Preferred Shares shall have the right by giving written notice to the Company to
designate a member of the Board of Directors of the Corporation (the "Series C

conversion of such holder's Preferred Shares as of the date of such Organic
Change (without taking into account any limitations or restrictions on the
convertibility of the Preferred Shares).

          8.   Conversion.

               (a)  Holder's Conversion Right. Subject to the provisions of
Section 11, at any time or times on or after the Issuance Date, any holder of
Preferred Shares shall be entitled to convert any whole or fractional number of
Preferred Shares into fully paid and nonassessable shares of Common Stock in
accordance with Section 8(c) at the Conversion Rate. The Corporation shall not
issue any fraction of a share of Common Stock upon any conversion. All shares of
Common Stock (including fractions thereof) issuable upon conversion of more than
one Preferred Share by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of a fraction of
a share of Common Stock. If, after the aforementioned aggregation, the issuance
would result in the issuance of a fraction of a share of Common Stock, the
Corporation shall round such fraction of a share of Common Stock up or down to
the nearest whole share with one half shares being rounded up.

               (b)  Conversion Rate. The number of shares of Common Stock
issuable upon conversion of each Preferred Share pursuant to Section 8(a) shall
be determined according to the following formula (the "Conversion Rate"):

                                Conversion Amount
                                Conversion Price

               (c)  Mechanics of Conversion. The conversion of Preferred Shares
shall be conducted in the following manner:

                    (i)  Holder's Delivery Requirements. To convert Preferred
Shares into shares of Common Stock on any date (the "Conversion Date"), the
holder thereof shall (A) transmit by facsimile (or otherwise deliver) a copy of
a properly completed notice of conversion executed by the registered holder of
the Preferred Shares subject to such conversion in the form attached hereto as
Exhibit I (the "Conversion Notice") to the Corporation and the Corporation's
designated transfer agent for the Common Stock (the "Transfer Agent") and (B) if
required by Section 8(c)(vii), surrender to a common carrier for delivery to the
Corporation as soon as practicable following such date the original certificates
representing the Preferred Shares being converted (or compliance with the
procedures set forth in Section 12) (the "Preferred Stock Certificates").

                    (ii) Corporation's Response. Upon receipt by the
Corporation of copy of a Conversion Notice, the Corporation shall (A) as soon as
practicable, but in any event within two (2) Business Days, send, via facsimile,
a confirmation of receipt of such Conversion Notice to such holder and the
Transfer Agent, which confirmation shall constitute an instruction to the
Transfer Agent to process such Conversion Notice in accordance with the terms
herein and (B) on or before the second (2/nd/) Business Day following the date
of receipt by the

                                       18



Corporation of such Conversion Notice (the "Share Delivery Date"), (1) issue and
deliver to the address as specified in the Conversion Notice, a certificate,
registered in the name of the holder or its designee, for the number of shares
of Common Stock to which the holder shall be entitled, or (2) provided the
Transfer Agent is participating in The Depository Trust Corporation ("DTC") Fast
Automated Securities Transfer Program, upon the request of the holder, credit
such aggregate number of shares of Common Stock to which the holder shall be
entitled to the holder's or its designee's balance account with DTC through its
Deposit Withdrawal Agent Commission system. If the number of Preferred Shares
represented by the Preferred Stock Certificate(s) submitted for conversion is
greater than the number of Preferred Shares being converted, then the
Corporation shall, as soon as practicable and in no event later than five
Business Days after receipt of the Preferred Stock Certificate(s) (the
"Preferred Stock Delivery Date") and at its own expense, issue and deliver to
the holder a new Preferred Stock Certificate representing the number of
Preferred Shares not converted.

                     (iii) Dispute Resolution. In the case of a dispute as to
the determination of the Conversion Price or the arithmetic calculation of the
Conversion Rate, the Corporation shall instruct the Transfer Agent to issue to
the holder the number of shares of Common Stock that is not disputed and shall
transmit an explanation of the disputed determinations or arithmetic
calculations to the holder via facsimile within five (5) Business Days of
receipt of such holder's Conversion Notice or other date of determination. If
such holder and the Corporation are unable to agree upon the determination of
the Conversion Price or arithmetic calculation of the Conversion Rate within
five (5) Business Days of such disputed determination or arithmetic calculation
being transmitted to the holder, then the Corporation shall within three (3)
Business Days submit via facsimile (a) the disputed determination of the
Conversion Price to an independent, reputable investment bank selected by the
Corporation and approved by the holders of at least 51% of the Preferred Shares
then outstanding or (b) the disputed arithmetic calculation of the Conversion
Rate to an independent, outside accountant approved by the holders of at least
51% of the Preferred Shares then outstanding. The Corporation shall cause the
investment bank or the accountant, as the case may be, to perform the
determinations or calculations and notify the Corporation and the holders of the
results no later than five (5) Business Days from the time it receives the
disputed determinations or calculations. Such investment bank's or accountant's
determination or calculation, as the case may be, shall be binding upon all
parties absent manifest error.

                     (iv)  Record Holder. The Person or Persons entitled to
receive the shares of Common Stock issuable upon a conversion of Preferred
Shares shall be treated for all purposes as the record holder or holders of such
shares of Common Stock on the Conversion Date.

