and the fair market value of property you receive generally would be taxed as a
dividend to the extent paid out of our current or accumulated earnings and
profits. Any amount in excess of our current or accumulated earnings and profits
would first reduce your tax basis in the shares

                                       52
<PAGE>   57

of offered preferred stock and thereafter would be treated as capital gain. If a
redemption of the offered preferred stock is treated as a distribution that is
taxable as a dividend, your basis in the redeemed shares of offered preferred
stock would be transferred to your remaining shares of offered preferred stock,
if any.


  Special Rules Regarding the Redemption of the Offered Preferred Stock for
Debentures


     Pursuant to the rules discussed above under "-- Redemption of the Offered
Preferred Stock," if we redeem the offered preferred stock for debentures, it
will be treated either as an exchange giving rise to capital gain or loss or as
a dividend. In the case of an exchange of the offered preferred stock for
debentures that would be treated as a redemption giving rise to capital gain or
loss, the amount realized on the exchange would be equal to the "issue price" of
the debentures plus any cash received on the exchange. The issue price of a
debenture will be:

     (1) its fair market value as of the exchange date if the debentures are
         traded on an established securities market at any time during the
         60-day period ending 30 days after the exchange date; or

     (2) the fair market value of the offered preferred stock as of the exchange
         date if such offered preferred stock is traded on an established
         securities market at any time during the 60-day period ending 30 days
         after the exchange date, but the debentures are not.

If neither the offered preferred stock nor the debentures are so traded, the
issue price of the debentures will be determined under Section 1274 of the
Internal Revenue Code, in which case the issue price will be the stated
principal amount of the debentures, provided that the yield on the debentures is
equal to or greater than the "applicable federal rate" in effect at the time the
debentures are issued. If the yield on the debentures is less than the
applicable federal rate, its issue price under Section 1274 of the Internal
Revenue Code will be equal to the present value as of the issue date of all
payments to be made on the debentures, discounted at the applicable federal
rate. It cannot be determined at the present time whether the offered preferred
stock or the debentures will, at the relevant time, be traded on an established
securities market within the meaning of the Treasury regulations or whether the
yield on the debentures will equal or exceed the applicable federal rate, as
discussed above.

     If a redemption of the offered preferred stock for cash or an exchange of
the offered preferred stock for debentures is treated as a dividend, you:

     (1) would not recognize any loss on the exchange;

     (2) (A) would recognize dividend income, rather than capital gain, in an
         amount equal to the fair market value of the debentures received
         without regard to your basis in the shares of offered preferred stock
         surrendered in the exchange, but only to the extent of its
         proportionate share of our current or accumulated earnings and profits
         and (B) would first reduce your tax basis in the shares of offered
         preferred stock and thereafter would recognize capital gain, to the
         extent that the distribution is not made out of our current or
         accumulated earnings or profits; and

     (3) the holding period for the debentures would begin on the day after the
         day on which you acquired the debentures.

                                       53
<PAGE>   58


YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO WHETHER IN LIGHT OF YOUR OWN
PARTICULAR CIRCUMSTANCES THE EXCHANGE WOULD BE TREATED AS A DIVIDEND OR AS A
SALE OR EXCHANGE. ADDITIONALLY, CORPORATE UNITED STATES HOLDERS SHOULD CONSULT
THEIR OWN TAX ADVISORS CONCERNING THE AVAILABILITY OF THE CORPORATE
DIVIDENDS-RECEIVED DEDUCTION AND THE POSSIBLE APPLICATION OF THE EXTRAORDINARY
DIVIDEND RULES OF SECTION 1059 OF THE INTERNAL REVENUE CODE TO AN EXCHANGE IF
THE DISTRIBUTION IS TAXABLE AS A DIVIDEND.



     Depending upon your particular circumstances, the tax consequences of
holding debentures may be less advantageous than the tax consequences of holding
shares of offered preferred stock because, for example, payments of interest on
the debentures would be taxable as ordinary income, regardless of whether we
have current or accumulated earnings and profits, while distributions on the
offered preferred stock would not be immediately subject to United States
federal taxation if we do not have current or accumulated earnings and profits
in a given year and such distribution does not reduce your basis in the shares
of offered preferred stock below zero, and because, as discussed below under
"-- Debentures -- Original Issue Discount," debentures may be issued with
greater amounts of OID than the Redemption Premium with respect to the offered
preferred stock.


  DEBENTURES


  Characterization of the Debentures



     Although not entirely free from doubt, the debentures should be treated as
debt for United States federal income tax purposes. The discussion in this
section assumes this treatment.


  Original Issue Discount


     Unless the debentures have a term of one year or less, the debentures would
be treated as issued at an original issue discount if the excess of the
debentures' "stated redemption price at maturity" over their issue price is more
than a "de minimis amount," as defined below. The manner in which the issue
price of the debentures would be determined is discussed under "-- The Offered
Preferred Stock -- Special Rules Regarding the Redemption of the Offered
Preferred Stock for Debentures." The stated redemption price at maturity of the
debentures is the total of all payments provided by the debentures other than
the stated interest payments.


     In general, if the excess of the debenture's stated redemption price at
maturity over its issue price is less than one-fourth of one percent of the
debenture's stated redemption price at maturity multiplied by the number of
complete years to its maturity (the "de minimis amount"), then such excess, if
any, constitutes "de minimis original issue discount" and the debenture is not
issued with original issue discount ("OID"). In general, the debentures would
have OID if:

     (1) the debentures are traded on an established securities market at any
         time during the 60-day period ending 30 days after the exchange date,
         and the fair market value of the securities is less than the stated
         redemption price at maturity by more than the applicable de minimis
         amount;

     (2) the offered preferred stock is traded on an established securities
         market at any time during the 60-day period ending 30 days after the
         exchange date, and the

                                       54
<PAGE>   59


         debentures are not, and the fair market value of the offered preferred
         stock is, less than the debentures' stated redemption price at maturity
         by more than the applicable de minimis amount; or



     (3) neither the debentures nor the offered preferred stock are traded on an
         established securities market at any time during the 60-day period
         ending 30 days after the exchange date, the yield on the debentures is
         less than the applicable federal rate by more than the applicable de
         minimis amount and the present value as of the issue date of all
         payments to be made on the debentures, discounted at the applicable
         federal rate, is less than the debentures' stated redemption price at
         maturity by more than the applicable de minimis amount.



Unless you elect to treat all interest as original issue discount as described
below under "-- Election to Treat All Interest as Original Issue Discount," you
must include the de minimis OID in income as stated principal payments on the
debentures are made.


     Generally, if your debenture matures more than one year from its date of
issue, you must include OID in income calculated on a constant-yield method
without regard to the receipt of cash attributable to such income, and generally
you will have to include in income increasingly greater amounts of OID over the
life of the debenture. The amount of OID includible in income is the sum of the
daily portions of OID with respect to the debenture for each day during the
taxable year or portion of the taxable year on which you hold the debenture,
which we refer to as "accrued OID." The daily portion is determined by
allocating to each day in any "accrual period" a pro rata portion of the OID
allocable to that accrual period. You may select an accrual period of any length
with respect to your debenture and you may vary the length of each accrual
period over the term of the debenture as long as:

     (1) no accrual period is longer than one year; and

     (2) each scheduled payment of interest or principal on the debenture occurs
         on either the final or first day of an accrual period.

The amount of OID allocable to an accrual period equals the excess of:

     (a) the product of the debenture's adjusted issue price at the beginning of
         the accrual period and the debenture's yield to maturity (determined on
         the basis of compounding at the close of each accrual period and
         properly adjusted for the length of the accrual period), over

     (b) the sum of the payments of qualified stated interest on the debenture
         allocable to the accrual period.

     The "adjusted issue price" of a debenture at the beginning of any accrual
period is the issue price of the debenture increased by:

     (x) the amount of accrued OID for each prior accrual period, and decreased
         by

     (y) the amount of any payments previously made on the debenture that were
         not qualified stated interest payments.

For purposes of determining the amount of OID allocable to an accrual period, if
an interval between payments of qualified stated interest on your debenture
contains more than one accrual period, the amount of qualified stated interest
payable at the end of the interval (including any qualified stated interest that
is payable on the first day of the accrual period immediately following the
interval) is allocated pro rata on the basis of relative lengths to each accrual
period in the interval, and the adjusted issue price at the

                                       55
<PAGE>   60

beginning of each accrual period in the interval must be increased by the amount
of any qualified stated interest that has accrued prior to the first day of the
accrual period but that is not payable until the end of the interval. The amount
of OID allocable to an initial short accrual period may be computed using any
reasonable method if all other accrual periods other than a final short accrual
period are of equal length. The amount of OID allocable to the final accrual
period is the difference between:

     (x) the amount payable at the maturity of the debenture (other than any
         payment of qualified stated interest), and

     (y) the debenture's adjusted issue price as of the beginning of the final
         accrual period.

  Election to Treat All Interest as Original Issue Discount


     You may elect to include in gross income all interest that accrues on your
debenture using the constant-yield method described above under the heading
"-- Original Issue Discount," with the modifications described below. For
purposes of this election, interest includes stated interest, OID, de minimis
original issue discount and unstated interest.


     If you make this election for your debenture, then, when you apply the
constant-yield method:


     - the issue price of the debenture would equal the issue price as
       determined under "-- The Offered Preferred Stock -- Special Rules
       Regarding the Redemption of the Offered Preferred Stock for Debentures"
       beginning on page 53,



     - the issue date of the debenture would be the exchange date, and



     - no payments on the debenture would be treated as payments of qualified
       stated interest.


This election would generally apply only to the debenture with respect to which
it is made and may not be revoked without the consent of the Internal Revenue
Service.


     Pursuant to section 163 of the Internal Revenue Code, the "disqualified
portion" of the OID accruing on certain debt instruments may be treated as a
dividend eligible for the dividends-received deduction. The corporation issuing
such debt instruments is not allowed to deduct the "disqualified portion" of the
OID accruing on the debt instrument and is allowed to deduct the remainder of
the OID only when paid.



     This treatment will apply to "applicable high yield discount obligations,"
or "AHYDOs", which, generally, are debt instruments that have a term of more
than five years, have a yield to maturity that equals or exceeds five percentage
points above the "applicable federal rate" and have "significant" OID. A debt
instrument is treated as having "significant" OID if the aggregate amount that
would be includible in gross income with respect to such debt instrument for
periods before the close of any accrual period ending five years or more after
the date of issue exceeds the sum of:


     (1) the aggregate amount of interest to be paid in cash under the debt
         instrument before the close of such accrual period, and

     (2) the product of the initial issue price of such debt instrument and its
         yield to maturity.

                                       56
<PAGE>   61

For purposes of determining whether a debenture is an AHYDO, holders are bound
by the issuer's determination of the appropriate accrual period. It is
impossible to determine at the present time whether a debenture will be treated
as an AHYDO.


     If a debenture is treated as an AHYDO, a corporate United States holder
would be treated as receiving dividend income, to the extent of our current and
accumulated earnings and profits, solely for purposes of the dividends-received
deduction, in an amount equal to the "dividend equivalent portion" of the
"disqualified portion" of the OID. The "disqualified portion" of the OID is
equal to the lesser of:


     (1) the amount of OID, or


     (2) the portion of the "total return," that is, the excess of all payments
         to be made with respect to such obligation over its issue price, on the
         obligation that bears the same ratio to the obligation's total return
         as the "disqualified yield," that is, the extent to which the yield
         exceeds the applicable federal rate plus 6%, bears to the obligation's
         yield to maturity.


The dividend equivalent portion of the disqualified portion is the amount that
would have been treated as a dividend if we had distributed it with respect to
our stock. Our deduction for OID will be substantially deferred with respect to
a debenture that is treated as an AHYDO. In addition, such deduction will be
disallowed if and to the extent that the yield on such AHYDO exceeds the
applicable federal rate by more than 6%.

  Purchase, Sale, Retirement and Other Disposition of the Debentures

     Your adjusted tax basis in the debentures you receive in exchange for
shares of offered preferred stock will, in general, be equal to the initial tax
basis of such debentures, that is, the issue price of the debentures, if the
exchange is treated as a redemption giving rise to capital gain or the fair
market value of the debentures on the exchange date, if the exchange is treated
as a dividend, increased by OID you previously included in your income. Upon the
sale, exchange or retirement of a debenture, you will generally recognize
capital gain or loss equal to the difference between the amount realized, not
including any amounts attributable to accrued and unpaid interest, and your tax
basis in the debenture.

  Ownership and Disposition of Warrants

     The warrants may be sold individually or as a unit. Each unit is comprised
of one or more shares of offered preferred stock and one or more warrants. If
you purchase a unit you must allocate your purchase price between the offered
preferred stock and the warrants based on their relative fair market values to
determine your tax basis in the shares of offered preferred stock and the
warrants and the amount of redemption premium, if any, on the offered preferred
stock. If the warrant is sold individually, your tax basis in a warrant will be
its purchase price.

  Sale of a Warrant

     Generally, you will recognize gain or loss upon the sale of a warrant in an
amount equal to the difference between the amount realized on the sale and your
adjusted tax basis in the warrant. Your adjusted tax basis in a warrant
purchased in the offering as a unit will be the portion of the initial offering
price allocable to a warrant, adjusted as described below under "-- Adjustments
Under the Warrants." Gain or loss attributable to the sale of the warrants will
constitute capital gain or loss if you would have held the

                                       57
<PAGE>   62

warrant stock as a capital asset and will be long-term capital gain or loss if
you held the warrants for more than one year.


  Exercise of a Warrant, Disposition of Common Shares and Dividends


     In general, you will not recognize gain or loss upon the exercise of a
warrant, except with respect to cash, if any, paid in lieu of the issuance of
fractional shares. Upon exercise of a warrant with cash, your tax basis in the
shares of warrant stock acquired will be the sum of:

     (a) your adjusted tax basis in the warrant, and

     (b) the cash paid upon exercise of the warrant.

     If you receive any cash in lieu of fractional shares of warrant stock, you
will recognize gain or loss, and the character and amount of gain or loss will
be determined as if you had received such fractional shares and then immediately
sold them for cash. Your holding period of the stock acquired upon exercise of a
warrant begins on the day following the day of exercise.

  Expiration of the Warrants

     Upon the expiration of an unexercised warrant, you will recognize a loss
equal to your adjusted tax basis of the warrant. A loss realized upon expiration
of the warrant will be capital loss if you would have held the warrant stock as
a capital asset and will be long-term capital loss if you held the warrant for
more than one year.

  Adjustments Under the Warrants

     Pursuant to the terms of the warrants, the number of shares of warrant
stock you may purchase upon exercise of the warrants is subject to adjustment
from time to time upon the occurrence of certain events. In certain
circumstances, a change in conversion ratio or any transaction having a similar
effect may be treated as a distribution if your proportionate interest in the
earnings and profits of the issuer is increased by such change or transaction.
Thus, under certain future circumstances which may or may not occur, an
adjustment pursuant to the terms of the warrants may be treated as a taxable
distribution to the extent of our current or accumulated earnings and profits,
without regard to whether you receive any cash or other property. If you receive
such a taxable distribution, your tax basis in the warrants will be increased by
an amount equal to the taxable distribution.

WARRANT STOCK

     Any distributions you receive on the warrant stock will be taxable as
ordinary income to the extent of our current and accumulated earnings and
profits. If we do not have current or accumulated earnings or profits, the
payment will first offset your basis in the warrant stock and any amount that
exceeds your basis will be treated as capital gain. Any gain or loss upon the
sale or exchange of shares of warrant stock will be capital gain or loss, and
will be long-term capital gain or loss if you owned the shares of warrant stock
for more than one year.

TAXATION OF NON-UNITED STATES HOLDERS

     This section describes the tax consequences to non-United States holders.
If you are a United States holder, this section does not apply to you.

                                       58

  INTEREST PAYMENTS

     Under present United States federal income tax law, and subject to the
discussion of backup withholding below, if you are the beneficial owner of a
debenture and we or our paying agents make payments to you of principal,
premium, if any, and interest, including OID, you will not be subject to United
States federal withholding tax if, in the case of interest or OID:

     (a) you do not actually or constructively own 10% or more of the total
         combined voting power of all classes of our stock entitled to vote;

     (b) you are not a controlled foreign corporation that is related to us
         through stock ownership; and

     (c) either:

         (1) you certify to us or our agent, under penalties of perjury, that
             you are not a United States holder and provide your name and
             address; or

         (2) a securities clearing organization, bank or other financial
             institution that holds customers' securities in the ordinary course
             of its trade or business (a "financial institution") and holds the
             debenture certifies to us or our agent under penalties of perjury
             that it, or a financial institution between it and you, has
             received such statement from you and furnishes the payor with a
             copy thereof.

Recently finalized United States Treasury Regulations, which we refer to as the
"Final Withholding Regulations," would provide for alternative methods for
satisfying the certification requirement. The Final Withholding Regulations also
would require, in the case of debentures held by a foreign partnership, that:

     (1) the certification be provided by the partners rather than by the
         partnership; and


     (2) the partnership provide certain information.


A look-through rule would apply in the case of tiered partnerships. The Final
Regulations are effective for payments made after December 31, 2000.

  DIVIDEND INCOME

     Dividends paid to you will be subject to withholding of United States
federal income tax at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty, unless the dividends are "effectively connected"
with your conduct of a trade or business within the United States, and they are
attributable to your United States permanent establishment, if an applicable
income tax treaty so requires as a condition for subjecting you to United States
income tax on a net income basis. Such "effectively connected" dividends,
generally, are not subject to withholding tax if you satisfy certain
certification requirements. Instead, "effectively connected" dividends are taxed
at rates applicable to United States citizens, resident aliens and domestic
United States corporations. In addition, if you are a non-United States
corporation, you may, under certain circumstances, be subject to an additional
"branch profits tax" on "effectively connected" dividends at a 30% rate or at a
lower rate if you are eligible for the benefits of an applicable income tax
treaty.

     Under current United States Treasury Regulations, dividends paid to an
address in a foreign country are presumed to be paid to a resident of that
country, unless the payor has knowledge to the contrary, for purposes of the 30%
withholding discussed above. Under

                                       59
<PAGE>   64

current interpretations of United States Treasury Regulations, this presumption
also applies for purposes of determining whether a lower withholding rate
applies under an income tax treaty.


     Under the Final Withholding Regulations, you must satisfy certain
certification requirements in order to claim the benefit of a lower treaty rate.
See "-- Taxation of Non-United States Holders -- Interest Payments" on page 59.


     If you are eligible for a reduced rate of United States withholding tax
under a tax treaty, you may obtain a refund of any amount withheld in excess of
that rate by filing a refund claim with the United States Internal Revenue
Service.

  SALE OR DISPOSITION

     You will not be subject to United States federal income tax in respect of a
sale or disposition of shares of offered preferred stock or shares of warrant
stock, or, to the extent of your basis in the shares of offered preferred stock
or shares of warrant stock, on distributions paid on the offered preferred stock
or warrant stock if we do not have current or accumulated earnings and profits,
warrants or debentures unless:


     (1) the gain is effectively connected with your trade or business in the
         United States and is attributable to your permanent establishment
         maintained in the United States, if an applicable income tax treaty so
         requires as a condition for you to be subject to United States taxation
         on a net income basis in respect of capital gain;


     (2) if you are an individual, you are present in the United States for 183
         or more days in the taxable year of the sale and certain other
         conditions apply; or

     (3) we are or have been a "United States real property holding corporation"
         for federal income tax purposes.

We have not been, are not and do not anticipate becoming a "United States real
property holding corporation" for federal income tax purposes. If you are a
corporation, your "effectively connected" gains may also, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate or
such lower rate as may be specified by an applicable income tax treaty.

ESTATE TAXES

     If you are an individual who at death is not a citizen or resident of the
United States, your debenture will not be includible in your gross estate for
purposes of the United States federal estate tax as a result of your death if:

     (a) you did not actually or constructively own 10% or more of the total
         combined voting power of all classes of our stock entitled to vote; and

     (b) the income on the debenture would not have been effectively connected
         with your United States trade or business at your death.

     If you are a non-United States holder of shares of offered preferred stock,
warrants or shares of warrant stock at the time of your death, they will be
included in your gross estate for United States federal estate tax purposes,
unless an applicable estate tax treaty provides otherwise.

BACKUP WITHHOLDING AND INFORMATION REPORTING

  UNITED STATES HOLDERS


     In general, if you are a United States holder, other than certain exempt
recipients, such as corporations, information reporting requirements will apply
to dividends paid in respect of your shares of offered preferred stock and
warrant stock, including the accrual of the redemption premium, to principal and
interest paid in respect of your debentures, and to the proceeds received on the
sale, exchange or redemption of your shares of offered preferred stock,
debentures, warrants or warrant stock, and "backup withholding" at a rate of 31%
will apply to the payments if you fail to provide an accurate taxpayer
identification number or you are notified by the Internal Revenue Service that
you have failed to report all interest and dividends required to be shown on
your federal income tax returns. You should consult your own tax advisor
concerning the application of information reporting and backup withholding to
the preferred stock, debentures, warrants or warrant stock.


     Any amounts withheld under the backup withholding rules will be allowed as
a refund or a credit against your United States federal income tax liability
provided the required information is furnished to the IRS.

  NON-UNITED STATES HOLDERS


     Under current law, if you are a non-United States holder of a debenture,
information reporting on Internal Revenue Service Form 1099 and backup
withholding will not apply to payments of principal, premium, if any, and
interest, including OID, made by us or a paying agent; provided, that you
certify to us or our agent, under penalties of perjury, that you are not a
United States holder and provide your name and address, or a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "financial
institution") and holds the debenture, certifies to us or our agent, under
penalties of perjury, that such statement has been received from you or by a
financial institution between it and you and furnishes as the payor with a copy
thereof; and provided further that the payor does not have actual knowledge that
you are a United States person. We or a paying agent, however, may report, on
Internal Revenue Service Form 1042-S, payments of interest, including OID, on
the debentures. See "-- Taxation of Non-United States Holders -- Interest
Payments" on page 59 with respect to the rules under the Final Withholding
Regulations.


     In general, if you are a non-United States holder, dividends paid to you
are not subject to United States information reporting requirements and backup
withholding tax if you are either subject to the 30% withholding tax, discussed
above, or are not subject to the 30% withholding tax because you are eligible
for the benefits of an income tax treaty. However, dividend payments will be
reported for purposes of the 30% withholding tax discussed above. If you do not
meet any of the requirements listed above to exempt you from backup withholding
tax and fail to provide certain information, including a United States taxpayer
identification number, or otherwise establish a status as an "exempt recipient,"
you may be subject to backup withholding of United States federal income tax at
a rate of 31% on dividends paid.

     Under current law, dividends paid to an address in a foreign country are
generally treated as exempt from backup withholding and information reporting
unless the person making the payment has definite knowledge that the recipient
is a United States person. However, under the Final Withholding Regulations
discussed above, dividend payments generally will be subject to information
reporting and backup withholding unless certain certification requirements are
met.

                                       61
<PAGE>   66

     In general, United States information reporting and backup withholding
requirements also will not apply to a payment made outside the United States of
the proceeds of a sale of shares of offered preferred stock or warrant stock
through an office outside the United States of a non-United States broker.
However, United States information reporting, but not backup withholding,
requirements will apply to a payment made outside the United States of the
proceeds of a sale of shares of offered preferred stock or warrant stock through
an office outside the United States of a broker:

     (1) that is a United States person;

     (2) that derives 50% or more of its gross income for certain periods from
         the conduct of a trade or business in the United States;

     (3) that is a "controlled foreign corporation" as to the United States; or

     (4) with respect to payments made after December 31, 2000, that is a
         foreign partnership, if at any time during its tax year, one or more of
         its partners are U.S. persons, as defined in U.S. Treasury regulations,
         who in the aggregate hold more than 50% of the income or capital
         interest in the partnership or if, at any time during its tax year, the
         foreign partnership is engaged in a United States trade or business,

unless the broker has documentary evidence in its records that the holder or
beneficial owner is a non-United States person or the holder or beneficial owner
otherwise establishes an exemption.

Payment of the proceeds of the sale of shares of offered preferred stock and
shares of warrant stock to or through a United States office of a broker is
currently subject to both United States backup withholding and information
reporting unless the holder certifies its non-United States status under
penalties of perjury or otherwise establishes an exemption.


     A non-United States holder generally may obtain a refund of any excess
amounts withheld under the backup withholding rules by filing the appropriate
claim for refund with the United States Internal Revenue Service.



                   DESCRIPTION OF TERM LOAN AND SENIOR NOTES



     The following summarizes the principal terms and conditions of the term
loan agreement and the indenture relating to our 11% Senior Notes due 2005. The
description below does not purport to be complete and is qualified in its
entirety by reference to the term loan agreement and the indenture relating to
the senior notes.



THE TERM LOAN



     The term loan agreement, dated as of May 13, 1998, by and among the
financial institutions listed in the term loan agreement, as lenders, DLJ
Capital Funding, Inc., as syndication agent, and IBJ Schroeder Bank & Trust
Company, as facility manager, provides for a $150 million senior secured term
loan with a final maturity on May 13, 2003, at which time all outstanding
amounts will be due and payable. We currently have borrowed $150 million under
the term loan. Prior to the final maturity of the term loan, there are no
scheduled principal payments. The term loan agreement provides for mandatory
prepayments of:



     (1) all net proceeds from the sale of assets, subject to certain
         exceptions, and to the receipt of any required regulatory approvals;


                                       62
<PAGE>   67


     (2) all net proceeds from the issuance of debt securities;



     (3) 50% of the net proceeds from certain equity issuances; and



     (4) the entire aggregate principal amount plus a premium equal to 1.00% of
         the aggregate principal amount of the loan prepaid upon a "change of
         control" as that term is defined in the term loan agreement.



     The term loan bears interest at a rate per annum equal to the
administrative agent's reserve-adjusted LIBOR rate plus 4.25%.



THE SENIOR NOTES



     We issued the 11% Senior Notes due 2005, which we refer to as the "senior
notes," under an indenture, dated as of May 13, 1998, between us and The Chase
Manhattan Bank, as trustee. We refer to this indenture as the "senior note
indenture." The senior notes are senior unsecured obligations of Oxford and:



     - rank senior in right of payment to all our subordinated indebtedness;



     - rank equally in right of payment with all existing and future senior
       indebtedness, including borrowings under the term loan agreement
       described above; and



     - are effectively subordinated to all our existing and future secured
       indebtedness, including indebtedness under the term loan agreement, to
       the extent of the value of the assets securing indebtedness, and the
       senior notes are structurally subordinated to indebtedness and other
       liabilities of our subsidiaries, including any guarantees of our
       subsidiaries of indebtedness under the term loan agreement.



     As of the date of this prospectus, we had $200 million of senior notes
outstanding.



     The senior notes mature on May 15, 2005. Interest on the senior notes is
payable semi-annually at the rate of 11% per annum.



     On and after May 15, 2002, we will have the right to redeem any or all of
the senior notes at the following redemption prices plus accrued and unpaid
interest on the senior notes to the date of redemption:



<TABLE>
<CAPTION>
                                                          PERCENTAGE OF
           12-MONTH PERIOD BEGINNING MAY 15,             PRINCIPAL AMOUNT

2003...................................................      102.750
2004 and afterwards....................................      100.000
</TABLE>



     On and before May 15, 2001, we have the right to use the net cash proceeds
of one or more equity offerings to redeem up to 33 1/3% of the aggregate
principal amount of senior notes originally outstanding at 111% of the principal
amount, plus accrued and unpaid interest to the redemption date. However, at
least 66 2/3% of the original aggregate principal amount of senior notes must
remain outstanding immediately after the redemption of the senior notes and the
redemption must occur within 60 days of the closing of the equity offering.



     If an event treated as a "change of control" as such term is used in the
senior note indenture of Oxford occurs, each holder of senior notes will have
the right to require us to make an offer to purchase from it all or any part of
the senior notes it holds then outstanding at a purchase price in cash equal to
101% of their aggregate principal amount, plus accrued and unpaid interest on
the senior notes.

<PAGE>   68


COVENANTS



     The term loan agreement and the senior note indenture contain substantially
similar covenants which, among other things, and subject to important
exceptions, restrict our ability and the ability of our subsidiaries to:



     - pay dividends or make payments or distributions;



     - incur additional indebtedness;



     - make investments, loans or advances;



     - make acquisitions;



     - incur liens;



     - enter into sale and leaseback transactions;



     - engage in mergers or consolidations;



     - sell stock or assets of our principal subsidiaries;



     - change the business conducted by us or our subsidiaries; and



     - enter into transactions with affiliates and otherwise restrict certain
       corporate activities.



EVENTS OF DEFAULT



     The term loan agreement and the senior note indenture provide that certain
events will constitute events of default, which include but are not limited to:



     - failure to make payments when due;



     - a default by us or by our restricted subsidiaries under other agreements
       governing indebtedness;



     - our failure to observe or perform the covenants set forth in the term
       loan agreement or in the senior note indenture;



     - the imposition of certain judgments against us or our restricted
       subsidiaries; and



     - the incurrence of certain bankruptcy or insolvency proceedings or events
       with respect to us or our restricted subsidiaries.



RESTRICTED PAYMENTS



     The term loan agreement and the senior note indenture contain covenants
that restrict our ability to make certain "restricted payments," including our
ability:



     - to declare or pay dividends or make payments or distributions on the
       capital stock of Oxford or its restricted subsidiaries or warrants,
       options or other rights to purchase the capital stock of Oxford or its
       restricted subsidiaries;



     - to purchase, redeem or otherwise acquire or retire for value equity
       interests of Oxford or its restricted subsidiaries; or



     - to prepay, purchase, redeem, defease or otherwise acquire or retire for
       value prior to its stated maturity indebtedness that is subordinated to
       the term loan, in the case of the term loan agreement, or indebtedness
       that is subordinated to the senior notes, in the case of the senior note
       indenture;


                                       64
<PAGE>   69


UNLESS:



     (1) no default or event of default has occurred and is continuing or would
         occur as a consequence thereof; and



     (2) after giving effect to the restricted payment, Oxford has a fixed
         charge coverage ratio -- that is, a ratio of consolidated net income,
         plus, to the extent deducted from consolidated net income, fixed
         charges and non-cash dividends on Oxford's preferred stock, plus taxes,
         depreciation, amortization, depletion and other non-cash charges
         required to be reflected as expenses, minus cash payments with respect
         to non-recurring, non-cash charges previously added back as described
         above, to consolidated fixed charges -- of at least 2.25 to 1 for the
         most recent four quarters, and such restricted payment when taken
         together with all other restricted payments relating to such period
         shall not exceed 50% of consolidated net income of Oxford for that
         period.



     These restrictions are subject to certain exceptions, including the ability
to pay dividends payable in offered preferred stock on shares of offered
preferred stock. We are only able to make payments of dividends on offered
preferred stock in shares of offered preferred stock until May 13, 2000. After
that date, dividend payments on the offered preferred stock must be in cash.
Unless we comply with the restricted payment covenant described above, we may be
prohibited from making a payment of cash dividends on our offered preferred
stock.



     These restrictions do not relieve us from our obligations to pay dividends
on the offered preferred stock when due.



     We are also prohibited from redeeming the offered preferred stock or the
debentures unless we comply with the restricted payment covenant described
above. These restrictions do not relieve us from our obligations to redeem the
offered preferred stock or the debentures upon a change in control. If we fail
to make dividend payments on the offered preferred stock when due, additional
dividends will accumulate on any unpaid dividends.



CHANGE OF CONTROL



     A number of factors may limit our ability to redeem the offered preferred
stock or debentures upon a change of control. The term loan agreement provides
that certain change of control events with respect to Oxford require us to
prepay amounts outstanding under the term loan agreement at 101% of the
aggregate principal amount of the term loan plus accrued and unpaid interest,
although each lender has the right to waive its entitlement to prepayment. In
addition, certain events that may obligate us to prepay outstanding obligations
under the term loan agreement do not constitute a change of control under the
certificates of designations relating to the offered preferred stock or under
the indentures relating to the debentures.



     In addition, the senior note indenture provides that certain change of
control events with respect to Oxford give the holders of senior notes the right
to require us to repurchase all or any part of the holders' senior notes, in a
"change of control offer." The offer price will be in cash equal to 101% of the
aggregate principal amount of the notes plus accrued and unpaid interest to the
date of purchase.



     If a change of control occurs, we may not have sufficient resources to
repay indebtedness under the term loan agreement, and we may not have sufficient
resources to repurchase the senior notes tendered in a change of control offer
or redeem offered preferred stock or the debentures upon a change of control.
Furthermore, any future credit


                                       65
<PAGE>   70


agreements or other agreements relating to senior indebtedness to which we
become a party may contain similar restrictions and provisions. In the event a
change of control occurs at a time when we are directly or indirectly prohibited
from repurchasing the senior notes or redeeming offered preferred stock or the
debentures, we could seek the consent of our lenders to the redemption of
offered preferred stock or debentures or could attempt to refinance the
borrowings that contain this prohibition. If we do not obtain the consent or
repay the borrowings, the repurchase of the senior notes tendered in a change of
control offer or redemption of offered preferred stock or the debentures will
remain prohibited. Our failure to repurchase the senior notes tendered in a
change of control offer or redeem the debentures when required may constitute a
breach of the relevant indentures, which would, in turn, constitute a default
under the term loan agreement or the senior note indenture and could lead to the
acceleration of the indebtedness under the term loan agreement or the senior
note indenture.



     The obligations described above do not relieve us from our obligation to
redeem shares of offered preferred stock or to redeem debentures upon a change
of control. If we are required to redeem the offered preferred stock or the

case of the debentures.


                            SELLING SECURITYHOLDERS

     This section sets forth information with respect to each selling
securityholder for whom we are registering securities for offer and sale to the
public under the registration statement of which this prospectus is a part. The
securities offered hereby are comprised of:

     - 277,629.157 shares of Series D preferred stock, including 14,022.606
       additional shares of Series D preferred stock that we expect to issue as
       dividends on existing shares through May 13, 2000;

     - 132,808.069 shares of Series E preferred stock, including 16,908.793
       additional shares of Series E preferred stock that we expect to issue as
       dividends on existing shares through May 13, 2000;


     - $277,629,157 aggregate principal amount of Series D junior subordinated
       debentures issuable in exchange for shares of Series D preferred stock;



     - $132,808,069 aggregate principal amount of Series E junior subordinated
       debentures issuable in exchange for shares of Series E preferred stock;


     - 15,800,000 Series A warrants;

     - 6,730,000 Series B warrants;

     - 15,800,000 shares of common stock issuable upon exercise of the Series A
       warrants; and


     - 6,730,000 shares of common stock issuable upon exercise of the Series B
       warrants.



     In addition to the information included in this section, if shares of
offered preferred stock, debentures, warrants or shares of common stock are
offered by a selling securityholder under this prospectus, a prospectus
supplement, if required, will include the following information:


                                       66
<PAGE>   71


     - the amount of shares of offered preferred stock, debentures, warrants or
       shares of common stock to be offered for the selling securityholder's
       account;



     - the amount of shares of offered preferred stock, debentures, warrants or
       shares of common stock to be owned by the selling securityholder after
       completion of the offering; and



     - the percentage of the series of offered preferred stock, debentures,
       warrants or common stock, if one percent or more, to be owned by the
       selling securityholder after completion of the offering.



     Under the investment agreement, the selling securityholders named in this
prospectus purchased 245,000 shares of our Series A preferred stock, 105,000
shares of our Series B preferred stock and the warrants for a total sum of $350
million. On February 13, 1999, we entered into a share exchange agreement with
the selling securityholders to redistribute the total amount of the dividends
payable among the shares of Series A preferred stock and Series B preferred
stock. Under the share exchange agreement, the 245,000 shares of Series A
preferred stock were exchanged for 260,146.909 shares of Series D preferred
stock, and the 105,000 shares of Series B preferred stock were exchanged for
111,820.831 shares of Series E preferred stock. The additional amounts of Series
D preferred stock and Series E preferred stock issued in the exchange are
attributable to dividends accrued on the offered preferred stock through
February 13, 1999. As a result of the exchange, the selling securityholders hold
only shares of Series D preferred stock and shares of Series E preferred stock
and following the exchange all shares of the Series A preferred stock and all
shares of the Series B preferred stock were cancelled. The terms of the Series D
preferred stock are substantially similar to the terms of the Series A preferred
stock and the terms of the Series E preferred stock are substantially similar to
the terms of the Series B preferred stock, except with respect to applicable
dividend rates and the use of Series D preferred stock as consideration for
exercise of the warrants. The exchange was effected primarily to facilitate the
potential sale of shares of offered preferred stock by the selling
securityholders.


     As of the date of this prospectus, the selling securityholders held a total
of 263,606.551 shares of Series D preferred stock and 115,899.276 shares of
Series E preferred stock. Through May 13, 2000, we expect to issue an additional
14,022.606 shares of Series D preferred stock and 16,908.793 shares of Series E
preferred stock to satisfy our obligation to pay dividends on the outstanding
shares of offered preferred stock.


     Under the investment agreement, we agreed to increase the number of our
directors to a minimum of 11 directors and a maximum of 13 directors and to
appoint Norman C. Payson, M.D., as our chief executive officer and as a
director. We also agreed that TPG Partners II and its affiliates would be
entitled to nominate four directors to our board of directors, subject to
adjustment based on the number of warrants and warrant stock beneficially owned
by TPG Partners II and its affiliates. Dr. Payson was elected chief executive
officer and joined our board of directors in May 1998. David Bonderman, Jonathan
J. Coslet and James G. Coulter were nominated by TPG Partners II and its
affiliates pursuant to the investment agreement and joined our board of
directors in May 1998. Kent J. Thiry was also nominated by TPG Partners II and
its affiliates pursuant to the investment agreement and joined our board of
directors in August 1998.



     Mr. Bonderman is a director and president of TPG Advisors II, Inc., Mr.
Coulter is a director and vice president of TPG Advisors II, Inc., and Mr.
Coslet is an executive of TPG Advisors II, Inc. TPG Advisors II, Inc. is the
general partner of TPG GenPar II,


                                       67
<PAGE>   72


L.P., which is the general partner of each of TPG Partners II, L.P., TPG
Parallel II, L.P. and TPG Investors II, L.P., each a selling securityholder.



