a share of Class R Stock (or fraction thereof) prior to the occurrence of

purposes hereof, neither the Class C Exchange, the attachment of Class R
Stock to PKS Holdings Stock upon the occurrence of the Class C Exchange nor

Restricted Period Termination Date for a given share of Class R Stock (or
fraction thereof), such share of Class R Stock (or fraction thereof) shall
separate from the share of PKS Holdings Stock to which it was attached and,
until the close of business on the Mandatory Conversion Date, shall be
freely transferable, and the Corporation or its transfer agent shall from
time to time register the transfer of the certificate representing such
share of Class R Stock (or fraction thereof) upon the books of the
Corporation, upon surrender of such certificate, duly endorsed, accompanied
by documentation reasonably satisfactory to the Corporation evidencing that
the Restricted Period Termination Date has occurred with respect to such
Class R Stock (or fraction thereof).

               3. In the event of an Attached Transfer or a Permitted
Transfer of a share of Class R Stock (or fraction thereof) following the
Class C Exchange and prior to the Restricted Period Termination Date of
such share of Class R Stock (or fraction thereof), the Corporation or its
transfer agent shall from time to time register such Attached Transfer or
Permitted Transfer of the certificate representing such share of Class R
Stock (or fraction thereof) upon the books of the Corporation, upon
surrender of such certificate, duly endorsed, accompanied by documentation
reasonably satisfactory to the Corporation evidencing the Attached Transfer
or Permitted Transfer, as the case may be, of such Class R Stock.

     D.  Optional Conversion.

          1. Subject to the provisions hereof, each share of Class R Stock
may be converted, at the option of the holder thereof (an "Optional
Conversion"), into the number of fully paid and nonassessable shares of
Class D Stock which are not Class D Stock, Non-Redeemable Series, equal to
the Conversion Ratio then in effect, and each fraction of a share of Class
R Stock may be converted into the number of fully paid and nonassessable
shares of such Class D Stock equal to such fraction multiplied by the
Conversion Ratio then in effect. No share of Class R Stock (or fraction
thereof) may be converted into Class D Stock prior to the occurrence of the
Conversion Condition with respect to such share of Class R Stock (or
fraction thereof), except as provided in paragraph K. hereof.

          2. Other than as set forth in paragraphs K. and L. hereof,
Class R Stock may not be converted into Class D Stock except as follows:

               a)     In the event that the Class D Stock is not Publicly
Traded, each share of Class R Stock (or fraction thereof) for which the
Conversion Condition has been met may be converted into Class D Stock on
any Business Day during any Private Conversion Period following the earlier
of (i) December 31, 1999, or (ii) a Change of Control; and

               b)     In the event that the Class D Stock is Publicly
Traded, each share of Class R Stock (or fraction thereof) for which the
Conversion Condition has been met may be converted into Class D Stock on
any Business Day during any Public Conversion Period after the Blackout
Period. The "Blackout Period" shall mean the 90-day period commencing on
the first day on which the Class D Stock is Publicly Traded; provided,
however, that the Board of Directors may, by resolution, extend the
Blackout Period up to 180 days from the first day on which the Class D
Stock is Publicly Traded if so requested by a managing underwriter of
Class D Stock in connection with an underwritten initial public offering
thereof. A copy of such resolution of the Board of Directors shall be made
available to any stockholder of the Corporation upon request thereby.

          3. Upon the occurrence of any Mandatory Redemption, Forced
Conversion or Mandatory Conversion of Class R Stock or any liquidation of
the Corporation, the right of Optional Conversion shall terminate at the
close of business on the full Business Day next preceding the date fixed
for such Mandatory Redemption, Forced Conversion or Mandatory Conversion or
for the payment of any amounts distributable on liquidation to the holders
of Class R Stock.

          4. The Corporation may issue fractions of shares of Class R
Stock. The Corporation shall not issue fractions of shares of Class D Stock
or scrip in lieu thereof upon conversion of Class R Stock. If any fraction
of a share of Class D Stock would, except for the provisions of this
paragraph D.4., be issuable upon conversion of any Class R Stock, the
Corporation shall in lieu thereof pay to the person entitled thereto an
amount in cash equal to the Trading Price then in effect multiplied by the
fraction represented by such fraction of a share of Class D Stock.

