     3.   DIVIDENDS.

          (a)  The holders of Class M Preferred Stock shall be entitled to
receive, when and as declared by the Board of Directors, out of funds legally
available for that purpose, quarterly cash dividends on the Class M Preferred
Stock in an amount per share equal to (i) during the period from the Issue Date

cash dividend paid or payable (determined on each Dividend Payment Date by
reference to the dividend most recently declared on the Class A Common Stock) on
the number of shares of Class A Common Stock (or portion thereof) into which a
share of Class M Preferred Stock is then convertible, and (ii) during the period
from and after January 13, 2003, the greater of $0.578125 or the quarterly cash
dividend paid or payable (determined on each Dividend Payment Date by reference
to the dividend most recently declared on the Class A Common Stock) on the
number of shares of Class A Common Stock (or portion thereof) into which a share
of Class M Preferred Stock is then convertible. Such dividends shall be
cumulative from the Issue Date, whether or not in any Dividend Period or Periods
such dividends shall be declared or there shall be funds of the Corporation
legally available for the payment of such dividends, and shall be payable
quarterly in arrears on each Dividend Payment Date, commencing on April 13,
2000. Each such dividend shall be payable in arrears to the holders of record of
the Class M Preferred Stock, as they appear on the stock records of the
Corporation at the close of business on the tenth Business Day immediately
preceding such Dividend Payment Date (each a "Record Date"). Accumulated,
accrued and unpaid dividends for any past Dividend Periods may be declared and
paid at any time, without reference to any regular Dividend Payment Date, to
holders of record on such date, which date shall not precede by more than 45
days the payment date thereof, as may be fixed by the Board of Directors.

          (b)  Any dividend payable on the Class M Preferred Stock for any
partial dividend period shall be computed ratably on the basis of twelve 30-day
months and a 360-day year. Holders of Class M Preferred Stock shall not be
entitled to any dividends, whether payable in cash, property or stock, in excess
of full cumulative dividends, as herein provided, on the Class M Preferred
Stock. No interest, or sum of money in lieu of interest, shall be payable in
respect of any dividend payment or payments on the Class M Preferred Stock that
may be in arrears.

          (c)  So long as any of the shares of Class M Preferred Stock are
outstanding, except as described in the immediately following sentence, no
dividends shall be declared or paid or set apart for payment by the Corporation
and no other distribution of cash or other property shall be declared or made,
directly or indirectly, by the Corporation with respect to any shares of Parity
Stock unless, in each case, dividends equal to the full amount of accumulated,
accrued and unpaid dividends on all outstanding shares of Class M Preferred
Stock have been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for payment of such dividends on the Class M Preferred Stock for all Dividend
Periods ending on or prior to the date such dividend or distribution is
declared, paid, set apart for payment or made, as the case may be, with respect
to such shares of Parity Stock. When dividends are not paid in full or a sum
sufficient for such payment is not set apart, as aforesaid, all dividends
declared upon the Class M Preferred Stock and all dividends declared upon any
shares of Parity

                                       7
<PAGE>   8
Stock shall be declared ratably in proportion to the respective amounts of
dividends accumulated, accrued and unpaid on the Class M Preferred Stock and
accumulated, accrued and unpaid on such Parity Stock.

          (d)  So long as any of the shares of Class M Preferred Stock are
outstanding, no dividends (other than dividends or distributions paid in shares
of, or options, warrants or rights to subscribe for or purchase shares of,
Junior Stock) shall be declared or paid or set apart for payment by the
Corporation and no other distribution of cash or other property shall be
declared or made, directly or indirectly, by the Corporation with respect to any
shares of Junior Stock, nor shall any shares of Junior Stock be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Stock made for purposes of an employee incentive or
benefit plan of the Corporation or any subsidiary) for any consideration (or any
moneys be paid to or made available for a sinking fund for the redemption of any
shares of any such stock), directly or indirectly, by the Corporation (except by
conversion into or exchange for shares of, or options, warrants or rights to
subscribe for or purchase shares of, Junior Stock), nor shall any other cash or
other property otherwise be paid or distributed to or for the benefit of any
holder of shares of Junior Stock in respect thereof, directly or indirectly, by
the Corporation unless, in each case, dividends equal to the full amount of all
accumulated, accrued and unpaid dividends on all outstanding shares of Class M
Preferred Stock have been declared and paid, or such dividends have been
declared and a sum sufficient for the payment thereof has been set apart for
such payment, on all outstanding shares of Class M Preferred Stock for all
Dividend Periods ending on or prior to the date such dividend or distribution is
declared, paid, set apart for payment or made with respect to such shares of
Junior Stock, or the date such shares of Junior Stock are redeemed, purchased or
otherwise acquired or monies paid to or made available for any sinking fund for
such redemption, or the date any such cash or other property is paid or
distributed to or for the benefit of any holders of Junior Stock in respect
thereof, as the case may be.

          Notwithstanding the provisions of this Section 3, the Corporation
shall not be prohibited from (i) declaring or paying or setting apart for
payment any dividend or distribution on any shares of Parity Stock or (ii)
redeeming, purchasing or otherwise acquiring any Parity Stock, in each case, if
such declaration, payment, redemption, purchase or other acquisition is
necessary in order to maintain the continued qualification of the Corporation as
a REIT under Section 856 of the Code.

     4.   LIQUIDATION PREFERENCE.

          (a)  In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, before any payment or
distribution by the Corporation (whether of capital, surplus or otherwise) shall
be made to or set apart for the holders of Junior Stock, the holders of shares
of Class M Preferred Stock shall be entitled to receive the greater of (i)
Twenty-Five Dollars ($25) per share of Class M Preferred Stock (the "Liquidation
Preference"), plus an amount equal to all dividends (whether or not earned or
declared) accumulated, accrued and unpaid thereon to the date of final
distribution to such holders, or (ii) the amount that would be payable to

                                       8
<PAGE>   9

the holders of Class M Preferred Stock if they had converted all outstanding
shares of Class M Preferred Stock into shares of Common Stock immediately prior
to such liquidation, dissolution or winding up; but such holders shall not be
entitled to any further payment. Until the holders of the Class M Preferred
Stock have been paid the Liquidation Preference in full, plus an amount equal to
all dividends (whether or not earned or declared) accumulated, accrued and
unpaid thereon to the date of final distribution to such holders, no payment
will be made to any holder of Junior Stock upon the liquidation, dissolution or
winding up of the Corporation. If, upon any liquidation, dissolution or winding
up of the Corporation, the assets of the Corporation, or proceeds thereof,
distributable among the holders of Class M Preferred Stock shall be insufficient
to pay in full the preferential amount aforesaid and liquidating payments on any
other shares of any class or series of Parity Stock, then such assets, or the
proceeds thereof, shall be distributed among the holders of Class M Preferred
Stock and any such other Parity Stock ratably in the same proportion as the
respective amounts that would be payable on such Class M Preferred Stock and any
such other Parity Stock if all amounts payable thereon were paid in full. For
the purposes of this Section 4, (i) a consolidation or merger of the Corporation
with one or more corporations, (ii) a sale or transfer of all or substantially
all of the Corporation's assets, or (iii) a statutory share exchange shall not
be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Corporation.

          (b)  Upon any liquidation, dissolution or winding up of the
Corporation, after payment shall have been made in full to the holders of Class
M Preferred Stock and any Parity Stock, as provided in Section 4(a), any other
series or class or classes of Junior Stock shall, subject to the respective
terms thereof, be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Class M Preferred Stock and any Parity Stock
shall not be entitled to share therein.

     5.   REDEMPTION AT THE OPTION OF THE CORPORATION.

          (a)  Shares of Class M Preferred Stock shall not be redeemable by the
Corporation prior to January 13, 2003, except as set forth in Section 11.2 of
this Article. On and after January 13, 2003, except as set forth in paragraph
(e) below, the Corporation, at its option, may redeem shares of Class M
Preferred Stock, in whole but not in part, at a redemption price payable in cash
equal to the Redemption Price applicable thereto. In the event of a redemption
of shares of Class M Preferred Stock, if the Redemption Date occurs after a
dividend record date and on or prior to the related Dividend Payment Date, the
dividend payable on such Dividend Payment Date in respect of such shares called
for redemption shall be payable on such Dividend Payment Date to the holders of
record at the close of business on such dividend record date notwithstanding the
redemption of such shares, and shall not be payable as part of the redemption
price for such shares.

          (b)  The Redemption Date shall be selected by the Corporation, shall
be specified in the notice of redemption and shall be not less than 30 days nor
more than 60 days after the date notice of redemption is sent by the
Corporation.

                                       9
<PAGE>   10

          (c)  If full cumulative dividends on all outstanding shares of Class M
Preferred Stock have not been declared and paid, or declared and set apart for
payment, no shares of Class M Preferred Stock may be redeemed unless all
outstanding shares of Class M Preferred Stock are simultaneously redeemed.
Neither the Corporation nor any affiliate of the Corporation may purchase or
acquire shares of Class M Preferred Stock, otherwise than pursuant to a purchase
or exchange offer made on the same terms to all holders of shares of Class M
Preferred Stock.