     The investment agreement also contains covenants which restrict our ability
to take significant actions without the consent of TPG Partners II and its
affiliates, including mergers, consolidations and certain issuances of equity
securities. In connection with the investment agreement, we also entered into a
registration rights agreement in which we agreed to register the offered
preferred stock, the debentures, the warrants and the common stock issuable upon
exercise of the warrants under the Securities Act for offer and sale by the
selling securityholders and certain holders to whom they may transfer those
securities. For a summary of certain provisions of the registration rights
agreement, see "Registration Rights Agreement" on page 46.



     We have filed with the SEC under the Securities Act a shelf registration
statement on Form S-3, of which this prospectus is a part, with respect to the
offer and sale of the securities described in this prospectus. We have agreed,
among other things, to bear certain expenses in connection with the registration
and sale of the securities being offered by the selling securityholders. For
more information regarding these expenses, see "Plan of Distribution" beginning
on page 72.

                              PLAN OF DISTRIBUTION


     The selling securityholders now hold shares of offered preferred stock and
warrants covered by this prospectus. As used in the rest of this section of this
prospectus, the term "selling securityholders" includes the selling
securityholders named in the table under "Selling Securityholders" beginning on
page 66 of this prospectus and some of their pledgees, donees, transferees or
other successors in interest selling securities received from a named selling
securityholder after the date of this prospectus. The shares of offered
preferred stock, the debentures issuable upon an exchange of offered preferred
stock, the warrants and the shares of common stock issuable upon exercise of the
warrants covered by this prospectus are referred to in this section as the
"registrable securities." The selling securityholders may offer and sell, from
time to time, some or all of the registrable securities under this prospectus.
We have registered the registrable securities for offer and sale by the selling
securityholders so that the registrable securities will be freely tradeable by
them. Registration of the registrable securities does not mean, however, that
the registrable securities necessarily will be offered or sold. We will not
receive any proceeds from any sale by the selling securityholders of the
registrable securities. See "Use of Proceeds" on page 48 for information about
the use of proceeds from the original sale of the offered preferred stock and
the warrants. We will pay all costs, expenses and fees in connection with the
registration of the registrable securities, including fees of our counsel and
accountants, fees payable to the SEC, listing fees and the reasonable fees and
disbursements of one law firm selected as counsel for the selling
securityholders in connection with the registration. The selling securityholders
will pay all underwriting discounts and commissions and similar selling
expenses, if any, attributable to the sale of the registrable securities.



     The selling securityholders may sell the registrable securities from time
to time, at market prices prevailing at the time of sale, at prices related to
market prices, at a fixed price, at prices subject to change or at negotiated
prices, by a variety of methods, including the following:


     - on markets where our securities are traded or on an exchange in
       accordance with the rules of the exchange;

     - in privately negotiated transactions;

     - through broker-dealers, which may act as agents or principals;


     - in a block trade in which a broker-dealer will attempt to sell a block of
       registrable securities as agent but may position and resell a portion of
       the block as principal to facilitate the transaction;


     - through one or more underwriters on a firm commitment or best-efforts
       basis;

     - directly to one or more purchasers;

     - through agents;


     - through option transactions, forward contracts, equity swaps or other
       derivative transactions relating to the registrable securities;



     - through short sales of the registrable securities;


     - in any combination of the above; or

     - by any other legally available means.

                                       72
<PAGE>   77

     In effecting sales, brokers or dealers engaged by the selling
securityholders may arrange for other brokers or dealers to participate.
Broker-dealer transactions may include:


     - purchases of the registrable securities by a broker-dealer as principal
       and resales of the registrable securities by the broker-dealer for its
       account pursuant to this prospectus;


     - ordinary brokerage transactions; or

     - transactions in which the broker-dealer solicits purchasers.


     If we or the selling securityholders enter into a material arrangement with
any underwriter, broker, dealer or other agent for the sale of any registrable
securities through a secondary distribution or a purchase by a broker or dealer,
or if we or the selling securityholders make other material changes in the plan
of distribution of the registrable securities, we will file a prospectus
supplement, if necessary, under the Securities Act disclosing the material terms
and conditions of such arrangement. If we or the selling securityholders use an
underwriter or underwriters in the sale of registrable securities, we and the
selling securityholders expect to execute an underwriting agreement with the
underwriter or underwriters at the time an agreement for the sale is reached. We
will set forth the underwriter or underwriters with respect to an underwritten
offering of registrable securities and the other material terms and conditions
of the underwriting in a prospectus supplement relating to such offering and, if
we or the selling securityholders use an underwriting syndicate, we will set
forth the managing underwriter or underwriters on the cover of the prospectus
supplement. In connection with the sale of registrable securities, underwriters
will receive compensation in the form of underwriting discounts or commissions
and may also receive commissions from purchasers of registrable securities for
whom they may act as agent. Underwriters may sell to or through dealers, and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agent.



     The selling securityholders and any underwriters, broker-dealers or agents
participating in the distribution of the registrable securities may be deemed to
be "underwriters" within the meaning of the Securities Act, and any profit on
the sale of the registrable securities by the selling securityholders and any
commissions received by any such underwriters, broker-dealers or agents may be
deemed to be underwriting commissions under the Securities Act. We have agreed
to indemnify the selling securityholders and each person or entity which
participates as or may be deemed to be an underwriter in the offering or sale of
the selling securityholders' registrable securities against certain liabilities
(and to contribute to payments in respect of those liabilities), including
liabilities arising under the Securities Act. The selling securityholders may
agree to indemnify any agent or broker-dealer that participates in transactions
involving offers or sales of the registrable securities against certain
liabilities, including liabilities arising under the Securities Act.


                             VALIDITY OF SECURITIES


     The validity of the shares of offered preferred stock, the debentures, the
warrants and the shares of common stock offered hereby will be passed upon for
us by Sullivan & Cromwell, New York, New York.

     The consolidated financial statements of Oxford Health Plans, Inc. at
December 31, 1998, and for the year then ended, included in Oxford Health Plans,
Inc.'s annual report on Form 10-K/A No. 2 for the year ended December 31, 1998,
as amended by our Form 10-K/A No. 3, which is incorporated in this prospectus by
reference, have been audited by Ernst & Young LLP, independent auditors, and at
December 31, 1997, and for each of the years in the two-year period ended
December 31, 1997, by KPMG LLP, independent auditors, as set forth in their
respective reports thereon included therein and incorporated in this prospectus
by reference. These consolidated financial statements are incorporated in this
prospectus by reference in reliance upon such reports given on the authority of
these firms as experts in accounting and auditing.



     With respect to the unaudited condensed consolidated interim financial
information for the three-month period ended March 31, 1999, the three-month and
six-month periods ended June 30, 1999 and 1998 and the three-month and
nine-month periods ended September 30, 1999 and 1998 incorporated by reference
in this prospectus, Ernst & Young LLP has reported that it has applied limited
procedures in accordance with professional standards for a review of such
information. Ernst & Young LLP's separate reports, included in Oxford Health
Plans, Inc.'s quarterly report on Form 10-Q/A No. 2 for the quarter ended March
31, 1999 with respect to the unaudited financial information as of March 31,
1999 and the three month periods ended March 31, 1999 and 1998 and Oxford Health
Plans, Inc.'s quarterly reports on Form 10-Q for the quarters ended June 30,
1999 and September 30, 1999 with respect to the unaudited financial information
as of June 30 and September 30, 1999 and the three month periods ended June 30,
and September 30, 1999 and 1998 and the six month periods ended June 30, 1999
and 1998 and the nine month periods ended September 30, 1999 and 1998 and
incorporated in this prospectus by reference, state that it did not audit and it
does not express an opinion on that interim financial information. Accordingly,
the degree of reliance on its reports on such information should be restricted
considering the limited nature of the review procedures applied. The independent
auditors are not subject to the liability provisions of Section 11 of the
Securities Act of 1933 for its reports on the unaudited interim financial
information because those reports are not a "report" or a "part" of the
registration statement prepared or certified by the auditors within the meaning
of Sections 7 and 11 of the Securities Act of 1933.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law permits indemnification
against expenses, fines, judgments and settlements incurred by any director,
officer or employee of Oxford in the event of pending or threatened civil,
criminal, administrative or investigative proceedings, if such person was, or
was threatened to be made, a party by reason of the fact that he is or was a
director, officer or employee of Oxford. Section 145 also provides that the
indemnification provided for therein shall not be deemed exclusive of any other
rights to which those seeking indemnification may otherwise be entitled.

     Article Eighth of the Second Amended and Restated Certificate of
Incorporation, as amended, of Oxford provides that Oxford shall indemnify its
officers and directors to the fullest extent permitted by law. Article Ninth of
the Second Amended and Restated Certification of Incorporation, as amended, of
Oxford provides that to the fullest extent permitted by the Delaware General
Corporation Law as the same exists or may hereafter be amended, a director of
Oxford shall not be liable to Oxford or its stockholders for monetary damages
for breach of fiduciary duty as a director.

     Section 6.4 of the Amended and Restated By-laws of Oxford states:

     Section 6.4.  INDEMNIFICATION OF DIRECTORS, OFFICERS AND EMPLOYEES.  The
Corporation shall indemnify to the fullest extent permitted by law any person
made or threatened to be made a party to any action, suit or proceeding, whether
criminal, civil, administrative or investigative, including any action
instituted by or on behalf of the Corporation, by reason of the fact that such
person or such person's testator or intestate is or was a director or officer of
the Corporation or serves or served at the request of the Corporation any other
enterprise as a director or officer. Expenses incurred by any such person in
defending any such actions, suit or proceeding shall be paid or reimbursed by
the Corporation promptly upon receipt by it of an undertaking of such person to
repay such expense if it shall ultimately be determined that such person is not
entitled to be indemnified by the Corporation. The rights provided to any person
by this by-law shall be enforceable against the Corporation by such person who
shall be presumed to have relied upon it in serving or continuing to serve as a
director or officer as provided above. No amendment of this

                                      II-1
<PAGE>   83

by-law shall impair the rights of any person arising at any time with respect to
events occurring prior to such amendment. To the extent permitted by Delaware
law, the Board may cause the Corporation to indemnify and reimburse other
employees of the Corporation as it deems appropriate. For purposes of this
by-law, the term "Corporation" shall include any predecessor of the Corporation
and any constituent corporation (including any constituent of a constituent)
absorbed by the Corporation in a consolidation or merger; the term "other
enterprise" shall include any corporation, partnership, joint venture, trust or
employee benefit plan; service "at the request of the Corporation" shall include
service as a director or officer of the Corporation, which imposes duties on, or
involves services by, such director or officer with respect to any other
enterprise or any employee benefit plan, its participants or beneficiaries; any
excise taxes assessed on a person with respect to an employee benefit plan,
shall be deemed to be indemnifiable expenses; and action by a person with
respect to any employee benefit plan which such person reasonably believes to be
in the interest of the participants and beneficiaries of such plan shall be
deemed to be action not opposed to the best interests of the Corporation.

     Section 145 of the Delaware General Corporation Law permits the
indemnification provided for by the above by-law provision. The statute further
permits Oxford to insure itself for such indemnification.

     Oxford maintains insurance coverage for its directors and officers with
respect to certain liabilities incurred in their capacities as such and for
Oxford with respect to any payments which it becomes obligated to make to such
persons under the foregoing by-law and statutory provisions.

ITEM 17.  UNDERTAKINGS

     1.  The undersigned registrant hereby undertakes:

     (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 of 1933;

         (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 and of the estimated maximum offering range may be
              reflected in the form of a prospectus filed with the Commission
              pursuant to Rule 424(b) if, in the aggregate, the changes in
              volume and price represent no more than 20 percent change in the
              maximum aggregate offering price set forth in the "Calculation of
              Registration Fee" table in the effective registration statement;
              and

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

     (b) That, for the purpose of determining any liability under the Securities
         Act of 1933, 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.

     (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.

     2.  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) 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.

     3.  Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions referred to in Item 15 of this
Registration Statement, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable. In the event that a claim for indemnification by the
registrant against such liabilities (other than the payment by the registrant of
expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in

                                      II-4
<PAGE>   86

connection with the securities being registered, the registrant will, unless in
the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by them is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

     4.  The undersigned registrant hereby undertakes that:

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

          (b) For the purpose of determining any liability under the Securities
              Act of 1933, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof.


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

         Debentures in accordance with Section 6.5; provided, that, if the

         the Trustee has been made; and

                                 THE DEBENTURES

                  Section 2.1. Form and Dating. (a) The Debentures are being
issued by the Company in exchange for the Company's Series D Cumulative

Debentures and the Trustee's certificate of authentication shall be

omissions, substitutions and other variations as are required by law or
permitted by this Indenture.

                  (b) The terms and provisions contained in the Debentures, the
form of which is annexed hereto as Exhibit A, shall constitute, and are hereby
expressly made, a part of this Indenture and, to the extent applicable, the
Company and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. The
Debentures may have such other notations, legends or endorsements as are
required by law,

                                       8
<PAGE>   15
stock exchange rule or usage. The Company and the Trustee shall approve the form
of the Debentures and any notation, legend or endorsement on them. Each
Debenture shall be dated the date of its authentication.

                  (c) The Debentures shall be issuable only in fully registered
form, without coupons. The Debentures may be issued in any denomination;
provided, however, to the extent possible Debentures will be issued in
denominations of $1,000 and integral multiples thereof.

                  (d) The Debentures are transferable only in denominations of
$1,000 and integral multiples of $1,000; provided, however, that, if the
aggregate amount of Debentures that a Holder wishes to transfer is not equal to
$1,000 or an integral multiple thereof, such Holder may transfer one Debenture
in a denomination less than $1,000.

                  Section 2.2. Global Debentures. This section shall apply only
to Global Debentures deposited with or on behalf of the Depositary.

                  (a) Each Global Debenture authenticated under this Indenture
shall be registered in the name of the Depositary designated by the Company for
such Global Debenture or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Debenture shall
constitute a single Debenture for all purposes of this Indenture.

                  (b) Notwithstanding any other provision in this Indenture, no
Global Debenture may be exchanged in whole or in part for Debentures registered,
and no transfer of a Global Debenture in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Debentures or a
nominee thereof unless (i) such Depositary (A) has notified the Company that it
is unwilling or unable to continue as Depositary for such Global Debentures or
(B) has ceased to be a clearing agency registered as such under the Exchange
Act, and in either case the Company fails to appoint a successor Depositary
within 90 days, (ii) the Company executes and delivers to the Trustee a Company
Order (as defined below) stating that it elects to cause the issuance of the
Debentures in certificated form and that all Global Debentures shall be
exchanged in whole for Debentures that are not Global Debentures (in which case
such exchange shall be effected by the Trustee) or (iii) there shall have
occurred and be continuing an Event of Default or any event which after notice
or lapse of time or both would be an Event of Default with respect to the
Debentures.

                  (c) If any Global Debenture is to be exchanged for other
Debentures or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Registrar, for exchange or
cancellation as provided in this Article. If any Global Debenture is to be
exchanged for other Debentures or canceled in part, or if another Debenture is
to be exchanged in whole or in part for a beneficial interest in any Global
Debenture, then either (i) such Global Debenture shall be so surrendered for
exchange or cancellation as provided in this Article or (ii) the principal
amount thereof shall be reduced or increased by an amount equal to the portion
thereof to be so exchanged or canceled, or equal to the principal amount of such
other Debenture to be so exchanged for a beneficial interest therein, as the
case may be, by means of an appropriate adjustment made on the records of the
Trustee, as Registrar, whereupon the Trustee, in accordance with the Applicable
Procedures, shall instruct the Depositary or its

                                       9
<PAGE>   16
authorized representative to make a corresponding adjustment to its records.
Upon any such surrender or adjustment of a Global Debenture, the Trustee shall,
as otherwise provided in this Article, authenticate and deliver any Debentures
issuable in exchange for such Global Debenture (or any portion thereof) to or
upon the order of the Company, and registered in such names as may be directed
by, the Depositary or its authorized representative. Upon the request of the
Trustee in connection with the occurrence of any of the events specified in the
preceding paragraph, the Company shall promptly make available to the Trustee a
reasonable supply of Debentures that are not in the form of Global Debentures.
The Trustee shall be entitled to rely upon any order, direction or request of
the Depositary or its authorized representative which is given or made pursuant
to this Article if such order, direction or request is given or made in
accordance with the Applicable Procedures.

                  (d) Every Debenture authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
Debenture or any portion thereof, whether pursuant to this Article or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Debenture, unless such Debenture is registered in the name of a Person other
than the Depositary for such Global Debenture or a nominee thereof.

                  (e) The Depositary or its nominee, as registered owner of a
Global Debenture, shall be the Holder of such Global Debenture for all purposes
under this Indenture and the Debentures, and owners of beneficial interests in a
Global Debenture shall hold such interests pursuant to the Applicable
Procedures. Accordingly, any such owner's beneficial interest in a Global
Debenture will be shown only on, and the transfer of such interest shall be
effected only through, records maintained by the Depositary or its nominee or
its Agent Members.

                  Section 2.3. Execution and Authentication. (a) Two Officers,
one of whom shall be the Chairman of the Board, the President, the Chief
Executive Officer or the Chief Financial Officer of the Company, shall sign the
Debentures for the Company by manual or facsimile signature. If an Officer whose
signature is on a Debenture no longer holds that office at the time the Trustee
authenticates the Debenture, the Debenture shall be valid nevertheless.

                  (b) A Debenture shall not be valid until an authorized
signatory of the Trustee authenticates the Debenture. The signature of the
Trustee on a Debenture shall be conclusive evidence that such Debenture has been
duly and validly authenticated and issued under this Indenture. The form of
Trustee's certificate of authentication to be borne by the Debentures shall be
substantially as set forth in Exhibit A hereto.

                  (c) At any time and from time to time after the execution and
delivery of this Indenture, the Trustee shall authenticate and make available
for delivery Debentures for original issue on the Issue Date in an aggregate
principal amount not to exceed $[ ], upon a written order of the Company signed
by two Officers of the Company (a "Company Order"). Such Company Order shall
specify the amount of the Debentures to be authenticated and the date on which
the original issue of Debentures is to be authenticated. Except as expressly set
forth in Article IV, all Debentures issued under this Indenture shall vote and
consent together on all matters as one class.

                                       10
<PAGE>   17
                  (d) The Trustee may appoint an agent (the "Authenticating
Agent") reasonably acceptable to the Company to authenticate the Debentures.
Unless limited by the terms of such appointment, any such Authenticating Agent
may authenticate Debentures whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by the
Authenticating Agent.

                  (e) In case the Company, pursuant to Article V, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of its properties and assets substantially as an
entirety to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have
been merged, or the Person which shall have received a conveyance, transfer,
lease or other disposition as aforesaid, shall have executed an indenture
supplemental hereto with the Trustee pursuant to Article V, any of the
Debentures authenticated or delivered prior to such consolidation, merger,
conveyance, transfer, lease or other disposition may, from time to time, at the
request of the successor Person, be exchanged for other Debentures executed in
the name of the successor Person with such changes in phraseology and form as
may be appropriate, but otherwise in substance of like tenor as the Debentures
surrendered for such exchange and of like principal amount, and the Trustee,
upon Company Order of the successor Person, shall authenticate and deliver
Debentures as specified in such order for the purpose of such exchange. If
Debentures shall at any time be authenticated and delivered in any new name of a
successor Person pursuant to this Section in exchange or substitution for or
upon registration of transfer of any Debentures, such successor Person, at the
option of the Holders but without expense to them, shall provide for the
exchange of all Debentures at the time Outstanding for Debentures authenticated
and delivered in such new name.

                  Section 2.4. Registrar and Paying Agent. (a) The Company shall
maintain an office or agency in the Borough of Manhattan, City of New York,
where Debentures may be presented for registration of transfer or for exchange
(the "Registrar"), where Debentures may be presented for payment (the "Paying
Agent") and for the service of notices and demands to or upon the Company in
respect of the Debentures and this Indenture. The Registrar shall keep a
register of the Debentures and of their transfer and exchange (the "Debenture
Register"). The Company may have one or more co-registrars and one or more
additional paying agents. The term "Paying Agent" includes any additional paying
agent.

                  (b) The Company shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-registrar not a party to this
Indenture, which shall incorporate the terms of the TIA. The agreement shall
implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee of the name and address of each such agent. If
the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act
as such and shall be entitled to appropriate compensation therefor pursuant to
Section 8.7. The Company may act as Registrar, Paying Agent, co-registrar or
transfer agent.

                  (c) The Company initially appoints the Trustee at its
principal corporate trust office in the Borough of Manhattan, City of New York
(the "Corporate Trust Office") as Registrar, Paying Agent and agent for service
of demands and notices in connection with the Debentures and this Indenture, and
as Custodian with respect to the Global Debentures, until such time as the
Trustee has resigned or a successor Trustee has been appointed.

                                       11
<PAGE>   18
                  (d) The Company initially appoints DTC to act as Depositary
with respect to the Global Debentures.

                  Section 2.5. Deposit of Monies; Paying Agent to Hold Money in
Trust. (a) By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Debenture is due and payable, the Company shall
deposit with the Paying Agent in immediately available funds money sufficient to
pay such principal or interest when due.

                  (b) The Company shall require each Paying Agent (other than
the Trustee) to agree in writing that such Paying Agent shall hold in trust for
the benefit of Holders or the Trustee all money held by such Paying Agent for
the payment of principal of or interest on the Debentures and shall notify the
Trustee in writing of any default by the Company in making any such payment. The
Company at any time may require a Paying Agent (other than the Trustee) to pay
all money held by it to the Trustee and to account for any funds disbursed by
such Paying Agent. Upon complying with the previous sentence, the Paying Agent
(if other than the Company or a Subsidiary) shall have no further liability for
the money delivered to the Trustee. If the Company, or any of its Subsidiaries
or Affiliates, acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent.
Upon any bankruptcy, reorganization or similar proceeding with respect to the
Company, the Trustee shall serve as Paying Agent for the Debentures.


                  In case Holders of any Debentures shall not, within two years
after such deposit, claim the cash so deposited, the Trustee or Paying Agent (as
applicable) shall, upon demand, pay over to the Company the balance so
deposited, or (if then held by the Company or any of its Subsidiaries or
Affiliates) such balance shall be discharged from such trust. Thereupon, the
Trustee or Paying Agent (as applicable) shall be relieved of all responsibility
to the Holders thereof, or if the Company or any of its Subsidiaries or
Affiliates acts as Paying Agent, such Paying Agent shall be relieved of all
responsibility as trustee of the cash so deposited; and the sole right of such
Holders shall be as a general creditor thereof. Any interest accrued on any
funds so deposited shall belong to the Company, and shall be paid to it from
time to time on demand.


                  Section 2.6. Holder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders and shall otherwise comply with TIA
Section 312(a). If the Trustee is not the Registrar, or to the extent otherwise
required under the TIA, the Company shall furnish or cause to be furnished to
the Trustee, in writing at least seven Business Days before each interest
payment date and at such other times as the Trustee may request in writing, a
list, in such form and as of such date as the Trustee may reasonably require, of
the names and addresses of Holders and the Company shall otherwise comply with
TIA Section 312(a).

                  Section 2.7.  Legends; Transfers and Exchanges; Etc.

                  (a) Each Debenture shall bear a legend (the "Private Placement
Legend") substantially as set forth below:

                                       12
<PAGE>   19
                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE
                  ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION
                  UNDER SECTION 5 OF THE U.S. SECURITIES ACT OF 1933, AS AMENDED
                  (THE "SECURITIES ACT"), AND WERE NOT REGISTERED UNDER ANY
                  STATE SECURITIES LAW, AND MAY NOT BE OFFERED, SOLD,
                  TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
                  EFFECTIVE REGISTRATION STATEMENT OR PURSUANT TO AN EXEMPTION
                  FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
                  REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE
                  SECURITIES LAWS."

                  (b) The Private Placement Legend shall be removed from a
Debenture if such Debenture is sold pursuant to an effective registration
statement under the Securities Act or there is delivered by the Company to the
Trustee such satisfactory evidence, which may include an opinion of independent
counsel, as reasonably may be requested by the Trustee, to confirm that neither
such legend nor the restrictions on transfer set forth therein are required to
ensure that transfer of such Debenture will not violate the registration and
prospectus delivery requirements of the Securities Act.

                  (c) Restricted Debentures Legend. Upon the transfer, exchange
or replacement of Debentures not bearing a Private Placement Legend, the
Registrar shall deliver Debentures that do not bear a Private Placement Legend.
Upon the transfer, exchange or replacement of Debentures bearing a Private
Placement Legend, the Registrar shall deliver only Debentures that bear a
Private Placement Legend unless:

                           (i) such Debentures are transferred pursuant to an
                  effective registration statement under the Securities Act, or

                           (ii) in connection with such transfer, the Registrar
                  shall have received an Opinion of Counsel satisfactory to it
                  to the effect that neither such legend nor the related
                  restrictions on transfer are required in order to maintain
                  compliance with the provisions of the Securities Act.

The Company shall deliver to the Trustee an Officer's Certificate promptly upon
effectiveness, withdrawal or suspension of any registration statement applicable
to any Debentures.

                  (d) The Registrar shall retain copies of all letters, notices
and other written communications received pursuant to this Article. The Company
shall have the right to inspect and make copies of all such letters, notices or
other written communications at any reasonable time upon the giving of
reasonable written notice to the Registrar.

                  (e) Transfer and Exchange of Certificated Debentures. When
Certificated Debentures are presented by a Holder to the Registrar with a
request to register the transfer of the Certificated Debentures or to exchange
such Certificated Debentures for an equal principal amount of Certificated
Debentures of other authorized denominations, the Registrar shall register the
transfer or make the exchange as requested only if the Certificated Debentures
(i) are presented or surrendered for registration of transfer or exchange, (ii)
are endorsed and contain a

                                       13
<PAGE>   20

signature guarantee or are accompanied by a written instrument of transfer in
form satisfactory to the Registrar duly executed by such Holder or by his
attorney and (iii) contain a signature guarantee, duly authorized in writing.


                  (f) Obligations with Respect to Transfers and Exchanges of
Debentures.

                           (i) To permit registrations of transfers and
         exchanges, the Company shall, subject to the other terms and conditions
         of this Article, execute and the Trustee shall authenticate Debentures
         at the Registrar's or co-registrar's request in accordance with the
         provisions of Section 2.3.

                           (ii) No service charge shall be made to a Holder for
         any registration of transfer or exchange, but the Company may require
         payment of a sum sufficient to cover any stamp or transfer tax,
         assessments, or similar governmental charge payable in connection
         therewith (other than any such stamp or transfer taxes, assessments or
         similar governmental charges payable upon exchange pursuant to Section
         5.1, Article VI or Section 10.5 not involving any transfer).

                           (iii) Prior to the due presentation for registration
         of transfer of any Debenture, the Company, the Trustee, the Paying
         Agent, the Registrar or any co-registrar may deem and treat the Person
         in whose name a Debenture is registered as the absolute owner of such
         Debenture for the purpose of receiving payment of principal of and
         interest on such Debenture and for all other purposes whatsoever,
         whether or not such Debenture is overdue, and none of the Company, the
         Trustee, the Paying Agent, the Registrar or any co-registrar shall be
         affected by notice to the contrary.

                           (iv) All Debentures issued upon any transfer or
         exchange pursuant to the terms of this Indenture shall be valid
         obligations of the Company; shall evidence the same debt; and shall be
         entitled to the same benefits under this Indenture as the Debentures
         surrendered upon such transfer or exchange.

                           (v) The Registrar shall not be required to register
         the transfer of or exchange any Debenture to be redeemed, in whole or
         in part, upon a change of control, except the unredeemed portion of any
         Debenture being redeemed in part.

                  (g) No Obligation of the Trustee. The Trustee shall have no
obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Debenture other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

                  Section 2.8. Mutilated, Destroyed, Lost or Stolen Debentures.
If a mutilated Debenture is surrendered to the Registrar, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Debenture of like tenor and principal amount and bearing a number not
outstanding. If the Holder of a Debenture claims that the Debenture has been
lost, destroyed or wrongfully taken, and if there shall be delivered to the
Company and

                                       14
<PAGE>   21
the Trustee (i) evidence to their reasonable satisfaction of the loss,
destruction or theft of such Debenture and (ii) an indemnity bond sufficient in
the reasonable judgment of the Company and the Trustee to protect the Company,
the Trustee, the Paying Agent and the Registrar and any co-registrar from any
loss any of them may suffer if such Debenture is replaced, then, the Company, in
the absence of notice to the Company or the Trustee that such Debenture has been
acquired by a bona fide purchaser, shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of like tenor and principal amount, bearing a number
not contemporaneously Outstanding if the requirements of Section 8-405 of the
Uniform Commercial Code as in effect in the State of New York are met.


                  In case any such mutilated, destroyed, lost or stolen
Debenture has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Debenture, pay such Debenture.

                  Upon the issuance of any new Debenture under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

                  Every new Debenture issued pursuant to this Section in lieu of
any mutilated, destroyed, lost or stolen Debenture shall constitute an original
additional contractual obligation of the Company and any other obligor upon the
Debentures, whether or not the mutilated, destroyed, lost or stolen Debenture
shall be at any time enforceable by anyone, and shall be entitled to all
benefits of this Indenture equally and proportionately with any and all other
Debentures duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Debentures.

                  Section 2.9. Temporary Debentures. Until definitive Debentures
are ready for delivery, the Company may execute and the Trustee shall
authenticate and deliver temporary Debentures. Temporary Debentures shall be
substantially in the form of definitive Debentures but may have variations that
the Company reasonably considers appropriate for temporary Debentures. Without
unreasonable delay, the Company shall prepare definitive Debentures. After the
preparation of definitive Debentures, the temporary Debentures shall be
exchangeable for definitive Debentures upon surrender of the temporary
Debentures at any office or agency maintained by the Company for that purpose
and such exchange shall be without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Debentures, the Company shall execute,
and the Trustee shall authenticate and make available for delivery in exchange
therefor, one or more definitive Debentures representing an equal principal
amount of Debentures. Until so exchanged, the Holder of temporary Debentures
shall in all respects be entitled to the same benefits under this Indenture as a
Holder of definitive Debentures.

                  Section 2.10. Cancellation. The Company at any time may
deliver Debentures to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee

                                       15
<PAGE>   22
any Debentures surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel and return to the Company all
Debentures surrendered for registration of transfer, exchange, payment,
redemption or cancellation. The Company may not issue new Debentures to replace
Debentures it has paid or delivered to the Trustee for cancellation except as
expressly permitted by this Indenture.

                  Section 2.11. Payment of Interest; Defaulted Interest. (a)
Interest on any Debenture which is payable, and is punctually paid or duly
provided for, on any interest payment date shall be paid to the Person in whose
name such Debenture (or one or more predecessor Debentures) is registered at the
close of business on the regular record date for such interest as provided in
the Debenture at the office or agency of the Company maintained for such purpose
pursuant to Section 2.4.

                  (b) Any interest on any Debenture which is payable, but is not
paid when the same becomes due and payable and such nonpayment continues for a
period of 30 days shall forthwith cease to be payable to the Holder on the
regular record date by virtue of having been such Holder, and such defaulted
interest and (to the extent lawful) interest on such defaulted interest at the
rate borne by the Debentures (such defaulted interest and interest thereon
herein collectively called "Defaulted Interest") shall be paid by the Company,
to the Persons in whose names the Debentures (or their respective predecessor
Debentures) are registered at the close of business on a Special Record Date (as
hereinafter defined) for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Debenture and
the date (not less than 30 days after such notice) of the proposed payment (the
"Special Interest Payment Date"), and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as provided in this clause.
Thereupon the Trustee shall fix a record date (the "Special Record Date") for
the payment of such Defaulted Interest which shall be not more than 15 days and
not less than 10 days prior to the Special Interest Payment Date. The Trustee
shall promptly notify the Company of such Special Record Date, and in the name
and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date and Special Interest Payment
Date therefor to be given in the manner provided for in Section 12.2 not less
than 10 days prior to such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date and Special Interest
Payment Date therefor having been so given, such Defaulted Interest shall be
paid on the Special Interest Payment Date to the Persons in whose names the
Debentures (or their respective predecessor Debentures) are registered at the
close of business on such Special Record Date.

                  (c) Subject to the foregoing provisions of this Section, each
Debenture delivered under this Indenture upon registration of, transfer of, or
in exchange for or in lieu of, any other Debenture shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Debenture.

<PAGE>   23
                  (d) All references in this Indenture and in the Debenture
annexed hereto as Exhibit A to "interest" payable in respect of the Debentures
shall include Defaulted Interest, where applicable.

                  Section 2.12. Record Date. The record date for purposes of
determining the identity of Holders of the Debentures entitled to vote or
consent to any action by vote or consent authorized or permitted under this
Indenture shall be determined as provided for in TIA Section 316(c).

                  Section 2.13. Computation of Interest. Interest on the
Debentures shall be computed on the basis of a 360-day year consisting of twelve
30-day months (four 90-day quarters) and the actual number of days elapsed in
the period for which payable.


                  Section 2.14. CUSIP Number. The Company in issuing the
Debentures may use a "CUSIP" number, and if it does so, the Trustee shall use
the CUSIP number in notices of redemption or exchange as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness or accuracy of the CUSIP number printed in the notice or
on the Debentures and that reliance may be placed only on the other
identification numbers printed on the Debentures. The Company shall promptly
notify the Trustee of any change in the CUSIP number.


                                   ARTICLE III

                                    COVENANTS

                  Section 3.1. Payment of Debentures. (a) The Company shall pay
or cause to be paid the principal of and interest on the Debentures on the dates
and in the manner provided in the Debentures and in this Indenture.

                  (b) The Company shall pay, to the extent such payments are
lawful, interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal (including if due as a result of a
redemption) at the rate specified therefor in the Debentures, and on overdue
installments of interest (without regard to applicable grace periods) at the
rate specified therefor in the Debentures.

                  (c) Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United States of
America from principal or interest payments hereunder.

                  Section 3.2. Maintenance of Office or Agency. (a) The Company
shall maintain each office or agency required under Section 2.4. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee. The Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

                                       17
<PAGE>   24
                  (b) The Company may also from time to time designate one or
more other offices or agencies (in or outside of The City of New York) where the
Debentures may be presented or surrendered for any or all such purposes and may
from time to time rescind any such designation; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, City of
New York for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and any change in the location of
any such other office or agency.

                  Section 3.3. Corporate Existence. Subject to Section 5.1, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the corporate rights (charter
and statutory), licenses and franchises of the Company; provided, however, that
the Company shall not be required to preserve any such right, license or
franchise if the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not, and will not be, disadvantageous
in any material respect to the Holders.

                  Section 3.4. Compliance Certificate. (a) The Company shall
file with the Trustee and the SEC, and transmit to Holders, such information,
documents and other reports, and such summaries thereof, as may be required by
the TIA at the times and in the manner provided pursuant to the TIA.

                  (b) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year of the Company, an Officers' Certificate
stating that in the course of the performance of their duties as Officers of the
Company, the signers would normally have knowledge of any default or Event of
Default and whether or not, to the best of such signer's knowledge (after due
inquiry), any default or Event of Default has occurred during such period. If
such signers state that a default or Event of Default has occurred, the
certificate shall describe the default or Event of Default, its status and what
action the Company is taking or proposes to take with respect thereto. The
Company also shall comply with TIA Section 314(a).

                  Section 3.5. Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

                  Section 3.6. Waiver of Stay, Extension or Usury Laws. The
Company covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Debentures as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent that it may
lawfully do so) the Company hereby expressly waives all benefit or advantage of
any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

<PAGE>   25
                  Section 3.7. Restrictions on Dividends. So long as any
Debentures are Outstanding, the Board of Directors shall not declare, and the
Company shall not pay or set apart for payment any dividend on any capital stock
of the Company or make any payment on account of, or set apart for payment money
for a sinking or other similar fund for, the repurchase, redemption or other
retirement of, any capital stock of the Company or any warrants, rights or
options exercisable for or convertible into any capital stock of the Company
(other than the repurchase, redemption or other retirement of debentures or
other debt securities that are convertible into or exchangeable for any capital
stock of the Company), or make any distribution in respect of capital stock of
the Company, either directly or indirectly, and whether in cash, obligations or
shares of the Company or other property (other than distributions or dividends
in capital stock to the holders of capital stock), and shall not permit any
corporation or other entity directly or indirectly controlled by the Company to
purchase or redeem any capital stock of the Company or any warrants, rights,
calls or options exercisable for or convertible into any capital stock of the
Company (other than the repurchase, redemption or other retirement of debentures
or other debt securities that are convertible into or exchangeable for any
capital stock of the Company) unless prior to or concurrently with such
declaration, payment, setting apart for payment, repurchase, redemption or other
retirement or distribution, as the case may be, all interest that has become due
and payable on the Debentures shall have been paid. Notwithstanding the
foregoing, this Section shall not prohibit the acquisition, repurchase,
exchange, conversion, redemption or other retirement for value by the Company of
Debentures in accordance with this Indenture or of any shares of Trust Preferred
Stock.

                                   ARTICLE IV

                                  VOTING RIGHTS

                  Section 4.1. Voting Rights and Certain Restrictions. (a) The
Investor and its Affiliates, in their capacity as Holders of Debentures, shall
be entitled to vote on all matters voted on by holders of Common Stock, and
shall vote together with shares of Common Stock (and any shares of Series E
Cumulative Preferred Stock or Series E Debentures entitled to vote) as a single
class; provided, however, that (i) such voting rights shall apply to such
Debentures issued to the Investor or any Affiliate of the Investor in exchange
for shares of Series D Cumulative Preferred Stock that had similar voting rights
and (ii) upon transfer of a Debenture or any portion thereof to any Person other
than the Investor or an Affiliate of the Investor, such Person, and any
subsequent transferee, shall not be entitled to such voting rights with respect
to such Debenture or the transferred portion thereof, regardless of whether any
such Debentures are subsequently acquired by the Investor or its Affiliates.