          5. In order to exercise the Optional Conversion privilege, the
holder of any Class R Stock to be converted shall surrender such holder's
certificate or certificates therefor to the principal office of the
transfer agent for the Class R Stock (or if no transfer agent be at the
time appointed, then the Corporation at its principal office), and shall
give written notice to the Corporation at such office that the holder
elects to convert the Class R Stock represented by such certificates, or
any number thereof. Such notice shall also state the name or names (with
address) in which the certificate or certificates for shares of Class D
Stock which shall be issuable on such conversion, and for any shares of
Class R Stock (or fractions thereof) represented by the certificate or
certificates so surrendered which are not to be converted, shall be issued,
subject to any restrictions on transfer relating to such shares of the
Class R Stock (or fractions thereof). If so required by the Corporation,
certificates surrendered for conversion shall be duly endorsed and
accompanied by documentation satisfactory to the Corporation evidencing
that the Restricted Period Termination Date has occurred with respect to
such Class R Stock.

          6. As soon as practicable after receipt during a Conversion
Period of such notice and documentation and the surrender of the
certificate or certificates for Class R Stock for which the Conversion
Condition has been met, as aforesaid, the Corporation shall cause to be
issued and delivered at such office to such holder, or on his or its
written order, a certificate or certificates for the number of full shares
of Class D Stock issuable on such conversion in accordance with the
provisions hereof, cash as provided in paragraph D.4. hereof in respect of
any fraction of a share of Class D Stock otherwise issuable upon such
conversion and a certificate or certificates for the number of shares of
Class R Stock (or fractions thereof) representing the shares of Class R
Stock (or fractions thereof) surrendered pursuant to paragraph D.5. hereof
but not so converted. Such shares of Class D Stock, when issued, shall be
fully paid and nonassessable and free from all taxes, liens, charges and
security interests created by or imposed upon the Corporation with respect
to the issuance and holding thereof.

          7. The Corporation shall at all times when the Class R Stock
shall be outstanding reserve and keep available out of its authorized but
unissued Class D Stock, for the purposes of effecting the conversion of the
Class R Stock, such number of its duly authorized shares of Class D Stock
as shall from time to time be sufficient to effect the conversion of all
outstanding Class R Stock. Before taking any action which would cause an
adjustment reducing the Conversion Value below the then par value of the
shares of Class D Stock issuable upon conversion of the Class R 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 nonassessable shares of such Class D Stock at
such adjusted Conversion Value.

          8. All shares of Class R Stock (and fractions thereof) which
shall have been surrendered for conversion as herein provided shall no
longer be deemed to be outstanding and all rights with respect to such
shares, including the rights, if any, to receive notices and to vote, shall
forthwith cease and terminate except only the right of the holder thereof
to receive shares of Class D Stock and cash for fractional shares of Class
D Stock in exchange therefor and payment of any accrued and unpaid
dividends thereon. Any shares of Class R Stock (and fractions thereof) so
converted shall be retired and canceled and shall not be reissued, and the
Corporation shall from time to time take such appropriate action as may be
necessary to reduce the authorized Class R Stock accordingly.

to Provide Conversion Ratio Certificates and Appraisals.

however, that prior to the delivery of the first Conversion Ratio
Certificate, the Conversion Value shall be the Fixed Conversion Value, the

Value divided by (ii) the Trading Price.

beginning with the end of the fiscal year ending in 1999, the Class D Stock
is not Publicly Traded, the Corporation shall, no earlier than 20 days nor
later than 60 days following the end of such fiscal year, cause to be
provided to each office designated for conversion of Class R Stock, a copy
of a certificate (the "Private Conversion Ratio Certificate") signed by two
officers of the Corporation setting forth the Conversion Ratio, Conversion
Value and Trading Price as of the end of such fiscal year, calculated in
each case pursuant to this paragraph E. In addition, if a Change of Control
occurs when the Class D Stock is not Publicly Traded, the Corporation shall
within 60 days following such Change of Control, cause to be provided to
each office designated for conversion of Class R Stock, such a Private
Conversion Ratio Certificate.

          The "Trading Price" set forth in such Private Conversion Ratio
Certificate shall be the Appraised Value set forth in the most recent
Appraisal delivered to the Corporation and approved by the Board of
Directors.