          (d)  If the Corporation shall redeem shares of Class M Preferred Stock
pursuant to paragraph (a) of this Section 5, notice of such redemption shall be
given to each holder of record of the shares to be redeemed. Such notice shall
be provided by first class mail, postage prepaid, at such holder's address as
the same appears on the stock records of the Corporation. Neither the failure to
mail any notice required by this paragraph (d), nor any defect therein or in the
mailing thereof to any particular holder, shall affect the sufficiency of the
notice or the validity of the proceedings for redemption with respect to the
other holders. Any notice which has been mailed in the manner herein provided
shall be conclusively presumed to have been duly given on the date mailed
whether or not the holder receives the notice. Each such notice shall state, as
appropriate: (i) the Redemption Date; (ii) the place or places at which
certificates for such shares are to be surrendered for cash; and (iii) the
redemption price payable on such Redemption Date, including, without limitation,
a statement as to whether or not accumulated, accrued and unpaid dividends will
be payable as part of the redemption price, or payable on the next Dividend
Payment Date to the record holder at the close of business on the relevant
record date as described in the next succeeding sentence. Notice having been
mailed as aforesaid, from and after the Redemption Date (unless the Corporation
shall fail to make available the amount of cash necessary to effect such
redemption), (i) dividends on the shares of Class M Preferred Stock so called
for redemption shall cease to accumulate or accrue on the shares of Class M
Preferred Stock called for redemption, (ii) said shares shall no longer be
deemed to be outstanding, and (iii) all rights of the holders thereof as holders
of Class M Preferred Stock of the Corporation shall cease except the right to
receive the cash payable upon such redemption, without interest thereon, upon
surrender of their certificates if so required; provided, however, that if the
Redemption Date for any shares of Class M Preferred Stock occurs after any
dividend record date and on or prior to the related Dividend Payment Date, the
full dividend payable on such Dividend Payment Date in respect of such shares of
Class M Preferred Stock called for redemption shall be payable on such Dividend
Payment Date to the holders of record of such shares at the close of business on
the corresponding dividend record date notwithstanding the prior redemption of
such shares. The Corporation's obligation to make available the cash necessary
to effect such redemption in accordance with the preceding sentence shall be
deemed fulfilled if, on or before the applicable Redemption Date, the
Corporation shall irrevocably deposit in trust with a bank or trust company
(which may not be an affiliate of the Corporation) that has, or is an affiliate
of a bank or trust company that has, a capital and surplus of at least
$50,000,000, such amount of cash as is necessary for such redemption plus, if
such Redemption Date occurs after any dividend record date and on or prior to
the related Dividend Payment Date, such amount of cash as is necessary to pay
the dividend payable on such Dividend Payment Date in respect of such shares of
Class M Preferred Stock called for redemption, with irrevocable instructions
that such cash be applied to the redemption of the shares of Class M Preferred
Stock so

                                       10
<PAGE>   11

called for redemption and, if applicable, the payment of such dividend. No
interest shall accrue for the benefit of the holders of shares of Class M
Preferred Stock to be redeemed on any cash so set aside by the Corporation.
Subject to applicable escheat laws, any such cash unclaimed at the end of two
years from the Redemption Date shall revert to the general funds of the
Corporation, after which reversion the holders of shares of Class M Preferred
Stock so called for redemption shall look only to the general funds of the
Corporation for the payment of such cash.

     As promptly as practicable after the surrender in accordance with such
notice of the certificates for any such shares of Class M Preferred Stock to be
so redeemed (properly endorsed or assigned for transfer, if the Corporation
shall so require and the notice shall so state), such certificates shall be
exchanged for cash (without interest thereon) for which such shares have been
redeemed in accordance with such notice.

     6.   STATUS OF REACQUIRED STOCK.

     All shares of Class M Preferred Stock that have been issued and reacquired
in any manner by the Corporation (including, without limitation, shares of Class
M Preferred Stock which have been surrendered for conversion) shall be returned
to the status of authorized but unissued shares of Class M Preferred Stock.

     7.   CONVERSION.

     7.1  CONVERSION AT HOLDERS' OPTION.

     At any time on or after the Issue Date, except as set forth in Section
7.2(i) of this Article, holders of shares of Class M Preferred Stock shall have
the right to convert all or a portion of such shares into shares of Class A
Common Stock, as follows:

          (a)  Subject to and upon compliance with the provisions of this
Section 7, each share of Class M Preferred Stock shall, at the option of the
holder thereof, be convertible at any time (unless such share is called for
redemption, then to and including but not after the close of business on the
date immediately prior to the Redemption Date, unless the Corporation shall
default in payment due upon redemption thereof), into that number of fully paid
and non-assessable shares of Class A Common Stock (calculated as to each
conversion to the nearest 1/100th of a share) obtained by dividing $25 by the
Conversion Price in effect at such time and by surrender of the certificate
representing such shares to be converted in the manner provided in subsection
(b) of this Section 7.1.

          (b)  In order to convert shares of Class M Preferred Stock, the holder
of the shares to be converted shall surrender the certificate representing such
shares at any office or agency maintained by the Corporation for such purpose,
accompanied by the funds, if any, required by the last paragraph of this
subsection (b) to be paid by such holder, and shall give written notice of
conversion in the form provided on such certificate representing shares of Class
M Preferred Stock (or such other notice as is acceptable to the Corporation) to
the Corporation at such office or agency

                                       11
<PAGE>   12

that the holder elects to convert the shares of Class M Preferred Stock
specified in such notice. Such notice shall also state the name or names,
together with address or addresses, in which the certificate or certificates for
shares of Class A Common Stock which shall be issuable in such conversion shall
be issued. Unless the shares issuable on conversion are to be issued in the same
name as the name in which such share of Class M Preferred Stock is registered,
each certificate representing a share of Class M Preferred Stock surrendered for
conversion shall be accompanied by instruments of transfer, in form satisfactory
to the Corporation, duly executed by the holder or such holder's duly authorized
attorney and an amount sufficient to pay any transfer or similar tax (or
evidence reasonably satisfactory to the Corporation that such taxes have been
paid) .

          As promptly as practicable after the surrender of certificates
representing such shares of Class M Preferred Stock and the receipt of such
notice, instruments of transfer and funds, if any, as aforesaid, the Corporation
shall issue and shall deliver at such office or agency to such holder, or as
designated in such holder's written instructions, a certificate or certificates
for the number of full shares of Class A Common Stock issuable upon the
conversion of such share or shares of Class M Preferred Stock in accordance with
provisions of this Section 7, and a check or cash in respect of (i) the cash
amount payable to such holder, if any, referred to in the last paragraph of this
subsection (b), and (ii) any fractional interest in a share of Class A Common
Stock arising upon such conversion, as provided in paragraph (c) of this Section
7.1.

          Each conversion shall be deemed to have been effected immediately
prior to the close of business on the date on which certificates representing
such shares of Class M Preferred Stock shall have been surrendered and such
notice (and any applicable instruments of transfer and any required taxes)
received by the Corporation as aforesaid, and the Person or Persons in whose
name or names any certificate or certificates for shares of Class A Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby at such time on such
date, and such conversion shall be at the Conversion Price in effect at such
time on such date, unless the stock transfer books of the Corporation shall be
closed on that date, in which event such Person or Persons shall be deemed to
have become such holder or holders of record at the close of business on the
next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date on which such
shares shall have been surrendered and such notice received by the Corporation.

          Except as provided herein, the Corporation will make no payment or
allowance for unpaid dividends, whether or not in arrears, on converted shares
or for dividends (other than dividends on the Class A Common Stock the record
date for which is after the conversion date and which the Corporation shall pay
in the ordinary course to the record holder as of the record date) on the Class
A Common Stock issued upon such conversion. Holders of Class M Preferred Stock
at the close of business on a Record Date will be entitled to receive an amount
equal to the dividend payable on such shares on the corresponding Dividend
Payment Date notwithstanding the conversion of such shares following such Record
Date. In addition to any such dividend, if the Dividend Adjustment Amount (as
defined below) with respect to any shares of Class M Preferred Stock surrendered
for conversion is positive, the holders of such shares shall, as of the date of
conversion,

                                       12
<PAGE>   13

be entitled to receive a cash payment equal to the Dividend Adjustment Amount.
If the Dividend Adjustment Amount with respect to any shares of Class M
Preferred Stock surrendered for conversion is negative, such shares must be
accompanied by payment of a cash amount equal to the absolute value of the
Dividend Adjustment Amount. As used herein, the "Dividend Adjustment Amount"
shall mean, with respect to any share of Class M Preferred Stock that has been
surrendered for conversion, the sum of:

          (i) the aggregate amount of any dividends (whether or not earned or
     declared) that are accumulated, accrued and unpaid on such share as of the
     time of such conversion; minus

          (ii) if such share has been surrendered for conversion during the
     period between the close of business on any Record Date and the opening of
     business on the corresponding Dividend Payment Date, the amount of the
     dividend payable thereon on such Dividend Payment Date; minus

          (iii) an amount equal to the product of (A) the number (which may be a
     fraction) of shares of Class A Common Stock into which a share of Class M
     Preferred Stock is then convertible, multiplied by (B) the quarterly cash
     dividend per share that was most recently declared on the Class A Common
     Stock, determined as of the date of conversion, and if the date of such
     conversion is not a record date for the payment of a dividend on the Class
     A Common Stock, multiplied by (C) a fraction, the numerator of which is the
     number of days in the period from and including the date of the most recent
     record date for the payment of a dividend on the Class A Common Stock to
     but excluding the date of such conversion, and the denominator of which is
     90.

          (c)  No fractional shares of Class A Common Stock or scrip
representing fractions of a share of Class A Common Stock shall be issued upon
conversion of shares of Class M Preferred Stock. If more than one share of Class
M Preferred Stock shall be surrendered for conversion at one time by the same
holder, the number of full shares of Class A Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares of Class M Preferred Stock so surrendered. In lieu of any fractional
interest in a share of Class A Common Stock that would otherwise be deliverable
upon the conversion of any share of Class M Preferred Stock, the Corporation
shall pay to the holder of such shares an amount in cash (computed to the
nearest cent) equal to the Closing Price of the Class A Common Stock on the
Trading Day immediately preceding the date of conversion, multiplied by the
fractional interest that otherwise would have been deliverable upon conversion
of such share.