                     (v)   Pro Rata Conversion. In the event the Corporation
receives a Conversion Notice from more than one holder of Preferred Shares for
the same Conversion Date and the Corporation can convert some, but not all, of
such Preferred Shares by virtue of the limitations expressly set forth in
Section 11 hereof, the Corporation shall convert from each holder of Preferred
Shares electing to have Preferred Shares converted at such time a pro rata
amount of such holder's Preferred Shares submitted for conversion based on the
number of Preferred Shares submitted for conversion on such date by such holder
relative to the number of Preferred Shares submitted for conversion on such
date.

                                       19



                    (vi) Book-Entry. Notwithstanding anything to the contrary
set forth herein, upon conversion of Preferred Shares in accordance with the
terms hereof, the holder thereof shall not be required to physically surrender
the certificate representing the Preferred Shares to the Corporation unless the
full or remaining number of Preferred Shares represented by the certificate are
being converted. The holder and the Corporation shall maintain records showing
the number of Preferred Shares so converted and the dates of such conversions or
shall use such other method, reasonably satisfactory to the holder and the
Corporation, so as not to require physical surrender of the certificate
representing the Preferred Shares upon each such conversion. In the event of any
dispute or discrepancy, such records of the Corporation establishing the number
of Preferred Shares to which the record holder is entitled shall be controlling
and determinative in the absence of manifest error. Notwithstanding the
foregoing, if Preferred Shares represented by a certificate are converted as
aforesaid, the holder may not transfer the certificate representing the
Preferred Shares unless the holder first physically surrenders the certificate
representing the Preferred Shares to the Corporation, whereupon the Corporation
will forthwith issue and deliver upon the order of the holder a new certificate
of like tenor, registered as the holder may request, representing in the
aggregate the remaining number of Preferred Shares represented by such
certificate. The holder and any assignee, by acceptance of a certificate,
acknowledge and agree that, by reason of the provisions of this paragraph,
following conversion of any Preferred Shares, the number of Preferred Shares
represented by such certificate may be less than the number of Preferred Shares
stated on the face thereof. Each certificate for Preferred Shares shall bear the
following legend:

               ANY TRANSFEREE OF THIS CERTIFICATE SHOULD CAREFULLY REVIEW THE
               TERMS OF THE COMPANY'S CERTIFICATE OF VOTE OF DIRECTORS
               ESTABLISHING A SERIES OF A CLASS OF STOCK RELATING TO THE
               PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE, INCLUDING
               SECTION 8(c)(vi) THEREOF. THE NUMBER OF PREFERRED SHARES
               REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF
               PREFERRED SHARES STATED ON THE FACE HEREOF PURSUANT TO SECTION
               8(c)(vi) OF THE CERTIFICATE OF VOTE RELATING TO THE PREFERRED
               SHARES REPRESENTED BY THIS CERTIFICATE.

               (d)  Taxes. The Corporation shall pay any and all documentary,
stamp, transfer (but only in respect of the registered holder thereof) and other
similar taxes that may be payable with respect to the issuance and delivery of
Common Stock upon the conversion of Preferred Shares.

               (e)  Adjustments to Conversion Price. The Conversion Price shall
be subject to adjustment from time to time as provided in this Section 8(e).

                    (i)   Adjustment of Conversion Price upon Issuance of Common
Stock. If and whenever on or after the Issuance Date, the Corporation issues or
sells, or in accordance with this Section 8(e) is deemed to have issued or sold,
any shares of Common Stock (including the issuance or sale of shares of Common
Stock owned or held by or for the account

                                       20



of the Corporation, but excluding shares of Common Stock: (a) issued or deemed
to have been issued by the Corporation in connection with an Approved Stock Plan
(not to exceed 2,500,000 shares of Common Stock as constituted on the date
hereof and provided in each case that the exercise or purchase price for any
such share shall not be less than 85% of the fair market value (determined in
good faith by the Corporation's Board of Directors) of the Common Stock on the
date of the grant); (b) deemed to have been issued upon issuance of the
Preferred Shares or issued upon conversion of the Preferred Shares and (c)
issued upon exercise of Options or Convertible Securities which are outstanding
on the date immediately preceding the Issuance Date, provided that such issuance
of shares of Common Stock upon exercise of such Options or Convertible
Securities is made pursuant to the terms of such Options or Convertible
Securities in effect on the date immediately preceding the Issuance Date and
such Options or Convertible Securities are not amended after the date
immediately preceding the Issuance Date), for a consideration per share less
than a price (the "Applicable Price") equal to the higher of the Current Market
Price and the Conversion Price, each as in effect immediately prior to such
issuance, then immediately after such issue or sale, the Conversion Price then
in effect shall be reduced to an amount equal to the product of (1) the
Conversion Price in effect immediately prior to such issue or sale and (2) the
quotient of (A) the sum of (x) the product of the Applicable Price and the
number of shares of Common Stock Deemed Outstanding immediately prior to such
issue or sale and (y) the consideration, if any, received by the Corporation
upon such issue or sale, divided by (B) the product of (x) the Applicable Price
multiplied by (y) the number of shares of Common Stock Deemed Outstanding
immediately after such issue or sale. For purposes of determining the adjusted
Conversion Price under this Section 8(e)(i), the following provisions shall be
applicable:

                          (A) Issuance of Options. If the Corporation in any
manner grants or sells any Options and the lowest price per share for which one
share of Common Stock is issuable upon the exercise of any such Option or upon
conversion, exchange or exercise of any Convertible Securities issuable upon
exercise of such Option is less than the Applicable Price, then such share of
Common Stock shall be deemed to be outstanding and to have been issued and sold
by the Corporation at the time of the granting or sale of such Option for such
price per share. For purposes of this Section 8(e)(i)(A), the "lowest price per
share for which one share of Common Stock is issuable upon the exercise of any
such Option or upon conversion, exchange or exercise of any Convertible
Securities issuable upon exercise of such Option" shall be equal to the sum of
the lowest amounts of consideration (if any) received or receivable by the
Corporation with respect to any one share of Common Stock (disregarding, prior
to its occurrence, any potential adjustment thereto described in Section
8(e)(i)(C) unless and until the same shall occur) upon granting or sale of the
Option, upon exercise of the Option and upon conversion, exchange or exercise of
any Convertible Security issuable upon exercise of such Option. No further
adjustment of the Conversion Price shall be made upon the actual issuance of
such Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual issuance of such Common Stock upon conversion,
exchange or exercise of such Convertible Securities.

                          (B) Issuance of Convertible Securities. If the
Corporation in any manner issues or sells any Convertible Securities and the
lowest price per share for which one share of Common Stock is issuable upon such
conversion, exchange or exercise thereof is less than the Applicable Price, then
such share of Common Stock shall be

                                       21



deemed to be outstanding and to have been issued and sold by the Corporation at
the time of the issuance of sale of such Convertible Securities for such price
per share. For the purposes of this Section 8(e)(i)(B), the "lowest price per
share for which one share of Common Stock is issuable upon such conversion,
exchange or exercise" shall be equal to the sum of the lowest amounts of
consideration (if any) received or receivable by the Corporation with respect to
any one share of Common Stock (disregarding, prior to its occurrence, any
potential adjustment thereto described in Section 8(e)(i)(C) unless and until
the same shall occur) upon the issuance or sale of the Convertible Security and
upon the conversion, exchange or exercise of such Convertible Security. No
further adjustment of the Conversion Price shall be made upon the actual
issuance of such Common Stock upon conversion, exchange or exercise of such
Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustment of the
Conversion Price had been or are to be made pursuant to other provisions of this
Section 8(e)(i), no further adjustment of the Conversion Price shall be made by
reason of such issue or sale.

               (C) Change in Option Price or Rate of Conversion. If the purchase
or exercise price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion, exchange or exercise of any Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable or exercisable for Common Stock changes at any time, the
Conversion Price in effect at the time of such change shall be adjusted to the
Conversion Price which would have been in effect at such time had such Options
or Convertible Securities provided for such changed purchase price, additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold. For purposes of this Section 8(e)(i)(C), if
the terms of any Option or Convertible Security that was outstanding as of the
date of issuance of the Preferred Shares are changed in the manner described in
the immediately preceding sentence, then such Option or Convertible Security and
the Common Stock deemed issuable upon exercise, conversion or exchange thereof
shall be deemed to have been issued as of the date of such change.
Notwithstanding the foregoing, no adjustment shall be made if such adjustment
would result in an increase of the Conversion Price then in effect.

               (D) Calculation of Consideration Received. In case any Option is
issued in connection with the issue or sale of other securities of the
Corporation, together comprising one integrated transaction in which no specific
consideration is allocated to such Options by the parties thereto, the Options
will be deemed to have been issued for a per Option or per unit, as applicable,
consideration of $0.01. If any Common Stock, Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the
consideration received therefor will be deemed to be the gross amount received
by the Corporation therefor. If any Common Stock, Options or Convertible
Securities are issued or sold for a consideration other than cash, the amount of
the consideration other than cash received by the Corporation will be the fair
value of such consideration, except where such consideration consists of
marketable securities, in which case the amount of consideration received by the
Corporation will be the arithmetic average of the Closing Sale Prices of such
securities during the ten (10) consecutive trading days ending on the date of
receipt of such securities. The fair value of any consideration other than cash
or securities will be determined jointly by the Corporation and the holders of
at least 51% of the Preferred Shares then outstanding. If such parties are
unable to reach agreement within ten (10) days after the occurrence of an event

                                       22



requiring valuation (the "Valuation Event"), the fair value of such
consideration will be determined within five Business Days after the tenth
(10th) day following the Valuation Event by an independent, nationally
recognized investment banking firm selected by the Corporation and the holders
of at least 51% of the Preferred Shares then outstanding. The determination of
such appraiser shall be deemed binding upon all parties absent manifest error
and the fees and expenses of such appraiser shall be borne by the Corporation.