          If, at the end of any fiscal year of the Corporation, beginning
with the end of the fiscal year ending in 1999, the Class D Stock is not
Publicly Traded, the Corporation shall cause to be prepared and delivered
to the Board of Directors and approved by the Board of Directors, prior to
60 days following the end of such fiscal year, an appraisal (an
"Appraisal") of the per share value of the Class D Stock as of the last day
of such fiscal year by an Investment Bank. If a Change of Control occurs or
the Board of Directors should determine to cause a Forced Conversion, and
the Class D Stock is not Publicly Traded, the Corporation shall cause to be
prepared and delivered to the Board of Directors and approved by the Board
of Directors, within 60 days following such Change of Control or
determination of the Board of Directors, an Appraisal of the per share
value of the Class D Stock as of the date of such Change of Control or
determination of the Board of Directors. Such Investment Bank shall
determine the per share value of the Class D Stock as if the Class D Stock
was Publicly Traded and shall submit such per share value to the Board of
Directors for its approval. The value per share of the Class D Stock as
approved by the Board of Directors shall be the "Appraised Value." In
determining the Appraised Value, the Investment Bank shall place
substantial, but not exclusive, emphasis on valuations of comparable
companies in the public equity markets, and shall not take into account
factors such as control premiums, minority discounts or illiquidity
discounts that would not generally apply to such companies.

          As promptly as practicable following its delivery of any Private
Conversion Ratio Certificate, the Corporation shall cause to be given to
each of the registered holders of Class R Stock at such holder's address
appearing upon the books of the Corporation a copy of such Private
Conversion Ratio Certificate by first class mail, postage prepaid.

          4. During any period in which the Class D Stock is Publicly
Traded, the Corporation shall, on the last Business Day of each calendar
month, cause to be provided to each office designated for conversion of
Class R Stock, a copy of a certificate (the "Public Conversion Ratio
Certificate"), signed by two officers of the Corporation, setting forth the
Conversion Ratio, Conversion Value and Trading Price as of the close of
business on such Business Day, calculated in each case pursuant to this
paragraph E.

          The "Trading Price" set forth in such Public Conversion Ratio
Certificate shall be equal to the Current Trading Value of one share of
Class D Stock as of the close of business on the last Business Day of such
calendar month. Notwithstanding anything herein to the contrary, if, during
any period being used to calculate such Current Trading Value (the
"Calculation Period"), any event has occurred to cause the Conversion Ratio
and/or the Conversion Value to be adjusted pursuant to paragraph F. hereof
(an "Adjustment Event"), the Corporation shall in good faith determine such
Conversion Ratio and/or the Conversion Value, as appropriate, so as to give
pro forma effect to the Adjustment Event immediately prior to the
Calculation Period.

          The Corporation shall provide any holder of Class R Stock with a
copy of any Public Conversion Ratio Certificate upon request. Beginning on
the day on which the first Public Conversion Ratio Certificate is provided
pursuant to this paragraph E.4., the Corporation shall maintain a
reasonable means to allow holders to be informed of the value of the
Conversion Ratio as set forth in the most recent Public Conversion Ratio
Certificate on an immediate basis during business hours on each Business
Day on which Class R Stock is issued and outstanding.

          5. All calculations and determinations required to be made by the
Corporation pursuant hereto shall be made by the Corporation in good faith.
All such calculations and determinations shall be conclusive unless
otherwise specifically provided hereby.

          6. Conversion Ratio Certificates may, at the Corporation's
discretion, be prepared by an agent of the Corporation. In such case each
such Conversion Ratio Certificate shall be signed by an authorized
signatory of such agent and countersigned by two officers of the
Corporation.

          7. Upon any conversion of Class R Stock into Class D Stock, in no
event shall any such Class R Stock be converted into Class D Stock,
Non-Redeemable Series.