     7.2  ADJUSTMENTS TO CONVERSION PRICE

          (a)  The Conversion Price shall be adjusted from time to time as
follows:

               (i) If the Corporation shall after the Issue Date (A) pay a
dividend or make a distribution on its Class A Common Stock in shares of Class A
Common Stock, (B) subdivide its

                                       13
<PAGE>   14

outstanding shares of Class A Common Stock into a greater number of shares, (C)
combine its outstanding shares of Class A Common Stock into a smaller number of
shares or (D) issue any shares of capital stock by reclassification of its
outstanding Class A Common Stock, then, in each such case, the Conversion Price
in effect immediately prior to such action shall be adjusted so that the holder
of any share of Class M Preferred Stock thereafter surrendered for conversion
shall be entitled to receive the number of shares of Class A Common Stock or
other capital stock of the Corporation which such holder would have owned or
been entitled to receive immediately following such action had such share been
converted immediately prior to the occurrence of such event. An adjustment made
pursuant to this subsection (i) of this Section 7.2(a) shall become effective
immediately after the record date, in the case of a dividend or distribution, or
immediately after the effective date, in the case of a subdivision, combination
or reclassification. If, as a result of an adjustment made pursuant to this
subsection (i), the holder of any share of Class M Preferred Stock thereafter
surrendered for conversion shall become entitled to receive shares of two or
more classes of capital stock or shares of Class A Common Stock and other
capital stock of the Corporation, the Board of Directors (whose determination
shall be conclusive and shall be described in a statement filed by the
Corporation with the Transfer Agent) shall determine the allocation of the
adjusted Conversion Price between or among shares of such classes of capital
stock or shares of Class A Common Stock and other capital stock.

               (ii) If the Corporation shall, after the Issue Date, issue
rights, options or warrants to all holders of its outstanding shares of Class A
Common Stock entitling them (for a period expiring within 45 days after the
record date described below) to subscribe for or purchase shares of Class A
Common Stock at a price per share less than the current market price per share
(determined pursuant to subsection (iv) of this Section 7.2(a)) of the Class A
Common Stock (other than pursuant to any stock option, restricted stock or other
incentive or benefit plan or stock ownership or purchase plan for the benefit of
employees, directors or officers or any dividend reinvestment plan of the
Corporation in effect at the time hereof or any other similar plan adopted or
implemented hereafter), then the Conversion Price in effect immediately prior
thereto shall be adjusted so that it shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to the record date
by a fraction, the numerator of which shall be the sum of (A) the number of
shares of Class A Common Stock outstanding on the record date and (B) the number
of shares which the aggregate proceeds to the Corporation from the exercise of
such rights, options or warrants for Class A Common Stock would purchase at such
current market price, and the denominator of which shall be the sum of (A) the
number of shares of Class A Common Stock outstanding on the record date and (B)
the number of additional shares of Class A Common Stock offered for subscription
or purchase pursuant to such rights, options or warrants. Such adjustment shall
be made successively whenever any rights, options or warrants are issued, and
shall become effective immediately after the record date for the determination
of stockholders entitled to receive such rights, options or warrants; provided,
however, that if all of the shares of Class A Common Stock offered for
subscription or purchase are not delivered upon the exercise of such rights,
options or warrants, upon the expiration of such rights, options or warrants,
the Conversion Price shall be readjusted to the Conversion Price which would
have been in effect had the numerator and the denominator of the foregoing
fraction and the resulting adjustment been made based upon the number of shares
of Class A Common Stock actually delivered upon the exercise of such rights,
options or warrants rather than upon the

                                       14
<PAGE>   15

number of shares of Class A Common Stock offered for subscription or purchase.
In determining whether any rights, options or warrants entitle the holders to
subscribe for or purchase shares of Class A Common Stock at less than such
current market price, and in determining the aggregate offering price of such
shares of Class A Common Stock, there shall be taken into account any
consideration received by the Corporation for such rights, options or warrants,
with the value of such consideration, if other than cash, determined by the
Board of Directors (whose determination shall be conclusive and shall be
described in a statement filed by the Corporation with the Transfer Agent).

               (iii) In case the Corporation shall, by dividend or otherwise,
distribute to all holders of its outstanding Class A Common Stock any capital
stock (other than Class A Common Stock), evidences of its indebtedness or assets
or rights or warrants to subscribe for or purchase securities of the Corporation
(excluding (A) those referred to in subsections (i) and (ii) of this Section
7.2(a), (B) dividends and distributions paid in cash out of the retained
earnings of the Corporation, and (C) distributions upon mergers or
consolidations to which subsection (b) of this Section 7.2 applies), then, in
each such case, the Conversion Price shall be adjusted to equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the record date of such distribution by a fraction, the numerator of which shall
be the current market price per share (determined pursuant to subsection (iv) of
this Section 7.2(a)) of the Class A Common Stock, less the fair market value on
such record date (determined by the Board or Directors, whose determination
shall be conclusive and shall be described in a statement filed by the
Corporation with the Transfer Agent) of the portion of the capital stock or
assets or the evidences of indebtedness or assets so distributed to the holder
of one share of Class A Common Stock or of such subscription rights or warrants
applicable to one share of Class A Common Stock, and the denominator of which
shall be such current market price per share of Class A Common Stock. Such
adjustment shall become effective immediately after the record date for the
determination of stockholders entitled to receive such distribution.

               (iv) For the purpose of any computation under subsections (ii)
and (iii) of this Section 7.2(a), the current market price per share of Class A
Common Stock on any date shall be the average of the Closing Price of the Class
A Common Stock for the shorter of (A) 10 consecutive Trading Days ending on the
last full Trading Day prior to the Time of Determination or (B) the period
commencing on the date next succeeding the first public announcement of the
issuance of such rights or warrants or such distribution through such last full
Trading Day prior to the Time of Determination. For purposes of the foregoing,
the term "Time of Determination" shall mean the time and date of the earlier of
(A) the record date for determining stockholders entitled to receive the rights,
warrants or distribution referred to in subsections (ii) and (iii) of this
Section 7.2, or (B) the commencement of "ex-dividend" trading on the exchange or
market referred to in the definition of "Closing Price."

               (v) No adjustment in the Conversion Price shall be required to be
made unless such adjustment would require an increase or decrease of at least
one percent of such price,

                                       15
<PAGE>   16

provided, however, that any adjustment which by reason of this subsection (v) is
not required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Section 7.2 shall be made to
the nearest cent or to the nearest 1/100th of a share, as the case may be.
Anything in this Section 7.2 to the contrary notwithstanding, the Corporation
shall be entitled to make such reduction in the Conversion Price, in addition to
those required by this Section 7.2, as it shall determine in its discretion to
be advisable in order that any stock dividend, subdivision of shares,
distribution of rights to purchase stock or securities, or distribution of
securities convertible into or exchangeable for stock hereafter made by the
Corporation to its stockholders shall not be taxable to the recipients. Except
as set forth in subsections (i), (ii) and (iii) above, the Conversion Price
shall not be adjusted for the issuance of Class A Common Stock, or any
securities convertible into or exchangeable for Class A Common Stock or carrying
the right to purchase any of the foregoing, in exchange for cash, property or
services.

               (vi) The Corporation from time to time may decrease the
Conversion Price by any amount for any period of time if the period is at least
20 days and if the decrease is irrevocable during the period. Whenever the
Conversion Price is so decreased, the Corporation shall mail to holders of
record of shares of Class M Preferred Stock a notice of the decrease at least 15
days before the date the decreased Conversion Price takes effect, and such
notice shall state the decreased Conversion Price and the period it will be in
effect.

          (b)  Notwithstanding any other provision herein to the contrary, in
case of any merger or consolidation to which the Corporation is a party (other
than a merger or consolidation in which the Corporation is the continuing entity
and in which the Class A Common Stock outstanding immediately prior to the
merger or consolidation is not exchanged for cash, or the securities or other
property of another entity), or in the case of any sale or transfer of all or
substantially all of the Corporation's property and assets to another entity,
there will be no adjustment of the Conversion Price, and lawful provision shall
be made by the entity formed by such consolidation or the entity whose
securities, cash or other property will immediately after the merger or
consolidation be owned, by virtue of the merger or consolidation, by the holders
of Class A Common Stock immediately prior to the merger or consolidation, or the
entity which shall have acquired such assets of the Corporation, such that each
share of Class M Preferred Stock then outstanding will, without the consent of
the holder thereof, become convertible into the kind and amount of securities,
cash or other property receivable upon such merger, consolidation, sale or
transfer by a holder of the number of shares of Class A Common Stock into which
such share of Class M Preferred Stock was convertible immediately prior to such
merger, consolidation, sale or transfer (without regard to any Ownership
Restrictions as defined in Article IV of the Charter) assuming such holder of
Class A Common Stock did not exercise his rights of election, if any, as to the
kind or amount of securities, cash or other property receivable upon such
merger, consolidation, sale or transfer. In the case of a cash merger of the
Corporation into another entity or any other cash transaction of the type
mentioned in this Section 7.2(b), each share of Class M Preferred Stock will
thereafter be convertible at the Conversion Price in effect at such time into
the same amount of cash per share into which each share of Class M Preferred
Stock would have been convertible had (without regard to any Ownership
Restrictions as defined in Article IV of the

                                       16
<PAGE>   17

Charter) such share been converted into Class A Common Stock immediately prior
to the effective date of such cash merger or other transaction. The foregoing
provisions of this Section 7.2(b) shall similarly apply to successive mergers,
consolidations, sales or transfers.

               (c)  If (i) the Corporation shall take any action that would
require an adjustment in the Conversion Price pursuant to Section 7.2; (ii) the
Corporation shall authorize the granting to the holders of the Class A Common
Stock generally of rights or warrants to subscribe for or purchase any shares of
stock of any class or series or of any other rights or warrants; (iii) there
shall be any reorganization or reclassification of the Class A Common Stock
(other than an event to which subsection (i) of Section 7.2(a) applies) or any
consolidation or merger to which the Corporation is a party or any sale or
transfer of all or substantially all of the assets of the Corporation, in each
case, for which approval of any stockholders of the Corporation is required; or
(iv) there shall be a voluntary or involuntary liquidation, dissolution or
winding up of the Corporation; then, in each such case, the Corporation shall
cause to be given to the holders of shares of Class M Preferred Stock and the
Transfer Agent as promptly as possible, but in any event at least 15 days prior
to the applicable date hereinafter specified, a notice stating (i) the date on
which a record is to be taken for the purpose of such action or granting of
rights or warrants, or, if a record is not to be taken, the date as of which the
holders of Class A Common Stock of record to be entitled to such dividend,
distribution, rights or warrants are to be determined, or (ii) the date on which
such reorganization, reclassification, consolidation, merger, sale, transfer,
liquidation, dissolution or winding up is expected to become effective or occur,
and the date as of which it is expected that holders of Class A Common Stock of
record shall be entitled to exchange their shares of Class A Common Stock for
securities, cash or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution or winding up. Failure to give such notice or any defect therein
shall not affect the legality or validity of the proceedings described in this
Section 7.2(c).