                     (E) Record Date. If the Corporation takes a record of the
holders of Common Stock for the purpose of entitling them (1) to receive a
dividend or other distribution payable in Common Stock, Options or Convertible
Securities or (2) to subscribe for or purchase Common Stock, Options or
Convertible Securities, then such record date will be deemed to be the date of
the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

               (ii)  Adjustment of Conversion Price upon Subdivision or
Combination of Common Stock. If the Corporation at any time subdivides (by any
stock split, stock dividend, recapitalization or otherwise) its outstanding
shares of Common Stock into a greater number of shares, the Conversion Price in
effect immediately prior to such subdivision will be proportionately reduced. If
the Corporation at any time combines (by combination, reverse stock split or
otherwise) its outstanding shares of Common Stock into a smaller number of
shares and the Conversion Price in effect immediately prior to such combination
will be proportionately increased.

               (iii) Adjustment of Conversion Price on Adjustment Date. In
addition to any other adjustment to the Conversion Price provided for in this
Certificate of Vote, if (A) the Consolidated EBITDA of the Corporation (as such
term is defined in the Financing Agreement), for the Fiscal Year ending December
31, 2003 is not greater than $115 million, as certified in writing by the chief
financial officer of the Corporation to each holder of Preferred Shares as soon
as is available, but not later than March 30, 2004 (the "2004 Consolidated
EBITDA Certificate") and (B) the arithmetic average of the Closing Sale Prices
of the Common Stock during the Adjustment Measuring Period is less than $27.50
(appropriately adjusted to reflect any stock dividend, stock split, stock
combination or other similar transaction occurring from and after the Issuance
Date), then the Conversion Price for the Preferred Shares shall be reduced
effective as of the Adjustment Date to an amount equal to the Adjustment Price,
subject to further adjustment as provided in this Certificate of Vote. If any
holder of Preferred Shares disputes any calculation by the Corporation required
by this Section 8(e)(iii), (including, without limitation, the Corporation's
calculation of Consolidated EBITDA contained in the 2004 Consolidated EBITDA
Certificate), such holder shall deliver to the Corporation (and the Corporation
shall immediately thereafter deliver such notice to each other holder of
Preferred Shares) within ten (10) Business Days of such holder's receipt of the
2004 Consolidated EBITDA Certificate a written notice of such dispute describing
the basis for such dispute. If the Corporation and the disputing holder(s) of
Preferred Shares cannot arrive at a compromise to such dispute within five (5)
Business Days of the Corporation's receipt of written notice thereof from the
disputing holder(s), then such dispute shall be resolved in accordance with the
procedures set forth in Section 8(c)(iii) hereof.

                                       23



               (iv) If the Corporation, at any time while Preferred Shares are
outstanding, shall distribute to all holders of Common Stock (and not to the
holders of Preferred Shares) evidences of its indebtedness or assets or rights
or warrants to subscribe for or purchase any security, then in each such case
the Conversion Price at which each share of Preferred Stock shall thereafter be
convertible shall be determined by multiplying the Conversion Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the Closing Sale Price of a share of Common Stock determined as of the
record date mentioned above, and of which the numerator shall be such Closing
Sale Price on such record date less the then fair market value at such record
date of the portion of such assets or evidence of indebtedness so distributed
applicable to one outstanding share of Common Stock as determined by the Board
in good faith. If any holder of Preferred Shares shall dispute the findings of
the Corporation's Board, then such fair market value shall be determined in
accordance by a nationally recognized investment banking firm selected by the
Corporation and approved by the holders of not less than 51% of the then
outstanding Preferred Shares in accordance with Section 8(c)(iii). In either
case the adjustments shall be described in a statement provided to each holder
of Preferred Shares of the portion of assets or evidences of indebtedness so
distributed or such subscription rights applicable to one share of Common Stock.
Such adjustment shall be made whenever any such distribution is made and shall
become effective immediately after the record date mentioned above.

               (v)  Other Events. If any event occurs of the type contemplated
by the provisions of this Section 8(e) but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features), then the
Corporation's Board of Directors will make an appropriate adjustment in the
Conversion Price so as to protect the rights of the holders of the Preferred
Shares; provided that no such adjustment will increase the Conversion Price as
otherwise determined pursuant to this Section 8(e).

               (vi) Notices.

                    (A) Whenever the Conversion Price is required to be adjusted
as provided herein, the Corporation (1) shall immediately compute the Conversion
Price, (2) shall prepare a certificate signed by the Corporation's Treasurer
setting forth such Conversion Price and showing in detail the facts upon which
such adjustment is based, which certificate shall be certified by the
independent public accountants regularly employed by the Corporation (and
corrected, if such accountants determine that the Corporation's certification is
incorrect), and (3) shall mail a copy of such certificates to each holder of
record of then outstanding Preferred Shares. A copy of such certificate shall
also forthwith be filed with the Corporation's Transfer Agent. Until further
adjusted, the Conversion Price shall be as set forth in such certificate. In the
case of a dispute as to the determination of such adjustment between the
Corporation and any holder of Preferred Shares, then such dispute shall be
resolved in accordance with the procedures set forth in Section 8(c)(iii).

                    (B) The Corporation will give written notice to each holder
of Preferred Shares at least ten (10) Business Days prior to the date on which
the Corporation closes its books or takes a record (1) with respect to any
dividend or distribution

                                       24



upon the Common Stock, (2) with respect to any pro rata subscription offer to
holders of Common Stock or (3) for determining rights to vote with respect to
any Organic Change.