     F.  Anti-dilution Provisions.

          1. If the Corporation shall (a) pay a dividend on any of its
shares of capital stock (including Class D Stock) in shares of Class D
Stock, (b) subdivide its outstanding shares of Class D Stock, (c) combine
its outstanding shares of Class D Stock into a smaller number of shares of
Class D Stock or (d) in an event or manner other than as set forth in
paragraph F.4. below, issue any shares of its capital stock in a
reclassification of the Class D Stock (each, a "Conversion Term Adjustment
Event"):

               a)     Each of the Fixed Terms shall be adjusted to the
value determined by multiplying (x) the Fixed Term immediately prior to
such Conversion Term Adjustment Event, by (y) a fraction, the numerator of
which is the number of shares of Class D Stock outstanding immediately
prior to such Conversion Term Adjustment Event, and the denominator of
which is the number of shares of Class D Stock outstanding immediately
after such Conversion Term Adjustment Event; and

               b)     Each of the Inverse Fixed Terms shall be adjusted to
the value determined by multiplying (x) such Inverse Fixed Term immediately
prior to such Conversion Term Adjustment Event, by (y) a fraction, the
numerator of which is the number of shares of Class D Stock outstanding
immediately after such Conversion Term Adjustment Event, and the
denominator of which is the number of shares of Class D Stock outstanding
immediately prior to such Conversion Term Adjustment Event.

          2. If the Corporation shall issue Convertible Securities to all
holders of its outstanding Class D Stock (other than pursuant to any rights
agreement in connection with a stockholder rights plan approved by the
Board of Directors), without payment of additional consideration by such
holders, entitling them (for a period expiring within 45 days after the
record date mentioned below) to subscribe for or purchase shares of Class D
Stock at a price per share that is lower than the Trading Price as set
forth in the most recent Conversion Ratio Certificate prior to the record
date mentioned below (or, if no Conversion Ratio Certificate has yet been
provided, equal to the Base Price immediately prior to such record date) (a
"Discounted Stock Adjustment Event"):

               a)     Each of the Fixed Terms shall be adjusted to the
value determined by multiplying (x) such term immediately prior to such
Discounted Stock Adjustment Event, by (y) a fraction, (i) the numerator of
which shall be the number of shares of Class D Stock outstanding on the
date of such Discounted Stock Adjustment Event plus the number of shares
which the aggregate offering price of the total number of shares of Class D
Stock so offered would purchase at the price per share of Class D Stock
equal to the Trading Price as set forth in the most recent Conversion Ratio
Certificate prior to the record date mentioned below (or, if no Conversion
Ratio Certificate has yet been provided, equal to the Base Price
immediately prior to such record date), and (ii) the denominator of which
shall be the number of shares of Class D Stock outstanding on the date of
such Discounted Stock Adjustment Event plus the number of additional shares
of Class D Stock offered for subscription or purchase.

               b)     Each of the Inverse Fixed Terms shall be adjusted to
the value determined by multiplying (x) such term immediately prior to such
Discounted Stock Adjustment Event, by (y) a fraction, (i) the numerator of
which shall be the number of shares of Class D Stock outstanding on the
date of such Discounted Stock Adjustment Event plus the number of
additional shares of Class D Stock offered for subscription or purchase,
and (ii) the denominator of which shall be the number of shares of Class D
Stock outstanding on the date of such Discounted Stock Adjustment Event
plus the number of shares which the aggregate offering price of the total
number of shares of Class D Stock so offered would purchase at the price
per share of Class D Stock equal to the Trading Price as set forth in the
most recent Conversion Ratio Certificate prior to the record date mentioned
below (or, if no Conversion Ratio Certificate has yet been provided, equal
to the Base Price immediately prior to such record date).

Such adjustment shall be made whenever such Convertible Securities are
issued, and shall become effective immediately on the date of issuance
retroactive to the record date for the determination of stockholders
entitled to receive such Convertible Securities.

          3. If the Corporation shall pay any Regular Dividend or
Extraordinary Dividend (a "Dividend Adjustment Event"):

               a)     Each of the Fixed Terms shall be adjusted to such
value determined by multiplying (x) such term immediately prior to such
Dividend Adjustment Event, by (y) a fraction, (i) the numerator of which
shall be the Trading Price immediately prior to such Dividend Adjustment
Event minus the per share amount received by holders of Class D Stock in
connection with such dividend, and (ii) the denominator of which shall be
the Trading Price immediately prior to such Dividend Adjustment Event.

               b)     Each of the Inverse Fixed Terms shall be adjusted to
such value determined by multiplying (x) such term immediately prior to
such Dividend Adjustment Event, by (y) a fraction, (i) the numerator of
which shall be the Trading Price immediately prior to such Dividend
Adjustment Event, and (ii) the denominator of which shall be the Trading
Price immediately prior to such Dividend Adjustment Event minus the per
share amount received by holders of Class R Stock in connection with such
dividend.