               (d)  Whenever the Conversion Price is adjusted as herein
provided, (i) the Corporation shall promptly file with the Transfer Agent a
certificate setting forth the Conversion Price after such adjustment and a brief
statement of the facts requiring such adjustment and the manner of computing the
same, which certificate shall be conclusive evidence of the correctness of such
adjustment, and (ii) the Corporation shall mail or cause to be mailed by first
class mail, postage prepaid, as soon as practicable to each holder of record of
shares of Class M Preferred Stock a notice stating that the Conversion Price has
been adjusted and setting forth the adjusted Conversion Price and the effective
date thereof.

               (e)  In any case in which paragraph (a) of this Section 7.2 shall
require that an adjustment be made immediately following a record date or an
effective date, the Corporation may elect to defer (but only until the filing by
the Corporation with the Transfer Agent of the certificate required by
subsection 7.2(d)) (i) issuing to the holder of any share of Class M Preferred
Stock converted after such record date or effective date the shares of Class A
Common Stock issuable upon such conversion in excess of the shares of Class A
Common Stock issuable upon such conversion on the basis of the Conversion Price
prior to adjustment, and (ii) paying to such holder any amount of cash in lieu
of a fractional share.

                                       17
<PAGE>   18

               (f)  In the event that at any time, as a result of an adjustment
made pursuant to subsection (i) of Section 7.2(a), the holder of any share of
Class M Preferred Stock thereafter surrendered for conversion shall become
entitled to receive any shares of the Corporation other than shares of Class A
Common Stock, thereafter the Conversion Price of such other shares so receivable
upon conversion of any share of Class M Preferred Stock shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to Class A Common Stock contained in
this Section 7.2.

               (g)  The Corporation shall at all times reserve and keep
available, free from preemptive rights, out of the aggregate of its authorized
but unissued shares of Class A Common Stock, for the purpose of effecting
conversion of shares of Class M Preferred Stock, the full number of shares of
Class A Common Stock deliverable upon the conversion of all outstanding shares
of Class M Preferred Stock not theretofore converted and on or before (and as a
condition of) taking any action that would cause an adjustment of the Conversion
Price resulting in an increase in the number of shares of Class A Common Stock
deliverable upon conversion in excess of the number thereof previously reserved
and available therefor, the Corporation shall take all such action so required.
For purposes of this paragraph (g), the number of shares of Class A Common Stock
which shall be deliverable upon the conversion of all outstanding shares of
Class M Preferred Stock shall be computed as if at the time of computation all
such outstanding shares of Class M Preferred Stock were held by a single holder
(and without regard to the Ownership Limit).

     Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value (if any) of the shares of Class A
Common Stock deliverable upon conversion of the shares of Class M Preferred
Stock, the Corporation shall take any corporate action which may, in the opinion
of its counsel, be necessary in order that the Corporation may validly and
legally issue fully paid and non-assessable shares of Class A Common Stock at
such adjusted Conversion Price.

               (h)  The Corporation will pay any and all documentary stamp,
issue or transfer taxes, and any other similar taxes, payable in respect of the
issue or delivery of shares of Class A Common Stock upon conversion of shares of
Class M Preferred Stock pursuant hereto; provided, however, that the Corporation
shall not be required to pay any tax that may be payable in respect of any
transfer involved in the issue or delivery of shares of Class A Common Stock in
a name other than that of the holder of the shares of Class M Preferred Stock to
be converted, and no such issue or delivery shall be made unless and until the
Person requesting such issue or delivery has paid to the Corporation the amount
of any such tax or established, to the reasonable satisfaction of the
Corporation, that such tax has been paid.

               (i)  Notwithstanding anything to the contrary contained in this
Section 7, conversion of Class M Preferred Stock pursuant to this Section 7
shall be permitted only to the extent that such conversion would not result in a
violation of the Ownership Restrictions (as defined in Article IV of the
Charter), after taking into account any applicable waivers. This limitation
shall

                                       18
<PAGE>   19

not, however, be taken into account in determining any amounts to which the
holders of any shares of Class M Preferred Stock may be entitled under Sections
3, 4 or 5.

               (j)  If the Corporation shall take any action affecting the Class
A Common Stock, other than an action described in this Section 7, that in the
opinion of the Board of Directors would materially adversely affect the
conversion rights of the holders of Class M Preferred Stock, the Board of
Directors may, but shall have no obligation to, adjust the Conversion Price for
the Class M Preferred Stock to the extent permitted by law in such manner, if
any, and at such time as the Board of Directors, in its sole discretion, may
determine to be equitable under the circumstances.

     8.   RANKING.

     Any class or series of capital stock of the Corporation shall be deemed to
rank:

          (a)  prior or senior to the Class M Preferred Stock, as to the payment
of dividends and as to distribution of assets upon liquidation, dissolution or
winding up, if the holders of such class or series shall be entitled to the
receipt of dividends and of amounts distributable upon liquidation, dissolution
or winding up, as the case may be, in preference or priority to the holders of
Class M Preferred Stock ("Senior Stock");

          (b)  on a parity with the Class M Preferred Stock, as to the payment
of dividends and as to distribution of assets upon liquidation, dissolution or
winding up, whether or not the dividend rates, dividend payment dates or
redemption or liquidation prices per share thereof be different from those of
the Class M Preferred Stock, if (i) such capital stock is Class B Cumulative
Convertible Preferred Stock, Class C Cumulative Preferred Stock, Class D
Cumulative Preferred Stock, Class G Cumulative Preferred Stock, Class H
Cumulative Preferred Stock, Class I Cumulative Preferred Stock, Class J
Cumulative Convertible Preferred Stock, Class K Convertible Cumulative Preferred
Stock or Class L Convertible Cumulative Preferred Stock of the Corporation, or
(ii) the holders of such class of stock or series and the Class M Preferred
Stock shall be entitled to the receipt of dividends and of amounts distributable
upon liquidation, dissolution or winding up in proportion to their respective
amounts of accrued and unpaid dividends per share or liquidation preferences,
without preference or priority of one over the other (the capital stock referred
to in clauses (i) and (ii) of this paragraph being hereinafter referred to,
collectively, as "Parity Stock"); and

          (c)  junior to the Class M Preferred Stock, as to the payment of
dividends and as to the distribution of assets upon liquidation, dissolution or
winding up, if (i) such capital stock or series shall be Common Stock or (ii)
the holders of Class M Preferred Stock shall be entitled to receipt of dividends
or of amounts distributable upon liquidation, dissolution or winding up, as the
case may be, in preference or priority to the holders of shares of such class or
series (the capital stock referred to in clauses (i) and (ii) of this paragraph
being hereinafter referred to, collectively, as "Junior Stock").

                                       19
<PAGE>   20

     9.   Voting.

          (a)  If and whenever six quarterly dividends (whether or not
consecutive) payable on the Class M Preferred Stock shall be in arrears (which
shall, with respect to any such quarterly dividend, mean that any such dividend
has not been paid in full), whether or not earned or declared, the number of
directors then constituting the Board of Directors shall be increased by two (if
not already increased by reason of similar types of provisions with respect to
shares of Parity Stock of any other class or series which is entitled to similar
voting rights (the "Voting Preferred Stock")) and the holders of shares of Class
M Preferred Stock, together with the holders of shares of all other Voting
Preferred Stock then entitled to exercise similar voting rights, voting as a
single class regardless of series, shall be entitled to elect the two additional
directors to serve on the Board of Directors at any annual meeting of
stockholders or special meeting held in place thereof, or at a special meeting
of the holders of the Class M Preferred Stock and the Voting Preferred Stock
called as hereinafter provided. Whenever all arrears in dividends on the Class M
Preferred Stock and the Voting Preferred Stock then outstanding shall have been
paid and dividends thereon for the current quarterly dividend period shall have
been declared and paid, or declared and set apart for payment, then the right of
the holders of the Class M Preferred Stock and the Voting Preferred Stock to
elect such additional two directors shall cease (but subject always to the same
provision for the vesting of such voting rights in the case of any similar
future arrearages), and the terms of office of all persons elected as directors
by the holders of the Class M Preferred Stock and the Voting Preferred Stock
shall forthwith terminate and the number of directors constituting the Board of
Directors shall be reduced accordingly. At any time after such voting power
shall have been so vested in the holders of Class M Preferred Stock and the
Voting Preferred Stock, if applicable, the Secretary of the Corporation may, and
upon the written request of any holder of Class M Preferred Stock (addressed to
the Secretary at the principal office of the Corporation) shall, call a special
meeting of the holders of the Class M Preferred Stock and of the Voting
Preferred Stock for the election of the two directors to be elected by them as
herein provided, such call to be made by notice similar to that provided in the
Bylaws of the Corporation for a special meeting of the stockholders or as
required by law. If any such special meeting required to be called as above
provided shall not be called by the Secretary within 20 days after receipt of
any such request, then any holder of Class M Preferred Stock may call such
meeting, upon the notice above provided, and for that purpose shall have access
to the stock books of the Corporation. The directors elected at any such special
meeting shall hold office until the next annual meeting of the stockholders or
special meeting held in lieu thereof if such office shall not have previously
terminated as above provided. If any vacancy shall occur among the directors
elected by the holders of the Class M Preferred Stock and the Voting Preferred
Stock, a successor shall be elected by the Board of Directors, upon the
nomination of the then-remaining director elected by the holders of the Class M
Preferred Stock and the Voting Preferred Stock or the successor of such
remaining director, to serve until the next annual meeting of the stockholders
or special meeting held in place thereof if such office shall not have
previously terminated as provided above.