                  (b) With respect to any such vote provided for in subsection
(a), the Investor (together with its Affiliates) shall be entitled with respect
to its Debentures to an aggregate number of votes equal to the Investor
Aggregate Vote Number (as hereinafter defined).

                  The "Investor Aggregate Vote Number" shall equal the number of
Warrant Shares that would be issuable upon the exercise of the Original Warrants
(as hereinafter defined) by the holders thereof (assuming all conditions
precedent to such exercise have been satisfied and that such exercise occurs as
of the record date for such vote), multiplied by the lesser of (x) the quotient
of the number of Original Warrants that are Beneficially Owned by members of the

                                       19
<PAGE>   26
Investor Group, in the aggregate, as of the record date for such vote (excluding
for purposes of this calculation, however, any Original Warrants that have been
transferred on the books of the Company by any member of the Investor Group to
any Person other than a member of the Investor Group, regardless of whether any
such Original Warrants are subsequently acquired by any member of the Investor
Group), divided by the number of Original Warrants, and (y) the quotient of the
aggregate principal amount of Original Debentures (as hereinafter defined) that
are Beneficially Owned by members of the Investor Group, in the aggregate, as of
the record date for such vote (excluding for purposes of this calculation,
however, any Original Debentures transferred by any member of the Investor Group
to any Person other than a member of the Investor Group, regardless of whether
any such Original Debentures are subsequently acquired by any member of the
Investor Group), divided by the aggregate principal amount of the Original
Debentures. The term "Original Warrants" means those Warrants Beneficially Owned
by members of the Investor Group, in the aggregate, as of May 13, 1998. The term
"Original Debentures" means those Debentures Beneficially Owned by members of
the Investor Group, in the aggregate, as of the Issue Date; provided, however,
that "Original Debentures" shall not include any Debentures issued in respect of
Series D Cumulative Preferred Stock previously issued as a dividend on Series D
Cumulative Preferred Stock.

                  (c) If on any date (i) interest due and payable on either the
Debentures or the Series E Debentures shall not have been paid in full (or, if
the Series E Cumulative Preferred Stock has not been exchanged for Series E
Debentures, dividends payable on the Series E Cumulative Preferred Stock shall
have been in arrears and not paid in full) for four consecutive quarterly
periods or (ii) the Company shall have failed to satisfy its obligation to
redeem or repay the principal of either Debentures in accordance with this
Indenture or Series E Debentures in accordance with the Series E Indenture (or,
if the Series E Cumulative Preferred Stock has not been exchanged for Series E
Debentures, the Company shall have failed to satisfy its obligation to redeem
shares of Series E Cumulative Preferred Stock pursuant to the Certificate of
Designations thereof), then the number of directors constituting the Board of
Directors shall, without further action, be increased by two, and the holders of
Debentures and Series E Debentures representing at least a majority of the
aggregate principal amount of Outstanding Debentures and Series E Debentures
shall have, in addition to the other voting rights set forth herein, the
exclusive right, voting together as a single class without regard to series, to
elect the two directors (the "Additional Directors") of the Company to fill such
newly-created directorships (provided, that, if the shares of Series E
Cumulative Preferred Stock have not been exchanged for Series E Debentures, then
the holders of the shares of Series E Cumulative Preferred Stock shall vote
together with the holders of Debentures as a single class, and, for the purposes
of determining a majority of the aggregate principal amount of Debentures and
Series E Cumulative Preferred Stock, one share of Series E Cumulative Preferred
Stock shall be deemed to be equal to a principal amount of $1,000).
Notwithstanding the foregoing, the Investor and its Affiliates shall not be
permitted to elect, pursuant to the preceding sentence, more than the number of
directors that would result in four directors designated for nomination or
elected by the Investor and its Affiliates then being on the Board of Directors
(including directors that the Investor has a right to designate for nomination
to the Board of Directors pursuant to the Investment Agreement); provided, that,
if at the time Holders of Debentures and holders of Series E Debentures (or, if
applicable, holders of shares of Series E Cumulative Preferred Stock) have the
right to elect Additional Directors and (i) the Investor and its Affiliates
Beneficially Own, in the aggregate, Debentures and Series E Debentures
representing a majority of the

                                       20
<PAGE>   27
aggregate principal amount of Outstanding Debentures and Series E Debentures
(or, if the shares of Series E Cumulative Preferred Stock have not been
exchanged for Series E Debentures, a majority of the aggregate principal amount
of the Debentures and Series E Cumulative Preferred Stock), taken together as a
single class, and (ii) the Investor and its Affiliates are not permitted to
elect one or both of the Additional Directors as aforesaid, then the Holders of
Debentures and holders of Series E Debentures (or, if applicable, holders of
shares of Series E Cumulative Preferred Stock) (other than the Investor and its
Affiliates) shall have the right to elect, voting together as a single class,
one Additional Director pursuant to this subsection (c). For the purposes of
determining a majority of the aggregate principal amount of Debentures and
Series E Cumulative Preferred Stock if necessary pursuant to the preceding
sentence, one share of Series E Cumulative Preferred Stock shall be deemed to be
equal to a principal amount of $1,000. Additional Directors shall continue as
directors and such additional voting right shall continue until such time as (a)
all interest due and payable on the Debentures and Series E Debentures and all
dividends accumulated on the Series E Cumulative Preferred Stock, as the case
may be, shall have been paid in full and (b) any redemption obligation with
respect to, or any obligation to repay the principal of, the Debentures, the
Series E Debentures and the Series E Cumulative Preferred Stock, as the case may
be, that has become due shall have been satisfied or all necessary funds shall
have been set aside for payment, as the case may be, at which time such
Additional Directors shall cease to be directors and such additional voting
right of the Holders shall terminate subject to revesting in the event of each
and every subsequent event of the character indicated above and subject to any
rights as to the election of directors provided for the holders of any series of
preferred stock of the Company.

                  (d) In the event that one or more of the Investor Nominees (as
such term is defined in the Investment Agreement) required to be designated for
election to the Board of Directors pursuant to the Investment Agreement are not
so designated or are not elected to the Board of Directors and the Investor or
any of its Affiliates Beneficially Owns Debentures, then the number of directors
constituting the Board of Directors shall, without further action, be increased
by the number of such Investor Nominees not elected to the Board of Directors
pursuant to the Investment Agreement, and such Holder or Holders shall have, in
addition to the other voting rights set forth herein, the exclusive right,
voting separately as a single class, to elect a number of directors to the Board
of Directors equal to the number of such Investor Nominees not elected to the
Board of Directors. Directors elected pursuant to this subsection shall continue
as directors and such additional voting right shall continue until such time as
the requisite number of Investor Nominees are elected to the Board of Directors
pursuant to the Investment Agreement, at which time the directors elected by the
Investor and its Affiliates pursuant to this subsection shall cease to be
directors (unless elected as Investor Nominees), and such additional voting
rights shall terminate subject to revesting in the event of each and every
subsequent event of the character indicated above.

                  (e) (i) The foregoing rights of Holders to take any action as
provided in this Section may be exercised at any annual meeting of stockholders
or at a special meeting of Holders held for such purpose as hereinafter provided
or at any adjournment thereof, or by the written consent, delivered to the
Secretary of the Company, of the Holders of Debentures representing the minimum
principal amount of

                                       21
<PAGE>   28
Outstanding Debentures required to take such action. So long as such right to
vote continues (and unless such right has been exercised by written consent of
the Holders of Debentures representing the minimum principal amount of
Outstanding Debentures required to take such action), the Chairman of the Board
of Directors may call, and upon the written request of Holders of Debentures
representing 20% of the aggregate principal amount of the Outstanding
Debentures, addressed to the Secretary of the Company at the principal office of
the Company, shall call, a special meeting of the Holders entitled to vote as
provided herein. Such meeting shall be held within 60 days after delivery of
such request to the Secretary, at the place and upon the notice provided by law
and in the By-laws of the Company for the holding of meetings of stockholders.

                  (ii) Each director elected pursuant to subsection (c) or (d)
of this Section shall serve until the next annual meeting or until his or her
successor shall be elected and shall qualify, unless the director's term of
office shall have terminated pursuant to the provisions of subsection (c) or (d)
of this Section, as the case may be. In case any vacancy shall occur among the
directors elected pursuant to subsection (c) or (d) of this Section, such
vacancy may be filled for the unexpired portion of the term by vote of the
remaining director or directors theretofore elected by such Holders (and, if
applicable, holders of the Series E Debentures or holders of shares of Series E
Cumulative Preferred Stock) (or such director's or directors' successor in
office), if any. If any such vacancy is not so filled within 20 days after the
creation thereof or if all of the directors so elected shall cease to serve as
directors before their term shall expire, the Holders (and, if applicable,
holders of the Series E Debentures or holders of shares of Series E Cumulative
Preferred Stock) entitled to vote for such director pursuant to the provisions
of subsection (c) or (d) of this Section, as the case may be, may elect
successors to hold office for the unexpired terms of any vacant directorships,
by written consent as herein provided, or at a special meeting of such Holders
called as provided herein. The Holders of Debentures (and, if applicable,
holders of the Series E Debentures or holders of shares of Series E Cumulative
Preferred Stock) representing a majority of the principal amount of Debentures
entitled to vote for directors pursuant to subsection (c) or (d) of this
Section, as the case may be, shall have the right to remove with or without
cause at any time and replace any directors such Holders (and, if applicable,
holders of the Series E Debentures or holders of shares of Series E Cumulative
Preferred Stock) have elected pursuant to such section, by written consent as
herein provided, or at a special meeting of such Holders (and, if applicable,
holders of the Series E Debentures or holders of shares of Series E Cumulative
Preferred Stock) called as provided herein.

                  (f) Without the consent or affirmative vote of the Holders of
Debentures, voting separately as a class, representing at least a majority of
the aggregate principal amount of Outstanding Debentures, the Company shall not
authorize, create or issue, or increase the authorized amount of any class or
series of capital stock or any security convertible into or exercisable for any
class or series of capital stock, redeemable mandatorily or redeemable at the
option of the holder thereof at any time on or prior to May 13, 2008 (whether or
not only upon the occurrence of a specified event); provided, however, that no
consent or vote of the Holders shall be required for the creation or issuance by
a trust formed at the direction of the Company of any series of preferred
securities of such trust for financing purposes in an aggregate amount not to
exceed $250,000,000 ("Trust Preferred Stock").

                  (g) Without the consent or affirmative vote of the Holders of
Debentures, voting separately as a class, representing at least a majority of
the aggregate principal amount of Outstanding Debentures, the Company shall not
(i) amend, alter or repeal any provision of the Certificate of Incorporation or
the By-laws of the Company, if the amendment, alteration or

                                       22
<PAGE>   29
repeal alters or changes the rights of the Holders of the Debentures so as to
affect them materially and adversely, or (ii) authorize or take any other action
if such action alters or changes any of the rights of Holders of the Debentures
in any respect or otherwise would be inconsistent with the provisions of this
Indenture and the holders of any class or series of the capital stock of the
Company are entitled to vote thereon.

                  (h) The Company shall not enter into any agreement or issue
any security that prohibits, conflicts or is inconsistent with, or would be
breached by, the Company's performance of its obligations hereunder.

                                SUCCESSOR COMPANY

                  Section 5.1. Merger, Consolidation and Sale of Assets. The
Company shall not consolidate with or merge with or into, or convey, transfer or
lease all or substantially all its assets to, any Person, unless:

                  (i) the resulting, surviving or transferee Person (the
         "Successor Company") shall be a corporation, partnership, trust,
         limited liability company or other similar entity organized and
         existing under the laws of the United States of America, any State
         thereof or the District of Columbia and the Successor Company (if not
         the Company) shall expressly assume, by supplemental indenture,
         executed and delivered to the Trustee, in form satisfactory to the
         Trustee, all the obligations of the Company under the Debentures and
         this Indenture;

                  (ii) immediately after giving effect to such transaction, no
         default or Event of Default shall have occurred and be continuing;

                  (iii) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger or transfer and such supplemental indenture, if
         any, comply with this Indenture.

                  For purposes of this Section the sale, lease, conveyance,
assignment, transfer, or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Company, which
properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the transfer of all or
substantially all of the properties and assets of the Company.

                  The Successor Company will succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture,
but, in the case of a lease of all or substantially all its assets, the Company
will not be released from the obligation to pay the principal of and interest on
the Debentures.

                            REDEMPTION OF DEBENTURES

                  Section 6.1. Redemption. The Debentures may or shall (as
applicable) be redeemed, subject to the conditions and at the Redemption Prices
specified in the form of Debentures set forth in Exhibit A hereto.

                  Section 6.2. Applicability of Article. Redemption of
Debentures, as permitted or required by any provision of this Indenture, shall
be made in accordance with this Article.

                  Section 6.3. Notice of Redemption. (a) Notwithstanding the
provisions of Section 12.2, notice of redemption shall be given in the manner
provided for in this Section.

                  (b) Notice of the redemption of Debentures (a "Notice of
Redemption") shall be sent to each Holder to be redeemed by first class mail,
postage prepaid, at each such Holder's address as it is registered in the
Debenture Register, not more than 120 days nor fewer than 90 days prior to the
date fixed for redemption, which date shall be set forth in such notice (the
"Redemption Date"); provided, that failure to give such Notice of Redemption to
any Holder, or any defect in such Notice of Redemption to any Holder shall not
affect the validity of the proceedings for the redemption of Debentures held by
any other Holder. Notwithstanding the foregoing, in the event that
contemporaneously with or prior to the delivery of a Notice of Redemption, the
Company irrevocably deposits, in accordance with Section 6.5, funds sufficient
to pay the aggregate Redemption Price (as defined in Exhibit A hereto) for the
Debentures, such Notice of Redemption shall be delivered not more than 120 days
nor fewer than 30 days prior to the Redemption Date; provided, however, that, if
such Notice of Redemption is delivered fewer than 60 days prior to the
Redemption Date and the Investor or any of its Affiliates Beneficially Owns
Debentures as of the date of the Notice of Redemption and uses its reasonable
best efforts to consummate the sale of all or a portion of its Debentures prior
to the stated Redemption Date but has not completed such sale, the Company
shall, at the option of the Investor (or any such Affiliate), delay such
Redemption Date for a period not to exceed 30 days as requested by the Investor
(or any such Affiliate) in order to complete such sale or sales, and shall
notify the Holders of such delay within five days of receiving the request
therefor. Any delay of the Redemption Date pursuant to the proviso to the
preceding sentence shall be requested by the Investor (or any such Affiliate) in
writing no later than the tenth day preceding the then-scheduled Redemption Date
stated in the Notice of Redemption. The Redemption Date stated in a Notice of
Redemption shall not be delayed pursuant to this subsection more than once in
connection with the redemption of Debentures pursuant to such Notice of
Redemption.

                  (c) All Notices of Redemption shall state:

                           (1)  the Redemption Date,

                           (2)  the Redemption Price,

                           (3) that on the Redemption Date the Redemption Price
         will become due and payable upon each such Debenture, or the portion
         thereof, to be redeemed, and, unless the Company defaults in making the
         redemption payment, that interest on

                                       24
<PAGE>   31
         Debentures called for redemption (or the portion thereof) will cease to
         accrue on and after said date,

                           (4) the place or places where such Debentures are to
         be surrendered for payment of the Redemption Price,

                           (5)  the name and address of the Paying Agent,

                           (6) that Debentures called for redemption must be
         surrendered to the Paying Agent to collect the Redemption Price, and

                           (7) the CUSIP number of the Debentures.

                  (d) From and after the Redemption Date, all interest on
Debentures shall cease to accrue and all rights of the Holders thereof as
Holders of Debentures shall cease and terminate, except to the extent the
Company shall default in payment thereof on the Redemption Date.

                  (e) Prior to any Redemption Date that has been fixed by the
Company in accordance with this Section, the Company shall take all measures
reasonably requested by the Investor to facilitate a sale or other disposition
of Debentures by the Investor or its Affiliates prior to such Redemption Date,
including, without limitation, participation in due diligence sessions and
provision of information about the management, business and financial condition
of the Company, preparation of offering memoranda, private placement memoranda
and other similar documents and preparation and delivery of such other
certificates or documents reasonably requested by the Investor.

                  Section 6.4. Change of Control Notice and Redemption
Procedures. (a) In the event there occurs a Change of Control, any Holder, in
accordance with the procedures set forth below, may require the Company to
redeem any or all of the Debentures held by such Holder at the Redemption Price
therefor. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption in the event of a Change of
Control pursuant to this Section shall relate, in the case of any Debenture
redeemed only in part, to the portion of the principal amount of such Debenture
which has been or is to be redeemed.

                  (b) Notice of any Change of Control shall be sent to the
Holders not more than five days following a Change of Control, which notice (a
"Change of Control Notice") shall describe the transaction or transactions
constituting such Change of Control and set forth each Holder's right to require
the Company to redeem any or all Debentures held by him or her or any portion
thereof, the Redemption Date (which date shall be not more than 30 days from the
date of such Change of Control Notice) and the procedures to be followed by such
Holder in exercising its right to cause such redemption; provided, however, that
if Debentures are owned by more than 50 Holders or groups of Affiliated Holders
and if the Debentures are listed on any national securities exchange or quoted
on any national quotation system, the Company shall give such Change of Control
Notice by publication in a newspaper of general circulation in the Borough of
Manhattan, The City of New York, within 30 days following such Change of Control
and, in any case, a similar notice shall be mailed concurrently to each Holder.
Failure by the Company to give the Change of Control Notice as prescribed by the
preceding sentence, or the

                                       25
<PAGE>   32
formal insufficiency of any such Change of Control Notice, shall not prejudice
the rights of any Holder to cause the Company to redeem any such Debentures held
by him or her.

                  (c) In the event a Holder shall elect to require the Company
to redeem any or all such Debentures or any portion thereof pursuant to Section
6.4(a), such Holder shall deliver, prior to the Redemption Date as set forth in
the Change of Control Notice, or, if the Change of Control Notice is not given
as required by Section 6.4(b) at any time following the last day the Company was
required to give the Change of Control Notice in accordance with Section 6.4(b)
(in which case the Redemption Date shall be the date which is the later of (x)
30 days following the last day the Company was required to give the Change of
Control Notice in accordance with Section 6.4(b) and (y) 15 days following the
delivery of such election by such Holder), a written notice, in the form
specified by the Company (if the Company did in fact give the notice required by
Section 6.4(b)), to the Company so stating, and specifying the Debentures or
portions thereof to be redeemed pursuant to Section 6.4(a); provided, however,
that if all of the Debentures are owned by 50 or fewer Holders or groups of
Affiliated Holders, such Holders or groups may deliver a notice of an election
to redeem at any time within 90 days following the occurrence of a Change of
Control without awaiting receipt of a Change of Control Notice or the expiration
of the time allowed for the delivery of a Change of Control Notice hereunder.
The Company shall redeem the Debentures or portions thereof so specified on the
Redemption Date fixed by the Company or as provided in the preceding sentence.
The Company shall comply with the requirements of Rules 13e-4 and 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Debentures as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Section, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations hereunder by virtue thereof.


                  Section 6.5. Deposit of Redemption Price. On or prior to the
relevant Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent, as a trust fund for the benefit of the Holders of Debentures to be
redeemed, an amount of cash sufficient to pay the Redemption Price of all the
Debentures which are to be redeemed in accordance with the Notice of Redemption
or Change of Control Notice, with irrevocable instructions and authority to the
Trustee or Paying Agent (as applicable) to pay to the respective Holders, as
evidenced by a list of such Holders certified by an officer of the Company, the
Redemption Price upon surrender of their respective Debentures. Such deposit
shall be deemed to constitute full payment of such Debentures, and from and
after the date of such deposit, all rights of the Holders of Debentures that are
to be redeemed, except the right to receive the Redemption Price upon the
surrender of their respective Debentures, shall cease and terminate. After the
Redemption Date, no interest shall accrue on any Debentures to be redeemed
(unless the Company shall fail to deposit cash sufficient to redeem all such
Debentures). In case Holders of any Debentures called for redemption shall not,
within two years after such deposit, claim the cash deposited for redemption
thereof, the Trustee or Paying Agent (as applicable) shall, upon demand, pay
over to the Company the balance so deposited, or (if then held by the Company or
any of its Subsidiaries or Affiliates) such balance shall be discharged from
such trust. Thereupon, the Trustee or Paying Agent (as applicable) shall be
relieved of all responsibility to the Holders thereof, or if the Company or any
of its Subsidiaries or Affiliates acts as Paying Agent, such Paying Agent shall
be relieved of all responsibility as trustee of the cash so deposited, and the
sole right of such Holders, with respect to Debentures to be redeemed, shall be
to receive the Redemption Price as general creditors of the Company. Any
interest accrued on any funds so deposited shall belong to the Company, and
shall be paid to it from time to time on demand.

<PAGE>   33
                  Section 6.6. Debentures Payable on Redemption Date. On or
after the Redemption Date, each Holder of Debentures called for redemption shall
surrender its Debenture to the Company at the place designated in the Notice of
Redemption or Change of Control Notice and shall thereupon be entitled to
receive payment of the Redemption Price.

                  Section 6.7. Debentures Redeemed in Part. Upon surrender of a
Debenture which is to be redeemed in part in accordance with the provisions of
this Article, the Company shall execute, and the Trustee shall authenticate and
make available for delivery to the Holder of such Debenture (or to any other
Person as directed by the Holder of such Debenture) at the expense of the
Company, a new Debenture or Debentures, of any authorized denomination as
requested by such Holder, in an aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Debenture so
surrendered.

                  Section 6.8. Rating Conditions. For so long as the Investor or
an Affiliate of the Investor holds any Debentures, no Notice of Redemption in
connection with a redemption pursuant to Section 6.1 shall be delivered unless
(i) the Company's unsecured debt is rated Baa or better by Moody's or BBB or
better by S&P or (ii) the Company has sufficient funds reasonably available
under committed lines of credit or other similar sources of financing
established with financially sound financing providers to pay, on the Redemption
Date, the aggregate Redemption Price in connection with such redemption (and
shall reserve such funds or availability for the payment of the aggregate
Redemption Price); provided, that the Company may deliver a Notice of Redemption
without complying with the foregoing conditions if prior to, or
contemporaneously with, the delivery of such notice the Company irrevocably
deposits in accordance with Section 6.5 funds sufficient to pay the aggregate
Redemption Price for the Debentures.

                                   ARTICLE VII

                              DEFAULTS AND REMEDIES

                           Section 7.1. Events of Default. An "Event of Default"
shall occur if:

                  (1) the Company defaults in the payment of the principal of
         any Debenture when the same becomes due and payable at its maturity,
         upon redemption, upon required repurchase, upon declaration or
         otherwise;

                  (2) the Company defaults in the performance of or breaches any
         other covenant or agreement in this Indenture or under the Debentures
         (other than referred to in (1) above) and such default or breach
         continues for 60 days after the notice specified below;

                  (3) the Company, pursuant to or within the meaning of any
         Bankruptcy Law:

                           (A) commences a voluntary case;

                           (B) consents to the entry of an order for relief
                  against it in an involuntary case;

                                       27
<PAGE>   34
                           (C) consents to the appointment of a Custodian of it
                  or for any substantial part of its property; or

                           (D) makes a general assignment for the benefit of its
                  creditors;

                  or takes any comparable action under any foreign laws relating
                  to insolvency;

                  (4) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (A) is for relief against the Company in an
                  involuntary case;

                           (B) appoints a Custodian of the Company or for any
                  substantial part of its property; or

                           (C) orders the winding up or liquidation of the
                  Company;

                  and the order, decree or relief remains unstayed and in effect
                  for 60 days.

                  The foregoing will constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

                  Notwithstanding the foregoing, a default under clause (2) of
this Section will not constitute an Event of Default until the Trustee or the
Holders of more than 25% in aggregate principal amount of the Outstanding
Debentures deliver to the Company written notice of the default and the Company
does not cure such default within the time specified in said clause (2) after
receipt of such notice. Such notice must specify the default, demand that it be
remedied and state that such notice is a "Notice of Default."

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any default or Event of Default under clauses (2), (3) and (4) of this
Section, their status and what action the Company is taking or proposes to take
in respect thereof.


                  Section 7.2. Acceleration of Maturity; Rescission and
Annulment. If an Event of Default (other than an Event of Default specified in
Section 7.1(3) or Section 7.1(4)) occurs and is continuing, the Trustee by
written notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Outstanding Debentures by written notice to the Company
and the Trustee, may, and the Trustee at the request of such Holders shall,
declare the principal of and accrued but unpaid interest on all the Debentures
to be due and payable. Upon such a declaration, such principal and accrued and
unpaid interest shall be immediately due and payable. If an Event of Default
specified in Section 7.1(3) or Section 7.1(4) occurs, the principal of and
accrued and unpaid interest on all the Debentures will become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holders. Holders of a majority in aggregate principal amount of the then
Outstanding Debentures by written notice to the Trustee may rescind and annul an
acceleration and its consequences if the


                                       28
<PAGE>   35

rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal or interest that has become
due solely because of the acceleration) have been cured or waived.


                  Section 7.3. Other Remedies. If an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Debentures or to enforce the
performance of any provision of the Debentures or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Debentures or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.


                  Section 7.4. Waiver. The Investor and its Affiliates, so long
as such Persons own at least 20% of the aggregate principal amount of
Outstanding Debentures and subject to the TIA, or the Holders of not less than a
majority of the aggregate principal amount of Outstanding Debentures, by their
consent (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for Debentures), may waive by
written notice to the Trustee an existing default or Event of Default and its
consequences except (i) a default or Event of Default under Section 7.1(1) or an
Event of Default under Section 7.1(2) in respect of a default in the payment of
interest on the Debentures or (ii) a default or Event of Default in respect of a
provision that under Section 10.2 cannot be amended without the consent of each
Holder. Notwithstanding the preceding sentence, a waiver by the Investor and its
Affiliates of an existing default or Event of Default shall not be effective if
Holders of a majority of the aggregate principal amount of Outstanding
Debentures (i) have delivered to the Company pursuant to Section 7.1 written
notice of a default under Section 7.1(2) in respect of such default, (ii)
pursuant to Section 7.2, have declared the principal of and accrued but unpaid
interest on all Debentures to be due and payable by virtue of such Event of
Default, or (iii) give written notice to the Trustee that such Holders do not
consent to the waiver of such default or Event of Default and its consequences.
When a default or Event of Default is waived, it is deemed cured, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any consequent right.


                  Section 7.5. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in the
manner and to the extent provided in the TIA; provided, that neither this
Section nor the TIA shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company,
to any suit instituted by the Trustee, to any suit instituted by any Holder, or
group of Holders, holding in the aggregate more than 10% in principal amount of
the Debentures, or to any suit by a Holder for the enforcement of the payment of
the principal of or interest on any Debenture, on or after the respective due
dates expressed in such Debenture.

                                       29
<PAGE>   36
                  Section 7.6. Control. The Holders of a majority of the
aggregate principal amount of the Outstanding Debentures may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. Subject to
Section 8.1 and Section 8.2, however, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee
determines is unduly prejudicial to the rights of other Holders; provided,
however, that the Trustee may take any other action deemed proper by the Trustee
that is not inconsistent with such direction.

                           Section 7.7. Limitation on Suits. Subject to Section
7.8, a Holder may not pursue any remedy with respect to this Indenture or the
Debentures unless:

                           (1) the Holder gives to the Trustee written notice
         stating that an Event of Default is continuing;

                  (2) the Investor and its Affiliates, so long as such Persons
         own at least 20% of the aggregate principal amount of Outstanding
         Debentures and subject to the TIA, or the Holders of at least 25% of
         the aggregate principal amount of Outstanding Debentures make a written
         request to the Trustee to pursue the remedy;

                  (3) such Holder or Holders offer to the Trustee reasonable
         security or indemnity against any loss, liability or expense;

                  (4) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of security or
         indemnity; and

                  (5) the Investor and its Affiliates, so long as such Persons
         own at least 20% of the aggregate principal amount of Outstanding
         Debentures and subject to the TIA, or the Holders of a majority of the
         aggregate principal amount of Outstanding Debentures do not give the
         Trustee a direction that, in the opinion of the Trustee, is
         inconsistent with such request during such 60-day period, provided,
         however, that any such direction given by the Investor and its
         Affiliates shall be disregarded for all purposes of this clause (5) if
         (i) such request was made by Holders of a majority of the aggregate
         principal amount of Outstanding Debentures or (ii) such Holders give
         the Trustee a direction that, in the opinion of the Trustee, is
         inconsistent with such direction given by the Investor and its
         Affiliates;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

                  Section 7.8. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture (including, without
limitation, Sections 7.6 and 7.7) or the Debentures, the right of any Holder to
receive payment of principal of or interest on the Debentures held by such
Holder, on or after the respective due dates expressed in the Debentures (or, in
the case of redemption, on the Redemption Date), or to bring suit for the
enforcement of

                                       30
<PAGE>   37
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

                  Section 7.9. Collection Suit by Trustee. If an Event of
Default specified in Section 7.1(1) or an Event of Default specified in Section
7.1(2) in respect of a default in the payment of interest on the Debentures
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount then due
and owing (together with applicable interest, to the extent lawful) and the
amounts provided for in Section 8.7.

                  Section 7.10. Trustee May File Proofs of Claim. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Holders allowed
in any judicial proceedings relative to the Company, its Subsidiaries or its or
their respective creditors or properties and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
Custodian and shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the TIA in
order to have claims of the Holders and the Trustee allowed in any such
proceeding. Without limiting the generality of the foregoing, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same, and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.7.

                  No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Debentures or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

         Section 7.11. Priorities. If the Trustee collects any money or property
pursuant to this Article, it shall pay out the money or property in the
following order:

                  FIRST: to the Trustee for amounts due under Section 8.7;

                  SECOND: if the Holders proceed against the Company directly
         without the Trustee in accordance with this Indenture, to Holders for
         their collection costs;

                  THIRD: to Holders for amounts due and unpaid on the Debentures
         for principal and interest, ratably, without preference or priority of
         any kind, according to the amounts due and payable on the Debentures
         for principal and interest, respectively; and

                  FOURTH:  to the Company.

                                       31
<PAGE>   38
The Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section. At least 15 days before such record date, the Company
shall mail to each Holder and the Trustee a notice that states the record date,
the payment date and amount to be paid.

                                  ARTICLE VIII

                                     TRUSTEE

                  Section 8.1. Duties of Trustee. (a) If a default or an Event
of Default has occurred and is continuing, the Trustee shall exercise the rights
and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs; provided, that if an
Event of Default occurs and is continuing, the Trustee will be under no
obligation to exercise any of the rights or powers under this Indenture at the
request or direction of any of the Holders unless such Holders have offered to
the Trustee reasonable indemnity or security against loss, liability or expense.

                  (b) Except during the continuance of a default or an Event of
Default:

                  (1) the Trustee undertakes to perform such duties and
         responsibilities and only such duties and responsibilities as are
         provided by the TIA or specifically set forth in this Indenture and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of any such certificates or
         opinions which by any provisions hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine such certificates
         and opinions to determine whether or not such certificates or opinions
         conform to the requirements of this Indenture (but need not confirm or
         investigate the accuracy of mathematical calculations or other facts
         stated therein).

                  (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                  (1) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (2) the Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 7.2, Section 7.4 or Section 7.5.

                  (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

                                       32
<PAGE>   39
                  (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

                  (f) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

                  (g) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

                  (h) Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

                  (i) Unless otherwise specifically provided in this Indenture,
any demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

                  (j) The Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders unless such Holders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

                  Section 8.2. Rights of Trustee. (a) Subject to Section 8.1,
the Trustee may rely on any document reasonably believed by it to be genuine and
to have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
an Officers' Certificate or Opinion of Counsel.

                  (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent appointed
with due care.

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Trustee's conduct does not
constitute willful misconduct or negligence.

                  (e) The Trustee may consult with counsel of its selection, and
the advice or Opinion of Counsel with respect to legal matters relating to this
Indenture and the Debentures shall be full and complete authorization and
protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

                  Section 8.3. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Debentures
and may otherwise deal with the

                                       33
<PAGE>   40
Company or its Affiliates with the same rights it would have if it were not
Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the
same with like rights. However, the Trustee must comply with Section 8.10 and
Section 8.11.

                  Section 8.4. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Debentures, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Debentures or in the Debentures other than the
Trustee's certificate of authentication.

                  Section 8.5. Notice of Defaults. If a default or Event of
Default occurs and is continuing and if a Trust Officer has knowledge thereof,
the Trustee shall mail to each Holder notice of the default or Event of Default
as and to the extent provided by the TIA within 30 days after it is known to a
Trust Officer or written notice of it is received by the Trustee. Except in the
case of a default or Event of Default in payment of principal of or interest on
any Debenture (including payments pursuant to the optional redemption or
required repurchase provisions of such Debenture, if any), the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is not opposed to the interests of
the Holders.

                  Section 8.6. Reports by Trustee to Holders. The Trustee shall
comply with TIA Section 313. The Company agrees to notify promptly the Trustee
whenever the Debentures become listed on any stock exchange and of any delisting
thereof.

                  Section 8.7. Compensation and Indemnity. (a) The Company shall
pay to the Trustee from time to time reasonable compensation for its acceptance
of this Indenture and services hereunder as the Company and the Trustee shall
from time to time agree in writing. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, costs of preparing and reviewing reports,
certificates and other documents, costs of preparation and mailing of notices to
Holders and reasonable costs of counsel retained by the Trustee in connection
with the delivery of an Opinion of Counsel or otherwise, in addition to the
compensation for its services, except any such expense as may be attributable to
its negligence or bad faith. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts.

                  (b) The Company shall jointly and severally indemnify the
Trustee against any and all losses, liabilities or expenses (including
reasonable attorneys' fees and expenses) incurred by it, without negligence or
bad faith on its part, in connection with the administration of this trust and
the performance of its duties hereunder, including the costs and expenses of
enforcing this Indenture (including this Section) and of defending itself
against any claims (whether asserted by any Holder, the Company or otherwise).
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable fees and expenses of such counsel
provided that the Company shall not be required to pay such fees and expenses if
it assumes the Trustee's defense,

                                       34
<PAGE>   41
and, in the reasonable judgment of outside counsel to the Trustee, there is no
conflict of interest between the Company and the Trustee in connection with such
defense. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee's own
willful misconduct, negligence or bad faith. The Company need not pay for any
settlement made without its consent.

                  (c) To secure the Company's payment obligations in this
Section, the Trustee shall have a lien prior to the Debentures on all money or
property held or collected by the Trustee other than money or property held in
trust to pay principal of and interest on particular Debentures. The Trustee's
right to receive payment of any amounts due under this Section shall not be
subordinate to any other liability or Indebtedness of the Company.

                  (d) The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture. When the Trustee incurs expenses
after the occurrence of a default specified in Section 7.1(3) or Section 7.1(4)
with respect to the Company, the expenses are intended to constitute expenses of
administration under any Bankruptcy Law; provided, however, that this shall not
affect the Trustee's rights as set forth in this Section or Section 7.10.

                  Section 8.8. Replacement of Trustee. (a) A resignation or
removal of the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee's acceptance of appointment as
provided in this Section.

                  (b) The Trustee may resign at any time by giving written
notice thereof to the Company. The Investor and its Affiliates, so long as such
Persons own at least 20% of the aggregate principal amount of the Outstanding
Debentures, or the Holders of a majority of the aggregate principal amount of
the Outstanding Debentures may remove the Trustee by giving written notice
thereof to the Trustee and may appoint a successor Trustee. The Company shall
remove the Trustee if:

                  (1)  the Trustee fails to comply with Section 8.10;

                  (2) the Trustee is adjudged bankrupt or insolvent or an order
                  for relief is entered with respect to the Trustee under any
                  Bankruptcy law;

                  (3) a receiver or other public officer takes charge of the
                  Trustee or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  (c) If the Trustee resigns or is removed by the Company, by
the Investor and its Affiliates or by Holders of Debentures in accordance with
this Indenture, and the Investor and its Affiliates or such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of the Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

                  (d) A successor Trustee shall execute, acknowledge and deliver
a written acceptance of its appointment to the retiring Trustee and to the
Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee

                                       35
<PAGE>   42
shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section
8.7.

                  (e) If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Investor and its Affiliates, so long as such Persons own at least 20% of the
aggregate principal amount of the Outstanding Debentures, or the Holders of 10%
of the aggregate principal amount of the Outstanding Debentures may petition, at
the Company's expense, any court of competent jurisdiction for the appointment
of a successor Trustee.

                  (f) If the Trustee fails to comply with Section 8.10, any
Holder who has been a Holder of a Debenture for at least six months may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

                  (g) Notwithstanding the replacement of the Trustee pursuant to
this Section, the Company's obligations under Section 8.7 shall continue for the
benefit of the retiring Trustee.

                  Section 8.9. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                  In case at the time such successor or successors shall succeed
to the trusts created by this Indenture, any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such
Debentures so authenticated; and in case at that time any of the Debentures
shall not have been authenticated, any successor to the Trustee may authenticate
such Debentures either in the name of any predecessor hereunder or in the name
of the successor to the Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Debentures or in this Indenture
provided that the certificate of the Trustee shall have.

                  Section 8.10. Eligibility; Disqualification. There shall at
all times be a Trustee hereunder that is a corporation organized and doing
business under the laws of the United States of America or of any state thereof
that is authorized under such laws to exercise corporate trust powers, and that
is subject to supervision or examination by federal or state authorities. The
Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Trustee shall have a combined capital and surplus of at least $500 million as
set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures
under which other securities or certificates of interest or participation in
other securities of the Company are Outstanding if the requirements for such
exclusion set forth in TIA Section 310(b)(1) are met.

                  Section 8.11. Preferential Collection of Claims Against

                     SATISFACTION AND DISCHARGE OF INDENTURE

                  Section 9.1.  Termination of the Company's Obligations.