                        (C) The Corporation will also give written notice to
each holder of Preferred Shares at least ten (10) Business Days prior to the
date on which any Organic Change, dissolution or liquidation will take place.

           9. Voting Rights; Board Observation Rights.

              (a) Voting Rights. Except as may be otherwise provided in this
Certificate of Vote or required by law, the Preferred Shares shall vote together
with all other classes and series of stock of the Corporation as a single class
on all actions to be taken by the stockholders of the Corporation. Each
Preferred Share shall have a number of votes, subject to reduction pursuant to
Section 11 hereof, equal to the quotient determined by dividing (a) the number
of shares of Common Stock into which all of the outstanding Preferred Shares are
then convertible in accordance with Section 8 (but subject to the limitation in
Section 11) divided by (b) the number of Preferred Shares then outstanding. Each
holder of Preferred Shares shall be entitled to notice of any stockholders'
meeting in accordance with the By-Laws of the Corporation.

              (b) Board Observation Rights. For so long as Oak Hill Advisors,
Inc. ("Oak Hill") and its Affiliates and funds and accounts that Oak Hill and
its Affiliates control or advise own in the aggregate not less than 2,500
Preferred Shares (subject to adjustment for any stock split, subdivision,
combination or other similar transaction), Oak Hill shall be entitled to appoint
one (1) designee who shall be entitled to observe the meetings of the Board of
Director of the Corporation in a non-voting capacity. Such observer shall have
full rights to attend all meetings of the Board of Directors of the Corporation
and all meetings (whether such meetings are formal or informal, are convened in
person, telephonically, or via any other telecommunication means) of any
committee or subcommittee of the Board of Directors of the Corporation,
including, without limitation, any executive, compensation, governance,
nominating and audit committee. In connection with the rights set forth in this
Section 9(b), the Corporation shall (i) provide all materials distributed to the
members of the Board of Directors of the Company (and any committee or
subcommittee thereof) to each Person designated by Oak Hill hereunder at the
same time such materials are distributed to other Board, committee or
subcommittee members and (ii) pay all reasonable expenses of such Person to
attend the meetings of the Board of Directors (and any committee or subcommittee
thereof).

          10. Protective Provisions. The Corporation shall not, directly or
indirectly, without the affirmative vote or written consent of the holders of
not less than 51% of the then outstanding Preferred Shares, voting or consenting
as a separate class:

              (a) enter into, renew, extend or be a party to, or permit any of
its Subsidiaries to enter into, renew, extend or be a party to, any transaction
or series of related transactions (including, without limitation, the purchase,
sale, lease, transfer or exchange of property or assets of any kind or the
rendering of services of any kind) with any Affiliate, except (1) in the
ordinary course of business in a manner and to an extent consistent with past
practice and necessary or desirable for the prudent operation of its business,
for fair consideration and on

                                       25



terms no less favorable to it or its Subsidiaries than would be obtainable in a
comparable arm's length transaction with a Person that is not an Affiliate
thereof, (2) transactions with another wholly-owned Subsidiary of the
Corporation or the Corporation and (3) transactions permitted by Section 10(f)
hereof;

              (b) (1) declare or pay any dividend or other distribution, direct
or indirect, on account of any Capital Stock of the Corporation or any of its
Subsidiaries, now or hereafter outstanding, (2) make any repurchase, redemption,
retirement, defeasance, sinking fund or similar payment, purchase or other
acquisition for value, direct or indirect, of any Capital Stock of any of the
Corporation or any of its Subsidiaries, now or hereafter outstanding, (3) make
any payment to retire, or to obtain the surrender of, any outstanding warrants,
options or other rights for the purchase or acquisition of shares of any class
of Capital Stock of any of the Corporation or any of its Subsidiaries, now or
hereafter outstanding, (4) return any Capital Stock to any shareholders or other
equity holders of any of the Corporation or any of its Subsidiaries, or make any
other distribution of property, assets, shares of Capital Stock, warrants,
rights, options, obligations or securities thereto as such or (5) pay any
management fees or any other fees or expenses (including the reimbursement
thereof by any of the Corporation or any of its Subsidiaries) pursuant to any
management, consulting or other services agreement to any of the shareholders or
other equity holders of any of the Corporation or any of its Subsidiaries or
other Affiliates, or to any other Subsidiaries or Affiliates of the Corporation;
provided, however, (A) any Subsidiary of the Corporation may pay dividends to
the Corporation or another Subsidiary of the Corporation (B) the Corporation may
pay dividends on its outstanding common Capital Stock in the form of common
Capital Stock, provided that an adjustment for such payment is provided for in
Section 8(e) hereof, (C) the Corporation may pay cash dividends in the annual
amount of $4.00 per share per twelve-month period upon each of the 112,000
shares of the Corporation's Series B Preferred Stock which are currently
outstanding, and (D) the Corporation may accrue Dividends and make Cash Dividend
Payments to the holders of Preferred Shares in the manner provided in Section 4
hereof provided that, in each case of clauses (A) through (D) above, no payment
shall be made if Section 7.02(h) of the Financing Agreement would prohibit such
payment;