          (b)  So long as any shares of Class M Preferred Stock are outstanding,
in addition to any other vote or consent of stockholders required by law or by
the Charter of the Corporation,

                                       20
<PAGE>   21

the affirmative vote of at least 66-2/3% of the votes entitled to be cast by the
holders of the Class M Preferred Stock voting as a single class, given in person
or by proxy, either in writing without a meeting or by vote at any meeting
called for the purpose, shall be necessary for effecting or validating:

               (i)  Any amendment, alteration or repeal of any of the provisions
of, or the addition of any provision to, these Articles Supplementary, the
Charter or the By-Laws of the Corporation that materially adversely affects the
voting powers, rights or preferences of the holders of the Class M Preferred
Stock; provided, however, that the amendment of the provisions of the Charter so
as to authorize or create, or to increase the authorized amount of, or issue any
Junior Stock or any shares of any class of Parity Stock shall not be deemed to
materially adversely affect the voting powers, rights or preferences of the
holders of Class M Preferred Stock; or

               (ii) The authorization, creation of, increase in the authorized
amount of, or issuance of any shares of any class or series of Senior Stock or
any security convertible into shares of any class or series of Senior Stock
(whether or not such class or series of Senior Stock is currently authorized);

provided, however, that no such vote of the holders of Class M Preferred Stock
shall be required if, at or prior to the time when such amendment, alteration or
repeal is to take effect, or when the issuance of any such Senior Stock or
convertible or exchangeable security is to be made, as the case may be,
provision is made for the redemption of all shares of Class M Preferred Stock at
the time outstanding to the extent such redemption is authorized by Section 5 of
this Article.

     For purposes of the foregoing provisions and all other voting rights under
these Articles Supplementary, each share of Class M Preferred Stock shall have
one (1) vote per share, except that when any other class or series of preferred
stock of the Corporation shall have the right to vote with the Class M Preferred
Stock as a single class on any matter, then the Class M Preferred Stock and such
other class or series shall have with respect to such matters one quarter of one
vote per $25 of stated liquidation preference. Except as otherwise required by
applicable law or as set forth herein or in the Charter, the Class M Preferred
Stock shall not have any relative, participating, optional or other special
voting rights and powers other than as set forth herein, and the consent of the
holders thereof shall not be required for the taking of any corporate action.

     10.  RECORD HOLDERS.

     The Corporation and the Transfer Agent may deem and treat the record holder
of any share of Class M Preferred Stock as the true and lawful owner thereof for
all purposes, and neither the Corporation nor the Transfer Agent shall be
affected by any notice to the contrary.

                                       21

     11.1 RESTRICTIONS ON OWNERSHIP AND TRANSFERS.

          (A)  LIMITATION ON BENEFICIAL OWNERSHIP. Except as provided in Section
11.8, from and after the Issue Date, no Person (other than the Initial Holder or
a Look-Through Entity) shall Beneficially Own shares of Class M Preferred Stock
in excess of the Ownership Limit, the Initial Holder shall not Beneficially Own
shares of Class M Preferred Stock in excess of the Initial Holder Limit and no
Look-Through Entity shall Beneficially Own shares of Class M Preferred Stock in
excess of the Look-Through Ownership Limit.

          (B)  TRANSFERS IN EXCESS OF OWNERSHIP LIMIT. Except as provided in
Section 11.8, from and after the Issue Date (and subject to Section 11.12), any
Transfer (whether or not such Transfer is the result of transactions entered
into through the facilities of the NYSE or other securities exchange or an
automated inter-dealer quotation system) that, if effective, would result in any
Person (other than the Initial Holder or a Look-Through Entity) Beneficially
Owning shares of Class M Preferred Stock in excess of the Ownership Limit shall
be void ab initio as to the Transfer of such shares of Class M Preferred Stock
that would be otherwise Beneficially Owned by such Person in excess of the
Ownership Limit, and the intended transferee shall acquire no rights in such
shares of Class M Preferred Stock.

          (C)  TRANSFERS IN EXCESS OF INITIAL HOLDER LIMIT. Except as provided
in Section 11.8, from and after the Issue Date (and subject to Section 11.12),
any Transfer (whether or not such Transfer is the result of transactions entered
into through the facilities of the NYSE or other securities exchange or an
automated inter-dealer quotation system) that, if effective, would result in the
Initial Holder Beneficially Owning shares of Class M Preferred Stock in excess
of the Initial Holder Limit shall be void ab initio as to the Transfer of such
shares of Class M Preferred Stock that would be otherwise Beneficially Owned by
the Initial Holder in excess of the Initial Holder limit, and the Initial Holder
shall acquire no rights in such shares of Class M Preferred Stock.

          (D)  TRANSFERS IN EXCESS OF LOOK-THROUGH OWNERSHIP LIMIT. Except as
provided in Section 11.8 from and after the Issue Date (and subject to Section
11.12), any Transfer (whether or not such Transfer is the result of transactions
entered into through the facilities of the NYSE or other securities exchange or
an automated inter-dealer quotation system) that, if effective, would result in
any Look-Through Entity Beneficially Owning shares of Class M Preferred Stock in
excess of the Look-Through Ownership limit shall be void ab initio as to the
Transfer of such shares of Class M Preferred Stock that would be otherwise
Beneficially Owned by such Look-Through Entity in excess of the Look-Through
Ownership Limit and such Look-Through Entity shall acquire no rights in such
shares of Class M Preferred Stock.

          (E)  TRANSFERS RESULTING IN "CLOSELY HELD" STATUS. From and after the
Issue Date, any Transfer that, if effective would result in the Corporation
being "closely held" within the meaning of Section 856(h) of the Code, or would
otherwise result in the Corporation failing to qualify as a REIT (including,
without limitation, a Transfer or other event that would result in the
Corporation owning (directly or constructively) an interest in a tenant that is
described in Section 856(d)(2)(B) of the Code if the income derived by the
Corporation from such tenant would cause the Corporation to fail to satisfy any
of the gross income requirements of Section 856(c) of the Code)

                                       22
<PAGE>   23

shall be void ab initio as to the Transfer of shares of Class M Preferred Stock
that would cause the Corporation (i) to be "closely held" within the meaning of
Section 856(h) of the Code or (ii) otherwise fail to qualify as a REIT, as the
case may be, and the intended transferee shall acquire no rights in such shares
of Class M Preferred Stock.

          (F)  SEVERABILITY ON VOID TRANSACTIONS. A Transfer of a share of Class
M Preferred Stock that is null and void under Sections 11.1(B), (C), (D), or (E)
of this Article because it would, if effective, result in (i) the ownership of
Class M Preferred Stock in excess of the Initial Holder Limit, the Ownership
Limit, or the Look-Through Ownership Limit, (ii) the Corporation being "closely
held" within the meaning of Section 856(h) of the Code or (iii) the Corporation
otherwise failing to qualify as a REIT, shall not adversely affect the validity
of the Transfer of any other share of Class M Preferred Stock in the same or any
other related transaction.

     11.2 REMEDIES FOR BREACH. If the Board of Directors or a committee thereof
shall at any time determine in good faith that a Transfer or other event has
taken place in violation of Section 11.1 of this Article or that a Person
intends to acquire or has attempted to acquire Beneficial Ownership of any
shares of Class M Preferred Stock in violation of Section 11.1 of this Article
(whether or not such violation is intended), the Board of Directors or a
committee thereof shall be empowered to take any action as it deems advisable to
refuse to give effect to or to prevent such Transfer or other event, including,
but not limited to, refusing to give effect to such Transfer or other event on
the books of the Corporation, causing the Corporation to redeem such shares at
the then current Market Price and upon such terms and conditions as may be
specified by the Board of Directors in its sole discretion (including, but not
limited to, by means of the issuance of long-term indebtedness for the purpose
of such redemption), demanding the repayment of any distributions received in
respect of shares of Class M Preferred Stock acquired in violation of Section
11.1 of this Article or instituting proceedings to enjoin such Transfer or to
rescind such Transfer or attempted Transfer; provided, however, that any
Transfers or attempted Transfers (or, in the case of events other than a
Transfer, Beneficial Ownership) in violation of Section 11.1 of this Article,
regardless of any action (or non-action) by the Board of Directors or such
committee, (a) shall be void ab initio or (b) shall automatically result in the
transfer described in Section 11.3 of this Article; provided, further, that the
provisions of this Section 11.2 shall be subject to the provisions of Section
11.12 of this Article; provided, further, that neither the Board of Directors
nor any committee thereof may exercise such authority in a manner that
interferes with any ownership or transfer of Class M Preferred Stock that is
expressly authorized pursuant to Section 11.8(C) of this Article.

     11.3. TRANSFER IN TRUST.

          (A)  ESTABLISHMENT OF TRUST. If, notwithstanding the other provisions
contained in this Article, at any time after the Issue Date there is a purported
Transfer (an "Excess Transfer") (whether or not such Transfer is the result of
transactions entered into through the facilities of the NYSE or other securities
exchange or an automated inter-dealer quotation system) or other change in the
capital structure of the Corporation (including, but not limited to, any
redemption of Equity Stock) or other event (including, but not limited to, any
acquisition of any share of Equity Stock)

                                       23
<PAGE>   24

such that (a) any Person (other than the Initial Holder or a Look-Through
Entity) would Beneficially Own shares of Class M Preferred Stock in excess of
the Ownership Limit, or (b) the Initial Holder would Beneficially Own shares of
Class M Preferred Stock in excess of the Initial Holder Limit, or (c) any Person
that is a Look-Through Entity would Beneficially Own shares of Class M Preferred
Stock in excess of the Look-Through Ownership Limit (in any such event, the
Person, Initial Holder or Look-Through Entity that would Beneficially Own shares
of Class M Preferred Stock in excess of the Ownership Limit, the Initial Holder
Limit or the Look-Through Entity Limit, respectively, is referred to as a
"Prohibited Transferee"), then, except as otherwise provided in Section 11.8 of
this Article, such shares of Class M Preferred Stock in excess of the Ownership
Limit, the Initial Holder Limit or the Look-Through Ownership Limit, as the case
may be, (rounded up to the nearest whole share) shall be automatically
transferred to a Trustee in his capacity as trustee of a Trust for the exclusive
benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee
shall be deemed to be effective as of the close of business on the Business Day
prior to the Excess Transfer, change in capital structure or another event
giving rise to a potential violation of the Ownership Limit, the Initial Holder
Limit or the Look-Through Entity Ownership Limit.