                  This Indenture will be satisfied and discharged and will cease
to be of further effect (except as to surviving rights of registration of
transfer or exchange of the Debentures and except as to compensation and
indemnity to the Trustee, as expressly provided for below) as to all Outstanding
Debentures when:

                  (a) either (i) all the Debentures theretofore authenticated
         and delivered (except lost, stolen or destroyed Debentures which have
         been replaced or paid as provided in Section 2.8 and Debentures for
         whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Company and thereafter repaid to
         the Company or discharged from such trust as provided in Section 2.5)
         have been delivered to the Trustee for cancellation or (ii) all
         Debentures not theretofore delivered to the Trustee for cancellation
         have become due and payable and the Company thereafter has irrevocably
         deposited or caused to be deposited with the Trustee funds in an amount
         sufficient to pay and discharge the entire Indebtedness on the
         Debentures not theretofore delivered to the Trustee for cancellation,
         for principal of and interest on the Debentures to the date of deposit
         together with irrevocable instructions from the Company directing the
         Trustee to apply such funds to the payment thereof;

                  (b) no default or Event of Default with respect to this
         Indenture or the Debentures shall have occurred and be continuing on
         the date of such deposit or shall occur as a result of such deposit and
         such deposit will not result in a breach or violation of, or constitute
         a default under, any other instrument to which the Company is a party
         or by which it is bound;

                  (c) the Company shall have paid all other sums payable by it
         hereunder or under the Debentures; and

                  (d) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent providing for the termination of the Company's
         obligations under the Debentures and this Indenture have been complied
         with. Such Opinion of Counsel shall also state that such satisfaction
         and discharge does not result in a default under any instrument
         evidencing debt senior to the Debentures or any other agreement or
         instrument then known to such counsel that binds or affects the
         Company.

                  Notwithstanding the foregoing paragraph, the Company's
obligations in Sections 2.6, 2.7, 2.9, 2.10 and 8.7 shall survive until the
Debentures are no longer Outstanding. After the Debentures are no longer
Outstanding, the Company's obligations in Section 8.7 shall survive.

<PAGE>   44
                  After such delivery or irrevocable deposit, the Trustee upon
request shall acknowledge in writing the satisfaction and discharge of the
Company's obligations under the Debentures and this Indenture except for those
surviving obligations specified above.

                           AMENDMENTS AND SUPPLEMENTS

                  Section 10.1. Without Consent of Holders. (a) Notwithstanding
Section 10.2, the Company and the Trustee, in accordance with this Article, may
amend or supplement this Indenture or the Debentures without notice to or
consent of any Holder:

                  (1)  to cure any ambiguity or inconsistency;

                  (2) to comply with Article V in respect of the assumption by a
         Successor Company of an obligation of the Company under this Indenture;

                  (3) to provide for uncertificated Debentures in addition to or
         in place of certificated Debentures; provided, however, that the
         uncertificated Debentures are issued in registered form for purposes of
         Section 163(f) of the Code or in a manner such that the uncertificated
         Debentures are described in Section 163(f)(2)(B) of the Code;

                  (4) to add guarantees with respect to the Debentures or to
         secure the Debentures;

                  (5) to add to the covenants of the Company for the benefit of
         the Holders or to surrender any right or power herein conferred upon
         the Company; or

                  (6) to comply with any requirements of the SEC in connection
         with qualifying this Indenture under the TIA or to provide for the
         succession of a successor Trustee in accordance with the terms hereof
         prior to such amendment or supplement;

provided, that any such change does not adversely affect the rights of any
Holder in any material respect.

                  Section 10.2. With Consent of Holders. The Company, and the
Trustee may amend or supplement this Indenture or the Debentures without notice
to any Holder but with the written consent of the Holders of at least a majority
of the aggregate principal amount of the Outstanding Debentures (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Debentures). However, without the consent of
each Holder affected, an amendment or supplemental Indenture may not:

                  (1) reduce the percentage in principal amount of the
         Outstanding Debentures whose Holders must consent to an amendment,
         supplement or waiver;

                  (2) reduce the rate of or change or have the effect of
         changing the time for payment of interest on any Debentures;



                                       38
<PAGE>   45

                   (3) reduce the principal of or change or have the effect of
         changing the fixed maturity of any Debentures, or change the date on
         which any Debentures may be subject to redemption, or reduce the
         Redemption Price therefor;

                  (4) make any Debentures payable in money other than that
         stated in the Debentures;

                  (5) make any change in the provisions of this Indenture
         entitling each Holder to receive payment of principal of and interest
         on such Debentures on or after the due date thereof or to bring suit to
         enforce such payment, or permitting Holders of a majority of the
         aggregate principal amount of Outstanding Debentures as set forth
         herein on the Issue Date to waive defaults or Events of Default; or

                  (6) amend, change or modify in a manner that would adversely
         affect the interests of the Holders in any respect, the obligation of
         the Company to redeem Debentures if a Change of Control occurs.

                  It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

                  Section 10.3. Compliance with Trust Indenture Act. Every
amendment or supplement to this Indenture or the Debentures shall comply with
the TIA as then in effect.

                  Section 10.4. Amended or Supplemental Indenture. (a) Upon the
request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental Indenture pursuant
to Section 10.1 or Section 10.2, upon receipt by the Trustee of an Officer's
Certificate or an Opinion of Counsel, which it reasonably believes to be genuine
and to have been signed or presented by the proper Person, and, in the case of
an amendment of supplement pursuant to Section 10.2, upon the filing with the
Trustee of the consent of Holders of Debentures as described in Section 10.2,
the Trustee shall join with the Company in the execution of such amended or
supplemental Indenture, unless such amended or supplemental Indenture affects
the Trustee's own rights, duties or immunities under this Indenture or otherwise
in a manner adverse to it, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture. In
signing such amended or supplemental Indenture the Trustee shall be entitled to
receive indemnity reasonably satisfactory to it and to receive, and (subject to
Section 8.1 and Section 8.2) shall be fully protected in relying upon, such
evidence as it deems appropriate, including, without limitation, solely on an
Opinion of Counsel stating that such amendment or supplemental Indenture is
authorized or permitted by this Indenture.

                  (b) After an amended or supplemental Indenture under this
Section becomes effective, the Company shall mail to Holders a notice briefly
describing such amended or supplemental Indenture. The failure to give such
notice to all Holders, or any defect therein, shall not impair or affect the
validity of an amended or supplemental Indenture under this Section.

                                       39
<PAGE>   46
                  Section 10.5. Revocation and Effect of Consents and Waivers. A
consent to an amendment, supplement or a waiver by a Holder of a Debenture shall
bind the Holder and every subsequent Holder of that Debenture or portion of the
Debenture that evidences the same debt as the consenting Holder's Debenture,
even if notation of the consent or waiver is not made on the Debenture. However,
any such Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Debenture or portion of the Debenture if the Trustee receives the
written notice of revocation before the date the amendment, supplement or waiver
becomes effective. After an amendment, supplement or waiver becomes effective,
it shall bind every Holder. An amendment, supplement or waiver shall become
effective upon receipt by the Trustee of the requisite number of written
consents under Section 10.2.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 90
days after such record date.

                  Section 10.6. Notation on or Exchange of Debentures. If an
amendment or supplement changes the terms of a Debenture, the Trustee may
require the Holder of the Debenture to deliver it to the Trustee. The Trustee
may place an appropriate notation on the Debenture regarding the changed terms
and return it to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Debenture shall issue and the
Trustee shall authenticate a new Debenture that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Debenture shall not
affect the validity of such amendment or supplement.

                                   ARTICLE XI

                         SUBORDINATION OF THE DEBENTURES

                  Section 11.1. Agreement to Subordinate. The Company agrees,
and each Holder by accepting a Debenture agrees, that the Indebtedness evidenced
by the Debentures is subordinated in right of payment, to the extent and in the
manner provided in this Article, to the prior payment in full of all Senior
Indebtedness of the Company and that the subordination is for the benefit of and
enforceable by the holders of such Senior Indebtedness. Only Senior Indebtedness
of the Company shall rank senior to the Debentures in accordance with the
provisions set forth herein, and the Debentures shall in all respects rank pari
passu with, or be senior to, all other Indebtedness of the Company. The
Debentures shall in all respects rank pari passu with, and not senior to, any
Series E Debentures. All provisions of this Article shall be subject to Section
11.12.

                  Section 11.2. Liquidation, Dissolution, Bankruptcy. Upon any
payment or distribution of the assets of the Company to creditors upon a total


                                       40
<PAGE>   47
or partial liquidation or a total or partial dissolution of the Company or in a
winding up or bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property:

                  (1) holders of Senior Indebtedness of the Company shall be
entitled to receive payment in full of such Senior Indebtedness before Holders
of the Debentures shall be entitled to receive any payment of principal of or
interest on the Debentures; and

                  (2) until such Senior Indebtedness is paid in full, any
distribution to which Holders would be entitled but for this Article shall be
made to holders of such Senior Indebtedness as their interests may appear,
except that Holders may receive (a) securities of a Person that are subordinated
("Subordinated Reorganization Securities") to such Senior Indebtedness to at
least the same extent as the Debentures are subordinated to (A) Senior
Indebtedness of the Company and (B) any Indebtedness or securities issued in
exchange for Senior Indebtedness, and (b) payments and other distributions made
from any funds deposited by the Company pursuant to Section 9.1.

                  Section 11.3. Default on Senior Indebtedness of the Company.
The Company may not pay the principal of or interest on the Debentures or make
any deposit pursuant to Section 9.1 and may not repurchase, redeem or otherwise
retire any Debentures (collectively, "pay the Debentures") (other than in the
form of Subordinated Reorganization Securities and payments and other
distributions made from any funds deposited by the Company pursuant to Section
9.1) if (i) any Senior Indebtedness of the Company is not paid when due or (ii)
any other default on such Senior Indebtedness occurs and the maturity of such
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, (x) the default has been cured or waived and any such acceleration
has been rescinded or (y) such Senior Indebtedness has been paid in full;
provided, however, that the Company may pay the Debentures without regard to the
foregoing if the Company and the Trustee receive written notice approving such
payment from the representative of such Senior Indebtedness with respect to
which either of the events set forth in clause (i) or (ii) of this sentence has
occurred and is continuing. During the continuance of any default (other than a
default described in clause (i) or (ii) of the preceding sentence) with respect
to any Senior Indebtedness of the Company pursuant to which the maturity thereof
may be accelerated immediately without further notice (except such notice as may
be required to effect such acceleration) or the expiration of any applicable
grace periods, the Company may not pay the Debentures for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
representative of the holders of such Senior Indebtedness specifying an election
to effect a Payment Blockage Period and ending 179 days thereafter (or earlier
if such Payment Blockage Period is terminated (i) by written notice to the
Trustee and the Company from the Person or Persons who gave such Blockage
Notice, (ii) because the default giving rise to such Blockage Notice is no
longer continuing or (iii) because such Senior Indebtedness has been repaid in
full). Notwithstanding the provisions of the immediately preceding sentence (but
subject to the provisions of the first sentence of this Section), unless the
holders of such Senior Indebtedness or the representative of such holders have
accelerated the maturity of such Senior Indebtedness, the Company may resume
payments on the Debentures after such Payment Blockage Period. The Debentures
shall not be subject to more than one Payment Blockage Period in any consecutive
360-day period, irrespective of the number of defaults with respect to Senior
Indebtedness during such period. For purposes of this Section, no default or
event of


                                       41
<PAGE>   48
default with respect to the Senior Indebtedness and which existed or was
continuing on the date of the commencement of any Payment Blockage Period and
which initiated such Payment Blockage Period shall be, or be made, the basis of
the commencement of a subsequent Payment Blockage Period by the representative
of such Senior Indebtedness, whether or not within a period of 360 consecutive
days, unless such default or event of default shall have been cured or waived
for a period of not less than 90 consecutive days.

                  Section 11.4. Acceleration of Payment of Debentures. If
payment of the Debentures is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of the Senior
Indebtedness of the Company (or their representative) of the acceleration.

                  Section 11.5. When Distribution Must Be Paid Over. If a
distribution is made to Holders that because of this Article should not have
been made to them, the Holders who receive the distribution shall hold it in
trust for holders of Senior Indebtedness of the Company and pay it over to them
as their interests may appear.

                  Section 11.6. Subrogation. After all Senior Indebtedness of
the Company is paid in full and until the Debentures are paid in full, Holders
shall be subrogated to the rights of holders of such Senior Indebtedness to
receive distributions applicable to such Senior Indebtedness. A distribution
made under this Article to holders of such Senior Indebtedness which otherwise
would have been made to Holders is not, as between the Company and Holders, a
payment by the Company on such Senior Indebtedness.

                  Section 11.7. Relative Rights. This Article defines the
relative rights of Holders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall:

                  (1) impair, as between the Company and Holders, the obligation
of the Company, which is absolute and unconditional, to pay principal of and
interest on the Debentures in accordance with their terms; or


                  (2) prevent the Trustee or any Holder from exercising its
available remedies upon a default in respect of the Debentures (including,
without limitation, the remedies set forth in Article IV), subject to the
rights, if any, of holders of Senior Indebtedness of the Company to receive
distributions otherwise payable to Holders.


                  Section 11.8. Subordination May Not Be Impaired by Company. No
right of any holder of Senior Indebtedness of the Company to enforce the
subordination of the Indebtedness evidenced by the Debentures shall be impaired
by any act or failure to act by the Company or by its failure to comply with
this Indenture.

                  Section 11.9. Rights of Trustee and Paying Agent.
Notwithstanding Section 11.3, the Trustee or Paying Agent may continue to make
payments on the Debentures and shall not be charged with knowledge of the
existence of facts that would prohibit the making of any such payments unless,
not less than two Business Days prior to the date of such payment, a Trust
Officer of the Trustee receives written notice satisfactory to it that payments
may not be made under this Article. The Company, the Registrar or co-registrar,
the Paying Agent, a representative or a holder of Senior Indebtedness may give
such notice; provided, however, that,


                                       42
<PAGE>   49
if the holders of an issue of Senior Indebtedness of the Company have a
representative, only the representative may give such notice.

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness of the Company with the same rights it would have if it were
not Trustee. The Registrar and co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article with respect to any Senior Indebtedness of the Company which may at
any time be held by it, to the same extent as any other holder of such Senior
Indebtedness, and nothing in Article VII shall deprive the Trustee of any of its
rights as such holder. Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 8.7.

                  Section 11.10. Distribution or Notice to Representative.
Whenever a distribution is to be made or a notice given to holders of Senior
Indebtedness of the Company, the distribution may be made and the notice given
to their representative (if any).

                  Section 11.11. Article XI Not to Prevent Events of Default or
Limit Right to Accelerate. The failure to make a payment pursuant to the
Debentures by reason of any provision in this Article shall not be construed as
preventing the occurrence of a default in respect of the Debentures. Nothing in
this Article shall have any effect on the right of the Holders or the Trustee to
accelerate the maturity of the Debentures.

                  Section 11.12. Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money held in trust
under Article IX by the Trustee for the payment of principal of and interest on
the Debentures shall not be subordinated to the prior payment of any Senior
Indebtedness or subject to the restrictions set forth in this Article, and none
of the Holders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness of the Company or any other creditor of the
Company.

                  Section 11.13. Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article, the Trustee and the Holders shall be
entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 11.2
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Holders or (iii) upon the representative for the holders of Senior Indebtedness
of the Company for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of such Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of the Company to participate
in any payment or distribution pursuant to this Article, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of such Senior Indebtedness held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
other facts pertinent to the rights of such Person under this Article, and, if
such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such


                                       43
<PAGE>   50
payment. The provisions of Section 8.1 and Section 8.2 shall be applicable to
all actions or omissions of actions by the Trustee pursuant to this Article.

                  Section 11.14. Trustee to Effectuate Subordination. Each
Holder by accepting a Debenture authorizes and directs the Trustee on such
Holder's behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Holders and the holders
of Senior Indebtedness of the Company as provided in this Article and appoints
the Trustee as attorney-in-fact for any and all such purposes.

                  Section 11.15. Trustee Not Fiduciary for Holders of Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Holders or the Company or any other
Person, money or assets to which any holders of Senior Indebtedness of the
Company shall be entitled by virtue of this Article or otherwise.

                  Section 11.16. Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Holder by accepting a Debenture acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration to each holder of any Senior Indebtedness of
the Company, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Debentures, to acquire and continue to hold such
Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed
conclusively to have relied on such subordination provisions in acquiring and
continuing to hold such Senior Indebtedness.

                                   ARTICLE XII

                                  MISCELLANEOUS

                  Section 12.1. Trust Indenture Act Controls. If any provision
of this Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the TIA, the provision required by
the TIA shall control. If any provision of this Indenture modifies or excludes
any provision of the TIA that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

                  Section 12.2. Notices. Any notice or communication shall be in
writing and delivered in person or mailed by first class mail, postage prepaid,
telecopier or overnight air courier guaranteeing next day delivery addressed as

                        FORM OF REVERSE SIDE OF DEBENTURE

            Series D Junior Subordinated Debentures Due May 13, 2008

1.       Interest


                  Oxford Health Plans, Inc., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), for value received promises to
pay interest on the principal amount of this Debenture quarterly on the last day
of March, June, September and December (and, if such date is a Legal Holiday,
the Business Day next succeeding such day) at a rate of 5.129810% per annum.
Interest on the Debentures will accrue from the most recent date to which
interest has been paid on the Debentures or, if no interest has been paid, from
the Issue Date. The Company shall pay interest on overdue principal (plus
interest on such interest to the extent lawful), at the rate borne by the
Debentures to the extent lawful.


2.       Method of Payment

                  By at latest 10:00 a.m. (New York City time) on the date on
which any principal of or interest on any Debenture is due and payable, the
Company shall irrevocably deposit with the Trustee or the Paying Agent money
sufficient to pay such principal and/or interest. The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of
Debentures at the close of business on the fifteenth day preceding the relevant
interest payment date (the "Record Date") even if Debentures are canceled,
repurchased or redeemed after the Record Date and on or before the interest
payment date. Holders must surrender Debentures to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. The Company will make all payments in respect of a Debenture
(including principal and interest) by mailing a check to the registered address
of each Holder thereof; provided, however, that payments on the Debentures may
also be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Debentures, by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 2 Business Days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

3.       Paying Agent and Registrar

                  Initially, [___] (the "Trustee," which term includes any
successor trustee under the Indenture), will act as Trustee, Paying Agent and
Registrar. The Company may appoint and change any Paying Agent, Registrar or
co-registrar without notice to any Holder. The Company may act as Registrar or
co-registrar or Paying Agent.

4.       Indenture

                  The Company issued the Debentures under an Indenture, dated as
of [____] (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the "Indenture"), among the Company and the Trustee. The
terms of the Debentures include those


                                      A-3
<PAGE>   58

stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect
on the date of the Indenture (the "Act"). Capitalized terms used herein and not
defined herein have the meanings ascribed thereto in the Indenture. The
Debentures are subject to all such terms, and Holders are referred to the
Indenture and the Act for a statement of those terms. Each Holder by accepting a
Debenture agrees to be bound by all of the terms and provisions of the
Indenture, as amended or supplemented from time to time.


                  The Debentures are general unsecured senior obligations of the
Company limited to $[ ] in aggregate principal amount (subject to Section 2.7,
Section 2.8, Section 2.9, Section 6.7 and Section 10.6 of the Indenture).

5.       Change of Control and Optional Redemption

                  In the event of a Change of Control, any Holder may require
the Company to redeem any or all of the Debentures held by such Holder, in
accordance with the redemption procedures set forth in Article VI of the
Indenture, at 100% of principal amount, plus accrued and unpaid interest
(including Defaulted Interest) to the redemption date (the "Redemption Price")
(subject to the right of Holders of record on the relevant Record Date to
receive interest due on the relevant interest payment date). In the event of any
redemption of Debentures in part, a new Debenture or Debentures for the
unredeemed portion of the principal of the Debenture redeemed in part will be
issued upon cancellation of the Debenture surrendered.

                  On and after May 13, 2003, the Debentures are redeemable by
the Company, in accordance with the redemption procedures set forth in Article
VI of the Indenture, in whole but not in part, at the Redemption Price.

6.       Denominations; Transfer; Exchange

                  The Debentures are in registered form without coupons in
denominations of principal amount of $1,000 and integral multiples of $1,000. A
Holder may transfer or exchange Debentures in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar shall not be required to register
the transfer of or exchange any Debenture to be redeemed, in whole or in part,
upon a change of control, except the unredeemed portion of any Debenture being
redeemed in part.

7.       Subordination

                  The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate in right of payment to the prior payment
in full of all Senior Indebtedness of the Company, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Debenture, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.

                                      A-4
<PAGE>   59
8.       Persons Deemed Owners

                  The registered holder of this Debenture may be treated as the
owner of it for all purposes.

9.       Unclaimed Money

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

10.      Discharge Prior to Redemption

                  Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Debentures and the Indenture if the Company deposits with the Trustee money for
the payment of principal and interest on the Debentures to redemption or
maturity, as the case may be.

11.      Amendment, Supplement or Waiver

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Debentures may be amended or supplemented with the written
consent of the Holders of at least a majority of the aggregate principal amount
of the Outstanding Debentures and (ii) any existing default or Event of Default
and its consequence (other than with respect to nonpayment or in respect of a
provision that cannot be amended without the written consent of each Holder
affected) may be waived with the written consent of the Investor and its
Affiliates (so long as such Persons own at least 20% of the aggregate principal
amount of Outstanding Debentures and subject to the TIA) or Holders of a
majority of the aggregate principal amount of the Outstanding Debentures.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Holder, the Company and the Trustee may amend or supplement the Indenture or
the Debentures to, among other things, cure any ambiguity or inconsistency, or
to comply with Article V of the Indenture, or to provide for uncertificated
Debentures in addition to or in place of certificated Debentures, or to add
guarantees with respect to the Debentures or to secure the Debentures, or to add
additional covenants of, or surrender rights and powers conferred on, the
Company, or to comply with any request of the SEC in connection with qualifying
the Indenture under the Act, or to provide for the succession of a successor
trustee in accordance with the terms of the Indenture prior to such amendment or
supplements, provided that any such change that does not adversely affect the
rights of any Holder in any material respect.

12.      Defaults and Remedies

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Debentures may declare
all the Debentures to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the
Debentures being due and payable immediately upon the occurrence of such Events
of Default.

                                      A-5
<PAGE>   60
                  Holders may not enforce the Indenture or the Debentures except
as provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Debentures unless it receives reasonable indemnity or security. The Trustee
may withhold from Holders notice of any continuing default or Event of Default
(except a default or Event of Default in payment of principal or interest) if it
determines that withholding notice is in their interest.

13.      Trustee Dealings with the Company

                  Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Debentures and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

14.      No Recourse Against Others

                  An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Debentures, the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By

waiver and release are part of the consideration for the issue of the
Debentures.

manually signs the certificate of authentication on the other side of this
Debenture.

                  Customary abbreviations may be used in the name of a Holder or

17.      CUSIP Numbers

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Debentures and has directed the Trustee to use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Debentures
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

accordance with, the laws of the State of New York.

form of which is annexed hereto as Exhibit A, shall constitute, and are hereby
expressly made, a part of this Indenture and, to the extent applicable, the
Company and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. The
Debentures may have such other notations, legends or endorsements as are
required by law,


                                       8
<PAGE>   15
stock exchange rule or usage. The Company and the Trustee shall approve the form
of the Debentures and any notation, legend or endorsement on them. Each
Debenture shall be dated the date of its authentication.

                  (c) The Debentures shall be issuable only in fully registered
form, without coupons. The Debentures may be issued in any denomination;
provided, however, to the extent possible Debentures will be issued in
denominations of $1,000 and integral multiples thereof.

                  (d) The Debentures are transferable only in denominations of
$1,000 and integral multiples of $1,000; provided, however, that, if the
aggregate amount of Debentures that a Holder wishes to transfer is not equal to
$1,000 or an integral multiple thereof, such Holder may transfer one Debenture
in a denomination less than $1,000.

                  Section 2.2. Global Debentures. This section shall apply only
to Global Debentures deposited with or on behalf of the Depositary.

                  (a) Each Global Debenture authenticated under this Indenture
shall be registered in the name of the Depositary designated by the Company for
such Global Debenture or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Debenture shall
constitute a single Debenture for all purposes of this Indenture.

                  (b) Notwithstanding any other provision in this Indenture, no
Global Debenture may be exchanged in whole or in part for Debentures registered,
and no transfer of a Global Debenture in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Debentures or a
nominee thereof unless (i) such Depositary (A) has notified the Company that it
is unwilling or unable to continue as Depositary for such Global Debentures or
(B) has ceased to be a clearing agency registered as such under the Exchange
Act, and in either case the Company fails to appoint a successor Depositary
within 90 days, (ii) the Company executes and delivers to the Trustee a Company
Order (as defined below) stating that it elects to cause the issuance of the
Debentures in certificated form and that all Global Debentures shall be
exchanged in whole for Debentures that are not Global Debentures (in which case
such exchange shall be effected by the Trustee) or (iii) there shall have
occurred and be continuing an Event of Default or any event which after notice
or lapse of time or both would be an Event of Default with respect to the
Debentures.

                  (c) If any Global Debenture is to be exchanged for other
Debentures or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Registrar, for exchange or
cancellation as provided in this Article. If any Global Debenture is to be
exchanged for other Debentures or canceled in part, or if another Debenture is
to be exchanged in whole or in part for a beneficial interest in any Global
Debenture, then either (i) such Global Debenture shall be so surrendered for
exchange or cancellation as provided in this Article or (ii) the principal
amount thereof shall be reduced or increased by an amount equal to the portion
thereof to be so exchanged or canceled, or equal to the principal amount of such
other Debenture to be so exchanged for a beneficial interest therein, as the
case may be, by means of an appropriate adjustment made on the records of the
Trustee, as Registrar, whereupon the Trustee, in accordance with the Applicable
Procedures, shall instruct the Depositary or its


                                       9
<PAGE>   16
authorized representative to make a corresponding adjustment to its records.
Upon any such surrender or adjustment of a Global Debenture, the Trustee shall,
as otherwise provided in this Article, authenticate and deliver any Debentures
issuable in exchange for such Global Debenture (or any portion thereof) to or
upon the order of the Company, and registered in such names as may be directed
by, the Depositary or its authorized representative. Upon the request of the
Trustee in connection with the occurrence of any of the events specified in the
preceding paragraph, the Company shall promptly make available to the Trustee a
reasonable supply of Debentures that are not in the form of Global Debentures.
The Trustee shall be entitled to rely upon any order, direction or request of
the Depositary or its authorized representative which is given or made pursuant
to this Article if such order, direction or request is given or made in
accordance with the Applicable Procedures.

                  (d) Every Debenture authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
Debenture or any portion thereof, whether pursuant to this Article or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Debenture, unless such Debenture is registered in the name of a Person other
than the Depositary for such Global Debenture or a nominee thereof.

                  (e) The Depositary or its nominee, as registered owner of a
Global Debenture, shall be the Holder of such Global Debenture for all purposes
under this Indenture and the Debentures, and owners of beneficial interests in a
Global Debenture shall hold such interests pursuant to the Applicable
Procedures. Accordingly, any such owner's beneficial interest in a Global
Debenture will be shown only on, and the transfer of such interest shall be
effected only through, records maintained by the Depositary or its nominee or
its Agent Members.

                  Section 2.3. Execution and Authentication. (a) Two Officers,
one of whom shall be the Chairman of the Board, the President, the Chief
Executive Officer or the Chief Financial Officer of the Company, shall sign the
Debentures for the Company by manual or facsimile signature. If an Officer whose
signature is on a Debenture no longer holds that office at the time the Trustee
authenticates the Debenture, the Debenture shall be valid nevertheless.

                  (b) A Debenture shall not be valid until an authorized
signatory of the Trustee authenticates the Debenture. The signature of the
Trustee on a Debenture shall be conclusive evidence that such Debenture has been
duly and validly authenticated and issued under this Indenture. The form of
Trustee's certificate of authentication to be borne by the Debentures shall be
substantially as set forth in Exhibit A hereto.

                  (c) At any time and from time to time after the execution and
delivery of this Indenture, the Trustee shall authenticate and make available
for delivery Debentures for original issue on the Issue Date in an aggregate
principal amount not to exceed $[ ], upon a written order of the Company signed
by two Officers of the Company (a "Company Order"). Such Company Order shall
specify the amount of the Debentures to be authenticated and the date on which
the original issue of Debentures is to be authenticated. Except as expressly set
forth in Article IV, all Debentures issued under this Indenture shall vote and
consent together on all matters as one class.


                                       10
<PAGE>   17
             (d) The Trustee may appoint an agent (the "Authenticating Agent")
reasonably acceptable to the Company to authenticate the Debentures. Unless
limited by the terms of such appointment, any such Authenticating Agent may
authenticate Debentures whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by the
Authenticating Agent.

            (e) In case the Company, pursuant to Article V, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of its properties and assets substantially as an
entirety to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have
been merged, or the Person which shall have received a conveyance, transfer,
lease or other disposition as aforesaid, shall have executed an indenture
supplemental hereto with the Trustee pursuant to Article V, any of the
Debentures authenticated or delivered prior to such consolidation, merger,
conveyance, transfer, lease or other disposition may, from time to time, at the
request of the successor Person, be exchanged for other Debentures executed in
the name of the successor Person with such changes in phraseology and form as
may be appropriate, but otherwise in substance of like tenor as the Debentures
surrendered for such exchange and of like principal amount, and the Trustee,
upon Company Order of the successor Person, shall authenticate and deliver
Debentures as specified in such order for the purpose of such exchange. If
Debentures shall at any time be authenticated and delivered in any new name of a
successor Person pursuant to this Section in exchange or substitution for or
upon registration of transfer of any Debentures, such successor Person, at the
option of the Holders but without expense to them, shall provide for the
exchange of all Debentures at the time Outstanding for Debentures authenticated
and delivered in such new name.

            Section 2.4. Registrar and Paying Agent. (a) The Company shall
maintain an office or agency in the Borough of Manhattan, City of New York,
where Debentures may be presented for registration of transfer or for exchange
(the "Registrar"), where Debentures may be presented for payment (the "Paying
Agent") and for the service of notices and demands to or upon the Company in
respect of the Debentures and this Indenture. The Registrar shall keep a
register of the Debentures and of their transfer and exchange (the "Debenture
Register"). The Company may have one or more co-registrars and one or more
additional paying agents. The term "Paying Agent" includes any additional paying
agent.

            (b) The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 8.7. The
Company may act as Registrar, Paying Agent, co-registrar or transfer agent.

            (c) The Company initially appoints the Trustee at its principal
corporate trust office in the Borough of Manhattan, City of New York (the
"Corporate Trust Office") as Registrar, Paying Agent and agent for service of
demands and notices in connection with the Debentures and this Indenture, and as
Custodian with respect to the Global Debentures, until such time as the Trustee
has resigned or a successor Trustee has been appointed.


                                       11
<PAGE>   18
            (d) The Company initially appoints DTC to act as Depositary with
respect to the Global Debentures.

            Section 2.5. Deposit of Monies; Paying Agent to Hold Money in Trust.
(a) By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Debenture is due and payable, the Company shall
deposit with the Paying Agent in immediately available funds money sufficient to
pay such principal or interest when due.

            (b) The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that such Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by such Paying Agent for the
payment of principal of or interest on the Debentures and shall notify the
Trustee in writing of any default by the Company in making any such payment. The
Company at any time may require a Paying Agent (other than the Trustee) to pay
all money held by it to the Trustee and to account for any funds disbursed by
such Paying Agent. Upon complying with the previous sentence, the Paying Agent
(if other than the Company or a Subsidiary) shall have no further liability for
the money delivered to the Trustee. If the Company, or any of its Subsidiaries
or Affiliates, acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent.
Upon any bankruptcy, reorganization or similar proceeding with respect to the
Company, the Trustee shall serve as Paying Agent for the Debentures.


            In case Holders of any Debentures shall not, within two years after
such deposit, claim the cash so deposited, the Trustee or Paying Agent (as
applicable) shall, upon demand, pay over to the Company the balance so
deposited, or (if then held by the Company or any of its Subsidiaries or
Affiliates) such balance shall be discharged from such trust. Thereupon, the
Trustee or Paying Agent (as applicable) shall be relieved of all responsibility
to the Holders thereof, or if the Company or any of its Subsidiaries or
Affiliates acts as Paying Agent, such Paying Agent shall be relieved of all
responsibility as trustee of the cash so deposited; and the sole right of such
Holders shall be as a general creditor thereof. Any interest accrued on any
funds so deposited shall belong to the Company, and shall be paid to it from
time to time on demand.


            Section 2.6. Holder Lists. The Trustee shall preserve in as current
a form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders and shall otherwise comply with TIA Section
312(a). If the Trustee is not the Registrar, or to the extent otherwise required
under the TIA, the Company shall furnish or cause to be furnished to the
Trustee, in writing at least seven Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list, in
such form and as of such date as the Trustee may reasonably require, of the
names and addresses of Holders and the Company shall otherwise comply with TIA
Section 312(a).

            Section 2.7. Legends; Transfers and Exchanges; Etc.

            (a) Each Debenture shall bear a legend (the "Private Placement
Legend") substantially as set forth below:


                                       12
<PAGE>   19
            "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
            ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF
            THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
            AND WERE NOT REGISTERED UNDER ANY STATE SECURITIES LAW, AND MAY NOT
            BE OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT
            PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR PURSUANT TO AN
            EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
            REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE SECURITIES
            LAWS."

            (b) The Private Placement Legend shall be removed from a Debenture
if such Debenture is sold pursuant to an effective registration statement under
the Securities Act or there is delivered by the Company to the Trustee such
satisfactory evidence, which may include an opinion of independent counsel, as
reasonably may be requested by the Trustee, to confirm that neither such legend
nor the restrictions on transfer set forth therein are required to ensure that
transfer of such Debenture will not violate the registration and prospectus
delivery requirements of the Securities Act.

            (c) Restricted Debentures Legend. Upon the transfer, exchange or
replacement of Debentures not bearing a Private Placement Legend, the Registrar
shall deliver Debentures that do not bear a Private Placement Legend. Upon the
transfer, exchange or replacement of Debentures bearing a Private Placement
Legend, the Registrar shall deliver only Debentures that bear a Private
Placement Legend unless:

                  (i) such Debentures are transferred pursuant to an effective
            registration statement under the Securities Act, or

                  (ii) in connection with such transfer, the Registrar shall
            have received an Opinion of Counsel satisfactory to it to the effect
            that neither such legend nor the related restrictions on transfer
            are required in order to maintain compliance with the provisions of
            the Securities Act.

The Company shall deliver to the Trustee an Officer's Certificate promptly upon
effectiveness, withdrawal or suspension of any registration statement applicable
to any Debentures.

            (d) The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to this Article. The Company
shall have the right to inspect and make copies of all such letters, notices or
other written communications at any reasonable time upon the giving of
reasonable written notice to the Registrar.

            (e) Transfer and Exchange of Certificated Debentures. When
Certificated Debentures are presented by a Holder to the Registrar with a
request to register the transfer of the Certificated Debentures or to exchange
such Certificated Debentures for an equal principal amount of Certificated
Debentures of other authorized denominations, the Registrar shall register the
transfer or make the exchange as requested only if the Certificated Debentures
(i) are presented or surrendered for registration of transfer or exchange, (ii)
are endorsed and contain a


                                       13
<PAGE>   20

signature guarantee or are accompanied by a written instrument of transfer in
form satisfactory to the Registrar duly executed by such Holder or by his
attorney and (iii) contain a signature guarantee, duly authorized in writing.


            (f) Obligations with Respect to Transfers and Exchanges of
Debentures.

                  (i) To permit registrations of transfers and exchanges, the
      Company shall, subject to the other terms and conditions of this Article,
      execute and the Trustee shall authenticate Debentures at the Registrar's
      or co-registrar's request in accordance with the provisions of Section
      2.3.

                  (ii) No service charge shall be made to a Holder for any
      registration of transfer or exchange, but the Company may require payment
      of a sum sufficient to cover any stamp or transfer tax, assessments, or
      similar governmental charge payable in connection therewith (other than
      any such stamp or transfer taxes, assessments or similar governmental
      charges payable upon exchange pursuant to Section 5.1, Article VI or
      Section 10.5 not involving any transfer).

                  (iii) Prior to the due presentation for registration of
      transfer of any Debenture, the Company, the Trustee, the Paying Agent, the
      Registrar or any co-registrar may deem and treat the Person in whose name
      a Debenture is registered as the absolute owner of such Debenture for the
      purpose of receiving payment of principal of and interest on such
      Debenture and for all other purposes whatsoever, whether or not such
      Debenture is overdue, and none of the Company, the Trustee, the Paying
      Agent, the Registrar or any co-registrar shall be affected by notice to
      the contrary.

                  (iv) All Debentures issued upon any transfer or exchange
      pursuant to the terms of this Indenture shall be valid obligations of the
      Company; shall evidence the same debt; and shall be entitled to the same
      benefits under this Indenture as the Debentures surrendered upon such
      transfer or exchange.

                  (v) The Registrar shall not be required to register the
      transfer of or exchange any Debenture to be redeemed, in whole or in part,
      upon a change of control, except the unredeemed portion of any Debenture
      being redeemed in part.

            (g) No Obligation of the Trustee. The Trustee shall have no
obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Debenture other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

            Section 2.8. Mutilated, Destroyed, Lost or Stolen Debentures. If a
mutilated Debenture is surrendered to the Registrar, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Debenture of like tenor and principal amount and bearing a number not
outstanding. If the Holder of a Debenture claims that the Debenture has been
lost, destroyed or wrongfully taken, and if there shall be delivered to the
Company and


                                       14
<PAGE>   21
the Trustee (i) evidence to their reasonable satisfaction of the loss,
destruction or theft of such Debenture and (ii) an indemnity bond sufficient in
the reasonable judgment of the Company and the Trustee to protect the Company,
the Trustee, the Paying Agent and the Registrar and any co-registrar from any
loss any of them may suffer if such Debenture is replaced, then, the Company, in
the absence of notice to the Company or the Trustee that such Debenture has been
acquired by a bona fide purchaser, shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of like tenor and principal amount, bearing a number
not contemporaneously Outstanding if the requirements of Section 8-405 of the
Uniform Commercial Code as in effect in the State of New York are met.