     Any non-cash portions of an Extraordinary Dividend set forth in this
paragraph F.3. shall be based upon the fair market value of such non-cash
portion at the time such Extraordinary Dividend is declared or paid, as
determined in good faith by the Board of Directors.

          4. If any capital reorganization or reclassification of the
capital stock of the Corporation, or consolidation or merger of the
Corporation with another corporation, or share exchange involving the
outstanding shares of the Corporation's capital stock or the sale of all or
substantially all of its assets to another corporation shall be effected in
such a way that holders of Class D Stock shall be entitled to receive
stock, securities, cash or other property with respect to or in exchange
for Class D Stock, then, as a condition of such reorganization,
reclassification, consolidation, merger, share exchange or sale, lawful and
adequate provision shall be made whereby the holders of the Class R Stock
shall have the right to acquire and receive upon conversion of the Class R
Stock (after and subject to the rights of holders of Preferred Stock, if
any), such shares of stock, securities, cash or other property issuable or
payable (as part of the reorganization, reclassification, consolidation,
merger, share exchange or sale) with respect to or in exchange for such
number of outstanding shares of Class D Stock as would have been received
upon conversion of the Class R Stock at the Conversion Ratio immediately
prior to such event. The Corporation shall not effect any such
consolidation, merger or sale, unless prior to the consummation thereof the
successor corporation (if other than the Corporation) resulting from such
consolidation or merger or the corporation purchasing such assets shall
assume by written instrument mailed or delivered to the holders of the
Class R Stock at the last address of each such holder appearing on the
books of the Corporation, the obligation to deliver to each such holder
such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such holder may be entitled to receive upon
conversion of such holder's shares of Class R Stock.

          5. The Corporation shall not effect a reclassification of the
Class R Stock without the approval of holders of a majority of the shares
of Class R Stock.

          6. The provisions of this paragraph F. shall not apply to any
Class D Stock issued, issuable or deemed outstanding pursuant hereto: (a)
to any person pursuant to any stock option, stock purchase or similar plan
or arrangement for the benefit of employees of the Corporation or its
subsidiaries in effect on the Initial Issuance Date or thereafter adopted
by the Board of Directors of the Corporation; (b) pursuant to options,
warrants and conversion rights in existence on the Initial Issuance Date;
or (c) on conversion of the Class R Stock.

          7. In the event of:

               a)     the occurrence of any event causing the adjustment of
the Fixed Term or any Inverse Fixed Term pursuant to paragraphs F.1., F.2.
or F.3. hereof; or

               b)     there shall be any capital reorganization or
reclassification of the capital stock of the Corporation, including any
subdivision or combination of its outstanding shares of Class D Stock, or
consolidation or merger of the Corporation with, or sale of all or
substantially all of its assets to, another corporation; or

               c)     there shall be a voluntary or involuntary
dissolution, liquidation or winding up of the Corporation; or

               d)     the occurrence of a Change of Control;

     then, in connection with such event, the Corporation shall give to the
holders of the Class R Stock:

               (1)     in the case of a), b) or c) above, at least twenty
(20) days prior written notice of the date on which the books of the
Corporation shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in
respect of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding up, provided that if the
Class R Stock is Publicly Traded, such notice must be given prior to the
end of the Public Conversion Period prior to such record date;

               (2)     in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, at least twenty (20) days prior written notice of the date when
the same shall take place. Such notice in accordance with the foregoing
clause shall also specify, in the case of any such dividend, distribution
or subscription rights, the date on which the holders of Class D Stock
shall be entitled thereto, and shall also specify the date on which the
holders of Class D Stock shall be entitled to exchange their Class D Stock
for securities or other property deliverable upon such reorganization,
reclassification consolidation, merger, sale, dissolution, liquidation or
winding up, as the case may be; and

               (3)     in the case of d) above, five days after such Change
of Control, unless notice is required sooner by (1) above; provided that if
stockholder approval is required to effect such Change of Control, notice
shall be provided concurrently with the notice to stockholders in
connection with obtaining such stockholder approval.