          (B)  APPOINTMENT OF TRUSTEE. The Trustee shall be appointed by the
Corporation and shall be a Person unaffiliated with either the Corporation or
any Prohibited Transferee. The Trustee may be an individual or a bank or trust
company duly licensed to conduct a trust business.

          (C)  STATUS OF SHARES HELD BY THE TRUSTEE. Shares of Class M Preferred
Stock held by the Trustee shall be issued and outstanding shares of capital
stock of the Corporation. Except to the extent provided in Section 11.3(E), the
Prohibited Transferee shall have no rights in the Class M Preferred Stock held
by the Trustee, and the Prohibited Transferee shall not benefit economically
from ownership of any shares held in trust by the Trustee, shall have no rights
to dividends and shall not possess any rights to vote or other rights
attributable to the shares held in the Trust.

          (D)  DIVIDEND AND VOTING RIGHTS. The Trustee shall have all voting
rights and rights to dividends with respect to shares of Class M Preferred Stock
held in the Trust, which rights shall be exercised for the benefit of the
Charitable Beneficiary. Any dividend or distribution paid prior to the discovery
by the Corporation that the shares of Class M Preferred Stock have been
transferred to the Trustee shall be repaid to the Corporation upon demand, and
any dividend or distribution declared but unpaid shall be rescinded as void ab
initio with respect to such shares of Class M Preferred Stock. Any dividends or
distributions so disgorged or rescinded shall be paid over to the Trustee and
held in trust for the Charitable Beneficiary. Any vote cast by a Prohibited
Transferee prior to the discovery by the Corporation that the shares of Class M
Preferred Stock have been transferred to the Trustee will be rescinded as void
ab initio and shall be recast in accordance with the desires of the Trustee
acting for the benefit of the Charitable Beneficiary. The owner of the shares at
the time of the Excess Transfer, change in capital structure or other event
giving rise to a potential violation of the Ownership Limit, Initial Holder
Limit or Look-Through Entity Ownership Limit shall be deemed to have given an
irrevocable proxy to the Trustee to vote the shares of Class M Preferred Stock
for the benefit of the Charitable Beneficiary.

                                       24
<PAGE>   25

          (E)  RESTRICTIONS ON TRANSFER. The Trustee of the Trust may sell the
shares held in the Trust to a Person, designated by the Trustee, whose ownership
of the shares will not violate the Ownership Restrictions. If such a sale is
made, the interest of the Charitable Beneficiary shall terminate and proceeds of
the sale shall be payable to the Prohibited Transferee and to the Charitable
Beneficiary as provided in this Section 11.3(E). The Prohibited Transferee shall
receive the lesser of (1) the price paid by the Prohibited Transferee for the
shares or, if the Prohibited Transferee did not give value for the shares
(through a gift, devise or other transaction), the Market Price of the shares on
the day of the event causing the shares to be held in the Trust and (2) the
price per share received by the Trustee from the sale or other disposition of
the shares held in the Trust. Any proceeds in excess of the amount payable to
the Prohibited Transferee shall be payable to the Charitable Beneficiary. If any
of the transfer restrictions set forth in this Section 11.3(E) or any
application thereof is determined in a final judgment to be void, invalid or
unenforceable by any court having jurisdiction over the issue, the Prohibited
Transferee may be deemed, at the option of the Corporation, to have acted as the
agent of the Corporation in acquiring the Class M Preferred Stock as to which
such restrictions would, by their terms, apply, and to hold such Class M
Preferred Stock on behalf of the Corporation.

          (F)  PURCHASE RIGHT IN STOCK TRANSFERRED TO THE TRUSTEE. Shares of
Class M Preferred Stock transferred to the Trustee shall be deemed to have been
offered for sale to the Corporation, or its designee, at a price per share equal
to the lesser of (i) the price per share in the transaction that resulted in
such transfer to the Trust (or, in the case of a devise or gift, the Market
Price at the time of such devise or gift) and (ii) the Market Price on the date
the Corporation, or its designee, accepts such offer. The Corporation shall have
the right to accept such offer for a period of 90 days after the later of (i)
the date of the Excess Transfer or other event resulting in a transfer to the
Trust and (ii) the date that the Board of Directors determines in good faith
that an Excess Transfer or other event occurred.

          (G)  DESIGNATION OF CHARITABLE BENEFICIARIES. By written notice to the
Trustee, the Corporation shall designate one or more nonprofit organizations to
be the Charitable Beneficiary of the interest in the Trust relating to such
Prohibited Transferee if (i) the shares of Class M Preferred Stock held in the
Trust would not violate the Ownership Restrictions in the hands of such
Charitable Beneficiary and (ii) each Charitable Beneficiary is an organization
described in Sections 170(b)(1)(A), 170(c)(2) and 501(c)(3) of the Code.

     11.4 NOTICE OF RESTRICTED TRANSFER. Any Person that acquires or attempts to
acquire shares of Class M Preferred Stock in violation of Section 11.1 of this
Article, or any Person that is a Prohibited Transferee such that stock is
transferred to the Trustee under Section 11.3 of this Article, shall immediately
give written notice to the Corporation of such event and shall provide to the
Corporation such other information as the Corporation may request in order to
determine the effect, if any, of such Transfer or attempted Transfer or other
event on the Corporation's status as a REIT. Failure to give such notice shall
not limit the rights and remedies of the Board of Directors provided herein in
any way.

                                       25

     11.5 OWNERS REQUIRED TO PROVIDE INFORMATION. From and after the Issue Date
certain record and Beneficial Owners and transferees of shares of Class M
Preferred Stock will be required to provide certain information as set out

          (A)  ANNUAL DISCLOSURE. Every record and Beneficial Owner of shares of
Class M Preferred Stock convertible into more than 5% (or such other percentage
between 0.5% and 5%, as provided in the applicable regulations adopted under the
Code) of the number of Outstanding shares of Equity Stock shall upon written
request by the Corporation, such request to be made within 30 days after January
1 of each year, give written notice to the Corporation stating the name and
address of such record or Beneficial Owner, the number of shares of Class M
Preferred Stock Beneficially Owned, and a full description of how such shares
are held. Each such record or Beneficial Owner of Class M Preferred Stock shall,
upon demand by the Corporation, disclose to the Corporation in writing such
additional information with respect to the Beneficial Ownership of the Class M
Preferred Stock as the Board of Directors, in its sole discretion, deems
appropriate or necessary to (i) comply with the provisions of the Code regarding
the qualification of the Corporation as a REIT under the Code and (ii) ensure
compliance with the Ownership Limit, the Initial Holder Limit or the
Look-Through Ownership Limit, as applicable. Each stockholder of record,
including without limitation any Person that holds shares of Class M Preferred
Stock on behalf of a Beneficial Owner, shall take all reasonable steps to obtain
the written notice described in this Section 11.5 from the Beneficial Owner.

          (B)  DISCLOSURE AT THE REQUEST OF THE CORPORATION. Any Person that is
a Beneficial Owner of shares of Class M Preferred Stock and any Person
(including the stockholder of record) that is holding shares of Class M
Preferred Stock for a Beneficial Owner, and any proposed transferee of shares,
shall provide such information as the Corporation, in its sole discretion, may
request in order to determine the Corporation's status as a REIT, to comply with
the requirements of any taxing authority or other governmental agency, to
determine any such compliance or to ensure compliance with the Ownership Limit,
the Initial Holder Limit and the Look-Through Ownership Limit, and shall provide
a statement or affidavit to the Corporation setting forth the number of shares
of Class M Preferred Stock already Beneficially Owned by such stockholder or
proposed transferee and any related persons specified, which statement or
affidavit shall be in the form prescribed by the Corporation for that purpose.

     11.6 REMEDIES NOT LIMITED. Nothing contained in this Article shall limit
the authority of the Board of Directors to take such other action as it deems
necessary or advisable (subject to the provisions of Section 11.12 of this
Article) (i) to protect the Corporation and the interests of its stockholders in
the preservation of the Corporation's status as a REIT and (ii) to insure
compliance with the Ownership Limit, the Initial Holder Limit and the
Look-Through Ownership Limit.

     11.7 AMBIGUITY. In the case of an ambiguity in the application of any of
the provisions of Section 11 of this Article, or in the case of an ambiguity in
any definition contained in Section 11 of this Article, the Board of Directors
shall have the power to determine the application of the provisions of this
Article with respect to any situation based on its reasonable belief,
understanding or knowledge of the circumstances.

                                       26
<PAGE>   27

     11.8 EXCEPTIONS. The following exceptions shall apply or may be established
with respect to the limitations of Section 11.1 of this Article.

          (A)  WAIVER OF OWNERSHIP LIMIT. The Board of Directors, upon receipt
of a ruling from the Internal Revenue Service or an opinion of tax counsel or
other evidence or undertaking acceptable to it, may waive the application, in
whole or in part, of the Ownership Limit to a Person subject to the Ownership
Limit, if such person is not an individual for purposes of Section 542(a) of the
Code (as modified to exclude qualified trusts from treatment as individuals
pursuant to Section 856(h)(3) of the Code) and is a corporation, partnership,
limited liability company, estate or trust. In connection with any such
exemption, the Board of Directors may require such representations and
undertakings from such Person and may impose such other conditions as the Board
of Directors deems necessary, in its sole discretion, to determine the effect,
if any, of the proposed Transfer on the Corporation's status as a REIT.