              (c) create, incur, assume, guarantee or suffer to exist, or
otherwise become or remain liable with respect to, or permit any of its
Subsidiaries to create, incur, assume, guarantee or suffer to exist or otherwise
become or remain liable with respect to, any Indebtedness other than Permitted
Indebtedness;

              (d) create, incur, assume or suffer to exist, or permit any of its
Subsidiaries to create, incur, assume or suffer to exist, any Lien upon or with

permit any of its Subsidiaries to assign or otherwise transfer, any account or
other right to receive income; other than, as to all of the above, Permitted

amalgamate with any Person, or convey, sell, lease or sublease, transfer or
otherwise dispose of, whether in one transaction or a series of related

or otherwise acquire, whether in one transaction or a series of related
transactions, all or substantially all of the assets of any Person (or any
division thereof) (or agree to do any of the foregoing), or permit any of its

                      (i)  any direct or indirect wholly-owned Subsidiary of the
Corporation may be merged into any other direct or indirect wholly-owned
Subsidiary of the Corporation, or may consolidate with another direct or
indirect wholly-owned Subsidiary of the Corporation, so long as no other
provision of this Certificate of Vote would be violated thereby; and

                      (ii) any of the Corporation and its Subsidiaries may (A)

the conditions of Section 7.02(c)(ii) of the Financing Agreement are satisfied.

                  (f) Make or commit or agree to make any loan, advance,
guarantee of obligations, other extension of credit or capital contributions to,

respective wholly-owned Subsidiaries and by such Subsidiaries to it, made in the
ordinary course of business, provided that the aggregate principal amount of
such investments made in or to the Loan Parties' Subsidiaries organized outside
of the United States (exclusive of (A) investments in the Capital Stock of such
Subsidiaries resulting from the allocation of the consideration paid by the Loan
Parties for the CSD Acquisition Assets (as defined in the Financing Agreement)
and (B) Indebtedness incurred by a Loan Party on behalf of one or more of its
Subsidiaries which is permitted under clause (i) of the definition of "Permitted

under the laws of a Canadian province, $5,000,000 or, in the case of any other
Subsidiary organized outside the

                                       27

the amount permitted in any Fiscal Year under Section 7.02(g) of the Financing
Agreement;

                   (h) Create or otherwise cause, incur, assume, suffer or
permit to exist or become effective any consensual encumbrance or restriction of

that nothing in any of clauses (i) through (iv) of this Section 10(h) shall
prohibit or restrict compliance with:

                          (A) the Financing Agreement, the Revolving Credit
Agreement, or any other agreement or instrument entered into in connection
therewith;

                          (B) any agreements in effect on the Issuance Date and
described on Schedule 7.02(k) to the Financing Agreement;

                          (C) any applicable law, rule or regulation (including,
without limitation, applicable currency control laws and applicable state

circumstances);

                          (D) in the case of clause (iv) any agreement setting

property or asset that is a lease, license, conveyance or contract of similar
property or assets; or

                          (E) in the case of clause (iv) any agreement,
instrument or other document evidencing a Permitted Lien from restricting on
customary terms the transfer of any property or assets subject thereto.

                   (i) assume, or accept any assignment of, directly or
indirectly, after the Issuance Date any contract, agreement or obligation of
Safety-Kleen Corp. or its Affiliates or Subsidiaries containing or otherwise
imposing on the Corporation or any of its Affiliates or Subsidiaries any
material indemnification or guarantee obligation, other than those contracts and
agreements listed in a schedule delivered prior to the Effective Date to each
holder of Preferred Shares as of the Effective Date;

                   (j) amend, alter, change, repeal or waive any provision of
its Articles of Organization (whether by way of a Certificate of Vote or
otherwise) or this Certificate of Vote

                                       28



or its By-laws in any manner (whether by merger, consolidation or otherwise),
that would adversely affect the rights, preferences or privileges of the
Preferred Shares;

                    (k) create or authorize the creation of or issue (including,
without limitation, by way of recapitalization), or obligate itself or any
Subsidiary to authorize or issue any shares of any series of preferred stock of
the Corporation or any such Subsidiary, or any other security exercisable for or
convertible into any shares of any series of preferred stock of the Corporation
or any Subsidiary, whether any such creation or authorization shall be by means
of amendment of the Articles of Organization (whether by way of a Certificate of
Vote or otherwise) or of this Certificate of Vote or by merger, consolidation or
otherwise;

                    (l) issue or authorize the issuance of any Preferred Shares
after the Issuance Date;

                    (m) issue or authorize the issuance of any shares of Series
B Preferred Stock of the Corporation after the Issuance Date;

                    (n) modify or amend the terms of the Series B Preferred
Stock in a manner that could reasonably be expected to adversely affect the
rights of the holders of Preferred Shares; or

                    (o) enter into any contract, agreement, commitment or
understanding with respect to any of the foregoing.