Each such written notice shall be given by first class mail, postage
prepaid, addressed to the holders of the Class R Stock at the address of
each such holder as shown on the books of the Corporation.

8. If any event occurs as to which, in the opinion of the Board of
Directors of the Corporation, the provisions of this paragraph F. are not
strictly applicable or if strictly applicable would not fairly protect the
rights of the holders of the Class R Stock in accordance with the essential
intent and principles of such provisions, then the Board of Directors shall
make an adjustment in the application of such provisions, in accordance
with such essential intent and principles, so as to protect such rights as
aforesaid. Upon the occurrence of any such adjustment pursuant to this
paragraph F.8., the Corporation shall give notice to the holders of Class R
Stock as provided in paragraph F.7(1), F.7(2) or F.7(3) hereof, as
appropriate. All calculations and determinations required to be made by the
Corporation pursuant hereto shall be made by the Corporation in good faith.
All such calculations and determinations shall be conclusive unless
otherwise specifically provided hereby.

G.      Rank.

After the Class C Exchange, the Class R Stock shall, with respect to
dividend distributions and with respect to distributions of assets and
rights upon the liquidation, winding up and dissolution of the Corporation,
rank on a parity with Class D Stock and junior to Preferred Stock.

H.      Dividends.

1. Prior to the Class C Exchange, no dividends may be declared or paid with
respect to Class R Stock. After (i) the Class C Exchange and (ii) dividends
payable on any Preferred Stock have been declared and set aside on any such
Preferred Stock having a preference over the Class D Stock and Class R
Stock with respect to the payment of such dividends, holders of Class R
Stock shall only be entitled to receive dividends, out of any assets or
funds legally available therefor, in an amount per share of Class R Stock
(and proportionally to such amount for fractional shares thereof) as set
forth below:

a)     If and when a Regular Dividend is declared, an amount which is equal
to (i) the Conversion Ratio then in effect multiplied by (ii) the aggregate
per share amount of such Regular Dividend declared on a share of Class D
Stock; and

b)     Subject to paragraph K. hereof, if and when an Extraordinary
Dividend is declared, an amount which is equal to (i) the Conversion Ratio
then in effect multiplied by (ii) one-fourth of the sum of (A) the
aggregate per share amount of all cash portions of such Extraordinary
Dividend plus (B) the aggregate per share amount (based upon the fair
market value of the non-cash portion of such Extraordinary Dividend at the
time such Extraordinary Dividend is declared or paid as determined in good
faith by the Board of Directors) of all non-cash portions of such
Extraordinary Dividend, in each case as declared on a share of Class D
Stock.

Such dividends shall be declared and paid contemporaneously with the
declaration and payment of the related dividend on the Class D Stock; and
the foregoing are the only times when dividends shall be declared and paid
with respect to the Class R Stock.

2. All dividends paid with respect to shares of Class R Stock pursuant to
this paragraph H. shall be paid pro rata and in like manner to all of the
holders entitled thereto.

3. No Regular or Extraordinary Dividends shall be declared by the Board of
Directors or paid or set apart for payment by the Corporation on Class D
Stock unless, contemporaneously therewith, a like ratable dividend
calculated in accordance with this paragraph H. is declared and paid, or
declared and a sum set apart sufficient for such payment, on the Class R
Stock, payable as set forth herein.

I.      Liquidation Rights.

1. Prior to the Class C Exchange, in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation
("Liquidation"), the holders of Class R Stock then outstanding shall not be
entitled to receive any property, assets or funds of the Corporation.

2. In the event of a Liquidation following the Class C Exchange, holders of
Class R Stock then outstanding shall be entitled to be paid ratably out of
the assets and funds of the Corporation legally available for distribution
to its stockholders, after and subject to the payment in full of all
amounts required to be distributed to the holders of any Preferred Stock
upon such Liquidation, an amount equal to (a) the Liquidation Ratio then in
effect multiplied by (b) the aggregate amount of all assets and funds
remaining available for distribution to holders of Class D Stock and
Class R Stock.