            In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Debenture, pay such Debenture.

            Upon the issuance of any new Debenture under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

            Every new Debenture issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Debenture shall constitute an original
additional contractual obligation of the Company and any other obligor upon the
Debentures, whether or not the mutilated, destroyed, lost or stolen Debenture
shall be at any time enforceable by anyone, and shall be entitled to all
benefits of this Indenture equally and proportionately with any and all other
Debentures duly issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Debentures.

            Section 2.9. Temporary Debentures. Until definitive Debentures are
ready for delivery, the Company may execute and the Trustee shall authenticate
and deliver temporary Debentures. Temporary Debentures shall be substantially in
the form of definitive Debentures but may have variations that the Company
reasonably considers appropriate for temporary Debentures. Without unreasonable
delay, the Company shall prepare definitive Debentures. After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the temporary Debentures at any office
or agency maintained by the Company for that purpose and such exchange shall be
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Debentures, the Company shall execute, and the Trustee shall
authenticate and make available for delivery in exchange therefor, one or more
definitive Debentures representing an equal principal amount of Debentures.
Until so exchanged, the Holder of temporary Debentures shall in all respects be
entitled to the same benefits under this Indenture as a Holder of definitive
Debentures.

            Section 2.10. Cancellation. The Company at any time may deliver
Debentures to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee


                                       15
<PAGE>   22
any Debentures surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel and return to the Company all
Debentures surrendered for registration of transfer, exchange, payment,
redemption or cancellation. The Company may not issue new Debentures to replace
Debentures it has paid or delivered to the Trustee for cancellation except as
expressly permitted by this Indenture.

            Section 2.11. Payment of Interest; Defaulted Interest. (a) Interest
on any Debenture which is payable, and is punctually paid or duly provided for,
on any interest payment date shall be paid to the Person in whose name such
Debenture (or one or more predecessor Debentures) is registered at the close of
business on the regular record date for such interest as provided in the
Debenture at the office or agency of the Company maintained for such purpose
pursuant to Section 2.4.

            (b) Any interest on any Debenture which is payable, but is not paid
when the same becomes due and payable and such nonpayment continues for a period
of 30 days shall forthwith cease to be payable to the Holder on the regular
record date by virtue of having been such Holder, and such defaulted interest
and (to the extent lawful) interest on such defaulted interest at the rate borne
by the Debentures (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest") shall be paid by the Company, to the
Persons in whose names the Debentures (or their respective predecessor
Debentures) are registered at the close of business on a Special Record Date (as
hereinafter defined) for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Debenture and
the date (not less than 30 days after such notice) of the proposed payment (the
"Special Interest Payment Date"), and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as provided in this clause.
Thereupon the Trustee shall fix a record date (the "Special Record Date") for
the payment of such Defaulted Interest which shall be not more than 15 days and
not less than 10 days prior to the Special Interest Payment Date. The Trustee
shall promptly notify the Company of such Special Record Date, and in the name
and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date and Special Interest Payment
Date therefor to be given in the manner provided for in Section 12.2 not less
than 10 days prior to such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date and Special Interest
Payment Date therefor having been so given, such Defaulted Interest shall be
paid on the Special Interest Payment Date to the Persons in whose names the
Debentures (or their respective predecessor Debentures) are registered at the
close of business on such Special Record Date.

            (c) Subject to the foregoing provisions of this Section, each
Debenture delivered under this Indenture upon registration of, transfer of, or
in exchange for or in lieu of, any other Debenture shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Debenture.


                                       16
<PAGE>   23
            (d) All references in this Indenture and in the Debenture annexed
hereto as Exhibit A to "interest" payable in respect of the Debentures shall
include Defaulted Interest, where applicable.

            Section 2.12. Record Date. The record date for purposes of
determining the identity of Holders of the Debentures entitled to vote or
consent to any action by vote or consent authorized or permitted under this
Indenture shall be determined as provided for in TIA Section 316(c).

            Section 2.13. Computation of Interest. Interest on the Debentures
shall be computed on the basis of a 360-day year consisting of twelve 30-day
months (four 90-day quarters) and the actual number of days elapsed in the
period for which payable.


            Section 2.14. CUSIP Number. The Company in issuing the Debentures
may use a "CUSIP" number, and if it does so, the Trustee shall use the CUSIP
number in notices of redemption or exchange as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness or accuracy of the CUSIP number printed in the notice or on the
Debentures and that reliance may be placed only on the other identification
numbers printed on the Debentures. The Company shall promptly notify the Trustee
of any change in the CUSIP number.

maintain each office or agency required under Section 2.4. The Company will give

            (b) The Company may also from time to time designate one or more
other offices or agencies (in or outside of The City of New York) where the
Debentures may be presented or surrendered for any or all such purposes and may
from time to time rescind any such designation; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, City of
New York for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and any change in the location of
any such other office or agency.

Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the corporate rights (charter
and statutory), licenses and franchises of the Company; provided, however, that
the Company shall not be required to preserve any such right, license or
franchise if the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not, and will not be, disadvantageous
in any material respect to the Holders.

            Section 3.4. Compliance Certificate. (a) The Company shall file with
the Trustee and the SEC, and transmit to Holders, such information, documents

Company, the signers would normally have knowledge of any default or Event of
Default and whether or not, to the best of such signer's knowledge (after due
inquiry), any default or Event of Default has occurred during such period. If
such signers state that a default or Event of Default has occurred, the
certificate shall describe the default or Event of Default, its status and what
action the Company is taking or proposes to take with respect thereto. The
Company also shall comply with TIA Section 314(a).

            Section 3.5. Further Instruments and Acts. Upon request of the

covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other law that
would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Debentures as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent that it may
lawfully do so) the Company hereby expressly waives all benefit or advantage of
any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

            Section 3.7. Restrictions on Dividends. So long as any Debentures
are Outstanding, the Board of Directors shall not declare, and the Company shall
not pay or set apart for payment any dividend on any capital stock of the
Company or make any payment on account of, or set apart for payment money for a
sinking or other similar fund for, the repurchase, redemption or other
retirement of, any capital stock of the Company or any warrants, rights or
options exercisable for or convertible into any capital stock of the Company
(other than the repurchase, redemption or other retirement of debentures or
other debt securities that are convertible into or exchangeable for any capital
stock of the Company), or make any distribution in respect of capital stock of
the Company, either directly or indirectly, and whether in cash, obligations or
shares of the Company or other property (other than distributions or dividends
in capital stock to the holders of capital stock), and shall not permit any
corporation or other entity directly or indirectly controlled by the Company to
purchase or redeem any capital stock of the Company or any warrants, rights,
calls or options exercisable for or convertible into any capital stock of the
Company (other than the repurchase, redemption or other retirement of debentures
or other debt securities that are convertible into or exchangeable for any
capital stock of the Company) unless prior to or concurrently with such
declaration, payment, setting apart for payment, repurchase, redemption or other
retirement or distribution, as the case may be, all interest that has become due
and payable on the Debentures shall have been paid. Notwithstanding the
foregoing, this Section shall not prohibit the acquisition, repurchase,
exchange, conversion, redemption or other retirement for value by the Company of
Debentures in accordance with this Indenture or of any shares of Trust Preferred
Stock.

                                   ARTICLE IV

                                  VOTING RIGHTS


            Section 4.1. Voting Rights and Certain Restrictions. (a) The
Investor and its Affiliates, in their capacity as Holders of Debentures, shall
be entitled to vote on all matters voted on by holders of Common Stock, and
shall vote together with shares of Common Stock (and any shares of Series D
Cumulative Preferred Stock or Series D Debentures entitled to vote) as a single
class; provided, however, that (i) such voting rights shall apply to such
Debentures issued to the Investor or any Affiliate of the Investor in exchange
for shares of Series E Cumulative Preferred Stock that had similar voting rights
and (ii) upon transfer of a Debenture or any portion thereof to any Person other
than the Investor or an Affiliate of the Investor, such Person, and any
subsequent transferee, shall not be entitled to such voting rights with respect
to such Debenture or the transferred portion thereof, regardless of whether any
such Debentures are subsequently acquired by the Investor or its Affiliates.


            (b) With respect to any such vote provided for in subsection (a),
the Investor (together with its Affiliates) shall be entitled with respect to
its Debentures to an aggregate number of votes equal to the Investor Aggregate
Vote Number (as hereinafter defined).

            The "Investor Aggregate Vote Number" shall equal the number of
Warrant Shares that would be issuable upon the exercise of the Original Warrants
(as hereinafter defined) by the holders thereof (assuming all conditions
precedent to such exercise have been satisfied and that such exercise occurs as
of the record date for such vote), multiplied by the lesser of (x) the quotient
of the number of Original Warrants that are Beneficially Owned by members of the


                                       19
<PAGE>   26

Investor Group, in the aggregate, as of the record date for such vote (excluding
for purposes of this calculation, however, any Original Warrants that have been
transferred on the books of the Company by any member of the Investor Group to
any Person other than a member of the Investor Group, regardless of whether any
such Original Warrants are subsequently acquired by any member of the Investor
Group), divided by the number of Original Warrants, and (y) the quotient of the
aggregate principal amount of Original Debentures (as hereinafter defined) that
are Beneficially Owned by members of the Investor Group, in the aggregate, as of
the record date for such vote (excluding for purposes of this calculation,
however, any Original Debentures transferred by any member of the Investor Group
to any Person other than a member of the Investor Group, regardless of whether
any such Original Debentures are subsequently acquired by any member of the
Investor Group), divided by the aggregate principal amount of the Original
Debentures. The term "Original Warrants" means those Warrants Beneficially Owned
by members of the Investor Group, in the aggregate, as of May 13, 1998. The term
"Original Debentures" means those Debentures Beneficially Owned by members of
the Investor Group, in the aggregate, as of the Issue Date; provided, however,
that "Original Debentures" shall not include any Debentures issued in respect of
Series E Cumulative Preferred Stock previously issued as a dividend on Series E
Cumulative Preferred Stock.



            (c) If on any date (i) interest due and payable on either the
Debentures or the Series D Debentures shall not have been paid in full (or, if
the Series D Cumulative Preferred Stock has not been exchanged for Series D
Debentures, dividends payable on the Series D Cumulative Preferred Stock shall
have been in arrears and not paid in full) for four consecutive quarterly
periods or (ii) the Company shall have failed to satisfy its obligation to
redeem or repay the principal of either Debentures in accordance with this
Indenture or Series D Debentures in accordance with the Series D Indenture (or,
if the Series D Cumulative Preferred Stock has not been exchanged for Series D
Debentures, the Company shall have failed to satisfy its obligation to redeem
shares of Series D Cumulative Preferred Stock pursuant to the Certificate of
Designations thereof), then the number of directors constituting the Board of
Directors shall, without further action, be increased by two, and the holders of
Debentures and Series D Debentures representing at least a majority of the
aggregate principal amount of Outstanding Debentures and Series D Debentures
shall have, in addition to the other voting rights set forth herein, the
exclusive right, voting together as a single class without regard to series, to
elect the two directors (the "Additional Directors") of the Company to fill such
newly-created directorships (provided, that, if the shares of Series D
Cumulative Preferred Stock have not been exchanged for Series D Debentures, then
the holders of the shares of Series D Cumulative Preferred Stock shall vote
together with the holders of Debentures as a single class, and, for the purposes
of determining a majority of the aggregate principal amount of Debentures and
Series D Cumulative Preferred Stock, one share of Series D Cumulative Preferred
Stock shall be deemed to be equal to a principal amount of $1,000).
Notwithstanding the foregoing, the Investor and its Affiliates shall not be
permitted to elect, pursuant to the preceding sentence, more than the number of
directors that would result in four directors designated for nomination or
elected by the Investor and its Affiliates then being on the Board of Directors
(including directors that the Investor has a right to designate for nomination
to the Board of Directors pursuant to the Investment Agreement); provided, that,
if at the time Holders of Debentures and holders of Series D Debentures (or, if
applicable, holders of shares of Series D Cumulative Preferred Stock) have the
right to elect Additional Directors and (i) the Investor and its Affiliates
Beneficially Own, in the aggregate, Debentures and Series D Debentures
representing a majority



                                       20
<PAGE>   27

of the aggregate principal amount of Outstanding Debentures and Series D
Debentures (or, if the shares of Series D Cumulative Preferred Stock have not
been exchanged for Series D Debentures, a majority of the aggregate principal
amount of the Debentures and Series D Cumulative Preferred Stock), taken
together as a single class, and (ii) the Investor and its Affiliates are not
permitted to elect one or both of the Additional Directors as aforesaid, then
the Holders of Debentures and holders of Series D Debentures (or, if applicable,
holders of shares of Series D Cumulative Preferred Stock) (other than the
Investor and its Affiliates) shall have the right to elect, voting together as a
single class, one Additional Director pursuant to this subsection (c). For the
purposes of determining a majority of the aggregate principal amount of
Debentures and Series D Cumulative Preferred Stock if necessary pursuant to the
preceding sentence, one share of Series D Cumulative Preferred Stock shall be
deemed to be equal to a principal amount of $1,000. Additional Directors shall
continue as directors and such additional voting right shall continue until such
time as (a) all interest due and payable on the Debentures and Series D
Debentures and all dividends accumulated on the Series D Cumulative Preferred
Stock, as the case may be, shall have been paid in full and (b) any redemption
obligation with respect to, or any obligation to repay the principal of, the
Debentures, the Series D Debentures and the Series D Cumulative Preferred Stock,
as the case may be, that has become due shall have been satisfied or all
necessary funds shall have been set aside for payment, as the case may be, at
which time such Additional Directors shall cease to be directors and such
additional voting right of the Holders shall terminate subject to revesting in
the event of each and every subsequent event of the character indicated above
and subject to any rights as to the election of directors provided for the
holders of any series of preferred stock of the Company.


            (d) In the event that one or more of the Investor Nominees (as such
term is defined in the Investment Agreement) required to be designated for
election to the Board of Directors pursuant to the Investment Agreement are not
so designated or are not elected to the Board of Directors and the Investor or
any of its Affiliates Beneficially Owns Debentures, then the number of directors
constituting the Board of Directors shall, without further action, be increased
by the number of such Investor Nominees not elected to the Board of Directors
pursuant to the Investment Agreement, and such Holder or Holders shall have, in
addition to the other voting rights set forth herein, the exclusive right,
voting separately as a single class, to elect a number of directors to the Board
of Directors equal to the number of such Investor Nominees not elected to the
Board of Directors. Directors elected pursuant to this subsection shall continue
as directors and such additional voting right shall continue until such time as
the requisite number of Investor Nominees are elected to the Board of Directors
pursuant to the Investment Agreement, at which time the directors elected by the
Investor and its Affiliates pursuant to this subsection shall cease to be
directors (unless elected as Investor Nominees), and such additional voting
rights shall terminate subject to revesting in the event of each and every
subsequent event of the character indicated above.

            (e) (i) The foregoing rights of Holders to take any action as
provided in this Section may be exercised at any annual meeting of stockholders
or at a special meeting of Holders held for such purpose as hereinafter provided
or at any adjournment thereof, or by the written consent, delivered to the
Secretary of the Company, of the Holders of Debentures representing the minimum
principal amount of Outstanding Debentures required to take such action. So long
as such right to vote continues (and unless such right has been exercised by
written consent of the Holders of Debentures representing the minimum principal
amount of


                                       21
<PAGE>   28
Outstanding Debentures required to take such action), the Chairman of
the Board of Directors may call, and upon the written request of Holders of
Debentures representing 20% of the aggregate principal amount of the Outstanding
Debentures, addressed to the Secretary of the Company at the principal office of
the Company, shall call, a special meeting of the Holders entitled to vote as
provided herein. Such meeting shall be held within 60 days after delivery of
such request to the Secretary, at the place and upon the notice provided by law
and in the By-laws of the Company for the holding of meetings of stockholders.


            (ii) Each director elected pursuant to subsection (c) or (d) of this
Section shall serve until the next annual meeting or until his or her successor
shall be elected and shall qualify, unless the director's term of office shall
have terminated pursuant to the provisions of subsection (c) or (d) of this
Section, as the case may be. In case any vacancy shall occur among the directors
elected pursuant to subsection (c) or (d) of this Section, such vacancy may be
filled for the unexpired portion of the term by vote of the remaining director
or directors theretofore elected by such Holders (and, if applicable, holders of
the Series D Debentures or holders of shares of Series D Cumulative Preferred
Stock) (or such director's or directors' successor in office), if any. If any
such vacancy is not so filled within 20 days after the creation thereof or if
all of the directors so elected shall cease to serve as directors before their
term shall expire, the Holders (and, if applicable, holders of the Series D
Debentures or holders of shares of Series D Cumulative Preferred Stock) entitled
to vote for such director pursuant to the provisions of subsection (c) or (d) of
this Section, as the case may be, may elect successors to hold office for the
unexpired terms of any vacant directorships, by written consent as herein
provided, or at a special meeting of such Holders called as provided herein. The
Holders of Debentures (and, if applicable, holders of the Series D Debentures or
holders of shares of Series D Cumulative Preferred Stock) representing a
majority of the principal amount of Debentures entitled to vote for directors
pursuant to subsection (c) or (d) of this Section, as the case may be, shall
have the right to remove with or without cause at any time and replace any
directors such Holders (and, if applicable, holders of the Series D Debentures
or holders of shares of Series D Cumulative Preferred Stock) have elected
pursuant to such section, by written consent as herein provided, or at a special
meeting of such Holders (and, if applicable, holders of the Series D Debentures
or holders of shares of Series D Cumulative Preferred Stock) called as provided
herein.


            (f) Without the consent or affirmative vote of the Holders of
Debentures, voting separately as a class, representing at least a majority of
the aggregate principal amount of Outstanding Debentures, the Company shall not
authorize, create or issue, or increase the authorized amount of any class or
series of capital stock or any security convertible into or exercisable for any
class or series of capital stock, redeemable mandatorily or redeemable at the
option of the holder thereof at any time on or prior to May 13, 2008 (whether or
not only upon the occurrence of a specified event); provided, however, that no
consent or vote of the Holders shall be required for the creation or issuance by
a trust formed at the direction of the Company of any series of preferred
securities of such trust for financing purposes in an aggregate amount not to
exceed $250,000,000 ("Trust Preferred Stock").

            (g) Without the consent or affirmative vote of the Holders of
Debentures, voting separately as a class, representing at least a majority of
the aggregate principal amount of Outstanding Debentures, the Company shall not
(i) amend, alter or repeal any provision of the Certificate of Incorporation or
the By-laws of the Company, if the amendment, alteration or


                                       22
<PAGE>   29
repeal alters or changes the rights of the Holders of the Debentures so as to
affect them materially and adversely, or (ii) authorize or take any other action
if such action alters or changes any of the rights of Holders of the Debentures
in any respect or otherwise would be inconsistent with the provisions of this
Indenture and the holders of any class or series of the capital stock of the
Company are entitled to vote thereon.

            (h) The Company shall not enter into any agreement or issue any
security that prohibits, conflicts or is inconsistent with, or would be breached
by, the Company's performance of its obligations hereunder.

                                    ARTICLE V

                                SUCCESSOR COMPANY

            Section 5.1. Merger, Consolidation and Sale of Assets. The Company
shall not consolidate with or merge with or into, or convey, transfer or lease
all or substantially all its assets to, any Person, unless:

            (i) the resulting, surviving or transferee Person (the "Successor
      Company") shall be a corporation, partnership, trust, limited liability
      company or other similar entity organized and existing under the laws of
      the United States of America, any State thereof or the District of
      Columbia and the Successor Company (if not the Company) shall expressly
      assume, by supplemental indenture, executed and delivered to the Trustee,
      in form satisfactory to the Trustee, all the obligations of the Company
      under the Debentures and this Indenture;

            (ii) immediately after giving effect to such transaction, no default
      or Event of Default shall have occurred and be continuing;

            (iii) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that such
      consolidation, merger or transfer and such supplemental indenture, if any,
      comply with this Indenture.

            For purposes of this Section the sale, lease, conveyance,
assignment, transfer, or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Company, which
properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the transfer of all or
substantially all of the properties and assets of the Company.

            The Successor Company will succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture, but, in
the case of a lease of all or substantially all its assets, the Company will not
be released from the obligation to pay the principal of and interest on the
Debentures.

                            REDEMPTION OF DEBENTURES

            Section 6.1.  Redemption.  The Debentures may or shall (as
applicable) be redeemed, subject to the conditions and at the Redemption
Prices specified in the form of Debentures set forth in Exhibit A hereto.

            Section 6.2.  Applicability of Article.  Redemption of
Debentures, as permitted or required by any provision of this Indenture,
shall be made in accordance with this Article.

            Section 6.3.  Notice of Redemption.  (a)  Notwithstanding the
provisions of Section 12.2, notice of redemption shall be given in the manner
provided for in this Section.

            (b) Notice of the redemption of Debentures (a "Notice of
Redemption") shall be sent to each Holder to be redeemed by first class mail,
postage prepaid, at each such Holder's address as it is registered in the
Debenture Register, not more than 120 days nor fewer than 90 days prior to the
date fixed for redemption, which date shall be set forth in such notice (the
"Redemption Date"); provided, that failure to give such Notice of Redemption to
any Holder, or any defect in such Notice of Redemption to any Holder shall not
affect the validity of the proceedings for the redemption of Debentures held by
any other Holder. Notwithstanding the foregoing, in the event that
contemporaneously with or prior to the delivery of a Notice of Redemption, the
Company irrevocably deposits, in accordance with Section 6.5, funds sufficient
to pay the aggregate Redemption Price (as defined in Exhibit A hereto) for the
Debentures, such Notice of Redemption shall be delivered not more than 120 days
nor fewer than 30 days prior to the Redemption Date; provided, however, that, if
such Notice of Redemption is delivered fewer than 60 days prior to the
Redemption Date and the Investor or any of its Affiliates Beneficially Owns
Debentures as of the date of the Notice of Redemption and uses its reasonable
best efforts to consummate the sale of all or a portion of its Debentures prior
to the stated Redemption Date but has not completed such sale, the Company
shall, at the option of the Investor (or any such Affiliate), delay such
Redemption Date for a period not to exceed 30 days as requested by the Investor
(or any such Affiliate) in order to complete such sale or sales, and shall
notify the Holders of such delay within five days of receiving the request
therefor. Any delay of the Redemption Date pursuant to the proviso to the
preceding sentence shall be requested by the Investor (or any such Affiliate) in
writing no later than the tenth day preceding the then-scheduled Redemption Date
stated in the Notice of Redemption. The Redemption Date stated in a Notice of
Redemption shall not be delayed pursuant to this subsection more than once in
connection with the redemption of Debentures pursuant to such Notice of
Redemption.

            (c) All Notices of Redemption shall state:

                  (1)  the Redemption Date,

                  (2)  the Redemption Price,

                  (3) that on the Redemption Date the Redemption Price will
      become due and payable upon each such Debenture, or the portion thereof,
      to be redeemed, and, unless the Company defaults in making the redemption
      payment, that interest on


                                       24
<PAGE>   31
      Debentures called for redemption (or the portion thereof) will cease to
      accrue on and after said date,

                  (4) the place or places where such Debentures are to be
      surrendered for payment of the Redemption Price,

                  (5)  the name and address of the Paying Agent,

                  (6) that Debentures called for redemption must be surrendered
      to the Paying Agent to collect the Redemption Price, and

                  (7) the CUSIP number of the Debentures.

            (d) From and after the Redemption Date, all interest on Debentures
shall cease to accrue and all rights of the Holders thereof as Holders of
Debentures shall cease and terminate, except to the extent the Company shall
default in payment thereof on the Redemption Date.

            (e) Prior to any Redemption Date that has been fixed by the Company
in accordance with this Section, the Company shall take all measures reasonably
requested by the Investor to facilitate a sale or other disposition of
Debentures by the Investor or its Affiliates prior to such Redemption Date,
including, without limitation, participation in due diligence sessions and
provision of information about the management, business and financial condition
of the Company, preparation of offering memoranda, private placement memoranda
and other similar documents and preparation and delivery of such other
certificates or documents reasonably requested by the Investor.

            Section 6.4. Change of Control Notice and Redemption Procedures. (a)
In the event there occurs a Change of Control, any Holder, in accordance with
the procedures set forth below, may require the Company to redeem any or all of
the Debentures held by such Holder at the Redemption Price therefor. For all
purposes of this Indenture, unless the context otherwise requires, all
provisions relating to redemption in the event of a Change of Control pursuant
to this Section shall relate, in the case of any Debenture redeemed only in
part, to the portion of the principal amount of such Debenture which has been or
is to be redeemed.

            (b) Notice of any Change of Control shall be sent to the Holders not
more than five days following a Change of Control, which notice (a "Change of
Control Notice") shall describe the transaction or transactions constituting
such Change of Control and set forth each Holder's right to require the Company
to redeem any or all Debentures held by him or her or any portion thereof, the
Redemption Date (which date shall be not more than 30 days from the date of such
Change of Control Notice) and the procedures to be followed by such Holder in
exercising its right to cause such redemption; provided, however, that if
Debentures are owned by more than 50 Holders or groups of Affiliated Holders and
if the Debentures are listed on any national securities exchange or quoted on
any national quotation system, the Company shall give such Change of Control
Notice by publication in a newspaper of general circulation in the Borough of
Manhattan, The City of New York, within 30 days following such Change of Control
and, in any case, a similar notice shall be mailed concurrently to each Holder.
Failure by the Company to give the Change of Control Notice as prescribed by the
preceding sentence, or the

                                                            Exhibits 4.3 and 4.2

formal insufficiency of any such Change of Control Notice, shall not prejudice
the rights of any Holder to cause the Company to redeem any such Debentures held
by him or her.

            (c) In the event a Holder shall elect to require the Company to
redeem any or all such Debentures or any portion thereof pursuant to Section
6.4(a), such Holder shall deliver, prior to the Redemption Date as set forth in
the Change of Control Notice, or, if the Change of Control Notice is not given
as required by Section 6.4(b) at any time following the last day the Company was
required to give the Change of Control Notice in accordance with Section 6.4(b)
(in which case the Redemption Date shall be the date which is the later of (x)
30 days following the last day the Company was required to give the Change of
Control Notice in accordance with Section 6.4(b) and (y) 15 days following the
delivery of such election by such Holder), a written notice, in the form
specified by the Company (if the Company did in fact give the notice required by
Section 6.4(b)), to the Company so stating, and specifying the Debentures or
portions thereof to be redeemed pursuant to Section 6.4(a); provided, however,
that if all of the Debentures are owned by 50 or fewer Holders or groups of
Affiliated Holders, such Holders or groups may deliver a notice of an election
to redeem at any time within 90 days following the occurrence of a Change of
Control without awaiting receipt of a Change of Control Notice or the expiration
of the time allowed for the delivery of a Change of Control Notice hereunder.
The Company shall redeem the Debentures or portions thereof so specified on the
Redemption Date fixed by the Company or as provided in the preceding sentence.
The Company shall comply with the requirements of Rules 13e-4 and 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Debentures as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Section, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations hereunder by virtue thereof.


            Section 6.5. Deposit of Redemption Price. On or prior to the
relevant Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent, as a trust fund for the benefit of the Holders of Debentures to be
redeemed, an amount of cash sufficient to pay the Redemption Price of all the
Debentures which are to be redeemed in accordance with the Notice of Redemption
or Change of Control Notice, with irrevocable instructions and authority to the
Trustee or Paying Agent (as applicable) to pay to the respective Holders, as
evidenced by a list of such Holders certified by an officer of the Company, the
Redemption Price upon surrender of their respective Debentures. Such deposit
shall be deemed to constitute full payment of such Debentures, and from and
after the date of such deposit, all rights of the Holders of Debentures that are
to be redeemed, except the right to receive the Redemption Price upon the
surrender of their respective Debentures, shall cease and terminate. After the
Redemption Date, no interest shall accrue on any Debentures to be redeemed
(unless the Company shall fail to deposit cash sufficient to redeem all such
Debentures). In case Holders of any Debentures called for redemption shall not,
within two years after such deposit, claim the cash deposited for redemption
thereof, the Trustee or Paying Agent (as applicable) shall, upon demand, pay
over to the Company the balance so deposited, or (if then held by the Company
or any of its Subsidiaries or Affiliates) such balance shall be discharged from
such trust. Thereupon, the Trustee or Paying Agent (as applicable) shall be
relieved of all responsibility to the Holders thereof, or if the Company or any
of its Subsidiaries or Affiliates acts as Paying Agent, such Paying Agent shall
be relieved of all responsibility as trustee of the cash so deposited; and the
sole right of such Holders, with respect to Debentures to be redeemed, shall be
to receive the Redemption Price as general creditors of the Company. Any
interest accrued on any funds so deposited shall belong to the Company, and
shall be paid to it from time to time on demand.

            Section 6.6. Debentures Payable on Redemption Date. On or after the
Redemption Date, each Holder of Debentures called for redemption shall surrender
its Debenture to the Company at the place designated in the Notice of Redemption
or Change of Control Notice and shall thereupon be entitled to receive payment
of the Redemption Price.

            Section 6.7. Debentures Redeemed in Part. Upon surrender of a
Debenture which is to be redeemed in part in accordance with the provisions of
this Article, the Company shall execute, and the Trustee shall authenticate and
make available for delivery to the Holder of such Debenture (or to any other
Person as directed by the Holder of such Debenture) at the expense of the
Company, a new Debenture or Debentures, of any authorized denomination as
requested by such Holder, in an aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Debenture so
surrendered.

            Section 6.8. Rating Conditions. For so long as the Investor or an
Affiliate of the Investor holds any Debentures, no Notice of Redemption in
connection with a redemption pursuant to Section 6.1 shall be delivered unless
(i) the Company's unsecured debt is rated Baa or better by Moody's or BBB or
better by S&P or (ii) the Company has sufficient funds reasonably available
under committed lines of credit or other similar sources of financing
established with financially sound financing providers to pay, on the Redemption
Date, the aggregate Redemption Price in connection with such redemption (and
shall reserve such funds or availability for the payment of the aggregate
Redemption Price); provided, that the Company may deliver a Notice of Redemption
without complying with the foregoing conditions if prior to, or
contemporaneously with, the delivery of such notice the Company irrevocably
deposits in accordance with Section 6.5 funds sufficient to pay the aggregate
Redemption Price for the Debentures.

                                   ARTICLE VII

                              DEFAULTS AND REMEDIES

            Section 7.1.  Events of Default.  An "Event of Default" shall
occur if:

            (1) the Company defaults in the payment of the principal of any
      Debenture when the same becomes due and payable at its maturity, upon
      redemption, upon required repurchase, upon declaration or otherwise;

            (2) the Company defaults in the performance of or breaches any other
      covenant or agreement in this Indenture or under the Debentures (other
      than referred to in (1) above) and such default or breach continues for 60
      days after the notice specified below;

            (3) the Company, pursuant to or within the meaning of any Bankruptcy
      Law:

                  (A) commences a voluntary case;

                  (B) consents to the entry of an order for relief against it in
            an involuntary case;


                                       27
<PAGE>   34

                  (C) consents to the appointment of a Custodian of it or for
            any substantial part of its property; or

                  (D) makes a general assignment for the benefit of its
            creditors;

            or takes any comparable action under any foreign laws relating to
            insolvency;

            (4) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                  (A) is for relief against the Company in an involuntary
            case;

                  (B) appoints a Custodian of the Company or for any substantial
            part of its property; or

                  (C) orders the winding up or liquidation of the Company;

            and the order, decree or relief remains unstayed and in effect
            for 60 days.

            The foregoing will constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

            Notwithstanding the foregoing, a default under clause (2) of this
Section will not constitute an Event of Default until the Trustee or the Holders
of more than 25% in aggregate principal amount of the Outstanding Debentures
deliver to the Company written notice of the default and the Company does not
cure such default within the time specified in said clause (2) after receipt of
such notice. Such notice must specify the default, demand that it be remedied
and state that such notice is a "Notice of Default."

            The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any default or Event of Default under clauses (2), (3) and (4) of this Section,
their status and what action the Company is taking or proposes to take in
respect thereof.


           Section 7.2. Acceleration of Maturity; Rescission and Annulment. If
an Event of Default (other than an Event of Default specified in Section 7.1(3)
or Section 7.1(4)) occurs and is continuing, the Trustee by written notice to
the Company, or the Holders of at least 25% in aggregate principal amount of the
Outstanding Debentures by written notice to the Company and the Trustee, may,
and the Trustee at the request of such Holders shall, declare the principal of
and accrued but unpaid interest on all the Debentures to be due and payable.
Upon such a declaration, such principal and accrued and unpaid interest shall be
immediately due and payable. If an Event of Default specified in Section 7.1(3)
or Section 7.1(4) occurs, the principal of and accrued and unpaid interest on
all the Debentures will become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Holders of a
majority in aggregate principal amount of the then Outstanding Debentures by
written notice to the Trustee may rescind and annul an acceleration and its
consequences if the



                                       28
<PAGE>   35
rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal or interest that has become
due solely because of the acceleration) have been cured or waived.

            Section 7.3. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Debentures or to enforce the performance of
any provision of the Debentures or this Indenture.

            The Trustee may maintain a proceeding even if it does not possess
any of the Debentures or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.


            Section 7.4. Waiver. The Investor and its Affiliates, so long as
such Persons own at least 20% of the aggregate principal amount of Outstanding
Debentures and subject to the TIA, or the Holders of not less than a majority of
the aggregate principal amount of Outstanding Debentures, by their consent
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for Debentures), may waive by written
notice to the Trustee an existing default or Event of Default and its
consequences except (i) a default or Event of Default under Section 7.1(1) or an
Event of Default under Section 7.1(2) in respect of a default in the payment of
interest on the Debentures or (ii) a default or Event of Default in respect of a
provision that under Section 10.2 cannot be amended without the consent of each
Holder. Notwithstanding the preceding sentence, a waiver by the Investor and its
Affiliates of an existing default or Event of Default shall not be effective if
Holders of a majority of the aggregate principal amount of Outstanding
Debentures (i) have delivered to the Company pursuant to Section 7.1 written
notice of a default under Section 7.1(2) in respect of such default, (ii)
pursuant to Section 7.2, have declared the principal of and accrued but unpaid
interest on all Debentures to be due and payable by virtue of such Event of
Default, or (iii) give written notice to the Trustee that such Holders do not
consent to the waiver of such default or Event of Default and its consequences.
When a default or Event of Default is waived, it is deemed cured, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any consequent right.


            Section 7.5. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such
suit, and may assess costs against any such party litigant, in the manner and to
the extent provided in the TIA; provided, that neither this Section nor the TIA
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company, to any suit instituted
by the Trustee, to any suit instituted by any Holder, or group of Holders,
holding in the aggregate more than 10% in principal amount of the Debentures, or
to any suit by a Holder for the enforcement of the payment of the principal of
or interest on any Debenture, on or after the respective due dates expressed in
such Debenture.


                                       29
<PAGE>   36
            Section 7.6. Control. The Holders of a majority of the aggregate
principal amount of the Outstanding Debentures may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. Subject to Section 8.1
and Section 8.2, however, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or that the Trustee determines is unduly
prejudicial to the rights of other Holders; provided, however, that the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent
with such direction.

            Section 7.7.  Limitation on Suits.  Subject to Section 7.8, a
Holder may not pursue any remedy with respect to this Indenture or the
Debentures unless:

            (1) the Holder gives to the Trustee written notice stating that an
      Event of Default is continuing;

            (2) the Investor and its Affiliates, so long as such Persons own at
      least 20% of the aggregate principal amount of Outstanding Debentures and
      subject to the TIA, or the Holders of at least 25% of the aggregate
      principal amount of Outstanding Debentures make a written request to the
      Trustee to pursue the remedy;

            (3) such Holder or Holders offer to the Trustee reasonable security
      or indemnity against any loss, liability or expense;

            (4) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer of security or indemnity; and

            (5) the Investor and its Affiliates, so long as such Persons own at
      least 20% of the aggregate principal amount of Outstanding Debentures and
      subject to the TIA, or the Holders of a majority of the aggregate
      principal amount of Outstanding Debentures do not give the Trustee a
      direction that, in the opinion of the Trustee, is inconsistent with such
      request during such 60-day period, provided, however, that any such
      direction given by the Investor and its Affiliates shall be disregarded
      for all purposes of this clause (5) if (i) such request was made by
      Holders of a majority of the aggregate principal amount of Outstanding
      Debentures or (ii) such Holders give the Trustee a direction that, in the
      opinion of the Trustee, is inconsistent with such direction given by the
      Investor and its Affiliates;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

            Section 7.8. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture (including, without limitation, Sections
7.6 and 7.7) or the Debentures, the right of any Holder to receive payment of
principal of or interest on the Debentures held by such Holder, on or after the
respective due dates expressed in the Debentures (or, in the case of redemption,
on the Redemption Date), or to bring suit for the enforcement of


                                       30
<PAGE>   37
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

            Section 7.9. Collection Suit by Trustee. If an Event of Default
specified in Section 7.1(1) or an Event of Default specified in Section 7.1(2)
in respect of a default in the payment of interest on the Debentures occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee
of an express trust against the Company for the whole amount then due and owing
(together with applicable interest, to the extent lawful) and the amounts
provided for in Section 8.7.

            Section 7.10. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders allowed in
any judicial proceedings relative to the Company, its Subsidiaries or its or
their respective creditors or properties and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
Custodian and shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the TIA in
order to have claims of the Holders and the Trustee allowed in any such
proceeding. Without limiting the generality of the foregoing, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same, and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.7.

            No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Debentures or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

            Section 7.11.  Priorities.  If the Trustee collects any money or
property pursuant to this Article, it shall pay out the money or property in
the following order:

            FIRST:  to the Trustee for amounts due under Section 8.7;

            SECOND:  if the Holders proceed against the Company directly
      without the Trustee in accordance with this Indenture, to Holders for
      their collection costs;

            THIRD:  to Holders for amounts due and unpaid on the Debentures
      for principal and interest, ratably, without preference or priority of
      any kind, according to the amounts due and payable on the Debentures
      for principal and interest, respectively; and

            FOURTH:  to the Company.