               If the Company shall have breached or defaulted with respect to
any of the covenants set forth in this Section 10, and such breach has not been
cured, if curable, within 30 days of written notice to the Company thereof
(each, a "Covenant Default"), then, immediately upon the occurrence of such
Covenant Default, (i) the Dividend Rate in effect on the date of the Covenant
Default shall increase by six percent (6%) until the later of (A) the six-month
anniversary of the date of the occurrence of the Covenant Default and (B) the
date on which such Covenant Default is cured and (ii) the Conversion Price shall
automatically be adjusted (subject to further adjustment pursuant to this
Certificate of Vote subsequent to such adjustment) to an amount equal to (A) the
Adjustment Price, in the event the Conversion Price in effect on the date of the
Covenant Default is greater than the Adjustment Price and (B) the product of (I)
0.9 and (II) the Conversion Price in effect on the date of the Covenant Default,
in the event the Conversion Price in effect on the date of the Covenant Default
is less than or equal to the Adjustment Price.

               11. Limitation on Number of Conversion Shares. Notwithstanding
anything to the contrary contained herein, (a) the Corporation shall not be
obligated to issue any shares of Common Stock upon conversion of the Preferred
Shares if the issuance of such shares of Common Stock would exceed that number
of shares of Common Stock which the Corporation may issue upon conversion of the
Preferred Shares without breaching the Corporation's obligations under the rules
or regulations of the Principal Market, or the market or exchange where the
Common Stock is then traded (the "Exchange Cap") and (b) the holders of
Preferred Shares may not exercise voting power with respect to any Preferred
Shares in accordance with Section 9 hereof on any matter brought before all
holders of Capital Stock of the Corporation to

                                       29



the extent that voting such Preferred Shares shall cause the Corporation to
breach its obligations under the Exchange Cap, except that such limitations
shall not apply in the event that the Corporation (i) obtains the approval of
its stockholders as required by the applicable rules of the Principal Market (or
any successor rule or regulation) for issuances of Common Stock in excess of
such amount, or (ii) obtains a written opinion from outside counsel to the
Corporation that such approval is not required, which opinion shall be
reasonably satisfactory to the holders of at least 51% of the Preferred Shares
then outstanding. Until such approval or written opinion is obtained, (A) no
purchaser of Preferred Shares pursuant to the Purchase Agreement (the
"Purchasers") shall be issued, upon conversion of Preferred Shares, shares of
Common Stock and (B) no Purchaser shall have the right to exercise voting rights
on matters brought before all holders of Capital Stock in accordance with
Section 9 hereof in respect of Preferred Shares in an amount greater than the
product of (1) the Exchange Cap amount multiplied by (2) a fraction, the
numerator of which is the number of Preferred Shares issued to such Purchaser
pursuant to the Purchase Agreement and the denominator of which is the aggregate
amount of all the Preferred Shares issued to the Purchasers pursuant to the
Purchase Agreement (the "Cap Allocation Amount"). In the event that any
Purchaser shall sell or otherwise transfer any of such Purchaser's Preferred
Shares, the transferee shall be allocated a pro rata portion of such Purchaser's
Cap Allocation Amount. In the event that any holder of Preferred Shares shall
convert all of such holder's Preferred Shares into a number of shares of Common
Stock which, in the aggregate, is less than such holder's Cap Allocation Amount,
then the difference between such holder's Cap Allocation Amount and the number
of shares of Common Stock actually issued to such holder shall be allocated to
the respective Cap Allocation Amounts of the remaining holders of Preferred
Shares on a pro rata basis in proportion to the number of Preferred Shares then
held by each such holder. If at any time when a holder of Preferred Shares shall
deliver a Conversion Notice pursuant to Section 8(c) hereof the Corporation
shall be prohibited pursuant to the provisions of this Section 11 from issuing
all or any portion of the Conversion Shares issuable pursuant to such Conversion
Notice, then the Corporation shall pay in immediately available funds to the
holder within two (2) Business Days of the date of delivery of such Conversion
Notice, an amount in cash equal to the product of (x) the number of shares of
Common Stock which could not be issued by virtue of the limitations contained in
this Section 11 multiplied by (y) the average of the Closing Sale Prices of the
Common Stock on each of the five (5) trading days immediately preceding the date
of delivery of such Conversion Notice, and concurrent with, and subject to such
payment by the Corporation, the number of Preferred Shares held by such holder
shall be reduced on the books and records of the Corporation in accordance with
Section 8(c)(vi) by the number of Preferred Shares that were subject to the
Conversion Notice and could not be converted by virtue of the limitations of
this Section 11.

               12. Lost or Stolen Certificates. Upon receipt by the Corporation
of evidence reasonably satisfactory to the Corporation of the loss, theft,
destruction or mutilation of any Preferred Stock Certificates representing the
Preferred Shares, and, in the case of loss, theft or destruction, of an
indemnification undertaking by the holder to the Corporation in customary form
and, in the case of mutilation, upon surrender and cancellation of the Preferred
Stock Certificate(s), the Corporation shall execute and deliver to the holder
new preferred stock certificate(s) of like tenor and date.