J.   Voting.

     1. Prior to the Class C Exchange, except as required by law, holders
of Class R Stock shall not be entitled to vote on any matter.

     2. After the Class C Exchange, each issued and outstanding share of
Class R Stock (and fraction thereof) shall be entitled to vote only (i) for
the election of directors, and (ii) as required by law. On matters on which
the holders of Class R Stock are entitled to vote, (a) each issued and
outstanding share of Class R Stock shall be entitled to the number of votes
equal to the Conversion Ratio as of the record date for determination of
stockholders entitled to vote on such matter, and (b) each issued and
outstanding fraction of a share of Class R Stock shall be entitled to (x)
such fraction, multiplied by (y) the number of votes equal to the
Conversion Ratio as of the record date for determination of stockholders
entitled to vote on such matter. Except as required by law, holders of
Class R Stock shall vote together with the holders of Class D Stock as a
single class on all matters on which holders of Class R Stock are entitled
to vote.

K.   Forced Conversion.

     1. In the event that the Board of Directors determines that the
Corporation should convert all issued and outstanding shares of Class R
Stock (and fractions thereof) into Class D Stock, the Corporation may at
its option, elect to cause all, but not less than all, shares of Class R
Stock (and fractions thereof) to be converted (a "Forced Conversion") into
Class D Stock at the Conversion Ratio (i) in the event that the Class D
Stock is not Publicly Traded, set forth in the Private Conversion Ratio
Certificate delivered pursuant to paragraph E.3. hereof as a result of such
determination by the Board of Directors, and (ii) in the event that the
Class D Stock is Publicly Traded, in effect on the date the Board of
Directors determines to cause such a conversion; provided, however, that if
such Conversion Ratio in effect was calculated using a Conversion Value of
less than $25.00, such Conversion Ratio shall be recalculated using a
Conversion Value of $25.00.

     2. All holders of record of shares of Class R Stock (or fractions
thereof) will be given at least ten (10) days prior written notice of the
date fixed and the place designated for such conversion of Class R Stock
pursuant to this paragraph K. Such notice shall be sent by mail, first
class, postage prepaid, to each record holder of shares of Class R Stock
(or fractions thereof) at such holder's address appearing on the stock
register. On or before the date fixed for conversion each holder of shares
of Class R Stock (or fractions thereof) shall surrender his or its
certificate or certificates for all such shares to the Corporation at the
place designated in such notice, and shall thereafter receive certificates
for the number of shares of Class D Stock and cash in lieu of any
fractional share of Class D Stock to which such holder is entitled pursuant
to this paragraph K. On the date fixed for conversion, all rights with
respect to the Class R Stock so converted will terminate, except only the
rights of the holders thereof, upon surrender of their certificate or
certificates therefor, to receive certificates for the number of shares of
Class D Stock into which such Class R Stock has been converted, cash as
provided in paragraph D.4. hereof in respect of any fraction of a share of
Class D Stock otherwise issuable upon such conversion and payment of any
accrued and unpaid dividends thereon. If so required by the Corporation,
certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the
Corporation, duly executed by the registered holder or by his attorneys
duly authorized in writing. All certificates evidencing shares of Class R
Stock (or fractions thereof) which are required to be surrendered for
conversion in accordance with the provisions hereof shall, from and after
the date fixed for conversion, be deemed to have been retired and canceled
and the shares of Class R Stock (or fractions thereof) represented thereby
converted into Class D Stock for all purposes, notwithstanding the failure
of the holder or holders thereof to surrender such certificates on or prior
to such date. As soon as practicable after the date of such conversion and
the surrender of the certificate or certificates for Class R Stock as
aforesaid, the Corporation shall cause to be issued and delivered to such
holder, or on such holder's written order, a certificate or certificates
for the number of full shares of Class D Stock issuable on such conversion
in accordance with the provisions hereof, cash as provided in paragraph
D.4. hereof in respect of any fraction of a share of Class D Stock
otherwise issuable upon such conversion and payment of any accrued and
unpaid dividends thereon.