                                       31
<PAGE>   38
The Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section. At least 15 days before such record date, the Company
shall mail to each Holder and the Trustee a notice that states the record date,
the payment date and amount to be paid.

                                  ARTICLE VIII

                                     TRUSTEE

            Section 8.1. Duties of Trustee. (a) If a default or an Event of
Default has occurred and is continuing, the Trustee shall exercise the rights
and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs; provided, that if an
Event of Default occurs and is continuing, the Trustee will be under no
obligation to exercise any of the rights or powers under this Indenture at the
request or direction of any of the Holders unless such Holders have offered to
the Trustee reasonable indemnity or security against loss, liability or expense.

            (b) Except during the continuance of a default or an Event of
Default:

            (1) the Trustee undertakes to perform such duties and
      responsibilities and only such duties and responsibilities as are provided
      by the TIA or specifically set forth in this Indenture and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, in the case of any such certificates or opinions which by any
      provisions hereof are specifically required to be furnished to the
      Trustee, the Trustee shall examine such certificates and opinions to
      determine whether or not such certificates or opinions conform to the
      requirements of this Indenture (but need not confirm or investigate the
      accuracy of mathematical calculations or other facts stated therein).

            (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

            (1) this paragraph does not limit the effect of paragraph (b) of
      this Section;

            (2) the Trustee shall not be liable for any error of judgment made
      in good faith by a Trust Officer unless it is proved that the Trustee was
      negligent in ascertaining the pertinent facts; and

            (3) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 7.2, Section 7.4 or Section 7.5.

            (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.


                                       32
<PAGE>   39
            (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

            (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

            (g) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

            (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

            (i) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

            (j) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

            Section 8.2.  Rights of Trustee.  (a) Subject to Section 8.1, the
Trustee may rely on any document reasonably believed by it to be genuine and
to have been signed or presented by the proper Person.  The Trustee need not
investigate any fact or matter stated in the document.

            (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on an
Officers' Certificate or Opinion of Counsel.

            (c) The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute
willful misconduct or negligence.

            (e) The Trustee may consult with counsel of its selection, and the
advice or Opinion of Counsel with respect to legal matters relating to this
Indenture and the Debentures shall be full and complete authorization and
protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

            Section 8.3. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Debentures
and may otherwise deal with the


                                       33
<PAGE>   40
Company or its Affiliates with the same rights it would have if it were not
Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the
same with like rights. However, the Trustee must comply with Section 8.10 and
Section 8.11.

            Section 8.4. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Debentures, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Debentures or in the Debentures other than the
Trustee's certificate of authentication.

            Section 8.5. Notice of Defaults. If a default or Event of Default
occurs and is continuing and if a Trust Officer has knowledge thereof, the
Trustee shall mail to each Holder notice of the default or Event of Default as
and to the extent provided by the TIA within 30 days after it is known to a
Trust Officer or written notice of it is received by the Trustee. Except in the
case of a default or Event of Default in payment of principal of or interest on
any Debenture (including payments pursuant to the optional redemption or
required repurchase provisions of such Debenture, if any), the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is not opposed to the interests of
the Holders.

            Section 8.6. Reports by Trustee to Holders. The Trustee shall comply
with TIA Section 313. The Company agrees to notify promptly the Trustee whenever
the Debentures become listed on any stock exchange and of any delisting thereof.

            Section 8.7. Compensation and Indemnity. (a) The Company shall pay
to the Trustee from time to time reasonable compensation for its acceptance of
this Indenture and services hereunder as the Company and the Trustee shall from
time to time agree in writing. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, costs of preparing and reviewing reports,
certificates and other documents, costs of preparation and mailing of notices to
Holders and reasonable costs of counsel retained by the Trustee in connection
with the delivery of an Opinion of Counsel or otherwise, in addition to the
compensation for its services, except any such expense as may be attributable to
its negligence or bad faith. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts.

            (b) The Company shall jointly and severally indemnify the Trustee
against any and all losses, liabilities or expenses (including reasonable
attorneys' fees and expenses) incurred by it, without negligence or bad faith on
its part, in connection with the administration of this trust and the
performance of its duties hereunder, including the costs and expenses of
enforcing this Indenture (including this Section) and of defending itself
against any claims (whether asserted by any Holder, the Company or otherwise).
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable fees and expenses of such counsel
provided that the Company shall not be required to pay such fees and expenses if
it assumes the Trustee's defense,


                                       34
<PAGE>   41
and, in the reasonable judgment of outside counsel to the Trustee, there is no
conflict of interest between the Company and the Trustee in connection with such
defense. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee's own
willful misconduct, negligence or bad faith. The Company need not pay for any
settlement made without its consent.

            (c) To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Debentures on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Debentures. The Trustee's right to
receive payment of any amounts due under this Section shall not be subordinate
to any other liability or Indebtedness of the Company.

            (d) The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a default specified in Section 7.1(3) or Section 7.1(4) with
respect to the Company, the expenses are intended to constitute expenses of
administration under any Bankruptcy Law; provided, however, that this shall not
affect the Trustee's rights as set forth in this Section or Section 7.10.

            Section 8.8.  Replacement of Trustee.  (a)  A resignation or
removal of  the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee's acceptance of appointment as
provided in this Section.

            (b) The Trustee may resign at any time by giving written notice
thereof to the Company. The Investor and its Affiliates, so long as such Persons
own at least 20% of the aggregate principal amount of the Outstanding
Debentures, or the Holders of a majority of the aggregate principal amount of
the Outstanding Debentures may remove the Trustee by giving written notice
thereof to the Trustee and may appoint a successor Trustee. The Company shall
remove the Trustee if:

            (1) the Trustee fails to comply with Section 8.10;

            (2) the Trustee is adjudged bankrupt or insolvent or an order for
            relief is entered with respect to the Trustee under any Bankruptcy
            law;

            (3) a receiver or other public officer takes charge of the Trustee
            or its property; or

            (4) the Trustee otherwise becomes incapable of acting.

            (c) If the Trustee resigns or is removed by the Company, by the
Investor and its Affiliates or by Holders of Debentures in accordance with this
Indenture, and the Investor and its Affiliates or such Holders do not reasonably
promptly appoint a successor Trustee, or if a vacancy exists in the office of
the Trustee for any reason (the Trustee in such event being referred to herein
as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

            (d) A successor Trustee shall execute, acknowledge and deliver a
written acceptance of its appointment to the retiring Trustee and to the
Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee


                                       35
<PAGE>   42
shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section
8.7.

            (e) If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Investor
and its Affiliates, so long as such Persons own at least 20% of the aggregate
principal amount of the Outstanding Debentures, or the Holders of 10% of the
aggregate principal amount of the Outstanding Debentures may petition, at the
Company's expense, any court of competent jurisdiction for the appointment of a
successor Trustee.

            (f) If the Trustee fails to comply with Section 8.10, any Holder who
has been a Holder of a Debenture for at least six months may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

            (g) Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 8.7 shall continue for the
benefit of the retiring Trustee.

            Section 8.9. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

            In case at the time such successor or successors shall succeed to
the trusts created by this Indenture, any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such
Debentures so authenticated; and in case at that time any of the Debentures
shall not have been authenticated, any successor to the Trustee may authenticate
such Debentures either in the name of any predecessor hereunder or in the name
of the successor to the Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Debentures or in this Indenture
provided that the certificate of the Trustee shall have.

            Section 8.10. Eligibility; Disqualification. There shall at all
times be a Trustee hereunder that is a corporation organized and doing business
under the laws of the United States of America or of any state thereof that is
authorized under such laws to exercise corporate trust powers, and that is
subject to supervision or examination by federal or state authorities. The
Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Trustee shall have a combined capital and surplus of at least $500 million as
set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures
under which other securities or certificates of interest or participation in
other securities of the Company are Outstanding if the requirements for such
exclusion set forth in TIA Section 310(b)(1) are met.

            Section 8.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A


                                       36

Trustee who has resigned or been removed shall be subject to TIA Section 311(a)
to the extent indicated.

                                   ARTICLE IX

                   SATISFACTION AND DISCHARGE OF INDENTURE

            Section 9.1.  Termination of the Company's Obligations.

            This Indenture will be satisfied and discharged and will cease to be
of further effect (except as to surviving rights of registration of transfer or
exchange of the Debentures and except as to compensation and indemnity to the
Trustee, as expressly provided for below) as to all Outstanding Debentures when:

            (a) either (i) all the Debentures theretofore authenticated and
      delivered (except lost, stolen or destroyed Debentures which have been
      replaced or paid as provided in Section 2.8 and Debentures for whose
      payment money has theretofore been deposited in trust or segregated and
      held in trust by the Company and thereafter repaid to the Company or
      discharged from such trust as provided in Section 2.5) have been delivered
      to the Trustee for cancellation or (ii) all Debentures not theretofore
      delivered to the Trustee for cancellation have become due and payable and
      the Company thereafter has irrevocably deposited or caused to be deposited
      with the Trustee funds in an amount sufficient to pay and discharge the
      entire Indebtedness on the Debentures not theretofore delivered to the
      Trustee for cancellation, for principal of and interest on the Debentures
      to the date of deposit together with irrevocable instructions from the
      Company directing the Trustee to apply such funds to the payment thereof;

            (b) no default or Event of Default with respect to this Indenture or
      the Debentures shall have occurred and be continuing on the date of such
      deposit or shall occur as a result of such deposit and such deposit will
      not result in a breach or violation of, or constitute a default under, any
      other instrument to which the Company is a party or by which it is bound;

            (c) the Company shall have paid all other sums payable by it
      hereunder or under the Debentures; and

            (d) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent providing for the termination of the Company's obligations under
      the Debentures and this Indenture have been complied with. Such Opinion of
      Counsel shall also state that such satisfaction and discharge does not
      result in a default under any instrument evidencing debt senior to the
      Debentures or any other agreement or instrument then known to such counsel
      that binds or affects the Company.

            Notwithstanding the foregoing paragraph, the Company's obligations
in Sections 2.6, 2.7, 2.9, 2.10 and 8.7 shall survive until the Debentures are
no longer Outstanding. After the Debentures are no longer Outstanding, the
Company's obligations in Section 8.7 shall survive.


                                       37
<PAGE>   44
            After such delivery or irrevocable deposit, the Trustee upon request
shall acknowledge in writing the satisfaction and discharge of the Company's
obligations under the Debentures and this Indenture except for those surviving
obligations specified above.

                                    ARTICLE X

                           AMENDMENTS AND SUPPLEMENTS

            Section 10.1.  Without Consent of Holders.  (a)  Notwithstanding
Section 10.2, the Company and the Trustee, in accordance with this Article,
may amend or supplement this Indenture or the Debentures without notice to or
consent of any Holder:

            (1)  to cure any ambiguity or inconsistency;

            (2) to comply with Article V in respect of the assumption by a
      Successor Company of an obligation of the Company under this Indenture;

            (3) to provide for uncertificated Debentures in addition to or in
      place of certificated Debentures; provided, however, that the
      uncertificated Debentures are issued in registered form for purposes of
      Section 163(f) of the Code or in a manner such that the uncertificated
      Debentures are described in Section 163(f)(2)(B) of the Code;

            (4) to add guarantees with respect to the Debentures or to secure
      the Debentures;

            (5) to add to the covenants of the Company for the benefit of the
      Holders or to surrender any right or power herein conferred upon the
      Company; or

            (6) to comply with any requirements of the SEC in connection with
      qualifying this Indenture under the TIA or to provide for the succession
      of a successor Trustee in accordance with the terms hereof prior to such
      amendment or supplement;

provided, that any such change does not adversely affect the rights of any
Holder in any material respect.

            Section 10.2. With Consent of Holders. The Company, and the Trustee
may amend or supplement this Indenture or the Debentures without notice to any
Holder but with the written consent of the Holders of at least a majority of the
aggregate principal amount of the Outstanding Debentures (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Debentures). However, without the consent of each Holder
affected, an amendment or supplemental Indenture may not:

            (1) reduce the percentage in principal amount of the Outstanding
      Debentures whose Holders must consent to an amendment, supplement or
      waiver;

            (2) reduce the rate of or change or have the effect of changing the
      time for payment of interest on any Debentures;


                                       38
<PAGE>   45
            (3) reduce the principal of or change or have the effect of changing
      the fixed maturity of any Debentures, or change the date on which any
      Debentures may be subject to redemption, or reduce the Redemption Price
      therefor;

            (4) make any Debentures payable in money other than that stated in
      the Debentures;

            (5) make any change in the provisions of this Indenture entitling
      each Holder to receive payment of principal of and interest on such
      Debentures on or after the due date thereof or to bring suit to enforce
      such payment, or permitting Holders of a majority of the aggregate
      principal amount of Outstanding Debentures as set forth herein on the
      Issue Date to waive defaults or Events of Default; or

            (6) amend, change or modify in a manner that would adversely affect
      the interests of the Holders in any respect, the obligation of the Company
      to redeem Debentures if a Change of Control occurs.

            It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

            Section 10.3.  Compliance with Trust Indenture Act.  Every
amendment or supplement to this Indenture or the Debentures shall comply with
the TIA as then in effect.

            Section 10.4. Amended or Supplemental Indenture. (a) Upon the
request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental Indenture pursuant
to Section 10.1 or Section 10.2, upon receipt by the Trustee of an Officer's
Certificate or an Opinion of Counsel, which it reasonably believes to be genuine
and to have been signed or presented by the proper Person, and, in the case of
an amendment of supplement pursuant to Section 10.2, upon the filing with the
Trustee of the consent of Holders of Debentures as described in Section 10.2,
the Trustee shall join with the Company in the execution of such amended or
supplemental Indenture, unless such amended or supplemental Indenture affects
the Trustee's own rights, duties or immunities under this Indenture or otherwise
in a manner adverse to it, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture. In
signing such amended or supplemental Indenture the Trustee shall be entitled to
receive indemnity reasonably satisfactory to it and to receive, and (subject to
Section 8.1 and Section 8.2) shall be fully protected in relying upon, such
evidence as it deems appropriate, including, without limitation, solely on an
Opinion of Counsel stating that such amendment or supplemental Indenture is
authorized or permitted by this Indenture.

            (b) After an amended or supplemental Indenture under this Section
becomes effective, the Company shall mail to Holders a notice briefly describing
such amended or supplemental Indenture. The failure to give such notice to all
Holders, or any defect therein, shall not impair or affect the validity of an
amended or supplemental Indenture under this Section.


                                       39
<PAGE>   46
            Section 10.5. Revocation and Effect of Consents and Waivers. A
consent to an amendment, supplement or a waiver by a Holder of a Debenture shall
bind the Holder and every subsequent Holder of that Debenture or portion of the
Debenture that evidences the same debt as the consenting Holder's Debenture,
even if notation of the consent or waiver is not made on the Debenture. However,
any such Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Debenture or portion of the Debenture if the Trustee receives the
written notice of revocation before the date the amendment, supplement or waiver
becomes effective. After an amendment, supplement or waiver becomes effective,
it shall bind every Holder. An amendment, supplement or waiver shall become
effective upon receipt by the Trustee of the requisite number of written
consents under Section 10.2.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 90
days after such record date.

            Section 10.6. Notation on or Exchange of Debentures. If an amendment
or supplement changes the terms of a Debenture, the Trustee may require the
Holder of the Debenture to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Debenture regarding the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Debenture shall issue and the Trustee shall
authenticate a new Debenture that reflects the changed terms. Failure to make
the appropriate notation or to issue a new Debenture shall not affect the
validity of such amendment or supplement.

                                   ARTICLE XI

                         SUBORDINATION OF THE DEBENTURES


            Section 11.1. Agreement to Subordinate. The Company agrees, and each
Holder by accepting a Debenture agrees, that the Indebtedness evidenced by the
Debentures is subordinated in right of payment, to the extent and in the manner
provided in this Article, to the prior payment in full of all Senior
Indebtedness of the Company and that the subordination is for the benefit of and
enforceable by the holders of such Senior Indebtedness. Only Senior Indebtedness
of the Company shall rank senior to the Debentures in accordance with the
provisions set forth herein, and the Debentures shall in all respects rank pari
passu with, or be senior to, all other Indebtedness of the Company. The
Debentures shall in all respects rank pari passu with, and not senior to, any
Series D Debentures. All provisions of this Article shall be subject to Section
11.12.


            Section 11.2. Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total


                                       40
<PAGE>   47
or partial dissolution of the Company or in a winding up or bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property:

            (1) holders of Senior Indebtedness of the Company shall be entitled
to receive payment in full of such Senior Indebtedness before Holders of the
Debentures shall be entitled to receive any payment of principal of or interest
on the Debentures; and

            (2) until such Senior Indebtedness is paid in full, any distribution
to which Holders would be entitled but for this Article shall be made to holders
of such Senior Indebtedness as their interests may appear, except that Holders
may receive (a) securities of a Person that are subordinated ("Subordinated
Reorganization Securities") to such Senior Indebtedness to at least the same
extent as the Debentures are subordinated to (A) Senior Indebtedness of the
Company and (B) any Indebtedness or securities issued in exchange for Senior
Indebtedness, and (b) payments and other distributions made from any funds
deposited by the Company pursuant to Section 9.1.

            Section 11.3. Default on Senior Indebtedness of the Company. The
Company may not pay the principal of or interest on the Debentures or make any
deposit pursuant to Section 9.1 and may not repurchase, redeem or otherwise
retire any Debentures (collectively, "pay the Debentures") (other than in the
form of Subordinated Reorganization Securities and payments and other
distributions made from any funds deposited by the Company pursuant to Section
9.1) if (i) any Senior Indebtedness of the Company is not paid when due or (ii)
any other default on such Senior Indebtedness occurs and the maturity of such
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, (x) the default has been cured or waived and any such acceleration
has been rescinded or (y) such Senior Indebtedness has been paid in full;
provided, however, that the Company may pay the Debentures without regard to the
foregoing if the Company and the Trustee receive written notice approving such
payment from the representative of such Senior Indebtedness with respect to
which either of the events set forth in clause (i) or (ii) of this sentence has
occurred and is continuing. During the continuance of any default (other than a
default described in clause (i) or (ii) of the preceding sentence) with respect
to any Senior Indebtedness of the Company pursuant to which the maturity thereof
may be accelerated immediately without further notice (except such notice as may
be required to effect such acceleration) or the expiration of any applicable
grace periods, the Company may not pay the Debentures for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
representative of the holders of such Senior Indebtedness specifying an election
to effect a Payment Blockage Period and ending 179 days thereafter (or earlier
if such Payment Blockage Period is terminated (i) by written notice to the
Trustee and the Company from the Person or Persons who gave such Blockage
Notice, (ii) because the default giving rise to such Blockage Notice is no
longer continuing or (iii) because such Senior Indebtedness has been repaid in
full). Notwithstanding the provisions of the immediately preceding sentence (but
subject to the provisions of the first sentence of this Section), unless the
holders of such Senior Indebtedness or the representative of such holders have
accelerated the maturity of such Senior Indebtedness, the Company may resume
payments on the Debentures after such Payment Blockage Period. The Debentures
shall not be subject to more than one Payment Blockage Period in any consecutive
360-day period, irrespective of the number of defaults with respect to Senior
Indebtedness during such period. For purposes of this Section, no default or
event of


                                       41
<PAGE>   48
default with respect to the Senior Indebtedness and which existed or was
continuing on the date of the commencement of any Payment Blockage Period and
which initiated such Payment Blockage Period shall be, or be made, the basis of
the commencement of a subsequent Payment Blockage Period by the representative
of such Senior Indebtedness, whether or not within a period of 360 consecutive
days, unless such default or event of default shall have been cured or waived
for a period of not less than 90 consecutive days.

            Section 11.4. Acceleration of Payment of Debentures. If payment of
the Debentures is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Senior Indebtedness of the
Company (or their representative) of the acceleration.

            Section 11.5. When Distribution Must Be Paid Over. If a distribution
is made to Holders that because of this Article should not have been made to
them, the Holders who receive the distribution shall hold it in trust for
holders of Senior Indebtedness of the Company and pay it over to them as their
interests may appear.

            Section 11.6. Subrogation. After all Senior Indebtedness of the
Company is paid in full and until the Debentures are paid in full, Holders shall
be subrogated to the rights of holders of such Senior Indebtedness to receive
distributions applicable to such Senior Indebtedness. A distribution made under
this Article to holders of such Senior Indebtedness which otherwise would have
been made to Holders is not, as between the Company and Holders, a payment by
the Company on such Senior Indebtedness.

            Section 11.7.  Relative Rights.  This Article defines the
relative rights of Holders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall:

            (1) impair, as between the Company and Holders, the obligation of
the Company, which is absolute and unconditional, to pay principal of and
interest on the Debentures in accordance with their terms; or


            (2) prevent the Trustee or any Holder from exercising its available
remedies upon a default in respect of the Debentures (including, without
limitation, the remedies set forth in Article IV), subject to the rights, if
any, of holders of Senior Indebtedness of the Company to receive distributions
otherwise payable to Holders.


            Section 11.8. Subordination May Not Be Impaired by Company. No right
of any holder of Senior Indebtedness of the Company to enforce the subordination
of the Indebtedness evidenced by the Debentures shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

            Section 11.9. Rights of Trustee and Paying Agent. Notwithstanding
Section 11.3, the Trustee or Paying Agent may continue to make payments on the
Debentures and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives written notice satisfactory to it that payments may not be made under
this Article. The Company, the Registrar or co-registrar, the Paying Agent, a
representative or a holder of Senior Indebtedness may give such notice;
provided, however, that,


                                       42
<PAGE>   49
if the holders of an issue of Senior Indebtedness of the Company have a
representative, only the representative may give such notice.

            The Trustee in its individual or any other capacity may hold Senior
Indebtedness of the Company with the same rights it would have if it were not
Trustee. The Registrar and co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article with respect to any Senior Indebtedness of the Company which may at
any time be held by it, to the same extent as any other holder of such Senior
Indebtedness, and nothing in Article VII shall deprive the Trustee of any of its
rights as such holder. Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 8.7.

            Section 11.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of the Company, the distribution may be made and the notice given to their
representative (if any).

            Section 11.11. Article XI Not to Prevent Events of Default or Limit
Right to Accelerate. The failure to make a payment pursuant to the Debentures by
reason of any provision in this Article shall not be construed as preventing the
occurrence of a default in respect of the Debentures. Nothing in this Article
shall have any effect on the right of the Holders or the Trustee to accelerate
the maturity of the Debentures.

            Section 11.12. Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money held in trust
under Article IX by the Trustee for the payment of principal of and interest on
the Debentures shall not be subordinated to the prior payment of any Senior
Indebtedness or subject to the restrictions set forth in this Article, and none
of the Holders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness of the Company or any other creditor of the
Company.

            Section 11.13. Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article, the Trustee and the Holders shall be
entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 11.2
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Holders or (iii) upon the representative for the holders of Senior Indebtedness
of the Company for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of such Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of the Company to participate
in any payment or distribution pursuant to this Article, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of such Senior Indebtedness held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
other facts pertinent to the rights of such Person under this Article, and, if
such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such



                                       43

payment. The provisions of Section 8.1 and Section 8.2 shall be applicable to
all actions or omissions of actions by the Trustee pursuant to this Article.

            Section 11.14. Trustee to Effectuate Subordination. Each Holder by
accepting a Debenture authorizes and directs the Trustee on such Holder's behalf
to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Holders and the holders of Senior
Indebtedness of the Company as provided in this Article and appoints the Trustee
as attorney-in-fact for any and all such purposes.

            Section 11.15. Trustee Not Fiduciary for Holders of Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Holders or the Company or any other
Person, money or assets to which any holders of Senior Indebtedness of the
Company shall be entitled by virtue of this Article or otherwise.

            Section 11.16. Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Holder by accepting a Debenture acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration to each holder of any Senior Indebtedness of
the Company, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Debentures, to acquire and continue to hold such
Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed
conclusively to have relied on such subordination provisions in acquiring and
continuing to hold such Senior Indebtedness.

            Series D Junior Subordinated Debentures Due May 13, 2008

1.    Interest


            Oxford Health Plans, Inc. a Delaware corporation (such corporation,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called the "Company"), for value received promises to pay interest
on the principal amount of this Debenture quarterly on the last day of March,
June, September and December (and, if such date is a Legal Holiday, the Business
Day next succeeding such day) at a rate of 14.0% per annum. Interest on the
Debentures will accrue from the most recent date to which interest has been paid
on the Debentures or, if no interest has been paid, from the Issue Date. The
Company shall pay interest on overdue principal (plus interest on such interest
to the extent lawful), at the rate borne by the Debentures to the extent lawful.


2.    Method of Payment

            By at latest 10:00 a.m. (New York City time) on the date on which
any principal of or interest on any Debenture is due and payable, the Company
shall irrevocably deposit with the Trustee or the Paying Agent money sufficient
to pay such principal and/or interest. The Company will pay interest (except
Defaulted Interest) to the Persons who are registered Holders of Debentures at
the close of business on the fifteenth day preceding the relevant interest
payment date (the "Record Date") even if Debentures are canceled, repurchased or
redeemed after the Record Date and on or before the interest payment date.
Holders must surrender Debentures to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. The Company will make all payments in respect of a Debenture
(including principal and interest) by mailing a check to the registered address
of each Holder thereof; provided, however, that payments on the Debentures may
also be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Debentures, by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 2 Business Days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

3.    Paying Agent and Registrar

            Initially, [___] (the "Trustee," which term includes any successor
trustee under the Indenture), will act as Trustee, Paying Agent and Registrar.
The Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice to any Holder. The Company may act as Registrar or co-registrar
or Paying Agent.

4.    Indenture

            The Company issued the Debentures under an Indenture, dated as of
[____] (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the "Indenture"), among the Company and the Trustee. The
terms of the Debentures include those


                                      A-3
<PAGE>   58

stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect
on the date of the Indenture (the "Act"). Capitalized terms used herein and not
defined herein have the meanings ascribed thereto in the Indenture. The
Debentures are subject to all such terms, and Holders are referred to the
Indenture and the Act for a statement of those terms. Each Holder by accepting a
Debenture agrees to be bound by all of the terms and provisions of the
Indenture, as amended or supplemented from time to time.


            The Debentures are general unsecured senior obligations of the
Company limited to $[__________] in aggregate principal amount (subject to
Section 2.7, Section 2.8, Section 2.9, Section 6.7 and Section 10.6 of the
Indenture).

5.    Change of Control and Optional Redemption

            In the event of a Change of Control, any Holder may require the
Company to redeem any or all of the Debentures held by such Holder, in
accordance with the redemption procedures set forth in Article VI of the
Indenture, at 100% of principal amount, plus accrued and unpaid interest
(including Defaulted Interest) to the redemption date (the "Redemption Price")
(subject to the right of Holders of record on the relevant Record Date to
receive interest due on the relevant interest payment date). In the event of any
redemption of Debentures in part, a new Debenture or Debentures for the
unredeemed portion of the principal of the Debenture redeemed in part will be
issued upon cancellation of the Debenture surrendered.

            On and after May 13, 2003, the Debentures are redeemable by the
Company, in accordance with the redemption procedures set forth in Article VI of
the Indenture, in whole but not in part, at the Redemption Price.

6.    Denominations; Transfer; Exchange

            The Debentures are in registered form without coupons in
denominations of principal amount of $1,000 and integral multiples of $1,000. A
Holder may transfer or exchange Debentures in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar shall not be required to register
the transfer of or exchange any Debenture to be redeemed, in whole or in part,
upon a change of control, except the unredeemed portion of any Debenture being
redeemed in part.

7.    Subordination

            The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate in right of payment to the prior payment
in full of all Senior Indebtedness of the Company, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of

8.    Persons Deemed Owners

            The registered holder of this Debenture may be treated as the owner
of it for all purposes.

9.    Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

10.   Discharge Prior to Redemption

            Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the
Debentures and the Indenture if the Company deposits with the Trustee money for
the payment of principal and interest on the Debentures to redemption or
maturity, as the case may be.

11.   Amendment, Supplement or Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Debentures may be amended or supplemented with the written
consent of the Holders of at least a majority of the aggregate principal amount
of the Outstanding Debentures and (ii) any existing default or Event of Default
and its consequence (other than with respect to nonpayment or in respect of a
provision that cannot be amended without the written consent of each Holder
affected) may be waived with the written consent of the Investor and its
Affiliates (so long as such Persons own at least 20% of the aggregate principal
amount of Outstanding Debentures and subject to the TIA) or Holders of a
majority of the aggregate principal amount of the Outstanding Debentures.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Holder, the Company and the Trustee may amend or supplement the Indenture or
the Debentures to, among other things, cure any ambiguity or inconsistency, or
to comply with Article V of the Indenture, or to provide for uncertificated
Debentures in addition to or in place of certificated Debentures, or to add
guarantees with respect to the Debentures or to secure the Debentures, or to add
additional covenants of, or surrender rights and powers conferred on, the
Company, or to comply with any request of the SEC in connection with qualifying
the Indenture under the Act, or to provide for the succession of a successor
trustee in accordance with the terms of the Indenture prior to such amendment or
supplements, provided that any such change that does not adversely affect the
rights of any Holder in any material respect.

12    Defaults and Remedies

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Debentures may declare all
the Debentures to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Debentures being
due and payable immediately upon the occurrence of such Events of Default.


                                      A-5
<PAGE>   60
            Holders may not enforce the Indenture or the Debentures except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Debentures unless it receives reasonable indemnity or security. The Trustee
may withhold from Holders notice of any continuing default or Event of Default
(except a default or Event of Default in payment of principal or interest) if it
determines that withholding notice is in their interest.

13.   Trustee Dealings with the Company

            Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Debentures and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

14.   No Recourse Against Others

            An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Debentures, the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By
accepting a Debenture, each Holder waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the
Debentures.

15.   Authentication

            This Debenture shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Debenture.

entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants

Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Debentures and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders. No representation is made as
to the accuracy of such numbers either as printed on the Debentures or as
contained in any notice of redemption and reliance may be placed only on the

respect to Existing Holders, the Investment Agreement) or as may be required to
comply with any law or with any rule or regulation made pursuant thereto, or
with any regulation of any stock exchange on which the Warrants or the Warrant
Shares may be listed, or to conform to usage. Each Warrant Certificate shall be
signed on behalf of the Company by its chairman or vice-chairman of the board of
directors, or its president or vice-president, and by its treasurer or an
assistant treasurer, or its secretary or an assistant secretary. The signature
of any such officer on any Warrant Certificate may be manual or by facsimile.
Each Warrant Certificate, when so signed on behalf of the Company, shall be
delivered to the Warrant Agent together with an order for the countersignature
and delivery of such Warrants by the Warrant Agent.

         (c) The Warrant Agent shall, upon receipt of any Warrant Certificate
duly executed on behalf of the Company, countersign such Warrant Certificate and
deliver such Warrant Certificate to or upon the order of the Company. Each
Warrant Certificate shall be dated the date of its countersignature.

         (d) No Warrant Certificate shall be entitled to any benefit under this
Agreement or be valid or obligatory for any purpose, and no Warrant evidenced
thereby may be exercised, unless such Warrant Certificate has been countersigned
by the manual signature of the Warrant Agent. Such signature by the Warrant
Agent upon any Warrant Certificate executed by the Company shall be conclusive
evidence that such Warrant Certificate has been duly issued under the terms of
this Agreement.

         (e) If any officer of the Company who has signed any Warrant
Certificate either manually or by facsimile signature shall cease to be such
officer before such Warrant


                                        4
<PAGE>   8
Certificate shall have been countersigned and delivered by the Warrant Agent,
such Warrant Certificate nevertheless may be countersigned and delivered as
though the person who signed such Warrant Certificate had not ceased to be such
officer of the Company; and any Warrant Certificate may be signed on behalf of
the Company by such persons as, at the actual date of the execution of such
Warrant Certificate, shall be the proper officers of the Company as specified in
this Section 2.2, regardless of whether at the date of the execution of this
Agreement any such person was such officer.

         (f) The Warrantholders shall be entitled to receive Warrants in
physical, certificated registered form.

         SECTION 2.3. Transfer. A Warrant Certificate may be sold or otherwise
transferred at any time (except as such sale or transfer may be restricted
pursuant to the Securities Act or any applicable state securities laws) and any
such sale or transfer shall be effected on the Warrant Register upon surrender
of such Warrant Certificate at the corporate trust office of the Warrant Agent,
duly endorsed by the Warrantholder or by its duly authorized attorney or
representative, or accompanied by proper evidence of succession, assignment or
authority to transfer. Upon any registration of transfer, the Company shall
execute, and the Warrant Agent shall countersign and deliver, as provided in
Section 2.2, a new Warrant Certificate or Warrant Certificates of like tenor in
appropriate denomination to the Person or Persons entitled thereto.

         SECTION 2.4. Legend on Warrant Certificates and Warrant Shares. (a) By
acceptance of a Warrant Certificate, each Warrantholder is deemed to agree to
(i) the placement on such Warrant Certificate of a legend substantially as set
forth in Exhibit A hereto, in the case of Series A Warrants, or Exhibit B
hereto, in the case of Series B Warrants, and (ii) the placement on certificates
representing the Warrant Shares issuable upon exercise of Warrants held by such
Warrantholder of a legend substantially as set forth below:

            "THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,
            SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
            EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT OF
            1933, AS AMENDED (THE "SECURITIES ACT"), OR PURSUANT TO AN EXEMPTION
            FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
            REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE SECURITIES
            LAWS."

         (b) The legend shall be removed from a Warrant Certificate, or from a
certificate representing Warrant Shares, if the Warrants evidenced by such
Warrant Certificate, or such Warrant Shares, as the case may be, are sold
pursuant to an effective registration statement under the Securities Act (other
than to a person directly or indirectly controlling or controlled by the Company
or a person under direct or indirect common control with the Company) or there
is delivered to the Company such satisfactory evidence, which may include an
opinion of independent counsel, as reasonably requested by the Company, to
confirm that neither such legend nor the restrictions on transfer set forth
therein are required to ensure that transfers of such Warrants or Warrant
Shares, as the case may be, will not violate the registration and prospectus
delivery requirements of the Securities Act. Any such legend on a Warrant
Certificate may be changed or removed only upon notice by the Company to the
Warrant Agent.

         SECTION 2.5. Exchange of Warrant Certificate. Any Warrant Certificate
may be exchanged for another certificate or certificates of like tenor entitling
the Warrantholder to purchase a like aggregate number of Warrant Shares as the
certificate or certificates surrendered then entitles such Warrantholder to
purchase. Any Warrantholder desiring to exchange a Warrant Certificate shall
make such request in writing delivered to the Warrant Agent, and shall
surrender, properly endorsed, the certificate evidencing the Warrant to be so
exchanged. Thereupon, the Company shall execute, and the Warrant Agent shall
countersign and deliver, as provided in Section 2.2. hereof, to the Person
entitled thereto a new Warrant Certificate or Certificates as so requested.

         SECTION 2.6. Cancellation of Warrant Certificates. Any Warrant
Certificate surrendered to the Warrant Agent for transfer, exchange or exercise
of the Warrants evidenced thereby shall be promptly canceled by the Warrant
Agent and shall not be reissued and, except as expressly permitted by this
Agreement, no Warrant Certificate shall be issued hereunder in lieu thereof. The
Warrant Agent shall deliver to the


                                       5
<PAGE>   9
Company from time to time or otherwise dispose of canceled Warrant Certificates
in a manner satisfactory to the Company. Any Warrant Certificate surrendered to
the Company for transfer, exchange or exercise of the Warrants evidenced thereby
shall be promptly delivered to the Warrant Agent and such transfer, exchange or
exercise shall not be effective until such Warrant Certificate has been received
by the Warrant Agent.

         SECTION 2.7. Treatment of Holders of Warrant Certificates. Every
Warrantholder consents and agrees with the Company, the Warrant Agent and with
every subsequent Warrantholder that until the Warrant Certificate is transferred
on the books of the Warrant Agent, the Company and the Warrant Agent may treat
the registered Warrantholder of such Warrant Certificate as the absolute owner
of the Warrants evidenced thereby for any purpose and as the person entitled to
exercise the rights attaching to the Warrants evidenced thereby, any notice to
the contrary notwithstanding.


                                   ARTICLE III

                              EXERCISE OF WARRANTS

         SECTION 3.1. (a) A Warrantholder may exercise the Warrants, in whole or
in part, by presentation and surrender to the Warrant Agent of the Warrant
Certificate together with the attached Election to Exercise, in accordance with
Section 4.2 of the Warrant Certificate. If the date specified as the exercise
date is not a Business Day, the Warrants will be deemed to be received and
exercised on the next succeeding day which is a Business Day. If the Warrants
are received or deemed to be received after the Expiration Date, the exercise
thereof will be null and void and any funds delivered to the Warrant Agent will
be returned to the Warrantholder as soon as practicable. In no event will
interest accrue on funds deposited with the Warrant Agent in respect of an
exercise or attempted exercise of Warrants. The validity of any exercise of
Warrants will be determined by the Warrant Agent in its sole discretion and such
determination will be final and binding upon the Warrantholder and the Company.
Neither the Company nor the Warrant Agent shall have any obligation to inform a
Warrantholder of the invalidity of any exercise of Warrants. The Warrant Agent
shall deposit all funds received by it in payment of the Exercise Price in the
account of the Company maintained with the Warrant Agent for such purpose and
shall advise the Company upon its request by telephone at the end of each day on
which funds for the exercise of the Warrants are received of the amount so
deposited to its account. The Warrant Agent shall promptly confirm such
telephonic advice to the Company in writing.

         (b) The Warrant Agent shall, by 11:00 A.M. on the second Business Day
following the exercise date of any Warrant, advise the Company and the transfer
agent and registrar in respect of the Warrant Shares issuable upon such exercise
as to the number of Warrants exercised in accordance with the terms and
conditions of this


                                       6
<PAGE>   10
Agreement, the instructions of each Warrantholder with respect to delivery of
the Warrant Shares issuable upon such exercise, and the delivery of definitive
Warrant Certificates evidencing the balance, if any, of the Warrants remaining
after such exercise, and such other information as the Company or such transfer
agent and registrar shall reasonably require.