          (B)  PLEDGE BY INITIAL HOLDER. Notwithstanding any other provision of
this Article, the pledge by the Initial Holder of all or any portion of the
Class M Preferred Stock directly owned at any time or from time to time shall
not constitute a violation of Section 11.1 of this Article and the pledgee shall
not be subject to the Ownership Limit with respect to the Class M Preferred
Stock so pledged to it either as a result of the pledge or upon foreclosure.

          (C)  UNDERWRITERS. For a period of 270 days (or such longer period of
time as any underwriter described below shall hold an unsold allotment of Class
M Preferred Stock) following the purchase of Class M Preferred Stock by an
underwriter that (i) is a corporation, partnership or other legal entity and
(ii) participates in an offering of the Class M Preferred Stock, such
underwriter shall not be subject to the Ownership Limit with respect to the
Class M Preferred Stock purchased by it as a part of or in connection with such
offering and with respect to any Class M Preferred Stock purchased in connection
with market making activities.

     11.9 LEGEND. Each certificate for Class M Preferred Stock shall bear
substantially the following legend:

     "The shares of Class M Convertible Cumulative Preferred Stock represented
     by this certificate are subject to restrictions on transfer. No person may
     Beneficially Own shares of Class M Convertible Cumulative Preferred Stock
     in excess of the Ownership Restrictions, as applicable, with certain
     further restrictions and exceptions set forth in the Charter (including the
     Articles Supplementary setting forth the terms of the Class M Convertible
     Cumulative Preferred Stock). Any Person that attempts to Beneficially Own
     shares of Class M Convertible Cumulative Preferred Stock in excess of the
     applicable limitation must immediately notify the Corporation. All
     capitalized terms in this legend have the meanings ascribed to such terms
     in the

                                       27
<PAGE>   28

     Charter (including the Articles Supplementary setting forth the terms of
     the Class M Convertible Cumulative Preferred Stock), as the same may be
     amended from time to time, a copy of which, including the restrictions on
     transfer, will be sent without charge to each stockholder that so requests.
     If the restrictions on transfer are violated (i) the transfer of the shares
     of Class M Convertible Cumulative Preferred Stock represented hereby will
     be void in accordance with the Charter (including the Articles
     Supplementary setting forth the terms of the Class M Convertible Cumulative
     Preferred Stock) or (ii) the shares of Class M Convertible Cumulative
     Preferred Stock represented hereby will automatically be transferred to a
     Trustee of a Trust for the benefit of one or more Charitable
     Beneficiaries."

     11.10 SEVERABILITY. If any provision of this Article or any application of
any such provision is determined in a final and unappealable judgment to be
void, invalid or unenforceable by any Federal or state court having jurisdiction
over the issues, the validity and enforceability of the remaining provisions
shall not be affected and other applications of such provision shall be affected
only to the extent necessary to comply with the determination of such court.

     11.11 BOARD OF DIRECTORS DISCRETION. Anything in this Article to the
contrary notwithstanding, the Board of Directors shall be entitled to take or
omit to take such actions as it in its discretion shall determine to be
advisable in order that the Corporation maintain its status as and continue to
qualify as a REIT, including, but not limited to, reducing the Ownership Limit,
the Initial Holder Limit and the Look-Through Ownership Limit in the event of a
change in law.

     11.12 SETTLEMENT. Nothing in this Section 11 of this Article shall be
interpreted to preclude the settlement of any transaction entered into through

                "COMMISSION" means the Securities and Exchange Commission, or
any other federal agency at the time administering the Securities Act.

                "EXCHANGE ACT" means the Securities Exchange Act of 1934, as
amended, or any similar federal statute, and the rules and regulations of the
Commission issued under such Act, as they each may, from time to time, be in
effect.

                "REGISTRATION STATEMENT" means a registration statement filed by
the Company with the Commission for a public offering and sale of shares of
Common Stock (other than a registration statement on Form S-8 or Form S-4, or
their successors, or any other form for a similar limited purpose, or any
registration statement covering only securities proposed to be issued in
exchange for securities or assets of another corporation, or any registration
statement that does not permit secondary sales).

                "REGISTRATION EXPENSES" means the expenses described in Section
10(e) hereof.

                "REGISTRABLE STOCK" means (i) the shares of Common Stock
issuable upon exercise of this Warrant and (ii) any other shares of Common Stock
issued in respect of such shares (because of stock splits, stock dividends,
reclassifications, recapitalizations, or similar events); provided, however,
that shares of Common Stock which are shares of Registrable Stock shall cease to
be shares of Registrable Stock (A) upon any sale pursuant to a Registration
Statement, Section 4(1) of the Securities Act or Rule 144 under the Securities
Act or (B) at such time as they are eligible for sale pursuant to Rule 144(k)
under the Securities Act.

        (b)     REQUIRED REGISTRATIONS.

                (i)     At any time that the Company is eligible to file a
Registration Statement on Form S-3 (or any successor for relating to secondary
offerings), the Holder may request the Company, in writing, to effect the
registration on Form S-3 (or such successor form), of the Registrable Stock
owned by the Holder having an aggregate offering price of at least $250,000
(based on the then current Fair Market Value, determined in accordance with
Section 3(a) hereof); provided that if the underwriter (if any) managing the
offering determines that, because of marketing factors, all of the such shares
of Registrable Stock requested to be registered by the Holder and all other
holders with contractual registration rights may not be included in the
offering, then the Holder and all other holders of securities entitled by
contract to include them in such Form S-3 Registration Statement shall
participate in the registration PRO RATA based upon the number of shares of
Registrable Stock or other securities which they have requested to be so
registered (on an as-converted to shares of Common Stock basis). Thereupon, the
Company shall, as expeditiously as possible, use its best efforts to effect the
registration on Form S-3 (or such successor form) of all shares of Registrable
Stock or other securities which the Company has been requested to so register.

<PAGE>   2
                (ii)    The Company shall be required to effect up to two
registrations pursuant to Section 10(b)(i) above; provided, however, that (i) a
registration shall not count as one of the two permitted registrations if less
than one-quarter of the shares of Registrable Stock requested to be included in
such registration are included and (ii) the Company shall not be required to
effect any registration within the nine months after the effective date of any
other Registration Statement of the Company pursuant to Section 10(b)(i) or that
permits inclusion of shares of Registrable Stock pursuant to Section 10(c) of
this Warrant.

                (iii)   If at the time of any request to register shares of
Registrable Stock pursuant to this Section 10(b), the Company is engaged or has
fixed plans to engage within 90 days of the time of the request in a registered
public offering as to which the Holder may include shares of Registrable Stock
pursuant to Section 10(c), or is engaged in any other activity which, in the
good faith determination of the Company's Board of Directors, would be adversely
affected by the requested registration to the material detriment of the Company,
then the Company may at its option direct that such request be delayed for a
period not in excess of four months from the date of receipt of the request by
the Holder pursuant to this Section 10(b), such right to delay a request to be
exercised by the Company not more than once in any twelve-month period.

        (c)     INCIDENTAL REGISTRATION.

                (i)     Whenever the Company proposes to file a Registration
Statement (other than pursuant to Section 10(b)) at any time and from time to
time, it will, prior to such filing, give written notice to the Holder of its
intention to do so and, upon the written request of the Holder given within 20
days after the Company provides such notice (which request shall state the
intended method of disposition of such shares of Registrable Stock), the Company
shall use its best efforts to cause all shares of Registrable Stock which the
Company has been requested by the Holder to register to be registered under the
Securities Act to the extent necessary to permit their sale or other disposition
in accordance with the intended methods of distribution specified in the request
of the Holder; provided that the Company shall have the right to postpone or
withdraw any registration effected pursuant to this Section 10(c) without
obligation to the Holder.

                (ii)    In connection with any registration under this Section
10(c) involving an underwriting, the Company shall not be required to include
any shares of Registrable Stock in such registration unless the Holder accepts
the terms of the underwriting as agreed upon between the Company and the
underwriters selected by it pursuant to an underwriting agreement in customary
form among the Company, the Holder and the representative of such underwriters.
If in the prior written opinion of the managing underwriter it is appropriate
because of marketing factors to limit the number of shares of Common Stock to be
included in the offering, then the Company shall be required to include in the
registration only that number of shares of Registrable Stock, if any, which the
managing underwriter believes it will not jeopardize the success of the offering
by the Company. The number of shares that are entitled to be included in the
registration and underwriting shall be allocated first to the Company for
securities being sold for its own account. Thereafter, if the number of shares
of Registrable Stock and shares of Common Stock held by other holders with
contractual registration rights to be included in the offering in accordance
with the foregoing is less than the total number of shares which the

                                      -2-
<PAGE>   3

Holder and other holders with contractual registration rights have requested to
be included, then the Holder and other holders of securities by contract
entitled to include them in such registration shall participate in the
registration PRO RATA based upon their total ownership of shares of Common Stock
(giving effect to the conversion into shares of Common Stock of all securities
convertible thereunto). If any holder would thus be entitled to include more
securities than such holder requested to be registered, the excess shall be
allocated among other requesting holders PRO RATA in the manner described in the
preceding sentence.

        (d)     REGISTRATION PROCEDURES. If and whenever the Company is required
by the provisions of this Warrant to use its best efforts to effect the
registration of any of the shares of Registrable Stock under the Securities Act,
the Company shall:

                (i)     file with the Commission a Registration Statement with
respect to such shares of Registrable Stock and use its best efforts to cause
that Registration Statement to become and remain effective;

                (ii)    as expeditiously as possible prepare and file with the
Commission any amendments and supplements to the Registration Statement and the
prospectus included in the Registration Statement as may be necessary to keep
the Registration Statement as may be necessary to keep the Registration
Statement effective, in the case of a firm commitment underwritten public
offering, until each underwritten has completed the distribution of all
securities purchased by it and, in the case of any other offering, until the
earlier of the sale of all shares of Registrable Stock covered thereby or 120
days after the effective date thereof (subject to extension by the aggregate
amount of any Black Out Periods (defined in subsection 10(d)(v) below);

                (iii)   as expeditiously as possible furnish to the Holder,
counsel to the Holder and the managing underwriter such reasonable numbers of
copies of the prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents, including any
amendment of or supplement to the prospectus, as the Holder, counsel to the
Holder or the managing underwriter may reasonably request in order to facilitate
the public sale or other disposition of the shares of Registrable Stock; and

                (iv)    as expeditiously as possible use its best efforts to
register or qualify the shares of Registrable Stock covered by the Registration
Statement under the securities or Blue Sky laws of such states as the Holder
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the Holder to consummate the public sale or
other disposition in such states of the shares of Registrable Stock owned by the
Holder; provided, however, that the Company shall not be required in connection
with this paragraph (d) to qualify to do business or execute a general consent
to service of process in any jurisdiction.