L.   Mandatory Conversion.

     1. Each share of Class R Stock (and fraction thereof) outstanding as
of the Mandatory Conversion Date shall, automatically, and without further
action by or on behalf of the Corporation, the Corporation's transfer agent
or the holder of such share of Class R Stock, be converted (the "Mandatory
Conversion") into shares of Class D Stock (and cash in lieu of any
fractions of shares of Class D Stock as provided in paragraph D.4. hereof)
at the Conversion Ratio in effect as of such Mandatory Conversion Date.

     2. All holders of record of shares of Class R Stock (or fractions
thereof) will be given written notice at least ten (10) days prior to the
Mandatory Conversion Date stating the place designated for mandatory
conversion of all of such shares of Class R Stock pursuant to this
paragraph L. Such notice shall be sent by mail, first class, postage
prepaid, to each record holder of shares of Class R Stock (or fractions
thereof) at such holder's address appearing on the stock register. On or
before the Mandatory Conversion Date, each holder of Class R Stock shall
surrender his or its certificate or certificates for all such shares (or
fractions thereof) to the Corporation at the place designated in such
notice, and shall thereafter receive certificates for the number of shares
of Class D Stock and cash in lieu of any fractional shares of Class D Stock
to which such holder is entitled pursuant to this paragraph L. On the date
fixed for conversion, all rights with respect to the Class R Stock so
converted will terminate, except only the rights of the holders thereof,
upon surrender of their certificate or certificates therefor, to receive
certificates for the number of shares of Class D Stock into which such
Class R Stock has been converted, cash as provided in paragraph D.4. hereof
in respect of any fraction of a share of Class D Stock otherwise issuable
upon such conversion and payment of any accrued and unpaid dividends
thereon. If so required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by written instrument or
instruments of transfer, in form satisfactory to the Corporation, duly
executed by the registered holder or by his attorneys duly authorized in
writing. All certificates evidencing shares of Class R Stock (or fractions
thereof) which are required to be surrendered for conversion in accordance
with the provisions hereof shall, from and after the date fixed for
conversion, be deemed to have been retired and canceled and the shares of
Class R Stock (and fractions thereof) represented thereby converted into
Class D Stock for all purposes, notwithstanding the failure of the holder
or holders thereof to surrender such certificates on or prior to such date.
As soon as practicable after the date of such Mandatory Conversion and the
surrender of the certificate or certificates for Class R Stock as
aforesaid, the Corporation shall cause to be issued and delivered to such
holder, or on such holder's written order, a certificate or certificates
for the number of full shares of Class D Stock issuable on such conversion
in accordance with the provisions hereof, cash as provided in paragraph
D.4. hereof in respect of any fraction of a share of Class D Stock
otherwise issuable upon such conversion and payment of any accrued and
unpaid dividends thereon.

     M.  Mandatory Redemption.  If the Class C Exchange (i) is abandoned by
the Board of Directors prior to the Class C Exchange, or (ii) has not
occurred by the close of business on the Mandatory Redemption Date, the
Corporation shall redeem (to the extent funds are legally available
therefor), all shares of Class R Stock (and fractions thereof) then
outstanding for a per share price equal to the par value thereof) (such
amount is hereinafter referred to as the "Redemption Price"). Such
Redemption Price shall be paid to each record holder of Class R Stock as of
the Mandatory Redemption Date, promptly after such date, by certified or
bank cashier's check, sent by mail, first class, postage prepaid, to each
record holder of shares of Class R Stock at such holder's address appearing
on the stock register. If the Corporation is unable at such date to redeem
all shares of Class R Stock (and fractions thereof) because funds are not
legally available therefor, then the Corporation shall redeem such shares
as soon thereafter as funds are legally available for redemption of such
shares.

     N.  Taxes.  The Corporation shall pay all documentary stamp taxes
attributable to the initial issuance of Class R Stock and of the shares of
Class D Stock issuable upon conversion of Class R Stock; provided that the
Corporation shall not be required to pay any tax or taxes which may be
payable in respect of any transfer involved in the issue of any
certificates representing shares of Class R Stock (or fractions thereof) or
Class D Stock in a name other than the holder of the certificate or
certificates surrendered upon conversion of Class R Stock, and the
Corporation shall not be required to issue or deliver such certificates
unless or until the person or persons requesting the issuance thereof shall
have paid to the Corporation the amount of such tax or shall have
established to the satisfaction of the Corporation that such tax has been
paid.