         (c) On the terms and subject to the conditions set forth in this
Agreement and in the Warrant Certificate, upon presentation and surrender of the
Warrant Certificate and payment of the aggregate Exercise Price as set forth in
Section 4.2 of the Warrant Certificate, the Company shall promptly issue and
cause to be delivered to the Warrant Agent a certificate or certificates (in
such name or names as the Warrantholder may designate in writing) for the
specified number of duly authorized, fully paid and non-assessable Warrant
Shares issuable upon exercise, and shall deliver to the Warrantholder cash, as
provided in Section 11 of the Warrant Certificate, with respect to any
Fractional Warrant Shares otherwise issuable upon such surrender. Upon receipt
of such Warrant Shares, the Warrant Agent shall transmit such Warrant Shares to
the Warrantholder, or to such Persons as the Warrantholder may designate in
writing together with, or preceded by, the prospectus in accordance with Section
7.5 hereof. The Company agrees that it will provide such information and
documents to the Warrant Agent as may be necessary for the Warrant Agent to
fulfill its obligations under this Agreement. In the event that the Warrants are
exercised in part prior to the Expiration Time, the Company shall issue and
cause to be delivered to the Warrant Agent a certificate or certificates (in
such name or names as the Warrantholder may designate in writing) evidencing any
remaining unexercised Warrants. Upon receipt of such Warrant Certificate, the
Warrant Agent shall countersign and deliver such Warrant Certificate to the
Warrantholder, or to such persons as the Warrantholder may designate in writing.

                                   ARTICLE IV

                                PAYMENT OF TAXES

         SECTION 4.1. Payment of Taxes. The Company shall pay any and all
documentary stamp or similar issue or transfer taxes and other governmental
charges that may be imposed under the laws of the United States of America or
any political subdivision or taxing authority thereof or therein in respect of
any issue or delivery of Warrant Shares or of other securities or property
deliverable upon exercise of the Warrants evidenced by a Warrant Certificate
or certificates representing such shares or securities (other than income taxes
imposed on the Warrantholder); provided that the Company shall not be required
to pay any such tax or other charge that may be imposed in connection with any
transfer involved in the issue of any certificate for Warrant Shares or other
securities or property, or payment of cash, to any Person other than the holder
of the Warrant Certificate surrendered upon exercise, and in case of any such
tax or charge, the Warrant Agent and the Company shall not be required to issue
any security or


                                       7
<PAGE>   11
property or pay any cash until such tax or charge has been paid or it has been
established to the Warrant Agent's and the Company's satisfaction that no such
tax or charge is payable.


                                    ARTICLE V

                          MUTILATED OR MISSING WARRANT

         SECTION 5.1. Mutilated or Missing Warrant. If any Warrant Certificate
is lost, stolen, mutilated or destroyed, the Company shall issue and the Warrant
Agent shall countersign, in exchange and substitution for and upon cancellation
of the mutilated Warrant Certificate, or in lieu of and substitution for the
Warrant Certificate lost, stolen or destroyed, upon receipt of a proper
affidavit or other evidence reasonably satisfactory to the Company and the
Warrant Agent (and surrender of any mutilated Warrant Certificate) and bond of
indemnity in form and amount and with corporate surety reasonably satisfactory
to the Company and the Warrant Agent in each instance protecting the Company and
the Warrant Agent, a new Warrant Certificate of like tenor and representing an
equivalent number of Warrants as the Warrant Certificate so lost, stolen,
mutilated or destroyed. Any such new Warrant Certificate shall constitute an
original contractual obligation of the Company, whether or not the allegedly
lost, stolen, mutilated or destroyed Warrant Certificate shall be at any time
enforceable by anyone. An applicant for such substitute Warrant Certificate
shall also comply with such other reasonable regulations and pay such other
reasonable charges as the Company or the Warrant Agent may prescribe. All
Warrant Certificates shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement of lost,
stolen, mutilated or destroyed Warrant Certificates, and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement of negotiable
instruments or other securities without their surrender.


                                   ARTICLE VI

                          CONCERNING THE WARRANT AGENT

         SECTION 6.1. Warrant Agent. The Company hereby appoints ChaseMellon

Warrants upon the terms and subject to the conditions herein set forth, and
ChaseMellon Shareholder Services, L.L.C. hereby accepts such appointment. The
Warrant Agent shall have the powers and authority granted to and conferred upon
it hereby and such further powers and authority to act on behalf of the Company
as the Company may hereafter grant to or confer upon it.


                                        8
<PAGE>   12
         SECTION 6.2. Limitations on Warrant Agent's Obligations. The Warrant
Agent accepts its obligations herein set forth upon the terms and conditions
hereof, including the following, to all of which the Company agrees:

                  (a) Compensation and Indemnification. The Company agrees to
         pay the Warrant Agent compensation to be agreed upon with the Company
         for all services rendered by the Warrant Agent and to reimburse the
         Warrant Agent for all reasonable out-of-pocket expenses (including
         reasonable counsel fees) incurred by the Warrant Agent in connection
         with the services rendered by it hereunder. The Company also agrees to
         indemnify the Warrant Agent for, and to hold it harmless against, any
         loss, liability or expense incurred without gross negligence, bad faith
         or willful misconduct on the part of the Warrant Agent, arising out of
         or in connection with its acting as Warrant Agent hereunder. Anything
         to the contrary notwithstanding, in no event shall the Warrant Agent be
         liable for special, punitive, indirect, consequential or incidental
         loss or damage of any kind whatsoever (including but not limited to
         lost profits), even if the Warrant Agent has been advised of the
         likelihood of such loss or damage.

                  (b) Agent for the Company. In acting in the capacity of
         Warrant Agent under this Agreement, the Warrant Agent is acting solely
         as agent of the Company and does not assume any obligation or
         relationship of agency or trust with any of the owners or holders of
         the Warrants.

                  (c) Counsel. The Warrant Agent may consult with counsel
         satisfactory to it (which may be counsel to the Company), and the
         written advice or opinion of such counsel shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in accordance with the
         written advice or opinion of such counsel.

                  (d) Documents. The Warrant Agent shall be authorized and
         protected and shall incur no liability for or in respect of any action
         taken, suffered or omitted by it in reliance upon any notice,
         direction, consent, certificate, affidavit, statement or other paper or
         document reasonably believed by it to be genuine and to have been
         presented or signed by the proper parties.

                  (e) Certain Transactions. The Warrant Agent, and its officers,
         directors and employees, may become the owner of, or acquire any
         interest in, any Warrant, with the same rights that it or they would
         have were it not the Warrant Agent hereunder, and, to the extent
         permitted by applicable law, it or they may engage or be interested in
         any financial or other transaction with the Company and may act on, or
         as a depositary, trustee or agent for, any committee or body of holders
         of Warrants or Warrant Shares, or other securities or obligations of
         the Company as freely as if it were not the Warrant Agent hereunder.
         Nothing in this Agreement


                                        9
<PAGE>   13
         shall be deemed to prevent the Warrant Agent from acting as trustee
         under the Series A Indenture or the Series E Indenture.

                  (f) No Liability for Interest. The Warrant Agent shall not be
         under any liability for interest on any monies at any time received by
         it pursuant to any of the provisions of this Agreement.

                  (g) No Liability for Invalidity. The Warrant Agent shall not
         be under any responsibility with respect to the validity or sufficiency
         of this Agreement or the execution and delivery hereof (except the due
         execution and delivery hereof by the Warrant Agent) or with respect to
         the validity or execution of the Warrant Certificates (except its
         countersignature thereon).

                  (h) No Responsibility for Recitals. The recitals contained in
         this Agreement and in the Warrant Certificates (except as to the
         Warrant Agent's countersignature thereon) shall be taken as the
         statements of the Company and the Warrant Agent assumes no
         responsibility hereby for the correctness of the same.

                  (i) No Implied Obligations. The Warrant Agent shall be
         obligated to perform such duties as are specifically set forth herein
         and no implied duties or obligations shall be read into this Agreement
         against the Warrant Agent. The Warrant Agent shall not be under any
         obligation to take any action hereunder which may tend to involve it in
         any expense or liability, the payment of which within a reasonable time
         is not, in its opinion, assured to it. The Warrant Agent shall not be
         accountable or under any duty or responsibility for the use by the
         Company of any Warrant Certificate authenticated by the Warrant Agent
         and delivered by it to the Company pursuant to this Agreement or for
         the application by the Company of the proceeds of the issue and sale,
         or exercise, of the Warrants. The Warrant Agent shall have no duty or
         responsibility in case of any default by the Company in the performance
         of its covenants or agreements contained in this Agreement or in any
         Warrant Certificate or in the case of the receipt of any written demand
         from a Warrantholder with respect to such default, including, without
         limiting the generality of the foregoing, any duty or responsibility to
         initiate or attempt to initiate any proceedings at law or otherwise or,
         except as provided in Section 7.2 hereof, to make any demand upon the
         Company.

                  (j) Instructions from Company. The Warrant Agent is hereby
         authorized and directed to accept instructions with respect to the
         performance of its duties hereunder from the Chairman of the Board, the
         President, any Vice President, the Chief Financial Officer or the
         Secretary of the Company, and to apply to such officers for advice or
         instructions in connection with its duties, and shall not be liable for
         any action taken, suffered or omitted to be taken by it in good faith
         in accordance with instructions of any such officers.


                                       10
<PAGE>   14
                  (k) Delegation. The Warrant Agent may execute and exercise any
of the rights or powers hereby vested in it to perform any duty hereunder either
itself or by or through its attorneys or agents.

         SECTION 6.3. Compliance with Applicable Laws. The Warrant Agent agrees
to comply with all applicable federal and state laws imposing obligations on it
in respect of the services rendered by it under this Agreement and in connection
with the Warrants, including (but not limited to) the provisions of United
States federal income tax laws regarding information reporting and backup
withholding. The Warrant Agent shall be responsible for its failure to comply
with any such laws imposing obligations on it, including (but not limited to)
any liability for its failure to comply with any applicable provisions of United
States federal income tax laws regarding information reporting and backup
withholding.

         SECTION 6.4. Appointment, Resignation and Appointment of Successor. (a)
The Company agrees, for the benefit of the Warrantholders from time to time,
that there shall at all times be a Warrant Agent hereunder until all the
Warrants issued hereunder have been exercised or have expired in accordance with
their terms, which Warrant Agent shall be appointed in the Borough of Manhattan,
The City of New York, and shall have a capital and surplus of at least
$50,000,000.

         (b) The Warrant Agent may at any time resign as such agent by giving
written notice to the Company of such intention on its part, specifying the date
on which it desires such resignation to become effective; provided that such
date shall not be less than three months after the date on which such notice is
given, unless the Company agrees to accept such notice less than three months
prior to such date of effectiveness. The Company may remove the Warrant Agent at
any time by giving written notice to the Warrant Agent of such removal,
specifying the date on which it desires such removal to become effective. Such
resignation or removal shall take effect upon the appointment by the Company, as
hereinafter provided, of a successor Warrant Agent (qualified as set forth in
subsection (a)) and the acceptance of such appointment by such successor Warrant
Agent. The obligation of the Company under Section 6.2(a) hereof shall continue
to the extent set forth therein notwithstanding the resignation or removal of
the Warrant Agent.

         (c) If at any time the Warrant Agent shall resign, or shall cease to be
qualified as set forth in subsection (a), or shall be removed, or shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or shall file
a petition seeking relief under any applicable Federal or State bankruptcy or
insolvency law or similar law, or make an assignment for the benefit of its
creditors or consent to the appointment of a receiver, conservator or custodian
of all or any substantial part of its property, or shall admit in writing its
inability to pay or to meet its debts as they mature, or if a receiver or
custodian of it or of all or any substantial part of its property shall be
appointed, or if an order of any court shall be entered for relief against it
under the provisions of any applicable Federal


                                       11
<PAGE>   15
or State bankruptcy or similar law, or if any public officer shall have taken
charge or control of the Warrant Agent or of its property or affairs, for the
purpose of rehabilitation, conservation or liquidation, a successor Warrant
Agent, qualified as set forth in subsection (a), shall be appointed by the
Company by an instrument in writing, filed with the successor Warrant Agent.
Upon the appointment as herein provided of a successor Warrant Agent and
acceptance by the latter of such appointment, the Warrant Agent so superseded
shall cease to be Warrant Agent under this Agreement.

         (d) Any successor Warrant Agent appointed under this Agreement shall
execute, acknowledge and deliver to its predecessor and to the Company an
instrument accepting such appointment, and thereupon such successor Warrant
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, trusts, immunities, duties and obligations of
such predecessor with like effect as if originally named as Warrant Agent under
this Agreement, and such predecessor, upon payment of its charges and
disbursements then unpaid, shall thereupon become obligated to transfer, deliver
and pay over, and such successor Warrant Agent shall be entitled to receive, all
monies, securities and other property on deposit with or held by such
predecessor, as Warrant Agent under this Agreement.

         (e) Any Person into which the Warrant Agent may be merged or converted
or any Person with which the Warrant Agent may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which the Warrant
Agent shall be a party, or any Person to which the Warrant Agent shall sell or
otherwise transfer all or substantially all the assets and business of the
Warrant Agent, in each case provided that it shall be qualified as set forth in
subsection (a), shall be the successor Warrant Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties to this Agreement, including, without limitation, any
successor to the Warrant Agent first named above.

                                  MISCELLANEOUS

         SECTION 7.1. Amendments. (a) This Agreement and any Warrant Certificate
may be amended by the parties hereto by executing a supplemental warrant

to increase the exercise price, (ii) shortens the period of time during which
the Warrants may be exercised, (iii) otherwise adversely affects the exercise
rights of the Warrantholders in any material respect, or (iv) reduces the number
of unexercised Warrants the consent of the Warrantholders of which is required
for amendment of this Agreement or the Warrants.

Warrant Agent may, but shall not be required to, enter any supplement or
amendment that affects the Warrant Agent's own rights, duties, obligations or
immunities under this Agreement.

of Series D Preferred Stock pursuant to clause (iii) or (v) in connection with
any exercise prior to May 13, 2000.


                  (b) On the terms and subject to the conditions set forth in
this Warrant Certificate, upon such presentation and surrender of this Warrant
Certificate and payment of such aggregate Exercise Price as set forth in
subsection (a) above, the Company shall promptly issue and cause to be delivered
to the Warrant Agent a certificate or certificates (in such name or names as the
Warrantholder may designate in writing) for the specified number of duly
authorized, fully paid and non-assessable Warrant Shares issuable upon exercise,
and shall deliver to the Warrantholder cash, as provided in Section 11 hereof,
with respect to any Fractional Warrant Shares otherwise issuable upon such
surrender. Upon receipt of such Warrant Shares, the Warrant Agent shall transmit
such Warrant Shares to the Warrantholder, or to such Persons as the
Warrantholder may designate in writing. In the event that the Warrants evidenced
by this Warrant Certificate are exercised in part prior to the Expiration Time,
the Company shall issue and cause to be delivered to the Warrant Agent a
certificate or certificates (in such name or names as the Warrantholder may
designate in writing) evidencing any remaining unexercised Warrants. Upon
receipt of such Warrant Certificate, the Warrant Agent shall countersign and
deliver such Warrant Certificate to the Warrantholder, or to such persons as the
Warrantholder may designate in writing.

                  (c) Each Person in whose name any certificate for Warrant
Shares is issued shall for all purposes be deemed to have become the holder of
record of the Warrant Shares represented thereby on the first date on which both
the Warrant Certificate evidencing the respective Warrants was surrendered and
payment of the Exercise Price and any applicable taxes was made, irrespective of
date of issue or delivery of such certificate.

                  Section 5. Payment of Taxes. The Company shall pay any and all
documentary, stamp or similar issue or transfer taxes and other governmental
charges that may be imposed under the laws of the United States of America or
any political subdivision or taxing authority thereof or therein in respect of
any issue or delivery of Warrant Shares or of other securities or property
deliverable upon exercise of the


                                       A-7
<PAGE>   28
Warrants evidenced by this Warrant Certificate or certificates representing such
shares or securities (other than income taxes imposed on the Warrantholder);
provided that the Company shall not be required to pay any such tax or other
charge that may be imposed in connection with any transfer involved in the issue
of any certificate for Warrant Shares or other securities or property, or
payment of cash, to any Person other than the holder of the Warrant Certificate
surrendered upon exercise, and in case of any such tax or charge, the Warrant
Agent and the Company shall not be required to issue any security or property or
pay any cash until such tax or charge has been paid or it has been established
to the Warrant Agent's and the Company's satisfaction that no such tax or charge
is payable.

                  Section 6. Mutilated or Missing Warrant. If any Warrant
Certificate is lost, stolen, mutilated or destroyed, the Company shall issue and
the Warrant Agent shall countersign, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, upon receipt
of a proper affidavit or other evidence reasonably satisfactory to the Company
and the Warrant Agent (and surrender of any mutilated Warrant Certificate) and
bond of indemnity in form and amount and with corporate surety reasonably
satisfactory to the Company and the Warrant Agent in each instance protecting
the Company and the Warrant Agent, a new Warrant Certificate of like tenor and
representing an equivalent number of Warrants as the Warrant Certificate so
lost, stolen, mutilated or destroyed. Any such new Warrant Certificate shall
constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall be at
any time enforceable by anyone. An applicant for such substitute Warrant
Certificate shall also comply with such other reasonable regulations and pay
such other reasonable charges as the Company or the Warrant Agent may prescribe.
All Warrant Certificates shall be held and owned upon the express condition that
the foregoing provisions are exclusive with respect to the replacement of lost,
stolen, mutilated or destroyed Warrant Certificates, and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement of negotiable
instruments or other securities without their surrender.

                  Section 7. Reservation of Shares. The Company hereby agrees
that there shall be reserved for issuance and delivery upon exercise of Warrants
evidenced by this Warrant Certificate, free from preemptive rights, the number
of shares of authorized but unissued shares of Common Stock as shall be required
for issuance or delivery upon exercise of the Warrants evidenced by this Warrant
Certificate. The Company further agrees that it will not, by amendment of its
Certificate of Incorporation or through reorganization, consolidation, merger,
dissolution or sale of assets, or by any other voluntary act, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company. Without
limiting the generality of the foregoing, the Company agrees that before taking
any action which would cause an


                                      A-8
<PAGE>   29
adjustment reducing the Exercise Price below the then-par value of Warrant
Shares issuable upon exercise of the Warrants evidenced hereby, the Company
shall from time to time take all such action that may be necessary in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock at the Exercise Price as so adjusted.

                  Section 8. Exercise Price. The price per share (the "Exercise
Price") at which Warrant Shares shall be purchasable upon the exercise of the
Warrants evidenced by this Warrant Certificate shall be $17.75, subject to
adjustment pursuant to Section 9 hereof.

                  Section 9. Adjustment of Exercise Price and Number of Shares.
The number and kind of securities purchasable upon the exercise of the Warrants
evidenced by this Warrant Certificate and the Exercise Price thereof shall be
subject to adjustment from time to time after the date hereof upon the happening
of certain events, as follows:

                  9.1. Adjustments to Exercise Price. The Exercise Price shall
be subject to adjustment as follows:

                  (a) Stock Dividends. In case the Company after the date hereof
         shall pay a dividend or make a distribution to all holders of shares of
         Common Stock in shares of Common Stock, then in any such case the
         Exercise Price in effect at the opening of business on the day
         following the record date for the determination of stockholders
         entitled to receive such dividend or distribution shall be reduced to a
         price obtained by multiplying such Exercise Price by a fraction of
         which (x) the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on such record date and (y) the
         denominator shall be the sum of such number of shares of Common Stock
         outstanding and the total number of shares of Common Stock constituting
         such dividend or distribution, such reduction to become effective
         immediately after the opening of business on the day following such
         record date. For purposes of this subsection (a), the number of shares
         of Common Stock at any time outstanding shall not include shares held
         in the treasury of the Company but shall include shares issuable in
         respect of scrip certificates issued in lieu of fractions of shares of
         Common Stock. The Company will not pay any dividend or make any
         distribution on shares of Common Stock held in the treasury of the
         Company.

                  (b) Stock Splits and Reverse Splits. In case after the date
         hereof outstanding shares of Common Stock shall be subdivided into a
         greater number of shares of Common Stock, the Exercise Price in effect
         at the opening of business on the day following the day upon which such
         subdivision becomes effective shall be proportionately reduced, and,
         conversely, in case after the date hereof outstanding shares of Common
         Stock shall be combined into a smaller number of shares of Common
         Stock, the Exercise Price in effect at the opening of business


                                      A-9
<PAGE>   30
         on the day following the day upon which such combination becomes
         effective shall be proportionately increased, such reduction or
         increase, as the case may be, to become effective immediately after the
         opening of business on the day following the day upon which such
         subdivision or combination becomes effective.

                  (c) Issuances Below Market. In case the Company after the date
         hereof shall issue rights or warrants to holders of shares of Common
         Stock entitling them to subscribe for or purchase shares of Common
         Stock at a price per share less than the Closing Price per share on the
         record date for the determination of stockholders entitled to receive
         such rights or warrants, the Exercise Price in effect at the opening of
         business on the day following such record date shall be adjusted to a
         price obtained by multiplying such Exercise Price by a fraction of
         which (x) the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on such record date plus the
         number of shares of Common Stock that the aggregate offering price of
         the total number of shares so to be offered would purchase at such
         Closing Price and (y) the denominator shall be the number of shares of
         Common Stock outstanding at the close of business on such record date
         plus the number of additional shares of Common Stock so to be offered
         for subscription or purchase, such adjustment to become effective
         immediately after the opening of business on the day following such
         record date; provided, however, that no adjustment shall be made if the
         Company issues or distributes to each Warrantholder the rights or
         warrants that each Warrantholder would have been entitled to receive
         had the Warrants held by such Warrantholder been exercised prior to
         such record date; and provided, further, that in no event shall the
         fact that the Series B Warrants of the Company became exercisable for
         shares of Common Stock upon occurrence of the Shareholder Approval (as
         defined in the Investment Agreement) constitute an issuance of rights
         or warrants for purposes of this subsection (c). For purposes of this
         subsection (c), the number of shares of Common Stock at any time
         outstanding shall not include shares held in the treasury of the
         Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company shall not issue any rights or warrants in respect of shares of
         Common Stock held in the treasury of the Company. Rights or warrants
         issued by the Company to all holders of Common Stock entitling the
         holders thereof to subscribe for or purchase Equity Securities, which
         rights or warrants (i) are deemed to be transferred with such shares of
         Common Stock, (ii) are not exercisable and (iii) are also issued in
         respect of future issuances of Common Stock, including shares of Common
         Stock issued upon exercise of the Warrants evidenced by this Warrant
         Certificate, in each case in clauses (i) through (iii) until the
         occurrence of a specified event or events (a "Trigger Event"), shall
         for purposes of this subsection (c) not be deemed issued until the
         occurrence of the earliest Trigger Event.

<PAGE>   31
                  (d) Special Dividends. In case the Company after the date
         hereof shall distribute to all holders of shares of Common Stock
         evidences of its indebtedness or assets (excluding any regular periodic
         cash dividend), Equity Securities (other than Common Stock) or rights
         to subscribe (excluding those referred to in subsection (c) above) for
         Equity Securities other than Common Stock, in each such case the
         Exercise Price in effect immediately prior to the close of business on
         the record date for the determination of stockholders entitled to
         receive such distribution shall be adjusted to a price obtained by
         multiplying such Exercise Price by a fraction of which (x) the
         numerator shall be the Closing Price per share of Common Stock on such
         record date, less the then-current fair market value as of such record
         date (as determined by the Board of Directors in its good faith
         judgment) of the portion of assets or evidences of indebtedness or
         Equity Securities or subscription rights so distributed applicable to
         one share of Common Stock, and (y) the denominator shall be such
         Closing Price, such adjustment to become effective immediately prior to
         the opening of business on the day following such record date;
         provided, however, that no adjustment shall be made (1) if the Company
         issues or distributes to each Warrantholder the subscription rights
         referred to above that each Warrantholder would have been entitled to
         receive had the Warrants held by such Warrantholder been exercised
         prior to such record date or (2) if the Company grants to each
         Warrantholder the right to receive, upon the exercise of the Warrants
         held by such Warrantholder at any time after the distribution of the
         evidences of indebtedness or assets or Equity Securities referred to
         above, the evidences of indebtedness or assets or Equity Securities
         that such Warrantholder would have been entitled to receive had such
         Warrants been exercised prior to such record date. The Company shall
         provide any Warrantholder, upon receipt of a written request therefor,
         with any indenture or other instrument defining the rights of the
         holders of any indebtedness, assets, subscription rights or Equity
         Securities referred to in this subsection (d). Rights or warrants
         issued by the Company to all holders of Common Stock entitling the
         holders thereof to subscribe for or purchase Equity Securities, which
         rights or warrants (i) are deemed to be transferred with such shares of
         Common Stock, (ii) are not exercisable and (iii) are also issued in
         respect of future issuances of Common Stock, including shares of Common
         Stock issued upon exercise of the Warrants evidenced by this Warrant
         Certificate, in each case in clauses (i) through (iii) until the
         occurrence of a Trigger Event, shall for purposes of this subsection
         (d) not be deemed issued until the occurrence of the earliest Trigger
         Event.


                  (e) Tender or Exchange Offer. In case a tender or exchange
         offer made by the Company or any Subsidiary of the Company for all or
         any portion of the Common Stock shall be consummated and such tender
         offer shall involve an aggregate consideration having a fair market
         value (as determined by the Board of Directors in its good faith
         judgment) at the last time (the "Offer Time") tenders



                                      A-11
<PAGE>   32

         may be made pursuant to such tender or exchange offer (as it may be
         amended) that, together with the aggregate of the cash plus the fair
         market value (as determined by the Board of Directors in its good faith
         judgment), as of the Offer Time, of consideration payable in respect of
         any tender or exchange offer by the Company or any such Subsidiary for
         all or any portion of the Common Stock consummated preceding the Offer
         Time and in respect of which no Exercise Price adjustment pursuant to
         this subsection (e) has been made, exceeds 5% of the product of the
         Closing Price of the Common Stock at the Offer Time multiplied by the
         number of shares of Common Stock outstanding (including any tendered
         shares) at the Offer Time, the Exercise Price shall be reduced so that
         the same shall equal the price determined by multiplying the Exercise
         Price in effect immediately prior to the Offer Time by a fraction of
         which (x) the numerator shall be (i) the product of the Closing Price
         of the Common Stock at the Offer Time multiplied by the number of
         shares of Common Stock outstanding (including any tendered shares) at
         the Offer Time minus (ii) the fair market value (determined as
         aforesaid) of the aggregate consideration payable to stockholders based
         on the acceptance (up to any maximum specified in the terms of the
         tender or exchange offer) of all shares validly tendered and not
         withdrawn as of the Offer Time (the shares deemed so accepted, up to
         any such maximum, being referred to as the "Purchased Shares") and (y)
         the denominator shall be the product of (i) such Closing Price at the
         Offer Time multiplied by (ii) such number of outstanding shares at the
         Offer Time minus the number of Purchased Shares, such reduction to
         become effective immediately prior to the opening of business on the
         day following the Offer Time. For purposes of this subsection (e), the
         number of shares of Common Stock at any time outstanding shall not
         include shares held in the treasury of the Company but shall include
         shares issuable in respect of scrip certificates issued in lieu of
         fractions of shares of Common Stock.


                  (f) Closing Price Determination. For the purpose of any
         computation under subsections (c) and (d) of this Section 9.1, the
         Closing Price of Common Stock on any date shall be deemed to be the
         average of the Closing Prices for the five consecutive Trading Days
         ending not later than the day in question and commencing on a day
         selected at random in good faith by the Company which is not more than
         20 Trading Days before the day in question, provided, however, that (i)
         if the "ex" date for any event (other than the issuance or distribution
         requiring such computation) that requires an adjustment to the Exercise
         Price pursuant to this Section 9 occurs on or after the 20th Trading
         Day prior to the day in question and prior to the "ex" date for the
         issuance or distribution requiring such computation, the Closing Price
         for each Trading Day prior to the "ex" date for such other event shall
         be adjusted by multiplying such Closing Price by the same fraction
         which the Exercise Price is so required to be adjusted as a result of
         such other event, (ii) if the "ex" date for any event (other than the
         issuance or distribution requiring such computation) that requires an
         adjustment to the


                                      A-12
<PAGE>   33
         Exercise Price pursuant to this Section 9 occurs on or after the "ex"
         date for the issuance or distribution requiring such computation and on
         or prior to the day in question, the Closing Price for each Trading Day
         on and after the "ex" date for such other event shall be adjusted by
         multiplying such Closing Price by the reciprocal of the fraction by
         which the Exercise Price is so required to be adjusted as a result of
         such other event, and (iii) if the "ex" date for the issuance or
         distribution requiring such computation is on or prior to the day in
         question, after taking into account any adjustment required pursuant to
         clause (ii) of this proviso, the Closing Price for each Trading Day on
         or after such "ex" date shall be adjusted by adding thereto the fair
         market value on the day in question (as determined by the Board of
         Directors in a manner consistent with any determination of such value
         for the purposes of subsection (d) of this Section 9.1) of the assets,
         evidences of indebtedness, Equity Securities or subscription rights
         being distributed applicable to one share of Common Stock as of the
         close of business on the day before such "ex" date. For the purposes of
         any computation under subsection (e) of this Section 9.1, the Closing
         Price on any date shall be deemed to be the average of the daily
         Closing Prices for the five consecutive Trading Days ending not later
         than the Offer Time of such tender or exchange offer and commencing on
         a day selected at random in good faith by the Company which date shall
         be on or after the latest (the "Commencement Date") of (i) the date 20
         Trading Days before the date in question, (ii) the date of commencement
         of the tender or exchange offer requiring such computation and (iii)
         the date of the last amendment, if any, of such tender or exchange
         offer involving a change in the maximum number of shares for which
         tenders are sought or a change in the consideration offered; provided,
         however, that if the "ex" date for any event (other than the tender or
         exchange offer requiring such computation) that requires an adjustment
         to the Exercise Price pursuant to this Section 9 occurs on or after the
         Commencement Date and prior to the Offer Time for the tender or
         exchange offer requiring such computation, the Closing Price for each
         Trading Day prior to the "ex" date for such other event shall be
         adjusted by multiplying such Closing Price by the same fraction by
         which the Exercise Price is so required to be adjusted as a result of
         such other event. For purposes of this subsection (f), the term "ex"
         date, (i) when used with respect to any issuance or distribution, means
         the first date on which the Common Stock trades regular way on Nasdaq
         or on the relevant exchange or in the relevant market from which the
         Closing Price was obtained without the right to receive such issuance
         or distribution, (ii) when used with respect to any subdivision or
         combination of shares of Common Stock, means the first date on which
         the Common Stock trades regular way on Nasdaq or such exchange or in
         such market after the time at which such subdivision or combination
         becomes effective, and (iii) when used with respect to any tender or
         exchange offer means the first date on which the Common Stock trades
         regular way on Nasdaq or such exchange or in such market after the
         Offer Time of such tender or exchange offer.

<PAGE>   34
                  (g) Minimum Adjustment Requirement. No adjustment shall be
         required unless such adjustment would result in an increase or decrease
         of at least $0.01 in the Exercise Price then subject to adjustment;
         provided, however, that any adjustments that are not made by reason of
         this subsection (g) shall be carried forward and taken into account in
         any subsequent adjustment. In case the Company shall at any time issue
         shares of Common Stock by way of dividend on any stock of the Company
         or subdivide or combine the outstanding shares of Common Stock, said
         amount of $0.01 specified in the preceding sentence (as theretofore
         increased or decreased, if said amount shall have been adjusted in
         accordance with the provisions of this subsection (g)) shall forthwith
         be proportionately increased in the case of such a combination or
         decreased in the case of such a subdivision or stock dividend so as
         appropriately to reflect the same.

                  (h) Calculations. All calculations under this Section 9.1
         shall be made to the nearest $0.01.

                  (i) Certificate. Whenever an adjustment in the Exercise Price
         is made as required or permitted by the provisions of this Section 9.1,
         the Company shall promptly file with the Warrant Agent a certificate of
         its chief financial officer setting forth (A) the adjusted Exercise
         Price as provided in this Section 9.1 and a brief statement of the
         facts requiring such adjustment and the computation thereof and (B) the
         number of shares of Common Stock (or portions thereof) purchasable upon
         exercise of a Warrant after such adjustment in the Exercise Price in
         accordance with Section 9.2 hereof and the record date therefor, and
         promptly after such filing shall mail or cause to be mailed a notice of
         such adjustment to each Warrantholder at his or her last address as the
         same appears on the Warrant Register. Such certificate, in the absence
         of manifest error, shall be conclusive and final evidence of the
         correctness of such adjustment. The Warrant Agent shall be entitled to
         rely upon such certificate, and shall be under no duty or
         responsibility with respect to any such certificate except to exhibit
         the same to any Warrantholder desiring inspection thereof.

                  (j) Notice. In case:

                           (i) the Company shall declare any dividend or any
                  distribution of any kind or character (whether in cash,
                  securities or other property) on or in respect of shares of
                  Common Stock or to the stockholders of the Company (in their
                  capacity as such), excluding any regular periodic cash
                  dividend paid out of current or retained earnings (as such
                  terms are used in generally accepted accounting principles);

                           (ii) the Company shall authorize the granting to the
                  holders of shares of Common Stock of rights to subscribe for
                  or purchase any shares of capital stock or of any other right;
                  or

                           (iii) of any reclassification of shares of Common
                  Stock (other than a subdivision or combination of outstanding
                  shares of Common Stock), or of any consolidation or merger to
                  which the Company is a party and for which approval of any
                  stockholders of the Company is required, or of the sale or
                  transfer of all or substantially all of the assets of the
                  Company; or

                           (iv) of the voluntary or involuntary dissolution,
                  liquidation or winding up of the Company;

         then the Company shall cause to be filed with the Warrant Agent and
         shall mail or cause to be mailed to the Warrantholders, at their last
         addresses as they shall appear upon the Warrant Register, at least 30
         days prior to the applicable record date hereinafter specified, a
         notice stating (x) the date on which a record is to be taken for the
         purpose of such dividend, distribution or rights or, if a record is not
         to be taken, the date as of which the holders of shares of Common Stock
         of record to be entitled to such dividend, distribution or rights are
         to be determined or (y) the date on which such reclassification,
         consolidation, merger, sale, transfer, dissolution, liquidation or
         winding up is expected to become effective, and, if applicable, the
         date as of which it is expected that holders of shares of Common Stock
         of record shall be entitled to exchange their shares of Common Stock
         for securities or other property (including cash) deliverable upon such
         reclassification, consolidation, merger, sale, transfer, dissolution,
         liquidation or winding up. Failure to give any such notice, or any
         defect therein, shall not affect the validity of the proceedings
         referred to in clauses (i), (ii), (iii) and (iv) above.

                  (k) Section 305. Anything in this Section 9.1 to the contrary
         notwithstanding, the Company shall be entitled, but not required, to
         make such reductions in the Exercise Price, in addition to those
         required by this Section 9.1, as it in its discretion shall determine
         to be advisable, including, without limitation, in order that any
         dividend in or distribution of shares of Common Stock or shares of
         capital stock of any class other than Common Stock, subdivision,
         reclassification or combination of shares of Common Stock, issuance of
         rights or warrants, or any other transaction having a similar effect,
         shall not be treated as a distribution of property by the Company to
         its stockholders under Section 305 of the Internal Revenue Code of
         1986, as amended, or any successor provision and shall not be taxable
         to them.

                  (l) No Adjustment. Anything to the contrary herein
         notwithstanding, no adjustment to the Exercise Price or the number of
         shares of Common Stock


                                      A-15
<PAGE>   36
         purchasable upon exercise of a Warrant shall be made pursuant to this
         Section 9.1 or Section 9.2 hereof as a result of, or in connection
         with, the issuance of options or rights to purchase Common Stock issued
         to employees of the Company or its Subsidiaries pursuant to a stock
         option or other similar plan adopted by the Board of Directors or an
         employment agreement approved by the Board of Directors, or the
         modification, renewal or extension of any such plan or agreement if
         approved by the Board of Directors.

                  (m) When Adjustment Not Required. If the Company shall take a
         record of the holders of its Common Stock for purposes of taking any
         action that requires an adjustment of the Exercise Price under this
         Section 9, and shall, thereafter and before the effective date of such
         action, legally abandon its plan to take such action, then thereafter
         no adjustment shall be required by reason of the taking of such record
         and any such adjustment previously made in respect thereof shall be
         rescinded and annulled.

                  9.2. Adjustment to Number of Warrant Shares. Upon each
adjustment of the Exercise Price pursuant to Section 9.1 hereof the number of
Warrant Shares purchasable upon exercise of a Warrant outstanding prior to the
effectiveness of such adjustment shall be adjusted to the number, calculated to
the nearest one-hundredth of a share, obtained by (x) multiplying the number of
Warrant Shares purchasable immediately prior to such adjustment upon the
exercise of a Warrant by the Exercise Price in effect prior to such adjustment
and (y) dividing the product so obtained by the Exercise Price in effect after
such adjustment of the Exercise Price.