               13. Reservation of Shares. The Corporation shall, so long as any
of the Preferred Shares are outstanding, take all action necessary to reserve
and keep available out of its

                                       30



authorized and unissued Common Stock, solely for the purpose of effecting the
conversions of the Preferred Shares, such number of shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all of the
Preferred Shares then outstanding (without regard to any limitations on
conversions) under the terms of this Certificate of Vote as then in effect. The
initial number of shares of Common Stock reserved for conversions of the
Preferred Shares and each increase in the number of shares so reserved shall be
allocated pro rata among the holders of the Preferred Shares based on the number
of Preferred Shares held by each holder at the time of issuance of the Preferred
Shares or increase in the number of reserved shares, as the case may be. In the
event a holder shall sell or otherwise transfer any of such holder's Preferred
Shares, each transferee shall be allocated a pro rata portion of the number of
reserved shares of Common Stock reserved for such transferor. Any shares of
Common Stock reserved and allocated to any Person which ceases to hold any
Preferred Shares shall be allocated to the remaining holders of Preferred
Shares, pro rata based on the number of Preferred Shares then held by such
holders.

               14. No Impairment. The Corporation shall not, by amendment of its
Articles of Organization or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of the Preferred Shares set forth herein, but will at all times in
good faith assist in the carrying out of all terms and in the taking of all
action that may be necessary or appropriate in order to protect the rights of
the holders of then outstanding Preferred Shares against dilution or other
impairment. Without limiting the generality of the foregoing, the Corporation
(a) shall not increase the par value of any shares of stock receivable on the
conversion of Preferred Shares above the amount payable therefor on such
conversion and (b) shall take all action that may be necessary or appropriate in
order that the Corporation may validly and legally issue fully paid and
nonassessable shares of stock on the conversion of all Preferred Shares from
time to time outstanding.

               15. Severability of Provisions. Whenever possible, each provision
of this Certificate of Vote shall be interpreted in a manner as to be effective
and valid under applicable law, but if any provision hereof is held to be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating or otherwise adversely affecting the remaining provisions hereof.
If a court of competent jurisdiction should determine that a provision hereof
would be valid or enforceable if a period of time were extended or shortened or
a particular percentage were increased or decreased, then such court may make
such change as shall be necessary to render the provision in question effective
and valid under applicable law.

               16. Amendment, Waiver or Discharge. Except as otherwise expressly
provided herein, neither this Certificate of Vote nor any term hereof may be
amended, waived, modified, discharged or terminated without the written consent
or affirmative vote of the holders of not less than 51% of the Preferred Shares
then outstanding; provided, however, that no amendment, waiver or consent shall
(a) change or extend the Mandatory Redemption Date, the Redemption Price or the
Conversion Price applicable to any Preferred Shares, in each case without the
written consent of the holder of such Preferred Shares (b) amend, modify or
waive the conversion or redemption rights of any holder of Preferred Shares
without the written consent

                                       31



of such holder or (c) amend, modify or waive this Section 16 without the written
consent of each holder of Preferred shares.

               17. Remedies, Characterizations, Other Obligations, Breaches and
Injunctive Relief. The remedies provided in this Certificate of Votes shall be
cumulative and in addition to all other remedies available under this
Certificate of Vote, at law or in equity (including a decree of specific
performance and/or other injunctive relief). No remedy contained herein shall be
deemed a waiver of compliance with the provisions giving rise to such remedy.
Nothing herein shall limit a holder's right to pursue actual damages for any
failure by the Corporation to comply with the terms of this Certificate of Vote.
The Corporation covenants to each holder of Preferred Shares that there shall be
no characterization concerning this instrument other than as expressly provided
herein. Amounts set forth or provided for herein with respect to payments,
conversion and the like (and the computation thereof) shall be the amounts to be
received by the holder thereof and shall not, except as expressly provided
herein, be subject to any other obligation of the Corporation (or the
performance thereof). The Corporation acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the holders of the
Preferred Shares and that the remedy at law for any such breach may be
inadequate. The Corporation therefore agrees that, in the event of any such
breach or threatened breach, the holders of the Preferred Shares shall be
entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and
without any bond or other security being required.

               18. Failure or Indulgence Not Waiver. No failure or delay on the
part of a holder of Preferred Shares in the exercise of any power, right or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privilege.

               19. Notice. Whenever notice is required to be given under this
Certificate of Vote, unless otherwise provided herein, such notice shall be
given in accordance with Section 8 of the Purchase Agreement (provided that if
the Preferred Shares are not held by a Buyer (as defined in the Purchase
Agreement) then such notice shall be given to the holder of Preferred Shares at
the address set forth on the books and records of the Corporation.

               20. Transfer of Preferred Shares. A holder of Preferred Shares
may assign some or all of the Preferred Shares and the accompanying rights
hereunder held by such holder without the consent of the Corporation; provided
that such assignment is in compliance with applicable securities laws and notice
of such assignment is delivered to the Corporation promptly thereafter.

               21. Preferred Share Register. The Corporation shall maintain at
its principal executive offices (or such other office or agency of the
Corporation as it may designate by notice to the holders of the Preferred
Shares), a register for the Preferred Shares, in which the Corporation shall
record the name and address of the persons in whose name the Preferred Shares
have been issued, as well as the name and address of each transferee. The
Corporation may treat the person in whose name any Preferred Share is registered
on the register as the owner and holder thereof for all purposes,
notwithstanding any notice to the contrary, but in all events recognizing any
properly made transfers.

                                       32