                (v)     if the shares of Common Stock are covered by a Form S-3
Registration Statement, notify the Holder at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in the light of the circumstances under
which the

                                      -3-
<PAGE>   4
prospectus is used (a "Fundamental Change") and, at the request of the
Holder, promptly prepare and furnish to the Holder and each underwriter, if any,
a reasonable number of copies of a supplement to such prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such securities,
such prospectus shall not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made; PROVIDED, HOWEVER, that if the Company receives an opinion of
its counsel that the event in question constitutes a Fundamental Change and the
Company notifies the Holder that it wishes to defer disclosure of the
Fundamental Change and distribution of any related supplements to or stickers of
the prospectus and/or filing of post-effective amendments to the Registration
Statement, the Company shall be entitled to defer such disclosure, filing and/or
supplements to or stickering of the prospectus for a period of up to 60 days
and, in the case of a Fundamental Change which in the opinion of its counsel
would require a post-effective amendment to the registration statement, shall
use its best efforts to have the post-effective amendment declared effective by
the Commission as soon as practicably possible thereafter (such period of time,
a "Black Out Period"). The Holder may not sell any shares of Registrable Stock
during a Black Out Period. The Registration Statement effectiveness period set
forth in subsection 10(d)(ii) above shall be extended by the aggregate amount of
all Black Out Periods.

         If the Company has delivered preliminary or final prospectuses to the
Holder and after having done so the prospectus is amended to comply with the
requirements of the Securities Act, the Company shall promptly notify the Holder
and, if requested, the Holder shall immediately cease making offers of shares of
Registrable Stock and return all prospectuses to the Company. The Company shall
promptly provide the Holder with revised prospectuses and, following receipt of
the revised prospectuses, the Holder shall be free to resume making offers of
the shares of Registrable Stock.

        (e)     ALLOCATION OF EXPENSES. The Company will pay all Registration
Expenses of one registration under Section 10(b) of this Warrant and all
Registration Expenses of all registrations under Section 10(c) of this Warrant;
provided, however, that if a registration under Section 10(b) is withdrawn at
the request of the Holder (other than as a result of information concerning the
business or financial condition of the Company which is made known to the Holder
after the date on which such registration was requested) and if the Holder
elects not to have such registration counted as a registration requested under
Section 10(b), the Holder and such other person selling securities thereunder
shall pay the Registration Expenses of such registration PRO RATA in accordance
with the number of shares of Registrable Stock or other securities (all on an
as-converted to Common Stock basis) included in such registration. For purposes
of this Section 10(e), the term "Registration Expenses" shall mean all expenses
incurred by the Company in complying with this Section 10, including, without
limitation, all registration and filing fees, fees of the National Association
of Securities Dealers, Inc., exchange or Nasdaq National Market listing fees,
printing expenses, fees and expenses of counsel for the Company, state Blue Sky
fees and expenses, and the expense of any special audits incident to or required
by any such registration, but excluding underwriting discounts, selling
commissions and the fees and expenses of Holder's own counsel.

        (f)     INDEMNIFICATION AND CONTRIBUTION.

                                      -4-
<PAGE>   5
                (i)     In the event of any registration of any of the shares of
Registrable Stock under the Securities Act pursuant to this Warrant, the Company
will indemnify and hold harmless, to the full extent permitted by law, the
Holder, each underwriter of such shares of Registrable Stock, and each other
person, if any, who controls the Holder or such underwriter within the meaning
of the Securities Act or the Exchange Act against any losses, claims, damages or
liabilities, joint or several, to which the Holder, such underwriter or
controlling person may become subject under the Securities Act, the Exchange
Act, state securities or Blue Sky laws or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in any Registration Statement under which such shares of
Registrable Stock were registered under the Securities Act, including all
documents incorporated therein by reference, any preliminary prospectus or final
prospectus contained in the Registration Statement, or any amendment or
supplement to such Registration Statement, or arise out of or are based upon the
omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances under which they were made; and the Company will reimburse
the Holder, such underwriter and each such controlling person or any legal or
any other expenses reasonably incurred by such seller, underwriter or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that (i) the Company will
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon any untrue statement or omission
made in such Registration Statement, preliminary prospectus or final prospectus,
or any such amendment or supplement, in reliance upon and in conformity with
information furnished to the Company, in writing, by or on behalf of the Holder,
underwriter or controlling person specifically for use in the preparation
thereof and (ii) such indemnity with respect to any preliminary prospectus shall
not inure to the benefit of any seller from whom the person asserting any such
loss, claim, damage or liability purchased stock if such person did not receive
a copy of the final prospectus at or prior to the confirmation of the sale of
such stock to such person in any case where such delivery is required by the
Securities Act and the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected in the final prospectus unless such
failure to deliver the final prospectus was a result of the failure of the
Company to furnish copies of the final prospectus for delivery.

                (ii)    In the event of any registration of any of the shares of
Registrable Stock under the Securities Act pursuant to this Warrant, the Holder
will indemnify and hold harmless the Company, each of its directors and officer
and each underwriter (if any) and each person, if any, who controls the Company
or any such underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages or liabilities, joint or several, to
which the Company, such directors and officers, underwriter or controlling
person may become subject under the Securities Act, Exchange Act, state
securities or Blue Sky laws or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement under which such shares of Registrable
Stock or other securities were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement or any amendment or supplement to the Registration Statement, or arise
out of or are based upon any omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the

                                      -5-
<PAGE>   6
circumstances under which they were made, if the statement or omission was made
in reliance upon and in conformity with information relating to the Holder
furnished in writing to the Company by or on behalf of the Holder specifically
for use in connection with the preparation of such Registration Statement,
prospectus, amendment or supplement and the Holder will reimburse the Company
for any legal or any other expenses reasonably incurred by the Company in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that (i) the obligations of the Holder
hereunder shall be limited to an amount equal to the proceeds to the Holder from
the shares of Registrable Stock sold in connection with such registration, (ii)
such indemnity with respect to any preliminary prospectus shall not inure to the
benefit of the Company, if the person asserting any such loss, claim, damage or
liability did not receive a copy of the final prospectus at or prior to the
confirmation of the sale of such stock to such person in any case where such
delivery is required by the Securities Act and the untrue statement or omission
of material fact contained in the preliminary prospectus was corrected in the
final prospectus if such failure to deliver the final prospectus was a result of
the failure of the Company to furnish copies of the final prospectus for
delivery, and (iii) the Holder shall not be obligated to provide indemnity
hereunder to the extent that damages result from the failure of the Company to
promptly amend or supplement any Registration Statement or prospectus on the
basis of supplement information constitutes new facts or information relative to
the Holder and not a correction completion of statements that were inaccurate or
incomplete when originally provided by the Holder to the Company).

                (iii)   Each party entitled to indemnification under this
Section 10(f) (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided, that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (who approval shall not be
unreasonably withheld); and, provided, further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 10(f). The Indemnified
Party may participate in such defense at such party's expenses; provided,
however,, that the Indemnifying Party shall pay such expense if representation
of such Indemnified Party by the counsel retained by the Indemnifying Party and
any other party represented by such counsel in such proceeding. No Indemnifying
Party, in the defense of any such claim or litigation shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect of such claim or litigation, and no Indemnified Party
shall consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the Indemnifying Party.

                (iv)    In order to provide for just and equitable contribution
to joint liability under the Securities Act in any case in which either (i) the
Holder or any controlling person thereof, make a claim for indemnification
pursuant to this Section 10(f) but it is judicially determined (by the entry of
a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(f) provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the

                                      -6-
<PAGE>   7
part of the Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 10(f); then, in each such case,
the Company, the Holder and all other persons who have sold securities pursuant
to such Registration Statement will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others) in such proportions so the Holder is responsible for the portion
represented by the percentage that the public offering price of its shares of
Registrable Stock offered by the Registration Statement bears to the public
offering price of all securities offered by such Registration Statement, and the
Company and the other selling stockholders are responsible for the remaining
portion; provided, however, that in any such case, (A) in no event will the
Holder be required to contribute any amount in excess of the proceeds to it of
all shares of Registrable Stock sold by it pursuant to such Registration
Statement, and (B) no person or entity guilty of fraudulent misrepresentation,
within the meaning of Section 11 of the Securities Act, shall be entitled to
contribution from any person or entity who is not guilty of such fraudulent
misrepresentation.

        (g)     INDEMNIFICATION WITH RESPECT TO UNDERWRITTEN OFFERING. In the
event that shares of Registrable Stock are sold pursuant to a Registration
Statement in an underwritten offering pursuant to Section 10(b), the Company
agrees to enter into an underwriting agreement containing customary
representations and warranties with respect to the business and operations of an
issuer of the securities being registered and customary covenants and agreements
to be performed by such issuer, including without limitation customary
provisions with respect to indemnification by the Company of the underwriters of
such offering.

        (h)     INFORMATION BY HOLDER. The Holder shall furnish tot he Company
such information regarding the Holder and the distribution proposed by the
Holders as the Company may reasonably request in writing and shall be required
in connection with any registration, qualification or compliance referred to in
this Warrant.

        (i)     SURVIVAL OF TERMS. The provisions of this Section 10 shall
survive the exercise of this Warrant in whole or in party and shall inure to the
benefit of any successor Holder(s) of this Warrant by virtue of Section 9
hereof.

                                      -7-