                  9.3. Organic Change.

                  (a) Company Survives. Upon the consummation of an Organic
Change (other than a transaction in which the Company is not the surviving
entity), lawful provision shall be made as part of the terms of such transaction
whereby the terms of the Warrant Certificates shall be modified, without payment
of any additional consideration therefor, so as to provide that upon exercise of
Warrants following the consummation of such Organic Change, the Warrantholders
of such Warrants shall have the right to purchase only the kind and amount of
securities, cash and other property receivable upon such Organic Change by a
holder of the number of Warrant Shares into which such Warrants might have been
exercised immediately prior to such Organic Change, assuming such holder of
Warrant Shares (i) is not a Person with which the Company consolidated or into
which the Company merged or which merged into the Company or to which a sale,
transfer or lease of all or substantially all of the assets of the Company was
made, as the case may be (a "Constituent Person"), or an Affiliate of a
Constituent Person, and (ii) failed to exercise his rights of election, if any,
as to the kind and amount of securities, cash and other property receivable upon
such Organic Change (provided that if the kind and amount of securities, cash
and other property receivable


                                      A-16
<PAGE>   37
upon such Organic Change is not the same for each share of Common Stock held
immediately prior to such Organic Change by others than a Constituent Person or
an Affiliate thereof and in respect of which such rights of election shall not
have been exercised ("non-electing shares"), then for the purpose of this
subsection (a) the kind and amount of securities, cash and other property
receivable upon such Organic Change by each non-electing share shall be deemed
to be the kind and amount so receivable per share by a plurality of the
non-electing shares); provided, however, that no adjustment shall be made as a
result of such Organic Change to the Exercise Price or the number of Warrant
Shares notwithstanding any provision of Section 9 hereof unless any event
requiring any such adjustment shall have occurred or shall occur prior to, upon
or after such Organic Change. Lawful provision also shall be made as part of the
terms of the Organic Change so that all other terms of the Warrant Certificates
shall remain in full force and effect following such an Organic Change. The
provisions of this Section 9.3(a) shall similarly apply to successive Organic
Changes.

                  (b) Company Does Not Survive. The Company shall not enter into
an Organic Change that is a transaction in which the Company is not the
surviving entity unless lawful provision shall be made as part of the terms of
such transaction whereby the surviving entity shall issue new securities to each
Warrantholder, without payment of any additional consideration therefor, with
terms that provide that upon the exercise of the Warrants, the Warrantholders of
such Warrants shall have the right to purchase only the kind and amount of
securities, cash and other property receivable upon such Organic Change by a
holder of the number of Warrant Shares into which such Warrants might have been
exercised immediately prior to such Organic Change, assuming such holder of
Warrant Shares (i) is not a Constituent Person or an Affiliate of a Constituent
Person and (ii) failed to exercise his rights of election, if any, as to the
kind and amount of securities, cash and other property receivable upon such
Organic Change (provided that if the kind and amount of securities, cash and
other property receivable upon such Organic Change is not the same for each
non-electing share, then for the purpose of this subsection (b) the kind and
amount of securities, cash and other property receivable upon such Organic
Change by each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares); provided,
however, that no adjustment shall be made as a result of such Organic Change to
the Exercise Price or the number of Warrant Shares notwithstanding any provision
of Section 9 hereof unless any event requiring any such adjustment shall have
occurred or shall occur prior to, upon or after such Organic Change. The
certificate or articles of incorporation or other constituent document of the
surviving entity shall provide for such adjustments which, for events subsequent
to the effective date of such certificate or articles of incorporation or other
constituent document, shall be equivalent to the adjustments provided for in
Section 9.1 hereof.

                  9.4. Statement on Warrants. The form of Warrant Certificate
need not be changed because of any adjustment made pursuant to Section 9.1 or
Section


                                      A-17
<PAGE>   38
9.2 hereof, and Warrants issued after such adjustment may state the same
Exercise Price and the same number of Warrant Shares as are stated in this
Warrant Certificate.

                  Section 10. Warrant Agent. The Company shall cause to be
appointed in the Borough of Manhattan, The City of New York, a Warrant Agent,
having a capital and surplus of at least $50,000,000. Initially, ChaseMellon
Shareholder Services, L.L.C. will act as Warrant Agent.


                  Section 11. Fractional Interests. The Company shall not be
required to issue Fractional Warrant Shares on the exercise of the Warrants
evidenced by this Warrant Certificate. If any Fractional Warrant Share would,
but for the provisions of this Section 11, be issuable on the exercise of the
Warrants evidenced by this Warrant Certificate (or specified portions thereof),
the Company shall pay an amount in cash equal to the fraction of a Warrant Share
represented by such Fractional Warrant Share multiplied by the Closing Price on
the day of such exercise.

                  Section 12. No Rights as Shareholder. Nothing in this Warrant
Certificate shall be construed as conferring upon the Warrantholder or its
transferees any rights as a shareholder of the Company, including the right to
vote, receive dividends, consent or receive notices as a shareholder with
respect to any meeting of shareholders for the election of directors of the
Company or any other matter.

                  Section 13. Successors. All the covenants and provisions of
this Warrant Certificate by or for the benefit of the Company or the
Warrantholder shall bind and inure to the benefit of their respective successors
and permitted assigns hereunder.

                  Section 14. Governing Law; Choice of Forum, Etc. The validity,
construction and performance of this Warrant Certificate shall be governed by,
and interpreted in accordance with, the laws of New York without reference to
its conflict of laws rules. The Company and the Warrantholder (the "parties
hereto") agree that the appropriate and exclusive forum for any disputes arising
out of this Warrant Certificate solely between or among any or all of the
Company, on the one hand, and the Investor and/or any Person who has become a
Warrantholder, on the other, shall be the United States District Court for the
Southern District of New York, and, if such court will not hear any such suit,
the courts of the state of the Company's incorporation, and the parties hereto
irrevocably consent to the exclusive jurisdiction of such courts, and agree to
comply with all requirements necessary to give such courts jurisdiction. The
parties hereto further agree that the parties will not bring suit with respect
to any disputes, except as expressly set forth below, arising out of this
Warrant Certificate for the execution or enforcement of judgment, in any
jurisdiction other than the above specified courts. Each of the parties hereto
irrevocably consents to the service of process in any action or proceeding
hereunder by the mailing of copies thereof by registered or certified airmail,

06611, Attention: General Counsel, or at such other address specified by the
Company in writing to the Warrant Agent, and (ii) any Warrantholder, at the
address of such Warrantholder specified in the Warrant Register. The foregoing
shall not limit the rights of any party hereto to serve process in any other
manner permitted by the law or to obtain execution of judgment in any other
jurisdiction. The parties further agree, to the extent permitted by law, that
final and unappealable judgment against any of them in any action or proceeding
contemplated above shall be conclusive and may be enforced in any other
jurisdiction within or outside the United States by suit on the judgment, a
certified or exemplified copy of which shall be conclusive evidence of the fact
and the amount of indebtedness. The parties agree to waive any and all rights
that they may have to a jury trial with respect to disputes arising out of this
Warrant Certificate.

                  Section 15. Benefits of this Warrant Certificate. Nothing in
this Warrant Certificate shall be construed to give to any Person other than the
Company and the Warrantholder any legal or equitable right, remedy or claim
under this Warrant Certificate, and this Warrant Certificate shall be for the
sole and exclusive benefit of the Company and the Warrantholder. This Warrant
Certificate shall not be valid or obligatory for any purpose until it shall have
been countersigned by the Warrant Agent.


                  Section 16. Other Obligations. The parties hereby acknowledge
that, pursuant to the Warrant Agreement, nothing in the Warrant Agreement shall
permit the Company or the Warrant Agent to authorize or take action that alters
or reduces the rights of the Existing Holders (as defined in the Warrant
Agreement) under the Investment Agreement or the Warrants. In the event of any
inconsistency between the provisions of the Warrant Agreement, on the one hand,
and this Warrant Certificate, on the other hand, the provisions of this Warrant
Certificate shall control. With respect to Existing Holders, in the case of any
inconsistency between the provisions of the Warrant Agreement, on the one hand,
and the Investment Agreement, on the other hand, the provisions of the
Investment Agreement shall control to the extent applicable, except that
Section 2.4 of the Warrant Agreement supersedes Section 8.10 of the Investment
Agreement, and Section 6.4(a) of the Warrant Agreement supersedes Section 10 of

connection with any exercise prior to May 13, 2000.

                  (b) On the terms and subject to the conditions set forth in
this Warrant Certificate, upon such presentation and surrender of this Warrant
Certificate and payment of such aggregate Exercise Price as set forth in
subsection (a) above, the Company shall promptly issue and cause to be delivered
to the Warrant Agent a certificate or certificates (in such name or names as the

to pay any such tax or other charge that may be imposed in connection with any
transfer involved in the issue of any certificate for Warrant Shares or other
securities or property, or payment of cash, to any Person other than the holder
of the Warrant Certificate surrendered upon exercise, and in case of any such
tax or charge, the Warrant Agent and the Company shall not be required to issue

Certificate is lost, stolen, mutilated or destroyed, the Company shall issue and
the Warrant Agent shall countersign, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, upon receipt
of a proper affidavit or other evidence reasonably satisfactory to the Company
and the Warrant Agent (and surrender of any mutilated Warrant Certificate) and
bond of indemnity in form and amount and with corporate surety reasonably
satisfactory to the Company and the Warrant Agent in each instance protecting
the Company and the Warrant Agent, a new Warrant Certificate of like tenor and
representing an equivalent number of Warrants as the Warrant Certificate so
lost, stolen, mutilated or destroyed. Any such new Warrant Certificate shall
constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall be at
any time enforceable by anyone. An applicant for such substitute Warrant
Certificate shall also comply with such other reasonable regulations and pay
such other reasonable charges as the Company or the Warrant Agent may prescribe.
All Warrant Certificates shall be held and owned upon the express condition that
the foregoing provisions are exclusive with respect to the replacement of lost,
stolen, mutilated or destroyed Warrant Certificates, and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement of negotiable
instruments or other securities without their surrender.

                  Section 7. Reservation of Shares. The Company hereby agrees
that there shall be reserved for issuance and delivery upon exercise of Warrants
evidenced by this Warrant Certificate, free from preemptive rights, the number
of shares of authorized but unissued shares of Common Stock as shall be required
for issuance or delivery upon exercise of the Warrants evidenced by this Warrant
Certificate. The Company further agrees that it will not, by amendment of its
Certificate of Incorporation or through reorganization, consolidation, merger,
dissolution or sale of assets, or by any other voluntary act, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company. Without
limiting the generality of the foregoing, the Company agrees that before taking
any action which would cause an adjustment reducing the Exercise Price below the
then-par value of Warrant Shares issuable upon exercise of the Warrants
evidenced hereby, the Company shall from time to time take all such action that
may be necessary in order that the Company may validly and legally issue fully
paid and nonassessable shares of Common Stock at the Exercise Price as so
adjusted.

of certain events, as follows:


                                       B-8
<PAGE>   52
                  9.1. Adjustments to Exercise Price. The Exercise Price shall
be subject to adjustment as follows:

                  (a) Stock Dividends. In case the Company after the date hereof
         shall pay a dividend or make a distribution to all holders of shares of
         Common Stock in shares of Common Stock, then in any such case the
         Exercise Price in effect at the opening of business on the day
         following the record date for the determination of stockholders
         entitled to receive such dividend or distribution shall be reduced to a
         price obtained by multiplying such Exercise Price by a fraction of
         which (x) the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on such record date and (y) the
         denominator shall be the sum of such number of shares of Common Stock
         outstanding and the total number of shares of Common Stock constituting
         such dividend or distribution, such reduction to become effective
         immediately after the opening of business on the day following such
         record date. For purposes of this subsection (a), the number of shares
         of Common Stock at any time outstanding shall not include shares held
         in the treasury of the Company but shall include shares issuable in
         respect of scrip certificates issued in lieu of fractions of shares of
         Common Stock. The Company will not pay any dividend or make any
         distribution on shares of Common Stock held in the treasury of the
         Company.

                  (b) Stock Splits and Reverse Splits. In case after the date
         hereof outstanding shares of Common Stock shall be subdivided into a
         greater number of shares of Common Stock, the Exercise Price in effect
         at the opening of business on the day following the day upon which such
         subdivision becomes effective shall be proportionately reduced, and,
         conversely, in case after the date hereof outstanding shares of Common
         Stock shall be combined into a smaller number of shares of Common
         Stock, the Exercise Price in effect at the opening of business on the
         day following the day upon which such combination becomes effective
         shall be proportionately increased, such reduction or increase, as the
         case may be, to become effective immediately after the opening of
         business on the day following the day upon which such subdivision or
         combination becomes effective.

                  (c) Issuances Below Market. In case the Company after the date
         hereof shall issue rights or warrants to holders of shares of Common
         Stock entitling them to subscribe for or purchase shares of Common
         Stock at a price per share less than the Closing Price per share on the
         record date for the determination of stockholders entitled to receive
         such rights or warrants, the Exercise Price in effect at the opening of
         business on the day following such record date shall be adjusted to a
         price obtained by multiplying such Exercise Price by a fraction of
         which (x) the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on such record date plus the
         number of shares of Common Stock that the aggregate offering price of
         the total number of shares so to be offered would purchase at such
         Closing Price and (y) the denominator shall be the number of shares of
         Common Stock outstanding at the close of business on such record date
         plus the number of additional shares of Common Stock so to be offered
         for


                                       B-9
<PAGE>   53
         subscription or purchase, such adjustment to become effective
         immediately after the opening of business on the day following such
         record date; provided, however, that no adjustment shall be made if the
         Company issues or distributes to each Warrantholder the rights or
         warrants that each Warrantholder would have been entitled to receive
         had the Warrants held by such Warrantholder been exercised prior to
         such record date; and provided, further, that in no event shall the
         fact that the Series B Warrants of the Company became exercisable for
         shares of Common Stock upon occurrence of the Shareholder Approval (as
         defined in the Investment Agreement) constitute an issuance of rights
         or warrants for purposes of this subsection (c). For purposes of this
         subsection (c), the number of shares of Common Stock at any time
         outstanding shall not include shares held in the treasury of the
         Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company shall not issue any rights or warrants in respect of shares of
         Common Stock held in the treasury of the Company. Rights or warrants
         issued by the Company to all holders of Common Stock entitling the
         holders thereof to subscribe for or purchase Equity Securities, which
         rights or warrants (i) are deemed to be transferred with such shares of
         Common Stock, (ii) are not exercisable and (iii) are also issued in
         respect of future issuances of Common Stock, including shares of Common
         Stock issued upon exercise of the Warrants evidenced by this Warrant
         Certificate, in each case in clauses (i) through (iii) until the
         occurrence of a specified event or events (a "Trigger Event"), shall
         for purposes of this subsection (c) not be deemed issued until the
         occurrence of the earliest Trigger Event.

                  (d) Special Dividends. In case the Company after the date
         hereof shall distribute to all holders of shares of Common Stock
         evidences of its indebtedness or assets (excluding any regular periodic
         cash dividend), Equity Securities (other than Common Stock) or rights
         to subscribe (excluding those referred to in subsection (c) above) for
         Equity Securities other than Common Stock, in each such case the
         Exercise Price in effect immediately prior to the close of business on
         the record date for the determination of stockholders entitled to
         receive such distribution shall be adjusted to a price obtained by
         multiplying such Exercise Price by a fraction of which (x) the
         numerator shall be the Closing Price per share of Common Stock on such
         record date, less the then-current fair market value as of such record
         date (as determined by the Board of Directors in its good faith
         judgment) of the portion of assets or evidences of indebtedness or
         Equity Securities or subscription rights so distributed applicable to
         one share of Common Stock, and (y) the denominator shall be such
         Closing Price, such adjustment to become effective immediately prior to
         the opening of business on the day following such record date;
         provided, however, that no adjustment shall be made (1) if the Company
         issues or distributes to each Warrantholder the subscription rights
         referred to above that each Warrantholder would have been entitled to
         receive had the Warrants held by such Warrantholder been exercised
         prior to such record date or (2) if the Company grants to each
         Warrantholder the right to receive, upon the exercise of the Warrants
         held by such Warrantholder at any time after the distribution of the
         evidences of indebtedness or assets or Equity Securities referred to
         above, the evidences of


                                      B-10
<PAGE>   54
         indebtedness or assets or Equity Securities that such Warrantholder
         would have been entitled to receive had such Warrants been exercised
         prior to such record date. The Company shall provide any Warrantholder,
         upon receipt of a written request therefor, with any indenture or other
         instrument defining the rights of the holders of any indebtedness,
         assets, subscription rights or Equity Securities referred to in this
         subsection (d). Rights or warrants issued by the Company to all holders
         of Common Stock entitling the holders thereof to subscribe for or
         purchase Equity Securities, which rights or warrants (i) are deemed to
         be transferred with such shares of Common Stock, (ii) are not
         exercisable and (iii) are also issued in respect of future issuances of
         Common Stock, including shares of Common Stock issued upon exercise of
         the Warrants evidenced by this Warrant Certificate, in each case in
         clauses (i) through (iii) until the occurrence of a Trigger Event,
         shall for purposes of this subsection (d) not be deemed issued until
         the occurrence of the earliest Trigger Event.


                  (e) Tender or Exchange Offer. In case a tender or exchange
         offer made by the Company or any Subsidiary of the Company for all or
         any portion of the Common Stock shall be consummated and such tender
         offer shall involve an aggregate consideration having a fair market
         value (as determined by the Board of Directors in its good faith
         judgment) at the last time (the "Offer Time") tenders may be made
         pursuant to such tender or exchange offer (as it may be amended) that,
         together with the aggregate of the cash plus the fair market value (as
         determined by the Board of Directors in its good faith judgment), as of
         the Offer Time, of consideration payable in respect of any tender or
         exchange offer by the Company or any such Subsidiary for all or any
         portion of the Common Stock consummated preceding the Offer Time and in
         respect of which no Exercise Price adjustment pursuant to this
         subsection (e) has been made, exceeds 5% of the product of the Closing
         Price of the Common Stock at the Offer Time multiplied by the number of
         shares of Common Stock outstanding (including any tendered shares) at
         the Offer Time, the Exercise Price shall be reduced so that the same
         shall equal the price determined by multiplying the Exercise Price in
         effect immediately prior to the Offer Time by a fraction of which (x)
         the numerator shall be (i) the product of the Closing Price of the
         Common Stock at the Offer Time multiplied by the number of shares of
         Common Stock outstanding (including any tendered shares) at the Offer
         Time minus (ii) the fair market value (determined as aforesaid) of the
         aggregate consideration payable to stockholders based on the acceptance
         (up to any maximum specified in the terms of the tender or exchange
         offer) of all shares validly tendered and not withdrawn as of the Offer
         Time (the shares deemed so accepted, up to any such maximum, being
         referred to as the "Purchased Shares") and (y) the denominator shall be
         the product of (i) such Closing Price at the Offer Time multiplied by
         (ii) such number of outstanding shares at the Offer Time minus the
         number of Purchased Shares, such reduction to become effective
         immediately prior to the opening of business on the day following the
         Offer Time. For purposes of this subsection (e), the number of shares
         of Common Stock at any time outstanding shall not include shares held
         in the treasury of the Company but shall include



                                      B-11
<PAGE>   55
         shares issuable in respect of scrip certificates issued in lieu of
         fractions of shares of Common Stock.

                  (f) Closing Price Determination. For the purpose of any
         computation under subsections (c) and (d) of this Section 9.1, the
         Closing Price of Common Stock on any date shall be deemed to be the
         average of the Closing Prices for the five consecutive Trading Days
         ending not later than the day in question and commencing on a day
         selected at random in good faith by the Company which is not more than
         20 Trading Days before the day in question, provided, however, that (i)
         if the "ex" date for any event (other than the issuance or distribution
         requiring such computation) that requires an adjustment to the Exercise
         Price pursuant to this Section 9 occurs on or after the 20th Trading
         Day prior to the day in question and prior to the "ex" date for the
         issuance or distribution requiring such computation, the Closing Price
         for each Trading Day prior to the "ex" date for such other event shall
         be adjusted by multiplying such Closing Price by the same fraction
         which the Exercise Price is so required to be adjusted as a result of
         such other event, (ii) if the "ex" date for any event (other than the
         issuance or distribution requiring such computation) that requires an
         adjustment to the Exercise Price pursuant to this Section 9 occurs on
         or after the "ex" date for the issuance or distribution requiring such
         computation and on or prior to the day in question, the Closing Price
         for each Trading Day on and after the "ex" date for such other event
         shall be adjusted by multiplying such Closing Price by the reciprocal
         of the fraction by which the Exercise Price is so required to be
         adjusted as a result of such other event, and (iii) if the "ex" date
         for the issuance or distribution requiring such computation is on or
         prior to the day in question, after taking into account any adjustment
         required pursuant to clause (ii) of this proviso, the Closing Price for
         each Trading Day on or after such "ex" date shall be adjusted by adding
         thereto the fair market value on the day in question (as determined by
         the Board of Directors in a manner consistent with any determination of
         such value for the purposes of subsection (d) of this Section 9.1) of
         the assets, evidences of indebtedness, Equity Securities or
         subscription rights being distributed applicable to one share of Common
         Stock as of the close of business on the day before such "ex" date. For
         the purposes of any computation under subsection (e) of this Section
         9.1, the Closing Price on any date shall be deemed to be the average of
         the daily Closing Prices for the five consecutive Trading Days ending
         not later than the Offer Time of such tender or exchange offer and
         commencing on a day selected at random in good faith by the Company
         which date shall be on or after the latest (the "Commencement Date") of
         (i) the date 20 Trading Days before the date in question, (ii) the date
         of commencement of the tender or exchange offer requiring such
         computation and (iii) the date of the last amendment, if any, of such
         tender or exchange offer involving a change in the maximum number of
         shares for which tenders are sought or a change in the consideration
         offered; provided, however, that if the "ex" date for any event (other
         than the tender or exchange offer requiring such computation) that
         requires an adjustment to the Exercise Price pursuant to this Section 9
         occurs on or after the Commencement Date and prior to the Offer Time
         for the tender or exchange offer requiring such computation, the
         Closing Price for each Trading Day prior to the "ex" date



                                      B-12
<PAGE>   56
         for such other event shall be adjusted by multiplying such Closing
         Price by the same fraction by which the Exercise Price is so required
         to be adjusted as a result of such other event. For purposes of this
         subsection (f), the term "ex" date, (i) when used with respect to any
         issuance or distribution, means the first date on which the Common
         Stock trades regular way on Nasdaq or on the relevant exchange or in
         the relevant market from which the Closing Price was obtained without
         the right to receive such issuance or distribution, (ii) when used with
         respect to any subdivision or combination of shares of Common Stock,
         means the first date on which the Common Stock trades regular way on
         Nasdaq or such exchange or in such market after the time at which such
         subdivision or combination becomes effective, and (iii) when used with
         respect to any tender or exchange offer means the first date on which
         the Common Stock trades regular way on Nasdaq or such exchange or in
         such market after the Offer Time of such tender or exchange offer.

                  (g) Minimum Adjustment Requirement. No adjustment shall be
         required unless such adjustment would result in an increase or decrease
         of at least $0.01 in the Exercise Price then subject to adjustment;
         provided, however, that any adjustments that are not made by reason of
         this subsection (g) shall be carried forward and taken into account in
         any subsequent adjustment. In case the Company shall at any time issue
         shares of Common Stock by way of dividend on any stock of the Company
         or subdivide or combine the outstanding shares of Common Stock, said
         amount of $0.01 specified in the preceding sentence (as theretofore
         increased or decreased, if said amount shall have been adjusted in
         accordance with the provisions of this subsection (g)) shall forthwith
         be proportionately increased in the case of such a combination or
         decreased in the case of such a subdivision or stock dividend so as
         appropriately to reflect the same.

                  (h) Calculations. All calculations under this Section 9.1
         shall be made to the nearest $0.01.

                  (i) Certificate. Whenever an adjustment in the Exercise Price
         is made as required or permitted by the provisions of this Section 9.1,
         the Company shall promptly file with the Warrant Agent a certificate of
         its chief financial officer setting forth (A) the adjusted Exercise
         Price as provided in this Section 9.1 and a brief statement of the
         facts requiring such adjustment and the computation thereof and (B) the
         number of shares of Common Stock (or portions thereof) purchasable upon
         exercise of a Warrant after such adjustment in the Exercise Price in
         accordance with Section 9.2 hereof and the record date therefor, and
         promptly after such filing shall mail or cause to be mailed a notice of
         such adjustment to each Warrantholder at his or her last address as the
         same appears on the Warrant Register. Such certificate, in the absence
         of manifest error, shall be conclusive and final evidence of the
         correctness of such adjustment. The Warrant Agent shall be entitled to
         rely upon such certificate, and shall be under no duty or
         responsibility with respect to any such certificate except to exhibit
         the same to any Warrantholder desiring inspection thereof.

                  (j) Notice. In case:

                           (a) the Company shall declare any dividend or any
                  distribution of any kind or character (whether in cash,
                  securities or other property) on or in respect of shares of
                  Common Stock or to the stockholders of the Company (in their
                  capacity as such), excluding any regular periodic cash
                  dividend paid out of current or retained earnings (as such
                  terms are used in generally accepted accounting principles);
                  or

                           (b) the Company shall authorize the granting to the
                  holders of shares of Common Stock of rights to subscribe for
                  or purchase any shares of capital stock or of any other right;
                  or

                           (c) of any reclassification of shares of Common Stock
                  (other than a subdivision or combination of outstanding shares
                  of Common Stock), or of any consolidation or merger to which
                  the Company is a party and for which approval of any
                  stockholders of the Company is required, or of the sale or
                  transfer of all or substantially all of the assets of the
                  Company; or

                           (d) of the voluntary or involuntary dissolution,
                  liquidation or winding up of the Company;

then the Company shall cause to be filed with the Warrant Agent and shall mail
or cause to be mailed to the Warrantholders, at their last addresses as they
shall appear upon the Warrant Register, at least 30 days prior to the applicable
record date hereinafter specified, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution or rights
or, if a record is not to be taken, the date as of which the holders of shares
of Common Stock of record to be entitled to such dividend, distribution or
rights are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is
expected to become effective, and, if applicable, the date as of which it is
expected that holders of shares of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities or other property
(including cash) deliverable upon such reclassification, consolidation, merger,
sale, transfer, dissolution, liquidation or winding up. Failure to give any such
notice, or any defect therein, shall not affect the validity of the proceedings
referred to in clauses (i), (ii), (iii) and (iv) above.

                  (k) Section 305. Anything in this Section 9.1 to the contrary
         notwithstanding, the Company shall be entitled, but not required, to
         make such reductions in the Exercise Price, in addition to those
         required by this Section 9.1, as it in its discretion shall determine
         to be advisable, including, without limitation, in order that any
         dividend in or distribution of shares of Common Stock or shares of
         capital stock of any class other than Common Stock, subdivision,
         reclassification or combination of shares of Common Stock, issuance of
         rights or warrants, or any other transaction having a similar effect,
         shall not be


                                      B-14
<PAGE>   58
         treated as a distribution of property by the Company to its
         stockholders under Section 305 of the Internal Revenue Code of 1986, as
         amended, or any successor provision and shall not be taxable to them.

                  (l) No Adjustment. Anything to the contrary herein
         notwithstanding, no adjustment to the Exercise Price or the number of
         shares of Common Stock purchasable upon exercise of a Warrant shall be
         made pursuant to this Section 9.1 or Section 9.2 hereof as a result of,
         or in connection with, the issuance of options or rights to purchase
         Common Stock issued to employees of the Company or its Subsidiaries
         pursuant to a stock option or other similar plan adopted by the Board
         of Directors or an employment agreement approved by the Board of
         Directors, or the modification, renewal or extension of any such plan
         or agreement if approved by the Board of Directors.

                  (m) When Adjustment Not Required. If the Company shall take a
         record of the holders of its Common Stock for purposes of taking any
         action that requires an adjustment of the Exercise Price under this
         Section 9, and shall, thereafter and before the effective date of such
         action, legally abandon its plan to take such action, then thereafter
         no adjustment shall be required by reason of the taking of such record
         and any such adjustment previously made in respect thereof shall be
         rescinded and annulled.

                  9.2. Adjustment to Number of Warrant Shares. Upon each
adjustment of the Exercise Price pursuant to Section 9.1 hereof the number of
Warrant Shares purchasable upon exercise of a Warrant outstanding prior to the
effectiveness of such adjustment shall be adjusted to the number, calculated to
the nearest one-hundredth of a share, obtained by (x) multiplying the number of
Warrant Shares purchasable immediately prior to such adjustment upon the
exercise of a Warrant by the Exercise Price in effect prior to such adjustment
and (y) dividing the product so obtained by the Exercise Price in effect after
such adjustment of the Exercise Price.

                  9.3. Organic Change.

                  (a) Company Survives. Upon the consummation of an Organic
Change (other than a transaction in which the Company is not the surviving
entity), lawful provision shall be made as part of the terms of such transaction
whereby the terms of the Warrant Certificates shall be modified, without payment
of any additional consideration therefor, so as to provide that upon exercise of
Warrants following the consummation of such Organic Change, the Warrantholders
of such Warrants shall have the right to purchase only the kind and amount of
securities, cash and other property receivable upon such Organic Change by a
holder of the number of Warrant Shares into which such Warrants might have been
exercised immediately prior to such Organic Change, assuming such holder of
Warrant Shares (i) is not a Person with which the Company consolidated or into
which the Company merged or which merged into the Company or to which a sale,
transfer or lease of all or substantially all of the assets of the Company was
made, as the case may be (a "Constituent Person"), or an Affiliate of a
Constituent Person, and (ii) failed to exercise his rights of election, if any,
as to the kind and amount of securities, cash and other property receivable upon
such Organic Change (provided that if the kind and amount of securities, cash
and other


                                      B-15
<PAGE>   59
property receivable upon such Organic Change is not the same for each share of
Common Stock held immediately prior to such Organic Change by others than a
Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non-electing shares"), then for the
purpose of this subsection (a) the kind and amount of securities, cash and other
property receivable upon such Organic Change by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares); provided, however, that no adjustment shall be made as a
result of such Organic Change to the Exercise Price or the number of Warrant
Shares notwithstanding any provision of Section 9 hereof unless any event
requiring any such adjustment shall have occurred or shall occur prior to, upon
or after such Organic Change. Lawful provision also shall be made as part of the
terms of the Organic Change so that all other terms of the Warrant Certificates
shall remain in full force and effect following such an Organic Change. The
provisions of this Section 9.3(a) shall similarly apply to successive Organic
Changes.

                  (b) Company Does Not Survive. The Company shall not enter into
an Organic Change that is a transaction in which the Company is not the
surviving entity unless lawful provision shall be made as part of the terms of
such transaction whereby the surviving entity shall issue new securities to each
Warrantholder, without payment of any additional consideration therefor, with
terms that provide that upon the exercise of the Warrants, the Warrantholders of
such Warrants shall have the right to purchase only the kind and amount of
securities, cash and other property receivable upon such Organic Change by a
holder of the number of Warrant Shares into which such Warrants might have been
exercised immediately prior to such Organic Change, assuming such holder of
Warrant Shares (i) is not a Constituent Person or an Affiliate of a Constituent
Person and (ii) failed to exercise his rights of election, if any, as to the
kind and amount of securities, cash and other property receivable upon such
Organic Change (provided that if the kind and amount of securities, cash and
other property receivable upon such Organic Change is not the same for each
non-electing share, then for the purpose of this subsection (b) the kind and
amount of securities, cash and other property receivable upon such Organic
Change by each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares); provided,
however, that no adjustment shall be made as a result of such Organic Change to
the Exercise Price or the number of Warrant Shares notwithstanding any provision
of Section 9 hereof unless any event requiring any such adjustment shall have
occurred or shall occur prior to, upon or after such Organic Change. The
certificate or articles of incorporation or other constituent document of the
surviving entity shall provide for such adjustments which, for events subsequent
to the effective date of such certificate or articles of incorporation or other
constituent document, shall be equivalent to the adjustments provided for in
Section 9.1 hereof.

                  9.4. Statement on Warrants. The form of Warrant Certificate
need not be changed because of any adjustment made pursuant to Section 9.1 or
Section 9.2


                                      B-16
<PAGE>   60
hereof, and Warrants issued after such adjustment may state the same Exercise
Price and the same number of Warrant Shares as are stated in this Warrant
Certificate.

                  Section 10. Warrant Agent. The Company shall cause to be
appointed in the Borough of Manhattan, The City of New York, a Warrant Agent,
having a capital and surplus of at least $50,000,000. Initially, ChaseMellon
Shareholder Services, L.L.C., will act as Warrant Agent.

                  Section 11. Fractional Interests. The Company shall not be
required to issue Fractional Warrant Shares on the exercise of the Warrants
evidenced by this Warrant Certificate. If any Fractional Warrant Share would,
but for the provisions of this Section 11, be issuable on the exercise of the
Warrants evidenced by this Warrant Certificate (or specified portions thereof),
the Company shall pay an amount in cash equal to the fraction of a Warrant Share
represented by such Fractional Warrant Share multiplied by the Closing Price on
the day of such exercise.

                  Section 12. No Rights as Shareholder. Nothing in this Warrant
Certificate shall be construed as conferring upon the Warrantholder or its
transferees any rights as a shareholder of the Company, including the right to
vote, receive dividends, consent or receive notices as a shareholder with
respect to any meeting of shareholders for the election of directors of the
Company or any other matter.

                  Section 13. Successors. All the covenants and provisions of
this Warrant Certificate by or for the benefit of the Company or the
Warrantholder shall bind and inure to the benefit of their respective successors
and permitted assigns hereunder.

                  Section 14. Governing Law; Choice of Forum, Etc. The validity,
construction and performance of this Warrant Certificate shall be governed by,
and interpreted in accordance with, the laws of New York without reference to
its conflict of laws rules. The Company and the Warrantholders (the "parties
hereto") agree that the appropriate and exclusive forum for any disputes arising
out of this Warrant Certificate solely between or among any or all of the
Company, on the one hand, and the Investor and/or any Person who has become a
Warrantholder, on the other, shall be the United States District Court for the
Southern District of New York, and, if such court will not hear any such suit,
the courts of the state of the Company's incorporation, and the parties hereto
irrevocably consent to the exclusive jurisdiction of such courts, and agree to
comply with all requirements necessary to give such courts jurisdiction. The
parties hereto further agree that the parties will not bring suit with respect
to any disputes, except as expressly set forth below, arising out of this
Warrant Certificate for the execution or enforcement of judgment, in any
jurisdiction other than the above specified courts. Each of the parties hereto
irrevocably consents to the service of process in any action or proceeding
hereunder by the mailing of copies thereof by registered or certified airmail,
postage prepaid, if to (i) the Company, at 48 Monroe Turnpike, Trumbull,CT
06611, Attention: General Counsel, or at such other address specified by the
Company in writing to the Warrant Agent, and (ii) any Warrantholder, at the
address of such Warrantholder specified in the Warrant Register.

Dear Sirs:


     In connection with the registration under the Securities Act of 1933 (the
"Act") of 277,629.157 shares of Series D Cumulative Preferred Stock, par value
$.01 per share (the "Series D Preferred"), of Oxford Health Plans, Inc., a
Delaware corporation (the "Company"); 132,808.069 shares of Series E  Cumulative
Preferred Stock, par value $.01 per share (the "Series E Preferred"), of the
Company; $277,629,157 principal amount of Series D Junior Subordinated
Debentures due May 13, 2008 (the "Series D Debentures") of the Company;
$132,808,069 principal amount of Series E Junior Subordinated Debentures due
May 13, 2008 (the "Series E Debentures") of the Company; 15,800,000 Series A
Warrants and 6,730,000 Series B Warrants (together the "Warrants") of the
Company, and the  22,530,000 shares of Common Stock, par value $.01 per share,
of the Company initially issuable upon exercise of the Warrants (the  "Shares")
(the Series D Preferred, the Series E Preferred, the Series D Debentures, the
Series E Debentures, the Warrants and the Shares collectively, the
"Securities"), we, as your counsel, have examined such corporate records,
certificates and other documents, and such questions of law, as we have
considered necessary or appropriate for the purposes of this opinion.



     Upon the basis of such examination, we advise you that, in our opinion,
when the registration statement on Form S-3 (File No. 333-77529), as amended
(the "Registration  Statement"), relating to the Securities has become
effective under the Act and the Securities have been duly issued and sold as
contemplated by the Registration Statement:



     (1) the Series D Preferred, the Series E Preferred and the Warrants will be
validly issued, fully paid and nonassessable, and the Shares, when duly issued
upon exercise of the Warrants, will be validly issued, fully paid and
nonassessable; and



     (2) when the Indenture relating to the Series D Debentures and the
Indenture relating to the Series E Debentures have been duly authorized,
executed and delivered, the terms of each of the Series D Debentures and the
Series E Debentures and of their issuance and sale have been duly established in
conformity with the applicable Indenture so as not to violate any applicable law
or result in a default under a breach of any agreement or instrument binding
upon the Company and so as to comply with any requirement or restriction imposed
by any court or governmental body having jurisdiction over the Company, the
Certificate of Incorporation of the Company has been amended in accordance with
the laws of the State of Delaware to confer the power to vote on holders of the
Series D Debentures and the Series E Debentures as contemplated by the
applicable Indenture, and the Series D Debentures and the Series E Debentures
have been duly executed, authenticated, issued and delivered in accordance with
the applicable Indenture, the Series D Debentures and the Series E Debentures
will constitute valid and legally binding obligations of the Company, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.



     The foregoing opinion is limited to the Federal laws of the United States
and the laws of the States of New York and Delaware, and we are expressing no
opinion as to the effect of the laws of any other jurisdiction.


     We have relied as to certain matters on information obtained from public
officials, officers of the Company and other sources believed by us to be
responsible.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Validity
of Securities" in the Prospectus. In giving such consent, we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Act.


                                             Very truly yours,


                                             /s/ Sullivan & Cromwell

* Earnings were insufficient to cover fixed charges and preference dividends by
  $642.9 million for the year ended December 31, 1998, $431.6 million for the
  year ended December 31, 1997 and $622.2 million for the nine months ended
  September 30, 1998.



     For purposes of computing these ratios, we increased our combined earnings
before income taxes, as reported in our annual report on Form 10-K/A No. 2 for
the year ended December 31, 1998, as amended by our Form 10-K/A No. 3, and in
our quarterly report on Form 10-Q for the quarter ended September 30, 1999, by
the amount of our fixed charges. We then divided the amount of earnings by the
amount of fixed charges and preference dividends, resulting in the ratio of
earnings to combined fixed charges and preference dividends. Fixed charges
represent interest expense plus the estimated interest factor in rental expense.
We have not capitalized interest in any period.
